Aim: To analyze the incidence and risk factors for retinopathy of prematurity (ROP).

Methods: A retrospective analysis was conducted on 568 premature infants from September 2005 to December 2010 with birth weight(BW) equal to or less than 2 500g or a gestational age(GA) at birth of 34 weeks or less. All of the members were examined by indirect binocular ophthalmoscopy.

Results: ROP occurred with an incidence rate of 10.7% among 568 premature infants, and stages 3 and above ROP occurred with an incidence rate of 2.5%. This study showed the infants were more prone to develop ROP with short geststional age, low BW, long time of oxygen inhalation, and severe infants diseases. Twins had a significantly higher rate of ROP(18.3%) than singleton babies(9.8%), ROP were severer in twins than singleton babies.

Conclusion: Short GA, low BW, long time of oxygen inhalation, severe infants diseases, and non-singleton babies were the most significant risk factors associated with ROP.

Posttraumatic Stress Disorder Is Associated With Endothelial Dysfunction in Women With HIV.

Department of Psychiatry and Behavioral Sciences, Emory University, Atlanta, Georgia, USA. Electronic address:

Background: HIV induced endothelial dysfunction (ED) contributes to cardiovascular disease (CVD) in women with HIV (WWH). Although psychosocial stress has been implicated in the development of CVD in HIV, its impact on ED in WWH remains unknown.

Objectives: The authors hypothesized that posttraumatic stress disorder (PTSD) and HIV interact to contribute to ED in WWH.

Individuals with severe mental illness (SMI) have a shorter life expectancy compared to the general population, largely due to cardiovascular disease (CVD). In this report from the Fixed Dose Intervention Trial of New England Enhancing Survival in SMI Patients (FITNESS), we examined baseline CVD risk factors and their treatment in patients with SMI and second generation antipsychotic (SGA) use. FITNESS enrolled 204 participants with SMI and SGA use, but without documented history of CVD or diabetes mellitus, from several clinics in the Boston, Massachusetts, area between April 29, 2015, and September 26, 2019.

Introduction: LDL-cholesterol greater than 190 mg/dL indicates severe hypercholesterolemia (HS) of monogenic and/or polygenic origin. Genetic risk scores (GRS) evaluate potential polygenic causes.

Objective: we applied a GRS of 6-SNP (GRS-6) in HS individuals.

Cardiovascular disease is the main cause of mortality in Mexico as well as the rest of the world, with dyslipidemia being one of the main risk factors. Despite the importance of its epidemiological impact, there is still -among primary care physicians- a lack of knowledge ranging from the basic concepts for diagnosis to the most recent recommendations for treatment. This document consisting of 10 questions is done by experts in this field.

Progressive supranuclear palsy: an updated approach on diagnosis, treatment, risk factors and outlook in Mexico.

Progressive supranuclear palsy (PSP) is a rare, atypical parkinsonism, characterized by the presence of intracerebral tau protein aggregates and determined by a wide spectrum of clinical features. The definitive diagnosis is postmortem and is identified through the presence of neuronal death, gliosis, and aggregates of the tau protein presented in the form of neurofibrillary tangles (MNF) with a globose appearance in regions such as the subthalamic nucleus, the substantia nigra, and the globus pallidus The findings in ancillary imaging studies, as well as fluids biomarkers, are not sufficient to support diagnosis of PSP but are used to rule out similar pathologies because there are still no specific or validated biomarkers for this disease. The current treatment of PSP is focused on reducing symptoms, although emerging therapies seek to counteract its pathophysiological mechanisms.
