Psychological distress in subsequent pregnancy among women with a history of pregnancy loss: A latent profile analysis.

BACKGROUND: Women who have undergone pregnancy loss can experience a range of psychological distress during subsequent pregnancies; however, the outcomes may vary based on individual circumstances. OBJECTIVE: To explore the potential patterns of psychological distress for pregnant women with a history of pregnancy loss, and to investigate the impact of factors related to pregnancy loss on these patterns. METHODS: From October 2022 to August 2023, the participants were recruited from four medical centers in Guangdong Province, China. They completed a questionnaire survey comprising sociodemographic and obstetric characteristics, the Perceived Stress Scale-4 (PSS-4), the Impact of Event Scale-Revised (IES-R), the Pregnancy-related Anxiety Questionnaire-Revised 2 (PRAQ-R2), and the Patient Health Questionnaire-9 (PHQ-9). Latent profile analysis was used to determine optimal patterns of psychological distress. The logistic regression was conducted to assess the associations between the number of pregnancy loss, types of pregnancy loss, inter-pregnancy interval, and distinct psychological distress patterns. RESULTS: A total of 446 pregnant women with a history of pregnancy loss were included for formal analysis. Three distinct profiles were identified, namely the "mild psychological distress" (34.1 %), "moderate psychological distress" (57.8 %), and "severe psychological distress" (8.1 %). Recurrent pregnancy loss was associated with increased risks of both moderate (adjusted odds ratio [aOR] 2.45, 95 % confidence interval [CI]: 1.42-4.24; P = 0.001) and severe psychological distress (aOR 2.93, 95 %CI: 1.25-6.83; P = 0.013). Furthermore, compared to women who conceived after 6 months of pregnancy loss, those who conceived within 6 months of pregnancy loss were more likely to be categorized into the group of moderate psychological distress (aOR 2.00, 95 % CI: 1.21-3.30; P = 0.007). CONCLUSIONS: Approximately two-thirds of pregnant women with a history of pregnancy loss exhibit moderate to severe psychological distress. Such individuals could benefit from early screening and targeted psychological interventions, particularly those who have encountered recurrent pregnancy loss and those who conceive shortly after a pregnancy loss.

Changes in Incidence of Notifiable Infectious Diseases in China Under the Prevention and Control Measures of COVID-19.

Aim: The aim of this study was to analyze the changes in incidence of notifiable infectious diseases in China under the prevention and control measures of COVID-19. Methods: Using descriptive epidemiological methods, data were collected from the official website of the Health Commission of the People's Republic of China, and the prevalence characteristics of notifiable infectious diseases in the country in 2020 were analyzed and compared with the historical data in 2019. Monthly reporting data on influenza and tuberculosis from 2015 to 2019 were also collected. Results: Except for COVID-19, the total number of notifiable infectious diseases cases in 2020 was 6,366,176, a decrease of 41.38% year-on-year compared with 2019. Category B and C notifiable infectious diseases decreased by 14.84 and 54.98% year-on-year, respectively (P < 0.01). The top three incidence rates were influenza (87.63 cases/100,000), hepatitis B (81.36 cases/100,000) and other infectious diarrhea (76.33 cases/100,000). Three types of diseases with the largest decline were influenza (-2,280,502 cases), hand-foot-mouth disease (-1,174,588 cases), and other infectious diarrhea diseases (-275,746 cases). Compared with 2019, respiratory infectious diseases were reported to be in the largest decline in 2020, followed by intestinal infectious diseases, blood-borne and sexually transmitted diseases, natural foci, and insect-borne infectious diseases. The monthly reported incidences of influenza and tuberculosis in 2020 were lower than the average of the previous 5 years. Conclusion: In 2020, the incidence of most notifiable infectious diseases in China showed a downward trend, non-pharmaceutical interventions (NPIs)such as the wearing of masks, frequent hand-washing, more ventilation, less gathering, etc, played an positive role in the prevention and control of respiratory and intestinal infectious diseases. The various public health intervention strategies and measures adopted by China to contain COVID-19 can provide a reference for the prevention and control of infectious diseases in other countries.

Acupoint Massage Therapy Alters the Composition of Gut Microbiome in Functional Constipation Patients.

RESULTS: Results showed the overall structure of gut microbiome has no significant difference between experimental and control groups. In the genus level, the abundance of Pseudobutyrivibrio and Ruminiclostridium is higher in the experiment group than in the control, whereas that of Fusicatenibacter is less. The 16S KEGG function prediction suggested that Parkinson disease, retinol metabolism, and arachidonic acid metabolism could explain the biological function of different gut microbiome. Furthermore, cytokines in the serum showed a correlation with the abundance of Pseudobutyrivibrio in CFC. CONCLUSION: AMT could change the composition of gut microbiome which is associated with cytokines in CFC patients.

Cell count-based parameters and algorithms for thalassaemia trait screening in the southern Chinese population.

INTRODUCTION: Thalassaemia trait (TT) is potential to be missed clinically, especially normocytic thalassaemia. We aimed to establish discriminant functions (DFs) and an algorithm for detecting microcytic or normocytic TT in epidemiological screening. METHODS: The receiver operating characteristics (ROC) curve analysis was used to determine the diagnostic performance of the proposed formulas in differentiating TT and nonthalassaemia (non-TT). DFs combined the two blood count parameters with the highest performance, based on the area under the curve (AUC) value, into mathematical formulas, using logistic regression. The diagnostic efficacy of DFs was subsequently evaluated in 761 participants, and reliability (including adjusted agreement [AA] and Kappa values) and validity (including sensitivity, specificity, likelihood ratio and Youden's Index) were calculated. RESULTS: Among microcytic participants, the proposed DFs showed good diagnostic performance (in females: AUC = 0.892 [DF1 = 0.015 × RDW-CV/RBC - 0.096 × RDW-SD/RBC + 1.29], in males: AUC = 0.861 [DF2=-0.025 × RDW-SD/RBC - 0.035 × MCV/RBC + 1.415]). Youden's Index, AA and Kappa values for microcytic TT detection were 0.72, 0.86, and 0.72 and 0.63, 0.81 and 0.63 for females and males, respectively. In normocytic participants with RDW-CV/RBC ≤ 3.54, DF3=-0.38 × MCH-0.02 × MCHC+17.37 achieved AUC = 0.857 in females, whereas DF4 = 0.007 × MCV-0.113 × MCH+2.829 achieved AUC = 0.969 in males. The Youden's Index, AA and Kappa values for the proposed DFs for thalassaemia detection were 0.69, 0.84 and 0.67 in females, 0.76, 0.91 and 0.71 in males, respectively. CONCLUSION: The proposed DFs performed well in the detection of TT among participants with microcytic and normocytic parameters and could be utilized in epidemiological study for TT.
