Abstract The objective of this cross-sectional study was to investigate whether total need satisfaction and three separate basic psychological needs (autonomy, competence and relatedness) predict life skills development in dual-career athletes according to sex, type of sport, type of higher education institution and financial support. Participants included 136 Brazilian university athletes (65 boys and 71 girls) aged 17–23 years. Data collection was conducted via Basic Needs Satisfaction in Sport Scale (BNSSS) and the Life Skills Scale for Sport (LSSS). Bayesian multilevel linear regression model found that total need satisfaction and three separate basic psychological needs (autonomy, competence and relatedness) influenced life skills (teamwork, social skills, leadership, goal setting and communication) and total life skills development in dual-career athletes. Total need satisfaction influenced leadership and total life skills. Competence and relatedness influenced goal seating, social skill, leadership and total life skills. Autonomy might not have a strong correlation with life skills development dimensions standardised scores and total life skills standardised score independent of sex, type of sport, type of higher education institution and financial support. Based on such findings, satisfaction of all three basic needs combined (total need satisfaction) and separate autonomy, competence and relatedness was positively associated with the development of life skills in dual-career athletes.

Abstract Objective To evaluate clinical characteristics and outcomes of COVID-19 patients infected with HIV, and to compare with a paired sample without HIV infection. Methods This is a substudy of a Brazilian multicentric cohort that comprised two periods (2020 and 2021). Data was obtained through the retrospective review of medical records. Primary outcomes were admission to the intensive care unit, invasive mechanical ventilation, and death. Patients with HIV and controls were matched for age, sex, number of comorbidities, and hospital of origin using the technique of propensity score matching (up to 4:1). They were compared using the Chi-Square or Fisher's Exact tests for categorical variables and the Wilcoxon for numerical variables. Results Throughout the study, 17,101 COVID-19 patients were hospitalized, and 130 (0.76%) of those were infected with HIV. The median age was 54 (IQR: 43.0;64.0) years in 2020 and 53 (IQR: 46.0;63.5) years in 2021, with a predominance of females in both periods. People Living with HIV (PLHIV) and their controls showed similar prevalence for admission to the ICU and invasive mechanical ventilation requirement in the two periods, with no significant differences. In 2020, in-hospital mortality was higher in the PLHIV compared to the controls (27.9% vs. 17.7%; p = 0.049), but there was no difference in mortality between groups in 2021 (25.0% vs. 25.1%; p > 0.999). Conclusions Our results reiterate that PLHIV were at higher risk of COVID-19 mortality in the early stages of the pandemic, however, this finding did not sustain in 2021, when the mortality rate is similar to the control group.

Abstract This study aimed to evaluate the contribution of oral and maxillofacial pathology laboratories (OMPLs) in Brazilian public universities to the diagnosis of lip, oral cavity, and oropharyngeal squamous cell carcinoma (SCC). A cross-sectional study was performed using biopsy records from a consortium of sixteen public OMPLs from all regions of Brazil (North, Northeast, Central-West, Southeast, and South). Clinical and demographic data of patients diagnosed with lip, oral cavity, and oropharyngeal SCC between 2010 and 2019 were collected from the patients’ histopathological records. Of the 120,010 oral and maxillofacial biopsies (2010-2019), 6.9% (8,321 cases) were diagnosed as lip (0.8%, 951 cases), oral cavity (4.9%, 5,971 cases), and oropharyngeal (1.2%, 1,399 cases) SCCs. Most cases were from Brazil’s Southeast (64.5%), where six of the OMPLs analyzed are located. The predominant profile of patients with lip and oral cavity SCC was Caucasian men, with a mean age over 60 years, low schooling level, and a previous history of heavy tobacco consumption. In the oropharyngeal group, the majority were non-Caucasian men, with a mean age under 60 years, had a low education level, and were former/current tobacco and alcohol users. According to data from the Brazilian National Cancer Institute, approximately 9.9% of the total lip, oral cavity, and oropharyngeal SCCs reported over the last decade in Brazil may have been diagnosed at the OMPLs included in the current study. Therefore, this data confirms the contribution of public OMPLs with respect to the important diagnostic support they provide to the oral healthcare services extended by the Brazilian Public Health System.

The control of fungal species in agriculture is mainly conducted with the use of contact or systemic fungicides. However, environmental and human health concerns and increased resistance of fungal species to existing fungicides have increased the pressure on researchers to find new active ingredients for fungal control which present low toxicity to non-target organisms, are environmentally safe, and can be applied at very low concentrations. It is herein described the synthesis of eleven glycerol triazole containing compounds (ten of them fluorinated derivatives) and evaluation of their fungicidal activity. Eight out of eleven synthesized compounds are novel and all of the glycerol derivatives were characterized using infrared (IR), nuclear magnetic ressonance (NMR), and mass spectrometry (MS) techniques. Theoretical calculations were also carried out and the results are discussed. Starting from glycerol, the triazole derivatives were prepared in four steps. Evaluation of them against Colletrotricum gloesporioides showed that compound 1-((2,2-dimethyl-1,3 dioxolan-4-yl)methyl)-4-(2-fluorophenyl)-1H-1,2,3-triazole (4d) (ED50 = 59.14 µg mL-1) was slightly more active than commercial fungicide tebuconazole (61.35 µg mL-1). Compound 4d presented attractive physicochemical features for agrochemical purposes as revealed by the calculated physicochemical parameters. It is believed that glycerol-fluorinated triazole derivatives can be explored towards the development of new chemicals for the control of fungal species.

ABSTRACT Although extrafloral nectaries (EFNs) are reported as extremely important to understand ecological interactions, the diversity of EFN-bearing plants remains underappreciated. In Brazil, studies are concentrated in Cerrado and extremely poorly known in other phytogeographic domains, such as Atlantic forest. Thus, this study provides one of the first checklists of angiosperms with EFNs in a protected area of the Brazilian Atlantic forest, bringing information about the richness, location of EFNs on the plant’s organs, as well as plant’s habit and conservation status. A total of 93 EFN-bearing species belonging to 61 genera and 29 families is reported, which corresponds to 16.5 % of the local flora. The vast majority has not been evaluated for their conservation status, and twenty species are endemic to the Brazilian Atlantic forest. Vines and trees are the predominant plant habits and EFNs are mostly found on leaves. More than half of the species (53.7 %) comprises new additions to the world list of EFN-bearing plants, including the first record in Dilleniaceae. Our findings show a large number of EFN-bearing plant species from a single and small protected area in the Brazilian Atlantic forest. It reinforces the lack of studies of this nature, where further investigations are strongly recommended.

Resumo Investigou-se a associação entre o consumo de álcool pelos escolares com os conflitos familiares, supervisão dos pais e qualidade dos relacionamentos. Estudo transversal realizado com 1.265 adolescentes de 21 escolas. Foi utilizada a versão brasileira do Inventário de Triagem do Uso de Drogas/DUSI e estimadas prevalências absolutas e relativas para variáveis categóricas, e conduzidas análises bivariadas: teste Qui Quadrado de Pearson. Para magnitude da associação entre a variável dependente e independentes foram estimadas razões de prevalências por meio deregressão multivariável de Poisson. Houve associação do consumo de álcool com uso de drogas por familiares, discussões frequentes e desconhecimento dos pais sobre o que os adolescentes fazem. Supervisão familiar, bom relacionamento com pais/responsáveis, estabelecimento de vínculo familiar afetivo e ciência dos pais acerca do que os adolescentes fazem e onde estão, foram fatores de proteção para uso de álcool. Concluiu-se que a alta taxa de escolares que consomem álcool é preocupante, passível de complicações da saúde na sua integralidade, sendo fundamental relação familiar harmonizada. A implementação de práticas interventivas entre escola e Estratégia de Saúde da Família, podem contribuir no estabelecimento de vínculo protetivo.

Abstract The association between alcohol consumption by students with family conflicts, parental supervision and quality of relationships was investigated. A cross-sectional study was conducted with 1,265 adolescents from 21 schools. The Brazilian version of the Drug Use Screening Inventory/DUSI was used, and absolute and relative prevalence for categorical variables was estimated, while bivariate analyses and Pearson’s Chi Square test were conducted. For the magnitude of the association between the dependent and independent variables, prevalence ratios were estimated using Poisson multivariate regression. There was an association between alcohol consumption and drug use by family members, frequent discussions and parental lack of awareness about adolescents’ activities. Family supervision, a good relationship with parents/guardians, establishing an affective family bond and parents’ knowledge about teenagers’ whereabouts, were protective factors for alcohol use. The conclusion was that the high rate of schoolchildren who consume alcohol is worrying, liable to health complications in general, and a harmonized family relationship is fundamental. The implementation of measures of intervention between school and the Family Health Strategy, can contribute to the establishment of a protective bond.

RESUMO Os canabinoides compreendem os endocanabinoides, fitocanabinoides e os canabinoides sintéticos e desempenham ações no sistema nervoso central e periférico. Uma quantidade enorme de publicações tem sido lançada nos últimos anos, embora a cannabis seja conhecida por milênios. Os Departamentos Científicos da Academia Brasileira de Neurologia descreveram as evidências do uso médico em suas áreas. A literatura está em constantes mudanças e possíveis novas evidências podem surgir nos próximos dias ou meses. A prescrição dessas substâncias deve ser discutida com os pacientes e suas famílias, com conhecimento sobre eventos adversos e sua eficácia.

ABSTRACT Cannabinoids comprehend endocannabinoids, phytocannabinoids, and synthetic cannabinoids, with actions both in the central and peripherical nervous systems. A considerable amount of publications have been made in recent years, although cannabis has been known for over a thousand years. Scientific Departments from the Brazilian Academy of Neurology described evidence for medical use in their areas. Literature is constantly changing, and possible new evidence can emerge in the next days or months. Prescription of these substances must be discussed with patients and their families, with knowledge about adverse events and their efficacy.

Resumo Este artigo examina o contexto e as implicações da pandemia por Covid-19 na cidade de Belo Horizonte (BH) nos primeiros 80 dias da doença. Utilizamos um recorte analítico descritivo para mensurar a evolução dos casos, o excesso de óbitos, a taxa de transmissibilidade do vírus e a pressão da doença sobre o sistema de saúde de BH e região, através da taxa de ocupação hospitalar nos leitos públicos. Além disso, identificamos as principais políticas de contenção adotadas pelas autoridades locais, bem como as implicações da redução do distanciamento social. Nossos resultados demonstram que o Sistema Único de Saúde (SUS), bem gerido, é fundamental para o enfrentamento da pandemia e a mitigação de suas consequências para a população. O processo de flexibilização que se inicia tem imposto novos desafios que requererão monitoramento atento das autoridades e da sociedade.

Abstract The paper examines the implications of Covid-19 pandemic for the city of Belo Horizonte (BH), during the first 80 days of the disease. We use a descriptive-analytical approach to estimate the growth of Covid-19 cases over time, the excess of deaths, the virus’ rate of transmissibility, and the consequent burden on the municipal the health system, measured by the rate of occupancy of public hospital beds. Also, we identify the main containment policies adopted by local authorities, and the implications of reopening measures and the following reduction of social distancing. Our findings reveal that a well-managed Unified Health System (SUS) is paramount to effectively tackle the pandemic and its consequences for the population. The reopening process has imposed new challenges that will require close monitoring by the authorities and by the society.

This work aims to develop a rapid and reliable method by HPLC-QqQ-MS/MS for identification and quantification of Kaurenoic acid (KA) in extract, tincture and syrup from Mikania glomerata. The developed method allows identifying and quantifying KA in complex samples obtained from extract marketed in pharmaceutical industry, a tincture prepared with the leaves from plant and two syrups purchased in the local market. The quantification was performed using standard addition calibration curve. An accurate method for Kaurenoic acid determination in M. glomerata samples was developed. The concentrations of KA found in M. glomerata were 0.19 mg mL-1 in the commercial extract, 0.93 mg mL-1 in the tincture, 3.00 x 10-3 mg mL-1 in the syrup B and in syrup A was not possible to quantify due to the concentration is below the detection limit. Since most reports describe the quantification of the main active constituent (coumarin) and do not provide relevant information on the quantification of KA in these sample types (syrup and tincture), the developed method represents an excellent alternative for agile and efficient analysis of the KA in complex matrices from simple dilution.

SUMMARY: The infrapatellar branch of the saphenous nerve is a cutaneous nerve that innervates the area surrounding the patella and contributes to the peripatellar plexus. This nerve is target to iatrogenic injuries during a great deal of knee procedures, such as tendon harvesting, total knee arthroplasty and medial arthroscopic approaches to the knee. Lesion to this nerve can produce sensorial loss at its innervation territory. The study conducted herein aims to observe the anatomical aspects of the infrapatellar branch in cadaveric specimens. The infrapatellar branch of the saphenous nerve of 40 male cadavers was dissected with the purpose of identifying the number of branches, its relation with the patella, tibial tuberosity and sartorius muscle. The nerve was dissected and several measurements were performed with the aid of a digital caliper. Statistical analysis was performed with the MedCalc 16.1 software. The infrapatellar branch of the saphenous nerve was present in 100 % of the sample. Its mean distance from its origin to its branching point was 16.35±6.48 mm on the right and 21.94±4.31 mm on the left, with statistically significant differences (p < 0.05). A relatively safe zone for surgery was observed on the superior and medial aspect of the patella, which received less branches.

RESUMEN: La rama infrapatelar del nervio safeno es un nervio cutáneo que inerva el área que rodea la patela y contribuye al plexo peripatelar. Este nervio es objeto de lesiones iatrogénicas durante una gran cantidad de procedimientos de rodilla, como la extracción de tendones, la artroplastía total de rodilla y los abordajes artroscópicos mediales de la rodilla. La lesión de este nervio puede producir pérdida sensorial en su territorio de inervación. El estudio realizado aquí tiene como objetivo observar los aspectos anatómicos de la rama infrapatelar en muestras de cadáveres. La rama infrapatelar del nervio safeno de 40 cadáveres masculinos se disecó con el propósito de identificar el número de ramas, su relación con la patela, la tuberosidad tibial y el músculo sartorio. Se disecó el nervio y se realizaron varias mediciones con la ayuda de un calibrador digital. El análisis estadístico se realizó con el software MedCalc 16.1. La rama infrapatelar del nervio safeno estaba presente en el 100 % de las muestras. La distancia media desde su origen hasta su punto de ramificación fue de 16,35±6,48 mm a la derecha y de 21,94±4,31 mm a la izquierda, con diferencias estadísticamente significativas (p <0,05). Se identificó una zona relativamente segura para la cirugía en el aspecto superior y medial de la patela, que recibió menos ramas.

Resumo Objetivou-se avaliar a adaptação de cultivares de alface com base na metodologia dos graus-dia, em estufa, no vale do Gurguéia. O experimento foi conduzido em ambiente protegido, na Universidade Federal do Piauí - UFPI/CPCE. O delineamento adotado foi em blocos ao acaso, sendo os tratamentos cultivares de alface. As cultivares utilizadas foram: Simpson, Bruna, Palmas e Grand Rapids - TBR. Os dados meteorológicos (temperatura do ar, umidade relativa, pressão atmosférica, velocidade dos ventos e precipitação) foram obtidos em uma estação meteorológica portátil que foi instalada no ambiente protegido. A temperatura do ar durante o experimento apresentou máxima de 33 °C e mínima de 26 °C. As cultivares ‘Simpson’ e ‘Grand Rapids’ apresentaram um ciclo mais precoce (45 dias), quando comparada às demais (52 dias), ambas com constante térmica (CT) de 898 °gd. As cultivares ‘Bruna’ e ‘Palmas’ apresentaram CT = 1050 °gd. Dentre as cultivares avaliadas, as cultivares ‘Palmas’ e ‘Bruna’ obtiveram comportamento e morfologia adequados em relação às altas temperaturas regionais. Dessa forma, conclui-se que as cultivares ‘Palmas’ e ‘Bruna’ possuem potencial produtivo para a região, quando cultivada em ambiente protegido.

Abstract The objective of this study was to evaluate the adaptation of lettuce cultivars based on day-degree greenhouse methods in the Gurguéia Valley. The experiment was carried out in a protected environment, at the Federal University of Piauí - UFPI / CPCE. The experimental design was a randomized block design, with treatments of lettuce cultivars. The cultivars used were: Simpson, Bruna, Palmas and Grand Rapids - TBR. The meteorological data (air temperature, relative humidity, atmospheric pressure, wind velocity and precipitation) were obtained in a portable weather station that was installed in the protected environment. The temperature of the air during the experiment presented maximum of 33 °C and minimum of 26 °C. The cultivars ‘Simpson’ and ‘Grand Rapids’ presented an earlier cycle (45 days), when compared to the others (52 days), both with a thermal constant (CT) of 898 °gd. The cultivars ‘Bruna’ and ‘Palmas’ showed CT = 1050 °gd. Among the evaluated cultivars, the ‘Palmas’ and ‘Bruna’ cultivars obtained adequate behavior and morphology in relation to the high regional temperatures. Thus, it is concluded that the ‘Palmas’ and ‘Bruna’ cultivars have productive potential for the region when cultivated in a protected environment.

Abstract Vitamin D exerts an immuno-modulatory activity on several immune system cells through the vitamin D receptor (VDR). Herein, we verified that age and a therapeutic regimen containing protease inhibitors are associated with failures in antiretroviral therapies (ARVs). In addition, we assessed whether a VDR SNP (rs11568820: C allele and CC genotype) and GC (rs2228570-rs11568820) allelic combinations are associated with immunological failure (p < 0.05). Our findings suggest a possible role of VDR SNPs on immunological failure in HIV-1+ individuals undergoing regular ARVs.

ABSTRACT Background: Zika, a disease caused by Zika virus infections, has recently emerged and caused outbreaks in many parts of the world. The clinical manifestations of Zika are usually mild, mostly presenting as an exanthematic febrile disease, but on some occasions, it might be associated with microcephaly after intrauterine infection, and Guillain-Barré Syndrome. Zika virus is primarily transmitted by mosquito bites, but other means of transmission have been described, and potential risk for blood transmission has been reported in French Polynesia and Brazil. Methods: To investigate the risk of Zika virus infection after a blood transfusion in an area of Brazil where a possible transmission by a platelet concentrate has been described. Using a mini-pool format, 1857 blood donations were evaluated by real-time reverse transcriptase polymerase chain reaction designed to detect Zika virus RNA. Results: After testing samples individually from positive mini-pools, the prevalence of Zika virus RNA was only 0.16%, a result probably associated to the low circulation of this virus in the study area. In addition, it was evident that the implementation of post-surveillance programs is important to detect Zika virus infections in blood donors, as the post-donation surveillance program detected two blood donors with the disease in this study. Conclusion: This study shows that the risk for Zika virus transmission by blood transfusion is real, even in regions with a low circulation of the disease, but the combination of the detection of Zika virus RNA by polymerase chain reaction and post-donation surveillance might reduce the risk of transmission by blood transfusions.

ABSTRACT It is well known that phytochromes mediate a wide range of photomorphogenic processes in plants. In addition, many studies have demonstrated the involvement of phytochromes as part of abiotic stress signaling responses. However, little is known about cadmium (Cd) stress regulation by phytochromes. Thus, in this study, we used the phyA (far red-insensitive; fri), phyB1 (temporary redinsensitive; tri) and phyB2 (phyB2) tomato (Solanum lycopersicum L.) mutants to investigate the roles of these three phytochromes on Cd stress responses. The plants were grown over a 21-d period in the presence of Cd. We evaluated plant growth, Cd and chlorophyll content and anatomical changes in the leaves. The results indicated that all genotypes were affected by Cd and showed reduced growth of the shoots and roots, as well as reduced chlorophyll content. The accumulation of Cd was similar for all genotypes, and a higher Cd content was found in roots. Anatomical analysis of the vascular bundles revealed that fri and tri seem to be more disrupted by Cd. Overall, these results indicate that phytochromes do not determine Cd stress tolerance in tomato plants.
