Zinc/Magnesium Ferrite Nanoparticles Functionalized with Silver for Optimized Photocatalytic Removal of Malachite Green.

Water pollution is a major environmental challenge. Due to the inefficiency of conventional wastewater treatment plants in degrading many organic complex compounds, these recalcitrant pollutants end up in rivers, lakes, oceans and other bodies of water, affecting the environment and human health. Semiconductor photocatalysis is considered an efficient complement to conventional methods, and the use of various nanomaterials for this purpose has been widely explored, with a particular focus on improving their activity under visible light. This work focuses on developing magnetic and photoactive zinc/magnesium mixed ferrites (Zn0.5Mg0.5Fe2O4) by sol-gel and solvothermal synthesis methods, which are two of the most important and efficient methods used for the synthesis of ferrite nanoparticles. The nanoparticles (NPs) synthesized by the sol-gel method exhibited an average size of 14.7 nm, while those synthesized by the solvothermal method had an average size of 17.4 nm. Both types possessed a predominantly cubic structure and demonstrated superparamagnetic behavior, reaching a magnetization saturation value of 60.2 emu g-1. Due to the high recombination rate of electrons/holes, which is an intrinsic feature of ferrites, surface functionalization with silver was carried out to enhance charge separation. The results demonstrated a strong influence of adsorption and of the deposition of silver. Several optimization steps were performed during synthesis, allowing us to create efficient catalysts, as proved by the almost full removal of the dye malachite green attaining 95.0% (at a rate constant of 0.091 min-1) and 87.6% (at a rate constant of 0.017 min-1) using NPs obtained by the sol-gel and solvothermal methods, respectively. Adsorption in the dark accounted for 89.2% of the dye removal for nanoparticles prepared by sol-gel and 82.8% for the ones obtained by the solvothermal method. These results make mixed zinc/magnesium ferrites highly promising for potential industrial application in effluent photoremediation using visible light.

Aleitamento materno e o processo de adaptação no contexto familiar: abordagem qualitativa / Breastfeeding and the adjustment process in the family context: a qualitative approach

OBJETIVO: Compreender a adaptação das mulheres ao processo de amamentação e o apoio familiar e dos serviços de saúde. MÉTODO: Estudo qualitativo fundamentado no referencial metodológico da Etnoenfermagem, conforme a Teoria de Enfermagem Transcultural de Leininger. Foi utilizado um roteiro de entrevista semiestruturada. RESULTADOS: Evidenciaram-se três categorias temáticas: "Enfrentando algo inesperado, mutável e desafiador"; "Convivendo com dúvidas, incertezas e desorientação" e "Identificando fontes de apoio para a manutenção da amamentação". CONCLUSÃO: O processo de adaptação do aleitamento materno é permeado por dúvidas, incertezas e desafios. As mulheres apoiam-se em suas experiências prévias e na cultura familiar e sofrem influência direta destas. O papel da atenção básica é essencial nesse contexto.

OBJECTIVE: To understand women's adaptation to the breastfeeding process and the support provided by family and health services. METHOD: A qualitative study based on the methodological framework of Ethnonursing, following Leininger's Transcultural Nursing Theory. A semi-structured interview guide was used. RESULTS: Three thematic categories were identified: "Facing something unexpected, changing, and challenging"; "Dealing with doubts, uncertainties, and disorientation"; and "Identifying sources of support for breastfeeding maintenance". CONCLUSION: The breastfeeding adjustment process has doubts, uncertainties, and challenges. Women rely on and are directly influenced by their past experiences and family culture. The role of primary health care is crucial in this context.

Older adults, appendicular anthropometric measurements, and poor functional performance are predictors of sarcopenia in individuals with head and neck squamous cell carcinoma.

OBJECTIVE: To identify predictors of sarcopenia (demographical, anthropometric measurements, tumor-related clinical characteristics, performance status, and serum C-reactive protein (CRP) and albumin levels in individuals with head and neck squamous cell carcinoma (HNSCC). MATERIAL AND METHODS: This cross-sectional study selected diagnosed with HNSCC (n = 125). Sarcopenia was defined as low muscle strength and low physical performance. Association between sarcopenia and anthropometric assessments (weight, height, body mass index, triceps skinfold, mid-upper arm circumference [MUAC], mid-upper arm muscle circumference, mid-upper arm fat area [UFA], mid-upper arm bone free muscle area, calf circumference, and appendicular skeletal muscle mass and index), tumor clinical characteristics (anatomical site, tumor size, and cervical metastasis), performance status scale (Eastern Cooperative Oncology Group Performance Status [ECOG-PS]), and CRP and albumin levels was analyzed using binary logistic regression models. RESULTS: The diagnosis of sarcopenia was identified in 28 (22.4%) individuals with HNSCC. Being an older adult increases the odds of association with sarcopenia in individuals with HNSCC (odds ratio [OR] = 1.05). Increments in MUAC measurement reduce the odds of association with sarcopenia (OR = 0.69), while the increase in the UFA measurement increases the odds of association with sarcopenia (OR = 1.33). Poor ECOG-PS scores increase the odds of association with sarcopenia in individuals with HNSCC (OR = 5.54). CONCLUSION: Early identification of easy-to-perform, cost-effective predictors of sarcopenia tends to favor the implementation of personalized therapeutic and supportive interventions in individuals with HNSCC.

Trends in the prevalence of obesity, overweight, and thinness among schoolchildren aged 7-14 years from southern Brazil (2002-2019).

OBJECTIVE: To analyze the obesity, overweight, and thinness trends among Brazilian schoolchildren by sex, age group, and type of school according to World Health Organization (WHO) and International Obesity Task Force (IOTF) criteria. METHODS: We conducted four surveys between 2002 and 2018/19 involving schoolchildren aged 7-14 years from a state capital in southern Brazil. Weight status was classified using both WHO and IOTF criteria. RESULTS: In the total sample, obesity prevalence based on the IOTF and the WHO criteria were 72% and 44% higher in 2018/19 compared with 2002, respectively. Over the whole period, the obesity prevalence increased among children (WHO: 10.1% vs. 14.1%; IOTF: 5.0% vs. 8.3%), and those from public schools (WHO: 10.5% vs. 16.4%; IOTF: 5.6% vs. 10.1%). There was no significant reduction in thinness prevalence over the analyzed period. CONCLUSION: Obesity prevalence remains on an upward trend in a state capital in southern Brazil, especially among children from public schools. A higher prevalence of overweight and obesity was observed using the WHO criteria compared with IOTF criteria.

The effect of oral dietary interventions on nutritional status and treatment tolerance in patients with hematologic neoplasms receiving chemotherapy: a systematic review.

CONTEXT: Adverse events from chemotherapy treatment affect food intake, nutritional status, and treatment tolerance in cancer patients. However, the effect of nutritional intervention in patients with hematologic neoplasms receiving chemotherapy remains unknown. OBJECTIVE: The aim of this systematic review was to evaluate the evidence on nutritional interventions on nutritional status, treatment tolerance, inflammatory markers, quality of life, and mortality in patients with hematologic neoplasms receiving chemotherapy. DATA SOURCES: The MEDLINE, LILACS, CINAHL, Web of Science, Embase, ICTRP, CENTRAL, and ClinicalTrials.gov databases were searched. Additional literature and the bibliographies of identified articles were also considered. DATA EXTRACTION: Randomized controlled trials in individuals with hematologic neoplasms receiving chemotherapy along with nutritional counseling and oral nutritional supplementation, and intake of supplementary food products, alone or in combination, were assessed as criteria of interest. The data were extracted independently by 2 researchers. The risk of bias was assessed through the Cochrane risk-of-bias tool (RoB 2). DATA ANALYSIS: Ten studies were included up to August 15, 2022 (updated in November of 2022). With regard to the outcomes, 4 studies assessed nutritional status and 2 studies showed a positive result of the intervention on some of the markers. Seven studies assessed certain markers of treatment tolerance and only 2 studies showed improvement in the outcome after the intervention. CONCLUSION: The studies that found positive results are quite different from each other in terms of intervention, study time, and design. More randomized controlled trials are needed to test different dietary interventions using placebo and blinding, when possible, and with reduced sample variability in individuals with hematologic neoplasms receiving chemotherapy. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration no. CRD42020196765.

Association between Sleep Timing, Being Overweight and Meal and Snack Consumption in Children and Adolescents in Southern Brazil.

Sleep timing is one of the dimensions of sleep that refers to the time of day when sleep occurs. It has been included in sleep-related research because of the potential associations between being overweight and the consumption of meals and snacks. This cross-sectional study aimed to investigate associations between sleep timing, meal and snack consumption and weight status in 1333 schoolchildren aged 7-14 years. The midpoint of sleep was used as a sleep timing measure obtained by the midpoint between bedtime and wake-up time, classified as Early, Intermediate, and Late. Schoolchildren in the Early group were less likely to be overweight (OR: 0.83, 95% CI 0.69; 0.99), and had higher odds of mid-morning snack consumption (OR: 1.95, 95% CI 1.56; 2.44) and lower probability to consume an evening snack (OR: 0.75, 95% CI 0.59; 0.94) compared with the Intermediate group. The Late group had lower odds of mid-morning snack consumption (OR: 0.67, 95% CI 0.55, 0.80) than the Intermediate group. The consumption of mid-morning and evening snacks was associated with the Early and Late midpoints of sleep. These results suggest that bedtime and wake-up time are relevant to consuming meals and snacks and may also be related to a greater probability of being overweight in children and adolescents.

Exploring the correlations between epi indicators of COVID-19 and the concentration of pharmaceutical compounds in wastewater treatment plants in Northern Portugal.

The COVID-19 pandemic caused by the SARS-CoV-2 virus led to changes in the lifestyle and human behaviour, which resulted in different consumption patterns of some classes of pharmaceuticals including curative, symptom-relieving, and psychotropic drugs. The trends in the consumption of these compounds are related to their concentrations in wastewater systems, since incompletely metabolised drugs (or their metabolites back transformed into the parental form) may be detected and quantified by analytical methods. Pharmaceuticals are highly recalcitrant compounds and conventional activated sludge processes implemented in wastewater treatment plants (WWTP) are ineffective at degrading these substances. As a results, these compounds end up in waterways or accumulate in the sludge, being a serious concern given their potential effects on ecosystems and public health. Therefore, it is crucial to evaluate the presence of pharmaceuticals in water and sludge to assist in the search for more effective processes. In this work, eight pharmaceuticals from five therapeutic classes were analysed in wastewater and sludge samples collected in two WWTP located in the Northern Portugal, during the third COVID-19 epidemic wave in Portugal. The two WWTP demonstrated a similar pattern with respect to the concentration levels in that period. However, the drugs loads reaching each WWTP were dissimilar when normalising the concentrations to the inlet flow rate. Acetaminophen (ACET) was the compound detected at highest concentrations in aqueous samples of both WWTP (98. 516 µg L - 1 in WWTP2 and 123. 506 µg L - 1in WWTP1), indicating that this drug is extensively used without the need of a prescription, known of general public knowledge as an antipyretic and analgesic agent to treat pain and fever. The concentrations determined in the sludge samples were below 1.65 µg g - 1 in both WWTP, the highest value being found for azithromycin (AZT). This result may be justified by the physico-chemical characteristics of the compound that favour its adsorption to the sludge surface through ionic interactions. It was not possible to establish a clear relationship between the incidence of COVID-19 cases in the sewer catchment and the concentration of drugs detected in the same period. However, looking at the data obtained, the high incidence of COVID-19 in January 2021 is in line with the high concentration of drugs detected in the aqueous and sludge samples but prediction of drug load from viral load data was unfeasible.

Inhibition of α-Glycosidase by Lippia dulcis Trevir. (Verbenaceae) Preparations, Quantification of Verbascoside, and Study of Its Molecular Docking.

This study aimed to quantify verbascoside (VEB), perform molecular docking studies of VEB with the α-glucosidase (GL) of Bacillus stearothermophilus, and evaluate the inhibition of the enzyme by L. dulcis preparations. The substrate concentration and presence of reduced glutathione were evaluated for their effect on the in vitro inhibition of the GL enzyme. Assays were also performed in the presence and absence of simulated gastric fluid. The antidiabetic fractions 2 and 3 were the most inhibited GL, but their activity were significantly decreased in the presence of gastric fluid. Chromatographic analyses confirmed the predominant presence of VEB in the samples. The samples had VEB concentrations between 49.9 and 243.5 mg/g. Simulation of the molecular docking of VEB were consistent with its GL-inhibitory activity. It can conclude that the crude ethanol extract and fractions show inhibitory activity against the GL enzyme.

How Brazilian Schoolchildren Identify, Classify, and Label Foods and Beverages-A Card Sorting Methodology.

This study examined how Brazilian schoolchildren identified, classified, and labeled foods and beverages. Semi-structured interviews were conducted with 133 schoolchildren aged 7 to 10 years old from a public school located in southern Brazil in 2015. A set of cards with pictures of 32 food and beverage items from the web-based Food Intake and Physical Activity of Schoolchildren tool (Web-CAAFE) were used. Participants identified each item, formed groups for them based on similarity, and assigned labels for those groups. Student's t-tests and analysis of variance (ANOVA) tests were used to verify the mean difference between the groups of items. K-means cluster analysis was applied to identify similar clusters. Schoolchildren made an average of 9.1 piles of foods and beverages that they thought were similar (±2.4) with 3.0 cards (±1.8) each. Five groups were identified: meats, snacks and pasta, sweets, milk and dairy products, and fruits and vegetables. The most frequently used nomenclature for labeling groups was taxonomic-professional (47.4%), followed by the specific food item name (16.4%), do not know/not sure (13.3%), and evaluative (health perception) (8.8%). The taxonomic-professional category could be applied to promote improvements in the identification process of food and beverage items by children in self-reported computerized dietary questionnaires.

Sodium butyrate attenuates peritoneal fibroproliferative process in mice.

NEW FINDINGS: What is the central question of this study? Peritoneal injury can result in a persistent fibroproliferative process in the abdominal cavity, causing pain and loss of function of internal organs. This study aimed to demonstrate the use of sodium butyrate (NaBu) as a potential agent to attenuate peritoneal fibrosis induced by a synthetic matrix. What is the main finding and its importance? Our findings provide the first evidence that NaBu attenuates the inflammatory, angiogenesis and fibrogenesis axes involved in the formation of peritoneal fibrovascular tissue, indicating the potential of this compound to ameliorate peritoneal fibrosis. ABSTRACT: The aim of this study was to identify the bio-efficacy of sodium butyrate (NaBu) on preventing the development of peritoneal fibrovascular tissue induced by implantation of a synthetic matrix in the abdominal cavity. Polyether-polyurethane sponge discs were implanted in the peritoneal cavity of mice, which were treated daily with oral administration of NaBu (100 mg/kg). Control animals received water (100 µl). After 7 days, the implants were removed for assessment of inflammatory, angiogenic and fibrogenic markers. Compared with control values, NaBu treatment decreased mast cell recruitment/activation, inflammatory enzyme activities, levels of pro-inflammatory cytokines, and the proteins p65 and p50 of the nuclear factor-κB pathway. Angiogenesis, as determined by haemoglobin content, vascular endothelial growth factor levels and the number of blood vessels in the implant, was reduced by the treatment. In NaBu-treated animals, the predominant collagen present in the abdominal fibrovascular tissue was thin collagen, whereas in control implants it was thick collagen. Transforming growth factor-ß1 levels were also lower in implants of treated animals. Sodium butyrate downregulated the inflammatory, angiogenesis and fibrogenesis axes of the fibroproliferative tissue induced by the intraperitoneal synthetic matrix. This compound has potential to control/regulate chronic inflammation and adverse healing processes in the abdominal cavity.

Methodological aspects and characteristics of participants in the study on the prevalence of obesity in children and adolescents in Florianópolis, Southern Brazil, 2018-2019: EPOCA study.

PURPOSE: To describe the methodological aspects and characteristics of the participants of the EPOCA survey. METHODS: The study was conducted with schoolchildren aged between seven to 14 years old from 30 schools in Florianópolis, Southern Brazil. Body mass, height, girths, and skinfold thicknesses were measured. Food consumption and physical activity from the previous day were self-reported using the validated Web-CAAFE questionnaire. Adolescents completed a specific questionnaire about physical activity, meal consumption, and weight control behaviors. Parents/guardians responded to a sociodemographic and habits questionnaire. RESULTS: A total of 1671 schoolchildren participated in the study (response rate: 27.2%). About 63% of schoolchildren were enrolled in public schools. Most studied in the morning shift (54.2%), were female (53.1%) and aged between seven and 10 years (58.1%). The prevalence of overweight was 33.7% and obesity was 11.3%. CONCLUSIONS: The data obtained will allow us to assess the trend in the prevalence of overweight and obesity and associated factors when compared to other surveys performed. Descriptions of the logistics and protocols can help in the development and improvement of similar studies. It is hoped that the results of EPOCA 2018/2019 may help in the design of obesity prevention policies and programs for this population.

Brazilian Consensus on Sleep-Focused Speech-Language-Hearing Sciences - 2023 Brazilian Sleep Association.

Introduction This consensus aimed to develop a structured document presenting the role of sleep-focused Speech-Language-Hearing (SPH) Sciences (SPHS). The recommendations were based on the expertise of specialists and on evidence in the literature, aiming to guide the coverage of this area and the consequent improvement in the quality of the professionals' approach. Methods A Delphi method was conducted with 49 SLH pathologists (SLHP), four sleep physicians, one dentist, one physical therapist, and one methodologist. Four Delphi panel rounds were conducted in Google Forms. The items were analyzed based on the panelists' percentage of agreement; consensuses were reached when ⅔ (66.6%) of valid responses were on a same on a same answer (either "agree" or "disagree"). Results Participants voted on 102 items. The mean consensus rate was 89.9% ± 10.9%. The essential topics were the importance of professional training, the SLH diagnosis, and the SLH treatment of sleep disorders. It was verified that all fields of the SLHS are related to the area of sleep; that sleep-focused SLH pathologists (SLHP) are the responsible for assessing, indicating, and conducting specific orofacial myofunctional therapy for sleep-disordered breathing alone or in combination with other treatments; that SLHP are included in interdisciplinary teams in the area of sleep in public and private services. Discussion The Brazilian consensus on sleep-focused SLHS is a landmark in this area. This consensus described the scope of action of sleep-focused SLHP and systematized recommendations being useful as a reference for the professional practice in the area of sleep.

Voice therapy with a respiratory approach in older adults: the practice of Brazilian speech-language-hearing therapists / Terapia vocal com abordagem respiratória em idosos: prática de fonoaudiólogos brasileiros

ABSTRACT Purpose: to investigate the practice of Brazilian speech-language-hearing therapists in voice therapy for older adults focused on breathing and verify possible associations between taking specific courses and having knowledge of respiratory parameters, between using incentive spirometers and respiratory devices, and between age and the use of these instruments. Methods: the sample had 156 specialists in voice, contacted via email, who answered a form in Google Forms. Specialists in voice with 3 or more years of experience were included, whereas those who did not fill out the questionnaire completely were excluded. The analysis addressed absolute and relative frequencies and associations with the chi-square test. Significance was set at 5%. Results: most participants took courses on respiratory approach. The use of facilitating sounds, vocal function exercises, and respiratory instruments stood out, with reported vocal improvements. The use of incentive spirometers was associated with respiratory devices, and age was associated with the use of respiratory instruments. Conclusion: speech-language-hearing therapists with expertise in voice provide voice therapy for dysphonic older people focusing on a respiratory approach. Professionals who use incentive spirometers also use respiratory devices. Older therapists are the ones who most use respiratory instruments and taking specific courses was not associated with knowledge on respiratory parameters.

Sleep Quality, Excessive Daytime Sleepiness, and Physical Activity Level in Health Professionals with and Without COVID-19: a Cross-Sectional Study.

Objective To compare the sleep quality, excessive daytime sleepiness, and physical activity level in health professionals infected and not infected with COVID-19. Methods Cross-sectional study based on online forms (Google Forms) filled out by health professionals who cared for COVID- 19 patients in hospitals in the Recife metropolitan area, Brazil, between October 2020 and May 2021. Anthropometric, sociodemographic, and occupational data were collected, along with the assessment of excessive daytime sleepiness (with Epworth Sleepiness Scale [ESE]), sleep quality (with Pittsburgh Sleep Quality Index [PSQI]), and physical activity level (with International Physical Activity Questionnaire [IPAQ] - short version). Results A total of 96 participants were assessed (37 with COVID-19, 59 without COVID-19). There were no differences between the groups regarding physical activity levels classified as sedentary, moderately active, or highly active (p = 0.850), or the weekly energy expenditure (p = 0.522). Infected professionals had a greater workload than non-infected ones, besides poorer sleep quality (10.46 ± 3.75 vs. 7.88 ± 3.75; p = 0.001) and excessive daytime sleepiness (10.19 ± 3.05 vs. 8.44 ± 3.85; p = 0.016). Conclusion Based on the results, this study shows that professionals infected with COVID-19 have poorer sleep quality, associated with excessive daytime sleepiness, in contrast with non-infected professionals.

Is breakfast consumption among Brazilian schoolchildren associated with an ultra-processed food dietary pattern?

Omission of breakfast starts at school age and can be explained as a reflection of the independent behaviour acquired in this phase of life. Breakfast has been investigated for its association with healthier diet quality, but few studies have investigated this relationship in schoolchildren aged 7 to 13 years. The objective of this study was to assess breakfast consumption in schoolchildren aged 7 to 13 years and to examine associations with dietary patterns (DPs). It was a cross-sectional study carried out in 2017 with 1069 students in Florianopolis, southern Brazil. Previous-day food consumption, physical activity and screen activities were self-reported. Factor analysis was used to identify DPs. Associations between breakfast consumption and overall DPs were evaluated using multivariate linear regression. Breakfast consumption was reported by 85% of the children, with the highest proportion observed among students on the afternoon school shift. Five DPs were identified explaining 41% of the total variance in daily food consumption: Ultra-processed, Mixed, Traditional Brazilian Lunch, Healthy + Sweets and Traditional Brazilian Breakfast. Breakfast consumption was directly associated with a Traditional Brazilian Breakfast DP (ß = 0.335; 95% CI = 0.227, 0.442), a Mixed DP (ß = 0.241; 95% CI = 0.160, 0.323), and a Healthy + Sweets DP (ß = 0.160; 95% CI = 0.061, 0.260), and inversely associated with an Ultra-processed DP (ß = -0.116; 95% CI = -0.207, -0.026). Breakfast consumption was associated with overall DPs, suggesting the importance of eating this meal by schoolchildren. We emphasise the relevance of offering a healthy breakfast at public schools for students who do not take this meal at home, contributing to health promotion.
