Analysis of sarcopenic obesity prevalence and diagnostic agreement according to the 2022 ESPEN and EASO Consensus in hospitalized older adults with severe obesity.

Background: Sarcopenic obesity (SO) is a clinical disorder characterized by increased adiposity and decreased muscle mass and function, commonly observed in older adults. However, most of the studies that investigated SO prevalence rates were not based on current standardized diagnostic methods. Thus, this study aims to estimate the prevalence rates of SO and their level of agreement using different instruments proposed by the European Society for Clinical Nutrition and Metabolism (ESPEN) and the European Association for the Study of Obesity (EASO) Consensus, in a sample of hospitalized older adults with severe obesity. Methods: A cross-sectional study with 90 older adults (≥ 60 years) with severe obesity (body mass index ≥ 35 kg/m/²) seeking an in-hospital multidisciplinary body weight reduction program. Skeletal muscle function was assessed using the five-repetition Sit-Stand test (5-SSt) and Handgrip Strength (HGS). Body composition was evaluated by high percentages of fat mass (FM), low appendicular lean mass (ALM/W), and skeletal muscle mass (SMM/W), adjusted to body weight. The stage of SO was assessed on the presence of at least one comorbidity and specific cut-offs were adopted for each step. All analyses were performed according to gender and age range. Results: The prevalence rates of SO in the total sample were 23.3%, 25.5%, 31.1%, and 40.0% considering altered values of 5-SSt+FM+ALM/W, HGS+FM+ALM/W, 5-SSt+FMSSM/W, and HGS+FM+SSM/W, respectively. Higher prevalence rates were observed among female and old elderly subgroups, regardless of the diagnostic combination. There were weak agreements between the muscle function tests (5-SSt versus HGS) using both muscle mass indexes in the total sample and all subgroups. Moderate agreements were observed between muscle mass indexes (SMM/W versus ALM/W) in the total sample, male and younger older adults (using 5-SSt), and strong agreements for men and younger older adults (using HGS). Conclusion: The discrepancies observed between the prevalence rates and their levels of agreement reinforce the need for new studies in similar populations aiming for better standardization of SO assessment.

Factors associated with clinical severity in chronic venous disease: The role of functional parameters.

INTRODUCTION: Chronic venous disease (CVD) is a highly prevalent disease that presents a wide spectrum of clinical expressions due to abnormalities in the venous system. Patients often have major functional changes that can limit daily activities. However, the functional factors associated with the severity of the disease remain poorly understood. OBJECTIVE: To identify the functional factors associated with CVD severity. METHODS: Seventy-five patients with CVD (92.0% females, 49.6 ± 13.3 years) were evaluated through clinical examination, lower limb perimetry, ankle range of motion (AROM), and lower limb muscle strength by the Heel Rise test, and Sit-to-stand test. Patients were stratified according to the disease severity as mild (telangiectasia, varicose veins, or edema in the lower limbs) or severe CVD (trophic changes or venous ulcer). RESULTS: Patients with severe CVD (n = 13) were older (p = 0.002), predominantly male (p = 0.007), with reduced AROM in dorsiflexion (p = 0.028) and inversion (p = 0.009), reduced lower limb strength by the Heel Rise test (p = 0.040), and greater circumference of the calf (p = 0.020), ankle (p = 0.003), and plantar arch (p = 0.041) when compared to mild CVD (n = 62). Advanced age, male sex, lower ankle range of motion in dorsiflexion, and greater ankle and plantar arch circumferences were associated with CVD severity. However, the ankle circumference (OR 1.258, 95% CI: 1.008-1.570; p = 0.042), together with advanced age and male sex, was the only functional variable that remained independently associated with CVD severity. CONCLUSION: The increased ankle circumference was a determinant of the CVD severity and may assist in risk stratification and guide treatment goals in this population.

International consensus on sleep problems in pediatric palliative care: Paving the way.

OBJECTIVE: Sleep problems constitute a common and heterogeneous complaint in pediatric palliative care (PPC), where they often contribute to disease morbidity and cause additional distress to children and adolescents and their families already facing the burden of life-threatening and life-limiting conditions. Despite the significant impact of sleep problems, clinical evidence is lacking. The application of general pediatric sleep recommendations appears insufficient to address the unique challenges of the PPC dimension in terms of disease variability, duration, comorbidities, complexity of needs, and particular features of sleep problems related to hospice care. Therefore, we initiated an international project aimed at establishing a multidisciplinary consensus. METHODS: A two-round Delphi approach was adopted to develop recommendations in the areas of Definition, Assessment/Monitoring, and Treatment. After selecting a panel of 72 worldwide experts, consensus (defined as ≥75% agreement) was reached through an online survey. RESULTS: At the end of the two voting sessions, we obtained 53 consensus recommendations based on expert opinion on sleep problems in PPC. CONCLUSIONS: This study addresses the need to personalize sleep medicine's approach to the palliative care setting and its peculiarities. It provides the first international consensus on sleep problems in PPC and highlight the urgent need for global guidance to improve sleep-related distress in this vulnerable population and their caregivers. Our findings represent a crucial milestone that will hopefully enable the development of guidelines in the near future.

The Influence of Physical Exercises on the Flexibility of Older Individuals with Knee Osteoarthritis: A Systematic Review.

Background: Flexibility is a component of functional capacity and is relevant in maintaining the musculature and structures adjacent to the joints. Then, the improvement of the flexibility must be a critical goal in the rehabilitation programs. By improving flexibility in knee osteoarthritis (KOA) individuals, the pain is relieved, the risk of injury is reduced, and the need for surgical interventions is delayed. We aimed to summarize the available literature on the influence of different physical exercise modalities on flexibility in older KOA individuals. Methods: This study followed the PRISMA statement and registered in PROSPERO (CRD42020195786). Seven databases (MEDLINE/PubMed; PEDro; CINAHL; Scopus; Web of Science; Embase; and SPORTDiscus) were screened for papers published prior to Sep 6, 2022. The PEDro scale, Cochrane collaborations, and ROBINS-I tools were used to evaluate the methodological quality and risk of bias. Results: Ten studies (including 438 participants diagnosed with KOA) fulfilled the eligibility criteria, and nine concluded that flexibility was improved after a physical exercise program. Conclusion: Despite the modality, physical exercise improves flexibility in older KOA individuals, improving the functional capacity. Health professionals engaged in KOA rehabilitation should use physical exercise as a strategy to improve the flexibility of this population.

RELATIONSHIP BETWEEN RESIDUAL DIURESIS AND SARCOPENIA IN PATIENTS ON HEMODIALYSIS.

OBJECTIVE: To assess the association of residual diuresis with sarcopenia in patients with Chronic Kidney Disease (CKD) on hemodialysis. METHODS: Through a cross-sectional study, patients on hemodialysis were subjected to a Dual Energy Radiologic Absorption (DEXA) exam to record muscle mass. Based on the volume of urine collected in 24 hours, patients were classified as anuric (diuresis ≤ 100 mL/day) or non-anuric (diuresis > 100 mL/day). Functional performance was evaluated by Short Physical Performance Battery (SPPB) and muscle strength by handgrip strength and 5-repetition sit-to-stand test. The association between the absence of residual urine and the presence of sarcopenia, low SPPB, and low muscle strength was analyzed using a binary logistic regression model. RESULTS: Ninety-two patients, with a mean age of 54.4 years (95% CI 51.3 - 57.4) and with a mean diuresis volume of 476.3 mL/day (95% CI 320.4 - 632.2) were evaluated (48 anuric and 44 non-anuric). Anuric patients had a 2.77 (95% CI 1.14 - 6.73) times greater probability of sarcopenia and had a 3.55 (1.14 - 11.0) times greater probability of low SPPB, regardless of gender, age, and time on dialysis. Gender was the other associated variable for the presence of sarcopenia, with males having a 3.30 (95% CI 1.34 - 8.13) times higher risk. There were no associations with muscle strength. CONCLUSION: The absence of residual diuresis in patients on hemodialysis is associated with a higher risk of sarcopenia and low functional performance.

Impact of upadacitinib induction and maintenance therapy on health-related quality of life, fatigue, and work productivity in patients with moderately-to-severely active Crohn's disease.

BACKGROUND AND AIMS: Quality of life in patients with active Crohn's disease may be significantly reduced. We evaluated the effects of upadacitinib induction and maintenance therapy on fatigue, quality of life, and work productivity in the phase 3 trials U-EXCEL, U-EXCEED, and U-ENDURE. METHODS: Clinical responders to upadacitinib 45 mg in U-EXCEL and U-EXCEED induction trials were re-randomized 1:1:1 to upadacitinib 30 mg, 15 mg, or placebo for 52 weeks of maintenance in U-ENDURE. Clinically meaningful improvements in Inflammatory Bowel Disease Questionnaire (IBDQ) response, IBDQ remission, Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue), and Work Productivity and Activity Impairment were evaluated. Percentages of patients achieving clinically meaningful improvements were assessed at induction Weeks 4 and 12 and maintenance Week 52. RESULTS: Analysis included 1021 and 502 patients assessed at induction and maintenance, respectively. In U-EXCEL, greater improvements (all p≤0.001) in IBDQ response (71.0% vs 50.2%), IBDQ remission (44.2% vs 23.7%), and FACIT-Fatigue (42.0% vs 27.0%) were observed in upadacitinib-treated patients versus placebo at Week 4. Improvements in IBDQ response, IBDQ remission, and FACIT-Fatigue were similar or greater at Week 12. Clinically meaningful improvement in overall work impairment (52.1% vs 38.1%, p≤0.05) was demonstrated at Week 12. Similar results were observed in U-EXCEED. Improvements were sustained through 52 weeks of upadacitinib maintenance treatment. CONCLUSIONS: In patients with active Crohn's disease, upadacitinib treatment relative to placebo significantly improved fatigue, quality of life, and work productivity as early as Week 4. These effects were sustained through 52 weeks of maintenance.

The usefulness of patient-reported outcome measures in decision making in Chagas cardiomyopathy: a scoping review.

Chagas cardiomyopathy (ChC) presents many biopsychosocial complexities, highlighting the need to have patient self-report questions. This study demonstrates the scope of the use of patient-reported outcome measures (PROMs) in patients with ChC and highlights the main research gaps. This is a scoping review and the search strategy was performed in the Online Medical Literature Analysis and Retrieval System (MEDLINE), Excerpta Medica database (EMBASE), Accumulated Index of Nursing and Allied Health Literature (CINAHL), Cochrane Central, Latin American Literature and Caribbean in Health Sciences (LILACS) and Diagnostic Test Accuracy (DITA). The search identified 4484 studies and 20 studies met the inclusion criteria. The Short-Form of 36 items (SF-36) had potential prognostic value and the ability to identify systolic dysfunction. The Human Activity Profile was able to screen for functional impairment, and the New York Heart Association showed potential prognostic value. The SF-36 and Minnesota Living with Heart Failure Questionnaire were responsive to interventions. The pharmaceutical care affected adherence to treatment as assessed by the Morisky score and also for SF-36. Despite the increased use of PROMs, there are still a large number of gaps in the literature, and further studies using PROMs are needed.

Factors associated with adherence to the COVID-19 vaccine in pregnant women.

OBJECTIVE: to identify factors associated with adherence to the COVID-19 vaccine during pregnancy. METHOD: cross-sectional and analytical study with 348 postpartum women in shared accommodation at the Municipal Maternities of Recife-PE. Data was collected through interviews during the months of June to September 2022. Pearson's Chi-Square or Fisher's Exact tests and the Poisson regression model were applied for statistical analysis. RESULTS: 17.2% of pregnant women adhered to the complete vaccination schedule, and adherence was associated with access to the internet/TV/radio (p-value = 0.011), routine prenatal vaccination (p-value = 0.019), safety of the efficacy of the COVID-19 vaccine and partner support (p-value = 0.020). Postpartum women without access to the internet/TV/radio, and who feel confident about the effectiveness of the vaccine, had higher prevalence rates for adhering to COVID-19 vaccination, with PRs of 2.56 and 3.25, respectively. CONCLUSION: there was evidence of low adherence to the vaccination schedule against COVID-19 during the gestational period, considering the number of recommended doses and the interval between them. Therefore, professionals in their clinical practice must make pregnant women aware of the importance of immunization and compliance with the vaccination schedule. BACKGROUND: (1) Maternal vaccination plays a significant role in preventing and combating maternal morbidity. (2) Some factors may influence acceptance or hesitancy of the COVID-19 vaccine during pregnancy. (3) Safety regarding the effectiveness of vaccination against COVID-19 during pregnancy is a factor associated with adherence to COVID-19 vaccines. (4) Postpartum women without access to the internet/TV/radio have 2.56 times the risk of adhering to the COVID-19 vaccination schedule. (5) Health education helps to increase the level of knowledge and acceptance of the vaccine by pregnant women.

How Do Healthcare Professionals Develop the Communication Process to Promote Patients' Health Literacy?

This study aimed to analyze the communication process of healthcare professionals for the promotion of health literacy. It is a qualitative study that utilized individual online interviews with 46 healthcare professionals working in Brazil. The thematic content analysis technique proposed by Bardin was employed, and Atlas Ti software assisted in the assessment and interpretation of the texts. Content categorization revealed 26 sub-themes, and the coding of these identified nine themes and three categories. The communication process in health literacy education was composed of a set of interdependent and interrelated variables termed emotions, professional preparedness, interprofessional collaboration, patient needs assessment, building rapport, family inclusion in the educational process, environmental aspects, strategies, and resources for teaching and learning. These data may support the analysis of health communication in healthcare services, the creation of data collection instruments, and the development of training programs to enhance skills within the context of the identified variables.

Cognitive function is associated with performance in time up and go test and with leptin blood levels in community-dwelling older women.

Considering the challenge that cognitive dysfunction and dementia represent to health is imperative to prioritize early diagnosis strategies and explore the pathophysiological mechanisms. There is no consensus on specific markers and physical tests that indicate cognitive decline in older. The objective of this study was to evaluate a panel of inflammatory biomarkers and physical function and investigate their association with cognitive function in community-dwelling older women. Seventy-one participants were included in this study. Cognitive function was assessed by Mini Mental State Examination, muscle strength using dynamometer, body composition using Dual X-ray absorptiometry, respiratory muscle strength using manuvacuometer, and physical function using the Short Physical Performance Battery and Time Up and Go (TUG) tests. Blood samples were collected to analyze a panel of inflammatory biomarkers. The cognitive function was associated with TUG (ß = - 0.48; 95%IC = - 0.54 to - 0.21; p < 0.001), inspiratory muscle strength (ß = 0.30; 95%IC = 0.005-0.03; p = 0.009), and leptin concentrations (ß = 0.32; 95% IC = 0.001-0.006; 0.007). Time spent on TUG test and leptin levels accounted for 27% of variability in cognitive function independent of age. Poorer physical function with leptin plasma levels is associated with decreased cognitive function in older women. These findings contribute to comprehension of pathophysiology underlying cognitive decline and informing the development of new approaches to prevent, diagnose, monitoring and treat cognitive decline in aging.

Upadacitinib Reduces Crohn's Disease Symptoms Within the First Week of Induction Therapy.

BACKGROUND & AIMS: Upadacitinib (UPA), an oral Janus kinase inhibitor, is approved to treat moderately to severely active Crohn's disease (CD). Because symptomatic response is an important initial treatment goal for patients, we evaluated the rapidity of symptomatic improvement in patients with CD receiving UPA 45 mg once daily (UPA45) induction therapy. METHODS: This post hoc analysis included pooled data from 2 phase 3, multicenter, double-blind, 12-week induction trials (U-EXCEL and U-EXCEED) and 1 maintenance trial (U-ENDURE). Daily diary data for the first 15 days of UPA45 or placebo (PBO) treatment were used to analyze improvement in very soft/liquid stool frequency (SF) and abdominal pain score (APS). Clinical outcomes were evaluated at every study visit. RESULTS: Overall, 1021 patients (n = 674 UPA45; n = 347 PBO) were analyzed. UPA45 demonstrated greater efficacy vs PBO for SF <3 and APS ≤1, providing rapid relief by day 5 or 6, regardless of prior biologic exposure. Mean changes in SF and APS were greater with UPA45 beginning at week 2 (-2.0 and -0.5, respectively; P < .001) and were maintained through week 12 (-3.0 and -1.0, respectively; P < .001) vs PBO. The first achievement of daily SF/APS clinical remission occurred earlier with UPA45 (median, 13 d) vs PBO (median, 32 d), and patients treated with UPA45 showed improved rates of SF/APS clinical remission (21.1% UPA45 vs 8.9% PBO) and clinical response (58.8% UPA45 vs 37.9% PBO) starting at week 2 (both P ≤ .01). CONCLUSIONS: UPA45 provided rapid relief of clinical symptoms within the first week of treatment in patients with CD. CLINICALTRIALS: gov numbers: NCT03345849, NCT03345836, and NCT03345823.

Bioaccumulation of trace metals in the plastisphere: Awareness of environmental risk from a European perspective.

The term "Plastisphere" refers to the biofilm layer naturally formed by microorganisms attaching to plastic surfaces. This layer possesses the capability to adsorb persistent organic and inorganic pollutants, particularly trace metals, which are the focus of this research study. Immersion experiments were concurrently conducted in five locations spanning four European countries (France, Ireland, Spain, and Italy) utilising eight distinct polymers. These immersions, repeated every three months over a one-year period, aimed to evaluate the baseline bioaccumulation of 12 trace metals. The study underscores the intricate nature of metal bioaccumulation, influenced by both micro-scale factors (such as polymer composition) and macro-scale factors (including geographical site and seasonal variations). Villefranche Bay in France exhibited the lowest metals bioaccumulation, whereas Naples in Italy emerged as the site where bioaccumulation was often the highest for the considered metals. Environmental risk assessment was also conducted in the study. The lightweight nature of certain plastics allows them to be transported across significant distances in the ocean. Consequently, evaluating trace metal concentrations in the plastisphere is imperative for assessing potential environmental repercussions that plastics, along with their associated biota, may exert even in locations distant from their point of emission.

Upadacitinib Achieves Clinical and Endoscopic Outcomes in Crohn's Disease Regardless of Prior Biologic Exposure.

BACKGROUND & AIMS: Upadacitinib, an oral Janus kinase inhibitor, achieved significantly higher rates of clinical remission and endoscopic response vs placebo during induction (U-EXCEL [NCT03345849], U-EXCEED [NCT03345836]) and maintenance (U-ENDURE [NCT03345823]) treatment in patients with moderate-to-severe Crohn's disease. Prior biologic failure is often associated with reduced responses to subsequent therapies. This post hoc analysis assessed upadacitinib efficacy by prior biologic failure status. METHODS: Patients were randomized to placebo or upadacitinib 45 mg (UPA45) for 12 weeks (induction). UPA45 clinical responders were enrolled in U-ENDURE and rerandomized to placebo, upadacitinib 15 mg, or upadacitinib 30 mg (UPA30) for 52 weeks. Assessments were by prior biologic failure. RESULTS: Of 1021 patients, 733 (71.8%) had prior biologic failure. Across outcomes and subgroups, upadacitinib-treated patients achieved higher rates vs placebo. During induction, upadacitinib had higher rates vs placebo for clinical remission based on stool frequency/abdominal pain score (without failure: 54.0% vs 28.3%; with failure: 42.2% vs 14.1%) and endoscopic response (without failure: 52.0% vs 16.2%; with failure: 35.7% vs 5.3%). In maintenance, the greatest treatment effect (upadacitinib vs placebo) was among patients with prior biologic failure treated with UPA30 (clinical remission without failure: 58.5% vs 32.7%; with failure: 42.5% vs 8.7%; endoscopic response without failure: 43.9% vs 17.9%; with failure: 38.9% vs 4.0%). Patients without vs with prior biologic failure had fewer adverse events. CONCLUSIONS: Upadacitinib led to higher absolutes rates of clinical and endoscopic outcomes in patients without vs with prior biologic failure. Patients treated with upadacitinib achieved greater rates of clinical and endoscopic improvements vs placebo, regardless of prior biologic exposure. CLINICALTRIALS: gov: NCT03345849, NCT03345836, NCT03345823.

Assessing the Plastisphere from Floating Plastics in the Northwestern Mediterranean Sea, with Emphasis on Viruses.

Plastics in the ocean create the "plastisphere", a diverse habitat hosting various life forms. Other than the pollution induced by plastics, the co-occurrence of primary producers, symbiotic organisms, decomposers, and pathogens within the plastisphere raises questions about how they influence the dynamics of marine ecosystems. Here, we used a shotgun DNA-sequencing approach to describe the species thriving on floating plastics collected in two Mediterranean sites. Our findings revealed many species of bacteria, eukaryotes, viruses, and archaea on each plastic. Proteobacteria was dominant (70% of reads in the entire dataset), with other groups such as Ascomycota fungi (11%) and Bacteroidetes (9%) also being represented. The community structure was not affected by the polymeric composition or the plastic shape. Notably, pathogenic Vibrio species, including V. campbelli, V. alginolyticus, and V. coralliilyticus, were among the most abundant species. Viruses, despite showing lower relative abundances, occurred in all samples, especially Herpesvirales, Caudovirales, and Poxviridae groups. A significant finding was the presence of the White Spot Syndrome virus (WSSV). This pathogen, responsible for devastating outbreaks in aquaculture systems, had not been previously reported in the marine plastisphere. Our study emphasizes the need for further investigation into the ecological and economic impacts of plastisphere organisms in the ocean.

Tardigrades in the marine plastisphere: New hitchhikers surfing plastics.

Tardigrades are remarkable microorganisms known for their extraordinary resilience in diverse environments, including extreme conditions such as outer space. They are known for their interactions with natural substrates in terrestrial and aquatic systems, but have remained largely unexplored in relation to marine plastics. This study aims to investigate the colonization of plastics, ranging from fossil fuel-based to bioplastics, in the coastal zones of four countries (Brazil, Ireland, France and Italy). Here, we report the first documented occurrence of tardigrades colonizing plastic substrates. We identified five amplicon sequence variants (ASVs) belonging to the Tardigrada phylum, specifically in a post-consumer polypropylene, in the coastal zone of Galway, Ireland. This discovery raises questions about the characteristics of different plastics influencing on tardigrades' adhesion. Tardigrades hitchhiking on plastics in the oceans could expand their habitat range, possibly displacing native species and altering trophic interactions, with potential consequences for the overall biodiversity.

The strong inverse association between plasma concentrations of soluble tumor necrosis factor receptors type 1 with adiponectin/leptin ratio in older women.

Complex inflammatory crosstalk between muscular and adipose organs during ageing is controlled by adipokines and myokines. The Adiponectin/Leptin ratio (A/L ratio) has proven to be a promising biomarker for identifying insulin sensitivity, cardiovascular risk and adipose tissue inflammation. Although the A/L ratio has been related to inflammatory conditions, its ability to associate with or indicate the behavior of other inflammatory mediators remains unknown. The present study aimed to verify the association between the A/L ratio and a panel of inflammatory biomarkers in community-dwelling older women. The plasmatic concentrations of adiponectin, leptin, resistin, brain-derived neurotrophic factor (BDNF), interferon-gamma (IFN-γ), interleukins 2, 4, 5, 6, 8 and 10, tumour necrosis factor (TNF) and its soluble receptors (sTNF-r) 1 and 2 were evaluated in 71 community-dwelling older women with 75 (±7) years. The A/L ratio was negative and inverse correlated with BNDF (r = -0.29; p = 0.01), IL-8 (r = -0.37; p = 0.001) and sTNFr- 1 (r = -0.98; p < 0.001) levels. A strong and inverse association, with proportional effect, between A/L ratio and sTNFr-1 concentrations was found (Adjusted R2 = 0.22; ß = -0.48; p > 0.001). It suggests that the presence of sTNFr-1 causes an inflammatory effect that affect cross-talk between muscle and adipose tissue, contributing to pro-inflammatory imbalance, which may have molecular and functional consequences. In addition, we provide insights into diagnostic biomarkers for inflammation, especially related to muscle wasting and intrinsic capacity in older people.

Association Between the Length of Leukocyte Telomeres and Functional Performance of Older Adults: Observational Study.

Despite current literature pointing to a link between shortened telomeres and aging, chronic diseases, and geriatric syndromes, the precise implications of this connection remain unclear. The aim of this exploratory, cross-sectional, observational study was to investigate the association between the relative telomere length (RTL) of peripheral blood leukocyte subtypes (mononuclear cells and granulocytes) and physical performance using the Short Physical Performance Battery (SPPB) in older adults. A cohort of 95 participants was recruited, which included men and women aged over 60 years (70.48 ± 5.5 years). It was found that mononuclear cell RTL was significantly lower than that of granulocytes (p < 0.0001). Moreover, individuals with good SPPB performance exhibited lower mononuclear cell RTL compared with those with moderate or poor performance. However, no significant differences were observed in granulocyte RTL between different SPPB performance groups. The global SPPB score showed an inverse correlation with mononuclear cell RTL, but this correlation was not present with granulocyte RTL. Similarly, the SPPB sit-to-stand domain correlated with mononuclear cell RTL, but no such correlation was found with granulocyte RTL. Our findings challenge conventional expectations, suggesting that shorter mononuclear cell RTL may be associated with favorable functional capacity. The variations in RTL between mononuclear cells and granulocytes highlight their distinct biological roles and turnover rates. A history of immune responses may influence mononuclear cell RTL dynamics, while telomerase activity may protect granulocyte RTL from significant shortening. The unexpected associations observed in mononuclear cell RTL emphasize the complex interplay between immune responses, cellular aging, and functional capacity in older adults.

Urinary incontinence in middle-aged and older women with hip and knee osteoarthritis: An outpatient study of frequency and risk factors.

AIMS: To investigate the frequency and the factors associated with urinary incontinence (UI) in a sample of middle-aged and older women with lower limb osteoarthritis (OA). METHODS: Women aged 50 years or older with clinical hip/knee OA diagnoses were recruited for this cross-sectional study. Self-reported UI and type, sociodemographic characteristics, medical conditions, physical activity level, anthropometric and body composition measurements, muscle strength, and physical function were assessed. Uni and multivariable logistic regression were used to investigate the factors associated with UI. RESULTS: Among 100 middle-aged and older women (mean 67.27 ± 8.77 SD years), 67% reported UI. In the UI group, 33% reported stress UI, 36% reported urgency UI, and 31% reported mixed UI. In the univariate analysis, age, level of physical activity, pulmonary disease, number of medications, body mass index (BMI), number of deliveries, and activity limitation were significantly associated with UI. In the multivariable analysis, older age (60-69 years OR: 4.91, 95% CI: 1.25-19.36; ≥70 years OR: 8.06, 95% CI: 1.96-33.22), compared to 50-59 years, morbid obesity (OR: 14.10, 95% CI: 1.36-146.48), compared to BMI < 30 kg/m2 , and activity limitation (OR: 5.31, 95% CI: 1.61-17.54), assessed as short physical performance battery ≤8, remained significantly associated with UI. CONCLUSIONS: UI was highly frequent among middle-aged and older women with hip/knee OA. Older age, activity limitation, and morbid obesity were independently associated with UI. Interventions targeting physical function and weight management must be considered to prevent and treat UI in this population.

Assessment of health-related quality of life in patients with Chagas cardiomyopathy using Minnesota living with heart failure questionnaire: A validation study.

OBJECTIVE: Chagas cardiomyopathy (ChC) is the most severe clinical form of Chagas disease and, in association with psychosocial factors, can compromise the health-related quality of life (HRQoL) of affected patients. To date, there is no specific instrument to assess the HRQoL of these patients, and the Minnesota Living with Heart Failure Questionnaire (MLwHFQ), specific for heart failure, is being used both in research and current clinical practice. Therefore, we aimed to verify the validity of the MLwHFQ in the assessment of HRQoL of patients with ChC. METHODS: Fifty patients with ChC (50.6 ± 10.1 years, NYHA I-III) were evaluated. The MLwHFQ, Short-Form of Health Survey (SF-36), Beck Depression Inventory (BDI), and Human Activity Profile (HAP) were applied. All patients underwent echocardiography and Cardiopulmonary Exercise Testing (CPET). RESULTS: The MLwHFQ score correlated with almost all SF-36 domains (with r-value ranging from -0.38 to -0.69), except pain (p = 0.118). The MLwHFQ score also correlated with the BDI score (r = 0.748; p < 0.001), HAP score (r = -0.558; p = 0.001), peak oxygen uptake (r = -0.352; p = 0.01), and left ventricular ejection fraction (r = -0.329; p = 0.021). There was no significant difference in the score found on the MLwHFQ among NYHA classes (p = 0.101), as well as between patients with systolic dysfunction (n = 30) and preserved cardiac function (n = 20) (p = 0.058). Similarly, there was no significant difference in the score found on the physical (p = 0.423) and mental (p = 0.858) components of SF-36 between patients with systolic dysfunction and preserved cardiac function (p = 0.271 and p = 0.609, respectively). There was also no difference in the mental component of SF-36 among NYHA classes (p = 0.673). However, the HRQoL using the physical component of SF-36 was worse in advanced NYHA classes (p = 0.014). CONCLUSION: MLwHF correlated with most SF-36 HRQoL domains, depressive symptoms, physical activity, and systolic function and seems to be valid in assessing the HRQoL of ChC patients.
