Clinical diagnosis of psychiatric comorbidities, performance of screening tests and pattern of psychotropic medication use in patients with chronic pancreatitis.

BACKGROUND: Psychiatric comorbidity measured by screening instruments is common in patients with chronic pancreatitis (CP) but whether this accurately reflects clinical diagnosis of psychiatric comorbidity is unknown and the prevalence of psychotropic medication prescription in CP remains largely unexplored. METHODS: Adult patients (≥18 years) with definite CP were enrolled and completed the Hospital Anxiety and Depression Scale (HADS). Demographics, clinical characteristics and medications were retrieved from case report forms and the electronic health record (EHR). Clinical diagnosis of depression or anxiety was determined by presence of ICD-10 code or inclusion in the patient's EHR problem list or treatment plan. Comparisons were made between patients with and without clinical psychiatric comorbidity. RESULTS: Total of 81 patients (48, 59.3% male; mean age 57.6 ± 14.3 years) were included. Clinical diagnoses of anxiety and depression were each noted in 47 (58%) patients, with overlap in 42 (51.9%). Compared to clinical diagnoses, the sensitivity and specificity of a positive screen for anxiety (HADS >7) were 76.6% and 91.2%; for depression 55.3% and 88.2%. Patients with anxiety and/or depression were more frequently female (51.9% v 20.7%), younger (53.6 v 64.9 years), and had alcohol etiology (51.9% v 27.6%) (all p < 0.01). In those with psychiatric comorbidity, 42 (80.8%) were prescribed psychotropic medication, most commonly gabapentinoid (24, 57.1%), selective serotonin reuptake inhibitor (n = 22, 52.4%) or benzodiazepine (n = 20, 47.6%). CONCLUSIONS: Psychiatric comorbidities are common among CP patients and many receive psychotropic medications. Further studies are needed to evaluate the impact of these medications on CP symptoms.

Natural history of spontaneous pancreatic portal vein fistulae: A systematic review of the literature.

BACKGROUND: Spontaneous pancreatic portal vein fistula (PPVF) - a rare complication of pancreatic inflammation - varies widely in presentation and means of diagnosis but has been previously associated with bleeding complications and mortality. A systematic review of published literature was performed to assess the frequency of outcomes. METHODS: A search of electronic databases (PubMed, Ovid MEDLINE, Scopus, EMBASE, gray literature) resulted in 1667 relevant unique manuscripts; 52 met inclusion criteria. RESULTS: A total of 74 unique (male n = 47, 63.5 %) patients were included. Mean age was 53.5 (±11.9) years. History of alcohol use was reported in 55 (74.3 %). Underlying chronic pancreatitis (CP) was present in 49 (66.2 %). In cases where presenting symptoms were reported (n = 57, 77.4 %), the most frequent were abdominal pain (63.5 %), weight loss (14.9 %), rash (12.2 %), nausea/vomiting (12.2 %), and polyarthritis (9.5 %). Computed tomography was the most common imaging modality used to confirm the diagnosis (n = 20, 27.0 %), followed by magnetic resonance cholangiopancreatography (n = 14, 18.9 %). Portal vein thrombosis was reported in 57 (77.0 %), and bleeding events (luminal, variceal, or intra-pseudocyst) were reported in 13(17.6 %) patients. Younger age was associated with higher risk of bleeding events. Mortality was reported in 12 (16.2 %) patients at any time during follow up. Older age and polyarthritis at presentation were associated with mortality. CONCLUSIONS: PPVF is a rare and potentially fatal condition, though rates of bleeding complication and death were relatively low in this population. High-quality observational studies are needed to better understand the pathophysiology and natural history of this diagnosis.

Effects of neurotransmitter receptor antagonists on sea urchin righting behavior and tube foot motility.

Echinoderms, such as sea urchins, occupy an interesting position in animal phylogeny in that they are genetically closer to vertebrates than the vast majority of all other invertebrates but have a nervous system that lacks a brain or brain-like structure. Despite this, very little is known about the neurobiology of the adult sea urchin, and how the nervous system is utilized to produce behavior. Here, we investigated effects on the righting response of antagonists of ionotropic receptors for the neurotransmitters acetylcholine, GABA and glycine, and antagonists of metabotropic receptors for the amines dopamine and noradrenaline (norepinephrine). Antagonists slowed the righting response in a dose-dependent manner, with a rank order of potency of strychnine>haloperidol>propranolol>bicuculline>hexamethonium, with RT50 values (concentrations that slowed righting time by 50%) ranging from 4.3 µmol l-1 for strychnine to 7.8 mmol l-1 for hexamethonium. The results also showed that both glycine and adrenergic receptors are needed for actual tube foot movement, and this may explain the slowed righting seen when these receptors were inhibited. Conversely, inhibition of dopamine receptors slowed the righting response but had no effect on tube foot motility, indicating that these receptors play roles in the neural processing involved in the righting behavior, rather than the actual physical righting. Our results identify the first effects of inhibiting the glycinergic, dopaminergic and adrenergic neurotransmitter systems in adult sea urchins and distinguish between the ability of sea urchins to right themselves and their ability to move their tube feet.

Low rates of cascade genetic testing among families with hereditary gynecologic cancer: An opportunity to improve cancer prevention.

OBJECTIVE: Cascade genetic testing (CGT) of hereditary breast and ovarian cancer (HBOC) or Lynch Syndrome (LS) patients' relatives offers opportunities to prevent cancer, but CGT rates are not well described. We aimed to measure reported disclosure of genetic testing results and CGT rates in these families and evaluate patients' views of educational media. METHODS: Patients with HBOC or LS identified from germline genetic testing at an academic institution between 2011 and 2016 were surveyed regarding disclosure, testing among relatives, and perceptions of educational materials. Medical records and pedigrees provided numbers of total and first-degree relatives. RESULTS: Of 103 mutation carriers consented, 64 (63%) completed the survey an average of 38 months after receiving genetic testing results. Participants' mean age was 53 years, and thirty-one (48%) had a cancer diagnosis. The majority (86%) felt extremely or very comfortable sharing health information. Participants disclosed results to 87% of first-degree relatives, but reported that only 40% of first-degree relatives underwent testing. First-degree female relatives had significantly higher CGT rates than first-degree male relatives (59% versus 21%, P < 0.001). Participants with HBOC reported higher CGT rates than those with LS (49% versus 33%, P = 0.02). Participants did not identify any one educational medium as more helpful than the others for disclosing results. CONCLUSION: Disclosure rates are high among HBOC and LS mutation carriers, but reported CGT rates are low. Gender- and mutation-specific barriers prevent patients' family members from undergoing CGT. Future studies should implement materials to address these barriers and improve CGT rates.

Children's disaster reactions: the influence of family and social factors.

This review examines family (demographics, parent reactions and interactions, and parenting style) and social (remote effects, disaster media coverage, exposure to secondary adversities, and social support) factors that influence children's disaster reactions. Lower family socioeconomic status, high parental stress, poor parental coping, contact with media coverage, and exposure to secondary adversities have been associated with adverse outcomes. Social support may provide protection to children in the post-disaster environment though more research is needed to clarify the effects of certain forms of social support. The interaction of the factors described in this review with culture needs further exploration.

Children's disaster reactions: the influence of exposure and personal characteristics.

This paper reviews children's reactions to disasters and the personal and situational factors that influence their reactions. Posttraumatic stress disorder (PTSD) and posttraumatic stress reactions are the most commonly studied outcomes, though other conditions also occur including anxiety, depression, behavior problems, and substance use. More recently, traumatic grief and posttraumatic growth have been explored. New research has delineated trajectories of children's posttraumatic stress reactions and offered insight into the long-term consequences of their disaster experiences. Risk factors for adverse outcomes include pre-disaster vulnerabilities, perception of threat, and loss and life disruptions post-disaster. Areas in need of additional research include studies on the timing and course of depression and anxiety post-event and their interactions with other disorders, disaster-related functional and cognitive impairment, positive outcomes, and coping.

Association between supratentorial pediatric high-grade gliomas involved with the subventricular zone and decreased survival: a multi-institutional retrospective study.

OBJECTIVE: The subventricular zone (SVZ), housed in the lateral walls of the lateral ventricles, is the largest neurogenic niche in the brain. In adults, high-grade gliomas in contact or involved with the SVZ are associated with decreased survival. Whether this association holds true in the pediatric population remains unexplored. To address this gap in knowledge, the authors conducted this retrospective study in a pediatric population with high-grade gliomas treated at three comprehensive centers in the United States. METHODS: The authors retrospectively identified 63 patients, age ≤ 21 years, with supratentorial WHO grade III-IV gliomas treated at three academic centers. Basic demographic and clinical data regarding presenting signs and symptoms and common treatment variables were obtained. Preoperative MRI studies were evaluated to assess SVZ contact by tumor and to quantify tumor volume. RESULTS: Sixty-three patients, including 34 males (54%), had a median age of 12.3 years (IQR 6.50-16.2) and a median tumor volume of 39.4 ml (IQR 19.4-65.8). Tumors contacting the SVZ (SVZ+) were noted in 34 patients (54%) and overall were larger than those not in contact with the SVZ (SVZ-; 51.1 vs 27.3, p = 0.002). The SVZ+ tumors were also associated with decreased survival. However, age, tumor volume, tumor grade, and treatment with chemotherapy and/or radiation were not associated with survival in the 63 patients. In the univariable analysis, near-total resection, gross-total resection, and seizure presentation were associated with increased survival (HR = 0.23, 95% CI 0.06-0.88, p = 0.03; HR = 0.26, 95% CI 0.09-0.74, p = 0.01; and HR = 0.46, 95% CI 0.22-0.97, p = 0.04, respectively). In a multivariable stepwise Cox regression analysis, only SVZ+ tumors remained significantly associated with decreased survival (HR = 1.94, 95% CI 1.03-3.64, p = 0.04). CONCLUSIONS: High-grade glioma contact with the SVZ neural stem cell niche was associated with a significant decrease in survival in the pediatric population, as it is in the adult population. This result suggests that tumor contact with the SVZ is a general negative prognosticator in high-grade glioma independent of age group and invites biological investigations to understand the SVZ's role in glioma pathobiology.

A Review of Middle School Vocabulary Interventions: Five Research-Based Recommendations for Practice.

Purpose The purpose of this tutorial is to explain key concepts about vocabulary acquisition and instruction and to translate research from middle school vocabulary interventions into practice recommendations for practitioners. In this tutorial, we consider the relationship between vocabulary and reading comprehension, describe vocabulary acquisition including the development of semantic networks, provide a review of high-quality middle school vocabulary studies, and make recommendations for practice. Method We reviewed the experimental and quasi-experimental literature examining the impact of vocabulary instruction on the vocabulary and reading comprehension development of middle school students. We searched multiple electronic databases (e.g., PsycInfo, ERIC, Scopus, Google Scholar) using combinations of specific search terms (i.e., vocabulary, intervention, instruction, middle school, adolescent), searched reviews of vocabulary research, and conducted bibliographic searches of included studies. We then extracted information from each included study about the intervention, participants, and outcomes. Results We identified 17 studies meeting our inclusion criteria. The majority of studies were conducted with students from low socioeconomic status backgrounds. Only 1 study focused exclusively on students with learning disabilities, language impairments, or reading disabilities, highlighting the need for more vocabulary experimental research studies with special populations of students in middle school. Conclusion After reviewing the middle school studies, we make 5 recommendations based on the literature: (a) teach vocabulary intentionally, (b) teach independent word-learning strategies (morphological analysis), (c) focus on developing semantic networks, (d) increase opportunities to use new words in discussion and writing, and (e) provide a motivating and language-rich learning environment.

Resting-state functional magnetic resonance imaging for surgical planning in pediatric patients: a preliminary experience.

OBJECTIVE Cerebral mapping for surgical planning and operative guidance is a challenging task in neurosurgery. Pediatric patients are often poor candidates for many modern mapping techniques because of inability to cooperate due to their immature age, cognitive deficits, or other factors. Resting-state functional MRI (rs-fMRI) is uniquely suited to benefit pediatric patients because it is inherently noninvasive and does not require task performance or significant cooperation. Recent advances in the field have made mapping cerebral networks possible on an individual basis for use in clinical decision making. The authors present their initial experience translating rs-fMRI into clinical practice for surgical planning in pediatric patients. METHODS The authors retrospectively reviewed cases in which the rs-fMRI analysis technique was used prior to craniotomy in pediatric patients undergoing surgery in their institution. Resting-state analysis was performed using a previously trained machine-learning algorithm for identification of resting-state networks on an individual basis. Network maps were uploaded to the clinical imaging and surgical navigation systems. Patient demographic and clinical characteristics, including need for sedation during imaging and use of task-based fMRI, were also recorded. RESULTS Twenty patients underwent rs-fMRI prior to craniotomy between December 2013 and June 2016. Their ages ranged from 1.9 to 18.4 years, and 12 were male. Five of the 20 patients also underwent task-based fMRI and one underwent awake craniotomy. Six patients required sedation to tolerate MRI acquisition, including resting-state sequences. Exemplar cases are presented including anatomical and resting-state functional imaging. CONCLUSIONS Resting-state fMRI is a rapidly advancing field of study allowing for whole brain analysis by a noninvasive modality. It is applicable to a wide range of patients and effective even under general anesthesia. The nature of resting-state analysis precludes any need for task cooperation. These features make rs-fMRI an ideal technology for cerebral mapping in pediatric neurosurgical patients. This review of the use of rs-fMRI mapping in an initial pediatric case series demonstrates the feasibility of utilizing this technique in pediatric neurosurgical patients. The preliminary experience presented here is a first step in translating this technique to a broader clinical practice.

Personalize your management development.

Most organizations struggle with leadership development. They promote tope performers into management roles, put them through a few workshops and seminars, then throw them to the wolves. Managers with the ability to survive and thrive are rewarded; those without it are disciplined or reassigned. The problem is, an alarming number of people fall into the second category. This happens not because managers lack skills but because companies fail to realize that there is no single kind of leader-in-training. In this article, Natalie Shope Griffin, a consultant in executive and organizational development at Nationwide Financial, describes four kinds of manager-in-training, each embodying unique challenges and opportunities. Reluctant leaders appear to have all the necessary skills to be excellent managers but can't imagine themselves succeeding in a leadership role. Arrogant leaders have the opposite problem; they believe they already possess all the management skills they'll ever need. Unknown leaders are overlooked because they don't develop relationships outside of a small circle of close colleagues. Finally, there are the workaholics who put work above all else and spend 100 hours a week in the office. The author outlines specific training approaches tailored to each type of prospective leader. By focusing on the unique circumstances of individual managers, investing in them early in their careers, offering effective coaching, and providing real-life management experiences, Nationwide's leadership-development program has produced hundreds of successful leaders.

A Phase I Clinical Trial of CHT-25 a 131I-Labeled Chimeric Anti-CD25 Antibody Showing Efficacy in Patients with Refractory Lymphoma.

PURPOSE: There is a need for new treatments for Hodgkin and T-cell lymphoma due to the development of drug resistance in a proportion of patients. This phase I study of radioimmunotherapy used CHT-25, a chimeric antibody to the alpha-chain of the interleukin-2 receptor, CD25, conjugated to iodine-131 ((131)I) in patients with refractory CD25-positive lymphomas. EXPERIMENTAL DESIGN: Fifteen patients were treated (Hodgkin lymphoma, 12; angioimmunoblastic T-cell lymphoma, 1; adult T-cell leukemia/lymphoma, 2). Tumor was monitored by computed tomography and in all but two patients by (18)F-fluorodeoxyglucose positron emission tomography. RESULTS: There were no grade 3 or 4 infusion reactions. At the maximum tolerated dose of 1,200 MBq/m(2), the major side effect was delayed myelotoxicity with the nadir for platelets at 38 days and for neutrophils at 53 days. One patient treated with 2,960 MBq/m(2) developed prolonged grade 4 neutropenia and thrombocytopenia and died of Pneumocystis jiroveci pneumonia. Nonhematologic toxicity was mild. Single photon emission computer tomography imaging showed tumor-specific uptake and retention of (131)I and no excessive retention in normal organs. Of nine patients receiving >/=1,200 MBq/m(2), six responded (three complete response and three partial response); one of six patients with administered radioactivity of
