Sudip Bhattacharya, Amarjeet Singh
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...

Synthetic musk compounds are widely used in the formulation of several cosmetics, personal care and household products. Due to their massive and widespread use, together with some health concerns, they are considered emerging pollutants and have been detected in different environmental compartments. This study focused on the evaluation of the concentration of synthetic musks (five nitro, five polycyclic and one macrocyclic musks) in beach sands, from Oporto coastal area (Portugal), contributing to the enhancement of the knowledge of levels, trends and behaviour of these compounds in this particular matrix...

Carynelisa Haspel, Masada Tzabari
In this study, we performed a series of sensitivity tests in order to elucidate the convergence tendency of the scattering order formulation (SOF) of the discrete dipole approximation (DDA). Using both the original formulation of the SOF and a new marching SOF, the progression of orders of scattering marches, along with the propagation of the incident plane wave through the scatterer, allow dipoles that come into steady-state oscillation with the incident wave earlier to more quickly advance to the next order of scattering that is local to them...

For decades, panretinal photocoagulation (PRP) has been the standard of care for the treatment of proliferative diabetic retinopathy (PDR). The relatively recent advent of anti-vascular endothelial growth factor (VEGF) formulations for intravitreal injection has provided a fresh perspective on PDR treatment, especially in eyes with concurrent diabetic macular edema (DME). The anti-VEGF agent ranibizumab has demonstrated a potentially protective effect on eyes with DME in terms of progression to PDR in the RIDE/RISE trials, as has aflibercept in the VIVID/VISTA trials...

The development of engineered tissues has progressed over the past 20 years from in vitro characterization to in vivo implementation. For musculoskeletal tissue engineering in particular, the emphasis of many of these studies was to select conditions that maximized functional and compositional gains in vitro. However, the transition from the favorable in vitro culture environment to a less favorable in vivo environment has proven difficult, and, in many cases, engineered tissues do not retain their preimplantation phenotype after even short periods in vivo...

Considerable effort has been devoted to the estimation of species interaction strengths. This effort has focused primarily on statistical significance testing and obtaining point estimates of parameters that contribute to interaction strength magnitudes, leaving the characterization of uncertainty associated with those estimates unconsidered. We consider a means of characterizing the uncertainty of a generalist predator's interaction strengths by formulating an observational method for estimating a predator's prey-specific per capita attack rates as a Bayesian statistical model...

Potentially inappropriate prescribing is a common problem, especially in elderly care. To tackle this problem, Irish medical experts have developed a list of criteria when medication should be added or omitted based upon the patient's physical condition and medication use, known as the STOPP and START criteria. The STOPP and START criteria have been formulated to identify the prescribing of potentially inappropriate medicines (PIMs) and potential prescribing omissions (PPOs). One of the most common problems of inappropriate prescribing is gastro-intestinal track bleedings...

The anatomic and physiologic changes in the gastrointestinal (GI) tract after bariatric surgery may significantly affect the pharmacokinetics of medications taken by the patients for various reasons. Unfortunately, there is little information regarding changes in drug absorption after bariatric surgeries, limiting the ability of medical professionals to produce clear recommendations on what changes should be made to the formulations and dosing regimens of drugs after bariatric surgery. In this article, we report and analyze a case of 52-year-old male patient with morbid obesity and attention-deficit/hyperactivity disorder (ADHD) who experienced lack of methylphenidate efficacy after Roux en-Y gastric bypass (RYGB), which was eventually resolved by using the transdermal patch instead of an oral product...

BACKGROUND: Substantial reductions in the burden of malaria have been documented in parts of sub-Saharan Africa, with elimination strategies and goals being formulated in some regions. Within this context, understanding the epidemiology of low-level malaria transmission is crucial to achieving and sustaining elimination. A 24 single-nucleotide-polymorphism Plasmodium falciparum molecular barcode was used to characterize parasite populations from infected individuals identified through passive and active case detection in an area approaching malaria elimination in southern Zambia...

INTRODUCTION: In France, 26 regional pediatric palliative care teams (ERRSPP) were created between 2008 and 2012. We conducted the first prospective French study to describe the main specifications of the initial contact with an ERRSPP and to analyze the responses given. DESIGN AND METHODS: All the requests for interventions on the part of the ERRSPP were collected between September 2013 and September 2014. We prospectively completed a questionnaire on the patient's clinical and demographic data (age, sex, disease), details regarding the request (type of applicant, unit's specialty, request pattern), and the answers provided (interval between diagnosis and request, duration of care by ERRSPP, death, changes compared to the initial request)...

Transfer entropy has been used to quantify the directed flow of information between source and target variables in many complex systems. While transfer entropy was originally formulated in discrete time, in this paper we provide a framework for considering transfer entropy in continuous time systems, based on Radon-Nikodym derivatives between measures of complete path realizations. To describe the information dynamics of individual path realizations, we introduce the pathwise transfer entropy, the expectation of which is the transfer entropy accumulated over a finite time interval...

INTRODUCTION: Dehiscence of a mitral valve annuloplasty ring is a rare occurrence that often manifests as mitral regurgitation and heart failure. We present a case of mitral ring dehiscence which was initially unrecognized by standard 2-dimensional transthoracic echocardiography (2D TTE); and 2-dimensional transesophageal echocardiography (2D TEE);. CASE: A 65-year-old woman was referred to Cardiology clinic for evaluation of dyspnea. Her history included tobacco abuse, atrial fibrillation status post pulmonary vein isolation, nonischemic cardiomyopathy, and prior mitral valve repair with annuloplasty ring for rheumatic valvular disease...

Yejun Wang, Waruna D Kulatilaka
In most coherent spectroscopic methods used in gas-phase laser diagnostics, multiple laser beams are focused and crossed at a specific location in space to form the probe region. The desired signal is then generated as a result of nonlinear interactions between the beams in this overlapped region. When such diagnostic schemes are implemented in practical devices having turbulent reacting flow fields with refractive index gradients, the resulting beam steering can give rise to large measurement uncertainties...

The effects of inorganic salts and organic hydrocarbons on membrane fouling are often investigated independently. However, in many cases, these foulants are commonly found together, and such mixtures are rarely the subject of fouling studies. In this study, crude oil-in-water emulsions were formulated at three different added NaCl concentrations, 0, 10(-3) and 10(-1) M. Surface properties, such as surface tension and surface charge, of these emulsions and a poly(vinylidene fluoride) (PVDF) microfiltration (MF) membrane were characterized...

BACKGROUND: Mass drug administration (MDA) of praziquantel has been the intervention of choice against schistosomiasis but with limited success in interrupting the transmission. The development of anti-Schistosoma vaccines is underway. Our objective is to quantify the population-level impact of anti-Schistosoma vaccines when administered alone and in combination with mass drug administration (MDA) and determine factors in vaccine design and public health implementation that optimize vaccination role in schistosomiasis control and elimination...

Alzheimer's disease treatment is still an open problem. The diversity of symptoms, the alterations in common pathophysiology, the existence of asymptomatic cases, the different types of sporadic and familial Alzheimer's and their relevance with other types of dementia and comorbidities, have already created a myth-fear against the leading disease of the twenty first century. Many failed latest clinical trials and novel medications have revealed the early diagnosis as the most critical treatment solution, even though scientists tested the amyloid hypothesis and few related drugs...
