In a study to evaluate knowledge, attitudes, and sex behaviors in an occupation that facilitates high HIV transmission globally, 71 Bolivian truck drivers participated in a multiple method needs assessment, in four phases. In all phases, majority of truckers reported contact with casual sex partners. Fifty-two percent of truckers in the qualitative phases reported having had a sexually transmitted infection (STI) and 27% indicated having anal sex with female partners. These data, combined with truckers demonstrating inconsistent STI/HIV knowledge and condom use, place Bolivian truck drivers and their spouses at risk for HIV/AIDS. Government and non-governmental organizations need to increase efforts to include this population in prevention programs. [ABSTRACT FROM AUTHOR]

The effect of missing data can result in errors that exhibit temporal and spatial patterns in climatological and meteorological research applications. Many climate related tools perform best with a serially complete dataset (SCD). To support the National Agricultural Decision Support System (NADSS), a SCD with no missing data values for daily temperature and precipitation for the United States was developed using a self-calibrating data quality control (QC) library. The library performs two primary functions: identifies outliers and provides estimates to replace missing data values and outliers. This study presents the development of the SCD and the QC library in detail. An in-depth evaluation in terms of root mean square error (RMSE) and mean absolute error (MAE) for the SCD for the period of 1975 - 2004 is provided. The study shows an impressively low average RMSE in the range of 2.27 to 3.58°F for temperature and 0.07 to 0.23 inch for precipitation for the whole country for 30 years. The goal of this study is to enhance drought risk assessment and environmental risk analysis. [ABSTRACT FROM AUTHOR]

Previous work that compared male and female reports of women's heterosexual initiation and aggression is replicated. It was hypothesized that men's reports of women's sexual initiation and aggression would be significantly greater than women's self-report of sexual initiation and aggression in the most recent sample. Of the 24 questionnaire items, 12 of the 17 specifically designed to assess sexual initiation or aggression demonstrated significant reporting differences. For every questionnaire item, except "mutually consenting contact," men reported women initiating sexual contact more often than women self-reported. In addition, comparisons were made to determine the level of agreement between the results of this study and a previous study in which the same comparisons were made with a different sample. It was hypothesized that the identical questionnaire items would demonstrate significant gender-based reporting differences in both samples. This hypothesis was mostly supported with 11 items showing a significant difference in both samples. In both samples, males reported receiving female initiation and aggression more frequently than females reported giving. Logistic regression results supported a difference in perception of women's sexual initiation based on gender of respondent. In both samples men see women's initiation as less conforming to traditional social norms for women and more aggressive than women do. Gender role expectations and social desirability may influence male and female perceptions of female heterosexual initiation and aggression in a way that contributes to significant differences in reporting.

The purpose of this study was to determine the relationship between educational level and time of decline to AIDS mortality. A total of 1578 death certificates were matched and processed with reported Louisiana male AIDS cases to assess the relation between decline to AIDS mortality with educational background, age, race, and transmission group. A 2 (race) x 4 (age group) x 2 (transmission group) x 3 (educational background) ANOVA was performed. In addition, descriptive statistics were utilized to show patterns of the association. A significant (P < 0.05) main effect of educational background on decline to death was found. However, inconsistent educational level effect on mortality was found across different subgroups regarding race and AIDS transmission group. Those with higher educational levels demonstrated least severity of decline to death. Furthermore, a significant 3-way interaction in the well-educated black intravenous drug user (IDU) population suggests a call to expand current models of counselling for this clientele.

The influences of public policies fighting HIV among women who have sex with women is scarcely studied. This study aimed to analyse the time series of human immunodeficiency virus (HIV) epidemic, between 2007 and 2020, among Brazilian women who have sex with women, in order to evaluate the effect of Brazilian policies for fighting HIV in this subpopulation compared to women who have sex with men (WSM). This ecological study employed HIV and acquired immunodeficiency syndrome (AIDS) new cases among women who have sex strictly with women (WSW), women who have sex with men and women (WSMW), and WSM reported to the Sistema de Informação de Agravos de Notificação from 2007 to 2020. Crude Brazilian and regional annual age-adjusted HIV/AIDS population-level incidence rates were calculated for WSW, WSMW and WSM. The rates were then analyzed using the Joinpoint regression model. A total of 102,890, 757, and 1,699 notifications of WSW, WSMW, and WSM living with HIV/AIDS were reported during the study period, respectively. South Brazilian region had the greatest HIV/AIDS incidence rates among WSM and bisexual women while the North region had the greatest incidence among WSW. In the WSM population, the temporal trends showed at least one stable or an increasing trend period from 2007 to 2013 or 2014, followed by one decreasing trend in all Brazilian regions. While among the WSMW most of the regions had a stable trend period from 2007 to 2020, in WSW group most of the trends had only one decreasing period. The decreasing trends were faster in WSM than in WSW. These results suggest a low efficiency of Brazilian policies for fighting HIV among WSW and WSMW and show the necessity of implementing new policies specific to this population., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Bezerra, Sorensen, Rodrigues, Sousa, Carneiro, Polaro, Ramos, Ferreira, Gir, Reis and Botelho.)

Objective: To analysis the epidemiological scenery of the congenital syphilis (CS) in Brazil employing spatial analysis techniques., Design: Ecological study., Settings: This study was conducted in Brazil SAMPLE: A total of 151 601 CS cases notified to the Diseases and Notification Information System from 2007 to 2018 from children aged 0-23 months and born from mothers living in Brazil were included in this study., Primary Outcome Measures: The CS incidence rates were calculated by triad (2007-2010, 2011-2014 and 2015-2018) for all Brazilian municipalities following the Boxcox transformation to remove the discrepant values. The transformed rates were analysed through the spatial autocorrelation of Moran, Kernel density estimative and spatial scan., Results: From 2007 to 2018, the CS incidence rates increased in all Brazilian regions. The CS spread towards the interior of Brazil, and a higher expansion was noticed between 2015 and 2018. The municipalities that were greatly affected by the CS were those having a high migration of people, such as the ones bordering other countries and the touristic cities. Recife, Campo Grande, Rio de Janeiro, Porto Alegre and Manaus were the capitals with the greatest spatial and spatiotemporal risk., Conclusion: This study provides assistance to health authorities to fight CS in Brazil. More investment is necessary in prenatal care quality focusing on pregnant women and their partners to guarantee their full access to preventive resources against sexually transmitted infections., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Background: The COVID-19 pandemic is one of the biggest health crises in the world and the use of personal protective equipment (PPE) is significant measures to prevent the transmission of SARS-CoV-2. However, PPE needs to be used properly by healthcare professionals., Objective: To analyze the use of PPE among Brazilian health professionals and associated factors during a period of the COVID-19 pandemic., Methods: An analytical cross-sectional study was carried out from October to December 2020. For data collection, the respondent-driven sampling technique was used, adapted for social media, with a link to an online survey form., Results: The study considered 12,086 Brazilian health professionals. Most (69%) used PPE recommended for the care of patients with suspected or diagnosed COVID-19. Factors associated with the use of PPE were: working in an Intensive Care Unit (ICU) or in a field hospital, receiving training, being provided with sufficient, high-quality PPE by the workplace and being an odontologist compared to nursing professionals. For procedures that generate aerosols in the context of COVID-19, 54.1% of them used the recommended PPE, the associated factors were: being married or in a stable relationship compared to a single/divorced professional, working in an ICU, being offered training, providing sufficient, high-quality PPE, and being an odontologist compared to nursing professionals., Conclusions: For the care of patients with COVID-19, 69% of health professionals used PPE properly, and several factors interfered with the use of this equipment.

The objective of this study was to identify the factors associated with the non-disclosure of HIV seropositivity among people living with HIV/AIDS undergoing antiretroviral treatment. A cross-sectional study was carried out in five HIV clinics in the interior of the state of São Paulo, Brazil. Logistic regression analysis was used to determine independent predictors of HIV status disclosure. It was found that 68.5% revealed their HIV seropositivity to their most recent sexual partner. The variables "casual partner" [OR 19.08, 95% CI (4.08, 20.23), p = 0.001], "sexual partners with negative HIV or unknown HIV" [OR 4.54, 95% CI (1.58, 1.01), p = 0.005], "multiple sexual partners" [OR = 3.17, 95% CI (1.34, 7.35), p = 0.009], and "lack of communication with the partner on HIV prevention"[OR = 8.3, 95% CI (3.88, 16.61), p = 0.001] were independently associated with non-disclosure of the diagnosis. Future HIV prevention interventions should encourage open communication between sexual partners., (© 2021.

Background: After HIV diagnosis, people maintain, reestablish their sexual lives, or build new relationships, often with HIV seronegative partners. Therefore, understanding the factors concerning couple-vulnerability is essential in order to design effective HIV preventive strategies. We examined HIV serodiscordant couples prevalence and their associated factors from a Brazilian city., Methods: This is a cross-sectional analytical study carried out with people living with HIV (PLHIV) who had an active sex life and were engagement in HIV health care follow-up. Data were collected using a semi-structured questionnaire during individual interviews. We analyzed data using bivariate and multiple logistic regression analyses., Results: There was 72.0% of HIV serodiscordant partnerships. Those who inconsistently used condoms (aOR: 0.3[0.13-0.7]) and/or had HIV detectable viral load (aOR: 0.29 [0.12-0.7]) were less likely to have an HIV serodiscordant sexual partner. On other hand, the lack of HIV transmission counseling by the health service (aOR: 5.08 [2.02-12.76]), or those who had a casual partner (aOR: 8.12 [1.7-38.8]) or a steady and casual one concomitantly (aOR: 24.82 [1.46-420.83]), were more likely to indicate an HIV serodiscordant partnership., Conclusion: The findings showed a high prevalence of serodiscordant partnerships in PLHIV. Greater visibility among couples in the health services is needed as well as a reassessment in order to provide PLHIV and their sexual partners with care strategies, by the health professionals., (© 2021.
