ABSTRACT

BACKGROUND: Vasospasm (VS) in microsurgery is a source of surgical complications, repeat operations, stress for the patient and the surgical team, as well as increased length of stay. Various risk factors have been identified but knowledge regarding the implicated mechanism remains limited.

HYPOTHESIS: Our objective was to determine if the harvesting conditions for microsurgical toe transfers could increase the risk of VS. Our secondary objective was to determine the correlation between VS occurrence before flap division, and the occurrence of vascular complications after completion of vascular anastomoses.

PATIENTS AND METHODS: Primary endpoints were the existence of locoregional anaesthesia of the lower limb, the Gilbert classification, the nature of the graft taken from the foot, the characteristics of the patients and smoking status. Our secondary endpoints were the presence of secondary VS or microsurgical failure. This series consists of 14 toe transfers over a 30-month period. Primary VS was defined as occurring prior to flap division, while secondary VS occurred after transfer.

RESULTS: In this series, we identified 4 cases of primary VS. The average age of the operated population was 30.6 ± 11.2 years (16-58). The patients who presented with primary VS had a mean age of 35.3 ± 16.2 years (21-58), with no statistical difference with the other group (p = 0.54). There was a statistically significant difference between the absence of locoregional anaesthesia and the occurrence of primary VS in toe transfer (p = 0.0008). Microsurgical failure occurred in 1 case. This failure was linked to the presence of a primary VS. Gilbert’s classification and type of graft were not predictive of VS (p = 0.15 and p = 0.08, respectively). The occurrence of secondary VS was statistically linked to the occurrence of primary VS (p = 0.009).

DISCUSSION: The occurrence of VS remains unpredictable and the effectiveness of available treatments is debated in the literature. Faced with the failure of curative treatments, this study aimed to determine predictive factors for VS. The existence of secondary VS, when prolonged and non-responsive to conventional measures, can lead to anastomotic revision. Performing locoregional anaesthesia on the lower limb makes it possible to effectively combat the occurrence of VS. The absence of primary VS was correlated with an absence of secondary VS and an absence of microsurgical failure. In addition to controlling vasospasm, regional anaesthesia provides effective analgesia at the harvesting site.

ABSTRACT

BACKGROUND: Autoimmune hepatitis (AIH) patients can present with advanced fibrosis at diagnosis or may progress to the same if biochemical remission on treatment is not achieved.

METHODS: We conducted a single-center retrospective analysis of 34 pediatrics and 39 adult AIH patients. Three pathologists, blinded to clinical information, reviewed the diagnostic liver biopsy (DLB) slides of AIH patients. We evaluated the impact of clinical, laboratory, and histopathologic parameters on outcomes including biochemical remission (BR).

RESULTS: Incidence of advanced (Ludwig stage 3 or 4) fibrosis on DLB was 45.2%. AIH patients with advanced fibrosis had higher median Ishak score (p<0.001) and higher IgG level (p=0.01) at diagnosis. The incidence of BR at 6-month (31.2% vs. 88.6%, p=0.001) and 1-year (68.8% vs. 88.6%, p=0.04) post-diagnosis was significantly lower in AIH patients with advanced fibrosis. Although not statistically significant, a higher proportion of AIH patients with advanced fibrosis were on high dose of steroids (58% vs. 37.9%, p=0.1) at 1 year post diagnosis. Higher serum IgG level at diagnosis was associated with lower odds of achieving BR at 6-month (p = 0.004) and 1-year (p=0.03) post-diagnosis in multivariate analysis. Pediatric age at diagnosis (p=0.02) was associated with higher steroid dose at 1-year post-diagnosis in univariate analysis.

CONCLUSIONS: Findings of advanced fibrosis on DLB of AIH patients was accompanied by more pronounced necro-inflammatory activity and higher serum IgG level, which translated to lower rates of BR and higher exposure to steroids during the first year after diagnosis.

ABSTRACT

Marine Animal Forests (MAFs) form three-dimensional seascapes and provide substrate and shelter for a variety of species. We investigated the fine-scale distribution pattern of three habitat-forming species of the coastal Mediterranean MAFs: Eunicella cavolini, E. singularis and Paramuricea clavata, and assessed the influence of terrain, oceanographic, and biological factors on their distribution and the formation of MAFs in the central-northern Tyrrhenian Sea. Species presence and abundance were obtained through seafloor HD imagery and were combined with terrain and oceanographic parameters extracted from remote sensing data using distance-based linear modeling (DistLM) and generalized additive model (GAM). The three studied species occurred in all the study areas, with marked differences in their abundance and distribution across the different sites and habitat type, in relation to seafloor characteristics. Specifically, positive relationships emerged between the density of colonies and terrain parameters indicative of high seafloor complexity, such as slope and roughness, as well as the number species structuring MAFs. A clear niche separation for the three species was observed: E. cavolini and P. clavata were reported on coralligenous reefs, and in areas where the seafloor complexity may enhance hydrodynamics and transport of organic matter, while E. singularis was observed on red algal mats at shallower depths. A better understanding of the ecology of these gorgonians, as well as of the drivers determining MAFs formation, represent the first step toward the conservation of these threatened habitats which are currently poorly protected by management and conservation plans.

ABSTRACT

PURPOSE: This study examines the relationship between chronic cough and vagal hypersensitivity by measuring baseline esophageal motility, with interest in the upper esophageal sphincter (UES).

MATERIALS AND METHODS: Patients undergoing workup for dysphagia were assigned to a chronic cough or control group based on self-reported symptoms. Differences in demographics, medical comorbidities, and high resolution esophageal manometry findings were obtained retrospectively.

RESULTS: 62.5% of our cohort had chronic cough (30/48). There were no significant differences between the two groups with respect to sex, age, and race/ethnicity. Laryngopharyngeal reflux (LPR) was the only statistically significant predictor of CC (OR 74.04, p = 0.010). Cough patients had upper esophageal sphincter relaxation duration (734 ms) significantly longer than the non-cough patients (582 ms; p = 0.03), though both groups had similar upper esophageal mean basal pressure, mean residual pressure, relaxation time-to-nadir, and recovery time. No significant difference was found in the median intrabolus pressure and UES motility mean peak pressure between groups.

CONCLUSION: Subtle differences in high-resolution manometry between patients with and without cough suggest, in line with previous studies, baseline alterations of upper esophageal function may manifest in patients with chronic cough through an undetermined mechanism that may include underlying vagal hypersensitivity. These findings encourage further manometric study examining the relationship between UES dysfunction and chronic cough.

ABSTRACT

INTRODUCTION: Introduction: Renal cell carcinoma (RCC) is a very rare pediatric renal tumor. Robust evidence to guide treatment is lacking and knowledge on targeted therapies and immunotherapy is mainly based on adult studies. Currently, the International Society of Pediatric Oncology-Renal Tumor Study Group (SIOP-RTSG) 2016 UMBRELLA protocol recommends sunitinib for metastatic or unresectable RCC.

METHODS: This retrospective study describes the effects of tyrosine kinase inhibitors (TKI), anti-programmed cell death 1 (PD-(L)1) monoclonal antibodies, and immunotherapeutic regimens in advanced-stage and relapsed pediatric RCC.

RESULTS: Of the 31 identified patients (0-18 years) with histologically proven RCC, 3/31 presented with TNM stage I/II, 8/31 with TNM stage III, and 20/31 with TNM stage IV at diagnosis. The majority were diagnosed with translocation type RCC (MiT-RCC) (21/31) and the remaining patients mainly presented with papillary or clear-cell RCC. Treatment in a neoadjuvant or adjuvant setting, or upon relapse or progression, included mono- or combination therapy with a large variety of drugs, illustrating center specific choices in most patients. Sunitinib was often administered as first choice and predominantly resulted in stable disease (53%). Other frequently used drugs included axitinib, cabozantinib, sorafenib, and nivolumab; however, no treatment seemed more promising than sunitinib. Overall, 15/31 patients died of disease, 12/31 are alive with active disease, and only four patients had a complete response. The sample size and heterogeneity of this cohort only allowed descriptive statistical analysis.

CONCLUSION: This study provides an overview of a unique series of clinical and treatment characteristics of pediatric patients with RCC treated with targeted therapies.

ABSTRACT

BACKGROUND AND CONTEXT: Involving people with lived experience of health conditions and the public (consumers) in health research is supported by policy, practice and research funding schemes. However, consumer involvement programmes in discovery-based preclinical research settings are uncommon. Few formal evaluations of these programmes are reported in the literature.

OBJECTIVE: This study aimed to evaluate an established patient and public involvement programme operating in a major Australian Discovery-Based Medical Research Institute (DBMRI) to inform programme development and the wider field.

DESIGN AND PARTICIPANTS: A multimethods programme evaluation incorporating demographic, descriptive and qualitative data obtained through consumer/researcher co-developed online surveys and semistructured virtual interviews. Programme participants (n = 111) were invited to complete an online survey seeking feedback on their experience of involvement, programme processes and perceived impacts. A purposive sample of 25 participants was interviewed. Descriptive data were analysed using explanatory statistics and qualitative data from surveys and interviews were thematically analysed.

RESULTS: This consumer involvement programme was found to be useful and meaningful for most participants, with specific examples of perceived added value. Consumers most commonly engaged with researchers to inform research development, prepare funding applications or strengthen lay communication of science. Genuine consumer-researcher interactions, relationship development and mutual respect were key elements in a positive experience for participants. Opportunities to ‘give back’, to learn and to ground research in lived experience were identified programme strengths and benefits. Developing researcher training in how to work with consumers, increasing the diversity of the consumer group membership and expanding the range of consumer activities were identified opportunities for improvement. Organisational support and adequate programme resourcing were identified as key enablers.

CONCLUSION: Discovery-based preclinical research is often viewed as being distant from clinical application; therefore, consumer involvement may be considered less relevant. However this study identified value in bringing a strong consumer voice to the discovery-based research process through a coordinated, organisation-wide approach with the potential for application in similar preclinical research settings.

PATIENT OR PUBLIC CONTRIBUTION: Four consumer partners from the DBMRI Consumer Advisory Panel were actively engaged in developing this programme evaluation. Specifically, these consumer partners co-developed and pilot-tested surveys and interview guides, reviewed and commented on project data analysis and reporting and also contributed as co-authors by editing the manuscript.

ABSTRACT

BACKGROUND: Technology has become an integral part of our everyday life, and its use to manage and study health is no exception. Romantic partners play a critical role in managing chronic health conditions as they tend to be a primary source of support.

OBJECTIVE: This study tests the feasibility of using commercial wearables to monitor couples’ unique way of communicating and supporting each other and documents the physiological correlates of interpersonal dynamics (ie, heart rate linkage).

METHODS: We analyzed 617 audio recordings of 5-minute duration (384 with concurrent heart rate data) and 527 brief self-reports collected from 11 couples in which 1 partner had type II diabetes during the course of their typical daily lives. Audio data were coded by trained raters for social support. The extent to which heart rate fluctuations were linked among couples was quantified using cross-correlations. Random-intercept multilevel models explored whether cross-correlations might differ by social contexts and exchanges.

RESULTS: Sixty percent of audio recordings captured speech between partners and partners reported personal contact with each other in 75% of self-reports. Based on the coding, social support was found in 6% of recordings, whereas at least 1 partner self-reported social support about half the time (53%). Couples, on average, showed small to moderate interconnections in their heart rate fluctuations (r=0.04-0.22). Couples also varied in the extent to which there was lagged linkage, that is, meaning that changes in one partner’s heart rate tended to precede changes in the other partner’s heart rate. Exploratory analyses showed that heart rate linkage was stronger (1) in rater-coded partner conversations (vs moments of no rater-coded partner conversations: r_diff=0.13; P=.03), (2) when partners self-reported interpersonal contact (vs moments of no self-reported interpersonal contact: r_diff=0.20; P<.001), and (3) when partners self-reported social support exchanges (vs moments of no self-reported social support exchange: r_diff=0.15; P=.004).

CONCLUSIONS: Our study provides initial evidence for the utility of using wearables to collect biopsychosocial data in couples managing a chronic health condition in daily life. Specifically, heart rate linkage might play a role in fostering chronic disease management as a couple. Insights from collecting such data could inform future technology interventions to promote healthy lifestyle engagement and adaptive chronic disease management.

ABSTRACT

INTRODUCTION: Value-based healthcare (VBHC) focusses on increasing value for patients. Hospitals aim to implement VBHC via value improvement (VI) teams for medical conditions. To determine the patient’s perspective on value, collective patient participation is important in these teams. We therefore evaluated the current state of patient participation in VI teams and share lessons learned.

METHODS: This mixed-methods study was conducted at seven collaborating hospitals in the Netherlands. A questionnaire (the public and patient engagement evaluation tool) was tailored to the study’s context, completed by VI team members (n = 147 from 76 different VI teams) and analysed with descriptive statistics. In addition, 30 semistructured interviews were held with VI team members and analysed through thematic analysis. Data were collected between February 2022 and January 2023 and were triangulated by mapping the quantitative results to the interview themes.

RESULTS: Thirty-eight of the 76 included VI teams reported using a form of patient participation. Many respondents (71%) indicated a lack of a clear strategy and goal for patient participation. Multiple VI team members believed that specific knowledge and skills are required for patients to participate in a VI team, but this led to concerns regarding the representativeness of participating patients. Furthermore, while patients indicated that they experienced some level of hierarchy, they also stated that they did not feel restricted hereby. Lastly, patients were satisfied with their participation and felt like equal VI team members (100%), but they did mention a lack of feedback from the VI team on their input.

CONCLUSION: The results imply the lack of full implementation of patient participation within VI teams. Guidelines should be developed that provide information on how to include a representative group of patients, which methods to use, how to evaluate the impact of patient participation, and how to give feedback to participating patients.

PATIENT AND PUBLIC CONTRIBUTION: Two patient advisors were part of the research team and attended the research team meetings. They were involved as research partners in all phases of the study, including drafting the protocol (e.g., drafting interview guides and selecting the measurement instrument), interpreting the results and writing this article.

ABSTRACT

OBJECTIVES: The aim of this study was to investigate how preoperative chemotherapy affected the serum zinc concentrations in patients with pancreatic cancer (PC).

METHODS: Two hundreds and thirty-one patients with PC who underwent pancreatectomy at our department from 2013 to 2019 were enrolled in this study and measured for the serum zinc concentrations before pancreatectomy. Patient characteristics, course of treatment, and laboratory data were analyzed.

RESULTS: One hundred thirty-five patients underwent upfront pancreatectomy and 58 received preoperative Gemcitabine + S1 (GEM + S1) and 29 received Gemcitabine + nab-Paclitaxel (GEM + nab-PTX). Comparing the serum zinc concentrations before and after preoperative treatment, it was found to decrease after treatment with statistical difference (79.3 μg/dl vs. 68.7 μg/dl, p < 0.001). The result was consistent with the investigation for both the patients who received GEM + S1 and those who received GEM + nab-PTX (p = 0.019, p < 0.001, respectively).

CONCLUSIONS: The preoperative chemotherapy consistently reduced the serum zinc concentrations in the PC patients, regardless of their regimen such as GEM + S1 and GEM + nab-PTX. Monitoring the serum zinc concentration and appropriate zinc supplementation may be essential for PC patients undergoing preoperative chemotherapy and pancreatectomy.

ABSTRACT

BACKGROUND: Telehealth abortion has taken on a vital role in maintaining abortion access since the Dobbs v. Jackson Women’s Health Organization Supreme Court decision. However, little remains known about the landscape of new telehealth-only virtual clinic abortion providers that have expanded since telehealth abortion first became widely available in the United States in 2021.

OBJECTIVE: This study aimed to (1) document the landscape of telehealth-only virtual clinic abortion care in the United States, (2) describe changes in the presence of virtual clinic abortion services between September 2022, following the Dobbs decision, and June 2023, and (3) identify structural factors that may perpetuate inequities in access to virtual clinic abortion care.

METHODS: We conducted a repeated cross-sectional study by reviewing web search results and abortion directories to identify virtual abortion clinics in September 2022 and June 2023 and described changes in the presence of virtual clinics between these 2 periods. In June 2023, we also described each virtual clinic’s policies, including states served, costs, patient age limits, insurance acceptance, financial assistance available, and gestational limits.

RESULTS: We documented 11 virtual clinics providing telehealth abortion care in 26 states and Washington DC in September 2022. By June 2023, 20 virtual clinics were providing services in 27 states and Washington DC. Most (n=16) offered care to minors, 8 provided care until 10 weeks of pregnancy, and median costs were US $259. In addition, 2 accepted private insurance and 1 accepted Medicaid, within a limited number of states. Most (n=16) had some form of financial assistance available.

CONCLUSIONS: Virtual clinic abortion providers have proliferated since the Dobbs decision. We documented inequities in the availability of telehealth abortion care from virtual clinics, including age restrictions that exclude minors, gestational limits for care, and limited insurance and Medicaid acceptance. Notably, virtual clinic abortion care was not permitted in 11 states where in-person abortion is available.
