RESUMEN
This study assesses the impacts of the Science program at Piedmont Virginia Community College and its flagship capstone research experience, Supervised Study, through psychosocial perceptions associated with persistence in science and through a comparative analysis of subsequent science bachelor's degree attainment. Supervised Study involves authentic, independent projects, a research methods course and learning community, and one-on-one faculty mentoring. The Persistence in the Sciences survey was used as a repeated-measures instrument in four semesters of Supervised Study. Positive trends were observed for self-efficacy, science identity, community values, and networking, while responses related to project ownership were mixed (n = 13). To contextualize these observations, transfer and bachelor's degree completion rates were analyzed. Students who earn an associate's degree in Science (n = 113 between 2012 and 2019) complete bachelor's degrees at high rates (66.4%). Moreover, they are two to four times more likely to major in physical and natural sciences than their science-oriented peers, who take many of the same courses, with the exception of Supervised Study. Notably, these comparison rates remain consistent between different demographic groups. These findings further describe a model for research at the community college level that supports persistence in undergraduate science for a broad group of students.

BACKGROUND: The study determined whether the first procedure; simple drainage (tube thoracostomy, pigtail catheter) or operation (video-assisted thoracic surgery [VATS], thoracotomy) was related to outcomes in the management of empyema. METHODS: Data were collected from 104 consecutive patients with empyema. Primary outcomes were additional procedures and death. Predictor variables included age, delay, Karnofsky performance status (KPS), Charlson comorbidity index (CCI), serum albumin, malignancy, Acute Physiology and Chronic Health Evaluation II score, loculations on computed tomography scan, empyema stage, and first procedure choice. RESULTS: Advanced empyema (> or = stage IIA) was present in 84% of patients. Overall treatment success rates (no death, no additional drainage procedures) among evaluable patients for pigtail drainage, tube thoracostomy, VATS, and thoracotomy were 40% (4 of 10), 38% (14 of 37), 81% (13 of 16), and 89% (32 of 36), respectively. Five patients underwent miscellaneous procedures. Univariate variables associated with hospital death included KPS, CCI, and drainage as the first procedure. In multivariate analyses, KPS (coefficient, -0.06, p = 0.002) and failure of the first procedure (odds ratio [OR], 6.76; 95% confidence interval [CI], 1.45 to 31.4, p = .01) were independent predictors of death. Simple drainage as the first procedure was a strong, independent predictor of failure of the first procedure (OR, 11.1; 95% CI, 3.51 to 34.9; p = .00004). CONCLUSIONS: The choice of the first procedure is critical in the outcome for treatment of empyema, even with adjustment for confounding variables. VATS or thoracotomy as initial therapy for advanced empyema is associated with better outcomes.
