Rural patients' experiences with anesthesia and surgical consultations in British Columbia: A survey-based comparison between virtual and in-person modalities.

Introduction: Rural patients face barriers to accessing surgical care and often need to travel long distance for pre- or post-surgical consultations. Although adaptation to the COVID-19 pandemic has demonstrated the efficacy of virtual care, there is minimal data available to evaluate patient satisfaction with this modality and consequent health service utilization if virtual services are not available. Methods: An online survey was conducted with participants living in rural British Columbia, Canada who had undergone surgery within 12 months of data collection and had either virtual or face-to-face pre- or post-surgical consultations. It was supplemented by an in-person survey administered in two rural sites to all patients who had a virtual visit prior to undergoing procedural care. A ten-point scale was used to assess satisfaction. Quantitative and qualitative data were collected and analyzed. Results: Findings from the province-wide survey (n = 163) revealed no significant differences in average satisfaction ratings between people with in-person and virtual surgical consultations (8.03 versus 8.38, p = 0.26). However, most participants indicated that virtual appointments saved them time traveling, energy, and money and made them less dependent on others, accruing significant social benefit.In the community-focused sample (n = 71), 38% said they would not have had the procedure without a virtual visit option and 21% said that they would have delayed the procedure. Virtual consultations saved patients an average of 9 h (range 1-90). Participants traveled an average of 427 kilometers round trip to have the procedures. Conclusion: Findings reveal costs and time saved in accessing care due to the introduction of pre- and post-operative virtual care visits, and further investments in virtual care are warranted. This will contribute to promoting equitable access to healthcare for rural residents.

Perinatal Outcomes at Rural Hospitals That Participated in the Rural Surgical and Obstetrical Networks (RSON) of British Columbia (2016-2021).

BACKGROUND: The goal of the Rural Surgical and Obstetrical Networks (RSON) of British Columbia was to support safe and appropriate surgery, operative birth, and perinatal care closer to home for rural communities. Family physicians with enhanced obstetrical and/or surgical skills provide cesarean delivery and family practice anesthetists manage anesthesia for labour pain and operative births at RSON-supported hospitals, with the involvement of a local specialist at one site. OBJECTIVES: The objectives of the study were to: (1) compare perinatal outcomes at hospitals participating in the RSON initiative with outcomes at referral hospitals and (2) examine temporal changes in the proportion of childbearing people who resided in RSON communities and gave birth locally. METHODS: Poisson regression analysis was used to model the effect of hospital type (RSON vs. referral) on perinatal outcomes. We restricted the analysis to singleton births and controlled for differences in maternal characteristics, obstetric history, and pregnancy complications. RESULTS: Childbearing people who gave birth at RSON-supported hospitals (n = 3498) had a 10% lower incidence of adverse maternal-newborn outcomes compared to those who gave birth at referral hospitals (n = 14 772), after controlling for referral bias. We found a small increase (3.2 %) in the proportion of local births over the study period. CONCLUSION: Findings provide evidence that childbearing people can safely give birth at smaller rural hospitals in British Columbia and that investments in rural hospitals contribute to service stability. Stabilizing local birth services in rural communities benefits the whole region because it reduces surgical overload in regional referral centres.

Case report: Asymptomatic renal arteriovenous fistula requiring endovascular embolization in a living donor transplanted kidney more than 15-years after last protocol biopsy.

Here we present the case of an HLA-identical living-donor kidney transplant recipient, who was incidentally found to have a large complex renal arteriovenous fistula (RAVF) in their transplanted kidney that had been present for nearly 6 years but was previously misinterpreted as being part of a collection of cysts. This patient had undergone 7 protocol biopsies of the transplanted kidney, the last of which had been performed approximately 16 years prior, representing the longest interval between most recent biopsy renal allograft to RAVF diagnosis in the literature date. This report reviews the etiology and principles of management for RAVF.

Fenretinide corrects the imbalance between omega-6 to omega-3 polyunsaturated fatty acids and inhibits macrophage inflammatory mediators via the ERK pathway.

We previously identified Fragile X-related protein 1 (FXR1) as an RNA-binding protein involved in the post-transcriptional control of TNF and other cytokines in macrophages. Macrophages derived from FXR1-KO mice overexpress several inflammatory cytokines including TNF. Recently, we showed that fenretinide (4HPR) is able to inhibit several inflammatory cytokines in the lungs of cystic fibrosis mice, which also have abnormal immune responses. Therefore, we hypothesized that 4HPR might also be able to downregulate excessive inflammation even in macrophages with ablated FXR1. Indeed, our results demonstrate that 4HPR inhibited the excessive production of inflammatory mediators, including TNF, IL-6, CCL2 and CCL-5 in LPS-stimulated FXR1-KO macrophages, by selectively inhibiting phosphorylation of ERK1/2, which is naturally more phosphorylated in FXR1-KO cells. We also found that LPS stimulation of FXR1-KO macrophages led to significantly higher ratio of arachidonic acid/docosahexaenoic acid than observed in FXR1-WT macrophages. Interestingly, treatment with 4HPR was associated with the normalization of arachidonic acid/docosahexaenoic acid ratio in macrophages, which we found to impact phosphorylation of ERK1/2. Overall, this study shows for the first time that 4HPR modulates inflammatory cytokine expression in macrophages by correcting a phospholipid-bound fatty acid imbalance that impacts the phosphorylation of ERK1/2.
