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 develop a nomogram diagnostic model to differentiate peripheral small cell lung cancer(PSCLC)from peripheral lung adenocarcinoma(PADC)using clinical and multi spiral computed tomography features.Methods A retrospective analysis was conducted on the CT characteristics and clinical presentations of 50 PSCLC and 100 PADC.Univariate and multivariate logistic regression analyses were employed to identify significant features.A nomogram was constructed to quantify the influencing factors.The efficacy and clinical applicability of the model were assessed using the receiver operating characteristic(ROC)curve,calibration curve,and decision curve analysis(DCA).Results Smoking,neuron-specific enolase(NSE),smooth margin,spindle/branching shape,and lymphadenopathy were independent risk factors for PSCLC(P＜0.05),whereas rough margin and lobulation sign were independent risk factors for PADC(P＜0.05).The nomogram model demonstrated high diagnostic efficacy,and the calibration curve exhibited a good degree of calibration(Brier=0.079).The DCA indicated that the nomogram model possesses substantial clinical utility.Conclusion The nomogram model developed based on six indicators,including smoking,NSE≥17 ng/mL,margin characteristics,spindle/branching shape,lobulation sign,and lymphadenopathy can well distinguish PSCLC from PADC.

Objective To examine the diagnosis and treatment of disseminated infection caused by Enterocytozoon bieneusi in a child with leukemia and improve the awareness of the pathogen in clinical and laboratory practice.Methods A case of disseminated infection caused by Enterocytozoon bieneusi in a child with leukemia in Shanghai Children's Hospital was retrospectively analyzed,including diagnosis and treatment details.Similar cases were identified from PubMed,Wanfang Data,VIP,and CNKI databases since database establishment until June 30,2024,using search terms"Enterocytozoon bieneusi".The relevant literature was reviewed.Results This child had acute lymphoblastic leukemia as the underlying disease and was admitted to hospital for antimicrobial treatment due to fever and abdominal discomfort.The case was considered bacterial infection complicated with Enterocytozoon bieneusi infection,confirmed by detection of Klebsiella pneumoniae in blood and detection of Enterocytozoon bieneusi in blood and ascites by metagenomic next-generation sequencing(mNGS).The treatment was switched to tigecycline plus trimethoprim-sulfamethoxazole at a sufficient dose,which resulted in resolution of symptoms.Six months later,the patient suffered from acute lymphoblastic leukemia and bone marrow depression,Enterocytozoon bieneusi disseminated infection,septic shock.Her family gave up treatment and the child died.Literature review indicated that most patients infected with Enterocytozoon bieneusi had underlying conditions such as organ transplantation,AIDS,and leukemia associated with poor immunity.The onset symptoms are diarrhea,abdominal discomfort,and fever.Enterocytozoon bieneusi was detected by using methods such as modified Masson's trichrome stain,fluorescent calcofluor white staining,molecular detection techniques,and immunofluorescence.The patients were treated with drugs such as albendazole,nitazoxanide,fumagillin,and trimethoprim-sulfamethoxazole.Conclusions Enterocytozoon bieneusi is an opportunistic pathogenic fungus that infects immunocompromised patients and can cause abdominal discomfort,diarrhea,fever,and even disseminated infection and death.Conventional laboratory methods cannot culture Enterocytozoon bieneusi.Molecular detection techniques can be used to identify the pathogen early.

Purpose To investigate the clinicopathologic,immunophenotypic features,genetic alterations and prognosis of melanotic Xp11 neoplasms/melanotic TFE3-rearrangement neo-plasms.Methods Five cases were selected from the Depart-ment of Pathology,Union Hospital,Huazhong University of Sci-ence and Technology from November 2018 to July 2023.The clinicopathologic,immunohistochemical,FISH assays,next-generation sequencing(NGS)and follow-up details were collect-ed.Results There were 1 male and 4 females,with their ages ranging from 16 to 59 years(mean 28.2 years).The maximum diameters of the masses were 3-6 cm(average 4.7 cm).The tumors located in right kidneys(3 cases),tubal interstitium(1 case)and pelvis(1 case).Microscopically,most tumors shared similar morphology such as nested,acinar structures sep-arated by a delicate vascular network.Epithelioid tumor cells presented with clear to granular eosinophilic cytoplasm.Lym-phocytic infiltration was seen in the background;melanin depo-sition was noted in the cases;neoplastic necrosis was detected in 4 cases.Mitotic activity was low with 5 cases showing＜3/10 HPF.Intravascular tumor thrombus was detected in 2 cases,no lymphovascular and nerve invasions were detected in other 3 ca-ses.Immunohistochemically,all 5 cases expressed TFE3 dif-fusely,and expressed HMB45,Melan A to varying degrees,CK(AE1/AE3),CK7,EMA,PAX8,TFEB,S-100,SOX10,SMA,desmin were all non-reactive in the 5 cases.The Ki67-la-beling index was＜20％.TFE3 separation signal in 4 cases were detected by FISH,1 case was interpreted as negative due to atypical signal which was confirmed by next-generation se-quencing(NGS)assay as RBM10-TFE3.Clinical follow-up was available for five patients for 2-60 months,in which four pa-tients were alive with no evidence of disease after initial resec-tion,and one patient with thoracic spine metastasis was currently in stable condition.Conclusion Melanotic Xp1 1 neoplasms/melanotic TFE3-rearrangement neoplasms has unique morpholog-ic,immunophenotypic and genetic characteristics.It might be reclassified into a distinctive malignant mesenchymal tumor enti-ty.

This study was designed to evaluate the correlation between immune antibodies and pelvic inflammatory disease(PID)using retrospective analysis.Cases were selected from 171 patients who met the diagnosis of PID in Liuzhou People's Hospital of Guangxi Province from January 2022 to March 2023,and the PID patients were further divided into simple PID group(53 cases)and in PID combined with reproductive tract infection group(118 cases)according to the presence or absence of reproductive tract infections,while 83 cases of women who did not meet the specific diagnostic criteria of PID and did not have reproductive tract infections were selected as the control group during the same period.The positive rate of immune antibodies in the three groups were observed and compared to explore the relationship between immune antibodies and PID.Data showed that the positive rates of immune antibodies were significantly higher in the PID alone group and the PID combined with reproductive tract infection group than that in the control group.Furthermore,the positive rate of immune antibody TPOAb was significant difference in the PID combined with reproductive tract infection group and the PID alone group(P<0.05).In conclusion,TPOAb is closely associated with reproductive tract infections.

Objective To investigate the effect and mechanism of emodin on focal cerebral ischemia in rats based on myeloid differentiation factor 88(MyD88)/extracellular signal-regulated kinase(ERK)pathway and nuclear factor-κB(NF-κB)nuclear translocation.Methods SD rats were randomly divided into sham operation group,model group and emodin group,with six rats in each group.The rat model of transient middle cerebral artery occlusion(tMCAO)was established by middle cerebral artery embolization.Rats in the emodin group were given 40 mg·kg-1 emodin by gavage for three times at 72,48 and 24 hours before modeling.At 24 hours after modeling,the neurological function of rats was scored.TTC staining was used to detect the area of cerebral infarction.HE staining was used to observe the morphological changes of brain tissue.The mRNA expression levels of MyD88 and tumor necrosis factor-α(TNF-α)in brain tissue were detected by RT-qPCR.The expression levels of MyD88,ERK,p-ERK and TNF-α in brain tissue were detected by Western Blot.The protein expression of NF-κB in brain tissue was detected by immunofluorescence.Results Compared with the sham operation group,the neurological function score of the model group was significantly increased(P＜0.01),and the cerebral infarction area was significantly increased(P＜0.01).In the cortical area of the ischemic penumbra,cell necrosis,abnormal cell morphology,nuclear fragmentation and atrophy,and the number of cells decreased significantly;the mRNA expression levels of MyD88 and TNF-α in brain tissue were significantly increased(P＜0.01,P＜0.001),the protein levels of MyD88,p-ERK/ERK and TNF-α were significantly increased(P＜0.05,P＜0.01,P＜0.001),and the proportion of NF-κB into nuclear cells was significantly increased(P＜0.001).Compared with the model group,the neurological function score of rats in the emodin group was significantly decreased(P＜0.05),and the area of cerebral infarction was significantly reduced(P＜0.05).The number and morphology of neurons in the ischemic penumbra cortex were restored to a certain extent.The mRNA expression levels of MyD88 and TNF-α in brain tissue were significantly decreased(P＜0.05,P＜0.01),the protein levels of MyD88,p-ERK/ERK and TNF-α were significantly decreased(P＜0.05),and the proportion of NF-κB into nuclear cells was significantly decreased(P＜0.001).Conclusion Emodin has a preventive and protective effect on rats with focal cerebral ischemia,which may be related to its inhibition of MyD88 activation,ERK phosphorylation and NF-κB nuclear translocation,and then down-regulation of inflammatory cascades and secretion of pro-inflammatory factors such as TNF-α,thereby exerting anti-inflammatory effects.

Objective To construct a novel enzyme-free colorimetric biosensor(T-CHA)based on tri-ple-helix molecular probe(THMP)and catalytic hairpin assembly(CHA)reaction for visual detection and precise quantitative analysis of low-abundance alpha-fetoprotein(AFP).Methods The absorbance produced by AFP induced T-CHA system was recorded by gel electrophoresis and ultraviolet-visible spectrophotometer to evaluate the feasibility of T-CHA strategy.The molar concentration ratio of THMP and CHA,reaction time of CHA,temperature and pH value of buffer solution were optimized respectively.The color reaction of T-CHA was induced by different concentrations of AFP to explore the detection efficiency of T-CHA.Results Under the op-timal experimental conditions,the logarithmic values of AFP at different concentrations showed a linear rela-tionship from 5 μg/mL to 10 ng/mL,and the detection limit was 2.29 μg/mL.The T-CHA system could com-plete accurate quantitative analysis of low abundance AFP and visual free-labeled detection within 105 min,moreover the sensitivity of T-CHA was superior to that of ELISA.Conclusion Utilizing the low background leakage of THMP and the high catalytic efficiency of CHA,the T-CHA system could realize the early accurate diagnosis of hepatocellular carcinoma,moreover which has a certain application prospect in the real time detec-tion.

To summarize the nursing experience of a patient with schizophrenia complicated by severe neurodeptic malignant syndrome.Nursing points include:to emphasize monitoring of antipsychotic medications to detect the onset of neurodeptic malignant syndrome as early as possible;to leverage the multidisciplinary team for rapid initiation of acute phase management interventions;to combine multimodal cooling to help rewarm the patient;to implement the stepwise intervention program to promote recovery of bowel function;to emphasize family supportive therapy to restore social functioning;to continue case management by developing a multidisciplinary follow-up plan.After careful management and care by the multidisciplinary team,the patient was successfully discharged from the hospital after a total stay of 47 days.After 3 months of follow-up,the patient's daily life was basically back to normal.
