A growing body of research finds that in men, testosterone levels may be prognostic of clinical outcomes related to coronavirus disease 2019 (COVID-19 disease). The presence of pre-existing chronic conditions in many patients with COVID-19 disease further complicates the relationship among testosterone and severe outcomes. The aim of this study was to examine whether pre-existing conditions for severe COVID-19 disease were related to serum-free testosterone levels in men who had not been infected with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus. This study obtained data from men (n = 142) who participated in the longitudinal study Waco COVID Survey. All data included in the study was collected as part of the initial intake survey and first laboratory appointment. Results show that serum-free testosterone levels decreased as a function of age. In fact, greater burden of pre-existing conditions for severe COVID-19 disease was related to lower testosterone levels among men younger than 40 years of age. Furthermore, in men older than 40 years of age the decrease in testosterone that accompanies aging attenuated the effect of the clinical risk score on free testosterone levels. Authors conclude that their findings add important insights into the complex role of androgens in chronic and infectious diseases and contribute to the growing body of literature on the relationship between chronic disease and men’s testosterone levels.
Abstract
Testosterone levels in men appear to be prognostic of a number of disease outcomes, including severe COVID-19 disease. Testosterone levels naturally decline with age and are lower in individuals with a number of comorbidities and chronic conditions. Low testosterone may therefore be both a cause and a consequence of illness, including COVID-19 disease. The present project examines whether preexisting conditions for severe COVID-19 disease were themselves related to serum-free testosterone levels in men who had not been infected with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus. A clinical risk score for severe COVID-19 disease was computed based on the results of previously published meta-analyses and cohort studies, and relationships between this score and testosterone levels were tested in 142 men ages 19 to 82 years. Greater burden of preexisting conditions for severe COVID-19 disease was related to lower testosterone levels among men younger than 40 years of age. In older men, the decrease in testosterone that accompanies aging attenuated the effect of the clinical risk score on free testosterone levels. Given that older age itself is a predictor of COVID-19 disease severity, these results together suggest that the presence of preexisting conditions may confound the relationship between testosterone levels and COVID-19 disease outcomes in men. Future research examining relationships among testosterone and outcomes related to infectious and chronic diseases should consider potential confounds, such as the role of preexisting conditions.

Plain language summary
Salt imbalances in individuals with Covid-19 are highly prevalent, however it is not fully understood if they determine whether a patient has a good or bad prognosis. This systematic review and meta-analysis of 28 observational studies aimed to determine the associations and prognostic value of different salt imbalances in individuals with Covid-19. The results showed that out of several salt imbalances analysed, high and low sodium levels and low calcium levels could predict poor outcomes in those with Covid-19. High sodium levels were particularly indicative, but this was not due to the relationship between high sodium and inflammation in the body and causal reasons remained undiscovered. It was concluded that sodium imbalances and low calcium levels were associated with poor clinical outcomes in individuals with Covid-19. This study could be used by healthcare professionals to understand that correcting these imbalances may be of benefit to individuals with Covid-19.
Abstract
PURPOSE Serum electrolyte imbalances are highly prevalent in COVID-19 patients. However, their associations with COVID-19 outcomes are inconsistent, and of unknown prognostic value. We aim to systematically clarify the associations and prognostic accuracy of electrolyte imbalances (sodium, calcium, potassium, magnesium, chloride and phosphate) in predicting poor COVID-19 clinical outcome. METHODS PubMed, Embase and Cochrane Library were searched. Odds of poor clinical outcome (a composite of mortality, intensive-care unit (ICU) admission, need for respiratory support and acute respiratory distress syndrome) were pooled using mixed-effects models. The associated prognostic sensitivity, positive and negative likelihood ratios (LR + , LR-) and predictive values (PPV, NPV; assuming 25% pre-test probability), and area under the curve (AUC) were computed. RESULTS We included 28 observational studies from 953 records with low to moderate risk-of-bias. Hyponatremia (OR = 2.08, 95% CI = 1.48-2.94, I2 = 93%, N = 8), hypernatremia (OR = 4.32, 95% CI = 3.17-5.88, I2 = 45%, N = 7) and hypocalcemia (OR = 3.31, 95% CI = 2.24-4.88, I2 = 25%, N = 6) were associated with poor COVID-19 outcome. These associations remained significant on adjustment for covariates such as demographics and comorbidities. Hypernatremia was 97% specific in predicting poor outcome (LR + 4.0, PPV = 55%, AUC = 0.80) despite no differences in CRP and IL-6 levels between hypernatremic and normonatremic patients. Hypocalcemia was 76% sensitive in predicting poor outcome (LR- 0.44, NPV = 87%, AUC = 0.71). Overall quality of evidence ranged from very low to moderate. CONCLUSION Hyponatremia, hypernatremia and hypocalcemia are associated with poor COVID-19 clinical outcome. Hypernatremia is 97% specific for a poor outcome, and the association is independent of inflammatory marker levels. Further studies should evaluate if correcting these imbalances help improve clinical outcome.

Abstract
Dietary quality and patterns may influence SARS-CoV-2 infection and outcomes, but scientific data and evidence to support such a role are lacking. Therefore, this meta-analysis aims to elucidate the effect of prepandemic diet quality on the risk of COVID-19 infection and hospitalization. PubMed/MEDLINE, CENTRAL, Scopus, and EMBASE were systematically searched for articles published up to September 1, 2022. A systematic review and meta-analysis were performed to calculate each outcome's risk ratio (RR) and 95% confidence interval (CI). Five studies including 4 023 663 individuals (3 149 784 high-quality diet individuals and 873 881 controls) were included in the present meta-analysis. The effectiveness of high-quality dietary pattern against SARS-CoV-2 infection and hospitalization was 28% (95% CI 19%-36%) and 62% (95% CI 25%-80%); respectively. Subgroup analysis based on different levels of diet quality showed no difference between middle and high levels of diet quality in reducing the risk of COVID-19 infection. Interestingly, subgroup analysis based on the different types of high-quality diets and the risk of COVID-19 infection revealed that the effectiveness of plant-based diet against SARS-CoV-2 infection was 50% (95% CI 30%-65%); while the effectiveness of Mediterranean diet against SARS-CoV-2 infection was 22% (95% CI 12%-31%). Adherence to a high-quality dietary pattern is associated with a lower risk of COVID-19 infection and hospitalization. More studies are required to confirm these findings, and future studies should determine the biological mechanisms underlying the association between diet quality and risk of COVID-19 infection.

Abstract
AIM: To provide a detailled analysis of the microvascular burden in patients with diabetes hopitalized for COVD-19. MATERIALS AND METHODS We analysed data from the French CORONADO initiative and the UK Association of British Clinical Diabetologists (ABCD) COVID-19 audit, two nationwide multicentre studies, and the AMERICADO, a multicentre study conducted in New York area. We assessed the association between risk of all-cause death during hospital stay and the following microvascular complications in patients with diabetes hospitalized for COVID-19: diabetic retinopathy and/or diabetic kidney disease and/or history of diabetic foot ulcer. RESULTS Among 2951 CORONADO, 3387 ABCD COVID-19 audit and 9327 AMERICADO participants, microvascular diabetic complications status was ascertained for 1314 (44.5%), 1809 (53.4%) and 7367 (79.0%) patients, respectively: 1010, 1059 and 1800, respectively, had ≥1 severe microvascular complication(s) and 304, 750 and 5567, respectively, were free of any complications. The patients with isolated diabetic kidney disease had an increased risk of all-cause death during hospital stay: odds ratio [OR] 2.53 (95% confidence interval [CI] 1.66-3.83), OR 1.24 (95% CI 1.00-1.56) and OR 1.66 (95% CI 1.40-1.95) in the CORONADO, the ABCD COVID-19 national audit and the AMERICADO studies, respectively. After adjustment for age, sex, hypertension and cardiovascular disease (CVD), compared to those without microvascular complications, patients with microvascular complications had an increased risk of all-cause death during hospital stay in the CORONADO, the ABCD COVID-19 diabetes national audit and the AMERICADO studies: adjusted OR (adj OR) 2.57 (95% CI 1.69-3.92), adj OR 1.22 (95% CI 1.00-1.52) and adj OR 1.33 (95% CI 1.15-1.53), respectively. In meta-analysis of the three studies, compared to patients free of complications, those with microvascular complications had an unadjusted OR for all-cause death during hospital stay of 2.05 (95% CI 1.42-2.97), which decreased to 1.62 (95% CI 1.19-2.119) after adjustment for age and sex, and to 1.50 (1.12-2.02) after hypertension and CVD were further added to the model. CONCLUSION Microvascular burden is associated with an increased risk of death in patients hospitalized for COVID-19.

Abstract
BACKGROUND Randomized controlled trials (RCT) established the mortality reduction by tocilizumab (Actemra), baricitinib (Olumiant), and sarilumab (Kevzara) in hospitalized COVID-19 patients. However, uncertainty remains about which treatment performs best in patients receiving corticosteroids. OBJECTIVES To estimate probabilities of noninferiority between baricitinib and sarilumab compared to tocilizumab in patients treated with corticosteroids. DATA SOURCES PubMed, Embase, Cochrane Library, and MedRxiv. STUDY ELIGIBILITY CRITERIA Eligible RCTs assigning hospitalized adults with COVID-19 treated with corticosteroids to tocilizumab or baricitinib or sarilumab versus standard of care or placebo (control). METHODS Reviewers independently abstracted published data and assessed study quality with the Risk of Bias 2 tool. Unpublished data, if required, were requested from authors of included studies. The outcome of interest was all-cause mortality at 28 days. PARTICIPANTS Twenty-seven RCTs with 13 549 patients were included. Overall, the risk of bias was low. Bayesian pairwise meta-analyses were used to aggregate results of each treatment versus control. The average odds ratio for mortality was 0.78 (95% credible interval [CrI]: 0.65, 0.94) for tocilizumab; 0.78 (95% CrI: 0.56, 1.03) for baricitinib; and 0.91 (95% CrI: 0.60, 1.40) for sarilumab. The certainty of evidence (GRADE) ranged from moderate to low. Bayesian meta-regressions with multiple priors were used to estimate probabilities of noninferiority (margin of 13% greater effect by tocilizumab). Compared to tocilizumab, there were ≤94% and 90% probabilities of noninferiority with baricitinib and sarilumab, respectively. RESULTS All but two studies included data with only indirect evidence for the comparison of interest. CONCLUSIONS Among hospitalized COVID-19 treated with corticosteroids, there are high probabilities that both baricitinib and sarilumab are associated with similar mortality reductions in comparison to tocilizumab.

Abstract
BACKGROUND Diabetic ketoacidosis (DKA) is a potentially life-threatening complication of type 1 diabetes mellitus (T1DM) that has increased during the COVID-19 pandemic. This study will not only shed light on such life-threatening complications but also be a step to increase the awareness of healthcare providers about such complications in the upcoming pandemic waves and increased dependence on telemedicine. Thus, we aimed to further investigate the increase of DKA in pediatrics. METHODS PubMed, Web of Science, and Scopus were broadly searched for studies assessing the incidence of DKA in pediatrics during the COVID-19 pandemic. RESULTS Our study included 24 papers with a total of 124,597 children with diabetes. A statistically significant increase occurred in the risk of DKA among newly diagnosed T1DM patients during the pandemic (RR 1.41; 95% CI 1.19, 1.67; p < 0.01; I2 = 86%), especially in the severe form of DKA (RR 1.66: 95% CI 1.3, 2.11) when compared to before. CONCLUSION DKA in newly diagnosed children with T1DM has increased during the pandemic and presented with a severe form. This may reflect that COVID-19 may have contributed not only to the development but also the severity of DKA. IMPACT Diabetic ketoacidosis (DKA) is a life-threatening complication of type 1 diabetes mellitus (T1DM) that has increased during the COVID-19 pandemic. Our study included 25 papers with a total of 124,597 children with diabetes. A statistically significant increase occurred in the risk of DKA among newly diagnosed T1DM patients during the pandemic. Our findings reflect that COVID-19 may have an altered presentation in T1DM and can be related to DKA severity.

Abstract
AIMS: This study aims to examine the effectiveness of using sodium glucose transporter-2 inhibitor (SGLT-2i) before hospital admission on Covid-19 outcomes in diabetic patients. METHODS A literature search was conducted using specific keywords until October 24th, 2022 on 4 databases: Medline, Scopus, Cochrane Library, and ClinicalTrials.gov. All articles regarding SGLT-2i in diabetic patients with Covid-19 were included in the study. Outcomes in this study were calculated using random-effect models to generate pooled odds ratio (OR) with 95% confidence intervals (CI). RESULTS A total of 17 studies were included in the analysis. Our meta-analysis showed that pre-admission use of SGLT-2i was associated with reduced mortality (OR 0.69; 95 %CI: 0.56 - 0.87, p = 0.001, I2 = 91 %) and severity of Covid-19 (OR 0.88; 95 %CI: 0.80 - 0.97, p = 0.008, I2 = 13 %). This benefit of SGLT-2i on Covid-19 mortality was not significantly affected by patient's factors such as age (p = 0.2335), sex (p = 0.2742), hypertension (p = 0.2165), heart failure (p = 0.1616), HbA1c levels (p = 0.4924), metformin use (p = 0.6617), duration of diabetes (p = 0.7233), and BMI (p = 0.1797). CONCLUSIONS This study suggests that SGLT-2i as glucose lowering treatment in patients with diabetes has a positive effect on Covid-19 outcomes, therefore can be considered as an antidiabetic drug of choice, especially during the Covid-19 pandemic.

Abstract
Coronavirus disease 2019 (COVID-19) has become a global epidemic, and there is no specific treatment for anti-COVID-19 drugs. However, treatment of COVID-19 using Chinese herbal medicine (CHM) has been widely practiced in China. PubMed, Embase, Cochrane Library, CNKI, Wanfang and VIP databases were searched to evaluate the efficacy and safety of CHM in the treatment of COVID-19. Twenty-six studies were included in this meta-analysis. The included cases were all patients diagnosed with COVID-19 according to the "New Coronary Virus Pneumonia Diagnosis and Treatment Program," with a total of 2,407 cases. Patients were treated with CHM, including 36 prescriptions, and 105 flavors of CHM were included. The results of the meta-analysis showed that the CHM group improved in lung CT, clinical cure rate, clinical symptom score and time to negative for viral nucleic acid. However, this study still has many limitations due to the limited number of included studies. Therefore, high-quality RCT studies are needed to provide more reliable evidence for CHM treatment of COVID-19. In conclusion, CHM may significantly improve the clinical manifestations and laboratory indicators of patients with COVID-19. In addition, no serious adverse reactions were found after CHM treatment. Therefore, CHM may be used as a potential candidate for COVID-19. HIGHLIGHTS COVID-19 has become a global epidemic, and there is no specific treatment for anti-COVID-19 drugs. CHM has made a new breakthrough in the treatment of COVID-19. CHM may relieve lung CT images of COVID-19 patients. CHM may improve clinical symptoms of COVID-19 patients. CHM may inhibit the expression of inflammatory factors in patients with COVID-19.
