RESUMEN
BACKGROUND: Older adults (≥65 years) with diabetes and multiple chronic conditions (MCC) (> 2 chronic conditions) experience reduced function and quality of life, increased health service use, and high mortality. Many community-based self-management interventions have been developed for this group, however the evidence for their effectiveness is limited. This paper presents the protocol for a randomized controlled trial (RCT) comparing the effectiveness and implementation of the Aging, Community and Health Research Unit-Community Partnership Program (ACHRU-CPP) to usual care in older adults with diabetes and MCC and their caregivers. METHODS: We will conduct a cross-jurisdictional, multi-site implementation-effectiveness type II hybrid RCT. Eligibility criteria are: ≥65 years, diabetes diagnosis (Type 1 or 2) and at least one other chronic condition, and enrolled in a primary care or diabetes education program. Participants will be randomly assigned to the intervention (ACHRU-CPP) or control arm (1:1 ratio). The intervention arm consists of home/telephone visits, monthly group wellness sessions, multidisciplinary case conferences, and system navigation support. It will be delivered by registered nurses and registered dietitians/nutritionists from participating primary care or diabetes education programs and program coordinators from community-based organizations. The control arm consists of usual care provided by the primary care setting or diabetes education program. The primary outcome is the change from baseline to 6 months in mental functioning. Secondary outcomes will include, for example, the change from baseline to 6 months in physical functioning, diabetes self-management, depressive symptoms, and cost of use of healthcare services. Analysis of covariance (ANCOVA) models will be used to analyze all outcomes, with intention-to-treat analysis using multiple imputation to address missing data. Descriptive and qualitative data from older adults, caregivers and intervention teams will be used to examine intervention implementation, site-specific adaptations, and scalability potential. DISCUSSION: An interprofessional intervention supporting self-management may be effective in improving health outcomes and client/caregiver experience and reducing service use and costs in this complex population. This pragmatic trial includes a scalability assessment which considers a range of effectiveness and implementation criteria to inform the future scale-up of the ACHRU-CPP.

BACKGROUND: Osteoporosis is one of the most under-diagnosed and under-treated health conditions in Canada. This study questioned whether an invitation to self-refer for osteoporosis risk evaluation would improve the number of patients who were tested for bone mineral density (BMD) at a rural Primary Health Care Center (PHCC). PURPOSE: The purpose of this study is to improve osteoporosis care and decrease bone fracture risk in a population of patients 65 years of age and older. METHODOLOGY: A quasi-experimental research design was used to review screening rates of BMD testing and identified patients in this population who were at low, moderate, and high risk for developing osteoporosis. Screening rates at the PHCC were compared to screening rates at another rural PHCC in the province. CONCLUSION: The self-referral program for BMD testing and a nurse-led intervention resulted in an increased number of people who were BMD tested at the study PHCC compared with the control PHCC, and identified more male patients 65 years of age and older who were at risk for osteoporosis and bone fractures. Recommendations suggest future research in other provincial PHCCs that may encourage self-referral programs for BMD testing and improved osteoporosis care for patients 65 years of age and older.

OBJECTIVES: Screening for organ and tissue donation is an essential skill for emergency physicians. In 2015, 4,631 Canadians were on a waiting list for a transplant, and 262 died while waiting. Canada's donation rates are less than half of comparable countries, so it is essential to explore strategies to improve the referral of donors. Poisoned patients may be one such underutilized source for donation. This study explores physician practices and perceptions regarding the referral of poisoned patients as donors. METHODS: In this cross-sectional unidirectional survey, 1,471 physician members of the Canadian Association of Emergency Physicians were invited to participate. Physicians were presented with 20 scenarios and asked whether they would refer the patient as a potential organ or tissue donor. Results were reported descriptively, and associations between demographics and referral patterns were assessed. RESULTS: Physicians totalling 208 participated in the organ or tissue donation scenarios (14.1%); 75% of scenarios involving poisoning were referred for organ or tissue donation, compared with 92% in a non-poisoning scenario. Poisons associated with lower referrals included sedatives, acetaminophen, chemical exposure, and organophosphates. A total of 175 physicians completed the demographic survey (11.9%). Characteristics associated with increased referrals included previous referral experience, donation training, donation support, >10 years of service, urban practice, emergency medicine certification, and male gender. CONCLUSIONS: Scenarios involving poisoning were referred less often when compared with an ideal scenario. Because poisoning is not a contraindication for referral, this represents a potential source of donors. Targeted training and referral support may help improve donation rates in this demographic.

INTRODUCTION: Critically ill patients commonly present to the ED and require aggressive resuscitation. Patient transfer to an ICU environment in an expedient manner is considered optimal care. However, this patient population may remain in the ED for prolonged periods of time. The goal of this study is to describe the ED length of stay, and the invasive procedures performed in critically ill ED patients. METHODS: This is a retrospective medical record review of all patients who presented to the study center over a 1 year period. Patient demographic data, in addition to the times of ED presentation and ICU admission were recorded. Invasive procedures performed in the pre-hospital, ED and the initial 24 hours of ICU care were also recorded. RESULTS: Overall, 178 patients' required direct admission to an ICU from the ED, with a mortality rate of 21.9%. The median LOS in the ED for critically ill patients requiring ICU admission was 4.9 h (mean 6.5 h, range 1.4-28.2 h). Seventy percent of patients (125,178, 70.2%) required endotracheal intubation with the majority (118/125, 94.4%) being performed in the ED (80/125, 64.0%) or the prehospital setting (38/125, 30.4%). Central venous access was obtained in 56/178 patients (31.5%), with 17.9% (10/56) completed in the ED. Similarly, arterial catheters were inserted in 99/178 patients (55.6%) with 14.1% (14/99) inserted in the ED. CONCLUSION: Critically ill patients are managed in the emergency department for a significant length of time. Although the majority of airway intervention occurs in the prehospital setting and ED, relatively few patients undergo invasive procedures while in the emergency department.

In this study we examined the spatial relationship of GABA-containing and GnRH-containing neurons by immunocytochemistry and in situ hybridization in larval and adult brains of sea lamprey, Petromyzon marinus. In immunocytochemical studies, GABA-containing neurons were detected early in lamprey development, by day 20 post-fertilization. At this time point, one population of GABA-containing neurons was visualized in the hypothalamus and preoptic area, and another population was located in the olfactory bulb of the telencephalon. By day 30 after fertilization, after the GABA neurons were detected, GnRH-containing neurons were visualized in the preoptic area/rostral hypothalamus region, adjacent to the GABA-containing neurons in the wall of the third ventricle. Similarly, in adult lamprey brains distinct populations of both GABA- and GnRH-containing neurons were located in the hypothalamus adjacent to the third ventricle. To further establish a proximate relationship between GABA and GnRH, the mRNA for glutamate decarboxylase (GAD), the enzyme catalyzing GABA synthesis from glutamate, and GnRH were examined by in situ hybridization in the brains of larval lamprey. These studies also showed that GnRH and GAD are produced in cell populations in and around the third ventricle of the hypothalamus. This close spatial relationship of GABA neurons and GnRH neurons provides a basis for a regulatory role of GABA on GnRH neurons in the sea lamprey.
