Abstract
INTRODUCTION The Fontan procedure is the palliative procedure of choice for patients with single ventricle physiology. Pulmonary vascular disease (PVD) is an important contributor to Fontan circulatory failure. AREAS COVERED We review the pathophysiology of PVD in patients with Fontan palliation and share our initial experience with optical coherence tomography (OCT) in supplementing standard hemodynamics in characterizing Fontan-associated PVD. In the absence of a sub-pulmonary ventricle, low pulmonary vascular resistance (PVR; ≤2 WU/m2) is required to sustain optimal pulmonary blood flow. PVD is associated with adverse pulmonary artery (PA) remodeling resulting from the non-pulsatile low-shear low-flow circulation. Predisposing factors to PVD include impaired PA growth, endothelial dysfunction, hypercoagulable state, and increased ventricular end-diastolic pressure. OCT parameters that show promise in characterizing Fontan-associated PVD include the PA intima-to-media ratio and wall area ratio (i.e. difference between the whole-vessel area and the luminal area divided by the whole-vessel area). EXPERT OPINION OCT carries potential in characterizing PVD in patients with Fontan palliation. PA remodeling is marked by intimal hyperplasia, with medial regression. Further studies are required to determine the role of OCT in informing management decisions and assessing therapeutic responses.

Abstract
OBJECTIVES The SavvyWire(OpSens Medical) is a support wire for transcatheter aortic valve replacement (TAVR) procedures that, in addition to its dedicated left ventricle (LV) pacing capabilities, has a distal pressure sensor that measures live transvalvular hemodynamics during the procedure. We aimed to determine the safety, efficacy, and functionality of the SavvyWire during TAVR procedures in an all-comer population. METHODS We performed a multicentric, prospective, observational, single-arm, all-comers registry of patients with symptomatic, severe aortic stenosis undergoing TAVR in 3 Canadian centers. Data were collected in a dedicated database, and pre-specified questionnaires were fulfilled by the heart team implanters after each procedure. RESULTS A total of 60 patients were included (mean age: 78.6 ± 7.2 years; 51% women; mean Society of Thoracic Surgeons score: 2.2 ± 1.6%). TAVR was performed through a transfemoral approach in 90% of cases, and balloon- and self-expandable valves were used in 73% and 27% of patients, respectively. There were no cases of LV perforation, guidewire deformation, significant loss of capture, or major software malfunction. The rate of successful delivery of the TAVR system was 100%, and effective LV pacing was achieved in 98% of patients. The pre-TAVR mean gradient was 39 ± 14 mm Hg while the final post-TAVR gradient was 8 ± 5 mm Hg; the mean aortic systolic pressure during rapid pacing was 54 ± 12 mm Hg. In 97% of the TAVR procedures, SavvyWire's functionality was reported to be better or similar to other TAVR workhorse support wires. CONCLUSIONS SavvyWire was safe, effective, and functional for live transvalvular hemodynamic evaluation and rapid pacing during TAVR procedures. More studies with larger sample sizes and comparison against different wires and gradient measurement methods are warranted.

Abstract
The presence of a systemic right ventricle (sRV) with biventricular physiology (biV) is associated with increased patient morbidity and mortality. To date, no pharmacologic therapy for heart failure has been proven effective for patients with systolic dysfunction of the sRV-biV. We designed a randomized, double-blind, placebo-controlled crossover trial to compare sacubitril/valsartan treatment to placebo in adults (aged ≥ 18 years) with moderate-to-severe sRV-biV dysfunction and New York Heart Association functional class II to III symptoms. Two primary efficacy endpoints are assessed in the trial: exercise capacity (submaximal exercise duration) and neurohormonal activation (N-terminal prohormone brain natriuretic peptide). Secondary objectives include assessing a change in the Kansas City Cardiomyopathy Questionnaire score and evaluating the safety and tolerance of sacubitril/valsartan. A 6-week open run-in phase identifies the maximum tolerated dose of sacubitril/valsartan, up to 97 mg/103 mg twice daily. After a 2-week washout period, patients are randomized 1:1 to sacubitril/valsartan treatment vs placebo for a 24-week phase, followed by another 2-week washout period and subsequent crossover to the alternative treatment arm for an additional 24-week phase. Data to assess primary and secondary endpoints are collected at baseline and at the end of each phase. A total of 48 patients is required to provide > 80% power to detect a 30% difference in distance walked and in N-terminal prohormone brain natriuretic peptide levels with sacubitril/valsartan treatment vs placebo, each with a 2-sided P-value of 0.025. In summary, the Prospective Comparison of Angiotensin Receptor-Neprilysin Inhibitor vs Placebo in Patients With Congenital Systemic Right Ventricular Heart Failure Trial (PARACYS-RV) should determine the role of sacubitril/valsartan in treating heart failure in patients with sRV-biV and carries the potential to alter management of this patient population.

Abstract
INTRODUCTION Subtotal cholecystectomy (STC) is a safe approach in difficult cholecystectomies to prevent bile duct and vascular injury. However, the gallbladder remnant can become symptomatic, necessitating further surgical intervention. This study evaluates the safety profile and perioperative outcomes of remnant cholecystectomy (RC) performed under intraoperative ultrasound guidance. METHODS We retrospectively reviewed the records of all patients that underwent RC under intraoperative ultrasound guidance in 2009 and 2019. Pre-, intra- and postoperative details of patients who underwent RC were obtained from patients' electronic and paper copy records. RESULTS Ninety-seven patients underwent STC during the study period. Of this cohort, 16 patients (16.5%) presented with symptomatic gallbladder remnant over a median follow-up period of 14 months (interquartile range [IQR] 2-26). The median age was 64 years (IQR 54-69) with an equal male-to-female distribution. The median body mass index was 31kg/m2 (IQR 28-33). Twelve of 16 patients (75%) then proceeded to elective RC. Intraoperative ultrasound was used in all cases to identify the location of the remnant gallbladder and biliary anatomy. The median operative time was 88min (IQR 80-96), with 67% completed laparoscopically. No patients suffered bile duct injury. The median hospital stay was 3 days (IQR 1-5). During the follow-up period, eight patients (67%) reported symptom resolution. CONCLUSIONS RC is a safe operation that can be performed laparoscopically even after previous open subtotal cholecystectomy. We recommend the routine use of intraoperative ultrasound as an adjunct for identifying remnant gallbladder and biliary anatomy in all patients.

Abstract
BACKGROUND Data regarding the safety and long-term effectiveness of percutaneous closure of paravalvular leak (PVL) after transcatheter aortic valve implantation (TAVI) are scarce. AIMS This study aims to present a large multicentre international experience of percutaneous post-TAVI PVL closure. METHODS All patients who underwent percutaneous post-TAVI PVL closure in 14 hospitals across Europe and North America between January 2018 and October 2022 were included. RESULTS Overall, 45 patients (64% male) were enrolled. The median age was 80 years (75-84). Among them, 67% and 33% had self-expanding and balloon-expandable valve implantations, respectively. Baseline post-TAVI PVL was severe in 67% of cases and moderate in the rest. The time from index TAVI to PVL closure procedure was 16.1 (8.7-34.8) months. Most patients were in NYHA Class III and IV (73%) before the procedure, and 40% had referred hospitalisations for heart failure between TAVI and the PVL closure procedure. Successful PVL closure was achieved in 94%, reducing regurgitation to ≤mild in 91% and moderate in the rest. The Amplatzer Valvular Plug III was the most frequently used device (27 cases), followed by the Amplatzer Valvular Plug 4. The incidence of severe adverse events was 11%. None of the patients died during the index hospitalisation. During long-term follow-up (21.7±16.2 months), the all-cause mortality rate was 14%, and patients presented improvement in functional status and a significant reduction in the rate of hospitalisation for heart failure (from 40% to 6%). CONCLUSIONS Percutaneous PVL closure is a feasible and safe option for treating post-TAVI leaks. Successful PVL reduction to mild or less could be associated with acute and long-lasting improvements in clinical outcomes.

Abstract
INTRODUCTION Subtotal cholecystectomy (STC) is an alternative to total cholecystectomy (TC) in patients with severe inflammation/adhesions around the hepatocystic triangle. This study aimed to evaluate the safety profile of STC. METHODS We retrospectively reviewed all patients who had STC at our unit between February 2009 and August 2019. STC was divided into two types, reconstituting (R-STC) and fenestrating (F-STC), depending on whether the gall bladder remnant was closed or left open. Patients who had cholecystectomy for gall bladder malignancy or as part of another operation were excluded from the study. RESULTS A total of 5,664 patients underwent cholecystectomy during the study period. Of these, 97 (1.7%) underwent STC. The laparoscopic to open conversion rate was high at 48.8% (47 cases), as was the overall postoperative complication rate (45.4%, 44 cases). No patient suffered iatrogenic bile duct injury. Nineteen patients (19.6%) suffered postoperative bile leak. This was significantly higher in patients who had STC in the acute setting (41% vs 13% for elective STC cases; p=0.04). There was no significant difference in rate of bile leak or other complications between R-STC and F-STC types. The 90-day readmission rate was 8.2% (8 cases). No mortalities were recorded within 90 days post STC. CONCLUSIONS STC seems to be an effective technique to avoid bile duct injury in difficult cholecystectomy cases. However, the perioperative morbidity associated with STC is relatively high. Surgeons should be aware of the risks of STC and take appropriate steps to minimise them.

Abstract
BACKGROUND Left atrial appendage occlusion (LAAO) has emerged over the last two decades as an efficient and safe alternative to oral anticoagulation for stroke prevention. However, LAAO remains challenging due to the variety of anatomies and the multiple steps required to complete the procedure. AIMS We report the first series of in-human experience of the new all-in-one VersaCross Connect system designed to access the left atrium in conjunction with the delivery sheath for deployment of the WATCHMAN FLX device. METHODS We prospectively included the first nine consecutive cases of LAAO using the new VersaCross Connect system for WATCHMAN FLX device implantation at the Montreal Heart Institute and Vancouver General Hospital and collected procedural duration (defined as time from femoral access to closure) and time from transseptal puncture to device delivery. RESULTS VersaCross Connect system use for WATCHMAN FLX implantation was successful in all patients. No procedural complication was reported. Mean procedural time was 31 ± 6.3 min with a fluoroscopy time of 6.7 ± 4.9 min. The mean delay between the transseptal puncture and device implantation was 12.2 ± 1.9 min. CONCLUSIONS We showed that the VersaCross Connect system was safe and successfully used in all first nine cases. This new system helped improve the efficiency of the procedure.

Abstract
We developed humanized biosimulator to predict the risk of coronary obstruction among high-risk patients undergoing valve-in-valve (ViV) procedures. In this case, based on unchanged instantaneous wave-free ratio values measured during a ViV simulation session, the procedure was performed safely in the patient the day afterward, without coronary artery issues and with good hemodynamic results. (Level of Difficulty: Advanced.).

Abstract
Abstract
Background/Purpose
Application-based technology has been studied for patient engagement and collecting patient-reported outcomes (PROs) in several one-day surgical specialties with limited research in transcathether valve therapies program. The aim of study was to determine the effectiveness of app-based technology for collecting PROs, improving the patient experience, and reducing health services utilization in a transcatheter valve implantation (TAVI) program.
Methods
Patients accessed an interactive app via smartphones. Patients were guided from their visit to the TAVI clinic via reminders, tasks, PRO surveys, and evidence-based education. They received notifications and health surveys 2 days before the procedure to ensure they were ready for the procedure. In the postoperative period, patients were engaged with daily health surveys to track warning signs and recovery milestones for 7 days. Based on the patient's signs and symptoms, the app escalated lower risk issues to self-care education or higher risk issues to the care team (TAVI program's nurse coordinator). Follow-up surveys and Kansas City Cardiomyopathy Questionnaire (KCCQ12) were sent to patients at 1, 3, 6 and 12 months to evaluate their functional recovery. All data are reported with median and interquartile range.
Results
227 patients underwent a TAVI procedure at the MHI from December 2020 to October 2021. 99 patients (44%) accepted to use the application and formed the digital application group. The two groups (digital application group vs. non-digital application group) were comparable in terms of age (76 years old (72, 81) vs 77 years old (71,82)), STS (Society of Thoracic Surgeons' risk model) score (6,1% vs 6,7%), vascular complications (8,1 vs 7.8%) and post procedure pacemakers (10,1% vs 10.9%). In the digital application group, 93% recommended the application, 95% said it helped them feel more confident before the procedure and 84%, after the procedure. KCCQ12 score (PRO) improved from 34/70 (28, 41) at baseline to 54/70 (48,62) at 1 month after the procedure and remained stable over the 12 months. Digital application use helped to reduce emergency visits by 33.5% (7.9 vs 11.9%) and rehospitalizations related to the procedure by 50.1% (7.9% vs 15.9%) in the month following the TAVI procedure.
Conclusion
App-based technology for patient engagement is an effective modality to enhance the patient experience, better understand the trajectory of recovery, gather PRO and reduce unnecessary health services utilization in aging population of a TAVI program.

Abstract
Abstract
Background
Chemotherapy induced cognitive impairment (CICI) is a term used for the cognitive dysfunction reported with non-central nervous system cancer patients during or after chemotherapy. Recent neuroimaging studies have shown decreased activation in cancer patients during cognitive tasks post-chemotherapy. Structural changes are sought to be associated with cognitive decline in cancer survivors after chemotherapy. Here we aim to investigate the neuroimaging findings of structural abnormalities and gray matter alterations associated with chemotherapy in cancer survivors.
Material and Methods
A systematic search through PubMed database for peer-reviewed English-language studies yielded a total of 302 studies. Eligible studies were included in the activation likelihood estimation (ALE) meta-analysis if they reported coordinates in a stereotactic format (MNI or Talairach space) for voxel-based morphometric (VBM) studies on gray matter volume and post-chemotherapy cancer survivors compared to matched healthy controls. GingerALE (3.0.2) software from Brainmap.org was used to perform the ALE meta-analysis with threshold settings of uncorrected P-value < 0.001 for multiple comparisons.
Results
The study sample included 299 patients comprised of breast cancer survivors (BCS), childhood acute lymphocytic leukemia (ALL) survivors, ovarian cancer survivors (OCS) and lung cancer with 279 matched healthy controls from 12 studies and 21 experiments. ALE-maps for post-chemotherapy cancer survivors showed reduced gray matter volume in comparison to healthy controls in the left inferior frontal gyrus, right thalamus, right superior frontal gyrus, right medial frontal gyrus and right cerebellum (peak coordinates: [-43,40,-6], [23,-29,2], [14,30,55], [9,57,-16], [9,-78,-41] respectively, and cluster size of 544 mm3, 312 mm3 and 257 mm3, 296 mm3, 297 mm3 respectively).
Conclusion
This is the first ALE meta-analysis that studied the converged areas of reduced gray matter volume in post-chemotherapy cancer survivors. Our findings of reduced gray matter volume in frontal regions and cerebellum might be responsible for the cognitive dysfunction in executive function, attention, and memory observed in cancer survivors. Further studies are needed to assess the impact of different chemotherapeutic regimens related to CICI .

Abstract
Interventions in adults with congenital heart disease (ACHD) focus on surgical and percutaneous interventions in light of rapidly evolving ACHD clinical practice. To bring rigour to our process and amplify the cumulative nature of evidence ACHD care we used the ADAPTE process; we systematically adjudicated, updated, and adapted existing guidelines by Canadian, American, and European cardiac societies from 2010 to 2020. We applied this to interventions related to right and left ventricular outflow obstruction, tetralogy of Fallot, coarctation, aortopathy associated with bicuspid aortic valve, atrioventricular canal defects, Ebstein anomaly, complete and congenitally corrected transposition, and patients with the Fontan operation. In addition to tables indexed to evidence, clinical flow diagrams are included for each lesion to facilitate a practical approach to clinical decision-making. Excluded are recommendations for pacemakers, defibrillators, and arrhythmia-directed interventions covered in separate designated documents. Similarly, where overlap occurs with other guidelines for valvular interventions, reference is made to parallel publications. There is a paucity of high-level quality of evidence in the form of randomized clinical trials to support guidelines in ACHD. We accounted for this in the wording of the strength of recommendations put forth by our national and international experts. As data grow on long-term follow-up, we expect that the evidence driving clinical practice will become increasingly granular. These recommendations are meant to be used to guide dialogue between clinicians, interventional cardiologists, surgeons, and patients making complex decisions relative to ACHD interventions.

Abstract
A cowpea thresher that uses petrol engine was developed to overcome drudgery of threshing with manually operated thresher and also to replace motorized cowpea thresher that cannot be used in areas where there is no supply of electricity. The performance tests on the machine were replicated three times using 10000, 8000 and 6000 grams of kannanado cowpea pods at the threshing cylinder speed of 700, 800 and 900 rpm each and moisture contents of 11.05%, 13.65% and 14.75% respectively based on the following parameters; Threshing efficiency, throughput capacity and percentage seed damage. The findings of the tests showed that the thresher had highest threshing efficiency of 98% at moisture content of 11.05%, threshing cylinder speed of 900 rpm and feed rate of 6 kg/hr. The maximum throughput capacity was observed to be 46.18 kg/hr at the feed rate of 10 kg/hr, 11.05% grain moisture content and threshing cylinder speed of 900 rpm. A highest cleaning efficiency and grain damage of 93.06% and 4.90% respectively were observed. This revealed that as the cylinder speed increased the threshing and cleaning efficiency and the throughput capacity also increased whereas feed rate and moisture content were decreased. The test also showed that high moisture content has a tendency to reduce the mechanical seed damage for the variety (kannanado) of cowpea investigated. Therefore, cowpea moisture contents of 11.05 % and threshing cylinder speeds of 900 rpm are the crop-machine parameters combination for optimum thresher performance. The performance of the machine is satisfactory; small-scale farmers will find more comfort in using it for threshing.

Abstract
Bicuspid aortic valve (BAV) is the most frequent congenital anomaly and has a natural evolution toward aortic regurgitation or stenosis due to the asymmetrical valve function associated with an evolutive ascending aortopathy. Several BAV classifications exist describing the presence and number of raphe, amount and location of calcium, and the symmetry of the functional cusps. The impact of BAV morphology on transcatheter aortic valve implantation (TAVI) outcomes still remains little investigated. Pivotal randomized trials comparing TAVI with surgery have excluded BAV until yet. However, data from registries and observational studies including highly selected patients have shown promising results of TAVI in BAV. With this review, we aimed at describing anatomical and pathophysiological characteristics of BAV, discussing the main aspects to assess diagnostic imaging modalities, and giving an overview of TAVI outcomes and technical considerations specific to BAV morphology.

Abstract
Transfemoral access remains the most widely used peripheral vascular approach for transcatheter aortic valve implantation (TAVI). Despite technical improvement and reduction in delivery sheath diameters of all TAVI platforms, 10-20% of patients remain not eligible to transfemoral TAVI due to peripheral artery disease. In this review, we aim at presenting an update of recent data concerning transfemoral access and percutaneous closure devices. Moreover, we will review peripheral non-transfemoral alternative as well as caval-aortic accesses and discuss the important features to assess with pre-procedural imaging modalities before TAVI.

Abstract
A novel nanomaterial, bacterial cellulose (BC), has become noteworthy recently due to its better physicochemical properties and biodegradability, which are desirable for various applications. Since cost is a significant limitation in the production of cellulose, current efforts are focused on the use of industrial waste as a cost-effective substrate for the synthesis of BC or microbial cellulose. The utilization of industrial wastes and byproduct streams as fermentation media could improve the cost-competitiveness of BC production. This paper examines the feasibility of using typical wastes generated by industry sectors as sources of nutrients (carbon and nitrogen) for the commercial-scale production of BC. Numerous preliminary findings in the literature data have revealed the potential to yield a high concentration of BC from various industrial wastes. These findings indicated the need to optimize culture conditions, aiming for improved large-scale production of BC from waste streams.

Abstract
INTRODUCTION Antibiotic resistance is a burgeoning problem worldwide. The trend of bacterial resistance has increased over the past decade in which more common bacteria are becoming resistant to almost all the antibiotics currently in use, posing a threat to humans and even livestock. METHODS The databases used to search for the relevant articles for this review include PubMed, Science Direct, and Scopus. The following keywords were used in the search: Antimicrobial resistance, Malaysian action plan, antibioticresistant bacteria, and Malaysian National Surveillance on Antimicrobial Resistance (NSAR). The relevant articles published in English were considered. RESULTS The antibiotic-resistant bacteria highlighted in this review showed an increase in resistance patterns to the majority of the antibiotics tested. The Malaysian government has come up with an action plan to create public awareness and to educate them regarding the health implications of antibiotic resistance. CONCLUSION Antimicrobial resistance in Malaysia continues to escalate and is attributed to the overuse and misuse of antibiotics in various fields. As this crisis impacts the health of both humans and animals, therefore a joined continuous effort from all sectors is warranted to reduce the spread and minimize its development.

Abstract
Abstract
Introduction
Recent research on the management of cholecystolithiasis with co-existing choledocholithiasis suggests performing cholecystectomy within 24 hours after ERCP has favourable outcomes. However, this target can be difficult to achieve in the NHS due to limited resources.
Method
This retrospective study includes 444 patients who underwent successful ERCP before cholecystectomy. We examined the impact of the duration of ERCP to cholecystectomy and post ERCP complications on operative difficulty and patient outcomes. We also report on gallstone related readmissions and rate of retained stones.
Results
The median duration from ERCP to cholecystectomy was 75 days, with a 14% readmission rate between their first successful ERCP and cholecystectomy.
Our analysis showed a statistically significant negative correlation between ERCP-to-cholecystectomy duration and postoperative stay. Readmissions increased with time, but this did not reach statistical significance. The occurrence of post ERCP complications significantly increased postoperative stay and the open conversion rate.
Conclusions
In contrast to recent research, our analysis suggests that early cholecystectomy post ERCP is not associated with better outcome. However, the impact of gallstone related readmissions needs further analysis. Post ERCP complication could serve as a predictor for operative difficulty and longer postoperative stay. It should be considered when planning the cholecystectomy.

Abstract
Background: Traditionally, stroke rehabilitation outcomes are based on indicators of physical function, such measures may underrate the all-inclusive impact of stroke such as oral health.Objectives: To investigate the relationship between upper extremity motor function and oral hygiene status as well as the impact of stroke on Oral Health-Related Quality of Life (OHRQoL).Methods: Sixty stroke survivors were included in this cross-sectional survey. Spasticity and motor function/mobility of the affected upper extremity were assessed using the Modified Ashworth Scale and Action Research Arm Test, respectively. Oral hygiene was assessed using the Simplified Oral Hygiene Index and oral health impact was assessed using the 14-item Oral Health Impact Profile. Pearson's moment correlation coefficient was used to determine the relationship between oral hygiene and upper extremity motor function variables.Results: There were significant relationships between the oral hygiene index and Shoulder muscles spasticity (r = 0.374, p = .01), wrist muscles spasticity (r = 0.352, p = .01), as well as basic mobility (r = 0.423, p = .01). An estimated 8% (n = 5) of study participants have their QoL strongly impacted by their oral health.Conclusions: Upper extremity motor function variables such as spasticity and basic mobility matters in determining oral hygiene status after stroke. Stroke has little impact on oral health-related quality of life.

Abstract
INTRODUCTION The susceptibility patterns of anaerobes are becoming less predictable due to the emergence of anaerobic resistance trends to antibiotics; hence increasing the importance of the isolation and antimicrobial susceptibility testing of anaerobes. MATERIALS AND METHODS This study investigated the isolation of anaerobes from the clinical specimens of Hospital Sungai Buloh, Malaysia, from January 2015 to December 2015. All isolates were identified using the API 20A system (bioMérieux, France). Antimicrobial susceptibility testing was performed using the E-test (bioMérieux, France). RESULTS The proportion of obligate anaerobes isolated from the clinical specimens was 0.83%. The Gram-positive anaerobes were most susceptible to vancomycin and imipenem, showing 100% sensitivity to these antimicrobials, followed by clindamycin (86.3%), penicillin (76.7%), and metronidazole (48.9%). Meanwhile, Gram-negative anaerobes were most susceptible to metronidazole (96%) followed by imipenem (89%), clindamycin (79%), and ampicillin (32%). The present study also showed that 3 out of 12 Bacteroides fragilis isolates were resistant to imipenem. CONCLUSION This study demonstrated the differences in the susceptibility patterns of anaerobes towards commonly used antimicrobials for the treatment of anaerobic infections. In summary, continuous monitoring of antimicrobial resistance trends among anaerobes is needed to ensure the appropriateness of treatment.

Abstract
Background:Osteoarthritis (OA) and rheumatoid arthritis (RA) are the most frequent inflammatory diseases of the musculoskeletal system, which could not be differentiated in their early stages, and characterized by degradation of articular cartilage and impairment of joint function. Sometimes, criteria and radiography are not insufficient to distinguish early-stages of RA and OA and predict disease course, and therefor biomarkers that help clinicians to early diagnose disease are essential.Objectives:The aim of this study is to estimate serum level of Matrix metalloproteinase 3 (MMP3) and hrdroxyproline (HP) in early RA and OA patients to see if they can be used to differentiate both diseases at their early stagesMethods:The aim of this study is to estimate serum level of Matrix metalloproteinase 3 (MMP3) and hrdroxyproline (HP) in early RA and OA patients to see if they can be used to differentiate both diseases at their early stagesResults:We found a highly significant elevation of serum MMP3 in OA patients group compared to RA patients and control groups. We also found a highly significant elevation of MMP3 in RA patients than control group,(P < 0.001). Meanwhile, we found a highly significant elevation of HP in OA patients than in RA patients and control groups, (P < 0.001), whereas there was no significant difference between HP in RA patients and control groups (P > 0.05).Table 1.Demonstration of serum levels of MMP3 and HP in all groups.“Enzyme”OA(n=40)RA(n=40)Control(n=40)p-valueMMP3 pg/mL559.92±1112.84153.25±162.0559.79±63.54<0.001HPµg/mL12.87±18.754.81±6.894.52±1.55<0.001HPµg/mL4.81±6.894.52±1.55> 0.05Conclusion:Our results suggest that serum levels of Hydroxyproline (HP) rather than MMP3 could be used as a potential biomarker for early differentiation between osteoarthritis (OA) and rheumatoid arthritis (RA) when diagnostic criteria failed to be fulfilled.References:[1]Benedetti S, Canino C, Tonti G, Medda V, Calcaterra P, Nappi G, Salaffi F, Canestrari F.

Abstract
Abstract
Introduction
Right ventricular (RV) size informs about prognosis and need for pulmonary valve replacement in patients with repaired tetralogy of Fallot (rTOF). Cardiac magnetic resonance (CMR) is considered the reference standard for measurement of RV volumes. Despite known limitations for RV evaluation, 2D transthoracic echocardiography (TTE) remains the primary and most available imaging modality in the rTOF population.
Purpose
To determine which TTE RV size parameters best correlate with CMR-derived indexed RV end-diastolic (RVEDVi) and end-systolic (RVESVi) volumes in the rTOF population. We sought to determine the best TTE measurement thresholds to predict normal RV volume (RVEDVi ≤110 mL/m2) and significant RV dilatation by CMR (RVEDVi ≥150ml/m2).
Method
We retrospectively enrolled all rTOF patients followed at a single-center between 2010 and 2018 who had both TTE and CMR exams performed within a 12-month interval. All TTE exams were reviewed by an observer measuring RV areas, RV inlet and RV outlet at end-diastole and end-systole. Analyses of CMR studies were performed by 3 observers who measured RV area, RV inlet, RV outlet and RV volumes at end-diastole and end-systole. Correlations between TTE and CMR parameters were performed using Pearson correlation coefficients. Using the TTE RV parameters with the strongest correlation with CMR, we subsequently determined thresholds to predict a CMR RVEDVi ≤110ml/m2 and ≥150ml/m2 using ROC analysis.
Results
We enrolled 130 patients (59 women [45%], mean age 43±12.8 years). Median age at TOF repair was 4 [3–6] years; 18 patients (14%) had subsequent pulmonary valve replacement. Median interval between TTE and CMR exams was 114 [59–239] days. There were significant correlations between all TTE parameters and CMR RVEDVi. TTE indexed RV end-diastolic area (RVEDAi) most strongly correlated with CMR RVEDVi (r=0.73, p<0.0001). All TTE RV parameters significantly correlated with CMR RVESVi but indexed RV end-systolic area had the strongest correlation (r=0.77, p<0.0001). ROC analysis performed to predict RVEDVi of ≤110ml/m2 and ≥150ml/m2 using TTE RVEDAi revealed areas under the curve of 0.86±0.04 and 0.90±0.03, respectively. A TTE RVEDAi ≤17cm2/m2 predicted a normal CMR RV volume (≤110ml/m2) with a sensitivity of 90% and a specificity of 74%. A TTE RVEDAi ≥19cm2/m2 predicted a CMR RVEDVi ≥150 mL/m2 with a sensitivity of 93% and a specificity of 76%.
Conclusion
In rTOF patients, both diastolic and systolic TTE RV area best correlate with CMR-derived RV end-diastolic and end-systolic volumes. A cut-off value of TTE RVEDAi of 19cm2/m2 is 93% sensitive and 76% specific to predict a CMR RVEDVi ≥150ml/m2. Simple RV size measurement using TTE may help inform the need and frequency of CMR evaluations in rTOF patients.

Abstract
BACKGROUND Echocardiographic evaluation of the systemic right ventricle (sRV) remains challenging in patients with transposition of the great arteries (TGA) corrected by an atrial switch (AS) and with congenitally corrected TGA (ccTGA). The aim of this study was to determine the interobserver and intraobserver variability of echocardiographic parameters for sRV size and systolic function. METHODS Six independent observers retrospectively interpreted 44 previously acquired echocardiograms (25 patients with TGA/AS and 19 patients with ccTGA). Quantitative parameters included inlet and longitudinal diameters, systolic and diastolic areas, fractional area change (FAC), and wall thickness. sRV dilatation and systolic function were qualitatively graded as normal, mild, moderate, or severe. sRV hypertrophy was graded as present or absent. Intraclass correlation coefficients (ICCs) and Kappa statistics were computed to assess interobserver variability. Images from 10 patients (5 TGA/AS and 5 ccTGA) were reinterpreted at a 1-month interval, and ICC and Kendall tau b statistics were computed to assess intraobserver variability. RESULTS Interobserver and intraobserver agreement were good to excellent for sRV diameters, areas and FAC (ICC, 0.49-0.97), except for the sRV wall thickness (ICC < 0) and the FAC for 1 observer. Interobserver agreement was poor for the qualitative assessment of sRV size and systolic function (Kappa < 0.25), but with a good to excellent intraobserver agreement. CONCLUSIONS These findings suggest that overall appreciation of sRV size and systolic function relies on variable interpretation of measurements by observers. Readers experienced in CHD and with clear thresholds for quantitative parameters, along with a validated algorithm, are required to guide the evaluation of sRV.

Abstract
Background There is a paucity of data regarding late‐onset pulmonary hypertension (PH) in patients with transposition of the great arteries and atrial switch surgery. Methods and Results A retrospective cohort study was conducted on 140 adults with transposition of the great arteries and atrial switch surgery, age 37.3±7.8, 37.1% female, in order to assess the prevalence and characteristics of late‐onset PH and explore associated factors. Patients were followed for a median of 32.3 years after atrial switch surgery and 10.0 years after their first referral visit. PH was detected in 18 of 33 (54.5%) patients who had invasive hemodynamic studies. Average age at diagnosis of PH was 33.9±8.1 years. PH was postcapillary in all, with a mean pulmonary artery pressure of 36±12 mm Hg and mean pulmonary capillary wedge pressure of 28±8 mm Hg. PH was diagnosed in 13 of 17 (76.5%) patients who had cardiac catheterization for heart failure or decreased exercise tolerance. In multivariable analyses, systemic hypertension (odds ratio 9.4, 95% confidence interval 2.2‐39.4, P=0.002) and heart failure or New York Heart Association class III or IV symptoms (odds ratio 49.8, 95% confidence interval 8.6‐289.0, P<0.001) were independently associated with PH. Patients with PH were more likely to develop cardiovascular comorbidities including atrial (P=0.001) and ventricular (P=0.008) arrhythmias, require hospitalizations for heart failure (P<0.001), and undergo tricuspid valve surgery (P<0.001). Mortality was significantly higher in patients with PH (hazard ratio 9.4, 95% confidence interval 2.1‐43.0], P<0.001). Conclusions Late‐onset postcapillary PH is highly prevalent in adults with transposition of the great arteries and atrial switch surgery and is associated with an adverse prognosis.

Abstract
Background High-density lipoproteins (HDL) favorably affect endothelial progenitor cells (EPC). Circulating progenitor cell level and function are impaired in patients with acute coronary syndrome (ACS). This study investigates the short-term effects of reconstituted HDL (rHDL) on circulating progenitor cells in patients with ACS. Methods and Findings The study population consisted of 33 patients with recent ACS: 20 patients from the ERASE trial (randomized to receive 4 weekly intravenous infusions of CSL-111 40 mg/kg or placebo) and 13 additional patients recruited as controls using the same enrolment criteria. Blood was collected from 16 rHDL (CSL-111)-treated patients and 17 controls at baseline and at 6–7 weeks (i.e. 2–3 weeks after the fourth infusion of CSL-111 in ERASE). CD34+ and CD34+/kinase insert domain receptor (KDR+) progenitor cell counts were analyzed by flow cytometry. We found preserved CD34+ cell counts in CSL-111-treated subjects at follow-up (change of 1.6%), while the number of CD34+ cells was reduced (-32.9%) in controls (p = 0.017 between groups). The level of circulating SDF-1 (stromal cell-derived factor-1), a chemokine involved in progenitor cell recruitment, increased significantly (change of 21.5%) in controls, while it remained unchanged in CSL-111-treated patients (p = 0.031 between groups). In vitro exposure to CSL-111 of early EPC isolated from healthy volunteers significantly increased CD34+ cells, reduced early EPC apoptosis and enhanced their migration capacity towards SDF-1. Conclusions The relative increase in circulating CD34+ cells and the low SDF-1 levels observed following rHDL infusions in ACS patients point towards a role of rHDL in cardiovascular repair mechanisms.

Abstract
In the current study, tyrosine aminotransferase (TAT) as a target enzyme was purified from the liver of control and Schistosoma-infected mice that was subjected to catalytic investigation. The purified enzyme has a single band on SDS-PAGE with a molecular mass of almost 100 KD from control and infected mice. The kinetic studies of hepatic TAT towards its substrates showed no change in Km, whereas Vmax value was increased from 2.3 to 2.9 fold in the enzyme isolated from Schistsoma- infected mice. In addition, the Kcat/ Km ratio displayed a higher value for the enzyme from infected mice, indicating that it is more efficient and specific. On the other hand, the in vitro effect of praziquantel showed a slight activation of hepatic TAT in both control and infected mice, whereas mirazid (MZD) has an inhibitory effect in a concentration-dependent manner. The response of TAT from infected mice towards MZD inhibition is less than that from controls. These data suggest that there is a change in the catalytic properties of hepatic TAT in schistosomiasis and the in vitro effect of the schistosomicidal drugs appears to have inductive or inhibitory effect.
