Examining how changes in provincial policy on vape marketing impacted the distribution of vaping advertisements near secondary schools in London,Ontario

ObjectivesOn January 1, 2020, the Government of Ontario passed a regulation banning vaping advertisements by retailers, apart from specialty shops. A motivation for this ban was to limit youth exposure to vaping advertisements. The primary goal of this research was to evaluate the impact of this ban on the number and density of vaping advertisements surrounding secondary schools. Additionally, we examined whether the number of vaping advertisements varied by school socio-demographic characteristics.MethodsThis study used a pre-post design. Audits were conducted December 2019 (pre-ban) and again January to February 2020 (post-ban), to identify vaping advertisements within 800 m surrounding secondary schools (n = 18) in London, Ontario.ResultsPrior to the ban, there were 266 vaping advertisements within 800 m of secondary schools. After the ban, this was reduced to 58, a 78.2% reduction. The mean number of vaping advertisements surrounding schools significantly decreased from 18.1 before the ban to 3.6 after the ban (p < 0.001). A significant positive correlation was found, prior to the ban, between the number of vaping advertisements surrounding schools and school-level residential instability (r = 0.42, p = 0.02). After the ban, no significant correlations were found between the number of vaping advertisements and school socio-demographic characteristics.ConclusionThe provincial ban of vaping advertisements in select retail settings significantly reduced the number of vaping advertisements in the areas surrounding secondary schools in London, Ontario. The ban also reduced socio-demographic inequities in youths’ potential exposure to marketing of vaping products. Continued monitoring of the geographic accessibility and promotion of vaping products is warranted.     

Students conducting consultations in general practice and the acceptability to patients

OBJECTIVES: The General Medical Council has recommended that medical students should gain more experience in general practice. The study set out to determine patients' reactions to consultations conducted by a medical student alone prior to seeing their GP. DESIGN: A random sample of patients attending general practice surgeries in the Oxford area completed a questionnaire following consultation with a medical student. SETTING: Six general practice teaching surgeries. SUBJECTS: Fifth-year medical students. RESULTS: Of 130 responders 98% experienced no disadvantage in seeing the student; 35% considered that there were advantages in seeing the student; 98% said that they would be prepared to consult with a student again; 85% expressed no concerns about the gender of the student. CONCLUSIONS: The results of this study are very reassuring concerning the acceptability to patients of consulting with medical students and are more favourable than those reported for studies of students being present in consultations by GPs.     

Pain syndromes in HIV infection

Pain causes considerable disability and discomfort in HIV (Human Immunodeficiency Virus) infected individuals. A large number of patients infected with HIV suffer from one or more pain-related syndromes. Pain is under-reported and suboptimally managed in these patients. An outline of the different pain syndromes, including headache, oral cavity pain, chest pain, abdominal pain, anorectal pain, musculoskeletal pain and peripheral neuropathic pain, and their aetiologies are discussed. Current pain management modalities, including non-narcotic and narcotic analgesics, tricyclic antidepressants, anticonvulsants, physical therapy and psychological techniques, are outlined. Treatment should be based on the same principles applied to the management of cancer-related pain. A multi-disciplinary, comprehensive approach to pain management will assist these individuals to achieve improved levels of comfort, function and quality of life in this ultimately terminal illness.     

A Correlational Test of the Relationship Between Posttraumatic Growth,Religion, and Cognitive Processing

The present study examined the degree to which event related rumination, a quest orientation to religion, and religious involvement is related to posttraumatic growth. Fifty-four young adults, selected based on prescreening for experience of a traumatic event, completed a measure of event related ruminations, the Quest Scale, an index of religious participation, and the Posttraumatic Growth Inventory. The three subscales of the Quest Scale, the two groups of rumination items (soon after event/within past two weeks), and the index of religious participation were entered in a standard multiple regression with the total score of the Posttraumatic Growth Inventory as the dependent variable. The degree of rumination soon after the event and the degree of openness to religious change were significantly related to Posttraumatic Growth. Congruent with theoretical predictions, more rumination soon after the event, and greater openness to religious change were related to more posttraumatic growth. Present findings offer some confirmation of theoretical predictions, and also offer clear direction for further research on the relationships of religion, rumination, and posttraumatic growth.     

Violence in the Schools: Clinical Issues and Case Analysis for High-Risk Children

School violence in rural communities has gained considerable attention nationally. Examined are theoretical considerations involving escape theory, the risk and protective factors for school violence, case analyses of recent case studies, and discussion of recent school violence involving fatal injuries to others. Also discussed are diagnostic issues in understanding children who are at-risk for school violence and ways school violence maybe managed in the schools. Suggestions and recommendations including recommendations provided by the National School Safety Center for school personnel are offered, as are steps to be taken in creating a safe school environment. This information may be helpful to child psychiatry and clinical personnel who provide services to school aged children.     

Combination antibody therapy with epratuzumab and rituximab in relapsed or refractory non-Hodgkin's lymphoma.

PURPOSE: To explore the safety and therapeutic activity of combination anti-B-cell monoclonal antibody therapy in non-Hodgkin's lymphoma (NHL). PATIENTS AND METHODS: Twenty-three patients with recurrent B-cell lymphoma received anti-CD22 epratuzumab 360 mg/m(2) and anti-CD20 rituximab 375 mg/m(2) monoclonal antibodies weekly for four doses each. Sixteen patients had indolent histologies (15 with follicular lymphoma) and seven had aggressive NHL (all diffuse large B-cell lymphoma [DLBCL]). Indolent patients had received a median of one (range, one to six) prior treatment, with 31% refractory to their last therapy and 81% with high-risk Follicular Lymphoma International Prognostic Index scores. Patients with DLBCL had a median of three (range, one to eight) prior regimens (14% resistant to last treatment) and 71% had high intermediate-risk or high-risk International Prognostic Index scores. All patients were rituximab na?ve. RESULTS: Treatment was well tolerated, with toxicities principally infusion-related and predominantly grade 1 or 2. Ten (67%) patients with follicular NHL achieved an objective response (OR), including nine of 15 (60%) with complete responses (CRs and unconfirmed CRs). Four of six assessable patients (67%) with DLBCL achieved an OR, including three (50%) CRs. Median time to progression for all indolent NHL patients was 17.8 months. CONCLUSION: The full-dose combination of epratuzumab with rituximab was well tolerated and had significant clinical activity in NHL, suggesting that this combination should be tested in comparison with single-agent treatment.     

Neoplastic human embryonic stem cells as a model of radiation resistance of human cancer stem cells

Studies have implicated that a small sub-population of cells within a tumour, termed cancer stem cells (CSCs), have an enhanced capacity for tumour formation in multiple cancers and may be responsible for recurrence of the disease after treatment, including radiation. Although comparisons have been made between CSCs and bulk-tumour, the more important comparison with respect to therapy is between tumour-sustaining CSC versus normal stem cells that maintain the healthy tissue. However, the absence of normal known counterparts for many CSCs has made it difficult to compare the radiation responses of CSCs with the normal stem cells required for post-radiotherapy tissue regeneration and the maintenance of tissue homeostasis. Here we demonstrate that transformed human embryonic stem cells (t-hESCs), showing features of neoplastic progression produce tumours resistant to radiation relative to their normal counterpart upon injection into immune compromised mice. We reveal that t-hESCs have a reduced capacity for radiation induced cell death via apoptosis and exhibit altered cell cycle arrest relative to hESCs in vitro. t-hESCs have an increased expression of BclXL in comparison to their normal counterparts and re-sensitization of t-hESCs to radiation upon addition of BH3-only mimetic ABT737, suggesting that overexpression of BclXL underpins t-hESC radiation insensitivity. Using this novel discovery platform to investigate radiation resistance in human CSCs, our study indicates that chemotherapy targeting Bcl2-family members may prove to be an adjuvant to radiotherapy capable of targeting CSCs.     

Increasing Older Adults’ Use of Positive Reappraisal Coping for Chronic Physical Illness

Positive reappraisal, a cognitive emotion regulation strategy of identifying personally relevant positive meaning following a stressor, has been demonstrated to be particularly relevant for older adults. However, research has not examined whether this strategy can be taught to older adults to facilitate coping. We examined whether we could increase chronically ill older adults’ use of positive reappraisal and whether it was associated with increased positive emotion and reduced distress. Twenty-six community-dwelling older adults with a current medically diagnosed chronic physical illness perceived to be at least moderately stressful were taught to use positive reappraisal. Participants reported increased positive reappraisal use and emotional well-being, indicating that positive reappraisal can be taught to chronically ill older adults to facilitate coping.
