There are limited data on how vedolizumab (VDZ) impacts extraintestinal manifestations (EIMs) in inflammatory bowel disease (IBD). The aim of this study was to determine the clinical outcomes of EIMs after initiation of VDZ for patients with IBD.
 
  A multicenter retrospective study of patients with IBD who received at least 1 dose of VDZ between January 1, 2014 and August 1, 2019 was conducted. The primary outcome was the rate of worsening EIMs after VDZ. Secondary outcomes were factors associated with worsening EIMs and peripheral arthritis (PA) specifically after VDZ.
 
  A total of 201 patients with IBD (72.6% with Crohn disease; median age 38.4 years (interquartile range, 29-52.4 years); 62.2% female) with EIMs before VDZ treatment were included. The most common type of EIM before VDZ was peripheral arthritis (PA) (68.2%). Worsening of EIMs after VDZ occurred in 34.8% of patients. There were no statistically significant differences between the worsened EIM (n = 70) and the stable EIM (n = 131) groups in term of age, IBD subtype, or previous and current medical therapy. We found that PA was significantly more common in the worsening EIM group (84.3% vs 59.6%; P < 0.01). Worsening of EIMs was associated with a higher rate of discontinuation of VDZ during study follow-up when compared with the stable EIM group (61.4% vs 44%; P = 0.02). Treatment using VDZ was discontinued specifically because of EIMs in 9.5% of patients.
 
  Almost one-third of patients had worsening EIMs after VDZ, which resulted in VDZ discontinuation in approximately 10% of patients. Previous biologic use or concurrent immunosuppressant or corticosteroid therapy did not predict EIM course after VDZ.

  There is strong evidence that social support-particularly perceived social support-functions as a protective factor for health. Few studies have investigated how medical students perceive the types of social support they experience.
 
  To determine how osteopathic medical students perceive social support, understand the factors that influence their perceptions, and explore how group participation in a cocurricular, academic program could affect student perceptions.
 
  In this cross-sectional study of 983 medical students at a multicampus osteopathic medical school in the Midwest, potential respondents were invited by email in March 2018 to participate in a self-reported evaluation of their perceived social support using a 40-question Interpersonal Support Evaluation List (ISEL). The demographic variables included gender, race, age, current phase in medical school, Hispanic heritage, campus assignment, and hometown population type. A total score for each type of social support and a summative score for overall it. Longitudinal studies following medical students over time would contribute to a more complete understanding of social support in medical students as they move from preclinical to the clinical phases of medical school.
 It is critical to understand the ways medical students experience social support and the factors that contribute to it. Longitudinal studies following medical students over time would contribute to a more complete understanding of social support in medical students as they move from preclinical to the clinical phases of medical school.Hydathodes are typically found at leaf teeth in vascular plants and are involved in water release to the outside. Although morphological and physiological analysis of hydathodes has been performed in various plants, little is known about the genes involved in hydathode function. In this study, we performed fluorescent protein-based imaging and tissue-specific RNA-seq analysis in Arabidopsis hydathodes. We used the enhancer trap line E325, which has been reported to express green fluorescent protein (GFP) at its hydathodes. We found that E325-GFP was expressed in small cells found inside the hydathodes (named E cells) that were distributed between the water pores and xylem ends. No fluorescence of the phloem markers pSUC2GFP and pSEOR1SEOR1-YFP was observed in the hydathodes. These observations indicate that Arabidopsis hydathodes are composed of three major components water pores, xylem ends, and E cells. In addition, we performed transcriptome analysis of the hydathode using the E325-GFP line. Microsamples were collected from GFP-positive or -negative regions of E325 leaf margins with a needle-based device (~130 µm in diameter). RNA-seq was performed with each single microsample using a high-throughput library preparation method called Lasy-Seq. We identified 72 differentially expressed genes. Among them, 68 genes showed significantly higher and four genes showed significantly lower expression in the hydathode. Our results provide new insights into the molecular basis for hydathode physiology and development.
  We report results of Years 2 and 3 of consecutive cluster-randomized controlled trials of trivalent inactivated influenza vaccine (IIV3) in Senegal.
 
  We cluster-randomized (11) 20 villages to annual vaccination with IIV3 or inactivated poliovirus vaccine (IPV) of age-eligible residents (6 months - 10 years). The primary outcome was total vaccine effectiveness against laboratory-confirmed influenza illness (LCI) among age-eligible children (modified-intention-to-treat population [mITT]). Secondary outcomes were indirect (herd protection) and population (overall community) vaccine effectiveness.
 
  We vaccinated 74% of 12,408 age-eligible children in Year 2 (June 2010-April 11) and 74% of 11,988 age-eligible children in Year 3 (April 2011-December 2011) with study vaccines. Annual cumulative incidence of LCI was 4.7 (Year 2) and 4.2 (Year 3) per 100 mITT child vaccinees of IPV villages.  https://www.selleckchem.com/products/sy-5609.html  In Year 2, IIV3 matched circulating influenza strains. The total effectiveness was 52.8% (95% CI 32.3%-67.0%), and the population effectiveness was 36.0% (95% CI 10.2%-54.4%) against LCI caused by any influenza strain. The indirect effectiveness against LCI by A/H3N2 was 56.4% (95% CI 39.0%-68.9%). In Year 3, 74% of influenza detections were vaccine-mismatched to circulating B/Yamagata and 24% were vaccine-matched to circulating A/H3N2. The Year 3 total effectiveness against LCI was -14.5% (95% CI -81.2%-27.6%). Vaccine effectiveness varied by type/subtype of influenza in both years.
 
  IIV3 was variably effective against influenza illness in Senegalese children, with total and indirect vaccine effectiveness present during the year when all circulating strains matched the IIV3 formulation.
