Impact of COVID-19 on Missouri 4-H State Fair Participation and Implications for Youth Development Programs
For University of Missouri Extension, facilitation of Missouri 4-H\u27s participation in the Missouri State Fair (MSF) during the COVID-19 era was a challenge and an opportunity for improvement. In a time when positive youth development experiences are more necessary than ever, Extension professionals must consider how to uphold the foundations of positive youth development and maintain a sense of program normalcy while ensuring new levels of safety and security. We describe lessons learned before, during, and after Missouri 4-H made the decision to open the MSF 4-H building in the midst of the 2020 COVID-19 pandemic and issue a call for related action by others
Vulvar Tuberculosis-A Rare Manifestation of the Disease
Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis. According to data from the World Health Organization, this disease remains one of the leading causes of death worldwide. Although it most commonly affects the lungs, tuberculosis can compromise any organ. The present study reports a rare case of vulvar tuberculosis in a postmenopausal woman with a history of asymptomatic pulmonary and pleural tuberculosis, with no prior documented contact with the bacillus. Diagnosis was based on vulvar lesion biopsies, with histological findings suggestive of infection and isolation of M. tuberculosis by microbiological culture and polymerase chain reaction (PCR) essays. The lesions reverted to normal after tuberculostatic therapy.info:eu-repo/semantics/publishedVersio
Guidance and Leakage properties of chiral optical fibers
The field theory of guided waves in optical fibers with step-index profiles and in which both core and cladding
are chiral isotropic media is developed. We show that both surface and semileaky modes can propagate in
optically active fibers. To shed light on the guidance and leakage properties of chiral isotropic fibers we
present a physical interpretation and several numerical results. The new leakage effect associated with semileaky
modes is an important property that cannot be neglected in the analysis of chiral optical fibers but that,
nevertheless, has been systematically disregarded in the literature

Following the Alphabet...For the Diagnosis of an Acute Hepatitis E: Case Report
Classicamente a hepatite viral está associada ao vírus da hepatite A, B ou C, podendo ser também causada por outros vírus. Apesar de não ser endémica em Portugal, reporta-se o caso esporádico de uma doente com hepatite aguda, cujo diagnóstico se confirmou hepatite E. Os autores chamam a atenção para uma causa rara de hepatite, devendo ser um diagnóstico a considerar após exclusão de causas mais frequentes.info:eu-repo/semantics/publishedVersio
Continuous Infusion of Piperacillin/Tazobactam in Septic Critically Ill Patients - a Multicenter Propensity Matched Analysis
The clinical efficacy of continuous infusion of piperacillin/tazobactam in critically ill patients with microbiologically documented infections is currently unknown. We conducted a retrospective multicenter cohort study in 7 Portuguese intensive care units (ICU). We included 569 critically ill adult patients with a documented infection and treated with piperacillin/tazobactam admitted to one of the participating ICU between 2006 and 2010. We successfully matched 173 pairs of patients according to whether they received continuous or conventional intermittent dosing of piperacillin/tazobactam, using a propensity score to adjust for confounding variables. The majority of patients received 16g/day of piperacillin plus 2g/day of tazobactam. The 28-day mortality rate was 28.3% in both groups (p = 1.0). The ICU and in-hospital mortality were also similar either in those receiving continuous infusion or intermittent dosing (23.7% vs. 20.2%, p = 0.512 and 41.6% vs. 40.5%, p = 0.913, respectively). In the subgroup of patients with a Simplified Acute Physiology Score (SAPS) II>42, the 28-day mortality rate was lower in the continuous infusion group (31.4% vs. 35.2%) although not reaching significance (p = 0.66). We concluded that the clinical efficacy of piperacillin/tazobactam in this heterogeneous group of critically ill patients infected with susceptible bacteria was independent of its mode of administration, either continuous infusion or intermittent dosing
