Bladder debris and CD dysfunction were due to the inflammatory response, as neither was observed in Tlr4-deficient (C3H-HeJ) mice. The effect of NH4 Cl-A was unrelated to acidosis as dietary administration of hydrochloric acid (HCl-A) yielded a comparable acid-base status yet did not increase UPEC burden. NH4 Cl-A increased polyamines and decreased nitric oxide (NO) metabolites in urine indicating that excess dietary ammonium shifts arginine metabolism toward polyamines at the expense of NO synthesis. Furthermore, despite increased expression of NOS2, NO production post UPEC infection was attenuated in NH4 Cl-A mice compared to controls. Thus, in addition to induction of metabolic acidosis and urine acidification, excess dietary ammonium alters the polyamineNO balance and thereby compromises NOS2-mediated innate immune defense.Light availability drives vertical canopy gradients in photosynthetic functioning and carbon (C) balance, yet patterns of variability in these gradients remain unclear. We measured light availability, photosynthetic CO2 and light response curves, foliar C, nitrogen (N) and pigment concentrations, and the photochemical reflectance index (PRI) on upper and lower canopy needles of white spruce trees (Picea glauca) at the species' northern and southern range extremes. We combined our photosynthetic data with previously published respiratory data to compare and contrast canopy C balance between latitudinal extremes. We found steep canopy gradients in irradiance, photosynthesis and leaf traits at the southern range limit, but a lack of variation across canopy positions at the northern range limit. Thus, unlike many tree species from tropical to mid-latitude forests, high latitude trees may not require vertical gradients of metabolic activity to optimize photosynthetic C gain. Consequently, accounting for self-shading is less critical for predicting gross primary productivity at northern relative to southern latitudes. Thiamet G Northern trees also had a significantly smaller net positive leaf C balance than southern trees suggesting that, regardless of canopy position, low photosynthetic rates coupled with high respiratory costs may ultimately constrain the northern range limit of this widely distributed boreal species.Severe mechanical ocular trauma with no light perception (NLP) predicts a poor prognosis of visual acuity and enucleation of the eyeball. Since the innovative treatment concept of exploratory vitreoretinal surgery has developed and treatment technology has advanced, the outcomes of severe ocular trauma treatment in NLP patients have greatly improved. However, there remains a lack of unified standards for the determination, surgical indication, and timing of vitrectomy in NLP eye treatment. To address these problems, we aimed to create evidence-based medical guidelines for the diagnosis, treatment, and prognosis of mechanical ocular trauma with NLP. Sixteen relevant recommendations for mechanical ocular trauma with NLP were obtained, and a consensus was reached. Each recommendation was explained in detail to guide the treatment of mechanical ocular trauma associated with NLP.Through reflexive thematic analysis, this study explored three forms of social support in the lives of parentally bereaved youth support derived from one's spirituality, caregiver support via parent-child communication, and therapist support from grief counseling (N = 30 youth, Mage = 12.5 years, SD = 2.8 years). Results showed that these sources of support serve varied and vital functions in the lives of parentally bereaved youth. Namely, the benefits of grief counseling and spirituality were consistently identified by youth as critical in facilitating their coping with the loss of a parent; while parent-child communication regarding the deceased varied widely, highlighting the need for additional supports beyond their surviving caregiver. Findings also revealed differences among these supports across youth gender, race, ethnicity, and age. Adolescents were more likely to disengage from counseling services and reported less parental and spiritual support. Males and minoritized youth experienced more benefits from spiritual and therapist supports.Solving diagnostic errors is difficult and progress on preventing those errors has been slow since the 2015 National Academy of Medicine report. There are several methods used to improve diagnostic and other errors including voluntary reporting; malpractice claims; patient complaints; physician surveys, random quality reviews and audits, and peer review data which usually evaluates single cases and not the systems that allowed the error. Additionally, manual review of charts is often labor intensive and reviewer dependent. In 2010 we developed an e-Autopsy/e-Biopsy (eA/eB) methodology to aggregate cases with quality/safety/diagnostic issues, focusing on a specific population of patients and conditions. By performing a hybrid review process (cases are first filtered using administrative data followed by standardized manual chart reviews) we can efficiently identify patterns of medical and diagnostic error leading to opportunities for system improvements that have improved care for future patients. We present a detailed methodology for eA/eB studies and describe results from three successful studies on different diagnoses (ectopic pregnancy, abdominal aortic aneurysms, and advanced colon cancer) that illustrate our eA/eB process and how it reveals insights into creating systems that reduce diagnostic and other errors. The eA/eB process is innovative and transferable to other healthcare organizations and settings to identify trends in diagnostic error and other quality issues resulting in improved systems of care.The prevalence of obesity is higher among Black women (56.6%) compared to Hispanic women (50%) and non-Hispanic White women (42%). Notably, interventions to reduce obesity typically result in initial weight loss that is not maintained. This study tested (a) the effectiveness of a 6-month Health-Smart Weight Loss (HSWL) Program for Black women patients with obesity implemented by community health workers (CHWs) within primary care clinics and (b) the comparative effectiveness of two 12-month physician-implemented weight loss maintenance programs-a Patient-Centred Culturally Sensitive Weight Loss Maintenance Program (PCCS-WLM Program) and a Standard Behavioural Weight Loss Maintenance Program (SB-WLM Program). Black women patients (N = 683) with obesity from 20 community primary care clinics participated in the HSWL Program and were then randomized to either maintenance program. The HSWL Program led to significant weight loss (i.e., 2.7 pounds, 1.22 kg, p  less then  .01, -1.1%) among the participants. Participants in both the PCCS-WLM Program and the SB-WLM Program maintained their weight loss; however, at month 18, participants in the PCCS-WLM Program had a significantly lower weight than those in the SB-WLM (i.e., 231.9 vs. 239.4 pounds or 105.19 vs. 108.59 kg). This study suggests that (a) the HSWL Program can produce significant weight loss among Black women patients with obesity when implemented in primary care clinics by CHWs, and (b) primary care physicians can be trained to successfully promote weight loss maintenance among their Black women patients.Cynicism and burnout are well-described among new medical school graduates. At the new medical school in Washington state, the trend toward placing importance on wellness and creating a culture of healing was present from the outset. To encourage reflective practice, Balint groups were introduced as a method to teach students to think deeply about patient relationships and to address particular curricular objectives, including to demonstrate empathy for healthcare trainees and for patients, and to practice active listening skills in the context of the student Balint groups. The approach presented here will focus on the introduction of Balint groups into the pre-clerkship curriculum as a longitudinal tool to prepare students to use the method with more facility in their clerkships. The presentation at the 2022 American Balint Society Annual Meeting highlighted the introduction of Balint groups to the clinician faculty using the Intensive on the Road format, the introduction of Balint groups to pre-clerkship medical students, and the use of Balint groups in the pre-clerkship curriculum. The operational aspects, including faculty recruitment and retention, as well as student groupings and scheduling, were addressed in the context of the overall theme of monitoring student progress toward open communication about their challenging patient relationships. Programmatic evaluation and current trends were emphasized, along with the anticipated evolution and future directions of the program at our community-based medical school.Cross-sectional data indicate that acute SARS-CoV-2 infection increases resting muscle sympathetic nerve activity (MSNA) and alters hemodynamic responses to orthostasis in young adults. However, the longitudinal impact of contracting SARS-CoV-2 on autonomic function remains unclear. The aim of this study was to longitudinally track MSNA, sympathetic transduction to blood pressure (BP), and hemodynamics over 6 months following SARS-CoV-2 infection. Young adults positive with SARS-CoV-2 reported to the laboratory three times over 6 months (V141 ± 17, V2108 ± 21, V3173 ± 16 days post-infection). MSNA, systolic (SBP) and diastolic (DBP) blood pressure, and heart rate (HR) were measured at rest, during a cold pressor test (CPT), and at 30° head-up tilt (HUT). Basal SBP (p = 0.019) and DBP (p less then  0.001) decreased throughout the 6 months, whereas basal MSNA and HR were not different. Basal sympathetic transduction to BP and estimates of baroreflex sensitivity did not change over time. SBP and DBP were lower during CPT (SBP p = 0.016, DBP p = 0.007) and HUT at V3 compared with V1 (SBP p = 0.041, DBP p = 0.017), with largely no changes in MSNA. There was a trend toward a visit-by-time interaction for burst incidence (p = 0.055) during HUT, wherein at baseline immediately prior to tilting, burst incidence was lower at V3 compared with V1 (p = 0.014), but there were no differences between visits in the 30 HUT position. These results support impairments to cardiovascular health, and potentially autonomic function, which may improve over time. However, the improvements in BP over 6 months recovery from mild SARS-CoV-2 infection are likely not a direct result of changes in sympathetic activity.This mixed method sequential study reports focus group and pilot intervention findings that (1) explore the views of persons with dementia and their caregivers on using a self-directed advance care planning engagement workbook (Your Conversation Starter Kit) and (2) uncover the conditions that encouraged and hindered workbook use. In Phase 1, we conducted five focus groups consisting of 10 persons with dementia and eight family members/caregivers from two urban Canadian cities to explore overall impressions of the workbook and factors that might affect its use. In Phase 2, we empirically explored the factors identified in Phase 1 by distributing the workbook to 24 persons with dementia. The combined findings suggest that the workbook offers promise in supporting advance care planning engagement for persons with dementia in the early stages of their condition. Involving family/caregivers and clarifying some of the ranked questions might improve the workbook's use. Persons with dementia without familial support or those who have never contemplated advance care planning may require additional guidance prior to workbook distribution.
