Homelessness is associated with a multitude of poor health outcomes. However, the full extent of the risks associated with homelessness are not possible to quantify without reliable population data. Here, we outline three federal, publicly-available data sources available to estimate the number of people experiencing homelessness in the United States. We describe the appropriate uses and limitations of each data source in the context of infectious disease epidemiology. These data sources provide an opportunity to expand current research and develop actionable analyses.Machine learning is gaining prominence in the health sciences, where much of its use has focused on data-driven prediction. However, machine learning can also be embedded within causal analyses, potentially reducing biases arising from model misspecification. Using a question-and-answer format, we provide an introduction and orientation for epidemiologists interested in using machine learning but concerned about potential bias or loss of rigor due to use of 'black box' models. We conclude with sample code that may lower the barrier to entry to using these techniques.A large number of proteins involved in RNA metabolism possess a double-stranded RNA-binding domain (dsRBD), whose sequence variations and functional versatilities are still being recognized. All dsRBDs have a similar structural fold α1-L1-β1-L2-β2-L3-β3-L4-α2 (α represents an α-helix, β a β-sheet, and L a loop conformation between the well-defined secondary structures). Our recent work revealed that the dsRBD in Drosha, which is involved in animal microRNA (miRNA) biogenesis, differs from other dsRBDs by containing a short insertion in its L1 region and that this insertion is important for Drosha function. We asked why the same insertion is excluded in all other dsRBDs and proposed that a longer L1 may be detrimental to their functions. BMS-232632 In this study, to test this hypothesis, we inserted the Drosha sequence into several well-known dsRBDs from various organisms. Gel mobility shift assay demonstrated that L1 extension invariably reduced RNA binding by these dsRBDs. In addition, such a mutation in Dicer, another protein involved in miRNA biogenesis, impaired Dicer's ability to process miRNAs, which led to de-repression of reporter expression, in human cells. Taken together, our results add to the growing appreciation of the diversity in dsRBDs and suggest that dsRBDs have intricate structures and functions that are sensitive to perturbations in the L1 region.Vincristine-induced peripheral neuropathy (VIPN) is a prevalent and painful complication in cancer patients that lacks effective treatments. In this issue of JEM, Starobova et al. (2021. J. Exp. Med.https//doi.org/10.1084/jem.20201452) report that VIPN is driven by innate immune system activation, a discovery that unlocks immunotherapies as potential treatments.

The primary purpose of this research was to describe nurse and pharmacist knowledge of setup requirements for intravenous (IV) smart pumps that require head height differentials for accurate fluid flow.

A secondary analysis of anonymous electronic survey data using a database of prerecruited clinicians was conducted. A survey was sent by email to 173 pharmacists and 960 nurses. The response rate for pharmacists was 58% (100 of 173), and the response rate for nurses was 52% (500 of 960). After removing respondents who did not provide direct care and who did not use a head height differential IV infusion system, the final sample for analysis was 186 nurses and 25 pharmacists.

Overall, less than one-half of respondents (40%) were aware that manufacturer guidelines for positioning the primary infusion bag relative to the infusion pump were available. Slightly more (49.5%) were aware of the required head height differentials for secondary infusion. Only five respondents selected the correct primary head height, eight respondents selected the correct secondary head height, and one respondent selected both the correct primary and secondary head heights.

The results of this study identify a substantial lack of knowledge among frontline clinicians regarding manufacturer recommendations for accurate IV administration of primary and secondary infusions for head height differential infusion systems. Both increased clinician education and innovative technology solutions are needed to improve IV smart pump safety and usability.

PubMed, Scopus, and Web of Science databases and Google Scholar were searched up to 26 November 2020. All retrospective and prospective cohort, cross-sectional, case-control, and randomized controlled trial studies that investigated the relation between 25(OH)D and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and COVID-19 severity were included. Thirty-nine studies were included in the current systematic review. In studies that were adjusted (OR 1.77; 95% CI 1.24, 2.53; I2 44.2%) and nonadjusted for confounders (OR 1.75; 95% CI 1.44, 2.13; I2 33.0%) there was a higher risk of SARS-CoV-2 infection in the vitamin D deficiency (VDD) group. Fifteen studies evaluated associations between VDD and composite severity. In the studies that were adjusted (OR 2.57; 95% CI 1.65, 4.01; I2 = 0.0%spitalization, and pulmonary involvement, the evidence is currently inconsistent and insufficient.Elevated circulating trimethylamine N-oxide (TMAO) concentrations have been observed in patients with chronic kidney disease (CKD). We aimed to systematically estimate and quantify the association between TMAO concentrations and kidney function. The PubMed, EMBASE, Cochrane Library, Scopus, and Web of Science databases were systematically searched from 1995 to 1 June, 2020, for clinical studies on circulating TMAO concentrations and kidney function indicators. We used R software to conduct meta-analyses of the extracted data. A cumulative meta-analysis was applied to test whether health status affected the pooled effect value. Meta-regression and subgroup analyses were performed to identify possible sources of heterogeneity. Ultimately, we included a total of 32 eligible clinical studies involving 42,062 participants. In meta-analyses of continuous-outcome variables, advanced CKD was associated with a 67.9 μmol/L (95% CI 52.7, 83.2; P less then 0.01) increase in TMAO concentration, and subjects with high concentrations of TMAO had a 12.
