To determine the association between HIV infection and other risk factors for acute exacerbation of chronic obstructive pulmonary disease (AECOPD). ⋯ HIV infection, especially with lower CD4 cell count, is an independent risk factor for AECOPD. Enhanced susceptibility to harm from current smoking or unhealthy alcohol use in HIV-infected patients may also contribute to the greater rate of AECOPD.

Growing evidence demonstrates that a number of clinical disorders may be related to genetic defects in telomeres replication and extensions. Overall, these syndromes are referred to as telomeropathies or telomeres disorders or syndromes; they are increasingly being identified. In adulthood, idiopathic pulmonary fibrosis (IPF) is the most common symptom of telomeropathy. ⋯ In a cohort of patients addressed to lung transplantation, authors were able to demonstrate that subclinical bone marrow and liver abnormalities can be seen in patients with interstitial lung disease (ILD) and short telomeres, in some cases in the absence of clinically significant abnormalities in peripheral blood count and liver function tests. This observation sustains the rationale for further studies aimed to validate telomere length testing as a useful parameter as part of the evaluation for transplant candidacy. A deeper clarification of the complex link between IPF and short telomeres and telomeropathies is required for a new ILD classification, aimed to a fullpersonalized approach to the disease.

Interim Guidelines for Pregnant Women During a Zika Virus Outbreak - United States, 2016.
CDC has developed interim guidelines for health care providers in the United States caring for pregnant women during a Zika virus outbreak. These guidelines include recommendations for pregnant women considering travel to an area with Zika virus transmission and recommendations for screening, testing, and management of pregnant returning travelers. Updates on areas with ongoing Zika virus transmission are available online (http://wwwnc.cdc.gov/travel/notices/). ⋯ Testing is not indicated for women without a travel history to an area with Zika virus transmission. In pregnant women with laboratory evidence of Zika virus infection, serial ultrasound examination should be considered to monitor fetal growth and anatomy and referral to a maternal-fetal medicine or infectious disease specialist with expertise in pregnancy management is recommended. There is no specific antiviral treatment for Zika virus; supportive care is recommended.

Observational Study
Perioperative and Anesthesia-Related Mortality: An 8-Year Observational Survey From a Tertiary Teaching Hospital.
In 2006, a previous study at our institution reported high perioperative and anesthesia-related mortality rates of 21.97 and 1.12 per 10,000 anesthetics, respectively. Since then, changes in surgical practices may have decreased these rates. However, the actual perioperative and anesthesia-related mortality rates in Brazil remains unknown. ⋯ There were no anesthesia-related deaths. However, the high mortality rate caused by the poor physical conditions of some patients suggests that primary prevention might be the key to reducing perioperative mortality. These findings demonstrate the need to improve medical perioperative practices for high-risk patients in under-resourced settings.

Since the initial reports of a link between Zika and microcephaly, researchers across the world began working toward understanding the virus. In a short amount of time, Zika has become a household name, prompting worldwide concern. ⋯ We currently do not have a vaccine for Zika. But with the recent findings, vaccine companies are mobilizing their resources to expedite efforts to shave years off the typical decade-long process of vaccine development.
