The role of tapentadol as a strong opioid in cancer pain management: a systematic and critical review

2017

The aim of this review was to assess the role of tapentadol given at medium-high doses in opioid-tolerant patients for cancer pain management in place of step-3 analgesics.A systematic literature search was performed out of which six studies and one secondary analysis provided data regarding tapentadol used as a step-3 analgesic for this review. Tapentadol, when used at ≥60 mg of oral morphine equivalents in opioid-tolerant patients with cancer pain, or passing from step-2 doses to ≥60 mg of oral morphine equivalents, was well tolerated and effective and could be considered as a flexible drug to be used for the management of moderate-to-severe cancer pain. The limited occurrence of gastroin…

Breakdown of choline-containing phospholipids in rat brain during severe weight loss.

2002

Recent investigations in human anorectic patients indicated changes of brain choline metabolism. We used starved rats to investigate possible changes of brain choline metabolites during severe weight loss. Reductions of body weight by 15, 30 and 45% resulted in significant decreases of cerebral phosphatidylcholine and sphingomyelin levels. Concomitantly, the brain tissue content of glycerophosphocholine was increased while phosphocholine and free choline were unchanged. We conclude that severe weight loss is accompanied by phospholipase activation and breakdown of choline-containing phospholipids in the brain.

Impact of a social media exercise service on individuals and employees

2016

Summary Study aim: The purpose of the present study was to investigate the impact of a social media exercise platform (HeiaHeia, Helsinki, Finland) on the level of physical activity, physical fitness, wellbeing and body weight of the service users. Material and methods: The subject group consisted of 2862 individuals who voluntarily participated in a web survey. Their age, gender, body mass index, physical fitness level and activity information were self-reported. Results: Most of the service users (78.1%) exercised more than three times a week. About 75% of the users reported that they were in good or excellent physical fitness, while about 50% were overweight. More than half (64.6%) of th…

Cardiorespiratory Coordination after Training and Detraining. A Principal Component Analysis Approach

2016

Our purpose was to study the effects of different training modalities and detraining on cardiorespiratory coordination (CRC). Thirty-two young males were randomly assigned to four training groups: aerobic (AT), resistance (RT), aerobic plus resistance (AT + RT), and control (C). They were assessed before training, after training (6 weeks) and after detraining (3 weeks) by means of a graded maximal test. A principal component (PC) analysis of selected cardiovascular and cardiorespiratory variables was performed to evaluate CRC. The first PC (PC1) coefficient of congruence in the three conditions (before training, after training and after detraining) was compared between groups. Two PCs were …

Ethanol inhibits astroglial cell proliferation by disruption of phospholipase D-mediated signaling.

2002

The activation of phospholipase D (PLD) is a common response to mitogenic stimuli in various cell types. As PLD-mediated signaling is known to be disrupted in the presence of ethanol, we tested whether PLD is involved in the ethanol-induced inhibition of cell proliferation in rat cortical primary astrocytes. Readdition of fetal calf serum (FCS) to serum-deprived astroglial cultures caused a rapid, threefold increase of PLD activity and a strong mitogenic response; both effects were dependent on tyrosine kinases but not on protein kinase C. Ethanol (0.1-2%) suppressed the FCS-induced, PLD-mediated formation of phosphatidic acid (PA) as well as astroglial cell proliferation in a concentration…

Independent component analysis on the mismatch negativity in an uninterrupted sound paradigm.

2008

We compared the efficiency of the independent component analysis (ICA) decomposition procedure against the difference wave (DW) and optimal digital filtering (ODF) procedures in the analysis of the mismatch negativity (MMN). The comparison was made in a group of 54 children aged 8-16 years. The MMN was elicited in a passive oddball protocol presenting uninterrupted auditory stimulation consisting of two frequent alternating tones (600 and 800 Hz) of 100 ms duration each. Infrequently, one of the 600 Hz tones was shortened to 50 or 30 ms. The event related potentials (ERPs) were decomposed into the MMN-like and non-MMN-like independent components (ICs) through the FastICA algorithm. The ICA …

Consensus Guidelines for Therapeutic Drug Monitoring in Neuropsychopharmacology: Update 2017

2017

AbstractTherapeutic drug monitoring (TDM) is the quantification and interpretation of drug concentrations in blood to optimize pharmacotherapy. It considers the interindividual variability of pharmacokinetics and thus enables personalized pharmacotherapy. In psychiatry and neurology, patient populations that may particularly benefit from TDM are children and adolescents, pregnant women, elderly patients, individuals with intellectual disabilities, patients with substance abuse disorders, forensic psychiatric patients or patients with known or suspected pharmacokinetic abnormalities. Non-response at therapeutic doses, uncertain drug adherence, suboptimal tolerability, or pharmacokinetic drug…

Distribution and course of cortico-respiratory projections for voluntary activation in man

2002

The function and course of the cortico-respiratory projections in man are not yet well established. In 30 normal volunteers respiratory muscles were activated by magnetic stimulation of the motor cortex and the cervical and thoracic spinal roots with bilateral recordings from the respiratory muscles. Following cortical stimulation contralateral responses were obtained in all subjects during voluntary inspiration showing a mean latency and amplitude of 13.4±1.4ms/1.6±1.2 mV (stimulation of the left hemisphere) and 13.2±1.3ms/2.5±2.5 mV (stimulation of the right hemisphere). Ipsilateral responses were obtained in only 18 (right side) and 21 (left side) subjects and had a significantly (p < 0.…

Process evaluation of a complex workplace intervention to prevent musculoskeletal pain in nursing staff: results from INTEVAL_Spain

2021

Abstract Background INTEVAL_Spain was a complex workplace intervention to prevent and manage musculoskeletal pain among nursing staff. Process evaluations can be especially useful for complex and multifaceted interventions through identifying the success or failure factors of an intervention to improve the intervention implementation. Objectives This study performed a process evaluation of INTEVAL_Spain and aimed to examine whether the intervention was conducted according to the protocol, to investigate the fulfilment of expectations and the satisfaction of workers. Methods The intervention was a two-armed cluster randomized controlled trial and lasted 1 year. The process evaluation include…
