Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.

Sino-aortic denervation augments the increase in blood pressure seen during paradoxical sleep in the rat. (1/71)

Using a computer assisted telemetric system, we have re-examined the effect of sino-aortic denervation (SAD) on the changes in arterial blood pressure (AP) and heart rate (HR) during sleep in the rat suitably recovered from the operation. Eight 1 hourly polygraphic recordings were performed 4 weeks after the initial SAD surgery. In the SAD rats, the increase in AP during paradoxical sleep (PS) was much larger than that in sham-operated rats. HR in the SAD rats increased on-going from slow-wave sleep to PS, but it showed no change in sham-operated rats. The present study suggests that chronic SAD causes the enhanced AP increase during PS concomitantly with the persistent hypertension and tachycardia across sleep-wake states.  (+info)

Autonomic control of skeletal muscle blood flow at the onset of exercise. (2/71)

The purpose of this study was to determine whether the autonomic nervous system is involved in skeletal muscle vasodilation at the onset of exercise. Mongrel dogs (n = 7) were instrumented with flow probes on both external iliac arteries. Before treadmill exercise at 3 miles/h, 0% grade, hexamethonium (10 mg/kg) and atropine (0.2 mg/kg) or saline was infused intravenously. Ganglionic blockade increased resting heart rate from 87 +/- 5 to 145 +/- 8 beats/min (P < 0.01) and reduced mean arterial pressure from 100 +/- 4 to 88 +/- 5 mmHg (P < 0.01). During steady-state exercise, heart rate was unaffected by ganglionic blockade (from 145 +/- 8 to 152 +/- 5 beats/min), whereas mean arterial pressure was reduced (from 115 +/- 4 to 72 +/- 4 mmHg; P < 0.01). Immediate and rapid increases in iliac blood flow and conductance occurred with initiation of exercise with or without ganglionic blockade. Statistical analyses of hindlimb conductance at 5-s intervals over the first 30 s of exercise revealed a statistically significant difference between the control and ganglionic blockade conditions at 20, 25, and 30 s (P < 0.01) but not at 5, 10, and 15 s of exercise. Hindlimb conductance at 1 min of exercise was 9.21 +/- 0.68 and 11.82 +/- 1.32 ml. min(-1). mmHg(-1) for the control and ganglionic blockade conditions, respectively. Because ganglionic blockade did not affect the initial rise in iliac conductance, we concluded that the autonomic nervous system is not essential for the rapid vasodilation in active skeletal muscle at the onset of exercise in dogs. Autonomic control of skeletal muscle blood flow during exercise is manifested through vasoconstriction and not vasodilation.  (+info)

The influence of acute hypoxia and carotid body denervation on thermoregulation during non-rapid eye movement sleep in the developing lamb. (3/71)

We investigated the influence of ambient temperature on the thermoregulatory response to hypoxia in developing lambs before (at 4 and 14 days of age) and after (17 and 30 days of age) carotid body denervation (CBD). Lambs were studied during non-rapid eye movement sleep at thermoneutral (23-15 C) and cool (10-5 C) ambient temperatures, during normoxia and acute hypoxia (inspired oxygen content of 13 %). Measurements of oxygen consumption, arterial partial pressures of O2 and CO2, colonic temperature, incidence of shivering and plasma concentrations of thyroid hormones, cortisol, insulin and glucose were made under each condition. Oxygen consumption was higher at cool compared with thermoneutral ambient temperatures and decreased during hypoxia during cooling at all stages. At 4 days of age, only one lamb shivered during cooling in normoxia, but 4 out of 12 lambs shivered during hypoxia and colonic temperature fell, significantly, by 0.2 C. At 14 days, 8 out of 12 lambs shivered during cooling, of which 6 continued to shiver during hypoxia but colonic temperature did not change significantly. Plasma triiodothyronine concentrations increased on cooling at 4 and 14 days, an affect that was inhibited by hypoxia at 4, but not 14 days of age. At 17 days of age, i.e. post-CBD, plasma thyroid hormone concentrations and oxygen consumption were lower during cold exposure compared with intact lambs at 14 days of age. In CBD lambs, imposing further hypoxia resulted in colonic temperature falling 0. 6 C during cooling, with only 2 out of 10 lambs shivering. Plasma glucose and insulin, but not cortisol, concentrations decreased during hypoxia, irrespective of age or CBD. It is concluded that hypoxia has an important influence on metabolism and thermoregulation, which is modulated by age and environmental conditions. Compromised carotid body function, in lambs older than 2 weeks of age, can result in severe hypoxia and thermoregulatory dysfunction even with modest environmental cooling.  (+info)

Ileal short-chain fatty acids inhibit gastric motility by a humoral pathway. (4/71)

The aim of this study was to evaluate the nervous and humoral pathways involved in short-chain fatty acid (SCFA)-induced ileal brake in conscious pigs. The role of extrinsic ileal innervation was evaluated after SCFA infusion in innervated and denervated Babkin's ileal loops, and gastric motility was measured with strain gauges. Peptide YY (PYY) and glucagon-like peptide-1 (GLP-1) concentrations were evaluated in both situations. The possible involvement of absorbed SCFA was tested by using intravenous infusion of acetate. Ileal SCFA infusion in the intact terminal ileum decreased the amplitude of distal and terminal antral contractions (33 +/- 1.2 vs. 49 +/- 1.2% of the maximal amplitude recorded before infusion) and increased their frequency (1.5 +/- 0.11 vs. 1.3 +/- 0.10/min). Similar effects were observed during SCFA infusion in ileal innervated and denervated loops (amplitude, 35 +/- 1.0 and 34 +/- 0. 8 vs. 47 +/- 1.3 and 43 +/- 1.2%; frequency, 1.4 +/- 0.07 and 1.6 +/- 0.06 vs. 1.1 +/- 0.14 and 1.0 +/- 0.12/min). Intravenous acetate did not modify the amplitude and frequency of antral contractions. PYY but not GLP-1 concentrations were increased during SCFA infusion in innervated and denervated loops. In conclusion, ileal SCFA inhibit distal gastric motility by a humoral pathway involving the release of an inhibiting factor, which is likely PYY.  (+info)

c-Fos expression in the midbrain periaqueductal gray during static muscle contraction. (5/71)

The periaqueductal gray (PAG) of the midbrain is involved in the autonomic regulation of the cardiovascular system. The purpose of this study was to determine if static contraction of the skeletal muscle, which increases arterial blood pressure and heart rate, activates neuronal cells in the PAG by examining Fos-like immunoreactivity (FLI). Muscle contraction was induced by electrical stimulation of the L7 and S1 ventral roots of the spinal cord in anesthetized cats. An intravenous infusion of phenylephrine (PE) was used to selectively activate arterial baroreceptors. Extensive FLI was observed within the ventromedial region (VM) of the rostral PAG, the dorsolateral (DL), lateral (L), and ventrolateral (VL) regions of the middle and caudal PAG in barointact animals with muscle contractions, and in barointact animals with PE infusion. However, muscle contraction caused a lesser number of FLI in the VM region of the rostral PAG, the DL, L, and VL regions of the middle PAG and the L and VL regions of the caudal PAG after barodenervation compared with barointact animals. Additionally, the number of FLI in the DL and L regions of the middle PAG was greater in barodenervated animals with muscle contraction than in barodenervated control animals. Thus these results indicated that both muscle receptor and baroreceptor afferent inputs activate neuronal cells in regions of the PAG during muscle contraction. Furthermore, afferents from skeletal muscle activate neurons in specific regions of the PAG independent of arterial baroreceptor input. Therefore, neuronal cells in the PAG may play a role in determining the cardiovascular responses during the exercise pressor reflex.  (+info)

Hepatic parasympathetic (HISS) control of insulin sensitivity determined by feeding and fasting. (6/71)

In response to insulin, a hormone [hepatic insulin sensitizing substance (HISS)] is released from the liver to stimulate glucose uptake in skeletal muscle but not liver or gut. The aim was to characterize dynamic control of HISS action in response to insulin and regulation of release by hepatic parasympathetic nerves. Insulin action was assessed by the rapid insulin sensitivity test, where the index is the glucose required (mg/kg) to maintain euglycemia after a bolus of insulin. Blocking HISS release by interruption of the hepatic parasympathetic nerves by surgical denervation, atropine, or blockade of hepatic nitric oxide synthase produced similar degrees of insulin resistance and revealed a similar dynamic pattern of hormone action that began 3--4 min after, and continued for 9--10 min beyond, insulin action (50 mU/kg). HISS action accounted for 56.5 +/- 3.5% of insulin action at insulin doses from 5 to 100 mU/kg (fed). We also tested the hypothesis that HISS release is controlled by the feed/fast status. Feeding resulted in maximal HISS action, which decreased progressively with the duration of fasting.  (+info)

Nitric oxide-dependent in vitro secretion of amylase from innervated or chronically denervated parotid glands of the rat in response to isoprenaline and vasoactive intestinal peptide. (7/71)

The basal in vitro release of amylase was similar from rat parotid lobules of innervated and chronically denervated glands and was unaffected by the inhibitors used in this study. The secretion of amylase induced by isoprenaline or vasoactive intestinal peptide (VIP) was reduced by one-third to one-half from the lobules of the innervated glands and even more so from the lobules of the denervated glands by ODQ, an inhibitor of soluble guanyl cyclase which is activated by nitric oxide (NO) and catalyses the cGMP production. The use of N (omega)-propyl-L-arginine (N-PLA) revealed that the evoked secretion of amylase in the denervated glands depended on the activity of neuronal type NO synthase to synthesize NO. Since the denervated gland is virtually devoid of NO synthase-containing nerve fibres, the neuronal type NO synthase was most probably of a non-neuronal source. NO-dependent amylase secretion was agonist related, since amylase secretion evoked by bethanechol and neuropeptide Y was not reduced by ODQ or N-PLA. Hence, under physiological conditions, activation of beta-adrenoceptors (sympathetic activity) and VIP receptors (parasympathetic activity) is likely to cause secretion of parotid amylase partly through a NO/cGMP-dependent intracellular pathway involving the activity of neuronal type NO synthase, possibly of acinar origin.  (+info)

Heartbeat control in leeches. II. Fictive motor pattern. (8/71)

The rhythmic beating of the tube-like hearts in the medicinal leech is driven and coordinated by rhythmic activity in segmental heart motor neurons. The motor neurons are controlled by rhythmic inhibitory input from a network of heart interneurons that compose the heartbeat central pattern generator. In the preceding paper, we described the constriction pattern of the hearts in quiescent intact animals and showed that one heart constricts in a rear-to-front wave (peristaltic coordination mode), while the other heart constricts in near unison over its length (synchronous coordination mode) and that they regularly switch coordination modes. Here we analyze intersegmental and side-to-side-coordination of the fictive motor pattern for heartbeat in denervated nerve cords. We show that the intersegmental phase relations among heart motor neurons in both coordination modes are independent of heartbeat period. This finding enables us to combine data from different experiments to form a detailed analysis of the relative phases, duty cycle, and intraburst spike frequency of the bursts of the segmental heart motor neurons. The fictive motor pattern and the constriction pattern seen in intact leeches closely match in their intersegmental and side-to-side coordination, indicating that sensory feedback is not necessary for properly phased intersegmental coordination. Moreover, the regular switches in coordination mode of the fictive motor pattern mimic those seen in intact animals indicating that these switches likely arise by a central mechanism.  (+info)

This is a clinical study looking at the effectiveness and safety of a new device call The Paradise System to use for renal denervation in patients who have mild to resistant hypertension. The study is divided into two groups, those on one to two anti hypertensive medications and those on three or more. For those only taking one or two medications, they will stop their current blood pressure medication while monitoring their blood pressure. Those who are taking 3 or more blood pressure medications will stop their current medication regime and be given one of two combination medications while monitoring their blood pressure. In each of the groups have the patients, if and when they continue to meet study inclusion criteria, will be randomized to undergo a renal denervation procedure using the new system vs no procedure. Their assignment will not be made known to them. All groups will be follow up to 3 years but for patients who did not initially have the procedure will be allowed to do so after ...
In SPYRAL HTN OFF-MED renal denervation patients, the 24-hour systolic ambulatory blood pressure (ABPM) declined 5.5mmHg, resulting in a 5mmHg difference from the sham control arm (p=0.041), and the diastolic AMBP declined 4.8mmHg, resulting in a 4.4mmHg difference from the sham control arm (p=0.002). Additionally, there were no reported cases of new or worsening renal failure, vascular complications, or other major adverse events, confirming the safety of the renal denervation procedure - even with a revised procedural approach that extended ablations into the kidneys branch arteries and an increase in total number of ablations compared with previous trials.. After SYMPLICITY HTN-3, we learned a lot about the procedure itself, medication adherence and which patients may have less response to the renal denervation procedure-these insights have been incorporated into the revised clinical approach in the SPYRAL HTN program, said co-principal investigator David Kandzari, director of ...
The results of the present study support the conclusion that in rats, the arterial baroreceptor reflex largely mediates the stress-induced increases in Mayer waves and associated RSNA oscillations. In rats with chronic SAD, stress enhances fluctuations of MAP and RSNA in the frequency band containing Mayer waves but does not unmask any predominant rhythmicity at Mayer waves frequency.. In baroreceptor-intact and SAD rats, a continuous jet of air blown into the cage increased RSNA and MAP, which is characteristic of the defense reaction in rats.26,27 In SAD rats, although the stress-induced increase in RSNA was similar to that observed in control rats, the increase in MAP was larger. The latter finding accords with a previous report.22 These differential effects of stress on MAP were not related to cardiac factors because the autonomic innervation of the heart had been blocked. Stress did not markedly alter the gain of the transfer function between RSNA and MAP in SAD rats, which suggests that ...

Endometriosis describes deposits of ectopic endometrium outside the uterus. Traditionally, gynaecologists believe that these deposits of endometrium bleed during your period and cause pain. A better explanation is that the pain is caused by injuries to your pelvic nerves and the endometrium simply attaches to areas of injury in your pelvis. These injuries are caused by difficult first labours, straining on the toilet, and, gynaecological surgery (GS Atwal, 2005).. Endometriosis was first described in 1860 though it has had many reincarnations since that date. The theory associated with deposits of ectopic endometrium has, therefore, had 150 years to cement itself into medical minds and habits. Injured nerves were discovered in 2005 ! So it is going to take a little while to change hearts and minds ? And it is not going to be easy because many doctors make very large sums of money ablating, or excising, ectopic endometrium.. What is the evidence that ectopic endometrium causes cyclical, ...
A renal denervation system includes an ablation catheter and an inflation balloon. The renal denervation catheter is insertable into a renal artery to perform a renal denervation procedure. The inflation balloon is inflatable within the renal artery, wherein one of a blood pressure condition in the renal artery resulting from operation of the inflation balloon and a performance characteristic of the inflation balloon indicates efficacy of the renal denervation procedure.
Despite large reductions in blood pressure seen in early studies of renal denervation, the SYMPLICITY HTN-3 randomized trial failed to show a reduction in systolic blood pressure with renal denervation when compared to medical therapy alone. As a result, interest in renal denervation as a treatment for resistant hypertension has waned. In the DENERHTN trial, Azizi and colleagues assessed the incremental benefit of adding renal denervation to standardized stepped-care antihypertensive treatment (SSAHT) for patients with resistant hypertension in an open-label, randomized-controlled trial with blinded endpoint evaluation. After four weeks of a standardized anti-hypertensive regimen to confirm resistant hypertension, patients were randomized to renal denervation in addition to SSAHT versus SSAHT alone. The primary endpoint was the mean change in daytime systolic blood pressure after six months as assessed by ambulatory monitoring. Of the 106 patients randomized (53 in each group), 101 had endpoints ...

Renal denervation with ultrasound after performed after prior denervation with radiofrequency seems to be safe. After an initial decrease of blood pressure after one month, we observed an increase in blood pressure in this small number of patients, a finding which has not been seen in other denervation studies, said Sievert.. RETREAT is a physician-initiated prospective, multicentre study with no industry funding in which 30 patients will be enrolled. Its purpose is to evaluate the effect of renal denervation using ultrasound energy (with Recors Paradise system) after failed denervation with radiofrequency (with Medtronics Symplicity system).. Sievert said: Enrolment in the RETREAT study coincided with the publication of the SYMPLICITY HTN-3 study results following which the reimbursement for renal denervation was stopped in Germany. There was a decline in referrals for renal denervation and new treatment modalities for hypertension began to be explored. This resulted in enrolment becoming ...
Covidien [1] plc has announced it will exit its OneShot Renal Denervation program. This voluntary action is primarily in response to slower than expected development of the renal denervation market.. The OneShot system is an over-the-wire balloon-based irrigated catheter technology for the treatment of hypertension. The system received CE Mark in February 2012 and is not approved for sale in the United States.. This decision resulted from Covidiens regular review of strategic programs and growth potential for various aspects of its product portfolio.. As a result of this decision the company will not proceed with its RAPID II randomized study. Additionally, Covidien expects to record after-tax charges in the range of $20 to $25 million as a result of exiting the OneShot program.. Over the next several weeks, the company will collaborate with physicians and the renal denervation community to ensure existing OneShot patients are informed and the currently enrolling clinical trials are ...
Introduction. Hypertension is one of the most common chronic clinical problems encountered by physicians. Resistant hypertension is defined as systolic blood pressure (BP) ≥160 mmHg or (≥150 mmHg in patients with type 2 diabetes mellitus) refractory to medical treatment despite the use of optimal doses of three or more different drug types including a diuretic.1 The prevalence of resistant hypertension is estimated at 9% in the US.2 In a study of 205750 treated hypertensive patients, 1 in 50 developed resistant hypertension within a median of 1.5 years from the initial treatment.3 In the same study, patients with resistant hypertension were shown to be at higher risk for adverse cardiovascular events.3 The increased morbidity and mortality associated with this condition supports greater efforts to improve treatment options.. Historical perspective. After a link was established between the sympathetic nervous system and the development of resistant hypertension, surgical sympathectomy was ...
The Symplicity HTN-3 study is a, multi-center, prospective, single-blind, randomized, controlled study of the safety and effectiveness of renal denervation in subjects with uncontrolled hypertension. Bilateral renal denervation will be performed using the Symplicity Catheter - a percutaneous system that delivers radiofrequency (RF)energy through the luminal surface of the renal artery ...
Sinus tachycardia is due to rapid firing of a normal structure called the sinoatrial (sinus) node which is the natural pacemaker of the heart. Sinus tachycardia occurs in response to exercise, exertion, excitement, pain, fever, excessive thyroid hormone, low blood oxygen (hypoxia), stimulant drugs (such as caffeine and amphetamines), etc. ...

Since Alger Hiss was convicted at his second trial for perjury in 1950, most of the books on the Hiss-Chambers case have been written by partisans of Hiss who believe he was framed; and most have largely rehashed the very evidence available at the trials, using it to attack Chamberss defense of himself in his book Witness. Important new evidence on the case has now become available-not only from FBI and other government files that were previously classified but from the defense records that Hiss himself has opened to me and to other researchers, including John Chabot Smith, the author of Alger Hiss: The True Story.. Unfortunately, Smiths book follows the familiar pattern. He uses little of the new material released by the government. What is worse, he fails even to mention many of the documents in Hisss own files that undermine Hisss claims to have told the truth. Smith tells us that he covered the two Hiss trials for the New York Herald Tribune and has believed ever since that Hiss was the ...

The effect of supradiaphragmatic splanchnicectomy on the blood pressure of 294 hypertensive patients followed for 10 to 18 months after surgery is compared with the effects of nonspecific medical management in a control group of 79 patients similarly studied. The data are presented in simple graphic form. It is concluded that 29 per cent of the hypertensive patients had reductions in blood pressure outside the range of spontaneous variation, that the vascular complications of hypertension decreased the likelihood of a good result, and that extension of the sympathetic ganglionectomy upward appeared to increase the frequency of good results without requiring a two-stage operation or producing significant postoperative orthostatic hypotension.. ...
The CE mark enables Vessix to market its patented V2 System throughout the European Union. The CE certification was issued to Vessix by its notified body, BSI Group, also known as the British Standards Institution.. Vessix offers a unique approach to treating uncontrolled hypertension that provides excellent clinical results and is faster, easier to use and less painful for patients than any renal denervation system currently available in the market, said CEO Raymond W Cohen. After eight years optimising radiofrequency balloon catheter and bipolar radiofrequency generator technologies, it is rewarding to see the V2 System working effectively in clinical practice to safely reduce patient blood pressures. As part of our commercialisation strategy, Vessix has initiated a post-market approval surveillance study during which we plan to treat 120 patients at up to 20 international centers located across Western Europe.. Renal denervation has shown in published clinical studies to be safe, durable ...

Renal sympathetic denervation (RSDN), or renal denervation (RDN), is a minimally invasive, endovascular catheter based procedure using radiofrequency ablation or ultrasound ablation aimed at treating resistant hypertension (high blood pressure not controlled by medication).
Results Systolic blood pressure after catheter-based renal denervation decreased by 35.52 ± 17.65, 36.63 ± 18.54 mmHgat 6 months and 1 year, respectively (P , 0.001). Diastolic blood pressure decreased by 15.19 ± 15.44, 16.13 ± 15.51 mmHg, at 6 months, and 1 year, respectively (P , 0.001). Meanwhile, there is a clear positive correlation between NE and the BP reduction (r2 = 0.82, P , 0.001), and a similar correlation between rennin (r2 = 0.72, P , 0.001), AngII (r2 = 0.75, P , 0.001), ALD (r2 = 0.71, P , 0.001), ET-1 (r2 = 0.72, P , 0.001) and the BP reduction was observed in our study. In addition, there is a significantly decline in NE, renin, AngII, ALD and ET-1 (all P , 0.01).. ...

Introduction: Esophageal injury is a potential complication after catheter ablation of the posterior left atrium (LA). Therefore, we describe a new approach for complete isolation of the posterior LA including all pulmonary veins (PVs) without vertical lesions along the esophageal aspect of the posterior LA, namely Box isolation.. Methods and Results: Ninety-one patients with paroxysmal atrial fibrillation (AF) underwent Box isolation. Continuous lesions at the anterior portions of the ipsilateral PVs were initially created and then linear ablation of LA roof and bottom was performed to isolate the posterior LA. Continuous vertical lesions at the posterior portions of PVs along the esophageal aspect of the posterior LA were not created. Ablation was performed with an 8-mm-tip catheter. The endpoint was the absence of electrical activity and the inability to pace the posterior LA and all PVs in sinus rhythm. Complete isolation of the posterior LA was achieved in 82 patients (90%). Ablation ...
Renal nerve ablation has been shown to elicit a chronic, anti-hypertensive effect in drug-resistant hypertensive patients. Precise understanding of the mechanisms underlying the clinical success of renal denervation is currently unknown, and as a consequence, it is predicted the technology will be under-utilized until such information is uncovered. Retrospective multivariate analyses of responders suggest treatment with a central sympatholytic may correlate with a successful response to renal denervation. However, this hypothesis remains untested. This study tested the hypothesis that pretreatment with a central sympatholytic would augment the response to renal denervation (RDX) in the spontaneously hypertensive rat. In rats pre-treated for 1 week with clonidine (125ug/kg/day), MAP was significantly reduced from baseline but there was no difference in response to clonidine between groups (Sham(n=7): -21.3±0.8 vs RDX(n=7): -22.8±1.3mmHg, p,0.05). During clonidine treatment RDX significantly ...
The medical term, Vasovagal Syncope is certainly a mouthful to say and pronounce. If you are wondering, what this very scientific sounding phrase means it is the term that is used to refer to the most common cause of fainting.. Fainting at the Sight of Blood. Up to 15% of the population experiences a sharp drop in blood pressure at the sight of blood, which causes them to experience Vasovagal Syncope, or to faint at the sight of blood. Fainting at the sight of blood is caused by a bodys exaggerated reaction to specific triggers. The sight of blood being one of the most common triggers that causes Vasovagal Syncope.. Medical Reasons Why People Faint at the Sight of Blood. Vasovagal Syncope results when a trigger (sight of blood) causes a sudden drop in the heart rate and blood pressure, which reduces the flow of blood to the brain. The result for an individual experiencing Vasovagal Syncope is a brief loss of consciousness. The Vagus nerve is the nerve affected by the response. This nerve is ...
OBJECTIVE We have previously demonstrated the effectiveness of renal denervation (RDN) to lower blood pressure (BP) at least partially via the reduction of sympathetic stimulation to the kidney. Obesity also contributes to hypertension. A number of adipocyte-derived factors (collectively termed adipokines) have been implicated in BP control. The aim of this study was to examine the effect of RDN on adipokines. In particular, whether BP reduction, associated with RDN treatment, has a favourable outcome on adipokine profile in patients with resistant hypertension (RH). DESIGN AND METHOD Fifty seven patients with RH undergoing RDN have been recruited for the study (65% males, age 60.8 ± 1.5 years, BMI 32.6 ± 0.7 kg/m, mean ± SEM). At recruitment the patients were on an average of 4.8 ± 2.1 antihypertensive drugs and were asked to refrain from changing their medication regimen for the duration of the study. Automated seated office BP measurements were taken with an Omron HEM-705 monitor at baseline
Vasovagal syncope is a benign condition. According to the recent recommendations of the ESC Guidelines on Syncope (3) the patients who seek medical advice after having experienced a vasovagal faint require principally reassurance and education regarding the nature of the condition. In general, initial treatment of all forms of neurally-mediated reflex syncope comprises education regarding avoidance of triggering events (e.g., hot crowded environments, volume depletion, effects of cough, tight collars, etc.), recognition of premonitory symptoms, and manoeuvers to abort the episode. Non-pharmacological physical treatments are arising as a new first choice treatment of vasovagal syncope in patients who have vasovagal syncope preceded by prodromal symptoms and age ,65 years. This approach seems to be very helpful in real life. In 2 follow-up studies (1,2), the manoevres were self-administered by these patients in ,95% of cases and were able to abort syncope in ,95% of patients. No patients had ...
The prevalence of resistant hypertension in this primary care setting is 8.8%. This is lower than that reported in secondary care [8, 32, 33] but is similar to another primary care study [18].. Our findings also show that hypertensive patients with CKD had 2.9 odds of having resistant hypertension compared to those without CKD. This is consistent with findings in other studies [12, 14]. One possible reason is that in patients with CKD, there is increased sensitivity to salt resulting in sodium and fluid retention, thus making BP more difficult to control [34]. Another possible explanation is that in CKD, the RAS system is up regulated resulting in difficult to control BP [35].. Our study sample is made up of older patients as seen from the mean age of 66.9 years. That resistant hypertension is negatively associated with age could be due to the survival effect of fitter patients, whereby those with resistant hypertension had already succumbed to the complications of uncontrolled or resistant ...

I open the door and shes waiting, but usually greats me with a hiss. She will approach me, but Im not allowed to approach her. I have to be careful when I set down the food because shell come over to get it, but scratch me at the same time. So, shes kind of used to people. Normally ferals wont come close and will hide until the food is set out. This all leads me to believe she probably was socialized with humans early in her life and then abandoned and became feral. Her contact with humans was probably only for a short period of time, but long enough that she isnt totally freaked out around them. However, she has taught her kittens well. Whenever she hisses they run and hide.

  • Usually manifesting itself between 20 and 40 years of age, it is characterized by pain, paresthesia, muscular weakness and autonomic dysfunction. (
  • Autonomic dysfunction can occur even in the early stages of PD, often preceding the onset of the classic motor symptoms of PD. (
  • Detection of autonomic dysfunction may therefore be helpful in diagnosing PD in the early or pre-motor stages, and/or in differentiating it from other parkinsonian disorders, such as multiple system atrophy and progressive supuranuclear palsy. (
  • The aim of this review is to describe aspects of autonomic dysfunction, including symptoms, assessment and pathophysiology, resulting from autonomic impairment in PD and other parkinsonian syndromes. (
  • Non-motor features of Parkinson's disease (PD) are increasingly being defined and include dysfunction of the autonomic nervous system. (
  • Autonomic dysfunction was previously reported in the advanced stage of PD but recent evidence suggests it may occur even in the early stage of PD, independent of medication. (
  • 2 These lesions may result in autonomic dysfunction. (
  • Because sympathetic hyperactivity and parasympathetic (cholinergic) derangement are associated with EAT dysfunction leading to a multitude of adverse cardiac conditions, such as heart failure, diastolic dysfunction, atrial fibrillation, etc., a number of recent studies have focused on exploring the autonomic regulation of EAT as it pertains to heart disease pathogenesis and progression. (
  • Autonomic neuropathy includes both parasympathetic and sympathetic dysfunction. (
  • The etiology of autonomic dysfunction can be primary or idiopathic and secondary causes. (
  • In addition, autonomic dysfunction is associated with various medications. (
  • emg/ncv diagnosed sensory & motor demylinating neuropathy, can that cause: bladder dysfunction/retention, autonomic & vasovagal dysfunction? (
  • Can it cause bladder dysfunction/autonomic % Vasvovagal problems. (
  • Cardiac autonomic dysfunction, assessed by reduced heart rate variability, correlated with sudomotor denervation. (
  • Evaluation of cardiovascular autonomic dysfunction according to heart rate turbulence and variability in patients with relapsing remitting multiple sclerosis. (
  • The aim of this study was to evaluate the presence of cardiovascular autonomic dysfunction using HRT and HRV parameters determined via 24-hour Holter ECG monitorin. (
  • Familial dysautonomia (FD) is an autosomal recessive disorder characterized by autonomic and sensory dysfunction. (
  • The FD neuropathology results in variable degrees of sensory and autonomic dysfunction affecting most of the organ body systems. (
  • Patients with PD and sensory or autonomic dysfunction may find these disturbances contributing to motor dysfunction, said Dr. Weinstock, who treats patients with PD and a variety of complex medical conditions in his private practice. (
  • Autonomic dysfunction can be an underappreciated feature of PD, but such manifestations as orthostatic hypotension and poor thermal regulation can have significant negative impact on quality of life for an individual with PD. (
  • So it's a real delight today to be able to provide an overview of autonomic dysfunction in Parkinson's disease, which is a subject near and dear to my heart. (
  • These so-called nonmotor features include abnormalities of sensation, behavioral changes, sleep disorders, fatigue, and for our purposes today, autonomic dysfunction. (
  • Virtually the entire array of autonomic function can be and is impaired in individuals with Parkinson's disease, including cardiovascular, gastrointestinal, urinary, sexual, and thermoregulatory dysfunction. (
  • Over a decade ago now, we surveyed our clinic patients using a simple, non-validated questionnaire and found that when one looked at the various aspects of autonomic dysfunction, virtually in every instance, individuals with Parkinson's disease described more symptoms of autonomic dysfunction than did controls, who were primarily spouses. (
  • Diabetic autonomic neuropathy (DAN) may impact the BM, because the sympathetic nervous system is prominently involved in BM stem cell trafficking. (
  • In conclusion, autonomic neuropathy in the BM impairs stem cell mobilization in diabetes with dysregulation of the life-span regulators p66Shc and Sirt1 . (
  • Diabetic patients often experience autonomic neuropathy, which is characterized by pauperization of SNS fibers in multiple organs ( 18 - 20 ). (
  • Thus, we herein hypothesize that diabetic autonomic neuropathy (DAN) can affect BM function and stem cell mobilization. (
  • Starting from the observation that patients with DAN have a marked pauperization of peripheral blood (PB) CD34 + cells, we used several experimental models and conditions to demonstrate that autonomic neuropathy in the BM is causally linked to impaired stem cell mobilization in diabetes, which is associated with defective reperfusion after ischemia. (
  • To define the nature of micturition disturbance in patients with acute idiopathic autonomic neuropathy (AIAN). (
  • Acute idiopathic autonomic neuropathy (AIAN), 1, 2 or pure pandysautonomia, is a rare but distinct clinical entity first described by Young et al in 1969. (
  • Diabetic autonomic neuropathy is associated with an increased mortality ( 1 - 3 ). (
  • To clarify the relationship between autonomic neuropathy and cardiovascular morbidity and mortality, it is important to evaluate both parasympathetic and sympathetic nerve functions. (
  • In addition to the acquired causes, inherited disorders like hereditary sensory-autonomic neuropathy (HSAN), familial amyloid polyneuropathy (FAP), Tangier disease, and Fabry disease also exist. (
  • HealthDay News) - Sudomotor denervation has been demonstrated in individuals with diabetic neuropathy, and the sweat gland innervation index (SGII) correlates with glycated hemoglobin (HbA1c) levels, according to research published online Feb. 1 in Diabetes Care . (
  • The researchers found that patients with diabetic neuropathy exhibited sudomotor denervation, manifested as depleted periglandular nerve fibers with lower SGII compared with control subjects. (
  • In subjects with diabetic autonomic neuropathy (DAN), distal left ventricular (LV) denervation contrasts with preservation of islands of proximal innervation, which exhibit impaired vascular responsiveness. (
  • Studies that evaluated mortality and morbidity in patients with diabetes mellitus and cardiovascular autonomic neuropathy (CAN) from 2001 onward. (
  • Diabetic autonomic neuropathy, particularly cardiac autonomic neuropathy, is considered an important potential factor involved in the disruption of circadian cardiovascular rhythms [ 10 ]. (
  • The review summarises the battery of non-invasive autonomic function tests available for diabetic autonomic neuropathy diagnosis as well as cross-sectional and follow-up studies supporting their importance in risk stratification for diabetic micro-vascular complications and cardiovascular morbidity/mortality. (
  • In 1973, the British Medical Journal and the Lancet published three articles on diabetic autonomic neuropathy [ 13 - 15 ], which would then be followed over the years by an unbroken series of studies and publications. (
  • The implications are discussed, with particular reference to the association between autonomic neuropathy and the primary glaucomas. (
  • He (14-19) along with Alcántara (20), suggested that Chagas' disease is a neuropathy resulting from denervation caused by widespread destruction of parasympathetic neurons and nervous fibers in different areas - a theory that explained the occurrence of cardiopathy and megaviscera. (
  • Also we performed CC-EMG in order to evaluate penile autonomic neuropathy. (
  • Cavernous smooth muscle electromyography showed asynchronous and asymetric potentials in G1 (minimal autonomic neuropathy) and denervation potentials in G2 characteristic of severe CC damage. (
  • It is classified as a hereditary sensory and autonomic neuropathy (HSAN type III), and is also known as Riley-Day syndrome, which was named for the two doctors who first described it in 1949. (
  • The hyperhidrosis appears, despite the reduction of sudomotor fibers and sweat glands associated with this autonomic neuropathy. (
  • ENGLISH ABSTRACT: Background: Atrial fibrillation (AF) is associated with increased cardiovascular morbidity and mortality, but it is uncertain if catheter-based renal denervation (RD) can reduce AF in patients with hypertensive heart disease (HHD). (
  • The Epicardial Ablation for Atrial Fibrillation live webcast will feature a panel discussion of a minimally invasive pulmonary vein isolation and partial autonomic denervation procedure for the surgical ablation of atrial fibrillation (AF) performed at THE HEART HOSPITAL Baylor Plano. (
  • Although paroxysmal atrial fibrillation (AF) is known to be initiated by rapid firing of pulmonary veins (PV) and non-PV triggers, the crucial role of cardiac autonomic nervous system (ANS) in the initiation and maintenance of AF has long been appreciated in both experimental and clinical studies. (
  • In parallel, the crucial role of cardiac autonomic nervous system (ANS) in the initiation and maintenance of atrial fibrillation (AF), especially paroxysmal AF, has long been appreciated in both experimental and clinical studies [ 3 - 8 ]. (
  • AimsThis study examined the difference in autonomic modification (AM) and its effect on paroxysmal atrial fibrillation (PAF) recurrence between segmental pulmonary vein isolation (S-PVI) and circumferential PVI (C-PVI).Methods and resultsSuccessful S-PVI or C-PVI with a basket catheter was achieved in 120 consecutive PAF patients. (
  • The effect of modulation of the autonomic nervous system by RDN on atrial electrophysiology and ventricular rate control during atrial fibrillation (AF) is unknown. (
  • The aim of our study was to investigate the roles of renal sympathetic nerve stimulation ( RSS ) on atrial fibrillation and cardiac autonomic nervous activity. (
  • Conclusions This study demonstrated that renal sympathetic nerve activation induced by 3 hours of P‐ RSS facilitated atrial fibrillation inducibility by upregulating cardiac autonomic nervous activity, suggesting a potential autonomic cross talk between kidney and heart. (
  • I-123-Metaiodobenzylguanidine imaging in patients with atrial fibrillation undergoing cardiac mapping and ablation of autonomic ganglia. (

  • Briefly, autonomic dysreflexia develops in individuals with a neurologic level of spinal cord injury at or above the sixth thoracic vertebral level (T6). (
  • Autonomic dysreflexia causes an imbalanced reflex sympathetic discharge, leading to potentially life-threatening hypertension. (
  • Complications associated with autonomic dysreflexia result directly from sustained, severe peripheral hypertension. (
  • I have only experienced autonomic dysreflexia twice since he took me off of the bladder spasm medication. (
  • Autonomic dysreflexia (AD) is a life-threatening condition prevalent amongst patients with high spinal cord injury (SCI) and may occur any time after injury. (

  • Regarding the ACE polymorphism, animals harboring 3 copies of the ACE gene, which is accompanied by increased synthesis of Ang II, demonstrated left ventricular hypertrophy, higher pressure values, overt proteinuria, and risk of nephropathy, which is probably associated with autonomic imbalance ( 9 - 11 ). (
  • Our data show that denervation in the diabetic BM is mediated by the 66-kDa protein from the src homology and collagen homology domain ( p66Shc ) and that impaired mobilization relies on sirtuin 1 ( Sirt1 ) dysregulation, both of which are therefore potential targets to restore BM cell-mediated vascular repair. (
  • The present study aimed to investigate cardiovascular autonomic modulation and angiotensin II (Ang II) activity in diabetic mice that were genetically engineered to harbor two or three copies of the angiotensin-converting enzyme gene. (
  • Data indicates that a small increase in angiotensin-converting enzyme activity in diabetic animals leads to greater impairment of autonomic function, as demonstrated by increased sympathetic modulation and reduced cardiac vagal modulation along with increased renal expression of Ang II. (

  • 6, 7 Variant forms may also occur, 5 in which sensory fibres are involved 8, 9 or cholinergic autonomic fibres alone are affected. (
  • These results suggest a direct effect of angiotensin II on autonomic ganglia, which can contribute to the pressor effects of angiotensin II through sympathetic activation. (
  • The other pillar, the scenario of parasympathetic neuron loss in parallel with 'relative sympathetic hyperactivity', was to be called into question by the anatomopathological findings of Alcántara himself, who in 1970 published his observations of denervation in intramural ganglia of the heart and cervicothoracic ganglia due to Chagas' disease (24).

(
  • The effects of autonomic innervation of tumors on tumor growth remain unclear. (
  • Here we developed a series of genetic techniques to manipulate autonomic innervation in a tumor- and fiber-type-specific manner in mice with human breast cancer xenografts and in rats with chemically induced breast tumors. (
  • These findings suggest that autonomic innervation of tumors regulates breast cancer progression. (
