Impact of the COVID-19 pandemic on patients with osteogenesis imperfecta

OBJECTIVES: On March 11, 2020, the WHO classified COVID-19 as a global pandemic. Measures to quell the pandemic included limiting non-essential activities including clinic visits and procedures. It is unclear if individuals with OI had disruptions in their access to healthcare or medications, and if such disruptions affected patients' symptoms. METHOD(S): A REDCap survey was distributed through the OI Foundation on August 31. Surveys completed through September 11 by individuals with OI or their caregiver are included in this analysis. Participants were asked to compare their symptoms and access to healthcare during the first 4 months of the pandemic to the 4 months before the pandemic. RESULT(S): 85 surveys were completed, and 6 were partially completed. The median age of participants was 40 years;35% were children. 32% of participants self-identified as having severe OI. Although most reported no changes in bone pain or fractures, 46% reported they were less likely to seek emergency medical care to treat a fracture, while 33% reported they were more likely to treat fractures at home (Fig 1A). There were delays in accessing all services, with greatest delays accessing dentistry (74%) and aquatic therapy (84%) (Fig 1B). 36% of participants receiving bisphosphonate infusions had delayed infusions because of the pandemic (Fig 1C). Of note, 50% of planned surgeries were delayed. CONCLUSION(S): Although many individuals with OI and their caregivers reported delays in accessing bone-related services/clinics during this 4-month period, there was not a concomitant increase in reported symptoms. This may have related to shelter-in-place restrictions and decreased activity. Limitations of this study include small sample size and potential selection bias because responses were obtained only from OIF members. To address these limitations, we are distributing the survey through healthcare providers of individuals with OI across major regions of the US from a variety of practice types including endocrine, orthopedics and multidisciplinary clinics. Furthermore, as the COVID-19 pandemic continues, we hope that this survey will provide information to address what aspects of healthcare may be in greatest need, as well as the modality through which services may be met.

Classic endocrine disorders: implications for cardiovascular disease

Chronic underproduction or autonomous oversecretion of hormone by endocrine glands has implications for the development and progression of cardiovascular disease. Hormonal effects on the vasculature may be direct, for example, tachycardia and atrial arrhythmias in hyperthyroidism, or mediated indirectly via adverse profiles of one or more major cardiovascular risk factors, for example, arterial hypertension in Conn's syndrome. The timescale of vascular effects may be relatively rapid, for example, resting tachycardia or atrial fibrillation precipitated by hyperthyroidism, or long-term, for example, atherosclerosis associated with acromegaly or hypopituitarism of long duration. The COVID-19 pandemic has highlighted clinically important interactions between the endocrine, metabolic, and cardiovascular systems. Endocrinologists and cardiologists will often need to collaborate closely in the management of patients with endocrine-associated vascular disease. © 2023 Elsevier Inc. All rights reserved.

Analysis of disease spectrum of hospitalized children during outbreak of coronavirus disease 2019 in pediatric department of a tertiary general hospital in Shanghai.

Objective To analyze the changes of disease spectrum in pediatric inpatients before and after the outbreak of coronavirus disease 2019 (COVID-19). Methods The data of gender, age, habitual residence, diagnosis and other relevant information of 1 931 hospitalized children in Department of Pediatrics, The First Affiliated Hospital of Naval Medical University (Second Military Medical University) from Feb. 2019 to Jan. 2020 (1 year before the COVID-19 epidemic) and 618 hospitalized children from Feb. 2020 to Jan. 2021 (1 year after the COVID-19 epidemic) were collected. The total number, habitual residence, gender and disease spectrum of hospitalized children 1 year before and 1 year after the COVID-19 epidemic were statistically analyzed. Results The number of hospitalized children decreased by 68.00% (1 313/1 931) 1 year after the COVID-19 epidemic. The number of hospitalized children from other provinces and cities was decreased (17.80%110/618vs 29.00%560/1 931) and there was significantly difference in the distribution of habitual residence of hospitalized children between 1 year before and 1 year after the COVID-19 epidemic (P<0.01). One year after the COVID-19 epidemic, the number of children with respiratory diseases decreased by 92.04% (971/1 055), and the proportion was also decreased (13.59%84/618vs 54.63%1 055/1 931);the number of children with endocrine system diseases increased by 20.71% (29/140), and the proportion was increased (27.35%169/618vs 7.25%140/1 931);the number of children with neonatal diseases decreased by 43.01% (166/386), but the proportion was increased (35.60%220/618 vs 19.99%386/1 931). Compared with 1 year before the COVID-19 epidemic, there were significant differences in the proportions of respiratory diseases, endocrine system diseases and neonatal diseases in hospitalized children 1 year after the COVID-19 epidemic (all P<0.01). The age distribution of hospitalized children 1 year before and 1 year after the epidemic of COVID-19 was different (P<0.01), and the number of hospitalized children was also different in different seasons (P<0.05). One year after the epidemic of COVID-19, the number of hospitalized children with respiratory diseases was decreased most significantly, and the number of children with pneumonia decreased by 93.71% (655/699), with a significant difference found in the proportions of pneumonia between 1 year before and 1 year after the COVID-19 epidemic (52.38%44/84vs 66.26% 699/1 055, P<0.05). Compared with 1 year before the COVID-19 epidemic, the proportion of endocrine system diseases such as short stature/growth retardation was decreased and the proportion of precocious puberty/early puberty development was increased 1 year after the COVID-19 epidemic (P<0.05). Conclusion The COVID-19 epidemic has led to a significant decrease in hospitalized children in department of pediatric, especially in the proportion of respiratory diseases, but it has led to an increase in hospitalized children with endocrine system diseases, suggesting that epidemic prevention and control measures can effectively reduce respiratory diseases requiring hospitalization, but may increase precocious puberty and early puberty development. These changes should be considered by department of pediatrics in general hospitals.Copyright © 2022, Second Military Medical University Press. All rights reserved.

Autonomic Dysfunction after Covid-19 Immunization - Case Report

Background: The infection caused by the SARS-CoV-2 continues affecting millions of people worldwide and vaccines to prevent the coronavirus disease (COVID-19) are considered the most promising approach for curbing the pandemic. Otherwise, cardiovascular and neurological complications associated with the vaccines were speculated and some few case reports were published. Objective(s): We describe a case of postural orthostatic tachycardia syndrome (POTS) after viral vector COVID-19 vaccination and the possible autoimmune process of the syndrome. Method(s): A 35-year-old female, without previous symptoms or comorbidities, developed intermittent palpitation, intense fatigue and dyspnea, compromising her daily activities, triggered by upright position, seven days following the second dose of the Oxford vaccine. Physical examination was normal, except for a heart rate (HR) increase of 33 beats/min from supine to standing position, with no significant change in blood pressure and reproduction of symptoms. Result(s): A 24-hour Holter monitoring revealed episodes of spontaneous sinus tachycardia correlated with palpitation and fatigue. Extensive diagnostic investigations excluded primary cardiac, endocrine, infectious and rheumatologic etiologies. The patient underwent an autonomic function test which demonstrated normal baroreflex sensitivity, as well as normal cardiovagal and adrenergic scores. Head-up tilt test showed persistent orthostatic tachycardia (HR increase from a medium of 84 beats/min in supine position to 126 beats/min during upright tilt), without hypotension, consistent with the diagnostic criteria for POTS. According to the current guidelines, general behavior recommendations, pharmacotherapy with low dose of propranolol associated with the autonomic rehabilitation were oriented. Along three months of follow-up, the patient reported a gradually improvement in her symptoms. Conclusion(s): POTS is a heterogeneous disorder of the autonomic nervous system characterized by orthostatic tachycardia associated with symptoms of orthostatic intolerance. Although the physiopathology of COVID-19 vaccine and autonomic disorders remains speculative, autoimmune response is one of the possible mechanisms. Based on clinic presentation, the time frame of symptom onset is consistent with other well-known post-vaccination syndromes, which may be an indicator of an autoimmune process induced by immunization. Further studies are needed to assess causal relationship between immunization and autonomic dysfunction.Copyright © 2023

Clinical features and acute management in adults

COVID-19 is a multisystem disease that requires holistic management. Most patients will experience mild symptoms including cough, fever and mild dyspnoea. A small proportion of patients will have severe manifestations including respiratory failure, ARDS and multiorgan failure. Extrapulmonary features are common and include gastrointestinal, thromboembolic, neurological, cardiac, renal, endocrine and dermatological manifestations. The care of COVID-19 patients requires close attention to these features. This includes respiratory support (such as supplemental oxygen, NIV and awake proning);fluid, electrolyte and nutrition management;prevention, detection and treatment of thrombotic events;management of diabetic complications;review of medications;appropriate use of antibiotics;and evidence-based use of therapeutic agents such as corticosteroids, antivirals such as remdesivir and other emerging therapies such as immunomodulating agents. Early planning for treatment escalation and decision making around the appropriateness of cardiopulmonary resuscitation are crucial as deterioration can be rapid. Prolonged symptoms occur in a minority of patients and longitudinal follow-up is required.Copyright © ERS 2021.

Relationship between COVID-19 infection and erectile dysfunction, a literature review examining the link and proposed mechanisms behind this phenomenon

It is now only in the wake of coronavirus disease 2019 (COVID-19) that we are beginning to understand many of the extra-respiratory manifestations of the condition. There is now growing evidence that erectile dysfunction (ED) is closely linked with the disease. We carry out one of the first literature reviews to consolidate the current evidence of the causal link between COVID-19 and ED and explore the proposed mechanisms that underpin this phenomenon. We carried out a literature search of the databases;PubMed (MEDLINE), Scopus, Web of Science and the Cochrane library. Search time frame was between December 2019 and March 2022. Only studies deemed of acceptable quality were included. Five studies were found highlighting the link between COVID-19 and ED. A further Nineteen studies were utilized to illustrate the proposed biological mechanisms underpinning COVID-19 related ED. Clear evidence has been documented through multiple studies internationally recognizing reduction in erectile scores and reduced sexual activity. It appears there is likely indirect and direct cytopathic effects on endothelial cells, in addition to hormonal and psychosocial factors. The associated ED is likely a result of a multitude of mechanisms including direct and indirect endothelial dysfunction, vasoactive cytokines, endocrine dysregulation, and psychosocial factors. This is the first literature review to delve into the likely underpinning mechanisms of the virus that drive ED.Copyright ©2023 The Author(s). Published by MRE Press.

Radiium systemic radiotherapy - 223 patients with mCRPC. Experience of the Republic of Bashkortostan

Introduction & Objectives: The incidence of prostate cancer, both in the world and in the Russian Federation, tends to increase. In the Republic of Bashkortostan in 2021, 699 patients with this diagnosis were registered. 19.6% of patients had stage IV disease at the time of diagnosis. 5818 patients were registered, of which 361 died within a year. The effectiveness of hormonal treatment of common prostate cancer has time limitations, after which there is a development of resistance to castration and progression of the disease. To date, drugs such as kabazitaxel, sipuleucel-T vaccine, abiraterone, enzalutamide and radium-223 have been approved for use in metastatic CRPC. The purpose of the work: analysis of the experience of systemic radiotherapyand Radium - 223 patients with mCRPC in the Republic of Bashkortostan in 2021. Material(s) and Method(s): Analysis of patients who received systemic radiotherapy Radium - 223 in the Republic of Bashkortostan according to medical documentation and research data. In 2021, Radiy-223 radiotherapy was performed on 7 patients diagnosed with mCRPC. Median age 63.14 years. All patients met the criteria for treatment, i.e. had castration-resistant prostate cancer with bone metastases, without visceral metastases. All patients had concomitant pathology from the cardiovascular system, respiratory tract, endocrine system. According to the previous surgical treatment, patients were distributed as follows: orchidectomy - 4, prostatectomy - 1 and 2 patients underwent tumor biopsy. By morphology: Glisson 6 - 2 patients, Glisson 7 - 1, Glisson 8 - 3, Glisson 10 - 1. 4 patients were referred to Xofigo for radiologically confirmed progression, 3 patients were progressingin height at PSA levels. Result(s): 1 patient previously received 1 line of systemic therapy, 5 patients received 2 lines, 1 patient received 3 lines of therapy. 6 patients received all 6 courses of radiotherapy, 1 patient did not complete treatment due to COVID 19. He is expected to complete therapy. All patients are currently alive with no signs of disease progression. Serious side effects were not registered. Conclusion(s): The "therapeutic window" for the prescription of radium-223 is the period before the appearance of visceral metastases and decline of the somatic status. To achieve the maximum benefit from the appointment of radium-223, it is necessary to conduct >=5 cycles of therapy, which is possible in 1-2 treatment lines. It is necessary to select patients carefully for radiotherapy - Radium 223.Copyright © 2022 European Association of Urology. Published by Elsevier B.V.

Post-COVID-19 syndrome.

Coronavirus disease 2019 (COVID-19) is a multisystemic disease caused by an emerging virus called SARS-CoV-2. Most patients with COVID-19 have mild symptoms, or they may be asymptomatic;however, some have severe manifestation, that can even be life threatening. Some patients that recovered from COVID-19 develop chronic symptoms (a clinical entity named post-COVD-19 syndrome), which includes neurological, psychiatric, hematological, cardiovascular, pulmonary and endocrine features. The management of these complications so far is supportive and includes symptomatic medical treatment and physical rehabilitation.Copyright © 2022 Comunicaciones Cientificas Mexicanas S.A. de C.V..

Manifestaciones extrapulmonares de COVID-19.

Coronaviruses are a large family of single-stranded ARN viruses that infect a wide variety of animals, including humans. The SARS-CoV-2 virus, which is responsible for the disease called COVID-19, has infected 27,249,308 people and caused 890,971 deaths worldwide until September 7, 2020. Considering the genetic similarities between SARS-CoV-2 and the epidemic coronaviruses SARS-CoV and MERS, presumably they share tropisms for specific cell lines and systemic conditions. The clinical and paraclinical characteristics of this new virus have been described in detail at the pulmonary level, although there is increasing evidence that it is a multisystemic agent. In the present work, we describe the extrapulmonary manifestations of COVID-19 reported to date, including hematological, cardiovascular, neurological, renal, muscular, ophthalmological, endocrine-metabolic, gastrointestinal, hepatobiliary, cutaneous and in special populations: pediatric (including multisystemic inflammatory syndrome) and pregnant women. It is essential to know the systemic complications of SARS-CoV-2 infection when managing these patients, given the potential risk to life of the most serious manifestations. Therefore, it is advisable to consider them in a targeted manner and provide timely treatment as far as possible.Copyright © 2022 Comunicaciones Cientificas Mexicanas S.A. de C.V..

Developing Contemporary Survivorship Clinic for Recipients of Hematopoietic Cell Transplantation: A Single Center Experience

Introduction: Survival after hematopoietic cell transplantation (HCT) has improved tremendously over the last few decades. HCT survivors are at increased risk of long-term complications and secondary cancers. This poses unique challenges to the HCT-related healthcare system given the growing need for survivorship care. Developing a HCT survivorship program with a dedicated clinic to survivors ensures equitable access to care and ongoing patient education. Herein, we describe our program survivorship model and our initial experience. Method(s): The Moffitt Cancer Center (MCC) survivorship clinic (SC) planning committee was initiated in September 2019. The SC was launched in January 2021 with the mission to provide high-quality, comprehensive, and personalized survivorship care and to empower patients and community health care providers with education and a roadmap for screening for late effects. The SC initially focused on allogeneic (allo) HCT patients and later opened to autologous (auto) HCT recipients in February 2022. HCT patients are referred by primary HCT team after HCT with an emphasis on preferred timeframe of initial SC visit no earlier than 3 months but less than 12 months from HCT. SC is located at 2 physical locations: main campus and satellite, with virtual visit options to account for the distance from MCC and COVID considerations. SC applies a consultative model. SC is staffed by dedicated advanced practice professional (APP), supervised by SC faculty. The scope of SC care includes but is not limited to prevention of infections (education, vaccinations), surveillance of late effects (endocrine, pulmonary function, cardiac, bone health), and general cancer screenings (breast, colon, skin cancer). Patients' clinical data from SC inception to August 2022 were reviewed. Result(s): From January 2021 to August 2022, a total of 138 patients were seen in SC. The majority were seen in person (62% in clinic, 38% by virtual visit). Median age was 58 years (range, 19-82). Median time to first SC visit was 21 months (range, 3-1464) after HCT. Allo HCT was the most common type of HCT seen in clinic (87%, n=120). Most common diagnoses were acute myeloid leukemia (43%, n=59), myelodysplastic syndrome (17%, n=23), and acute lymphoblastic leukemia (10%, n=14). Only 17 patients (12%) were seen in 2021 but the volume increased significantly in 2022. Currently there are more than 10 patients seen in SC per month. Conclusion(s): We report successful experience in launching a contemporary HCT SC despite the challenges of an ongoing COVID pandemic. As a stand-alone cancer center, we serve a wide geographical location with subspecialty and primary care providers dispersed throughout the community. Our consultative model and experience could provide a useful guide for other programs. In 2023, we plan to expand our SC to a broader population of patients receiving other cellular immunotherapies.Copyright © 2023 American Society for Transplantation and Cellular Therapy

West Nile Meningoencephalitis in a Patient with Leiomyosarcoma Presenting with Neutropenic Fever

Case Report: West Nile Virus (WNV) was first isolated from the West Nile district of Northern Uganda in 1937, but was first detected in the United States well over half a century later in 1999. The arthropod-borne virus has since persisted, with 2,401 cases reported to the CDC on average annually. The infection typically causes a nonspecific acute systemic febrile illness with occasional gastrointestinal and skin manifestations;however, in less than 1% of infected patients, it can cause severe and potentially fatal neuroinvasive disease, presenting as meningitis, encephalitis or acute flaccid paralysis. Immunosuppression is one of the risk factors associated with the development of neuroinvasive disease, and chemotherapy thus places patients at risk. Uterine leiomyosarcoma is a rare gynecological malignancy. Palliative chemotherapy is common in late stage disease, but may predispose patients to conditions that present as neutropenic fever, leading to a diagnostic conundrum. This is the first case report where patient with neutropenic fever was found to have West Nile neuroinvasive disease, so it is important to include West Nile disease in the differential diagnosis. Case Description: This is a case of a 45-year-old female with history of diabetes, hypothyroidism and recently diagnosed uterine leiomyosarcoma status post tumor debulking with metastasis on palliative chemotherapy with gemcitabine that presented to the Emergency Room for a fever of 103.8 degrees Fahrenheit. Given the history of advanced leiomyosarcoma, the patient was admitted for neutropenic fever with an absolute neutrophil count of 1000. During the hospitalization, the patient became acutely altered and confused. CT head without contrast and lumbar puncture were performed. Due to clinical suspicion of meningitis, she was started on broad spectrum antibiotics. Lumbar puncture revealed leukocytosis of 168 with lymphocytic predominance and elevated protein level in the cerebrospinal fluid, therefore acyclovir was started due to high suspicion of viral meningoencephalitis. An EEG showed severe diffuse encephalopathy as the patient was persistently altered. A broad workup of infectious etiology was considered including HIV, syphilis, hepatitis A, B, C, COVID-19, adenovirus, pertussis, influenza, WNV, HHV6, coccidiomycosis, aspergillus, and tuberculosis. Patient was ultimately found to have elevated IgM and IgG titers for West Nile Virus. Discussion(s): It is important to consider a broad spectrum of diagnosis in patients with metastatic carcinoma presenting with new-onset fever and acute encephalopathy. This includes working up for other causes of altered mental status including cardiac, neurologic, psychiatric, endocrine, metabolic, electrolyte, drug, and infectious etiology. While uncommon in the healthy population, WNV encephalitis should be on the radar for any patient who is immunocompromised or on immunosuppressive therapy, especially those who present with a neutropenic fever.

Addressing the Increasing Signs of Fatigue Post-Pandemic in Rock Springs, Wyoming

Purpose of Study: Fatigue is a confusing blend of feelings and actions that makes us feel strangely out of place. It has a significant negative impact on physical and emotional well-being, affecting the quality of life of patients. Fatigue has been poorly understood, due to its complex differential diagnosis, ranging from endocrine and respiratory to psychiatric disorders. In Wyoming, there has been an increase in anxiety and depression symptoms during the pandemic. Additionally, State budget cuts have caused a reduction in mental health services. Therefore, Primary care doctors must discuss, inform, and screen for mental health problems related to fatigue in the community due to the combination of rising mental health symptoms and declining mental health resources. Increasing screening for fatigue, using a Fatigue Assessment Scale (FAS), as an early intervention to address physical and/or mental Fatigue in primary care clinics, in Rock Springs, Wyoming. Methods Used: In primary care, there has been an increasing number of patients presenting with signs of fatigue, especially after the pandemic, which needs to be better understood. Currently, there is not a widespread gold-standard screening tool for Fatigue in primary care practice. Upon literature review, a simple three min, 10-item self-report questionnaire called the Fatigue Assessment Scale (FAS) addresses both physical and mental fatigue, ranging from lack of motivation to lack of energy. Summary of Results: FAS should be integrated into primary care clinics in Rock Springs, Wyoming with other screening questionnaires such as the anxiety/depression screening, to screen for and measure the severity of fatigue. Patients with physical fatigue along with shortness of breath and recent COVID exposure can benefit from pulmonary rehabilitation, whereas Patients with mental fatigue along with nausea, vomiting, and a recent chemotherapy session, can benefit from a counseling session and blood tests. Conclusion(s): FAS along with the history of present illness and physical exam will help guide the diagnosis with different clinical tests, blood tests, imagining studies, physical therapy, rehabilitation, and/or medications.

Menstrual disturbances following COVID-19 vaccination: A probable puzzle about the role of endocrine and immune pathways.

Menstruation is a monthly shedding of the uterine wall, presented by menstrual bleeding in women of reproductive age. Menstruation is regulated by fluctuation of estrogen and progesterone, as well as other endocrine and immune pathways. Many women experienced menstrual disturbances after vaccination against the novel coronavirus in the last two years. Vaccine-induced menstrual disturbances have led to discomfort and concern among reproductive-age women, such that some decided not to receive the subsequent doses of the vaccine. Although many vaccinated women report these menstrual disturbances, the mechanism is still poorly understood. This review article discusses the endocrine and immune changes following COVID-19 vaccination and the possible mechanisms of vaccine-related menstrual disturbances.

Parathyroid carcinoma presenting as severe hypercalcaemia responding to steroids.

A man in his 50s was referred with profound, symptomatic hypercalcaemia. He was diagnosed with primary hyperparathyroidism, confirmed on 99mTc-sestamibi scan. He was treated for the hypercalcaemia and referred to ear, nose and throat (ENT) surgeons for parathyroidectomy, which was delayed due to the COVID-19 pandemic. In the ensuing 18 months, he had five hospital admissions with severe hypercalcaemia requiring intravenous fluids and bisphosphonate infusions. During the last admission, hypercalcaemia was resistant to maximal medical management. Emergency parathyroidectomy was planned, but delayed due to intervening COVID-19 infection. Due to persistent severe hypercalcaemia (serum calcium: 4.23 mmol/L), he was commenced on intravenous steroids, following which serum calcium normalised. Subsequently, he underwent emergency parathyroidectomy, which normalised his serum parathyroid and calcium levels. On histopathological examination, a diagnosis of parathyroid carcinoma was made. On follow-up, patient remained well and normocalcaemic. In patients with primary hyperparathyroidism unresponsive to standard therapy, but responsive to steroids, underlying parathyroid malignancy should be considered.

Textual Research on Key Information of Ancient Classical Prescription Dayuanyin.

Dayuanyin,a representative prescription for the treatment of dampness pathogen lodging in pleurodiaphragmatic interspace syndrome,was first recorded in Treatise on Pestilence(<<>>)by Wu Youke in the Ming Dynasty for dealing with pestilence,and it still plays an important role in the treatment of coronavirus disease 2019(COVID-19)differentiated into dampness stagnating in lung syndrome. The related original ancient records were retrieved from the Chinese Classics of Traditional Chinese Medicine(Version 5.0),Full-text Database of Ancient Chinese Medicine Books,and Ancient Books of Traditional Chinese Medicine Database (http://www. gydc. ac. cn:81/),with 'Dayuanyin' and 'Dayuansan' as the search terms,followed by statistical analysis and textual research. The composition,dosage,processing of original medicinal materials,efficacy, indications, processing and administration methods, modern basic research, and clinical applications of Dayuanyin were summarized,so as to provide literature reference for its modern development and clinical application. The findings demonstrated that the composition in most medical records was identical with that of the original prescription,except that some records concerning Angelicae Dahuricae Radix and Tsaoko Fructus differed. In terms of dosage,it did not change much,with the only difference observed in Tsaoko Fructus. The processing methods of medicinal materials in Dayuanyin were not specified in historical records,so the raw medicinal materials were recommended. The processing and administration methods in the original record were basically followed in the later generations,except that some medical records chose Zingiberis Rhizoma Recens as the guide and changed the decocting amount and administration time. In terms of efficacy and indications, Dayuanyin was originally developed for dispelling pathogenic Qi away from the pleurodiaphragmatic interspace, but later employed for the treatment of such diseases as 'pestilence','epidemic malaria',and 'seasonal epidemic'. It was mainly indicated to 'epidemic diseases' with latent pathogen in pleurodiaphragmatic interspace as the pathogenesis and fever as the manifestation. In modern clinical application,ancients physicians considered 'fever' and 'powder-like tongue coating' as the important signs for this prescription. Modern physicians have utilized Dayuanyin for treating fever,diseases in the digestive,respiratory,urinary,and endocrine systems,skin diseases,pediatric diseases,as well as epidemic diseases like influenza,severe acute respiratory syndrome (SARS),and avian flu due to its good effects.Copyright © 2021, China Academy of Chinese Medical Sciences Institute of Chinese Materia Medica.

Effect of COVID-19 on Endocrine Glands Function.

A new hitherto unknown virus called severe acute respiratory syndrome coronavirus-2, SARS-CoV-2 for short, the causative agent of the disease COVID-19, has swept the world and become pandemic in its spread. Penetration of the virus into host cells is accomplished by attachment of the spike protein of the virus to its receptor, ACE-2, an enzyme of the renin angiotensin aldosterone system (RAAS), a zinc-dependent carboxypeptidase, which is expressed predominantly in the lung, heart, vascular endothelium, kidney, adipose tissue, thyroid, hypothalamus, pituitary, adrenal pancreas, ovary and testis. SARS-CoV-2 exerts its adverse effects on the function of all endocrine glands, either by direct (viral-toxic) or indirect (immune) mechanisms, with the strength of its action being modulated mainly by hormones of the pituitary-hypothalamic-adrenal axis and also involving the RAAS. This review discusses in detail the impact of SARS-CoV-2 on the endocrine system and possible future complications. The aim is to answer whether SARS-CoV-2 causes endocrine disease per se and whether an increase in the incidence of endocrine disease is expected after rechallenge with COVID-19.Copyright © 2022 Medical Information Center.

The Role of Estradiol in Modifying Circadian Rhythms, Sleep Regularity and Risk for Depression During the Pubertal Transition

Background: The pubertal transition (PT) is characterized by dramatic reproductive hormone fluctuations, a developmental circadian delay, and significant changes in sleep and wake patterns. The PT also marks an abrupt divergence between the sexes in risk for depression and sleep disorders that remains elevated for females across the reproductive lifespan, implicating ovarian hormones (i.e., estradiol (E2)) as a common pathway of risk. Notably, inconsistent schedules during the COVID-19 pandemic have contributed to greater sleep irregularity (especially for adolescents), which is associated with affective impairment and inferior clinical outcomes. The objective of this research is to characterize the pathophysiological impact of E2 on sleep disturbances, endocrine rhythm dysregulation and depressive symptoms in peripubertal females. Method(s): 44 peripubertal females (ages 11-14, within 1-year post-menarche) provided daily hormone (E1G-urinary metabolite of E2) and mood assessments for one menstrual cycle and completed an 8-day sleep assessment (actigraphy, daily sleep diaries), with cortisol and melatonin circadian measurement (over four days) starting at day 7 of the following menstrual cycle. Minute-to-minute consistency in sleep/wake state over 24-hrs was calculated to index sleep regularity (SRI). Result(s): A multiple regression model predicted depressive symptoms (CES-DC) from follicular menstrual cycle phase E1G-AUC, sleep regularity index (SRI), cortisol and melatonin AUCs (F(4,18) = 3.833, p=.020, R2=.46). E1G, cortisol-AUC (p<.05) and SRI (marginally, p=.08) contributed to the prediction. Conclusion(s): Results suggest that greater sleep irregularity, greater follicular estradiol and blunted cortisol may contribute to increased depressive symptoms in peripubertal females, providing mechanistic insight into the estradiol-related sleep and affect disruptions experienced during the pubertal transition.

The Role of Anxiety and Cortisol in Outcomes of Patients With Covid-19

Introduction: The outbreak due to Coronavirus Disease 2019 (COVID-19) is n global public health emergency and challenges psychological resilience. The central nervous system, endocrine system, and immune system are complex interacting systems. Cortisol has been implicated as the cause of a wide range of mental and physical health disorders;however, the impact of cortisol on outcomes in patients with COVID-19 is not clear.Methods: The current study enrolled patients with COVID-19 (onset of disease within 7 days of the first symptom) to evaluate the serum concentration of cortisol and levels of anxiety and depression using the Hospital Anxiety and Depression Scale (HADS) to investigate a possible relationship between cortisol, depression, and anxiety levels and outcomes of patients with COVID-19.Results: A total of 30 patients with COVID-19 were studied. The levels of cortisol and HADS score in patients who died of Covid-19 were significantly higher in comparison with surviving patients (P<0.017 and P<0.001 respectively). We also found that the HADS score was positively correlated with serum cortisol levels (r= 0.842, P=0.004).Conclusion: Our findings showed that stress and anxiety are associated with patients' outcomes. Psychological interventions can improve the mental health of vulnerable groups during the COVID-19 epidemic.

Physical human activity, immunity and COVID-19

Background: The global threat of COVID-19 outbreak and on the 11 March 2020, WHO acknowledged that the virus would likely spread to all countries across the globe and declared the coronavirus outbreak a pandemic which is the fifth pandemic since 20 century and this has brought human lives to a sudden and complete lockdown and the confirmed cases of this disease and deaths continue to rise in spite of people around the world are taking important actions to mitigate and decrease transmission and save lives. Objectives: To assess the effect of exercise and physical activity on the immunity against COVID-19. Methods: Collected electronic databases including (Medline, EMBASE, Google Scholar, PubMed and Web of Science) were searched without language restrictions to recognize all studies and reports on sports and physical activity related to COVID-19 due to alterations in the immune parameters. Results: Physical activity including sports and exercise induces obvious immune responses in many elements of the immune system whether transient or permanent that had a role in defense reaction against infection like COVID-19. This mediated through the nervous and endocrine systems that play a key role in determining exercise induced immune changes. Massive impact sports have on every aspect of our lives. Conclusions: Mild to moderate sports leads to stimulate an immune system that can subside COVID-19 infection and keep each other safe until this outbreak subsides and life is back to being greater than ever.

Vitamin D is a hormone rather than a vitamin in the strict sense. In fact, the active form 1,25 dihydroxyvitamin D3 [1,25(OH)2D3] exerts several effects on the inflammatory response of autoimmune rheumatic and infectious diseases. Low serum concentrations (less than 20 ng/ml) of 25-hydroxyvitamin D3 [25(OH)D3], the precursor of 1,25(OH)2D3, are common in COVID-19 patients and are associated with an impairment of the innate (neutrophils, monocytes/macrophages, dendritic cells) and adaptive (T and B lymphocytes, antibodies production) immune responses. Respiratory parameters (partial pressure of arterial oxygen-PaO2, partial pressure of arterial carbon dioxide-PaCO2, pressure of arterial oxygen to fractional inspired oxygen concentration-PaO2/FiO2), radiological pulmonary involvement, and serum concentrations of 25(OH)D3 were evaluated in sixty-five hospitalized COVID-19 patients (mean age 76 +/- 13 years) and sixty-five sex- and age-matched control subjects (CNT). COVID-19 patients showed significant lower 25(OH)D3 serum concentrations than CNT (median 8 ng/ml vs 16 ng/ml, p=0.001). 25(OH)D3 serum concentrations correlated positively with PaO2 (p=0.03) and PaO2/FiO2 (p=0.02). Moreover, 25(OH)D3 serum concentrations were significantly lower in COVID-19 patients with diffuse/severe radiological lung involvement (p=0.05) or multiple lung consolidations (p=0.0001) than in those with mild radiological lung involvement. Finally, significantly lower 25(OH)D3 serum concentrations were found in COVID-19 patients who died during hospitalization, compared to those who survived (p=0.05). In conclusion, vitamin D deficiency is associated with a more severe lung involvement and a higher risk of death in old COVID-19 patients.
