Objective: To determine the prevalence and epidemiological characteristics of inmates diagnosed with infectious diseases living in a region with a high number of prisons, São Paulo, Brazil.
Design: This is a retrospective and descriptive study conducted from November 2017 to October 2018.
Setting: Prisons located in the western and northwestern regions of São Paulo, Brazil.
Methods: We conducted a retrospective analysis on infectious diseases and coinfections (HIV, hepatitis B virus (HBV), hepatitis C virus (HCV), syphilis and tuberculosis (TB)) of inmates from 28 prisons. Inmates were previously diagnosed following the protocol for control and surveillance of infectious diseases, through laboratory or imaging methods. A questionnaire was completed by the healthcare staff. Prevalence was obtained by dividing the number of individuals with positive results by the number of inmates in each prison. Locations of prisons were obtained and maps were constructed using geographic information systems.
Results: A total of 741 of 37 497 inmates (1.97%) were diagnosed with HIV, HBV, HCV, syphilis or TB. HIV was the most prevalent infectious disease (0.68%), followed by TB (0.66%), syphilis (0.2%), HCV (0.2%) and HBV (0.04%). For all of these diseases, prevalence rates varied from very low to high (3.11% and 2.45%) for TB and HIV, respectively, in the five prisons where they were most prevalent. HIV-syphilis was the most associated coinfection (OR, 63.7; 95% CI 41.4 to 96.7). Three of those diagnosed with the infection were female and the ratio of female to men was 0.004:1.
Conclusions: Our findings demonstrate that the number of cases of infectious disease among inmates in the northwestern and western region of São Paulo is probably underestimated, with lower rates of HCV, HBV and syphilis. This represents a challenge to prisoners' health. Improvements in diagnosis, mainly to reduce viral hepatitis, are crucial with benefits for inmates and the general population.

Prognostic significance of serum complement activation, neutrophil extracellular traps and extracellular DNA in newly diagnosed epithelial ovarian cancer.

Purpose: We observed that the tumor microenvironment (TME) in metastatic epithelial ovarian cancer (EOC) and in other solid tumors can reprogram normal neutrophils to acquire a complement-dependent suppressor phenotype characterized by inhibition of stimulated T cell activation. This study aims to evaluate whether serum markers of neutrophil activation and complement at diagnosis of EOC would be associated with clinical outcomes.
Experimental Design: We conducted a two-center prospective study of patients with newly diagnosed EOC (N = 188).
West Nile Neuroinvasive Disease: Case Series and Review of the Literature.

Department of Medicine, Long Island Jewish Forest Hills (Northwell Health), Forest Hills, NY.
Background: West Nile virus (WNV), although underdiagnosed, is the most common mosquito-borne disease and the second most common cause of viral encephalitis in the United States. Fewer than 1% of those infected develop neuroinvasive disease.
Methods: We present a cluster of 3 cases of neuroinvasive WNV that occurred between August and September 2023 and a review of the literature for neurologic involvement with this virus.

The Spanish Society of Pneumology and Thoracic Surgery (SEPAR) and the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC) have developed together Clinical Practice Guidelines (GPC) on the management of people affected by tuberculosis (TB) resistant to drugs with activity against Mycobacterium tuberculosis. These clinical practice guidelines include the latest updates of the SEPAR regulations for the diagnosis and treatment of drug-resistant TB from 2017 and 2020 as the starting point. The methodology included asking relevant clinical questions based on PICO methodology, a literature search focusing on each question, and a systematic and comprehensive evaluation of the evidence, with a summary of this evidence for each question.

Objective: To examine the impact of in utero exposure to dolutegravir (DTG)- or efavirenz (EFV)-based antiretroviral treatment (ART) on child neurodevelopmental (ND) outcomes.
Design: Prospective cohort design, enrolling 3 cohorts of 2-year-olds: children HIV-negative born to mothers with HIV (CHEU) receiving either DTG-based or EFV-based 3-drug ART during pregnancy, and children born to mothers without HIV (CHUU).
Methods: Primary child ND outcomes were assessed using the Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III) and compared between cohorts using generalized estimating equation models adjusted for confounders.
Prevalence and incidence of HPV-related dysplasia of oropharyngeal, cervical, and anal mucosae in Spanish people living with HIV (PLHIV).
AIDS

Internal Medicine Department, Hospital Universitario Virgen de las Nieves, Instituto de Investigación Biosanitario de Granada (IBS-Granada), Spain.
Background: Objectives were to determine the prevalence/incidence of HPV-related dysplasia and clearance/acquisition rates of high-risk HPV (HR-HPV) genotypes in genital mucosa of women-LHIV and oropharyngeal and anal mucosa of PLHIV and to evaluate factors related to HR-HPV infection in oropharyngeal mucosa at 12-months.
Material And Methods: Prospective, longitudinal study with 12-month follow-up, enrolled PLHIV between December 2022 and April 2023. At baseline and 12-months, HIV-related clinical and analytical variables were recorded, oropharyngeal mucosa exudates were taken for polymerase chain reaction (PCR) studies for HPV and other sexually transmitted infections, while anal and female genital samples were self-sampled for HPV detection and genotyping by PCR and thin-layer cytology.
