Expanding Global Health Engagement through Multilateral Security Organizations.

INTRODUCTION: Many countries around the world employ defense capabilities in support of global health engagement (GHE) through bilateral and multilateral organizations. Despite this, there does not appear to be a strategic approach and implementation plan for U.S. DoD GHE in support of and through multilateral organizations. The purpose of this research is to identify which security multilateral organizations are engaged in GHE, as well as how and why. These findings could inform an interoperable approach for doing so going forward. METHODS: A systematic review was conducted to develop a list of multilateral security organizations and agreements which engage in GHE, or could potentially play a role in GHE. RESULTS: Of the 3,488 agreements and organizations identified, 15 met the inclusion criteria. Among them, 87% (13/15) of the multilateral organizations are regional and 13% (2/15) are international, all established between 1948 and 2020. The 15 organizations cover all DoD Geographical Combatant Commands. Among them, 20% (3/15) are a legally binding alliance, 73% (11/15) have a treaty, and 7% (1/15) have a diplomatic partnership. Twenty percent (3/15) have an explicit intent to improve health in either their mission statement or as part of their goals, priorities, and/or objectives. Eighty percent (12/15) engage in at least two GHE domains outlined in DoD Policy, 67% in three (10/15), and 47% in all four (7/15). The most common domain is humanitarian assistance and foreign disaster response at 100% (15/15) and least common is Nuclear, Chemical, and Biological Defense Programs at 53% (8/15). CONCLUSIONS: Although there is high demand for GHE, resourcing to enable implementation has not been prioritized. Therefore, multilateral organizations continue to support what is funded (e.g., disaster response) versus prioritizing capacity building or modifying authorities and appropriations to match demand. It is also worth noting most organizations included in this review support the European theater aligning to historical defense priorities, versus emerging threats in the Indo-Pacific region. Identifying a forum within these multilateral institutions to convene GHE policy makers and practitioners is a logical next step. The forums could guide and direct priorities, devise solutions, and implement best practices. Near term efforts could include GHE financing, governance, assurance, and technical assistance within and across multilateral institutions. Recent efforts highlight growth in both interest and action to support the variety of GHE activities regionally and internationally. As the United States seeks to reinforce multilateral institutions and uphold the international and rules-based order, employing GHE through multilateral cooperation could buttress efforts. Now is a perfect time given the sustained interest in global health, amplified value of allies and partners, and renewed emphasis placed on multilateral cooperation for the DoD to design a multilateral GHE strategy and seek Congressional support to resource it accordingly.

Advancing early relational health: a collaborative exploration of a research agenda.

Here, we introduce the Early Relational Health (ERH) Learning Community's bold, large-scale, collaborative, data-driven and practice-informed research agenda focused on furthering our mechanistic understanding of ERH and identifying feasible and effective practices for making ERH promotion a routine and integrated component of pediatric primary care. The ERH Learning Community, formed by a team of parent/caregiver leaders, pediatric care clinicians, researchers, and early childhood development specialists, is a workgroup of Nurture Connection-a hub geared toward promoting ERH, i.e., the positive and nurturing relationship between young children and their parent(s)/caregiver(s), in families and communities nationwide. In response to the current child mental health crisis and the American Academy of Pediatrics (AAP) policy statement promoting ERH, the ERH Learning Community held an in-person meeting at the AAP national headquarters in December 2022 where members collaboratively designed an integrated research agenda to advance ERH. This agenda weaves together community partners, clinicians, and academics, melding the principles of participatory engagement and human-centered design, such as early engagement, co-design, iterative feedback, and cultural humility. Here, we present gaps in the ERH literature that prompted this initiative and the co-design activity that led to this novel and iterative community-focused research agenda, with parents/caregivers at the core, and in close collaboration with pediatric clinicians for real-world promotion of ERH in the pediatric primary care setting.

On Protection of U.S. Forces From Global Health Threats: The Role of Health Security Advisors.

The coronavirus disease 2019 pandemic has exposed a health security gap within our nation and around the world. Recent national laws and policies have outlined the ends and means to improve health security. A decisive way is to achieve this objective is through health-related security cooperation efforts by increasing Health Services Support capacity.

Clinician Perceptions on Literacy Promotion in Pediatric Continuity Clinics.

OBJECTIVE: We describe LP perceptions of pediatric and internal medicine/pediatrics residents and faculty and determine the relationship between LP training and perceptions of LP. Reach Out and Read (ROR) is a widely implemented evidence-based literacy promotion (LP) intervention. Recent data have shown that there is variability in both LP training for pediatric residents and implementation of ROR. However, little is known about the perceptions regarding LP and the relationship with training. METHODS: Faculty and residents at participating sites completed an anonymous online survey on LP perceptions and training. Data were analyzed using descriptive statistics, chi-square tests, and logistic regression modeling. RESULTS: A total of 473 faculty and 1216 residents at 42 pediatric training programs participated. Faculty versus resident status was a significant predictor of almost all perception questions. Most faculty (65.3%) and residents (44.3%) completely agreed that it is the job of pediatricians to assess and encourage reading (P < .0001). Most faculty (69.6%) and residents (51.5%) completely agreed that LP is as important as advice about car seats, bike helmets, and "back-to-sleep" (P < .0001). More faculty (65.8%) than residents (46.6%) completely agreed with the statement "discussing sharing books with children at health supervision visits can be an effective early intervention strategy" (P < .0001). More faculty (34%) compared to residents (18.2%) completely agreed they felt confident modeling reading for parents during the visit (P < .0001). CONCLUSIONS: Faculty status predicted most favorable LP perceptions, while continuity clinic training and learning in-clinic from others predicted some favorable LP perceptions.

Implementation of a Novel Tool to Collect Milk Feeding Data on Infants in Primary Care Clinics.

We aimed to capture milk feeding type in real time in a racially and socioeconomically diverse population. An electronic tool to assess milk feeding type at every medical visit for children aged 0 to 2 years was designed and incorporated into nursing workflows. The Milk Box tool was successfully added to the electronic clinical workspace of a large health system. There were eight clinics, with diverse characteristics, which incorporated the use of the Milk Box tool over 12 months. Time to 50% uptake of Milk Box varied from 3 to 5 months. Time to >80% uptake varied from 6 to 8 months. Our results show that Milk Box can be quickly incorporated into a clinical workflow when the team is given appropriate training and support. The tool also allows a primary care practice to study local breast milk consumption trends and to provide both individualized and system-level lactation support.

Breakfast frequency and quality may affect glycemia and appetite in adults and children.

Observational studies of breakfast frequency in children and adults suggest an inverse (protective) association between the frequency of eating breakfast and the risk for obesity and chronic diseases such as type 2 diabetes. More prospective studies with stronger designs are needed, as are experimental studies on this topic. In addition, above and beyond breakfast frequency, the roles of dietary quality and composition need to be studied in the context of eating or skipping breakfast. Experimental studies are also necessary to rigorously test causality and biological mechanisms. Therefore, we conducted 2 pilot experimental studies to examine some of the effects of breakfast skipping and breakfast composition on blood glucose and appetite in children and adults. Our results suggest that breakfast frequency and quality may be related in causal ways to appetite controls and blood sugar control, supporting the hypothesis that the breakfast meal and its quality may have important causal implications for the risk of obesity and type 2 diabetes.

Influence of Early Lactation Assistance on Inpatient Exclusive Breastfeeding Rates.

BACKGROUND: Human milk feeding reduces the incidence and costs of several maternal and childhood illnesses. Initiation and success of human milk feeding are influenced by race, socioeconomic status, and family support. The influence of early in-hospital lactation assistance in breastfeeding success has been not well described. RESEARCH AIMS: We aimed to determine how suspected known factors influencing breastfeeding success influence in-hospital human milk feeding rates. Second, we aimed to examine how timing of lactation assistance is related to success of human milk feeding during the newborn hospitalization for healthy infants. METHODS: We conducted a retrospective cohort study of term infants born between January 1, 2014 and December 31, 2016 at a large tertiary academic hospital. We considered "success" to be 100% human milk feeding during the birth hospitalization, and compared differences in success by demographics, payor, race, and initial feeding preference. Influences of lactation assistance on success were analyzed using multivariable logistic regression. RESULTS: Mean success with exclusive human milk feeding among 7,370 infants was 48.9%, (n = 3,601). Successful participants were more likely to be 39-40 weeks' gestation (64.9%, n = 2,340), non-Hispanic/non-Latino (80.0%, n = 2,882), and using private insurance (69.2%, n = 2,491). Participants who had early feeding assisted by an International Board Certified Lactation Consultant (IBCLC) before being fed any formula were more likely to be successful than participants who had a feeding assisted by a non-IBCLC nurse (80% vs. 40% respectively). CONCLUSIONS: Success for exclusive human milk feeding during newborn hospitalization is strongly associated with several factors. Early intervention with IBCLCs can greatly improve breastfeeding success.

Clinician Experiences With Reach Out and Read: An Exploratory Qualitative Analysis.

BACKGROUND: Enhanced literacy and increased vocabulary related to Reach Out and Read (ROR) are well described. Less is known about clinicians' experience with the program. OBJECTIVE: Understand clinician experiences of implementing ROR. DESIGN/METHODS: This study was a collaboration between ROR and the Academic Pediatric Association's Continuity Research Network. Participants completed an anonymous online survey to evaluate Literacy Promotion activities and training, and were asked "What has been the most meaningful experience you have encountered with using ROR?" and "Is there anything else you would like to add?" Responses were evaluated by researchers and 4 themes were generated through discussion. All responses were divided and coded by researchers working in pairs and subsequently by all researchers until consensus was reached. Data were organized into themes. FINDINGS: Responses were provided by 592 (35%) participants. Qualitative analysis revealed benefits to participation in ROR within 4 themes: 1) Child/Family Impact (60%): "Seeing a child read for the first time" 2) Physician Impact (16%): "I... use the books... to connect with patients." 3) Impact on clinic practice (25%): "I... enjoy modeling for parents and use the books to assess... development" 4) Social Determinants of Health (2%): "The books... are an invaluable resource to our under-served population." CONCLUSION: Clinicians who implement ROR report positive impact on patients, families, and their own satisfaction and methods in practice. Clinicians value that the program addresses social determinants of health and facilitates developmental surveillance. Further study is needed to understand how clinician's perspectives affect and are affected by their experiences.

Weight-Related Behaviors of Children with Obesity during the COVID-19 Pandemic.

Background: During the coronavirus disease 2019 (COVID-19) pandemic, children and families have had to adapt their daily lives. The purpose of this study was to describe changes in the weight-related behaviors of children with obesity after the onset of the COVID-19 pandemic. Methods: Semistructured interviews (n = 51) were conducted from April to June 2020 with parents of children with obesity. Families were participants in a randomized trial testing a clinic-community pediatric obesity treatment model. During interviews, families described their experience during the COVID-19 pandemic, with a particular emphasis on children's diet, physical activity, sleep, and screen time behaviors. Rapid qualitative analysis methods were used to identify themes around changes in children's weight-related behaviors. Results: The mean child age was 9.7 (±2.8) years and the majority of children were Black (46%) or Hispanic (39%) and from low-income families (62%). Most parent participants were mothers (88%). There were differences in the perceived physical activity level of children, with some parents attributing increases in activity or maintenance of activity level to increased outdoor time, whereas others reported a decline due to lack of outdoor time, school, and structured activities. Key dietary changes included increased snacking and more meals prepared and consumed at home. There was a shift in sleep schedules with children going to bed and waking up later and an increase in leisure-based screen time. Parents played a role in promoting activity and managing children's screen time. Conclusions: The COVID-19 pandemic has created unique lifestyle challenges and opportunities for lifestyle modification. Clinical Trials ID: NCT03339440.

Literacy Promotion Training and Implementation in Pediatric Continuity Clinics.

BACKGROUND: Despite endorsement by the American Academy of Pediatrics, there are no national data on literacy promotion (LP) training and behaviors. OBJECTIVE: To describe LP training experiences and behaviors of pediatric and internal medicine/pediatrics residents and faculty nationally, and the association between LP training and behaviors. METHODS: The Academic Pediatric Association's Continuity Research Network and Reach Out and Read National Center sent an online survey to faculty and residents at participating Continuity Research Network clinics. Respondents were asked about LP training experiences and behaviors. Data were analyzed using descriptive statistics, chi-square tests, and logistic regression modeling. RESULTS: 473 faculty and 1216 residents at 42 institutions participated. More faculty than residents reported completing online Reach Out and Read training (63% vs 45%, P < .0001). More residents reported learning in clinic from others (92% vs 89%, P = .04). Training experiences did not differ otherwise. More faculty reported providing anticipatory guidance (87% vs 77%, P < .0001); modeling shared reading (69% vs 45%, P < .0001); and using books for developmental assessment (80% vs 62%, P < .0001). Both groups (97%) reported distributing books. The training modality most often endorsed as "very/extremely influential" was learning in clinic from others. Some LP behaviors were associated more strongly with online training while others were associated more strongly with in-person training. CONCLUSIONS: Online training and in-person training are both associated with high quality delivery of LP. Faculty members are more likely to have completed online training and to report engaging in the full range of recommended LP behaviors. These data have implications for LP training.

Identifying putative promoter regions of Hermansky-Pudlak syndrome genes by means of phylogenetic footprinting.

HPS is an autosomal recessive disorder characterized by oculocutaneous albinism and prolonged bleeding. Eight human genes are described resulting in the HPS subtypes 1-8. Certain HPS proteins combine to form Biogenesis of Lysosome-related Organelles Complexes (BLOCs), thought to function in the formation of intracellular vesicles such as melanosomes, platelet dense bodies, and lytic granules. Specifically, BLOC-2 contains the HPS3, HPS5 and HPS6 proteins. We used phylogenetic footprinting to identify conserved regions in the upstream sequences of HPS3, HPS5 and HPS6. These conserved regions were verified to have in vitro transcription activation activity using luciferase reporter assays. Transcription factor binding site analyses of the regions identified 52 putative sites shared by all three genes. When analysis was limited to the conserved footprints, seven binding sites were found shared among all three genes: Pax-5, AIRE, CACD, ZF5, Zic1, E2F and Churchill. The HPS3 conserved upstream region was sequenced in four patients with decreased fibroblast HPS3 RNA levels and only one HPS3 mutation in the coding exons and surrounding exon/intron boundaries; no mutation was found. These findings illustrate the power of phylogenetic footprinting for identifying potential regulatory regions in non-coding sequences and define the first putative promoter elements for any HPS genes.

Environmental Heat Exposure and Heat-Related Symptoms in United States Coast Guard Deepwater Horizon Disaster Responders.

OBJECTIVES: The response to the 2010 Deepwater Horizon oil spill was impacted by heat. We evaluated the association between environmental heat exposure and self-reported heat-related symptoms in US Coast Guard Deepwater Horizon disaster responders. METHODS: Utilizing climate data and postdeployment survey responses from 3648 responders, we assigned heat exposure categories based on both wet bulb globe temperature (WBGT) and heat index (HI) measurements (median, mean, maximum). We calculated prevalence ratios (PRs) and 95% confidence intervals (CIs) via adjusted Poisson regression models with robust error variance to estimate associations with reported heat-related symptoms. We also evaluated the association between use of personal protective equipment (PPE) and heat-related symptoms. RESULTS: Those in the highest WBGT median-based heat exposure category had increased prevalence of heat-related symptoms compared to those in the lowest category (PR=2.22 [95% CI: 1.61, 3.06]), and there was a significant exposure-response trend (P<.001). Results were similar for exposure categories based on WBGT and HI metrics. Analyses stratified by use of PPE found significantly stronger associations between environmental heat exposure and heat-related symptoms in those who did not use PPE (PR=2.23 [95% CI: 1.10, 4.51]) than in those who did (PR=1.64 [95% CI: 1.14, 2.36]). CONCLUSIONS: US Coast Guard Deepwater Horizon disaster responders who experienced higher levels of environmental heat had higher prevalences of heat-related symptoms. These symptoms may impact health, safety, and mission effectiveness. As global climate change increases the frequency of disasters and weather extremes, actions must be taken to prevent heat-related health impacts among disaster responders.

Mitogen-activated protein kinases as therapeutic targets in osteoarthritis.

PURPOSE OF REVIEW: The mitogen-activated protein (MAP) kinases are intracellular signaling proteins which play a central role in controlling the activity of pathways that regulate production and activity of multiple mediators of joint tissue destruction. The therapeutic potential of MAP kinase inhibition in osteoarthritis was reviewed. RECENT FINDINGS: Results from basic research studies support the role of MAP kinases as central mediators that regulate expression of proinflammatory cytokines and metalloproteinases but also as potential pain mediators as well. Cell culture and animal model studies suggest that inhibition of MAP kinases might slow progression of osteoarthritis but trials of MAP kinase inhibitors in humans with osteoarthritis have not yet been reported. Safety concerns of the currently available inhibitors have limited their initial use to trials in conditions considered more severe than osteoarthritis. SUMMARY: MAP kinase inhibition has the potential to slow disease progression in osteoarthritis and also might reduce pain; however, safety concerns have limited the use of general MAP kinase inhibitors in humans. Further understanding of the function of specific isoforms of the MAP kinases as well as upstream and downstream effectors may lead to the development of more specific inhibitors with less toxicity that could eventually be used as structure-modifying drugs for osteoarthritis.

Phonatory effects of airway dehydration: preliminary evidence for impaired compensation to oral breathing in individuals with a history of vocal fatigue.

PURPOSE: Airway drying is detrimental to phonation and is posited to exacerbate vocal fatigue. However, limited research has demonstrated the adverse phonatory effects of dehydration in speakers reporting vocal fatigue. We compared the negative phonatory consequences of short-term oral breathing at low, moderate, and high humidity in individuals reporting a history of vocal fatigue and control participants. METHOD: Females reporting a history of vocal fatigue (N = 8) and matched controls (N = 8) participated in a repeated-measures design over 3 different days. RESULTS: Oral breathing at low and moderate humidity increased phonation threshold pressure (PTP) to a greater extent in individuals reporting a history of vocal fatigue as compared to controls. Conversely, PTP did not increase in either participant group after oral breathing in a humid environment. Perceived phonatory effort (PPE) ratings were poorly correlated with PTP. CONCLUSIONS: The emergence of between-group differences in PTP at low and moderate but not high ambient humidity demonstrates that drying challenges might be detrimental to voice production in individuals with a history of vocal fatigue. Based on the phonatory effects of dehydration, we suggest that individuals reporting vocal fatigue may demonstrate impaired compensation to airway drying induced by short-term oral breathing.

Impact of a Modified Version of Baby-Led Weaning on Dietary Variety and Food Preferences in Infants.

The aim of this study was to determine whether food variety and perceived food preferences differ in infants following baby-led instead of traditional spoon-feeding approaches to introducing solids. A total of 206 women (41.3% primiparous) were recruited in late pregnancy from a single maternity hospital (response rate 23.4%) and randomized to Control (n = 101) or BLISS (n = 105) groups. All participants received government-funded Well Child care. BLISS participants also received support to exclusively breastfeed to 6 months and three educational sessions on BLISS (Baby-Led Weaning, modified to reduce the risk of iron deficiency, growth faltering, and choking) at 5.5, 7, and 9 months. Food variety was calculated from three-day weighed diet records at 7, 12, and 24 months. Questionnaires assessed infant preference for different tastes and textures at 12 months, and for 'vegetables', 'fruit', 'meat and fish', or 'desserts' at 24 months. At 24 months, 50.5% of participants provided diet record data, and 78.2% provided food preference data. BLISS participants had greater variety in 'core' (difference in counts over three days, 95% CI: 1.3, 0.4 to 2.2), 'non-core' (0.6, 0.2 to 0.9), and 'meat and other protein' (1.3, 0.8 to 1.9) foods at 7 months, and in 'fruit and vegetable' foods at 24 months (2, 0.4 to 3.6). The only differences in perceived food preferences observed were very small (i.e., <5% difference in score, at 12 months only). Infants following the modified Baby-Led Weaning were exposed to more varied and textured foods from an early age, but only an increased variety in 'fruit and vegetable' intake was apparent by two years of age.

Endogenous production of reactive oxygen species is required for stimulation of human articular chondrocyte matrix metalloproteinase production by fibronectin fragments.

The objective of the present study was to determine if reactive oxygen species (ROS) are required as secondary messengers for fibronectin fragment-stimulated matrix metalloproteinase (MMP) production in human articular chondrocytes. Cultured cells were stimulated with 25 microg/ml of the alpha5beta1 integrin-binding 110-kDa fibronectin fragment (FN-f) in the presence and absence of various antioxidants including Mn(III) tetrakis(4-benzoic acid)porphyrin (MnTBAP). FN-f stimulation significantly increased intracellular levels of ROS in articular chondrocytes. Pretreatment of cells with 250 microM MnTBAP or 40 mM N-acetyl-L-cysteine, but not inhibitors of nitric oxide synthase, completely prevented FN-f-stimulated MMP-3, -10, and -13 production. MnTBAP also blocked FN-f-induced phosphorylation of the MAP kinases and NF-kappaB-associated proteins and blocked activation of an NF-kappaB promoter-reporter construct. Overexpression of catalase, superoxide dismutase, or glutathione peroxidase also inhibited FN-f-stimulated MMP-13 production. Preincubation of chondrocytes with rotenone, an inhibitor of the mitochondrial electron transport chain, or nordihydroguaiaretic acid (NDGA), a selective 5-lipoxygenase inhibitor, partially prevented FN-f-stimulated MMP-13 production and decreased MAP kinase and NF-kappaB phosphorylation. These results show that increased production of ROS but not nitric oxide as obligatory secondary messengers in the chondrocyte FN-f signaling pathway leads to the increased production of MMPs, including MMP-13.

Characterization of power induced heating and damage in fiber optic probes for near-field scanning optical microscopy.

Tip-induced sample heating in near-field scanning optical microscopy (NSOM) is studied for fiber optic probes fabricated using the chemical etching technique. To characterize sample heating from etched NSOM probes, the spectra of a thermochromic polymer sample are measured as a function of probe output power, as was previously reported for pulled NSOM probes. The results reveal that sample heating increases rapidly to approximately 55-60 degrees C as output powers reach approximately 50 nW. At higher output powers, the sample heating remains approximately constant up to the maximum power studied of approximately 450 nW. The sample heating profiles measured for etched NSOM probes are consistent with those previously measured for NSOM probes fabricated using the pulling method. At high powers, both pulled and etched NSOM probes fail as the aluminum coating is damaged. For probes fabricated in our laboratory we find failure occurring at input powers of 3.4+/-1.7 and 20.7+/-6.9 mW for pulled and etched probes, respectively. The larger half-cone angle for etched probes ( approximately 15 degrees for etched and approximately 6 degrees for pulled probes) enables more light delivery and also apparently leads to a different failure mechanism. For pulled NSOM probes, high resolution images of NSOM probes as power is increased reveal the development of stress fractures in the coating at a taper diameter of approximately 6 microm. These stress fractures, arising from the differential heating expansion of the dielectric and the metal coating, eventually lead to coating removal and probe failure. For etched tips, the absence of clear stress fractures and the pooled morphology of the damaged aluminum coating following failure suggest that thermal damage may cause coating failure, although other mechanisms cannot be ruled out.

Insomnia and motor vehicle accident-related injuries, active component, U.S. Armed Forces, 2007-2016.

Insomnia is the most common sleep disorder in adults, and its incidence is increasing in the U.S. Armed Forces. A potential consequence of insomnia (including medications used to treat it) is increased risk of motor vehicle accidents (MVAs), which cause significant morbidity and mortality in service members. To examine the relationship between insomnia and MVA-related injuries in the U.S. Armed Forces, this retrospective cohort study compared incidence rates of MVA-related injuries from 2007 through 2016 between service members with diagnosed insomnia and an unexposed cohort. After adjustment for multiple covariates, service members with insomnia had more than double the rate of MVA-related injuries, compared to service members without insomnia (adjusted incidence rate ratio: 2.08; 95% CI: 1.95-2.22). A subanalysis of service members with insomnia during 2014-2016 found no difference in risk of MVA-related injury based on days' supply of sleep aid medications prescribed in 365 days following insomnia diagnosis. Insomnia is an important potential risk factor for MVAs in the military. Sleep health should be a component of MVA prevention efforts.

Awake High-Flow Extracranial to Intracranial Bypass for Complex Cerebral Aneurysms: Institutional Clinical Trial Results.

OBJECTIVE: Assess the potential added benefit to patient outcomes of "awake" neurological testing when compared with standard neurophysiologic testing performed under general endotracheal anesthesia. METHODS: Prospective study of 30 consecutive adult patients who underwent awake high flow extracranial to intracranial (HFEC-IC) bypass. Clinical neurological and neurophysiologic findings were recorded. Primary outcome measures were the incidence of stroke/cerebrovascular accident (CVA), length of stay, discharge to rehabilitation, 30-day modified Rankin scale score, and death. An analysis was also performed of a retrospective control cohort (n = 110 patients who underwent HFEC-IC for internal carotid artery (ICA) aneurysms under standard general endotracheal anesthesia). RESULTS: Five patients (16.6%) developed clinical awake neurological changes (4, contralateral hemiparesis; 1, ipsilateral visual changes) during the 10-minute ICA occlusion test. These patients had 2 kinks in the graft, 1 vasospasm, 1 requiring reconstruction of the distal anastomosis, and 1 developed blurring of vision that reversed after the removal of the distal permanent clip on the ICA. Three of these 5 patients had asynchronous clinical "awake" neurological and neurophysiologic changes. Two patients (7%) developed CVA. Median length of stay was 4 days. Twenty-eight of 30 patients were discharged to home. Median modified Rankin scale score was 1. There were no deaths in this series. Absolute risk reduction in the awake craniotomy group (n = 30) relative to control retrospective group (n = 110) was 7% for CVA, 9% for discharge to rehabilitation, and 10% for graft patency. CONCLUSIONS: Temporary ICA occlusion during HFEC-IC bypass for ICA aneurysms in conjunction with awake intraoperative clinical testing was effective in detecting a subset of patients (n = 3, 10%) in whom neurological deficit was not detected by neurophysiologic monitoring alone.
