Abstract Background: Real-world, primary data on the treatment of psoriasis are scarce, especially concerning the role of soluble biomarkers as outcome predictors. Objective: The authors evaluated the utility of Th1/Th17 serum cytokines along with clinical characteristics as predictors of drug survival in the treatment of psoriasis. Methods: The authors consecutively included participants with moderate to severe psoriasis who were followed up for 6 years. Baseline interferon-α, tumor necrosis factor-α, and inter-leukin (IL)-2, IL-4, IL-6, IL-10, and IL-17A were measured using a cytometric bead array; clinical data were assessed. The authors calculated hazard ratios (HRs) for drug survival using a Cox proportional hazards model. Results: The authors included 262 patients, most of whom used systemic immunosuppressants or biologics. In the multivariate model, poor quality of life measured by the Dermatology Life Quality Index (HR = 1.04; 95% CI 1.01–1.07; p = 0.012) and elevated baseline IL-6 (HR = 1.99; 95% CI 1.29–3.08; p = 0.002) were associated with treatment interruption. Study limitations: The main limitation of any cohort study is the presence of confounders that could not be detected in clinical evaluation. Conclusions: Poor quality of life and elevated baseline serum IL-6 level predicted treatment interruption in patients with moderate to severe psoriasis. Although IL-6 is not the most important mediator of the inflammatory pathway in the skin environment, it is an interesting biomarker candidate for predicting psoriasis treatment response.

Abstract In the modern world, cancer is a growing cause of mortality, but archeological studies have shown that it is not exclusive to modern populations. The aim of this study is to examine the epidemiologic, social, and clinicopathologic features of head and neck cancers in ancient populations. To do this, we extracted all records that described malignant lesions in the head and neck region available in the Cancer Research in Ancient Bodies Database (CRAB). The estimated age, sex, physical condition of the remains (skeletonized, mummified), anatomic location of tumors, geographic location, chronology, tumor type, and methods of tumor diagnosis were collected. One hundred and sixty-seven cases were found, mostly originating from Europe (51.5%). Most records were of adults between 35 and 49 years of age (37.7%). The most involved site was the skullcap (60.4%), and the most common malignancies were metastases to the bone (65.3%) and multiple myeloma (17.4%). No primary soft tissue malignancies were registered. The results of our study indicate that head and neck cancers were present in ancient civilizations, at least since 500,000 BCE. The available data can help to improve the current understanding of the global distribution of head and neck cancer and its multidimensional impacts on populations in the contemporary world.

ABSTRACT Introduction: Chronic kidney disease patients have a higher risk of infection and worse clinical outcomes after coronavirus disease. We aimed to assess the prevalence of infection and the humoral response after vaccination in peritoneal dialysis patients. Methods: Three types of vaccines were administered (two doses) with the antibody detection at least six months after. Coronavirus disease 2019 infections, hospital admissions, and deaths were evaluated. Results: From 70 prevalent patients, 45 were included. There was a significant increase in antibody level, with a median of 92 (36, 447) U/mL. Only 4% of patients remained seronegative. History of immunosuppressive therapy was associated with no response (100% vs 60%, p=0.010). There were two infections after the vaccination, without hospital admission. Conclusion: Immunization against coronavirus disease was effective in generating a humoral response in peritoneal dialysis patients. There was also an evident impact of immunosuppressive therapy on vaccine response in peritoneal dialysis patients.

ABSTRACT Background: Children presenting enuresis are more likely to be asthmatics. The association between enuresis and sleep-disordered breathing has already been demonstrated and several studies have shown at least partial improvement of two thirds or more of the cases of enuresis adenoidectomy. Studies have already described associations between enuresis and allergies but do not assess the repercussions of allergy treatment in enuretics. Objective: This study aims to evaluated whether asthma treatment alters the course of enuresis and whether there is any predictive factor associated with this improvement. Materials and Methods: Twenty patients (5 - 12 years old) with uncontrolled enuresis and asthma, received treatment for asthma. Children were also assessed for the presence of rhinitis and other allergies. The control of asthma was confirmed by a validated questionnaire and primary enuresis by clinical history and wet night diaries. Patients received only asthma treatment. Results: At least partial improvement of enuresis was observed in 55% of the patients with an increase in 64.4% in the number of dry nights at the end of the study (p=0.01). The “presence of other allergies” and “obstruction seen in nasal endoscopy” positively influenced the improvement of urinary symptoms (OR = 3.350; CI 0.844–13.306) and (OR=1.272; CI 0.480-3.370), respectively. Discussion: Until now, only patients presenting upper airway obstruction were known to benefit from the improvement of urinary symptoms when undergoing treatment for their respiratory problems. In our study, we found at least partial improvement in enuresis in 55% of our patients, with only clinical asthma treatment. Conclusion: Controlling asthma in children with primary enuresis resulted in a significant increase in dry nights.

Abstract The present study aims to describe the epidemiological profile American Integumentary Leishmaniasis (LTA)and Visceral Leishmaniasis (LV) in the Montes Claros/MG population between 2016 to 2020. The study is based on documentary research adopting a quantitative. The data was gathered from the electronic Notifiable Diseases Information System (SINAN - Sistema de Informações de Agravos de Notificação. Results showed that 457 notifications were registered, 328 cases of ATL, and 129 cases of VL. The profile of the public affected by both diseases was mainly male, aged between 20 to 59 years, who have incomplete elementary education and declared to be brown. The data allows concluding that ATL constantly increases cases, whereas VL has been reducing its incidence. Thus, it is necessary to strengthen and expand the disease control policies since it is a historically endemic region with a high number of cases in recent years.

Resumo O objetivo deste estudo é descrever o perfil epidemiológico da Leishmaniose Tegumentar Americana (LTA) e da Leishmaniose Visceral (LV) na população do município de Montes Claros/MG no período de 2016 a 2020. Quanto ao método, trata-se de um estudo com base em recolha documental e quantitativo realizado a partir do banco de dados eletrônico do Sistema de Informações de Agravos de Notificação (SINAN). Os principais resultados evidenciaram registradas 457 notificações, sendo 328 casos de LTA e 129 casos de LV. O perfil do público acometido em ambas as doenças foi principalmente do sexo masculino, faixa etária de 20 a 59 anos, que possuem ensino fundamental incompleto e declaradas pardas. Os dados permitem concluir que a LTA apresenta um constante aumento no número de casos, mas a LV vem reduzindo a sua incidência. Assim, torna-se necessário reforçar e ampliar as políticas de controle da doença uma vez que se trata de uma região historicamente endêmica e que vem apresentando elevado número de casos nos últimos anos.

Abstract Due to the public health impact that Covid-19 has caused worldwide and reinforcing the need to develop research aimed at pediatric patients affected by Covid-19, this study aimed to identify the epidemiological profile of suspected cases of Covid-19 in children hospitalized in a university hospital in Minas Gerais. This is an epidemiological, descriptive, cross-sectional study carried out in the pediatrics department of a university hospital in Minas Gerais, Brazil. The data was collected between the period from July 2020 to December 2021. For data collection, a spreadsheet containing data related to the variables was used: sex, age, race, clinical manifestation, pre-existing condition, use of oxygen therapy, mean length of stay, and mortality rate. Data were organized into tables and analyzed based on absolute frequencies and percentages. Of the 268 children, 14 (5.22%) were diagnosed with SARS-CoV-2 virus antigens. It is possible to conclude that there was a higher prevalence of the age group 0 to 2 years (53.36%), males (57.47%), and mixed race/color (68.65%). The main clinical manifestations presented were respiratory, fever, and gastrointestinal symptoms. They had an average hospital stay of 6.5 days. It was found that 20.52% had some pre-existing condition, and 58.12% used some oxygen therapy. The production of data on Covid-19 in a hospitalized pediatric population may contribute to a better understanding of the disease and an effective and practical observation for a better understanding by health professionals, aiming at early diagnosis, adequate treatment, and knowledge of essential aspects of the disease.

Abstract Background Sjogren-Larsson syndrome (SLS) is a neurocutaneous disease with an autosomal recessive inheritance, caused by mutations in the gene that encodes fatty aldehyde dehydrogenase (ALDH3A2), clinically characterized by ichthyosis, spastic diplegia, and cognitive impairment. Brain imaging plays an essential role in the diagnosis, demonstrating a nonspecific leukoencephalopathy. Data regarding brain atrophy and grey matter involvement is scarce and discordant. Objective We performed a volumetric analysis of the brain of two siblings with SLS with the aim of detecting deep grey matter nuclei, cerebellar grey matter, and brainstem volume reduction in these patients. Methods Volume data obtained from the brain magnetic resonance imaging (MRI) of the two patients using an automated segmentation software (Freesurfer) was compared with the volumes of a healthy control group. Results Statistically significant volume reduction was found in the cerebellum cortex, the brainstem, the thalamus, and the pallidum nuclei. Conclusion Volume reduction in grey matter leads to the hypothesis that SLS is not a pure leukoencephalopathy. Grey matter structures affected in the present study suggest a dysfunction more prominent in the thalamic motor pathways.

Resumo Antecedentes A Síndrome de Sjogren-Larsson (SSL) é uma doença neurocutânea de herança autossômica recessiva, causada por mutações no gene que codifica a aldeído graxo desidrogenase (ALDH3A2), caracterizada clinicamente por ictiose, diplegia espástica e comprometimento cognitivo. A imagiologia cerebral desempenha um papel essencial no diagnóstico, demonstrando uma leucoencefalopatia inespecífica. Dados sobre atrofia cerebral e envolvimento da substância cinzenta são escassos e discordantes. Objetivo Realizamos uma análise volumétrica do cérebro de dois irmãos com SLS com o objetivo de detectar núcleos profundos de substância cinzenta, substância cerebral cinzenta e redução do volume do tronco encefálico nestes pacientes. Métodos Os dados de volume obtidos da ressonância magnética (RM) cerebral dos dois pacientes usando um software de segmentação automática (Freesurfer) foram comparados com os volumes de um grupo controle saudável. Resultados Redução de volume estatisticamente significativa foi encontrada no córtex do cerebelo, no tronco cerebral, no tálamo e nos núcleos pálidos. Conclusão A redução do volume da substância cinzenta leva à hipótese de que a SSL não é uma leucoencefalopatia pura. As estruturas da substância cinzenta afetadas no presente estudo sugerem uma disfunção mais proeminente nas vias motoras talâmicas.

Resumo Foram analisadas tendências da mortalidade prematura por doenças crônicas não transmissíveis (DCNT) entre 1990 e 2019, as projeções até 2030 e os fatores de risco atribuíveis a estas doenças na Comunidade dos Países de Língua Portuguesa (CPLP). Utilizou-se estimativas do estudo Carga Global de Doenças e análise da carga de mortalidade prematura por DCNT para nove países da CPLP, utilizando taxas padronizadas por idade, usando-se RStudio. Portugal, Brasil, Guiné Equatorial, Angola e Guiné Bissau apresentam taxas de mortalidade prematura por DCNT em declínio e; Timor Leste, Cabo Verde, São Tomé e Príncipe e Moçambique apresentaram aumento das taxas. As projeções indicam que nenhum dos países deverá atingir as metas de redução em um terço da mortalidade prematura por DCNT até 2030. A carga de doença atribuível mostrou que os fatores de riscos mais importantes em 2019 foram: pressão arterial sistólica elevada, tabaco, riscos dietéticos, índice de massa corporal elevado e poluição do ar. Conclui-se pelas profundas diferenças na carga de DCNT entre os países, com melhores resultados em Portugal e Brasil e que nenhum país do CPLP deverá atingir a meta de redução das DCNT até 2030.

Abstract The present study analyzed trends in premature mortality from Noncommunicable diseases (NCDs) between 1990 and 2019, the projections up to 2030, and the risk factors (RFs) attributable to these diseases in the Community of Portuguese Language Countries (CPLP). Estimates from the Global Burden of Disease (GBD) study and the analysis of the burden of premature mortality due to NCDs were used for nine CPLP countries, applying age-standardized rates, using RStudio. Portugal, Brazil, Equatorial Guinea, Angola, and Guinea Bissau showed declining premature mortality rates caused by NCDs, while East Timor, Cape Verde, São Tomé and Príncipe, and Mozambique showed an increase in rates. Projections indicate that none of the countries is expected to achieve the goals of reducing premature mortality due to NCDs by one third by 2030. The attributable burden of disease showed that the most important RFs in 2019 were: high systolic blood pressure (SBP), tobacco, dietary risks, high body mass index (BMI), and air pollution. It can therefore be concluded that there are profound differences in the burden of NCDs among the countries, with better results in Portugal and Brazil, and that no CPLP country is likely to reach the NCD reduction target by 2030.

ABSTRACT. This study aimed to map the world's scientific production of bacterial and fungal microbiota in mollusks. The research was carried out in the Web of Science database, using “Fungi AND Mollusk” and “Bacteria AND Mollusk” descriptors and publication time between 2001 and 2021. Indexes were built by years, countries, research areas, and two maps of the co-occurrence of terms. There was a progressive increase in the production of microbiota in mollusks, with more research on bacteria during the investigated period. China and USA were the countries with the highest percentage of publications. Research with fungi and bacteria accounted for 28.41 and 17.66% in China, respectively. While the USA, the percentage was 21.05% for fungi and 16.02% for bacteria. Areas such as marine and freshwater biology (24.77%), fisheries (23.86%), biochemistry and molecular biology (18.60%), and pharmacy (17.83%) showed a higher percentage of indexed articles. There was also a high concentration of deposits of publications in the immunology area for both themes. The groups formed for bacteria and fungi indicated that studies had described the immune responses of mollusks, the genetic aspects associated with their defense mechanisms, pathogen virulence factors, and symbiotic and pathogenic microbiota, highlighting genera Vibrio, Aspergillus, and Escherichia coli pathogenic pathotypes. The bacterial and fungal microbiota in mollusks have been studied in several areas of knowledge and have given rise to research that can support the proper management of mollusks, application in the pharmaceutical industry, and implementation of measures in public health.

Abstract Introduction: cystic fibrosis is a disease that causes inflammation, oxidative stress and metabolic changes that lead to nutrient deficiency, such as vitamin D deficiency. On the other hand, it is suggested that vitamin D has anti-inflammatory and antioxidant actions. Objective: to evaluate the prevalence of hypovitaminosis D and the association between serum 25 hydroxyvitamin D levels with markers of oxidative stress and inflammation in patients with cystic fibrosis. Method: a cross-sectional study was carried out with 48 patients with cystic fibrosis including children, adolescents and adults in the northeast region of Brazil. Blood collection was performed for analysis of 25-hydroxyvitamin D, calcium, parathyroid hormone, inflammatory process (C-reactive protein [CRP] and alpha-1-acid glycoprotein-A1 [A1GPA]) and oxidative stress (malondialdehyde (MDA) and total antioxidant capacity [CAOT]). The statistical analysis was performed using the "Statistical Package for the Social Sciences", adopting a significance level of p < 0.05. Results: vitamin D insufficiency/deficiency was found in 64.6 % of patients. After multiple linear regression analysis, MDA showed an inverse association with blood values of 25-hydroxyvitamin D (p < 0.05) conditioned by the presence of inflammatory process markers. When only oxidative stress was evaluated, this association disappeared. Conclusion: in conclusion, there was a high prevalence of hypovitaminosis D, with 25(OH)D levels associated with greater oxidative stress when combined with inflammatory markers. Improved vitamin D levels may be an alternative to reduce the damage caused by excess oxidative stress and inflammation in CF patients.

Resumen Introducción: la fibrosis quística es una enfermedad que cursa con inflamación, estrés oxidativo y cambios metabólicos que conducen a deficiencia de nutrientes como la vitamina D. Por otro lado, se sugiere que la vitamina D tiene acción antiinflamatoria y antioxidante. Objetivo: evaluar la prevalencia de hipovitaminosis D y la asociación entre los niveles séricos de 25 hidroxivitamina D con los marcadores de estrés oxidativo e inflamación en pacientes con fibrosis quística. Método: estudio transversal realizado con 48 pacientes con fibrosis quística, niños, adolescentes y adultos, de la región nordeste de Brasil. Se realizó una extracción de sangre para el análisis de 25-hidroxivitamina D, calcio, hormona paratiroidea, proceso inflamatorio (proteína C-reactiva [PCR] y alfa-1-glucoproteína ácida-A1 [A1GPA]) y estrés oxidativo (malondialdehído [MDA] y capacidad antioxidante total [CAOT]). El análisis estadístico se realizó utilizando el "Paquete Estadístico para las Ciencias Sociales", adoptando un nivel de significancia de p < 0,05. Resultados: se encontró insuficiencia/deficiencia de vitamina D en el 64,6 % de los pacientes. Después de un análisis de regresión lineal múltiple, la MDA mostró una asociación inversa con los valores sanguíneos de 25-hidroxivitamina D (p < 0,05) condicionado a la presencia de marcadores de proceso inflamatorio; cuando solo se evalúa el estrés oxidativo, esta asociación desaparece. Conclusión: en conclusión, hubo una alta prevalencia de hipovitaminosis D, con niveles de 25(OH)D asociados a mayor estrés oxidativo cuando se combina con marcadores inflamatorios. La mejora de los niveles de vitamina D puede ser una alternativa para reducir el daño causado por el exceso de estrés oxidativo y la inflamación en pacientes con FQ.

Objective: to estimate the reference intervals (RIs) of complete blood count parameters in the Brazilian adult population. Methods: Cross-sectional study, with data from the National Health Survey (PNS), between 2014-2015. The final sample consisted of 2,803 adults. The final sample consisted of 2,803 adults. To establish the RI, exclusion criteria were applied, outliers were removed and partitions were made by sex, age and race/skin color. The non-parametric method was adopted. Differences were assessed using the Mann Withney and Kruskal Wallis tests (p≤0.05). Results: There were statistically significant differences for the following hematological parameters based on sex, red blood cells, hemoglobin, hematocrit, MCH, MCHC, eosinophils and absolute monocytes, neutrophils and platelets (p≤0.05). When analyzed by age, the RIs were statistically different in females for hematocrit, MCV, white blood cells and RDW and in males for red blood cells, white blood cells, eosinophils, mean platelet volume, MCV, RDW and MCH(p≤0.05). For race/color there were differences in the RIs for parameters of hemoglobin, MCH, MCHC, white blood cells and mean platelet volume, neutrophils and absolute eosinophils (p ≤ 0.05). Conclusion: The differences found in the RIs of some in blood count parameters in Brazilian adults reaffirm the importance of having their own laboratory reference standards. The results can support a more accurate interpretation of tests, adequate identification and disease prevention in Brazil.

ABSTRACT Over the past decade, the business of producing juice from grapes (Vitis labrusca L. and hybrids) has been expanding in response to increasing consumption encouraged by campaigns promoting the benefits grape juice can have on health. This study aimed to determine the effect of the production cycle, vine training system, and rootstock on the yield and physical and physical-chemical characteristics of ‘BRS Magna’ grapes grown in the Vale do Submédio São Francisco in the northeastern region of Brazil. The study was conducted in Petrolina, Pernambuco, over eight production cycles (2017 to 2020). The grapevines were trained in three vine training trellis systems: espalier, lyre, and pergola; and grafted onto two rootstocks: IAC 572 and IAC 766. The production cycle, training system, and rootstocks affected the yield components, vigor, and physical characteristics of the BRS Magna grapes. The combination of the pergola training system and rootstock IAC 766 stood out from the others, providing mean yields estimated at 26 t ha –1 per production cycle. The soluble solids content (SS), titratable acidity (TA), and SS TA –1 ratio were affected neither by the training system nor the rootstock, and higher values for SS and lower values for TA were obtained in the first, second, fourth and eighth production cycles. Thus, the pergola training system and rootstock IAC 766 are recommended for promoting yield gains in the ‘BRS Magna’ grape in the Vale do Submédio São Francisco.
