Gallstones are associated with carotid atherosclerosis

Background/Aims: Gallstone disease (GD) and cardiovascular disease (CD) are common diseases worldwide with considerable economical impact and they are strongly associated. Carotid atherosclerosis is an excellent marker of risk for CD like stroke and myocardial infarction. The aim of this study was to assess the association between gallstones and carotid atherosclerosis. Methods: A cross‐sectional study was conducted. We evaluated subjects with ultrasonographical evidence of GD and asymptomatic subjects without such evidence. Anthropometric, clinical and biochemical variables were collected. The Metabolic syndrome was evaluated using adult treatment panel III criteria. Carotid artery intima–media thickness (CIMT) was determined by a standard ultrasound protocol. Insulin‐like growth factor‐1 (IGF‐1) serum levels were measured in all subjects. Results: We studied 191 subjects: 62 subjects with GD (53.2% males) and 129 asymptomatic subjects without GD (65.9% males). Subjects with GD exhibited a higher body mass index, body fat percent, insulin serum levels and CIMT (P<0.05 for all). The prevalence of GD was higher in subjects with a CIMT>0.75 independently of other factors [odds ratio (OR) 2.12, 95% confidence interval (CI) 1.04–4.34; P=0.039], and for every 0.1 mm increase in CIMT the independent probability to be a case of GD increased by a factor of 1.25 (95% CI 1.02–1.53; P=0.027). IGF‐1 levels did not differ among groups. Conclusions: Subjects with GD exhibit greater carotid atherosclerosis, and therefore have a higher risk for stroke and myocardial infarction.     

Aumento de Óbitos Domiciliares devido a Parada Cardiorrespiratória em Tempos de Pandemia de COVID-19

BackgroundCardiovascular diseases constitute an important group of causes of death in the country. Ischemic heart diseases that are the main causes of cardiopulmonary arrest, leading to an impact on the mortality of the cardiovascular diseases in the health system.ObjectiveAssess the number of home deaths by cardiopulmonary arrest notified by the Mobile Emergency Medical Service (SAMU) in March 2018, 2019 and 2020.MethodsObservational study carried out from the analysis of cardiopulmonary arrest mortality data of citizens assisted by SAMU in Belo Horizonte, Minas Gerais, Brazil. Social and clinical characteristics and occurrence information of the patients were analyzed. The mortality rate due to cardiopulmonary arrest in relation to the total number of attendances was assessed. A significance level of 95% was considered.ResultsThere was increase of home deaths due to cardiopulmonary arrest in March 2020 compared to March 2018 (p<0.001) and March 2019 (p=0.050). Of the deaths reported in 2020, 63.8% of the patients were aged 60 years or older, 63.7% of the occurrences were performed in the afternoon and approximately 87% of the cardiopulmonary arrest notified had associated clinical comorbidities, with systemic arterial hypertension and heart failure represented by 22.87% and 13.03% of the reported cases, respectively. The majority of the evaluated sample of this study did not have any medical care follow-up (88.7%).ConclusionConsidering the increase in the number of the deaths, we suggest reflections and readjustments regarding the monitoring of chronic non-transmissible diseases during a pandemic, as well as improvements in death surveillance.

Love,Trust, and HIV Risk Among Female Sex Workers and Their Intimate Male Partners

Objectives. We examined correlates of love and trust among female sex workers and their noncommercial male partners along the Mexico–US border.Methods. From 2011 to 2012, 322 partners in Tijuana and Ciudad Juárez, Mexico, completed assessments of love and trust. Cross-sectional dyadic regression analyses identified associations of relationship characteristics and HIV risk behaviors with love and trust.Results. Within 161 couples, love and trust scores were moderately high (median 70/95 and 29/40 points, respectively) and correlated with relationship satisfaction. In regression analyses of HIV risk factors, men and women who used methamphetamine reported lower love scores, whereas women who used heroin reported slightly higher love. In an alternate model, men with concurrent sexual partners had lower love scores. For both partners, relationship conflict was associated with lower trust.Conclusions. Love and trust are associated with relationship quality, sexual risk, and drug use patterns that shape intimate partners’ HIV risk. HIV interventions should consider the emotional quality of sex workers’ intimate relationships.While public health interventions continue to be grounded in tenets of risk and disease, there is growing recognition of the importance of emotions such as love and trust in shaping the health behaviors of diverse populations. Unprotected sex allows for transmission of HIV and other sexually transmitted infections (STIs) but often carries emotional meanings of trust and commitment that impede condom negotiation even among individuals with high knowledge and self-efficacy.1–4 Research has consistently found female sex workers’ condom use to be less frequent with their noncommercial male partners than with clients, which has been linked to intimacy, love, and trust.5–7 Similarly, drug-using couples may share syringes and engage in additional known HIV risk behaviors to convey support and emotional closeness.8,9 Although much of this research is qualitative, some quantitative work has confirmed associations between perceptions of intimacy and condom use among sex workers and clients10 and men who have sex with men.11Quantitative researchers have attempted to operationalize emotions into theoretical constructs for empirical research.12 Sternberg’s “triangular” theory posits that love comprises 3 components: intimacy (feelings of emotional closeness between partners), passion (physical attraction and sexual consummation), and commitment (decisions that partners make about maintaining relationships).13,14 Taken together, these components combine to generate different kinds of love.13,15,16Another important aspect of intimate relationships, trust is conceptualized as a belief in the integrity of a partner. Trust may be based on individuals’ assessments of their partners’ benevolence and honesty17 and subjective feelings of security within relationships.18,19 To measure trust quantitatively, Larzelere and Huston developed a dyadic trust scale that correlated with love and relationship quality.17A rich body of ethnographic scholarship has highlighted the importance of companionate relationships and love in diverse global contexts,20–22 but quantification of emotional constructs are largely absent from settings outside the Western middle-class experience. Most quantitative studies of love and trust have focused on privileged populations who do not experience the burden of disease that disproportionately affects socially marginalized couples. Existing studies among US populations have also suggested that women and men value components of these emotions differently,23–25 yet the implications of these potential gender differences for HIV prevention among vulnerable couples remains underexplored.Our study of love and trust among sex workers and their noncommercial partners is situated in 2 Mexican border cities: Tijuana, Baja California, south of San Diego, California (population 1.6 million), and Ciudad Juárez, Chihuahua, adjacent to El Paso, Texas (population 1.3 million). Both cities have areas where sex work and drug use are concentrated,26 lending to the conceptualization of the border as an HIV risk environment27 characterized by poverty, unemployment, violence, and availability of illicit drugs.28 Research has documented substantial overlap in risky sexual and injection drug use behaviors among marginalized female sex workers29 who often turn to sex work as a last option for supporting themselves and their dependents.30Drawing on Connell’s conceptualization of gender as a relational process influenced by structural and sociocultural factors,31 our previous qualitative and ethnographic inquiry into sex workers’ intimate partnerships in these cities proposed that emotions are shaped by the HIV risk environment of the border. Structural conditions bring partners together into relationships that provide critical material and emotional support. In light of limited economic opportunities, couples form tacit agreements regarding women’s engagement in sex work. In the process, women emerge as primary wage earners, alienating men from traditional gender roles as providers and shifting gender dynamics. To cope, partners mostly avoid communicating about sex work or disclosing HIV risk to protect the emotional integrity of the relationship.32We also found that these couples’ relationships range in emotional intensity from friendship and care to transformative experiences of love. Regardless, most couples demarcate their primary relationships from sex work by engaging in unprotected sex. Among couples who inject drugs, sharing syringes together (but not with others) often reinforces trust and care.33 Concerns of mistrust and infidelity also reduced couples’ interest in alternative HIV-prevention technologies such as pre-exposure prophylaxis.34In light of the central role of emotions in our qualitative research with these couples, we attempted to quantify constructs of love and trust and identify associated relationship traits and HIV risk behaviors in our larger cohort. We hypothesized that markers of relationship quality (e.g., higher satisfaction, lower conflict) and unprotected sex within primary relationships would be associated with higher love and trust, whereas extradyadic HIV risk behaviors (e.g., concurrent sexual partners, syringe sharing with others) would be associated with lower love and trust.

Occurrence, productivity and spatial distribution of key-premises in two dengue-endemic areas of Rio de Janeiro and their role in adult Aedes aegypti spatial infestation pattern

Objectives To evaluate: (1) the occurrence, maintenance, productivity, spatial distribution and premise condition index score of Adese aegypti‐infested houses and key‐premises in a suburban district (Tubiacanga) and a slum (Favela do Amorim) of Rio de Janeiro and (2) the role of these factors in adult Ae. aegypti female spatial distribution. Methods and Results A total of 2456 premises were inspected for immature and 1100 for adult collection. Key‐premises corresponded to 16.08% and 17.86% of infested houses in Tubiacanga, and 13.5% and 11.1% in Favela do Amorim, during the dry and wet seasons, respectively. Key‐premises held significantly more immature Ae. aegypti, pupae and larvae than infested houses in Favela do Amorim and Tubiacanga during the dry and wet seasons. In Favela do Amorim, key‐premises had a significantly higher PCI score than infested but non‐key houses. Conclusion The spatial distribution of key‐premises and adult Ae. aegypti females was often congruent, indicating that key‐premises influence the infestation pattern observed in the study areas.
