Review
BACKGROUND
Endotracheal suctioning consists of the mechanical aspiration of pulmonary secretions from the endotracheal tube (ETT) to prevent obstruction. The optimal frequency of ETT suctioning has not been defined.
OBJECTIVES
To determine the effect of specific ordered frequency of ETT suctioning ('as scheduled') versus ETT suctioning only in case of indications ('as needed') and of more frequent ETT suctioning versus less frequent ETT suctioning on respiratory morbidity in ventilated newborns.
SEARCH METHODS
We used the standard search strategy of the Cochrane Neonatal Review group to search the Cochrane Central Register of Controlled Trials (CENTRAL 2015, Issue 10), MEDLINE via PubMed (1966 to 31 October 2015), EMBASE (1980 to 31 October 2015), and CINAHL (1982 to 31 October 2015). We checked the reference lists of retrieved articles and contacted study authors to identify additional studies. We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomized controlled trials and quasi-randomized trials.
SELECTION CRITERIA
Randomized, quasi-randomized, and cluster randomized controlled trials comparing different strategies regarding the frequency of ETT suctioning of newborn infants receiving ventilator support.
DATA COLLECTION AND ANALYSIS
We used the standard methods of the Cochrane Neonatal Review Group. Two review authors independently extracted data and assessed the risk of bias of trials. The primary outcome was bronchopulmonary dysplasia or chronic lung disease.
MAIN RESULTS
We identified one randomized controlled study recruiting 97 low birthweight infants that met the inclusion criteria. The study was conducted in the UK in 1987 and 1988. Randomized infants received ETT suctioning every six or 12 hours during the first three days of life. The quality of reporting was limited and we rated the trial at high risk of bias. Furthermore, the trial lacked adequate power. There were no statistically significant differences in any of reported outcomes: bronchopulmonary dysplasia (defined as oxygen at more than 30 days; risk ratio (RR) 0.49, 95% confidence interval (CI) 0.20 to 1.20); incidence of pneumothorax (RR 0.70, 95% CI 0.24 to 2.05); intraventricular hemorrhage (RR 1.12, 95% CI 0.44 to 2.85); neonatal death (RR 1.40, 95% CI 0.58 to 3.37); and time on ventilation (median time 39 hours in the 12-hourly group and 28 hours in the six-hourly group; RD not applicable for this outcome as mean and standard deviation were not reported). Tests for heterogeneity were not applicable as only one study was included.
AUTHORS' CONCLUSIONS
There was insufficient evidence to identify the ideal frequency of ETT suctioning in ventilated neonates. Future research should focus on the effects in the very preterm newborns, that is, the most vulnerable population as concerns the risk of both lung and brain damage. Assessment should include the cases of prolonged ventilation, when more abundant, dense secretions are common. Clinical trials might include comparisons between 'as-scheduled' versus 'as-needed' endotracheal suctioning, that is, based on specific indications, as well frequent versus less frequent suctioning schedules.

Review
BACKGROUND
The high burden of pressure ulcers (PUs) in Sub-Saharan Africa (SSA), coupled with the limited resources, underscores the need for preventive and context-specific treatment strategies.
PURPOSE
Therefore, the purpose of this systematic review was to establish and elucidate PU prevention and treatment interventions tested in SSA.
METHODS
This systematic review of the literature used, PRISMA to guide the search.
FINDINGS
The review identified nine studies on PU prevention (three) and treatment (six). Low-cost interventions assembled from locally available materials and multifaceted policies significantly prevented and treated PUs. The interventions included wound dressing agents, simple negative pressure suction devices that significantly treated PUs, and water-based bed surfaces.
DISCUSSION
There were gaps in the interventions that have been proven successful in other global settings.
CONCLUSION
In SSA, there is a need for nurses to tailor, test, and disseminate findings from evidence-based projects for PU prevention that have been successful in similar settings.

Review
OBJECTIVE
Postpartum hemorrhage is a leading cause of maternal mortality and morbidity around the globe. The novel low-suction vacuum hemorrhage device (VHD) provides an alternative treatment option for cases of postpartum hemorrhage when first-line uterotonic agents fail. This systematic review aims to review current data evaluating the overall efficacy and safety of VHDs in treating postpartum hemorrhage.
METHODS
We searched CINAHL Ultimate, Academic Search Premier, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, MEDLINE with Full Text, and PubMed and reference lists of retrieved studies for eligible studies that included outcomes of effectiveness, efficacy, or safety. Two independent reviewers used Covidence.org to screen Titles and Abstracts for 69 studies of which six were included in the analysis. Secondary outcomes measured across studies included time to bleeding control, total device deployment time, and adverse effects.
RESULTS
Six nonrandomized trials ( = 1018 participants) included studies conducted in Indonesia, the United States, Switzerland, and Canada. The VHDs were found to have 90% effectiveness in achieving bleeding control across the studies. For most patients, this was achieved in <5 min and required a total device deployment time of 3 h. Reported adverse events were not considered life-threatening, including endometritis in 11 patients and red blood cell transfusions in 38% of patients.
CONCLUSION
VHDs have the potential to be used as a rapidly effective means for mechanical intervention of postpartum hemorrhage. The efficacy and safety of VHDs must be further studied at the randomized controlled trial level to determine their clinical usage.

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
Endoscopic ultrasound (EUS)-guided tissue acquisition has emerged over the last decade as an invaluable diagnostic tool in approaching the different pancreatic lesions. Given the safety and minimal invasiveness of this approach combined with the high diagnostic yield, it became the standard of care when dealing with different pancreatic pathologies. However, some variables regarding this procedure remain not fully understood. These can influence the diagnostic yield of the procedure and include the presence of the on-site cytopathologist, the type and size of the needle used as well as obtaining aspiration versus core biopsy, the number of passes and the sampling technique, and the role of suction and stylet use among others. We performed a comprehensive literature search using PubMed, Google Scholar, and Embase for studies that assessed these variables. Eligible studies were analyzed using several parameters such as technique and procedure, with the aim of reviewing results from an evidence-based standpoint.

Assessment of Effectiveness and Safety of Aspiration-Assisted Nephrostomic Access Sheaths in PCNL and Intrarenal Pressures Evaluation: A Systematic Review of the Literature.
Different suction-assisted nephrostomic sheaths have been developed for percutaneous nephrolithotomy (PCNL). (1) To examine PCNL techniques performed with different aspiration-assisted sheaths (Clear Petra sheath, Superperc, SuperminiPCNL, and a miniPCNL patented sheath), with specific regard to effectiveness and safety outcomes in adult and paediatric patients; (2) to extrapolate intrarenal pressure (IRP) data during these procedures. A systematic literature search was performed in accordance with PRISMA guidelines. Relevant articles up to 8 February 2024 were included. Twenty-five studies were selected, thirteen retrospective and twelve prospective. The use of four different aspirating sheaths for miniPCNL was reported: Clear Petra sheath, Superperc, SuperminiPCNL, and a miniPCNL patented sheath. Stone free rates (SFRs) across techniques ranged from 71.3% to 100%, and complication rates from 1.5% to 38.9%. Infectious complication rates varied from 0 to 27.8% and bleeding complication rates from 0 to 8.9%. Most complications were low grade ones. The trend among studies comparing aspiration- and non-aspiration-assisted miniPCNL was towards equivalent or better SFRs and lower overall infectious and bleeding complication rates in suction techniques. Operation time was consistently lower in suction procedures, with a mean shortening of the procedural time of 19 min. Seven studies reported IRP values during suction miniPCNL. Two studies reported satisfactory SFRs and adequate safety profiles in paediatric patient cohorts. MiniPCNL with aspirating sheaths appears to be safe and effective in both adult and paediatric patients. A trend towards a reduction of overall infectious and bleeding complications with respect to non-suction procedures is evident, with comparable or better SFRs and consistently shorter operative times. The IRP profile seems to be safe with the aid of aspirating sheaths. However, high quality evidence on this topic is still lacking.

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.

Meta-Analysis Review
BACKGROUND
Children with severe global developmental delay (SGDD) have significant intellectual disability and severe motor impairment; they are extremely limited in their functional movement and are dependent upon others for all activities of daily living. SGDD does not directly cause lung dysfunction, but the combination of immobility, weakness, skeletal deformity and parenchymal damage from aspiration can lead to significant prevalence of respiratory illness. Respiratory pathology is a significant cause of morbidity and mortality for children with SGDD; it can result in frequent hospital admissions and impacts upon quality of life. Although many treatment approaches are available, there currently exists no comprehensive review of the literature to inform best practice. A broad range of treatment options exist; to focus the scope of this review and allow in-depth analysis, we have excluded pharmaceutical interventions.
OBJECTIVES
To assess the effects of non-pharmaceutical treatment modalities for the management of respiratory morbidity in children with severe global developmental delay.
SEARCH METHODS
We conducted comprehensive searches of the following databases from inception to November 2013: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, the Allied and Complementary Medicine Database (AMED) and the Cumulative Index to Nursing and Allied Health Literature (CINAHL). We searched the Web of Science and clinical trials registries for grey literature and for planned, ongoing and unpublished trials. We checked the reference lists of all primary included studies for additional relevant references.
SELECTION CRITERIA
Randomised controlled trials, controlled trials and cohort studies of children up to 18 years of age with a diagnosis of severe neurological impairment and respiratory morbidity were included. Studies of airways clearance techniques, suction, assisted coughing, non-invasive ventilation, tracheostomy and postural management were eligible for inclusion.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures as expected by The Cochrane Collaboration. As the result of heterogeneity, we could not perform meta-analysis. We have therefore presented our results using a narrative approach.
MAIN RESULTS
Fifteen studies were included in the review. Studies included children with a range of severe neurological impairments in differing settings, for example, home and critical care. Several different treatment modalities were assessed, and a wide range of outcome measures were used. Most studies used a non-randomised design and included small sample groups. Only four randomised controlled trials were identified. Non-randomised design, lack of information about how participants were selected and who completed outcome measures and incomplete reporting led to high or unclear risk of bias in many studies. Results from low-quality studies suggest that use of non-invasive ventilation, mechanically assisted coughing, high-frequency chest wall oscillation (HFCWO), positive expiratory pressure and supportive seating may confer potential benefits. No serious adverse effects were reported for ventilatory support or airway clearance interventions other than one incident in a clinically unstable child following mechanically assisted coughing. Night-time positioning equipment and spinal bracing were shown to have a potentially negative effect for some participants. However, these findings must be considered as tentative and require testing in future randomised trials.
AUTHORS' CONCLUSIONS
This review found no high-quality evidence for any single intervention for the management of respiratory morbidity in children with severe global developmental delay. Our search yielded data on a wide range of interventions of interest. Significant differences in study design and in outcome measures precluded the possibility of meta-analysis. No conclusions on efficacy or safety of interventions for respiratory morbidity in children with severe global developmental delay can be made based upon the findings of this review.A co-ordinated approach to future research is vital to ensure that high-quality evidence becomes available to guide treatment for this vulnerable patient group.

Meta-Analysis Review
BACKGROUND
Polycystic ovarian syndrome (PCOS) is one of the most common reproductive endocrinology abnormalities, and affects 5% to 10% of women of reproductive age. Western medicines, such as oral contraceptives, insulin sensitizers and laparoscopic ovarian drilling (LOD), have been used to treat PCOS. Recently, many studies have been published that consider Chinese herbal medicine (CHM) as an alternative treatment for women with PCOS.
OBJECTIVES
To assess the efficacy and safety of CHM for subfertile women with PCOS.
SEARCH METHODS
We searched sources, including the following databases, from inception to 9 June 2016: the Cochrane Gynaecology and Fertility Group Specialized Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, Allied and Complementary Medicine (AMED), PsycINFO, Chinese National Knowledge Infrastructure (CNKI), VIP, Wanfang and trial registries. In addition, we searched the reference lists of included trials and contacted experts in the field to locate trials.
SELECTION CRITERIA
Randomized controlled trials (RCTs) that considered the use of CHM for the treatment of subfertile women with PCOS.
DATA COLLECTION AND ANALYSIS
Two review authors independently screened appropriate trials for inclusion, assessed the risk of bias in included studies and extracted data. We contacted primary study authors for additional information. We conducted meta-analyses. We used the odds ratios (ORs) to report dichotomous data, with 95% confidence intervals (CI). We assessed the quality of the evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methods.
MAIN RESULTS
We included five RCTs with 414 participants. The comparisons in the included trials were as follows: CHM versus clomiphene, CHM plus clomiphene versus clomiphene (with or without ethinyloestradiol cyproterone acetate (CEA)), CHM plus follicle aspiration plus ovulation induction versus follicle aspiration plus ovulation induction alone, and CHM plus laparoscopic ovarian drilling (LOD) versus LOD alone. The overall quality of the evidence for most comparisons was very low.None of the included studies reported live birth rate, and only one study reported data on adverse events.When CHM was compared with clomiphene (with or without LOD in both arms), there was no evidence of a difference between the groups in pregnancy rates (odds ratio (OR) 1.98, 95% confidence interval (CI) 0.78 to 5.06; two studies, 90 participants, I² statistic = 0%, very low quality evidence). No study reported data on adverse events. When CHM plus clomiphene was compared with clomiphene (with or without CEA), there was low quality evidence of a higher pregnancy rate in the CHM plus clomiphene group (OR 2.62, 95% CI 1.65 to 4.14; three RCTs, 300 women, I² statistic = 0%,low quality evidence). No data were reported on adverse events.When CHM with follicle aspiration and ovulation induction was compared with follicle aspiration and ovulation induction alone, there was no evidence of a difference between the groups in pregnancy rates (OR 1.60, 95% CI 0.46 to 5.52; one study, 44 women, very low quality evidence), severe luteinized unruptured follicle syndrome (LUFS) (OR 0.60, 95% CI 0.06 to 6.14; one study, 44 women, very low quality evidence), ovarian hyperstimulation syndrome (OHSS) (OR 0.16, 95% CI 0.00 to 8.19; one study, 44 women, very low quality evidence) or multiple pregnancy (OR 0.60, 95% CI 0.06 to 6.14; one study, 44 women, very low quality evidence).When CHM with LOD was compared with LOD alone, there was no evidence of a difference between the groups in rates of pregnancy (OR 3.50, 95% CI 0.72 to 17.09; one study, 30 women, very low quality evidence), No data were reported on adverse events.There was no evidence of a difference between any of the comparison groups for any other outcomes. The quality of the evidence for all other comparisons and outcomes was very low. The main limitations in the evidence were failure to report live birth or adverse events, failure to describe study methods in adequate detail and imprecision due to very low event rates and wide CIs.
AUTHORS' CONCLUSIONS
There is insufficient evidence to support the use of CHM for women with PCOS and subfertility. No data are available on live birth, and there is no consistent evidence to indicate that CHM influences fertility outcomes. However there is very limited low quality evidence to suggest that the addition of CHM to clomiphene may improve pregnancy rates. There is insufficient evidence on adverse effects to indicate whether CHM is safe.

Meta-Analysis Review
Comparison of microdissection testicular sperm extraction, conventional testicular sperm extraction, and testicular sperm aspiration for nonobstructive azoospermia: a systematic review and meta-analysis.
OBJECTIVE
To investigate the relative differences in outcomes among microdissection testicular sperm extraction (micro-TESE), conventional testicular sperm extraction (cTESE), and testicular sperm aspiration (TESA) in men with nonobstructive azoospermia.
DESIGN
Systematic review and meta-analysis.
SETTING
Outpatient academic and private urology clinics.
PATIENTS(S)
Men with nonobstructive azoospermia.
INTERVENTION(S)
Micro-TESE, cTESE, or TESA.
MAIN OUTCOME MEASURE(S)
Sperm retrieval (SR).
RESULT(S)
Fifteen studies with a total of 1,890 patients were identified. The weighted average age of the patients was 34.4 years, the follicular stimulating hormone level was 20.5 mIU/mL, the T was 373 ng/dL, and the testicular volume was 13.5 mL. In a direct comparison, performance of micro-TESE was 1.5 times more likely (95% confidence interval 1.4-1.6) to result in successful SR as compared with cTESE. Similarly, in a direct comparison, performance of cTESE was 2.0 times more likely (95% confidence interval 1.8-2.2) to result in successful SR as compared with TESA. Because of inconsistent reporting, evaluation of other procedural characteristics and pregnancy outcomes was not possible.
CONCLUSION(S)
Sperm retrieval was higher for micro-TESE compared with cTESE and for cTESE compared with TESA. Standardization of reported outcomes as well as combining all available SR data would help to further elucidate the SRs of these procedures.
