Dispersal polymorphism and mutation play significant roles during biological invasions, potentially leading to evolution and complex behaviour such as accelerating or decelerating invasion fronts. However, life-history theory predicts that reproductive fitness-another key determinant of invasion dynamics-may be lower for more dispersive strains. Here, we use a mathematical model to show that unexpected invasion dynamics emerge from the combination of heritable dispersal polymorphism, dispersal-fitness trade-offs, and mutation between strains. We show that the invasion dynamics are determined by the trade-off relationship between dispersal and population growth rates of the constituent strains. We find that invasion dynamics can be 'anomalous' (i.e. faster than any of the strains in isolation), but that the ultimate invasion speed is determined by the traits of, at most, two strains. The model is simple but generic, so we expect the predictions to apply to a wide range of ecological, evolutionary, or epidemiological invasions.Objective Asynchronous telepsychiatry (ATP) is an integrative model of behavioral health service delivery that is applicable in a variety of settings and populations, particularly consultation in primary care. https://www.selleckchem.com/products/pkr-in-c16.html This article outlines the development of a training model for ATP clinician skills. Methods Clinical and procedural training for ATP clinicians (n = 5) was provided by master's-level, clinical mental health providers developed by three experienced telepsychiatrists (P.Y. D.H., and J.S) and supervised by a tele-psychiatrist (PY, GX, DL) through seminar, case supervision, and case discussions. A training manual and one-on-one sessions were employed for initial training. Unstructured expert discussion and feedback sessions were conducted in the training phase of the study in year 1 and annually thereafter over the remaining 4 years of the study. The notes gathered during those sessions were synthesized into themes to gain a summary of the study telepsychiatrist training recommendations for ATP interviewersioral health services are needed. Clinical Trials number NCT03538860.Objective To examine the prospective association between constipation and risk of developing lower urinary tract symptoms (LUTS) in parous middle-aged women. Materials and Methods The study uses data from 3,729 women from the Avon Longitudinal Study of Parents and Children who provided self-reports of medication intake for constipation at two time points (Baseline) 2001-2003 and 2003-2005. Women with LUTS at baseline were excluded. After 10 years of follow-up, women provided self-reports of LUTS using an adapted version of the International Consultation on Incontinence Questionnaire on Female LUTS. LUTS were categorized according to International Continence Society definitions as stress urinary incontinence (UI), urgency UI, mixed UI, nocturia, increased daytime frequency, urgency, hesitancy, and intermittency. LUTS were considered present if symptoms were reported to occur at least "sometimes" for all subtypes, except for increased daytime frequency (≥9 times) and nocturia (≥2 times nightly). Results At follonstipation to reduce their consequent risk of developing these LUTS.

Approximately 20% of caregivers (CGs) live > 1 hour away from the patient and are considered distance caregivers (DCGs) who often report higher distress and anxiety than local CGs. The purpose of this study was to test the effectiveness of an intervention aimed at reducing anxiety and distress in DCGs of patients with cancer.

This randomized controlled trial enrolled DCGs of patients with all cancer types who were being seen monthly by oncologists in outpatient clinics. There were three arms of the intervention delivered over a 4-month period arm 1 (a) received 4 monthly videoconference-tailored coaching sessions with an advanced practice nurse or social worker focused on information and support, (b) participated in patient's appointments with the oncologist via videoconference over the 4-month study period, and (c) had access to a website designed for DCGs. Arm 2 did not receive the coaching sessions but received the other two components, and arm 3 received access to the DCG website only.

There were 302 DCGs who provided pre- and postintervention data. There were significant anxiety by group (

= .028 and

= 0.16) and distress by group interactions (

= .014 and

= 0.17). Arm 1 had the greatest percentage of DCGs who demonstrated improvement in anxiety (18.6%) and distress (25.2%).

Coaching and use of videoconference technology (to join the DCG into the patient-oncologist office visit) were effective in reducing both anxiety and distress for DCGs. These components could be considered for local CGs who-with COVID-19-are unable to accompany the patient to oncologist visits.

The extensive pressure of managing health care during the pandemic establishes the need for rapid implementation of telemedicine. Across our large statewide practice of 640 practitioners at 221 sites of service, an aggressive multidisciplinary telemedicine strategy was implemented in March by coordinating and training many different parts of our healthcare delivery system. From March to September, telemedicine grew to serve 15%-20% of new patients and 20%-25% of established patients, permitting the practice to implement safety protocols and reduce volumes in clinic while continuing to manage the acute and chronic care needs of our patient population. We surveyed practice leaders, queried for qualitative feedback, and established 76% were satisfied with the platform. The common challenges for patients were the first-time use and technology function, and patients were, in general, grateful and happy to have the option to visit their clinicians on a telemedicine platform.
