Etiological characteristics of viral gastroenteritis in pediatric inpatients under five years old in Shanghai， 2021‒2022 / 上海预防医学

ObjectiveTo investigate the changes in the pathogen spectrum of viral diarrhea in local pediatric inpatients as well as any variations in genotypes of major pathogens during the COVID-19 control period. MethodsFecal samples were collected from the children <5 years who were hospitalized due to acute gastroenteritis in a pediatric hospital in Shanghai. PCR test was carried out to detect rotavirus， norovirus， sapovirus， astrovirus and enteric adenovirus， and then genotyping was performed for major pathogens. ResultsOut of 546 samples， 37.55% tested positive for virus with the following positive rate ranking： norovirus GⅡ （22.16%）， group A rotavirus （16.12%）， astrovirus （2.93%）， enteric adenovirus （2.38%）， sapovirus （0.92%） and norovirus GⅠ （0.18%）. The predominant genotype within norovirus GⅡ were GⅡ.4［P31］ and GⅡ.4［P16］ with a proportion of 24.79% and 14.05% respectively. The detection rate of GⅡ.4［P31］ dropped significantly over the 2-year period （χ2＝16.140，P<0.001）. In addition， an emerging rotavirus genotype G8P ［8］， which was rarely found nationally， was discovered for the first time locally with an increasing proportion， accounting for 7.95% of all rotavirus positive cases. Phylogenic analysis demonstrated that the representative strains of this genotype were genetically closer to the DS-1-like G8P ［8］ strain found in Southeast Asia. ConclusionThe changes in the prevalence of various norovirus genotypes together with the emergence of rare rotavirus genotype in the local area illustrate the importance of continuous monitoring of viral diarrhea and genotyping of key pathogens. Increased local activity of the rare genotype also adds new parameters in the efficacy evaluation of marketed vaccines and development of potential new vaccines in near future.

Peripheral blood parameters for predicting PICU admission and mechanical ventilation in pediatric inpatients with human parainfluenza virus-induced pneumonia.

Human parainfluenza viruses (hPIVs)-induced pneumonia is an important cause of pediatric hospitalization, and some develop severe pneumonias requiring pediatric intensive care unit (PICU) admission and mechanical ventilation (MV). The aim of this study is to investigate the value of peripheral blood (PB) parameters available on admission in predicting the need for PICU admission and MV due to pneumonia caused by hPIVs. A total of 331 cases including 277 (83.69%) on the general ward (GW) and 54 (16.31%) on the PICU were enrolled between January 2016 and June 2021. Of 54 patients admitted to the PICU, 24 patients (7.25%) received MV, whereas 30 (9.06%) did not. For both the PICU and GW groups, infants accounted for the highest proportion while school children had the lowest. Compared with the GW group, the PICU group had significantly higher rates of premature birth, fatigue, sore throat, headache, chest pain, tachypnea, dyspnea, and underlying diseases including congenital tracheal stenosis, congenital heart disease (CHD), metabolic disorder, and neurological disorder (ND), but significant lower proportion of exclusive breastfeeding and Z-scores for weight-for-height, weight-for-age, height-for-age, and body-mass-index (BMI)-for-age (BMIZ). Higher levels of some leukocyte differential counts (LDC)-related parameters including counts of neutrophil (N), ratios of neutrophil-to-lymphocyte ratio (NLR), derived neutrophils/(leukocytes minus neutrophils) ratio (dNLR), and platelet-to-lymphocyte ratio (PLR), lower levels of some other LDC-related parameters including lymphocyte (L) and monocyte (M) counts, ratios of lymphocyte-to-monocyte ratio (LMR), lymphocyte-to-C-reactive protein ratio, and prognostic nutritional index (PNI), and lower levels of PB protein (PBP)-related parameters including red blood cell (RBC), hemoglobin, total protein (TP), and serum albumin were observed in the PB of patients in the PICU compared with those in the GW. Notably, higher PLR level and two comorbidities including CHD and ND were identified as independent risk factors for PICU admission, while lower PNI level as well as smaller numbers of RBC and L as good predictors. Low levels of TP might be a useful predictor of the need for MV. Overall, the relative contributions of LDC- and PBP-related factors for accurate identification of patients required PICU admission accounted for 53.69% and 46.31%, respectively. Thus, determination of whether a patient with hPIVs-induced pneumonia is admitted to PICU involves consideration of both the LDC- and PBP-related parameters.

Prevalence and Correlates of Sleep Disorders Among Pediatric Inpatients in a Tertiary Pediatric Hospital.

Background It is possible to define sleep disorders as any disturbance in sleep timing, quality, or quantity that results in daytime distress and impairment in functioning that, in turn, affects the baseline functional status of an individual. Our study aimed to describe how sleep disorders might affect pediatric inpatients at King Abdulaziz University Hospital (KAUH) as well as estimate their prevalence (2021-2022). We assessed the sleep habits using questionnaires and analyzed and combined these data to create rankings to compare the different issues affecting sleep habits in pediatric patients. Methodology Two scoring systems were used in this study, namely (a) the Children's Sleep Habits Questionnaire (CSHQ) and (b) the Pediatric Sleep Questionnaire. Analyses of the data were conducted using SPSS version 23 (IBM Corp., Armonk, NY, USA) and GraphPad Prism version 8 (GraphPad Software, Inc., San Diego, CA, USA). Results The prevalence of sleep disorders and their correlations were evaluated among 98 pediatric inpatients at KAUH, Saudi Arabia, between 2021 and 2022. The average duration of hospital stay was 11.97 ± 11.0 days (N = 78), and the average number of previous admissions was 2.85 ± 3.7 (N = 93). Conclusions According to the sleep behavior domain of the CSHQ, most children woke up sweating, screaming, and inconsolable during the night. Furthermore, bedtime resistance and sleep anxiety were the most prevalent sleep disturbances observed in the study population.

Impact of a same day admission project in reducing the preoperative bed occupancy demand in a pediatric inpatient hospital.

Background: A same day admission approach was established for pediatric patients undergoing elective surgery owing to an increase in demand for bed availability and the need for medical, logistical, psychological, and fiscal improvements. This study aimed to assess the effectiveness of the same day admission approach for reducing demand for preoperative bed occupancy in pediatric inpatient units. Method: Data on elective surgery patients considered for same day admission were prospectively collected in an Excel spreadsheet. Results: Same day admission patients numbered 269 (25.87%; n = 1040), 461 (41.7%; n = 1104), 382 (38.67%; n = 998), and 560 (44.20%; n = 1267) in 2018, 2019, 2020, and 2021, respectively. Over the 4-year period between 2018 and 2021, pediatric orthopedic surgeries accounted for the majority of same day admissions (29.72%; n = 497), followed by ear, nose, and throat (21.30%; n = 356), general (16.99%; n = 284), plastic (14.53%; n = 243); urology (9.87%; n = 165); optometry and ophthalmology (3.77%; n = 63); neuro (2.51%; n = 42), and dental (1.31%; n = 22) surgeries. The total number of days of saved preoperative beds over the 4-year period was 1672 days (an average of 418 hospital days per year). Conclusions: This study showed that same day admission approach should be implemented in pediatrics institutions to reduce hospital bed demand. The implementation of this initiative is widely variable between specialties due to interlinked medical, operational, and logistical factors. Level of Evidence: III.

The A2c111nt-dup variants of human metapneumovirus predominantly circulating in Qingdao, China, during 2018 and 2019.

Human metapneumovirus (HMPV) plays an important role in acute respiratory tract infections (ARTIs), especially in children. We investigated the epidemiology of HMPV associated with ARTIs among pediatric inpatients and identified HMPV genetic variations in Qingdao, China, from January 2018 to June 2019. HMPV-positive samples were identified from throat swabs by multiplex real-time reverse transcriptase polymerase chain reaction (RT-PCR). The G gene sequences of HMPV were obtained, followed by phylogenetic analysis. As a result, 71 out of 1051 (6.76%) patients were HMPV positive, and the HMPV-positive rate in children under 5 years of age was three times higher than that in those aged 5-17 years. The epidemic season of HMPV was in spring, with a peak mainly in March. Thirty-two nucleotide sequences of the HMPV G gene successfully obtained were clustered into three genotypes, A2c (25/32, 78.13%), B1 (3/32, 9.38%) and B2 (4/32, 12.50%). In addition, 76% (19/25) of A2c viruses were identified as the emerging A2c111nt-dup variants, which were predominantly circulating among pediatric inpatients with ARTIs between January 2018 and June 2019 in Qingdao. The emerging A2c111nt-dup variants have spread between countries and cities and might spread more widely in the future. Further prevalence monitoring of this duplication variant is needed to clarify the potentially expanding transmission and to provide a scientific basis for disease control and vaccine development.

Respiratory viruses among pediatric inpatients with acute lower respiratory tract infections in Jinan, China, 2016-2019.

The viral etiologies responsible for acute lower respiratory tract infections (ALRI) are a major cause of pediatric hospitalization, and some develop severe diseases requiring pediatric intensive care unit (PICU) admission. The aim of this study is to determine the prevalence of viruses and risk factors associated with PICU admission among patients hospitalized for ALRI. Nasopharyngeal swabs were collected to detect human rhinovirus (HRV), influenza A and B viruses (IAV and IBV), parainfluenza viruses (PIV), and respiratory syncytial virus (RSV) by reverse transcription-polymerase chain reaction (PCR) and adenovirus (ADV) by PCR. Of the 5590 pediatric inpatients enrolled, respiratory viral infection occurred in 2102 (37.60%) patients, including 1846 (33.02%) single and 256 (4.58%) mixed viral infections. Among the nasopharyngeal swabs from pediatric inpatients, HRV accounted for the highest detection rate (16.48%), followed by PIV (8.35%), RSV (7.41%), ADV (4.63%), IAV (3.51%), and IBV (2.08%). The positive rate of viral tests decreased with increasing age and was higher in males (39.29%) than females (34.67%). The prevalence of viral infection was the highest in winter (41.57%) and lowest in autumn (31.78%). Each virus had a seasonal pattern, with peaks occurring in months of their epidemic seasons. RSV infection and the presence of comorbidities including congenital tracheal stenosis, congenital heart disease, metabolic disorder, immunodeficiency, renal disease, gastrointestinal disease, and neurological disorder might be associated with the need for PICU admission. Therefore, this study provides useful information for the prevention and control of virus-related respiratory diseases and the early identification of and intervention in severe cases.

Predictors of parent's knowledge of hospital-based pediatric falls.

PURPOSE: This study aimed to validate and to determine the individual characteristics and demographic factors associated with parents' knowledge of hospital-based pediatric falls and to identify parent populations more likely to report low levels of falls-related knowledge. DESIGN: Validation of a questionnaire and a cross-sectional survey design. METHODS: Parents (n = 200) of hospitalized children admitted to a tertiary specialist pediatric hospital in Australia completed an online questionnaire. Parents were asked to rate their hospital-based falls knowledge using a Likert scale (1-5). The questionnaire was administered to parents across six hospital wards, 1 day a week, from May to August 2019. Validation of the questionnaire involved factor analyses and reliability tests. Finally, descriptive analysis measured parents' knowledge, and a multivariate logistic regression analysis reported factors associated with parents' falls knowledge. All data were analyzed in Statistical Package for the Social Sciences (V27). Ethical approval was received for all stages. RESULTS: The final version of the parent knowledge of falls (PKOF) questionnaire consisted of 23 questions across five domains (Cronbach α = .929-.70). Parents' knowledge of hospital-based falls ranged from 2.5 to 4.5, while knowledge that children may fall during parental presence rated the lowest score. Knowledge of inpatient falls was higher if their child had a high risk of falls (odds ratio [OR]: 2.1, p = .04) and they were Australian-born parents (OR: 1.9, p = .05). PRACTICE IMPLICATIONS: The PKOF questionnaire is an evidence-based instrument developed for a pediatric hospital setting. Findings highlight knowledge gaps and parent groups with the highest risk of having inadequate hospital-based falls knowledge. The questionnaire enables pediatric nurses and educators to measure parents' knowledge of hospital-based falls accurately and consistently, and so to identify gaps and, subsequently, develop, implement, and evaluate falls education using an evidence-based approach.

SARS-CoV-2 in Pediatric Inpatient Care: Management, Clinical Presentation and Utilization of Healthcare Capacity.

This study scrutinizes management and clinical presentation of severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) in pediatric inpatient care and evaluates the utilization of pediatric healthcare capacity during the pandemic. Within this retrospective cohort study, we systematically reviewed data of all 16,785 pediatric patients (<18 years admitted to our clinical center between January 2018 and June 2021). Data on SARS-CoV-2 test numbers, hospital admissions and clinical characteristics of infected patients were collected. Since January 2020, a total of 2513 SARS-CoV-2 tests were performed. In total, 36 patients had a positive test result. In total, 25 out of 36 SARS-CoV-2 positive children showed at least mild clinical symptoms while 11 were asymptomatic. Most common clinical symptoms were fever (60%), cough (60%) and rhinitis (20%). In parallel with the rising slope of SARS-CoV-2 in spring and fall 2020, we observed a slight decrease in the number of patients admitted to the pediatric department while the median duration of hospital treatment and intensive care occupancy remained unchanged. This study underlines that SARS-CoV-2 infected children most frequently exhibit an asymptomatic or mild clinical course. Noteworthy, the number of hospital admissions went down during the pandemic. The health and economic consequences need to be discussed within health care society and politics.

Adverse Drug Events due to Central Nervous System Depressant Drugs in Pediatric Patients With or Without Surgery.

OBJECTIVES: To identify differences in the incidence and severity of adverse drug events (ADEs) due to CNS depressant drugs among pediatric patients with and without surgery. METHODS: The Japan Adverse Drug Events Study was a cohort study enrolling pediatric inpatients. Potential ADEs were identified by onsite review of medical charts, incident reports, and prescription queries. Two independent physicians classified ADEs and severity. We compared the incidence and characteristics of ADEs between pediatric patients with surgery (surgery group) and without surgery (non-surgery group). We evaluated severity of ADEs due to CNS depressant drugs among both groups. RESULTS: We enrolled 944 patients, 234 in surgery group and 710 in non-surgery group. A total of 480 ADEs due to any drugs occurred in 225 patients. Among 81 ADEs due to CNS depressant drugs, 42 ADEs were in surgery group, whereas 39 were in non-surgery group. The risk of fatal or life-threatening ADEs due to CNS depressant drugs was significantly higher than other drugs (12% vs. 2%, p < 0.001). In the surgery group, anesthetics led to 2 fatal or life-threatening, 8 serious, and 30 significant ADEs, whereas in the non-surgery group anesthetics led to 2 fatal or life-threatening, 5 serious, and 4 significant ADEs. Anesthetics were higher risk in the non-surgery group (p = 0.049). CONCLUSIONS: The risks of fatal and life-threatening ADEs were significantly higher with CNS depressant drugs than other drugs. Pediatric patients without surgery have higher risks of fatal or life-threatening ADEs due to anesthetics than those with surgery.
