The relationship of domestic pet ownership with the risk of childhood asthma: A systematic review and meta-analysis

BACKGROUND AND OBJECTIVE

The relationship between pet ownership and childhood asthma remains controversial. In recent years, there have been increasing studies with large sample size. Therefore, we conducted this systematic review and meta-analysis to evaluate the relationship between pet ownership and childhood asthma.

METHOD

Relevant research was retrieved from PubMed, Cochrane, EMBASE, and Web of science. The retrieval was as of October 1, 2021. The Newcastle-Ottawa Scale (NOS) was used to assess the quality of the included studies. Stata 15.0 was used to conduct the meta-analysis.

RESULTS

A total of 60 studies with large sample size published between 1995 and 2021 were included in this systematic review and meta-analysis, which included 18 cohort studies and 42 case-control studies covering 27 countries and 1,871,295 children. As shown by meta-analysis results, cat ownership (OR = 1.18, 95%CI: 1.05∼1.33) and dog ownership (OR = 1.12, 95%CI: 1.0 0∼1.24) have a significant bearing on the occurrence of childhood asthma. Pet ownership was also positively correlated with the occurrence of severe childhood asthma (OR = 1.15, 95%CI: 1.11∼1.20).

CONCLUSION

Pet ownership, especially cats and dogs, is associated with the occurrence of asthma in children.

Short-term effectiveness of baricitinib in children with refractory and/or severe juvenile dermatomyositis

OBJECTIVE

To determine the short-term effectiveness safety of baricitinib in children with refractory and/or severe juvenile dermatomyositis (rsJDM) in a real-world setting.

METHODS

This was a single-center retrospective study, including 20 children with rsJDM. They were all treated using baricitinib combined with steroids and other immunosuppressive agents. The childhood myositis assessment scale (CMAS) and PRINTO remission criteria were used to evaluate the disease severity and treatment outcome at 0, 4, 12, and 24 weeks after initiation of baricitinib.

RESULTS

The skin rash improved in 95% of patients (19/20) at week 24, with a significant decrease of skin-DAS at weeks 12 (6.0 vs. 2.0, p < 0.05] and week 24 [6.0 vs. 1.0, p < 0.05) by median statistics. The CMAS score increased significantly at week 12 (41.0 [29.0, 44.0] vs. 46.0 [42.0, 52.0], p < 0.05) and week 24 (41.0 [29.0, 44.0] vs. 50.0 [45.0, 52.0], p < 0.05), as did the manual muscle testing (MMT)-8 score at week 24 (73.0 [610, 76.0] vs. 79.0 [77.0, 80.0], p < 0.05). At 24 weeks, the complete response (CR) and partial response (PR) were achieved in 75% (15/20) and 15% (3/20), respectively. The dose of corticosteroids (CS) decreased by 37% from the baseline (0.53 [0.42, 1.00] mg/kg) to week 12 (0.33 [0.18, 0.40] mg/kg) (p < 0.05), and by 49% at week 24 (p < 0.05). No serious side effects were observed.

CONCLUSION

Baricitinib combined with traditional immunosuppressants treatment was efficacious in rsJDM. Add-on therapy of baricitinib was helpful for tapering CS dose. No serious side effects were observed in this study.

Development and validation of a nomogram for predicting acute kidney injury after orthotopic liver transplantation

BACKGROUND

We aim to develop and validate a nomogram model for predicting severe acute kidney injury (AKI) after orthotopic liver transplantation (OLT).

METHODS

A total of 576 patients who received OLT in our center were enrolled. They were assigned to the development and validation cohort according to the time of inclusion. Univariable and multivariable logistic regression using the forward variable selection routine were applied to find risk factors for post-OLT severe AKI. Based on the results of multivariable analysis, a nomogram was developed and validated. Patients were followed up to assess the long-term mortality and development of chronic kidney disease (CKD).

RESULTS

Overall, 35.9% of patients were diagnosed with severe AKI. Multivariable logistic regression analysis revealed that recipients' BMI (OR 1.10, 95% CI 1.04-1.17, p = 0.012), hypertension (OR 2.32, 95% CI 1.22-4.45, p = 0.010), preoperative serum creatine (sCr) (OR 0.96, 95% CI 0.95-0.97, p < 0.001), and intraoperative fresh frozen plasm (FFP) transfusion (OR for each 1000 ml increase 1.34, 95% CI 1.03-1.75, p = 0.031) were independent risk factors for post-OLT severe AKI. They were all incorporated into the nomogram. The area under the ROC curve (AUC) was 0.73 (p < 0.05) and 0.81 (p < 0.05) in the development and validation cohort. The calibration curve demonstrated the predicted probabilities of severe AKI agreed with the observed probabilities (p > 0.05). Kaplan-Meier survival analysis showed that patients in the high-risk group stratified by the nomogram suffered significantly poorer long-term survival than the low-risk group (HR 1.92, p < 0.01). The cumulative risk of CKD was higher in the severe AKI group than no severe AKI group after competitive risk analysis (HR 1.48, p < 0.05).

CONCLUSIONS

With excellent predictive abilities, the nomogram may be a simple and reliable tool to identify patients at high risk for severe AKI and poor long-term prognosis after OLT.

Critical illness related to community acquired pneumonia, its epidemiology and outcomes in a pediatric intensive care unit of Pakistan

BACKGROUND

To determine the epidemiology and outcomes in critically ill children admitted with severe community acquired pneumonia (CAP) and to identify risk factors associated with mortality in a pediatric intensive care unit (PICU) METHODS: Retrospective review of medical records of all children (age 1 month to 18 years) admitted to PICU with CAP from January 2013 to March 2018 was done. Patients admitted in last 2 weeks before current illness and those with bronchiolitis (based on clinical diagnosis) were excluded. Data were collected on a structured proforma and included demographic, clinical data, comorbidities, therapeutic information, laboratory data, and outcome data. Results were presented as mean with SD and frequency with percentages. Factors associated with mortality were analyzed, using logistic regression for both univariate and multivariate analyses.

RESULTS

A total of 187 children with severe CAP were identified, 53.5% (n = 100) were <1 year of age and 65.2% (n = 122) were male, 32.6% (n = 61) were underweight, and 24.6% (n = 46) were stunted. A total of 94% (175) required mechanical ventilation. Mortality among the cohort was 20.3% (n = 38) with median length of mechanical ventilation 4 (2-8) days, and median length of PICU stay was 6 (4-12) days. PRISM score >10 on admission, presence of systemic illness, empyema, and length of PICU stay 14 (±2) days were associated with increased mortality among critically ill children admitted with CAP (p < .05).

CONCLUSIONS

Severe illness on presentation, presence of systemic illness and empyema are associated with increased mortality in children admitted to the PICU with severe CAP.

Use of Low-Molecular-Weight Heparin and Peak anti-Xa Monitoring In Severe SARS-CoV-2 Disease: A Brief Report

In 2019, a novel coronavirus was identified in Wuhan, China. This strain was classified as a pandemic in early 2020 by the World Health Organization (WHO), rapidly reaching millions of cases worldwide and overwhelming intensive care units. One distinct feature identified in severe SARS-CoV-2 is abnormal and complex coagulation and hematologic abnormalities, including significantly elevated D-dimer and fibrin/fibrinogen values possibly increasing morbidity and mortality in this patient population. Aggressive anticoagulation therapy with appropriate peak anti-Xa level monitoring has produce satisfactory results at our institution. Our intent is to present a case series of our strategy to highlight the benefits of this approach.

Severe cases of osteogenesis imperfecta type VIII due to a homozygous mutation in P3H1 (LEPRE1) and review of the literature

BACKGROUND

Osteogenesis imperfecta (OI) is a genetic disorder that causes skeletal fragility, multiple fractures and several extraskeletal disorders. Most cases of OI are caused by mutations in COL1A1/A2. Osteogenesis imperfecta type VIII typically causes a severe and fatal phenotype that presents at birth with severe osteopenia, congenital fractures and other clinical manifestations.

OBJECTIVES

We describe the cases of an 11-year-old female and a 9-year-old male with homozygous truncating mutations in P3H1. Both cases were born with intrauterine fractures and suffered multiple fractures shortly after birth, requiring multiple operations to correct both fractures and severe scoliosis. The patients have been treated with pamidronate since the age of 2.

MATERIAL AND METHODS

Whole exome sequencing (WES) was performed by Gene by Gene using Twist Bioscience technology. Initially, ~36.5 Mb of consensus coding sequences (targeting >98% of RefSeq and Gencode v. 28 regions obtained from the human genome) was replicated from fragmented genomic DNA using the Twist Human Core Exome Plus kit. The subsequent library was sequenced on the Illumina Novaseq Next Generation Sequencing platform to achieve at least ×20 reading depth for >98% of the targeted bases. Variant annotations and filtering was performed using Ingenuity Variant Analysis software.

RESULTS

We identified a homozygous mutation in the 3rd exon of P3H1 (c.628C>T/p.Arg210 Ter). Our cases broaden the phenotypic spectrum of OI type VIII as, to the best of our knowledge, these are the first postnatal cases with P3H1 (c.628C>T/p.Arg210 Ter) mutations published in the literature.

CONCLUSIONS

We present the first recorded postnatal cases from unrelated families of OI type VIII, broadening our understanding of the severe, but nonfatal spectrum of clinical phenotype of this recessive form of OI.

Correlation Between CT Severity Scoring and Diabetes Mellitus in Patients With COVID-19 Infection

Background and objective

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), was first identified in Wuhan, China in December 2019. Since then, It has spread across multiple countries and was declared a pandemic by WHO in March 2020. Patients with underlying diabetes mellitus (DM) are deemed at-risk for developing severe COVID-19 infection. In light of this, we aimed to evaluate the correlation between DM and chest CT severity scores (CTSS) in COVID-19 patients.

Methods

This was a hospital-based descriptive, analytical retrospective study conducted at our tertiary care hospital. A quantitative severity score was calculated among 220 patients with COVID-19 infection based on the degree of lung lobe involvement on CT chest scans. Based on CTSS, the patients were classified into groups of mild, moderate, and severe lung involvement. The association between DM and CTSS was evaluated using the chi-square test.

Results

The severity of lung involvement was higher among COVID-19 patients with a co-diagnosis of DM (29.3%) compared to those without DM (11.7%). This association of severe lung involvement with DM was statistically significant (p=0.002).

Conclusion

Based on our findings, diabetic patients are at an increased risk of developing the severe form of COVID-19 with a higher CT lung involvement score compared to non-diabetic patients.

Fibrosis-4 index and mortality in coronavirus disease 2019: a meta-analysis

BACKGROUND/AIMS

In this meta-analysis, we aimed to evaluate the prognostic value of fibrosis-4 index (FIB-4) in COVID-19.

METHODS

We performed a comprehensive literature search of PubMed, Embase, and Scopus databases on 26 November 2020. FIB-4 was calculated by [age (years) × AST (IU/L)]/[platelet count (109/L) × √ALT (U/L)]. A value above cutoff point was considered high and a value below cutoff point was considered low. The main outcome was mortality, the association between high FIB-4 and mortality was reported in odds ratio (OR). Sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic OR (DOR), area under the curve (AUC) were generated.

RESULTS

There were 963 patients from five studies included in this systematic review and meta-analysis. Meta-analysis showed that high FIB-4 was associated with increased mortality [OR 3.96 (2.16-7.27), P < 0.001; I2: 41.3%]. High FIB-4 was associated mortality with a sensitivity of 0.56 (0.40-0.70), specificity of 0.80 (0.72-0.86), PLR 2.8 (1.8-4.2), NLR 0.55 (0.39-0.78), DOR 5 (2-10), and AUC of 0.77 (0.73-0.81). Fagan's nomogram indicated that for a pre-test probability (mortality) of 30%, a high FIB-4 was associated with 54% post-test probability and a low FIB-4 was associated with 19%, respectively. The funnel-plot analysis was asymmetrical, trim-and-fill analysis by imputation of a study on the left side using linear estimator resulted in an OR of 3.48 (1.97-6.14). Egger's test showed no indication of small-study effects (P = 0.881).

CONCLUSION

High FIB-4 was associated with mortality in patients with COVID-19.

Extended Distal Chevron Osteotomy and Akin Osteotomy Using Bioabsorbable Materials for Treatment of Moderate to Severe Hallux Valgus

The purpose of this study was to investigate the suitability of bioabsorbable materials for fixation of extended distal chevron osteotomy and Akin osteotomy for the treatment of moderate to severe hallux valgus. We performed a retrospective analysis of extended distal chevron osteotomy and Akin osteotomy for the treatment of moderate to severe hallux valgus (33 patients, 42 feet). Fixation of extended distal chevron osteotomy and Akin osteotomy was performed using poly-l-lactic acid pins and polylactic acid/polyglycolic acid copolymer sutures, respectively. The radiological outcomes were evaluated based on the preoperative and 3-year follow-up intermetatarsal angle, hallux valgus angle, and hallux interphalangeal angle. The clinical results were assessed according to 3-year follow-up Manchester-Oxford Foot Questionnaire scores, patient satisfaction, and postoperative complications. All radiological and clinical results were compared with those of a control group treated with metallic implants. The mean 3-year follow-up intermetatarsal angle, hallux valgus angle, and hallux interphalangeal angle were significantly corrected from the preoperative values (all p < .001). The mean 3-year follow-up Manchester-Oxford Foot Questionnaire scores score was significantly improved from the preoperative values (p < .001). Regarding patient satisfaction, 88.1% of the patients reported good to excellent results. A total of seven complications were reported. All radiological and clinical results were comparable with those of control group treated with metallic implant. Based on these results, we recommend using bioabsorbable materials as another reliable device for fixation of extended distal chevron osteotomy and Akin osteotomy even for the treatment of moderate to severe hallux valgus.

Comparison of comorbidities among severe and non-severe COVID-19 patients in Asian versus non-Asian populations: A systematic review and meta-analysis

OBJECTIVES

This study aimed to evaluate the comorbidities among severe and non-severe COVID-19 patients in Asian versus non-Asian populations.

DESIGN

Systemic review and Meta-analysis.

METHODS

A systematic literature search was conducted using PubMed, Embase, Scopus and the web of science Database up to 24 March 2021. Odds ratios were calculated using a random-effects model.

RESULTS

We identified 66 studies including 39 Asian and 27 non-Asian studies. This study demonstrated that the proportion of hypertension was significantly higher in severe group than in non-severe group for Asian (OR = 2.46) and non-Asian (OR = 1.60, 95% CI: 1.37-1.86, I²  = 84%; p < .00001) patients. Similarly, the proportion of diabetes, cardiovascular disease and chronic kidney disease was significantly higher in severe group than in non-severe group for both Asian and non-Asian studies. We found no statistically significant difference between the severe versus non-severe group for cancer (OR = 1.26) and chronic obstructive pulmonary disease (OR = 1.32) among non-Asian patients.

Corticosteroids in Community-Acquired Pneumonia: A Review of Current Literature

Objective: To review the evidence and recommendations for the use of adjunctive corticosteroid therapy in community-acquired pneumonia (CAP). Data Sources: A literature search was conducted using PubMed (1993 to November 2020) using the search terms corticosteroids AND community-acquired pneumonia. Study Selection and Data Extraction: Pertinent randomized controlled trials, systematic reviews, and meta-analyses assessing the efficacy and safety of adjunctive corticosteroids in patients with pneumonia were evaluated for inclusion. Data Synthesis: Studies suggest that corticosteroids reduce time to clinical stability and length of hospital stay, but data regarding other important clinical outcomes, such as mortality, are limited. The greatest margin of benefit appears to be in patients with severe CAP. Evidence consistently demonstrates hyperglycemia as the most common adverse effect of corticosteroid therapy in CAP. Safety concerns regarding the potential impact of corticosteroids on the rate of CAP-related rehospitalizations require further investigation. Relevance to Patient Care and Clinical Practice: This review summarizes literature evaluating the efficacy and safety of adjunctive corticosteroids in patients with CAP. It also includes a discussion on current guideline recommendations, patient selection, corticosteroid regimens, adverse effect considerations, limitations, and future directions in this area of research. Conclusions: Studies reviewed suggest that corticosteroids are relatively beneficial and safe in patients with CAP, with the greatest benefit in severe CAP. Currently, the routine use of corticosteroids is not recommended by clinical practice guidelines with the exception of CAP and refractory septic shock. Further research is needed to better define the ideal role of corticosteroids in CAP.

Early IFN-α signatures and persistent dysfunction are distinguishing features of NK cells in severe COVID-19

Longitudinal analyses of the innate immune system, including the earliest time points, are essential to understand the immunopathogenesis and clinical course of coronavirus disease (COVID-19). Here, we performed a detailed characterization of natural killer (NK) cells in 205 patients (403 samples; days 2 to 41 after symptom onset) from four independent cohorts using single-cell transcriptomics and proteomics together with functional studies. We found elevated interferon (IFN)-α plasma levels in early severe COVD-19 alongside increased NK cell expression of IFN-stimulated genes (ISGs) and genes involved in IFN-α signaling, while upregulation of tumor necrosis factor (TNF)-induced genes was observed in moderate diseases. NK cells exert anti-SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) activity but are functionally impaired in severe COVID-19. Further, NK cell dysfunction may be relevant for the development of fibrotic lung disease in severe COVID-19, as NK cells exhibited impaired anti-fibrotic activity. Our study indicates preferential IFN-α and TNF responses in severe and moderate COVID-19, respectively, and associates a prolonged IFN-α-induced NK cell response with poorer disease outcome.

A Systematic Review of Surgical Techniques for Management of Severe Rhinophyma

Study Design

Systematic review of the literature.

Objective

The goal of this study is to review the current literature on severe rhinophyma requiring operative management for significant cosmetic deformity or nasal obstruction. We aim to provide a treatment algorithm for the various surgical techniques employed in the treatment of severe rhinophyma.

Methods

Independent searches of the PubMed and MEDLINE databases were performed. Articles from the period of 2010 to 2020 were collected. All studies which described surgical treatment of severe rhinophyma using the Boolean method and relevant search term combinations, including "rhinophyma," "severe," "operative" and "surgery" were collected.

Results

A total of 111 relevant unique articles met criteria for eligibility analysis. Of these, 85 articles were deemed inappropriate for the literature review due to exclusion criteria. The remaining 26 articles were included in the literature review. Due to variability in study design and outcome measures, formal synthesis of data in the form of a meta-analysis was not possible.

Conclusions

Severe rhinophyma may present a reconstructive challenge to reestablish normal contour and patent nasal airway. Significant deformity necessitates surgical correction. The present article reviews the current literature and provides a summary and stepwise explanation of established surgical techniques for addressing the cosmetic and functional deficits these patients encounter.

Factors Influencing the Severity of Acute Radiation-Induced Skin and Mucosal Toxicity in Head and Neck Cancer

Background and purpose

Radiotherapy is a crucial part of cancer therapy armamentarium, but it is associated with skin and mucosal toxicity in a substantial proportion of patients with head and neck cancer. Its extent, however, depends on several patient-related and treatment-related factors. In-depth knowledge of these is prudent for better patient management.

Aim

The aim of this study is to assess the factors influencing the severity of acute radiation-induced skin and mucosal toxicity in patients with head and neck cancer receiving external beam radiotherapy.

Materials and methods

This longitudinal observational study included all patients receiving curative external beam radiotherapy for head and neck cancer aged 18 years or above from January 2018 to December 2018. Patient-related and treatment-related characteristics including age, gender, type, staging and site of cancer, history of smoking and diabetes, surface area exposed, and concurrent chemotherapy were compared in patients experiencing severe and non-severe acute skin and mucosal toxicity using the Radiation Therapy Oncology Group (RTOG) scoring system.

Results

Higher age (p = 0.002), TNM stage IV (p = 0.023), and concurrent administration of chemotherapy (p = 0.002) were statistically associated with severe acute radiation-induced skin and mucosa toxicity, whereas gender, surface area irradiated, history of smoking, and diabetes did not show such an association.

Conclusion

Older patients with TNM stage IV malignancy receiving concurrent chemotherapy are at a high risk of developing skin and mucosal toxicity that might interfere with the treatment protocol and warrant hospitalization, compromising their quality of life.

Comparative clinical characteristics among different age group of adult COVID-19 patients: A multicenter study

Background

Coronavirus disease (COVID‐19) is a global infectious disease with a large burden of illness and high health care costs. This study aimed to compare clinical features among adult COVID‐19 patients in different age groups.

Methods

Laboratory‐confirmed adult COVID‐19 infection cases between December 31, 2019 to March 8, 2020 obtained from Neighboring Cities. Patients were divided into five age groups. Clinical characteristics were compared among different age groups.

Results

Of 299 cases, median age was 44 and 158 (53%) were male. A total of 53.3% of 30–40 years, 50% of 40–50 years, 36.6% of <30 years and 36.2% of 50–60 years were primary case, none of the elderly were primary case. Among all the observed symptoms, only symptom of dyspnea was significantly different between the elderly group and other groups (p < .001). Proportion of severe or critical type was 2.4%, 5.3%, 9.5%, 14.5%, and 35% in patients with age <30, 30–40, 40–50, 50–65, ≥65, respectively. A total of 285 patients (95.3%) were cured and discharged, 12 patients (4.0%) were still on medical treatment in hospital. There were 2 (0.7%) deaths which occurred among persons ≥65 years. Patients with a history of chronic heart disease had a more than a 56 times higher risk for severe or critical type of COVID‐19 than those without a history of chronic heart disease (odds ratio [OR]: 56.038, 95% confidence interval [CI]: 2.764–1136.053, p = .009). Old age (OR: 1.055, 95% CI: 1.016–1.095, p = .006), high heart rate in admission (OR: 1.085, 95% CI: 1.03–1.144, p = .002), high respiratory rate in admission (OR: 1.635, 95% CI: 1.093–2.431, p = .017) were independently associated with severe or critical type in COVID‐19.

Conclusions

Proportion of severe or critical type increased with old age groups. Adults with old age and high heart rate, respiratory rate in admission and history of chronic heart disease were associated with severe or critical type in COVID‐19.

Establishing consensus for labeling and defining the later stage of anorexia nervosa: A Delphi study

OBJECTIVE

Varied perspectives on the later stage of anorexia nervosa (AN) have left the field of eating disorders without a consistent label or definition for this subpopulation. As a result, diverse criteria when recruiting participants have led to incomparable results across research studies and a lack of guidance when assessing and treating patients in the clinical context. The aim of the current study was to develop consensus-based guidelines on the labeling and defining of the later stage of AN.

METHOD

Utilizing the Delphi methodology, a professional panel of experts (N = 21) participated in three rounds of questionnaires. Five open-ended questions (Round 1) were analyzed using content analysis to form statements relating to a classification system for labeling and defining the later stage of AN. A total of 80 statements were rated in terms of panelists' level of agreement (Rounds 2 and 3).

RESULTS

Consensus was achieved for 28.8% of statements and a further 16.3% of statements reached near consensus in the second and third round of questionnaires. Two labels were identified with five defining features achieving consensus.

DISCUSSION

Findings from the study suggest an alternative approach to labeling be adopted with consensus-based guidelines established for defining the later stage of AN. Implications that may occur from a unified classification system are explored with longitudinal research required to assess the impact on patients experiencing the later stage of AN.

Real-life Cretan asthma registry focused on severe asthma: On behalf of 'The Cretan registry of the use of Biologics in Severe Asthma'

Asthma diagnosis and management remains a challenging task for the medical community. The aim of the present study was to present the functional and inflammatory profiles of patients with difficult-to-treat asthma in a real-life clinical setting referred to the specialized asthma clinic at the University Hospital of Heraklion. The registry included a cohort of 267 patients who were referred to the severe asthma clinic. Patients were assessed with emphasis on the history of allergies, nasal polyposis or other comorbidities. Blood testing for eosinophils counts and total and specific IgE, and pulmonary function tests were performed at baseline. The median age of patients with asthma was 55 years old, 68.5% were women and 58.3% were never smokers. The vast majority presented with late onset asthma (75.7%), whereas eight (3%) patients were on oral corticosteroids. The median number of exacerbations during the last 12 months was 1 (0-3). Furthermore, 50.7% of patients had a positive serum allergy test, the median eosinophil count was 300 (188-508.5) cells/µl of blood and median total IgE level was 117.5 (29.4-360.5) IU/ml. Patients were retrospectively grouped in the following categories: Group 1, mild-moderate asthma; group 2, patients prescribed a step 4 or 5 asthma therapy according to Global Initiative for Asthma; and group 3, patients on biologic agents. Group 1 had significantly higher FEV1% than groups 2 and 3 (93.4 vs. 79.9 and 79.4%, respectively; P<0.001). Finally, the median Asthma Control Questionnaire 7 (ACQ7) score was 1.14, with patients from groups 2 and 3 presenting higher ACQ7 scores compared with group 1 patients as expected (1.1 and 2.1 vs. 0.7, respectively; P<0.001). To the best of our knowledge, this was the first real-life asthma study in Crete that demonstrated that severe asthmatics predominantly have late-onset asthma with airflow obstruction and uncontrolled symptoms.

Monitoring Specific IgM and IgG Production Among Severe COVID-19 Patients Using Qualitative and Quantitative Immunodiagnostic Assays: A Retrospective Cohort Study

The purpose of this study is to monitor specific anti-severe acute respiratory syndrome coronavirus 2 (anti-SARS-CoV-2) IgG and IgM antibody production in patients with severe forms of coronavirus disease 2019 (COVID-19) using various commercially available quantitative and qualitative tests. The sera of 23 confirmed COVID-19 patients were processed for anti-SARS-CoV-2 IgG and IgM detection. Three different immunoassays, viz. Abbott Architect^® SARS-CoV-2 IgG assay, and two quantitative tests, ANSH^® SARS-CoV-2 and AESKULISA^® SARS-CoV-2 Nucleocapsid Protein (NP), were performed and the results pooled, from diagnosis to serum collection. Seroconversion rates were computed for all 3 assays, and possible correlations were tested using the Pearson correlation coefficient and Cohen’s kappa coefficient. Overall, 70 combinations of qualitative and quantitative IgG and IgM results were pooled and analyzed. In the early phase (0-4 days after diagnosis), in all tests, IgG seroconversion rates were 43%-61%, and increased in all tests gradually to 100% after 15 days. The Pearson correlation coefficient showed a strong positive relationship between the qualitative IgG test results and both quantitative IgG tests. IgM detection was inconsistent, with maximal concentrations and seroconversion rates between 10-15 days after diagnosis and slight-to-fair agreement between the two quantitative immunoassays. There was no significant association between mortality with IgG or IgM seroconversion or concentrations. Patients with severe COVID-19 develop an early, robust anti-SARS-CoV-2 specific humoral immune response involving IgG immunoglobulins. Further comparative studies are warranted to analyze the value of serological testing in predicting the severity of COVID-19 and detecting prior exposure.

Teaching academic skills to students with significant intellectual disabilities: A systematic review of the single-case design literature

Students with significant intellectual and developmental disabilities deserve access to instruction on academic skills in addition to functional skills. Many teachers, however, report challenges with identifying appropriate evidence-based practices to teach academics to these students. The purpose of this systematic review was to summarize and analyze literature on academic instruction for students with significant disabilities. Two hundred twenty-two articles with 225 experiments utilizing a single-case design and published between 1976 and 2018 were included in the review. Visual analysis indicated that, in most cases, interventions enabled students to make progress on targeted academic skills. The majority of studies focused on basic reading skills and included participants with moderate disabilities. Most studies used a combination of three or four evidence-based practices, with modeling, prompting, visual supports, time delay, and reinforcement being the most frequently used combination across studies.

Evaluation of Biomarkers of Severity in Patients with COVID-19 Infection

OBJECT

Although many Japanese patients infected with coronavirus disease 2019 (COVID-19) only experience mild symptoms, in some cases a patient's condition deteriorates, resulting in a poor outcome. This study examines the behavior of biomarkers in patients with mild to severe COVID-19.

METHODS

The disease severity of 152 COVID-19 patients was classified into mild, moderate I, moderate II, and severe, and the behavior of laboratory biomarkers was examined across these four disease stages.

RESULTS

The median age and male/female ratio increased with severity. The mortality rate was 12.5% in both moderate II and severe stages. Underlying diseases, which were not observed in 45% of mild stage patients, increased with severity. An ROC analysis showed that C-reactive protein (CRP), ferritin, procalcitonin (PCT), hemoglobin (Hb) A1c, albumin, and lactate dehydrogenase (LDH) levels were significantly useful for the differential diagnosis of mild/moderate I stage and moderate II/severe stage. In the severe stage, Hb levels, coagulation time, total protein, and albumin were significantly different on the day of worsening from those observed on the day of admission. The frequency of hemostatic biomarker abnormalities was high in the severe disease stage.

CONCLUSION

The evaluation of severity is valuable, as the mortality rate was high in the moderate II and severe stages. The levels of CRP, ferritin, PCT, albumin, and LDH were useful markers of severity, and hemostatic abnormalities were frequently observed in patients in the severe disease stage.

Organization, Clinical and Management Indicators on the First Year of Activity of an Outpatient Clinic Dedicated to the Diagnosis and Treatment of Severe Asthma in Italy

Purpose

A Regional Technical Commission was set in 2017 by Veneto region (Italy) to provide opinions and recommendations on drug prescriptions and to implement treatment-pathway guidelines for severe asthma. In this observational study, we describe the first structured, integrated, multidisciplinary, patient-centered outpatient clinic for the care of severe-asthma patients in Italy, and characterize patients referring to the center for specialist visits.

Patients and Methods

To characterize patients that accessed the outpatient clinic in 2018, data on demographic characteristics, treatments, severity of asthma, phenotypes, and relevant comorbidities by phenotype were collected. Use of biologic agents and indicators of the performance of the outpatient clinic were described.

Results

A structured multidisciplinary outpatient pathway for taking charge of patients and for administration and monitoring of biological agents was developed. A total of 146 patients accessed the outpatient clinic in 2018: 62.3% had uncontrolled asthma upon admission and 27.4% were already being treated with biologic agents. Among patients with uncontrolled asthma, 66% had severe uncontrolled asthma, 22% had moderate–severe uncontrolled asthma, and 12% had mild–moderate uncontrolled asthma. Main asthma phenotypes in uncontrolled-asthma patients were allergic (58% of patients), eosinophilic (22%), allergic plus eosinophilic (10%) and non-atopic asthma (10%). Among patients affected by severe asthma, 47% had allergic asthma, 28% had eosinophilic asthma, 13% had allergic plus eosinophilic asthma, and 12% had non-atopic asthma. Nasal polyps were more frequent in eosinophilic and allergic plus eosinophilic asthma, while gastro-esophageal reflux disease was more frequent in non-atopic asthma.

Conclusion

This structure of an outpatient clinic for the treatment of severe asthma, with its dedicated pathway and multidisciplinary approach, may allow a stricter control of asthma and optimization of therapies, as well as minimization of drug misuse.

The Neuropsychological Profile of Severe and Enduring Anorexia Nervosa: A Systematic Review

Characteristics of Severe and Enduring Anorexia Nervosa (SE-AN) are being investigated to differentiate the patients experiencing SE-AN from those at earlier stages of the AN disease. The current systematic review was the first step in exploring neuropsychological functioning as a potentially identifying characteristic for long-term presentations. With a subgroup of AN patients reflecting a unique neuropsychological profile that is proportionate to the quantity of patients that go on to develop SE-AN, it was the aim of this review to assess neuropsychological functioning in the later stage of the disease. In accordance with PRISMA guidelines, a literature search was conducted using four electronic databases (PsycINFO, MEDLINE, Web of Science, and Scopus) for neuropsychological research on AN participants with a seven or more year illness duration. Datasets that met inclusion criteria were screened for SE-AN participants (N = 166) and neuropsychological data extracted together with potentially confounding variables and information required to conduct a quality assessment. In research investigating decision-making, participants with a SE-AN presentation demonstrated significantly lower functioning compared to healthy controls. There was conflicting evidence for differences in intellectual functioning and set-shifting abilities with no variability indicated in central coherence, memory, attention, reasoning, or processing speed. If findings from this preliminary analysis are confirmed through empirical research, implications include earlier identification of SE-AN patients and more effective treatment development.

Etiology of Severe Acute Respiratory Infections, Bangladesh, 2017

In April 2017, surveillance detected a surge in severe acute respiratory infections (SARI) in Bangladesh. We collected specimens from SARI patients and asymptomatic controls for analysis with multipathogen diagnostic tests. Influenza A(H1N1)pdm09 was associated with the SARI epidemic, suggesting that introducing vaccines and empiric antiviral drugs could be beneficial.

The clinical effect of a bronchofiberscope in treating severe ventilator-associated pneumonia

OBJECTIVE

To analyze the clinical effect of fiberoptic bronchoscopy in treating severe ventilator-associated pneumonia (VAP).

METHODS

From September 2018 to October 2019, 100 patients with severe VAP were recruited as the study cohort and randomly divided into two groups, with 50 patients in each group. The control group underwent routine treatment, such as lavage, and the experimental group underwent fiberoptic bronchoscopy. The effectiveness rates, recovery times, and respiratory mechanics indexes of the two groups were compared.

RESULT

The total effective rate of the clinical treatment in the experimental group was significantly higher than it was in the control group (P < 0.05), and the recovery time in the experimental group was significantly shorter than it was in the control group (P < 0.05). After the treatment, the experimental group was significantly better than the control group (P < 0.05). After the treatment, the IL-8, CRP, and PCT levels in the experimental group were significantly lower than they were in the control group (P < 0.05).

CONCLUSION

Fiberoptic bronchoscopy can significantly improve the therapeutic effect of VAP, significantly shorten patients' recovery times, significantly improve the respiratory mechanics-related indicators, and improve the therapeutic effect, so it is worthy of promotion.
