BACKGROUND Exercise rehabilitation after heart transplant is of major importance in order to improve physical capacity and prognosis.High-intensity interval training (HIIT) has repeatedly proven to be a highly efficient form of exercise for improving the physical capacity of both normal subjects and patients with coronary artery diseases (CAD) and heart failure. In contrast to the chronotropic response of a normal heart to exercise, a newly transplanted heart is denervated, which causes higher resting heart rate (HR) and reduced heart response (chronotropic incompetence). The HR response during exercise is mainly controlled by catecholamine’s from the adrenal glands, resulting in a significantly slower increase of the HR at onset of exercise, a reduced peak HR, and a delayed return towards resting values after cessation of exercise.  A study conducted in 2013 concluded  that high-intensity, aerobic training, especially interval-based training, is a favourable type of exercise that yields improvements in both peripheral and central factors.The review was conducted to determine the effect of HIIT on heart transplant patients.I PURPOSE Heart transplant patients have benefitted from aerobic exercises, but the protocol is mostly focussed on moderate intensity exercises. Chronotropic incompetence and safety have been two issues while considering high intensity exercises in heart transplant patients.HIIT has been proved to be effective in coronary artery disease and heart failure patients. METHODOLOGY Criteria for considering these studies for the review PRISMA guidelines of systematic review used. Physiotherapy Evidence Database scale used for assessing risk of bias. GRADE System of evaluation used for data extraction and quality assessment. "Mesh" terms used to search the article. Various databases like PubMed, Scopus, Google scholar, Cochrane screened. Inclusion and exclusion criteria stated. Studies done between 2010-2020 taken.Out of all the studies screened, which 3 studies fulfilled the full text eligibility and were included in the systematic review. RESULTS The heart transplant patients  demonstrated a  great improvement in VO2 peak, anaerobic threshold, peak expiratory flow, extensor muscle capacity, general health, systolic blood pressure and endothelial function post HIIT. One of the screened studies compared HIIT with moderate intensity exercises in heart transplant patients and found out that patients receiving HIIT demonstrated better improvement that moderate intensity exercises.The studies also emphasised that long term and community based HIIT is effective in improving the overall quality of life of the patients. CONCLUSION According to the three studies reviewed in this article, HIIT proved to be effective as exercise intervention on heart transplant patients. Abstract Figure. Forms of HIIT  Abstract Figure.

Background: In this study, we investigated the impact of COVID-19 on obstetric care in general hospitals and women's hospitals in Hubei, China. Methods:We sent a survey to investigate the changes of care for labor and delivery and to identify characteristics and outcomes of parturients contracted with COVID-19 between January and February of 2020 in Hubei.

ic first-pass metabolism [8] and direct hydrolysis of SA from intravenous administration. In addition, intranasal administration of appropriately formulated drugs can directly access the brain by bypassing the blood brain barrier and reducing off-target effects [9]. It is important to point out also that other potential neuroprotective agents are generally administered intravenously. In a stroke, the problem is lack of blood flow to a region of the brain, therefore an intravenous therapy would be severely limited in its access to the part of the brain that needs protection the most. An intranasal approach with a small hydrophobic molecule like SA can access all areas of the brain by simple diffusion.

Health care workers play a vital role in keeping others safe, relieving suffering and saving lives. No country, hospital or clinic can keep patients safe unless its health care workers are safe. Infections among health care workers can lead to a depleted workforce at a time when they are most needed [5]. Oxygen therapy is recommended for all severe and critical COVID-19 patients. Oxygen supply involves oxygen production, storage and transportation. Only high quality, medicalgrade oxygen should be given to patients [6]. Our hospital, Beijing Tongren Hospital affiliated to Capital Medical University in Beijing, China, is a large tertiary care hospital; with a medical care staff of more than 3600, with 1800 beds, and annual outpatient and emergency visits of 2.754 million. As a hospital both battling COVID-19 and maintaining necessary medical care, we experienced a shortage of medical supplies and obstacles in medical care. We set up fever clinics to manage potential COVID-19 patients, triaged regular patients in open-air environments and rescheduled medical procedures. No nosocomial infections have occurred in our hospital. We share our experience in the management of PPE, daily medical care during the pandemic and also discuss the medical oxygen supply in China and other countries during the most critical period. Training, guidelines, the privileges of PPE usage and managementWhen the outbreak that began in Wuhan in early January was officially announced, our purchasing department responded immediately and tried to order
