UNASSIGNED: The association of cognitive function, its changes, and all-cause mortality has not reached a consensus, and the independence of the association between changes in cognitive function and mortality remains unclear. The purpose of this study was to evaluate the longitudinal association between baseline cognitive function and cognitive changes over 1 year with subsequent all-cause mortality among the older adults aged 60 and above.
UNASSIGNED: A prospective cohort study utilizing the Community Older Adults Health Survey data. Initiated in 2018, the study annually assessed all individuals aged 60+ in Dalang Town, Dongguan City. Cognitive function was assessed using the Chinese version of the Mini-Mental State Examination (MMSE). A total of 6,042 older adults individuals were included, and multivariate Cox proportional hazard models were used to examine cognitive function\'s impact on mortality.
UNASSIGNED: Participants\' median age was 70 years, with 39% men. Over a median 3.08-year follow-up, 525 died. Mortality risk increased by 6% per MMSE score decrease (adjusted HR = 1.06, 95%CI: 1.05-1.08). Compared to those with normal cognitive function at baseline, participants with mild cognitive impairment and moderate to severe cognitive impairment had significantly higher mortality risks (adjusted HR = 1.40, 95%CI: 1.07-1.82; HR = 2.49, 95%CI: 1.91-3.24, respectively). The risk of death was 5% higher for each one-point per year decrease in cognitive function change rate (HR = 1.05, 95%CI: 1.02-1.08). Compared with participants with stable cognitive function, those with rapid cognitive decline had a 79% increased risk of death (adjusted HR = 1.79, 95% CI: 1.11-2.87), with baseline cognitive function influencing this relationship significantly (P for interaction = 0.002).
UNASSIGNED: Baseline cognitive impairment and rapid cognitive decline are associated with higher all-cause mortality risks in Chinese older adults. Baseline function influences the mortality impact of cognitive changes.

Hypertriglyceridemia (HTG) is a common dyslipidemia associated with an increased risk of cardiovascular disease and pancreatitis. It is well stablished that the severe cases of disease often present with an underlying genetic cause. In this study, we determined the frequency and variation spectrum of genes involved in the triglyceride metabolism in a series of Brazilian patients with severe HTG. A total of 212 patients with very high HTG, defined with fasting triglycerides (TG) ≥ 880 mg/ dL, that underwent a multi-gene panel testing were included in this research. Germline deleterious variants (i.e. Pathogenic/Likely Pathogenic (P/LP) variants) were identified in 28 out of 212 patients, reflecting an overall diagnostic yield of 13% in our cohort. Variants of unknown significance (VUS) were identified in 87 patients, and represent 80% of detected variants in this dataset. We confirm the LPL as the most frequently mutated gene in patients with severe HTG, and we had only one suspected case of familial chylomicronemia syndrome, caused by a homozygous variant in LMF1, in our cohort. Notably, we report 16 distinct and novel variants (P/LP and VUS), each of them representing a single case, not previously reported in any public databases or other studies. Our data expand our knowledge of genetic variation spectrum in patients with severe HTG in the Brazilian population, often underrepresented in public genomic databases, being also a valuable clinical resource for genetic counseling and healthcare programs in the country.

UNASSIGNED: To examine the potential association between polycystic ovary syndrome (PCOS) and hyperuricemia and to elucidate the underlying contributory factors.
UNASSIGNED: Retrospective study on 603 women with PCOS and 604 women without PCOS. Anthropometric features, reproductive hormone profiles, and metabolic parameters were measured and compared between two groups of patients. Examinations of correlations between SUA levels and other parameters were conducted to discern potential correlations.
UNASSIGNED: Both serum uric acid levels and the incidence of hyperuricemia exhibited statistically significant elevations in women with PCOS when compared to their counterparts without PCOS. Nonetheless, this statistical difference was not found between the obese subgroup after stratifying study subjects by body mass index (BMI). Pearson\'s correlation analysis underscored the prominence of BMI as a robust factor influencing SUA levels in women, regardless of their PCOS status. Furthermore, multivariable linear regression model demonstrated significant positive associations between SUA levels and several variables, namely dehydroepiandrosterone sulfate (DHEA-S), free androgen index (FAI), total cholesterol (TC), triglycerides (TG), free fatty acids (FFA), fasting insulin (FINS), homeostatic model assessment of insulin resistance (HOMA-IR), area under the curve for insulin (AUC-I), alanine aminotransferase (ALT), and aspartate aminotransferase (AST). Additionally, it is noteworthy that the prevalence of hyperuricemia exhibited a positive association with fasting plasma glucose (FPG) levels, while conversely, it displayed a negative association with estradiol (E2) levels.
UNASSIGNED: PCOS is associated with a significant elevation of SUA level and hyperuricemia prevalence. HA, IR, and dyslipidemia may be the mediators in the pathogenesis of hyperuricemia in women with PCOS.

UNASSIGNED: Despite the fact that China amounts to one-fifth of the world\'s population, has a higher proportion of the elderly, and has a higher prevalence of osteoporosis and fracture, limited studies have investigated the association between dietary patterns and bone mineral density (BMD) as well as fracture risk among the elderly Chinese population. We aimed to investigate the association between different dietary patterns and BMD as well as the risk of fractures, and this association may vary between elderly women and men.
UNASSIGNED: Building upon the China Osteoporosis Prevalence Study, we included 17,489 subjects aged ≥40 years old randomly sampled across 44 counties/districts of 11 provinces or municipalities in China who completed a food frequency questionnaire. BMD was measured by dual x-ray absorptiometry. Vertebral fracture was defined based on lateral spine radiographs using the semi-quantitative technique of Genant.
UNASSIGNED: A diet rich in \"carnivorous\", \"vegetarian\", \"dairy, fruit, and egg\" was significantly associated with higher BMD at total hip (TH), femoral neck (FN), and lumbar spine 1-4 (L1-4). Yet, a diet rich in \"beverage and fried food\" was associated with a lower BMD at the FN and L1-4. High quartiles of the carnivorous diet were associated with 34%-39% reduced risk of clinical fracture in the past 5 years and vertebral fracture. Stronger associations were observed among women. Sensitivity analysis among postmenopausal women presented even stronger positive associations between carnivorous and vegetarian diets and high BMD, as well as between carnivorous diet and reduced risk of fractures.
UNASSIGNED: Our study suggested that a diet rich in meat, vegetables, and dairy, fruit, and eggs might be associated with greater BMD and a lower fracture risk, while beverage and fried foods may be associated with a lower BMD at L1-4, especially among elderly women. These findings are relevant to provide recommendations on dietary nutrition regarding the elderly population at high risk of osteoporosis and fractures, especially postmenopausal women.

Teriparatide, an osteoanabolic agent, is a biosynthetic analogue of the 1-34 amino acids of human parathyroid hormone (PTH) used for the treatment of osteoporosis. It is typically well-tolerated; common side effects include headaches, arthralgias, nausea, and dizziness. In this report, we present a case of gynecomastia occurring shortly after initiating teriparatide therapy, associated with nipple sensitivity and breast tenderness. Secondary workup for various causes of gynecomastia was unremarkable. Finally, a decision was made to discontinue teriparatide due to the patient\'s concerns. The nipple sensitivity started improving shortly afterward, with complete resolution of gynecomastia 4 months later. Although this unusual side effect has been reported as a possibility in postmarketing studies, a chronological report on the occurrence of teriparatide-induced gynecomastia and its complete resolution after discontinuing teriparatide has not yet been published in the literature.

UNASSIGNED: This study aims to investigate the effect of age on disease activity and biological treatment in patients with ankylosing spondylitis (AS).
UNASSIGNED: A total of 811 AS patients registered in the TURKBIO registry database between 2011 and 2019 were categorized according to their age at the time of entry into the registry and assigned to one of two groups: young patients, defined as <60 years of age (n=610), and those aged ≥60 years (n=201) were recorded as elderly patients. Demographic, clinical, and laboratory characteristics, along with disease activity markers and other follow-up parameters, as well as current and prior treatments, were electronically recorded during each visit using open-source software.
UNASSIGNED: The mean age of the elderly patients was 67±5.8 years, while the mean age of the younger patients was 49.2±10.9 years. Male predominance was lower in the older AS group compared to the younger AS group (p=0.002). During follow-up period, 397 patients (comprising 318 young and 79 elderly individuals) had a history of using at least one biological disease-modifying agent (bDMARD). There was no significant difference between the groups in terms of DMARD and bDMARD-use distributions. First tumor necrosis factor inhibitor (TNFi) retention rates were found to be similar in both groups over 10 years of follow-up. Adverse events were found to be similar in young (19.9%) and elderly (26.8%) AS patients.
UNASSIGNED: Research in the TURKBIO cohort reveals that both older and younger patients with AS exhibited similar disease activity levels with comparable treatment approaches. Moreover, the results of TNFi treatments in elderly patients were the same as those observed in younger patients, with no notable increase in safety concerns.

UNASSIGNED: Antimony (Sb) has been identified as a new neurotoxicant that impacts neurological functions in animal studies. However, its effects on the human population remain unknown.
UNASSIGNED: The study reveals that there is an association between exposure to Sb and a higher incidence of cognitive impairment in older adults. The dose-response curve demonstrates that the risk of cognitive impairment consistently increased with higher levels of Sb exposure without a discernible threshold.
UNASSIGNED: Reducing exposure to Sb may have a beneficial effect in delaying or preventing the onset of cognitive impairment. This intervention has the potential to significantly decrease the disease burden associated with cognitive impairment, ultimately contributing to social development.

UNASSIGNED: The decision to undertake a surgical intervention for an emergency general surgery (EGS) condition (appendicitis, diverticulitis, cholecystitis, hernia, peptic ulcer, bowel obstruction, ischemic bowel) involves a complex consideration of factors, particularly in older adults. We hypothesized that identifying variability in the application of operative management could highlight a potential pathway to improve patient survival and outcomes.
UNASSIGNED: We included adults aged 65+ years with an EGS condition from the 2016-2017 National Inpatient Sample. Operative management was determined from procedure codes. Each patient was assigned a propensity score (PS) for the likelihood of undergoing an operation, modeled from patient and hospital factors: EGS diagnosis, age, gender, race, presence of shock, comorbidities, and hospital EGS volumes. Low and high probability for surgery was defined using a PS cut-off of 0.5. We identified two model-concordant groups (no surgery-low probability, surgery-high probability) and two model-discordant groups (no surgery-high probability, surgery-low probability). Logistic regression estimated the adjusted OR (AOR) of in-hospital mortality for each group.
UNASSIGNED: Of 375 546 admissions, 21.2% underwent surgery. Model-discordant care occurred in 14.6%; 5.9% had no surgery despite a high PS and 8.7% received surgery with low PS. In the adjusted regression, model-discordant care was associated with significantly increased mortality: no surgery-high probability AOR 2.06 (1.86 to 2.27), surgery-low probability AOR 1.57 (1.49 to 1.65). Model-concordant care showed a protective effect against mortality (AOR 0.83, 0.74 to 0.92).
UNASSIGNED: Nearly one in seven EGS patients received model-discordant care, which was associated with higher mortality. Our study suggests that streamlined treatment protocols can be applied in EGS patients as a means to save lives.
UNASSIGNED: III.

BACKGROUND: We conducted analyses of the association between smoking and osteoporosis and osteoporotic fractures using a secondary dataset analysis of the National Health and Nutrition Examination Survey (NHANES) database and the two-sample Mendelian randomization (MR) method.
METHODS: The associations between smoking and osteoporosis or osteoporotic fractures were analyzed using weighted logistic regression models for both univariate and multivariable analyses using pooled 1999-2018 NHANES data. The summary-level data of genome-wide association studies (GWAS) of smoking and osteoporosis were extracted from the IEU Open GWAS project. The inverse variance weighted method was used as the main method for the two-sample MR analysis.
RESULTS: We obtained the following main findings based on the NHANES data: smoking was associated with osteoporosis according to the analyses of 30856 participants (OR=1.21; 95% CI: 1.06-1.39, p=0.004); smoking was associated with hip osteoporotic fracture according to the analyses of 30928 participants (OR=1.47; 95% CI: 1.14-1.90, p=0.004); smoking was associated with wrist osteoporotic fracture according to the analyses of 30923 participants (OR=1.33; 95% CI: 1.18-1.49, p<0.001); and smoking was associated with spine osteoporotic fracture according to the analyses of 30910 participants (OR=1.43, 95% CI: 1.18-1.73, p<0.001). In addition, we confirmed the potential causal effect of smoking on the risk of osteoporotic fracture (OR=24.5; 95% CI: 1.11-539, p=0.043) by conducting two-sample MR analyses.
CONCLUSIONS: Smoking was associated with increased risks of both osteoporosis and osteoporotic fracture. Smoking showed a potential causal effect on the risk of osteoporotic fracture.

The world\'s population is experiencing an aging process, which is resulting in an increase in diseases such as Alzheimer\'s disease. Consequently, more and more people need care, which can lead to overload and harm to their family\'s quality of life.
UNASSIGNED: Identify the psychosocial factors affected by the burden on family caregivers of people with Alzheimer\'s disease.
UNASSIGNED: Forty-nine family caregivers of people with Alzheimer\'s disease, from a city in Minas Gerais, Brazil, participated in the study. They filled out a form of sociodemographic variables, and answered the Burden Interview Scale (BI-Zarit), Quality of Life in Alzheimer\'s Disease Caregiver version (CQoL-AD), the Depression, Anxiety and Stress Scale (DASS-21), the Mindfulness and Awareness Scale (MAAS) and the Clinical Dementia Rating Scale (CDR).
UNASSIGNED: All participants were female with an average age of 54.26 (±8.99). Daughters comprised 77.55% of the sample, and 34.69% were sole caregivers. The Bi-Zarit scale positively and significantly correlated with DASS-21 Depression (r=0.440; p=0.002), DASS-21 Anxiety (r=0.415; p=0.003), DAAS-21 Stress (r=0.583; p<0.001). On the other hand, it showed a negative correlation with MAAS (r=-0.429; p=0.002) and CQoL-AD (r=-0.533; p<0.001).
UNASSIGNED: This study demonstrates that family caregivers of people with Alzheimer\'s disease may be overloaded, and that the heavier the burden, the lower level of attention, the worse quality of life and the greater the possibility for the caretaker to present symptoms of depression, anxiety, and stress.
A população mundial vive um processo de envelhecimento que está resultando no aumento de doenças, como a doença de Alzheimer. Consequentemente, cada vez mais pessoas necessitam de cuidados, o que pode gerar sobrecarga e prejuízos à qualidade de vida de seus familiares.
UNASSIGNED: Identificar os fatores psicossociais afetados pela sobrecarga em cuidadores familiares de pessoas com doença de Alzheimer.
UNASSIGNED: Participaram do estudo 49 cuidadores familiares de pessoas com doença de Alzheimer, de um município de Minas Gerais, Brasil. Os participantes preencheram um formulário de variáveis sociodemográficas e responderam à escala de Sobrecarga (BI-Zarit), à escala de Qualidade de Vida na Doença de Alzheimer versão Cuidador (CQdV-DA), à escala de Depressão, Ansiedade e Estresse (DASS-21), à escala de Atenção Plena e Consciência (MAAS) e à escala de Avaliação Clínica de Demência (CDR).
UNASSIGNED: Todos os participantes eram do sexo feminino, com idade média de 54,26 (±8,99). As filhas representaram 77,55% da amostra e 34,69% eram cuidadoras exclusivas. A escala Bi-Zarit correlacionou-se positiva e significativamente com a DASS-21 Depressão (r=0,440; p=0,002), DASS-21 Ansiedade (r=0,415; p=0,003), DAAS-21 Estresse (r=0,583; p<0,001). Por outro lado, mostrou correlação negativa com MAAS (r=-0,429; p=0,002) e CQoL-AD (r=-0,533; p<0,001).
UNASSIGNED: Este estudo demonstra que os cuidadores familiares de pessoas com doença de Alzheimer podem estar sobrecarregados e que, quanto maior a sobrecarga, menor o nível de atenção, pior a qualidade de vida e maior a possibilidade de apresentar sintomas de depressão, ansiedade, estresse.
