Prenatal syphilis and adverse pregnancy outcomes in women with HIV receiving ART in Brazil: a population-based study.
Lancet Reg Health Am
November 2024
Ministry of Health - Brazil, Department of Surveillance, Prevention and Control of STIs, AIDS, and Viral Hepatitis, SRTVN Quadra 701, Lote D, Edifício PO700 - 5º Andar, CEP: 70719-040, Brasília/DF, Brazil.
Background: We aimed to examine factors associated with prenatal syphilis, including prenatal care, and pregnancy outcomes of pregnant women with HIV in Brazil.
Methods: Retrospective data were gathered from a national cohort of Brazilian women with HIV on antiretroviral therapy who became pregnant between January 2015 and May 2018. Prenatal syphilis was defined by clinical diagnoses with treatment or any positive syphilis laboratory result between 30 days before conception and pregnancy conclusion.
Impact of crack cocaine on salivary nucleic acids, enzymes, esters, and lipids: A fourier-transform infrared spectroscopy study.
Heliyon
January 2025
Universidade Estadual Paulista (Unesp), Instituto de Ciência e Tecnologia, Câmpus de São José dos Campos, São Paulo, Brazil.
Objective: This study aims to analyze saliva composition in crack users using vibrational spectroscopy.
Material And Methods: A total of 90 participants were meticulously selected and divided into three groups, each comprising 30 individuals. All participants met the criterion of having no observable clinical changes in the oral mucosa.
Illicit drug use among adolescents and young adults with impairments in the US: A cross-sectional analysis of the National Survey on Drug Use And Health.

School of Sport Sciences, West Virginia University, Morgantown, WV, USA. Electronic address:
Objective: The purpose of this cross-sectional analysis is to compare the degree to which adolescents and adults with and without impairments in the US engage in illicit drug use.
Methods: This cross-sectional study utilized data from the 2022 National Survey of Drug Use and Health. Impairment status (mobility, cognitive, hearing, vision, self-care, and communication impairments), illicit drug use (cocaine, crack, heroin, hallucinogens, LSD, ecstasy and molly, inhalants, and methamphetamine), and demographic variables were measured using self-report.
Categorizing Stigma as a Barrier to Support Following Nonfatal Overdose: A Qualitative Study.
J Addict Med
January 2025
From the Boonshoft School of Medicine, Wright State University, Dayton, OH (KL, SS, TNC); Ohio State University, Columbus, OH (SH, NM, TP); and RTI International, Research Triangle Park, NC (BR).
Objectives: Stigma is known to be a major barrier to treatment for people who use drugs (PWUD). This study uses the Stigma and Health Discrimination Framework to analyze how different forms of stigma shape experiences in the wake of an overdose incident, and perceptions of the efficacy and utility of postoverdose interventions among a sample of PWUD in Dayton, Ohio-a location with a high overdose rate.
Methods: Interviews were conducted with 23 individuals who self-reported past-month illicit opioid, crack/cocaine, or methamphetamine use who had experienced or witnessed a drug overdose in the past 6 months.
Photonic platform coupled with machine learning algorithms to detect pyrolysis products of crack cocaine in saliva: A proof-of-concept animal study.

The non-invasive detection of crack/cocaine and other bioactive compounds from its pyrolysis in saliva can provide an alternative for drug analysis in forensic toxicology. Therefore, a highly sensitive, fast, reagent-free, and sustainable approach with a non-invasive specimen is relevant in public health. In this animal model study, we evaluated the effects of exposure to smoke crack cocaine on salivary flow, salivary gland weight, and salivary composition using Attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy.
