Cancer as an Individual Risk Factor for Heart Failure: A Review of Literature.

The intricate relationship between cancer and cardiovascular diseases (CVD), notably heart failure (HF), is gaining attention in the medical field. This literature review explores the intricate interplay between cancer and CVD, particularly HF, emphasizing their significant impact on global mortality and comorbidity. While preventive measures have contributed to reducing their incidence, challenges persist in predicting and managing cancer-related complications. This review article delves into various risk factors associated with both cancer and HF, including lifestyle factors, genetic predispositions, and immune system dysregulation. It highlights emerging evidence suggesting a direct interaction between cancer and HF, with studies indicating an elevated risk of mortality from cancer in patients with HF and vice versa. Pathological mechanisms such as inflammation, oxidative stress, and tissue hypoxia are implicated in cancer-induced cardiac dysfunction, underscoring the need for comprehensive clinical investigations and ethical considerations in patient care. The review also discusses the potential role of biomarkers in risk assessment, early detection of cardiotoxicity, and understanding common pathophysiological links between cancer and HF, paving the way for multifaceted preventive and therapeutic approaches.

Multi-year population-based analysis of Asian patients with acute decompensated heart failure and advanced chronic kidney disease.

BACKGROUND: Data on disparities in outcomes and risk factors in Asian patients with advanced chronic kidney disease admitted for heart failure are scare. METHODS: This was a retrospective cohort study that utilized data from the National Inpatient Sample between January 2016 and December 2019. Patients who had a primary diagnosis of acute decompensated heart failure and a concomitant diagnosis of advanced CKD were included. The primary outcome of interest was in-hospital mortality. Secondary outcomes include hospital cost, length of stay, and other clinical outcomes. Weighted multivariable logistic regression was used to adjust for comorbidities. RESULTS: There were 251,578 cases of ADHF with advanced CKD, out of which 2.6 % were from individuals of Asian ethnicity. Asian patients exhibited a higher burden of comorbidities in comparison to other UREM patients, but a lower burden than White patients. Regardless of differences in comorbidity burden, Asian patients exhibited a higher likelihood of experiencing severe consequences. After adjusting for comorbidies, White (OR:1.11; 95 % CI 1.03-1.20;0.009) patients had higher odds of mortality than Asian patients. However, Blacks (OR: 0.58; 95 % CI 0.53 to 0.63; p < 0.001) and Hispanics (OR: 0.69; 95 % CI 0.62 to 0.78; p < 0.001) had lower odds of mortality. CONCLUSION: This first population-based studies shows that Asian patients with advanced CKD admitted for ADHF have greater comorbidity burden and poorer outcomes Black and Hispanic patients. This data underscores the importance of comprehensive approaches in phenotyping, and ethnic specific interventions.

Chunky Mitral Annular Calcification: Caseoma or a Tumor?

Mitral annular calcification (MAC) is relatively common in clinical practice. Females are more often affected than males. Patients with end-stage renal disease have MAC relatively more commonly than the general population. Patients with MAC often develop conduction system disturbances, including advanced atrioventricular blocks. They are also more likely to develop various arrhythmias, including atrial fibrillation. Caseous mitral annulus calcification is a variant of MAC that often looks like a cardiac tumor on an echocardiogram and needs to be differentiated.

Unlocking the Hidden Pathway: A Rare Encounter With Right Coronary Artery Fistula to Coronary Sinus and Right Ventricle.

Coronary artery fistulas (CAFs) are rare vascular anomalies characterized by abnormal connections between coronary arteries and cardiac chambers or adjacent structures. Advances in cardiac interventions have led to an increasing recognition of acquired CAFs, which are typically congenital. We present a case of a 62-year-old male with a complex medical history, including hypertension, atrial fibrillation, and heart failure, who presented with exertional chest pain and palpitations. Diagnostic evaluation revealed a significant CAF originating from the right coronary artery (RCA) and terminating into the coronary sinus and right ventricle. Despite the absence of significant coronary artery occlusions, the fistula was deemed clinically significant due to its potential to cause myocardial ischemia. Management involved guideline-directed medical therapy and lifestyle modifications. This case underscores the importance of early recognition and appropriate management of CAFs to optimize patient outcomes. Further research is needed to better understand the natural history and optimal management strategies of CAFs.

Gender Disparity in Leading Authorship of Critical Care Clinical Trials: A Systematic Review and Meta-Analysis.

In critical care medicine, research trials serve as crucial avenues for disseminating knowledge, influencing clinical practices, and fostering innovation. Notably, a significant gender imbalance exists within this field, potentially mirrored in the authorship of critical care research. This study aimed to investigate an exploration to ascertain the presence and extent of female representation in first and senior authorship roles within critical care literature. To this end, a systematic search was conducted across PubMed, Google Scholar, and Web of Science databases for original articles published up to February 2024, coupled with a methodological quality assessment via the Newcastle-Ottawa Scale (NOS) and statistical analyses through Review Manager software (RevMan, version 5.4.1, The Cochrane Collaboration, 2020). The study's findings, distilled from seven studies included in the final analysis, reveal a pronounced gender disparity. Specifically, in critical care literature examining mixed populations, female first authors were significantly less common than their male counterparts, with an odds ratio (OR) of 4.25 (95% confidence interval (CI): 3.18-5.68; p < 0.00001). Conversely, pediatric critical care studies did not show a significant difference in gender distribution among first authors (OR: 1.37; 95% CI: 0.31-6.10; p = 0.68). The investigation also highlighted a stark underrepresentation of female senior authors in critical care research across both mixed (OR: 11.67; 95% CI: 7.76-17.56; p < 0.00001) and pediatric populations (OR: 5.41; 95% CI: 1.88-15.56; p = 0.002). These findings underscore the persistent underrepresentation of women in critical care literature authorship and their slow progression into leadership roles, as evidenced by the disproportionately low number of female senior authors.

Advancing Healthcare Equity in Nephrology: Addressing Racial and Ethnic Disparities in Research Trials and Treatment Strategies.

Within the healthcare sector, especially in the field of nephrology, the matter of gender and racial inequalities continues to be a critical concern that requires immediate focus. Women, particularly those of underrepresented racial groups, face significant challenges due to a lack of representation in research studies, leading to a deficit in knowledge about how kidney diseases affect them differently. These challenges are exacerbated by systemic biases in the healthcare system, which manifest in both gender and racial dimensions, hindering access to and the quality of care for kidney diseases. Addressing these complex disparities requires a recalibration of risk stratification models to include both gender- and race-specific factors and a transformation of healthcare policies to facilitate a more inclusive and sensitive approach. Essential to this transformation is the empowerment of women of all races to actively participate in their healthcare decisions and the strengthening of support systems to help them navigate the complexities of the healthcare environment. Furthermore, education programs must be designed to be culturally competent and address the unique needs and concerns of women across different racial backgrounds. Promoting a collaborative patient-provider relationship is crucial in fostering an environment where equity, dignity, and respect are at the forefront. The path to equitable nephrology care lies in a concerted, collective action from researchers, healthcare providers, policymakers, and patients, ensuring that every individual receives the highest standard of care, irrespective of gender or race.

The Silent Victims: How the Israel-Palestine War Impacts the Management of Chronic Kidney Disease and End-Stage Renal Disease Patients.

This article discusses the multifaceted impact of wars and armed conflicts on healthcare systems, with a focus on the Israel-Palestine war and its consequences for individuals with chronic kidney disease (CKD) and end-stage renal disease (ESRD). The war has severely disrupted healthcare infrastructure, leading to damage or destruction of hospitals and clinics, shortages in medical supplies and staff, and interruptions in the delivery of essential services. This disruption poses significant challenges for the management of chronic conditions such as CKD and ESRD, where patients rely on regular and specialized care. The article highlights the logistical challenges and health risks faced by these patients, including the interruption of dialysis treatment, shortages of medications, and the impact of displacement on continuity of care. It also addresses the psychological toll on patients, emphasizing the increased stress, anxiety, and depression that can exacerbate their condition. The need for international aid and humanitarian efforts to support CKD and ESRD patients in conflict zones is underscored, along with the importance of addressing the root causes of the conflict to ensure the well-being of vulnerable populations.

A Systematic Review of Gender Disparity in the Authorship of Clinical Trials and Clinical Practice Guidelines in Various Medicine Subspecialties.

Authorship in clinical trials and clinical practice guidelines is considered prestigious and is associated with broader peer recognition. This systematic review investigated female representation among studies reporting authorship trends in clinical trials or clinical practice guidelines in different medicine subspecialties. Our search strategy yielded 836 articles, of which 30 met the inclusion criteria. Our findings indicate that females are severely underrepresented in authorship of clinical trials and clinical practice guidelines. Although the proportions of females may have improved in the past decade, the gains are marginal. Notably, studies in this domain predominantly focus on first/last authorship positions, and whether females are underrepresented in other positions as collaborative partners is currently unknown. Also, authorship trends in clinical trials or clinical practice guidelines of most medicine subspecialties besides cardiovascular medicine remain under-researched. Hence, standardizing the methodology for studying gender disparity in research output for comparative analysis between different subspecialties is as urgent as addressing the gender disparity in authorship.

The current state of training in pain medicine fellowships: An Association of Pain Program Directors (APPD) survey of program directors.

INTRODUCTION: The Accreditation Council for Graduate Medical Education (ACGME) approved the first pain medicine fellowship programs over three decades ago, designed around a pharmacological philosophy. Following that, there has been a rise in the transition of pain medicine education toward a multidisciplinary interventional model based on a tremendous surge of contemporaneous literature in these areas. This trend has created variability in clinical experience and education amongst accredited pain medicine programs with minimal literature evaluating the differences and commonalities in education and experience of different pain medicine fellowships through Program Director (PD) experiences. This study aims to gather insight from pain medicine fellowship program directors across the country to assess clinical and interventional training, providing valuable perspectives on the future of pain medicine education. METHODS: This study involved 56 PDs of ACGME-accredited pain fellowship programs in the United States. The recruitment process included three phases: advanced notification, invitation, and follow-up to maximize response rate. Participants completed a standard online questionnaire, covering various topics such as subcategory fields, online platforms for supplemental education, clinical experience, postgraduate practice success, and training adequacy. RESULTS: Surveys were completed by 39/56 (69%) standing members of the Association of Pain Program Directors (APPD). All PDs allowed fellows to participate in industry-related and professional society-related procedural workshops, with 59% encouraging these workshops. PDs emphasized the importance of integrity, professionalism, and diligence for long-term success. Fifty-four percent of PDs expressed the need for extension of fellowship training to avoid supplemental education by industry or pain/spine societies. CONCLUSION: This study highlights the challenge of providing adequate training in all Pain Medicine subtopics within a 12-month pain medicine fellowship. PDs suggest the need for additional training for fellows and discuss the importance of curriculum standardization.

PET/CT and SPECT/CT Imaging of HER2-Positive Breast Cancer.

HER2 (Human Epidermal Growth Factor Receptor 2)-positive breast cancer is characterized by amplification of the HER2 gene and is associated with more aggressive tumor growth, increased risk of metastasis, and poorer prognosis when compared to other subtypes of breast cancer. HER2 expression is therefore a critical tumor feature that can be used to diagnose and treat breast cancer. Moving forward, advances in HER2 in vivo imaging, involving the use of techniques such as positron emission tomography (PET) and single-photon emission computed tomography (SPECT), may allow for a greater role for HER2 status in guiding the management of breast cancer patients. This will apply both to patients who are HER2-positive and those who have limited-to-minimal immunohistochemical HER2 expression (HER2-low), with imaging ultimately helping clinicians determine the size and location of tumors. Additionally, PET and SPECT could help evaluate effectiveness of HER2-targeted therapies, such as trastuzumab or pertuzumab for HER2-positive cancers, and specially modified antibody drug conjugates (ADC), such as trastuzumab-deruxtecan, for HER2-low variants. This review will explore the current and future role of HER2 imaging in personalizing the care of patients diagnosed with breast cancer.

Role of peripheral nerve stimulation in treating chronic neuropathic pain: an international focused survey of pain medicine experts.

Interventional pain management (IPM) options for refractory neuropathic pain (NP) have recently increased with availability of peripheral nerve stimulation (PNS) equipment and expertise. Given a lack of high-quality evidence and guidelines on this topic, we sought to understand the perception of physicians with expertise in treating NP regarding IPM and the role of PNS. We emailed a survey in March 2022 to international NP experts including pain medicine physicians, researchers, and leaders of 11 professional pain societies. No representatives from vendors of PNS systems were included in the design of the survey nor as respondents. Among 24 respondents (67% of those contacted), the distal common peroneal, tibial, and sural nerves were most frequently targeted (60%) with PNS. Persistent postsurgical pain of more than 3 months was the most common indication for PNS (84%). The aggregate NP treatment algorithm in order of median rank was non-opioid medications as first line, IPM including epidural/perineural steroid injections tied with transcutaneous electrical nerve stimulation as second line, pulsed radiofrequency (RF) tied with RF ablation/denervation as third line, temporary then permanent PNS as fourth line, followed by spinal cord stimulation, opioids, cryoablation, botulinum, peripheral nerve field stimulation, intrathecal targeted drug delivery, and others. Before offering PNS, 12 respondents (50%) indicated their preference for trialing non-neuromodulation treatments for 1-3 months. Twenty-two respondents (92%) agreed PNS should be offered early in the treatment of neuropathic pain. The most common barriers to PNS use were cost, lack of high-quality evidence in support of its use, lack of exposure to PNS in training programs, and lack of familiarity with the use of ultrasound guidance. PNS appears to have an increasing role in the treatment of NP but more research is needed on the outcomes of PNS to elucidate its role.

A Case of JAK2V617F-Negative Myeloproliferative Neoplasm in a Young Female Presenting With Extreme Thrombocytosis.

Thrombocytosis is a commonly observed condition in clinical practice and typically results from various pathophysiological factors, such as iron deficiency, blood loss, infection, medications, rheumatologic conditions, malignancy, asplenia, post-splenectomy, or familial factors. However, extreme thrombocytosis, defined as a platelet count > 10,000 K/UL (equal or greater than a million), is a rare occurrence. In this report, we present a compelling case of severe thrombocytosis attributed to underlying chronic myelogenous leukemia (CML), further complicated by coexisting iron deficiency. It is essential to emphasize that not all instances of extreme thrombocytosis are indicative of essential thrombocythemia. Hence, maintaining a high level of suspicion for non-ET myeloproliferative neoplasms (MPNs) such as CML, as well as other underlying conditions like iron deficiency anemia, is crucial for accurate diagnosis and timely management.

Acute COVID-19-Associated Cardiac Arrhythmia: A Case Series and Literature Review.

Coronavirus disease 2019 (COVID-19) is a highly contagious infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We report two cases of COVID-19-associated atrial fibrillation (AF) in two elderly females and a case of atrial flutter (AFlutter) in a middle-aged male patient. We believe this case series will contribute to the literature on new-onset AF and AFlutter in patients with acute COVID-19 infection. This case series illustrates various case scenarios of patients developing cardiac arrhythmia with acute COVID-19 infection without any prior history or other explicable cause of AF/AFlutter. The exact mechanism behind COVID-19 infection leading to AF or AFlutter is still unknown. Of the three patients reported, two converted to sinus rhythm following medical management, and one did not convert to sinus rhythm despite medical treatment.

Non Ischemic Cardiomyopathy in a 54-Year-Old Khat Consuming Yemeni Male Presenting with Worsening Exertional Dyspnea, T Wave Inversions in V5-V6 and Normal Coronary Artery Angiography.

BACKGROUND Khat (Catha edulis) is a plant cultivated in Ethiopia, East African, and the Arabian Peninsula. Long-term khat consumption has been associated with increased rates of periodontal diseases, esophagitis, psychosis, and cardiovascular issues such as cerebrovascular accidents, myocardial ischemia, and ischemic cardiomyopathy (CM). We report a case of khat-induced non-ischemic CM in a patient with no other known cardiovascular risk factors and highlight a cardiovascular effect of chronic khat consumption. CASE REPORT A 54-year-old Yemeni man with no known medical history but a chronic khat chewer presented with worsening exertional dyspnea for 6 months and associated pedal edema. Laboratory studies were remarkable for elevated B-type natriuretic peptide (BNP). Electrocardiogram (EKG) revealed normal sinus rhythm with non-specific T wave inversions (TWI) in V5-V6. A computed tomography (CT) scan of the chest showed bilateral pleural effusions with interlobular septal thickening. Transthoracic echocardiogram (TTE) showed a left ventricular ejection fraction (LVEF) of 16-20% and global CM. Coronary angiography revealed normal coronaries. CONCLUSIONS Chronic khat consumption is being recognized as a dangerous habit with serious health consequences and its association with ischemic CM is well documented. The findings of ischemic cardiac changes of acute coronary syndrome in a patient with normal coronary arteries raises the possibility that khat toxicity was associated with coronary artery spasm due to its amphetamine-like stimulatory effects. Although further research is required to substantiate this relationship, it is imperative that khat consumption be considered a risk factor when assessing for CM.

A Young Heart With Coronary Dissection.

Chest pain is one of the common complaints encountered in clinical practice. Multiple diseases present as chest pain and often the etiology can be challenging to diagnose. Among the cardiac causes, coronary artery dissection is one of the life-threatening conditions and is often misdiagnosed as an acute coronary syndrome because of its similar presentation. In this case report, we will share a case of coronary artery dissection, which was initially managed as a non-ST-elevation myocardial infarction. We will share the modalities used to diagnose spontaneous coronary artery dissection and how the management differs between acute coronary syndrome and spontaneous coronary artery dissection.

COVID-19 mRNA Vaccine-Associated Myocarditis.

Coronavirus disease 2019 (COVID-19) has been reported to cause cardiovascular complications including myocarditis, pericardial effusion, pericarditis, and arrhythmias. With the introduction of the vaccine, there have been reports of myocarditis possibly associated with the mRNA COVID-19 vaccine. We report a case of cardiac involvement following the second dose of Pfizer-BioNTech COVID-19 vaccine in a young male. A healthy 24-year-old male presented to the emergency department with complaints of non-radiating mid-sternal chest pain and pressure. He noticed his symptoms started six hours after he received the second dose of Pfizer COVID vaccine. Laboratory tests revealed elevated cardiac troponin I-CtNI levels. Computed tomography angiography of the chest did not show evidence of pulmonary embolism. Given his presentation of acute chest pain associated with elevated troponin levels, a coronary angiogram was performed which revealed normal coronary arteries. He was subsequently treated for acute peri-myocarditis with colchicine, non-steroidal anti-inflammatory drugs (NSAIDs), and beta-blockers for tachycardia and the prevention of arrhythmia. Although rare, clinicians should be aware of the risk for myocarditis and pericarditis, which should be considered in individuals presenting with chest pain within a week after vaccination, especially in the younger population. Although the long-term risk in these patients is uncertain, early diagnosis and treatment are key to minimizing complications.

Mitral stenosis in a teenager after rheumatic mitral valve regurgitation valve repair: A case report.

Introduction: Mitral stenosis (MS) is a widely known complication of mitral valve repair for non-rheumatic mitral regurgitation (MR). Few reports are available on the occurrence of MS after mitral valve repair for rheumatic MR in young populations. Case summary: A 14-year-old girl presented with orthopnea, abdominal distension, and bilateral lower-limb edema. She was cachectic, with a high-pitched holosystolic murmur best heard at the cardiac apex, bilateral basal crackles, tender hepatomegaly, pitting pedal edema, and jugular venous distension. Antistreptolysin O (ASO) titer was elevated. Transthoracic echocardiography (TTE) revealed the loss of central coaptation of the mitral valve with leaflet restriction and MR, annular dilatation of the tricuspid valve, and tricuspid regurgitation (TR). She had AHA/ACC stage D mitral and TR s. Tricuspid annuloplasty and mitral valve repair for rheumatic MR were performed using Carpentier Edwards numbers 30 and 34, respectively. Following surgery, the weight and body mass index (BMI) rapidly normalized. The patient also developed progressive MS. Discussion: Previous studies in adults have described the etiopathogenesis of MS after non-rheumatic mitral valve repair. There is a paucity of reports describing the development of MS over the span of months after rheumatic MR valve repair in early pubescent children. Conclusion: Growth spurts during puberty can potentially affect MR repair, as the mitral valve prosthesis based on the preoperative Body Surface Area (BSA) is outgrown. There is a need for research on planning, prognostication, and development of an optimal, individualized, and adaptable approach to MR intervention in early pubescence.

Nivolumab-Induced Crescentic Immunoglobulin A Nephropathy With Henoch-Schonlein Purpura Features in a Patient Diagnosed With Hepatocellular Carcinoma.

A 60-year-old Polish male with a history of alcoholism, liver cirrhosis, and hepatocellular carcinoma presented via a referral from his primary medical doctor to the emergency room with respiratory distress, acute kidney injury (AKI), and a purpuric rash on both lower extremities. He had received a total of 16 doses of Nivolumab for hepatocellular carcinoma. He had a baseline serum creatinine of 1.5 and Nivolumab was skipped a month prior to presentation because of a rise in creatinine and the onset of the rash. Labs showed a blood urea nitrogen (BUN) level of 52 mg/dl and creatinine of 3.2 mg/dl. Urinalysis revealed 300 mg proteinuria and 25-50 red blood cells on a high-power field. He was subsequently placed on steroids for vasculitis manifesting as glomerulonephritis and dermatitis. Biopsy specimens of the kidney and skin were taken and showed focally crescentic diffuse proliferative glomerulonephritis with low-grade A IgA deposits and acute tubular necrosis. The skin biopsy revealed leukocytoclastic vasculitis. We hereby describe a case of focally crescentic diffuse proliferative glomerulonephritis with low-grade A IgA deposits and acute tubular necrosis in an individual with Nivolumab-treated hepatocellular carcinoma.

Recognizing Kounis Syndrome: A Report of Type 2 Kounis Syndrome and a Brief Review of Management.

Kounis syndrome is an underdiagnosed medical condition and represents acute coronary syndrome in the setting of allergic reaction. With the increasing prevalence of allergic reactions, more cases of Kounis syndrome are being reported in the literature. Recognizing patients with acute coronary syndrome during an episode of anaphylaxis may be difficult due to symptom overlap; hence, a high index of suspicion must be maintained. This is vital as the management of Kounis syndrome requires meticulous use of medications as some pharmacological agents beneficial to acute coronary syndrome may be detrimental for the ongoing anaphylaxis and vice versa. We report a case of type 2 variant of Kounis syndrome following severe anaphylaxis to nuts to highlight the need for clinicians to suspect Kounis syndrome when managing patients with anaphylaxis and chest symptoms.
