Michel Burnier, Grégoire Wuerzner
In the last 2 years, the attention of hypertension specialists has been focused on the results of the SPRINT trial and its post-hoc analyses and its possible implications for the management of hypertensive patients. While waiting for new European hypertension guidelines due in 2018, the year 2017 can be considered as a year of transition. Yet, several interesting clinical studies have been published which may affect the future management of hypertension. Thus we shall discuss new data on the benefits of eating more fruits and vegetables on cardiovascular mortality, the « quadpill » concept, the impact of various non-steroidal anti-inflammatory drugs on blood pressure and the most recent data on renal denervation...

AIMS/HYPOTHESIS: A new class of treatments termed bioelectronic medicines are now emerging that aim to target individual nerve fibres or specific brain circuits in pathological conditions to repair lost function and reinstate a healthy balance. Carotid sinus nerve (CSN) denervation has been shown to improve glucose homeostasis in insulin-resistant and glucose-intolerant rats; however, these positive effects from surgery appear to diminish over time and are heavily caveated by the severe adverse effects associated with permanent loss of chemosensory function...

This manuscript describes the first report of takotsubo cardiomyopathy in a young heart transplant recipient following angry debate. Our patient is a 21-year-old woman with cardiac transplant performed owing to right ventricular failure in congenital heart disease. Positive echocardiography with typical asymmetry of regional function, positive enzymes, and negative biopsy and angiography met the criteria for the diagnosis of takotsubo cardiomyopathy. Patient was discharged after 1 week in good clinical conditions and fully recovered cardiac function...

OBJECTIVE: To evaluate efficacy of denervation of the of the hip joint capsule (HJC), as a treatment of hip joint pain. Specifically, we tested the hypothesis that HJC denervation will significantly reduce the number of sensory neurons innervating the capsule. STUDY DESIGN: Denervation of the HJC from a medial or lateral approach was followed by retrograde tracing of sensory neurons innervating the capsule. ANIMALS: Twenty adult male sheep (30-40 kg of body weight; Polish merino breed) were used in the study...

The aging process is characterized by a decline in several physiological functions resulting in a reduced capability to maintain homeostasis. The lowered homeostatic capacity seems to involve the carotid body (CB), whose role is to modulate ventilation and tissue oxygen supply, thus playing a prime role in all aging processes. Aging causes marked changes in CB morphology. Indeed, it is enlarged and shows a concomitant decrease in the percentage of chemoreceptor tissue, as well as a proliferation of Type II cells...

BACKGROUND: Although chronic kidney disease (CKD) is an independent risk factor for stroke, official recommendations for the primary prevention of stroke in CKD are generally lacking. SUMMARY: We searched PubMed and ISI Web of Science for randomised controlled trials, observational studies, reviews, meta-analyses and guidelines referring to measures of stroke prevention or to the treatment of stroke-associated risk factors (cardiovascular disease in general and atrial fibrillation (AF), arterial hypertension or carotid artery disease in particular) among the CKD population...

Renal denervation and spironolactone have both been proposed for the treatment of resistant hypertension, but their effects on preclinical target organ damage have not been compared. Twenty-four patients with 24-hour systolic blood pressure ≥140 mm Hg despite receiving three or more full-dose antihypertensive drugs, one a diuretic, were randomized to receive spironolactone or renal denervation. Changes in 24-hour blood pressure, urine albumin excretion, arterial stiffness, carotid intima-media thickness, and left ventricular mass index were evaluated at 6 months...

The effects of lung afferents denervation on cardiovascular regulation can be assessed on bilateral lung transplantation patients. The high-frequency component of heart rate variability is known to be synchronous with breathing frequency. Then, if heart beat is neurally modulated by breathing frequency, we may expect disappearance of high frequency of heart rate variability in bilateral lung transplantation patients. On 11 patients and 11 matching healthy controls, we measured R-R interval (electrocardiography), blood pressure (Portapres® ) and breathing frequency (ultrasonic device) in supine rest, during 10-min free breathing, 10-min cadenced breathing (0·25 Hz) and 5-min handgrip...

Mice subjected to cold or caloric deprivation can reduce body temperature and metabolic rate and enter a state of torpor. Here we show that administration of pyruvate, an energy-rich metabolic intermediate, can induce torpor in mice with diet-induced or genetic obesity. This is associated with marked hypothermia, decreased activity, and decreased metabolic rate. The drop in body temperature correlates with the degree of obesity and is blunted by housing mice at thermoneutrality. Induction of torpor by pyruvate in obese mice relies on adenosine signaling and is accompanied by changes in brain levels of hexose bisphosphate and GABA as detected by mass spectroscopy-based imaging...

BACKGROUND: Herpes zoster is an illness which is especially common amongst the elderly in the Netherlands and which can express itself in various ways. Besides affecting sensory nerves, which leads to postherpetic pain, the varicella zoster virus may also invade motor nerves. CASE DESCRIPTION: A 73-year-old female went to the surgeon with symptoms of a painful swelling in the left lower abdomen. She had experienced herpes zoster at the site of the swelling a few months earlier...

The use of pectoralis major muscle (PMM) in breast reconstruction has been a mainstay for decades. In recent years, although, a novel approach, the so-called subcutaneous or pre-pectoral breast reconstruction, has been introduced advocating the advantages of sparing the pectoralis muscle. Such advantages include more natural implant ptosis and appearance, significant reduction of capsular contracture and also avoidance of implant animation and animation deformities. These are all drawbacks that the use of muscles in implant coverage inevitably involves overtime...

Functional Electrical Stimulation (FES) can elicit muscular contraction and restore motor function in paralyzed limbs. FES is a rehabilitation technique applied to various sensorimotor deficiencies and in different functional situations, e.g. grasping, walking, standing, transfer, cycling and rowing. FES can be combined with mechanical devices. FES-assisted cycling is mainly used in clinical environments for training sessions on cycle ergometers, but it has also been adapted for mobile devices, usually tricycles...

Cervical spinal cord injuries (SCI) result in devastating functional consequences, including respiratory dysfunction. This is largely due to the disruption of phrenic pathways, which control the diaphragm. Recent work has identified spinal interneurons as possible contributors to respiratory neuroplasticity. The present work investigated whether transplantation of developing spinal cord tissue, inherently rich in interneuronal progenitors, could provide a population of new neurons and growth permissive substrate to facilitate plasticity and formation of novel relay circuits to restore input to the partially denervated phrenic motor circuit...

Resistant hypertension (RH) can be diagnosed if blood pressure (BP) is not controlled with the combination of three antihypertensive drugs, including a diuretic, all at effective doses. Patients affected by this condition exhibit a marked increase in the risk of cardiovascular and renal morbid and fatal events. They also exhibit an increased activity of the sympathetic nervous system which is likely to importantly contribute at the renal and other vascular levels to the hypertensive state. Almost 10years ago renal denervation (RDN) by radiofrequency thermal energy delivery to the walls of the renal arteries was proposed for the treatment of RH...

Tourette syndrome (TS) is a neuropsychiatric disorder with the onset in childhood. TS is a form of tic disorders, and characterized by the motor and vocal tics, and comorbidities such as attention deficit hyperkinetic and obsessive compulsive disorders. These symptoms appear age dependently, showing a wax and wane course, and subside or abolish by the late teens. Pathophysiology of TS involves the dysfunction of both motor and non-motor basal ganglia-thalamo-cortical circuitries. The nigrostriatal dopamine (DA) system takes the exponential decrement at the striatum...

Renal sympathetic denervation (RDN) is currently being investigated in multiple studies of heart failure (HF). Our aim was to assess the safety and effectiveness of RDN in patients with HF, and determine which patients could achieve more beneficial effects of RDN. A total of 17 consecutive patients with HF were enrolled in the study. Clinical symptoms, office blood pressure, and laboratory results were obtained and echocardiography was performed before and 12 months after RDN. Changes from baseline to 12 months were analyzed for all patients and for two subgroups based on HF duration (group 1: HF duration ≤ 3 years, n = 9; group 2: HF duration > 3 years, n = 8)...

INTRODUCTION: The most common form of spinal muscular atrophy (SMA) is a recessive disorder caused by SMN1 mutations in 5q13, whereas the genetic etiologies of non-5q SMA are very heterogenous and largely remain to be elucidated. We present a father and son with atrophy and weakness of the lower leg muscles since infancy. Genetic studies in this family revealed a novel BICD2 mutation causing autosomal dominant lower extremity-predominant SMA type 2. PATIENTS: The proband was the father, aged 30, and the son was aged 3...
