Knowledge, attitude and practice of wearing mask in the population presenting to tertiary hospitals in a developing country.

BACKGROUND: In the era of COVID-19 where there is emphasis on the importance of wearing a mask, wearing it rightly is equally important. Therefore, the purpose of this study was to assess the knowledge, attitude and practice of wearing a mask in the general population of a developing country at three major tertiary care hospital. MATERIALS AND METHODS: Participants of this cross-sectional study were patients and attendants at three major tertiary care hospital of Karachi Pakistan. Selected participants, through non-probability convenient sampling technique, were interviewed regarding knowledge, attitude, and practice of wearing mask using an Urdu translated version of a questionnaire used in an earlier study. Three summary scores (0 to 100) were computed to indicate participants' mask wearing practice, technique of putting it on, and technique of taking if off. Collected data were analyzed with the help of IBM SPSS version 19. RESULTS: A total of 370 selected individuals were interviewed, out of which 51.9% were male and mean age was 37.65±11.94 years. For more than 90% of the participants, wearing a face mask was a routine practicing during the pandemic. The mean practice score was 65.69±25.51, score for technique of putting on a face mask was 67.77±23.03, and score of technique of taking off a face mask was 51.01±29.23. Education level of participant tends to have positive relationship with all three scores, while presence of asthma or chronic obstructive pulmonary disease (COPD) as co-morbid had negative impact on mask wearing practice. CONCLUSION: We have observed suboptimal knowledge, attitude and practice of wearing mask among the selected individuals. There is a continued need to spread awareness and educate general population about the importance of using a face mask, as well as the proper technique of wearing and taking off a face mask.

Impact of COVID­19 infection in patients with neurodegenerative diseases with particular focus on Alzheimer's and Parkinson's disease.

Neurodegenerative disorders (NDD) are chronic neurological diseases characterized by loss and/or damage to neurons along with the myelin sheath, and patients are at higher risk of severe infection with the SARS­CoV­2. A comprehensive literature search was performed using relevant terms and inclusion­exclusion criteria. Recent articles, subjects older than 50 years, and articles written in the English language were included, whereas letters to the editor and articles related to pregnant women were excluded from the review study. COVID­19 appears to damage angiotensin­II receptors which cause natural killer cells to lose the ability to clear virus­infected cells, owing to worse outcomes in patients with NDD. COVID­19 can worsen the symptoms of Alzheimer's disease. In addition, COVID­19 worsens drug­responsive motor symptoms in Parkinson's disease (PD) and other symptoms like fatigue and urinary complaints. Vitamin D is essential in decreasing pro­inflammatory and increasing anti­inflammatory cytokines in ongoing COVID­19 infections and reducing angiotensin receptors and, hence, decreasing COVID­19 infection severity. Telemedicine shows promise for patients with NDD but is yet to overcome legal issues and personal barriers. COVID­19 has a significant effect on neurodegenerative conditions, which appears partly to the nature of the NDD and the neuro­invasive capabilities of the SARS­CoV­2. The protective role of vitamin D in patients with NDD further supports this hypothesis. Modifications in current health care, like the telemedicine platform, are required to address the increased risk of serious infection in this population. Further studies will be required to clarify conflicting reports in many fields.

Antifungal Drugs Shortage in India amidst Looming Increase in Invasive Fungal Infections among COVID-19 Patients: An Impending Crisis.

The widespread prevalence of fungal infections in the second wave of COVID-19 pandemic could be owed to ubiquitous and injudicious use of steroids and immunosuppressive nature of the virus. However, these fungal infections also meant increased use of antifungal drugs, hence endangering their supply. Amphotericin B is the first line drug for mucormycosis which was declared as an epidemic in India during the second wave. With the increasing demand of the drug, came challenges to manufacture and supply large quantities of the drug and exploitation by creating a black market and spread of false information and imprudent usage. It is of utmost importance to be prepared with adequate supply all over the nation and implementing safety regulations in manufacturing and supply of large quantities of drugs during the demanding times and make them accessible at a reasonable rate.

Prevalence of Cardiac Risk Factors and Attitude toward Self-Risk Assessment among Cardiac Care Givers.

OBJECTIVE: Aim of this survey was to assess the prevalence of cardiovascular diseases (CVD) risk factors and attitude toward self-risk assessment among cardiac care physicians (who did not have CVD history), at a tertiary care cardiac center in Pakistan. DESIGN: In this survey we included cardiac care givers who had a minimum of 1 year of working experience in a cardiac care center. PARTICIPANTS: Participants with self-reported history of established diagnosis of CVD were excluded. Face-to-face interviews were conducted with the help of a structured questionnaire which consisted of demographic information, data regarding established CVD risk factors, self-awareness, and attitude toward CVD risk assessment. RESULTS: A total of 126 participants were interviewed, out of which 20.6% (26) were females and mean age was 36.1±7.6 years. The most prevalent CVD risk factor was family history of CVD (33.3%) followed by smoking (14.3%) and 23.8% had body mass index of ≥27.5 kg/m2. Around 23% of the participants did not know their cholesterol levels, similarly more than 74% were not aware of their high-density lipoproteins levels. More than 76% had never assessed their CVD risk and more than 37% don't know or don't have any opinion about their own CVD risk. CONCLUSIONS: The present study reveals low prevalence of conventional cardiac risk factors and marginally higher tendency of modifiable risk factors, such as smoking and obesity, among the cardiac physicians. A large proportion of these cardiac physicians have not yet assessed their CVD risk.
