NH3 gas transport and uptake pathways may be fundamentally different from those of more commonly studied soil N species and warrant further research.Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a global pandemic that has spread all over the word. To avoid the virus transmission, healthcare workers must wear adequate personal protective equipment (PPE). PPE is associated with several side events, including skin reactions. The objective of this study was to summarize the prevalence, type and risk factors for cutaneous adverse events related to PPE and prevention measures to avoid them. A systematic review and meta-analysis was conducted using MEDLINE, Scopus and EMBASE databases from conception to 21 January 2021. All types of epidemiological studies regarding skin adverse events related to PPE were included. The literature search identified 1007 references, 35 of them met the eligible criteria and were included for analysis, representing 31 453 participants. The media of skin side events related to PPE was 75.13%. The rate of cutaneous adverse events related to mask was 57.71%, and those associated with gloves and hand hygiene products was 49.16%. Most common skin adverse events were contact dermatitis, acne and itching. The most damaged anatomical regions were the nasal bridge, the cheeks and the hands. The duration of PPE wearing was the most common risk factor. Frequent handwashing, gloves and masks were the agents most frequently related to skin reactions. N95 respirators were the most harmful mask type for the skin. Hydrocolloid use prevented from developing skin adverse events related to masks. In conclusion, the rate of cutaneous adverse events related to PPE use is high. A longer duration of PPE wearing was the most common risk factor. Using hydrocolloid could prevent from skin injuries related to mask use. The potential to compute volume metrics of emphysema from planar scout images was investigated in this study. The successful implementation of this concept will have a wide impact in different fields, and specifically, maximize the diagnostic potential of the planar medical images. We investigated our premise using a well-characterized chronic obstructive pulmonary disease (COPD) cohort. In this cohort, planar scout images from computed tomography (CT) scans were used to compute lung volume and percentage of emphysema. Lung volume and percentage of emphysema were quantified on the volumetric CT images and used as the "ground truth" for developing the models to compute the variables from the corresponding scout images. We trained two classical convolutional neural networks (CNNs), including VGG19 and InceptionV3, to compute lung volume and the percentage of emphysema from the scout images. The scout images (n=1,446) were split into three subgroups (1) training (n=1,235), (2) internal validation (n=99), and (3) independent test (n=112) at the subject level in a ratio of 811. selleck chemicals The mean absolute difference (MAD) and R-square (R2) were the performance metrics to evaluate the prediction performance of the developed models. The lung volumes and percentages of emphysema computed from a single planar scout image were significantly linear correlated with the measures quantified using volumetric CT images (VGG19 R2=0.934 for lung volume and R2=0.751 for emphysema percentage, and InceptionV3 R2=0.977 for lung volume and R2=0.775 for emphysema percentage). The mean absolute differences (MADs) for lung volume and percentage of emphysema were 0.302±0.247L and 2.89±2.58%, respectively, for VGG19, and 0.366±0.287L and 3.19±2.14, respectively, for InceptionV3. Our promising results demonstrated the feasibility of inferring volume metrics from planar images using CNNs.Our promising results demonstrated the feasibility of inferring volume metrics from planar images using CNNs. Advance care planning (ACP) is critically important for heart failure patients, yet important challenges exist. Group visits can be a helpful way to engage patients and caregivers in identifying values and preferences for future care in a resource-efficient way. We sought to evaluate the impact of group visits for ACP among older adults with heart failure and their caregivers on ACP-related outcomes. We conducted a mixed-methods pilot study evaluating the impact of an ACP group visit for older adults with heart failure and their caregivers on ACP-related outcomes including readiness and self-efficacy. The evidence-based PREPARE for Your Care video-based intervention was used to guide the group visits. Twenty patients and 10 caregivers attended one of the five 90-min group visits led by a trained facilitator. Group visit participants completed pre-, post-, and 1-month follow-up surveys using validated 5-point ACP readiness and self-efficacy scales. Qualitative feedback obtained within 3 days of a group vissease-focused group visits may have a short-term effect on ACP outcomes but ongoing touchpoints are likely necessary to sustain ACP over time. The results highlight a need for follow-up ACP conversations after a single group visit. Timing for follow-ups and the ideal person to follow-up ACP conversations needs to be explored.Plasmacytoid dendritic cells (pDCs) play a key role in the initiation and amplification of systemic lupus erythematosus (SLE)-associated vascular injury. In this study, we found that dsDNA induced dose- and time-dependent increase in IFN-α and Toll-like receptor 7 (TLR7), TLR9 and IRF7 expression in pDCs. Co-cultured circulating endothelial cells (ECs) with activated pDCs significantly decreased proliferation, tube formation and migration in ECs. The elevated level of cellular IFN-α increased cell adhesion, promoted cell apoptosis, induced cell senescence and arrested cells at G0/G1 phase of endothelial progenitor cells (EPCs). Additionally, the co-culture system activated MAPK and inactivated PI3K. Pristane was used to establish a in vivo SLE-like mouse model. Importantly, we showed that INF-α-neutralizing antibody (IFN-α-NA) rescued all the changes induced by IFN-α in vitro and prevented vascular injury in pristane-induced SLE model in vivo. In conclusion, we confirmed that activated pDCs promoted vascular damage and the dysfunction of ECs/EPCs via IFN-α production.
