RESUMEN

BACKGROUND: Nonpharmaceutical interventions (NPIs) targeted at SARS-CoV-2 have remarkably affected the circulation of other respiratory pathogens, including respiratory syncytial virus (RSV). This study aimed to assess the changes in epidemiological and clinical characteristics of RSV infections in hospitalized children before and during the pandemic in Suzhou, China. METHODS: We prospectively enrolled children aged < 18 years who were hospitalized in Soochow University Affiliated Children's Hospital with acute lower respiratory infection (ALRIs) from January 2018 to July 2022. Changes in epidemiological and clinical characteristics of RSV infections were analyzed. RESULTS: Compared with the same period in 2018-2019, the difference in the overall positive rate of RSV was not statistically significant in 2020, while it increased significantly in 2021 (11.8% [662/5621] vs. 20.8% [356/1711], p < 0.001) and 2022 (9.0% [308/3406] vs. 18.9% [129/684], p < 0.001). Specifically, the positive rates declined considerably from October to December 2020 but sharply increased during the summer of 2021. Compared to prepandemic period, RSV infections were more frequently observed in older children during the pandemic. RSV-positive children exhibited milder clinical characteristics during the COVID-19 pandemic, including decreased proportion of patients with hospital stay ≥ 11 days (10.3% vs. 6.7%, p < 0.05), less requirement for oxygen therapy (13.7% vs. 6.9%, p < 0.001), and fewer cases of polypnea (12.2% vs. 9.7%, p < 0.05) and wheeze (50.1% vs. 42.9%, p < 0.001). CONCLUSIONS: The implementation of multilayered NPIs targeted at COVID-19 has affected the activity of RSV. Ongoing monitoring of RSV is warranted as the changing RSV epidemiology can provide valuable insights for future healthcare system planning.

RESUMEN

BACKGROUND: The approval of nirsevimab brings light to reducing the heavy disease burden caused by respiratory syncytial virus (RSV). Considering the seasonality of RSV, the timing of administrating monoclonal antibody (mAb) is critical to maximize health utility. This study aimed to model and seek the optimal seasonal mAb administration strategy for preventing RSV-associated hospitalization. METHODS: Age-season specific hospitalization rates for RSV-associated acute lower respiratory infection (RSV-ALRI) were estimated from a hospital-based birth cohort. Using these rates, we simulated and evaluated the effect of diverse mAb administration strategies on preventing RSV-ALRI hospitalization. Optimal strategies were selected based on their effectiveness and relative cost-effectiveness. RESULTS: Compared with the year-round strategy of administration mAb at birth for all children, 291 out of the 854 candidate strategies, featuring diverse administration timing and age thresholds, demonstrated a greater number of averted RSV-ALRI hospitalizations and a lower number needed to treat (NNT). The NNT represents the number of mAb doses needed to prevent one case of RSV-ALRI hospitalization. Among the 291 strategies, administration mAb to children born in July-January or August-January at birth and administrating to the remaining <12 months old children in September, exhibited the highest increase in averted RSV-ALRI hospitalizations than the year-round strategy, with a magnitude of 23 %, while also achieve an 18 % reduction in NNT. CONCLUSION: Administrating monoclonal antibodies to children born in July to January at birth, and administrating to the remaining <1-year-old children in September or October would be the optimal seasonal mAb administration strategy for children in Suzhou, China.

RESUMEN

BACKGROUND: The impact of pediatric body mass index (BMI) trajectories on the risk of adolescent hypertension (HTN) determined by three separate visits remains unclear. This longitudinal study aims to identify potential pediatric sex-specific BMI trajectories and to assess their associations with HTN and HTN subtypes. METHODS: Based on the Health Promotion Program for Children and Adolescents (HPPCA) in Suzhou, China, a total of 24,426 participants who had initial normal blood pressure (BP) and had at least four BMI measurements during 2012-2020 were included. HTN was defined as simultaneously having three separate visits of elevated BP in 2020. Latent class growth models were used to explore sex-specific BMI trajectories, whose associations with HTN and HTN subtypes were further examined by logistic regression. RESULTS: The incidence of HTN determined through three separate visits was 3.34%. Four trajectories were identified for both sexes: low BMI increasing, medium BMI increasing, high BMI increasing, and highest BMI increasing. Compared to the medium BMI increasing group, the odds ratio (95% confidential interval) for developing adolescent HTN of the low, high, and highest BMI increasing groups among boys were 0.54 (0.39, 0.75), 1.90 (1.44, 2.51), and 2.89 (1.90, 4.39), respectively; and the corresponding values for girls were 0.66 (0.48, 0.90), 2.30 (1.72, 3.09), and 4.71 (3.06, 7.26). Similar gradually elevated associations between different trajectories with isolated systolic hypertension, systolic and diastolic hypertension were observed. CONCLUSION: Current results emphasized the adverse effects of stable high BMI on HTN and the benefits of maintaining normal weight throughout childhood.

RESUMEN

INTRODUCTION: The COVID-19 pandemic‒related BMI gain and obesity prevalence changes in children have not been clearly elucidated, especially in China. This study aims to assess the impact of pandemic-related BMI and obesity prevalence change in Chinese children aged 8-12 years. METHODS: On the basis of the Health Promotion Program for Children and Adolescents in Suzhou of China, a total of 72,175 children aged 8-12 years with complete data during 2017-2020 were included. Yearly BMI z-score changes and age- and sex-adjusted BMI changes before (2017-2019) and during (2019-2020) the pandemic were calculated. Multivariate mixed linear models were used to examine the possible difference in annual BMI change rate before and during the pandemic among subgroups. RESULTS: The obesity prevalence slightly increased from 12.29% (2017) to 13.28% (2019) but substantially increased to 15.29% in 2020. The mean yearly change in BMI z-score before and during the pandemic were 0.039 (95% CI=0.037, 0.042) and 0.131 (95% CI=0.125, 0.138), respectively, yielding a difference of 0.092 (95% CI=0.087, 0.096). Similarly, changes and age- and sex-adjusted BMI increased by 0.191 (95% CI=0.179, 0.202) during the pandemic compared with those of previous years. Meanwhile, the increase in BMI changes in 2019-2020 compared with that before the pandemic was more obvious in boys than in girls and in underweight or normal-weight children than in their overweight and obese counterparts. CONCLUSIONS: BMI gain increased among Chinese children aged 8-12 years during the pandemic. There is an urgent need to formulate effective public health policies to reduce the risk of pandemic-related childhood obesity.

RESUMEN

INTRODUCTION: This study aimed to explore the association between the IRAK4 polymorphism rs4251545 and the severity of enterovirus 71 (EV71) infection in Chinese children. METHODS: We analyzed the IRAK4 polymorphism rs4251545 in 617 EV71-infected patients and 410 controls using the improved multiplex ligation detection reaction. IRAK4 mRNA expression was tested by qRT-PCR. Serum concentrations of IL-6 and NF-κB were detected using ELISA. RESULTS: The frequencies of the GA + AA genotype and A allele in the mild EV71 infection group and in the severe EV71 infection group were significantly higher than those in the normal control group. The frequency of the GA + AA genotype and A allele in severely infected EV71 patients was markedly higher than that in mildly infected EV71 patients. IRAK4 mRNA expression in mildly infected EV71 patients and severely infected patients was significantly higher than that in the control group. IRAK4 mRNA expression in GA + AA genotypes in both mild and severe EV71 infection groups was significantly higher than that in patients with the GG genotype. IL-6 concentration and the ratio of IL-6/NF-κB in severe EV71 cases were significantly lower in patients with the GA + AA genotype than in those with the GG genotype. The ratio of IL-6/NF-κB was distinctly higher in severely infected EV71 patients than in mildly infected and control subjects. CONCLUSIONS: The IRAK4 polymorphism rs4251545 was associated with the susceptibility and severity of EV71 infection. The A allele is a susceptible factor in the development of severe EV71 infection in Chinese children.

RESUMEN

The mutations in modifier genes may contribute to some inherited diseases including Wilson disease (WD). This study was designed to identify potential modifier genes that contribute to WD. A total of 10 WD patients with single or no heterozygous ATP7B mutations were recruited for whole-exome sequencing (WES). Five hundred and thirteen candidate genes, of which the genetic variants present in at least two patients, were identified. In order to clarify which proteins might be involved in copper transfer or metabolism processes, the isobaric tags for relative and absolute quantitation (iTRAQ) was performed to identify the differentially expressed proteins between normal and CuSO4-treated cell lines. Thirteen genes/proteins were identified by both WES and iTRAQ, indicating that disease-causing variants of these genes may actually contribute to the aberrant copper ion accumulation. Additionally, the c.86C > T (p.S29L) mutation in the SLC31A2 gene (coding CTR2) has a relative higher frequency in our cohort of WD patients (6/191) than reported (0.0024 in gnomAD database) in our healthy donors (0/109), and CTR2S29L leads to increased intracellular Cu concentration and Cu-induced apoptosis in cultured cell lines. In conclusion, the WES and iTRAQ approaches successfully identified several disease-causing variants in potential modifier genes that may be involved in the WD phenotype.

RESUMEN

BACKGROUND: A body shape index (ABSI) is an emerging anthropometric indicator, challenging two traditional parameters: body mass index (BMI) and waist circumference (WC). We aimed to systematically compare and validate the capability of anthropometric indicators for determining pediatric high blood pressure (HBP). METHODS: A total of 3150 participants aged 7-17 years were enrolled from Suzhou, China. Areas under the receiver operating characteristic curve (AUC) were obtained to evaluate the performance of anthropometric indicators in detecting HBP. DeLong's test was used to examine whether the AUCs of anthropometric indicators in contrast to BMI or original ABSI were statistically different. Furthermore, a meta-analysis was performed to combine results from this study and five similar articles from databases. RESULTS: In Suzhou population, BMI exhibited the largest AUC (AUC = 0.705), followed by WC (AUC = 0.669) and original ABSI (AUC = 0.514). Modified ABSI (AUC: 0.537-0.681), although had slightly better performance than original ABSI, was still less valuable than BMI (P < 0.05), either in the total sample or in boys. The meta-analysis with 21108 children and adolescents subsequently confirms the results derived from Suzhou population. CONCLUSIONS: In predicting pediatric HBP, original ABSI and modified ABSI underperform BMI and WC. IMPACT: The current study is the first to evaluate whether original ABSI or modified ABSI is comparable to BMI and WC for screening HBP in children and adolescents. In predicting pediatric HBP, original ABSI and modified ABSI do not perform as well as traditional anthropometric indicators, such as BMI and WC. BMI remains the optimal indicator in pediatric HBP screening. This study provides a theoretical basis for the early identification of HBP in children and adolescents by adopting effective predictors.

RESUMEN

OBJECTIVE: To investigate the effect of the FOCUS-PDCA procedure on the self-care ability of patients undergoing colostomy for rectal cancer. METHOD: A nonrandomized controlled trial of 160 patients with rectal cancer undergoing colostomy. The control group received routine nursing intervention, and the observation group received the FOCUS-PDCA procedure. The self-care ability of the two groups was investigated 1 week and 1 month after surgery, and a comparative analysis was made between the groups. RESULTS: One week after surgery, the self-care ability of rectal cancer patients with colostomy increased from 39.09 points before implementation of the FOCUS-PDCA procedure to 60.15 points after implementation; an increase of 21.06%. One month after surgery, the self-care ability increased from 61.50 points to 83.13 points after implementation of the FOCUS-PDCA procedure; an increase of 21.63%. CONCLUSION: Application of the FOCUS-PDCA procedure improved the self-care ability of rectal cancer patients undergoing colostomy, improved their physical and mental health, reduced colostomy complications, and improved their quality of life. The results suggest that it is worth applying FOCUS-PDCA more widely.

RESUMEN

Polycystic kidney disease with Tuberous sclerosis is a disease caused by the deletions of the TSC2-PKD1 gene. The disease is rarely reported and the characterized manifestation is severe polycystic kidney growth. The diagnosis can be made by molecular analysis. We report the first case of PKDTS discovered in infancy in China with typical neurological and renal manifestations. The patient has infantile spasm, polycystic kidney, skin damage, hypertension, and hematuria after infection. After effective treatment of Rapamycin, the seizures were completely controlled. There was not been any renal function damage in the patient. At the same time, we review the related literature and further elaborate on the variety of clinical manifestations, treatment, and prognosis.

RESUMEN

Metachromatic leukodystrophy(MLD) is an autosomal recessive hereditary neurodegenerative lysosomal storage disorder caused by the mutations in arylsulfatase A gene (ARSA), which results in the deficiency of ARSA enzyme. The common clinical characteristics of MLD are abnormal gait, and then gradually appears ataxia, spastic quadriplegia, optic atrophy, cortical blindness, and dementia. We describe two patients in China who were diagnosed with MLD and find that the four ARSA gene mutations (c.1115G>A, c.302G>T, c.893 G> T, and c.302G>T) are associated with MLD, in which c.893 G>T and c.302G>T are novel mutations by gene sequence and clinical manifestations, to further understand the relationship between MLD and ARSA gene.

RESUMEN

STUDY OBJECTIVE: To compare the efficacy and safety of once-weekly and twice-weekly bortezomib therapy in patients with hematologic malignancies. DESIGN: Meta-analysis of 13 clinical or randomized controlled trials, with trial sequential analysis (TSA). PATIENTS: A total of 1567 patients with hematologic malignancies who received either once-weekly or twice-weekly bortezomib therapy. MEASUREMENTS AND MAIN RESULTS: We conducted a comprehensive literature search of the PubMed, EMBASE, and Cochrane Library databases. A meta-analysis was conducted to calculate the pooled effect size; TSA was performed to assess the reliability of the pooled results. The pooled risk ratio (RR) for the overall response rate (ORR) was 1.00 (95% confidence interval [CI] 0.77-1.29, p=0.99), indicating no significant differences between patients who received once-weekly bortezomib and those who received twice-weekly bortezomib. TSA showed that the cumulative Z-curve of the ORR entered the futility area, implying that reliable evidence was obtained for this pooled result. The pooled RR for any grade of peripheral neuropathy was 0.48 (95% CI 0.26-0.88, p=0.02); however, the TSA plot revealed that there was insufficient evidence for this result. The pooled RR for peripheral neuropathy grade 3 or higher was 0.21 (95% CI 0.13-0.34, p<0.00001), and reliable evidence was obtained according to TSA. Regarding the other toxicities, including anemia, thrombocytopenia, neutropenia, infection, diarrhea, constipation, nausea, vomiting, and fatigue, we did not find any significant differences between patients who received once-weekly bortezomib and those who received twice-weekly bortezomib. CONCLUSION: Compared with twice-weekly bortezomib, once-weekly bortezomib had a comparable ORR and a probable lower incidence of peripheral neuropathy. More clinical trials are needed to draw a conclusion regarding the difference in peripheral neuropathy between the two groups because of the insufficient evidence detected by TSA and the inconsistent results among subgroups.

RESUMEN

BACKGROUND: Climate change may lead to emerging and re-emerging infectious diseases and pose public health challenges to human health and the already overloaded healthcare system. It is therefore important to review current knowledge and identify further directions in China, the largest developing country in the world. METHODS: A comprehensive literature review was conducted to examine the relationship between climate variability and infectious disease transmission in China in the new millennium. Literature was identified using the following MeSH terms and keywords: climatic variables [temperature, precipitation, rainfall, humidity, etc.] and infectious disease [viral, bacterial and parasitic diseases]. RESULTS: Fifty-eight articles published from January 1, 2000 to May 30, 2018 were included in the final analysis, including bacterial diarrhea, dengue, malaria, Japanese encephalitis, HFRS, HFMD, Schistosomiasis. Each 1 °C rise may lead to 3.6%-14.8% increase in the incidence of bacillary dysentery disease in south China. A 1 °C rise was corresponded to an increase of 1.8%-5.9% in the weekly notified HFMD cases in west China. Each 1 °C rise of temperature, 1% rise in relative humidity and one hour rise in sunshine led to an increase of 0.90%, 3.99% and 0.68% in the monthly malaria cases, respectively. Climate change with the increased temperature and irregular patterns of rainfall may affect the pathogen reproduction rate, their spread and geographical distribution, change human behavior and influence the ecology of vectors, and increase the rate of disease transmission in different regions of China. CONCLUSION: Exploring relevant adaptation strategies and the health burden of climate change will assist public health authorities to develop an early warning system and protect China's population health, especially in the new 1.5 °C scenario of the newly released IPCC special report.

RESUMEN

PURPOSE: We performed this meta-analysis to compare the efficacy and safety between two different administration routes of bortezomib, subcutaneous and intravenous. METHODS: Six retrospective studies and three randomized controlled trials (RCTs) were included in our study. Data from retrospective studies or RCTs were pooled and displayed in their corresponding subgroup, retrospective studies subgroup or RCTs subgroup. We comprehensively compared the overall response rate (ORR) and the incidence of adverse events between subcutaneous and intravenous bortezomib. RESULTS: We did not find statistical difference in ORR between the two administration routes. The pooled RRs for ORR were 0.99 (95% CI = 0.79 - 1.25, p = 0.95; retrospective studies subgroup) and 1.02 (95% CI = 0.93 - 1.11, p = 0.69; RCTs subgroup). Compared with intravenous bortezomib, the subcutaneous bortezomib reduced the incidence of peripheral neuropathy, both any grade and grade ≥ 3. The pooled RRs for any grade of peripheral neuropathy were 0.33 (95% CI = 0.15 - 0.71, p = 0.004; retrospective studies subgroup) and 0.55 (95% CI = 0.31 - 0.97, p = 0.04; RCTs subgroup), and for peripheral neuropathy grade ≥ 3 were 0.40 (95% CI = 0.16 - 0.95, p = 0.04; retrospective trials subgroup) and 0.39 (95% CI = 0.19 - 0.80, p = 0.01; RCTs subgroup). Only retrospective trials subgroup found that the incidence of thrombocytopenia and renal and urinary disorders were lower in subcutaneous bortezomib than in intravenous, with the pooled RRs 0.46 (95% CI = 0.29 - 0.72, p = 0.0007; retrospective trials subgroup) and 0.23 (95% CI = 0.09 - 0.56, p = 0.001; retrospective trials subgroup), respectively. The RCTs subgroup did not find statistical differences in these two adverse events. CONCLUSIONS: Subcutaneous bortezomib did not significantly reduce therapeutic efficacy but resulted in a lower incidence of peripheral neuropathy than intravenous bortezomib. Compared with intravenous bortezomib, subcutaneous bortezomib might reduce the incidence of thrombocytopenia and renal and urinary disorders, but this needs more clinical trials to confirm.

RESUMEN

OBJECTIVE: To explore the effect of renal replacement therapy (RRT) on the plasma drug concentration of first-line antituberculosis drugs. METHODS: Thirty patients treated with continuous RRT and who were complicated with pulmonary tuberculosis from 2009 September to 2013 September were enrolled in the study. There were 19 males and 11 females, aged 18-75 years. They received RRT 3 times a week, 4 h each. The patients took isoniazid 300 mg and rifampin 450 mg one time every day, and pyrazinamide 40 mg · kg(-1) · d (-1) one time 24 h before RRT, 3 times every week. The plasma concentration of the drugs were monitored before and after each RRT for 4 weeks. RESULTS: Taken before RRT, the plasma concentration of isoniazid before RRP was (1.62 ± 0.44), (1.67 ± 0.38), (1.63 ± 0.41), (1.48 ± 0.38) mg/L respectively for 1-4 weeks; while that after RRT was (0.57 ± 0.22), (0.60 ± 0.24), (0.56 ± 0.20), (0.56 ± 0.15) mg/L (all P < 0.05). Taken before RRT, the plasma concentration of pyrazinamide before RRT was (16.08 ± 4.95), (16.32 ± 5.73), (14.89 ± 4.53), (13.81 ± 5.83) mg/L respectively for 1-4 weeks, while that after RRT was (3.73 ± 1.57), (3.57 ± 1.53), (3.22 ± 1.00), (2.81 ± 1.34) mg/L (all P < 0.05). Taken after RRT at once, the plasma concentration of pyrazinamide before RRT was (15.57 ± 3.47), (14.10 ± 2.27), (14.73 ± 2.36), (15.9 ± 3.02) mg/L respectively for 1-4 weeks, while that after RRT was (2.45 ± 1.14), (2.19 ± 1.07), (1.87 ± 1.52), (2.33 ± 1.30)mg/L. Taken before RRT, the plasma concentration of rifampin was (3.44 ± 1.17), (3.72 ± 1.24), (3.68 ± 1.16), (3.44 ± 1.22) mg/L respectively for 1-4 weeks (all P < 0.05), while that after RRT was (2.96 ± 1.10), (3.28 ± 1.04), (3.17 ± 1.02), (2.96 ± 1.05) mg/L (all P > 0.05). CONCLUSIONS: Continuous RRT has different effects on the plasma drug concentration of isoniazid and pyrazinamide. It almost has no effect on rifampin. To achieve the best plasma concentration and better anti-tuberculosis results, isoniazid and pyrazinamide should be taken after RRT, but rifampin before RRT.

RESUMEN

BACKGROUND: Currently, hepatitis B immunoglobulins (HBIg) and/or lamivudine have become the main options for prevention of hepatitis B recurrence after liver transplantation. AIM: To assess the benefits of HBIg and/or lamivudine for prevention of hepatitis B recurrence after liver transplantation. METHODS: We conducted a search of electronic databases and a manual search of bibliographical lists of relevant articles. All randomized clinical trials and non-randomized studies that meet the pre-specified criteria were included. However, results of non-randomized studies were reported under 'exploratory analyses' in the result section. The outcome measure was hepatitis B recurrence. RESULTS: Two randomized and 44 non-randomized studies were included. Meta-analysis of two randomized studies shows one week HBIg combined with lamivudine regimen had equivalent effect compared with long-term high-dose HBIg regimen for preventing hepatitis B recurrence (RR 1.23; 95% CI 0.38-4.03; P = 0.73). For 44 non-randomized studies, only qualitative systematic review was performed. With long-term HBIg prophylaxis, hepatitis B recurrence rate ranged from 3.7% to 65%; with lamivudine prophylaxis, hepatitis B recurrence rate varied from 3.8% to 40.4%; Long-term high-dose HBIg plus lamivudine prophylaxis can reduce the risk of HBV recurrence to less than 10%. CONCLUSIONS: Long-term HBIg prophylaxis or lamivudine prophylaxis can reduce the risk for hepatitis B virus recurrence. Long-term high-dose HBIg combined with lamivudine can further reduce HBV recurrence to less than 10%.
