Septic arthritis of native joints is uncommon, but the condition can be threatening to life and limb if left untreated.1 Septic arthritis of the acromioclavicular (AC) joint of the shoulder is particularly rare and has only appeared sparsely in medical literature, mainly through individual case reports. Early recognition and treatment of the condition is vital, but diagnosis of septic AC arthritis can be difficult due to its presentation with vague symptoms and nonspecific laboratory findings. This case report describes the care of a patient with poorly managed diabetes who presented to the emergency department with one month of pain and swelling of the left shoulder and two weeks of pain and swelling in the right ankle. Imaging revealed fluid in the AC joint, and laboratory evaluation showed an elevation in inflammatory markers, including leukocyte count, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR). The patient’s hospital course was complicated by methicillin-sensitive Staphylococcus Aureus bacteremia without evidence of sepsis. The patient underwent open debridement and washout of both the ankle and AC joint without complication. After recovery, the patient was discharged to a rehabilitative center with IV antibiotics and weekly follow up care with infectious disease specialists. This case illustrates the importance of early diagnosis and treatment of septic arthritis, even in less common joint spaces, to prevent progression of this dangerous disease.Topics: Septic arthritis, acromioclavicular joint, diabetes, bacteremia.

Background:. Reported drug allergies are commonly encountered by surgeons and can lead to uncertainty in selecting an appropriate agent due to concerns of associated risks with related and cross-reactive drugs. This uncertainty can ultimately lead to increased infection rates. Methods:. A literature review was conducted in PubMed using a combination of the terms “allergy,” “allergic reaction,” “anaphylaxis,” and “surgery,” “surgical,” or “operating room” for articles published within the last 10 years. Publications identified with these search terms were then filtered for review articles, sorted by “best match,” and a maximum of 100 articles were manually reviewed for each combination of search terms. Results:. Search results yielded 46,484 articles, 676 of which were ultimately included for manual review, based on selection criteria. Specifically, articles selected for inclusion focused on surgical allergic reactions that were either related to mechanism of action, causative agent for the allergic reaction, timing of allergic reaction, or recommendations for appropriate management. Conclusions:. Allergic reactions can be a common occurrence in the operative room. Knowledge of likely causative agents, timing of a reaction to various agents, and appropriate management in the immediate and delayed setting can improve outcomes and safety for plastic surgery patients.

Background:. Carbon monoxide (CO) is an endogenous signaling molecule that activates cytoprotective programs implicated in the resolution of acute respiratory distress syndrome (ARDS) and survival of critical illness. Because CO levels can be measured in blood as carboxyhemoglobin, we hypothesized that carboxyhemoglobin percent (COHb%) may associate with mortality. OBJECTIVES:. To examine the relationship between COHb% and outcomes in patients with ARDS requiring venovenous extracorporeal membrane oxygenation (ECMO), a condition where elevated COHb% is commonly observed. DESIGN:. Retrospective cohort study. SETTING:. Academic medical center ICU. PATIENTS:. Patients were included that had ARDS on venovenous ECMO. MEASUREMENTS AND MAIN RESULTS:. We examined the association between COHb% and mortality using a Cox proportional hazards model. Secondary outcomes including ECMO duration, ventilator weaning, and hospital and ICU length of stay were examined using both subdistribution and causal-specific hazard models for competing risks. We identified 109 consecutive patients for analysis. Mortality significantly decreased per 1 U increase in COHb% below 3.25% (hazard ratio [HR], 0.35; 95% CI, 0.15–0.80; p = 0.013) and increased per 1 U increase above 3.25% (HR, 4.7; 95% CI, 1.5–14.7; p = 0.007) reflecting a nonlinear association (p = 0.006). Each unit increase in COHb% was associated with reduced likelihood of liberation from ECMO and mechanical ventilation, and increased time to hospital and ICU discharge (all p < 0.05). COHb% was significantly associated with hemolysis but not with initiation of hemodialysis or blood transfusions. CONCLUSIONS:. In patients with ARDS on venovenous ECMO, COHb% is a novel biomarker for mortality exhibiting a U-shaped pattern. Our findings suggest that too little CO (perhaps due to impaired host signaling) or excess CO (perhaps due to hemolysis) is associated with higher mortality. Patients with low COHb% may exhibit the most benefit from future therapies targeting anti-oxidant and anti-inflammatory pathways such as low-dose inhaled CO gas.

BACKGROUND: Age is an important prognostic factor in breast cancer. The target age to screen is under debate. OBJECTIVE: This study aimed to assess the influence of age on the diagnosis and survival among women with breast cancer. STUDY DESIGN: This was a retrospective cohort study of the Population-Based Cancer Registry of Campinas, Brazil, and included all women diagnosed from 2010 to 2014. The outcomes assessed were overall survival and stage. For statistical analyses, the Kaplan-Meier method, log-rank tests, and chi-square tests were used. RESULTS: The sample comprised 1741 women aged 40 to 79 years. Diagnoses at stages 0 to II were the more frequent. In the 40 to 49 years and 50 to 59 years age groups, the frequency of stage 0 (in situ) was 20.5% and 14.9% (P=.022), respectively, and the frequency of stage I was 20.2% and 25.8% (P=.042), respectively. The mean overall survival was 8.9 years (8.6–9.2) in the 40 to 49 years age group and 7.7 years (7.3–8.1) in the 70 to 79 years age group. The 5-year overall survival was higher in the 40 to 49 years age group than in the 50 to 59 years age group for stage 0 (in situ) (100.0% vs 95.0%; P=.036) and stage III (77.4% vs 66.2%; P=.046) diagnoses. The 5-year overall survival was higher in 60 to 69 years age group than in the 70 to 79 years age group for stages I (94.6% vs 86.5%; P=.002) and III (83.5% vs 64.9%; P=.010). In all age groups, significant differences in survival were not observed for stage 0 (in situ) vs stage I diagnoses, stage 0 vs stage II diagnoses, and stage I vs stage II diagnoses. CONCLUSION: Women aged 40 to 49 years had the highest proportion of in situ tumors, and stages III and IV accounted for about one-third of the cases in all age groups. There was no difference in the overall survival for stage 0 (in situ) vs stage I or II diagnoses in all age groups.

The timing of initiating mechanical ventilation in patients with acute respiratory distress syndrome due to COVID-19 remains controversial. At the outset of the pandemic, “very early” intubation was recommended in patients requiring oxygen flows above 6 L per minute but was followed closely thereafter by avoidance of invasive mechanical ventilation (IMV) due to a perceived (yet over-estimated) risk of mortality after intubation. While the use of noninvasive methods of oxygen delivery, such as high-flow nasal oxygen (HFNO) or noninvasive positive pressure ventilation (NIV), can avert the need for mechanical ventilation in some, accumulating evidence suggests delayed intubation is also associated with an increased mortality in a subset of COVID-19 patients. Close monitoring is necessary in COVID-19 patients on HFNO or NIV to identify signs of noninvasive failure and ensure appropriate provision of IMV.

OBJECTIVES:. The COVID-19 pandemic has claimed over eight hundred thousand lives in the United States alone, with older individuals and those with comorbidities being at higher risk of severe disease and death. Although severe acute respiratory syndrome coronavirus 2–induced hyperinflammation is one of the mechanisms underlying the high mortality, the association between age and innate immune responses in COVID-19 mortality remains unclear. DESIGN:. Flow cytometry of fresh blood and multiplexed inflammatory chemokine measurements of sera were performed on samples collected longitudinally from our cohort. Aggregate impact of comorbid conditions was calculated with the Charlson Comorbidity Index, and association between patient factors and outcomes was calculated via Cox proportional hazard analysis and repeated measures analysis of variance. SETTING:. A cohort of severely ill COVID-19 patients requiring ICU admission was followed prospectively. PATIENTS:. In total, 67 patients (46 male, age 59 ± 14 yr) were included in the study. INTERVENTIONS:. None. MEASUREMENTS AND MAIN RESULTS:. Mortality in our cohort was 41.8%. We identified older age (hazard ratio [HR] 1.09 [95% CI 1.07–1.11]; p = 0.001), higher comorbidity index (HR 1.24 [95% CI 1.14–1.35]; p = 0.039), and hyponatremia (HR 0.90 [95% CI 0.82–0.99]; p = 0.026) to each independently increase risk for death in COVID-19. We also found that neutrophilia (R = 0.2; p = 0.017), chemokine C-C motif ligand (CCL) 2 (R = 0.3; p = 0.043), and C-X-C motif chemokine ligand 9 (CXCL9) (R = 0.3; p = 0.050) were weakly but significantly correlated with mortality. Older age was associated with lower monocyte (R = –0.2; p = 0.006) and cluster of differentiation (CD) 16+ cell counts (R = –0.2; p = 0.002) and increased CCL11 concentration (R = 0.3; p = 0.050). Similarly, younger patients (< 65 yr) demonstrated a rise in CD4 (b-coefficient = 0.02; p = 0.036) and CD8 (0.01; p = 0.001) counts, as well as CCL20 (b-coefficient = 6.8; p = 0.036) during their ICU stay. This CD8 count rise was also associated with survival (b-coefficient = 0.01; p = 0.023). CONCLUSIONS:. Age, comorbidities, and hyponatremia independently predict mortality in severe COVID-19. Neutrophilia and higher CCL2 and CXCL9 levels are also associated with higher mortality, while independent of age.

Background:. Atasoy flaps (AFs) are commonly used to reconstruct digits after fingertip injuries. However, recent literature reports that some surgeons prefer skeletal shortening and closure, presumably because the procedure can be performed in the emergency department without the risk of flap-associated complications. The purpose of the present outcome study is to evaluate patient-reported, long-term satisfaction of AF reconstructions for fingertip injuries. Methods:. Adult, male patients working in manual labor occupations who underwent AF reconstruction for fingertip injuries were identified from an institutional database. Patients were administered an injury-specific questionnaire relating to nail growth, function, aesthetics, cryalgia, and hypersensitivity. They were then administered the QuickDASH questionnaire to report standardized functional impairment and asked about their overall satisfaction with their reconstructed finger. Results:. Twelve patients underwent AF fingertip reconstruction between 2015 and 2020. Eleven of these patients agreed to be interviewed, the majority having been treated in the emergency department setting. The overall satisfaction rate was 91% (n = 10). Common sequelae included hook nail 64% (n = 7), cold sensitivity 45% (n = 5), and hypersensitivity 27% (n = 3). There were no flap failures or tissue necrosis. One patient reported a second surgery for improvement of a hook nail deformity. Conclusions:. Long-term outcomes of AF reconstruction for fingertip injuries demonstrate high overall satisfaction. Patients appreciated tissue salvage to preserve digit length, even in those unconcerned with aesthetics. Issues reported by patients, such as cold intolerance, hook nail, and decreased tactile sensation, are similar to other treatment options for fingertip injuries.

Background:. Deep sternal wound infection and mediastinitis following sternotomy are associated with significant morbidity and mortality, and often require sternal reconstruction by plastic surgeons. Despite this patient population having a substantial risk of venous thromboembolism, there are no reports of the incidence of venous thromboembolism in patients undergoing sternal reconstruction. The authors sought to evaluate the incidence of venous thromboembolism in sternal reconstruction patients and to identify common risk factors for venous thromboembolism in this patient population. Methods:. A single-center retrospective review was completed of all patients who underwent sternal reconstruction by plastic surgeons between January 2012 and July 2020. Demographic data, antiplatelet and anticoagulant use, 2005 Caprini score, operative time, bleeding events, and postoperative venous thromboembolism events were recorded. Results:. A total of 44 patients were identified for analysis. The average 2005 Caprini score for the cohort was 10.9. In total, 93.2% of patients received perioperative antiplatelet and anticoagulant therapy (either chemoprophylaxis or systemic). Two patients developed postoperative venous thromboembolism events, for a total venous thromboembolism rate of 4.6%. Four patients had bleeding events requiring reoperation. No deaths were reported from either of these complications. Conclusions:. Patients undergoing sternal reconstruction are at a high risk for venous thromboembolism and postoperative bleeding events. Despite the growing body of literature on venous thromboembolism in various surgical populations, the optimal management of thromboembolic risk in patients with high Caprini scores undergoing sternal reconstruction requires additional investigation.

Summary:. Pilonidal disease is a common problem across the globe, with a wide variety of options for management, ranging from healing by secondary intention to flap closure. As new techniques have been introduced, the ideal method to reduce complications and limit recurrence has become unclear. In this review, we highlight the most common methods used to treat pilonidal disease, as well as the senior author’s preferred technique for management. Ideally, surgeons are able to choose the optimal procedure for each patient and maximize outcomes with minimal patient care burden and morbidity.

Summary:. Panniculectomy is an increasingly common operation, given the current obesity epidemic and the increasing prevalence of bariatric surgery. At first glance, it could be considered a technically simple operation; however, this procedure can be fraught with complications, given the patient population and high demands placed on compromised abdominal tissue. Sufficient attention must be given to the nuances of patient optimization and surgical planning to maximize safe and ideal outcomes. We highlight our practical tips when performing standard or massive panniculectomy for preoperative optimization, intraoperative techniques, and postoperative management to reduce complication and maximize outcomes of this procedure from a surgeon’s and a patient’s perspective.

Summary: Post-mastectomy pain syndrome is a prevalent chronic pain condition that affects numerous patients following breast surgery. The mechanism of this pain has been proposed to be neurogenic in nature. As such, we propose a novel surgical method for the prophylactic management of postsurgical breast pain: targeted muscle reinnervation of the breast. This article serves to review the relevant current literature of post-mastectomy pain syndrome and targeted muscle reinnervation, describe our current surgical technique for this operation, and present an initial cohort of patients to undergo this procedure.

Recurrent urolithiasis is a common and potentially morbid complication of spina bifida. Although the size, the location, and the composition of these stones often necessitates percutaneous intervention, access is often complicated by body habitus and spinal deformity. There is little consensus regarding the approach to percutaneous lithotripsy when a clear path to the collecting system is unavailable, particularly in the setting of surgically augmented urological anatomy. Here we present the first known case in which a pediatric patient with spina bifida underwent percutaneous lithotripsy of bladder stones via a transpsoas approach.

Summary:. The inframammary fold (IMF) can be challenging to reconstruct after disruption during mastectomy or breast reconstruction. The Ryan procedure is a previously described technique with little long-term analysis. Our goal is to analyze the long-term results of the Ryan procedure using 3-dimensional (3D) technology, with the hypothesis that 3D measurements will provide quantitative outcomes that add to the qualitative assessment of the reconstruction. We retrospectively reviewed consecutive breast reconstruction patients by a single surgeon from January 1, 2012 to January 31, 2015 to identify patients who underwent the Ryan procedure. Previously obtained 3D photographs were then analyzed to compare breast base diameter, breast projection, and inter-IMF distance pre- and postoperatively. A survey was then given to 15 health professionals in our department to assess the IMF and symmetry pre- and postoperatively. Eight patients were eligible for inclusion. Four patients were unilateral reconstruction and 4 were bilateral. The Ryan procedure resulted in an inter-IMF discrepancy reduction of 39% and a breast projection increase of 18%. Average length of follow-up was 2.82 ± 0.75 years. One patient required a secondary IMF revision. The majority of survey respondents felt that the IMF and IMF symmetry were improved or stable postoperatively. The Ryan procedure seems to be a reliable and durable technique for IMF reconstruction with increased projection, decreased IMF discrepancy, and increased symmetry. Additionally, 3D imaging provides a useful approach in the assessment of breast reconstruction outcomes, adding quantitative outcomes measures to its evaluation.

Introduction: Ethanol has been used for years in neonatal and infant liquid medications, yet the pharmacokinetics, pharmacodynamics, and safety of ethanol in this vulnerable population have not been well characterized. The purpose of this review is to raise awareness of ethanol use as an excipient in neonatal and infant medications and to provide insight, based on the available evidence, into clearance rates of ethanol in babies. We also discuss ethanol pharmacokinetics in adults, theoretical pharmacokinetic changes in neonates and infants as it may apply to ethanol disposition, and case reports involving ethanol exposure in neonates and infants. Materials and methods: This study was a narrative review in which relevant papers were selected using databases and scientific search engines such as PubMed with the key words ethanol, infant, and newborn infant. Results: It remains unclear what ethanol exposure is safe for neonates and infants. The Food and Drug Administration and American Academy of Pediatrics have both taken action, by either setting limits of ethanol content in over-the-counter medications or by recommending restricted exposure to ethanol-containing pediatric formulations. Conclusions: Until the short- and long-term health effects of chronic ethanol administration can be further characterized, ethanol-containing medications should be used with caution.

The article presents an overview of standards for the nutritional support of adult hospital patients developed by the American Society for Parenteral and Enteral Nutrition, a professional society of physicians, nurses, dietitians, pharmacists, allied health professionals, and researchers which is dedicated to ensuring that all hospital patients receive optimal nutrition care. The standards are for all hospitals, regardless of whether they have a formal nutrition support service or not.

Purpose: To describe the perceptions of residency candidates, residency practitioners (current residents and preceptors), and residency program directors (RPDs) regarding a virtual interview process for pharmacy residency programs across multiple institutions., Methods: In May 2021, an anonymous web-based questionnaire characterizing perceptions of the virtual interview process used during the coronavirus disease 2019 (COVID-19) pandemic was distributed to residency candidates, residency practitioners, and RPDs across 13 institutions. Quantitative responses measured on a 5-point Likert scale were summarized with descriptive statistics, and open-ended questions were analyzed using thematic qualitative methods., Results: 236 residency candidates and 253 residency practitioners/RPDs completed the questionnaire, yielding response rates of 27.8% (236 of 848), and 38.1% (253 of 663), respectively. Overall, both groups perceived the virtual interview format positively. When asked whether virtual interviews should replace in-person interviews moving forward, 60.0% (18 of 30) of RPDs indicated they agreed or strongly agreed, whereas only 30.5% (61 of 200) of current preceptors/residents and 28.7% (66 of 230) of residency candidates agreed or strongly agreed. Thematic analysis of qualitative responses revealed that while virtual interviews were easier logistically, the lack of in-person interactions was a common concern for many stakeholders. Lastly, the majority (65.0%) of residency candidates reported greater than $1,000 in savings with virtual interviews., Conclusion: Virtual interviews offered logistical and financial benefits. The majority of RPDs were in favor of offering virtual interviews to replace in-person interviews, whereas the majority of residency candidates and practitioners preferred on-site interviews. As restrictions persist with the ongoing pandemic, our results provide insight into best practices for virtual pharmacy residency interviews., (© American Society of Health-System Pharmacists 2022.

Research is foundational for evidence-based management of patients. Clinical research, however, takes time to plan, conduct, and disseminate-a luxury that is rarely available during a public health emergency. The University of Nebraska Medical Center (UNMC) developed a single institutional review board (IRB), with a vision to establish a rapid review resource for a network focused on clinical research of emerging pathogens in the United States. A core aspect of successful initiation of research during a pandemic or epidemic is the ability to operationalize an approach for rapid ethical review of human subject research and conduct those reviews at multiple sites-without losing any of the substantive aspects of ethics review. This process must be cultivated in anticipation of a public health emergency. US guidance for operationalizing IRB review for multisite research in a public health emergency is not well studied and processes are not well established. UNMC sought to address operational gaps and identify the unique procedural needs of rapid response single IRB (RR-sIRB) review of multisite research by conducting a series of preparedness exercises to develop and test the RR-sIRB model. For decades, emergency responder, healthcare, and public health organizations have conducted emergency preparedness exercises to test requirements for emergency response. In this article, we describe 2 types of simulation exercises conducted by UNMC: workshops and tabletops. This effort represents a unique use of emergency preparedness exercises to develop, refine, and test rapid review functions for an sIRB and to validate readiness of regulatory research processes. Such processes are crucial for conducting rapid, ethical, and sound clinical research in public health emergencies.

Plastics have long been an environmental contaminant of concern as both large-scale plastic debris and as micro- and nano-plastics with demonstrated wide-scale ubiquity. Research in the past decade has focused on the potential toxicological risks posed by microplastics, as well as their unique fate and transport brought on by their colloidal nature. These efforts have been slowed by the lack of analytical techniques with sufficient sensitivity and selectivity to adequately detect and characterize these contaminants in environmental and biological matrices. To improve analytical analyses, microplastic tracers are developed with recognizable isotopic, metallic, or fluorescent signatures capable of being identified amidst a complex background. Here we describe the synthesis, characterization, and application of a novel synthetic copolymer nanoplastic based on polystyrene (PS) and poly(2-vinylpyridine) (P2VP) intercalated with gold, platinum or palladium nanoparticles that can be capped with different polymeric shells meant to mimic the intended microplastic. In this work, particles with PS and polymethylmethacrylate (PMMA) shells are used to examine the behavior of microplastic particles in estuarine sediment and coastal waters. The micro- and nanoplastic tracers, with sizes between 300 and 500 nm in diameter, were characterized using multiple physical, chemical, and colloidal analysis techniques. The metallic signatures of the tracers allow for quantification by both bulk and single-particle inductively-coupled plasma mass spectrometry (ICP-MS and spICP-MS, respectively). As a demonstration of environmental applicability, the tracers were equilibrated with sediment collected from Bellingham Bay, WA, United States to determine the degree to which microplastics bind and sink in an estuary based of grain size and organic carbon parameters. In these experiments, between 80 and 95% of particles were found to associate with the sediment, demonstrative of estuaries being a major anticipated sink for these contaminants. These materials show considerable promise in their versatility, potential for multiplexing, and utility in studying micro- and nano-plastic transport in real-world environments., Competing Interests: ST was employed by Postnova Analytics Inc.

Background: Nutrition therapy is essential in critically ill adults. Little is known about appropriate nutrition therapy in patients with severe coronavirus disease 2019 (COVID-19) infection., Methods: This was a retrospective, observational study in adult patients with confirmed COVID-19 infection receiving mechanical ventilation. Data regarding patient demographics and nutrition therapy were collected. Patients that received enteral nutrition within 24 hours of starting mechanical ventilation were compared with patients starting enteral nutrition later. The primary outcome was inpatient length of stay. Propensity score matching was conducted to control for baseline differences in patient groups., Results: One hundred fifty-five patients were included in final analysis. Patients who received enteral nutrition within 24 hours received a significantly greater daily amount of calories (17.5 vs 15.2 kcal/kg, P = .015) and protein (1.04 vs 0.85 g/kg, P = .003). There was no difference in length of stay (18.5 vs 23.5 days, P = .37). The propensity score analysis included 100 patients. Following propensity scoring, significant differences in daily calorie (17.7 [4.6] vs 15.1 [5.1] kcal/kg/d, P = .009) and protein (1.03 [0.35] vs 0.86 [0.38] g/kg/d, P = .014) provision remained. No differences in length of stay or other outcomes were noted in the propensity score analysis., Conclusion: Initiation of enteral nutrition within 24 hours was not associated with improved outcomes in mechanically ventilated adults with COVID-19. No harm was detected either. Future research should seek to clarify optimal timing of enteral nutrition initiation in patients with COVID-19 who require mechanical ventilation., (© 2021 American Society for Parenteral and Enteral Nutrition.)

Parenteral nutrition (PN) is a complex therapy with numerous opportunities for error during the prescribing, preparation, and administration processes. Advances in technology, such as computerized provider order entry (CPOE), electronic health records (EHRs), and clinical decision support (CDS) have helped decrease the risks associated with PN therapy. These technologies can be utilized to guide prescribing, provide automated safety checks, and increase overall safety and accuracy in PN ordering, compounding, and administration. In recent years, increased awareness of the risks associated with PN therapy, in particular issues with ordering and transcription, have magnified the need for improved support of PN ordering within currently available systems. Additionally, drug shortages continue to impact key components of PN admixtures, further increasing the risks associated with this complex therapy. These concerns and risks present an opportunity for the development of new functionality, as well as improvements in and innovative utilization of available technology within systems supporting the PN use process. This discussion will highlight the risks associated with PN, examine the role of drug shortages on the safety of this therapy, describe the application of available technology to manage shortages, and report the experience of using commercially available CDS tools at one academic medical center. It will also include a discussion of the transition from paper orders to CPOE/EHR-based orders for PN and the transition from one commercially available electronic system to another at this particular institution., (© 2020 American Society for Parenteral and Enteral Nutrition.)

Introduction: Errors have been reported in the literature to occur at each step of the parenteral nutrition (PN) use process, necessitating standardized processes, clinician competence, and open communication for those involved. This study was performed at Central Admixture Pharmacy Services (CAPS®) in collaboration with the American Society for Parenteral and Enteral Nutrition (ASPEN) with the purpose to study the need for and success of PN pharmacist interventions., Methods: A survey was developed and sent to all CAPS customers for study enrollment and to identify their demographic and practice characteristics. For those enrolled, CAPS pharmacists reviewed every PN order in a 1-month period using an error/intervention tool to capture data on prescription elements requiring intervention, along with acceptance of that intervention., Results: Two hundred thirty-two unique CAPS customers (23% response rate) participated in the study, representing 37,634 unique PN prescriptions. Two hundred forty-eight PN prescriptions (0.66%) from 59 customers required ≥1 intervention. The top 3 intervention types were electrolyte dose clarification, calcium/phosphorus incompatibility, and amino acid dose clarification. A greater number and percentage of interventions were required for neonatal prescriptions, as compared with adult and pediatric prescriptions. No significant difference was found in many of the other customer characteristics., Conclusion: This study supports the need for institutions to develop systems to comply with published PN safety recommendations, including knowledgeable and skilled pharmacists to complete the order review and verification steps for this high-alert medication., (© 2020 American Society for Parenteral and Enteral Nutrition.)

Intravenous in-line filters play a critical role in promoting patient safety during parenteral nutrition (PN) administration. Guidelines for using filters for PN have been issued by a number of professional organizations and manufacturers of PN components. Yet despite this guidance, filter use remains controversial. Recent changes in recommendations for filtering lipid injectable emulsions have added to confusion and created considerable variation in practice. This Position Paper aims to review past guidance regarding the filtration of PN, examine the clinical consequences of infusing particulate matter, discuss the challenges and issues related to filtration, and clarify the American Society for Parenteral and Enteral Nutrition (ASPEN) recommendations for the use of filters for PN administration. This paper was approved by the ASPEN Board of Directors., (© 2020 American Society for Parenteral and Enteral Nutrition.)

The 2013-2016 epidemic of Ebola virus disease (EVD) that originated in West Africa underscored many of the challenges to conducting clinical research during an ongoing infectious disease epidemic, both in the most affected countries of Guinea, Liberia, and Sierra Leone, as well as in the United States and Europe, where a total of 27 patients with EVD received care in biocontainment units. The Special Pathogens Research Network (SPRN) was established in the United States in November 2016 to provide an organizational structure to leverage the expertise of the 10 Regional Ebola and Other Special Pathogen Treatment Centers (RESPTCs); it was intended to develop and support infrastructure to improve readiness to conduct clinical research in the United States. The network enables the rapid activation and coordination of clinical research in the event of an epidemic and facilitates opportunities for multicenter research when the RESPTCs are actively caring for patients requiring a biocontainment unit. Here we provide an overview of opportunities identified in the clinical research infrastructure during the West Africa EVD epidemic and the SPRN activities to meet the ongoing challenges in the context of Ebola virus and other special pathogens.

The use of investigational therapeutics in the care of patients with Ebola virus disease was documented in the literature following the 2013-2016 outbreak. In order to access these types of therapeutics, facilities must have processes in place to quickly and efficiently activate study protocols, obtain the medications, and administer them in a timely manner. Testing these procedures in advance of a real-world event is crucial to ensuring successful implementation and execution. Drills and exercises are routinely used as part of the emergency preparedness planning process, as they provide a low-risk environment in which to test plans and procedures. Including research activities in full-scale emergency preparedness exercises is a novel approach that should be considered when creating a comprehensive special pathogen program. One important aspect of creating an agile response program is developing and sustaining strong relationships with key collaborators. Including departments not previously engaged in infectious disease preparedness exercises provides a forum to strengthen these relationships, clarify roles, and identify gaps. This article describes the process used to incorporate research-centric objectives focused on the use of investigational therapeutics for Ebola virus disease into a full-scale exercise, the evaluation process used to measure the identified objectives, and the results of the exercise.

The National Ebola Training and Education Center (NETEC) was established in 2015 in response to the 2014-2016 Ebola virus disease outbreak in West Africa. The US Department of Health and Human Services office of the Assistant Secretary for Preparedness and Response and the US Centers for Disease Control and Prevention sought to increase the competency of healthcare and public health workers, as well as the capability of healthcare facilities in the United States, to deliver safe, efficient, and effective care to patients infected with Ebola and other special pathogens nationwide. NYC Health + Hospitals/Bellevue, Emory University, and the University of Nebraska Medical Center/Nebraska Medicine were awarded this cooperative agreement, based in part on their experience in safely and successfully evaluating and treating patients with Ebola virus disease in the United States. In 2016, NETEC received a supplemental award to expand on 3 initial primary tasks: (1) develop metrics and conduct peer review assessments; (2) develop and provide educational materials, resources, and tools, including exercise design templates; (3) provide expert training and technical assistance; and, to add a fourth task, create a special pathogens clinical research network.

Background: Shortages of parenteral nutrition (PN) components have been common in recent years. Effects on patient management and outcomes have not been well documented. This study aimed to determine the effect of a parenteral magnesium shortage, and an institutional decision to omit magnesium from adult PN, on magnesium and potassium doses and serum concentrations., Materials and Methods: This was a retrospective cohort study of adult surgical patients during two 6-month periods: prior to the magnesium shortage (2011) and during the shortage (2012). The relation between study period and electrolyte doses was evaluated by unadjusted and adjusted mixed models, while the relation between study period and hypokalemia and hypomagnesemia exposure was evaluated by Student's t tests and multiple linear regression., Results: During the shortage, patients received more supplemental magnesium (0.11-0.12 mEq/kg/d, P < .0001) but received less total daily magnesium (0.08-0.09 mEq/kg/d, P < .0001) and had greater exposure to hypomagnesemia (9.6-14.2 h·mcg/dL/h, P < .05 for all comparisons except multivariate analysis in a matched subpopulation). Patients received similar amounts of potassium in PN (0.06-0.08 mEq/kg/d less, P < .05 for full cohort but P > .05 for matched cohort), in supplemental doses (0.01-0.05 mEq/kg/d less, P > .05), and in total (0.07-0.14 mEq/kg/d less, P > .05), and they had similar exposure to hypokalemia., Conclusion: Daily magnesium doses were lower and hypomagnesemia exposure was greater during the shortage, but the differences were numerically small and their clinical significance was questionable. Potassium doses and hypokalemia exposure were not higher during the shortage. This supports the strategy of omitting magnesium from PN of select patients and supplementing as clinically necessary., (© 2015 American Society for Parenteral and Enteral Nutrition.)

Purpose: To assist the pharmacy clinician engaged in nutrition support in staying current with the most pertinent literature., Methods: Several experienced board-certified clinical pharmacists engaged in nutrition support therapy compiled a list of articles published in 2014 and 2015 that they considered to be important to their practice. Only those articles available in print format were considered for potential inclusion. Articles available only in preprint electronic format were not evaluated. The citation list was compiled into a single spreadsheet where the author participants were asked to ascertain whether they considered the paper important to nutrition support pharmacy practice. A culled list of publications was then identified whereby the majority of author participants (at least 5 out of 8) considered the paper to be important., Results: A total of 108 articles were identified; 36 of which were considered to be of high importance. An important guideline article published in early 2016, but not ranked, was also included. The top-ranked articles from the primary literature were reviewed., Conclusion: It is recommended that the informed pharmacist, who is engaged in nutrition support therapy, be familiar with the majority of these articles.

Objective: Comorbidities such as cardiovascular diseases (CVD), cancer, osteoporosis, and depression are often underrecognized in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), or psoriasis (PsO). Recommendations may improve identification and treatment of comorbidities. The Canadian Dermatology-Rheumatology Comorbidity Initiative reviewed the literature to develop practical evidence-based recommendations for management of comorbidities in patients with RA, PsA, and PsO., Methods: Eight main topics regarding comorbidities in RA, PsA, and PsO were developed. MEDLINE, EMBASE, and the Cochrane Library (1960-12/2012), together with abstracts from major rheumatology and dermatology congresses (2010-2012), were searched for relevant publications. Selected articles were analyzed and metaanalyses performed whenever possible. A meeting including rheumatologists, dermatologists, trainees/fellows, and invited experts was held to develop consensus-based recommendations using a Delphi process with prespecified cutoff agreement. Level of agreement was measured using a 10-point Likert scale (1 = no agreement, 10 = full agreement) and the potential effect of recommendations on daily clinical practice was considered. Grade of recommendation (ranging from A to D) was determined according to the Oxford Centre for Evidence-Based Medicine evidence levels., Results: A total of 17,575 articles were identified, of which 407 were reviewed. Recommendations were synthesized into 19 final recommendations ranging mainly from grade C to D, and relating to a large spectrum of comorbidities observed in clinical practice: CVD, obesity, osteoporosis, depression, infections, and cancer. Level of agreement ranged from 80.9% to 95.8%., Conclusion: These practical evidence-based recommendations can guide management of comorbidities in patients with RA, PsA, and PsO and optimize outcomes.

Phosphorus (P) and calcium (Ca) serve vital roles in the human body and are essential components of nutrition support therapy. Regulation of P and regulation of Ca in the body are closely interrelated, and P and Ca homeostasis can be affected by several factors, including disease states, clinical condition, severity of illness, and medications. Nutrition support clinicians must understand these factors to prevent and treat P and Ca disorders in patients receiving nutrition support therapy. This review provides an overview of P and Ca for the adult nutrition support clinician, with some emphasis on the hospitalized inpatient., (© 2014 American Society for Parenteral and Enteral Nutrition.)

Purpose: To assist the pharmacy clinician engaged in nutrition support in staying current with the most pertinent literature., Methods: Several experienced board-certified clinical pharmacists in nutrition support compiled a list of publications published in 2013 that they considered to be important to their practice. The citation list was compiled into a Web-based survey whereby pharmacist members of the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.), GI-Liver-Nutrition Practice Research Network of the American College of Clinical Pharmacy, and the Pharmacy and Pharmacology Section of the Society of Critical Care Medicine were asked to rank each article according to level of importance in their practice., Results: A total of 30 articles were identified by the author group. Thirty-six participants responded to the survey. The top-ranked papers by participants from the Web-based survey were reviewed by the authors. Due to its high level of importance, the parenteral nutrition safety consensus recommendations article, to be published in 2014 by A.S.P.E.N., was also reviewed., Conclusion: It is recommended that the informed pharmacist, who is engaged in nutrition support therapy, be familiar with the majority of these publications.

Objective: Venous thromboembolism (VTE) is the leading cause of preventable death in hospitalized patients. Educational videos have been effectively used to increase patient satisfaction and knowledge. This study examined possible benefits of an educational video about VTE., Methods: Medical patients receiving VTE prophylaxis were screened within 48 h of admission. Upon enrollment, patients were randomly assigned to either watch a 5 min educational video on VTE or not, in addition to standard VTE education. Within 24-48 h after randomization, all patients completed a survey assessing VTE prophylaxis knowledge and satisfaction., Results: Patients who watched the video averaged 83% correct responses to knowledge-based questions (regarding VTE risk, symptoms, and preventative measures) versus an average score of 62% for patients in the no video group (p<0.001). Patients who watched the video were more satisfied with their VTE education (4.8 vs. 3.4 out of 5, p<0.001)., Conclusion: This educational video effectively provided baseline information to patients about VTE and improved patient satisfaction., Practice Implications: A VTE educational video can be an effective tool for improving patient knowledge of the condition., (Copyright © 2014 Elsevier Ireland Ltd.

Background: Alkalinized Viokase pancreatic enzyme tablets restored patency to 71.9% of occluded Dobhoff tubes in a prospective study. After removal of Viokase tablets from the US market, the hospital protocol for unclogging enteral feeding tubes was adapted to use Creon pancreatic enzyme delayed-release capsules, despite the lack of published data., Objective: To evaluate the effectiveness of a Creon-based protocol to clear occluded enteral feeding tubes., Methods: This retrospective study included all adult and pediatric patients seen in the emergency department or in an inpatient setting who received Creon 12 000 units lipase delayed-release capsule dissolved in a solution of sodium bicarbonate 650 mg and sterile water for clearing occluded enteral feeding tubes between May 1 and November 30, 2010. The Creon protocol was deemed effective if tube clearance was documented in the medical record or if enteral feedings were resumed with no note regarding tube replacement., Results: Alkalinized Creon delayed-release capsules were administered to 83 patients with a total of 118 clogged tubes. Three poorly documented cases and 5 tubes with mechanical clogs were excluded from data analysis. Patency was restored to 53 of 110 (48.2%) occluded tubes. More than 1 treatment course was attempted in 5 cases, with success in 3., Conclusion: An alkalinized Creon pancreatic enzyme protocol was effective in clearing approximately half of the occluded enteral feeding tubes in this retrospective study, an efficacy rate much less than that previously reported in the literature with a Viokase-based protocol.

Parenteral nutrition (PN) serves as an important therapeutic modality that is used in adults, children, and infants for a variety of indications. The appropriate use of this complex therapy aims to maximize clinical benefit while minimizing the potential risks for adverse events. Complications can occur as a result of the therapy and as the result of the PN process. These consensus recommendations are based on practices that are generally accepted to minimize errors with PN therapy, categorized in the areas of PN prescribing, order review and verification, compounding, and administration. These recommendations should be used in conjunction with other A.S.P.E.N. publications, and researchers should consider studying the questions brought forth in this document.

Background: Vasopressors used for the management of septic shock are often dosed according to body weight. Use of vasopressin for physiologic replacement in patients with septic shock is usually administered as a standard non-weight-based dose. We hypothesized that the efficacy of vasopressin may be influenced by body weight., Purpose: The primary objective was to determine if the effects of vasopressin on other vasopressor dosing requirements is related to body weight. Secondary objectives included evaluation of blood pressure and heart rate after the start of vasopressin infusion., Methods: A retrospective, cohort study in a large academic health center was conducted. Sixty-four adult inpatients with septic shock (26 medical intensive care unit and 38 surgical intensive care unit) who required vasopressor administration including vasopressin therapy were included. Dosing requirements of vasopressors were captured 1 hour before and during the hour of vasopressin initiation and 2 and 4 hours later. Other information collected during the study period included blood pressure, mean arterial pressure, and heart rate., Results: Most of the patients (n = 61) received vasopressin at a dose of 0.04 U/min. Changes in vasopressor dosing were significantly correlated with weight-adjusted vasopressin at 2 hours (correlation coefficient = -0.36, P = .03) and 4 hours (correlation coefficient = -0.46, P < .001). Use of vasopressin was associated with significant increases in systolic blood pressure, diastolic blood pressure, and mean arterial pressure at each time point compared with baseline., Conclusions: Effects of vasopressin on catecholamine dosing requirements in the setting of septic shock may be influenced by body weight. Prospective studies are needed to examine weight-based dosing of vasopressin in this setting., (Copyright © 2012 Elsevier Inc. All rights reserved.)
