Effective self-management of chronic obstructive pulmonary disease (COPD) can lead to increased patient control and reduced health care costs. However, both patients and healthcare professionals encounter significant challenges. Digital health interventions, such as smart oximeters and COPD self-management applications, promise to enhance the management of COPD, yet, there is little evidence to support their use and user-experience issues are still common. Understanding the needs of healthcare professionals is central for increasing adoption and engagement with digital health interventions but little is known about their perceptions of digital health interventions in COPD. This paper explored the perceptions of healthcare professionals regarding the potential role for DHI in the management of COPD. Snowball sampling was used to recruit the participants (n = 32). Each participant underwent a semi-structured interview. Using NVivo 12 software, thematic analysis was completed. Healthcare professionals perceive digital health interventions providing several potential benefits to the management of COPD including the capture of patient status indicators during the interappointment period, providing new patient data to support the consultation process and perceived digital health interventions as a potential means to improve patient engagement. The findings offer new insights regarding potential future use-cases for digital health interventions in COPD, which can help ease user-experience issues as they align with the needs of healthcare professionals.The novel 2019 coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a highly transmissible and pathogenic coronavirus. Because of the novelty of the COVID-19 pandemic, few data are available on the impact of the SARS-CoV-2 on the different endocrine glands. Previous studies of severe acute respiratory syndrome (SARS) have shown a harmful effect on endocrine function. Notably, the angiotensin-converting enzyme-2 receptor, which is the entry route of coronaviruses to the host cell, is widely expressed in the endocrine organs including testis, endocrine pancreas, thyroid, and adrenal, and pituitary glands. Clinical and biochemical manifestations have been recorded in COVID-19 patients resulting in changes in endocrine activities, which were also recorded during the SARS outbreak in 2003. This review aims to explore the impact of SARS-CoV-2 infection on the function of endocrine glands, based on the latest research in the field.Introduction As the global burden of Alzheimer's disease (AD) grows, an effective disease-modifying therapy remains a distant prospect following the repeated failure of multiple therapeutics targeting β-amyloid and (it seems) tau over many years of costly effort. The repeated failure of single-target therapies to meaningfully modify disease progression raises major questions about the validity of many aspects of drug development in this area, especially target selection.Area covered The authors explore the critical questions raised by a review of the collective experience to date, relating to why findings with non-clinical models and clinical biomarkers so frequently fail to translate to positive outcomes in clinical trials, which alternatives should be considered, and how we can design and conduct clinical trials that can successfully identify and quantify meaningful benefits in the future.Expert opinion It is our opinion that we must recognize and accept the need to consider less specific, more multimodal approaches to addressing neurodegeneration in AD if we are to make progress - and we must avoid repeating the well intentioned, but ultimately erroneous, assumptions of the past.Objectives With increasing treatment choices for inflammatory bowel disease (IBD), patients' preferences should be considered to limit non-adherence. WZB117 concentration We explored patients' preferences for route, form and frequency of medication administration, and factors influencing these choices.Methods Patients rated acceptability of different forms of medication on 10-point Likert scales and preferences for highest acceptable frequency.Results Of 298 patients significantly more found tablets (91%) to be highly acceptable compared to granules (64%), infusions (33%) and subcutaneous injections (34%; p less then 0.0001). The acceptable frequency for tablets was considered as daily by 63.5% and several times daily by 32.3%. Participants preferred nurse delivered over self-administered injections (median score 8 vs 5, p less then 0.0001) and hospital-based infusions over infusions at home (median score 7 vs 5, p = 0.001). Patients with previous or current anti-TNF exposure were more accepting of self-administered injections (50.5% vs 23.3% anti-TNF naive; p less then 0.001), more accepting of home based infusions (43.7% vs 28.0%; p = 0.001) and more accepting of hospital-based infusions (57.2% vs 37.8%; p = 0.02).Conclusion Most patients with IBD prefer tablets. Those patients who already experienced biological agents, had a high level of acceptance for subcutaneous and intravenous forms of medication.
Rapid development in mobile phone technologies increase the average mobile phone usage duration. This increase also triggers exposure to radiofrequency radiation (RF), which is a risk factor for the health. In this study, it was aimed to investigate the effect of mobile phone working with LTE-Advanced Pro (4.5G) mobile network on the optic nerve, which is responsible for the transmission of visual information.
Thirty-two rats divided into two groups as control (no RF, sham exposure) and experimental (RF exposure using a mobile phone with LTE-Advanced Pro network; 2 hours/day, 6 weeks). The visual evoked potential (VEP) was recorded and determined amplitudes and latencies of VEP waves. Optic nerve malondialdehyde level, catalase and superoxide dismutase activities were determined. Furthermore, ultrastructural and morphometric changes of optic nerve were evaluated.
In VEP recordings, the mean VEP amplitudes of experimental group were significantly lower than control group. In ultrastructural evaluation, myelinated nerve fibers and glial cells were observed in normal histologic appearance both in sham and experimental group. However, by performing morphometric analysis, in the experimental group, axonal diameter and myelin thickness were shown to be lower and the G-ratio was higher than in the sham group. In the experimental group, malondialdehyde level was significantly higher and superoxide dismutase and catalase activities were significantly lower than sham group. There was a high correlation between VEP wave amplitudes and oxidative stress markers.
Findings obtained in this study support optic nerve damage. These results point out an important risk that may decrease the quality of life.

The present study was undertaken to test the hypothesis that the elevated COMMD1 is responsible for copper loss from the ischemic myocardium, thus worsening myocardial ischemic injury. Mice (C57BL/6J) were subjected to left anterior descending coronary artery permanent ligation to induce myocardial ischemic infarction. In the ischemic myocardium, copper reduction was associated with a significant increase in the protein level of COMMD1. A tamoxifen-inducible, cardiomyocyte -specific Commd1 knockout mouse (C57BL/6J) model (COMMD1CMC▲/▲) was generated using the Cre-LoxP recombination system. COMMD1CMC▲/▲ and wild-type littermates were subjected to the same permanent ligation of left anterior descending coronary artery. At the 7th day after ischemic insult, COMMD1 deficiency suppressed copper loss in the heart, along with preservation of vascular endothelial growth factor and vascular endothelial growth factor receptor 1 expression and the integrity of the vascular system in the ischemic myocardium. Corresponding to this change, infarct size of ischemic heart was reduced and myocardial contractile function was well preserved in COMMD1CMC▲/▲ mice. These results thus demonstrate that upregulation of COMMD1 is at least partially responsible for copper efflux from the ischemic heart. Cardiomyocyte-specific deletion of COMMD1 helps preserve the availability of copper for angiogenesis, thus suppressing myocardial ischemic dysfunction.There are good evidences suggesting that endoplasmic reticulum (ER) stress can be one of the contributing factors in the development of diabetic retinopathy. The present study was designed to investigate the effect of chemical chaperone 4-phenylbutyric acid (4-PBA) in alleviating the ER stress, and diabetic retinopathy in type 2 diabetic rats. Treatment of diabetic rats with 4-PBA, increased the antioxidant capacity, reduced the levels of lipid peroxidation, organised the state of apoptosis and regulated the ER stress - oxidative activation in retinal tissue. Also there was an improvement in the histological picture of retinal specimens compared to untreated diabetic rats. It was concluded that 4-PBA is a promising therapeutic agent for ER stress diseases such as diabetic retinopathy.Results in rowing have improved and here we estimate results for Olympic and World rowing championships based on the winning results from 1893 to 2019 obtained in the current seven Olympic events for men (n = 556) and women (n = 239). Data were collected from the official World Rowing Federation online records and from published results and the development analysed by linear regression analysis for the year of competition. Results improved by about 0.7 s per year (15 ± 9.4%) (mean ± SD). Depending on the event, 2020 predicted mean time for the winning boat for men is 363 s (range 326-397) vs. 404 s (362-439) for women (10.3 ± 1.1% slower). The ten-year coefficient of variance for the original boats in Olympic and World Rowing Federation regatta remaining within the Olympic programme, single scull and eight, decreased from 9 ± 2% (1893-1903) to 2 ± 0.4% (2009-2019). Reduced variability in winning times illustrates the standardization of the rowing course and boats, and the improvement in performance point to that body size becomes ever more important for success in competitive rowing.Strontium has been widely used in bone repair materials due to its roles in promoting osteoclast apoptosis and enhancing osteoblast proliferation. In this work, synthesis and the effects of Sr2+ doping α-tricalcium phosphate at low-temperature was studied. The setting time and the mechanical properties of α-tricalcium phosphate were controlled by varying the content of Sr2+. The synthesized compounds were evaluated by XRD, SEM, XPS, setting time, compressive strength, SBF immersion, and colorimetric CCK-8 assay. The results showed that Sr2+ can improve the compressive strength and cell activity of calcium phosphate bone cement.The present narrative review examined quantitative and qualitative research on family members who support survivors of trauma or abuse. Studies included in the present review were found in peer-reviewed journal articles, available in English, published between 1980 and 2019, and focused specifically on the experiences of adult familial supporters of adult trauma and abuse survivors. A search of PsychInfo and Google Scholar identified 136 relevant articles, and analysis of their content generated the following categories individual-level impacts (i.e., quality of psychological health, burden, secondary traumatic stress, quality of physical health, and positive impacts), interpersonal and environmental level impacts (i.e., quality of relationships with survivors, navigating environment, maltreatment and safety, and social impacts), and other experiences (i.e., social roles, needs, coping strategies, and sociocultural context). Findings indicate that the majority of existing studies examined the experiences of family members of adult survivors of military trauma.
