It has been claimed that we are ‘all in it together’ and that the COVID-19 virus ‘does not discriminate’.
This accessible, yet authoritative book dispels this myth of COVID-19 as an ‘equal opportunity’ disease, by showing how the pandemic is a syndemic of disease and inequality.
Drawing on international data and accounts, it argues that the pandemic is unequal in three ways: it has killed unequally, been experienced unequally and will impoverish unequally.
These inequalities are a political choice: with governments effectively choosing who lives and who dies, we need to learn from COVID-19 quickly to prevent growing inequality and to reduce health inequalities in the future.
COVID-19 is an unequal pandemic.
The roots of most plants are colonized by symbiotic fungi to form mycorrhiza, which play a critical role in the capture of nutrients from the soil and therefore in plant nutrition. Mycorrhizal ...Symbiosis is recognized as the definitive work in this area. Since the last edition was published there have been major advances in the field, particularly in the area of molecular biology, and the new edition has been fully revised and updated to incorporate these exciting new developments.
. Over 50% new material. Includes expanded color plate section. Covers all aspects of mycorrhiza. Presents new taxonomy. Discusses the impact of proteomics and genomics on research in this area
Since the late Pleistocene, large-bodied mammals have been extirpated from much of Earth. Although all habitable continents once harbored giant mammals, the few remaining species are largely confined ...to Africa. This decline is coincident with the global expansion of hominins over the late Quaternary. Here, we quantify mammalian extinction selectivity, continental body size distributions, and taxonomic diversity over five time periods spanning the past 125,000 years and stretching approximately 200 years into the future. We demonstrate that size-selective extinction was already under way in the oldest interval and occurred on all continents, within all trophic modes, and across all time intervals. Moreover, the degree of selectivity was unprecedented in 65 million years of mammalian evolution. The distinctive selectivity signature implicates hominin activity as a primary driver of taxonomic losses and ecosystem homogenization. Because megafauna have a disproportionate influence on ecosystem structure and function, past and present body size downgrading is reshaping Earth's biosphere.
Cerebrovascular and cardiovascular diseases cause vascular brain injury that can lead to vascular cognitive impairment (VCI). VCI is the second most common neuropathology of dementia and mild ...cognitive impairment (MCI), accounting for up to one-third of the population risk. It is frequently present along with other age-related pathologies such as Alzheimer's disease (AD). Multiple etiology dementia with both VCI and AD is the single most common cause of later life dementia. There are two main clinical syndromes of VCI: post-stroke VCI in which cognitive impairment is the immediate consequence of a recent stroke and VCI without recent stroke in which cognitive impairment is the result of covert vascular brain injury detected only on neuroimaging or neuropathology. VCI is a syndrome that can result from any cause of infarction, hemorrhage, large artery disease, cardioembolism, small vessel disease, or other cerebrovascular or cardiovascular diseases. Secondary prevention of further vascular brain injury may improve outcomes in VCI.
Organic electrochemical transistors (OECTs) are presently a focus of intense research and hold great potential in expanding the horizons of the bioelectronics industry. The notable characteristics of ...OECTs, including their electrolyte‐gating, which offers intimate interfacing with biological environments, and aqueous stability, make them particularly suitable to be operated within a living organism (in vivo). Unlike the existing in vivo bioelectronic devices, mostly based on rigid metal electrodes, OECTs form a soft mechanical contact with the biological milieu and ensure a high signal‐to‐noise ratio because of their powerful amplification capability. Such features make OECTs particularly desirable for a wide range of in vivo applications, including electrophysiological recordings, neuron stimulation, and neurotransmitter detection, and regulation of plant processes in vivo. In this review, a systematic compilation of the in vivo applications is presented that are addressed by the OECT technology. First, the operating mechanisms, and the device design and materials design principles of OECTs are examined, and then multiple examples are provided from the literature while identifying the unique device properties that enable the application progress. Finally, one critically looks at the future of the OECT technology for in vivo bioelectronic applications.
The role of organic electrochemical transistors in different in vivo bioelectronic applications, ranging from human electrophysiology to plant interfacing, is discussed. Particular emphasis is given on analyzing the key materials design and device design aspects that make these devices ideal for addressing future in vivo biological systems. Finally, some challenges, limitations, and future applications are critically assessed.
•Analysis of pro-climate behavior and policy support in 35 nations.•We test for a “social trap” where lack of trust blunts the effect of perceived risk.•At both the individual and national level, ...risk and trust are important predictors.•Inconsistent interaction between trust and risk perception.•A “thin social trap” may exist for social trust for policy support, but not behaviors.
Climate change presents a global problem that requires a collective, coordinated response to reduce the rate of greenhouse gases currently emitted. But, even in the face of these serious growing dangers, behavioral and policy responses have been rather muted. A growing literature has documented cross-national differences in climate change attitudes and related scholarship has analyzed general environmental concern across nations. Yet there are several holes in our knowledge. In this manuscript, we consider the role of trust, risk perceptions and investigate the possibility of a “social trap” (Rothstein, 2005) whereby a lack of trust blunts the effect of risk perceptions on public willingness to engage in behaviors or support policies to address climate change. Using between- and within- random effects models coupled with survey data from 35 countries, we find that, at the individual level, trust and risk perceptions are generally positively associated with ameliorative behavior and policy support. Results for a contextual effect of trust and risk perceptions are more mixed, and we find only slim support for an interactive relationship between trust and risk perceptions.
Pelvic floor muscle training (PFMT) is the most commonly used physical therapy treatment for women with stress urinary incontinence (SUI). It is sometimes also recommended for mixed urinary ...incontinence (MUI) and, less commonly, urgency urinary incontinence (UUI).This is an update of a Cochrane Review first published in 2001 and last updated in 2014.
To assess the effects of PFMT for women with urinary incontinence (UI) in comparison to no treatment, placebo or sham treatments, or other inactive control treatments; and summarise the findings of relevant economic evaluations.
We searched the Cochrane Incontinence Specialised Register (searched 12 February 2018), which contains trials identified from CENTRAL, MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, ClinicalTrials.gov, WHO ICTRP, handsearching of journals and conference proceedings, and the reference lists of relevant articles.
Randomised or quasi-randomised controlled trials in women with SUI, UUI or MUI (based on symptoms, signs or urodynamics). One arm of the trial included PFMT. Another arm was a no treatment, placebo, sham or other inactive control treatment arm.
At least two review authors independently assessed trials for eligibility and risk of bias. We extracted and cross-checked data. A third review author resolved disagreements. We processed data as described in the Cochrane Handbook for Systematic Reviews of Interventions. We subgrouped trials by diagnosis of UI. We undertook formal meta-analysis when appropriate.
The review included 31 trials (10 of which were new for this update) involving 1817 women from 14 countries. Overall, trials were of small-to-moderate size, with follow-ups generally less than 12 months and many were at moderate risk of bias. There was considerable variation in the intervention's content and duration, study populations and outcome measures. There was only one study of women with MUI and only one study with UUI alone, with no data on cure, cure or improvement, or number of episodes of UI for these subgroups.Symptomatic cure of UI at the end of treatment: compared with no treatment or inactive control treatments, women with SUI who were in the PFMT groups were eight times more likely to report cure (56% versus 6%; risk ratio (RR) 8.38, 95% confidence interval (CI) 3.68 to 19.07; 4 trials, 165 women; high-quality evidence). For women with any type of UI, PFMT groups were five times more likely to report cure (35% versus 6%; RR 5.34, 95% CI 2.78 to 10.26; 3 trials, 290 women; moderate-quality evidence).Symptomatic cure or improvement of UI at the end of treatment: compared with no treatment or inactive control treatments, women with SUI who were in the PFMT groups were six times more likely to report cure or improvement (74% versus 11%; RR 6.33, 95% CI 3.88 to 10.33; 3 trials, 242 women; moderate-quality evidence). For women with any type of UI, PFMT groups were two times more likely to report cure or improvement than women in the control groups (67% versus 29%; RR 2.39, 95% CI 1.64 to 3.47; 2 trials, 166 women; moderate-quality evidence).UI-specific symptoms and quality of life (QoL) at the end of treatment: compared with no treatment or inactive control treatments, women with SUI who were in the PFMT group were more likely to report significant improvement in UI symptoms (7 trials, 376 women; moderate-quality evidence), and to report significant improvement in UI QoL (6 trials, 348 women; low-quality evidence). For any type of UI, women in the PFMT group were more likely to report significant improvement in UI symptoms (1 trial, 121 women; moderate-quality evidence) and to report significant improvement in UI QoL (4 trials, 258 women; moderate-quality evidence). Finally, for women with mixed UI treated with PFMT, there was one small trial (12 women) reporting better QoL.Leakage episodes in 24 hours at the end of treatment: PFMT reduced leakage episodes by one in women with SUI (mean difference (MD) 1.23 lower, 95% CI 1.78 lower to 0.68 lower; 7 trials, 432 women; moderate-quality evidence) and in women with all types of UI (MD 1.00 lower, 95% CI 1.37 lower to 0.64 lower; 4 trials, 349 women; moderate-quality evidence).Leakage on short clinic-based pad tests at the end of treatment: women with SUI in the PFMT groups lost significantly less urine in short (up to one hour) pad tests. The comparison showed considerable heterogeneity but the findings still favoured PFMT when using a random-effects model (MD 9.71 g lower, 95% CI 18.92 lower to 0.50 lower; 4 trials, 185 women; moderate-quality evidence). For women with all types of UI, PFMT groups also reported less urine loss on short pad tests than controls (MD 3.72 g lower, 95% CI 5.46 lower to 1.98 lower; 2 trials, 146 women; moderate-quality evidence).Women in the PFMT group were also more satisfied with treatment and their sexual outcomes were better. Adverse events were rare and, in the two trials that did report any, they were minor. The findings of the review were largely supported by the 'Summary of findings' tables, but most of the evidence was downgraded to moderate on methodological grounds. The exception was 'participant-perceived cure' in women with SUI, which was rated as high quality.
Based on the data available, we can be confident that PFMT can cure or improve symptoms of SUI and all other types of UI. It may reduce the number of leakage episodes, the quantity of leakage on the short pad tests in the clinic and symptoms on UI-specific symptom questionnaires. The authors of the one economic evaluation identified for the Brief Economic Commentary reported that the cost-effectiveness of PFMT looks promising. The findings of the review suggest that PFMT could be included in first-line conservative management programmes for women with UI. The long-term effectiveness and cost-effectiveness of PFMT needs to be further researched.
Root systems of most land plants form arbuscular mycorrhizal (AM) symbioses in the field, and these contribute to nutrient uptake. AM roots have two pathways for nutrient absorption, directly through ...the root epidermis and root hairs and via AM fungal hyphae into root cortical cells, where arbuscules or hyphal coils provide symbiotic interfaces. New physiological and molecular evidence shows that for phosphorus the mycorrhizal pathway (MP) is operational regardless of plant growth responses (positive or negative). Amounts delivered cannot be determined from plant nutrient contents because when responses are negative the contribution of the direct pathway (DP) is reduced. Nitrogen (N) is also delivered to roots via an MP, but the contribution to total N requirement and the costs to the plant are not clear. The functional interplay between activities of the DP and MP has important implications for consideration of AM symbioses in ecological, agronomic, and evolutionary contexts.
