Published: March 2022

AbstractStem-cell derived in vitro cardiac models have provided profound insights into mechanisms in cardiac development and disease. Efficient differentiation of specific cardiac cell types from human pluripotent stem cells using a three-step Wnt signaling modulation has been one of the major discoveries that has enabled personalized cardiovascular disease modeling approaches. Generation of cardiac cell types follow key development stages during embryogenesis, they intuitively are excellent models to study cardiac tissue patterning in primitive cardiac structures. Here, we provide a brief overview of protocols that have laid the foundation for derivation of stem-cell derived three-dimensional cardiac models. Further this article highlights features and utility of the models to distinguish the advantages and trade-offs in modeling embryonic development and disease processes. Finally, we discuss the challenges in improving robustness in the current models and utilizing developmental principles to bring higher physiological relevance. In vitro human cardiac models are complimentary tools that allow mechanistic interrogation in a reductionist way. The unique advantage of utilizing patient specific stem cells and continued improvements in generating reliable organoid mimics of the heart will boost predictive power of these tools in basic and translational research.

Abstract
Background
Reconstruction surgery-associated stricture frequently occurs in patients with long-gap esophageal atresia (LGEA). While several endoscopic dilatation methods have been applied and would be desirable, endoscopic recanalization is very difficult in cases with complete esophageal closure. Surgical treatment has been performed for a severe stricture, which causes extensive damage to the infant. No reports have described successful endoscopic recanalization for complete closure due to scarring after surgery for LGEA. We herein report the case of successful endoscopic recanalization by single endoscopist in an LGEA patient with complete closure after reconstruction surgery.

Case presentation
A seven-month-old boy with LGEA who received reconstruction surgery and gastrostomy immediately after birth presented to our unit due to vomiting and malnutrition. Contrast radiography and peroral endoscopy detected complete closure of the esophagus at the anastomotic site. After confirming the length of stricture as several millimeters, we punctured the center of the lumen with a 25-G puncture needle under fluoroscopy. An endoscope was then inserted via the gastrostomy and the puncture hole was detected at the center of the lumen. After passing the guidewire, endoscopic balloon dilation was performed three times, and the hole was sufficiently dilatated. Oral ingestion was feasible, and his nutritional condition was improved.

Conclusions
To our knowledge, this is the first report to propose a less invasive endoscopic approach to recanalize a site of complete esophageal closure in a LGEA patient after reconstruction surgery by single endoscopist. Our endoscopic procedure using an ultrathin endoscope and puncture needle may be a therapeutic option for the treatment of patients with complete esophageal closure in a LGEA patient after reconstruction surgery.

Published: March 2022

Abstract
Background
Among all physical activities, walking is one of the easiest and most economical activities for older adults’ mental and physical health. Although promoting social participation may extend the walking time of older adults, the longitudinal relationship is not well understood. Thus, this study elucidates the relationship between nine types of social participation and change in walking time during a 3-year follow-up of older adults.

Methods
We conducted a 3-year community-based longitudinal study of independent older adults in Japan. From the 2016 and 2019 surveys, we extracted 57,042 individuals. We performed multiple regression analyses, estimating associations between change in walking time after three years and nine types of social participation in 2016: volunteer, sports, hobby, senior, neighborhood, learning, health, skills, and paid work. We conducted subgroup analysis stratified by walking time in 2016 (i.e., < 60 or ≥ 60 min/day).

Results
The mean (standard deviation) change in walking time for 3 years was − 4.04 (29.4) min/day. After adjusting potential confounders, the significant predictors of increasing or maintaining walking time (min/day) were participation in paid work (+ 3.02) in the < 60 min/day subgroup; and volunteer (+ 2.15), sports (+ 2.89), hobby (+ 1.71), senior (+ 1.27), neighborhood (+ 1.70), learning (+ 1.65), health (+ 1.74), and skills (+ 1.95) in the ≥ 60 min/day subgroup compared with non-participants.

Conclusions
Paid work and community activities may be effective for maintaining or increasing walking time among older adults with less (< 60 min/day) and sufficient (≥ 60 min/day) walking time, respectively.

AbstractIntroductionAgeing entails a series of neuroanatomical and neurophysiological changes in some cognitive processes that directly affect the daily life and autonomy of a person. We believe it is necessary to have tools that assess the cognitive functions that are essential for carrying out daily activities in an independent manner. The aim of this study was to translate the Everyday Cognition Battery (ECB) into Spanish, adapt it to the sociocultural context of Spain, and validate it by testing the psychometric properties, i.e., the reliability and validity of the translated version.MethodsThe translation and adaptation of the ECB into Spanish was carried out following the method recommended by Beaton et al., the process concluding with a pilot test to ensure that subjects were able to understand the scale correctly. Between March and October 2019, the study population voluntarily completed the translated version of each of the four subscales that make up the battery of tests.The translated version was validated by analysing its psychometric properties, using reliability or internal consistency tests assessed with Cronbach’s alpha coefficient and validity tests analysed using correlation tables and Spearman’s correlation coefficient. The scale considered to represent the gold standard in the assessment of cognition was the Rapid Assessment of Cognitive Functions (RACF), and to assess Instrumental Activities of Daily Living (IADL) this was the Lawton and Brody Index.ResultsThe total study population included 226 subjects, of which 52 participants were excluded, resulting in a study sample size of 174 older adults. The recognition, inductive reasoning and computation span tests showed good reliability (Cronbach’s alpha coefficient of > 0.827, > 0.836, and > 0.823, respectively), while the knowledge test showed questionable reliability with a Cronbach’s alpha coefficient of > 0.615. The validity analysis demonstrated that all the combinations of correlations of the different scales were significantly and positively related to one another.ConclusionsThe Spanish version of the ECB tool is socially and culturally equivalent to the original version, and both its validity and reliability for assessing everyday cognition in older adults have been demonstrated.

AbstractBackgroundHuman papillomavirus (HPV) is the most common sexually transmitted infection worldwide, affecting about 80% of women up to the age of 50. The persistent infection of high risk-HPV types (HR-HPV) is the leading cause of cervical cancer, the fourth most common cancer of women. Therefore, we aimed to evaluate the frequency and typing of HPV in the genital lesions in the Iranian population.MethodsThis descriptive-analytic study was conducted on a population in the South-Khorasan province of Iran. All of the participants were sexually active and were checked for evident cervical warts. Biopsy samples were collected from various lesions, and all samples were tested for detection and genotyping of HPV using a reverse dot blot hybridization method (HPV direct flow CHIP).ResultsIn overall, 370 samples were evaluated; 10 cases (2.7%) were male and the rest were female. The mean age of patients was 33.3 ± 8.5 years, of which 48.1% were in the age range from 25 to 36 years. Among the samples, 345 (93.2%) were positive for HPV-DNA; the low risk HPV types (LR-HPV) and HR-HPV were identified among 80.9% and 15.5% of tissue samples, respectively. Among the LR-HPV, HPV-6, 11, 42 and 54 were the most common genotypes, and HPV-16 and 39 were prevalent HR-HPV types detected. The number of pregnancies, marriage age, and partner infection were not significantly related to the HPV types. Types 42 had a declining pattern toward aging, and HPV-11 was increasing toward aging.ConclusionThe number of samples with HR-HPV was rather high. Due to the greater frequency of infection in the age range of 25–35 years, it is advised that all individuals referred to gynecological clinics at gestational age be tested for HPV types.
Development of CNN models for the enteral feeding tube positioning assessment on a small scale data set

Published: March 2022

Abstract
Background
Enteral nutrition through feeding tubes serves as the primary method of nutritional supplementation for patients unable to feed themselves. Plain radiographs are routinely used to confirm the position of the Nasoenteric feeding tubes the following insertion and before the commencement of tube feeds. Convolutional neural networks (CNNs) have shown encouraging results in assisting the tube positioning assessment. However, robust CNNs are often trained using large amounts of manually annotated data, which challenges applying CNNs on enteral feeding tube positioning assessment.

Method
We build a CNN model for feeding tube positioning assessment by pre-training the model under a weakly supervised fashion on large quantities of radiographs. Since most of the model was pre-trained, a small amount of labeled data is needed when fine-tuning the model for tube positioning assessment. We demonstrate the proposed method using a small dataset with 175 radiographs.

Result
The experimental result shows that the proposed model improves the area under the receiver operating characteristic curve (AUC) by up to 35.71% , from 0.56 to 0.76, and 14.49% on the accuracy, from 0.69 to 0.79 when compared with the no pre-trained method. The proposed method also has up to 40% less error when estimating its prediction confidence.

Conclusion
Our evaluation results show that the proposed model has a high prediction accuracy and a more accurate estimated prediction confidence when compared to the no pre-trained model and other baseline models. The proposed method can be potentially used for assessing the enteral tube positioning. It also provides a strong baseline for future studies.
Pregnancy planning health information and service needs of women with chronic non-communicable conditions: a systematic review and narrative synthesis

AbstractBackgroundPreparing for pregnancy and being in the best possible health before conception improves reproductive outcomes. For women living with a chronic non-communicable disease (NCD), pregnancy planning is essential to allow optimal disease control in preparation for pregnancy.AimThe aim was to review the literature relating to the pregnancy planning health information and service needs of women with NCDs.MethodThe MEDLINE (Ovid), Embase (Ovid), Emcare (Ovid), PsycINFO (Ovid), CINAHL and Scopus databases were searched. Studies were included if they were published in peer-reviewed English language journals between January 2010 and June 2020 and reported on the pregnancy planning health information and service needs of women with rheumatic diseases, asthma, cystic fibrosis, depression and/or anxiety, type 1 diabetes mellitus, epilepsy, or multiple sclerosis. Risk of bias was assessed using QualSyst. The characteristics of the studies were tabulated and summarised. Key findings of the included studies were analysed thematically using an inductive approach, where the study findings determined the themes. Findings are reported in a narrative synthesis.ResultsThe database searches yielded 8291 results, of which 4304 remained after duplicates were removed. After abstract screening 104 full-text papers were reviewed. Of these 15 met inclusion criteria and were included in analysis. The narrative synthesis of the included studies revealed six themes: ‘Women with chronic conditions have unmet preconception health information needs’, ‘Women with chronic conditions want personalised preconception health information’, ‘Preferred sources of preconception health information’, ‘Learning from the experiences of other women’, ‘Improving preconception health discussions with health care professionals’, and ‘Women want holistic care’. These themes were consistent across all studies, highlighting the similarity of experiences and needs of women with different chronic conditions.ConclusionTo improve pregnancy outcomes for women living with NCDs, health care providers need to ask women of reproductive age proactively and routinely about their pregnancy intentions and provide them with personalised advice on how to avoid unplanned pregnancy and be in optimal health when they wish to conceive.PROSPERO registration number CRD42020176308.
Cumulative live birth rates for low-prognosis women over 5 years or 9 frozen-thawed embryo transfer cycles
Authors: Chen Di , Shen Xi , Wang Li , Kuang Yanping 
Published: March 2022

Abstract
Background
For heterogeneous populations of low-prognosis women, it remains unclear as to how long individuals should continue undergoing ART when attempting to have a baby, as there have been insufficient studies to date tracking the cumulative live birth rates (CLBRs) for these women over the entire course of their ART treatment, particularly over extended time periods.

Methods
This was a retrospective analysis of 17,698 women at a tertiary care academic medical center who had begun undergoing IVI/ICSI cycles using a progestin-primed ovarian stimulation (PPOS) approach between January 2013 and January 2019. Low-prognosis patients were stratified into four groups based upon POSEIDON criteria, with patients exhibiting normal or high ovarian reserves and response to stimulation (defined as AFC ≥5, > 9 oocytes retrieved) being included as controls (group 5). The CLBR within 5 years or 9 FET cycles from the ovum pick-up (OPU) day of the first cycle was the primary endpoint for this study, including all repetitive oocyte retrieval cycles and subsequent FET cycles. Optimistic and conservative approaches were used for the analysis of CLBRs and the depiction of cumulative incidence curves.

Results
Under both optimistic and conservative model analyses, normal and good responders exhibited the highest CLBR within 5 years or 9 FET cycles, followed by younger unexpected poor responders, younger expected poor responders, older unexpected poor responders, and older expected poor responders. Upward trends in CLBRs were evident across the five groups with the prolongation of time or an increase in FET cycle counts. Within the first 2 years or 3 FET cycles, the CLBRs rose rapidly, followed by more moderate increases over the following 2–3.5 years or 4–6 cycles, with expected poor responders exhibiting the most obvious improvements. All Patients reached a CLBR plateau after 3.5 years or 6 FET cycles.

Conclusions
All low-prognosis women should undergo ART treatment for a minimum of 2 years or 3 FET cycles, and exhibit better outcomes when extending ART treatment to 3.5 years or 6 FET cycles (particularly for POSEIDON groups 3 and 4), but should consider ceasing further treatment thereafter due to a lack of apparent benefit.
Clinical characteristics of virus-related uveitic secondary glaucoma: focus on cytomegalovirus and varicella zoster virus
Authors: Fan Xintong , Li Zhizhe , Zhai Ruyi , Sheng Qilian , Kong Xiangmei 
Published: March 2022

Abstract
Background
We aimed to analyze the clinical characteristics of secondary glaucoma related to cytomegalovirus (CMV)- and varicella zoster virus (VZV)-positive uveitis.

Methods
In this retrospective study, we enrolled patients with anterior uveitic secondary glaucoma. All the patients underwent aqueous and serum analyses for viral antibody through enzyme-linked immunosorbent assay. Among the 60 included patients, 22 had CMV-negative Posner-Schlossman syndrome (CMV-negative PSS), 25 had CMV-positive PSS, and 13 had VZV-positive anterior uveitis secondary glaucoma (VZV-AUSG). We evaluated the following main indicators: age, disease duration, intraocular pressure (IOP), cup-to-disc ratio, best corrected visual acuity (BCVA), corneal endothelial cell (CEC) count, ocular morphological changes, and medical treatments.

Results
We found that 53.2% (25/47) patients with PSS were CMV-positive. Patients with CMV-positive PSS had a larger cup-to-disc ratio (p = .043), lower CEC density (p = .017), more severe CEC loss (p < .001), and more iris depigmentation (p = .006) than CMV-negative PSS patients. Compared with patients with CMV-positive PSS, those with VZV-AUSG were older (p = .003), presented a higher IOP (p = .015), and had poorer BCVA (p < .001). Patients with CMV-positive PSS and VZV-AUSG all accepted ganciclovir treatment, and those with CMV-positive PSS used fewer antiglaucoma agents simultaneously compared with CMV-negative PSS (p = .005) and VZV-AUSG (p < .001). All three groups had a comparable proportion of patients requiring antiglaucoma surgery.

Conclusions
We observed some distinctive clinical features in CMV-positive PSS compared with CMV-negative PSS. Further, we found that patients with VZV-AUSG presented with a higher IOP and worse visual acuity, and required more antiglaucoma medication than those with CMV-positive PSS.

Authors: Fleissig Efrat , Sigford Douglas Kenneth 
Published: March 2022

Abstract
Purpose
To investigate the contralateral effect of extended release steroid implants on cystoid macular edema (CME).

Methods
Retrospective study of patients with bilateral CME receiving intravitreal injections of long-acting intravitreal corticosteroid implants in one eye. Changes in CME and central subfield thickness (CST) in the contralateral eye on optical coherence tomography (OCT) were compared to an untreated control group. The main outcome measures were the change in central subfield thickness (CST) and the change in the macular volume.

Results
Thirteen study patients and 14 controls were included in the study. There was no difference in the baseline LogMAR visual acuity (0.32 ± 0.35 vs 0.43 ± 0.26, p = 0.37) or the baseline central subfield thickness (341.4 ± 76.6 vs 296.5 ± 65.0 µm, p = 0.12) between groups. In the treatment group CST remained stable in 92.3% of the patients. Of the controls, CST worsened in 21.4% and remained stable in 78.6%. The mean change in CST (6.3 ± 30.3 vs. 27.5 ± 66.1 µm, p = 0.2) and the mean change in macular volume (0.08 ± 0.34 vs. -0.05 ± 0.21 mm3, P = 0.8) were not statistically different between the treatment group and control group. In the post-hoc analysis restricting the treatment group to patients who had not received intravitreal injections in the study eye within 6 months, CST decrement was not statistically significant (p = 0.11).

Conclusion
In this study there was no statistically significant effect on CME of contralateral intravitreal corticosteroid implants.
Adherence to behaviours associated with the test, trace, and isolate system: an analysis using the theoretical domains framework

Published: March 2022

Abstract
Background
The UK’s test, trace, and isolate system are key measures to reduce the impact and spread of COVID-19. However, engagement with and adherence to guidance on testing, self-isolation, and providing details of contacts can be low and interventions are needed. This qualitative study aimed to identify the key factors affecting adherence to test, trace, and isolate behaviours using the Theoretical Domains Framework (TDF).

Methods
We conducted six online focus groups between October 2020 and February 2021 with people living in Sheffield who came into close contact with others in work or social settings (N = 30). The focus groups explored capability, opportunity, and motivational barriers to adherence to test, trace, and isolate behaviours. Framework analysis was used to code the data into TDF domains.

Results
There is a complex relationship between the factors affecting COVID-19 symptom identification, testing, and self-isolation. People who perceived significant barriers to testing and self-isolation were less likely to interpret potential symptoms as COVID-19, and perceiving barriers to self-isolation reduced the likelihood of requesting a test. Concerns about the negative consequences of self-isolation for themselves and others were common and also influenced willingness to pass on details of contacts. There was a lack of trust in the Test and Trace system, with people wanting further evidence of being at risk of infection.

Conclusions
Communications and interventions to increase adherence to test, trace, and isolate strategies need to consider the interplay of these behaviours and their influences and target them collectively. Efforts to promote testing should focus on the range of barriers to self-isolation, especially increasing financial and practical support, and include new messaging to promote symptom identification.
