ABSTRACT

OBJECTIVE: To measure the number of unused prescription opioids and disposal habits of patients following orthopedic shoulder surgery. DESIGN: A prospective observational study. SETTING: Academic orthopedic sports medicine department. PATIENTS: Sixty-seven patients undergoing shoulder surgery. INTERVENTIONS: Nine-question opioid use questionnaire. MAIN OUTCOME MEASURES: Responses to an opioid use questionnaire were collected at 2 weeks post-surgery. Outcomes of interest included the amount of initial opioid prescription used and the disposal of excess opioids. RESULTS: Sixty-seven patients completed the opioid use questionnaire. Forty-six (68.7 percent) patients reported having excess opioids at 2 weeks. Of the 46 patients with excess opioids, 57 percent disposed of the excess, and 43 percent planned to keep their opioids. CONCLUSION: Two-thirds of the patients reported having excess opioids, highlighting the issue of an overabundance of unused prescription opioids in America. Utilization of opioid-free pain management strategies and drug disposal kits should be explored to reduce the number of unused and improperly disposed opioids.

ABSTRACT

The purpose of this study is to evaluate the effect of patient demographics and injury characteristics on post-arthroscopic partial meniscectomy (post-APM) patient-reported outcomes (PROs). We hypothesize that the presence of high-grade (Kellgren-Lawrence grades 3-4) arthritis at any location of the knee (medial and lateral compartments, patella, trochlea), comorbidities (psychiatric history, chronic pain, diabetes, smoking, body mass index [BMI] ≥ 30), and lower scores on preoperative patient-reported measures (36-Item Short Form Health Survey [SF-36]) would predict poor outcomes after APM. We conducted a single-center prospective study of 92 patients who underwent APM surgery for associated knee pain. General demographic information and PROs were prospectively collected using SF-12, SF-36, and International Knee Documentation Committee (IKDC) surveys presurgery and at 6-month follow-up. Postsurgery outcomes were patient-reported satisfaction (yes/no) and obtaining a patient-acceptable symptom state (PASS) on IKDC. Data were analyzed with odds ratios (ORs), binomial logistic regression, and Mann-Whitney U test using IBM SPSS software. Demographic and injury characteristics that were poor prognostic indicators (had a decreased likelihood of obtaining PASS on IKDC postsurgery) included having Medicaid insurance (OR: 0.056; 0.003-1.00), chronic pain (OR: 0.106; 0.013-0.873), acute injury (OR: 0.387; 0.164-0.914), and high-grade (KL grades 3-4) medial compartment arthritis (OR: 0.412; 0.174-0.980), and preoperative SF-36 physical health score (PHS; p = 0.023) and mental health score (MHS; p = 0.006) values less than 47 and 48, respectively. Additionally, former smoking history (OR: 0.271; 0.079-0.928) showed a lower likelihood of being satisfied postsurgery. Not having psychiatric history (OR: 14.925; p < 0.001; increased likelihood of obtaining PASS on IKDC score postsurgery) and not having patellar arthritis (OR: 4.082; p = 0.025; increased likelihood of PASS on IKDC) were positive prognostic indicators. This study identifies predictive factors of poor outcomes post-APM; particularly, it highlights the usefulness of SF-36 surveys prior to APM surgery. Patients with low SF-36 score preoperatively may not find APM acceptable. Additional attention should be put on patient demographics (such as psychiatric history, chronic pain, and insurance type) and injury characteristics (presence of arthritis and acute injury) prior to performing APM. LEVEL OF EVIDENCE: II.

ABSTRACT

OBJECTIVES: To evaluate the injury, patient, and microbiological characteristics that place patients at risk for recalcitrant fracture-related infection and osteomyelitis despite appropriate initial treatment. DESIGN: Retrospective chart review. SETTING: Three level I trauma centers. PATIENTS AND PARTICIPANTS: Two hundred and fifty-seven patients undergoing surgical debridement and antibiotic therapy for osteomyelitis from 2003 to 2019. MAIN OUTCOME MEASUREMENTS: Patients were categorized as having undergone serial bone debridement if they had 2 separate procedures a minimum of 6 weeks apart with a full course of appropriate antibiotics in between. Patient records were reviewed for age, injury location, body mass index, smoking status, comorbidities, and culture results including the presence of multidrug-resistant organisms and culture-negative osteomyelitis. RESULTS: A total of 257 patients were identified; 49% (n = 125) had a successful single course of treatment, and 51% (n = 132) required repeat debridement for recalcitrant osteomyelitis. At the index treatment for osteomyelitis, the most common organisms in both groups were methicillin-resistant (MRSA) and methicillin-sensitive Staphylococcus aureus (MSSA). There was no significant difference in incidence of polymicrobial infection between the 2 groups (25% vs. 20%, P = 0.49). The most common organisms cultured at the time of repeat saucerization remained MRSA and MSSA; however, the same organism was cultured from both the index and repeat procedures in only 28% (n = 37) of cases. Diabetic patients, intravenous drug use status, delay to diagnosis, and open fractures of the lower leg are independent risk factors for failure of initial treatment of posttraumatic osteomyelitis. CONCLUSIONS: Successful eradication of fracture-related infection and posttraumatic osteomyelitis is difficult and fails 51% of the time despite standard surgical and antimicrobial therapy. Although MRSA and MSSA remain the most common organisms cultured, patients who fail initial treatment for osteomyelitis often do not culture the same organisms as those obtained at the index procedure. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

ABSTRACT

Ferroportin (Fpn)-expressed at the plasma membrane of macrophages, enterocytes, and hepatocytes-mediates the transfer of cellular iron into the blood plasma. Under the control of the iron-regulatory hormone hepcidin, Fpn serves a critical role in systemic iron homeostasis. Whereas we have previously characterized human Fpn, a great deal of research in iron homeostasis and disorders utilizes mouse models. By way of example, the flatiron mouse, a model of classical ferroportin disease, bears the mutation H32R in Fpn and is characterized by systemic iron deficiency and macrophage iron retention. The flatiron mouse also appears to exhibit a manganese phenotype, raising the possibility that mouse Fpn serves a role in manganese metabolism. At odds with this observation, we have found that human Fpn does not transport manganese, so we considered the possibility that a species difference could explain this discrepancy. We tested the hypothesis that mouse but not human Fpn can transport manganese and performed a comparative analysis of mouse and human Fpn. We examined the functional properties of human Fpn, mouse Fpn, and mutant mouse Fpn by using radiotracer assays in RNA-injected Xenopus oocytes. We found that neither mouse nor human Fpn transports manganese. Mouse and human Fpn share identical properties with respect to substrate profile, calcium dependence, optimal pH, and hepcidin sensitivity. We have also demonstrated that Fpn is not an ATPase pump. Our findings validate the use of mouse models of ferroportin function in iron homeostasis and disease.

ABSTRACT

BACKGROUND: The evaluation of shoulder function requires a combination of physical examination of shoulder range of motion and measures of functional outcome measures. Although efforts have been made to define range of motion for clinical evaluation with respect to functional outcomes, a disconnect still exists when defining a successful outcome. We aim to compare quantitative and qualitative measures of shoulder range of motion with patient-reported outcome measures. METHODS: Data from 100 patients who presented to the office of a single surgeon with a chief complaint of shoulder pain were evaluated for this study. Evaluation included American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form, Single Assessment Numeric Evaluation relative to the shoulder of interest, demographic information, and range of motion in the shoulder of interest. RESULTS: Internal rotation angle did not correlate with patient-reported outcomes, whereas external rotation and forward flexion angles did. Qualitative internal rotation as measured by hand-behind-back reach demonstrated a weak to moderate correlation with patient-reported outcomes, and a significant difference in global range of motion and functional outcome measures were identified in patients who can or cannot reach above the belt line or to the thoracic spine. Qualitative assessment of forward flexion demonstrated that patients who can reach specific anatomic landmarks have significantly improved functional outcome measures, and the same is true when comparing patients who can externally rotate past neutral. CONCLUSIONS: Hand-behind-back reach can be used as a clinical marker of global range of motion and functional outcome measures for patients with shoulder pain. Goniometer measurement of internal rotation has no relationship with patient-reported outcomes. Forward flexion and external rotation assessment with qualitative cutoffs can additionally be used clinically to determine functional outcome for patients with shoulder pain.

ABSTRACT

M-CSF receptor signaling supports the development and survival of mononuclear phagocytes and is thought to play a role in post burn anemia by promoting myeloid lineage bias. We found M-CSF secretion was increased in burn patients and a murine model of post burn ACI, so we neutralized M-CSF in ACI mice to determine if erythropoiesis was improved. Instead, M-CSF blockade further impaired erythropoiesis and erythroid cells access to iron. M-CSF blockade enhanced inflammatory cytokine secretion, further increased systemic neutrophil counts, and led to tissue iron sequestration that was dependent, in part, on augmented IL-6 secretion which induced hepcidin. Deleterious effects of post burn M-CSF blockade were associated with arrest of an iron recycling gene expression signature in the liver and spleen that included Spi-C transcription factor and heme oxygenase-1, which promote heme metabolism and confer a non-inflammatory tone in macrophages. Hepatic induction of these factors in ACI mice was consistent with a recovery of ferroportin gene expression and reflected an M-CSF dependent expansion and differentiation of Spi-C+ monocytes into Kupffer cells. Together, this data indicates M-CSF secretion supports a homeostatic iron recycling program that plays a key role in the maintenance of erythroid cells access to iron following burn injury.
