ObjectivesThis study aimed to explore the relationship (presence and severity) between chronic breathlessness and sleep problems, independently of diagnoses and health service contact by surveying a large, representative sample of the general population.SettingAnalysis of the 2017 South Australian Health Omnibus Survey, an annual, cross-sectional, face-to-face, multistage, clustered area systematic sampling survey carried out in Spring 2017.Chronic breathlessness was self-reported using the ordinal modified Medical Research Council (mMRC; scores 0 (none) to 4 (housebound)) where breathlessness has been present for more than 3 of the previous 6 months. ‘Sleep problems—ever’ and ‘sleep problem—current’ were assessed dichotomously. Regression models were adjusted for age; sex and body mass index (BMI).Results2900 responses were available (mean age 48.2 years (SD=18.6); 51% were female; mean BMI 27. 1 (SD=5.9)). Prevalence was: 2.7% (n=78) sleep problems—past; 6.8% (n=198) sleep problems—current and breathlessness (mMRC 1–4) was 8.8% (n=254). Respondents with sleep problemspast were more likely to be breathless, older with a higher BMI and sleep problems—present also included a higher likelihood of being female.After adjusting for age, sex and BMI, respondents with chronic breathlessness had 1.9 (95% CI=1.0 to 3.5) times the odds of sleep problems—past and sleep problems—current (adjusted OR=2.3; 95% CI=1.6 to 3.3).ConclusionsThere is a strong association between the two prevalent conditions. Future work will seek to understand if there is a causal relationship using validated sleep assessment tools and whether better managing one condition improves the other.

Published: August 2021

IntroductionLimited data from controlled clinical trials are available for men who experience biochemical recurrence after definitive therapy for prostate cancer. In the absence of overt metastases, patients with non-metastatic castration-sensitive prostate cancer (nmCSPC) often receive androgen deprivation therapy (ADT). There is no standard-of-care consensus on optimal ADT timing, although most men are treated prior to metastases, especially those with high-risk features (Gleason score 8–10 or prostate-specific antigen doubling time (PSADT) <9–12 months). Given data that ADT plus novel hormonal agents improve survival in men with metastatic CSPC, there is a desire to evaluate these agents earlier in the disease course. The main objective of EMBARK is the comparative assessment of enzalutamide plus leuprolide (luteinising hormone-releasing hormone agonist (LHRHa)) or enzalutamide monotherapy versus monotherapy LHRHa to improve metastasis-free survival (MFS) in patients with high-risk nmCSPC PSA recurrence after definitive therapy.Methods and analysisEMBARK is a randomised, phase 3 study of high-risk patients with nmCSPC, a PSADT of ≤9 months and a screening PSA of ≥2 ng/mL above the nadir after radiotherapy (RT) or ≥1 ng/mL after radical prostatectomy (RP) with or without postoperative RT. Men (n=1050) are randomised 1:1:1 to enzalutamide 160 mg/day plus LHRHa or placebo plus LHRHa (double-blind arms) or enzalutamide monotherapy (open-label arm). Treatment is suspended at week 37 if PSA concentrations are <0.2 ng/mL and reinstated if levels rise to ≥2.0 ng/mL with RP or ≥5.0 ng/mL without RP. Patients with PSA ≥0.2 ng/mL at week 37 continue until treatment discontinuation criteria are met. The primary endpoint is MFS comparing enzalutamide plus LHRHa versus placebo plus LHRHa.Ethics and disseminationThe study is conducted under the guiding principles of the World Medical Association Declaration of Helsinki. The results will be disseminated at research conferences and in peer-reviewed journals.Trial registration numberNCT02319837.

ObjectivesTo examine the rate and characteristics of hospitalisation in the last month of life and place of death among nursing home residents and to identify related care processes, facility factors and residents’ characteristics.SettingA cross-sectional study (2015) of deceased residents in 322 nursing homes in six European countries.ParticipantsThe nursing home manager (N=1634), physician (N=1132) and primary nurse (N=1384) completed questionnaires.Outcome measuresHospitalisation and place of death were analysed using generalised linear and logistic mixed models. Multivariate analyses were conducted to determine associated factors.ResultsTwelve to 26% of residents were hospitalised in the last month of life, up to 19% died in-hospital (p<0.001). Belgian residents were more likely to be hospitalised than those in Italy, the Netherlands and Poland. For those dying in-hospital, the main reason for admission was acute change in health status. Residents with a better functional status were more likely to be hospitalised or to die in-hospital. The likelihood of hospitalisation and in-hospital death increased if no conversation on preferred care with a relative was held. Not having an advance directive regarding hospitalisations increased the likelihood of hospitalisation.ConclusionsAlthough participating countries vary in hospitalisation and in-hospital death rates, between 12% (Italy) and 26% (Belgium) of nursing home residents were hospitalised in the last month of life. Close monitoring of acute changes in health status and adequate equipment seem critical to avoiding unnecessary hospitalisations. Strategies to increase discussion of preferences need to be developed. Our findings can be used by policy-makers at governmental and nursing home level.

ObjectivesTo design, deliver and evaluate a programme of training workshops for biomedical researchers aimed at building confidence and skills in actively involving patients and the public (PPI) in research.DesignA bespoke programme of training workshops in PPI aimed at researchers.SettingA large National Institute for Health Research Biomedical Research Centre in London and several partner organisations.Participants721 scientists, clinicians and research managers attending dedicated training in PPI at a major London NHS (National Health Service)–university partnership.InterventionsA programme of 72 training workshops, designed to build practical skills and confidence for researchers working with patients and the public in research, was delivered at a major research-active NHS:university partnership. An iterative approach was taken to the programme, with the content of the workshops continually reviewed and refreshed to respond to the needs of researchers. Surveys before, immediately following and 6 months after training investigated the impact on researchers’ confidence and skills in PPI work, and the kind of PPI they subsequently carried out.ResultsTraining brought about immediate marked increases in researchers’ self-reported confidence to carry out PPI activities within their research, and in their knowledge of good practice. The evaluation indicates that workshop attendees were more likely to involve patients in their research following training. Researchers tended to involve patients and the public in a range of areas, including input to study design and patient information, in particular.ConclusionsWhen positioned within a broader organisational strategy for PPI in research, such training has an important role to play in progressing PPI in a major research partnership. Training appeared to provide the confidence needed to carry out PPI which enabled further development of confidence and skills. Involving researchers who have attended the training in the ongoing development of the programme and bringing in patients to the training programme are key next steps.

Published: August 2021

ObjectivesThis systematic review summarises the evidence on the correlation between recurrent acute otitis media (rAOM) or chronic suppurative otitis media (CSOM) and sensorineural hearing loss (SNHL).Research methodsPubMed, Embase and Cochrane Library databases were searched from inception to 15 January 2021. Two authors independently identified articles, extracted data and performed quality assessment for included studies. Studies comparing the sensorineural hearing levels of patients with a history of rAOM/CSOM for >3 months to a control group were included.ResultsScreening of 4168 articles lead to inclusion of two case-control studies (control-group: patients non-OM) and seven cohort-studies (control group: contralateral ear). Quality assessment indicated considerable risk of bias in all studies. Reported populations varied (sample size 13–607, mean age 22–41.5 years, mean duration of disease 6.1–12.4 years). The OR for SNHL in the OM-group was 3.30–7.86 (95% CI 1.16 to 9.40, p<0.05) in cohort studies (n=2), and 0.05 (95% CI 0 to 0.78, p<0.05) in a case-control study. Mean/median bone conduction thresholds were respectively 1.19–32.21/0–10 dB higher on all frequencies (0.5–4 kHz) for the OM-group in four cohort studies (p<0.05). Two other studies reported no statistical test outcomes.ConclusionDue to the high risk of bias of included studies, effect estimates heterogeneity and suboptimal research designs, no conclusion on the correlation between OM and SNHL can be made. It emphasises the need for future prognostic studies.

ObjectiveTo determine the prevalence and sociodemographic factors associated with active commuting and leisure-time physical activity (LTPA) among adults in western Nepal.DesignCross-sectional study.SettingAdults from semiurban areas in western Nepal.Participants2815 adults aged 25–65 years who participated in the ‘Community-Based Management of Hypertension in Nepal (COBIN)’ Study. Multiple logistic regression analysis was used to identify the sociodemographic factors associated with active commuting and LTPA.OutcomeSelf-reported participation in active commuting and LTPA.ResultsMost study participants (96%) commuted actively (walked or cycled) from one place to another. Our results showed that only a small proportion (3.7%) of participants engaged in moderate or vigorous LTPA. Compared with those in paid employment, the odds of commuting actively were higher among people working in agriculture or as labourers (OR: 4.57, 95% CI: 2.46 to 8.48), those retired/unemployed (OR: 2.98, 95% CI: 1.42 to 6.25) and those in unpaid employment (OR: 1.85, 95% CI: 1.06 to 3.22). Adults who were overweight or had obesity were less likely to commute actively. Compared with adults aged 25–34 years, older adults were less likely (OR: 0.35, 95% CI: 0.17 to 0.72) to engage in LTPA. Women were 0.46 times less likely to engage in LTPA compared with men.ConclusionMost adults engaged in active commuting for work or travel. Less than 5% participated in any form of moderate or vigorous LTPA. Longitudinal studies incorporating objective assessment of physical activity and a range of individual, interpersonal, and environmental factors will help understand how to promote active commuting and LTPA among Nepalese adults.Trial registration number: ClinicalTrials.govNCT02428075.

Authors: Mochizuki Takeshi , Yano Koichiro , Ikari Katsunori , Okazaki Ken 
Published: August 2021

Background: To compare the efficacy of intra-articular injection (IA) with 10 mg and 20 mg triamcinolone for treatment of rheumatoid arthritis (RA) of the wrist joint. Methods: We enrolled 20 patients with swelling and pain in wrist due to RA in the present prospective, randomized, pilot study. Patients were randomly assigned in a 1:1 ratio to either the 20 mg or 10 mg group, and received IA of the appropriate dose of triamcinolone. Efficacy was assessed by recording Numerical Rating Scale (NRS) for pain and improvement in power doppler (PD) scale score at weeks 1, 4, and 12 of treatment compared with baseline. The shortened Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH) was recorded at baseline and week 12. Results: The NRS was found to be significantly improved at weeks 4 (p = 0.006) and 12 (p = 0.036) among the total study population. Neither the change in NRS nor the improvement PD scale score from baseline were significantly different between the two groups at any week (NRS: week 1, p = 0.617; week 4, p = 0.727; and week 12, p = 0.878; PD scale score: week 1, p = 0.370; week 4, p = 1.000; and week 12, p = 0.179). Among the entire study population, the QuickDASH was not significantly improved at week 12 nor was the change from baseline significantly different between the two groups at week 12 (p = 0.592). Conclusions: IA of triamcinolone was effective for pain relief in context of RA in the wrist joint. However, in terms of NRS, improvement of PD scale score, and QuickDASH score, the efficacies of 10 mg and 20 mg triamcinolone were not significantly different. Thus, IA of 10 mg triamcinolone may be sufficient for the treatment of RA in the wrist joint.

Authors: Shin Seung-Han , Cho Joonhyung , Lee Ji-Won , Chung Yang-Guk 
Published: August 2021

Background: Dorsal rotation or persistent displacement of the fracture fragment is frequently encountered in extension block pinning for mallet fractures. We reviewed nine irreducible mallet fracture patients treated with mini-open reduction and extension block pinning. Methods: A small V-shaped incision was made on the fracture gap when there was persistent displacement of fracture fragment despite closed maneuvers and percutaneous procedures while performing extension block pinning. Soft tissue or granulation tissue hampering reduction was removed through the incision. Anatomical reduction was guided with a freer elevator. The incision was closed by distal interphalangeal joint transfixation in extension without any suture. Pin tips were buried under the skin. The incision and pin entry sites were covered with skin adhesive, and the patients were allowed to wash their hands 1–2 days after the surgery. No splint was applied postoperatively. Mean follow-up period was 13 months. Results: Anatomical reduction was achieved in 7 out of 9 patients. In the rest 2 patients, postoperative step-off of the articular surface at the fracture site was less than 0.5 mm. Solid union was achieved in all cases. The mean extension lag at final follow-up was 0°. No patient developed postoperative external bleeding or other complications in the incision site or the pin site. Conclusions: Mini-open reduction and extension block pinning appears to be a good option for irreducible mallet fractures, which improves reduction quality and patients’ convenience.
Semantic Graphical Dependence Parsing Model in Improving English Teaching Abilities

Published: August 2021

It is a very difficult problem to achieve high-order functionality for graphical dependency parsing without growing decoding difficulties. To solve this problem, this article offers a way for Semantic Graphical Dependence Parsing Model (SGDPM) with a language-dependency model and a beam search to represent high-order functions for computer applications. The first approach is to scan a large amount of unnoticed data using a baseline parser. It will build auto-parsed data to create the Language-dependence Model (LDM). The LDM is based on a set of new features during beam search decoding, where it will incorporate the LDM features into the parsing model and utilize the features in parsing models of bilingual text. Our approach has main benefits, which include rich high-order features that are described given the large size and the additional large crude corpus for increasing the difficulty of decoding. Further, SGDPM has been evaluated using the suggested method for parsing tasks of mono-parsing text and bi-parsing text to carry out experiments on the English and Chinese data in the mono-parsing text function using computer applications. Experimental results show that the most accurate Chinese data is obtained with the best known English data systems and their comparable accuracy. Furthermore, the lab-scale experiments on the Chinese/General bilingual information in the bitext parsing process outperform the best recorded existing solutions.

Abstract

Collagen remodeling contributes to many physiologic and pathologic processes. In primary tumors, the linearization of collagen fibers promotes cancer cell invasion and metastasis and is indicative of poor prognosis. However, it remains unknown whether there are endogenous inhibitors of collagen linearization that could be exploited therapeutically. Here, we show that collagen linearization is controlled by two secreted matricellular proteins with antagonistic functions. Specifically, WISP1 was secreted by cancer cells, bound to type I collagen (Col I), and linearized Col I via its cysteine-rich C-terminal (CT) domain. In contrast, WISP2, which lacks a CT domain, inhibited Col I linearization by preventing WISP1-Col I binding. Analysis of patient data revealed that WISP2 expression is lower in most solid tumors, in comparison with normal tissues. Consequently, genetic or pharmacologic restoration of higher WISP2 levels impaired collagen linearization and prevented tumor cell invasion and metastasis in vivo in models of human and murine breast cancer. Thus, this study uncovers WISP2 as the first inhibitor of collagen linearization ever identified and reveals that collagen architecture can be normalized and metastasis inhibited by therapeutically restoring a high WISP2:WISP1 ratio.

Significance:
Two secreted factors, WISP1 and WISP2, antagonistically regulate collagen linearization, and therapeutically increasing the WISP2:WISP1 ratio in tumors limits collagen linearization and inhibits metastasis.

Abstract

Although patients with advanced ovarian cancer may respond initially to treatment, disease relapse is common, and nearly 50% of patients do not survive beyond five years, indicating an urgent need for improved therapies. To identify new therapeutic targets, we performed single-cell and nuclear RNA-seq data set analyses on 17 human ovarian cancer specimens, revealing the oncostatin M receptor (OSMR) as highly expressed in ovarian cancer cells. Conversely, oncostatin M (OSM), the ligand of OSMR, was highly expressed by tumor-associated macrophages and promoted proliferation and metastasis in cancer cells. Ovarian cancer cell lines and additional patient samples also exhibited elevated levels of OSMR when compared with other cell types in the tumor microenvironment or to normal ovarian tissue samples. OSMR was found to be important for ovarian cancer cell proliferation and migration. Binding of OSM to OSMR caused OSMR–IL6ST dimerization, which is required to produce oncogenic signaling cues for prolonged STAT3 activation. Human monoclonal antibody clones B14 and B21 directed to the extracellular domain of OSMR abrogated OSM-induced OSMR–IL6ST heterodimerization, promoted the internalization and degradation of OSMR, and effectively blocked OSMR-mediated signaling in vitro. Importantly, these antibody clones inhibited the growth of ovarian cancer cells in vitro and in vivo by suppressing oncogenic signaling through OSMR and STAT3 activation. Collectively, this study provides a proof of principle that anti-OSMR antibody can mediate disruption of OSM-induced OSMR–IL6ST dimerization and oncogenic signaling, thus documenting the preclinical therapeutic efficacy of human OSMR antagonist antibodies for immunotherapy in ovarian cancer.

Significance:
This study uncovers a role for OSMR in promoting ovarian cancer cell proliferation and metastasis by activating STAT3 signaling and demonstrates the preclinical efficacy of antibody-based OSMR targeting for ovarian cancer treatment.
