Over the past 20 years, the Global Initiative for Asthma (GINA) has regularly published and annually updated a global strategy for asthma management and prevention that has formed the basis for many national guidelines. However, uptake of existing guidelines is poor. ⋯ This article provides a summary of key changes in the GINA report, and their rationale. The changes include a revised asthma definition; tools for assessing symptom control and risk factors for adverse outcomes; expanded indications for inhaled corticosteroid therapy; a framework for targeted treatment based on phenotype, modifiable risk factors, patient preference, and practical issues; optimisation of medication effectiveness by addressing inhaler technique and adherence; revised recommendations about written asthma action plans; diagnosis and initial treatment of the asthma-chronic obstructive pulmonary disease overlap syndrome; diagnosis in wheezing pre-school children; and updated strategies for adaptation and implementation of GINA recommendations.

The aim of this study was to investigate the impact of chronic pain on interpretation bias for ambiguous faces, using a recently developed paradigm with ecologically valid stimuli. ⋯ These results show clear evidence that chronic pain patients do demonstrate an interpretation bias towards painful faces and that this bias is greater for those who catastrophize more and have higher levels of fear of pain, but experienced less pain in the preceding week. Given the recent potential shown for interventions that modify cognitive biases, this paradigm would seem to be well suited to future efforts to modify interpretation biases in pain.

Combinations of analgesics with caffeine have been discussed as bearing a risk for headache chronicity. We investigated whether aspirin with caffeine (ASA+) increases headache frequency compared with aspirin alone in migraine, tension-type headache (TTH), and migraine + TTH (MigTTH). The population-based German Headache Consortium Study, which included participants aged 18 to 65 years, collected information about headache and analgesics at baseline (2003-2007, t0, response rate: 55.2%), first follow-up after 1.87 ± 0.39 years (t1, 37.2%), and second follow-up after 3.26 ± 0.60 years (t2, 38.8%). ⋯ Of 509 participants (56.0% women, 42.0 ± 11.8 years [mean ± SD]), 45.2% reported aspirin intake (41.3 ± 10.9 years, 59.6% women, headache days at t0: 2.8 ± 3.1 d/mo, t2: 3.6 ± 4.1 d/mo), 11.8% ASA+ intake (46.0 ± 9.8 years, 73.3%, t0: 4.8 ± 6.1 d/mo, t2: 5.3 ± 5.1 d/mo), and 43.0% no analgesics (41.6 ± 13.1 years, 47.5%, t0: 3.8 ± 6.2 d/mo, t2: 5.3 ± 6.6 d/mo). There was no increase in headache frequency in participants with ASA+ intake compared with aspirin (adjusted, all headache: -0.34 d/mo [95% confidence intervals: -2.50 to 1.82], migraine: -1.36 d/mo [-4.76 to 2.03], TTH: -0.57 d/mo [-4.97 to 3.84], MigTTH: 2.46 d/mo [-5.19 to 10.10]) or no analgesics (all headache: -2.24 d/mo [-4.54 to 0.07], migraine: -3.77 d/mo [-9.22 to 1.68], TTH: -4.68 d/mo [-9.62 to 0.27]; MigTTH: -3.22 d/mo [-10.16 to 3.71]). In our study, ASA+ intake did not increase headache frequency compared with aspirin or no analgesics.

Observational StudyPerioperative Dexamethasone and the Development of Chronic Postmastectomy Pain: A Single-Center Observational Cohort Study.
Perioperative modulation of the surgical inflammatory response has been hypothesized as a viable pharmacological preventive target for the development of chronic pain after surgery. The objective of the current investigation was to evaluate an association between intravenous dexamethasone 4 to 20 mg on the day of surgery with self-reported pain in the breast or axilla 3 months or more after mastectomy. ⋯ Perioperative dexamethasone is not associated with a reduction in the incidence and/or severity of chronic postmastectomy pain. In addition, we did not detect a dose-response effect of dexamethasone on the incidence of chronic postsurgical pain.
