Positive affect and self-control: attention to self-control demands mediates the influence of positive affect on consecutive self-control.
2013
Positive affect (PA) can either improve or impair self-control performance, depending on whether two tasks are dissimilar, and thus require flexible releasing and switching, or similar, which requires stable maintenance. The present study suggests that this effect is mediated by attentional shifts. The authors found that participants under PA, who performed on two dissimilar tasks and had to switch to a new response dimension, were less attentive to distracting information compared to neutral affect (NE), leading to better performance. In contrast, participants under PA who did not have to switch, were more attentive to distracting information compared to participants under NE. These findin…
Opioid plasma concentration during switching from morphine to methadone: Preliminary data
2003
Opioid switching is often used to improve the opioid response in cancer patients experiencing poor analgesia or adverse effects. However, no data are available on plasmatic changes of opioids and their metabolites during these phases, and whether there exists a relationship with the clinical events. In a prospective study of 10 consecutive cancer patients on oral morphine but with uncontrolled pain (greater >4 on a numerical scale of 0 to 10) and/or moderate to severe opioid adverse effects (on a level of 2 and 3 of a verbal scale) and not responsive to adjuvant medications, switching to oral methadone was performed using a fixed ratio of 5:1, leaving extra-doses of 1/5 of the daily dose of…
Plantar flexor activation capacity and H reflex in older adults: adaptations to strength training.
2002
The purpose of this study was to investigate whether the voluntary neural drive and the excitability of the reflex arc could be modulated by training, even in old age. To this aim, the effects of a 16-wk strengthening program on plantar flexor voluntary activation (VA) and on the maximum Hoffman reflex (Hmax)-to-maximum M wave (Mmax) ratio were investigated in 14 elderly men (65–80 yr). After training, isometric maximum voluntary contraction (MVC) increased by 18% ( P < 0.05) and weight-lifting ability by 24% ( P < 0.001). Twitch contraction time decreased by 8% ( P < 0.01), but no changes in half relaxation time and in peak twitch torque were observed. The VA, assessed by twitch …
Rapid Switching Between Transdermal Fentanyl and Methadone in Cancer Patients
2005
Purpose The aim of this study was to examine the clinical effects of switching from transdermal (TTS) fentanyl to methadone, or vice versa, in patients with a poor response to the previous opioid. Patients and Methods A prospective study was carried out on 31 patients who switched from TTS fentanyl to oral methadone, or vice versa, because of poor opioid response. A fixed conversion ratio of fentanyl to methadone of 1:20 was started and assisted by rescue doses of opioids, and then doses were changed according to clinical response. Pain and symptom intensity, expressed as distress score, were recorded before switching doses of the two opioids and after subsequent doses. The number of change…
Muscle fiber-type distribution predicts weight gain and unfavorable left ventricular geometry: a 19 year follow-up study
2006
Abstract Background Skeletal muscle consists of type-I (slow-twitch) and type-II (fast-twitch) fibers, with proportions highly variable between individuals and mostly determined by genetic factors. Cross-sectional studies have associated low percentage of type-I fibers (type-I%) with many cardiovascular risk factors. Methods We investigated whether baseline type-I% predicts left ventricular (LV) structure and function at 19-year follow-up, and if so, which are the strongest mediating factors. At baseline in 1984 muscle fiber-type distribution (by actomyosin ATPase staining) was studied in 63 healthy men (aged 32–58 years). The follow-up in 2003 included echocardiography, measurement of obes…
Paroxysmal atrial fibrillation and high degree AV block: use of single-lead VDDR pacing with mode switching.
1998
Dual chamber rate responsive pacing incorporating a mode switching option is increasingly used in patients with chronic paroxysmal atrial fibrillation and high degree AV block. Single-lead VDDR pacemakers have rarely used for this indication. The purpose of this study was to determine their reliability of atrial sensing during atrial fibrillation, the percentage of atrial synchronous ventricular pacing, and the behavior of the sinus rate outside the phases of atrial fibrillation. We studied ten patients with a single-lead VDDR pacemaker implanted for this indication. Follow-up visits were performed at predischarge and after 1, 3, 6, 12, 18, and 24 months. During the mean follow-up period of…
Switching from oxycodone to methadone in advanced cancer patients
2012
The aim of this study was to prospectively evaluate the outcomes and the conversion ratio of switching from oxycodone to methadone in advanced cancer patients admitted to an acute palliative care unit.A prospective study was carried out on a cohort of consecutive sample of patients receiving oxycodone, who were switched for different reasons mainly because of an inconvenient balance between analgesia and adverse effects. An initial conversion ratio between oxycodone and methadone was 3.3:1. Intensity of pain and symptoms associated with opioid therapy were recorded, and a distress score (DS) was also calculated as a sum of symptom intensity. A successful switching was considered when the in…
Outcome of opioid switching 4 weeks after discharge from a palliative care unit.
2011
Despite the favorable effects reported with opioid switching performed in a specialized unit in the short term, data on long-term basis are poor, particularly after discharging patients home or in other settings.The aim of this prospective study was to evaluate the long-term outcome of patients who were switched in an acute palliative care unit at a high volume of opioid switching. A consecutive sample of patients who underwent opioid substitution during admission in an acute palliative care unit were assessed for a period of 1 year. Patients were followed-up for 4 weeks after being discharged. Patients were contacted by phone or visited at the outpatient clinic 4 weeks after discharge. Epi…
Effects of 10 weeks of military training on neuromuscular function in non-overreached and overreached conscripts
2018
The purpose of the study was to examine how military training influences neuromuscular function in non-overreached and overreached conscripts. A total of 24 male conscripts participated in the study (8 weeks basic training + 2 weeks specialized training). All measurements were conducted during weeks 1, 5, 8 and 10. After the training period, non-overreached (NOR, n = 16) and overreached (OR, n = 8) groups were compared. Isometric maximal forces (bench press, elbow flexion and knee extension), single twitch (plantar flexors), H-reflex, M-wave (Hmax/Mmax) and V-wave (V/Mmax) (soleus) were measured. In knee extension, force production increased in NOR by 22.5 ± 20.5% (p 0.01) between weeks 1 …
Efficacy of switching between tumor necrosis factor-alfa inhibitors in psoriasis: results from the Italian Psocare registry
2014
Background: Some studies have shown that switching patients from one tumor necrosis factor (TNF)-alfa inhibitor to another may be beneficial when they have an inadequate response or an adverse event. Objective: We sought to assess the variables predicting the efficacy of the second TNF-alfa inhibitor in patients discontinuing the first TNF-alfa inhibitor. Methods: Data from all 5423 consecutive patients starting TNF-alfa inhibitor therapy for psoriasis between September 2005 and September 2010 who were included in the Italian Psocare registry were analyzed. Results: In 105 patients who switched to a second TNF-alfa inhibitor who had complete follow-up data, 75% improvement in the Psoriasis …
