RESUMO
BACKGROUND: Local anesthesia (LA) is sparsely used in endovascular aneurysm repair (EVAR) despite short-term benefit, likely secondary to concerns over patient movement preventing accurate endograft deployment. The objective of this study is to examine the association between anesthesia type and endoleak, sac regression, reintervention, and mortality. METHODS: The Vascular Quality Initiative database was queried for all EVAR cases from 2014 to 2022. Patients were included if they underwent percutaneous elective EVAR with anatomical criteria within instructions for use of commercially approved endografts. Multivariable logistic regression with propensity score weighting was used to determine the association between anesthesia type on the risk of any endoleak noted by intraoperative completion angiogram and sac regression. Multivariable survival analysis with propensity score weighting was used to determine the association between anesthesia type and endoleak at 1 year, long-term reintervention, and mortality. RESULTS: Thirteen thousand nine hundred thirty two EVARs met inclusion criteria: 1,075 (8%) LA and 12,857 (92%) general anesthesia (GA). On completion angiogram, LA was associated with fewer rates of any endoleaks overall (16% vs. 24%, P < 0.001). On multivariable analysis with propensity score weighting, LA was associated with similar adjusted odds of any endoleak on intraoperative completion angiogram (odds ratio [OR] 0.56, 95% confidence interval [CI] 0.47-0.68) as well as combined type 1a and type 1b endoleaks (OR 0.72, 95% CI 0.47-1.09). Follow-up computed tomography imaging at 1 year was available for 4,892 patients, 377 (8%) LA and 4,515 (92%) GA. At 1 year, LA was associated with similar rate of freedom from any endoleaks compared to GA (0.66 [95% CI 0.63-0.69] vs. 0.71 [95% CI 0.70-0.72], P = 0.663) and increased rates of sac regression (50% vs. 45%, P = 0.040). On multivariable analysis with propensity score weighting, LA and GA were associated with similar adjusted odds of sac regression (OR 1.22, 95% CI 0.97-1.55). LA and GA had similar rates of endoleak at 1 year (hazard ratio [HR] 0.14, 95% CI 0.63-1.07); however, LA was associated with decreased hazards of combined type 1a and 1b endoleaks at 1 year (HR 0.87, 95% CI 0.80-0.96). LA and GA had similar adjusted long-term reintervention rate (HR 0.77, 95% CI 0.44-1.38) and long-term mortality (HR 1.100, 95% CI 079-1.25). CONCLUSIONS: LA is not associated with increased adjusted rates of any endoleak on completion angiogram or at 1-year follow-up compared to GA. LA is associated with decreased adjusted rates of type 1a and type 1b endoleak at 1 year, but similar rates of sac regression, long-term reintervention, and mortality. Concerns for accurate graft deployment should not preclude use of LA and LA should be increasingly considered when deciding on anesthetic type for standard elective EVAR.

BACKGROUND AND AIMS: Specialist nutritional support is important during treatment for oesophagogastric (OG) cancer yet current practice remains unstandardised across the UK. The National Oesophagogastric Nutrition Audit (NONA) aimed to describe the current landscape of OG dietetic services in the UK and Ireland, with a specific focus on resource allocation, barriers to dietetic support, and the provision of support throughout the cancer pathway. METHODS: Tertiary cancer units, secondary care, and community services across the UK and Ireland were invited to complete a 28-point electronic questionnaire. Team leaders and senior specialist OG dietitians were the target respondents. All data points were peer-reviewed, piloted, and revised by the NONA steering committee before distribution. Data points covered a range of areas related to resources, skill mix, provision of support throughout the cancer pathway, and involvement with national audit and research. RESULTS: Complete responses were received from 50 individual units (tertiary surgical units, n = 35 and tertiary oncology units, n = 10). Secondary care and community services were underrepresented (n = 5). Of the units proving tertiary cancer care, the majority (77%) agreed or strongly agreed they were able to provide adequate nutritional care in the post-operative period. However, confidence dropped significantly in the early diagnostic phase and in the neoadjuvant period, with 52% and 67% of tertiary units disagreeing that they could provide adequate dietetic support during these parts of the cancer pathway, respectively. Inadequate funding, understaffing, and the prioritisation of inpatients were commonly reported barriers. There was significant variation in practice regarding nutritional assessment, service structure, and staffing resource allocation across specialist units. CONCLUSION: The NONA survey provides a 'real-world' landscape of nutritional care for patients with OG cancer. Lack of funding, resource, and evidence-base may explain the variation seen in services provided across the UK. Further research and consensus is required to help standardise nutritional care, guide service specification, and improve nutritional outcomes for patients with OG cancer.

The Medical Home Clinic for Special Needs Children (MHCL) at Arkansas Children's Hospital provides comprehensive care oversight for children with medical complexity (CMC). The objective of this study is to evaluate parent perceptions of health care delivery outcomes after 12 months of enrollment in the MHCL. This is a prospective cohort study of parents of MHCL patients, who completed surveys at initial and 12-month visits. Surveys assessed parent health, child health and function, family stress, and overall satisfaction, using previously validated measures and scales. Paired analyses examined differences in measures between baseline and 12 months. One-hundred and twenty of 174 eligible parents completed the follow-up survey at 12 months. Respondents were 63% White/Caucasian, 90% biological parent, and 48% with an annual family income < $20,000. From baseline to 12 months, a greater number of respondents reported having a care plan (53% vs. 85%, p < .001); fewer respondents needed help with care coordination (78% vs. 31%, p < .001). No changes were seen in reports of having emotional needs met. Parents reported a decline in the physical subscale of the SF-12 Health-Related Quality of Life measure (49.1 vs. 46.4, p < .01), with those parents with ≥ 1 additional child with special needs reporting a marked decline (49.2 vs. 42.5, p < .001). No other changes in family impact were found. We conclude that comprehensive care oversight may improve care coordination for parents of CMC, but no association with improved parent health was found. Future studies should identify the factors that influence parental burden and tailor clinical interventions to address such factors.

OBJECTIVE: To evaluate the effect on all state Medicaid costs of a children's hospital-based multidisciplinary clinic that provides comprehensive and coordinated care for medically complex children. DESIGN: Before-after intervention study. Patients' health care costs for up to 1 year before enrollment in the clinic were compared with patients' health care costs for up to 1 year after enrollment in the clinic. Patients were enrolled in our study from August 2006 to May 2008. SETTING: Tertiary care children's hospital in a rural state. PARTICIPANTS: A total of 225 medically complex children who had at least 2 chronic medical conditions and who were followed up by at least 2 pediatric subspecialists. INTERVENTION: Multidisciplinary teams ensure that each patient receives all the necessary medical, nutritional, and developmental care and that there is improved coordination of care with primary care providers, subspecialists, hospitalists, and community-based services. MAIN OUTCOME MEASURES: Using Arkansas Medicaid claims data, we examined the medical costs for all outpatient, inpatient, emergency department, and prescription drug claims. Costs were calculated on a per month per patient basis and summarized for annual costs. RESULTS: The mean annual cost per patient per month decreased by $1766 for inpatient care (P < .001) and by $6.00 for emergency department care (P < .001). Although the cost per patient per month for outpatient claims (P < .05) and prescriptions (P < .001) increased, the overall cost to Medicaid per patient per month decreased by $1179 (P < .001). CONCLUSIONS: This hospital-based multidisciplinary clinic resulted in a significant decrease in total Medicaid costs for medically complex children.

Geranylgeranylation is critical to the function of several proteins including Rho, Rap1, Rac, Cdc42, and G-protein gamma subunits. Geranylgeranyltransferase type I (GGTase-I) inhibitors (GGTIs) have therapeutic potential to treat inflammation, multiple sclerosis, atherosclerosis, and many other diseases. Following our standard workflow, we have developed and rigorously validated quantitative structure-activity relationship (QSAR) models for 48 GGTIs using variable selection k nearest neighbor (kNN), automated lazy learning (ALL), and partial least squares (PLS) methods. The QSAR models were employed for virtual screening of 9.5 million commercially available chemicals, yielding 47 diverse computational hits. Seven of these compounds with novel scaffolds and high predicted GGTase-I inhibitory activities were tested in vitro, and all were found to be bona fide and selective micromolar inhibitors. Notably, these novel hits could not be identified using traditional similarity search. These data demonstrate that rigorously developed QSAR models can serve as reliable virtual screening tools, leading to the discovery of structurally novel bioactive compounds.

To investigate whether growth status in infants and toddlers affects processes involved in speech perception and discrimination, cortical event-related potentials (ERPs) to consonant-vowel syllables were recorded from 48 healthy babies: 26 low in growth status (LGS, < 25 th percentile in growth measures) and from 22 normal in growth status (NGS, 25t--75 th percentile in growth measures). Food records indicated no significant differences in the amounts of various nutrients consumed in the two groups, but LGS babies consumed slightly more of most nutrients than NGS babies. In response to speech stimuli (either /pa/ or /ba/ presented with 20 and 80% randomized occurrence), brain ERPs showed two prominent post-stimulus components: a large positive wave peaking at about 484 msec and a negative but positive going slow wave (SW) between 867 and 1199 msec. Principal components analysis followed by promax rotation revealed four additional important components. Maximum peak and latency values-for these components showed that NGS and LGS babies differed from one another on all measures in either amplitude, latency, or both. Comparing the two groups of babies, only the LGS group demonstrated a deficit in the phonetic discrimination of speech sounds. The growth deficiencies of the LGS group could not be attributed to the lack of an adequate diet. These negative findings are present in babies generally considered to be healthy (lowest 10-25% in growth measures). This underscores the need for research examining in more detail the relationship between growth status and cognitive growth.

CONTEXT: National and state efforts to increase folic acid awareness and use may not be reaching large segments of the population. PURPOSE: This study examines folic acid awareness and use among women of childbearing age in a representative, economically at-risk rural sample and identifies factors that influence awareness and use. METHODS: A cross-sectional random digit dialing telephone survey was completed with a representative sample of 646 women aged 14-45 years in 36 counties of the lower Mississippi Delta. Folic acid awareness and supplement use were estimated by percentages weighted to reflect the 36-county population. Pregnancy intentions and the ability to become pregnant were used to predict awareness and use among a subsample of sexually active women. FINDINGS: Compared to national samples, Delta women were less likely to have heard of folic acid (75% vs 64%) or to take a regular (5-7 days/wk) folic acid supplement (34% vs 22%). The proportion of women who took regular folic acid supplements was very low among some subgroups: African Americans (14%), those 14-19 years of age (12%), and those with low incomes (13%) and low educational levels (14%). Of the women who reported being sexually active, the ability to become pregnant more than doubled their likelihood of regular supplement use. CONCLUSIONS: The national folic acid campaign has not reached many women in the rural Mississippi Delta. A new mode of folic acid education is needed that is focused on low-income and young women and women not planning pregnancies. In the Delta and similar geographic regions, health care providers, black church leaders, and youth group leaders could be valuable advocates for folic acid.
