Genetic architecture predisposes regions of the human genome to copy-number variants, which confer substantial disease risk, most prominently towards neurodevelopmental disorders. These variants typically contain multiple genes and are often associated with extensive pleiotropy and variable phenotypic expressivity. Despite the expansion of the fidelity of CNV detection, and the study of such lesions at the population level, understanding causal mechanisms for CNV phenotypes will require biological testing of constituent genes and their interactions. In this regard, model systems amenable to high-throughput phenotypic analysis of dosage-sensitive genes (and combinations thereof) are beginning to offer improved granularity of CNV-driven pathology. Here, we review the utility of Drosophila and zebrafish models for pathogenic CNV regions, highlight the advances made in discovery of single gene drivers and genetic interactions that determine specific CNV phenotypes, and argue for their validity in dissecting conserved developmental mechanisms associated with CNVs.
Monitoring vital signs in hospital is an important part of safe patient care. However, there are no robust estimates of the workload it generates for nursing staff. This makes it difficult to plan adequate staffing to ensure current monitoring protocols can be delivered.
To estimate the time taken to measure and record one set of patient's vital signs; and to identify factors associated with the time required to measure and record one set of patient's vital signs.
We undertook a time-and-motion study of 16 acute medical or surgical wards across four hospitals in England. Two trained observers followed a standard operating procedure to record the time taken to measure and record vital signs. We used mixed-effects models to estimate the mean time using whole vital signs rounds, which included equipment preparation, time spent taking vital signs at the bedside, vital signs documentation, and equipment storing. We tested whether our estimates were influenced by nurse, ward and hospital factors.
After exclrses save time when using electronic vital signs recording, or that the grade of staff measuring the vital signs influenced the time taken.
Measuring and recording vital signs is time consuming and the impact of interruptions and preparation away from the bedside is considerable. When considering the nursing workload around vital signs assessment, no assumption of relative efficiency should be made if different technologies or staff groups are deployed.

Strong family ties appear to buffer patient's and family members' difficult experiences during life and health crises. The family participatory dignity therapy programme, a patient-family-centred psychological intervention, was developed based on dignity therapy and performed by one therapist in the form of interview according to a specific question prompt.
This study aimed to confirm the efficacy of the family participatory dignity therapy programme in improving the psychological well-being and family cohesion and adaptability of patients with haematologic malignancies and their family caregivers.
A single-blinded, two-arm parallel group, randomised controlled trial was conducted.
and Participants Participants were patient-family caregiver dyads recruited from Fujian Medical University Union Hospital from March to September 2019.
A total of 68 eligible dyads agreed to participate and were randomly assigned to the intervention group (n=33) or control group receiving usual care (n=35). Each pair of pamily cohesion and adaptability, decreased their family caregivers' anxiety and depression, and enhanced the caregivers' family cohesion and adaptability.
The family participatory dignity therapy programme showed a positive effect on promoting patients' hope, spiritual well-being, and family cohesion and adaptability; amongst family caregivers, it decreased anxiety and depression, and enhanced family cohesion and adaptability. Registration number ChiCTR1900021433 Tweetable abstract The family participatory dignity therapy programme promoted patients' hope, spiritual well-being, and family cohesion and adaptability, decreased their family caregivers' anxiety and depression, and enhanced the caregivers' family cohesion and adaptability.The objective of this study was to evaluate the efficacy of ultraviolet C light (UVC) for inactivating Senecavirus A (SVA) on three different experimentally contaminated surfaces commonly found in swine farms. An experimental study under controlled conditions assessed the effect of UVC on an SVA isolate on coupons composed of three surface types cardboard, cloth, and plastic. Each coupon was inoculated with 2 mL of SVA (107.5 TCID50/mL) and 1 mL of PBS or 1 g of feces on the top or bottom surface of the coupon and allowed to dry (90 min at 25℃). Coupons were exposed to UVC in a commercially available pass-through chamber (PTC) for 5 min or in a simulated supply entry room (SER) for 120 min. After exposure, virus isolation was attempted from each coupon and virus titers were determined in cell culture. The efficacy of UVC was determined by the reduction in virus titer for the UVC treated groups compared to their respective non-treated positive controls. UVC was effective at inactivating SVA on plastic surface free of organic material. The plastic coupons inoculated with SVA and PBS had a significantly lower virus titer (>7-log reduction) in both the PTC and SER when compared to their relative positive controls. All other groups in the PTC and SER had a 2-log reduction or less. The reduction in virus titer on the top and bottom inoculated surfaces, following exposure to UVC, were not statistically different. The data from this study provide some guidance when applying UVC for disinfection in the field.
Walking with user-driven treadmill control is believed to be more like overground walking than fixed-speed treadmill walking. Walking speed and ground reaction forces differ between overground and fixed-speed treadmill walking, but not between overground and user-driven treadmill walking in healthy and post-stroke subjects. However, studies assessing spatiotemporal gait parameters during user-driven treadmill walking are limited. This information may help confirm that user-driven treadmill walking is more like overground walking than fixed-speed treadmill walking, as well as inform the development of post-stroke gait rehabilitation programs.
How do spatiotemporal gait parameters for individuals post-stroke differ between fixed-speed and user-driven treadmill walking?
Eighteen subjects (10 M, 8 F; 62 ± 12 years; 1.73 ± 0.12 m; 84.9 ± 12.9 kg; 40 ± 30 months post-stroke) with chronic post-stroke hemiparesis participated in this study. Participants walked on an instrumented treadmill in its fixed-speed andlitation may benefit from programs with user-driven treadmill training paradigms to improve mobility following stroke.
The results of this study show that user-driven treadmill control encourages healthy gait biomechanics and a greater sense of stability in post-stroke subjects. Individuals post-stroke walked with smaller step width with user-driven treadmill control, which has been associated with increased balance. read more Post-stroke gait rehabilitation may benefit from programs with user-driven treadmill training paradigms to improve mobility following stroke.
Children with cerebral palsy indicate poor continuous gait inter-limb coordination compared to typically developing children. Limited research exists in the understanding of the coordinative relationship between the arms and legs of these children and if the phasing relationships between limbs can be improved.
Which motor control factors impact coordination in children with cerebral palsy and can coordination improve with intervention?
This literature review provides a comprehensive overview of the current knowledge of continuous coordination in a pediatric, pathologic population with an emphasis on inter-limb coordination. Peer-reviewed research articles related to inter-limb coordination, with a focus on gait, were reviewed to identify relevant research and any gaps in the literature which could inform future study design. Consideration of the most appropriate analysis for evaluation of such movement is also presented.
The coordinative difficulties experienced by children with cerebral palsy may oriositive impact on gait coordination in children with cerebral palsy.
Improved upper extremity function may produce a positive change in the phasing relationship between the arms and legs. This type of coordination should be analyzed using relative phase analysis, as this type of analysis can provide more information compared to traditional spatiotemporal parameters. However, more research is required to fully understand the connection between improved upper extremity function and its positive impact on gait coordination in children with cerebral palsy.Flexible bioassays based on oxidase-catalyzed and electrocatalytic cascade reactions have been widely reported. However, the fluctuant oxygen level and high anodic potential restricts the detection accuracy. To overcome these challenges, we report here a flexible triphase enzyme electrode by assembling an oxidase enzyme layer and Pt electrocatalysts onto a carbon nanotube film/porous polyvinylidene fluoride hydrophobic substrate. Such a flexible enzyme electrode has an air-liquid-solid triphase reaction zone where oxygen level is air phase dependent (constant and sufficient high), which stabilized the oxidase kinetics and enabled the cathodic measurement of enzymatic product H2O2 with minimum interferents caused from oxygen level fluctuation and many oxidizable species in analyte solution. Furthermore, the flexible triphase enzyme electrode exhibited good mechanical stability even after being bent over 600 times and an excellent air permeability, which are crucial to wearable devices that require long-term skin contact.In line with the increase in orthopedic prosthetic surgeries, there has been a significant rise in periprosthetic joint infections (PJI) due to Methicillin-Resistant Staphylococcus Aureus (MRSA) bacteria. In case of infection, antibiotic-added spacers are temporarily placed into the periprosthetic region. With the release of antibiotics usually failing to work in fighting off infection, recent studies have centered around developing more effective approaches. New polymethylmethacrylate (PMMA) cement mixtures were prepared for this study with Pluronic®F127, bicarbonate, and citric acid addition. Optimal solutions were searched by monitoring vancomycin release on consecutive days with HPLC in in-vitro. The strengths of the samples were measured via four-point bending tests. Compared to conventional PMMA, strength values were observed to have improved by about 20% with 1.0 g of Pluronic®F127. According to HPLC studies, the highest increase for the area under the curve value was obtained for Pluronic®F127 doped mixture with a value of about 20%.
