International Care programs for Pediatric Post-COVID Condition (Long COVID) and the way forward.

BACKGROUND: Pediatric Post-COVID-Condition (PPCC) clinics treat children despite limited scientific substantiation. By exploring real-life management of children diagnosed with PPCC, the International Post-COVID-Condition in Children Collaboration (IP4C) aimed to provide guidance for future PPCC care. METHODS: We performed a cross-sectional international, multicenter study on used PPCC definitions; the organization of PPCC care programs and patients characteristics. We compared aggregated data from PPCC cohorts and identified priorities to improve PPCC care. RESULTS: Ten PPCC care programs and six COVID-19 follow-up research cohorts participated. Aggregated data from 584 PPCC patients was analyzed. The most common symptoms included fatigue (71%), headache (55%), concentration difficulties (53%), and brain fog (48%). Severe limitations in daily life were reported in 31% of patients. Most PPCC care programs organized in-person visits with multidisciplinary teams. Diagnostic testing for respiratory and cardiac morbidity was most frequently performed and seldom abnormal. Treatment was often limited to physical therapy and psychological support. CONCLUSIONS: We found substantial heterogeneity in both the diagnostics and management of PPCC, possibly explained by scarce scientific evidence and lack of standardized care. We present a list of components which future guidelines should address, and outline priorities concerning PPCC care pathways, research and international collaboration. IMPACT: Pediatric Post-COVID Condition (PPCC) Care programs have been initiated in many countries. Children with PPCC in different countries are affected by similar symptoms, limiting many to participate in daily life. There is substantial heterogeneity in diagnostic testing. Access to specific diagnostic tests is required to identify some long-term COVID-19 sequelae. Treatments provided were limited to physical therapy and psychological support. This study emphasizes the need for evidence-based diagnostics and treatment of PPCC. The International Post-COVID Collaboration for Children (IP4C) provides guidance for guideline development and introduces a framework of priorities for PPCC care and research, to improve PPCC outcomes.

Caring for two in the ICU: Pharmacologic management of pregnancy-related complications.

Maternal mortality continues to be an issue globally despite advances in technology and pharmacotherapy. Pregnancy can lead to complications that necessitate immediate action to prevent severe morbidity and mortality. Patients may need escalation to the ICU setting for close monitoring and administration of advanced therapies not available elsewhere. Obstetric emergencies are rare but high-stakes events that require clinicians to have prompt identification and management. The purpose of this review is to describe complications of pregnancy and provide a focused resource of pharmacotherapy considerations that clinicians may encounter. For each disease state, the epidemiology, pathophysiology, and management are summarized. Brief descriptions of non-pharmacological (e.g., cesarean or vaginal delivery of the baby) interventions are provided. Mainstays of pharmacotherapy highlighted include oxytocin for obstetric hemorrhage, methotrexate for ectopic pregnancy, magnesium and antihypertensive agents for preeclampsia and eclampsia, eculizumab for atypical hemolytic uremic syndrome, corticosteroids, and immunosuppressive agents for thrombotic thrombocytopenic purpura, diuretics, metoprolol, and anticoagulation for peripartum cardiomyopathy, and pulmonary vasodilators for amniotic fluid embolism.

Caring for two in the ICU: Pharmacotherapy in the critically ill pregnant patient.

Safe and thoughtful medication management of pregnant patients requiring intensive care unit (ICU) level of care is key to optimizing outcomes for both mother and fetus. Pregnancy induces physiologic alterations that closely mirror the changes expected in a critically ill patient. These changes can be predictable depending on the gestational age and trimester and will directly impact the pharmacokinetic profile of medications commonly used in the ICU; examples include decreased gastric emptying, increased blood and plasma volume, increased glomerular filtration, and increased cardiac output. When pregnant patients require ICU care, the resulting impact on drug absorption, distribution, metabolism, and elimination can be difficult to predict. In addition, there are many nuances of medication metabolism and interface with the placental barrier that should be considered when selecting pharmacotherapy for the pregnant patient. Critical care clinicians need to be aware of medication interactions with the placenta and weigh the risk versus benefit profile of medication use in this patient population. Obstetric critical care admissions have increased over the years, especially during the coronavirus waves. Therefore, understanding the interplay between pregnancy and critical illness to optimize pharmacotherapy selection is crucial to improving health outcomes of mother and fetus. This review highlights pharmacotherapy considerations in the pregnant ICU patient for the following topics: physiologic alterations, categorizing medication risk, supportive care, sepsis, cardiogenic shock, acute respiratory distress syndrome, and venous thromboembolism.

Corticosteroid use in ARDS and its application to evolving therapeutics for coronavirus disease 2019 (COVID-19): A systematic review.

Data regarding the use of corticosteroids for treatment of acute respiratory distress syndrome (ARDS) are conflicting. As the coronavirus disease 2019 (COVID-19) pandemic progresses, more literature supporting the use of corticosteroids for COVID-19 and non-COVID-19 ARDS have emerged. Glucocorticoids are proposed to attenuate the inflammatory response and prevent progression to the fibroproliferative phase of ARDS through their multiple mechanisms and anti-inflammatory properties. The purpose of this systematic review was to comprehensively evaluate the literature surrounding corticosteroid use in ARDS (non-COVID-19 and COVID-19) in addition to a narrative review of clinical considerations of corticosteroid use in these patient populations. OVID Medline and EMBASE were searched. Randomized controlled trials evaluating the use of corticosteroids for COVID-19 and non-COVID-19 ARDS in adult patients on mortality outcomes were included. Risk of bias was assessed with the Risk of Bias 2.0 tool. There were 388 studies identified, 15 of which met the inclusion criteria that included a total of 8877 patients. The studies included in our review reported a mortality benefit in 6/15 (40%) studies with benefit being seen at varying time points of mortality follow-up (ICU survival, hospital, and 28 and 60 days) in the COVID-19 and non-COVID-19 ARDS studies. The two non-COVID19 trials assessing lung injury score improvements found that corticosteroids led to significant improvements with corticosteroid use. The number of mechanical ventilation-free days significantly were found to be increased with the use of corticosteroids in all four studies that assessed this outcome. Corticosteroids are associated with improvements in mortality and ventilator-free days in critically ill patients with both COVID-19 and non-COVID-19 ARDS, and evidence suggests their use should be encouraged in these settings. However, due to substantial differences in the corticosteroid regimens utilized in these trials, questions still remain regarding the optimal corticosteroid agent, dose, and duration in patients with ARDS.

Some characteristics of hyperglycaemic crisis differ between patients with and without COVID-19 at a safety-net hospital in a cross-sectional study.

OBJECTIVE: To compare patients with DKA, hyperglycaemic hyperosmolar syndrome (HHS), or mixed DKA-HHS and COVID-19 [COVID (+)] to COVID-19-negative (-) [COVID (-)] patients with DKA/HHS from a low-income, racially/ethnically diverse catchment area. METHODS: A cross-sectional study was conducted with patients admitted to an urban academic medical center between 1 March and 30 July 2020. Eligible patients met lab criteria for either DKA or HHS. Mixed DKA-HHS was defined as meeting all criteria for either DKA or HHS with at least 1 criterion for the other diagnosis. RESULTS: A total of 82 participants were stratified by COVID-19 status and type of hyperglycaemic crisis [26 COVID (+) and 56 COVID (-)]. A majority were either Black or Hispanic. Compared with COVID (-) patients, COVID (+) patients were older, more Hispanic and more likely to have type 2 diabetes (T2D, 73% vs 48%, p < .01). COVID(+) patients had a higher mean pH (7.25 ± 0.10 vs 7.16 ± 0.16, p < .01) and lower anion gap (18.7 ± 5.7 vs 22.7 ± 6.9, p = .01) than COVID (-) patients. COVID (+) patients were given less intravenous fluids in the first 24 h (2.8 ± 1.9 vs 4.2 ± 2.4 L, p = .01) and were more likely to receive glucocorticoids (95% vs. 11%, p < .01). COVID (+) patients may have taken longer to resolve their hyperglycaemic crisis (53.3 ± 64.8 vs 28.8 ± 27.5 h, p = .09) and may have experienced more hypoglycaemia <3.9 mmol/L (35% vs 19%, p = .09). COVID (+) patients had a higher length of hospital stay (LOS, 14.8 ± 14.9 vs 6.5 ± 6.0 days, p = .01) and in-hospital mortality (27% vs 7%, p = .02). DISCUSSION: Compared with COVID (-) patients, COVID (+) patients with DKA/HHS are more likely to have T2D. Despite less severe metabolic acidosis, COVID (+) patients may require more time to resolve the hyperglycaemic crisis and experience more hypoglycaemia while suffering greater LOS and risk of mortality. Larger studies are needed to examine whether differences in management between COVID (+) and (-) patients affect outcomes with DKA/HHS.

Providing pharmacy services in a basketball arena: Reflections on building a pharmacy in a COVID-19 surge facility.

PURPOSE: As Coronavirus disease 19 (COVID-19) has spread globally, hospital systems have seen an increasing strain on their ability to accommodate the growing caseload. This demand has led countries to adopt varying surge-facility or alternate care site (ACS) models to manage patient overflow. This report describes the experience of setting up pharmacy services at a city-run surge facility in Philadelphia. SUMMARY: The COVID-19 Surge Facility at the Liacouras Center (CSF-L) was initially developed to serve as a site for patients convalescing from acute inpatient stays in order to free up healthcare resources in surrounding hospitals. The CSF-L site required a distinct set of services to provide the desired level of care. This report details the preparations and challenges faced by the CSF-L pharmacy team in this endeavor, including identifying a pharmacy location that met regulatory requirements, obtaining proper licenses, coordinating drug procurement, filling staffing requirements, developing a formulary, defining the pharmacy and medication management workflow, and ensuring safety protocols were followed. This report explains the rational for developing certain processes and suggests alternative options and ideal plans for developing future pharmacy services in an ACS. CONCLUSION: Identifying a pharmacy leadership team early in the ACS planning process can lead to more efficient plans for pharmacy services. This report details the important steps taken, decisions made, and challenges faced in setting up pharmaceutical services at a COVID-19 field hospital.

Pharmacokinetics of linezolid for methicillin-resistant Staphylococcus aureus pneumonia in an adult receiving extracorporeal membrane oxygenation.

PURPOSE: We present a case of a 55-year-old man post right lung transplantation receiving ECMO for treatment of respiratory failure secondary to methicillin-resistant Staphylococcus aureus (MRSA) pneumonia. SUMMARY: Extracorporeal membrane oxygenation (ECMO) is a frequently utilized support therapy for patients with cardiac and/or respiratory failure. Dosing of medications during ECMO can be challenging due to several factors, including sequestration of medications within ECMO circuits, alterations in volume of distribution, and changes in drug clearance. The patient was initiated on empiric antibiotics, then switched to linezolid at a dose of 600 mg every 8 hours. Linezolid plasma concentrations were collected 30 minutes prior to the sixth administered dose and 30 minutes following the 1-hour infusion of the sixth dose, which resulted in values of 0.4 and 1.7 µg/mL, respectively. The ratio of 24-hour area under the curve (AUC0-24) to minimum inhibitory concentration (MIC), assuming a MIC of 2 µg/mL, was calculated using the extrapolated maximum concentration (1.9 µg/mL) and minimum concentration (0.35 µg/mL), resulting in an AUC0-24/MIC value of 10.8. Due to subtherapeutic linezolid plasma concentrations, ceftaroline was initiated and continued for a total of 18 days. To our knowledge, this is the second report to describe inadequate plasma concentrations of linezolid during ECMO. CONCLUSION: In the case described here, linezolid at a dose of 600 mg every 8 hours did not achieve target plasma concentrations in a patient receiving concomitant venovenous ECMO support.

Student Characteristics Associated with Successful Matching to a PGY1 Residency Program.

Objective. To identify predictors for postgraduate matching success. Methods. In April 2014, a survey was distributed to students at five schools of pharmacy in the United States assessing organizational involvement, research and work experience, postgraduation plans, match status, and demographics. Results. Five hundred seventy-seven students (82%) completed the survey. Applicants who matched had a higher median number of interview offers compared to those who did not match. Significantly more females than males applied for a residency program. Those who matched had a higher median pharmacy school grade point average (GPA) compared to those who did not. No differences were observed in the rates of matching when leadership positions, student organizational membership, or previous work experience were considered. Conclusion. For pharmacy students in this study, number of applications and interviews, pharmacy school GPA, and female gender were associated with a higher likelihood of matching.

Comparison of the efficacy and safety of two different insulin infusion protocols in the medical intensive care unit.

BACKGROUND: New guidelines recommend using less intensive glycemic goals in critically ill patients receiving insulin infusions. OBJECTIVE: To compare the efficacy and safety of a modified insulin infusion protocol (MIIP) with less stringent blood glucose (BG) goals to an intensive insulin infusion protocol (IIIP) in patients in a medical intensive care unit (MICU). METHODS: Retrospective review of patients receiving an insulin infusion for at least 24 hours. Patients treated for hyperglycemic emergencies were excluded. The primary endpoint of the study was mean area under the BG curve (BG-AUC) at 24 and 48 hours. Other endpoints included mean BG, hours until BG at goal, rate of BG above goal, frequency of BG measurements, and rate of hypoglycemia. RESULTS: BG-AUC at 24 hours was similar between the groups (MIIP = 5177.7 ± 1221.3 mg/dL x h vs IIIP = 4850.3 ± 1301.7 mg/dL x h; P = .20). The mean BG level at 24 hours was 225.1 ± 91.1 mg/dL in the MIIP group and 205.7 ± 89.7 mg/dL in the IIIP group (P = .06). In the MIIP group, 61.7% of the BG levels were above goal as compared to 87.5% in the IIIP group (P < .0001). Patients were able to achieve BG goals faster with the MIIP (12.58 ± 10.5 hours vs 29.37 ± 16.8 hours; P < .001). The rate of severe hypoglycemia was lower at 24 hours in the patients following the MIIP (0% vs 0.3%; P = .01). CONCLUSION: The study showed that by having less intensive glycemic goals, goal BG levels can achieved faster and the rate of severe hypoglycemia can decrease.

Loss of phosphoinositide 3-kinase gamma decreases migration and activation of phagocytes but not T cell activation in antigen-induced arthritis.

BACKGROUND: Phosphoinositide 3-kinase gamma (PI3Kgamma) has been depicted as a major regulator of inflammatory processes, including leukocyte activation and migration towards several chemokines. This study aims to explore the role of PI3Kgamma in the murine model of antigen-induced arthritis (AIA). METHODS: Development of AIA was investigated in wildtype and PI3Kgamma-deficient mice as well as in mice treated with a specific inhibitor of PI3Kgamma (AS-605240) in comparison to untreated animals. Inflammatory reactions of leukocytes, including macrophage and T cell activation, and macrophage migration, were studied in vivo and in vitro. RESULTS: Genetic deletion or pharmacological inhibition of PI3Kgamma induced a marked decrease of clinical symptoms in early AIA, together with a considerably diminished macrophage migration and activation (lower production of NO, IL-1beta, IL-6). Also, macrophage and neutrophil infiltration into the knee joint were impaired in vivo. However, T cell functions, measured by cytokine production (TNFalpha, IFNgamma, IL-2, IL-4, IL-5, IL-17) in vitro and DTH reaction in vivo were not altered, and accordingly, disease developed normally at later timepoints CONCLUSION: PI3Kgamma specifically affects phagocyte function in the AIA model but has no impact on T cell activation.

Severe pseudomembranous colitis after moxifloxacin use: a case series.

OBJECTIVE: To describe the illnesses of 4 patients who developed severe pseudomembranous colitis after receiving moxifloxacin. CASE SUMMARY: Four patients received moxifloxacin for pulmonary infections prior to developing positive Clostridium difficile toxin assays; all 4 later died from complications associated with C. difficile-associated disease (CDAD). Three patients developed CDAD while outpatients, although all of them had recent hospitalizations and their disease was presumed to be hospital related. All patients presented with diffuse abdominal pain, fever, and diarrhea. The patients were all treated surgically with total abdominal colectomies and medically with metronidazole. DISCUSSION: Recent reports have highlighted the connection between fluoroquinolones and CDAD, in contrast to historical studies and assumptions. Evidence in the literature about differences in the propensity of various fluoroquinolones to cause CDAD is conflicting. The Naranjo probability scale revealed a probable relationship between moxifloxacin and CDAD for 3 patients, and a possible relationship for 1 patient. CONCLUSIONS: Our cases highlight the need for vigilance in monitoring patients for signs of CDAD when using any antibiotic, including moxifloxacin. Patients with suspected severe CDAD need to be managed aggressively to avoid poor outcomes.

Prophylactic antibiotic use: hardwiring of physician behavior, not education, leads to compliance.

BACKGROUND: Surgical wound infections can be significantly reduced by appropriate administration of prophylactic antibiotics (ProAbx). The purpose of this study was to determine the effect of interventions, specifically, forced functions, designed to improve administration of ProAbx in a university hospital setting. STUDY DESIGN: We retrospectively reviewed charts from 1,622 consecutive patients, seen between March 2005 and June 2007, for evaluation of ProAbx administration to determine correct choice, appropriate timing of administration, and appropriate postoperative cessation of antibiotics. Processes designed to improve compliance were devising orders to limit ProAbx choice; requiring those orders in preadmission testing; administering ProAbx in the preparation and hold area, subsequently, at the time of the universal timeout; and standardizing postoperative orders in the computerized physician order entry. RESULTS: Specialty-specific standardized orders improved compliance from 76% to 91% (p < 0.001) concerning ProAbx choice. Regarding timing of preoperative administration, a baseline compliance of 55% improved to: 78% (p < 0.001) on requiring orders in the preadmission testing area; 90% (p < 0.008) on administering ProAbx in the preparation and hold area; and 95% (p < 0.07) when ProAbx were administered at the universal timeout. Standardization of postoperative orders in the computerized physician order entry improved compliance with cessation from 60% to 86%, p < 0.001. CONCLUSIONS: Despite hospital-wide education, improving compliance with evidence-based recommendations for ProAbx required processes that "forced" physician behavior, specifically: specialty-specific, preprinted physician orders limiting ProAbx choice; linking administration of preoperative ProAbx administration to the universal timeout; and standardization of the postoperative ProAbx order in the computerized physician order entry.

Fibroblast-like synovial cells from normal and inflamed knee joints differently affect the expression of pain-related receptors in sensory neurones: a co-culture study.

Innervation of the joint with thinly myelinated and unmyelinated sensory nerve fibres is crucial for the occurrence of joint pain. During inflammation in the joint, sensory fibres show changes in the expression of receptors that are important for the activation and sensitization of the neurones and the generation of joint pain. We recently reported that both neurokinin 1 receptors and bradykinin 2 receptors are upregulated in dorsal root ganglion (DRG) neurones (the cell bodies of sensory fibres) in the course of acute and chronic antigen-induced arthritis in the rat. In this study, we begin to address mechanisms of the interaction between fibroblast-like synovial (FLS) cells and sensory neurones by establishing a co-culture system of FLS cells and DRG neurones. The proportion of DRG neurones expressing neurokinin 1 receptor-like immunoreactivity was not altered in the co-culture with FLS cells from normal joints but was significantly upregulated using FLS cells from knee joints of rats with antigen-induced arthritis. The proportion of DRG neurones expressing bradykinin 2 receptors was slightly upregulated in the presence of FLS cells from normal joints but upregulation was more pronounced in DRG neurones co-cultured with FLS cells from acutely inflamed joints. In addition, the expression of the transient receptor potential V1 (TRPV1) receptor, which is involved in inflammation-evoked thermal hyperalgesia, was mainly upregulated by co-culturing DRG neurones with FLS cells from chronically inflamed joints. Upregulation of neurokinin 1 receptors but not of bradykinin 2 and TRPV1 receptors was also observed when only the supernatant of FLS cells from acutely inflamed joint was added to DRG neurones. Addition of indomethacin to co-cultures inhibited the effect of FLS cells from acutely inflamed joints on neurokinin 1 receptor expression, suggesting an important role for prostaglandins. Collectively, these data show that FLS cells are able to induce an upregulation of pain-related receptors in sensory neurones and, thus, they could contribute to the generation of joint pain. Importantly, the influence of FLS cells on DRG neurones is dependent on their state of activity, and soluble factors as well as direct cellular contacts are crucial for their interaction with neurones.

Emergence of resistance of vancomycin-resistant Enterococcus faecium in a thermal injury patient treated with quinupristin-dalfopristin and cultured epithelial autografts for wound closure.

Vancomycin-resistant Enterococcus faecium and faecalis (VRE) remains a major complication among critically ill patients. A 26-year-old patient with 65% total body surface area burns (TBSA) was infected with several E. faecium strains during his admission that were resistant to vancomycin. Because chloramphenicol was the standard treatment at this time, this drug was initiated until, the organism was identified as E. faecium and reported as susceptible to quinupristin-dalfopristin. Given these data, it was then decided to discontinue the chloramphenicol therapy. Quinupristin-dalfopristin therapy resulted in initial reduction of fever and white blood cell counts that continued over the next 5 days. However, on day 7 of quinupristin-dalfopristin therapy, a return of fever and elevation of the white blood cell count was noted and a repeated E. faecium blood culture demonstrated sudden resistance to quinupristin-dalfopristin (Bauer-Kirby zone size <14 mm). Chloramphenicol was restarted and the patient improved slowly over a period of 16 days. Our indigenous VRE had limited exposure to quinupristin-dalfopristin in the recent past; however, resistance emerged with the first commercial use of this agent in our burn treatment center. High-dose chloramphenicol treatment did not appear to impair engraftment of cultured epithelial autografts (CEA) in this patient.
