BACKGROUND: In sub-Saharan Africa, the burden of liver disease associated with chronic hepatitis B (HBV) and HIV is unknown. We characterized liver disease using aspartate aminotransferase-to-platelet ratio index (APRI) and FIB-4 in patients with HIV, HBV, and HIV/HBV co-infection in Tanzania. METHODS: Using a cross sectional design, we compared the prevalence of liver fibrosis in treatment-naive HIV mono-infected, HBV mono-infected, and HIV/HBV co-infected adults enrolled at Management and Development for Health (MDH)-supported HIV treatment clinics in Dar es Salaam, Tanzania...

The establishment of DNA methylation patterns in oocytes is a highly dynamic process marking gene-regulatory events during fertilization, embryonic development, and adulthood. However, after epigenetic reprogramming in primordial germ cells, how and when DNA methylation is re-established in developing human oocytes remains to be characterized. Here, using single-cell whole-genome bisulfite sequencing, we describe DNA methylation patterns in three different maturation stages of human oocytes. We found that while broad-scale patterns of CpG methylation have been largely established by the immature germinal vesicle stage, localized changes continue into later development...

PURPOSE: Congenital hand differences are infrequent phenomena, and their treatment represents a relatively small fraction of cases performed by hand surgeons. Little is known about the incidence of wound complications and acute postoperative problems given the relative rarity of these procedures. This study sought to characterize the incidence of complications within 30 days of surgery for congenital hand differences. METHODS: The National Surgical Quality Improvement Program (NSQIP) contains prospective data regarding 30-day morbidity from 64 pediatric centers across the United States...

Diagnosis and treatment of systemic amyloidosis depend on accurate identification of the specific amyloid fibril protein forming the tissue deposits. Confirmation of monoclonal immunoglobulin light chain amyloidosis (AL), requiring cytotoxic chemotherapy, and avoidance of such treatment in non-AL amyloidosis, are particularly important. Proteomic analysis characterises amyloid proteins directly. It complements immunohistochemical staining of amyloid to identify fibril proteins and gene sequencing to identify mutations in the fibril precursors...

OBJECTIVE: Adiponectin is found in human serum in three groups of multimers (high molecular weight [HMW], medium molecular weight [MMW], and low molecular weight [LMW]). Two ethnic-specific variants in ADIPOQ, G45R (Hispanic-Americans) and R55C (African-Americans), were previously reported. Although carriers of both variants had mean adiponectin levels ≤ 20% of those of noncarriers, they were not clinically different from noncarriers. To compare carriers of both variants and noncarriers, relative quantification of adiponectin isoforms to total adiponectin was performed on serum samples...

Interest in hemp (Cannabis sativa L.) is increasing due to the development of a new range of industrial applications based on bast fibers. However the variability of bast fiber yield and quality represents an important barrier to further exploitation. Primary and secondary fiber content was examined in two commercial hemp varieties (Fedora 17, Santhica 27) grown under contrasted sowing density and irrigation conditions. Both growing conditions and hemp varieties impact stem tissue architecture with a large effect on the proportion of secondary fibers but not primary fibers...

Clostridium difficile is the primary cause of healthcare associated diarrhoea globally and produces spores which are resistant to commonly used biocides and are able persist on contaminated surfaces for months. This study examined the effect of sublethal concentrations of the biocide sodium dichloroisocyanurate (NaDCC) on the viability of spores produced by 21 clinical isolates of C. difficile representing a range of PCR ribotypes. Spores exposed to 500 ppm NaDCC for 10 minutes exhibited between a 4 - 6 log10 reduction in viability which was independent of spore PCR ribotype...

Total chordal preservation is the standard for mitral valve replacement to maintain long-term left ventricular geometry. Whereas it is appropriate for functional and degenerative mitral regurgitation, the role of chordal sparing in rheumatic valve disease is less well understood, with limited evidence supporting total chordal sparing. Inasmuch as this autoimmune disease affects the subvalvular apparatus in addition to the leaflets, it can be expected to continue after surgical repair. Here we present 2 patients who experienced adverse events associated with total chordal sparing mitral replacement as a result of disease progression with rapid fibrous growth causing inflow obstruction and early prosthetic valve failure...

Molecular modeling studies were performed in order to gain insight into the binding mode and interaction of carborane-containing derivatives of indomethacin methyl ester with the cyclooxygenase 2 (COX 2) isoform, and to assess the predictive capability of the computational tools available for studying carboranes, a unique class of pharmacophores. Docking simulations were able to identify the correct binding mode and reproduced the experimental binding affinity trends with encouraging quality. Nevertheless, the docking results needed to be verified through extensive and resource intensive quantum chemical calculations, and the interpretation of the theoretical results would not have been straightforward without the supporting experimental data...

We assessed compliance of waterpipe product packaging and labelling with the Framework Convention on Tobacco Control's Article 11. We evaluated samples collected at a trade fair against ten domains: health warning location, size, use of pictorials, use of colour, and packaging information on constituents and emissions. We also evaluated waterpipe accessories (e.g., charcoal) for misleading claims. Ten of 15 tobacco products had health warnings on their principal display areas, covering a median of 22.4 per cent (interquartile range 19...

BACKGROUND: Staple line leaks after sleeve gastrectomy are dreaded complications. Many surgeons routinely perform an intraoperative leak test (IOLT) despite little evidence to validate the reliability, clinical benefit, and safety of this procedure. OBJECTIVES: To determine the efficacy of IOLT and if routine use has any benefit over selective use. SETTING: Eight teaching hospitals, including private, university, and military facilities. METHODS: A multicenter, retrospective analysis over a 5-year period...

BACKGROUND: Evolving immune-mediated therapeutic strategies for rheumatoid arthritis (RA) may benefit from an improved understanding of the complex role that T-cell activation plays in RA. This study assessed the potential of fluorine-18-labeled 9-β-d-arabinofuranosylguanine ([(18)F]F-AraG) positron emission tomography (PET) imaging to report immune activation in vivo in an adjuvant-induced arthritis (AIA) small animal model. METHODS: Using positron emission tomography-computed tomography imaging, uptake of [(18)F]F-AraG in the paws of mice affected by arthritis at 6 (acute) and 20 (chronic) days following AIA induction in a single paw was assessed and compared to uptake in contralateral control paws...

BACKGROUND: Mutations in the tail of histone H3 (K27M) are frequently found in pediatric midline high-grade glioma's but have rarely been reported in other malignancies. Recently, recurrent somatic nucleotide variants in histone H3 (H3 K27M) have been reported in group A posterior fossa ependymoma (EPN_PFA), an entity previously described to have no recurrent mutations. However, the true incidence of H3 K27M mutations in EPN_PFA is unknown. METHODS: In order to discern the frequency of K27M mutations in histone H3 in EPN_PFA, we analyzed 151 EPN_PFA previously profiled with genome-wide methylation arrays using a validated droplet digital PCR assay...

Cognitive Behavioural Therapy (CBT) is a widely used psychotherapeutic intervention for suicide prevention despite its efficacy for suicide prevention in adults remaining ambiguous. Reluctance or inability to access face-to-face help suggests that e-health delivery may be a valuable resource for suicidal people. The aim of this study was to systematically review and conduct meta-analysis on research assessing the efficacy of CBT delivered via face-to-face and e-health for suicidal ideation and behaviour. A comprehensive literature search of MEDLINE, PsycINFO, Scopus, PubMed and The Cochrane Central Register of Controlled Trials was conducted...
