Tropical peanut maturation scale for harvesting seeds with superior quality.

Determining the moment for harvesting the tropical peanut with a focus on superior seed quality is not an easy task. Particularities such as indeterminate flowering, underground fruiting and uneven maturation further increase this technical challenge. It is in this context that we aim to investigate harvest indicators based on the maturation and late maturation phases of tropical peanuts to obtain seeds with superior physiological and health quality. The plants were grown in field conditions and their development stages were carefully monitored until seed production. The water content, dry weight, germination capacity, desiccation tolerance, vigor, longevity, and seed pathogens were evaluated throughout these stages. We showed that seeds from early stages (R5 and R6) did not fully tolerate desiccation and were highly sensitive to pathogen contamination after storage (Aspergillus, Penicillium, and Bacteria). At late stages (R7, R8, and R9), the seeds had optimized vigor, longevity and bioprotection against fungi and thermal stress. The peanut maturation scale for tropical agriculture provides unique harvesting guidelines that make it possible to monitor the plants' development stages with a focus on producing superior quality seeds.

Ad libitum ice slurry ingestion and half-marathon performance in a hot environment: A study comparing the effects of the amount and moment of ingestion between ice slurry and water at 37 °C.

Ice slurry ingestion during prolonged exercises may improve performance in hot environments; however, the ideal amount and timing of ingestion are still uncertain. We determined whether ad libitum ice slurry ingestion influences physiological and perceptual variables and half-marathon performance while comparing the effects of the amount and moment of ingestion between ice slurry and water at 37 °C. Ten trained participants (28 ± 2 years; mean and SD) were required to run two half marathons while consuming either ice slurry (-1 °C; Ad-1) or water (37 °C; 37 CE) ad libitum. They then performed two other half marathons where, during one, they were required to ingest an amount of water equivalent to the amount consumed during the Ad-1 trial (Pro37), and in the other, to ingest ice slurry in the amount consumed during the 37 CE trial (Pro-1). During the half marathons, dry-bulb temperature and relative humidity were controlled at 33.1 ± 0.3 °C and 60 ± 3%, respectively. Ad-1 ingestion (349.6 ± 58.5 g) was 45% less than 37 CE ingestion (635.5 ± 135.8 g). Physical performance, heart rate, perceived exertion, body temperatures, and thermal perception were not influenced by the temperature or amount of beverage ingestion. However, a secondary analysis suggested that lower beverage ingestion was associated with improved performance (Ad-1 + Pro37 vs. 37 CE + Pro-1: -4.0 min, Cohen's d = 0.39), with a significant relationship between lower beverage ingestion and faster running time (b = 0.02, t = 4.01, p < 0.001). In conclusion, ice slurry ingestion does not affect performance or physiological or perceptual variables during a half marathon in a hot environment. Preliminary evidence suggests that lower beverage ingestion (ice slurry or warm water) is associated with improved performance compared to higher ingestion.

Hyaluronic Acid Dermal Fillers for Treatment of Congenital and Acquired Lip Asymmetries and Deformities

Hyaluronic acid (HA) dermal fillers are widely used in aesthetic treatments for facial and lip modeling. Despite HA fillers has largely known to be use in procedures for augmentation the lip volume, their application to management lip abnormalities is not widespread. This study reviewed the use of HA fillers for reconstruction of congenital and acquired li p asymmetries and deformities, searching to expand knowledge about this treatment modality. To undertake this narrative review, the Medline-Pubmed, Web of Science, Scopus, Embase, Google Schoolar e Lillacs databases were searched. Several studies have reported positive results in the use of HA fillers for the treatment of lip deformities caused by different factors such as: Insatisfactory dermal fillers, permanent lip implants, excision of lip carcinoma, post-operative scars and electrical burns. HA fillers are also an alternative for the management of lip asymmetries and residual surgical scars in patients with cleft lip. Moreover, injection of HA fillers in individuals with facial paralysis and facioscapulohumeral muscular dystrophy can also improve lip incompetence. Additionally, HA fillers can be used as a complementary treatment in cases of severe malocclusion associated with skeletal changes, helping to maintain the seal and refine the lip appearance. Therefore, HA fillers can be used as alternative treatment for several types of congenital and acquired lip deformities and asymmetries. However, it is necessary to carry out randomized clinical trials with a greater number of patients and follow-up time, in order to investigate the benefits of the HA fillers for carriers patients of lip abnormalities.

Los rellenos dérmicos de ácido hialurónico (AH) son muy utilizados en tratamientos estéticos para el modelado facial y de labios. A pesar de que se sabe en gran medida que los rellenos de HA se utilizan en procedimientos para aumentar el volumen de los labios, su aplicación para el tratamiento de anomalías labiales no está muy extendida. Este estudio revisó el uso de rellenos de HA para la reconstrucción de asimetrías y deformidades labiales congénitas y adquiridas, buscando ampliar el conocimiento sobre esta modalidad de tratamiento. Para realizar esta revisión narrativa, se realizaron búsquedas en las bases de datos Medline-Pubmed, Web of Science, Scopus, Embase, Google Schoolar y Lillacs. Varios estudios han reportado resultados positivos en el uso de rellenos de HA para el tratamiento de deformidades labiales causadas por diferentes factores tales como: rellenos dérmicos insatisfactorios, implantes labiales permanentes, escisión de carcinoma labial, cicatrices postoperatorias y quemaduras eléctricas. Los rellenos de HA también son una alternativa para el manejo de asimetrías labiales y cicatrices quirúrgicas residuales en pacientes con labio hendido. Además, la inyección de rellenos de HA en personas con parálisis facial y distrofia muscular facioescapulohumeral también puede mejorar la incompetencia de los labios. Además, los rellenos de HA se pueden usar como un tratamiento complementario en casos de maloclusión severa asociada con cambios esqueléticos, lo que ayuda a mantener el sellado y refinar la apariencia de los labios. Por lo tanto, los rellenos de HA se pueden utilizar como tratamiento alternativo para varios tipos de deformidades y asimetrías labiales congénitas y adquiridas. Sin embargo, es necesario realizar ensayos clínicos aleatorizados con mayor número de pacientes y tiempo de seguimiento, para investigar los beneficios de los rellenos HA para pacientes portadores de anomalías labiales.

The hospital Israelita Albert Einstein standards for constitutional sequence variants classification: version 2023.

BACKGROUND: Next-generation sequencing has had a significant impact on genetic disease diagnosis, but the interpretation of the vast amount of genomic data it generates can be challenging. To address this, the American College of Medical Genetics and Genomics and the Association for Molecular Pathology have established guidelines for standardized variant interpretation. In this manuscript, we present the updated Hospital Israelita Albert Einstein Standards for Constitutional Sequence Variants Classification, incorporating modifications from leading genetics societies and the ClinGen initiative. RESULTS: First, we standardized the scientific publications, documents, and other reliable sources for this document to ensure an evidence-based approach. Next, we defined the databases that would provide variant information for the classification process, established the terminology for molecular findings, set standards for disease-gene associations, and determined the nomenclature for classification criteria. Subsequently, we defined the general rules for variant classification and the Bayesian statistical reasoning principles to enhance this process. We also defined bioinformatics standards for automated classification. Our workgroup adhered to gene-specific rules and workflows curated by the ClinGen Variant Curation Expert Panels whenever available. Additionally, a distinct set of specifications for criteria modulation was created for cancer genes, recognizing their unique characteristics. CONCLUSIONS: The development of an internal consensus and standards for constitutional sequence variant classification, specifically adapted to the Brazilian population, further contributes to the continuous refinement of variant classification practices. The aim of these efforts from the workgroup is to enhance the reliability and uniformity of variant classification.

Matricide and schizophrenia- psychopathological, psychodynamic, and forensic aspects: a case report.

Matricide is the murder of a mother by her son or daughter, a form of homicide rarely seen in psychiatric practice. A narrative review was conducted on the relationship between matricide and schizophrenia, followed by a case report in Brazil of a schizophrenic patient who murdered his mother and was submitted to forensic psychiatric assessment for criminal liability. The article discusses psychopathological, psychodynamic, and forensic aspects related to the case. The observation of ambivalent and conflictive relations between schizophrenic individuals and their mothers suggests the need for family-level interventions to resolve the understandable occurrence of emotional conflicts, which can serve as stimuli that trigger the murder.

Antimicrobial activity of cinnamaldehyde against multidrug-resistant Klebsiella pneumoniae: an in vitro and in vivo study.

The emergence and spread of multidrug-resistant (MDR) Klebsiella pneumoniae strains have increased worldwide, posing a significant health threat by limiting the therapeutic options. This study aimed to investigate the antimicrobial potential of cinnamaldehyde against MDR-K. pneumoniae strains in vitro and in vivo assays. The presence of resistant genes in MDR- K. pneumoniae strains were evaluated by Polymerase Chain Reaction (PCR) and DNA sequencing. Carbapenem-resistant K. pneumoniae strains show the blaKPC-2 gene, while polymyxin-resistant K. pneumoniae presented blaKPC-2 and alterations in the mgrB gene. Cinnamaldehyde exhibited an inhibitory effect against all MDR- K. pneumoniae evaluated. An infected mice model was used to determine the in vivo effects against two K. pneumoniae strains, one carbapenem-resistant and another polymyxin-resistant. After 24 h of cinnamaldehyde treatment, the bacterial load in blood and peritoneal fluids decreased. Cinnamaldehyde showed potential effectiveness as an antibacterial agent by inhibiting the growth of MDR-K. pneumoniae strains.

Effectiveness and safety of multidrug therapy containing clofazimine for paucibacillary leprosy and clarithromycin for rifampicin-resistant leprosy: a systematic review and meta-analysis.

Introduction: The present study aimed to evaluate leprosy cure and relapse rates as primary outcomes related to two additional strategies for leprosy treatment: clofazimine for paucibacillary (PB) leprosy patients and clarithromycin for patients with rifampicin-resistant leprosy. Methods: We conducted two systematic reviews (protocols CRD42022308272 and CRD42022308260). We searched the PubMed, EMBASE, Web of Science, Scopus, LILACS, Virtual Health Library and Cochrane Library databases, registers of clinical trial databases and gray literature. We included clinical trials evaluating the addition of clofazimine to PB leprosy treatment and the use of clarithromycin for treating patients with rifampicin-resistant leprosy. Risk of bias (RoB) in randomized clinical trials was assessed by the RoB 2 tool and that in non-randomized clinical trials was assessed by the ROBINS-I tool; and the certainty of the evidence was assessed by the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. A meta-analysis of dichotomous outcomes was performed. Results: For clofazimine, four studies were included. Cure and relapse rates were not different with the addition of clofazimine to PB leprosy treatment and demonstrated very low certainty of evidence. For clarithromycin, six studies were included. Considerable heterogeneity resulted from the difference between comparators, and studies showed no difference in the assessed outcomes with the addition of clarithromycin to rifampicin-resistant leprosy treatment. Mild adverse events were reported for both drugs but did not significantly impact treatment. Discussion: The effectiveness of both drugs still needs to be determined. Adding clofazimine to PB leprosy treatment may reduce the repercussions of an incorrect operational classification with no apparent relevant side effects.

Fungal identification in peanuts seeds through multispectral images: Technological advances to enhance sanitary quality.

The sanitary quality of seed is essential in agriculture. This is because pathogenic fungi compromise seed physiological quality and prevent the formation of plants in the field, which causes losses to farmers. Multispectral images technologies coupled with machine learning algorithms can optimize the identification of healthy peanut seeds, greatly improving the sanitary quality. The objective was to verify whether multispectral images technologies and artificial intelligence tools are effective for discriminating pathogenic fungi in tropical peanut seeds. For this purpose, dry peanut seeds infected by fungi (A. flavus, A. niger, Penicillium sp., and Rhizopus sp.) were used to acquire images at different wavelengths (365 to 970 nm). Multispectral markers of peanut seed health quality were found. The incubation period of 216 h was the one that most contributed to discriminating healthy seeds from those containing fungi through multispectral images. Texture (Percent Run), color (CIELab L*) and reflectance (490 nm) were highly effective in discriminating the sanitary quality of peanut seeds. Machine learning algorithms (LDA, MLP, RF, and SVM) demonstrated high accuracy in autonomous detection of seed health status (90 to 100%). Thus, multispectral images coupled with machine learning algorithms are effective for screening peanut seeds with superior sanitary quality.

New Cretaceous (Aptian/Albian) boxer shrimp (Crustacea, Decapoda, Stenopodidea) from the Araripe Sedimentary Basin, NE, Brazil.

Stenopodidean shrimps are mostly cryptic in their habitats and are typically related with coral rubble or dead coral heads, rocks and crevices, and in association with other marine invertebrate such as sponges, crinoids and corals. Here, we describe a new stenopodidean shrimp, Dubiostenopus parvus n. gen. n. sp., from the Romualdo Formation (Aptian/Albian), Araripe Sedimentary Basin. The specimen studied here was collected in the municipality of Trindade, Pernambuco State, Brazil. The specimen is the imprint of a small shrimp approximately 10 mm in length, with a robust cephalothorax, a well-developed cheliped in the third pereiopod, and a second pleura not overlapping the first. This is the first stenopodidean shrimp described from the Romualdo Formation and the first described from South America. Comparisons with other Brazilian shrimp-like fossils are made, as well as comparisons with all other fossil stenopodideans.

Association between Femoral Artery Flow-Mediated Dilation and Muscle Oxygen Saturation Parameters in Healthy, Young Individuals.

Flow-mediated dilation (FMD) and muscle oxygen saturation (StO2) are measurements utilized to assess macro- and microvascular function, respectively. Macro- and microvascular dysfunction may occur differently depending on the clinical condition. Since microvascular responsiveness can influence upstream conduit artery hemodynamics, the present study aimed to investigate whether a correlation between FMD and muscle StO2 parameters exists. Sixteen healthy, young individuals were enrolled in this study. Femoral artery FMD and tibial anterior muscle StO2 were evaluated by ultrasound and near-infrared spectroscopy, respectively. The FMD and muscle StO2 parameters were assessed by employing a vascular occlusion test (VOT). The oxygen resaturation rate was determined by calculating the upslope of StO2 immediately after occlusion and the magnitude of reperfusion as the difference between the highest and lowest StO2 value achieved during the reperfusion phase. The oxygen desaturation rate and the magnitude of desaturation during the VOT were also evaluated. A significant correlation between the FMD and oxygen resaturation rate (r = 0.628; p = 0.009), magnitude of reperfusion (r = 0.568; p = 0.022), oxygen desaturation rate (r = -0.509; p = 0.044), and magnitude of desaturation (r = 0.644; p = 0.007) was observed. This study demonstrated a moderate association between the femoral artery FMD and tibial anterior StO2 parameters in young individuals.

Cessation of dangerousness status in Brasília, Brazil: An analysis of 144 reports from Federal District Medical Examiner's Office in the last 10 years.

The aim of this study is to evaluate factors related to cessation of dangerousness of individuals under safety measures, through the study of psychiatric reports. This is a cross-sectional study, conducted through a retrospective analysis of expert psychiatric dangerousness cessation reports issued by the Federal District Coroner's Office, Brasília, Brazil. By examining official files, information was extracted from the reports (socio-demographic data, clinical characteristics, type of crime, historical characteristics and the search for items related to risk assessment present in instruments such as Historical, Clinical and Risk Management [HCR-20], Psychopathy Checklist - Revised [PCL-R], Two-Tiered Violence Risk Scale [TTV], Short-Term Assessment of Risk and Treatability [START] and others) and submitted to statistical analysis and then compared to other studies on the subject. The items most considered by the experts were those referring to PCL-R, START and the "non static" part of HCR-20 and TTV. For the non-cessation of dangerousness, we've found: absence of remorse, fragile behavioral control, early behavioral problems, juvenile delinquency. For the cessation of dangerousness, we've found: presence of social skills, balanced emotional state, presence of social support, adherence to rules, good coping strategies, involvement with treatment and adherence. The systematization and standardization of forensic psychiatric reports needs to be established and the use of risk assessment instruments are essential to support better decisions by the experts.

Osteohistological characterization of notosuchian osteoderms: Evidence for an overlying thick leathery layer of skin.

Osteoderms are mineralized structures embedded in the dermis, known for nonavian archosaurs, squamates, xenarthrans, and amphibians. Herein, we compared the osteoderm histology of Brazilian Notosuchia of Cretaceous age using three neosuchians for comparative purposes. Microanatomical analyses showed that most of them present a diploe structure similar to those of other pseudosuchians, lizards, and turtles. This structure contains two cortices (the external cortex composed of an outer and an inner layers, and the basal cortex) and a core in-between them. Notosuchian osteoderms show high bone compactness (>0.85) with varying degrees of cancellous bone in the core. The neosuchian Guarinisuchus shows the lowest bone compactness with a well-developed cancellous layer. From an ontogenetic perspective, most tissues are formed through periosteal ossification, although the mineralized tissues observed in baurusuchid LPRP/USP 0634 suggest a late metaplastic development. Histology suggests that the ossification center of notosuchian osteoderm is located at the keel. Interestingly, we identified Sharpey's fibers running perpendicularly to the outer layer of the external cortex in Armadillosuchus arrudai, Itasuchus jesuinoi, and Baurusuchidae (LPRP/USP 0642). This feature indicates a tight attachment within the dermis, and it is evidence for the presence of an overlying thick leathery layer of skin over these osteoderms. These data allow a better understanding of the osteohistological structure of crocodylomorph dermal bones, and highlight their structural diversity. We suggest that the vascular canals present in some sampled osteoderms connecting the inner layer of the external cortex and the core with the external surface may increase osteoderm surface and the capacity of heat transfer in terrestrial notosuchians.

Effect of microencapsulated watermelon (Citrullus Lanatus) rind on flow-mediated dilation and tissue oxygen saturation of young adults.

BACKGROUND/OBJECTIVES: Watermelon rind (usually discarded by consumers) presents a high L-citrulline content. Given that Lcitrulline is involved in nitric oxide (NO) synthesis, a crucial molecule that regulates vascular function, this study aimed to evaluate the effect of microencapsulated watermelon rind (MWR) on endothelial function and tissue oxygen saturation (StO2) assessed by flow-mediated dilation (FMD) and near-infrared spectroscopy, respectively. Plasma L-arginine and L-citrulline were also evaluated. SUBJECT/METHODS: Eleven participants ingested 30 g of MWR (containing 4 g of L-citrulline) and a placebo. Before and 30, 60, 90, and 120 min after ingestion, StO2 parameters were assessed, whereas FMD and plasma amino acids were analyzed 60 and 120 min after ingestion. RESULTS: The FMD improved 60 min after MWR without changes in StO2 parameters. Absolute plasma L-citrulline and relative change from baseline in plasma L-arginine increased 60 min after MWR ingestion. CONCLUSION: A single dose of microencapsulated watermelon rind containing 4 g of L-citrulline seems adequate to improve FMD response, but not StO2 parameters in healthy adults. (NCT04781595).

The Role of By-Products of Fruit and Vegetable Processing for the Dietary Treatment of Cardiovascular Risk Factors: A Narrative Review.

Polyphenols-rich food has been utilized to induce a positive effect on human health. Considering that fruit and vegetable by-products (seeds, pomace, and peels) are sources of polyphenols, previous studies have investigated the effect of dietary supplementation with food by-products on cardiometabolic disorders, such as high fasting blood glucose, dyslipidemia, and obesity. Endothelial dysfunction has also been considered a cardiometabolic parameter, given that it precedes cardiovascular disease. However, there is a scarcity of narrative reviews reporting the effect of food by-product supplementation on cardiometabolic disorders in animal and human clinical trials. In this sense, the present narrative review aims to investigate the impact of fruit and vegetable by-product supplementation on cardiometabolic disorders in humans and animals, exploring the possible mechanisms whenever possible. Research articles were retrieved based on a search of the following databases: PubMed, ScienceDirect, and Google Scholar using the following keywords and synonyms combined: ("fruit by-products" or "food waste" or "pomace" or "bagasse" or "seeds" or "waste products") AND ("heart disease risk factors" or "endothelial dysfunction" or "atherosclerosis"). It was shown that fruit and vegetable by-products could efficiently improve cardiometabolic disorders in patients with chronic diseases, including hypertension, type II diabetes mellitus, and dyslipidemia. Such effects can be induced by the polyphenols present in food by-products. In conclusion, food by-product supplementation has a positive effect on cardiometabolic disorders. However, further studies investigating the effect of food by-products on cardiometabolic disorders in humans are still necessary so that solid conclusions can be drawn.

Quality of cowpea seeds: A food security strategy in the tropical environment.

What is the relation between seed quality and food security? Here we built a summary diagram that links the development stages of the seeds with their potential of providing grain yield. This idea was tested using cowpea as a model crop, grown in a tropical environment. Initially, seed quality attributes such as water content, dry weight, germination, vigor, and longevity were characterized during seed development. With this, we were able to elucidate at which point the late maturation phase and the acquisition of seed with superior physiological quality starts. From these data, the proposed summary diagram highlighted the seed quality as a technological basis for generating a more productive plant community. It also showed that only seeds with a high-quality profile have a better chance to establishment in an increasingly challenging agricultural environment. Overall, we bring the concept that cowpea seeds with superior quality besides being the essential input for tropical agriculture is also a strategy that can contribute food security.

Liming enhances longevity of wheat seeds produced in acid soils.

The environment where plants grow, such as acidic soils, interferes with the nutrient concentration and physiological quality of seeds. This hypothesis was tested using wheat seeds as a model crop, grown in a tropical soil with and without lime application for twelve years. Here we show that lime provides remarkable enhancements in soil chemistry and seed composition, without altering the seed's germination and vigor. Also, it favors the production of seeds with additional molecular mechanisms that extend their longevity. Our results indicate that the application of lime mitigates acidity in tropical soils and ensures the production of seeds with enhanced chemical composition and longer life span.

A Reliable Method to Recognize Soybean Seed Maturation Stages Based on Autofluorescence-Spectral Imaging Combined With Machine Learning Algorithms.

In recent years, technological innovations have allowed significant advances in the diagnosis of seed quality. Seeds with superior physiological quality are those with the highest level of physiological maturity and the integration of rapid and precise methods to separate them contributes to better performance in the field. Autofluorescence-spectral imaging is an innovative technique based on fluorescence signals from fluorophores present in seed tissues, which have biological implications for seed quality. Thus, through this technique, it would be possible to classify seeds in different maturation stages. To test this, we produced plants of a commercial cultivar (MG/BR 46 "Conquista") and collected the seeds at five reproductive (R) stages: R7.1 (beginning of maturity), R7.2 (mass maturity), R7.3 (seed disconnected from the mother plant), R8 (harvest point), and R9 (final maturity). Autofluorescence signals were extracted from images captured at different excitation/emission combinations. In parallel, we investigated physical parameters, germination, vigor and the dynamics of pigments in seeds from different maturation stages. To verify the accuracy in predicting the seed maturation stages based on autofluorescence-spectral imaging, we created machine learning models based on three algorithms: (i) random forest, (ii) neural network, and (iii) support vector machine. Here, we reported the unprecedented use of the autofluorescence-spectral technique to classify the maturation stages of soybean seeds, especially using the excitation/emission combination of chlorophyll a (660/700 nm) and b (405/600 nm). Taken together, the machine learning algorithms showed high performance segmenting the different stages of seed maturation. In summary, our results demonstrated that the maturation stages of soybean seeds have their autofluorescence-spectral identity in the wavelengths of chlorophylls, which allows the use of this technique as a marker of seed maturity and superior physiological quality.

Forecasting models for leprosy cases: a scoping review protocol.

INTRODUCTION: Leprosy is a neglected tropical disease caused by Mycobacterium leprae that mainly affects the skin, the peripheral nerves, the mucosa of the upper respiratory tract and the eyes. Mathematical models and statistical methodologies could play an important role in decision-making and help maintain the gains in elimination programmes. Various models for predicting leprosy cases have been reported in the literature, but they have different settings and distinct approaches to predicting the cases. This study describes the protocol for a scoping review to identify and synthesise information from studies using models to forecast leprosy cases. METHODS AND ANALYSIS: A scoping review methodology will be applied following the Joanna Briggs Institute methodology for scoping reviews and will be reported according to Preferred Reporting Items for Systematic Reviews and Meta-analysis Extension for Scoping Reviews. We will perform a systematic search from when each database started until April 2022 and we will include the following electronic databases: MEDLINE via PubMed, Embase, Cochrane Library and Latin American and Caribbean Health Science Literature Database. Data will be extracted and recorded on a calibrated predefined data form and will be presented in a tabular form accompanied by a descriptive summary. The Prediction Model Study Risk of Bias Assessment Tool (PROBAST) will be used. ETHICS AND DISSEMINATION: No ethical approval is required for this study. This scoping review will identify and map the methodological and other characteristics of modelling studies predicting leprosy cases. We hope that the review will contribute to scientific knowledge in this area and act as a basis for researchers designing and conducting leprosy models. This information can also be used to enhance national surveillance systems and to target specific policies. The protocol and consequent publications of this scoping review will be disseminated through peer-reviewed publications and policy briefs. SYSTEMATIC REVIEW REGISTRATION: This scoping review was registered in the Open Science Framework (https://doi.org/10.17605/OSF.IO/W9375).

Cardiovascular, Respiratory, and Functional Effects of Home-Based Exercise Training after COVID-19 Hospitalization.

INTRODUCTION: The present randomized, single-center, and single-blinded clinical trial tested the hypothesis that tele-supervised home-based exercise training (exercise) is an effective strategy for improving cardiovascular, respiratory, and functional capacity parameters in individuals who were hospitalized due to coronavirus disease 2019 (COVID-19). METHODS: Thirty-two individuals (52 ± 10 yr; 17 were female) randomly assigned to exercise ( n = 12) or control groups ( n = 20) had their anthropometric (weight, body mass index), hemodynamic (brachial and central blood pressure), vascular (arterial stiffness), ventilatory (pulmonary function and respiratory muscle strength), and functional parameters (handgrip strength, five-time sit to stand, timed up and go test, and 6-min walking test) assessed at baseline (30-45 d of hospital discharged) and after 12 wk of follow-up. RESULTS: Both groups similarly increased ( P < 0.001) forced vital capacity (absolute and percent of predicted), forced expiratory volume in the first second (absolute and percent of predicted), and handgrip strength during follow-up. However, only the exercise group reduced carotid-femoral pulse wave velocity (-2.0 ± 0.6 m·s -1 , P = 0.048) and increased ( P < 0.05) resting oxygen saturation (1.9% ± 0.6%), mean inspiratory pressure (24.7 ± 7.1 cm H 2 O), mean expiratory pressure (20.3 ± 5.8 cm H 2 O), and percent of predicted mean expiratory pressure (14% ± 22%) during follow-up. No significant changes were found in any other variable during follow-up. CONCLUSIONS: Present findings suggest that tele-supervised home-based exercise training can be a potential adjunct therapeutic to rehabilitate individuals who were hospitalized due to COVID-19.

Improved microvascular reactivity after aged garlic extract intake is not mediated by hydrogen sulfide in older adults at risk for cardiovascular disease: a randomized clinical trial.

PURPOSE: This study aimed to investigate the effects of AGE on microvascular reactivity, systolic blood pressure (SBP), and diastolic blood pressure (DBP) in older individuals at high risk for cardiovascular disease (CVD). Urinary thiosulfate was also investigated as an indirect marker of endogenous hydrogen sulfide (H2S) synthesis. The study was conducted in a randomized, double-blind, crossover, and placebo-controlled way. METHODS: Twenty-eight participants (14 male), 67 ± 6 years old with CVD risk factors, ingested 2.4 g of AGE or placebo (PLA). Near-infrared spectroscopy evaluated tissue oxygen saturation (StO2) during a vascular occlusion test (30 s baseline, 5 min occlusion, and 2 min reperfusion). The upslope of StO2 signal after cuff release was calculated to measure microvascular reactivity. Urinary thiosulfate levels were measured using a high-performance liquid chromatography system. RESULTS: The upslope of StO2 was significantly faster after AGE (1.01 ± 0.37% s-1) intake compared to PLA (0.83 ± 0.35% s-1; P < 0.001; d = 0.50). Relative changes in Δ% SBP from pre- to post-AGE intake (- 5.17 ± 5.77%) was significantly different compared to Δ% PLA (0.32 ± 5.99%; P = 0.001; d = 0.93). No significant changes in urinary thiosulfate concentrations were observed between interventions. Moreover, no significant gender effect in any parameter assessed was found. CONCLUSION: This study demonstrated that a single dose of AGE improved microvascular reactivity in older adults at risk of CVD despite such an effect was not linked with urinary thiosulfate levels. This trial was registered at clinicaltrials.gov as NCT04008693 (May 19, 2020).
