How digital health solutions align with the roles and functions that support hospital to home transitions for older adults: a rapid review study protocol

Introduction Older adults may experience challenges during the hospital to home transitions that could be mitigated by digital health solutions. However, to promote adoption in practice and realise benefits, there is a need to specify how digital health solutions contribute to hospital to home transitions, particularly pertinent in this era of social distancing. This rapid review will: (1) elucidate the various roles and functions that have been developed to support hospital to home transitions of care, (2) identify existing digital health solutions that support hospital to home transitions of care, (3) identify gaps and new opportunities where digital health solutions can support these roles and functions and (4) create recommendations that will inform the design and structure of future digital health interventions that support hospital to home transitions for older adults (eg, the pre-trial results of the Digital Bridge intervention; ClinicalTrials.gov Identifier: NCT04287192). Methods and analysis A two-phase rapid review will be conducted to meet identified aims. In phase 1, a selective literature review will be used to generate a conceptual map of the roles and functions of individuals that support hospital to home transitions for older adults. In phase 2, a search on MEDLINE, EMBASE and CINAHL will identify literature on digital health solutions that support hospital to home transitions. The ways in which digital health solutions can support the roles and functions that facilitate these transitions will then be mapped in the analysis and generation of findings. Ethics and dissemination This protocol is a review of the literature and does not involve human subjects, and therefore, does not require ethics approval. This review will permit the identification of gaps and new opportunities for digital processes and platforms that enable care transitions and can help inform the design and implementation of future digital health interventions. Review findings will be disseminated through publications and presentations to key stakeholders.
Ponseti Method After Walking Age - A Multi-Centric Study of 429 Feet: Results, Possible Treatment Modifications and Outcomes According to Age Groups.

Objective Ponseti method is suitable to treat neglected clubfoot after the walking age. However, limited evidence exists on its effectiveness, outcomes and rate of relapse. Methods: 429 clubfeet in 303 patients with no previous treatment and older than one-year were treated with the Ponseti method in 15 centers from seven countries. The median age at treatment onset was three years, and the median follow-up of 1.3 years. Standard Ponseti Method was applied. Bilateral abduction brace was recommended after casting. Patients were classified according to group ages (<2 years, 2-4 years, >4-8years, >8 years). Feet were evaluated by Pirani score and a clinical outcome classification. Relapses were described in a subset of 103 clubfeet with minimal follow-up of two years. Results Ponseti method was able to correct the deformity in 87% (373 of 429) of neglected clubfeet, after a mean of 6.8 casts. Residual equinus was treated with percutaneous sectioning of the Achilles tendon in 356 (83%) of 429 clubfeet. A bilateral foot abduction brace was prescribed and used in 70% of children. Relapses occurred in 31% (32 of 103) of clubfeet and were associated with age less than 4 years at treatment onset, and bracing noncompliance. Conclusion The Ponseti method is effective to correct neglected clubfeet. Relapses occurred in one-third of clubfeet, mainly in children younger than four years and in noncompliance with the brace. Our study reinforces the recommendation for the Ponseti method with no major modification to treat neglected clubfoot in patients after walking age.Level of Evidence: IV.
PHO1 family members transport phosphate from infected nodule cells to bacteroids in Medicago truncatula

Abstract Legumes play an important role in the soil nitrogen availability via symbiotic nitrogen fixation (SNF). Phosphate (Pi) deficiency severely impacts SNF because of the high Pi requirement of symbiosis. Whereas PHT1 transporters are involved in Pi uptake into nodules, it is unknown how Pi is transferred from the plant infected cells to nitrogen-fixing bacteroids. We hypothesized that Medicago truncatula genes homologous to Arabidopsis PHO1, encoding a vascular apoplastic Pi exporter, are involved in Pi transfer to bacteroids. Among the seven MtPHO1 genes present in M. truncatula, we found that two genes, namely MtPHO1.1 and MtPHO1.2, were broadly expressed across the various nodule zones in addition to the root vascular system. Expressions of MtPHO1.1 and MtPHO1.2 in Nicotiana benthamiana mediated specific Pi export. Plants with nodule-specific downregulation of both MtPHO1.1 and MtPHO1.2 were generated by RNA interference (RNAi) to examine their roles in nodule Pi homeostasis. Nodules of RNAi plants had lower Pi content and a three-fold reduction in SNF, resulting in reduced shoot growth. Whereas the rate of 33Pi uptake into nodules of RNAi plants was similar to control, transfer of 33Pi from nodule cells into bacteroids was reduced and bacteroids activated their Pi-deficiency response. Our results implicate plant MtPHO1 genes in bacteroid Pi homeostasis and SNF via the transfer of Pi from nodule infected cells to bacteroids.
Registration of spatio-temporal point clouds of plants for phenotyping

Plant phenotyping is a central task in crop science and plant breeding. It involves measuring plant traits to describe the anatomy and physiology of plants and is used for deriving traits and evaluating plant performance. Traditional methods for phenotyping are often time-consuming operations involving substantial manual labor. The availability of 3D sensor data of plants obtained from laser scanners or modern depth cameras offers the potential to automate several of these phenotyping tasks. This automation can scale up the phenotyping measurements and evaluations that have to be performed to a larger number of plant samples and at a finer spatial and temporal resolution. In this paper, we investigate the problem of registering 3D point clouds of the plants over time and space. This means that we determine correspondences between point clouds of plants taken at different points in time and register them using a new, non-rigid registration approach. This approach has the potential to form the backbone for phenotyping applications aimed at tracking the traits of plants over time. The registration task involves finding data associations between measurements taken at different times while the plants grow and change their appearance, allowing 3D models taken at different points in time to be compared with each other. Registering plants over time is challenging due to its anisotropic growth, changing topology, and non-rigid motion in between the time of the measurements. Thus, we propose a novel approach that first extracts a compact representation of the plant in the form of a skeleton that encodes both topology and semantic information, and then use this skeletal structure to determine correspondences over time and drive the registration process. Through this approach, we can tackle the data association problem for the time-series point cloud data of plants effectively. We tested our approach on different datasets acquired over time and successfully registered the 3D plant point clouds recorded with a laser scanner. We demonstrate that our method allows for developing systems for automated temporal plant-trait analysis by tracking plant traits at an organ level.
Human skeletal muscle fiber type-specific responses to sprint interval and moderate-intensity continuous exercise: acute and training-induced changes.

There are limited and equivocal data regarding potential fiber type-specific differences in the human skeletal muscle response to sprint interval training (SIT), including how this compares to moderate-intensity continuous training (MICT). We examined mixed muscle and fiber type-specific responses to a single session (study 1) and 12 wk (study 2) of MICT and SIT using Western blotting. MICT consisted of 45 min of cycling at ~70% of maximal heart rate and SIT involved 3 x 20-sec 'all-out' sprints interspersed with 2 min of recovery. Changes in signaling proteins involved in mitochondrial biogenesis in mixed muscle and pooled fiber samples were similar after acute MICT and SIT. This included increases in the ratios of phosphorylated to total acetyl CoA carboxylase and p38 mitogen activated protein kinase protein content (main effects, p<0.05). Following training, mitochondrial content markers including the protein content of cytochrome c oxidase subunit IV and NADH:ubiquinone oxidoreductase subunit A9 were increased similarly in mixed muscle and type IIa fibers (main effects, p<0.05). In contrast, only MICT increased these markers of mitochondrial content in type I fibers (interactions, p<0.05). MICT and SIT also similarly increased the content of mitochondrial fusion proteins optic atrophy 1 (OPA1) and mitofusin 2 in mixed muscle, and OPA1 in pooled fibre samples (main effects, p<0.05). In summary, acute MICT and SIT elicited similar fiber type-specific responses of signaling proteins involved in mitochondrial biogenesis, whereas 12 wk of training revealed differential responses of mitochondrial content markers in type I but not type IIa fibers.
The role of dimer formation in the self-assemblies of DNA base molecules on Cu(111) surfaces: A scanning tunneling microscope study

For the purpose of understanding the self-assembly formation mechanism of DNA base molecules, guanine, adenine, cytosine, and thymine molecules were deposited on Cu(111) surfaces, and were observed using a low-temperature (≈80 K) scanning tunneling microscope (STM). Single-molecular-scale STM images revealed that guanine, adenine, and cytosine molecules can form ordered one- and/or two-dimensional unique structures, but thymine molecules, however, randomly aggregate into small clusters. Semiempirical molecular orbital (MO) calculation indicates that there exists predominantly stable dimer structures for the former three molecules, while such phenomena cannot be observed among the possible thymine dimer and even trimer structures. Based on experimental and theoretical results, we have concluded that specific hydrogen-bonded nucleus formation is a decisive process in the two-dimensional self-assembly formation of DNA base molecules on Cu(111) surfaces.
Assessment of Image Quality for Selective Intracoronary Contrast-Injected CT Angiography in a Hybrid Angio-CT System: A Feasibility Study in Swine

Purpose To compare image quality in selective intracoronary contrast-injected computed tomography angiography (Selective-CTA) with that in conventional intravenous contrast-injected CTA (IV-CTA). Materials and Methods Six pigs (35 to 40 kg) underwent both IV-CTA using an intravenous injection (60 mL) and Selective-CTA using an intracoronary injection (20 mL) through a guide-wire during/after percutaneous coronary intervention. Images of the common coronary artery were acquired. Scans were performed using a combined machine comprising an invasive coronary angiography suite and a 320-channel multi-slice CT scanner. Quantitative image quality parameters of CT attenuation, image noise, signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), mean lumen diameter (MLD), and mean lumen area (MLA) were measured and compared. Qualitative analysis was performed using intraclass correlation coefficient (ICC), which was calculated for analysis of interobserver agreement. Results Quantitative image quality, determined by assessing the uniformity of CT attenuation (399.06 vs. 330.21, p<0.001), image noise (24.93 vs. 18.43, p<0.001), SNR (16.43 vs. 18.52, p=0.005), and CNR (11.56 vs. 13.46, p=0.002), differed significantly between IV-CTA and Selective-CTA. MLD and MLA showed no significant difference overall (2.38 vs. 2.44, p=0.068, 4.72 vs. 4.95, p=0.078). The density of contrast agent was significantly lower for selective-CTA (13.13 mg/mL) than for IV-CTA (400 mg/mL). Agreement between observers was acceptable (ICC=0.79±0.08). Conclusion Our feasibility study in swine showed that compared to IV-CTA, Selective-CTA provides better image quality and requires less iodine contrast medium.
Physical Fitness and Health-related Quality of Life in Patients with Colorectal Cancer

Abstract Colorectal cancer is now a frequently treatable illness for most and a chronic disease for many. The number of people living with a diagnosis of colorectal cancer is thus expected to rise. Yet even after successful treatment, colorectal cancer survivors, mostly the elderly, frequently experience health problems and impaired health-related quality of life. We investigated the cross-sectional association between physical fitness, measured with the 6-min walk test, 30-second chair-stand test, and isometric handgrip strength, as well as health-related quality of life, in a cohort of colorectal cancer patients (n=71, mean [SD] age 67±10 years, 63% men; 35, 39 and 25% in stages I, II and III, respectively). Greater performance in the 6-minute walk test and 30-second chair-stand test was associated with higher levels of global health status (p<0.001, p=0.001 respectively), higher functioning (p<0.001) and lower levels of symptomatology (p<0.001; pain and fatigue). Additionally, greater 6-min walk test performance was associated with a better cognitive function (p=0.005). Our results suggest that greater aerobic fitness and lower-extremity muscle strength are cross-sectionally associated with higher levels of global health status, higher functioning and lower levels of symptomatology such as pain and fatigue in colorectal cancer patients.
Associations between insomnia and reward learning in clinical depression

Abstract Background Depression and insomnia commonly co-occur. Yet, little is known about the mechanisms through which insomnia influences depression. Recent research and theory highlight reward system dysfunction as a potential mediator of the relationship between insomnia and depression. This study is the first to examine the impact of insomnia on reward learning, a key component of reward system functioning, in clinical depression. Methods The sample consisted of 72 veterans with unipolar depression who endorsed sleep disturbance symptoms. Participants completed the Structured Clinical Interview for DSM-IV, self-report measures of insomnia, depression, and reward processing, and a previously validated signal detection task (Pizzagalli et al., 2005, Biological Psychiatry, 57(4), 319–327). Trial-by-trial response bias (RB) estimates calculated for each of the 200 task trials were examined using linear mixed-model analyses to investigate change in reward learning. Results Findings demonstrated diminished rate and magnitude of reward learning in the Insomnia group relative to the Hypersomnia/Mixed Symptom group across the task. Within the Insomnia group, participants with more severe insomnia evidenced the lowest rates of reward learning, with increased RB across the task with decreasing insomnia severity. Conclusions Among individuals with depression, insomnia is associated with decreased ability to learn associations between neutral stimuli and rewarding outcomes and/or modify behavior in response to differential receipt of reward. This attenuated reward learning may contribute to clinically meaningful decreases in motivation and increased withdrawal in this comorbid group. Results extend existing theory by highlighting impairments in reward learning specifically as a potential mediator of the association between insomnia and depression.
Point-of-care training program on COVID-19 infection prevention and control for pediatric healthcare workers: a multicenter, cross-sectional questionnaire survey in Shanghai, China

Background To evaluate the effectiveness of training on knowledge and practice of infection prevention and control (IPC) among pediatric health care workers (HCW) in Shanghai, China, in the context of COVID-19 pandemic. Methods An online training program was designed by the Shanghai Pediatric Clinical Quality Control Center (SPQCC) during the early phase of COVID-19 pandemic on disease knowledge and practice of IPC. Training took place in the 81 partner hospitals affiliated with SPQCC. A multicenter, cross-sectional questionnaire survey was designed with a 25-item self-administered questionnaire to evaluate the knowledge gained from the training. Stratified-random sampling was used to select HCW according to three professionals (i.e., pediatricians, nurses and administrators) within each partner hospital. Awareness and knowledge of COVID-19 and its related infection control and practice were assessed by comparing survey results between different types of hospitals, professionals and professional ranks. A higher survey score meant that the respondent was more prepared and knowledgeable about COVID-19 and its infection control measures. Results Completed questionnaires were returned from 1,062 subjects (385 pediatricians, 410 nurses, and 267 administrators), giving a response rate of 96.5%. Overall, awareness of clinical information related to COVID-19, importance of personal hygiene and isolation policy was high among the respondents. No statistical difference of scores on knowledge of COVID-19, IPC and relevant practice between the tertiary and peripheral hospitals. Among all respondents, middle-ranked health care personnel were most knowledgeable and achieved the highest score. Conclusions Majority of pediatric HCW showed good recognition and practice in infection protection and control measures. The online training was able to achieve its aim to enhance knowledge and awareness and could have contributed to the zero infection rate among HCW caring for confirmed COVID-19 cases in Shanghai.
Long-term outcomes of video-assisted lobectomy in non-small cell lung cancer

Background Video-assisted thoracoscopic surgery lobectomy combined with lymphadenectomy is widely utilized worldwide for treating non-small cell lung cancer. We evaluated the long-term survival outcomes of this approach and determined the prognostic factors of overall survival. Methods This prospective observational study was performed in patients with non-small cell lung cancer who were subjected to video-assisted lobectomy and lymphadenectomy from 2012 to 2016. Independent prognostic factors were determined via uni- and multivariable Cox models. Results There were 109 patients with the mean age of 59.2 years and males accounted for 54.1%. Postoperative staging determined 22.9% of stage IA, 31.2% of stage IB, 16.5% of stage IIA and 29.4% of stage IIIA. Median follow-up time was 27 months. The overall survival rate after 1, 2, 3, 4 and 5 years was 100%, 85.9%, 65.3%, 55.9% and 55.9%, respectively. In univariable analysis, smoking (hazard ratio (HR) [95% confidence interval (CI)]: 2.50 [1.18–5.31]), Tumor--nodes--metastases (TNM) stage (IIA: 7.60 [1.57–36.9]; IIIA: 14.3 [3.28–62.7] compared to IA), histological differentiation (moderately differentiated: 4.91 [1.04–23.2]; poorly differentiated: 8.25 [1.91–35.6] compared to well differentiated), lymph node size ≥1 cm (8.22 [3.11–21.7]), tumour size ≥3 cm (4.24 [1.01–17.9]), radical lymphadenectomy (6.67 [3.14–14.2]) were identified as prognostic factors of the long-term survival. In multivariable analysis, only radical lymphadenectomy was an independent prognostic factor (HR [95% CI]: 3.94 [1.41–11.0]). Conclusion Video-assisted thoracoscopic lobectomy combined with lymphadenectomy is feasible, safe and effective for the treatment of non-small cell lung cancer. The long-term outcomes of this method are favourable, especially at the early stage of cancer.
Systematic review of pediatric memory questionnaires

ABSTRACT Memory disturbances are common in children with neurological and developmental conditions. One way to measure memory disturbances and their functional implications is via a memory questionnaire. Several pediatric memory questionnaires have been published but no systematic review has been conducted to establish their psychometric properties. This review evaluated currently available pediatric memory questionnaires using the Evidence-Based Assessment (EBA) criteria developed by the American Psychological Association Task force. A systematic search of CINAHL, EMBASE, Medline, and PsychINFO was completed on June 2019. The selection process was guided by pre-defined inclusion and exclusion criteria, followed by full manuscript reviews, and hand-search of reference lists of relevant papers. Selected questionnaires were evaluated by two independent raters against the EBA criteria and classified into “well established”, “approaching well-established”, and “promising” categories. The electronic searches yielded 9888 articles, 24 of which met the inclusion criteria. Hand searches identified additional 21 studies. The 45 identified studies reported on 24 versions of 10 memory questionnaires assessed working memory, everyday memory, prospective and retrospective memory, and self-awareness of memory functions. Based on EBA criteria, only one memory questionnaire (The Working Memory Rating Scale – 20 item version) was classified as “well-established”, 3 as “approaching well-established”, and 20 as “promising”. Most (n = 19) had good reliability but lacked concurrent validity; had low or no correlations with objective memory tests, and low predictive power. In conclusion, this review highlights an urgent need for the development and validation of pediatric memory questionnaires to increase the evidence base and improve questionnaires’ clinical utility.
Use of a Self-Delivering Anti-CCL3 FANA Oligonucleotide as an Innovative Approach to Target Inflammation after Spinal Cord Injury

Abstract Secondary damage after spinal cord injury (SCI) occurs because of a sequence of events after the initial injury, including exacerbated inflammation that contributes to increased lesion size and poor locomotor recovery. Thus, mitigating secondary damage is critical to preserve neural tissue and improve neurologic outcome. In this work, we examined the therapeutic potential of a novel antisense oligonucleotide (ASO) with special chemical modifications [2′-deoxy-2-fluoro-D-arabinonucleic acid (FANA) ASO] for specifically inhibiting an inflammatory molecule in the injured spinal cord. The chemokine CCL3 plays a complex role in the activation and attraction of immune cells and is upregulated in the injured tissue after SCI. We used specific FANA ASO to inhibit CCL3 in a contusive mouse model of murine SCI. Our results show that self-delivering FANA ASO molecules targeting the chemokine CCL3 penetrate the spinal cord lesion site and suppress the expression of CCL3 transcripts. Furthermore, they reduce other proinflammatory cytokines such as tumor necrosis factor (TNF) and interleukin (IL)-1β after SCI. In summary, we demonstrate for the first time the potential of FANA ASO molecules to penetrate the spinal cord lesion site to specifically inhibit CCL3, reducing proinflammatory cytokines and improve functional recovery after SCI. This novel approach may be used in new treatment strategies for SCI and other pathologic conditions of the CNS.
