Effects of mindfulness and distraction on pain depend on individual differences in pain catastrophizing: an experimental study
BackgroundThe aim of this study was to investigate whether the perception of experimental pain was different during a mindfulness manipulation than during a distraction manipulation. Furthermore, it was examined if effects were moderated by dispositional pain catastrophizing.
MethodsUndergraduate students (n=51) completed self-report measures of pain catastrophizing and mindfulness. Subsequently, they were administered a series of mildly painful heat stimuli, which they had to rate. During pain induction, participants listened to either a pre-recorded mindfulness instruction (mindfulness group) or a pre-recorded story (distraction group).
ResultsAfter controlling for baseline experimental pain ratings, we found no overall group effect, indicating that there was no difference in experienced pain between the mindfulness group and the distraction group. However, a significant moderation effect was found. When dispositional pain catastrophizing was high, pain was less pronounced in the mindfulness group than in the distraction group, whereas the opposite effect was found when the level of pain catastrophizing was low.
ConclusionsThe findings suggest that in persons with a high level of catastrophic thinking about pain, mindfulness-based coping may be a better approach than distraction
Effects of training and albuterol on pain and fatigue in facioscapulohumeral muscular dystrophy

51802.pdf (publisher's version ) (Closed access)BACKGROUND : We recently reported a randomised controlled trial on the efficacy of strength training and the beta2-adrenergic agonist albuterol in patients with facioscapulohumeral muscular dystrophy (FSHD). Strength training and albuterol appeared safe interventions with limited positive effect on muscle strength and volume. We concurrently explored the prevalence and the characteristics of pain and fatigue in the participating FSHD patients, because these are probably underreported but clinically relevant symptoms in this disorder. Next, we studied the effects of albuterol and strength training on pain, experienced fatigue, health-related functional status and psychological distress. METHODS : Sixty-five patients were randomised to strength training of elbow flexors and ankle dorsiflexors or non-training. After 26 weeks, albuterol (sustained-release, 8 mg bid) was added in a randomised, double-blind, placebo-controlled design. Outcomes comprised self-reported pain, experienced fatigue, functional status and psychological distress obtained with validated questionnaires at 52 weeks. RESULTS : Eighty percent of patients reported chronic persistent or periodic, multifocal pains. Thirty-four percent of the participants were severely fatigued. Strength training and albuterol failed to have a significant effect on all outcomes. CONCLUSIONS : Pain and fatigue are important features in FSHD. Strength training and albuterol do not have a positive or negative effect on pain, experienced fatigue, functional status and psychological distress
Results from the translation and adaptation of the Iranian Short-Form McGill Pain Questionnaire (I-SF-MPQ): preliminary evidence of its reliability, construct validity and sensitivity in an Iranian pain population
<p>Abstract</p> <p>Background</p> <p>The Short Form McGill Pain Questionnaire (SF-MPQ) is one of the most widely used instruments to assess pain. The aim of this study was to translate and culturally adapt the questionnaire for Farsi (the official language of Iran) speakers in order to test its reliability and sensitivity.</p> <p>Methods</p> <p>We followed Guillemin's guidelines for cross-cultural adaption of health-related measures, which include forward-backward translations, expert committee meetings, and face validity testing in a pilot group. Subsequently, the questionnaire was administered to a sample of 100 diverse chronic pain patients attending a tertiary pain and rehabilitation clinic. In order to evaluate test-retest reliability, patients completed the questionnaire in the morning and early evening of their first visit. Finally, patients were asked to complete the questionnaire for the third time after completing a standardized treatment protocol three weeks later. Intraclass correlation coefficient (ICC) was used to evaluate reliability. We used principle component analysis to assess construct validity.</p> <p>Results</p> <p>Ninety-two subjects completed the questionnaire both in the morning and in the evening of the first visit (test-retest reliability), and after three weeks (sensitivity to change). Eight patients who did not finish treatment protocol were excluded from the study. Internal consistency was found by Cronbach's alpha to be 0.951, 0.832 and 0.840 for sensory, affective and total scores respectively. ICC resulted in 0.906 for sensory, 0.712 for affective and 0.912 for total pain score. Item to subscale score correlations supported the convergent validity of each item to its hypothesized subscale. Correlations were observed to range from r<sup>2 </sup>= 0.202 to r<sup>2 </sup>= 0.739. Sensitivity or responsiveness was evaluated by pair t-test, which exhibited a significant difference between pre- and post-treatment scores (p < 0.001).</p> <p>Conclusion</p> <p>The results of this study indicate that the Iranian version of the SF-MPQ is a reliable questionnaire and responsive to changes in the subscale and total pain scores in Persian chronic pain patients over time.</p
High disease impact of myotonic dystrophy type 2 on physical and mental functioning
The aim of the study was to investigate health status in patients with myotonic dystrophy type 2 (DM2) and determine its relationship to pain and fatigue. Data on health status (SF-36), pain (MPQ) and fatigue (CIS-fatigue) were collected for the Dutch DM2 population (n = 32). Results were compared with those of sex- and age-matched adult-onset myotonic dystrophy type 1 (DM1) patients. In addition, we compared the obtained scores on health status of the DM2 group with normative data of the Dutch general population (n = 1742). Compared to DM1, the SF-36 score for bodily pain was significantly (p = 0.04) lower in DM2, indicating more body pain in DM2. DM2 did not differ from DM1 on any other SF-36 scales. In comparison to the Dutch population, DM2 patients reported lower scores (indicating worse clinical condition) on the physical functioning, role functioning-physical, bodily pain, general health, vitality, social functioning, and role functioning-emotional scales (p < 0.01 on all scales). The difference was most profound for the physical functioning scale. In the DM2 group the severity of pain was significantly correlated with SF-36 scores for bodily pain (p = 0.003). Fatigue was significantly correlated with the SF-36 scores for role functioning-physical (p = 0.001), general health (p = 0.02), and vitality (p = 0.02). The impact of DM2 on a patients’ physical, psychological and social functioning is significant and as high as in adult-onset DM1 patients. From the perspective of health-related quality of life, DM2 should not be considered a benign disease. Management of DM2 patients should include screening for pain and fatigue. Symptomatic treatment of pain and fatigue may decrease disease impact and help improve health status in DM2, even if the disease itself cannot be treated

Food discards : nature, reasons for discard, and relationship to household variables
A sample of 243 Willamette Valley households participated in
personal interviews and kept 7-day records of all foods brought into
the household but not consumed by human household members. Their
reason for discarding the foods, the amounts of discard, and their
assessment of the safety of the foods were compared to household
characteristics. Age of the major food preparer and the presence of
children had a marked effect upon the discard patterns of the household.
Households with children younger than 10 years discarded an
average of 4.36
(2743 g), and childless households discarded an average of $2.11
(1195 g).
In a sample of 50 households, as the household refrigerator
temperature (as determined during the personal interview) increased
from 35°F (2°C) to 68°F (20°C), the amount of discards also increased
(r [subscript cost] = .82, r [subscript g] = .80).
Food which was being discarded due to poor quality or because it
was judged unsafe to eat by the householder was collected daily over
a 3-day period for a subsample of 50 of the households. These
collected discards were evaluated by a trained panel for degree of
off-color, off-odor, and off-texture compared to the normal product
standards, and also were microbiologically analyzed.
When the householder's estimate of amount of food discarded was
converted from their household measures to grams using food composition
tables, the householder's estimate was 97% of the actual grams
of food as weighed in the laboratory.
Both studies found consumer confusion between solely quality
changes in a food and environmental conditions that allow the possibility
of pathogen growth in foods. In 62% of the microbiologically
analyzed foods, the householder did not make correct safety assessments.
In 9% of the microbiologically analyzed foods, an assessment
of safe was made by the householder for foods which were determined
to be at risk. Uncoded dates on packaged foods were the basis for
the householder's discard decision for 17% of the total foods
appearing on the 7-day records. Householders often stated they felt
it would be unsafe to consume this food. Educational programs which
give the householder criteria for the evaluation of food safety are
recommended
