Changes in lifestyle behaviour and dietary patterns among Iranian medical students during COVID-19 lockdown

Background: The COVID-19 pandemic has affected many aspects of human life, including physical and mental health. The public health measures to prevent COVID-19 transmission led to social isolation, physical inactivity, anxiety, depression, sleep disorders, obesity, and consumption of unhealthy food. Aims: To evaluate changes in lifestyle behaviour during the fifth wave of COVID-19 in Iranian medical students. Methods: This was a cross-sectional descriptive study. In September 2021, an online questionnaire containing 32 questions was administered to 1143 medical students in Teheran universities. Some 286 completed copies of the questionnaire were excluded because of incomplete answers. Descriptive statistics of central tendency measures and dispersion were used and independent t-test and a Chi-square test between two variables were conducted. Statistical analysis was performed using SPSS version 24. Results: A total of 462 (53.9%) students had COVID-19 during the fifth wave of the disease, 657 (76.7%) were deprived of social and sports activities, and 278 (32.4%) had difficulty completing their academic studies. Students who took vitamin supplements experienced lower levels of stress and 711 (83.0%) reported bodyweight change. There were significant relationships between bodyweight change, stress level and hospitalization due to COVID-19. There was a significant relationship between smoking, bodyweight change and hospitalization rate. A total of 426 (50.3%) students did not have a regular sleep–wake pattern, 701 (81.8%) spent more time using social media, 197 (23.0%) consumed more fast food, and 674 (78.6%) experienced stress or anxiety. Conclusion: There was an increased tendency towards unhealthy lifestyle among medical students in Tehran during COVID-19 lockdown. These findings can be useful in assessing lifestyle behaviours among students and in planning for improvements.

The green tea catechin epigallocatechin gallate inhibits SARS-CoV-2 infection.

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection has caused a pandemic with tens of millions of cases and more than a million deaths. The infection causes COVID-19, a disease of the respiratory system of divergent severity. No treatment exists. Epigallocatechin-3-gallate (EGCG), the major component of green tea, has several beneficial properties, including antiviral activities. Therefore, we examined whether EGCG has antiviral activity against SARS-CoV-2. EGCG blocked not only the entry of SARS-CoV-2, but also MERS- and SARS-CoV pseudotyped lentiviral vectors and inhibited virus infections in vitro. Mechanistically, inhibition of the SARS-CoV-2 spike-receptor interaction was observed. Thus, EGCG might be suitable for use as a lead structure to develop more effective anti-COVID-19 drugs.

Recommendations to Adapt and Strengthen Response Capacity at the First Level of Care during the COVID-19 Pandemic, September 2020

This document presents considerations to support decision-making and actions to help strengthen response capacity at the first level of care (FLC) based on the values laid out in the Strategy for Universal Access to Health and Universal Health Coverage (right to health, equity, and solidarity), the principles and attributes of primary health care, and integrated health services networks. It addresses discrimination based on ethnicity, gender, and gender identity, sexuality, socioeconomic level, geographical location, and disability as important factors that can increase the risk of infection for people in these groups, limit their access to services, undermine the broader response to COVID-19, and exacerbate underlying inequities. This document is aimed at health authorities, managers of health services networks, health program directors and coordinators, and managers of FLC staff, with a view to ensuring their health.

Potential anti-influenza effective plants used in Turkish folk medicine: A review.

ETHNOPHARMACOLOGICAL RELEVANCE: Due to the outbreaks such as SARS, bird flu and swine flu, which we frequently encounter in our century, we need fast solutions with no side effects today more than ever. Due to having vast ethnomedical experience and the richest flora (34% endemic) of Europe and the Middle East, Turkey has a high potential for research on this topic. Plants that locals have been using for centuries for the prevention and treatment of influenza can offer effective alternatives to combat this problem. In this context, 224 herbal taxa belonging to 45 families were identified among the selected 81 studies conducted in the seven regions of Turkey. However, only 35 (15.6%) of them were found to be subjected to worldwide in vitro and in vivo research conducted on anti-influenza activity. Quercetin and chlorogenic acid, the effectiveness of which has been proven many times in this context, have been recorded as the most common (7.1%) active ingredients among the other 56 active substances identified. AIM OF THE STUDY: This study has been carried out to reveal the inventory of plant species that have been used in flu treatment for centuries in Turkish folk medicine, which could be used in the treatment of flu or flu-like pandemics, such as COVID 19, that humanity has been suffering with, and also compare them with experimental studies in the literature. MATERIALS AND METHODS: The investigation was conducted in two stages on the subject above by using electronic databases, such as Web of Science, Scopus, ScienceDirect, ProQuest, Medline, Cochrane Library, EBSCO, HighWire Press, PubMed and Google Scholar. The results of both scans are presented in separate tables, together with their regional comparative analysis. RESULTS: Data obtained on taxa are presented in a table, including anti-influenza mechanism of actions and the active substances. Rosa canina (58.7%) and Mentha x piperita (22.2%) were identified as the most common plants used in Turkey. Also, Sambucus nigra (11.6%), Olea europaea (9.3%), Eucalyptus spp., Melissa officinalis, and Origanum vulgare (7.0%) emerged as the most investigated taxa. CONCLUSION: This is the first nationwide ethnomedical screening work conducted on flu treatment with plants in Turkey. Thirty-nine plants have been confirmed in the recent experimental anti-influenza research, which strongly shows that these plants are a rich pharmacological source. Also, with 189 (84.4%) taxa, detections that have not been investigated yet, they are an essential resource for both national and international pharmacological researchers in terms of new natural medicine searches. Considering that the production of antimalarial drugs and their successful use against COVID-19 has begun, this correlation was actually a positive and remarkable piece of data, since there are 15 plants, including Centaurea drabifolia subsp. Phlocosa (an endemic taxon), that were found to be used in the treatment of both flu and malaria.

Sources and routes of SARS-CoV-2 transmission in water systems in Africa: Are there any sustainable remedies?

Governments across the globe are currently besieged with the novel coronavirus (COVID-19) pandemic caused by SARS-CoV-2. Although some countries have been largely affected by this pandemic, others are only slightly affected. In this regard, every government is taking precautionary measures to mitigate the adverse effects of COVID-19. SARS-CoV-2 has been detected in wastewater raising an alarm for Africa due to the poor water, sanitation, and hygiene (WASH) facilities. Also, most countries in Africa do not have resilient policies governing sanitation and water management systems, which expose them to higher risk levels for the transmission of SARS-CoV-2. Therefore, this study unearthed the likely sources and routes of SARS-CoV-2 transmission in water systems (mainly wastewater) in Africa through a holistic review of published works. This provided the opportunity to propose sustainable remedial measures, which can be extrapolated to most developing countries in the world. The principal sources and routes of potential transmission of SARS-CoV-2 in water systems are hospital sewage, waste from isolation and quarantine centres, faecal-oral transmission, contaminated surface and groundwater sources, and contaminated sewage. The envisioned overwhelming impact of these sources on the transmission of SARS-CoV-2 through water systems in Africa suggests that governments need to put stringent and sustainable measures to curtail the scourge. Hence, it is proposed that governments in Africa must put measures like improved WASH facilities and public awareness campaigns, suburbanization of wastewater treatment facilities, utilizing low-cost point-of-use water treatment systems, legally backed policy interventions, and Community-Led Total Sanitation (CLTS). SARS-CoV-2 in water systems can be inactivated and destroyed by integrating ozonation, chlorination, UV irradiation, and sodium hypochlorite in low-cost point-of-use treatment systems. These proposed sustainable remedial measures can help policymakers in Africa to effectively monitor and manage the untoward impact of SARS-CoV-2 on water systems and consequently, on the health of the general public.

Estratégias governamentais para a garantia do direito humano à alimentação adequada e saudável no enfrentamento à pandemia de Covid-19 no Brasil / Government strategies to ensure the human right to adequate and healthy food facing the Covid-19 pandemic in Brazil

Resumo A pandemia de Covid-19 revelou a existência de ameaça concreta e imediata à segurança alimentar e nutricional (SAN), em especial de grupos vulnerabilizados. O estudo buscou identificar as estratégias governamentais implementadas no Brasil para prover o Direito Humano à Alimentação Adequada e Saudável em contextos de elevada vulnerabilidade social frente à Covid-19. Foi realizado um estudo transversal, com análise de documentos oficiais publicados entre 20 de março e 30 de julho de 2020 pela União, Distrito Federal, estados e capitais brasileiras, com foco em medidas que assegurem disponibilidade e acesso físico ou financeiro a alimentos. As estratégias implementadas envolvem fundamentalmente distribuição de alimentos e garantia de renda mínima. Foram instituídas: Renda Básica Emergencial (União); Programa de Aquisição de Alimentos (PAA) e auxílio financeiro emergencial (estados); programas de doação emergencial de alimentos (estados e municípios). Medidas existentes foram adaptadas frente à pandemia, como o Programa Nacional de Alimentação Escolar (PNAE), o Programa de Aquisição de Alimentos (PAA) nacional, a distribuição de alimentos e de cestas básicas. Embora importantes, essas estratégias têm alcance limitado e são insuficientes para assegurar a SAN.

Abstract The Covid-19 pandemic revealed a concrete and immediate threat to food and nutrition security (FNS), especially for vulnerable groups. This study aimed to identify government strategies implemented in Brazil to provide the Human Right to Adequate and Healthy Food in high social vulnerability contexts during the Covid-19 pandemic. A cross-sectional study was carried out, with analysis of official documents published between March 20 and July 30, 2020, by the Federal Government, Federal District, Brazilian states, and capitals, focusing on measures to ensure availability and physical or financial access to food. Strategies implemented mainly involve food distribution and minimum income assurance. The following were implemented: Basic Emergency Income (Federal Government); Food Acquisition Program (PAA), and emergency financial aid (states); emergency food donation programs (states and municipalities). Existing measures were adapted to the pandemic, such as the National School Food Program (PNAE), the National Food Acquisition Program (PAA), and the distribution of food and staple food baskets. While essential, these strategies have limited scope and are insufficient to ensure FNS.

Relapse of rare diseases during COVID-19 pandemic: bicytopenia in an adult patient with thiamine-responsive megaloblastic anaemia.

Thiamine-responsive megaloblastic anaemia (TRMA) is a syndrome associated with megaloblastic anaemia, diabetes mellitus and sensorineural deafness, due to mutations in the SLC19A2gene, which codes for a thiamine carrier protein. Oral thiamine supplementation is the main treatment. We report the case of a 19-year-old man known for TRMA, who presented in the emergency department with bicytopenia (haemoglobin 5,4 g/dL, thrombocytes 38×109/L) revealed by dyspnea and chest pain. Investigations excluded bleeding, hemolysis, coagulopathy and iron deficiencies. A recent infection and an acute coronary syndrome have also been eliminated. We later found out that thiamine treatment had been discontinued three months before, due to general confinement in Tunisia during the COVID-19 pandemic. Parenteral administration of 100 mg of thiamine daily resulted in the recovery of haematopoiesis within three weeks.

The management of "fragile" and suspected COVID-19 surgical patients during pandemic: an Italian single-center experience.

BACKGROUND: During Coronavirus disease (COVID-19) pandemic entire countries rapidly ran out of intensive care beds, occupied by critically ill infected patients. Elective surgery was initially halted and acute non-deferrable surgical care drastically limited. The presence of COVID-19 patients into intensive care units (ICU) is currently decreasing but their congestion have restricted our therapeutic strategies during the last months. METHODS: In the COVID-19 era eighteen patients (8 men, 10 women) with a mean age of 80 years, needing undelayable abdominal surgery underwent awake open surgery at our Department. Prior to surgery, all patients underwent COVID-19 investigation. In all cases locoregional anesthesia (LA) was performed. Intraoperative and postoperative pain has been monitored and regularly assessed. A distinct pathway has been set up to keep patients of uncertain COVID-19 diagnosis separated from all other patients. RESULTS: Mean operative time was 104 minutes. In only one case conversion to general anesthesia was necessary. Postoperative pain was always well controlled. None of them required postoperative intensive care support. Only one perioperative complication occurred. Early readmissions after surgery were never observed. CONCLUSIONS: On the basis of our experience awake laparotomy under LA resulted feasible, safe, painless and, in specific cases, the only viable option. For patients presenting fragile cardiovascular and respiratory, reserves and in whom general anesthesia (GA) would presumably increase morbidity and mortality we encourage LA as an alternative to GA. In the COVID-19 era, it has become part of our ICU-preserving strategy allowing us to carry out undeferrable surgeries.

Is mitochondrial bioenergetics and coenzyme Q10 the target of a virus causing COVID-19?

COVID-19 ‒ a coronavirus disease, affected almost all countries in the world. It is a new virus disease, nobody has prior immunity to it, human population is prone to infections. In March 11 2020, WHO declared the pandemic status. The main symptoms include: fever, dry cough and fatigue. Virus proteins need mitochondrial energy for their own survival and replication. Upon viral infections, mitochondrial dynamics and metabolism can be modulated, which can influence the energy production in the host cells. Coenzyme Q10 is an integral component of mitochondrial respiratory chain and the key component of mitochondrial ATP production. The exact pathobiochemical mechanism of the disease is unknown. Modulated mitochondrial dynamics and metabolism with lower CoQ10 levels in viral infections leads us to the hypothesis that one of the main pathobiochemical effects of SARS-Cov-2 virus could be mitochondrial bioenergetics dysfunction with CoQ10 deficit leading to the reduction of its endogenous biosynthesis. The mechanism might be virus induced oxidative stress causing a mutation of one or more of the nine COQ genes, resulting in primary CoQ10 deficiency. New perspective for patients with COVID-19 may be supportive targeting therapy with coenzyme Q10 to increase the energy production, immunity and decrease oxidative stress (Fig. 1, Ref. 51). Keywords: COVID-19, virus, mitochondrial bioenergetics, coenzyme Q10, oxidative stress.

Evidence Regarding Vitamin D and Risk of COVID-19 and Its Severity.

Vitamin D deficiency co-exists in patients with COVID-19. At this time, dark skin color, increased age, the presence of pre-existing illnesses and vitamin D deficiency are features of severe COVID disease. Of these, only vitamin D deficiency is modifiable. Through its interactions with a multitude of cells, vitamin D may have several ways to reduce the risk of acute respiratory tract infections and COVID-19: reducing the survival and replication of viruses, reducing risk of inflammatory cytokine production, increasing angiotensin-converting enzyme 2 concentrations, and maintaining endothelial integrity. Fourteen observational studies offer evidence that serum 25-hydroxyvitamin D concentrations are inversely correlated with the incidence or severity of COVID-19. The evidence to date generally satisfies Hill's criteria for causality in a biological system, namely, strength of association, consistency, temporality, biological gradient, plausibility (e.g., mechanisms), and coherence, although experimental verification is lacking. Thus, the evidence seems strong enough that people and physicians can use or recommend vitamin D supplements to prevent or treat COVID-19 in light of their safety and wide therapeutic window. In view of public health policy, however, results of large-scale vitamin D randomized controlled trials are required and are currently in progress.

Fear of childbirth in time of the new coronavirus pandemic.

OBJECTIVE: Reflect on how the new coronavirus pandemic triggered or accentuated the fear of childbirth in pregnant women and affected childbirth care practices. METHODS: Reflective analysis of women's pregnancy and childbirth experiences during the current pandemic, supported by the latest scientific evidence and recommendations on the topic. RESULTS: Pregnancy and childbirth are life-changing events for women, but during the new coronavirus pandemic, fear and uncertainty have taken on an unprecedented dimension in the negative way that many pregnant women have anticipated and experienced childbirth. FINAL CONSIDERATIONS: The current period has accentuated a chronic problem: a paternalistic system of health institutions in the approach to childbirth, dense with additional levels of fear in pregnant women. In this context, addressing the fear of childbirth means not giving up the promotion of safe and positive birth experiences for women.
