About

Dr. Eric Tien Yen Chyn is an Associate Professor in the Department of Medicine and the Director of the Geriatric Medicine Fellowship Program at Rutgers Health New Jersey Medical School. He earned his Bachelor of Science in 2009 from the University of British Columbia and his Doctor of Medicine in 2013 from St. George's University in Grenada, West Indies. He completed his Internal Medicine Residency in 2016 at Icahn School of Medicine at Mount Sinai, Queens Hospital Center Program, and his Geriatric Fellowship in 2017 at Mount Sinai Hospital. Since joining the faculty at New Jersey Medical School in 2020, Dr. Chyn has initiated the first geriatric care and consultation clinic within the Ambulatory Care Center and established the first inpatient geriatrics consultation service within the University Hospital System. His research includes topics such as mobility improvement and rehospitalization risk following discharge from skilled nursing facilities, as well as the prevalence and outcomes of dysphagia in the geriatric population.

  Background Aspiration pneumonia is common in older adults admitted for community-acquired pneumonia and is associated with significant morbidity and mortality. Factors that put this population at higher risk of aspiration include cognitive impairment, neuromuscular dysfunction, and dysphagia. This study aimed to determine whether a concurrent diagnosis of dysphagia conferred a higher risk of complications in the elderly admitted for aspiration pneumonia. Methods The National Inpatient Sample 2001-2013 database was queried for patients, aged 65 or older, with a diagnosis of aspiration pneumonia using International Classification of Diseases, Ninth Revision (ICD-9) codes. Sepsis, respiratory failure, and intubation were identified with their respective ICD-9 codes. A chi-square test and binary logistic regression analysis were used to examine socio-demographic and complication variables, with a significance level of α <0.001. Results A total of 1,097,325 patients were admitted for aspiration pneumonia, of which 349,861 (24.2%) had dysphagia. After incorporating socio-demographic variables, the dysphagia group had a significantly lower likelihood of having sepsis (OR=0.72), respiratory failure (OR=0.92), intubation (OR=0.52), and inpatient mortality (OR = 0.59). Patients with dysphagia had a significantly higher likelihood of increased length of stay (OR=1.24). Conclusions Elderly patients admitted with aspiration pneumonia with a co-diagnosis of dysphagia were less likely to have inpatient morbidity and mortality compared to their counterparts. This may be due to improved speech evaluation and treatment in patients with dysphagia allowing for better control of macro and micro aspiration. Future research is needed to examine if universal speech therapy can reduce hospitalization and long-term mortality for such patients.

• Neighborhoods Matter: Assessing the Evidence for Place Effects

  How does one's place of residence affect individual behavior and long-run outcomes? Understanding neighborhood and place effects has been a leading question for social scientists during the past half-century. Recent empirical studies using experimental and quasi-experimental research designs have generated new insights on the importance of residential neighborhoods in childhood and adulthood. This paper summarizes the recent neighborhood effects literature and interprets the findings. Childhood neighborhoods affect long-run economic and educational outcomes in a manner consistent with exposure models of neighborhood effects. For adults, neighborhood environments matter for their health and well-being but have more ambiguous impacts on labor market outcomes. We discuss the evidence on the mechanisms behind the observed patterns and conclude by highlighting directions for future research.
