ObjectiveTo explore the impacts of material type and loading volume of rigid containers on the hydrogen peroxide low temperature plasma sterilization of thoracoscopic instruments, to identify the best rigid containers and loading volume of thoracoscopic instruments. MethodsThoracoscopic instruments sterilized by STERRAD^® 100NX hydrogen peroxide low temperature plasma in Shanghai Pulmonary Hospital affiliated to Tongji University from August to September 2024 were selected as the research items. According to the material of rigid containers, the instruments were divided into polyethylene case group (A), stainless steel case group (B) and silicone resin case group (C). In terms of the loading volume, the rigid containers were divided into (loading capacity <80%) groups of 8, 10 and 12 instruments. The results of physical monitoring, the first type of chemical indicator card monitoring, and the five types of card luminal chemical process challenge device (PCD) monitoring of the 9 groups of A8, A10, A12, B8, B10, B12, C8, C10 and C12 were compared and evaluated. ResultsCompared to A8, A10 A12, C8, C10 or C12 groups, the thoracoscope instruments in the stainless steel containers in B8, B10 or B12 group had higher hydrogen peroxide concentrations and shorter elapsed time in the pressure check phases 1 and phases 2, with the differences statistically significant (P<0.05), followed by the silicone resin case group and the polyethylene case group. The nine groups of physical parameter monitoring, the first type of chemical indicator monitoring, and the five types of chemical PCD monitoring for lumen sterilization achieved 100% qualification rates, and there were no significant differences in the qualified rates of sterilization among the 9 groups (P>0.05). ConclusionWhen using hydrogen peroxide low temperature plasma to sterilize thoracoscopic instruments, it is recommended to use stainless steel or silicone resin rigid containers with a controlled loading capacity (≤12) to ensure optimal sterilization quality.

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 efficacy and safety of fecal microbiota transplantation (FMT) in the treatment of irritable bowel syndrome (IBS), and to explore the effects of FMT on the gut microbiota of IBS patients.Methods:From September 2016 to August 2017, at Guangzhou First People′s Hospital, 28 hospitalized IBS patients who underwent FMT treatment were enrolled. Before FMT, four and 12 weeks after FMT, all the IBS patients completed the irritable bowel syndrome quality of life scale (IBS-QOL), irritable bowel syndrome severity scoring system (IBS-SSS) and gastrointestinal symptom rating scale (GSRS). 16S rDNA sequencing was performed before FMT and four weeks after FMT. The effects of FMT on gut microbiota diversity and microbiota structure of IBS patients were analyzed respectively from the level of phylum, family and genus, and linear discriminant analysis effect size (LEfSe) was further used to screen the different bacteria. Paired t test and paired rank sum test were used for statistical analysis. Results:Twelve weeks after FMT, the scores of the six dimensions of IBS-QOL including dysthymia, behavioral disorder, auto imagery, health concerns, eating avoidance, and relationship expansion were all lower than those before FMT (43.750, 22.656 to 56.250 vs. 48.438, 32.031 to 60.938; 37.500, 18.750 to 56.250 vs. 46.429, 21.429 to 62.500; 31.250, 14.063 to 42.188 vs. 31.250, 18.750 to 50.000; 41.667, 27.083 to 56.250 vs. 50.000, 41.667 to 66.667; 54.167, 43.750 to 72.917 vs. 66.667, 58.333 to 83.333; 8.333, 0.000 to 33.333 vs. 16.667, 8.333 to 33.333, respectively), and the differences were statistically significant ( Z=-2.157, -3.429, -2.274, -3.197, -3.042 and -2.329, all P<0.05). Twelve weeks after FMT, the scores of the two dimensions of IBS-QOL including behavioral disorder and relationship expansion were both lower than those of four weeks after FMT (37.500, 18.750 to 56.250 vs. 39.286, 19.643 to 62.500 and 8.333, 0.000 to 33.333 vs. 16.670, 2.083 to 41.667, respectively), and the differences were statistically significant ( Z=-1.998 and -2.110, both P<0.05). Four and 12 weeks after FMT, the scores of IBS-SSS and GSRS were both lower than those before FMT ((190.32±106.51), (201.43±102.48) vs. (245.93±86.10) and 5.50, 4.00 to 9.00 and 5.50, 4.00 to 8.75 vs. 7.00, 6.00 to 9.75), and the differences were statistically significant ( t=4.402 and 3.848, Z=-3.081 and -3.609; all P<0.01). No serious adverse reactions occurred in the patients after FMT. At the phylum level, after FMT the abundance of Verrucomicrobia in the feces of IBS patients was richer than that before FMT (6.74% vs. 0.37%); at the family level, after FMT the abundance of Verrucomicrobiaceae in the feces of IBS patients was richer than that before FMT (6.74% vs. 0.37%); at the genus level, after FMT the abundance of Akkermansia was richer than that before FMT (6.74% vs. 0.37%); and the differences were statistically significant (all Z=-2.589, all P=0.010). The results of LEfSe method indicated that four weeks after FMT the abundance of Akkermansia in the gut microbiota of IBS patients was richer than that before FMT (6.74% vs. 0.37%), and the difference was statistically significant (linear discriminant analysis value=4.5, P=0.049). Conclusions:FMT is safe and effective in the treatment of IBS. The mechanism may be through upregulating the diversity of gut microbiota and changing the structure of gut microbiota of IBS patients.

Early recognition and treatment for early warning electrocardiogram (ECG) of sudden death are very important to prevent and treat malignant arrhythmia and sudden death. Previous studies have found that R-on-T and T wave alternation, and QT interval prolongation are closely related to malignant arrhythmia or sudden death, which are included in the critical value of ECG.By analyzing the ECG characteristics of 4 patients with sudden death, we found that although the causes of the patients were different, there were transient prolongation of QT interval after premature contraction in 12 lead ECG, followed by malignant arrhythmia or sudden death. Thus, we thought that the transient prolongation of QT interval after premature contraction had a high value for warning malignant arrhythmia or sudden death. This phenomenon should be paid enough attention to reduce the risk of sudden death.

Objective:To explore the effect of dynamic multi-dimensional management model based on informatization on improving the home self-care of lymphedema patients.Methods:A total of 80 patients who received lymphedema combined detumescence treatment from January 2018 to June 2018 were selected as the control group.From July 2018 to December 2018, 80 patients were treated as the intervention group, and the whole process was managed on the basis of the control group using the dynamic multidimensional management mode based on informatization. Patients' compliance and quality of life were compared between the two groups.Results:The intervention group patients' compliance was better than control group, correctly measure the circumference of limbs, the law of life that occupy the home was good, correct manual lymph drainage direction, bandages, functional exercise, 18 standards compliance, respectively, 95.0%(76/80), 87.5%(70/80), 97.5%(78/80), 95.0%(76/80), 100.0%(80/80), 87.5%(70/80), better than that of control group were 77.5%(62/80), 75.0%(60/80), 80.0%(64/80), 70.0%(56/80), 75.0%(60/80), 50.0%(40/80), difference was statistically significant ( χ2 values were 4.103-26.182, P<0.05 or 0.01). After a course of treatment and 3 months of home-based self-care, the scores of role function, physical function, emotional function and social function of the quality of life in the intervention group were (75.44 ± 2.78), (80.11 ± 3.01), (78.25 ± 2.78), (79.93 ± 5.43), which were better than those of the control group (66.25 ± 2.58), (75.88 ± 3.57), (65.16 ± 2.47), (62.78 ± 4.01), with statistically significant differences ( t values were 8.09, 31.50, P<0.01). Conclusions:The dynamic multi-dimensional management model based on informationization and doctor-patient participation can improve the compliance and quality of life of patients participating in home-based self-care and better meet the needs of home-based nursing.

Objective To explore the limits of fluid-inversion prepared diffusion weighted imaging (FLIPD) in detection of acute cerebral ischemic lesions.Methods From January 2012 to March 2014,forty-nine patients (33 males,16 females,age (55.6± 12.3) years) clinically diagnosed as transient ischemic attack (TIA) were included.Patients underwent brain MRI (conventional diffusion weighted imaging (DWI) and FLIPD) within 3 d after the onset of TIA.The detection ability of MRI with the two sequences was compared,and the relative signal intensity (rSI) and apparent diffusion coefficient (ADC) of acute ischemic lesions based on two sequences were compared.Kappa test and two-sample t test were used to analyze the data.Results A total of 87 acute ischemic lesions were detected in 21 patients by conventional DWI,and 54 were detected in 19 patients by FLIPD (Kappa=0.916,P＜0.05).The rSI of ischemic lesions on FLIPD was significantly lower than that on conventional DWI (1.37±0.22 vs 1.57±0.26;t=6.647,P＜0.001).The ADC value of ischemic lesions on FLIPD was slightly lower than that on conventional DWI:(0.54 ±0.10) ×10-3 mm2/s vs (0.57±0.13)×10-3 mm2/s (t=2.120,P＜0.05).The missed lesions on FLIPD were located in the white matter (n =18),cerebellum and brainstem (n =8),and the cortex (n =7).Conclusions A slight diffuse abnormality may be missed on FLIPD,so this method is not suitable for the detection of acute ischemic lesions.FLIPD technology still needs improvement.

Objective To explore the effects of seven-step complex decongestion therapy (CDT) on post-operative upper limb lymphede-ma of breast cancer. Methods From August, 2015 to September, 2016, 71 patients with upper limb lymphedema after breast cancer surgery accepted CDT for 20 days, including skin care, opening of lymphatic pathway, relief of scar tissue, manual lymphatic drainage, bandage compression, air pressure wave therapy and functional exercise. The circumference of eight sites of both limbs was measured and the differ-ences were calculated before treatment, and one, five, ten, fifteen and twenty days of the treatment. Results The differences of circumfer-ence increased one to 15 days of the treatment (Z>2.03, P<0.05), and decreased 20 days of the treatment (Z=3.01, P<0.01). Conclusion CDT is effective on lymphedema after breast cancer surgery for 20 days of a course, but may worsen in the first 15 days, which may be relat-ed to acute stress response or redistribution of lymph.

Objective To explore the effect of manual lymphatic drainage on prevention of postoperative axillary web syndrome of breast cancer. Methods From June to December, 2015, 400 breast cancer patients after modified radical mastectomy were randomly divided into control group (n=200) and intervention group (n=200). The control group accepted routine functional exercise on affected upper limbs, while the intervention group accepted manual lymphatic drainage in addition. The incidence of axillary web syndrome in both groups was compared one, two and three months after operation. Results The incidence of axillary web syndrome was less in the intervention group than in the control group in all the time points after operation (χ2>6.17, P<0.05). Conclusion Manual lymphatic drainage can effectively pre-vent axillary web syndrome in patients with breast cancer after modified radical mastectomy.
