RESUMO

Introduction: Although estimate models have been proposed to determine free-roaming (both stray and semi-domiciled) dog populations, to date, no study has focused on the three major border areas of Brazil. Therefore, the present study assessed the free-roaming dog population of Foz do Iguaçu, a major far-west Brazilian city located in a three-border area (Brazil, Argentina, and Paraguay), which is considered among the top five Brazilian tourist destinations. Methods: Capture-release sampling was performed in three phases with a 6-month interval and 10-day duration of each phase, totaling 18 months, between 2018 and 2019. Results: A total of 1,273 dogs were estimated in the first [95% confidence interval (CI), 468-2,078 dogs], 904 in the second (95%CI, 452-1,355 dogs), and 1,564 in the third (95%CI, 521-2,607 dogs) capture phases in this area, suggesting a population density of 18.4 dogs/km2 (6.1-30.6 dogs/km2, 95% CI). Of all free-roaming dogs, 452/1,125 (40.2%) were stray with no confirmed ownership or household, whereas 672/1,125 (59.8%) had a known origin, among which 625/1,125 (55.6%) were semi-domiciled with ownership or a household, 36/1,125 (3.2%) were neighborhood dogs with maintainers, and 11/1,125 (1.0%) were owned by recycling material collectors and homeless individuals. The majority of the 1,125 dogs (862/1,125; 76.6%) had an ideal body condition score. The high outdoor access of owned dogs is likely caused by cultural behavior. However, because 533/1,125 (47.4%) of the free-roaming dogs presented with clinical abnormalities, irresponsible ownership may have negatively impacted dog health and welfare. Discussion: This study was the first to establish the density of free-roaming dogs, the ratio of stray and semi-domiciled dogs, and their dynamics over time in Foz do Iguaçu. The findings may serve as a warning for the high level of dog outdoor access and irresponsible guardianship, which may negatively affect animal health and welfare, leading to diseases, accidents, trauma, and animal cruelty.

RESUMO

OBJECTIVES: Arboviruses, such as dengue (DENV), zika (ZIKV), and chikungunya (CHIKV), constitute a growing urban public health threat. Focusing on Aedes aegypti mosquitoes, their primary vectors, is crucial for mitigation. While traditional immature-stage mosquito surveillance has limitations, capturing adult mosquitoes through traps yields more accurate data on disease transmission. However, deploying traps presents logistical and financial challenges, demonstrating effective temporal predictions but lacking spatial accuracy. Our goal is to identify smaller representative areas within cities to enhance the early warning system for DENV outbreaks. METHODS: We created Sentinel Geographic Units (SGUs), smaller areas of 1 km2 within each stratum, larger areas, with the aim of aligning the Trap Positivity Index (TPI) and Adult Density Index (ADI) with their respective strata. We conducted a two-step evaluation of SGUs. First, we examined the equivalence of TPI and ADI between SGUs and strata from January 2017 to July 2022. Second, we assessed the ability of SGU's TPI and ADI to predict DENV outbreaks in comparison to Foz do Iguaçu's Early-Warning System, which forecasts outbreaks up to 4 weeks ahead. Spatial and temporal analyses were carried out, including data interpolation and model selection based on Akaike information criteria (AIC). RESULTS: Entomological indicators produced in small SGUs can effectively replace larger sentinel areas to access dengue outbreaks. Based on historical data, the best predictive capability is achieved 2 weeks after infestation verification. Implementing the SGU strategy with more frequent sampling can provide more precise space-time estimates and enhance dengue control. CONCLUSIONS: The implementation of SGUs offers an efficient way to monitor mosquito populations, reducing the need for extensive resources. This approach has the potential to improve dengue transmission management and enhance the public health response in endemic cities.

RESUMO

The present investigation aimed to develop inclusion complexes (ICs) from Psidium gaudichaudianum (GAU) essential oil (EO) and its major compound ß-caryophyllene (ß-CAR), and to evaluate their herbicidal (against Lolium multiflorum and Bidens pilosa) and cytogenotoxic (on Lactuca sativa) activities. The ICs were obtained using 2-hydroxypropyl-ß-cyclodextrin (HPßCD) and they were prepared to avoid or reduce the volatility and degradation of GAU EO and ß-CAR. The ICs obtained showed a complexation efficiency of 91.5 and 83.9% for GAU EO and ß-CAR, respectively. The IC of GAU EO at a concentration of 3000 µg mL-1 displayed a significant effect against weed species B. pilosa and L. multiflorum. However, the ß-CAR IC at a concentration of 3000 µg mL-1 was effective only on L. multiflorum. In addition, the cytogenotoxic activity evaluation revealed that there was a reduction in the mitotic index and an increase in chromosomal abnormalities. The produced ICs were able to protect the EO and ß-CAR from volatility and degradation, with a high thermal stability, and they also enabled the solubilization of the EO and ß-CAR in water without the addition of an organic solvent. Therefore, it is possible to indicate the obtained products as potential candidates for commercial exploration since the ICs allow the complexed EO to exhibit a more stable chemical constitution than pure EO under storage conditions.

RESUMO

This was a household-based prospective cohort study conducted in Rio de Janeiro, in which people with laboratory-confirmed coronavirus disease 2019 (COVID-19) and their household contacts were followed from April 2020 through June 2022. Ninety-eight reinfections were identified, with 71 (72.5%) confirmed by genomic analyses and lineage definition in both infections. During the pre-Omicron period, 1 dose of any COVID-19 vaccine was associated with a reduced risk of reinfection, but during the Omicron period not even booster vaccines had this effect. Most reinfections were asymptomatic or milder in comparison with primary infections, a justification for continuing active surveillance to detect infections in vaccinated individuals. Our findings demonstrated that vaccination may not prevent infection or reinfection with severe acute respiratory syndrome coronavirus 2 (SARS CoV-2). Therefore we highlight the need to continuously update the antigenic target of SARS CoV-2 vaccines and administer booster doses to the population regularly, a strategy well established in the development of vaccines for influenza immunization programs.

RESUMO

OBJECTIVE: To relate the distance traveled from the patient's residence to the gestational trophoblastic neoplasia (GTN) reference center (RC) and the occurrence of unfavorable clinical outcomes, as well as to estimate the possible association between this distance and the risk of metastatic disease at presentation, the need for multiagent chemotherapy to achieve remission and loss to follow-up before remission. STUDY DESIGN: Retrospective historical cohort study of patients with GTN followed at 8 Brazilian GTN-RC, from January 1st, 2000 - December 31st, 2017. RESULTS: Evaluating 1055 cases of GTN, and using a receiver operating characteristic curve, we found a distance of 56 km (km) from the residence to the GTN-RC (sensitivity = 0.57, specificity = 0.61) best predicted the occurrence of at least one of the following outcomes: occurrence of metastatic disease, need for multiagent chemotherapy to achieve remission, or loss to follow-up during chemotherapy. Multivariate logistic regression adjusted by age, ethnicity, marital status and the reference center location showed that when the distance between residence and GTN-RC was ≥56 km, there was an increase in the occurrence of metastatic disease (relative risk - RR:3.27; 95%CI:2.20-4.85), need for multiagent chemotherapy (RR:1.36; 95%CI:1.05-1.76), loss to follow-up during chemotherapy (RR:4.52; 95CI:1.93-10.63), occurrence of chemoresistance (RR:4.61; 95%CI:3.07-6.93), relapse (RR:10.27; 95%CI:3.08-34.28) and death due to GTN (RR:3.62; 95%CI:1.51-8.67). CONCLUSIONS: The distance between the patient's residence and the GTN-RC is a risk factor for unfavorable outcomes, including death from this disease. It is crucial to guarantee these patients get prompt access to the GTN-RC and receive follow-up support.

RESUMO

The rapid spread of the SARS-CoV-2 Variant of Concern (VOC) Gamma in Amazonas during early 2021 fueled a second large COVID-19 epidemic wave and raised concern about the potential role of reinfections. Very few cases of reinfection associated with the VOC Gamma have been reported to date, and their potential impact on clinical, immunological, and virological parameters remains largely unexplored. Here we describe 25 cases of SARS-CoV-2 reinfection in Brazil. SARS-CoV-2 genomic analysis confirmed that individuals were primo-infected with distinct viral lineages between March and December 2020 (B.1.1, B.1.1.28, B.1.1.33, B.1.195, and P.2) and reinfected with the VOC Gamma between 3 to 12 months after primo-infection. We found a similar mean cycle threshold (Ct) value and limited intra-host viral diversity in both primo-infection and reinfection samples. Sera of 14 patients tested 10-75 days after reinfection displayed detectable neutralizing antibodies (NAb) titers against SARS-CoV-2 variants that circulated before (B.1.*), during (Gamma), and after (Delta and Omicron) the second epidemic wave in Brazil. All individuals had milder or no symptoms after reinfection, and none required hospitalization. These findings demonstrate that individuals reinfected with the VOC Gamma may display relatively high RNA viral loads at the upper respiratory tract after reinfection, thus contributing to onward viral transmissions. Despite this, our study points to a low overall risk of severe Gamma reinfections, supporting that the abrupt increase in hospital admissions and deaths observed in Amazonas and other Brazilian states during the Gamma wave was mostly driven by primary infections. Our findings also indicate that most individuals analyzed developed a high anti-SARS-CoV-2 NAb response after reinfection that may provide some protection against reinfection or disease by different SARS-CoV-2 variants.

RESUMO

METHODS: This is a longitudinal observational study with a convenience subsample from the international Back Complaints in the Elders (BACE)-Brazil. Frailty was assessed by researchers at baseline, 6 and 12 months according to the Frailty Phenotype. Pain was assessed using a Numerical Pain Scale (NPS). Disability was assessed using the Roland Morris Disability Questionnaire. RESULTS: A total of 155 older women (70.4 ± 5.4 years) participated. Follow-up for 6 and 12 months in this study was associated with a change of older women to worse frailty levels (OR = 2.83, 95% CI 1.98-4.67; p < 0.01). A significant association was observed between greater pain intensity and the transition of the older women through the frailty levels (ß = - 0.73; p < 0.01) when inserting the pain variable at baseline of the statistical model. Older women who reported greater pain intensity worsened their frailty level. The same happened when the disability variable was inserted in the model (ß = - 0.74; p < 0.01). The criteria proposed by Fried et al. were able to identify frailty throughout the follow-up and no prevalence of any item. CONCLUSIONS: In older women, relevant factors such as pain and disability are closely linked to the frailty phenomenon. Thus, the frailty syndrome must be assessed, monitored and treated in relation to the individualities of older adults, as those with back pain and greater disabilities are more susceptible to frailty.
