Potential risk factors of ovarian cancer and analysis of CA125, a biomarker used for its monitoring and diagnosis.

Ovarian cancer (OC) is the fourth most common cancer among Pakistani, Scottish and Chinese women. The aim of the present study was to determine the association of potential risk factors with OC and analysis of Cancer Antigen 125 (CA125) in its monitoring and diagnosis. A total of 200 patients diagnosed with OC were included in this study.

Bovine brucellosis in Pakistan; an analysis of engagement with risk factors in smallholder farmer settings.

A cross-sectional study was conducted to estimate the seroprevalence of bovine brucellosis in smallholder farms in seven regions in Pakistan, identify herd and individual level risk factors for seropositivity and assess the level of engagement of farmers with risk factors. In total, 1063 cattle and buffalo belonging to 420 herds in seven districts were sampled. The Rose Bengal test (RBT), indirect enzyme-linked immunosorbent assay (I-ELISA) and competitive enzyme-linked immunosorbent assay (C-ELISA) were used for the serological diagnosis of bovine brucellosis on all the serum samples.

Reaction norm analysis of pig growth using environmental descriptors based on alternative traits.

Contemporary group (CG) estimates of different phenotypes have not been widely explored for pigs. The objective of this study was to extend the traits used to derive environmental descriptors of the growing pig, to include CG estimates of early growth between birth and start of feed intake test (EADG), growth during feed intake test (TADG), lifetime growth (ADG), daily feed intake (DFI), backfat (BF) and muscle depth (MD). Pedigree and performance records (n = 7,746) from a commercial Australian piggery were used to derive environmental descriptors based on CG estimates of these six traits.

History of childhood adversity and coping strategies: Positive flow and creative experiences.

Background: Acquiring more complex coping strategies despite a history of childhood adversity may transpire in settings outside the family home.

Objectives: The objectives of this cross-sectional study included investigating coping strategies under stressful situations in a non-clinical sample of active athletes and performing artists.

Participants And Setting: In this community and university sample (n = 577), 40.

Solving the problem with stannous fluoride: Extrinsic stain.

Background: This article highlights a stabilized stannous fluoride (SnF) dentifrice that, in addition to being efficacious against caries, gingivitis, and dentin hypersensitivity, demonstrates high-performing stain prevention and removal efficacy.

Methods: An in vitro stain prevention model evaluated the efficacy of Colgate Total containing 0.454% SnF and 1% zinc phosphate compared with Crest Pro-Health Whitening Power (The Procter & Gamble Company) and a nonabrasive SnF gel.

Antifungal susceptibility of Saccharomyces cerevisiae and therapy in a murine model of disseminated infection.

Background: The incidence of systemic infections by Saccharomyces cerevisiae has increased in recent years, especially among immunocompromised patients. Amphotericin B, voriconazole or echinocandins have been used with favorable outcome against systemic infections by this fungus. However, clinical experience is limited and no in vivo studies have been conducted.

Genetic and environmental determinants of stressful life events and their overlap with depression and neuroticism.

Stressful life events (SLEs) and neuroticism are risk factors for major depressive disorder (MDD). However, SLEs and neuroticism are heritable and genetic risk for SLEs is associated with risk for MDD. We sought to investigate the genetic and environmental contributions to SLEs in a family-based sample, and quantify genetic overlap with MDD and neuroticism.

Quantifying the health challenges in an Australian piggery using medication records for the definition of disease resilience1.

Disease resilience is the ability to maintain performance and health, despite infection challenges in the environment. The evaluation of disease resilience requires measures of environment infection challenges, along with other environmental challenges. The overall objective of this study was to define disease resilience using pedigree, production, and medication records from an Australian herd of Large White pigs.

Genome-wide association study of antidepressant treatment resistance in a population-based cohort using health service prescription data and meta-analysis with GENDEP.

Antidepressants demonstrate modest response rates in the treatment of major depressive disorder (MDD). Despite previous genome-wide association studies (GWAS) of antidepressant treatment response, the underlying genetic factors are unknown. Using prescription data in a population and family-based cohort (Generation Scotland: Scottish Family Health Study; GS:SFHS), we sought to define a measure of (a) antidepressant treatment resistance and (b) stages of antidepressant resistance by inferring antidepressant switching as non-response to treatment.

A validation of the diathesis-stress model for depression in Generation Scotland.

Depression has well-established influences from genetic and environmental risk factors. This has led to the diathesis-stress theory, which assumes a multiplicative gene-by-environment interaction (GxE) effect on risk. Recently, Colodro-Conde et al.

A national study of autogenous arteriovenous access use and patency in a contemporary hemodialysis population.

Objective: The predicted outcomes of autogenous arteriovenous (AV) hemodialysis access creation are predominantly based on historical data; however, both the hemodialysis population and clinical practices have changed significantly during the last decade. This study examined contemporary AV access clinical use and patencies.

Methods: A multicenter observational cohort study was performed of all new AV accesses created in Scotland in 2015.

Two polymorphic forms of the oxathiin systemic fungicide active carboxine.

Two polymorphic crystal forms of the title compound, CHNOS (systematic name: 6-methyl--phenyl-2,3-di-hydro-1,4-oxathiine-5-carboxamide), were isolated from a truncated, (12 solvent), polymorph screen on pure lyophillized material. Crystals of form 1 were obtained from all solvents included in the screen with the exception of methanol. As isolated from aceto-nitrile the crystals are triclinic, space group with = 2.

Genome-wide interaction study of a proxy for stress-sensitivity and its prediction of major depressive disorder.

Individual response to stress is correlated with neuroticism and is an important predictor of both neuroticism and the onset of major depressive disorder (MDD). Identification of the genetics underpinning individual differences in response to negative events (stress-sensitivity) may improve our understanding of the molecular pathways involved, and its association with stress-related illnesses. We sought to generate a proxy for stress-sensitivity through modelling the interaction between SNP allele and MDD status on neuroticism score in order to identify genetic variants that contribute to the higher neuroticism seen in individuals with a lifetime diagnosis of depression compared to unaffected individuals.

Evaluating Perceptions of Self-efficacy and Quality of Life in Patients Having Coronary Artery Bypass Grafting and Their Family Caregivers.

Background: Self-efficacy is a critical factor for quality of life in patients who undergo coronary artery bypass grafting, as well as for their family caregivers. However, there is lack of knowledge about whether patients' self-efficacy and caregivers' perceptions of patient self-efficacy are associated with quality of life in patient and caregiver dyads.

Objectives: The aims of this study were to compare self-efficacy and quality of life between patients and family caregivers and to examine whether patients' and caregivers' perceptions of patient self-efficacy were associated with their own and their partner's quality of life in patient and caregiver dyads who were waiting for patients' coronary artery bypass grafting.

Does Village Chicken-Keeping Contribute to Young Children's Diets and Growth? A Longitudinal Observational Study in Rural Tanzania.

There is substantial current interest in linkages between livestock-keeping and human nutrition in resource-poor settings. These may include benefits of improved diet quality, through animal-source food consumption and nutritious food purchases using livestock-derived income, and hazards of infectious disease or environmental enteric dysfunction associated with exposure to livestock feces. Particular concerns center on free-roaming chickens, given their proximity to children in rural settings, but findings to date have been inconclusive.

The prognostic role of PD-L1 expression for survival in head and neck squamous cell carcinoma: A systematic review and meta-analysis.

Background: Programmed death-ligand 1 (PD-L1) is an immune checkpoint that is primarily located on the surface of tumor cells. PD-L1 expression detected by immunohistochemistry (IHC) assays has been widely studied to predict survival outcomes in head and neck squamous cell carcinoma (HNSCC) recently. We aimed to review comprehensively the prognostic role of PD-L1 expression for survival in HNSCC.

Maintaining lower limb access with the HeRO device.

Central venous catheters (CVC) remain a mainstay of vascular access particularly for incident patients,
but lead to central vein stenosis (CVS) in up to 1 in 6 patents. This often leads to establishing dialysis access in the groin which in turn may result in development of CVS in the lower body, although this is poorly reported. The HeRO device was designed to address CVS by bypassing the stenosed veins with a nitinol-reinforced silicone tube into the right atrium, which acts as an outflow conduit attached to an arterial inflow.

Rainfall and groundwater use in rural Kenya.

This study examines the relationship between rainfall and groundwater use in rural Kenya, using automatically-transmitted hourly data from handpumps (n = 266), daily rainfall records (n = 19), and household survey data (n = 2508). We demonstrate a 34% reduction in groundwater use during the wet season compared to the dry season, suggesting a large shift from improved to unimproved sources in the wet season. By cross-correlating handpump and rainfall time series, we also reveal substantial short-term changes in groundwater pumping observed immediately following heavy rainfall.

Quantification of plasma corticosterone in juvenile farmed saltwater crocodiles (Crocodylus porosus) using current Australian Code of Practice guidelines.

Saltwater crocodiles (Crocodylus porosus) across three size categories (hatchlings, grower and harvest-size) were repeatedly blood sampled on two farms in the Northern Territory, Australia to determine reference plasma corticosterone (CORT; crocodilian stress hormone) levels. The mean CORT values for hatchlings (<1 year old), growers (1-3 years) and harvest-size individuals (2 + years) were 1.65 ± 0.

Tryptophan-like fluorescence as a measure of microbial contamination risk in groundwater.

Microbial water quality is frequently assessed with a risk indicator approach that relies on Escherichia coli. Relying exclusively on E. coli is limiting, particularly in low-resource settings, and we argue that risk assessments could be improved by a complementary parameter, tryptophan-like fluorescence (TLF).

Human milk oligosaccharides and infant gut bifidobacteria: Molecular strategies for their utilization.

Breast milk is the gold standard in infant nutrition. In addition to provide essential nutrients for the newborn, it contains multiple bioactive molecules that provide protection and stimulate proper development. Human milk oligosaccharides (HMO) are complex carbohydrates abundant in breast milk.

Development of a new clinical mastitis detection method for automatic milking systems.

This study investigated the potential for accurate detection of clinical mastitis (CM) in an automatic milking system (AMS) using electronic data from the support software. Data from cows were used to develop the model, which was then tested on 2 independent data sets, 1 with 311 cows (same farm but from a different year) and 1 with 568 cows (from a different farm). In addition, the model was used to test how well it could predict CM 1 to 3 d before actual clinical diagnosis.

Rediscovering the value of families for psychiatric genetics research.

As it is likely that both common and rare genetic variation are important for complex disease risk, studies that examine the full range of the allelic frequency distribution should be utilized to dissect the genetic influences on mental illness. The rate limiting factor for inferring an association between a variant and a phenotype is inevitably the total number of copies of the minor allele captured in the studied sample. For rare variation, with minor allele frequencies of 0.

Predictors of oropharyngeal cancer survival in Europe.

Objectives: HPV16-positive oropharyngeal cancer (OPC) patients experience better outcomes compared to HPV16-negative patients. Currently, strategies for treatment de-escalation are based on HPV status, smoking history and disease stage. However, the appropriate cut-point for smoking and the role of other non-clinical factors in OPC survival remains uncertain.
