Background Active case finding is a top priority for the global control of tuberculosis, but robust evidence for its effectiveness in high-prevalence settings is lacking. We sought to evaluate the effectiveness of household-contact investigation, as compared with standard, passive measures alone, in Vietnam. Methods We performed a cluster-randomized, controlled trial at clinics in 70 districts (local government areas with an average population of approximately 500,000 in urban areas and 100,000 in rural areas) in eight provinces of Vietnam...

Background: While evidence is increasingly consistent with a positive association between periodontitis and cancer risk, most studies have relied on self-reported periodontitis. In this study, we prospectively evaluated the association of periodontal disease severity with cancer risk in black and white older adults in a cohort study that included a dental examination. Methods: Included were 7466 participants in the Atherosclerosis Risk in Communities study cohort who at visit 4 (1996-1998) reported being edentulous or underwent the dental examination...

Phase 1 healthy volunteer clinical trials-which financially compensate subjects in tests of drug toxicity levels and side effects-appear to place pressure on each joint of the moral framework justifying research. In this article, we review concerns about phase 1 trials as they have been framed in the bioethics literature, including undue inducement and coercion, unjust exploitation, and worries about compromised data validity. We then revisit these concerns in light of the lived experiences of serial participants who are income-dependent on phase 1 trials...

Objective: The experimenter expectancy effect confound remains largely unexplored in neuropsychological research and has never been investigated among cannabis users. This study investigated whether examiner expectancies of cannabis user status affected examinees' neuropsychological performance. Method: Participants included 41 cannabis users and 20 non-users. Before testing, examiners who were blind to participant user status privately rated whether they believed the examinee was a cannabis user or non-user...

The posterior visual pathway is commonly affected by multiple sclerosis (MS) pathology that results in measurable clinical and electrophysiological impairment. Due to its highly structured retinotopic mapping, the visual pathway represents an ideal substrate for investigating patho-mechanisms in MS. Therefore, a reliable and robust imaging segmentation method for in-vivo delineation of the optic radiations (OR) is needed. However, diffusion-based tractography approaches, which are typically used for OR segmentation are confounded by the presence of focal white matter lesions...

BACKGROUND: Hutchinson-Gilford progeria syndrome (HGPS) is an ultra-rare, fatal, segmental premature aging syndrome caused by the aberrant lamin A protein, progerin. The protein farnesyltransferase inhibitor, lonafarnib, ameliorates some aspects of cardiovascular and bone disease. STUDY DESIGN: We performed a prospective longitudinal survey of plasma proteins in 24 children with HGPS (an estimated 10% of the world's population at the time) at baseline and on lonafarnib therapy, compared to age and gender-matched controls using a multi-analyte, microsphere-based immune-fluorescent assay...

BACKGROUND: A long-standing relationship between orthopaedic surgeons and industry has made financial conflicts of interest a concerning issue. Research supports that financial conflicts of interest can influence both medical research and clinical practice. Financial conflicts of interest may also influence clinical practice guideline recommendations and their corresponding appropriate use criteria. Because of the influential nature of these guidelines, it is imperative that care be taken to minimize bias during guideline development...

BACKGROUND: Potential sex bias has been shown in general surgery basic science and translational research, with unequal representation of male and female specimens. Because basic science research forms the foundation for clinical studies on which patient care is based, it is important that this research equally consider both sexes. The purpose of this study was to determine if potential sex bias exists in the basic science and translational orthopaedic literature. METHODS: A systematic review was conducted of all articles published in 2014 in The Journal of Bone & Joint Surgery, Clinical Orthopaedics and Related Research, The Bone & Joint Journal, and the Journal of Orthopaedic Research (JOR)...

Fasting for cholesterol measurement has long been the accepted convention. Recent research expounded in clinical guidelines indicates that nonfasting cholesterol measurements predict outcomes at least as well as fasting cholesterol measurements. In most-but not all-clinical scenarios, fasting is not necessary. This article provides clinical recommendations based on the literature.

The increased prevalence of myopia in the United States and other regions of the world, and the sight-threatening problems associated with higher levels of myopia have led to great interest in research designed to reduce these rates. As most of the progression of myopia occurs in childhood, these investigations have been directed toward slowing the progression of myopia in children. Treatments described to potentially slow the progression of myopia have included pharmacological interventions, multifocal spectacles, and multifocal correction created by contact lenses...

PURPOSE: To evaluate the presence of atopy in patients with ocular cicatricial pemphigoid (OCP). METHOD: Patient encounters between August 2005 and November 2016 at the Massachusetts Eye Research and Surgery Institute (MERSI) were searched to identify those with biopsy-proven OCP who had concurrent evidence of atopy. RESULTS: There were 230 patients with biopsy-proven OCP. Thirty-three of them were found to have clinical symptoms of atopy (asthma, hay fever, and eczema) and of these, 23 had evidence of atopy in their conjunctival biopsy specimens...

BACKGROUND: The introduction of complex antiretroviral therapy has resulted in signifi cant decrease in the mortality rate of HIV positive patients, but it still remains unacceptably high, especially in some groups of patients. AIM: To investigate the death rate in patients with HIV/AIDS, lethality and mortality in co-infection, and the most common causes and predictors of fatal outcome, focused on early diagnosis and appropriate therapy. MATERIALS AND METHODS: The study included 53 deceased patients with HIV/AIDS, monitored at the Clinic of Infectious Diseases in St George University Hospital, Plovdiv between 01...

REVIEW
Haroon Khan, Surriya Amin, Seema Patel
Current therapies in clinical practice face strong criticism regarding their efficacy, and side effects, which forced the neuro-researchers to discover novel agents with different mechanistic insights. Glycosides are naturally-occurring plant secondary metabolites with significant medicinal potential and clinical scope as antidepressant. The aim of this review is to focus on the antidepressant effects of glycosides in preclinical studies, with an emphasis on the possible mechanisms. The literature search revealed that only a few phytoglycosides have been evaluated for their relevance in depression alleviation...

The magnetic properties and safety of dextran-coated superparamagnetic iron oxide nanoparticles (SPIONs) have facilitated their clinical use as MRI contrast agents and stimulated research on applications for SPIONs in particle imaging and magnetic hyperthermia. The wider clinical potential of SPIONs, however, has been limited by their rapid removal from circulation via the reticuloendothelial system (RES). We explored the possibility of extending SPION circulatory time using fucoidan, a seaweed-derived food supplement, to inhibit RES uptake...

Sepsis is characterised by organ dysfunction resulting from infection, with no reliable single objective test and current diagnosis based on clinical features and results of investigations. In the ED, investigations may be conducted to diagnose infection as the cause of the presenting illness, identify the source, distinguish sepsis from uncomplicated infection (i.e. without organ dysfunction) and/ or risk stratification. Appropriate sample collection for microbiological testing remains key for subsequent confirmation of diagnosis and rationalisation of antimicrobials...

Antisense transcription is a widespread phenomenon in mammalian genomes, leading to production of RNAs molecules referred to as natural antisense transcripts (NATs). NATs apply diverse transcriptional and post-transcriptional regulatory mechanisms to carry out a wide variety of biological roles that are important for the normal functioning of living cells, but their dysfunctions can be associated with human diseases. In this review, we attempt to provide a molecular basis for the involvement of NATs in the etiology of human disorders such as cancers and neurodegenerative and cardiovascular diseases...

Robust plate based antibody glycan analysis platforms are urgently needed for biopharmaceutical development and manufacturing as well as for clinical biomarker research. A 96-well plate based workflow has been developed to analyze both intact IgG antibodies and released N-glycans using an Orbitrap Fusion Mass Spectrometer and an LC/MS method on the Waters UNIFI platform. Here we describe such a workflow including protein A purification, PNGaseF digestion, 2-AB labeling and SPE clean-up. The measured IgG glycan profile is consistent with that obtained from non-plate based method and commercial kit and has the advantage of less hands-on time...

REVIEW
Janet Treasure, Monica Leslie, Rayane Chami, Fernando Fernández-Aranda
Explanatory models for eating disorders have changed over time to account for changing clinical presentations. The transdiagnostic model evolved from the maintenance model, which provided the framework for cognitive behavioural therapy for bulimia nervosa. However, for many individuals (especially those at the extreme ends of the weight spectrum), this account does not fully fit. New evidence generated from research framed within the food addiction hypothesis is synthesized here into a model that can explain recurrent binge eating behaviour...
