Characteristics and quality of clinical practice guidelines for diabetic kidney disease: a systematic review.

To assess the quality of Clinical practice guidelines (CPGs) in the context of diabetic kidney disease (DKD) and determine whether any factors affect the quality. We searched eight databases along with five international and national organizations to develop or archive guidelines from their inception to July 2023, with an additional search of medlive.cn. And the authoritative organizations related to nephrology. CPGs and consensus statements created using direct differential diagnosis or therapy for DKD were included without language restrictions. Their quality was evaluated by four reviewers using the Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ) instrument. Along with the item and domain scores, the guideline was also allocated an overall quality score, which ranged from 1 (lowest possible quality) to 7 (highest possible quality). Moreover, an overall recommendation for use was also assigned ("recommended", "recommended with modifications" or "not recommended"). A total of 16 CPGs were included, of which 14 were from Asia and the remaining two from Europe. These two CPGs were updated in the third version. Six CPGs were recommended for use because their primary domains scored in the medium or high category. Furthermore, five CPGs were recommended with modifications as the stakeholder involvement, applicability, and editorial independence domains were evaluated as low categories. In all domains, the lowest average score was for rigour of development (33%), followed by application (36%), and stakeholder involvement (51%). The highest average score was for scope and purpose (79%), followed by clarity of presentation (75%). None of the CPGs considered the patient's viewpoint, and six of 16 CPGs did not use any grading system to translate the evidence into recommendations. Additionally, only three of 16 CPGs shared search strategy, and eight of 16 CPGs did not declare a funding source. According to the AGREE II evaluation, more than one in four CPGs for DKD had poor methodological quality. Enhanced efforts are needed to advance the rigour of development, application, and editorial independence of DKD guideline panels for most guidelines. Stakeholders, CPG developers, and CPG users should consider methodological quality while choosing CPGs, and interpret and implement their issued suggestions.

Effects of stress management interventions on heart rate variability in adults with cardiovascular disease: a systematic review and meta-analysis.

Meta-analysis was used to investigate the potential benefits of stress management interventions (SMIs) on vagally-mediated heart rate variability (HRV) in adults with cardiovascular disease. Electronic bibliographic databases were searched through August 2022. Randomized controlled trials and quasi-experimental studies assessing effects of SMIs on HRV were included. Methodological quality was assessed with a standardized checklist. A pooled effect size was calculated for vagally-mediated HRV indices (standard deviation of normal-to-normal intervals, root mean square of the successive differences, and high frequency power) using random effects models. Fourteen studies (1202 participants, Mage: 59 ± 6.25years; 25% ± 16% women; 61% ± 22% White) were included. Ten studies (11 effects) reported short-term HRV assessment; a small between-group difference emerged for vagally-mediated HRV (d+ = .27, 95% confidence interval [CI] 0.01-0.52, k = 11). Most interventions examined biofeedback; these studies yielded a small between-group difference on vagally-mediated HRV (d+ = 0.31, 95% CI 0.09-0.53, k = 7, Q [6] = 3.82, p = .70, I2 = 11%). This is the first systematic examination of the effect of SMIs on HRV in adults with CVD. Findings suggest a small effect of SMIs on vagally-mediated HRV, with biofeedback likely driving the effect. More research is required to fully understand whether this benefit on vagally-mediated HRV applies to other SMIs.

Start with muscle mass or muscle strength in diagnosis and management of sarcopenia? A systematic review of guidance documents.

Sarcopenia has garnered extensive attention in clinical practice since its high prevalence and significant impact on clinical outcomes. Multiple organizations have published guidance documents on sarcopenia, offering evidence-based recommendations for clinical practice and/or research. We aimed to appraise the methodological quality of the included documents and synthesize available recommendations for the screening, diagnosis, and intervention of sarcopenia. We conducted a search on PubMed, Embase, Scopus, Cochrane Library, China National Knowledge Infrastructure, guideline database, and guideline organizations and professional societies websites for clinical practices, consensus statements and position papers in terms of sarcopenia, muscle atrophy or muscle loss published before April 17, 2023. The AGREE II instrument was used by three independent reviewers to assess the methodological quality of these documents. Thirty-six guidance documents published between 2010 and 2023 were included. Seven documents fulfilled ≥ 50% of all the AGREE II domains. Seven underwent a Delphi process and six graded the strength of the recommendations. The process of screening (n=21), early diagnosis of sarcopenia (n=12), diagnosis of sarcopenia and severe sarcopenia (n=10), and management (n=21) were increasingly recommended. SARC-F (n=14) was the most recommended screening tool, and the assessment of muscle function was considered the first step in diagnosing sarcopenia. The management strategy for both age-related and disease-related sarcopenia mainly focused on exercise and nutrition intervention. The guidance documents have provided referential recommendations that have great guiding significance. But the inconsistency in recommendations and variation in methodological rigour suggests that high-quality evidence is lacking yet.

How consistent are the key recommendations, and what is the quality of guidelines and expert consensus regarding paediatric cow's milk protein allergy?

The objective of this study was to assess the quality and consistency of recommendations in clinical practice guidelines (CPGs) and expert consensus on paediatric cow's milk protein allergy (CMPA) to serve as a foundation for future revisions and enhancements of clinical guidelines and consensus documents. We conducted a comprehensive literature search across several databases, including the Chinese Biomedical Literature Database (CBM), PubMed, Embase, Web of Science, UpToDate, ClinicalKey, DynaMed Plus and BMJ Best Practice. We spanned the search period from the inception of each database through October 1, 2023. We integrated subject headings (MeSH/Emtree) and keywords into the search strategy, used the search methodologies of existing literature and developed it in collaboration with a librarian. Two trained researchers independently conducted the literature screening and data extraction. We evaluated methodological quality and recommendations by using the Appraisal of Guidelines for Research & Evaluation II (AGREE II) and AGREE-Recommendations for Excellence (AGREE-REX) tools. Moreover, we compared and summarized key recommendations from high-quality CPGs. Our study included 27 CPGs and expert consensus documents on CMPA. Only four CPGs (14.8%) achieved a high-quality AGREE II rating. The four high-quality CPGs consistently provided recommendations for CMPA. The highest scoring domains for AGREE II were 'scope and purpose' (77 ± 12%) and 'clarity of presentation' (75 ± 22%). The lowest scoring domains were 'stakeholder involvement' (49 ± 21%), 'rigor of development' (34 ± 20%) and 'applicability' (12 ± 20%). Evaluation with AGREE-REX generally demonstrated low scores across its domains. Conclusion: Recommendations within high-quality CPGs for the paediatric CMPA showed fundamental consistency. Nevertheless, the methodology and recommendation content of CPGs and the expert consensus exhibited low quality, thus indicating a substantial scope for enhancement. Guideline developers should rigorously follow the AGREE II and AGREE-REX standards in creating CPGs or expert consensuses to guarantee their clinical efficacy in managing paediatric CMPA. What is Known: • The quality of clinical practice guidelines and expert consensus on paediatric cow's milk protein allergy (CMPA) remains uncertain. • There is a lack of clarity regarding the consistency of crucial recommendations for CMPA management. What is New: • Improving the methodological quality of guidelines and consensus on CMPA requires greater emphasis on stakeholder engagement, rigorous development processes, and practical applicability. • The recommendations from four high-quality guidelines align. However, addressing clinical applicability, integrating values and preferences, and ensuring actionable implementation are critical to improving the quality of all guidelines.

Effects of repetitive transcranial magnetic stimulation in children and young people with psychiatric disorders: a systematic review.

Repetitive transcranial magnetic stimulation (rTMS) has demonstrated benefits in adults with psychiatric disorders, but its clinical utility in children and young people (CYP) is unclear. This PRISMA systematic review used published and ongoing studies to examine the effects of rTMS on disorder-specific symptoms, mood and neurocognition in CYP with psychiatric disorders. We searched Medline via PubMed, Embase, PsychINFO via OVID, and Clinicaltrials.gov up to July 2023. Eligible studies involved multiple-session (i.e., treatment) rTMS in CYP (≤ 25 years-old) with psychiatric disorders. Two independent raters assessed the eligibility of studies and extracted data using a custom-built form. Out of 78 eligible studies (participant N = 1389), the majority (k = 54; 69%) reported an improvement in at least one outcome measure of disorder-specific core symptoms. Some studies (k = 21) examined rTMS effects on mood or neurocognition,: findings were largely positive. Overall, rTMS was well-tolerated with minimal side-effects. Of 17 ongoing or recently completed studies, many are sham-controlled RCTs with better blinding techniques and a larger estimated participant enrolment. Findings provide encouraging evidence for rTMS-related improvements in disorder-specific symptoms in CYP with different psychiatric disorders. However, in terms of both mood (for conditions other than depression) and neurocognitive outcomes, evidence is limited. Importantly, rTMS is well-tolerated and safe. Ongoing studies appear to be of improved methodological quality; however, future studies should broaden outcome measures to more comprehensively assess the effects of rTMS and develop guidance on dosage (i.e., treatment regimens).

Unraveling the Determinants of Maternal Well-Being Among Tribal Populations of Kerala: A Systematic Review.

Despite Kerala's noteworthy achievements in health indices, the tribal population in the state continues to face significant challenges in achieving optimal health outcomes. This is particularly evident in the realm of maternal health, where tribal communities struggle. In light of this paradox, a systematic review was conducted to identify the factors influencing the quality of tribal maternal health and their determinants. A comprehensive search strategy was employed, utilizing computer-backed searches of eminent bibliographic databases, along with the exploration of additional cited references and hand-searching of relevant journals. The methodological quality of the selected studies was rigorously assessed through a transparent cataloguing system and analysis by reviewers, resulting in the inclusion of thirty studies following the filtering process. The selected studies were subjected to detailed analysis to identify the determinants of maternal health among tribal populations. Thematic analysis of thirty studies that met the inclusion criteria resulted in four sets of determinants that contribute to maternal health among tribal women; biological/demographic determinants, psychological determinants, social determinants, and cultural determinants. This review provides a comprehensive picture of tribal maternal health in Kerala, shedding light on their multifaceted challenges. The study provides a basis for the formulation of initiatives by addressing the broader determinants of health and accounting unique socio-cultural factors influencing well-being of tribal communities.

Appraisal of clinical practice guidelines and consensus statements on obstetric anaesthesia: a systematic review using the AGREE II instrument

ObjectivesDespite the publication of hundreds of trials on obstetric anaesthesia, the management of these conditions remains suboptimal. We aimed to assess the quality and consistency of guidance documents for obstetric...

A pilot rating system to evaluate the quality of goal attainment scales used as outcome measures in rehabilitation

ABSTRACT Goal Attainment Scaling (GAS) is a method for writing person-centred approach evaluation scales that can be used as an outcome measure in clinical or research settings in rehabilitation. To be used in a research setting, it requires a high methodological quality approach. The aim of this study was to explore the feasibility and reliability of the GAS quality rating system, to ensure that GAS scales used as outcome measures are valid and reliable. Secondary objectives were: (1) to compare goal attainment scores’ reliability according to how many GAS levels are described in the scale; and (2) to explore if GAS scorings are influenced by who scores goal attainment. The GAS scales analysed here were set collaboratively by 57 cognitively impaired adults clients and their occupational therapist. Goals had to be achieved within an inpatient one-month stay, during which clients participated in an intervention aimed at improving planning skills in daily life. The GAS quality rating system proved to be feasible and reliable. Regarding GAS scores, interrater reliability was higher when only three of the five GAS levels were described, i.e., “three milestone GAS” (0.74–0.92), than when all five levels were described (0.5–0.88), especially when scored by the clients (0.5 –0.88).

Systematic review of healthcare interventions for reducing gender-based violence impact on the mental health of women with disabilities.

Women with disabilities are more exposed to violence. The health sector has a key role in all three levels of prevention of violence against women. The objective of this paper was to review the interventions for preventing gender-based violence and reducing its impact on the mental health of women with any form of disability. Relevant studies were identified through conducting searches in PubMed, Scopus, CINAHL, PsyInfo, Social Services Abstracts, and PILOTS. Two reviewers analyzed and selected studies. A qualitative synthesis was made. 3149 references were obtained, among which eight articles describing nine interventions from the USA and the UK. Most were intended for women with mental/intellectual disability and assessed intimate partner or sexual violence. Only one study showed high methodological quality. They were found to be particularly effective as regards improvement of the skills acquired by participants, but the results as regards improved mental health are not consistent. Our review shows very little evidence of effective interventions. Further studies are required with higher internal validity and female sample groups with diverse disabilities. Gender-based violence is a highly prevalent problem for women with disabilities, and in addition to being a public health challenge is a violation of human rights. Health care systems and policymakers should take a key role in all three levels of prevention of violence against women with disabilities. Interventions with longer follow-up times are required. It is also important for interventions to be designed in consultation with people with disabilities.

Transcutaneous bilirubinometry for detecting jaundice in term or late preterm neonates.

The American Academy of Pediatrics and the Canadian Paediatric Society both advise that all newborns should undergo bilirubin screening before leaving the hospital, and this has become the standard practice in both countries. However, the US Preventive Task Force has found no strong evidence to suggest that this practice of universal screening for bilirubin reduces the occurrence of significant outcomes such as bilirubin-induced neurologic dysfunction or kernicterus. To evaluate the effectiveness of transcutaneous screening compared to visual inspection for hyperbilirubinemia to prevent the readmission of newborns (infants greater than 35 weeks' gestation) for phototherapy. We searched CENTRAL, MEDLINE, Embase, CINAHL, ClinicalTrials.gov, ICTRP, and ISRCTN in June 2023. We also searched conference proceedings, and the reference lists of included studies. We included randomized controlled trials (RCTs), quasi-randomized, cluster-randomized, or prospective cohort studies with control arm that evaluated the use of transcutaneous bilirubin (TcB) screening for hyperbilirubinemia in newborns before hospital discharge. We used standard methodologic procedures expected by Cochrane. We evaluated treatment effects using a fixed-effect model with risk ratio (RR) and 95% confidence intervals (CI) for categorical data and mean, standard deviation (SD), and mean difference (MD) for continuous data. We used the GRADE approach to evaluate the certainty of evidence. We identified one RCT (1858 participants) that met our inclusion criteria. The study included 1858 African newborns at 35 weeks' gestation or greater who were receiving routine care at a well-baby nursery, and were randomly recruited prior to discharge to undergo TcB screening. The study had good methodologic quality. TcB screening versus visual assessment of hyperbilirubinemia in newborns: - may reduce readmission to the hospital for hyperbilirubinemia (RR 0.25, 95% CI 0.14 to 0.46; P < 0.0001; moderate-certainty evidence); - probably has little or no effect on the rate of exchange transfusion (RR 0.20, 95% CI 0.01 to 14.16; low-certainty evidence); - may increase the number of newborns who require phototherapy prior to discharge (RR 2.67, 95% CI 1.56 to 4.55; moderate-certainty evidence). - probably has little or no effect on the rate of acute bilirubin encephalopathy (RR 0.33, 95% CI 0.01 to 8.18; low-certainty evidence). The study did not evaluate or report cost of care. Moderate-certainty evidence suggests that TcB screening may reduce readmission for hyperbilirubinemia compared to visual inspection. Low-certainty evidence also suggests that TcB screening probably has little or no effect on the rate of exchange transfusion compared to visual inspection. However, moderate-certainty evidence suggests that TcB screening may increase the number of newborns that require phototherapy before discharge compared to visual inspection. Low-certainty evidence suggests that TcB screening probably has little or no effect on the rate of acute bilirubin encephalopathy compared to visual inspection. Given that we have only identified one RCT, further studies are necessary to determine whether TcB screening can help to reduce readmission and complications related to neonatal hyperbilirubinemia. In settings with limited newborn follow-up after hospital discharge, identifying newborns at risk of severe hyperbilirubinemia before hospital discharge will be important to plan targeted follow-up of these infants.

Wheeled mobility use outcomes: a systematic review of measurement properties protocol.

Numerous tools have been developed to measure constructs related to wheelchair use. Currently, no toolkit comprehensively details assessments of wheeled mobility device use based on the quality of their measurement properties. The current review aims to systematically identify high-quality assessment tools that measure different aspects of wheeled mobility use. The objectives are two-fold: (1) to synthesize outcome measures that assess use of wheeled mobility devices, and (2) to evaluate measurement properties of the assessment tools. The populations of interest are manual wheelchair users, power wheelchair users, and scooter users of any age, diagnosis, or setting. Instruments of any type will be included. The JBI methodology for systematic reviews of measurement properties will guide this review. A search strategy will be developed to search the following databases: MEDLINE (Ovid), Embase, CINAHL (EBSCOhost), PsycINFO (EBSCOhost), PsycTests (EBSCOhost), Web of Science, and Google Scholar. The article selection process, data extraction, and quality appraisal will be performed by 2 independent reviewers, with a third reviewer being consulted to achieve consensus. The methodological quality of the studies will be assessed through the Consensus Standards for the Selection of Measurement Instruments (COSMIN) Risk of Bias tool and the COSMIN Checklist. The quality of the pooled evidence and individual measurement properties will be graded using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach and the COSMIN Criteria for Good Measurement Properties recommendations. Measurement properties of each instrument will be described, with the goal of developing a toolkit that identifies appropriate assessment tools for wheeled mobility use outcomes. PROSPERO: CRD4202276169.

The efficacy of olfactory training in improving olfactory function: a meta-analysis.

Study the efficacy of olfactory training in smell recovery. An extensive search was performed through different databases in order to find articles analyzing the efficacy of olfactory training as a treatment for olfactory dysfunction. Methodological quality of primary studies within the final sample was assessed following PRISMA guidelines. Standardized mean differences in pre-post olfactory training groups, and also in experimental-control and pre-follow up if possible, were computed by Hedges' g effect size statistic. Each effect size was weighted by its inverse variance. Final sample was composed of 36 articles (45 pre-post effect sizes). Contrasts were performed separately for odor identification, odor discrimination, odor threshold and general olfactory function. Moderate to large and heterogeneous effect was obtained for olfactory function (g = 0.755, k = 45, SE = 0.093, CI 95% = [0.572, 0.937]), different moderators had a significant effects, such as, training duration, age and anosmia diagnosis. Olfactory training was found to have a positive and significant effect on rehabilitating the olfactory function.

Value of radiofrequency ablation for treating locally recurrent thyroid cancer: a systematic review and meta-analysis for 2-year follow-up.

To evaluate the safety and efficacy of radiofrequency ablation (RFA) in treating locoregional recurrent thyroid cancer (LRTC) after a 2-year follow-up time. PubMed, Embase and Cochrane Library were searched from inception until 20 September 2022 to find studies reporting the safety and efficacy of RFA in LRTC patients after a 2-year follow-up. Two radiologists performed the data extraction and methodological quality assessment according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We analyzed 6 studies, 229 LRTC patients with 319 locally recurrent tumors were treated with RFA. The mean follow-up time of each study was ≥24 months. The pooled changes in the largest diameter and volume were 7.22 mm (95% confidence interval (CI), 6.35-8.09 mm) and 164.28 mm3 (95% CI, 87.78-240.77 mm3), respectively; the pooled volume reduction rate was 95.03% (95% CI, 87.56-102.49%). The total complete disappearance rate after treatment was 92% (95% CI, 83-100%). The pooled decrease of serum thyroglobulin levels was 0.02 ng/ml (95% CI, -0.00-0.04 ng/ml). The pooled proportion of recurrence rate was 6% (95% CI, 0-13%). The pooled complication rate was 5% (95% CI, 0-10%). The major complications were voice change and hoarseness, only one patient developed permanent vocal cord paralysis; minor complications were cough and pain. Ultrasound-guided RFA is an effective and safe treatment for LRTC based on 2-year follow-up results.

Measurement properties of patient-reported outcome measures for women with dysmenorrhea: A systematic review.

Dysmenorrhea, or menstrual pain, is a subjective experience, and can only be assessed by patient-reported outcomes. These instruments should be reliable, valid and responsive. To identify and critically appraise the available evidence for the measurement properties of specific patient-reported outcome measures used for dysmenorrhea. The PRISMA statement was used to report this systematic review. Databases searched were PubMed, SCOPUS, CINAHL, Web of Science, ScienceDirect and Google Scholar (April 2021; updated on February 2023). Original studies with primary data collection, with no restriction on language and publication date that reported psychometric properties of one or more dysmenorrhea-related patient-reported outcome measure. The literature searches, selection of studies, data extraction and assessment of the risk of bias were performed independently by two reviewers and followed the COSMIN guidelines. Thirty studies were analysed in this review, and 19 patient-reported outcome measures were evaluated. The instruments varied in relation to the measured construct and measurement properties (validity, reliability and responsiveness). The methodological quality of the studies and the quality of evidence of the patient-reported outcome measures were variable. Among the 13 studies that reported the development of patient-reported outcome measures, most had inadequate methodological quality, and the overall rating was insufficient or inconsistent. The Dysmenorrhea Symptom Interference (DSI) scale was the only identified patient-reported outcome measure that has the potential to be recommended because of its sufficient rating combined with moderate quality of evidence for content validity. Future studies should further evaluate the measurement properties of the existing patient-reported outcome measures, or develop new patient-reported outcome measures following the COSMIN methodology. Not applicable as this is a systematic review. PROSPERO protocol: CRD42021244410. Registration on April 22, 2021.

Computerized Versus Traditional Approaches for Total Knee Arthroplasty: A Quantitative Analysis of Knee Society Score and Western Ontario and McMaster Universities Osteoarthritis Index.

Total knee arthroplasty (TKA) is a common surgery for osteoarthritis, with increasing prevalence expected in the near future. This systematic review and meta-analysis compared the effectiveness of computerized TKA versus traditional TKA, focusing on postoperative outcomes measured by the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) and the Knee Society score (KSS). A search on PubMed and Cochrane databases on November 14, 2023 for retrospective randomized controlled trials (RCTs) yielded data on WOMAC and KSS. The search strategy was predefined, and methodological quality of studies was critically appraised. Two researchers extracted data. Unpaired t-testing assessed the mean monthly changes in KSS and WOMAC for computer-aided versus traditional TKA. Review Manager 5.3 was used for data synthesis and analysis. Out of 729 records, five RCTs enrolling 339 patients were eligible and analyzed using a random effects meta-analysis. The mean monthly ΔKSS score differed significantly between the traditional and computerized groups (11.47 ± 8.76 vs. 9.26 ± 6.05, respectively; p < 0.01). However, the pooled mean difference estimate showed no significant differences (D = 0.20, 95% CI = -0.53 to 0.93, p = 0.59), with high heterogeneity (I2 = 85%, p < 0.001). The mean monthly ΔWOMAC score also differed significantly (-14.18 ± 21.54 vs. -18.43 ± 20.65, respectively; p < 0.05), but again, no significant differences were found in the pooled estimate (D = 0.17, 95% CI = -0.46 to 0.79, p = 0.60), with moderate heterogeneity (I2 = 28%, p = 0.24).There is no significant difference in KSS or WOMAC outcomes between traditional and computerized TKA. The study suggests the need for further research with longer follow-up periods, more timepoints, and a broader range of patient outcome measures to fully evaluate the advantages and disadvantages of each method.

The long-term adherence following the end of Community Treatment Order: A systematic review.

The community treatment order (CTO) is designed to deliver mental healthcare in the community and has been introduced in around 75 jurisdictions worldwide. It constitutes a legal obligation in which individuals with severe mental illness must adhere to out-of-hospital treatment plans. Despite intense criticism and the debated nature of published evidence, it has emerged as a clinical and policy response to frequent hospital readmissions and to enhance adherence in cases where there is refusal of pharmacological treatments. This systematic review outlines findings on CTO long-term adherence, after mandatory outpatient treatment has ended, in studies that include people with psychiatric disorders. Following PRISMA guidelines, we performed a review of published articles from PubMed, PsycINFO, EMBASE, and CINAHL up to January 15, 2023. We included studies that assessed adherence after CTO ends. The study is registered with PROSPERO number CRD42022360879. Six independent studies analyzing the main indicators of long adherence: engagement with services and medication adherence, were included. The average methodological quality of the studies included is fair. Long-term adherence was assessed over a period ranging from 11 to 28 months. Only two studies reported a statistically significant improvement. Regarding the remaining studies, no positive correlation was observed, except for certain subgroup samples, while in one study, medication adherence decreased. Scientific evidence supporting the hypothesis that CTO has a positive role on long-term adherence post-obligation is currently not sufficient. Given the importance of modern recovery-oriented approaches and the coercive nature of compulsory outpatient treatment, it is necessary that future studies ensure the role of CTO in effectively promoting adherence.

A role for curcumin in preventing liver fibrosis in animals: a systematic review and meta-analysis

ObjectiveThis meta-analysis aimed to determine the efficacy of curcumin in preventing liver fibrosis in animal models.MethodsA systematic search was conducted on studies published from establishment to November 2023 in PubMed, Web of Science, Embase, Cochrane Library, and other databases. The methodological quality was assessed using Sycle’s RoB tool. An analysis of sensitivity and subgroups were performed when high heterogeneity was observed. A funnel plot was used to assess publication bias.ResultsThis meta-analysis included 24 studies involving 440 animals with methodological quality scores ranging from 4 to 6. The results demonstrated that curcumin treatment significantly improved Aspartate aminotransferase (AST) [standard mean difference (SMD) = -3.90, 95% confidence interval (CI) (−4.96, −2.83), p &amp;lt; 0.01, I2 = 85.9%], Alanine aminotransferase (ALT)[SMD = − 4.40, 95% CI (−5.40, −3.40), p &amp;lt; 0.01, I2 = 81.2%]. Sensitivity analysis of AST and ALT confirmed the stability and reliability of the results obtained. However, the funnel plot exhibited asymmetry. Subgroup analysis based on species and animal models revealed statistically significant differences among subgroups. Furthermore, curcumin therapy improved fibrosis degree, oxidative stress level, inflammation level, and liver synthesis function in animal models of liver fibrosis.ConclusionCurcumin intervention not only mitigates liver fibrosis but also enhances liver function, while concurrently modulating inflammatory responses and antioxidant capacity in animal models. This result provided a strong basis for further large-scale animal studies as well as clinical trials in humans in the future.Systematic Review Registration:https://www.crd.york.ac.uk/prospero/, identifier CRD42024502671.

Hypoplastic and Congenital Absence of Coronary Arteries and Its Correlation with Clinical Implications of Cardiac Circulation: A Systematic Review and Meta-Analysis

Background: Coronary arteries originate from the first portion of the aorta, emerging from the right and left aortic sinuses. They traverse through the subepicardium and coronary sulcus to supply the myocardium during diastolic function. The objective of this review was to understand how the hypoplasia and agenesis of the coronary arteries are associated with cardiac pathologies. Methods: The databases Medline, Scopus, Web of Science, Google Scholar, CINAHL, and LILACS were researched until January 2024. An assurance tool for anatomical studies (AQUA) was used to evaluate methodological quality. The pooled prevalence was estimated using a random effects model. Results: A total of three studies met the established selection criteria for inclusion in this meta-analysis. The prevalence of coronary artery variants was 3% (CI = 2% to 8%), with a heterogeneity of 77%. The other studies were analyzed descriptively, along with their respective clinical considerations in the presence of the variant. Conclusions: Hypoplasia and the congenital absence of the coronary arteries are often incidental findings and understanding these variants is crucial to prevent misdiagnosis. Additionally, it is essential to exercise caution when considering surgical management for hearts with these variants.

Remodeling and Regenerative Properties of Fully Absorbable Meshes for Abdominal Wall Defect Repair: A Systematic Review and Meta-Analysis of Animal Studies.

Fully absorbable meshes can repair abdominal wall defects and effectively reduce the incidence of complications, but different types of fully absorbable meshes have different remodeling and regeneration effects. In order to investigate and compare the effects of different fully absorbable meshes on remodeling and regeneration in animals and reduce the biological risk of clinical translation, SYRCLE was adopted to evaluate the methodological quality of the included studies, and GRADE and ConQual were used to evaluate the quality of evidence. According to the inclusion and exclusion criteria, a total of 22 studies related to fully absorbable meshes were included in this systematic review. These results showed that fiber-based synthetic materials and fiber-based natural materials exhibited better restorative and regenerative effects indicated by infiltration and neovascularization, when compared with a porcine acellular dermal matrix. In addition, the human acellular dermal matrix was found to have a similar regenerative effect on the host extracellular matrix and scaffold degradation compared to the porcine acellular dermal matrix, porcine intestinal submucosa, and fiber-based natural materials, but it offered higher tensile strength than the other three. The quality of the evidence in this field was found to be poor. The reasons for downgrading were analyzed, and recommendations for future research included more rigor in study design, more transparency in result reporting, more standardization of animal models and follow-up time for better evaluation of the remodeling and regenerative performance of abdominal wall hernia repair meshes, and less biological risk in clinical translation.

Current Research on Matching Trauma-Focused Therapies to Veterans: A Scoping Review.

Trauma-focused (psycho)therapies (TFTs) are often used to treat post-traumatic stress disorder (PTSD) of (military) veterans, including prolonged exposure (PE), cognitive processing therapy (CPT), and eye movement desensitization and reprocessing. However, research thus far has not conclusively determined predictors of TFTs' success in this population. This scoping review's objectives are 1) to explore whether it is possible, based on currently available evidence, to match TFTs to veterans to maximize their outcomes, (2) to identify possible contraindications and adaptations of TFTs for this population, and (3) to identify gaps in the literature to guide future research. Standard scoping review methodology was used. "White" and "gray" literature searches resulted in 4963 unique items identified. Following title and abstract screening and full-text analysis, 187 sources were included in the review. After data extraction, a narrative summary was used to identify common themes, discrepancies between sources, and knowledge gaps. Included publications most often studied CPT and PE rather than eye movement desensitization and reprocessing. These TFTs were at least partly effective with mostly moderate effect sizes. Attrition rates were slightly higher for PE versus CPT. There was variance in the methodological quality of the included studies. The current literature on TFTs to treat PTSD in veterans contains several knowledge gaps, including regarding treatment matching. Future research should examine effectiveness of these treatments using multiple sources of outcomes, longer time periods, combination with other treatment, outcomes outside of PTSD symptoms (such as functioning), and resilience.
