Climate Change Scenarios and Water Implications at the Epitácio Pessoa Dam – Paraíba Yuri Batista Oliveira Gomes, Ângela Maria Cavalcanti Ramalho, Ricardo Alves de Olinda Revista De Geociencias do Nordeste, 2025 Este artigo tem como objetivo analisar os efeitos das mudanças climáticas nos recursos hídricos da barragem Epitácio Pessoa, localizada no semiárido paraibano. O estudo se concentra nas alterações nos ciclos hidrológicos, no aumento de eventos extremos e nas mudanças nos padrões de precipitação, principalmente devido a períodos prolongados de seca. A metodologia incluiu, além da revisão de literatura nacional e estrangeira, a análise de gráficos de séries temporais, dividida em dois recortes temporais: o primeiro de trinta anos (1993-2023), para dados de séries temporais, e o segundo de onze anos (2012-2023), para dados de sazonalidade, previsão, tendência e séries estacionárias que foram extraídas de bases de dados oficiais da AESA. Foram aplicados, ainda, os modelos estatísticos de ARIMA e SARIMA e testes Dickey-Fuller, para avaliar a estacionaridade, e Mann-Kendall, para identificar tendências. O presente estudo destaca a vulnerabilidade hídrica e as implicações nos sistemas hídricos nas regiões semiáridas, comprometendo o cenário climático futuro; nesse sentido, os resultados mostram variações climáticas significativas, as quais afetam a disponibilidade e a qualidade da água, a evaporação e a sazonalidade, aspectos que implicam, diretamente, no abastecimento d`água a longo prazo.
Food and nutrition actions and continuing education in Primary Healthcare: a cross-sectional study Paraíba, 2021 Micaela de Sousa Menezes, Carla Campos Muniz Medeiros, Danielle Franklin de Carvalho, Ricardo Alves de Olinda, Mônica Oliveira da Silva Simões Epidemiologia E Servicos De Saude, 2025 Objectives Describe the actions to promote adequate and healthy eating conducted in Primary Care, in addition to presenting the training provided to healthcare professionals when obesity care is offered and its association with the implementation of lines of care and food and nutritional surveillance in municipalities in the state of Paraíba, Brazil. Methods This was a cross-sectional study carried out with health professionals from January to June 2021, in municipalities in Paraíba. Descriptive analysis was performed and, to test the associations, Pearson’s chi-square test and Fisher’s exact test were used, as necessary. Results The Community actions were the most frequent, adopted by teams in 56.1% of cases, followed by group actions that occurred with a frequency of 55.0%. The implementation of the line of care was greater in municipalities with less than 30 thousand inhabitants that carried out permanent education (p-value<0.001). The implementation of food and nutritional surveillance was higher in the total sample in municipalities with 30,000 to 150,000 inhabitants and with less than 30,000 inhabitants (p-value<0.001) who carried out permanent education actions. Conclusion Community and group actions were adopted in Primary Care in Paraíba. Continuing education showed a positive association with the implementation of lines of care and nutritional surveillance, especially in smaller municipalities. These results highlighted the importance of evaluating, monitoring and expanding continuing education initiatives in Paraíba to strengthen food and nutrition actions..
Um estudo epidemiológico de tuberculose em populações vulneráveis no município do Sudeste Mato-Grossense durante a pandemia de COVID-19 Rafaela de Lima Pereira Sapiecinske, Raíza Martha Lopes dos Santos Vilela, Maraísa Delmut Borges, Letícia Silveira Goulart, Ricardo Alves de Olinda, et al. Mundo Da Saude, 2025 A tuberculose é uma doença infectocontagiosa, de determinação social e considerada um grave problema de saúde pública. Este estudo objetiva analisar os casos de tuberculose em populações vulneráveis durante a pandemia COVID-19 em Rondonópolis, Mato Grosso. Estudo epidemiológico, analítico e retrospectivo, com dados secundários de tuberculose da Vigilância Epidemiológica notificados entre março de 2020 a março de 2023. As populações vulneráveis foram consideradas casos privados de liberdade, em situação de rua e beneficiário de programa de transferência de renda do governo. Foram utilizados modelos de regressão logística para avaliar a relação entre população vulnerável e o insucesso no desfecho dos casos. Dos 315 casos notificados de tuberculose na população geral, 22,50% são população vulnerável. Estar privado de liberdade e possuir a forma extrapulmonar mostraram-se ser fatores protetores do sucesso nos desfechos dos casos (RCajustada= 0,16; IC95%= 0,03-0,75) e (RCajustada= 0,24; IC95%= 0,07-0,86), enquanto ter agravo AIDS associado e fazer uso de drogas ilícitas mostraram ser fatores de risco ao insucesso (RCajustada= 2,4; IC95%= 1,85-6,78) e (RCajustada= 3,65; IC95%= 1,06-12,53). O desfecho dos casos de tuberculose se diferencia entre as populações do estudo, fazendo-se necessário a implantação de estratégias de promoção de saúde específicas.
Um estudo epidemiológico de tuberculose em populações vulneráveis no município do Sudeste Mato-Grossense durante a pandemia de COVID-19 Rafaela de Lima Pereira Sapiecinske, Raíza Martha Lopes dos Santos Vilela, Maraísa Delmut Borges, Letícia Silveira Goulart, Ricardo Alves de Olinda, et al. Mundo Da Saude, 2025 Tuberculosis is an infectious disease with social determinants and is considered a serious public health problem. This study aimed to analyze tuberculosis (TB) cases among vulnerable populations during the COVID-19 pandemic in Rondonópolis, Mato Grosso, Brazil. This is an analytical, retrospective epidemiological study using secondary data from tuberculosis cases reported to Epidemiological Surveillance between March 2020 and March 2023. Vulnerable populations were defined as individuals deprived of liberty, people experiencing homelessness, and beneficiaries of government income transfer programs. Logistic regression models were used to assess the relationship between vulnerability and unfavorable treatment outcomes. Among the 315 tuberculosis cases reported in the general population, 22.5% were classified as belonging to vulnerable groups. Being deprived of liberty and presenting the extrapulmonary form were identified as protective factors for successful outcomes (adjusted OR = 0.16; 95% CI = 0.03–0.75) and (adjusted OR = 0.24; 95% CI = 0.07–0.86), respectively, whereas HIV/AIDS co-infection and illicit drug use were found to be risk factors for unsuccessful outcomes (adjusted OR = 2.4; 95% CI = 1.85–6.78) and (adjusted OR = 3.65; 95% CI = 1.06–12.53). The outcomes of tuberculosis cases differed among the studied populations, emphasizing the need for implementing specific health promotion strategies.

Consumption of medicines for the treatment and prevention of Covid-19: an analysis in Primary Health Care territories Isabella Alcantara de Oliveira, Ricardo Alves de Olinda, Débora Aparecida da Silva Santos, Letícia Silveira Goulart Physis, 2024 Resumo O objetivo do estudo foi avaliar o uso de medicamentos associados à Covid-19 por usuários da Atenção Primária à Saúde (APS). Trata-se de um estudo transversal com coleta de dados nas unidades de Estratégia Saúde da Família do município de Rondonópolis, MT, Brasil. Os dados foram obtidos com aplicação de um formulário semiestruturado. Dentre os participantes, 36% afirmaram ter consumido fármacos para prevenção da Covid-19, como ivermectina (89,58%), vitamina D (13,88%) e azitromicina (6,94%). Residir em domicílio em que duas ou mais pessoas precisaram sair para trabalhar na pandemia foi associado ao uso de medicamentos preventivos da Covid-19 (OR: 1,7; IC95%: 1,09 - 2,60). Os resultados indicam a necessidade de realizar ações para a promoção do uso racional de medicamentos nos territórios da APS, com vistas a capacitação profissional, educação popular em saúde e combate à desinformação.
Sociodemographic Profile and Risk Factors for the Evolution of Patients with COVID-19 in ICUs in Brazil: A Cross-Sectional Study Joelma Greicy Fernandes Lira, Ricardo Alves de Olinda, Gustavo Correia Basto da Silva, Luzibênia Leal de Oliveira, Raimunda Leite de Alencar Neta, et al. Scientific World Journal, 2024 This is a cross‐sectional study, with secondary data from Brazilian hospitals in the state of Paraíba, between January 2021 and January 2022. The evolution of clinical cases configured the dependent variable (cure or death), while the predictive variables were sociodemographic data, risk factors, use of ventilatory support, and vaccination against COVID‐19. With the help of R software, the following tests were used: chi‐square, Pearson’s chi‐square, and Fisher’s exact adherence. Simple logistic regression models were constructed, and odds ratios (95% CI) were estimated using the LR test and Wald test. 7373 cases were reported, with a mean age of 58.1. Of the reported cases, 63.8% died. The most frequent sociodemographic profile included male people, of mixed race, with less than eight years of schooling. Chronic cardiovascular disease (OR 1.28; 95% CI: 1.13–1.45), diabetes (OR 1.41; 95% CI: 1.24–1.61), lung disease (OR 1.52; 95% CI: 1.11–2.09), and the use of invasive ventilatory support (OR 14.1; 95% CI: 10.56–18.59) were all associated with increased mortality. Nonvaccination was associated with a decreased risk of death (OR 0.74; 95% CI: 0.65–0.84). Male patients, nonwhite, and those with low education were more likely to have a worse clinical outcome. The risk factors studied were related to deaths, and those who did not require ventilatory support were related to cure.
