BACKGROUND: The association between ambient temperature and mortality has yielded inconclusive results with previous studies relying on in-patient data to assess the health effects of temperature. Therefore, we aimed to estimate the effect of ambient temperature on non-accidental mortality among elderly hypertensive patients through a prospective cohort study conducted in northeastern China.
METHODS: A total of 9634 elderly hypertensive patients from the Kailuan research who participated in the baseline survey and follow-up from January 1, 2006 to December 31, 2017, were included in the study. We employed a Poisson generalized linear regression model to estimate the effects of monthly ambient temperature and temperature variations on non-accidental mortality.
RESULTS: After adjusting for meteorological parameters, the monthly mean temperature (RR = 0.989, 95% CI: 0.984-0.993, p < 0.001), minimum temperature (RR = 0.987, 95% CI: 0.983-0.992, p < 0.001) and maximum temperature (RR = 0.989, 95% CI: 0.985-0.994, p < 0.001) exhibited a negative association with an increased risk of non-accidental mortality. The presence of higher monthly temperature variation was significantly associated with an elevated risk of mortality (RR = 1.097, 95% CI:1.051-1.146, p < 0.001). Further stratified analysis revealed that these associations were more pronounced during colder months as well as among male and older individuals.
CONCLUSIONS: Decreased temperature and greater variations in ambient temperature were observed to be linked with non-accidental mortality among elderly hypertensive patients, particularly notable within aging populations and males. These understanding regarding the effects of ambient temperature on mortality holds clinical significance for appropriate treatment strategies targeting these individuals while also serving as an indicator for heightened risk of death.

UNASSIGNED: Beyond our population growing older and living longer, there is an increased risk of developing a cognitive disorder. Standardized screening during a routine visit in primary care may be ideal for early detection of mild cognitive impairment (MCI) and follow-up for cognitive changes.
UNASSIGNED: This quality improvement (QI) project aimed to determine the impact of implementing the Mini-Cog© quick screening for early dementia detection to identify and follow up on the cognitive impairment of older adults in a primary care clinic setting.
UNASSIGNED: Implementation started in February 2024 in a primary care clinic in Southern California. Data was collected for this project over a total of 16 weeks. This QI project implemented a routine cognitive screening using the Mini-Cog©. Cognitive impairment was identified, and if indicated by the Mini-Cog© scores, follow-up for a cognitive assessment and care plan services were initiated. Data were obtained from the project site\'s electronic medical record on a total sample size of 471 participants (n = 382 in the pre-implementation group and n = 89 in the post-implementation group).
UNASSIGNED: Pearson\'s chi-square test indicated a statistically significant improvement in the identification rate of cognitive impairment, increasing from 11.8% (n = 45 out of 382) at pre-implementation to 34.8% (n = 31 out of 89) at post-implementation, and specifically, mild cognitive impairment increased from zero identified in pre-implementation to 12.4% (n = 11 out of 89) post-implementation. Lastly, follow-up rates improved from 91.1% (n = 41 out of 45) to 100% (n = 31 out of 31) in post-implementation, and clinical significance was evident based on the phi-coefficient (φ = 0.196), indicating a small effect size and a 100% follow-up rate.
UNASSIGNED: The findings of this project suggest older adults should receive cognitive screenings to help identify early cognitive impairment and increase follow-up for further evaluation, treatment, and advanced care planning.

OBJECTIVE: Peripheral neuropathies perturbate the sensorimotor system, causing difficulties in walking-related motor tasks and, eventually, falls. Falls result in functional dependency and reliance on healthcare, especially in older persons. We investigated if peripheral neuropathy is a genuine risk factor for falls in the elderly and if quantification of postural control via posturography is helpful in identifying subjects at risk of falls.
METHODS: Seventeen older persons with a clinical polyneuropathic syndrome of the lower limbs and converging electrophysiology were compared with 14 older persons without polyneuropathy. All participants were characterized via quantitative motor and sensory testing, neuropsychological assessment, and self-questionnaires. Video-nystagmography and caloric test excluded vestibulocochlear dysfunction. For further analysis, all subjects were stratified into fallers and non-fallers. Overall, 28 patients underwent computerized dynamic posturography for individual fall risk assessment. Regression analyses were performed to identify risk factors and predictive posturography parameters.
RESULTS: Neuropathy is an independent risk factor for falls in the elderly, while no differences were observed for age, gender, weight, frailty, DemTect test, timed \"Up & Go\" test, and dizziness-related handicap score. In computerized dynamic posturography, fallers stepped more often to regain postural control in challenging conditions, while the Rhythmic Weight Shift test showed a lack of anterior-posterior bidirectional voluntary control.
CONCLUSIONS: Our study confirms peripheral neuropathy as a risk factor for older persons\' falls. Fallers frequently used stepping to regain postural control. The voluntary control of this coping movement was impaired. Further investigations into these parameters\' value in predicting the risk of falls in the elderly are warranted.

BACKGROUND: Identifying priority challenges of older adults with chronic obstructive pulmonary disease (COPD) is critical to designing interventions aimed at improving their well-being and independence.
OBJECTIVE: To prioritize challenges of older adults with COPD and those who care for them to guide refinement of a telephonic nurse coach intervention for patients with COPD and their family caregivers (EPIC: Empowering People to Independence in COPD).
METHODS: Multiphase study guided by Baltes Theory of Successful Aging and the 5Ms Framework: Phase 1: Nominal group technique (NGT), a structured process of prioritizing responses to a question through group consensus. Phase 2: Rapid qualitative analysis. Phase 3: Intervention mapping and refinement.
METHODS: Ambulatory, virtual.
METHODS: Older adults with COPD, family caregivers, clinic staff (nurses, respiratory therapists), clinicians (physicians, nurse practitioners), and health system leaders.
RESULTS: NGT sessions were conducted by constituency group with 37 participants (n = 7 patients, n = 6 family caregivers, n = 8 clinic staff, n = 9 clinicians, n = 7 health system leaders) (Phase 1). Participants generated 92 statements across five themes (Phase 2): (1) \"Barriers to care\", (2) \"Family caregiver needs\", (3) \"Functional status and mobility issues\", (4) \"Illness understanding\", and (5) \"COPD care complexities\". Supplemental oxygen challenges emerged as a critical problem, and prioritized challenges differed by group. Patients and clinic staff prioritized \"Functional status and mobility issues\", family caregivers prioritized \"Family caregiver needs\", and clinicians and health system leaders prioritized \"COPD care complexities\". Intervention mapping (Phase 3) guided EPIC refinement focused on meeting patient priorities of independence and mobility but accounting for all priorities.
CONCLUSIONS: Diverse constituency groups identified priority challenges for older adults with COPD. Functional status and mobility issues, particularly related to supplemental oxygen, emerged as patient prioritized challenges.
CONCLUSIONS: Patient-centered interventions for older adults with COPD must account for their prioritized functional and supplemental oxygen needs and explore diverse constituent perspectives to facilitate intervention enrichment.

The clinical context of drug interactions detected by automated analysis systems is particularly important in older patients with multimorbidities. We aimed to provide unique, up-to-date data on the prevalence of potentially inappropriate medications (PIMs) and drug-drug interactions (DDIs) in the Polish geriatric population over 80 years old and determine the frequency and the most common PIMs involved in DDIs. We analyzed all non-prescription and prescription drugs in a representative national group of 178 home-dwelling adults over 80 years old with excessive polypharmacy (≥10 drugs). The FORTA List was used to assess PIMs, and the Lexicomp® Drug Interactions database was used for DDIs. DDIs were detected in 66.9% of the study group, whereas PIMs were detected in 94.4%. Verification of clinical indications for the use of substances involved in DDIs resulted in a reduction in the total number of DDIs by more than 1.5 times, as well as in a nearly 3-fold decrease in the number of interactions requiring therapy modification and drug combinations that should be strictly avoided. The most common PIMs involved in DDIs were painkillers, and drugs used in psychiatry and neurology. Special attention should be paid to DDIs with PIMs since they could increase their inappropriate character. The use of automated interaction analysis systems, while maintaining appropriate clinical criticism, can increase both chances for a good therapeutic effect and the safety of the elderly during treatment processes.

Monitoring the effectiveness of COVID-19 vaccination is critical for understanding if the vaccinated population, especially the elderly, is adequately protected from the emergence of new SARS-CoV-2 variants. This study aimed to investigate the effects of COVID-19 vaccination on the severity of symptoms and mortality in hospitalized geriatric patients during the Omicron BF.7 surge in Macao. Data from electronic health records and vaccination registry of inpatients aged 60 years or above admitted to Kiang Wu Hospital from 12 December 2022 to 12 March 2023 were retrospectively analyzed. The study involved 848 people, including 426 vaccinated and 422 unvaccinated individuals. The mean CXR scores (8.95 ± 9.49 vs. 11.41 ± 10.81, p < 0.001) and the mean MEWS scores (0.96 ± 2.01 vs. 1.49 ± 2.45, p < 0.001) were lower in the vaccinated group. By comparing the dose counts, no significant difference was seen in the odds of death. Based on the time of the last vaccination, 128 people were categorized as complete and 298 as incomplete vaccination. The complete vaccination group showed a 54% (95% CI 0.23-0.91) reduction in mortality risk (p = 0.026). The study findings not only reconfirm the effectiveness of COVID-19 vaccination but, more importantly, highlight the importance of vaccination timing to maximize vaccines\' protective effect.

Frailty is a complex condition that intensifies with age and is marked by decreased physiological function. We rigorously investigated the effects of lower vitamin intake on frailty using data from 665 adults aged over 65 years who consumed sufficient recommended daily energy and protein intakes from the Korean Nutrition and Health Survey, 2016-2019. The definition of frailty was modified based on Fried et al.\'s definition of weight loss, exhaustion, weakness, slowness, and low energy expenditure. Based on daily intake, we analyzed vitamins such as vitamin A, thiamine, riboflavin, niacin, folic acid, and vitamin C. Our results of logistic regression showed that increasing multiple deficiencies in several kinds of vitamins (mild to moderate to severe) is not associated with frailty (odds ratio: 1, 1.24 (0.24-3.10), 0.82 (0.28-2.39), p for trend = 0.626) in older adults who consumed sufficient calories and proteins. A subgroup analysis of age and sex, which may interfere with the relationship between vitamin intake and frailty, showed that vitamin intake was not associated with frailty when sufficient energy and proteins were consumed. Furthermore, there was no difference in the prevalence of frailty between the groups with sufficient and insufficient intakes of individual vitamins.

Background: Preserving health and physical fitness is critical to ensure independent living across the lifespan. Lower levels of physical fitness are associated with age-related cognitive decline and a higher prevalence of mild cognitive impairment (MCI). Thus, this study investigates the influence of a six-month dance intervention on selected measures of physical fitness in older adults with MCI. Methods: In this randomized controlled trial, 55 patients with MCI were randomized into a sportive dance training (IG; n = 26; age: 70.7 ± 5.6 years; 62% female) or an inactive control group (CG; n = 24; age: 69.1 ± 6.8 years; 46% female). The dance group received two 90 min dance training sessions per week over a duration of six-months, which focused on learning dance movement patterns. During the training sessions, heart rate was measured to control exercise intensity. Physical fitness was assessed using cardiopulmonary exercise testing (CPET), lower limb functional fitness via sit-to-stand test, handgrip strength, and heart rate variability (HRV). Results: We observed that the dance intervention preserved the cardiorespiratory fitness as measured by maximal oxygen uptake (VO2max) during CPET, which decreased in the CG. Furthermore, participants in the IG demonstrated increases in leg and handgrip strength, although these were not statistically significant. HRV displayed a non-significant decrease following the intervention. Conclusions: The results of this randomized controlled trial suggest that sportive dance training can preserve elements of physical fitness (i.e., cardiorespiratory fitness) in older adults with MCI. Although improvements in the other parameters (i.e., leg and handgrip strength) were statistically non-significant, likely due to the small sample size, stabilizing muscular fitness and preventing age-related decline in older adults with MCI is important for maintaining functional independence. For future studies, we recommend a longer training duration paired with precise control of regular physical activity levels, an important confounding factor.

BACKGROUND: Potentially inappropriate medications (PIMs) and polypharmacy constitute increasing healthcare costs and significant risk for adverse outcomes in older adults. The American Geriatrics Society Beers Criteria form a screening tool for the identification of PIMs and guidance for healthcare providers in prescribing appropriate medications. However, primary care physicians\' knowledge of screening tools, of Beers Criteria, in particular, is not known. Therefore, this study was to investigate primary care physicians in the Eastern Province of Saudi Arabia and their awareness of Beers Criteria and knowledge of PIMs.
METHODS: This cross-sectional study was conducted among primary care physicians working in the Eastern Province of Saudi Arabia. Data were collected using an online self-administered questionnaire that consisted of sections on the general characteristics of respondents and their knowledge of Beers Criteria as a screening tool. Eight clinical-based vignettes concerning different therapeutic areas of medication use in the elderly were included, with a score of 1 and 0 for correct and wrong answers, respectively. Data presented as frequency and percentage. Chi-square test was used to determine the association between duration of practice and the level of awareness about Beers criteria.
RESULTS: Of the 121 physicians who returned completed questionnaires, 41.3% of respondents knew about Beers Criteria. Most respondents (52.9%) were confident in prescribing appropriately for elderly patients. The association between the duration of practice and confidence level was statistically significant (P = 0.040). Respondents showed an above-average knowledge of the clinical vignettes with a correct answer rate >50% in all clinical scenarios. Online search (84.2%) and physician colleagues\' knowledge and experiences (39.2%) were the primary source of information reported by the respondents.
CONCLUSIONS: Awareness of Beers Criteria of primary care physicians in Saudi Arabia\'s Eastern Province is low. Therefore, our results will educate healthcare workers on the importance of Beers Criteria in Geriatric patients\' prescriptions, in order to significantly improve the well-being of the elderly.

UNASSIGNED: Poor sleep is associated with increased inflammation, thereby increasing the risk of chronic diseases and mortality. However, the effects of behavioral sleep interventions on the upstream inflammatory system are unknown among family care partners (CP). The present study explored the role of a behavioral sleep intervention program on inflammatory gene expression.
UNASSIGNED: This was part of a randomized controlled trial of a sleep intervention for dementia care dyads with sleep problems. Thirty dyads were randomized to sleep intervention or control groups. Sleep outcomes for CP were assessed with 1 week of actigraphy and sleep diary, and the Pittsburgh Sleep Quality Index. Other information included CP demographics, body mass index, and intensity of caregiving tasks. All outcomes were collected at baseline, post-treatment, and 3-month follow-up.
UNASSIGNED: Neither group showed any significant differential changes in gene expression from baseline to post-treatment or 3-month follow-up. A decrease in inflammatory gene expression was significantly associated with more nights of good sleep (i.e. nights without trouble falling or staying asleep at night). This finding remained significant after controlling for group (intervention/control), timepoint (baseline, post-treatment, and 3-month follow-up), and CP characteristics (e.g. age and ethnicity).
UNASSIGNED: Although better sleep was associated with decreased inflammatory gene expression, this study did not demonstrate any benefits of a behavioral sleep intervention over control, most likely due to a small sample. Studies with larger sample sizes are needed to test the specific aspects of disturbed sleep that relate to inflammatory biology among CP of persons living with dementia.
