Abstract
BACKGROUND To determine the prevalence, risk factors; and impact on patient health and economic outcomes across the laterality spectrum of multiple sensory impairment (MSI) in a multi-ethnic older Asian population. METHODS In this population-based study of Singaporeans aged ≥ 60 years, MSI was defined as concomitant vision (visual acuity > 0.3 logMAR), hearing (pure-tone air conduction average > 25 dB), and olfactory (score < 12 on the Sniffin' Sticks test) impairments across the spectrum of laterality (any, unilateral, combination [of unilateral and bilateral], and bilateral). RESULTS Among 2,057 participants (mean ± SD 72.2 ± 0.2 years; 53.1% female), the national census-adjusted prevalence rates of any, unilateral, combination, and bilateral MSI were 20.6%, 1.2%, 12.2%, and 7.2%, respectively. Older age, male gender, low socioeconomic status (SES), and smoking (all p < 0.05) were independently associated with higher likelihood of any MSI. Compared to those with no sensory loss, those with MSI had significantly decreased mobility (range 5.4%-9.2%), had poor functioning (OR range 3.25-3.45) and increased healthcare costs (range 4-6 folds) across the laterality spectrum. Additionally, bilateral MSI had a significant decrease in HRQoL (5.5%, p = 0.012). CONCLUSIONS MSI is a highly prevalent medical condition, with 1 in 5; and almost 1 in 10 community-dwelling older Asians having any and bilateral MSI, respectively, with a higher likelihood in men, smokers, and those with low SES. Critically, MSI has a substantial negative impact on patient health and economic outcomes across the laterality spectrum. Sensory testing is critical to detect and refer individuals with MSI for management to improve their functional independence and QoL.

Abstract
INTRODUCTION Although living alone is associated with social disconnection, older adults could be socially disconnected despite living with others. Understanding the factors associated with social disconnection by living arrangement could help identify vulnerable older adults in the community. We examined the sociodemographic and health factors associated with social disconnection among two groups of older adults: those living alone and those living with others. METHODS We used data from 16,943 community-dwelling older adults from the third follow-up of the Singapore Chinese Health Study (mean age: 73 years, range: 61-96 years). We defined social disconnection as having no social participation and scoring in the lowest decile on the Duke Social Support Scale of perceived social support. We ran logistic regression models to study the sociodemographic (age, gender, and education) and health (self-rated health, instrumental limitations, cognitive function, and depression) factors associated with social disconnection, stratified by living arrangement. RESULTS About 6% of our participants were socially disconnected. Although living alone was significantly associated with social disconnection (OR 1.93, 95% CI: 1.58-2.35), 85.6% of socially disconnected older adults lived with others, most of them (92%) with family. Lower education level, cognitive impairment, fair/poor self-rated health, instrumental limitations, and depression were independently associated with social disconnection. Among those living alone, men were more likely to experience social disconnection than women (OR 2.18, 95% CI: 1.43-3.32). DISCUSSION/CONCLUSION Though living alone is associated with social disconnection, most socially disconnected individuals lived with family. Community interventions could focus on those in poor health despite living with family and older men living alone.

Abstract
BACKGROUND Essential tremor (ET) is among the most prevalent neurological diseases. Its environmental determinants are poorly understood. Harmane (1-methyl-9H-pyrido[3, 4-b]indole), a dietary tremor-producing neurotoxin, has been linked to ET in a few studies in New York and Madrid. Mercury, also a tremor-producing neurotoxin, has not been studied in ET. The Faroe Islands have been the focus of epidemiological investigations of numerous neurological disorders. OBJECTIVE In this population-based, case-control study, we directly measured blood harmane concentrations (HA) and blood mercury concentrations (Hg) in ET cases and controls. METHODS In total, 1,328 Faroese adults were screened; 26 ET cases were identified whose (HA) and (Hg) were compared to 197 controls. RESULTS Although there were no statistically significant differences between diagnostic groups, median (HA) was 2.7× higher in definite ET (4.13 g-10/mL) and 1.5× higher in probable ET (2.28 g-10/mL) than controls (1.53 g-10/mL). Small sample size was a limitation. For definite ET versus controls, p = 0.126. (Hg) were similar between groups. CONCLUSIONS We demonstrated marginally elevated (HA) in definite and probable ET. These data are similar to those previously published and possibly extend etiological links between this neurotoxin and ET to a third locale. The study did not support a link between mercury and ET.

Abstract
OBJECTIVE/BACKGROUND The understanding of abdominal compartment syndrome (ACS), and its importance for outcome, has increased over time. The aim was to investigate the incidence and clinical consequences of ACS after open (OR) and endovascular repair (EVAR) for ruptured and intact infrarenal abdominal aortic aneurysm (rAAA and iAAA, respectively). METHODS In 2008, ACS and decompression laparotomy (DL) were introduced as variables in the Swedish vascular registry (Swedvasc), offering an opportunity to study this complication in a prospective, population based design. Operations carried out in the period 2008-13 were analysed. Of 6,612 operations, 1,341 (20.3%) were for rAAA (72.0% OR) and 5,271 (79.7%) for iAAA (41.9% OR). In all, 3,171 (48.0%) were operated on by OR and 3,441 by EVAR. Prophylactic open abdomen (OA) treatment was validated through case records. Cross-matching with the national population registry secured valid mortality data. RESULTS After rAAA repair, ACS developed in 6.8% after OR versus 6.9% after EVAR (p = 1.0). All major complications were more common after ACS (p < .001). Prophylactic OA was performed in 10.7% of patients after OR. For ACS, DL was performed in 77.3% after OR and 84.6% after EVAR (p = .433). The 30 day mortality rate was 42.4% with ACS and 23.5% without ACS (p < .001); at 1 year it was 50.7% versus 31.8% (p < .001). After iAAA repair, ACS developed in 1.6% of patients after OR versus 0.5% after EVAR (p < .001). Among those with ACS, DL was performed in 68.6% after OR and in 25.0% after EVAR (p = .006). Thirty day mortality was 11.5% with ACS versus 1.8% without it (p < .001); at 1 year it was 27.5% versus 6.3% (p < .001). When ACS developed, renal failure, multiple organ failure, intestinal ischaemia, and prolonged intensive care were much more frequent (p < .001). Morbidity and mortality were similar, regardless of primary surgical technique (OR/EVAR/iAAA/rAAA). CONCLUSION ACS and OA were common after treatment for rAAA. ACS is a devastating complication after surgery for rAAA and iAAA, irrespective of operative technique, emphasizing the importance of prevention.
