Risk Factors for Therapeutic Intervention of Remdesivir in Mild to Moderate COVID-19—A Single-Center Retrospective Study of the COVID-19 Fourth Pandemic Period in Wakayama, Japan

Background and Objectives: The incidence of coronavirus disease 2019 (COVID-19) has increased in Wakayama, Japan, due to the spread of the highly infectious B.1.1.7 variant. Before this event, the medical systems were almost unaffected. We aimed to assess the clinical characteristics of patients hospitalized with COVID-19 and the risk factors for therapeutic intervention of remdesivir during the fourth pandemic period in Wakayama, Japan. Materials and Methods: This single-center retrospective study enrolled 185 patients with mild to moderate COVID-19 hospitalized in our hospital without intensive care between 14 March and 31 May 2021. Results: In this period, 125 (67.6%) of the 185 patients had the B.1.1.7 variant. Sixty-three patients (34.1%) required remdesivir treatment. Age upon admission and length of hospitalization were significantly different between remdesivir treatment and careful observation groups (mean (standard deviation); 59.6 (14.7) versus 45.3 (20.6) years; p < 0.001 and median (interquartile range); 10 (9–12) versus 9 (8–10) years; p < 0.001). One patient was transferred to another hospital because of disease progression. At hospital admission, age ≥60 years (odds ratio (OR) 6.90, p < 0.001), a previous history of diabetes mellitus (OR 20.9, p = 0.002), B.1.1.7 variant (OR 5.30; p = 0.005), lower respiratory symptoms (OR 3.13, p = 0.011), headache (OR 3.82, p = 0.011), and fever ≥37.5 °C (OR 4.55, p = 0.001) were independent risk factors to require remdesivir treatment during the admission. Conclusions: Many patients with mild to moderate COVID-19 required the therapeutic intervention of remdesivir during the fourth pandemic period in Wakayama, Japan. From the clinical data obtained at admission, these risk factors could contribute to a prediction regarding the requirement of remdesivir treatment in cases of mild to moderate COVID-19.

O cão como coterapeuta e os cuidados para a sua atuação em ambiente hospitalar

Este estudo teve por objetivo abordar a cinoterapia como modalidade terapêutica capaz de promover uma maior humanização do atendimento ao doente, atuando como ferramenta efetiva no tratamento do assistido, dando ênfase aos cuidados necessários para o emprego do cão no ambiente hospitalar. A humanização da saúde, hoje já bem discutida, apoia iniciativas que visem à transformação do ambiente hospitalar. Acredita-se que, através de pequenas ações, podemos amenizar a dor de muitos, contribuir para o sucesso dos tratamentos e para a diminuição do tempo de hospitalização. A Cinoterapia, apoiada por uma equipe multidisciplinar, tem assistido crianças e adultos hospitalizados por diferentes patologias, pacientes cardíacos, psiquiátricos, portadores de Alzheimer, Parkinson, AIDS, paralisia cerebral, acidente vascular cerebral, câncer entre outras. Mesmo diante da tendência mundial e do reconhecimento da importância da terapia, a implantação de projetos ainda tem sido dificultada pela carência de estudos que demonstrem o impacto do cão no ambiente hospitalar. O desconhecimento dos riscos inerentes à terapia, principalmente no que diz respeito à transmissão de doenças, assim como a falta de protocolos com normas específicas para a sua implantação, são alguns dos entraves para uma maior disseminação da técnica. The aim of this study was to approach Pet therapy as a therapeutic modality capable of promoting a greater humanization of patient care, acting as an effective tool in the treatment of the assisted, emphasizing the necessary care for the use of the dog in the hospital environment. The humanization of health, now well discussed, supports initiatives aimed at transforming the hospital environment. It is believed that, through small actions, we can ease the pain of many, contribute to the success of the treatments and decrease the length of hospitalization. Pet therapy, supported by a multidisciplinary team, has assisted children and adults hospitalized for different pathologies, cardiac patients, psychiatric patients with Alzheimer's, Parkinson's, AIDS, cerebral palsy, stroke, cancer, among others. Even in the face of the worldwide trend and recognition of the importance of therapy, the implementation of projects has still been hampered by the lack of studies that demonstrate the impact of the dog in the hospital environment. The lack of knowledge about the risks inherent to the therapy, especially regarding the transmission of diseases, as well as the lack of protocols with specific norms for its implantation, are some of the obstacles for a greater dissemination of the technique.

Meta-analysis of COVID-19 patients to understand the key predictors of mortality in the non-vaccinated groups in remote settings

Various studies have looked into the impact of the COVID-19 vaccine on large populations. However, very few studies have looked into the remote setting of hospitals where vaccination is challenging due to social structure, myths, and misconceptions. There is a consensus that elevated inflammatory markers such as CRP, ferritin, D-dimer correlate with increased severity of COVID-19 and are associated with worse outcomes. In the present study, through retrospective meta-analysis, we have looked into ~20 months of SARS-COV2 infected patients with known mortality status and identified predictors of mortality concerning their comorbidities, various clinical parameters, inflammatory markers, superimposed infections, length of hospitalization, length of mechanical ventilation and ICU stay. Studies with larger sample sizes have covered the outcomes through epidemiological, social, and survey-based analysis; however, most studies cover larger cohorts from tertiary medical centers. In the present study, we assessed the outcome of non-vaccinated COVID 19 patients in a remote setting for 20 months from January 1, 2020, to August 30, 2021, at CHI Mercy Health in Roseburg, Oregon. We also included two vaccinated patients from September 2021 to add to the power of our cohort. The study will provide a comprehensive methodology and deep insight into multi-dimensional data in the unvaccinated group, translational biomarkers of mortality, and state-of-art to conduct such studies in various remote hospitals.

A Covid -19 Virtual Ward Model: A Preliminary Retrospective Clinical Evaluation From a UK District General Hospital

Objective: This study aims to evaluate the safety, utilization, ability to reduce length of hospitalization and overall outcomes of a COVID-19 virtual ward providing ongoing treatment at home. Method: A retrospective single-center study of patients discharged to the COVID-19 virtual “step down” ward between January 27th 2021 and March 2nd 2021. The referral process, length of hospitalization, length of stay on the virtual ward, readmissions, and ongoing treatment requirements including supplemental oxygen, antibiotics, and/or steroids were all noted. Results: A total of 50 patients were referred to the virtual ward. 43 referrals were accepted, 39 of which were from the respiratory ward. Four patients were readmitted, all due to hypoxia. All readmissions occurred within 5 days of discharge. 72% (n = 31) were discharged home with an ongoing oxygen requirement. 14.3% of patients were discharged with antibiotics only, 9.5% with steroids only and 23.8% with both antibiotics and steroids. The mean length of hospital stay for patients discharged to the virtual ward was 10.3 ± 9.7 days and 11.9 ± 11.6 days for all covid positive patients during this time. On average, patients spent 13.7 ± 7.3 days on the virtual ward. The average number of days spent on oxygen on the virtual ward was 11.6 ± 6.0 days. Conclusion: The virtual ward model exemplifies the potential benefits of collaborative working between primary and secondary care services, relieving pressure on hospitals whilst providing ongoing treatments at home such as supplemental oxygen. It also facilitates an early supported discharge of clinically stable patients with an improving clinical trajectory by managing them in the community.

Effect of Minimally Invasive Puncture Drainage and Conservative Treatment on Prognosis of Patients with Cerebral Hemorrhage

The objective of this study was to explore the effect of minimally invasive puncture drainage under unsupervised learning algorithm and conservative treatment on the prognosis of patients with cerebral hemorrhage. Fifty patients with cerebral hemorrhage were selected as the research objects. The CT images of patients were segmented by unsupervised learning algorithm, and the application value of unsupervised learning algorithm on CT images of patients with cerebral hemorrhage was evaluated. According to the treatment wishes of the patients themselves and their authorizers, they were divided into 30 patients with cerebral hemorrhage in the minimally invasive group and 20 patients with cerebral hemorrhage in the conservative group. The incidence rate of complications of cerebral hemorrhage, the length of hospitalization of the two groups, hematoma volume at admission, 3 days and 7 days after operation, and the hematoma dissipation rate on the 3rd and 7th day after operation were used as the evaluation index of therapeutic effect. MRS and ADL scores were used as prognostic indicators. The results show that K-means clustering algorithm has high quality and short time for CT image segmentation. The overall incidence rate of complications in minimally invasive group was 10%, lower than that in conservative group (25%) ( P < 0.05 ), and the length of hospitalization in minimally invasive group was longer than that in conservative group ( P < 0.05 ). The hematoma volume of minimally invasive group was 16.5 ± 2.4 mL on the 3rd day after operation, and that of conservative group was 27.4 ± 1.8 mL. There was significant difference between the two groups ( P < 0.05 ). In addition, CT showed that the hematoma reduction degree of minimally invasive group was higher than that of conservative group, and the hematoma dissipation rate was higher than that of conservative group on the 3rd and 7th day ( P < 0.05 ). The good MRS score in minimally invasive group was 3.15 times that in conservative group, and the good ADL score was 1.6 times that in conservative group, and there was significant difference in the total score between the two groups ( P < 0.05 ). Minimally invasive puncture drainage is better than conservative treatment in the clearance of hematoma, which is conducive to the recovery of neurological function and daily life of patients with cerebral hemorrhage and is of great help to the prognosis of patients.

A Meta-analysis on the Effect of Kangaroo Mother Care on Preterm Mortality

Background. Kangaroo mother care (KMC) is a low-cost but high-impact intervention for preterm and low birth weight (LBW) infants. Objectives. To determine the effect of KMC on in-hospital mortality among preterm and LBW infants, taking into consideration their gestational age, birth weight, income category of the country of birth, and medical stability. Materials and Methods. A comprehensive search of several databases, as well as local listings of research papers, was performed to look for randomized controlled studies with KMC as intervention, and mortality and length of hospitalization as outcome measures. The risk of bias and publication bias was assessed. We did subgroup analyses based on income category of the country of birth, gestational age, birth weight, and medical stability of the infants. Results. Sixteen randomized controlled trials (RCTs) with 1738 infants in the KMC group and 1674 infants in the control group were included. Based on the GRADE approach, although all the studies were RCTs, the evidence is assessed as moderate certainty due to the nature of the intervention (KMC) that prevented blinding. There was a 41% reduction in risk of dying among preterm and low birth weight infants who received KMC compared to conventional medical care (3.86%% vs 6.87%; RR = 0.59, 95% CI 0.44, 0.79; I2 = 0%; number needed to treat for additional benefit (NNTB) = 34; 16 RCTs; 3,412 infants). Furthermore, there were also reductions in the risk of dying among infants who were <34 weeks AOG (KMC: 4.32% vs CMC: 8.17%, RR = 0.55, 95% CI 0.38, 0.79; I2 = 0%; NNTB = 26; 10 RCTs; 1795 infants), with birthweight of >1500 g (KMC: 3.97% vs CMC: 6.83%, RR = 0.60; 95% CI 0.45, 0.82; I2 = 0%; NNTB = 35; 10 RCTs; 2960 infants), and born in low- and middle income countries (LMIC) (3.77% vs 6.95%; RR = 0.57, 95% CI 0.43, 0.77; I2 = 0%; NNTB = 32; 14 RCTs; 3281 infants). There was a significant reduction in mortality (KMC: 11.05% vs CMC: 20.94%; RR = 0.54; 95% CI 0.34, 0.87; I2 = 0%; NNTB = 11; 5 RCTs; 387 infants) even among medically unstable infants who received KMC compared to those who did not. The length of hospitalization did not significantly differ between the KMC and the control groups. Due to high heterogeneity, subgroup analyses were performed, which showed a trend towards a shorter length of hospital stay among preterm infants <34 weeks AOG, with birthweight ≥1500 g, medically unstable during admission, and belonging to LMIC but did not reach statistical significance. Conclusion. There was moderate certainty evidence that KMC can decrease mortality among preterm and LBW infants. Furthermore, KMC was beneficial among relatively more premature, bigger, medically unstable preterm infants and born in low to middle-income countries.

Cumulative Effective Dose from Medical Imaging in Inflammatory Bowel Disease

Inflammatory bowel diseases (IBD) are chronic and relapsing disorders usually requiring numerous medical imaging. IBD patients might be exposed to a large dose of radiation. As a cumulative effective dose (CED) ≥ 50 mSv is considered significant for stochastic risks of cancer, it is important to monitor the radiation exposure of IBD patients. In the present work, we aimed to quantify the mean CED in IBD patients and identify factors associated with exposure to high doses of diagnostic radiation. A retrospective chart view of patients with IBD hospitalized between 2015 and 2019 was performed. A total of 65 patients with Crohn’s disease (CD) and 98 patients with ulcerative colitis (UC) were selected. Of all imaging studies performed, 73% were with doses of ionizing radiation. Mean CED (SD) amounted to 19.20 (15.64) millisieverts (mSv) and 6.66 (12.39) mSv, respectively, in patients with CD and UC (p < 0.00001). Only 1.84% of the patients received CED ≥ 50 mSv. We identified three factors associated with CED in the IBD patients: number of surgical procedures, and number and length of hospitalization. CD patients with strictures or penetrating disease and UC patients with extensive colitis were more likely to receive higher radiation doses.

Eleven-year Retrospective Study Characterizing Patients With Severe Brain Damage and Poor Neurological Prognosis -Role of Physicians’ Attitude Toward Life-Sustaining Treatment

BackgroundSevere brain hemorrhage/infarction and cardiac arrest constitute the most critical situations leading to poor neurological prognosis. Characterization of these patients is required to offer successful end-of-life care, but actual practice is affected by multiple confounding factors, including ethicolegal issues, particular in Japan and Asia. The aim of this study is to evaluate the clinical courses of patients with severe brain damage and to assess the preference of end-of-life care for these patients in Japanese hospitals.MethodsA retrospective observational study was conducted between 2008 and 2018. All intracranial hemorrhage/infarction and cardiac arrest out-patients (n=510) who were admitted to our two affiliated hospitals and survived but with poor neurologic outcomes were included. Demographic characteristics as well as prognosis and treatment policies were also assessed. Results Patients were divided into two categories; cases with absent brainstem reflex (BSR) (BSR[-]) and those with preserved BSR (BSR[+]). The survival rate was higher and the length of hospitalization was longer in patients with BSR[+] than in those with BSR[-]. Among three life-sustaining policies (i.e., aggressive treatment, withdrawal of treatment, and withholding of treatment), withholding of treatment was adopted to most patients. In BSR[-], the proportion of three treatment policies performed at the final decision did not differ from that at the initial diagnosis on neurological status (p=0.432). In contrast, this proportion tended to be altered in BSR[+] (p=0.072), with a decreasing tendency of aggressive treatment and a modest increasing tendency of withdrawal of treatment. Furthermore, the requests from patients’ families to withdraw life-sustaining treatment, including discontinuation of mechanical ventilation, increased, but actual implementation of withdrawal by physicians was less than half of the requests. ConclusionsBSR constitutes a crucial determinant of mortality and length of hospitalization in comatose patients with severe brain damage. Although the number of withdrawal of life-sustaining treatment tends to increase over time in BSR[+] patients, there are many more requests from patients’ families for withdrawal. Since physicians has a tendency to desist from withdrawing life-sustaining treatment, more in-depth communication between medical staff and patients’ families will facilitate mutual understanding over ethicolegal and religious issues and may thus improve end-of-life care.

Predictors of Rehospitalization and Mortality in Diabetes-Related Hospital Admissions

The risk factors of rehospitalization and death post-discharge in diabetes-related hospital admissions are not fully understood. To determine them, a population-based retrospective epidemiological survey was performed on diabetes-related admissions from the Polish national database. Logistic regression models were used, in which the dependent variables were rehospitalization due to diabetes complications and death within 90 days after the index hospitalization. In 2017, there were 74,248 hospitalizations related to diabetes. A total of 11.3% ended with readmission. Risk factors for rehospitalization were as follows: age < 35 years; male sex; prior hospitalization due to acute diabetic complications; weight loss; peripheral artery disease; iron deficiency anemia; kidney failure; alcohol abuse; heart failure; urgent, emergency, or weekend admission; length of hospitalization; and hospitalization in a teaching hospital with an endocrinology/diabetology unit. Furthermore, 7.3% of hospitalizations resulted in death within 90 days following discharge. Risk factors for death were as follows: age; neoplastic disease with/without metastases; weight loss; coagulopathy; alcohol abuse; acute diabetes complications; heart failure; kidney failure; iron deficiency anemia; peripheral artery disease; fluid, electrolytes, and acid–base balance disturbances; urgent or emergency and weekend admission; and length of hospitalization. We concluded that of all investigated factors, only hospitalization within an experienced specialist center may reduce the frequency of the assessed outcomes.
