RESUMO

A Doença Renal Crônica (DRC) é uma importante redução da função renal que causa alterações no metabolismo dos indivíduos. Para acompanhar a progressão da DRC e prevenir possíveis complicações, foi realizada uma pesquisa para avaliar o perfil sociodemográfico, bioquímico e hematológico de pacientes com Insuficiência Renal Crônica (IRC) submetidos a hemodiálise. Esta pesquisa foi quantitativa, descritiva e transversal de caráter retrospectivo, realizada por meio da análise de dados secundários contidos nos prontuários dos pacientes. A coleta de dados ocorreu no Centro de Hemodiálise da cidade de Russas, no Ceará. A amostra foi constituída por 161 pacientes com DRC, sendo 63,35% do sexo masculino e 85,71% pardos, com uma idade média de 54,39 anos. Desses, 63,97% tinham entre 2 e 10 anos de tratamento e 57,76% possuíam ensino fundamental incompleto. 19,25% residiam em Russas. Resultados: Após a hemodiálise, os resultados mostraram 44 mg/dL de Ureia, 48,44% dos pacientes com valores normais. A hemoglobina e hematócrito médios foram 11,8 g/dL e 33,7%, respectivamente, sendo que 63,35% tiveram valores reduzidos. 85,10% dos pacientes tiveram contagem de plaquetas normal, 72,04% níveis adequados de ferro e albumina, 52,79% tiveram níveis elevados de ferritina, 23,61% redução de transferrina e níveis lipídicos satisfatórios. 79,50% apresentaram níveis séricos de potássio dentro da normalidade, 12,42% de fósforo acima do normal, 85,09% de cálcio dentro dos valores normais, 39,13% de PTHi normais e 86,33% de glicose dentro dos valores considerados normais. Com base nos resultados, concluiu-se que todos os pacientes em tratamento hemodialítico apresentam diversas alterações em decorrência da DRC e do próprio processo de tratamento. Portanto, a realização de exames para avaliar ou monitorar possíveis complicações da IRC é essencial para criar estratégias e intervenções mais eficazes, que melhorem a assistência prestada a esses pacientes e, consequentemente, da qualidade e expectativa de vida dos mesmos.


Chronic Kidney Disease (CKD) is an important reduction in kidney function that causes changes in the metabolism of individuals. To monitor the progression of CKD and prevent possible complications, a survey was carried out to assess the sociodemographic, biochemical and hematological profile of patients with Chronic Renal Failure (CRF) undergoing hemodialysis. This research was quantitative, descriptive and cross-sectional with a retrospective character, carried out through the analysis of secondary data contained in the patients' medical records. Data collection took place at the Hemodialysis Center in the city of Russas, Ceará. The sample consisted of 161 patients with CKD, 63.35% male and 85.71% brown, with an average age of 54.39 years. Of these, 63.97% had between 2 and 10 years of treatment and 57.76% had incomplete primary education. 19.25% resided in Russas. Results: After hemodialysis, the results showed 44 mg/dL of Urea, 48.44% of patients with normal values. Average hemoglobin and hematocrit were 11.8 g/dL and 33.7%, respectively, with 63.35% having reduced values. 85.10% of the patients had normal platelet counts, 72.04% had adequate levels of iron and albumin, 52.79% had high levels of ferritin, 23.61% had reduced transferrin and satisfactory lipid levels. 79.50% had serum levels of potassium within the normal range, 12.42% of phosphorus above normal, 85.09% of calcium within normal values, 39.13% of PTHi normal and 86.33% of glucose within the values considered normal. Based on the results, it was concluded that all patients on hemodialysis have several changes due to CKD and the treatment process itself. Therefore, carrying out tests to assess or monitor possible complications of CRF is essential to create more effective strategies and interventions that improve the care provided to these patients and, consequently, their quality and life expectancy.


La Enfermedad Renal Crónica (ERC) es una reducción importante de la función renal que provoca cambios en el metabolismo de los individuos. Para monitorizar la evolución de la ERC y prevenir posibles complicaciones, se realizó una encuesta para evaluar el perfil sociodemográfico, bioquímico y hematológico de los pacientes con Insuficiencia Renal Crónica (IRC) en hemodiálisis. Esta investigación fue cuantitativa, descriptiva y transversal con carácter retrospectivo, realizada a través del análisis de datos secundarios contenidos en las historias clínicas de los pacientes. La recolección de datos ocurrió en el Centro de Hemodiálisis de la ciudad de Russas, Ceará. La muestra estuvo constituida por 161 pacientes con ERC, 63,35% del sexo masculino y 85,71% pardos, con una edad media de 54,39 años. De estos, 63,97% tenían entre 2 y 10 años de tratamiento y 57,76% tenían primaria incompleta. El 19,25% residía en Russas. Resultados: Posterior a la hemodiálisis los resultados arrojaron 44 mg/dL de Urea, 48,44% de los pacientes con valores normales. La hemoglobina y el hematocrito medios fueron 11,8 g/dl y 33,7 %, respectivamente, con un 63,35 % con valores reducidos. El 85,10% de los pacientes presentaba plaquetas normales, el 72,04% presentaba niveles adecuados de hierro y albúmina, el 52,79% presentaba niveles elevados de ferritina, el 23,61% presentaba transferrina reducida y niveles satisfactorios de lípidos. El 79,50% presentaba niveles séricos de potasio dentro de la normalidad, el 12,42% de fósforo por encima de lo normal, el 85,09% de calcio dentro de los valores normales, el 39,13% de PTHi normal y el 86,33% de glucosa dentro de los valores considerados normales. Con base en los resultados, se concluyó que todos los pacientes en hemodiálisis tienen varios cambios debido a la ERC y al propio proceso de tratamiento. Por tanto, la realización de pruebas para evaluar o monitorizar las posibles complicaciones de la IRC es fundamental para crear estrategias e intervenciones más eficaces que mejoren la atención a estos pacientes y, en consecuencia, su calidad y esperanza de vida.

RESUMO

Abstract Objective: to evaluate the effect of nursing home care interventions on the quality of life in family caregivers of aged stroke survivors. Method: a Randomized Clinical Trial, blinded for outcome evaluation. Forty-eighty family caregivers of aged stroke survivors participated in the study. The Intervention Group received three home visits by nurses one month after hospital discharge to provide stroke-related education (i.e., how to access health services and perform care activities) and emotional support. The Control Group received the usual guidance from the health services. Quality of life was assessed using the World Health Organization Quality of Life Assessment (WHOQOL-BREF) instrument and the Old Module(WHOQOL-OLD) 1 week, 2 months, and 1 year after discharge. Results: the caregivers were mainly women, children, or spouses. The caregivers in the Intervention Group and Control Group did not significantly differ in terms of their Overall Quality of Life at baseline. There was no interaction effect between group allocation and Overall Quality of Life(p=0.625) over time. However, there was an interaction effect for Social Relations(p=0.019) and Autonomy (p=0.004). Conclusion: the intervention exerted a statistically significant effect on the quality of life of family caregivers with respect to social relationships and autonomy. Trial registration: NCT02807012.


Resumo Objetivo: avaliar o efeito de intervenção educativa domiciliar de enfermagem na qualidade de vida de cuidadores familiares de idosos sobreviventes de acidente vascular cerebral (AVC). Método: Ensaio Clínico Randomizado, cego para avaliação de resultados. Quarenta e oito cuidadores familiares de idosos sobreviventes de AVC participaram do estudo. O Grupo de Intervenção recebeu três visitas domiciliares de enfermeiros, um mês após a alta hospitalar, para fornecer educação relacionada ao AVC (como acessar os serviços de saúde e realizar atividades de cuidado) e apoio emocional. O Grupo Controle recebeu as orientações habituais dos serviços de saúde. A qualidade de vida foi avaliada usando o instrumento Avaliação da Qualidade de Vida da Organização Mundial da Saúde (WHOQOL-BREF) e o Módulo Old (WHOQOL-OLD) em 1 semana, 2 meses e 1 ano após a alta. Resultados: os cuidadores eram principalmente mulheres, filhos ou cônjuges. Os cuidadores do Grupo Intervenção e do Grupo Controle não diferiram significativamente em termos de Qualidade de Vida Geral no início do estudo. Não houve efeito de interação entre a alocação do grupo e a Qualidade de Vida Geral (p=0,625) ao longo do tempo. No entanto, houve efeito de interação para Relações Sociais (p=0,019) e Autonomia (p=0,004). Conclusão: a intervenção apresentou efeito estatisticamente significativo na qualidade de vida dos cuidadores familiares no que diz respeito às relações sociais e autonomia.

RESUMO

Abstract Objective: to identify the sociodemographic profile and the characteristics of interpersonal violence against older adults during the first year of the COVID-19 pandemic in a capital city from the Brazilian Southeast region. Method: a descriptive and exploratory research study with a cross-sectional design based on the notifications of suspected or confirmed cases of violence against older adults between March 2020 and March 2021. A univariate statistical analysis and Fisher's exact test (p<0.05) were performed. Results: a total of 2,681 notifications were recorded during the period. The main victims were individuals aged between 60 and 64 years old, female, white-skinned and with low schooling levels. The instances of violence were more frequent in the victims' homes. Physical and psychological violence predominated, through physical force/beatings and threats, respectively. Most of the aggressors were male, younger than the victims and generally their children or intimate partners. The aggressions were perpetrated more than once and were driven by generational conflicts. There was low referral to entities for the protection of older adults. Conclusion: the sociodemographic profile found evidences vulnerable victims, subjected to many types of violence, and at a potential risk against their overall health.

RESUMO

Abstract Objective: the purpose of this pre-feasibility study was to examine perceptions and experiences of a Sit-to-stand activity with urban Brazilian community-dwelling older people in their homes. Method: the exploration method was focused ethnography. Purposive sampling was used to recruit 20 older people. Five means of data generation were used, namely: socio-demographic surveys, participant observations, informal interviews, formal semi-structured interviews, and field notes. Data analysis was qualitative content analysis. Results: the experience of mobility-challenged older people with the Sit-to-stand activity was dependent on their mobility expectations involving many factors that worked together to influence their beliefs and attitudes towards the activity, preferences, behaviors, and cultural perceptions. The participants of this study seemed to find the activity enjoyable; however, the most noticeable shortcomings for their engagement in the Sit-to-stand activity emerged as gaps in their personal and intrapersonal needs. Conclusion: the recommendations generated from the study findings call for the design of implementation strategies for the Sit-to-stand intervention that are tailored to this particular population's needs.


Resumo Objetivo: o objetivo deste estudo de pré-viabilidade foi examinar percepções e experiências da atividade de Sit-to-stand com idosos brasileiros residentes em suas casas, no meio urbano. Método: o método exploratório foi etnografia focada. Foi utilizada a amostragem intencional para recrutar 20 idosos. Foram utilizados cinco meios de geração de dados: inquéritos sociodemográficos, observações participantes, entrevistas informais, entrevistas formais semiestruturadas e notas de campo. Os dados foram analisados mediante análise de conteúdo qualitativo. Resultados: a experiência dos idosos com problemas de mobilidade na realização da atividade Sit-to-stand dependia de suas expectativas de mobilidade envolvendo muitos fatores coordenados que, de forma conjunta, influenciaram suas crenças e atitudes em relação à atividade, suas preferências, seus comportamentos e percepções culturais. Os participantes deste estudo pareciam considerar a atividade aprazível; no entanto, as deficiências mais perceptíveis para o engajamento dos participantes na atividade Sit-to-stand surgiram de falhas em suas necessidades pessoais e intrapessoais. Conclusão: as recomendações geradas a partir dos achados do estudo convocam a concepção de estratégias de implementação da intervenção Sit-to-stand adaptadas às necessidades dessa população em particular.

RESUMO

Objetivo: investigar los factores que influyen en la alfabetización en salud de los pacientes con enfermedad arterial coronaria. Método: estudio transversal, que incluyó 122 pacientes con enfermedades coronarias (60,7% del sexo masculino; 62,07±8,8 años); se evaluó la alfabetización en salud y el conocimiento específico sobre la enfermedad mediante entrevistas con los participantes, utilizando el Short Test of Functional Health Literacy in Adults e Short version of the coronary artery disease education questionnaire. Los datos fueron descritos por medidas de tendencia central y frecuencias. Los factores que influyen en la alfabetización en salud se determinaron mediante un modelo de regresión lineal. El nivel de significación adoptado fue del 5%. El estudio fue aprobado por el Comité de Ética e Investigación. Resultados: la edad y la hipertensión mostraron una relación inversa y significativa con la alfabetización en salud. Por otro lado, un mayor nivel educativo y tener empleo se asociaron con puntajes más altos en el instrumento de alfabetización en salud. El conocimiento específico sobre la enfermedad no influyó en la alfabetización en salud. Las variables del modelo de regresión explicaron el 55,3% de alfabetización inadecuada. Conclusión: en el presente estudio, se concluyó que el conocimiento sobre la enfermedad no influye en la alfabetización en salud, pero los profesionales deben considerar los factores sociodemográficos y clínicos para planificar las intervenciones.


Objective: to investigate the factors that exert an influence on health literacy in patients with coronary artery disease. Methods: a crosssectional study, including 122 patients with coronary diseases (60.7% male; 62.07 ± 8.8 years old). Health literacy and specific knowledge about the disease were evaluated through interviews with the participants by means of the Short Test of Functional Health Literacy in Adults and the Short version of the coronary artery disease education questionnaire. The data were described by means of central tendency measures and frequencies. The factors that exert an influence on health literacy were determined by means of a linear regression model. The significance level adopted was 5%. The study was approved by the Research Ethics Committee. Results: age and arterial hypertension presented an inverse and significant relationship with health literacy. On the other hand, higher schooling levels and having a job were associated with better scores in the health literacy instrument. Specific knowledge about the disease did not exert any influence on health literacy. The variables included in the regression model explained 55.3% of inadequate literacy. Conclusion: this study, knowledge about the disease exerts no influence on health literacy: however, the professionals should consider the sociodemographic and clinical factors to plan the interventions.

Método: estudo transversal, incluindo 122 pacientes com coronariopatias (60,7% do sexo masculino; 62,07±8,8 anos); letramento em saúde e conhecimento específico da doença foram avaliados por meio de entrevista com os participantes, pelo Short Test of Functional Health Literacy in Adults e Short version of the coronary artery disease education questionnaire. Os dados foram descritos por medidas de tendência central e frequências. Fatores que influenciam o letramento em saúde foram determinados por modelo de regressão linear. O nível de significância adotado foi de 5%. O estudo foi aprovado pelo Comitê de Ética e Pesquisa. Resultados: idade e hipertensão apresentaram uma relação inversa e significativa com letramento em saúde. Por outro lado, maior escolaridade e estar empregado associaram-se com maiores pontuações no instrumento de letramento em saúde. O conhecimento específico da doença não influenciou o letramento em saúde. As variáveis do modelo de regressão explicaram 55,3% do letramento inadequado. Conclusão: no presente estudo o conhecimento sobre a doença não influência o letramento em saúde, mas os profissionais devem considerar os fatores sociodemográficos e clínicos para planejar as intervenções.

RESUMO

OBJECTIVE: The aim of this study was to investigate health-related quality of life (HRQoL) before and 1 year after radical cystectomy in relation to age and gender. METHODS: This prospective study involves 112 men and 40 women with bladder cancer treated with radical cystectomy between 2015 and 2018. HRQoL was assessed preoperatively and 1 year post-surgery through Functional Assessment of Cancer Therapy Scale - General (FACT-G) and Functional Assessment of Cancer Therapy Scale - Vanderbilt Cystectomy Index (FACT-VCI) questionnaires. The median age of the 152 patients was 71.5 years. RESULTS: Preoperatively, emotional and functional well-being were negatively affected. Physical, emotional and functional well-being presented higher values 1 year after surgery compared to before radical cystectomy, that is, better HRQoL. Social well-being showed a reduction, especially regarding closeness to partner and support from family. Men and women were equally satisfied with their sex life before radical cystectomy, but less so 1 year after, where men were less satisfied compared to women. Additionally, one out of five patients reported that they had to limit their physical activities, were afraid of being far from a toilet and were dissatisfied with their body appearance after surgery. CONCLUSIONS: Recovery regarding HRQoL was ongoing 1 year after radical cystectomy. Patients recovered in three out of four dimensions of HRQoL, but social well-being was still negatively affected 1 year after treatment. Sexual function after radical cystectomy was exceedingly limited for both men and women. An individual sexual rehabilitation plan involving the couple with special intention to encourage intimacy, might not only improve sexual life but also have a positive effect on social well-being as a consequence.

RESUMO

Sarcopenia has a high prevalence among the aging population. Sarcopenia is of tremendous socioeconomic importance because it can lead to falls and hospitalization, subsequently increasing healthcare costs while limiting quality of life. In sarcopenic muscle fibers, the E3 ubiquitin ligase F-Box Protein 32 (Fbxo32) is expressed at substantially higher levels, driving ubiquitin-proteasomal muscle protein degradation. As one of the key regulators of muscular equilibrium, the transcription factor Forkhead Box O3 (FOXO3) can increase the expression of Fbxo32, making it a possible target for the regulation of this detrimental pathway. To test this hypothesis, murine C2C12 myoblasts were transduced with AAVs carrying a plasmid for four specific siRNAs against Foxo3. Successfully transduced myoblasts were selected via FACS cell sorting to establish single clone cell lines. Sorted myoblasts were further differentiated into myotubes and stained for myosin heavy chain (MHC) by immunofluorescence. The resulting area was calculated. Myotube contractions were induced by electrical stimulation and quantified. We found an increased Foxo3 expression in satellite cells in human skeletal muscle and an age-related increase in Foxo3 expression in older mice in silico. We established an in vitro AAV-mediated FOXO3 knockdown on protein level. Surprisingly, the myotubes with FOXO3 knockdown displayed a smaller myotube size and a lower number of nuclei per myotube compared to the control myotubes (AAV-transduced with a functionless control plasmid). During differentiation, a lower level of FOXO3 reduced the expression Fbxo32 within the first three days. Moreover, the expression of Myod1 and Myog via ATM and Tp53 was reduced. Functionally, the Foxo3 knockdown myotubes showed a higher contraction duration and time to peak. Early Foxo3 knockdown seems to terminate the initiation of differentiation due to lack of Myod1 expression, and mediates the inhibition of Myog. Subsequently, the myotube size is reduced and the excitability to electrical stimulation is altered.

RESUMO

To analyze the prognostic value of fibrinogen-albumin ratio (FAR) in predicting the overall survival in elderly osteosarcoma patients. One hundred nineteen elderly osteosarcoma patients (> 40 years old) from 2 centers were retrospectively reviewed and analyzed. The cutoff values of the biomarker were calculated via receiver operating characteristic curves, and the cohort was divided into high FAR group and low FAR group. The association between the FAR and clinical-pathological parameters was analyzed. And the prognosis of elderly osteosarcoma patients and the potential risk factors were analyzed using Kaplan-Meier method and Cox proportional hazards model. Finally, a clinical nomogram was constructed, and its predictive capacity was verified. According to receiver operating characteristic results, the cutoff value for FAR was 0.098, and the enrolled patients were divided into the low FAR group and high FAR group. The FAR was significantly correlated with several clinical-pathological characteristics, including age, tumor size, tumor stage, recurrence, and metastasis. Moreover, the multivariate Cox analyses results showed that the FAR, pathological fracture, and metastasis were independent risk factors for overall survival in elderly osteosarcoma patients. The predictive nomogram was subsequently constructed, representing satisfactory predictive performance for prognosis in elderly patients with osteosarcoma. The FAR value is a promising indicator for elderly osteosarcoma patients, which is correlated with the various clinical characteristics and prognosis. A clinical nomogram integrating FAR and other clinical indicators is a convenient and available tool to assess the prognosis and manage the individualized and precise treatment of elderly patients with osteosarcoma.

RESUMO

OBJECTIVE: Depression in patients undergoing coronary artery graft bypass (CABG) surgery is associated with morbidity and mortality, making its early identification and clinical management crucial. Vasculopathy and older age, hallmarks of patients requiring CABG, are also features of vascular depression. In this study, we assess for features of vascular depression in patients undergoing CABG surgery. METHODS: This is a cross-sectional analysis of a single-site prospective observational cohort study of patients undergoing CABG surgery. Subjects were assessed preoperatively using the Depression Interview and Structured Hamilton (DISH), depression scales, transcranial Doppler, neuropsychological testing, and clinical dementia rating (CDR). RESULTS: Of 161 subjects (mean age 66.2 ± 9.3, female 25%) who completed DISH, 18 had major or minor depression, 17 of whom had a past history of major or minor depression (mean age of onset 35.8 years-old). Pre-CABG depression was associated with greater functional impairment on CDR Sum of Boxes (OR = 3.7, 95% CI: 1.4, 9.7) and worse performance on letter fluency test (OR = 0.90, 95% CI: 0.81, 0.99) and trail-making tests (A: OR = 1.06, 95% CI: 1.01, 1.12; B: OR 1.02, 95% CI: 1.01, 1.04). Pre-CABG depression was not associated with middle cerebral artery (MCA) stenosis. CONCLUSIONS: Pre-CABG depression is associated with cognitive and functional impairment similar to vascular depression, but we did not find evidence of an association with older age of onset and MCA stenosis. Further studies on white matter disease in this population are needed to examine the vascular depression hypothesis for pre-CABG depression.

RESUMO

Neovascular age-related macular degeneration (nAMD), along with its clinical subtype known as polypoidal choroidal vasculopathy (PCV), are among the leading causes of vision loss in elderly Asians. In a genome-wide association study (GWAS) comprising 3,128 nAMD (1,555 PCV and 1,573 typical nAMD), and 5,493 controls of East Asian ancestry, we identify twelve loci, of which four are novel ([Formula: see text]). Substantial genetic sharing between PCV and typical nAMD is noted (rg = 0.666), whereas collagen extracellular matrix and fibrosis-related pathways are more pronounced for PCV. Whole-exome sequencing in 259 PCV patients revealed functional rare variants burden in collagen type I alpha 1 chain gene (COL1A1; [Formula: see text]) and potential enrichment of functional rare mutations at AMD-associated loci. At the GATA binding protein 5 (GATA5) locus, the most significant GWAS novel loci, the expressions of genes including laminin subunit alpha 5 (Lama5), mitochondrial ribosome associated GTPase 2 (Mtg2), and collagen type IX alpha 3 chain (Col9A3), are significantly induced during retinal angiogenesis and subretinal fibrosis in murine models. Furthermore, retinoic acid increased the expression of LAMA5 and MTG2 in vitro. Taken together, our data provide insights into the genetic basis of AMD pathogenesis in the Asian population.

RESUMO

BACKGROUND: Resilience is the capacity for physical and emotional recovery from stressful events like cancer diagnosis and treatment. OBJECTIVES: The objectives of this study were to review existing literature to understand and illustrate ways to assess and manage resilience when providing holistic care to older adults with cancer. METHODS: A review of the literature was conducted with a focus on assessment, management, and preservation of resilience in older adults with cancer. FINDINGS: Interventions to support resilience include managing problems that occur in the areas of nutrition, exercise, social support, cognition, functional status, and emotion. Cell cycle arrest using pharmacologic agents may provide a novel proactive approach to protect resilience from deteriorating during chemotherapy to treat cancer. The oncology nurse can assess and manage resilience. which can lead to better treatment outcomes.

RESUMO

OBJECTIVES: First, to examine 7 large Medicare Advantage (MA) plans' use of step therapy. Second, to compare step therapy that health plans imposed in their MA and commercial (employer) drug coverage policies. STUDY DESIGN: Database analysis. METHODS: Using data from the Tufts Medical Center Specialty Drug Evidence and Coverage Database, we evaluated 7 large MA plans' use of step therapy in their Part B drug coverage policies. First, we determined the frequency with which different MA plans applied step therapy. Second, we determined the frequency with which plans imposed step therapy protocols across International Classification of Diseases, Tenth Revision, Clinical Modification categories. Third, we compared each step therapy protocol against each drug's corresponding FDA label indication. Fourth, we examined the consistency of step therapy protocols between the same insurer's MA and commercial lines of business. RESULTS: The frequency with which the included MA plans imposed step therapy ranged from 26.1% to 63.7%. Step therapy was most common for dermatology conditions (90.2%) and least common for oncology conditions (28.6%). On average, MA plans' step therapy requirements were consistent with the drug's FDA label indication 29.0% of the time. MA plans' and commercial plans' use of step therapy differed for the same drug-indication pairs 46.1% of the time. CONCLUSIONS: MA plans vary in the frequency with which they impose step therapy protocols in their Part B drug coverage policies. Moreover, insurers often impose different step therapy protocols in their MA plan and commercial plan offerings. Differences in plans' step therapy requirements may result in variability in patients' access to care within MA.

RESUMO

OBJECTIVES: To determine agreement between variables capturing the primary payer at cancer diagnosis across the Pennsylvania Cancer Registry (PCR) and statewide facility discharge records (Pennsylvania Health Care Cost Containment Council [PHC4]) for adults younger than 65 years, and to specifically examine factors associated with misclassification of Medicaid status in the registry given the role of managed care. STUDY DESIGN: Cross-sectional analysis of the primary cancer cases among adults aged 21 to 64 years in the PCR from 2010 to 2016 linked to the PHC4 facility visit records. METHODS: We assessed agreement of payer at diagnosis (Medicare, Medicaid, private, other, uninsured, unknown) across data sources, including positive predictive value (PPV) and sensitivity, using the PHC4 records as the gold standard. The probability of misclassifying Medicaid in registry was estimated using multivariate logit models. RESULTS: Agreement of payers was high for private insurance (PPV, 89.7%; sensitivity, 83.6%), but there was misclassification and/or underreporting of Medicaid in the registry (PPV, 80%; sensitivity, 58%). Among cases with "other" and "unknown" insurance, 73.8% and 62.1%, respectively, had private insurance according to the PHC4 records. Medicaid managed care was associated with a statistically significant increase of 12.6 percentage points (95% CI, 9.4-15.8) in the probability of misclassifying Medicaid enrollment as private insurance in the registry. CONCLUSIONS: Findings suggest caution in conducting and interpreting research using insurance variables in cancer registries.

RESUMO

A patient in her 90s with rheumatoid arthritis was admitted to the hospital. She was brought to the emergency department with a complaint of a fever and diagnosed with a urinary tract infection on admission, and antimicrobial therapy was started. On day 8 of admission, abdominal ultrasonography revealed a right subphrenic abscess due to cholecystitis with perforation. The patient consulted with the Department of Surgery, but drainage was deemed difficult due to the anatomical location of the gallbladder, and conservative treatment with antibiotics was continued. After two months of intravenous antimicrobial therapy, the abscess shrank, and the patient was discharged from the hospital after switching to oral antimicrobial therapy. At a follow-up visit two weeks after discharge, the abscess was confirmed to have disappeared, the oral antimicrobial therapy was discontinued, with no abscess recurrence noted. The principle of treatment for subphrenic abscess is the administration of broad-spectrum antimicrobial agents that cover enterobacteria and anaerobes, and drainage at appropriate times. Indeed, drainage is performed in most of the reported cases of subphrenic abscesses. However, in very elderly patients or those in whom puncture is difficult, conservative treatment while carefully checking imaging findings and other potentially involved factors may be an option.

RESUMO

An 81-year-old man was being treated with oral medication for chronic heart failure and epilepsy. He had no history of diabetes, cirrhosis, or gastric surgery. He was admitted to our hospital due to disturbance of consciousness. His blood glucose level was 6 mg/dl, with a relatively high insulin level (14.4 µU/ml). Computed tomography and a 48 h fasting test showed no signs of insulinoma. There were no signs of reactive hypoglycemia, insulin autoimmune syndrome, or adrenal insufficiency. His wife had been taking medication for diabetes, including sulfonylurea. She had dementia, and he managed her medication. Since his medication was found in his wife's medicine box, we considered the possibility that he might have taken sulfonylurea by mistake. We asked his daughter to manage their medicine. However, one month later, he was admitted to our hospital again with severe hypoglycemia. His wife's HbA1c value and estimated glomerular filtration rate were 6.9% and 30 ml/min/1.73 m2. We asked his wife's home doctor to stop sulfonylurea prescription, and the hypoglycemia did not recur, with his wife's level of HbA1c remaining stable.Elderly individuals and patients with an impaired renal function are prone to hypoglycemia from sulfonylurea. In elderly households, there is a possibility of accidental ingestion of oral hypoglycemic agents by other family members living with the patient. It is therefore necessary to understand and manage the medications of family members living together. It is also important to avoid prescribing medications with a high risk of hypoglycemia to elderly patients.

RESUMO

OBJECTIVE: With socioeconomic development, improvement in preventing and curing infectious diseases, and increased exposure to non-communicable diseases (NCDs) risk factors (eg, overweight/obesity, sedentary lifestyle), the majority of adult deaths in Bangladesh in recent years are due to NCDs. This study examines trends in cause-specific mortality risks using data from the Matlab Health and Demographic Surveillance System (HDSS). DESIGN, SETTINGS AND PARTICIPANTS: We conducted a follow-up study from 2003 to 2017 using data from Matlab HDSS, which covers a rural population of 0.24 million (in 2018) in Chandpur, Bangladesh. HDSS assessed the causes of all deaths using verbal autopsy and classified the causes using the 10th revision of the International Statistical Classification of Diseases. We examined 19 327 deaths involving 2 279 237 person-years. METHODS: We calculated annual cause-specific mortality rates and estimated adjusted proportional HRs using a Cox proportional hazards model. RESULTS: All-cause mortality risk declined over the study period among people aged 15 and older, but the risk from stroke increased, and from heart disease and cancers remained unchanged. These causes were more common among middle-aged and older people and thus bore the most burden. Mortality from causes other than NCDs-namely, infectious and respiratory diseases, injuries, endocrine disorders and others-declined yet still constituted over 30% of all deaths. Thus, the overall mortality decline was associated with the decline of causes other than NCDs. Mortality risk sharply increased with age. Men had higher mortality than women from heart disease, cancers and other causes, but not from stroke. Lower household wealth quintile people have higher mortality than higher household wealth quintile people, non-Muslims than Muslims. CONCLUSION: Deaths from stroke, heart disease and cancers were either on the rise or remained unchanged, but other causes declined continuously from 2003 to 2017. Immediate strengthening of the preventive and curative healthcare systems for NCDs management is a burning need.

RESUMO

Nonalcoholic fatty liver disease (NAFLD) is associated with mitochondrial damage. Circulating mitochondrial metabolites may be elevated in NAFLD but their associations with liver damage is not known. This study aimed to assess the association of key mitochondrial metabolites with the degree of liver fibrosis in the context of NAFLD and nonalcoholic steatohepatitis (NASH). Cross-sectional analyses were performed on two cohorts of biopsy-proven NAFLD and/or NASH subjects. The association of circulating mitochondrial metabolite concentrations with liver fibrosis was assessed using linear regression analysis. In the single-center cohort of NAFLD subjects (n = 187), the mean age was 54.9 ±13.0 years, 40.1% were female and 86.1% were White. Type 2 diabetes (51.3%), hypertension (43.9%) and obesity (72.2%) were prevalent. Those with high citrate had a higher proportion of moderate/significant liver fibrosis (stage F ≥ 2) (68.4 vs. 39.6%, p = 0.001) and advanced fibrosis (stage F ≥ 3) (31.6 vs. 13.6%, p = 0.01). Citrate was associated with liver fibrosis independent of age, sex, NAFLD activity score and metabolic syndrome (per 1 SD increase: ß = 0.19, 95% CI: 0.03-0.35, p = 0.02). This association was also observed in a cohort of NASH subjects (n = 176) (ß = 0.21, 95% CI: 0.07-0.36, p = 0.005). The association of citrate with liver fibrosis was observed in males (p = 0.005) but not females (p = 0.41). In conclusion, circulating citrate is elevated and associated with liver fibrosis, particularly in male subjects with NAFLD and NASH. Mitochondrial function may be a target to consider for reducing the progression of liver fibrosis and NASH.

RESUMO

Thymalin is an immunomodulatory drug containing a polypeptide extract of thymus that has demonstrated efficacy in the therapy of acute respiratory distress syndrome and chronic obstructive pulmonary disease, as well as in complex therapy related to severe COVID-19 in middle-aged and elderly patients.. KE and EW dipeptides are active substances of Thymalin. There is evidence that KE stimulates cellular immunity and nonspecific resistance in organisms, exerting an activating effect on macrophages, blood lymphocytes, thymocytes, and neutrophils, while EW reduces angiotensin-induced vasoconstriction and preserves endothelium-dependent vascular relaxation by inhibiting ACE2, the target protein of SARS-CoV-2. However, the mechanism of the immunomodulatory action of Thymalin, KE, and EW during COVID-19 remains unclear. To identify the potential mechanism of action underlying the immunomodulatory activity of Thymalin and its active components, EW and KE dipeptides, we assessed inflammatory response in the context of COVID-19. Interactions between EW and KE dipeptides and double-stranded DNA (dsDNA) were investigated by molecular modeling and docking using ICM-Pro. Analysis of the possible effect of EW and KE dipeptides on gene expression and protein synthesis involved in the pathogenesis of COVID-19 was conducted through the use of bioinformatics methods, including a search for promoter sequences in the Eukaryotic Promoter Database, the determination of genes associated with the development of COVID-19 using the PathCards database of human biological pathways (pathway unification database), identification of the relationship between proteins through cluster analysis in the STRING database ('Search Tool for Retrieval of Interacting Genes/Proteins'), and assessment of the functional enrichment of protein-protein interaction (PPI) using the terms of gene ontology (GO) and the Markov cluster algorithm (MCL). After that, in vitro studying of a lipopolysaccharide (LPS)-induced model of inflammation using human peripheral blood mononuclear cells was performed. ELISA was applied to assess the level of cytokines (IL-1ß, IL-6, TNFα) in the supernatant of cells with or without the impact of EW and KE peptides. Blood samples were obtained from four donors; for each cytokine, ELISA was performed 2-4 times, with two parallel experimental or control samples for each experiment (experiments to assess the effects of peptides on LPS-stimulated cells were repeated four times, while additional experiments with unstimulated cells were performed two times). Using molecular docking, GGAG was found to be the best dsDNA sequence in the classical B-form for binding the EW dipeptide, while GCGC is the preferred dsDNA sequence in the curved nucleosomal form for the KE dipeptide. Cluster analysis revealed that potential target genes for the EW and KE peptides encode the AKT1 and AKT2 proteins involved in the development of the cytokine storm. The specific targets for the EW peptide are the ACE2 and CYSLTR1 genes, and specific target for the KE peptide is the CHUK gene. Protein products of the ACE2, CYSLTR1, and CHUK genes are functionally associated with IL-1ß, IL-6, TNF-α, IL-4, and IL-10 cytokines. An in vitro model of an inflammatory reaction demonstrated that Thymalin and EW and KE dipeptides reduced the synthesis of IL-1ß, IL-6, and TNF-α cytokines in human peripheral blood mononuclear cells by 1.4-6.0 times. The immunomodulatory effect of Thymalin under the inflammatory response conditions in COVID-19 is based on the potential ability of its active components, EW and KE dipeptides, to regulate protein synthesis involved in the development of the cytokine storm.

RESUMO

Aberrant mucus secretion is a hallmark of chronic obstructive pulmonary disease (COPD). Expression of the membrane-tethered mucins 3A and 3B (MUC3A, MUC3B) in human lung is largely unknown. In this observational cross-sectional study, we recruited subjects 45-65 years old from the general population of Stockholm, Sweden, during the years 2007-2011. Bronchial mucosal biopsies, bronchial brushings, and bronchoalveolar lavage fluid (BALF) were retrieved from COPD patients (n = 38), healthy never-smokers (n = 40), and smokers with normal lung function (n = 40). Protein expression of MUC3A and MUC3B in bronchial mucosal biopsies was assessed by immunohistochemical staining. In a subgroup of subjects (n = 28), MUC3A and MUC3B mRNAs were quantified in bronchial brushings using microarray. Non-parametric tests were used to perform correlation and group comparison analyses. A value of p < 0.05 was considered statistically significant. MUC3A and MUC3B immunohistochemical expression was localized to ciliated cells. MUC3B was also expressed in basal cells. MUC3A and MUC3B immunohistochemical expression was equal in all study groups but subjects with emphysema had higher MUC3A expression, compared to those without emphysema. Smokers had higher mRNA levels of MUC3A and MUC3B than non-smokers. MUC3A and MUC3B mRNA were higher in male subjects and correlated negatively with expiratory air flows. MUC3B mRNA correlated positively with total cell concentration and macrophage percentage, and negatively with CD4/CD8 T cell ratio in BALF. We concluded that MUC3A and MUC3B in large airways may be a marker of disease or may play a role in the pathophysiology of airway obstruction.
