Association between swallowing dynamics, tongue pressure and pulmonary function in patients with idiopathic pulmonary fibrosis.

BACKGROUND: Swallowing is a complex process that requires the coordination of muscles in the mouth, pharynx, larynx, and esophagus. Dysphagia occurs when a person has difficulty swallowing. In the case of subjects with respiratory diseases, the presence of oropharyngeal dysphagia potentially increases lung disease exacerbations, which can lead to a rapid decline in lung function. This study aimed to analyze the swallowing of patients with idiopathic pulmonary fibrosis (IPF). METHODS: Patients with IPF were evaluated using the Eating Assessment Tool (EAT-10), tongue pressure, the Timed Water Swallow Test (TWST), and the Test of Mastication and Swallowing Solids (TOMASS). The findings were related to dyspnea severity assessed by the modified Medical Research Counsil (mMRC) score; the nutritional status screened with Mini Nutritional Assessment (MNA) tool; and pulmonary function tests, specifically spirometry and measurement of the diffusing capacity for carbon monoxide (DLCO), the maximal inspiratory pressure (PImax), and the maximal expiratory pressure (PEmax). RESULTS: The sample consisted of 34 individuals with IPF. Those who exhibited swallowing modifications scored lower on the MNA than those who did not (9.6 ± 0.76 vs. 11.64 ± 0.41 points; mean difference 1.98 ± 0.81 points; p = 0.02). They also showed poorer lung function when considering the predicted force vital capacity (FVC; 81.5% ± 4.61% vs. 61.87% ± 8.48%; mean difference 19.63% ± 9.02%; p = 0.03). The speed of liquid swallowing was altered in 31of 34 of the evaluated subjects (91.1%). The number of liquid swallows correlated significantly with the forced expiratory volume in 1 s (FEV1)/FVC ratio (r = 0.3; p = 0.02). Solid eating and swallowing assessed with the TOMASS score correlated with lung function. The number of chewing cycles correlated negatively with PImax% predicted (r = -0.4; p = 0.0008) and PEmax% predicted (r = -0.3; p = 0.02). FVC% predicted correlated with increased solid swallowing time (r = -0.3; p = 0.02; power = 0.6). Swallowing solids was also impacted by dyspnea. CONCLUSION: Patients with mild-to-moderate IPF can present feeding adaptations, which can be related to the nutritional status, lung function, and the severity of dyspnea.

Inequality in mortality between Black and White Americans by age, place, and cause and in comparison to Europe, 1990 to 2018.

Although there is a large gap between Black and White American life expectancies, the gap fell 48.9% between 1990 and 2018, mainly due to mortality declines among Black Americans. We examine age-specific mortality trends and racial gaps in life expectancy in high- and low-income US areas and with reference to six European countries. Inequalities in life expectancy are starker in the United States than in Europe. In 1990, White Americans and Europeans in high-income areas had similar overall life expectancy, while life expectancy for White Americans in low-income areas was lower. However, since then, even high-income White Americans have lost ground relative to Europeans. Meanwhile, the gap in life expectancy between Black Americans and Europeans decreased by 8.3%. Black American life expectancy increased more than White American life expectancy in all US areas, but improvements in lower-income areas had the greatest impact on the racial life expectancy gap. The causes that contributed the most to Black Americans' mortality reductions included cancer, homicide, HIV, and causes originating in the fetal or infant period. Life expectancy for both Black and White Americans plateaued or slightly declined after 2012, but this stalling was most evident among Black Americans even prior to the COVID-19 pandemic. If improvements had continued at the 1990 to 2012 rate, the racial gap in life expectancy would have closed by 2036. European life expectancy also stalled after 2014. Still, the comparison with Europe suggests that mortality rates of both Black and White Americans could fall much further across all ages and in both high-income and low-income areas.

Bladder Stones in Renal Transplant Patients: Presentation, Management, and Follow-up.

INTRODUCTION: The study aim was to analyze the presentation, management, and follow-up of renal transplant patients developing bladder calculi. METHODS: Patients who underwent renal transplant with postoperative follow-up at our institution were retrospectively analyzed (1984-2023) to assess for the development of posttransplant bladder stones. All bladder stones were identified by computerized tomography imaging and stone size was measured using this imaging modality. RESULTS: The prevalence of bladder calculi post-renal transplantation during the study window was 0.22% (N = 20/8,835) with a median time to bladder stone diagnosis of 13 years posttransplant. Of all bladder stone patients, 6 (30%) received deceased donor and 14 (70%) living donor transplants. There were 11 patients with known bladder stone composition available; the most common being calcium oxalate (N = 6). Eleven (55%) patients had clinical signs or symptoms (most commonly microhematuria). Fourteen of the bladder stone cohort patients (70%) underwent treatment including cystolitholapaxy in 12 subjects. Of these 14 patients, 9 (64%) were found to have nonabsorbable suture used for their ureteroneocystostomy closure. CONCLUSIONS: The prevalence of bladder stones post-renal transplant is low. The utilization of nonabsorbable suture for ureteral implantation was the main risk factor identified in our series. This technique is no longer used at our institution. Other factors contributing to bladder stone formation in this population warrant identification.

Physical activity levels, cardiovascular risk, and self-perceived barrier to physical activity in people living with HIV in Maranhão, Brazil: a short report.

The aim of this research was to investigate the existence of associations between habitual physical activity and cardiovascular risk in people living with HIV; and to identify self-perceived barriers to physical activity. The sample of 104 subjects was composed of people living with HIV and treatment for at least 6 months in a Specialized Care Service. Baeck's survey, a self-perceived barrier questionnaire, medical records, and equations from Framingham's Cardiovascular Disease were used. Linear regression models were used to investigate the association between Habitual Physical Activity score (HPA) and predicted cardiovascular risk, and descriptive statistics to investigate prevalence of self-perceived barriers. In the first model (r² = 0.212, F = 4.34, p < 0.001), increasing 1 point in the HPA score predicts the decrease by 1.04 percentage points (p.p.) Cardiovascular risk for the next 10 years. In the second model (r2 = 0. 244, F = 4. 99, p < 0.001), increase one point the HPA score decreases by 3.729 p.p. Predicted cardiovascular risk for the next 30 years. The results confirmed an inverse association between HPA and predicted cardiovascular risk in PLHIV.

Acute kidney injury in autologous hematopoietic stem cell transplant for patients with lymphoma - KDIGO classification with creatinine and urinary output criteria: a cohort analysis.

Eligibility and indication for autologous hematopoietic stem cell transplantation (HSCT) in patients with lymphoma are increasing. Acute kidney injury (AKI) is a known complication of HSCT with studies including a miscellaneous of hematological diagnoses and using different definitions of AKI. We aimed to evaluate incidence, risk factors and prognostic impact of AKI post-HSCT in patients with lymphoma submitted to autologous HSCT using the KDIGO classification with both serum creatinine and urinary output criteria. We performed a single-center retrospective cohort study including patients with lymphoma admitted for autologous HSCT. We used survival analysis with competing risks to evaluate cumulative incidence of AKI, AKI risk factors and AKI impact on disease-free survival. We used Cox regression for impact of AKI on overall survival. We used backward stepwise regression to create multivariable models. A total of 115 patients were included. Cumulative incidence of AKI: 63.7% 100 d post-HSCT. First diagnosis criteria: creatinine in 54.8%, urinary output in 41.1% and both in 4.1%. AKI highest stage: 1 in 57.5%, 2 in 17.8% and 3 in 24.7%. Variables independently associated with higher incidence of AKI were: use of nephrotoxic drugs (HR: 2.87, 95% CI: 1.07-7.65; p = 0.035), mucositis (HR: 1.95, 95% CI: 1.16-3.29; p = 0.012) and shock (HR: 2.63, 95% CI: 1.19-5.85; p = 0.017). Moderate to severe AKI was independently associated with lower overall survival (HR: 2.04, 95% CI: 1.06-3.94; p = 0.033). No association with relapse nor progression to chronic kidney disease (CKD) was found. AKI affects almost two thirds of patients with lymphomas submitted to autologous HSCT. Nephrotoxic drugs, mucositis and shock are important independent AKI risk factors. More than one third of AKI episodes are moderate to severe and these are associated with lower overall survival.

C-reactive protein-to-albumin ratio and six-month mortality in incident hemodialysis patients.

BACKGROUND: The first few months of hemodialysis (HD) are associated with a higher risk of mortality. Protein-energy malnutrition is a demonstrated major risk factor for mortality in this population. The C-Reactive Protein to Albumin ratio (CAR) has also been associated with increased mortality risk. The aim of this study was to determine the predictive value of CAR for six-month mortality in incident HD patients. METHODS: Retrospective analysis of incident HD patients between January 2014 and December 2019. CAR was calculated at the start of HD. We analyzed six-month mortality. A Cox regression was performed to predict six-month mortality and the discriminatory ability of CAR was determined using the receiver operating characteristic (ROC) curve. RESULTS: A total of 787 patients were analyzed (mean age 68.34 ± 15.5 years and 60.6% male). The 6-month mortality was 13.8% (n = 109). Patients who died were significantly older (p < 0.001), had more cardiovascular disease (p = 0.010), had central venous catheter at the start of HD (p < 0.001), lower parathyroid hormone (PTH) level (p = 0.014) and higher CAR (p = 0.015). The AUC for mortality prediction was 0.706 (95% CI (0.65-0.76), p < 0.001). The optimal CAR cutoff was ≥0.5, HR 5.36 (95% CI 3.21-8.96, p < 0.001). CONCLUSION: We demonstrated that higher CAR was significantly associated with a higher mortality risk in the first six months of HD, highlighting the prognostic importance of malnutrition and inflammation in patients starting chronic HD.

COPD Patients Exhibit Distinct Gene Expression, Accelerated Cellular Aging, and Bias to M2 Macrophages.

COPD, one of world's leading contributors to morbidity and mortality, is characterized by airflow limitation and heterogeneous clinical features. Three main phenotypes are proposed: overlapping asthma/COPD (ACO), exacerbator, and emphysema. Disease severity can be classified as mild, moderate, severe, and very severe. The molecular basis of inflammatory amplification, cellular aging, and immune response are critical to COPD pathogenesis. Our aim was to investigate EP300 (histone acetylase, HAT), HDAC 2 (histone deacetylase), HDAC3, and HDAC4 gene expression, telomere length, and differentiation ability to M1/M2 macrophages. For this investigation, 105 COPD patients, 42 smokers, and 73 non-smoker controls were evaluated. We identified a reduced HDAC2 expression in patients with mild, moderate, and severe severity; a reduced HDAC3 expression in patients with moderate and severe severity; an increased HDAC4 expression in patients with mild severity; and a reduced EP300 expression in patients with severe severity. Additionally, HDAC2 expression was reduced in patients with emphysema and exacerbator, along with a reduced HDAC3 expression in patients with emphysema. Surprisingly, smokers and all COPD patients showed telomere shortening. COPD patients showed a higher tendency toward M2 markers. Our data implicate genetic changes in COPD phenotypes and severity, in addition to M2 prevalence, that might influence future treatments and personalized therapies.

Copy number variations in a Brazilian cohort with autism spectrum disorders highlight the contribution of cell adhesion genes.

Prediction of pathogenicity of rare copy number variations (CNVs), a genomic alteration known to contribute to the etiology of autism spectrum disorder (ASD), represents a serious limitation to interpreting genetic tests, particularly for genetic counseling purposes. Chromosomal microarray analysis (CMA) was conducted in a unique collection of 144 Brazilian individuals with ASD of strong European and African ancestries. Rare CNVs were detected in 39 patients: 41 of unknown significance (VUS), four pathogenic and one likely pathogenic CNVs (clinical yield of 4.1%; 5/122). Based on gene content and recurrence in three large cohorts [a Brazilian neurodevelopmental disorder cohort, the autism MSSNG cohort, and the Canadian-based Centre for Applied Genomics microarray database], this work strengthened the pathogenicity of 14 genes (FAT1, CAMK4, BIRC6, DPP6, CSMD1, CTNNA3, CDH8/CDH11, CDH13, OR1C1, CNTN6, CNTNAP4, FGF2 and PTPRN2) within 14 CNVs. Notably, enrichment of cell adhesion proteins to ASD etiology was identified (p < 0.05), highlighting the importance of these gene families in the etiology of ASD.

Is There a Link Between Nailfold Videocapillaroscopy and Pulmonary Function Tests in Systemic Sclerosis Patients?: A 24-Month Follow-up Monocentric Study.

BACKGROUND/OBJECTIVE: The aim of this study was to explore the associations between nailfold videocapillaroscopy (NVC) and pulmonary function tests (PFTs) in systemic sclerosis (SSc) patients. METHODS: This was a longitudinal study with follow-up of unselected Brazilian SSc patients. Baseline clinical examination, serological workup, high-resolution chest tomography, and NVC were performed. Pulmonary function test was performed at baseline and after 24 months. Pulmonary function test worsening over time was defined as either a ΔFVC decline ≥10% or a ΔFVC decline ≥5% and <9%, combined with a ΔDLCO decline ≥15%, at 24 months. The NVC parameters were quantitatively (capillary density number, dimension, morphology, and hemorrhages) and qualitatively (NVC pattern) evaluated according to the consented standardized definitions of the EULAR Study Group on Microcirculation in Rheumatic Diseases. RESULTS: Seventy-nine patients were included. Fifty-nine were rated to have a scleroderma pattern (6 "early"/16 "active"/37 "late"). The mean FVC and DLCO were 76.8% and 67.2% at baseline and 73.8% and 64.3% at 24 months, respectively. After multivariate analysis, we found that a reduced baseline FVC was associated with reduced capillary density (odds ratio [OR], 11; 95% confidence interval [CI], 1.5-90.7; p = 0.03) and a reduced baseline DLCO associated with the late scleroderma pattern (OR, 6.75; 95% CI, 1.09-42; p = 0.03). No association between worsening of PFT over time and NVC was found. CONCLUSIONS: The association between NVC and PFTs might corroborate the link between microangiopathy and interstitial lung disease in patients with SSc. This finding might strengthen the idea of incorporating NVC as a tool to predict progressive interstitial lung disease in these patients in the future.

Improved survival in patients with thyroid function test abnormalities secondary to immune-checkpoint inhibitors.

Immune-checkpoint inhibitors (ICI) are monoclonal antibodies which target molecules to enhance antitumor response. Several adverse events have been described and the major ICI-related endocrinopathies are thyroid dysfunction and hypophysitis. Its occurrence has been associated with improved outcomes, but it is still to be proven. We performed a retrospective study of patients treated with ICI between 2014 and 2019 at an oncologic center to characterize thyroid function test abnormalities (TFTA) and to evaluate clinical outcomes. We excluded patients without regular monitoring of thyroid function, with previous thyroid or pituitary disease, previous head/neck radiotherapy and who performed only one ICI cycle. We included 161 of 205 patients treated with pembrolizumab, nivolumab or ipilimumab for several neoplasms, with a median duration of 18.9 weeks (9.1-42.6) of ICI treatment and 49.4 weeks (26.5-75.8) of follow-up. New-onset TFTA was diagnosed in 18% of patients (n = 29), in median at 10.6 weeks (6.1-31.1) of ICI therapy. On the whole, 8.7% had primary hypothyroidism, 4.3% central hypothyroidism, 2.5% biphasic thyroiditis and 2.5% thyrotoxicosis. Patients who experienced primary or central thyroid dysfunction had a significantly improved overall response rate (58.6% vs 34.2%, p = 0.015) and overall survival (3.27 vs 1.76 years, p = 0.030), compared to the control group. The risk of mortality was two times higher for control group (adjusted HR = 2.43, 95% CI 1.13-5.23, p = 0.023). This study recognizes that primary and central thyroid dysfunction can be a predictive clinical biomarker of a better response to ICI across several neoplasms.

Pulmonary hypertension in systemic sclerosis: diagnosis by systematic screening and prognosis after three years follow-up.

BACKGROUND: Systemic sclerosis (SSc) is a rare disease, and the presence of pulmonary hypertension can be a determining factor in prognosis. The aim of this study was to evaluate the diagnosis, profile, and prognosis of systemic sclerosis pulmonary hypertension (SSc-PH) diagnosed by systematic screening in a Brazilian population. METHODS: A cohort of SSc patients underwent systematic screening for SSc-PH. Patients were referred for right heart catheterization (RHC) according to transthoracic echocardiogram or a combination of diagnostic tools. The clinical, immunological, and hemodynamic features and prognosis after 3 years were evaluated. RESULTS: Twenty patients underwent RHC. SSc pulmonary arterial hypertension (SSc-PAH) was the most common group of SSc-PH. These patients had long disease duration, high urate levels and highly elevated mean pulmonary arterial pressure (mPAP) and peripheral vascular resistance (PVR) on hemodynamics. Patients with mPAP > 20- < 25 mmHg had hemodynamic features of intermediate disease. Patients with SSc-PH associated to interstitial lung disease (SSc-ILD-PH) had signs of vasculopathy on hemodynamics. In patients with no-SSc-PH, the survival at 1, 2, and 3 years was 96%, 92% and 92%, respectively and in patients with SSc-PH it was 86.7%, 60% and 53.3%, respectively. CONCLUSIONS: Patients identified with SSc-PAH and SSc-ILD-PH in our screening had severe clinical and hemodynamic features. Mortality remains high in SSc-PH but was more related to Bo-PAH and SSc-ILD-PH, while in SSc-PAH, the prognosis was better. TRIAL REGISTRATION: Current Controlled Trials ISRCTN 72968188, July 8th, 2021. Retrospectively registered.

Developing a tool to monitor knowledge translation in the health system: results from an international Delphi study.

BACKGROUND: It is generally accepted that evidence-informed decision making contributes to better health system performance and health outcomes, yet we are lacking benchmarks to monitor the impact of national health information systems (HIS) in policy and practice. Hence in this study, we have aimed to identify criteria for monitoring Knowledge Translation (KT) capacity within countries. METHODS: We conducted a web-based Delphi with over 120 public health professionals from 45 countries to reach agreement on criteria to monitor KT at the level of national HIS. Public health professionals participated in three survey rounds, in which they ranked 85 preselected criteria and could suggest additional criteria. RESULTS: Experts working in national (public) health agencies and statistical offices, as well as in health policy and care agreed on 29 criteria which constitute the Health Information (HI)-Impact Index. The criteria cover four essential domains of evaluation: the production of high-quality evidence, broad access and dissemination, stakeholder engagement and knowledge integration across sectors and in civil society. The HI-Impact Index was pretested by officials working in ministries of health and public health agencies in eight countries; they found the tool acceptable and user-friendly. CONCLUSIONS: The HI-Impact Index provides benchmarks to monitor KT so that countries can assess whether high-quality evidence can be easily accessed and used by the relevant stakeholders in health policy and practice, by civil society and across sectors. Next steps include further refining the procedure for conducting the assessment in routine, and sharing experiences from HIS evaluations using the HI-Impact Index.

Comparison Between Lung Ultrasound and Computed Tomographic Findings in Patients With COVID-19 Pneumonia.

OBJECTIVES: The aim of this study was to describe findings from lung ultrasound (LUS) and computed tomography (CT) in health professionals with coronavirus disease 2019 pneumonia and to evaluate the associations of the findings of both tests. METHODS: This cross-sectional observational study evaluated 45 health professionals who were initially seen in screening tents and had a diagnosis of coronavirus disease 2019 as confirmed by a reverse transcription polymerase chain reaction and lung involvement diagnosed by LUS. Subsequently, these individuals were admitted to the hospital, where chest CT was performed. Aeration scores were obtained for the LUS examinations based on the following findings: more than 2 B-lines, coalescent B-lines, and subpleural consolidations. A subjective assessment of the extent of lung disease on CT was performed on the basis of the percentage of lung parenchyma involvement as follows: 25% or less, 25% to 50%, and greater than 50%. RESULTS: Regarding LUS signs, more than 2 B-lines, coalescent B-lines, and subpleural consolidations were present in 73.3%, 68.2%, and 24.4% of cases, respectively. The main findings on CT were ground glass opacities, a crazy-paving pattern, and consolidations (66.7%, 20%, and 20% of cases); 17.8% of cases had examinations without abnormalities. Patients with more than 2 B-lines on LUS had more ground glass opacity areas on CT (P = .0007), whereas patients with subpleural consolidations on LUS had more consolidations on CT (P < .0001). In addition, patients with higher LUS aeration scores had more extensive disease on CT (P < .0001). CONCLUSIONS: Lung ultrasound can detect lung injury even in the presence of normal CT results. There are associations between the abnormalities detected by both methods, and a relationship also exists between LUS aeration scores and the disease extent on CT.

Cytotoxicity of 4-substituted quinoline derivatives: Anticancer and antileishmanial potential.

Chemical modifications of quinoline moiety have been recognized as a useful strategy to development of new drugs. Here, the cytotoxicity of a set of twenty-four 4-substituted quinolines (named HTI) was screened for their antitumor and antileishmanial potential in vitro, and the underlying mechanisms investigated. HTI 21 and HTI 22 exhibited the highest cytotoxicity, being selected to the subsequent studies. Both derivatives induced caspase-dependent apoptosis associated to the dissipation of the mitochondrial transmembrane potential (ΔΨ) and ROS generation. HTI-induced cell death was calcium dependent, associated to thiol oxidation and cysteine proteases activation. In isolated mitochondria, HTI derivatives promoted mitochondrial permeabilization by different mechanisms. The inhibition of BCL-2 by venetoclax enhanced the HTI-induced cytotoxicity. Regarding the inhibition of cysteine proteases type B of Leishmania mexicana, HTI 15 exhibited the most potent inhibitory activity through a linear non-competitive mechanism. These data highlight the therapeutic potential of 4-substituted quinolines as antitumor and antileishmanial drugs.

Socioeconomic inequalities in suicide mortality in European urban areas before and during the economic recession.

BACKGROUND: Few studies have assessed the impact of the financial crisis on inequalities in suicide mortality in European urban areas. The objective of the study was to analyse the trend in area socioeconomic inequalities in suicide mortality in nine European urban areas before and after the beginning of the financial crisis. METHODS: This ecological study of trends was based on three periods, two before the economic crisis (2000-2003, 2004-2008) and one during the crisis (2009-2014). The units of analysis were the small areas of nine European cities or metropolitan areas, with a median population ranging from 271 (Turin) to 193 630 (Berlin). For each small area and sex, we analysed smoothed standardized mortality ratios of suicide mortality and their relationship with a socioeconomic deprivation index using a hierarchical Bayesian model. RESULTS: Among men, the relative risk (RR) comparing suicide mortality of the 95th percentile value of socioeconomic deprivation (severe deprivation) to its 5th percentile value (low deprivation) were higher than 1 in Stockholm and Lisbon in the three periods. In Barcelona, the RR was 2.06 (95% credible interval: 1.24-3.21) in the first period, decreasing in the other periods. No significant changes were observed across the periods. Among women, a positive significant association was identified only in Stockholm (RR around 2 in the three periods). There were no significant changes across the periods except in London with a RR of 0.49 (95% CI: 0.35-0.68) in the third period. CONCLUSIONS: Area socioeconomic inequalities in suicide mortality did not change significantly after the onset of the crisis in the areas studied.

Using the quality by design (QbD) approach to optimize formulations of lipid nanoparticles and nanoemulsions: A review.

Quality-by-design (QbD) approach has been applied to optimize lipid-based nanosystems formulations, including solid lipid nanoparticles (SLN), nanostructured lipid carriers (NLC) and nanoemulsions, besides being increasingly requested by regulatory authorities. Different mathematical models and statistical tests have been used, with similar conclusions regarding the parameters that influence the physical features of the resulting nanosystems. These include, variations in composition (e.g. lipid(s) and/or emulsifier(s)) and manufacturing parameters (e.g. emulsification rate and/or time, sonication amplitude and/or time, and homogenization pressure and/or cycles). These are critical parameters that influence nanoparticle/globule mean size, polydispersity index, zeta potential, drug encapsulation efficiency and in vitro drug release. This review addresses the concepts and applications of QbD for the development of lipid-based nanosystems, reporting successful examples published in the last 2 years. Although, some limitations have been identified, it is expected that in the upcoming years the application of QbD in pharmaceutical development will be an established approach.

Cutaneous melanoma associated with naevi prevalence: A 15-year cross-sectional retrospective study.

BACKGROUND/OBJECTIVES: Melanoma may develop de novo or naevus associated (NAM). The exact prevalence and features of NAM are not fully elucidated. METHODS: A 15-year cross-sectional retrospective study was performed of all melanoma cases diagnosed and treated at the skin cancer centre of the University of Naples Federico II from September 2003 to August 2018. Data collected included patient's age, gender, melanoma anatomic site, Breslow thickness, and histolopathology including melanoma-associated lesion characteristics. RESULTS: A total of 1986 melanomas were included in the study. Based on histolopathogical examination, NAM represented 8.4% (n = 167) with de novo melanoma representing the great majority of the melanomas (91.6%). NAM was significantly more common in younger age compared to de novo melamoma (mean age 48 ± 14.9 vs 54.3 ± 15.9 years, P < 0.001), and more frequently involved the trunk (62.3% vs 51.8% P = 0.01). Mean Breslow thickness was significantly higher in de novo melanoma  compared to NAM (0.97 ± 1.48 mm vs 0.83 ± 0.95, P < 0.001). However, in situ melanoma was more commonly observed in de novo melanoma (n = 640, 35.2%) rather than NAM (n = 41, 24.5%; P < 0.01) whereas invasive melanoma represented 75.5% (n = 126) of NAM and 64.8% (n = 1179) of de novo melanoma, P < 0.01. CONCLUSIONS: NAM represent a small percentage of melanomas (8.4%) compared to de novo melanoma. NAM appeared to be significantly more common in younger age and more frequently involved the trunk, being associated with an overall better prognosis, due to a lower mean Breslow thickness respect to de novo melanoma.

Dermoscopic patterns of intradermal naevi.

BACKGROUND: Intradermal naevi represent a benign histopathological variant of common melanocytic naevi. Studies describing dermoscopic criteria of dermal naevi are very limited. OBJECTIVES: To identify dermoscopic features of dermal naevi in order to facilitate differential diagnosis from malignant lesions. METHODS: A 15-year retrospective study was performed to evaluate the dermoscopic characteristics of 202 dermal naevi, histopathologically diagnosed through the analysis of digital dermoscopic images performed with polarised light dermoscopy. For each lesion, vascular pattern, pigment pattern and other dermoscopic clues were evaluated. RESULTS: 147 Unna naevi and 55 Miescher naevi were included in the study. Brown pigment (37.1%) was the pigment pattern most frequently observed in both Unna and Miescher naevi, followed by cobblestone pattern (30.6%) in Unna naevi and white areas (23.6%) and dotted/globule pattern (20%) in Miescher naevi. As regards the vascular patterns, the polymorphic one was the most frequently observed (34.6%). The combination between comma-shaped and arborising vessels was the most common among all naevi. CONCLUSIONS: Our study describes the dermoscopic features of dermal naevi that may help to differentiate them from malignant lesions such as basal cell carcinoma, amelanotic melanoma and Spitz naevi.

Advancing tools to promote health equity across European Union regions: the EURO-HEALTHY project.

BACKGROUND: Population health measurements are recognised as appropriate tools to support public health monitoring. Yet, there is still a lack of tools that offer a basis for policy appraisal and for foreseeing impacts on health equity. In the context of persistent regional inequalities, it is critical to ascertain which regions are performing best, which factors might shape future health outcomes and where there is room for improvement. METHODS: Under the EURO-HEALTHY project, tools combining the technical elements of multi-criteria value models and the social elements of participatory processes were developed to measure health in multiple dimensions and to inform policies. The flagship tool is the Population Health Index (PHI), a multidimensional measure that evaluates health from the lens of equity in health determinants and health outcomes, further divided into sub-indices. Foresight tools for policy analysis were also developed, namely: (1) scenarios of future patterns of population health in Europe in 2030, combining group elicitation with the Extreme-World method and (2) a multi-criteria evaluation framework informing policy appraisal (case study of Lisbon). Finally, a WebGIS was built to map and communicate the results to wider audiences. RESULTS: The Population Health Index was applied to all European Union (EU) regions, indicating which regions are lagging behind and where investments are most needed to close the health gap. Three scenarios for 2030 were produced - (1) the 'Failing Europe' scenario (worst case/increasing inequalities), (2) the 'Sustainable Prosperity' scenario (best case/decreasing inequalities) and (3) the 'Being Stuck' scenario (the EU and Member States maintain the status quo). Finally, the policy appraisal exercise conducted in Lisbon illustrates which policies have higher potential to improve health and how their feasibility can change according to different scenarios. CONCLUSIONS: The article makes a theoretical and practical contribution to the field of population health. Theoretically, it contributes to the conceptualisation of health in a broader sense by advancing a model able to integrate multiple aspects of health, including health outcomes and multisectoral determinants. Empirically, the model and tools are closely tied to what is measurable when using the EU context but offering opportunities to be upscaled to other settings.

Changes in lung ultrasound of symptomatic healthcare professionals with COVID-19 pneumonia and their association with clinical findings.

PURPOSE: To evaluate ultrasound signs of coronavirus disease-19 (COVID-19) pneumonia in symptomatic healthcare professionals and to correlate those changes with clinical findings. METHODS: All patients underwent real-time polymerase chain reaction (RT-PCR), lung ultrasound (LUS) and clinical evaluation on the same day. In each of the 12 areas evaluated in the LUS, the LUS signs were scored to generate the aeration score. RESULTS: A total of 409 participants had positive PCR, with a median age of 41 (35-51) years. All participants had clinical symptoms, with cough in 84.1%, fever in 69.7%, and dyspnea in 36.2% of cases. In the LUS, 72.6% of participants had B-lines >2, 36.2% had coalescent B-lines, and 8.06% had subpleural consolidations. The median aeration score was 3 (2-7). The aeration score differed significantly regarding the presence of cough (P = .002), fever (P = .001), and dyspnea (P < .0001). The finding of subpleural consolidations in the LUS showed significant differences between participants with or without dyspnea (P < .0001). CONCLUSIONS: In healthcare professionals with COVID-19, LUS plays a key role in the characterization of lung involvement. Although B-lines are the most common ultrasound sign, subpleural consolidations are those that most impact the respiratory condition.
