Background Epidemiological studies suggest an increasing global incidence of microscopic colitis, including collagenous colitis and lymphocytic colitis. Aims To investigate the incidence and prevalence of microscopic colitis in Denmark. Methods In a nationwide cohort study, we included all incident patients with a recorded diagnosis of collagenous colitis or lymphocytic colitis in the Danish Pathology Register between 2001 and 2016. Results A total of 14,302 microscopic colitis patients - 8,437 (59%) with collagenous and 5,865 (41%) with lymphocytic colitis - were identified during the study period. The prevalence in December 2016 was estimated to be 197.9 cases per 100,000 inhabitants. Microscopic colitis was more prevalent among females (n=10,127 (71%)), with a mean annual incidence of 28.8, compared to 12.3 per 100,000 person-years among males. The overall mean incidence during the study period was 20.7 per 100,000 person-years. Mean age at time of diagnosis was 65 (SD14) for microscopic colitis, 67 (SD13) for collagenous colitis and 63 (SD15) for lymphocytic colitis. The overall incidence increased significantly from 2.3 cases in 2001 to 24.3 cases per 100,000 person-years in 2016. However, the highest observed incidence of microscopic colitis was 32.3 cases per 100,000 person-years in 2011. Large regional differences were found, with the highest incidence observed in the least populated region. Conclusions The incidence of microscopic colitis in Denmark has increased 10-fold during the last 15 years and has now surpassed that of Crohn's disease and ulcerative colitis. However, incidence has stabilised since 2012, suggesting that a plateau has been reached.Inferring phylogenetic trees for individual homologous gene families is difficult because alignments are often too short, and thus contain insufficient signal, while substitution models inevitably fail to capture the complexity of the evolutionary processes. To overcome these challenges species tree-aware methods also leverage information from a putative species tree. However, only few methods are available that implement a full likelihood framework or account for horizontal gene transfers. Furthermore, these methods often require expensive data pre-processing (e.g., computing bootstrap trees), and rely on approximations and heuristics that limit the degree of tree space exploration. Here we present GeneRax, the first maximum likelihood species tree-aware phylogenetic inference software. It simultaneously accounts for substitutions at the sequence level as well as gene level events, such as duplication, transfer, and loss relying on established maximum likelihood optimization algorithms. GeneRax can infer rooted phylogenetic trees for multiple gene families, directly from the per-gene sequence alignments and a rooted, yet undated, species tree. We show that compared to competing tools, on simulated data GeneRax infers trees that are the closest to the true tree in 90% of the simulations in terms of relative Robinson-Foulds distance. On empirical datasets, GeneRax is the fastest among all tested methods when starting from aligned sequences, and it infers trees with the highest likelihood score, based on our model. GeneRax completed tree inferences and reconciliations for 1099 Cyanobacteria families in eight minutes on 512 CPU cores. Thus, its parallelization scheme enables large-scale analyses.

One plausible reason is the interaction of intrinsic vitamin D with other biological conditions such as malnutrition and chronic inflammation. Objective To explore the associations between serum levels of 25(OH)D, albumin, and all-cause mortality and further evaluate their interactions in elderly people. Design Population-based longitudinal study. check details Setting and participants Data were obtained from 1834 people aged 65 to 112 who had their serum 25(OH)D and albumin assayed at baseline in 2011. Participants' survival status was ascertained at the 2014 and 2018 follow-up survey waves. Main outcome measures All-cause mortality. Results Among the 1834 participants, both serum 25(OH)D and albumin concentrations were inversely associated with all-cause mortality (Ps less then 0.001). In addition, the interaction effect of 25(OH)D and albumin on all-cause mortality was observed among the participants (P = 0.001). In the group with a higher albumin level (≥40 g/L), participants with a lower level of 25(OH)D ( less then 50 nmol/L) had higher risk of mortality than their counterparts (hazard ratio, 1.92; 95% confidence interval, 1.45-2.56), and the association was more pronounced in women. In the group with a lower albumin level ( less then 40 g/L), the associations failed to reach statistical significance in all participants as well as in women and in men. Conclusions Serum 25(OH)D and albumin levels were inversely associated with all-cause mortality in Chinese older adults. The association between 25(OH)D and mortality was more pronounced in participants with higher albumin levels.As the number of farmers' markets and other direct-to-consumer marketing channels increases, it is crucial to understand the potential risks associated with consuming directly marketed animal products and fresh produce. The overall aim of this project was to assess the prevalence of Salmonella and generic E. coli in animal products and produce sold at farmers' markets in Northern California, allowing for the evaluation of food safety risks associated with consuming meat (e.g., beef, pork, and poultry) and fresh produce purchased from farmers' markets. Animal products and produce were purchased from a total of 44 certified farmers' markets in Northern California. Animal products and produce samples demonstrated a Salmonella spp. prevalence of 1.8% (6/338) and 0% (0/128), respectively, and a generic E. coli prevalence of 31.3% (40/128) for fresh produce. Generic E. coli was quantified using Most Probable Number (MPN). Generic E. coli concentration in produce ranged from zero to 2.96, with an overall average of 0.
