Background: The association between sodium-glucose cotransporter-2 inhibitors (SGLT2i) use and cognitive function in type 2 diabetes remains unclear. Objective: Explore the association between SGLT2i and longitudinal changes in cognitive function in adults with type 2 diabetes (T2DM) and assessed the cognitive domains which were impacted by SGLT2i. Methods: We conducted a prospective cohort study of 476 patients aged 60.6±7.4 years with follow-up period up to 6.4 years. Data on SGLT2i use was derived from questionnaire and verified with clinical database. We used Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) to assess cognition. The association between SGLT2i use and rate of RBANS score change was examined using multiple linear regression. Results: There were 138 patients (29.0%) on SGLT2i, including 84 (17.7%) for

Fluid imbalance is associated with various clinical conditions, but the association between elevated extracellular-water to total-body-water (ECW/TBW) ratio, an indicator of fluid balance, and cognitive impairment is unknown. We aimed to investigate relationship between ECW/TBW ratio and cognitive function in type 2 diabetes mellitus.This study was a cross-sectional design, comparing 1233 patients aged 61.4 ± 8.0 years from the Singapore Study of Macro-angiopathy and Micro-vascular Reactivity in Type 2 Diabetes (SMART2D) cohort. ECW/TBW was measured using bioelectrical impedance method. Cognitive function was assessed with Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Multiple linear regression was used to examine association between ECW/TBW and RBANS scores, adjusting for demographics, education, clinical covariates, and apolipoprotein E allele.In unadjusted analyses, there was an inverse dose-dependent association between ECW/TBW and RBANS total score. The associations persisted in fully adjusted model with β = -1.18 (95% confidence interval [CI] -2.19 to -0.17; P = 0.022) for slight edema and -2.33 (-3.99 to -0.67; P = 0.006) for edema. Slight edema and edema were significantly associated with reduced cognitive function in delayed memory and attention. There was significant association between edema but not slight edema, with reduced cognitive function in language. Pulse pressure accounted for 16.8% of association between ECW/TBW and RBANS total score.Our novel finding of an independent association between higher ECW/TBW and poorer cognitive function highlights the potential importance of maintaining body fluid balance in the management of cognitive impairment.背景: 体液失衡与多种临床症状有关, 但作为体液平衡指标的细胞外液/全身水比值(ECW/TBW)升高与认知功能损害之间的关系尚不清楚。本研究旨在探讨2型糖尿病患者ECW/TBW比值与认知功能的关系。 方法: 本研究采用横断面设计, 比较了新加坡2型糖尿病大血管病变和微血管反应性研究(SMART2D)队列的1233例患者, 年龄在61.4±8.0岁。采用生物电阻抗法测量ECW/TBW。认知功能采用可重复使用的神经心理状态评定量表(RBANS)进行评定。在校正了人口统计学、教育程度、临床协变量和载脂蛋白E等位基因后, 采用多元线性回归来检验ECW/TBW和RBANS评分之间的相关性。 结果: 在非校正分析中, ECW/TBW与RBANS总分呈剂量负相关。这种关联持续存在于完全校正轻度水肿β=− 1.18(95% 置信区间 [CI] −2.19 to −0.17; P = 0.022)和水肿β= −2.33 (−3.99 to −0.67; P = 0.006) 的模型中。轻度水肿和水肿与延迟记忆和注意力的认知功能降低显著相关。语言认知功能下降与水肿之间有显著的相关性。脉搏压可解释ECW/TBW与RBANS总分相关性的16.8%。 结论: 我们首次发现较高的ECW/TBW和较差的认知功能之间存在独立的关联, 这突出了在认知障碍的管理中保持体液平衡的潜在重要性。.

We aim to examine body composition, and association between SO and cognitive performance in Type 2 Diabetes (T2D) in an Asian population in Singapore.This was a cross-sectional study on 1235 patients with mean age 61.4 ± 8.0 years and T2D primary and secondary care attending diabetes care in Singapore. Body composition was assessed using tetrapolar multi-frequency BIA device analysis. Fat mass to fat-free mass (FM/FFM) ratio was categorized into 3 groups: Group 1, normal,0.40; Group 2, obese and increase of FM is small relative to that in FFM, 0.40 to 0.80; and Group 3, SO,0.80. Cognition was assessed using Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) and Mini-Mental State Examination (MMSE).The distribution of body composition based on FM/FFM ratio was: Group 1, 20.2%; Group 2, 60.5%; and Group 3, 19.4%. SO (Group 3) was significantly associated with reduced RBANS total score with β-1.44 (95%CI -2.82 to -0.06; p = 0.041) in multivariable linear regression adjusted for demographics, education, depressive symptom(s) and clinical covariates. SO was significantly associated with reduced index scores for immediate memory and language in fully adjusted models with corresponding βs -2.71 (95%CI -5.06 to -0.36; p = 0.024) and -2.48 (95%CI -4.87 to -0.08; p = 0.043). Association between SO and reduced MMSE score was similarly observed.The prevalence of SO in Asians with T2D is relatively high. There is consistent and independent association of SO with reduced cognitive performance, especially in domains of memory and language, which may impair complex executive function such as adherence to diabetes self-care management.

Our aim was to study the prevalence of frailty and its associated factors in a subacute geriatric ward.This was a cross-sectional study of 167 participants between June 2018 and June 2019. Baseline demographics and participants' Mini Nutritional Assessment, Geriatric Depression Scale, Mini Mental State Examination, Charlson's Comorbidity Index and LACE index scores were obtained. Functional measurements such as modified Barthel's Index scores and hand grip strength (HGS) were taken. Frailty was assessed using the Clinical Frailty Scale (CFS) and the FRAIL scale. Data on history of healthcare utilisation, medications, length of stay, selected blood investigations and presence of geriatric syndromes was also collected.The prevalence of pre-frailty (CFS 4) and frailty (CFS ≥ 5) was 16.2% and 63.4%, respectively. There were significant associations between CFS and age (pre-frail vs. non-frail: odds ratio [OR] 1.14, 95% confidence interval [CI] 1.04-1.25, p = 0.006; frail vs. non-frail: OR 1.08, 95% CI 1.01-1.15, p = 0.021), HGS at discharge (frail vs. non-frail: OR 0.90, 95% CI 0.82-0.99, p = 0.025), serum albumin (frail vs. non-frail: OR 0.90, 95% CI 0.82-0.99, p = 0.035) and the presence of urinary incontinence (frail vs. non-frail: OR 3.03, 95% CI 1.19-7.77, p = 0.021).Frailty is highly prevalent in the subacute geriatric setting and has many associated factors. In this study, independent factors associated with frailty were age, HGS at discharge, serum albumin and urinary incontinence. This has implications for future resource allocation for frail older inpatients and may help direct further research to study the effectiveness of frailty-targeted interventions.

Introduction Fear of Falling (FoF) is common after hip fracture and associated with adverse outcomes including impaired functional recovery and recurrent falls. The objective of this study was to measure self-efficacy related to falls and its association with functional outcomes after hip fracture surgery. Methods A prospective cohort study was performed on 106 community-dwelling elderly aged ≥65 years without dementia, admitted to a community hospital for rehabilitation after surgery for fragility hip fracture in Singapore. They were managed in an integrated multidisciplinary orthogeriatric programme, transitioning from acute orthopaedic unit to the affiliated community hospital. Falls Efficacy Scale (FES; range 10-100) was assessed on discharge. Main outcomes measured included Parker Mobility Score (PMS) and Modified Barthel Index (MBI) at 3 months. Results Key characteristics of the cohort were: mean age 79.4(SD 6.38); female 74%, Chinese 83%, pre-fracture PMS 6.7(SD 2.7); pre-fracture MBI 81.1(SD 20.9); mean FES score 32.0(SD 23.7). At 3 months, mean PMS was 3.97(SD 2.51); mean MBI was 73(SD 20.1), demonstrating that the cohort overall did not regain their pre-morbid functional levels. FES was negatively correlated with both 3-month MBI and PMS with coefficients -0.592 and -0.523 respectively (p Conclusion FoF is a potentially modifiable factor linked to adverse functional outcomes in hip fracture rehabilitation, indicating the necessity to address falls self-efficacy as a major component of assessment and intervention, whilst further exploring the local validity and applicability of various instruments measuring FoF. Further studies need to be conducted on the evolving patterns of FoF over time and its impact on longer-term functional and psychosocial outcomes.

To examine the longitudinal association between skeletal muscle mass (SMM) loss and cognitive decline over time in type 2 diabetes mellitus (T2DM).We conducted a prospective cohort study of 453 patients from SMART2D cohort with follow-up intervals of 1.6 to 6.4 years. Baseline and follow-up measurements included bio-impedance analysis (BIA) measure of skeletal muscle mass index (SMI) and Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) measure of cognitive function. We examined the association between annual rate of SMI and RBANS scores using linear regression, adjusting for demographics, education, depression, clinical co-variables and presence of apolipoprotein E4 (APOE)The mean age of participants was 60.3 ± 7.4 years. Compared to patients with Tertile 1 SMI change, the group with greater SMI decline (Tertile 3 SMI change) experienced 0.30 decline in RBANS total score (95%CI -0.57 to -0.03; p = 0.030) in the adjusted analysis. RBANS scores for subdomains in immediate memory and visuo-spatial/construction were lower in Tertile 3 SMI change group with corresponding coefficients -0.54 (95%CI -1.01 to -0.06; p = 0.026), and -0.71 (95%CI -1.30 to -0.12; p = 0.019) respectively.In patients with T2DM, BIA measure of muscle mass loss over time was independently associated with cognitive decline globally and in the domains of memory and visuo-spatial/construction.

Lower extremity skeletal muscle mass (LESM) in Type 2 Diabetes (T2D) has been linked to adverse clinical events, but it is not known whether it is associated with cognitive difficulties. We conducted a cross-sectional study on 1,235 people (mean age 61.4 ± 8.0 years) with T2D under primary and secondary care in Singapore. Bioelectrical impedance analyses (BIA) measures of upper extremity skeletal muscle mass (UESM), LESM and appendicular skeletal muscle index (SMI) were related to the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) measures of cognition, in multiple linear regression. In multivariable models, tertile 1 LESM (b = −2.62 (−3.92 to −1.32)) and tertile 2 LESM (b = −1.73 (−2.73 to −0.73)), referenced to tertile 3) were significantly associated with decreased RBANS total score. Significant associations of LESM with cognitive domain performances were observed for tertile 1 (b = −3.75 (−5.98 to −1.52)) and tertile 2 (b = −1.98 (−3.69 to −0.27)) with immediate memory, and for tertile 1 (b = −3.05 (−4.86 to −1.24)) and tertile 2 (b = −1.87 (−3.25 to −0.48)) with delayed memory, and for tertile 1 (b = −2.99 (−5.30 to −0.68)) with visuospatial/constructional ability. Tertile 1 SMI (b = −1.94 (−3.79 to −0.08) and tertile 2 SMI (b = −1.75 (−3.14 to −0.37)) were also associated with delayed memory. There were no associations between UESM with cognitive performance. Lower LESM may be a useful marker of possible co-occuring cognitive dysfunction.

Background To test a population health program which could, through the application of process redesign, implement multiple evidence-based practices across the continuum of care in a functionally integrated health delivery system and deliver highly reliable and consistent evidence-based surgical care for patients with fragility hip fractures in an acute tertiary general hospital. Methods The ValuedCare (VC) program was developed in three distinct phases as an ongoing collaboration between the Geisinger Health System (GHS), USA, and Changi General Hospital (CGH), Singapore, modelled after the GHS ProvenCare® Fragile Hip Fracture Program. Clinical outcome data on consecutive hip fracture patients seen in 12 months pre-intervention were then compared with the post-intervention group. Both pre- and post-intervention groups were followed up across the continuum of care for a period of 12 months. Results VC patients showed significant improvement in median time to surgery (97 to 50.5 h), as well as proportion of patients operated within 48 h from hospital admission (48% from 18.8%) as compared to baseline pre-intervention data. These patients also had significant reduction (p value

To examine correlation between vascular measures and cognitive performance in type 2 diabetes (T2D).This was a cross-sectional study on patients (N = 1167) aged ≥45 years attending Diabetes Centre in a tertiary hospital and primary care polyclinic. The following vascular measures were measured: systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), pulse pressure (PP), pulse wave velocity (PWV) and augmentation index (AI). Cognition was assessed by Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Multiple linear regression was used to examine relationships between vascular measures and cognition, adjusting for demographics, education, depression, clinical covariates and presence of APOEIn unadjusted analyses, all the vascular measures, except for MAP, were associated with RBANS total score. In fully adjusted analyses, the association with RBANS total score persisted for peripheral PP, aortic PP and aortic DBP with βs -0.05 (95%CI -0.07 to -0.02; p = 0.001), -0.04 (95%CI -0.06 to -0.01; p = 0.002) and 0.05 (95%CI 0.00 to 0.09; p = 0.033). Association between peripheral and aortic PP and RBANS total score was unaffected by age-stratification (age60 and ≥60 years). In contrast, significant association between aortic DBP and RBANS total score was only observed for those ≥60 years. Peripheral and aortic PP (which estimate pulsatility) are negatively associated with attention, visuospatial/constructional and language ability.Peripheral and aortic PP, and aortic DBP were independently correlated with cognitive performance globally and in multiple domains. Further research should be conducted to establish the clinical relevance and importance.

Aim: Admission to an acute care geriatric unit may lead to adverse outcomes. It is therefore important to identify high-risk patients early so that appropriate management can be instituted to prevent or delay onset of adverse events. The aim of this study is to evaluate one-year mortality and its associated risk factors among hospitalized patients. Methods: This is a retrospective cohort study on consecutive patients admitted to an acute geriatric ward in a Singapore hospital from March to April 2013.Demographic and clinical information was collected from patient medical records. Linkage with death records from a national registry was performed. Results: Of the 196 patients assessed, 4.6%, 20.9% and 35.7% died during admission, within six months post-admission and within one year post-admission respectively. Pneumonia and cardiovascular diseases accounted for most of the death cases. In the multivariable logistic regression adjusted by age and gender, abbreviated mental test (AMT) score, admission for falls and depression were found to be significantly associated with death within one year post-admission. In the analysis stratified by gender, AMT score and depression were found to be significantly associated with death in males whereas AMT score and admission for falls were significantly associated with death in females. Conclusions: This study offers significant insight into mortality trends and risk factors for clinicians, hence guiding them in individualizing their management plan for acutely ill geriatric patients. Predicting long-term prognosis will enhance rehabilitation goal-setting and advance care-planning.

Falls among the elderly is a major public health concern. There has been recent extensive research on the effects of Tai Chi in fall prevention among the elderly. As such, we undertook a systematic review to look for evidence on the effect of this intervention. There were seven randomized controlled trials, which met our objective and inclusion criteria. Our review has shown that Tai Chi has the potential to reduce falls or risk of falls among the elderly, provided that they are relatively young and non-frail. Further review is needed to look into the non-English studies, which assess the effectiveness of Tai Chi on fall reduction.
