Aging changes the expression of adenosine receptors, insulin-like growth factor 1 (IGF1), and hypoxia-inducible factor 1α (HIF1α) in hypothalamic astrocyte cultures.

The aging process induces neurochemical alterations in different brain regions, including hypothalamus. This pivotal area of the central nervous system (CNS) is crucial for detection and integration of nutritional and hormonal signals from the periphery of the body to maintain metabolic homeostasis. Astrocytes support the CNS homeostasis, energy metabolism, and inflammatory response, as well as increasing evidence has highlighted a critical role of astrocytes in orchestrating hypothalamic functions and in gliocrine system. In this study, we aimed to investigate the age-dependent mRNA expression of adenosine receptors, the insulin-like growth factor 1 receptor (IGF1R), and the hypoxia-inducible factor 1α (HIF1α), in addition to the levels of IGF1 and HIF1α in hypothalamic astrocyte cultures derived from newborn, adult, and aged rats. Our results revealed age-dependent changes in adenosine receptors, as well as a decrease in IGF1R/IGF1 and HIF1α. Of note, adenosine receptors, IGF1, and HIF1α are affected by inflammatory, redox, and metabolic processes, which can remodel hypothalamic properties, as observed in aging brain, reinforcing the role of hypothalamic astrocytes as targets for understanding the onset and/or progression of age-related diseases.

Interleukin-10 GCC/GCC haplotype is associated high risk of acute GVHD in patients undergoing allogeneic HSCT in the southern of Brazil.

INTRODUCTION: Hematopoietic Stem Cell Transplant (HSCT) is currently an important curative treatment for many patients with malignant and non-malignant diseases. Graft versus host disease (GVHD) represents a major complication in allogeneic HSCT recipients. Several polymorphisms in cytokine genes have recently been investigated as candidates for risk factors for acute-GVHD (aGVHD) in allogeneic hematopoietic stem cell transplantation (allo-HSCT). OBJECTIVE: In this study, we analyzed specific interleukin (IL)-10 haplotypes polymorphisms, in a cohort of 99 patients and their respective allo-HSCT donors for aGVHD and risk. RESULTS: An association was found between IL-10 promoter haplotype polymorphisms at positions -1082, -819 and - 592 with the occurrence of aGVHD. Patients who have the GCC/GCC haplotype are at increased risk of aGVHD (P = 0.017, HR: 5.42 (95% CI: 1.34-21.84). In the donors group and severity of aGVHD as not found statistical significancy. CONCLUSION: The results obtained show the IL-10 GCC/GCC haplotype can be an important biomarker to identify the greatest risk of aGVHD in the patient undergoing HSCT.

Single-Cell Transcription Mapping of Murine and Human Mammary Organoids Responses to Female Hormones.

During female adolescence and pregnancy, rising levels of hormones result in a cyclic source of signals that control the development of mammary tissue. While such alterations are well understood from a whole-gland perspective, the alterations that such hormones bring to organoid cultures derived from mammary glands have yet to be fully mapped. This is of special importance given that organoids are considered suitable systems to understand cross species breast development. Here we utilized single-cell transcriptional profiling to delineate responses of murine and human normal breast organoid systems to female hormones across evolutionary distinct species. Collectively, our study represents a molecular atlas of epithelial dynamics in response to estrogen and pregnancy hormones.

Basal cell adenocarcinoma of the soft palate: A closer look for an exceedingly rare salivary gland tumor.

Basal cell adenocarcinoma (BCAd) is an extremely rare primary biphasic carcinoma of the salivary glands with few well-documented cases reported in the literature. Herein, we report a rare case of a 44-year-old male patient who presented an oral medicine service with an erythematous nodular lesion on the soft palate, measuring 1.5 cm in its largest diameter, with a 5-year duration. The clinical diagnosis was pleomorphic adenoma, and an excisional biopsy was performed. Histopathological analysis revealed a biphasic infiltrative tumor composed of a mixture of central ductal cells and abluminal basal cells with slight atypia arranged in solid, trabecular, tubular and cribriform growth patterns in a loose stroma. The peripheral cells show a palisading arrangement with round hyperchromatic nuclei and scanty cytoplasm. Occasional mitotic figures were seen. Few spindle-shaped cells suggestive of myoepithelial cells were present in the stroma surrounding the basaloid tumor nests. The diagnosis was BCAd. The patient was referred to a head and neck service and has been followed up for 8 months with no signs of recurrence. In conclusion, although the diagnosis of BCAd can be challenging due to its rarity and morphological overlap with other salivary gland lesions, a meticulous morphological assessment is key for accurate diagnosis, especially in cases originating from minor salivary glands. Surgical excision with a wide safety margin is the treatment of choice and long-term follow-up is recommended to monitor possible recurrences.

Cathepsin B Is Not an Intrinsic Factor Related to Asparaginase Resistance of the Acute Lymphoblastic Leukemia REH Cell Line.

L-Asparaginase (ASNase) is a biopharmaceutical used as an essential drug in the treatment of acute lymphoblastic leukemia (ALL). Yet, some cases of ALL are naturally resistant to ASNase treatment, which results in poor prognosis. The REH ALL cell line, used as a model for studying the most common subtype of ALL, is considered resistant to treatment with ASNase. Cathepsin B (CTSB) is one of the proteases involved in the regulation of in vivo ASNase serum half-life and it has also been associated with the progression and resistance to treatment of several solid tumors. Previous works have shown that, in vitro, ASNase is degraded when incubated with REH cell lysate, which is prevented by a specific CTSB inhibitor, suggesting a function of this protease in the ASNase resistance of REH cells. In this work, we utilized a combination of CRISPR/Cas9 gene targeting and enzymatic measurements to investigate the relevance of CTSB on ASNase treatment resistance in the ALL model cell line. We found that deletion of CTSB in REH ALL cells did not confer ASNase treatment sensitivity, thus suggesting that intrinsic expression of CTSB is not a mechanism that drives the resistant nature of these ALL cells to enzymes used as the first-line treatment against leukemia.

Gestational Breast Cancer - a Review of Outcomes, Pathophysiology, and Model Systems.

The onset of pregnancy marks the start of offspring development, and represents the key physiological event that induces re-organization and specialization of breast tissue. Such drastic tissue remodeling has also been linked to epithelial cell transformation and the establishment of breast cancer (BC). While patient outcomes for BC overall continue to improve across subtypes, prognosis remains dismal for patients with gestational breast cancer (GBC) and post-partum breast cancer (PPBC), as pregnancy and lactation pose additional complications and barriers to several gold standard clinical approaches. Moreover, delayed diagnosis and treatment, coupled with the aggressive time-scale in which GBC metastasizes, inevitably contributes to the higher incidence of disease recurrence and patient mortality. Therefore, there is an urgent and evident need to better understand the factors contributing to the establishment and spreading of BC during pregnancy. In this review, we provide a literature-based overview of the diagnostics and treatments available to patients with BC more broadly, and highlight the treatment deficit patients face due to gestational status. Further, we review the current understanding of the molecular and cellular mechanisms driving GBC, and discuss recent advances in model systems that may support the identification of targetable approaches to block BC development and dissemination during pregnancy. Our goal is to provide an updated perspective on GBC, and to inform critical areas needing further exploration to improve disease outcome.

Loss of IRF5 increases ribosome biogenesis leading to alterations in mammary gland architecture and metastasis.

Despite the progress made in identifying cellular factors and mechanisms that predict progression and metastasis, breast cancer remains the second leading cause of death for women in the US. Using The Cancer Genome Atlas and mouse models of spontaneous and invasive mammary tumorigenesis, we identified that loss of function of interferon regulatory factor 5 (IRF5) is a predictor of metastasis and survival. Histologic analysis of Irf5 -/- mammary glands revealed expansion of luminal and myoepithelial cells, loss of organized glandular structure, and altered terminal end budding and migration. RNA-seq and ChIP-seq analyses of primary mammary epithelial cells from Irf5 +/+ and Irf5 -/- littermate mice revealed IRF5-mediated transcriptional regulation of proteins involved in ribosomal biogenesis. Using an invasive model of breast cancer lacking Irf5 , we demonstrate that IRF5 re-expression inhibits tumor growth and metastasis via increased trafficking of tumor infiltrating lymphocytes and altered tumor cell protein synthesis. These findings uncover a new function for IRF5 in the regulation of mammary tumorigenesis and metastasis. Highlights: Loss of IRF5 is a predictor of metastasis and survival in breast cancer.IRF5 contributes to the regulation of ribosome biogenesis in mammary epithelial cells.Loss of IRF5 function in mammary epithelial cells leads to increased protein translation.

Greenhouse Gas Emissions and Crossbred Cow Milk Production in a Silvopastoral System in Tropical Mexico.

In Mexico, pasture degradation is associated with extensive pastures; additionally, under these conditions, livestock activities contribute considerably to greenhouse gas (GHG) emissions. Among the options to improve grazing systems and reduce GHG emissions, silvopastoral systems (SPS) have been recommended. The objectives of this work were to quantify the N outflow in a soil-plant-animal interface, as well as the CH4 emissions and milk production in an SPS with woody legumes (Leucaena leucocephala) that is associated with stargrass (Cynodon nlemfuensis). This was then compared with stargrass in a monoculture system (MS) in the seasons (dry and rainy period) over a two-year period. Dung was collected from the animals of each of the grazing systems and applied fresh to the land plots. Fresh dung and urine were collected from the cows of each grazing system and were applied to the experimental plots. In addition, the soil CH4 and N2O contents were measured to quantify the emissions. Average milk yield by seasons was similar: MS (7.1 kg per animal unit (AU)/day-1) and SPS (6.31 kg per AU/day-1). Cows in the MS had a mean N intake of 171.9 g/UA day-1 without seasonal variation, while the SPS animals' mean N intake was 215.7 g/UA day-1 for both seasons. For the urine applied to soil, the N2O outflow was higher in the MS (peak value = 1623.9 µg N-N2O m-2 h-1). The peak value for the SPS was 755.9 µg of N-N2O m-2 h-1. The N2O emissions were higher in the rainy season (which promotes denitrification). The values for the feces treatment were 0.05% (MS) and 0.01% (SPS). The urine treatment values were 0.52% (MS) and 0.17% (SPS). The emissions of CH4 showed that the feces of the SPS systems resulted in a higher accumulation of gas in the rainy season (29.8 g C ha-1), followed by the feces of the MS system in the dry season (26.0 g C ha-1). Legumes in the SPS helped to maintain milk production, and the N2O emissions were lower than those produced by the MS (where the pastures were fertilized with N).

Age-dependent effects of resveratrol in hypothalamic astrocyte cultures.

OBJECTIVES: The hypothalamus plays critical roles in maintaining brain homeostasis and increasing evidence has highlighted astrocytes orchestrating several of hypothalamic functions. However, it remains unclear how hypothalamic astrocytes participate in neurochemical mechanisms associated with aging process, as well as whether these cells can be a target for antiaging strategies. In this sense, the aim of this study is to evaluate the age-dependent effects of resveratrol, a well-characterized neuroprotective compound, in primary astrocyte cultures derived from the hypothalamus of newborn, adult, and aged rats. METHODS: Male Wistar rats (2, 90, 180, and 365 days old) were used in this study. Cultured astrocytes from different ages were treated with 10 and 100 µM resveratrol and cellular viability, metabolic activity, astrocyte morphology, release of glial cell line-derived neurotrophic factor (GDNF), transforming growth factor ß (TGF-ß), tumor necrosis factor α (TNF-α), interleukins (IL-1ß, IL-6, and IL-10), as well as the protein levels of Nrf2 and HO-1 were evaluated. RESULTS: In vitro astrocytes derived from neonatal, adults, and aged animals changed metabolic activity and the release of trophic factors (GDNF and TGF-ß), as well as the inflammatory mediators (TNF-α, IL-1ß, IL-6, and IL-10). Resveratrol prevented these alterations. In addition, resveratrol changed the immunocontent of Nrf2 and HO-1. The results indicated that the effects of resveratrol seem to have a dose- and age-associated glioprotective role. CONCLUSION: These findings demonstrate for the first time that resveratrol prevents the age-dependent underlying functional reprogramming of in vitro hypothalamic astrocytes, reinforcing its antiaging activity, and consequently, its glioprotective role.

Immature natural killer cells promote progression of triple-negative breast cancer.

Natural killer (NK) cells are cytotoxic lymphocytes that accumulate within the tumor microenvironment and are generally considered to be antitumorigenic. Using single-cell RNA sequencing and functional analysis of multiple triple-negative breast cancer (TNBC) and basal tumor samples, we observed a unique subcluster of Socs3highCD11b-CD27- immature NK cells that were present only in TNBC samples. These tumor-infiltrating NK cells expressed a reduced cytotoxic granzyme signature and, in mice, were responsible for activating cancer stem cells through Wnt signaling. NK cell-mediated activation of these cancer stem cells subsequently enhanced tumor progression in mice, whereas depletion of NK cells or Wnt ligand secretion from NK cells by LGK-974 decreased tumor progression. In addition, NK cell depletion or inhibition of their function improved anti-programmed cell death ligand 1 (PD-L1) antibody or chemotherapy response in mice with TNBC. Furthermore, tumor samples from patients with TNBC and non-TNBC revealed that increased numbers of CD56bright NK cells were present in TNBC tumors and were correlated to poor overall survival in patients with TNBC. Together, our findings identify a population of protumorigenic NK cells that may be exploited for both diagnostic and therapeutic strategies to improve outcomes for patients with TNBC.

Discriminação social em adultos com deficiência auditiva nos serviços de saúde brasileiro: resultados da Pesquisa Nacional de Saúde / Self-reported discrimination against adults with hearing loss in Brazilian health services: results of the National Health Survey

Resumo O artigo tem como objetivo estimar a prevalência de discriminação social autorreferida em pessoas com deficiência auditiva nos serviços de saúde brasileiros, verificando fatores associados à discriminação. Estudo transversal de base populacional, com dados de um inquérito epidemiológico domiciliar realizado ponderadamente em todo o território brasileiro no ano de 2013. A amostra final deste estudo compreendeu 1.464 adultos com perda auditiva autorreferida. Utilizou-se regressão de Poisson com variância robusta para cálculo de razões de prevalência (RP) brutas e ajustadas para a investigação das prevalências de discriminação autorreferida nos serviços de saúde e seus respectivos intervalos de confiança de 95%. A prevalência de discriminação em adultos com deficiência auditiva nos serviços de saúde brasileiros foi de 15%. Indivíduos de cor/raça preta e que relataram que a perda auditiva limita as suas atividades de vida diária apresentaram maior associação com discriminação. Pessoas com deficiência auditiva de cor/raça preta e que apresentam limitação nas atividades da vida diária em decorrência da perda auditiva relataram maior discriminação nos serviços de saúde. Estratégias de enfrentamento à discriminação de profissionais da área da saúde devem ser implementadas para que esse cenário seja modificado.

Abstract This article aims to estimate the prevalence of self-reported discrimination against people with hearing loss in Brazilian health services and analyze associated factors. We conducted a cross-sectional population-based study using data from the 2013 National Health Survey. The final study sample comprised 1,464 individuals with self-reported hearing loss. Poisson regression was used to calculate crude and adjusted prevalence ratios (PR) and respective 95% confidence intervals. The overall prevalence of discrimination was 15%. Prevalence was higher among black people and respondents who reported experiencing limitations in activities of daily living. Prevalence of discrimination in Brazilian health services was highest in black people with limitations in activities of daily living. The implementation of policies and actions to address this problem is recommended, including strategies during the education and training of health professionals.

Effects of long-term resveratrol treatment in hypothalamic astrocyte cultures from aged rats.

Aging is intrinsically related to metabolic changes and characterized by the accumulation of oxidative and inflammatory damage, as well as alterations in gene expression and activity of several signaling pathways, which in turn impact on homeostatic responses of the body. Hypothalamus is a brain region most related to these responses, and increasing evidence has highlighted a critical role of astrocytes in hypothalamic homeostatic functions, particularly during aging process. The purpose of this study was to investigate the in vitro effects of a chronic treatment with resveratrol (1 µM during 15 days, which was replaced once every 3 days), a recognized anti-inflammatory and antioxidant molecule, in primary hypothalamic astrocyte cultures obtained from aged rats (24 months old). We observed that aging process changes metabolic, oxidative, inflammatory, and senescence parameters, as well as glial markers, while long-term resveratrol treatment prevented these effects. In addition, resveratrol upregulated key signaling pathways associated with cellular homeostasis, including adenosine receptors, nuclear factor erythroid-derived 2-like 2 (Nrf2), heme oxygenase 1 (HO-1), sirtuin 1 (SIRT1), proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α), and phosphoinositide 3-kinase (PI3K). Our data corroborate the glioprotective effect of resveratrol in aged hypothalamic astrocytes, reinforcing the beneficial role of resveratrol in the aging process.

Genetic diversity of Macroptilium accessions considering the increase in air temperature

Climate changes can influence the genetic diversity of forage plants, which may contribute to the improvement and development of new species. Therefore, this research aimed to evaluate the influence of temperature increase on the genetic diversity of Macroptilium accessions based on morphoagronomic descriptors. The experiment was carried out in a growth chamber in a 2×16 factorial arrangement (temperature regimes x Macroptilium accessions), with the temperatures consisting of T1 (20­26­33 °C) and T2 (24.8­30.8­37.8 °C) and 16 accessions. Eleven morphoagronomic descriptors allowed estimating the diversity among accessions. The measurements of genetic dissimilarity enabled us to observe the genetic distance between the studied materials, standing out the accessions T1.M3 and T2.S4 as the most divergent (446.01). The morphoagronomic descriptors percentage of leaves and stem diameter were the most efficient for estimating the diversity between access. Genetic variability points to the adaptation of Macroptilium accessions in the climate change scenario. The accessions more divergent can be explored in genetic breeding programs for the species aiming at the expansion of genetic variability as an adaptation mechanism to heat stress.

Desastre socioambiental de Mariana: implicações nas condições de saúde da população atingida e no processo de trabalho dos serviços de saúde / Mariana socio-environmental disaster: implications for the health conditions of the affected population and the work process of health services

O desastre socioambiental, ocorrido em Mariana, em consequência do rompimento da barragem de Fundão da mineradora Samarco, devastou as comunidades de Bento Rodrigues e de Paracatu de Baixo provocando perdas e danos que podem se desdobrar ao longo do tempo, produzindo efeitos profundos na saúde, no meio ambiente, bem como no contexto de vida e trabalho. Com isso, busca-se analisar o processo saúde-doença e o processo de trabalho nos serviços de saúde destinados à população atingida pelo desastre socioambiental em Mariana. Trata-se de um estudo de caso conduzido pela abordagem qualitativa, descritiva e exploratória, cujo cenário é Mariana, onde se encontram as comunidades diretamente atingidas pelo rompimento da barragem de rejeito de mineração. As fontes de evidências utilizadas foram documentos de domínio público e entrevistas com profissionais de saúde e gestores. Foram escolhidas intencionalmente a Unidade de Saúde de Bento Rodrigues e o dispositivo Conviver, por atenderem exclusivamente as famílias vítimas do desastre. Participaram da pesquisa onze profissionais de saúde e três gestores. Os dados foram analisados por meio da estratégia de proposições teóricas à luz da teoria de Determinação Social do Processo Saúde-Doença. Os resultados revelaram as implicações do desastre nas condições sociais, econômicas, culturais e sobretudo na saúde da população atingida, com consequências relacionadas aos agravos respiratórios e os ocasionados por veiculação hídrica ou contato com a lama toxica de rejeito, e os casos depressivos e demais transtornos psicossociais que intensificaram o sofrimento crônico da população. Já as implicações do desastre no processo de trabalho nos serviços de atendimento exclusivo aos atingidos, evidenciam uma (re)organização do sistema de saúde, o qual enfrentou dificuldades estruturais tanto na fase emergencial quanto de recuperação pós-desastre. Destaca-se que embora os instrumentos do processo de trabalho utilizados pelos profissionais de saúde e gestores, são capazes de acolher, estimular práticas mais integradas e que transcendem a intervenção apenas nos corpos biológicos, ainda assim não são capazes de suprir as necessidades mediadas de saúde dos atingidos, não promovendo respostas às necessidades políticas, sociais e econômicas no que tange à reparação, à indenização e os direitos da população atingida.

The socio-environmental disaster that occurred in Mariana, because of the collapse of the Samarco mining company's Fundão dam, devastated the communities of Bento Rodrigues and Paracatu de Baixo, causing losses and damages that can unfold over time, producing profound effects on health, in the environment, as well as in the context of life and work. With this, we seek to analyze the health-disease process and the work process in health services intended for the population affected by the socio-environmental disaster in Mariana. This is a case study conducted using a qualitative, descriptive and exploratory approach, whose setting is Mariana, where the communities directly affected by the collapse of the mining tailings dam are located. The sources of evidence used were public domain documents and interviews with health professionals and managers. The Bento Rodrigues Health Unit and the Conviver device were intentionally chosen, as they exclusively serve families who were victims of the disaster. Eleven health professionals and three managers participated in the research. The data were analyzed using the strategy of theoretical propositions in light of the theory of Social Determination of the HealthDisease Process. The results revealed the implications of the disaster on social, economic, cultural conditions and above all on the health of the affected population, with consequences related to respiratory problems and those caused by water transport or contact with toxic waste sludge, and depressive cases and other disorders, psychosocial problems that intensified the chronic suffering of the population. The implications of the disaster on the work process in services providing exclusive care to those affected highlight a (re) organization of the health system, which faced structural difficulties in both the emergency and postdisaster recovery phases. It is noteworthy that although the work process instruments used by health professionals and managers are capable of welcoming and stimulating more integrated practices, that transcend intervention only in biological bodies, they are still not capable of meeting mediated health needs of those affected, failing to promote responses to political, social and economic needs in terms of reparation, compensation and the rights of the affected population.

Análise farmacoeconômica do uso de omeprazol por idosos em uma das unidades básicas de saúde do Brasil / Pharmacoeconomic Analysis of the Use of Omeprazole by Elderly Patients in One of the Primary Healthcare Centers in Brazil

O omeprazol é inibidor de bomba de prótons mais prescrito no Brasil e é indicado para o tratamento de doenças por refluxos gastroesofágicos, úlcera péptica, esofagite erosiva, erradicação de Helicobacter pylori, síndrome de Zollinger-Ellison, gastrinomas, gastrite e distúrbios hipersecretores e prevenção de úlcera péptica. O uso indiscriminado e desnecessário, principalmente por idosos, é uma importante questão de saúde pública a ser tratada. Apesar de ser conhecida a existência do uso indiscriminado do omeprazol, identifica-se a necessidade de se verificar como ocorre a prescrição desse medicamento no contexto do Sistema Único de Saúde (SUS) do Brasil. Além disso, acredita-se que estudos que analisam de modo famacoeconômico a prescrição do omeprazol podem contribuir para a revisão ou implementação de diretrizes e protocolos que envolvam o uso desse medicamento. O objetivo foi caracterizar e realizar análise farmacoeconômica do uso do omeprazol em Unidade de Atenção Primária a Saúde (UAPS) em Minas Gerais, Brasil. Trata-se de estudo descritivo com análise das prescrições de 41 pacientes idosos atendidos no período de abril/maio de 2018 e foram identificadas as seguintes variáveis: idade, sexo, dose, indicação, realização de endoscopia, demais medicamentos em uso e custo do tratamento. Na análise farmacoeconômica realizou-se o cálculo do custo médio da quantidade de omeprazol prescrita por paciente e considerou-se a realização ou não de endoscopia. Na população estudada, 29 (70,3%) do sexo feminino com mediana de idade: 69 anos. Apenas em 4 prontuários (9,8%) havia indicação para uso e em 18 (43,9%) pacientes, a utilização era feita há mais de dois anos e em 7 (17,1%) a mais de cinco anos. Apenas 3 (7,3%) realizaram endoscopia e foram utilizados 371 meses totalizando um valor financeiro de R$35.657,23. Os achados sugerem prescrições em longo prazo e sem registro da indicação em prontuário. O custo referente às prescrições poderia ser otimizado com a realização de endoscopia e suspensão do uso, quando constatada ausência de indicação.

Omeprazole is the most prescribed proton pump inhibitor in Brazil and is indicated for the treatment of diseases caused by gastroesophageal reflux, peptic ulcer, erosive esophagitis, eradication of Helicobacter pylori, Zollinger-Ellison syndrome, gastrinomas, gastritis, and hypersecretory disorders, as well as peptic ulcer prevention. The indiscriminate and unnecessary use, mainly by the elderly, is an important public health issue to be addressed. Despite the existence of indiscriminate use of omeprazole being known, there is a need to verify how this medication is prescribed in the context of the Unified Health System (UHS) in Brazil. In addition, it is believed that studies that aim to analyze the prescription of omeprazole in a pharmacoeconomic way can contribute to the review or implementation of guidelines and protocols involving the use of this drug. The objective of this study was to characterize and perform a pharmacoeconomic analysis of the use of omeprazole in a Primary Healthcare Centers (PHC) in Minas Gerais, Brazil. This is a descriptive study analyzing the prescriptions of 41 elderly patients treated in the period of April/May 2018 and the following variables were identified: age, sex, dose, indication, endoscopy, other medications in use, and cost of treatment. In the pharmacoeconomic analysis, the average cost of the amount of omeprazole prescribed per patient was calculated and whether or not endoscopy was performed was considered. In the studied population, 29 (70.3%) were female with a median age: 69 years. Only in 4 medical records (9.8%) was there indication for use, and 18 (43.9%) patients had been using omeprazole for more than two years and 7 (17.1%) for more than five years. Only 3 (7.3%) patients underwent endoscopy, and 371 months-worth of omeprazole were used, totaling a financial value of R$35,657.23. The findings suggest long-term prescriptions and no record of their indication on medical records. The cost related to prescriptions could be optimized by performing endoscopy and discontinuing its use when no indication is found.

Prevalência, incidência e mortalidade associada à taxa de filtração glomerular diminuída em idosos residentes no município de São Paulo: estudo de coorte SABE / Prevalence, incidence and mortality associated with decreased glomerular filtration rate in elderly residents of the city of São Paulo: SABE cohort study

A taxa de filtração glomerular (TFG) é uma medida utilizada para avaliação da função renal. O envelhecimento e o aumento da prevalência de Doenças Crônicas não Transmissíveis (DCNT) acentuam a perda da função renal. O objetivo deste trabalho foi estimar a prevalência, incidência, variação temporal e mortalidade da taxa de filtração glomerar diminuída em idosos residentes no município de São Paulo. Este é um estudo de coorte com dados do Estudo SABE - Saúde, Bem-estar e Envelhecimento com amostra probabilística e representativa dos idosos residentes em São Paulo. Foram utilizados dados da coorte coletados em 2010 e 2016. A variável dependente TFG foi calculada por meio da equação Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) de 2021. Para avaliar fatores associados à prevalência e incidência da TFG diminuída foram realizados teste do qui-quadrado com correção de Rao-Scott e modelo de regressão logística. Para avaliar fatores associados à variação temporal da TFG foram realizados modelos de regressão logística e linear. Para a mortalidade foi utilizado modelo de regressão de Cox. As análises estatísticas foram realizados no programa Stata/SE 13.0 utilizando o modo survey, considerando os pesos amostrais para manter a representatividade da população. A prevalência da TFG diminuída em 2010 foi de 17,3%, a média da TFG foi de 75,6 mL/min/1,73m2 (EP=0,54). A TFG diminuída associou-se positivamente à maior idade, hipertensão, doença cardiovascular, maior número de comorbidades e atividade física foi fator de proteção. A incidência de TFG diminuída no período de 2010 a 2016 foi de 14,9%, cerca de 2,5% a cada ano. Associou-se à incidência de TFG diminuída a maior idade, presença de hipertensão arterial, percepção de saúde regular/ruim/muito ruim e maior número de comorbidades. 68,1% dos idosos tiveram piora da TFG neste período e a queda média da TFG foi de 1 mL/min/1,73m2 ao ano. Idosos com TFG <45 mL/min/1,73m2 tiveram aumento de 50% no risco de óbito quando comparados com aqueles que tinham ≥60 mL/min/1,73m2. O declínio da função renal ocorre muitas vezes de forma silenciosa e a alta prevalência de comorbidades contribui para a piora da TFG. A monitoração da função renal nos idosos é de suma importância para acompanhamento de saúde da população idosa.

The glomerular filtration rate (GFR) is a measure used to assess kidney function. Aging and the increase in the prevalence of Chronic Noncommunicable Diseases (NCDs) accentuate the loss of kidney function. The objective of this study was to estimate the prevalence, incidence, temporal variation and mortality of decreased glomerular filtration rate in elderly residents of the city of São Paulo. This is a cohort study with data from the SABE Study - Health, Wellbeing and Aging with a probabilistic and representative sample of elderly residents in São Paulo. Cohort data collected in 2010 and 2016 were used. The dependent variable GFR was calculated using the 2021 Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. -square with Rao-Scott correction and logistic regression model. To assess factors associated with temporal variation in GFR, logistic and linear regression models were performed. For mortality, a Cox regression model was used. Statistical analyzes were performed using the Stata/SE 13.0 program using survey mode, considering sample weights to maintain representativeness of the population. The prevalence of decreased GFR in 2010 was 17.3%, the mean GFR was 75.6 mL/min/1.73m2 (SE=0.54). Decreased GFR was positively associated with older age, hypertension, cardiovascular disease, a greater number of comorbidities, and physical activity was a protective factor. The incidence of decreased GFR in the period 2010 to 2016 was 14.9%, about 2.5% each year. The incidence of reduced GFR was associated with older age, presence of arterial hypertension, perception of fair/poor/very poor health and a greater number of comorbidities. 68.1% of the elderly had a worsening of GFR in this period and the mean drop in GFR was 1 mL/min/1.73m2 per year. Elderly people with GFR <45 mL/min/1.73m2 had a 50% increase in the risk of death when compared to those with ≥60 mL/min/1.73m2. The decline in renal function often occurs silently and the high prevalence of comorbidities contributes to the worsening of GFR. Monitoring renal function in the elderly is of paramount importance for monitoring the health of the elderly population.
