Authors: Gerritzen Esther Vera , Kohl Gianna , Orrell Martin , McDermott Orii 
Published: November 2022

Background People with young onset dementia can experience stigmatization and social isolation. Peer support provides an opportunity for social connection and support. However, access to in-person peer support groups varies across the UK, and during the COVID-19 pandemic in-person peer support groups moved online. Objectives We explored the experiences of people with young onset dementia attending peer support meetings through online videoconferencing platforms, and identified barriers and facilitators. Methods A focus group study with existing peer support groups for people with young onset dementia that had their meetings online was conducted. Participants were people living with young onset dementia. Participants were recruited through convenience and purposeful sampling. Initial contact was made with the group facilitator to discuss the study purposes and assess eligibility of the group members. The data was analysed thematically by two independent researchers, using an inductive approach. Findings Four focus groups with UK-based peer support groups were conducted through the group’s usual platform, including 20 participants. Through online peer support people stayed connected during the pandemic. It provided opportunities to meet people from different places and be involved in research projects. People found it a convenient way of connecting with others without having to travel. However, some missed in-person interaction and digital exclusion and challenges to navigate different platforms were identified as barriers. Organisational skills of the facilitator and support with getting into meetings can help overcome these challenges. Conclusion Online platforms can make peer support more accessible for people with young onset dementia as it overcomes geographical barriers as well as barriers for those who feel uncomfortable attending an in-person group. Researchers and policy makers should explore how to implement and overcome barriers to online peer support, so that peer support is more widely accessible and clearly signposted to people with young onset dementia.
Doing Duoethnography: Addressing Essential Methodological Questions
Authors: Burleigh Dawn , Burm Sarah 
Published: November 2022

Duoethnography is a collaborative research methodology that invites researchers to serve as sites of inquiry. Through juxtaposition, the voices of each researcher are made explicit, working in tandem to untangle and disrupt meanings about a particular social phenomenon. We gravitate to duoethnography for its evocative power and the opportunity this methodology provides to engage in meaningful self-study in the presence of another. Yet, we grapple with methodological issues related to the unseen and unspoken enactments of the methodology. This article makes transparent the process of engaging in duoethnography by modeling its polyvocal dialogic nature while simultaneously addressing five essential questions about this collaborative research methodology. In this article, we retrace our collective journey engaging in duoethnography over the past 10 years, reflecting upon how our understanding and engagement with the methodology has shifted and expanded with each new inquiry. We make visible what is often invisible in the process of doing duoethnography, explicitly discussing our process for beginning and concluding a duoethnography, addressing what constitutes duoethnographic data, and the importance of cultivating a trustworthy and safe dialogical space. This article contributes to the existing methodological literature on duoethnography and further substantiates and generates transparency and teachability of this collaborative research approach.

Objective: Radiation-induced lung injury (RILI) is one of the serious complications of radiotherapy. We have recently demonstrated that nicaraven can effectively mitigate RILI in healthy mice. Here, we further tried to optimize the dose and time of nicaraven administration for alleviating the side effects of radiotherapy in tumor-bearing mice. Methods and results: A subcutaneous tumor model was established in the back of the chest in C57BL/6N mice by injecting Lewis lung cancer cells. Therapeutic thoracic irradiations were done, and placebo or different doses of nicaraven (20, 50, 100 mg/kg) were administrated intraperitoneally pre-irradiation (at almost 5–10 min before irradiation) or post-irradiation (within 5 min after irradiation). Mice that received radiotherapy and nicaraven were sacrificed on the 30th day, but control mice were sacrificed on the 15th day. Serum and lung tissues were collected for evaluation. Nicaraven significantly decreased the level of CCL8, but did not clearly change the levels of 8-OHdG, TGF-β, IL-1β, and IL-6 in serum. Besides these, nicaraven effectively decreased the levels of TGF-β, IL-1β, and SOD2 in the lungs, especially by post-irradiation administration with the dose of 20 mg/kg. Although there was no significant difference, the expression of SOD1, 53BP1, and caspase 3 was detected lower in the lungs of mice received nicaraven post-irradiation than that of pre-irradiation. Conclusion: According to our data, the administration of nicaraven at a relatively low dose soon after radiotherapy will be recommended for attenuating the side effects of radiotherapy.

Background: In light of advancements in machine learning techniques, many studies have implemented machine learning approaches combined with data measures to predict and classify Alzheimer’s disease. Studies that predicted cognitive status with longitudinal follow-up of amyloid-positive individuals remain scarce, however. Objective: We developed models based on voxel-wise functional connectivity (FC) density mapping and the presence of the ApoE4 genotype to predict whether amyloid-positive individuals would experience cognitive decline after 1 year. Methods: We divided 122 participants into cognitive decline and stable cognition groups based on the participants’ change rates in Mini-Mental State Examination scores. In addition, we included 68 participants from Alzheimer’s Disease Neuroimaging Initiative (ADNI) database as an external validation data set. Subsequently, we developed two classification models: the first model included 99 voxels, and the second model included 99 voxels and the ApoE4 genotype as features to train the models by Wide Neural Network algorithm with fivefold cross-validation and to predict the classes in the hold-out test and ADNI data sets. Results: The results revealed that both models demonstrated high accuracy in classifying the two groups in the hold-out test data set. The model for FC demonstrated good performance, with a mean F1-score of 0.86. The model for FC combined with the ApoE4 genotype achieved superior performance, with a mean F1-score of 0.90. In the ADNI data set, the two models demonstrated stable performances, with mean F1-scores of 0.77 in the first and second models. Conclusion: Our findings suggest that the proposed models exhibited promising accuracy for predicting cognitive status after 1 year in amyloid-positive individuals. Notably, the combination of FC and the ApoE4 genotype increased prediction accuracy. These findings can assist clinicians in predicting changes in cognitive status in individuals with a high risk of Alzheimer’s disease and can assist future studies in developing precise treatment and prevention strategies.

Published: November 2022

Background: Nivolumab has been approved in China as second-line treatment for advanced non-small-cell lung cancer (NSCLC) via weight-based infusion, based on the CheckMate 078 study. We investigated the safety and efficacy of 240 mg flat-dose nivolumab in patients with advanced NSCLC, including those with hepatitis B virus (HBV) and epidermal growth factor receptor ( EGFR) mutation/ALK receptor tyrosine kinase ( ALK) translocation due to high prevalence in China. Methods: CheckMate 870 was a single-arm, open-label, phase IIIb trial in Asian (primarily Chinese) patients with previously treated advanced NSCLC. Patients received flat-dose nivolumab 240 mg every 2 weeks (Q2W) for up to 2 years. The primary endpoint was the incidence and severity of treatment-related select adverse events (TRsAEs) in non-HBV patients; secondary and exploratory endpoints included severity of high-grade TRsAEs in HBV-infected patients, and safety, efficacy and patient-reported outcomes (PROs) in the whole population. Results: Out of 404 patients enrolled, 400 received treatment. Median (standard deviation) age was 60.5 (8.68) years and the majority were male (78.5%). At a median follow-up of 37.6 months, no Grade 5 TRsAEs were reported, and the frequency of Grade 3–4 TRsAEs was low (0.0–5.9%) in non-HBV and HBV NSCLC patients. Median overall survival (OS) and progression-free survival (PFS) in all treated patients were 14.7 (12.3–18.1) and 3.6 (2.3–3.8) months, respectively. Median OS was 14.2 (12.3–18.1) and 22.3 (10.0–NA) months for non-HBV and HBV-infected patients, 19.3 (11.2–31.7) and 13.7 (11.5–18.1) months for EGFR-positive and wild-type subgroups, and 19.3 (12.9–23.5) and 13.3 (10.9–17.7) months for those with programmed death-ligand 1 (PD-L1) expression ⩾1% and <1%, respectively. No notable changes from baseline were observed in PROs throughout the study. Conclusion: Nivolumab 240 mg infusion Q2W was well tolerated, efficacious, and maintained health status and quality of life in Asian patients with previously treated advanced NSCLC regardless of HBV, EGFR, or PD-L1 status.

Introduction Obstruction of the lacrimal drainage represents a common ophthalmologic issue. The blockage may interest any level of the lacrimal drainage pathway, and it is important to find the site of obstruction to plan the most appropriate treatment. In this study, findings from magnetic resonance (MR) dacryocystography were compared with findings from endoscopic and surgical procedures to evaluate the accuracy of MR dacryocystography in localizing the site of nasolacrimal duct obstruction. Methods We enrolled twenty-one patients with clinical suspicion of nasolacrimal duct obstruction who underwent dacryoendoscopy and surgery. MR dacryocystography was performed with a heavily T2-weighted fast spin echo sequence in the coronal planes. Before the MRI was performed, a sterile 0.9% NaCl solution was administered into both conjunctival sacs. For each examination, two independent readers (with 8 and 10 years of experience in head and neck imaging) evaluated both heavily 3D space T2-weighted and STIR sequences. Results Stenosis/obstruction of nasolacrimal duct or lacrimal sac was diagnosed in all 21 patients who underwent MRI dacryocystography. In particular, the site of the obstruction was classified as lacrimal sac in 12 (57%) patients, nasolacrimal duct in 6 (29%) patients, and canaliculi in 3 (14%) patients by both readers. By comparison with the evidence resulting from the endoscopy, there were differences between MRI dacryocystography and dacryoendoscopy in the evaluation of the obstruction’s site in three patients, with an overall accuracy of 85.7%. Conclusion MR dacryocystography allows a non-invasive evaluation of the lacrimal drainage pathway, valid for the planning of the most appropriate treatment.

Authors: Zazoulina Julia , Khehra Keesha , Gill Jagbir 
Published: November 2022

Background: For patients with end-stage kidney disease, living donor kidney transplant is the treatment of choice due to improved patient outcomes, longer graft survival, and reduced expenses compared with other forms of renal replacement therapy. However, organ shortage remains a challenge, and living donation rates have stagnated in recent years, particularly among men. Objective: To understand the motivators and barriers for past and potential living kidney transplant donors and inform policy and practice changes that support donors in the future. Methods: Past and potential living donors in British Columbia, Canada in the preceding 2 years were surveyed. Motivators and barriers were examined in 5 categories: family pressures and domestic responsibilities, finances, the recovery process, complications, and the transplant evaluation process. Participants ranked statements in each category on a Likert-type scale. Results: A total of 138 responses were collected. In both women and men, policies that address family and domestic responsibilities and finances were most strongly identified as motivators to donate. A large proportion of women and men reported that guaranteed job security (47% women and 38% of men), paid time off (51% of women and 42% of men), reimbursement of lost wages (49% of women and 38% of men), and protections to guarantee no impact on future insurability (62% of women and 52% of men) were significant motivators to donate. Timely and efficient medical evaluation was considered to be an important motivator for donation, with 52% of men and 43% of women reporting support for a “fast-track” option for evaluation to allow for a more rapid evaluation process. Median barrier and motivator scores were similar between women and men. Conclusion: Policies to decrease financial burden, ensure job security, improve childcare support, and offer a fast-track medical evaluation may motivate potential living kidney donors, irrespective of gender.

Introduction and Objective: The lack of precision to identify patients with early-stage diabetic kidney disease (DKD) at near-term risk for progressive decline in kidney function results in poor disease management often leading to kidney failure requiring unplanned dialysis. The KidneyIntelX is a multiplex, bioprognostic, immunoassay consisting of 3 plasma biomarkers and clinical variables that uses machine learning to generate a risk score for progressive decline in kidney function over 5-year in adults with early-stage DKD. Our objective was to assess the impact of KidneyIntelX on management and outcomes in a Health System in the real-world evidence (RWE) study. Methods: KidneyIntelX was introduced into a large metropolitan Health System via a population health-defined approved care pathway for patients with stages 1 to 3 DKD between [November 2020 to March 2022]. Decision impact on visit frequency, medication management, specialist referral, and selected lab values was assessed. We performed an interim analysis in patients through 6-months post-test date to evaluate the impact of risk level with clinical decision-making and outcomes. Results: A total of 1686 patients were enrolled in the RWE study and underwent KidneyIntelX testing and subsequent care pathway management. The median age was 68 years, 52% were female, 26% self-identified as Black, and 94% had hypertension. The median baseline eGFR was 59 ml/minute/1.73 m2, urine albumin-creatinine ratio was 69 mg/g, and HbA1c was 7.7%. After testing, a clinical encounter in the first month occurred in 13%, 43%, and 53% of low-risk, intermediate-risk, and high-risk patients, respectively and 46%, 61%, and 71% had at least 1 action taken within the first 6 months. High-risk patients were more likely to be placed on SGLT2 inhibitors (OR = 4.56; 95% CI 3.00-6.91 vs low-risk), and more likely to be referred to a specialist such as a nephrologist, endocrinologist, or dietician (OR = 2.49; 95% CI 1.53-4.01) compared to low-risk patients. Conclusions: The combination of KidneyIntelX, clinical guidelines and educational support resulted in changes in clinical management by clinicians. After testing, there was an increase in visit frequency, referrals for disease management, and introduction to guideline-recommended medications. These differed by risk category, indicating an impact of KidneyIntelX risk stratification on clinical care.

Abstract
Background
Trigeminal neuralgia is a severe facial pain disorder. Microvascular decompression is first choice surgical treatment of patients with classical TN. There exist few prospective studies with an independent evaluation of efficacy and complications after MVD.

Objectives
We aimed to assess outcome and complications after microvascular decompression from our center.

Methods
We prospectively recorded clinical characteristics, outcome, and complications from consecutive patients with either classical or idiopathic (only patients with a neurovascular contact) trigeminal neuralgia undergoing microvascular decompression. Neurovascular contact was evaluated by 3.0 Tesla MRI. Patients were assessed before and 3, 6, 12, and 24 months after surgery by independent assessors.

Results
Of 115 included patients, 86% had a clinically significant outcome (i.e., BNI I – BNI IIIb). There was a significant association between an excellent surgical outcome and the male sex (OR 4.9 (CI 1.9–12.8), p = 0.001) and neurovascular contact with morphological changes (OR 2.5 (CI 1.1–6.0), p = 0.036). Significantly more women (12/62 = 19%) than men (2/53 = 4%) had a failed outcome, p = 0.019. The most frequent major complications were permanent hearing impairment (10%), permanent severe hypoesthesia (7%), permanent ataxia (7%), and stroke (6%). Most patients (94%) recommend surgery to others.

Conclusion
Microvascular decompression is an effective treatment for classical and idiopathic (only patients with a neurovascular contact) trigeminal neuralgia with a high chance of a long-lasting effect. The chance of an excellent outcome was highest in men and in patients with classical trigeminal neuralgia. Complications are relatively frequent warranting thorough patient evaluation and information preoperatively.

AbstractAdvances in next-generation sequencing technologies have accelerated the momentum of metagenomic studies, which is increasing yearly. The metagenomics field is one of the versatile applications in microbiology, where any interaction in the environment involving microorganisms can be the topic of study. Due to this versatility, the number of applications of this omics technology reached its horizons. Agriculture is a crucial sector involving crop plants and microorganisms interacting together. Hence, studying these interactions through the lenses of metagenomics would completely disclose a new meaning to crop health and development. The rhizosphere is an essential reservoir of the microbial community for agricultural soil. Hence, we focus on the R&D of metagenomic studies on the rhizosphere of crops such as rice, wheat, legumes, chickpea, and sorghum. These recent developments are impossible without the continuous advancement seen in the next-generation sequencing platforms; thus, a brief introduction and analysis of the available sequencing platforms are presented here to have a clear picture of the workflow. Concluding the topic is the discussion about different pipelines applied to analyze data produced by sequencing techniques and have a significant role in interpreting the outcome of a particular experiment. A plethora of different software and tools are incorporated in the automated pipelines or individually available to perform manual metagenomic analysis. Here we describe 8–10 advanced, efficient pipelines used for analysis that explain their respective workflows to simplify the whole analysis process.

Abstract
Background
The cold pressor test (CPT) is a widely used pain provocation test to investigate both pain tolerance and cardiovascular responses. We hypothesize, that performing multi-omic analyses during CPT gives the opportunity to home in on molecular mechanisms involved. Twenty-two females were phenotypically assessed before and after a CPT, and blood samples were taken. RNA-Sequencing, steroid profiling and untargeted metabolomics were performed. Each ‘omic level was analyzed separately at both single-feature and systems-level (principal component [PCA] and partial least squares [PLS] regression analysis) and all ‘omic levels were combined using an integrative multi-omics approach, all using the paired-sample design.

Results
We showed that PCA was not able to discriminate time points, while PLS did significantly distinguish time points using metabolomics and/or transcriptomic data, but not using conventional physiological measures. Transcriptomic and metabolomic data revealed at feature-, systems- and integrative- level biologically relevant processes involved during CPT, e.g. lipid metabolism and stress response.

Conclusion
Multi-omics strategies have a great potential in pain research, both at feature- and systems- level. Therefore, they should be exploited in intervention studies, such as pain provocation tests, to gain knowledge on the biological mechanisms involved in complex traits.
