The use of the magnetic sphincter augmentation (MSA) in patients with de novo or persistent gastroesophageal reflux disease (GERD) after sleeve gastrectomy has not been thoroughly investigated.

The aim of this study is to evaluate the efficacy of MSA device placement in improving GERD symptoms and reducing anti-reflux medication usage in patients with persistent or de novo GERD after sleeve gastrectomy.

This is a retrospective analysis of patients who underwent laparoscopic MSA device placement between January 2018 and July 2020 after sleeve gastrectomy.

A total of twenty-two patients met inclusion criteria. Twenty patients were female (91%) and two patients were male (9%). All patients were taking anti-reflux medications daily to control GERD symptoms prior to MSA device placement. There was a significant improvement in the mean GERD-HRQL survey scores when comparing scores prior to (43.8) and after (16.7) MSA device placement (p < 0.0001). Majority of the patients did well without any post-operatdditional risks. We show an improvement in reflux symptoms after MSA device placement as evidenced by decreased post-operative GERD-HRQL scores, decreased anti-acid medication usage, and overall patient satisfaction with the procedure. Further prospective and comparative studies with longer term follow-up are needed to validate the use of MSA in patients who have undergone sleeve gastrectomy.
Single nucleotide polymorphisms (SNPs) in vitamin D metabolism pathway genes are associated with circulating 25-hydroxyvitamin D (25(OH)D) in adults. Less is known about the relationships between mother and offspring SNPs and umbilical cord blood 25(OH)D.

(1) To undertake a meta-analysis of the relationships of maternal and offspring SNPs in the vitamin D metabolism pathway and cord blood 25(OH)D in pregnant women including novel data; and (2) to examine these relationships in women who received antenatal cholecalciferol supplementation in a clinical trial.

Novel data analysis from an observational mother-offspring cohort study (Southampton Women's Survey) and the MAVIDOS double-blind, randomized, placebo-controlled trial of 1000 IU/day cholecalciferol supplementation in pregnancy, and an electronic literature search of published studies in PubMed up to 31 July 2021. Studies reporting associations between rs12785878 (DHCR7), rs10741657 (CYP2R1), rs6013897 (CYP24A1), or rs2282679 (GC) and cord blood 25(Ors1074657 and rs613897 were not associated with cord blood 25(OH)D.

Common genetic variation in the vitamin D metabolism pathway is associated with umbilical cord blood 25(OH)D.

Taking a trauma informed care approach has demonstrated positive outcomes for services for people in the general population. Given the increased vulnerability to psychological trauma for adults with an intellectual disability, this study explores what residential staff know about trauma and trauma informed care.

Thirty-two staffs representing three staff groups direct care staff; managers; and specialist practitioners, were interviewed using semi-structured interviews, which were analysed following a structured framework.

Each staff group held different perspectives in their knowledge of trauma and trauma informed care. Limitations were noted in staffs' knowledge of trauma, implementation of evidence-based supports, and access to specialist services for adults with an intellectual disability. All participants highlighted their training needs regarding trauma.

Increased training on recognising and responding to trauma is needed among community staff supporting those with a trauma history if organisations are to move towards trauma informed care.

Similarly to coding genes, we propose that tumor suppressor miRNAs must show evidence of genetic or epigenetic inactivation in cancers, and exhibit an anti-tumorigenic (e.g., anti-proliferative) activity under endogenous expression levels. Here we observe that this definition excludes the most extensively studied tumor suppressor candidate miRNA, miR-34a. In analyzable cancer types, miR-34a does not appear to be down-regulated in primary tumors relatively to normal adjacent tissues. Deletion of miR-34a is occasionally found in human cancers, but it does not seem to be driven by an anti-tumorigenic activity of the miRNA, since it is not observed upon smaller, miR-34a-specific alterations. Its anti-proliferative action was observed upon large, supra-physiological transfection of synthetic miR-34a in cultured cells, and our data indicates that endogenous miR-34a levels do not have such an effect. Our results therefore argue against a general tumor suppressive function for miR-34a, providing an explanation to the lack of efficiency of synthetic miR-34a administration against solid tumors.Recent evidence suggests that the relationships between climate and boreal tree growth are generally non-stationary; however, it remains uncertain whether the relationships between climate and carbon (C) fluxes of boreal forests are stationary or have changed over recent decades. In this study, we used continuous eddy-covariance and microclimate data over 21 years (1996-2016) from a 100-year-old trembling aspen stand in central Saskatchewan, Canada to assess the relationships between climate and ecosystem C and water fluxes. Over the study period, the most striking climatic event was a severe, 3-year drought (2001-2003). Gross ecosystem production (GEP) showed larger interannual variability than ecosystem respiration (Re ) over 1996-2016, but Re was the dominant component contributing to the interannual variation in net ecosystem production (NEP) during post-drought years. The interannual variations in evapotranspiration (ET) and C fluxes were primarily driven by temperature and secondarily by water availability. Two-factor linear models combining precipitation and temperature performed well in explaining the interannual variation in C and water fluxes (R2  > .5). The temperature sensitivities of all three C fluxes (NEP, GEP and Re ) declined over the study period (p  less then  .05), and, as a result, the phenological controls on annual NEP weakened. The decreasing temperature sensitivity of the C fluxes may reflect changes in forest structure, related to the over-maturity of the aspen stand at 100 years of age, and exacerbated by high tree mortality following the severe 2001-2003 drought. These results may provide an early warning signal of driver shift or even an abrupt status shift of aspen forest dynamics. They may also imply a universal weakening in the relationship between temperature and GEP as forests become over-mature, associated with the structural and compositional changes that accompany forest ageing.Imbalance in the finely orchestrated system of chromatin-modifying enzymes is a hallmark of many pathologies such as cancers, since causing the affection of the epigenome and transcriptional reprogramming. Here, we demonstrate that a loss-of-function mutation (LOF) of the major histone lysine methyltransferase SETDB1 possessing oncogenic activity in lung cancer cells leads to broad changes in the overall architecture and mechanical properties of the nucleus through genome-wide redistribution of heterochromatin, which perturbs chromatin spatial compartmentalization. Together with the enforced activation of the epithelial expression program, cytoskeleton remodeling, reduced proliferation rate and restricted cellular migration, this leads to the reversed oncogenic potential of lung adenocarcinoma cells. These results emphasize an essential role of chromatin architecture in the determination of oncogenic programs and illustrate a relationship between gene expression, epigenome, 3D genome and nuclear mechanics.
Sociocultural influences, including an increasing pressure for fashion models to maintain a thin body frame may be crucial in the development of eating disorders. The present study aimed to establish whether fashion models are more likely than non-models to develop eating disorders.

Female fashion models were selected by snowball sampling (n=179, mean age 25.9 SD=4.70years). They were compared with an age adjusted control group (n=261, mean age 25.0 SD=4.97years). Participants completed an online questionnaire containing the Eating Disorder Inventory.

The average BMI of the fashion models was in the underweight range (mean BMI=18.1 SD=1.68). Gefitinib concentration The BMI of the control group was significantly higher (mean=22.1 SD=4.23, p<0.001). The frequency of simulated anorexia nervosa was 3.9% among the fashion models and 1.1% in the control group (p=0.057). 14.6% of the models showed subclinical anorexia nervosa symptoms versus 2.7% in the control group (p<0.001). The ratio of bulimia nervosa and subclinical bulimia nervosa showed no significant difference between the two groups.

Female fashion models showed no significant difference from the control group in the frequency of anorexia nervosa and bulimia nervosa but had a significantly higher frequency of the subclinical form of anorexia nervosa.

Applications that use k-mers include genome assembly and alignment. However, the wider bioinformatic use of these short sequences has challenges related to the massive scale of genomic sequence data. A single human genome assembly has billions of k-mers. As a result, the computational requirements for analyzing k-mer information is enormous, particularly when involving complete genome assemblies. To address these issues, we developed a new indexing data structure based on a hash table tuned for the lookup of short sequence keys. This web application, referred to as KmerKeys, provides performant, rapid query speeds for cloud computation on genome assemblies. We enable fuzzy as well as exact sequence searches of assemblies. To enable robust and speedy performance, the website implements cache-friendly hash tables, memory mapping and massive parallel processing. Our method employs a scalable and efficient data structure that can be used to jointly index and search a large collection of human genome assembly information. One can include variant databases and their associated metadata such as the gnomAD population variant catalogue. This feature enables the incorporation of future genomic information into sequencing analysis. KmerKeys is freely accessible at https//kmerkeys.dgi-stanford.org.
Technological advances have led to cancer prognostication that is increasingly accurate but often unalterable. However, a reliable prognosis of limited life expectancy can cause psychological distress. People should carefully consider offers of prognostication, but little is known about how and why they decide on prognostication. Using uveal melanoma (UM) patients, we aimed to identify (i) how and why do people with UM decide to accept prognostication and (ii) alignment and divergence of their decision-making from conceptualizations of a 'well-considered' decision.

UM provides a paradigm to elucidate clinical and ethical perspectives on prognostication, because prognostication is reliable but prognoses are largely nonameliorable. We used qualitative methods to examine how and why 20 UM people with UM chose prognostication. We compared findings to a template of 'well-considered' decision-making, where 'well-considered' decisions involve consideration of all likely outcomes.

Participants wanted prognostication to reduce future worry about uncertain life expectancy.
