Admission Groups and Academic Performance: A Study of Marginal Entrants in the Selection to Higher Education

The purpose of this paper is to study whether Swedish admission policies successful in selecting the best-performing students. The Swedish universities select students based on two different instruments, which each form a separate admission group. A regression model is recommended to estimate the achievement differences for the marginally accepted students between the admission groups and is applied to a sample of 9024 Swedish university entrants in four different fields of education. Marginally accepted students in the group selected by school grades on average perform better than students accepted by an admission test, suggesting that a small reallocation of study positions towards the grade admission group may increase overall academic achievement. However, the achievement difference appears to vary concerning university programme selectivity. We found that increasing selection by grades in less competitive programmes would improve overall achievement, while we do not find any effect for highly competitive programmes.

Inpatient Outcomes Following a Return Visit to the Emergency Department: A Nationwide Cohort Study

Introduction: Emergency department (ED) revisits are traditionally used to measure potential lapses in emergency care. However, recent studies on in-hospital outcomes following ED revisits have begun to challenge this notion. We aimed to examine inpatient outcomes and resource use among patients who were hospitalized following a return visit to the ED using a national database. Methods: This was a retrospective cohort study using the National Health Insurance Research Database in Taiwan. One-third of ED visits from 2012–2013 were randomly selected and their subsequent hospitalizations included. We analyzed the inpatient outcomes (mortality and intensive care unit [ICU] admission) and resource use (length of stay [LOS] and costs). Comparisons were made between patients who were hospitalized after a return visit to the ED and those who were hospitalized during the index ED visit. Results: Of the 3,019,416 index ED visits, 477,326 patients (16%) were directly admitted to the hospital. Among the 2,504,972 patients who were discharged during the index ED visit, 229,059 (9.1%) returned to the ED within three days. Of them, 37,118 (16%) were hospitalized. In multivariable analyses, the inpatient mortality rates and hospital LOS were similar between the two groups. Compared with the direct-admission group, the return-admission group had a lower ICU admission rate (adjusted odds ratio, 0.78; 95% confidence interval [CI], 0.72-0.84), and lower costs (adjusted difference, -5,198 New Taiwan dollars, 95% CI, -6,224 to -4,172). Conclusion: Patients who were hospitalized after a return visit to the ED had a lower ICU admission rate and lower costs, compared to those who were directly admitted. Our findings suggest that ED revisits do not necessarily translate to poor initial care and that subsequent inpatient outcomes should also be considered for better assessment.

Features of Patients Receiving Extracorporeal Membrane Oxygenation Relative to Cardiogenic Shock Onset: A Single-Centre Experience

Background and Objectives: Extracorporeal membrane oxygenation (ECMO) can be helpful in patients with cardiogenic shock associated with myocardial infarction, and its early use can improve the patient survival rate. In this study, we report a mortality rate-difference analysis that examined the time and location of shock occurrence. Materials and Methods: We enrolled patients who underwent ECMO due to cardiogenic shock related to myocardial infarction and assigned them to either a pre- or post-admission shock group. The primary outcome was the 1-month mortality rate; a subgroup analysis was conducted to assess the effect of bailout ECMO. Results: Of the 113 patients enrolled, 67 (38 with pre-admission shock, 29 with post-admission shock) were analysed. Asystole was more frequently detected in the pre-admission shock group than in the post-admission group. In both groups, the commonest culprit lesion location was in the left anterior descending artery. Cardiopulmonary resuscitation was performed significantly more frequently and earlier in the pre-admission group. The 1-month mortality rate was significantly lower in the pre-admission group than in the post-admission group. Male sex and ECMO duration (≥6 days) were factors significantly related to the reduced mortality rate in the pre-admission group. In the subgroup analysis, the mortality rate was lower in patients receiving bailout ECMO than in those not receiving it; the difference was not statistically significant. Conclusions: ECMO application resulted in lower short-term mortality rate among patients with out-of-hospital cardiogenic shock onset than with in-hospital shock onset; early cardiopulmonary resuscitation and ECMO might be helpful in select patients.

The Role of Therapeutic Plasma Exchange (TPE) in Multisystem Inflammatory Syndrome in Children (MIS-C)

Multisystemic inflammatory syndrome in children (MIS-C) is a new potentially life-threatening disease that is related to coronavirus disease 2019 (COVID-19). The aim of this study is to reveal the clinical and laboratory results of MIS-C and the role of therapeutic plasma exchange (TPE) in its treatment. Clinical, laboratory and radiological characteristics of the patients who were admitted to the pediatric ward and pediatric intensive care unit (PICU) of a tertiary hospital with a diagnosis of MIS-C between April 2020 and March 2021 were included in the study. Forty-one patients were admitted to our hospital with a diagnosis of MIS-C. Twenty-one (51.2%) patients were admitted to the PICU. Six patients needed invasive mechanical ventilation (14.6%), 10 patients (24.4%) TPE and 3 patients (7.3%) needed extracorporeal membrane oxygenation (ECMO). The patients were grouped according to need for PICU admission (Group 1: no need for PICU, Group 2: need for PICU admission). Group 2 had significantly higher levels of C-reactive protein (CRP), alanine aminotransferase (ALT), ferritin, D-dimer, pro-B type natriuretic peptide (pro BNP) and lactate (p < 0.05). Hyponatremia found to be an independent risk factor for inpatient MIS-C in the PICU. We think that dynamic laboratory trending is beneficial in determining the need for PICU admission and TPE may be effective in critically ill patients.

Efficacy of Korean Medicine Combination Treatment on Recurrent Neck Pain After Medical Procedures: A Retrospective Study

Background: The aim of this study was to evaluate the efficacy of Korean medicine combination treatment on recurrent neck pain after medical procedures.Methods: This retrospective study included 158 inpatients of the Daejeon Jaseng Hospital of Korean Medicine who were diagnosed with “Cervical disc disorder with radiculopathy (M50.1)” between December 14^th, 2017 and May 29^th, 2019. The patients were assigned to 1 of 2 groups based on whether they received medical procedures on the cervical spine at least once. Korean medicine combination treatment was evaluated using EuroQol-5 dimensions index (EQ-5D), numeric rating scale (NRS), and neck disability index (NDI) scores.Results: Before and after treatment, the patients who received medical procedures on the cervical spine at least once before admission (Group A) showed a statistically significant difference in the NDI and NRS scores but not in the EQ-5D scores. This was similar to the patients who had not received medical procedures on the cervical spine before admission (Group B) they showed a statistically significant difference in the NDI and NRS scores but not in the EQ-5D scores. When comparing the results of Group A and Group B before and after treatment, no statistically significant differences were observed in the EQ-5D, NDI, and NRS scores.Conclusion: Korean medicine combination treatment improves the neck functional disability of patients who suffer from recurrent neck pain despite patients having undergone medical procedures.

Hyperglycemia at admission is a strong predictor of mortality and severe/critical complications in COVID-19 patients: a meta-analysis

Background: Hyperglycemia at admission has been demonstrated to exacerbate the outcomes of coronavirus disease 2019 (COVID-19) but a meta-analysis is lacking to further confirm this hypothesis. The purpose of this meta-analysis was to summarize the evidence on the association between hyperglycemia at admission and the development of COVID-19. Method: Four databases namely, PubMed, Web of Science, Embase and Cochrane Library, were screened for eligible studies. STATA software was utilized to pool data for this meta-analysis. The primary outcomes included mortality and severity. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated with random-effects models, and the quality of evidence was appraised by the Newcastle–Ottawa Scale (NOS). This meta-analysis was prospectively registered online on PROSPERO, CRD42020191763. Results: Sixteen observational studies with 6386 COVID-19 patients relating hyperglycemia at admission to COVID-19 outcomes were included. The overall data demonstrated that, compared with the control, the hyperglycemia at admission group was more likely to have increased mortality (OR = 3.45, 95% CI, 2.26–5.26) and severe/critical complications (OR = 2.08, 95% CI, 1.45–2.99) of COVID-19. Conclusion: Hyperglycemia at admission in COVID-19 patients may be a strong predictor of mortality and complications.

Efficiency of prognostic scales in assessing patients' condition in severe acute pancreatitis

Objectives to compare the predictive efficiency of modern scales used in prognosis of disease severity (APACHE II, SAPS, SOFA, MODS) in patients with severe acute pancreatitis. Material and methods.17 patients formed two study groups: Group 1 consisted of 10 survived patients, Group 2 included 7 patients with a fatal outcome. The mortality ratio and the severity of the condition were calculated for all 17 patients, using the scales presented above, at the admission to the ICU and at the moment of transfer to a surgical department. The intensive care procedure and surgical interventions were in line with the clinical recommendations for surgical treatment of severe acute pancreatitis. Results.The day of ICU admission, Group 1, the average mortality rate on the SAPS scale was 110.08%; on the SOFA scale 270.08%; on the MODS scale 12%; on the APACHE II scale 8.450.09%. The day of ICU admission, Group 2, the average mortality rate on the SAPS scale was 5.77.11%; on the SOFA scale 25.146.09%; on the MODS scale 2.41.05%; on the APACHE II scale 12.18.49%. The day of patients' transfer from the ICU to the surgical department, Group1, the average mortality rate on the SAPS scale was 8.990.10%; on the SOFA scale 300.15%; on the MODS scale 12%; on the APACHE II scale 14.290.08%. The day of patients' transfer from the ICU to the surgical department, Group 2, the average mortality rate on the SAPS scale was 7.78.69%; on the SOFA scale 220%; on the MODS scale 12%, on the APACHE II scale 12.379.89%. According to our data, none of the used prognostic scales could present the real condition of a patient or the mortality prognosis for patients in both groups. By comparison of the average mortality rate calculated for patients of Group 1 and Group 2, we revealed the more unfavorable prognosis for the survived patients than for the patients with lethal outcome. Conclusion.The objective evaluation of the severity of patient's condition and the prognosis for treatment is not possible with the scales used in the study. Among them, the SAPS and APACHE II scales provided the most precise prognoses for patients' condition.

Clinical findings of 35 cases with novel coronavirus pneumonia outside of Wuhan

Objective: We sought to investigate the clinical characteristics of patients with novel coronavirus pneumonia in Xiamen, which is a city in Fujian Province, China. Methods: From January 20, 2020, to March 4, 2020, the clinical characteristics of all patients confirmed with novel coronavirus pneumonia admitted to the First Affiliated Hospital of Xiamen University, which was the only designated hospital for cases of novel coronavirus pneumonia in Xiamen, were analyzed. Results: A total of 35 cases of novel coronavirus pneumonia were confirmed. Patients were divided into the general-ward admission group and the intensive-care-unit (ICU) admission group. The most commonly observed symptoms were fever (80%), cough (51%), expectoration (28%), and fatigue (23%). Compared with patients in the general-ward group, patients in the ICU group had a higher maximum body temperature, a longer duration of fever after admission, and more symptoms of systemic pain. Considering the laboratory findings, patients in the ICU group exhibited lower peripheral blood lymphocyte ratios and lymphocyte counts but higher C-reactive protein and lactate dehydrogenase levels. All patients were discharged without death, and no patients required invasive ventilation, continuous renal replacement therapy, or extracorporeal membrane oxygenation. Conclusion: Relative to patients with novel coronavirus pneumonia in Wuhan, the cases in Xiamen were less severe.

The implications of platelet count changes during hospitalization in the disease management of pediatric patients with bronchiolitis

Background: The clinical implications of platelet count changes in patients with bronchiolitis throughout hospitalization have not been extensively investigated. We aimed to investigate the significance of platelet count on admission and platelet count changes during hospitalization in pediatric patients with bronchiolitis. Methods: Clinical data from 559 consecutive patients hospitalized for bronchiolitis were collected and compared after grouping according to the platelet count on admission and the delta platelet count during hospitalization (the platelet count on discharge minus the platelet count on admission; Group A, delta platelet count ≤ -50 × 109/L; Group B, -50 × 109/L < delta platelet count ≤ 50 × 109/L; Group C, delta platelet count > 50 × 109/L). Results: Thrombocytosis was found in 122 (21.8%) patients, while 437 (78.2%) patients had a normal platelet count on admission. There was no difference in disease severity between these two groups. Groups A, B, and C comprised 79 (14.1%), 179 (32.0%), and 301 (53.9%) patients, respectively. The patients from Group A had a higher platelet count on admission, a lower platelet count on discharge, and a longer hospitalization duration. These patients had a lower concentration of C-reactive protein, longer periods of oxygen therapy and stay in the pediatric intensive care unit (PICU), and a greater frequency of mechanical ventilation than the patients from Group B or Group C. Notably, among all the patients, the delta platelet count [63 (-3–142) × 109/L] negatively correlated with the numbers of days of oxygen therapy [4.0 (3.0–6.0), day] (r = -0.186, P = 0.027) and stay in the PICU [5.0 (3.0–6.0), day] (r = -0.391, P = 0.001). Conclusions: Repeated assessment of platelet count during hospitalization in pediatric patients with bronchiolitis may provide useful information for disease management.
