Altered Sleep Duration and Poor Quality of Sleep Among Pharmacy Students Amidst COVID-19 Lockdown: A South-Indian Study.

Introduction/background: The nationwide lockdown enforced due to the spread of coronavirus disease-2019 had a definite impact on sleep. Objective: To observe any changes in the duration, pattern and quality of sleep among pharmacy students due to the lockdown. Methods: A google form-based cross-sectional and descriptive study was carried out after approval was obtained from the ethical committee in the month of July 2021 among 310 pharmacy students. The validated form was electronically administered after obtaining the informed consent. All the data pertaining to duration, pattern and quality of sleep before and during the lockdown was collected and analyzed using STATA version 16.0. Results and Discussion: Out of 310 participants, the study revealed an increase in the time needed to fall asleep (p value < 0.001) and in the total duration of sleep (p value < 0.001). A delay in the time of sleep in the morning (p value < 0.001) and at night (p value < 0.001) was also one among the many significant results. The incidences of jerky leg movements (p value < 0.001), snoring (p value < 0.001), frequent nightmares (p value < 0.001) and anxiety (p value < 0.001) were also increased as a direct effect of the lockdown. Conclusion: The study has confirmed the detrimental impact of the lockdown on sleep among pharmacy students. All attributes of sleep duration and sleep quality have achieved statistical significance signifying the need to develop cognitive behavioral interventions and prevent the worsening of mental health amidst the COVID-19 era.

Magnifying the importance of collecting race, ethnicity, industry, and occupation data during the COVID-19 pandemic.

The contagiousness of coronavirus disease-2019 (COVID-19) led to the imposition of historical lockdowns in various countries. No scientific mind could have made accurate projections of the tremendous impact that COVID-19 would have on nations, communities, and the global-wide economy. Meanwhile, millions of workers have lost their jobs, while healthcare workers are overwhelmed and are reaching a state of mental and physical exhaustion. With the uncontrollable spread, researchers have been working to identify factors associated with COVID-19. In this regard, race, ethnicity, industry, and occupation have been found to be predominant factors of interest. However, unfortunately, the unavailability of such information has been a difficult reality. Since race, ethnicity, and employment are essential social determinants of health and could serve as potential risk-factors for COVID-19, collecting such information may offer important context for prioritising vulnerable groups. Thus, this perspective aims to highlight the importance and need for collecting race, ethnicity, and occupation-related data to track and treat the racial/ethnic groups that have been most strongly affected by the COVID-19 pandemic. Collecting such data will provide valuable insights and help public health officials recognise workplace-related outbreaks and evaluate the odds of various ethnic groups and professions contracting COVID-19.

Was Sleep a Problem for the Elderly During COVID-19?

Over the past few decades, the population of geriatrics has seen an exponential rise and it is well known that the prevalence of chronic diseases and other associated comorbidities is higher among them which in turn, has an established association with sleep disorders. During these unprecedented circumstances, geriatrics are predisposed to be at an increased risk of sleep disorders due to the social isolation and loneliness imposed on them by the lockdowns. The fact that older adults are at a greater risk of contracting the virus due to the presence of comorbidities and the high virulence adds on to the existing risk of sleep disturbances. A lack of sleep in these circumstances has the potential to add on to the vicious cycle of sleep disorders predisposed by chronic disease and vice versa. Mental health, sleep and the presence of comorbidities are closely interlinked and they often tend to overlap. Research in sleep has established insomnia to be the most commonly diagnosed sleep disorder affecting almost 50% of the older adults which can subsequently, elevate their risk of falls. This prevalence of sleep disorders is hypothesized to increase during the second wave of the COVID-19 pandemic and a good sleep routine needs to be advocated for to improve the quality of life of this population. However, scientific evidence concerning this is scarce and this review aims to highlight the significance of sleep and urges its readers to undertake studies that investigate the architecture of sleep amongst older adults during the pandemic.

Corrigendum to "Role of UHRF1 in malignancy and its function as a therapeutic target for molecular docking towards the SRA domain" [Int. J. Biochem. Cell Biol. 114 (September 2019) 105558].

Cancer pathogenesis has been attributed to the minor and major disruptions in the cell cycle, with a key role being played by several of the recently discovered epigenetic factors. Lately, UHRF1 (Ubiquitin-like with containing PHD and RING Finger domains 1), an epigenetic regulator has been shown to be evidently over expressed in numerous malignancies through an in-depth review of literature. Molecular docking studies have found that existing drugs such as propranolol, naphthazarin and thymoquinone have favourable interactions with specific domains of UHRF1. However, these findings would need large scale clinical trials to confirm their potency and safety during chemotherapy. UHRF1 (Ubiquitin-like with containing PHD and RING Finger domains 1), an epigenetic factor, plays a crucial role as an important checkpoint in the cell machinery. Basic science continues to unravel multiple facets of this five domain protein which includes a detailed elucidation of its roles and mechanisms of interaction with various enzymes during DNA replication. The gene has recently begun to be also termed as the "Universal Oncogene" in response to the results of research conducted in heterogenous populations and in over 17 cancers displaying heightened mRNA and protein expression in breast, liver, lung, head and neck cancers and many more. This gene could therefore, be a potential biomarker for diagnosis and for the prediction of the prognosis and survival of the diseased. A scientifically established solution in the form of targeted treatment must follow such a discovery and therefore, several natural and synthetic compounds such as thymoquinone and the well-known antihypertensive, propranolol have been docked and reported to have favourable interactions with the SRA (Set and Ring Associated) domain of UHRF1 in this review. This comprehensive review is thus, a brief synopsis of details regarding the structure and heightened levels of UHRF1 in several malignancies. Furthermore, pharmacogenomic research revolving around this oncogene is a potential sphere for clinical studies to be conducted in much larger and heterogenous populations to not only validate these therapeutic docking results but to also to bring personalised medicine to the bedside for the benefit of the patients.

Role of UHRF1 in malignancy and its function as a therapeutic target for molecular docking towards the SRA domain.

The figure describes the location of UHRF1 (Ubiquitin-like with containing PHD and RING Finger domains 1) gene, mRNA and protein synthesis in the tumor cell and its structural domains with a focus on the docking of Naphthazarin on the SRA domain of UHRF1, resulting in reduction of tumor size.

Extranodal follicular dendritic cell sarcoma of the tonsil - case report of an epithelioid cell variant with osteoclastic giant cells.

Follicular dendritic cell sarcomas are rare neoplasms arising from the accessory cells of the lymph nodes, the follicular dendritic cells. They commonly occur in the lymph nodes, but have also been reported at extranodal sites (especially the tonsil). At both sites, there is usually a proliferation of spindled to ovoid cells, mimicking a mesenchymal tumor. Herein, we report a tonsillar tumor in a 50-year-old man, which was composed exclusively of large polygonal cells and numerous osteoclastic giant cells that resembled a giant cell carcinoma. The true nature of the tumor was revealed after an array of immunohistochemical stains. The patient is well 4 years after tonsillectomy.
