Abstract
Hand-foot-mouth disease (HFMD) is a viral disease that occurs primarily in children. Meteorological factors have a significant impact on its popularity annually in Korea. This study proposes a new HFMD prediction model using a dual-attention-based recurrent neural network (DA-RNN) and important weather factors for HFMD in Korea. First, suspected cases of HFMD in each state were predicted using meteorological factors from the DA-RNN. Second, the weather factors were divided into six categories: temperature, wind, rainfall, day length, humidity, and air pollution to conduct sensitivity analysis. Because of this prediction, the proposed model showed the best performance in predicting the number of suspected HFMD cases in a week compared with other RNN methods. Sensitivity analysis showed that air pollution and rainfall play an important role in HFMD in Korea. This model provides information for HFMD prevention and control and can be extended to predict other infectious diseases.

Abstract
BACKGROUND School based-measures such as school closure and school holidays have been considered a viable intervention during the hand-foot-mouth disease (HFMD) epidemic. The aim of this study was to explore the association of nationwide public health and social measures (PHSMs) including planned school vacation on the transmissibility and attack rate of the HFMD epidemic in South Korea. METHODS In this study, we used Korean national surveillance data on HFMD from 2014 to 2019 to estimate the temporal changes in HFMD transmissibility (instantaneous reproductive number, Rt). Furthermore, to assess the changes in the HFMD attack rate, we used a stochastic transmission model to simulate the HFMD epidemic with no school vacation and nationwide PHSMs in 2015 South Korea. RESULTS We found that school vacations and 2015 PHSMs were associated with the reduced Rt by 2-7 % and 13 %, respectively. Model projections indicated school vacations and 2015 PHSMs were associated with reduced HFMD attack rate by an average of 1.10 % (range: 0.38-1.51 %). CONCLUSIONS PHSMs likely have a larger association with reduced HFMD transmissibility than school-based measures alone (i.e. school vacations). Preventive measures targeting preschoolers could be considered as potential options for reducing the future burden of HFMD.

ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2022; 29:50598-50607.

Abstract
Hand foot and mouth disease (HFMD) is a widespread public health concern but the studies on air pollution and the lengths of hospital stay (LOS) of HFMD are scarce nevertheless. Clinic demographic features among 5135 hospitalized HFMD cases in Nanjing, China, had been characterized from 2012 to 2017. Then, we had analyzed the association between PM2.5 short-term exposure as well as its components (OM, BC, SO42-, NH4+, NIT, SOIL, and SS) and the LOS of HFMD. Among these cases that were involved in our study, 98.62% were aged 0-6 years old, and 3772 (73.46%) were hospitalized within 1 week or less. The LOS of HFMD patients was different in various age ranges, illness onset years, and illness onset seasons (P < 0.01). For per IQR increase in PM2.5 concentrations, LOS of HFMD increased by 0.52 (0.33, 0.71), 0.50 (95% CI, 0.31-0.69) and 0.46 (95% CI, 0.28-0.65) day in adjusted models at lag 3 days, lag 7 days, and lag 14 days, respectively. In addition, per IQR increase of BC, SO42-, NH4+, NIT, and SOIL was also significantly associated with the LOS of HFMD. Our findings corroborated that short-term PM2.5 exposure was associated with the increased LOS of HFMD, and its components (BC, SO42-, NH4+, NIT, and SOIL) of PM2.5 might play a key role in prolonged LOS of HFMD.

Abstract
Hand, foot, and mouth disease (HFMD) caused by Enterovirus type 71 (EV71) is a serious threat to children's health. However, the pathogenic mechanism of EV71 is still unclear. Long non-coding RNAs (lncRNAs), some of which bind to miRNA as competitive endogenous RNAs (ceRNA) and weaken the silencing effect on the mRNA of downstream target genes, play a key role in regulating the viral infection process. In this study, through experimental verification, we found miR-4443 to be downregulated in cells infected with EV71. Next, by predicting lncRNAs that potentially regulate miR-4443, we found that EV71 infection induced upregulation of lncRNA ENST00000469812 and then further downregulated miR-4443 expression by direct interaction. We also demonstrated that nuclear protein 1 (NUPR1) is one of the target genes of miR-4443 and is involved in the ENST00000469812/miR-4443/NUPR1 regulatory axis. Finally, the ENST00000469812/miR-4443/NUPR1 regulatory axis exhibited a positive effect on EV71 replication. Here, we lay a foundation for exploring the pathogenic mechanism of EV71 and identify potential targets for HFMD treatment.

Application Effect of Medical Care Integration Combined with Family Intervention under the Evidence-Based Nursing Mode on Child Patients with Severe Hand-Foot-Mouth Disease and Its Influence on Intestinal Function. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2021; 2021:9599711. [PMID: 34671413 PMCID: PMC8523275 DOI: 10.1155/2021/9599711] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/02/2021] [Accepted: 09/29/2021] [Indexed: 12/02/2022]
Abstract
OBJECTIVE To explore the application effect of medical care integration combined with family intervention under the evidence-based nursing mode on child patients with severe hand-foot-mouth disease (HFMD) and its influence on intestinal function. METHODS 120 child patients with severe HFMD admitted to Qilu Children's Hospital of Shandong University from January 2019 to January 2020 were selected as the research object and randomly divided into group A and group B, with 60 cases each. Conventional nursing was performed on patients in group B, and medical care integration combined with family intervention under the evidence-based nursing mode was performed on patients in group A. Patients were assessed after the intervention using the hospital-made treatment adherence scale, PedsQLTM 4.0 (Pediatric Quality of Life Inventory Version 4.0) scale, and the faces pain scale-revised (FPS-R). The levels of gastrointestinal function indicators such as serum endotoxin (ET), diamine oxidase (DAO), and d-lactic acid (D-LA) were measured before and after the intervention, and recovery such as time to clear fever and time to relief of oral pain were recorded in both groups. RESULTS Children in group A had significantly higher compliance in diet, behaviour, exercise, and medication than group B (P < 0.05); the time to clear fever, time to relief of oral pain, time to healing of oral ulcers, time to relief of skin herpes, time to hospitalization, and time to eating were shorter in group A than those in group B (P < 0.001); all scores on the PedsQLTM 4.0 scale were higher in group A than those in group B after the intervention (P < 0.001); ET, DAO, and D-LA levels decreased in both groups after the intervention, with group A having lower levels than group B (P < 0.001), in addition, group A had lower eating pain scores after the intervention (P < 0.05). CONCLUSION Medical care integration combined with family intervention under the evidence-based nursing mode can effectively improve the treatment compliance of child patients with severe HFMD, accelerate their recovery progress, ensure a better prognostic quality of life and gastrointestinal tract function, and reduce the eating pain, indicating that such comprehensive nursing intervention mode should be promoted in practice.
