Zika virus (ZIKV) is a flavivirus related to the Dengue, yellow fever and West Nile viruses. Since the explosive outbreaks of ZIKV in Latin America in 2015, a sudden increase in the number of microcephaly cases has been observed in infants of women who were pregnant when they contracted the virus. The severity of this condition raises grave concerns, and extensive studies on the possible link between ZIKV infection and microcephaly have been conducted. There is substantial evidence suggesting that there is a causal link between ZIKV and microcephaly, however, future studies are warranted to solidify this association...

We applied an interdisciplinary approach to investigate kinship patterns and funerary practices during the middle Neolithic. Genetic studies, radiocarbon dating, and taphonomic analyses were used to examine two grave clusters from Krusza Zamkowa, Poland. To reconstruct kinship and determine biological sex, we extracted DNA from bones and teeth, analyzed mitochondrial genomes and nuclear SNPs using the HID-Ion AmpliSeq™ Identity panel generated on Illumina and Ion Torrent platforms, respectively. We further dated the material (AMS (14)C) and to exclude aquatic radiocarbon reservoir effects, measures of carbon and nitrogen stable isotopes for diet reconstruction were used...

Zirconium-89 finds broad application for use in positron emission tomography. Its cyclotron production has been limited by the heat transfer from yttrium targets at high beam currents. A spot welding technique allows a three-fold increase in beam current, without affecting (89)Zr quality. An yttrium foil, welded to a jet-cooled tantalum support base accommodates a 50µA proton beam degraded to 14MeV. The resulting activity yield of 48±4 MBq/(μA∙hr) now extends the outreach of (89)Zr for a broader distribution...

BACKGROUND: A short course of potassium iodide (SSKI) has been traditionally used to prepare patients with Graves' disease for thyroidectomy. The rationale for this treatment has evolved over time; from control of hyperthyroidism to facilitating surgery by making the gland less friable and bloody. METHODS: Randomized trial of preoperative SSKI vs no SSKI to test whether that is true. RESULTS: Mean estimated blood loss in the SSKI group (62 mL) was less than in the control group (162 mL) as was the median estimated blood loss (50 vs 140 mL)...

CONTEXT: The sources and biological impact of 3,3',5,5' tetraiodothyroacetic acid (TA4) are uncertain. CD34(+) fibrocytes express several proteins involved in the production of thyroid hormones. They infiltrate the orbit in Graves' disease (GD), an autoimmune process known as thyroid-associated ophthalmopathy. It appears that the thyrotropin receptor (TSHR) plays an important role in the pathogenesis of TAO. OBJECTIVE: To quantify levels of TA4 in healthy subjects and those with Graves' disease...

BACKGROUND: Although the primary objective of forensic DNA analyses of unidentified human remains is positive identification, cases involving historical or archaeological skeletal remains often lack reference samples for comparison. Massively parallel sequencing (MPS) offers an opportunity to provide biometric data in such cases, and these cases provide valuable data on the feasibility of applying MPS for characterization of modern forensic casework samples. In this study, MPS was used to characterize 140-year-old human skeletal remains discovered at a historical site in Deadwood, South Dakota, United States...

BACKGROUND: Functional magnetic resonance (MR) imaging of atheroma using contrast media enables assessment of the systemic severity of atherosclerosis in different arterial beds. Whether black-blood imaging has similar ability remains widely unexplored. In this study, we evaluate whether black-blood imaging can differentiate carotid plaques of patients with and without coronary artery disease (CAD) in terms of morphological and biomechanical features of plaque vulnerability, thereby allowing assessment of the systemic severity nature of atherosclerosis in different arterial beds...

BACKGROUND: Three European centers have recently reported dramatic failures of the STRATOS titanium system, approved in Europe and the United States since 2007 and meant for pectus repair, without detailed exploration of its causes. METHODS: Failed implants (fractures or loosened crimp connectors) were surgically explanted from 12 patients and biopsies taken from surrounding discolored tissue. Detailed failure analysis was performed to find the cause of failures...

BACKGROUND: Experimental studies demonstrate beneficial immunological and hemodynamic effects of estradiol in animal models of sepsis. This raises the question whether estradiol contributes to sex differences in the incidence and outcomes of sepsis in humans. Yet, total estradiol levels are elevated in sepsis patients, particularly nonsurvivors. Bioavailable estradiol concentrations have not previously been reported in septic patients. The bioavailable estradiol concentration accounts for aberrations in estradiol carrier protein concentrations that could produce discrepancies between total and bioavailable estradiol levels...

BACKGROUND: Graves' disease (GD) and Hashimoto's disease (HD) are autoimmune thyroid diseases distinguished by the presence or absence of an anti-thyroid stimulating hormone receptor (TSHR) antibody (TRAb). TSHR gene polymorphisms determine the amount of TSHR expressed, which may in turn influence TRAb production. The FANTOM5 project identified six GD-associated SNPs within the enhancer regions of TSHR and unknown genes. In this study, we examined the association of 11 TSHR and unknown gene polymorphisms, 5 of which are located in TSHR enhancer regions, with the development and prognosis of GD and HD...

Rituximab (RTX) use in open label series has been associated with very encouraging responses in patients with active and moderate-to-severe Graves' Orbitopathy (GO). Recently randomized controlled trials of RTX have been performed in such patients in order to answer the question of clinical efficacy and the safety profile of this agent. That data, reported separately, focused on Clinical Activity Score (CAS) and indicated in one trial a strong benefit of RTX in comparison with IV glucocorticoids while the other trial noted the absence of a benefit by comparison with placebo...

OBJECTIVE: To determine overall survival (OS) and factors associated with OS after pelvic exenteration for uterine cancer. METHODS: Women with uterine cancer who underwent exenteration (n=1160) were identified from the 1998-2011 National Cancer Data Base. Kaplan-Meier and multivariate Cox proportional-hazards survival analyses were performed to test for associations of potential explanatory variables with OS. Analyzed confounders included age, comorbidity score, insurance status, income, distance from home to treatment center, stage, distant and nodal metastasis, tumor size, surgical margin status, exenteration type, and treatment with radiation and/or chemotherapy...

Avoidance of apoptosis is critical for the development and sustained growth of tumours. The pro-survival protein myeloid cell leukemia 1 (MCL1) is overexpressed in many cancers, but the development of small molecules targeting this protein that are amenable for clinical testing has been challenging. Here we describe S63845, a small molecule that specifically binds with high affinity to the BH3-binding groove of MCL1. Our mechanistic studies demonstrate that S63845 potently kills MCL1-dependent cancer cells, including multiple myeloma, leukaemia and lymphoma cells, by activating the BAX/BAK-dependent mitochondrial apoptotic pathway...

Introduction: Acute severe colitis is a potentially lethal medical emergency and, even today, its treatment remains a challenge for clinicians and surgeons. Intravenous corticoid therapy, which was introduced into the therapeutic arsenal in the 1950s, continues to be the first-line treatment and, for patients who are refractory to this, the rescue therapy may consist of clinical measures or emergency colectomy. Objective: To evaluate the indications for and results from drug rescue therapy (cyclosporine, infliximab and tacrolimus), and to suggest a practical guide for clinical approaches...

Background and purpose - It is unclear whether metal particles and ions produced by mechanical wear and corrosion of hip prostheses with metal-on-metal (MoM) bearings have systemic adverse effects on health. We compared the risk of heart failure in patients with conventional MoM total hip arthroplasty (THA) and in those with metal-on-polyethylene (MoP) THA. Patients and methods - We conducted a retrospective cohort study using data from the Australian Government Department of Veterans' Affairs health claims database on patients who received conventional THA for osteoarthritis between 2004 and 2012...

We report a patient with resistance to thyroid hormone beta caused by a novel <i>THRB</i> gene mutation and coexisting pituitary microadenoma. A 41-year-old Thai woman presented with elevated serum thyroid hormone levels and non-suppressed TSH. MRI showed a 4x2-mm pituitary adenoma. Five of her relatives had similar thyroid tests abnormalities, but a sister had Graves' disease. TPO and TG antibodies were positive in all affected family members except for a 4.5 year-old. Lack of thyrotoxic symptoms and TSH suppression by T3, indicated incidentaloma rather than a TSH-secreting pituitary adenoma...
