Abstract
The objective of this study was to compare the scores of the Helplessness, Magnification, Rumination, and Catastrophizing factors of the Pain Catastrophizing Scale (PCS) between samples with different pain characteristics. The psychometric properties of the PCS were evaluated in 1,151 Brazilian adults (78.9% female; 38.6 (SD = 10.8) years): 335 had no pain, 390 had been in pain for less than 3 months, 250 had been in recurring pain for more than 3 months, and 176 had been in continuous pain for more than 3 months. Confirmatory factor analysis (CFA) was conducted to verify the fit of the PCS models. Convergent validity and reliability were evaluated. Multi-group analysis was used to estimate the invariance of the factorial model. The global score for the PCS factors was obtained using the regression weight matrix for estimating factor scores from CFA. Analysis of variance was used to compare scores between samples. After excluding three items, the tri-factorial model showed adequate fit. The model parameters were invariant (Δχ2(λ,i,β,Res); p≥0.05). Individuals experiencing pain showed higher scores for catastrophic thoughts. Individuals with pain for less than 3 months had the highest scores for Rumination (p < 0.001). The PCS showed valid, reliable, and invariant results for the sample of Brazilian adults in no pain or with different pain conditions. The PCS adequately discriminated individuals in pain from those without pain. Among those in pain, Rumination was the only discriminating factor.

Abstract
OBJECTIVES Patient compliance and satisfaction with analgesics prescribed after emergency department (ED) care for acute pain are poorly understood, largely because of the lack of direct patient follow-up with the ED provider. Our objective was to compare patient satisfaction with three analgesia regimens prescribed for post-ED care-a nasally administered nonsteroidal anti-inflammatory drug (NSAID), an opioid, or combination therapy-by collecting granular follow-up on analgesic use, pain scores, side effects, work activity levels, and overall satisfaction directly from patients. METHODS We designed a prospective registry linking ED assessment and analgesic management for acute pain of specific musculoskeletal or visceral etiologies with self-reported automated telephonic follow-up daily for the 4 days post-ED discharge. Patients were prescribed a specific NSAID (SPRIX, ketorolac tromethamine for nasal instillation) only, an oral opioid only, or both with the opioid clearly defined as rescue therapy, at the ED provider's discretion. RESULTS There were 824 evaluable subjects. Maximum pain scores improved day to day more effectively with a ketorolac-based approach. Self-reported rates of return to work and work effectiveness were higher with SPRIX than with opioids or combination therapy. Adverse effects of nausea, constipation, drowsiness, and abdominal pain were higher each day among patients taking an opioid; nasal irritation was more common with SPRIX. Overall satisfaction at the end of the follow-up period was higher with SPRIX-based treatment than with opioid monotherapy. CONCLUSIONS Automated telephonic follow-up of ED patients prescribed short-term analgesia is feasible. Ketorolac-based analgesia after an ED visit for many acute pain syndromes was associated with favorable patient outcomes and higher satisfaction than opioid-based therapy. SPRIX, an NSAID that is not available over the counter and has a novel delivery approach, may be useful for short-term post-ED outpatient analgesia.

Journal of clinical anesthesia. 2015;(1):33-8
Abstract
STUDY OBJECTIVE Oxytocin may play a role in pain modulation. The analgesic effects of breastfeeding with its associated endogenous oxytocin release have not been well investigated. To determine the impact of breastfeeding on incisional, perineal, and cramping pain after cesarean and vaginal delivery. DESIGN Institutional review board-approved prospective observational study. SETTING Labor and delivery and maternity wards. PATIENTS Healthy (American Society of Anesthesiology physical statuses 1 and 2) multiparous women who had cesarean (n = 40) and vaginal (n = 43) deliveries of singleton term infants and who were breastfeeding were enrolled. INTERVENTIONS Women completed diaries to record incisional, perineal, or cramping pain scores 5 minutes before, during, and 5 minutes after breastfeeding. MEASUREMENTS Demographic, obstetric, and neonatal variables, as well as analgesic use, were recorded. MAIN RESULTS There was no difference in incisional pain before, during, and after breastfeeding in women post-cesarean delivery. Cramping pain was significantly increased during, as compared with before or after breastfeeding in both the vaginal (P < .001) and cesarean (P < .001) delivery cohorts. CONCLUSIONS There was no analgesic effect on incisional pain during breastfeeding, indicating that endogenous oxytocin associated with breastfeeding may not play a significant role in postpartum cesarean wound pain modulation. Breastfeeding increased cramping pain after vaginal and cesarean delivery. The increase in cramping pain is most likely due to the breastfeeding-associated oxytocin surge increasing uterine tone.

Abstract
It is unknown whether nutritional status influences pain intensity in cancer patients receiving a transdermal fentanyl patch (FP). This study aimed to determine whether nutritional status is associated with pain intensity and to evaluate the influence of changes in nutritional status on pain intensity in cancer patients receiving transdermal FP treatment. We included 92 patients receiving transdermal FP treatment for the first time with switching from oxycodone. The patients were classified into low- and normal-nutrition groups based on their nutritional status, which was assessed according to the Nutrition Risk Screening 2002 (NRS 2002) parameters. The pain intensity of each patient was evaluated by a numeric rating scale (11-point scale from 0 to 10). NRS 2002 score and pain intensity were obtained on day 3 after the FP was applied to the skin. Pain intensities were significantly higher among patients in the low-nutrition group than among patients in the normal-nutrition group. NRS 2002 scores showed a significant positive correlation with the pain intensities. In 52 of 92 patients, who were evaluated using the NRS 2002 score and pain intensity on day 30 after FP application, the changes in NRS 2002 scores were significantly related to changes in pain intensities (odds ratio, 30.0; 95% confidence interval, 4.48-200.97; p=0.0005). These results suggest that an increase in the NRS 2002 score is a risk factor for an increase in pain intensity in cancer patients receiving FP treatment. Malnutrition may lead to poor pain management in cancer patients receiving FP treatment.
