Abstract 4124506: Short Physical Performance Battery as a Marker of Severity and Predictor of Clinical Outcomes in Transthyretin Amyloid Cardiomyopathy (ATTR-CM)

Background: ATTR-CM has an age dependent prevalence and is a disorder that almost exclusively affects older adults. Objective evaluations of function are critical to assessing and managing ATTR-CM in older adults. The short physical performance battery (SPPB) is a valid measure of functional capacity that predicts morbidity and mortality in older adults but its utility in ATTR-CM remains unknown. Aims/hypothesis: To establish SPPB as a useful marker of disease severity and predictor of outcomes in ATTR-CM. We hypothesized that SPPB scores would correlate with validated markers of ATTR-CM severity and improve clinical prediction. Methods: This is a retrospective analysis of patients referred to the Columbia University Cardiac Amyloid Program. Patients were stratified into low (SPPB 0-6), moderate (7-9), and high (10-12) cohorts based on initial SPPB score and baseline characteristics were compared between groups. Cox proportional hazard models and Kaplan Meier (KM) curves were generated to assess associations with mortality as well as a composite of death and cardiovascular (CV) hospitalization in follow-up. Results: A total of 263 patients, age 78 years (IQR 73, 84), 86% male, 22% with ATTRv (variant) and 78% with ATTRwt (wild type) were studied. SPPB showed no limitation in 59%, mild limitation in 33%, and severe limitation in 8%. Lower SPPB was associated (p <0.05) with older age, prior stroke/TIA, shorter 6-minute walk test, elevated NT-proBNP and HS-troponin, worse quality of life metrics on Kansas City Cardiomyopathy Questionnaire, more advanced NYHA and Mayo stages, and higher Columbia scores. On multivariate regression (adjusted for age, sex, genotype, NYHA), SPPB was independently associated with the composite of mortality and CV hospitalization, with each point increase corresponding to 13% lower incidence of the outcome (HR 0.87, p=0.01). Chair stands score, one of three SPPB subdomains, was independently associated with the composite and mortality. KM curves showed significant association with SPPB and both the composite and mortality (Fig. 1). Conclusions: SPPB score is a marker of ATTR-CM severity, associated with validated biomarkers and staging systems, and independently predicts clinical outcomes.

Abstract 4138730: Analysis of Coronary Artery Disease and COPD Mortality in Older Adults in the United States, 1999-2020: CDC Data on Geographic, Gender, and Racial Trends in Mortality

Background: The coexistence of coronary artery disease (CAD) and Chronic Obstructive Pulmonary Disease (COPD) represents a major health challenge for older adults in the United States. This study designed to examine the variations in mortality rates associated with CAD and COPD among individuals aged 65 and above from 1999 to 2020. Methods: Using the CDC WONDER database, a retrospective analysis was conducted on death certificate data from 1999 to 2020. Age-adjusted mortality rates (AAMRs) per 100,000 persons were calculated, and trends were evaluated using Average Annual Percentage Change (AAPC) and Annual Percentage Change (APC). The data were stratified by year, sex, race/ethnicity, and geographical region. Results: Between 1999 and 2020, coronary artery disease (CAD) and Chronic Obstructive Pulmonary Disease (COPD) were responsible for 881,875 deaths among adults aged 65 and older in the United States. The majority of these deaths occurred in medical facilities (40.3%) and in the decedents' homes (28.3%). The overall Age-Adjusted Mortality Rate (AAMR) decreased from 119.4 in 1999 to 86.9 in 2020, with an Annual Percent Change (APC) of -1.65 (p < 0.000001). Notably, AAMRs moderately decreased from 1999 to 2018 (APC: -2.13, p = 0.025195), followed by a significant increase from 2018 to 2020 (APC: 2.95, p = 0.296341). Men had notably higher AAMRs than women (men: 139.8; women: 67.4), with both sexes experiencing almost equal declines over the study period. In terms of race, Whites had the highest AAMRs (106.5), followed by Native Americans (87.3), Blacks (60.7), Hispanics (51.0), and Asians (30.4). While all racial groups experienced decrease in AAMR , the decline was more signficance in Asians [AAPC: -3.26, (CI: -4.30 to -2.27) (p-value < 0.000001)]. Geographically, AAMRs varied widely among states, with the highest mortality rates observed in the Midwestern region. Nonmetropolitan areas generally had higher AAMRs than metropolitan areas, and both showed decreases from 1999 to 2020, with greater declines in metropolitan areas. Figure 1 Conclusion: This research emphasizes the temporal trends and demographic discrepancies in mortality rates linked to CAD and COPD among older adults aged 65 and above in the United States. Despite an overall decrease in mortality rates, the recent rise necessitates additional investigation and focused interventions to address inequalities and improve outcomes in affected demographic groups.

Mortality in older adults with epilepsy: An understudied entity.

Despite the recognition of Sudden Unexpected Death in Epilepsy (SUDEP) and other risks of premature mortality in people with epilepsy (PWE), mortality in older PWE remains an understudied entity. This review provides a comprehensive overview of the multifaceted causes of premature mortality in older adults with epilepsy and emphasizes the need for targeted interventions to reduce mortality and enhance the quality of life in this vulnerable population. It underscores the heightened prevalence of epilepsy among older adults and the interplay of intrinsic and extrinsic factors contributing to their mortality. Further, this paper delves into the nuances of diagnosing SUDEP in older adults and the underestimation of its incidence due to misclassification and lack of standardized protocols. Factors such as frailty, comorbidities, and the bidirectional relationship between epilepsy and conditions such as dementia and stroke further compound the mortality risks. Key factors, including status epilepticus, comorbid conditions (such as cardiovascular diseases, cerebrovascular events, and neurodegenerative disorders), and external causes like accidents, falls, and suicide, are discussed. It also examines the implications of anti-seizure medications, particularly polypharmacy, and their adverse effects on this population. Future directions include implementing enhanced diagnostic protocols, developing treatment plans, and integrating real-time monitoring technologies to reduce the risk of sudden death and multifaceted premature mortality in this patient population. Increasing awareness among healthcare providers and families about the risks and management of epilepsy in older adults, along with fostering collaborative research efforts, is essential to improve mortality outcomes. PLAIN LANGUAGE SUMMARY: There is a heightened risk of mortality in older people with epilepsy due to many causes unique to their population. Despite the risk, Sudden Unexpected Death in Epilepsy and early mortality in older adults with epilepsy are underestimated. Unique contributing factors include comorbid conditions like dementia, stroke, and frailty, adverse effects from polypharmacy, and increased risks of cardiovascular complications and external injuries such as falls and suicide. A careful consideration of all these factors can help mitigate the mortality in older adults with epilepsy.

Necrotizing Pneumonia: A Practical Guide for the Clinician

While rare, necrotizing pneumonia is a severe and potentially life-threatening manifestation of lung parenchyma infection. Initially documented in the 1940s, it was a significant contributor to mortality rates in both adults and children, with figures reaching up to 45%. Despite being a disease described in the literature for decades, data on the management of necrotizing pneumonia remain limited. Most available information comes from retrospective observational cohort studies. This article aims to provide a comprehensive summary of the existing literature on the subject.

Synergistic effects of elevated temperature with pesticides on reproduction, development and survival of dung beetles.

In times of global change, high temperatures can increase the negative effects of pesticides and other stressors. The goal of this study was to evaluate, under controlled laboratory conditions, the effect of a moderate increase in temperature in combination with ivermectin (an antiparasitic medication used in cattle that is excreted in dung), an herbicide, and parasitic pressure, on the reproductive success, development time and adult survival of dung beetles Euoniticellus intermedius. Whereas high temperature increased the number and proportion of emerged offspring, it had synergistic negative effects in combination with the ivermectin, herbicide and parasite treatments. Moreover, high temperature in combination with ivermectin and with parasitism caused a synergistic increase of adult offspring mortality and, in combination with the herbicide, it synergistically accelerated development. These results indicate that high temperatures can enhance the negative effects of other stressors and act synergistically with them, harming dung beetles, a group with high ecological and economic value in natural and productive ecosystems. Although adult sex ratio was not affected by experimental treatments, contrasting responses were found between males and females, supporting the idea that both sexes use different physiological mechanisms to cope with the same environmental challenges. The effects that combined stressors have on insects deepen our understanding of why we are losing beneficial species and their functions in times of drastic environmental changes.

Toxicity and residual activity of insecticides to Grapholita molesta (Lepidoptera: Tortricidae) in apple orchards: implications for insecticide resistance management.

Organophosphate (OP) insecticides have been used to control Grapholita molesta (Busck, 1916) in Brazil since 1990. However, the evolution of pest insecticide resistance and toxicological reassessments has led to the replacement of OPs with other chemical groups. This study evaluated the toxicity of the insecticides abamectin + cyantraniliprole (1.1 + 3.7g a.i./100L-1), acetamiprid + etofenproxi (9.1 + 16.5g a.i./100L-1), emamectin benzoate (0.5g a.i./100L-1), Sophora flavescens (Fabales: Fabaceae) (22.8g a.i./100L-1), phosmet (87.5g a.i./100L-1), and indoxacarb (11.2g a.i./100L-1) to eggs, larvae, and adults of G. molesta. Additionally, the residual activity of these insecticides in apple orchards was assessed, and the diagnostic concentration for resistance monitoring was estimated using LC99 values (Lethal Concentration that causes 99% mortality in a susceptible population). In larval studies, all insecticides resulted in mortality rates of more than 90%. The insecticide acetamiprid + etofenproxi reduced larval hatching by 99%. This insecticide with phosmet and Sophora flavescens caused over 80% adult mortality and had a 14-day residual activity in apple orchards. The estimated LC99 (μg.ml-1) for resistance monitoring were 1.75 (indoxacarb), 6.45 (metaflumizone), 9.10 (acetamiprid + etofenproxi), 9.67 (Sophora flavescens), 36.13 (phosmet), and 45.61 (abamectin + cyantraniliprole). The insecticides evaluated have high toxicity for G. molesta, being new tools for integrated pest management and for insecticide resistance management in apple orchards.

Comparative analysis of the targets for reducing adult population mortality by 2024

Introduction. Currently, in the Russian Federation there are realized national projects “Healthcare” and “Demography” aimed at reducing the mortality. For implementation at the regional level in Moscow, there have been developed regional programs with appropriate regional indicators. The purpose of the study is to assess the degree of achievement of the targets of national, federal and regional adult mortality rates. Materials and methods. The study is based on a comparative analysis of targets and actual statistical data. Results. In Moscow and in Russia, there is a decrease in mortality from all causes, diseases of the circulatory system, myocardial and cerebral infarction, neoplasms. Despite the increase in the level in 2020–2021 due to the pandemic, in 2022, mortality rates returned to the pre-pandemic period and have a tendency to further decrease. Current trends point to the high achievability of targets in Moscow, while in the country, most indicators have a chance of not being achieved. In Moscow there is noted a higher cancer mortality rate i to which a significant contribution may be made by cancer patients from other Russian regions who receive medical care in federal cancer centers located in Moscow and who died on its territory. Research limitations. Standardized mortality rates of the population were calculated in the FAISS internal use program. Conclusion. The implementation of national, federal and regional projects has had a positive impact on the effectiveness of demographic policy to reduce mortality.

The impact of early surgery on mortality and functional recovery in older adults with traumatic intracranial lesions: a propensity score-based analysis.

There is skepticism about the benefit of surgery in elderly patients affected by traumatic brain injury (TBI) due to the negative effect of age on the outcome and surgical complications. However, there are few studies that have investigated differences in patient's outcome between surgically and conservatively managed patients after adjusting for the imbalance in preinjury characteristics and clinical and radiological features. The primary aim of this study was to evaluate the effect of early surgery on mortality and functional recovery in a cohort of older adults with acute traumatic intracranial lesions after adjustment by Propensity Score (PS) matching. MATERIALS AND METHODS: We conducted a retrospective cohort study on older adult patients (≥ 65 years) admitted for TBI between 2013 and 2023 to a single level 1 trauma center. Patients were categorized based on whether they underwent early surgery (< 48h after TBI) for a space-occupying lesion evacuation. PS model was constructed based on age, frailty, comorbidities (Charlson comorbity index and American Society of Anaesthesiologists score), anticoagulants, hypoxia, shock, pupillary abnormalities and GCS motor response upon admission, midline shift, basal cistern effacement, volume of subdural and intracerebral hematomas, and limitation of life-sustaining treatment decisions.The effect of early surgery on 30-day mortality and unfavorable functional outcomes (GOSE 1-3) at 6 and 12 months were investigated after matching by paired test. We identified and reviewed 301 patients who met all inclusion criteria and contained no exclusions. After matching, 62 patients (31 pairs of conservative and surgical patients) remained as the matched datasets. Our key finding was that older adult TBI patients who underwent early surgery had a statistically significant reduction in the risk of 30-day mortality (OR 0.313, 95% CI 0.114-0.853, p = 0.023) and unfaourable outcome at 12 months after TBI (OR 0.286, 95% CI 0.094-0.868, p = 0.027). Early surgery was associated with decreased 30-day mortality and better functional outcome at 12 months after TBI in older adults with few comorbidities and good functionality when clinically affected by acute traumatic intracranial lesions with mass effect.

Social Isolation and Mortality in Adults With Chronic Obstructive Pulmonary Disease

This cohort study uses national data to investigate the association between social isolation and all-cause mortality in adults with chronic obstructive pulmonary disease.

Association of dietary anthocyanidins intake with all-cause mortality and cardiovascular diseases mortality in USA adults: a prospective cohort study

Anthocyanins, as a type of polyphenolic compound, have been discovered to offer multiple health benefits to humans, including anti-aging and anti-inflammatory properties. This prospective cohort study aims to examine the relationship of dietary intake of anthocyanin with all-cause mortality and cardiovascular diseases mortality in the US. The aim of this research was to explore the possible correlation between anthocyanin consumption and the mortality rate from all causes as well as from cardiovascular disease. Based on the Public Access NHANES-linked National Death Index files up to December 31, 2019, we identified mortality status and heart disease-specific causes of death. A multivariate Cox regression analysis was employed to evaluate the effects of anthocyanin intake on mortality outcomes, generating hazard ratios and 95% confidence intervals, adjusting for various demographic characteristics, lifestyle factors, and comorbid conditions. Additionally, we utilized Kaplan-Meier survival curves, subgroup analyses. In different scenarios, dietary anthocyanin intake was assessed using restricted cubic spline models. A total of 11,959 participants completed the final cohort, averaging 47.12 years of age (SD ± 0.35). Following adjustments for multiple variables, an inverse relationship was identified between anthocyanin intake in the highest quartile and all causes mortality, yielding a hazard ratio (HR) of 0.68 (95% CI: 0.52–0.89). Similarly, elevated anthocyanin consumption was linked to a reduction in heart disease mortality, with HR of 0.61 (95% CI: 0.38–0.97). Additionally, dose–response curve revealed a consistent decrease in both all-cause and cardiovascular mortality with increasing anthocyanin intake. Further subgroup analyses revealed that elevated intake of anthocyanins was linked to decreased all-cause mortality in White individuals and males. Moreover, high anthocyanin intake was significantly correlated with reduced all-cause mortality irrespective of hypertension or hyperlipidemia status. Our research indicates that an appropriate dietary intake of anthocyanins is associated with a reduction in overall mortality rates. Furthermore, the findings reveal a substantial association between anthocyanin intake and decreased mortality from cardiovascular diseases, suggesting that anthocyanins may effectively lower the risk of cardiovascular-related deaths.

Motoric cognitive risk syndrome as a predictor of mortality in older male adults with cancer: A prospective cohort study in Peru

We aimed to assess motoric cognitive risk syndrome (MCRS) as a mortality predictor in older male adults with cancer at Centro Médico Naval (CEMENA) in Peru from 2012 to 2015. We conducted a secondary analysis of a prospective cohort within CEMENA's Geriatrics Service. We considered all-cause mortality as the primary outcome. MCRS was defined as slow gait speed, cognitive impairment, preserved activities of daily living, and absence of dementia. We utilized Poisson family generalized linear models with a logarithmic link function and robust variance to calculate both crude and adjusted relative risks (RR) with 95 % confidence intervals (95 % CI). We included 832 older male adults, with an MCRS frequency of 18.27 % (n = 152) and a mortality incidence of 22.84 % (n = 190). MCRS was a predictor of mortality in older adults at the end of follow-up (aRR=2.55; 95 % CI: 2.13–2.66). Survival was lower in older adults with MCRS (log-rank test p < 0.001). MCRS was a mortality predictor in older male adults with cancer.

Association of Psychotropic Prescriptions With Non-Registered Indications and the Risk of Mortality in Older Adults: A Danish Nationwide Cohort Study.

Psychotropic drug use is common in older adults, with off-label use reported despite limited understanding of the safety outcomes compared to on-label use. Incomplete recordings of treatment indications in the Danish National Prescription Register (DNPR) raise concerns about potential off-label medication use, particularly among older adults. We, therefore, investigated the association between psychotropic prescriptions with non-registered indications in DNPR and the 1-year all-cause mortality in older adults, including subgroups with any psychiatric disorders, depression, or dementia. Register-based cohort study following all older adults (≥ 65) who redeemed a first-time (since 1995) prescription of either antidepressants, antipsychotics, or benzodiazepine during 2006-2017. Redemption of a prescription with non-registered indications in the DNPR was the exposure. The outcome, 1-year all-cause mortality was analyzed using Poisson regression, estimating incidence rate ratios with 95% confidence intervals, adjusting for socio-demographics and clinical factors. 32% of prescriptions filled by 202,067 individuals for antidepressants, 37% of 97,387 for antipsychotics, and 22% of 130,471 for benzodiazepines had non-registered indications. No significant differences in mortality rates were found for antidepressants and antipsychotics with non-registered indications, while higher mortality rates were associated with benzodiazepines, mitigated when excluding individuals receiving intravenous administrations representing end-of-life treatment. The results remained consistent in subgroup analyses in patients with any psychiatric disorders, depression, or dementia and further stratified analyses by sex and age. We found that while psychotropic prescriptions with non-registered indications in DNPR were prevalent in older adults, they were not associated with excess mortality.

Obesity Paradox and the Effect of NT-proBNP on All-Cause and Cause-Specific Mortality.

In heart failure patients, obesity is associated with better outcomes as compared to normal weight, a phenomenon called the obesity paradox. To examine if obesity modifies the relationship between NT-proBNP and all-cause and cause-specific mortality in adults without coronary artery disease or heart failure history. We used the National Health and Nutrition Examination Survey (NHANES) data from 1999 to 2004 and linked it with mortality through December 31, 2019. Participants > 18 years were categorized into normal weight (BMI ≤ 25 kg/m2), overweight (BMI > 25-29.9 kg/m2) and obese (BMI > 29.9 kg/m2). NT-proBNP levels were categorized as low (< 126 pg/mL) or high (≥ 126 pg/mL). Using Cox proportional hazard models, we examined effect modification by obesity using interaction, without and with adjusting for potential confounders. Of the 12 621 participants, 2794 (22%) died during 202 859 person-years follow-up. In adjusted models, normal-weight participants with high NT-proBNP had 2 times higher all-cause mortality risk than those with low NT-proBNP (HR = 2.05; 95%CI = 1.74, 2.41; p < 0.001); however, this mortality risk was 27% lower in obese participants (HR interaction = 0.73; 95%CI = 0.59, 0.92; p = 0.008). Similarly, in normal-weight participants, the difference in other-cause mortality risk between high and low NT-proBNP participants was significant in adjusted models (HR = 2.27; 95%CI = 1.81, 2.85; p < 0.001) and obese participants had 48% lower other-cause mortality risk between those with high and low NT-proBNP (interaction HR = 0.52; 95%CI = 0.36, 0.77; p = 0.001). Conversely, obesity did not modify the relationship between NT-proBNP and cardiovascular or cancer mortality. In patients free of heart failure or coronary artery disease, obesity may be protective against mortality associated with high NT-proBNP.

A Comprehensive Review on the Significance of Cysteine in Various Metabolic Disorders; Particularly CVD, Diabetes, Renal Dysfunction, and Ischemic Stroke.

Metabolic disorders have long been a challenge for medical professionals and are a leading cause of mortality in adults. Diabetes, cardiovascular disorders (CVD), renal dysfunction, and ischemic stroke are the most prevalent ailments contributing to a high mortality rate worldwide. Reactive oxygen species are one of the leading factors that act as a fundamental root cause of metabolic syndrome. All of these disorders have their respective treatments, which, to some degree, sabotage the pathological worsening of the disease and an inevitable death. However, they pose a perilous health hazard to humankind. Cysteine, a functional amino acid shows promise for the prevention and treatment of metabolic disorders, such as CVD, Diabetes mellitus, renal dysfunction, and ischemic stroke. In this review, we explored whether cysteine can eradicate reactive oxygen species and subsequently prevent and treat these diseases.

A prospective mixed‐methods pilot study of a novel group structured education programme for adults with cystic fibrosis diabetes

AbstractBackground: Cystic fibrosis diabetes (CFD) is associated with increased morbidity and mortality in adults with cystic fibrosis (CF). In addition, poor glycaemic control can result in microvascular complications. Group educational programmes for people with type 1 and 2 diabetes have been shown to improve diabetes outcomes. The national guidelines recommend that people with CFD should receive education regarding diabetes; however, specific CFD group education programmes have not been evaluated.Aims: This study aimed to test whether this novel diabetes contents and intervention for CFD based on the Beta Cell Education Resources for Training in Insulin and Eating (BERTIE) type 1 diabetes education programme was beneficial for adults with CFD. The adapted course, Improved Diabetes Education in Adults with Cystic Fibrosis (IDEA‐CF ), incorporated CFD‐specific topics and was delivered virtually via videoconference group sessions to facilitate peer learning and support without the risk of cross‐infection. A pilot study was conducted utilising this novel IDEA‐CF virtual structured program to ensure that the intervention met the patients’ educational needs.Methods: This randomised controlled multimethods pilot study recruited adults with CFD taking insulin therapy and cared for by a large regional CF centre. After providing written informed consent, the participants completed all the study forms and questionnaires before randomisation. Randomisation was performed using a computerised randomisation system that allocated adults with CFD into the intervention group (IDEA‐CF) or routine care group for the 12‐week study period. Participants who were randomised into the routine group continued to receive one‐on‐one education as before. Using the CF quality‐of‐life (QoL) questionnaire (revised Cystic Fibrosis Questionnaire [CFQ‐R]), outcomes were measured at baseline and 12‐week visits in both groups. The participants in the intervention group were asked to take part in a semistructured qualitative interview after the completion of the intervention, which was performed by a CF psychologist.Results: A total of 20 participants were recruited, with 18 completing the intervention and study follow‐up visits. In the CFQ‐R domains, physical functioning, emotional functioning, eating, role functioning and respiratory symptoms were significantly improved in the intervention group compared with the routine care group. The IDEA‐CF Knowledge Assessing Questionnaire (IDEA‐CF KAQ) scores in the intervention group improved compared with the IDEA‐CF KAQ scores in the control group, suggesting that education improves knowledge and understanding. The IDEA‐CF structured virtual group education group was well received, with participants valuing the educational content and the ability to interact with each other and to learn from their peers’ experiences constructively.Conclusions: Our study demonstrated that the IDEA‐CF education programme improved health‐related QoL and diabetes knowledge, as evidenced by the results of the IDEA‐CF KAQ. The participants valued the educational contents of the programme and reported a positive experience interacting with their peers.

The Modified History of Juvenile Rheumatic Mitral Stenosis Following Percutaneous Transmitral Commissurotomy: Intermediate-Term Outcomes From a Decadal Follow-Up Study

There are few studies that have looked at the long-term outcomes of juvenile mitral stenosis (JMS) following percutaneous transmitral commissurotomy (PTMC). This study sought to analyse the modified history of JMS in children following PTMC. We describe a longitudinal, observational follow-up study of all children and young adults aged <20 years who underwent PTMC at Sri Jayadeva Institute of Cardiovascular Sciences and Research, Bangalore, India from 2012 to 2021. Children were followed up for progression of mitral stenosis (MS), development of mitral regurgitation (MR), need for repeat interventions (percutaneous or surgical), and mortality. A total of 114 children and adolescents underwent the procedure. The mean age of children in the study was 15.1±2.5 years. After immediate procedural success, there was a tendency towards restenosis with respect to valve areas and transmitral gradients at follow-up. Severe MR after the procedure was noted in 2.6%. Compliance with penicillin prophylaxis was noted in 42.5%. The Kaplan-Meier survival estimate over 10 years showed a mortality rate of 1.98/100 patient-years and a re-intervention rate (re-do PTMC or surgery) of 5.50/100 patient-years. Additional valvular lesions were noted in 13.1% of children during follow-up. Severe symptomatic status at presentation (New York Heart Association class 4) was predictive of mortality, and children aged <15 years often needed re-intervention. With a mortality rate of 6.1% and re-do intervention rate of 15.8% during extended follow-up, JMS has considerable healthcare implications in terms of morbidity and mortality in children and young adults.

An Overview on Disease Burden and Management of Respiratory Syncytial Virus Infections in Older Adults in the Asia-Pacific Region.

Respiratory syncytial virus (RSV) represents a significant burden on older adults (aged ≥ 50years) globally and can lead to acute respiratory tract infections with substantial morbidity and mortality. However, there is a significant gap in knowledge regarding RSV infection in older adults, particularly in the Asia-Pacific region. This knowledge gap underscores the need for targeted and comprehensive studies to fully understand the nuanced epidemiology of RSV in ageing populations. This review synthesises data from various countries, emphasising the impact of RSV on older populations in the Asia-Pacific region. The overall proportions of RSV-related ARIs among older patients ranged from 0.2% to 5.6%. Among older adult patients with CAP, RSV accounted for 1.1%-10.3% of cases. However, it is crucial to note that the diversity in reported percentages highlights the influence of factors such as geographic location, health care settings and diagnostic practices. The most common symptoms observed in older adults with RSV infection were cough, sputum production and fever, followed by dyspnoea, sore throat and rhinorrhoea. Most of the old adults with RSV infection had underlying diseases, and RSV can cause significant morbidity and mortality in old adults. Treatment of RSV infections predominantly involve supportive care, with aerosolised ribavirin reserved for severe cases, especially immunocompromised patients. Emerging antiviral agents, including fusion and nucleoprotein inhibitors, offer promising avenues for future therapeutics. The recent approval of the bivalent RSV prefusion F protein-based vaccine for individuals aged 60 and older represents a milestone in preventive strategies. In conclusion, RSV infection remains a significant threat to older adults in the Asia-Pacific region, necessitating ongoing research and surveillance efforts. The recent vaccine approval marks a positive milestone, but further studies are crucial for refining prevention and treatment approaches.

The contribution of cumulative blood pressure load to dementia, cognitive function and mortality in older adults.

Few studies evaluated the contribution of long-term elevated blood pressure (BP) towards dementia and deaths. We examined the association between cumulative BP (cBP) load and dementia, cognitive decline, all-cause and cardiovascular deaths in older Australians. We also explored whether seated versus standing BP were associated with these outcomes. The Sydney Memory and Aging Study included 1037 community-dwelling individuals aged 70-90 years, recruited from Sydney, Australia. Baseline data was collected in 2005-2007 and the cohort was followed for seven waves until 2021. cSBP load was calculated as the area under the curve (AUC) for SBP ≥140 mmHg divided by the AUC for all SBP values. Cumulative diastolic BP (cDBP) and pulse pressure (cPP) load were calculated using thresholds of 90 mmHg and 60 mmHg. Cox and mixed linear models were used to assess associations. Of 527 participants with both seated and standing BP data (47.7% men, median age 77), 152 (28.8%) developed dementia over a mean follow-up of 10.5 years. Higher cPP load was associated with a higher risk of all-cause deaths, and cSBP load was associated with a higher risk of cardiovascular deaths in multivariate models ( P for trend < 0.05). Associations between cPP load, dementia and cognitive decline lost statistical significance after adjustment for age. Differences between sitting and standing BP load were not associated with the outcomes. Long-term cPP load was associated with a higher risk of all-cause deaths and cSBP load associated with a higher risk of cardiovascular deaths in older Australians.

Mortality-related factors in older adults with delirium: A prospective observational study

BackgroundDelirium is a common and serious neuropsychiatric syndrome characterized by acute changes in attention, cognition, and consciousness. It is frequently encountered in various clinical settings, including critical care units and postoperative care, and is associated with significant morbidity and mortality. Understanding the factors contributing to delirium-related mortality is crucial for improving patient outcomes and healthcare practices. However, the factors associated with mortality in delirium have not been well-defined in the literature. ObjectivesThis study aimed to identify factors influencing 3-month mortality in older adults with delirium presenting to the emergency department (ED). MethodsThe study was conducted prospectively and delirium was screened using the brief Confusion Assesment Method (bCAM). The primary outcome was 3-month mortality. Mann-Whitney U and Chi-square tests compared groups, Spearman correlation analyzed correlations, and multivariate logistic regression identified risk factors. ResultsAmong 243 patients, 29.6% experienced in-hospital mortality, and 56.4% had 3-month mortality. Factors associated with increased mortality risk included prior delirium history (3.32-fold increase, 95%CI: 1.51-7.30), active malignancy (3.49-fold increase, 95%CI: 1.61-7.56) and increased respiratory rate (1.18-fold increase, 95%CI: 1.08-1.29). An increase in mean arterial pressure (MAP) was associated with a 0.98-fold decrease in mortality risk (95%CI: 0.96-0.99), increase in body temperature was associated with a 0.48-fold decrease in mortality risk (95%CI:0.31-0.76). ConclusionIn delirious older adults at the ED, higher respiratory rate, lower MAP, lower body temperature, active malignancy and prior delirium history signal elevated mortality risk.
