Strategies aimed at preventing long-term opioid use in trauma and orthopaedic surgery: a scoping review.

BACKGROUND: Long-term opioid use, which may have significant individual and societal impacts, has been documented in up to 20% of patients after trauma or orthopaedic surgery. The objectives of this scoping review were to systematically map the research on strategies aiming to prevent chronic opioid use in these populations and to identify knowledge gaps in this area. METHODS: This scoping review is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) Checklist. We searched seven databases and websites of relevant organizations. Selected studies and guidelines were published between January 2008 and September 2021. Preventive strategies were categorized as: system-based, pharmacological, educational, multimodal, and others. We summarized findings using measures of central tendency and frequency along with p-values. We also reported the level of evidence and the strength of recommendations presented in clinical guidelines. RESULTS: A total of 391 studies met the inclusion criteria after initial screening from which 66 studies and 20 guidelines were selected. Studies mainly focused on orthopaedic surgery (62,1%), trauma (30.3%) and spine surgery (7.6%). Among system-based strategies, hospital-based individualized opioid tapering protocols, and regulation initiatives limiting the prescription of opioids were associated with statistically significant decreases in morphine equivalent doses (MEDs) at 1 to 3 months following trauma and orthopaedic surgery. Among pharmacological strategies, only the use of non-steroidal anti-inflammatory drugs and beta blockers led to a significant reduction in MEDs up to 12 months after orthopaedic surgery. Most studies on educational strategies, multimodal strategies and psychological strategies were associated with significant reductions in MEDs beyond 1 month. The majority of recommendations from clinical practice guidelines were of low level of evidence. CONCLUSIONS: This scoping review advances knowledge on existing strategies to prevent long-term opioid use in trauma and orthopaedic surgery patients. We observed that system-based, educational, multimodal and psychological strategies are the most promising. Future research should focus on determining which strategies should be implemented particularly in trauma patients at high risk for long-term use, testing those that can promote a judicious prescription of opioids while preventing an illicit use, and evaluating their effects on relevant patient-reported and social outcomes.

Does physical activity moderate the association between alcohol drinking and all-cause, cancer and cardiovascular diseases mortality? A pooled analysis of eight British population cohorts.

OBJECTIVE: To examine whether physical activity (PA) moderates the association between alcohol intake and all-cause mortality, cancer mortality and cardiovascular diseases (CVDs) mortality. DESIGN: Prospective study using 8 British population-based surveys, each linked to cause-specific mortality: Health Survey for England (1994, 1998, 1999, 2003, 2004 and 2006) and Scottish Health Survey (1998 and 2003). PARTICIPANTS: 36 370 men and women aged 40 years and over were included with a corresponding 5735 deaths and a mean of 353 049 person-years of follow-up. EXPOSURES: 6 sex-specific categories of alcohol intake (UK units/week) were defined: (1) never drunk; (2) ex-drinkers; (3) occasional drinkers; (4) within guidelines (<14 (women); <21 (men)); (5) hazardous (14-35 (women); 21-49 (men)) and (6) harmful (>35 (women) >49 (men)). PA was categorised as inactive (≤7 MET-hour/week), active at the lower (>7.5 MET-hour/week) and upper (>15 MET-hour/week) of recommended levels. MAIN OUTCOMES AND MEASURES: Cox proportional-hazard models were used to examine associations between alcohol consumption and all-cause, cancer and CVD mortality risk after adjusting for several confounders. Stratified analyses were performed to evaluate mortality risks within each PA stratum. RESULTS: We found a direct association between alcohol consumption and cancer mortality risk starting from drinking within guidelines (HR (95% CI) hazardous drinking: 1.40 (1.11 to 1.78)). Stratified analyses showed that the association between alcohol intake and mortality risk was attenuated (all-cause) or nearly nullified (cancer) among individuals who met the PA recommendations (HR (95% CI)). CONCLUSIONS: Meeting the current PA public health recommendations offsets some of the cancer and all-cause mortality risk associated with alcohol drinking.

Sixteen weeks of resistance training decrease plasma heat shock protein 72 (eHSP72) and increase muscle mass without affecting high sensitivity inflammatory markers' levels in sarcopenic men.

BACKGROUND: Sarcopenia has been associated with increased systemic inflammation and risk of physical disability in older adults. Recently, extracellular heat shock protein 72 (eHSP72) was proposed as a biomarker of sarcopenia but its response to interventions designed to increase muscle mass has never been evaluated. AIMS: The present study was designed to (1) assess eHSP72 levels following resistance training and, (2) determine whether changes in eHSP72 correlate to changes in muscle mass and inflammatory markers. METHODS: A total of 26 sarcopenic men participated in a 16-week resistance training program. The following variables were measured pre-post-intervention: plasma HSP72, serum high sensitivity (hs) inflammatory markers: interleukin-6 (hsIL-6), C-reactive protein (hsCRP), and tumor necrosis factor alpha (hsTNF-α), lean body mass (LBM) and appendicular muscle mass index (appMMI). RESULTS: eHSP72 was detected in 47 % of our participants and its level significantly decreased (P = 0.04) after the intervention, with a concomitant increase in several LBM variables and appMMI (all P < 0.035). Serum hsIL-6, hsCRP and hsTNF-α changes did not reach significance. Baseline hsIL-6 and hsCRP levels were negatively correlated with several LBM variables but solely baseline hsIL-6 was associated with changes in appLBM. No correlations were found between changes in measured variables. DISCUSSION: Attenuation of eHSP72 following resistance training in parallel with increase in LBM variables showed a concordance between the evolution of this biomarker and a clinical outcome relevant to sarcopenia. CONCLUSION: Nevertheless, the low bloodstream detection rate of eHSP72 in a sarcopenic otherwise healthy population might limit its use in clinical settings for now.

Early postoperative feeding--results of a North American survey.

Early postoperative feeding (EPOF) practices among North American institutions were investigated using a survey questionnaire to obtain descriptive information regarding the overall utilization and criteria used to identify candidates for EPOF. EPOF was defined as the initiation of enteral nutrition support two to 48 hours postoperatively in major abdominal and thoracic surgical patients. Two hundred and ninety-seven questionnaires were mailed; 170 were completed. Sixty-nine (41%) institutions reported using EPOF. Feeding was initiated less than 12 hours postoperatively in 16% of centres; 84% reported EPOF 13-48 hours postoperatively. The majority (88%) of institutions did not have a specific nutritional guideline for determining which patients should receive EPOF. Objective and subjective nutritional indices, degree of preoperative malnutrition and type of surgery were considered by 23% of respondents when determining the need for EPOF. Percent weight loss, albumin and the anticipated postoperative NPO were considered the most reliable objective indices while decreased dietary intake, cachexic appearance and anorexia were considered the most reliable subjective indices. The results reveal that less than 50% of institutions surveyed use EPOF in major abdominal and thoracic surgical patients and the criteria used to identify candidates for EPOF were found to be variable.
