Pregnant women with diabetes may have underlying beta cell dysfunction due to mutations/rare variants in genes associated with Maturity Onset Diabetes of the Young (MODY). MODY gene screening would reveal those women genetically predisposed and previously unrecognized with a monogenic form of diabetes for further clinical management, family screening and genetic counselling. However, there are minimal data available on MODY gene variants in pregnant women with diabetes from India. In this study, utilizing the Next generation sequencing (NGS) based protocol fifty subjects were screened for variants in a panel of thirteen MODY genes...

Methylenedioxypyrovalerone (MDPV) is a synthetic, cathinone-derivative, central nervous system stimulant taken to produce a cocaine- or methamphetamine-like high. Physical manifestations include tachycardia, hypertension, arrhythmias, hyperthermia, sweating, rhabdomyolysis, hyperkalaemia, disseminated intravascular coagulation, oliguria and seizures. We report a patient who presented with severe metabolic acidosis, multi-organ dysfunction, rhabdomyolysis, hyperkalaemia and seizures. This case highlights that even though a urine drug screen for routine psychostimulant drugs is negative, clinicians need to be vigilant about the adverse effects of MDPV as a possible cause of multi-organ dysfunction...

BACKGROUND: Clinical relevance of nontuberculous mycobacteria (NTM) is increasing worldwide including in Saudi Arabia. A high species diversity of NTM's has been noticed in a recent study. However, the identification in diagnostic laboratories is mostly limited to common species. The impact of NTM species diversity on clinical outcome is so far neglected in most of the clinical settings. METHODOLOGY/PRINCIPAL FINDINGS: During April 2014 to September 2015, a nationwide collection of suspected NTM clinical isolates with clinical and demographical data were carried out...

A recent meta-analysis demonstrated that statin therapy was associated with a risk of diabetes. The present study investigated whether the relative reduction in low-density lipoprotein cholesterol (LDL-c) was a good indicator of the risk of new-onset diabetes. We searched the PubMed, Embase, Cochrane Central Register, Lilacs, Food and Drug Administration, and European Medicines Agency databases for randomized controlled trials of statins. Fourteen trials were included in the study. Eight trials with target LDL-c levels ≤100 mg/dL (2...

AIM: A stoma rod or bridge has been traditionally placed under the bowel loop while constructing loop colostomies. This is believed to prevent stomal retraction and provide better faecal diversion. However, the rod can cause complications such as mucosal congestion, oedema and necrosis. This single centre prospective randomized controlled trial compared outcomes after loop colostomy creation with and without a supporting stoma rod. The primary outcome studied was stoma retraction rate, and other stoma related complications were studied as secondary outcomes...

Bosma arhinia microphthalmia syndrome (BAMS) is an extremely rare and striking condition characterized by complete absence of the nose with or without ocular defects. We report here that missense mutations in the epigenetic regulator SMCHD1 mapping to the extended ATPase domain of the encoded protein cause BAMS in all 14 cases studied. All mutations were de novo where parental DNA was available. Biochemical tests and in vivo assays in Xenopus laevis embryos suggest that these mutations may behave as gain-of-function alleles...

Inositol 1,4,5-trisphosphate receptors (IP3Rs) are tetrameric intracellular channels through which many extracellular stimuli initiate the Ca(2+) signals that regulate diverse cellular responses. There is considerable interest in developing novel ligands of IP3R. Adenophostin A (AdA) is a potent agonist of IP3R and since some dimeric analogs of IP3R ligands are more potent than the corresponding monomer; we considered whether dimeric AdA analogs might provide agonists with increased potency. We previously synthesized traizolophostin, in which a simple triazole replaced the adenine of AdA, and showed it to be equipotent to AdA...

Leishmania parasites have evolved to endure the acidic phagolysosomal environment within host macrophages. How Leishmania cells maintain near-neutral intracellular pH and proliferate in such proton-rich milieu remains poorly understood. We report here that for thriving in acidic condition Leishmania major relies on a cytosolic and a cell surface carbonic anhydrase viz. LmCA1 and LmCA2. Upon exposure to acidic medium, intracellular pH of the LmCA1(+/-), LmCA2(+/-) and LmCA1(+/-): LmCA2(+/-) mutant strains dropped by varying extents that led to cell cycle delay, growth retardation and morphological abnormalities...

Surgery-first approach (SFA) has been a paradigm shift in the field of orthognathic surgery. Majority of the published cases that have been managed by this approach are of skeletal class III. This communication describes a patient of 18-year-old male diagnosed with skeletal class II malocclusion due to mandibular retognathism. He was managed with SFA and was using skeletal anchorage system to prevent postsurgical relapse. Bilateral saggital split ramus osteotomy was carried out to achieve the mandibular advancement of 7 mm...

The mechanisms behind the hereditary thrombocytosis induced by the thrombopoietin (THPO) receptor MPL P106L mutant remain unknown. A complete trafficking defect to the cell surface has been reported, suggesting either weak constitutive activity or nonconventional THPO-dependent mechanisms. Here, we report that the thrombocytosis phenotype induced by MPL P106L belongs to the paradoxical group, where low MPL levels on platelets and mature megakaryocytes (MKs) lead to high serum THPO levels, whereas weak but not absent MPL cell-surface localization in earlier MK progenitors allows response to THPO by signaling and amplification of the platelet lineage...

With immunochemotherapy, remission duration and survival in patients with chronic lymphocytic leukaemia is dependent on the level of minimal residual disease (MRD) after treatment. This phase II trial assessed alemtuzumab consolidation post-chemotherapy in patients who responded with persistent low levels of detectable disease. Blood was screened for MRD using multi-parameter flow cytometry, 6-24 months post-chemotherapy. MRD-positive participants received alemtuzumab 30 mg subcutaneously 3 times weekly for 6 weeks...

Cell-based assays have long been important within hit discovery paradigms; however, improving the disease relevance of the assay system can positively affect the translation of small-molecule drug discovery, especially if adopted in the initial hit identification assay. Consequently, there is an increasing need for disease-relevant assay systems capable of running at large scale, including the use of induced pluripotent stem cells and donor-derived primary cells. Major hurdles to adopting these assays for high-throughput screening are the cost, availability of cells, and complex protocols...

Fractional photothermolysis uses lasers to generate a pattern of microscopic columnar thermal lesions within the skin stimulating collagen remodeling. In this paper we investigate the use of Bessel beams as an alternative to conventional Gaussian beams in creating laser photothermal lesions of different aspect ratios in skin. We show for the first time the improved photothermal lesion depth-to-diameter aspect ratio using Bessel beams in ex vivo human skin as well as in numerical simulations using electric field Monte Carlo photon transport, finite difference methods and Arrhenius model...

Many countries have observed an increase in the incidence of invasive fungal infections (IFIs) over the past two decades with emergence of new risk factors and isolation of new fungal pathogens. Early diagnosis and appropriate antifungal treatment remain the cornerstones of successful outcomes. However, due to non-specific clinical presentations and limited availability of rapid diagnostic tests, in more than half of cases antifungal treatment is inappropriate. As a result, the emergence of antifungal resistance both in yeasts and mycelial fungi is becoming increasingly common...

The Biopharmaceutics Classification System (BCS) classifies pharmaceutical compounds based on their aqueous solubility and intestinal permeability. The BCS Class III compounds are hydrophilic molecules (high aqueous solubility) with low permeability across the biological membranes. While these compounds are pharmacologically effective, poor absorption due to low permeability becomes the rate-limiting step in achieving adequate bioavailability. Several approaches have been explored and utilized for improving the permeability profiles of these compounds...
