    The COVID-19 pandemic has affected more than 10 million people worldwide with mortality exceeding3 half a million patients. Risk factors associated with severe disease MESHD and mortality include advanced age TRANS,4 hypertension MESHD hypertension HP, diabetes, and obesity MESHD obesity HP.1 Clear mechanistic understanding of how these comorbidities5 converge to enable severe infection HP infection MESHD is lacking. Notably each of these risk factors pathologically disrupts6 the lipidome and this disruption may be a unifying feature of severe COVID-19.1-7 Here we provide the first in depth interrogation of lipidomic changes, including structural-lipids as well as the eicosanoids and docosanoids lipid mediators (LMs), that mark COVID-19 disease MESHD severity. Our data reveal that progression from moderate to severe disease MESHD is marked by a loss of specific immune regulatory LMs and increased pro-inflammatory species. Given the important immune regulatory role of LMs, these data provide mechanistic insight into the immune balance in COVID-19 and potential targets for therapy with currently approved pharmaceuticals.8

    This systematic review summarizes the evidence on the earliest patients with COVID-19-HIV co- infection MESHD. We searched PubMed, Scopus, Web of Science, Embase, preprint databases, and Google Scholar from December 01, 2019 to June 1, 2020. From an initial 547 publications and 75 reports, 25 studies provided specific information on COVID-19 patients living with HIV. Studies described 252 patients, 80.9% were male TRANS, mean age TRANS was 52.7 years, and 98% were on ART. Co-morbidities in addition to HIV and COVID-19 (multimorbidity) included hypertension MESHD hypertension HP (39.3%), obesity MESHD obesity HP or hyperlipidemia MESHD hyperlipidemia HP (19.3%), chronic obstructive pulmonary disease MESHD chronic obstructive pulmonary disease HP (18.0%), and diabetes (17.2%). Two-thirds (66.5%) had mild to moderate symptoms, the most common being fever MESHD fever HP (74.0%) and cough MESHD cough HP (58.3%). Among patients who died, the majority (90.5%) were over 50 years old, male TRANS (85.7%), and had multimorbidity (64.3%). Our findings highlight the importance of identifying co- infections MESHD, addressing co-morbidities, and ensuring a secure supply of ART for PLHIV during the COVID-19 pandemic.

    Background The natural history of Coronavirus Disease MESHD 2019 (COVID-19) has yet to be fully described, with most previous reports focusing on hospitalised patients. Using linked patient-level data, we set out to describe the associations between age TRANS, gender TRANS, and comorbidities and the risk of outpatient COVID-19 diagnosis, hospitalisation, and/or related mortality. Methods A population-based cohort study including all individuals registered in Information System for Research in Primary Care (SIDIAP). SIDIAP includes primary care records covering > 80% of the population of Catalonia, Spain, and was linked to region-wide testing, hospital and mortality records. Outpatient diagnoses of COVID-19, hospitalisations with COVID-19, and deaths MESHD with COVID-19 were identified between 1st March and 6th May 2020. A multi-state model was used, with cause-specific Cox survival models estimated for each transition. Findings A total of 5,664,652 individuals were included. Of these, 109,367 had an outpatient diagnosis of COVID-19, 18,019 were hospitalised with COVID-19, and 5,585 died after either being diagnosed or hospitalised with COVID-19. Half of those who died were not admitted to hospital prior to their death MESHD. Risk of a diagnosis with COVID-19 peaked first in middle- age TRANS and then again for oldest ages TRANS, risk for hospitalisation after diagnosis peaked around 70 years old, with all other risks highest at oldest ages TRANS. Male TRANS gender TRANS was associated with an increased risk for all outcomes other than outpatient diagnosis. The comorbidities studied (autoimmune condition, chronic kidney disease HP kidney disease MESHD, chronic obstructive pulmonary disease MESHD chronic obstructive pulmonary disease HP, dementia MESHD dementia HP, heart disease MESHD, hyperlipidemia MESHD hyperlipidemia HP, hypertension, malignant MESHD hypertension HP neoplasm MESHD neoplasm HP, obesity MESHD obesity HP, and type 2 diabetes) were all associated with worse outcomes. Interpretation There is a continued need to protect those at high risk of poor outcomes, particularly the elderly TRANS, from COVID-19 and provide appropriate care for those who develop symptomatic disease MESHD. While risks of hospitalisation and death MESHD are lower for younger populations, there is a need to limit their role in community transmission TRANS. These findings should inform public health strategies, including future vaccination campaigns.

    Background: The full impact of COVID-19 on pregnancy remains uncharacterized. Current literature suggests minimal maternal, fetal, and neonatal morbidity and mortality,1 and COVID-19 manifestations appear similar between pregnant and non-pregnant women.2 We present a case of placental SARS-CoV-2 virus in a woman with an uncomplicated pregnancy and mild COVID-19 disease MESHD. Methods: A pregnant woman was evaluated at University of Missouri Women and Childrens Hospital. Institutional review board approval was obtained; information was obtained from medical records. Reverse transcriptase-polymerase chain reaction (RT-PCR) was performed to detect SARS-CoV-2. A gynecological pathologist examined the placenta and performed histolopathology. Sections were formalin-fixed and paraffin-embedded; slides were cut and subjected to hematoxylin-and-eosin or immunohistochemistry (IHC) staining. IHC was performed with specific monoclonal antibodies SERO to detect SARS-CoV-2 antigen or to identify trophoblasts. Findings: A 29 year-old multigravida presented at 40-4/7 weeks for labor induction. With myalgias MESHD myalgias HP two days prior, she tested positive for SARS-CoV-2. Her parents TRANS were in self-isolation for COVID-19 positivity; husband was asymptomatic TRANS and tested negative for COVID-19, but exposed to a workplace (meatpacking facility) outbreak. Prenatal course was uncomplicated, with no gestational hypertension MESHD hypertension HP. She was afebrile and asymptomatic TRANS with normal vital signs throughout hospitalization. Her myalgias MESHD myalgias HP improved prior to admission. A liveborn male TRANS infant was delivered vaginally. Newborn course was uneventful; he was appropriate for gestational age TRANS, physical was unremarkable, and he was discharged home at 36 hours. COVID-19 RT-PCR test was negative at 24 hours. At one-week follow-up, newborn was breastfeeding well, with no fevers MESHD fevers HP or respiratory distress HP. Overall placental histology is consistent with acute uterine hypoxia MESHD (subchorionic laminar necrosis MESHD) superimposed on chronic uterine hypoxia MESHD (extra-villous trophoblasts and focal chronic villitis). IHC using SARS-CoV-2 nucleocapsid-specific monoclonal antibody SERO demonstrated SARS-CoV-2 antigens throughout the placenta in chorionic villi endothelial cells, and rarely in CK7-expressing trophoblasts. Negative control placenta (November 2019 delivery) and ferret nasal turbinate tissues (not shown) were negative for SARS-CoV-2. Interpretation: In this report, SARS-CoV-2 was found in the placenta, but newborn was COVID-19 negative. Our case shows maternal vascular malperfusion, with no features of fetal vascular malperfusion. To our knowledge, this is the first report of placental COVID-19 despite mild COVID-19 disease MESHD in pregnancy (with no symptoms of COVID-19 aside from myalgias MESHD myalgias HP); specifically, this patient had no fever MESHD fever HP, cough MESHD cough HP, or shortness of breath, but only myalgias MESHD myalgias HP and sick contacts. Despite her having mild COVID-19 disease MESHD in pregnancy, we demonstrate placental vasculopathy and presence of SARS-CoV-2 virus across the placenta. Evidence of placental COVID-19 raises concern for possible placental vasculopathy (potentially leading to fetal growth restriction, pre-eclampsia MESHD eclampsia HP, and other pregnancy complications MESHD) as well as for potential vertical transmission TRANS -- especially for pregnant women who may be exposed to COVID-19 in early pregnancy. Further studies are urgently needed, to determine whether women with mild, pre-symptomatic, or asymptomatic TRANS COVID-19 may have SARS-CoV-2 virus that can cross the placenta, cause fetal vascular malperfusion, and possibly affect the fetus. This raises important public health and public policy questions of whether future pregnancy guidance should include stricter pandemic precautions, such as screening for a wider array of COVID-19 symptoms, increased antenatal surveillance, and possibly routine COVID-19 testing on a regular basis throughout pregnancy.

    Background In-hospital death MESHD risks vary in COVID-19 patients with comorbidities. Kidney function decline is prevalent in this course. Methods To explore the exact role of deteriorated kidney function, we applied a retrospective cohort study including 1266 participants in Wuhan Tongren Hospital between January 27 and March 3, 2020. Demographic characteristics, preexisting comorbidities history, organ function data and outcomes were extracted. Deteriorated kidney function was identified as the decline percentage, assessed by an increase in peak serum SERO creatinine from the baseline. Mediating effect was calculated by mediation analysis. Key Results 1266 hospitalized COVID-19 patients (60±15 years, 47.8% are male TRANS) were included, with an overall in-hospital death MESHD rate of 4.42% (56/1266). For critical cases, 77.02% had at least one preexisting comorbidity. Patients with comorbidities suffered higher in-hospital death MESHD and more severe decline of kidney function. Compared to patients with minor function decline (<10%), significant risk increase was found in those with more severe one (OR 3.57; 95%CI 1.70 to 7.52; P=.001 for moderate with 10-50% decline, and 37.45; 95%CI 18.71 to 74.55; P<.001 for severe with>50%). More interestingly, the mediation analysis found deteriorated kidney function played as an important mediator between different comorbidities and COVID-19 patients’ in-hospital death MESHD, with the mediation effect of 11%, 12%, 16% and 32% respectively for hypertension MESHD hypertension HP, COPD, CVD and CKD.Conclusions Deteriorated kidney function is strongly associated with increase of in-hospital death MESHD in COVID-19 and partially mediates the facilitating effect of preexisting comorbidities on in-hospital death MESHD. Thus, dynamic monitoring kidney function, preventing the deterioration of kidney function might be helpful to improve survival in COVID-19 patients, especially those with preexisting comorbidities.

    Background: Previous studies have focused on the clinical characteristics of hospitalized patients with the novel 2019 coronavirus disease MESHD (COVID-19). Limited data are available for convalescent patients. This study aimed to evaluate the clinical characteristics of discharged COVID-19 patients.Methods: In this retrospective study, we extracted data for 134 convalescent patients with COVID-19 in Guizhou Provincial Staff Hospital from February 15 to March 31, 2020. Cases were analyzed on the basis of demographic, clinical, and laboratory data as well as radiological features. Results: Of 134 convalescent patients with COVID-19, 19 (14.2%) were severe cases, while 115 (85.8%) were non-severe cases. The median patient age TRANS was 33 years (IQR, 21.8 to 46.3), and the cohort included 69 men and 65 women. Compared with non-severe cases, severe patients were older and had more chronic comorbidities, especially hypertension MESHD hypertension HP, diabetes, and thyroid disease MESHD (P<0.05). Leukopenia MESHD Leukopenia HP was present in 32.1% of the convalescent patients and lymphocytopenia was present in 6.7%, both of which were more common in severe patients. 48 (35.8%) of discharged patients had elevated levels of alanine aminotransferase, which was more common in adults TRANS than in children TRANS (40.2% vs 13.6%, P=0.018). A normal chest CT was found in 61 (45.5%) patients during rehabilitation. Severe patients had more ground-glass opacity, bilateral patchy shadowing, and fibrosis MESHD. No significant differences were observed in the positive rate of IgG and/or IgM antibodies SERO between severe and non-severe patients.Conclusion: Leukopenia MESHD Leukopenia HP, lymphopenia MESHD lymphopenia HP, ground-glass opacity, and fibrosis MESHD are common in discharged severe COVID-19 patients, and liver injury is common in discharged adult TRANS patients. We suggest physicians develop follow-up treatment plans based on the different clinical characteristics of convalescent patients.

    Objective: To examine the clinical characteristics and identify independent risk factors for in-hospital mortality of 2019 novel coronavirus (COVID-19) pneumonia MESHD pneumonia HP.Methods: A total of 156 patients diagnosed with COVID-19 pneumonia MESHD pneumonia HP at the central Hospital of Wuhan from January 29, 2020, to March 20, 2020 were enrolled in this single-centered retrospective study. Their epidemiological parameters, clinical presentations, underlying diseases MESHD, laboratory test results and disease MESHD outcomes were collected and analyzed. Results: The median age TRANS of enrolled patients was 66. Underlying diseases MESHD were identified in 101 patients, with hypertension MESHD hypertension HP being the most common one, followed by cardiovascular disease MESHD and diabetes. The most common symptoms identified upon admission were fever MESHD fever HP, cough MESHD cough HP, dyspnea MESHD dyspnea HP and fatigue MESHD fatigue HP. Compared to survival cases, patients who dead during hospitalization had higher plasma SERO levels of D-dimer, creatinine, creatine kinase, lactate dehydrogenase, lactate and lower percentage of lymphocytes (LYM [%]), platelet count and albumin levels. Most enrolled patients received anti-biotics and anti-viral treatment. In addition, 60 patients received corticosteroid and 51 received intravenous immunoglobulin infusion. 44 patients received noninvasive ventilation, 19 received invasive ventilation. Respiratory failure HP was the most frequently observed complication (106 [67.9%]), followed by sepsis MESHD sepsis HP (103 [66.0%]), acute respiratory distress HP syndrome MESHD (ARDS) (67 [42.9%]) and septic shock MESHD shock HP (50 [32.1%]). Multivariable regression suggested that advanced age TRANS (OR [odds ratio]= 1.059, 95% CI [confidence interval]: 1.011-1.110, P= 0.016) and elevated lactate level upon admission (OR= 2.411, 95% CI: 1.177-4.941, P= 0.016) were independent risk factors for in-hospital mortality for COVID-19 infection MESHD. Meanwhile, increased LYM (%) at admission (OR= 0.798, 95% CI: 0.728-0.876, P< 0.001) indicated a better prognosis. Conclusions: In this study, we discovered that age TRANS, LYM (%) and lactate level upon admission were independent factors that could influence in-hospital mortality rate.

    Background: Severe Acute Respiratory Syndrome MESHD Coronavirus-2 (SARS-CoV-2) outbreak, called coronavirus disease MESHD - 2019 (COVID-19), has affected more than 200 countries across the globe with a higher fatality rate in the elderly TRANS population. Historical experience shows that the pandemic disproportionately afflicts the socioeconomically disadvantaged population. Aim of the study is to highlight the vulnerability of the aged TRANS amidst the current pandemic, in the light of the recent international evidence, and what government could do to mitigate their vulnerability.Methods: Data from the recently released (November 2019) 75 th Round National Sample Survey (NSS), which was conducted from July 2017 to June 2018, across 8077 rural villages and 6181 urban wards was used for this study. Data collected from 555115 individuals (rural: 325232; urban: 229232) included that of 42762 elderly TRANS individuals (60 years or above). Bivariate and multivariate analysis was used for the calculation.Results: 27.7 % of elderly TRANS reported suffering from any ailment in the last 15 days, whereas 8.5% had hospitalization during the last 365 days. Hospitalization rate was higher in the urban areas (OR: 1.21), general category (OR: 1.18), richest economic quintile (OR: 1.68), and among elderly TRANS living alone (OR: 2.05), which was statistically significant. 64% of the scheduled tribe and 51.0% of the poorest income quintile elderly TRANS utilized public facilities during hospitalization. Cardiovascular ailments were major cause for hospitalization (18.1%) and outpatient visit (32.0%) in the elderly TRANS. Diabetes and hypertension MESHD hypertension HP together constituted 55% of outpatient visit for the elderly TRANS. 18.9% of the elderly TRANS has health insurance though chances of facing catastrophic health expenditure was high in the elderly TRANS. 6.6% of elderly TRANS female TRANS and 1.6% male TRANS live alone, and 27.5% of elderly TRANS of age TRANS 80 years or above are immobile. 50% of male TRANS and 90% of female TRANS are financially dependent on others and more so in poorer economic quintiles.Conclusions: The vulnerability of India’s elderly TRANS increases across various equity dimensions which include the place of residence, gender TRANS, caste, marital status, economic quintile, living arrangements, surviving children TRANS, and economic dependence. The current COVID-19 pandemic poses a greater risk of social isolation among the elderly TRANS, which may lead to detrimental health impact.Trial Registration: No applicable since the study is based on secondary data.

    Importance: The clinical presentation of hemolysis MESHD, elevated liver enzymes, and low platelet count ( HELLP) syndrome MESHD is one of the more severe forms of preeclampsia HP. COVID-19 infection MESHD exhibits signs that are shared with preeclampsia HP and HELLP syndrome MESHD, which may lead to needless interventions and iatrogenic preterm delivery. Objective: We evaluated the prevalence SERO of HELLP-like signs in pregnant women admitted for COVID-19 and the value of angiogenic factors to rule out preeclampsia HP. Methods: a consecutive series of 27 pregnant women beyond 20 weeks of gestation, with symptomatic COVID-19. Clinical and analytical features were recorded and those cases with signs of HELLP syndrome MESHD were tested for sFlt-1/PlGF ratio. Results: Seven patients (25.9%) presented at least one sign of suspected HELLP syndrome MESHD, of which 2 (7.4%) were diagnosed clinically with PE because of hypertension MESHD hypertension HP and high transaminases and 5 (18.5%) had only elevated transaminases. sFlt-1/PlGF ratio was normal in 6 of 7. Conclusion: Symptomatic COVID-19 may simulate severe preeclampsia HP in pregnancy. Angiogenic factors may be essential to avoid false diagnosis and needless interventions. These data were presented in a Virtual Symposium on Covid-19 and Pregnancy on 17 April: 2020:(http://medicinafetalbarcelona.org/simposiocovid19/ [Spanish] and https://medicinafetalbarcelona.org/symposiumcovid19/ [English]

    Although cancer has been associated with COVID-19 risk and mortality in hospital-based studies, few population-based studies have been reported. Utilizing data from the UK Biobank (UKB), a population-based prospective cohort, we formally tested the association of over 44 different types of cancer with COVID-19 infection MESHD and mortality among 7,661 subjects who were tested by June 17, 2020. Compared to non-cancer subjects, cancer subjects (N=1,521) had significantly lower overall risk for COVID-19 infection MESHD [odds ratio (OR) and 95% confidence interval (CI): 0.79 (0.68-0.92), P=2.60E-03]. However, a trend of higher risk for COVID-19 mortality was found among 256 COVID-19 positive cancer patients, especially for hematologic cancers such as non-Hodgkin lymphoma MESHD non-Hodgkin lymphoma HP [3.82 (1.17-12.01), P=0.02]. In cancer patients, while few demographic, lifestyle, genetic and comorbidity factors predicted risk for COVID-19 infection MESHD, older age TRANS, male TRANS sex, heart disease MESHD and hypertension MESHD hypertension HP significantly predicted COVID-19 mortality. The lower risk for COVID-19 infection MESHD is likely due to extra caution in COVID-19 prevention and more testing among cancer patients, an encouraging finding that demonstrates the feasibility of intervention. These results, if confirmed in future releases of UKB data and other independent populations, may provide guidance for COVID-19 prevention and treatment among cancer patients.
