Adaptive mechanisms in quinoa for coping in stressful environments: an update.

Quinoa (Chenopodium quinoa) is a grain-like, genetically diverse, highly complex, nutritious, and stress-tolerant food that has been used in Andean Indigenous cultures for thousands of years. Over the past several decades, numerous nutraceutical and food companies are using quinoa because of its perceived health benefits. Seeds of quinoa have a superb balance of proteins, lipids, carbohydrates, saponins, vitamins, phenolics, minerals, phytoecdysteroids, glycine betaine, and betalains. Quinoa due to its high nutritional protein contents, minerals, secondary metabolites and lack of gluten, is used as the main food source worldwide. In upcoming years, the frequency of extreme events and climatic variations is projected to increase which will have an impact on reliable and safe production of food. Quinoa due to its high nutritional quality and adaptability has been suggested as a good candidate to offer increased food security in a world with increased climatic variations. Quinoa possesses an exceptional ability to grow and adapt in varied and contrasting environments, including drought, saline soil, cold, heat UV-B radiation, and heavy metals. Adaptations in salinity and drought are the most commonly studied stresses in quinoa and their genetic diversity associated with two stresses has been extensively elucidated. Because of the traditional wide-ranging cultivation area of quinoa, different quinoa cultivars are available that are specifically adapted for specific stress and with broad genetic variability. This review will give a brief overview of the various physiological, morphological and metabolic adaptations in response to several abiotic stresses.

The emergence of SARS-CoV-2 Omicron subvariants: current situation and future trends.

The SARS-CoV-2 Omicron variant (B.1.1.529) has been the most recent variant of concern (VOC) established by the World Health Organization (WHO). Because of its greater infectivity and immune evasion, this variant quickly became the dominant type of circulating SARS-CoV-2 worldwide. Our literature review thoroughly explains the current state of Omicron emergence, particularly by comparing different omicron subvariants, including BA.2, BA.1, and BA.3. Such elaboration would be based on structural variations, mutations, clinical manifestation, transmissibility, pathogenicity, and vaccination effectiveness. The most notable difference between the three subvariants is the insufficiency of deletion (Δ69-70) in the spike protein, which results in a lower detection rate of the spike (S) gene target known as (S) gene target failure (SGTF). Furthermore, BA.2 had a stronger affinity to the human Angiotensin-converting Enzyme (hACE2) receptor than other Omicron sub-lineages. Regarding the number of mutations, BA.1.1 has the most (40), followed by BA.1, BA.3, and BA.3 with 39, 34, and 31 mutations, respectively. In addition, BA.2 and BA.3 have greater transmissibility than other sub-lineages (BA.1 and BA.1.1). These characteristics are primarily responsible for Omicron's vast geographical spread and high contagiousness rates, particularly BA.2 sub-lineages.

Depression and anxiety among Pakistani healthcare workers amid COVID-19 pandemic: A qualitative study.

Objectives: The sudden COVID-19 crisis required a determined effort on the part of the healthcare workers (HCWs) and excessive workload increased the risk of depressive and anxious symptoms in frontliners. The aim of the study was to assess anxiety and depression levels among HCWs during times of pandemic and its potential aggravating factors. Materials and methods: A web-based survey was conducted to assess the mental health outcomes of healthcare workers and related factors during the COVID-19 pandemic. For assessing depression and anxiety, the Hospital Anxiety and Depression Scale (HADS) comprised of 14 items with seven items for depression and seven for anxiety were used. Results: Of all 436 participants, 158 (36.2%) showed noticeable symptoms of depression and 220 (50.4%) showed substantial anxiety symptoms. The majority of them were females. It has been observed in the study that female gender, young, and unmarried marital status are associated with higher scores. HCWs working in urban regions show more depressive symptoms. Mild depression and anxiety ratio are very common among participants (21.3%). Factors found to be associated with higher anxiety and depression are the increased number of deceased patients with lower family support. Conclusions: Altogether, the present study findings present concerns about the psychological well-being of all HCWs during the acute COVID-19 outbreak. Therefore, steps should be taken to protect them from mental exhaustion, so they may fight with more zeal against the infectious pandemic that has caused significant impacts worldwide.

Prevalence of depression and anxiety among general population in Pakistan during COVID-19 lockdown: An online-survey.

The present study's aim is to find the prevalence of two of the common indicators of mental health - depression and anxiety - and any correlation with socio-demographic indicators in the Pakistani population during the lockdown from 5 May to 25 July 2020. A cross-sectional survey was conducted using an online questionnaire sent to volunteer participants. A total of 1047 participants over 18 were recruited through convenience sampling. The survey targeted depression and anxiety levels, which were measured using a 14 item self-reporting Hospital Anxiety and Depression Scale (HADS). Out of the total sample population (N=354), 39.9% suffered from depression and 57.7% from anxiety. Binary logistical regressions indicated significant predictive associations of gender (OR=1.410), education (OR=9.311), residence (OR=0.370), household income (OR=0.579), previous psychiatric problems (OR=1.671), and previous psychiatric medication (OR=2.641). These were the key factors e associated with a significant increase in depression. Increases in anxiety levels were significantly linked to gender (OR=2.427), residence (OR=0.619), previous psychiatric problems (OR=1.166), and previous psychiatric medication (OR=7.330). These results suggest depression and anxiety were prevalent among the Pakistani population during the lockdown. Along with other measures to contain the spread of COVID-19, citizens' mental health needs the Pakistani government's urgent attention as well as that of mental health experts. Further large-scale, such as healthcare practitioners, should be undertaken to identify other mental health indicators that need to be monitored.

Spatial cluster analysis of COVID-19 in Malaysia (Mar-Sep, 2020).

Coronavirus disease 2019 (COVID-19) is the current worldwide pandemic as declared by the World Health Organization (WHO) in March 2020. Being part of the ongoing global pandemic, Malaysia has recorded a total of 8639 COVID-19 cases and 121 deaths as of 30th June 2020. This study aims to detect spatial clusters of COVID-19 in Malaysia using the Spatial Scan Statistic (SaTScan™) to guide control authorities on prioritizing locations for targeted interventions. The spatial analyses were conducted on a monthly basis at the state-level from March to September 2020. The results show that the most likely cluster of COVID-19 occurred in West Malaysia repeatedly from March to June, covering three counties (two federal territories and one neighbouring state) and moved to East Malaysia in July covering two other counties. The most likely cluster shows a tendency of having moved from the western part to the eastern part of the country. These results provide information that can be used for the evidence- based interventions to control the spread of COVID-19 in Malaysia.

Ultra-short-wave diathermy shortens the course of moderate and severe COVID-19: a randomized controlled trial (preprint)

Background COVID-19 patients have severe lung injury. The USWD could play a supportive role in relieving lung injury and enhance clinical recovery. Methods and findings The design was a single-center, evaluator blinded; 2-arm parallel design superiority randomized controlled clinical trial. Moderate and severe coronavirus-2 (SARS-CoV-2) positive patients with acute respiratory syndrome, Fifty patients were randomized (USWD, 25; control, 25) between February 18/2020 and April 20/2020. There were male 22 (44.0%) and female 28 (56.0%) with mean (SD) age 53(10.69). Time to clinical recovery (USWD 36.84 vs control 43.56, P = 0.03) was significantly shortened with a between-group difference of 6.72 days. The median SIRS score at day 28 was 0 (0-1) in the USWD group, while 0 (0-2) in the control group ( P = 0.011), and the seven-point scale at day 28 showed significant improvement in the USWD group (P = 0.003). While the rate of RNA negative conversion at day 7 (2/25 vs 7/25, p=0.054), day 14 (14/25 vs 18/25 p=0.239), day 21 (22/25 vs 18/25 p=0.279), and day 28 (25/25 vs 22/25 p=0.730) did not show statistical significance. Similarly, no significant differences were observed in the AI-assisted CT analysis. No treatment-associated adverse events or worsening of pulmonary fibrosis were found. Conclusions Among the 50 moderate and severe COVID-19 patients, the USWD as an adjunctive therapy to standard therapy could shorten the recovery course and enhance clinical improvement without aggravating pulmonary fibrosis. However, the study did not report statistical significance in the negative conversion rates of SARS-CoV-2 nucleic acid due to the small sample size and early termination, the findings of this study are limited.
