Development of a workforce self-assessment tool for public health emergency preparedness.

BACKGROUND: In collaboration with six European public health agencies as part of the PANDEM-2 consortium, we have developed and validated a self-assessment tool that captures the workforce capacities and capabilities needed at the institutional level within National Public Health Institutes (NPHIs) to deal with public health emergencies. METHODS: The work carried out in this study included (i) a review of existing tools for workforce assessment, (ii) focus group discussions and interviews to map the experiences and needs of NPHI's, (iii) the development of a tool for NPHI's to assess their workforce capacity and capabilities in public health emergency preparedness (PHEP) and (iv) refinement of the assessment tool via a Delphi study. RESULTS: Capacity markers were identified to assess the workforce required for PHEP functions and the availability of surge capacity during a public health emergency. The tool also enables NPHIs to analyze gaps in PHEP staff competencies. The assessment scores can assist NPHI pandemic preparedness by identifying and prioritizing training and recruitment needs. CONCLUSIONS: In line with EU Regulation 2022/2371 on serious cross-border threats to health, article 11 Training of healthcare staff and public health staff, Member States (MS) are tasked with assessing current workforce capacity and capability gaps. The PANDEM-2 workforce self-assessment tool aligns with this requirement and will support effective planning and development to strengthen the public health workforce capacity in EU MS.

PANDEM-Source, a tool to collect or generate surveillance indicators for pandemic management: a use case with COVID-19 data.

Introduction: PANDEM-Source (PS) is a tool to collect and integrate openly available public health-related data from heterogeneous data sources to support the surveillance of infectious diseases for pandemic management. The tool may also be used for pandemic preparedness by generating surveillance data for training purposes. It was developed as part of the EU-funded Horizon 2020 PANDEM-2 project during the COVID-19 pandemic as a result of close collaboration in a consortium of 19 partners, including six European public health agencies, one hospital, and three first responder organizations. This manuscript describes PS's features and design to disseminate its characteristics and capabilities to strengthen pandemic preparedness and response. Methods: A requirement-gathering process with EU pandemic managers in the consortium was performed to identify and prioritize a list of variables and indicators useful for surveillance and pandemic management. Using the COVID-19 pandemic as a use case, we developed PS with the purpose of feeding all necessary data to be displayed in the PANDEM-2 dashboard. Results: PS routinely monitors, collects, and standardizes data from open or restricted heterogeneous data sources (users can upload their own data). It supports indicators and health resources related data from traditional data sources reported by national and international agencies, and indicators from non-traditional data sources such as those captured in social and mass media, participatory surveillance, and seroprevalence studies. The tool can also calculate indicators and be used to produce data for training purposes by generating synthetic data from a minimal set of indicators to simulate pandemic scenarios. PS is currently set up for COVID-19 surveillance at the European level but can be adapted to other diseases or threats and regions. Conclusion: With the lessons learnt during the COVID-19 pandemic, it is important to keep building capacity to monitor potential threats and develop tools that can facilitate training in all the necessary aspects to manage future pandemics. PS is open source and its design provides flexibility to collect heterogeneous data from open data sources or to upload end users's own data and customize surveillance indicators. PS is easily adaptable to future threats or different training scenarios. All these features make PS a unique and valuable tool for pandemic management.

Key Factors Impacting a Medical Ventilator Supply Chain During the COVID- 19 Pandemic: Lessons for Pandemic Preparedness.

OBJECTIVES: Future pandemics may cause more severe respiratory illness in younger age groups than COVID-19, requiring many more mechanical ventilators. This publication synthesizes the experiences of diverse contributors to Medtronic's mechanical ventilator supply chain during the pandemic, serving as a record of what worked and what didn't, while identifying key factors affecting production ramp-up in this healthcare crisis. METHOD: In-depth, one-on-one interviews (n = 17) were held with key Medtronic personnel and suppliers. Template analysis was used, and interview content was analyzed for signals, initiatives, actions, and outcomes, as well as influencing forces. RESULTS: Key findings revealed many factors limiting ventilator production ramp-up. Supply chain strengths and weaknesses were identified. Political factors played a role in allocating ventilators and also supported production. Commercial considerations were not priority, but economic awareness was essential to support suppliers. Workers were motivated and flexible. Component shortages, space, production processes, and logistics were challenges. Legally based pressures were reported e.g., import and export restrictions. CONCLUSION: Crisis response alone is not enough; preparation is essential. Coordinated international strategies are more effective than individual country responses. Supply chain resilience based on visibility and flexibility is key. This research can help public health planners and the medical device industry prepare for future healthcare crises.

Biosafety Issues in Patient Transport during COVID-19: A Case Study on the Portuguese Emergency Services.

During the COVID-19 pandemic, first responders faced significant biosafety challenges, especially while handling patient transport, potentially exposing them to infection. The PANDEM-2 (European project on pandemic preparedness and response) project, funded by the Horizon 2020 program, sought to investigate the challenges confronting Emergency Medical Systems throughout the EU. First responders from Portugal's National Institute of Medical Emergency (INEM) were considered as a representative operational model of the national first responder agencies of European member states because they played a critical role during the COVID-19 pandemic. As a result, they were asked to complete an online survey about their COVID-19 pandemic-related professional activities. The survey focused on their perspectives on current biosafety guidelines and their operational practices. It covered opinions on existing protocols, technical concerns during patient transport, and issues after the patients arrived at the hospital. The key findings revealed concerns about risk assessment, the inadequacy of guidelines, and disparities in equipment access. This survey emphasizes the importance of developing streamlined, adaptable biosafety protocols, better coordination between prehospital and in-hospital services, and the development of scalable, cost-effective biosafety solutions. Based on our findings, we propose improvements to national and European biosafety directives and advocate for streamlined adaptation during pandemics.

A rare cause of posterior reversible encephalopathy syndrome: Acute lymphoblastic leukemia.

Key Clinical Message: The presentation of posterior reversible encephalopathy syndrome (PRES) as the initial presenting sign of acute lymphoblastic leukemia is unusual, as PRES is more often a complication of therapy. This case highlights the importance of maintaining a broad differential diagnosis for pediatric hypertension and its complications. Abstract: A 6-year-old male presented with a seizure-like episode. Evaluation revealed hypertension and brain imaging showed findings consistent with posterior reversible encephalopathy syndrome. Complete blood count showed lymphoblasts, and the cause of his hypertension was determined to be renal infiltration of leukemia cells due to B-cell acute lymphoblastic leukemia.

Involvement of A13 dopaminergic neurons in prehensile movements but not reward in the rat.

Tyrosine hydroxylase (TH)-containing neurons of the dopamine (DA) cell group A13 are well positioned to impact known DA-related functions as their descending projections innervate target regions that regulate vigilance, sensory integration, and motor execution. Despite this connectivity, little is known regarding the functionality of A13-DA circuits. Using TH-specific loss-of-function methodology and techniques to monitor population activity in transgenic rats in vivo, we investigated the contribution of A13-DA neurons in reward and movement-related actions. Our work demonstrates a role for A13-DA neurons in grasping and handling of objects but not reward. A13-DA neurons responded strongly when animals grab and manipulate food items, whereas their inactivation or degeneration prevented animals from successfully doing so-a deficit partially attributed to a reduction in grip strength. By contrast, there was no relation between A13-DA activity and food-seeking behavior when animals were tested on a reward-based task that did not include a reaching/grasping response. Motivation for food was unaffected, as goal-directed behavior for food items was in general intact following A13 neuronal inactivation/degeneration. An anatomical investigation confirmed that A13-DA neurons project to the superior colliculus (SC) and also demonstrated a novel A13-DA projection to the reticular formation (RF). These results establish a functional role for A13-DA neurons in prehensile actions that are uncoupled from the motivational factors that contribute to the initiation of forelimb movements and help position A13-DA circuits into the functional framework regarding centrally located DA populations and their ability to coordinate movement.

Pain-resolving immune mechanisms in neuropathic pain.

Interactions between the immune and nervous systems are of central importance in neuropathic pain, a common and debilitating form of chronic pain caused by a lesion or disease affecting the somatosensory system. Our understanding of neuroimmune interactions in pain research has advanced considerably. Initially considered as passive bystanders, then as culprits in the pathogenesis of neuropathic pain, immune responses in the nervous system are now established to underpin not only the initiation and progression of pain but also its resolution. Indeed, immune cells and their mediators are well-established promoters of neuroinflammation at each level of the neural pain pathway that contributes to pain hypersensitivity. However, emerging evidence indicates that specific subtypes of immune cells (including antinociceptive macrophages, pain-resolving microglia and T regulatory cells) as well as immunoresolvent molecules and modulators of the gut microbiota-immune system axis can reduce the pain experience and contribute to the resolution of neuropathic pain. This Review provides an overview of the immune mechanisms responsible for the resolution of neuropathic pain, including those involved in innate, adaptive and meningeal immunity as well as interactions with the gut microbiome. Specialized pro-resolving mediators and therapeutic approaches that target these neuroimmune mechanisms are also discussed.

Croup associated with COVID-19: A case series.

Background: Croup encounters substantially decreased when the pandemic first began, specifically between March and September 2020, before croup cases dramatically spiked again with the Omicron variant. There is a dearth of information concerning children at risk for severe or refractory COVID-19-associated croup and their outcomes. Objective: The objective of this case series was to describe the clinical characteristics and outcomes of croup associated with the Omicron variant in children, with a focus on cases refractory to treatment. Methods: The case series includes children from birth to 18 years old who presented to a freestanding children's hospital emergency department in the Southeastern United States between December 1, 2021 and January 31, 2022 with a diagnosis of croup and a laboratory-confirmed diagnosis of COVID-19. We used descriptive statistics to summarize patient characteristics and outcomes. Results: Of the total 81 patient encounters, 59 patients (72.8%) were discharged from the ED, with one patient requiring two revisits to the hospital. Nineteen patients (23.5%) were admitted to the hospital, and three of these patients represented to the hospital after discharge from the hospital. Three patients (3.7%) were admitted to the intensive care unit, none of whom represented after discharge. Conclusions: This study reveals a wide age range of presentation as well as a relatively higher rate of admission and fewer coinfections compared to pre-pandemic croup. Reassuringly, the results also show a low postadmission intervention rate as well as a low revisit rate. We discuss four refractory cases to highlight nuances for management and disposition decisions.

Research priority setting in emergency care: A scoping review.

Objective: Priority areas for emergency care research are emerging and becoming ever more important. The objectives of this scoping review were to (1) provide a comprehensive overview of published emergency care priority-setting studies by collating and comparing priority-setting methodology and (2) describe the resulting research priorities identified. Methods: The Joanna Briggs Institute methodological framework was used. Inclusion criteria were peer-review articles available in English, published between January 1, 2008 and March 31, 2019 and used 2 or more search terms. Five databases (Scopus, AustHealth, EMBASE, CINAHL, and Ovid MEDLINE) were searched. REporting guideline for PRIority SEtting of health research (REPRISE) criteria were used to assess the quality of evidence of included articles. Results: Forty-five studies were included. Fourteen themes for emergency care research were considered within 3 overarching research domains: emergency populations (pediatrics, geriatrics), emergency care workforce and processes (nursing, shared decision making, general workforce, and process), and emergency care clinical areas (imaging, falls, pain management, trauma care, substance misuse, infectious diseases, mental health, cardiology, general clinical care). Variation in the reporting of research priority areas was evident. Priority areas to drive the global agenda for emergency care research are limited given the country and professional group-specific context of existing studies. Conclusion: This comprehensive summary of generated research priorities across emergency care provides insight into current and future research agendas. With the nature of emergency care being inherently broad, future priorities may warrant population (eg, children, geriatrics) or subspecialty (eg, trauma, toxicology, mental health) focus and be derived using a rigorous framework and patient engagement.

Lifespan differences in background functional connectivity of core cognitive large-scale brain networks.

Large-scale brain networks undergo functional reorganization over the course of the lifespan, with concurrent implications for cognition. Characterizing network connectivity during a task may provide complementary insight into cognitive development and aging, to that provided by resting-state. We assessed network background connectivity, which refers to connectivity that remains after task effects have been regressed out, during a visual memory-encoding task in a lifespan sample. More specifically we assessed the within- and between-network background connectivity of the default mode, salience, and frontoparietal networks. Within-network background connectivity of salience and frontoparietal networks differed between age groups, with late-life adults showing lower connectivity. We did not find an effect of age group in default mode network background connectivity, contrary to previous findings using resting-state. However, default mode between-network background connectivity with salience and frontoparietal networks was greater in mid-life and late-life adults than in younger age groups. Overall, our findings in a lifespan sample are in line with previous observations of age-related network de-differentiation. However, the lack of age effect in default mode network background connectivity suggests that background connectivity indeed represents a complementary measure to resting-state connectivity, providing a differential glance of network connectivity during a particular state.

Sex-specific transcriptome of spinal microglia in neuropathic pain due to peripheral nerve injury.

Neuropathic pain is a prevalent and debilitating chronic disease that is characterized by activation in glial cells in various pain-related regions within the central nervous system. Recent studies have suggested a sexually dimorphic role of microglia in the maintenance of neuropathic pain in rodents. Here, we utilized RNA sequencing analysis and in vitro primary cultures of microglia to identify whether there is a common neuropathic microglial signature and characterize the sex differences in microglia in pain-related regions in nerve injury and chemotherapy-induced peripheral neuropathy mouse models. While mechanical allodynia and behavioral changes were observed in all models, transcriptomic analysis of microglia revealed no common transcriptional changes in spinal and supraspinal regions and in the different neuropathic models. However, there was a substantial change in microglial gene expression within the ipsilateral lumbar spinal cord 7 days after chronic constriction injury (CCI) of the sciatic nerve. Both sexes upregulated genes associated with inflammation, phagosome, and lysosome activation, though males revealed a prominent global transcriptional shift not observed in female mice. Transcriptomic comparison between male spinal microglia after CCI and data from other nerve injury models and neurodegenerative microglia demonstrated a unique CCI-induced signature reflecting acute activation of microglia. Further, in vitro studies revealed that only male microglia from nerve-injured mice developed a reactive phenotype with increased phagocytotic activity. This study demonstrates a lack of a common neuropathic microglial signature and indicates distinct sex differences in spinal microglia, suggesting they contribute to the sex-specific pain processing following nerve injury.

Coral Genus Differentiation Based on Direct Analysis in Real Time-High Resolution Mass Spectrometry-Derived Chemical Fingerprints.

Coral reefs are one of the most biologically diverse ecosystems, and the accurate identification of the species is essential for diversity assessment and conservation. Current genus determination approaches are time-consuming and resource-intensive and can be highly subjective. To explore the hypothesis that the small-molecule profiles of coral are genus-specific and can be used as a rapid tool to catalogue and distinguish between coral genera, the small-molecule chemical fingerprints of the species Acanthastrea echinata, Catalaphyllia jardinei, Duncanopsammia axifuga, Echinopora lamellosa, Euphyllia divisa, Euphyllia paraancora, Euphyllia paradivisa, Galaxea fascicularis, Herpolitha limax, Montipora confusa, Monitpora digitata, Montipora setosa, Pachyseris rugosa, Pavona cactus, Plerogyra sinuosa, Pocillopora acuta, Seriatopora hystrix, Sinularia dura, Turbinaria peltata, Turbinaria reniformis, Xenia elongata, and Xenia umbellata were generated using direct analysis in real time-high resolution mass spectrometry (DART-HRMS). It is demonstrated here that the mass spectrum-derived small-molecule profiles for coral of different genera are distinct. Multivariate statistical analysis processing of the DART-HRMS data enabled rapid genus-level differentiation based on the chemical composition of the coral. Coral samples were analyzed with no sample preparation required, making the approach rapid and efficient. The resulting spectra were subjected to kernel discriminant analysis (KDA), which furnished accurate genus differentiation of the coral. Leave-one-out cross-validation (LOOCV) was carried out to determine the classification accuracy of each model and confirm that this approach can be used for coral genus attribution with prediction accuracies ranging from 86.67 to 97.33%. The advantages and application of the statistical analysis to DART-HRMS-derived coral chemical signatures for genus-level differentiation are discussed.

Predictive and motivational factors influencing anticipatory contrast: A comparison of contextual and gustatory predictors in food restricted and free-fed rats.

In anticipation of palatable food, rats can learn to restrict consumption of a less rewarding food type resulting in an increased consumption of the preferred food when it is made available. This construct is known as anticipatory negative contrast (ANC) and can help elucidate the processes that underlie binge-like behavior as well as self-control in rodent motivation models. In the current investigation we aimed to shed light on the ability of distinct predictors of a preferred food choice to generate contrast effects and the motivational processes that underlie this behavior. Using a novel set of rewarding solutions, we directly compared contextual and gustatory ANC predictors in both food restricted and free-fed Sprague-Dawley rats. Our results indicate that, despite being food restricted, rats are selective in their eating behavior and show strong contextually-driven ANC similar to free-fed animals. These differences mirrored changes in palatability for the less preferred solution across the different sessions as measured by lick microstructure analysis. In contrast to previous research, predictive cues in both food restricted and free-fed rats were sufficient for ANC to develop although flavor-driven ANC did not relate to a corresponding change in lick patterning. These differences in the lick microstructure between context- and flavor-driven ANC indicate that the motivational processes underlying ANC generated by the two predictor types are distinct. Moreover, an increase in premature port entries to the unavailable sipper - a second measure of ANC - in all groups reveals a direct influence of response competition on ANC development.

Effect of exercise on neuromuscular toxicity in oxaliplatin-treated mice.

INTRODUCTION/AIMS: Clinically, the chemotherapeutic agent oxaliplatin can cause peripheral neuropathy, impaired balance, and muscle wastage. Using a preclinical model, we investigated whether exercise intervention could improve these adverse conditions. METHODS: Mice were chronically treated with oxaliplatin alone or in conjunction with exercise. Behavioral studies, including mechanical allodynia, rotarod, open-field, and grip-strength tests, were performed. After euthanasia, multiple organs and four different muscle types were dissected and weighed. The cross-sectional area (CSA) of muscle fibers in the gastrocnemius muscle was assessed and gene expression analysis performed on the forelimb triceps muscle. RESULTS: Oxaliplatin-treated mice displayed reduced weight gain, mechanical allodynia, and exploratory behavior deficits that were not significantly improved by exercise. Oxaliplatin-treated exercised mice showed modest evidence of reduced muscle wastage compared with mice treated with oxaliplatin alone, and exercised mice demonstrated evidence of a mild increase in CSA of muscle fibers. DISCUSSION: Exercise intervention did not improve signs of peripheral neuropathy but moderately reduced the negative impact of oxaliplatin chemotherapy related to muscle morphology, suggesting the potential for exploring the impact of exercise on reducing oxaliplatin-induced neuromuscular toxicity in cancer patients.

The cannabinoid system and microglia in health and disease.

Recent years have yielded significant advances in our understanding of microglia, the immune cells of the central nervous system (CNS). Microglia are key players in CNS development, immune surveillance, and the maintenance of proper neuronal function throughout life. In the healthy brain, homeostatic microglia have a unique molecular signature. In neurological diseases, microglia become activated and adopt distinct transcriptomic signatures, including disease-associated microglia (DAM) implicated in neurodegenerative disorders. Homeostatic microglia synthesise the endogenous cannabinoids 2-arachidonoylglycerol and anandamide and express the cannabinoid receptors CB1 and CB2 at constitutively low levels. Upon activation, microglia significantly increase their synthesis of endocannabinoids and upregulate their expression of CB2 receptors, which promote a protective microglial phenotype by enhancing their production of neuroprotective factors and reducing their production of pro-inflammatory factors. Here, we summarise the effects of the microglial cannabinoid system in the CNS demyelinating disease multiple sclerosis, the neurodegenerative diseases Alzheimer's disease, Parkinson's disease and amyotrophic lateral sclerosis, chronic inflammatory and neuropathic pain, and psychiatric disorders including depression, anxiety and schizophrenia. We discuss the therapeutic potential of cannabinoids in regulating microglial activity and highlight the need to further investigate their specific microglia-dependent immunomodulatory effects.

Phosphodiesterase type 1 inhibition alters medial prefrontal cortical activity during goal-driven behaviour and partially reverses neurophysiological deficits in the rat phencyclidine model of schizophrenia.

Positive modulation of cAMP signalling by phosphodiesterase (PDE) inhibitors has recently been explored as a potential target for the reversal of cognitive and behavioural deficits implicating the corticoaccumbal circuit. Previous studies show that PDE type 1 isoform B (PDE1B) inhibition may improve memory function in rodent models; however, the contribution of PDE1B inhibition to impulsivity, attentional and motivational functions as well as its neurophysiological effects have not been investigated. To address this, we recorded single unit activity in medial prefrontal cortex (mPFC) and nucleus accumbens (NAc) in Lister Hooded rats treated with the PDE1B inhibitor Lu AF64386 and tested in the 5-choice serial reaction time task (5-CSRTT). We also asked whether PDE1B inhibition modulates neurophysiological deficits produced by subchronic phencyclidine (PCP) treatment, a rat pharmacological model of schizophrenia. Lu AF64386 significantly affected behavioural parameters consistent with a reduction in goal-directed behaviour, however without affecting accuracy. Additionally, it reduced mPFC neuronal activity. Pre-treatment with PCP did not affect behavioural parameters, however it significantly disrupted overall neuronal firing while increasing phasic responses to reward-predicting cues and disrupting mPFC-NAc cross-talk. The latter two effects were reversed by Lu AF64386. These findings suggest PDE1B inhibition may be beneficial in disorders implicating a dysfunction of the mPFC-NAc network.

Age moderation of the association between negative subsequent memory effects and episodic memory performance.

Negative subsequent memory effects in functional MRI studies of memory formation have been linked to individual differences in memory performance, yet the effect of age on this association is currently unclear. To provide insight into the brain systems related to memory across the lifespan, we examined functional neuroimaging data acquired during episodic memory formation and behavioral performance from a memory recognition task in a sample of 109 participants, including three developmental age groups (8-12, 13-17, 18-25 year-olds) and one additional group of older adults (55-85 year-olds). Young adults showed the highest memory performance and strongest negative subsequent memory effects, while older adults showed reduced negative subsequent memory effects relative to young adults. Across the sample, negative subsequent memory effects were associated with better memory performance, and there was a significant interaction between negative subsequent memory effects and memory performance by age group. Posthoc analyses revealed that this moderation effect was driven by a stronger association between negative subsequent memory effects and memory performance in young adults than children, and that neither children nor older adults showed a significant association. These findings suggest that negative subsequent memory effects may differentially support memory performance across a lifespan trajectory characterized by developmental maturation and support further investigation of this effect in aging.

Resting-state functional brain connectivity in a predominantly African-American sample of older adults: exploring links among personality traits, cognitive performance, and the default mode network.

The personality traits of neuroticism, openness, and conscientiousness are relevant factors for cognitive aging outcomes. The present study examined how these traits were associated with cognitive abilities and corresponding resting-state functional connectivity (RSFC) of the default mode network (DMN) in an older and predominantly minority sample. A sample of 58 cognitively unimpaired, largely African-American, older adults (M age = 68.28 ± 8.33) completed a standard RSFC magnetic resonance imaging sequence, a Big Five measure of personality, and delayed memory, Stroop, and verbal fluency tasks. Personality trait associations of within-network connectivity of the posterior cingulate cortex (PCC), a hub of the DMN, were examined using a seed-based approach. Trait scores were regressed on cognitive performance (delayed memory for neuroticism, Stroop for conscientiousness, and verbal fluency for openness). Greater openness predicted greater verbal fluency and greater RSFC between the PCC and eight clusters, including the medial prefrontal cortex, left middle frontal gyrus, and precuneus. Greater PCC-precuneus connectivity predicted greater verbal fluency. Neuroticism and conscientiousness did not significantly predict either cognitive performance or RSFC. Although requiring replication and elaboration, the results implicate openness as a contributing factor to cognitive aging via concomitant cognitive performance and connectivity within cortical hubs of the DMN and add to the sparse literature on these variables in a diverse group of older adults.

A Multi-Centered Case Series Highlighting the Clinical Use and Dosing of Lidocaine and Mexiletine for Refractory Cancer Pain.

Lidocaine infusion for pain control has been used for years. While some centers transition from continuous infusion lidocaine to oral mexiletine, there are no published studies to guide this conversion in pain and palliative care settings. This is a retrospective case series of 10 cancer patients across four institutions, with attention to dosing of both agents, and subsequent decrease in morphine-equivalent daily dosing (MEDD). The mean age was 55 years (range 34-78). The mean bolus dose of lidocaine was 1.6 mg/kg, infused over an average of 24 minutes, followed by a mean continuous infusion rate of 1.1 mg/kg/hr, and the infusion was continued for an average of 14.1 hours (range of 0.2 - 28 hours). The mean starting daily mexiletine dose was 400 mg (in 2-3 divided doses) and final dosing averaged 500 mg/day. The mean MEDD prior to starting lidocaine was 1118 mg/24 hours, which, by the time of final mexiletine dosing, was 882 mg/24 hours, a 21% MEDD reduction. The average hospital length of stay was 14 days. There was no lidocaine-induced toxicity and no lidocaine levels were obtained. Two of the 10 patients stopped mexiletine early, one from confusion four days after initiation of mexiletine, and the other after six weeks due to dizziness and visual changes. For cancer patients with suboptimal pain control on large doses of opioid, lidocaine infusion followed by oral mexiletine was well tolerated and effective.

Parental Perception of Care for Infants With Fever During Hospitalization.

OBJECTIVE: To assess parental perceptions regarding reason for and length of their infant's hospitalization and to understand family preferences for time of discharge. METHODS: Participants included parents of infants who were noncomplex, well-appearing infants, aged 7 to 60 days, and evaluated for fever without a source. A 5-question structured interview was administered over a 6-month period. RESULTS: Parents understood that fever necessitated admission for further diagnostic evaluation and that admissions would be no more than 48 hours if bacterial cultures were negative. Over one-third of patients' families preferred overnight discharge. DISCUSSION: Parents recognize reasons for admission and the rationale for length of stay. Preferences for time of discharge can serve as a starting point for shared decision-making between parents and providers.
