RESUMO

INTRODUCTION: Tuberculosis is a major cause of mortality worldwide. Prisoners in Guiana have multiple risk factors. The primary objective of this study was to describe tuberculosis occurring in prison and after release in French Guiana between 2008 and 2020. Secondary objectives were to identify tuberculosis risk factors and determine annual incidences. METHODS: A retrospective cohort study of tuberculosis cases was carried out at the Guiana prison between 2008 and 2020. Data were collected from prison registers and cross-referenced with the list of tuberculosis notifications in French Guiana. RESULTS: A total of 36 cases of tuberculosis were studied. Incidence was high, at 263/100,000 per year, higher than elsewhere in France and comparable to that in Brazil. Despite visibly effective screening on entry, with little evidence of intra-prison circulation of tuberculosis, 39% of patients were diagnosed within two years of leaving prison (76% were symptomatic). This could be explained by the high prevalence of latent forms (LTI). DISCUSSION: Continued screening on entry, in combination with annual radiological and clinical screening, and reinforced follow-up on release seem indicated to improve patient management and the search for possible LTI.

RESUMO

Q fever is a major public health problem in French Guiana. In recent years, a considerable number of cases has been reported in French Guiana's penitentiary center. The main objective of this study was to describe the epidemiology of these cases. A retrospective study was conducted at the prison to identify cases of acute Q fever in people incarcerated between 2010 and 2021. During the study period, 16 patients were diagnosed with acute Q fever. The positivity rate varied between 13 and 57%. The annual incidence rate in 2019, 2020 and 2021 was 269 (95% CI: 0-640) 1,120 (95% CI: 290-1950) and 1,931 (95% CI: 60-3810) per 100,000 person-years, respectively. While several vertebrate species have already been shown to play an important role in the transmission of Coxiella burnetii, the full epidemiology picture in the tropics is far from clear, and the prison context, with its controlled environment, could help provide answers.

RESUMO

PURPOSE: Incarcerated women are a vulnerable population in terms of sexual and reproductive health. In French Guiana, most incarcerated women come from unsafe environments and are incarcerated because of drug trafficking. Medical follow-up processes used in prison (medical assessment on arrival, and then two half-days per week upon request but without an obstetrician-gynecologist) does not allow for a thorough assessment of the impact of incarceration on women prisoners' health to take place. In the absence of data, the purpose of this study was to describe incarcerated women's experiences in relation to sexual and reproductive health. DESIGN/METHODOLOGY/APPROACH: Semi-structured interviews were conducted among French-speaking adult women who had been incarcerated for at least four months in a French Guianan prison. Menstruation, contraception, pregnancy, abortion, sexually transmitted infections and sexuality were described by means of interpretative phenomenological analysis. FINDINGS: A total of 14 women were interviewed. They suffered from menstrual cycle disorders, poor hygiene and menstrual insecurity. They appeared to have emotionally disinvested sexuality. However, intra-prison sexual activity existed for some (masturbation, conjugal prison visits, homosexual intercourse between fellow prisoners). Homosexual relations were a source of discrimination. Being pregnant while incarcerated was viewed negatively. A lack of knowledge about sexual and reproductive health and high-risk behaviors such as piercing and tattooing practices were widespread. ORIGINALITY/VALUE: Incarceration is a vulnerable time for women's sexual and reproductive health. Sexual activity exposes women to risks and discrimination that should be taken into account in a multidisciplinary approach adapted to the prison environment.

RESUMO

Crotamine is a basic, 42-residue polypeptide from snake venom that has been shown to possess cell-penetrating properties. Here we describe the preparation, purification, biochemical and biophysical analysis of venom-derived, recombinant, chemically synthesized, and fluorescent-labeled crotamine. We also describe the formation and characterization of crotamine-DNA and crotamine-RNA nanoparticles; and the delivery of these nanoparticles into cells and animals. Crotamine forms nanoparticles with a variety of DNA and RNA molecules, and crotamine-plasmid DNA nanoparticles are selectively delivered into actively proliferating cells in culture or in living organisms such as mice, Plasmodium, and worms. As such, these nanoparticles could form the basis for a nucleic acid drug-delivery system. We also describe here the design and characterization of crotamine-functionalized gold nanoparticles, and the delivery of these nanoparticles into cells. We also evaluated the viability of using the combination of crotamine with silica nanoparticles in animal models, aiming to provide slow delivery, and to decrease the crotamine doses needed for the biological effects. In addition, the efficacy of administering crotamine orally was also demonstrated.

RESUMO

Human T-cell lymphotropic virus type I (HTLV-I) proviral integration status was examined by Southern blot analysis in peripheral blood mononuclear cell (PBMC) DNA from patients presenting a tropical spastic paraparesis (TSP) and serological evidence of HTLV-I infection. Surface phenotype and morphological aspects of PBMC were also studied. A polyclonal HTLV-I proviral integration was found in the PBMC of the 10 patients studied irrespective of their geographical origin (French West Indies, French Guiana, and Africa), the duration of their clincal illness, or the HTLV-I antibody titer. Furthermore, by dilution experiments and hypothesizing that only one copy of HTLV-I proviral DNA is present in one call, we estimated that this HTLV-I integration is present in 3 percent to 15 percent of their PBMC. All 10 TSP/HTLV-I patients studied had an average of 10 percent of thier lymphocytes abnormal, presening either a misshapen nucleus or an adult T-cell leukemia/lymphoma(ATL)-like feature. Moreover, an elevated CD4/CD8 ratio associated with the presence of activated T cells with a high level of DR expression was observed in most patients. The significant frequency of viral-positive PBMC and the important load of HTLV-I proviral DNA that we observed in TSP/HTLV-I patients might play an important role in the pathogenesis of this recently identified clinico-virological entity.
