Objective:To develop a knowledge, attitude, and practice (KAP) questionnaire on oral health for pregnant women and to evaluate its reliability and validity.Methods:Following the methodological framework of DeVellis's scale development guidelines, the initial version of the questionnaire was constructed through literature review, focus group discussions, and two rounds of expert consultations. A convenience sample of pregnant women attending the obstetrics outpatient clinic at Peking University People's Hospital was surveyed from September to October 2023 for psychometric evaluation.Results:A total of 200 questionnaires were distributed and all were returned with valid responses, yielding a 100.00% (200/200) response rate. The finalized KAP questionnaire consisted of 32 items across three dimensions: oral health knowledge, attitude, and behavior among pregnant women. The scale-level content validity index universal agreement ( S- CVI/UA) was 0.843, and the item-level CVI ( I- CVI) ranged from 0.889 to 1.000. Cronbach's α coefficients for the three dimensions ranged from 0.716 to 0.911, and test-retest reliability coefficients ranged from 0.744 to 0.952. Conclusions:The developed KAP questionnaire demonstrates good content validity and reliability and can be used to assess the level of oral health knowledge, attitude, and behavior among pregnant women.

OBJECTIVE To investigate the management status of small pressure steam sterilizers in dental institu-tions across seven major regions of China and provide references for establishing standardized monitoring and eval-uation protocols for sterilization efficacy.METHODS From Aug.to Nov.2023,a convenience sampling method was employed to select 885 dental institutions of various levels from seven geographical regions.An online survey using a self-designed questionnaire was conducted to assess the management status of small pressure steam steri-lizers in dental institutions.RESULTS A total of 885 questionnaires were distributed,with 770 valid responses col-lected,covering 770 dental institutions at all levels.The survey involved 2 056 small pressure steam sterilizers,of which 43.14％were pre-vacuum type and 89.40％were benchtop models.Tertiary dental institutions had the high-est proportion of imported small pressure steam sterilizers(60.15％),with most devices in use for 5-10 years(36.88％).Secondary and low er-level institutions predominantly used domestically produced small pressure steam sterilizers(74.60％),which used for 3-5 years accounting for the highest proportion(34.29％).While 85.58％of dental institutions employed dedicated sterilization personnel,only 45.84％performed proper maintenance for small pressure steam sterilizers.Training rates were 80.00％for department of stomatology in ungraded general hospitals and primary medical institutions,76.19％in prejob and 71.43％during the work for department of sto-matology in primary clinics,respectively.CONCLUSIONS Although most dental institutions demonstrate sound policy formulation,challenges persist in equipment maintenance,policy implementation and grassroots training.Future efforts should be made on strengthening maintenance and inspection of equipment,enhancing sys-tem supervisory mechanisms,and optimizing training systems to ensure dental treatment safety.

Objective:To summarize the research on oral health education for pregnant women.Methods:The literature was described and analyzed using a scoping review method. Seven databases, such as PubMed, Embase, Web of Science, China National Knowledge Infrastructure, and WanFang Data, were electronically searched, and the search period was from database establishment to October 30, 2023.Results:A total of 43 articles were included. The implementers of health education were mainly dental professionals and prenatal healthcare personnel. The theoretical basis included the health belief model, planned behavior theory, social cognitive model and so on. The methods involved traditional teaching or lectures, family-centered, internet-based, and motivational interviews. The contents contained many aspects of oral health for pregnant women. The evaluation indicators mainly covered oral health knowledge, attitude and practice, and self-efficacy, oral health beliefs, oral health status, the incidence of oral diseases, adverse pregnancy outcomes of pregnant and postpartum women, and childhood caries incidence.Conclusions:We should establish a cooperation team of the Department of Stomatology and Obstetrics and Gynecology, incorporate oral health for pregnant women into prenatal care projects, fully utilize the platform of pregnant women's schools, explore the optimal theoretical basis for oral health education, and improve the content of oral health education for pregnant women.

Sepsis-induced cardiomyopathy is a reversible myocardial dysfunction due to sepsis, which may be severe enough to complicate cardiogenic shock, and without effective drug and with high mortality during the acute phase. A case of sepsis-induced cardiomyopathy complicated with cardiogenic shock was treated in the intensive care unit (ICU) of Shunde Hospital Southern Medical University. A 37 years old female patient was admitted because she had suffered repeated fever for 5 days, chest tightness and abdominal pain for 3 days. At the same time, there were severe cardiac depression and abdominal infection, which could be explained by the monismtheory of sepsis cardiomyopathy. The cardiogenic shock patient was not improved after antibiotic therapy and hemodynamic support, extracorporeal membrane oxygenation (ECMO) support was prescribed. The circulation failure was smoothly got through with ECMO and was transfer from ICU to ordinary ward. Computed tomographic angiography (CTA) of abdominal aorta and colonoscopy indicated lesions of small intestine. The diagnosis of infection and bleeding in ileum diverticulum was confirmed during the operation and the lesions was removed. She recovered and was discharged 1 week after operation. Through the case review, we aim to improve the awareness of sepsis-induced cardiomyopathy and the value of ECMO support in cardiogenic shock.
