Effects of magnanimous therapy on coping, adjustment, and living function in advanced lung cancer.

Objectives We examined the effects of magnanimous therapy on psychological coping, adjustment, living function, and survival rate in patients with advanced lung cancer. Methods Patients with advanced lung cancer (n = 145) matched by demographics and medical variables were randomly assigned to an individual computer magnanimous therapy group (ic-mt), a group computer magnanimous therapy group (gc-mt), or a control group (ctrl). Over 2 weeks, the ic-mt and gc-mt groups received eight 40-minute sessions of ic-mt or gc-mt respectively, plus usual care; the ctrl group received only usual care. The Cancer Coping Modes Questionnaire (ccmq), the Psychological Adjustment Scale for Cancer Patients (pascp), and the Functional Living Index-Cancer (flic) were assessed at baseline and 2 weeks later. The relationships of changes in those indicators were analyzed, and survival rates were compared. Results The psychological coping style, adjustment, and living function of the ic-mt and gc-mt groups improved significantly after the intervention (p < 0.01). After 2 weeks, significant (p < 0.01) differences between the treatment groups and the ctrl group in coping style, adjustment, and living function suggested successful therapy. The changes in living function were correlated with changes in psychological coping and adjustment. No difference in efficacy between ic-mt and gc-mt was observed. The survival rate was 31.84% in the ic-mt group and 9.375% in the ctrl group at 2 years after the intervention. Conclusions In patients with advanced lung cancer, ic-mt and gc-mt were associated with positive short-term effects on psychological coping style, adjustment, and living function, although the magnitude of the effect did not differ significantly between the intervention approaches. The effects on living function are partly mediated by improvements in psychological coping and adjustment.
Reproducibility of dietary intakes of macronutrients, specific food groups, and dietary patterns in 211 050 adults in the UK Biobank study

Abstract To detect modest associations of dietary intake with disease risk, observational studies need to be large and control for moderate measurement errors. The reproducibility of dietary intakes of macronutrients, food groups and dietary patterns (vegetarian and Mediterranean) was assessed in adults in the UK Biobank study on up to five occasions using a web-based 24-h dietary assessment (n 211 050), and using short FFQ recorded at baseline (n 502 655) and after 4 years (n 20 346). When the means of two 24-h assessments were used, the intra-class correlation coefficients (ICC) for macronutrients varied from 0·63 for alcohol to 0·36 for polyunsaturated fat. The ICC for food groups also varied from 0·68 for fruit to 0·18 for fish. The ICC for the FFQ varied from 0·66 for meat and fruit to 0·48 for bread and cereals. The reproducibility was higher for vegetarian status (κ > 0·80) than for the Mediterranean dietary pattern (ICC = 0·45). Overall, the reproducibility of pairs of 24-h dietary assessments and single FFQ used in the UK Biobank were comparable with results of previous prospective studies using conventional methods. Analyses of diet–disease relationships need to correct for both measurement error and within-person variability in dietary intake in order to reliably assess any such associations with disease in the UK Biobank.
Energy flux controls tetraether lipid cyclization in Sulfolobus acidocaldarius

Microorganisms regulate the composition of their membranes in response to environmental cues. Many archaea maintain the fluidity and permeability of their membranes by adjusting the number of cyclic moieties within the cores of their glycerol dibiphytanyl glycerol tetraether (GDGT) lipids. Cyclized GDGTs increase membrane packing and stability, which has been shown to help cells survive shifts in temperature and pH. However, the extent of this cyclization also varies with growth phase and electron acceptor or donor limitation. These observations indicate a relationship between energy metabolism and membrane composition. Here we show that the average degree of GDGT cyclization increases with doubling time in continuous cultures of the thermoacidophile Sulfolobus acidocaldarius (DSM 639). This is consistent with the behavior of a mesoneutrophile, Nitrosopumilus maritimus SCM1. Together, these results demonstrate that archaeal GDGT distributions can shift in response to electron donor flux and energy availability, independent of pH or temperature. Paleoenvironmental reconstructions based on GDGTs thus capture the energy available to microbes, which encompasses fluctuations in temperature and pH, as well as electron donor and acceptor availability. The ability of Archaea to adjust membrane composition and packing may be an important strategy that enables survival during episodes of energy stress. Significance Statement Microbial lipid membranes protect and isolate a cell from its environment while regulating the flow of energy and nutrients to metabolic reaction centers within. We demonstrate that membrane lipids change as a function of energy flux using a well-studied archaeon that thrives in acidic hot springs and observe an increase in membrane packing as energy becomes more limited. These observations are consistent with chemostat experiments utilizing a low temperature, neutral pH, marine archaeon. This strategy appears to regulate membrane homeostasis is common across GDGT-producing lineages, demonstrating that diverse taxa adjust membrane composition in response to chronic energy stress.
A computerized and innovative tool to guide interdisciplinary assessment: Exploring the feasibility of the implementation of the Competency Assessment Tool (CAT)

ABSTRACT An electronic tool, the Competency Assessment Tool (CAT), was developed in order to guide interdisciplinary teams through clinical competency assessment. Objectives: To support the implementation and perpetuation of the CAT, the objectives were: 1) document health and social service professionals’ needs in order to support the use of the CAT; 2) identify the facilitating factors and those hindering the implementation of the CAT in a healthcare establishment; 3) identify strategies favoring the use of the CAT. Participants: Health and social service professionals and doctors were recruited. Methods: A qualitative study was realized by conducting focus groups with health and social service professionals and individual interviews with doctors. Results: The results allowed us to bring to light the CAT’s advantages, the issues associated with its implementation (facilitators and obstacles) and the needs to support its use. A number of avenues of intervention were identified and could be put in place to encourage the use of the CAT. Conclusion: This study will support the implementation of the CAT and ultimately, this will allow for the assurance that the decisions taken on the need for protection of vulnerable individuals will be just, rigorous and the fruit of a concerted ethical reflection.
Periodontitis and respiratory diseases: A systematic review with meta-analysis.

OBJECTIVE to conduct a systematic review and meta-analysis to evaluate the recent scientific literature addressing the association between periodontitis and asthma, chronic obstructive pulmonary disease (COPD), and pneumonia. MATERIALS AND METHODS the search for studies was carried out using MedLine/PubMed, Embase, Lilacs, Web of Science, Scopus, and SciELO databases, including the gray literature (ProQuest). Reference lists of selected articles were also searched. Studies having varying epidemiological designs assessing the association between periodontitis and respiratory diseases in humans subjects were eligible for inclusion. Three independent reviewers performed the selection of articles and data extraction. Fixed and random effects meta-analysis were performed for the calculation of the association measurements (Odds Ratio - OR) and 95% confidence intervals (95%CI). RESULTS 3,234 records were identified in the database search, with only 13 studies meeting the eligibility criteria and 10 studies contributed data for meta-analysis. Using a random effects models periodontitis was associated with asthma: ORadjusted: 3.54 (95%CI: 2.47 - 5.07), I2 = 0%, with COPD: ORadjusted: 1.78 (95%CI: 1.04 - 3.05), I2 = 37.9%, and with pneumonia: ORadjusted: 3.21 (95%CI: 1.997 - 5.17), I2 = 0%. CONCLUSIONS the main findings of this systematic review validated an association between periodontitis and asthma, COPD and pneumonia.
Executive Summary

Aim: Progress in deciphering the functionality of the human genome sequence in the wake of technological advances in the field of genomic medicine have dramatically reduced the overall costs of genetic analysis, thereby facilitating the incorporation of genetic testing services into mainstream clinical practice. Although Greek genetic testing laboratories offer a variety of different genetic tests, relatively little is known about how either the general public or medical practitioners perceive genetic testing services. Materials and Methods: We have therefore performed a nationwide survey of the views of a total of 1,717 individuals from the general public, divided in three age groups from all over Greece, and residing in large and smaller cities and villages, in order to acquire a better understanding as to how they perceive genetic testing. We also canvassed the opinions of 496 medical practitioners with regard to genetic testing services in a separate survey that addressed similar issues. Results: Our subsequent analysis indicated that a large proportion of the general public is aware of the nature of DNA, genetic disorders and the potential benefits of genetic testing, although this proportion declines steadily with age. Further, a large proportion of the interviewed sample would be willing to undergo genetic testing even if the costs of analysis were not covered by healthcare insurance. However, a relatively small proportion of the general public has actually been advised to undergo genetic testing, either by relatives or physicians. Most physicians believe that the regulatory and legal framework that governs genetic testing services in Greece is rather weak. Interestingly, the vast majority of the general public strongly opposes direct-access genetic testing, and most would prefer referral to be from a physician rather than from a pharmacist. Conclusions: Overall, our results provide a critical evaluation of the views of the general public with regard to genetics and genetic testing services in Greece and should serve as a model for replication in other populations.
Activation‐based association profiles differentiate network roles across cognitive loads

Working memory (WM) is a complex and pivotal cognitive system underlying the performance of many cognitive behaviors. Although individual differences in WM performance have previously been linked to the blood oxygenation level‐dependent (BOLD) response across several large‐scale brain networks, the unique and shared contributions of each large‐scale brain network to efficient WM processes across different cognitive loads remain elusive. Using a WM paradigm and functional magnetic resonance imaging (fMRI) from the Human Connectome Project, we proposed a framework to assess the association and shared‐association strength between imaging biomarkers and behavioral scales. Association strength is the capability of individual brain regions to modulate WM performance and shared‐association strength measures how different regions share the capability of modulating performance. Under higher cognitive load (2‐back), the frontoparietal executive control network (FPN), dorsal attention network (DAN), and salience network showed significant positive activation and positive associations, whereas the default mode network (DMN) showed the opposite pattern, namely, significant deactivation and negative associations. Comparing the different cognitive loads, the DMN and FPN showed predominant associations and globally shared‐associations. When investigating the differences in association from lower to higher cognitive loads, the DAN demonstrated enhanced association strength and globally shared‐associations, which were significantly greater than those of the other networks. This study characterized how brain regions individually and collaboratively support different cognitive loads.
Periprocedural safety and technical outcomes of the new Silk Vista Baby flow diverter for the treatment of intracranial aneurysms: results from a multicenter experience

Purpose The aim of our study was to assess the technical success and the safety of this new low-profile flow diverter Silk Vista Baby (SVB) by evaluating the intraprocedural and periprocedural complication rate. Material/methods Clinical, procedural, and angiographic data were analyzed. Results: 41 consecutive patients (28 women; age average 50.5 years) with 43 aneurysms were treated with SVB. Aneurysm sizes were classified by their maximum diameter, with an average size of 9.5 mm (range 2–30 mm). Thirty-four cases were unruptured. five aneurysms previously ruptured, had recurrence after the initial coiling. There were two ruptured cases. Aneurysms' locations were: M1 segment (five cases), M2 segment (three cases), M3 segment (one case), middle cerebral artery (MCA) bifurcation (six cases), carotid-T (two cases), anterior communicating artery/A1/A2 (11 cases), pericallosal artery (four cases), supraclinoid ICA (two cases), PCom (one case), V4 segment (three cases), PCA (three cases), SCA (one case), and PICA (one case). We had five intraprocedural complications which resolved without clinical consequences and three events postprocedural events. Initial occlusion rates were: eight aneurysms (18.6%) were completely occluded, five aneurysms (11.6%) showed near-complete occlusion, four cases (9.3%) showed incomplete filling, and 26 cases (60.4%) showed persisting filling. The mRS score at discharge from the hospital did not change from the admission mRS score. Conclusion Our study demonstrated that the use of the new low-profile flow diverter, SVB device, for the treatment of intracranial aneurysms is feasible and technically safe.
Radiative forcing of methane fluxes offsets net carbon dioxide uptake for a tropical flooded forest

Wetlands are important sources of methane (CH4) and sinks of carbon dioxide (CO2). However, little is known about CH4 and CO2 fluxes and dynamics of seasonally flooded tropical forests of South America in relation to local carbon (C) balances and atmospheric exchange. We measured net ecosystem fluxes of CH4 and CO2 in the Pantanal over 2014–2017 using tower‐based eddy covariance along with C measurements in soil, biomass and water. Our data indicate that seasonally flooded tropical forests are potentially large sinks for CO2 but strong sources of CH4, particularly during inundation when reducing conditions in soils increase CH4 production and limit CO2 release. During inundation when soils were anaerobic, the flooded forest emitted 0.11 ± 0.002 g CH4‐C m−2 d−1 and absorbed 1.6 ± 0.2 g CO2‐C m−2 d−1 (mean ± 95% confidence interval for the entire study period). Following the recession of floodwaters, soils rapidly became aerobic and CH4 emissions decreased significantly (0.002 ± 0.001 g CH4‐C m−2 d−1) but remained a net source, while the net CO2 flux flipped from being a net sink during anaerobic periods to acting as a source during aerobic periods. CH4 fluxes were 50 times higher in the wet season; DOC was a minor component in the net ecosystem carbon balance. Daily fluxes of CO2 and CH4 were similar in all years for each season, but annual net fluxes varied primarily in relation to flood duration. While the ecosystem was a net C sink on an annual basis (absorbing 218 g C m−2 (as CH4‐C + CO2‐C) in anaerobic phases and emitting 76 g C m−2in aerobic phases), high CH4 effluxes during the anaerobic flooded phase and modest CH4 effluxes during the aerobic phase indicate that seasonally flooded tropical forests can be a net source of radiative forcings on an annual basis, thus acting as an amplifying feedback on global warming.
A DNA virus-encoded immune antagonist fully masks the potent antiviral activity of RNAi in Drosophila

Significance Host immunity exerts strong selection pressure on viruses, often leading to the evolution of immune antagonists in viral genomes. In insects, this is exemplified by antiviral RNA interference (RNAi), a major antiviral defense system to which many viruses have evolved suppressor proteins. Yet, the physiological functions of viral suppressors of RNAi remain incompletely understood, as experimental systems to manipulate the viral genome of interest are often lacking. Here we generate an RNAi suppressor-defective mutant of a complex DNA virus, invertebrate iridescent virus-6. Using this mutant virus, we found that RNAi suppressor proteins can effectively and completely block the antiviral immune system of the host. Coevolution of viruses and their hosts may lead to viral strategies to avoid, evade, or suppress antiviral immunity. An example is antiviral RNA interference (RNAi) in insects: the host RNAi machinery processes viral double-stranded RNA into small interfering RNAs (siRNAs) to suppress viral replication, whereas insect viruses encode suppressors of RNAi, many of which inhibit viral small interfering RNA (vsiRNA) production. Yet, many studies have analyzed viral RNAi suppressors in heterologous systems, due to the lack of experimental systems to manipulate the viral genome of interest, raising questions about in vivo functions of RNAi suppressors. To address this caveat, we generated an RNAi suppressor-defective mutant of invertebrate iridescent virus 6 (IIV6), a large DNA virus in which we previously identified the 340R protein as a suppressor of RNAi. Loss of 340R did not affect vsiRNA production, indicating that 340R binds siRNA duplexes to prevent RNA-induced silencing complex assembly. Indeed, vsiRNAs were not efficiently loaded into Argonaute 2 during wild-type IIV6 infection. Moreover, IIV6 induced a limited set of mature microRNAs in a 340R-dependent manner, most notably miR-305–3p, which we attribute to stabilization of the miR-305–5p:3p duplex by 340R. The IIV6 340R deletion mutant did not have a replication defect in cells, but was strongly attenuated in adult Drosophila. This in vivo replication defect was completely rescued in RNAi mutant flies, indicating that 340R is a bona fide RNAi suppressor, the absence of which uncovers a potent antiviral immune response that suppresses virus accumulation ∼100-fold. Together, our work indicates that viral RNAi suppressors may completely mask antiviral immunity.
Characteristics, Risk Factors And Outcome Of Early-Onset Delirium In Elderly Patients With First Ever Acute Ischemic Stroke - A Prospective Observational Cohort Study

Introduction Post-stroke delirium is a common clinical problem, occurring in 10% to 48% of patients. It has been associated with longer hospitalization times, increased mortality and worse functional outcome. In early phase of stroke, it may be regarded as particularly difficult to differentiate from other neurological symptoms. For practical purposes, there is a need to identify simple pre-operative laboratory parameters that may aid delirium diagnosis early after stroke. Our aim was to identify the incidence of early-onset (first 24 hrs) post-stroke delirium, its risk factors and outcomes (complications and mortality) in patients with first-ever acute ischemic stroke (AIS). Material and methods A retrospective analysis of a prospective observational study (NCT03944694) was performed. Patients were screened for delirium using CAM-ICU method. Clinical and laboratory data were collected, including baseline inflammatory parameters. Results Final analysis included 760 patients, 121 (15.9%) developed delirium. Patients with delirium were older (75.9±13.5 years, p<0.001). Most common complications in the delirium group were pulmonary (57.8% vs 21.4%, p<0.001), cardiac (38.8% vs 13.6%, p<0.001) and renal (13.2% vs 7.5%, p=0.038). Neutrophil-to-lymphocyte ratio (NLR) (6.71±9.65 vs 4.55±5.51, p<0.001), C-reactive protein level (32.59±65.94 vs 15.70±38.56, p<0.001) and troponin T level (72.59±180.15 vs 26.85±77.62, p<0.001) were higher in delirious patients and platelet-to white blood cell count ratio (PWR) (23.42±9.51 vs 27.13±10.58, p<0.001) was lower. Multivariable logistic regression showed that atrial fibrillation (OR 1.651, p=0.049), higher Rankin score on admission (OR 1.689, p<0.001), hemianopia (OR 2.422, p=0.003) and PWR <20.22 (OR 2.197, p=0.002) were independently associated with delirium. Kaplan–Meier curves indicated that mortality increased for patients with delirium at 3 months (p<0.001) and 1 year (p<0.001) after AIS. Conclusion Atrial fibrillation, higher Rankin score, hemianopia and lower PWR were independently associated with early onset delirium in patients with first ever AIS. This confirms that deprivation of senses and early generalized inflammatory response are critical for delirium development.
Unraveling driving forces explaining significant reduction in satellite-inferred Arctic surface albedo since the 1980s

Significance Changes in snow cover, sea ice cover, and surface albedo over the Arctic are important for local warming and midlatitude climate change. Here, multiple datasets are used to show that observed reductions in the Arctic surface albedo in recent decades are largely linked to the decrease in Arctic snow cover fraction. The reduced snow cover fraction, driven by surface warming and declining snowfall, explains 70% of the observed reduction in the Arctic surface albedo. While absorbing aerosol (soot) falling on snow and ice can also reduce the surface albedo, the amount of soot in snow has actually been decreasing in recent decades, so soot deposition does not appear to explain the decreasing trend in snow cover and surface albedo. The Arctic has warmed significantly since the early 1980s and much of this warming can be attributed to the surface albedo feedback. In this study, satellite observations reveal a 1.25 to 1.51% per decade absolute reduction in the Arctic mean surface albedo in spring and summer during 1982 to 2014. Results from a global model and reanalysis data are used to unravel the causes of this albedo reduction. We find that reductions of terrestrial snow cover, snow cover fraction over sea ice, and sea ice extent appear to contribute equally to the Arctic albedo decline. We show that the decrease in snow cover fraction is primarily driven by the increase in surface air temperature, followed by declining snowfall. Although the total precipitation has increased as the Arctic warms, Arctic snowfall is reduced substantially in all analyzed data sets. Light-absorbing soot in snow has been decreasing in past decades over the Arctic, indicating that soot heating has not been the driver of changes in the Arctic snow cover, ice cover, and surface albedo since the 1980s.
