Morphometry and skeletopy of kidneys and renal vessels in marmoset (Callithrix spp.).

BACKGROUND: Marmosets, Callithrix spp, are small New World monkeys that have gained importance as an experimental animal model for human. Despite its use, information on its renal morphometry, vascularization, and location are limited. Therefore, this study will supply basic anatomy for applied studies and for comparative anatomy. METHODS: Fifty cadavers of Callithrix spp were collected on highways from the Atlantic Forest biome, identified and injected with a 10% formaldehyde solution. Later, the specimens were dissected and the measurements and topography of the kidneys and renal vessels were recorded. Both left and right kidneys were significantly larger in females. RESULTS: In the specimens studied, the average body length was 20.00 ± 2.46 cm in males and 20.50 ± 1.98 cm in females (p = .43). The kidneys of the Callithrix spp. were symmetrical in shape and resembled a "bean." They were also pale brown with a smooth surface. In males, the most frequent location of the right kidney was at the L1-L2 level (92%), while the location of the left kidney was between L2 and L3 (76%). In females, the most frequent location of the right kidney was at the L1-L2 level (56%), while the location of the left kidney was between L2 and L3 (32%) (Table 1). However, in seven (28%) males and nine (36%) females, the kidneys were at the same level. CONCLUSIONS: In both sexes, there was a positive and significant linear correlation between body length and kidney length. Regardless of the variable location of the kidneys in both sides and in either sexe, the right kidney was always located more cranially than the left, similar to observations in other non-human primates.

Using Respondent-Driven Sampling (RDS) to Identify the Healthcare Needs among Women of Reproductive Age Who Migrated from Venezuela to Brazil, 2018-2021.

In 2021, an RDS survey was conducted among Venezuelan migrant women of reproductive age who migrated to two Brazilian cities (Manaus and Boa Vista) from 2018 to 2021. To start the RDS recruitment, we chose seeds non-randomly in both cities. The study variables were age, educational level, self-rated health, pregnancy, migratory status and use of health services. We estimated the prevalence, confidence intervals and homophily effects by variable category. We used a multivariate logistic regression model to identify the main factors associated with healthcare use. A total of 761 women were recruited in Manaus and 1268 in Boa Vista. Manaus showed more irregular migrants than Boa Vista. The main reasons for using health services were as follows: illness, disease prevention and prenatal care. The logistic regression model showed the use of health services was associated with educational level and healthcare needs but not with migratory status. The social inclusion of Venezuelan migrants is extremely relevant, although many challenges must be overcome. The strategy of the Brazilian Federal Government for providing humanitarian assistance to Venezuelan migrants should be expanded to include and facilitate their integration into labor markets, access to healthcare and education, benefiting both migrants and the Brazilian people by reducing social inequality.

Prevalence and factors associated with the perception of perineal laceration: a cross-sectional study with data from the Nascer no Brasil Survey, 2011 and 2012.

OBJECTIVE: To describe the prevalence of perineal laceration, based on the self-reported perception of postpartum women, and to analyze factors associated with its occurrence in Brazil. METHODS: This was a cross-sectional study conducted with 23,894 postpartum women, excluding twin pregnancies, cesarean sections, and births with episiotomies, between 2011 and 2012. Prevalence ratios (PR) and 95% confidence intervals (95%CI) of association between the event and maternal, fetus/newborn, obstetric and clinical management characteristics were estimated in hierarchical Poisson regression models. RESULTS: Out of 4,606 postpartum women, 49.5% (95%CI 46.1;42.9) self-reported perineal laceration. Being an adolescent (PR = 1.12; 95%CI 1.02;1.25), primipara (PR = 1.47; 95%CI 1.33;1.63), having had excessive gestational weight gain (PR = 1.17; 95%CI 1.07;1.29) and having undergone the Kristeller maneuver (PR = 1.18; 95%CI 1.08;1.29) increased the proportion of the outcome. CONCLUSION: The results found call for prenatal care and adjustments to childbirth care so as to be in accordance with current recommendations. MAIN RESULTS: Prevalence of self-reported perineal laceration was 49.5%. Being in the adolescent age group, primiparity, excessive gestational weight and the Kristeller maneuver were risk factors associated with the event. IMPLICATIONS FOR SERVICES: Studying self-reported prevalence of perineal laceration supports new care practices, highlights the prevention of risk factors considered modifiable and confirms the need to follow current guidelines. PERSPECTIVES: New national studies are needed comparing prevalence of self-reported perineal laceration with that recorded in medical records in order to support care practices and public obstetric policies.

Prevalence of trachoma in indigenous and non-indigenous areas, Northeastern Brazil, 2019-2021.

Objective: To estimate the prevalence of trachoma in indigenous and non-indigenous populations in selected areas of the state of Maranhão, in northeastern Brazil. Methods: This was a population-based survey with probabilistic sampling. For the diagnosis of trachoma, external ocular examination was performed using head magnifying loupes, at 2.5X magnification. The prevalence of trachomatous inflammation - follicular (TF) in children aged 1-9 years and the prevalence of trachomatous trichiasis (TT) in the population aged ≥15 years were estimated. Relative frequencies of sociodemographic and environmental characteristics were obtained. Results: The study included 7 971 individuals, 3 429 from non-indigenous populations and 4 542 from indigenous populations. The prevalence of TF in non-indigenous and indigenous populations was 0.1% and 2.9%, respectively, and the prevalence of TT among indigenous populations was 0.1%. Conclusions: The prevalence of TF and TT in the two evaluation units in the state of Maranhão were within the limits recommended for the elimination of trachoma as a public health problem. However, the prevalence of TF was higher in the indigenous evaluation unit, indicating a greater vulnerability of this population to the disease. The prevalence of TF of below 5.0% implies a reduction in transmission, which may have resulted from improved socioeconomic conditions and/or the implementation of the World Health Organization SAFE strategy.

Brain volumetry from CT-scan endocasts of three neotropical carnivores.

Studies on brain anatomy can clarify specific evolutionary and behavioural aspects of wild animals. The rich diversity in a broad range of habitats makes carnivorans especially eligible for studying the relations between the brain form and behaviour, cognitive, sensorial and motor traits. This study compared the brain's contour and total and segmented brain volumetry in three species of neotropical carnivorans. CT images of 17 skulls of three species were acquired: Conepatus chinga (n = 6), Galictis cuja (n = 6) and Lontra longicaudis (n = 5). Three-dimensional endocasts allowed for estimating the brain's total and segmented volumes (olfactory bulb, rostral cerebrum, caudal cerebrum and cerebellum/brain stem). The average volume percentage of the segments was compared interspecifically and intraspecifically between the sexes. The otter has a notably more complex gyrification, typical for semiaquatic carnivorans. Proportionally, the olfactory bulb was significantly larger in hog-nosed skunks, possibly due to a better sense of smell for capturing insects. The proportional volumes of the rostral cerebrum, caudal cerebrum and cerebellum/brain stem segments did not differ between these species. Social behaviour traits and tactile, motor and balance skills were probably not sufficiently distinct to reflect differences in the brain segments analysed in these three species.

RESUMEN Objetivo. Estimar la prevalencia del tracoma en poblaciones indígenas y no indígenas en determinadas zonas del estado de Maranhão, en el nordeste de Brasil. Métodos. Se trató de una encuesta de ámbito poblacional con muestreo probabilístico. Para el diagnóstico del tracoma, se realizó un examen ocular externo con una lupa frontal de 2,5X aumentos. Se estimó la prevalencia de la inflamación tracomatosa folicular (TF) en la población infantil de 1 a 9 años y la prevalencia de la triquiasis tracomatosa (TT) en la población de 15 años o más. Se obtuvieron las frecuencias relativas de las características sociodemográficas y ambientales. Resultados. En el estudio participaron 7 971 personas, 3 429 de poblaciones no indígenas y 4 542 de poblaciones indígenas. La prevalencia de la TF en las poblaciones no indígenas e indígenas fue de 0,1% y 2,9%, respectivamente, en tanto que la de la TT en las poblaciones indígenas fue de 0,1%. Conclusiones. La prevalencia de la TF y la TT en las dos unidades de evaluación del estado de Maranhão estuvo dentro de los límites recomendados para la eliminación del tracoma como problema de salud pública. Sin embargo, la prevalencia de la TF fue mayor en la unidad de evaluación indígena, lo que indica una mayor vulnerabilidad de esta población a la enfermedad. La prevalencia de la TF inferior al 5,0% implica una reducción de la transmisión, que puede haber sido consecuencia tanto de la mejora de las condiciones socioeconómicas como de la aplicación de la estrategia SAFE de la Organización Mundial de la Salud.

Coronary anatomy in neotropical carnivores: A comparative analysis.

This study aims to investigate the anatomy of coronary arteries and their primary branches in neotropical carnivores, given the functional significance of coronary circulation and the limited existing descriptions in this order. For this purpose, coronary arteries were dissected, and their branches were counted in 74 hearts from 20 species belonging to five families: Canidae, Mustelidae, Procyonidae, Mephitidae, and Felidae. In all specimens of the suborder Caniformia, the subsinuosal interventricular branch originated at the end of the circumflex branch of the left coronary artery (LCA). In contrast, in all hearts of Felidae specimens, the subsinuosal branch was derived from the right coronary artery. Among the 50 neotropical specimens of the suborder Caniformia, 13.1 ± 5.2 ventricular branches originated from the LCA and only 4.6 ± 1.4 from the right (p < 0.0001), characterizing a consistent left dominance. However, in the 24 specimens of the Felidae family, 10.5 ± 4.0 ventricular branches were found originating from the LCA and 10.4 ± 3.4 from the right, with no difference between the means (p = 0.82), defining a balanced pattern. It is suggested that the type of coronary circulation may correlate with the phylogeny of carnivorans.

Papanicolaou test in Brazil: analysis of the National Health Survey of 2013 and 2019.

OBJECTIVES: To compare the coverage of cervical cancer screening in Brazil in 2013 and 2019, investigating the factors associated with having the test performed and the reasons given for not doing it. Additionally, a comparison is made concerning the time taken to receive the test result in SUS (Sistema Único de Saúde) and in the private health services. METHODS: Using data from the National Health Survey (Pesquisa Nacional de Saúde - PNS), prevalence rates and corresponding confidence intervals were calculated to determine the frequency of recent cervical cancer screenings among women aged between 25 and 64 years old in Brazil, for both 2013 and 2019. Poisson regression models were employed to compare the prevalence of the outcome according to sociodemographic characteristics. The reasons for not having the test and the time between performing and receiving the result were also analyzed. RESULTS: The findings revealed an increase in the coverage of preventive cervical cancer exams in Brazil from 78.7% in 2013 to 81.3% in 2019. Additionally, there was a decline in the proportion of women who had never undergone the exam, from 9.7% to 6.1%. Prevalence of test uptake was higher among white women, those with higher levels of education and income, and those residing in the South and Southeast regions of the country. The most commonly cited reasons for not taking the test were the impression it was unnecessary (45% in both 2013 and 2019) and never having been asked to undergo the test (20.6% in 2013 and 14.8% in 2019). CONCLUSIONS: Despite the high coverage of screening achieved in the country, there is great inequality in access to the test, and a non-negligible number of women are at greater risk of dying from a preventable disease. Efforts must be made to structure an organized screening program that identifies and captures the most vulnerable women.

Sexual behavior and self-declaration of sexual orientation among people 18-64 years in Brazil: results from the Knowledge, Attitudes, and Practices survey, 2013 and the National Health Survey, 2019.

BACKGROUND: Population surveys involving the monitoring of high-risk sexual behavior have been recognized as important public health tools to control the HIV epidemic and other sexually transmitted infections (STIs). METHODS: Using data from the Knowledge, Attitudes, and Practices survey (PCAP-2013) and from the National Health Survey (PNS-2019), indicators of sexual behavior were compared according to sociodemographic characteristics among individuals aged 18-64 years, including size (%) estimates of men who have sex with men (MSM) and women who have sex with women (WSW). Specifically, the PNS-2019 prevalence estimates of homosexual, bisexual, heterosexual males and females were compared with those from the PCAP-2013. To compare PCAP and PNS proportional distributions, the Pearson's chi-square test, adjusted by the Rao-Scott's correction, was applied. RESULTS: Size (%) estimates of MSM and WSW obtained by direct questions from the PCAP-2013, showed higher homosexuality prevalence estimates than those resulting from the PNS-2019 self-declared sexual orientation. Significant differences were found between the MSM proportions according to the PCAP-2013 (3.7%; 95% CI 3.1-4.4%) and to the PNS-2019 (2.2%; 95% CI 1.9-2.5), and between the WSW proportions (4.6%; 95% CI 4.0-5.4%) and (2.1%; 95% CI 1.8-2.4), respectively. Results from both surveys showed MSM and WSW prevalence estimates increase with educational level, decrease with age, and is larger among people who do not live with partner, live in urban areas and in state capitals. Regarding condom use at last sexual intercourse, no differences between the PCAP-2013 and the PNS-2019 estimates were found at the national level, but significant improvements were found for MSM, people aged 18-24 and 25-34 years, and individuals not living with a partner. CONCLUSIONS: The underestimation of MSM and WSW prevalence by self-declared sexual orientation suggests that sexual minorities face many difficulties related to disclosing their sexuality and reinforces the importance of developing public health interventions for changing population attitudes and promoting sexual orientation disclosure. Moreover, the low use of condoms in both surveys (PCAP-2013 and PNS-2019) carried out 6 years apart highlights the need of public policies to expand prevention strategies for HIV infection and other STIs.

Cohort study of hospitalized patients with COVID-19 at Brazilian tertiary-care hospital: Occurrence of adverse events and mortality.

INTRODUCTION: Patients hospitalized with COVID-19 are often submitted to invasive procedures and they are at risk for hospital-associated adverse events. OBJECTIVES: To evaluate the epidemiological and clinical aspects of patients hospitalized with COVID-19; the occurrence of adverse events and the risk factors for mortality. METHOD: Cohort study that included adult patients hospitalized with a diagnosis of SARSCoV-2 infection, at the tertiary University Hospital of UNICAMP from March 2020 to March 2021. Patients were identified through the hospital epidemiological surveillance system and followed until discharge or death. Descriptive, comparative, and logistic regression analysis was performed. RESULTS: 650 adult patients were included. The main adverse events identified were nosocomial infections (31.5%), renal failure (33.8%), thromboembolic and vascular events (12.6%). Mortality was higher among those with bloodstream infections (30.2% vs. 8.6%; p < 0.0001), ventilator-associated pneumonia (VAP, 52.5% vs. 12.3%; p < 0.0001), catheter associated urinary infection (27.3% vs. 7.2%; p < 0.0001); thromboembolic and vascular events (23.0% vs. 9.9%; p < 0.0001) and renal failure (81.3% vs. 20.9%; p < 0.0001). Klebsiella pneumoniae (15.6%), Pseudomonas aeruginosa (14.4%), Enterococcus faecalis (8.6%) were the most isolated bacteria. Logistic regression analysis identified age, (RR = 1.03; 95% CI 1.02 to 1.05); ICU admission (RR = 3.06; 95% CI 1.59 to 5.87), vasoactive drug use (RR = 3.1; 95% CI 1.79 to 4.82); renal failure (RR = 7.76; 95% CI 4.54 to 13.26); and VAP (RR = 2.2; 95% CI 1.23 to 3.96), independently associated with mortality. CONCLUSION: adverse events have an important impact on the evolution of patients with COVID-19, reinforcing the need for optimized prevention and control measures as an essential part of care for these patients.

[Self-reported morbidities and lifestyles of agricultural and non-agricultural workers in Brazil: a comparative analysis between 2013 and 2019]. / Morbidades autorreferidas e estilos de vida em trabalhadores agrícolas e não agrícolas no Brasil: uma análise comparativa entre 2013 e 2019.

Differences in the profiles of illness and lifestyles among agricultural and non-agricultural workers were investigated using data from the National Health Survey (Brazilian acronym PNS) of 2013 and 2019. The prevalence and 95% CIs were calculated for the following variables: self-reported morbidities, poor self-rated health, limitations of usual activities, number of NCD, major or minor depression and lifestyles. The Poisson model was used to calculate crude and adjusted prevalence ratios, by gender and age. The sample weights and the conglomerate effect in 2013 and 2019 were considered in the analyses. A total of 33,215 non-agricultural workers and 3,797 agricultural workers were evaluated in 2013, whereas 47,849 non-agricultural workers and 4,751 agricultural workers were assessed in 2019. Agricultural workers are more susceptible to poor self-rated health, chronic back problems, excessive physical activity at work, smoking and lower consumption of vegetables and fruit. On the other hand, non-agricultural workers revealed a higher prevalence of asthma/bronchitis, depression and diabetes mellitus and greater consumption of candies and soft drinks. Differentiated NCD prevention and treatment actions for both groups of workers need to be prioritized.

Investigaram-se diferenças no padrão de adoecimento e estilos de vida entre trabalhadores agrícolas e não agrícolas em 2013 e 2019, com os dados da Pesquisa Nacional de Saúde (PNS). Calcularam-se as prevalências e seus IC de 95% para morbidades autorreferidas, autoavaliação de saúde (AAS) não boa, limitação das atividades habituais por DCNT, número de DCNT, depressão maior ou menor e estilos de vida. Utilizou-se o modelo de Poisson para cálculo das razões de prevalências brutas e ajustadas por sexo e idade. Consideraram-se as ponderações amostrais e o efeito do conglomerado em 2013 e 2019. Avaliaram-se 33.215 trabalhadores não agrícolas e 3.796 agrícolas em 2013. Em 2019, foram 47.849 trabalhadores não agrícolas e 4.751 agrícolas. Os trabalhadores agrícolas estão mais propensos a AAS não boa, problemas crônicos na coluna, excesso de atividade física no trabalho, tabagismo e menor consumo de frutas, legumes e verduras (FLV). Enquanto os trabalhadores não agrícolas apresentaram maiores prevalências de asma/bronquite, depressão, diabetes, e consumo de doces e refrigerantes. Ações diferenciadas de prevenção e manejo de DCNT para os dois grupos de trabalhadores devem ser priorizadas.

Factors associated with worsening in the self-rated health status of Brazilian women who lived with dependent elderly people during the first wave of COVID-19. / Fatores associados à piora da autoavaliação da saúde das brasileiras que residiam com idosos dependentes durante a primeira onda da COVID-19.

The objective is to analyze the factors associated with the worsening of the self-rated health (SRH) of Brazilian women who live with elderly people with functional dependence (EFD) during the first wave of COVID-19. ConVid - Behavior Research was used as a data source. For the analysis, the group of women who lived with EFD was compared with those who lived with the elderly without any dependence. Hierarchical prevalence ratio (PR) models were estimated to test the associations between sociodemographic characteristics, changes in income, routine activities and health in the pandemic, with the outcome of worsening SRH. This worsening was more frequent in the group of women living with EFD. After adjusting for hierarchical factors, being black (PR=0.76; 95%CI 0.60-0.96) and having a per capita income lower than minimum wage (PR=0.78; 95%CI 0.64- 0.96) were shown to be protective factors for SRH worsening among EFD co-residents. Indisposition, emergence/worsening of back problems, affected sleep, poor SRH, feeling loneliness and difficulty in carrying out routine activities during the pandemic were positively associated factors. The study demonstrates that living with EFD was associated with a worsening in the health status of Brazilian women during the pandemic, especially among those of higher social status.

O objetivo do artigo é analisar os fatores associados à piora da autoavaliação da saúde (AAS) de brasileiras que residiam com idosos com dependência funcional (IDF) durante a primeira onda da pandemia de COVID-19. Utilizou-se a ConVid - Pesquisa de Comportamentos como fonte de dados. Para a análise comparou-se o grupo de mulheres que moravam com IDF com aquelas que moravam com idosos sem dependência. Estimou-se modelos hierárquicos de razão de prevalência (RP) para testar as associações entre as características sociodemográficas, mudanças na renda, atividades de rotina e saúde na pandemia, tendo como desfecho a piora da AAS. A piora da AAS foi mais frequente no grupo de mulheres que moravam com IDF. Após o ajuste dos fatores hierárquicos, ser negra (RP=0,76; IC95% 0,60-0,96) e ter renda per capita menor que um salário-mínimo (RP=0,78; IC95% 0,64-0,96) foram fatores inversamente associados à piora da AAS entre corresidentes de IDF. O estado de ânimo ruim, o surgimento/piora de problema de coluna, o sono afetado, a AAS ruim, o sentimento de solidão e a dificuldade na realização de atividades rotineiras durante a pandemia foram fatores positivamente associados. O estudo demonstra que morar com IDF esteve associado à piora da saúde das brasileiras na pandemia, especialmente entre aquelas em posição de maior status social.

The Poisson model was used to calculate crude and adjusted prevalence ratios, by gender and age. The sample weights and the conglomerate effect in 2013 and 2019 were considered in the analyses. A total of 33,215 non-agricultural workers and 3,797 agricultural workers were evaluated in 2013, whereas 47,849 non-agricultural workers and 4,751 agricultural workers were assessed in 2019. Agricultural workers are more susceptible to poor self-rated health, chronic back problems, excessive physical activity at work, smoking and lower consumption of vegetables and fruit. On the other hand, non-agricultural workers revealed a higher prevalence of asthma/bronchitis, depression and diabetes mellitus and greater consumption of candies and soft drinks. Differentiated NCD prevention and treatment actions for both groups of workers need to be prioritized.

Fatores associados à piora da autoavaliação da saúde das brasileiras que residiam com idosos dependentes durante a primeira onda da COVID-19 / Factors associated with worsening in the self-rated health status of Brazilian women who lived with dependent elderly people during the first wave of COVID-19

Resumo O objetivo do artigo é analisar os fatores associados à piora da autoavaliação da saúde (AAS) de brasileiras que residiam com idosos com dependência funcional (IDF) durante a primeira onda da pandemia de COVID-19. Utilizou-se a ConVid - Pesquisa de Comportamentos como fonte de dados. Para a análise comparou-se o grupo de mulheres que moravam com IDF com aquelas que moravam com idosos sem dependência. Estimou-se modelos hierárquicos de razão de prevalência (RP) para testar as associações entre as características sociodemográficas, mudanças na renda, atividades de rotina e saúde na pandemia, tendo como desfecho a piora da AAS. A piora da AAS foi mais frequente no grupo de mulheres que moravam com IDF. Após o ajuste dos fatores hierárquicos, ser negra (RP=0,76; IC95% 0,60-0,96) e ter renda per capita menor que um salário-mínimo (RP=0,78; IC95% 0,64-0,96) foram fatores inversamente associados à piora da AAS entre corresidentes de IDF. O estado de ânimo ruim, o surgimento/piora de problema de coluna, o sono afetado, a AAS ruim, o sentimento de solidão e a dificuldade na realização de atividades rotineiras durante a pandemia foram fatores positivamente associados. O estudo demonstra que morar com IDF esteve associado à piora da saúde das brasileiras na pandemia, especialmente entre aquelas em posição de maior status social.

Abstract The objective is to analyze the factors associated with the worsening of the self-rated health (SRH) of Brazilian women who live with elderly people with functional dependence (EFD) during the first wave of COVID-19. ConVid - Behavior Research was used as a data source. For the analysis, the group of women who lived with EFD was compared with those who lived with the elderly without any dependence. Hierarchical prevalence ratio (PR) models were estimated to test the associations between sociodemographic characteristics, changes in income, routine activities and health in the pandemic, with the outcome of worsening SRH. This worsening was more frequent in the group of women living with EFD. After adjusting for hierarchical factors, being black (PR=0.76; 95%CI 0.60-0.96) and having a per capita income lower than minimum wage (PR=0.78; 95%CI 0.64- 0.96) were shown to be protective factors for SRH worsening among EFD co-residents. Indisposition, emergence/worsening of back problems, affected sleep, poor SRH, feeling loneliness and difficulty in carrying out routine activities during the pandemic were positively associated factors. The study demonstrates that living with EFD was associated with a worsening in the health status of Brazilian women during the pandemic, especially among those of higher social status.

Linear CT-scan measurements of cerebral ventricles in senile Poodle dogs.

Breed traits seem to influence the dimensions of the cerebral ventricles in dogs. The ratios between the ventricles and the brain are crucial diagnostic criteria for suspected canine cognitive dysfunction (CCD). This study aimed to establish linear computed tomography (CT)-scan measurements of the cerebral ventricles in 55 Poodle dogs aged >7 years. To this end, cross-sectional CT images were evaluated. The measurements in the whole sample were: height of the right ventricle, 6.0 ± 1.6 mm; height of the left ventricle, 5.8 ± 1.6 mm; width of the right ventricle, 6.9 ± 1.4 mm; width of the left ventricle, 7.0 ± 1.3 mm; height of the third ventricle, 3.4 ± 0.8 mm; height of the right cerebral hemisphere, 39.5 ± 2.0 mm; and height of the left cerebral hemisphere, 40.2 ± 2.6 mm. The average ventricular measurements were higher in dogs older than 11 years (p < 0.05). However, the average ratio of the ventricle height to the height of the brain did not reveal differences between age groups, sex, or antimeres. In addition, none of the images showed fused lateral ventricles. Thus, these data can assist in interpreting ventricle size in senile Poodle dogs (aged >7 years).

Características raciais parecem influenciar as dimensões dos ventrículos cerebrais em cães. As proporções entre os ventrículos e o cérebro são cruciais para os casos suspeitos de disfunção cognitiva canina (DCC). Este estudo objetivou estabelecer medidas lineares dos ventrículos cerebrais de 55 cães da raça Poodle com idade acima de sete anos. Para tal, foram avaliadas imagens de cortes transversais obtidas por tomografia computadorizada. As medidas na amostragem total foram: altura do ventrículo direito 6,0 ± 1,6 mm, altura do ventrículo esquerdo 5,8 ± 1,6 mm, largura do ventrículo direito 6,9 ± 1,4 mm, largura do ventrículo esquerdo 7.0 ± 1,3 mm, altura do terceiro ventrículo 3,4 ± 0,8 mm, altura do hemisfério cerebral direito 39,5 ± 2,0 mm e altura do hemisfério cerebral esquerdo 40,2 ± 2,6 mm. As médias das medidas ventriculares foram maiores em cães acima de 11 anos de idade (p < 0,05). Contudo, a relação entre altura ventricular e altura cerebral não revelou diferenças entre grupos etários, sexo ou antímeros. Além disso, nenhuma imagem revelou ventrículos fusionados. Assim, os dados do presente estudo podem auxiliar na interpretação das dimensões ventriculares em cães da raça Poodle acima dos sete anos de idade.

Morphometry and skeletopy of kidneys and renal vessels in Alouatta guariba clamitans (Primates: Atelidae): case reports.

Various animal models are used for research; however, non-human primates are well suited for biomedical research owing to their genetic homology with humans. The objective of this research was the anatomical characterization of red howler's kidneys in view of the scarcity of information in the literature. Protocols were approved by the Committee for Ethics in the Use of Animals at the Federal Rural University of Rio de Janeiro (number 018/2017). The study was conducted at the Laboratory of Teaching and Research in Domestic and Wild Animal Morphology, Federal Rural University of Rio de Janeiro. Specimens of Alouatta guariba clamitans were collected from the Serra dos Órgãos National Park road in Rio de Janeiro and subsequently frozen. Four adult cadavers (two males and two females) were used, identified, and injected with a 10% formaldehyde solution. Later, the specimens were dissected, and measurements and topography of the kidneys and renal vessels were recorded. The kidneys of A. g. clamitans resemble a "bean seed," with a smooth surface. The longitudinal section shows two distinct regions, cortical and medullary; in addition, the kidneys are unipyramidal. The renal arteries emerged from the abdominal aorta as a single vessel posterior to the renal veins. The renal veins drained directly into the caudal vena cava as a single vessel in all specimens.

Vários modelos animais são usados para pesquisa, no entanto, primatas não humanos são adequados para pesquisas biomédicas devido à sua homologia genética com humanos. O objetivo desta pesquisa foi a caracterização anatômica dos rins do Bugio, tendo em vista a escassez de informações na literatura. Os protocolos foram aprovados pelo Comitê de Ética no Uso de Animais da Universidade Federal Rural do Rio de Janeiro (número 018/ 2017). O estudo foi realizado no Laboratório de Ensino e Pesquisa em Morfologia de Animais Domésticos e Silvestres da Universidade Federal Rural do Rio de Janeiro. Espécimes de Alouatta guariba clamitans foram coletados da estrada para o Parque Nacional da Serra dos Órgãos no Rio de Janeiro, e posteriormente congelados. Foram utilizados quatro cadáveres adultos (dois machos e duas fêmeas), identificados e injetados com solução de formaldeído a 10%. Os rins de A. g. clamitans assemelham-se a uma "semente de feijão", com superfície lisa. Ao corte longitudinal apresenta duas regiões distintas, cortical e medular, além disso, apresenta-se unipiramidal. As artérias renais emergiram da aorta abdominal como um único vaso, posteriormente às veias renais. As veias renais drenaram diretamente para a veia cava caudal como um único vaso em todos os espécimes.

Factors associated with the incidence and worsening of back pain during the first wave of COVID-19 in Brazil. / Fatores associados à incidência e à piora do problema de coluna durante a primeira onda da COVID-19 no Brasil.

The article aims to estimate the incidence and worsening of back pain (BP) during the first wave of COVID-19 in Brazil, as well as to investigate demographic, socioeconomic factors and associated changes in living conditions. ConVid - Behavior Research, applied between April and May 2020, was used as data source. The number and distribution of respondents who developed BP and those who had a worsening of the preexisting problem, their 95% confidence intervals and Pearson's Chi-square test were estimated. The odds ratio of developing BP or worsening a preexisting problem was also estimated using multiple logistic regression models. Pre-existing BP was reported by 33.9% (95%CI 32.5-35.3) of respondents and more than half (54.4%; 95%CI 51.9-56.9) had worsened. The cumulative incidence of BP in the first wave of the pandemic was 40.9% (95%CI 39.2-42.7). Being a woman, the perceived increase in housework and the frequent feeling of sadness or depression were associated with both outcomes. Socioeconomic factors were not associated with any of outcome. The high incidence and worsening of BP during the first wave reveal the need for studies in more recent periods, given the long duration of the pandemic.

O artigo tem como objetivo estimar a incidência e o agravamento do problema de coluna (PC) durante a primeira onda da COVID-19 no Brasil, bem como investigar os fatores demográficos, socioeconômicos e as mudanças nas condições de vida associadas. Utilizou-se a ConVid - Pesquisa de Comportamentos, realizada entre abril e maio de 2020, como fonte de dados. Estimou-se o número e a distribuição dos entrevistados que desenvolveram PC e a dos que tiveram agravamento no problema preexistente, seus intervalos de 95% de confiança e o teste qui-quadrado de Pearson. Estimou-se também a razão de chance de desenvolver PC ou ter piora de problema preexistente por meio de modelos de regressão logística múltipla. O PC preexistente foi reportado por 33,9% (IC95% 32,5-35,3) dos entrevistados e mais da metade (54,4%; IC95% 51,9-56,9) teve piora do quadro. A incidência cumulativa de PC na primeira onda da pandemia foi de 40,9% (IC95% 39,2-42,7). Ser mulher, o aumento percebido do trabalho doméstico e o sentimento frequente de tristeza ou depressão foram associados a ambos os desfechos. Os fatores socioeconômicos não foram associados a nenhum dos desfechos. A alta incidência e agravamento do PC durante a primeira onda revelam a necessidade de estudos em períodos mais recentes, dada a longa duração da pandemia.

The habit of drinking and driving in Brazil: National Survey of Health 2013 and 2019.

OBJECTIVE: To assess factors associated with the habit of drinking and driving and estimating the variations in the prevalence of this behavior in 2013 and 2019, considering information from the two editions of the Pesquisa Nacional de Saúde (PNS - National Survey of Health). METHODS: PNS is a nationwide cross-sectional home-based study. In 2013 and 2019, 60,202 and 85,854 individuals were interviewed, respectively. To assess the association between the indicator "drinking and driving" and the study variables, crude and adjusted odds ratios (ORs) were estimated using logistic regression models. To compare the prevalence between the studied years, a Pearson's chi-squared test adjusted by the Rao-Scott correction (which considers the effect of the sampling plan) and converted into an F statistic, tested at a 5% significance level, was used. RESULTS: The prevalence of drinking and driving was higher among men in 2013 (27.4%; 95%CI 25.6-29.3%) and 2019 (20.5%; 95%CI 19.4-21.7%) than among women (11.9%; 95%CI 9.9-14.2% and 7.2%; 95%CI 6.7-9.0%, respectively). Inidviduals aged 30 to 39, who lived without a partner, in rural areas, and were motorcycle drivers had significantly higher estimates. Men with higher income had higher prevalence of drinking and driving. From 2013 to 2019, the act of drinking and driving significantly decreased. Regarding traffic accidents, ORs were significant (p < 0.01) in the studied years for both men and women. DISCUSSION: Results show the need to continue policies to monitor blood alcohol level and traffic education, with specific actions directed to rural areas and motorcycle drivers.
