ABSTRACT

Background: Mortality associated with COVID-19 varies in various reports, with minimal data on the factors associated with in-hospital mortality. Objective: To identify the risk factors for in-hospital death of patients with COVID-19 in an intensive care unit (ICU) in Qatar. Methods: A retrospective observational study of patients confirmed with COVID-19 and admitted to the medical-surgical ICU at The Cuban Hospital was carried out from April 12, 2020, to September 12, 2020. From patients' electronic medical records, demographic, clinical, laboratory, and radiology data was collected. Results: 275 patients with COVID-19 were admitted to the ICU, and 32 (11.6%) died. 56.1% were men, and the mean age was 52.2 years. According to the univariate analysis, patients with diabetes mellitus with end-organ damage (37.5%), cardiovascular disease (31.3%), dementia (9.4%), kidney disease (28.1%), chronic obstructive pulmonary disease (31.3%), and higher Charlson index had higher mortality. According to the multivariate analysis, an increase of mortality risk by 9% was observed for each additional year of age (Odds ratio [OR] 1.09;95% confidence interval [CI] 1.04-1.14), patients on mechanical ventilation (OR 27.33;95% CI 3.21-232.46), and those with adult respiratory distress (OR 15.85;95% CI 1.45-172.82) and elevated procalcitonin (OR 7.30;95% CI 1.25-42.58), and the PiO2/FiO2 ratio between 100 and 299 decreased the risk of death by 92% (OR 0.08;95% CI 0.02-0.39), in comparison to a PiO2/FiO2 ratio less than 100 or greater than 300. Conclusion: The study provides evidence about the risk of mortality among COVID-19 patients with a significant contribution of age, respiratory failure, and co-infections.

ABSTRACT

Objectives: Blood pressure variability (BPV) plays an important role in hypertensive patients, and frequently associated with organ damage. Although hypertension is the most common comorbidity in COVID-19, the impact of BPV and therapeutic target of BPV to outcome in COVID-19 patients with hypertension remain unclear. The aim of this study is to investigate the relationship between BPV and severity of COVID-19, in-hospital mortality, hypertensive status,, and efficacy of antihypertensives in suppress hypertensive covid-19 patient's BPV. Design and method: This was a cohort retrospective study that enrolled 351 patients hospitalized with COVID-19. Subjects were classified according to the presence of hypertension, the severity of COVID-19, and BPV status. Mean Arterial Pressure (MAP) was measured at 6 a.m. and 6 p.m. during hospitalization, and BPV was calculated as the coefficient of variation of MAP (MAPCV). MAPCV values above the median were defined as high BPV. We compared the hypertensive status, COVID-19 severity, in-hospital mortality and antihypertensive agents between the BPV groups. Results: The mean age was 53.85 ± 18.84 years-old. Subjects with high BPV were significantly associated with hypertension status (PR = 1.38;95%CI = 1.13- 1.70;p = 0.003) or severe COVID-19 (PR = 1.39;95%CI = 1.09-1.76;p = 0.005). In laboratory findings, high BPV group had higher CRP (55.15 ± 50.80 vs 97.79 ± 77.17), higher creatinine cerum (1.80 ± 3.15 vs 0.91 ± 0.14) and high BPV status also significantly increased risk of mortality (HR = 2.30;95%CI = 1.73-3,86;p = <0.001). Patients with combination of severe COVID-19 status, hypertension (+) and high BPV status had the highest risk of in-hospital mortality (HR = 3.51;95%CI = 2.32-4,97;p < 0.001) compared to other combination status of groups. In COVID-19 patients with hypertension, combination teraphy with CCB as well as CCB monoteraphy significantly decreased BPV (PR = 0.50;95%CI = 0.27-0.93;p = 0.004) and mortality (HR = 0.17;95%CI = 0.05-0.56;p = 0.004). Conclusions: High BPV was associated with hypertensive status and severe COVID-19, and these factors together increased in-hospital mortality. CCB are antihypertensive agents that were potentially effective in suppressing BPV and mortality in COVID-19 patients.

ABSTRACT

Objective: To study the association of calcium channel blockers (CCBs), the renin-angiotensin-aldosterone system (RAAS) inhibitors or their combination as antihypertensive medications and the clinical outcome of COVID-19 infection. Design and method: This is a retrospective cohort study using de-identified data retrieved from clinical records of COVID-19 patients in two isolation centers. Medical history, demographic data, symptoms, complications and laboratory investigations were extracted from clinical records of 406 confirmed COVID-19 hospitalized patients between Feb 2020 and July 2021. Hypertension and antihypertensive treatments were confirmed by medical history and clinical records. Continuous variables were presented as means ± standard deviation (SD) while categorical variables were presented as percent proportions. Logistic regression was used to assess the impact of antihypertensive drugs (RAAS inhibitors, CCBs, combination of RAAS inhibitors and CCBs and those not receiving medication) on the prognosis of COVID-19 patients and to explore the risk factors associated with mortality. Result: Out of 406 hospitalized COVID-19 patients, 242 (59.6%) had a history of hypertension. Hypertensive patients under the age of 65 years and receiving RAAS inhibitors or the combination of both RAAS inhibitors and CCBs were at higher risk of mortality than those on CCBs only (odds ratio [OR]: 4.45, 95% confidence interval [CI]: 1.56-12.56, P = 0.005 and OR:3.57, CI: 1.03-12.36, P = 0.045 respectively). Antihypertensive medications did not seem to influence mortality rates among hypertensive patients above 65 years. Routine laboratory investigations were not significantly different between the subgroups receiving different antihypertensive medications regardless of age. Cough was the only symptom associated with mortality among patients under 65 years (OR:2.34, CI:1.24-4.41, P = 0.009). Type II respiratory failure was significantly associated with death among hypertensives under 65 years (OR:5.43, CI:1.08-28.07, P = 0.044) whereas acute kidney injury and septic shocks are the common complications related to death among hypertensives above 65 years (OR:3.59, CI:1.54-8.36, P = 0.003 and OR:7.87, CI: 1.68-36.78, P = 0.009 respectively). Conclusion: Administration of CCBs may improve the outcome of COVID-19 hypertensive patients under 65 years of age. Antihypertensive treatment does not seem to influence the prognosis of COVID-19 patients above 65 years. Such results may affect management strategy of COVID-19 hypertensive patients. Type-II respiratory failure among patients under 65 years of age, acute kidney injury and septic shock among those above 65 years are the most serious complications that can lead to death regardless of blood pressure.

ABSTRACT

Background and purpose: There are limited studies on co-infection of COVID-19 and tuberculosis (TB). This study aimed to describe the clinical, radiological, laboratory characteristics, treatment and outcome of patients admitted with tuberculosis and COVID 19 co-infection. Materials and methods: In this retrospective study, we investigated all patients with either active TB or old TB and COVID-19 admitted to Qaemshahr Razi Teaching Hospital between 2020 and 2022. Results: A total of 9251 patients with COVID-19 were admitted to our hospital between February 2020 and May 2022. There were eight patients with pulmonary tuberculosis and COVID-19 co-infection, including five (62.5%) male patients. The mean age of these patients was 61.13±22.63 years old. The mean time of symptom onset to hospital admission was 15.13±30.56 days and 50% were diagnosed with active TB and other half had old TB. Four patients were admitted to the ICU, three of whom required ventilation. Finally, four (50%) patients deceased. In this study, among factors that influence patients' outcomes, only underlying diseases were significantly associated with death. Conclusion: Tuberculosis is assumed to cause a higher mortality risk in COVID-19 patients, especially in those with chronic underlying diseases.

ABSTRACT

Background: The long-term cardiovascular outcomes in COVID-19 survivors remain largely unclear. The aim of this study was to investigate the long-term cardiovascular outcomes in COVID-19 survivors. Method(s): This study used the data from the US Collaborative Network in TriNetX. From a cohort of more than 42 million records between January 1, 2019 and March 31, 2022, a total of 4 131 717 participants who underwent SARS-CoV- 2 testing were recruited. Study population then divided into two groups based on COVID-19 test results. To avoid reverse causality, the follow-up initiated 30 days after the test, and continued until 12 months. Hazard ratios (HRs) and 95% Confidence intervals (CIs) of the incidental cardiovascular outcomes were calculated between propensity score-matched patients with versus without SARS-CoV- 2 infection. Subgroup analyses on sex, and age group were also conducted. Sensitivity analyses were performed using different network, or stratified by hospitalization to explore the difference of geography and severity of COVID-19 infection. Result(s): The COVID-19 survivors were associated with increased risks of cerebrovascular diseases, such as stroke (HR [95% CI] = 1.618 [1.545-1.694]), arrhythmia related disorders, such as atrial fibrillation (HR [95% CI] = 2.407 [2.296-2.523]), inflammatory heart disease, such as myocarditis (HR [95% CI] = 4.406 [2.890-6.716]), ischemic heart disease (IHD), like ischemic cardiomyopathy (HR [95% CI] = 2.811 [2.477-3.190]), other cardiac disorders, such as heart failure (HR [95% CI] = 2.296 [2.200-2.396]) and thromboembolic disorders (e.g. pulmonary embolism: HR [95% CI] = 2.648 [2.443-2.870]). The risks of two composite endpoints, major adverse cardiovascular event (HR [95% CI] = 1.871 [1.816-1.927]) and any cardiovascular outcome (HR [95% CI] = 1.552 [1.526-1.578]), were also higher in the COVID-19 survivors than in the controls. Moreover, the survival probability of the COVID-19 survivors dramatically decreased in all the cardiovascular outcomes. The risks of cardiovascular outcomes were evident in both male and female COVID-19 survivors. Furthermore, the risk of mortality was higher in the elderly COVID-19 survivors (age >= 65 years) than in the young ones. Sensitivity analyses presented roughly similar results globally. Furthermore, the impact of COVID-19 on cardio-related outcomes appeared to be more pronounced in inpatients than in outpatients. Conclusion(s): The 12-month risk of incidental cardiovascular diseases is substantially higher in the COVID-19 survivors than the non-COVID- 19 controls. Clinicians and patients with a history of COVID-19 should pay attention to their cardiovascular health in long term.

ABSTRACT

Case Report: Atypical Hemolytic Uremic Syndrome (atypical HUS) is a rare and severe form of thrombotic microangiopathy (TMA) characterized by thrombocytopenia, intravascular hemolysis, and acute kidney injury with an incidence of 1 per million.1 Dysregulation and overactivation of the complement alternative pathway due to genetic mutations have been detected in 40-60% of patients with sporadic or familial atypical HUS.2,4 Triggers include viral illness, pregnancy, malignancy, sepsis, or sporadically with no known inciting event.1 Atypical HUS is a severe disease with a 2-10% risk of mortality, 33% risk of end-stage renal failure, and 50% chance of relapse.5 A 24-year-old female with prior history of atypical HUS at the age of 16 (with response to plasmapheresis) presented to the ER with a 5-day history of fever, chills, sore throat, nausea, vomiting, and dark urine. She tested positive for COVID-19. The exam revealed scleral icterus and scattered petechiae. Labs demonstrated nadir hemoglobin (Hgb) of 9.2 g/dL, platelet count of 52 000k/uL, haptoglobin < 30 mg/dL, peak LDH 1128U/L and creatinine 4.62 mg/dL. Urinalysis is consistent with hemoglobinuria. Schistocytes were noted on the peripheral smear. Rapid streptococcal antigen test and C3, C4, and IgA levels were unremarkable. Chest X-Ray, X-ray KUB, and ultrasound abdomen were unremarkable. The pregnancy test was negative. ADAMTS13 was >100%. Genetic analysis after the initial episode at age 16 revealed autosomal recessive inheritance c.193A > c gene mutations in C3. The patient received IV fluids, ceftriaxone for cystitis, and two units of Fresh Frozen Plasma. She initiated treatment with eculizumab. She also received the MENVEO and meningitis B vaccine per protocol due to the risk of meningitis from terminal complement deficiencies. After 4 infusions of eculizumab, patient's labs improved to platelet count of 307 000 k/uL, Hgb 12.2 g/ dL (nadir 9.2 g/dL), haptoglobin 78 mg/dL normalization of LDH and improved creatinine. Atypical HUS is a rare form of TMAwith mutations in C3 noted in 5% of cases. Complement cascade dysfunction leads to endothelial deposits and microvasculature damage. The resulting prothrombotic state causes obstructive microvascular thrombi predominantly affecting the kidneys but can cause multiorgan dysfunction. The SARS-CoV-2 virus may precipitate atypical HUS relapse due to endothelial damage and complement activation further intensified in patients with existing complement aberrations. Plasma exchange remains a standard of care for atypical HUS, as it effectively removes the antibodies and other proteins. Eculizumab a humanized monoclonal IgG antibody binds to complement proteins, preventing cleavage into C5a and C5b blocking C5b-9(MAC) activation. In patients with CFH, CFI, C3, and CFB mutations, eculizumab is the preferred intervention. Copyright © 2023 Southern Society for Clinical Investigation.

ABSTRACT

Case report - Introduction: This case highlights the dilemma of keeping rheumatoid arthritis disease under control in active cancer cases and establishing a consistent multidisciplinary dialogue during a pandemic and staffing crises. During chemotherapy and active cancer treatment, disease-modifying therapies (conventional and biologic) are often stopped. In some cases, the potential benefits versus risks of restarting usual therapies have to be balanced against risks of suppressing disease activity with highdose steroids. Risks of infection (common and atypical) need to be considered. Case report - Case description: A is a 67-year-old female nonsmoker diagnosed with seropositive rheumatoid arthritis (RF, anti - CCP positive) in 2008. Other conditions include type 2 diabetes, atrial fibrillation (on warfarin), hypothyroidism and obstructive sleep apnoea. Due to active disease, despite triple therapy (methotrexate, sulphasalazine and hydroxychloroquine), anti-TNF therapy (etanercept) commenced in 2009 with primary non-response. However, she responded well to B-cell therapy (rituximab) in conjunction with oral methotrexate (25mg weekly) receiving annual infusions from 2010 to 2016. In 2017, an elective sleeve gastrectomy procedure for high BMI was abandoned after peritoneal deposits of concern were noted. Histology and CT imaging were consistent with a primary peritoneal malignancy (Stage 3c low-grade serous adenocarcinoma). Treatment involved debulking surgery (total abdominal hysterectomy, bilateral salpinoophorectomy, omentectomy) and tamoxifen. Treatment for rheumatoid arthritis stalled during this period but as frequent steroids were required for active joint inflammation, in agreement with the oncologists, she had a rituximab cycle in 2018. Unfortunately, in 2019 she had signs of cancer progression (elevated tumour markers, CT imaging) and has subsequently started carboplatin chemotherapy. She has been unable to continue methotrexate or rituximab pending completion of the chemotherapy cycles (ongoing). However, her arthritis is now uncontrolled without increased steroids. Due to recurrent flares, her maintenance dose has been increased from 5mg to 7.5-10mg prednisolone daily until we can establish if it is safe and appropriate to recommence her usual arthritis regime. Even without disease-modifying therapy like methotrexate and rituximab, risk of infection (including atypical ones) is still significant with the combination of chemotherapy and steroids. Risk of progressive joint damage and adverse quality of life with active arthritis also needs to be considered. Staffing crises, exacerbated by COVID pandemic issues, have added to complexity of decision making and coordination of regular multidisciplinary discussions regarding treatment. Case report - Discussion: Cancer is a known association in rheumatoid arthritis patients with a twofold higher risk of lymphoma compared to the general population. Whether condition or treatment affects risk remains unclear as immune dysregulation is relevant in both autoimmunity and cancer. Paraneoplastic, recent onset arthritis, chemotherapy- or immunotherapy-induced arthralgia/arthritis are also well documented. This case had a seropositive rheumatoid arthritis phenotype quite a few years prior to cancer diagnosis. Primary peritoneal cancer is uncommon, often presenting as in this case as an incidental finding. It is usually treated like ovarian cancer Whilst methotrexate has been implicated in lung cancer, melanoma and non-Hodgkin lymphoma, overall safety data suggest any risk is quite low (e.g., EBV-associated lymphoproliferative disorders usually resolve with drug discontinuation). It is also a known chemotherapeutic agent. Anti-TNF treatment algorithms generally exclude patients with recent cancer. Rituximab, originally developed as a cancer drug, is not thought to affect risk of cancer development or progression. Treatment with disease-modifying therapy (conventional and biologics) is often withheld in patients with active malignancy undergoing chemotherapy due to a theo etical risk of potentiated immunosuppression and toxicity, particularly cytopaenias. However, maintaining arthritis control with glucocorticoids also has short- and long-term risks. Combining chemotherapy agents like carboplatin with methotrexate has been used for urothelial carcinoma and can be well tolerated with close monitoring of haematological parameters. Thus, it could be argued this patient is at risk of infections whichever treatment approach is taken and regaining control of arthritis with recommencement of methotrexate and rituximab is much better for her quality of life. Regular multidisciplinary discussions are important to outline risks versus benefits of combined treatment. This may be difficult in practice during staffing crises. Covid risk in patients receiving rituximab and/or chemotherapy, timing and response to COVID vaccination are also important considerations. Case report - Key learning points: . Primary peritoneal cancer is uncommon and can present as an incidental finding . Whilst treatment for progressive cancer is important, withholding rheumatoid arthritis treatment can have a significant adverse impact on quality of life . Morbidity and mortality risks of stopping treatment versus combined treatment (cancer therapy and disease-modifying therapy) ideally needs to be fully discussed and agreed with the patient and all care providers - lack of "named" providers, restructuring, redeployment, multi-specialty care and a global pandemic can make coordination of this difficult.

ABSTRACT

Clonal hematopoiesis, especially that of indeterminate potential (CHIP), has been associated with age-related diseases, such as those contributing to a more severe COVID-19. Four studies have attempted to associate CHIP with COVID-19 severity without conclusive findings. In the present work, we explore the association between CHIP and COVID-19 mortality. Genomic DNA extracted from peripheral blood of COVID-19 patients (n = 241 deceased, n = 239 survivors) was sequenced with the Myeloid Solutions™ panel of SOPHiA Genetics. The association between clonality and age and clonality and mortality was studied using logistic regression models adjusted for sex, ethnicity, and comorbidities. The association with mortality was performed with patients stratified into four groups of age according to the quartiles of the distribution: 60-74 years, 75-84 years, 85-91 years, and 92-101 years. Clonality was found in 38% of the cohort. The presence of CHIP variants, but not the number, significantly increased with age in the entire cohort of COVID-19 patients, as well as in the group of survivors (p < 0.001). When patients were stratified by age and the analysis adjusted, CHIP classified as pathogenic/likely pathogenic was significantly more represented in deceased patients compared with survivors in the group of 75-84 years (34.6% vs 13.7%, p = 0.020). We confirmed the well-established linear relationship between age and clonality in the cohort of COVID-19 patients and found a significant association between pathogenic/likely pathogenic CHIP and mortality in patients from 75 to 84 years that needs to be further validated.

ABSTRACT

BACKGROUND AND OBJECTIVES: Patients who were hospitalized with coronavirus disease 2019 (COVID-19) infection are at high risk of AKI and KRT, especially in the presence of CKD. The Dapagliflozin in Respiratory Failure in Patients with COVID-19 (DARE-19) trial showed that in patients hospitalized with COVID-19, treatment with dapagliflozin versus placebo resulted in numerically fewer participants who experienced organ failure or death, although these differences were not statistically significant. We performed a secondary analysis of the DARE-19 trial to determine the efficacy and safety of dapagliflozin on kidney outcomes in the overall population and in prespecified subgroups of participants defined by baseline eGFR. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: The DARE-19 trial randomized 1250 patients who were hospitalized (231 [18%] had eGFR <60 ml/min per 1.73 m2) with COVID-19 and cardiometabolic risk factors to dapagliflozin or placebo. Dual primary outcomes (time to new or worsened organ dysfunction or death, and a hierarchical composite end point of recovery [change in clinical status by day 30]), and the key secondary kidney outcome (composite of AKI, KRT, or death), and safety were assessed in participants with baseline eGFR <60 and ≥60 ml/min per 1.73 m2. RESULTS: The effect of dapagliflozin versus placebo on the primary prevention outcome (hazard ratio, 0.80; 95% confidence interval, 0.58 to 1.10), primary recovery outcome (win ratio, 1.09; 95% confidence interval, 0.97 to 1.22), and the composite kidney outcome (hazard ratio, 0.74; 95% confidence interval, 0.50 to 1.07) were consistent across eGFR subgroups (P for interaction: 0.98, 0.67, and 0.44, respectively). The effects of dapagliflozin on AKI were also similar in participants with eGFR <60 ml/min per 1.73 m2 (hazard ratio, 0.71; 95% confidence interval, 0.29 to 1.77) and ≥60 ml/min per 1.73 m2 (hazard ratio, 0.69; 95% confidence interval, 0.37 to 1.29). Dapagliflozin was well tolerated in participants with eGFR <60 and ≥60 ml/min per 1.73 m2. CONCLUSIONS: The effects of dapagliflozin on primary and secondary outcomes in hospitalized participants with COVID-19 were consistent in those with eGFR below/above 60 ml/min per 1.73 m2. Dapagliflozin was well tolerated and did not increase the risk of AKI in participants with eGFR below or above 60 ml/min per 1.73 m2.

ABSTRACT

The most enduring measure of how individuals make personal decisions affecting their health and safety is the compensating wage differential for job safety risk revealed in the labor market via hedonic equilibrium outcomes. The decisions in turn reveal the value of a statistical life (VSL), the value of a statistical injury (VSI), and the value of a statistical life year (VSLY), which have both mortality and morbidity aspects that we describe and apply here. All such tradeoff rates play important roles in policy decisions concerning improving individual welfare. Specifically, we explicate the recent empirical research on VSL and its related concepts and link the empirical results to the ongoing examinations of many government policies intended to improve individuals' health and longevity. We pay special attention to recent issues such as the COVID pandemic and newly emerging foci on distributional consequences concerning which demographic groups may benefit most from certain regulations. © 2023 by Emerald Publishing Limited.

ABSTRACT

Background: Dialysis quality ismeasured by Kt/V, it is one of the most important parameter for assessing hemodialysis for patients. Decreased Kt/V is associated with increased mortality and increased risk of complications, normal or increased Kt/V is associated with decreased mortality and complication rates. Guidelines have recommended Kt/V of 1.2 as the minimum dose for thrice-weekly HD. We analyzed the Kt/v, mortality and risk of complications in our hemodialysis center patients Methods or Case description: We analyzed patients from 2021-2022, within 1 year 50 patients undergoing hemodialysis 3 times a week were analyzed. Results or Learning points: The average Kt/V was 1.38. Patient mortality was minimal during this period and was related to Covid 19 infection, 3 patients died, one from sepsis and two from Covid 19 infection. 5 patients were hospitalized several times with hyperhydration and accompanying consequences, which were not related to dialysis, but with non-compliance with the regimen and increased fluid intake. Conclusion(s): In general, the patients felt satisfactory and there were no complaints. Therefore, it can be considered that Kt/V above 1.3 is satisfactory and reduces the risk of mortality and complications.

ABSTRACT

BACKGROUND: Chest CT on coronavirus disease (COVID-19) has been extensively investigated. Acute kidney injury (AKI) has been widely described among COVID patients, but the role of kidney imaging has been poorly explored. The aim of this study is to clarify the role of opportunistic kidney assessment on non-enhanced chest CT. METHODS: We collected data on patients with COVID-19 consecutively admitted to our institution who underwent chest CT (including the upper parts of kidneys as per protocol). Three ROIs of 0.5-0.7 cm2 were positioned in every kidney. The values of renal parenchyma attenuation (RPA) and the presence of perirenal fat stranding (PFS) were analyzed. The primary and secondary outcomes were the occurrence of AKI and death. RESULTS: 86 patients with COVID-19 and unenhanced chest CT were analyzed. The cohort was split into CT RPA quartiles. Patients with a CT RPA <24 HU were more likely to develop AKI when compared with other patients (χ2 = 2.77, p = 0.014): at multivariate logistic regression analysis, being in the first quartile of CT RPA was independently associated with a four times higher risk of AKI (HR 4.56 [95% CI 1.27-16.44, p = 0.020). Within a mean 22 ± 15 days from admission, 32 patients died (37.2%). Patients with PFS were more likely to die as compared to patients without it (HR 3.90 [95% CI 1.12-13.48], p = 0.031). CONCLUSIONS: Detection of low RPA values and of PFS in COVID-19 patients independently predicts, respectively, the occurrence of AKI and an increased risk for mortality. Therefore, opportunistic kidney assessment during chest CT could help physicians in defining diagnostic and therapeutic strategies.

ABSTRACT

Suicide is a significant and global public mental health problem. The suicide rate in Iran is disturbingly high;it has been reported to be 5.3 per 100.000 individuals. A meta-analysis indicated that physicians were at risk, with a reported standardized mortality risk of 1.44%. The rate of suicide has also been reported to be increasing in residents, in addition to a higher rate in senior specialists. Several possible suicides among Iran's resident doctor population have occurred in a short period, underlining the vital need for suicide prevention initiatives.

ABSTRACT

Acute kidney injury (AKI) is the second prevalent organ damage among COVID-19 infected individuals, which mainly affects those with critical diseases or underlying kidney disorders. Emerging data have suggested that AKI is associated with adverse outcomes, severe COVID-19 disease, and high mortality. However, the true nature and pathophysiology of COVID-19-associated kidney injury, and its effect on patients with underlying kidney diseases and transplant recipients, still remains controversial. Accordingly, this review study aimed primarily to describe the history of AKI in COVID-19 infected patients and to achieve a robust understanding of the latest findings on the mechanism of the injury. Secondly, this systematic and precise review of the literature concerning the aspects of AKI in infected patients with chronic kidney disease and transplant recipients provided a comprehensive report of mortality in these individuals. Finally, the present research suggested the possible protective measures that physicians can take to prevent, control, and treat this condition. Our study paves the way for future works with a more robust methodology to better understand COVID-19-related kidney injury.

ABSTRACT

BACKGROUND: Oncology patients are a particularly vulnerable group to the severe course of COVID-19 due to, e.g., the suppression of the immune system. The study aimed to find links between parameters registered on admission to the hospital and the risk of later death in cancer patients with COVID-19. METHODS: The study included patients with a reported history of malignant tumor (n = 151) and a control group with no history of cancer (n = 151) hospitalized due to COVID-19 between March 2020 and August 2021. The variables registered on admission were divided into categories for which we calculated the multivariate Cox proportional hazards models. RESULTS: Multivariate Cox proportional hazards models were successfully obtained for the following categories: Patient data, Comorbidities, Signs recorded on admission, Medications used before hospitalization and Laboratory results recorded on admission. With the models developed for oncology patients, we identified the following variables that registered on patients' admission were linked to significantly increased risk of death. They are: male sex, presence of metastases in neoplastic disease, impaired consciousness (somnolence or confusion), wheezes/rhonchi, the levels of white blood cells and neutrophils. CONCLUSION: Early identification of the indicators of a poorer prognosis may serve clinicians in better tailoring surveillance or treatment among cancer patients with COVID-19.

ABSTRACT

BACKGROUND: Information on COVID-19 vaccination effects on mortality among patients hospitalized with COVID-19 could inform vaccination outreach efforts and increase understanding of patient risk. OBJECTIVE: Determine the associations of vaccination status with mortality in adult patients hospitalized with COVID-19. DESIGN: This retrospective cohort study assessed the characteristics and mortality rates of adult patients hospitalized with COVID-19 across 21 healthcare systems in the USA from January 1, 2021, to January 31, 2022. PARTICIPANTS: Adult patients admitted to participating hospitals who had COVID-19 diagnoses and/or positive PCR tests and completed their hospital stay via discharge or death. MAIN MEASURE: In-hospital mortality vs. discharge (outcome) and patient age, sex, race, ethnicity, BMI, insurance status, comorbidities, and vaccination status extracted from the electronic health record (EHR). KEY RESULTS: Of 86,732 adult patients hospitalized with COVID-19, 45,082 (52%) were female, mean age was 60 years, 20,800 (24%) were Black, and 22,792 (26.3%) had one or more COVID-19 vaccinations. Statistically adjusted mortality rates for unvaccinated and vaccinated patients were 8.3% (95% CI, 8.1-8.5) and 5.1% (95% CI, 4.8-5.4) respectively (7.9% vs. 4.5% with no immune compromise). Vaccination was associated with especially large reductions in mortality for obese (OR = 0.67; 95% CI 0.56-0.80) and severely obese (OR = 0.52; 95% CI, 0.41-0.67) patients and for older patients (OR = 0.99; 95% CI, 0.98-0.99). Mortality likelihood was higher later in the study period (August 2021-January 31, 2022) than earlier (January 1, 2021-July 30, 2021) (OR = 1.10; 95% CI = 1.04-1.17) and increased significantly for vaccinated patients from 4.6% (95% CI, 3.9-5.2%) to 6.5% (95% CI, 6.2-6.9%). CONCLUSIONS: Patients vaccinated for COVID-19 had reduced mortality, especially for obese/severely obese and older individuals. Vaccination's protective effect against mortality declined over time and hospitalized obese and older individuals may derive especially great benefit from prior vaccination against SARS-CoV-2.

ABSTRACT

Introduction: Patients with mental disorders mainly schizophrenia represent a vulnerable population. In Covid-19 pandemic situation , could schizophrenia be considered as a significant mortality risk factor ? Objectives: In this study, we aimed to explore the odds of significant COVID-19 mortality among schizophrenia patients Methods: Our literature review was based on the PubMed interface and adapted for 2 databases: Science Direct and Google Scholar using the following combination ( schizophrenia [MeSH terms]) AND (COVID-19, mortality[MeSH terms]) Results: Our review included 4 population-based cohort studies covering the period from december 2019 to May 2021. The data showed increased mortality risk among individuals with schizophrenia who have had COVID-19. Indeed, this high rate of mortality maybe associated with multiple factors such as unhealthy lifestyle , low socioeconomic status and comorbidities as obesity, diabetes and cardiovascular conditions. The use of antipsychotics can be considered as a risk factor regarded its immunomodulatory effects. Furthermore, stigma and discrimination towards mental illnesses particularly schizophrenia might have contributed to a worse prognosis . Conclusion(s): Schizophrenia is a severe mental disorder , associated with an increased high risk Covid-19. Thus, this population require enhanced preventive and disease management strategies.
