Background And Purpose: Work-related musculoskeletal disorders (WMSDs) are an array of conditions affecting the human locomotor system, such as muscles, tendons, nerves, bones, and joints. It is related to physiological, kinesiological and biomechanical changes which result in pain, paresthesia, inflammation, weakness, tiredness, heaviness in limbs, fatigue, reduced range of motion and/or compression of peripheral nerves. The aim of this study was to investigate the therapeutic effects of positive (massage gum) or negative pressure (vacuum therapy) combined with laser on the health of workers with back pain, investigating pain intensity, shoulder mobility, spinal flexibility, life quality, and well-being.

Background: The rapid spread and increase of chikungunya (CHIKV) and dengue (DENV) cases in Brazilian regions in 2023 has raised concerns about the impact of arboviruses on public health. Epidemiological and genomic surveillance was performed to estimate the introduction and spread of CHIKV and DENV in Brazil.

Methods: This study obtained results from the Hermes Pardini (HP), a private medical laboratory, and the Health Department of Minas Gerais state (SES-MG).

The energy landscape of multiply connected superconducting structures is ruled by fluxoid quantization due to the implied single-valuedness of the complex wave function. The transitions and interaction between these energy states, each defined by a specific phase winding number, are governed by classical and/or quantum phase slips. Understanding these events requires the ability to probe, noninvasively, the state of the ring.

Introduction: Hemophilia A is an inherited bleeding disorder caused by pathogenic variants in the factor VIII gene (F8), which leads to factor VIII (FVIII) deficiency. Immune tolerance induction (ITI) is a therapeutic approach to eradicate alloantibodies (inhibitors) against exogenous FVIII in people with inherited hemophilia A. Few studies have evaluated the role of F8 variants on ITI outcome.

Article Synopsis
  • - The study focused on the insecticidal and repellent properties of essential oils from four plants, targeting the flea Ctenocephalides felis, which affects pets and humans globally.
  • - Using Gas Chromatography, researchers analyzed the chemical composition of the oils and tested their efficacy against different flea life stages, calculating lethal concentrations for each.
  • - Results indicated that certain oils, particularly from Copaifera reticulata, showed significant insecticidal activity and residual effectiveness, making them potential alternatives to chemical pesticides.

In this paper, we investigate a scenario in which protected and unprotected services coexist in an elastic optical network under dynamic traffic. In the investigated scenario, unprotected services can reuse the reserved idle bandwidth to provide protection to the protected services. Under this scenario, we propose a new heuristic algorithm that enables such reuse as well as define and introduce a new assignment problem in elastic optical networks, named a Transmission Spectrum Assignment (T-SA) problem.

Background: Immune tolerance induction (ITI) is the treatment of choice to eradicate neutralizing anti-factor (F)VIII alloantibodies (inhibitors) in people with inherited hemophilia A. However, it is not successful in 10% to 40% of the cases. The biological mechanisms and biomarkers associated with ITI outcome are largely unknown.

Background: Prediction of inhibitor development in patients with hemophilia A (HA) remains a challenge.

Objectives: To construct a predictive model for inhibitor development in HA using a network of clinical variables and biomarkers based on the individual similarity network.

Methods: Previously untreated and minimally treated children with severe/moderately severe HA, participants of the HEMFIL Cohort Study, were followed up until reaching 75 exposure days (EDs) without inhibitor (INH-) or upon inhibitor development (INH+).

Pineapple leaves can provide competitive and high-quality fibers for textile purposes. Despite pineapple being cultivated in the Portugues islands there is still a technology gap for the extraction and treatment of Pineapple Leaf Fibers (PALF) in Europe. Since Azorean Pineapple differs significantly from other plants in the bromeliad family, the properties and characterization of its leaf fibers were explored for the first time.

The use of hydrogels helpsthe production of plants in drought-stress environments. Thus, this work evaluated using different hydrogels to minimize drought stress in soybean cultivation. The treatments employed two different hydrogels, one already commercialized and the other produced with cashew gum (Anacardium occidentale), five levels (0, 30, 60, 120, and 240 mg pot) of the hydrogels, and two levels of drought stress in sandy soil.

Several Baccharis species are popularly known in traditional medicine as "carquejas", "vassouras", "ervas-santas" and "mio-mios", and are used as anti-inflammatories, digestives, and diuretics. This study aimed to investigate the chemical compositions and cytotoxic activities of essential oils (EOs) of six Baccharis species belonging to subgenus Coridifoliae, namely B. albilanosa, B.

The inappropriate use of antimicrobials, along with environmental conditions, can lead to the emergence of resistant microorganisms. The use of phytopharmaceuticals and herbal medicines has a positive impact and represents a promising alternative. extracts have been widely reported to have antimicrobial potential; however, studies reporting their activity against resistant bacterial strains are scarce.

A model including simultaneous droplet heating and water evaporation is proposed to simulate temperature, shrinking and mass profiles of a spherical droplet subjected to convective drying, being valid for the first drying stage. Experimental data on drying skim milk and colloidal silica obtained in the literature were used for validation, but there is no restriction in the model that prevents it from being suitable for other materials. There were not significant differences observed concerning to the droplet components (dissolved or insoluble materials).

In recent decades, waves of yellow fever virus (YFV) from the Amazon Rainforest have spread and caused outbreaks in other regions of Brazil, including the Cerrado, a savannah-like biome through which YFV usually moves before arriving at the Atlantic Forest. To identify the vectors involved in the maintenance of the virus in semiarid environments, an entomological survey was conducted after confirmation of yellow fever (YF) epizootics at the peak of the dry season in the Cerrado areas of the state of Minas Gerais. In total, 917 mosquitoes from 13 taxa were collected and tested for the presence of YFV.

Alcohol is legalized and used for a variety of reasons, including socially or as self-medication for trauma in the absence of accessible and safe supports. Trauma-informed approaches can help address the root causes of alcohol use, as well as the stigma around women's alcohol use during pregnancy. However, it is unclear how these approaches are used in contexts where pregnant and/or parenting women access care.

Article Synopsis
  • The essential oil (EO) of Cannabis sativa was tested for its effectiveness against all life stages of the flea Ctenocephalides felis felis, showing significant insecticidal activity.
  • The main components of the EO were identified as γ-elemene (16.2%) and caryophyllene oxide (14.2%) through advanced chemical analysis techniques.
  • The study found that the EO achieved 100% mortality at higher concentrations, suggesting it could be developed as a flea treatment, particularly effective against flea eggs and larvae.

Introduction: While perinatal mental health concerns are common, little attention is paid to noticing or addressing these concerns. Midwives and obstetricians are uniquely positioned to universally screen their patients for mental health conditions during the perinatal period, and provide referrals for additional mental health supports if relevant. Previous studies on perinatal mental health care have focused primarily on midwifery care, excluding perinatal healthcare providers such as obstetricians.
