Published: February 2023

Abstract
Background
Direct-to-consumer telemedicine (TM), with patients having access to a physician via video or text chat, has gradually been introduced into Swedish primary care during the last two decades. Earlier studies have concluded that patients were generally satisfied with TM and the satisfaction rate was consistently above 80% and comparable with in-person visits. Despite the number of studies looking at user experience, studies assessing what factors influence patient satisfaction are lacking. To further develop digital care, it is important to explore the patients’ opinions of this relatively new phenomenon. The primary aim of this study was to explore patient opinions regarding satisfaction with TM-provided care, based on different age groups, sex, symptoms, and which type of health care professional they were assessed by.

Methods
The study was a quantitative web survey performed in 2020–2021 in which 688 patients using a TM provider in Southern Sweden responded. The results were analysed using Chi-2 test with the main outputs; satisfaction level and percentage that would use TM for similar symptoms in the future.

Results
The results from the survey population show that patients that were assessed by a doctor were more likely to intend to use TM in the future and were more satisfied with the visit than patients assessed by a nurse. Our results also show that patients older than 70 years of age were less likely to use TM again compared to the total population.

Conclusion
This study shows that patient satisfaction with TM varied depending on the patient’s age. The older patients were less satisfied than their younger equivalents. For patient satisfaction to be high, it was also crucial which health care provider the patient had been assessed by. The patients were more satisfied when assessed by a doctor than by a nurse. In addition, the study shows that patient satisfaction with TM was generally comparable to traditional care.

Abstract
Background
The renal risk score (RRS) is a useful tool to predict end-stage renal disease (ESRD) in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). The current study aimed to validate the predictive performance of RRS and to further modify this model in Chinese AAV patients.

Methods
Two hundred and seventy-two patients diagnosed with AAV confirmed by renal biopsies were retrospectively enrolled from a single center. The RRS was calculated based on 3 categorical variables, i.e., the proportion of normal glomeruli, the proportion of interstitial fibrosis and tubular atrophy (IF/TA), and eGFR at biopsy, classifying these patients into low-, medium-, and high-risk groups. In addition, a modified model was developed based on the RRS and was further validated in another independent cohort of 117 AAV patients. The predictive performance of each model was evaluated according to discrimination and calibration.

Results
Patients were classified by the RRS into low- (26.5%), medium- (46.7%), and high-risk (26.8%) groups, with 120-month renal survival rates of 93.3%, 57.2%, and 18.4%, respectively (P < 0.001). The RRS showed good discrimination but less satisfactory calibration. Therefore, a modified model with improved discrimination and calibration was developed in Chinese AAV patients, with eGFR, proportion of normal glomeruli (both as continuous variables), and IF/TA (< 25%, 25–50%, > 50%) included. Internal and external validation of the modified model were performed. Finally, an online risk prediction tool was developed based on the modified model.

Conclusions
The RRS was an independent predictor of ESRD of AAV patients. The modified model could predict the probability of ESRD for AAV patients with improved performance in Chinese AAV patients.
Multiscale reconstruction of bronchus and cancer cells in human lung adenocarcinoma
Authors: Li Xin , Zhang Bowen , Liang Yanmei , Li Ting 
Published: February 2023

Abstract
Background
While previous studies primarily focused on the structure of the normal whole mouse lung, the whole bronchus and cytoarchitectural details of the mouse intact lung lobe have been discovered at single-cell resolution. Revealing the sophisticated lung adenocarcinoma structure at three-dimensional (3D) and single-cell level remains a fundamental and critical challenge for the pathological mechanism research of lung adenocarcinoma (LA).

Methods
Fluorescence micro-optical Sectioning Tomography (fMOST) combined with PI staining were used to obtain the 3D imaging of the human LA tissue at single-cell resolution.

Results
With a spatial resolution of 0.32 × 0.32 × 1.0 μm3, the dataset of human LA with single-cell precision consists of two channels, each of which contains information about the bronchi and the cytoarchitecture. The bronchial wall is thicker and the lumen is smaller in the cancer tissue, in which its original normal structure is vanished. More solid components, more clustered cancer cells with larger nucleoli, and more significant atypia are found in cancer tissue. In paracancerous tissue, the bronchial wall cells have a monolayer or bilayer structure, cluster along the wall, and are relatively dispersed. Few fibrous structures and occasional dissemination of spread through air spaces (STAS) are observed.

Conclusions
Based on the human LA tissue dataset obtained by fMOST and PI staining, the bronchi and cells were reconstructed and visualized. This work provides a technical roadmap for studying the bronchus and cytoarchitectural structure and their spatial relationship in LA tissue, which may help with the understanding of the main histological structure of LA among pathologists.

Published: February 2023

Abstract
Background
Toxoplasmosis is a zoonotic parasitic disease caused by Toxoplasma gondii. Toxoplasma gondii infection of the lungs can lead to severe pneumonia. However, few studies have reported Toxoplasma pneumonia. Most reports were clinical cases due to the lack of a good disease model. Therefore, the molecular mechanisms, development, and pathological damage of Toxoplasma pneumonia remain unclear.

Methods
A mouse model of Toxoplasma pneumonia was established by nasal infection with T. gondii. The model was evaluated using survival statistics, lung morphological observation, and lung pathology examination by hematoxylin and eosin (H&E) and Evans blue staining at 5 days post-infection (dpi). Total RNA was extracted from the lung tissues of C57BL/6 mice infected with T. gondii RH and TGME49 strains at 5 dpi. Total RNA was subjected to transcriptome analysis by RNA sequencing (RNA-seq) followed by quantitative real-time polymerase chain reaction (qRT–PCR) validation. Transcript enrichment analysis was performed using the Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases to assess the biological relevance of differentially expressed transcripts (DETs).

Results
C57BL/6 mice infected with T. gondii via nasal delivery exhibited weight loss, ruffled fur, and respiratory crackles at 5 dpi. The clinical manifestations and lethality of RH strains were more evident than those of TGME49. H&E staining of lung tissue sections from mice infected with T. gondii at 5 dpi showed severe lymphocytic infiltration, pulmonary edema, and typical symptoms of pneumonia. We identified 3167 DETs and 1880 DETs in mice infected with the T. gondii RH and TGME49 strains, respectively, compared with the phosphate-buffered saline (PBS) control group at 5 dpi. GO and KEGG enrichment analyses of DETs showed that they were associated with the immune system and microbial infections. The innate immune, inflammatory signaling, cytokine-mediated signaling, and chemokine signaling pathways displayed high gene enrichment.

Conclusion
In this study, we developed a new mouse model for Toxoplasma pneumonia. Transcriptome analysis helped to better understand the molecular mechanisms of the disease. These results provided DETs during acute T. gondii lung infection, which expanded our knowledge of host immune defenses and the pathogenesis of Toxoplasma pneumonia.

Published: February 2023

Abstract
Background
The parthenogenic reproductive ability of Haemaphysalislongicornis, facilitating quick life cycle completion and rapid geographic spread and its pathogen vector potential make infestations a risk to human and canine health. Two 90-day studies were initiated to evaluate the efficacy of a single fluralaner administration for the treatment and prevention of H.longicornis infestations on dogs.

Methods
Dogs were randomly assigned (10 dogs/group) to either an untreated control group or a group treated once (Day 0) with 13.64% w/w fluralaner chewable tablets (Bravecto®) at the minimum label dose rate of 25 mg/kg. Each dog was infested with approximately 50 H.longicornis ticks on Days -9 or -6 and on Days -2, 28, 58 and 88. A different US tick isolate was used in each study. Tick counts were completed on Days -7 or -4, 2, 30, 60 and 90. The primary efficacy criterion was a 90% reduction in arithmetic mean tick counts between the treated and control groups. For between-group comparisons at any assessment, at least six control dogs were required to retain at least 25% of the infestation dose (13 live ticks).

Results
Pre-study infestations demonstrated susceptibility of all study dogs to challenge with H.longicornis. At each subsequent assessment in both studies, at least seven untreated control dogs retained ≥ 25% of the challenge, demonstrating adequate infestations for each efficacy calculation. On Days 2, 30, 60 and 90 the mean live tick infestation rate (number of ticks recovered from each dog/infesting challenge of each dog) of untreated control dogs ranged from 27.8 to 60.8%. No live ticks, free or attached, were found on any fluralaner-treated dog in either study. Between-group differences were statistically significant (P ≤ 0.0002) at each assessment.

Conclusion
At the minimum recommended label dose rate of 25 mg/kg, fluralaner chewable tablets were 100% effective in eliminating H.longicornis ticks from dogs infested at the time of treatment. Complete efficacy against both US isolates of this tick was maintained through 90 days following a single treatment. Therefore, fluralaner is a treatment of choice for protecting dogs against this invasive tick species.

The effects of exercise therapy feedback on subjective treatment outcome and patient satisfaction: study protocol for a mono-centric, randomized, controlled trial in orthopedic rehabilitation (FeedYou)
Authors: Schuber André Arik , Schmidt Sebastian , Hombach Sarah , Schaller Andrea 
Published: February 2023

Abstract
Background
The disease burden of musculoskeletal disorders necessitates multidisciplinary and patient-centered models of care. Exercise therapy represents a first-line treatment strategy and a central component of medical rehabilitation. In order to realize the goals of long-term physical activity and participation as proposed by the ICF, exercise therapy can be supplemented by interventional techniques from the field of psychotherapy. Although psychotherapist feedback has been shown to improve therapeutic outcome and patient satisfaction, feedback use in exercise therapy is mostly limited to motor learning and exercise instruction. The present paper therefore describes the use of multidimensional exercise therapy feedback in medical rehabilitation. The aims of the trial presented in this study protocol are to evaluate the effects of this novel feedback approach on rehabilitation outcomes in comparison to usual care.

Methods
The study is designed as a prospective, mono-centric, randomized controlled, superiority trial (RCT) with two parallel groups and three measuring points: T0 = start of three-week inpatient rehabilitation, T1 = end of three-week inpatient rehabilitation, T2 = 12-week follow-up. In total, 132 patients suffering from chronic neck, shoulder and/or lumbar spine disorders will be recruited. The intervention involves multidimensional exercise therapy feedbacks during the initial and final physical therapist examination, as well as short exercise therapy feedbacks during the course units of the mandatory group-based exercise therapy program. Primary outcomes are the subjective treatment outcome, assessed by BPI and indication-specific questionnaires, as well as patient satisfaction, assessed by ZUF-8 and an intervention-specific questionnaire. The final data collection is expected by May 2023.

Discussion
This study may provide a valuable insight into the effectiveness of multidimensional exercise therapy feedback to improve treatment outcomes and patient satisfaction in medical rehabilitation. This could contribute to rehabilitation quality assurance and the long-term physical activity behavior of rehabilitation patients.
Trial registration The trial has been registered with the German Clinical Trial Register (DRKS) under the Registration Number DRKS00027263.
Concurrence of immune thrombocytopenic purpura and thrombotic thrombocytopenic purpura: a case report and review of the literature
Authors: Lin Hung-Chen , Huang Jinxiang , Huang Jing , Zhang Li-Jun , Yin Xiao-Wu , Yang Jian-Cheng , Huang Xiao-Yan 
Published: February 2023

Abstract
Background
Immune thrombocytopenic purpura and thrombotic thrombocytopenic purpura are both causes of thrombocytopenia. Recognizing thrombotic thrombocytopenic purpura is crucial for subsequent treatment and prognosis. In clinical practice, corticosteroids and rituximab can be used to treat both immune thrombocytopenic purpura and thrombotic thrombocytopenic purpura; plasma exchange therapy is the first-line treatment in thrombotic thrombocytopenic purpura, while corticosteroids are strongly recommended as first-line treatment in immune thrombocytopenic purpura. The differential diagnosis of immune thrombocytopenic purpura and thrombotic thrombocytopenic purpura is essential in clinical practice. However, case reports have suggested that immune thrombocytopenic purpura and thrombotic thrombocytopenic purpura can occur concurrently.

Case presentation
We report the case of a 32-year-old Asian female without previous disease who presented with pancytopenia, concurrent with immune thrombocytopenic purpura and thrombotic thrombocytopenic purpura. The morphology of the megakaryocytes in the bone marrow indicated immune-mediated thrombocytopenia. The patient received glucocorticoid treatment, and her platelet count increased; however, schistocytes remained high during the course of the therapy. Further investigations revealed ADAMTS13 activity deficiency and positive ADAMTS13 antibodies. The high titer of antinuclear antibody and positive anti-U1-ribonucleoprotein/Smith antibody indicated a potential autoimmune disease. However, the patient did not fulfill the current criteria for systemic lupus erythematosus or mixed connective tissue disease. The patient responded well to plasma exchange therapy, and her platelet count remained normal on further follow-up.

Conclusions
Concurrence of immune thrombocytopenic purpura and thrombotic thrombocytopenic purpura is rare, but clinicians should be aware of this entity to ensure prompt medical intervention. Most of the reported cases involve young women. Human immunodeficiency virus infection, pregnancy, and autoimmune disease are the most common underlying conditions.

Abstract
Background
Recently, we reported that tamoxifen-resistant (TAM-R) breast cancer cells are cross-resistant to irradiation. Here, we investigated the mechanisms associated with tamoxifen-induced radioresistance, aiming to prevent or reverse resistance and improve breast cancer treatment.

Methods
Wild-type ERα-positive MCF7 and ERα-negative MDA-MB-231 breast cancer cells and their TAM-R counterparts were analyzed for cellular metabolism using the Seahorse metabolic analyzer. Real-time ROS production, toxicity, and antioxidant capacity in response to H2O2, tamoxifen, and irradiation were determined. Tumor material from 28 breast cancer patients before and after short-term presurgical tamoxifen (ClinicalTrials.gov Identifier: NCT00738777, August 19, 2008) and cellular material was analyzed for NRF2 gene expression and immunohistochemistry. Re-sensitization of TAM-R cells to irradiation was established using pharmacological inhibition.

Results
TAM-R cells exhibited decreased oxygen consumption and increased glycolysis, suggesting mitochondrial dysfunction. However, this did not explain radioresistance, as cells without mitochondria (Rho-0) were actually more radiosensitive. Real-time measurement of ROS after tamoxifen and H2O2 exposure indicated lower ROS levels and toxicity in TAM-R cells. Consistently, higher antioxidant levels were found in TAM-R cells, providing protection from irradiation-induced ROS. NRF2, a main activator of the antioxidant response, was increased in TAM-R cells and in tumor tissue of patients treated with short-term presurgical tamoxifen. NRF2 inhibition re-sensitized TAM-R cells to irradiation.

Conclusion
Mechanisms underlying tamoxifen-induced radioresistance are linked to cellular adaptations to persistently increased ROS levels, leading to cells with chronically upregulated antioxidant capacity and glycolysis. Pharmacological inhibition of antioxidant responses re-sensitizes breast cancer cells to irradiation.

Published: February 2023

Background Knowledge dissemination is paramount so physicians may practice the most up-to-date, evidence-based medicine to best serve their patients. Medical conferences are a commonly employed method of facilitating this. By determining the publication rate of research presented at a conference, the quality of the conference is indirectly assessed. Therefore, this study aimed to determine the publication rate, along with other conference metrics, of abstracts presented at the Canadian Society of Otolaryngology-Head and Neck Surgery (CSOHNS) meetings from 2008 to 2018. Methods All abstracts presented at the CSOHNS Annual Meetings from 2008 to 2018 were reviewed from publicly available records. Presentation year, presentation type (i.e. oral or poster), whether each abstract was presented in the Poliquin Resident Research Competition, and the country in which the lead author's institution was located, were collected. Publication status of each abstract was then determined using a six-tiered search strategy in PubMed and Google Scholar. All data were then analyzed using SPSS Version 27.0. Results From 2008 to 2018, 1947 abstracts were analyzed, yielding an overall publication rate of 58.7%. There was a significantly increasing trend in publication rate over the 11 years (p = 0.015). The rate of publication differed based on type of presentation (oral 65.1%, poster 50.2%; p = 0.001). Most presentations were presented by a first author associated with a Canadian institution (94.4%). The top journal in which research was published was Journal of Otolaryngology- Head and Neck Surgery (37.3%). The mean impact factor of the journals in which presentations were published was 2.92. Finally, the median time to publication was 14 months (IQR: 9.0–25.0). Conclusions Research presented at 2008–2018 CSOHNS annual meetings was published in academic journals at higher rates than research at comparable conferences. Oral presentations have a significantly greater publication rate, compared to poster presentations. Additionally, the upward trend in publication rate over the 11 meetings suggests a steady increase in the quality of research being presented. Graphical Abstract

Published: February 2023

Abstract
Background
Giant cell arteritis (GCA) is the most common primary systemic vasculitis in people 50 years of age and over, and it is considered a medical emergency due to the potential risk of permanent visual loss. Color Doppler ultrasound (CDU) of the temporal arteries is a rapid, noninvasive method to diagnose GCA. This study aims to determine the diagnostic accuracy of the halo sign in temporal arteries by CDU in people with suspected GCA.

Methods
The systematic literature review included the search for publications in the following electronic databases: PubMed, Embase, CENTRAL, LILACS, WHO ICTRP, ClinicalTrials.gov, gray literature up to December 2022, and no date or language restrictions were applied. We analyzed studies including patients over 50 years of age with suspected GCA evaluating CDU of temporal arteries as a diagnostic tool against clinical diagnosis as a standard reference. Paper titles and abstracts were selected by two investigators independently for all available records. The quality of the studies was assessed using the Quality of Diagnostic Accuracy Studies tool (QUADAS-2) and the R software (version 4.2.1) was used for data analysis. The protocol of this review is registered with PROSPERO (CRD42016033079).

Results
Twenty-two studies including 2893 participants with suspected GCA who underwent temporal artery CDU were evaluated. The primary analysis results showed a sensitivity of 0.76 [95% confidence interval (95 CI) 0.69–0.81] and specificity of 0.93 (95 CI 0.89–0.95) when the halo sign was compared to clinical diagnosis. The sensitivity value of 0.84 (95 CI 0.72–0.92) and specificity of 0.95 (95 CI 0.88–0.98) were found in five studies involving 1037 participants that analyzed the halo sign and temporal artery compression sign. A sensitivity of 0.86 (95 CI 0.78–0.91) and specificity of 0.95 (95 CI 0.89–0.98) were found in four studies with 603 participants where the halo sign was evaluated CDU on temporal and axillary arteries.

Conclusion
The detection of the halo sign by CDU of temporal arteries has good accuracy for the diagnosis of cranial GCA. The compression sign in temporal arteries and the addition of axillary arteries assessment improves the diagnostic performance of CDU for GCA.
