RESUMEN
Abstract Background: Real-world, primary data on the treatment of psoriasis are scarce, especially concerning the role of soluble biomarkers as outcome predictors. Objective: The authors evaluated the utility of Th1/Th17 serum cytokines along with clinical characteristics as predictors of drug survival in the treatment of psoriasis. Methods: The authors consecutively included participants with moderate to severe psoriasis who were followed up for 6 years. Baseline interferon-α, tumor necrosis factor-α, and inter-leukin (IL)-2, IL-4, IL-6, IL-10, and IL-17A were measured using a cytometric bead array; clinical data were assessed. The authors calculated hazard ratios (HRs) for drug survival using a Cox proportional hazards model. Results: The authors included 262 patients, most of whom used systemic immunosuppressants or biologics. In the multivariate model, poor quality of life measured by the Dermatology Life Quality Index (HR = 1.04; 95% CI 1.01-1.07; p = 0.012) and elevated baseline IL-6 (HR = 1.99; 95% CI 1.29-3.08; p = 0.002) were associated with treatment interruption. Study limitations: The main limitation of any cohort study is the presence of confounders that could not be detected in clinical evaluation. Conclusions: Poor quality of life and elevated baseline serum IL-6 level predicted treatment interruption in patients with moderate to severe psoriasis. Although IL-6 is not the most important mediator of the inflammatory pathway in the skin environment, it is an interesting biomarker candidate for predicting psoriasis treatment response.

STUDY LIMITATIONS: The main limitation of any cohort study is the presence of confounders that could not be detected in clinical evaluation. CONCLUSIONS: Poor quality of life and elevated baseline serum IL-6 level predicted treatment interruption in patients with moderate to severe psoriasis.

The article proposes a discussion on the daily life and occupations of an adult with autism. In this regard, a study that sought to understand how the daily life of an adult woman with autism is structured, from the perspective of one of the main caregivers, is presented. This was a qualitative study, a case study, conducted in Santos, São Paulo, Brazil. Through a semi-structured interview, categories such as daily activities and occupations, and the challenges faced by the individual and their family were selected and analyzed. The results emphasize the importance of creating spaces for discussion that address different ways of experiencing adulthood and the aging process with autism. Furthermore, it advocates for dialogue on active aging, participating in community activities, exercising citizenship, and accessing rights. The findings also highlight the need for the development of services that support transitions across the lifespan of people with autism spectrum conditions and encourage professionals to develop care actions aimed at the specific demands of these people and their families.
RESUMEN
Mangabeira (Hancornia speciosa) is a Brazilian tree and a socioeconomic key due to the commercialization of its food products and tree parts to treat health conditions empirically. This review gathers the main chemical, and microbiological characteristics of the mangabeira tree parts (leaves, fruits, tree bark, latex, and seeds), emphasizing its applicability in food science and focusing on its bioapplicability in health conditions. Leaves, fruits, and tree bark can be used to develop functional foods, and phytochemical products; the tree latex have great potential in the bioengineering material field; and the seeds in sustainable energy production. Leaves and fruits were the main samples bioapplied in health conditions in vitro (oxidative stress and chemopreventive effect) and in vivo (gastrointestinal and cardiovascular health, anti-inflammatory, and antidiabetic effect), whereas tree bark and latex also exhibited health effects and seeds showed low cytotoxicity. All parts of the mangabeira tree can be explored by extractivist families and industries from a sustainable point of view.
RESUMEN
Non-alcoholic fatty liver disease (NAFLD) is a metabolic disorder caused by excess consumption of hypercaloric foods. Guavira (Campomanesia sp.) pulp has broad technological applicability, yet the peel and seeds are considered industrial residue. The objective of this unprecedented study was to evaluate the effects of the flour from guavira's industrial residue (GF) consumption in rats fed with hypercaloric diet (HD). During 65 days, 50 rats were separated into a control group: 1%, 2%, 4% and 8% HD with GF complementation in the diet. The GF chemical composition, phenolic compounds, antioxidant capacity, serum biochemical parameters (glucose, cholesterol, HDL, non-HDL, triglycerides, AST, ALT, and oral glucose tolerance test), fat liver content, and hepatic histomorphology had been characterized. GF is mainly composed of fibres, with phenolic content of 7,391.09 mg AGE/100 g GF and relevant antioxidant capacity (IC50 2.22 and ORAC 155.68 µmol/TE g-1 ). Serum biochemical analysis did not differ statistically (except ALT reduction, p < .05). Fat liver content was smaller on HD2%GF (p < .0001). The control group and 1% GF showed greater diffuse microvesicular steatosis compared to the other groups when using hepatic morphological analysis (p < .05). GF consumption attenuated NAFLD caused by a hypercaloric diet, and this effect may be related to the fibre content and bioactive compounds in GF.

The prevalence of gastrointestinal disorders, such as constipation, has been increasing. Genetic factors and lifestyle are some of the etiologies of this issue, affecting the health of the population. Natural products have properties that contribute to health maintenance and health promotion, including reduction of the inflammatory process. Hancornia speciosa, popularly known as mangaba, is an abundant and native fruit in the Brazilian Cerrado, commercialized for culinary purposes and used because of its pharmacological properties. The objective of this study was to evaluate if the supplementation of different concentrations of mangaba pulp can improve intestinal motility and bowel health in Wistar rats. Forty male rats were divided into five groups. The experiment lasted 14 days and the groups were tested with water, industrialized laxative jelly made from tamarind as medication, or mangaba at 5, 10, and 15 mL/kg of body weight. Food intake, weight gain, ion balance, intestinal motility, and histopathological analysis of the small intestine, large intestine, and liver were evaluated. Supplementation of mangaba pulp at its highest concentration (15 mL/kg body weight) caused a 15% increase in the distance traveled by the charcoal meal, and a decrease in serum magnesium levels and white cells in both the small and large intestines. The results suggest that mangaba pulp presents laxative, anti-inflammatory properties and that its consumption is beneficial and should be encouraged.

The development of new antimalarial drugs is urgent to overcome the spread of resistance to the current treatment. Herein we synthesized the compound 3, a hit-tolead optimization of a thiazole based on the most promising 3-alkylpyridine marine alkaloid analog. Compound 3 was tested against Plasmodium falciparum and has shown to be more potent than its precursor (IC50 values of 1.55 and 14.7⯵M, respectively), with higher selectivity index (74.7) for noncancerous human cell line. This compound was not mutagenic and showed genotoxicity only at concentrations four-fold higher than its IC50. Compound 3 was tested in vivo against Plasmodium berghei NK65 strain and inhibited the development of parasite at 50â¯mg/kg. In silico and UV-vis approaches determined that compound 3 acts impairing hemozoin crystallization and confocal microscopy experiments corroborate these findings as the compound was capable of diminishing food vacuole acidity. The assay of uptake using human intestinal Caco-2 cell line showed that compound 3 is absorbed similarly to chloroquine, a standard antimalarial agent. Therefore, we present here compound 3 as a potent new lead antimalarial compound.
