Baduanjin exercise intervention trial: research protocol of a randomised controlled trial for frail kidney transplant recipients.

INTRODUCTION: Frailty is one of the most common comorbidities in kidney transplant recipients (KTRs). Physical, psychological and social frailty could be improved by exercise intervention. Baduanjin, also known as Eight-section Brocades, is a type of traditional Chinese medicine exercise characterised by the interplay between physical postures and movements, breathing and mind. It can help frail patients strengthen their upper and lower body muscles, improve their mood, quality of life and frailty. However, the effectiveness of Baduanjin on frail KTRs remains unknown. Therefore, we will conduct a randomised controlled trial (RCT) to evaluate the effectiveness of Baduanjin on frail KTRs. METHODS AND ANALYSIS: This protocol describes an assessor and analyst blinded, parallel RCT for frail KTRs comparing Baduanjin group (n=72) with care-as-usual group (n=72). The primary outcomes are frailty assessed by Frailty Phenotype scale and Tilburg Frailty Indicator scale, and muscle strength assessed by a grip strength metre. The secondary outcomes are quality of life assessed by Medical Outcomes Study 36-Item Short-Form Health Survey (MOS SF-36) and depression assessed by the Hospital Anxiety and Depression Scale. All these data will be collected at the baseline, after 3, 6, 9 and 12 months, respectively. Two-way mixed analysis of variance (ANOVA) will be used to test the effectiveness of Baduanjin exercise. Qualitative interviews with participants in the intervention group will also be performed after 6 months. Themes will be extracted from interview transcripts using NVivo software. ETHICS AND DISSEMINATION: The Ethics Committees of Beijing University of Chinese Medicine (2022BZYLL1018) and China-Japan Friendship Hospital (2022-KY-250) had approved the study. The organ donors were all from China-Japan Friendship Hospital. They provided informed consent and they were not executed prisoners. We have provided BMJ Open with documentation from the hospital that indicates that the organs will be harvested ethically. The findings of this study will be disseminated through peer-reviewed journals, international conferences, media reports and briefings. TRIAL REGISTRATION NUMBER: ChiCTR2100041730.

Trajectories of depressive symptoms in young and middle-aged men who have sex with men with new HIV-diagnosis: a 1-year prospective cohort study in Beijing, China.

Introduction: Due to the sexual orientation and HIV diagnosis, young and middle-aged men who have sex with men (MSM) with new HIV-diagnosis may experience more depressive syndromes and face greater psychological stress. The study explored trajectories of depressive symptoms of young and middle-aged MSM within 1 year after new HIV-diagnosis and analyze the related factors. Methods: From January 2021 to March 2021, 372 young and middle-aged MSM who were newly diagnosed as HIV-infection were recruited in two hospitals in Beijing. Self-rating Depression Scale was used to measure the participants' depressive symptom in 1st month, 3rd month, 6th month, 9th month and 12th month after HIV diagnosis. The latent class growth model was used to identify trajectories of the participants' depressive symptoms. Multinomial logistic regression was used to analyse factors related with the trajectories. Results: Three hundred and twenty-eight young and middle-aged MSM with new HIV-diagnosis completed the research. Depressive symptom in 328 young and middle-aged MSM was divided into three latent categories: non-depression group (56.4%), chronic-mild depression group (28.1%), and persistent moderate-severe depression group (15.5%). The participants assessed as non-depression (non-depression group) or mild depression (chronic-mild depression group) at the baseline were in a non-depression state or had a downward trend within one-year, and the participants assessed as moderate and severe depression (persistent moderate-severe depression group) at the time of diagnosis were in a depression state continuously within 1-year. Multinomial logistic regression analysis showed that, compared with the non-depression group, monthly income of 5,000 ~ 10,000 RMB (equal to 690 ~ 1,380 USD) was the risk factor for the chronic-mild depression group, and self-rating status being fair/good and self-disclosure of HIV infection were protective factors for the persistent moderate-severe depression group while HIV-related symptoms was the risk factor. Conclusion: Depressive symptoms in young and middle-aged MSM is divided into three latent categories. Extra care must be given to young and middle-aged MSM assessed as moderate or severe depression at the time of HIV-diagnosis, especially to those who had poor self-rating health status, did not tell others about their HIV-infection and experienced HIV-related symptoms.

Development of a clinical automatic calculation of hypoglycemia during hemodialysis risk in patients with diabetic nephropathy.

BACKGROUND: Hypoglycemia is one of the most common complications in patients with DN during hemodialysis. The purpose of the study is to construct a clinical automatic calculation to predict risk of hypoglycemia during hemodialysis for patients with diabetic nephropathy. METHODS: In this cross-sectional study, patients provided information for the questionnaire and received blood glucose tests during hemodialysis. The data were analyzed with logistic regression and then an automated calculator for risk prediction was constructed based on the results. From May to November 2022, 207 hemodialysis patients with diabetes nephropathy were recruited. Patients were recruited at blood purifying facilities at two hospitals in Beijing and Inner Mongolia province, China. Hypoglycemia is defined according to the standards of medical care in diabetes issued by ADA (2021). The blood glucose meter was used uniformly for blood glucose tests 15 minutes before the end of hemodialysis or when the patient did not feel well during hemodialysis. RESULTS: The incidence of hypoglycemia during hemodialysis was 50.2% (104/207). The risk prediction model included 6 predictors, and was constructed as follows: Logit (P) = 1.505×hemodialysis duration 8~15 years (OR = 4.506, 3 points) + 1.616×hemodialysis duration 16~21 years (OR = 5.032, 3 points) + 1.504×having hypotension during last hemodialysis (OR = 4.501, 3 points) + 0.788×having hyperglycemia during the latest hemodialysis night (OR = 2.199, 2 points) + 0.91×disturbance of potassium metabolism (OR = 2.484, 2 points) + 2.636×serum albumin<35 g/L (OR = 13.963, 5 points)-4.314. The AUC of the prediction model was 0.866, with Matthews correlation coefficient (MCC) of 0.633, and Hosmer-Lemeshow χ2 of 4.447(P = 0.815). The automatic calculation has a total of 18 points and four risk levels. CONCLUSIONS: The incidence of hypoglycemia during hemodialysis is high in patients with DN. The risk prediction model in this study had a good prediction outcome. The hypoglycemia prediction automatic calculation that was developed using this model can be used to predict the risk of hypoglycemia in DN patients during hemodialysis and also help identify those with a high risk of hypoglycemia during hemodialysis.

Diabetes self-management and its related factors among Chinese young adults with type 2 diabetes mellitus.

AIM: To explore the status quo of self-management among young adults with type 2 diabetes mellitus (T2DM) and the determinants of self-management under the guidance of social cognitive theory. DESIGN: A cross-sectional study. METHODS: In total, 227 young adults (18-44 years old) with T2DM at two hospitals in Beijing completed the questionnaires. The Summary of Diabetes Self-care Activities (SDSCA) was used, along with additional questionnaires about diabetes self-efficacy, attitude, diabetes distress, diabetes knowledge, coping styles and social support. Univariate analysis and multiple linear regression were used to explore the related factors of self-management among the young patients. RESULTS: The scores for the SDSCA in diet, exercise, blood-glucose testing, foot care and medication taking were (4.16 ± 1.51), (3.46 ± 2.50), (2.28 ± 2.24), (1.08 ± 1.84) and (6.09 ± 1.88), respectively. Stepwise multiple linear regression showed that fasting blood-glucose value was significantly associated with self-management behaviours of diet, exercise, blood-glucose testing and medication taking. Self-efficacy was significantly associated with self-management behaviours of diet, exercise and foot care. Diabetes distress, diabetes-related social activity, confrontation, education, duration of T2DM, treatment modalities and diabetes knowledge were associated with the one or two dimensions of SDSCA in the young adults with T2DM.

Development and validation of the Chinese version of the self-management support scale for kidney transplant recipients.

BACKGROUND: Providing self-management support to kidney transplant recipients is essential. However, a scale to identify the self-management support they have received is lacking. The purpose of this study is to develop a Self-management Support Scale for Kidney Transplant Recipients (SMSSKTR) and test its psychometric properties. METHODS: This is an instrument development and validation study, which has a three-stage cross-sectional design. In Stage 1, a preliminary item pool was formed using a literature review, semi-structured interviews, and the Delphi method. In Stage 2, six experts were invited to assess content validity. A convenience sample of 313 participants was used to explore the factor structure by using exploratory factor analysis. The test-retest reliability was assessed using the intra-class correlation coefficient (ICC). In Stage 3, two hundred and sixty-five participants were recruited to validate the factor structure by using confirmatory factor analysis. Convergent validity was examined using Spearman's correlation coefficient. Cronbach's alpha coefficient and corrected item-total correlation coefficient were used to test the reliability of the entire scale and its dimensions. The study was reported according to the STARD and GRRAS checklists. RESULTS: An initial 40-item scale was developed in Stage 1. In Stage 2, three factors with 22 items emerged from the exploratory factor analysis: instrumental support, psychosocial support, and relational support. The content validity index of the scale was 0.97. The intra-class correlation coefficient for the entire scale and the subscales were 0.915, 0.771, 0.896, and 0.832, respectively. In Stage 3, the confirmatory factor analysis indicated that the three-factor model had a good fit. The score of the scale was positively associated with that of the Self-Management Scale of Renal Transplant Recipients (r = 0.532). Cronbach's alpha was 0.959 for the entire scale and 0.956-0.958 for the three subscales. The corrected item-total correlation coefficient ranged from 0.62 to 0.82. CONCLUSION: The 22-item SMSSKTR has sufficient psychometric properties to assess the self-management support they have received, which has not been measured before.

Study on the effects of different postprandial positions on blood pressure and heart rate in older adults with primary hypertension and postprandial hypotension.

This randomized controlled trial explored the effects of a supine position or a semi-fowler position on postprandial blood pressure (BP) of older adults with primary hypertension and postprandial hypotension (PPH). Ninety-six participants were divided into the supine group, the semi-fowler group, and the control group with block-randomization. After a meal, the patients were placed in a supine position, a 45° semi-fowler position, or allowed daily activities, respectively. BP, heart rate and PPH symptoms were measured 5 times in 120 minutes after the meal. Repeated measurement analysis showed no statistical difference in BP, heart rate and PPH symptom scores among the three groups. BP in all groups decreased rapidly at the 30-minute point, and then moved steadily downward. Taking a supine position or semi-fowler position after meals had no effect on postprandial BP and heart rate after meals in older adults with hypertension and PPH.

Sub-Exome Target Sequencing in a Family With Syndactyly Type IV Due to a Novel Partial Duplication of the LMBR1 Gene: First Case Report in Fujian Province of China.

Syndactyly is one of the most frequent hereditary limb malformations with clinical and genetical complexity. Autosomal dominant syndactyly type IV (SD4) is a rare form of syndactyly, caused by heterozygous mutations in a sonic hedgehog (SHH) regulatory element (ZRS) which resides in intron 5 of the LMBR1 gene on chromosome 7q36.3. SD4 is characterized by complete cutaneous syndactyly of the fingers, accompanied by cup-shaped hands due to flexion of the fingers and polydactyly. Here, for the first time, we reported a large Chinese family from Fujian province, manifesting cup-shaped hands consistent with SD4 and intrafamilial heterogeneity in clinical phenotype of tibial and fibulal shortening, triphalangeal thumb-polysyndactyly syndrome (TPTPS). We identified a novel duplication of ∼222 kb covering exons 2-17 of the LMBR1 gene in this family by sub-exome target sequencing. This case expands our new clinical understanding of SD4 phenotype and again confirms the feasibility to detect copy number variation by sub-exome target sequencing.

A culturally sensitive nurse-led structured education programme in patients with type 2 diabetes.

AIM: To assess the feasibility, acceptability, and preliminary efficacy of a culturally sensitive nurse-led structured education programme for patients with type 2 diabetes. BACKGROUND: A nurse-led satisfactory diabetes education programme might be feasible. The structured education programme is considered a potential model that helps patients manage diabetes. DESIGN: A mixed-method design. METHODS: A convenience sample of 44 participants received the programme. Feasibility was assessed using the recruitment rate and the retention rate. Acceptability was assessed by interviews to obtain the perception and experience of participants. Also, preliminary efficacy on diabetes knowledge, self-efficacy, self-management behaviours, and clinical outcomes was assessed. Finally, data were collected from April to December 2015. RESULTS: The recruitment rate and the retention rate were acceptable. Participants thought that the programme contributed to their positive changes. They enjoyed and accepted the programme, and they wanted to gain the ongoing support. Significant improvements in diabetes knowledge, self-efficacy, self-management behaviours, A1C , fasting blood glucose, low-density lipoprotein cholesterol, weight, body mass index, and waist circumference were reported in 12-week follow-up. CONCLUSIONS: This programme is feasible and acceptable, and its preliminary efficacy is promising. Ongoing support, a control group, and long-term follow-up are required in future studies to assess its effectiveness.

Novel loss-of-function mutation in BRCA2 gene identified in a Chinese female with a family history of ovarian cancer: A case report.

Inherited loss-of-function mutations in the tumor suppressor BRCA2 gene are associated with a high risk of ovarian cancer in the Chinese population. The current case report discusses a novel heterozygous insertion in BRCA2 gene, c.3195_3196insA, in a 54-year-old Chinese female with hereditary ovarian cancer. This frameshift mutation generates a premature stop codon at amino acid 1,076, which leads to a truncated BRCA2 protein instead of a wild-type BRCA2 protein with 3,418 amino acids. According to the Breast Cancer Information Core database, this mutation has not been previously reported. However, germline mutations of BRCA2 are a more prevalent cause of ovarian cancer in Chinese females compared with females in Western populations. The present study expands the mutational spectra of BRCA2 that is associated with ovarian cancer.

A Novel MLH1 Initiation Codon Mutation (c.3G>T) in a Large Chinese Lynch Syndrome Family with Different Onset Age and mRNA Expression Level.

Lynch syndrome is a genetically and clinically heterogeneous disorder; it is caused by a germline mutation in DNA mismatch repair (MMR) genes. Individuals with a heterozygous mutation in MLH1 have an increased risk for developing colorectal cancer. Here we described a 5-generation Chinese Lynch syndrome family with different severity and onset age. A novel heterozygous germline mutation (c.3G>T, p.Met1Ile) in MLH1 gene was discovered by next generation sequencing. Our study also revealed by qPCR that the MLH1 mRNA expression in peripheral blood of patients in this family was remarkably lower than that of the unaffected carriers and non-carriers. The research results indicated that the mRNA expression level may provide predictive suggestions of treatment and management for carriers with the initiation codon mutation of MLH1 in this family. Further studies are undertaken in this family as well as other families with Lynch syndrome to interrogate the exact reasons affecting the MLH1 mRNA expression level and whether mRNA expression in peripheral blood could be a significant factor for early diagnosis and surveillance of Lynch syndrome.

Identification of a novel breast cancer-causing mutation in the BRCA1 gene by targeted next generation sequencing: A case report.

Hereditary breast cancer is an autosomal dominant syndrome caused by germ-line mutations in the human breast cancer genes, BRCA1 and BRCA2. Mutations in either BRCA1 or BRCA2 are the major causes of familial and early-onset breast cancer. The present study investigated a 33-year-old Chinese female patient with breast cancer using targeted next generation sequencing. A novel heterozygous deletion-insertion was also identified in the BRCA1 gene, c.311_312delinsAGGTTTGCA, which causes the formation of a truncated BRCA1 protein of 109 amino acids instead of a wild-type BRCA1 protein of 1,863 amino acids. These results could potentially expand the mutational spectra of BRCA1-associated breast cancer. In addition, these findings may be valuable for the mutation-based screening and genetic diagnosis of breast cancer.

Effects of depression, diabetes distress, diabetes self-efficacy, and diabetes self-management on glycemic control among Chinese population with type 2 diabetes mellitus.

AIM: To examine the direct and indirect effects of depression, diabetes distress, diabetes self-efficacy and diabetes self-management on glycemic control among a group of T2DM patients in China. METHOD: A convenience sample of 254 participants were selected from three outpatient departments in Beijing, China. They were surveyed using a self-administered questionnaire. Diabetes-related information was retrieved from their medical records. Descriptive statistics, independent student t tests, Chi-square tests, correlation analyses and Generalized Structural Equation Modeling were used. RESULTS: Only 91 (35.82%) participants achieved optimal glycemic control of HbA1c<7.0% (53mmol/mol). Only diabetes self-management had a direct effect on glycemic control (OR=0.95, P<0.001). Depression and diabetes distress had only indirect effects on glycemic control through both diabetes self-efficacy and diabetes self-management. Diabetes self-efficacy only had an indirect effect on glycemic control through diabetes self-management. CONCLUSIONS: Glycemic control among Chinese population with T2DM was suboptimal. Future interventions should focus on decreasing depressive symptoms and diabetes distress levels, and, therefore, improve diabetes self-efficacy and self-management practices and, ultimately, reach the optimal goal of glycemic control.

Making Patient Risk Visible: Implementation of a Nursing Document Information System to Improve Patient Safety.

OBJECTIVES: The aims of this study were to develop a nursing information system (NIS), enhance the visibility of patient risk, and identify challenges and facilitators to adoption of the NIS risk assessment system for nurse leaders. METHODS: This article describes the function of a nursing risk assessment information system, and the results of a survey on the risk assessment system. RESULTS: The results suggested that quality of information processing in nursing significantly improved patient safety. Nurses surveyed demonstrated a high degree of satisfaction, with saving time and improving safety. CONCLUSIONS: The nursing document information system described was introduced to improve patient safety and decrease risk. The application of the system has greatly enhanced the efficiency of nursing work, and guides the nurses to make an accurate, comprehensive and objective assessment of patient information, contributing significantly to further improvement in care standards and care decisions.

Across-sectional study on anxiety and stress in pregnant women with chronic HBV infection in the People's Republic of China.

PURPOSE: To investigate the anxiety and pregnancy-associated stress of pregnant women with chronic hepatitis B virus (HBV) infection in the People's Republic of China and analyze the relationship between anxiety and pregnancy-associated stress in the hope of finding ways to reduce the stress or improve the coping skills for these mothers-to-be during pregnancy. METHODS: A cross-sectional study was conducted. One hundred and sixty chronic HBV-infected pregnant women (HBV group) and 160 healthy pregnant women (control group) selected from three Peking University-affiliated hospitals participated in the study, and completed the State-Trait Anxiety Inventory (STAI) and Pregnancy Stress Rating Scale (PSRS) survey. RESULTS: The mean scores of STAI and PSRS for the HBV group were higher than for the control group. Factor 2 of PSRS (stress caused by worrying about mother and child's health and safety) was the highest, and was significantly higher in the HBV group than in the control group. Correlation analysis showed STAI scores were significantly correlated with economic status and diagnosis, as well as the total score, factor 1 (stress about identifying with the role of mother), and factor 2 of PSRS, but not significantly correlated with factor 3 of PSRS (stress caused by the changes of body shape and physical activity). CONCLUSION: Pregnant women with chronic HBV infection experienced higher levels of anxiety and stress than healthy pregnant women. Their major stress came from concerns for the health and safety of the mother and the child.

Clinical analysis of 10 AIDS patients with malignant lymphoma.

OBJECTIVE: This work summarizes the clinical features and treatment of 10 AIDS patients with malignant lymphoma. METHODS: A total of 10 AIDS patients with malignant lymphoma seen in Beijing Ditan Hospital since 2009 were enrolled. Clinical manifestations, pathological examinations, immunity levels, Epstein-Barr virus antibody examinations, complications, treatments, and outcomes were retrospectively analyzed. RESULTS: The main clinical manifestations of these patients included intermittent fever in 2 cases, neck masses and fever in 3 cases, auxiliary lymph node enlargement in 2 cases, and abdominal pain and bloating with fever in 3 cases. Up to 7 patients were pathologically diagnosed with diffuse large B cell lymphoma (DLBCL), and 3 patients were pathologically diagnosed with Burkitt's lymphoma. Up to 8 patients had CD4 cell counts below 200/µL, and 2 patients had a level of more than 200/µL. Up to 7 patients were negative for EBV-IgM antibodies and 3 patients were not examined. Six patients underwent different chemotherapy and their prognoses were different. One patient with Burkitt's lymphoma alternatively took CODOXM and IVAC for 3 turns after VP chemotherapy; 1 patient with liver metastasis took R-CHOP 5 times, then changed therapy regimen to R-MINE and MINE. One patient with adrenal DLBCL took CHOP 6 times. Three patients with DLBCL took CHOP 1 or 2 times. Four patients gave up treatment. Various infections and side effects occurred, including bone marrow suppression, gastrointestinal bleeding, and renal dysfunction during chemotherapy. Six patients took HAART, and 4 did not. Six patients died, whereas 3 patients got improved; and 1 patient was discharged. CONCLUSIONS: AIDS patients with malignant lymphoma had various clinical manifestations, were immunocompromised, and had multiple metastases when they were admitted; they were already in the interim or late stage of lymphoma. Chemotherapy was not effective, and additional complications occurred. HAART failed to improve patient prognosis, and the overall prognosis was poor.

Women and HIV/AIDS in China: gender and vulnerability.

A comprehensive literature review was conducted to determine if there was a research gap between women's vulnerability to HIV and research addressing that vulnerability in China. Türmen's article Gender and HIV/AIDS served as a framework for examining the eight determinants placing women and adolescent girls at greater risk of HIV infection than men. Eighty-eight research reports were retrieved and categorized by general characteristics and the eight determinants. Women were found to be more vulnerable than men to HIV infection in China and worldwide. While researchers reported a considerable amount of research regarding women's HIV/AIDS-related issues in China, there is insufficient attention to some risk determinants. Investigators are encouraged to take advantage of political commitment and policy changes in China to conduct more research focusing on female vulnerability and to address the effects of violence, laws, stigma, and discrimination in female HIV prevention.
