Risk Prediction in Male Adolescents With Congenital Long QT Syndrome: Implications for Sex-Specific Risk Stratification in Potassium Channel-Mediated Long QT Syndrome.

Background: Sex-specific risk management may improve outcomes in congenital long QT syndrome (LQTS). We recently developed a prediction score for cardiac events (CEs) and life-threatening events (LTEs) in postadolescent women with LQTS. In the present study, we aimed to develop personalized risk estimates for the burden of CEs and LTEs in male adolescents with potassium channel-mediated LQTS.

Use of oral contraceptives in women with congenital long QT syndrome.

Background: Use of oral contraceptives (OCs) may modulate the clinical course of women with congenital long QT syndrome (LQTS). The safety of OC use by sex hormone content has not been assessed in women with LQTS.

Objective: We aimed to evaluate the association of OCs with the risk of cardiac events (CEs) in women with LQTS.

Risk Prediction in Women With Congenital Long QT Syndrome.

Background We aimed to provide personalized risk estimates for cardiac events (CEs) and life-threatening events in women with either type 1 or type 2 long QT. Methods and Results The prognostic model was derived from the Rochester Long QT Syndrome Registry, comprising 767 women with type 1 long QT (n=404) and type 2 long QT (n=363) from age 15 through 60 years. The risk prediction model included the following variables: genotype/mutation location, QTc-specific thresholds, history of syncope, and β-blocker therapy.

Predictors of Atrial Fibrillation During Long-Term Implantable Cardiac Monitoring Following Cryptogenic Stroke.

Background Following cryptogenic stroke, guidelines recommend cardiac monitoring for occult atrial fibrillation (AF). We aimed to evaluate predictors of AF during long-term implantable cardiac monitoring. Methods and Results We studied 293 consecutive patients who underwent implantable cardiac monitor implant (Medtronic LINQ) following hospitalization for cryptogenic stroke at the University of Rochester Medical Center from January 2013 to September 2018.

Fish and omega-3 fatty acid consumption and risk of hypertension.

Background: Experimental studies suggest that omega-3 fatty acid have favorable effects on blood pressure (BP). However, data on the association of long-term dietary intake of omega-3 fatty acid or fish with risk of hypertension in healthy subjects are sparse. We examined whether fish or omega-3 fatty acid consumption was associated with incident hypertension in the Physicians' Health Study (PHS).

Impact of non-cardiovascular disease burden on thirty-day hospital readmission in heart failure patients.

Background: Little is known about the impact of non-cardiovascular disease (CVD) burden on 30- -day readmission in heart failure (HF) patients. The aim of the study was to assess the role of non-CVD burden on 30-day readmission in HF patients. \ METHODS: We analyzed the effect of non-CVD burden by frequency of ICD-9 code categories on readmis-sions of patients discharged with a primary diagnosis of HF.

Ambulatory Intra Aortic Balloon Pump in Advanced Heart Failure.

Cardiac transplantation is the gold standard treatment for patients with advanced congestive heart failure that is refractory to maximal medical therapy. However, donor heart availability remains the major limiting factor, resulting in a large number of patients waiting long periods of time before transplantation. As a result, mechanical circulatory support devices have been increasingly used as a 'bridge' in order to sustain organ function and stabilise haemodynamics while patients remain on the transplant waiting list or undergo left ventricular assist device surgery.

Device-Directed Therapy for Resistant Hypertension.

Hypertension remains a significant risk factor for an array of diseases despite advancements in pharmacotherapy. Patients with resistant hypertension who do not respond to conventional medical treatments and lifestyle modifications are especially at risk for poor health outcomes. With the increasing awareness of resistant hypertension, ever-evolving research efforts continue to focus on innovative interventions, including renal denervation, median nerve stimulation, and baroreceptor activation therapy.

Present and Future of Interventional Treatment of Resistant Hypertension.

The increasing prevalence of hypertension, a significant cause of disability and premature death throughout the world, is a major public health concern. This is especially true for the subset of patients who suffer from resistant hypertension, which is associated with a fourfold greater risk of cardiovascular events as compared to those hypertensive patients able to achieve target blood pressure. Though quite daunting in number and ill effect, hypertension remains the most common and the most important modifiable risk factor for coronary heart disease, congestive heart failure, peripheral vascular disease, stroke, and chronic kidney disease.

Baroreceptor Stimulation for Resistant Hypertension.

Hypertension (HTN) is a worldwide epidemic. When untreated, HTN places patients at an elevated risk for several health conditions, including cardiovascular disease and end-organ damage. This effect is particularly pronounced in a subset of patients who experience treatment-resistant HTN despite the utilization of conventional medication and lifestyle interventions.

Predictors and clinical relevance of ventricular tachyarrhythmias in ambulatory patients with a continuous flow left ventricular assist device.

Background: Patients with a left ventricular assist device (LVAD) are at high risk for ventricular tachyarrhythmias (VTAs).

Objective: We aimed to identify clinical predictors of VTAs and subsequent outcomes after VTA in ambulatory LVAD patients.

Methods: A retrospective study of 149 patients with a continuous flow HeartMate II LVAD who survived to discharge from index hospitalization after LVAD implantation was performed from January 10, 2005, to September 3, 2013.

Bone mineralization defects after treatment of acute lymphoblastic leukemia ın children.

Aim: Aim of the study was to assess bone metabolism disturbances in children with acute lymphoblastic leukemia following cessation of chemotherapy. For this purpose we measured bone mineral density (BMD) and evaluated bone metabolism markers.

Methods: Seventy-five patients (37 female, 38 males, mean age 10.

A Rare Cause of Prepubertal Gynecomastia: Sertoli Cell Tumor.

Prepubertal gynecomastia due to testis tumors is a very rare condition. Nearly 5% of the patients with testicular mass present with gynecomastia. Sertoli cell tumors are sporadic in 60% of the reported cases, while the remaining is a component of multiple neoplasia syndromes such as Peutz-Jeghers syndrome and Carney complex.

Changes in platelet indices in children with bicuspid aortic valve.

Mean platelet volume (MPV) and platelet distribution width (PDW) can help diagnose cardiovascular pathologies. In this study, we aimed to demonstrate the changes in platelet (PLT) indices in children diagnosed with bicuspid aortic valve (BAV) with mild stenosis and without stenosis to compare patients with mild stenosis with those without stenosis. A total of 73 children diagnosed with BAV (30 patients with mild stenosis and 43 without stenosis) with a mean age 9.

Myeloid sarcoma presenting with leukemoid reaction in a child treated for acute lymphoblastic leukemia.

Background. Myeloid sarcoma is an extramedullary neoplasm of immature myeloid cells. Our study reports a presentation of myeloid sarcoma which presented with severe leukemoid reaction as a secondary malignancy in a patient who was treated for acute lymphoblastic leukemia previously.

A trombosis story and PRES.

Trombosis is seen in children with acute lymphoblastic leukemia during or after L-asparaginase treatment. Posterior reversible encephalopathy syndrome (PRES) is a complex syndrome characterized with sudden hypertension, headache, nausea, vomiting, alteration in the state of consciousness, vision defect and seizures. The cases related to this syndrome have been reportedly seen after eclampsia, organ transplantation, immunsuppressive treatments, autoimmune diseases and chemotherapy.

Seroconversion status after single dose and double doses of varicella vaccination in children with leukemia.

Although varicella is a benign self-limiting disease in healthy children, it can be fatal when it occurs in immunocompromised hosts. Despite that immunosuppressed children are suggested to require 2 doses of vaccine to achieve seroconversion, conflicting results are reported in the literature. The aim of this study was to investigate the seroconversion status and mean antibody titers at first year after single dose and double doses of varicella vaccination in acute lymphoblastic leukemia patients.
