We design and implement dynamic symmetric searchable encryption schemes that efficiently and privately search server-held encrypted databases with tens of billions of record-keyword pairs. Our basic theoretical construction supports single-keyword searches and offers asymptotically optimal server index size, fully parallel searching, and minimal leakage.(More)
OBJECTIVE At academic institutions, overnight emergency radiology examinations are interpreted by the on-call radiology resident and are reviewed by an attending radiologist in the morning. The objective of our study was to determine the rate of discrepancies between the two interpretations and the possible effect, if any, on patient care. MATERIALS AND(More)
PURPOSE Effective communication is central to patient safety. There is abundant evidence of negative consequences of poor communication and inadequate handoffs. The purpose of the current study was to conduct a systematic review of articles focused on physicians' handoffs, conduct a qualitative review of barriers and strategies, and identify features of(More)
Analysis of the body mass index of pediatric patients with gastrointestinal complaints as a whole and by disease subgroup revealed a greater percentage of obese patients with constipation, gastroesophageal reflux, irritable bowel syndrome, encopresis, and functional abdominal pain compared with local and New Jersey control populations.
PURPOSE Residents are being asked to participate in quality improvement (QI) initiatives in hospitals and clinics with increasing frequency; however, the effectiveness of improving patient care through residents' participation in QI initiatives is unknown. METHOD A thorough, systematic review of the English-language medical literature published between(More)
Warfarin induction is accomplished by titrating dosage to coagulation test results. Algorithms can guide this process but not identify the starting dose. We hypothesized that an initial warfarin dose approximating the maintenance value would safely enhance rapidity of induction. In a randomized trial we compared a fixed-dose to a maintenance-dose strategy(More)
We present new algorithm-substitution attacks (ASAs) on symmetric encryption that improve over prior ones in two ways. First, while prior attacks only broke a sub-class of randomized schemes having a property called coin injectivity, our attacks break ALL randomized schemes. Second, while prior attacks are stateful, ours are stateless, achieving a notion of(More)
OBJECTIVE Informal conversations and anecdotal evidence suggest that the job turnover rate among radiology residency program directors is disproportionately high. The purpose of our study was to assess the characteristics of current program directors and determine factors that may be affecting overall job satisfaction and job turnover rate. SUBJECTS AND(More)
BACKGROUND There is limited information concerning the risks for, and occurrence of, cardiovascular complications because of GI endoscopy. Published data are based on questionnaire surveys, which have a potential for bias. Moreover, available studies pertain exclusively to out-patients. METHODS In-patients and day-stay patients who incurred charges for(More)
OBJECTIVE To test the reliability of the 360-degree evaluation instrument for assessing residents' competency in interpersonal and communication skills. METHOD Ten-item questionnaires were distributed to residents and evaluators at Monmouth Medical Center in Long Branch, New Jersey, in March/April, 2002. The scoring scale was 1-5; the highest score was(More)
