Substance use disorders are among the most prevalent and emergent public health problems in India. The treatment of individuals with these disorders is associated with many ethical dilemmas. Due to the pervasiveness of substance use disorders, the majority of mental health professionals working in the area of addiction medicine face several ethical dilemmas. When discussing substance use disorders, it must be borne in mind that there are important differences between India and the western countries in terms of the social and cultural aspects, as well as the legislative framework and healthcare delivery system...

The problem of determining the contours of objects in nuclear medicine images has been studied extensively in the past, however most of the analysis has focused on a single object as opposed to multiple objects. The aim of this work is to develop an automated method for determining the contour of multiple objects in positron emission tomography (PET) and single photon emission computed tomography (SPECT) filtered backprojection (FBP) reconstructed images. These contours can be used for computing body edges for attenuation correction in PET and SPECT, as well as for eliminating streak artifacts outside the objects, which could be useful in compressive sensing reconstruction...

David O Arnar, Runolfur Palsson
In the past decade, large scale genotyping has led to discoveries of numerous sequence variants that confer increased risk of many common complex diseases. Interestingly, a substantial proportion of pioneering genetic work has originated from the small nation of Iceland and has been facilitated by an extensive genealogy database. We provide examples of relevant observations made so far in several major disease categories central to internal medicine practice. Some of these findings offer new mechanistic clues into the pathophysiology of common disorders and may suggest novel approaches in diagnosis and drug therapy...

BACKGROUND: Ficus carica Linn. (Fc), common fig, has been traditionally used for many metabolic, cardiovasculary, respiratory, gastrointestinal, and skin disorders. Several studies were performed showing its anti-inflammatory, anti-angiogenic, anticancerogenic, and tissue-protective effects. In all of those studies, the positive effects of Fc were concluded as the result of its antioxidant and anti-inflammatory features due to the polyphenols it contains. AIMS: To study the phenolic compounds of Fc extract and to investigate the molecular basis of anti-inflammatory, anti-angiogenic, antimitotic, and anti-androgenic effects of Fc leaf extract in vitro...

The standardised randomised clinical trial (RCT) has been exceedingly popular in medical research, economics, and practical policy making. Recently, RCTs have faced criticism. First, it has been argued by John Worrall that we cannot be certain that our sample is not atypical with regard to possible confounding factors. I will argue that at least in the case of medical research, we know enough about the relevant causal mechanisms to be justified to ignore a number of factors we have good reason not to expect to be disruptive...

Contrast-induced nephropathy (CIN) has become the third-leading cause of hospital-acquired acute renal injury. Although alprostadil has been proposed as an effective preventative measure, this conclusion remains inconsistent. Thus, we performed a meta-analysis of the published studies on this topic to evaluate the preventative effect of alprostadil on CIN. Databases, including PubMed, the Web of Science, Cochrane Library, Wanfang, the China Biological Medicine Database (SinoMed) and the China National Knowledge Infrastructure (CNKI) were systematically searched...

India accounts for one-fourth of the global tuberculosis (TB) burden. The National TB Program was started in 1962. Over a period of time, some lacunae such as poor case detection rate and incomplete treatment were observed. Later, the government formulated the Revised National Tuberculosis Control Program (RNTCP), which achieved a case detection rate of 70% and a cure rate of 85%. Still, the problem of relapse and defaulter cases persists. In 2014, 6% defaulter cases were reported from India. RNTCP has also focused on microlevel aspects, that is, newer diagnostics such as GenXpert, line probe assay and medicines such as bedaquiline for drug-resistant TB...

Daniel J Green, Kurt J Smith
Physical activity has profound impacts on the vasculature in humans. Acute exercise induces immediate changes in artery function, whereas repeated episodic bouts of exercise induce chronic functional adaptation and, ultimately, structural arterial remodeling. The nature of these changes in function and structure are dependent on the characteristics of the training load and may be modulated by other factors such as exercise-induced inflammation and oxidative stress. The clinical implications of these physiological adaptations are profound...

Membrane Lipid Replacement is the use of functional, oral supplements containing mixtures of cell membrane glycerolphospholipids, plus fructooligosaccharides (for protection against oxidative, bile acid and enzymatic damage) and antioxidants, in order to safely replace damaged, oxidized, membrane phospholipids and restore membrane, organelle, cellular and organ function. Defects in cellular and intracellular membranes are characteristic of all chronic medical conditions, including cancer, and normal processes, such as aging...

BACKGROUND AND AIMS: Precision, personalized or stratified medicine, which promises to deliver the right treatment to the right patient, is a topic of international interest in both the lay press and the scientific literature. A key aspect of precision medicine is the identification of biomarkers that predict the response to medications (i.e. pharmacogenetics). We examined why, despite the great strides that have been made in biomarker identification in many areas of medicine, only in oncology has there been substantial progress in their clinical implementation...

Introduction Drowning with submersion over 10 minutes is associated with a high mortality. Here, we present a case, in which a good neurological outcome was achieved after interdisciplinary, intensive care therapy despite submersion of 20 minutes followed by 16 hours of hypoxia. History A 19 year old man drowned in fresh-water. After 20 minutes submersion he was localized and salvaged from 8 meters depth and primarily resuscitated successfully after 10 minutes. Within the next hour, there condition worsened by respiratory deterioration due to a massive capillary leak syndrome in addition to a disseminated intravascular coagulation...

Objectives: To determine if the large and highly reproducible inter-individual differences in arousal intensity and heart rate response to arousal (ΔHR) during non-REM sleep are heritable. Methods: Polysomnograms of 55 monozygotic (14 male and 41 female pairs) and 36 dizygotic (15 male and 21 female pairs) same-sex twin pairs were analyzed. Arousals were scored using the 2012 American Academy of Sleep Medicine criteria. Arousal intensity was scaled (between 0 and 9) using an automatic algorithm based on the change in EEG time and frequency characteristics...

Traditionally, the efficacy of cancer treatment in patients with advance or metastatic disease in clinical studies has been studied using overall survival (OS) and more recently tumor-based endpoints such as progression-free survival, measurements of response to treatment. However, these seem not to be the relevant clinical endpoints in current situation if such endpoints were no validated as surrogate of OS to demonstrate the clinical efficacy. Appropriate, meaningful, primary patient-oriented and patient-reported endpoints that adequately measure the effects of new therapeutic interventions are then crucial for the advancement of clinical research in metastatic colorectal cancer to complement the results of tumor-based endpoints...
