Background: Disability insurance represents a significant economic burden within Brazil's social security system, yet long-term cost trends across disease groups remain understudied, hindering informed prevention and management strategies. Hospital costs, which account for approximately 40% of direct healthcare expenses, were selected as a comparative reference to contextualize the economic burden of disability insurance.

Objective: This study analyzes long-term cost trends of newly granted disability insurance by disease groups in Brazil, comparing them to public health system hospitalization expenses.

Post-graduation program in Ecology and Biodiversity Conservation, Federal University of Mato Grosso (UFMT), Mato Grosso, MT 78060-900, Brazil; Post-graduation program in Ecology. Department of Ecology and Zoology, Laboratory of Freshwater Biodiversity, Federal University of Santa Catarina (UFSC), Florianópolis, SC 88040-900, Brazil.

The frequency and intensity of wildfires have been increasing in many parts of the world, which may result in biodiversity loss. Wildfires can devastate plant communities, generating toxic ash that pollutes watercourses through runoff. However, our understanding of the effects of ash exposure on aquatic biodiversity is still limited.

Objective: To analyze the effects of a physical therapy intervention on the muscle strength and power of the knee flexors and extensors and functional balance in older adults with Parkinson's disease (PD), according to its clinical severity.

Methods: Forty older adults diagnosed with PD were evaluated before and after 48-week of a basic exercise program (two 20-min sessions a week) to improve functional balance and quadriceps strength. The variables analyzed were: motor aspects of PD, assessed using the Unified Parkinson's Disease Rating Scale (UPDRS); functional mobility; peak torque (PT) and mean power (MP) at the knee flexors and extensors, evaluated using an isokinetic dynamometer (CYBEX®) on both legs at 60°/s (PT) and 240°/s (P); Timed Up and Go (TUG) test; and Tinetti Index.

The aim was to compare the outcomes acquired from the OSA-Vet device with conventional quantitative and qualitative tear tests and between groups within each test, in brachycephalic dogs both healthy and those diagnosed with keratoconjunctivitis sicca. The dogs were divided into four groups: healthy dogs (HD), with mild KCS (MIKCS); moderate KCS (MOKCS); severe KCS (SKCS). All patients underwent ocular surface diagnostic examination in the following order, with a 10-minute interval between tests: non-invasive tear film breakup time (TBUTNI - OSA-Vet), tear meniscus height (TMH-OSA-Vet), meniscometry (I-Tear test), Schirmer Tear Test-1 (STT-1), and tear film breakup time (TBUT).

Members of the phospholipase D (PLD) superfamily found in Loxosceles spider venoms are potent toxins with inflammatory and necrotizing activities. They degrade phospholipids in cell membranes, generating bioactive molecules that activate skin cells. These skin cells, in turn, activate leukocytes involved in dermonecrosis, characterized by aseptic coagulative necrosis.

A novel electrochemical immunosensor for the determination of tuberculosis diagnosis exploiting graphene-affinity peptide.

Talanta

February 2025

Laboratory of Electrochemical Sensors (LabSensE), Department of Chemistry, Federal University of Paraná (UFPR), CP 19032, CEP 81531-980, Curitiba, PR, Brazil. Electronic address:

Conventional methods for diagnosing tuberculosis (TB), a significant global health challenge, often have drawbacks like time-consuming procedures, limited sensitivity, and the need for complex, expensive infrastructure. Hence, the development of electrochemical immunosensors has emerged as a promising strategy for TB detection due to their simplicity, speed, sensitivity, portability, and cost-effectiveness. In this study, we developed a rapid, simple, and low-cost immunosensor using a lab-made screen-printed electrode (SPE) based on the peptide TB 68-G as a recognition site.

Article Synopsis
  • Infectious diseases, like COVID-19, spread quickly in a globalized world, making it hard to pinpoint vulnerable populations due to intertwined individual, social, economic, and cultural factors.
  • This study aimed to identify factors that make people more susceptible to infections and severe outcomes by reviewing 45 articles published from 2019 to 2023 and categorizing vulnerabilities into individual, social, and programmatic dimensions.
  • The findings show that social vulnerabilities (like race, homelessness, and socioeconomic status) worsen individual health issues (like cancer and obesity), creating a cycle that highlights the need for public policies to address these vulnerabilities in health strategies for future pandemics.

Long-Term Nose Evaluation After Treatment of Bilateral Cleft Lip Using the Spina Technique.

J Craniofac Surg

October 2024

Federal University of Paraná (UFPR), Federal University of Paraná (UFPR), Assistance Center for Cleft Lip and Palate (CAIF), Hospital do Trabalhador, SESA PR, Curitiba, Brazil.

Introduction: Bilateral cleft lip (BCL) repair is a challenge due to anatomic and functional distortions, worse than unilateral cleft. With regard to the nose, BCL can result in certain characteristics, such as a short columella, a flattened and widened tip, and horizontally oriented nostrils. Lip and nose treatment is advocated by some surgeons to achieve a better outcome.
