Roles of serum uric acid on the association between arsenic exposure and incident metabolic syndrome in an older Chinese population.

Growing evidences showed that heavy metals exposure may be associated with metabolic diseases. Nevertheless, the mechanism underlying arsenic (As) exposure and metabolic syndrome (MetS) risk has not been fully elucidated. So we aimed to prospectively investigate the role of serum uric acid (SUA) on the association between blood As exposure and incident MetS. A sample of 1045 older participants in a community in China was analyzed. We determined As at baseline and SUA concentration at follow-up in the Yiwu Elderly Cohort. MetS events were defined according to the criteria of the International Diabetes Federation (IDF). Generalized linear model with log-binominal regression model was applied to estimate the association of As with incident MetS. To investigate the role of SUA in the association between As and MetS, a mediation analysis was conducted. In the fully adjusted log-binominal model, per interquartile range increment of As, the risk of MetS increased 1.25-fold. Compared with the lowest quartile of As, the adjusted relative risk (RR) of MetS in the highest quartile was 1.42 (95% confidence interval, CI: 1.03, 2.00). Additionally, blood As was positively associated with SUA, while SUA had significant association with MetS risk. Further mediation analysis demonstrated that the association of As and MetS risk was mediated by SUA, with the proportion of 15.7%. Our study found higher As was remarkably associated with the elevated risk of MetS in the Chinese older adults population. Mediation analysis indicated that SUA might be a mediator in the association between As exposure and MetS.

Meta Analysis of the Correlation between Periodontal Health and Cognitive Impairment in the Older Population.

OBJECTIVE: To explore the correlation between periodontal health and cognitive impairment in the older population to provide the evidence for preventing cognitive impairment from the perspective of oral health care in older adults. METHODS: A comprehensive search was conducted in PubMed, Embase, the Cochrane Library, the Web of Science, the China National Knowledge Infrastructure, Wanfang Data, the China Science and Technology Journal Database, and the China Biomedical Literature Database, to include both cross-sectional and longitudinal cohort studies on the association between periodontal health and cognitive impairment in older adults. The search was completed in April 2023. Following quality assessment and data organization of the included studies, meta-analysis was performed using Review Manager 5.4. RESULTS: Twenty-two studies involving a total of 4,246,608 patients were included to comprehensively assess periodontal health from four dimensions (periodontitis, tooth loss, occlusal support, and masticatory ability), with the outcome variable of cognitive impairment (including mild cognitive impairment, Alzheimer's disease and all-cause dementia). Meta-analysis showed that, compared to those of periodontally healthy older adults, the risk of cognitive impairment in older adults with poor periodontal health, after adjusting for confounders, was significantly greater for those with periodontitis (OR=1.45, 95% CI: 1.20-1.76, P<0.001), tooth loss (OR=1.80, 95% CI: 1.50-2.15, P<0.001), compromised occlusal support (OR=1.87, 95% CI: 1.29-2.70, P=0.001), and reduced masticatory ability (OR=1.39, 95% CI: 1.11-1.75, P=0.005). The risk of cognitive impairment was higher in older adults with low-dentition than in those with high-dentition. Subgroup analysis revealed older individuals with fewer remaining teeth were at a higher risk of developing cognitive impairment compared to those with more remaining teeth, as shown by the comparison of number of teeth lost (7-17 teeth compared to 0-6 teeth) (OR=1.64, 95% CI: 1.13-2.39, P=0.01), (9-28 teeth compared to 0-8 teeth) (OR=1.13, 95% CI: 1.06-1.20, P<0.001), (19-28 teeth compared to 0-18 teeth) (OR=2.52, 95% CI: 1.32-4.80, P=0.005), and (28 teeth compared to 0-27 teeth) (OR=2.07, 95% CI: 1.54-2.77, P<0.001). In addition, tooth loss in older adults led to a significantly increased risk of mild cognitive impairment (OR=1.66, 95% CI: 1.43-1.91, P<0.001) and all-cause dementia (OR=1.35, 95% CI: 1.11-1.65, P=0.003), although the correlation between tooth loss and the risk of Alzheimer's disease was not significant (OR=3.89, 95% CI: 0.68-22.31, P=0.13). CONCLUSION: Poor periodontal health, assessed across four dimensions (periodontitis, tooth loss, occlusal support, and masticatory ability), represents a significant risk factor for cognitive impairment in older adults. The more missing teeth in older adults, the higher risk of developing cognitive impairment, with edentulous individuals particularly susceptible to cognitive impairment. While a certain degree of increased risk of Alzheimer's disease was observed, no significant association was found between tooth loss and the risk of developing Alzheimer's disease. Enhancing periodontal health management and delivering high-quality oral health care services to older adults can help prevent cognitive impairment.

Later-Life Cognitive Trajectories and Risk of Death: Results from a 6-Year Longitudinal Study of 7082 Chinese.

BACKGROUND AND OBJECTIVES: To identify cognitive decline trajectories in a Chinese elderly population, explore the associations between these trajectories and mortality, and further identify risk factors related to certain trajectories of cognitive decline. DESIGN: Prospective cohort study. SETTING: The group-based trajectory modeling and Cox proportional hazards models were conducted to explore the association between cognitive trajectory groups and mortality, while multinomial logistic regression models were constructed to estimate potential risk factors. PARTICIPANTS: We included 7082 participants aged 65 years or above in three consecutive but non-overlapping cohorts of the Chinese Longitudinal Healthy Longevity Survey with the Chinese version of the Mini-Mental State Examination up to 6 years. Participants were subsequently followed for a median (IQR) of 2.89 (1.38-3.12) years to obtain their survival status and date of death. MEASUREMENTS: Chinese version of the Mini-Mental State Examination was used to measure participants' cognitive function. RESULTS: Through use of group-based trajectory modeling, we determined three cognitive trajectory groups. Then, after adjusting for confounding factors, we found a monotonic and positive association between cognitive decline and mortality risk. Meanwhile, the association varied among elderly populations in different age groups and BMI categories, but did not differ by sex, smoking, drinking and exercising. Older seniors, females and those with poorer baseline cognitive function and less social participation tended to be more likely to be in the unfavorable trajectory groups. CONCLUSION: We found that the faster the cognitive decline, the higher the mortality, especially among those aged 65-79 years and those overweight. Our findings suggested the importance of implement better monitoring of the cognitive function of the elderly population.

Risky Business. Interventions to Prevent Aggression Against Health Workers From Patients at Risk: An Integrative Review.

AIM: To identify best practices to prevent violence against healthcare workers by patients at risk for aggression in the adult inpatient setting. DESIGN: An integrative review. METHODS: Conducted using the Johns Hopkins Evidence-based Practice for Nurses and Healthcare Professionals Model. Title and abstract screening on 4186 articles resulted in 156 for full text review. Full text screening yielded 14 articles that met inclusion criteria. DATA SOURCES: A search of the databases PubMed, CINAHL, Embase, and JBI from January 2019 to February 2023. RESULTS: The review revealed behavioural intervention teams, environmental changes, and coordinated communication plans were the most used strategies, however none demonstrated significant decreases in violence. CONCLUSIONS: Health systems can implement strategies shown to decrease the incidence of violence in healthcare settings globally. Lack of consistency in the evidence suggests the need for further research to assess mitigating strategies for violence against healthcare workers in inpatient hospital settings. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Patient safety is a cornerstone of nursing practice; however, healthcare workers need to feel safe in their work environment. Violent events are chronically underreported, ill defined, and when reported, do not address change in the practice setting. Identifying strategies to address escalating behaviour before it results in violence is crucial for everyone's safety. IMPACT: This integrative review exposes the scarcity of evidence available to address rising concerns about patients on healthcare provider violence (Type II) in the workplace. Although several assessment tools for identifying violent patients exist, evidence regarding prevention is woefully absent. The review highlights potential interventions for further study to equip healthcare workers to manage patients safely and effectively before an escalation occurs. REPORTING METHOD: PRISMA checklist for integrative reviews. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution was part of this review.

A Hybrid Concept Analysis of Frailty Among Older Adults Living in the Community.

AIM: To analyse the concept of frailty through a literature review and in-depth interviews. DESIGN: A hybrid model of concept analysis. METHODS: The theoretical phase identified 43 articles for reviewing the definition and measurement of frailty. Seven frail older adults were invited in the fieldwork phase for in-depth interviews. In the final analysis phase, results from the fieldwork and theoretical phases were integrated to obtain a final definition of frailty. RESULTS: Attributes of frailty were heterogeneous, involving dynamic/bidirectional, multidimensional and multiple systems. The antecedents of the concept were exposure to various stimuli and challenges in responding to these stimuli. Consequences included losing autonomy and adverse health outcomes. Four themes of frailty were identified based on the fieldwork data: 'accumulation of functional decline', 'powerlessness of coping with', 'vicissitudes of lived experience' and 'loss of autonomy and positivity'. CONCLUSIONS: The final definition of frailty was 'a dynamic and fluctuating process of powerlessness to manage biopsychosocial and environmental stimuli, involving functional decline and vicissitudes of life, which results in losing autonomy and positivity or adverse health outcomes'. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Characterising the definition of frailty is essential for nurses to address the lived experiences of older adults when providing person-centred care and for developing interventions that meet the needs of frail older adults. IMPACT: Since some discrepancies existed in the definition of frailty from individual perception of older adults, combined in-depth interviews with a theoretical literature review were used to provide comprehensive insight. This concept analysis provides guidelines of training for nurses and opportunities to improving quality of life for community dwelling older adults. REPORTING METHOD: N/A. PATIENT OR PUBLIC CONTRIBUTION: No Patient or Public Contribution.

A post-pandemic trend in the consumption of dietary supplements among residents of Lithuania.

OBJECTIVES: The consumption of dietary supplements might prevent the deficiency of necessary nutrients. On the other hand, in cases of overconsumption, adverse effects might occur. In Lithuania, the COVID-19 pandemic provoked an increase in the consumption of dietary supplements. The aim of this study was to reveal the post-pandemic trend of the consumption of dietary supplements among the working-age residents of Lithuania with respect to social and demographic factors and food selection criteria. METHODS: A cross-sectional observational study was performed. In total, using the same methods, 3,200 residents were surveyed: 1,600 in 2021 and 1,600 in 2022. Both samples were representative for Lithuania and included residents of Lithuania aged from 18 to 64 years. According to socio-demographic factors (sex, age, level of education, type of place of residence, marital status, number of family members, presence of children under 18 years old in the household, employment status, level of income), COVID-19 experience (presence of COVID-19 cases among friends or relatives, severeness of COVID-19) and food selection criteria (health strengthening, other) the prevalence of the consumption of dietary supplements was compared between the samples. RESULTS: The consumption of dietary supplements accounted for 78.1% and 71.6% of the respondents in 2021 and 2022, respectively (p < 0.001). After the COVID-19 pandemic, the prevalence of the consumption of dietary supplements decreased in the majority of social and demographic groups analysed in this article (p < 0.05). The consumption of dietary supplements remained unchanged among those who selected foods for health strengthening (p = 0.098). CONCLUSIONS: The prevalence of the consumption of dietary supplements decreased after the COVID-19 pandemic in most social and demographic groups except those who selected foods for health strengthening.

"I Do Not Believe We Should Disclose Everything to an Older Patient": Challenges and Ethical Concerns in Clinical Decision-Making in Old-Age Care in Ethiopia.

Clinical decision-making in old-age care is a complex and ethically sensitive process. Despite its importance, research addressing the challenges of clinical decision-making in old-age care within this cultural context is limited. This study aimed to explore the challenges and ethical concerns in clinical decision-making in old-age care in Ethiopia. This qualitative study employed an inductive approach with data collected via semi-structured interviews with 20 older patients and 26 health professionals recruited from healthcare facilities in Ethiopia. Data were analysed using reflexive thematic analysis. Our analysis identified three key themes. First, participants highlighted perceptions that older patients' religious beliefs interfere with the clinical decisions both older patients and health professionals make. Second, older patients often receive limited information from health professionals about their diagnosis and treatment. Third, families of older patients appear to strongly influence clinical decisions made by older patients or health professionals. This research enhances the understanding of clinical decision-making in old-age care within Ethiopia, a context where such research is scarce. As a result, this study contributes towards advancing the deliberation of ethical dilemmas that health professionals who work with older patients in Ethiopia might face. A key implication of the study is that there is a need for more ethics and cultural competence training for health professionals working with older patients in Ethiopia.

Charting the Course of the Nursing Professional Identity: A Qualitative Descriptive Study on the Identity of Nurses Working in Care for Older Adults.

AIMS: To explore and describe the meaning of nurses working in care for older adults give to the nursing professional identity. DESIGN: A qualitative approach was taken. METHODS: Semi-structured interviews were conducted with 50 bachelor and vocational-educated nurses working in care for older adults. Interviews were conducted between December 2019 and May 2020. Data were analysed and interpreted through inductive content analysis. RESULTS: Five themes embody the meaning of the nursing professional identity of nurses who work in care for older adults. The five themes are: born to care: a lifelong motivation to nursing; nursing through the noise: dedication in a demanding profession; the silent backbone: caught in the crossfire of interdisciplinary teams; learning under pressure: the demand for expanded nursing expertise and against the current: the barriers to advocacy in nursing. CONCLUSION: The professional nursing identity of nurses working in care for older adults is multi-faceted. A personal dedication to patient care, where patients 'human' aspect is heavily valued, commits nurses to their profession and underscores their dedication to upholding the quality standard in nursing practice. IMPLICATIONS FOR THE PROFESSION: The older adults' nursing identity highlights that nursing deserves acknowledgement as a professional occupation. Nurses should speak to the public about their professional roles to improve the public view of older adult nursing. IMPACT: A clear understanding of the older adult nursing professional identity clarifies specific roles, experiences and expectations. This can help attract and retain nurses whose views of older adult nursing align with the nursing professional identity. This could help resolve nurse turnover and reduce shortages in older adult care. REPORTING METHOD: We adhered to Consolidated Criteria For Reporting Qualitative Research guidelines. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

"I've Got a Lot of Other Things I Do": The Nuances of Digital Engagement among Older People.

As Western society becomes increasingly digitally dependent and many older adults actively engage in the online world, understanding the experiences of those who largely do not use digital technology in their daily lives is crucial. Individual interviews were conducted (pre-pandemic) with 23 older adults who, based on self-identification, did not regularly use digital technology, exploring how their experiences as limited digital technology users may have impacted their daily lives. An iterative collaborative qualitative analysis demonstrated three main themes: internet concerns, frustrations with digital technology, and conflicting motivators to use digital technology. Findings suggest that addressing digital concerns and providing effective digital skill learning opportunities may encourage some older adults to become more digitally engaged. However, as people, including older adults, can be uninterested in using these technologies, organizations and institutions should work to offer ways to support people of all ages who are not engaged online.

Research Participation and Feedback: Perception of Adolescents and Young Adults Living with HIV in Lagos, Nigeria.

BACKGROUND: Evidence-based research remains the cornerstone in changing the narrative of wholesome health among Adolescents and Young Adults Living with HIV (AYALHIV). However, little is known about the perceptions of AYALHIV in research participation and outcomes, in low- and middle-income countries, especially in sub-Saharan Africa. This study describes the perception of AYALHIV in research participation and outcome in Lagos, Nigeria. METHODS: The study population was drawn from a cohort of participants in a cross-sectional study at the Nigerian Institute of Medical Research. The survey questions were on perceptions of the importance of research participation, the frequency, understanding of participation in research, the interest in the outcome, the knowledge of the interpretation of the outcome and the willingness to participate in future studies. Data obtained was analyzed using SPSS version 26.0. RESULTS: The mean age of the AYALHIV was 15.7(±3.1) years, with a male-to-female ratio of (0.8:1), and 85.7% on antiretroviral drugs for at least five years. Seventy-two percent (46/63) have been involved in previous studies at least once, with only 27% (17/63) informed on the outcome of the research they have ever participated. Only 30% (19) of participants understood they were involved in research, with 92% interested in the study outcome. 87.3% (55) will request more information before participating in future research activities. CONCLUSION: Educating AYALHIV on research participation is important in promoting concerted efforts by researchers towards improving engagement, patient-centred care, and research dissemination.

CONTEXTE: La recherche fondée sur des données probantes reste la pierre angulaire du changement du discours sur la santé saine chez les adolescents et les jeunes adultes vivant avec le VIH (AYALHIV). Cependant, on sait peu de choses sur les perceptions de l'AYALHIV dans la participation et les résultats de la recherche, dans les pays à revenu faible et intermédiaire, en particulier en Afrique subsaharienne. Cette étude décrit la perception d'AYALHIV dans la participation et les résultats de la recherche à Lagos, au Nigéria. METHODES: La population m'étudiée a été tirée d'une cohorte de participants à une étude transversale menée à l'Institut nigérian de recherche médicale. Les questions de l'enquête portaient sur les perceptions de l'importance de la participation à la recherche, la fréquence, la compréhension de la participation à la recherche, l'intérêt pour les résultats, la connaissance de l'interprétation des résultats et la volonté de participer à des études futures. Les données obtenues ont été analysées à l'aide de SPSS version 26.0. RESULTATS: L'âge moyen des AYALHIV était de 15,7 (± 3,1) ans, avec un ratio hommes/femmes de (0,8 : 1) et 85,7 % prenaient des médicaments antirétroviraux depuis au moins cinq ans. Soixantedouze pour cent (46/63) ont participé à des études antérieures au moins une fois, et seulement 27 % (17/63) sont informés des résultats de la recherche à laquelle ils ont déjà participé. Seulement 30 % (19) des participants comprenaient qu'ils étaient impliqués dans la recherche, et 92 % d'entre eux étaient intéressés par les résultats de l'étude. 87,3 % (55) demanderont plus d'informations avant de participer à de futures activités de recherche. CONCLUSION: Éduquer AYALHIV sur la participation à la recherche est important pour promouvoir les efforts concertés des chercheurs en vue d'améliorer l'engagement, les soins centrés sur le patient et la diffusion de la recherche. MOTS CLES: VIH, Adolescent, Jeunes adultes, Perception, Recherche.

Schizotypal traits and their relationship to reading abilities in healthy adults.

Schizotypal traits (i.e., personality characteristics that range from mild eccentricities to more pronounced schizophrenia-like perceptions, thought patterns, and behaviours) have been associated with a variety of cognitive impairments, including difficulties in language processing. Although these difficulties span several aspects of language (e.g., semantic processing, verbal fluency, visual word recognition), it is unclear whether reading abilities are also affected. Thus, the current study employed the Schizotypal Personality Questionnaire (SPQ) - Brief (Raine and Benishay, 1995) to examine how schizotypal traits impact both word-level and text-level reading skills (using a battery of standardized assessments) in a sample of healthy young adults. We found some evidence that higher schizotypal traits, specifically, increased Disorganized factor scores (reflecting aberrant thinking, communication patterns, and behaviour), were associated with reduced word-level reading abilities. However, this finding did not remain significant after correcting for multiple comparisons. Overall, our study suggests that reading may be another aspect of language affected by schizotypal traits, although additional research (with greater power) is needed to further explore and confirm this finding.

Global burden of chronic kidney disease in adolescents and young adults, 1990-2019: a systematic analysis for the Global Burden of Disease Study 2019.

Background: The global status of chronic kidney disease (CKD) is underestimated, particularly the burden on adolescents and young adults (early-onset, aged 15-39). Objective: We aim to investigate the pattern and trend of early-onset CKD from 1990 to 2019. Methods: We analyzed age-specific rates of early-onset CKD incidence, death, and disability-adjusted life years (DALY) using Global Burden of Disease Study 2019 data. We examined the global, regional, national, gender-based, age group-based, and temporal changes of early-onset CKD burden from 1990 to 2019, as well as proportional DALY attributions of various risk factors. Results: From 1990 to 2019, the global age-specific incidence rate (per 100,000 population) significantly increased from 25.04 (95% confidence interval 18.51, 31.65) to 32.21 (23.73, 40.81) for early-onset CKD. However, the global age-specific death rate significantly decreased from 2.96 (2.76, 3.15) to 2.86 (2.61, 3.11), and the age-specific DALY rate remained stable. Regarding sociodemographic indexes (SDI), countries with middle SDI had the highest incidence rates and the fastest increasing trends, while those with low and low-middle SDI experienced the highest death and DALY rates. Women had a generally higher age-specific incidence rate than men, whereas men showed higher age-specific death and DALY rates. In addition, the burdens of CKD increased with age among adolescents and young adults. Moreover, the main attributable risk factors for DALY of early-onset CKD were high systolic blood pressure (SBP), fasting plasma glucose (FPG), and body mass index (BMI). Conclusion: The age-specific incidence rate of early-onset CKD increased significantly from 1990 to 2019, and the age-specific DALY rate remained stable. High SBP, high FPG, and high BMI were the primary risk factors. Targeted prevention and healthcare measures should be developed considering age, gender, and region.

Visual and Demographic Risk Factors for Falls and the Impact of Cataract Surgery in Elderly Patients.

Purpose: To evaluate the effect of cataract surgery and visual impairment and the associated risk factors on the frequency of falls among older adults in northeast Iran. Methods: This cross-sectional study, conducted between 2019 and 2020, analyzed the potential risk factors of falling in older adults over 50 years of age. To this end, 380 patients were randomly selected by convenience sampling and classified into two groups: those who had undergone cataract surgery in the last 12 months (surgery group) and those who had not (cataract group). The data were collected from the medical records and face-to-face interviews, and logistic regression was used to identify potential risk factors for falling. Results: The frequency of falls in the cataract and surgery groups was 18.9% and 11.6%, respectively. The mean decimal visual acuity of the dominant eye was significantly lower in the cataract group than in the surgery group (P < 0.001). There were no significant differences in the mean number of medications used, Charlson Comorbidity Index score, Instrumental Activities of Daily Living score, and 10-Meter Walk Test speed between the two groups. According to the results of backward logistic regression, taking more than four medications per day and slow gait speed were the most important factors influencing the frequency of falls in older adults. Conclusion: Logistic regression analysis indicated that undergoing cataract surgery is not a significant protective factor against falls. However, older adults in the surgery group experienced fewer falls than in the other group. Besides, the results suggest that taking more than four medications daily and having a slow gait speed are significant fall risk factors.

Polypharmacy and potentially inappropriate medicine use in older adults with cancer: a multicenter cross-sectional study in Northwest Ethiopia oncologic centers.

Background: Most patients with cancer have comorbid conditions that necessitate advanced medical treatment. Polypharmacy (PP) and potentially inappropriate medicine (PIM) use is common among older adult patients with cancer. Not much research has been conducted on PP and PIM use among older adult patients with cancer in Ethiopian oncology centers. Therefore, this study aimed to evaluate the prevalence and determinants of PP and PIM use among older adults with cancer in Northwest Ethiopia oncology centers using the American Geriatrics Society (AGS) 2019 updated Beers criteria. Methods: This multicenter cross-sectional study was conducted among older adult patients with cancer from July 15-December 30, 2023 in Northwest Ethiopian oncology centers. The use of at least one drug included in the 2019 Beers criteria revisions was classified as potentially inappropriate medication use. To identify the factors influencing PP and PIM use, logistic regression analysis was performed. Results: Of the 310 samples aproched, 305(98.4% response rate) participated in the study. The prevalence of PP and PIM use were 70.2% (95% CI 64.9-75.1) and 63.0% (95% CI 57.4-68.8) respectively. Being female AOR:3.6; 95% CI:1.7-7.8; p = 0. 001, advanced age [(70-74 years) AOR:3.9; 95% CI:1.2-6.7; p = 0.046 and ≥75 years AOR:3.8; 95% CI:1.7-8.4; p = 0.0028], abnormal body weight (underweight AOR:5.5; 95% CI:1.5-9.6; p = 0.019, overweight AOR:5.1; 95% CI:1.5-7.3; p = 0.01 and obese AOR:5.6; 95% CI:1.5-9.3; p = 0.021) and comorbidities AOR:3.5; 95% CI:1.7-8.3; p = 0.0032 were statistically significant factors for PP. Advanced age [(70-74 years) AOR:5.5; 95% CI:1.4-9.8; p = 0.015 and ≥75 years AOR:3.3; 95% CI:1.5-7.1; p = 0.002)] and polypharmacy; AOR:7; 95% CI:3.4-9.4; p = 0.001 were statistically significant factors for PIM use. Conclusion: Polypharmacy and potentially inappropriate medicine use were prevalent among older adult patients with cancer. Ensuring safe medicines prescription practices for older patients with cancer requires understanding the issue, stopping unwarranted treatment, and replacing it with less toxic, age-appropriate medicines.

Association between systemic immune-inflammation index and cataract among outpatient US adults.

Background: While several studies have noted a higher SII correlates with multiple diseases, research on the association between SII and cataract remains limited. Our cross-sectional study seeks to examine the association between SII and cataract among outpatient US adults. Methods: This compensatory cross-sectional study utilized NHANES data from 1999 to 2008 cycles, conducting sample-weighted multivariate logistic regression and stratified analysis of subgroups. Results: Among 11,205 adults included in this study (5,571 [46.2%] male; 5,634 [53.8%] female), 2,131 (15.2%) had cataract and 9,074 (84.8%) did not have cataract. A fully adjusted model showed that SII higher than 500 × 109/L was positively correlated with an increased risk of cataracts among women (OR, 1.27; 95% CI, 1.02-1.59) (p = 0.036). However, no difference was found in the men subgroup, and there was no significant interaction between SII and sex. Conclusion: Our results indicated that a SII higher than 500 × 109/L was positively correlated with an increased risk of cataracts in women. This study is the first to specifically investigate the impact of a high SII on cataract risk in outpatient adults in the United States. By effectively addressing inflammation, it is possible to mitigate cataract progression and significantly enhance patient outcomes.

Prevalence of Diastolic Dysfunction in Critically Ill Patients Admitted to Intensive Care Unit from a Tertiary Care Hospital: A Prospective Observational Study.

Aim: Critically ill individuals may have left ventricular diastolic dysfunction (LVDD) which can prolong their intensive care unit (ICU) stay. The purpose of this study was to determine the prevalence of LVDD in critically ill adult patients requiring mechanical ventilation in ICU, the effect of LVDD on 28-day survival, and weaning from mechanical ventilation. Methodology: A total of 227 adults who had been on mechanical ventilation for more than 48 hours in an ICU were recruited for this study. The study's parameters were recorded on the third day of mechanical ventilation using a low-frequency phased array probe. A simplified definition of LVDD in critically ill adults was utilized to determine the presence or absence of LVDD. Weaning failure and 28-day mortality were noted. Results: The prevalence of LVDD in adults requiring mechanical ventilation in the ICU was found to be 35.4% (n = 79). Patients with LVDD had the odds of having a 28-day mortality increase by 7.48 (95% CI: 3.24-17.26, p < 0.0001). Patients with LVDD had the odds of having weaning failure increase by 5.37 (95% CI: 2.17-13.26, p = 0.0003). Conclusion: Measures should be taken to detect critically ill adults with LVDD with systolic dysfunction or heart failure with preserved ejection fraction early so that their fluid balance, myocardial contractility, and afterload can be optimized to minimize their morbidity and mortality. Highlights: Critically ill adults with LVDD may have adverse outcomes. Hence, protocol should be in place for diagnosing LVDD early in critically ill adults thereby, measures can be taken to minimize morbidity in those patients.

Ability of Heart Rate Recovery and Gait Kinetics in a Single Wearable to Predict Frailty: Quasiexperimental Pilot Study.

BACKGROUND: Aging is a risk factor for falls, frailty, and disability. The utility of wearables to screen for physical performance and frailty at the population level is an emerging research area. To date, there is a limited number of devices that can measure frailty and physical performance simultaneously. OBJECTIVE: The aim of this study is to evaluate the accuracy and validity of a continuous digital monitoring wearable device incorporating gait mechanics and heart rate recovery measurements for detecting frailty, poor physical performance, and falls risk in older adults at risk of falls. METHODS: This is a substudy of 156 community-dwelling older adults ≥60 years old with falls or near falls in the past 12 months who were recruited for a fall prevention intervention study. Of the original participants, 22 participants agreed to wear wearables on their ankles. An interview questionnaire involving demographics, cognition, frailty (FRAIL), and physical function questions as well as the Falls Risk for Older People in the Community (FROP-Com) was administered. Physical performance comprised gait speed, timed up and go (TUG), and the Short Physical Performance Battery (SPPB) test. A gait analyzer was used to measure gait mechanics and steps (FRAIL-functional: fatigue, resistance, and aerobic), and a heart rate analyzer was used to measure heart rate recovery (FRAIL-nonfunctional: weight loss and chronic illness). RESULTS: The participants' mean age was 74.6 years. Of the 22 participants, 9 (41%) were robust, 10 (46%) were prefrail, and 3 (14%) were frail. In addition, 8 of 22 (36%) had at least one fall in the past year. Participants had a mean gait speed of 0.8 m/s, a mean SPPB score of 8.9, and mean TUG time of 13.8 seconds. The sensitivity, specificity, and area under the curve (AUC) for the gait analyzer against the functional domains were 1.00, 0.84, and 0.92, respectively, for SPPB (balance and gait); 0.38, 0.89, and 0.64, respectively, for FRAIL-functional; 0.45, 0.91, and 0.68, respectively, for FROP-Com; 0.60, 1.00, and 0.80, respectively, for gait speed; and 1.00, 0.94, and 0.97, respectively, for TUG. The heart rate analyzer demonstrated superior validity for the nonfunctional components of frailty, with a sensitivity of 1.00, specificity of 0.73, and AUC of 0.83. CONCLUSIONS: Agreement between the gait and heart rate analyzers and the functional components of the FRAIL scale, gait speed, and FROP-Com was significant. In addition, there was significant agreement between the heart rate analyzer and the nonfunctional components of the FRAIL scale. The gait and heart rate analyzers could be used in a screening test for frailty and falls in community-dwelling older adults but require further improvement and validation at the population level.

Effects of shuttle balance exercises on gait speed, postural control, and quality of life in older males: A randomized controlled trial.

BACKGROUND AND PURPOSE: Enhancing physical function and quality of life in older adults at higher risk of falls is challenging because of the lack of established interventions. This study examines the impact of a 6-week balance training program using the shuttle balance device on gait speed, postural control, and quality of life in older men. METHODS: This single-blinded randomized controlled trial was conducted in a research laboratory. Thirty-two participants aged ≥60 years were randomly assigned to either an experimental group (EG; n = 16) or a control group (CG; n = 14). The EG participated in a 6-week shuttle balance exercise program, while the CG maintained regular physical activity routines. The main outcome measures included gait speed (assessed via the timed up and go test), postural control (assessed via center of pressure data on a force plate), and quality of life (evaluated using the SF-36 questionnaire). RESULTS: Post-intervention, the EG showed significant improvements compared with the CG (p < 0.05). The 95% confidence intervals for the differences between groups were as follows: closed eyes (CE) mean velocity (-39.07, -0.13), CE sway area (-48.86, -0.18), SF-36 total score (9.01, 16.81), SF-36 physical functioning (7.00, 24.81), SF-36 physical role functioning (1.80, 27.57), SF-36 pain (15.01, 36.82), SF-36 general health state (7.48, 26.08), SF-36 vitality (5.60, 28.35), and SF-36 mental health (0.21, 21.12). DISCUSSION: A 6-week shuttle balance training program significantly improves postural control and quality of life in older males. These findings suggest the potential effectiveness of shuttle balance exercises in enhancing physical function and well-being in this population. Further research is needed to validate these findings and explore the long-term effects with larger sample sizes.

Risk factors behind the increase of early-onset cancer in Italian adolescents and young adults: An investigation from the Italian AYA Working group.

The incidence of early-onset cancers in adolescents and young adults (AYA) has been increasing worldwide since the 1990s. In Italy, a significant increased rate of 1.6 % per year has been reported for early-onset cancers among females between 2008 and 2016. This is mainly attributable to melanoma, thyroid, breast and endometrial cancer. The aim of our work was to describe temporal trends of the main established lifestyle risk factors (tobacco use, alcohol consumption, obesity, physical inactivity, dietary westernization and reproductive factors) over the last 20 years in the Italian AYA population. Available data on behavioural risk factors, individual and household daily life have been obtained and elaborated from PASSI, ISTAT and Eurostat reports. Lowering age of smoking initiation, an increase in alcohol drinkers among young females, and an obesity and overweight epidemic, particularly among children and adolescents as a result of physical inactivity and dietary habits, may be contributing factors behind this cancer epidemic, especially among females. In-depth investigations are needed to understand the exact role of each contributing factor, the effects of exposure to nicotine-containing products and environmental factors such as endocrine disruptors that could play a role in this phenomenon.

Medical Suitability and Willingness for Living Kidney Donation Among Older Adults.

RATIONALE & OBJECTIVE: The benefits of kidney transplantation compared to treatment with dialysis, including in older adult, are primarily limited by the number of donated kidneys. We studied the potential to expand the use of older living kidney donors. STUDY DESIGN: Secondary analysis of the Berlin Initiative Study, a population-based cohort. SETTING: & Participants: 2069 adults aged ≥70 years in Germany. EXPOSURES: Age and sex. OUTCOMES: Suitability for living donation assessed by the absence of kidney-related exclusions for donation including albuminuria and low estimated glomerular filtration rate (eGFR) as well as absence of other medical exclusions. Willingness for living and deceased kidney donation assessed by participant survey. ANALYTICAL APPROACH: Descriptive analysis. RESULTS: Among the 2069 participants (median age 80 years, 53% women, median eGFR 63 ml/min/1.73m2), 93% had ≥1 medical contraindication for living donation at study entry unrelated to eGFR or albuminuria. Using two published eGFR and albuminuria thresholds for donor acceptance, 38% to 54% of participants had kidney-related exclusions for donation. Among the 5% to 6% of participants with neither medical nor kidney-related exclusions for living donation at baseline, 11% to 12% remained suitable for donation during 8 years of follow-up. Willingness for living or deceased donation was high (73% and 60%, respectively). LIMITATIONS: GFR was not measured and medical exclusions unrelated to eGFR and albuminuria were assessed using a cohort database complemented by claims data. CONCLUSIONS: One in twenty older adults were potentially suitable for living kidney donation and willingness for living donation was high. Further studies are warranted to define the feasibility of expanding living kidney donation among older adults.
