Low rectal cancer: abdominoperineal resection or low Hartmann resection? A postoperative outcome analysis.
2011
BACKGROUND In distal rectum cancers, when the sphincters are not affected and it is not possible to perform a coloanal anastomosis because of the presence of comorbidities or the advanced age of the patient, a low Hartmann resection with total mesorectal excision can be performed. Low Hartmann resection is usually considered to be a shorter procedure and to have an inferior morbidity compared with abdominoperineal resection of the rectum. OBJECTIVE This study aimed to compare the postoperative outcome of a series of patients with low rectal cancer who have undergone either low Hartmann resection or abdominoperineal resection. DESIGN This study is a retrospective analysis of data collected i…
Serotonergic modulation of response inhibition and re-engagement? Results of a study in healthy human volunteers
2010
Objective Cognitive functions dependent on the prefrontal cortex, such as the ability to suppress behavior (response inhibition) and initiate a new one (response re-engagement) is important in the activities of daily life. Central serotonin (5-HT) function is thought to be a critical component of these cognitive functions. In recent studies, 5-HT failed to affect stop-signal reaction time (SSRT), a fundamental process in behavioral inhibition. We were interested if response inhibition and re-engagement are influenced through central 5-HT activity as mediated via the 5-HT transporter. Methods Here, using a stop-change task, we investigated the effects of acute and repeated treatment with 10 …
Distribution of liver disease in a cohort of immigrants in Sicily: analysis of day-hospital admissions in a migration medicine unit.
2014
The objective of this study was to evaluate the frequency of liver disease and its aetiology in a cohort of immigrants. We retrospectively examined the hospital discharge charts of all the immigrant patients presenting at our day hospital from July 2009 to June 2013, and after evaluating the anamnestic, clinical and laboratory data on these charts we identified subjects with liver disease and its various aetiologies. The total sample population consisted of 1218 patients, of whom 112 (9.2%) had a diagnosis of liver disease. More than two-thirds of the latter (67.8%) came from Africa, while 15.2% were from Asia and 17.0% from Eastern Europe. In most patients the disease was related to HBV (4…
Melperone is an Inhibitor of the CYP2D6 Catalyzed O-demethylation of Venlafaxine
2003
INTRODUCTION Melperone, a butyrophenone neuroleptic, is frequently used for its sleep-inducing properties. Despite its common use for more than 30 years, it is not yet characterized regarding its effects on cytochrome P450 s (CYPs). In an open pilot study, effects of melperone on the steady-state blood levels of venlafaxine, a recently introduced serotonin- and noradrenaline reuptake inhibiting antidepressant, were assessed. METHODS The dose-corrected serum concentrations of venlafaxine and O-desmethylvenlafaxine were analyzed retrospectively in a therapeutic drug-monitoring (TDM) database comprising 94 patients. In addition, three patients received venlafaxine and melperone concomitantly a…
Perceived coercion to enter treatment among involuntarily and voluntarily admitted patients with substance use disorders
2016
Background Perceived coercion is a sense of pressure related to the experience of being referred to treatment. The sense of pressure arises from the patient’s internal perception of coercion. The sources of coercion may be the legal system, the family, the health system, or self-criticism (internal sources). Here, we studied patients diagnosed with substance use disorders that were involuntarily admitted to hospital, pursuant to a social services act. We sought to determine whether these patients perceived coercion differently than patients that were admitted voluntarily. Methods This study included patients admitted to combined substance use disorder and psychiatry wards in three publicly …
The dynamics of radical right-wing populist party preferences and perceived group threat: A comparative panel analysis of three competing hypotheses …
2014
Existing cross-sectional research considers citizens' preferences for radical right-wing populist (RRP) parties to be centrally driven by their perception that immigrants threaten the well-being of the national ingroup. However, longitudinal evidence for this relationship is largely missing. To remedy this gap in the literature, we developed three competing hypotheses to investigate: (a) whether perceived group threat is temporally prior to RRP party preferences, (b) whether RRP party preferences are temporally prior to perceived group threat, or (c) whether the relation between perceived group threat and RRP party preferences is bidirectional. Based on multiwave panel data from the Netherl…
Acute Physiological Responses to Four Running Sessions Performed at Different Intensity Zones
2020
AbstractThis study investigated acute responses and post 24-h recovery to four running sessions performed at different intensity zones by supine heart rate variability, countermovement jump, and a submaximal running test. A total of 24 recreationally endurance-trained male subjects performed 90 min low-intensity (LIT), 30 min moderate-intensity (MOD), 6×3 min high-intensity interval (HIIT) and 10×30 s supramaximal-intensity interval (SMIT) exercises on a treadmill. Heart rate variability decreased acutely after all sessions, and the decrease was greater after MOD compared to LIT and SMIT (p<0.001; p<0.01) and HIIT compared to LIT (p<0.01). Countermovement jump decreased only after …
Establishing cut-points for physical activity classification using triaxial accelerometer in middle-aged recreational marathoners
2018
The purpose of this study was to establish GENEA (Gravity Estimator of Normal Everyday Activity) cut-points for discriminating between six relative-intensity activity levels in middle-aged recreational marathoners. Nighty-eight (83 males and 15 females) recreational marathoners, aged 30-45 years, completed a cardiopulmonary exercise test running on a treadmill while wearing a GENEA accelerometer on their non-dominant wrist. The breath-by-breath V̇O2 data was also collected for criterion measure of physical activity categories (sedentary, light, moderate, vigorous, very vigorous and extremely vigorous). GENEA cut-points for physical activity classification was performed via Receiver Operatin…
Topical prazosin attenuates sensitivity to tactile stimuli in patients with complex regional pain syndrome
2015
Background The sympathetic nervous system may play an important role in certain forms of chronic pain. The main aim of this study was to determine whether functional blockade of α1-adrenoceptors would alter sensitivity to cutaneous stimulation in patients with complex regional pain syndrome (CRPS). Methods and Results In an initial study, high-performance liquid chromatography-mass spectrometry of intradermal interstitial fluid collected from the forearms of three healthy individuals established that the α1-adrenoceptor antagonist prazosin penetrated the skin barrier when mixed in Lipoderm® cream base. Next, we found that application of this cream to the forearm of 10 healthy participants a…
Diabetic Microagiopathy of Oral Mucosa Depends on Disease Duration and Therapy
2017
Background: Diabetes mellitus is a chronic degenerative systemic disease whose prevalence is increasing. This paper aims to evaluate the effects of diabetic microangiopathy, depending on its duration and the type of treatment administered, by using polarized light videocapillaroscopy of the oral mucosa. Material/Methods: We enrolled 120 subjects: 60 healthy subjects and 60 patients with diabetes mellitus. In turn, patients were divided into 3 subgroups according to the type of diabetes, the duration of the disease, and the type of treatment administered. A videocapillaroscopic examination of the oral mucosa was carried out on the diabetic and healthy subjects. Results: Changes in microcircu…
