Patient's Perception of Primary Health Care Provision With Respect to Access, Continuity and Coordination-InCept: An International Qualitative Perspective.

Health care systems are confronted with an increasing burden of (multi-)morbidity and a shortfall of healthcare providers. Coordination and continuity of care in chronic and multi-morbid patient is especially important. As qualitative patient experience data within care processes is scarce, we aim to increase the understanding of chronically ill patient's perspectives by assessing patient experiences in different health systems while treated in primary care.

Fibrinolytic enzyme from Arthrospira platensis and its effects on breast cancer cells: Exploring its potential as an innovative therapy.

Fibrinolytic enzymes are promising in treating cardiovascular diseases due to their capacity to dissolve blood clots. The fibrinolytic enzyme from Arthrospira platensis (FEAP) was purified by ion exchange chromatography to investigate its ability to activate plasminogen, as well as its thrombolytic and fibrinogenolytic potential. Subsequently, two different cytotoxic assays (MTT and NR) and hemolysis test were performed to evaluate FEAP's safety.

Influence of the addition of gum arabic and xanthan gum in the preparation of sodium alginate microcapsules coated with chitosan hydrochloride on the survival of Lacticaseibacillus rhamnosus GG.

The microencapsulation of Lactocaseibacillus rhamnosus GG in a matrix of sodium alginate, xanthan gum, gum arabic and chitosan hydrochloride is a promising strategy for protecting this probiotic during passage through the gastrointestinal tract. This study evaluated the influence on the viability of Lactocaseibacillus rhamnosus GG encapsulated with these polymers by external ionic gelation with vibratory extrusion and the microcapsules that showed the best results of capsulation efficiency, viability, size and morphology were analyzed by Fourier transform infrared spectroscopy (FTIR), thermal analysis (TGA) and exposure to environmental stress conditions and gastrointestinal simulation. The result revealed encapsulation efficiency values above 95 % for all formulations and survival rate higher than 6 log CFU/mL for most analyzed groups.

The Influence of Fluoxetine on the Sensorimotor Function of the Sciatic Nerve in Wistar Rats after Axonotmesis: An Experimental Animal Model.

Background: Fluoxetine, a serotonin reuptake inhibitor antidepressant, raises extracellular serotonin levels and promotes angiogenesis and neurogenesis. Numerous animal models have shown its beneficial effects on recovery from peripheral nerve injury.

Purpose: The primary objective of this study was to analyze the influence of fluoxetine on the sensory-motor function recovery of the sciatic nerve in Wistar rats after axonotmesis.

Lectin from microalgae: Non-toxic to human cells and effective against Leishmania.

New leishmanicidal products are needed for the treatment to be effective, since current drugs are toxic to healthy human/animal cells and have low efficacy against the parasite. Bioactive compounds from microalgae, such as lectins, can be explored as new anti-Leishmania candidates. This study aimed to evaluate the cytotoxic and anti-Leishmania action of the cell extract (CE) and lectin (CVU) from Chlorella vulgaris biomass.

Green synthesis of silver nanoparticles derived from algae and their larvicidal properties to control .

Mosquito vectors such as . are responsible for the transmission of arboviruses that have a major impact on public health. Therefore, it is necessary to search for ways to control these insects, avoiding the use of conventional chemical insecticides that are proven to be toxic to nature.

Topiramate Inhibits Capsaicin-Induced Mast Cell Degranulation and CGRP Release in Rat Dura Mater.

Background/objectives: Migraine is a disease that stands out for its high prevalence and socioeconomic costs. It involves the entire trigeminovascular system, the signaling substances, and their targets. However, the role of meningeal mast cells in migraine is still unclear.

Anorexigenic and anti-inflammatory signaling pathways of semaglutide via the microbiota-gut--brain axis in obese mice.

Our study focused on a mouse model of obesity induced by a high-fat diet (HFD). We administered Semaglutide intraperitoneally (Ozempic ®-0.05 mg/Kg-translational dose) every seven days for six weeks.

Purification and characterization of a protease produced by submerged fermentation: Ultrasound-enhanced collagenolytic protease from Streptomyces parvulus.

Proteases are a large group of enzymes in high demand due to their wide and different biotechnological applications mainly in the biomedical field. Ultrasound (US) has been used successfully in several Bioprocesses in biotechnology, such as in the upregulation of enzymatic hydrolysis (biocatalysis). The objective of this work was to purify an enzyme from Streptomyces parvulus and to characterize it through physic-chemical applications including ultrasound effect.

Occult Urinary Incontinence, Diabetes, Obesity, Prolapse Severity, and Type of Surgical Repair as Risk Factors for De Novo Stress Urinary Incontinence in Women Undergoing Surgical Repair of Pelvic Organ Prolapse: A Systematic Review and Meta-Analysis.

Purpose: The International Continence Society and the International Urogynecological Association have not yet standardized the definition of de novo stress urinary incontinence. Recent studies define the development of stress urinary incontinence as occurring after surgical repair of pelvic organ prolapse in previously continent women. The mechanisms that cause de novo stress urinary incontinence are not yet clear.

Toll-like receptors polymorphisms and COVID-19: a systematic review.

COVID-19 is a disease caused by SARS-CoV-2. It became a health problem affecting the lives of millions of people. Toll-like receptors are responsible for recognizing viral particles and activating the innate immune system.

Food Consumption According to the NOVA Food Classification and Its Relationship with Symptoms of Depression, Anxiety, and Stress in Women.

Background/objectives: Depression, anxiety, and stress are highly prevalent mental disorders worldwide, and food consumption can change in individuals with these conditions. We aimed to assess the food consumption of women with depressive symptoms and compare it to a control without symptoms.

Methods: A cross-sectional study was conducted with 96 women, aged 18-59, allocated into two groups: control = 62) or depressive symptoms ( = 34).

Melatonin and Bacterial Cellulose Regulate the Expression of Inflammatory Cytokines, VEGF, PCNA, and Collagen in Cutaneous Wound Healing in Diabetic Rats.

The poor healing of diabetic wounds is characterized by prolonged inflammation and decreased collagen deposition. Diabetic patients exhibit changes in the plasma concentrations of pro-inflammatory cytokines, and the role of specific dressings may have an impact on healing. This study aims to evaluate the effects of a combined treatment comprising a bacterial cellulose dressing and melatonin application on the regulation and expression of inflammatory cytokines, VEGF, PCNA, and collagen in the healing of cutaneous wounds of diabetic rats.

Nanostructures for Delivery of Flavonoids with Antibacterial Potential against .

Flavonoids are secondary metabolites that exhibit remarkable biological activities, including antimicrobial properties against , a pathogen responsible for several serious nosocomial infections. However, oral administration of these compounds faces considerable challenges, such as low bioavailability and chemical instability. Thus, the encapsulation of flavonoids in nanosystems emerges as a promising strategy to mitigate these limitations, offering protection against degradation; greater solubility; and, in some cases, controlled and targeted release.
