Background: Although systemic chemotherapy is inevitably selected as the modality of treatment for high-grade bone and soft tissue sarcoma (BSTS), limited information is available regarding febrile neutropenia (FN).

Patients And Methods: FN incidence, blood culture results and risk factors were analyzed in 35 patients with high-grade BSTS.

Results: FN occurred in 51% of the patients and 24% of the courses of systemic chemotherapy. Culture results indicated pathogen in only 33.3% of patients who had FN. Methicillin-resistant Staphylococcus epidermidis and methicillin-resistant Staphylococcus aureus were frequently observed. Body weight of less than 61.0 kg and a tumor originating from the bone in a patient-based analysis, and serum albumin <4.2 g/dl and having a source of infection in a course-based analysis were independent risk factors for FN.

Conclusion: Considerably high risks for FN during chemotherapy for BSTS were confirmed. The risk factors presented here appeared to differ from those in previously reported guidelines.

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.

Gac Med Mex

January 2025

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.
