Assessment of Sleep Disturbances and Exhaustion in Mothers of Children With Atopic Dermatitis

Importance The well-being and development of children is strongly influenced by parents’ physical and psychosocial health. Data from small, clinic-based studies suggest that sleep loss may be common in parents of children with atopic dermatitis (AD), but longitudinal population-based studies are lacking. Objectives To compare sleep disturbances over time between mothers of children with and without AD and to determine whether these disturbances are associated with the child’s disease severity and the child’s sleep disturbances. Design, Setting, and Participants In the ongoing Avon Longitudinal Study of Parents and Children, all pregnant women residing in Avon, United Kingdom, with an expected delivery date between April 1, 1991, and December 31, 1992, were recruited. Analyses for this study, a secondary analysis of this cohort, were performed from September 2017 to September 2018. Mother-child pairs were followed up with a time-varying measure of child AD activity and severity and self-reported maternal sleep measures repeated at multiple time points between child ages 6 months and 11 years. Main Outcomes and Measures Time-varying binary measures of maternal sleep duration (<6 vs ≥6 hours per night), difficulty falling asleep, early morning awakening, subjectively insufficient sleep, and daytime exhaustion. Results The study followed up 13 988 mother-child pairs from birth for a median duration of 11 (interquartile range, 7-11) years. Among the cohort, 11 585 of 13 972 mothers (82.9%) were aged 21 to 34 years and 12 001 of 12 324 (97.4%) were of white race/ethnicity; 7220 of 13 978 children (51.7%) were male. Sleep duration (adjusted odds ratio [AOR], 1.09; 95% CI, 0.90-1.32) and early morning awakenings (AOR, 1.16; 95% CI, 0.93-1.46) were similar between mothers of children with and without AD. In contrast, mothers of children with AD were more likely to report difficulty falling asleep (AOR, 1.36; 95% CI, 1.01-1.83), subjectively insufficient sleep (AOR, 1.43; 95% CI, 1.24-1.66), and daytime exhaustion (AOR, 1.41; 95% CI, 1.12-1.78) independent of the child’s comorbid asthma and/or allergic rhinitis. For all measures, worse child AD severity was associated with worse maternal sleep outcomes. The magnitude and significance of the associations were largely unchanged after adjustment for child sleep disturbances. Conclusions and Relevance Mothers of children with AD reported difficulty falling asleep, subjectively insufficient sleep, and daytime exhaustion throughout the first 11 years of childhood. However, child sleep disturbances did not fully explain maternal sleep disturbances, and future research should investigate other mechanisms. In caring for children with AD, clinicians should consider maternal sleep disturbances and caregiver fatigue.
Quantitative Proteomics Links the Intermediate Filament Nestin to Resistance to Targeted BRAF Inhibition in Melanoma Cells*

The proteome and phosphoproteome have been determined for BRAF inhibitor resistant and sensitive cells by applying quantitative MS-based proteomics. We identified the intermediate filament protein nestin as one of the highest downregulated proteins in melanoma cells and tumors. The results reported reveal a link between loss of nestin and an invasive phenotype and provide a quantitative view of PI3K/Akt and integrin pathways involved in resistant and nestin knockout cells. Graphical Abstract Highlights Quantitative phosphoproteome of BRAF drug-resistance in melanoma cells. Cytoskeletal proteins are downregulated in resistant vs. sensitive cells. Nestin is associated with an invasive phenotype and resistance to MEK and BRAF inhibitors. Nestin depletion affects PI3K/AKT and integrin signaling similar to resistant cells. Targeted inhibition of mutated kinases using selective MAP kinase inhibitors in malignant melanoma often results in temporary improvement of clinical symptoms followed by rapid development of resistance. To gain insights in molecular processes that govern resistance, we performed SILAC-based quantitative proteomics profiling of vemurafenib-resistant and -sensitive melanoma cells. Among downregulated proteins in vemurafenib-resistant cell lines we detected multiple proteins involved in cytoskeletal organization and signaling, including the intermediate filament nestin, which was one of the most downregulated proteins. Previous studies showed that nestin is expressed in various types of solid tumors and its abundance correlates with malignant phenotype of transformed cells. However, the role of nestin in cancer cells regarding acquired resistance is still poorly understood. We performed CRISPR/Cas9 knockout of the nestin gene (NES) in vemurafenib-sensitive cells and showed that loss of nestin leads to increased cellular proliferation and colony formation upon treatment with BRAFV600E and MEK inhibitors. Moreover, nestin depletion led to increased invasiveness and metalloproteinase activity like the phenotype of melanoma cells with acquired resistance to the BRAF inhibitor. Finally, phosphoproteome analysis revealed that nestin depletion influenced signaling through integrin and PI3K/AKT/mTOR pathways and led to increased focal adhesion kinase abundance and phosphorylation. Taken together, our results reveal that nestin is associated with acquired vemurafenib resistance in melanoma cells.
The social brain and heart rate variability: Implications for psychotherapy

PURPOSE Humans evolved within the mammalian line as a highly social species. Indeed, sociality has been a major driver of human social intelligence. From birth, social relationships have emotional and self-regulating properties and operate through different body systems. This paper will explore how heart rate variability (HRV), an index of the vagal regulation of the heart and a central element of the physiological underpinnings of sociality, is related to mental health problems, with important implications for psychotherapy. METHODS We conducted a narrative review of the literature on the bi-directional links between prosocial motivations, HRV, and psychophysiological functioning. RESULTS HRV is associated not only with the ability to downregulate physiological arousal, but also with a variety of psychological and behavioural variables which are usually the target of psychotherapeutic interventions. A modern neurovisceral integration model can be employed to explain the complex intercorrelation between HRV and psychophysiological functioning. In particular, the link between HRV, the experience of inter- and intrapersonal safeness, and the inhibitory function of the prefrontal cortex will be explored in the context of prosocial motives, such as compassion, that alleviate and help prevent mental health difficulties. CONCLUSIONS Our knowledge of the social brain and its physiological underpinnings might influence important elements of a therapeutic intervention, from the initial assessment of patient's difficulties to the evaluation of therapy outcomes. PRACTITIONER POINTS Social relationships have emotional and self-regulating properties. The experience of inter- and intrapersonal safeness is connected to prosocial motives, such as compassion, and the inhibitory function of the prefrontal cortex. Social relationships and compassion influence different body systems, such as the vagus nerve. Many forms of psychopathology represent the activation of evolved, defensive strategies especially in contexts where there are few stimuli indicating safeness and social support. Heart rate variability predicts psychotherapy outcome.
Evaluation of anti-inflammatory impact of dexamethasone-loaded PCL-PEG-PCL micelles on endotoxin-induced uveitis in rabbits

Abstract The aim of this study was to investigate the capability of polycaprolactone-polyethylene glycol-polycaprolactone (PCL-PEG-PCL) micelles in improving the anti-inflammatory effects of dexamethasone (DEX). A film hydration method was used for the preparation of the DEX-loaded PCL-PEG-PCL micelles. In vitro cytotoxicity of the micelles obtained was investigated on L929 cells. Cellular uptake was studied by using flow cytometry and fluorescence microscopy. Anterior uveitis was induced in a group of rabbits by intravitreal injection of endotoxin from Salmonella typhimurium. The severity of inflammation-induced was clinically graded by using Hogan’s classification method. Protein concentration in the aqueous humor was also measured. The micelles exhibited suitable compatibility on L929 cells and were taken up by the cells in a concentration- and time-dependent manner. The DEX-loaded micelles could reduce the clinical symptoms of uveitis after a lag-time. At 24 and 36 h after the LPS injection, the PCL-PEG-PCL micelles showed a better inhibitory effect on uveitis than the marketed eye drop, the differences did not reach significant levels though. This study demonstrated the potential of the PCL-PEG-PCL micelles as carriers for DEX in treating anterior uveitis. However, this concept is still to be further investigated.
Practice of exclusive breastfeeding and its associated factors in a suburban area in Angola: a cross-sectional study

ABSTRACT BACKGROUND: Exclusive breastfeeding for six months is one of the measures with highest impact on prevention of child deaths. The determinants of breastfeeding practices are complex and differ between populations. This study aimed to identify factors associated with the prevalence of exclusive breastfeeding in a suburban area in Angola. DESIGN AND SETTING: Population-based cross-sectional study in the municipality of Cacuaco, Luanda. METHODS: A random sample of children under two years of age and their mothers was included. Prevalence ratios (PR) were estimated using Poisson regression based on a hierarchical model. RESULTS: 749 children and their mothers were surveyed, including 274 children under six months. Theprevalence of exclusive breastfeeding among children under six months was 51.5% (95% confidence interval, CI, 46.3-56.6%). Four variables were positively associated with exclusive breastfeeding at ages of under six months: number of prenatal visits (PR 1.11 for each visit after the first one; 95% CI 1.04-1.18), maternal occupation (other occupations versus self-employed) (PR 1.54; 95% CI 1.05-2.26), younger child age (PR 0.77 for each month; 95% CI 0.71-0.84) and female child (PR 1.34; 95% CI 1.02-1.76). CONCLUSIONS: Our findings showed that the prevalence of exclusive breastfeeding at six months was satisfactory, according to international recommendations. Factors associated with exclusive breastfeeding practices that had never been surveyed before in Angola were identified through this study. These data are particularly relevant in the context of high infant mortality and may be useful in planning actions aimed at improving child health through promotion of exclusive breastfeeding, in Angola and other countries.
Direct evidence for modulation of photosynthesis by an arbuscular mycorrhiza-induced carbon sink strength.

It has been suggested that plant carbon (C) use by symbiotic arbuscular mycorrhizal fungi (AMF) may be compensated by higher photosynthetic rates because fungal metabolism creates a strong C sink that prevents photosynthate accumulation and downregulation of photosynthesis. This mechanism remains largely unexplored and lacks experimental evidence. We report here two experiments showing that the experimental manipulation of the mycorrhizal C sink significantly affected the photosynthetic rates of cucumber host plants. We expected that a sudden reduction in sink strength would cause a significant reduction in photosynthetic rates, at least temporarily. Excision of part of the extraradical mycorrhizal mycelium from roots, and causing no disturbance to the plant, induced a sustained (10-40%) decline in photosynthetic rates that lasted from 30 min to several hours in plants that were well-nourished and hydrated, and in the absence of growth or photosynthesis promotion by mycorrhizal inoculation. This effect was though minor in plants growing at high (700 ppm) atmospheric CO2 . This is the first direct experimental evidence for the C sink strength effects exerted by arbuscular mycorrhizal symbionts on plant photosynthesis. It encourages further experimentation on mycorrhizal source-sink relations, and may have strong implications in large-scale assessments and modelling of plant photosynthesis.
Multi-Sensor Fusion Approach for Cuff-Less Blood Pressure Measurement

Ambulatory blood pressure (BP) provides valuable information for cardiovascular risk assessment. The present cuff-based devices are intrusive for long-term BP monitoring, whereas cuff-less BP measurement methods based on pulse transit time or multi-parameter are inferior in robustness and reliability by using electrocardiogram (ECG) and photoplethysmogram signals. This study examined a multi-sensor fusion-based platform and algorithm for systolic BP (SBP), mean arterial pressure (MAP), and diastolic BP (DBP) estimation. The proposed multi-sensor platform was comprised of one ECG sensor and two pulse pressure wave sensors for simultaneous signal collection. After extracting 35 features from the collected signals, a weakly supervised feature selection method was proposed for dimension reduction because the reference oscillometric technique-based BP are intermittent and can be redeemed as coarse-grained labels. BP models were then established using a multi-instance regression algorithm. A total of 85 participants including 17 hypertensive and 12 hypotensive patients were enrolled. Experimental results showed that the proposed approach exhibited good accuracy for diverse population with an estimation error of 1.62 ± 7.76 mmHg for SBP, 1.53 ± 6.03 mmHg for MAP, and 1.49 ± 5.52 for DBP, which complied with the association for the advancement of medical instrumentation standards in BP estimation. Moreover, the estimation accuracy is with random daily fluctuations rather than long-term degradation through a maximum two-month follow-up period indicated good robustness performance. These results suggest that the proposed approach is with high reliability and robustness and thus provides a novel insight for cuff-less BP measurement.
Cranial and spinal injuries in motorcycle accidents: A hospital-based study.

BACKGROUND Injuries caused by motorcycle accidents have been reported in several studies with an examination from a general trauma point of view. However, to our knowledge, there is no detailed study specific to central nervous system injuries. This research was focused on central nervous system injuries associated with motorcycle accidents. METHODS The medical records of 540 patients who were admitted to the emergency department between 2008 and 2016 as the result of a motorcycle accident were retrospectively evaluated. Data were collected from electronic medical records, follow-up forms, and radiological images. Information on patient age, gender, type and site of injury, helmet use, alcohol level, Glasgow Coma Scale score on admission, length of stay in the intensive care unit and hospital, neurological status on discharge, and follow-up was collected and analyzed. RESULTS A total of 486 of 540 patients (90%) were male, 54 (10%) were female, and the mean age was 31+-18 years (range: 2-85 years, median: 25 years). Cranial injuries were detected in 320 cases (59%). The distribution of cranial injuries was: epidural hemorrhage (12.6%), subdural hemorrhage (15.2%), depressed fracture (10.4%), linear fracture (23%), skull base fracture (5.5%), diffuse axonal injury (9.3%), subarachnoid hemorrhage (25.2%), intracerebral hemorrhage (13.5%), and contusion (26.3%). Spinal fractures were detected in 52 cases (9.6%). Twenty-two (4.07%) of the spinal fractures were observed in the cervical region, 10 (1.85%) in the thoracic region, and 20 (3.7%) in the lumbar region. The mean length of stay in the hospital was 8.2+-4 days and 7 days in the intensive care unit. Sixty-eight patients (12.6%) died. Traumatic cranial entities other than linear fracture were associated with an elevated level of mortality. A Glasgow Coma Scale score of 6 or less was associated with significant mortality (68%). CONCLUSION A detailed report of motorcycle accident-associated central nervous system injuries is provided. The use of protective equipment, such as helmets, significantly reduced the rate of cerebral injury and death.
Determinants of concussion diagnosis, symptomology, and resolution time in U.S. high school soccer players

ABSTRACT Determinants of concussion diagnosis, symptomology, and other sequelae have not been examined in high school soccer players. Using a sample of soccer-related head/neck injuries from the NATION Surveillance Program, we evaluated potential determinants (sex, injury history, injury mechanism, setting) of concussion characteristics. A total of 378 head/neck injuries were recorded, and 189 (50.0%) injuries from this sample, resulted in a concussion diagnosis. Odds of concussion diagnosis were 84% higher among female players compared with their male counterparts, and over two-fold higher in game settings compared with practice settings. We also observed several significant symptom dependencies, such as higher odds of difficulty concentrating (OR = 5.84, 95% CI = [2.99, 11.42]) given concurrent light sensitivity. Furthermore, we identified injury mechanism as a determinant of concussion symptom resolution time. Our results suggest that determinants of soccer-related concussions and their sequelae are multifactorial, and extend the existing literature with the potential to inform clinical practice.
Disease Burden in Osteoarthritis Is Similar to That of Rheumatoid Arthritis at Initial Rheumatology Visit and Significantly Greater Six Months Later

To analyze disease burden in osteoarthritis (OA) according to Multidimensional Health Assessment Questionnaire (MDHAQ)/Routine Assessment of Patient Index Data 3 (RAPID3) scores at the initial visit and the 6‐month follow‐up visit, compared with rheumatoid arthritis (RA) as a benchmark for high disease burden.
Open-Top Light-Sheet Microscopy Image Atlas of Prostate Core Needle Biopsies.

CONTEXT. — Ex vivo microscopy encompasses a range of techniques to examine fresh or fixed tissue with microscopic resolution, eliminating the need to embed the tissue in paraffin or produce a glass slide. One such technique is light-sheet microscopy, which enables rapid 3D imaging. Our pathology-engineering collaboration has resulted in an open-top light-sheet (OTLS) microscope that is specifically tailored to the needs of pathology practice. OBJECTIVE. — To present an image atlas of OTLS images of prostate core needle biopsies. DESIGN. — Core needle biopsies (N = 9) were obtained from fresh radical prostatectomy specimens. Each biopsy was fixed in formalin, dehydrated in ethanol, stained with TO-PRO3 and eosin, optically cleared, and imaged using OTLS microscopy. The biopsies were then processed, paraffin embedded, and sectioned. Hematoxylin-eosin and immunohistochemical staining for cytokeratin 5 and cytokeratin 8 was performed. RESULTS. — Benign and neoplastic histologic structures showed high fidelity between OTLS and traditional light microscopy. OTLS microscopy had no discernible effect on hematoxylin-eosin or immunohistochemical staining in this pilot study. The 3D histology information obtained using OTLS microscopy enabled new structural insights, including the observation of cribriform and well-formed gland morphologies within the same contiguous glandular structures, as well as the continuity of poorly formed glands with well-formed glands. CONCLUSIONS. — Three-dimensional OTLS microscopy images have a similar appearance to traditional hematoxylin-eosin histology images, with the added benefit of useful 3D structural information. Further studies are needed to continue to document the OTLS appearance of a wide range of tissues and to better understand 3D histologic structures.
Opioids in the immune system: from experimental studies to clinical practice.

INTRODUCTION Opioids interact with both innate and adaptive immune systems and have direct effects on opioid receptors located on immune cells. Research on this topic has provided evidence of the opioid influence on the immune response associated with surgical stress. The immunological effects of opioids are currently being investigated, particularly whether they influence the outcome of surgery or the underlying disease regarding important aspects like infection or cancer progression. This review addresses background research related to the influence of the opioid receptor on the immune system, the immunosuppressive effect associated with major opioids during the perioperative period, and their clinical relevance. The objective of the study was to review the effects of opioids on the immune system.
Approximate DCT Design for Video Encoding Based on Novel Truncation Scheme

This paper presents an energy- and area-efficient architecture for approximated discrete cosine transform (DCT). Due to the good compression ability, DCT is widely exploited in signal processing. However, it is computationally intensive especially for large transform sizes. In this paper, we have reduced the computation cost of DCT by truncating a couple of least significant bits (LSB), most significant bits (MSB), and zero columns. First, considering that the contribution of LSBs is weakened because of the final right shift operation, we have eliminated the computation process for some LSBs. For the addition of the remaining LSBs, a parallel carry propagation adder is proposed to reduce the calculation latency. Second, owing to the phenomenon that high-frequency components are quite small in natural scenes, a couple of MSBs are selectively truncated according to their positions. Third, quantization is taken into account for the system-level optimization. The quantized results of all-zero columns are utilized to skip the column transforms afterward. The experimental results show that at most 32% area consumption and 60% power consumption can be reduced compared with the originally accurate DCT, while the compression efficiency loss caused by the DCT approximation is negligible for High Efficiency Video Coding.
Model Free Adaptive Iterative Learning Consensus Tracking Control for a Class of Nonlinear Multiagent Systems

This paper proposes a distributed model free adaptive iterative learning control (MFAILC) method for a class of unknown nonlinear multiagent systems to perform consensus tracking. Here, both fixed and iteration-varying topologies are considered and only a subset of followers can access the desired trajectory in each topology. To design the control protocol, the agent’s dynamic is first transformed into a dynamic linearization model along the iteration axis, and then a distributed MFAILC scheme is constructed to guarantee that all agents can track the desired trajectory. Through rigorous analysis, it is shown that under this novel distributed MFAILC scheme, the tracking errors of all agents are convergent along the iteration axis. The main merit of this design is that consensus tracking task can be achieved only utilizing the input/output data of the multiagent system. Three examples are given to validate the effectiveness of the proposed design.
