The intersection of race/ethnicity and socioeconomic status: inequalities in breast and cervical cancer mortality in 20,665,005 adult women from the 100 Million Brazilian Cohort.

OBJECTIVES: There is limited evidence regarding the impact of race/racism and its intersection with socioeconomic status (SES) on breast and cervical cancer, the two most common female cancers globally. We investigated racial inequalities in breast and cervical cancer mortality and whether SES (education and household conditions) interacted with race/ethnicity. DESIGN: The 100 Million Brazilian Cohort data were linked to the Brazilian Mortality Database, 2004-2015 (n = 20,665,005 adult women). We analysed the association between self-reported race/ethnicity (White/'Parda'(Brown)/Black/Asian/Indigenous) and cancer mortality using Poisson regression, adjusting for age, calendar year, education, household conditions and area of residence. Additive and multiplicative interactions were assessed. RESULTS: Cervical cancer mortality rates were higher among Indigenous (adjusted Mortality rate ratio = 1.80, 95%CI 1.39-2.33), Asian (1.63, 1.20-2.22), 'Parda'(Brown) (1.27, 1.21-1.33) and Black (1.18, 1.09-1.28) women vs White women. Breast cancer mortality rates were higher among Black (1.10, 1.04-1.17) vs White women. Racial inequalities in cervical cancer mortality were larger among women of poor household conditions, and low education (P for multiplicative interaction <0.001, and 0.02, respectively). Compared to White women living in completely adequate (3-4) household conditions, the risk of cervical cancer mortality in Black women with 3-4, 1-2, and none adequate conditions was 1.10 (1.01-1.21), 1.48 (1.28-1.71), and 2.03 (1.56-2.63), respectively (Relative excess risk due to interaction-RERI = 0.78, 0.18-1.38). Among 'Parda'(Brown) women the risk was 1.18 (1.11-1.25), 1.68 (1.56-1.81), and 1.84 (1.63-2.08), respectively (RERI = 0.52, 0.16-0.87). Compared to high-educated White women, the risk in high-, middle- and low-educated Black women was 1.14 (0.83-1.55), 1.93 (1.57-2.38) and 2.75 (2.33-3.25), respectively (RERI = 0.36, -0.05-0.77). Among 'Parda'(Brown) women the risk was 1.09 (0.91-1.31), 1.99 (1.70-2.33) and 3.03 (2.61-3.52), respectively (RERI = 0.68, 0.48-0.88). No interactions were found for breast cancer. CONCLUSION: Low SES magnified racial inequalities in cervical cancer mortality. The intersection between race/ethnicity, SES and gender needs to be addressed to reduce racial health inequalities.

Climate change facilitated the early colonization of the Azores Archipelago during medieval times.

Humans have made such dramatic and permanent changes to Earth's landscapes that much of it is now substantially and irreversibly altered from its preanthropogenic state. Remote islands, until recently isolated from humans, offer insights into how these landscapes evolved in response to human-induced perturbations. However, little is known about when and how remote systems were colonized because archaeological data and historical records are scarce and incomplete. Here, we use a multiproxy approach to reconstruct the initial colonization and subsequent environmental impacts on the Azores Archipelago. Our reconstructions provide unambiguous evidence for widespread human disturbance of this archipelago starting between 700-60+50 and 850-60+60 Common Era (CE), ca. 700 y earlier than historical records suggest the onset of Portuguese settlement of the islands. Settlement proceeded in three phases, during which human pressure on the terrestrial and aquatic ecosystems grew steadily (i.e., through livestock introductions, logging, and fire), resulting in irreversible changes. Our climate models suggest that the initial colonization at the end of the early Middle Ages (500 to 900 CE) occurred in conjunction with anomalous northeasterly winds and warmer Northern Hemisphere temperatures. These climate conditions likely inhibited exploration from southern Europe and facilitated human settlers from the northeast Atlantic. These results are consistent with recent archaeological and genetic data suggesting that the Norse were most likely the earliest settlers on the islands.

Content analysis of the nursing diagnosis of ineffective peripheral tissue perfusion in patients with diabetic foot.

AIM: To analyse the content of the nursing diagnosis ineffective peripheral tissue perfusion in patients with diabetic foot. DESIGN: A methodological study with a quantitative approach was performed. METHODS: The analysis was performed between January and May 2021 by 34 nurses with clinical/theoretical/research experience with diabetes or nursing diagnoses. These nurses evaluated the relevance, clarity and precision of 12 diagnosis-specific etiological factors, 22 clinical indicators and their conceptual and operational definitions. FINDINGS: All 12 etiological factors analysed were considered relevant to diagnostic identification. However, five showed inconsistencies regarding the clarity or precision of the operational definitions, requiring adjustments. Regarding the 22 clinical indicators evaluated, all of them presented a Content Validity Index (CVI) that was statistically significant. However, in the indicators, the colour does not return to lowered limb after 1 min of leg elevation, and cold foot had Content Validity Index (CVI) <0.9 regarding relevance and accuracy of operational definitions. CONCLUSIONS: Twelve etiological factors and 22 clinical indicators were validated. Thus, this study revealed new and relevant aspects characterising peripheral perfusion in patients with diabetic foot that have not yet been clinically validated. IMPLICATIONS FOR NURSING PRACTICE: This study contributes to support the professional practice of nurses through the early identification of etiological factors and clinical indicators in persons with diabetic foot. As a proposal, we suggest the inclusion of new defining characteristics and related factors for the nursing diagnosis ineffective peripheral tissue perfusion in the NANDA-I taxonomy. IMPACT: The research highlights new and relevant aspects such as etiological factors and clinical indicators to characterise peripheral perfusion in patients with diabetic foot. Based on these findings, clinical validation is recommended to confirm the relevance of the proposed elements in the population studied for greater reliability and improved diagnostic assessment for the professional practice of nurses. REPORTING METHOD: EQUATOR guidelines were adhered to using the GRRAS checklist for reporting reliability and agreement studies. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Effect of cashew nut flour on hematological parameters of children living with HIV.

Aim: To assess the effect of cashew nut flour on the hematological parameters of children living with HIV-AIDS. Method: A 32-week randomized, blind clinical trial conducted at a specialized outpatient clinic. Children aged 2-12 years were allocated to intervention groups (IGs) (n = 11) receiving 12 g/day of cashew nut flour and control groups (CGs) (n = 9) receiving 12 g/day of carboxymethyl cellulose. Parameters of erythrocytes, leukocytes, platelets, and lipid profiles were evaluated. Results: In the IG, the elevation and reduction of leukocyte and lipid profile biomarkers, respectively, were not statistically significant (p > 0.05). A clinically and statistically significant increase in mean corpuscular hemoglobin concentration was observed in the CG (p = 0.018), with a large effect size (Cohen's d = 0.9). There were no statistically significant changes in platelet counts among participants (p = 0.18). The effect size for white blood cell count, low-density lipoprotein cholesterol, very low-density lipoprotein, and triglycerides was moderate in the IG compared to the CG. Conclusion: Cashew nut flour supplementation may increase levels of leukocytes and lipid profile parameters in children living with HIV. Brazilian Clinical Trials Registry (REBEC): U1111.1276.6591.

Optimization of Biodiesel Production Process Using MoO3 Catalysts and Residual Oil: A Comprehensive Experimental 23 Study.

The study aimed to utilize MoO3 catalysts, produced on a pilot scale via combustion reaction, to produce biodiesel from residual oil. Optimization of the process was conducted using a 23 experimental design. Structural characterization of the catalysts was performed through X-ray diffraction, fluorescence, Raman spectroscopy, and particle size distribution analyses. At the same time, thermal properties were examined via thermogravimetry and differential thermal analysis. Catalytic performance was assessed following process optimization. α-MoO3 exhibited a monophasic structure with orthorhombic phase, whereas α/h-MoO3 showed a biphasic structure. α-MoO3 had a larger crystallite size and higher crystallinity, with thermal stability observed up to certain temperatures. X-ray fluorescence confirmed molybdenum oxide predominance in the catalysts, with traces of iron oxide. Particle size distribution analyses revealed polymodal distributions attributed to structural differences. Both catalysts demonstrated activity under all conditions tested, with ester conversions ranging from 93% to 99%. The single-phase catalyst had a long life cycle and was reusable for six biodiesel production cycles. The experimental design proved to be predictive and significant, with the type of catalyst being the most influential variable. Optimal conditions included α-MoO3 catalyst, oil/alcohol ratio of 1/15, and a reaction time of 60 min, resulting in high biodiesel conversion rates and showcasing the viability of MoO3 catalysts in residual oil biodiesel production.

Tumor burden in patients with early and intermediate-stage hepatocellular carcinoma undergoing liver resection: a retrospective multicenter study on clinical and oncological outcomes.

BACKGROUND: According to the Barcelona Clinic Liver Cancer (BCLC) staging system, liver resection (LR) is recommended for early-stage (BCLC-A) hepatocellular carcinoma (HCC) but not for intermediate-stage (BCLC-B). This study aimed to assess the outcomes of LR in these patients using a subclassification tumour burden score (TBS). METHODS: All consecutive patients that underwent LR for BCLC-A and BCLC-B HCC between 01/2010 and 12/2020 in 4 tertiary referral centers were included. Clinical outcomes and overall survival (OS) were assessed in relation to TBS and BCLC stages. RESULTS: Among 612 patients included, 562 were classified as BCLC-A and 50 as BCLC-B. The incidence of overall postoperative complications (56.0 vs 41.5%, p = 0.053) and mortality (0 vs 1.6%, p = 1.000) were similar between BCLC-A and BCLC-B patients. OS was significantly higher for BCLC A/low TBS than BCLC B/low TBS (p = 0.009), while patients with medium and high TBS had similar OS, irrespective of BCLC stage (respectively p = 0.103 and p = 0.343). CONCLUSIONS: Patients with medium and high TBS had comparable OS and DFS, irrespective of BCLC A or B stage, and postoperative morbidity was comparable. These results highlight the need for refinement of the BCLC staging system, and LR could be considered for selected intermediate stage (BCLC-B) according to the tumour burden.

In vitro characterization of hydroxyapatite and cobalt ferrite nanoparticles compounds and their biocompatibility in vivo.

Bioactive materials in combination with antibiotics have been widely developed for the treatment of bone infection. Thus, this work aims to characterize six biomaterials formulated with different concentrations of hydroxyapatite and cobalt ferrite nanoparticles, in addition to the antibiotic ciprofloxacin, using X-ray diffraction (XRD), scanning electron microscopy (SEM), and the antibiotic diffusion test on agar. Furthermore, in vivo biocompatibility and the reabsorption process of these materials were analyzed. XRD showed that both hydroxyapatite and cobalt ferrite present high crystallinity. The photomicrographs obtained by SEM revealed that composites have a complex surface, evidenced by the irregular arrangement of the hydroxyapatite and cobalt ferrite granules, besides demonstrating the interaction between their components. The antibiotic-diffusion test showed that all biomaterials produced an inhibition halo in Staphylococcus aureus cultures. For the biocompatibility study, composites were surgically implanted in the dorsal region of rabbits. At 15, 30, 70, and 100 days, biopsies of the implanted regions were performed. The biomaterials were easily identified during histological analysis and no significant inflammatory process, nor histological signs of toxicity or rejection by the adjacent tissue were observed. We can conclude that the biomaterials analyzed are biocompatible, degradable, and effective in inhibiting the in vitro growth of Staphylococcus aureus. Graphical abstract.

Interventions to obstructive long-term central venous catheter in cancer patients: a meta-analysis.

PURPOSE: The aim of this systematic review was to identify the interventions used to treat obstructive events, whether thrombotic or non-thrombotic, in long-term central venous catheters (LT-CVC) in cancer patients. METHODS: This review included clinical trials and observational studies reporting the drugs used to treat obstructive catheter events in cancer patients. The authors developed specific search strategies for CINAHL, Cochrane CENTRAL, LILACS, PubMed, Scopus, Web of Science, Google Scholar, Open Grey, and ProQuest. The authors evaluated methodological quality of included studies using criteria from Cochrane's Collaboration Tool and the Methodological Index for non-randomized studies (MINORS). The quality of evidence was analyzed by using GRADE's software. RESULTS: More than 9000 articles were found across the databases. After duplicates removed, the studies were selected in 2 phases. After that, only 15 studies were included. The drugs used to restoration of catheter function were urokinase (53.3%), alteplase (20%), tenecteplase (13.3%), reteplase (6.7%), recombinant urokinase (6.7%), and staphylokinase (6.7%). The results of meta-analysis of 14 studies showed an overall restoration rate of ~ 84%. The drug type meta-analysis demonstrates a success rate of ~ 84%, ~ 92%, and ~ 84% for urokinase, alteplase, and tenecteplase groups, respectively. The main methodological problem in included articles concerns the sample. The quality of evidence ranged from very low to high. CONCLUSION: The most common interventions used to treat thrombotic catheter occlusion in cancer patients were urokinase and alteplase. No evidence was found about the treatment for non-thrombotic occlusion, thus elucidating an important gap to be investigated.

Factors Associated With Body Image Perception Among Brazilian Students From Low Human Development Index Areas.

This study aimed to evaluate sociodemographic, behavioral, and individual factors associated with body image perception in a sample of adolescents from schools in low Human Development Index areas in Brazil. This cross-sectional study included 609 boys and 573 girls (aged 11-17 years). Body image perception (nine-silhouettes scale) and sociodemographic, behavioral, and individual variables were included. Multinomial logistic regression analysis was used. Most boys (76.9%) and girls (77.5%) were dissatisfied with their body image. Body mass index status and healthy body image evaluation were significantly associated with body image dissatisfaction in both boys and girls ( p < .001), and daily fruit consumption was associated with body image dissatisfaction only in boys ( p = .035). Education and health care focused on body image can pay special attention to young people from vulnerable areas with unhealthy nutritional status and focus on strategies that enable improving the perception of a healthy body and a healthy diet.

The role and utilisation of public health evaluations in Europe: a case study of national hand hygiene campaigns.

BACKGROUND: Evaluations are essential to judge the success of public health programmes. In Europe, the proportion of public health programmes that undergo evaluation remains unclear. The European Centre for Disease Prevention and Control sought to determine the frequency of evaluations amongst European national public health programmes by using national hand hygiene campaigns as an example of intervention. METHODS: A cohort of all national hand hygiene campaigns initiated between 2000 and 2012 was utilised for the analysis. The aim was to collect information about evaluations of hand hygiene campaigns and their frequency. The survey was sent to nominated contact points for healthcare-associated infection surveillance in European Union and European Economic Area Member States. RESULTS: Thirty-six hand hygiene campaigns in 20 countries were performed between 2000 and 2012. Of these, 50% had undergone an evaluation and 55% of those utilised the WHO hand hygiene intervention self-assessment tool. Evaluations utilised a variety of methodologies and indicators in assessing changes in hand hygiene behaviours pre and post intervention. Of the 50% of campaigns that were not evaluated, two thirds reported that both human and financial resource constraints posed significant barriers for the evaluation. CONCLUSION: The study identified an upward trend in the number of hand hygiene campaigns implemented in Europe. It is likely that the availability of the internationally-accepted evaluation methodology developed by the WHO contributed to the evaluation of more hand hygiene campaigns in Europe. Despite this rise, hand hygiene campaigns appear to be under-evaluated. The development of simple, programme-specific, standardised guidelines, evaluation indicators and other evidence-based public health materials could help promote evaluations across all areas of public health.

Indicators of social inequalities associated with cancer mortality in Brazilian adults: scoping review. / Indicadores de desigualdades sociais associados à mortalidade por neoplasias nos adultos brasileiros: revisão de escopo.

The objective of this study was to identify indicators of social inequalities associated with mortality from neoplasms in the Brazilian adult population. A scoping review method was used, establishing the guiding question: What is the effect of social inequalities on mortality from neoplasms in the Brazilian adult population? A total of 567 papers were identified, 22 of which were considered eligible. A variety of indicators were identified, such as the Human Development Index and the Gini Index, which primarily assessed differences in income, schooling, human development and vulnerability. A single pattern of association between the indicators and the different neoplasms was not established, nor was a single indicator capable of explaining the effect of social inequality at all levels of territorial area and by deaths from all types of neoplasms identified. It is known that mortality is influenced by social inequalities and that the study of indicators provides an opportunity to define which best explains deaths. This review highlights important gaps regarding the use of non-modifiable social indicators, analysis of small geographical areas, and limited use of multidimensional indicators.

O objetivo deste estudo foi identificar indicadores de desigualdades sociais associados à mortalidade por neoplasias na população adulta brasileira. Utilizou-se como método a revisão de escopo, estabelecendo-se a pergunta norteadora: qual o efeito das desigualdades sociais na mortalidade por neoplasias na população adulta brasileira? Foram identificados 567 trabalhos, sendo 22 considerados elegíveis. Identificou-se uma diversidade de indicadores, como o Índice de Desenvolvimento Humano e o Índice de Gini, entre outros, que avaliaram primordialmente diferenças de renda, escolarização, desenvolvimento humano e vulnerabilidade. Não foi estabelecido um único padrão de associação entre os indicadores e as diferentes neoplasias, assim como não se identificou um indicador único capaz de explicar o efeito da desigualdade social em todos os níveis de área e por óbitos por todos os tipos de neoplasias, mas identificou-se que a mortalidade é influenciada pelas desigualdades sociais e que o estudo dos indicadores proporciona definir qual melhor explica os óbitos. Essa revisão destaca importantes lacunas referentes ao uso de indicadores sociais não modificáveis, à análise de pequenas áreas e ao uso limitado de indicadores multidimensionais.

Toward the Production of Hydroxyapatite/Poly(Ether-Ether-Ketone) (PEEK) Biocomposites: Exploring the Physicochemical, Mechanical, Cytotoxic and Antimicrobial Properties.

The development of hydroxyapatite (HAp) and polyether ether ketone (PEEK) biocomposites has been extensively studied for bone repair applications due to the synergistic properties of the involved materials. In this study, we aimed to develop HAp/PEEK biocomposites using high-energy ball milling, with HAp concentrations (20%, 40%, and 60% w/v) in PEEK, to evaluate their physicochemical, mechanical, cytotoxicity, and antimicrobial properties for potential applications in Tissue Engineering (TE). The biocomposites were characterized by structure, morphology, apparent porosity, diametral compression strength, cytotoxicity, and antimicrobial activity. The study results demonstrated that the HAp/PEEK biocomposites were successfully synthesized. The C2 biocomposite, containing 40% HAp, stood out due to the optimal distribution of HAp particles in the PEEK matrix, resulting in higher compression strength (246 MPa) and a homogeneous microstructure. It exhibited antimicrobial activity against Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli, with no cytotoxicity observed. These properties make the C2 biocomposite promising for regenerative medicine applications, combining mechanical strength, bioactivity, and biocompatibility.

[Vulnerability of adolescent students to STD / HIV in Imperatriz - Maranhao]. / Vulnerabilidade de adolescentes escolares as DST/HIV, em Imperatriz-Maranhão.

The aim of this study was to investigate the vulnerability of adolescent students related to sexually transmitted diseases (STD) and the human immunodeficiency virus (HIV), identifying the main risk behaviors and prevention. This quantitative, cross-sectional study was performed in three public schools in Imperatriz--Maranhão, with 295 adolescents, using a structured questionnaire. The results show that: most young people (86.3%) who used a condom the last time they had intercourse, usually keep this practice, 82.8% of adolescents who understand the concept of HIV protect themselves against these infections and believe the main form of contamination is through sex, infected blood or through the placental barrier. We conclude that most teenager participants showed coherent knowledge about sexual practices and risk behaviors that make them vulnerable to STD/HIK presenting a positive aspect for the prevention of these diseases.

Leprosy prevalence spatial distribution and trend in a health region in Northeast Brazil, 2008-2017: an ecological study.

MAIN RESULTS: A total of 4,029 leprosy cases were notified. Mean prevalence varied between 2.0 and 11.5 cases/10,000 inhab. Spatial distribution of the cases was heterogeneous and there was a falling prevalence trend over the years studied. IMPLICATIONS FOR SERVICES: These findings point to the need to strengthen active tracing strategies and expand health actions and services targeting leprosy, with the aim of increasing detection and early treatment of cases. PERSPECTIVES: It is important to carry out epidemiological investigations on the spatial distribution and prevalence of leprosy in other health regions in the state, in order to identify other areas with greater vulnerability to leprosy. OBJECTIVE: to analyse the spatial distribution and trend of leprosy in municipalities of a health region in a Northeast Brazilian state. METHODS: this was an ecological time-series study based on compulsory notification of leprosy cases by the municipalities covered by the Imperatriz-MA Regional Health Management Unit, between 2008 and 2017; prevalence and mean prevalence for the period were calculated; spatial analysis of the area was carried out and maps were generated using ArcGis 10.5. Prais-Winsten regression was used for trend analysis. RESULT: 4,029 cases of the disease were identified, and average prevalence ranged from 2.0 to 11.5 cases/10,000 inhabitants-year. The overall trend was downward. Governador Edson Lobão had the highest prevalence, 11.5 cases/10,000 inhabitants, and Lajeado Novo had the lowest prevalence, 2.0 cases/10,000 inhabitants. CONCLUSION: spatial distribution of leprosy cases was heterogeneous in the municipalities studied and prevalence had a falling trend.

[Cross-cultural adaptation and evidence of psychometric validity of the Family Health Scale for Brazilian Portuguese]. / Adaptação transcultural e evidências de validade psicométricas da Family Health Scale para o português brasileiro.

This study aimed to translate and cross-culturally adapt the Family Health Scale into Brazilian Portuguese and analyze evidence of its psychometric validity. The 32 items on family health were cross-culturally adapted, using the content validity index to calculate semantic, idiomatic, cultural, and conceptual characteristics of the scale and its items. A pre-test to identify evidence of validity was applied to 40 families. At another time, the instrument was applied to 354 families in a Brazilian northeastern city. The index of agreement between the raters ranged from 0.84 for the scale items to 0.98 for the total scale, according to Kendall's coefficient. According to Cronbach's alpha, evidence of psychometric validity is adequate. Most families had a moderate degree of health, according to the scale. Therefore, the Brazilian version of the Family Health Scale showed conceptual, semantic, cultural, and operational equivalence with the original items, along with satisfactory psychometric properties for use among the Brazilian population with effectiveness and safety.

Os objetivos deste estudo foram realizar a tradução e adaptação transcultural da Family Health Scale (Escala de Saúde Familiar) para a língua portuguesa brasileira e analisar evidências de validade psicométricas dessa escala. Os 32 itens sobre a saúde familiar foram adaptados transculturalmente. Para a mensuração das evidências de validade do conteúdo, utilizou-se o cálculo do índice de validade de conteúdo das características semântica, idiomática, cultural e conceitual de cada item e da escala. Um pré-teste para identificação de evidência de validade foi realizado com 40 famílias. Em outro momento, a aplicação do instrumento foi executada com 354 famílias, em uma cidade no Nordeste do Brasil. O índice de concordância entre os juízes variou de 0,84, para os itens da escala, a 0,98, para a escala total, conforme o coeficiente de Kendall. As evidências de validade psicométricas mostram-se adequadas, conforme alfa de Cronbach. A maior parte das famílias teve um grau de saúde moderado, conforme aplicação da escala. Assim, a Family Health Scale, versão brasileira, apresentou equivalência conceitual, semântica, cultural e operacional em relação aos itens originais e propriedades psicométricas satisfatórias para a aplicação direcionada à população brasileira, atestando eficácia e segurança de sua utilização.

El índice de acuerdo entre los jueces osciló entre 0,84 para los ítems de la escala y 0,98 para la escala total de acuerdo con el coeficiente de Kendall. La evidencia de validez psicométrica es adecuada conforme el alfa de Cronbach. La mayoría de las familias tenían un grado de salud moderado de acuerdo con la aplicación de la escala. Por lo tanto, la Family Health Scale, versión brasileña, presentó equivalencia conceptual, semántica, cultural y operativa con relación a los ítems originales, y propiedades psicométricas satisfactorias para la aplicación en la población brasileña, lo que da fe de la eficacia y seguridad de su uso.

Individual and mutual effects of diabetes, hypertension, and obesity on acute respiratory distress syndrome mortality rates in clinical patients: a multicentre study.

Patients with comorbidities are more vulnerable to severe clinical cases of acute respiratory distress syndrome (ARDS) and COVID-19 require complex health care. To analyse the association between the individual and combined effects of diabetes, hypertension, and obesity on ARDS mortality rates among patients receiving clinical care. A multicentre study encompassing retrospective data analysis and conducted with 21,121 patients from 6,723 health services across Brazil, during the 2020-2022 time period. The sample group consisted of clinical patients of both sexes and different age groups who received clinical care and showed at least one comorbidity. The data collected were analysed using binary logistic regressions and the Chi-square test. The overall mortality rate was 38.7%, with a higher predominance among males (p < 0.001), mixed-race individuals (p < 0.001), and older adults (p < 0.001). The main comorbidity variables associated with and leading to death from ARDS were arterial hypertension (p < 0.001), diabetes mellitus (p < 0.001), diabetes mellitus and arterial hypertension (p < 0.001), cardiovascular diseases (p < 0.001) and obesity (p < 0.001). Both the patients who progressed to recovery (48.4%) and to death (20.5%) presented only one comorbidity (χ2 (1,749) = 8, p < 0.001), respectively. The isolated comorbidities with the greatest impact on death outcomes were diabetes (95% CI 2.48-3.05, p < 0.001), followed by obesity (95% CI 1.85-2.41, p < 0.001) and hypertension (95% CI 1.05-1.22, p < 0.001), even after adjusting for sex and number of simultaneous comorbidities. Diabetes and obesity, as isolated conditions, had a greater influence on the number of deaths of clinical patients with ARDS compared to those with mutual diagnosis of diabetes, hypertension and obesity.

Factors associated with deaths from COVID-19 in a region of northeastern Brazil.

INTRODUCTION: There is a need to improve knowledge and understanding of the factors associated with mortality from COVID-19 so that managers and decision-makers can implement strategies to mitigate and control the severe forms of the disease. This study aimed to determine the factors associated with deaths from COVID-19 in the state of Maranhão, in northeastern Brazil. METHODOLOGY: This is a cross-sectional and analytical study with patients with a confirmed diagnosis of COVID-19 who died from March 2020 to January 2022. Simple and multiple logistic regression models were used to assess the association between clinical-epidemiological characteristics and death. The odds ratios were expressed using a 95% confidence interval and a 5% significance level. RESULTS: A total of 386,567 cases of COVID-19 were registered in the period, of which 10,986 died. Risk factors associated with deaths from COVID-19 were male sex, age over 30 years, positive reverse transcriptase-polymerase chain reaction (RT-PCR) result, positive CT scan, and having one or more associated comorbidities. The three comorbidities linked to the highest propensity to die were diabetes mellitus, neurological disease, and obesity. CONCLUSIONS: The study findings support the implementation of strategic actions by health care and surveillance professionals and managers towards reducing the incidence of the risk factors for mortality by COVID-19 in Maranhão.

Spatiotemporal risk assessment and COVID-19 trend estimation in a federative unit in northeastern Brazil.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has spread worldwide, causing a high burden of morbidity and mortality, and has affected the various health service systems in the world, demanding disease monitoring and control strategies. The objective of this study was to identify risk areas using spatiotemporal models and determine the COVID-19 time trend in a federative unit of northeastern Brazil. METHODS: An ecological study using spatial analysis techniques and time series was carried out in the state of Maranhão, Brazil. All new cases of COVID-19 registered in the state from March 2020 to August 2021 were included. Incidence rates were calculated and spatially distributed by area, while the spatiotemporal risk territories were identified using scan statistics. The COVID-19 time trend was determined using Prais-Winsten regressions. RESULTS: Four spatiotemporal clusters with high relative risks for the disease were identified in seven health regions located in the southwest/northwest, north and east of Maranhão. The COVID-19 time trend was stable during the analysed period, with higher rates in the regions of Santa Inês in the first and second waves and Balsas in the second wave. CONCLUSIONS: The heterogeneously distributed spatiotemporal risk areas and the stable COVID-19 time trend can assist in the management of health systems and services, facilitating the planning and implementation of actions toward the mitigation, surveillance and control of the disease.

Factors associated with multibacillary leprosy in a region of northeastern Brazil.

INTRODUCTION: The analysis of factors associated with multibacillary leprosy is important for the development of strategies to mitigate the disease, which persists as a public health problem in Brazil and the world. The objective of this study was to verify the associations between sociodemographic and clinical-epidemiological variables and multibacillary leprosy in the state of northeastern Brazil. METHODOLOGY: This is a cross-sectional, analytical, and retrospective study, with a quantitative approach, carried out in 16 municipalities in the southwest of Maranhão State, northeastern Brazil. All cases of leprosy reported between January 2008 and December 2017 were considered. Sociodemographic and clinical-epidemiological variables were analyzed using descriptive statistics. The identification of the risk factors associated with multibacillary leprosy was conducted using Poisson regression models. The prevalence ratios and respective 95% confidence intervals were estimated using regression coefficients at a 5% significance level. RESULTS: A total of 3,903 leprosy cases were analyzed. Individuals older than 15 years, males, with less than 8 years of education, with level I, II, or "not evaluated" disability, and with type 1 or 2 or both reactional states were more likely to have multibacillary leprosy. Therefore, these characteristics may be considered risk factors. No protective factors were identified. CONCLUSIONS: The investigation revealed important associations between risk factors and multibacillary leprosy. The findings can be considered during the creation of strategies to control and combat the disease.
