This research aimed to explore the perspectives of primary and community care providers on the challenges that hinder the delivery and uptake of personalized type 2 diabetes (T2D) care, with a focus on the integration of mental health support and care.

The day-to-day burden and demand of self-managing T2D can negatively impact quality of life and take a toll on mental health and psychological well-being. As a result, there is a need for personalized T2D self-management education and support that integrates mental health care. Despite the need for this personalized care, existing systems remain siloed, hindering access and uptake. In response, innovative, comprehensive, and collaborative models of care have been developed to address fragmentations in care. As individuals living with T2D often receive their care in primary care settings, linking mental health care to existing teams and networks in primary care settings is required. However, there is a need to understand how best to support access, adoption, and engagement with these models in these unique contexts.

A cross-sectional survey was distributed to primary and community providers of an Ontario-based smoking cessation network. Survey data were analyzed descriptively with free text responses thematically reported.

Survey respondents (n = 85) represented a broad mix of health professions across primary and community care settings. Addressing challenges to the delivery and uptake of personalized T2D care requires comprehensive strategies to address patient-, practice-, and system-level challenges. Findings from this survey identify the need to tailor these models of care to individual needs, clearly addressing mental health needs, and building strong partnership as means of enhancing accessibility and sustainability of integrated care delivery in primary care settings.

We conducted a clinical trial to determine if prophylactic anticonvulsants in brain tumour patients (without prior seizures) reduced seizure frequency. We stopped accrual at 100 patients on the basis of the interim analysis.

One hundred newly diagnosed brain tumour patients received anticonvulsants (AC Group) or not (No AC Group) in this prospective randomized unblinded study. Sixty patients had metastatic, and 40 had primary brain tumours. Forty-six (46%) patients were randomized to the AC Group and 54 (54%) to the No AC Group. Median follow-up was 5.44 months (range 0.13 -30.1 months).

Seizures occurred in 26 (26%) patients, eleven in the AC Group and 15 in the No AC Group. Seizure-free survivals were not different; at three months 87% of the AC Group and 90% of the No AC Group were seizure-free (log rank test, p=0.98). Seventy patients died (unrelated to seizures) and survival rates were equivalent in both groups (median survival = 6.8 months versus 5.6 months, respectively; log rank test, p=0.50). We then terminated accrual at 100 patients because seizure and survival rates were much lower than expected; we would need ≥ 900 patients to have a suitably powered study.

These data should be used by individuals contemplating a clinical trial to determine if prophylactic anticonvulsants are effective in subsets of brain tumour patients (e.g. only anaplastic astrocytomas). When taken together with the results of a similar randomized trial, prophylactic anticonvulsants are unlikely to be effective or useful in brain tumour patients who have not had a seizure.

The Family Group Conference (FGC) is an approach to partnership working which brings together service users, their support network and care professionals in a family-led decision making forum. Evidence, though limited, indicates that that FGC can enhance outcomes for service providers and their users. This study aimed to evaluate the impact of the pilot FGC service, delivered to people with dementia and their families, in terms of the experience of care provision by families and care professionals involved in the project.

Focus group interviews were conducted with families and professionals participating in the pilot intervention.

FGC was perceived as having the potential to positively impact service users, their families, service providers and the wider culture of care. However, despite an overall positive evaluation the participants identified a number of challenges related to service implementation. Both the opportunities and challenges identified in this study are discussed in the context of the existing international evidence base.

This study contributes to a better understanding of the applicability of FGC as a strategy to support people with dementia and their families. Although promising in terms of potential outcomes for service users and providers, FGC presents challenges which need to be carefully managed in order to secure maximum benefit to all parties.

The purpose of this study was to determine incidence, survival rate, and prognostic factors as well as the frequency of Collins’ Law Violators (CLVs) in an unselected population of medulloblastoma patients. Collins’ Law dictates that ’cure’ of a child with a tumor occurs after a period that includes the child’s age at diagnosis plus 9 months.

Using the Alberta Cancer Registry a population-based review identified 49 patients with medulloblastoma (19 adults, 30 children) diagnosed from 1975-96. Pathology was reviewed in all cases. All patients had surgical resection, followed by radiotherapy in 47 patients and chemotherapy in 17.

The overall 5-year survival was 50%. There was a trend for the extent of resection to be associated with a longer survival (Long rank test, p< 0.06) but this was not significant. Tumor recurrence occurred a median of 22.4 months (range, 6.4-192.3) after diagnosis and median survival after recurrence was 9.3 months (range, 0.4-64.9). The survival curve did not appear to plateau but was affected by tumor-related deaths in 3 (21.4%) of the 21 long-term survivors diagnosed in childhood. These three patients had recurrences a mean of 11.7 years after diagnosis and are designated as CLVs.

The survival rate in an unselected population of patients with medulloblastoma is poor. Aggressive resection of the tumors prolongs survival. The Collins’ Law Violators were relatively common and we suggest this concept be abandoned in medulloblastoma.

Chemoradiotherapy followed by monthly temozolomide (TMZ) is the standard of care for patients with glioblastoma multiforme (GBM). Case reports have identified GBM patients who experienced transient radiological deterioration after concurrent chemoradiotherapy which stabilized or resolved after additional cycles of adjuvant TMZ, a phenomenon known as radiographic pseudoprogression. Little is known about the natural history of radiographic pseudoprogression.

We retrospectively evaluated the incidence of radiographic pseudoprogression in a population-based cohort of GBM patients and determined its relationship with outcome and MGMT promoter methylation status.

Out of 43 evaluable patients, 25 (58%) exhibited radiographic progression on the first MRI after concurrent treatment. Twenty of these went on to receive adjuvant TMZ, and subsequent investigation demonstrated radiographic pseudoprogression in 10 cases (50%). Median survival (MS) was better in patients with pseudoprogression (MS 14.5 months) compared to those with true radiologic progression (MS 9.1 months, p=0.025). The MS of patients with pseudoprogression was similar to those who stabilized/responded during concurrent treatment (p=0.31). Neither the extent of the initial resection nor dexamethasone dosing was associated with pseudoprogression.

These data suggest that physicians should continue adjuvant TMZ in GBM patients when early MRI scans show evidence of progression following concurrent chemoradiotherapy, as up to 50% of these patients will experience radiologic stability or improvement in subsequent treatment cycles.

Leptomeningeal disease (LMD) is a late complication of malignant glioma, mostly of glioblastoma, that usually responds poorly to treatment and is rapidly fatal. A long surviving case led us to review our experience with LMD in patients with oligodendrogliomas.

A 15-year retrospective chart review was performed. Patients with both oligodendroglial tumors and LMD were identified. A single neuro-pathologist reviewed all histological sections, a single neuro-radiologist reviewed all available images and lp/19q status was assessed.

Seven out of 145 patients with oligodendroglioma were diagnosed with LMD. Six were male. Median age at tumor diagnosis was 41 years (range, 28-50). None had radiographic or pathological evidence of leptomeningeal or subependymal tumor at initial diagnosis. Most patients had pure anaplastic oligodendrogliomas (4/7); 6/7 had 1p/19q co-deletion. The median time to first relapse was 41 months (range, 19-127). The median time to LMD was 76 months (range, 19-151) from initial diagnosis and 28 months (range, 0-36) from first relapse, respectively. Leptomeningeal disease treatments included spinal radiation and intrathecal and systemic chemotherapy. After progression, some patients with LMD remained stable clinically. The median survival from initial diagnosis was 104 months (range, 19-183) and from LMD diagnosis was 32 months (range, 2-43).

Leptomeningeal disease is a complication of oligodendroglioma that may occur preferentially in long surviving patients with 1p/19q co-deletion. Leptomeningeal disease in patients with oligodendrogliomas appears to be relatively indolent which may have implications for their treatment and be related to 1p/19q status.
