Prevalence and associated risk factors of burnout amongst veterinary students in Ghana.

This study was designed as a cross-sectional study to find out the prevalence and associated risk factors of burnout among veterinary students at Kwame Nkrumah University of Science and Technology (KNUST) in Kumasi-Ghana. A total of 74 veterinary students served as the respondents and were given online questionnaires which comprised questions on emotional exhaustion (EE), depersonalisation (DP) and reduced personal accomplishment (RPA). Data obtained were analysed using descriptive statistics, Chi-square test and regression analysis. Results indicated that on average, the EE and RPA were low with mean score of 12.72 ± 4.46 and 27.96 ± 7.94 whilst DP was high with a mean score of 20.72 ± 6.5 among veterinary students. The year of study had a significant effect (p = 0.000) on burnout with levels of high RPA (80%) and DP (70%) being more in the preclinical students as compared to the clinical students (RPA = 20%, DP = 30%). There was also a significant effect (p = 0.028) of the year of study and type of residence of the students on the high level of DP and RPA. Daily sleep hours of students had Daily sleep hours of the veterinary students were also indicated as a significant associated risk factor of burnout among veterinary students in this study as more less sleep hours (<6hours), causes high levels of DP and RPA. Age, gender and marital status, working status, exercise hours and weekly study hours of students did not count as significant predictive factors (p>0.05) of burnout.

Histological and immunohistochemical assessments of pneumonia in sheep slaughtered at Ibadan, Nigeria and Kumasi, Ghana.

There is a decline in sheep production and contribution to the economy. This study described the histological pattern, immunohistochemically demonstrate bacterial and viral agents of pneumonia in sheep slaughtered in metropolitan abattoirs in Nigeria and Ghana. A total of 805 (600 in Ghana and 205 in Nigeria) sheep lungs were examined for pneumonic lesions. Sections were fixed in 10% formalin for histological and immunohistochemical analysis. Pneumonia of 8.7% was in Ghana and 13.3% in Nigeria. The histological findings included bronchopneumonia (16/70), broncho-interstitial pneumonia (9/70), interstitial pneumonia (9/70) and proliferative pneumonia (7/70). Ten (14.3%) cases were positive for PPRV, PI3V, and RSV antigens while five (7.2%) were positive for multiple viral antigens; including two (PI3V and PPRV), two (RSV and PPRV), and one (PI3V and RSV). RSV was in interstitial pneumonia, PPRV and PI3V were in interstitial and broncho-interstitial pneumonia. PPRV and PI3V antigens 3 (4.4%) were in proliferative alveolitis. Mannheimia haemolytica (2) and Pasteurella multocida (2) infection were in combination with PPRV, RSV, and PI3V. Three sheep lungs (4.4%) were negative for viruses and bacteria. This study revealed ovine pneumonia is still a problem in West Africa, and multivalent vaccine incorporating some of these agents will be useful for the control.
