Article Synopsis
  • Despite improvements in reducing maternal mortality worldwide, significant challenges remain, particularly in low- and middle-income countries.
  • Effective strategies to lower maternal mortality need a combination of health policy implementation and social development.
  • Primary care is crucial for recognizing risk factors and early signs of maternal health issues, while antenatal care addresses various conditions that can improve maternal outcomes.

The objective of the study was to compare measurements of length, thickness, and cross-section area (CSA) of the patellar tendon (PT) among cyclists, runners, triathletes, and physically active individuals (control group). Forty healthy individuals (10 cyclists, 10 runners, 10 triathletes, and 10 physically active individuals) aged between 18 and 45 years (30.3 ± 8.

The objective of this study was to evaluate the intra- and inter-rater reliability and agreement between conditions with and without a special device (SD) in the evaluation of the patellar tendon (PT) cross-sectional area (CSA). Forty trained adult volunteers participated in the study. With the knee positioned at 90°, the ultrasound probe was placed in the transverse plane at 25, 50, and 75% of the PT length.

The addition of manual pressure on the electrode during neuromuscular electrical stimulation (NMES) has been used to reduce current intensity and perceived discomfort. In this study we aimed to test i) whether this approach affect the reliability of commonly made torque output measurements and ii) whether subcutaneous-fat thickness influence the efficacy of this approach in reducing current intensity and perceived discomfort. Twenty-one men (24 ± 3.

Article Synopsis
  • - The study investigated the effectiveness of infrared thermography (IRT) for detecting subclinical mastitis in dairy cows within compost barn systems in Brazil's semiarid climate, involving evaluations of 28 cows over a week.
  • - Thermal images were analyzed for temperature readings in different udder regions, and these were correlated with somatic cell counts (SCC) to identify infections, achieving strong predictive correlations.
  • - The findings indicated that IRT is a promising and practical tool for mastitis detection, particularly in the front quarters of the udder, though further research is necessary to enhance its application in routine farm management.

As consequence of the various genomic sequencing projects, an increasing volume of biological sequence data is being produced. Although machine learning algorithms have been successfully applied to a large number of genomic sequence-related problems, the results are largely affected by the type and number of features extracted. This effect has motivated new algorithms and pipeline proposals, mainly involving feature extraction problems, in which extracting significant discriminatory information from a biological set is challenging.

Brazil is the second nation in absolute number of new cases of leprosy in the world. The country presents many regions highly endemic to the disease, as is the case of the Goiás. The present study aims to analyze the temporal trends of leprosy indicators in Goiás between 2006 and 2015.

The aim of this study was to evaluate the expression of human leukocyte antigen G (HLA-G) in leprosy. Biopsy and serum samples were collected from 18 patients presenting with leprosy and from healthy controls. Samples were analyzed using immunohistochemistry and ELISA techniques.

  • Vitamin D levels (serum 25[OH]D3) were measured in 49 adolescent dancers to explore the relationship between Vitamin D, muscle function, and injury incidence.
  • Results showed that dancers with normal Vitamin D levels experienced less muscle fatigue compared to those with insufficient levels, although other muscle function metrics were similar across both groups.
  • Over half of the dancers reported injuries, with sprains and tendinopathies being the most common types, and injured participants demonstrated lower muscle strength at 60°/s peak torque.

Human epidermal growth factor receptor-2 (HER2) is an important biomarker in the diagnosis and prognosis of breast cancer. This work aimed to develop an aptasensor to detect HER2 in human serum. HER2 aptamer was immobilized by electrostatic adsorption on the surface of a homemade screen-printed electrode modified with poly-L-lysine.

The scope of this study is to analyze the representational content and structure of the family from the viewpoint of co-resident elderly people. This is a qualitative, descriptive and exploratory study with the theoretical contribution of Social Representation Theory, from the structural perspective, conducted with 169 elderly people registered in the catchment area of two Family Health Units. The Technique of Free Evocations was used for production of data using the keyword family, and the analysis performed using EVOC software.

Despite the dramatic reduction in the number of leprosy cases worldwide in the 1990s, transmission of the causative agent, Mycobacterium leprae, is still occurring, and new cases continue to appear. New strategies are required in the pursuit of leprosy elimination. The cross-application of vaccines in development for tuberculosis may lead to tools applicable to elimination of leprosy.

The diagnosis of leprosy continues to be based on clinical symptoms and early diagnosis and treatment are critical to preventing disability and transmission. Sensitive and specific laboratory tests are not available for diagnosing leprosy. Despite the limited applicability of anti-phenolic glycolipid-I (PGL-I) serology for diagnosis, it has been suggested as an additional tool to classify leprosy patients (LPs) for treatment purposes.

Despite the advances toward the elimination of leprosy through widespread provision of multi-drug therapy to registered patients over the last 2 decades, new case detection rates have stabilized and leprosy remains endemic in a number of localized regions. A vaccine could overcome the inherent limitations of the drug treatment program by providing protection in individuals who are not already harboring the Mycobacterium leprae bacilli at the time of administration and effectively interrupt the transmission cycle over a wider timespan. In this report we present data validating the production of 73f, a chimeric fusion protein incorporating the M.

Article Synopsis
  • In leprosy, type 1 (T1R) and type 2 reactions (T2R) lead to significant nerve damage and disabilities, with a focus on the genetic role of interleukin 6 (IL-6).
  • A study involving 409 leprosy patients in Brazil found specific IL-6 gene variations linked to T2R, particularly single-nucleotide polymorphisms (SNPs) rs2069832, rs2069840, rs2069845, and rs1800795, suggesting genetic predisposition influences reaction severity.
  • No significant genetic link was established for T1R, highlighting the potential for using genetic factors to improve prevention strategies for leprosy-related complications.

Background: Leprosy is a chronic infectious disease caused by Mycobacterium leprae that can manifest a wide variety of immunological and clinical outcomes ranging from potent humoral responses among borderline lepromatous (BL) and lepromatous (LL) patients to strong cellular responses among tuberculoid (TT) and borderline tuberculoid (BT) patients. Until recently, relatively little has been known about the immune responses to individual proteins of M. leprae recognized during leprosy.

The identification of human T-cell antigens of Mycobacterium leprae could improve treatment and help to disrupt the transmission of leprosy by directing diagnosis and vaccine programs. This study screened a panel of M. leprae recombinant proteins for T-cell recall responses, measured by gamma interferon (IFN-gamma) production, among leprosy patients.
