INTRODUCTION: Obstructive sleep apnoea (OSA) is common in Singapore, with moderate to severe OSA affecting around 30% of residents. These consensus statements aim to provide scientifically grounded recommendations for the management of OSA, standar-dise the management of OSA in Singapore and promote multidisciplinary collaboration. METHOD: An expert panel, which was convened in 2024, identified several areas of OSA management that require guidance. The expert panel reviewed the current literature and developed consensus statements, which were later independently voted on using a 3-point Likert scale (agree, neutral or disagree). Consensus (total ratings of agree and neutral) was set a priori at ≥80% agreement. Any statement not reaching consensus was excluded. RESULTS: The final consensus included 49 statements that provide guidance on the screening, diagnosis and management of adults with OSA. Additionally, 23 statements on the screening, diagnosis and management of paediatric OSA achieved consensus. These 72 consensus statements considered not only the latest clinical evidence but also the benefits and harms, resource implications, feasibility, acceptability and equity impact of the recommendations. CONCLUSION The statements presented in this paper aim to guide clinicians based on the most updated evidence and collective expert opinion from sleep specialists in Singapore. These recommendations should augment clinical judgement rather than replace it. Management decisions should be individualised, taking into account the patient's clinical characteristics, as well as patient and caregiver concerns and preferences.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective To explore the optimal morning discharge time and pipeline disinfection frequency of the fi-nal rinse water from the endoscopy center according to the microbial culture results.Methods Different morning discharge timing and number of bacterial colonies in the pipeline for the final rinse water from the endoscopy center of a hospital in Jiangsu Province were monitored.Microbial detection was conducted on water samples collected from the two final rinse water sampling sites in the endoscopy room after 0,1,3,5,and 7 minutes of discharge,respec-tively(100 mL each,continuously monitored for 35 days,with 70 samples at each time point)to explore the optimal discharge timing.The optimal disinfection frequency of pipelines for purified water was explored according to the determined optimal morning discharge timing.Two samples were taken daily from 2 sampling sites after pipeline disinfection and continued for 5 weeks,resulting in 70 samples in total.Results Sampling and monitoring of the fi-nal rinse water at different morning discharge time points showed that the median numbers of bacterial colonies at 0,1,3,5,and 7 minutes were 745.00(373.00,1 452.50),150.00(96.75,235.75),44.00(38.00,48.00),12.00(5.00,18.00),and 6.00(4.00,9.00)CFU/100 mL,respectively.Except the difference between the 5 minute group and the 7 minute group(P＞0.05),differences among all the other groups were statistically significant(all P＜0.05).The median of the 0,1,3,and 5 minute groups was＞10 CFU/100 mL,while the median of the 7 mi-nute group was＜10 CFU/100 mL,within the qualified range.The discharge time was therefore determined to be 7 minutes.The average numbers of bacterial colonies from the final rinse water samples taken at different time points after pipeline disinfection(1,2,3,4,and 5 weeks after disinfection)were(4.21±0.86),(4.43±0.71),(6.00±0.56),(6.43±0.45),and(13.57±1.03)CFU/100 mL,respectively.The qualification rates of pipeline in terms of bacterial colony were 100％,100％,100％,100％,and 28.57％,respectively.The differences of average num-bers of bacterial colonies from the final rinse water samples taken at different time points after pipeline disinfection were statistically significant(P＜0.001).The average number of bacterial colonies 5 weeks after pipeline disinfec-tion was different from those after 1,2,3,and 4 weeks,with statistically significant differences(all P＜0.05),while no statistically significant differences among the other groups were observed(all P＞0.05).The optimal disin-fection frequency for the purified water pipeline was once every 4 weeks.Conclusion The final rinse water remai-ning in the terminal of pipeline is contaminated to a certain degree.It is recommended to discharge water in the morning for 7 minutes before using it,and disinfect the purified water pipeline every 4 weeks.

Since the end of 2019,severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection has swept the world,bringing great harm to human society and significantly increasing the health burden.Due to stron-ger infectivity,faster transmission,and higher reinfection rate of the Omicron variant,it has now replaced the Delta variant as the main epidemic strain for both imported and local outbreaks in China.Chinese Diagnosis and treatment protocol for SARS-CoV-2 infection(10th trial version)emphasizes"strengthening the protection of key popula-tions,"which includes the increasing number of immunocompromised population.These people have a high inci-dence of severe diseases and a high fatality rate after infected with SARS-CoV-2,and belong to the high-risk popula-tions of severe or critical diseases.Moreover,due to underlying diseases,these people take immunosuppressants and other related drugs chronically.The interactions between anti-SARS-CoV-2 infection treatment drugs and origi-nal drugs are complicated,thus bring significant challenges to the treatment after the SARS-CoV-2 infection.Cur-rently,there is a lack of guidelines or consensus on the diagnosis and treatment of SARS-CoV-2 infection among im-munocompromised population.Therefore,the Guangzhou Institute of Respiratory Health and National Center for Respiratory Medicine organized experts from multiple disciplines(respiratory and critical care medicine,organ transplantation,rheumatology and immunology,hematology,infection,critical care medicine,etc.)in China.Af-ter multiple rounds of discussions,13 items of recommendations are made as the reference for peers based on evi-dence-based medical evidence,so as to provide a theoretical and practical reference for the diagnosis and treatment strategies of this population.

OBJECTIVE: To analyze and compare the effects of leukapheresis on hemostatic function in patients with hyperleukocytic leukemia. METHODS: A total of 139 patients with AML, ALL and CML who underwent leukapheresis from June 2009 to February 2020 and did coagulation test before and after operation were included in this study. The clearance efficiency of each group and the difference among three groups were evaluated, as well as hemostatic function including platelet counts, coagulation indicators, CDSS score and incidence of adverse events. The difference of hemostatic function caused by leukapheresis in different leukemia patients were compared. RESULTS: After leukapheresis, the WBC counts were decreased significantly in the three groups of patients (P<0.001), and the clearance efficiency was highest in ALL patients. However, the platelet counts also were decreased significantly (AML:P＜0.001, ALL: P＜0.001, CML: P＜0.01) in the three groups of patients, particularly for acute leukemia patients with a positive correlation with WBC clearance efficiency(r=0.284). After leukapheresis, fibrinogen decreased, PT and APTT prolonged. For acute leukemia patients, higher CDSS score was related to an elevated incidence of bleeding events (P<0.05). CONCLUSION Leukapheresis is an effective method to decrease the leukemic burden, but it is necessary to monitor the impact on hemostatic function. It is recommended to assess the CDSS socre for acute leukemia patients, in order to identify the predictive value for bleedings.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

Objective:Through the preparation of Alzheimer's disease （AD） rat model， the effect of Yuanzhisan on the expression of Ghrelin was observed， and the possible mechanisms in preventing and treating AD were discussed. Method:A total of 120 SD rats were randomly divided into sham-operated group， model group， donepezil group（1.02 mg·kg^-1）， and high， medium and low-dose Yuanzhisan groups （12，6，3 g·kg^-1）， with 20 rats in each group， including half male and half female. The rats in sham-operated group were injected with normal saline （NS）， and the rats in other groups were injected with β-amyloid 1-40 （Aβ_1-40） in hippocampus to induce the AD rat model. During the 10-week continuous gavage， the food intake of rats in each group was observed and recorded. After the end of gavage， learning and memory abilities of rats were tested by Morris water maze. The whole brain and the gastric body and antrum were collected， the pathologic changes in the CA1 area of hippocampus was assessed by hematoxylin-eosin （HE） staining， and the expression of Ghrelin was detected by immunohistochemistry. Result:Compared with the sham-operated group， the escape latency time of model group rats increased （P<0.01），while times across platform， retention time in effective area and movement distance decreased （P<0.01）. The disorder of neurons， the decrease of the neuronal number， and the pyknosis of nucleus were observed in hippocampal CA1 area. The food intake of male and female rats decreased significantly （P<0.05，P<0.01）. The expression of Ghrelin in hippocampal CA1 area and gastric mucosa decreased significantly （P<0.01）. Compared with the model group， the escape latency time of rats in each treatment group was significantly shortened （P<0.05，P<0.01），whereas times across platform， retention time in effective area and movement distance increased （P<0.05，P<0.01）. The pathologic change was improved markedly， and the daily food intake of rats in high and medium-dose Yuanzhisan groups increased significantly （P<0.05，P<0.01）. The protein expression of Ghrelin in hippocampal CA1 area and gastric mucosa increased significantly in each Yuanzhisan group （P<0.05，P<0.01）. Conclusion:Yuanzhisan can effectively improve the learning and memory abilities of AD rats and increase the daily intake， which may be related to its up-regulation of Ghrelin content in hippocampal CA1 area and gastric mucosa.
