The aim of this study was to assess the validity and reliability of the Serbian versions of the

(CBI) and the

(SBI) among fifth-year medical students at 5 universities in Serbia.

The study included 573 fifthyear medical students at 5 universities in Serbia. The research instrument consisted of SBI and CBI. The reliability of these instruments was assessed using an internal consistency measure (Cronbach's α), an intra-class coefficient (ICC) and factor analysis.

Cronbach's α for SBI was 0.83, including for exhaustion 0.73, for cynicism 0.70, and for inadequacy 0.48. The test-retest reliability (ICC) was 0.75. Cronbach's α for personal burnout on CBI was 0.89, for the faculty-related burnout 0.86, and for the faculty-members-related burnout 0.92. Cronbach's α for CBI was 0.93. The factor analysis for SBI showed 2 factors and for CBI 3 factors.

This study revealed that the Serbian versions of both SBI and CBI could be used for the assessment of burnout in this population.

The study evaluated the professional activity of patients after a total cementless hip replacement surgery performed at the age of ≤30 years.

The study group comprised 87 patients, with 95 total cementless hip replacements. The mean age was 25.7 years. The youngest patient was 17 years old, and the oldest 30 years old. The mean length of observation was 20.1 years, ranging 5-33 years. All patients underwent clinical and radiological evaluations before the surgery, and again in the third, sixth and twelfth months after the surgery. Further follow-up visits were performed every year. The tests were scored according to the Merle d'Aubigné and Postel (MAP) classification, as recommended by the Polish Society of Orthopaedics and Traumatology. Postoperative radiographs were used to assess the position of the endoprosthesis, and the degree of implant healing in the bone tissue. The data was subjected to statistical analysis.

Of the surveyed group, 67 patients were professionally active before the surgery 34 weless hip replacement is a valuable method of treating osteoarthritis in young patients. All of the patients who worked before the surgery returned to work in the same position and on the same employment conditions. Most of the previously-unemployed patients commenced employment following the procedure.

Mitral valve repair with papillary muscle approximation (MVr-PMA) for severe secondary mitral regurgitation (MR) decreases MR recurrence compared with MVr alone. This study assessed the effects of MVr-PMA on left ventricular (LV) remodeling and shape, systolic function and strain mechanics.

Forty-eight patients who underwent MVr-PMA for severe secondary MR and had follow-up echocardiograms available for review were identified. Student's t-test, linear regression modeling, and receiver-operating characteristic curves were used in the statistical analyses.

Median follow-up time was 14.9 months. MVr-PMA was associated with significant LV reverse remodeling with a smaller LV end-diastolic diameter, systolic sphericity index, and interpapillary muscle distance at follow-up. Nine patients (18.8%) experienced ≥ moderate recurrent MR. When compared recurrent MR patients at follow-up, those with durable MVr-PMA had a greater LV ejection fraction (32.8 vs 22.0%, p=0.03), a smaller end-diastolic diameter (59.6 vs 67.3 mm, p=0.03), systolic sphericity index (0.35 vs 0.47, p=0.03), and endsystolic interpapillary muscle distance (16.3 vs 21.1 mm, p=0.03). A durable MVr-PMA also resulted in stable global longitudinal strain when compared with pre-operative values, while the recurrent MR group experienced a further decline (no recurrent MR -8.4 vs -7.5%; recurrent MR -8.2 vs -5.4%; p<0.05). A pre-operative LV end-diastolic diameter ≥ 64 mm was a discriminative predictor of MR recurrence (sensitivity = 100%, specificity = 51%, AUC = 0.756, p = 0.02).

A durable MVr-PMA confers improved LV geometry and function, and stable LV mechanics. The extent of baseline LV remodeling identifies patients at risk for recurrent MR.

Device exchange to a newer generation left ventricular assist device (LVAD) offers the opportunity to benefit from improved adverse events profiles. We present the three year results of a patient cohort undergoing VAD upgrades to a new generation device focusing on outcomes and adverse events.

We present the first series of patients who underwent LVAD upgrade to HeartMate 3. All operations were performed less invasively. Follow-up time was three years after LVAD exchange.

Overall four HeartMate II and two HVAD patients underwent LVAD upgrade. In five cases severe infection of the VAD led to device exchange (83%, 5/6). Three year survival after LVAD exchange was 100% (6/6). https://www.selleckchem.com/products/wnt-c59-c59.html In the follow-up examinations one patient showed a single syncope and several low flow alarms (1/6). The remaining five patients showed no technical malfunctions of the LVAD or hemodynamic adverse events (5/6). Four out of five patients whose devices had to be changed due to an infection suffered a local re-infection (4/5), which, however, did not require any further surgical intervention. Four patients were successfully transplanted and two patients were still on device support at three years after LVAD exchange.

Three-year outcomes and adverse events after LVAD exchange to HeartMate 3 show excellent results. The superior hemocompatibility in terms of pump thrombosis makes the HM3 a favored choice in case of LVAD exchange due previous pump thrombosis. However, in cases of exchange due to device infection the risk of reinfection remains high.
