Induced abortion incidence and associated factors in a cohort of women living with HIV in Rio De Janeiro, Brazil, 1996-2016.

Background: Abortion is a public health problem in Latin America and is more common among women living with HIV.

Objective: to verify the incidence and factors associated with induced abortion in a cohort of women living with HIV assisted in a reference service for care for individuals with HIV/AIDS in Rio de Janeiro/Brazil.

Methods: Prospective cohort during the period 1996-2016.

Model Based System Engineering (MBSE) and design assurance process in the context of mitigation of design errors during the development of highly integrated and complex aerospace systems.

Over the years, aircraft and spacecraft designs incorporated highly integrated and/or complex systems that can manage complex scenarios during its operation. In addition to the inherent complexity and/or high level of integration of those systems, the development process applied to aerospace programs is also challenged by other factors: program schedule, budget, multidisciplinary teams, new industry emerging technologies, large number of different processes and procedures that guide the activities along the development life cycle, and others. Given the fact many tasks executed during the development of such systems require human interaction, that yields the introduction of design errors that can contribute to the occurrence of non-desired system behaviors during operation phase.

Pregnancy incidence, outcomes and associated factors in a cohort of women living with HIV/AIDS in Rio de Janeiro, Brazil, 1996-2016.

The aim of this research was to analyze pregnancy incidence and associated factors in a cohort of 753 women living with HIV/AIDS (WLWHA) in Rio de Janeiro, Brazil, from 1996 to 2016. Women aged 18-49 years who were not on menopause (surgical or natural) and did not have a tubal ligation were eligible for the study. Data were collected by medical professionals during initial and follow-up visits.

Serology for visceral leishmaniasis: How trusty is the accuracy reported by the manufacturers?

Timely and accurate diagnosis is one of the strategies for managing visceral leishmaniasis (VL). Given the specificities of this infection, which affects different vulnerable populations, the local assessment of the accuracy of the available diagnostic test is a requirement for the good use of resources. In Brazil, performance data are required for test registration with the National Regulatory Agency (ANVISA), but there are no minimum requirements established for performance evaluation.
