Meta-Analysis Review
BACKGROUND
Surgical approach is the most effective treatment for primary spontaneous pneumothorax. The two most widely adopted surgical methods are mechanical abrasion and apical pleurectomy, in addition to bullectomy. We performed a systematic review and meta-analysis to examine which technique is superior in treating primary spontaneous pneumothorax.
METHODS
PubMed, MEDLINE and EMBASE databases were searched for studies published between January 2000 to September 2022 comparing mechanical abrasion and apical pleurectomy for treatment of primary spontaneous pneumothorax. The primary outcome was pneumothorax recurrence. Secondary outcomes included post-operative chest tube duration, hospital length of stay, operative time and intra-operative of blood loss.
RESULTS
Eight studies were eligible for inclusion involving 1,613 patients. There was no difference in the rate of pneumothorax recurrence between pleural abrasion and pleurectomy (RR: 1.34; 95% CI: 0.94 to 1.92). However, pleural abrasion led to shorter hospital length of stay (MD: -0.25; 95% CI: -0.51 to 0.00), post-operative chest tube duration (MD: -0.30; 95% CI: -0.56 to -0.03), operative time (MD: -13.00; 95% CI -15.07 to 10.92) and less surgical blood loss (MD: -17.77; 95% CI: -24.36 to -11.18).
CONCLUSION
Pleural abrasion leads to less perioperative patient burden and shorter hospital length of stay without compromising the rate of pneumothorax recurrence when compared to pleurectomy. Thus, pleural abrasion is a reasonable first choice surgical procedure for management of primary spontaneous pneumothorax.

Review
BACKGROUND
Several types of pressure sources, including underwater bubble devices, mechanical ventilators, and the Infant Flow Driver, are used for providing continuous positive airway pressure (CPAP) to preterm infants with respiratory distress. It is unclear whether the use of bubble CPAP versus other pressure sources is associated with lower rates of CPAP treatment failure, or mortality and other morbidity. OBJECTIVES: To assess the benefits and harms of bubble CPAP versus other pressure sources (mechanical ventilators or Infant Flow Driver) for reducing treatment failure and associated morbidity and mortality in newborn preterm infants with or at risk of respiratory distress.
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2023, Issue 1); MEDLINE (1946 to 6 January 2023), Embase (1974 to 6 January 2023), Maternity & Infant Care Database (1971 to 6 January 2023), and the Cumulative Index to Nursing and Allied Health Literature (1982 to 6 January 2023). We searched clinical trials databases and the reference lists of retrieved articles.
SELECTION CRITERIA
We included randomised controlled trials comparing bubble CPAP with other pressure sources (mechanical ventilators or Infant Flow Driver) for the delivery of nasal CPAP to preterm infants.
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methods. Two review authors separately evaluated trial quality, extracted data, and synthesised effect estimates using risk ratio (RR), risk difference (RD), and mean difference. We used the GRADE approach to assess the certainty of the evidence for effects on treatment failure, all-cause mortality, neurodevelopmental impairment, pneumothorax, moderate-severe nasal trauma, and bronchopulmonary dysplasia.
MAIN RESULTS
We included 15 trials involving a total of 1437 infants. All trials were small (median number of participants 88). The methods used to generate the randomisation sequence and ensure allocation concealment were unclear in about half of the trial reports. Lack of measures to blind caregivers or investigators was a potential source of bias in all of the included trials. The trials took place during the past 25 years in care facilities internationally, predominantly in India (five trials) and Iran (four trials). The studied pressure sources were commercially available bubble CPAP devices versus a variety of mechanical ventilator (11 trials) or Infant Flow Driver (4 trials) devices. Meta-analyses suggest that the use of bubble CPAP compared with mechanical ventilator or Infant Flow Driver CPAP may reduce the rate of treatment failure (RR 0.76, 95% confidence interval (CI) 0.60 to 0.95; (I² = 31%); RD -0.05, 95% CI -0.10 to -0.01; number needed to treat for an additional beneficial outcome 20, 95% CI 10 to 100; 13 trials, 1230 infants; low certainty evidence). The type of pressure source may not affect mortality prior to hospital discharge (RR 0.93, 95% CI 0.64 to 1.36 (I² = 0%); RD -0.01, 95% CI -0.04 to 0.02; 10 trials, 1189 infants; low certainty evidence). No data were available on neurodevelopmental impairment. Meta-analysis suggests that the pressure source may not affect the risk of pneumothorax (RR 0.73, 95% CI 0.40 to 1.34 (I² = 0%); RD -0.01, 95% CI -0.03 to 0.01; 14 trials, 1340 infants; low certainty evidence). Bubble CPAP likely increases the risk of moderate-severe nasal injury (RR 2.29, 95% CI 1.37 to 3.82 (I² = 17%); RD 0.07, 95% CI 0.03 to 0.11; number needed to treat for an additional harmful outcome 14, 95% CI 9 to 33; 8 trials, 753 infants; moderate certainty evidence). The pressure source may not affect the risk of bronchopulmonary dysplasia (RR 0.76, 95% CI 0.53 to 1.10 (I² = 0%); RD -0.04, 95% CI -0.09 to 0.01; 7 trials, 603 infants; low certainty evidence). AUTHORS' CONCLUSIONS: Given the low level of certainty about the effects of bubble CPAP versus other pressure sources on the risk of treatment failure and most associated morbidity and mortality for preterm infants, further large, high-quality trials are needed to provide evidence of sufficient validity and applicability to inform context- and setting-relevant policy and practice.

Meta-Analysis
To quantitatively analyze the risk factors for air embolism following computed tomography (CT)-guided percutaneous transthoracic needle biopsy (PTNB) and qualitatively review their characteristics. The databases of PubMed, Embase, Web of Science, Wanfang Data, VIP information, and China National Knowledge Infrastructure were searched on January 4, 2021, for studies reporting the occurrence of air embolisms following CT-guided PTNB. After study selection, data extraction, and quality assessment, the characteristics of the included cases were qualitatively and quantitatively analyzed. A total of 154 cases of air embolism following CT-guided PTNB were reported. The reported incidence was 0.06% to 4.80%, and 35 (22.73%) patients were asymptomatic. An unconscious or unresponsive state was the most common symptom (29.87%). Air was most commonly found in the left ventricle (44.81%), and 104 (67.53%) patients recovered without sequelae. Air location ( < 0.001), emphysema ( = 0.061), and cough ( = 0.076) were associated with clinical symptoms. Air location ( = 0.015) and symptoms ( < 0.001) were significantly associated with prognosis. Lesion location [odds ratio (OR): 1.85, = 0.017], lesion subtype (OR: 3.78, = 0.01), pneumothorax (OR: 2.16, = 0.003), hemorrhage (OR: 3.20, < 0.001), and lesions located above the left atrium (OR: 4.35, = 0.042) were significant risk factors for air embolism. Based on the current evidence, a subsolid lesion, being located in the lower lobe, the presence of pneumothorax or hemorrhage, and lesions located above the left atrium were significant risk factors for air embolism.

Review
Pectus excavatum is a congenital chest wall deformity, commonly identified in early childhood, creating a "sunken chest" appearance. Over time, the deformity can worsen, thus impacting cardiopulmonary function and creating significant body image disturbance in patients. The Nuss procedure is a minimally invasive technique in which a curved steel bar is introduced underneath the sternum through small bilateral thoracic incisions to correct the deformity. Most studies regarding the procedure to date focus on outcomes and complications in pediatric patients, however, few studies discuss these results in adult patients. This systematic review aims to analyze common complications and outcomes in patients over the age of 18 who have not undergone any prior intervention for pectus excavatum. The most common complications experienced in adult patients were displacement of the implanted steel bar, infection of the surgical site, pneumothorax, pleural effusion, and chronic postoperative pain. Reoperation was common in patients with a displacement of the bar, chronic pain, and bleeding. Additionally, adult patients routinely required a higher number of steel bars to be placed to correct the deformity. Despite evidence that the rate of complications increases with age, the majority of adult patients in our included studies were satisfied with the outcome of the procedure with indications of improved self-image and reduced preoperative symptoms such as dyspnea on exertion, palpitations, chest pain, and depression.

Review
BACKGROUND
Intraventricular haemorrhage (IVH) is a major complication of preterm birth. Large haemorrhages are associated with a high risk of disability and hydrocephalus. Instability of blood pressure and cerebral blood in the newborn flow are postulated as causative factors. Another mechanism may involve reperfusion damage from oxygen free radicals. It has been suggested that phenobarbital stabilises blood pressure and may protect against free radicals. This is an update of a review first published in 2001 and updated in 2007 and 2013.
OBJECTIVES
To assess the benefits and harms of the postnatal administration of phenobarbital in preterm infants at risk of developing IVH compared to control (i.e. no intervention or placebo).
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL), Medline, Embase, CINAHL and clinical trial registries in January 2022. A new, more sensitive search strategy was developed, and searches were conducted without date limits. SELECTION CRITERIA: We included randomised controlled trials (RCTs) or quasi-RCTs in which phenobarbital was given within the first 24 hours of life to preterm infants identified as being at risk of IVH because of gestational age below 34 weeks, birth weight below 1500 g or respiratory failure. Phenobarbital was compared to no intervention or placebo. We excluded infants with serious congenital malformations.
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methods. Our primary outcomes were all grades of IVH and severe IVH (i.e. grade III and IV); secondary outcomes were ventricular dilation or hydrocephalus, hypotension, pneumothorax, hypercapnia, acidosis, mechanical ventilation, neurodevelopmental impairment and death. We used GRADE to assess the certainty of the evidence for each outcome.
MAIN RESULTS
We included 10 RCTs (792 infants). The evidence suggests that phenobarbital results in little to no difference in the incidence of IVH of any grade compared with control (risk ratio (RR) 1.00, 95% confidence interval (CI) 0.84 to 1.19; risk difference (RD) 0.00, 95% CI -0.06 to 0.07; I² for RD = 65%; 10 RCTs, 792 participants; low certainty evidence) and in severe IVH (RR 0.88, 95% CI 0.64 to 1.21; 10 RCTs, 792 participants; low certainty evidence). The evidence is very uncertain about the effect of phenobarbital on posthaemorrhagic ventricular dilation or hydrocephalus (RR 0.62, 95% CI 0.31 to 1.26; 4 RCTs, 271 participants; very low certainty evidence), mild neurodevelopmental impairment (RR 0.57, 95% CI 0.15 to 2.17; 1RCT, 101 participants; very low certainty evidence), and severe neurodevelopmental impairment (RR 1.12, 95% CI 0.44 to 2.82; 2 RCTs, 153 participants; very low certainty evidence). Phenobarbital may result in little to no difference in death before discharge (RR 0.88, 95% CI 0.64 to 1.21; 9 RCTs, 740 participants; low certainty evidence) and mortality during study period (RR 0.98, 95% CI 0.72 to 1.33; 10 RCTs, 792 participants; low certainty evidence) compared with control. We identified no ongoing trials.
AUTHORS' CONCLUSIONS
The evidence suggests that phenobarbital results in little to no difference in the incidence of IVH (any grade or severe) compared with control (i.e. no intervention or placebo). The evidence is very uncertain about the effects of phenobarbital on ventricular dilation or hydrocephalus and on neurodevelopmental impairment. The evidence suggests that phenobarbital results in little to no difference in death before discharge and all deaths during the study period compared with control. Since 1993, no randomised studies have been published on phenobarbital for the prevention of IVH in preterm infants, and no trials are ongoing. The effects of postnatal phenobarbital might be assessed in infants with both neonatal seizures and IVH, in both randomised and observational studies. The assessment of benefits and harms should include long-term outcomes.

International Journal of Hyperthermia :... 2023To evaluate the safety and clinical efficacy of image-guided radiofrequency ablation (RFA) in patients exhibiting adrenal metastatic tumors (AMTs). (Meta-Analysis)
Meta-Analysis
PURPOSE
To evaluate the safety and clinical efficacy of image-guided radiofrequency ablation (RFA) in patients exhibiting adrenal metastatic tumors (AMTs).
METHODS
The PubMed, Web of Science, and Wanfang databases were searched for relevant studies published as of November 2022, and study results were pooled for subsequent analysis. The endpoints of this meta-analysis included primary and secondary technical success, local hemorrhage, pneumothorax, hypertensive crisis, local recurrence, and 1- and 3-year overall survival (OS) rates.
RESULTS
This analysis incorporated 11 studies enrolling 351 patients that underwent RFA treatment for 373 AMTs. The pooled primary and secondary technical success, local hemorrhage, pneumothorax, hypertensive crisis, local recurrence, and 1- and 3-year OS rates in these patients were 84%, 91%, 4%, 6%, 7%, 19%, 82%, and 46%, respectively. The 1-year OS ( = 75.2%, = 0.003) and 3-year OS ( = 81.4%, = 0.001) endpoints were subject to significant heterogeneity. Subgroup analyses suggested that primary technical success rates were < 80% in patients with tumors exhibiting a mean diameter ≥ 4 cm. Guidance type and tumor size had no impact on a hypertensive crisis or local recurrence rates.
CONCLUSIONS
These data indicate that image-guided RFA represents a safe and effective means of treating AMTs.

INTRODUCTION
Imaging-guided percutaneous ablation (PA) is commonly employed for the treatment of patients diagnosed with adrenal metastasis (AM), but comprehensive analyses are essential to validate the efficacy and safety of this approach.
AIM
The present meta-analysis was designed to evaluate the safety, efficacy, and long-term outcomes associated with the imaging-guided PA treatment of AM.
MATERIAL AND METHODS
Relevant studies in the PubMed, Embase, and Wanfang databases published as of June 2022 were identified, and pooled endpoint analyses were performed with Stata 12.0.
RESULTS
This meta-analysis included 15 studies. Overall, the respective pooled primary technical success, secondary technical success, local hemorrhage, pneumothorax, hypertension crisis, local recurrence, 1-year overall survival (OS), and 3-year OS rates in study participants were 88%, 93%, 3%, 6%, 6%, 19%, 80%, and 46%. High levels of heterogeneity were evident for the 1-year OS (I = 79.6%) and 3-year OS endpoints (I = 67.1%), but meta-regression analyses failed to identify predictors of these OS rates. Low heterogeneity was observed for subgroups of patients who had undergone cryoablation (I = 0%) or patients with multiple primary cancers (I = 0%) with respect to 1-year OS. Similarly, low heterogeneity for the 3-year OS endpoint was detected in subgroups of patients who had undergone cryoablation (I = 0%), ultrasound-guided PA (I = 0%), individuals with AMs secondary to hepatocellular carcinoma (I = 0%), and patients with multiple primary cancers (I = 0%).
CONCLUSIONS
These results suggest imaging-guided PA to be a safe and effective treatment for AM associated with satisfactory long-term patient outcomes.

INTRODUCTION
The Ehlers-Danlos syndromes (EDS) comprise a group of inherited connective tissue disorders presenting with variable fragility to skin, soft tissue, and certain internal organs, which can cause significant complications, particularly arterial rupture, bowel perforation and joint difficulties. Currently, there are 14 proposed subtypes of EDS, with all except one subtype (hypermobile EDS) having an identified genetic etiology. An understanding of the extracutaneous features and complications within each subtype is key to maximizing clinical care and reducing the risk of further complications.
METHODS
A systematic review of EDS-related extracutaneous features and complications was undertaken.
RESULTS
We identified 839 EDS cases that met the inclusion criteria. We noted a high prevalence of joint hypermobility amongst kyphoscoliotic (39/39, 100%), spondylodysplastic (24/25, 96.0%), and hypermobile (153/160, 95.6%) EDS subtypes. The most common musculoskeletal complications were decreased bone density (39/43, 90.7%), joint pain (217/270, 80.4%), and hypotonia/weakness (79/140, 56.4%). Vascular EDS presented with cerebrovascular events (25/153, 16.3%), aneurysm (77/245, 31.4%), arterial dissection/rupture (89/250, 35.5%), and pneumothorax/hemothorax. Chronic pain was the most common miscellaneous complication, disproportionately affecting hypermobile EDS patients (139/157, 88.5%). Hypermobile EDS cases also presented with chronic fatigue (61/63, 96.8%) and gastrointestinal complications (57/63, 90.5%). Neuropsychiatric complications were noted in almost all subtypes.
DISCUSSION
Understanding the extracutaneous features and complications of each EDS subtype may help diagnose and treat EDS prior to the development of substantial comorbidities and/or additional complications.

Meta-Analysis Review
UNLABELLED
Initial management of inadequate adaptation to extrauterine life relies on non-invasive respiratory support. Two types of devices are available: fixed pressure devices (FPD; T-pieces or ventilators) and hand driven pressure devices (HDPD; self- or flow-inflating bags). This systematic review and meta-analysis aims to compare clinical outcomes after neonatal resuscitation according to device type.
METHODS
Four databases were searched from inception to 2022, January. Search strategies included Mesh/Emtree terms as well as free language without any restriction. Randomized, quasi-randomized studies and prospective cohorts comparing the use of the two types of devices in neonatal resuscitation were included.
RESULTS
Nine studies recruiting 3621 newborns were included: 5 RCTs, 2 RCTs with interventions bundles and 2 prospective cohorts. Meta-analysis of the 5 RCTs demonstrated significant reductions in bronchopulmonary dysplasia (RR0,68[0,48-0,96]-NNT 31) and other respiratory outcomes: intubation in the delivery room (RR0,72[0,58-0,88]-NNT 13,4), mechanical ventilation requirements (RR0,81[0,67-0,96]-NNT 17) and duration (MD-1,54 days[-3,03- -0,05]), need for surfactant (RR0,79[0,64-0,96]-NNT 7,3). The overall analysis found a lower mortality in the FPD group (OR0,57[0,47-0,69]-NNT 12,7) and confirmed decreases in intubation, surfactant requirement and mechanical ventilation rates (OR 0,56[0,40-0,79]- NNT7,5; OR 0,67[0,55-0,82]-NNT10,7 and OR0,58[0,42-0,80]- NNT 7,4 respectively). The risk of cystic periventricular leukomalacia (cPVL) decreased significantly with FPD (OR0.59[0.41-0.85]-NNT 27). Pneumothorax rates were similar (OR0.82[0.44-1.52]).
CONCLUSION AND RELEVANCE
Resuscitation at birth with FPD improves respiratory transition and decreases BPD with a very low to moderate certainty of evidence. There is suggestion of decreases in mortality and cPVL. Further studies are still needed to confirm those results.

BACKGROUND
Lymphangioleiomyomatosis (LAM) is a rare disease involving multiple systems, which is divided into sporadic LAM (S-LAM) and tuberous sclerosis complex-LAM, mostly affecting women who are in childbearing age stage. Data on male patients are limited and scattered. Therefore, it is necessary to conduct a systematic review to investigate the clinical features, diagnosis, treatment, and outcomes of LAM in male.
METHODS
We performed a literature review by searching for all the published reported cases of LAM in male during the past 35 years (April 1986-October 2021).
RESULTS
36 male patients described in 26 references were included in this article. The median age of onset was 34 years (interquartile range: 1-79). The most common initial manifestations were cough, dyspnea, respite, and hemoptysis, with pulmonary complications such as pneumothorax and chylothorax. Five patients (13.9%) were asymptomatic at admission. Nearly half of the 36 male patients had thin-walled air-filled cysts that were visible throughout both lungs. Considering the abovementioned atypical clinical features, misdiagnosis was committed in 8 patients (22.2%). In addition, patients with tuberous sclerosis complex lymphangioleiomyomatosis often have no pulmonary manifestations at onset but present multiple extrapulmonary manifestations and have higher rates of renal angiomyolipomas than patients with S-LAM (P < 0.01). Eventually, 4 patients with S-LAM eventually died.
CONCLUSION
Physicians should increase the awareness of LAM in male. Early monitoring of various systems should be recommended to ensure early management and active follow-up. Tuberous sclerosis complex patients should immediately be tracked for the onset of LAM disease to improve prognosis.
