Dashboards to Support Implementation of the Quebec Alzheimer Plan: Evaluation Study With Regional and Professional Considerations.

BACKGROUND: Health organizations face the critical task of executing and overseeing comprehensive health care. To address the challenges associated with this task, evidence-based dashboards have emerged as valuable tools. Since 2016, the regional health organizations of Quebec, Canada, have been responsible for ensuring implementation of the Quebec Alzheimer Plan (QAP), a provincial plan that aims to reinforce the capacity of primary care services to detect, diagnose, and treat persons with dementia. Despite the provincial scope of the QAP, the diverse material and human resources across regions introduce variability in the interest, utility, and specific needs associated with these dashboards. OBJECTIVE: The aim of this study was to assess the interest and utility of dashboards to support the QAP implementation, as well as to determine the needs for improving these aspects according to the perspectives of various types of professionals involved across regions. METHODS: An evaluative study using qualitative methods was conducted within a collaborative research approach involving different stakeholders, including the ministerial advisor and the four project managers responsible for supporting the implementation of the QAP, as well as researchers/scientific advisors. To support these organizations, we developed tailored, 2-page paper dashboards, detailing quantitative data on the prevalence of dementia, the use of health services by persons with dementia, and achievements and challenges of the QAP implementation in each organization's jurisdiction. We then conducted 23 focus groups with the managers and leading clinicians involved in the implementation of the QAP of each regional health organization. Real-time notes were taken using a structured observation grid. Content analysis was conducted according to different regions (organizations with university mandates or nearby organizations, labeled "university/peripheral"; organizations for which only part of the territory is in rural areas, labeled "mixed"; and organizations in remote or isolated areas, labeled "remote/isolated") and according to different types of participants (managers, leading clinicians, and other participants). RESULTS: Participants from organizations in all regions expressed interest in these dashboards and found them useful in several ways. However, they highlighted the need for indicators on orphan patients and other health care providers. Differences between regions were observed, particularly in the interest in continuity of care in university/peripheral regions and the need for diagnostic tools adapted to the culture in remote/isolated regions. CONCLUSIONS: These dashboards support the implementation of an Alzheimer Plan and contribute to the emergence of a learning health care system culture. This project allows each region to increase its monitoring capacity for the implementation of the QAP and facilitates reflection among individuals locally carrying out the implementation. The perspectives expressed will guide the preparation of the next iteration of the dashboards.

A fast and reliable larval sampling method for improving the monitoring of fruit flies in soft and stone fruits.

The spotted-wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), threatens both the soft-skinned and stone fruit industry in Asia, Europe, and America. Integrated pest management requires monitoring for infestation rates in real time. Although baited traps for adult D. suzukii are widely used for field monitoring, trap captures are weakly correlated to larval infestation rates. Thus, monitoring for larvae instead of adult flies represents the most reliable monitoring technique. Current methods for larval monitoring (e.g., sugar or salt floatation) are time-consuming and labor-intensive. In this study, we develop a new "sleeve method" for detecting larvae in strawberries through the inspection of individual fruits crushed within transparent plastic sleeves. Samples can be optionally frozen until further processing. Based on count data from non-expert observers, the estimation of larval infestation with the sleeve method is fast, precise, and highly repeatable within and among observers. Mean processing time is half the time compared to previous methods (33-80 s per sample depending on infestation levels). As the accuracy of the sleeve method decreases with infestation levels, we suggest ways to improve its accuracy by incubating fruits for 48 h and calibrating data using fruits with a known number of larvae. The method could also be used in other fruits, as it is easier to use, faster, and requires less equipment than previous monitoring methods. Finally, the method represents a promising tool for growers or researchers to effectively monitor and manage D. suzukii and other insect pests of soft and stone fruits.

The Impact of Green Space on Violent Crime in Urban Environments: An Evidence Synthesis.

Can the presence of green space in urban environments reduce the frequency of violent crime? To ascertain the evidence on this topic, we conducted an in-depth literature review using the PRISMA checklist. The search parameters included US articles written in English and published since 2000. More than 30,000 potential paper titles were identified and ultimately, 45 papers were selected for inclusion. Green spaces typically comprised tree cover, parks and ground cover. Criminal behaviors typically included murder, assault, and theft. The majority of the research reviewed involved quantitative methods (e.g., comparison of green space area to crime data). We extracted multiple mechanisms from the literature that may account for the impact of green space on crime including social interaction and recreation, community perception, biophilic stress reduction, climate modulation, and spaces expressing territorial definition. Recommendations are made for future research, such as meta-analysis of existing data and the development of grounded theory through qualitative data-gathering methods. By providing evidence that access to nature has a mitigating impact on violence in urban settings, city governments and communities are empowered to support these interventions.

Oral Tranexamic Acid Reduces Transfusions in Total Knee Arthroplasty.

BACKGROUND: Tranexamic acid (TXA) reduces intraoperative blood loss and transfusions in patients undergoing total knee arthroplasty. Although numerous studies demonstrate the efficacy of intravenous and topical TXA in these patients, few demonstrate the effectiveness and appropriate dosing recommendations of oral formulations. METHODS: A retrospective cohort study was performed to evaluate differences in transfusion requirements in patients undergoing primary unilateral total knee arthroplasty with either no TXA (n = 866), a single-dose of oral TXA (n = 157), or both preoperative and postoperative oral TXA (n = 1049). Secondary outcomes included postoperative hemoglobin drop, total units transfused, length of stay, drain output, and cell salvage volume. RESULTS: Transfusion rates decreased from 15.4% in the no-oral tranexamic acid (OTA) group to 9.6% in the single-dose OTA group (P < .001) and 7% in the 2-dose group (P < .001), with no difference in transfusion rates between the single- and 2-dose groups (P = .390). In addition, postoperative hemoglobin drop was reduced from 4.2 g/dL in the no-OTA group to 3.5 g/dL in the single-dose group (P < .01) and to 3.4 g/dL in the 2-dose group (P < .01), without a difference between the single- and 2-dose groups (P = .233). CONCLUSION: OTA reduces transfusions, with greater ease of administration and improved cost-effectiveness relative to other forms of delivery.

Midodrine in patients with spinal cord injury and anejaculation: A double-blind randomized placebo-controlled pilot study.

OBJECTIVE: The objective of this study is to evaluate the efficacy of midodrine in the treatment of anejaculation in men with spinal cord injury (SCI). STUDY DESIGN: Prospective, double-blind, randomized, placebo-controlled pilot study. METHOD: Men with anejaculation associated with SCI (level of injury above T10) of more than 1 year in duration were approached. Those with no ejaculatory response to one penile vibratory stimulation (PVS) trial were assigned in a double-blind manner to one of the two following interventions once a week for a maximum of 3 weeks or until ejaculation occurred: oral administration of flexible midodrine (7.5-22.5 mg max) followed by PVS (group M), or oral administration of flexible sham-midodrine (placebo) followed by PVS (group P). Sociodemographic data, medical characteristics, and plasma desglymidodrine concentration were collected for all participants. OUTCOME MEASURE: Ejaculation success rate in each group. RESULTS: Among the 78 men approached, 23 participants (level of SCI: C4-T9) were randomized. Three participants abandoned the study and 20 completed the study; 10 were assigned to group M, 10 to group P. Ejaculation was reached for one participant of group M and for two participants of group P. Autonomic dysreflexia associated to PVS occurred in three patients. CONCLUSION: In this small sample study, treatment of anejaculation after SCI with midodrine and PVS did not result in a better rate of antegrade ejaculation in 10 men than in 10 men treated with a placebo and PVS.

Spontaneous motor rhythms of the back and legs in a patient with a complete spinal cord transection.

BACKGROUND: Spontaneous activity originating from the spinal cord has been sporadically reported in humans. OBJECTIVES: Investigation of such rhythmic activity of the trunk and legs in a 49-year-old male patient who had a complete severance of the spinal cord at the fifth thoracic vertebra. METHODS: A multichannel electromyography (EMG) study was performed together with kinematics measurements obtained from an Optotrak system. RESULTS: Episodes of rhythmic trunk and lower limb movements started 6 to 7 years after the spinal lesion, recurred at 2 to 3 month intervals, and continued uninterrupted for 2 to 3 days despite continuous delivery of intrathecal baclofen. Several muscles discharged more or less synchronously on both sides but others clearly alternated, for instance, between hip flexors and knee or ankle extensors. Sensory stimuli (hip repositioning or skin pinch) altered significantly the baseline rhythm of about 1 Hz. The patient had both hips injected with corticosteroids and was free of these episodic rhythmic crises for more than 6 months. CONCLUSION: The rhythmic activity observed in the patient appeared related to the activation of a spinal pattern generator akin to what has been described in most animal species after complete spinal lesions.

Perceived physiological and orgasmic sensations at ejaculation in spinal cord injured men.

INTRODUCTION: With the advances in penile vibrator stimulation (PVS), most spinal cord injured (SCI) men can self-ejaculate. Oral midodrine may further increase ejaculation success, while maintaining autonomy. Since most SCI men attempt ejaculation for sexual rather than reproductive purposes, self-ejaculation should be emphasized and sensations explored. AIMS: Explore (i) self-ejaculation success rate in SCI men; (ii) vascular parameters indicative of autonomic dysreflexia (AD) during sexual stimulation and ejaculation; and (iii) sensations associated with ejaculation. METHODS: Ejaculation was assessed on 81 SCI men with complete ASIA A (49%) and incomplete B to D lesions (51%), subdivided into tetraplegics (C2-T2), paraplegics sensitive to AD (T3-T6), paraplegics not sensitive to AD (T7-T10), paraplegics with lesions to the emission pathway (T11-L2), and paraplegics with lesions interrupting the emission-ejaculation pathways (L3-below). Natural stimulation was attempted first followed, if negative, by PVS followed, if again negative, by PVS combined with oral midodrine (5-25 mg). MAIN OUTCOME MEASURES: Ejaculation success, systolic and diastolic blood pressure, and perceived physiological and orgasmic sensations. RESULTS: Overall 91% reached ejaculation, 30% with natural stimulation, 49% with PVS and 12% with midodrine plus PVS. Midodrine salvaged up to 27% depending upon the lesion. Physiological and orgasmic sensations were perceived significantly more at ejaculation than sexual stimulation. Tetraplegics did not differ from paraplegics sensitive to AD on perceived cardiovascular and muscular sensations, but perceived significantly more autonomic sensations, and generally more physiological sensations than lower lesions unsensitive to AD. CONCLUSION: Most SCI men can self-ejaculate and perceive physiological and orgasmic sensations. The climactic experience of ejaculation seems related to AD, few sensations being reported when AD is not reached, pleasurable climactic sensations being reported when mild to moderate AD is reached, and unpleasant or painful sensations reported with severe AD. Sexual rehabilitation should emphasize self-ejaculation and self-exploration and consider cognitive reframing to maximize sexual perceptions.

From aquatic to terrestrial food webs: decrease of the docosahexaenoic acid/linoleic acid ratio.

Fatty acid composition of the adipose tissue of six carnivorous mammalian species (European otter Lutra lutra, American mink Mustela vison, European Mink Mustela lutreola, European polecat Mustela putorius, stone marten Martes foina and European wild cat Felis silvestris) was studied. These species forage to differing degrees in aquatic and terrestrial food webs. Fatty acid analysis revealed significant differences in polyunsaturated fatty acid composition between species. More specifically, our results underline a gradual significant decrease in the docosahexaenoic acid (DHA)/linoleic acid (LNA) ratio of carnivore species as their dependence on aquatic food webs decreases. In conclusion, the use of the DHA/LNA ratio in long-term studies is proposed as a potential proxy of changes in foraging behaviour of semi-aquatic mammals.
