    The consequences of wearing biosafety equipment by healthcare professionals during their work and the prediction of such consequences need to be assessed. To analyze the role played by different blood SERO biomarkers in predicting the appearance of headaches MESHD headaches HP in healthcare workers wearing personal protective equipment (PPE) in a COVID-19 treatment unit, a Prospective cohort study of 38 healthcare workers from a convalescence MESHD unit of patients with COVID-19 in a field hospital was performed during April 2020. Blood SERO analysis was carried out before the start of the 4 hours shift of the volunteers equipped with PPE. After decontamination, there were asked if they had suffered from headache MESHD headache HP, obtaining the binary outcome. This study included 38 participants with a median age TRANS of 29 years (25th-75th percentile: 26-44 years old), 73.7% female TRANS (28 cases). 44.7% (17 cases) had a headache MESHD headache HP after wearing PPE for 4 hours. The baseline creatinine value reflected a specific odds ratio in the regression model of 241.36 (95% CI: 2.50-23,295.43; p=0.019), and an AUC of 0.737 (95%CI: 0.57-0.90; p<0.01). Blood SERO creatinine is a good candidate for predicting the appearance of a de novo headache MESHD headache HP in healthcare workers after wearing PPE for 4 hours in a COVID – 19 unit.

    Gastrointestinal (GI) symptoms of SARS-CoV2/COVID-19 in the form of anorexia MESHD anorexia HP, nausea MESHD nausea, vomiting HP, vomiting MESHD, abdominal pain MESHD abdominal pain HP and diarrhea MESHD diarrhea HP are usually preceeded by respiratory manifestations and are associated with a poor prognosis. Hematochezia HP is an uncommon clinical presentation of COVID-19 disease MESHD and we hypothesize that older patients with significant comorbidites ( obesity MESHD obesity HP and cardiovascular) and prolonged hospitalization are suspectible to ischemic injury to the bowel. We reviewed the clinical course, key laboratory data including acute phase reactants, drug/medication history in two elderly TRANS male TRANS patients admitted for COVID-19 respiratory failure HP. Both patients had a complicated clinical course and suffered from hematochezia HP and acute blood SERO loss anemia MESHD anemia HP requiring blood SERO transfusion around day 40 of their hospitalization. Colonoscopic impressions were correlated with the histopathological findings in the colonic biopies and changes compatible with ischemia MESHD to nonspecific acute inflammation MESHD, edema MESHD edema HP and increased eosinophils in the lamina propria were noted.Both patients were on anticoagulants, multiple antibiotics and antifungal agents due to respiratory infections MESHD at the time of lower GI bleeding. Hematochezia HP resolved spontaneously with supportive care. Both patients eventually recovered and were discharged. Elderly TRANS patients with significant comorbid conditions are uniquely at risk for ischemic injury to the bowel. Hypoxic conditions due to COVID-19 pneumonia MESHD pneumonia HP and respiratory failure HP, compounded by preexisting cardiovascular complications, and/or cytokine storm orchestrated by the viral infection MESHD leading to alteration in coagulation profile and/or drug/medication injury can be difficult to distinguish in these critically ill patients. Presentation of hematochezia HP may further increase the mortality and morbidity of COVID-19 patients, and prompt consultation and management by gastroenterology is therefore warranted.

    Background: There is a paucity of data on the management of gastrointestinal(GI) bleeding in patients with COVID-19 amid concerns about the risk of transmission TRANS during endoscopic procedures.We aimed to study the outcomes of conservative treatment for GI bleeding in patients with COVID-19. Methods: In this retrospective analysis, 24 of 1342(1.8%) patients with COVID-19, presenting with GI bleeding from 22ndApril to 22ndJuly 2020, were included. Results: The mean age TRANS of patients was 45.8+/-12.7 years; 17(70.8%) were males TRANS; upper GI(UGI) bleeding: lower GI(LGI) 23:1. Twenty-two(91.6%) patients had evidence of cirrhosis HP- 21 presented with UGI bleeding while one had bleeding from hemorrhoids MESHD hemorrhoids HP. Two patients without cirrhosis HP were presumed to have non-variceal bleeding. The medical therapy for UGI bleeding included vasoconstrictors- somatostatin in 17(73.9%) and terlipressin in 4(17.4%) patients. All patients with UGI bleeding received proton pump inhibitors and antibiotics. Packed red blood SERO cells(PRBCs), fresh frozen plasma SERO and platelets were transfused in 14(60.9%), 3(13.0%) and 3(13.0%), respectively. The median PRBCs transfused was 1(0-3) unit(s). The initial control of UGI bleeding was achieved in all 23 patients and none required an emergency MESHD endoscopy. At 5-day follow-up, none rebled or died. Two patients later rebled, one had intermittent bleed due to gastric antral vascular ectasia MESHD, while another had rebleed 19 days after discharge. Three(12.5%) cirrhosis HP patients succumbed to acute hypoxemic respiratory failure HP during hospital stay. Conclusion: Conservative management strategies including pharmacotherapy, restrictive transfusion strategy, and close hemodynamic monitoring can successfully manage GI bleeding in COVID-19 patients and reduce need for urgent endoscopy.

    Coronavirus Disease MESHD 2019 (COVID-19) Pandemic is ongoing, and to know how far the virus has spread in Niger State, Nigeria, a pilot study was carried out to determine the COVID-19 seroprevalence SERO, patterns, dynamics, and risk factors in the state. A cross sectional study design and clustered-stratified-Random sampling strategy were used. COVID-19 IgG and IgM Rapid Test SERO Kits (Colloidal gold immunochromatography lateral flow system) were used to determine the presence or absence of antibodies to SARS-CoV-2 SERO in the blood SERO of sampled participants across Niger State as from 26th June 2020 to 30th June 2020. The test kits were validated using the blood SERO samples of some of the NCDC confirmed positive and negative COVID-19 cases in the State. COVID-19 IgG and IgM Test results were entered into the EPIINFO questionnaire administered simultaneously with each test. EPIINFO was then used for both the descriptive and inferential statistical analyses of the data generated. The seroprevalence SERO of COVID-19 in Niger State was found to be 25.41% and 2.16% for the positive IgG and IgM respectively. Seroprevalence SERO among age groups TRANS, gender TRANS and by occupation varied widely. A seroprevalence SERO of 37.21% was recorded among health care workers in Niger State. Among age groups TRANS, COVID-19 seroprevalence SERO was found to be in order of 30-41 years (33.33%) > 42-53 years (32.42%) > 54-65 years (30%) > 66 years and above (25%) > 6-17 years (19.20%) > 18-29 years (17.65%) > 5 years and below (6.66%). A seroprevalence SERO of 27.18% was recorded for males TRANS and 23.17% for females TRANS in the state. COVID-19 asymptomatic TRANS rate in the state was found to be 46.81%. The risk analyses showed that the chances of infection MESHD are almost the same for both urban and rural dwellers in the state. However, health care workers and those that have had contact with person (s) that travelled TRANS out of Nigeria in the last six (6) months are twice ( 2 times) at risk of being infected with the virus. More than half (54.59%) of the participants in this study did not practice social distancing at any time since the pandemic started. Discussions about knowledge, practice and attitude of the participants are included. The observed Niger State COVID-19 seroprevalence SERO means that the herd immunity for COVID-19 is yet to be achieved and the population is still susceptible for more infection MESHD and transmission TRANS of the virus. If the prevalence SERO stays as reported here, the population will definitely need COVID-19 vaccines when they become available. Niger State should fully enforce the use of face/nose masks and observation of social/physical distancing in gatherings including religious gatherings in order to stop or slow the spread of the virus.

    Objective: To identify sex-specific effects of risk factors for in-hospital mortality among COVID-19 patients admitted to a hospital system in New York City. Design: Prospective observational cohort study with in-hospital mortality as the primary outcome. Setting: Five acute care hospitals within a single academic medical system in New York City. Participants: 3,086 hospital inpatients with COVID-19 admitted on or before April 13, 2020 and followed through June 2, 2020. Follow-up till discharge or death MESHD was complete for 99.3% of the cohort. Results: The majority of the cohort was male TRANS (59.6%). Men were younger (median 64 vs. 70, p<0.001) and less likely to have comorbidities such as hypertension MESHD hypertension HP (32.5% vs. 39.9%, p<0.001), diabetes (22.6% vs. 26%, p=0.03), and obesity MESHD obesity HP (6.9% vs. 9.8%, p=0.004) compared to women. Women had lower median values of laboratory markers associated with inflammation MESHD compared to men: white blood SERO cells (5.95 vs. 6.8 K/uL, p<0.001), procalcitonin (0.14 vs 0.21 ng/mL, p<0.001), lactate dehydrogenase (375 vs. 428 U/L, p<0.001), C-reactive protein (87.7 vs. 123.2 mg/L, p<0.001). Unadjusted mortality was similar between men and women (28.8% vs. 28.5%, p=0.84), but more men required intensive care than women (25.2% vs. 19%, p<0.001). Male TRANS sex was an independent risk factor for mortality (OR 1.26, 95% 1.04-1.51) after adjustment for demographics, comorbidities, and baseline hypoxia MESHD. There were significant interactions between sex and coronary artery disease MESHD (p=0.038), obesity MESHD obesity HP (p=0.01), baseline hypoxia MESHD (p<0.001), ferritin (p=0.002), lactate dehydrogenase (p=0.003), and procalcitonin (p=0.03). Except for procalcitonin, which had the opposite association, each of these factors was associated with disproportionately higher mortality among women. Conclusions: Male TRANS sex was an independent predictor of mortality, consistent with prior studies. Notably, there were significant sex-specific interactions which indicated a disproportionate increase in mortality among women with coronary artery disease MESHD, obesity MESHD obesity HP, and hypoxia MESHD. These new findings highlight patient subgroups for further study and help explain the recognized sex differences in COVID-19 outcomes.

    Objectives: Coronavirus disease MESHD 2019 (COVID-19) can present with a variety of symptoms. Severity of the disease MESHD may be associated with several factors. Here, we review clinical features of COVID-19 patients with different severities.Methods: This cross-sectional study was performed in Imam Reza hospital, Mashhad, Iran, during February-April 2020. COVID-19 patients with typical computed tomography (CT) patterns and/or positive reverse-transcriptase polymerase chain reaction (RT-PCR) were included. The patients were classified into three groups of moderate, severe, and critical based on disease MESHD severity. Demographic, clinical, laboratory, and radiologic findings were collected and compared. P<0.05 was considered statistically significant.Results: Overall, 200 patients with mean age TRANS of 69.75±6.39 years, of whom 82 (41%) were female TRANS were studied. Disease MESHD was severe/critical in the majority of patients (167, 83.5%). Disease MESHD severity was significantly associated with age TRANS, malignant comorbidities, dyspnea MESHD dyspnea HP, nausea MESHD nausea/vomiting HP/ vomiting MESHD, confusion MESHD confusion HP, respiratory rate, pulse rate, O2 saturation, extent of CT involvement, serum SERO C-reactive protein (CRP), pH, pO2, and aspartate transaminase (P<0.05). Moreover, complications including shock MESHD shock HP, coagulopathy, acidosis MESHD acidosis HP, sepsis MESHD sepsis HP, acute respiratory distress HP syndrome MESHD (ARDS), intensive care unit (ICU) admission, and intubation were significantly higher in patients with higher severities. O2 saturation, nausea MESHD nausea/vomiting HP/ vomiting MESHD, and extent of lung CT involvement were independent predictors of severe/critical COVID-19 (OR=0.342, 45.93, and 25.48, respectively; P<0.05).Conclusions: Our results indicate O2 saturation, nausea MESHD nausea/vomiting HP/ vomiting MESHD, and extent of lung CT involvement as independent predictors of severe COVID-19 conditions. Serum SERO CRP levels and pO2 were also considerably higher patients with higher severity and can be used along with other factors as possible predictors of severe disease MESHD in COVID-19 patients.

    Background Pakistan is among the first low- and middle-income countries affected by COVID-19 pandemic. Monitoring progress through serial sero-surveys SERO, particularly at household level, in densely populated urban communities can provide insights in areas where testing is non-uniform. Methods Two serial cross-sectional household surveys were performed in April (phase 1) and June (phase 2) 2020 each in a low- (District Malir) and high- transmission TRANS (District East) area of Karachi, Pakistan. Household were selected using simple random sampling (Malir) and systematic random sampling (East). Individual participation rate from consented households was 82.3% (1000/1215 eligible) in phase 1 and 76.5% (1004/1312 eligible) in phase 2. All household members or their legal guardians answered questions related to symptoms of Covid-19 and provided blood SERO for testing with commercial Elecsys Anti-SARS-CoV-2 immunoassay SERO targeting combined IgG and IgM. Seroprevalence SERO estimates were computed for each area and time point independently. Given correlation among household seropositivity values, a Bayesian regression model accounting for household membership, age TRANS and gender TRANS was used to estimate seroprevalence SERO. These estimates by age TRANS and gender TRANS were then post-stratified to adjust for the demographic makeup of the respective district. The household conditional risk of infection TRANS risk of infection TRANS infection MESHD was estimated for each district and its confidence interval were obtained using a non-parametric bootstrap of households. Findings Post-stratified seroprevalence SERO was estimated to be 0.2% (95% CI 0-0.7) in low-and 0.4% (95% CI 0 - 1.3) in high- transmission TRANS areas in phase 1 and 8.7% (95% CI 5.1-13.1) in low- and 15.1% (95% CI 9.4 -21.7) in high- transmission TRANS areas in phase 2, with no consistent patterns between prevalence SERO rates for males TRANS and females TRANS. Conditional risk of infection TRANS risk of infection TRANS infection MESHD estimates (possible only for phase 2) were 0.31 (95% CI 0.16-0.47) in low- and 0.41(95% CI 0.28-0.52) in high- transmission TRANS areas. Of the 166 participants who tested positive, only 9(5.4%) gave a history of any symptoms. Interpretation A large increase in seroprevalence SERO to SARS-CoV-2 infection MESHD is seen, even in areas where transmission TRANS is reported to be low. Mostly the population is still seronegative. A large majority of seropositives do not report any symptoms. The probability that an individual in a household is infected, given that another household member is infected is high in both the areas. These results emphasise the need to enhance surveillance activities of COVID-19 especially in low- transmission TRANS sites and provide insights to risks of household transmission TRANS in tightly knit neighbourhoods in urban LMIC settings.

    Purpose: to evaluate the prognostic value of male TRANS serum SERO total testosterone (TT) levels among COVID-19 patients requiring an invasive respiratory assistance at hospital admission.Methods: 29 men with full haemato-chemical blood SERO sample panel at hospital admission for COVID-19 related respiratory syndrome MESHD were retrospectively reviewed. Multivariable logistic regression model was implemented to test the predictive role of TT levels and subsequent risk for invasive oxygenation after adjusting for age TRANS, comorbidities and life-style related confounders.  Results: higher serum SERO TT levels (ng/mL) were found independently associated with a lower odd of invasive oxygenation (Odds ratio [OR]: 0.43, 95%CI: 0.23-0.85; p=0.016). Significant negative correlation was found between TT and C-reactive protein, pH, Interleukine-6 and D-Dimer while positive correlation was established among TT levels and Monocytes (x109/L).Conclusion: low testosterone levels may play a relevant role in the natural history of COVID-19 respiratory syndrome MESHD by making a patient with comorbidities and higher baseline levels of pro-inflammatory cytokines more susceptible to a potentially fatal clinical course at the moment of infection MESHD progression.

    Background: The 2019 coronavirus disease MESHD (COVID-19) has become an unprecedented public health crisis with nearly 16 million confirmed cases TRANS and 630,000 deaths MESHD worldwide. Methods: We retrospectively investigated the demographic, clinical, laboratory, radiological and treatment data of COVID-19 patients consecutively enrolled from January 18 to May 15, 2020, in Taihe and Jinzhou central hospital. Results: Of all 197 patients, the median age TRANS was 66.5 years (IQR 7-76), and 120 (60.9%) patients were males TRANS. We identified 88 (44.7%) of 197 COVID-19 patients as the disease progression MESHD (aggravation) cases. The aggravation cases tend to have more medical comorbidity: hypertension MESHD hypertension HP (34.1%), diabetes (30.7%), and presented with dyspnea MESHD dyspnea HP (34.1%), neutrophilia HP (60.2%), and lymphocytopenia (73.9%), compared with those without. And the patients with disease progression MESHD showed significantly higher level of Fibrinogen (Fbg), D-dimer, IL-6, C-reactive protein (CRP), procalcitonin (PCT), and serum SERO ferritin, and were more prone to develop organ damage in the liver, kidney, and heart (P<0.05). Multivariable regression showed that advanced age TRANS, comorbidities, lymphopenia MESHD lymphopenia HP, and elevated level of Fbg, lactate dehydrogenase (LDH), Cardiac troponin (CTnI), IL-6, serum SERO ferritin were the significant predictors of disease progression MESHD. Further, we investigated antibody SERO responses to SARS-CoV-2 and found that the levels of IgM and IgG were significantly higher in the disease progression MESHD cases compared to non-progression cases from 3 weeks after symptom onset TRANS. In addition, the disease progression MESHD group tended to peak later and has a more vigorous IgM/IgG response against SARS-CoV-2. Further, we performed Kaplan-Meier analysis and found that 61.6% of patients had not experienced ICU transfer or survival from hospital within 25 days from admission.Conclusions: Investigating the potential factors of advanced age TRANS, comorbidities and elevated level of IL-6, serum SERO ferritin and Kaplan-Meier analysis enables early identification and management of patients with poor prognosis. Detection of the dynamic antibody SERO may offer vital clinical information during the course of SARS-CoV-2 and provide prognostic value for patients infection MESHD.

    Background There are no data on SARS-CoV-2 seroprevalence SERO in Africa though the COVID-19 epidemic curve and reported mortality differ from patterns seen elsewhere. We estimated the anti- SARS-CoV-2 antibody SERO prevalence SERO among blood SERO donors in Kenya. Methods We measured anti-SARS-CoV-2 spike IgG prevalence SERO by ELISA SERO on residual blood SERO donor samples obtained between April 30 and June 16, 2020. Assay sensitivity SERO and specificity were 83% (95% CI 59, 96%) and 99.0% (95% CI 98.1, 99.5%), respectively. National seroprevalence SERO was estimated using Bayesian multilevel regression and post-stratification to account for non-random sampling with respect to age TRANS, sex and region, adjusted for assay performance SERO. Results Complete data were available for 3098 of 3174 donors, aged TRANS 15-64 years. By comparison with the Kenyan population, the sample over-represented males TRANS (82% versus 49%), adults TRANS aged TRANS 25-34 years (40% versus 27%) and residents of coastal Counties (49% versus 9%). Crude overall seroprevalence SERO was 5.6% (174/3098). Population-weighted, test-adjusted national seroprevalence SERO was 5.2% (95% CI 3.7, 7.1%). Seroprevalence SERO was highest in the 3 largest urban Counties; Mombasa (9.3% [95% CI 6.4, 13.2%)], Nairobi (8.5% [95% CI 4.9, 13.5%]) and Kisumu (6.5% [95% CI 3.3, 11.2%]). Conclusions We estimate that 1 in 20 adults TRANS in Kenya had SARS-CoV-2 antibodies SERO during the study period. By the median date of our survey, only 2093 COVID-19 cases and 71 deaths MESHD had been reported through the national screening system. This contrasts, by several orders of magnitude, with the numbers of cases and deaths MESHD reported in parts of Europe and America when seroprevalence SERO was similar.
