Abstract
INTRODUCTION AND AIM The optimal composition and duration of antiplatelet therapy after complex percutaneous coronary intervention (PCI) remains unclear. We conducted a meta-analysis to compare 1-3 months of dual antiplatelet therapy (DAPT) followed by monotherapy vs. 12 months of DAPT. METHOD MEDLINE/PubMed, EMBASE, and Cochrane Central Register of Controlled Trials were queried for studies comparing 1-3 months of DAPT followed by monotherapy vs. 12 months of DAPT in the outcomes of complex PCI from inception through January 2023. Outcomes of interest included major bleeding, all-cause mortality, cardiovascular mortality, myocardial infarction (MI), stent thrombosis, target vessel revascularization, and stroke. RESULTS Compared to 12 months, 1-3 months of dual antiplatelet therapy had a weak association with less major bleeding (OR 0.67; 95 % CI, 0.44-1.00; p = 0.05; I2 = 28 %). There were no significant differences between the shorter and longer antiplatelet therapy in terms of all-cause mortality (OR 0.83; 95 % CI, 0.59-1.16; p = 0.21; I2 = 17 %), cardiovascular mortality (OR 0.87; 95 % CI, 0.53-0.42; p = 0.50; I2 = 0), MI (OR 0.97; 95 % CI, 0.69-1.35; p = 0.82; I2 = 32 %), stent thrombosis (OR 1.17, 95 % CI, 0.77-1.76; p = 0.38; I2 = 0 %), target vessel revascularization (OR 1.05, 95 % CI, 0.58-1.89; p = 0.82; I2 = 64 %), or stroke (OR 1.10, 95 % CI, 0.55-2.17; p = 0.37; I2 = 7 %);. CONCLUSION Among patients undergoing complex PCI, DAPT for 1-3 months may be associated with less major bleeding but similar rates of cardiovascular events (death, MI, stroke, stent thrombosis, and revascularization) compared to DAPT for 12 months.

Abstract
INTRODUCTION Cangrelor is a potent intravenous non-thienopyridine P2Y12 inhibitor. We conducted a network meta-analysis to study the efficacy and safety of cangrelor as compared with the oral P2Y12 inhibition, clopidogrel, or placebo in acute coronary syndromes. METHODS This meta-analysis followed the Cochrane collaboration guidelines and the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) protocols. Outcomes of interest included all-cause mortality, myocardial infarction, stent thrombosis, target vessel revascularization, major bleeding, minor bleeding, and the need for blood transfusion. RESULTS The analysis was comprised of 6 studies including 26,444 patients treated with cangrelor, clopidogrel, or placebo. There were no statistically significant differences in the incidence of all-cause mortality, myocardial infarction, stent thrombosis, target vessel revascularization, or major bleeding. Cangrelor was associated with a higher risk of minor bleeding than clopidogrel or placebo, with no difference in requiring blood transfusion. CONCLUSION Cangrelor has comparable outcomes to clopidogrel in patients with acute coronary syndromes and can be used as a reliable alternative in this population.

Abstract
INTRODUCTION Abdominal wall reconstruction (AWR) is an emerging subspecialty within general surgery. The practice of multidisciplinary team (MDT) meetings to aid decision making and improve patient care has been demonstrated, with widespread acceptance. This study presents our initial experience of over 150 cases of complex hernia patients discussed in a newly established MDT setting. METHODS From February 2020 to July 2022 (30-month period), abdominal wall MDTs were held bimonthly. Key stakeholders included upper and lower gastrointestinal surgeons, a gastrointestinal specialist radiologist, a plastic surgeon, a high-risk anaesthetist and two junior doctors integrated into the AWR clinical team. Meetings were held online, where patient history, past medical and surgical history, hernia characteristics and up-to-date computed tomography scans were discussed. RESULTS Some 156 patients were discussed over 18 meetings within the above period. Ninety-five (61%) patients were recommended for surgery, and 61 (39%) patients were recommended for conservative management or referred elsewhere. Seventy-eight (82%) patients were directly waitlisted, whereas seventeen (18%) required preoperative optimisation: three (18%) for smoking cessation, eleven (65%) for weight-loss management and three (18%) for specialist diabetic assessment and management. In total, 92 (59%) patients (including operative and nonoperative management) have been discharged to primary care. DISCUSSION A multidisciplinary forum for complex abdominal wall patients is a safe process that facilitates decision making, promotes education and improves patient care. As the AWR subspecialty evolves, our view is that the "complex hernia MDT" will become commonplace. We present our experience and share advice for others planning to establish an AWR centre.

Abstract
INTRODUCTION The first-generation Watchman 2.5 (W 2.5)TM presented several limitations, such as challenges in implantation within complex left atrial appendage (LAA) anatomies, higher incidence of peri-device leak, device recapture, and device-related thrombus (DRT). The newer generation Watchman FLX (W-FLX)TM was introduced with a modified design aiming to overcome these limitations. The purpose of this meta-analysis is to conduct a comparative assessment of the safety and efficacy of the W-FLX and 2.5 devices in clinical practice. METHOD The meta-analysis was conducted according to the preferred reporting items for systematic review and meta-analysis protocols (PRISMA). Studies were located through a search strategy utilizing PubMed, Cochrane, Google scholar and MEDLINE from inception to March 2023, with a primary objective to compare the safety and efficacy of the W-FLX and W 2.5 devices. After applying the selection criteria, five studies were included in this analysis. RESULTS The analysis included five studies comprising 54,727 patients. The W-FLX is associated with an increase in procedural success (OR 7.49 [95% CI 1.98-28.26, P = 0.02; I2 = 0%]), and a significant reduction in mortality (OR 0.52 [95% CI 0.51-0.54, P<0.01; I2 = 0%], major bleeding 0.57 [95% CI 0.51-0.64, P<0.01; I2 = 0%]), device embolism (OR 0.35 [95% CI 0.18-0.70, P = 0.02; I2 = 0%]), and pericardial effusion (OR 0.33 [95% CI 0.26-0.41, P<0.01; I2 = 0%]). The rates of DRT and stroke were similar between the two groups. CONCLUSION Compared to the W 2.5, the W-FLX was associated with a higher procedural success rate and significantly reduced adverse outcomes including mortality, major bleeding, device embolization, and pericardial effusion.

A Novel Method for Intracavitary Cervical HDR Brachytherapy: Express Finger-Guided Implant Insertion at Simulation Table without Speculum, Cervical Dilatation, Sleeve, Anesthesia, or Sedation. Int J Radiat Oncol Biol Phys 2023; 117:e501-e502.

Abstract
PURPOSE/OBJECTIVE(S) Our purpose is to develop a fast, effective, and independent intracavitary brachytherapy implant insertion method that does not need sleeve insertion, anesthesia or conscious sedation, and that can be performed at the front edge of the simulation table (CT or MRI), using finger guidance without a need for speculum or cervical dilatation. MATERIALS/METHODS From February 2022 to January 2023, we treated 27 locally advanced cervical cancer patients. In the last week of EBRT, we assessed patients with MRI and pelvic exam to determine their eligibility: 89% (24 patients) met the two inclusion criteria for the express insertion which are: the ability to cover any residual disease with intracavitary brachytherapy, and the accessibility of cervix external os. Each patient had 3 HDR express insertions (8Gy x3). A total of 72 consecutive express implant insertions were performed. Each insertion is evaluated for the success of procedure, number of attempts, and time taken. Patients started on laxative 3 days prior to the procedure, and paracetamol & Ibuprofen taken at home 2 hours before the procedure. On arrival, patients used the bathroom, and IM/SC morphine given. Patients were prepared at the front edge of the simulation table and topical lidocaine applied to the cervix. The external os identified with the index finger of one hand which also guided the tandem insertion using the other hand. No cervical dilatation was used. CT simulation was performed to confirm adequate implant placement and to contour and plan CTV-HR and OARs as per GEC-ESTRO/ABS guidelines. RESULTS The success rate was 100% in all the 72 express insertions. >90% (66 insertions) were smooth and fast, i.e., completed in 1 attempt that took <20 minutes. <10% (6 insertions) were challenging but successful, in 2 patients: one patient had an acute anteverted uterus for which suprapubic abdominal pressure facilitated the procedure that took <3 attempts and completed in <40 minutes, the other patient had an acute retroverted uterus which was associated with the most challenging procedure that took >3 attempts and completed in >40 minutes. The success rate was not affected by the type of applicator used. 85% of our applications used multichannel tandem and cylinder, 10% used tandem and ovoids, and 5% used tandem and ring applicators. CONCLUSION Express finger-guided intracavitary brachytherapy implant insertion at the simulation table without speculum, cervical dilatation, sleeve, anesthesia, or sedation is fast, effective, and an independent method that can be used in most cervical cancer patients to complete their planned brachytherapy treatment regardless of limited resources. Practice and dissemination of this innovative method is important especially when operative rooms and anesthesia support are limited (e.g., epidemics and closures) and in centers lacking such support. Further studies are warranted to optimize the procedure and to highlight its significant medical and socioeconomic benefits.

Abstract
Left atrial appendage closure (LAAC) reduces the risk of thromboembolic stroke in atrial fibrillation. Peri-device leak (PDL) after LAAC may affect the subsequent risk of thromboembolism. We conducted a systematic review and meta-analysis to evaluate the effect of PDL after LAAC. We searched PubMed/Medline, Embase, and Google Scholar for studies reporting outcomes of PDL after LAAC from inception through October 2022. The primary outcome was the composite of stroke, transient ischemic attack (TIA), or systemic embolism (SE). Secondary outcomes included all-cause and cardiovascular mortality, ischemic stroke, TIA, and device-related thrombus. Outcomes were pooled using random-effects models. We used I2 statistics to assess statistical heterogeneity; I2 >50% considered significant heterogeneity. This study included 54,279 patients from 11 studies (6 observational, 2 nonrandomized controlled trials [non-RCTs] primary results, 2 RCT post hoc analyses, and 1 analysis combining 2 RCTs data). PDL was associated with a significant increase in the composite outcome of stroke, TIA, or SE (odds ratio 1.63, 95% confidence interval 1.06 to 2.52, p = 0.03, I2 = 43%) as compared with cases with no PDL. There were no significant differences in all-cause or cardiovascular mortality, ischemic stroke, TIA, or device-related thrombus. In conclusion, PDL after LAAC is associated with an increased risk of thromboembolism (composite stroke, TIA, or SE) without impacting mortality.

Abstract
Nirmatrelvir-ritonavir (Paxlovid) is a brand-new oral antiviral medication for treating mild to severe COVID-19. The Food and Drug Administration (FDA) issued an Emergency Use Authorization (EUA) for ritonavir-nirmatrelvir on December 22, 2021, to treat COVID-19. We describe a case of mild COVID-19 infection who developed severe hyponatremia following the administration of Paxlovid. Clinical and laboratory evaluations suggest SIADH, likely secondary to Paxlovid. The potential side effects of this medication still require further study.

Abstract
Pneumoperitoneum is defined as the presence of free air in the abdominal cavity. The most common cause of pneumoperitoneum is intestinal perforation, which usually requires surgical intervention. Nonsurgical pneumoperitoneum (NPS) is defined as the presence of free air in the abdominal cavity without visceral perforation by an intrathoracic route, which commonly occurs in patients on mechanical ventilation in intensive care units. NSP, when properly diagnosed, can be successfully treated conservatively without surgery, and intensivists and surgeons should be aware of this entity associated with mechanical ventilation to avoid unnecessary surgical intervention.

Abstract
BACKGROUND There is limited data on the mortality trends of HCM in the US. OBJECTIVE To study the demographics and trends of mortality in patients with HCM. METHODS A retrospective cohort analysis was done with mortality data of patients with HCM listed as an underlying cause of death in the US Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research database (CDC-WONDER) from January 1999 to December 2020. The analysis took place in February 2022. First, we measured HCM-related Age-Adjusted Mortality Rate (AAMR) per 100,000 US population stratified by sex, race, ethnicity, and geographic area. We then calculated the Annual Percentage Change (APC) for AAMR for each. RESULTS A total of 24,655 HCM-related deaths occurred between 1999 and 2020. The AAMR for HCM-related deaths declined from 0.5/100,000 patients in 1999 to 0.2 in 2020. The APC changes are as follows: -6.8 (95% CI: -11.8 to -1.5) from 2002-2009, -1.23 (95%CI -13.8 to 13.2) from 2009-2014, -6.71 (95%CI -46.2 to 61.7) from 2014-2017 and remained at 2.07 (95%CI -26.1 to 41.1) from 2017-2020. Men had consistently higher AAMR than women. Overall, AAMR in men was 0.4 (95% CI: 0.4-0.5), and in women was 0.3 (95% CI: 0.3-0.3). A similar trend was noticed in men and women over the years, starting from 1999 (AAMR men: 0.7 and women: 0.4) to 2020 (AAMR men: 0.3 and women: 0.2). AAMRs were highest among black or African American patients 0.6 (95% CI: 0.5-0.6), followed by Non-Hispanic and Hispanic white 0.3 (95% CI 0.3-0.3) and Asian or Pacific Islander 0.2 (95% CI 0.2-0.2). There was substantial variation in each region in the US. States such as California, Ohio, Michigan, Oregon, and Wyoming had the highest AAMR. Large metropolitan cities had higher AAMR than non-metropolitan cities. CONCLUSION During the study period from 1999 to 2020, HCM-related mortality steadily decreased. The highest AAMR was observed among men, black patients, and residents of metropolitan areas. States such as California, Ohio, Michigan, Oregon, and Wyoming had the highest AAMR.

Abstract
Heart and blood vessel disorders, such as coronary heart disease, brain vessel disease, rheumatic heart disease, and others, are together referred to as cardiovascular disease (CVD). In this study, we sought to determine how mitochondrial Leucine Transfer RNA genes and CVDs are related (MT-L1 and MT-L2). From CVD patients in Peshawar, a total of 27 saliva samples were taken. Leu-tRNA genes expressed by mitochondria were amplified using polymerase chain reaction after DNA was removed. Ten samples were sent for sequencing after PCR and gene cleaning. We obtained all of the sequenced results, which were subsequently aligned and evaluated against the mitochondrial revised Cambridge Reference Sequence (rCRS). However, in our sequenced samples, Leu-tRNA MT-L1 and MT-L2 genes were determined to be unaltered. Thus, it is suggested that a large population be taken into account while screening for mutations in the mitochondrial encoded Leu-tRNA MT-L1 and MT-L2 genes of cardiac patients in areas of Pakistan. Additionally, it is recommended that patients with cardiac problems should also have other mitochondrial encoded genes checked for potential mutations. This could result in the identification of genetic markers that could be used for early CVD screening in Pakistan.

Background
Atrial fibrillation (AF) and Diabetes mellitus (DM) often coexist. As DM is considered while calculating the thromboembolic risk for AF patients, little is known about the prescription pattern of antithrombotic therapies in patients with AF and DM and their clinical outcomes.
Purpose
In this subsidiary study, we examined the prescription patterns of antithrombotic therapies and clinical outcomes of AF patients with type 2 DM.
Methods
We analyzed data from a single-center cohort of patients with a primary diagnosis of AF in a tertiary cardiac referral hospital in Malaysia from 1st January 2018 to 31st December 2020. Patients' clinical data and information related to antithrombotic therapy were traced through electronic Hospital Information system. A data collection form was used for data collection. The primary endpoint of the study was a composite cardiovascular (CV) event which consists of all-cause mortality, acute coronary syndrome (ACS), ischemic stroke and transient ischemic attack (TIA). The safety endpoint of the study was a bleeding event, defined as hemoglobin drop more than 2 g/dl, blood transfusion and bleeding at critical area.
Results
Of the 1006 AF patients (59.2% male; mean age 64.2 (12.1) years), 400 (39.8%) had a history of DM. Of these, 45.8% (n=183) were using warfarin; 46.5% (n=159) used direct oral anticoagulant (DOAC), 54.0% (n=216) used a single antiplatelet, 11.5% (n=46) used a double antiplatelet, 8.0% (n=32) used triple therapy which consists of two antiplatelet agents with one anticoagulant. The use of single antiplatelet agent (54.0% vs 46.4%, p=0.018) and double antiplatelet agents (11.5% vs 7.1%, p=0.016) was significantly associated with AF with DM patients, whereas there was no association between anticoagulant use and AF patients with or without DM (85.5% vs 82.5%, p=0.209). There was no association in composite CV events between AF patients with or without DM (12.0% vs 10.4%, p=0.427). The proportion of subjects who reported having bleeding events were also did not differ by the presence of AF patients with or without DM. (4.5% vs 2.8%, p=0.151).
Conclusion
Diabetes was associated with increased use of antiplatelet agents; however, DM was not associated with increased risk of composite CV events and bleeding events in patients with concurrent AF. The lack of an association between diabetes and CV risk contrasts with previous research, which could be due to improved diabetes treatment in this cohort of patients with relatively low fasting sugar readings. Further study on the degree of blood glucose as measured by glycosylated hemoglobin (HbA1c) is needed to confirm the finding.

Abstract
BACKGROUND Heart failure with preserved ejection fraction is a complex clinical syndrome marked by different phenotypes and related comorbidities. Transthyretin amyloidosis is an underestimated phenotype. We aim to evaluate the prevalence of transthyretin amyloidosis in heart failure with preserved ejection fraction. METHODS This meta-analysis was conducted according to PRISMA guidelines. A search strategy was designed to utilize PubMed/Medline, EMBASE, and Google scholar to locate studies whose primary objective was to analyze the prevalence of transthyretin amyloidosis in heart failure preserved ejection fraction. RESULTS Of 271 studies initially identified, 5 studies comprising 670 patients were included in the final analysis. The prevalence of transthyretin amyloidosis was 11%. Patients with transthyretin amyloid cardiomyopathy were more likely to be males (RR 1.38; 95% CI 1.09 to 1.75; P<0.01; I2=37%), and more likely to have low voltage criteria on ECG (RR 2.98; 95% CI 1.03 to 8.58; P=0.04; I2=75%) compared with transthyretin negative group. They also have higher SMD of age (SMD 0.73; 95% CI 0.48 to 0.97; P<0.01; I2=0%), and NT-proBNP (SMD 0.48; 95% CI 0.02 to 0.93; P=0.04; I2=36%) compared with transthyretin negative group. On reported echocardiogram, they have higher SMD of mass index (SMD 0.77; 95% CI 0.27 to 1.27; P<0.01; I2=65%), posterior wall thickness (SMD 0.92; 95% CI 0.62 to 1.21; P<0.01; I2=0%), and septal wall thickness (SMD 1.49; 95% CI 0.65 to 2.32; P<0.01; I2=87%) compared with transthyretin negative group. CONCLUSION Transthyretin amyloidosis affects 11% of HFpEF patients. Therefore, screening HFpEF patients at risk of cardiac amyloidosis is warranted.

Abstract
Native pulmonary valve endocarditis is a rare phenomenon as native valve endocarditis tends to typically affect the left sided heart valves. However, the right-sided heart valves can be affected in patients with a history of intravenous drug use, whereby the tricuspid valve is most commonly affected. We present two cases who were diagnosed with native pulmonary valve endocarditis in the absence of congenital heart disease. In the first case, the native pulmonary valve endocarditis was probably a derivative of compounding factors of an enlarged underlying pulmonary artery and staphylococcal bacteraemia. In the second case, a common causal organism of native valve endocarditis following dental treatment and the resultant echocardiography findings was of significant interest. In summary, native pulmonary valve endocarditis is relatively rare complication in the adult population, especially in the absence of congenital heart disease.

Abstract
Epigenetic changes have been linked to a host of disease states. Besides the physiological function of epigenetic changes in regulating cellular function, recent data indicates that key changes in epigenetic activity also play an important pathophysiologic role following neurotrauma specifically. Such manifestations occur through the activation or silencing of different genes. Histone methylation has emerged as a critical component of this process and can be selectively modulated after injury. Pre-clinical studies have resulted in key discoveries regarding specific methylation sites of interest. This focused review highlights some of these early findings and their relationship to clinical outcomes. These findings suggest areas of future investigation and discovery in the quest to develop ideal biomarkers and methods to utilize them in developing therapeutic interventions.

A review of key studies and the risk of device-related thrombosis. AMERICAN JOURNAL OF CARDIOVASCULAR DISEASE 2021; 11:714-722.

Abstract
BACKGROUND Ischemic stroke is a devastating complication of atrial fibrillation (Afib). Anticoagulation is the gold standard to prevent stroke and systemic embolization. However, many patients have a contraindication to oral anticoagulation. The WATCHMAN device, which closes the left atrial appendage, is non-inferior to warfarin to prevent embolic events in clinical trials. Post-procedural anticoagulation is needed to avoid device-related thrombosis. The use of anticoagulants after WATCHMAN implantation in patients with high bleeding risks has been a source of debate. OBJECTIVE This article summarizes the current evidence on anticoagulation following the implantation of the WATCHMAN device, focusing on patients who have an absolute contraindication to oral anticoagulation. OBSERVATION The WATCHMAN device is efficacious and safe in preventing stroke and systemic embolization. Warfarin and aspirin are given for 45 days after implantation. If TEE at 45 days shows minimal residual peri-device flow (≤ 5mm) and no device-related thrombus, warfarin is stopped. This is followed by aspirin and clopidogrel for six months, then aspirin indefinitely. Antithrombotic therapy with aspirin and clopidogrel for six months followed by daily aspirin indefinitely may be feasible for patients with an absolute contraindication to OAC. DOACs are more convenient to use than warfarin, and limited evidence suggests that they are not inferior following implantation of the device. CONCLUSION Following the WATCHMAN implantation, the most often utilized regimen is warfarin followed by antiplatelet treatment. In cases where there is a high risk of bleeding, antiplatelets alone may be sufficient. More research is needed to tailor the existing antithrombotic regimen to the needs of patients.

Abstract
AIM To assess the value of the ratio of signal intensities at high and low b-values (b800/b0 ratio) during diffusion-weighted imaging (DWI) for gallbladder cancer diagnosis. MATERIALS AND METHODS All patients presenting with suspicious gallbladder lesions between January 2011 and December 2016 who underwent DWI and histopathological diagnoses of the lesions were assessed. RESULTS Thirty-two patients (24 men, eight women) were identified. Eighteen patients had benign gallbladder lesions while 14 had malignant lesions. The mean apparent diffusion coefficient (ADC) value was 1.62 (±0.57)×10-3 mm2/s for benign cases and 1.27 (±0.39)×10-3 mm2/s for malignant cases; this difference was not significant (p=0.0773). The mean b800/b0 ratio was 0.31 (±0.19) for benign cases and 0.48 (±0.13) for malignant cases; this difference was significant (p=0.007). The ROC curve for b800/b0 had an AUC of 0.782 (95% confidence interval [CI]: 0.616-0.947) with a sensitivity and specificity of 85.7% and 72.2%, respectively, at a cut-off point of 0.33. CONCLUSION The b800/b0 ratio can help differentiate benign and malignant gallbladder lesions and may be more reliable than ADC values in quantitative DWI assessments.
