Chemsex among men who have sex with men during the Mpox health crisis in Brazil: A nationwide web survey.

OBJECTIVE: To understand the factors associated with the practice of chemsex among MSM in Brazil, especially during the Mpox health crisis, and to design effective prevention and intervention strategies specifically for this population. DESIGN: A cross-sectional and analytical study using an electronic survey, conducted from September to December 2022, during the peak of the Mpox outbreak in Brazil. SAMPLE: A total of 1452 MSM aged 18 and older. MEASUREMENTS: Data were collected via the REDCap platform through a survey with 46 questions. These addressed demographic data, sexual affiliations, practices, experiences with Mpox, healthcare service usage, and stigma or fear related to Mpox. RESULTS: The prevalence of chemsex was 19.42% (n = 282). Multivariate Poisson modeling indicated a high incidence of chemsex among those diagnosed with Mpox and those involved in high-risk behaviors. The practice of chemsex was six times higher among those diagnosed with Mpox (95% CI: 4.73-9.10). MSM who engage in bugchasing had a prevalence twice that of the main outcome (95% CI: 1.31-3.16). CONCLUSION: There is a significant need for targeted interventions for MSM in Brazil, especially given the Mpox outbreak. This study highlights the strong relationships between chemsex, experiences with Mpox, and various sexual behaviors, underscoring the importance of effective public health initiatives.

Safety and efficacy of silicone tape for indwelling urinary catheter fixation in intensive care patients-A randomized clinical trial.

BACKGROUND: Critically ill patients are more vulnerable to medical adhesive-related skin injuries (MARSI), whose prevention is a constant challenge and one of the main quality indicators of nursing care. MARSI associated with indwelling urinary catheter (IUC) fixation is a relevant adverse event, mainly because of the constant involuntary traction and high skin vulnerability of the fixation site. Silicone adhesive tape has appreciable qualities for fragile skin among the range of adhesives, leading to the inference that it reduces the risk of MARSI. AIM: To compare silicone adhesive tape for IUC fixation with acrylate tape regarding its safety and efficacy. STUDY DESIGN: This was a randomized controlled trial blinded to the patients and evaluator. Data were collected from an intensive care unit (ICU) of a tertiary university hospital in Brazil. Patients with IUC and no MARSI at the fixation site were considered eligible. The omega (Ω) fixation technique was used for IUC fixation. A total of 132 participants were enrolled and divided into two research groups: 66 patients in the intervention group (silicone tape) and 66 in the control group (acrylate tape). Outcomes were the incidence of MARSI, patient outcome in the ICU and hospital and partial, total and overall spontaneous detachment of the tapes. RESULTS: The overall incidence of MARSI was 28%, with 21% in the silicone group and 35% in the acrylate group, with no statistically significant difference (p = .121), including the severity of the lesions (p = .902). However, partial (p = .003) and overall (p < .001) detachment of the tapes were more frequent in the silicone group. CONCLUSIONS: Silicone tape is no safer than acrylate tape for IUC fixation and is less adhesively effective. RELEVANCE TO CLINICAL PRACTICE: There is no evidence to support the extensive use of silicone tape in this context.

HIV testing among immigrant men who have sex with men in Brazil.

OBJECTIVE: To evaluate the prevalence of non-testing for HIV among immigrant men who have sex with men (MSM) residing in Brazil and identify associated factors. DESIGN: An analytical web-survey study was conducted across all Brazilian states from January 2020 to May 2021. SAMPLE: The study included 804 MSM immigrants from Portuguese-speaking countries. MEASUREMENTS: Odds ratio (OR) and adjusted Odds Ratio (AOR) were utilized to determine the strength of the association between non-HIV testing and associated factors. RESULTS: Among the participants, 63.7% had never undergone HIV testing. Multivariate analysis revealed several factors associated with a higher likelihood of not being tested for HIV: having a steady/monogamus partner (AOR: 1.5; 95%CI: 1.1-2.3) or both casual and steady partners (AOR: 1.8; 95%CI: 1.2-3.4), not engaging in bareback sex (AOR: 1.91; 95%CI: 3-3.5), being an immigrant in the country for less than 12 months (AOR: 3.7; 95%CI: 2.5-9.7), and having a preference for insertive (AOR: 1.5; 95%CI: 1.1-2.5) or receptive (AOR: 2.9; 95%CI: 1.4-5.7) roles. However, practicing chemsex was found to be a protective factor for testing (AOR: 4). CONCLUSION: To enhance HIV prevention strategies, it is crucial to implement specific measures that ensure accessibility, confidentiality, and a reduction in stigma associated with HIV testing.

Alignment and contribution of nursing doctoral programs to achieve the sustainable development goals.

BACKGROUND: Different social segments from several regions of the world face challenges in order to achieve the sustainable development goals (SDGs). Nursing represents the greatest number of health workforce in the globe, dealing with these challenges in different paths, among them the training of human resources. In this context, the goal of this study was to compare the relationship between the objectives and research areas underlying nursing doctoral programs in Latin America and the SDGs. METHOD: Documental research comparing data of all Latin American nursing doctoral programs and the SDGs, conducted between January and March 2020. RESULTS: From the total of 56 existing programs in Latin America, this study analyzed 52 of them, representing 92.8% of the total. Most nursing doctoral programs have contributed to SDG 3, in addition to goals 1, 2, 4, 5, 6, 8, 9, 10, 12 and 16. The SDGs 11, 13, 14, 15 and 17 were not related to any of the analyzed programs. Data reveal that the training of nursing PhDs is essential to fulfilling these goals. Results also indicate a need of programs to remain committed to relationships that enhance nursing skills to cope with the current challenges in terms of global health, such as investments for the reduction of social and gender inequities. CONCLUSION: The doctoral training of nurses in Latin America needs to be better aligned with the sustainable development goals (SDGs), since there is a high concentration in SDG 3. We believe that nursing will bring a greater contribution to the movement to protect planetary health as the principles governing nursing practices are better aligned with international health demands and agendas.

Broad Diversity of Fungi in Hospital Water.

INTRODUCTION: Some studies have reported the occurrence of microorganisms isolated from water. Considering these microorganisms, fungi are known to occur ubiquitously in the environment, including water, and some are pathogenic and may cause health problems, especially in immunocompromised individuals. The aim of this study was to identify fungi in hospital water samples and to correlate their presence with the concentration of free residual chlorine. METHODS: Water samples (100 mL) were collected from taps (n = 74) and water purifiers (n = 14) in different locations in a university hospital. Samples were filtered through a nitrocellulose membrane and placed on Sabouraud dextrose agar and incubated for 24 hours at 30°C. Fungi were identified according to established methods based on macroscopic and microscopic characteristics (filamentous) and physiological tests (yeasts). Free chlorine residual content was measured at the time of sample collection. RESULTS: Seventy species of fungi were identified in the water samples and about 56% of the water samples contained culturable fungi. Cladosporium oxysporum, Penicillium spinulosum, and Aspergillus fumigatus were the most common filamentous fungi. Aureobasidium pullulans and Candida parapsilosis were the most common yeasts. Chemical analyses revealed that free residual chlorine was present in 81.8% of the samples within recommended concentrations. Among samples from water purifiers, 92.9% showed low levels of free residual chlorine (<0.2 mg/L). There was no significant association between chlorine concentrations (either within or outside the recommended range) and the presence of filamentous fungi and yeasts. CONCLUSIONS: This study showed that hospital water can be a reservoir for fungi, some of which are potentially harmful to immunocompromised patients. Free residual chlorine was ineffective in some samples.

Evaluation of disinfection of surfaces at an outpatient unit before and after an intervention program.

BACKGROUND: Cleaning and disinfection processes must be improved so that there is a reduction in environmental contamination of frequent-contact surfaces. The objective of this study was to evaluate cleaning and disinfection of surfaces at a specialized healthcare unit after an intervention program. METHODS: Exploratory, longitudinal, and correlational study carried out in a medium-complexity clinic. Two hundred and forty samples from five surfaces were collected during three phases: diagnosis; implementation of an intervention program; and evaluation of immediate and long-term effects. In total, 720 evaluations were made, performed through three monitoring methods: visual inspection; adenosine triphosphate bioluminescence assay (ATP); and aerobic colony count (ACC). The Wilcoxon, Mann-Whitney, and Fisher's Exact tests were run to analyze data statistically. RESULTS: Cleaning and disinfection of surfaces were not being performed properly in most cases. Failure rates of surfaces reached 37.5 and 100% when the ATP and ACC procedures were used, respectively. However, after an intervention program, an improvement occurred. Success rates increased by 43.96% (ATP) and 12.46% (ACC) in phase I, by 70.6% (ATP) and 82.3% (ACC) immediately after interventions, and by 76.52% (ATP) and 85.76% (ACC) two months after the changes, showing that the program was effective. CONCLUSION: The present study reveals that implementing intervention actions with a cleaning and healthcare team brings benefits to prevent the spread of pathogenic agents through frequently touched hospital surfaces.

Factors associated with self-reported non-completion of the hepatitis B vaccine series in men who have sex with men in Brazil.

BACKGROUND: The objective of the present study was to analyze the factors associated with non-completion of the hepatitis B vaccine series among men who have sex with men and use geosocial dating apps in Brazil. METHODS: This was a cross-sectional, population survey-based, analytical study, conducted exclusively online in all the regions of Brazil, with a sample of 1855 men who have sex with men. The data was collected between November 2016 and February 2017, using the social networking website Facebook. RESULTS: Univariate, bivariate and multivariate analyses showed that 4.7% of the participants reported receiving one dose of the vaccine, 12.5% two doses, 19.4% three doses, and 45.8% did not know. Multivariate analysis showed that level of education (OR = 0.31; CI 95% 0.14-0.72; p = 0.007), identification as bisexual (OR = 0.6; CI 95% 0.38-0.95; p = 0.030), HIV serological status (OR:2.3; CI 95% 1.58-3.34; p = < 0.001) and frequency of access to health services (OR = 2.38; CI 95% 1.53-3.72; p = < 0.001) were associated with not completing the vaccine series. Low completion of the hepatitis B vaccine series was detected in the population studied. CONCLUSION: Completion of the hepatitis B vaccine series was low among men who have sex with men and use geosocial dating apps in Brazil. The factors associated with non-completion were related to social, individual and healthcare (programmatic) vulnerabilities.

CONCLUSION: Among the four instruments applied to assess hospital infection control programs, only two presented results with more than 80.0% of conformity: those related to the epidemiological surveillance and technical-operational structure assessments.

Serophobia related to HIV and AIDS: what is debated in digital social networks in Brazil? / Sorofobia relacionada ao HIV e à Aids: o que se debate nas redes sociais digitais no Brasil?

The aim of this article is to analyze the serophobic content explicit in the publications published in Digital Social Networks in the context of HIV and AIDS in Brazil. This is a qualitative study of the descriptive exploratory type, based on documents. The data obtained were evaluated using the methodology of documentary analysis through Thematic Content Analysis with the aid of NVivo®12 Plus (Windows). A total of 187 codes were generated, subsequently grouped according to the semantics of the words, originating five thematic categories: #LivingWithHIV, #WeNeedtoTalkAboutIt, #WhatISSEROPHOBIA, #SerophobiaIsACrime, and #NoSerophobia. The results showed the main manifestations of HIV and AIDS-related serophobia on social networks. The shared content discussed the difficulties of living with a disease that has social dimensions; the relevance of talking and disseminating content about HIV and AIDS; the elements that make up the stigmatization process and, consequently, structure serophobia in society; the social and civil rights of people living with HIV; measures to combat serophobia in health institutions; and the implications of serophobia in the field of public health.

Impact of the COVID-19 Pandemic Surveillance of Visceral Leishmaniasis in Brazil: An Ecological Study.

The aim of the study was to assess the impact of the COVID-19 pandemic on the notification of new VL cases in Brazil in 2020. It is an ecological and time-series study (2015-2020) with spatial analysis techniques, whose units of analysis were the 5570 Brazilian municipalities. The study population consisted of all new cases of VL recorded between 2015 and 2020. The P-score was calculated to estimate the percentage variation in new VL cases. Global and local univariate Moran's Indices and retrospective space-time scan statistics were used in spatial and space-time analyses, respectively. It was expected that there would be 3627 new cases of VL in Brazil in 2020, but 1932 cases were reported (-46.73%). All Brazilian regions presented a negative percentage variation in the registration of new VL cases, with the Southeast (-54.70%), North (-49.97%), and Northeast (-44.22%) standing out. There was spatial dependence of the disease nationwide in both periods, before and during the first year of the COVID-19 pandemic. There was a significant reduction in the incidence of new VL cases in Brazil during the first year of the COVID-19 pandemic. These findings reinforce the need for better preparedness of the health system, especially in situations of new epidemics.

Migrant Men Living in Brazil during the Pandemic: A Qualitative Study.

This study aims to analyze the repercussions of the ongoing COVID-19 pandemic on the health of male immigrants, refugees, and asylum seekers in Brazil. A qualitative study involving 307 adult men living in Brazil during the COVID-19 pandemic was conducted. Data were collected between August 2021 and March 2022 and interpreted based on the Transcultural Nursing Theory. Cultural care repercussions were identified in various dimensions: technological: changes in daily life and disruptions in routine; religious, philosophical, social, and cultural values: changes stemming from disrupted social bonds, religious practices, and sociocultural isolation; political: experiences of political partisanship, conflicts, government mismanagement, a lack of immigration policies, human rights violations, and xenophobia; educational/economic: challenges arising from economic impoverishment, economic insecurity, unemployment, language difficulties, and challenges in academic and literacy development during the pandemic. The persistence of the COVID-19 pandemic in Brazil had significant repercussions for the health of migrant men, resulting in a transcultural phenomenon that requires sensitive nursing care. Implications for nursing: the uniqueness of cultural care in nursing and health, as most of the repercussions found were mostly negative, contributed to the increase in social and health vulnerabilities.

Occurrence of musculoskeletal disorders, burnout, and psychological suffering in Brazilian nursing workers: A cross-sectional study.

Background: Musculoskeletal disorders (MSDs) pose a pervasive concern among nursing professionals due to the high physical workload. Simultaneously, the complex relationship between MSDs and mental health outcomes in this population remains an area of significant interest and importance. Objective: This study aimed to investigate the occurrence of MSDs and their relationships with burnout and psychological suffering within the nursing workforce. Methods: A cross-sectional study was conducted in 2020 involving 291 nursing professionals in Brazil. Standardized questionnaires were employed to gather information on MSDs, mental health outcomes, and pertinent work-related factors. Robust statistical analyses were conducted to ascertain the prevalence of MSDs, establish associations between MSDs and mental health outcomes, and delineate the influence of work-related factors on these associations. Statistical analysis was performed using the R software. Results: The study revealed a significant prevalence of musculoskeletal injuries (MSIs) among nursing workers, focusing on regions that include the lower back, upper back, neck, and shoulders. Individuals with MSIs in the lower back showed a marked increase in emotional exhaustion (p = 0.02), as did those with MSIs in the upper back (p <0.01) and depersonalization (p = 0.07). On the other hand, nursing professionals who reported MSIs in the neck and shoulders had considerably higher scores in emotional exhaustion (p <0.01 and p = 0.01, respectively) and depersonalization (p = 0.05 and p = 0.05, respectively). However, no significant correlations emerged between MSIs and depression or work-related factors. Conclusions: This study highlights the urgency of implementing proactive measures to prevent and manage MSDs within the nursing profession. Moreover, it emphasizes the critical need to enhance working conditions and provide robust support mechanisms to safeguard the mental health of nursing professionals.Open AccessOpen Access.

Exploring men's health in medium and high complexity care in Brazil: A deductive thematic analysis of social determinants.

Background: Men's health is influenced by a complex interplay of social, economic, and cultural determinants. Understanding how these aspects affect the health of adult cisgender men in medium and high-complexity healthcare settings is essential for improving healthcare services and promoting better health outcomes. Objective: This study aimed to analyze the health status of adult cisgender men in medium and high-complexity healthcare settings based on social determinants and conditioners. Methods: This study employed a qualitative design involving 45 adult cisgender men receiving care in medium/high complexity services in Bahia, Brazil. Semi-structured interviews were conducted from July 2019 to February 2020, and data were interpreted based on Dahlgren and Whitehead's Model of Social Determinants of Health using deductive thematic analysis. Results: Proximal determinants included biological aspects, preventive behaviors, lifestyle/social life, and aging processes. Intermediate factors included work conditions, access/utilization of healthcare services/medications, and psychosocial factors. Macro determinants involved income distribution, power dynamics, resource allocation, health inequalities/iniquities, morbidity, culture, political decisions, environmental factors, and structural elements. Conclusion: The health status of men in medium/high complexity care was profoundly influenced by structural social determinants. These determinants impacted healthcare attention, service organization, cultural influences, the reproduction of hegemonic masculinity patterns, lifestyle, social support, and socioeconomic conditions necessary to realize the right to health. Nursing practices should conduct comprehensive assessments that extend beyond physical health indicators.

BACKGROUND: Contamination of the breathing circuit and medication preparation surface of an anesthesia machine can increase the risk of cross-infection. OBJECTIVE: To evaluate the contamination of the anesthetic medication preparation surface, respiratory circuits, and devices used in general anesthesia with assisted mechanical ventilation. DESIGN AND SETTING: Cross-sectional, quantitative study conducted at the surgical center of a philanthropic hospital, of medium complexity located in the municipality of Três Lagoas, in the eastern region of the State of Mato Grosso do Sul. METHODS: Eighty-two microbiological samples were collected from the breathing circuits. After repeating the samples in different culture media, 328 analyses were performed. RESULTS: A higher occurrence of E. coli, Enterobacter spp., Pseudomonas spp., Staphylococcus aureus, and Streptococcus pneumoniae (P < 0.001) were observed. Variations were observed depending on the culture medium and sample collection site. CONCLUSION: The study findings underscore the inadequate disinfection of the inspiratory and expiratory branches, highlighting the importance of stringent cleaning and disinfection of high-touch surfaces.

Chemsex and its repercussions on the health of men who have sex with men (MSM): a global health perspective.

OBJECTIVES: to discuss the repercussions of chemsex on the health of men who have sex with men (MSM), contextualizing it in a global health scenario and pointing out the implications for nursing care. METHODS: theoretical-reflexive study based on scientific literature and concepts related to global health. RESULTS: we present the epidemiology of the chemsex phenomenon, the main demands of the field, the reasons why it has become a global public health problem, and the implications for nursing practice. FINAL CONSIDERATIONS: chemsex is growing in all age groups of MSM and is globally benefiting from location-based applications to gain magnitude, finding an important potential audience in the migrant population. Nursing structures can help accelerate the proposal and implementation of biomedical and behavioral measures to address chemsex in its entirety, qualifying care and inducing teamwork with interprofessional collaboration.

Validation of the Opening Minds Scale for Health Care Providers (OMS-HC): Factor Structure and Psychometric Properties of the Brazilian Version.

Stigma towards people with mental illness is also present among health professionals. The study validated and estimated the reliability, dimensionality and structure of the Opening Minds Stigma Scale for Health Care Providers (OMS-HC) scale in Brazil. In this methodological study, health professionals (n = 199) from Family Health Units in Brazil were recruited by convenience sampling. The EFA conducted with 16 items resulted in four factors. The Cronbach's Alpha for the OMS scale was 0.74, which is considered to reflect reasonable reliability. The data presented contribute to the use of the scale in studies that investigate the level of stigma among health professionals towards people with mental illness, as well as in the development of anti-stigma interventions in this context.

Spatial modeling of homicide mortality in the Northeast region of Brazil.

OBJECTIVE: To analyze the spatiotemporal distribution of homicide mortality and association with social determinants of health in the Northeast Region of Brazil. METHODS: Ecological study with spatiotemporal modeling of homicide deaths between 2000 and 2019. Temporal trends were analyzed by segmented linear regression. Crude mortality was calculated and adjusted by smoothing the local empirical Bayesian method and analyzed by the Global/Local Moran Index and spatiotemporal scan statistics. The association between social determinants of health and homicide mortality was performed using multiple linear regression and autoregressive spatial models. RESULTS: 353,089 deaths were recorded. Mortality increased from 2000 to 2019, with an annual increase of 4.37 in males and 3.57 in females. High risk spatial and spatiotemporal clusters were identified in the coastal region of the states. The spatial regression model showed an association with socioeconomic inequalities. CONCLUSIONS: High risk areas for homicides associated with socioeconomic inequality, which should be considered as a priority for designing and investing in public health policies were investigated.

Impact of an educational intervention on standard precautions during the COVID-19 pandemic.

OBJECTIVE: To evaluate the impact of an educational intervention on the knowledge of nursing professionals regarding standard precautions. METHODS: This is an almost experimental study conducted with 100 nursing professionals. Data collection was performed using a sociodemographic characterization instrument and the Standard Precautions Knowledge Questionnaire. The educational intervention was based on five moments, where the approach to questions with less than 70% accuracy was intensified. RESULTS: There was a significant difference between the scores of healthcare professionals before (16.20 ± 1.51) and after (16.90 ± 1.31) the educational intervention (W=3.336; p < 0.05). Regarding knowledge about hand hygiene after glove use, an increase in knowledge from 83% to 93% was obtained. CONCLUSIONS: A positive effect on the professionals' knowledge was recorded, demonstrating advances regarding the strengthening of already acquired knowledge and the understanding of new knowledge.

Misinformation about COVID-19 among middle-aged and older migrants residing in Brazil and Portugal.

OBJECTIVE: The aim of this study was to assess the prevalence of COVID-19 misinformation among migrants aged 50 or older residing in Brazil and Portugal. METHOD: This was a cross-sectional analytical study conducted among migrants from Portuguese-speaking countries living in Brazil and Portugal, who were 50 years of age or older. The prevalence ratios (PR) were estimated using the Poisson regression model. RESULTS: Out of the 304 participants included in the study, 188 (61.8%) agreed with at least one piece of misinformation. Factors such as having a religious affiliation (aPR: 1.24), higher educational attainment (aPR: 1.17), knowing someone who died from COVID-19 (aPR: 1.78), and having no intention to get vaccinated (aPR: 1.36) were associated with a higher likelihood of agreeing with COVID-19 misinformation. CONCLUSION: The findings suggest that access to misinformation was influenced by social, economic, and religious factors among elderly migrants with low digital literacy, thus contributing to the dissemination of false content within this population.

Agreement with COVID-19 disinformation among Portuguese-speaking older adults: an international study.

OBJECTIVES: to assess agreement with COVID-19 disinformation among Portuguese-speaking individuals aged 50 years or older. METHODS: a descriptive and analytical study involving 1,214 older adults born in Portuguese-speaking countries. Data collection occurred through online information mining to recognize COVID-19 and disinformation content, and the application of a structured questionnaire. RESULTS: agreement with disinformation content was 65.2%. Residing outside Brazil is a protective factor for agreement with disinformation content, and those who believe in the truthfulness of the information sources they receive were 31% more likely to agree with disinformation content. CONCLUSIONS: there is a high prevalence of disinformation among the older population in two Portuguese-speaking countries, which should raise the attention of healthcare professionals and guide coping strategies.
