Experience of 101 patients with coronavirus infectious disease 2019 (COVID-19) at a tertiary care center in Japan

IntroductionClusters of novel coronavirus infectious disease of 2019 (COVID-19) have spread to become a global pandemic imposing a significant burden on healthcare systems. The lack of an effective treatment and the emergence of varied and complicated clinical courses in certain populations have rendered treatment of patients hospitalized for COVID-19 difficult.MethodsTokyo Metropolitan Tama Medical Center, a public tertiary acute care center located in Tokyo, the epicenter of COVID-19 in Japan, has been admitting patients with COVID-19 since February 2020. The present, retrospective, case-series study aimed to investigate the clinical course and outcomes of patients with COVID-19 hospitalized at the study institution.ResultsIn total, 101 patients with COVID-19 were admitted to our hospital to receive inpatient care. Eleven patients (10.9%) received ECMO, and nine patients (8.9%) died during hospitalization after COVID-19 was diagnosed. A history of smoking and obesity were most commonly encountered among patients with a complicated clinical course. Most patients who died requested to be transferred to advanced palliative care in the early course of their hospitalization.ConclusionsOur experience of caring for these patients demonstrated a relatively lower mortality rate and higher survival rate in those with extracorporeal membrane oxygenation placement than previous reports from other countries and underscored the importance of proactive, advanced care planning in the early course of hospitalization.

Iatrogenic anaemia and transfusion thresholds in ICU patients with COVID-19 disease at a tertiary care hospital

BackgroundPatients with severe COVID-19 disease frequently develop anaemia as the result of multiple mechanisms and often receive transfusions. The aims of this study were to assess the impact of repeated blood samplings on patients’ anaemic state using standard-volume tubes, in comparison with the hypothetical use of low-volume tubes and to evaluate the transfusion policy adopted.Study design and methodsTransfusion data of mechanically ventilated non-bleeding patients with COVID-19 disease hospitalized in ICU for a minimum of 20 days were recorded. The total volume of blood drawn for samplings with standard-volume tubes and the corresponding red blood cell mass (RBCM) removed during hospitalization for each patient were calculated and compared with the hypothetical use of low-volume tubes.ResultsTwenty-four patients fulfilled the inclusion criteria. Ten patients were anaemic at ICU admission (41.7 %). Overall, 6658 sampling tubes were employed, for a total of 16,786 mL of blood. The median RBCM subtracted by blood samplings per patient accounted for about one third of the total patients’ RBCM decrease until discharge.The use of low-volume tubes would have led to a median saving of about one third of the drawn RBCM.Eleven patients were transfused (45.8 %) at a mean Hb value of 7.7 (± 0.5) g/dL.ConclusionThe amount of blood drawn for sampling has a significant role in the development of anaemia and the use of low-volume tubes could minimize the problem.Large high-powered studies are warranted to assess the more appropriate transfusion thresholds in non-bleeding critically ill patients with COVID-19 disease.     

Holistic care model of time-sharing management for severe and critical COVID-19 patients

The rapid global outbreak of coronavirus disease 2019 (COVID-19) and the surge of infected patients have led to the verge of exhaustion of critical care medicine resources worldwide, especially with regard to critical care staff. A holistic care model on time-sharing management for severe and critical COVID-19 patients is proposed, which includes formulation of individualized care objectives and plans, identification of care tasks in each shift and making detailed checklist, and management of quality of care. This study was conducted in the COVID-19 treatment center of Harbin, Heilongjiang Province. The data collected from the treatment center were recorded and analyzed. From the results we can deduce that it is especially suitable for non-intensive care unit (non-ICU) nurses to adapt care management mode of ICU as soon as possible and ensure the quality and efficiency of care during the epidemic. The holistic care model on time-sharing management for severe and critical cases with COVID-19 proposed based on our daily work experiences can assist in improving the quality and efficiency of care, thus reducing the mortality rate of patients in ICU.     

Comparison of laboratory parameters,clinical symptoms and clinical outcomes of COVID-19 and influenza in pediatric patients: A systematic review and meta-analysis

BACKGROUNDNew and more severe clinical manifestations associated with the coronavirus disease 2019 (COVID-19) are emerging constantly in the pediatric age group. Patients in this age group are also primary carriers of the influenza virus and are at a higher risk of developing severe infection. However, studies comparing influenza and COVID-19 to show which condition causes a more severe form of disease amongst the pediatric age group are scarce. AIMTo compare the laboratory results, clinical symptoms and clinical outcomes in pediatric patients with COVID-19 and influenza.METHODSA systematic and comprehensive search was carried out in databases and search engines, including EMBASE, Cochrane, MEDLINE, ScienceDirect and Google Scholar from 1964 until January 2022. A meta-analysis was carried out using a random-effects model and pooled odds ratio (OR) or standardized mean difference (SMD) and 95%CI.RESULTSA total of 16 studies satisfied the inclusion criteria. Pediatric COVID-19 patients had a significantly reduced risk of cough (pooled OR = 0.16; 95%CI: 0.09 to 0.27), fever (pooled OR = 0.23; 95%CI: 0.12 to 0.43), and dyspnea (pooled OR = 0.54; 95%CI: 0.33 to 0.88) compared to influenza patients. Furthermore, total hemoglobin levels (pooled SMD = 1.22; 95%CI: 0.29 to 2.14) in COVID-19 patients were significantly higher as compared to pediatric influenza patients. There was no significant difference in symptoms such as sore throat, white blood cell count, platelets, neutrophil and lymphocytes levels, and outcomes like mortality, intensive care unit admission, mechanical ventilation or length of hospital stay.CONCLUSIONCOVID-19 is associated with a significantly lower rate of clinical symptoms and abnormal laboratory indexes compared to influenza in the pediatric age group. However, further longitudinal studies of the outcomes between influenza and COVID-19 pediatric patients are needed.     

Antibody response after COVID-19 vaccine BNT162b2 on health care workers in Japan

BackgroundVaccination is one of the most important tools to control the COVID-19 pandemic. However, there is little information on the antibody response in humans after the COVID-19 vaccination.MethodsThis single-center, prospective study was conducted in Yokohama, Japan. We included health care workers who had received two doses of COVID-19 vaccination (BNT162b2) 21 days apart. We measured serum immunoglobulin G (IgG) to nucleoprotein and spike protein of SARS-CoV-2 with commercially available kits before and 7, 14, and 35 days after the first dose of vaccination.ResultsA total of 104 workers participated in this study. Of these, 7 participants were seropositive with antibodies to spike protein at baseline and 4 of the 7 seropositive participants had COVID-19 history. The mean level of IgG to spike protein (QT) was 45.2, 1219, 2845, and 23489 AU/mL at baseline, on days 7, 14, and 35, respectively, although the values for nucleoprotein (NG) were 0.2, 0.21, 0.22, and 0.19 S/C, respectively. On day 7, QT in seropositive participants at baseline was elevated, whereas it was not elevated in seronegative participants at baseline until day 14.ConclusionsQT was elevated over the cutoff in all the participants at day 35, but NG did not change between baseline and day 35.     

Epidemiological and clinical characteristics of 65 hospitalized patients with COVID-19 in Liaoning,China

BACKGROUNDCoronavirus disease 2019 (COVID-19) has spread rapidly to multiple countries through its infectious agent severe acute respiratory syndrome coronavirus 2. The severity, atypical clinical presentation, and lack of specific anti-viral treatments have posed a challenge for the diagnosis and treatment of COVID-19. Understanding the epidemiological and clinical characteristics of COVID-19 cases in different geographical areas is essential to improve the prognosis of COVID-19 patients and slow the spread of the disease.AIMTo investigate the epidemiological and clinical characteristics and main therapeutic strategy for confirmed COVID-19 patients hospitalized in Liaoning Province, China.METHODSAdult patients (n = 65) with confirmed COVID-19 were enrolled in this retrospective study from January 20 to February 29, 2020 in Liaoning Province, China. Pharyngeal swabs and sputum specimens were collected from the patients for the detection of severe acute respiratory syndrome coronavirus 2 nucleic acid. Patient demographic information and clinical data were collected from the medical records. Based on the severity of COVID-19, the patients were divided into nonsevere and severe groups. All patients were followed until March 20, 2020.RESULTSThe mean age of 65 COVID-19 patients was 45.5 ± 14.4 years, 56.9% were men, and 24.6% were severe cases. During the 14 d before symptom onset, 25 (38.5%) patients lived or stayed in Wuhan, whereas 8 (12.3%) had no clear history of exposure. Twenty-nine (44.6%) patients had at least one comorbidity; hypertension and diabetes were the most common comorbidities. Compared with nonsevere patients, severe patients had significantly lower lymphocyte counts [median value 1.3 × 10⁹/L (interquartile range 0.9-1.95) vs 0.82 × 10⁹/L (0.44-1.08), P < 0.001], elevated levels of lactate dehydrogenase [450 U/L (386-476) vs 707 U/L (592-980), P < 0.001] and C-reactive protein [6.1 mg/L (1.5-7.2) vs 52 mg/L (12.7-100.8), P < 0.001], and a prolonged median duration of viral shedding [19.5 d (16-21) vs 23.5 d (19.6-30.3), P = 0.001]. The overall median viral shedding time was 19.5 d, and the longest was 53 d. Severe patients were more frequently treated with lopinavir/ritonavir, antibiotics, glucocorticoid therapy, immunoglobulin, thymosin, and oxygen support. All patients were discharged following treatment in quarantine.CONCLUSIONOur findings may facilitate the identification of severe cases and inform clinical treatment and quarantine decisions regarding COVID-19.     

A comparative analysis of the outcomes of patients with influenza or COVID-19 in a tertiary hospital in Belgium

IntroductionThe COVID-19 pandemic has emerged as a global health problem, associated with high morbidity and mortality rates. The aim of this study was to compare the outcomes of hospitalized patients with COVID-19 or with seasonal influenza in a teaching hospital in Belgium.MethodsIn this retrospective, single-center cohort study, 1384 patients with COVID-19 and 226 patients with influenza were matched using a propensity score with a ratio of 3:1. Primary outcomes included admission to intensive care unit (ICU), intubation rates, hospital length of stay, readmissions within 30 days and in-hospital mortality. Secondary outcomes included pulmonary bacterial superinfection, cardiovascular complications and ECMO.ResultsBased on the analysis of the matched sample, patients with influenza had an increased risk of readmission within 30 days (Risk Difference (RD): 0.07, 95% CI: 0.03 to 0.11) and admission to intensive care unit (RD: 0.09, 95% CI: 0.03 to 0.15) compared with those with COVID-19. Patients with influenza had also more pulmonary bacterial superinfections (46.2% vs 7.4%) and more cardiovascular complications (32% vs 3.9%) than patients with COVID-19.However, a two-fold increased risk of mortality (RD: ?0.10, 95% CI: 0.15 to ?0.05) was observed in COVID-19 compared to influenza. ECMO was also more required among the COVID-19 patients who died than among influenza patients (5% vs 0%).ConclusionsCOVID-19 is associated with a higher in-hospital mortality compared to influenza infection, despite a high rate of ICU admission in the influenza group. These findings highlighted that the severity of hospitalized patients with influenza should not be underestimated.     

Impacts and challenges of United States medical students during the COVID-19 pandemic

The delivery of medical student education has changed rapidly during the coronavirus disease 2019 (COVID-19) pandemic. Students in their pre-clinical years have transitioned to online courses and examinations. Students in their clinical years are not permitted on clinical rotations, and face uncertainties in career exploration and the residency application process. Medical students in all stages of training are volunteering and helping their communities. The future presence of COVID-19 throughout the United States is unknown, and medical students are eager to return to their training. This paper outlines current challenges in medical student education and the various responses that have been adopted. We also discuss possible future directions for students through involvement in telemedicine, outpatient clinic visits, and non-respiratory inpatient care tasks as adequate personal protective equipment, COVID-19 testing, and resources become more widely available.

In-hospital use of ACE inhibitors/angiotensin receptor blockers associates with COVID-19 outcomes in African American patients

BACKGROUNDThe angiotensin-converting enzyme (ACE) D allele is more prevalent among African Americans compared with other races and ethnicities and has previously been associated with severe coronavirus disease 2019 (COVID-19) pathogenesis through excessive ACE1 activity. ACE inhibitors/angiotensin receptor blockers (ACE-I/ARB) may counteract this mechanism, but their association with COVID-19 outcomes has not been specifically tested in the African American population.METHODSWe identified 6218 patients who were admitted into Mount Sinai hospitals with COVID-19 between February 24 and May 31, 2020, in New York City. We evaluated whether the outpatient and in-hospital use of ACE-I/ARB is associated with COVID-19 in-hospital mortality in an African American compared with non–African American population.RESULTSOf the 6218 patients with COVID-19, 1138 (18.3%) were ACE-I/ARB users. In a multivariate logistic regression model, ACE-I/ARB use was independently associated with a reduced risk of in-hospital mortality in the entire population (OR, 0.655; 95% CI, 0.505–0.850; P = 0.001), African American population (OR, 0.44; 95% CI, 0.249–0.779; P = 0.005), and non–African American population (OR, 0.748, 95% CI, 0.553–1.012, P = 0.06). In the African American population, in-hospital use of ACE-I/ARB was associated with improved mortality (OR, 0.378; 95% CI, 0.188–0.766; P = 0.006), whereas outpatient use was not (OR, 0.889; 95% CI, 0.375–2.158; P = 0.812). When analyzing each medication class separately, ARB in-hospital use was significantly associated with reduced in-hospital mortality in the African American population (OR, 0.196; 95% CI, 0.074–0.516; P = 0.001), whereas ACE-I use was not associated with impact on mortality in any population.CONCLUSIONIn-hospital use of ARB was associated with a significant reduction in in-hospital mortality among COVID-19–positive African American patients.FUNDINGNone.     

Knowledge,attitude, and practice regarding COVID-19 among COVID-19 patients and their correlation with the outcomes: A cross-sectional study

Objective: To assess the knowledge, attitude, and practice (KAP) regarding COVID-19 among COVID-19 patients and their relation with the outcomes.Methods: This cross-sectional study was carried out among COVID-19 patients (18-year-old or older) consecutively admitted to a dedicated COVID-19 hospital located in northwest Rajasthan, India. Data regarding socio-demographic parameters, KAP, and primary composite outcome (admission to intensive care unit, mechanical ventilation, or in-hospital death) were collected. KAP scores were compared between different demographic variables and primary composite outcomes. Association between different demographic variables, primary composite outcomes, and KAP scores were determined through multivariate linear regression. Besides, the correlation among KAP scores was analyzed. Results: Out of the total 222 patients, most of them (65.76％) had average KAP scores towards COVID-19. The mean scores for knowledge were 7.88, with an overall correct rate of 71.63％; the mean attitude scores were 2.42, with an overall correct rate of 60.50％; the mean practice scores were 5.12, with an overall correct rate of 64.00％. Patients who met the primary composite outcomes had higher knowledge scores, but lower attitude and practice scores. The result showed a significant positive correlation between the level of education, socioeconomic class, and knowledge, attitude, and practice towards COVID-19. Knowledge towards COVID-19 was significantly associated with a positive attitude and good practice. Conclusions: Our findings show that adult COVID-19 patients have average KAP towards COVID-19 among COVID-19 patients. Poor attitude and practice towards COVID-19 are associated with adverse outcomes, so it is suggested to strengthen attitude and practice towards COVID-19 to improve the outcomes.     

Association between COVID-19 vaccines and the menstrual cycle in young Japanese women

IntroductionAlthough several studies have investigated the association between coronavirus disease 2019 (COVID-19) vaccines and the menstrual cycle, available data are limited. Therefore, this study investigated the effect of COVID-19 vaccines on the menstrual cycle and the effect of the menstrual cycle phase on the vaccine side effects during vaccine administration in Japan.MethodsA self-administered questionnaire was used to collect data on the date of vaccination; type of vaccine; type, grade, and duration of the side effects; regularity of menstruation; normal length of the menstrual cycle; and the day one date of menstruation around vaccination. The survey was conducted from October 2021 to March 2022.ResultsThe difference between the predicted and actual menstrual cycle length was 1.9 ± 3.0, 1.6 ± 2.8 (p = 0.557), and 2.5 ± 3.8 (p = 0.219) days before vaccination and after the first and second dose of the vaccine, respectively. In participants who received vaccinations twice within a single menstrual cycle, this difference was 1.3 ± 3.5 and 3.9 ± 3.3 (p = 0.045) days before and after vaccination, respectively. The grade and proportion of the side effects after the second dose of the vaccine was highest during the menstrual period and lowest during the ovulation period, with a significant effect on headache and chills.ConclusionCOVID-19 vaccines tended to prolong the menstrual cycle. The side effects of the COVID-19 vaccine tended to be at a maximum when vaccination occurred during the menstrual period and minimal during the ovulation period.     

Staff experiences,perceptions of care,and communication in the intensive care unit during the COVID-19 pandemic in Australia

BackgroundIn 2020, during the first wave of the COVID-19 pandemic in Australia, hospital intensive care units (ICUs) revised patient care practices, curtailed visiting, and augmented the use of personal protective equipment to protect patients, staff, and the community from viral transmission.AimThe aim was to explore ICU staff experiences and perceptions of care and communication with patients during the COVID-19 pandemic to understand how alternative ways of working have influenced work processes, relationships, and staff morale.MethodsThis was a qualitative exploratory design study using audio-recorded and transcribed interviews with 20 ICU staff members. Data were analysed using thematic analysis.FindingsFour major themes were derived from the data: (i) Communication and connection, (ii) Psychological casualties, (iii) Caring for our patients, and (iv) Overcoming challenges. Patient care was affected by diminished numbers of critical care qualified staff, limited staff entry to isolation rooms, and needing to use alternative techniques for some practices. The importance of effective communication from the organisation and between clinicians, families, and staff members was emphasised. personal protective equipment hindered communication between patients and staff and inhibited nonverbal and verbal cues conveying empathy in therapeutic interactions. Communication with families by phone or videoconference was less satisfying than in-person encounters. Some staff members suffered psychological distress, especially those working with COVID-19 patients requiring extracorporeal membrane oxygenation. Moral injury occurred when staff members were required to deny family access to patients. Workload intensified with increased patient admissions, additional infection control requirements, and the need to communicate with families using alternative methods.ConclusionThe results of this study reflect the difficulties in communication during the early stages of the COVID-19 pandemic. Communication between staff members and families may be improved using a more structured approach. Staff reported experiencing psychological stress when separating families and patients or working in isolation rooms for prolonged periods. A flexible, compassionate response to family presence in the ICU is essential to maintain patient- and family-centred care.
