RESUMO

BACKGROUND: Percutaneous Hepatic Perfusion (PHP) is a liver directed regional therapy recently FDA approved for metastatic uveal melanoma to the liver involving percutaneous isolation of liver, saturation of the entire liver with high-dose chemotherapy and filtration extracorporeally though in line filters and veno-venous bypass. The procedure is associated with hemodynamic shifts requiring hemodynamic support and blood product resuscitation due to coagulopathy. OBJECTIVE: To assess the cardiac safety and subsequent clinically significant sequalae of this therapy. METHODS: Consecutive PHP procedures done at our center between 2010-2022 were assessed retrospectively. Cardiac risk factors, post procedural cardiac enzymes, electrocardiograms, and transthoracic echocardiograms along with 90-day cardiac outcomes were reviewed. All data were reviewed by cardio-oncologists at our institution. RESULTS: Of 37 patients reviewed, mean age was 63 years and 57% were women. 132 procedures were performed with an average of 3.57 procedures per patient. 68.6% of patients had elevated troponin during at least 1 procedure. No patients were found to have acute coronary syndrome, heart failure, unstable arrhythmias, or cardiac death. No patients had notable echocardiographic changes. 10.8% of patients with positive troponin had asymptomatic transient electrocardiographic changes not meeting criteria for myocardial infarction. One patient had non-sustained ventricular tachycardiac intra-operatively which did not recur subsequently. Three patients died from non-cardiac causes within 90-days. There was no oncology treatment interruption, even in those with troponin elevation. In multivariable analysis, a history of hyperlipidemia was a predictor of postoperative troponin elevation. (P = .042). CONCLUSION: Percutaneous Hepatic Perfusion is safe and associated with a transient, asymptomatic troponin elevation peri-operatively without major adverse cardiac events at 90 days. The observed troponin elevation is likely secondary to coronary demand-supply mismatch related to procedural hemodynamic shifts, hypotension, and anemia.


Percutaneous hepatic perfusion using melphalan in patients with uveal melanoma and liver metastases carries no significant cardiac adverse events.

RESUMO

OPINION STATEMENT: There has been a significant shift in the management of B cell malignancies over the past decade. Initial strategies involving the use of systemic chemotherapies have been gradually replaced by more targeted therapies to improve survival and overall tolerability. Bruton's tyrosine kinase inhibitors are breakthrough drugs that have been approved to treat many B cell malignancies. Despite their demonstrated benefits, unintended events still occur including various cardiotoxicities. In this review, we discuss the rationale behind developing these agents, their common cardiovascular toxicities, and associated management challenges.

RESUMO

In this study, carbon species were grown on the surface of Ni-impregnated powder activated carbon to form a novel hybrid carbon nanomaterial by chemical vapor deposition. The carbon nanomaterial was obtained by the precipitation of the methane elemental carbon atoms on the surface of the Ni catalyst. The physiochemical properties of the hybrid material were characterized to illustrate the successful growth of carbon species on the carbon substrate. The response surface methodology was used for the evaluation of adsorption parameters effect such as pH, adsorbent dose and contact time on the percentage removal of MB dye from aqueous solution. The optimum conditions were found to be pH = 11, adsorbent dose = 15 mg and contact time of 120 min. The material we prepared showed excellent removal efficiency of 96% for initial MB concentration of 50 mg/L. The adsorption of MB was described accurately by the pseudo-second-order model with R2 of 0.998 and qe of 163.93 (mg/g). The adsorption system showed the best agreement with Langmuir model with R2 of 0.989 and maximum adsorption capacity (Qm) of 250 mg/g.

RESUMO

BACKGROUND: In the RadiCure study 505 catheterization procedures were 1:1 randomized to use or no use of real-time radiation monitoring. Use of the Bleeper Sv monitor resulted in a significant reduction in operator radiation exposure. METHODS: We examined the association between several baseline and procedural parameters with operator and patient radiation exposure using univariable and multivariable analysis in the 505 patients that were enrolled in RadiCure. All baseline demographic and procedure characteristics recorded were included in the univariable analysis. RESULTS: Median fluoroscopy time was 6.2 (2.5-12.5) minutes, median patient air kerma dose was 0.908 (0.602-1.636) Gray and median first operator exposure was 10 (5-22) µSv. For analysis purposes, the 505 procedures were dichotomized based on the median operator exposure (10 µSv) and median patient radiation dose (0.908 Gray). On multivariable analysis, factors associated with high (above median or >10 µSv) first operator radiation exposure included radial access (odds ratio [OR] 5.44, 95% Confidence Interval [CI] 2.88-10.76), chronic total occlusion (CTO) intervention (OR 12.78, 95% CI 4.42-43.60), real-time radiation monitoring (OR 0.42, 95% CI 0.26-0.66), and use of a radioabsorbent drape (OR 0.53, 95% CI 0.28-0.96). High patient radiation dose (above median or >0.908 Gray) was associated with body mass index>30 kg/m2 (OR 3.22, 95% CI 1.99-5.29), prior MI (OR 2.26, 95% CI 1.29-4.04), prior cerebrovascular disease (OR 0.34, 95% CI 0.15-0.75), hypertension (OR 2.40, 95% CI 1.05-5.82), prior coronary artery bypass graft surgery (OR 2.46, 95% CI 1.40-4.39) and CTO intervention (OR 12.93, 95% CI 3.28-87.31), but was not associated with real-time radiation monitoring and use of a radioabsorbent drape. CONCLUSIONS: Several clinical and procedural factors are associated with higher patient and operator radiation exposure. Real-time radiation monitoring and use of disposable radiation shields were associated with lower operator, but not patient, radiation dose. © 2015 Wiley Periodicals, Inc.

RESUMO

BACKGROUND: The impact of operator experience on fluoroscopy time and contrast utilization during percutaneous coronary intervention (PCI) of coronary chronic total occlusions (CTOs) has received limited study. METHODS: We evaluated temporal trends in fluoroscopy time and contrast utilization among 1,363 consecutive CTO PCIs performed at three US institutions between January 2006 and November 2011. RESULTS: Mean age was 65 ± 11 years, 85% of patients were men, 40% had diabetes, 37% had prior coronary artery bypass graft surgery, and 42% had prior PCI. The CTO target vessel was the right coronary artery (55%), circumflex (23%), left anterior descending artery (21%), and left main or bypass graft (1%). The retrograde approach was used in 34% of all procedures. The technical and procedural success rates were 85.5 and 84.2%, respectively. The mean procedural time, fluoroscopy time, and contrast utilization were 113 ± 61 min, 42 ± 29 min, and 294 ± 158 mL, respectively. Years since initiation of CTO PCI were independently associated with higher technical success rate (odds ratio [OR] = 1.52, 95% confidence interval [CI] = 1.52-1.70, P < 0.001), lower fluoroscopy time (OR = 0.84, 95% CI = 0.75-0.95, P = 0.005), and contrast utilization (OR = 0.84, 95% CI = 0.62-0.79, P < 0.001) during the study period. CONCLUSIONS: Among selected US-based institutions performing CTO PCI, we observed a significant reduction in total fluoroscopy time and contrast utilization paralleled with an improved technical success rate over time.

RESUMO

BACKGROUND: Optical coherence tomography (OCT) coronary imaging requires displacement of red blood cells from the vessel lumen. This is usually accomplished using radiographic contrast. Low molecular weight dextran has low cost and is safe in low volumes. In the present study, we compared dextran with contrast for coronary OCT imaging. METHODS: Fifty-one vessels in 26 patients were sequentially imaged using manual injection of radiographic contrast (iodixanol) and dextran. OCT images were analyzed at 1 mm intervals to determine the image clarity (defined as a visible lumen border > 270°) and to measure the lumen area and lumen diameter. To correct for the refractive index of dextran, the dextran area measurements were multiplied by 1.117 and the dextran length measurements were multiplied by 1.057. RESULTS: A total of 3,418 cross-sections (1,709 with contrast and 1,709 with dextran) were analyzed. There were no complications related to OCT imaging or to contrast or dextran administration. Clear image segments were observed in 97.0% vs. 96.7% of the cross-sections obtained with contrast and dextran, respectively (P = 0.45). The mean lumen areas were also similar: 6.69 ± 1.95 mm(2) with iodixanol vs. 7.06 ± 2.06 mm(2) with dextran (correlation coefficient 0.984). CONCLUSIONS: The image quality and measurements during OCT image acquisition are similar for dextran and contrast. Dextran could be used instead of contrast for OCT imaging, especially in patients in whom contrast load minimization is desired.

RESUMO

OBJECTIVES: We sought to determine the contemporary prevalence and management of coronary chronic total occlusions (CTO) in a veteran population. BACKGROUND: The prevalence and management of CTOs in various populations has received limited study. METHODS: We collected clinical and angiographic data in consecutive patients that underwent coronary angiography at our institution between January 2011 and December 2012. Coronary artery disease (CAD) was defined as ≥50% diameter stenosis in ≥1 coronary artery. CTO was defined as total coronary artery occlusion of ≥3 month duration. RESULTS: Among 1,699 patients who underwent angiography during the study period, 20% did not have CAD, 20% had CAD and prior coronary artery bypass graft surgery (CABG), and 60% had CAD but no prior CABG. The prevalence of CTO among CAD patients with and without prior CABG was 89 and 31%, respectively. Compared to patients without CTO, CTO patients had more co-morbidities, more extensive CAD and were more frequently referred for CABG. Percutaneous coronary intervention (PCI) to any vessel was performed with similar frequency in patients with and without CTO (50% vs. 53%). CTO PCI was performed in 30% of patients without and 15% of patients with prior CABG with high technical (82 and 75%, respectively) and procedural success rates (80 and 73%, respectively). CONCLUSIONS: In a contemporary veteran population, coronary CTOs are highly prevalent and are associated with more extensive co-morbidities and higher likelihood for CABG referral. PCI was equally likely to be performed in patients with and without CTO.

RESUMO

OBJECTIVE: To compare long-term clinical outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) using the retrograde and antegrade approach. BACKGROUND: There is limited long-term clinical outcomes data on the retrograde approach to CTO PCI. METHODS: We performed a retrospective analysis of the long-term clinical outcomes of 193 consecutive patients who underwent successful CTO PCI at our institution between March 2008 and December 2011. RESULTS: Mean age was 63.6 ± 8.3 years. The target vessel was right coronary artery in 52.6%, left anterior descending artery in 24.5% and circumflex in 21.4% of cases. The retrograde approach was used in 41 patients (21.2%). The mean stent length was longer in the retrograde group (83 ± 32 vs. 64 ± 32 mm, P = 0.001). Two major procedural complications occurred, both in the retrograde group (P = 0.012). During a median follow-up of 2.0 years compared to the antegrade CTO PCI group, patients who underwent retrograde CTO PCI were more likely to undergo target lesion revascularization (TLR) (45.6% vs. 25.7%, P = 0.006). No significant difference was observed in the incidence of all-cause mortality, myocardial infarction, non-target vessel revascularization, or coronary artery bypass graft surgery between the 2 groups. On multivariate analysis, stent length was the only independent predictor of TLR during follow-up. CONCLUSIONS: Retrograde CTO PCI was associated with higher incidence of TLR, but similar incidence of death and myocardial infarction compared to antegrade CTO PCI. These findings likely reflect the higher complexity of CTO lesions treated with the retrograde approach.

RESUMO

OBJECTIVE: To assess the outcomes of the "hybrid" approach to chronic total occlusion (CTO) percutaneous coronary interventions (PCIs). BACKGROUND: The "hybrid approach" to CTO PCI advocates appropriate and early change of crossing strategy to maximize success, safety, and efficiency. METHODS: We prospectively recorded and analyzed detailed step-by-step procedural data in 73 consecutive CTO PCI cases performed by a single operator between July 2011 and August 2012. RESULTS: Technical success was achieved in 66 of 73 cases (90.4%). Mean patient age was 65 ± 7 years, and 30% had prior coronary artery bypass surgery. Dual injection was used in 78%. The primary approach was retrograde in 9 cases (12.5%) and antegrade in 64 cases (87.5%), of whom 25 cases (39.1%) underwent retrograde attempt after failed antegrade approach. The initial crossing approach was successful in 40 cases (54.8%), but 32 cases (44%) required 3.6 ± 1.4 approach changes (range 2-7). Antegrade wire escalation, antegrade dissection/reentry, and retrograde crossing were utilized in 97.2%, 46.6%, and 46.6% of cases, respectively. Among successful cases, the final CTO crossing technique was antegrade wire escalation in 50.0%, antegrade dissection/reentry in 24.2%, and retrograde in 25.8%. The mean procedure time, fluoroscopy time, and air kerma radiation exposure until CTO crossing or stopping the procedure were 66 ± 55 minutes, 25 ± 23 minutes, and 2.3 ± 1.9 Gray, respectively. Three patients (4.1%) had a major complication. CONCLUSION: In the "hybrid approach" to CTO PCI, changes in crossing strategy were needed in approximately half the cases, resulting in high success and low complication rates.

RESUMO

Background Breast cancer (BC) is a global public health issue, contributing to a significant death toll among women. Breast cancer is the most common type among Saudi women, accounting for over a quarter of all new cancer cases. The current approaches for detecting BC include mammography, clinical breast exams, and breast self-examination (BSE). Early diagnosis of BC is crucial for reducing mortality and morbidity. This study aims to investigate attitudes and behaviors regarding early screening and self-examination of breast cancer in Saudi Arabia. Materials and method This cross-sectional study was conducted over eight months. The sample size calculation with a 95% confidence interval and 0.05 precision rate is 600 of the total targeted group. The study included Saudi females aged 30 and above. Data were collected via an online questionnaire. The questionnaire evaluated various aspects, including information regarding sociodemographics, barriers, and attitudes toward breast cancer screening. Results The majority of participants were aged 41-50 (40.7%) and married (76.2%). Over a third (31.9%) had been diagnosed with benign breast tumors, with MRI being the most common examination method (39.2%). Regarding screening practices, 55.7% had been screened previously, with a high intention for future screening (76.8%). Attitudes toward screening were positive, with 83.4% willing to undergo testing if free, painless, and conducted by a female provider. Barriers to screening included fear of examination (30.2%) and shame about exposing the body (25.6%). Conclusion The study provides valuable insights into the demographic characteristics, prevalence of benign breast tumors, screening practices, and attitudes toward breast cancer screening among Saudi women aged 30 and above. Factors such as age, marital status, income, occupation, and geographical residency influence screening behavior and intentions. Efforts to promote awareness, reduce barriers, and improve access to screening services are essential for enhancing breast cancer detection and prevention within this population.

RESUMO

Carbendazim (CBZ) is a widely used fungicide that is used to control the unwanted growth of fungi on fruits and vegetables. Sixty male rats were divided into six groups, each having ten. Group one served as control, animals belonging to group two were exposed to CBZ in the measure of 200 mg/kg body weight (BW). In the third and fourth groups, rats were administered 800 mg/kg BW of Moringa oleifera (moringa oil) and Linum usitatissimum L. (flaxseed oil), plus CBZ with the same dose given to group two. Groups five and six were administered with moringa and flaxseed oils respectively for six weeks. A marked decline was seen in oxidative stress markers, reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), and a rise in malondialdehyde (MDA) level in group two with severe histological disruptions. Moringa oil and flaxseed oil were used to alleviate these changes. In addition, a biocomputational molecular docking analysis of three proteins found in male rats was performed. In relation to CBZ (CID:10584007) the screened proteins namely testis-expressed protein (TX101_RAT), EPPI_RAT, and glutathione peroxidase 5 (GPX5_RAT) were docked, and their docking score were obtained (-5.9 kcal/mol), (-5.8 kcal/mol) and (-5.6 kcal/mol) respectively. By examining these interactions in 2D and 3D structures, a detailed understanding of the unique and specific binding affinity, hydrogen bonds, hydrophobic interactions, ionic bonds, and water bonds were obtained. Structure-based virtual screening (SBVS) molecular docking analysis showed that protein interaction with CBZ causes reproductive complications in protein expression and functions by hampering their normal function and blocking active sites.

RESUMO

As a treatment for relapsed or refractory multiple myeloma (MM), carfilzomib has been associated with a significant risk of cardiovascular adverse events (CVAE). The goals of our study were to evaluate the metabolomic profile of MM patients to identify those at high risk prior to carfilzomib treatment and to explore the mechanisms of carfilzomib-CVAE to inform potential strategies to protect patients from this cardiotoxicity. Global metabolomic profiling was performed on the baseline and post-baseline plasma samples of 60 MM patients treated with carfilzomib-based therapy, including 31 who experienced CVAE, in a prospective cohort study. Baseline metabolites and post-baseline/baseline metabolite ratios that differ between the CVAE and no-CVAE patients were identified using unadjusted and adjusted methods. A baseline metabolomic risk score was created to stratify patients. We observed a lower abundance of tauroursodeoxycholic acid (T-UDCA) in CVAE patients at baseline (odds ratio [OR] = 0.47, 95% confidence interval [CI] = 0.21-0.94, p = 0.044) compared with the no-CVAE patients. A metabolite risk score was able to stratify patients into three risk groups. The area under the receiver-operating curve of the model with clinical predictors and metabolite risk score was 0.93. Glycochenodeoxycholic acid (OR = 0.56, 95% CI = 0.31-0.87, p = 0.023) was significantly lower in post-baseline/baseline ratios of CVAE patients compared with no-CVAE patients. Following metabolomic analysis, we created a baseline metabolite risk score that can stratify MM patients into different risk groups. The result also provided intriguing clues about the mechanism of carfilzomib-CVAE and potential cardioprotective strategies.

RESUMO

OBJECTIVES: This study aims to identify various risk factors for acute peripancreatic fluid collections (APFCs) in patients presenting with acute pancreatitis (AP). METHODS: A blinded retrospective case-control study was conducted at a tertiary care hospital in Riyadh. Data from 327 patients who presented with AP between January 2008 and 2021 were analyzed. Following the application of inclusion/exclusion criteria, the final sample size consisted of 82 patients. Patients were divided into cases and controls based on the presence or absence of APFCs, respectively. APFCs were defined as fluid collections in the peripancreatic region that develop within four weeks of presentation without well-defined walls or solid internal components. Demographic, clinical, and laboratory variables were collected and subjected to multivariate binary regression analysis to assess the odds of developing APFCs. RESULTS: A total of 34 patients were categorized as cases, while 48 patients were controls. A significant association was found between age (P=0.022), total bilirubin (P=0.012), lipase level (P<0.001), albumin level (P=0.038), and lactate dehydrogenase (LDH) (P=0.037) on admission and the odds of developing APFCs. CONCLUSION: Older age, higher levels of bilirubin and lipase, and low levels of albumin and LDH were found to be risk factors for developing APFCs. No other variables were found to be significant. The findings of this study may provide insight into how often clinicians can expect APFCs in patients presenting with AP.

RESUMO

BACKGROUND: Chimeric antigen receptor T- Cell (CAR-T) immunotherapy has been a breakthrough treatment for various hematological malignancies. However, cardiotoxicities such as new-onset heart failure, arrhythmia, acute coronary syndrome and cardiovascular death occur in 10-15% of patients treated with CAR-T. This study aims to investigate the changes in cardiac and inflammatory biomarkers in CAR-T therapy to determine the role of pro-inflammatory cytokines. METHODS: In this observational study, ninety consecutive patients treated with CAR-T underwent baseline cardiac investigation with electrocardiogram (ECG), transthoracic echocardiogram (TTE), troponin-I, and B-type natriuretic peptide (BNP). Follow-up ECG, troponin-I and BNP were obtained five days post- CAR-T. In a subset of patients (N = 53), serum inflammatory cytokines interleukin (IL)-2, IL-6, IL-15, interferon (IFN)-γ, tumor necrosis factor (TNF)-α, granulocyte-macrophage colony-stimulating factor (GM-CSF), and angiopoietin 1 & 2 were tested serially, including baseline and daily during hospitalization. Adverse cardiac events were defined as new-onset cardiomyopathy/heart failure, acute coronary syndrome, arrhythmia and cardiovascular death. RESULTS: Eleven patients (12%) had adverse cardiac events (one with new-onset cardiomyopathy and ten with new-onset atrial fibrillation). Adverse cardiac events appear to have occurred among patients with advanced age (77 vs. 66 years; p = 0.002), higher baseline creatinine (0.9 vs. 0.7 mg/dL; 0.007) and higher left atrial volume index (23.9 vs. 16.9mL/m2; p = 0.042). Day 5 BNP levels (125 vs. 63pg/mL; p = 0.019), but not troponin-I, were higher in patients with adverse cardiac events, compared to those without. The maximum levels of IL-6 (3855.0 vs. 254.0 pg/mL; p = 0.021), IFN-γ (474.0 vs. 48.8pg/mL; p = 0.006) and IL-15 (70.2 vs. 39.2pg/mL; p = 0.026) were also higher in the adverse cardiac events group. However, cardiac and inflammatory biomarker levels were not associated with cardiac events. Patients who developed cardiac events did not exhibit worse survival compared to patients without cardiac events (Log-rank p = 0.200). CONCLUSION: Adverse cardiac events, predominantly atrial fibrillation, occur commonly after CAR-T (12%). The changes in serial inflammatory cytokine after CAR-T in the setting of adverse cardiac events suggests pro-inflammation as a pathophysiology and require further investigation for their role in adverse cardiac events.

RESUMO

Idecabtagene vicleucel (ide-cel) is a type of B-cell maturation antigen (BCMA)-targeting chimeric antigen receptor T-cell (CAR-T) approved for the treatment of relapsed and refractory multiple myeloma (RRMM). Currently, the incidence of cardiac events associated with ide-cel remains unclear. This was a retrospective single-center observational study of patients treated with ide-cel for RRMM. We included all consecutive patients who received standard-of-care ide-cel treatment at least 1-month follow-up. Baseline clinical risk factors, safety profile, and responses were examined based on the development of a cardiac event. A total of 78 patients were treated with ide-cel, and 11 patients (14.1%) developed cardiac events: heart failure (5.1%), atrial fibrillation (10.3%), nonsustained ventricular tachycardia (3.8%), and cardiovascular death (1.3%). Only 11 of the 78 patients had repeat echocardiogram. Baseline risk factors associated with the development of cardiac events included being female sex and having poor performance status, λ light-chain disease, and advanced Revised International Staging System stage. Baseline cardiac characteristics were not associated with cardiac events. During index hospitalization after CAR-T, higher-grade (≥grade 2) cytokine release syndrome (CRS) and immune cell-associated neurologic syndrome were associated with cardiac events. In multivariable analyses, the hazard ratio for the association of the presence of cardiac events with overall survival (OS) was 2.66 and progression-free survival (PFS) was 1.98. Ide-cel CAR-T for RRMM was associated with similar cardiac events as other types of CAR-T. Worse baseline performance status and higher-grade CRS and neurotoxicity were associated with cardiac events after BCMA-directed CAR-T-cell therapy. Our results suggest that the presence of cardiac events may confer worse PFS or OS; although because of the small sample size, the power to detect an association was limited.

RESUMO

Background: Regional variations in cardiovascular disease (CVD) and CVD management are well known. However, there is limited information on geographical variations in the discipline of Cardio-Oncology, including both the nature of CVD in patients with cancer and its management. Furthermore, during the recent COVID-19 pandemic, CV care for patients was disrupted resulting in an unknown impact on cardio-oncology services. Objective: The aim of this study was to identify the regional variations in the management of CVD among patients with cancer and the impact of the COVID-19 pandemic on the selection of cardiovascular drugs in cardio-oncology. Methods: An online survey was conducted by the Iraq Chapter of the International Cardio-Oncology Society (IC-OS). The survey was shared with cardiologists and oncologists in all seven continents to identify whether regional variations exist in cardio-oncology daily practice. Results: From April to July 2021, 140 participants responded to the survey, including cardiologists (72.9%) and oncologists (27.1%). Most of the respondents were from the Middle East (26.4%), North America (25%), Latin America and the Caribbean (25%), and Europe (20.7%). Baseline CV risk assessment in patients with cancer using the HFA/IC-OS score was reported in 75.7% of respondents (78.4% cardiologists and 68.4% oncologists). Hypertension was the most common CVD treated by the survey respondents globally (52.1%) unlike in Europe where heart failure was the most prominent CVD (51.7%). The blood pressure cutoff value to initiate hypertension management is >140/90 mmHg globally (72.9%), but in North America (48.6%) it was >130/80 mmHg. In the Middle East, 43.2% of respondents do not use cardioprotective medication. During the COVID-19 pandemic, 10.7% of respondents changed their practice, such as switching from prescribing ACEI to ARB. Apixaban is the main anticoagulant used in patients with cancer (32.9%); however, in cancer patients with COVID-19 infection, the majority used enoxaparin (31.4%). Conclusion: More than three-quarters of cardiologists and oncologists responding to the survey are using HFA/IC-OS proformas. The survey showed regional variations in the management of CVD on different continents. The use of cardioprotective agents was limited in some regions including the Middle East. COVID-19 pandemic impacted daily practice on the selection and switching of cardiovascular drugs including ACEI/ARB and the choice of anticoagulants.

RESUMO

Malathion (MAL) is an insecticide that has been linked to reproductive system damage in both humans and animals. In the present investigation, the antitoxic effects of coffee and olive oils on MAL-induced testicular dysfunctions were evaluated. MAL-intoxicated rats were supplemented with coffee and olive oils (400 mg/kg) for 7 weeks. Exposure to MAL resulted in statistically altered antioxidant enzymes and histopathological findings of necrotic seminiferous tubules and spermatogenetic arrest in rats after seven weeks of treatment. The effects of MAL intoxication on physiological and histopathological changes were improved by the use of these oils. Murine double minute 2 (MDM2) was found to interact well with chlorogenic acid and oleuropein, two compounds from coffee and olive oils, respectively. Coffee oil and olive oil were found to be promising therapeutic agents for MAL-induced testicular toxicity and oxidative damage.

RESUMO

Introduction  Ankylosing spondylitis, now frequently referred to as spondyloarthritis (SpA), is a chronic inflammatory disease causing axial arthritis and inflammatory lower back pain resulting in the eventual impairment of spinal mobility. Moreover, its systemic complications include stiffness and inflexibility, restriction of lung capacity and function, eye inflammation, compression spinal fractures, and heart problems. Hence, early diagnosis and intervention play a key role in preventing acute complications and improving the quality of life. Objective  We aimed to estimate the average duration of diagnosis, the average number of doctors visited, and the association between the specialty of the first physician and the length of SpA diagnosis delay. Methods A cross-sectional retrospective study was conducted from November 2019 to April 2020 with patients from King Khalid University Hospital, Riyadh, Saudi Arabia. The patients were 18 years and older and diagnosed with SpA. Call interviews were conducted and patients' medical charts were reviewed. The data were analyzed using the Statistical Package for Social Sciences statistical software, version 23 (IBM Corp., Armonk, NY). Result  The total sample was 101 patients: 59 (58.4%) males and 42 (41.6%) females. The average duration from the onset of symptoms until seeking medical advice (lag 1) and from seeking medical advice until the definite diagnosis (lag 2) was 24.74 ± 48.13 and 16.16 ± 34.62 months, respectively. The average number of doctors visited between the first medical encounter and the final diagnosis was 3.56 ± 5.3. Patients who consulted rheumatologists as the first medical encounter showed less delay in diagnosis compared to patients who sought non-rheumatologists, such as orthopedists, emergency physicians, and general physicians (11.81 ± 33.35 months vs. 26.63 ± 44.28, 26.96 ± 44.88, and 44.33 ± 65.75 months, respectively). Conclusion  Patients with SpA who were not seen by rheumatologists took a longer period till the final diagnosis than those who visited rheumatologists earlier in the course of the disease. Therefore, more studies are required to define the exact factors leading to the delay.

RESUMO

OBJECTIVES: To calculate the incidence of acute peripancreatic fluid collection (APFC) in patients with acute pancreatitis. The secondary objective is to determine the underlying etiologies of acute pancreatitis in the Saudi population. METHODS: A retrospective cohort study was carried out at King Khalid University Hospital, King Saud University, Riyadh, Saudi Arabia. The study analyzed data from patients who were diagnosed with acute pancreatitis between January 2008 and January 202. A total of 327 were included in the study after applying the inclusion and exclusion criteria. Their medical records were subsequently reviewed for the presence or absence of APFC on follow-up imaging studies, evidence of biliary stones, prior endoscopic retrograde cholangiopancreatography (ERCP), a history of alcohol use, and demographic variables. RESULTS: Of the 327 patients with acute pancreatitis, 158 (48.3%) developed APFC, while 169 (51.7%) did not. The majority of patients had an idiopathic etiology of acute pancreatitis (n=251; 76.8%); followed by a biliary etiology (n=51; 15.6%); post-ERCP complications (n=14; 4.3%), and other causes (n=11; 3.3%). CONCLUSION: The incidence of APFC in patients presenting with acute pancreatitis between January 2008 and January 2021 was 48.3%. The most common etiology of acute pancreatitis in this tertiary care hospital was idiopathic, followed by biliary etiologies and post-ERCP complications. More studies targeting the local complications of pancreatitis are needed to reach more definitive findings.
