The Utility of Esophageal Motility Testing in Gastroesophageal Reflux Disease (GERD)

Abstract

Purpose of Review

Here, we discuss how esophageal motor testing plays important roles in patients with suspected gastroesophageal reflux disease (GERD). In addition to guiding appropriate placement of catheters for ambulatory reflux monitoring, esophageal high-resolution manometry (HRM) rules out confounding diagnoses, such as achalasia spectrum disorders, that can present with symptoms similar to that of GERD, but are managed very differently.

Recent Findings

HRM performed with impedance in the post-prandial setting (PP-HRIM) can assess for rumination syndrome or supragastric belching, which should be directed towards behavioral interventions. The recent GERD Classification of Motor Function recommends a hierarchical approach, focusing on (1) the esophagogastric junction (EGJ), (2) the esophageal body, and (3) esophageal contraction reserve, which can be assessed with provocative maneuvers at HRM, such as multiple rapid swallows (MRS). This approach can inform the appropriate tailoring of antireflux surgery. Novel esophageal motility metrics, such as the EGJ-contractile integral from HRM, or post-reflux swallow-induced peristaltic wave indices from 24-h pH-impedance monitoring, may also assist with GERD diagnosis.

Summary

Assessment of esophageal motor function can contribute in a significant manner to the care of patients with suspected GERD, particularly when esophageal symptoms do not improve with antisecretory therapy, and/or when surgical or endoscopic antireflux therapies are under consideration.



Duodenal Chemosensing of Short-Chain Fatty Acids: Implications for GI Diseases

Abstract

Purpose of Review

Short-chain fatty acids (SCFAs), the main bacterial fermentation products in the hindgut of hindgut fermenters, are also present in the foregut lumen. We discuss the impact of SCFAs in the duodenal defense mechanisms and in the gastrointestinal (GI) pathogenesis.

Recent Findings

Luminal SCFAs augment the duodenal mucosal defenses via release of serotonin (5-HT) and glucagon-like peptide-2 (GLP-2) from enteroendocrine cells. Released GLP-2 protects the small intestinal mucosa from nonsteroidal anti-inflammatory drug-induced enteropathy. SCFAs are also rapidly absorbed via SCFA transporters and interact with afferent and myenteric nerves. Excessive SCFA signals with 5-HT3 receptor overactivation may be implicated in the pathogenesis of irritable bowel syndrome symptoms. SCFA production exhibits diurnal rhythms with host physiological responses, suggesting that oral SCFA treatment may adjust the GI clocks.

Summary

SCFAs are not only a source of energy but also signaling molecules for the local regulation of the GI tract and systemic regulation via release of gut hormones. Targeting SCFA signals may be a novel therapeutic for GI diseases and metabolic syndrome.



Gastroduodenal Injury: Role of Protective Factors

Abstract

Purpose of Review

The gastroduodenal mucosal layer is a complex and dynamic system that functions in an interdependent manner to resist injury. We review and summarize the most updated knowledge about gastroduodenal defense mechanisms and specifically address (a) the mucous barrier, (b) membrane and cellular properties, and vascular, hormonal, and (c) gaseous mediators.

Recent Findings

Trefoil factor family peptides play a crucial role in cellular restitution by increasing cellular permeability and expression of aquaporin channels, aiding cellular migration and tissue repair. Additionally, evidence suggests that the symptoms of functional dyspepsia may be attributed to alterations in the duodenum, including low-grade inflammation and increased mucosal permeability.

Summary

The interaction of the various mucosal protective components helps maintain structural and functional homeostasis. There is increasing evidence suggesting that the upper GI microbiota plays a crucial role in the defense mechanisms. However, this warrants further investigation.



The Rise of Colorectal Cancer in Asia: Epidemiology, Screening, and Management

Abstract

Purpose of Review

Colorectal cancer (CRC) remains the third most commonly diagnosed cancer globally, and its incidence and mortality rates have been on the rise in Asia. In this paper, we summarize the recent trends and screening challenges of CRC in this region.

Recent Findings

In 2018, Asia had the highest proportions of both incident (51.8%) and mortality (52.4%) CRC cases (all genders and ages) per 100,000 population in the world. In addition, there has been a rising trend of this disease across Asia with some regional geographic variations. This rise in CRC can be attributed to westernized dietary lifestyle, increasing population aging, smoking, physical inactivity, and other risk factors. In curbing the rising trend, Japan, South Korea, Singapore, and Taiwan have launched nationwide population-based screening programs. CRC screening across this region has been found to be effective and cost-effective compared with no screening at all. The emergence of new therapies has caused a reduction in case fatality; however, these new options have had a limited impact on cure rates and long-term survival due to the great disparity in treatment capacity/resources and screening infrastructures among Asian countries with different degrees of economic development.

Summary

CRC is still rising in Asia, and implementation of screening is necessary for moderate- to high-incidence countries and construction of treatment capacity is the priority task in low-incidence and low-income countries. Unless countries in Asia implement CRC screening, the incidence and mortality rates of this disease will continue to rise especially with the rapidly rising population growth, economic development, westernized lifestyle, and increasing aging.



Nutrition in Cirrhosis

Abstract

Purpose of Review

This review discusses the prevalence of malnutrition in cirrhosis, metabolic functions of the liver and alterations in cirrhosis, malnutrition screening tools, and common macronutrient and micronutrient deficiencies encountered in individuals with chronic liver disease and their impact on morbidity and mortality.

Recent Findings

Several meta-analyses and international society guidelines recommend malnutrition screening and nutrition interventions to improve outcomes in all patients with chronic liver disease given their high risk of malnutrition which is often under recognized.

Summary

Malnutrition is common in individuals with chronic liver disease and has a significant impact on patient outcomes. Thus, it is critical that validated malnutrition screening tools are used routinely in this patient population in order to identify high-risk patients and implement nutrition and exercise interventions early.



Popular Remedies for Esophageal Symptoms: a Critical Appraisal

Abstract

Purpose of Review

Popular remedies are of ongoing interest to patients experiencing common esophageal symptoms, particularly as typical pharmacologic interventions have been subject to increased scrutiny. Herein we summarize the available data regarding potential risks and benefits of several such remedies.

Recent Findings

With emphasis on reflux and non-cardiac chest pain, research is ongoing into the clinical utility and diverse physiologic mechanisms underlying a variety of complementary and alternative modalities, including dietary manipulation, apple cider vinegar, melatonin, acupuncture, and various herbal products (rikkunshito, STW 5, slippery elm, licorice, and peppermint oil, among others).

Summary

A substantial gap persists between anecdotal and empirical understandings of the majority of non-pharmacologic remedies for esophageal symptoms. This landscape of popular treatments nevertheless raises several interesting mechanistic hypotheses and compelling opportunities for future research.



Colonic and Anorectal Manifestations of Systemic Sclerosis

Abstract

Purpose of Review

Systemic sclerosis is a chronic autoimmune disorder commonly involving the gastrointestinal tract, including the colon and anorectum. In this review, we summarize major clinical manifestations and highlight recent developments in physiology, diagnostics, and treatment.

Recent Findings

The exact pathophysiology of systemic sclerosis is unclear and likely multifactorial. The role of the microbiome on gastrointestinal manifestations has led to a better understanding of potential pathogenic gut flora. Carbohydrate malabsorption is common. Evaluation using fecal calprotectin and high-resolution anorectal manometry may broaden our understanding of the etiologies of diarrhea and fecal incontinence and help with early recognition of pathology. Prucalopride, a high-affinity 5HT4 agonist, and pyridostigmine, an acetylcholinesterase inhibitor, may help improve colonic transit in patients with constipation. Intravenous immunoglobulins have been used to target muscarinic receptor antibodies that are believed to contribute to gastrointestinal dysmotility.

Summary

Colonic and anorectal manifestations of systemic sclerosis include constipation, diarrhea, and fecal incontinence, and can diminish quality of life for these patients. Recent studies regarding pathophysiology as well as diagnostic and treatment options are promising. Further targeted studies to facilitate early intervention and better management of refractory symptoms are still needed.



Evaluation and Management of Cirrhotic Patients Undergoing Elective Surgery

Abstract

Purpose of Review

Cirrhotic patients have an increased risk of surgical complications and higher perioperative morbidity and mortality based on the severity of their liver disease. Liver disease predisposes patients to perioperative coagulopathies, volume overload, and encephalopathy. The goal of this paper is to discuss the surgical risk of cirrhotic patients undergoing elective surgeries and to discuss perioperative optimization strategies.

Recent Findings

Literature thus far varies by surgery type and the magnitude of surgical risk. CTP and MELD classification scores allow for the assessment of surgical risk in cirrhotic patients.

Summary

Once the decision has been made to undergo elective surgery, cirrhotic patients can be optimized pre-procedure with the help of a checklist and by the involvement of a multidisciplinary team. Elective surgeries should be performed at hospital centers staffed by healthcare providers experienced in caring for cirrhotic patients. Further research is needed to develop ways to prepare this complicated patient population before elective surgery.



The Status of SEMS Versus Plastic Stents for Benign Biliary Strictures

Abstract

Purpose of Review

Benign biliary strictures can be treated with plastic stents and self-expandable metal stents (SEMS). This review article delineates the latest scientific evidence for their usage.

Recent Findings

Despite evolving literature on both type of stents as treatment modalities of benign biliary strictures, which encompass mainly anastomotic strictures and strictures related to chronic pancreatitis, no final conclusions can be drawn regarding the superiority of a particular stent. SEMS tend to have higher stricture resolution rates and fewer procedural requirements which are partly offset by higher stent migration and stricture recurrence rates compared with plastic stents.

Summary

Additional studies focusing on new SEMS types with anti-migration features as well as cost-effectiveness calculations are necessary for clinical decision-making when treating patients with benign biliary strictures.



Clinical Aspects of Thickeners for Pediatric Gastroesophageal Reflux and Oropharyngeal Dysphagia

Abstract

Purpose of Review

The purpose of this review is to discuss current knowledge and recent findings regarding clinical aspects of thickeners for pediatric gastroesophageal reflux and oropharyngeal dysphagia. We review evidence for thickener efficacy, discuss types of thickeners, practical considerations when using various thickeners, and risks and benefits of thickener use in pediatrics.

Recent Findings

Thickeners are effective in decreasing regurgitation and improving swallowing mechanics and can often be used empirically for the treatment of infants and young children. Adverse effects have been reported, but with careful consideration of appropriate thickener types, desired thickening consistency, and follow-up in collaboration with feeding specialists, most patients have symptomatic improvements.

Summary

Thickeners are typically well tolerated and with few side effects, but close follow-up is needed to make sure patients tolerate thickeners and have adequate symptom improvement.

Lipidology

Editorial introduction
imageNo abstract available

Non-HDL cholesterol should not generally replace LDL cholesterol in the management of hyperlipidaemia
imagePurpose of review Non-HDL cholesterol was originally conceived as a therapeutic target for statin treatment in hypertriglyceridaemia when apolipoprotein B100 assays were not widely available. Recently non-HDL cholesterol has been recommended to replace LDL cholesterol in the clinical management of dyslipidaemia routinely in general medical practice. This is misguided. Recent findings Non-HDL cholesterol is heterogeneous, constituting a mixture of triglyceride-rich VLDL, intermediate density lipoprotein and LDL in which small dense LDL is poorly represented and to which VLDL cholesterol contributes increasingly as triglyceride levels rise. This makes it unsuitable as a goal of lipid-lowering treatment or as an arbiter of who should receive such treatment. Results of trials designed to lower LDL cholesterol are not easily translated to non-HDL cholesterol. Fasting is no longer thought essential for screening the general population for raised LDL cholesterol. ApoB100 measurement also does not require fasting even in rarer more extreme lipoprotein disorders encountered in the Lipid Clinic, provides greater precision and specificity and overcomes the problems posed by LDL and non-HDL cholesterol. It is more easily interpreted both in diagnosis and as a therapeutic goal and it includes SD-LDL. Summary If we are to discourage use of LDL cholesterol, it should be in favour of apoB100 not non-HDL cholesterol.

Update on low-density lipoprotein cholesterol quantification
imagePurpose of review β-Quantification is considered the reference measurement procedure for low-density lipoprotein cholesterol (LDL-C). However, this technique is time-consuming and thus is inappropriate for routine clinical practice. Therefore, the Friedewald equation or homogeneous assays have been widely utilized. As several pitfalls exist with these two methods, a novel method for estimating LDL-C was developed by Martin et al. Recent findings Martin's method uses a strata-specific median for the triglycerides/very low-density lipoprotein cholesterol (VLDL-C) ratio on the basis of triglycerides and non-HDL-C concentrations. Recent studies show that Martin's method better correlates with β-quantification or homogeneous assays compared with the Friedewald equation, especially with values of triglycerides at least 150 mg/dl and/or LDL-CD less than 70 mg/dl. Such findings have also been demonstrated in other ethnic groups (Japanese and Korean) and disease populations, including diabetes and cardiovascular disease, in which the triglycerides/VLDL-C ratio can be affected. Summary For the current therapeutic goal of LDL-C values below 70 mg/dl in high-risk patients, accurate assessment of LDL-C levels at very low levels is required. Martin's method could overcome pitfalls such as underestimation of the Friedewald equation at this level. Further evaluation of the triglycerides/VLDL-C ratio in participants with diverse ethnic backgrounds or clinical conditions would expand the implementation of this novel method.

Recent developments in lipodystrophy
imagePurpose of review Lipodystrophy syndromes have an estimated prevalence of 1.3–4.7 cases per million and as with other rare diseases conducting research can be challenging. The present review highlights recently published work that has provided insights into the field of non-HIV--associated lipodystrophy syndromes. Recent findings Lipodystrophies are a heterogenous group of disorders, as such research is often focused on specific subtypes of the condition. The identification of children carrying LMNA mutations has provided insights into the natural history of FPLD2, specifically that the adipose tissue phenotype predates the onset of puberty. Recent reports of PLIN1 heterozygous null variant carriers and the apparent absence of a lipodystrophy phenotype challenges our understanding of the molecular biology of perilipin 1 and its role in the pathogenesis of FPLD4. With a focus on therapeutics, studies delineating the differential responsiveness of PPARÎł mutants to endogenous and synthetic ligands has illustrated the potential for pharmacogenetics to inform therapeutic decisions in lipodystrophy related to PPARG mutations, whereas robust human studies have provided insight into the food independent metabolic effects of leptin in lipodystrophy. Finally, rare syndromes of lipodystrophy continue to serve as an exemplar for the contribution of genetically determined adipose tissue expandability to metabolic disease in the general population. Summary Lipodystrophy research continues to illuminate our understanding of this rare disease and the possibility that lipodystrophy syndromes and the metabolic syndrome may have shared pathophysiology.

Is hypertriglyceridemia atherogenic?
imagePurpose of review Hypertriglyceridemia occurs mainly because of metabolic disorders secondary to diabetes, alcohol intake, and/or overweight. Genetic factors have also been clearly identified in most severe cases. Triglycerides are generally considered as 'bystanders' for cardiovascular diseases. However, biological and basic research provides strong data suggesting that triglyceride-rich lipoproteins could be involved in the pathophysiology of cardiovascular diseases. Recent findings The REDUCE-IT trial recently showed that icosapent ethyl reduces major cardiovascular events and related death. Summary For many years, low-density lipoproteins (LDLs) have been considered the Holy Grail for atherosclerotic cardiovascular disease management. New data from basic research in biology, epidemiology, genetics, and preliminary clinical trials support the hypothesis that triglyceride-rich lipoproteins could be the causal factors for atherosclerotic cardiovascular disease; hence, triglyceride should be taken into consideration in the management of these patients. Omega-3-fatty acids used in the REDUCE-IT trial reduced the residual cardiovascular risk efficiently beyond statins. However, its effect has to be completely understood as it seems to be unrelated to LDLc or triglyceride reduction, but linked to pleiotropic effects involving inflammation, platelet adhesion, and plaque instability reduction, paving the way for trials that will target more specific potential pathophysiologic pathways.

Monogenic, polygenic, and oligogenic familial hypercholesterolemia
imagePurpose of review Familial hypercholesterolemia has long been considered a monogenic disorder. However, recent advances in genetic analyses have revealed various forms of this disorder, including polygenic and oligogenic familial hypercholesterolemia. We review the current understanding of the genetic background of this disease. Recent findings Mutations in multiple alleles responsible for low-density lipoprotein regulation could contribute to the development of familial hypercholesterolemia, especially among patients with mutation-negative familial hypercholesterolemia. In oligogenic familial hypercholesterolemia, multiple rare genetic variations contributed to more severe familial hypercholesterolemia. Summary Familial hypercholesterolemia is a relatively common 'genetic' disorder associated with an extremely high risk of developing coronary artery disease. In addition to monogenic familial hypercholesterolemia, different types of familial hypercholesterolemia, including polygenic and oligogenic familial hypercholesterolemia, exist and have varying degrees of severity. Clinical and genetic assessments for familial hypercholesterolemia and clinical risk stratifications should be performed for accurate diagnosis, as should cascade screening and risk stratification for the offspring of affected patients.

Inheritance of high and low HDL: mechanisms and management
imagePurpose of review The inverse association between plasma high-density lipoprotein cholesterol (HDL-C) concentration and the incidence of cardiovascular disease (CVD) has been unequivocally proven by many epidemiological studies. There are several genetic disorders affecting HDL-C plasma levels, either providing atheroprotection or predisposing to premature atherosclerosis. However, up to date, there has not been any pharmacological intervention modulating HDL-C levels, which has been clearly shown to prevent the progression of CVD. Thus, clarifying the exact underlying mechanisms of inheritance of these genetic disorders that affect HDL is a current goal of the research, as key roles of molecular components of HDL metabolism and function can be revealed and become targets for the discovery of novel medications for the prevention and treatment of CVD. Recent findings Primary genetic disorders of HDL can be either associated with longevity or, in contrast, may lead to premature CVD, causing high morbidity and mortality to their carriers. A large body of recent research has closely examined the genetic disorders of HDL and new promising therapeutic strategies have been developed, which may be proven beneficial in patients predisposed to CVD in the near future. Summary We have reviewed recent findings on the inheritance of genetic disorders associated with high and low HDL-C plasma levels and we have discussed their clinical features, as well as information about new promising HDL-C-targeted therapies that are under clinical trials.

High-density lipoprotein: our elusive friend
imagePurpose of review Despite advances in the research on HDL composition (lipidomics and proteomics) and functions (cholesterol efflux and antioxidative capacities), the relationship between HDL compositional and functional properties is not fully understood. We have reviewed the recent literature on this topic and pointed out the difficulties which limit our understanding of HDL's role in cardiovascular disease (CVD). Recent findings Though current findings strongly support that HDL has a significant role in CVD, the underlying mechanisms by which HDL mitigates CVD risk are not clear. This review focuses on studies that investigate the cell-cholesterol efflux capacity and the proteomic and lipidomic characterization of HDL and its subfractions especially those that analyzed the relationship between HDL composition and functions. Summary Recent studies on HDL composition and HDL functions have greatly contributed to our understanding of HDL's role in CVD. A major problem in HDL research is the lack of standardization of both the HDL isolation and HDL functionality methods. Data generated by different methods often produce discordant results on the particle number, size, lipid and protein composition, and the various functions of HDL.

Role of serum amyloid A in atherosclerosis
imagePurpose of review Acute phase serum amyloid A (SAA) is persistently elevated in chronic inflammatory conditions, and elevated levels predict cardiovascular risk in humans. More recently, murine studies have demonstrated that over-expression of SAA increases and deficiency/suppression of SAA attenuates atherosclerosis. Thus, beyond being a biomarker, SAA appears to play a causal role in atherogenesis. The purpose of this review is to summarize the data supporting SAA as a key player in atherosclerosis development. Recent findings A number of pro-inflammatory and pro-atherogenic activities have been ascribed to SAA. However, the literature is conflicted, as recombinant SAA, and/or lipid-free SAA, used in many of the earlier studies, do not reflect the activity of native human or murine SAA, which exists largely lipid-associated. Recent literatures demonstrate that SAA activates the NLRP3 inflammasome, alters vascular function, affects HDL function, and increases thrombosis. Importantly, SAA activity appears to be regulated by its lipid association, and HDL may serve to sequester and limit SAA activity. Summary SAA has many pro-inflammatory and pro-atherogenic activities, is clearly demonstrated to affect atherosclerosis development, and may be a candidate target for clinical trials in cardiovascular diseases.

The future of apolipoprotein E mimetic peptides in the prevention of cardiovascular disease
imagePurpose of review This review aims to discuss the recent developments in the area of apolipoprotein E (apoE) mimetics and their therapeutic potential for treating cardiovascular disease, the leading cause of mortality worldwide. Recent findings Ongoing research efforts target the development of novel therapies that would not only reduce circulating levels of atherogenic lipoproteins, but could also increase high density lipoprotein cholesterol (HDL-C) levels and/or improve HDL function. Among them, synthetic peptides that mimic the structure of natural human apoE, a component of triglyceride-rich lipoproteins and HDL, have been designed and proven to be functionally similar to apoE. In specific, apoE mimetic peptides mediate hepatic clearance of circulating atherogenic lipoproteins, dramatically reduce plasma cholesterol, and lead to attenuation of atherosclerosis development in vivo. These peptides also exhibit pleiotropic antiatherogenic properties, such as macrophage cholesterol efflux capacity, as well as anti-inflammatory and antioxidative functions. Summary ApoE mimetics are undergoing preclinical and clinical evaluation with promising results to date that render them attractive candidates in cardiovascular disease prevention and treatment.

Sexually Transmitted Diseases

The National Network of Sexually Transmitted Disease Clinical Prevention Training Centers Turns 40—A Look Back, a Look Ahead
imageSince 1979, the National Network of Sexually Transmitted Disease (STD) Clinical Prevention Training Centers (NNPTC) has provided state-of-the-art clinical and laboratory training for STD prevention across the United States. This article provides an overview of the history and activities of the NNPTC from its inception to present day, and emphasizes the important role the network continues to play in maintaining a high-quality STD clinical workforce. Over time, the NNPTC has responded to changing STD epidemiological patterns, technological advances, and increasing private-sector care-seeking for STDs. Its current structure of integrated regional and national training centers allows NNPTC members to provide dynamic, tailored responses to STD training needs across the country.

Sexually Transmitted Disease Partner Services Costs, Other Resources, and Strategies Across Jurisdictions to Address Unique Epidemic Characteristics and Increased Incidence
imageBackground Sexually transmitted disease (STD) partner services (PS) are a core component of STD programs. Data on costs are needed to support PS programming. Methods In Washington State STD PS programs, disease intervention specialists (DIS) conduct telephone-based interviews and occasional field visits, offer expedited partner therapy to heterosexuals with gonorrhea or chlamydia, and promote human immunodeficiency virus (HIV) testing, preexposure prophylaxis, and HIV care. We conducted activity-based microcosting of PS, including: observational and self-reported time studies and interviews. We analyzed cost, surveillance, and service delivery data to determine costs per program outcomes. Results In King, Pierce, and Spokane counties, respectively, DIS allocated 6.5, 6.4, and 28.8 hours per syphilis case and 1.5, 1.6, and 2.9 hours per gonorrhea/chlamydia case, on average. In 2016, each full-time DIS investigated 270, 268, and 61 syphilis and 1177, 1105, and 769 gonorrhea/chlamydia cases. Greater than 80% of syphilis cases in King and Pierce were among men who have sex with men versus 38% in Spokane. Disease intervention specialists spent 12% to 39% of their time actively interviewing cases and notifying partners (clients), and the remaining time locating clients, coordinating and verifying care, and managing case reports. Time spent on expedited partner therapy, HIV testing, and referrals to HIV treatment or preexposure prophylaxis, was minimal (<5 minutes per interview) at locations with resources outside PS staff. Program cost-per-interview ranged from US $527 to US $2210 for syphilis, US $219 to US $484 for gonorrhea, and US $164 to US $547 for chlamydia. Discussion The STD PS resource needs depended on epidemic characteristics and program models. Integrating HIV prevention objectives minimally impacted PS-specific program costs. Results can inform program planning, future budget impact, and cost-effectiveness analyses.

Changes in Patient Visits After the Implementation of Insurance Billing at a Sexually Transmitted Diseases Clinic in a Medicaid Expansion State
imageBackground Medicaid expansion has led to unique opportunities for sexually transmitted disease (STD) clinics to improve the sustainability of services by billing insurance. We evaluated changes in patient visits after the implementation of insurance billing at a STD clinic in a Medicaid expansion state. Methods The Rhode Island STD Clinic offered HIV/STD screening services at no cost to patients until October 2016, when insurance billing was implemented. Care for uninsured patients was still provided for free. We compared the clinic visits in the preinsurance period with the postinsurance period using t-tests, Poisson regressions, and a logistic regression. Results A total of 5560 patients were seen during the preinsurance (n = 2555) and postinsurance (n = 3005) periods. Compared with the preinsurance period, the postinsurance period had a significantly higher average number of patient visits/month (212.9 vs. 250.4, P = 0.0016), including among patients who were black (36.8 vs. 50.3, P = 0.0029), Hispanic/Latino (50.8 vs. 65.8, P = 0.0018), and insured (106.3 vs. 130.1, P = 0.0025). The growth rate of uninsured (+0.10 vs. +4.11, P = 0.0026) and new patients (−4.28 vs. +1.07, P = 0.0007) also increased between the two periods. New patients whose first visit was before the billing change had greater odds (adjusted odds ratio, 2.68, 95% confidence interval, 2.09–3.44; P < 0.0001) of returning compared with new patients whose first visit was after the billing change. Conclusions Implementation of insurance billing at a publicly funded STD clinic, with free services provided to uninsured individuals, was associated with a modest increase in patient visits and a decline in patients returning for second visits.

Iowa TelePrEP: A Public-Health-Partnered Telehealth Model for Human Immunodeficiency Virus Preexposure Prophylaxis Delivery in a Rural State
imageBackground Access to human immunodeficiency virus (HIV) preexposure prophylaxis (PrEP) is often poor in small urban and rural areas because of stigma and long distances to providers. The Iowa Department of Public Health and The University of Iowa created a regional telehealth program to address these barriers ("Iowa TelePrEP"). We describe initial TelePrEP results and share lessons learned. Methods Iowa Department of Public Health personnel in sexually transmitted infection (STI) clinics, disease intervention specialist and partner services, and HIV testing programs referred clients to pharmacists at University of Iowa. Clients could also self-refer via a website. Pharmacists completed video visits with clients in the community on smartphones and other devices, arranged local laboratory studies, and mailed medications. We performed a retrospective record review to quantify rates of PrEP referral, initiation, retention, guideline-concordant laboratory monitoring, and STI identification and treatment. Results Between February 2017 and October 2018, TelePrEP received 186 referrals (37% from public health) and completed 127 (68%) initial video visits with clients. Median client age was 32; 91% were men who have sex with men. Most clients with video visits (91%) started PrEP. Retention in TelePrEP at 6 months was 61%, and 96% of indicated laboratory monitoring tests were completed. Screening identified 37 STIs (8 syphilis, 10 gonorrhea, 19 chlamydia). Disease intervention specialist and partner services linked all clients with STIs to local treatment within 14 days (80% in 3 days). Conclusions Using widely available technology and infrastructure, public health departments and health care systems can collaborate to develop regional telehealth programs to deliver PrEP in small urban and rural settings.

Men Who Have Sex With Men With Mycoplasma genitalium–Positive Nongonococcal Urethritis Are More Likely to Have Macrolide-Resistant Strains Than Men With Only Female Partners: A Prospective Study
imageBackground Mycoplasma genitalium was previously less common among men who have sex with men (MSM) compared with men with only female partners (MSW) in men with nongonococcal urethritis (NGU) in Sydney, Australia. We aimed to determine the prevalence of M. genitalium and of macrolide-resistant M. genitalium in men with NGU and to compare differences between prevalence and resistance rates between MSM and MSW. Methods We enrolled 588 men with NGU in a prospective study at two urban sexual health services. The ResistancePlus MG assay (SpeeDx, Australia) was used to detect both M. genitalium, and macrolide resistance-associated mutations in first-void urine samples. Demographic, behavioral and clinical data were analyzed to investigate associations with M. genitalium infection or the presence of macrolide resistance. Results Mycoplasma genitalium prevalence was 12.8% (75 of 588) overall and among MSM (12.8% [39 of 306]) and MSW (12.8% [36 of 282]; risk ratio [RR], 1.00; 95% confidence interval [CI], 0.65–1.52). Overall, 70.7% (53 of 75) of M. genitalium strains were macrolide-resistant, with significantly more resistance among MSM (89.7%, 35 of 39) than MSW (50%, 18 of 36) (RR, 1.80; 95% CI, 1.27–2.54; P = 0.001). On multivariate analysis, the presence of M. genitalium macrolide resistance mutations was independently associated with having male sexual partners compared with having only female partners (RR, 1.55; 95% CI, 1.02–2.38; P = 0.042). Conclusions Prevalence of M. genitalium among men with NGU is now similar for MSW and MSM and has increased locally from 5.2% to 12.8% within the last 10 years. Men who have sex with men are significantly more likely than MSW to harbor macrolide-resistant M. genitalium infections. This has treatment implications.

Factors Associated With Increased Syphilis Screening Among People Living With Human Immunodeficiency Virus
imageBackground Antiretroviral therapy effectively reduces the risk of human immunodeficiency virus transmission, but in the context of undetectable equals untransmittable and decreased condom use, rates of syphilis are increasing. In Oregon, syphilis has risen over 20-fold in the past decade, from less than 30 to approximately 600 cases annually during 2016 and 2017. Although many cases are among people living with human immunodeficiency virus infection (PLWH), screening for syphilis among PLWH is often lacking. The objective of this study was to estimate the prevalence of past-year syphilis testing among PLWH in Oregon to identify facility-level and individual-level factors associated with testing. Methods We examined 2015 to 2016 Medical Monitoring Project interview and medical records data in Oregon and conducted supplemental interviews with participants' medical providers. We used generalized mixed effects models to identify factors associated with syphilis screening. Results Sixty-nine percent of Medical Monitoring Project participants had past-year syphilis screening. Patients receiving care from facilities with written sexually transmitted infection screening policies were far more likely to be screened than those receiving care from facilities without written policies (94% vs. 43%, P < 0.001). Participants who identified as male were more likely to have been tested, even after adjusting for facility-level characteristics. Clustering within facility accounted for about 15% of the unexplained variability in the adjusted mixed effects models. Conclusions Written sexually transmitted infection screening policies at medical facilities appear to be an important tool for ensuring syphilis screening occurs as recommended to prevent the continued rise in syphilis.

Excess Cancer Cases and Medical Costs Due to Suboptimal Human Papillomavirus Vaccination Coverage in California
imageBackground Human papillomavirus (HPV) vaccination coverage continues to be at low to moderate levels throughout the United States. HPV infection is linked to multiple types of cancers resulting in high economic and health burden. We aimed to estimate the excess number of cancer cases and associated medical costs due to current HPV vaccination coverage for a 20-year-old birth cohort in California. Methods We estimated the lifetime number of cancer cases caused by vaccine-preventable strains of HPV for a cohort of 20 year-olds in California. We then estimated the excess number of cancer cases in that cohort which would occur due to 2017 HPV vaccination coverage compared with an optimal coverage of 99.5%. By multiplying those excess cases by the average cost of treatment, we determined the excess cost due to current HPV vaccination coverage. Results With current vaccination coverage in California, the 20-year-old cohort is at risk for an excess 1352 cancer cases that could be prevented with a projected optimal vaccination coverage of 99.5%. The excess cost of treatment for those cancer cases would be US $52.2 million. Male oropharyngeal cancer accounts for the greatest projected cost burden US $21.3 million followed by cervical cancer US $16.1 million. Conclusions Increased HPV vaccination coverage in California is needed to reduce economic and health burdens associated with cancers caused by HPV infection.

imageBackground Persistent infection with high-risk types of human papillomavirus (HPV) is the preeminent factor driving the development of cervical cancer. There are large gaps in knowledge about both the role of pregnancy in the natural history of HPV infection and the impact of HPV on pregnancy outcomes. Methods This single-site prospective cohort substudy, nested within an international multisite randomized controlled trial, assessed prevalence, incident cases, and persistence of type-specific HPV infection, and the association between persistence of high-risk HPV infection with pregnancy outcomes among HIV-infected pregnant women in Kenya, including HIV transmission to infants. Type-specific HPV was assessed using a line probe assay in pregnancy and again at 3 months after delivery. HIV status of children was determined using polymerase chain reaction at 6 weeks. Results In total, 84.1% (206/245) of women had a high-risk HPV infection at enrollment. Three quarters (157/206) of these infections persisted postpartum. Persistence of HPV16 and/or HPV18 types was observed in more than half (53.4%; 39/73) of women with this infection at enrollment. Almost two-thirds had an incident high-risk HPV infection postpartum, which was not present in pregnancy (62.5%), most commonly HPV52 (19.0%). After adjustments, no association was detected between persistent high-risk HPV and preterm birth. All mothers of the 7 cases of infant HIV infection had persistent high-risk HPV infection (P = 0.044). Conclusions High levels of high-risk HPV infection and type-specific persistence were documented, heightening the urgency of mass role out of HPV vaccination. The association between HPV persistence and HIV transmission is a novel finding, warranting further study.

Clinical Performance of Human Papillomavirus Testing and Visual Inspection With Acetic Acid in Primary, Combination, and Sequential Cervical Cancer Screening in China
imageBackground World Health Organization guidelines recommend screening with human papillomavirus (HPV) testing followed by either treatment of all HPV-positives, or by visual inspection (VIA) for triage to treatment, citing insufficient evidence to recommend either strategy over the other. Methods We assessed VIA and HPV testing individually, in combination (HPV-VIA cotesting), and as triage models. Three thousand women were screened in Inner Mongolia, China, concurrently with HPV testing and VIA in a real population setting. Screen-positive women underwent colposcopy, and biopsy, if indicated. Accuracy of screening algorithms for cervical intraepithelial neoplasia grade 2 or higher (CIN-2+) was calculated after controlling for verification bias. HPV testing followed by VIA triage for CIN-2+ detection was compared with Hybrid Capture 2 viral loads triage, measured in relative light units/cutoff. Results CIN-2+ prevalence was 1.0%. Corrected sensitivity, false negative rate, and specificity for CIN-2+, respectively, for primary HPV testing were 89.7%, 10.3%, and 83.3%; 44.8%, 55.2%, and 92·3% for VIA; 93.1%, 6.9%, and 80.2% for HPV-VIA cotesting; and 41.4%, 58.6, and 95.4% for HPV with VIA triage scenarios. Using relative light units/cutoff of 5 or greater to triage HPV-positive women had twice the sensitivity as VIA triage, with comparable specificity for CIN-2+. Conclusions When VIA performs relatively poorly and HPV testing is available, adding VIA to sequential (ie, HPV followed by VIA triage) or primary (HPV-VIA cotesting) screening does not significantly improve CIN-2+ detection beyond primary HPV screening alone. Sequential screening (ie, HPV followed by VIA triage) reduces sensitivity too low for population-based screening programs. The HPV viral loads could offer an alternative low-resource country triage strategy.

A primary care pediatrician's guide to assessing problematic interactive media use
imagePurpose of review To review the literature and provide a guide to assessing patients with problematic interactive media use (PIMU). Recent findings 0.3–1.0% of the world population meets criteria for internet gaming disorder (IGD). 26.8–83.3% of adolescents meeting criteria for internet addiction have comorbid attention-deficit/hyperactivity disorder. IGD is associated with increased anxiety and social anxiety/phobias. Group counseling, cognitive behavioral therapy, and sports intervention are associated with significant reductions in internet addiction. Summary With the Diagnostic and Statistical Manual of Mental Disorders-5 inclusion of IGD under 'Conditions for Further Study' and the addition of gaming disorder to International Classification of Diseases (ICD)-11, the idea that PIMU is a mental health disorder gained traction. Although certain populations may be at increased risk, all children and adolescents should be screened for PIMU given now-normal heavy media usage rates. Effective treatment of PIMU starts with identification and management of comorbid mental and behavioral health problems. Depending on their degree of functional impairment, patients may benefit from various forms of psychotherapy with coordinated outpatient management or may warrant higher level of care in one of several established residential treatment programs. Few studies have evaluated pharmacologic approaches to treating PIMU, but some medications targeting comorbid mental and behavioral health conditions improve PIMU-related behaviors.

Adolescent vaccinations: updates for the general practitioner
imagePurpose of review Adolescent providers have a unique opportunity to interface with adolescents during a transformative time period. Optimizing vaccinations may protect teens against preventable but potentially deadly diseases. Healthcare providers must be aware of the evolving vaccination data and up-to-date recommendations for vaccinations. Recent findings In spite of the Center for Disease Control recommendations, there is a gap between the actual and desired vaccination rates of adolescents. Tetanus, diphtheria, and acellular pertussis, meningococcal against ACWY serotypes, and human papillomavirus (HPV) are vaccinations unique to the adolescent period. There has been a marked increase in pertussis cases over the last 2 decades. Either of the meningitis B vaccines may be given to 16–18 year olds and are effective in controlling college outbreaks. Increasing evidence continues to demonstrate the safety and efficacy of the HPV vaccination, although a substantial number of adolescents remain unvaccinated. Fortunately, there are proven strategies to remedy this. Summary Adolescent providers should be aware of the increase in pertussis cases over the past 2 decades and the Category B recommendation for meningococcal B vaccine at 16–18 years, and they should work towards closing the gap between the actual and desired HPV vaccination rates.

An update on the medical consequences of anorexia nervosa
imagePurpose of review The diagnosis of anorexia nervosa is associated with the highest mortality rate of any psychiatric disorder, mainly caused by medical complications. The purpose of this article is to review the common medical consequences of anorexia nervosa focusing on the special considerations related to children and adolescents and recent updates on the pathophysiology of these complications and their prognosis significance. Recent findings The main findings were related to the diagnostic and prognostic value of hypokalaemia, QTc prolongation, hypoglycaemia and orthostatic changes. A new modality to evaluate the heart in anorexia nervosa was explored (2DSTE) as well. Bone mineral density (BMD) loss is one of the few nonreversible consequences of anorexia nervosa. BMD loss does not seem to be significantly related to sex or to cut-off low-weight parameters in teenagers with anorexia nervosa, but rather to the amount of weight loss they have experienced. Brain volume deficits might be another irreversible complication in adolescents with anorexia nervosa. Summary It is crucial for any healthcare provider to be informed about the medical consequences of anorexia nervosa, not only because they can be devastating, but also because they can play an essential role in motivating patients to get treated.

Updates on HIV nonoccupational postexposure prophylaxis
imagePurpose of review Adolescents and young adults continue to contribute to new HIV infections despite improved antiretroviral regimens and HIV preexposure and postexposure prophylaxis (PrEP and PEP). Knowledge about nonoccupational HIV PEP (nPEP) is relevant and important for all pediatricians as adolescents present under a variety of circumstances disclosing past sexual activity. Recent findings nPEP is effective in preventing HIV infection, and newer regimens have been shown to increase compliance amongst users, have less side effects, and lead to less HIV resistance. Yet, research on physician prescription practices shows a lack of knowledge regarding appropriate HIV nPEP medication regimens, dosing, and follow-up recommendations. Updated national guidelines are available to providers who may be unfamiliar with indications and drug regimens for nPEP. Studies also provide different strategies to increase nPEP use and compliance among patients as well as ways to increase provider awareness of appropriate nPEP prescription. Summary Research of HIV nPEP shows that it is effective when used correctly, but there needs to be increased education and awareness to increase provider prescription and patient use as well as institutional changes to help patients complete the full course of medication.

Child and adolescent chronic fatigue syndrome/myalgic encephalomyelitis: where are we now?
imagePurpose of review The current review aims to determine the recent evidence regarding cause, impact, effective treatment and prognosis of children and young people (CYP) affected by chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) at a time when the National Institute for Clinical Excellence guidelines in the United Kingdom are being reviewed and more research is called for worldwide. Recent findings CFS/ME is a debilitating illness with no clear cause. This review describes the heterogeneous clinical picture and the effects on the young person and family. Comorbidities such as mood disorders and pain are discussed including evidence for treatment. The various aetiological hypotheses are discussed and the precipitating factors identified. The evidence base is limited regarding effective treatment for CYP with CFS/ME, particularly the severely affected group. A large trial of online cognitive behavioural therapy with teenagers is being explored in the United Kingdom. The Lightning Process has been shown to be effective when added to medical care. Summary Current evidence is hampered by different diagnostic criteria, the heterogeneous nature of the condition, and limited number of small studies. There is a clear need for more research and larger studies exploring the cause of and most effective treatment for CYP with CFS/ME.

Mindfulness-based interventions for adolescent health
imagePurpose of review Mindfulness, the practice of paying attention to the present moment, purposefully and nonjudgmentally, has been gaining popularity as adjunct treatment for adolescents with a range of physical and mental health problems. Research conducted in adults and emerging research conducted in adolescents has shown that mindfulness-based interventions can improve outcomes in several areas. The purpose of this review is to discuss recent research on the effects of mindfulness and suggest exercises that primary care clinicians can offer to their adolescent patients. Recent findings Research has shown positive effects of mindfulness across several health conditions commonly encountered during adolescence. Mindfulness-based Interventions can reduce symptoms of anxiety and depression. The application of mindfulness can help with the prevention and treatment of binge eating, over-eating, and restrictive eating disorders. In the treatment of substance use disorders, mindfulness can improve emotion regulation and reduce symptoms of withdrawal and craving. Mindfulness can also lead to improvement in overall quality of life for patients suffering from chronic pain. Lastly, mindfulness can be useful for adolescents with ADHD, sleep problems, chronic illness, and stress related to performance sports. Summary Although research in adolescents remains limited, mindfulness holds promise in the treatment of a range of health conditions in adolescents.

Infant skin care: updates and recommendations
imagePurpose of review Neonatal skin acclimates rapidly to dry, aerobic conditions at birth and skin function gradually matures throughout infancy. Gentle skin care practices support the ongoing development and function of newborn skin. This article reviews research updates and current skin care recommendations for full-term infants, premature infants, and infants born with severe cutaneous manifestations of genetic skin disorders. Recent findings Although safe early bathing of full-term infants with environmental controls is possible, delaying the first newborn bath for 12–24 h of life offers benefits of increased parental bonding and breastfeeding success. Swaddled bathing every 4 days is an effective bathing strategy for premature neonates. Among infants with a family history of atopic dermatitis, regular application of bland skin moisturizers reduces their risk of developing the disease. For newborns with erosive or blistering genetic skin conditions, use of specialized wound dressings and emollients promotes wound healing and helps limit skin damage. Environmental control with humidified incubators helps prevent life-threatening hypernatremic dehydration among babies born with collodion membranes; however, affected infants can tolerate breaks outside of the humidifier to promote parent–infant bonding. Summary This article reviews infant skin care recommendations relevant to pediatric practice. Research to further optimize newborn skin care is ongoing, particularly, for the special populations of premature neonates and infants born with severe skin disease.

Diagnosis and management of linear scleroderma in children
imagePurpose of review Linear scleroderma is the most common subtype of localized scleroderma (LoS) in children. It can be associated with extracutaneous manifestations and long-term sequelae. Thus, appropriate diagnosis and management are key to improve the prognosis. In this review, we summarize the most relevant recent publications for the diagnosis, evaluation of disease activity and adequate management of patients with linear scleroderma. Recent findings There are specific clinical features that indicate activity in LoS; dermoscopy and Wood's lamp may be useful. Summarizing, scoring methods seem to provide the most adequate assessment of LoS; but several biomarkers that correlate with activity have been studied: E-selectin and IL-2 receptor, CD34+ dermal dendritic cells and Th/Th1 immunophenotype with decreased T helper (Th2), T regulatory (Tregs), B and natural killer (NK) cells. Recent studies propose hydroxychloroquine monotherapy and tocilizumab as potential therapeutic options. Summary Clinical evaluation, both physical exam and history, is the most important aspect in diagnosing and assessing activity of linear scleroderma. Clinical scoring methods may be most useful for evaluation of activity; eventually, other biomarkers could be relevant in clinical practice. For most patients with linear scleroderma, the first choice of treatment is methotrexate, but physical therapy, plastic surgery and/or orthopedic management are key to improve residual limitations and quality of life.

Narinder P Singh, Jeetinder K Makkar, Vincent Wourms, Andr&#233;s Zorrilla-Vaca, Ronald B Cappellani, Preet M Singh

Indian Journal of Anaesthesia 2019 63(7):520-529

Background and Aims: Post-operative sore throat (POST) is a common undesirable consequence of tracheal intubation. Magnesium, an N-methyl-D-aspartate receptor antagonist, has anti-nociceptive and anti-inflammatory properties, and has been found to be useful in POST prevention in various trials. We conducted this systematic review and meta-analysis to study the efficacy of topical magnesium in preventing POST in adult patients undergoing surgery under general anaesthesia with single lumen tracheal tube. Methods: Comprehensive literature search was performed in PubMed, Google Scholar, EMBASE, Scopus and the Cochrane central registers of controlled trial databases through July, 2018 and data were pooled using fixed effect modelling followed by random-effect methods (after assessing heterogeneity with fixed modelling). The primary outcome was the incidence of POST at 24 h after surgery/extubation. Comparative results were deliberated as pooled mean difference for continuous variables and Mantel&#8211;Haenszel (MH) odds ratio for dichotomous variables. Statistical analysis was done using Comprehensive Meta-Analysis-Version 3 (Biostat Inc., USA). Results: Seven trials involving 726 study participants were included in the final analysis. Incidence of POST at 24 hours was significantly lower in magnesium group (26/363) in comparison to active and non-active control group (89/363); P &#61; 0.00- RR 0.22 (95&#37;CI &#61; 0.12-0.39, I2 &#61; 0&#37;). No significant adverse events were reported with the use of topical magnesium. Conclusion: Prophylactic use of topical magnesium before the induction of general anaesthesia seems to be an effective measure to decrease the incidence of POST. 


Is COMBIPECS the answer to perioperative analgesia for breast surgery? A double blinded randomized controlled trial
Rakhi Khemka, Arunangshu Chakrborty, Sanjit Agrawal, Rosina Ahmed

Indian Journal of Anaesthesia 2019 63(7):530-536

Background and Aims: Pecs block and its variations provides perioperative analgesia, reduce PONV and other opioid related side effects. We hypothesized that COMIBPES block in addition to general anaesthesia will provide better postoperative analgesia when compared to general anaesthesia alone in breast cancer surgery patients. Methods: After obtaining permission from the institutional review board and registering the trial with Clinical Trials Registry of India (CTRI), we conducted a double blinded randomized controlled trial of 100 patients posted for elective breast surgery with axillary dissection. Patients were divided into two groups, P (Pecs block) and C (control). Intraoperative analgesia, postoperative analgesia, postoperative nausea vomiting (PONV) and shoulder mobility on first postoperative day (POD1) were noted. Primary outcomes were the pain scores measured by visual analog scale (VAS) and cumulative intravenous morphine consumption from patient controlled analgesia (PCA) pump at measurement intervals of 0, 1, 4, 8, 12 and 24 hours postoperatively. Results: Intraoperatively, Group P patients did not require any additional analgesia, whereas all the patients in Group C required additional intraoperative morphine (mean, SD: 5.12, 2.63 mg, compared to nil in group P, P< 0.01). COMBIPECS block group had lower pain scores and PCA morphine requirements, less PONV and better shoulder mobility on POD1. Conclusion: COMBIPECS block is a valuable addition to general anaesthesia for breast cancer surgery as it reduces pain and PONV while allowing better postoperative shoulder mobility. 


A study to evaluate effect of PEEP and end-tidal carbon dioxide on optic nerve sheath diameter
Renu Bala, Rajesh Kumar, Jyoti Sharma

Indian Journal of Anaesthesia 2019 63(7):537-543

Background and Aims: PEEP is commonly used to improve postoperative respiratory outcomes in surgical and ICU patients. It is thought to increase ICP by impending CSF outflow and cerebral venous drainage. Hyperventilation is used to decrease ICP in patients having intracranial hypertension. We investigated the effect of various levels of PEEP and EtCO2 on ONSD as an indirect predictor of ICP in patients undergoing surgery under GA. Methods: After induction, different levels of PEEP and EtCO2 were applied to 50 patients. Sonographic ONSD was measured 5 minutes after stabilization of each new setting. Haemodynamic parameters like pulse, SpO2, BP were also recorded. Quantitative variables were expressed as Mean &#177; SD and compared across between follow-ups using paired t-test. Qualitative variables were expressed in number and percentage. Results: Baseline ONSD was 0.44 &#177; 0.06 cm. It increased significantly to 0.45 &#177; 0.07 cm, 0.47 &#177; 0.07 cm and 0.49 &#177; 0.07 cm after applying PEEP of 8, 12 and 15 cm H2O PEEP, respectively. It significantly decreased to 0.42 &#177; 0.06 cm, 0.41 &#177; 0.06 cm and 0.40 &#177; 0.06 cm after hyperventilation, EtCO2 range 35&#8211;37, 32&#8211;34 and 29&#8211;31 mm Hg. Results were statistically significant but clinically not significant. Conclusion: We conclude that there are acute and dynamic alterations in ONSD in response to hyperventilation and presence of PEEP in anaesthetised patients. Ocular sonography may be used as a reliable indicator of acute variations in ICP.

Dinesh Kumar, Satinder Gombar, Vanita Ahuja, Arvind Malhotra, Shruti Gupta

Indian Journal of Anaesthesia 2019 63(7):544-550

Background and Aims: Airway management in patients with cervical spine pathology is challenging. The aim of the study was to evaluate GlideScope (GVL) and D blade of C-MAC (CMAC-D) using manual inline axial stabilisation (MIAS) for tracheal intubation in patients with cervical spine injury/pathology. Methods: This is a randomised, single-blind, hospital-based study. After obtaining informed consent, 54 patients with cervical spine pathology/injury were grouped into GVL group or CMAC-D group, (n &#61; 27 each) based on computer-generated random number table. Preoperative airway difficulty score (ADS) was calculated. The primary outcome of the study was intubation difficulty score (IDS) and the secondary outcomes included total time taken to secure airway, failure to intubate, haemodynamic parameters and adverse events. Data was represented in the form of number (&#37;) or mean and standard deviation and median and interquartile range as appropriate. Chi square test was used for analysing IDS. Results: The mean &#177; SD of IDS of the CMAC-D and GVL groups were 0.04 &#177; 0.2 (0.04&#8211;0.11) and 0.19 &#177; 0.40 (0.03&#8211;0.34), respectively, (P value &#61; 0.096). The number (&#37;) of patients with IDS &#62; 0 was 1 (3.7) in CMAC-D and 5 (18.5) in GVL group, (P value &#61; 0.192). Demographic data, ADS, Cormack&#8211;Lehane grading, success rate, time of tracheal intubation, type of surgeries, haemodynamic parameters and post-operative complications were similar in both the groups. Conclusion: Both GVL and CMAC-D with MIAS are equally efficacious in tracheal intubation in cervical spine injury/pathology patients without other difficult airway management criteria. 


Doppler resistive index to reflect risk of acute kidney injury after major abdominal surgery: A prospective observational trial
Kavitha Muthukrishnan, Satyen Parida, S Deepak Barathi, Ashok Shankar Badhe, Sandeep Kumar Mishra

Indian Journal of Anaesthesia 2019 63(7):551-557

Background and Aims: Doppler renal resistive index (RI) has been studied to find its association with postoperative acute kidney injury (AKI). This study was conducted to evaluate the usefulness of preoperative RI, postoperative RI and RI variation before and after surgery expressed as a percentage (&#37; RI) for early AKI detection in major abdominal surgery. Methods: This was a single-centre, prospective observational trial performed in the critical care unit of an academic hospital. Eligible patients posted for major abdominal surgery under general anaesthesia using intraperitoneal approach with at least two predefined risk factors for AKI were included in the study. Renal RI was measured preoperatively and on postoperative day zero. Statistical comparisons were performed for various parameters between the AKI and the non-AKI groups. Pre- and postoperative RI receiver operating characteristics (ROC) curves were drawn and areas under the curves computed. Positive and negative predictive values, sensitivity, specificity and positive and negative likelihood ratios were calculated. Results: A total of 69 subjects were enrolled, of which 14 developed AKI in the postoperative period. The mean resistive indices measured were 0.65 &#177; 0.09 and 0.74 &#177; 0.09 in the pre- and postoperative periods, respectively. The area under the ROC curve in the postoperative RI was 0.732 with 95&#37; confidence intervals of 0.592&#8211;0.871. This most accurate cut-off value to detect postoperative AKI with sensitivity 57.1&#37; and specificity of 85.5&#37; was 0.77. Conclusion: Postoperative RI can detect early AKI after major abdominal surgery. 


A new second-generation supraglottic airway device (Ambu® AuraGain•) versus intubating laryngeal mask airway as conduits for blind intubation – A prospective, randomised trial
K Sudheesh, GM Chethana, H Chaithali, SS Nethra, D Devikarani, G Shwetha

Indian Journal of Anaesthesia 2019 63(7):558-564

Background and Aims: The Ambu&#174; AuraGain&#8226; is a new single-use supraglottic airway device with gastric channel, designed to facilitate intubation. The study aimed to assess the success rates of proper placement and intubation using Ambu&#174; AuraGain&#8226; compared with intubating laryngeal mask airway (ILMA). Methods: One hundred and twenty patients (18&#8211;60 years) were enrolled into this prospective, randomised, comparative study. After inducing general anaesthesia, appropriate size ILMA (group I)/Ambu&#174; AuraGain&#8226; (group A) was placed as per the manufacturer&#39;s recommendations and correct placement was confirmed. Appropriate size endotracheal tube was passed through the device. The success rate of insertion and intubation, number of attempts, Cormack&#8211;Lehane grading before insertion and haemodynamics were recorded. Data were analysed using Mantel&#8211;Haenszel Chi-square test, Student&#39;s t-test and Fisher&#39;s exact test. Results: Demographic and airway parameters were uniformly distributed in both the groups. The success rate for insertion was 100&#37; in both devices. The success rate for intubation was 96.6&#37; (58/60) in group I and 36.6&#37; in group A (P < 0.001). In group I, patients with mean thyromental distance &#62;7.62 &#177; 0.75 cm had higher successful intubation compared with patients with mean thyromental distance &#60;5.25 &#177; 0.35 cm (P &#61; 0.014). Cormack&#8211;Lehane grading did not correlate with intubation attempts or success rate in group I (P &#61; 0.45), whereas in group A the rate of successful blind intubation with Cormack&#8211;Lehane grade 1 was 50&#37; (19/38). Conclusion: Both devices have 100&#37; insertion success, though Ambu&#174; AuraGain&#8226; has lower success rate for facilitating intubation compared with ILMA.

Aarti Baghele, Nandini Dave, Raylene Dias, Harick Shah

Indian Journal of Anaesthesia 2019 63(7):565-570

Background and Aims: There have been various methods tested for reducing preoperative anxiety in children, but very limited literature is available in the Indian scenario. Our aim was to analyse the effect of an informative video about the anaesthetic technique on preoperative anxiety in children. Methods: In all, 94 children were randomly allotted into two groups. Children in the study group were shown a peer modelling video depicting induction of general anaesthesia and recovery during the preanaesthetic check (PAC). Patients in the control group were given only verbal information during PAC. Anxiety was assessed on visual analog scale (VAS) for anxiety at two times. Baseline VAS score was recorded during PAC and preoperative VAS score was assessed prior to induction of anaesthesia. The VAS score was represented as median value. Data were analysed using the Mann&#8211;Whitney U-test for ordinal data and skewed quantitative data. Categorical data was analysed by using Chi-square test and t-test was applied for quantitative data. The significance threshold of P value was set at &#60;0.05. Results: The median (interquartile range) preoperative VAS score was significantly lower in the study group [1 (0&#8211;1.3)] when compared with the control group [5 (3&#8211;5)] (P < 0.001). The mean preoperative pulse rate, mean preoperative systolic blood pressure and mean preoperative diastolic blood pressure were significantly lower in the study group when compared with the control group (P < 0.001). Conclusion: Multimedia information in the form of a peer modelling video helped reduce preoperative anxiety in children between 7 and 12 years of age. 


Retraction of papers authored by Yuhji Saitoh – Beyond the Fujii phenomenon
Priyam Saikia, Bandana Thakuria

Indian Journal of Anaesthesia 2019 63(7):571-584

Background and Aims: Various aspects of retracted articles authored by Yoshitaka Fujii and their retraction notices have been examined. Yuhji Saitoh has coauthored many articles with Yoshitaka Fujii which were subsequently retracted. Japanese Society of Anesthesiology (JSA) recommends retraction of various articles by Yuhji Saitoh, but various attributes of those and their retraction notices have not been examined. Methods: A list of retracted articles was retrieved from PubMed, Retraction Watch Database and relevant journals. Their retraction notices were obtained from the journal&#39;s webpage. Predefined characteristics of the retracted articles and their retraction notices were evaluated against those proposed by Committee on Publication Ethics (COPE). Results: Fifteen such articles were retracted. Two of them were not identified as retracted in the journal webpage. Half of the papers mentioned by JSA are yet to be retracted. Among those retracted, only 13.3&#37; retraction notices were in line with the guidelines published by the COPE. Two retracted articles are yet to be flagged as retracted in PubMed. The median (interquartile range) time required for retraction from the date of declaration of being eligible for retraction is 14 (3) months. Data were analysed with Microsoft Excel&#8482; (2007). Conclusion: Even after more than 1 year of recommendation, many articles containing evidence of scientific misconduct are yet to be retracted. Among those retracted, the relevant authority failed to follow the prevalent and well-regarded standards of ethics in scholarly publication.
