Estimating the costs of air pollution to the National Health Service and social care : An assessment and forecast up to 2035

BACKGROUND: Air pollution damages health by promoting the onset of some non-communicable diseases (NCDs), putting additional strain on the National Health Service (NHS) and social care. This study quantifies the total health and related NHS and social care cost burden due to fine particulate matter (PM2.5) and nitrogen dioxide (NO2) in England. METHOD AND FINDINGS: Air pollutant concentration surfaces from land use regression models and cost data from hospital admissions data and a literature review were fed into a microsimulation model, that was run from 2015 to 2035. Different scenarios were modelled: (1) baseline 'no change' scenario; (2) individuals' pollutant exposure is reduced to natural (non-anthropogenic) levels to compute the disease cases attributable to PM2.5 and NO2; (3) PM2.5 and NO2 concentrations reduced by 1 μg/m3; and (4) NO2 annual European Union limit values reached (40 μg/m3). For the 18 years after baseline, the total cumulative cost to the NHS and social care is estimated at £5.37 billion for PM2.5 and NO2 combined, rising to £18.57 billion when costs for diseases for which there is less robust evidence are included. These costs are due to the cumulative incidence of air-pollution-related NCDs, such as 348,878 coronary heart disease cases estimated to be attributable to PM2.5 and 573,363 diabetes cases estimated to be attributable to NO2 by 2035. Findings from modelling studies are limited by the conceptual model, assumptions, and the availability and quality of input data. CONCLUSIONS: Approximately 2.5 million cases of NCDs attributable to air pollution are predicted by 2035 if PM2.5 and NO2 stay at current levels, making air pollution an important public health priority. In future work, the modelling framework should be updated to include multi-pollutant exposure-response functions, as well as to disaggregate results by socioeconomic status

Immune and nonimmune predictors of cardiac allograft vasculopathy onset and severity: multivariate risk factor analysis and role of immunosuppression.

We studied 361 patients, to evaluate risk factors for cardiac allograft vasculopathy (CAV) onset and severity/diffusion in heart transplantation (HT). Rejection scores (RS) on endomyocardial biopsy were calculated (first year and whole follow-up). CAV onset was defined as any lesion seen at yearly angiography. A CAV severity/diffusion index was calculated for each patient summing up the scores of all lesions. Cox multivariate analysis included: donor age, sex, and weight; recipient sex, age, pre-HT diagnosis, hypertension, diabetes and hyperlipidemia post-HT; number of treated rejections and RS; and immunosuppressive dosage at 3, 6, and 12 months. CAV frequency was 2% at 1 year, 22% at 5 and 39% at 10 years. Risk factors for CAV onset were older donor age [p or = 3A) grades (p < 0.02, RR = 2.01), high cyclosporine at 3 months (p < 0.02, RR = 1.9). Risk factors for CAV severity/diffusion were higher donor weight (p < 0.01, RR = 7.5), high prednisone dosage at 1 year (p < 0.0001, RR = 21.1), and coronary disease pre-HT (p < 0.002, RR = 9.7). High RS was an independent predictor for CAV onset, not severity/diffusion. This suggests an immune basis for CAV onset and nonimmune modulation for progression. High RS for severe grades may provide a predictor for patients at risk

Abnormal total ejection isovolume index as early noninvasive marker of chronic rejection in heart transplantation

Abnormally high myocardial performance index (MPI) is a Doppler-derived marker of combined systolic and diastolic left ventricular (LV) dysfunction. To identify early stage allograft dysfunction by MPI, we studied 154 long-term heart transplantation (HT) recipients (131 male, aged 51 +/- 13 years at HT, mean follow up 8.4 +/- 3.5 years), with normal left ventricular ejection fraction (LVEF) and free from acute rejection (AR), and 25 normals (13 male, aged 39 +/- 16 years). Rejection score (RS) on endomyocardial biopsy was calculated in the first year. MPI was prolonged (0.45 +/- 0.18 vs. 0.28 +/- 0.10, P = 0.0001) in patients and directly related with mean time from HT (P = 0.001), higher cumulative dosages of cyclosporine at 3 months (P = 0.01), 6 months (P = 0.03), 1 year (P = 0.02), 3 years (P = 0.04) and with cumulative dosage of methylprednisolone at 1 year (P = 0.002). The index was inversely related with mean age at HT (P = 0.002) and tended to be directly related with RS at 1 year (P = 0.05). Thus, MPI is abnormal in long-term HT recipients with normal LVEF. Its direct relation with time from HT as well as immunosuppressive load suggests an early stage of graft dysfunction because of chronic rejection. Extended prospective studies are warranted to clarify its potential role as a negative prognostic marker in HT

COVID 19-associated chilblain-like acral lesions among children and adolescents: an Italian retrospective, multicenter study

BACKGROUND: Since the COVID-19 pandemic started, great interest has been given to this disease, especially to its possible clinical presentations. Besides classical respiratory symptoms, dermatological manifestations occur quite often among infected and non-infected patients, particularly in children. A prominent IFN-I response, that is generally higher in children compared to adults, may not only cause chilblain lesions, but it could also prevent infection and viral replication, thus justifying the negative swab results, as well as the absence of relevant systemic symptoms in positive cases. Indeed, reports have emerged describing chilblain-like acral lesions in children and adolescents with either proven or suspected infection. METHODS: Patients aged from 1 to 18 years old were enrolled in this study from 23 Italian dermatological units and were observed for an over-all period of 6 months. Clinical pictures were collected along with data on the location and duration of skin lesions, their association with con-comitant local and systemic symptoms, presence of nail and/or mucosal involvement, as well as histological, laboratory and imaging findings. RESULTS: One hundred thirty-seven patients were included, of whom 56.9% were females. Mean age was 11.97 &amp; PLUSMN;3.66 years. The most com-monly affected sites were the feet (77 patients, 56.2%). Lesions (48.5%) featured cyanosis, chilblains, blisters, ecchymosis, bullae, erythema, edema, and papules. Concomitant skin manifestations included maculo-papular rashes (30%), unspecified rashes (25%), vesicular rashes (20%), erythema multiforme (10%), urticaria (10%) and erythema with desquamation (5%). Forty-one patients (29.9%) reported pruritus as the main symptom associated with chilblains, and 56 out of 137 patients also reported systemic symptoms such as respiratory symptoms (33.9%), fever (28%), intestinal (27%), headache (5.5%), asthenia (3.5%), and joint pain (2%). Associated comorbid conditions were observed in 9 patients presenting with skin lesions. Nasopharyngeal swabs turned out positive in 11 patients (8%), whereas the remainder were either negative (101, 73%) or unspecified (25, 18%). CONCLUSIONS: COVID-19 has been credited as the etiology of the recent increase in acro-ischemic lesions. The present study provides a description of pediatric cutaneous manifestations deemed to be potentially associated with COVID-19, revealing a possible association between acral cyanosis and nasopharyngeal swab positivity in children and teenagers. The identification and characterization of newly recognized pat-terns of skin involvement may aid physicians in diagnosing cases of asymptomatic or pauci-symptomatic COVID patients

The EASL-Lancet Liver Commission: protecting the next generation of Europeans against liver disease complications and premature mortality

Liver diseases have become a major health threat across Europe, and the face of European hepatology is changing due to the cure of viral hepatitis C and the control of chronic viral hepatitis B, the increasingly widespread unhealthy use of alcohol, the epidemic of obesity, and undiagnosed or untreated liver disease in migrant populations. Consequently, Europe is facing a looming syndemic, in which socioeconomic and health inequities combine to adversely affect liver disease prevalence, outcomes, and opportunities to receive care. In addition, the COVID-19 pandemic has magnified pre-existing challenges to uniform implementation of policies and equity of access to care in Europe, arising from national borders and the cultural and historical heterogeneity of European societies. In following up on work from the Lancet Commission on liver disease in the UK and epidemiological studies led by the European Association for the Study of the Liver (EASL), our multidisciplinary Commission, comprising a wide range of public health, medical, and nursing specialty groups, along with patient representatives, set out to provide a snapshot of the European landscape on liver diseases and to propose a framework for the principal actions required to improve liver health in Europe. We believe that a joint European process of thinking, and construction of uniform policies and action, implementation, and evaluation can serve as a powerful mechanism to improve liver care in Europe and set the way for similar changes globally. On the basis of these data, we present ten actionable recommendations, half of which are oriented towards health-care providers and half of which focus primarily on health policy. A fundamental shift must occur, in which health promotion, prevention, proactive casefinding, early identification of progressive liver fibrosis, and early treatment of liver diseases replace the current emphasis on the management of end-stage liver disease complications. A considerable focus should be put on underserved and marginalised communities, including early diagnosis and management in children, and we provide proposals on how to better target disadvantaged communities through health promotion, prevention, and care using multilevel interventions acting on current barriers. Underlying this transformative shift is the need to enhance awareness of the preventable and treatable nature of many liver diseases. Therapeutic nihilism, which is prevalent in current clinical practice across a range of medical specialities as well as in many patients themselves, has to end. We wish to challenge medical specialty protectionism and invite a broad range of stakeholders, including primary care physicians, nurses, patients, peers, and members of relevant communities, along with medical specialists trained in obesity, diabetes, liver disease, oncology, cardiovascular disease, public health, addictions, infectious diseases, and more, to engage in integrated person-centred liver patient care across classical medical specialty boundaries. This shift includes a revision in how we converse about liver disease and speak with our patients, and a reappraisal of disease-related medical nomenclature conducted to increase awareness and reduce the social stigmatisation associated with liver disease. Reimbursement mechanisms and insurance systems must be harmonised to account for patient-centric, multimorbidity models of care across a range of medical specialties, and the World Health Assembly resolution to improve the transparency and fairness of market prices for medicines throughout Europe should be reinforced. Finally, we outline how Europe can move forward with implementation of effective policy action on taxation, food reformulation, and product labelling, advertising, and availability, similar to that implemented for tobacco, to reduce consumption of alcohol, ultraprocessed foods, and foods with added sugar, especially among young people. We should utilise the window of opportunity created by the COVID-19 pandemic to overcome fragmentation and the variability of health prevention policies and research across Europe. We argue that the liver is a window to the 21st-century health of the European population. Through our proposed syndemic approach to liver disease and social and health inequities in Europe, the liver will serve as a sentinel for improving the overall health of European populations
