Type I interferon signaling induces a delayed antiproliferative response in respiratory epithelial cells during SARS-CoV-2 infection.

ABSTRACT: Disease progression during SARS-CoV-2 infection is tightly linked to the fate of lung epithelial cells, with severe cases of COVID-19 characterized by direct injury of the alveolar epithelium and an impairment in its regeneration from progenitor cells. The molecular pathways that govern respiratory epithelial cell death and proliferation during SARS-CoV-2 infection, however, remain unclear. We now report a high-throughput CRISPR screen for host genetic modifiers of the survival and proliferation of SARS-CoV-2-infected Calu-3 respiratory epithelial cells. The top four genes identified in our screen encode components of the same type I interferon (IFN-I) signaling complex­IFNAR1, IFNAR2, JAK1, and TYK2. The fifth gene, ACE2, was an expected control encoding the SARS-CoV-2 viral receptor. Surprisingly, despite the antiviral properties of IFN-I signaling, its disruption in our screen was associated with an increase in Calu-3 cell fitness. We validated this effect and found that IFN-I signaling did not sensitize SARS-CoV-2-infected cultures to cell death but rather inhibited the proliferation of surviving cells after the early peak of viral replication and cytopathic effect. We also found that IFN-I signaling alone, in the absence of viral infection, was sufficient to induce this delayed antiproliferative response in both Calu-3 cells and iPSC-derived type 2 alveolar epithelial cells. Together, these findings highlight a cell autonomous antiproliferative response by respiratory epithelial cells to persistent IFN-I signaling during SARS-CoV-2 infection. This response may contribute to the deficient alveolar regeneration that has been associated with COVID-19 lung injury and represents a promising area for host-targeted therapeutic development.

Ballistic Behavior of Epoxy Composites Reinforced with Amazon Titica Vine Fibers (Heteropsis flexuosa) in Multilayered Armor System and as Stand-Alone Target.

Seeking to improve personal armor equipment by providing mobility and resistance to penetration, this research aimed to explore the potential of sustainable materials in order to assess their ability in ballistic applications. Titica vine fibers (TVFs) extracted from aerial roots of Heteropsis flexuosa from the Amazon region were incorporated at 10, 20, 30, and 40 vol% into an epoxy matrix for applications in ballistic multilayered armor systems (MASs) and stand-alone tests for personal protection against high-velocity 7.62 mm ammunition. The back-face signature (BFS) depth measured for composites with 20 and 40 vol% TVFs used as an intermediate layer in MASs was 25.6 and 32.5 mm, respectively, and below the maximum limit of 44 mm set by the international standard. Fracture mechanisms found by scanning electron microscopy (SEM) attested the relevance of increasing the fiber content for applications in MASs. The results of stand-alone tests showed that the control (0 vol%) and samples with 20 vol% TVFs absorbed the highest impact energy (Eabs) (212-176 J), and consequently displayed limit velocity (VL) values (213-194 m/s), when compared with 40 vol% fiber composites. However, the macroscopic evaluation found that, referring to the control samples, the plain epoxy shattered completely. In addition, for 10 and 20 vol% TVFs, the composites were fragmented or exhibited delamination fractures, which compromised their physical integrity. On the other hand, composites with 30 and 40 vol% TVFs, whose Eabs and VL varied between 166-130 J and 189-167 m/s, respectively, showed the best physical stability. The SEM images indicated that for composites with 10 and 20 vol% TVFs, the fracture mode was predominantly brittle due to the greater participation of the epoxy resin and the discrete action of the fibers, while for composites with 30 and 40 vol% TVFs, there was activation of more complex mechanisms such as pullout, shearing, and fiber rupture. These results indicate that the TVF composite has great potential for use in bulletproof vests.

Thermal and Colorimetric Parameter Evaluation of Thermally Aged Materials: A Study of Diglycidyl Ether of Bisphenol A/Triethylenetetramine System and Fique Fabric-Reinforced Epoxy Composites.

The main modifications of thermal and colorimetric parameters after thermal aging of DGEBA/TETA system (plain epoxy) and fique-fiber woven fabric-reinforced epoxy composites are described. As a preliminary study, thermal analysis was carried out on epoxy matrix composites reinforced with 15, 30, 40 and 50% fique-fiber woven fabric. After this previous analysis, the 40% composite was chosen to be thermally aged, at 170 °C. Three exposure times were considered, namely, 0, 72, 120 and 240 h. Samples were studied by thermogravimetric analysis (TGA), differential thermal analysis (DTA), differential scanning calorimetry (DSC), thermomechanical analysis (TMA) and colorimetry analysis. Significant color changes were observed after thermal aging combined with oxidation. It was also found that the thermal behavior of the plain epoxy showed greater resistance after thermal exposure. By contrast, the composites were more sensitive to temperature variations as a result of thermal stresses induced between fique fibers and the epoxy matrix.

Nanog, Stat-3, and Sox-5 involvement in human fetal temporomandibular joint late development.

Background and aim: The temporomandibular joint (TMJ) is a synovial joint that allows the complex movements essential for life. It connects the jawbone to the skull, working as a sliding hinge. Moreover, pluripotent stem cells are a source of precursors and tissue-specific cells in developing organisms, however, their biodistribution in developing fetal tissues is weakly studied. The aim of our study was analyse immunohistochemical expression of Nanog, Oct-4, Sox-2 and Stat-3 and Sox-5, in TMJ tissue samples from human fetuses aged between the 12th and 20th weeks of intrauterine life. Materials and methods: We fixed and processed TMJ tissue samples from human fetuses, histological sections and immunohistochemical procedures were carried out. Results: TMJ histological studies examination did not reveal any difference in the tissue organization between the samples in the studied periods. Immunohistochemical analysis demonstrated that Oct-4 and Sox-2 lack their expression in TMJ. In contrast, Nanog was expressed in nucleous of proliferative layer of mandibular condyle, Stat-3 was expressed in nuclear cells of articular disc, Stat-3 and Sox-5 showed positive nuclear and cytoplasmic immunostaining in codrocyte layers and in ossification areas. Conclusions: Nanog acts in maintanence of pluripotency, Stat-3 in articular disc acts as a transcriptional factor. Stat-3 and Sox-2 act in chondrocyte and osteoblast diferentiation. Distribution of the cells, which express Nanog, Stat-3, and Sox-5 in TMJ tissue during fetal development, can help further understand its physiology, pathology, and repairing capacities.

Type I interferon signaling induces a delayed antiproliferative response in Calu-3 cells during SARS-CoV-2 infection.

Meditation practices and their relationship with eating behavior, weight changes, and mental health in adults from different regions of Brazil: A cross-sectional study.

OBJECTIVES: This study aimed to evaluate the effect of different meditation practices on eating behavior, changes in body weight, and mental health. METHODS: A virtual questionnaire was used to evaluate meditation practices and current and prepandemic weights. The questionnaire comprised specific and validated instruments to evaluate body image (silhouette scale), eating behavior (21-item three-factor eating questionnaire), current sleep quality (Pittsburgh Sleep Quality Index), and anxiety (Beck Anxiety Inventory). Initially, data from all the respondents were assessed (n = 764). Mindfulness was the most common type of meditation practice in most Brazilian regions. RESULTS: Lower scores in uncontrolled eating (meditation practitioners = 32.19 ± 19.72 and non-meditation practitioners = 35.17 ± 20.50; P = 0.038) and higher weight loss (meditation practitioners = -0.77 ± 8.44 and non-meditation practitioners = 1.29 ± 6.39; P = 0.013) were observed among those who practiced some type of meditation. To verify the influence of weight, we analyzed the data of individuals who had body mass index ≥25 kg/m²; overweight individuals presented lower uncontrolled eating scores when they practiced meditation. However, no statistical difference was observed between meditation practitioners and non-practitioners when only adequate weight individuals were evaluated. The practice also influenced the perception of body image among men and resulted in lower uncontrolled eating scores on the 21-item three-factor eating questionnaire and greater weight loss during the pandemic among women. Those practicing meditation for >13 mo had a lower final score on the anxiety assessment instrument compared with those practicing for <12 mo (P = 0.002). CONCLUSIONS: The findings indicate that the inclusion of meditation practice as part of the management of overweight may reduce dysfunctional eating behaviors and negative emotions, thereby contributing to weight loss, especially in the long term.

Stromal Ascorbate Peroxidase (OsAPX7) Modulates Drought Stress Tolerance in Rice (Oryza sativa).

Chloroplast ascorbate peroxidases exert an important role in the maintenance of hydrogen peroxide levels in chloroplasts by using ascorbate as the specific electron donor. In this work, we performed a functional study of the stromal APX in rice (OsAPX7) and demonstrated that silencing of OsAPX7 did not impact plant growth, redox state, or photosynthesis parameters. Nevertheless, when subjected to drought stress, silenced plants (APX7i) show a higher capacity to maintain stomata aperture and photosynthesis performance, resulting in a higher tolerance when compared to non-transformed plants. RNA-seq analyses indicate that the silencing of OsAPX7 did not lead to changes in the global expression of genes related to reactive oxygen species metabolism. In addition, the drought-mediated induction of several genes related to the proteasome pathway and the down-regulation of genes related to nitrogen and carotenoid metabolism was impaired in APX7i plants. During drought stress, APX7i showed an up-regulation of genes encoding flavonoid and tyrosine metabolism enzymes and a down-regulation of genes related to phytohormones signal transduction and nicotinate and nicotinamide metabolism. Our results demonstrate that OsAPX7 might be involved in signaling transduction pathways related to drought stress response, contributing to the understanding of the physiological role of chloroplast APX isoforms in rice.

Validation of the Residual Cancer Burden Index as a prognostic tool in women with locally advanced breast cancer treated with neoadjuvant chemotherapy.

AIMS: To correlate the 'Residual Cancer Burden' (RCB) index with overall survival (OS) and disease-free survival (DFS) in women undergoing neoadjuvant chemotherapy at the Cancer Institute of the State of São Paulo. METHODS: We analysed the medical records of patients with breast cancer who underwent neoadjuvant chemotherapy and breast surgery, from 2011 to December 2017. Variables analysed were age, clinical and pathological staging, molecular subtype, number of recurrences or metastases, number of deaths, value and class of the RCB index. We used the Kaplan-Meier and the log-rank statistics to evaluate the possible association between RCB and OS and DFS. A regression model was used to determine the independent association of the RCB with the outcomes controlling for confounding factors. RESULTS: 347 patients were included in the analysis with a mean age of 49.39 years. Initial clinical staging was T3 in 57.9% of patients and 43.8% of patients had N1 axillary status. Survival analysis showed a statistically significant better prognosis for the RCB 0 (pCR) subgroup compared with RCB 1, 2 and 3 (log rank p=0.01). In a multivariate analysis, only the RCB classification showed a statistically significant correlation with DFS (RCB 1, HR 6.9, CI 1.9 to 25.4, p=0.004; RCB 2, HR 4.2, CI 1.6 to 10.8, p=0.03; and RCB 3, HR 7.6, CI 2.76 to 20.8, p=0.00). CONCLUSION: We demonstrated a positive and significant relationship between the RCB index and the risk of relapse and death.

Resultados terapêuticos da homeopatia em pacientes suspeitos ou confirmados de COVID-19: um estudo longitudinal prospectivo / Therapeutic results of homeopathy in suspected or confirmed COVID-19 patients: a longitudinal study

A infecção humana causada pelo vírus SARS-CoV-2 (COVID-19), diagnosticada como pneumonia de causa desconhecida originalmente na cidade de Wuhan (China), foi considerada como pandemia pela Organização Mundial da Saúde. Com a inexistência inicial de uma vacina para proteção dos sadios, foi adotada a estratégia de isolamento social e tratamento com medidas de suporte geral e/ou avançado. Neste contexto, coube investigar a contribuição da terapêutica homeopática no enfrentamento da doença, notadamente no alívio dos sintomas desconfortáveis por ela provocados em sua fase inicial, com acompanhamento e registro dos resultados obtidos pelos médicos homeopatas. MÉTODO: Este estudo coletou, durante o período de maio a setembro de 2020 (após aprovação pelo CEP), informações de pacientes diagnosticados com a doença, tratados por médicos homeopatas com medicamentos homeopáticos escolhidos de acordo com a sintomatologia apresentada pelo paciente. Foram avaliados os efeitos no estado de saúde do paciente, por meio de escores e escalas clínicas, bem como aspectos relacionados à segurança do medicamento, variação na duração da doença e medicamentos mais associados a eventuais sucessos terapêuticos. Questionário padronizado e específico para a COVID-19 foi elaborado e e aplicado para preenchimento dos médicos colaboradores do estudo durante o acompanhamento dos pacientes. Os dados foram armazenados em planilhas eletrônicas e analisados com técnicas estatísticas descritivas e inferenciais. Os pacientes selecionados eram colaboradores do Hospital Santo Antônio - Obras Sociais Irmã Dulce (OSID) e foram submetidos a uma avaliação preliminar presencial no ambulatório de Otorrinolaringologia deste hospital. As consultas homeopáticas foram realizadas por plataforma de Telemedicina para seguimento e acompanhamento do caso. Foram avaliados 116 colaboradores, com faixa etária que variou entre 21 e 66 anos, sendo a média de idade 38 anos; destes, 84 (72%) eram do gênero feminino e 32 (16%) gênero masculino; 53 pacientes (70% dos colaboradores atendidos) eram profissionais da saúde (médicos, enfermeiros e técnicos de enfermagem); 63 (30%) eram colaboradores de áreas administrativas ou técnicas; 50 pacientes tinham critérios para inclusão no grupo de risco (43%). Quanto ao resultado do RT-PCR: 58 pacientes (50%) tiveram RT-PCR detectado (confirmados); 58 pacientes (50%) tiveram RT-PCR não-detectado - destes, 18 pacientes (31%) apresentaram anosmia em sua evolução. Dos 116 pacientes do critério de inclusão, 77 estavam incluídos na síndrome clássica da COVID19. Destes 77 colaboradores, 3 não usaram o medicamento homeopático (N=74). Os medicamentos homeopáticos mais indicados foram: Arsenicum album (42%); Bryonia (24%), Phosphorus (15%); Gelsemium (15%); Pulsatilla (2%); outros (4%). O Score médio de sintomas antes do tratamento foi 12,27 e após o tratamento foi 0,52 (p < xxxxx). Dos 57 pacientes que tiveram anosmia, houve recuperação total em 43 (75%) dos casos no momento da reavaliação. O tempo médio decorrido entre o uso da medicação homeopática e a recuperação dos sintomas foi de 9 dias. Apenas 3 pacientes (3,9%) necessitaram de internamento hospitalar sem necessidade de intubação, sendo 2 deles pertencentes ao grupo de risco. apesar destes resultados serem parciais (pois ainda existem sujeitos da pesquisa ainda em fase de avaliação), os resultados sugerem que o tratamento homeopático promoveu o restabelecimento do quadro infeccioso sem necessidade de internamento em 97% dos pacientes. A anosmia teve recuperação completa em 75% dos pacientes. Arsenicum album, Bryonia e Phosphorus foram os medicamentos predominantemente eleitos para o tratamento, o que corrobora com outros estudos homeopáticos.

The human infection caused by the SARS-CoV-2 virus (COVID-19), originally diagnosed as pneumonia of unknown cause in the city of Wuhan (China), was considered a pandemic by the World Health Organization. With the initial lack of a vaccine to protect healthy people, the strategy relating to social isolation and treatment with general and/or advanced support measures was adopted. In this context, it was necessary to investigate the contribution of homeopathic therapy in coping with the disease, particularly in terms of relieving the uncomfortable symptoms caused by it in its initial phase, with monitoring and recording of the results obtained by homeopathic physicians. METHOD: This study collected information from patients diagnosed with the disease, treated by homeopathic physicians with homeopathic medications chosen according to the symptoms manifested by the patient, from May to September 2020 (after approval by the REC). The effects on the health conditions of patients were assessed using clinical scores and scales, as well as aspects related to the safety of the medication, variations in the duration of the disease and the medications most associated with any therapeutic successes. A standardized questionnaire specific to COVID-19 was drawn up and filled in by the physicians who collaborated in the study during patient monitoring. The data was stored in electronic spreadsheets and analyzed using descriptive and inferential statistical techniques. The selected patients were employees of Hospital Santo Antônio - Obras Sociais Irmã Dulce (OSID) and underwent a preliminary in-person assessment at the otolaryngology outpatient clinic of this hospital. The homeopathic consultations were carried out via a telemedicine platform to follow-up and monitor the case. A total of 116 employees were assessed, ranging in age from 21 to 66, with the average age being 38; of these, 84 (72%) were females and 32 (16%) males; 53 patients (70% of the employees cared for) were health care professionals (physicians, nurses and nursing technicians); 63 (30%) were employees from administrative or technical areas; 50 patients met the criteria for inclusion in the risk group (43%). As for the RT-PCR result: 58 patients (50%) had RT-PCR detected (confirmed); 58 patients (50%) had RT-PCR not detected - of these, 18 patients (31%) had anosmia during their evolution. Of the 116 patients who met the inclusion criteria, 77 were included in the classic COVID-19 syndrome. Of these 77 collaborators, 3 did not use homeopathic medication (N=74). The most indicated homeopathic medications were: Arsenicum album (42%); Bryonia (24%), Phosphorus (15%); Gelsemium (15%); Pulsatilla (2%); others (4%). The average symptom score before treatment was 12.27 and after treatment was 0.52 (p < xxxxx). Of the 57 patients who had anosmia, there was full recovery in 43 (75%) of the cases at the time of reassessment. The average time elapsed between the use of homeopathic medication and the recovery of symptoms was 9 days. Only 3 patients (3.9%) required hospitalization without the need for intubation, 2 of whom belonged to the risk group. Although these results are partial (as there are still research subjects in the evaluation phase), the results suggest that homeopathic treatment promoted the re-establishment of the infectious condition without the need for hospitalization in 97% of the patients. Anosmia recovered completely in 75% of the patients. Arsenicum album, Bryonia and Phosphorus were the drugs predominantly chosen for treatment, which corroborates other homeopathic studies.

Water Immersion Aging of Epoxy Resin and Fique Fabric Composites: Dynamic-Mechanical and Morphological Analysis.

Fiber-reinforced composites are among the most investigated and industrially applied materials. Many studies on these composites using fibers, especially with natural fibers, were made in response to an urgent action for ambient preservation. A particularly relevant situation exists nowadays in the area of materials durability. In this respect, no studies on water-immersion-accelerated aging in fique fiber-epoxy composites are reported. This work aimed to fill this gap by investigating the epoxy matrix composites reinforced with 40 vol% fique fabric. The epoxy matrix and the composite, both unaged and aged, were characterized by weight variation, water absorption, morphology, colorimetry (CIELAB method), Fourier transform infrared spectroscopy (FTIR) and dynamic-mechanical analysis (DMA). The main results were that degradation by water presents appearance of complex microfibril structures, plasticization of epoxy resin, and debonding of the fique fiber/epoxy matrix. The most intense color change was obtained for the water-immersion-aged epoxy by 1440 h. Cole-Cole diagrams revealed the heterogeneity of the materials studied.

Analysis of the Coping Strategies of Primary Health Care Professionals: Cross-Sectional Study in a Large Brazilian Municipality.

Objective: To analyze the coping strategies used by primary healthcare (PHC) professionals. Methods: A cross-sectional, descriptive-analytical study realized with professionals working in primary healthcare units in São José do Rio Preto, a large city in the interior of São Paulo, Brazil. For data collection, we used an instrument developed by the researchers containing sociodemographic and professional variables, as well as the Problem Coping Modes Scale (EMEP). Results: We evaluated 333 PHC professionals. A difference was observed between the scores of the four coping strategies (p < 0.001), with the highest score for the problem-focused strategy (3.8) and the lowest score for the emotion-focused strategy (2.4). Physicians had the lowest scores in coping strategies focused on religious practices/fantastical thinking (p < 0.001) and pursuit of social support (p = 0.045), while community health agents had the highest scores in these coping strategies. Conclusions: Professionals working in PHC have different coping strategies for the problems and stressful situations experienced in the work environment. These strategies can involve more positive attitudes focused on confrontation and problem solving, and on emotional responses that involve attitudes of avoidance and denial of the problem.

Physical and Mechanical Characterization of Titica Vine (Heteropsis flexuosa) Incorporated Epoxy Matrix Composites.

Titica vine (Heteropsis flexuosa) is a typical plant of the Amazon region commonly used for making baskets, bags, brooms and furniture, owing to its stiff fibers. In spite of its interesting properties, there is so far no reported information regarding the use of titica vine fibers (TVFs) in engineering composite materials. In this work, the TVF and its epoxy composites were for the first time physically, thermally and mechanically characterized. Additionally, the effect of two kinds of chemical treatments, one with sodium carbonate and one with calcium lignosulfonate, as well as different volume fractions, 10, 20, 30 and 40 vol%, of TVF-reinforced composites were assessed for corresponding basic properties. The thermogravimetric results of the composites reveal enhanced thermal stability for higher TVF content. In addition, the composite incorporated with 40 vol% of TVFs treated with sodium carbonate absorbed 19% more water than the composites with untreated fibers. By contrast, the calcium lignosulfonate treatment decreased water absorption by 8%. The Charpy and Izod impact tests showed that the composites, incorporated with the highest investigated volume fraction (40 vol%) of TVF, significantly increased the absorbed energy by 18% and 28%, respectively, compared to neat epoxy. ANOVA and Tukey statistical analyses displayed no direct influence of the chemical treatments on the energy absorption of the composites for either impact tests. SEM images revealed the main fracture mechanisms responsible for the performance of TVF composites.

Acitretin mitigates uroporphyrin-induced bone defects in congenital erythropoietic porphyria models.

Congenital erythropoietic porphyria (CEP) is a rare genetic disorder leading to accumulation of uro/coproporphyrin-I in tissues due to inhibition of uroporphyrinogen-III synthase. Clinical manifestations of CEP include bone fragility, severe photosensitivity and photomutilation. Currently there is no specific treatment for CEP, except bone marrow transplantation, and there is an unmet need for treating this orphan disease. Fluorescent porphyrins cause protein aggregation, which led us to hypothesize that uroporphyrin-I accumulation leads to protein aggregation and CEP-related bone phenotype. We developed a zebrafish model that phenocopies features of CEP. As in human patients, uroporphyrin-I accumulated in the bones of zebrafish, leading to impaired bone development. Furthermore, in an osteoblast-like cell line, uroporphyrin-I decreased mineralization, aggregated bone matrix proteins, activated endoplasmic reticulum stress and disrupted autophagy. Using high-throughput drug screening, we identified acitretin, a second-generation retinoid, and showed that it reduced uroporphyrin-I accumulation and its deleterious effects on bones. Our findings provide a new CEP experimental model and a potential repurposed therapeutic.

Evaluation of depression and anxiety symptoms, alcohol consumption, and binge eating in older adults undergoing bariatric surgery: a 6-year follow-up / Avaliação dos sintomas de depressão e ansiedade, consumo de álcool e compulsão alimentar em idosos submetidos à cirurgia bariátrica: seguimento de 6 anos

INTRODUCTION: The literature remains scarce on the late effects of bariatric surgery on the general health of patients who underwent such procedures at an older age. The present study aimed to evaluate depression and anxiety symptoms, risky alcohol consumption, and binge eating in older adults undergoing bariatric surgery. METHODS: This study used current data (from medical records and tests) to conduct a cross-sectional study. A total of 74 individuals aged 60 years and older who underwent bariatric surgery after 55 years of age at a specialist center for obesity management located in Brazil were included and evaluated by the Beck Depression Inventory, Beck Anxiety Inventory, Alcohol Use Disorders Identification Test, and Binge Eating Scale. Demographic and clinical data related to the surgical procedure (weight loss) were also collected. The Cochran-Armitage trend test, Pearson's χ2 test, and a multiple linear regression model were used as needed. A p < 0.05 was considered significant. RESULTS: The individuals were white (65.70%) and women (78.30%), with a mean age of 65.8 (SD 3.90) years. The mean time elapsed from surgery to evaluation was 75.70 (SD 43.70) months; 10.80% of the participants had moderate to severe depression, 8.10% moderate to severe anxiety, and 5.40% risky or high-risk alcohol consumption. None of the participants had binge eating problems. Weight regain was not associated with depressive symptom severity or risky alcohol consumption, but it was significantly associated (p = 0.034) with few or neither anxiety symptoms. Excess weight loss was not associated with any study variable. CONCLUSION: The results show a low prevalence of mental symptoms in older adults undergoing bariatric surgery compared to data from the literature on younger adults undergoing the same procedure.

INTRODUÇÃO: A literatura ainda é escassa sobre os efeitos tardios na saúde geral de pacientes idosos submetidos à cirurgia bariátrica. O presente estudo teve como objetivo avaliar os sintomas de depressão e ansiedade, consumo de álcool de risco e compulsão alimentar em idosos submetidos à cirurgia bariátrica. METODOLOGIA: Este estudo utilizou dados atuais (de prontuários e exames) para realizar um estudo transversal. Um total de 74 indivíduos com 60 anos ou mais que se submeteram à cirurgia bariátrica após os 55 anos em um centro especializado em tratamento da obesidade localizado no Brasil foram incluídos e avaliados pelo Inventário de Depressão e Ansiedade de Beck, Alcohol Use Disorders Identification e Escala de compulsão alimentar. Dados demográficos e clínicos relacionados ao procedimento cirúrgico (perda de peso) também foram coletados. O teste de tendência Cochran-Armitage, o teste do χ2 de Pearson e um modelo de regressão linear múltipla foram usados conforme necessidade. Um p < 0,05 foi considerado significativo. RESULTADOS: Os indivíduos em sua maioria eram brancos (65,70%) e mulheres (78,30%), com média de idade de 65,8 (DP 3,90) anos. O tempo médio decorrido desde a cirurgia até a avaliação foi de 75,70 (DP 43,70) meses; 10,80% dos participantes tinham depressão moderada a grave, 8,10% ansiedade moderada a grave e 5,40% consumo de álcool de risco ou alto risco. Nenhum dos participantes teve problemas de compulsão alimentar. O ganho de peso não foi associado à gravidade dos sintomas depressivos ou consumo de álcool de risco, mas foi significativamente associado (p = 0,034) com poucos ou nenhum sintoma de ansiedade. A perda de excesso de peso não se associou a nenhuma variável do estudo. CONCLUSÕES: Os resultados mostram baixa prevalência de sintomas mentais em idosos submetidos à cirurgia bariátrica em comparação com dados da literatura em adultos jovens submetidos ao mesmo procedimento.

A cirurgia bariátrica como intervenção segura e eficaz para o controle de comorbidades em idosos / Bariatric surgery as a safe and effective intervention for the control of comorbidities in older adults

INTRODUÇÃO: A obesidade no idoso, além de estar associada à piora de doenças relacionadas à síndrome metabólica e a distúrbios osteoarticulares, aumenta o risco de quedas, síndrome de fragilidade, depressão e demência, com consequente perda de funcionalidade. Entre todos os tratamentos disponíveis, a cirurgia bariátrica é uma alternativa em pacientes elegíveis. OBJETIVOS: Discutir aspectos relacionados à segurança e aos benefícios da cirurgia bariátrica para o controle ou a remissão de comorbidades no idoso. METODOLOGIA: Foi realizada revisão de literatura em bases de dados utilizando os seguintes descritores: bariatric surgery and elderly or aged or older adult and comorbidities or safety. Foram incluídos ensaios clínicos, estudos observacionais, estudos comparativos e revisões que avaliaram o efeito da cirurgia bariátrica no controle ou na remissão de comorbidades em idosos. RESULTADOS: Nos últimos anos, vários estudos têm demonstrado não apenas controle ou remissão de comorbidades como diabetes, hipertensão e síndrome da apneia do sono, mas também reduzida taxa de complicações, semelhante à observada em jovens. CONCLUSÕES: Com base nos resultados desses estudos, há espaço para que procedimentos de cirurgia bariátrica sejam indicados a idosos elegíveis, sem limite de idade, considerando também aspectos funcionais e de expectativa de vida.

INTRODUCTION: In addition to being associated with worsening of diseases related to metabolic syndrome and musculoskeletal disorders, obesity in older adults increases the risk of falls, frailty syndrome, depression, and dementia, with consequent functional loss. Among all treatments available, bariatric surgery is an option for eligible patients. OBJECTIVES: To discuss aspects related to the safety and benefits of bariatric surgery for the control or remission of comorbidities in older adults. METHODS: This literature review was carried out in databases, using the following keywords: bariatric surgery and elderly or aged or older adult and comorbidities or safety. We included clinical trials, observational studies, comparative studies, and reviews that evaluated the effect of bariatric surgery on the control or remission of comorbidities in older adults. RESULTS: In recent years, several studies have evidenced not only control or remission of comorbidities, such as diabetes, hypertension, and sleep apnea syndrome, but also a low rate of complications, similar to those observed in young people. CONCLUSIONS: Based on the results of these studies, bariatric surgical procedures can be indicated for eligible older adults, without age restriction, taking into account functional and life expectancy aspects.

Soul care in the hospital nursing context: an analysis based on Transpersonal Caring.

OBJECTIVE: To unveil spirituality in the care process of nursing professionals in the hospital context under the lens of Transpersonal Caring. METHOD: A descriptive-exploratory study implementing a qualitative approach conducted with professionals from the nursing team in a general hospital in Bahia, using a semi-structured interview submitted to the content analysis technique and analyzed from the perspective of the Theory of Transpersonal Caring theoretical framework. RESULTS: There were 16 professionals who participated. It was found that the nursing team perceives the patient and family's demand for spiritual care, and sometimes even has experiences and suggestions for interventions, especially those which cultivate faith and spirituality, but this does not happen with most of these professionals who demonstrate difficulties, unpreparedness and fear of taking on such care responsibility. CONCLUSION: There is a need to develop better interaction/spiritual care skills by nursing professionals in the challenging context of the search for meaning, faith and hope mobilized by the disease experience. The Systematization of Spiritual Nursing Care and Transpersonal Caring stand out as appropriate devices, which provide consistent subsidies for undertaking spiritual care.
