Spatial population dynamics of western painted turtles in a wetland ecosystem in northwestern Montana

Population dynamics are driven by the interplay between the positive forces of births and immigration and the negative forces of deaths and emigration. Understanding dynamics at the local and metapopulation level is key in wildlife conservation. Although data on turtle survival and movement rates are available, few studies use rigorous statistical analyses and none include examination of stage-specific seasonal survival simultaneous with movement estimates. I used capture-mark-recapture methods to estimate apparent survival rates and movement probabilities of adult and juvenile western painted turtles (Chrysemys picta bellii) across space and time in a wetland ecosystem in northwestern Montana. All wetlands within five complexes were sampled during three primary sessions a year from fall 2002 to spring 2005. I captured 1,072 individual adults 5,050 times and 442 individual juveniles 3,078 times. Although both juvenile and adult apparent survival rates were influenced by pond, seasons, and year, I found very different patterns spatially and seasonally between age classes. Apparent annual survival was lowest for adults in shallow ponds and lowest for juveniles in deep ponds. This variation could be due to mobility of adults which allows them to seek refugia habitats during drought conditions. Juveniles were less mobile and less likely to leave ponds. Movement probabilities of adults were influenced by distance between ponds and depth of originating pond. Only two juveniles were observed to move between complexes. Although the highest interpopulation movement probability was 3.8%, the probability for most interpopulation movements was very low (\u3c 1%). Temporary emigration estimates were higher than estimates of interpopulation movement indicating the importance of refugia habitat. I examined the potential impacts of road mortality on both the overall population size and population structure via sex and stage class ratios of this population. Road mortality averaged 185 individuals/year. Annual road mortalities ranged widely depending on pond characteristics but in general were higher than the 2-3% mortality suggested by other research to likely affect long-term viability in turtle populations. No highway-induced sex-bias occurred in this population. Population growth rates were negatively influenced by the presence of roads and positively influenced by movements

Impact of Community Health Workers on Elderly Patients' Advance Care Planning and Health Care Utilization: Moving the Dial

BACKGROUND: Advance care planning (ACP) is recommended for all persons to ensure that the care they receive aligns with their values and preferences. OBJECTIVE: To evaluate an ACP intervention developed to better meet the needs and priorities of persons with chronic diseases, including mild cognitive impairment. RESEARCH DESIGN: A year-long, pre-post intervention using lay community health workers [care coordinator assistants (CCAs)] trained to conduct and document ACP conversations with patients during home health visits with pre-post evaluation. SUBJECTS: The 818 patients were 74.2 years old (mean); 78% women; 51% African American; 43% white. MEASURES: Documentation of ACP conversation in electronic health record fields and health care utilization outcomes. RESULTS: In this target population ACP documentation rose from 3.4% (pre-CCA training) to 47.9% (post) of patients who had at least 1 discussion about ACP in the electronic health record. In the 1-year preintervention period, there were no differences in admissions, emergency department (ED) visits, and outpatient visits between patients who did and did not have ACP discussion. After adjusting for prior hospitalization and ED use histories, ACP discussions were associated with a 34% less probability of hospitalization (hazard ratios, 0.66; 95% confidence interval, 0.45-0.97), and similar effects are apparent on ED use independent of age and prior ED use effects. CONCLUSIONS: Patients with chronic diseases including mild cognitive impairment can engage in ACP conversations with trusted home health care providers. Having ACP conversation is associated with significant reduction in seeking urgent health care and in hospitalizations

Clarifying Values and Preferences for Care Near the End of Life: The Role of a New Lay Workforce

Community health workers (CHWs) can engage elderly persons in advance care planning (ACP) conversations. We report how trained CHWs used Go Wish cards (GW R cards) to identify patients' highest priority preferences and evaluated whether engaging in ACP conversations was associated with subsequent health care utilization. A one-year long, pre-post longitudinal design was used to evaluate our educational intervention using mixed-methods. 392 patients (mean of 73.3 years, 82% women, 48% African American, 43% Caucasian) enrolled in the Aging Brain Care (ABC) program and participated in ACP discussions with CHWs. We expanded the role of the ABC's CHW, who work directly with individuals and caregivers during home visits to monitor bio-psycho-social needs, to include ACP conversations. The CHWs received ACP training, practice with tools such as GW R cards, and support from an electronic health record (EHR) clinical decision support tool. Quantitative measures of patients' ACP preferences and health care utilization were abstracted from the EHR. Qualitative data about patients' perceptions of CHWs in facilitating ACP discussions was obtained through semi-structured interviews. Eighty-six patients' data indicated that they had engaged in a preferences-for-care process using GW R cards. The top-three card choices by patients was attending to spirituality and religious concerns, preparing for end of life, and maintaining personal wholeness. CHWs were able to effectively engage in ACP conversations with patients and GW R cards were a positive way to stimulate discussion of issues previously undiscussed

Bi-allelic Loss-of-Function CACNA1B Mutations in Progressive Epilepsy-Dyskinesia.

The occurrence of non-epileptic hyperkinetic movements in the context of developmental epileptic encephalopathies is an increasingly recognized phenomenon. Identification of causative mutations provides an important insight into common pathogenic mechanisms that cause both seizures and abnormal motor control. We report bi-allelic loss-of-function CACNA1B variants in six children from three unrelated families whose affected members present with a complex and progressive neurological syndrome. All affected individuals presented with epileptic encephalopathy, severe neurodevelopmental delay (often with regression), and a hyperkinetic movement disorder. Additional neurological features included postnatal microcephaly and hypotonia. Five children died in childhood or adolescence (mean age of death: 9 years), mainly as a result of secondary respiratory complications. CACNA1B encodes the pore-forming subunit of the pre-synaptic neuronal voltage-gated calcium channel Cav2.2/N-type, crucial for SNARE-mediated neurotransmission, particularly in the early postnatal period. Bi-allelic loss-of-function variants in CACNA1B are predicted to cause disruption of Ca2+ influx, leading to impaired synaptic neurotransmission. The resultant effect on neuronal function is likely to be important in the development of involuntary movements and epilepsy. Overall, our findings provide further evidence for the key role of Cav2.2 in normal human neurodevelopment.MAK is funded by an NIHR Research Professorship and receives funding from the Wellcome Trust, Great Ormond Street Children's Hospital Charity, and Rosetrees Trust.

Adding 6 months of androgen deprivation therapy to postoperative radiotherapy for prostate cancer: a comparison of short-course versus no androgen deprivation therapy in the RADICALS-HD randomised controlled trial

Background Previous evidence indicates that adjuvant, short-course androgen deprivation therapy (ADT) improves metastasis-free survival when given with primary radiotherapy for intermediate-risk and high-risk localised prostate cancer. However, the value of ADT with postoperative radiotherapy after radical prostatectomy is unclear. Methods RADICALS-HD was an international randomised controlled trial to test the efficacy of ADT used in combination with postoperative radiotherapy for prostate cancer. Key eligibility criteria were indication for radiotherapy after radical prostatectomy for prostate cancer, prostate-specific antigen less than 5 ng/mL, absence of metastatic disease, and written consent. Participants were randomly assigned (1:1) to radiotherapy alone (no ADT) or radiotherapy with 6 months of ADT (short-course ADT), using monthly subcutaneous gonadotropin-releasing hormone analogue injections, daily oral bicalutamide monotherapy 150 mg, or monthly subcutaneous degarelix. Randomisation was done centrally through minimisation with a random element, stratified by Gleason score, positive margins, radiotherapy timing, planned radiotherapy schedule, and planned type of ADT, in a computerised system. The allocated treatment was not masked. The primary outcome measure was metastasis-free survival, defined as distant metastasis arising from prostate cancer or death from any cause. Standard survival analysis methods were used, accounting for randomisation stratification factors. The trial had 80% power with two-sided α of 5% to detect an absolute increase in 10-year metastasis-free survival from 80% to 86% (hazard ratio [HR] 0·67). Analyses followed the intention-to-treat principle. The trial is registered with the ISRCTN registry, ISRCTN40814031, and ClinicalTrials.gov, NCT00541047. Findings Between Nov 22, 2007, and June 29, 2015, 1480 patients (median age 66 years [IQR 61–69]) were randomly assigned to receive no ADT (n=737) or short-course ADT (n=743) in addition to postoperative radiotherapy at 121 centres in Canada, Denmark, Ireland, and the UK. With a median follow-up of 9·0 years (IQR 7·1–10·1), metastasis-free survival events were reported for 268 participants (142 in the no ADT group and 126 in the short-course ADT group; HR 0·886 [95% CI 0·688–1·140], p=0·35). 10-year metastasis-free survival was 79·2% (95% CI 75·4–82·5) in the no ADT group and 80·4% (76·6–83·6) in the short-course ADT group. Toxicity of grade 3 or higher was reported for 121 (17%) of 737 participants in the no ADT group and 100 (14%) of 743 in the short-course ADT group (p=0·15), with no treatment-related deaths. Interpretation Metastatic disease is uncommon following postoperative bed radiotherapy after radical prostatectomy. Adding 6 months of ADT to this radiotherapy did not improve metastasis-free survival compared with no ADT. These findings do not support the use of short-course ADT with postoperative radiotherapy in this patient population

Duration of androgen deprivation therapy with postoperative radiotherapy for prostate cancer: a comparison of long-course versus short-course androgen deprivation therapy in the RADICALS-HD randomised trial

Background Previous evidence supports androgen deprivation therapy (ADT) with primary radiotherapy as initial treatment for intermediate-risk and high-risk localised prostate cancer. However, the use and optimal duration of ADT with postoperative radiotherapy after radical prostatectomy remains uncertain. Methods RADICALS-HD was a randomised controlled trial of ADT duration within the RADICALS protocol. Here, we report on the comparison of short-course versus long-course ADT. Key eligibility criteria were indication for radiotherapy after previous radical prostatectomy for prostate cancer, prostate-specific antigen less than 5 ng/mL, absence of metastatic disease, and written consent. Participants were randomly assigned (1:1) to add 6 months of ADT (short-course ADT) or 24 months of ADT (long-course ADT) to radiotherapy, using subcutaneous gonadotrophin-releasing hormone analogue (monthly in the short-course ADT group and 3-monthly in the long-course ADT group), daily oral bicalutamide monotherapy 150 mg, or monthly subcutaneous degarelix. Randomisation was done centrally through minimisation with a random element, stratified by Gleason score, positive margins, radiotherapy timing, planned radiotherapy schedule, and planned type of ADT, in a computerised system. The allocated treatment was not masked. The primary outcome measure was metastasis-free survival, defined as metastasis arising from prostate cancer or death from any cause. The comparison had more than 80% power with two-sided α of 5% to detect an absolute increase in 10-year metastasis-free survival from 75% to 81% (hazard ratio [HR] 0·72). Standard time-to-event analyses were used. Analyses followed intention-to-treat principle. The trial is registered with the ISRCTN registry, ISRCTN40814031, and ClinicalTrials.gov , NCT00541047 . Findings Between Jan 30, 2008, and July 7, 2015, 1523 patients (median age 65 years, IQR 60–69) were randomly assigned to receive short-course ADT (n=761) or long-course ADT (n=762) in addition to postoperative radiotherapy at 138 centres in Canada, Denmark, Ireland, and the UK. With a median follow-up of 8·9 years (7·0–10·0), 313 metastasis-free survival events were reported overall (174 in the short-course ADT group and 139 in the long-course ADT group; HR 0·773 [95% CI 0·612–0·975]; p=0·029). 10-year metastasis-free survival was 71·9% (95% CI 67·6–75·7) in the short-course ADT group and 78·1% (74·2–81·5) in the long-course ADT group. Toxicity of grade 3 or higher was reported for 105 (14%) of 753 participants in the short-course ADT group and 142 (19%) of 757 participants in the long-course ADT group (p=0·025), with no treatment-related deaths. Interpretation Compared with adding 6 months of ADT, adding 24 months of ADT improved metastasis-free survival in people receiving postoperative radiotherapy. For individuals who can accept the additional duration of adverse effects, long-course ADT should be offered with postoperative radiotherapy.

“I Don’t Want to Go to Work”: A Mixed-Methods Analysis of HealthcareWorker Experiences from the Front- and Side-Lines of COVID-19

During the COVID-19 pandemic, healthcare workers (HCW) were categorized as “essential” and “non-essential”, creating a division where some were “locked-in” a system with little ability to prepare for or control the oncoming crisis. Others were “locked-out” regardless of whether their skills might be useful. The purpose of this study was to systematically gather data over the course of the COVID-19 pandemic from HCW through an interprofessional lens to examine experiences of locked-out HCW. This convergent parallel mixed-methods study captured perspectives representing nearly two dozen professions through a survey, administered via social media, and video blogs. Analysis included logistic regression models of differences in outcome measures by professional category and Rapid Identification of Themes from Audio recordings (RITA) of video blogs. We collected 1299 baseline responses from 15 April 2020 to 16 March 2021. Of those responses, 12.1% reported no signs of burnout, while 21.9% reported four or more signs. Qualitative analysis identified four themes: (1) professional identity, (2) intrinsic stressors, (3) extrinsic factors, and (4) coping strategies. There are some differences in the experiences of locked-in and locked-out HCW. This did not always lead to differing reports of moral distress and burnout, and both groups struggled to cope with the realities of the pandemic
