Effective decompression and fixation of nasal catheter are important contents in nursing work. The fixation device is used for preventing falling and displacement of the nasal catheter. This study introduces the design and use of a fixation device for nasal catheter, which has the characteristics of decompression, firmness and comfort, and can solve the problem of skin pressure injury caused by wearing the catheter for a long time, and increase the comfort of patients.

Background As an objective index to evaluate chronic stress, allostatic load (AL) is associated with adverse pregnancy outcomes. At present, there are few longitudinal studies to analyze the influencing factors of AL among pregnant women. Objective To investigate the status of AL and its influencing factors in pregnant women at different trimesters. Methods This study was designed as a prospective study. Questionnaire survey, physical examination and laboratory examination were administered to 152 women in the first (≤14 weeks), second (23-27 weeks) and third (30-34 weeks) trimesters of pregnancy collected in the obstetrics outpatient clinics of the 901 Hospital, Joint Logistic Support Force of the Chinese People's Liberation Army, Jin'an Maternal and Child Health Care Hospital from November 2021 to November 2022 by using convenience sampling method. The Edinburgh Postpartum Depression Scale (EPDS) was used to assess the depression during pregnancy. Referring to previous studies, the relevant assessment indexes of metabolic system, cardiovascular system, and immune system were used to calculate the total score of AL, and AL≥3 score was used as a criterion for determining high AL level at different trimesters of pregnancy. Multivariate Logistic regression analysis was used to explore the influencing factors of AL in the first, second and third trimesters. Results Among 152 pregnant women, the mean total AL score was (2.06±1.68), (2.07±1.84) and (2.07±1.68) in the first, second and third trimesters; 52 (34.2%), 54 (35.5%) and 50 (32.9%) women were in high level of AL (total score of AL≥3) in the first, second and third trimesters. The results of multivariate Logistic regression analysis showed that occupations {business service employees〔OR=0.229, 95%CI (0.062, 0.845), P=0.027〕, office staff〔OR=0.164, 95%CI (0.051, 0.528), P=0.002〕, professional and technical personnel〔OR=0.278, 95%CI (0.099, 0.784), P=0.015〕}, unemployment〔OR=5.516, 95%CI (1.044, 29.144), P=0.044〕and depression〔OR=6.241, 95%CI (1.403, 27.757), P=0.016〕were the influencing factors of AL in the first trimester. Age〔OR=1.098, 95%CI (1.002, 1.202), P=0.045〕and AL in the first trimester〔OR=9.965, 95%CI (4.402, 22.561), P

Background The incidence of adverse pregnancy outcomes has remained high in recent years, which poses a serious threat to maternal and neonatal life and health. Chronic stress is known to be a risk factor for adverse pregnancy outcomes, while the relationship between allostatic load (AL) as a composite physiological index of chronic stress, and adverse pregnancy outcomes has not been clarified. Objective To explore the effect of AL on adverse pregnancy outcomes in women in late pregnancy. Methods Women in late pregnancy who met the study requirements were recruited as study subjects by using the convenience sampling method from November 2021 to November 2022 in the obstetrics outpatient clinics of the 901 Hospital, Joint Logistic Support Force of the Chinese People's Liberation Army, Jin'an Maternal and Child Health Care Hospital. Basic information such as general and obstetric data were collected through questionnairs, biological indicators were collected through physical examination and laboratory tests, and AL scores of the study subjects were calculated by referring to AL-related literature; pregnancy outcome information was obtained by reviewing the hospital electronic medical record system. Multivariate Logistic regression analysis was used to explore the effect of AL on adverse pregnancy outcomes in women in late pregnancy. Results A total of 354 women in late pregnancy with an average age of (29.3±4.1) years and upper quartile of AL total score of 3 were included in this study. The upper quartile of the total AL score of the study subjects was used as the high-risk threshold, and they were divided into low-level AL (AL

Background Chronic stress is known to be associated with the onset of depression, allostatic load (AL) may play a significant role in the pathogenesis of depression as a comprehensive physiological index to evaluate response to the chronic stress. Objective To identify the association between AL level and depression among women in early pregnancy. Methods 630 Women in early pregnancy who underwent prenatal examination in the 901 Hospital, Joint Logistic Support Force of the Chinese People's Liberation Army, Jin'an Maternal and Child Health Care Hospital from November 2021 to June 2022 were selected as the research subjects by using convenience sampling method, and were divided into the depression group (n=162) and non-depression group (n=468) according to presence or absence of depression. The general information questionnaire, Pregnancy-specific Anxiety Questionnaire and Edinburgh Postnatal Depression Scale were used for questionnaire survey, AL-related data were collected by physical examination and laboratory tests. Multivariate Logistic regression model was used to analyze the association between AL level and depression among women in early pregnancy. Results A total of 630 pregnant women in early pregnancy were enrolled with the depression incidence of 25.7% (162/630) , including 427 pregnant women (67.8%) with low AL level (AL
