Mind the Difference: Characterizing the Impact of Behavioral Health Disorders on Facial Trauma.

BACKGROUND: Patients with psychiatric diagnoses are at greater risk for traumatic injury than the general population. Current literature fails to characterize how premorbid behavioral health disorders (BHDs) complicate craniofacial trauma. This study aimed to describe the characteristics and outcomes of patients with premorbid BHD sustaining facial fractures. METHODS: All adults in the 2013-2016 Trauma Quality Improvement Program datasets with facial fractures were identified. Demographics, injury characteristics, fracture patterns, and in-hospital outcomes were compared in patients with and without premorbid BHDs. BHDs included major psychiatric illnesses, alcohol or drug use disorders, attention deficit hyperactivity disorder, or dementia. RESULTS: Twenty-five percent of the 240,104 subjects with facial fractures had at least one premorbid BHD. Assault (29.9% versus 23.9%, P< 0.001), self-inflicted injury (2.9% versus 1.2%, P< 0.001), and multiple facial fractures (40.2% versus 38.7%, P< 0.001) were more common among the BHD group. The BHD group displayed significantly higher rates of nearly all in-hospital complications, including pneumonia (4.3% versus 3.3%, P< 0.001), substance withdrawal (3.9% versus 0.3%, P< 0.001), unplanned intubation (1.5% versus 0.9%, P< 0.001) and unplanned transfer to the intensive care unit (ICU, 1.3% versus 0.8%, P< 0.001). BHD was strongly predictive of pneumonia, unplanned intubation, and unplanned ICU admission in multivariate analyses. CONCLUSIONS: Patients with BHD represent a subset of facial trauma characterized by different mechanisms and patterns of injury and premorbid health status. BHDs are associated with higher in-hospital complication rates and resource utilization. Understanding the relationship between craniofacial trauma and premorbid BHD creates opportunities to improve morbidity and resource utilization in this group.

Patterns in the Pandemic: Disproportionate Patient Burdens Among Regional Hospitals.

STUDY OBJECTIVE: To examine the distribution of hospitalized COVID-19 patients among adult acute care facilities in the Greater Philadelphia area and identify factors associated with hospitals carrying higher burdens of COVID-19 patients. METHODS: In this observational descriptive study, we obtained self-reported daily COVID-19 inpatient censuses from 28 large (>100 beds) adult acute care hospitals in the Greater Philadelphia region during the initial wave of the COVID-19 pandemic (March 23, 2020, to July 28, 2020). We examined hospitals based on their size, location, trauma certification, median household income, and reliance on public insurance. COVID-19 inpatient burdens (ie, beds occupied by COVID-19 patients), relative to overall facility capacity (ie, total beds), were reported and assessed using thresholds established by the Institute of Health Metrics and Evaluation to approximate the stress induced by different COVID-19 levels. RESULTS: Maximum (ie, peak) daily COVID-19 occupancy averaged 27.5% (SD 11.2%) across the 28 hospitals. However, there was dramatic variation between hospitals, with maximum daily COVID-19 occupancy ranging from 5.7% to 50.0%. Smaller hospitals remained above 20% COVID-19 capacity for longer (small hospital median 27.5 days [interquartile range {IQR}: 4 to 32]; medium hospital median 18.5 days [IQR: 0.5 to 37]; large hospital median 13 days [IQR: 6 to 32]). Trauma centers reached 20% capacity sooner (median 19 days [IQR: 16-25] versus nontrauma median 30 days [IQR: 20 to 128]), remained above 20% capacity for longer (median 31 days [IQR: 11 to 38]; nontrauma median 8 days [IQR: 0 to 30]), and had higher observed burdens relative to their total capacity (median 5.8% [IQR: 2.4% to 8.3%]; nontrauma median 2.5% [IQR: 1.6% to 2.8%]). Urban location was also predictive of higher COVID-19 patient burden (urban median 3.8% [IQR: 2.6% to 6.7%]; suburban median 2.2% [IQR: 1.5% to 2.8%]). Heat map analyses demonstrated that hospitals in lower-income areas and hospitals in areas of higher reliance on public insurance also exhibited substantially higher COVID-19 occupancy and longer periods of higher COVID-19 occupancy. CONCLUSION: Substantial discrepancies in COVID-19 inpatient burdens existed among Philadelphia-region adult acute care facilities during the initial COVID-19 surge. Trauma center status, urban location, low household income, and high reliance on public insurance were associated with both higher COVID-19 burdens and longer periods of high occupancy. Improved data collection and centralized sharing of pandemic-specific data between health care facilities may improve resource balancing and patient care during current and future response efforts.

Inflammatory signature in lung tissues in patients with combined pulmonary fibrosis and emphysema.

Background: The aetiology and inflammatory profile of combined pulmonary fibrosis and emphysema (CPFE) remain uncertain currently. Objective: We aimed to examine the levels of inflammatory proteins in lung tissue in a cohort of patients with emphysema, interstitial pulmonary fibrosis (IPF), and CPFE. Materials and methods: Explanted lungs were obtained from subjects with emphysema, IPF, CPFE, (or normal subjects), and tissue extracts were prepared. Thirty-four inflammatory proteins were measured in each tissue section. Results: The levels of all 34 proteins were virtually indistinguishable in IPF compared with CPFE tissues, and collectively, the inflammatory profile in the emphysematous tissues were distinct from IPF and CPFE. Moreover, inflammatory protein levels were independent of the severity of the level of diseased tissue. Conclusions: We find that emphysematous lung tissues have a distinct inflammatory profile compared with either IPF or CPFE. However, the inflammatory profile in CPFE lungs is essentially identical to lungs from patients with IPF. These data suggest that distinct inflammatory processes collectively contribute to the disease processes in patients with emphysema, when compared to IPF and CPFE.

Orthopaedic Physician Attire Influences Patient Perceptions in an Urban Inpatient Setting.

BACKGROUND: Prior research suggests that physician attire has an important effect on patient perceptions, and can influence the patient-physician relationship. Previous studies have established the effect of specialty, location, and setting on patient preferences for physician attire, and the importance of these preferences and perceptions on both the physician-patient relationship and first impressions. To date, no studies have examined the influence of attire in the inpatient orthopaedic surgery setting on these perceptions. QUESTIONS/PURPOSES: (1) Do differences in orthopaedic physician attire influence patient confidence in their surgeon, perception of trustworthiness, safety, how caring their physician is, how smart their surgeon is, how well the surgery would go, and how willing they are to discuss personal information with the surgeon? (2) Do patients perceive physicians who are men and women differently with respect to those endpoints? METHODS: Ninety-three of 110 patients undergoing orthopaedic surgery at an urban academic medical center participated in a three-part survey. In the first part, each patient was randomly presented 10 images of both men and women surgeons, each dressed in five different outfits: business attire (BA), a white coat over business attire (WB), scrubs alone (SA), a white coat over scrubs (WS), and casual attire (CA). Respondents rated each image on a five-point Likert scale regarding how confident, trustworthy, safe, caring, and smart the surgeon appeared, how well the surgery would go, and the patient's willingness to discuss personal information with the surgeon. In the second part, the respondent ranked all images, by gender, from the most to least confident based on attire. RESULTS: Pair-wise comparisons for women surgeons demonstrated no difference in patient preference between white coat over business attire compared with white coat over scrubs or scrubs alone, though each was preferable to business attire and casual attire (WS versus WB: mean difference [MD], 0.1 ± 0.6; 95% CI, 0.0-0.2; p = 1.0; WS versus SA: MD, 0.2 ± 0.7; 95% CI, 0-0.3; p = 0.7; WB versus SA: 0.1 ± 0.9; 95% CI, -0.1 to 0.2; p = 1.0). The same results were found when rating the surgeon's perceived intelligence, skill, trust, confidentiality, caring, and safety. In the pair-wise comparisons for male surgeons, white coat over scrubs was not preferred to white coat over business attire, scrubs alone, or business attire (WS versus WB: MD, -0.1 ± 0.6; 95% CI, 0-0.1; p = 1.0; WS versus SA: MD, 0 ± 0.4; 95% CI, -0.2 to 0; p = 1.0; WS versus BA: MD, 0.2 ± 0.8; 95% CI, 0-0.4; p = 0.6). WB and SA were not different (MD, 0.0 ± 0.6; 95% CI, -0.1 to 0.2; p = 1.0), though both were preferred to BA and CA (WB versus BA: MD, 0.3 ± 0.8; 95% CI, 0.1-0.5; p = 0.02; WB versus CA: 1.0 ± 1.0; 95% CI, 0.8-1.2; p < 0.01). We found no difference between SA and BA (MD, 0.3 ± 0.7; 95% CI, 0.1-0.4; p = 0.06). We found that each was preferred to CA (SA versus CA: 0.9 ± 1.0; 95% CI, 0.7-1.2; p < 0.01; BA versus CA: 0.7 ± 1.0; 95% CI, 0.5-0.9; p < 0.01), with similar results in all other categories. When asked to rank all types of attire, patients preferred WS or WB for both men and women surgeons, followed by SA, BA, and CA. CONCLUSIONS: Similar to findings in the outpatient orthopaedic setting, in the inpatient setting, we found patients had a moderate overall preference for physicians wearing a white coat, either over scrubs or business attire, and, to some extent, scrubs alone. Respondents did not show any difference in preference based on the gender of the pictured surgeon. For men and women orthopaedic surgeons in the urban inpatient setting, stereotypical physician's attire such as a white coat over either scrubs or business attire, or even scrubs alone may improve numerous components of the patient-physician relationship and should therefore be strongly considered to enhance overall patient care. LEVEL OF EVIDENCE: Level II, therapeutic study.

Effect of Bifidobacterium infantis 35624 (Align) on the Lactulose Breath Test for Small Intestinal Bacterial Overgrowth.

BACKGROUND: Small intestinal bacterial overgrowth (SIBO) may cause symptoms in patients with abdominal bloating, distension, and gas. SIBO can be assessed using the lactulose breath test (LBT). A commonly used probiotic supplement is Align containing Bifidobacterium infantis 35624. The aim of this study was to determine the effect of B. infantis 35624 on hydrogen and methane excretion during LBT. METHODS: Healthy subjects underwent LBT before and after 2 weeks of daily Align administration. Hydrogen and methane concentrations were measured for each breath sample. Results are expressed as mean ± SE and analyzed using repeated measures ANCOVA. A breath test was considered positive if hydrogen and/or methane increased > 20 ppm above baseline by 90 min of the test or if a dual hydrogen peak was present. RESULTS: Nineteen healthy subjects were studied. Hydrogen levels were similar pre- and post-probiotic across the 3-h study (p = 0.768). In contrast, methane levels were significantly higher with probiotic administration (p = 0.012). A rise in methane > 20 ppm was seen in three subjects pre-probiotic but six post-probiotic. Of the 19 subjects, an "abnormal" LBT pre-probiotic was present in ten subjects and during the probiotic, 13 were abnormal. CONCLUSIONS: This study found that 2 weeks of B. infantis 35624 (Align) supplementation affects LBT assessment for SIBO by significantly increasing methane, but not hydrogen, excretion after lactulose administration. Methane levels reached values that would be considered positive for SIBO patients. This study suggests that patients undergoing LBT should discontinue probiotics prior to the test as these supplements may alter the test results.

Activation and polarization of circulating monocytes in severe chronic obstructive pulmonary disease.

BACKGROUND: The ability of circulating monocytes to develop into lung macrophages and promote lung tissue damage depends upon their phenotypic pattern of differentiation and activation. Whether this phenotypic pattern varies with COPD severity is unknown. Here we characterize the activation and differentiation status of circulating monocytes in patients with moderate vs. severe COPD. METHODS: Blood monocytes were isolated from normal non-smokers (14), current smokers (13), patients with moderate (9), and severe COPD (11). These cells were subjected to analysis by flow cytometry to characterize the expression of activation markers, chemoattractant receptors, and surface markers characteristic of either M1- or M2-type macrophages. RESULTS: Patients with severe COPD had increased numbers of total circulating monocytes and non-classical patrolling monocytes, compared to normal subjects and patients with moderate COPD. In addition, while the percentage of circulating monocytes that expressed an M2-like phenotype was reduced in patients with either moderate or severe disease, the levels of expression of M2 markers on this subpopulation of monocytes in severe COPD was significantly elevated. This was particularly evident for the expression of the chemoattractant receptor CCR5. CONCLUSIONS: Blood monocytes in severe COPD patients undergo unexpected pre-differentiation that is largely characteristic of M2-macrophage polarization, leading to the emergence of an unusual M2-like monocyte population with very high levels of CCR5. These results show that circulating monocytes in patients with severe COPD possess a cellular phenotype which may permit greater mobilization to the lung, with a pre-existing bias toward a potentially destructive inflammatory phenotype.

Postoperative Loss of Midline Function in Brachial Plexus Birth Palsy.

PURPOSE: To identify the rate of and predictive variables for functionally limited shoulder internal rotation in postoperative patients with brachial plexus birth palsy. METHODS: Records of patients with brachial plexus birth palsy who had surgery on the affected upper extremity during a 10-year period were retrospectively reviewed. Patient demographics, physical examinations, and all upper extremity procedures were recorded. Loss of midline function (LOM) was defined as a Modified Mallet Scale or Active Movement Scale (AMS) internal rotation score <3. Exclusion criteria were <1-year follow-up after the most recent procedure, insufficient documentation, or preexisting LOM. Multivariable logistic regression was performed on 3 different scenarios of candidate variables to identify those associated with LOM. All scenarios included each procedure as a candidate variable. Scenario A additionally analyzed preprocedural AMS scores. Scenario B additionally analyzed preprocedural Modified Mallet Scale scores. Scenario C isolated the surgical pathway without preprocedural examination scores. RESULTS: Among 172 included patients, 34 (19.8%) developed LOM. Predictive variables associated with LOM included severity of initial palsy (C5-7, odds ratio 3.6; C5-T1, odds ratio 4.9), poor recovery of upper trunk motor function before the patient's first surgery (specifically Modified Mallet Scale abduction < 4, AMS elbow flexion < 3, and AMS wrist extension < 3), and patients who ultimately required surgical glenohumeral reduction (odds ratio 3.6). Age, number of procedures, closed shoulder reduction with casting, shoulder tendon transfers, and external rotation humeral osteotomies were not predictive of LOM. CONCLUSIONS: Approximately 1 in every 5 patients with brachial plexus birth palsy will develop LOM after entering a surgical algorithm designed to improve shoulder external rotation. Patients with a more severe initial palsy (C5-7 or global), poor spontaneous recovery of upper trunk motor function (elbow flexion or wrist extension) before their first procedure, and those who ultimately require surgical glenohumeral joint reduction should be counseled as having a higher odds of LOM development. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

The Burdens, Concerns, and Quality of Life of Patients with Gastroparesis.

AIMS: The impact of gastroparesis on patients from the patient's viewpoint is needed to better address treatment priorities. The aims of this study were to: (1) Delineate burdens and concerns of patients with gastroparesis; (2) investigate specific symptoms contributing to impaired quality of life (QOL) in gastroparesis. METHODS: The International Foundation for Functional GI Disorders gastroparesis survey questionnaire was developed to describe patients' viewpoint about their experience with gastroparesis and included Patient Assessment of Upper GI Symptoms (PAGI-SYM) and SF-36 QOL survey. RESULTS: A total of 1423 adult patients with gastroparesis completed the survey. Average duration of gastroparesis symptoms was 9.3 years with time from onset to diagnosis 5.0 years. Patients felt that they receive good information regarding treatment options from physicians, the Internet, and Facebook. Patients rated their satisfaction with available treatment for their gastroparesis as dissatisfied (33%), somewhat dissatisfied (27%), neutral (14%), somewhat satisfied (15%), and satisfied (4%). Patients felt that gastroparesis symptoms that are most important to improve with treatment are nausea, stomach pain, and vomiting. Overall, there was a decreased quality of life by SF-36. Physical health QOL score was negatively correlated with symptoms including nausea (r = -0.37), upper abdominal pain (r = -0.37), and early satiety (r = -0.37). CONCLUSIONS: This large series of patients with gastroparesis describes their burdens, concerns, and QOL. Nausea, vomiting, early satiety, and abdominal pain are important symptoms for treatment. Many patients are not satisfied with current treatments, wanting specific treatments for their disorder. Interestingly, a large number of patients find out about treatments, not only from their physician, but also using the Internet including social media.

Physicians' Attire Influences Patients' Perceptions in the Urban Outpatient Orthopaedic Surgery Setting.

BACKGROUND: Previous work has established that physician attire influences patients' perceptions of their physicians. However, research from different specialties has disagreed regarding what kinds of physician attire might result in increased trust and confidence on the part of patients. QUESTIONS/PURPOSES: The purpose of this study was to investigate how surgeon attire affects patients' perceptions of trust and confidence in an urban orthopaedic outpatient setting. METHODS: Eighty-five of 100 patients solicited completed a three-part questionnaire in the outpatient orthopaedic clinic at an urban teaching hospital. In the first section, participants viewed eight images, four of a male surgeon and four of a female surgeon wearing a white coat over formal attire, scrubs, business attire, and casual attire, and rated each image on a five-level Likert scale. Participants were asked how confident, trustworthy, safe, caring, and smart the surgeon appeared, how well the surgery would go, and how willing they would be to discuss personal information with the pictured surgeon. The participant ranked all images from most to least confident in the second part and the last section obtained demographic information from the patients. Surveys were scored using a five-level Likert scale and a Friedman test was used to detect statistical significance when comparing all attires. For multiple pairwise comparisons, a Bonferroni correction was applied. RESULTS: The white coat on the male surgeon elicited modestly higher ratings in confidence (mean difference [MD], 0.367 ± 0.737; 95% CI, 0.202-0.532; p < 0.001), intelligence (MD, 0.216 ± 0.603; 95% CI, 0.077-0.356; p = 0.027), surgical skill (MD, 0.325 ± 0.658; 95% CI, 0.175-0.474; p < 0.001), trust (MD, 0.312 ± 0.613; 95% CI, 0.173-0.451; p < 0.001), ability to discuss confidential information (MD, 0.253 ± 0.742; 95% CI, 0.087-0.419; p = 0.023), caring (MD, 0.279 ± 0.655; 95% CI, 0.124-0.432; p = 0.006), and safety (MD, 0.260 ± 0.594; 95% CI, 0.125-0.395; p = 0.002) compared with business attire. Similarly, the white coat was preferred to casual attire in all categories (confidence: MD, 0.810 ± 0.921; smart: MD, 0.493 ± 0.801; surgical skill: MD, 0.640 ± 0.880; ability to discuss: MD, 0.564 ± 0.988; trust: MD, 0.545 ± 0.836; safety: MD, 0.581 ± 0.860; caring: MD, 0.479 ± 0.852; p < 0.001 for all comparisons). For the female surgeon, white coat and scrubs were not different, however the white coat was preferred to business attire in four of seven categories. Casual clothing was widely disliked in all categories for surgeons (men and women). When attire was compared for confidence on a scale, the white coat ranked higher than business (MD, 0.439 ± 1.491; p = 0.006) and casual attire (MD, 1.043 ± 2.054; p < 0.001), but not scrubs (MD, 0.169 ± 1.230; p = 1.000). CONCLUSIONS: In this urban outpatient orthopaedic practice, patients' preferences varied based on the sex of the pictured surgeon in the survey. Overall, however, modest preferences were observed for the white coat in terms of confidence, intelligence, trust, and safety. Furthermore patients are more willing to discuss personal information and believe that their surgery will go better if the surgeon wears a white coat or scrubs. These results are consistent with those of several studies in other settings and therefore may be generalizable in other locations and specialties. Given the increasing awareness and concern for physician-spread hospital infection, this study lends support to scrub attire over business or casual attire if physicians do not wear a white coat. LEVEL OF EVIDENCE: Level II, therapeutic study.

Utility of Routine Blood Cultures for Upper Extremity Abscesses.

BACKGROUND: Patients with skin and soft tissue infections (SSTIs) are often admitted by the emergency department for intravenous antibiotic therapy and surgical drainage of abscesses if necessary. As part of the initial diagnostic workup, blood cultures are routinely drawn at our institution in patients with SSTIs. This study seeks to identify the utility of performing blood cultures in patients with upper extremity abscesses as it relates to the number of incision and drainage (I&D) procedures performed, patient readmission rates, and length of hospital stay. METHODS: A retrospective chart review of 314 patients aged 18 to 89 years who underwent 1 or more I&D procedures of upper extremity abscesses were included in the study. Patient demographic data, comorbidities, laboratory values, wound and blood culture results, number of I&D procedures performed, length of stay, and readmission rates were evaluated. RESULTS: Increasing age and white blood count were associated with an increased number of I&Ds performed. Obtaining blood cultures, whether positive or negative, was associated with increased length of stay. There was no association between obtaining blood cultures and number of procedures performed on multivariable analysis. Positive blood cultures were associated with increased readmission rates. CONCLUSIONS: Routinely obtaining blood cultures in patients with upper extremity abscesses may not be beneficial. Obtaining blood cultures is not associated with an increased number of I&D procedures or readmission rates. Furthermore, obtaining blood cultures, regardless of positivity, is associated with increased lengths of hospital stay.

Six months after Maria: A post-hurricane examination of mental health and associated risk factors in older Puerto Ricans.

Following Hurricanes Irma and Maria in September 2017, there were elevated rates of depression and suicide in Puerto Rico. This study evaluates mental health in older and elderly Puerto Ricans 6 months after the hurricanes and suggests strategies for improving future psychosocial responses. Patients attending clinics were evaluated for depression (Patient Health Questionnaire [PHQ-9]) and suicide risk (Ask Suicide-Screening Questions [ASQ]) and were surveyed about their perceived safety, designated as a proxy for anxiety. Used in conjunction, PHQ-9 and ASQ were found to identify a greater proportion of individuals experiencing adverse mental health effects than if each instrument was used in isolation. Patients were also surveyed about time to water and electricity restoration, and it was found that prolonged time to water restoration was associated with increased prevalence and severity of depression and decreased perceived safety. Based on collected patient data (n = 523), using multiple mental health screening tools for diagnosis, improving perceptions of home safety or anxiety, and prioritizing water restoration may reduce mental health sequelae in the elderly and enhance the effect of psychosocial responses following disasters.

Outcomes of Implant Removal and Capsulectomy for Breast Implant Illness in 248 Patients.

BACKGROUND: Breast implant illness (BII) is a term popularized by social media to describe systemic symptoms that patients ascribe to their breast implants. Though the concept of implants as an underlying cause for a systemic illness remains controversial, few studies have delineated the implant characteristics, capsular histology, and outcomes of patients who undergo explantation for BII. METHODS: We retrospectively reviewed the demographics, presenting symptoms, outcomes, capsular histology, and culture results of all women who presented to the senior author with symptoms attributed to BII and underwent breast implant removal with capsulectomy from August 2016 to February 2020. Chi-square and logistic regression analyses were performed to evaluate association between implant type, composition, and findings of inflammation on capsule pathology. RESULTS: Among 248 patients, 111 (23%) capsules demonstrated inflammatory changes on permanent pathology. Capsular inflammation was independently associated with silicone versus saline (right odds ratio [OR] = 2.18 [1.16-4.11], P = 0.016, left OR = 2.35 [1.08-5.12], P = 0.03) and textured versus smooth implants (right OR = 2.18 [1.16-4.11], P = 0.016, left OR = 2.25 [1.17-4.31], P = 0.01). Silicone material was present in the capsules of 12 patients (4.8%). Fourteen patients had positive cultures. There was one pneumothorax (0.4%), three hematomas requiring evacuation (1%), and two DVTs (0.8%). Of 228 patients, 206 (90.4%) reported high satisfaction with the outcome of the procedure. CONCLUSIONS: In a large cohort of BII patients, we found that capsular inflammation is significantly associated with silicone and textured implants. Implant removal with capsulectomy can be safely performed in patients with BII with a low complication rate and high patient satisfaction.

Outcomes of Premature Ventricular Contraction-Cardiomyopathy in the Veteran Population: A Secondary Analysis of the CHF-STAT Study.

OBJECTIVES: This study sought to assess the rate and outcomes of premature ventricular contractions (PVC)-cardiomyopathy from the CHF-STAT (Survival Trial of Antiarrhythmic Therapy in Congestive Heart Failure) trial, a population with cardiomyopathy (left ventricular [LV] ejection fraction of <40%) and frequent PVCs (>10 PVCs per hour). BACKGROUND: PVCs are associated with heart failure and PVC-cardiomyopathy. The prevalence of PVC-cardiomyopathy and outcome benefits of PVC suppression are not clear. METHODS: A secondary analysis of the CHF-STAT study was performed to compare the rate of successful PVC suppression (≥80% PVC reduction), LV recovery (defined as improvement in LV ejection fraction of ≥10% points), and PVC-cardiomyopathy between amiodarone and placebo groups at 6 months. PVC-cardiomyopathy was defined if both PVC reduction of ≥80% and LV ejection fraction improvement of ≥10% were present at 6 months. Cardiac events (death or resuscitated cardiac arrest) were compared between PVC-cardiomyopathy versus non-PVC-cardiomyopathy during a 5-year follow-up. RESULTS: The rates of successful PVC suppression and LV recovery were significantly higher in the amiodarone (72% and 39%, respectively) when compared to the placebo group (12% and 16%, respectively; p < 0.001), regardless of cardiomyopathy etiology. PVC-cardiomyopathy was present in 29% and 1.8% of patients in the amiodarone and placebo groups, respectively (p < 0.001). Similar PVC-cardiomyopathy rates were found in ischemic (24% amiodarone vs. 2% placebo; p < 0.001) and nonischemic populations (41% amiodarone vs. 1.5% placebo; p < 0.001). Death and resuscitated cardiac arrest were significantly lower in patients with PVC-cardiomyopathy and those treated with amiodarone. CONCLUSIONS: The overall prevalence of PVC-cardiomyopathy in the CHF-STAT study was significant regardless of ischemic substrate (29%, overall population; 41%, nonischemic cardiomyopathy). Treatment of PVC-cardiomyopathy with amiodarone is likely to improve survival in this high-risk population.

Increasing Multidrug Antibiotic Resistance in MRSA Infections of the Hand: A 10-Year Analysis of Risk Factors.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) is the most common pathogen isolated from hand abscesses. The purpose of this study was to understand trends and changes in longitudinal antibiotic resistance profiles and risk factors for these infections to better guide empiric treatment of hand infections. Methods: We performed a retrospective review of culture-positive hand infections over a 10-year period at an urban academic institution from 2005 to 2014. A subset of MRSA hand infections from 2013 to 2014 was then subanalyzed for risk factors for antibiotic resistance for antibiotics with increasing antibiotic resistance during this period. Results: MRSA grew in 46% of hand infections, with a decreasing incidence over the 10-year study period. However, in the same time period clindamycin and levofloxacin resistance increased from 7% to 31% and 12% to 56%, respectively. Risk factors for clindamycin resistance included nosocomial infections and a history of intravenous drug use and hepatitis C. Risk factors for levofloxacin resistance included a history of diabetes and a fever upon initial presentation. Conclusions: The incidence of multidrug resistance remains high, with growing resistance to clindamycin and levofloxacin. There remains a trend for increased clindamycin resistance for patients with history of intravenous drug use and nosocomial infections. Our findings indicate that clindamycin and levofloxacin should be avoided for empiric treatment for hand infections in patients with these risk factors.

Why Not Life and Limb? Vasopressor Use in Intensive Care Unit Patients the Cause of Acute Limb Ischemia.

Background: Acute limb ischemia (ALI) of the upper extremity is a rare yet severe condition in intensive care unit (ICU) patients that generally leads to amputation. The aim of this study is to determine risk factors for development of upper extremity limb ischemia in ICU patients requiring vasopressor support. Methods: This is a retrospective study conducted from 2010 to 2015. Patients who received vasopressors during ICU admission were considered for the study. Patients were identified via Current Procedural Terminology (CPT) billing codes. ALI patients were matched to control patients based on diagnosis and Acute Physiology and Chronic Health Evaluation II score. Days on pressors, number of pressors, total doses, and level of ischemia were recorded. Primary end point was doses, types, and days on vasopressors. Secondary end point was level of ALI. Results: Patients in the ALI group were more likely to be started on a higher number of different types of pressors (2.6 vs 1.3 pressors). ALI patients received pressors for 8.5 days compared with 1.6 days in control patients, and received 12.8 doses compared with 3.0 doses in control patients. In addition, vasopressors with alpha-adrenergic activity were more likely to be used in the ALI group. Level of ischemia was not linked to any of the tested variables. Conclusion: Patients admitted to the ICU are more likely to sustain an acute ischemic event of an upper extremity with more vasopressor usage. Patients who received alpha-adrenergic activating vasopressors were more likely to sustain limb ischemia. When discoloration of an extremity is detected, patients should receive counteractive treatments in an effort to salvage the extremity and prevent function loss.

Patient Satisfaction in the Preoperative Period: Preparing for Hand Surgery.

Background: The potential impact of the number and type of preoperative encounters on satisfaction rates prior to elective surgical procedures is unclear, specifically scheduling and medical clearance encounters. Methods: Questionnaires investigating satisfaction with the preoperative process were collected for 200 patients presenting for elective hand surgery. The number of telephone, surgeon, and medical clearance encounters were recorded, and satisfaction was determined for each type based on a 4-category Likert scale. All patients 18 years or older were included, while only patients providing incomplete questionnaires were excluded. Outcome data were assessed for associations between different encounter totals or types and satisfaction rates. Results: Among 200 patients, 197 completed the questionnaire and were included. Overall satisfaction with the preoperative process was 92.9%, with only 3% of patients dissatisfied. There was a significant association between satisfaction and the number of telephone and total encounters. Satisfaction fell below 90% after 4 or more telephone calls (66.6%, P = 0.005) and 5 or more total encounters (80%, P = 0.008). When considered individually, there was no significant association between satisfaction and the number of surgeon (P = 0.267) or medical office encounters (P = 0.087), or a patient's perceived health status (P = 0.14). Conclusions: Greater than 3 telephone or 4 total encounters significantly decreases patient satisfaction, while surgeon and medical office visits are not associated with satisfaction rates when considered individually. This suggests the number, not the type, of preoperative encounters impact satisfaction and highlight the importance of efficient communication between patients and providers.

HIV and HCV screening among trauma patients.

The purpose of this study was to develop a hepatitis C virus (HCV) and HIV screening program for patients evaluated by the trauma service and link to care. Patients were offered screening for HCV antibody and HIV. Demographics were collected on gender, race, age, and history of intravenous drug use. A navigator connected patients to treatment. In total, 1160 trauma patients were screened for HCV and/or HIV. There were 162 (14%) patients with HCV antibodies. Patients who inject drugs comprised 39.5% (64) of the HCV antibody positive group. Forty-six (68.7%) patients received linkage to care services and 55 (34%) patients were actively engaged in treatment. There were 155 (10.5%) of all eligible patients screened for HIV. Twenty-one (13.5%) patients were living with HIV (PLWH) and there were two (1.3%) new HIV infections. All new PLWH were linked to care and a total of 14 (73.7%) PLWH were on antiretroviral therapy. This is the first HCV and HIV screening and linkage to care program of trauma surgery patients. In this interim program evaluation, we found high prevalence of HCV antibody and HIV prevalence and high linkage to care rates. Trauma service HCV and HIV screening is an opportunity to diagnose, link, and re-engage a vulnerable population.

Intragastric Meal Distribution During Gastric Emptying Scintigraphy for Assessment of Fundic Accommodation: Correlation with Symptoms of Gastroparesis.

Impaired fundic accommodation (FA) limits fundic relaxation and the ability to act as a reservoir for food. Assessing intragastric meal distribution (IMD) during gastric emptying scintigraphy (GES) allows for a simple measure of FA. The 3 goals of this study were to evaluate trained readers' (nuclear medicine and radiology physicians) visual assessments of FA from solid-meal GES; develop software to quantify GES IMD; and correlate symptoms of gastroparesis with IMD and gastric emptying. Methods: After training to achieve a consensus interpretation of GES FA, 4 readers interpreted FA in 148 GES studies from normal volunteers and patients. Mixture distribution and κ-agreement analyses were used to assess reader consistency and agreement of scoring of FA. Semiautomated software was used to quantify IMD (ratio of gastric counts in the proximal stomach to those in the total stomach) at 0, 1, 2, 3, and 4 h after ingestion of a meal. Receiver-operating-characteristic analysis was performed to optimize the diagnosis of abnormal IMD at 0 min (IMD0) with impaired FA. IMD0, GES, water load testing, and symptoms were then compared in 177 patients with symptoms of gastroparesis. Results: Reader pairwise weighted κ-values for the visual assessment of FA averaged 0.43 (moderate agreement) for normal FA versus impaired FA. Readers achieved 84.0% consensus and 85.8% reproducibility in assessing impaired FA. IMD0 based on the division of the stomach into proximal and distal halves averaged 0.809 (SD, 0.083) for normal FA and 0.447 (SD, 0.132) (P < 0.01) for impaired FA. On the basis of receiver-operating-characteristic analysis, the optimal cutoff for IMD0 discrimination of normal FA from impaired FA was 0.568 (sensitivity, 86.7%; specificity, 91.7%). Of 177 patients with symptoms of gastroparesis, 129 (72.9%) had delayed gastric emptying; 25 (14.1%) had abnormal IMD0 Low IMD0 (impaired FA) was associated with increased early satiety (P = 0.02). Conclusion: FA can be assessed visually during routine GES with moderate agreement and high reader consistency. Visual and quantitative assessments of FA during GES can yield additional information on gastric motility to help explain patients' symptoms.

Association of Variants in BAG3 With Cardiomyopathy Outcomes in African American Individuals.

Importance: The prevalence of nonischemic dilated cardiomyopathy (DCM) is greater in individuals of African ancestry than in individuals of European ancestry. However, little is known about whether the difference in prevalence or outcomes is associated with functional genetic variants. Objective: We hypothesized that Bcl2-associated anthanogene 3 (BAG3) genetic variants were associated with outcomes in individuals of African ancestry with DCM. Design: This multicohort study of the BAG3 genotype in patients of African ancestry with dilated cardiomyopathy uses DNA obtained from African American individuals enrolled in 3 clinical studies: the Genetic Risk Assessment of African Americans With Heart Failure (GRAHF) study; the Intervention in Myocarditis and Acute Cardiomyopathy Trial-2 (IMAC-2) study; and the Genetic Risk Assessment of Cardiac Events (GRACE) study. Samples of DNA were also acquired from the left ventricular myocardium of patients of African ancestry who underwent heart transplant at the University of Colorado and University of Pittsburgh. Main Outcomes and Measures: The primary end points were the prevalence of BAG3 mutations in African American individuals and event-free survival in participants harboring functional BAG3 mutations. Results: Four BAG3 genetic variants were identified; these were expressed in 42 of 402 African American individuals (10.4%) with nonischemic heart failure and 9 of 107 African American individuals (8.4%) with ischemic heart failure but were not present in a reference population of European ancestry (P < .001). The variants included 2 nonsynonymous single-nucleotide variants; 1 three-nucleotide in-frame insertion; and 2 single-nucleotide variants that were linked in cis. The presence of BAG3 variants was associated with a nearly 2-fold (hazard ratio, 1.97 [95% CI, 1.19-3.24]; P = .01) increase in cardiac events in carriers compared with noncarriers. Transfection of transformed adult human ventricular myocytes with plasmids expressing the 4 variants demonstrated that each variant caused an increase in apoptosis and a decrease in autophagy when samples were subjected to the stress of hypoxia-reoxygenation. Conclusions and Relevance: This study demonstrates that genetic variants in BAG3 found almost exclusively in individuals of African ancestry were not causative of disease but were associated with a negative outcome in patients with a dilated cardiomyopathy through modulation of the function of BAG3. The results emphasize the importance of biological differences in causing phenotypic variance across diverse patient populations, the need to include diverse populations in genetic cohorts, and the importance of determining the pathogenicity of genetic variants.
