Review
BACKGROUND
Postoperative intussusception (POI) is an unusual complication in children and infants who underwent various kinds of surgery. The early recognition was difficult for its rarity and atypical presentations. This study evaluates the clinical features of POI through a literature review.
METHODS
MEDLINE database was searched for relevant articles that reported the children and infants with POI since 1990 in English-language using the key word "postoperative intussusception". All published studies containing clinical data for POI in children and infants were included. Reference lists of retrieved articles were reviewed for additional cases. Detailed data of the included cases were extracted and analyzed.
RESULTS
Twenty-six studies with total 127 cases of POI were included. According to the extracted data, the median age was 19 months with the male-to-female ratio 1.5:1. There were 65 operations (51.2 %) that involved gastrointestinal system, 26 cases (20.5 %) of retroperitoneal tumor resection, 12 operations (9.4 %) involved diaphragm, 8 operations (6.3 %) involved urinary system, 5 cases (3.9 %) of partial pancreatectomy, 11 cases (8.7 %) of non-abdominal operations. 75.5 % presented symptoms in the first 7 days after surgery. The prominent symptom was bilious vomiting or increased nasogastric output (87.1 % of 101 patients), following abdominal distention (74.3 %), abdominal pain (35.6 %). Six cases (5.0 %) of ileocolic POI were reduced successfully by air enema. The small bowel intussusception attributed 85.6 % of POI (95 patients). Laparotomy and manual reduction were performed in 104 cases (86.0 %). Nine patients (7.4 %) underwent intestinal resection and anastomosis.
CONCLUSIONS
POI should be suspected in pediatric surgical patients who showed signs of intestinal obstruction in the early postoperative period. Early recognition and prompt management are important.

Meta-Analysis
OBJECTIVE
The vaginal ring (ring) is a female-initiated, long-acting drug delivery system for different indications, including HIV prevention. Our aim was to provide evidence for acceptability of the vaginal ring across indications to support dapivirine and multipurpose prevention technology ring introduction and roll out.
STUDY DESIGN
This systematic review and meta-analysis followed PRISMA guidelines. We searched PubMed, Web of Science, Embase, and grey literature for publications reporting favorable ring acceptability and secondary outcomes involving actual ring use (comfort, ease of ring use, ring comfort during sex, expulsions, and vaginal symptoms) or hypothetical acceptability for any indication published January 1, 1970-June 15, 2021. We estimated random-effects pooled prevalence, assessing between-study variation using meta-regression.
RESULTS
Of 2,234 records, we included 123 studies with 40,434 actual and hypothetical ring users. The primary outcome assessment included 50 studies with 60 ring subgroups totaling 19,271 ring users. The favorable acceptability pooled prevalence was 85.6% (95%CI 81.3, 89.0), while hypothetical acceptability among non-ring users was 27.6% (95%CI 17.5, 40.5). In meta-regression, acceptability was higher in menopause (95.4%; 95%CI 88.4, 98.2) compared to contraceptive rings (83.7%; 95%CI 75.6, 89.5). Acceptability was lower in pharmacokinetic studies (50%; 95%CI 22.1, 77.9) compared to RCTs (89.5%; 95%CI 85.8.92.4) and in studies assessing acceptability at ≥12 months (78.5%; 95%CI 66.5, 87.1) versus studies assessing acceptability at <3 months (91.9%; 95%CI 83.7, 96.1). European (90.6%; 95%CI 83.9, 94.7), Asian (97.1%; 95%CI 92.0, 99.0), and multi-region studies (93.5%; 95%CI 84.6, 97.4) reported more favorable acceptability compared to African studies (59.4%; 95%CI 38.3, 77.5). Secondary outcomes were similarly favorable, including ring comfort (92.9%; 95%CI 89.2, 95.4), ease of use (90.9%; 95%CI 86.5, 94.0), and comfort during sex (82.7%; 95%CI 76.4, 87.6). Limitations include inconsistent outcome definitions and unmeasured factors affecting acceptability.
CONCLUSIONS
Women who used vaginal rings reported they were acceptable across indications geographic regions and indications. Policy makers should consider the ring as an important option for pregnancy and HIV prevention drug development.
IMPLICATIONS
This review found favorable acceptability among vaginal ring users across indications and geographic areas, in contrast to low hypothetical acceptability among non-users. Vaginal rings are an important drug delivery system for pregnancy and HIV preventions, and scale-up should plan to address initial hesitancy among new users.

Review
STUDY OBJECTIVE
Adolescents are at high risk for unintended pregnancies. Although intrauterine devices (IUDs), long-acting reversible contraceptives (LARCs), are known to be highly effective in preventing pregnancy, little is known about IUD adherence in adolescents. In this systematic review (SR) we examined IUD continuation rates compared with other forms of contraception in young women aged 25 years and younger. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: A systematic search of Ovid Medline, Cochrane Library, and Embase was conducted for the years 1946-2015. Included studies examined IUD use in women 25 years of age and younger, compared IUD use with another form of contraception, and measured continuation rates at 12 months. The quality of each study was appraised using the Downs and Black criteria, and 12-month continuation rates among studies were pooled and analyzed according to contraceptive type.
RESULTS
Of 3597 articles retrieved, 9 studies met criteria for SR. Synthesized across studies, 12-month continuation was significantly higher for IUD users (86.5%, 12,761/14,747) compared with oral contraceptives (39.6%, 1931/4873), Depo-Provera (Pfizer Inc, New York, NY) hormonal injection (39.8%, 510/1282), vaginal ring (48.9%, 196/401), and transdermal patch (39.8%, 37/93; all P values < .001). There was no statistically significant difference in 12-month continuation between the IUD and another LARC method, the subdermal etonogestrel implant (85.3%, 4671/5474).
CONCLUSION
Findings of this SR suggest that continuation rates for IUDs are generally higher compared with other contraceptive methods for women aged 25 years and younger. In a population with high rates of unintended pregnancies, generally low adherence, and imperfect use with other non-LARCs, IUD use should be encouraged.

JAMA Neurology Feb 2019Data on neurologic manifestations of fibromuscular dysplasia (FMD) are rare, and current knowledge remains limited.
IMPORTANCE
Data on neurologic manifestations of fibromuscular dysplasia (FMD) are rare, and current knowledge remains limited.
OBJECTIVES
To present a comprehensive review of the epidemiologic characteristics, management, and prognosis of the neurologic manifestations associated with cerebrovascular FMD (ie, involving cervical or intracranial arteries) and to guide future research priorities.
EVIDENCE REVIEW
References were identified through searches of PubMed from inception to December 2017 using both the medical subject headings and text words. Additional sources were also identified by reviewing reference lists of relevant articles and through searches of the authors' personal files. Selected articles described at least 1 clinical or radiologic feature and/or outcome of cerebrovascular FMD. Isolated case reports could be included if they described interesting or noteworthy manifestations of FMD.
FINDINGS
A total of 84 relevant references were identified. Diagnosis of cerebrovascular FMD is based on the appearance of alternating arterial dilatation and constriction ("string of beads") or of focal narrowing, with no sign of atherosclerotic or inflammatory lesions. Although the diagnosis is easily apparent on results of radiographic imaging, making a diagnosis can be challenging in children or individuals with atypical phenotypes, such as purely intracranial FMD and arterial diaphragm. Involvement of multiple arteries is common, and there is increased incidence of cervical artery dissection and intracranial aneurysms. A variant in the PHACTR1 gene has been associated with FMD as well as cervical artery dissection and migraine, although less than 5% of cases of FMD are familial. Headaches, mainly of the migraine type, are observed in up to 70% of patients with FMD. Cerebrovascular FMD is mostly asymptomatic, but the most frequent neurologic manifestations include transient ischemic attack and ischemic stroke, notably in the presence of associated cervical artery dissection. Other conditions associated with FMD include subarachnoid hemorrhage and, rarely, intracranial hemorrhage. Management relies on observational data and expert opinion. Antiplatelet therapy is considered reasonable to prevent thromboembolic complications. Endovascular therapy is typically restricted to cases with symptomatic stenosis despite optimal medical therapy or in those with rupture of an intracranial aneurysm.
CONCLUSIONS AND RELEVANCE
Longitudinal cohort studies of individuals of multiple ethnicities with biosampling are needed to better understand the risk factors, pathophysiological features, and outcomes of FMD. Patient advocacy groups could assist researchers in answering patient-centered questions regarding FMD.

Review
BACKGROUND
Levonorgestrel (LNG)-intrauterine devices (IUDs) are an effective method of contraception; however, there is growing evidence regarding potential psychiatric side effects such as depressive symptoms, anxiety, and suicidal thoughts. Therefore, we conducted this systematic review to summarise the psychiatric effects of using LNG-IUDs.
METHODS
We searched six databases (MEDLINE, Web of Science, Scopus, Science Direct, Cochrane Library, and PsycInfo), and we included all study designs. The included studies were extracted, quality assessed, and qualitatively summarised.
RESULTS
Out of the screened studies, only 22 were finally included. While ten studies showed increased depressive symptoms, two studies showed reduced symptoms. Moreover, one study showed increased anxiety, another one reported an increased risk of suicide, four studies concluded no association with depressive symptoms, and four other studies showed uncertainty about a potential association but mentioned other psychiatric symptoms.
CONCLUSION
Despite unreliable data, many studies report psychiatric symptoms associated with LNG-IUDs, predominantly depression. Gynaecologists, general practitioners, and psychiatrists should therefore be aware of these potential risks, especially depressive symptoms and suicidality. Counselling patients about these risks should be mandatory. Further studies should investigate the absolute risk of mental disorders associated with LNG-IUDs and other hormonal contraceptives.KEY MESSAGESMany researchers are reporting adverse psychiatric events associated with levonorgestrel intrauterine devices (LNG-IUDs).Despite their effectiveness, a proper psychiatric assessment should be done before inserting LNG-IUDs.Proper counselling regarding the depressive symptoms and suicidality should be done by the treating obstetrician.Further studies should investigate the absolute risk of mental disorders associated with LNG-IUDs and other hormonal contraceptives.

PURPOSE
Patients with respiratory failure associated with neurological dysfunction often require mechanical ventilator support, which poses increased economic burden and ventilator-associated complications. A diaphragm pacing system (DPS) is an implanted device that provides respiratory support for such patients. In this systematic review, we reviewed the literature to assess the safety and efficacy of DPS for patients with respiratory failure resulting from amyotrophic lateral sclerosis (ALS) or cervical spinal cord injuries.
MATERIALS AND METHODS
The following databases were searched from July 10 to July 30, 2018: MEDLINE, EMBASE, Cochran library, KoreaMed, Research Information Sharing Service, Korean studies Information Service System, Korea Institute of Science and Technology Information, and Korean Medical database. The abstracts and full texts of the searched articles were reviewed by two reviewers.
RESULTS
The search keywords generated 197 articles: two randomized controlled trials, two case-control studies, and one case report involving patients with ALS; one cohort study, one case-control study, and two case reports involving patients with cervical spine injury; and one case report involving patients with both conditions were included. The primary outcome was safety profile (complications and adverse event) and efficacy (overall survival and sleep improvement). Complications and adverse events were more common in patients with ALS and spinal cord injury receiving DPS than in controls. Efficacy outcomes were inconsistent across ALS studies.
CONCLUSION
Based on safety and efficacy results, we do not support using DPS to manage respiratory failure in patients with ALS or cervical spine injury.

BACKGROUND
Patient-ventilator asynchrony (PVA) is a common problem in patients undergoing invasive mechanical ventilation (MV) in the intensive care unit (ICU), and may accelerate lung injury and diaphragm mis-contraction. The impact of PVA on clinical outcomes has not been systematically evaluated. Effective interventions (except for closed-loop ventilation) for reducing PVA are not well established.
METHODS
We performed a systematic review and meta-analysis to investigate the impact of PVA on clinical outcomes in patients undergoing MV (Part A) and the effectiveness of interventions for patients undergoing MV except for closed-loop ventilation (Part B). We searched the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, ClinicalTrials.gov, and WHO-ICTRP until August 2020. In Part A, we defined asynchrony index (AI) ≥ 10 or ineffective triggering index (ITI) ≥ 10 as high PVA. We compared patients having high PVA with those having low PVA.
RESULTS
Eight studies in Part A and eight trials in Part B fulfilled the eligibility criteria. In Part A, five studies were related to the AI and three studies were related to the ITI. High PVA may be associated with longer duration of mechanical ventilation (mean difference, 5.16 days; 95% confidence interval [CI], 2.38 to 7.94; n = 8; certainty of evidence [CoE], low), higher ICU mortality (odds ratio [OR], 2.73; 95% CI 1.76 to 4.24; n = 6; CoE, low), and higher hospital mortality (OR, 1.94; 95% CI 1.14 to 3.30; n = 5; CoE, low). In Part B, interventions involving MV mode, tidal volume, and pressure-support level were associated with reduced PVA. Sedation protocol, sedation depth, and sedation with dexmedetomidine rather than propofol were also associated with reduced PVA.
CONCLUSIONS
PVA may be associated with longer MV duration, higher ICU mortality, and higher hospital mortality. Physicians may consider monitoring PVA and adjusting ventilator settings and sedatives to reduce PVA. Further studies with adjustment for confounding factors are warranted to determine the impact of PVA on clinical outcomes.

Meta-Analysis
OBJECTIVE
Significant variations exist in the use of respiratory muscle ultrasound in intensive care with no society-level consensus on the optimal methodology. This systematic review aims to evaluate, synthesize, and compare the clinimetric properties of different image acquisition and analysis methodologies.
DATA SOURCES
Systematic search of five databases up to November 24, 2021.
STUDY SELECTION
Studies were included if they enrolled at least 50 adult ICU patients, reported respiratory muscle (diaphragm or intercostal) ultrasound measuring either echotexture, muscle thickness, thickening fraction, or excursion, and evaluated at least one clinimetric property. Two independent reviewers assessed titles, abstracts, and full text against eligibility.
DATA EXTRACTION
Study demographics, ultrasound methodologies, and clinimetric data.
DATA SYNTHESIS
Sixty studies, including 5,025 patients, were included with 39 studies contributing to meta-analyses. Most commonly measured was diaphragm thickness (DT) or diaphragm thickening fraction (DTF) using a linear transducer in B-mode, or diaphragm excursion (DE) using a curvilinear transducer in M-mode. There are significant variations in imaging methodology and acquisition across all studies. Inter- and intrarater measurement reliabilities were generally excellent, with the highest reliability reported for DT (ICC, 0.98; 95% CI, 0.94-0.99). Pooled data demonstrated acceptable to excellent accuracy for DT, DTF, and DE to predicting weaning outcome after 48 to 72 hours postextubation (DTF AUC, 0.79; 95% CI, 0.73-0.85). DT imaging was responsive to change over time. Only three eligible studies were available for intercostal muscles. Intercostal thickening fraction was shown to have excellent accuracy of predicting weaning outcome after 48-hour postextubation (AUC, 0.84; 95% CI, 0.78-0.91).
CONCLUSIONS
Diaphragm muscle ultrasound is reliable, valid, and responsive in ICU patients, but significant variation exists in the imaging acquisition and analysis methodologies. Future work should focus on developing standardized protocols for ultrasound imaging and consider further research into the role of intercostal muscle imaging.

The Effectiveness of Spinal, Diaphragmatic, and Specific Stabilization Exercise Manual Therapy and Respiratory-Related Interventions in Patients with Chronic Nonspecific Neck Pain: Systematic Review and Meta-Analysis.
Patients with nonspecific chronic neck pain (NSCNP) exhibit respiratory dysfunction. This systematic review aimed to analyze randomized controlled trials (RCTs) investigating the effect of spinal and/or diaphragmatic and/or specific stabilization exercise manual therapy and/or respiratory exercises on musculoskeletal and respiratory diagnostic outcomes in patients with NSCNP. A systematic search and selection of RCTs was performed in three scientific databases (Pubmed, Scopus, and Physiotherapy Evidence Database (PEDro)) and one search engine (Google Scholar) from inception to April 2022. Relevant studies published in the English language were extracted, evaluated, and independently rated for methodological quality (PEDro scale). The quality of the evidence was assessed with the GRADE approach. Out of 1089 studies collected in total, 1073 were excluded (i.e., did not meet the inclusion criteria or were duplicates). Sixteen RCTs were finally included, rated on 5.62/10 (PEDro score) on average for methodological quality. Overall, there was sparse evidence that spinal and/or diaphragmatic manual therapy and/or trunk stabilization exercises and/or respiratory exercises significantly improved pain, disability, and respiratory outcomes in patients with NSCNP immediately post-treatment. However, the clinical heterogeneity between studies was significant, and the level of certainty of the evidence was low to very low. More, high-quality RCTs are required, contributing to the holistic diagnostic monitoring and management of patients with NSCNP.

Review
Bronchogenic cysts (BC) are congenital abnormalities that occur most commonly within the mediastinum, and rarely occur within the diaphragm. We present the 21st case of an intradiaphragmatic bronchogenic cyst in the English literature, and review all previous published cases. Analysis includes presenting clinical symptoms, relevant radiologic studies, surgical approaches to resection, and management of the diaphragm, among other relevant data. These lesions should remain on the differential diagnosis in cases of unusual masses in the region of the diaphragm.
