The association between physical activity and burnout among anaesthesia postgraduate trainees in Malaysia.

INTRODUCTION: Burnout is a psychological problem which is becoming more prevalent among medical professionals resulting in various negative outcomes. Physical activity has been found to be an effective method in alleviating burnout. The aim of this study was to determine the association between physical activity and burnout among postgraduate anaesthesia trainees in Malaysia. The study also intended to determine the level of physical activity among trainees, the factors affecting this practice, and the prevalence of burnout among anaesthesia trainees. MATERIALS AND METHODS: An online self-administered questionnaire was sent out to all postgraduate anaesthesia trainees between August 2020 and January 2021 via email and respondents were recruited on a voluntary basis. RESULTS: The prevalence of burnout among postgraduate anaesthesia trainees was high (54%). This prevalence was higher among trainees with low a level of physical activity. Half of the trainees (50.8%) engaged in moderate physical activity while only 12% reported a high level of physical activity. The postgraduate study year was found to be a significant factor affecting the practice of physical activity. CONCLUSION: There is a significant association between physical activity and burnout among postgraduate anaesthesia trainees in Malaysia. Physical activity has the potential to be an essential method of reducing burnout. Hence, measures should be implemented to improve the practice of physical activity among healthcare professionals in order to reduce workplace burnout.

Estimation of serum beta-carotene level in patients suffering from oral submucous fibrosis.

INTRODUCTION: Oral submucous fibrosis (OSMF), an insidious disease, has not been widely studied with respect to levels of serum beta-carotene (b-carotene). Hence present study aimed to estimate level of serum beta carotene in patients with OSMF. MATERIAL AND METHODS: 40 subjects (study subjects) with different grades of OSMF and 40 apparently healthy subjects without OSMF (control subjects with age and sex matched as that of study subjects) were screened for serum b-carotene levels employing Sobel and Snow's method. Subjects in both the groups had areca nut or gutkha chewing habit. RESULTS: Study subjects with OSMF showed lower levels of serum b-carotene as compared to control group subjects without OSMF. When the levels were compared between different disease stages, least levels of serum b-carotene were seen in Grade III OSMF subjects, as compared with Grade I and II subjects. Females showed higher levels of serum b-carotene than males in both the groups. Smokers showed depleted levels as compared to non-smokers in both groups. CONCLUSION: b-carotene plays an important role in the pathogenesis of OSMF, and its level decreases with disease progression.

Cardiac inflammatory myofibroblastic tumor: a comprehensive review of the literature.

Although inflammatory myofibroblastic tumors (IMTs) can be found in virtually every major organ, cardiac origin is rare. After recently providing care to a child who presented with a significant myocardial infarction, interest in this rare tumor was piqued. We describe a comprehensive review of cardiac IMT, including information on nomenclature, epidemiology, clinical features, pathogenesis, gross/histological features, immunohistochemical profile, diagnosis, treatment, and prognosis. Fifty-seven cases were identified in the literature. Interestingly, our case represents the seventh case of coronary artery involvement reported. Moreover, it was found that an initial presentation of sudden death most commonly involves the coronary arteries.

Micropapillary carcinoma of the urinary bladder: report of a case and review of its cytologic features.

Micropapillary carcinoma (MPC) is an aggressive variant of urothelial carcinoma. MPC has a propensity to invade lymphovascular spaces and detrusor muscle early in the disease that often leads to upstaging and/or lymph node metastasis in many cases at cystectomy. Its association with the usual high-grade urothelial carcinoma provides an easy recognition of malignancy in cytology specimens without attempt at separating or identifying the MPC component. This may be related to our limited familiarity of its cytologic features with only 4 cases described in the literature. We report another case of MPC and highlight its features in cytologic preparations including the presence of singly scattered tumor cells with high nuclear to cytoplasmic ratio and pleomorphic nuclei, clustered cells devoid of fibrovascular core (micropapillae), 3-dimensional cell aggregates, cytoplasmic vacuoles, and micropapillae exhibiting some features of low-grade urothelial neoplasm. Appreciation of these features may help facilitate its early diagnosis and hopefully a better outcome for these aggressive tumors.

Nodular histiocytic/mesothelial hyperplasia: a potential pitfall.

We present five cases of nodular histiocytic/mesothelial hyperplasia (two peritoneal, two pulmonary, and one pericardial) with identical microscopic features. All the lesions were biphasic and composed of cohesive monotonous epithelioid clusters of polygonal or oval cells with round or deeply grooved nuclei in association with darker cuboidal cells. Because of the increased cellularity and monotonous histologic pattern with some degree of cytologic atypia, neoplastic processes were seriously considered in the differential diagnoses. The majority of the cells marked as histiocytes by immunostain. A few scattered individual cells or small epithelial cell clusters were confirmed by calretinin stain to be mesothelial cells. The histologic patterns of the current lesions, irrespective of the location, were identical to nodular histiocytic/mesothelial hyperplasia. Histiocytic proliferations can be erroneously confused with primary mesothelial lesions or neoplasms such as granulosa cell tumor, eosinophilic granuloma, chronic myelogenous leukemia, and carcinoma. The purpose of this article is to describe the clinicopathologic features of nodular histiocytic/mesothelial hyperplasia and help familiarize pathologists with this lesion to prevent an erroneous diagnosis, particularly when it occurs in locations where mesothelial cells are not normally present.
