Background: Immune checkpoint inhibitors (ICIs) have been successfully used in the previous decade for the treatment of a variety of malignancies. Adverse events (AEs) can cause many symptoms, most notably cardiac. We analyzed the frequency of these adverse events, comparing pembrolizumab and other ICIs. Methods: Using the Food and Drug Administration (FDA) adverse event reporting database (FAERS), we searched for all adverse events of interest reported for every ICI included in this study. After obtaining the data, we conducted a disproportionality analysis using the reporting odds ratio (ROR) and the information component (IC). Results: A total of 6719 ICI-related cardiac adverse events of interest were reported in the database. Serious outcomes were reported in 100% of the cases, with 34.3% of the cases ending fatally. Compared with all other medications in the database, pembrolizumab use was more frequently associated with myocarditis, pericardial disease, heart failure, and atrial fibrillation. No difference was found in cardiotoxicity between different ICIs. Conclusions: Although infrequent, cardiac AEs in pembrolizumab use are associated with serious outcomes and high mortality. Prospective studies are needed to further research the connection between ICI use and cardiotoxicity.

Objective: This pilot study aimed to determine the correlation of metabolic syndrome (MetS), its components, and increased LDL (low-density lipoprotein) and total cholesterol levels with osteoarthritis (OA). In addition, our goal was to establish the association between MetS and the degree of handicap measured by the Lequesne index of functionality and severity of knee osteoarthritis. Materials and methods: The pilot study included 25 subjects with knee OA and 19 subjects without knee OA. All subjects were menopausal or premenopausal women. MetS was diagnosed according to the National Cholesterol Education Program, Adult Treatment Panel III. OA was diagnosed if Kellgren-Lawrence ≥ 2. Results: MetS was detected in 80% of subjects with OA. In the non-OA group, MetS was detected in 26% of subjects. The difference in MetS prevalence between the two groups was significant (p=0.000). The presence of each MetS component was significant in the OA group, except for central obesity, which presence was marginally significant (p=0.054). Prevalence of increased total (p=0.019) and LDL cholesterol (p=0.000) was also significant in the OA group. A significant difference between OA and the non-OA group was detected in the prevalence of all five MetS components (p=0.016). In the OA group, the Lequesne index of functionality and severity of knee osteoarthritis was not significantly altered between subjects with and without MetS. Conclusion: Metabolic syndrome, its components, increased LDL, and total cholesterol are correlated with osteoarthritis in premenopausal and menopausal women. MetS is not correlated with the degree of handicap in the knee joint measured by the Lequesne index.

Fungal pericarditis is a rare disease but its incidence has risen in parallel with the global increase in invasive fungal infections. This systematic review analyzes data from previously reported cases of fungal pericarditis to provide an improved understanding of the etiology, clinical presentation, management, and outcomes of this rare disease. We reviewed Medline and Scopus databases from 1 January 1990 to 29 January 2024 for case reports that documented the isolation of a fungal pathogen from pericardial fluid or tissue. Of the 2330 articles screened, 101 cases met the inclusion criteria. Patients with fungal pericarditis and the involvement of at least one other organ—usually the lungs, brain, or kidney—had worse outcomes than patients with isolated pericardial disease. Immunosuppression was reported in 50% of cases and was associated with worse outcomes in adults. Patients who presented with chest pain, received adequate empiric antifungal therapy, and underwent pericardiocentesis and pericardiectomy had improved survival. The most common isolated pathogens were Candida spp., followed by Aspergillus spp. and Mucor spp., with the latter two linked to worse outcomes. Only 35% of patients received empiric antifungal medications before the causative pathogen was identified, and mortality was associated with a delay in appropriate therapy. Immunosuppression, disseminated disease, and presence of shock/multiorgan failure were additional risk factors associated with death. Fungal pericarditis carries a mortality rate of up to 50%, with nearly half of patients being immunocompromised. Clinicians frequently do not consider fungal pericarditis in the differential diagnoses, which leads to delays in treatment and poorer outcomes. Further prospective multicenter studies are urgently needed to better understand the epidemiology, improve diagnostic testing and management, and decrease unacceptably high mortality in patients with fungal pericarditis.

(1) Background: Cardiomyopathy in celiac disease or celiac cardiomyopathy (CCM) is a serious and potentially life-threatening disease that can occur in both adults and children. However, data supporting the causal relationship between celiac disease (CD) and cardiomyopathy (CMP) are still inconsistent. The aim of this study was to review and synthesize data from the literature on this topic and potentially reveal a more evidence-based causal relationship. (2) Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to search Medline, Embase, and Scopus databases from database inception until September 2023. A total of 1187 original articles were identified. (3) Results: We identified 28 CCM patients (19 adult and 9 pediatric) with a mean age of 27.4 ± 18.01 years. Adult patients with CCM were predominantly male (84.2%) while pediatric patients were predominantly female (75%). The most common comorbidities associated with CCM were anemia (75%) and pulmonary hemosiderosis (20%). In 35% of patients, CCM occurred before the diagnosis of CD, while in 48% of patients, CCM and CD were diagnosed at the same time. Diagnosis of CD preceded diagnosis of CCM in only 18% of patients. Diagnosis of CCM is often delayed with an average, from the onset of symptoms to diagnosis, of 16 months. All patients were treated with a gluten-free diet in addition to guideline-directed medical therapy. At 11-month follow-up, cardiovascular improvement was seen in 60.7% of patients. Pediatric mortality was 33.3%, while adult mortality was 5.3%. (4) Conclusions: Clinicians should be aware of the possible association between CD and CMP, and we recommend CD work-up in all patients with CMP who have concomitant anemia. While we identified only 28 cases in the literature, many cases might go unreported due to a lack of awareness regarding CCM. A high degree of clinical suspicion and a prompt diagnosis of CCM are essential to minimizing the risks of morbidity and mortality, as the combination of a gluten-free diet and guideline-directed medical therapy can improve clinical outcomes.

Rheumatic heart disease (RHD) is a major challenge to global health, primarily in low- and middle-income countries. Even though RHD is rare in high-income countries, it still poses a health challenge, yet there is a lack of data on its impact within the highest-income regions. The purpose of this study was to compare the epidemiology of RHD in the United States of America (USA) and the European Union (EU). Data on RHD burden were collected using the Global Disease Burden Study 2021 using the Global Health Data Exchange query tool. Age-standardized rates of incidence (ASIR), prevalence (ASPR), death (ASDR), disability-adjusted life years (ASDALY), years lived with disability (ASYLD), and years of life lost (ASYLL) were collected. Estimated annual percentage change (EAPC) was calculated. In USA in 2021, the ASPR was 123.4/100,000 with a decreasing annual trend of 0.32% since 1993. Between 2021 and 1993, the ASIR decreased from 10.6 to 10.0/100,000 cases. In the EU in 2021, the ASPR was 49.7/100,000 cases, with an annual decreasing trend of 1.6% between 2021 and 1993. Between 2021 and 1993, the ASIR decreased from 7.43 to 4.6/100,000 cases. The changing prevalence and incidence in the US was primarily driven by Florida, Nevada, and Tennessee. There has been a reversal in the burden of RHD since 2007 in the USA. In both regions, there was a significant gender disparity with female predominance. The EU reported higher age-standardized disability-adjusted life years and age-standardized years of life losts than the USA. The varied trends underscore the complexity of RHD epidemiology and the need for region-specific strategies to address this persistent health challenge.

An 82-year-old man who had undergone Watchman FLX (Boston Scientific) device implantation presented with dyspnea. Multimodality evaluation demonstrated a small fistula from the proximal circumflex artery to the left atrial appendage. Anatomically, the left circumflex artery is close to the atrial appendage; therefore, it is plausible that fistula formation could be a late complication of implantation of the device.
