Background: The aim of the present study was to examine whether exercise blood pressure can be used to predict the development of hypertension in normotensive middle‐aged adults. Methods and Results: We investigated 7082 normotensive subjects who were annually screened in a tertiary medical center and completed maximal treadmill exercise tests at each visit. After the initial 3 years, subjects were divided into approximate quartiles according to their average exercise systolic and diastolic blood pressure responses (≤158; 158 to 170; 170 to 183; ≥183 mm Hg for systolic blood pressure and ≤73; 73 to 77; 77 to 82; ≥82 mm Hg for diastolic blood pressure). Mean age of the study population was 48±9 years and 73% were men. Average baseline resting blood pressure was 120/77±12/7 mm Hg. During a follow‐up of 5±3 years, 1036 (14.6%) subjects developed hypertension. The cumulative probability of new‐onset hypertension at 5 years was significantly increased with increasing quartiles of exercise systolic blood pressure (5%, 9%, 17%, and 35%, respectively; P <0.001), with a similar association shown for diastolic blood pressure. After adjustment for baseline resting blood pressure and clinical parameters, each 5‐mm Hg increments in exercise either systolic or diastolic blood pressures were independently associated with respective 11% ( P <0.001) and 30% ( P <0.001) increased risk for the development of hypertension. Conclusions: In normotensive middle‐aged individuals, blood pressure response to exercise is associated with future development of hypertension.

Morphea and other scleroderma-like skin conditions are occasionally linked with exposure to chemical compounds such as silicone. We treated a 56-year-old woman with generalized severe skin induration accompanied with systemic symptoms and peripheral eosinophilia, which appeared 2.5 years after breast silicone implantation and abdominal liposuction. Blood test results and histopathological examination of her skin suggested the diagnosis of morphea overlapping with eosinophilic fasciitis. Her skin disease was presumed to be an autoimmune reaction to silicone implantation. While the removal of the implants did not improve her illness, treatment with 1 mg/kg prednisone and PUVA bath was initiated, with some improvement. This patient illustrates an example of ASIA (Autoimmune Syndrome Induced by Adjuvants), as her disease appeared following exposure to an adjuvant stimulus, with ‘typical’, although not well-defined, autoimmune manifestations.

The role of donor/recipient gender matching on the long-term rejection process and clinical outcomes following heart transplantation (HT) outcomes is still controversial. We aim to investigate the impact of gender matching on early and long-term outcome HT. The study population comprised 166 patients who underwent HT between 1991 and 2013 and were prospectively followed up in a tertiary referral centre. Early and late outcomes were assessed by the type of donor–recipient gender match (primary analysis: female donor–male recipient [FD–MR, n = 36] vs. male donor–male recipient [MD–MR, n = 109]). Early mortality, need for inotropic support, length of hospital stay, and major perioperative adverse events did not differ between the FD–MR and MD–MR groups. However, the FD–MR group experienced significantly higher rates of early major rejections per patient as compared with the MD–MR group (1.2 ± 1.6 vs. 0.4 ± 0.8; P = 0.001), higher rates of overall major rejections (16 vs. 5.5 per 100 person years; P < 0.05), and higher rate of cardiac allograft vasculopathy (43% vs. 20%; P = 0.01). Kaplan–Meier survival analysis showed that the cumulative probabilities of survival free of rejections and major adverse events were significantly higher in MD–MR group (P = 0.002 and 0.001, respectively). Multivariate analysis showed that FD–MR status was associated with >2.5-fold (P = 0.03) increase in the risk for rejections and with a >3-fold (P = 0.01) increase in the risk for major adverse events during follow-up. Donor–recipient gender mismatch is a powerful independent predictor of early and late rejections and long-term major adverse events following HT.

Summary: It was the study objective to evaluate whether chewing a 180 mg loading dose of ticagrelor versus an equal dose of traditional oral administration, enhances inhibition of platelet aggregation 1 hour (h) after administering a ticagrelor loading dose in non-ST elevation myocardial infarction (NSTEMI) patients. Dual anti-platelet therapy represents standard care for treating NSTEMI patients. Ticagrelor is a direct acting P2Y12 inhibitor and, unlike clopidogrel and prasugrel, does not require metabolic activation. Fifty NSTEMI patients were randomised to receive either a chewing loading dose of 180 mg ticagrelor or an equal standard oral dose of ticagrelor. Platelet reactivity was evaluated by VerifyNow at baseline, 1 and 4 h post-loading dose. Results are reported in P2Y12 reaction units. Patients then continued to receive standard 90 mg oral ticagrelor twice daily. Baseline characteristics did not differ between the two groups. P2Y12 reaction units in the chewing group compared with the standard group at 0, 1 and 4 h after ticagrelor loading dose were: 245 vs 239 (p=0.59), 45 vs 130 (p=0.001) and 39 vs 60 (p=0.12), respectively, corresponding to a relative inhibition of platelet aggregation of 83 % vs only 47 % at 1 h (p< 0.001), and 84 % vs 77 % (p=0.59) at 4 h. Major adverse cardiac and cardiovascular events at 30 days were low (2 %), occurring in only one patient in the standard group. In conclusion, chewing a 180 mg ticagrelor loading dose is feasible and facilitates both faster and improved early inhibition of platelet aggregation in NSTEMI patients, compared with a standard oral-loading dose.Supplementary Material to this article is available online at www.thrombosis-online.com.

Significance: The strengthening of heart contraction by epinephrine (adrenaline) and norepinephrine starts with the activation of β-adrenergic receptors and culminates in a protein kinase A–mediated increase in Ca ²⁺ influx through the voltage-gated Ca ²⁺ channel, Ca _V 1.2, into cardiomyocytes. Many crucial molecular details of this vital physiological regulation remained enigmatic for decades, not the least owing to the difficulty of reconstituting the regulation in model cells. Capitalizing on the recent discovery of the central role of the Ca _V 1.2-associated protein, Rad, we present a report of full reconstitution of the β-AR–Ca _V 1.2 cascade in a model system, the Xenopus oocyte, and investigate crucial aspects of regulation such as the roles of auxiliary subunits and diverse forms of the channel protein.
