RESUMO

There is growing evidence that seaweed extracts (SWE) may be a solution for mitigating the negative effects of salt stress on crop yield and quality, as they introduce bioactive ingredients able to regulate the expression of growth-inducing and stress-responsive genes. We demonstrate that SWE slightly ameliorated the negative physical growth effects of salt stress, especially in the root anatomy of the salt-sensitive (Clark) variety. The SWE did not stimulate or enhance peroxidase (POD) activity in either the salt-sensitive (Clark) or salt-tolerant variety (Manokin). However, a complete assessment of other antioxidant enzymes (SOD, CAT, APX) involved in the ROS detoxification process is further required.

RESUMO

The primary purpose of this study is to evaluate the role of vanity in its longstanding theoretical association with narcissism. This is particularly germane, as the conceptualization and measurement of narcissism have evolved in recent years. This is observed in the development of spectrum and/or dimensional models of narcissism, concomitant with the conceptual developments of vanity that have emerged since its original inclusion in the Narcissism Personality Inventory. Specifically, our research question evaluated whether vanity remains as traditionally construed, i.e., as a facet of narcissism, or is better conceptualized as a distinct construct separated from the earlier models of narcissism and therefore provide novel implications in understanding personality and social behavior. Based on the traits of pride, empathy, and several social behavior variables, it was hypothesized that a differentiation between narcissism and vanity would be observed. The participants were 441 undergraduate students from a large public midwestern university who participated in a self-report online survey. Correlation and regression analyses were conducted. The results revealed that the characterization of vanity is limited to pride and an absence of empathy and social behavior. Findings reaffirm behavior patterns of grandiose and vulnerable narcissism regarding selflessness, image management, and sensitivity to others. The core motivations of vanity are explicated as based on social comparison theory to assess one's subjective and/or objective value though it is not characterized as a "social" trait or by social behavior, in contrast to how narcissism is characterized. Based on our findings and an improved understanding of the narcissism model, we conclude that vanity is more closely related to the grandiose dimension of narcissism and discuss how the underlying motivations of vanity improve our understanding of grandiose narcissism. We discuss the implications that these findings provide to the developing, modern conceptualizations of narcissism and affirm and expand our understanding of vanity in personality.

RESUMO

OBJECTIVE: Clozapine remains the most effective intervention for treatment resistant schizophrenia; however, its use is prohibited following neutropenias. We review neutrophil biology as applied to clozapine and describe the strategies to initiate clozapine following neutropenia used in a case series of 14 consecutive patients rechallenged in a United Kingdom (UK) high-secure psychiatric hospital. We examine outcomes including the use of seclusion and transfer. METHODS: A case series of 14 male patients with treatment resistant schizophrenia treated with clozapine despite previous episodes of neutropenia between 2006 and 2015 is presented. Data were collected during 2015 and 2019. Using this routinely collected clinical data, we describe the patient characteristics, causes of neutropenia, the strategies used for rechallenging with clozapine and clinical outcomes. RESULTS: Previous neutropenias were the result of benign ethnic neutropenia, clozapine, other medications and autoimmune-related. Our risk mitigation strategies included: granulocyte-colony stimulating factor (G-CSF), lithium and watch-and-wait. There were no serious adverse events; at follow up half of the patient's had improved sufficiently to transfer them to conditions of lesser security. There were dramatic reductions in the use of seclusion. CONCLUSION: Even in this extreme group, clozapine can be safely and effectively re/initiated following neutropenias, resulting in marked benefits for patients. This requires careful planning based on an understanding of neutrophil biology and the aetiology of the specific episode of neutropenia.

RESUMO

Clozapine remains the only drug treatment likely to benefit patients with treatment resistant schizophrenia. Its use is complicated by an increased risk of neutropenia and so there are stringent monitoring requirements and restrictions in those with previous neutropenia from any cause or from clozapine in particular. Despite these difficulties clozapine may yet be used following neutropenia, albeit with caution. Having had involvement with 14 cases of clozapine use in these circumstances we set out our approach to the assessment of risks and benefits, risk mitigation and monitoring with a practical guide.

RESUMO

AIMS AND METHOD: To investigate the percentage of patients who commenced smoking after transferring out of a non-smoking forensic psychiatric unit, the corresponding clozapine dose adjustments, the effects on plasma clozapine/norclozapine concentrations and observed changes in mental state. We reviewed the notes and plasma clozapine/norclozapine concentrations of 46 patients transferred to medium secure units between July 2008 and December 2013. RESULTS: Thirty-five patients commenced smoking. Their median clozapine dose was increased by 50 mg/d. In the non-smokers, the median clozapine dose remained unchanged. Plasma clozapine/norclozapine concentrations were significantly reduced in smokers despite dosage adjustment. Eighteen patients experienced deterioration in mental state after transfer; almost all these patients were smokers. CLINICAL IMPLICATIONS: Approximately three-quarters of patients who were non-smokers by virtue of being in a secure non-smoking environment commenced smoking after transfer. Monitoring of clozapine serum levels and assessment of mental state in the immediate period after a change in smoking status is indicated.

RESUMO

The 13-item Emergency Developmental Assets Profile measures the well-being of children and youth in emergency settings such as refugee camps and armed conflict zones, assessing whether young people are experiencing adequate positive relationships and opportunities, and developing positive values, skills, and self-perceptions, despite being in crisis circumstances. The instrument was found to have acceptable and nearly identical internal consistency reliability in 22 administrations in non-emergency samples in 15 countries (.75), and in 4 samples of youth ages 10-18 (n = 1550) in the emergency settings (war refugees and typhoon victims, .74) that are the measure's focus, and evidence of convergent validity. Confirmatory Factor Analysis showed acceptable model fit among those youth in emergency settings. Measures of model fit showed that the Em-DAP has configural and metric invariance across all emergency contexts and scalar invariance across some. The Em-DAP is a promising brief cross-cultural tool for assessing the developmental quality of life as reported by samples of youth in a current humanitarian crisis situation. The results can help to inform international relief program decisions about services and activities to be provided for children, youth, and families in emergency settings.

RESUMO

OBJECTIVES: Patients prescribed clozapine were surveyed to assess (a) the effects, both positive and adverse, and overall satisfaction with clozapine in comparison to previously prescribed antipsychotics and (b) the relative significance of effects experienced, both positive and adverse, in terms of impact on subjective well-being. METHODS: A total of 56 male patients prescribed clozapine at a forensic psychiatric hospital were surveyed using a 27-item questionnaire. All patients had been prescribed clozapine for a minimum of 3 months. Respondents were asked to rate effects and satisfaction with clozapine treatment in comparison with previously prescribed antipsychotic medication on a five-point scale. Respondents were also asked to rate effects experienced with clozapine treatment in terms of impact on subjective well-being on a five-point scale. RESULTS: A total of 89% of respondents reported greater satisfaction with clozapine than with previously prescribed antipsychotic medication. A majority of patients reported positive effects in terms of an improvement in their quality of life (68%) and social abilities (52%) with clozapine in comparison with previously prescribed antipsychotics. Nocturnal hypersalivation (84%) and weight gain (57%) were the most common adverse effects. Hedonic responses were assessed for each effect in order to determine the associated subjective experiences. The most positive hedonic responses were for quality of life, mood and alertness. In terms of adverse impact on subjective well-being, nocturnal hypersalivation ranked highest. CONCLUSIONS: Patients in a UK forensic sample are largely satisfied with clozapine treatment. The subjective effects of clozapine treatment should be taken into account by clinicians when assessing response. This may provide an opportunity to highlight the positive changes and prioritize management of the most undesirable adverse effects, which is likely to promote compliance and improve longer term treatment outcomes.

RESUMO

Preclinical compounds tested in animal models often show limited efficacy when transitioned into human clinical trials. As a result, many patients are stratified into treatment regimens that have little impact on their disease. In order to create preclinical models that can more accurately predict tumor responses, we established patient-derived xenograft (PDX) models of colorectal cancer (CRC). Surgically resected tumor specimens from colorectal cancer patients were implanted subcutaneously into athymic nude mice. Following successful establishment, fourteen models underwent further evaluation to determine whether these models exhibit heterogeneity, both at the cellular and genetic level. Histological review revealed properties not found in CRC cell lines, most notably in overall architecture (predominantly columnar epithelium with evidence of gland formation) and the presence of mucin-producing cells. Custom CRC gene panels identified somatic driver mutations in each model, and therapeutic efficacy studies in tumor-bearing mice were designed to determine how models with known mutations respond to PI3K, mTOR, or MAPK inhibitors. Interestingly, MAPK pathway inhibition drove tumor responses across most models tested. Noteworthy, the MAPK inhibitor PD0325901 alone did not significantly mediate tumor response in the context of a KRAS(G12D) model, and improved tumor responses resulted when combined with mTOR inhibition. As a result, these genetically diverse models represent a valuable resource for preclinical efficacy and drug discovery studies.

RESUMO

This exploratory study was done first to determine the appropriateness of Barnard's Feeding Scale (BFS) as a measure of dyadic interaction between caregivers and residents with dementia. Seventy-five of the 76 discrete BFS behaviors were observed during the feedings, thus indicating appropriateness of the BFS. Then, 228 dyadic feedings were observed and scored to achieve the second purpose: to numerically describe caregiver-resident interaction during mealtimes in two nursing homes. Results showed caregivers in both nursing homes demonstrated the highest interaction scores on BFS subscale Response to Distress and the lowest scores on two of the caregiver subscales, Sensitivity to Cues and Social-Emotional Responsiveness. Caregivers' total mean scores correlated (r = 0.523) with those of residents. The third purpose of the study was accomplished using quantitative data to begin exploring the potential influence of participant and other factors during feeding. Clinically, the specific behavioral items of the BFS provide objective assessment of caregiver-resident interaction during feeding.
