Mindfulness therapy for patients with coronary heart disease: A systematic review and meta-analysis.

AIM: Coronary heart disease (CHD) is a prevalent cardiovascular disease with high mortality rates worldwide. Patients with CHD often experience adverse psychological stress related to the disease's diagnosis, treatment and recovery phases. This stress can hurt sleep quality and overall quality of life. Mindfulness-based interventions (MBIs) have been studied as a psychotherapeutic approach to alleviating the psychological stress associated with CHD. This study aimed to determine the effectives of MBIs for health outcomes in patients with CHD. METHODS: A total of eight English-language databases were searched, and eight relevant studies were included in the analysis. The included studies were assessed for literature quality, and data were extracted and analysed using Review Manager 5.3. RESULTS: A total of eight studies involving 802 participants were included in the analysis. Compared to control groups, MBIs significantly reduced anxiety, depression, perceived stress, and systolic blood pressure. However, there was no significant effect on diastolic blood pressure, quality of life or body mass index. One study reported that MBIs significantly improved sleep quality in patients with acute myocardial infarction after percutaneous coronary intervention but had no significant effect on body mass index. CONCLUSION: MBIs had significant effects on anxiety and depression in patients with CHD, reduced perceived stress and were associated with reductions in systolic blood pressure and improvements in sleep quality. However, they did not significantly affect diastolic blood pressure, quality of life or body mass index.

Nutritional management interventions and multi-dimensional outcomes in frail and pre-frail older adults: A systematic review and meta-analysis.

BACKGROUND: Frailty, a prevalent geriatric syndrome, presents challenges exacerbated by malnutrition. Nutritional Management Interventions (NMIs) offer hope in frailty reversal, necessitating exploration of their multi-dimensional outcomes. OBJECTIVES: Assess NMIs' impact on frail and pre-frail older adults across diverse outcomes. METHODS: A systematic review and meta-analysis of 13 studies (2012-2023) evaluated NMIs' effects on physical, dietary, psychological, and frailty aspects. Literature quality was assessed, and data analyzed with Review Manager 5.3. RESULTS: A total of 13 studies involving participants were included in the analysis. Participants numbered 968, with the intervention group averaging 77.05±0.77 years and the control group 78.75±0.8 years. Compared to control groups,NMIs significantly increased body weight (SMD = 0.26, P = 0.03) and improved gait speed (SMD = 0.18, P = 0.03). Protein intake showed significance for interventions≤12 weeks (SMD = 1.04, P < 0.001). No significant differences in energy intake (SMD = 0.20, P = 0.60), but >12 weeks NMIs reduced energy intake (SMD = -0.73, P = 0.006). No significant differences in depressive symptoms, frailty scores, BMI, TUG, Handgrip Strength, or SPPB. CONCLUSION: This meta-analysis underscores NMIs' potential benefits for frail and pre-frail older adults. Personalized, multidimensional interventions are recommended despite study limitations, emphasizing extended interventions and diverse assessments for holistic care.

Incidence and risk factors of asymptomatic bacteriuria in patients with type 2 diabetes mellitus: a meta-analysis.

BACKGROUND: The prevalence of type 2 diabetes mellitus (T2DM) is increasing each year and has become one of the most prominent health concerns worldwide. Patients with T2DM are prone to infectious diseases, and urinary tract infections are also widespread. Despite a comprehensive understanding of urinary tract infection (UTI), there is a lack of research regarding primary prevention strategies for asymptomatic bacteriuria (ASB). OBJECTIVE: To clarify the incidence and risk factors of asymptomatic urinary tract infection in patients with T2DM by meta-analysis to provide evidence for preventing UTI. Help patients, their families, and caregivers to identify the risk factors of patients in time and intervene to reduce the incidence of ASB in patients with T2DM. Fill in the gaps in existing research. STUDY DESIGN: Meta-analyses were conducted in line with PRISMA guidelines. METHODS: Eleven databases were systematically searched for articles about ASB in T2DM, and the retrieval time was selected from the establishment of the database to February 5, 2023. Literature screening, quality evaluation, and meta-analysis were independently performed by two researchers according to the inclusion and exclusion criteria, and a meta-analysis was performed using Stata 17.0. RESULTS: Fourteen articles were included, including cohort and case-control studies. A meta-analysis of 4044 patients with T2DM was included. The incidence of ASB in patients with T2DM was 23.7%(95% CI (0.183, 0.291); P < 0.001). After controlling for confounding variables, the following risk factors were associated with ASB in patients with T2DM: age (WMD = 3.18, 95% CI (1.91, 4.45), I2 = 75.5%, P < 0.001), female sex (OR = 1.07, 95% CI(1.02, 1.12), I2 = 79.3%, P = 0.002), duration of type 2 diabetes (WMD = 2.54, 95% CI (1.53, 5.43), I2 = 80.7%, P < 0.001), HbA1c (WMD = 0.63, 95% CI (0.43, 0.84), I2 = 62.6,%. P < 0.001), hypertension (OR = 1.59, 95% CI (1.24, 2.04), I2 = 0%, <0.001), hyperlipidemia (OR = 1.66, 95% CI (1.27, 2.18), I2 = 0%, P < 0.001), Neuropathy (OR = 1.81, 95% CI (1.38, 2.37), I2 = 0%, P < 0.001), proteinuria (OR = 3.00, 95% CI (1.82, 4.95), I2 = 62.7%, P < 0.001). CONCLUSION: The overall prevalence of ASB in T2DM is 23.7%. Age, female sex, course of T2DM, HbA1C, hypertension, hyperlipidemia, neuropathy, and proteinuria were identified as related risk factors for ASB in T2DM. These findings can provide a robust theoretical basis for preventing and managing ASB in T2DM.

Di-n-butyl phthalate induces oversecretion of vascular endothelium-derived NAP-2 and promotes epithelial-mesenchymal transition of urothelial cells in newborn hypospadias rats.

Di-n-butyl phthalate (DBP) is a plasticizer commonly used in industrial production and is present in our daily life. It has been confirmed that DBP causes genitourinary malformations, especially hypospadias. However, the research of hypospadias mainly focusses on the genital tubercle in previous studies. In this study, we found DBP could affect the exocrine function of the vascular endothelium which disturb the development of genital nodules and induced hypospadias. We used cytokine array to find that vascular endothelium-derived NAP-2 may be a major abnormal secreted cytokine with biological functions. The transcriptomic sequencing analysis showed that abnormal activation of the RhoA/ROCK signaling pathway was the main reason for increased NAP-2 secretion. The expression levels of epithelial-mesenchymal transition (EMT) biomarkers and NAP-2 in hypospadias animal models were detected with Immunohistochemistry, Western blot, Immunofluorescence, and ELISA methods. The expression levels of NAP-2, RhoA/ROCK signaling pathway related proteins, reactive oxygen species (ROS) levels in HUVEC cells, EMT biomarkers and migration capacity of urothelial cells cocultured with HUVEC were measured with ELISA, flow cytometry, Western blot or Transwell assay for further cell experiments. The results showed that DBP leaded to NAP-2 oversecretion from vascular endothelium mainly rely on the activation of RhoA/ROCK signaling pathway and ROS accumulation. The RhoA/ROCK inhibitor fasudil could partially decrease ROS production, and both fasudil and N-acetyl-L-cysteine (NAC) could decrease NAP-2 secretion. Meanwhile, the oversecretion of NAP-2 from HUVEC in coculture system promoted EMT and migration capacity of urothelial cells, and TGF-ß inhibitor LY219761 could block the aberrant activation of EMT process. Therefore, it could be concluded that DBP increase NAP-2 secretion from vascular endothelium by RhoA/ROCK/ROS pathway, and further promote EMT in urothelial cells through TGF-ß pathway. This study provided a novel direction for studying the occurrence of hypospadias and may provide a hypospadias predictive marker in the future.

Effects of traditional Chinese exercises on the rehabilitation of patients with chronic heart failure: A meta-analysis.

Background: With the development of rehabilitation medicine, exercise therapy has gradually become one of the methods to prevent and treat cardiovascular diseases. It is widely used in clinic because it can further reduce the mortality rate, improve clinical symptoms, restore the activity ability of the body, improve the quality of life of patients and reduce the hospitalization rate. Traditional Chinese exercises have developed rapidly in recent years, which mainly include Baduanjin, Tai Ji, etc. However, meta-analyses of all types of exercises are not well characterized. Objectives: To evaluate the effect of traditional Chinese exercises (TCEs) on the rehabilitation of patients with chronic heart failure (CHF) using a meta-analysis. Methods: A systematic search of randomized controlled trials (RCTs) on TCEs for patients with CHF in 13 databases (PubMed, China National Knowledge Infrastructure, etc.). Meta-analysis was performed using Review Manager software (version 5.3) after two investigators independently screened the studies, assessed the quality of the studies, and extracted the data. Results: Meta-analysis of 21 randomized controlled trials which involved 1,665 patients with chronic heart failure showed that practicing TCEs was effective in improving patients' physiological outcomes such as VO2max [MD = 2.14, 95% CI (1.02, 3.26), P < 0.001], AT [MD = 1.61, 95% CI (1.06, 2.16), P < 0.001], and left ventricular ejection fraction [MD = 2.60, 95% CI (1.17, 4.02), P < 0.001]. Non-physiological outcomes benefited from the application of TCEs: 6-min walking distance [MD = 38.55, 95% CI (36.67, 40.42), P < 0.001], quality of life [MD = 5.52, 95% CI (3.17, 7.88), P < 0.001], and single-item TCM symptom scores in CHF patients: tiredness and fatigue [MD = 0.78, 95% CI (0.03, 1.53), P = 0.04], shortness of breath [MD = 0.44,95% CI (0.26, 0.62), P < 0.0001], facial puffiness and limb swelling [MD = 0.44,95% CI (0.12, 0.76), P = 0.007], palpitations [MD = 0.68,95% CI (0.14, 1.21), P = 0.01] were improved. Conclusions: TCEs improved several recovery indicators, heart failure-related clinical symptoms, quality of life, and physiological indicators in patients with CHF. It is worthwhile to expand the participants for practical application in clinical practice, but the existing evidence is insufficient and the heterogeneity of outcome is large. Therefore, more high-quality clinical trials are needed to support these results. Systematic review registration: PROSPERO, identifier [CRD42022383246].
