Mood Disorders Are Associated with Increased Perioperative Opioid Usage and Health Care Costs in Patients Undergoing Knee Cartilage Restoration Procedure.

OBJECTIVE: To identify the prevalence of mood disorder diagnoses in patients undergoing cartilage transplantation procedures and determine the relationship between mood disorders, opioid usage, and postoperative health care costs. DESIGN: Patients with current procedural terminology (CPT) codes for osteochondral autograft transplantation (OAT), osteochondral allograft transplantation (OCA), and autologous chondrocyte implantation (ACI) were identified in the Truven Health Marketscan database (January 2009-September 2014). Patients were grouped based on having a preoperative mood disorder diagnosis (preMDD). Preoperative opioids, postoperative opioids ≥90 days, and health care costs within the year postoperative were compared for those with and without mood disorders. Costs were analyzed, adjusting for preoperative cost, sex, age, and opioid usage, for those with and without mood disorders. RESULTS: A total of 3,682 patients were analyzed (ACI: 690, OAT: 1,294, OCA: 1,698). A quarter of patients had preMDD (ACI: 25.4%, OAT: 20.6%, OCA: 22.7%). Postoperative opioid use was more prevalent in preMDD patients (OAT: 37.1% vs. 24.1%, P < 0.001; OCA: 30.4% vs. 24.8%, P = 0.032; ACI: 33.7% vs. 26.2%, P = 0.070) (odds ratio [OR] ranged from 1.29 to 1.86). First-year postoperative log-transformed costs were significantly greater for preMDD patients (ACI: $7,733 vs. $5,689*, P = 0.012; OAT: $5,221 vs. $3,823*, P < 0.001; OCA: $6,973 vs. $3,992*, P < 0.001; *medians reported). The estimated adjusted first postoperative year cost increase for preMDD OCA patients was 41.7% (P < 0.001) and 28.0% for OAT patients (P = 0.034). There was no statistical difference for ACI patients (P = 0.654). CONCLUSION: Cartilage transplantation patients have a high prevalence of preoperative mood disorders. Opioid use and health care costs were significantly greater for patients with preoperative mood disorder diagnoses. LEVEL OF EVIDENCE: Level III, retrospective therapeutic study.

Intensive multidisciplinary feeding intervention for patients with avoidant/restrictive food intake disorder associated with severe food selectivity: An electronic health record review.

OBJECTIVE: Expert consensus increasingly recognizes intensive multidisciplinary intervention (IMI) as the standard of care to address chronic and severe feeding problems in pediatric populations. In this study, we examined the clinical presentation, intervention characteristics, and treatment outcomes for young children receiving IMI for avoidant restrictive rood intake disorder (ARFID) involving nutritional insufficiencies associated with severe food selectivity. METHOD: We followed the Strengthening the Reporting of Observational Studies in Epidemiology statement to conduct this retrospective chart review. The review focused on consecutive patients (birth to age 21 years) admitted to the IMI program over a 5-year period (June 2014 to June 2019). Inclusion criteria required micronutrient insufficiencies (vitamins A, B12, C, D, E; folic acid; calcium; iron; and zinc) and chronic mealtime refusal behavior (e.g., turning head away from food/spoon, pushing or throwing spoon, crying, screaming, and leaving the table) associated with severe food selectivity. RESULTS: Over the 5-year period, 63 of the patients met study entry requirements. Of these, 60 patients (50 boys and 10 girls; mean age = 72 ± 39 months; range = 23-181) completed intervention (95% treatment completion rate). At discharge, dietary diversity improved by 16 new therapeutic foods (range: 8-22), rapid acceptance and swallowing of new foods exceeded clinical benchmarks (80% or > bites), and risk for nutritional inadequacies declined for this patient cohort. DISCUSSION: Results of the current study support the benefits of IMI to increase dietary variety, improve mealtime behaviors, and enhance nutritional intake for children with ARFID presenting with severe food selectivity.

Dorsal Thompson: Approach to the Proximal Radial Shaft.

SUMMARY: Treatment principles in the management of radial shaft fractures, congruent with all fracture care, are to restore anatomy and function of the limb. Radial shaft fractures are unique in that preserving the anatomic bow of the radius, which allows for its rotation around the ulna during pronation and supination, is essential for proper function. The 2 main approaches for exposure of the proximal or middle third radial diaphyseal fractures are the volar "Henry" and the dorsal "Thompson." This article highlights the benefits of the dorsal Thompson approach, describes the key points of the operative technique, which allow for protection of the posterior interosseous nerve, and provides an overview of the measurable outcomes when using this approach. In the accompanying video, the steps of operative exposure to the proximal radial shaft with careful avoidance of the posterior interosseous nerve are demonstrated.

Responsiveness of patient-reported outcomes in shoulder arthroplasty: what are we actually measuring?

HYPOTHESIS: The purpose of this study was to determine the prevalence and responsiveness of common patient-reported outcome (PRO) tools in patients undergoing primary total shoulder arthroplasty (TSA) for glenohumeral arthritis. METHODS: Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic review of anatomic and reverse TSA studies from PubMed, SportDiscus, Cochrane, and CINAHL was performed. Studies on primary TSA for glenohumeral arthritis that reported at least 1 PRO tool were included in the final analysis. A subgroup analysis of studies that reported preoperative and postoperative PRO scores with at least 2-year follow-up data was evaluated to compare the responsiveness between the different PRO instruments. RESULTS: After full-text review of 490 articles, 74 articles met all inclusion criteria and were included in the final analysis. Anatomic TSA was evaluated in 35 studies, reverse TSA in 32 studies, and both anatomic and reverse in 7 studies. There were a total of 7624 patients, and 25 different PRO tools were used. The most commonly reported PRO tools were the American Shoulder and Elbow Surgeons (44 studies), Constant (42 studies), the visual analog scale for pain (23 studies), and the Simple Shoulder Test (17 studies). A median of 3.0 PRO instruments were used in each study. All instruments had large effect sizes. The University of California at Los Angeles (UCLA) score was found to be the most responsive instrument, and the Single Assessment Numeric Evaluation score was least responsive. The American Shoulder and Elbow Surgeons score was the most responsive instrument that required only patient-reported data. CONCLUSION: Overall, the UCLA score was found to be the most responsive followed by the Adjusted Constant. However, both the UCLA and Adjusted Constant scores require strength and range of motion assessment that may limit their widespread clinical use. The increased responsiveness of these measures, which include objective clinical testing, speaks to the predicted increases in strength and range of motion after shoulder arthroplasty. Of the measures that can be administered without in-person clinical evaluation, the American Shoulder and Elbow Surgeons score and Western Ontario Osteoarthritis of the Shoulder index were the most responsive.

Using Photovoice to Improve Healthy Eating for Children Participating in an Obesity Prevention Program.

Background: Children have benefited from participation in obesity prevention programs. Aims: The objectives of this study were to evaluate the impact of a healthy eating intervention for children in after-school programs and to use photovoice to document change in eating behavior. Methods: Forty-two children in three after-school programs participated. Children participated in lessons from an existing program to learn about healthy eating. A mixed methods study was conducted, using surveys to assess parent and child perceptions, and photovoice to capture children's perceptions of how they and their family changed eating habits. Member-checking was used to verify themes in the data. Twenty parents completed surveys evaluating the program. Results: Findings indicated that children learned program information, were interested in eating healthier (more fruits and vegetables), and quantitative data revealed there was a pre-post trend for eating more fruits at home. They reported that using the photovoice method helped them to monitor their behavior and helped them improve personal and family eating habits. Member checking confirmed themes. A majority of parents were satisfied with the program and reported that their children were discussing what they learned at home. Conclusions: Findings suggested that the photovoice methodology helped children to change in a positive way, increasing their agency in improving their own health and that of their family. Assessing longitudinal change in attitudes about healthy eating and eating behaviors will provide information about whether children maintain gains in knowledge and healthy eating over time.

APOE genotype, hypertension severity and outcomes after intracerebral haemorrhage.

Intracerebral haemorrhage in the elderly is a severe manifestation of common forms of cerebral small vessel disease. Nearly 60% of intracerebral haemorrhage survivors will develop clinical manifestations of small vessel disease progression including recurrent haemorrhage, ischaemic stroke, dementia, late-life depression and gait impairment within 5 years. Blood pressure measurements following intracerebral haemorrhage are strongly associated with this risk. However, aggressive blood pressure lowering in the elderly carries substantial risks. In order to determine whether there might be an opportunity to select individuals at the highest risk for small vessel disease progression for aggressive blood pressure reduction, we investigated whether APOE gene variants ɛ2/ɛ4 modify the association between blood pressure and small vessel disease clinical progression after intracerebral haemorrhage. We conducted a single-centre longitudinal study at a tertiary care referral centre (Massachusetts General Hospital in Boston, MA, USA), analysing 716 consecutive survivors of acute intracerebral haemorrhage, enrolled from January 2006 to December 2016. We conducted research interviews at the time of enrolment and obtained APOE genotypes from peripheral venous blood samples. We followed patients longitudinally by means of validated phone-based research encounters, aimed at gathering measurements of systolic and diastolic blood pressure, as well as information on small vessel disease clinical outcomes (including recurrent haemorrhage, incident ischaemic stroke, incident dementia, incident depression and incident gait impairment). APOE ε4 and systolic blood pressure were associated with the risk of recurrent haemorrhage, ischaemic stroke and post-haemorrhage dementia, depression and gait impairment (all P < 0.05). APOE ε4 and systolic blood pressure interacted to increase the risk of recurrent haemorrhage, ischaemic stroke, dementia and gait impairment (all interaction P < 0.05). Among patients with elevated blood pressure following intracerebral haemorrhage (average systolic blood pressure 120-129 mmHg and diastolic blood pressure <80 mmHg) only those with one or more APOE ε4 copies were at increased risk for one or more small vessel disease outcomes (hazard ratio = 1.97, 95% confidence interval 1.17-3.31). Among haemorrhage survivors with hypertension (stage 1 and beyond) APOE genotype also stratified risk for all small vessel disease outcomes. In conclusion, APOE genotype modifies the already strong association of hypertension with multiple small vessel disease clinical outcomes among intracerebral haemorrhage survivors. These data raise the possibility that genetic screening could inform blood pressure treatment goals in this patient population.

Cardioembolic Stroke Risk and Recovery After Anticoagulation-Related Intracerebral Hemorrhage.

Background and Purpose- Whether to resume oral anticoagulation treatment after intracerebral hemorrhage (ICH) remains an unresolved question. Previous studies focused primarily on recurrent stroke after ICH. We sought to investigate the association between cardioembolic stroke risk, oral anticoagulation therapy resumption, and functional recovery among ICH survivors in the absence of recurrent stroke. Methods- We conducted a joint analysis of 3 observational studies: (1) the multicenter RETRACE study (German-Wide Multicenter Analysis of Oral Anticoagulation Associated Intracerebral Hemorrhage); (2) the Massachusetts General Hospital ICH study (n=166); and (3) the ERICH study (Ethnic/Racial Variations of Intracerebral Hemorrhage; n=131). We included 941 survivors of ICH in the setting of active oral anticoagulation therapy for prevention of cardioembolic stroke because of nonvalvular atrial fibrillation and without evidence of ischemic stroke and recurrent ICH at 1 year from the index event. We created univariable and multivariable models to explore associations between cardioembolic stroke risk (based on CHA2DS2-VASc scores) and functional recovery after ICH, defined as achieving modified Rankin Scale score of ≤3 at 1 year for participants with modified Rankin Scale score of >3 at discharge. Results- In multivariable analyses, the CHA2DS2-VASc score was associated with a decreased likelihood of functional recovery (odds ratio, 0.83 per 1 point increase; 95% CI, 0.79-0.86) at 1 year. Anticoagulation resumption was independently associated with a higher likelihood of recovery, regardless of CHA2DS2-VASc score (odds ratio, 1.89; 95% CI, 1.32-2.70). We found an interaction between CHA2DS2-VASc score and anticoagulation resumption in terms of association with increased likelihood of functional recovery (interaction P=0.011). Conclusions- Increasing cardioembolic stroke risk is associated with a decreased likelihood of functional recovery at 1 year after ICH, but this association was weaker among participants resuming oral anticoagulation therapy. These findings support, including recovery metrics, in future studies of anticoagulation resumption after ICH.

Hypertension and intracerebral hemorrhage recurrence among white, black, and Hispanic individuals.

OBJECTIVE: To clarify whether recurrence risk for intracerebral hemorrhage (ICH) is higher among black and Hispanic individuals and whether this disparity is attributable to differences in blood pressure (BP) measurements and their variability. METHODS: We analyzed data from survivors of primary ICH enrolled in 2 separate studies: (1) the longitudinal study conducted at Massachusetts General Hospital (n = 759), and (2) the ERICH (Ethnic/Racial Variations of Intracerebral Hemorrhage) study (n = 1,532). Participants underwent structured interview at enrollment (including self-report of race/ethnicity) and were followed longitudinally via phone calls and review of medical records. We captured systolic BP (SBP) and diastolic BP measurements, and quantified variability as SBP and diastolic BP variation coefficients. We used multivariable (Cox regression) survival analysis to identify risk factors for ICH recurrence. RESULTS: We followed 2,291 ICH survivors (1,121 white, 529 black, 605 Hispanic, and 36 of other race/ethnicity). Both black and Hispanic patients displayed higher SBP during follow-up (p < 0.05). Black participants also displayed greater SBP variability during follow-up (p = 0.032). In univariable analyses, black and Hispanic patients were at higher ICH recurrence risk (p < 0.05). After adjusting for BP measurements and their variability, both Hispanic (hazard ratio = 1.51, 95% confidence interval 1.14-2.00, p = 0.004) and black (hazard ratio = 1.98, 95% confidence interval 1.36-2.86, p < 0.001) patients remained at higher risk of ICH recurrence. CONCLUSION: Black and Hispanic patients are at higher risk of ICH recurrence; hypertension severity (average BP and its variability) does not fully account for this finding. Additional studies will be required to further elucidate determinants for this health disparity.

Reflecting on explanatory ability: A mechanism for detecting gaps in causal knowledge.

People frequently overestimate their understanding-with a particularly large blind-spot for gaps in their causal knowledge. We introduce a metacognitive approach to reducing overestimation, termed reflecting on explanatory ability (REA), which is briefly thinking about how well one could explain something in a mechanistic, step-by-step, causally connected manner. Nine experiments demonstrated that engaging in REA just before estimating one's understanding substantially reduced overestimation. Moreover, REA reduced overestimation with nearly the same potency as generating full explanations, but did so 20 times faster (although only for high complexity objects). REA substantially reduced overestimation by inducing participants to quickly evaluate an object's inherent causal complexity (Experiments 4-7). REA reduced overestimation by also fostering step-by-step, causally connected processing (Experiments 2 and 3). Alternative explanations for REA's effects were ruled out including a general conservatism account (Experiments 4 and 5) and a covert explanation account (Experiment 8). REA's overestimation-reduction effect generalized beyond objects (Experiments 1-8) to sociopolitical policies (Experiment 9). REA efficiently detects gaps in our causal knowledge with implications for improving self-directed learning, enhancing self-insight into vocational and academic abilities, and even reducing extremist attitudes.

Adult-derived stem cells and their potential for use in tissue repair and molecular medicine.

This report reviews three categories of precursor cells present within adults. The first category of precursor cell, the epiblast-like stem cell, has the potential of forming cells from all three embryonic germ layer lineages, e.g., ectoderm, mesoderm, and endoderm. The second category of precursor cell, the germ layer lineage stem cell, consists of three separate cells. Each of the three cells is committed to form cells limited to a specific embryonic germ layer lineage. Thus the second category consists of germ layer lineage ectodermal stem cells, germ layer lineage mesodermal stem cells, and germ layer lineage endodermal stem cells. The third category of precursor cells, progenitor cells, contains a multitude of cells. These cells are committed to form specific cell and tissue types and are the immediate precursors to the differentiated cells and tissues of the adult. The three categories of precursor cells can be readily isolated from adult tissues. They can be distinguished from each other based on their size, growth in cell culture, expressed genes, cell surface markers, and potential for differentiation. This report also discusses new findings. These findings include the karyotypic analysis of germ layer lineage stem cells; the appearance of dopaminergic neurons after implantation of naive adult pluripotent stem cells into a 6-hydroxydopamine-lesioned Parkinson's model; and the use of adult stem cells as transport mechanisms for exogenous genetic material. We conclude by discussing the potential roles of adult-derived precursor cells as building blocks for tissue repair and as delivery vehicles for molecular medicine.
