Slowing the Tide of Alcohol Use Disorders.

Alcohol use disorders (AUDs)-a spectrum including at-risk drinking, alcohol abuse, dependence, and addiction-is a highly prevalent problem worldwide with a substantial economic impact. The toll of alcohol on individual health and healthcare systems is devastating. Alcohol is estimated to be the fifth leading risk factor for global disability-adjusted life years. Tackling the problem of AUD requires a comprehensive strategy that includes solid action on price, availability, and marketing of alcohol. Restricting or banning alcohol advertising may reduce exposure to the risk posed by alcohol at the individual and general population level. Warning labels about the cancer risks associated with drinking have a high degree of public support and may be an inexpensive and acceptable way to educate the public. Religiosity may reduce risk behaviors and contribute to health decision making related to alcohol use.

Ethical Dilemmas at the End of Life: Islamic Perspective.

Many Muslim patients and families are often reluctant to accept fatal diagnoses and prognoses. Not infrequently, aggressive therapy is sought by the patient or his/her family, to prolong the life of the patient at all costs. A series of searches were conducted of Medline databases published in English between January 2000 and January 2015 with the following Keywords: End-of-life, Ethics and Islam. Islamic law permits the withdrawal of futile treatment, including all kinds of life support, from terminally ill patients leaving death to take its natural course. However, such decision should only take place when the physicians are confident that death is inevitable. All interventions ensuring patient's comfort and dignity should be maintained. This topic is quite challenging for the health care providers of Muslim patients in the Western World.

Pragmatic message to junior doctors.

Although several studies described the experience of doctors in their first postgraduate years, few shed the light on the ethical issues encountered by them. These doctors face a broad range of 'everyday' ethical challenges, from breach of confidentiality to truth-telling or improper informed consent. The daily ethical issues faced by junior doctors are not as dramatic as the major issues learned at medical school. Junior doctors have to make the best ethical decisions within the time limits available. Undergraduate medical ethics curricula should give priority to the real-life issues that doctors will face in their first years of practice.

Real time three-dimensional transesophageal echocardiography: a novel approach for the assessment of prosthetic heart valves.

OBJECTIVES: To explore our initial experience with real time three-dimensional transesophageal echocardiography (RT3DTEE) for the assessment of prosthetic valves (PV). METHODS: The study included 40 patients (mean age 35 ± 8.5 years, 68% male) who underwent PV implant. Fifty PV (34 bioprosthetic and 16 mechanical) were evaluated using two-dimensional (2D)TEE and RT3DTEE to rule out PV dysfunction. RESULTS: In all patients, RT3DTEE allowed good and simultaneous visualization of PV leaflets. Ten patients had normal functioning PV (5 in mitral, 3 in aortic, and 2 in tricuspid positions). Infective endocarditis was evident in 13 patients (20 PV) by repeated 2DTEE. RT3DTEE confirmed the 2DTEE diagnosis of endocarditis in same patients. Clear delineation of vegetations (size, site, and number) was obtained from RT3DTEE full volume while the vegetation attachment, consistency, mobility and its relation to valve structure were obtained using zoom 3D. Paraaortic abscesses size, site, extension, wall thickness of the abscess could be identified by RT3DTEE in 7 PV. Through cropping of the full-volume 3D images, the orifice of communication between the abscess cavity and aorta could be visualized well in en face view. Color full-volume allowed the detection of paravalvular regurgitation (size, location, direction, and extent) in 8 patients. In the 18 PV who underwent redo surgery, the intra-operative findings confirmed the RT3DTEE description of PV lesions. CONCLUSION: Real time 3DTEE improved the anatomical and functional assessment of PV with better understanding of the underlying causes of PV dysfunction; hence, it could improve the management planning for such patients.

Ethical challenges of deactivation of cardiac devices in advanced heart failure.

More than 23 million adults worldwide have heart failure (HF). Although survival after heart failure diagnosis has improved over time, mortality from heart failure remains high. At the end of life, the chronic HF patient often becomes increasingly symptomatic, and may have other life-limiting comorbidities as well. Multiple trials have shown a clear mortality benefit with the use of implantable cardioverter defibrillators (ICDs) in patients with cardiomyopathy and ventricular arrhythmia. However, patients who have an ICD may be denied the chance of a sudden cardiac death, and instead are committed to a slower terminal decline, with frequent DC shocks that can be painful and decrease the quality of life, greatly contributing to their distress and that of their families during this period. While patients with ICDs are routinely counseled with regard to the benefits of ICDs, they have a poor understanding of the options for device deactivation and related ethical and legal implications. Deactivating an ICD or not performing a generator change is both legal and ethical, and is supported by guidelines from both sides of the Atlantic. Patient autonomy is paramount, and no patient is committed to any therapy that they no longer wish to receive. Left ventricular assist devices (LVADs) were initially used as bridge in patients awaiting heart transplantation, but they are currently implanted as destination therapy (DT) in patients with end-stage heart failure who have failed to respond to optimal medical therapy and who are ineligible for cardiac transplantation. The decision-making process for initiation and deactivation of LVAD is becoming more and more ethically and clinically challenging, particularly for elderly patients.

Real-time three-dimensional transthoracic echocardiography in daily practice: initial experience.

AIM OF THE WORK: To evaluate the feasibility and possible additional value of transthoracic real-time three-dimensional echocardiography (RT3D-TTE) for the assessment of cardiac structures as compared to 2D-TTE. METHODS: 320 patients (mean age 45 ± 8.4 years, 75% males) underwent 2D-TTE and RT3D-TTE using 3DQ-Q lab software for offline analysis. Volume quantification and functional assessment was performed in 90 patients for left ventricle and in 20 patients for right ventricle. Assessment of native (112 patients) and prosthetic (30 patients) valves morphology and functions was performed. RT3D-TTE was performed for evaluation of septal defects in 30 patients and intracardiac masses in 52 patients. RESULTS: RT3D-TTE assessment of left ventricle was feasible and reproducible in 86% of patients while for right ventricle, it was (55%). RT3D-TTE could define the surface anatomy of mitral valve optimally (100%), while for aortic and tricuspid was (88% and 81% respectively). Valve area could be planimetered in 100% for the mitral and in 80% for the aortic. RT3D-TTE provided a comprehensive anatomical and functional evaluation of prosthetic valves. RT3D-TTE enface visualization of septal defects allowed optimal assessment of shape, size, area and number of defects and evaluated the outcome post device closure. RT3D-TTE allowed looking inside the intracardiac masses through multiple sectioning, valuable anatomical delineation and volume calculation. CONCLUSION: Our initial experience showed that the use of RT3D-TTE in the assessment of cardiac patients is feasible and allowed detailed anatomical and functional assessment of many cardiac disorders.

Incremental utility of real time three-dimensional tranthoracic echocardiography in the assessment of congenitally malformed aortic valve.

OBJECTIVES: To study the feasibility and additional value of real time three-dimensional transthoracic echocardiography (RT3D-TTE) for anatomical and functional assessment of malformed aortic valve (AV) compared to conventional two-dimensional TTE (2D-TTE). METHODS: Malformed AV was evaluated in 35 patients (mean age 18 ± 9.5 years, 70% male) by both 2D-TTE and RT3D-TTE. The anatomical definition of aortic cusps (number, direction, and commissures) was evaluated by a 3-point visualization score (1: nonvisualized, 2: inadequate, 3: adequate). 2D-TTE and RT3D-TTE measurements included AV area and maximum diameters of both AV annulus and left ventricular outflow tract (LVOT). RESULTS: Adequate visualization of AV cusps was achieved in 86% of patients by RT3D-TTE compared to 63% by 2D-TTE. The mean and median visualization score obtained by RT3D-TTE were higher than that by 2D-TTE. The opening of commissures was detected in (80%) of patients by RT3D-TTE compared to (34%) by 2D-TTE. AV area planimetry could be obtained in 77% of patients by RT3D-TTE compared to 43% by 2D-TTE. RT3D-TTE visualization score of AV cusps and commissures showed better interobserver agreement (Kappa: 0.62 and 0.72, respectively) than 2D-TTE (0.58 and 0.69, respectively). RT3D-TTE and 2D-TTE measurements of AV annulus and LVOT were well correlated (r = 0.85; P < 0.001) but the RT3D-TTE measurements were significantly larger than that obtained by 2D-TTE (2.05 ± 0.7 cm and 2.5 ± 0.86 cm vs 1.94 ± 0.67 cm and 1.98 ± 0.74 cm; P < 0.01). CONCLUSION: RT3D-TTE is a feasible technique that allows comprehensive quantitative and qualitative assessment of malformed AV.

Organized intrapericardial haematoma: a rare cause of heart failure after 2 years of trauma.

Intrapericardial organized haematoma secondary to blunt chest trauma is an extremely rare cause of constrictive pericarditis. We report a 30-year-old male who presented with heart failure for 12 months and was found to have an organized intrapericardial haematoma secondary to blunt chest trauma in a road traffic accident 2 years prior. The use of multiple imaging modalities including two-dimensional (transthoracic and transoesophageal) echocardiogram and cardiac magnetic resonance imaging established the diagnosis. Surgical excision of the haematoma and removal of the constricting pericardium relieved his symptoms.

An incidental finding of mitral valve network.

A 63-year-old male presented with a 6-month history of worsening exertional dyspnea and was found to have three-vessel coronary artery disease. Transesophageal echocardiography revealed a filamentous structure attached to the anterior mitral valve leaflet, which was confirmed during surgery as filamentous network. To our knowledge, this is the first report to describe such a network attached to the mitral valve.

Right atrial metastasis mimicking myxoma in advanced hepatocellular carcinoma.

Hepatocellular carcinoma is the most common primary tumor of the liver accounting for 4.6% of all new human cancers. Cardiac metastasis in hepatocellular carcinoma is an uncommon secondary cardiac malignancy. We described two cases of advanced hepatocellular carcinoma with large masses in the right atrium mimicking atrial myxoma. The RA masses were incidentally detected during two-dimensional echocardiographic examination.

Ethical dilemmas in the era of COVID-19.

The coronavirus disease 2019 (COVID-19) pandemic placed an extraordinary demand on health systems and healthcare providers all over the world. The pandemic presented a number of unprecedented challenging ethical issues. Across the globe, hospitals are being challenged by a large number of patients presenting to the emergency room for treatment, creating scarcities of critical care resources, and uncovering the need for formal crisis standards of care. Difficult life and death decisions, which may create severe moral distress to the physicians, have to be made in emergency rooms and intensive care units. Other ethical issues, such as that related to conducting clinical trials during the pandemic, and the increase in domestic violence during the quarantine period, will be also discussed.

Real-time three-dimensional echocardiographic assessment of inferior vena caval thrombosis.

Inferior vena cava thrombosis (IVCT) represents a subset of deep venous thrombosis. Because of the variety of its clinical presentations, the exact incidence is elusive. We present two cases of IVCT that was incidentally discovered during a routine two-dimensional echocardiography. Real-time three-dimensional echocardiography (RT3DE) assessment of IVCT added more valuable information that may help in its management. To the best of our knowledge, this is the first case report using RT3DE in the assessment of IVCT.

Right atrial myxoma associated with an atrial septal defect by real-time three-dimensional echocardiography.

A 40-year-old woman presented with a 1 month history of shortness of breath and easy fatigability. Two-dimensional echocardiography and real-time three-dimensional echocardiography (RT3DE) showed a large right atrial mass protruding into the right ventricle and an atrial septal defect (ASD). Successful excision of the mass, which proved to be a myxoma, and closure of the ASD completely relieved her symptoms. To our knowledge, this is the first report of RT3DE in a patient with right atrial myxoma associated with an ASD.

Imaging of ventricular septal tumor in an asymptomatic adolescent using multiple modalities.

Primary cardiac tumors are rare at all ages, and especially so in childhood, where the most prevalent type of benign cardiac masses are rhabdomyomas followed by fibromas, both of which have a predilection for ventricular septum. We report an unusual case of a tumor involving the ventricular septum in an asymptomatic 17-year-old adolescent who has been known to have this tumor for 10 years. The use of multiple imaging included myocardial contrast two-dimensional echocardiography, real time three-dimensional echocardiography (with and without myocardial contrast), and magnetic resonance imaging supported the diagnosis of cardiac rhabdomyoma.

"Hanging by a thread" left ventricular thrombus in an asymptomatic soldier.

A mobile and pedunculated left ventricular mass was incidentally detected on transthoracic echocardiography in a 32-year old asymptomatic soldier. Because of the mobility of the mass and the uncertainty of its nature, the risk of embolization was considered to be high, and hence surgical removal was recommended but the patient opted for anticoagulation therapy. The mass resolved within 6 weeks without any embolic or bleeding complications. No recurrence of the thrombus was observed during a 12-month follow up period.

Bicaval obstruction complicating right atrial tuberculoma: the diagnostic value of cardiovascular MR.

Cardiac tuberculosis is rare and usually involves the pericardium. Myocardial tuberculoma is a very rare occurrence and only a few cases were reported. We describe the use of cardiovascular magnetic resonance in the diagnosis of a rare case of cardiac tuberculoma involving the right atrium which was complicated by a bicaval obstruction. The patient made a remarkable improvement with the anti-tuberculous treatment. To our knowledge, this complication has never been reported in relation to cardiac tuberculoma.

Effects of Ramadan fasting on the symptoms of chronic heart failure.

OBJECTIVES: To investigate the effect of Ramadan fasting on the symptoms of chronic heart failure with a reduced ejection fraction (HFrEF). Globally, more than one billion Muslims fast during Ramadan. Data regarding the effect of fasting in heart failure patients with a reduced ejection fraction are limited. METHODS: We prospectively studied 249 outpatients with HFrEF who undertook Ramadan fasting at tertiary care cardiac center in Saudi Arabia in 2017. We obtained information regarding the clinical assessment, diagnosis, emergency department visits, and hospitalization during and in the month preceding Ramadan. RESULTS: We enrolled 249 patients, 227 (91%) undertook the fast for the entire month. During Ramadan, 209 (92%) patients remained hemodynamically stable, whereas 18 (8%) developed instability. The mean New York Heart Association (NYHA) functional class was significantly lower in the stable than in the unstable group (1.46±0.7 vs. 3.22±0.55, p less than 0.0001), although no intergroup differences were observed before Ramadan. Patients from the unstable vs. the stable group showed significantly less adherence to medications (67% vs. 94%, p less than 0.0001) and to diet (39% vs. 79%, p less than 0.0001), and a lower likelihood of demonstrating ischemic cardiomyopathy as an underlying etiology of HFrEF (33% vs. 57%, p=0.046). Dependent t-test analysis including all patients showed that the NYHA classification before Ramadan was significantly higher than during Ramadan (2.19±0.9 vs. 1.6±0.8, t-value 8.5, p less than 0.0001). CONCLUSION: In most patients with chronic HFrEF, Ramadan fasting is considered safe. Non-adherence to medication and diet are significantly associated with decompensated heart failure during Ramadan.

Do not resuscitate, brain death, and organ transplantation: Islamic perspective.

Muslim patients and families are often reluctant to discuss and accept fatal diagnoses and prognoses. In many instances, aggressive therapy is requested by a patient's family, prolonging the life of the patient at all costs. Islamic law permits the withdrawal of futile treatment, including life support, from terminally ill patients allowing death to take its natural course. "Do not resuscitate" is permitted in Islamic law in certain situations. Debate continues about the certainty of brain death criteria within Islamic scholars. Although brain death is accepted as true death by the majority of Muslim scholars and medical organizations, the consensus in the Muslim world is not unanimous, and some scholars still accept death only by cardiopulmonary criteria. Organ transplantation has been accepted in Islamic countries (with some resistance from some jurists). Many fatwas (decrees) of Islamic Jurisprudence Councils have been issued and allowed organs to be donated from living competent adult donor; and from deceased (cadavers), provided that they have agreed to donate or their families have agreed to donate after their death (usually these are brain-dead cases). A clear and well-defined policy from the ministry of health regarding do not resuscitate, brain death, and other end-of-life issues is urgently needed for all hospitals and health providers in most (if not all) Muslim and Arab countries.

Minimizing nocebo effect: Pragmatic approach.

The nocebo effect, the inverse of the placebo effect, is a well-established phenomenon, yet under-appreciated. It refers to nonpharmacological, harmful, or undesirable effects occurring after active or inactive therapy. The frequency of adverse events can dramatically increase by informing patients about the possible side effects of the treatment, and by negative expectations on the part of the patient. Patients who were told that they might experience sexual side effects after treatment with ß-blocker drugs reported these symptoms between three and four times more often than patients in a control group who were not informed about these symptoms. Nocebo effect has been reported in several neurological diseases such as migraine, epilepsy, multiple sclerosis, Parkinson's disease and neuropathic pain, and in patients with depression. The investigation of the biological and theoretical underpinning of the nocebo phenomenon is at an early stage, and more research is required. Physicians need to be aware of the influence of nocebo phenomenon and be able to recognize it and minimize its effects.
