Survey of developmental milestones in internal medicine among residents and faculty.

OBJECTIVES: The published Accreditation Council for Graduate Medical Education (ACGME) milestones represent a novel method of evaluation of trainees in graduate medical education. We surveyed agroup of teaching faculty and residents, regarding the new ACGME milestones project. We obtained their input on the expected timeline for the developmental milestones and compared their responses to the ACGME recommendations. METHODS: A 42-item survey questionnaire, derived from the original 142 item publication, was completed by 26 internal medicine teaching faculty and 34 internal medicine residents. RESULTS: We found statistically significant differences in the responses given by residents and faculty compared to those in the standard recommendations. The differences were more pronounced with the residents than with the faculty. CONCLUSIONS: The results of our survey showed significantly different responses as compared to the standard recommended timelines. Since this is a novel evaluation process, substantial faculty development and resident education regarding the process can help improve its implementation. Future studies should focus on how learners might better understand and refine the milestone evaluation process.

Monolayer Twisted Graphene-Based Schottky Transistor.

The outstanding properties of graphene-based components, such as twisted graphene, motivates nanoelectronic researchers to focus on their applications in device technology. Twisted graphene as a new class of graphene structures is investigated in the platform of transistor application in this research study. Therefore, its geometry effect on Schottky transistor operation is analyzed and the relationship between the diameter of twist and number of twists are explored. A metal-semiconductor-metal twisted graphene-based junction as a Schottky transistor is considered. By employing the dispersion relation and quantum tunneling the variation of transistor performance under channel length, the diameter of twisted graphene, and the number of twists deviation are studied. The results show that twisted graphene with a smaller diameter affects the efficiency of twisted graphene-based Schottky transistors. Additionally, as another main characteristic, the ID-VGS is explored, which indicates that the threshold voltage is increased by diameter and number of twists in this type of transistor.

Experiences with a combined residency in internal and preventive medicine.

BACKGROUND: The importance of integrating preventive medicine training into other residency programs was reinforced recently by the residency review committee for preventive medicine. Griffin Hospital in Derby CT has offered a 4-year integrated internal medicine and preventive medicine residency program since 1997. This article reports the outcomes of that program. METHODS: Data were collected from surveys of program graduates and the American Boards of Internal and Preventive Medicine in 2005-2007, and analyzed in 2007-2008. Graduates rated the program in regard to job preparation, the ease of transition to employment, the value of skills learned, the perceived quality of board preparation, and the quality of the program overall. Graduates rated themselves on core competencies set by the Accreditation Committee for Graduate Medical Education. RESULTS: Since 1997, the program has enrolled 22 residents. Residents and graduates contribute significantly toward quality of care at the hospital. Graduates take and pass at high rates the boards for both for internal and preventive medicine: 100% took internal medicine boards, 90% of them passed; 63% took preventive medicine boards, 100% of them passed). The program has recruited residents mainly through the match. Graduates rated most elements of the program highly. They felt well-prepared for their postgraduation jobs; most respondents reported routinely using preventive medicine skills learned during residency. Graduates either have gone into academic medicine (31%); public health (14%); clinical fellowships (18%); or primary care (9%); or they combine elements of clinical medicine and public health (28%). CONCLUSIONS: Integrating preventive medicine training into clinical residency programs may be an efficient, viable, and cost-effective way of creating more medical specialists with population-medicine skills.

Tick-borne disease preventive practices and perceptions in an endemic area.

Lyme disease is the most commonly reported vector-borne illness in the United States. Since the institution of Nationally Notifiable surveillance efforts for Lyme disease in the United States in 1991, there has been a consistent increase in the number of reported cases. Thus, the need for targeted prevention strategies is underscored. The purpose of this study was to investigate knowledge about tick-borne diseases as well as beliefs and practices related to a variety of personal tick-borne disease prevention methods among individuals in southwestern Connecticut, a Lyme disease-endemic area. Between June and September 2014, an anonymous questionnaire was administered to 275 participants through a point-of-contact convenience sample obtained at community events in southwestern Connecticut. The questionnaire assessed individuals' general knowledge about tick-borne diseases, performance of four selected tick-borne disease prevention methods, and perceived effectiveness and burdensomeness of those four behaviors. Some 80% of participants were female; median age was 55 years (IQR 45-64 years); 30% reported having been treated for a tick-borne illness and 50% reported a family member having been treated for a tick-borne illness. Overall, participants' knowledge of tick-borne diseases was poor; the average knowledge score was only 57% (SD 22.6%). The reported frequency of performing preventive behaviors was variable. The most commonly reported behavior was performing a tick check (68%); use of tick repellent was the least commonly reported behavior (38%). Those who were more knowledgeable about Lyme disease were more likely to perform tick checks but knowledge score was not significantly associated with any of the other three behaviors studied. Respondents largely believed preventive behaviors to be effective at reducing the risk of tick-borne diseases. Belief that a prevention behavior is effective was highly correlated with performing that behavior but perceived burdensomeness does not appear to influence behavior performance. The reasons for differential uptake of preventive behaviors remains unknown; further study of barriers to performance of personal preventive behaviors is needed to better target public health interventions.

Utility of HbA(1c) levels for diabetes case finding in hospitalized patients with hyperglycemia.

OBJECTIVE: We evaluated the role of a single measurement of HbA(1c) in a diabetes case finding in hospitalized patients with random hyperglycemia at admission. RESEARCH DESIGN AND METHODS: From 20 March to 31 July 2000, 508 patients admitted through the emergency department of one hospital were tested for random hyperglycemia (plasma glucose [PG] >125 mg/dl). Consenting patients with hyperglycemia (without preexisting diabetes or on corticosteroids) underwent testing for HbA(1c) levels, two fasting PG levels, and an outpatient oral glucose tolerance test (OGTT) if necessary. RESULTS: Of the patients, 50 (9.8%) met the inclusion criteria. Of these, 70% (n = 35) completed the study, and 60% (n = 21) were diagnosed with diabetes. Patients with diabetes had higher HbA(1c) levels than subjects without diabetes (6.8 +/- 0.4 vs. 5.3 +/- 0.1%, P = 0.002). An HbA(1c) level >6.0% was 100% specific (14/14) and 57% sensitive (12/21) for the diagnosis of diabetes. When a lower cutoff value of HbA(1c) at 5.2% was used, specificity was 50% (10/21) and sensitivity was 100% (7/14). CONCLUSIONS: In acutely ill patients with random hyperglycemia at hospital admission, an HbA(1c) >6.0% reliably diagnoses diabetes, and an HbA(1c) level <5.2% reliably excludes it (paralleling the operating characteristics of the standard fasting glucose measurements); however, the rapidity of the HbA(1c) level can be useful for diabetes case finding and treatment initiation early in the hospital course.

Effects of krill oil on endothelial function and other cardiovascular risk factors in participants with type 2 diabetes, a randomized controlled trial.

OBJECTIVE: The purpose of this trial was to evaluate the effect of krill oil supplementation, a source of ω-3 fatty acids, on cardiovascular disease risk factors and blood glucose control among participants with type 2 diabetes. RESEARCH DESIGN AND METHODS: A randomized, double-blind controlled cross-over trial was employed. Outcomes assessed were: endothelial function, blood lipids, glucose, glycated hemoglobin, serum antioxidant level, C peptide, and calculated Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) scores. Participants were randomized to either krill oil or olive oil supplementation for 4 weeks, underwent a 2-week washout period, and then crossed to the other supplementation for 4 weeks. All participants were then offered an additional 17 weeks of krill supplementation. Testing occurred at 3 time points: baseline, after first supplementation, and after second supplementation. Testing also occurred after an optional 17 weeks of krill oil supplementation. Difference scores were calculated for each participant in both sequences (ie, differences in outcome measures in the first and second period of the sequence). The mean and SD of the scores in the 2 sequence groups were used to test for differences between treatment effects at a significance level of p<0.05. RESULTS: A total of 47 participants were included in the initial cross-over study. Participants who received krill oil for 4 weeks had an improvement in their endothelial function and a reduction in blood C peptide levels and HOMA scores as compared with the olive oil. A total of 34 participants completed the additional 17-week supplementation period. When compared with their respective baseline measures, these participants had a statistically significant improvement in endothelial function and blood high-density lipoprotein (HDL). CONCLUSIONS: Krill oil may lead to moderate improvement of cardiovascular risks, specifically endothelial dysfunction and HDL in patients with type 2 diabetes. TRIAL REGISTRATION NUMBER: Registered with ClinicalTrials.gov: NCT02091193.

Spontaneous subserosal venous rupture overlying a uterine leiomyoma. A case report.

BACKGROUND: Patient age, parity and leiomyoma size are considered risks for venous rupture overlying a leiomyoma. CASE: A 28-year-old woman presented with abdominal pain and decreasing hematocrit from spontaneous rupture of a uterine leiomyoma vein. CONCLUSION: Congestion of a vein overlying a leiomyoma, irrespective of the patient's age or parity or size of the leiomyoma, is a risk factor for rupture.

New insights into stages of lyme disease symptoms from a novel hospital-based registry.

BACKGROUND: Western Connecticut Health Network created the Lyme Disease Registry in response to the community's request and clinical need for more Lyme disease research. The registry includes acute, recovered, and persistently symptomatic patients to better define the different stages of the disease. The design of the registry was guided by community and clinician input through a community-based participatory research process. METHODS: Registry participants are asked questions regarding their diagnosis, symptoms, treatments, recovery, and satisfaction with the Registry. A blood specimen is also collected and stored at the initial appointment. RESULTS: The Lyme Disease Registry has enrolled 256 participants, 24% are acute cases, 45% are persistently symptomatic cases, and 31% are recovered cases. The symptoms experienced by the group of patients with persistent symptoms had unexpectedly strong overlap with those experienced by acutely infected patients. CONCLUSION: The difference between symptoms in the acutely infected patients and those experiencing persistent symptoms is not as large as initially thought.
