Diabetes mellitus type 2 (DM2) and breast cancer (BrCa) are prevalent in Armenia. We investigated DM2, reproductive factors, and BrCa in a case control study of 302 women. Multiple logistic regression analyses revealed DM2 increased adjusted odds of BrCa by 5.53 (95% CI 1.34-22.81). Any birth was protective (adjusted OR=0.36, 95% CI 0.20-0.66). Each year delay in first pregnancy increased risk (adjusted OR=1.13, 95% CI 1.01-1.27) as did induced abortions (adjusted OR=2.86, 95% CI 1.02-8.04). Odds ratios were adjusted for age and body mass index (BMI), which confounded associations between DM2 and BrCa. We suggest our findings imply the need for further investigation in Armenian and in other populations with similar characteristics.
To assess the difference of pre- and post-training performance evaluation of continuing medical education (CME) courses in cardio-vascular diseases (CVD) management among physicians at primary health care facilities of Armenian regions we conducted an evaluation survey. 212 medical records were surveyed on assessment of performance before and after the training courses through a self-employed structured questionnaire. Analysis of survey revealed statistically significant differences (p < 0.05) in a number of variables: threefold increased recording of lipids and body mass index (p = 0.001); moderate increased recording of comorbidities and aspirin prescription (p < 0.012); eightfold increased recording of dyslipidemia management plan, twofold increased recording for CVD management plan and fivefold increased recording for CVD absolute risk (p = 0.000). Missing records of electrocardiography and urine/creatinine analyses decreased statistically significantly (p < 0.05). Statistically significant decrease was observed in prescription of thiazides and angiotensin receptor blockers/angiotensin converting enzyme inhibitors (p < 0.005), while prescription of statins and statins with diet for dyslipidemia management showed increased recording (p < 0.05). Similarly, we observed increased records for counseling of rehabilitation physical activity (p = 0.006). In this survey most differences in pre- and post-evaluation of performance assessment may be explained by improved and interactive training modes, more advanced methods of demonstration of modeling. Current findings may serve a basis for future planning of CME courses for physicians of remote areas facing challenges in upgrading their knowledge, as well as expand the experience of performance assessment along with evaluation of knowledge scores.
Introduction: Infection control at health facilities is an important part of TB control programmes. To assess the implementation of tuberculosis infection control (TB IC) measures and barriers hindering their implementation in TB health care facilities (HCFs) in Armenia; to report the feasibility of using the WHO recommended checklist.
Methodology: A cross-sectional survey using WHO TB-IC checklist and direct observations was conducted between January and May 2018.
Results: The survey included all 62 TB institutions in Armenia. TB HCFs in Armenia had implemented some recommended TB IC measures: offering IC training to staff (48%), shortening time to diagnosing TB to less than one day (29%) and ensuring good ventilation (60%). N95 respirators were available in all HCFs. However, barriers that hindered implementation of TB IC measures were: lack of training, a different incentive model for primary care doctors versus TB doctors and lack of space and poor conditions of the building.
Conclusion: The use of the standardized WHO checklist in this first evaluation of TB IC measures in Armenia was found to be useful and feasible in identifying areas of weak IC implementation and barriers to achieving good infection control. Other TB programs may benefit from the use of this model of assessment, based on the WHO checklist.
The results of an experimental investigation of electron beam spectral distribution after interaction with external electromagnetic waves in an undulator are given. The initial electron energy was 12 MeV, external electromagnetic wave power was 50 MW, the wavelength being 10 μm. A helical 20-cm-long undulator with a period length of 9.5 mm was used. The dependence of spectral distribution maximum change on undulator magnetic field strength was measured. The results are in good agreement with estimated findings taking into account the real parameters of the experimental setup. Electron energy maximum change was ±20 keV which is a result of electron acceleration or deceleration by the electromagnetic wave in the undulator.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
