Acute downregulation of emerin alters actomyosin cytoskeleton connectivity and function.

Fetal lung fibroblasts contribute dynamic infrastructure for the developing lung. These cells undergo dynamic mechanical transitions, including cyclic stretch and spreading, which are integral to lung growth in utero. We investigated the role of the nuclear envelope protein emerin in cellular responses to these dynamic mechanical transitions. In contrast to control cells, which briskly realigned their nuclei, actin cytoskeleton, and extracellular matrices in response to cyclic stretch, fibroblasts that were acutely downregulated for emerin showed incomplete reorientation of both nuclei and actin cytoskeleton. Emerin-downregulated fibroblasts were also aberrantly circular in contrast to the spindle-shaped controls and exhibited an altered pattern of filamentous actin organization that was disconnected from the nucleus. Emerin knockdown was also associated with reduced myosin light chain phosphorylation during cell spreading. Interestingly, emerin-downregulated fibroblasts also demonstrated reduced fibronectin fibrillogenesis and production. These findings indicate that nuclear-cytoskeletal coupling serves a role in the dynamic regulation of cytoskeletal structure and function and may also impact the transmission of traction force to the extracellular matrix microenvironment.

The Utility and Impact of the Painful Periods Screening Tool (PPST) to Improve Healthcare Delivery for People with Symptoms of Pelvic Pain.

The objective of this study was to evaluate the utility and impact of the Painful Periods Screening Tool (PPST) to improve healthcare delivery for people with symptoms of pelvic pain. The design of this study was a survey study. After IRB approval, patients aged 18-55 years with self-reported pelvic, abdominal, or lower back pain before, during, or after menstrual periods were invited to participate in the study from September 2020 to June 2021. Participants filled out the PPST questionnaire on the day of their Johns Hopkins clinic visit and the follow-up questionnaire 1-14 days after the clinic visit. Demographics and duration of pain were assessed, and participants who completed the PPST questionnaire were sent a follow-up questionnaire to assess utility and impact of PPST. Of the 1352 patients who met study eligibility, 1000 participants responded to both questionnaires. Most subjects (82.9%; 95% CI: 80.4-85.2%) reported having severe pelvic/abdominal or lower back pain during menses. Nine hundred fifteen participants (91.5%; 95% CI: 89.6-93.2%) reported that if given regularly, the PPST would help women discuss their pain symptoms with their healthcare provider. Six hundred seventy-eight participants (67.8%; 95% CI: 64.8-70.7%) reported that the PPST helped them initiate a conversation about their symptoms. Seven hundred seven participants (70.7%; 95% CI: 67.8-73.5%) were more comfortable discussing symptoms of pelvic pain with their provider after filling out the PPST. These findings support the utility of PPST as an endometriosis screening tool and suggest that this tool facilitated communication between patients and providers about pain symptoms.

Early Inflammatory Cytokine Expression in Cerebrospinal Fluid of Patients with Spontaneous Intraventricular Hemorrhage.

We investigated cerebrospinal fluid (CSF) expression of inflammatory cytokines and their relationship with spontaneous intracerebral and intraventricular hemorrhage (ICH, IVH) and perihematomal edema (PHE) volumes in patients with acute IVH. Twenty-eight adults with IVH requiring external ventricular drainage for obstructive hydrocephalus had cerebrospinal fluid (CSF) collected for up to 10 days and had levels of interleukin-1α (IL-1α), IL-1ß, IL-6, IL-8, IL-10, tumor necrosis factor-α (TNFα), and C-C motif chemokine ligand CCL2 measured using enzyme-linked immunosorbent assay. Median [IQR] ICH and IVH volumes at baseline (T0) were 19.8 [5.8-48.8] and 14.3 [5.3-38] mL respectively. Mean levels of IL-1ß, IL-6, IL-10, TNF-α, and CCL2 peaked early compared to day 9-10 (p < 0.05) and decreased across subsequent time periods. Levels of IL-1ß, IL-6, IL-8, IL-10, and CCL2 had positive correlations with IVH volume at days 3-8 whereas positive correlations with ICH volume occurred earlier at day 1-2. Significant correlations were found with PHE volume for IL-6, IL-10 and CCL2 at day 1-2 and with relative PHE at days 7-8 or 9-10 for IL-1ß, IL-6, IL-8, and IL-10. Time trends of CSF cytokines support experimental data suggesting association of cerebral inflammatory responses with ICH/IVH severity. Pro-inflammatory markers are potential targets for injury reduction.

CSF and serum inflammatory response and association with outcomes in spontaneous intracerebral hemorrhage with intraventricular extension: an analysis of the CLEAR-III Trial.

BACKGROUND: Intracerebral hemorrhage (ICH) results in a cascade of inflammatory cell activation with recruitment of peripheral leukocytes to the brain parenchyma and surrounding the hematoma. We hypothesized that in patients with ICH and intraventricular hemorrhage (IVH), a robust cerebrospinal fluid (CSF) inflammatory response occurs with leukocyte subtypes being affected by alteplase treatment and contributing to outcomes. METHODS: Serum and CSF cell counts from patients in the phase 3 Clot Lysis: Evaluating Accelerated Resolution of Intraventricular Hemorrhage (CLEAR III) trial were analyzed. CSF leukocytes were corrected for the presence of red blood cells. Trends in cell counts were plotted chronologically. Associations were evaluated between serum and CSF leukocyte subtypes and adjudicated functional outcome (modified Rankin Scale; mRS) at 30 and 180 days and bacterial infection according to treatment with intraventricular alteplase versus saline. RESULTS: A total of 279 and 292 patients had ≥3 differential cell counts from serum and CSF, respectively. CSF leukocyte subtypes evolved during IVH resolution with a significantly augmented inflammatory response for all subtypes in alteplase- compared to saline-treated patients. CSF leukocyte subtypes were not associated with detrimental effect on functional outcomes in the full cohort, but all were associated with poor 30-day outcome in saline-treated patients with IVH volume ≥20 mL. Higher serum lymphocytes were associated with good functional outcomes (mRS 0-3) in the entire cohort and saline-treated but not alteplase-treated group. Conversely, increased serum neutrophil-to-lymphocyte ratio (NLR) in the entire cohort and saline group was associated with worse functional outcomes. Higher median serum lymphocytes were associated with the absence of infection at 7 days. CONCLUSIONS: Aseptic CSF inflammation after IVH involves all leukocyte subtypes. Serum lymphocytes may be associated with better outcomes by mitigating infection. Alteplase augments the inflammatory response without affecting outcomes.

Longitudinal comparisons of a whole-mouth taste test to clinician-rated and patient-reported outcomes of dysgeusia postradiotherapy in patients with head and neck cancer and associations with oral intake.

BACKGROUND: After head and neck cancer (HNC) treatment, dysgeusia may be a barrier to oral intake. In this exploratory study, we prospectively examined taste perception, clinician-rated (CRO) and patient-reported (PRO) taste changes and their effect on oral intake postradiotherapy. METHODS: Twenty-eight patients were assessed at baseline, treatment weeks 2 and 4, and 1, 3, and 6 months post-treatment using a whole-mouth taste test and associated CRO and subjective PRO measures. RESULTS: Greater taste impairment was reflected by subjective than by a whole-mouth taste test. The most significant and consistent decline occurred mid-treatment. The Chemotherapy-Induced Taste Alteration Scale (PRO) discomfort subscale correlated significantly with maintaining an oral diet, percent of oral intake, and appetite level from mid-treatment to 6 months post-treatment. CONCLUSIONS: PRO results indicated ongoing oral intake issues. Whole-mouth taste tests may fail to fully reflect functional taste-loss. Dysgeusia prevention and treatment methods are needed to improve patient outcomes.

Approaches to Measuring Trends in Interdisciplinary Research Publications at One Academic Medical Center.

PURPOSE: To determine if interdisciplinary research has increased between 2005 and 2015, based on an analysis of journal articles containing at least 1 author from Johns Hopkins University, and to compare different methods for determining the disciplinarity of research articles. METHOD: In 2017-2018, 100 peer-reviewed biomedical science articles were randomly selected from years 2005, 2010, and 2015 and classified as unidisciplinary or interdisciplinary based on Scopus author affiliation data (method 1). The corresponding authors of the 2010 and 2015 articles were sent a survey asking them to describe the disciplines involved in their research (method 2) and to define their research as unidisciplinary or interdisciplinary based on provided definitions (method 3). RESULTS: There was a statistically significant increase in the proportion of interdisciplinary articles in 2015 compared with both 2005 and 2010 (P = .02). Comparison of the 3 methods indicated that 45% of the articles were classified as interdisciplinary based on author affiliation data (method 1), 40% based on the corresponding author's description of the disciplines involved in their research (method 2), and 71% based on the corresponding author's definition of their article's disciplinarity (method 3). There was a statistically significant difference in the proportion of articles classified as interdisciplinary between methods 1 and 3 (P < .001) and between methods 2 and 3 (P < .001). CONCLUSIONS: This study found that interdisciplinary research increased at Johns Hopkins University over the past decade and highlights the difference between corresponding authors' views of their own research and other methods for determining interdisciplinarity.

Improvements in Physician Clinical Workflow Measures After Implementation of a Dashboard Program.

PURPOSE: To determine whether a combination of data-driven, personalized feedback and implementation of a graduated, sequential intervention model improved key measures of physician workflow and quality in radiation treatment planning. METHODS AND MATERIALS: All radiation oncologists across 3 facilities at a single academic institution were prospectively evaluated on 5 predefined metrics of timeliness and accuracy in the treatment-planning process using a web-based institutional data repository and an institutional incident learning system. The study period encompassed 10 quarters from 2014 to 2016, with 2013 serving as a retrospective baseline. Physicians received quarterly individualized reports of their compliance metrics (a practice labeled the Physician Dashboard), and administrative interventions were initiated if >20% noncompliance with any metric was exceeded within a quarter. Consecutive quarters of noncompliance resulted in escalating interventions, including progress meetings with department leadership, and culminated in financial penalties. Rates of noncompliance were compared before and after implementation of this model. RESULTS: Three thousand six hundred sixty pre-Dashboard and 9497 post-Dashboard simulations were analyzed. After Dashboard implementation, significant reductions were observed in the rates of simulation orders requiring signature by a covering physician (14.1% vs 7.4%, P < .001), and the submission of plan contours ≥1 day (43.1% vs 23.1%, P < .001) or ≥2 days (30.8% vs 18.3%, P = .002) after the due date. There was some decrease in rates of inaccurate or incomplete plan submissions (6.2% vs 3.9%, P = .08). Seven of the 12 physicians received at least 1 intervention, with only 2 receiving all levels of intervention. CONCLUSIONS: Regular assessment and targeted feedback using the Physician Dashboard significantly improved radiation oncologist compliance with clinically meaningful treatment planning responsibilities at a high-volume academic center.

Intracranial Hypertension and Cerebral Perfusion Pressure Insults in Adult Hypertensive Intraventricular Hemorrhage: Occurrence and Associations With Outcome.

OBJECTIVES: Elevated intracranial pressure and inadequate cerebral perfusion pressure may contribute to poor outcomes in hypertensive intraventricular hemorrhage. We characterized the occurrence of elevated intracranial pressure and low cerebral perfusion pressure in obstructive intraventricular hemorrhage requiring extraventricular drainage. DESIGN: Prospective observational cohort. SETTING: ICUs of 73 academic hospitals. PATIENTS: Four hundred ninety-nine patients enrolled in the CLEAR III trial, a multicenter, randomized study to determine if extraventricular drainage plus intraventricular alteplase improved outcome versus extraventricular drainage plus saline. INTERVENTIONS: Intracranial pressure and cerebral perfusion pressure were recorded every 4 hours, analyzed over a range of thresholds, as single readings or spans (≥ 2) of readings after adjustment for intracerebral hemorrhage severity. Impact on 30- and 180-days modified Rankin Scale scores was assessed, and receiver operating curves were analyzed to identify optimal thresholds. MEASUREMENTS AND MAIN RESULTS: Of 21,954 intracranial pressure readings, median interquartile range 12 mm Hg (8-16), 9.7% were greater than 20 mm Hg and 1.8% were greater than 30 mm Hg. Proportion of intracranial pressure readings from greater than 18 to greater than 30 mm Hg and combined intracranial pressure greater than 20 plus cerebral perfusion pressure less than 70 mm Hg were associated with day-30 mortality and partially mitigated by intraventricular alteplase. Proportion of cerebral perfusion pressure readings from less than 65 to less than 90 mm Hg and intracranial pressure greater than 20 mm Hg in spans were associated with both 30-day mortality and 180-day mortality. Proportion of cerebral perfusion pressure readings from less than 65 to less than 90 mm Hg and combined intracranial pressure greater than 20 plus cerebral perfusion pressure less than 60 mm Hg were associated with poor day-30 modified Rankin Scale, whereas cerebral perfusion pressure less than 65 and less than 75 mm Hg were associated with poor day-180 modified Rankin Scale. CONCLUSIONS: Elevated intracranial pressure and inadequate cerebral perfusion pressure are not infrequent during extraventricular drainage for severe intraventricular hemorrhage, and level and duration predict higher short-term mortality and long-term mortality. Burden of low cerebral perfusion pressure was also associated with poor short- and long-term outcomes and may be more significant than intracranial pressure. Adverse consequences of intracranial pressure-time burden and cerebral perfusion pressure-time burden should be tested prospectively as potential thresholds for therapeutic intervention.

A randomized 500-subject open-label phase 3 clinical trial of minimally invasive surgery plus alteplase in intracerebral hemorrhage evacuation (MISTIE III).

RATIONALE AND HYPOTHESIS: Surgical removal of spontaneous intracerebral hemorrhage may reduce secondary destruction of brain tissue. However, large surgical trials of craniotomy have not demonstrated definitive improvement in clinical outcomes. Minimally invasive surgery may limit surgical tissue injury, and recent evidence supports testing these approaches in large clinical trials. METHODS AND DESIGN: MISTIE III is an investigator-initiated multicenter, randomized, open-label phase 3 study investigating whether minimally invasive clot evacuation with thrombolysis improves functional outcomes at 365 days compared to conservative management. Patients with supratentorial intracerebral hemorrhage clot volume ≥ 30 mL, confirmed by imaging within 24 h ofknown symptom onset,and intact brainstem reflexes were screened with a stability computed tomography scan at least 6 h after diagnostic scan. Patients who met clinical and imaging criteria (no ongoing coagulopathy; no suspicion of aneurysm, arteriovenous malformation, or any other vascular anomaly; and stable hematoma size on consecutive scans) were randomized to either minimally invasive surgery plus thrombolysis or medical therapy. The sample size of 500 was based on findings of a phase 2 study. STUDY OUTCOMES: The primary outcome measure is dichotomized modified Rankin Scale 0-3 vs. 4-6 at 365 days adjusting for severity variables. Clinical secondary outcomes include dichotomized extended Glasgow Outcome Scale and all-cause mortality at 365 days; rate and extent of parenchymal blood clot removal; patient disposition at 365 days; efficacy at 180 days; type and intensity of ICU management; and quality of life measures. Safety was assessed at 30 days and throughout the study.

Third Ventricle Obstruction by Thalamic Intracerebral Hemorrhage Predicts Poor Functional Outcome Among Patients Treated with Alteplase in the CLEAR III Trial.

INTRODUCTION: The Clot Lysis: Evaluating Accelerated Resolution of IVH trial examined whether irrigating the ventricular system with alteplase improved functional outcomes in patients with small intracerebral hemorrhage (ICH) and large intraventricular hemorrhage (IVH). Thalamic ICH location was common and was associated with poor outcome. One possible explanation is thalamic ICH-associated mass effect obstructing the third ventricle. We hypothesized that patients with thalamic ICH obstructing the third ventricle would have worse functional outcomes compared to patients without obstructing lesions. METHODS: ICH obstruction of third ventricle was defined as third ventricle compression on 1 or more axial computed tomography slices visually impeding cerebral spinal fluid flow. If the third ventricle was casted with IVH, it was scored as such. Multivariable logistic regression analyses were used to determine whether obstruction of the third ventricle predicts poor functional outcomes defined as modified Rankin score (mRS) 4-6, higher mRS, and mortality at 180 days. Models were adjusted for thalamic ICH location, ICH volume, IVH volume, age, hydrocephalus, baseline Glasgow coma scale, and percentage of low cerebral perfusion pressures during treatment. RESULTS: Among saline-treated patients, obstruction of the third ventricle by IVH was a significant predictor of higher mRS at 180 days (OR 1.87, CI 1.01-3.47) and mortality at 180 days (OR 2.73, CI 1.27-5.87) while obstruction by ICH was not. In contrast, among alteplase-treated patients, obstruction by ICH was a significant predictor of mRS 4-6 (OR 3.20, CI 1.30-7.88) and higher mRS at 180 days (OR 2.33, CI 1.24-4.35), while obstruction by IVH was not. CONCLUSIONS: Poor outcomes were associated with mass-related obstruction of the third ventricle from thalamic ICH in alteplase-treated patients and from IVH in saline-treated patients. Once the ventricular system is cleared with alteplase, obstruction of cerebral spinal fluid flow from thalamic ICH might become important in functional recovery.

Alcohol Use Patterns and Subsequent Sexual Behaviors Among Women, Men who have Sex with Men and Men who have Sex with Women Engaged in Routine HIV Care in the United States.

Among people with HIV, alcohol use is associated with increased prevalence of sexual transmission behaviors. We examined associations between alcohol use in the prior year and sexual behaviors approximately six months later among 1857 women, 6752 men who have sex with men (MSM) and 2685 men who have sex with women (MSW). Any alcohol use was associated with increased risk of unsafe vaginal sex among women; anal sex and =>2 anal sex partners among MSM; and anal sex, =>2 anal or vaginal sex partners, and unsafe vaginal sex among MSW. In particular, among women >7 alcoholic drinks/week and among MSW =>5 alcoholic drinks/drinking day increased the likelihood of certain subsequent sexual behaviors. For all groups, especially women, the risk of sex under the influence of drugs/alcohol markedly increased with increases in quantity and frequency of alcohol consumption. These different patterns of drinking and sexual behaviors indicate the importance of tailored counseling messages to women, MSM and MSW.

Establishing a Multidisciplinary Head and Neck Clinical Pathway: An Implementation Evaluation and Audit of Dysphagia-Related Services and Outcomes.

Head and neck cancer (HNC) guidelines recommend regular multidisciplinary team (MDT) monitoring and early intervention to optimize dysphagia outcomes; however, many factors affect the ability to achieve these goals. The aims of this study were to explore the barriers/facilitators to establishing and sustaining a MDT HNC care pathway and to examine the dysphagia-related speech-language pathology (SLP) and dietetic components of the pathway. Using the Consolidated Framework for Implementation Research (CFIR), a mixed methods study design was used to evaluate an established MDT HNC pathway. Ten MDT members provided perceptions of facilitators/barriers to implementing and sustaining the pathway. Patients attending the SLP and dietetic components of the pathway who commenced treatment between 2013 and 2014 (n = 63) were audited for attendance, outcome data collected per visit, and swallowing outcomes to 24-month post-treatment. Dysphagia outcomes were compared to a published cohort who had received intensive prophylactic dysphagia management. Multiple CFIR constructs were identified as critical to implementing and sustaining the pathway. Complexity was a barrier. Patient attendance was excellent during treatment, with low rates of non-compliance (< 15%) to 24 months. Collection of clinician/patient outcome tools was good during treatment, but lower post-treatment. Dysphagia outcomes were good and comparable to prior published data. The pathway provided patients with access to regular supportive care and provided staff opportunities to provide early and ongoing dysphagia monitoring and management. However, implementing and sustaining a HNC pathway is complex, requiring significant staff resources, financial investment, and perseverance. Regular audits are necessary to monitor the quality of the pathway.

Patterns of Decline in Naming and Semantic Knowledge in Primary Progressive Aphasia.

BACKGROUND: Individuals with primary progressive aphasia (PPA) and their caregivers want to know what to expect so that they can plan support appropriately. The ability to predict decline in naming and semantic knowledge, and advise individuals with PPA and their caregivers regarding future planning, would be invaluable clinically. AIMS: The aims of this study were to investigate patterns of decline in naming and semantic knowledge in each of the clinical variants of PPA (logopenic variant PPA, lvPPA; nonfluent agrammatic PPA, nfaPPA; and semantic variant PPA, svPPA) and to examine the effects of other variables on rate of decline. We hypothesized that speech-language rehabilitation, higher education, and higher baseline test scores would be associated with slower decline, and older age with faster decline. METHODS AND PROCEDURES: A total of ninety-four participants with PPA underwent language testing, including thirty six participants with lvPPA, thirty-one participants with nfaPPA, and twenty-seven participants with svPPA. All participant groups were similar in age and education. We focused on decline on three tests: the short form of the Boston Naming Test (BNT), the Hopkins Assessment of Naming Actions (HANA), and the short form of the Pyramids and Palm Trees Test (PPTT). OUTCOME AND RESULTS: Across language tests, the most precipitous rates of decline (loss of points per month) occurred in nfaPPA, followed by svPPA, then lvPPA. Female sex, longer symptom duration, higher baseline test score, and speech-language rehabilitation were associated with slower decline. CONCLUSIONS: PPA variants were distinguishable by rapidity of decline, with nfaPPA having the most precipitous decline. As hypothesized, higher baseline test scores and speech-language rehabilitation were associated with slower decline. Surprisingly, age and education were not important prognostically for individuals in this study. Further study of prognostically-relevant variables in PPA is indicated in this population.

The Johns Hopkins Fall Risk Assessment Tool: A Study of Reliability and Validity.

Patient falls and fall-related injury remain a safety concern. The Johns Hopkins Fall Risk Assessment Tool (JHFRAT) was developed to facilitate early detection of risk for anticipated physiologic falls in adult inpatients. Psychometric properties in acute care settings have not yet been fully established; this study sought to fill that gap. Results indicate that the JHFRAT is reliable, with high sensitivity and negative predictive validity. Specificity and positive predictive validity were lower than expected.

Association between self-reported sexually transmitted infection treatment and mental health symptoms in conflict-affected eastern Democratic Republic of the Congo.

Although poor mental health has been associated with sexual risk behavior, few studies have examined the association between mental health and sexually transmitted infections (STIs) in conflict-affected settings. With elevated symptoms of poor mental health in conflict-affected settings, it is important to consider if and how mental health may be a risk factor for STIs in these settings. We used cross-sectional logistic regression to examine the association between symptoms of depression, anxiety, and post-traumatic stress disorder (PTSD) with having been treated for an STI in rural South Kivu, Democratic Republic of the Congo. Among 753 adults, those with elevated self-reported symptoms of depression and anxiety (adjusted OR = 2.73, 95% CI 1.68, 4.44) and PTSD (adjusted OR = 1.89, 95% CI 1.17, 3.06) had higher odds of reporting ever being treated for an STI than those who were not symptomatic. Our findings suggest that future studies are needed to more rigorously examine the relationship between mental health and STIs.

Corrigendum: Dose-Dependent and Lasting Influences of Intranasal Vasopressin on Face Processing in Men.

[This corrects the article on p. 220 in vol. 8, PMID: 29018407.].

Dose-Dependent and Lasting Influences of Intranasal Vasopressin on Face Processing in Men.

Arginine vasopressin (AVP) and related peptides have diverse effects on social behaviors in vertebrates, sometimes promoting affiliative interactions and sometimes aggressive or antisocial responses. The type of influence, in at least some species, depends on social contexts, including the sex of the individuals in the interaction and/or on the levels of peptide within brain circuits that control the behaviors. To determine if AVP promotes different responses to same- and other-sex faces in men, and if those effects are dose dependent, we measured the effects of two doses of AVP on subjective ratings of male and female faces. We also tested if any influences persist beyond the time of drug delivery. When AVP was administered intranasally on an initial test day, 20 IU was associated with decreased social assessments relative to placebo and 40 IU, and some of the effects persisted beyond the initial drug delivery and appeared to generalize to novel faces on subsequent test days. In single men, those influences were most pronounced, but not exclusive, for male faces, whereas in coupled men they were primarily associated with responses to female faces. Similar influences were not observed if AVP was delivered after placebo on a second test day. In a preliminary analysis, the differences in social assessments observed between men who received 20 and 40 IU, which we suggest primarily reflect lowered social assessments induced by the lower dose, appeared most pronounced in subjects who carry what has been identified as a risk allele for the V1a receptor gene. Together, these results suggest that AVP's effects on face processing, and possibly other social responses, differ according to dose, depend on relationship status, and may be more prolonged than previously recognized.

Differentiating between subtypes of primary progressive aphasia and mild cognitive impairment on a modified version of the Frontal Behavioral Inventory.

Behavioral assessment has been investigated in frontotemporal lobar degeneration and Alzheimer's disease, but has not been explored extensively in subtypes of primary progressive aphasia (PPA). We explored the ability of a modified version of the Frontal Behavioral Inventory (FBI-mod) to discriminate between patients with distinct subtypes of PPA and patients with mild cognitive impairment (MCI). We hypothesized that individuals with nonfluent agrammatic PPA (nfaPPA) would have higher negative behavior scores than other groups and that individuals with semantic variant PPA (svPPA) would have higher disinhibition scores than other groups. Family members and/or caregivers of 120 individuals with PPA and MCI (mean age 69.54+8.75 years; 65 (54%) female; education 16.06±2.68 years; disease duration 46.47±34.26 months) completed the FBI-mod [logopenic PPA (lvPPA) n = 40. nfaPPA n = 29, svPPA n = 27, MCI n = 24]. The groups were not significantly different in age, gender, education, or disease duration. There were no significant differences between the groups for negative behaviors (p = 0.72) and disinhibition scores (p = 0.14). When comparing negative and disinhibition scores (in percent), negative scores were significantly higher in all groups (p < 0.001). When comparing subtest items, there was a pairwise difference between lvPPA and svPPA for restlessness (lvPPA < svPPA, p = 0.02, after adjusting for multiple between-group comparisons). There was a significant difference in the proportion of severe neglect between the groups with lvPPA having a lower proportion than the other two variants (p = 0.05), and there was a significant difference in the proportion of severe poor judgment between the groups with lvPPA also having a lower proportion than nfaPPA (p = 0.04). This study reveals the greater negative behavioral disturbance than disinhibition in the PPA and MCI groups of similar age and duration since onset and identifies different profiles for some specific behaviors for the PPA groups. These findings may have clinical and practical implications.
