Prevalence of Aggressive Behavior Toward Fellows, Residents, and Nurses at a Tertiary Care Hospital in Riyadh, Saudi Arabia.

Background Workplace bullying (WPB) is a form of mistreatment toward an individual manifested by physical, verbal, or indirect aggression. Affected victims display a wide range of signs and symptoms that impact their health. This study aimed to investigate the prevalence of aggressive behavior toward healthcare workers and its effects on job satisfaction, general health, and mental health. Methodology An online survey comprising a revised version of the Negative Acts Questionnaire-Revised (NAQ-R) was distributed to the fellows, residents, and nurses working in a tertiary care hospital. The survey collected information regarding the group's demographics and their exposure to WPB encountered in the work environment while maintaining confidentiality. Survey results were analyzed using SPSS Statistics version 25 (IBM Corp., Armonk, NY, USA). Results Among the 339 participants who filled the survey, 53% of healthcare practitioners in different services had experienced some form of WPB. Among the targeted group, it was noted that female gender (50%), age between 31 and 41 years (57.03%), nurses (51.98%), non-Saudi practitioners (41.94%), and those working in inpatient settings (49.74%) were the most commonly affected individuals in the medical facility. Furthermore, higher bullying prevalence was correlated with lower job satisfaction and mental health levels. Conclusions Age, gender, job, and nationality were factors associated with increased susceptibility to WPB. WPB in any facility is an unfortunate event, especially in a healthcare setting. It affects health practitioners by decreasing job satisfaction, jeopardizing health, and increasing the risk of harm to patients. WPB will eventually have a negative impact on the medical facility and the healthcare sector. Hence, hospital administrations should be alarmed about the rise in WPB, and adequate measures must be taken to deal with the root cause of the problem.

Transcatheter mitral valve-in-valve implantation for failed bioprosthesis.

OBJECTIVE: This study is a report of clinical and echocardiographic outcomes of experience with transapical mitral valve-in-valve (VIV) replacement. METHODS: Eleven patients with a mean age of 63.7±13.0 years who underwent transapical mitral VIV implantation for a failed bioprosthesis at a single institution were enrolled. All of the patients were considered high-risk for surgical intervention, with a Society of Thoracic Surgery predicted risk of mortality of 14.2±17.6%, and a mean European System for Cardiac Operative Risk Evaluation (EuroSCORE II) of 10.5±6.1%. RESULTS: Transapical mitral VIV implantation was successful in all of the patients. Edwards, Sapien XT and Sapien 3 valves (Edwards Lifesciences Corp., Irvine, CA, USA) were used in 8 (73%), 2 (18%), and 1 (9%) patients, respectively. Size 26 valves were used in 6 (55%) patients while size 29 valves were used in 5 (45%) patients. All of the patients (11, 100%) had no or only trace mitral regurgitation at the end of the procedure. The mean length of hospital stay was 19±8.0 days. The survival was 100% at 14 days, and 90% at 30 days and at 4 years. One patient died as a result of multiorgan failure on day 16 of intensive care unit stay. The mean mitral valve gradient across the percutaneous valve was 2.26±1.047 mmHg, and the mean valve area was 2.20±0.14 cm2. Through the 4 years follow up, the New York Heart Association class of the 10 patients remaining improved to class II with no readmission for heart failure. All of the patients were on coumadin with a target international normalized ratio of 2-3. CONCLUSION: In high-risk patients, transapical mitral VIV implantation can be performed with a high success rate and considerable improvement in clinical status.

Isolated Reoperative Tricuspid Valve Surgery: Outcomes and Risk Assessment.

OBJECTIVE: To describe patient characteristics and post-operative outcomes, including early and late mortality, defined by death within 30 days and after 30 days post-surgery, respectively, as well as 20-year survival after isolated reoperative tricuspid surgery. METHODS: We retrospectively analyzed 169 patients who underwent isolated reoperative tricuspid valve surgery at our institution (between 1997 and 2000) and describe post-surgical outcomes including intraoperative, early and late mortality. All patients included completed 21 years of follow-up. RESULTS: The majority of our patients were females 147 (87%) with the mean age of 45.9 ± 12.9 years. The mean body mass index (BMI, kg/m2) was 27.4 ± 6.0. Previous cardiac surgeries included tricuspid valve surgeries in 169 (100%) patients, with bioprosthetic valves, mechanical valves, annual rings and tricuspid repair surgeries utilized in 37 (21.9%), 21 (12.4%), 38 (22.4%) and 73 (43.2%) patients, respectively. The indication for previous tricuspid surgery was rheumatic heart disease in 154 (91.5%) patients.The most common cause of reoperative valvular surgery was tricuspid regurgitation (TR) in 139 (82.2%), with 66% of patients having severe TR. Other reasons for reoperative surgery included tricuspid stenosis 22 (13%) and dehiscence 8 (4.7%). For the redo surgery, 125 (74%) patients underwent Tricuspid Valve Replacement (TVR), 90 (53%) of whom received bioprosthetic valves while 35 (21%) received mechanical valves. Forty-four patients (26%) underwent Tricuspid Valve Repair. Mortality within 30 days of surgery was 11.3% (20 patients) and 11.4% after 30 days, with 20 years survival being about 80%. CONCLUSIONS: Based on our experience, reoperation for failed isolated tricuspid valve replacement or repair was associated with reasonable mortality and good survival rate over long period of time.

Cardiovascular Toxicity Associated With Tyrosine Kinase Inhibitor Therapy In Chronic Myeloid Leukemia.

Treatment of Chronic myeloid leukemia (CML) typically entails a long-term course of tyrosine kinase inhibitors (TKI) therapy. This review provides a summary on the cardiotoxic effects of TKIs. Five small molecular TKIs were evaluated in our review. The cardiotoxic effects of TKIs can range from superficial edema to potentially fatal conditions such as congestive heart failure (HF) and acute coronary syndrome (ACS). With the constant introduction of newer generations of TKIs, it has been demonstrated that different TKIs have distinct cardiovascular safety profiles. Amongst which, the first-generation TKI - imatinib appears to have the safest profile, mainly causing edema along with nausea, rash and muscle cramps. Other TKIs, like the second-generation dasatinib, bosutinib,and nilotinib, have shown an increased incidence of pleural effusion and QT prolongation. Ponatinib, a third generation TKI, has shown a relatively high incidence of serious adverse effects including thrombotic vascular occlusion and heart failure, particularly in patients with a prior history of cardiovascular impairment. Therefore, it is advisable that at-risk patients taking TKIs be screened with an Electrocardiogram (ECG) and have a careful cardiovascular risk assessment before starting TKI therapy to avoid potential cardiotoxic effects such as arrhythmias, acute coronary syndrome (ACS), congestive heart failure, and pleural effusion.

Outcomes of Routine Coronary Angiography in Asymptomatic Patients With End-Stage Renal Disease Prior to Kidney Transplantation.

We report the prevalence of coronary artery disease (CAD) in asymptomatic patients with end-stage kidney disease (ESKD) on hemodialysis and explore the best revascularization strategies prior to kidney transplantation. This is a retrospective single-center study, which included all patients who were candidates for kidney transplantation and underwent coronary angiography between 2003 and 2018. All included patients underwent coronary angiography without noninvasive testing and were asymptomatic cardiac-wise. Out of the 368 patients with ESRD, 45% had coronary vessel disease, 17% had 3-vessel disease, 11% had 2-vessel disease, 5.2% had significant left main artery narrowing, and 17% had single-vessel disease. Patients with 3-vessel disease had the worst survival rate at 5 and 10 years. The patients with significant 3-vessel disease or left main artery involvement underwent revascularization; 19% underwent coronary artery bypass grafting, 5% had stenting of the coronary arteries, and 4.7% were on maximal medical therapy. The patients who underwent stenting had a better survival than those on medical therapy, but the difference was not significant (P = .445). Our findings reflect a high prevalence of CAD in patients with ESKD. There is a need for further studies to evaluate benefits of cardiovascular screening in this patient population.
