Meta-Analysis Review
BACKGROUND
The oXiris is a novel filter for continuous renal replacement therapy (CRRT) featuring an adsorption coating to adsorb endotoxins and remove inflammatory mediators. Given that no consensus has been reached on its potential benefits in treating sepsis, a meta-analysis was conducted to assess its impact on the clinical outcomes of this patient population.
METHODS
Eleven databases were retrieved to find relevant observational studies and randomized controlled trials. The Newcastle-Ottawa Scale and the Cochrane Risk of Bias Tool were used to assess the quality of the included studies. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) process was employed to assess the certainty of evidence. The 28-day mortality was the primary outcome. Secondary outcomes were 7-, 14-, and 90-day mortality, length of intensive care unit (ICU) and hospital stay, ICU and hospital mortality, norepinephrine (NE) dose, interleukin-6 (IL-6) and lactate levels, and Sequential Organ Failure Assessment (SOFA) score.
RESULTS
The meta-analysis, pooling data from 14 studies, involving 695 patients, showed significant reductions in 28-day mortality [odds ratio (OR) 0.53; 95% confidence interval (CI) 0.36-0.77, p = 0.001] and length of ICU stay [weighted mean difference (WMD) - 1.91; 95% CI - 2.56 to - 1.26, p < 0.001)] in patients with sepsis using the oXiris filter compared to other filters. Besides, the SOFA score, NE dose, IL-6 and lactate levels, and 7- and 14-day mortalities were lower in the oXiris group. However, the 90-day mortality, ICU and hospital mortality, and length of hospital stay were comparable. The quality assessment of the ten observational studies indicated intermediate to high quality (average Newcastle-Ottawa score: 7.8). However, all four randomized controlled trials (RCTs) had an unclear risk of bias. The evidence for all outcomes had a low or very low level of certainty because the original study design was mainly observational studies and the RCTs included had an unclear risk of bias and a small sample size.
CONCLUSION
The treatment with the oXiris filter during CRRT in sepsis patients may be associated with lower 28-, 7-, and 14-day mortalities, lactate levels, SOFA score, NE dose, and shorter length of ICU stay. However, due to the low or very low quality of evidence, the effectiveness of oXiris filters was still uncertain. Besides, no significant difference was observed for the 90-day mortality, ICU and hospital mortality, and length of hospital stay.

Review
AIM
Skin-to-skin contact immediately after birth is recognised as an evidence-based best practice and an acknowledged contributor to improved short- and long-term health outcomes including decreased infant mortality. However, the implementation and definition of skin-to-skin contact is inconsistent in both practice and research studies. This project utilised the World Health Organization guideline process to clarify best practice and improve the consistency of application.
METHODS
The rigorous guideline development process combines a systematic review with acumen and judgement of experts with a wide range of credentials and experience.
RESULTS
The developed guideline received a strong recommendation from the Expert Panel. The result concluded that there was a high level of confidence in the evidence and that the practice is not resource intensive. Research gaps were identified and areas for continued work were delineated.
CONCLUSION
The World Health Organization guideline development process reached the conclusion immediate, continuous, uninterrupted skin-to-skin contact should be the standard of care for all mothers and all babies (from 1000 g with experienced staff if assistance is needed), after all modes of birth. Delaying non-essential routine care in favour of uninterrupted skin-to-skin contact after birth has been shown to be safe and allows for the progression of newborns through their instinctive behaviours.

Comparative Study Meta-Analysis
IMPORTANCE
There are ongoing concerns about the benefits of intensive vs standard blood pressure (BP) treatment among adults with orthostatic hypotension or standing hypotension.
OBJECTIVE
To determine the effect of a lower BP treatment goal or active therapy vs a standard BP treatment goal or placebo on cardiovascular disease (CVD) or all-cause mortality in strata of baseline orthostatic hypotension or baseline standing hypotension.
DATA SOURCES
Individual participant data meta-analysis based on a systematic review of MEDLINE, EMBASE, and CENTRAL databases through May 13, 2022.
STUDY SELECTION
Randomized trials of BP pharmacologic treatment (more intensive BP goal or active agent) with orthostatic hypotension assessments.
DATA EXTRACTION AND SYNTHESIS
Individual participant data meta-analysis extracted following PRISMA guidelines. Effects were determined using Cox proportional hazard models using a single-stage approach.
MAIN OUTCOMES AND MEASURES
Main outcomes were CVD or all-cause mortality. Orthostatic hypotension was defined as a decrease in systolic BP of at least 20 mm Hg and/or diastolic BP of at least 10 mm Hg after changing position from sitting to standing. Standing hypotension was defined as a standing systolic BP of 110 mm Hg or less or standing diastolic BP of 60 mm Hg or less.
RESULTS
The 9 trials included 29 235 participants followed up for a median of 4 years (mean age, 69.0 [SD, 10.9] years; 48% women). There were 9% with orthostatic hypotension and 5% with standing hypotension at baseline. More intensive BP treatment or active therapy lowered risk of CVD or all-cause mortality among those without baseline orthostatic hypotension (hazard ratio [HR], 0.81; 95% CI, 0.76-0.86) similarly to those with baseline orthostatic hypotension (HR, 0.83; 95% CI, 0.70-1.00; P = .68 for interaction of treatment with baseline orthostatic hypotension). More intensive BP treatment or active therapy lowered risk of CVD or all-cause mortality among those without baseline standing hypotension (HR, 0.80; 95% CI, 0.75-0.85), and nonsignificantly among those with baseline standing hypotension (HR, 0.94; 95% CI, 0.75-1.18). Effects did not differ by baseline standing hypotension (P = .16 for interaction of treatment with baseline standing hypotension).
CONCLUSIONS AND RELEVANCE
In this population of hypertension trial participants, intensive therapy reduced risk of CVD or all-cause mortality regardless of orthostatic hypotension without evidence for different effects among those with standing hypotension.

Effectiveness of Fludrocortisone Plus Hydrocortisone versus Hydrocortisone Alone in Septic Shock: A Systematic Review and Network Meta-Analysis of Randomized Controlled Trials.
The use of hydrocortisone in adult patients with septic shock is controversial, and the effectiveness of adding fludrocortisone to hydrocortisone remains uncertain. To assess the comparative effectiveness and safety of fludrocortisone plus hydrocortisone, hydrocortisone alone, and placebo or usual care in adults with septic shock. A systematic review and a Bayesian network meta-analysis of peer-reviewed randomized trials were conducted. The primary outcome was all-cause mortality at last follow-up. Treatment effects are presented as relative risks (RRs) with 95% credible intervals (CrIs). Placebo or usual care was the reference treatment. Among 7,553 references, we included 17 trials (7,688 patients). All-cause mortality at last follow-up was lowest with fludrocortisone plus hydrocortisone (RR, 0.85; 95% CrI, 0.72-0.99; 98.3% probability of superiority, moderate-certainty evidence), followed by hydrocortisone alone (RR, 0.97; 95% CrI, 0.87-1.07; 73.1% probability of superiority, low-certainty evidence). The comparison of fludrocortisone plus hydrocortisone versus hydrocortisone alone was based primarily on indirect evidence (only two trials with direct evidence). Fludrocortisone plus hydrocortisone was associated with a 12% lower risk of all-cause mortality compared with hydrocortisone alone (RR, 0.88; 95% CrI, 0.74-1.03; 94.2% probability of superiority, moderate-certainty evidence). In adult patients with septic shock, fludrocortisone plus hydrocortisone was associated with lower risk of all-cause mortality at last follow-up than placebo and hydrocortisone alone. The scarcity of head-to-head trials comparing fludrocortisone plus hydrocortisone versus hydrocortisone alone led our network meta-analysis to rely primarily on indirect evidence for this comparison. Although we undertook several sensitivity analyses and assessments, these findings should be considered while also acknowledging the heterogeneity of included trials.

Meta-Analysis
BACKGROUND
Standalone nucleic acid amplification tests (NAATs) are frequently used to diagnose Clostridioides difficile infections (CDI), although they may be unable to distinguish colonization from disease. A 2-stage algorithm pairing NAATs with toxin immunoassays (Toxin) may improve specificity. We evaluated clinical outcomes of patients who were NAAT+/Toxin+ versus NAAT+/Toxin- and treated versus untreated NAAT+/Toxin- cases through systematic review and meta-analysis.
METHODS
We searched EMBASE and MEDLINE from inception to April 1, 2023 for articles comparing CDI outcomes among symptomatic patients tested by NAAT and Toxin tests. The risk differences (RD) of all-cause mortality and CDI recurrence were computed by random effects meta-analysis between patients who were NAAT+/Toxin+ and NAAT+/Toxin-, as well as between patients who were NAAT+/Toxin- and treated or untreated.
RESULTS
Twenty-six observational studies comprising 12 737 patients were included. The 30-day all-cause mortality was not significantly different between those who were NAAT+/Toxin+ (8.4%) and NAAT+/Toxin- (6.7%) (RD = 0.41%, 95% confidence interval [CI] = -.67, 1.49). Recurrence at 60 days was significantly higher among patients who were NAAT+/Toxin+ (19.8%) versus NAAT+/Toxin- (11.0%) (RD = 7.65%, 95% CI = 4.60, 10.71). Among treated compared to untreated NAAT+/Toxin- cases, the all-cause 30-day mortalities were 5.0% and 12.7%, respectively (RD = -7.45%, 95% CI = -12.29, -2.60), but 60-day recurrence was not significantly different (11.6% vs 7.0%, respectively; RD = 5.25%, 95% CI -1.71, 12.22).
CONCLUSIONS
Treatment of patients who were NAAT+/Toxin- was associated with reduced all-cause mortality but not recurrence. Although subject to the inherent limitations of observational studies, these results suggest that some patients who are NAAT+/Toxin- may benefit from treatment.

Meta-Analysis
Pregnant women are one of the endangered groups who need special attention in the COVID-19 epidemic. We conducted a systematic review and summarised the studies that reported adverse pregnancy outcomes in pregnant women with COVID-19 infection. A literature search was performed in PubMed and Scopus up to 1 September 2022, for retrieving original articles published in the English language assessing the association between COVID-19 infection and adverse pregnancy outcomes. Finally, in this review study, of 1790 articles obtained in the initial search, 141 eligible studies including 1,843,278 pregnant women were reviewed. We also performed a meta-analysis of a total of 74 cohort and case-control studies. In this meta-analysis, both fixed and random effect models were used. Publication bias was also assessed by Egger's test and the trim and fill method was conducted in case of a significant result, to adjust the bias. The result of the meta-analysis showed that the pooled prevalence of preterm delivery, maternal mortality, NICU admission and neonatal death in the group with COVID-19 infection was significantly more than those without COVID-19 infection (<.01). A meta-regression was conducted using the income level of countries. COVID-19 infection during pregnancy may cause adverse pregnancy outcomes including of preterm delivery, maternal mortality, NICU admission and neonatal death. Pregnancy loss and SARS-CoV2 positive neonates in Lower middle income are higher than in High income. Vertical transmission from mother to foetus may occur, but its immediate and long-term effects on the newborn are unclear.

Meta-Analysis Review
STATEMENT OF PROBLEM
When restoring endodontically treated teeth, a post system is indicated to retain a core. Clinicians can choose from different post materials and types. However, the literature is inconclusive on the long-term clinical performance of available post systems.
PURPOSE
The purpose of this systematic review and meta-analysis was to analyze the survival and failure rates of endodontically treated teeth restored either with glass-fiber-reinforced or metal posts.
MATERIAL AND METHODS
The research question was formulated by following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines by using the Population, Intervention, Comparison, Outcome, Study Type (PICOS) tool. Medline (PubMed), Embase, and Scopus searches complemented by manual search were performed for randomized controlled clinical trials with a follow-up of at least 2 years. Two independent authors performed screening and data extraction of the articles. Meta-analyses were performed with the RevMan software program. Homogeneity was checked by using chi and I tests, and random-effects meta-analyses were applied. Odds ratio and 95% confidence interval were calculated (α=.05). The publication bias was evaluated by using funnel plots and the Begg and Egger tests.
RESULTS
A total of 184 studies were retrieved through the electronic searches, and an additional 4 through the hand search. After title- and abstract-level exclusion, 23 studies remained for full-text analyses, of which 7 were selected for data extraction. Meta-analyses revealed an overall survival rate of 92.8% for endodontically treated teeth restored with glass-fiber-reinforced posts compared with 78.1% of those restored with metal posts. No statistically significant difference (P>.05) was found in the survival, success, or failure rates.
CONCLUSIONS
No statistically significant differences were found between the survival and failure rates of endodontically treated teeth restored either with glass-fiber-reinforced or metal posts. The overall survival rate was 92.8% for glass fiber posts and 78.1% for metal posts. Both are reliable materials when a significant amount of coronal tooth structure is missing and treatment with a post is indicated.

Meta-Analysis
OBJECTIVE
To synthesize the pooled mortality risk estimate and determine whether cognitive frailty is a predictor of mortality.
DESIGN
A systematic review and meta-analysis.
SETTING AND PARTICIPANTS
The participants were community-dwelling older adults aged ≥60 years.
METHODS
PubMed, Web of Science, Embase, CINAHL, and the Cochrane Library databases were systematically searched. Two researchers independently screened potentially eligible literature, evaluated the quality of the included studies, and then extracted the data. We used STATA, version 15.0 to perform the all data.
RESULTS
Nineteen studies were included. The association between cognitive frailty and a higher risk of death was statistically significant [hazard ratio (HR), 2.01; 95% CI, 1.84-2.19; P < .001]. The outcomes indicated that cognitive frailty was a critical risk factor for predicting mortality (OR, 4.82; 95% CI, 1.59-14.57; P < .01). Based on different models of cognitive frailty, the results of subgroup analyses revealed that the risk of mortality was the highest in the Frail + mild cognitive impairment group (HR, 2.35; 95% CI, 2.05-2.70; P < .001). The subgroup analyses by region demonstrated that mortality risk was lowest in the European group (HR, 1.63; 95% CI, 1.4-1.87; P < .001).
CONCLUSIONS AND IMPLICATIONS
This study quantitatively portrays the pooled mortality risk estimate of cognitive frailty. The results suggest that in older adults, cognitive frailty can be a predictor of mortality. The findings could alert health care providers to pay more attention to cognitive frailty.

Activated phosphoinositide 3-kinase delta syndrome (APDS) is a rare genetic disorder that presents clinically as a primary immunodeficiency. Clinical presentation of APDS includes severe, recurrent infections, lymphoproliferation, lymphoma, and other cancers, autoimmunity and enteropathy. Autosomal dominant variants in two independent genes have been demonstrated to cause APDS. Pathogenic variants in PIK3CD and PIK3R1, both of which encode components of the PI3-kinase, have been identified in subjects with APDS. APDS1 is caused by gain of function variants in the PIK3CD gene, while loss of function variants in PIK3R1 have been reported to cause APDS2. We conducted a review of the medical literature and identified 256 individuals who had a molecular diagnosis for APDS as well as age at last report; 193 individuals with APDS1 and 63 with APDS2. Despite available treatments, survival for individuals with APDS appears to be shortened from the average lifespan. A Kaplan-Meier survival analysis for APDS showed the conditional survival rate at the age of 20 years was 87%, age of 30 years was 74%, and ages of 40 and 50 years were 68%. Review of causes of death showed that the most common cause of death was lymphoma, followed by complications from HSCT. The overall mortality rate for HSCT in APDS1 and APDS2 cases was 15.6%, while the mortality rate for lymphoma was 47.6%. This survival and mortality data illustrate that new treatments are needed to mitigate the risk of death from lymphoma and other cancers as well as infection. These analyses based on real-world evidence gathered from the medical literature comprise the largest study of survival and mortality for APDS to date.

Meta-Analysis
OBJECTIVES
To determine the prognostic factors of dermatomyositis with anti-melanoma differentiation-associated gene 5 (MDA5) antibody, a rare disease and often complicated by life-threatening, rapidly progressive interstitial lung disease.
METHODS
Herein, we searched the Medline, Embase, and Cochrane Library databases and extracted studies published before August 23, 2022. Pooled analysis of hazard ratios (HRs) or odds ratios was used to identify prognostic factors for mortality among patients with anti-MDA5 antibody-positive dermatomyositis (MDA5+ DM).
RESULTS
Twenty-nine cohorts with 2,645 patients were included in this meta-analysis. Factors related to poor prognosis included old age (HR 1.54, 95% confidence interval (CI) 1.41-1.69, p < 0.01), male sex (HR 2.07, 95% CI 1.34-3.18, p < 0.01), rapidly progressive interstitial lung disease (RP-ILD) (HR 9.34, 95% CI 6.39-13.6, p < 0.01), high levels of ferritin (HR 1.05, 95% CI 1.01-1.08, p < 0.01), C-reactive protein (CRP) (HR 1.12, 95% CI 1.06-1.19, p < 0.01), creatine kinase (HR 1.05, 95% CI 1.03-1.07, p < 0.01), and lactate dehydrogenase (LDH) (HR 1.27, 95% CI 1.12-1.45, p < 0.01), whereas oxygen index (HR 0.990, 95% CI 0.988-0.992, p < 0.01), partial pressure of oxygen (HR 0.933, 95% CI 0.906-0.961, p < 0.01), forced vital capacity (HR 0.962, 95% CI 0.928-0.998, p = 0.038), and lymphocyte count (HR 0.421, 95% CI 0.282-0.629, p < 0.01) were associated with better outcomes.
CONCLUSIONS
Old age, male sex, hypoxemia, low forced vital capacity, lymphocytopenia, and high levels of ferritin, CRP, creatine kinase, and LDH are risk factors for mortality in patients with MDA5+ DM. However, a cautious interpretation of these results and further quality investigation are warranted.
