Factors affecting nurses' emergency competencies in public health emergency: A cross-sectional study based on the stress-coping adaptation model.

To investigate the factors associated with stress, resilience, coping styles, and emergency competencies when nurses are faced with a public health emergency. This study used a cross-sectional design. Study data came from a survey of 646 nurses who were from a tertiary hospital in Southern China in March-June 2022. Participants responded to self-report questionnaires through a web-based survey. Stress, resilience, emergency competencies, and response to public emergencies were assessed using the Perceived Stress Scale, Connor-Davidson Resilience Scale, the core competencies of nurses in public health emergencies, and a simplified coping style questionnaire. A total of 646 nurses participated in this study. Slightly over half of the participants were ≤30 years old, and almost all were female. Resilience, positive coping, and negative coping were positively correlated with emergency competencies. Multiple linear regression analysis demonstrated that resilience, working years, and participation in the treatment of infectious diseases were significant predictors of emergency competencies. The findings suggest that nurses require additional training in emergency management and clinical practice to enhance their emergency competencies. More interventions and social support should be provided to improve nurses' resilience and positive coping strategies when they encounter public health emergencies.

The symptoms and interval of Omicron SARS-CoV-2 reinfection among healthcare workers in a hospital of Southern China: a cross-sectional study

BackgroundThe prevalence and distinction between first Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and reinfection with the Omicron variant among healthcare workers (HCWs) remain unclear.MethodsA cross-sectional study was conducted at a hospital in Southern China. The study included 262 HCWs who were infected with SARS-CoV-2 between April and June 2023, with 101 cases of first infection and 161 ones of reinfection. Student’s t-test, Analysis of Variance (ANOVA), and Mann-Whitney U tests were used based on the distribution of quantitative variables. Pearson’s chi-square and Fisher’s exact tests were used based on the expected frequencies of categorical variables.ResultsThe reinfection rate among HCWs was 11.5% (161/1406). The majority of the infected HCWs were female (212/262, 80.9%, first infection vs. reinfection: 76.2% vs. 83.9%). The nursing staff, had the highest percentage of SARS-CoV-2 infection (42.0%), especially of its reinfection (47.8%). Out of the 262 infected individuals, 257 had received SARS-CoV-2 vaccination, primarily inactivated vaccines (243/257, 91.1%). The first infection group, which received four doses (24, 23.8%), was significantly higher than that in the reinfection group (6, 3.7%) (P < 0.001). The proportion of asymptomatic infections among HCWs in the two groups was 1.0% and 1.2%. The main symptoms during the first infection and reinfection were fever (83.2% and 50.9%) and sore throat (78.2% and 77.0%). There were significant differences in the prevalence of fever (83.2% vs. 50.9%), rhinorrhea (45.5% vs. 60.9%) and myalgia (56.4% vs. 37.9%) between the first infection and reinfection (P < 0.05). The average interval for SARS-CoV-2 reinfection was 149.9 (range: 114–182, SD = 11.9) days. Notably, physicians had the shortest average interval of 142.8 (8.8) days, while management and administrative staff had the longest average interval of 153.8 (13.5) days.ConclusionsAlthough the symptoms of HCWs during reinfection with SARS-CoV-2 were milder, the high reinfection rate and short interval between infections indicate the need to enhance monitoring and protective measures for HCWs during the epidemic.

Prevalence and risk factors of anxiety and depression in patients with multi-drug/rifampicin-resistant tuberculosis.

Mental health disorders in patients with multi-drug or rifampicin-resistant tuberculosis (MDR/RR-TB) receive consistent attention. Anxiety and depression can manifest and may impact disease progression in patients with MDR/RR-TB. Given the heightened stressors resulting from the COVID-19 pandemic, this scenario is even more concerning. To evaluate the prevalence of and risk factors associated with anxiety and depression among patients with MDR/RR-TB in southern China. A facility-based cross-sectional study was undertaken at Guangzhou Chest Hospital in southern China, encompassing a cohort of 219 patients undergoing outpatient and inpatient treatment for MDR/RR-TB. Anxiety and depressive symptoms were assessed using the 7-Item Generalized Anxiety Disorder (GAD-7) scale and Patient Health Questionnaire-9 (PHQ-9). The ramifications of anxiety and depression were examined using univariate and multivariate logistic regression analyses, with odds ratios (ORs) and age- and sex-adjusted ORs (AORs) employed to quantify their influence. All data underwent statistical analysis using SPSS 25.0, with statistical significance established at P < 0.05. Two hundred and nineteen individuals with MDR/RR-TB were included in the study. The prevalence of anxiety and depression was 57.53% (n = 126) and 65.75% (n = 144), respectively, with 33.3% (n = 73) of the participants experiencing both conditions simultaneously. Multivariate logistic regression analysis revealed that an age of 20-40 years [anxiety AOR = 3.021, 95% confidence interval (CI): 1.240-7.360; depression AOR = 3.538, 95% CI: 1.219-10.268], disease stigma (anxiety AOR = 10.613, 95% CI: 2.966-37.975; depression AOR = 4.514, 95% CI: 2.051-10.108) and poor physical health (anxiety AOR = 7.636, 95% CI: 2.938-19.844; depression AOR = 6.190, 95% CI: 2.468-15.529) were significant risk factors for moderate levels of anxiety and depression. We found that individuals with MDR/RR-TB had an elevated risk of anxiety and depression. To decrease the likelihood of unfavorable treatment outcomes, it is imperative to carefully monitor the psychological wellbeing of patients with MDR/RR-TB and promptly address any detrimental psychiatric conditions.

Novice Chinese Bariatric Nurses' Perceptions of Their Role as Bariatric Case Managers: A Qualitative Study.

Bariatric case managers (BCM) are integral healthcare team members for patients undergoing bariatric surgery in China. As the demand for bariatric surgery increases in China, the number of BCMs has also risen. However, more is needed to know about the perceptions of novice bariatric nurses toward their role as case managers. This study aims to investigate the perceptions of novice Chinese bariatric nurses toward their roles during the early stages of their careers. This qualitative study employed semi-structured individual interviews with 15 novice bariatric nurses who received training as BCMs. The interviews were audio-recorded, transcribed line-by-line, and analyzed thematically. The study was conducted in a bariatric surgery center of a public tertiary hospital in Southern China. Three themes emerged from the data related to the perceptions of being a BCM: "negotiating the ambiguity of the BCM role," "establishing a core set of behaviors for the BCM role," and "identifying areas of competence to develop a BCM role framework." The novice bariatric nurses expressed both positive and negative feelings toward their role. They highlighted the need for further training to improve their qualifications and the importance of support from colleagues, and hospital management. The findings illuminate the role of the BCM in China. Future research should investigate effective and acceptable job descriptions and cooperation modes between BCMs, colleagues and hospital management. We recommend using these findings to develop training programs for novice BCMs and improve their capacity to provide quality care to patients undergoing bariatric surgery.

An analysis of neutrophil-to-lymphocyte ratios and monocyte-to-lymphocyte ratios with six-month prognosis after cerebral contusions.

Neutrophil-to-lymphocyte ratio (NLR) and monocyte-to-lymphocyte ratio (MLR) have been identified as potential prognostic markers in various conditions, including cancer, cardiovascular disease, and stroke. This study aims to investigate the dynamic changes of NLR and MLR following cerebral contusion and their associations with six-month outcomes. Retrospective data were collected from January 2016 to April 2020, including patients diagnosed with cerebral contusion and discharged from two teaching-oriented tertiary hospitals in Southern China. Patient demographics, clinical manifestations, laboratory test results (neutrophil, monocyte, and lymphocyte counts) obtained at admission, 24 hours, and one week after cerebral contusion, as well as outcomes, were analyzed. An unfavorable outcome was defined as a Glasgow Outcome Score (GOS) of 0-3 at six months. Logistic regression analysis was performed to identify independent predictors of prognosis, while receiver characteristic curve analysis was used to determine the optimal cutoff values for NLR and MLR. A total of 552 patients (mean age 47.40, SD 17.09) were included, with 73.19% being male. Higher NLR at one-week post-cerebral contusion (adjusted OR = 4.19, 95%CI, 1.16 - 15.16, P = 0.029) and higher MLR at admission and at 24h (5.80, 1.40 - 24.02, P = 0.015; 9.06, 1.45 - 56.54, P = 0.018, respectively) were significantly associated with a 6-month unfavorable prognosis after adjustment for other risk factors by multiple logistic regression. The NLR at admission and 24 hours, as well as the MLR at one week, were not significant predictors for a 6-month unfavorable prognosis. Based on receiver operating characteristic curve analysis, the optimal thresholds of NLR at 1 week and MLR at admission after cerebral contusion that best discriminated a unfavorable outcome at 6-month were 6.39 (81.60% sensitivity and 70.73% specificity) and 0.76 (55.47% sensitivity and 78.26% specificity), respectively. NLR measured one week after cerebral contusion and MLR measured at admission may serve as predictive markers for a 6-month unfavorable prognosis. These ratios hold potential as parameters for risk stratification in patients with cerebral contusion, complementing established biomarkers in diagnosis and treatment. However, further prospective studies with larger cohorts are needed to validate these findings.

Effect of banana intake on serum potassium level in patients undergoing maintenance hemodialysis: A randomized controlled trial

ObjectiveThis study aimed to assess the effect of banana intake during hemodialysis on serum potassium levels in maintenance hemodialysis (MHD) patients. MethodsThis study was a single-center, randomized controlled clinical trial conducted from September 15 to December 15, 2021, at a tertiary hospital in southern China. A total of 126 MHD patients were randomly assigned to either the intervention group (n = 64) or the control group (n = 62). Patients in the intervention group consumed approximately 250 g of bananas during hemodialysis, while those in the control group did not consume any food during hemodialysis. Demographic information and hemodialysis-related parameters were collected through case information collection before hemodialysis. Laboratory indicators (such as complete blood count, biochemical indicators, inflammation markers, liver function, kidney function, etc.) were evaluated by collecting pre-hemodialysis blood samples from patients. Serum potassium and blood glucose levels were measured at 2 h and 4 h of hemodialysis, as well as before the next hemodialysis session, and hemodialysis-related complications were recorded. The blood potassium and blood glucose indicators during hemodialysis were compared using repeated measures analysis. ResultsA total of 122 MHD patients completed the study (61 in each group). The results showed that there was no significant interaction between group and time on serum potassium levels. However, serum potassium levels in the intervention group were higher than those in the control group at 2 h (3.9 ± 0.5 mmol/L vs. 3.6 ± 0.3 mmol/L, P < 0.01) and 4 h (3.5 ± 0.4 mmol/L vs. 3.3 ± 0.3 mmol/L, P < 0.01) of hemodialysis. There was no interaction between group and time on blood glucose levels. The incidence of arrhythmias (8.2% vs. 29.5%, P = 0.003) and hypokalemia (52.5% vs. 80.3%, P = 0.002) during hemodialysis was significantly lower in the intervention group compared to the control group. ConclusionConsuming approximately 250 g of bananas at the start of hemodialysis does not lead to hyperkalemia. It can effectively reduce the incidence of hypokalemia and arrhythmias, and prevent a rapid decline in serum potassium levels during hemodialysis.

Bidirectional associations between dietary diversity and depressive symptoms in Chinese adult women: A retrospective cohort study

ObjectiveThis study aimed to examine the bidirectional associations between dietary diversity and clinical depressive symptoms in adult women, and influencing factors of clinical depressive symptoms. MethodsThis longitudinal study included a total of 22,385 participants, each of whom underwent at least two data collections. We used convenience sampling to recruit women from a health management center of a general hospital in southern China from April 2015 to December 2021. They completed an online self-reported health questionnaire, which included demographic characteristics, lifestyle information, the Dietary Diversity Scale (DDS), and the Patient Health Questionnaire-9. ResultsNew-onset depressive symptoms and low dietary diversity were observed in this study among 1285 and 3223 participants, respectively. Negative associations were observed between baseline low dietary diversity and new-onset depressive symptoms (P < 0.05) and between baseline depressive symptoms and low dietary diversity (P < 0.001). Cross-lagged panel analysis indicated that dietary diversity negatively and prospectively predicted depressive symptoms, but vice versa (P < 0.05). Strong evidence of a nonlinear association between DDS scores and incident depressive symptoms was found (P nonlinear < 0.05) regardless of whether the variables were adjusted. Besides, age, menarche age, physical activity, sleep duration, longer sedentary behavior and other lifestyle factors were influencing factors of depressive symptoms (P < 0.05). ConclusionsThe present study identified bidirectional associations between dietary diversity and depressive symptoms, and the associations were found to have a non-linear pattern. Adherence to dietary diversity and a healthy lifestyle could be effective non-pharmacological preventive measures to reduce the incidence of depressive symptoms.

A machine learning-based prediction model for postoperative delirium in cardiac valve surgery using electronic health records

BackgroundPrevious models for predicting delirium after cardiac surgery remained inadequate. This study aimed to develop and validate a machine learning-based prediction model for postoperative delirium (POD) in cardiac valve surgery patients.MethodsThe electronic medical information of the cardiac surgical intensive care unit (CSICU) was extracted from a tertiary and major referral hospital in southern China over 1 year, from June 2019 to June 2020. A total of 507 patients admitted to the CSICU after cardiac valve surgery were included in this study. Seven classical machine learning algorithms (Random Forest Classifier, Logistic Regression, Support Vector Machine Classifier, K-nearest Neighbors Classifier, Gaussian Naive Bayes, Gradient Boosting Decision Tree, and Perceptron.) were used to develop delirium prediction models under full (q = 31) and selected (q = 19) feature sets, respectively.ResultThe Random Forest classifier performs exceptionally well in both feature datasets, with an Area Under the Curve (AUC) of 0.92 for the full feature dataset and an AUC of 0.86 for the selected feature dataset. Additionally, it achieves a relatively lower Expected Calibration Error (ECE) and the highest Average Precision (AP), with an AP of 0.80 for the full feature dataset and an AP of 0.73 for the selected feature dataset. To further evaluate the best-performing Random Forest classifier, SHAP (Shapley Additive Explanations) was used, and the importance matrix plot, scatter plots, and summary plots were generated.ConclusionsWe established machine learning-based prediction models to predict POD in patients undergoing cardiac valve surgery. The random forest model has the best predictive performance in prediction and can help improve the prognosis of patients with POD.

Investigating the relationship between hepatitis B virus infection and postpartum depression in Chinese women: a retrospective cohort study.

Postpartum depression (PPD) is associated with several psychological and obstetric factors. Hepatitis B virus (HBV) infection has been linked with a high risk of depression, but little is known about the relationship between maternal HBV infection and PPD. We aimed to investigate the association between HBV infection and PPD. This retrospective cohort study included 3,808 mothers who gave birth in a hospital in southern China. Self-reported Edinburgh Postnatal Depression Scale (EPDS) was used to assess PPD. Multivariate logistic regression was used to determine whether maternal HBV infection was associated with PPD risk. Of the 3,808 participants, 11.9% of mothers had PPD at 6 weeks postpartum. Two hundred and seventy-eight (7.3%) and 3,530 (92.7%) were in the HBV and control groups, respectively. Women with HBV infection were more likely to test positive for PPD (14.7 vs.11.7%). The multivariate logistic regression analysis showed that HBV-infected women did not have a significantly higher incidence of PPD (OR = 1.23; 95% CI, 0.82-1.84) than those without HBV infection in the study cohort. Parity and postpartum hemorrhage were found to be associated with PPD. In addition, our study showed that e antigen positivity was not associated with PPD risk (OR = 0.56, 95% CI 0.19-1.63). To our knowledge, this is the first investigation of the relationship between maternal HBV infection and PPD. In a cohort of women without prior history or family history of mental illness, having HBV infection was not significantly associated with self-reporting of PPD compared to not having HBV infection.

Genomic insights into the phage-defense systems of Stenotrophomonas maltophilia clinical isolates

Stenotrophomonas maltophilia is a rapidly evolving multidrug-resistant opportunistic pathogen that can cause serious infections in immunocompromised patients. Although phage therapy is one of promising strategies for dealing with MDR bacteria, the main challenges of phage therapeutics include accumulation of phage resistant mutations and acquisition of the phage defense systems. To systematically evaluate the impact of (pro)phages in shaping genetic and evolutionary diversity of S. maltophilia, we collected 166 S. maltophilia isolates from three hospitals in southern China to analyze its pangenome, virulence factors, prophage regions, and anit-viral immune systems. Pangenome analysis indicated that there are 1328 saturated core genes and 26961 unsaturated accessory genes in the pangenome, suggesting existence of highly variable parts of S. maltophilia genome. The presence of genes in relation to T3SS and T6SS mechanisms suggests the great potential to secrete toxins by the S. maltophilia population, which is contrary to the conventional notion of low-virulence of S. maltophilia. Additionally, we characterized the pan-immune system maps of these clinical isolates against phage infections and revealed the co-harboring of CBASS and anti-CBASS in some strains, suggesting a never-ending arms race and the co-evolutionary dynamic between bacteria and phages. Furthermore, our study predicted 310 prophage regions in S. maltophilia with high genetic diversity. Six viral defense systems were found to be located at specific position of the S. maltophilia prophage genomes, indicating potential evolution of certain site/region similar to bacterial ‘defense islands’ in prophage. Our study provides novel insights into the S. maltophilia pangenome in relation to phage-defense mechanisms, which extends our understanding of bacterial-phage interactions and might guide the application of phage therapy in combating S. maltophilia infections.

Efficacy of vaginal natural orifice transluminal endoscopic sentinel lymph node biopsy for endometrial cancer: a prospective multicenter cohort study.

Natural orifice transluminal endoscopic surgery (NOTES) is performed increasingly often despite the lack of high-quality evidence confirming its safety, especially for malignant diseases. The aim of this prospective study is to verify that vaginal NOTES (vNOTES) can be performed safely and effectively in early endometrial cancer staging surgery. This prospective study was conducted in two tertiary hospitals in southern China from January 2021 to May 2022. A total of 120 patients with stage I endometrial cancer were included. vNOTES or multiport laparoscopic staging surgery was selected according to each patient's wishes. The primary outcome was the sentinel lymph node detection rate, analyzed by a noninferiority test. The secondary outcomes were perioperative outcomes. Among the 120 patients enrolled, 57 underwent vNOTES, and 63 underwent multiport laparoscopy. The patient-specific detection rates of sentinel lymph nodes were 94.73 and 96.82% in the vNOTES and laparoscopy groups, respectively. Additionally, the bilateral detection rates were 82.46 and 84.13%, and the side-specific detection rates were 88.60 and 90.48% in these two groups, respectively. All three detection rates in the vNOTES group were noninferior to those of laparoscopy group at a noninferiority cutoff of -15%. The median operation times of the vNOTES and laparoscopy groups were 132.35 and 138.73min ( P =0.362), and the median estimated blood loss were 75 and 50ml ( P =0.096), respectively. No intraoperative complications occurred in either group. The pain scores on the Numerical Rating Scale at both 12h and 24h after operation were significantly lower in the vNOTES group ( P <0.001) and the median postoperative hospital stay was significantly shorter in the vNOTES group ( P =0.001). This study illustrates the potential applicability of vNOTES in gynecological malignancy surgery by demonstrating its safety and effectiveness in endometrial cancer staging. However, its long-term survival outcomes require further exploration.

Dose-response associations of maternal age with pregnancy complications and multimorbidity among nulliparas and multiparas: A multicentric retrospective cohort study in southern China.

Advanced maternal age is becoming an increasingly common issue worldwide, presenting substantial health risks to pregnant women. However, dose-response associations of maternal age with a comprehensive range of pregnancy complications and their multimorbidity remain unclear. We conducted a retrospective cohort study using data from China's National Maternal Near Miss Surveillance System for 2017-2018, including 18 hospitals in southern China. We included 135 274 pregnant women aged 15-54 years with a singleton birth. We used multivariable logistic regression and restricted cubic spline to examine dose-response associations between maternal age and various pregnancy complications, as well as multimorbidity. We employed the Apriori algorithm to mine the association rules among pregnancy complications and identify frequent multimorbidity patterns. We found three distinct patterns of associations between maternal age and specific pregnancy complications. In relation to increasing maternal age, gestational diabetes mellitus, preeclampsia, and gestational hypertension showed nonlinear increasing trends for both nulliparas and multiparas, as did multimorbidity in nulliparas. Conversely, we observed linear increasing trends for placental previa in both nulliparas and multiparas, placental abruption in nulliparas, and multimorbidity in multiparas. Infection and severe anaemia had an approximate J-shaped curve among nulliparas, while postpartum haemorrhage exhibited a similar curve in both nulliparas and multiparas. Advanced maternal age was linked to an elevated risk of multimorbidity during pregnancy or postpartum period, exhibiting more complicated patterns. The most common multimorbidity patterns in this age group were "preeclampsia + gestational diabetes mellitus", "gestational hypertension + gestational diabetes mellitus", "infection + gestational diabetes mellitus", and "placental previa + gestational diabetes mellitus". Maternal age was associated with pregnancy complications and multimorbidity in three broad dose-response manners, including approximate J-shaped curves, as well as nonlinear and linear increasing trends, depending on the specific outcome and parity, which may suggest different underlying biological mechanisms. Women with advanced maternal age had a higher risk and more complicated patterns of multimorbidity during pregnancy or postpartum, suggesting that this group should be targeted for more intensive health care.

Analysis of distribution and antibiotic resistance of Gram-positive bacteria isolated from a tertiary-care hospital in southern China: an 8-year retrospective study.

Due to the severe drug resistance situation of Gram-negative bacteria, especially Gram-negative enterobacter, relatively little attention has been paid to the changes in Gram-positive bacteria species and drug resistance. Therefore, this study analyzed the prevalence and drug resistance of Gram-positive bacteria in a general tertiary-care hospital from 2014 to 2021, in order to discover the changes in Gram-positive bacteria distribution and drug resistance that cannot be easily identified, inform clinicians in their respective regions when selecting antimicrobial agents, and to provide the basis for the diagnosis of Gram-positive bacterial infection, and for the comprehensive and multi-pronged prevention and control of drug-resistant bacteria. A retrospective study was conducted on Gram-positive bacteria isolated from patients presented to a general tertiary-care hospital from January 2014 to December 2021. A total of 15,217 Gram-positive strains were analyzed. During the 8-year period, the total number and the species of Gram-positive bacteria isolated from clinic increased continuously. The seven most common species were Streptococcus pneumoniae (21.2%), Staphylococcus aureus (15.9%), Enterococcus faecium (20.6%), Enterococcus faecalis (14.0%), and Staphylococcus epidermidis (7.8%), Staphylococcus haemolyticus (4.8%), Streptococcus agalactiae (3.6%). The isolation rates of Staphylococcus aureus and Streptococcus agalactiae increased, and the isolation rate of Enterococcus faecium decreased. The resistance rates of Staphylococcus aureus to erythromycin, clindamycin, tetracycline, rifampicin and furantoin decreased obviously. The resistance rates of Streptococcus pneumoniae to cefepime (non-meningitis) and ceftriaxone (meningitis) decreased significantly. The resistance rates of Enterococcus faecium to penicillin, ampicillin, erythromycin, levofloxacin, ciprofloxacin and furantoin rose rapidly from 50.3, 47.6, 71.5, 44.9, 52.3, and 37.5% in 2014 to 93.1, 91.6, 84.9, 86.8, 86.8, and 60.0% in 2021, respectively. The total number and the species of Gram-positive bacteria isolated during the 8-year period increased continuously. Streptococcus pneumoniae and Staphylococcus aureus are the main causes of positive bacterial infections in this hospital. The resistance rates of Enterococcus faecium to a variety of commonly used antibiotics increased significantly. Therefore, it is very important to monitor the distribution of bacteria and their resistance to antibiotics to timely evaluate and identify changes in drug resistance that are not easily detected.

Influence of metabolic syndrome and lifestyle factors on thyroid nodules in Chinese adult men: a cross-sectional study.

Given the high prevalence of thyroid nodules and the potential for malignancy, it is imperative to understand the various factors that contribute to their development. This study aimed to explore the relationship between metabolic syndrome, lifestyle, and thyroid nodules in adult men in southern China. This study enrolled a total of 183,990 subjects at a medical examination center in a general hospital in southern China between January 1, 2015, and December 31, 2020. Multivariate logistic regression analysis was utilized to evaluate the relationship between metabolic syndrome, lifestyle factors, and thyroid nodules. Furthermore, structural equation modeling elucidated the intricate relationships among these variables. The prevalence of thyroid nodules among Chinese adult males was 14.9%. Several factors were identified as risk factors for thyroid nodules, including advanced age, irregular meal time, smoking or quitting smoking, quitting drinking, heavy manual labor, hypertension, diabetes, dyslipidemia and centripetal obesity, and those belonging to ethnic minorities and drinking alcohol were found to be protective factors against thyroid nodules. Structural equation modeling highlighted metabolic syndrome's mediating role amidst lifestyle influences on thyroid nodules. The prevalence of thyroid nodules in Chinese adult males is relatively moderate to low. The factors identified in this study can help clinicians identify high-risk patients and develop targeted screening strategies for the timely detection of thyroid nodules. However, further mechanistic research and longitudinal studies are necessary to explore the underlying causes and establish causal relationships.

Perceptions and experiences of exercise among pregnant women

IntroductionThough exercise during pregnancy can yield important maternal benefits, most pregnant women in China do less aerobic exercise than is currently recommended. This qualitative study aimed to explore the perceptions and experiences of physical exercise among pregnant women and to identify perceived barriers to and facilitators of exercise participation. MethodsPurposive sampling was used to recruit 40 pregnant women attending prenatal visits at an obstetrics outpatient department of a tertiary general hospital in Southern China. Individual semi-structured telephone interviews were conducted with the verbatim transcripts analyzed through content analysis. ResultsThree main themes emerged from the data: perceptions and patterns of exercise; concerns and hesitations about participating in exercise; and determinants of adoption and maintenance of exercise participation. Though pregnant women recognised their need for physical exercise instruction, their demands remained unmet due to a combination of factors such as lack of knowledge, confidence, and support, and concerns about safety. DiscussionThe findings of this study suggest that the provision of tailored exercise programs for pregnant women, which include education, reassurance, motivational strategies, and lay and professional support, may help improve knowledge, allay concerns, boost confidence, and bolster support when doing physical exercise.

Prevalence of risk factors associated with rupture of abdominal aortic aneurysm (AAA): a single center retrospective study.

Abdominal aortic aneurysm (AAA) is a severe cardiovascular disease. The mortality rate for an AAA rupture is very high. Understanding the risk factors for AAA rupture would help AAA management, but little is known about these risk factors in the Chinese population. This retrospective study included patients that were diagnosed with AAA during the last 5 years in a large national hospital in southern China. AAA patients were divided into a rupture and non-rupture group. Clinical data were extracted from the hospital medical record system. Clinical features were compared between the rupture and non-rupture groups. The associations between potential risk factors and rupture risk were evaluated using a multivariate logistic regression analysis. A total of 337 AAA patients were included for analysis in the present study. AAA diameter was significantly larger, and high-sensitivity C-reactive protein (hs-CRP) and serum creatinine levels were both significantly higher in AAA rupture patients. High-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and total cholesterol (TC) levels were significantly lower in AAA rupture patients. After adjustment, the multivariate logistic analysis found that AAA diameter and hs-CRP were independently positively associated with AAA rupture, and HDL-C level was adversely associated with AAA rupture. Our data suggests that larger AAA diameter and higher hs-CRP level are associated with a higher risk of AAA rupture, and higher HDL-C level is associated with a lower risk of AAA rupture. The results of this study may be helpful for the management of AAA patients in southern China.

Preferences of pregnant individuals to undergo labor after one cesarean in southern China.

Labor after cesarean (LAC) remains an optional delivery method among healthy pregnant individuals. Exploring women's attitudes, preferences, reasons for previous cesarean delivery, and the incentives underlying pregnant individuals' preferences could help us understand their choice of delivery mode. In this study we evaluated the preferences and attitudes of eligible pregnant women regarding participation in a LAC in Foshan, China. A cross-sectional survey was conducted among 438 pregnant individuals with one prior cesarean delivery (CD) who attended their antenatal examination at a tertiary hospital in southern China, between November 1, 2018, and October 31, 2019. Information on demographic characteristics, obstetric data, preferences for LAC, and incentives for LAC were analyzed. Overall, 85.4% (374/438) of women preferred LAC if they did not have contraindications before delivery, whereas 12.3% (54/438) refused and 2.3% (10/438) were unsure. Participants reported that the most important factors affecting their willingness to undergo LAC were safety indicators (i.e., "ability of hospitals to perform emergency cesarean delivery" [score of 9.28 ± 1.86]), followed by accessibility indicators (i.e., "priority bed arrangements" [score of 9.17 ± 1.84]). Logistic regression analysis indicated that neonatal wellbeing with the prior CD was an independent influencing factor (OR = 2.235 [95%CI: 1.115-4.845], p = 0.024) affecting willingness to access LAC in the subsequent pregnancy. We found a high preference for LAC among pregnant individuals without contraindications before delivery in southern China. Healthcare providers need to ensure access to LAC and increase pregnant individuals' LAC willingness through high-quality shared decsision-making in alignment with patient preferences.

The Epidemiology and Clinical Characteristics of Fungemia in a Tertiary Hospital in Southern China: A 6-Year Retrospective Study.

Knowledge of the epidemiology and clinical characteristics of fungemia in southern China is limited. We conducted a six-year retrospective descriptive study to analyze the epidemiological and clinical characteristics of fungemia at the largest tertiary hospital in Guangxi, southern China. Data were obtained from the laboratory registry of patients with fungemia between January 2014 and December 2019. Demographic characteristics, underlying medical conditions, and outcomes for each case were analyzed. A total of 455 patients with fungemia were identified. Unexpectedly, Talaromyces marneffei (T. marneffei) was the most frequently isolated agent causing fungemia in the region (149/475, 31.4%), and Candida albicans (C. albicans) was the most commonly isolated Candida spp. (100/475, 21.1%). We identified that more than 70% of talaromycosis fungemia developed in AIDS patients, whereas candidemia was most commonly associated with a history of recent surgery. Notably, the total mortality rate of fungemia and the mortality rate in patients with T. marneffei and Cryptococcus neoformans (C. neoformans) fungemia were significantly higher in HIV-uninfected patients than in HIV-infected patients. In conclusion, the clinical pattern of fungemia in Guangxi is different from that in previous studies. Our study may provide new guidance for the early diagnosis and prompt treatment of fungemia in similar geographic regions.

Stigma and its correlates among patients with Crohn’s disease: A cross-sectional study in China

ObjectivesCrohn’s disease is an incurable disease characterized by unpredictable intestinal symptoms, which unavoidably affect patients’ lives and contribute to feelings of stigma. This study aimed to explore the status and its correlates of stigma among patients with Crohn’s disease. MethodsUsing a convenience sampling, 146 hospitalized patients with Crohn’s disease were recruited in a tertiary hospital in Southern China from October 2020 to March 2021. The participants were assessed by demographic and disease-related questionnaires, the Social Impact Scale (SIS), Inflammatory Bowel Disease-Self-Efficacy Scale (IBD-SES), and Social Support Rating Scale (SSRS). Multivariate linear regression analysis was conducted to explore the influencing factors of stigma among patients with Crohn’s disease. ResultsThe mean SIS score was 58.14 ± 10.74, representing a moderate effect of stigma, and 85.6% (125/146) of the patients experienced moderate to high levels of stigma. The multiple linear regression analysis showed that perceived public awareness of the disease, family income, age, and self-efficacy were the main influencing factors of stigma, which could explain 52% of the total variation of stigma among patients with Crohn’s disease. ConclusionStigma among patients with Crohn’s disease is influenced by perceived public awareness of the disease, family income, age, and self-efficacy. Interventions aimed at improving self-efficacy and public awareness should be considered to alleviate the level of stigma, especially for those aged 40 years or older or low-income patients.

Characteristics of patients with incidental eosinophilia admitted to a tertiary hospital in southern China

BackgroundThe characteristics of patients with eosinophilia are heterogeneous and the outcomes can vary from asymptomatic to severe. ObjectiveTo describe the feature of patients with eosinophilia in a single center. DesignBased on the electronic medical records from Yangjiang People's Hospital in China, the inpatients admitted between June 2018 and February 2021 with measured blood eosinophil counts were evaluated. MethodsEosinophilia was defined as a peripheral blood eosinophil count of ≥0.5 × 109/L. Differences were compared by eosinophilia severity. The medical records of patients with moderate to severe eosinophilia were reviewed and summarized in terms of examination, diagnoses and management. And these patients were matched with patients without incidental eosinophilia by propensity score and the differences were compared. ResultsA total of 7,835 patients with eosinophilia were identified out of 131,566 total inpatients. All types of eosinophilia were most common in males (8.2%; 5,351/65,615), and in patients aged 0–6 years (11.6%; 1,760/15,204), and in the pediatric (10.8%; 1,764/16,336) department, followed by dermatology (10.6%; 123/1,162), Oncology (7.5%; 394/5,239) and Intensive care unit (ICU) (7.4%; 119/1,608). Patients with moderate to severe eosinophilia were more likely to admit to ICU (moderate: 1.3%; severe: 0.50%). In patients with moderate to severe eosinophilia, only 205/621 (33%) had eosinophilia mentioned in their records, and only 63/621 (10.1%) underwent investigations for eosinophilia. The majority of patients with moderate to severe eosinophilia (372/621, 59.9%) had an infectious disease, and little examination (7.4%; 46/621) was taken to identify the cause of eosinophilia, and only 39/621 (6.3%) of patients had a discrete cause of eosinophilia identified. Patients with moderate to severe eosinophilia (24.3%; 151/621) exhibited certain chance to have organ dysfunction. ConclusionIncidental eosinophilia in inpatients was frequently neglected and less investigated. Multidisciplinary consultation may improve outcomes of inpatients with moderate to severe eosinophilia.
