[Ocular symptoms in cerebellitis caused by COVID-19 : Cerebellitis, a less noticed disease with neuro-ophthalmological findings].
Schmidt, D
Die Ophthalmologie. 2023;(1):2-6
Abstract
The disease pattern of acute cerebellitis has been increasingly noticed in recent years. Two different courses had been observed. A mild form with slight ataxic disorders (as a postinfectious self-limiting disease) and a fulminant course of cerebellitis with cerebellar swelling, which compresses Sylvius' aqueduct, leading to an increased intracranial pressure with an obstructive hydrocephalus, and downward herniation of the cerebellar tonsils in the foramen magnum. In this case the course can be fatal if neurosurgical emergency treatment comes too late. Cerebellitis has been observed as a sequela to a virus infection and by autoimmune-mediated inflammation. Numerous publications were concerned with childhood cerebellitis but less commonly in adults. Neuro-ophthalmological findings were frequently described as nystagmus (horizontal gaze-evoked nystagmus, vertical nystagmus, downbeat nystagmus, periodic alternating nystagmus), papilledema, more rarely paresis of the abducens or facial nerve, photophobia and very rarely an opsoclonous-myoclonous syndrome. Cerebellitis with neuro-ophthalmological findings has repeatedly been described in adults during the coronavirus disease 2019 (COVID-19) pandemic.

Abstract
Almost immediately after the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus emerged, it was evident that people with chronic diseases, including diabetes, were disproportionately affected, with an increased risk of hospitalisation and mortality. Over the ensuing 2 years, the indirect effects of the pandemic on healthcare delivery in the short term have become prominent, along with the lingering effects of the virus in those directly infected. In the wake of the pandemic and without any evidence from high quality studies, a number of national and international consensus recommendations were published, which were subsequently rapidly updated based on observational studies. There have been unprecedented disruptions from both direct and indirect impacts of coronavirus disease-2019 (COVID-19) in people with diabetes. In this review, we summarise the impact of acute COVID-19 in people with diabetes, discuss how the presentation and epidemiology during the pandemic, including presentation of diabetic ketoacidosis and new-onset diabetes, has changed, and we consider the wider impact of the pandemic on patients and healthcare service delivery, including some of the areas of uncertainty. Finally, we make recommendations on prioritising patients as we move into the recovery phase and also how we protect people with diabetes for the future, as COVID-19 is likely to become endemic.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic has changed the practice of gastroenterology and how we perform endoscopy. As with any new or emerging pathogen, early in the pandemic, there was limited evidence and understanding of disease transmission, limited testing capability, and resource constraints, especially availability of personal protective equipment (PPE). As the COVID-19 pandemic progressed, enhanced protocols with particular emphasis on assessing the risk status of patients and proper use of PPE have been incorporated into routine patient care. The COVID-19 pandemic has taught us important lessons for the future of gastroenterology and endoscopy.

Abstract
Medicinal plants have a long track record of use in history, and one of them is Commiphora myrrh which is commonly found in the southern part of Arabia, the northeastern part of Africa, in Somalia, and Kenya. Relevant literatures were accessed via Google Scholar, PubMed, Scopus, and Web of Science to give updated information on the phytochemical constituents and pharmacological action of Commiphora myrrh. It has been used traditionally for treating wounds, mouth ulcers, aches, fractures, stomach disorders, microbial infections, and inflammatory diseases. It is used as an antiseptic, astringent, anthelmintic, carminative, emmenagogue, and as an expectorant. Phytochemical studies have shown that it contains terpenoids (monoterpenoids, sesquiterpenoids, and volatile/essential oil), diterpenoids, triterpenoids, and steroids. Its essential oil has applications in cosmetics, aromatherapy, and perfumery. Research has shown that it exerts various biological activities such as anti-inflammatory, antioxidant, anti-microbial, neuroprotective, anti-diabetic, anti-cancer, analgesic, anti-parasitic, and recently, it was found to work against respiratory infections like COVID-19. With the advancement in drug development, hopefully, its rich phytochemical components can be explored for drug development as an insecticide due to its great anti-parasitic activity. Also, its interactions with drugs can be fully elucidated.This review highlights an updated information on the history, distribution, traditional uses, phytochemical components, pharmacology, and various biological activities of Commiphora myrrh. Graphical summary of the phytochemical and pharmacological update of Commiphora myrrh.

Potential Benefit of Vitamin D Supplementation in COVID-19.
Stafford, A, White, ND
American journal of lifestyle medicine. 2023;(2):202-205
Abstract
Vitamin D is an important nutrient in the body that plays a vital role in immune system function. Several epidemiologic studies have shown that low vitamin D levels are found in a large percentage of COVID-19 patients with acute respiratory failure and that vitamin D levels may predict mortality in COVID-19 infection. Based on these findings, vitamin D supplementation may be an effective approach to preventing and/or treating COVID-19. Potential underlying mechanisms and clinical trial data evaluating the impact of supplementation in humans are described below.

Abstract
An outbreak of pneumonia caused by a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is called COVID-19 and has led to a pandemic worldwide. It is reasonable to investigate and control factors affecting disease severity and mortality. The relation between vitamin D and viral pneumonia has been previously reported. Vitamin D deficiency is common and may increase hospital admission and mortality rate in patients with COVID-19. This mini-review examines the pathways that show the association between vitamin D and COVID-19. On the other hand, it deals with the available evidence related to the relationship between vitamin D deficiency and the effect of vitamin D supplementation on the prevalence, severity, and mortality of COVID-19. Also, we described the pathophysiology of the organs' involvement in COVID-19 and the effect of vitamin D on these outcomes. Vitamin D strengthens the innate and adaptive immune system, modulates immune responses, prevents lung and cardiovascular system damage, and reduces thrombotic events. Vitamin D exerts these effects in several pathways. Vitamin D prevents virus entry and replication by maintaining the integrity of the body's physical barrier. Vitamin D reduces the damage to vital organs and thrombotic events by increasing the level of Angiotensin-converting enzyme 2 (ACE2), nitric oxide, and antioxidants or by reducing inflammatory cytokines and free radicals. Sufficient vitamin D may be reduced morbidity and mortality due to COVID-19. However, this issue should be investigated and confirmed by further research in the future.

Abstract
OBJECTIVES The outbreak of the COVID-19 pandemic has had wide-ranging outcomes on adolescents' well-being. However, less attention has been paid to the adolescent's mental health during the pandemic. The pandemic may impair adolescents' mental health through stress spillover from other family members, contextual and policy changes, and the disruption of everyday life routines. Therefore, our research is motivated by a need to address the relative scarcity of research examining adolescent mental health during the pandemic. CONTENT This systematic review was conducted through the medical database, Web of Science, Scopus, Medline, Embase, Google Scholar, and Cochrane databases for peer-reviewed, cross-sectional, cohort studies assessing the mental health status of adolescents during the Covid-19 virus pandemic from May 2020 till Dec 2022 without language restriction. Keywords were selected based on the Mesh terms and Emtree. SUMMARY Studies on coronavirus have revealed many significant psychological effects on teens of all ages. The most commom problems were on the stress and anxiety, sleep disorders, depression, post-traumatic stress disorder. Risk factors were concidered as prior mental health problem, female sexuality, fear of covid-19, nutrition, physical activity and listening the covid 19 news. OUTLOOK Considering the critical age of teenagers, the role of parents is vital. Health policy maker should support parents as a key factors to approprate care for adolescent. Parents should be educated on parenting methods during the covid pandemic to avoid irreparable damage of adolescent's mental health.

Abstract
Energy crisis and increasing rigorous management standards pose significant challenges for solid waste management worldwide. Several emerging diseases such as COVID-19 aggravated the already complex solid waste management crisis, especially sewage sludge and food waste streams, because of the increasingly large production year by year. As mature waste disposal technologies, landfills, incineration, composting, and some other methods are widespread for solid wastes management. This paper reviews recent advances in key sewage sludge disposal technologies. These include incineration, anaerobic digestion, and valuable products oriented-conversion. Food waste disposal technologies comprised of thermal treatment, fermentation, value-added product conversion, and composting have also been described. The hot topic and dominant research foci of each area are summarized, simultaneously compared with conventional technologies in terms of organic matter degradation or conversion performance, energy generation, and renewable resources production. Future perspectives of each technology that include issues not well understood and predicted challenges are discussed with a positive effect on the full-scale implementation of the discussed disposal methods.

Abstract
Caffeic acid phenethyl ester (CAPE), a main active component of propolis and a flavonoid, is one of the natural products that has attracted attention in recent years. CAPE, which has many properties such as anti-cancer, anti-inflammatory, antioxidant, antibacterial and anti-fungal, has shown many pharmacological potentials, including protective effects on multiple organs. Interestingly, molecular docking studies showed the possibility of binding of CAPE with replication enzyme. In addition, it was seen that in order to increase the binding security of the replication enzyme and CAPE, modifications can be made at three sites on the CAPE molecule, which leads to the possibility of the compound working more powerfully and usefully to prevent the proliferation of cancer cells and reduce its rate. Also, it was found that CAPE has an inhibitory effect against the main protease enzyme and may be effective in the treatment of SARS-CoV-2. This review covers in detail the importance of CAPE in alternative medicine, its pharmacological value, its potential as a cancer anti-proliferative agent, its dual role in radioprotection and radiosensitization, and its use against coronavirus disease 2019 (COVID-19).

Abstract
The outbreak of the coronavirus disease 2019 (COVID-19), caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has become an evolving global health crisis. Currently, a number of risk factors have been identified to have a potential impact on increasing the morbidity of COVID-19 in adults, including old age, male sex, pre-existing comorbidities, and racial/ethnic disparities. In addition to these factors, changes in laboratory indices and pro-inflammatory cytokines, as well as possible complications, could indicate the progression of COVID-19 into a severe and critical stage. Children predominantly suffer from mild illnesses due to COVID-19. Similar to adults, the main risk factors in pediatric patients include age and pre-existing comorbidities. In contrast, supplementation with a healthy diet and sufficient nutrition, COVID-19 vaccination, and atopic conditions may act as protective factors against the infection of SARS-CoV-2. COVID-19 vaccination not only protects vulnerable individuals from SARS-CoV-2 infection, more importantly, it may also reduce the development of severe disease and death due to COVID-19. Currently used therapies for COVID-19 are off-label and empiric, and their impacts on the severity and mortality of COVID-19 are still unclear. The interaction between asthma and COVID-19 may be bidirectional and needs to be clarified in more studies. In this review, we highlight the clinical evidence supporting the rationale for the risk and protective factors for the morbidity, severity, and mortality of COVID-19.
