Visceral Leishmaniasis Revealing Undiagnosed Inborn Errors of Immunity.

Visceral Leishmaniasis (VL) is a potentially fatal disease and may be associated with primary or acquired immunodeficiencies. There are few reports, in the literature, of inborn errors of immunity. Here, we report two cases of VL as a marker of inborn errors of immunity, namely, GATA2 and RAB27A deficiency. Our data suggest that VL patients should be screened for primary immunodeficiency, particularly in cases of VL relapse.

Inhibition of O-GlcNAcylation Reduces Cell Viability and Autophagy and Increases Sensitivity to Chemotherapeutic Temozolomide in Glioblastoma.

Glioblastoma (GB) is the most aggressive primary malignant brain tumor and is associated with short survival. O-GlcNAcylation is an intracellular glycosylation that regulates protein function, enzymatic activity, protein stability, and subcellular localization. Aberrant O-GlcNAcylation is related to the tumorigenesis of different tumors, and mounting evidence supports O-GlcNAc transferase (OGT) as a potential therapeutic target. Here, we used two human GB cell lines alongside primary human astrocytes as a non-tumoral control to investigate the role of O-GlcNAcylation in cell proliferation, cell cycle, autophagy, and cell death. We observed that hyper O-GlcNAcylation promoted increased cellular proliferation, independent of alterations in the cell cycle, through the activation of autophagy. On the other hand, hypo O-GlcNAcylation inhibited autophagy, promoted cell death by apoptosis, and reduced cell proliferation. In addition, the decrease in O-GlcNAcylation sensitized GB cells to the chemotherapeutic temozolomide (TMZ) without affecting human astrocytes. Combined, these results indicated a role for O-GlcNAcylation in governing cell proliferation, autophagy, cell death, and TMZ response, thereby indicating possible therapeutic implications for treating GB. These findings pave the way for further research and the development of novel treatment approaches which may contribute to improved outcomes and increased survival rates for patients facing this challenging disease.

Pertussis antibodies and vaccination coverage among healthcare professionals in Brazil is inadequate: A cross-sectional serological study.

INTRODUCTION: Worldwide, tetanus-diphtheria-acellular pertussis (Tdap) vaccination coverage of healthcare professionals (HCPs) is below 40%, but this data is not available for Brazil. We hypothesize that a high number of HCPs are not immune to pertussis in Brazil. Main objective was to determine the seroprevalence of anti-pertussis toxin (anti-PT IgG) among HCPs. Secondary objectives were to evaluate Tdap vaccination coverage, to assess predictive factors associated with anti-PT IgG, and to estimate the decay of anti-PT IgG and time to Tdap vaccination. METHODS: Observational cross-sectional serological study in 352 HCPs who worked at São Paulo Hospital - Federal University of São Paulo (UNIFESP) in 2020, approved by UNIFESP Ethics Committee. Data collected included sociodemographics, knowledge about Tdap, and vaccination status. Anti-PT IgG were quantified by ELISA: <10 IU/mL seronegative and ≥ 10-1000 IU/mL seropositive. Titers ≥ 10-50 IU/mL were classified low positivity, indicating no recent B. pertussis infection or Tdap vaccination; >50 IU/mL high positivity, indicating recent B. pertussis infection or Tdap vaccination, and > 100 IU/mL as acute B. pertussis infection or Tdap vaccination in the previous year. Comparisons were done by Chi-square test, multivariable logistic regression, and Pearsons correlation, at 5% p-level. RESULTS: 331/352 HCPs were not aware the Brazilian National Immunization Program recommends Tdap for all HCPs and pregnant women. 68/339 HCPs received Tdap (mean 3.1 ± 2.0 years). 55/352 were seronegative for pertussis, all unvaccinated. 56/271 with no history of Tdap vaccination had high positivity. The probability of anti-PT IgG > 50 IU/mL was 11.5 times higher in Tdap vaccinated HCPs than in non-vaccinated (p < 0.001). There was a weak but significant correlation between anti-PT IgG and interval of Tdap vaccination (r = 0.404; p = 0.001). Anti-PT IgG dropped 5 IU/mL/year (p = 0.001). CONCLUSION: Better education of HCPs on needs and benefits of Tdap vaccination is critical. Goals must be to improve HCPs vaccination coverage.

WEIGHT REGAIN AND THE METABOLIC PROFILE OF WOMEN IN THE POSTOPERATIVE PERIOD OF BARIATRIC SURGERY: A MULTIVARIATE ANALYSIS.

BACKGROUND: Weight regain in the postoperative period after bariatric surgery is directly related to the relapse of preoperative comorbidities and a negative impact on the patients' biochemical profile. AIMS: To assess the metabolic impact of weight regain on preoperative comorbidities and on patients' biochemical profiles, in order to show the impact of the complications on the metabolic outcomes of bariatric surgery. METHODS: A retrospective study was carried out with 75 women in the late postoperative period of bariatric surgery who presented pathological weight regain (≥20% of the maximum weight loss). Data of interest consisted of glycemic, lipid, and inflammatory profile measurements at three different moments of evaluation: preoperative period, at the weight nadir (minimum weight), and after weight regain. A multivariate analysis was performed. RESULTS: The mean age was 46.39±12.09 years. Preoperative body mass index was 40.10±4.11 kg/m2. There was an overall increase of 3.36 points in the mean body mass index between the nadir and after regain: from 26.30±3.9 kg/m2 to 29.66±4.66 kg/m2. The mean time to reach the nadir was 18±7.6 months, with an average percentage of excess weight loss of 91.08±11.8%. The median time for pathological weight regain was 48 months, and the mean regain amongst the sample was 8.85±5.65 kg. There was a significant correlation between pathological weight regain and levels of insulin (r=0.351; p<0.011), C-peptide (r=0.303; p<0.011), C-reactive protein (r=0.402; p<0.001), and vitamin D (r=-0.435; p<0.001), the last two being the most influenced by the percentage of weight regained. CONCLUSIONS: The pathological weight regain in the postoperative period of bariatric surgery results in losses in the patients' metabolic and inflammatory profiles. However, the biochemical benefits are sustained up to the preoperative levels of the parameters analyzed.

Bartter Syndrome-Related Variants Distribution: Brazilian Data and Its Comparison with Worldwide Cohorts.

BACKGROUND: Genetic testing is recommended for accurate diagnosis of Bartter syndrome (BS) and serves as a basis for implementing specific target therapies. However, populations other than Europeans and North Americans are underrepresented in most databases and there are uncertainties in the genotype-phenotype correlation. We studied Brazilian BS patients, an admixed population with diverse ancestry. METHODS: We evaluated the clinical and mutational profile of this cohort and performed a systematic review of BS mutations from worldwide cohorts. RESULTS: Twenty-two patients were included; Gitelman syndrome was diagnosed in 2 siblings with antenatal BS and congenital chloride diarrhea in 1 girl. BS was confirmed in 19 patients: BS type 1 in 1 boy (antenatal BS); BS type 4a in 1 girl and BS type 4b in 1 girl, both of them with antenatal BS and neurosensorial deafness; BS type 3 (CLCNKB mutations): 16 cases. The deletion of the entire CLCNKB (1-20 del) was the most frequent variant. Patients carrying the 1-20 del presented earlier manifestations than those with other CLCNKB-mutations and the presence of homozygous 1-20 del was correlated with progressive chronic kidney disease. The prevalence of the 1-20 del in this BS Brazilian cohort was similar to that of Chinese cohorts and individuals of African and Middle Eastern descent from other cohorts. CONCLUSION: This study expands the genetic spectrum of BS patients with different ethnics, reveals some genotype/phenotype correlations, compares the findings with other cohorts, and provides a systematic review of the literature on the distribution of BS-related variants worldwide.

Clinical and laboratory differences between pediatric hospitalized patients with sickle cell disease infected or not by SARS-CoV-2.

OBJECTIVE: The aim of this study was to identify clinical and complete blood count differences between pediatric hospitalized patients with sickle cell disease infected or not by SARS-CoV-2 and compare the complete blood count of patients with sickle cell disease infected by SARS-CoV-2 before hospitalization and on admission. METHODS: This study was a single-center prospective cohort. Data were collected from medical records of pediatric inpatients with sickle cell disease under 18 years old infected or not with SARS-CoV-2 from the first visit to the hospital until discharge and from the last medical appointment. All patients were tested for SARS-CoV-2 by the real-time reverse transcription polymerase chain reaction. RESULTS: Among 57 pediatric patients with sickle cell disease hospitalized from March to November 2020 in a Brazilian academic hospital, 11 (19.3%) had a positive result for SARS-CoV-2. Patients infected by SARS-CoV-2 had a higher prevalence of comorbidities than the ones who were not infected (63.6 vs. 30.4%; p=0.046). During hospital stay, no clinical or complete blood count differences between groups were found. There was a decrease in eosinophil count on hospital admission in patients with sickle cell disease infected by SARS-CoV-2 (p=0.008). CONCLUSIONS: Pediatric hospitalized patients with sickle cell disease infected by SARS-CoV-2 had more comorbidities and had a decrease in eosinophil count between hospital admission and the last medical appointment.

Bacopa monnieri in Patients with Parkinson's Disease: A Pilot Study.

Bacopa monnieri (L.) Wettst. could be of interest in the control of symptoms of Parkinson's disease, but clinical evidence of its efficacy is lacking. This clinical trial assessed the effects of an extract of B. monnieri on parameters that are related to Parkinson's diseases. Twenty volunteers with Parkinson's disease were recruited for a primary, interventional, controlled, parallel, double-blind clinical study. The volunteers were assigned to treatment with either a commercial B. monnieri extract (225 or 450 mg/day) or placebo. The Parkinson's Disease Quality-of-Life (PDQL) questionnaire was applied, and motor activity was assessed before treatment and 30, 60, and 90 days after treatment with the B. monnieri extract or placebo. Characteristics such as age, body weight, and height were also collected. No differences in parkinsonian and systemic symptoms, emotional function, or social function were observed between. The delta percent (Δ%) showed time-dependent improvements in emotional function with B. monnieri treatment at the daily dose of 450 mg. A strong correlation was found between quality of life and motor outcomes at baseline and 30 days of treatment with B. monnieri, and a moderate correlation for 60 and 90 days of treatment with B. monnieri when compared with baseline time. A moderate correlation was found between motor outcomes and Hoehn and Yahr stages at baseline. Our results suggest that B. monnieri extract can improve emotional function in Parkinson's disease patients, but further clinical trials are needed to confirm this possibility.

Expanding the Phenotype of 8p23.1 Deletion Syndrome: Eight New Cases Resembling the Clinical Spectrum of 22q11.2 Microdeletion.

OBJECTIVE: To report the effectiveness of early molecular diagnosis in the clinical management of rare diseases, presenting 8 patients with 8p23.1DS who have clinical features that overlap the phenotypic spectrum of 22q11.2DS. STUDY DESIGN: This report is part of a previous study that aims to provide a precocious molecular diagnosis of the 22q11.2 deletion syndrome in 118 infants with congenital heart disease. To confirm the clinical diagnosis, patients underwent comparative genomic screening by the multiplex ligation-dependent probe amplification (MLPA) assay with the SALSA MLPA probemix kits P064-B2, P036-E1, P070-B2, P356-A1, and P250- B1. Subsequently, the patients performed the genomic microarray using the Infinium CytoSNP-850K BeadChip to confirm the deletion, determine the breakpoints of the deletion, and search for genomic copy number variations. RESULTS: MLPA performed with 3 different kits revealed the 8p23.1 typical deletion involving the PPP1R3B, MSRA, and GATA4 genes in the 5 patients. The array analysis was performed on these 5 patients and 3 other patients (8 patients) who also had clinical suspicion of 22q11 deletion (8 patients) allowed a precise definition of the breakpoints and excluded other genomic abnormalities. CONCLUSIONS: Cytogenomic screening was efficient in establishing a differential diagnosis and ruling out the presence of other concomitant syndromes. The clinical picture of the 8p23.1 deletion syndrome is challenging; however, cytogenomic tools can provide an exact diagnosis and help to clarify the genotype-phenotype complexity of these patients. Our reports underline the importance of early diagnosis and clinical follow-up of microdeletion syndromes.

Optimizing in vitro growth of basil using LED lights / Otimização crescimento in vitro de manjericão usando lâmpadas LED

Tissue culture is an important technique for assessing the influence of light on plant growth. This study evaluated the in vitro cultivation of Ocimum basilicum cultivars under different light sources. First, an experiment was conducted to evaluate the effect of fluorescent and LED (Light Emitting Diode) light sources (yellow, blue, green, and red) on five basil cultivars (Cinnamon, Grecco a Palla, Italian Large, Limoncino, and Maria Bonita), followed by, another experiment, with two LED lights (Growlux and Blue). In vitro basil plants did not exhibit good growth under yellow lamps. The size of the roots of Cinnamon, Grecco a Palla and Limoncino cultivars under the two light conditions were similar. Moreover, the luminous condition of the Growlux lamps generated a greater quantity of leaves and fresh, and dry weight than blue LED lamps for Cinnamon, Grecco a Palla and Limoncino cultivars. Thus, it was concluded that the Growlux lamps promoted a greater amount of basil biomass.

A cultura de tecidos é uma técnica importante para avaliar a influência da luz no desenvolvimento das plantas. O objetivo deste trabalho foi avaliar o cultivo in vitro de cultivares de Ocimum basilicum sob diferentes fontes de luz. Primeiramente, foi avaliado o efeito de fontes de luz fluorescentes e LEDs (Diodo emissores de luz amarela, azul, verde e vermelha) em cinco cultivares de manjericão (Cinnamon, Grecco a Palla, Italian Large, Limoncino e Maria Bonita); e posteriormente o efeito de duas lâmpadas LED (Growlux e Azul). As lâmpadas amarelas não proporcionaram um bom desenvolvimento das plantas de manjericão in vitro. Verificou-se que o tamanho das raízes e massa fresca nas cultivares Cinnamon, Grecco a Palla e Limoncino nas duas condições luminosas foram semelhantes. A condição luminosa das lâmpadas Growlux promoveu maior número de folhas, massa fresca e seca quando comparada com lâmpadas LED azuis nas cultivares Cinnamon, Grecco a Palla e Limoncino. Assim, concluiu-se que as lâmpadas Growlux promovem uma maior quantidade de biomassa de manjericão.

However, the biochemical benefits are sustained up to the preoperative levels of the parameters analyzed.

RESUMO RACIONAL: Reganho de peso no pós-operatório de cirurgia bariátrica está diretamente relacionado à recidiva das comorbidades pré-operatórias e a um impacto negativo no perfil bioquímico desses pacientes. OBJETIVOS: avaliar o impacto metabólico do reganho de peso nas comorbidades pré-operatórias e no perfil bioquímico desses pacientes, a fim de mostrar o impacto das complicações nos desfechos metabólicos finais da cirurgia bariátrica. MÉTODOS: Estudo retrospectivo que analisou 75 mulheres no pós-operatório tardio de cirurgia bariátrica que apresentaram reganho patológico de peso (=20% do máximo de peso perdido). Foram coletados dados referentes às medidas dos perfis glicêmico, lipídico e inflamatório em três momentos distintos de avaliação: no pré-operatório, no nadir de peso (menor peso) e após o reganho ponderal. Foi realizada uma análise multivariada. RESULTADOS: A idade média foi 46.39±12.09 anos. IMC médio pré-operatório foi 40.10±4.11 kg/m2. Houve um aumento de 3,36 pontos no IMC médio entre o nadir e após reganho: de 26.30±3.9 Kg/m2 para 29.66±4.66 Kg/m2. O tempo médio para atingir o nadir foi de 18±7.6 meses, com uma %PEP de 91.08±11.8%. O tempo médio para o reganho patológico foi de 48 meses, e a média de reganho foi 8.85±5.65 kg. Houve correlação significativa entre o reganho patológico e os níveis de insulina (r=0.351; p<0.011), peptídeo C (r=0.303; p<0.011), proteína C reativa (r=0.402; p<0.001) e vitamina D (r=-0.435; p<0.001), sendo os dois últimos os mais influenciados pela porcentagem de reganho de peso. CONCLUSÕES: O reganho de peso patológico no pós-operatório de cirurgia bariátrica resulta em prejuízos ao perfil metabólico e inflamatório dos pacientes. No entanto, os benefícios bioquímicos perduram em relação aos níveis pré-operatórios dos parâmetros analisados

Visceral Leishmaniasis Revealing Undiagnosed Inborn Errors of Immunity

ABSTRACT Visceral Leishmaniasis (VL) is a potentially fatal disease and may be associated with primary or acquired immunodeficiencies. There are few reports, in the literature, of inborn errors of immunity. Here, we report two cases of VL as a marker of inborn errors of immunity, namely, GATA2 and RAB27A deficiency. Our data suggest that VL patients should be screened for primary immunodeficiency, particularly in cases of VL relapse.

First, an experiment was conducted to evaluate the effect of fluorescent and LED (Light Emitting Diode) light sources (yellow, blue, green, and red) on five basil cultivars (Cinnamon, Grecco a Palla, Italian Large, Limoncino, and Maria Bonita), followed by, another experiment, with two LED lights (Growlux and Blue). In vitro basil plants did not exhibit good growth under yellow lamps. The size of the roots of Cinnamon, Grecco a Palla and Limoncino cultivars under the two light conditions were similar. Moreover, the luminous condition of the Growlux lamps generated a greater quantity of leaves and fresh, and dry weight than blue LED lamps for Cinnamon, Grecco a Palla and Limoncino cultivars. Thus, it was concluded that the Growlux lamps promoted a greater amount of basil biomass.

RESUMO: A cultura de tecidos é uma técnica importante para avaliar a influência da luz no desenvolvimento das plantas. O objetivo deste trabalho foi avaliar o cultivo in vitro de cultivares de Ocimum basilicum sob diferentes fontes de luz. Primeiramente, foi avaliado o efeito de fontes de luz fluorescentes e LEDs (Diodo emissores de luz amarela, azul, verde e vermelha) em cinco cultivares de manjericão (Cinnamon, Grecco a Palla, Italian Large, Limoncino e Maria Bonita); e posteriormente o efeito de duas lâmpadas LED (Growlux e Azul). As lâmpadas amarelas não proporcionaram um bom desenvolvimento das plantas de manjericão in vitro. Verificou-se que o tamanho das raízes e massa fresca nas cultivares Cinnamon, Grecco a Palla e Limoncino nas duas condições luminosas foram semelhantes. A condição luminosa das lâmpadas Growlux promoveu maior número de folhas, massa fresca e seca quando comparada com lâmpadas LED azuis nas cultivares Cinnamon, Grecco a Palla e Limoncino. Assim, concluiu-se que as lâmpadas Growlux promovem uma maior quantidade de biomassa de manjericão.

Efficient Methodology for Detection and Classification of Short-Circuit Faults in Distribution Systems with Distributed Generation.

Fault detection and classification are crucial procedures for electric power distribution systems because they can minimize the occurrence of faults. The methods for fault detection and classification have become more problematic because of the significant expansion of distributed energy resources in distribution systems and the change in their currents due to the action of short-circuiting. In this context, to fill this gap, this study presents a robust methodology for short-circuit fault detection and classification with the insertion of distributed generation units. The proposal methodology progresses in two stages: in the former stage, the detection is based on the continuous analysis of three-phase currents, whose characteristics are extracted through maximal overlap discrete wavelet transform. In the latter stage, the classification is based on three fuzzy inference systems to identify the phases with disturbance. The short-circuit type is identified by counting the shorted phases. The algorithm for short-circuit fault detection and classification is developed in MATLAB programming environment. The methodology is implemented in a modified IEEE 34-bus test system and modeled in ATPDraw with three scenarios with and without distributed generation units and considering the following parameters: fault type (single-phase, two-phase, and three-phase), angle of incidence, fault resistance (high impedance fault and low impedance fault), fault location bus, and distributed generation units (synchronous generators and photovoltaic panels). The accuracy is greater than 94.9% for the detection and classification of short-circuit faults for more than 20,000 simulated cases.

Socioeconomic risk markers of congenital Zika syndrome: a nationwide, registry-based study in Brazil.

While it is well known that socioeconomic markers are associated with a higher risk of arbovirus infections, research on the relationship between socioeconomic factors and congenital Zika syndrome (CZS) remains limited. This study investigates the relationship between socioeconomic risk markers and live births with CZS in Brazil. We conducted a population-based study using data from all registered live births in Brazil (Live Births Information System) linked with the Public Health Event Record from 1 January 2015 to 31 December 2018. We used logistic regression models to estimate the OR and 95% CIs of CZS based on a three-level framework. In an analysis of 11 366 686 live births, of which 3353 had CZS, we observed that live births of self-identified black or mixed race/brown mothers (1.72 (95% CI 1.47 to 2.01) and 1.37 (95% CI 1.24 to 1.51)) were associated with a higher odds of CZS. Live births from single women compared with married women and those from women with less than 12 years of education compared with those with more than 12 years of education also had higher odds of CZS. In addition, live births following fewer prenatal care appointments had increased odds of CZS in the nationwide data. However, in the analyses conducted in the Northeast region (where the microcephaly epidemic started before the link with Zika virus was established and before preventive measures were known or disseminated), no statistical association was found between the number of prenatal care appointments and the odds of CZS. This study shows that live births of the most socially vulnerable women in Brazil had the greatest odds of CZS. This disproportionate distribution of risk places an even greater burden on already socioeconomically disadvantaged groups, and the lifelong disabilities caused by this syndrome may reinforce existing social and health inequalities.

Dengue, Zika, and Chikungunya viral circulation and hospitalization rates in Brazil from 2014 to 2019: An ecological study.

BACKGROUND: In addition to their direct pathogenic effects, arthropod-borne (arboviruses) have been hypothesized to indirectly contribute to hospitalizations and death through decompensation of pre-existing comorbidities. Using nationwide data routinely collected from 1 January 2014 to 31 December 2019 in Brazil, we investigated whether local increases in arbovirus notifications were associated with excess hospitalization. METHODS: We estimated the relative risks for the association between municipality- and state-level increases in arboviral case notifications and age-standardized hospitalization rates (i.e., classified as direct or indirect based on ICD-10 codes) using Bayesian multilevel models with random effects accounting for temporal and geographic correlations. For municipality-level analyses, we excluded municipalities with <200 notifications of a given arbovirus and further adjusted the models for the local Gini Index, Human Development Index, and Family Healthcare Strategy (Estratégia de Saúde da Família) coverage. Models for dengue, Zika, and chikungunya were performed separately. RESULTS: From 2014 to 2019, Brazil registered 7,566,330 confirmed dengue cases, 159,029 confirmed ZIKV cases, and 433,887 confirmed CHIKV cases. Dengue notifications have an endemic and seasonal pattern, with cases present in 5334 of the 5570 (95.8%) Brazilian municipalities and most (69.5%) registered between February and May. Chikungunya notifications followed a similar seasonal pattern to DENV but with a smaller incidence and were restricted to 4390 (78.8%) municipalities. ZIKV was only notified in 2581 (46.3%) municipalities. Increases in dengue and chikungunya notifications were associated with small increases in age-standardized arbovirus-related hospitalizations, but no consistent association was found with all-cause or other specific indirect causes of hospitalization. Zika was associated to increases in hospitalizations by neurological diseases. CONCLUSIONS: Although we found no clear association between increased incidence of the three arboviruses and excess risks of all-cause or indirect hospitalizations at the municipality- and state-levels, follow-up investigations at the individual-level are warranted to define any potential role of acute arbovirus infection in exacerbating risks of hospitalization from underlying conditions.

A supervisão acadêmica no Projeto Mais Médicos pelo Brasil antes e durante a pandemia: o que aprendemos? / Academic supervision in the Mais Médicos pelo Brasil Project before and during the pandemic: what have we learned? / Supervisión académica en el Proyecto Mais Médicos pelo Brasil antes y durante la pandemia: ¿qué hemos aprendido?

A produção do cuidado na atenção primária à saúde demanda um perfil de formação e qualificação permanente de profissionais de saúde que incorporem, a partir de suas práticas, os valores coletivos para a produção de saúde das pessoas e populações. Trata-se aqui do relato de experiência dos tutores acadêmicos do Projeto Mais Médicos pelo Brasil, vinculados à Universidade Estadual de Feira de Santana como instituição supervisora (IS), a partir da reflexão sobre as ofertas pedagógicas e dispositivos de ensino-aprendizagem empregados durante as modalidades de supervisão acadêmica de cunho coletivo, antes e durante a pandemia de covid-19, entre 2018 e 2021. Descrevemos o processo de supervisão acadêmica instituído pela IS e os desdobramentos das práticas de saúde atravessadas pela crise sanitária. Foram levantados temas e estratégias metodológicas adotadas em encontros de supervisão locorregionais e longitudinais, apontando alguns desafios e lições aprendidas para práticas de educação permanente em saúde durante o período analisado. Antes da pandemia, os momentos educativos focavam o aperfeiçoamento de condutas clínicas voltadas para qualificação de práticas no cotidiano da APS, enquanto no primeiro ano da emergência em Saúde Pública, mobilizaram-se em torno da resposta à pandemia da covid-19 naquele nível de atenção. Consideramos que a APS se mostrou como locus de grande relevância ao acolher as demandas já existentes no território de abrangência, mas também no contexto de uma pandemia com consequências imensuráveis na saúde e na vida das pessoas, suas famílias e comunidades, sobretudo em populações mais vulnerabilizadas.

Primary Health Care demands a profile of continuing education and qualification of health professionals who incorporate, in their practices, collective values to produce health of people and populations. This paper is an experience report of the Mais Médicos pelo Brasil Project academic tutors, linked to the Feira de Santana State University as a supervisory institution (IS), based on reflections about the pedagogical offers and teaching-learning resources used during collective academic supervisions before and during the COVID-19 pandemic, between 2018 and 2021. It describes the academic supervision process instituted by IS and the unfoldings of health practices crossed by the health crisis. Themes and methodological strategies adopted in locoregional and longitudinal supervision meetings were surveyed, pointing out some challenges and lessons learned for continuing health education practices during the analyzed period. Before the pandemic, the educational moments focused on improving clinical behaviors aimed at qualifying daily PHC practices, while in the first year of the pandemic, they mobilized around combating it at this level of care. PHC showed itself as a locus of great relevance in meeting the country's pre-existing demands, but also in the context of a pandemic with immeasurable health and life consequences for the people, their families and communities, especially in more vulnerable populations.
