Impact of coronavirus disease 2019 on ENT clinical practice and training: the resident's perspective

BACKGROUND

The arrival of the coronavirus disease 2019 pandemic disrupted life suddenly and forcefully, and healthcare systems around the world are still struggling to come to terms with it. This paper reviews the impact of the pandemic on ENT practice and training.

METHODS

The present manuscript was developed as a narrative review to examine the role of otorhinolaryngologists in the management of the pandemic, and assess its impact on practice and training in the specialty.

RESULTS

Otorhinolaryngologists handle secretions of organs implicated in disease transmission, leaving them particularly vulnerable even while performing simple procedures. Although the pandemic increased skill expectations, it simultaneously reduced learning opportunities for trainees. In addition, attention to emergencies has been delayed. Further, the suspension of elective procedures has affected patients with malignancies.

CONCLUSION

While planning service resumption, provisions need to be made for protective equipment and training; improving teleconsultation services will help provide sustainable care during further waves.

Longterm effects of rotational night shift work on expression of circadian genes and its association with postprandial triglyceride levels - A pilot study

Abnormalities of lipid metabolism in the form of high fasting as well as postprandial triglyceride levels immediately after night shift work and under simulated night shift conditions have been reported in the literature. Whether dysregulation of circadian genes in the long term is associated with abnormal triglyceride metabolism has not been previously investigated. This pilot study aimed to investigate the long-term effect of rotational night shift work on the expression of circadian genes among healthcare workers and to ascertain the association between the expression of circadian genes and postprandial triglyceride and insulin resistance parameters. The study was conducted on two groups of healthcare workers (n = 20/group). Group 1 included day shift workers who had not done night shift duty during the past one year or ever. Group 2 included healthcare workers doing rotational night shift duties (≥4 night shift duties/month). Fasting blood samples were collected at 08:00 h to study the expression of circadian genes CLOCK, NPAS2, BMAL1, CRY1, CRY2, PER1, PER2, PER3, REVERBα, and biochemical parameters after which a standardized fat challenge test was done to measure postprandial triglyceride levels. Study of Group 2 individuals was conducted after a minimum of one week after the last night shift duty. Expression of CLOCK, NPAS2, PER1, PER3, and REV-ERBα genes was higher in Group 2 compared to Group 1 subjects, and expression of BMAL1 and CRY1 genes were lower in Group 2 compared to Group 1. Several of these genes showed significant correlations with postprandial triglyceride and insulin resistance parameters in Group 2 but not in Group 1 subjects. The present study showed altered expression of several circadian genes in healthcare workers involved in rotational night shift duties associated with postprandial triglyceride and insulin resistance parameters. This study therefore suggests that long term circadian gene dysregulation could have serious metabolic consequences in individuals engaged in rotational night shift duties.

Study of oestrogen and progesterone receptors in meningiomas by a technique utilizing the binding hormones in a polymerized state

Forty six cases of meningiomas were studied by utilizing oestrogen and progesterone hormone bound to fluroscent-iso-thiocynate (FITC) for the presence of oestrogen and progesterone receptors. Oestrogen receptors were present in 33% cases and only one fourth of these showed strong positivity. Progesterone receptors were positive in 41% cases, and more than half of these showed strong positivity. Thus this study revealed higher positivity rate for progesterone receptors than oestrogen receptors.
