Hip Fracture With Elevated Troponin: Harbinger of Mortality or Need for Accelerated Surgery?

OBJECTIVE: To determine the association of elevated troponin levels with time to surgery and the risk of mortality and other key clinical outcomes among elderly patients with hip fracture who had measured troponin levels at hospital admission. DESIGN: Retrospective cohort study. SETTING: Single academic trauma center. PATIENTS: We included 299 consecutive patients 60 years of age or older with a hip fracture and cardiac troponin levels measured at the time of hospital admission. INTERVENTION: Patients with elevated cardiac troponin levels at hospital admission (n = 43) compared with patients with normal troponin levels at admission (n = 256). MAIN OUTCOME MEASURES: Time to surgery, 90-day mortality, and major complications within 90 days of injury. RESULTS: The median age of the cohort was 80 years (interquartile range, 70-87 years), 59% were female, and 86% were living independently before their injury. Elevated troponin levels were associated with a 21-hour [95% confidence interval (CI), 12 to 32, P < 0.001] increase in the median time from admission to surgery (43 vs. 22 hours). Elevated troponin levels were also associated with a 14% (95% CI, 0% to 29%, P = 0.01) absolute increase in 90-day mortality (28% vs. 14%). Patients with elevated troponins were 15% (95% CI, -1% to 30%, P = 0.06) more likely to have a major complication (37% vs. 23%); however, the difference did not reach statistical significance. CONCLUSIONS: Among patients with a hip fracture and measured troponin levels, elevated troponin levels were associated with significant delays in surgery and increased 90-day mortality. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Alignment Between Resident Medical Condition Regard Scale Scores and Desire to Treat Patients With Opioid Use Disorder.

OBJECTIVES: To (1) evaluate attitudes of resident physicians towards patients with opioid use disorder (OUD) and (2) identify characteristics associated with residents' desire to treat patients with OUD. METHODS: We administered the validated medical condition regard scale (MCRS), a question regarding desire to treat patients with OUD, and a demographic questionnaire to residents in multiple specialties at the University of New Mexico (family medicine, psychiatry, emergency medicine, internal medicine, anesthesiology, general surgery, obstetrics/gynecology). RESULTS: One hundred sixty-three of 307 residents (53%) responded to the survey; 146 provided complete responses to the "desire" and MCRS questions. Response rates, MCRS, and desire to care for patients with OUD varied between specialties ( P < 0.001); family medicine had highest MCRS and desire to care scores; surgery, anesthesiology had low scores. MCRS and resident "desire" scores were highly correlated on univariate analysis ( r = 0.73, P < 0.001); resident demographics were not. On logistic regression, resident desire to care for OUD increased with MCRS scores ( P < 0.001). The predicated probability of desire to care for OUD was ≥80% with MCRS >57; MCRS classification skill on receiver operator curve analysis was excellent (area under curve = 0.81 [95% confidence interval 0.74, 0.88], and specialty-adjusted MCRS area under curve = 0.85 [95% confidence interval 0.79, 0.91]). CONCLUSIONS: High resident regard for patients with OUD on MCRS was directly related to resident's desire to provide OUD care. MCRS may offer a tool to alter or individualize OUD education, potentially influencing the OUD workforce of the future.

Rehabilitation Principles to Consider for Anterior Cruciate Ligament Repair.

CONTEXT: Injury to the anterior cruciate ligament (ACL) is among the most common orthopaedic injuries, and reconstruction of a ruptured ACL is a common orthopaedic procedure. In general, surgical intervention is necessary to restore stability to the injured knee, and to prevent meniscal damage. Along with surgery, intense postoperative physical therapy is needed to restore function to the injured extremity. ACL reconstruction (ACLR) has been the standard of care in recent decades, and advances in surgical technology have reintroduced the prospect of augmented primary repair of the native ACL via a variety of methods. EVIDENCE ACQUISITION: A search of PubMed database of articles and reviews available in English was performed through 2020. The search terms ACLR, anterior cruciate ligament repair, bridge enhanced acl repair, suture anchor repair, dynamic intraligamentary stabilization, internal bracing, suture ligament augmentation, and internal brace ligament augmentation were used. STUDY DESIGN: Clinical review. LEVEL OF EVIDENCE: Level 5. RESULTS: No exact consensus exists on effective rehabilitation protocols after ACL repair techniques, as the variation in published protocols seem even greater than the variation in those for ACLR. For some techniques such as internal bracing and dynamic interligamentary stabilization, it is likely permissible for the patients to progress to full weightbearing and discontinue bracing sooner. However, caution should be applied with regard to earlier return to sport than after ACLR as to minimize risk for retear. CONCLUSION: More research is needed to address how physical therapies must adapt to these innovative repair techniques. Until that is accomplished, we recommend that physical therapists understand the differences among the various ACL surgery techniques discussed here and work with the surgeons to develop a rehabilitation protocol for their mutual patients.

A Novel Presentation of Bladder Mass: Self-palpation by a Patient With Cystocele.

INTRODUCTION: This case describes diagnosis of a T2 transitional cell carcinoma in an 89-year-old woman with known cystocele and urinary retention managed with clean intermittent self-catheterization. CASE: While self-catheterizing, the patient noted a palpable mass in her cystocele. She eventually pursued urologic evaluation of this mass, which ultimately led to her diagnosis. This is the first reported case of transitional cell carcinoma being found on self-examination by palpating a cystocele.

Circuit specificity in the inhibitory architecture of the VTA regulates cocaine-induced behavior.

Afferent inputs to the ventral tegmental area (VTA) control reward-related behaviors through regulation of dopamine neuron activity. The nucleus accumbens (NAc) provides one of the most prominent projections to the VTA; however, recent studies have provided conflicting evidence regarding the function of these inhibitory inputs. Using optogenetics, cell-specific ablation, whole cell patch-clamp and immuno-electron microscopy, we found that NAc inputs synapsed directly onto dopamine neurons, preferentially activating GABAB receptors. GABAergic inputs from the NAc and local VTA GABA neurons were differentially modulated and activated separate receptor populations in dopamine neurons. Genetic deletion of GABAB receptors from dopamine neurons in adult mice did not affect general or morphine-induced locomotor activity, but markedly increased cocaine-induced locomotion. Collectively, our findings demonstrate notable selectivity in the inhibitory architecture of the VTA and suggest that long-range GABAergic inputs to dopamine neurons fundamentally regulate behavioral responses to cocaine.
