Accurately evaluating for a small bowel obstruction using an abdominal radiograph, by a new method: The Bowel-Spine Ratio

INTRODUCTION

A well-established method does not exist to rule out a small bowel obstruction using an abdominal xray series with significant accuracy. The hypothesis of the study is that the ratio of an average small bowel diameter to lumbar spine diameter over 0.5 is most likely a small bowel obstruction.

METHODS

An x-ray abdominal series measurement technique was applied to 41 subjects with a chief complaint of "abdominal pain" as part of a randomized retrospective case review to predict an obstruction v. non obstruction. A total number of 81 abdominal pain subjects with a mean age of 46.7 years were selected with 40 excluded due to normal small bowel gas pattern. The subject's medical information was unknown to the authors when reading their images. The measurement technique involved averaging the largest and smallest small bowel short axis diameters with comparison to the lowest clearly visible lumbar body width. The subjects' medical course as described in the medical chart or subsequent computed tomography scans were used as the referencing standard to determine presence of obstruction vs non-obstruction.

RESULTS

This method, called the Bowel-Spine Ratio (BSR), resulted in a sensitivity of 0.882 (0.622-0.979; 95% CI), specificity of 0.957 (0.760-0.998; 95% CI), accuracy of 94.7% (80.9%-99.1%; 95% CI) and a positive likelihood ratio of 21 for predicting a small bowel obstruction.

CONCLUSION

The abdominal series Bowel-Spine Ratio is a simple yet effective technique to screen for a small bowel obstruction using limited resources and to avoid unnecessary computed tomography scans with the potential to reduce health care costs.

IMPLICATIONS FOR PRACTICE

Clinicians could have increased confidence in utilizing abdominal radiographs to evaluate for small bowel obstruction.

Evaluating changes to home bowel cancer screening kits: an end-user perspective study

PURPOSE

Many people do not participate in mail-out bowel cancer screening programs due to difficulties using the screening kit. The current study investigated the ways the screening kit could be modified to improve usability.

METHODS

1,109 people evaluated 15 different screening kit modifications. Participants reported on how these kit modifications would affect their screening barriers, their future screening intentions, and how much they would recommend that the modification is made to the current screening kit used the program. All responses were given via an online survey conducted between April and December of 2021.

RESULTS

Seventeen percent of previous NBCSP non-participators indicated that a one-sample test would increase their intention to participate. Recommendation ratings demonstrated higher levels of support for modifications that included providing a barcode naming label (M = 9.06, 95% CI [8.81, 9.31]), having a larger diameter opening of the collection tube (M = 8.42, 95% CI [8.10, 8.74]), and highlighting the expiry date on the kit packaging (M = 8.59, 95% CI [8.29, 8.89]). There were lower levels of support for modifications that reduced the size of the packaging the kit is sent in (M = 6.47, 95% CI [6.09, 6.85]), removed branding from kit packaging (M = 5.98, 95% CI [5.57, 6.39]), and removed the information booklet that comes with the screening kit (M = 5.25, 95% CI [4.78, 5.72]).

CONCLUSION

These findings highlight multiple ways in which bowel cancer screening kits can be changed to increase usability for invitees of national bowel cancer screening programs. Findings have implications for all screening programs that use immunochemical-based bowel cancer screening kits.

Shame in the treatment of patients with psychogenic nonepileptic seizures: The elephant in the room

Previous research has established a link between psychogenic nonepileptic seizures (also known as dissociative or functional seizures) and abnormal emotion processing. In a companion article to this multidisciplinary narrative review, we have argued that, in the context of a biopsychosocial understanding of the condition, the emotion of shame is particularly likely to contribute to the aetiology, manifestation, semiology and perpetuation of psychogenic non-epileptic seizures (PNES). Here we demonstrate how unrecognised and unaddressed shame may cause difficulties when clinicians explain the diagnosis, attempt to engage patients in psychological treatment, construct a diagnostic formulation and undertake psychotherapy. Case vignettes are used to bring theoretical considerations to life and to illustrate the complex interactions which may be observed between high shame proneness, chronic and dysregulated shame, stigma and PNES. The particular focus on shame does not mean that recent explanatory models of PNES are obsolete. Rather, we demonstrate how the inclusion of shame helps to embed the emotional, cognitive and behavioural aspects of the Integrative Cognitive Model (ICM) of PNES in a social / interpersonal context. While we describe how a number of different psychotherapeutic approaches can help to address shame-related processes we conclude that specific modalities are less important than the eventual enhancement of emotional literacy and tolerance through a healing relationship with the psychotherapist.

Shame in patients with psychogenic nonepileptic seizure: A narrative review

Psychogenic Nonepileptic Seizures (PNES) have been linked to dysregulated emotions and arousal. However, the question which emotions may be most relevant has received much less attention. In this multidisciplinary narrative review, we argue that the self-conscious emotion of shame is likely to be of particular importance for PNES. We summarize current concepts of the development of shame processing and its relationship with other emotional states. We demonstrate the potential of acute shame to cause a sudden disruption of normal cognitive function and trigger powerful behavioral, cognitive, physiological and secondary emotional responses which closely resemble key components of PNES. These responses may lead to the development of shame avoidance strategies which can become disabling in themselves. We discuss how excessive shame proneness and shame dysregulation are linked to several psychopathologies often associated with PNES (including depression and PTSD) and how they may predispose to, precipitate and perpetuate PNES disorders, not least by interacting with stigma. We consider current knowledge of the neurobiological underpinnings of shame and PNES. We explore how shame could be the link between PNES and a heterogeneous range of possible etiological factors, and how it may link historical aversive experiences with individual PNES events occurring much later and without apparent external trigger. We argue that, in view of the potential direct links between shame and PNES, the well-documented associations of shame with common comorbidities of this seizure disorder and the well-characterized relationship between chronic shame and stigma, there is a compelling case to pay greater attention to shame in relation to PNES. Its role in the treatment of patients with PNES is discussed in a separate, linked review incorporating case vignettes to highlight the complex interactions of different but interlinked shame-related issues in individual patients.

Using evidence-based psychotherapy to tailor treatment for patients with functional neurological disorders

Functional neurological disorder (FND) frequently presents with comorbid psychopathology (e.g., anxiety, depressive, post-traumatic stress disorders (PTSD), somatic symptom and pain syndromes, and dissociative and personality disorders). It can become chronic and lead to unemployment and disability for many patients. Psychosocial factors play an important role in the onset and perpetuation of symptoms. Consequently, psychotherapy is recommended for the treatment of FND in general, and especially for the single symptom-based subtype of functional seizures (FS). Some of the psychotherapy approaches that have been utilized for FND include cognitive-behavioral therapy (CBT), third wave approaches, and psychodynamic psychotherapies as well as group therapeutic and psychoeducational interventions. For patients with FS and PTSD, prolonged exposure therapy, a CBT-based treatment has been implemented. The purpose of this manuscript is to describe and analyze specific elements (e.g., theoretical foundations, tools, targets, definitions of success) of the main psychotherapeutic approaches used in patients with FND. Our premise is that these modalities will overlap considerably in some respects. We will conclude by discussing how discrete differences may render them more suitable for subgroups of patients with FND or for patients at different timepoints of their recovery process.

Scoping health literacy in Latin America

Studies evaluating the influence of health literacy on patient behavior and outcomes suggest a positive relationship between health literacy and health knowledge, health behaviors, and health status. In Latin American countries, studies assessing health literacy are few, regional, and demonstrate considerable variation, with reported rates of adequate health literacy ranging from 5.0% to 73.3%. In this paper, we examine and explore the state of health literacy and efforts to promote it in Latin America. Key challenges to those efforts include socioeconomic inequality, social/geographic isolation, and cultural-, language-, and policy-related barriers, many of which disproportionately affect indigenous populations and others living in rural areas. Greater use of infographics, videos, and mobile apps may enhance health literacy and patient empowerment, especially when language barriers exist. This paper provides strategies and tools for tailored programming, examples of successful health literacy interventions, and policy recommendations to improve health literacy in Latin America, intending to spur additional discussion and action. Centrally organized collaboration across multiple sectors of society, with community involvement, will enhance health literacy and improve health and well-being across Latin America.

Patients with late onset psychogenic non-epileptic seizures (PNES): How do they compare to those with younger onset?

OBJECTIVE

To determine whether patients who experienced their first psychogenic non-epileptic seizure (PNES) at 50 years or older differed from those who developed PNES at a younger age, in terms of demographic, social/clinical as well as psychological measures.

BACKGROUND

The typical age for PNES onset is roughly between 20 and 40 years of age. Only a handful of studies have examined samples with PNES onset at an older age and therefore information about these individuals is limited.

METHODS

This is a retrospective study of 75 consecutive individuals who developed (video EEG-confirmed diagnosis) PNES before age 50 years and 55 consecutive individuals who developed PNES at 50 years or more. Patients were examined on demographics (age, education, working and relationship status), clinical (seizure frequency, trauma type: sexual, multiple trauma, and health-related traumatic experiences), and self-report measures(Coping Inventory for Stressful Situations, Toronto Alexithymia Scale, and the Quality of Life Inventory in Epilepsy-31).

RESULTS

Patients who had experienced sexual trauma were likelier to develop PNES at an earlier age. Those who experienced "health problems pre-PNES onset" were likelier to develop PNES at an older age. On psychological measures, it was noted that after adjusting for the covariate effects, those with elevations in Avoidance (CISS) were likelier to develop PNES at an earlier age. and those with elevations in QOLIE31 cognitive complaints were likelier to be in the older cohort.

CONCLUSIONS

No matter at what age PNES presented, patients reported markedly high rates of exposure to psychological trauma (single and multiple), similarly elevated unemployment rates and low quality of life.  The groups with different age of onset differed in the type of trauma experienced prior to the development of PNES. In addition, the younger onset group demonstrated a significantly higher use of avoidance as a stress-coping strategy.

Diagnostic utility of the Minnesota multiphasic personality inventory-2 in patients diagnosed with psychogenic non-epileptic seizures in the Czech Republic

PURPOSE

The purpose of the present study is to examine the Minnesota Multiphasic Personality Inventory 2 (MMPI-2) scores of individuals diagnosed with psychogenic non-epileptic seizures (PNES) in a tertiary epilepsy center in the Czech Republic.

METHOD

Patients (F:M 130:45; mean age 36.8 years; 12.7 years of education, frequency of seizures 0.37 per day, illness duration 5.75 years) were assessed while inpatients at the Epilepsy Center, Na Homolce Hospital, Prague. Patients underwent video-EEG testing and comprehensive neuropsychological testing and personality assessment which included the MMPI-2.

RESULTS

Elevated (+1.5SD) F and Back F (Fb) validity scales were observed along with elevated clinical scales Hypochondriasis (Hs), Depression (D), Hysteria (Hy), Psychasthenia (Pt), and Schizophrenia (Sc). Scores higher than 1 SD were found in Psychopathic Deviate (Pd), Paranoia (Pa), Hypomania (Ma) andSocial Introversion (Si) scales and on validity scales True Response Inconsistency Scale (TRIN) and Variable Response Inconsistency Scale (VRIN).

CONCLUSION

Patients diagnosed with PNES exhibit numerous elevations on the MMPI-2. Understanding the underlying psychological constructs of the patient with PNES more accurately improves predictive utility (for the presence of PNES) and allows the clinician to offer interventions that are more customized. Minnesota Multiphasic Personality Inventory results may be useful to exclude other possible diagnoses and to further determine the individual's characteristics that may be helpful when tailoring treatment, including psychotherapy.

Stigma and functional neurological disorder: a research agenda targeting the clinical encounter

Stigma against patients with functional neurological disorder (FND) presents obstacles to diagnosis, treatment, and research. The lack of biomarkers and the potential for symptoms to be misunderstood, invalidated, or dismissed can leave patients, families, and healthcare professionals at a loss. Stigma exacerbates suffering and unmet needs of patients and families, and can result in poor clinical management and prolonged, repetitive use of healthcare resources. Our current understanding of stigma in FND comes from surveys documenting frustration experienced by providers and distressing healthcare interactions experienced by patients. However, little is known about the origins of FND stigma, its prevalence across different healthcare contexts, its impact on patient health outcomes, and optimal methods for reduction. In this paper, we set forth a research agenda directed at better understanding the prevalence and context of stigma, clarifying its impact on patients and providers, and promoting best practices for stigma reduction.

Outcome Measures for Functional Neurological Disorder: A Review of the Theoretical Complexities

The development and selection of optimal outcome measures is increasingly recognized as a key component of evidence-based medicine, particularly the need for the development of a standardized set of measures for use in clinical trials. This process is particularly complex for functional neurological disorder (FND) for several reasons. FND can present with a wide range of symptoms that resemble the full spectrum of other neurological disorders. Additional physical (e.g., pain, fatigue) and psychological (e.g., depression, anxiety) symptoms are commonly associated with FND, which also can be highly disabling with implications for prognosis, and warrant concurrent assessment, despite an unclear etiological relationship with FND. Furthermore, several unique clinical aspects of FND make it likely that the usual prioritization of "objective" (or clinician-rated) over "subjective" (or patient-rated) measures might not be appropriate. Self-report measures may be more clinically meaningful in this patient population. Despite being a common and disabling disorder, there has been little research into outcome measures in FND, and to date trials have largely used measures designed for the assessment of other disorders. An international FND Core Outcome Measure group (FND-COM) has been established to develop a consensus battery of outcomes for FND: a "core outcome set." In this perspective article, the authors reviewed the process of outcome measure development and selection before considering the specific features of FND affecting the development of a core outcome set, as well as a research agenda to optimize outcome measurement in this complex neuropsychiatric disorder.

Good emergency management practices: a review of the core principles, with a focus on preparedness

Animal health emergencies can also have serious socio-economic and public health consequences, including impacts on human health, as well as food security and safety. Therefore, policy-makers and advisers should take an active part in the development of emergency management systems. A formally structured animal health emergency management system sets out, in a systematic way, the elements required to achieve the necessary level of preparedness, and provides for planning and implementation of the appropriate actions to be taken in an emergency. Good emergency management practices, as laid down by the Emergency Management Centre for Animal Health (EMC-AH) of the Food and Agriculture Organization of the United Nations, should incorporate all four phases of an animal health event: peacetime (i.e. before the event occurs), alert, emergency and reconstruction. Five actions are implemented before, during and after an animal health event: prepare, prevent, detect, respond and recover. A strategic action plan can be drafted to schedule the activities required to develop the emergency management system and increase a country's level of preparedness, step by step. The EMC-AH aims to support all components of emergency management at the national, regional and international levels along this progressive pathway for emergency preparedness.

Perioperative intravenous contrast administration and the incidence of acute kidney injury after major gastrointestinal surgery: prospective, multicentre cohort study

BACKGROUND

This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery.

METHODS

This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery.

RESULTS

A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498).

CONCLUSION

There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Outcome measurement in functional neurological disorder: a systematic review and recommendations

OBJECTIVES

We aimed to identify existing outcome measures for functional neurological disorder (FND), to inform the development of recommendations and to guide future research on FND outcomes.

METHODS

A systematic review was conducted to identify existing FND-specific outcome measures and the most common measurement domains and measures in previous treatment studies. Searches of Embase, MEDLINE and PsycINFO were conducted between January 1965 and June 2019. The findings were discussed during two international meetings of the FND-Core Outcome Measures group.

RESULTS

Five FND-specific measures were identified-three clinician-rated and two patient-rated-but their measurement properties have not been rigorously evaluated. No single measure was identified for use across the range of FND symptoms in adults. Across randomised controlled trials (k=40) and observational treatment studies (k=40), outcome measures most often assessed core FND symptom change. Other domains measured commonly were additional physical and psychological symptoms, life impact (ie, quality of life, disability and general functioning) and health economics/cost-utility (eg, healthcare resource use and quality-adjusted life years).

CONCLUSIONS

There are few well-validated FND-specific outcome measures. Thus, at present, we recommend that existing outcome measures, known to be reliable, valid and responsive in FND or closely related populations, are used to capture key outcome domains. Increased consistency in outcome measurement will facilitate comparison of treatment effects across FND symptom types and treatment modalities. Future work needs to more rigorously validate outcome measures used in this population.

Report on a psychoeducational intervention for psychogenic non-epileptic seizures in Argentina

PURPOSE

To examine the effects of a three-session psychoeducational intervention on patients diagnosed with psychogenic non-epileptic seizures (PNES) in an Argentinian public hospital. It was hypothesized that patients would experience improvements in their understanding of PNES, illness perception and affective scores, but might not necessarily experience a significant change in post-traumatic and dissociative symptoms and in seizure frequency.

METHODS

This study included 12 patients (10 women, 2 men) who were invited to participate in a psychoeducational group after receiving a V-EEG confirmed diagnosis of PNES. The group consisted of 3 sessions lasting 2 h each. Pre and post measures included Psychoeducational Intervention Questionnaire, State-Trait Anxiety Inventory, Beck Depression Inventory-II, Brief Illness Perception Questionnaire, Posttraumatic Stress Disorder Diagnostic Scale 5, Dissociative Experiences Scale (DES-M).

RESULTS

This psychoeducational intervention produced results that were similar to interventions reported in US and European studies with regard to changes on psychological measures. Moreover, many patients also reported (on the final day of the intervention) a decrease in seizure frequency. All patients reported that participating in the intervention was a positive experience. Also, all but one patient referred that the participation in the group would have a positive impact on their quality of life.

CONCLUSIONS

Psychoeducational interventions appear to have had positive results in Argentinian patients with PNES. This is initial step in the design of empirically based psychoeducational/supportive initiatives for patients in South America.

Clinical characteristics of psychogenic nonepileptic seizures across the lifespan: An international retrospective study

PURPOSE

Previous studies from a few countries have reported semiological differences in younger children compared with adolescents or adults with psychogenic nonepileptic seizures (PNESs). This study tested the hypothesis that semiological, demographic, and historical risk factors vary with different ages of PNES onset in a large cohort from different countries.

METHODS

In this retrospective study, we investigated patients consecutively referred for PNES, who were admitted to epilepsy monitoring units in Iran, Brazil, Venezuela, Canada, Argentina, and USA. Age, gender, age at seizure onset, seizure semiology, and factors predisposing to PNES (abuse, stressors) were documented according to routine diagnostic practices at each center. Participants were grouped according to their age at onset (i.e., childhood, adolescence, or adulthood).

RESULTS

A total of 448 patients were studied. Female predominance was associated with adolescent- (85/122, 70%) and adult-onset (190/270, 70%) but not in childhood-onset PNES (28/56, 50%) (p = 0.011). Event frequency in the month preceding the diagnosis was higher in the childhood- [x¯ = 50, standard deviation (sd) = 82, p = 0.025] versus adolescent- (x¯ = 24, sd = 36) or adult-onset groups (x¯ = 29, sd = 61). Significant between-group differences were observed for generalized body movements (p = 0.0001) and ictal injury (p = 0.027), suggesting more severe ictal presentations in adult-onset PNES compared with younger ages. Adult-onset patients were also more likely to be taking an unnecessary antiepileptic medication (p = 0.010).

CONCLUSION

While PNES may present at any age, there appear to be notable differences across the lifespan with respect to some of the clinical characteristics. Further international and cross-cultural studies may reveal other interesting characteristics of PNES.

Adult-onset psychogenic nonepileptic seizures: A multicenter international study

PURPOSE

The aim of this multicenter international cross-cultural study was to compare clinical variables in a large sample of people with adult-onset psychogenic nonepileptic seizures (PNES).

METHODS

In this retrospective study, we evaluated persons with documented PNES, who were older than 16 years of age at the onset, from four countries (i.e., Iran, Brazil, Venezuela, and Argentina) regarding their age, gender, PNES semiology, and possible predisposing factors.

RESULTS

We included 389 patients (244 from Iran, 66 from Brazil, 51 from Venezuela, and 28 from Argentina). Age at diagnosis was 32 ± 9 years (range: 17-64 years), and age at the onset of seizures was 27 ± 8 years (range: 17-49 years). There was a female predominance in all countries. The demographic characteristics and factors associated with PNES were similar among the countries. However, there were significant semiological differences among the countries.

CONCLUSION

This study corroborates the notion that PNES share more similarities than differences cross-culturally and across international borders. However, the background determined by cultural, ethnic, and religious differences may influence the semiology of PNES. Further cross-cultural studies involving more than two continents may advance our understanding of PNES.

Sex differences in demographic and clinical characteristics of psychogenic nonepileptic seizures: A retrospective multicenter international study

PURPOSE

Sex-related differences have been reported in patients with neurological and psychiatric disorders. It is also plausible to assume that there might be differences between females and males with psychogenic nonepileptic seizures (PNES).

METHODS

In this retrospective study, we investigated patients with PNES, who were admitted to the epilepsy monitoring units at centers in Iran, the USA, Canada, Brazil, Argentina, and Venezuela. Age, sex, age at seizure onset, seizure semiology, factors potentially predisposing to PNES, and video-electroencephalography recording of all patients were registered routinely.

RESULTS

Four hundred and fifty-one patients had PNES-only and were eligible for inclusion; 305 patients (67.6%) were females. We executed a logistic regression analysis, evaluating significant variables in univariate analyses (i.e., age, age at onset, aura, presence of historical sexual or physical abuse, and family dysfunction). The only variables retaining significance were historical sexual abuse (p = 0.005) and presence of aura (p = 0.01); physical abuse was borderline significant (p = 0.05) (all three were more prevalent among females).

CONCLUSION

Similarities between females and males outweigh the differences with regard to the demographic and clinical characteristics of PNES. However, notable differences are that females more often report lifetime adverse experiences (sexual and probably physical abuse) and auras. While social, psychological, and genetic factors may interact with lifetime adverse experiences in the inception of PNES, the link is not yet clear. This is an interesting avenue for future studies.

Long-term outcome in a sample of underprivileged patients with psychogenic nonepileptic seizures (PNES) living in Argentina

OBJECTIVE

The objective of the present study was to perform a long-term follow-up of economically disadvantaged Latin American patients diagnosed as having psychogenic nonepileptic seizures (PNES) and contribute to the field's understanding of outcome in this population.

BACKGROUND

A handful of studies have examined outcome of patients once the diagnosis of PNES has been communicated. However, the vast majority of these have been conducted in the first world countries with samples that were predominantly Caucasian. There is limited knowledge about outcome in economically disadvantaged Latin American patients diagnosed as having PNES.

METHODS

This is a study of 23 patients (20 women, 3 men) with PNES in which demographic data (age, education, nationality, presence of psychological trauma, age of onset) were retrospectively retrieved from medical files. Follow-up was done through a telephonic questionnaire in which investigators collected clinical information (seizure characteristics at follow-up, and treatments employed) and changes in demographic data.

RESULTS

Patients from this Argentinian PNES sample demonstrated having many similar demographic and clinical characteristics to samples from US and European studies. Long-term follow-up revealed, however, decreased seizure frequency and intensity as well as a substantial improvement in occupational status. A majority had engaged in psychotherapy as well as alternative and complementary approaches. A majority had also developed what are suspected to be other functional symptoms.

CONCLUSIONS

Argentinian patients from economically disadvantaged backgrounds, diagnosed as having PNES reported improvements in seizure frequency and occupational status during long-term follow-up. Future studies will need to focus on what (e.g., communication of diagnosis, psychotherapy, alternative treatments) may have contributed to these changes.

Psychological trauma, somatization, dissociation, and psychiatric comorbidities in patients with psychogenic nonepileptic seizures compared with those in patients with intractable partial epilepsy

OBJECTIVE

The objective of this study was to compare patients with intractable epilepsy with patients with psychogenic nonepileptic seizures (PNES) on the presence of psychological traumas, clinical factors, and psychological measures of somatization and dissociation.

BACKGROUND

Several studies have reported a high prevalence of psychological trauma in patients with PNES, while less have examined the prevalence of psychological trauma in patients with epilepsy and compared both groups. Reports have been somewhat divergent with some describing significantly higher prevalence in physical abuse, others, in emotional abuse/neglect, and others, in sexual abuse in patients with PNES compared with those in patients with epilepsy.

METHODS

This is a retrospective study of 96 patients (61 women, 35 men) with intractable epilepsy (2009 to 2017) and 161 patients (107 women, 54 men) with PNES (2008 to 2018). Demographic and clinical (psychological trauma, depression, anxiety, seizure frequency, and number of antiepileptic drugs) data were collected. The Trauma Symptom Inventory II and the Minnesota Multiphasic Personality Inventory 2RF were administered.

RESULTS

Patients with PNES differed significantly from those with intractable epilepsy on sexual trauma (χ² (5df, N = 257) =9.787, p < .002) and "other" trauma (χ² (5df, N = 257) = 17.9076, p < .000). On psychological measures, there was a significant difference on Somatization scores in patients with PNES (M = 59.63, SD = 11.47) and patients with intractable epilepsy (M = 53.98, SD = 11.31); t(173) = 2.8396, p = .0051, but no difference was noted on a measure of Dissociation. Subsequent principal components analysis revealed that the first 3 principal components (sexual, physical, and other trauma) explained 74.19% of the variability, and that one principal component (dissociation, somatization, demoralization) explained 61.57% of the variability. However, after adjusting for the effects of covariates, only the presence of trauma discriminated between epilepsy and PNES.

CONCLUSIONS

Patients with PNES diagnoses differed from those with epilepsy on a Somatization scale but not on Dissociation or Intrusive Experiences and exhibited significantly higher rates of sexual and "other" trauma compared with those with intractable epilepsy. However, subsequent analyses revealed that a history of psychological trauma was the only condition found to discriminate between patients with PNES and those with epilepsy. These findings suggest that during initial workup and diagnosis, when patients report a history of psychological trauma (sexual or otherwise) a psychogenic nonepileptic etiology should be strongly considered in the differential diagnosis.

Quality of life and psychological dysfunction in traumatized and nontraumatized patients with psychogenic nonepileptic seizures (PNES)

OBJECTIVES

Psychogenic nonepileptic seizures (PNES) have the appearance of epileptic seizures, yet show no epileptiform discharges in the brain. The quality of life (QOL) in patients with PNES is reportedly low and trauma eems to be a relevant risk factor. The objective of this study was to examine the difference between measures of (epilepsy-specific) QOL (Quality of Life in Epilepsy Inventory; QOLIE-31p) and psychological dysfunction (trauma symptom inventory; TSI) between patients with diagnosed PNES with self-reported trauma and those without self-reported trauma.

METHODS

Patients whose PNES diagnoses were through video-electroencephalogram (EEG) monitoring at the Northeast Regional Epilepsy Group between 2008 and 2018 were included. Patients who reported to have a history of psychological trauma and those who did not were assigned to separate groups. Scores from the TSI and QOLIE-31p were compared by using multivariate analysis of covariance.

RESULTS

The total sample was comprised of 217 adult patients, 148 of which self-reported as having experienced psychological trauma in the past and 69 who did not report any psychological trauma. Traumatized patients significantly differed in terms of QOL and TSI from nontraumatized patients. Traumatized patients were demonstrated to have lower scores on the subdomain "energy" of the QOLIE-31p and the total QOLIE-31p score compared to the nontraumatized group. Similarly, the traumatized group had significantly higher scores on nearly all TSI subscales with the exception of suicidality, sexual disturbances, and somatization.

CONCLUSION

This study demonstrated significant differences between patients with PNES who have been psychologically traumatized and those who have not. In particular, patients with a history of psychological trauma present greater psychopathology and would possibly benefit from rapid identification and referral to trauma-based therapy. In turn, this may result in a reduction of disease burden, increase QOL, and a reduction in healthcare costs resulting from diagnostic delays and implementation of less targeted treatments.

International health threats and global early warning and response mechanisms

The global community continues to incur the high costs of crisis mitigation and emergency response to outbreaks of emerging infectious diseases, such as those caused by the H5N1 highly pathogenic avian influenza virus, Ebola virus, Nipah virus, Zika virus or the Middle East respiratory syndrome coronavirus. These viruses are particularly dangerous in regions associated with poor development indicators and high vulnerability. The drivers of these disease crises include failures in the way that animal diseases are detected and reported and failures in the way in which disease response is implemented by animal health and public health systems. In addition, the lack of a coordinated response hampers disease control efforts. A comprehensive approach for disease prevention, detection and response, however, requires a coordinated and joint effort among governments, communities, donors and international networks to invest effectively in prevention systems that can identify early signals of the emergence, spillover and spread of animal pathogens at the local level. These signals include trade bans, market closures, civil unrest, heavy rains and droughts associated with climate change, and livestock intensification or changes in consumer behaviour. The global community needs to increase its investment in early warning and detection systems that can provide information that enables action to be taken at the national, regional and global levels in the event of an outbreak of a transboundary animal disease (TAD). Like any preventive measure, an early warning system requires financial resources, but these are insignificant when compared to the losses that are avoided. Building a global early warning and effective response system for outbreaks is value for money, as the benefits far outweigh the costs. The goal of the Food and Agriculture Organization of the United Nations (FAO) is to end hunger and poverty, which is a challenging and complex task. Building global capacity to prepare for and respond to TADs is an important element of the FAO's strategic objective to increase the resilience of livelihoods to threats and crises. Each year, livestock, and the people who rely upon them for their livelihoods, are confronted with animal disease and crises. They can strike suddenly, causing obvious illness and death, or emerge insidiously and become well established before becoming apparent. Animal disease emergencies threaten the production of, and access to, food; consequently, one of the FAO's missions is to help countries to prepare for and respond to animal health disasters.

Strategies for Increasing Participation in Mail-out Colorectal Cancer Screening Programs. A Systematic Review and Meta-Analysis

Background: Population mail-out bowel screening programs are a convenient, cost-effective and sensitive method of detecting colorectal cancer (CRC). Despite increased survival rates associated with early detection of CRC, in many countries 50% or more of eligible individuals do not participate in such programs, resulting in a substantial amount of cancers progressing undetected and wasted public health resources. Aim: The current study aimed to systematically review all of the interventions that have been applied internationally to increase fecal occult blood test (FOBT) kit return, specifically in population mail-out programs, to make recommendations to policy makers and program organizers as to the most effective methods of increasing uptake. Method: Six electronic databases (PubMed, PsycINFO, Scopus, InformIT, CINAHL, and ProQuest Dissertations and Theses) were searched for articles published in English before 10th of March 2018. Studies were included if they reported the results of an intervention designed to increase the return of FOBT kits that had been mailed to individuals' homes. Results: PRISMA systematic review reporting methods were applied and each study was assessed using Cochrane's risk of bias tool. The quality of evidence was assessed using GRADE guidelines. The review identified 53 interventions from 30 published studies. Nine distinct intervention strategy types were identified and pooled risk ratios and confidence intervals were estimated for each intervention type. Four key effective intervention strategies were identified including telephone contact, GP endorsement, simplified test procedures, and advance notification with small to moderate effect sizes. Conclusions: Interventions that combine program-level changes incorporating the issue of advance notification and alternative screening tools with the involvement of primary health professionals through endorsement letters and telephone contact should lead to increases in kit return in mail-out CRC screening programs. Future research should examine the benefit of combining intervention strategies and tailoring to specific populations.

A Type 1 Diabetes Genetic Risk Score Predicts Progression of Islet Autoimmunity and Development of Type 1 Diabetes in Individuals at Risk

OBJECTIVE

We tested the ability of a type 1 diabetes (T1D) genetic risk score (GRS) to predict progression of islet autoimmunity and T1D in at-risk individuals.

RESEARCH DESIGN AND METHODS

We studied the 1,244 TrialNet Pathway to Prevention study participants (T1D patients' relatives without diabetes and with one or more positive autoantibodies) who were genotyped with Illumina ImmunoChip (median [range] age at initial autoantibody determination 11.1 years [1.2-51.8], 48% male, 80.5% non-Hispanic white, median follow-up 5.4 years). Of 291 participants with a single positive autoantibody at screening, 157 converted to multiple autoantibody positivity and 55 developed diabetes. Of 953 participants with multiple positive autoantibodies at screening, 419 developed diabetes. We calculated the T1D GRS from 30 T1D-associated single nucleotide polymorphisms. We used multivariable Cox regression models, time-dependent receiver operating characteristic curves, and area under the curve (AUC) measures to evaluate prognostic utility of T1D GRS, age, sex, Diabetes Prevention Trial-Type 1 (DPT-1) Risk Score, positive autoantibody number or type, HLA DR3/DR4-DQ8 status, and race/ethnicity. We used recursive partitioning analyses to identify cut points in continuous variables.

RESULTS

Higher T1D GRS significantly increased the rate of progression to T1D adjusting for DPT-1 Risk Score, age, number of positive autoantibodies, sex, and ethnicity (hazard ratio [HR] 1.29 for a 0.05 increase, 95% CI 1.06-1.6; P = 0.011). Progression to T1D was best predicted by a combined model with GRS, number of positive autoantibodies, DPT-1 Risk Score, and age (7-year time-integrated AUC = 0.79, 5-year AUC = 0.73). Higher GRS was significantly associated with increased progression rate from single to multiple positive autoantibodies after adjusting for age, autoantibody type, ethnicity, and sex (HR 2.27 for GRS >0.295, 95% CI 1.47-3.51; P = 0.0002).

CONCLUSIONS

The T1D GRS independently predicts progression to T1D and improves prediction along T1D stages in autoantibody-positive relatives.

Linking animal diseases and social instability

Social instability occurs as a consequence of war, civil strife or natural disasters such as earthquakes, floods and droughts. Animal diseases, including zoonoses, can be both a precursor to social instability and a result of social instability. Coping mechanisms, such as sound policies, trust in government, and robust infrastructure break down at times of civil instability. Such breakdowns often lead to a decline in both public health and the food and agricultural livestock base, thus creating a vicious cycle that involves inadequate nutrition, threatened livelihoods, and fewer opportunities for safe trade. This article is principally a discussion of a theoretical nature on the dynamics between animal diseases and social instability. Based on their experience of working for the Food and Agriculture Organization of the United Nations (FAO), the authors provide numerous examples of the connection between the two, mostly in countries that have fragile environments and are experiencing protracted crises. Disease has a direct and immediate effect on a community, but, in addition, if the community is not able to recover from the impact of a disease on their health and livelihoods, the consequences of an outbreak can persist even after the disease is no longer present. Stability, therefore, depends on a variety of factors, including the ability of a community to overcome the effects of a disease outbreak or other destabilising event. The FAO approach to helping families and communities to cope with the destabilizing effects of animal diseases is to build resilience, particularly amongst the most vulnerable households. This requires individuals and governments to gain a better understanding of what drives disease at the interface between human and animal health. In addition, it requires governments to invest in social protection programmes, establish a long-term risk reduction strategy that decreases vulnerability, and improve the sustainability of safe agricultural and marketing practices.

Health related quality of life of people with non-epileptic seizures: The role of socio-demographic characteristics and stigma

PURPOSE

People with non-epileptic seizures (NES) consistently report poorer Health-Related Quality of Life (HRQoL) than people with epilepsy. Yet, unlike in epilepsy, knowledge of how social factors influence the HRQoL of adults with NES is limited. To add to the evidence base, this study explores the relationship between HRQoL and perceived stigma among adults with NES, and the role of socio-demographic characteristics.

METHODS

Data was gathered from a survey of 115 people living with the condition, recruited from online support groups. Participants provided socio-demographic and health-related data and completed a series of questions investigating their HRQoL (QOLIE-31) and stigma perceptions (10-item Epilepsy Stigma Scale).

RESULTS

Participants were found to experience high levels of perceived stigma (median 5.2, mean 4.9). A significant and moderate inverse correlation was observed between HRQoL and stigma (r_s - 0.474, p = < 0.001); suggesting higher perceptions of stigma contribute to poorer HRQoL among adults with NES. Stigma perceptions were found to be most strongly associated with the seizure worry (r_s = - 0.479), emotional wellbeing (r_s = - 0.421), and social functioning (r_s = 0.407) HRQoL domains. Participants who reported being in employment or education were found to have significantly better HRQoL than those who were not (p = < 0.001).

CONCLUSION

More (qualitative and quantitative) research is justified to understand how - and why - those with the condition experience stigmatisation, and the factors that impede and help facilitate the participation of people with NES in education and employment.

Are there gender differences in those diagnosed with psychogenic nonepileptic seizures?

OBJECTIVE

The objective of the study was to determine whether male and female populations of patients with psychogenic nonepileptic seizures (PNES) differ, in terms of demographic, social/clinical, and etiological factors as well as psychological measures.

BACKGROUND

Psychogenic nonepileptic seizures are overrepresented by females; therefore, information about PNES in males is limited. Only a handful of studies have examined PNES and gender, and of those, one was a literature review and with the exception of two, most have had small sample sizes. Of the existing literature, differences in abuse type, psychiatric diagnoses, and psychometric results have been observed in the two genders.

METHODS

This is a retrospective study of 51 consecutive males and 97 consecutive females with video-electroencephalogram (video-EEG) confirmed diagnosis of PNES. Patients were examined on demographics (age, education, working status), clinical (seizure frequency, trauma type: sexual, nonsexual, age of first trauma), and psychometric measures. The latter included the State Trait Anger Expression Inventory-2 (STAXI-2), Trauma Symptom Inventory-2 (TSI-2), the Coping Inventory for Stressful Situations (CISS), and the Quality of Life Inventory in Epilepsy-31 (QOLIE-31).

RESULTS

Women reported experiencing significantly more sexual traumas (p=0.007) than men. Women also endorsed significantly higher levels of dissociation (p=0.012) and sexual disturbances (p=0.46). In contrast, men reported significantly greater use of avoidance (p=0.001) as a stress coping strategy and higher levels of depression (p=0.006).

CONCLUSIONS

Gender differences were identified with males reporting a significantly higher use of avoidance (cognitive and behavioral avoidance of stress) and depressive symptoms. Women exhibited significantly higher rates of sexual trauma compared with male counterparts. Consequently, women also had significantly higher rates of trauma symptomatology (dissociation and sexual disturbances) which are often observed in those who have been traumatized sexually. These gender distinctions may support different first-line treatment approaches (e.g., trauma-focused; more traditional cognitive behavioral therapy) depending on the most prominent symptomatology.

Prolonged Exposure Therapy for Comorbid Psychogenic Nonepileptic Seizures and Posttraumatic Stress Disorder

Psychogenic nonepileptic seizures (PNES) superficially resemble epileptic seizures but are not associated with epileptic discharges in the brain. Instead, these episodes, which tend to occur with alterations in consciousness and body movements, are thought to be the result of mechanisms of conversion and dissociation. Psychological trauma and PTSD are very prevalent among patients with PNES. PNES can be conceived of as an extreme avoidance mechanism that serves the function of modulating distress and, in some cases, eliminating the precipitant stressor. Avoidance is also an essential component of PTSD. In patients who carry a dual diagnosis of PNES and PTSD, it is sensible that an empirically validated treatment for PTSD such as prolonged exposure (PE) therapy which targets avoidance by promoting exposure might be a useful approach to treat these patients. In this report, we present the case of a 52-year-old male with a 7-year history of PNES. His seizures, which were characterized by intense body shaking and loud guttural outbursts, were occurring up to 15 times per day. Because of these symptoms, he lost his employment and was ostracized by his family. Upon completion of a course of intensive outpatient PE, he achieved full remission of all psychogenic symptoms. Except for three brief seizures, he has maintained his health for 2 years. This constitutes the first detailed report of PE therapy used to effectively treat comorbid PNES and posttraumatic stress symptoms.

Socialization characteristics in persons with epilepsy

OBJECTIVE

The purpose of this report was to describe social behaviors and preferences in adults with epilepsy, including self-reported use of various socialization media (face-to-face and indirect communication) as well as perceived social barriers.

METHODS

1320 consecutive persons with epilepsy (PWEs) confirmed through inpatient video-EEG monitoring were administered a questionnaire on the day of their first appointment. The questionnaire was designed to assess preferences in socialization practices, frequency of interpersonal contact, use of social media, and perceived barriers to socialization. The survey was developed to gain a better understanding of the socialization behaviors and preferences of our patients for the future development of customized activities in our wellness program.

RESULTS

Our sample revealed higher rates of unemployment and single status as compared to the US Census of 2012. With regard socialization however, many were quite social (86% reported daily/weekly communication with friends and family via telephone, 71% saw relatives in person weekly, 68% saw friends weekly, and 65% reported using the computer daily/weekly to socialize). Facebook® was the preferred on-line social media. Indoor/solitary activities were most common with 63% stating they watch TV/read/use the computer followed by physical exercise and spending time outdoors (36%). The frequency of socialization with friends, relatives, and coworkers decreased with the respondents' age and the longer the respondent had carried the diagnosis of epilepsy. Respondents who were taking a greater number of AEDs or were considered refractory were less likely to consider participating in socialization-enhancing activities. The primary barriers to socialization that respondents endorsed were driving prohibition and medication side-effects. Respondents expressed the greatest interest in online support groups or educational programs (31%), office-based support groups (25%), and volunteering (19%).

CONCLUSION

Although the respondents indicate that they do face barriers to socialization, a majority report frequent communication with relatives and friends via phone, in-person and social media. When designing wellness interventions with this group of patients in the future, online, as well as face to face options for support appear to be desired by a number of PWEs.

The effects of lacosamide on cognition, quality-of-life measures, and quality of life in patients with refractory partial epilepsy

OBJECTIVE

The objective of this study was to examine cognitive and quality-of-life measures/quality of life outcomes with adjunctive lacosamide therapy in patients with treatment-resistant partial epilepsy.

METHODS

This was a prospective, open-label, nonblinded, adjunctive therapy test-retest (within subjects) study of patients with treatment-resistant partial epilepsy in which outcome (cognitive functioning and mood/quality of life) was measured in the same subject before and after adjunctive lacosamide administration for 24weeks. The cognitive assessment included the following: Controlled Oral Word Association Test, Buschke Selective Reminding Test, Brief Visuospatial Memory Test-Revised, Stroop Color Word Test, Symbol Digit Modalities Test, Digit Span, Digit Cancellation, and Trails A and B. The quality-of-life measures/quality-of-life assessment included the following: Beck Depression Inventory-II, Profile of Mood States, and Quality of Life Inventory-89. Lacosamide was started at 100mg (50mg twice daily) and could be titrated as needed up to 400mg/day (200mg twice daily). Baseline concomitant AEDs were kept constant. Composite scores were calculated for a pre-post difference score for the cognitive and mood/quality-of-life measures separately and used in regression analyses to correct for the effects of age, education, seizure frequency, seizure severity, dose of lacosamide, and number of AEDs at baseline.

RESULTS

Thirty-four patients were enrolled (13 males, 21 females). Mean age was 38.8±2.43years. Mean seizure frequency decreased significantly from 2.0±2.55 seizures per week at baseline to 1.02±1.72 seizures per week at posttreatment (t=4.59, p<.0001) with a 50% responder rate seen in 18 patients (52.9%). No significant differences were found on the composite scores of the cognitive or the mood/quality-of-life measures after 6months of lacosamide.

SIGNIFICANCE

Lacosamide appeared to have low risks of significant changes in cognition or mood/quality of life. In addition, the present study supports prior studies that have proven lacosamide as an effective adjunctive therapy for the treatment of resistant partial epilepsy.

Interleukin-17 promotes prostate cancer via MMP7-induced epithelial-to-mesenchymal transition

Chronic inflammation has been associated with a variety of human cancers including prostate cancer. Interleukin-17 (IL-17) is a critical pro-inflammatory cytokine, which has been demonstrated to promote development of prostate cancer, colon cancer, skin cancer, breast cancer, lung cancer, and pancreas cancer. IL-17 promotes prostate adenocarcinoma with a concurrent increase of matrix metalloproteinase 7 (MMP7) expression in mouse prostate. Whether MMP7 mediates IL-17’s action and the underlying mechanisms remain unknown. We generated Mmp7 and Pten double knockout (Mmp7^−/− in abbreviation) mouse model and demonstrated that MMP7 promotes prostate adenocarcinoma through induction of epithelial-to-mesenchymal transition (EMT) in Pten-null mice. MMP7 disrupted E-cadherin/β-catenin complex to up-regulate EMT transcription factors in mouse prostate tumors. IL-17 receptor C and Pten double knockout mice recapitulated the weak EMT characteristics observed in Mmp7^−/− mice. IL-17 induced MMP7 and EMT in human prostate cancer LNCaP, C4-2B, and PC-3 cell lines, while siRNA knockdown of MMP7 inhibited IL-17-induced EMT. Compound III, a selective MMP7 inhibitor, decreased development of invasive prostate cancer in Pten single knockout mice. In human normal prostates and prostate tumors, IL-17 mRNA levels were positively correlated with MMP7 mRNA levels. These findings demonstrate that MMP7 mediates IL-17’s function in promoting prostate carcinogenesis through induction of EMT, indicating IL-17-MMP7-EMT axis as potential targets for developing new strategies in the prevention and treatment of prostate cancer.

Psychogenic non-epileptic seizures (PNES) on the Internet: Online representation of the disorder and frequency of search terms

PURPOSE

The nature of the symptoms associated with PNES require a multidisciplinary health team. There are too few professionals with an adequate understanding of PNES and therefore many are not able to provide patients with necessary information. In the age of the internet, it is not surprising that patients or caregivers might look for answers online. The purpose of this project was to investigate the online representation of PNES and search frequency for PNES and its associated terms.

METHODS

To determine online representation, searches of: Google®, twitter®, YouTube®, and Instagram® for "PNES" and associated terms were conducted. Websites, tweets, and films were classified by host and exclusivity of information. PNES and associated terms search frequency was determined through Google Trends®.

RESULTS

Professional and patient sites exclusively about PNES were outnumbered by sites that only mentioned PNES in fewer than three posts. Patients tended to favor less traditional hosting options than did professionals. On twitter®, different keyword preferences were identified for professionals and patients. On YouTube® there was a substantial selection of videos of which 22 were professionally produced. Google Trends®, revealed the terms most commonly used to search for this topic were in order: (1) "PNES;" (2) "NEAD;" and (3) "pseudoseizure."

CONCLUSION

A variety of professional and patient internet content about PNES can be found online. Professional sites offered accurate and empirically-validated information on the disorder and tended to use traditional hosting options. Future professional initiatives might consider novel hosting options and higher-frequency terms to reach their audience more effectively.

Socialization characteristics in patients with psychogenic nonepileptic seizures (PNES)

OBJECTIVE

The purpose of this study was to describe social behaviors and preferences in adults with psychogenic nonepileptic seizures (PNES) including self-reported use of various socialization mediums (face-to-face and indirect communication) as well as perceived social barriers.

METHODS

One hundred forty-one consecutive patients with a diagnosis of PNES that was later confirmed through inpatient video-EEG monitoring were administered a questionnaire on the day of their first outpatient appointment. The questionnaire was designed to assess preferences in socialization practices, frequency of interpersonal contact, use of social media, and perceived barriers to socialization. The survey was developed to gain a better understanding of the socialization behaviors and preferences of our patients for the future development of customized activities in our wellness program.

RESULTS

Contrary to prevalent assumptions that patients with PNES tend to be socially isolated, our responders reported that they were in fact quite socially connected (72.2% reported daily communication with friends and family via telephone, 68.54% saw relatives in person weekly, 65.28% saw friends weekly, and 51.2% reported using the computer daily to socialize). Facebook was the preferred online social media. Indoor/solitary activities were most common with 57.44% stating that they watch TV/read/use the computer. The primary barriers to socialization that respondents endorsed were driving prohibition and medication side effects. Respondents expressed the greatest interest in online support groups or educational programs (29.46%), office-based support groups (28.57%), and volunteering (23.21%).

CONCLUSION

Although it has been speculated that social isolation is a significant problem for patients with PNES, considerable participation in social activities was reported. Characteristics of socialization practices may be more nuanced than first believed. When addressing therapeutic interventions with this group of patients in the future, it might be beneficial to offer both distance-based options as well as face-to-face options for treatment and support depending on age and personal preference.

Depression and quality of life in Spanish-speaking immigrant persons with epilepsy compared with those in English-speaking US-born persons with epilepsy

OBJECTIVE

This study aimed to examine levels of depression and quality of life in Spanish-speaking (less acculturated) immigrants with epilepsy compared with those in English-speaking US-born persons with epilepsy (PWEs).

METHODS

The study included 85 PWEs - 38 Spanish-speaking immigrants with epilepsy and 47 US-born PWEs. All patients underwent video-EEG monitoring and completed depression and quality-of-life inventories in their dominant language (Spanish/English). Chart review of clinical epilepsy variables was conducted by an epileptologist.

RESULTS

Our study revealed that depression scores were significantly higher in Hispanic PWEs (21.65±14.6) than in US-born PWEs (14.50±10.2) (t (64.02)=-2.3, two-sided p=.025). Marital status, medical insurance, antidepressant use, seizure frequency, and number of antiepileptic drugs (AEDs) were tested as covariates in the ANCOVA framework and were not statistically significant at the 0.05 significance level. Fewer Hispanics were prescribed antidepressant medications (13.15% for Hispanics and 40.42% for US-born, χ(2) (1,85) 7.71, p=.005) and had access to comprehensive health insurance coverage (χ(2) (1,85)=13.70, p=0.000). Hispanic patients were also found to be receiving significantly less AEDs compared with their US-born peers (t (83, 85)=2.33, p=.02). Although quality of life was diminished in both groups, Seizure Worry was worse for Hispanics after accounting for potential effects of marital status, medical insurance, use of antidepressants, seizure frequency, and number of antiepileptic drugs (AEDs) ((1, 83), F=7.607, p=0.007).

SIGNIFICANCE

The present study is the first of its kind to examine depression and quality of life in Spanish-speaking US immigrants with epilepsy. Spanish-speaking immigrants with epilepsy have been identified as a group at risk. They demonstrated higher depression scores and more Seizure Worry independent of epilepsy and demographic characteristics compared with their US-born peers. The Hispanic group was receiving less treatment for depression, was taking less AEDs, and had less access to comprehensive health coverage compared with non-Hispanics.

Serum and bal beta-D-glucan for the diagnosis of Pneumocystis pneumonia in HIV positive patients

BACKGROUND/PURPOSE

The diagnosis of patients with pulmonary infiltrates and human immunodeficiency virus (HIV) infection remains a challenge. In current clinical practice the gold standard for Pneumocystis jirovecii pneumonia (PCP) diagnosis remains the identification of the organism in bronco alveolar lavage (BAL) using microscopy (e.g., silver stain). (1->3)-β -d-glucan (BG) is a polysaccharide that is present within the cell wall of Pneumocystis and other fungi.

METHODS

We analyzed serum and BAL lavage fluid from a cohort of 119 patients that did have HIV, a diagnosis of pneumonia and underwent bronchoscopy (FOB) for diagnosis of PCP.

RESULTS

The discriminative power of serum BG for the diagnosis of PCP in this group of patients was very high. Using a cutoff of 300 pg/mL, the sensitivity, specificity, positive predictive value(PPV) and negative predictive value (NPV) were 91%, 92%, 89% and 93% respectively. A model for ROC with just serum BG (N = 108) had an AUC of 0.95. Serum procalcitonin (PCT) and BAL BG were not as accurate for the diagnosis of PCP. For BAL BG using a cutoff of 783 pg/mL, the sensitivity,specificity, positive predictive value (PPV) and negative predictive value (NPV) were 72%, 79%,72% and 79% respectively. The differences between the medians for serum PCT between the group with a without PCP did not reach statistical significance (p = 0.6137).

CONCLUSION

The measurement of serum BG should be incorporated in the diagnostic work up of HIV positive patients with dyspnea and infiltrates on chest X X-ray. Our study confirms the diagnostic value of serum BG previously reported by others but we add a cutoff value that we believe is more accurate for patients with AIDS and suspicion of PCP.

Cognitive differences between patients who have psychogenic nonepileptic seizures (PNESs) and posttraumatic stress disorder (PTSD) and patients who have PNESs without PTSD

OBJECTIVES

The objective of this study was to examine cognitive and clinical differences among three groups of patients diagnosed with psychogenic nonepileptic seizures (PNESs): those with posttraumatic stress disorder (PTSD), those with a history of trauma but no PTSD, and those without a history of trauma.

METHODS

Seventeen patients who were confirmed to have PTSD based on the Trauma Symptom Inventory-2 (TSI-2) and clinical interview were compared with 29 patients without PTSD who had experienced trauma and 17 patients who denied experiencing trauma. We analyzed demographic data, psychiatric information, trauma characteristics, and neuropsychological variables in these groups.

RESULTS

Our study revealed that patients with PNESs with comorbid PTSD performed significantly worse on episodic verbal memory (narrative memory); had greater self-reported Total, Verbal, and Visual Memory impairments; and had higher substance abuse history and use of psychopharmacological agents compared with patients without PTSD regardless of a history of trauma.

CONCLUSION

The present study showed that patients with PNESs diagnosed with PTSD exhibited memory functions that were significantly different from those in patients with PNESs who do not carry a diagnosis of PTSD (regardless of history of trauma). Furthermore, these specific cognitive findings in narrative memory are consistent with those reported in patients with PTSD alone. The present findings contribute to further identifying discrete intragroup differences within PNESs. Identifying a specific psychopathological subgroup such as PTSD will allow clinicians to accurately select treatment.
