Intraoperative Hypotension and Myocardial Injury After Noncardiac Surgery in Adults With or Without Chronic Hypertension: A Retrospective Cohort Analysis.
The risk of myocardial injury progressively increases at intraoperative mean arterial pressures (MAPs) ≤65 mm Hg. Higher pressures might be required in chronically hypertensive patients. We aimed to test the hypothesis that the harm threshold is higher in patients with chronic hypertension than in normotensive patients. ⋯ Baseline blood pressure of the hypertensive patients was only moderately increased on average, and the event rate was low. Nonetheless, we were not able to demonstrate a difference in the harm threshold between normotensive and chronically hypertensive patients. Our results do not support the theory that hypertensive patients should be kept at higher intraoperative pressures than normotensive patients.

The nociceptive flexion reflex (NFR) is a spinally mediated withdrawal response and is used as an electrophysiological marker of descending modulation of spinal nociception. Chemical and pharmacological modulation of nociceptive neurotransmission at the spinal level has been evidenced by direct effects of neurotransmitters and pharmacological agents on the NFR. Largely unexplored are, however, the effects of nonpharmacological noninvasive conservative interventions on the NFR. ⋯ Such interventions may help prevent and treat chronic pain characterized by enhanced spinal nociception. Furthermore, given the responsiveness of the NFR to conservative interventions, the NFR assessment seems to be an appropriate tool in empirical evaluations of treatment strategies. PROSPERO registration number: CRD42020164495.

Intensive interdisciplinary pain treatment (IIPT) for youth with high impact chronic pain has been found to be effective in improving child symptoms and functioning. However, it remains unclear how these interventions impact the parents' own well-being, as well as cognitions and behaviours which are known to influence child pain and functioning. Thus, the current study sought to determine the effect of IIPT on parent mental health, cognitions and behaviours in parents of youth attending IIPT with their child. ⋯ Although parents appear to benefit from attending an IIPT with their child, RCTs are needed to substantiate the effect of these interventions on important aspects of parent well-being and functioning.

Pain, distress, and depression are predictors of posttrauma pain and recovery. We hypothesized that pretrauma characteristics of the person could predict posttrauma severity and recovery. ⋯ The results indicate that 3 commonly reported predictors of chronic musculoskeletal pain (BPI, TIDS, PHQ-9) could be predicted by variables not related to the injurious event itself. The 3-trajectory recovery model mirrors other prior research in the field, though 2 trajectories look very similar at baseline despite very different 12-month outcomes. Researchers are encouraged to design studies that integrate, rather than exclude, the pre-existing variables described here.

Recently, a new classification system for chronic pain was included in the 11th edition of the International Classification of Diseases (ICD-11). This study aims to investigate how expectancies of coping, that is pain catastrophizing and general self-efficacy, are associated with ICD-11 chronic pain categories in a large pain clinic population. Furthermore, we investigate how coping expectancies are associated with pain-related disability, cross-sectionally and longitudinally across the novel pain classifications. ⋯ Levels of coping expectancies, demographic characteristics, pain-related disability and pain intensity are similar across all ICD-11 chronic pain diagnostic categories. Thus, chronic primary pain is not stronger associated with psychosocial factors such as catastrophizing and self-efficacy than chronic secondary pain. Therefore, chronic pain patients, independent of diagnosis, may benefit from the assessment of these psychosocial factors and targeted interventions such as CBT should be considered.
