Larvicidal efficacies of plants from Midwestern Brazil: melianodiol from Guarea kunthiana as a potential biopesticide against Aedes aegypti.

A total of 36 ethanol extracts from different anatomical parts of 27 plant species (18 families), native to the Pantanal and Cerrado biomes in Midwest Brazil, was assessed for their effect against Aedes aegypti larvae, the vector of dengue, hemorrhagic dengue, Zika and chikungunya fevers. Only the extract obtained from seeds of Guarea kunthiana (Meliaceae) proved active (LC50 = 169.93 µg/mL). A bioassay-guided investigation of this extract led to the isolation and identification of melianodiol, a protolimonoid, as the active constituent (LC50 = 14.44 mg/mL). Meliantriol, which was also obtained from the bioactive fraction, was nevertheless devoid of any larval toxicity, even at the highest concentration tested (LC50 > 100.0 mg/mL). These results indicate that the larvicidal activity of melianodiol stems from the presence of the carbonyl moiety at C-3 in the 21,23-epoxy-21,24,25-trihydroxy-tirucall-7-ene-type skeleton. The structures of both protolimonoids were established on the basis of spectral methods (1H and 13C NMR and MS). This is the first report on the toxicity of melianodiol against Ae. aegypti larvae. Based on the results, melianodiol can be regarded as a potential candidate for use as an ecologically sound biocontrol agent for reducing the larval population of this vector.

Use of electronic health records and primary health care accessibility according to data from the third cycle of the PMAQ-AB. / Uso de prontuário eletrônico e parâmetros de acesso e acolhimento segundo dados do terceiro ciclo do PMAQ-AB.

The use of electronic health records (EHR) in primary healthcare (PHC) aims for better integration of services and care quality. One of most the critical points of Brazilian PHC is access. This article aims to analyze, through data from the third evaluation cycle of the Brazilian Program for Improving Access and Quality of Primary Care (PMAQ-AB), the relationship between the use of electronic health records and the parameters of access of the participant teams. Cross-sectional analytical study with secondary data. Data from 38,865 primary care teams, 30,346 health units and 140,444 interviewed users were evaluated. The use of EHR was associated with greater care for non-programmed demands (OR 1.664; 95%CI 1.485-1.866), risk and vulnerability assessment (OR 1.329; 95%CI 1.122-1.574) and use of protocols for clinical conducts (OR 1.656; 95%CI 1.530-1.793), in addition to a greater possibility of scheduling consultation by telephone (OR 3.179; 95%CI 3.030-3.335). Services using EHR are more likely to be the patients first contact (OR 1.226; 95%CI 1.171-1.283) and to be sought when facing urgent health problem (OR 1.198; 95%CI 1.161-1.236). The results point to a concrete possibility of improving access through computerization.

Factors associated with interprofessional collaboration in Primary Health Care: a multilevel analysis.

Working with an interprofessional focus is increasingly necessary, in view of the growing complexity of the population's health needs. This study aims to assess interprofessional collaboration and the teamwork climate in primary health care (PHC) and determine whether there is a relationship between these two variables. The AITCS-II instrument was used to measure interprofessional collaboration, while to diagnose teamwork climate, the ECTE instrument was used, a version adapted to the SUS context of the Teamwork Climate Inventory instrument. These two instruments were applied online together with a questionnaire for the sociodemographic characterization of the 544 participants, who belonged to 97 Family Health Strategy (FHS) teams in a Brazilian municipality. The obtained data were submitted to a multilevel analysis. A positive correlation was observed between interprofessional collaboration and three of the four teamwork climate factors. The better the work climate, the better the interprofessional collaboration in the corresponding team, and this characteristic stands out in relation to other individual analyzed characteristics.

Analysis of high-intensity interval training on bone mineral density in an experimental model of type 2 diabetes.

PURPOSE: To analyze the effect of high-intensity interval training (HIIT) on bone mineral density (BMD) in a model of type 2 diabetes mellitus. METHODS: Thirty-two male, adult, 12-week-old rats (Rattus norvegicus), of the Wistar lineage, were used. The animals induced to the experimental model received a high fat diet for 10 days and, after that period, intraperitoneal injection of streptozotocin (40 mg·kg-1), dissolved in 20 mmol·L-1 sodium citrate solution (pH = 4.5). The experimental group of diabetes was formed by the animals that, 48 h after the injection of streptozotocin, had fasting blood glucose > 250 mg·dL-1). The animals were randomly divided into four groups with eight animals each: HIIT experimental diabetes; HIIT control; sedentary experimental diabetes and sedentary control. The animals in the HIIT group performed an aerobic exercise protocol on a treadmill inclined at an angle of 15° to the horizontal, with interspersed intensity. Five weekly sessions, lasting 49 min each, were held for 6 weeks. The analysis of cortical bone density (CBD) and BMD were performed by X-ray images using the In-Vivo Xtreme II/Bruker system. RESULTS: For CBD and BMD, when comparing diabetes and control groups, a significant difference was seen between groups in relation to HIIT (p = 0.007). Animals submitted and not submitted to HIIT in the same group showed a significant difference between groups in relation to diabetes (p < 0.001). CONCLUSIONS: The HIIT experimental diabetes group had increased CBD and BMD in comparison with the sedentary experimental diabetes group.

Analysis of the temporal trend of mortality from sickle cell anemia in Brazil.

OBJECTIVES: To analyze the temporal trend of mortality from sickle cell anemia in Brazil, by region, in the period 1997-2017. METHODS: epidemiological study, with an ecological design, with a temporal trend, carried out with data from the Mortality Information System. For descriptive analysis, absolute and relative frequencies were used. In the correlation analysis, the ANOVA test was used, followed by Tukey's post-test. The temporal trend was obtained using the cubic polynomial regression test. RESULTS: 6,813 deaths from sickle cell anemia were registered. Brown individuals (50.87%) were more frequent, with a predominance of males (50.4%), aged between 25 and 34 years and a higher incidence of deaths in the Midwest (0.25/100 thousand inhabitants). The time curve showed an increasing trend of deaths in the country between 1997 and 2015 (R2 = 0.98). CONCLUSIONS: sickle cell anemia showed increasing mortality in the 21 years analyzed and alerts health professionals and managers.

Architectural and communications barriers to access to primary health care in Brazil: an analysis based on the first national census of primary health care centers, 2012. / Barreiras arquitetônicas e de comunicação no acesso à atenção básica em saúde no Brasil: uma análise a partir do primeiro Censo Nacional das Unidades Básicas de saúde, 2012.

OBJECTIVE: to analyze the results of the National Census of Primary Health Care Centers with regard to architectural and communication barriers in Primary Health Care throughout Brazil. METHODS: this was a cross-sectional study based on data from the first National Census of Primary Health Care Centers conducted between May and October 2012. RESULTS: the Northern region had the lowest rates of adequacy; although the Southeast region had the best rates when compared to the country's other regions, they were nevertheless unsatisfactory, since for many items adequacy was still below 50%; the items relating to accessibility by people with disabilities (5.7 to 34.2%) and/or the illiterate (0.1 to 27.4%) had very low scores. CONCLUSION: the majority of services evaluated had architectural and communication barriers, hindering access to health services by disabled, illiterate or elderly people; the importance of allocating resources to reduce iniquities and improve access is stressed.

Construction and validation of an instrument for the assessment of care provided to people with suicidal behavior.

OBJECTIVE: To develop and validate an instrument for evaluating primary health care professionals' assistance to people with suicidal behavior. METHODS: This was a methodological study, which began with a literature review, followed by the elaboration of an instrument. In its first version, the instrument had 34 items, divided into four domains: "professional characterization," "professional perception " "professional knowledge/abilities," and "organization of the care network." Contents were validated using the Delphi method. Semantic analysis was performed by college-educated primary health care professionals in greater and lesser strata of ability. For internal consistency analysis, Cronbach's alpha coefficient was calculated. The study was conducted between January and December 2017. RESULTS: After four Delphi rounds, the instrument was successfully validated. In its final form, it is comprised of 50 items, divided into five domains: "professional characterization," "professional sensibility," "professional experience," "professional knowledge/abilities," and "organization of the care network." Questions belonging to the last four domains have answers on a five-point Likert scale. In the semantic analysis, 93.6% of the evaluations were "good" and "very good." The instrument's general Cronbach alpha was 0.90. CONCLUSIONS: The final version of the instrument was able to fulfill its objectives. It is useful as a support for epidemiological research and planning of health actions. The evaluation of professional approaches to suicidal behavior is crucial for the organization of suicide assistance services in primary health care, and for the integration of services provided by different care units.

Occupational stress and coping strategies of nursing staff in times of Covid-19

Introduction: The increase in the workload of health professionals and the degree of complexity of patients, attribute greater risk to psychosocial stress. Objective: To evaluate the associations between occupational stress, quality of life at work, and coping strategies by the hospital nursing team during the COVID-19 pandemic. Methods: Cross sectional, quantitative study with convenience sampling, data collection from August to December 2020; in two units of the private hospital network, with sociodemographic, occupational and health questionnaires; visual analogue scale for assessing quality of life at work; Demand-Control-Support (DCS); Occupational Coping Scale. Results: The total sample consisted of 196 nursing professionals. There was significant certainty (negative, however, the dimension "Demand" of the DCS and QWL (<0.001, r=-0.367). Control over work-related work has a significant quality (but the "Control" dimension of the DCS and QWL (=0.025, r=0.160); and significantly negative, however, between the "Social Support" dimension of DCS and "Negative Equivalence" of Coping (p=0.003, r=-0.2013). Conclusion: The findings of this study allowed the correlation between occupational stress, coping and quality of life at work, showing that the lower the social support, the greater the use of avoidance strategies and consequently decline in quality of life at work. They also allowed us to identify the coping strategies used by the nursing staff and quality of life at work in the face of occupational stress during the COVID-19 pandemic.

A diagnosis of pulmonary tuberculosis and drug resistance among inmates in Mato Grosso do Sul, Brazil.

INTRODUCTION: High endemic levels of pulmonary tuberculosis in prisons result from overcrowding, limited access to healthcare, delayed diagnosis, sustained transmission owing to poor control measures, and multidrug resistance. This study evaluated locally implemented measures for early pulmonary tuberculosis diagnosis and evaluated resistance to anti-tuberculosis drugs. METHODS: This transversal study employed data from the Mato Grosso do Sul State Tuberculosis Control Program obtained from 35 correctional facilities in 16 counties for 2 periods (2007-2010 and 2011-2014). RESULTS: Statewide prevalence (per 100,000) was 480.0 in 2007 and 972.9 in 2014. The following indicators showed improvement: alcohol-acid-fast bacillus testing (from 82.7% to 92.9%); cultures performed (55.0% to 81.8%); drug susceptibility testing of positive cultures (71.6% to 62.4%); and overall drug susceptibility testing coverage (36.6% to 47.4%). Primary and acquired resistance rates for 2007-2014 were 21.1% and 30.0%, respectively. Primary and acquired multidrug resistance rates were 0.3% and 1.3%, respectively. CONCLUSIONS: Prevalence rates increased, and laboratory indicators improved as a result of capacity building and coordination of technical teams and other individuals providing healthcare to inmates. Resistance rates were high, thereby negatively affecting disease control.

Pulmonary oxidative stress in diabetic rats exposed to hyperoxia.

PURPOSE:: To evaluate the pulmonary oxidative stress in diabetic rats exposed to hyperoxia for 90 minutes. METHODS:: Forty male Wistar rats were divided into four groups, each one containing 10 animals, according to the oxygen concentration to which they were exposed: 21%, 50%, 75% and 100% (hyperoxia). In each group five animals were randomly induced to diabetes by means of at a dose of 55 mg/kg of streptozotocin (STZ). RESULTS:: Seventy two hours after diabetes induction, a significant difference was seen in blood glucose in the experimental groups in comparison with the control. In the experimental groups a significant difference was observed in the concentration of malondialdehyde (MDA) in lung tissue and blood plasma (p<0.05), except the 50% group. In the control group, significant differences in the MDA concentration in plasma and lung tissue were also observed (p<0.05), except the 75% group. The MDA concentration in lung tissue in comparison with the diabetic and non-diabetic groups showed a significant difference in the 21% group; however, no difference was seen in the 75 and 100% groups. CONCLUSION:: In diabetic animals high oxygen concentrations (75 and 100%) do not appear to exert deleterious effects on lipid peroxidation in lung tissue.

Analysis of high-intensity interval training on bone mineral density in an experimental model of type 2 diabetes

Purpose: To analyze the effect of high-intensity interval training (HIIT) on bone mineral density (BMD) in a model of type 2 diabetes mellitus. Methods: Thirty-two male, adult, 12-week-old rats (Rattus norvegicus), of the Wistar lineage, were used. The animals induced to the experimental model received a high fat diet for 10 days and, after that period, intraperitoneal injection of streptozotocin (40 mg·kg­1), dissolved in 20 mmol·L­1 sodium citrate solution (pH = 4.5). The experimental group of diabetes was formed by the animals that, 48 h after the injection of streptozotocin, had fasting blood glucose > 250 mg·dL­1). The animals were randomly divided into four groups with eight animals each: HIIT experimental diabetes; HIIT control; sedentary experimental diabetes and sedentary control. The animals in the HIIT group performed an aerobic exercise protocol on a treadmill inclined at an angle of 15° to the horizontal, with interspersed intensity. Five weekly sessions, lasting 49 min each, were held for 6 weeks. The analysis of cortical bone density (CBD) and BMD were performed by X-ray images using the In-Vivo Xtreme II/Bruker system. Results: For CBD and BMD, when comparing diabetes and control groups, a significant difference was seen between groups in relation to HIIT (p = 0.007). Animals submitted and not submitted to HIIT in the same group showed a significant difference between groups in relation to diabetes (p < 0.001). Conclusions: The HIIT experimental diabetes group had increased CBD and BMD in comparison with the sedentary experimental diabetes group.

Abstract Objective To cross-culturally translate and adapt the Spanish Older Adults Socio-familial Evaluation Scale (Gijón Scale) to the Brazilian context. Methods A methodological procedure of cross-cultural adaptation with translation (Spanish-Portuguese), back-translation (Portuguese-Spanish), evaluation of semantic, idiomatic, experimental, and conceptual equivalences, and pretest of the Brazilian version in a sample of 30 older adults. For the concordance analysis, proportionality and the Kappa Cohen-Fleiss index (κ) were measured. In addition, internal consistency was confirmed by Cronbach's alpha. Results Translations (T1 and T2), back-translations (RT1 and RT2), and evaluations of the synthesis version (T12) were carried out by a Committee of Experts, and a neutral judge ensured the evaluative essence of the original version of the scale in T12. The evaluation of the 34 components of T12 showed semantic (100%) and idiomatic (94%) adequacy, and adequacy greater than 70% for experimental and conceptual equivalences. There was almost perfect concordance among the experts of the Committee: semantics (κ=0.95), idiomatic (κ=0.97), experimental (κ=0.98), and conceptual (κ=0.99). The T12 pretest resulted in substantial reliability of the instrument with a Cronbach's alpha of 0.77. Conclusion The present study ensures the cross-cultural adaptation of the Socio-familial Evaluation Scale to the context of the older person living in Brazil. The equivalence evaluation resulted in almost perfect concordance among experts. The target audience did not report difficulties in understanding the assertions of the scale. The instrument proved to be reliable considering the Cronbach's alpha obtained. After validating the scale, an ongoing study, a reliable instrument will be made available for tracking the socio-familial situation of older adults in the Brazilian context.

The influence of enriched environment on spatial memory in Swiss mice of different ages.

The objective of this study was to evaluate the influence of enriched environment on spatial memory acquisition in mice of three different age groups. Weanling, young, and young adult female Swiss mice were housed in a standard control or enriched environment for 50 days, and their spatial memory was tested with the Morris Water Maze. We did not observe an experimental effect for spatial memory acquisition, and there was neither an effect of time of analysis nor an interaction between experimental group and time of analysis. Regarding effects of experimental group and training day in relation to latency in finding the hidden platform, we did find an effect in the experimental young adult mice group (p = 0.027), but there was no interaction between these factors in all three groups. Based on these findings environmental enrichment did not enhance spatial memory acquisition in female Swiss mice in the tested age groups.

Renal biomarkers of male and female Wistar rats (Rattus norvegicus) undergoing renal ischemia and reperfusion.

PURPOSE: To investigate biomarkers of acute renal injury in Wistar rats, subjected to left renal ischemia for 10 minutes, and then compare reperfusion at 24 hours, and at 5, 7, 14 and 21 days after the procedure. METHODS: Eight female and male rats between 60 and 81 days old were used in the Central Animal Facility of the UFMS. Assessed biomarkers included urine protein, urea, creatinine, glucose, sodium, potassium, urine alkaline phosphatase and gamma-glutamyl transferase activities, and protein-to-creatinine ratio; and in serum: urea, creatinine, sodium and potassium, fractional excretion of sodium, potassium, urine flow and creatinine clearance. RESULTS: Greater variance was observed in the parameters at 24 hours and at five days (p<0.05) after reperfusion. On the 21st day, these parameters approximated those obtained for the control group. CONCLUSIONS: Renal ischemia for 10 minutes was sufficient to raise urine levels of protein, glucose, fractional excretion of potassium, urea, creatinine clearance, urine activity of gamma-glutamyltransferase and alkaline phosphatase enzymes in the first 24 hours, up to five days after reperfusion, which may indicate risk of acute kidney injury, according to the RIFLE classification.

Relação entre internações, óbitos por doenças do aparelho circulatório e estrutura dos serviços / Relationship between hospitalizations, deaths and service structure

Resumo Introdução A estruturação dos serviços de saúde é um elemento fundamental para dar respostas à carga de doenças crônicas. Objetivo Analisar a relação entre internações e óbitos pelas doenças do aparelho circulatório e a estrutura nos serviços de saúde. Método Estudo transversal desenvolvido em estado do Centro-Oeste brasileiro, região de saúde composta de 17 municípios e 1.112.792 habitantes. Foram analisadas as dimensões demográfica, epidemiológica e de estrutura de saúde pela estatística descritiva e correlação linear de Pearson. Resultados A taxa da mortalidade por doenças do aparelho circulatório foi de 29,49%, superior aos achados no país e no Centro-Oeste. Houve correlação significativa entre internação por doenças isquêmicas do coração e número de leitos e entre internação por doenças do aparelho circulatório e número de serviços especializados para cada 10 mil habitantes. Conclusão As diferenças encontradas entre internações e a existência dos serviços especializados e leitos indicam que a população que reside em municípios com estrutura de serviços complexa possui mais acesso aos serviços e às internações. Os resultados demonstram que deve haver mais cuidado na conformação e oferta de serviços na Rede de Atenção à Saúde para as doenças do aparelho circulatório, visando assegurar equidade no acesso da população aos serviços pactuados.

Abstract Background The structuring of health services is a fundamental element to respond to the burden of chronic diseases. Objective To analyze the relationship between hospitalizations and deaths due to diseases of the circulatory system and the structure in health services. Method A cross-sectional study developed in the state of the Brazilian central-west was carried out with a health region composed of 17 municipalities and 1,112,792 inhabitants. The demographic, epidemiological and health structure dimensions were analyzed using descriptive statistics and Pearson's linear correlation. Results The mortality rate due to diseases of the circulatory system was 29.49%, higher than the findings in the country and in the center-west. There was a significant correlation between hospitalization for ischemic heart diseases and number of beds, and between hospitalization for diseases of the circulatory system and number of specialized services for each 10,000 inhabitants. Conclusion The differences found between hospitalizations and the existence of specialized services and beds indicate that the population that lives in municipalities with a complex service structure has more access to services and hospitalizations. The results demonstrate that there must be greater care in the conformation and offer of services in the Health Care Network for diseases of the circulatory system, aiming to ensure equity in the population's access to the agreed services.

Anti-annexin V autoantibodies and vascular abnormalities in systemic sclerosis: a longitudinal study

Abstract Background: Annexins are a group of conserved proteins which exert several regulatory functions on various cellular activities. Increased frequency and levels of antibodies against annexin V have already been observed in several autoimmune diseases including systemic sclerosis (SSc), but their role as a vascular biomarker is unknown. The aim of this study was to determine the serum levels and the dynamical behavior of anti-annexin V antibodies over a 24 months follow-up in patients with SSc. Methods: In this bicentric cross-sectional study, 70 patients with SSc were consecutively selected from March 2016 to April 2017. Demographic and clinical features, including the presence of active DUs, were collected. Serum anti-annexin V IgG and IgM antibodies were measured at baseline and after 6, 12 and 24 months of follow-up. Videocapillaroscopy was performed in all patients. Results: Among the 70 SSc patients included anti-annexin V IgG was found in 11 patients (15.7%) (range of 15.88-39.48 U/mL) and anti-annexin V IgM in 10 patients (14.3%) (range of 14.16-22.69 U/mL) at baseline. During follow-up, the number of patients who were positive for anti-annexin V IgG and IgM remained stable over 24 months. Among the patients with positive anti-annexin V IgG at baseline the frequency of patients with necrosis or amputation of extremities, forced vital capacity less than 70% and pulmonary arterial hypertension (PAH) was significantly higher than in patients with negative anti-annexin V IgG antibodies. Patients with anti-annexin V IgG had also a higher Raynaud's Condition Score and a higher Health Assessment Questionnaire Disability Index (HAQ-DI) than patients without these antibodies at baseline. Patients with positive anti-annexin V IgM at baseline presented a higher frequency of PAH, compared to those with negative anti-annexin V IgM at baseline. Conclusions: Anti-annexin V antibodies are stable and do not change their positivity during a 24 month follow-up in SSc patients. Anti-annexin V IgG was associated with more severe interstitial lung involvement and digital microangiopathy, and patients with anti-annexin V IgG or IgM had a higher occurrence of PAH indicating an association of these biomarker with more severe disease.(AU)
