Elbow Arthritis.

Elbow arthritis is an uncommon condition that can cause debilitating pain, stiffness, or instability. The most common etiologies include rheumatoid arthritis, posttraumatic arthritis, and primary osteoarthritis. Treatment begins with nonsurgical modalities, including activity modification, anti-inflammatories, hand therapy, and corticosteroids. Operative intervention may be considered once nonsurgical management has failed. Surgical treatment depends on the underlying etiology, chief complaint, patient age, and functional demand. Advances in technology, especially arthroscopic techniques, have expanded the treatment options available to surgeons. The goals of treatment include pain relief and restoration of functional range of motion. The purpose of this article is to review the pertinent soft tissue and osseous anatomy, discuss the etiologies, review the principles of diagnosis and evaluation, and finally, study the treatment options for elbow arthritis.

Medical Versus Invasive Management of Non-ST Segment Elevation Myocardial Infarction in Diabetes Mellitus.

INTRODUCTION: While management guidelines clearly indicate treatment algorithms for ST-segment elevation myocardial infarction, evidence behind treatment of other forms of acute coronary syndrome among diabetic patients has been inconclusive. This study examines diabetic patients with non ST-segment elevation myocardial infarction (NSTEMI) who were subsequently treated conservatively or with an invasive approach. METHODS: Diabetic patients admitted to our health network with NSTEMI between January 2013-2018 were identified. Data collected included demographics, treatment, survival, recurrence of myocardial infarction (MI), stroke and additional revascularization procedures. Historical data including comorbid factors present at time of NSTEMI and history of revascularization procedures were also collected. RESULTS: A total of 357 patients met exclusion criteria. 172 were treated medically and 185 with PCI. A total of 78 deaths occurred over the five year observation period. 48 patients who were treated medically died while 30 patients treated with PCI died. After initial medical management, nine patients went on to require PCI while 19 patients treated with PCI required additional PCI. Recurrence of MI occurred in 19.8 % in medically managed patients and 18.6 % in patients who underwent PCI. Multivariable analysis was completed with the Kaplan-Meier method to estimate the survival function and Cox proportional-hazard models to investigate association between the variables and survival time. CONCLUSIONS: In this single center study, diabetic patients treated with PCI had lower rates of all-cause mortality over the five-year study period compared to medical management. There was no difference in stroke events, recurrent MI, or revascularization between the two groups although patients from the PCI group showed a trend towards higher risk for repeat interventions. Treatment selection bias remains the major limitation of this study and thus, the results of the comparison of therapeutic choices should be viewed as hypothesis generating.

Risk Factors and Reasons for Emergency Department Visits Within 30 Days of Elective Hand Surgery: An Analysis of 3,261 Patients.

Background: The frequency of hand and elbow surgeries occurring in outpatient and elective settings is on the rise. Emergency department (ED) visits in the postoperative period are increasingly used as quality measures for surgical care. The aim of this study is to determine the number of postoperative ED visits, the primary reason for these visits, and to identify risk factors associated with these visits. Methods: We examined all elective hand and elbow procedures performed at two hospitals within a single healthcare network between 2008 and 2017. A total of 3,261 patients met the study criteria. Descriptive statistics were calculated for our population, followed by univariate and multivariate analyses, to identify risk and protective factors associated with ED visits in the first 30 days after surgery. Results: Eighty-seven of 3,261 patients presented to the ED within 30 days of their operation (2.7%). The most common reasons for ED visits were related to pain (28.7%), swelling (26.4%), and concerns for infection (20.7%). Univariate analysis indicated history of drug use, number of procedures, smoking history, and serum albumin <3.5 mg/dL as risk factors for returns to the ED. Multivariate analysis identified history of drug use, number of procedures, and serum albumin <3.5 mg/dL as independent risk factors. Smoking history failed to achieve statistical significance as an independent risk factor. Both univariate and multivariate analyses identified age >60 years as protective for postoperative ED visits. Conclusions: ED visits within the first 30 days after elective hand surgery are relatively common, despite remarkably low complication rates among these procedures. This information may help to improve risk stratification in these patients, and to aid in the development of enhanced postoperative follow-up strategies to reduce unnecessary utilization of emergency medical services. Level of Evidence: Level III (Therapeutic).

Patient-Related Risk Factors Associated With Surgical Site Complications After Elective Hand Surgery.

BACKGROUND: The purpose of this study was to identify independent risk factors associated with an increased rate of surgical site complications after elective hand surgery. METHODS: This study is a retrospective review of all patients who underwent elective hand, wrist, forearm, and elbow surgery over a 10-year period at a single institution. Electronic medical records were reviewed, and information regarding patient demographics, past medical and social history, perioperative laboratory values, procedures performed, and surgical complications was collected. Surgical site complications included surgical site infections, seromas or hematomas, and delayed wound healing or wound dehiscence. A univariate analysis was then performed to identify potential risk factors, which were then included in a multivariate regression analysis. RESULTS: A total of 3261 patients who underwent elective hand surgery and met the above inclusion and exclusion criteria were included in this study. The mean age was 57 years, with 65% female and 35% male patients. The overall surgical complication rate was 2.2%. Univariate analysis of patient factors identified male sex; number of procedures >1; history of drug, alcohol, or smoking use; American Society of Anesthesiologists (ASA) class III and IV; and serum albumin <3.5 mg/dL to be significantly associated with complications. However, multivariate regression analysis identified that only ASA class III and IV (odds ratio = 3.27) was significantly associated with surgical complications. CONCLUSIONS: Patients classified as ASA class III or IV were identified to be at a significantly increased risk of complications following elective hand surgery. Health factors which triage patients into these 2 groups may represent potentially modifiable factors to mitigate perioperative risk in the elective hand surgery population.

Effect of Smoking on Short-term Postoperative Complications After Elective Upper Extremity Surgery.

Background: There is a paucity of literature exploring the impact of smoking on short-term complications, readmissions, and reoperations after elective upper extremity surgery using a large multicenter national database. We hypothesized that smokers will have an increased rate of complications, readmissions, and reoperations compared with a cohort of nonsmokers undergoing elective upper extremity surgery. Methods: Patient data were collected from the American College of Surgeons National Surgical Quality Improvement Program database between the years 2012 and 2017. Patients were included if they underwent elective surgery of the upper extremity using 338 predetermined Current Procedural Terminology codes. The data collected were divided into patient demographics, comorbidities, perioperative variables, and 30-day complications. Current smoking status was defined as smoking within 1 year prior to surgery. The incidence of surgical complications, reoperations, and readmissions was compared between the 2 cohorts using multivariable regression analysis. Results: Of the 107 943 patients undergoing elective surgeries of the upper extremity, 73 806 met the inclusion criteria. Of these, 57 986 (78.6%) were nonsmokers in the year prior to surgery, and 15 820 (21.4%) were current smokers. Between these groups, current smokers were younger (P < .001), more often men (P < .001), had lower body mass index (P < .001), and more often underwent procedures that involved bone manipulation (P < .001). Multivariate regression analysis defined current smoking as significantly associated with overall surgical site complications, superficial surgical site infections, deep surgical site infections, reoperation, and readmission. Conclusion: Current smoking was significantly associated with an increase in all surgical site complications, readmissions, and reoperations after elective upper extremity surgery. Surgeons should consider smoking a modifiable risk factor for postoperative complications and appropriately counsel patients on outcomes and complications given the elective nature of upper extremity surgery.

Effect of Diabetes and Hemoglobin A1c on Complications Following Elective Hand Surgery.

Background: Limited research exists investigating the association between diabetes and glycemic control on complications following elective hand surgery. The goal of this research was to assess the incidence of complications within 30 days of elective hand surgery in a large population of diabetic patients compared to a population of non-diabetics. Furthermore, we sought to examine the relationship of glycemic control, as measured by HbA1c, and postoperative complications. Methods: We performed a retrospective review of electronic medical records at our institution of all patients who underwent elective hand, forearm, or elbow surgery from the dates of January 1st, 2008 to December 31st, 2017. Patients were categorized as diabetic or non-diabetic and most recent HbA1c was documented. Multivariable analysis was employed to compare the incidence of surgical complications within 30 days between the diabetics and non-diabetic populations, adjusting for baseline patient characteristics. Results: A total of 3,261 patients met the inclusion criteria. There were 646 (20%) diabetic patients and 2,615 (80%) non-diabetic patients. No difference was found in the overall rate of complications between the cohort of diabetic and non-diabetic patients. Additionally, statistical analysis found no difference in the complication rate between insulin and non-insulin controlled diabetics. Rates of complications were stratified based on HbA1c level and statistical analysis found no increased risk of complications with increased hemoglobin A1c value. Conclusions: In our present study we were not able to demonstrate any significant difference in the 30 day complication rates between and non-diabetics undergoing elective hand surgery. This study attempted to aid in risk stratification of diabetic patients by evaluating preoperative glycemic indices in the form of HbA1c.

Outcomes of surgical versus transcatheter aortic valve replacement in nonagenarians- a systematic review and meta-analysis.

Introduction: Since the approval of transcatheter aortic valve replacement (TAVR), nonagenarian group patients are being increasingly considered for TAVR. Therefore, we compared the clinical outcomes of surgical aortic valve replacement (SAVR) vs TAVR in nonagenarians with severe aortic stenosis. Methods: A literature search was performed using MEDLINE, Embase, Web of Science, Cochrane, and Clinicaltrials.gov for studies reporting the comparative outcomes of TAVR versus SAVR in nonagenarians. The primary endpoint was short-term mortality. Secondary endpoints were post-operative incidences of stroke or transient ischemic attack (TIA), vascular complications, acute kidney injury (AKI), transfusion requirement, and length of hospital stay. Results: Four retrospective studies qualified for inclusion with a total of 8,389 patients (TAVR = 3,112, SAVR = 5,277). Short-term mortality was similar between the two groups [RR = 0.91 (95% CI: 0.76-1.10), p = 0.318]. The average length of hospital stay was shorter by 3 days in the TAVR group (p = 0.037). TAVR was associated with a significantly lower risk of AKI [RR = 0.72 (95% CI: 0.62-0.83), p < 0.001] and a lower risk of transfusion [RR = 0.71 (95% CI: 0.62-0.81), p < 0.001]. There was no difference in risk of stroke/TIA[RR = 1.01 (95% CI: 0.70-1.45), p = 0.957]. The risk of vascular complications was significantly higher in the TAVR group [RR = 3.39 (95% CI: 2.65-4.333), p < 0.001]. Conclusion: In this high-risk population, TAVR compared to SAVR has similar short-term mortality benefit but has lower risks of perioperative complications and a higher number of patients being discharged to home.

Type 2 Myocardial Infarction: CURRENT CONCEPTS AND OUR EXPERIENCE WITH CARDIAC REHABILITATION.

BACKGROUND: Type 2 myocardial infarction (T2MI) is commonly encountered in clinical practice, yet little is known about this challenging condition. Outpatient cardiac rehabilitation (CR) is an integral component in the care of patients with MI. However, specific recommendations for CR, information on the feasibility of participation, and outcome measures for patients with T2MI are lacking. CLINICAL CONSIDERATIONS: The frequency of T2MI is markedly variable and depends on the studied population, disease definition, adjudication process, cardiac troponin assays, and cutoff values used to make the diagnosis of T2MI. Clinically, it is difficult to distinguish T2MI from type 1 MI or myocardial injury. Type 2 myocardial infarction occurs due to myocardial oxygen supply-demand mismatch without acute atherothrombotic plaque disruption and is associated with adverse short- and long-term prognoses. Currently, there are substantial gaps in knowledge regarding T2MI and there are no clear guidelines for the optimal management of these patients. SUMMARY: In this article, we present important current concepts surrounding T2MI including the definition, pathophysiology, epidemiology, diagnosis, prognosis, and management. We also discuss referral patterns to CR and participation rates and provide our experience with a case series of 17 patients. Very few patients with T2MI are referred to and participate in CR. Our small case series indicated that patients with T2MI respond favorably to CR and that exercise training following standard guidelines appears safe and is well tolerated.

Glenohumeral arthrodesis.

Glenohumeral arthrodesis is a salvage procedure indicated for brachial plexus palsy, refractory instability, humeral and/or glenoid bone loss, deltoid and rotator cuff insufficiency, and chronic infections. The aim is to provide a painless, stable shoulder that is positioned to maximize function. Scapulothoracic motion as well as motion of the elbow and hand deliver satisfactory function in most patients. Intra-articular, extra-articular, and more commonly, combined techniques involving glenohumeral and humeroacromial fusion, have been described. More recently, authors have reported arthroscopic assisted techniques for shoulder arthrodesis with promising results as well as less complicated conversion from shoulder arthrodesis to reverse total shoulder arthroplasty. Despite advances in materials and techniques, glenohumeral arthrodesis continues to be associated with complication rates as high as 43%. A thorough understanding of the indications, contraindications, outcomes, and complications is paramount to improving patient results. Glenohumeral arthrodesis is a safe and effective procedure for the appropriate indications. The high frequency of complications mandates a frank preoperative discussion to ensure that each patient understands the magnitude of the procedure, its risks, possible complications, and expected outcome.

Systematic review and network meta-analysis of subscapularis management techniques in anatomic total shoulder arthroplasty.

BACKGROUND: Controversy exists regarding the optimal subscapularis management technique in patients undergoing anatomic total shoulder arthroplasty. The purpose of this study was to compare clinical, radiographic, and functional outcomes between subscapularis tenotomy (ST), lesser tuberosity osteotomy (LTO), and subscapularis peel (SP) techniques. METHODS: We performed a level III systematic review and network meta-analysis comparing ST, LTO, and SP in patients undergoing anatomic total shoulder arthroplasty. Our primary collection endpoints included range of motion, subscapularis function, subscapularis healing, functional patient-reported outcomes, complications, and revision surgery. Data were pooled and network meta-analysis was performed owing to the comparison of 3 groups. RESULTS: Eight studies met our inclusion criteria for meta-analysis. There was no difference in sex or primary diagnosis between the 3 cohorts. No significant difference was found in postoperative external rotation or forward flexion between the groups. Meta-analysis found the SP cohort to have significantly greater internal rotation strength than the ST cohort. The belly-press test results were negative most commonly in the LTO group, and there was a significant difference compared with the ST or SP group (P < .0001). The weighted-mean healing rate for the LTO site was 98.9% on radiographic imaging. There was a significantly higher ultrasound healing rate in the LTO cohort than in the ST and SP cohorts. All groups had good postoperative patient-reported outcome scores (average American Shoulder and Elbow Surgeons score range, 78.6-87) and a relatively low rate of complications (3%). CONCLUSION: This network meta-analysis demonstrates that the LTO group has superior healing and postoperative subscapularis-specific physical examination test results compared with the ST and SP groups. However, no difference in postoperative range of motion was found between the groups, and all techniques demonstrated good functional patient-reported outcomes, with a low rate of postoperative complications. These findings provide evidence-based support that ST, SP, and LTO all demonstrate similar outcomes; therefore, selection should be based on surgeon experience and comfort.

Massive purulent pericarditis presenting as cardiac tamponade.

Acute bacterial pericarditis is rarely encountered in the modern antibiotic era. Purulent pericarditis is a serious form of bacterial pericarditis with high mortality. It can rapidly progress to cardiac tamponade, leading to hemodynamic instability, septic shock, and death if left untreated. Here we present a case of massive purulent pericarditis with cardiac tamponade that was successfully managed with intravenous antibiotics and drainage in a young immunocompetent man.

Incidence and predictors of positive intraoperative cultures in primary shoulder arthroplasty following prior ipsilateral shoulder surgery.

BACKGROUND: To our knowledge, the rate of positive intraoperative cultures in patients undergoing primary shoulder arthroplasty with prior ipsilateral nonarthroplasty shoulder surgery is unknown. The aim of this study was to determine the incidence and predictors of positive cultures in these patients. METHODS: We performed a retrospective review of patients with prior ipsilateral shoulder surgery with intraoperative cultures taken at the time of primary shoulder arthroplasty. We evaluated culture results, demographics, and number of prior surgeries. Regression analysis was used to determine patient-related risk factors that predict positive cultures. RESULTS: A total of 682 patients underwent primary shoulder arthroplasty, 83 had at least 1 prior ipsilateral shoulder surgery: 65.1% male, mean age 64.2 ± 10.9 years. For the cohort of 83 patients, an average of 3.2 ± 1.2 tissue samples were obtained for each patient, with a mean of 0.84 ± 1.14 tissue cultures being positive (range 0-5). Thirty-seven of the 83 patients (44.5%) had at least 1 positive culture, with Cutibacterium acnes the most frequent organism (31/37; 83.4%). An average of 1.9 ± 0.96 tissue cultures resulted positive (range 1-5) for the 37 patients who had positive cultures, 40.5% (15/37) had only 1 positive tissue culture (12/15 C acnes, 2/15 Staphylococcus epidermidis, and 1/15 vancomycin-resistant enterococcus). Male sex and history of prior shoulder infection were predictive of culture positivity (odds ratios: 2.5 and 20.9, respectively). Age, race, medical comorbidities, number of prior shoulder surgeries, and time from index shoulder surgery were not predictive of culture positivity. CONCLUSION: About 45% of patients with no clinical signs of infection and a history of prior ipsilateral shoulder surgery undergoing primary shoulder arthroplasty grew positive intraoperative cultures. The significance of these findings remains unclear with regard to risk of periprosthetic infection and how these patients should be managed.

Long-term Outcomes Following Vickers Ligament Release and Growth Modulation for the Treatment of Madelung Deformity.

BACKGROUND: Madelung deformity arises from a partial distal radial growth disturbance in combination with an abnormal hypertrophic ligament spanning the volar radius and carpus, termed, the Vickers ligament. The purpose of this study is to report long-term clinical and radiographic outcomes following Vickers ligament release and distal radial physiolysis in a population of skeletally immature patients with symptomatic Madelung deformity. METHODS: Medical records were retrospectively reviewed of patients with Madelung deformity surgically treated between 1994 and 2005. All eligible patients who underwent a Vickers ligament release and distal radial physiolysis were contacted and invited to return to the clinic for follow-up. RESULTS: Six patients (8 wrists) with Madelung deformity underwent Vickers ligament release and distal radial physiolysis. All were white females with a mean age at initial presentation of 11.4 years (10 to 12.8 y). Mean age at the time of initial surgery was 12.0 years (10.0 to 14.5 y). The median follow-up time was 10.6 years (5.8 to 21.9 y) and the average age at last follow-up was 23.1 years (17.5 to 32.2 y). Pain alone or in combination with concerns for deformity was the chief complaint in 6 of 8 of the wrists. At 1 year of clinical follow-up, 7 of 8 wrists were reported to be pain-free, and 6 of the 8 were noted to be completely pain-free at last follow-up. Motion in flexion, extension, pronation, supination, radial, or ulnar deviation was similar between the preoperative status and long-term follow-up. The average preoperative ulnar tilt was 35.1 degrees (SD: 8.5 degrees), average preoperative lunate subsidence was 1.9 degrees (SD: 1.8 degrees), and average preoperative palmar carpal displacement was 21.9 degrees (SD: 2.9 degrees). At the final follow-up, there was a large progression in lunate subsidence, but minimal change in ulnar tilt and palmar carpal displacement. At last clinical follow-up, 2 of the 6 patients had undergone a subsequent procedure including 1 radial dome osteotomy and 1 ulnar shortening osteotomy. CONCLUSION: In the skeletally immature patient population with Madelung deformity with growth potential remaining, distal radial physiolysis and Vickers ligament release is associated with relief of pain, preservation of motion, and, a reasonable rate of reoperation. TYPE OF STUDY: This was a therapeutic study. LEVEL OF EVIDENCE: Level II.

Clinical and Radiographic Outcomes of Femoral Head Fractures Associated with Traumatic Hip Dislocations.

BACKGROUND: Femoral head fractures are an uncommon but severe injury. These high-energy injuries typically occur in association with traumatic hip dislocations. Initial treatment includes urgent concentric reduction; however, controversy exists regarding specific fracture management. The well-known complications of avascular necrosis (AVN), posttraumatic arthritis (PTA), and heterotrophic ossification can leave patients with a significant functional loss of their affected hip. The purpose of this study is to evaluate the clinical and radiographic outcomes of femoral head fractures. METHODS: A retrospective review was performed at our institution assessing all patients who presented from 2007 to 2015 with a femoral head fracture associated with a hip dislocation and at least 6 months of clinical and radiographic follow-up. Twenty-two patients met our inclusion criteria. There were 15 males and 7 females with an average age of 36 years (range: 17-55). The average follow-up time was 18 months (range: 6-102). Fractures were classified according to the Pipkin classification. The Thompson and Epstein score was used to determine functional outcomes. RESULTS: There were five, Pipkin I, 3 Pipkin II, 0 Pipkin III, and 14 Pipkin IV, femoral head fractures. Sixteen patients were successfully closed reduced in the emergency department (ED) and six patients required open reduction after failed reduction in the ED. Four patients (18%) were successfully treated with closed reduction alone and 18 patients (82%) required operative intervention. Of those undergoing operative intervention, one patient underwent excision of the femoral head fragment, seven underwent open reduction internal fixation (ORIF) of the femoral head, nine underwent ORIF of the acetabulum, and one underwent ORIF of the femoral head and the acetabulum. Nine patients (41%) had an uneventful postoperative course. Two patients (9%) developed AVN, both requiring total hip arthroplasty (THA). Five patients (23%) developed PTA, two eventually requiring a THA. Two patients (9%) had sciatic nerve palsy. One patient (5%) developed a postoperative infection and four patients (18%) developed heterotrophic ossification (HO), none requiring operative treatment. Two patients (9%) had persistent anterolateral (AL) thigh numbness. Overall functional results were excellent in six patients (27%), good in six (27%), fair in seven (32%), and poor in three patients (14%). Four patients (18%) required a THA. CONCLUSION: Femoral head fractures are a rare injury with well-known complications. Early diagnosis and concentric reduction are the prerequisites for successful treatment. This study adds to the growing literature on femoral head fractures associated with hip dislocations in efforts to define treatment plans and to guide patient expectations.

Gender Differences on SF-36 Patient-Reported Outcomes of Diabetic Foot Disease.

The primary aim of this study was to evaluate the impact of gender on health-related quality of life (HRQOL) using a generic (Short Form-36 [SF-36]) and region-specific (Foot and Ankle Ability Measure [FAAM]) health measurement tool among a matched cohort of male and female patients with diabetes-related foot complications. The HRQOL of 240 patients with diabetic foot disease was measured using the SF-36 and the FAAM surveys. A total of 120 male patients were matched with 120 female patients with the same primary diagnosis, age, type, and duration of diabetes and insulin use. The SF-36 physical component summary (PCS) and mental component summary (MCS) scores were calculated using orthogonal and oblique rotation methods. The median age of the respondents was 54 years (interquartile range = 46-61). No differences in patient characteristics were found between genders. Among the SF-36 subscales, women reported significantly worse physical function ( P = .014) and bodily pain ( P = .021) scores with a trending decrease in general health score ( P = .067). Subsequently, women had worse orthogonal ( P = .009) and oblique PCS scores ( P = .036) than men. However, orthogonal ( P = .427) or oblique ( P = .140) MCS scores did not differ between groups. No significant differences in FAAM scores with respect to gender were appreciated. Our findings suggest that in patients with diabetic foot disease, women tend to report lower physical HRQOL compared with men. In efforts to increase compliance, providers should recognize the impact of gender on patients' perceptions of foot-related complications of diabetes. This knowledge may improve outcomes by adapting more individualized and gender-specific approaches to patients.

Meta-analysis of Randomized Controlled Trials on Patent Foramen Ovale Closure Versus Medical Therapy for Secondary Prevention of Cryptogenic Stroke.

The optimal management of patients with cryptogenic stroke (CS) and patent foramen ovale (PFO) remains controversial. We conducted a meta-analysis to assess the effect of PFO closure for secondary prevention of stroke on patients with CS. We searched the literature for randomized control trials assessing the recurrence of stroke after PFO closure compared with medical therapy (antiplatelet and/or anticoagulation). Five randomized control trials with a total of 3,440 patients were included. The mean age was 45.2 ± 9.7 years and follow-up duration ranged from 2.0 to 5.9 years. PFO closure significantly reduced the risk of stroke compared with the medical therapy (2.8% vs 5.8%; relative risk [RR] 0.48, confidence interval [CI] 0.27 to 0.87, p = 0.01, I2 = 56%). The number needed to treat for stroke prevention was 10.5. PFO closure was associated with an increased risk of atrial fibrillation compared with medical therapy (4.2% vs 0.7%; RR 4.55, CI 2.16 to 9.6, p = 0.0001, I2 = 25%). There was no significant difference in all-cause mortality (RR 1.33, CI 0.56 to 3.16, p = 0.52, I2 = 0%), as well as no difference in bleeding risk between the 2 groups (RR 0.94, CI 0.49 to 1.83, p = 0.86, I2 = 29%). In conclusion, our meta-analysis demonstrates that PFO closure is associated with significantly lower risk of recurrent stroke in patients with PFO and CS compared with medical therapy. However, atrial fibrillation was more common among closure patients.

Scoring Mental Health Quality of Life With the SF-36 in Patients With and Without Diabetes Foot Complications.

The aim of this study was to examine if using orthogonal and oblique factor analysis detect changes in health-related quality of life differently in diabetic patients on the Short Form-36 (SF-36) survey. A total of 155 patients had diabetic foot complications (DFC), and 145 patients had no DFCs. The SF-36 Physical Component Summary (PCS) and Mental Component Summary (MCS) scores were calculated using scoring coefficients determined by orthogonal and oblique rotation principle component analyses of the subscales. The DFC group had lower orthogonal ( P < .00001) and oblique PCS scores ( P < .00001). However, despite lower Mental Health subscale scores in the patients with DFCs, orthogonal MCS scores ( P = .156) did not differ. In contrast, the oblique MCS scores reflected the difference in the Mental Health subscale ( P = .0005). Orthogonal and oblique PCS scores did not differ significantly. However, orthogonal MCS scores were significantly higher than oblique MCS scores in those with DFCs ( P = .0004) and without DFCs ( P = .005). The shorter, 12-item SF-12 survey demonstrated similar results. Poorer physical function leads to higher orthogonal MCS scores than if determined by oblique scoring coefficients since Physical Function, Bodily Pain, and General Health are weighted more negatively in orthogonal coefficients when calculating the MCS score. Oblique scoring coefficients may address this issue, but further study is necessary to confirm whether oblique MCS scores accurately represent the mental health of patients with diabetic foot disease.

Functional Outcomes After Operative Treatment of Calcaneal Fractures: Midterm Review.

The purpose of this article is to report midterm follow-up of operatively treated calcaneus fractures. All patients with a calcaneus fracture, treated with open reduction and internal fixation (ORIF) using the extensile lateral approach, were identified. Functional outcomes were assessed using the American Orthopaedic Foot and Ankle Society's (AOFAS) ankle-hindfoot assessment, SF-36, and a questionnaire. There were 20 patients (25 fractures): 16 males and four females. The average age was 42 years (range, 16-73 years) and the mean follow-up time was 40 months (range, 13-73 months). The mean AOFAS score was 67.8 (SD = 19.3) and the mean SF-36 score was 55.7 (SD = 26.3). Patients in an motor vehicle accident had more associated injuries. Statistically significantly worse AOFAS scores were noted in patients with ORIF > 21 days after their injury (p = .047). Many lifestyle alterations were found to be present, including change in work, participation in recreational activities, footwear, and use of ambulatory assistive devices.

Vitamin D Supplementation Reduces Intimal Hyperplasia and Restenosis following Coronary Intervention in Atherosclerotic Swine.

Vitamin D is a fat-soluble steroid hormone that activates vitamin D receptor to regulate multiple downstream signaling pathways and transcription of various target genes. There is an association between vitamin D deficiency and increased risk for cardiovascular disease. However, most of the studies are observational and associative in nature with limited data on clinical application. Thus, there is a need for more prospective randomized controlled studies to determine whether or not vitamin D supplementation provides cardiovascular protection. In this study, we examined the effects of the deficiency and supplementation of vitamin D on coronary restenosis following coronary intervention in atherosclerotic Yucatan microswine. Twelve Yucatan microswine were fed vitamin D-deficient (n = 4) or -sufficient (n = 8) high cholesterol diet for 6-months followed by coronary intervention. Post-intervention, swine in the vitamin D-sufficient high cholesterol diet group received daily oral supplementation of either 1,000 IU (n = 4) or 3,000 IU (n = 4) vitamin D3. Six months later, optical coherence tomography (OCT) was performed to monitor the development of intimal hyperplasia and restenosis. Animals were euthanized to isolate arteries for histomorphometric and immunohistochemical studies. Animals had graded levels of serum 25(OH)D; vitamin D-deficient (15.33 ± 1.45 ng/ml), vitamin D-sufficient + 1,000 IU oral vitamin D post-intervention (32.27 ± 1.20 ng/ml), and vitamin D-sufficient + 3,000 IU oral vitamin D post-intervention (51.00 ± 3.47 ng/ml). Findings from the OCT and histomorphometric studies showed a decrease in intimal hyperplasia and restenosis in vitamin D-supplemented compared to vitamin D-deficient swine. Vitamin D supplementation significantly decreased serum levels of TNF-α and IFN-γ, upregulated serum levels of IL-10, and had no effect on serum IL-6 levels. These findings suggest that vitamin D supplementation limits neointimal formation following coronary intervention in atherosclerotic swine and provide the support for vitamin D supplementation to protect against the development of coronary restenosis.
