Safety of ultra-low contrast coronary angiography in patients with acute kidney injury.

BACKGROUND: Ultra-low contrast administration during coronary angiography has been previously shown to be feasible and safe among patients with stable chronic kidney disease. In the present study, we investigate the safety of ultra-low contrast coronary angiography in patients with pre-existing acute kidney injury (AKI). METHODS: The study was a retrospective single-center evaluation of hospitalized patients who had AKI and required coronary angiography. Ultra-low contrast use was defined as ≤18 mL of contrast media. RESULTS: The cohort consisted of a case series of eight inpatients with AKI who required coronary angiography. The mean age was 57 (±16) years and half were females. All patients had chronic kidney disease with a mean baseline estimated glomerular filtration rate of 34 (±17) mL/min/1.73 m2. The mean creatinine before angiography was 3 (±1) mg/dL and volume of contrast administered was 14 (±4) mL. One patient had a 0.1 mg/dL increase in creatinine during admission, and no patients had further AKI up to 1-week postprocedure. CONCLUSIONS: The current data suggest that ultra-low contrast coronary angiography can be safely performed in patients with pre-existing AKI The study should be viewed as hypothesis-generating due to its small sample size. A larger cohort is required to validate the results.

Prevalence of adult attention deficit hyperactivity disorder (ADHD) among medical students in the Eastern Province of Saudi Arabia.

OBJECTIVES: To determine and compare the prevalence of attention deficit hyperactivity disorder (ADHD) symptoms among male and female medical students in the Eastern Province of Saudi Arabia and evaluate the effect of ADHD on the academic performance of the affected medical students. METHODS: This cross-sectional study measured the prevalence of adult ADHD symptoms among medical students in the Eastern Province of Saudi Arabia. A total of 354 Saudi medical students from King Faisal University, Al-Ahsa, and Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia, participated in a self-reported questionnaire. The questionnaire was distributed on different social media platforms from December 2021 to April 2022. RESULTS: Among the study participants, 26% exhibited symptoms highly consistent with adult ADHD. Young age (<20 years, p=0.049) and non-marital status (p=0.048) were associated with a higher rate of ADHD symptoms with recorded statistical significance. Additionally, there is no significant association between grade point average and adult ADHD (p=0.560). CONCLUSION: The study demonstrated a higher prevalence of adult ADHD among medical students in the Eastern Province than the reported rates locally and globally. This could be attributed to social and cultural factors, as well as the chosen method for assessing the symptoms of Diagnostic and Statistical Manual items.

Percutaneous debulking of tricuspid valve infective endocarditis vegetations using a large bore manual aspiration device - AlphaVac.

Most infectious endocarditis patients can be managed medically. However, non-responders to antibiotics and ongoing sequelae such as septic emboli, may require mechanical interventions. AngioVac (Angiodynamics, Latham, NY, USA) is a percutaneous aspiration device used for removal of thrombi, emboli, masses, and vegetations. Main drawbacks are the requirement for a perfusionist, two large-bore accesses, and meticulous de-airing. These drawbacks make the procedure more time-consuming and possibly increase the risk of complications. AlphaVac (Angiodynamics) omits the motor element, thereby overcoming several of the limitations. In the current report, we describe two cases of percutaneous aspiration of tricuspid valve vegetations using AlphaVac. Learning objective: To consider manual percutaneous aspiration of infective valvular vegetations using the AlphaVac cannula in case of insufficient response to antibiotics or for prevention of emboli.

Factors associated with the prevalence of depression and anxiety among parents of children with neurodevelopmental disorders in Saudi Arabia.

BACKGROUND: Neurodevelopmental disorders (NDDs) are a group of conditions that include attention-deficit/hyperactivity disorders, specific learning disorders, autism spectrum disorder, intellectual disability, and other disorders. Raising a child with an NDD can be difficult because it affects the social lives of the parents and their relationships. It also requires the parents to develop another set of skills to deal with their child. These factors increase their risk of depression and anxiety. AIM: To measure the prevalence rates of depression and anxiety among parents of children with different NDDs, compare the rates between mothers and fathers, and measure the relevant associated factors. METHODOLOGY: This study was a prospective, qualitative, cross-sectional, anonymous questionnaire-based study. The participants were 416 parents of children with NDDs in Saudi Arabia. The sample size was determined using the Richard Geiger equation with a 5% margin of error, a 95% confidence level, and a 50% response distribution. The screening was performed using a validated Arabic version of the Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7). These are short and understandable screening tools that assist in identifying and grading the severity of depression and anxiety symptoms. The participants were reached by distributing the questionnaire to parents who followed up with Saudi NDD-related associations, clinics, and psychiatric clinics from November 20 to May 8, 2022. The data were collected, reviewed, and then entered into SPSS 21. RESULTS: In total, 416 parents of children with NDDs in Saudi Arabia participated in the study. We demonstrated that 85.1% of parents of children with NDDs had depression and that 85.8% had anxiety. Mothers and fathers had similar rates of depression and anxiety. No significant difference was found between the type of NDD and rates of depression and anxiety in parents. CONCLUSION: Children with NDDs affect their parents' mental health in terms of increased rates of depression and anxiety. This increase is not correlated with a specific etiology. Healthcare professionals who care for children with NDDs should also assess parental mental health and seek an early diagnosis of mental illness to ensure that the appropriate interventions are provided for parents.

Hybrid approach to postmyocardial infarction ventricular septal defect repair.

Postinfarction ventricular septal rupture is a rare and devastating complication of myocardial infarction. Despite attempts at acute surgical and percutaneous defect closure, morbidity and mortality remain high. Herein, we describe a hybrid surgical and catheter-based approach to defect closure in a 63-year-old woman with postinfarction ventricular septal rupture and cardiogenic shock.

Mental Stigma Among Al-Ahsa Population in Saudi Arabia.

Introduction Mental stigma is when patients of mental illness are labeled by their disorders, viewed negatively, and discriminated against due to their illness. This has a big impact on people's attitudes and behaviors toward the mentally ill. Moreover, mental stigma leads people to avoid patients with mental health issues, blame them for their conditions, and associate them with negative features like being dangerous, unpredictable, and hard to communicate with. The primary objective of this study is to assess the mental stigma among the population of the Al-Ahsa region in Saudi Arabia. Methods This is a cross-sectional study conducted in Al-Ahsa, Saudi Arabia, between June and August 2021. The target population of the study was people aged 18-65 years old whose place of residency during the time of the study was Al-Ahsa. The questionnaire used in this study contained a mental stigma scale called community attitudes toward mental illness (CAMI). Results A total of 758 participants were enrolled in the study. The mean of the stigma score was 99.24 ± 15.622, with a minimum of 53 and a maximum of 176. The means of the subscales were as follows: authoritarianism (26.18 ± 4.420), benevolence (23.26 ± 4.762), community mental health ideology (24.66 ± 5.896), and social restrictiveness (25.13 ± 4.6). There was a positive relationship between age and stigma score. Healthcare workers were found to have a lower level of stigma, as were those who spoke more languages. Also, being diagnosed with a mental illness and knowing someone who is diagnosed with a mental illness were associated with a lower level of stigma. Conclusion Most of the population (91.96%) had a low to medium-low level of stigma. The variables found to affect the level of stigma were age, career, number of spoken languages, being diagnosed with a mental illness, and knowing someone who is diagnosed with a mental illness. Mental stigma has a great impact on the person, as it can prevent the patient from seeking help, lead to isolation, and suicidal ideation. Future stigma-targeted campaigns are recommended.

The Relationship of Dry Eye Disease With Depression in Saudi Arabia: A Cross-Sectional Study.

Objective Estimate the prevalence of depression among individuals with a dry eye disease (DED) in Saudi Arabia using two questionnaires: Patient Health Questionnaire (PHQ-9) and Dry Eye Questionnaire (DEQ-5), and explore potential factors implicated in the development of depression among the DED population. Methods This is a descriptive cross-sectional study of 476 patients with DED which was conducted using a PHQ-9 questionnaire to screen for depression and a DEQ-5 questionnaire to diagnose DED. The questionnaires were merged and distributed using Google Forms through various social media platforms targeting the Saudi population. After data collection, it was revised, coded and fed to statistical software IBM SPSS version 22 (SPSS, Inc. Chicago, IL). Results Depression was diagnosed among 200 participants (42%) of the cases with dry eyes. From which 5.7% had mild depression, 13.9% had moderate depression, 12.6% had moderately severe depression, and 9.9% had severe depression. A female predominance was noticed; 44.7% of the females with dry eyes had depression compared to 32.4% of males with recorded statistical significance (P=0.023). Depression was detected among 55% of those who are less than 20 years old in comparison to 27% of those who are 30 years or older (P=0.001). Laser-assisted in-situ keratomileusis (LASIK), prolonged electronic device usage and contact lens wear are reported as risk factors associated with an increase in dry eye symptoms. However, there is no statistically significant relationship between contact lens wear and depression among dry eye disease patients. Conclusion Suffering from DED is a possible risk factor for developing depression as DED is associated with depression of higher degrees of severity. Depression among DED patients is found to be significantly more prevalent among females and the young adult population rather than older adults.

Depression Among Keratoconus Patients in Saudi Arabia.

Background Depression is a highly prevalent disorder globally and locally in Saudi Arabia. Individuals with chronic conditions are more liable to develop depression. Keratoconus is a chronic progressive corneal disorder that markedly affects the vision and quality of life, making its sufferers liable to developing depression. Methods This is a descriptive cross-sectional study that was conducted using 9-item Patient Health Questionnaire (PHQ-9) to screen for depression among adults aged between 18 and 60 years old only. The participants in this study are patients who have been previously diagnosed with keratoconus by their ophthalmologists. The structured questionnaire was distributed using Google Forms through various social media platforms. After extracting the data, it was revised, coded and then analyzed using the Statistical Packages for Social Sciences (SPSS), version 21 (IBM Corp., Armonk, NY). Results A total of 330 keratoconus patients living in Saudi Arabia were recruited in this study. The modal age group was 31-40 years old (44.5%), and the male to female ratio was 3:2. The most frequently reported concurrent eye diseases of the patients were astigmatism (48.5%) and myopia (36.7%). The prevalence of depression among patients with keratoconus was 40.6% (n = 134). The use of corrective contact lens (includes both: hybrid and rigid lens) in both eyes contributed to a significantly higher depression rate among its wearers compared to users in one eye and non-users (p<0.001). Conclusion Depression is highly prevalent among keratoconus patients. This is especially true among corrective contact lens wearers of both eyes. Keratoconus is associated with depression regardless of disease severity and socio-demographic characteristics.

Tricuspid valve-in-valve jailing right ventricular lead is not free of risk.

Transcatheter tricuspid valve in valve (TViV) is increasingly performed on patients with degenerated bioprosthetic valves and elevated surgical risk. Jailing a right ventricular (RV) pacer lead at the time of TViV implantation has been achieved without causing lead dysfunction; however, device-related complications that require lead extraction raise the need for better periprocedural strategies for TViV, in pacer-dependent patients. We describe a case of device pocket infection with incomplete lead extraction, due to a jailed RV lead at the time of TViV.

Arterial Blood Pressure at Liver Transplant Evaluation Predicts Renal Histology in Candidates With Renal Dysfunction.

Renal dysfunction is common in liver transplantation (LT) candidates, but differentiating between reversible and irreversible renal injury can be difficult. Kidney biopsy might be helpful in differentiating reversible from irreversible renal injury, but it is associated with significant complications. We aimed to identify pre-LT predictors of potentially reversible renal injury using histological information obtained on pre-LT renal biopsy. Data on 128 LT candidates who underwent pre-LT kidney biopsy were retrospectively collected and correlated with renal histological findings. Indications for kidney biopsy were iothalamate glomerular filtration rate (iGFR) ≤40 mL/minute, proteinuria >500 mg/day, and/or hematuria. According to the biopsy diagnosis, patients were grouped into the following categories: normal (n = 13); acute tubular necrosis (ATN; n = 25); membranoproliferative glomerulonephritis (n = 19); minimal histological changes (n = 24); and advanced interstitial fibrosis (IF) and glomerulosclerosis (GS) (n = 47). Compared with patients having advanced IF/GS, patients with normal biopsies and those with ATN had lower systolic blood pressure (SBP) and diastolic blood pressure (DBP) and higher international normalized ratio and total bilirubin levels (<0.05 for all). Both SBP and DBP directly correlated with the degree of IF and GS (R = 0.3, P ≤ 0.02 for all). SBP ≤90 mm Hg was 100% sensitive and 98% specific in correlating with normal biopsies or ATN, whereas SBP ≥140 mm Hg was 22% sensitive and 90% specific in correlating with advanced IF/GS. Model for End-Stage Liver Disease score, serum creatinine, iGFR, urinary sodium excretion, and renal size did not correlate with biopsy diagnosis or degree of IF or GS. In conclusion, SBP at the time of LT evaluation correlates with renal histology, and it should be included along with other clinical and laboratory markers in the decision-making process to list patients with renal dysfunction for LT alone versus simultaneous liver-kidney transplantation.

Acute Pancreatitis in Advanced Chronic Kidney Disease and Kidney Transplant Recipients: Results of a US Nationwide Analysis.

OBJECTIVE: To study the prevalence, etiology, and outcome of acute pancreatitis (AP) in kidney transplant and stage 5 chronic kidney disease (CKD) populations in comparison to a non-CKD cohort. PATIENTS AND METHODS: Using the Nationwide Inpatient Sample database, we identified patients with acute pancreatitis as the primary discharge diagnosis, after which propensity scores were used to create 2 cohorts of patients: 1 with CKD (n=13,425) and 1 without CKD (n=13,425). The CKD group was subsequently subdivided into dialysis-independent stage 5 CKD (n=690), dialysis-dependent stage 5 CKD (n=11,415), and kidney transplant recipients (n=1320). Patients younger than 18 years old, those who received a kidney transplant during the incident admission, and pancreas transplant recipients were excluded. RESULTS: The adjusted odds ratios (ORs) of AP were comparable between the no CKD, stage 5 CKD, and kidney transplant populations. Adjusted inpatient mortality was highest in patients with dialysis-dependent stage 5 CKD (OR, 2.72; 95% CI, 2.2-3.3; P<.01), followed by kidney transplant recipients (OR, 2.29; 95% CI, 1.12-4.51; P=.02), compared to the non-CKD group. Patients with stage 5 CKD experienced higher rates of shock and intensive care unit admission and had more prolonged and costly hospitalizations than the non-CKD group (P<.01 for all). Hypercalcemia was the most common cause of AP in both dialysis-dependent and dialysis-independent patients with stage 5 CKD, while viral and drug-induced pancreatitis were more prevalent in the transplant recipients. CONCLUSION: Despite comparable adjusted prevalence of AP among the stage 5 CKD, transplant, and non-CKD populations, mortality, morbidity, and resource utilization were higher in the patients with stage 5 CKD and transplant recipients. Hypercalcemia is the most common cause of AP in the stage 5 CKD population irrespective of dialysis requirement.

Acute Unilateral Vision Loss Due to Optic Neuropathy in a Patient with Systemic Lupus Erythematosus.

BACKGROUND Systemic lupus erythematosus (SLE) causes sight-threatening, ophthalmologic problems that are frequently challenging to manage. Optic neuropathy is a rare ophthalmological complication of SLE that can progress to total bilateral vision loss if not identified and treated rapidly. We describe a patient with SLE who presented with an acute, painless unilateral optic neuropathy who subsequently experienced partial recovery of vision when treated with high-dose intravenous corticosteroids. CASE REPORT A 44-year-old female with known SLE presented with 4 days of painless, complete, and gradual vision loss in the right eye. Initial ophthalmologic examination revealed no light perception, afferent pupil defect, 4+ optic disc swelling, and 1+ venous tortuosity of the right eye. No hemorrhage or exudates were noted. Diagnostic workup revealed a lupus flare with elevated inflammatory markers including elevated anti-nuclear antibody, anti-ds-DNA antibody, anti-Sm antibody, and anti-phospholipid IgG antibody. The diagnosis of optic neuropathy was clinically established, and the patient was treated with high-dose intravenous corticosteroids. Her vision improved, and she was transitioned to oral corticosteroids with eventual significant improvement in her vision. CONCLUSIONS Optic neuropathy is a rare and devastating ophthalmologic complication of SLE. The diagnosis can be made by linking key clinical findings on ophthalmologic examination with positive serological studies. If treated rapidly with immunosuppressive therapy, the vision loss can be reversed, and permanent blindness avoided. Although this rare complication is generally bilateral in nature, clinician must also be aware of unilateral disease and treat patients accordingly.

Abnormal Liver Enzymes.

Abnormal liver enzymes are frequently encountered in primary care offices and hospitals and may be caused by a wide variety of conditions, from mild and nonspecific to well-defined and life-threatening. Terms such as "abnormal liver chemistries" or "abnormal liver enzymes," also referred to as transaminitis, should be reserved to describe inflammatory processes characterized by elevated alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase. Although interchangeably used with abnormal liver enzymes, abnormal liver function tests specifically denote a loss of synthetic functions usually evaluated by serum albumin and prothrombin time. We discuss the entities that most commonly cause abnormal liver enzymes, specific patterns of enzyme abnormalities, diagnostic modalities, and the clinical scenarios that warrant referral to a hepatologist.

Serum Electrolyte Levels and Outcomes in Patients Hospitalized with Hepatic Encephalopathy.

INTRODUCTION AND AIMS: Serum electrolyte derangements are common in patients with decompensated cirrhosis hospitalized for hepatic encephalopathy. There are limited data describing the association between electrolyte levels and outcomes in hepatic encephalopathy. We assessed the association between initial serum electrolyte values and outcomes in patients with hepatic encephalopathy. MATERIAL AND METHODS: A total of 385 consecutive patients hospitalized with encephalopathy were included in the study. Baseline electrolyte levels (sodium, potassium, chloride, bicarbonate, calcium and phosphorus) were measured at the time of admission and assessed for association with outcomes, which included survival, admission to the intensive care unit, requirement for mechanical ventilation, and length of hospital stay. P-values ≤ 0.0083 were considered significant after adjustment for multiple testing. RESULTS: In unadjusted analysis, significant associations were identified regarding both bicarbonate and phosphorus (admission to intensive care unit), and calcium (mechanical ventilation); however these findings weakened and no longer approached statistical significance when adjusting for confounding variables. No other significant associations between serum electrolyte measurements and outcomes were observed. CONCLUSIONS: Our findings suggest that in patients hospitalized with encephalopathy, serum electrolyte measurements are not strong predictors of patient outcome.

Appropriately testing patients with intermediate risk for coronary artery disease: how well are we doing?

BACKGROUND: Cardiovascular risk assessment and stratification of stable coronary artery disease represents a pivotal component of coronary artery disease management. The introduction of risk stratification tools has advanced the detection of patients with intermediate to high risk for coronary artery events. These patients will ultimately undergo non-invasive and invasive cardiovascular testing. OBJECTIVE: To synthesise evidence illustrating risk stratification tools and non-invasive testing for patients with intermediate risk for coronary artery disease and suggest a simple method for clinicians to follow prior to ordering non-invasive cardiovascular testing. STUDY SELECTION: Literature review of PubMed and MEDLINE Central on studies and evidence highlighting the appropriate use criteria for radionuclide myocardial perfusion imaging. FINDINGS AND CONCLUSIONS: Overtestingusing myocardial perfusion imaging is well documented in several studies in the literature. Few studies highlighted the importance of the appropriate use criteria for radionuclide myocardial perfusion imaging, which can reduce unnecessary testing in patients with suspected coronary artery disease. Herein, we propose 'Simple Steps to Follow' to be considered by clinicians prior to ordering radionuclide myocardial perfusion imaging. The target audience of this article is internal and family medicine primary care physicians and other non-cardiologist physicians.

Recurrent Syncope, a Clue in Amyloid Cardiomyopathy.

Infiltrative cardiomyopathies include a variety of disorders that lead to myocardial thickening resulting in a constellation of clinical manifestations and eventually heart failure that could be the first clue to reach the diagnosis. Among the more described infiltrative diseases of the heart is amyloid cardiomyopathy. The disease usually presents with subtle, nonspecific symptoms. Herein, we illustrate a case of recurrent syncope as the initial presenting symptom for systemic amyloid with polyneuropathy and cardiomyopathy as a cause of syncope. The article illustrates the role of advanced cardiac imaging in the diagnosis of the disease with a focused literature review. We also highlight the role of early, shared decision-making between patient, family, and medical team in the management of cardiac amyloidosis.
