At the subcellular level, the cytoskeleton regulates cell structure, organelle movement, and cytoplasmic streaming. Autophagy is a process to remove unwanted biomaterials or damaged organelles through double membrane compartments known as autophagosomes. Autophagosome biogenesis requires vesicle trafficking between donor and acceptor compartments, membrane expansion, and fusion, which is very likely to be regulated by the cytoskeleton. Recent studies have demonstrated that by knocking out key actin-regulating proteins, autophagosome biogenesis is inhibited. However, the formation of ATG8 positive structures are not affected when the entire actin network is disrupted. Here, we discuss this paradox and propose the function of the actin cytoskeleton in plant autophagy. BACKGROUND The economic effects of the COVID-19 crisis are not like anything the U.S. health care system has ever experienced. METHODS As we begin to emerge from the peak of the COVID-19 pandemic, we need to plan the sustainable resumption of elective procedures. We must first ensure the safety of our patients and surgical staff. It must be a priority to monitor the availability of supplies for the continued care of patients suffering from COVID-19. As we resume elective orthopedic surgery and total joint arthroplasty, we must begin to reduce expenses by renegotiating vendor contracts, use ambulatory surgery centers and hospital outpatient departments in a safe and effective manner, adhere to strict evidence-based and COVID-19-adjusted practices, and incorporate telemedicine and other technology platforms when feasible for health care systems and orthopedic groups to survive economically. RESULTS The return to normalcy will be slow and may be different than what we are accustomed to, but we must work together to plan a transition to a more sustainable health care reality which accommodates a COVID-19 world. CONCLUSION Our goal should be using these lessons to achieve a healthy and successful 2021 fiscal year. The COVID-19 global pandemic has upended nearly every medical discipline, dramatically impacted patient care and has had far-reaching effects on surgeon education. In many areas of the country, elective orthopedic surgery has completely stopped to ensure that resources are available for the critically ill and to minimize the spread of disease. COVID-19 is forcing many around the world to re-evaluate existing processes and organizations and adapt to carry out business, of which medicine and education are not immune. Most national and international orthopedic conferences, training programs, and workshops have been postponed or canceled, and we are now critically evaluating the delivery of education to our colleagues as well as residents and fellows. This article describes the evolution of orthopedic education and significant paradigm shifts necessary to continue to teach ourselves and the future leaders of our noble profession. Hiccups (singultus) are reflex inspiratory movements that involve the swallowing reflex arc and can be classified as acute (48 h). A 62-year-old man with no history of malignancy or pulmonary disease presented to the Emergency Department with a four-day history of persistent hiccups. Other than episodic hiccupping, his physical examination was otherwise unremarkable. An abnormal chest X-ray led to a CT scan of the chest with IV contrast, which demonstrated regional, peripheral groundglass opacities of the upper lobes with small focal groundglass opacities scattered throughout the lungs. He was tested for COVID-19 per admission protocol, started on hydroxychloroquine, his hiccups improved, and he was discharged to home after 3 days. An emergency medicine physician should keep COVID-19 on the differential and be vigilant of exposure in atypical presentations. BACKGROUND Electrical storm is a dangerous condition presenting to the Emergency Department that requires rapid diagnosis and management. OBJECTIVE This article provides a review of the diagnosis and management of electrical storm for the emergency clinician. DISCUSSION Electrical storm is defined as ≥3 episodes of sustained ventricular tachycardia, ventricular fibrillation, or shocks from an implantable cardioverter defibrillator within 24 h. Patients may present with a wide array of symptoms. Initial evaluation should include an electrocardiogram with a rhythm strip and continuous cardiac monitoring, a medication history, assessment of hemodynamic stability, and identification of potential triggers. Management includes an antiarrhythmic and a beta blocker. Refractory patients may benefit from double-sequential defibrillation or more invasive procedures such as intra-aortic balloon pumps, catheter ablation and extracorporeal membrane oxygenation for critically ill patients. These patients will typically require admission to an intensive care unit. CONCLUSION Electrical storm is a condition associated with significant morbidity and mortality. It is important for clinicians to be aware of the current evidence regarding the evaluation and management of these patients. OBJECTIVES Acute renal colic is one of the common causes of referral to the hospitals. The aim of this study is to compare the efficacy of nebulized fentanyl with that of intravenous ketorolac in renal colic patients. MATERIALS & METHODS This double-blinded clinical study included 186 patients with acute renal colic who were referred to the emergency department of Besat Hospital, Iran. https://www.selleckchem.com/products/wnk463.html PATIENT SELECTION After selecting patients, according to study inclusion and exclusion criteria, they were divided into 2 groups of 93 using random block allocation method. The patients in the groups were treated with either nebulized fentanyl or intravenous ketorolac. The severity of pain was measured using the Numeric Pain Rating Scale (NPRS) of pain. The severity of pain at different times and demographic data were recorded. RESULTS One hundred and thirty four males and 52 females with a mean age of 42.95 ± 13.13 years were included in the study. The two groups were matched in terms of age, sex, and the severity of the pain before the treatment. Fifteen minutes following the treatment, the severity of pain was decreased in the ketorolac group but did not change in the nebulized fentanyl group. Thirty minutes after the administration of the drug, the severity of pain in the nebulized fentanyl group decreased. At any time, the severity of pain in the ketorolac group was lower than that of the nebulized fentanyl group. CONCLUSION Intravenous ketorolac had better analgesic effects in renal colic patients compared with nebulized fentanyl. Further studies that include complications and combinational therapy are required.
