Effect of Bright Light Therapy on Perinatal Depression: A Systematic Review and Meta-Analysis: Effet de la luminothérapie sur la dépression périnatale: une revue systématique et une méta-analyse.

OBJECTIVE: This study represents the inaugural attempt to systematically review and analyse the efficacy of bright light therapy on depression among women experiencing major depressive disorder or depressive symptoms during the perinatal period, encompassing its efficacy on depression scores, remission rates, and response rates. METHODS: We searched 10 databases for randomized controlled trials examining bright light therapy's efficacy on perinatal depression up to January 2024. Data extraction was performed independently by 2 investigators. The Cochrane Handbook guidelines appraised the study quality, and the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach assessed evidence certainty. RESULTS: We incorporated 6 studies, encompassing 151 participants. When contrasted with dim light therapy, bright light therapy did not significantly alter depression scores (standard mean difference = -0.29, 95% confidence interval [CI], -0.62 to 0.04, P = 0.08, I² = 34%) or response rates (risk ratio [RR] = 1.56, 95% CI, 0.98 to 2.49, P = 0.06, I² = 0%) in women experiencing perinatal depression. Conversely, bright light therapy was associated with a substantial increase in remission rates (RR = 2.63, 95% CI, 1.29 to 5.38, P = 0.008, I² = 2%). CONCLUSION: Bright light therapy did not show efficacy in treating perinatal depression in terms of depression scores and response rates. However, regarding the remission rate, bright light did show efficacy compared to control conditions. Due to the limited sample size in the included studies, type II err or may occur. To obtain more conclusive evidence, future studies must employ larger sample sizes.

The reverse Trendelenburg position in proximal ureteral stone management: A systematic review and meta-analysis.

INTRODUCTION: Ureteroscopy lithotripsy (URSL) presents a therapeutic option for patients with proximal ureteral calculi warranting active removal. This systematic review and meta-analysis aimed to assess the efficacy of the reverse Trendelenburg (RT) position during this procedure. MATERIALS: A comprehensive literature search was conducted across PubMed, Embase, and Cochrane databases to identify randomized controlled trials and observational studies comparing RT versus standard positioning (STD) in patients undergoing URSL for proximal ureteral stones. Heterogeneity was measured with the Cochran's Q test, I2 statistics, and prediction intervals (PI). A DerSimonian and Laird random-effects model was utilized for all outcomes. RESULTS: Four studies encompassing 505 patients undergoing URSL were analyzed. Among the studied participants, 293 (58%) underwent RT positioning. Overall, RT was associated with a lower average incidence of stone retropulsion (RR 0.42; 95% CI 0.27-0.65; I2=48%; PI 0.08-2.10) and a higher mean stone-free rate (RR 1.33; 95% CI 1.18-1.49; I2=0%). However, no significant difference between groups was found in the mean rate of overall complications (RR 0.76; 95% CI 0.40-1.43; I2=51%; PI 0.00-520.22) and operative time (MD -0.65; 95% CI -9.58-8.27; I2=94%; PI -111.95-110.65). In those with proximal ureteral stones undergoing RT positioning at only the 20° angle, there was a reduction in stone retropulsion without any measured heterogeneity (RR 0.35; 95% CI 0.23-0.52; I2=0%). CONCLUSION: These findings suggest that RT positioning is effective in improving outcomes for patients with proximal ureteral stones undergoing URSL, and its use should be considered during the procedure.

Association of SGLT2i vs DPP4i With Pneumonia, COVID-19, and Other Adverse Respiratory Events in Patients With Type 2 Diabetes Mellitus: A Systematic Review and Meta-analysis.

OBJECTIVE: Our aim in this study was to systematically assess the association of sodium-glucose cotransporter-2 inhibitors (SGLT2i) vs dipeptidyl peptidase-4 inhibitors (DPP4i) with pneumonia, COVID-19, and adverse respiratory events in patients with type 2 diabetes mellitus (DM). METHODS: PubMed, Embase, and Cochrane Library databases were retrieved to include studies on DM patients receiving SGLT2i (exposure group) or DPP4i (control group). Stata version 15.0 statistical software was used for the meta-analysis. RESULTS: Ten studies were included, all 10 of which were used for the qualitative review and 7 for the meta-analysis. According to the meta-analysis, patients receiving SGLT2i had a lower incidence of pneumonia (odds ratio [OR] 0.62, 95% confidence interval [CI] 0.51 to 0.74) and pneumonia risk (OR 0.63, 95% CI 0.60 to 0.68, p=0.000) compared with those receiving DPP4i. The same situation was seen for mortality for pneumonia (OR 0.49, 95% CI 0.39 to 0.60) and pneumonia mortality risk (OR 0.47, 95% CI 0.42 to 0.51). There was lower mortality due to COVID-19 (OR 0.31, 95% CI 0.28 to 0.34) and a lower hospitalization rate (OR 0.61, 95% CI 0.56 to 0.68, p=0.000) and incidence of mechanical ventilation (OR 0.69, 95% CI 0.58 to 0.83, p=0.000) due to COVID-19 in patients with type 2 DM receiving SGLT2i. Qualitative analysis results show that SGLT2i was associated with a lower incidence of COVID-19, lower risk of obstructive airway disease events, and lower hospitalization rate of health-care-associated pneumonia than DPP4i. CONCLUSION: In patients with type 2 DM, SGLT2i are associated with a lower risk of pneumonia, COVID-19, and mortality than DPP4i.

Ranking Alpha Lipoic Acid and Gamma Linolenic Acid in Terms of Efficacy and Safety in the Management of Adults With Diabetic Peripheral Neuropathy: A Systematic Review and Network Meta-analysis.

OBJECTIVES: Current medications for diabetic neuropathy (DN) recommended by the American Diabetes Association and American Academy of Neurology do not address the pathologic process of denervation among patients with DN, because ancillary treatments, such as reactive oxygen scavengers, may be needed. The purpose of this work was to summarize the available evidence about the efficacy and safety of alpha lipoic acid (ALA) and gamma linolenic acid (GLA) in the management of DN. METHODS: Using the search terms [(alpha lipoic acid or ALA or thioctic acid or thioctacid) or (gamma linolenic acid or GLA)] AND [(diabetes or diabetes mellitus) AND (polyneuropathy or neuropathy or sensorimotor polyneuropathy or radiculopathy)], 11 studies were included in this review and combined meta-analysis. RESULTS: Eight of the 11 articles (73%) reported significant benefit of ALA vs placebo. In the meta-analysis, the Total Symptom Score (TSS) for ALA 600 mg/day (ALA600) was 1.05 points lower (standard mean difference [SMD] -1.05, 95% confidence interval [CI] -2.07 to -0.04, p=0.04, I2=98.18%) compared with control at the end of the study. In the network meta-analysis, ALA600 (SMD -1.68, 95% CI -2.8 to -0.6) and GLA (SMD -2.39, 95% CI -4.3 to -0.5) had significantly lower TSSs compared with placebo. Moreover, GLA had the highest probability of being the best (52.7%) for improving DN symptoms. In all studies, most adverse events include gastrointestinal disturbances. In terms of tolerability, no differences were detected between ALA and control groups. CONCLUSION: ALA and GLA appear to be safe and efficacious biofactors for improvement of DN symptoms.

[Ketamine in antidepressant treatment: a revolution?] / Évolution ou révolution dans le traitement des dépressions avec la kétamine ?

Thirty percent of depressed patients are treatment resistant (TRD) suggesting the need of new therapeutic strategy. Recently, it has been shown that ketamine, an anesthetic agent with dissociative effects, has potent and rapid antidepressant properties. Ketamine is a ionotropic glutamatergic NMDA antagonist that inhibits gabaergic neurons. Its antidepressant effect peaks at 24 h post-treatment. Several meta-analyses of placebo randomized clinical trials emphasized its efficacy. More recently, a meta-analysis showed its efficiency in real-world population of TRD patients. Although there is no clear biological or clinical predictors of response or remission to ketamine, patients with high level of resistance were found to remit less often. Restoring both the optimism bias and the asymmetry in belief updating mediates the antidepressant ketamine's effect. Consistent with predictive bayesian model and terror management theory, this suggests that dissociation induced by ketamine may contribute to its clinical antidepressant action. Although increasing access to ketamine and esketamine is welcome, legitimate concerns have been raised with respect to long-term safety and abuse risk.

Title: Évolution ou révolution dans le traitement des dépressions avec la kétamine ? Abstract: Définie par l'échec d'au moins deux antidépresseurs de mécanismes d'action différents, la dépression résistante est fréquente et concerne 30 % des patients déprimés. Elle justifie le recours à des stratégies thérapeutiques innovantes. Depuis quelques années, on utilise un agent anesthésiant et dissociatif, la kétamine, et ses dérivés, dans le traitement de la dépression résistante. Dans cette brève revue de la littérature, nous rapportons les données attestant de l'efficacité et de l'efficience de la kétamine dans cette indication. Certains patients bénéficient plus que d'autres de la kétamine qui est recommandée pour un niveau modéré de résistance. Même si cela reste débattu, la dissociation pourrait contribuer aux effets bénéfiques de la kétamine.

Prevalence rate of ADHD in France: Review of the literature and results from ChiP-ARD study.

OBJECTIVES: Attention Deficit Hyperactivity Disorder (ADHD) is a frequent neurodevelopmental disorder whose first clinical description was published more than two centuries ago. Prevalence rates have been evaluated in many countries and meta-analyses conducted, but the data collected in France are scarce. METHODS: A review of the literature was conducted by retrieving the references from four electronic databases leading to the selection of four studies in children and four in adults. Meta-analyses of prevalence rates were performed on this published data as well as unpublished results from the ChiP-ARD study (Children and Parents with ADHD and Related Disorders), separately for children and adults. RESULTS: While the quality of most studies is questionable, the prevalence rates are close to those reported in international meta-analytic studies for children (3.68%), but are higher in adults (5.5%). CONCLUSIONS: Well-conducted studies in both general and special populations are needed (e.g., in patients with depression, anxiety, bipolar disorder, developmental disorders including autism spectrum disorder, behavioural or substance abuse, and incarcerated). Nevertheless, healthcare stakeholders can conservatively consider that .8 million children and 1.4 million adults in the metropolitan French general population are likely to have ADHD and suffer from its multiple consequences.

Efficacy and safety of atropine in myopic children: A meta-analysis of randomized controlled trials.

PURPOSE: To evaluate the safety and efficacy of atropine for childhood myopia and further explore the optimal concentration of atropine, so as to provide more reference for clinical application. METHODS: PubMed, Embase, Cochrane Library and ClinicalTrials.gov were comprehensively searched for randomized controlled trials (RCTs) up to October 14, 2021. The efficacy outcomes were progression of spherical equivalent (SE) and axial length (AL). The safety outcomes included accommodation amplitude, pupil size and adverse effects. The meta-analysis was performed using Review Manager 5.3. RESULTS: Eighteen RCTs involving 3002 eyes were included. The results showed that at 6-36 months of treatment, atropine was effective in slowing the progression of myopia in children. At 12 months, the WMD of SE and AL of low-dose atropine was 0.25 diopters (D) and 0.1 millimeter (mm), moderate-dose atropine was 0.44 D and 0.16mm, high-dose atropine was 1.21 D and 0.82mm, respectively, compared with the control group. Similarly, at 24 months, low-dose atropine was 0.22 D and 0.14mm, moderate-dose atropine was 0.60 D, high-dose atropine was 0.66 D and 0.24mm, respectively. Interestingly, we also found that there was no significant difference in the effects of low-dose atropine on accommodation amplitude and photopic pupil size compared with the control group, and the rate of photophobia, allergy, blurred vision and other side effects was similar between the low-dose atropine group and the control group. In addition, atropine appears to be more effective in myopic children in China than in other countries. CONCLUSIONS: Atropine in various concentrations can effectively slow myopia progression in children, and its effect is dose-dependent, while low-dose atropine (0.01% atropine) appears to be safer.

Comparison of Efficacy and Safety of Commercially Available Fixed-Ratio Combinations of Insulin Degludec/Liraglutide and Insulin Glargine/Lixisenatide: A Network Meta-analysis.

OBJECTIVES: Our aim in this study was to compare the efficacy and safety of commercially available fixed-ratio combinations (FRCs) of glucagon-like peptide-1 receptor agonists (GLP-1RAs) and basal insulins by a network meta-analysis of randomized controlled trials (RCTs) of people with type 2 diabetes. METHODS: We present a systematic review and network meta-analyses of RCTs of individuals with type 2 diabetes randomized to FRCs or to their components for ≥24 weeks. All reports were obtained from PubMed or ClinicalTrials.gov up to February 28, 2022. The primary outcome was glycated hemoglobin (A1C) level attained. Secondary outcomes included fasting plasma glucose, change in body weight, and incident hypoglycemia. Treatment effects were estimated as mean difference (MD) and standard error (SE), or as odds ratio (OR) with 95% confidence interval (CI) using the fixed combination of insulin glargine 100 IU/mL and lixisenatide (iGlarLixi) as reference. RESULTS: We included 29 RCTs from among the 1,404 articles identified. No direct comparisons between FRCs were found. After excluding some insulin-capped trials to reach model consistency, both FRCs were more efficacious regarding A1C than their components, but no difference between FRCs was found (MD, -0.10%; SE, 0.10%). The effect of the fixed combination of insulin degludec and liraglutide (IDegLira) (MD, -0.47 mmol/L; SE, 0.24 mmol/L) and basal insulins was similar to that of iGlarLixi (reference) on fasting glucose, whereas GLP-1RAs had lower efficacy than iGlarLixi. Weight gain was lower with GLP-1RAs and IDegLira (MD, -0.72 kg; SE, 0.32 kg) than with iGlarLixi (reference) and higher with basal insulins. Incident hypoglycemia (based on different definitions) was least frequent with GLP-1RAs, followed by IDegLira (OR, 0.78; 95% CI, 0.39 to 1.57), iGlarLixi (reference), and basal insulins. CONCLUSIONS: For A1C, both FRCs were more efficacious over their individual components, with similar efficacies of the 2 FRCs.

Human amniotic membrane graft for refractory macular hole: A single-arm meta-analysis and systematic review.

PURPOSE: The treatment of refractory macular holes is controversial, with human amniotic membrane grafts emerging recently as an attractive option. We performed a meta-analysis and systematic review in this paper to assess the results of human amniotic membrane (hAM) in the treatment of refractory macular hole (MH). METHODS: We searched the Cochrane Database of Systematic Reviews, Web of Science, PubMed, Embase, China National Knowledge Infrastructure databases, VIP database, Wanfang Data Knowledge Service Platform, Sinomed, Chinese Clinical Trial Registry, and Clinical Trials.gov. Studies reporting hAM for the treatment of refractory MH were included. The outcomes are MH closure rate, visual acuity (VA) improvement rate, and graft dislocation/contracture rate. RESULTS: A total of 8 studies on 103 eyes were included, all of which had undergone failed vitrectomy and internal limiting membrane (ILM) peeling. In all studies, the VA improvement rate was 66% (95%CI: 45 to 84%), the MH closure rate was 94% (95%CI: 84 to 100%) and the hAM graft dislocation/contracture rate was 6% (95%CI: 0 to 15%). In the studies using cryopreserved hAM grafts, the MH closure rate was 99% (95%CI: 94 to 100%) and the hAM graft dislocation/contracture rate was 3% (0%, 10%). The VA improvement rates were 94% (95%CI: 79 to 100%) in the retinal detachment subgroup, 37% (95%CI: 20 to 56%) in the pathologic myopia subgroup, and 62% (95%CI: 14 to 100%) in the idiopathic MH subgroup. CONCLUSION: Human amniotic membrane in the treatment of refractory MH results in visual improvement. It has a high macular hole closure rate and low dislocation/contracture rate. Cryopreserved hAM grafts might have better outcomes than dehydrated grafts.

Intervention Effect of Pender's Model on Mental Health of Patients With Diabetes Mellitus: A Meta-analysis.

OBJECTIVE: Our aim in this study was to better understand the intervention effect of Pender's model on the physical and mental health of patients with diabetes mellitus. METHODS: According to the principle of Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, various databases, including CNKI, Wanfang Data, SinoMed, VIP, Web of Science, Cochrane, PubMed and ScienceDirect, were searched to collect and select relevant reports for the implementation of a meta-analysis. RESULTS: Ten randomized controlled trials in 6 foreign reports and 4 Chinese reports were included in this study. A total of 863 participants were involved, including 439 in the experimental group and 424 in the control group. Results of the meta-analysis show that Pender's model has a good intervention effect on the health knowledge (Z=3.371, p<0.050), self-management behaviour (Z=3.781, p<0.050) and psychological function (Z=2.902, p<0.050) of patients with diabetes mellitus as compared to the control group. The subgroup analysis showed that the intervention effect on self-management behaviour would not be affected by the measurement tool used (Z=3.295, p=0.001). CONCLUSIONS: Pender's model showed a good intervention effect on the health knowledge, self-management behaviour and psychological function of patients with diabetes mellitus.

Preoperative ultra-hypofractionation radiotherapy in extremity/trunk wall soft tissue sarcoma - A meta-analysis of prospective studies.

PURPOSE: The neoadjuvant radiotherapy is now standard treatment in soft tissue sarcoma. Using ultra-hypofractionation radiotherapy shorten the treatment time. In the era of COVID pandemic, using less fraction to treat patient is an urgent need. Thus, we aim to use meta-analysis to investigate the clinical efficacy of preoperative stereotactic body radiotherapy. MATERIAL AND METHODS: PRISMA guideline was used in this study. PubMed, Cochrane and Embase were used. We include only prospective study. The main endpoint was set as wound complication rate. Other endpoints include R0 resection rate, overall survival, local control, and distant metastasis free survival. RESULTS: Seven studies were included. The pooled wound complication rate is 0.30 (95% CI=0.26-0.35). The pooled R0 resection rate is 0.87(95%CI: 0.74-0.94). The pooled 2-year overall survival is 0.86 (95%CI: 0.72-0.94). The pooled 2-year local control rate is 0.96(95%CI: 0.89-0.99). The pooled 2-year distant metastasis free survival is 0.60 (95%CI=0.50-0.70). CONCLUSION: Neoadjuvant ultra-hypofractionation radiotherapy in soft tissue sarcoma is a feasible and well tolerable treatment.

Effectiveness of therapeutic massage for improving motor symptoms in Parkinson's disease: A systematic review and meta-analysis.

Background: Parkinson's disease (PD) causes movement disorders [called motor symptoms (MS)], and motor dysfunction poses a great barrier to the quality of life. Although pharmacological therapy like levodopa can relieve the symptoms, it can also cause complications, such as psychosis, nausea, and dyskinesia. A therapy with more minor side effects is needed for PD. Therapeutic massages are the most commonly used forms of complementary and alternative medicine (CAM), but no systematic review and meta-analysis have focused on the efficacy of massage on PD. Objective: To evaluate the quality of evidence and efficacy of therapeutic massage for improving MS in PD. Methods: We independently searched four electronic databases, including Chinese National Knowledge Infrastructure (CNKI), MEDLINE/PubMed, Embase, and Cochrane Library, for randomized controlled trials (RCTs) about therapeutic massage and other available manual therapies improving MS in PD from January 1, 2012, to December 31, 2021 (recent 10 years). The main outcome measures were total effectiveness and the Unified Parkinson's Disease Rating Scale (UPDRS), including UPDRS total, II, and III. For the statistical analysis, the risk ratio, standard mean difference, and 95% confidence interval (CI) were used to calculate effect sizes between groups. To determine heterogeneity, statistical index I 2 was used. Results: A total of 363 PD participants in seven RCTs and one randomized pilot-control study were included in this meta-analysis. The total effectiveness showed that therapeutic massage was more effective than the intervention of the control group for improving MS [ratio risk (RR): 1.33, 95% CI (1.14-1.55), p = 0.0002]. The UPDRS-III scores showed that massage improves motor function more than the control group [SMD = -0.46, 95% CI (-0.67, -0.24), p < 0.00001]. But we found that massage performed no better than the control group in improving daily life activities [SMD = -0.15, 95% CI (-0.40, 0.10), p = 0.23]. Conclusion: Therapeutic massage was effective in improving MS in PD. It is suggested to be an appropriate form of CAM in treating PD.

Dose-Dependent Effect of Intake of Fermented Dairy Foods on the Risk of Diabetes: Results From a Meta-analysis.

Diabetes mellitus (DM) is one of the largest epidemics the world has faced. Given the morbidity and mortality burden of DM, it is important to identify modifiable factors that affect the natural course of the disease. We carried out this meta-analysis of published studies to estimate the overall DM risk of intake of fermented dairy foods, and to reveal the dose-dependent effect on DM risk. We searched the PubMed, Embase and China National Knowledge Infrastructure databases for all articles published between the years 1980 to 2020 on the association between fermented dairy foods intake and DM risk. Fifteen studies met the inclusion criteria for our study, including a total of 485,992 participants and 20,207 incidences of diabetes. Overall, statistical evidence of significantly decreased diabetes risk was found to be associated with higher intake of fermented dairy foods (odds ratio [OR], 0.925; 95% confidence interval [CI], 0.856 to 0.999). In a subgroup analysis, higher yogurt consumption was significantly associated with decreased DM risk (OR, 0.828; 95% CI, 0.729 to 0.941). Our meta-analysis shows that intake of fermented dairy foods is associated with decreased DM risk, and the effect may be dose-dependent.

Difference in the effect of orthokeratology on slowing teen myopia with different years of follow-up.

PURPOSE: To compare the effects of orthokeratology (OK) for early childhood myopia control and to contrast with clinical trial data published by various investigators. METHODS: The researchers studied papers in Pubmed, Embase, Clinicalkey and CNKI published before October 31, 2021, identified by searching for RCT (Randomized controlled trials) and cohort studies on the treatment of early childhood myopia with orthokeratology. The researchers extracted the mean deviation for axial elongation at each year of follow-up between the orthokeratology groups and control groups (myopic spectacles) and analyzed the results with stata 12.0 software. RESULTS: The meta-analysis included 4 RCTs and 9 cohort studies with 744 samples (OK group 362, control group 382), aged 6 to 17 years. There was evidence of heterogeneity (I2>50%) on axial elongation in the included data. At 1 year, 2 years, 3 years, 4 years, 5 years and 7 years of follow-up, the axial elongation figures were -0.15mm (95% [CI] (confidence interval), -0.16 to -0.14) in all studies, -0.28mm (95% [CI], -0.33 to -0.23) in all studies, -0.36mm (95% [CI], -0.45 to -0.27) in one study, -0.42mm (95% [CI], -0.52 to -0.32) in one study, -0.42mm (95% [CI], -0.77 to -0.07) in one study, -0.44mm (95% [CI], -0.65 to -0.23) in one study. The heterogeneity disappeared after dividing subgroups according to the length of follow-up. CONCLUSION: Compared with the control group, the first two years of orthokeratology can control axial elongation in children and effectively delay the development of myopia. However, this effect was not obvious after 2 years. It is recommended to prescribe orthokeratology for two years to obtain the best effect. The length of therapy must be taken into account when studying the effects of orthokeratology.

Prevalence of methylmalonic acidemia among newborns and the clinical-suspected population: a meta-analyse.

IMPORTANCE: Knowing the scale of rare inborn errors is important for screening and resource allocation. Evidence on the prevalence of methylmalonic acidemia (MMA) among newborns and the clinical-suspected population from large-scale screening programs needs to be systematically synthesized. OBJECTIVE: To estimate the worldwide prevalence of MMA for newborns and the clinical-suspected population and explore the differences in different regions, periods, and diagnostic technologies. DATA SOURCES: MEDLINE, Embase, CRD, Cochrane Library, Scopus, CINAHL, and PROSPERO. Study Selection: All studies reporting the epidemiology characteristics of MMA were selected. DATA EXTRACTION AND SYNTHESIS: Characteristics of study, subjects, and epidemiology were extracted, random-effect models were used for meta-analyses. MAIN OUTCOME AND MEASURE: Pooled prevalence of MMA. RESULTS: This study included 111 studies. The pooled prevalence of MMA worldwide was 1.14 per 100,000 newborns (1516/190,229,777 newborns, 95% CI: 0.99-1.29) and 652.11 per 100,000 clinical-suspected patients (1360/4,805,665 clinical-suspected individuals, CI: 544.14-760.07). Asia and Africa got a higher pooled prevalence of MMA. The prevalence of MMA in newborns increased through the years, while that in the clinical-suspected population decreased. Collecting blood ≥ 72 h after birth had a higher pooled prevalence of MMA than collecting during 24 h-72 h after birth. The combining-use of MS/MS and GC/MS had a higher pooled prevalence than the single-use of MS/MS or GC/MS. Prevalence of cbl C, mut, cbl B, cbl A, isolated MMA, combined MMA and homocystinuria, vitamin B12-responsive MMA was synthesized. CONCLUSIONS AND RELEVANCE: Prevalence of MMA among newborns was extremely low, but considerably high in the clinical-suspected population, indicating the need for more efficient newborn screening strategies and closer monitoring of the high-risk population for the early signs of MMA. Asia and Africa should attach importance to the high prevalence of MMA. Further diagnostic tests were recommended for the combining-use vs single-use of MS/MS and GC/MS and for collecting blood after 72 h vs during 24-72 h after birth.

Clinical efficacy of the enzyme replacement therapy in patients with late-onset Pompe disease: a systematic review and a meta-analysis.

In patients with late-onset Pompe disease (LOPD), the efficacy of the enzyme replacement therapy (ERT) with recombinant human alpha-glucosidase (rhGAA) is difficult to evaluate, due to the clinical heterogeneity and the small sample sizes in published studies. Therefore, we conduct a systematic literature review and meta-analysis of the literature to evaluate the efficacy of ERT in LOPD patients considering the walking distance, respiratory function and muscle strength. Particularly, six-minute walk test (6MWT), forced vital capacity (FVC), medical research council (MRC) grading, quantitative muscle testing (QMT), and quick motor function test (QMFT) were outcomes of interest. Overall, 619 studies were identified in PubMed, EMBASE and by manual search on July 18th, 2020. After an initial assessment, 16 studies were included in the meta-analysis, containing clinical data from 589 patients with LOPD. For the 6MWT, 419 patients were analyzed. Walking distance improved on average, 32.2 m greater during the observed period (p = 0.0003), compared to the distance at the baseline. The meta-analysis did not show any improvement in FVC and only a tendency towards better muscle strength after treatment with ERT, but the difference was not statistically significant. In conclusion, the available data showed that ERT has a significant beneficial efficacy in the improvement of walking distance in LOPD patients and a non-significant improvement of muscle strength. No improvement in respiratory capacity was found. More prospective and controlled trials are needed to demonstrate a clear clinical benefit of ERT.

Functional analysis of co-expression networks of zebrafish ace2 reveals enrichment of pathways associated with development and disease.

Human Angiotensin I Converting Enzyme 2 (ACE2) plays an essential role in blood pressure regulation and SARS-CoV-2 entry. ACE2 has a highly conserved, one-to-one ortholog (ace2) in zebrafish, which is an important model for human diseases. However, the zebrafish ace2 expression profile has not yet been studied during early development, between genders, across different genotypes, or in disease. Moreover, a network-based meta-analysis for the extraction of functionally enriched pathways associated with differential ace2 expression is lacking in the literature. Herein, we first identified significant development-, tissue-, genotype-, and gender-specific modulations in ace2 expression via meta-analysis of zebrafish Affymetrix transcriptomics datasets (ndatasets = 107); and the correlation analysis of ace2 meta-differential expression profile revealed distinct positively and negatively correlated local functionally enriched gene networks. Moreover, we demonstrated that ace2 expression was significantly modulated under different physiological and pathological conditions related to development, tissue, gender, diet, infection, and inflammation using additional RNA-seq datasets. Our findings implicate a novel translational role for zebrafish ace2 in organ differentiation and pathologies observed in the intestines and liver.

Evaluation of the diagnostic accuracy of current biomarkers in heart failure with preserved ejection fraction: A systematic review and meta-analysis.

BACKGROUND: A number of circulating biomarkers are currently utilized for the diagnosis of chronic heart failure with preserved ejection fraction (HFpEF). However, due to HFpEF heterogeneity, the accuracy of these biomarkers remains unclear. AIMS: This study aimed to systematically determine the diagnostic accuracy of currently available biomarkers for chronic HFpEF. METHODS: PubMed, Web of Science, MEDLINE and SCOPUS databases were searched systematically to identify studies assessing the diagnostic accuracy of biomarkers of chronic HFpEF with left ventricular ejection fraction (LVEF) ≥50%. All included studies were independently assessed for quality and relevant information was extracted. Random-effects models were used to estimate the pooled diagnostic accuracy of HFpEF biomarkers. RESULTS: The search identified 6145 studies, of which 19 were included. Four biomarkers were available for meta-analysis. The pooled sensitivity of B-type natriuretic peptide (BNP) (0.787, 95% confidence interval [CI] 0.719-0.842) was higher than that of N-terminal pro-BNP (NT-proBNP) (0.696, 95% CI 0.599-0.779) in chronic HFpEF diagnosis. However, NT-proBNP showed improved specificity (0.882, 95% CI 0.778-0.941) compared to BNP (\0.796, 95% CI 0.672-0.882). Galectin-3 (Gal-3) exhibited a reliable diagnostic adequacy for HFpEF (sensitivity 0.760, 95% CI 0.631-0.855; specificity 0.803, 95% CI 0.667-0.893). However, suppression of tumorigenesis-2 (ST2) displayed limited diagnostic performance for chronic HFpEF diagnosis (sensitivity 0.636, 95% CI 0.465-0.779; specificity 0.595, 95% CI 0.427-0.743). CONCLUSION: NT-proBNP and BNP appear to be the most reliable biomarkers in chronic HFpEF with NT-proBNP showing higher specificity and BNP showing higher sensitivity. Although Gal-3 appears more reliable than ST2 in HFpEF diagnosis, the conclusions are limited as only three studies were included in this meta-analysis.
