Hip osteoarthritis (HOA) is a major contributor to functional impairment in older adults. Physical inactivity and comorbidities are commonly associated with declines in functional ability. However, the relationship between physical inactivity and functional outcomes in individuals with HOA, particularly those aged 80 years and older, remains underexplored. This study investigated the association between physical inactivity and functional limitations in older adults with HOA, focusing on two age groups: 60-79 years and 80-100 years. We analyzed data from Wave 5 of the Survey of Health, Aging, and Retirement in Europe (SHARE), constructing univariate and multivariable logistic regression models. Functional limitations served as dependent variables, with physical inactivity as the primary explanatory variable and number of chronic conditions, body mass index (BMI), gender, education, and depression as covariates. The study included 2,088 participants (mean age 73.1 ± 8.5 years; 73.7% female). Physical inactivity was reported by 16.8% (n =  261) of participants aged 60-79 years (n =  1,556; 72.5% female) and 49.6% of those aged 80-100 years (n =  532; 22.5% female). Poor handgrip strength and difficulty rising from a chair were significantly more prevalent among females aged 60-79 years (p <  0.002 for both). A marked decline in both physical activity and functional ability was observed between the two age groups. Physical inactivity emerged as an independent risk factor for reduced functioning across all outcomes, with stronger associations in the 80-100 years age group. Physical inactivity is a key predictor of functional decline in older adults with HOA, with its impact being particularly pronounced among those aged 80 years and older. These findings highlight the importance of physical activity to preserve functional abilities in this population.

Background The impact of anemia treatment with erythropoietin stimulating agents (ESA) on health-related quality of life (HRQOL) in chronic kidney disease (CKD) patients is controversial, particularly regarding optimal hemoglobin (Hb) target ranges. Methods We conducted a systematic review and meta-analysis of observational studies and randomized controlled trials (RCT) with ESA to estimate the effect of different achieved Hb values on physical HRQOL and functionality. We searched PubMed, EMBASE, CENTRAL, PEDro, PsycINFO and Web of Science databases, until May 2020. Two authors independently extracted data from studies. We included observational and RCTs that enrolled CKD patients undergoing anemia treatment with ESA with different achieved Hb levels among groups. We excluded studies with achieved Hb < 9 g/dL. For the meta-analysis, we included RCTs with control groups achieving Hb 10–11.5 g/dL and active groups with Hb > 11.5 g/dL. We analyzed the standardized mean difference (SMD) between groups for physical HRQOL. Results Among 8496 studies, fifteen RCTs and five observational studies were included for the systematic review. We performed the meta-analysis in a subset of eleven eligible RCTs. For physical role and physical function, SMDs were 0.0875 [95% CI: − 0.0025 – 0.178] and 0.08 [95% CI: − 0.03 – 0.19], respectively. For fatigue, SMD was 0.16 [95% CI: 0.09–0.24]. Subgroup analysis showed that trials with greater achieved Hb had greater pooled effects sizes — 0.21 [95% CI: 0.07–0.36] for Hb > 13 g/dL vs. 0.09 [95% CI: 0.02–0.16] for Hb 11.5–13 g/dL. Proportion of older and long-term diabetic patients across studies were associated with lower effect sizes. Conclusion Achieved hemoglobin higher than currently recommended targets may be associated with small but potentially clinically significant improvement in fatigue, but not in physical role or physical function. Younger and non-diabetic patients may experience more pronounced benefits of higher Hb levels after treatment with ESAs.

Objective To evaluate the extent to which circulating biomarker and supplements of vitamin D are associated with mortality from cardiovascular, cancer, or other conditions, under various circumstances.Design Systematic review and meta-analysis of observational studies and randomised controlled trials.Data sources Medline, Embase, Cochrane Library, and reference lists of relevant studies to August 2013; correspondance with investigators.Study selection Observational cohort studies and randomised controlled trials in adults, which reported associations between vitamin D (measured as circulating 25-hydroxyvitamin D concentration or vitamin D supplement given singly) and cause specific mortality outcomes.Data extraction Data were extracted by two independent investigators, and a consensus was reached with involvement of a third. Study specific relative risks from 73 cohort studies (849 412 participants) and 22 randomised controlled trials (vitamin D given alone versus placebo or no treatment; 30 716 participants) were meta-analysed using random effects models and were grouped by study and population characteristics.Results In the primary prevention observational studies, comparing bottom versus top thirds of baseline circulating 25-hydroxyvitamin D distribution, pooled relative risks were 1.35 (95% confidence interval 1.13 to 1.61) for death from cardiovascular disease, 1.14 (1.01 to 1.29) for death from cancer, 1.30 (1.07 to 1.59) for non-vascular, non-cancer death, and 1.35 (1.22 to 1.49) for all cause mortality. Subgroup analyses in the observational studies indicated that risk of mortality was significantly higher in studies with lower baseline use of vitamin D supplements. In randomised controlled trials, relative risks for all cause mortality were 0.89 (0.80 to 0.99) for vitamin D3 supplementation and 1.04 (0.97 to 1.11) for vitamin D2 supplementation. The effects observed for vitamin D3 supplementation remained unchanged when grouped by various characteristics. However, for vitamin D2 supplementation, increased risks of mortality were observed in studies with lower intervention doses and shorter average intervention periods.Conclusions Evidence from observational studies indicates inverse associations of circulating 25-hydroxyvitamin D with risks of death due to cardiovascular disease, cancer, and other causes. Supplementation with vitamin D3 significantly reduces overall mortality among older adults; however, before any widespread supplementation, further investigations will be required to establish the optimal dose and duration and whether vitamin D3 and D2 have different effects on mortality risk.

Cardiovascular disease (CVD) risk factors, incidence and death increases from around the time of menopause comparing to women in reproductive age. A healthy lifestyle can prevent CVD, but it is unclear which lifestyle factors may help maintain and improve cardiovascular health for women after menopausal transition. We conducted a systematic review and meta-analysis of prospective cohort studies to evaluate the association between modifiable lifestyle factors (specifically smoking, physical activity, alcohol intake, and obesity), with CVD and mortality in middle-aged and elderly women. Pubmed, Embase, among other databases and reference lists were searched until February 29th, 2016. Study specific relative risks (RR) were meta-analyzed using random effect models. We included 59 studies involving 5,358,902 women. Comparing current versus never smokers, pooled RR were 3.12 (95% CI 2.15-4.52) for CHD incidence, 2.09 (95% CI 1.51-2.89) for stroke incidence, 2.76 (95% CI 1.62-4.71) for CVD mortality and 2.22 (95% CI 1.92-2.57) for all-cause mortality. Physical activity was associated with a decreased risk of 0.74 (95% CI 0.67-0.80) for overall CVD, 0.71 (95% CI 0.67-0.75) for CHD, 0.77 (95% CI 0.70-0.85) for stroke, 0.70 (95% CI 0.58-0.84) for CVD mortality and 0.71 (95% CI 0.65-0.78) for all-cause mortality. Comparing moderate drinkers versus non-drinkers, the RR was 0.72 (95% CI 0.56-0.91) for CHD, 0.63 (95% CI 0.57-0.71) for CVD mortality and 0.80 (95% CI 0.76-0.84) for all-cause mortality. For women with BMI 30-35 kg/m2 the risk was 1.67 (95% CI 1.24-2.25) for CHD and 2.3 (95% CI 1.56-3.40) for CVD mortality, compared to normal weight. Each 5 kg/m² increase in BMI was associated with 24% (95% CI 16-33%) higher risk for allcause mortality. This meta-analysis suggests that physical activity and moderate alcohol intake were associated with a reduced risk for CVD and mortality. Smoking and higher BMI were associated with an increased risk of these endpoints. Adherence to a healthy lifestyle may substantially lower the burden of CVD and reduce the risk of mortality among middle-aged and elderly women. However, this review highlights important gaps, as lack of standardized methods in assessing lifestyle factors and lack of accurate information on menopause status, which should be addressed by future studies in order to understand the role of menopause on the association between lifestyle factors and cardiovascular events.

Background Nonalcoholic fatty liver disease (NAFLD) is a silent disease with increasing prevalence. High levels of serum uric acid (SUA) have been associated with cardiometabolic diseases, yet the possible association between SUA levels and NAFLD is not elucidated. This article aim is to evaluate the possible association between SUA and NAFLD in a Brazilian population. Methods This retrospective study evaluated patients submitted to two evaluations between 2015 and 2016 at a preventive medicine service. The diagnosis of NAFLD was performed through abdominal ultrasound, and its progression was defined as favorable or unfavorable according to the degrees of steatosis. Patients with hyperthyroidism, pregnancy, viral hepatitis, use of methotrexate or anabolic steroids, significant alcohol consumption were excluded. Possible confounding factors were evaluated through a multivariate model. Results A total of 279 patients were included in the final sample. In the first evaluation, 20.1% were women and the mean age was 46.9 (± 7.9) years, with a mean body mass index of 27.3 (± 4.0) kg/m 2 . About 26.9% of the individuals were diagnosed with NAFLD, and the mean of SUA levels was 5.7 (± 1.4) mg/dL; a favorable progression of NAFLD was observed in 79.2% of the patients, and the SUA levels at baseline were not significantly associated with the NAFLD progression ( p  = 0.43). Conclusions Despite NAFLD high prevalence, SUA levels were not significantly associated with NAFLD progression in one year in this sample.

Background It remains unclear into which level the systolic blood pressure (SBP) should be lowered in order to provide the best cardiovascular protection among older people. Hypertension guidelines recommendation on attaining SBP levels <150 mmHg in this population is currently based on experts’ opinion. To clarify this issue, we systematically reviewed and quantified available evidence on the impact of achieving different SBP levels <150 mmHg on various adverse outcomes in subjects aged ≥60 years old receiving antihypertensive drug treatment. Methods We searched 8 databases to identify randomized controlled trials (RCTs) and post-hoc analyses or subanalyses of RCTs reporting the effects of attaining different SBP levels <150 mmHg on the risk of stroke, acute myocardial infarction, heart failure, cardiovascular mortality and all-cause mortality in participants aged ≥60 years. We performed random-effects meta-analyses stratified by study design. Results Eleven studies (> 33,600 participants) were included. Compared with attaining SBP levels ≥140 mmHg, levels of 130 to <140 mmHg were not associated with lower risk of outcomes in the meta-analysis of RCTs, whereas there was an associated reduction of cardiovascular mortality (RR 0.72, 95% CI 0.59–0.88) and all-cause mortality (RR 0.86, 95% CI 0.75–0.99) in the meta-analysis of post-hoc analyses or subanalyses of RCTs. Limited and conflicting data were available for the SBP levels of <130 mmHg and 140 to <150 mmHg. Conclusions Among older people, there is suggestive evidence that achieving SBP levels of 130 to <140 mmHg is associated with lower risks of cardiovascular and all-cause mortality. Future trials are required to confirm these findings and to provide additional evidence regarding the <130 and 140 to <150 mmHg SBP levels.

Evaluate current recommendation for the use of noninvasive ventilation (Bi-level positive airway pressure- BiPAP modality) in hypoxemic acute respiratory failure, excluding chronic obstructive pulmonary disease. Electronic searches in MEDLINE, Web of Science, Clinical Trials, and The Cochrane Central Register of Controlled Clinical Trials. We searched for randomized controlled trials comparing BiPAP to a control group in patients with hypoxemic acute respiratory failure. Endotracheal intubation and death were the assessed outcomes. Of the 563 studies found, nine met the inclusion criteria for this systematic review. The pooled RR (95% CI) for intubation in patients with acute pulmonary edema (APE)/community acquired pneumonia (CAP) and in immunosuppressed patients (cancer and transplants) were 0.61 (0.39–0.84) and 0.77 (0.60–0.93), respectively. For Intensive Care Units (ICU) mortality, the RR (95% CI) in patients with APE/CAP was 0.51 (0.22–0.79). The heterogeneity was low in all comparisons. NIV showed a significant protective effect for intubation in immunosuppressed patients (cancer and transplants) and in patients with APE/CAP. However, the benefits of NIV for other etiologies are not clear and more trials are needed to prove these effects. •Noninvasive ventilation reduces the risk of intubation in subgroups of acute hypoxemic patients.•Immunosuppressed, acute pulmonary edema and pneumonia patients may benefit most from NIV.•Well designed randomized clinical trials are required to address the benefit in other populations.

Objective To quantify the trend of ischaemic heart disease (IHD) deaths in Brazil during the last decade (2000–2010) for various population characteristics and to forecast the upcoming mortality trends across regions in Brazil until the year 2015. Design Nationwide comparative observational study. Patients and methods The population studied encompassed all adult residents (≥20 years) living in five Brazilian regions between 2000 and 2010. Demographic, economic and mortality data were obtained from Brazilian National Mortality Data System and National Applied Economics Research Institute. Subnotified deaths were redistributed proportionally to IHD deaths. Age-standardised mortality rates (ASMRs) per 100 000 inhabitants, by sex and region, were calculated employing a standard Brazilian population and constructing multivariate regression models to quantify and to project temporal trends. Main outcome measures Absolute numbers of death due to IHD and region-specific death rates in Brazil by age and sex. Results During the study period, 627 786 men and 452 690 women died due to IHD in Brazil. ASMR trends across all regions for men and women converged, driven by a declining trend in the South and Southeast and an opposite incline in the North and Northeast (p<0.05). Future projections demonstrated potential widening of the observed North–South gap in coming years. Conclusions The IHD death trend in Brazil has changed from a decline to a stagnant state. However, a significant discrepancy in mortality trends exists between the northern and southern regions, which is likely to widen further. Reappraisal of the public health policies tailored to populations with diverse socioeconomic structures is urgently required.

With the advent of the COVID-19 pandemic, numerous questions have arisen regarding the screening, diagnosis, treatment, and prognosis of infected patients. Among these, screening infected patients through body temperature measurement has proven ineffective. However, doubts persist regarding the role of fever as a prognostic factor in the disease. To assess the prevalence of fever and its relevance as a marker of mortality in COVID-19. This prospective and longitudinal cohort study was conducted between April 2020 and December 2021 and analyzed 1400 COVID-19 patients systematically admitted to the emergency department of a reference hospital during the period from April 2020 to December 2021, in the city of Curitiba, Brazil. [LG1] The study evaluated [LG2] the presence of fever (body temperature above 37,7ºC) upon admission and/or during hospitalization, patient profiles, and outcomes (in-hospital death, discharge, admission at the intensive care unit, need of mechanical ventilation). Fever was present in 128 participants (9.1%), with a higher prevalence in males (71%) and obese individuals (42.9%). Among the febrile patients, 39 required intubation (30.4%), with two intubated upon admission (1.5%), 104 were discharged (81.2%), and 24 deceased (18.7%). Fever was not associated with a higher mortality rate. Fever showed low prevalence, is more common in males and obese individuals, and is not related to worse clinical outcomes.
