The efficacy and safety of cabozantinib in patients with metastatic or advanced renal cell carcinoma: a systematic review and meta-analysis.

Background: Cabozantinib, a new first-line treatment for advanced renal cell carcinoma (aRCC), targets essential tyrosine kinases and outperforms the established comparator (sunitinib) in various efficacy outcomes. This systematic review and meta-analysis aimed to assess the efficacy and safety of cabozantinib compared to other aRCC treatments. Methods: Following PRISMA and Cochrane guidelines, our protocol was registered in PROSPERO. A systematic search, without date limits, was conducted on PubMed, Cochrane, Web of Science, and EMBASE until October 8, 2023. Data extraction encompassed study details, baseline information, and outcomes. Hazard ratios (HR) and risk ratios (RR) with 95% confidence intervals were employed for each outcome, and a random-effects model was applied to account for expected heterogeneity. Results: Three studies, encompassing 967 patients, were included in our analysis. In terms of efficacy, the pooled rate for overall survival significantly favored cabozantinib. However, in subgroup analyses, cabozantinib was only statistically superior to everolimus. For progression-free survival and tumor objective response rate, cabozantinib outperformed both everolimus and sunitinib. In adverse events, compared to sunitinib, cabozantinib exhibited inferiority in nearly all evaluated aspects, except for nausea and stomatitis, which showed no difference between the two groups. Conversely, it demonstrated a comparable risk profile with everolimus across various side effects. Conclusion: Cabozantinib shows significant efficacy in extending overall survival, progression-free survival, and tumor objective response rate despite a potentially higher risk of adverse events compared to sunitinib. These findings support cabozantinib as a first-line therapy for aRCC, either as an initial treatment or after prior VEGFR-targeted therapies.

Knowledge and skill level among non-healthcare providers regarding cardiopulmonary resuscitation (CPR) training in the Middle East (Arab countries): a systematic review and meta-analysis.

BACKGROUND: Effective education is considered by the American Heart Association (AHA) as a vital variable in improving outcomes of cardiac arrest. Studies have shown that the level of knowledge and attitude of non-healthcare providers towards resuscitation training varies widely across the globe. While some training methods and barriers to training have been discussed, the literature is still quite vague and unclear regarding resuscitation training, particularly in the Middle East. This study's focus on the efficacy of resuscitation training in this region of the world may help dictate how to better implement education initiatives aimed towards non-healthcare providers in developing countries. METHODOLOGY: A systematic review and meta-analysis were conducted on studies published from inception until March 2023. Observational studies assessing CPR knowledge and skills among non-healthcare workers in Arab countries were included. Data were extracted from PubMed, Cochrane Library, EMBASE, Web of Science, and Scopus. Data analysis was performed using Rstudio with a random effects model. RESULTS: 50 studies were included in this review and meta-analysis, revealing that 55% of participants had prior knowledge of CPR, while only 28% considered their knowledge sufficient. The majority (76%) supported mandatory CPR training, and 86% were willing to attend training if offered. This study found that prior knowledge of cardiopulmonary resuscitation (CPR) varied among populations. This meta-analysis also compiled results regarding CPR technique defined by correct compression to ventilation ratio, compression depth, compression rate, location of chest compression, and correct sequence. The overall results from this meta-analysis showed that, of these factors, compression rate and depth were the two factors that were most often administered incorrectly. In all, the results from this study demonstrated that CPR training in Arab countries was favorably viewed overall, with the majority of participants indicating both support for mandatory CPR training and general willingness to attend training if offered the opportunity. CONCLUSION: Given the overall positive view and willingness to learn CPR skills, healthcare policy makers should adopt a more comprehensive focus on strategies that enhance the accessibility and opportunity for CPR training for non-healthcare populations in Arab countries. Future training programs should implement strategies to highlight the ideal combination of compression rates and depth to learners to ensure correct and efficacious delivery of CPR with increased focus on the practical portion during refresher courses to promote retention.

Organ and function preservation in gastrointestinal cancer: Current and future perspectives on endoscopic ablation.

The escalating prevalence of gastrointestinal cancers underscores the urgency for transformative approaches. Current treatment costs amount to billions of dollars annually, combined with the risks and comorbidities associated with invasive surgery. This highlights the importance of less invasive alternatives with organ preservation being a central aspect of the treatment paradigm. The current standard of care typically involves neoadjuvant systemic therapy followed by surgical resection. There is a growing interest in organ preservation approaches by way of minimizing extensive surgical resections. Endoscopic ablation has proven to be useful in precursor lesions, as well as in palliative cases of unresectable disease. More recently, there has been an increase in reports on the utility of adjunct endoscopic ablative techniques for downstaging disease as well as contributing to non-surgical complete clinical response. This expansive field within endoscopic oncology holds great potential for advancing patient care. By addressing challenges, fostering collaboration, and embracing technological advancements, the gastrointestinal cancer treatment paradigm can shift towards a more sustainable and patient-centric future emphasizing organ and function preservation. This editorial examines the evolving landscape of endoscopic ablation strategies, emphasizing their potential to improve patient outcomes. We briefly review current applications of endoscopic ablation in the esophagus, stomach, duodenum, pancreas, bile ducts, and colon.

Efficacy and safety of extracorporeal membrane oxygenation for cardiogenic shock complicating myocardial infarction: a systematic review and meta-analysis.

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) has been presented as a potential therapeutic option for patients with cardiogenic shock complicating myocardial infarction (CS-MI). We aimed to investigate the efficacy and safety of ECMO in CS-MI. METHODS: A systematic review and meta-analysis synthesizing evidence from randomized controlled trials obtained from PubMed, Embase, Cochrane, Scopus, and Web of Science until September 2023. We used the random-effects model to report dichotomous outcomes using risk ratio and continuous outcomes using mean difference with a 95% confidence interval. Finally, we implemented a trial sequential analysis to evaluate the reliability of our results. RESULTS: We included four trials with 611 patients. No significant difference was observed between ECMO and standard care groups in 30-day mortality with pooled RR of 0.96 (95% CI: 0.81-1.13, p = 0.60), acute kidney injury (RR: 0.65, 95% CI: 0.41-1.03, p = 0.07), stroke (RR: 1.16, 95% CI: 0.38-3.57, p = 0.80), sepsis (RR: 1.06, 95% CI: 0.77-1.47, p = 0.71), pneumonia (RR: 0.99, 95% CI: 0.58-1.68, p = 0.96), and 30-day reinfarction (RR: 0.95, 95% CI: 0.25-3.60, p = 0.94). However, the ECMO group had higher bleeding events (RR: 2.07, 95% CI: 1.44-2.97, p < 0.0001). CONCLUSION: ECMO did not improve clinical outcomes compared to the standard of care in patients with CS-MI but increased the bleeding risk.

Impact of SGLT2 Inhibitors on Atrial Fibrillation Recurrence after Catheter Ablation in Type 2 Diabetes Mellitus: A Meta-Analysis of Reconstructed Kaplan-Meier Curves with Trial Sequential Analysis.

PURPOSE: The role of sodium-glucose cotransporter 2 inhibitors (SGLT2i) in managing cardiovascular outcomes in patients with type 2 diabetes mellitus (T2DM) is evolving. This meta-analysis seeks to explore the influence of SGLT2i on the recurrence of atrial fibrillation (AF) following catheter ablation (CA) in individuals with T2DM qualitatively and quantitatively. METHODS: A comprehensive literature search was conducted in electronic databases. Studies meeting predefined criteria were included. Individual patient data (IPD) were used from reconstructed time-to-event data to estimate hazard ratios (HRs) and 95% confidence intervals for AF recurrence. IPD meta-analysis was followed by a direct meta-analysis to assess the risk of AF recurrence. RESULTS: A total of five studies [one randomized controlled trial (RCT) and four cohort studies] were included in this study, and five studies were included in the qualitative analysis, while four studies comprising 1043 patients with T2DM were included in the quantitative analysis. The pooled Kaplan-Meier curve based on reconstructed data showed a significantly lower risk of AF recurrence in the SGLT2i group compared with all antidiabetic drugs (log-rank P = 0.00011) and dipeptidyl-peptidase IV inhibitors (DPP4i) (log-rank P = 0.01). Cox regression analysis showed consistent results. Direct meta-analysis showed that SGLT2i, compared with all antidiabetic medications (HR 0.57, 95% CI [0.44, 0.73], I2) and DPP4i (HR 0.41, 95% CI [0.24, 0.70], I2), was associated with a lower risk of AF recurrence. CONCLUSIONS: SGLT2i are associated with a reduced risk of AF recurrence after CA in patients with T2DM. These results suggest that SGLT2i is promising in improving clinical outcomes for this population.

The effect of Empagliflozin on echocardiographic parameters in diabetic patients after acute myocardial infarction: A systematic review and meta-analysis with trial sequential analysis.

Patients with diabetes mellitus (DM) are at higher risk of cardiovascular events, particularly acute myocardial infarction (MI). Sodium-glucose cotransporter 2 inhibitors (SGLT2i) can improve cardiac outcomes among heart failure individuals, however, the effects on acute myocardial infarction remain unclear. This meta-analysis investigates the impact of empagliflozin in diabetic patients following acute myocardial infarction. We comprehensively searched PubMed, Scopus, Cochrane, and Web of Science through August 10th, 2023. We included studies comparing empagliflozin versus placebo in diabetes patients with acute myocardial infarction. We used Revman to report the data as mean difference (MD) and 95% confidence interval (CI), and our effect size with a random effects model. Additionally, we performed Trial Sequential Analysis (TSA) to test the robustness of the results. The study protocol was published on PROSPERO with ID: CRD42023447733. Five studies with a total of 751 patients were included in our analysis. Empagliflozin was effective to improve LVEF% (MD: 1.80, 95% CI [0.50, 3.10], p = 0.007), left ventricular end-diastolic volume (LVEDV) (MD: -9.93, 95% CI [-16.07, -3.80], p = 0.002), and left ventricular end-systolic volume (LVESV) (MD: -7.91, 95% CI [-11.93, -3.88], p = 0.0001). However, there was no difference between empagliflozin and placebo groups in terms of NT-pro BNP (MD: - 136.59, 95% CI [-293.43, 20.25], p = 0.09), and HbA1c (MD: -0.72, 95% CI [-1.73, 0.29], p = 0.16). Additionally, empagliflozin did not prevent hospitalization due to heart failure (RR: 0.59, 95% CI [0.16, 2.24], p = 0.44, I-squared = 0%), and mortality (RR: 1.34, 95% CI [0.15,11.90], p = 0.79, I-squared = 25%). Empagliflozin initiation in diabetic patients following acute MI may improve echocardiographic parameters. However, empagliflozin might not be effective in heart failure prevention and optimal glycemic control in this patient population. Further large-scale trials are warranted to ascertain our findings.

Endoscopic ultrasound-guided gastrojejunostomy for benign gastric outlet obstruction (GOO): a retrospective analysis of patients and outcomes.

BACKGROUND AND STUDY AIMS: Endoscopic ultrasound-guided gastrojejunostomy (EUS-GJ) has been well utilized in treating malignant gastric outlet obstructions (GOO) given its efficacy and lower risk profile compared to surgery. However, its efficacy and potential for use in patients with benign GOO who are poor surgical candidates is not well documented. The aim of this study was to examine the role of EUS-GJ in treatment of benign GOO in select patients. PATIENTS AND METHODS: This is a single-center, open-label, retrospective descriptive study that included all consecutive patients undergoing EUS-GJ to treat benign causes of GOO. Direct antegrade and direct retrograde methods were utilized. RESULTS: A total of 18 patients were included, 38.9% female with an average age of 63.3 years. Extrinsic GOO was present in (10 of 18) 55.5% of patients and intrinsic etiology was present in (8 of 18) 45.5% of patients. Technical success was achieved in 100% (18 of 18) patients and clinical success was achieved in 94% (17 of 18) patients. In total, 13 patients had follow-up endoscopy, 2 patients were treated relatively recently in time, 1 patient was lost to follow-up, and 2 patients died of other chronic illnesses. Stents remained in place for a median of 286 days (range 88-1444 days). In patients whose stents were removed, 75% (3 of 4) had extrinsic etiologies of GOO. CONCLUSIONS: This study reports a favorable long-term patency with excellent technical and clinical success of EUS-GJ in patients with benign GOO. Despite the limitations of sample size and retrospective nature, it adds to the extremely limited literature of EUS-GJ in management of patients with benign GOO.

Coronavirus disease 19 (Covid-19): A comparative study of pattern of liver injury in adult patients in different waves of Covid-19 infection.

BACKGROUND AND STUDY AIMS: Liver dysfunction is a common manifestation of the COVID-19 infection. We aimed to study transaminase abnormalities through different waves of COVID-19 and their relations to disease severity or mortality. PATIENTS AND METHODS: A retrospective study included 521 Egyptian patients diagnosed with COVID-19. Data was retrieved from the medical records of patients who were admitted from April 2020 to October 2021 in Kasr Al-Ainy Hospitals, Cairo University, with categorization according to disease severity in correspondence to the four waves. RESULTS: The median age was lower in the first wave compared to other waves, with male predominance across all waves. The most commonly encountered comorbidity overall was hypertension, followed by diabetes mellitus. White blood cells, ferritin, and interleukin-6 showed the highest median values in the second wave, with significantly higher median C-reactive protein on day 1 in the first wave. Forty percent of the patients showed elevated hepatic transaminases on admission in four waves, with no statistically significant difference between waves. On day 5, around half of the patients had elevated transaminases, with no significant difference between waves. Most CT findings were of moderate severity. Clinical severity was higher in the second wave. It was observed that the higher the disease severity, the greater the proportion of patients with elevated hepatic transaminases. The mortality rate was markedly high in cases who had elevated ALT or AST on day 5. The association between elevated enzymes on admission and mortality was seen in the first wave only, with a fatality rate of 22.5% in cases with increased baseline ALT and AST versus 5% in those with normal baseline enzymes. CONCLUSION: There was no significant difference in transaminases between the four waves. Elevated transaminases were positively associated with increased mortality and severity, reflecting their prognostic value.

How frequently MRI modifies thoracolumbar fractures' classification or decision-making? A systematic review and meta-analysis.

PURPOSE: To provide the first meta-analysis of the impact of magnetic resonance imaging (MRI) on thoracolumbar fractures (TLFs) classification and decision-making. METHODS: A systematic review was conducted following PRISMA guidelines. We searched PubMed, Scopus, Cochrane, and Web of Science from inception to June 30, 2023 for studies evaluating the change in TLFs classification and treatment decisions after MRI. The studies extracted key findings, objectives, and patient population. A meta-analysis was performed for the pooled frequency of change in AO fracture classification or treatment decisions from surgical to conservative or vice versa after MRI. RESULTS: This meta-analysis included four studies comprising 554 patients. The pooled frequency of change in TLFs classification was 17% (95% CI 9-31%), and treatment decision was 22% (95% CI 11-40%). An upgrade from type A to type B was reported in 15.7% (95% CI 7.2-30.6%), and downgrading type B to type A in 1.2% (95% CI 0.17-8.3%). A change from conservative to surgery recommendation of 17% (95% CI 5.0-43%) was higher than a change from surgery to conservative 2% (95% CI 1-34%). CONCLUSIONS: MRI can significantly change the thoracolumbar classification and decision-making, primarily due to upgrading type A to type B fractures and changing from conservative to surgery, respectively. These findings suggest that MRI could change decision-making sufficiently to justify its use for TLFs. Type A subtypes, indeterminate PLC status, and spine regions might help to predict a change in TLFs' classification. However, more studies are needed to confirm the association of these variables with changes in treatment decisions to set the indications of MRI in neurologically intact patients with TLFs.

Retinoid Therapy in a Case of Harlequin Ichthyosis with a Short Literature Review.

Harlequin ichthyosis (HI) is a genetically inherited epidermal disorder due to the mutation of the ABCA12 gene, which is responsible for lipid transportation, and presents with large keratinised scales characterised by deep erythematous fissures, with ectropion and eclabium. A moderate number of cases and a high mortality rate have been recorded. In this case report, a pregnant lady gave birth to a 33-week-old premature foetus with characteristic symptoms of HI. After admitting him to the NICU, a multidisciplinary treatment approach was conducted with paediatric dermatologists, ophthalmologists, urologists, and dieticians. The prognosis is positive, with desquamation of the hyperkeratotic plate revealing an erythematous and shiny skin. A short literature review on HI characteristics, diagnostic aids, and management has also been added.
