RESUMO
This study examined the efficacy of CVLT-3 response bias (i.e., parametric and nonparametric response bias) indices in differentiating between a clinical sample with traumatic brain injury and a litigating sample with poor performance validity.Participants included 106 individuals, divided into two groups: clinical group with TBI (n = 56) and a litigating group who demonstrated inadequate performance validity (n = 50), as measured by failure on at least two performance validity tests. Archival CVLT-II data was rescored utilizing the CVLT-3 scoring and normative data. Receiver operator characteristic (ROC) curve analysis was used to evaluate the diagnostic discriminability of the two response bias indices.Both parametric and nonparametric bias indices showed acceptable levels of diagnostic discrimination: AUC = .791 for parametric response bias and AUC = .753 for nonparametric response bias.Parametric response bias' discrimination was statistically superior to the nonparametric responses bias' discrimination. The CVLT-3 response bias score demonstrated good sensitivity and specificity when differentiating between individuals in a clinical sample with TBI and individuals in litigation who demonstrated inadequate performance validity.

OBJECTIVE: To utilize the Rasch model to validate and assess the psychometric properties of the Fatigue Severity Scale (FSS) in patients with epilepsy. METHODS: A total of 307 patients (ageâ¯>â¯18â¯years) with a confirmed diagnosis of epilepsy were consented to participate. Exclusion criteria included patients with psychogenic nonepileptic events, cognitive disabilities, and patients who did not speak/understand English. The nine-step FSS was programmed into software administered to patients on electronic tablets, and patient responses were auto-scored. The Rasch rating scale model (RSM) was used to evaluate the unidimensionality, reliability, and targeting of the FSS. To assess unidimensionality, we examined infit and outfit mean squares. We also assessed unidimensionality of the FSS using a principal component analysis of Rasch residuals, where residuals are understood as the difference between observed and expected data values. We evaluated the internal consistency of person and item performance by examining separation reliability estimates and separation ratio. Differential Item Functioning (DIF) was calculated for gender. RESULTS: There was mixed evidence regarding the extent to which the FSS fit the Rasch model. Outfit values ranged from 0.52 to 2.72 and infit values were 0.60 to 2.18, strongly suggesting the presence of misfitting items: Item 1 ("My motivation is lower when I am fatigued") and Item 2 ("Exercise brings on my fatigue"). SIGNIFICANCE: The nine-item FSS showed fair psychometric properties in this sample of patients with epilepsy. Our study provides unique, supportive information for the use of a modified version of the FSS, omitting the first two items, in patients with epilepsy. Given the prevalence of fatigue and other neuropsychiatric comorbidities of epilepsy, having a validated fatigue scale can aid healthcare providers to identify moderate-to-severe fatigue levels in patients with epilepsy and address the plausible risk factors.

Objective: To evaluate declarative memory outcomes in medically refractory epilepsy patients who underwent either a highly selective laser ablation of the amygdalohippocampal complex or a conventional open temporal lobe resection. Methods: Post-operative change scores were examined for verbal memory outcome in epilepsy patients who underwent stereotactic laser amygdalohippocampotomy (SLAH: n = 40) or open resection procedures (n = 40) using both reliable change index (RCI) scores and a 1-SD change metric. Results: Using RCI scores, patients undergoing open resection (12/40, 30.0%) were more likely to decline on verbal memory than those undergoing SLAH (2/40 [5.0%], p = 0.0064, Fisher's exact test). Patients with language dominant procedures were much more likely to experience a significant verbal memory decline following open resection (9/19 [47.4%]) compared to laser ablation (2/19 [10.5%], p = 0.0293, Fisher's exact test). 1 SD verbal memory decline frequently occurred in the open resection sample of language dominant temporal lobe patients with mesial temporal sclerosis (8/10 [80.0%]), although it rarely occurred in such patients after SLAH (2/14, 14.3%) (p = 0.0027, Fisher's exact test). Memory improvement occurred significantly more frequently following SLAH than after open resection. Interpretation: These findings suggest that while verbal memory function can decline after laser ablation of the amygdalohippocampal complex, it is better preserved when compared to open temporal lobe resection. Our findings also highlight that the dominant hippocampus is not uniquely responsible for verbal memory. While this is at odds with our simple and common heuristic of the hippocampus in memory, it supports the findings of non-human primate studies showing that memory depends on broader medial and lateral TL regions.
RESUMO
Background The relationship between tarsal tunnel syndrome (TTS), electrodiagnostic (Edx) findings, and surgical outcome is unknown. Analysis of TTS surgical release outcome patient satisfaction and comparison to Edx nerve conduction studies (NCSs) is important to improve outcome prediction when deciding who would benefit from TTS release. Methods Retrospective study of 90 patients over 7 years that had tarsal tunnel (TT) release surgery with outcome rating and preoperative tibial NCS. Overall, 64 patients met study inclusion criteria with enough NCS data to be classified into one of the following three groups: (1) probable TTS, (2) peripheral polyneuropathy, or (3) normal. Most patients had preoperative clinical provocative testing including diagnostic tibial nerve injection, tibial Phalen's sign, and/or Tinel's sign and complaints of plantar tibial neuropathic symptoms. Outcome measure was percentage of patient improvement report at surgical follow-up visit. Results Patient-reported improvement was 92% in the probable TTS group ( n = 41) and 77% of the non-TTS group ( n = 23). Multivariate modeling revealed that three out of eight variables predicted improvement from surgical release, NCS consistent with TTS ( p = 0.04), neuropathic symptoms ( p = 0.045), and absent Phalen's test ( p = 0.001). The R 2 was 0.21 which is a robust result for this outcome measurement process. Conclusion The best predictors of improvement in patients with TTS release were found in patients that had preoperative Edx evidence of tibial neuropathy in the TT and tibial nerve plantar symptoms. Determining what factors predict surgical outcome will require prospective evaluation and evaluation of patients with other nonsurgical modalities.
RESUMO
Still considered a new ASD, teratogenicity from lacosamide (LCM) exposure during pregnancy is unknown. LCM metabolism through several cytochrome P450 enzymes and minor glucuronidation metabolism in the liver may increase during pregnancy and theoretically lead to lower LCM levels during pregnancy and the risk of increased seizures. Our objective was to determine the impact of pregnancy on serum LCM levels in a series of women with epilepsy (WWE). We identified seven pregnancies with exposure to LCM with at least one level drawn during pregnancy. Patient ages ranged from 18 to 38â¯years (mean 26.4â¯years) and total daily doses of LCM ranged from 200 to 600â¯mg/day. Two patients had increased dose adjustments in response to breakthrough seizures. Dose normalized concentrations (DNC) showed an overall decrease over time through each trimester (pâ¯=â¯0.002) and significantly lower during trimester 2 and 3 (pâ¯=â¯0.001 and pâ¯=â¯0.004, respectively) compared to pre-pregnancy levels. There were no significant changes in seizure frequency and none of the neonates had teratogenic findings at time of birth. We are the first to report a case series on the changes in LCM levels during pregnancy with significant decreased LCM DNC levels during the second and third trimesters in comparison to pre-pregnancy values.

OBJECTIVE: This retrospective study investigated the success rate of withdrawal of antiepileptic drugs (AEDs) following stereotactic laser amygdalohippocampotomy (SLAH) for mesial temporal lobe epilepsy (MTLE), and identiï¬ed predictors of seizure recurrence. MATERIALS AND METHODS: We retrospectively assessed 65 patients who underwent SLAH for MTLE (59 lesional). Patients' demographics, disease characteristics and post-surgical outcomes were evaluated for their potential to predict seizure recurrence associated with withdrawal of AEDs. RESULTS: The mean period of observation post SLAH was 51 months (range 12-96 months) and the mean period to initial reduction of AEDs was 21 months (range 12-60 months). Reduction of AEDs was attempted in 37 patients (57 %) who were seizure free post SLAH and it was successful in approximately 2/3 of them. From the remainder 1/3 who relapsed, nearly all regained seizure control after reinstitution of their AEDs. The likelihood of relapse after reduction of AEDs was predicted only by pre-operative seizure frequency. At the end of the observation period, approximately 14 % of all SLAH patients were seizure free without AEDs and approximately 54 % remained seizure free on AEDs. Compared with preoperative status, the number of AEDs were reduced in 37 % of patients, unchanged in 51 % of them and increased in 12 % of them. CONCLUSIONS: Successful SLAH for MTLE allows for reduction of AEDs in a significant portion of patients and complete withdrawal of AEDs in a subset of them. Patients with higher pre-operative seizure frequency exhibit a greater chance of relapse post reduction of AEDs.

OBJECTIVE: The aim of the study was to determine what factors determine the quality of rehabilitation clinical practice guidelines. DESIGN: Six databases were searched for articles that had applied the Appraisal of Guidelines for Research & Evaluation II quality assessment tool to rehabilitation clinical practice guidelines. The 573 deduplicated abstracts were independently screened by two authors, resulting in 81 articles, the full texts of which were independently screened by two authors for Appraisal of Guidelines for Research & Evaluation II application to rehabilitation clinical practice guidelines, resulting in a final selection of 40 reviews appraising 504 clinical practice guidelines. Data were extracted from these by one author and checked by a second. Data on each clinical practice guideline included the six Appraisal of Guidelines for Research & Evaluation II domain scores, as well as the two Appraisal of Guidelines for Research & Evaluation II global evaluations. RESULTS: All six Appraisal of Guidelines for Research & Evaluation II domain scores were statistically significant predictors of overall clinical practice guideline quality rating; D3 (rigor of development) was the strongest and D1 (scope and purpose) the weakest (overall model P < 0.001, R2 = 0.53). Five of the six domain scores were significant predictors of the clinical practice guideline use recommendation, with D3 the strongest predictor and D5 (applicability) the weakest (overall model P < 0.001, pseudo R2 = 0.53). CONCLUSIONS: Quality of rehabilitation clinical practice guidelines may be improved by addressing key domains such as rigor of development.

PURPOSE: Ulnar sensory palmar crossover to digit three (D3), the Berrettini anastomosis, is measurable in routine electrodiagnostic nerve conduction studies. The crossover is reported as occurring in 60% of anatomic dissections, but the frequency of measurable ulnar crossover to D3 and its potential as a nerve conduction pitfall is not established. The purpose of this article was to present descriptive statistics regarding the frequency of measurable Berrettini anastomosis in nerve conduction studies. METHODS: A retrospective chart review and data analysis was completed on 248 patients representing 411 extremities with a main outcome measure of ulnar sensory stimulated nerve conduction simultaneous waveform recording on D3 and digit four (D4). Consistent electrodiagnostic technique with waveform recording data analysis in a private practice and independent university waveform verification was completed on sequential patients referred for upper extremity electrodiagnostic testing. RESULTS: Measurable ulnar stimulated D3 sensory nerve action potentials were demonstrated in 34% of patients with amplitudes of 27%, the simultaneously recorded corresponding ulnar D4 amplitudes representing electrophysiological evidence of ulnar sensory crossover. CONCLUSIONS: The Berrettini anastomosis can frequently be seen as a small amplitude sensory nerve action potential response, but at times can be observed with an amplitude greater than 10 µV. It is possible that patients with an absent or significantly delayed median nerve response may have simultaneous inadvertent spread of stimulus to ulnar axons measurable on D3 that may be interpreted as a falsely normal response. All electromyographers need to be aware of this potential pitfall.

OBJECTIVE: To determine whether the 12 items of the Template for Intervention Description and Replication (TIDieR) can be combined into a single summary score reflecting intervention reporting completeness and quality. DESIGN: Systematic review and reanalysis of published data. After a systematic search of the published literature, 16 review articles were retrieved with 489 sets of 12 TIDieR ratings of experimental intervention, comparator, or the 2 combined as reported in primary studies. These 489 sets were recoded into a common format and analyzed using Rasch analysis for binary items. SETTING: Not applicable. PARTICIPANTS: Not applicable. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Psychometric qualities of a Rasch Analysis-based TIDieR summary score. RESULTS: The data fit the Rasch model. Infit and outfit values were generally acceptable (range, 0.70-1.45). TIDieR was reasonably unidimensional in its structure. However, the person (here: study) separation ratio was 1.25 with a corresponding reliability of 0.61. In addition, the confidence interval around each estimate of reporting completeness was wide (model standard error of 0.78). CONCLUSION: Several Rasch indicators suggested that TIDieR is not a strong instrument for assessing the quality of a researcher's reporting on an intervention. It is recommended that it be used with caution. Improvements in TIDieR itself may make it more helpful as a reporting tool.
RESUMO
This study examined the hypothesis that people who receive concussion recovery education would have better outcomes than those who received usual discharge paperwork from the emergency department (ED) and tested whether participants who were in litigation or seeking disability compensation had more symptoms than individuals not engaged in these activities. Two hundred and fifty-five persons with a diagnosis of concussion were assigned randomly to a brief education group (one-page double-sided document), a longer education group (10-page document), and usual care (standard ED discharge instructions), and were these documents in the ED. A (non-concussion) trauma comparison group was enrolled to determine the symptom rate unrelated to brain injury. The Concussion Symptom Checklist (CSC) and litigation and disability status questions were completed by telephone at one week, three months, and six months. Neither long nor brief information handouts had a significant impact on symptoms over time; the standard form had an average decrease of 1.20 symptoms compared with the brief instructional intervention group (p = 0.031). Litigation status and disability seeking status were significant predictors of symptoms on CSC over time: disability seeking (p = 0.017) and litigation status (p = 0.05). Persons seeking Social Security disability or legal compensation endorsed more symptoms over time than those who were not. Number of symptoms on the CSC for the trauma control group was the same as those who sustained concussion. Type of recovery material was not as important as noting that concussion symptoms resolve over time, and that remaining symptoms are not specific to brain injury. Litigation and disability seeking behavior accounted for maintained symptoms, rather than the concussion itself.

PURPOSE/OBJECTIVE: Despite the widespread use of the Cognitive Log, information regarding normative performance is only available in individuals with known brain injury and in healthy college students. The purpose of the current research is to provide information about Cognitive Log performance in a regional group of rehabilitation patients without history of brain injury. Secondarily, non-neurological factors that may predict performance are considered. Research Method/Design: Participants included in this study were 121 consecutive patients admitted to an inpatient rehabilitation hospital spinal cord and orthopedic floor. Based on history, only patients without insult to the brain were included. RESULTS: This study provides normative information for Cognitive Log performance in a nonbrain injured population, showing that these patients score in between those with acquired brain injury and healthy controls. Variables including age, estimated intelligence, and self-reported pain, fatigue, and affective distress accounted for 47.5% of the variance in Cognitive Log scores, although age and estimated intelligence, which accounted for 43.3% of the variance, were the only individually significant contributors to performance. CONCLUSIONS/IMPLICATIONS: This study provides an estimate of normative Cognitive Log performance in a nonbrain injured population. This information is especially useful in that it signifies that both neurological and non-neurological factors contribute to Cognitive Log performance, and this information may shape how clinicians conceptualize scores in patients with and without brain injury. Age and longstanding intellectual abilities should be taken into consideration when interpreting Cognitive Log performances, developing rehabilitation strategies, and determining need for additional testing.

OBJECTIVE: To evaluate the effectiveness of a replicable group treatment program for improving social competence after traumatic brain injury (TBI). DESIGN: Multicenter randomized controlled trial comparing 2 methods of conducting a social competency skills program, an interactive group format versus a classroom lecture. SETTING: Community and veteran rehabilitation centers. PARTICIPANTS: Civilian, military, and veteran adults with TBI and social competence difficulties (N=179), at least 6 months postinjury. INTERVENTIONS: The experimental intervention consisted of 13 weekly group interactive sessions (1.5h) with structured and facilitated group interactions to improve social competence, and the control consisted of 13 traditional classroom sessions using the same curriculum with brief supplemental individual sessions but without structured group interaction. MAIN OUTCOME MEASURES: Profile of Pragmatic Impairment in Communication (PPIC), an objective behavioral rating of social communication impairments after TBI. LaTrobe Communication Questionnaire (LCQ), Goal Attainment Scale (GAS), Satisfaction with Life Scale, Posttraumatic Stress Disorder Checklist-C (PCL) civilian version, Brief Symptom Inventory 18 (BSI-18), Scale of Perceived Social Self-Efficacy (PSSE). RESULTS: Social competence goals (GAS) were achieved and maintained for most participants regardless of treatment method. Significant improvements in the primary outcome (PPIC) and 2 of the secondary outcomes (LCQ and BSI) were seen immediately posttreatment and at 3 months posttreatment in the alternative treatment arm only; however, these improvements were not significantly different between the group interactive structured treatment and alternative treatment arms. Similar trends were observed for PSSE and PCL-C. CONCLUSIONS: Social competence skills improved for persons with TBI in both treatment conditions. The group interactive format was not found to be a superior method of treatment delivery in this study.

OBJECTIVES: Chemical-biological-radio-nuclear (CBRN) gas masks are the standard means for protecting the general population from inhalation of toxic industrial compounds (TICs), for example after industrial accidents or terrorist attacks. However, such gas masks would not protect patients on home mechanical ventilation, as ventilator airflow would bypass the CBRN filter. We therefore evaluated in vivo the safety of adding a standard-issue CBRN filter to the air-outflow port of a home ventilator, as a method for providing TIC protection to such patients. METHODS: Eight adult patients were included in the study. All had been on stable, chronic ventilation via a tracheostomy for at least 3 months before the study. Each patient was ventilated for a period of 1 hour with a standard-issue CBRN filter canister attached to the air-outflow port of their ventilator. Physiological and airflow measurements were made before, during, and after using the filter, and the patients reported their subjective sensation of ventilation continuously during the trial. RESULTS: For all patients, and throughout the entire study, no deterioration in any of the measured physiological parameters and no changes in measured airflow parameters were detected. All patients felt no subjective difference in the sensation of ventilation with the CBRN filter canister in situ, as compared with ventilation without it. This was true even for those patients who were breathing spontaneously and thus activating the ventilator's trigger/sensitivity function. No technical malfunctions of the ventilators occurred after addition of the CBRN filter canister to the air-outflow ports of the ventilators. CONCLUSIONS: A CBRN filter canister can be added to the air-outflow port of chronically ventilated patients, without causing an objective or subjective deterioration in the quality of the patients' mechanical ventilation.

: Previous studies suggest low, fixed-dose regimens of activated prothrombin complex concentrate [factor VIII inhibitor bypassing activity (FEIBA); 500âU for international normalized ratio (INR)â<â5; 1000âU for INRâ>â5] is effective for reversal of warfarin-induced life-threatening bleeds. Little data are available on the use of high-dose, weight-based FEIBA for this indication. The objective of this study was to evaluate effectiveness and safety of high-dose, weight-based FEIBA (50âU/kg) vs. frozen plasma alone in this population. This was a matched case-control, multicenter retrospective study including patients who received high-dose, weight-based FEIBA or frozen plasma alone for warfarin-induced life-threatening bleeds matched (1â:â1) based on age and bleed location. Forty-eight patients were included in the analysis (24 FEIBA, 24 frozen plasma). The primary endpoint was time to INR less than 1.5 after administration of FEIBA or frozen plasma. Secondary endpoints include rates of thromboembolic events and mortality. Median baseline INR was 3.7 (interquartile range 2.7, 7.30) and 2.9 (2.3, 6.61) in the FEIBA and frozen plasma groups, respectively (Pâ=â0.13). Median FEIBA dose was 4530 (3672, 5028)âU. Use of FEIBA resulted in faster time to INR less than 1.5 with a median of 2.5 (1.25, 4.15) vs. 12 (5.6, 28.35)âh; (Pâ<â0.0001). Thromboembolic events occurred in nine (16.7%) patients (FEIBA nâ=â5; plasma nâ=â4); (Pâ=â1.0). Mortality was similar in both groups (FEIBA 33% vs. frozen plasma 15%; Pâ=â0.2). The use of high-dose, weight-based FEIBA resulted in faster time to reversal of warfarin-induced coagulopathy compared with frozen plasma alone and showed a similar safety profile.

OBJECTIVES: To investigate the frequency of and reasons for readmissions to acute care (RTAC) during inpatient rehabilitation (IPR) after non-traumatic spinal cord injury (NT-SCI). To develop a predictive model for RTAC using identified risk factors. DESIGN: Retrospective case-control. SETTING: Academic IPR hospital. PARTICIPANTS: Individuals with NT-SCI admitted to an academic SCI rehabilitation unit from January 2014-December 2015. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Readmissions to acute care services from IPR. RESULTS: Thirty-seven participants (20%) experienced a RTAC for a total of 39 episodes. Thirty-five experienced 1 RTAC, while two had 2. The most common medical reasons for RTAC were infection (27%), neurological (27%), and noninfectious respiratory (16%). Multivariable logistic regression was used to develop a model to predict RTAC. Paraplegia was associated with 3.2 times increase in the odds of RTAC (P = 0.03). For every unit increase in FIM-Motor, there was a 5% reduction in the odds of RTAC (P = 0.03) Body mass index less than 30 decreased odds of RTAC by 61% (P = 0.004). CONCLUSION: RTACs were associated with body mass index greater than 30, decreased FIM-Motor subscore on admission, and paraplegia. Physiatrists caring for the non-traumatic SCI patient need be more circumspect of individuals with these parameters to potentially prevent the problems necessitating acute care transfer.

OBJECTIVES: To identify health beliefs of emergency department (ED) patients with low acuity conditions and how these affect ambulance (AMB) utilization. METHODS: We performed a prospective, observational study on a convenience sample of patients 18years or older, who presented to the ED of an urban, academic hospital with an Emergency Severity Index (ESI) triage level of 4 or 5. Demographics, treatment, and disposition data were obtained along with self-administered surveys. Characteristics of patients with low acuity conditions who presented to the ED by AMB were compared to the patients who came to the ED by private transportation (PT). Data were analyzed with the chi-square test, t-test, and Mann-Whitney test. RESULTS: A total of 197 patients (97 AMB and 100 PT) were enrolled. Compared to PT, AMB patients were more likely to: be insured (82% vs. 56%; p=0.000), have a primary care provider (62% vs. 44%; p=0.048), and lack a regular means of transportation (53% vs. 33%; p=0.005). Three surveys were used the SF-8, Short Test of Functional Health Literacy in Adults [STOFHLA], and Health Belief Model [HBM]. Answers to HBM showed patients perceive that their illness required care within one hour of arrival (38% vs. 21%; p=0.04), have used an ambulance in the past year (76% vs. 33%; p=0.001) and to utilize an ambulance in the future for similar concerns (53% vs. 15%; p=0.000). AMB patients were more likely to call an ambulance for any health concern (p=0.035) and felt that there were enough ambulances for all patients in the city (p=0.01). There were no differences in age, employment, level of income and education, nor hospital admission rate between groups. CONCLUSIONS: Ambulance use in low-acuity ED patients is associated with misperceptions regarding severity of illness and resource allocation as well as limited access to private transportation. Understanding patient perceptions of illness and other barriers to receiving care is imperative for the development of interventions aimed at enabling change in health behaviors such as the elective use of limited resources.

STUDY OBJECTIVE: Quantify the correlation between blood pressure variability (BPV) and markers of illness severity: serum lactate (LAC) or Sequential Organ Failure Assessment (SOFA) scores. METHODS: We performed a secondary analysis of data from a prospective, observational study evaluating fluid resuscitation on adult, septic, ED patients. Vital signs and fluid infusion volumes were recorded every 15min during the 3h following ED arrival. BPV was assessed via average real variability (ARV): the average of the absolute differences between consecutive BP measurements. ARV was calculated for the time periods before and after 3 fluid infusion milestones: 10-, 20-, and 30-mL/kg total body weight (TBW). Spearman's rho correlation coefficient analysis was utilized. A p-value<0.05 was considered statistically significant. RESULTS: Forty patients were included. Mean fluid infusion was 33.7mL/kg TBW (SD 22.1). All patients received fluid infusion≥10mL/kg TBW, 25 patients received fluid infusion>20mL/kg TBW, and 16 patients received fluid infusion>30mL/kg TBW. Mean initial LAC was 4.0mmol/L (SD 3.2). Mean repeat LAC was 3.1mmol/L (SD 3.2), obtained an average of 6.6h (SD 5.3) later. Mean SOFA score was 7.0 (SD 4.4). BPV correlated with both follow-up LAC (r=0.564; p=0.023) and SOFA score (r=0.544; p=0.024) among the cohort that received a fluid infusion>20-mL/kg TBW. CONCLUSION: With the finding of a positive correlation between BPV and markers of illness severity (LAC and SOFA scores), this pilot study introduces BPV analysis as a real-time, non-invasive tool for continuous sepsis monitoring in the ED.

OBJECTIVES: The purpose of this study was to compare health care resource utilization among patients who were given intravenous nitroglycerin for acute heart failure (AHF) in the emergency department (ED) by intermittent bolus, continuous infusion, or a combination of both. METHODS: We retrospectively identified 395 patients that received nitroglycerin therapy in the ED for the treatment of AHF over a 5-year period. Patients that received intermittent bolus (n=124) were compared with continuous infusion therapy (n=182) and combination therapy of bolus and infusion (n=89). The primary outcomes were the frequency of intensive care unit (ICU) admission and hospital length of stay (LOS). RESULTS: On unadjusted analysis, rates of ICU admission were significantly lower in the bolus vs infusion and combination groups (48.4% vs 68.7% vs 83%, respectively; P<.0001) and median LOS (interquartile range) was shorter (3.7 [2.5-6.2 days]) compared with infusion (4.7 [2.9-7.1 days]) and combination (5.0 [2.9-6.7 days]) groups; P=.02. On adjusted regression models, the strong association between bolus nitroglycerin and reduced ICU admission rate remained, and hospital LOS was 1.9 days shorter compared with infusion therapy alone. Use of intubation (bolus [8.9%] vs infusion [8.8%] vs combination [16.9%]; P=.096) and bilevel positive airway pressure (bolus [26.6%] vs infusion [20.3%] vs combination [29.2%]; P=.21) were similar as was the incidence of hypotension, myocardial injury, and worsening renal function. CONCLUSIONS: In ED patients with AHF, intravenous nitroglycerin by intermittent bolus was associated with a lower ICU admission rate and a shorter hospital LOS compared with continuous infusion.

OBJECTIVE: The Reliable Digit Span (RDS) is a well-validated embedded indicator of performance validity. An RDS score of ≤7 is commonly referenced as indicative of invalid performance; however, few studies have examined the classification accuracy of the RDS among individuals suspected for dementia. The current study evaluated performance of the RDS in a clinical sample of 934 non-litigating individuals presenting to an outpatient memory disorders clinic for assessment of dementia. METHOD: The RDS was calculated for each participant in the context of a comprehensive neuropsychological assessment completed as part of routine clinical care. Score distributions were examined to establish the base rate of below criterion performance for RDS cutoffs of ≤7, ≤6, and ≤5. One-way ANOVA was used to compare performance on a cognitive screening measure and informant reports of functional independence of those falling below and above cutoffs. RESULTS: A cutoff score of ≤7 resulted in a high prevalence of below-criterion performance (29.7%), though an RDS of ≤6 was associated with fewer below-criterion scores (12.8%) and prevalence of an RDS of ≤5 was infrequent (4.3%). Those scoring below cutoffs performed worse on cognitive measures compared with those falling above cutoffs. CONCLUSIONS: Using the RDS as a measure of performance validity among individuals presenting with a possibility of dementia increases the risk of misinterpreting genuine cognitive impairment as invalid performance when higher cutoffs are used; lower cutoffs may be useful when interpreted in conjunction with other measures of performance validity.
