Abnormal circulating steroids refine risk of progression to heart failure in ischemic heart disease.

BACKGROUND: Patients with ischemic heart disease (IHD) experience a high incidence of progression to heart failure (HF) despite current therapies. We speculated that steroid hormone metabolic disorders distinct adverse phenotypes and contribute to HF. METHODS: We measured 18 steroids using liquid chromatography with tandem mass spectrometry in 2023 patients from the Registry Study of Biomarkers in Ischemic Heart Disease (BIOMS-IHD), including 1091 patients with IHD in a retrospective discovery set and 932 patients with IHD in a multicentre validation set. Our outcomes included incident HF after a median follow-up of 4 years. RESULTS: We demonstrated steroid-based signatures of inflammation, coronary microvascular dysfunction and left ventricular hypertrophy that were associated with subsequent HF events in patients with IHD. In both cohorts, patients with a high steroid-heart failure score (SHFS) (>1) exhibited a greater risk of incident HF than patients with a low SHFS (≤1). The SHFS further improved the prognostic accuracy beyond clinical variables (net reclassification improvement of 0.628 in the discovery set and 0.299 in the validation set) and demonstrated the maximal effect of steroid signatures in patients with IHD who had lower B-type natriuretic peptide levels (pinteraction = 0.038). CONCLUSIONS: A steroid-based strategy can simply and effectively identify individuals at higher HF risk who may derive benefit from more intensive follow-ups.

Abnormal plasma ceramides refine high-risk patients with worsening heart failure.

Background: Worsening heart failure (WHF) is a heterogeneous clinical syndrome with poor prognosis. More effective risk stratification tools are required to identify high-risk patients. Evidence suggest that aberrant ceramide accumulation can be affected by heart failure risk factors and as a driver of tissue damage. We hypothesized that specific ceramide lengths and ratios serve as biomarkers for risk stratification in WHF patients by reflecting pathological changes of distinct organ dysfunctions. Medthods: We measured seven plasma ceramides using liquid chromatography-mass spectrometry (LC-MS) in 1,558 patients, including 1,262 participants in retrospective discovery set and 296 WHF patients in prospective validation set in BIOMS-HF study (Registry Study of Biomarkers in Heart Failure). Univariable and multivariable logistic regression models were constructed to identify associations of ceramides with organ dysfunctions. Results: We constructed three ceramide-based scores linked independently to heart, liver, and kidney dysfunction, with ceramides and ratios included in each score specifying systemic inflammation, chronic metabolic disorder, and water-sodium retention. The combined ceramide heart failure score (CHFS) was independently associated with adverse outcomes [Hazard Ratio, 2.80 (95% CI: 1.78-4.40; P < 0.001); 2.68 995% CI: 1.12-6.46; P = 0.028)] and improved the predictive value of Acute Decompensated Heart Failure National Registry score and BNP [net reclassification index, 0.34 (95% confidence interval, CI: 0.19-0.50); 0.42 (95% CI: 0.13-0.70)] in the discovery and validation set, respectively. Lower BNP levels, but higher CHFS had the highest hazard of future adverse events in WHF patients. Conclusion: Abnormal plasma ceramides, associated with heart and peripheral organ dysfunctions, provide incremental prognostic information over the ADHERE score and brain natriuretic peptide concentration for risk stratification in WHF patients. This may facilitate the reclassification of high-risk patients in need of aggressive therapeutic interventions.

Aldosterone dysregulation predicts the risk of mortality and rehospitalization in heart failure with a preserved ejection fraction.

Serum aldosterone is associated with cardiac remodeling, which contributes to morbidity and mortality in heart failure (HF); however, the prognostic value of aldosterone in HF with a preserved ejection fraction (HFpEF) is unclear. We used liquid chromatography-tandem mass spectrometry to quantify serum aldosterone in 873 patients with HFpEF in a Registry Study of Biomarkers for HF. The retrospective study was conducted at Beijing Anzhen Hospital from May 2017 to October 2019. The primary endpoint was a composite of all-cause mortality and rehospitalization for HF. Aldosterone concentrations in patients with and without events were 124.22 pmol L-1 (interquartile range (IQR): 48.62-256.20) and 96.33 pmol L-1 (IQR: 37.33-215.76), respectively (P=0.023). Aldosterone independently predicted all-cause mortality (adjusted hazard ratio (aHR), 1.55; 95% confidence interval (95%CI), 1.06-2.27; P=0.024) and the primary endpoint (aHR, 1.43; 95%CI, 1.11-1.85; P=0.006). Patients with high aldosterone concentrations were at higher risk of concentric remodeling (adjusted odds ratio (aOR), 1.45; 95% CI, 1.03-2.04; P=0.034). Patients with high aldosterone and B-type natriuretic peptide concentrations were at a higher risk of the primary endpoint (hazard ratio (HR), 1.85; 95%CI, 1.29-2.66; P=0.001). We conclude that elevated aldosterone is associated with a risk of rehospitalization with HF and all-cause mortality in patients with HFpEF.

Magnetic Resonance Imaging Features of Pediatric Coxsackievirus Encephalitis.

Coxsackievirus, a common pathogen causing pediatric infection, typically causes a mild, nonspecific illness with low-grade fever, but can cause severe illness on rare occasions. Encephalitis is an uncommon but important complication of coxsackievirus infection. The magnetic resonance imaging (MRI) findings of coxsackievirus B3 (CVB3) encephalitis have not been reported in the literature, and there are few descriptions of MRI findings of encephalitis induced by coxsackieviruses of other serotypes. We report the MRI findings of CVB3 encephalitis in a two-year-old girl, review the MRI findings in previously reported cases of pediatric coxsackievirus encephalitis, and present the MRI characteristics of coxsackievirus encephalitis.

Artery of percheron occlusion in an elderly male: a case report.

Acute bilateral paramedian thalamic and mesencephalic infarcts are uncommon. Occlusion of the artery of Percheron (AOP) is presumed to cause this specific stroke syndrome. However, occlusion of the AOP is rare and early diagnosis is challenging. Here we described a 70-year-old male patient who presented with acute disturbance of consciousness due to acute bilateral paramedian thalamo-mesencephalic infarction secondary to AOP occlusion. Anticoagulant therapy was administered, and his consciousness gradually improved.

Isolated thunderclap headache during sex: Orgasmic headache or reversible cerebral vasoconstriction syndrome?

Orgasmic headache (OH) is an "explosive" headache that occurs at orgasm. Historically, it was considered benign with no treatment needed. Reversible cerebral vasoconstriction syndrome (RCVS) refers to a group of disorders characterized by recurrent thunderclap headache (TCH) and multifocal vasoconstriction. Patients who have RCVS often recover completely, but some may have persistent neurological deficits. We report a 34-year-old woman who presented with isolated and recurrent TCH at orgasm, which fulfilled the diagnosis of OH. However, she was post-partum and had recent exposure to ecstasy, making her symptoms highly suggestive of RCVS. Brain magnetic resonance angiography showed segmental vasoconstriction. We concluded that she could be considered to have either OH or RCVS. This patient suggests the theory that OH could be a presentation of RCVS. Given that RCVS is potentially treatable, early recognition by clinicians is vital in order to prevent devastating complications.

Unusual presentation of metastatic hepatocellular carcinoma in the nasal septum: a case report and review of the literature.

Hepatocellular carcinoma with sinonasal metastasis is extremely rare. We report a case of a 49-year-old man who had a history of synchronous hepatocellular carcinoma and verrucous carcinoma of tongue. A painless and non-bleeding mass was found in the left nasal septum 16 months after hepatocellular carcinoma was diagnosed. On computed tomography, the mass was enhanced with contrast. It was resected and proved to be metastatic hepatocellular carcinoma. The patient was treated with radiotherapy to the nasal area and then with chemotherapy. He was still alive, 15 months after the appearance of the nasal metastasis.
