Predictive factors for Leishmania infantum infection in dogs examined at a veterinary teaching hospital in Teresina, State of Piauí, Brazil

Abstract: INTRODUCTION: In Brazil, culling of seropositive dogs is one of the recommended strategies to control visceral leishmaniasis. Since infectiousness is correlated with clinical signs, control measures targeting symptomatic dogs could be more effective. METHODS: A cross-sectional study was carried out among 1,410 dogs, predictive models were developed based on clinical signs and an indirect immunofluorescence antibody test. RESULTS: The validated predictive model showed sensitivity and specificity of 86.5% and 70.0%, respectively. CONCLUSIONS: Predictive models could be used as tools to aid control programs in focusing on a smaller fraction of dogs contributing more to infection dissemination.

This unit was provided for the PhD Program in Technology Assessment in 2015/2016.

Prevalence rates of infection in intensive care units of a tertiary teaching hospital

OBJECTIVE: To determine the prevalence rates of infections among intensive care unit patients, the predominant infecting organisms, and their resistance patterns. To identify the related factors for intensive care unit-acquired infection and mortality rates. DESIGN: A 1-day point-prevalence study. SETTING:A total of 19 intensive care units at the Hospital das Clínicas - University of São Paulo, School of Medicine (HC-FMUSP), a teaching and tertiary hospital, were eligible to participate in the study. PATIENTS: All patients over 16 years old occupying an intensive care unit bed over a 24-hour period. The 19 intensive care unit s provided 126 patient case reports. MAIN OUTCOME MEASURES: Rates of infection, antimicrobial use, microbiological isolates resistance patterns, potential related factors for intensive care unit-acquired infection, and death rates. RESULTS: A total of 126 patients were studied. Eighty-seven patients (69%) received antimicrobials on the day of study, 72 (57%) for treatment, and 15 (12%) for prophylaxis. Community-acquired infection occurred in 15 patients (20.8%), non- intensive care unit nosocomial infection in 24 (33.3%), and intensive care unit-acquired infection in 22 patients (30.6%). Eleven patients (15.3%) had no defined type. The most frequently reported infections were respiratory (58.5%). The most frequently isolated bacteria were Enterobacteriaceae (33.8%), Pseudomonas aeruginosa (26.4%), and Staphylococcus aureus (16.9%; [100% resistant to methicillin]). Multivariate regression analysis revealed 3 risk factors for intensive care unit-acquired infection: age > 60 years (p = 0.007), use of a nasogastric tube (p = 0.017), and postoperative status (p = 0.017). At the end of 4 weeks, overall mortality was 28.8%. Patients with infection had a mortality rate of 34.7%. There was no difference between mortality rates for infected and noninfected patients (p=0.088). CONCLUSION: The rate of nosocomial infection is high in intensive care unit patients, especially for respiratory infections. The predominant bacteria were Enterobacteriaceae, Pseudomonas aeruginosa, and Staphylococcus aureus (resistant organisms). Factors such as nasogastric intubation, postoperative status, and age ³60 years were significantly associated with infection. This study documents the clinical impression that prevalence rates of intensive care unit-acquired infections are high and suggests that preventive measures are important for reducing the occurrence of infection in critically ill patients.

Carl Icahn pushes ebay to spin-off paypal

The following case-study describes the situation involving eBay, PayPal and Carl Icahn as of February 2014. Its structure is divided between the narrative and a teaching note. The case narrative describes all the events between the three parties until the 24th of February 2014, when the activist investor Carl Icahn sends a public shareholder letter strongly criticizing eBay’s board and corporate governance practices while proposing at the same time the spin-off of PayPal from eBay. The teaching note intends to analyse the possibility of spinning-off PayPal, while at the same time analysing the Corporate Governance issues in eBay’s board. The final conclusion in the teaching note is favourable towards the spin-off of PayPal.

Garland, since 1776- a unique ownership structure

The case is based on Garland, a 240 years old Portuguese family business, now owned by the Dawson family. It focuses on a decision made 50 years ago, aligned with what had been the company’s history, about the ownership rules for family members, which influences the ownership structure of the firm. It addresses the main issues about ownership in family businesses, and tackles the problem of succession planning and fair process. It contains a teaching note to support the utilization of the case in a classroom context, with learning objectives, target audience, a teaching plan, questions and proposed answers, and theory that relates to the case. It is also complemented with an epilogue and an overview of the case.

Sistema de colocação de professores em Portugal: problemas e soluções

O sistema de colocação dos professores do ensino secundário em Portugal é um sistema centralizado, gerido pelo governo, mais precisamente pelo Ministério da Educação e Ciência. É um sistema que todos os anos apresenta problemas e, por esse motivo, é alvo de críticas por parte dos seus intervenientes, sobretudo pelos professores. Este artigo pretende identificar esses problemas, para isso efetuou-se uma revisão sistemática e uma meta análise de como é efetuada a colocação de professores em Portugal. Pretendeu-se ainda perceber e descrever como este sistema funciona na União Europeia. Para se encontrar soluções de melhoria para o sistema de colocação de professores efetuaram-se entrevistas a dirigentes escolares. Finalmente, a partir das soluções encontradas em países da União Europeia e das soluções oriundas das opiniões dos dirigentes escolares, são apresentados um conjunto de requisitos que o sistema de colocação de professores deve ter em atenção, de forma a evitar os problemas identificados.
