Echocardiography, lung ultrasound, and cardiac magnetic resonance findings in COVID-19: A systematic review.

BACKGROUND: The manifestations of COVID-19 as outlined by imaging modalities such as echocardiography, lung ultrasound (LUS), and cardiac magnetic resonance (CMR) imaging are not fully described. METHODS: We conducted a systematic review of the current literature and included studies that described cardiovascular manifestations of COVID-19 using echocardiography, CMR, and pulmonary manifestations using LUS. We queried PubMed, EMBASE, and Web of Science for relevant articles. Original studies and case series were included. RESULTS: This review describes the most common abnormalities encountered on echocardiography, LUS, and CMR in patients infected with COVID-19.

Role of Vitamins and Minerals in Improving Immunity during Covid-19 Pandemic - A Review

BACKGROUND The COVID-19 pandemic has brought attention to the role of the immune system. The immune system can be strengthened by diet, supplements and good hygiene practices. The immune system is comprised of different cells contained in the blood, lymph, and tissues that are distributed across the body. A large number of cells and even greater numbers of chemical messengers engage in the body's immune defence. In immune response blood cells, B-lymphocytes and T- lymphocytes play a vital role. The world health organization, urges people to follow a healthier lifestyle, saying it will increase their chances of a quick recovery. Proper nutrition is required for proper functioning of immune system. Therefore, healthy balanced diet is the best way to support the immune function. Vitamins and minerals are important ingredients of the diet that the body requires to work properly. Vit D is required in limited amounts to maintain good health. Vitamins and minerals together are also called micronutrients, as they are required in very small quantities. On the other hand, carbs, proteins and fats are altogether termed as macronutrients. In recent years, vitamins A, C, D, and E, believed to have an effect on the immune system, have gained significant attention because they are involved in enhancement of immune systems. Solely, vit-A is involved in proper functioning of eye, immune system and also takes care of skin and genes. In green leafy vegetables, carrots, pumpkin, melons and mangoes vitamins are present in form of pre-vitamins, and further converted into active vit A inside the human body. It is surprising that liver, yolk of egg, butter, whole milk, and cheese are active source of vitamin A. Having a healthy diet including lots of fruits, vegetables is a key component of healthy lifestyles and plays a crucial role in maintaining a properly functioning and efficient immune system to defend against infections and other diseases. All the data was assessed from online search (PubMed, Google Scholar). In this review article we concentrate on vitamins and minerals.
