Meta-Analysis
Comparison of the efficacy and safety of conventional curettage adenoidectomy with those of other adenoidectomy surgical techniques: a systematic review and network meta-analysis.
OBJECTIVES
There is a lack of robust evidence in regards to whether the intra and post-operative safety and efficacy of conventional curettage adenoidectomy is better than those of other available surgical techniques. Therefore, this study was conducted as a systematic review and network meta-analysis of published randomized controlled trials (RCTs) with the aim of comparing the safety and efficacy of conventional curettage adenoidectomy with all other available adenoidectomy techniques.
MATERIALS AND METHODS
A systematic search of published articles was performed in 2021 using databases such as PubMed/Medline, EMBASE, EBSCO, and the Cochrane Library. All RCTs that compared conventional curettage adenoidectomy with other surgical techniques and were published in English between 1965 and 2021 were included. The quality of the included RCTs have been assessed using Cochrane Collaboration Risk of Bias Tool.
RESULTS
After screening 1494 articles, 17 were identified for comparing several adenoidectomy techniques and were eligible for quantitative analysis. Of those, 9 RCTs were analyzed for intraoperative blood loss, and 6 articles were included for post-operative bleeding. Furthermore; 14, 10, and 7 studies were included for surgical time, residual adenoid tissue, and postoperative complications respectively. Endoscopic-assisted microdebrider adenoidectomy yielded a statistically significantly greater estimate of intraoperative blood loss compared with conventional curettage adenoidectomy (mean difference [MD], 92.7; 95% confidence interval [CI] 28.3-157.1), suction diathermy (MD, 117.1; 95% CI 37.2-197.1). Suction diathermy had the highest cumulative probability of being the preferred technique because it was estimated to result in the least intraoperative blood loss. Electronic molecular resonance adenoidectomy was estimated to be more likely to result in the shortest surgical time (mean rank, 2.2). Participants in the intervention group were 97% less likely to have residual adenoid tissue than children in the conventional curettage group (odds ratio 0.03; 95% CI 0.01-0.15); therefore, conventional curettage was not considered an appropriate technique for complete removal of adenoid tissue.
CONCLUSION
There is no single technique that can be considered best for all possible outcomes. Therefore, otolaryngologists should make an appropriate choice after critically reviewing the clinical characteristics of children requiring adenoidectomy. Findings of this systematic review and meta-analysis may guide otolaryngologists when making evidence-based decisions regarding the treatment of enlarged and symptomatic adenoids in children.

Review
The aim of this systematic review and meta-analysis is the comparison of endotracheal intubation and suctioning to immediate resuscitation without intubation of non-vigorous infants > 34 weeks’ gestation delivered through meconium-stained amniotic fluid (MSAF). Randomized, non-randomized clinical trials and observational studies were included. Data sources were PubMed/Medline and Cochrane Central Registry of Controlled Trials, from 2012 to 2021. Inclusion criteria were non-vigorous infants born through MSAF with gestational age > 34 weeks and sample size ≥ 5. We calculated overall relative risks (RR) and mean differences (MD) with a 95% confidence interval (CI) to determine the impact of endotracheal suction (ETS) in non-vigorous infants born through MSAF. The outcomes presented are the incidence of neonatal mortality, meconium aspiration syndrome (MAS), transient tachypnea, need for positive pressure ventilation, respiratory support, persistent pulmonary hypertension treatment, neonatal infection, ischemic encephalopathy, admission to neonatal intensive care unit (NICU) and the duration of hospitalization between ETS and non-ETS group. Six studies with a total sample of 1026 patients fulfilled the inclusion criteria. Statistically non-significant difference was observed in RR between two groups with regards to mortality (1.22, 95% CI 0.73−2.04), occurrence of MAS (1.08, 95% CI 0.76−1.53) and other outcomes, and MD in hospitalization duration. There is no sufficient evidence to suggest initiating endotracheal suction soon after birth in non-vigorous meconium-stained infants as routine.

Meta-Analysis Review
BACKGROUND
This is an updated version of an original Cochrane review published in Issue 6, 2014. Pelvic lymphadenectomy is associated with significant complications including lymphocyst formation and related morbidities. Retroperitoneal drainage using suction drains has been recommended as a method to prevent such complications. However, findings from recent studies have challenged this policy.
OBJECTIVES
To assess the effects of retroperitoneal drainage versus no drainage after pelvic lymphadenectomy on lymphocyst formation and related morbidities in women with gynaecological cancer.
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 3, 2017) in the Cochrane Library, electronic databases MEDLINE (1946 to March Week 2, 2017), Embase (1980 to 2017 week 12), and the citation lists of relevant publications. We also searched the trial registries for ongoing trials on 20 May 2017.
SELECTION CRITERIA
Randomised controlled trials (RCTs) that compared the effect of retroperitoneal drainage versus no drainage after pelvic lymphadenectomy in women with gynaecological cancer. Retroperitoneal drainage was defined as placement of passive or active suction drains in pelvic retroperitoneal spaces. No drainage was defined as no placement of passive or active suction drains in pelvic retroperitoneal spaces.
DATA COLLECTION AND ANALYSIS
We assessed studies using methodological quality criteria. For dichotomous data, we calculated risk ratios (RRs) and 95% confidence intervals (CIs). We examined continuous data using mean difference (MD) and 95% CI.
MAIN RESULTS
Since the last version of this review, we have identified no new studies for inclusion. The review included four studies with 571 women. Regarding short-term outcomes (within four weeks after surgery), retroperitoneal drainage was associated with a comparable rate of overall lymphocyst formation when all methods of pelvic peritoneum management were considered together (2 studies; 204 women; RR 0.76, 95% CI 0.04 to 13.35; moderate-quality evidence). When the pelvic peritoneum was left open, the rates of overall lymphocyst formation (1 study; 110 women; RR 2.29, 95% CI 1.38 to 3.79) and symptomatic lymphocyst formation (2 studies; 237 women; RR 3.25, 95% CI 1.26 to 8.37) were higher in the drained group. At 12 months after surgery, the rates of overall lymphocyst formation were comparable between the groups (1 study; 232 women; RR 1.48, 95% CI 0.89 to 2.45; high-quality evidence). However, there was a trend toward increased risk of symptomatic lymphocyst formation in the group with drains (1 study; 232 women; RR 7.12, 95% CI 0.89 to 56.97; low-quality evidence).
AUTHORS' CONCLUSIONS
Placement of retroperitoneal tube drains has no benefit in the prevention of lymphocyst formation after pelvic lymphadenectomy in women with gynaecological malignancies. When the pelvic peritoneum is left open, the tube drain placement is associated with a higher risk of short- and long-term symptomatic lymphocyst formation. We found the quality of evidence using the GRADE approach to be moderate to high for most outcomes, except for symptomatic lymphocyst formation at 12 months after surgery, and unclear or low risk of bias.

Meta-Analysis
BACKGROUND
Several randomized controlled trials (RCTs) and observational studies have compared the efficacy of digital chest drainage system versus traditional chest drainage system. However, the results were inconsistent.
METHODS
We searched the Web of Science and Pubmed for observational studies and RCTs that compared the effect of digital chest drainage system with traditional chest drainage system after pulmonary resection. Eight studies (5 randomized control trails and 3 observational studies) comprising 1487 patients met the eligibility criteria.
RESULTS
Compared with the traditional chest drainage system, digital chest drainage system reduced the risk of prolonged air leak (PAL) (RR = 0.54, 95%CI 0.40-0.73, p < 0.0001), and shortened the duration of chest drainage (SMD = - 0.35, 95%CI -0.60 - -0.09, p = 0.008) and length of hospital stay (SMD = - 0.35, 95%CI -0.61 - -0.09, p = 0.007) in patients after pulmonary resection.
CONCLUSIONS
Digital chest drainage system is expected to benefit patients to attain faster recovery and higher life quality as well as to reduce the risk of postoperative complications. Further RCTs with larger sample size are still needed to more clearly elucidate the advantages of digital chest drainage system.

Review
BACKGROUND
During childbirth, complications may arise which necessitate an expedited delivery of the fetus. One option is instrumental assistance (forceps or a vacuum-cup), which, if used with skill and sensitivity, can improve maternal/neonatal outcomes. This review aimed to understand the core competencies and expertise required for skilled use in AVD in conjunction with reviewing potential barriers and facilitators to gaining competency and expertise, from the point of view of maternity care practitioners, funders and policy makers.
METHODS
A mixed methods systematic review was undertaken in five databases. Inclusion criteria were primary studies reporting views, opinions, perspectives and experiences of the target group in relation to the expertise, training, behaviours and competencies required for optimal AVD, barriers and facilitators to achieving practitioner competencies, and to the implementation of appropriate training. Quality appraisal was carried out on included studies. A mixed-methods convergent synthesis was carried out, and the findings were subjected to GRADE-CERQual assessment of confidence.
RESULTS
31 papers, reporting on 27 studies and published 1985-2020 were included. Studies included qualitative designs (3), mixed methods (3), and quantitative surveys (21). The majority (23) were from high-income countries, two from upper-middle income countries, one from a lower-income country: one survey included 111 low-middle countries. Confidence in the 10 statements of findings was mostly low, with one exception (moderate confidence). The review found that AVD competency comprises of inter-related skill sets including non-technical skills (e.g. behaviours), general clinical skills; and specific technical skills associated with particular instrument use. We found that practitioners needed and welcomed additional specific training, where a combination of teaching methods were used, to gain skills and confidence in this field. Clinical mentorship, and observing others confidently using the full range of instruments, was also required, and valued, to develop competency and expertise in AVD. However, concerns regarding poor outcomes and litigation were also raised.
CONCLUSION
Access to specific AVD training, using a combination of teaching methods. Complements, but does not replace, close clinical mentorship from experts who are positive about AVD, and opportunities to practice emerging AVD skills with supportive supervision. Further research is required to ascertain effective modalities for wider training, education, and supportive supervision for optimal AVD use.

Review
BACKGROUND
Endotracheal suctioning for mechanically ventilated infants is routine practice in neonatal intensive care. However, this practice is associated with serious complications including lobar collapse, pneumothorax, bradycardia and hypoxemia. Increasing the inspired oxygen immediately prior to suction (preoxygenation) has been proposed as an intervention to minimise the risk of complications.
OBJECTIVES
To compare the effects of preoxygenation with no preoxygenation for endotracheal suctioning on ventilated newborn infants. To conduct sub group analyses by i) different populations of newborn infants; by gestational age <30 weeks, <34 weeks and <37 weeks and by disease; infants with chronic lung disease compared to those without and; ii) by different techniques of endotracheal suctioning; with or without disconnection from the ventilator, increased mechanical ventilation, use of manual ventilation and chest wall vibrations or percussion.
SEARCH STRATEGY
The standard search strategy of the Neonatal Review Group was used. This included searches of electronic databases; Oxford Database of Perinatal Trials; Cochrane Controlled Trials Register (Cochrane Library Issue 1 2001); MEDLINE (1966 - April 2001); and CINAHL (1982-2001) using MeSH term infant-newborn and text terms oxygen* and suction*, preoxygenation, pre-oxygenation and premature and also previous reviews including cross references, abstracts in conferences and symposia proceedings, expert informants, journal hand searching in the English language.
SELECTION CRITERIA
Random or quasi random controlled trials of mechanically ventilated neonates in which endotracheal suctioning with preoxygenation was compared to suctioning without preoxygenation.
DATA COLLECTION AND ANALYSIS
Standard methods of the Cochrane Collaboration and its Neonatal Review Group were used, including independent assessment of trial quality and extraction of data by the authors. Data were analysed using relative risk (RR) for dichotomous outcomes and mean difference (MD) for data measured on a continuous scale with the use of 95% confidence intervals. Meta-analysis was conducted using a fixed effects model.
MAIN RESULTS
One cross-over trial involving outcomes for 16 preterm neonates was included in this review. Preoxygenation, prior to an endotracheal suctioning procedure involving two suctions, resulted in a statistically significant reduction in infants with hypoxemia (TcPO2 <40 mmHg) at the end of the first suction (RR 0.18, 95% CI 0.05, 0.69), at the end of the second suction (RR 0.23, 95% CI 0.08, 0.66) and also at 120 seconds after the second suction (RR 0.10, 95% CI 0.01, 0.69). Mean TcPO2 was statistically significantly higher in the preoxygenation group at the end of the first suction (MD 25.00 mmHg, 95%CI 14.20, 35.80), second suction (MD 24.80, 95% CI 14.80, 34.80) and also at 120 seconds after the second suction (MD 29.10, 95% CI 14.96, 43.24). The time taken to return to baseline oxygenation status was shorter than the group not receiving preoxygenation (MD -2.12 minutes, 95% CI -3.82, -0.42).
REVIEWER'S CONCLUSIONS
No recommendations for practice can be confidently made from the results of this review. Although preoxygenation was shown to decrease hypoxemia at the time of suctioning, other clinically important short and longer-term outcomes including adverse effects were unable to be assessed. Further studies are needed to adequately assess the effects of this widely practiced procedure.

Meta-Analysis Review
This review is an attempt to untangle the complexity of transtibial prosthetic socket fit and perhaps find some indication of whether a particular prosthetic socket type might be best for a given situation. In addition, we identified knowledge gaps, thus providing direction for possible future research. We followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, using medical subject headings and standard key words to search for articles in relevant databases. No restrictions were made on study design and type of outcome measure used. From the obtained search results (n = 1,863), 35 articles were included. The relevant data were entered into a predefined data form that included the Downs and Black risk of bias assessment checklist. This article presents the results from the systematic review of the quantitative outcomes (n = 27 articles). Trends indicate that vacuum-assisted suction sockets improve gait symmetry, volume control, and residual limb health more than other socket designs. Hydrostatic sockets seem to create less inconsistent socket fittings, reducing a problem that greatly influences outcome measures. Knowledge gaps exist in the understanding of clinically meaningful changes in socket fit and its effect on biomechanical outcomes. Further, safe and comfortable pressure thresholds under various conditions should be determined through a systematic approach.

Meta-Analysis Review
BACKGROUND
This is an updated version of the original Cochrane review published in Issue 1, 2010. Pelvic lymphadenectomy is associated with significant complications including lymphocyst formation and related morbidities. Retroperitoneal drainage using suction drains has been recommended as a method to prevent such complications. However, this policy has been challenged by the findings from recent studies.
OBJECTIVES
To assess the effects of retroperitoneal drainage versus no drainage after pelvic lymphadenectomy on lymphocyst formation and related morbidities in gynaecological cancer patients.
SEARCH METHODS
We searched the Cochrane Gynaecological Cancer Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL 2013, Issue 12) in The Cochrane Library, electronic databases MEDLINE (Nov Week 3, 2013), EMBASE (2014, week 1), and the citation lists of relevant publications. The latest searches were performed on 10 January 2014.
SELECTION CRITERIA
Randomised controlled trials (RCTs) that compared the effect of retroperitoneal drainage versus no drainage after pelvic lymphadenectomy in gynaecological cancer patients. Retroperitoneal drainage was defined as placement of passive or active suction drains in pelvic retroperitoneal spaces. No drainage was defined as no placement of passive or active suction drains in pelvic retroperitoneal spaces.
DATA COLLECTION AND ANALYSIS
We assessed studies using methodological quality criteria. For dichotomous data, we calculated risk ratios (RRs) and 95% confidence intervals (CIs). We examined continuous data using mean difference (MD) and 95% CI.
MAIN RESULTS
Since the last version of this review, no new studies have been identified for inclusion. The review included four studies with 571 participants. Considering the short-term outcomes (within four weeks after surgery), retroperitoneal drainage was associated with a comparable rate of overall lymphocyst formation when all methods of pelvic peritoneum management were considered together (two studies, 204 patients; RR 0.76, 95% CI 0.04 to 13.35). When the pelvic peritoneum was left open, the rates of overall lymphocyst formation (one study, 110 patients; RR 2.29, 95% CI 1.38 to 3.79) and symptomatic lymphocyst formation (one study, 137 patients; RR 3.25, 95% CI 1.26 to 8.37) were higher in the drained group. At 12 months after surgery, the rates of overall lymphocyst formation were comparable between the groups (one study, 232 patients; RR 1.48, 95% CI 0.89 to 2.45). However, there was a trend toward increased risk of symptomatic lymphocyst formation in the group with drains (one study, 232 patients; RR 7.12, 95% CI 0.89 to 56.97). The included trials were of low to moderate risk of bias.
AUTHORS' CONCLUSIONS
Placement of retroperitoneal tube drains has no benefit in prevention of lymphocyst formation after pelvic lymphadenectomy in patients with gynaecological malignancies. When the pelvic peritoneum is left open, the tube drain placement is associated with a higher risk of short and long-term symptomatic lymphocyst formation.

Review
BACKGROUND
The 'reamer-irrigator-aspirator' (RIA) is an innovation developed to reduce fat embolism (FE) and thermal necrosis (TN) that can occur during reaming/nailing of long-bone fractures. Since its inception its indications have expanded to include the treatment of long-bone osteomyelitis and as a harvester of bone graft/mesenchymal stem cells (MSCs).
METHODS
This study involved a systematic review, via Pubmed® and Google Scholar®, of English language sources (nine non-clinical studies, seven clinical studies and seven case reports) using the keywords: 'reamer', 'irrigator', 'aspirator' (1st May 2010). Sources were reviewed with reference to the RIAs efficacy in (1) preventing FE/TN, (2) treating long-bone osteomyelitis, (3) harvesting bone graft/MSCs, and (4) operating safely. Experimental data supports the use of the RIA in preventing FE and TN, however, there is a paucity of clinical data.
CONCLUSIONS
The RIA is a reliable method in achieving high volumes of bone graft/MSCs, and high union rates are reported when using RIA bone-fragments to treat non-unions. Evidence suggests possible effectiveness in treating long-bone osteomyelitis. The RIA appears relatively safe, with a low rate of morbidity provided a meticulous technique is used. When complications occur they respond well to conventional techniques. The RIA demands further investigation especially with respect to the optimal application of MSCs for bone repair strategies.

INTRODUCTION
Ventilator-associated events (VAEs) are one of the main sources of concern in critically ill patients due to the high frequency and mortality. We conducted this analysis to compare the effects of open endotracheal suctioning system with closed one on the incidences of VAEs in adult patients receiving mechanical ventilation (MV).
MATERIALS AND METHODS
A comprehensive literature search was performed in PubMed, Scopus, Cochrane Library, and hand searching bibliographies of retrieved articles. The search was confined to randomized controlled trials with human adults comparing closed tracheal suction systems (CTSS) vs open tracheal suction systems (OTSS) in prevention of ventilator-associated pneumonia (VAP). Full-text articles were used in order to extract the data. Data extraction was only started after completing the quality assessment.
RESULTS
The search resulted in 59 publications. Among them, 10 were identified as eligible for meta-analysis. There was a significant increase in incidence of VAP when using OTSS compared to CTSS, so that OCSS increased the incidence of VAP by 57% (OR 1.57, 95% CI 1.063-2.32, = 0.02).
DISCUSSION
Our results showed that using CTSS can significantly decrease VAP development compared to OTSS. This conclusion does not yet mean the routine use of CTSS as a standard VAP prevention measure for all patients since individual patient's disease and cost are other factors that should be in mind when determining the choice of the suctioning system. High-quality trials with a larger sample size are highly recommended.
