RESUMEN
INTRODUCTION: Intracranial fungal infections' (IcFIs) varying clinical manifestations lead to difficulties in diagnosis and treatment. African populations are disproportionately affected by the high burden of the disease. There is a lack of clarity as to the diagnostic and treatment modalities employed across the continent. In this review, we aim to detail the management, and outcome of IcFIs across Africa. METHODS: This scoping review was conducted using the Arksey and O'Malley framework. MEDLINE, EMBASE, Cochrane Library, African Index Medicus, and African Journals Online were searched for relevant articles from database inception to August 10th, 2021. The Preferred Reporting Items for Systematic Review and Meta-Analysis extension for Scoping Reviews guidelines were used to report the findings of the review. RESULTS: Of the 5,779 records identified, 131 articles were included. The mean age was 35.6 years, and the majority (56.4%) were males. The majority (n = 8,433/8,693, 97.0%) of IcFIs presented as a meningitis, the most common communicable predisposing factor of IcFIs was HIV/AIDS (n = 7,815/8,693, 89.9%), and the most common non-communicable risk factor was diabetes mellitus (n = 32/8,693, 0.4%). Cryptococcus species was the most common (n = 8,428/8,693, 97.0%) causative organism. The most commonly used diagnostic modality was cerebrospinal (CSF) cultures (n = 4,390/6,830, 64.3%) for diffuse IcFIs, and MRI imaging (n = 12/30, 40%) for focal IcFIs. The most common treatment modality was medical management with antifungals only (n = 4,481/8,693, 51.6%). The most commonly used antifungal agent in paediatric, and adult patients was amphotericin B and fluconazole dual therapy (51.5% vs 44.9%). The overall mortality rate was high (n = 3,475/7,493, 46.3%), and similar for both adult and paediatric patients (47.8% vs 42.1%). CONCLUSION: Most IcFIs occurred in immunosuppressed individuals, and despite the new diagnostic techniques, CSF culture was mostly used in Africa. Antifungals regimens used was similar between children and adults. The outcome of IcFIs in Africa was poor for both paediatric and adult patients.

INTRODUCTION: While right ventricular pacing (RVP) is the conventional temporary pacing modality used for transcatheter aortic valve replacement (TAVR), this approach possesses inherent risks and procedural challenges. We aim to assess and compare the safety and efficacy of left ventricular pacing (LVP) and RVP during TAVR and balloon aortic valvuloplasty (BAV). METHODS: Following PRISMA guidelines, a comprehensive literature search was conducted in four databases from inception to December 15th, 2023. We included observational studies and clinical trials comparing LVP with RVP during TAVR and BAV procedures. Primary outcomes included short-term mortality, mortality due to cardiac tamponade, and procedural complications including bleeding, vascular complications, and cardiac tamponade. Secondary outcomes comprised procedure duration and length of hospital stay. RESULTS: Five studies involving 830 patients with RVP and 1577 with LVP were included. Short-term mortality was significantly higher in the RVP group (RR 2.32, 95% CI: [1.37-3.93], P = .002), as was the incidence of cardiac tamponade (RR 2.19, 95% CI: [1.11-4.32], P = .02). LVP demonstrated shorter hospital stays (MD = 1.34 d, 95% CI: [0.90, 1.78], P < .001) and reduced procedure duration (MD = 7.75 min, 95% CI: [5.08, 10.41], P < .00001) compared to RVP. New pacemaker implantation was higher in the RVP group (RR 2.23, 95% CI: [1.14, 4.39], P = .02). CONCLUSION: LVP during TAVR and BAV emerges a safer alternative to RVP, offering reduced mortality, hospital stays, and procedure durations.
RESUMEN
BACKGROUND: Hepatocellular carcinoma (HCC) is the most common type of liver cancer, accounting for 90% of cases worldwide and a significant contributor to cancer-related deaths. This study comprehensively compares the safety and efficacy of laparoscopic liver resection (LLR) versus laparoscopic or percutaneous radiofrequency ablation (LRFA or PRFA) in patients with early and small HCC. METHODS: We systematically searched Cochrane Library, PubMed, Scopus, and Web of Science databases to include studies comparing LLR versus LRFA or PRFA in patients with early HCC meets the Milan criteria (defined as solitary nodule < 5 cm or three nodules ≤ 3 cm with no extrahepatic spread or vascular invasion). Pooled results were examined for overall survival, disease-free survival, recurrence-free survival, local, intrahepatic and extrahepatic recurrence rates, and complications. We conducted subgroup analyses based on the type of RFA. Meta-regression analyzed the association between overall survival, local recurrence, and various factors. The quality of the included studies was assessed using the Newcastle-Ottawa Scale. We analyzed the data using the R (v.4.3.0) programming language and the "meta" package of RStudio software. RESULTS: We included 19 observational studies, compromising 3756 patients. LLR showed higher 5-year overall survival compared to RFA (RR = 1.17, 95% CI [1.06, 1.3], P > 0.01). Our subgroup analysis showed that LLR had higher 5-year survival than PRFA (RR = 1.15, 95% CI [1.02, 1.31], P = 0.03); however, there was no significant difference between LLR and LRFA (RR = 1.26, 95% CI [0.98, 1.63], P = 0.07). LLR was associated with higher disease-free survival) RR = 1.19, 95% CI [1.05, 1.35], P < 0.01; RR = 1.61, 95% CI [1.31, 1.98], P < 0.01(and recurrence-free survival) RR = 1.21, 95% CI [1.09, 1.35], P < 0.01; RR = 1.45, 95% CI [1.15, 1.84], P < 0.01(at 1 and 3 years. LLR was associated with lower local (RR = 0.28, 95% CI [0.16, 0.47], P < 0.01) and intrahepatic recurrence (RR = 0.7, 95% CI [0.5, 0.97], P = 0.03) than RFA. However, complications were significantly higher with LLR (RR = 2.01, 95% CI [1.51, 2.68], P < 0.01). Our meta-regression analysis showed that younger patients had higher risk for local recurrence (P = 0.008), while age wasn't significantly linked to overall survival (P = 0.25). Other covariates like total bilirubin, alpha-fetoprotein levels, and tumor size also showed no significant associations with either overall survival or local recurrence. CONCLUSION: LLR offers improved long-term outcomes and lower recurrence rates than PRFA. However, no significant distinctions were observed between LRFA and LLR in overall survival, recurrence-free survival, and local recurrence. More robust well-designed RCTs are essential to validate our findings.

BACKGROUND: Diabetic ketoacidosis (DKA) is a potentially life-threatening complication of type 1 diabetes mellitus (T1DM) that has increased during the COVID-19 pandemic. This study will not only shed light on such life-threatening complications but also be a step to increase the awareness of healthcare providers about such complications in the upcoming pandemic waves and increased dependence on telemedicine. Thus, we aimed to further investigate the increase of DKA in pediatrics. METHODS: PubMed, Web of Science, and Scopus were broadly searched for studies assessing the incidence of DKA in pediatrics during the COVID-19 pandemic. RESULTS: Our study included 24 papers with a total of 124,597 children with diabetes. A statistically significant increase occurred in the risk of DKA among newly diagnosed T1DM patients during the pandemic (RR 1.41; 95% CI 1.19, 1.67; p < 0.01; I2 = 86%), especially in the severe form of DKA (RR 1.66: 95% CI 1.3, 2.11) when compared to before. CONCLUSION: DKA in newly diagnosed children with T1DM has increased during the pandemic and presented with a severe form. This may reflect that COVID-19 may have contributed not only to the development but also the severity of DKA. IMPACT: Diabetic ketoacidosis (DKA) is a life-threatening complication of type 1 diabetes mellitus (T1DM) that has increased during the COVID-19 pandemic. Our study included 25 papers with a total of 124,597 children with diabetes. A statistically significant increase occurred in the risk of DKA among newly diagnosed T1DM patients during the pandemic. Our findings reflect that COVID-19 may have an altered presentation in T1DM and can be related to DKA severity.

INTRODUCTION: This study aimed to compare the long-term outcomes in a propensity matched population receiving total arterial grafting (TAG) and multiple arterial grafts (MAG) in addition to saphenous vein graft (SVG) following multivessel coronary artery bypass grafting requiring at least three distal anastomoses. METHODS: In this retrospective study, 655 patients from two centers met the inclusion criteria and were divided into two groups: TAG group (n = 231) and MAG + SVG group (n = 424). Propensity score matching was performed resulting in 231 pairs. RESULTS: No significant differences were observed between both groups in terms of early outcomes. Survival probabilities at 5, 10, and 15 y were 89.1% versus 94.2%, 76.2% versus 76.1%, and 66.7% versus 69.8% in the TAG and MAG + SVG groups, respectively (hazard ratio stratified on matched pairs: 0.90; 95% confidence interval [0.45-1.77]; P = 0.754). Freedom from major adverse cardiac and cerebral events (MACCE) in the matched cohort did not show any significant difference between both groups. Probabilities at 5, 10, and 15 y were 82.7% versus 85.6%, 62.2% versus 75.3%, and 48.8% versus 59.5% in the TAG and MAG + SVG groups, respectively (hazard ratio stratified on matched pairs: 1.12; 95% confidence interval [0.65-1.92]; P = 0.679). Subgroup analyses of the matched cohort showed no significant difference between TAR with three arterial conduits compared to TAR with two arterial conduits with sequential grafting and MAG + SVG in terms of long-term survival and freedom from MACCE. CONCLUSIONS: Multiple arterial revascularizations in addition to SVG may yield comparable long-term outcomes in terms of survival and freedom from MACCE compared to total arterial revascularization.

Chronic hepatitis B (CHB) infection is a risk factor for hepatocellular carcinoma (HCC). Previous studies showed that elevated levels of Hepatitis B Virus (HBV) DNA and HBsAg are associated with increased HCC risk in patients with chronic HBV infection. Multiple studies showed that high levels of HBV DNA and Hepatitis B Surface Antigen (HBsAg) are associated with higher HCC risk in CHB patients. Patients treated with antiviral therapy may have undetectable or low levels of HBV DNA and HBsAg loss. However, HCC may develop in some patients with low-level HBV DNA and HBsAg seroconversion. In this study, we evaluated the role of HBcrAg in predicting HBV related HCC development. We searched PubMed, Scopus, and Web of Science databases using keywords (hepatitis B core-related antigen, hepatocellular carcinoma, liver neoplasm, hepatocellular and hepatic cancer, to identify studies assessing serum level of HBcrAg in patients with CHB and HCC. The search resulted in 184 studies. Seven studies were included: Four of which were retrospective cohort studies, and the rest were prospective cohort, case controls. Six of them reported a higher HBcrAg positivity rate in the HCC group when compared with the HBV DNA assay, yet with similar hazard ratio (HR) in predicting the incidence of HCC. However, four studies found that HBcrAg positivity was an independent risk factor for HCC development with a HR ranging from 3.27 to 7.05. HBV-related HCC has many proposed biomarkers in its prediction, yet our findings revealed HBcrAg to may have superiority over other biomarkers. High quality studies with bigger sample size research is needed to understand the potential role of HBcrAg in CHB induced HCC.

Tenecteplase (TNK) is a promising candidate to replace alteplase as the standard of care for acute ischemic stroke (AIS); however, the optimal dosage is still to be investigated. Therefore, we aim to evaluate the safety and efficacy of TNK versus alteplase and to investigate the optimal TNK dosage. A systematic review, pairwise, and network meta-analysis synthesizing randomized controlled trials (RCTs) from WOS, SCOPUS, EMBASE, and PubMed until July 26th, 2022. We used the risk ratio (RR) for dichotomous outcomes presented with the corresponding 95% confidence interval (CI). We registered our protocol in PROSPERO with ID: CRD42022352038. Nine RCTs with a total of 3,707 patients were included. TNK significantly led to complete recanalization (RR: 1.27 with 95% CI [1.02, 1.57], P = 0.03); however, we found no difference regarding early neurological improvement (RR: 1.07 with 95% CI [0.94, 1.21], P = 0.33) and excellent neurological recovery (RR: 1.03 with 95% CI [0.96, 1.10], P = 0.42). Also, TNK was similar to alteplase regarding mortality (RR: 0.99 with 95% CI [0.82, 1.18], P = 0.88), intracranial haemorrhage (RR: 1.00 with 95% CI [0.85, 1.18], P = 0.99), and parenchymal hematoma (RR: 1.13 with 95% CI [0.83, 1.54], P = 0.44). TNK in the dose of 0.25 mg is a viable candidate to displace alteplase as the standard of care in patients with an AIS within 4.5 h of presentation due to its better rate of early neurological recovery and non-inferiority in terms of safety outcomes. However, the evidence regarding TNK's role in AIS presenting after 4.5 h from symptoms onset, wake-up stroke, and minor stroke/TIA is still lacking, necessitating further double-blinded pragmatic RCTs in this regard.

BACKGROUND: A critical and unmet therapeutic need is the prompt and reliable exclusion of acute myocardial infarction (AMI), which would allow for prompt discharge from the emergency department. High-sensitivity troponin (HS-TnT) combined with copeptin has been proposed to expedite the diagnostic exclusion of AMI in addition to its predictive usefulness in the intermediate and long-term outcomes of AMI. The European Society of Cardiology recommends the Global Registry of Acute Coronary Events (GRACE) as a prognostic score to manage acute coronary syndrome (ACS) without ST segment elevation. The purpose of this study was to compare the diagnostic accuracy of HS-TnT combined with copeptin in ruling out AMI compared to HS-TnT alone. By combining a low GRACE score (108) with negative HS-TnT (14 ng/L) and copeptin (14 pmol/L), non-ST and ACS were reliably ruled out, including non-ST segment elevation MI and unstable angina. RESULTS: The present research included nine studies with a total of 13,232 participants. The negative predictive value (NPV) for copeptin and HS-TnT was found to be slightly higher in combination (62-99%) than for HS-TnT alone (60-99%). The sensitivity of copeptin ranged from 0% to 100%, with a pooled sensitivity of 0.79 (CI 95% 0.76, 0.82). The specificity of copeptin ranged from 13% to 100%, with a pooled specificity of 0.89 (CI 95% 0.85, 0.91), a pooled positive likelihood ratio (PLR) of 9.86 (CI 95% 4.42, 22.02), and a pooled negative likelihood ratio (NLR) of 0.08. (95% CI 0.01, 0.44). CONCLUSIONS: The use of combined negative copeptin and highly sensitive troponin testing in low-to-intermediate risk patients with suspected acute coronary syndrome resulted in a quick discharge with a safe and rapid rule out of non-ST + ACS.

BACKGROUND AND OBJECTIVE: Double sequential external defibrillation (DSED) and vector-change defibrillation (VCD) have been suggested to enhance clinical outcomes for patients with ventricular fibrillation (VF) refractory of standard defibrillation (SD). Therefore, this network meta-analysis aims to evaluate the comparative efficacy of DSED, VCD, and SD for refractory VF. METHODS: A systematic review and network meta-analysis synthesizing randomized controlled trials (RCTs) and comparative observational studies retrieved from PubMed, EMBASE, WOS, SCOPUS, and Cochrane through November 15th, 2022. R software netmeta and netrank package (R version 4.2.0) and meta-insight software were used to pool dichotomous outcomes using odds ratio (OR) presented with the corresponding confidence interval (CI). Our protocol was prospectively published in PROSPERO with ID: CRD42022378533. RESULTS: We included seven studies with a total of 1632 participants. DSED was similar to SD in survival to hospital discharge (OR: 1.14 with 95% CI [0.55, 2.83]), favorable neurological outcome (modified Rankin scale ≤2 or cerebral performance category ≤2) (OR: 1.35 with 95% CI [0.46, 3.99]), and return of spontaneous circulation (ROSC) (OR: 0.81 with 95% CI [0.43; 1.5]). In addition, VCD was similar to SD in survival to hospital discharge (OR: 1.12 with 95% CI [0.27, 4.57]), favorable neurological outcome (OR: 1.01 with 95% CI [0.18, 5.75]), and ROSC (OR: 0.88 with 95% CI [0.24; 3.15]). CONCLUSION: Double sequential external defibrillation and VCD were not associated with enhanced outcomes in patients with refractory VF out-of-hospital cardiac arrest, compared to SD. However, the current evidence is still inconclusive, warranting further large-scale RCTs.

BACKGROUND: Sildenafil was first prescribed for angina pectoris and then for erectile dysfunction from its effects on vascular smooth muscle relaxation and vasodilatation. Recently, sildenafil has been proposed for congenital heart diseases induced pulmonary hypertension, which constitutes a huge burden on children's health and can attribute to fatal complications due to presence of unoxygenated blood in the systemic circulation. Therefore, our meta-analysis aims to further investigate the safety and efficacy of sildenafil on children population. METHODS: We searched the following electronic databases: PubMed, Cochrane CENTRAL, WOS, Embase, and Scopus from inception to April 20th, 2022. Randomized controlled trials that assess the efficacy of using sildenafil in comparison to a placebo or any other vasodilator drug were eligible for inclusion. The inverse variance method was used to pool study effect estimates using the random effect model. Effect sizes are provided in the form of mean difference (MD) with 95% confidence intervals (CI). RESULTS: Our study included 14 studies with (n = 849 children) with a mean age of 7.9 months old. Sildenafil showed a statistically significant decrease over placebo in mean and systolic pulmonary artery pressure (PAP) with MD -7.42 (95%CI [-13.13, -1.71], P = 0.01) and -8.02 (95%CI [-11.16, -4.88], P < 0.0001), respectively. Sildenafil revealed a decrease in mean aortic pressure and pulmonary artery/aortic pressure ratio over placebo with MD -0.34 (95%CI [-2.42, 1.73], P = 0.75) and MD -0.10 (95%CI [-0.11, -0.09], P < 0.00001), respectively. Regarding post corrective operations parameters, sildenafil had a statistically significant lower mechanical ventilation time, intensive care unit stay, and hospital stay over placebo with MD -19.43 (95%CI [-31.04, -7.81], s = 0.001), MD -34.85 (95%CI [-50.84, -18.87], P < 0.00001), and MD -41.87 (95%CI [-79.41, -4.33], P = 0.03), respectively. Nevertheless, no difference in mortality rates between sildenafil and placebo with OR 0.25 (95%CI 0.05, 1.30], P = 0.10) or tadalafil with OR 1 (95%CI 0.06, 17.12], P = 1). CONCLUSION: Sildenafil is a well-tolerated treatment in congenital heart diseases induced pulmonary hypertension, as it has proven its efficacy not only in lowering both PAP mean and systolic but also in reducing the ventilation time, intensive care unit and hospital stay with no difference observed regarding mortality rates.

OBJECTIVES: For patients with aortic stenosis, transcatheter aortic valve replacement (TAVR) offers a less invasive treatment modality than conventional surgical valve replacement. Although the surgery is performed traditionally under general anesthesia (GA), recent studies have described success with TAVR using local anesthesia (LA) and/or conscious sedation. The study authors performed a pairwise meta-analysis to compare the clinical outcomes of TAVR based on operative anesthesia management. DESIGN: A random effects pairwise meta-analysis via the Mantel-Haenszel method. SETTING: Not applicable, as this is a meta-analysis. PARTICIPANTS: No individual patient data were used. INTERVENTIONS: Not applicable, as this is a meta-analysis. MEASUREMENTS AND MAIN RESULTS: The authors comprehensively searched the PubMed, Embase, and Cochrane databases to identify studies comparing TAVR performed using LA or GA. Outcomes were pooled as risk ratios (RR) or standard mean differences (SMD) and their 95% CIs. The authors' pooled analysis included 14,388 patients from 40 studies (7,754 LA; 6,634 GA). Compared to GA TAVR, LA TAVR was associated with significantly lower rates of 30-day mortality (RR 0.69; p < 0.01) and stroke (RR 0.78; p = 0.02). Additionally, LA TAVR patients had lower rates of 30-day major and/or life-threatening bleeding (RR 0.64; p = 0.01), 30-day major vascular complications (RR 0.76; p = 0.02), and long-term mortality (RR 0.75; p = 0.009). No significant difference was seen between the 2 groups for a 30-day paravalvular leak (RR 0.88, p = 0.12). CONCLUSIONS: Transcatheter aortic valve replacement performed using LA is associated with lower rates of adverse clinical outcomes, including 30-day mortality and stroke. No difference was seen between the 2 groups for a 30-day paravalvular leak. These results support the use of minimally invasive forms of TAVR without GA.

OBJECTIVES: Patients with chronic kidney disease (CKD) are susceptible to changes in zinc homeostasis through anorexia and dietary restrictions, as well as hemodialysis (HD). Changes in zinc homeostasis might predispose CKD and HD patients to specific adverse effects, including erythropoietin-resistant anemia, oxidative stress, atherosclerosis, and cardiovascular disease. Because serum zinc levels are rarely measured in CKD and HD patients, zinc supplementations do not represent a routine therapy for CKD and dialysis patients. Therefore, in this meta-analysis, we aimed to assess serum zinc levels in CKD and HD patients compared with healthy controls (HC). In addition, we investigated whether HD affects serum zinc levels by comparing serum zinc levels in HD versus CKD patients and comparing serum zinc pre- versus post-HD. DESIGN AND METHODS: A comprehensive search of databases was conducted to identify either observational studies or randomized trials that assessed serum zinc levels in either CKD and/or HD patients in comparison to HC. We conducted a random-effects meta-analysis. RESULTS: Our meta-analysis included 42 studies with a total of 4,161 participants, of whom 460 were CKD patients, 2,047 were HD patients, and 1,654 were HCs. Both CKD and HD patients showed lower serum zinc levels compared with HC (mean difference = -22.86 µg/dL, 95% CI -33.25 to -12.46; mean difference = -13.64 µg/dL, 95% CI -21.47 to -53.80, respectively). CKD and HD patients showed no significant difference in serum zinc levels (mean difference = 15.39, 95% CI -8.91 to 39.68). Pre-HD serum zinc levels were significantly lower than those post-HD (mean difference = -7.51 µg/dL, 95% CI -14.24 to -0.78). CONCLUSION: In the current study, the serum zinc levels were lower in CKD and HD patients compared to HCs and appears to be more common than reported in daily clinical practice. It may be beneficial to assess serum zinc levels in CKD and HD patients. More research on zinc in kidney disease is encouraged.

BACKGROUND: Death from stroke is linked to cancer due to its pathogenesis and side effects of treatment. Despite this, guidelines regarding identifying cancer patients at the highest risk of mortality from stroke are unclear. AIMS: To determine which cancer subtypes are associated with higher risk of death from stroke. METHODS: The National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program was used to obtain data regarding patients with cancer who died of a stroke. We calculated standardized mortality ratios (SMRs) using SEER*Stat software, version 8.4.0.1. RESULTS: Out of 6,136,803 patients with cancer, 57,523 (0.9%) died from stroke, and this rate was higher than general population (SMR= 1.05, 95%CI [1.04-1.06]). Deaths due to stroke decreased across years, from 24,280 deaths between 2000-2004 to 4,903 deaths between 2015-2019. Of the 57,523 stroke deaths, greatest numbers were observed in cancers of the prostate (n=11,761, 20.4%), breast (n=8,946, 15.5%), colon and rectum (n=7,401, 12.8%), and lung and bronchus (n=4,376, 7.6%). Patients with colon and rectum cancers (SMR= 1.08 95%CI [1.06-1.11]), lung and bronchus cancers (SMR=1.70 95%CI [1.65-1.75]) had a greater rate of death from stroke compared to the general population. CONCLUSION: The risk of death from stroke in cancer patients is significantly higher than in the general population. Patients with colorectal cancer and lung and bronchus cancer are at higher risk of death by stroke compared to the general population.

OBJECTIVES: To evaluate the analgesic and anti-haemorrhagic efficacy of platelet-rich plasma (PRP) among patients undergoing tonsillectomy. DESIGN: A systematic review and meta-analysis of randomised controlled trials (RCTs). SETTING: PubMed, Scopus, Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL) and Google Scholar databases were screened from inception until July 2021, and updated in December 2021. PARTICIPANTS: Patients undergoing tonsillectomy. MAIN OUTCOME MEASURES: The efficacy endpoints of postoperative pain and haemorrhage were summarised as standardised mean difference (SMD) and risk ratio (RR), respectively, with 95% confidence interval (CI). RESULTS: Seven RCTs Seven RCTs were analysed, comprising a total of 392 patients. Risk of bias evaluation showed an overall high risk in one RCT, low risk in four RCTs and some concerns in two RCTs. The pooled results revealed that the mean postoperative pain score was significantly reduced in favour of the PRP group compared with the control group (SMD = -1.38, 95% CI [-1.91, -0.85], p < 0.001). Subgroup analysis showed the effect estimate was statistically significant for early postoperative pain (Day 0 to Day 3), without substantial difference between both groups on late postoperative pain (Days 5 and 7). Moreover, the rate of postoperative haemorrhage was significantly reduced in favour of the PRP group compared with the control group (RR = 0.16, 95% CI [0.05, 0.50], p = 0.001). Subgroup analysis showed the effect estimate was statistically significant for the rate of primary and secondary haemorrhage. CONCLUSION: PRP was associated with significant reduction in postoperative pain and haemorrhage among patients undergoing tonsillectomy.

Sutureless/rapid-deployment (SURD) valves are options different from the stented prostheses included in the pivotal trials comparing surgical aortic valve replacement (AVR) and transcatheter aortic valve implantation (TAVI). We performed a meta-analysis with reconstructed time-to-event data of matched studies published by November 2021 to compare SURD-AVR and TAVI. Primary endpoints were 30-day mortality and overall survival in the follow-up. Secondary endpoints included: 30-day stroke, acute kidney injury (AKI), major bleeding, permanent pacemaker implantation (PPI), paravalvular leak (PVL), prosthesis-patient mismatch (PPM), postoperative aortic valve area (AVA), and mean gradients. Ten studies met our eligibility criteria, including a total of 5134 patients (2567 underwent SURD-AVR and 2567 underwent TAVI). Pooled risk of 30-day mortality did not favor any group (odds ratio [OR]: 0.69; 95% confidence interval [CI]: 0.31-1.53; p = 0.360). Patients undergoing SURD-AVR had lower risk of PVL (OR: 0.09; 95% CI: 0.05-0.17; p < 0.001). No statistically significant differences were observed for 30-day stroke, AKI, major bleeding, PPI, PPM, and postoperative AVA. In the follow-up, we observed a higher risk of mortality (hazard ratio: 1.74; 95% CI: 1.26-2.40; p < 0.001) with TAVI. Patients who underwent SURD-AVR experienced better survival, however, the interpretation of these results warrant caution due to the fact that SURD-AVR patients tended to be younger than TAVI patients. Structural heart surgeons and interventional cardiologists should consider initial risk and life expectancy when referring patients for one approach over the other.

Representing 10%-25% of the primary cardiac neoplasms, primary malignant cardiac tumors (PMCT) have a poor prognosis, yet with rare incidence. Constituting more than 50% of the PMCT, cardiac sarcoma has increased not only in incidence over the past five decades but also in severity. Patients with PMCTs, especially sarcomas, have the worst prognosis when compared with other cardiac or extracardiac tumors. This retrospective study was performed using SEER*stat software, latest version 8.3.9.2(5) by accessing seer 18 registries plus data (excl AK) Nov 2020 Sub (2000-2018) for standard mortality ratio (SMR). A total of 235 patients were identified of whom 49.4% were females. Most of our patients were Stage 4 (n = 81) and distant in location (n = 92). The most common treatment method was tumor-directed surgery (n = 164), chemotherapy (n = 146), and radiotherapy (n = 55). Furthermore, other associated cancers with cardiac sarcoma were rare, with ten cases with lung and bronchus cancer (SMR: 37.95, 95% confidence interval [CI]: 18.2, 69.8), four with bone and joints (SMR: 1726.05, 95% CI: 470.2, 4419.3). During a 5-year follow-up, 235 patients died primarily due to cardiac sarcoma (n = 182, 77.4%), other cancers (n = 34, 14.4%), and other noncancerous causes (n = 19, 8%), while the noncancerous causes were attributed mainly to cardiovascular diseases (n = 4, 21%, SMR: 4.95, 95% CI: 1.35, 12.67), septicemia (n = 2, 10.5%, SMR: 41.23, 95% CI: 4.99, 148.95).

OBJECTIVES: To compare outcomes of complete transcatheter (TAVI plus PCI) versus complete surgical (SAVR plus CABG) approach to treat patients with aortic stenosis (AS) and concomitant coronary artery disease (CAD). METHODS: Study-level meta-analysis with reconstructed time-to-event data including studies published by November 2021. The primary endpoints were 30-day mortality, overall survival, and major adverse cardiovascular and cerebrovascular events (MACCE). The secondary endpoints were 30-day stroke, myocardial infarction, and permanent pacemaker implantation (PPI); in-hospital major vascular events and acute kidney injury (AKI). RESULTS: Eight studies met our eligibility criteria, including a total of 33,286 patients (3448 for TAVI plus PCI and 29,838 for SAVR plus CABG). The pooled risk of 30-day mortality was lower for TAVI plus PCI (OR 0.63; 95% CI 0.51-0.80; p < .001). Patients undergoing TAVI plus PCI had lower risk of in-hospital AKI (OR 0.49; 95% CI 0.28-0.85; p = .01), however, higher risk of major vascular events (OR 7.33; 95% CI 1.80-29.85; p = .005) and higher risk of PPI (OR 2.96; 95% CI 1.80-4.85; p < .001). No statistically significant difference was observed for myocardial infarction and stroke between the groups. In the follow-up analyses, we observed a higher risk of mortality (HR 1.64, 95% CI 1.36-1.96, p < .001) and MACCE with TAVI plus PCI (HR 1.35 (95% CI 1.08-1.69, p = .009). CONCLUSION: Patients who undergo TAVI plus PCI (in comparison with SAVR plus CABG) initially experience lower rates of in-hospital death and AKI; however, they experience significantly lower survival rates and more MACCE at 5-year follow up. Structural heart surgeons and interventional cardiologists should consider these aspects when referring patients for one approach or the other.

BACKGROUND: Valve infective endocarditis (IE) is a potentially life-threatening condition that affects patients' livelihoods. Current surgical options in mitral valve IE include mitral valve repair (MVr) or replacement (MVR). While each procedure boasts its merits, doubt remains as to which type of surgery is superior. METHODS: We searched PubMed, Scopus, Web of Science, and Cochrane literature databases for studies comparing MVR and MVr in mitral valve IE. Any randomized controlled trial (RCT) or observational studies that compare MVR vs. MVr in mitral valve IE were eligible. Our dichotomous outcomes were extracted in the form of event and total, and risk and hazard ratio (RR)(HR) with 95% confidence interval (CI) and were pooled and calculated using RevMan 5.0. RESULTS: Our study included 23 studies with a total population of 11,802 patients. Compared to MVR, MVr had statistically significant lower risks of both early mortality with RR [0.44; 95% CI, 0.38-0.51; p < 0.001] and long-term follow-up mortality with HR [0.70; 95% CI, 0.58-0.85; p = 0.0004]. Moreover, MVr was associated with a statistically significant lower risk of IE recurrence with RR [0.43; 95% CI, 0.32-0.58; p < 0.001]; however, no statistically significant differences between both groups in terms of re-operations with RR [0.83; 95% CI, 0.41-1.67; p = 0.60]. CONCLUSION: Our results suggest that MVr was superior in terms of in-hospital mortality, long-term survival, and risk of recurrence without significance in valve reoperation. Therefore, MVr is appropriate as a primary treatment choice and should be considered whenever possible in most IE patients.

INTRODUCTION: Deciding whether to perform coronary artery bypass grafting (CABG) alone or in combination with mitral valve repair is a common dilemma encountered by surgeons when treating patients with ischemic mitral regurgitation, a common condition related to coronary artery disease. Although ischemic mitral regurgitation after CABG has been linked to unfavorable results, the benefits of including mitral valve repair are still unknown. This discrepancy led us to undertake a systematic review and meta-analysis to determine whether combining CABG with mitral valve surgery leads to better clinical results than CABG alone. EVIDENCE ACQUISITION: Studies comparing the results of CABG versus CABG with mitral valve replacement were searched in the databases of PubMed and Google Scholar. There were six randomized clinical trials included in this study. EVIDENCE SYNTHESIS: We analyzed 852 patients' data. There were no significant variations between patients who acquired CABG alone or CABG+(MVR) in terms of their risk of death at one year, stroke, atrial fibrillation, or hospitalization for heart failure. For recurrent/residual mitral regurgitation; it revealed an RR=5.42, 95% CI, 0.77 to 37.98, and a P-value of =0.065. According to the analysis of study heterogeneity, no apparent heterogeneity was identified in the outcomes of death after one year, stroke, atrial fibrillation, or hospitalization for heart failure. However, the outcome of recurrent or residual mitral regurgitation showed significant variation (I2=66%). CONCLUSIONS: Patients who underwent CABG alone versus CABG plus MVR did not differ significantly from one another. However, the comparison of CABG alone with CABG plus MVR underlines the need for customized treatment plans based on the unique characteristics of each patient.
