The ability of decline in intrinsic capacity to indicate the risk of mortality in older adults: A meta-analysis.

OBJECTIVE: To evaluate the ability of decline in intrinsic capacity to indicate the risk of mortality in older adults. DESIGN: Meta-analysis. METHODS: PubMed, EMBASE, Web of Science, the Cochrane Library, Wanfang Database, CNKI, VIP, and CBM were searched for relevant studies published from inception to October 31, 2023. Stata17.0 software was used to perform the meta-analysis. A random effects model was used to pool the results of the risk of mortality (as hazard ratios, HRs) in older adults and decline in intrinsic capacity. The Newcastle Ottawa Scale was used to evaluate the quality of studies. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system was used to determine the confidence in the estimated effect of pooled outcomes. RESULTS: Twelve studies, with a total of 38,531 participants, were included in this meta-analysis. The findings show that older adults with intrinsic capacity decline have a higher risk of mortality (HR = 1.11, 95 % CI 1.08-1.14, I2 = 95.9 %, P<0.001) than older adults with normal intrinsic capacity. The pooled HR estimates for the locomotion, vitality, and cognitive dimensions of intrinsic capacity in the prediction of mortality were 0.89 (HR = 0.89, 95%CI 0.83-0.96, I2 = 41.3 %, P = 0.146), 0.76 (HR = 0.98, 95 % CI 0.59-0.97, I2 = 60.8 %, P = 0.078), and 0.99 (HR = 0.99, 95 % CI 0.98-1.00, I2 = 0.0 %, P = 0.664), respectively. The pooled HR estimates of the psychological dimension to predict mortality were not statistically significant (P > 0.05). GRADE evaluations of outcome indicators were of moderate confidence. CONCLUSIONS: Decline in intrinsic capacity is a significant predictor of mortality. Locomotion, vitality, and cognition dimensions can all predict mortality. Clinical personnel should early assess the intrinsic capacity of older adults, focusing on changes in the dimensions of locomotion and vitality, to identify the risk of mortality, avoid adverse health outcomes, and improve the quality of life of older adults.

Flaxseed oil attenuates PFOS-induced testicular damage by regulating RNA alternative splicing.

Background: Perfluorooctane sulfonate (PFOS) is a persistent, widely present environmental pollutant, and its toxicity to male reproduction has gradually attracted attention. Flaxseed oil (FO) is a dietary oil abundant in α-linolenic acid and has been demonstrated to possess multiple health benefits. However, whether FO protects against PFOS-induced testicular injury and its mechanism remain unclear. Methods: C57/BL6 mice were gavaged with different concentrations of FO or PFOS (10 mg kg-1) for 28 days. Blood and testicular tissues were collected for histopathology, proteomics, and biochemical and molecular analyses. Results: Our results showed that FO supplementation significantly attenuated PFOS-induced testicular injury, as indicated by histopathological changes, decreased oxidative stress level, increased sperm count, decreased rate of sperm malformation, and improved functional markers of spermatogenesis. Proteomic analysis showed that differentially expressed proteins were notably enriched in spliceosome pathways. Machine learning algorithms were used to screen the hub gene, and PRPF3 and PUF60 proteins were found to be important for FO to exert protective benefits to testicular injury. Western blot results confirmed that FO supplementation could increase the protein expression of PRPF3 and decrease the protein expression of PUF60 in PFOS-exposed mice. Conclusions: This study revealed that FO can alleviate PFOS-induced testicular dysfunction by regulating RNA alternative splicing. The spliceosome-related proteins PRPF3 and PUF60 may be the potential targets for FO to alleviate PFOS-induced testicular injury. FO supplementation may be an effective dietary intervention to prevent adverse effects of PFOS on testes.

The relationship between arterial partial pressure of oxygen and pressure injuries in intensive care unit patients: A multi-center cross-sectional study.

BACKGROUND: Pressure injuries significantly impact patients in intensive care units and the healthcare system. Hypoxia, a major contributor to pressure injury development, can be promptly identified by monitoring arterial partial pressure of oxygen. However, the dose-response relationship between arterial partial pressure of oxygen and pressure injuries remains unclear. OBJECTIVES: To determine how mean arterial partial pressure of oxygen within 24 h before the appearance of a pressure injury influences pressure injury outcomes in ICU patients, elucidating the dose-response relationship, and underscoring the importance of including arterial oxygen pressure in routine pressure injury risk assessments. METHODS: We conducted this multi-center cross-sectional study in Gansu province of China from April 2021 to July 2023. The incidence and influencing factors of pressure injuries were collected. Logistic and restricted cubic spline regression analyses were used to assess the association between pressure injuries and arterial partial pressure of oxygen. Subgroup analyses stratified by age and sex were conducted to explore potential correlations. RESULTS: Among 6078 participants, the incidence of pressure injury was 2.34 %. After adjusting for all confounding factors, patients with low arterial partial pressure of oxygen were more likely to develop pressure injury than those with normal levels (OR 1.753, 95 %CI 1.142 âˆ¼ 2.693). The dose-response relationship shows a significant non-linear dose-response correlation between arterial partial pressure of oxygen and pressure injury risk (P = 0.011). Layered analysis shows that the impact is more pronounced in older individuals and males. CONCLUSIONS: As arterial partial pressure of oxygen decreases, the occurrence of pressure injuries gradually increases. Incorporating arterial partial pressure of oxygen into daily pressure injury risk assessments is crucial. IMPLICATIONS FOR CLINICAL PRACTICE: Our study results will offer targeted insights for the prevention and management of pressure injuries.

Improving Delphi Process in Acupuncture Decision Making: Overall Descriptions and Quality Assessment of Delphi Reports.

Background: Clinical acupuncture decisions are highly operator-dependent and require physician-patient interactions. The Delphi method allows subjective factors such as expert experience and preference of patients to be taken into account in clinical decision making, which is particularly applicable to acupuncture. Currently, the Delphi method is widely used to support clinical decisions in acupuncture. Therefore, it is necessary to provide high-quality and complete descriptions of the Delphi process when making clinical decisions. This study aims to evaluate the quality of the Delphi process in acupuncture, facilitate its standardization and rigor for further clinical decision making in acupuncture. Methods: Articles sourced from six databases were searched systematically to assess the quality of the Delphi consensus process based on the standards for conducting and reporting Delphi studies (CREDES). Descriptive statistics and analysis were presented according to the percentage of each item. Five-score Likert scale was used to evaluate the reporting quality of four domains as well as each item in CREDES by two independent researchers, combined with ICC-value to assess the consistency. Results: A total of 37 qualified articles were included according to eligibility criteria. As for the low reporting rate, the item "External validation" was reported as the lowest positive rate at 32.43% and the item "Prevention of bias" was 48.65%. The item "Adequacy of conclusions", "Definition and attainment of consensus", and "Discussion of limitations" were reported at a positive ratio of 62.16%, 64.86%, and 67.57% individually. The average scores of the four domains based on CREDES from highest to lowest were, respectively, as follows: planning and design (68.75%), reporting (66.07%), rationale for the choice of the Delphi technique (65.54%), study conduct (45.10%). Conclusion: The reporting quality of the Delphi consensus process in acupuncture is acceptable currently, but the reporting rate on some items is still low. Further standardization, including either clearer checklists or study reports, should be developed and strengthened to guide clinical decisions in acupuncture.

Conception vessel acupuncture research regularity in the treatment of diminished ovarian reserve: a multi-center, large-sample prospective cohort study protocol.

Background: Diminished ovarian reserve (DOR) refers to a decrease in the number or quality of oocytes in the ovarian cortex, which is a degenerative disease of the reproductive system, and can further develop into premature ovarian failure. There are few studies on acupuncture and moxibustion for DOR, which are still in the exploratory stage. Methods/design: This study was a real-world case registry study. According to whether the subjects received conception vessel acupuncture or not, they were divided into the basic treatment combined with conception vessel acupuncture group and the basic treatment group. A total of 1221 patients with DOR were enrolled and treated for 12 weeks. The percentage of patients with ≥30% improvement in anti-Müllerian hormone (AMH) was evaluated at the end of week 12. Secondary outcomes included Antral follicle count (AFC), modified Kupperman scale, basal FSH level, LH level, FSH/LH ratio, positive pregnancy, clinical pregnancy, early spontaneous abortion, ongoing pregnancy, and ectopic pregnancy. Discussion: This study provides clinical evidence and theoretical support for the treatment of DOR with conception vessel acupuncture and moxibustion, so as to guide and improve the efficacy of acupuncture and moxibustion. Trial registration: Acupuncture-Moxibustion Clinical Trial Registry ChiCTR2400080471. Registered on 30 January 2024.

Causal relationship between modifiable risk factors and knee osteoarthritis: a Mendelian randomization study.

Background: While several risk factors for knee osteoarthritis (KOA) have been recognized, the pathogenesis of KOA and the causal relationship between modifiable risk factors and KOA in genetic epidemiology remain unclear. This study aimed to determine the causal relationship between KOA and its risk factors. Methods: Data were obtained from published Genome-Wide Association study (GWAS) databases. A two-sample Mendelian randomization (MR) analysis was performed with genetic variants associated with risk factors as instrumental variables and KOA as outcome. First, inverse variance weighting was used as the main MR analysis method, and then a series of sensitivity analyses were conducted to comprehensively evaluate the causal relationship between them. Results: Univariate forward MR analysis revealed that genetically predicted hypothyroidism, hyperthyroidism/thyrotoxicosis, educational level, income level, metabolic syndrome (MS), essential hypertension, height, hot drink temperature, diet (abstaining from sugar-sweetened or wheat products), and psychological and psychiatric disorders (stress, depression, and anxiety) were causally associated with KOA. Reverse MR exhibits a causal association between KOA and educational attainment. Multivariate MR analysis adjusted for the inclusion of potential mediators, such as body mass index (BMI), smoking, alcohol consumption, and sex, exhibited some variation in causal effects. However, hyperthyroidism/thyrotoxicosis had a significant causal effect on KOA, and there was good evidence that height, hypothyroidism, educational level, psychological and psychiatric disorders (stress, depression, and anxiety), and abstaining from wheat products had an independent causal relationship. The mediating effect of BMI as a mediator was also identified. Conclusion: This study used MR to validate the causal relationship between KOA and its risk factors, providing new insights for preventing and treating KOA in clinical practice and for developing public health policies.

The latest research progress: Active components of Traditional Chinese medicine as promising candidates for ovarian cancer therapy.

ETHNOPHARMACOLOGICAL RELEVANCE: Ovarian cancer ranks the first in the mortality of gynecological tumors. Because there are no obvious symptoms in the early stage of ovarian cancer, most patients are in the advanced stage of the disease at the time of diagnosis. The incidence of ovarian cancer is increasing year by year, and the incidence of ovarian cancer has a trend of younger age. In recent years. Traditional Chinese medicine (TCM) has a significant impact on improving the quality of life of cancer patients, reducing drug toxicity, preventing metastasis and recurrence, enhancing the efficacy of radiotherapy and chemotherapy, and prolonging survival time, so patients have benefited a lot. AIM OF THE STUDY: This review summarizes the mechanisms and molecular pathways through which active ingredients of TCM act in ovarian cancer. It explores the advantages of TCM in treating ovarian cancer. This review provides theoretical support for the use of TCM in the treatment of ovarian cancer, offering new perspectives for its clinical prevention and treatment. MATERIALS AND METHODS: This review conducted a literature search on PubMed, Web of Science, Wanfang Database, and China National Knowledge Infrastructure (CNKI) for relevant studies on TCM active ingredients in preventing ovarian cancer. The search terms included "ovarian cancer" combined with "Chinese herbal medicine," "Herbal medicine," "Traditional Chinese medicine," and "Active ingredients of Chinese medicine". Based on existing experimental and clinical research, the paper systematically summarized and analyzed the mechanisms of TCM in treating ovarian cancer. RESULTS: Active ingredients of TCM inhibit the occurrence and development of ovarian cancer through inducing tumor cell apoptosis, inhibiting tumor cell proliferation, suppressing tumor cell migration and invasion, inducing tumor cell autophagy, promoting epithelial-mesenchymal transition, and enhancing the efficacy of radiotherapy and chemotherapy drugs. Chinese medicine provides a comprehensive treatment option for ovarian cancer patients, synergizing with radiotherapy and chemotherapy drugs to enhance treatment effectiveness and introduce new hope and possibilities in clinical therapy. CONCLUSIONS: Active ingredients of TCM can inhibit the occurrence and development of ovarian cancer, but further clinical research is needed to support their application.

Temperature-Driven Dengue Transmission in a Changing Climate: Patterns, Trends, and Future Projections.

Dengue is a rapidly spreading mosquito-borne infectious disease that is sensitive to climate factors and poses a major public health concern worldwide. We analyzed dengue incidence trends and the relationship between annual mean minimum temperatures (AMMTs) and dengue incidence rates from 1990 to 2019 in 122 countries using the Global Burden of Disease and TerraClimate data sets. We also projected global dengue incidence rates under different carbon emission scenarios using temperature data from the Coupled Model Intercomparison Project Phase 6 (CMIP6) data set. Our results reveal a significant increase in global dengue cases from 1990 to 2019 and a positive correlation between temperature and dengue incidence. The association between AMMT and dengue incidence strengthened at temperatures exceeding 21°C. Central and eastern sub-Saharan Africa, as well as Oceania, were identified as the regions most sensitive to dengue; males and individuals aged 15-19 or 70-84 years were the most susceptible to dengue under rising temperatures. Our projections suggest that global dengue incidence will substantially increase by 2050 and 2100. By 2100, regions including Africa, the Arabian Peninsula, the southern United States, southern China, and island countries in the Pacific and Indian Oceans are projected to become year-round dengue-endemic under a high-emission climate scenario. Our findings underscore the importance of implementing effective measures to mitigate the impact of climate change on dengue transmission. Identifying high-risk areas and susceptible populations, along with understanding the projected expansion of dengue-endemic regions, will provide valuable guidance for targeted interventions to address this growing global health challenge in the face of changing climatic conditions.

Meta-analysis with trial sequential analysis investigating the impact of adjunctive electroacupuncture therapy on vascular mild cognitive impairment.

BACKGROUND: To systematically collect, evaluate, and synthesize evidence from randomized controlled trials (RCTs) supporting the use of electroacupuncture (EA) as an additional treatment option for Vascular mild cognitive impairment (VaMCI), a meta-analysis was carried out. METHODS: Electronic searches of eight databases were used to locate RCTs that evaluated EA as a VaMCI adjuvant therapy. The Cochrane Risk of bias was used to assess the included trials' methodological quality. Review Manager 5.4 was used to analyze the data. Trial sequential analysis (TSA) was conducted with the trial sequential analysis program. RESULTS: There were 15 RCTs with 1033 subjects in them. Compared to conventional therapy (CT) alone, the Montreal Cognitive Assessment (SMD 0.72, 95 percent CI [0.55, 0.88]), Mini-mental State Examination (SMD 0.73, 95 percent CI [0.60, 0.87]), and activities of daily living (SMD 0.83, 95 percent CI [0.54, 1.12]) were significantly improved while EA was used in conjunction with CT. The current studies exceeded the required information size, according to trial sequential analysis (TSA), demonstrating the reliability of EA adjuvant therapy VaMCI. CONCLUSIONS: According to the pooled data, EA as an adjunct therapy for the treatment of VaMCI increases clinical efficacy. Although the TSA confirms a stable conclusion, it is encouraged to conduct studies of the highest quality standards.

Exposure to volatile organic compounds and growth indicators in adolescents: Unveiling the association and potential intervention strategies.

Environmental pollutant is considered to be one of the important factors affecting adolescent growth. However, the effects of volatile organic compounds (VOCs) exposure on adolescent growth have not been assessed. Data from the National Health and Nutrition Examination Survey (NHANES) 2011-2018 was used to examine the associations between VOCs exposure and adolescent growth indicators through three statistical models. The mediating effect of bone mineral density (BMD) on these associations was examined. The potential pathways and key targets were identified by the network pharmacology analysis methods. This study included 746 adolescents. Three statistical methods consistently showed a negative correlation between VOCs exposure and adolescent growth indicators. Furthermore, BMD mediated the relationship between VOCs exposure and adolescent growth indicators, with mediated proportion ranging from 4.3 % to 53.4 %. Network pharmacology analysis found a significant enrichment in IL-17 signaling pathway. Moreover, the adverse effects of VOCs exposure on adolescent growth were observed to significantly attenuate in adolescents with high serum vitamin D levels. Our results suggested that VOCs exposure was an adverse factor affecting adolescent growth, with BMD playing a significant regulatory role, and IL-17 signaling pathway was the underlying mechanism. Vitamin D supplementation may be a viable strategy to prevent VOCs exposure from affecting adolescent growth.

Efficacy of tanshinone IIA in rat models with myocardial ischemia-reperfusion injury: a systematic mini-review and meta-analysis.

Background: Myocardial ischemia-reperfusion injury (MIRI) refers to severe damage to the ischemic myocardium following the restoration of blood flow, and it is a major complication of reperfusion therapy for myocardial infarction. Notably, drugs such as metoprolol have been utilized to reduce ischemia-reperfusion injury. Tanshinone IIA is a major constituent extracted from Salvia miltiorrhiza Bunge. Recently, tanshinone IIA has been studied extensively in animal models for controlling MIRI. Therefore, we conducted a meta-analysis on the application of tanshinone IIA in rat models with MIRI to evaluate the therapeutic effects of tanshinone IIA. Methods: A comprehensive search was conducted across PubMed, Web of Science, Embase, the Cochrane Library, the China National Knowledge Infrastructure database, the Wanfang database, and the Chinese Scientific Journal Database to gather studies on tanshinone IIA intervention in rat models with MIRI.We employed SYRCLE's risk of bias tool to assess study quality. The primary outcome indicators were superoxide dismutase (SOD) and malondialdehyde (MDA). Myocardial infarction area was a secondary outcome indicator. This study was registered at PROSPERO (registration number CRD 42022344447). Results: According to the inclusion and exclusion criteria, 15 eligible studies were selected from 295 initially identified studies. In rat models with MIRI, tanshinone IIA significantly increased SOD levels while reducing MDA levels and myocardial infarction area. Moreover, the duration of myocardial ischemia influenced the effectiveness of tanshinone IIA. However, additional high-quality research studies are needed to establish the efficacy and definitive guidelines for the use of tanshinone IIA. Animal studies demonstrated that tanshinone IIA exerted a significant therapeutic effect when the ischemia duration was less than 40 minutes. Tanshinone IIA was found to be more effective when administered via intravenous, intraperitoneal, and intragastric routes at doses above 5 mg/kg. Additionally, treatment with tanshinone IIA at all stages-prior to myocardial ischemia, after ischemia but before reperfusion, prior to ischemia and after reperfusion, and after reperfusion-showed satisfactory results. Conclusions: Tanshinone IIA enhanced SOD activity and reduced MDA levels, thereby ameliorating oxidative stress damage during MIRI. Additionally, it reduced the myocardial infarction area, indicating its effectiveness in mitigating MIRI-induced damage in rats and demonstrating a myocardial protective effect. These findings contribute valuable insights for developing MIRI treatment strategies.

Preliminary evidence for the presence of programmed cell death in pressure injuries.

Pressure injuries (PIs) are a common healthcare problem worldwide and are considered to be the most expensive chronic wounds after arterial ulcers. Although the gross factors including ischemia-reperfusion (I/R) have been identified in the etiology of PIs, the precise cellular and molecular mechanisms contributing to PIs development remain unclear. Various forms of programmed cell death including apoptosis, autophagy, pyroptosis, necroptosis and ferroptosis have been identified in PIs. In this paper, we present a detailed overview on various forms of cell death; discuss the recent advances in the roles of cell death in the occurrence and development of PIs and found much of the evidence is novel and based on animal experiments. Herein, we also state critical evaluation of the existing data and future perspective in the field. A better understanding of the programmed cell death mechanism in PIs may have important implications in driving the development of new preventive and therapeutic strategies.

Mechanism, Formulation, and Efficacy Evaluation of Natural Products for Skin Pigmentation Treatment.

Skin pigmentation typically arises from the excessive secretion and accumulation of melanin, resulting in a darker complexion compared to normal skin. Currently, the local application of chemical drugs is a first-line strategy for pigmentation disorders, but the safety and efficacy of drugs still cannot meet clinical treatment needs. For long-term and safe medication, researchers have paid attention to natural products with higher biocompatibility. This article begins by examining the pathogenesis and treatment approaches of skin pigmentation diseases and summarizes the research progress and mechanism of natural products with lightening or whitening effects that are clinically common or experimentally proven. Moreover, we outline the novel formulations of natural products in treating pigmentation disorders, including liposomes, nanoparticles, microemulsions, microneedles, and tocosomes. Finally, the pharmacodynamic evaluation methods in the study of pigmentation disorder were first systematically analyzed. In brief, this review aims to collect natural products for skin pigmentation treatment and investigate their formulation design and efficacy evaluation to provide insights for the development of new products for this complex skin disease.

Unravelling the Metabolic Underpinnings of Gestational Diabetes Mellitus: A Comprehensive Mendelian Randomisation Analysis Identifying Causal Metabolites and Biological Pathways.

BACKGROUND: Gestational diabetes mellitus (GDM) has a strong genetic predisposition. Integrating metabolomics with Mendelian randomisation (MR) analysis offers a potent method to uncover the metabolic factors causally linked to GDM pathogenesis. OBJECTIVES: This study aims to identify specific metabolites and metabolic pathways causally associated with GDM susceptibility through a comprehensive MR analysis. Additionally, it seeks to explore the potential of these identified metabolites as circulating biomarkers for early GDM detection and risk assessment. Furthermore, it aims to evaluate the implicated metabolic pathways as potential therapeutic targets for preventive or interventional strategies against GDM. METHODS: A two-sample MR study was conducted using summary statistics from a metabolite genome-wide association study (GWAS) of 8299 individuals and a GDM GWAS comprising 13,039 cases and 197,831 controls. Rigorous criteria were applied to select robust genetic instruments for 850 metabolites. RESULTS: MR analysis revealed 47 metabolites exhibiting putative causal associations with GDM risk. Among these, five metabolites demonstrated statistically significant associations after multiple-testing correction: Beta-citrylglutamate, Isobutyrylcarnitine (c4), 1,2-dilinoleoyl-GPC (18:2/18:2), Alliin and Cis-3,4-methyleneheptanoylcarnitine. Importantly, all these metabolites exhibited protective effects against GDM development. Additionally, metabolic pathway enrichment analysis implicated the methionine metabolism and spermidine and spermine biosynthesis pathways in the pathogenesis of GDM. CONCLUSION: This comprehensive MR study has robustly identified specific metabolites and metabolic pathways with causal links to GDM susceptibility. These findings provide novel insights into the metabolic underpinnings of GDM aetiology and offer promising translational implications. The identified metabolites could serve as potential circulating biomarkers for early detection and risk stratification, while the implicated metabolic pathways may represent therapeutic targets for preventive or interventional strategies against GDM.

SAP130 mediates crosstalk between hepatocyte ferroptosis and M1 macrophage polarization in PFOS-induced hepatotoxicity.

Perfluorooctane sulfonate (PFOS) is a persistent organic pollutant widely utilized in industrial manufacturing and daily life, leading to significant environmental accumulation and various public health issues. This study aims to characterize spliceosome-associated protein 130 (SAP130) as a key mediator of crosstalk between hepatocytes and macrophages, elucidating its role in PFOS-induced liver inflammation. The data demonstrate that PFOS exposure induces ferroptosis in mouse liver and AML12 cells. During ferroptosis, SAP130 is released from injured hepatocytes into the microenvironment, binding to macrophage-inducible C-type lectin (Mincle) and activating the Mincle/Syk signaling pathway in macrophages, ultimately promoting M1 polarization and exacerbating liver injury. Treatment with the ferroptosis inhibitor Ferrostatin-1 reduces SAP130 release, inhibits Mincle/Syk signaling activation, and mitigates inflammatory response. Furthermore, siSAP130 suppresses the activation of the Mincle signaling pathway and M1 polarization in BMDM cells. Conversely, treatment with the ferroptosis agonist Erastin enhances paracrine secretion of SAP130 and exacerbates inflammation. These findings emphasize the significance of hepatocyte-macrophage crosstalk as a critical pathway for PFOS-induced liver injury in mice while highlighting SAP130 as a pivotal regulator of ferroptosis and inflammation, thereby elucidating the potential mechanism of PFOS-induced liver injury.

Efficacy and safety of Shen Que (RN8) moxibustion on reproductive outcomes in unexpected poor ovarian responders: a randomized controlled trial.

BACKGROUND: Managing infertility patients with poor ovarian response (POR) to ovarian stimulation remains unmet clinically. Besides economic burdens, patients with POR have a poor prognosis during in vitro fertilization and embryo transfer (IVF-ET). In this study, we assessed the efficacy and safety of Shen Que (RN8) moxibustion on reproductive outcomes in POSEIDON patients (Group 2a). METHODS: Women eligible for IVF were invited to participate in this randomized, open-label, superiority trial at an academic fertility center from January 2022 to December 2023. One hundred patients ≤ 44 years old equally divided between Shen Que moxibustion (SQM) and control groups were randomized. These patients must meet the POSEIDON criteria, Group 2a, which requires antral follicle count (AFC) ≥ 5 or anti-müllerian hormone (AMH) ≥ 1.2ng/ml, and a previous unexpected POR (< 4 oocytes). Twelve moxibustion sessions were conducted in the SQM group prior to oocyte retrieval, while only IVF treatment was performed in the control group. The primary outcome was the number of oocytes retrieved. RESULTS: As compared with the IVF treatment alone, the SQM + IVF treatment significantly increased the number of retrieved oocytes (4.7 vs. 5.8, p = 0.012), mature oocytes (3.0 vs. 5.0, p = 0.008), and available embryos (2.0 vs. 4.0, p = 0.014) in unexpected poor ovarian responders aged more than 35 years. In the SQM group, the cumulative live birth rate was 27.3% (9/33) in comparison to 13.3% (4/30) in the control group, whereas no statistical significance was detected (p = 0.172). During the study, no significant adverse effects were observed. CONCLUSIONS: Women with unexpected POR who meet POSEIDON Group 2a can benefit from Shen Que (RN8) moxibustion treatment. TRIAL REGISTRATION: ClinicalTrials.gov, NCT05653557.

Intrinsic capacity decline as a predictor of functional disability in the elderly: A systematic review and meta-analysis.

OBJECTIVES: To examine the predictive value of intrinsic capacity decline on functional disability among the elderly. DESIGN: Meta-analysis. METHODS: PubMed, EMBASE, Web of Science, The Cochrane Library, Wanfang Database, China Knowledge Resource Integrated Database (CNKI), Weipu Database (VIP), and Chinese Biomedical Database (CBM) were searched for relevant studies published from the inception until June 1, 2024. Stata 17.0 software was used to perform the meta-analysis. The methodological quality was evaluated using the Newcastle Ottawa Scale. The overall quality of evidence used GRADE guidelines to assess. A study protocol was registered in PROSPERO (CRD42023475461). RESULTS: The meta-analysis included 8 cohort studies including 9744 elderly people. Functional disability including ADL disability (n = 6) and IADL disability (n = 7). The results showed that intrinsic capacity decline could predict ADL disability (HR = 1.08, 95 %CI 1.04-1.12; I2 = 98.2 %, P < 0.001) and IADL disability (HR = 1.11, 95 %CI 1.05-1.17; I2 = 96.4 %, P < 0.001). The overall risk of bias was low. And the grade of evidence that assessed by GRADE guidelines was rated as moderate. CONCLUSIONS: Intrinsic capacity decline is a predictor of functional disability in the elderly. Therefore, screening intrinsic capacity decline has important clinical implications for early identifying the risk of functional disability, which contributes to providing individualized interventions ahead of potential functional disability for the elderly, thereby preventing functional disability, improving the quality of life and promoting healthy aging.

Repetitive transcranial magnetic stimulation as a therapy for post-stroke dysphagia: An overview of systematic reviews and meta-analysis.

OBJECTIVE: Post-stroke dysphagia is a common swallowing disorder that occurs after a stroke, leading to an increased risk of aspiration pneumonia and malnutrition. There is a pressing need for effective and safe interventions for its rehabilitation. This review aims to answer two key scientific questions: (1) What is the efficacy of repetitive transcranial magnetic stimulation in the rehabilitation of post-stroke dysphagia? (2) Is repetitive transcranial magnetic stimulation a safe intervention for post-stroke dysphagia? DATA SOURCES: A comprehensive search was conducted across four electronic databases: PubMed, Cochrane Library, Web of Science, and Embase. The search aimed to identify relevant studies concerning our topic of interest and was completed on 28 May 2024. REVIEW METHODS: In accordance with the PRISMA checklist, a comprehensive search of four databases was conducted, which identified 13 relevant systematic reviews. The inclusion criteria were systematic reviews that evaluated the efficacy and safety of repetitive transcranial magnetic stimulation for post-stroke dysphagia. Exclusion criteria were reviews that did not focus on post-stroke dysphagia or did not evaluate repetitive transcranial magnetic stimulation as a therapeutic intervention. The quality, bias, reporting, and overall evidence quality of these reviews were assessed using validated tools, including the AMSTAR 2 tool for assessing the methodological quality of systematic reviews, the ROBIS tool for assessing the risk of bias, and the GRADE approach for evaluating the overall quality of evidence. This rigorous approach ensures that our review provides a comprehensive and reliable overview of the current state of knowledge on the use of repetitive transcranial magnetic stimulation for post-stroke dysphagia. RESULTS: The sample sizes for the individual studies included in the systematic reviews/meta-analyses ranged from 66 to 555. The total number of participants across all studies included in the overall analyses was 752. The evidence was limited by the methodological flaws and heterogeneity of the systematic reviews. The quality of the evidence varied from high to low, with most outcomes having moderate quality. Future research should adopt more rigorous, standardized, and comprehensive designs to confirm the efficacy and safety of repetitive transcranial magnetic stimulation for post-stroke dysphagia. The main reason for downgrading the evidence quality was the small sample size and high heterogeneity of the primary studies. CONCLUSION: This overview synthesized research on repetitive transcranial magnetic stimulation for dysphagia, aiming to inform clinical and policy decisions. However, the current evidence does not conclusively establish the safety and efficacy of repetitive transcranial magnetic stimulation for post-stroke dysphagia rehabilitation. The studies reviewed varied in quality, and many were of poor quality. Therefore, while some studies suggest potential benefits of repetitive transcranial magnetic stimulation, these findings should be interpreted with caution. There is a pressing need for more rigorous, high-quality research to validate the use of repetitive transcranial magnetic stimulation for post-stroke dysphagia rehabilitation. The implications of these findings for clinical practice and policy will be clearer once we have more robust, evidence-based recommendations.

Evaluation of the risk prediction model of pressure injuries in hospitalized patient: A systematic review and meta-analysis.

AIMS AND OBJECTIVES: The main aim of this study is to synthesize the prevalent predictive models for pressure injuries in hospitalized patients, with the goal of identifying common predictive factors linked to pressure injuries in hospitalized patients. This endeavour holds the potential to provide clinical nurses with a valuable reference for providing targeted care to high-risk patients. BACKGROUND: Pressure injuries (PIs) are a frequently occurring health problem throughout the world. There are mounting studies about risk prediction model of PIs reported and published. However, the prediction performance of the models is still unclear. DESIGN: Systematic review and meta-analysis: The Cochrane Library, PubMed, Embase, CINAHL, Web of Science and Chinese databases including CNKI (China National Knowledge Infrastructure), Wanfang Database, Weipu Database and CBM (China Biology Medicine). METHODS: This systematic review was conducted following PRISMA recommendations. The databases of Cochrane Library, PubMed, Embase, CINAHL, Web of Science, and CNKI, Weipu Database, Wanfang Database and CBM were searched for all studies published before September 2023. We included studies with cohort, case-control designs, reporting the development of risk model and have been validated externally and internally among the hospitalized patients. Two researchers selected the retrieved studies according to the inclusion and exclusion criteria, and critically evaluated the quality of studies based on the CHARMS checklist. The PRISMA guideline was used to report the systematic review and meta-analysis. RESULTS: Sixty-two studies were included, which contained 99 pressure injuries risk prediction models. The AUC (area under ROC curve) of modelling in 32 prediction models were reported ranged from .70 to .99, while the AUC of verification in 38 models were reported ranged from .70 to .98. Gender (OR = 1.41, CI: .99 ~ 1.31), age (WMD = 8.81, CI: 8.11 ~ 9.57), diabetes mellitus (OR = 1.64, CI: 1.36 ~ 1.99), mechanical ventilation (OR = 2.71, CI: 2.05 ~ 3.57), length of hospital stay (WMD = 7.65, CI: 7.24 ~ 8.05) were the most common predictors of pressure injuries. CONCLUSION: Studies of PIs risk prediction model in hospitalized patients had high research quality, and the risk prediction models also had good predictive performance. However, some of the included studies lacked of internal or external validation in modelling, which affected the stability and extendibility. The aged, male patient in ICU, albumin, haematocrit, low haemoglobin level, diabetes, mechanical ventilation and length of stay in hospital were high-risk factors for pressure injuries in hospitalized patients. In the future, it is recommended that clinical nurses, in practice, select predictive models with better performance to identify high-risk patients based on the actual situation and provide care targeting the high-risk factors to prevent the occurrence of diseases. RELEVANCE TO CLINICAL PRACTICE: The risk prediction model is an effective tool for identifying patients at the risk of developing PIs. With the help of risk prediction tool, nurses can identify the high-risk patients and common predictive factors, predict the probability of developing PIs, then provide specific preventive measures to improve the outcomes of these patients.
