Authors: Ceyhan Yasemin , Soylu Dilek 
Published: October 2023

The study aimed to examine the moderator effect of organ transplant waiting time on hopelessness and death anxiety. The study was conducted in a descriptive and correlational design with 378 patients on the transplant waiting list (Agust 2021- March 2022). Multiple linear regression and PROCESS macro-Model 1 were used in the analyses. In this study, the STROBE checklist was followed. According to the results of the regression analysis, waiting for a transplant for 6–10 years reduced death anxiety by 9.38 times and waiting for a transplant for 16–20 years increased death anxiety by 31.3 times. The predictors in the regression analysis explained 33% of the model. The moderator effect constituted 6.4% of the explained part of the model, which was 25.4%; the R2 change was 3.4% and significant. We found that the longer the waiting period for organ transplant recipients, the higher the hopelessness and death anxiety.

The development of novel nanomaterials with superior reflection loss (RL), thin thickness, wide bandwidth, and low density has recently received significant attention in an effort to increase their effectiveness in electromagnetic (EM) microwave absorption while maintaining an easy manufacturing process. Naturally, using conventional materials with magnetic or dielectric loss makes it difficult to achieve the last criterion and limitations the thickness of the absorber and mass production. In this work, microwave nanocomposites samples were prepared on epoxy resin with different percentages of the nanoparticles of aluminum oxide (epoxy/Al2O3) with surfaces treated by amino propyl and silane. The surface treatment was carried out to improve the adhesion, morphology, and EM properties of the samples to enhance the microwave absorption and the Shielding Effectiveness (SE). Therefore, the treated sample can be considered as potential candidate for high frequency EM absorption applications. Then, the study is followed by structural, morphological, thermal, and electrical characterization of the prepared samples in order to enhance the performances of the latters. The EM absorption and the shielding effectiveness were done in the X band frequency (8 GHz-12 GHz). The obtained results confirmed that the nanocomposites treated samples exhibit higher EM absorption performance and better electrical characteristics. Overall, these results put forward the role played by the addition of the nanoparticles films as high-performance materials in electronic devices and EM applications.

Purpose To report a case of inadvertent cystic filtering bleb in a patient with scleral fixated intraocular lens (SFIOL) implantation 7 years after initial procedure. Case presentation A 14-year-old boy underwent lensectomy, vitrectomy and a sutured rigid SFIOL for microspherophakia in the right eye. Seven years later, the patient presented with hypotony related ocular changes. Examination revealed an inadvertent cystic filtering bleb at the scleral section. Anterior segment optical coherence tomography (ASOCT) revealed gap in inner lips of the scleral wound, bridged by a thin strip of scleral tissue. A conservative management with bandage contact lens (BCL) failed after an initial improvement. Injection of trypan blue dye in the anterior chamber confirmed the presence and site of wound filtration. Surgical closure of the fistula was done and patient showed both structural and visual improvement. Conclusion Meticulous wound construction and water tight closure at the end of the surgery can avoid such complications. ASOCT can be helpful in diagnosing the area of fistula. A conservative management with BCL can help by tamponading the filtering bleb. However, in unresponsive cases, surgical closure of the fistula is recommended to improve the hypotony-related changes.

Published: October 2023

Background Children with autism spectrum disorders (ASD) struggle with impaired theory of mind. We aimed to evaluate the effect of remediation of theory of mind on theory of mind, face perception, and behavioral symptoms in children with ASD. Methods Thirty children with ASD were randomly assigned to two equal groups of theory of mind training and active control group. Attentive remediation of theory of mind (ARTOM) and story-telling sessions were used for intervention in the groups. Theory of mind and facial emotion recognition tests as well as Gilliam autism rating scale (GARS) were used for assessment in three baseline, post-intervention, and follow-up sessions. Repeated measures ANOVAs were used for analysis. Results The results showed improvement in facial emotion recognition and theory of mind in intervention group. The behavioral symptoms, measured by GARS, were ameliorated in the intervention group. The training effects lasted until follow-up session. Conclusions The results suggest remediation of basic components of theory of mind, without direct intervention on theory of mind, improves theory of mind skill. The results also suggest that the remediation of basic components of theory of mind improves social and communicational performance and ameliorates stereotypes symptoms in children with ASD.

Purpose: Access-related vascular complications in transfemoral transcatheter aortic valve implantation (TAVI) can be treated endovascularly or surgically. The aim of this study was to evaluate the short- and long-term outcomes of endovascular treatment compared with surgical repair for access-related vascular complications. Methods: This retrospective study was performed from January 1, 2018, to December 31, 2020. All transfemorally treated TAVI patients in whom a surgical or endovascular treatment for an access site complication was needed were included. The primary outcome was the need for any related vascular re-operation. Results: In total, 1219 transfemoral TAVI procedures were conducted during the study period. 19 patients suffered an access complication requiring endovascular treatment, while 54 patients required surgical repair. No differences were seen with regard to re-operations (endovascular 15.8% vs surgical 14.8%; p=0.919), wound infections (endovascular 0% vs surgical. 11.1%; p=0.129), and wound healing disorders (endovascular 15.8% vs surgical 29.6%; p=0.237). Patients undergoing endovascular treatment were discharged earlier (endovascular 11.2 vs surgical 14.9 days; p=0.028). After surgical repair, patients received significantly more blood transfusions than endovascularly treated patients (endovascular 1.00 vs surgical 3.1 red blood cell concentrate bags; p<0.001). No differences were found regarding the new onset of walking pain, rest pain, and ischemic ulcers during follow-up. Conclusion: In this retrospective cohort, endovascular treatment of access-related vascular complications of transfemoral TAVI procedures was safe and feasible. During the hospital stay, endovascularly treated patients received fewer blood transfusions and were discharged faster than surgically treated patients. No differences regarding clinical outcomes and re-intervention rates were seen during the follow-up. Clinical Impact Given the in this retrospective study demonstrated safety and feasibility of endovascular treatment for major access-related vascular complications, along with the in-hospital benefits and absence of follow-up disadvantages compared to surgical treatment, endovascular treatment should be considered in cases of major access-related vascular complications in transfemoral TAVI patients.

Purpose To evaluate the clinical characteristics and global trends in the surgical treatment of articular cartilage defects. Methods Studies in English published between January 1, 2001 and December 31, 2020 were retrieved from MEDLINE, WOS, INSPEC, SCIELO, KJD, and RSCI on the “Web of Science.” Patient data were extracted, including age, sex, defect location and laterality, duration of follow-up and symptoms, and body mass index (BMI). Data were further stratified according to the surgical method, lesion location, procedural type and geographical area, and time period. A comparative analysis was performed. Results Overall, 443 studies involving 26,854 patients (mean age, 35.25 years; men, 60.5%) were included. The mean lesion size and patient BMI were 3.51 cm2 and 25.61 kg/m2, respectively. Cartilage defects at the knees, talus, and hips affected 20,850 (77.64%), 3,983 (14.83%), and 1,425 (5.31%) patients, respectively. The numbers of patients who underwent autologous chondrocyte implantation, arthroscopic debridement/chondroplasty, osteochondral allograft (OCA), osteochondral autologous transplantation, and microfracture were 7,114 (26.49%), 5,056 (18.83%), 3,942 (14.68%), 3,766 (14.02%), and 2,835 (10.56%), respectively. European patients were the most numerous and youngest. North American patients had the largest defects. The number of patients increased from 305 in 2001 to 3,017 in 2020. In the last 5 years, the frequency of OCAs showed a greatly increasing trend. Conclusion Clinical characteristics and global trends in the surgical treatment of articular cartilage defects were revealed. The choice of operation should be based on the patient characteristics and defect location, size, and shape, as well as the patient’s preference.

BackgroundNovel biologic therapies have revolutionised the management of severe asthma with more ambitious treatment aims. Here we analyse the definition of clinical remission as a suggested treatment goal and consider the characteristics associated with clinical remission in a large, real-world severe asthma cohort.MethodsThis was a retrospective analysis of severe asthma patients registered in the UK Severe Asthma Registry (UKSAR) who met strict national access criteria for biologics. Patients had a pre-biologics baseline assessment and annual review. The primary definition of clinical remission applied included Asthma Control Questionnaire (ACQ)-5 <1.5 and no oral corticosteroids for disease control and forced expiratory volume in 1 s above lower limit of normal or no more than 100 mL less than baseline.Results18.3% of patients achieved the primary definition of remission. The adjusted odds of remission on biologic therapy were 7.44 (95% CI 1.73–31.95)-fold higher in patients with type 2 (T2)-high biomarkers. The adjusted odds of remission were lower in patients who were female (OR 0.61, 95% CI 0.45–0.93), obese (OR 0.49, 95% CI 0.24–0.65) or had ACQ-5 ≥1.5 (OR 0.19, 95% CI 0.12–0.31) pre-biologic therapy. The likelihood of remission reduced by 14% (95% CI 0.76–0.97) for every 10-year increase in disease duration. 12–21% of the cohort attained clinical remission depending on the definition applied; most of those who did not achieve remission failed to meet multiple criteria.Conclusions18.3% of patients achieved the primary definition of clinical remission. Remission was more likely in T2-high biomarker patients with shorter duration of disease and less comorbidity. Further research on the optimum time to commence biologics in severe asthma is required.

BackgroundOlder adults with asthma have the greatest burden and worst outcomes, and there is increasing evidence that chronic cough (CC) is associated with asthma severity and poor prognosis. However, the clinical characteristics of older adult patients with both asthma and CC remain largely unknown.MethodsParticipants with stable asthma underwent two cough assessments within 3 months to define the presence of CC. Patients were divided into four groups based on CC and age (cut-off ≥60 years). Multidimensional assessment was performed at baseline, followed by a 12-month follow-up to investigate asthma exacerbations. Logistic regression models were used to explore the interaction effect of CC and age on asthma control and exacerbations.ResultsIn total, 310 adult patients were prospectively recruited and divided into four groups: older CC group (n=46), older non-CC group (n=20), younger CC group (n=112) and younger non-CC group (n=132). Compared with the younger non-CC group, the older CC group had worse asthma control and quality of life and increased airflow obstruction. The older CC group showed an increase in moderate-to-severe exacerbations during the 12-month follow-up. There was a significant interaction effect of CC and ageing on the increased moderate-to-severe exacerbations (adjusted risk ratio 2.36, 95% CI 1.47–3.30).ConclusionOlder asthma patients with CC have worse clinical outcomes, including worse asthma control and quality of life, increased airway obstruction and more frequent moderate-to-severe exacerbations, which can be partly explained by the interaction between CC and ageing.
Designs for the simultaneous inference of concentration–response curves
Authors: Schürmeyer Leonie , Schorning Kirsten , Rahnenführer Jörg 
Published: October 2023

AbstractBackgroundAn important problem in toxicology in the context of gene expression data is the simultaneous inference of a large number of concentration–response relationships. The quality of the inference substantially depends on the choice of design of the experiments, in particular, on the set of different concentrations, at which observations are taken for the different genes under consideration. As this set has to be the same for all genes, the efficient planning of such experiments is very challenging. We address this problem by determining efficient designs for the simultaneous inference of a large number of concentration–response models. For that purpose, we both construct aD-optimality criterion for simultaneous inference and aK-means procedure which clusters the support points of the locallyD-optimal designs of the individual models.ResultsWe show that a planning of experiments that addresses the simultaneous inference of a large number of concentration–response relationships yields a substantially more accurate statistical analysis. In particular, we compare the performance of the constructed designs to the ones of other commonly used designs in terms ofD-efficiencies and in terms of the quality of the resulting model fits using a real data example dealing with valproic acid. For the quality comparison we perform an extensive simulation study.ConclusionsThe design maximizing theD-optimality criterion for simultaneous inference improves the inference of the different concentration–response relationships substantially. The design based on theK-means procedure also performs well, whereas a log-equidistant design, which was also included in the analysis, performs poorly in terms of the quality of the simultaneous inference. Based on our findings, theD-optimal design for simultaneous inference should be used for upcoming analyses dealing with high-dimensional gene expression data.

AbstractThe current threat of multidrug resistant strains necessitates development of alternatives to antibiotics such as bacteriophages. This study describes the isolation and characterization of a novel Salmonella Typhimurium phage ‘Arash’ from hospital wastewater in Leuven, Belgium. Arash has a myovirus morphology with a 95 nm capsid and a 140 nm tail. The host range of Arash is restricted to its isolation host. Approximately 86% of the phage particles are adsorbed to a host cell within 10 min. Arash has latent period of 65 min and burst size of 425 PFU/cell. Arash has a dsDNA genome of 180,819 bp with GC content of 53.02% with no similarities to any characterized phages, suggesting Arash as a novel species in the novel ‘Arashvirus’ genus. Arash carries no apparent lysogeny-, antibiotic resistance- nor virulence-related genes. Proteome analysis revealed 116 proteins as part of the mature phage particles of which 27 could be assigned a function. Therefore, the present findings shed light on the morphological, microbiological and genomic characteristics of Arash and suggest its potential application as therapeutic and/or biocontrol agent.
Implementing and evaluating care and support planning: a qualitative study of health professionals’ experiences in public polyclinics in Singapore

Published: October 2023

Abstract
Background
Two polyclinics in Singapore modified systems and trained health professionals to provide person-centred Care and Support Planning (CSP) for people with diabetes within a clinical trial. We aimed to investigate health professionals’ perspectives on CSP to inform future developments.

Methods
Qualitative research including 23 semi-structured interviews with 13 health professionals and 3 co-ordinators. Interpretive analysis, including considerations of how different understandings, enactments, experiences and evaluative judgements of CSP clustered across health professionals, and potential causal links between them.

Results
Both polyclinic teams introduced CSP and sustained it through COVID-19 disruptions. The first examples health professionals gave of CSP ‘going well’ all involved patients who came prepared, motivated and able to modify behaviours to improve their biomedical markers, but health professionals also said that they only occasionally saw such patients in practice. Health professionals’ accounts of how they conducted CSP conversations varied: some interpretations and reported enactments were less clearly aligned with the developers’ person-centred aspirations than others. Health professionals brought different communication skill repertoires to their encounters and responded variably to challenges to CSP that arose from: the linguistic and educational diversity of patients in this polyclinic context; the cultural shift that CSP involved; workload pressures; organisational factors that limited relational and informational continuity of care; and policies promoting biomedical measures as key indicators of healthcare quality. While all participants saw potential in CSP, they differed in the extent to which they recognised relational and experiential benefits of CSP (beyond biomedical benefits), and their recommendations for continuing its use beyond the clinical trial were contingent on several considerations. Our analysis shows how narrower and broader interpretive emphases and initial skill repertoires can interact with situational challenges and respectively constrain or extend health professionals’ ability to refine their skills with experiential learning, reduce or enhance the potential benefits of CSP, and erode or strengthen motivation to use CSP.

Conclusion
Health professionals’ interpretations of CSP, along with their communication skills, interact in complex ways with other features of healthcare systems and diverse patient-circumstance scenarios. They warrant careful attention in efforts to implement and evaluate person-centred support for people with long-term conditions.
Health effects of long-term care insurance on spouses of disabled people: a quasi-experimental study
Authors: Yi Yanling , Xin Jing , Liu Junxia , Wu Jing 
Published: October 2023

Abstract
Background
It is still uncertain whether and how formal long-term care (LTC) systems affect the health status of family members. This paper examines the health effects of long-term care insurance (LTCI) on spouses of disabled people in China.

Methods
The data is from China Health and Retirement Longitudinal Survey (CHARLS), a longitudinal survey of a nationally representative sample of Chinese residents aged 45 or older and their spouses, and China City Statistical Yearbook. Exploiting the regional variation in the implementation of LTCI in the first round of pilot cities in China, a difference-in-difference (DID) strategy is applied to identify the causal effects of LTCI on the health status of spouses of disabled people. We carefully identify the causal effects by controlling for city-level covariates, testing common trends between the treatment and control groups, combining propensity score matching (PSM) with DID, selecting the second round of pilot cities as the control group, controlling for city fixed effects (FE) instead of individual FE, and evaluating selection bias from omitted observable and unobservable factors.

Results
The introduction of LTCI in China reduces the number of painful body parts and the self-reported health score significantly, indicating that spouses of disabled people get physical health benefits from LTCI coverage. However, the impact of LTCI on the depression index remains ambiguous and needs to be analyzed further. LTCI improves the physical health status of spouses of disabled individuals mainly through the time reallocation channel, while the impact of the consumption promotion channel has not been verified. Furthermore, the beneficial effects of LTCI on physical health are stronger for spouse caregivers and spouses with lower-level education and lower household income.

Conclusion
These findings demonstrate that LTCI not only improves the health status of family caregivers by reducing their caregiving burden but also has beneficial health effects on non-caregiver family members. Policy designs of LTCI should emphasize the orientation of home and community-based care services (HCBS), which can not only satisfy the care preferences of disabled individuals, reduce the care burden on family caregivers, promote the health of all family members, but also prevent a large number of disabled individuals from choosing high-cost institutional care and reduce the financial burden of the LTCI Fund.
