Methotrexate for refractory adult atopic dermatitis leads to alterations in cutaneous IL-31 and IL-31RA expression

Abstract Background: Methotrexate (MTX) is an alternative treatment for patients with moderate/severe atopic dermatitis (AD). Objective: The authors evaluated the effect of MTX on the cutaneous expression of cytokines and chemokines that are involved in the inflammatory response in adult AD patients who received treatment with methotrexate for 24 weeks. Methods: The authors conducted a prospective single-institution cohort study with 12 adults with moderate/severe AD who received oral MTX (15 mg/wk for 24 wks) and 10 non-atopic matched controls. The comparison was made of skin biopsies of lesional and non-lesional skin, pre- and post MTX treatment. The authors analyzed mean epidermal thickness and expression of IL-31, IL-31RA, OSMR, TSLP, Ki67, IL-4 mRNA, IL-6, IL-10, TNF-α, IFN-γ, TARC, and CCL-22. Results: There was a reduction in mean epidermal thickness (p = 0.021), an increase in IL-31RA expression (immunohistochemistry) in the epidermis (p = 0.016) and a decrease in IL-31 gene expression (p = 0.019) on lesional AD skin post-MTX treatment. No significant changes in the cutaneous expression of the other evaluated markers were identified. Study limitations: Small sample size and limited length of follow-up. Conclusions: Treatment with MTX in adults with moderate/severe AD reduced epidermal hyperplasia and changed the cutaneous expression of inflammatory cytokines and receptors that are mainly related to pruritus, including IL-31 and IL-31RA.

Relationship between handgrip strength and body composition and laboratory indicators in diabetic and hypertensive patients / Relação da força de preensão com a composição corporal e indicadores laboratoriais de diabéticos e hipertensos

Introduction: The change in handgrip strength (HGS) is an indicator of the emergence of some chronic diseases, such as diabetes mellitus (DM) and systemic arterial hypertension (SAH). Objective: Analyze the relationship between HGS and body composition and laboratory indicators of diabetic and hypertensive patients assisted in Primary Health Care. Methods: The sample consisted of 185 users of a Basic Health Unit in the city of Santarém, Pará, distributed into two groups: control (CTL) ­ users without a diagnosis of DM and/or SAH (n=66); and DM/SAH (n=119) ­ users with DM or SAH or both diseases. Data collection involved sociodemographic, clinical, anthropometric, biochemical, and HGS information. Data were analyzed using descriptive and inferential statistics, adopting p<0.05. Results: It was noted that low HGS in the DM/SAH group was associated with high values of body mass index, abdominal circumference, fat percentage, fat mass, total cholesterol, and triglycerides and with more factors for metabolic syndrome (p<0.05). The CTL group, in relation to DM/SAH for the same HGS classification, demonstrated significance for lower blood pressure values, body mass index, abdominal circumference, fat percentage, and fat mass, as well as a lower chance of developing metabolic syndrome (p<0.05). Conclusion: According to the study proposal, it is concluded that the evaluation and follow-up of HGS in individuals with chronic diseases, especially DM and SAH, is relevant to monitor body adiposity and dyslipidemia and avoid the aggravation of existing diseases or the emergence of new ones (AU).

Introdução: A alteração na força de preensão (FP) manual é indicador para surgimento de algumas doenças crônicas, como a diabetes mellitus (DM) e hipertensão arterial sistêmica (HAS). Objetivo: Analisar a relação da FP com a composição corporal e indicadores laboratoriais de diabéticos e hipertensos assistidos na Atenção Primária à Saúde. Métodos: A amostra foi composta por 185 usuários de uma Unidade Básica de Saúde na cidade de Santarém, Pará, sendo distribuídos em dois grupos: controle (CTL) ­ usuários sem o diagnóstico para DM e/ou HAS (n=66); e DM/HAS (n=119) ­ usuários com DM ou HAS ou as duas doenças. A coleta de dados envolveu informações sócio-demográficas, clínicas, antropométricas, bioquímicas e FP. Os dados foram analisados por estatística descritiva e inferencial, adotando-se p<0,05. Resultados: Notou-se que a FP baixa no grupo DM/HAS apresentou associação com valores elevados do índice de massa corporal, circunferência abdominal, percentual de gordura, massa gorda, colesterol total, triglicerídeos e com mais fatores para a síndrome metabólica (p<0,05). Já o grupo CTL, em rela-ção do DM/HAS para uma mesma classificação de FP, demonstrou significância para menores valores pressóricos, do índice de massa corporal, da circunferência abdominal, percentual de gordura, massa gorda, bem como menor chance para o desenvolvimento da síndrome metabólica (p<0,05). Conclusão: Conclui-se, conforme a proposta do estudo, que é relevante a avaliação e acompanhamento da FP em indivíduos com doenças crônicas, em especial a DM e a HAS, a fim de monitorar a adiposidade corporal e a dislipidemia, evitando o agravo das doenças instaladas ou o surgimento de novas (AU).

Perfil bioquímico de pessoas com diabetes mellituse hipertensão na atenção primária à saúde / Biochemical profile of people with diabetes mellitusand hypertension in primary health care

Introdução: O diabete mellitus (DM) e a hipertensão arterial sistêmica (HAS) são doenças crônicas não-transmissíveis que se associam a alto risco de mortalidade. Objetivo: Analisar o perfil laboratorial de pessoas com DM e HAS acompanhados na atenção primária à saúde. Método: Estudo descritivo e transversal, com a amostra de 345 pessoas em acompanhamento pelas estratégias de saúde da família pertencentes a duas Unidades Básicas de Saúde da zona urbana do município de Santarém, Pará, Brasil. Os participantes foram divididos em quatro grupos conforme diagnóstico: HAS; DM; ambas (DM-HAS); ou nenhuma (SEM). Foram coletadas informações socioeconômicas e clínicas dos participantes, com posterior coleta de sangue para as variáveis bioquímicas. Para a análise de dados foi realizada a estatística descritiva e inferencial, adotando-se significância de p<0,05. Resultados: Em todos os grupos predominaram participantes do sexo feminino, casados, pardos, com renda até dois salários, com 4-7 anos de estudo, não tabagistas e não estilistas. Em relação ao SEM, o DM se associou com valores alterados para glicose (p<0,0001), HDL-c (p=0,0481), ureia (p=0,0252), creatinina (p=0,0006) e hemoglobina (p=0,0024). Já o DM-HAS se associou com a presença de alteração para glicose (p<0,0001), ureia (p=0,0009), creatinina (p=0,0059) e taxa de filtração glomerular (p=0,0048). Conclusão: Conclui-se, conforme o método proposto, que a presença da DM e/ou HAS são capazes de modificar o perfil bioquímico de maneira negativa, bem como se ressalta a importância do acompanhamento desta pessoa pela atenção primária à saúde, visto que algumas pessoas apresentaram alterações bioquímicas que chamam atenção e não estão em acompanhamento (AU).

Introduction:Diabetes mellitus (DM) and systemic arterial hypertension (SAH) are chronic non-communicable diseases that are associated with a high risk of mortality. Objective: To analyze the laboratory profile of people with DM and SAH followed up in primary health care. Methods: Descriptive and cross-sectional study, with a sample of 345 people being monitored by family health strategies belonging to two Basic Health Units in the urban area of the city of Santarém, Pará, Brazil. Participants were divided into four groups according to their diagnosis: SAH; DM; both (DM-SAH); or neither (NO). Socioeconomic and clinical information was collected from the participants, with subsequent blood collection for biochemical variables. Descriptive and inferential statistics were used for data analysis, adopting a significance of p<0.05. Results: In all groups, female participants, married, brown, with an income of up to two salaries, 4-7 years of schooling, non-smokers, and non-alcoholics predominated. Compared to NO, DM was associated with altered values for glucose (p<0.001), HDL-c (p=0.048), urea (p=0.025), creatinine (p<0.001), and hemoglobin (p=0.002). DM-SAH was associated with the presence of alterations in glucose (p<0.001), urea (p<0.001), creatinine (p=0.005), and glomerular filtration rate (p=0.004). Conclusion: In conclusion, the results using the proposed method indicate that the presence of DM and/or SAH is able to negatively modify the biochemical profile. In addition, the importance of monitoring this population in primary health care was demonstrated, since some people presented potentially worrying biochemical alterations that are not being followed up (AU).

miRNA-143 expression is associated with inflammation and time of exposure to amniotic fluid in experimental gastroschisis

Abstract Objective Gastroschisis (GS) is a congenital anomaly in the abdominal wall with the intestinal loops exiting laterally to the umbilicus. The contact of the loops with Amniotic Fluid (AF) causes an inflammatory process in the exposed part, leading to an extended hospital stay and an increased risk of morbidity due to alterations related to intestinal motility. The authors aimed to evaluate the time of exposure to the AF in the experimental GS and to search for potential biomarkers of intestinal inflammation by measuring microRNAs. Methods Rat fetuses were divided into three groups: a) CONTROL, b) GS reared on day 18 (GS = 18), and c) GS reared on day 19.5 (GS = 19) (term = 22 days). On day 21.5, the fetuses were removed for biometric parameters and biochemical analyses: 1) Biometrics: Body and Intestinal Weight (BW, IW), and intestinal-body weight ratio (IW/BW); 2) Descriptive histopathology and 3) miR-143 quantification by real-time Polymerase Chain Reaction (PCR). Results BW was higher in CONTROL than GS 18 and G19 (p < 0.05). IW, IW/BW, intestinal water, and mRNA-143 were higher in GS 18 and GS 19 than in CONTROL, and GS 18 was higher than GS 19 (p < 0.05). The average of the inflammation score from the intestinal wall with mucosal inflammation and intra-epithelial lymphocytes shows worst in GS 18 and GS 19 vs. CONTROL (p < 0.05). Conclusions The tissue expression of mRNA-143 and the morphological changes in the intestine of GS worsened according to the time of exposure to AF, which could be a possible marker of fetal intestinal damage.

What else in times of COVID-19? The role of minimally invasive autopsy for the differential diagnosis of acute respiratory failure in a case of kala-azar

ABSTRACT Visceral leishmaniasis (VL) is a chronic vector-borne zoonotic disease caused by trypanosomatids, considered endemic in 98 countries, mainly associated with poverty. About 50,000-90,000 cases of VL occur annually worldwide, and Brazil has the second largest number of cases in the world. The clinical picture of VL is fever, hepatosplenomegaly, and pancytopenia, progressing to death in 90% of cases due to secondary infections and multi-organ failure, if left untreated. We describe the case of a 25-year-old female who lived in the metropolitan area of Sao Paulo, who had recently taken touristic trips to several rural areas in Southeastern Brazil and was diagnosed post-mortem. During the hospitalization in a hospital reference for the treatment of COVID-19, the patient developed acute respiratory failure, with chest radiographic changes, and died due to refractory shock. The ultrasound-guided minimally invasive autopsy diagnosed VL (macrophages containing amastigote forms of Leishmania in the spleen, liver and bone marrow), as well as pneumonia and bloodstream infection by gram-negative bacilli.

Microbial biostimulants as alternatives for the rooting of olive tree cuttings

Currently, southern Minas Gerais (MG) state is an important producer of different olive tree (Olea europaea L.) cultivars because, in this region, the plants can differentiate the buds to produce flowers and fruit. To stimulate the rooting of cuttings, the synthetic hormone indole-3-butyric acid (IBA) at a concentration of 3 g L−1 is used commercially. However, few studies have investigated arbuscular mycorrhizal fungi (AMF), isolated or combined with rhizobacteria, as a biotechnological tool to produce hormones that function in the rooting of olive tree cuttings. The aim of this study was to evaluate the capacity of different AMF species (Rhizophagus clarus, Gigaspora rosea, or Acaulospora scrobiculata), combined or not with IBA or rhizobacteria, to promote the rooting of three olive tree cuttings (Arbequina, Grappolo 541, and Maria da Fé) with potential for cultivation in this region. For this, three experiments were conducted at the Experimental Farm of EPAMIG in Maria da Fé (MG), and the rooting potential of the olive tree cuttings inoculated with I) AMF, II) AMF combined with increasing doses of IBA, and III) AMF combined with three isolates of rhizobacteria was evaluated. The inoculation of olive tree cuttings of cultivars Arbequina, Grappolo 541, and Maria da Fé with Rhizophagus clarus, Gigaspora rosea, or Acaulospora scrobiculata combined or not with IBA or rhizobacteria did not significantly promote rooting. Alternative forms of rooting olive tree cuttings are still a challenge, and further studies for standardizing methodologies and experimental conditions are required.

Incidental thyroid carcinoma: Correlation between FNAB cytology and pathological examination in 1093 cases

Abstract Objective To investigate Incidental Thyroid Carcinoma (ITC) by comparing the results of Fine Needle Aspiration Biopsy (FNAB) cytology and the postoperative pathological findings. Methods Data of 1479 patients who underwent total thyroidectomy were retrieved. Three hundred eighty-six patients were excluded due to insufficient data. Each surgical specimen studied received two histopathological diagnoses: the local diagnosis ‒ for the same area in which the FNAB was performed; and the final diagnosis, which includes a study of the entire surgical specimen. Results A thousand and ninety-three patients were investigated. FNAB result was malignant in 187 patients, benign in 204, suspicious or indeterminate in 668 cases, and inconclusive in 34 cases. The prevalence of ITC was 15.1%. Most of the ITC in this series was less than 0.5 cm. The incidence of ITC was higher in Bethesda III (17.5% ITC) and IV (19% ITC) than in Bethesda II cases (1.5% false negatives and 9% ITC). Conclusion Although the incidence of false-negative results in Bethesda II nodules is only 1.5%, 9% of these patients had ITC in the thyroid parenchyma outside the nodule that underwent preoperative FNAB. The incidence of ITC in the same scenario was even higher in Bethesda III (17.5%) and Bethesda IV cases (19%). Ultrasonography-guided FNAB is an excellent method for the assessment of thyroid nodules. However, biopsy sites should be carefully selected. Despite the high incidence of incidentalomas, total thyroidectomy should not always be the treatment of choice due to its rare but potentially serious complications. The findings of the present study can assist future clinical decisions towards active surveillance strategies for the management of papillary thyroid carcinoma.

Avaliação do perfil bioquímico, hematológico e imunológico em pacientes com diagnóstico recente para HIV de um Centro de Referência em Santarém, Pará, Brasil / Evaluation of the biochemical, hematological and immunological profile in patients with a recent diagnosis of HIV in Santarém Reference Center, Pará, Brazil

Introdução: Alterações hematológicas, bioquímicas e imunológicas podem estar presentes no paciente infectado pelo HIV, no momento do diagnóstico, antes ou depois de iniciar com os antirretrovirais. Objetivo: Analisar o perfil bioquímico, hematológico e imunológico de pacientes com diagnóstico recente para HIV. Método: O estudo avaliou 321 prontuários de pacientes recém diagnosticados com a infecção pelo HIV. A coleta de dados envolveu informações sociodemográficas (data de nascimento, idade, sexo, escolaridade, estado civil, vínculo empregatício e procedência), clínicas (data do diagnóstico para a infecção pelo HIV, situação de imunodeficiência e tipo de exposição), bioquímicas (glicose, triglicerídeos, colesterol total e frações), hematológicas (hemoglobina e plaqueta) e imunológicas (linfócitos T CD4+ e carga viral). Os dados foram analisados por estatística descritiva e inferencial, adotando-se p<0,05. Resultados: Notou-se predominância do sexo masculino (67%), faixa etária de 18-27 anos (39,9%), solteiros (58,6%) e com 32% dos pacientes apresentando Aids. Das variáveis analisadas, o sexo masculino apresentou, em relação às mulheres, maior quantidade de hemoglobina e menores valores para contagem de linfócitos T CD4+, glicose e colesterol total (p<0,05). Além disso, ressalta-se que 69% da amostra apresentou alguma alteração lipídica, 96% tinha carga viral detectável e 29% apresentou linfócitos T CD4+ <200 cel/mm3. Conclusão: Pessoas vivendo com o HIV, no momento do diagnóstico, podem apresentar alterações imunológicas, hematológicas e bioquímicas, tornando imprescindível a avaliação, acompanhamento e orientação multiprofissional, tanto antes como posterior introdução dos antirretrovirais, a fim de evitar futuros agravos a saúde.

Introduction: Hematological, biochemical, and immunological alterations may already be present in HIV-infected patients at the time of diagnosis or before, or after starting antiretroviral therapy. Objective: Analyze the biochemical, hematological, and immunological profile of patients with a recent diagnosis of HIV. Method: The study evaluated 321 medical records of patients newly diagnosed with HIV infection. Data collection involved sociodemographic (date of birth, age, gender, education, marital status, employment relationship, and origin), clinical (date of diagnosis for HIV infection, immunodeficiency status, and type of exposure), biochemical (glucose, triglycerides, total cholesterol, and fractions), hematological (hemoglobin and platelet) and immunological (CD4+ T lymphocytes and viral load) information. Data were analyzed by descriptive and inferential statistics, adopting p<0.05. Results: There was a predominance of males (67%), aged 18-27 years (39.9%), single (58.6%), and 32% of patients had AIDS. Of the variables analyzed, males presented higher amounts of hemoglobin and lower values for CD4+ T lymphocyte count, glucose, and total cholesterol in relation to females (p<0.05). In addition, it is noteworthy that 69% of the sample presented a lipid alteration, 96% had a detectable viral load, and 71% had CD4+ T lymphocytes <200 cells/mm3. Conclusion: People living with HIV, at the time of diagnosis, may present immunological, hematological, and biochemical alterations, making multidisciplinary evaluation, follow up, and guidance essential, both before and after the introduction of antiretroviral therapy, in order to avoid future health problems.

Identifying adverse drug events in patients at a pediatric ward in a Brazilian hospital: application and performance of the triggers / Identificação de eventos adversos a medicamentos em pacientes de enfermaria pediátrica em um hospital brasileiro: aplicação e desempenho de rastreadores

Abstract Objectives: to evaluate the performance of a trigger tool in identifying adverse drug events (ADE) in hospitalized children. Methods: a retrospective cohort study review on 133 medical records at a federal maternal and child reference hospital in Rio de Janeiro in 2016. A list of 14 triggers was developed to detect ADE in the pediatric population. Three steps were performed: (1) search for triggers; (2) selection of suspected cases of ADE and (3) final determination of ADE by experts' consensus. Results: 360 triggers were identified in 100 hospitalizations (75.2%), with an average of 2.7 triggers/ hospitalization. The most frequent triggers were "abrupt medication stop" (79.7%); "antiemetics use" (8.9%) and "laxatives use" (7.2%); while the "diphenhydramine use", "phytomenadione use" and "excessive sedation/lethargy/fall/hypotension" obtained the highest performance indicating ADE every time they occurred. Thirty-one ADE were identified in 12.8% of the hospitalizations; 11 (35.5%) ADE were detected without the aid of the triggers thus, pruritus and diarrhea were the most frequent. Conclusion: the trigger tool proved to be useful in identifying ADE in hospitalized children, especially if high performance and high frequency triggers are used in identifying the events. The inclusion of the triggers "diarrhea" and "pruritus", may favor the identification of ADE in patients at pediatric wards.

Resumo Objetivos: avaliar o desempenho de uma ferramenta de rastreamento de eventos adversos a medicamentos (EAM) em crianças hospitalizadas. Métodos: estudo de coorte retrospectivo com revisão de 133 prontuários de hospital federal de referência materno infantil no Rio de Janeiro, em 2016. Uma lista de 14 rastreadores foi usada para detecção de EAM na população pediátrica. Foram realizadas 3 etapas: (1) busca de rastreadores; (2) seleção dos casos suspeitos de EAM e (3) determinação final do EAM por consenso entre especialistas. Resultados: foram identificados 360 rastreadores em 100 internações (75,2%), com média de 2,7 rastreadores/internação. Os rastreadores mais frequentes foram "interrupção abrupta da medicação" (79,7%); "uso de antieméticos" (8,9%) e "uso de laxantes" (7,2%) enquanto que "uso de difenidramina", "uso de fitomenadiona" e "excesso de sedação/letargia/queda/hipotensão" obtiveram o maior rendimento indicando EAM em todas as vezes que ocorreram. Trinta e um EAM foram identificados em 12,8% das internações; 11(35,5%) EAM foram detectados sem auxílio dos rastreadores, sendo prurido e diarreia os mais frequentes. Conclusão: a ferramenta de rastreadores mostrou-se útil para a identificação de EAM em crianças hospitalizadas, principalmente se forem utilizados rastreadores com alto rendimento e alta frequência na identificação de eventos. A inclusão dos rastreadores diarreia e prurido pode favorecer a identificação de EAM em pacientes de enfermaria pediátrica.

Dissecção do plexo cervical na formação médica: aplicabilidades clínicas e cirúrgicas / Dissection of the cervical plexus in medical training: clinical and surgical applicabilities

A Anatomia da região cervical é de particular importância para os clínicos e cirurgiões de diversas especialidades médicas. Em se tratando da organização nervosa presente na região anterolateral do pescoço, encontra-se o plexo cervical, formado pelos ramos anteriores dos nervos cervicais C1 a C4, cuja função é promover a sensibilidade da pele anterolateral cervical, torácica anterossuperior e do couro cabeludo posterior, na cabeça, além de controlar a musculatura infra-hióidea e diafragmática. Logo, lesões a essa estrutura nervosa e aos seus ramos podem causar graves complicações ao corpo humano. Esse trabalho objetivou utilizar a dissecção da região anterolateral do pescoço como uma ferramenta pedagógica para o estudo das relações anatômicas dos nervos do plexo cervical observados durante essa prática, assim como relatar algumas de suas importâncias clínicas e cirúrgicas. O presente estudo é caracterizado como qualitativo/descritivo. A dissecção foi realizada semanalmente, durante o segundo semestre de 2018 e o primeiro semestre de 2019, com a supervisão do professor responsável e auxílio do técnico de laboratório, no Laboratório de aulas práticas da Universidade Estadual de Londrina (UEL). Considera-se que a dissecção da região anterolateral do pescoço permitiu a visualização de diversos nervos cutâneos e musculares do plexo cervical, assim como de alguns de seus ramos e suas relações anatômicas. Também contribuiu para o conhecimento da topografia em que se encontravam tais estruturas e sua organização em camadas. Esse conhecimento anatômico é essencial para a prática médica, tanto clínica quanto cirúrgica.(AU)

The anatomy of the cervical region is of particular importance for surgeons and physicians of different medical specialties. The cervical plexus can be found in the anterolateral region of the neck, formed by the anterior branches of the cervical nerves C1 to C4, whose function is to promote the sensitivity of the cervical anterolateral skin, anterosuperior thoracic skin, and posterior scalp, on the head, in addition to controlling the infrahyoid and diaphragmatic muscles. Therefore, injuries to this nervous structure and its branches may cause serious complications to the human body. This work aimed at using the dissection of the anterolateral neck region as a pedagogical tool for the study of the anatomical relationships of the cervical plexus nerves observed during this practice, as well as to highlight some of its clinical and surgical importance. This is a qualitative/descriptive study. The dissection was performed weekly, during the second semester of 2018 and the first semester of 2019, with the supervision of the professor in charge and the assistance of the laboratory technician at the Laboratory of Practical Classes at the State University of Londrina (UEL). It is considered that the dissection of the anterolateral neck region allowed the visualization of several cutaneous and muscular nerves present in the cervical plexus. It also contributed to the knowledge of the topography in which these structures were found and their organization in layers. This anatomical knowledge is essential for both clinical and surgical medical practice.(AU)

Introdução: Usuários do sistema de saúde com doenças crônicas não transmissíveis devem estar em acompanhamento constante para evitar complicações em seu estado de saúde. Objetivo: Analisar os indicadores laboratoriais de saúde em usuários de uma Unidade Básica de Saúde com e sem o diagnóstico para a diabetes e hipertensão. Métodos: A amostra foi de 231 usuários de uma unidade básica de saúde da cidade de Santarém-PA, maiores de idade, que foram agrupados em pacientes com DM/HAS (DM/HAS; n=144), e sem o diagnóstico para DM/HAS (AUS; n=87). As coletas envolveram informações socioeconômicas, clínicas e laboratoriais. Os dados foram tratados com estatística descritiva e inferencial, adotando-se p<0.05. Resultados: Tanto no DM/HAS como no AUS predominou o sexo feminino, estado civil casado, com vínculo empregatício, cor de pele parda, com 4-7 anos de estudo, renda de 1-2 salários, não tabagistas, não etilista e faixa etária de 38-77 anos. A HAS foi a doença mais presente de forma geral, bem como por sexo. Identificou-se no DM/HAS valores menores para a taxa de filtração glomerular (TFG) e maiores valores para a glicemia, triglicerídeos, colesterol total, LDL-c e não HDL-c. Conclusão: De acordo com a proposta desenvolvida, destaca-se que os usuários com DM/HAS apresentam associação positiva para valores alterados de glicemia, colesterol total, não HDL-c, triglicerídeos, TFG e para a presença da síndrome metabólica e risco cardiovascular moderado/alto.

Introduction: Users of the health system with chronic non-communicable diseases must be constantly monitored to avoid complications in their health status. Objective: Analyze laboratory health indicators in users of a Basic Health Unit with and without a diagnosis for diabetes and hypertension. Methods: The sample consisted of 231 users of a basic health unit in the city of Santarém-PA, all of them of age, grouped into patients with DM/SAH (DM/SAH; n=144), and without the diagnosis for DM/SAH (ABS; n=87). The collections involved socioeconomic, clinical, and laboratory information. The data were treated with descriptive and inferential statistics, adopting p <0.05. Results: In both DM/SAH and ABS groups, there was a predominance of female individuals, married status, employed, brown skin color, with 4-7 years of study, income of 1-2 salaries, non-smokers, non-alcoholic drinkers, and aged between 38-77 years. SAH was the most common disease in general, as well as when analyzing by gender. Lower values for the glomerular filtration rate (GFR) were identified in the DM/SAH and higher values for the glycemia, triglycerides, total cholesterol, LDL-c, and non-HDL-c. Conclusion: According to the proposal of this paper, it is noteworthy that users with DM/SAH have a positive association for altered values of blood glucose, total cholesterol, non-HDL-c, triglycerides, GFR, and for the presence of metabolic syndrome and moderate/high cardiovascular risk.

AIDS in the meeting of the Tapajós and Amazon rivers: deaths in the period 2010-2018 in Santarém, Pará, Brazil / AIDS no encontro dos rios Tapajós e Amazonas: óbitos no período de 2010-2018 em Santarém, Pará, Brasil

INTRODUCTION: The city of Santarém, the regional healthcare center in the western Pará State, lacks studies on the epidemic of the human immunodeficiency virus (HIV), in particular, on the causes of death. OBJECTIVE: To characterize the sociodemographic and clinical profile related to the evolution of HIV infection to death. METHODS: The sample consisted of 94 medical records of patients from a reference center in the city of Santarém-PA, who died between 2010-2018. Data were collected on the sociodemographic profile, immunological and clinical characteristics of the patients. Data were analyzed using descriptive and inferential statistics, adopting p<0.05. RESULTS: Most deaths were male (67%), aged between 15-29 years (39%) and diagnosed between 30-44 years (41%), single (54%), mixed race (91.5%), from Santarém (77%) and with sexual intercourse being the main type of exposure (95.7%). Most patients were not being treated at the moment of death (56.4%), the main cause of death was respiratory failure (5%), in which, these individuals had, at the moment of death, TCD4+ lymphocytes <200 cell/mm3 (26%) and detectable viral load (29%). CONCLUSION: The lifetime from diagnosis to death was 48.45±50,30 months, and immunosuppression in the diagnosis was positively associated with the shortest survival time. However, sex was not associated with the immunological profile, age at the time of diagnosis, and death. There was only a tendency for women towards immunosuppression and detectable viral load.

INTRODUÇÃO: A cidade de Santarém, o polo assistencial da região oeste do Pará, carece de estudos sobre a epidemia do vírus da imunodeficiência humana (HIV), especialmente, sobre as causas de óbitos. OBJETIVO: Caracterizar o perfil sociodemográfico e clínico relacionado à evolução da infecção pelo HIV até a morte. MÉTODO: A amostra foi de 94 prontuários de pacientes de um centro de referência do município de Santarém-PA, que evoluíram a óbito entre os anos de 2010-2018. Foram levantados os dados sobre o perfil sociodemográfico, características imunológicas e clínicas dos pacientes. Os dados foram analisados por estatística descritiva e inferencial, adotando-se p<0,05. RESULTADOS: A maioria dos óbitos foi de indivíduos do sexo masculino (67%), com faixa etária do diagnóstico entre 15-29 anos (39%) e de falecimento entre 30-44 anos (41%), solteiros (54%), pardos (91,5%), procedentes de Santarém (77%) e com a relação sexual sendo o principal tipo de exposição (95,7%). A maioria dos pacientes não estava em tratamento no momento do óbito (56,4%), a principal causa de morte foi por insuficiência respiratória (5%), no qual, esses indivíduos apresentavam, no momento da morte, linfócitos TCD4+ <200 cél/mm3 (26%) e carga viral detectável (29%). CONCLUSÃO: O tempo de vida do diagnóstico ao óbito foi de 48,45±50,30 meses e a presença de imunossupressão no diagnóstico associou-se positivamente com o menor tempo de sobrevida. Contudo, o sexo não apresentou associação com o perfil imunológico, a idade no momento do diagnóstico e do óbito, apenas notou-se uma tendência das mulheres para a imunossupressão e carga viral detectável.

Association between social isolation, level of physical activity and sedentary behavior in pandemic times / Associação de isolamento social, nível de atividade física e comportamento sedentário em tempos pandêmicos / Asociación entre el aislamiento social, el nivel de actividad física y la conducta sedentaria en tiempos de pandemia

Objective: To analyze the association between social isolation (SI), physical activity level (PAL) and sedentary behavior in the university community in pandemic times. Methods: A cross-sectional epidemiological study was carried out from May 7 to June 4, 2020, with 194 participants linked to the Federal University of Jataí Universidade Federal de Jataí ­ UFJ), in Goiás, Brazil. Data were collected using a form created on Google Forms® and sent to the email addresses of the academic community of UFJ to assess socioeconomic characteristics, lifestyle, body composition, physical activity level, and sedentary behavior, taking into account the periods prior to and during SI. Data were analyzed using descriptive and inferential statistics, with p<0.05 considered significant. Results: The study participants were predominantly women (n=141; 72.6%), 18-27 years old (n=100; 71%), single(n=96; 68%), students (n=110; 78%), and had no pre-existing diseases (n=94; 67%). Increases in the body mass and body massindex (BMI) (p<0.05) were observed during SI, and physical activity downtime increased for all participants, regardless of sex(p<0.05). Conclusion: SI recommended by health managers due to the pandemic caused by COVID-19 was responsible for inducing an increase in body mass and BMI accompanied by an increase in screen time during the week, as well as a decrease in the PAL of individuals belonging to the community of university students of UFJ.

Salivary glands are a target for SARS-CoV-2: a source for salivacontamination

The ability of the new coronavirus SARS-CoV-2 to spread and contaminate is one of the determinants of the COVID-19 pandemic status. SARS-CoV-2 has been detected in saliva consistently, with similar sensitivity to that observed innasopharyngeal swabs. We conducted ultrasound-guided postmortem biopsies in COVID-19 fatal cases. Samples ofsalivary glands (SGs; parotid, submandibular, and minor) were obtained. We analyzed samples using RT-qPCR, immu-nohistochemistry, electron microscopy, and histopathological analysis to identify SARS-CoV-2 and elucidate qual-itative and quantitative viral proles in salivary glands. The study included 13 female and 11 male patients, with amean age of 53.12 years (range 8­83 years). RT-qPCR for SARS-CoV-2 was positive in 30 SG samples from18 patients (60% of total SG samples and 75% of all cases). Ultrastructural analyses showed spherical 70­100 nm viral particles, consistent in size and shape with the Coronaviridae family, in the ductal lining cell cytoplasm,acinar cells, and ductal lumen of SGs. There was also degeneration of organelles in infected cells and the presence of acluster of nucleocapsids, which suggests viral replication in SG cells. Qualitative histopathological analysis showedmorphologic alterations in the duct lining epithelium characterized by cytoplasmic and nuclear vacuolization, as wellas nuclear pleomorphism. Acinar cells showed degenerative changes of the zymogen granules and enlarged nuclei.Ductal epithelium and serous acinar cells showed intense expression of ACE2 and TMPRSS receptors. An anti-SARS-CoV-2 antibody was positive in 8 (53%) of the 15 tested cases in duct lining epithelial cells and acinar cellsof major SGs. Only two minor salivary glands were positive for SARS-CoV-2 by immunohistochemistry. Salivaryglands are a reservoir for SARS-CoV-2 and provide a pathophysiological background for studies that indicate theuse of saliva as a diagnostic method for COVID-19 and highlight this biological uid's role in spreading the disease.© 2021 The Pathological Society of Great Britain and Ireland.

An autopsy study of the spectrum of severe COVID-19 in children: From SARS to different phenotypes of MIS-C

Background: COVID-19 in children is usually mild or asymptomatic, but severe and fatal paediatric cases have been described. The pathology of COVID-19 in children is not known; the proposed pathogenesis for severe cases includes immune-mediated mechanisms or the direct effect of SARS-CoV-2 on tissues. We describe the autopsy findings in five cases of paediatric COVID-19 and provide mechanistic insight into the mechanisms involved in the pathogenesis of the disease. Methods: Children and adolescents who died with COVID-19 between March 18 and August 15, 2020 were autopsied with a minimally invasive method. Tissue samples from all vital organs were analysed by histology, electron microscopy (EM), reverse-transcription polymerase chain reaction (RT-PCR) and immunohistochemistry (IHC). Findings: Five patients were included, one male and four female, aged 7 months to 15 years. Two patients had severe diseases before SARS-CoV-2 infection: adrenal carcinoma and Edwards syndrome. Three patients were previously healthy and had multisystem inflammatory syndrome in children (MIS-C) with distinct clinical presentations: myocarditis, colitis, and acute encephalopathy with status epilepticus. Autopsy findings varied amongst patients and included mild to severe COVID-19 pneumonia, pulmonary microthrombosis, cerebral oedema with reactive gliosis, myocarditis, intestinal inflammation, and haemophagocytosis. SARSCoV- 2 was detected in all patients in lungs, heart and kidneys by at least one method (RT-PCR, IHC or EM), and in endothelial cells from heart and brain in two patients with MIS-C (IHC). In addition, we show for the first time the presence of SARS-CoV-2 in the brain tissue of a child with MIS-C with acute encephalopathy, and in the intestinal tissue of a child with acute colitis. Interpretation: SARS-CoV-2 can infect several cell and tissue types in paediatric patients, and the target organ for the...(AU)

Medical students with performance difficulties need wide support: Initial results of an academic tutoring program

BACKGROUND: Even students with previous academic success may face challenges that affect their academic performance. Many medical schools offer programs to students at the risk of academic failure, to ensure that they succeed in the course. OBJECTIVE AND METHODS: In this report we describe a pioneering academic tutoring program developed at a Brazilian medical school and discuss the initial results of the program based on the feedback from tutors and data regarding the progression of students in the medical course. RESULTS: In 2018, 33 students enrolled into the program. Students' performance difficulties were mainly associated with mental health problems and socioeconomic vulnerability. Of the 33 students, 27 (81.8%) were assisted by the Mental Health Support Service and 16 (48.5%) were assisted by the Social Assistance Service. In addition to the planning academic activity class load, tutors were able to assist students in solving socioeconomic issues, carrying out personal support interventions with the promotion of self-esteem, and presenting suggestions for behavioral changes in their routine. For most students (72%), the action plan proposed by the tutors was successful. Eight of the 14 (57%) students in the fourth year progressed to the final two years of in-hospital practical training (internship). CONCLUSIONS: The Academic Tutoring Program showed positive results for most of the students. Close monitoring and tutor intervention allowed students with poor academic performance to overcome the low performance cycle. These important tasks demand time and energy from tutors, and institutional recognition of these professionals is essential for the successful maintenance of the program.

Relative age effect in brazilian handball selections / Efeito relativo da idade nas seleções brasileiras de handebol

ABSTRACT The aim of this study was to evaluate the relative age effect (RAE) in Brazilian male handball teams who competed in the world championships in the U-19, U-21, and adult categories. The sample was composed by 160 male handball players, 47 players being on U-19 category, 48 on U-21, and 65 on Adult category. The chronological age, body mass, height, and game position of each athlete were obtained on the International Federation of Handball website. The adopted significance level was of 5%. RAE was observed in all the three following categories U-19 (X2=21.511, P<0.01), U-21 (X2=15.894, P=0.01) and Adults (X2=35.123, P<0.01). Moreover, no RAE was found in re-selection process by sequential category (P= 0.63, U-19 to U-21; P= 0.46, U-21 to Adult). The RAE is found in Brazilian male handball national teams. However, this effect was not found in re-selection process, thus, players have great influence of RAE in U-19 and this remains through subsequent categories.

RESUMO O objetivo do presente estudo foi avaliar o efeito relativo da idade (ERI) nas seleções Brasileira de handebol que competiram nos campeonatos mundiais das categorias Sub-19, Sub-21 e Adulta. A amostra foi composta por 160 jogadores de handebol do sexo masculino, sendo 47 pertencentes a categoria Sub-19, 48 a Sub-21 e 65 a Adulta. A idade cronológica, massa corporal, estatura e posição de jogo de cada atleta foram obtidas no site oficial da Federação Internacional de Handebol. O nível de significância adotado foi de 5%. ERI foi observado em todas as três seguintes categorias Sub-19 (X2=21.511, P<0.01), Sub-21 (X2=15.894, P=0.01) e adulta (X2=35.123, P<0.01). Além disso, não foi encontrado ERI no processo de re-seleção pela categoria sequencial (P= 0.63, Sub-19 para Sub-21; P=0.46, Sub-21 para Adulta). O ERI foi encontrado nas seleções brasileiras de handebol. Contudo, este efeito não foi encontrado no processo de re-seleção, assim, os jogadores sofrem grande influência do ERI na categoria Sub-19 e isto permanece durante as categorias subsequentes até a equipe adulta.
