RESUMEN
BACKGROUND AND OBJECTIVES: Vascular disease is a known risk factor for Alzheimer's disease (AD). Endothelial dysfunction has been linked to reduced cerebral blood flow. Endothelial nitric oxide synthase pathway (eNOS) upregulation is known to support endothelial health. This single-center, proof-of-concept study tested whether the use of three medications known to augment the eNOS pathway activity improves cognition and cerebral blood flow (CBF). METHODS: Subjects with mild AD or mild cognitive impairment (MCI) were sequentially treated with the HMG-CoA reductase synthesis inhibitor simvastatin (weeks 0-16), L-arginine (weeks 4-16), and tetrahydrobiopterin (weeks 8-16). The primary outcome of interest was the change in CBF as measured by MRI from baseline to week 16. Secondary outcomes included standard assessments of cognition. RESULTS: A total of 11 subjects were deemed eligible and enrolled. One subject withdrew from the study after enrollment, leaving 10 subjects for data analysis. There was a significant increase in CBF from baseline to week 8 by ~13% in the limbic and ~15% in the cerebral cortex. Secondary outcomes indicated a modest but significant increase in the MMSE from baseline (24.2±3.2) to week 16 (26.0±2.7). Exploratory analysis indicated that subjects with cognitive improvement (reduction of the ADAS-cog 13) had a significant increase in their respective limbic and cortical CBF. CONCLUSIONS: Treatment of mild AD/MCI subjects with medications shown to augment the eNOS pathway was well tolerated and associated with modestly increased cerebral blood flow and cognitive improvement. TRIAL REGISTRATION: This study is registered in https://www. CLINICALTRIALS: gov ; registration identifier: NCT01439555; date of registration submitted to registry: 09/23/2011; date of first subject enrollment: 11/2011.

BACKGROUND: Sodium nitrite has been reported to be effective in reducing chronic peripheral pain. OBJECTIVES: To evaluate the safety and efficacy of 40 and 80 mg, BID, of an oral sustained release formulation of sodium nitrite (SR-nitrite) in patients suffering from diabetic neuropathy, and to determine whether SR-nitrite would reduce the frequency of headaches reported previously by subjects receiving the same doses of an immediate release formulation. STUDY DESIGN: Phase II, single-center, randomized, double-blind, placebo controlled clinical trial. SETTING: The Ohio Pain Clinic and Kettering Medical Center. METHODS: Twenty-four patients were randomized to 40 mg or 80 mg SR-nitrite or placebo twice daily for 12 weeks. The primary objective was to determine whether headaches would be reduced using SR-nitrite. The primary efficacy endpoint was the mean difference in the change of the Neuropathic Pain Symptom Inventory (NPSI) pain score from baseline to that reported after 12 weeks of treatment. Secondary endpoints included changes from baseline for the Brief Pain Inventory (BPI) Scale, the RAND 36 questionnaire, Short Form McGill Questionnaire, daily patient reported score for neuropathic pain, changes in HbA1c, PulseOx and quantitative sensory testing. RESULTS: The number of subjects reporting adverse events and the number of adverse events did not change with dose. There were no reports of treatment-related headaches. Although no significant differences were identified in patient responses to the questionnaires, a trend was observed. In the NPSI assessment, patients in the 40 mg and 80 mg dose group reported a 12.7% and 22.0% reduction in pain, respectively, compared to an 8.4% reduction by patients in the placebo group. A trend was also observed with the BPI total severity score. However, the 40 mg dosing group reported the greatest reduction in pain using the McGill Pain index and via patient logs of daily pain scores, where the mean of pain scores reported by subjects in the 40 mg group dropped by day 41 and generally stayed lower than the mean of scores reported by subjects in either of the other two groups. Patients in the 80 mg SR-nitrite group had an improvement in both Nerve Sensory Conductance and Nerve Sensory Velocity. No changes were observed in HbA1c levels or PulseOx. LIMITATIONS: Small sample size. CONCLUSION: Sustained release sodium nitrite prevents the prevalent reports of headaches by patients treated with an immediate release formulation of sodium nitrite. In a previous study of patients with peripheral arterial disease (PAD), 40 mg BID treatment led to a statistically significant reduction in reported pain, similar trends were observed at the end of the trial period for most of the pain questionnaires used in the study. The 80 mg BID treatment had the more pronounced affect on bioactivity (quantitative sensory testing), which was similar to the PAD study, where this dose group had the greatest improvement in FMD {AU: spell out FMD}. The ability to alleviate pain with BID treatment of SR-nitrite offers promise for a new non-addictive, non-sedating treatment of chronic pain and warrants further study. KEY WORDS: Diabetes, diabetic neuropathy, neuropathic pain, peripheral neuropathy, sodium nitrite.

INTRODUCTION: The mechanism triggering degeneration in Alzheimer's disease (AD) remains uncertain. Therapeutic failure following amyloid ß (Aß) removal casts doubt on amyloid neurotoxicity per se as the primary cause of AD. Impaired microvascular function has been suggested as an alternative etiology. People with Down syndrome (DS) develop Alzheimer's pathology, but whether microvascular impairment also occurs in DS (as in AD) is unknown. METHODS: We examined brain microvasculature in five DS subjects with AD-type histopathology, seven AD cases, and seven controls without AD-type pathology. We counted microvessels in five anatomic regions and assessed endothelial integrity by CD31 immunohistochemistry. RESULTS: Microvascular numbers and endothelial integrity were significantly diminished in DS brains compared with controls and were similar to AD brains. DISCUSSION: People with DS and trisomy 21 produce a large amount of Aß. If Alzheimer's pathology occurred in DS without microvascular loss or endothelial impairment, a direct neurotoxic Aß mechanism would be supported and microvascular impairment rejected. The observation of microvascular impairment in DS with Alzheimer's disease changes fails to reject the microvascular hypothesis and provides some support for this potential mechanism of injury.

OBJECTIVE: Patients are frequently prescribed multiple antipsychotic medications, leading to higher healthcare costs and increased risk for side effects. The efficacy of multiple versus single antipsychotics to prevent acute relapse, measured by incidence of inpatient readmission, is investigated in Arizona, USA. METHOD: A retrospective chart review compared socio-demographic and clinical data from 1,010 patients discharged on a single and 377 discharged on multiple antipsychotic medications. Case management records were reviewed for readmission within one year of discharge. RESULTS: Younger age, diagnosis of Schizophrenia or Schizoaffective Disorder, prescription of mood stabilizer, shorter length of stay, and discharge to residential treatment or crisis recovery unit were associated with multiple antipsychotics at discharge. Readmission rates of the single (13.7%) versus multiple (15.9%) antipsychotic groups were not statistically different (p=0.286). Logistic regression analysis established that only age (younger) and the prescription of a mood stabilizer at discharge were significant predictors for increased risk for readmission (p=0.010 and p=0.049, respectively). A Cox survival analysis supported these findings. CONCLUSIONS: Concomitant antipsychotic polypharmacy at discharge did not reduce readmission risk over a one-year period. Given the increased risk of side effects and financial costs of polypharmacy, this study did not provide evidence to support this practice. Strikingly, only two variables predicted readmission risk, younger age and prescription of mood stabilizer. Although practitioners should follow practice guidelines more closely to prevent unnecessary exposure to potentially lethal side effects of antipsychotic polypharmacy, further studies are needed to better identify patients at high risk for readmission.

With increasing numbers of people with Alzheimer's and other dementias across the globe, many countries have developed national plans to deal with the resulting challenges. In the United States, the National Alzheimer's Project Act, signed into law in 2011, required the creation of such a plan with annual updates thereafter. Pursuant to this, the US Department of Health and Human Services (HHS) released the National Plan to Address Alzheimer's Disease in 2012, including an ambitious research goal of preventing and effectively treating Alzheimer's disease by 2025. To guide investments, activities, and the measurement of progress toward achieving this 2025 goal, in its first annual plan update (2013) HHS also incorporated into the plan a set of short, medium and long-term milestones. HHS further committed to updating these milestones on an ongoing basis to account for progress and setbacks, and emerging opportunities and obstacles. To assist HHS as it updates these milestones, the Alzheimer's Association convened a National Plan Milestone Workgroup consisting of scientific experts representing all areas of Alzheimer's and dementia research. The workgroup evaluated each milestone and made recommendations to ensure that they collectively constitute an adequate work plan for reaching the goal of preventing and effectively treating Alzheimer's by 2025. This report presents these Workgroup recommendations.

OBJECTIVE: The primary goal of this project was to create and evaluate the utility, validity, and reliability of an instrument assessing resident performance during child and adolescent psychiatry (CAP) training. In three stages, the instrument was developed and evaluated for utility in assessing skills critical to CAP. Items on the Global Assessment Evaluation (GAE) were derived from the six core competencies identified by the American College of Graduate Medical Education (ACGME). Secondary goals included producing an instrument that could be used by other CAP training programs and describing a process that could be followed by training programs to create their own assessment instruments. METHODS: Faculty members developed a CAP resident performance evaluation instrument. In a three-stage process, faculty utilized the tool to evaluate residents during and after rotations. Statistical findings guided revisions to improve the utility and reliability of the instrument. For the final version of the GAE, intra-class correlation coefficients were calculated to assess inter-rater reliability, and Principal Components Analysis provided further insight into the dimensions of resident assessment. RESULTS: The final version of the GAE showed overall and construct validity by capturing significant differences among residents and matched faculty members' overall impressions of resident performance. Intra-class correlation coefficient values for the overall score (0.945) and individual scales showed good reliability. Resident performance was not correlated with rotation site or model of care. CONCLUSIONS: The GAE has proved a valuable instrument in tracking the progress, strengths, and weaknesses in resident performance over the course of training. Data from multiple evaluations over time provide useful information about resident performance in a way that one or few evaluations does not. This finding is consistent with the practice of semiannual reviews and the new Clinical Competency Committees, both of which are required by the ACGME.

The "amyloid hypothesis" has dominated Alzheimer research for more than 20 years, and proposes that amyloid is the toxic cause of neural/synaptic damage and dementia. If correct, decreasing the formation or removing amyloid should be therapeutic. Despite discrepancies in the proposed mechanism, and failed clinical trials, amyloid continues to be considered the cause of a degenerative cascade. Alternative hypotheses must explain three features: (i) why amyloid toxicity is not the etiology of Alzheimer's disease (AD), (ii) what alternative mechanisms cause the degeneration and dementia of AD, and (iii) why increased amyloid accumulates in the brain in AD. We propose that AD, which occurs in elderly, already vulnerable brains, with multiple age-related changes, is precipitated by impaired microvascular function, resulting primarily from decreased Notch-related angiogenesis. With impaired microvasculature, a lack of vascular endothelial-derived trophic factors and decreased cerebral blood flow cause the atrophy of neural structures. Therapeutic strategies should focus on supporting normal angiogenesis.

BACKGROUND: Streamlining the triage process is the key in improving emergency department (ED) workflow. Our objective was to determine if parents of pediatric ED patients in, low-literacy, inner-city hospital, who used the audio-assisted bilingual (English/Spanish) self-triage kiosk, were able to enter their child's medical history data using a touch screen panel with greater speed and accuracy than routine nurse-initiated triage. METHODS: Parent/child dyads visiting the pediatric ED for nonurgent conditions (February to April 2012) were randomized prospectively to self-triage kiosk group (n = 200) and standard nurse triage group (n = 200). Both groups underwent routine nurse-initiated triage that included verbal elicitation of basic medical history and manual entry into patients' electronic medical records. RESULTS: The kiosk user was a parent in 88.5% of the cases, a patient (range, 11-17 years) in 9.5% of the cases, and a proxy user (sibling or friend) in 2% of the cases. Language choice for kiosk use was equally distributed (English vs Spanish, 50.5% vs 49.5%). The mean (SD) time to enter medical history data by the kiosk group was significantly shorter than the standard nurse triage group (94.38 [38.61] vs 126.72 [62.61] seconds; P < 0.001). Significant inverse relationship was observed between parent education level and kiosk usage time (r = -0.26; P < 0.001). The mean inaccuracies were significantly lower for kiosk group (P < 0.05) in areas of medical, medication and immunization histories, and total discrepancy score. CONCLUSIONS: Kiosk triage enabled users to enter basic medical triage history data quickly and accurately in an ED setting with future potential for its wider use in improving ED workflow efficiency.

To determine predictors of serious bacterial infections in pediatric burn patients with fever (core temp ≥38.5°C), the authors conducted a retrospective review of medical records of pediatric (0-18 years) patients admitted to the Arizona Burn Center between 2008 and 2011 with greater than 5% TBSA and inpatient hospitalization for ≥72 hours. The study group comprised patients with a febrile episode during their inpatient stay. Serious bacterial infection (the primary outcome variable) was defined as: bacteremia, urinary tract infection, meningitis (blood, urine, or cerebrospinal fluid culture positive for a pathogen respectively), pneumonia, line, and wound infection. A generalized estimating equation analysis was done to predict the presence or absence of serious bacterial infection. Of 1082 pediatric burn patients hospitalized during the study period, 353 met the study eligibility criteria. A total of 108 patients (30.6%) had at least one fever episode (fever group). No difference in demographic characteristics was noted between the fever and no-fever groups; significant differences were observed for: third-degree TBSA, second-degree TBSA, total operating room visits, length of stay, Injury Severity Score, and death. A total of 47.2% of the patients had one or more episodes of fever with serious bacterial infection. In a generalized estimating equation predictive model, presence of a central line, second-, and third-degree TBSA were predictive of serious bacterial infection in burn patients with fever. In this study, individual clinical variables such as tachypnea and tachycardia were not predictive of serious bacterial infections, but the presence of a central line, and larger TBSA were significant predictors of serious bacterial infections. Younger age (P =.08) and ventilator support (P =.057) also approached significance as predictors of serious bacterial infections.

OBJECTIVES: The presence of free intraperitoneal fluid on diagnostic imaging (sonography or computed tomography [CT]) may indicate an acute inflammatory process in children with abdominal pain in a nontraumatic setting. Although clinical outcomes of pediatric trauma patients with free fluid on diagnostic examinations without evidence of solid-organ injury have been studied, similar studies in the absence of trauma are rare. Our objective was to study clinical outcomes of children with acute abdominal pain of nontraumatic etiology and free intraperitoneal fluid on diagnostic imaging (abdominal/pelvic sonography, CT, or both). METHODS: We conducted a retrospective review of medical records of children aged 0 to 18 years presenting to a pediatric emergency department with acute abdominal pain (nontraumatic) between April 2008 and March 2009. Patients with intraperitoneal free fluid on imaging were divided into 2 groups: group I, imaging suggestive of an intra-abdominal surgical condition such as appendicitis; and group II, no evidence of an acute surgical condition on imaging, including patients with equivocal studies. Computed tomograms and sonograms were reviewed by a board-certified radiologist, and the free fluid volume was quantitated. RESULTS: Of 1613 patients who underwent diagnostic imaging, 407 were eligible for the study; 134 (33%) had free fluid detected on diagnostic imaging. In patients with both sonography and CT, there was a significant correlation in the free fluid volume (r = 0.79; P < .0005). A significantly greater number of male patients with free fluid had a surgical condition identified on imaging (57.4% versus 25%; P < .001). Children with free fluid and an associated condition on imaging were more likely to have surgery (94.4% versus 6.3%; P < .001). CONCLUSIONS: We found clinical outcomes (surgical versus nonsurgical) to be most correlated with a surgical diagnosis on diagnostic imaging and not with the amount of fluid present.

BACKGROUND: Pregnancy is becoming more common in residency, and about 80% of residents are female. This leads to questions of breastfeeding, work demands, and perception of burden by colleagues. This study was designed to assess experiences of (1) breastfeeding obstetrics residents and (2) their colleagues. MATERIALS AND METHODS: This was a cross-sectional study of obstetrics and gynecology residents. Residents were categorized into experience with or no experience with breastfeeding to determine differences. RESULTS: Responses were obtained from 404 residents in obstetrics. Breastfeeding is common, with 90% of residents knowing a breastfeeding resident and 22% of residents reporting personal experience with breastfeeding. Breastfeeding residents (n=89) felt support from their faculty and fellow residents. More than one in three breastfeeding mothers felt they placed extra demands on colleagues, despite 80% of colleagues reporting that they did not feel that breastfeeding colleagues placed extra demands. A breastfeeding policy was important to 85% of residents, but only 7% believed their program had one. Two-thirds of breastfeeding residents struggled with low milk supply and stopped breastfeeding early. CONCLUSIONS: Despite high levels of perceived support from faculty/fellow residents, breastfeeding residents struggle with low milk supply and work demands that lead to early discontinuation.

OBJECTIVE: The objective of this study was to investigate whether the use of a silver-containing hydrofiber dressing to pack abscess cavity after incision and drainage (I & D) leads to faster wound healing and less pain. METHODS: Patients 18 years or older visiting the emergency department with cutaneous abscesses, requiring I & D, were randomly assigned to the intervention (Aquacel Ag; ConvaTec, Skillman, New Jersey) or standard care (iodoform) group between April 2008 and May 2009. Patients were followed up 48 to 72 hours and 10 to 14 days after the initial visit. Primary outcomes were the proportion of patients with greater than 30% reduction in surface area of abscess or cellulitis at first follow-up. RESULTS: Ninety-two patients were enrolled prospectively and randomly assigned to the Aquacel Ag or the iodoform groups; mean age was 38.0 (SD, 12.0) years; 49 patients were in the Aquacel Ag and 43 were in iodoform groups, respectively. There were no differences in demographic and clinical characteristics between groups. Logistic regression analysis showed that the intervention (Aquacel Ag) was independently associated with greater than 30% reduction in surface area of abscess (P = .002) but not in cellulitis at first follow-up. There was also significant decrease in pain intensity perceived by patients in the Aquacel Ag group based on the mean change in Facial Pain Scale scores between the initial visit and first follow-up. CONCLUSION: In patients with cutaneous abscesses, use of an antimicrobial hydrofiber ribbon dressing for packing was associated with faster wound healing and reduction in perceived pain in comparison with use of iodoform dressing.

The purpose of this study was to compare influenza vaccination rates of pregnant women in a public safety-net health system to national coverage rates during the 2009-2010 pandemic influenza season. A chart review of a random sample of deliveries was undertaken to determine rates of coverage and predictors of vaccine coverage of women who obtained prenatal care and delivered in our health system. Rates were calculated from deliveries from when the vaccine was first available through April 30, 2010. Coverage rates were 54% for the seasonal influenza vaccine and 51% for the H1N1 vaccine. Race/ethnicity, insurance status and language spoken did not predict the receipt of either vaccine. When we included only births which occurred through March 12, 2010, as was done in a large population-based study, the rates were 61% and 59%, respectively. Our rates are about 10% higher than the rates reported in that study. Our comprehensive strategy for promoting vaccine coverage achieved higher vaccination rates in a safety-net health system, which serves groups historically less likely to be vaccinated, than those reported for the pregnant population at large.
RESUMEN
STUDY OBJECTIVES: To describe a new approach to transgluteal pudendal neurolysis and transposition and to review the outcome in 10 patients who underwent repeat operation because of persistent pudendal neuralgia after failing to improve after initial surgical decompression. DESIGN: Retrospective analysis (Canadian Task Force classification II-3). SETTING: Academic chronic pelvic pain practice at St. Joseph's Hospital and Medical Center in Phoenix, Arizona. PATIENTS: Women and men with persistent pudendal neuralgia after undergoing transgluteal pudendal neurolysis and transposition. INTERVENTION: Transgluteal decompression of the pudendal nerve was performed in all 10 patients. In brief, a transgluteal incision was made, and the pudendal nerve was identified via a nerve integrity monitoring system. Adhesiolysis was performed from the piriformis muscle to the distal Alcock canal using a Zeiss NC-4 surgical microscope. The nerve was then enclosed in NeuraWrap Nerve Protector and coated with activated platelet-rich plasma. An ON-Q PainBuster catheter was place along the nerve into the Alcock canal, and 0.5% bupivacaine was infused at 2 mL/hr. The sacrotuberous ligament was repaired using an Achilles or gracillis cadaver ligament. The overlying subcutaneous tissue and skin were then closed. MEASUREMENTS AND MAIN RESULTS: From June 2008 to March 2010, 10 consecutive patients (7 women and 3 men; age range, 29-81 years) underwent repeat operation with transgluteal decompression of the pudendal nerve. Neuropathic pain was unilateral (n = 8) or bilateral (n = 2), in the clitoris or penis (30%), vulva or scrotum (70%), perineum (40%), and rectum (50%). Of the 10 patients, 1 patient was lost to follow-up. Mean follow-up was 23 months. Eight of 9 patients reported global improvement, with 2 patients reporting complete resolution of symptoms. One patient reported no change. Pain, as measured using an 11-point numerical scale, improved from a mean of 7.2 to 4.0 (p = .02), with 5 patients reporting clinically significant improvement (change, ≥2). Comfortable sitting or maximum time that the patient was able to sit without exacerbation of pain improved in 8 patients, with a change in median time of 5 to 45 minutes (p = .008). Change in the ability to sit correlated well with patient-reported global improvement (correlation coefficient, 0.86). No patient experienced worsening of symptoms. CONCLUSION: Patients with persistent pudendal neuralgia after surgical decompression may benefit from repeat operation via our novel approach. Ability to sit correlates well with reported improvement due to surgery.

BACKGROUND AND OBJECTIVES: There is no clear gold standard treatment for childhood posttraumatic stress disorder (PTSD). An annotated bibliography and meta-analysis were used to examine the efficacy of cognitive behavioral therapy (CBT) in the treatment of pediatric PTSD as measured by outcome data from the Child Behavior Checklist (CBCL). METHOD: A literature search produced 21 studies; of these, 10 utilized the CBCL but only eight were both 1) randomized; and 2) reported pre- and post-intervention scores. RESULTS: The annotated bibliography revealed efficacy in general of CBT for pediatric PTSD. Using four indices of the CBCL, the meta-analysis identified statistically significant effect sizes for three of the four scales: Total Problems (TP; -.327; p = .003), Internalizing (INT; -.314; p = .001), and Externalizing (EXT; -.192; p = .040). The results for TP and INT were reliable as indicated by the fail-safe N and rank correlation tests. The effect size for the Total Competence (TCOMP; -.054; p = .620) index did not reach statistical significance. LIMITATIONS: Limitations included methodological inconsistencies across studies and lack of a randomized control group design, yielding few studies for meta-analysis. CONCLUSIONS: The efficacy of CBT in the treatment of pediatric PTSD was supported by the annotated bibliography and meta-analysis, contributing to best practices data. CBT addressed internalizing signs and symptoms (as measured by the CBCL) such as anxiety and depression more robustly than it did externalizing symptoms such as aggression and rule-breaking behavior, consistent with its purpose as a therapeutic intervention.

The purpose of our study was to examine rates of consent to participate in research in voluntarily and involuntarily hospitalized psychiatric patients in order to evaluate factors that may influence the decision to participate in research. We used logistic regression models to evaluate differences and found that involuntary patients were less likely to consent to participate. After adjustment for covariates, we found that consent rates did not differ between the involuntary and voluntary population, but that lower Global Assessment of Functioning (GAF) scores and psychosis negatively affected the decision to consent to research. We discuss the implications of our findings.

In Maricopa County, Arizona, most defendants who are found not competent and not restorable (NCNR) are admitted involuntarily to an acute-care inpatient hospital. Many of these patients would most likely not have met the State's usual admission criteria for acute inpatient care had they not been evaluated in relation to a criminal offense. Is this group treated differently from their peers who are not involved in the criminal justice system? We examined records for 293 NCNR admissions, retrospectively, to assess their admission status and the outcomes of their commitment. We compared them to 280 matched cases of patients admitted involuntarily from the community (non-NCNR). The NCNR group met fewer admission criteria and received court-ordered treatment (COT) 22 percent more often than did the non-NCNR patients. The NCNR patients had longer hospital stays despite being found less dangerous to themselves or others than the community sample. Results suggest that NCNR individuals are treated differently from non-NCNR patients.
