Comparing the Effectiveness and Safety of Dexamethasone, Methylprednisolone and Betamethasone in Lumbar Transforaminal Epidural Steroid Injections.

BACKGROUND: Particulate steroids are thought to exert their effects for long durations at injection sites. However, these types of steroids carry higher risks when used in epidural steroid injections. Catastrophic spinal cord complications, including sudden-onset paraplegia, have been reported due to intravascular particulate steroid preparations that cause embolisms and occlusion of blood vessels, resulting in spinal cord infarctions. Clinicians, therefore, recommend nonparticulate steroids to mitigate these adverse events. To our knowledge, this is the first retrospective study that addresses the effectiveness and safety of methylprednisolone, dexamethasone, and betamethasone when used in transforaminal epidural steroid injections (TFESIs) for the treatment of lumbar radiculopathy. OBJECTIVES: The primary goal of this study was to compare the proportion of patients who received injections of particulate steroids and required zero repeat injections within 12 months of their initial injection to the proportion of patients who received injections of nonparticulate steroids and also required zero repeat injections, as well as to compare the number of patients in the particulate cohort who required one or more repeat injections within 12 months of their initial injection to the number of patients in the nonparticulate cohort who required the same. The secondary goal was to evaluate the proportion of patients ultimately requiring surgery. STUDY DESIGN: This is a single-center, IRB-approved, retrospective study evaluating the safety and effectiveness of nonparticulate as compared to particulate steroid medications when used in TFESIs as minimally invasive treatments for chronic lumbar radiculopathy. SETTING: This study captured data (n = 1717) over a 4-year time frame (01/15/2018 to 01/15/2022). METHODS: The following data were collected from each patient's chart: age, gender, BMI, race, date of initial injection, number of repeat injections at the same lumbosacral level and on the same side within 12 months of the initial injection, and lumbar surgery date (if applicable). Inclusion criteria included: 1) having chronic low back pain of radicular etiology; 2) being at least 18 years old; 3) having experienced the failure of conservative therapy after 12 weeks (including physical therapy and/or medications); 4) having positive physical exam findings supporting nerve impingement (straight leg raise, slump test); and 5) showing lumbar MRI evidence of nerve impingement from disc herniation. Exclusion criteria included: 1) having received prior lumbar surgery at any level (L1-S1); 2) having been given prior TFESIs fewer than 6 months prior to initial injection; 3) having contracted a systemic infection at the proposed injection site; 4) undergoing active cancer treatment; and 5) having gotten any other spine injections. RESULTS: A significantly greater proportion of patients in the nonparticulate steroid cohort received 0 repeat injections (87.5% vs 71.4%, P < 0.001). The particulate steroid cohort demonstrated a significantly greater proportion of patients who received repeat injections within 12 months after the initial injections (12.5% vs 29.6%, P < 0.001). There were no significant differences among patients requiring surgery between the 2 cohorts. Other outcome measures included the identification of risk factors significantly associated with repeat injections. There was a statistically significant weak positive correlation between age and repeat injections (Pearson corr = 0.102; P < 0.001) and a weak negative correlation between ethnicity/race and repeat injections (point-biserial corr = -0.093; P < 0.001).  No adverse events were reported. LIMITATIONS: Not all clinicians included in this study used each of the 3 steroid types, and all clinicians used either particulate or nonparticulate steroids exclusively. CONCLUSIONS: Our study demonstrates that the clinical outcomes associated with TFESIs of nonparticulate steroids are superior to those associated with TFESIs of particulate steroids when either variety of medication is used to treat lumbar radiculopathy. This is the first study to include a clinically useful predictive model using information on laterality, age, and steroid type.

Electrical neuromodulation for the treatment of chronic pain: derivation of the intrinsic barriers, outcomes and considerations of the sustainability of implantable spinal cord stimulation therapies.

INTRODUCTION: For over 60 years, spinal cord stimulation has endured as a therapy through innovation and novel developments. Current practice of neuromodulation requires proper patient selection, risk mitigation and use of innovation. However, there are tangible and intangible challenges in physiology, clinical science and within society. AREAS COVERED: We provide a narrative discussion regarding novel topics in the field especially over the last decade. We highlight the challenges in the patient care setting including selection, as well as economic and socioeconomic challenges. Physician training challenges in neuromodulation is explored as well as other factors related to the use of neuromodulation such as novel indications and economics. We also discuss the concepts of technology and healthcare data. EXPERT OPINION: Patient safety and durable outcomes are the mainstay goal for neuromodulation. Substantial work is needed to assimilate data for larger and more relevant studies reflecting a population. Big data and global interconnectivity efforts provide substantial opportunity to reinvent our scientific approach, data analysis and its management to maximize outcomes and minimize risk. As improvements in data analysis become the standard of innovation and physician training meets demand, we expect to see an expansion of novel indications and its use in broader cohorts.

Application of the iPLUS non-coding sequence in improving biopharmaceuticals production.

The biotechnological landscape has witnessed significant growth in biological therapeutics particularly in the field of recombinant protein production. Here we investigate the function of 3'UTR cis-regulatory elements in increasing mRNA and protein levels in different biological therapeutics and model systems, spanning from monoclonal antibodies to mRNA vaccines. We explore the regulatory function of iPLUS - a universal sequence capable of consistently augmenting recombinant protein levels. By incorporating iPLUS in a vector to express a monoclonal antibody used in immunotherapy, in a mammalian cell line used by the industry (ExpiCHO), trastuzumab production increases by 2-fold. As yeast Pichia pastoris is widely used in the manufacture of industrial enzymes and pharmaceuticals, we then used iPLUS in tandem (3x) and iPLUSv2 (a variant of iPLUS) to provide proof-of-concept data that it increases the production of a reporter protein more than 100-fold. As iPLUS functions by also increasing mRNA levels, we hypothesize that these sequences could be used as an asset in the mRNA vaccine industry. In fact, by including iPLUSv2 downstream of Spike we were able to double its production. Moreover, the same effect was observed when we introduced iPLUSv2 downstream of MAGEC2, a tumor-specific antigen tested for cancer mRNA vaccines. Taken together, our study provides data (TLR4) showing that iPLUS may be used as a valuable asset in a variety of systems used by the biotech and biopharmaceutical industry. Our results underscore the critical role of non-coding sequences in controlling gene expression, offering a promising avenue to accelerate, enhance, and cost-effectively optimize biopharmaceutical production processes.

Awareness of the diagnosis, treatment, and control of diabetes mellitus in Brazil.

OBJECTIVE: To estimate the proportions of awareness, treatment, and control of diabetes mellitus (DM) in the Brazilian adult population. METHOD: This is a cross-sectional study, with data from a representative sample of the Brazilian population, taken from the National Health Survey(PNS 2014/2015). Outcomes were defined based on glycated hemoglobin (HbA1c) measurements, self-reported DM diagnosis, and use of hypoglycemic agents or insulin. The proportion of DM awareness, treatment, and control was estimated according to sociodemographic characteristics, health conditions, and access to health services, and their respective 95% confidence intervals. RESULTS: DM prevalence in the Brazilian population was of 8.6% (95%CI: 7.8-9.3): 68.2% (95%CI: 63.9-72.3) were aware of their diagnosis, 92.2% (95%CI: 88.6-94.7) of those who were aware were undergoing drug treatments, and, of these, 35.8% (95%CI: 30.5-41.6) had controlled HbA1c levels. The proportions of DM awareness, control, and treatment were lower in men aged 18 to 39 years, individuals with low education, without health insurance, and beneficiaries of the Bolsa Família program. CONCLUSION: Approximately one in ten Brazilians has DM. A little more than half of this population is aware of their diagnosis, a condition measured by HbA1c dosage and clinical diagnosis. Among those who know, the vast majority are undergoing drug treatments. However, less than half of these have their HbA1c levels controlled. Worse scenarios were found in subgroups with high social vulnerability.

Investigation of cancer incidence in ELSA-Brasil.

Low- and middle-income countries have high cancer-related mortality rates, and Brazil has one of the highest incidences of all cancers in South America. Since 2008, the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) follows up 15,105 civil adult servants of college education and research institutions in six Brazilian capitals, collecting relevant information on risk factors for the incidence of cancer and other noncommunicable diseases. This study aimed to describe the methodology for surveillance and investigation of the incidence of primary cancers in ELSA-Brasil. The surveillance and investigation involve annual telephone interviews, data collection of medical registries (biopsy records, chemotherapy/radiotherapy reports, hospital records or death certificates/autopsy statements), eligibility and final classification, date and basis of diagnosis, tumor topography and histological type. The cumulative incidence of all types of cancer in ELSA-Brasil during the first five years of follow-up (2009-2013) was 2.27 %. The challenges encountered in the investigation process are related to the lack of data on the occurrence of distant metastasis and essential details regarding diagnoses. However, the quality control and the adequacy of the methods adopted enables the construction of a solid and pioneering database in the country, which will contribute to advance in research on the natural history of the most frequent types of cancer.

Pro-inflammatory polarization and colorectal cancer modulate alternative and intronic polyadenylation in primary human macrophages.

Introduction: Macrophages are essential cells of the immune system that alter their inflammatory profile depending on their microenvironment. Alternative polyadenylation in the 3'UTR (3'UTR-APA) and intronic polyadenylation (IPA) are mechanisms that modulate gene expression, particularly in cancer and activated immune cells. Yet, how polarization and colorectal cancer (CRC) cells affect 3'UTR-APA and IPA in primary human macrophages was unclear. Methods: In this study, we isolated primary human monocytes from healthy donors, differentiated and polarized them into a pro-inflammatory state and performed indirect co-cultures with CRC cells. ChrRNA-Seq and 3'RNA-Seq was performed to quantify gene expression and characterize new 3'UTR-APA and IPA mRNA isoforms. Results: Our results show that polarization of human macrophages from naïve to a pro-inflammatory state causes a marked increase of proximal polyA site selection in the 3'UTR and IPA events in genes relevant to macrophage functions. Additionally, we found a negative correlation between differential gene expression and IPA during pro-inflammatory polarization of primary human macrophages. As macrophages are abundant immune cells in the CRC microenvironment that either promote or abrogate cancer progression, we investigated how indirect exposure to CRC cells affects macrophage gene expression and 3'UTR-APA and IPA events. Co-culture with CRC cells alters the inflammatory phenotype of macrophages, increases the expression of pro-tumoral genes and induces 3'UTR-APA alterations. Notably, some of these gene expression differences were also found in tumor-associated macrophages of CRC patients, indicating that they are physiologically relevant. Upon macrophage pro-inflammatory polarization, SRSF12 is the pre-mRNA processing gene that is most upregulated. After SRSF12 knockdown in M1 macrophages there is a global downregulation of gene expression, in particular in genes involved in gene expression regulation and in immune responses. Discussion: Our results reveal new 3'UTR-APA and IPA mRNA isoforms produced during pro-inflammatory polarization of primary human macrophages and CRC co-culture that may be used in the future as diagnostic or therapeutic tools. Furthermore, our results highlight a function for SRSF12 in pro-inflammatory macrophages, key cells in the tumor response.

Influence of the COVID-19 pandemic on labor and childbirth care practices in Brazil: a cross-sectional study.

BACKGROUND: It has been hypothesized that the coronavirus disease 2019 (COVID-19) pandemic may have changed the conduct of obstetric practices at the time of labor, delivery, and birth. In Brazil, many practices lacking scientific evidence are implemented in this care, which is charcaterized by excessive use of unnecessary interventions. This scenario may have been worsened by the pandemic. Thus, we analyzed the effects of the pandemic on care during prenatal care and delivery by comparing the results of two surveys (one was administered before the pandemic and the other during the pandemic) in public hospitals in Belo Horizonte - Minas Gerais (MG), Brazil. METHODS: This cross-sectional and comparative study analyzed preliminary data from the study "Childbirth and breastfeeding in children of mothers infected with SARS-CoV-2", which was conducted in three referral maternity hospitals in Belo Horizonte - MG during the pandemic in the first half of 2020 in Brazil. The final sample consisted of 1532 eligible women. These results were compared with data from 390 puerperae who gave birth in the three public hospitals in the study "Birth in Belo Horizonte: labor and birth survey", conducted before the pandemic to investigate the changes in practices of labor and delivery care for the mother and her newborn, with or without COVID-19 infection, before and during the pandemic. In this research, "Birth in Belo Horizonte: labor and birth survey", data collection was performed between November 2011 and March 2013 by previously trained nurses. Between study comparisons were performed using Pearson's chi-square test, with a confidence level of 95%, and using Stata statistical program. RESULTS: We found a significant increase in practices recommended by the World Health Organization during the pandemic including the following: diet offering (48.90 to 98.65%), non-pharmacological pain relief (43.84 to 67.57%), and breastfeeding in the newborn´s first hour of life (60.31 to 77.98%) (p < 0.001). We found a significant reduction of non-recommended interventions, such as routine use of episiotomy (15.73 to 2.09%), the Kristeller maneuver (16.55 to 0.94%), oxytocin infusion misused (45.55 to 28.07%), amniotomy (30.81 to 15.08%), and lithotomy position during labor (71.23 to 6.54%) (p < 0.001). CONCLUSION: Our study revealed a statistically significant increase in the proportion of use of recommended practices and a reduction in non-recommended practices during labor and delivery. However, despite advances in the establishment of World Health Organization recommended practices in labor, delivery, and birth, the predominance of interventionist and medicalized practices persists, which is worsened by events, such as the pandemic.

Arterial hypertension and associated factors: National Health Survey, 2019.

OBJECTIVE: To analyze the factors associated with self-reported arterial hypertension, as well as its prevalence in the Brazilian adult population. METHODS: Data from 88,531 individuals aged 18 years or older who responded to the 2019 National Health Survey were analyzed. The outcome studied was self-reported arterial hypertension. Sociodemographic variables and clinical and lifestyle conditions were considered as exposures. The prevalence ratio (PR), crude and adjusted for sex, age, and schooling was used as a measure of association to verify the factors related to its prevalence, obtained by Poisson regression with robust variance. RESULTS: The prevalence of self-reported arterial hypertension was of 23.9% (95%CI: 23.4-24.4). When adjusting for age, sex, and schooling, the adjusted Prevalence Ratios (APR) were higher among: regular health self-assessment (APR = 1.6; 95%CI: 1.5-1.6) and bad health self-assessment (APR = 1.7; 95%CI: 1.6-1.8); self-reference to heart disease (APR = 1.7; 95%CI: 1.6-1.7), diabetes (APR = 1.7; 95%CI: 1.6-1.8), high cholesterol (APR = 1.6; 95%CI: 1.6-1.7), overweight (APR = 1.4; 95%CI: 1.4-1.5), and obesity (APR = 2.0; 95%CI: 1.9-2.1); high salt intake (APR = 1.1; 95%CI: 1.0-1.1); higher among former smokers (APR = 1.1; 95%CI: 1.1-1.2) and lower among smokers (APR = 0.9; 95%CI: 0.8-0.9); and consumption of ultra-processed foods (APR = 0.9; 95%CI: 0.8-0.9). CONCLUSION: A quarter of the Brazilian adult population claims to have arterial hypertension, more prevalent among women and associated with older age groups, Black, mixed-race, and others, low schooling, high salt intake, former smoking, presence of comorbidities, and worse health self-assessment.

Awareness of the diagnosis, treatment, and control of diabetes mellitus in Brazil / Conhecimento do diagnóstico, tratamento e controle do diabetes mellitus no Brasil

ABSTRACT OBJECTIVE To estimate the proportions of awareness, treatment, and control of diabetes mellitus (DM) in the Brazilian adult population. METHOD This is a cross-sectional study, with data from a representative sample of the Brazilian population, taken from the National Health Survey(PNS 2014/2015). Outcomes were defined based on glycated hemoglobin (HbA1c) measurements, self-reported DM diagnosis, and use of hypoglycemic agents or insulin. The proportion of DM awareness, treatment, and control was estimated according to sociodemographic characteristics, health conditions, and access to health services, and their respective 95% confidence intervals. RESULTS DM prevalence in the Brazilian population was of 8.6% (95%CI: 7.8-9.3): 68.2% (95%CI: 63.9-72.3) were aware of their diagnosis, 92.2% (95%CI: 88.6-94.7) of those who were aware were undergoing drug treatments, and, of these, 35.8% (95%CI: 30.5-41.6) had controlled HbA1c levels. The proportions of DM awareness, control, and treatment were lower in men aged 18 to 39 years, individuals with low education, without health insurance, and beneficiaries of the Bolsa Família program. CONCLUSION Approximately one in ten Brazilians has DM. A little more than half of this population is aware of their diagnosis, a condition measured by HbA1c dosage and clinical diagnosis. Among those who know, the vast majority are undergoing drug treatments. However, less than half of these have their HbA1c levels controlled. Worse scenarios were found in subgroups with high social vulnerability.

Accommodative and binocular vision dysfunctions in a Portuguese clinical population

Background: Several studies have suggested that accommodative and non-strabismic binocular dysfunctions are commonly encountered in optometric practice. This study aims to verify whether these findings apply to a Portuguese clinical population.MethodsThis study included consecutive nonpresbyopic subjects that came to two Portuguese optometric clinics over a period of six months. A complete visual exam was conducted and included the measurement of visual acuity (VA), refraction, near point of convergence (NPC), distance and near phoria, near and distance fusional vergences, amplitude of accommodation (AA), monocular accommodative facility (MAF), relative accommodation and lag of accommodation.Results156 subjects with a mean age of 24.9 ± 5.3 years (from 18 to 35 years old) participated in the study. Of all subjects, 32 % presented binocular vision and/or accommodative disorders accompanied or not by refractive errors. Moreover, 21.1 % had accommodative disorders, and 10.9 % had a binocular vision dysfunction. Accommodative insufficiency (11.5 %) was the most prevalent disorder, followed by convergence insufficiency (7.1 %) and accommodative infacility (5. 8 %).ConclusionsClinicians should be aware that about one third of the optometric clinical population could have accommodative and/or non-strabismic binocular disorders. Accommodative insufficiency was the most prevalent dysfunction presented in the studied population, followed by accommodative infacility and convergence insufficiency. (AU)

Intervalos de referência de parâmetros de creatinina e hemoglobina glicosilada para a população adulta brasileira: pesquisa nacional de saúde / Intervalos de referencia de los parámetros creatinina y hemoglobina glicosilada para la población adulta brasileña: pesquisa nacional de saúde / Reference intervals of creatinine and glycated hemoglobin parameters for the brazilian adult population: national health survey

RESUMO Objetivo: estimar intervalos de referência (IR) de creatinina e hemoglobina glicosilada (HbA1c) na população adulta brasileira. Métodos: estudo transversal, utilizando na base de dados Pesquisa Nacional de Saúde (PNS), entre 2014-2015, composta por 8.952 adultos. Para estabelecer IR, aplicaram-se critérios de exclusão, removeram-se outliers e foi feita estratificação. Após esses procedimentos, a amostra constitui-se de 2.723 adultos para HbA1c e de 2.738 adultos para creatinina. Avaliaram-se diferenças pelos testes Mann Withney e Kruskal Wallis (p≤0,05). Resultados: homens (IR 0,69-1,25; mediana 0,95 mg/dL) apresentaram maiores IR para creatinina que mulheres (IR 0,53-1,05; mediana 0,74 mg/dL) e tiveram maiores valores de limites inferiores (LI) e mediana de HbA1c (sexo masculino: IR: 4,55-5,97; mediana 5,3%; sexo feminino: IR 4,49-5,97; mediana 5,20%) (p≤0,05). Nas mulheres, IR para creatinina foram mais elevados entre 45 a 59 anos (IR: 0,55-1,04; mediana 0,77 mg/dL) e a partir dos 60 anos (IR: 0,54-0,98; mediana 0,77 mg/dL (p≤0,05). Para HbA1c, homens apresentaram IR mais elevados a partir de 60 anos (IR 4,65-6,07; mediana 5,44%) e mulheres a partir de 45 anos (45 a 59 anos: IR 4,61-6,05; mediana 5,40%; e 60 anos ou mais: IR 4,82-6,03; mediana 5,50%) (p≤0,05). Para creatina, foram observados menores LI dos IR e mediana mais proeminente nos adultos de raça/cor branca (IR: 0,56-1,19; mediana 0,85%) em comparação com a parda (IR: 0,55-1,19; mediana 0,84%) (p≤0,05). Conclusão: IR próprios possibilitam desvelar as condições de saúde dos adultos brasileiros e podem subsidiar a identificação adequada de doença renal crônica e diabetes.

RESUMEN Objetivo: estimar los intervalos de referencia (IR) de creatinina y hemoglobina glicosilada (HbA1c) en la población adulta brasileña. Métodos: estudio transversal, utilizando la base de datos Pesquisa Nacional de Saúde (PNS), entre 2014-2015, compuesto por 8.952 adultos. Para establecer la IR, se aplicaron criterios de exclusión, se eliminaron los valores atípicos y se realizó una estratificación. Tras estos procedimientos, la muestra estaba formada por 2.723 adultos para la HbA1c y 2.738 adultos para la creatinina. Las diferencias se evaluaron mediante las pruebas de Mann Withney y Kruskal Wallis (p≤0,05). Resultados: los hombres (IR 0,69-1,25; mediana 0,95 mg/dL) tenían un IR de creatinina más alto que las mujeres (IR 0,53-1,05; mediana 0,74 mg/dL) y presentaban valores de límite inferior (LI) y mediana de HbA1c más altos (hombre: IR: 4,55-5,97; mediana 5,3%; mujer: IR 4,49-5,97; mediana 5,20%) (p≤0,05). En las mujeres, los IR para la creatinina fueron mayores entre los 45 y los 59 años (IR: 0,55-1,04; mediana 0,77 mg/dL) y a partir de los 60 años (IR: 0,54-0,98; mediana 0,77 mg/dL (p≤0,05). En cuanto a la HbA1c, los hombres mostraron una IR más alta a partir de los 60 años (IR 4,65-6,07; mediana 5,44%) y las mujeres a partir de los 45 años (45 a 59 años: IR 4,61-6,05; mediana 5,40%; y 60 años o más: IR 4,82-6,03; mediana 5,50%) (p≤0,05). En el caso de la creatina, observamos un menor LI de los IR y una mediana más prominente en los adultos blancos (IR: 0,56-1,19; mediana 0,85%) en comparación con los adultos morenos (IR: 0,55-1,19; mediana 0,84%) (p≤0,05). Conclusión: las IR propias permiten desvelar las condiciones de salud de los adultos brasileños y pueden subsidiar la correcta identificación de la enfermedad renal crónica y la diabetes.

ABSTRACT Objective : to estimate reference intervals (RIs) of creatinine and glycated hemoglobin (HbA1c) in the Brazilian adult population. Methods : a cross-sectional study, using the National Health Survey (Pesquisa Nacional de Saúde, PNS) database, between 2014-2015, consisting of 8,952 adults. To establish RIs, exclusion criteria were applied, outliers were removed and stratification was performed. After these procedures, the sample consisted of 2,723 adults for HbA1c and 2,738 adults for creatinine. Differences were evaluated by means of the Mann Whitney and Kruskal Wallis tests (p≤0.05). Results : men (RI: 0.69-1.25; median: 0.95 mg/dL) had higher RIs for creatinine than women (RI: 0.53-1.05; median: 0.74 mg/dL) and higher lower limit (LL) values and median HbA1c (male: RI: 4.55-5.97; median: 5.3%; female: RI: 4.49-5.97; median: 5.20%) (p≤0.05). In women, the RIs for creatinine were higher in the age groups between 45 and 59 years old (RI: 0.55-1.04; median: 0.77 mg/dL) and from 60 years old (RI: 0.54-0.98; median: 0.77 mg/dL (p≤0.05). For HbA1c, men had higher RIs from age 60 (RI: 4.65-6.07; median: 5.44%) and women from 45 years old (45-59: RI: 4.61-6.05; median: 5.40%; and 60 years old or more: RI: 4.82-6.03; median: 5.50%) (p≤0.05). For creatinine, lower RI LLs and more prominent medians were observed in white-skinned adults (RI: 0.56-1.19; median: 0.85%) when compared to brown-skinned (RI: 0.55-1.19; median: 0.84%) (p≤0.05). Conclusion : appropriate RIs make it possible to unveil the health conditions of Brazilian adults and can support proper identification of chronic kidney disease and diabetes.

Tendências temporais de internações de crianças por condições sensíveis à atenção primária em Minas Gerais, Brasil / Tendencias temporales de admisión infantil por condiciones sensibles a la atención primaria en Minas Gerais, Brasil / Temporal tendencies in hospitalization of children for primary care-sensitive conditions in Minas Gerais, Brazil

RESUMO Objetivo: analisar a tendência das internações por condições sensíveis à atenção primária em crianças menores de cinco anos de idade, no estado de Minas Gerais. Métodos: estudo ecológico de séries temporais utilizou registros do Sistema de Informação Hospitalar, período de 2008 a 2018. As análises de tendência foram realizadas pelo método de Prais-Winsten para verificar tendências: estacionárias (p > 0,05), decrescentes (p < 0,05 e coeficiente de regressão negativo) ou ascendentes (p < 0,05 e coeficiente de regressão positivo) por região de saúde e por grupo etário (até um ano e de um a quatro anos). Resultados: houve tendência decrescente de internações entre crianças no estado (variação percentual anual = -4,96%; p < 0,05), com redução de internações por gastroenterites infecciosas e complicações, pneumonias bacterianas e asma. Observou-se aumento de internações por anemia; doenças pulmonares e infecções de ouvido, nariz e garganta. Para crianças menores de um ano, foi observado que as internações por doenças preveníveis por imunização e condições sensíveis apresentaram tendência ascendente (ß=5,69 e p < 0,05), com destaque para a sífilis congênita. Conclusões: o cenário de Minas Gerais é similar ao de outros estados brasileiros, nos quais se observa redução de internação de crianças de até cinco anos, com aumento de internações por anemia, doenças pulmonares e infecção de ouvido, nariz e garganta. Ainda que existam melhorias nas práticas e políticas voltadas para a saúde da criança, os achados reforçam o planejamento de ações para o cuidado a agravos preveníveis na atenção primária.

ABSTRACT Objective: to analyze the tendency of hospitalizations for primary care-sensitive conditions in children under five years of age in the state of Minas Gerais. Methods: an ecological time series study used records from the Hospital Information System, from 2008 to 2018. Tendency analyzes were performed using the Prais-Winsten method to verify tendencies: stationary (p > 0.05), decreasing (p < 0.05 and negative regression coefficient) or increasing (p < 0.05 and positive regression coefficient) by health region and by age group (up to one year and from one to four years). Results: there was a downward tendency in hospitalizations among children in the state (annual percentage variation = -4.96%; p < 0.05), with a reduction in hospitalizations for infectious gastroenteritis and complications, bacterial pneumonia, and asthma. An increase in hospitalizations due to anemia was observed, lung diseases and ear, nose, and throat infections. For children under one year old, it was observed that hospitalizations for diseases preventable by immunization and sensitive conditions showed an upward tendency (ß=5.69 and p < 0.05), with emphasis on congenital syphilis. Conclusions: the scenario of Minas Gerais is similar to that of other Brazilian states, in which there is a reduction in hospitalization of children up to five years old, with an increase in hospitalizations for anemia, lung diseases and ear, nose and throat infections. Although there are improvements in practices and policies aimed at children's health, the findings reinforce the planning of actions for the care of preventable diseases in primary care.

MCL1 alternative polyadenylation is essential for cell survival and mitochondria morphology.

Alternative polyadenylation in the 3' UTR (3' UTR-APA) is a mode of gene expression regulation, fundamental for mRNA stability, translation and localization. In the immune system, it was shown that upon T cell activation, there is an increase in the relative expression of mRNA isoforms with short 3' UTRs resulting from 3' UTR-APA. However, the functional significance of 3' UTR-APA remains largely unknown. Here, we studied the physiological function of 3' UTR-APA in the regulation of Myeloid Cell Leukemia 1 (MCL1), an anti-apoptotic member of the Bcl-2 family essential for T cell survival. We found that T cells produce two MCL1 mRNA isoforms (pA1 and pA2) by 3' UTR-APA. We show that upon T cell activation, there is an increase in both the shorter pA1 mRNA isoform and MCL1 protein levels. Moreover, the less efficiently translated pA2 isoform is downregulated by miR-17, which is also more expressed upon T cell activation. Therefore, by increasing the expression of the more efficiently translated pA1 mRNA isoform, which escapes regulation by miR-17, 3' UTR-APA fine tunes MCL1 protein levels, critical for activated T cells' survival. Furthermore, using CRISPR/Cas9-edited cells, we show that depletion of either pA1 or pA2 mRNA isoforms causes severe defects in mitochondria morphology, increases apoptosis and impacts cell proliferation. Collectively, our results show that MCL1 alternative polyadenylation has a key role in the regulation of MCL1 protein levels upon T cell activation and reveal an essential function for MCL1 3' UTR-APA in cell viability and mitochondria dynamics.

Association between Adiposity Indexes and Kidney Disease: Findings from the Longitudinal Study of Adult Health (Elsa-Brazil).

INTRODUCTION: Chronic kidney disease (CKD) is a public health problem and it is associated with a high risk of mortality. Overweight and obesity are known as independent risk factors for CKD. OBJECTIVE: To investigate the association between adiposity indexes and kidney disease. METHODS: This study included 14,636 adults from ELSA-Brazil. Outcome variables: altered glomerular filtration rate (GFR), categorized as yes (GFR <60 mL/min/1.73 m2) and no (GFR ≥60 mL/min/1.73 m2), albuminuria, estimated by albumin-creatinine ratio and categorized as yes (≥30 mg/g) and no (<30 mg/g), and presence of chronic kidney disease (CKD) (altered GFR and/or albuminuria). Exposure variables: obesity and overweight (body mass index (BMI)≥30 and ≥25 kg/m2, respectively), high waist circumference (WC) (≥102 cm in men and ≥88 cm in women), high waist-to-hip ratio (WHR) (≥0.90 in men and ≥0.85 in women), and high waist-to-height ratio (WHtR) (≥0.5). To estimate the association between main exposures and outcomes, logistic regression analyses were performed using models adjusted for sociodemographic variables (age, gender, race/skin color, education), behavioral (smoking, physical activity, alcohol consumption), components of the metabolic syndrome (HDL cholesterol, triglycerides, hypertension, diabetes mellitus) and history of cardiovascular disease (myocardial infarction, angina or heart failure). RESULTS: Individuals with obesity, high WC, WHR and WHtR were more prone to albuminuria when compared to individuals with normal values for these measures. It was also observed that these altered measures were positively associated with the presence of CKD. CONCLUSION: Adiposity indexes have a direct and significant association with albuminuria and CKD.

Accommodative and binocular vision dysfunctions in a Portuguese clinical population.

BACKGROUND: Several studies have suggested that accommodative and non-strabismic binocular dysfunctions are commonly encountered in optometric practice. This study aims to verify whether these findings apply to a Portuguese clinical population. METHODS: This study included consecutive nonpresbyopic subjects that came to two Portuguese optometric clinics over a period of six months. A complete visual exam was conducted and included the measurement of visual acuity (VA), refraction, near point of convergence (NPC), distance and near phoria, near and distance fusional vergences, amplitude of accommodation (AA), monocular accommodative facility (MAF), relative accommodation and lag of accommodation. RESULTS: 156 subjects with a mean age of 24.9 ± 5.3 years (from 18 to 35 years old) participated in the study. Of all subjects, 32 % presented binocular vision and/or accommodative disorders accompanied or not by refractive errors. Moreover, 21.1 % had accommodative disorders, and 10.9 % had a binocular vision dysfunction. Accommodative insufficiency (11.5 %) was the most prevalent disorder, followed by convergence insufficiency (7.1 %) and accommodative infacility (5. 8 %). CONCLUSIONS: Clinicians should be aware that about one third of the optometric clinical population could have accommodative and/or non-strabismic binocular disorders. Accommodative insufficiency was the most prevalent dysfunction presented in the studied population, followed by accommodative infacility and convergence insufficiency.

Arterial hypertension and associated factors: National Health Survey, 2019 / Hipertensão arterial e fatores associados: Pesquisa Nacional de Saúde, 2019

ABSTRACT OBJECTIVE To analyze the factors associated with self-reported arterial hypertension, as well as its prevalence in the Brazilian adult population. METHODS Data from 88,531 individuals aged 18 years or older who responded to the 2019 National Health Survey were analyzed. The outcome studied was self-reported arterial hypertension. Sociodemographic variables and clinical and lifestyle conditions were considered as exposures. The prevalence ratio (PR), crude and adjusted for sex, age, and schooling was used as a measure of association to verify the factors related to its prevalence, obtained by Poisson regression with robust variance. RESULTS The prevalence of self-reported arterial hypertension was of 23.9% (95%CI: 23.4-24.4). When adjusting for age, sex, and schooling, the adjusted Prevalence Ratios (APR) were higher among: regular health self-assessment (APR = 1.6; 95%CI: 1.5-1.6) and bad health self-assessment (APR = 1.7; 95%CI: 1.6-1.8); self-reference to heart disease (APR = 1.7; 95%CI: 1.6-1.7), diabetes (APR = 1.7; 95%CI: 1.6-1.8), high cholesterol (APR = 1.6; 95%CI: 1.6-1.7), overweight (APR = 1.4; 95%CI: 1.4-1.5), and obesity (APR = 2.0; 95%CI: 1.9-2.1); high salt intake (APR = 1.1; 95%CI: 1.0-1.1); higher among former smokers (APR = 1.1; 95%CI: 1.1-1.2) and lower among smokers (APR = 0.9; 95%CI: 0.8-0.9); and consumption of ultra-processed foods (APR = 0.9; 95%CI: 0.8-0.9). CONCLUSION A quarter of the Brazilian adult population claims to have arterial hypertension, more prevalent among women and associated with older age groups, Black, mixed-race, and others, low schooling, high salt intake, former smoking, presence of comorbidities, and worse health self-assessment.

RESUMO OBJETIVO Analisar os fatores associados à hipertensão arterial autorreferida, bem como sua prevalência, na população de adultos brasileiros. MÉTODOS Foram analisados dados de 88.531 indivíduos de 18 anos ou mais que responderam à Pesquisa Nacional de Saúde de 2019. O desfecho estudado foi a hipertensão arterial autorreferida. Como exposições, foram consideradas variáveis sociodemográficas, condições clínicas e de estilo de vida. Para verificar os fatores associados à prevalência, usou-se como medida de associação a razão de prevalência (RP) bruta e ajustada por sexo, idade e escolaridade, obtidas por meio da Regressão de Poisson com variância robusta. RESULTADOS A prevalência da hipertensão arterial autorreferida foi de 23,9% (IC95% 23,4-24,4). Ao ajustar por idade, sexo e escolaridade, as Razões de Prevalência ajustadas (RPaj) foram mais elevadas entre: auto avaliação de saúde regular (RPaj = 1,6; IC95% 1,5-1,6) e ruim (RPaj = 1,7; IC95% 1,6-1,8); autorreferência a doença do coração (RPaj = 1,7; IC95% 1,6-1,7), diabetes (RPaj = 1,7; IC95% 1,6-1,8), colesterol elevado (RPaj = 1,6; IC95% 1,6-1,7), sobrepeso (RPaj = 1,4; IC95% 1,4-1,5) e obesidade (RPaj = 2,0; IC95% 1,9-2,1); consumo elevado de sal (RPaj = 1,1; IC95% 1,0-1,1); entre ex-fumantes (RPaj = 1,1; IC95% 1,1-1,2) e menor entre fumantes (RPaj = 0,9; IC95% 0,8-0,9) e consumo de alimentos ultraprocessados (RPaj = 0,9; IC95% 0,8-0,9). CONCLUSÃO Um quarto da população adulta brasileira afirma ter hipertensão arterial, de forma mais prevalente entre as mulheres e associada às maiores faixas etárias, cor da pele/raça preta, parda e outras, baixa escolaridade, consumo elevado de sal, ex-tabagismo, presença de comorbidades e pior autoavaliação de saúde.
