Meta-Analysis
OBJECTIVE
Despite the establishment of transcatheter closure as the treatment of choice in adults with secundum atrial septal defects (ASDs), the effectiveness of this approach in the elderly is disputed. This systematic review and meta-analysis aims to explore the impact of transcatheter ASD closure in patients ≥60 years old.
METHODS
We systematically searched four major electronic databases (PubMed, CENTRAL (Cochrane Central Register of Controlled Trials), Scopus and Web of Science), ClinicalTrials.gov, article references and grey literature. Primary outcomes were the right ventricular end-diastolic diameter (RVEDD) and the New York Heart Association functional class change, whereas secondary outcomes included systolic pulmonary arterial pressure (sPAP), left ventricular end-diastolic diameter (LVEDD), brain natriuretic peptide (BNP), tricuspid valve regurgitation (TR) change, as well as the rate of atrial arrhythmias and all-cause mortality.
RESULTS
In total, 18 single-arm cohorts comprising 1184 patients were included. RVEDD was reduced after ASD closure (standardised mean difference (SMD) -0.9, 95% CI -1.2 to -0.7). Elderly patients had 9.5 times higher odds of being asymptomatic after ASD closure (95% CI 5.06 to 17.79). Furthermore, ASD closure improved sPAP (mean difference (MD) -10.8, 95% CI -14.6 to -7), LVEDD (SMD 0.8, 95% CI 0.7 to 1.0), TR severity (OR 0.39, 95% CI 0.25 to 0.60) and BNP (MD -68.3, 95% CI -114.4 to -22.1). There was a neutral effect of ASD closure on atrial arrhythmias.
CONCLUSIONS
Transcatheter ASD closure is beneficial for the elderly population since it improves functional capacity, biventricular dimensions, pulmonary pressures, TR severity and BNP. However, the incidence of atrial arrhythmias did not change significantly after the intervention.

Review
BACKGROUND
Valve-sparing aortic procedures, including the David and Yacoub procedures, have emerged as the dominant approaches in aortic aneurysm surgery, preserving the native aortic valve and thereby conferring significant prognostic benefits to the patient. Over the years, these procedures have also shown promise in patients with bicuspid valve-related aortopathy. This systematic review and meta-analysis presents the most up-to-date data on perioperative outcomes, freedom from secondary reoperation, and freedom from mortality for bicuspid valve patients undergoing valve-sparing aortic operations.
METHODS
The methods for this systematic review and meta-analysis adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. Four databases were searched, ultimately yielding 19 papers for inclusion, using appropriate search terminology. Meta-analysis using proportions or means, as appropriate, were applied. Kaplan-Meier curves were digitized and aggregated using previously validated techniques.
RESULTS
A total of 1,159 patients were included. Males accounted for 87.4% of the cohort. The mean age of the cohort was 44.9 years. The mean aortic root diameter was estimated to be 46.3 mm, with an estimated range from 38 to 54 mm. Thirty-day mortality rate was estimated to be 1.7%. Eighty-five percent of patients in this series received the David approach, with the remainder receiving the Yacoub approach. Overall, there was low heterogeneity observed for the mean length of intensive care stay, while high heterogeneity was observed for the other remaining variables of interest. Kaplan-Meier survival estimation at 5, 10, and 15 years was 96%, 90%, and 87%, respectively. Kaplan-Meier freedom from secondary reoperation at 5, 10, and 15 years was 96%, 91%, and 88%, respectively.
CONCLUSIONS
This review demonstrates the durability and safety of the David and Yacoub valve-sparing procedures across long-term follow-up in bicuspid aortic valve patients. These procedures offer significant freedom from mortality and secondary reoperations on the aorta and valve and will likely continue to demonstrate excellent results into the future. There is a clear transition towards the David procedure, with the bulk of contemporary literature publishing on this technique.

The efficacy and safety of sacubitril/valsartan compared with ACEI/ARB in the treatment of heart failure following acute myocardial infarction: a systematic review and meta-analysis of randomized controlled trials.
To systematically assess the efficacy and safety of sacubitril/valsartan (SV) by comparison with angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) for the treatment of heart failure caused by acute myocardial infarction (HF-AMI) based on current randomized controlled trials (RCTs). Several electronic databases were searched up to 27 May 2023. Primary endpoints were the efficacy including the left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), N-terminal pro-B type natriuretic peptide (NT-proBNP) and 6-min walk test (6MWT) and secondary endpoints were the safety including the major adverse cardiovascular event (MACE) and adverse reaction (AE). A total of 14 RCTs were included and all patients were from China. Among included 1,991 patients, 997 patients received SVs and 994 patients received ACEIs/ARBs. The pooled results demonstrated that patients in the SV group showed significantly better efficacy representing as increased LVEF [weighted mean difference (WMD): 4.43%, 95% confidence interval (CI): 2.84%-6.02%, < 0.001] and 6MWT (WMD: 30.84 m, 95% CI: 25.65 m-36.03 m, < 0.001) and decreased LVEDD (WMD: -3.24 mm, 95% CI: -4.96 mm ∼ -1.52 mm, < 0.001) and NT-proBNP (WMD: -188.12 pg/mL, 95% CI: -246.75 pg/mL ∼ 129.49 pg/mL, < 0.001), which was also verified by subgroup analysis based on the history of percutaneous coronary intervention (PCI). Besides, the SV group showed significantly lower incidence rate of MACE [relative risk (RR): 0.60, 95% CI: 0.47-0.75, < 0.001] and patients receiving SVs in the non-PCI group also showed lower incidence of AE (RR: 0.38, 95% CI: 0.20-0.71, = 0.002). For the treatment of HF-AMI, SV is more effective and safer than ACEI/ARB based on current evidence, but more high-quality RCTs are still needed to verify above findings.

OBJECTIVE
To identify and critically appraise literature on true brachial artery aneurysm, exploring its demographic characteristics, aetiologies, clinical manifestations and different methods of repair along with complication rates to determine future treatment strategies.
METHODS
The systematic review was conducted at Liaquat National Hospital, Karachi, from September 30, 2021, to November 30, 2022, in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Literature was searched on MEDLINE, EMBASE and Cochrane databases for relevant studies in English language or with English translation published till May 31, 2022. The key words used for the search were "brachial artery aneurysm". Data was noted on a proforma and was subjected to descriptive analysis.
RESULTS
Of 113 articles, 6 (5.3%) were retrospective studies, 7 (6.1%) were case series and 100 (88.4%) were case reports. The total number of patients involved was 157 with mean age 43.1±23.4 years (range: 2 months to 84 years). The gender was mentioned for 152(96.8%) patients; 111(73%) males and 41(27%) females. The mean diameter of true brachial artery aneurysm was 36.2 ±17.5mm and 106(67.5%) patients presented with localised swelling, 65(41.4%) with pain, 41(26.1%) with distal ischaemic symptoms, and 28(17.8%) with median nerve compression. True brachial artery aneurysms were more common in renal failure patients having a history of arteriovenous fistula creation in the affected limb and were on immunosuppressant drugs due to renal transplant 81(51.5%). Less common causes included primary/idiopathic 27(17.1%), trauma 13(8.2%), connective tissue disorders 8(5%) and vasculitis 7(4.5%). The treatment of choice was aneurysmectomy in 142(90.4%) cases, with revascularisation of limb primarily with reversed great saphenous vein graft 79(50.3 %), followed by end-to-end anastomosis of brachial artery 17(10.8%) and synthetic grafting 17(10.8%). Endovascular intervention was performed in 6(3.8%) cases to exclude true brachial artery aneurysm, and to re-establish adequate blood flow to the associated limb.
CONCLUSION
True brachial artery aneurysm, although a rarity, may lead to significant neurological and vascular problems if ignored. Arteriovenous fistula and immunosuppression are identified as two significant risk factors in the development of true brachial artery aneurysm. Therefore, an effective long-term follow up in renal failure patients is recommended to prevent its complications. Open surgical repair has been the most preferred mode of treatment, but further significant studies are needed to explore and compare different modes of surgical intervention, like open versus endovascular, to plan future treatment strategies.

Meta-Analysis
Calcified coronary plaque (CCP) represents a challenging scenario for interventional cardiologists. Stent underexpansion (SU), often associated with CCP, can predispose to stent thrombosis and in-stent restenosis. To date, SU with heavily CCP can be addressed using very high-/high-pressure noncompliant balloons, off-label rotational atherectomy/orbital atherectomy, excimer laser atherectomy, and intravascular lithotripsy (IVL). In this meta-analysis, we investigated the success rate of IVL for the treatment of SU because of CCP. Studies and case-based experiences reporting on the use of IVL strategy for treatment of SU were included. The primary end point was IVL strategy success, defined as the adequate expansion of the underexpanded stent. A metanalysis was performed for the main focuses to calculate the proportions of procedural success rates with corresponding 95% confidence intervals (CIs). Random-effects models weighted by inverse variance were used because of clinical heterogeneity. This meta-analysis included 13 studies with 354 patients. The mean age was 71.3 years (95% CI 64.9 to 73.1), and 77% (95% CI 71.2% to 82.4%) were male. The mean follow-up time was 2.6 months (95% CI 1 to 15.3). Strategy success was seen in 88.7% (95% CI 82.3 to 95.1) of patients. The mean minimal stent area was reported in 6 studies, the pre-IVL value was 3.4 mm (95% CI 3 to 3.8), and the post-IVL value was 6.9 mm (95% CI 6.5 to 7.4). The mean diameter stenosis (percentage) was reported in 7 studies, the pre-IVL value was 69.4% (95% CI 60.7 to 78.2), and the post-IVL value was 14.6% (95% CI 11.1 to 18). The rate of intraprocedural complications was 1.6% (95% CI 0.3 to 2.9). In conclusion, the "stent-through" IVL plaque modification technique is a safe tool to treat SU caused by CCP, with a high success rate and a very low incidence of complications.

Review
Circumscribed choroidal hemangioma (CCH) is a sort of non-malignant hamartomatous tumor that occurs in the choroidal layer of the eye. It is a rare condition that affects people between their second and fourth decades of life, leading to significant deterioration of vision. One of the most catastrophic consequences of CCH is exudative retinal detachment (ERD), which has a severe impact on vision. This review aims to comprehensively assess the safety and efficacy of photodynamic therapy (PDT) using verteporfin as a therapeutic approach. Using the eligibility criteria, we analyzed the findings of 18 published articles from PubMed, Web of Science, Scopus, and Cochrane. The standard PDT protocol was used in all included studies, except two (one used half-dose, the other one used the double-dose) with an average of 1-2 sessions. PDT induced substantial tumor regression, with a mean thickness range from 0 to 2.3 mm. However, this contrasted with a previous study that reported a thickness of 3.46 mm as an indication of PDT failure. The mean tumor diameter varied from 4.8 mm to total tumor flattening. A suboptimal effect with a mean diameter ranging from 6mm to 8mm was found in two clinical studies. Significant improvement in vision was observed during the last follow-up, ranging from a normalization of Best Corrected Visual Acuity (BCVA) 20/20 to 20/80; counting finger vision persisted in two patients even after treatment. PDT successfully achieved complete subretinal fluid (SRF) resolution in 14 studies and resolved ERD in nine articles. Most studies did not report serious adverse events, but some reported macular atrophy, microcystic degeneration of the retina, transient visual disturbances, Retinal pigmented epithelium (RPE) metaplasia, and cystic degeneration of the retina. This systemic review demonstrated PDT's effectiveness and safety as a first-line management modality for CCH. Photodynamic therapy efficiently induced tumor regression, resulting in a notable reduction in both tumor diameter and thickness, with optimal efficacy to improve vision and resolution of the consequences of CCH, such as SRF and ERD.

Meta-Analysis Review
PURPOSE
Traumatic lumbar hernia (TLH) constitutes a protrusion of content through a defect in the posterior abdominal wall, as a result of injury. This rare entity has been described in limited number of cases.
METHODS
A systematic review of the literature was performed according to the meta-analysis of observational studies in epidemiology guidelines. The English literature from 1990 until 2021 was reviewed, using PubMed, EMBASE and Google Scholar bibliographic databases, to identify case reports and case series with patients that were diagnosed with TLH. For each eligible study, demographics, clinical presentation, hernia characteristics, preoperative imaging investigations, operation details, and postoperative data were extracted for assessment. Statistical analysis was performed on SPSS, version 20.0.
RESULTS
A total of 62 studies were included for review, with 164 patients with TLH. Mean age was (42.6 ± 14.3) years (47.6% males, 31.1% females, gender not specified in 35 cases). Mean diameter of hernia neck was (6.3 ± 3.1) cm, while the triangles of Petit and Grynfeltt were affected in 74.5% and 14.6%, respectively. Patients diagnosed in the emergency setting account for 54.2%, with CT scan establishing diagnosis in all but one case (97.7%). A delayed diagnosis was made in 45.8%, at a mean 1 year following trauma. Flank bulging (82.8%) and chronic back pain (34.3%) were the most frequent symptoms. In both delayed and acute group, open surgery (63.6% and 92.3%, respectively) was the preferred surgical approach. Postoperative complications were reported in 11.4% of acute and 15.0% of delayed patients. Hernia recurrence was 7%.
CONCLUSIONS
TLH is uncommon with 164 cases described since 1990. CT scan is the gold standard in diagnosis. Open surgery is generally the preferred approach, particularly in the emergency setting. Acute TLH can be treated either by primary suture repair or mesh, depending on the local conditions, whereas delayed cases usually require a mesh.

Meta-Analysis
Protective effects of melatonin against oxidative stress induced by metabolic disorders in the male reproductive system: a systematic review and meta-analysis of rodent models.
BACKGROUND
Male infertility is a multifaceted issue that has gained scientific interest due to its increasing rate. Studies have demonstrated that oxidative stress is involved in male infertility development. Furthermore, metabolic disorders, including obesity, diabetes, hypo- and hyperthyroidism, are risk factors for male infertility, and oxidative stress is believed to contribute to this association. Melatonin, functioning as an oxidative scavenger, may represent a promising therapeutic approach for the prevention and treatment of metabolic disorder-associated male infertility.
MATERIAL AND METHODS
We systematically searched three online databases (PubMed, Scopus, and Web of Science) for studies that evaluated the effects of melatonin therapy on metabolic disorders-induce infertility in male rodents. The favorable outcomes were histopathological parameters of testicular tissue, reproductive hormones, and markers of oxidative stress. Then, meta-analyses were done for each outcome. The results are reported as standardized mean difference (Cohen's d) and 95% confidence interval.
RESULTS
24 studies with 31 outcomes were included. Rats and mice were the subjects. Studies have employed obesity, diabetes, hypothyroidism, hyperthyroidism, hyperlipidemia, and food deprivation as metabolic disorders. To induce these disorders, a high-fat diet, high-fructose diet, leptin, streptozotocin, alloxan, carbimazole, and levothyroxine were used. The outcomes included histopathologic characteristics (abnormal sperm morphology, apoptotic cells, apoptotic index, Johnsen's testicular biopsy score, seminiferous epithelial height, tubular basement membrane thickness, tubular diameter, sperm count, and motility), weight-related measurements (absolute epididymis, testis, and body weight, body weight gain, epididymal adipose tissue weight, and relative testis to body weight), hormonal characteristics (androgen receptor expression, serum FSH, LH, and testosterone level), markers of oxidative stress (tissue and serum GPx and MDA activity, tissue CAT, GSH, and SOD activity), and exploratory outcomes (serum HDL, LDL, total cholesterol, triglyceride, and blood glucose level). The overall pooled effect sizes were statistically significant for all histopathological characteristics and some markers of oxidative stress.
CONCLUSIONS
Melatonin can reduce damage to male rodents' gonadal tissue and improve sperm count, motility, and morphology in metabolic diseases. Future clinical studies and randomized controlled trials are needed to evaluate the safety and effectiveness of melatonin for male infertility in patients with metabolic diseases.

The effects of statin therapy on aneurysm size, growth rate, and matrix metalloproteinases-9 levels in patients with aortic aneurysm: a systematic review and meta-analysis.
BACKGROUND
Aortic aneurysm enlargement over time causes rupture, which frequently results in death. The family of proteases known as matrix metalloproteinases (MMP) is assumed to be proteolytic activity involved in the growth of aortic aneurysms. Statins are pleiotropic lipid-lowering medications with anti-inflammatory action. Statins can lower aneurysmal enlargement and MMP secretion, according to a number of studies, however the evidence is still up for debate. The purpose of this study is to assess how statins affect aortic aneurysm patient's aneurysm diameter size, growth rate, and MMP-9 levels.
METHODS
From January 2000 to December 2022, electronic journal searches in PubMed, ScienceDirect, and Cochrane were conducted to discover papers evaluating the effects of statin treatment in patients with aortic aneurysm. Aneurysm diameter size, growth rate, and MMP-9 levels were the outcomes we were looking for. Meta-analyses were run on the included studies, and mean differences (MD) and 95% CIs were calculated with Review Manager v5.4.
RESULTS
Our analysis includes a total of ten research. Statin medication substantially reduced aneurysm diameter size by 0.30 mm (P = 0.04; MD - 0.30; 95% CI - 0.58 to - 0.01) and growth rate by 0.34 mm/year (P < 0.00001; MD - 0.34; 95% CI - 0.40 to - 0.29) compared to placebo. There was no significant change in MMP-9 concentrations between individuals with aortic aneurysm who took a statin and those who did not.
CONCLUSION
Overall, this meta-analysis demonstrates that statin medication is considerably helpful in reducing aneurysm diameter size and aneurysmal growth rate in individuals with aortic aneurysm.

Predicting the Invasiveness of Pulmonary Adenocarcinomas in Pure Ground-Glass Nodules Using the Nodule Diameter: A Systematic Review, Meta-Analysis, and Validation in an Independent Cohort.
The nodule diameter was commonly used to predict the invasiveness of pulmonary adenocarcinomas in pure ground-glass nodules (pGGNs). However, the diagnostic performance and optimal cut-off values were inconsistent. We conducted a meta-analysis to evaluate the diagnostic performance of the nodule diameter for predicting the invasiveness of pulmonary adenocarcinomas in pGGNs and validated the cut-off value of the diameter in an independent cohort. Relevant studies were searched through PubMed, MEDLINE, Embase, and the Cochrane Library, from inception until December 2022. The inclusion criteria comprised studies that evaluated the diagnostic accuracy of the nodule diameter to differentiate invasive adenocarcinomas (IAs) from non-invasive adenocarcinomas (non-IAs) in pGGNs. A bivariate mixed-effects regression model was used to obtain the diagnostic performance. Meta-regression analysis was performed to explore the heterogeneity. An independent sample of 220 pGGNs (82 IAs and 128 non-IAs) was enrolled as the validation cohort to evaluate the performance of the cut-off values. This meta-analysis finally included 16 studies and 2564 pGGNs (761 IAs and 1803 non-IAs). The pooled area under the curve, the sensitivity, and the specificity were 0.85 (95% confidence interval (CI), 0.82-0.88), 0.82 (95% CI, 0.78-0.86), and 0.73 (95% CI, 0.67-0.78). The diagnostic performance was affected by the measure of the diameter, the reconstruction matrix, and patient selection bias. Using the prespecified cut-off value of 10.4 mm for the mean diameter and 13.2 mm for the maximal diameter, the mean diameter showed higher sensitivity than the maximal diameter in the validation cohort (0.85 vs. 0.72, < 0.01), while there was no significant difference in specificity (0.83 vs. 0.86, = 0.13). The nodule diameter had adequate diagnostic performance in differentiating IAs from non-IAs in pGGNs and could be replicated in a validation cohort. The mean diameter with a cut-off value of 10.4 mm was recommended.
