Reduced Risk of Reoperations With Modern Deep Brain Stimulator Systems: Big Data Analysis From a United States Claims Database
2021
Objective: There have been significant improvements in the design and manufacturing of deep brain stimulation (DBS) systems, but no study has considered the impact of modern systems on complications. We sought to compare the relative occurrence of reoperations after de novo implantation of modern and traditional DBS systems in patients with Parkinson's disease (PD) or essential tremor (ET) in the United States.Design: Retrospective, contemporaneous cohort study.Setting: Multicenter data from the United States Centers for Medicare and Medicaid Services administrative claims database between 2016 and 2018.Participants: This population-based sample consisted of 5,998 patients implanted with a …
Effects of Group Psychotherapy, Individual Counseling, Methylphenidate, and Placebo in the Treatment of Adult Attention-Deficit/Hyperactivity Disorder
2015
Importance Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder with high prevalence in adulthood. There is a recognized need to assess the efficacy of psychotherapy in adult ADHD. Objective To evaluate the efficacy of cognitive behavioral group psychotherapy (GPT) compared with individual clinical management (CM) and that of methylphenidate hydrochloride compared with placebo. Design, Setting, and Participants Prospective, multicenter, randomized clinical trial of 18- to 58-year-old outpatients with ADHD from 7 German study centers. Patients were recruited between January 2007 and August 2010, treatment was finalized in August 2011, and final follow-up assessmen…
Eine vergleichende Untersuchung zum Reizdarmsyndrom bei konsekutiven Patienten zweier internistischer Ambulanzen
2001
OBJECTIVES We investigated the nature of illness behavior and the meaning of emotional deficiencies during childhood in patients with irritable bowel diseases (IBS). DATA A consecutive study in two tertiary referral centers was conducted with 48 patients suffering from irritable bowel diseases (IBS) and 91 patients with inflammatory bowel disease (IBD). METHODS The diagnosis of IBS was made by following the Manning criteria, a positive diagnosis of IBD was established through physical, endoscopic and radiologic examinations and was confirmed histologically. Psychological data were obtained by structured psychiatric interviews and psychological self-report measures (GBB). RESULTS We found th…
Enhanced inhibitory control during re-engagement processing in badminton athletes : An event-related potential study
2019
Highlights • Reaction time and event-related potentials of inhibitory control were compared in badminton experts and nonathletes. • Badminton experts showed enhanced inhibitory control and more efficient neural mechanisms. • Badminton experts performed better inhibitory control processing in re-engagement. • The re-engagement processing better demonstrated altered brain activity in badminton experts.
Treating Sleep Disorders with an ACT-Based Behavior Change Support System
2017
Suitable duration and appropriate quality of sleep are essential for mental and cognitive wellbeing. Sleep disorders, whether mild or severe, have proven to have adverse effects on general wellbeing. One's quality of life could be disturbed as a consequence of various mental conditions, sleep disorders being one of them. Researchers have started paying attention to designing, implementing and evaluating eHealth interventions to address sleep disorders. In this chapter, we highlight findings from a field study that was conducted to evaluate effect of software features on a Web-based intervention for sleep disorders. Tyyne is a Web-based eHealth intervention that will be repeatedly mentioned …
Pheromones linked to sexual behaviors excite the appetitive phase of feeding behavior of Aplysia fasciata . I. Modulation and excitation of appetitiv…
1998
Pheromones presumably secreted by mating conspecifics – as well as homogenates containing tissue that is homologous with the atrial gland – increase the time that Aplysia fasciata spend feeding. This effect is caused by increasing the number of feeding episodes initiated in response to food, whereas the duration of a feeding bout remains unchanged. The increase in the number of feeding episodes is related to increases in head waving and crawling, i.e., appetitive movements that bring the animal into contact with food, as well as an increase in the responsiveness to food after it is contacted. Releasing a homogenate containing atrial gland tissue, or egg laying hormone, in the water near the…
The effects of electrodermal lability and stimulus intensity on skin conductance habituation: A preliminary report
1981
A between-subjects design (N=60) was used to investigate the effects of electrodermal lability and auditory stimulus intensity on habituation of the skin conductance response (SCR). Subjects were subdivided into “labile” and “stabile” groups on the basis of frequency of nonspecific electrodermal responses during the prestimulation period. They received 20 presentations of a 1,000-Hz tone of 15, 35, 55, 75, 95, or 110 dB. There were significant effects of stimulus intensity on all three habituation measures (number of trials to habituation, reciprocal of SCR frequency to the first 10 stimuli, slope of the regression of SCR amplitude on log stimulus number). Additionally, significant effects …
Electrical responses of homing pigeon and guinea pig Purkinje cells to pineal indoleamines applied by microelectrophoresis
1984
The effects of microelectrophoretically applied melatonin (aMT), 5-methoxytryptophol (ML), 5-hydroxytryptophol (HL) and noradrenaline (NA) on the electrical activity of cerebellar Purkinje and other cells during both day- and nighttime were studied in urethane-anesthetized intact and pinealectomized homing pigeons and guinea pigs.
Pheromones linked to sexual behaviors excite the appetitive phase of feeding behavior of Aplysia fasciata II. Excitation of C-PR, a neuron involved i…
1998
Pheromones presumably released by conspecifics amplify both the appetitive and the consummatory components of feeding in Aplysia. These effects can be mimicked by administering homogenate of the large hermaphroditic duct containing atrial gland tissue, as well as peptides from the bag cells. Identified cerebro-pedal regulator (C-PR) neuron is thought to command various behaviors that comprise the appetitive phase of feeding. In a reduced preparation, we investigated the effects on the C-PR of applying these substances to the rhinophores, the sensory organs which detect pheromones. Stimuli that excite feeding in the animal were also found to affect the C-PR. Large hermaphroditic duct homogen…
The metabolic syndrome in hypertension: European society of hypertension position statement.
2008
The metabolic syndrome considerably increases the risk of cardiovascular and renal events in hypertension. It has been associated with a wide range of classical and new cardiovascular risk factors as well as with early signs of subclinical cardiovascular and renal damage. Obesity and insulin resistance, beside a constellation of independent factors, which include molecules of hepatic, vascular, and immunologic origin with proinflammatory properties, have been implicated in the pathogenesis. The close relationships among the different components of the syndrome and their associated disturbances make it difficult to understand what the underlying causes and consequences are. At each of these …
