Burden of visible [face and hands] skin diseases: Results from a large international survey.

BACKGROUND: While numerous surveys over the last decade have evaluated the burden of skin diseases, none have focused on the specific impact of disease-location on the hands and face. AIM: The purpose of our study was to evaluate the burden of 8 skin diseases on the multidimensional aspects of subjects' daily lives in respect to their location on visible body areas (face or hands) versus non-visible areas. METHODS: This was a population-based study in a representative sample of the Canadian, Chinese, Italian, Spanish, German and French populations, aged over 18 years using the proportional quota sampling method. All participants were asked (i) to complete a specific questionnaire including socio-demographic characteristics, (ii) to declare if they had a skin disease. All respondents with a skin disease were asked (iii) to specify the respective disease locations (hands, face, body) and (iv) to complete the DLQI questionnaire. Respondents with 8 selected skin diseases were asked (v) to complete a questionnaire evaluating the impact of the skin disease on their daily life, including their professional activity, social relations, emotional and intimate life, leisure, sports activities and perceived stigma. RESULTS: A total of 13,138 adult participants responded to the questionnaire, of whom 26.2 % (n = 3,450) had skin diseases, and 23.4 % (n = 3,072) reported having one of the 8 selected skin diseases. Fifty-three percent were women and the mean age was 39.6 ±â€¯15.5 years. The QoL was mostly impaired when the visible localization was solely on the hands as compared with the face (38 % had a DLQI > 10 versus 22 % respectively). More subjects with a visible localization on the hands reported felt-stigma, having difficulty falling asleep and felt that their sex life had been affected. CONCLUSION: Special attention should be given to patients with skin disease on the hands and face as they are at higher risk of social exclusion and lower quality of life.

Impact of the COVID-19 pandemic on children with psoriasis.

BACKGROUND: Children with psoriasis may have been directly impacted by the COVID-19 pandemic and their illness may also have affected their ability to follow preventive measures. OBJECTIVE: To investigate the impact of the COVID-19 pandemic on children with psoriasis. METHODS: A survey of children (<18 years) with psoriasis, conducted from June 10 to June 29, 2020. RESULTS: In total, 92 children were included: 71.7% had psoriasis lesions at the time of home lockdown while 45.2% were receiving systemic treatments, and two contracted COVID-19. During lockdown, psoriasis worsened in 47.3% of the children and 18.8% stopped their systemic treatments, mainly for reasons linked to the pandemic. A total of 41.3% had a consultation for psoriasis during lockdown (71.1% by teleconsultation): 39.5% due to worsening of their psoriasis and 21.1% for pandemic-related issues. Among patients not having a consultation during lockdown, 27.5% had a cancellation by the doctor and 9.3% had concerns over going to see the doctor. Finally, 22.8% of patients reported finding it difficult to respect hygiene measures because of their psoriasis, e.g., application of alcohol-based hand sanitizers (47.6%), handwashing routines (42.9%), and wearing a mask (28.6%). CONCLUSIONS: This study demonstrates the major clinical impact of the COVID-19 pandemic on children with psoriasis. Teleconsultations played a key role in patient management as regards patient monitoring, provision of information, and renewal of treatments. It is vital that we learn from these data to improve and adapt the monitoring of chronic dermatoses in both children and adults in the event of a future health crisis.

Out-of-pocket expenditures in France to manage psoriasis in adult patients: results from an observational, cross-sectional, non-comparative, multicentre study.

BACKGROUND: In 2018 in France, overall mean health-related out-of-pocket (OOP) expenditures were 214.00€/year/patient. AIM: To evaluate OOP expenditures for psoriasis patients in France. METHODOLOGY: Observational, cross-sectional, non-comparative, multicentre study in 3000 patients with clinically confirmed psoriasis who responded to a specific digital questionnaire collecting demographic and socio-economic characteristics, assessing the 3 domains (severity, psychosocial impact and past history and interventions) of the patient's Simplified Psoriasis Index (sa-SPI) and expenditures to manage psoriasis, including OOP. Multivariate linear regression was conducted to search for factors associated with higher OOP. RESULTS: In total, 2681 patients completed the questionnaire and, of those, 2562 provided clinically validated data. Overall, 60% were women; the mean age was 49.4 ± 14.8 years. 30% of the patients declared that they suffered from psoriatic arthritis. The final mean sa-SPI core was 10.86 ± 9.70. Of these 2562 patients, 243 (9.5%) had severe, 442 (17.3%) moderate and 1877 (73.3%) mild psoriasis. In addition, 932 (36.4%) patients reported facial involvement, 724 (28.25%) genital impairment and 1124 (43.8%) lesions on the limbs. Mean OOP expenditures to manage psoriasis per patient were 531.00€, 439.74€ ± 939.85€ for patients with mild, 791.06€ ± 1367.67€ with moderate and 1077.64€ ± 1680.14€ for patients with severe psoriasis. For patients with psoriasis in the genital area, the median amount of expenditures (251.17€; CI95% [138.35;363.99]) was significantly higher than that for the face (183.85€; CI95% [78.76;288.94]) or limbs (199.96€; CI95% [93.77;306.15); (P < 0.001). More than 90% of the patients had OOP expenditures for over-the-counter products (97.5%) and alternative care (92.0%), especially for emollients and/or hydrating products. CONCLUSION: In France, in 2019, OOP expenditures to manage psoriasis were on average more than twice as high as the overall mean health-related OOP expenditures estimated by the French Health Agency in 2018. These results should lead health authorities to review certain standards of healthcare reimbursement.

Tile Drainage as a Hydrologic Pathway for Phosphorus Export from an Agricultural Subwatershed.

Cyanobacteria growth in Missisquoi Bay of Lake Champlain is triggered by the P load carried by tributaries in surrounding watersheds where agriculture is a dominant land use. The objective of this study was to apportion the total P (TP) load in streamflow from an agricultural subwatershed into distinct hydrologic pathways: groundwater resurgence, surface runoff, and tile drainage components (matrix flow and preferential flow). Stream discharge during peak flow was separated into these four components using electrical conductivity (EC)-discharge relationships developed from the stream water EC at the subwatershed outlet and from EC values of surface runoff and tile drain water in 10 fields within the subwatershed. The four-component hydrograph model revealed that 46 to 67% of the TP load at the outlet originated from surface runoff during peak flow. Preferential flow was responsible for most of the particulate P and dissolved reactive P loads lost through tile drainage. Groundwater resurgence was a minor source of TP, whereas other sources such as streambank erosion and resuspended sediments contributed up to 21% of the TP load and from 36 to 41% of the particulate P load at the subwatershed outlet. This work confirms that tile drainage contributes to the TP load in agricultural subwatersheds in the Missisquoi Bay region.

The impact of psoriasis on professional life: PsoPRO, a French national survey.

BACKGROUND: The physical, social and mental burden of psoriasis is well known, but its occupational impact has been less investigated. OBJECTIVE: To assess the impact of psoriasis on the working life of patients compared with the general population. METHODS: A national survey compared people with and without psoriasis using online questionnaires. In addition to the demographic, medical and professional characteristics, data on recent absenteeism and presenteeism were captured using the validated WPAI-PSO questionnaire. RESULTS: The patient sample comprised 714 with psoriasis (PsO), including 81 treated with systemic therapies (PsoST), and 84 with associated psoriatic arthritis (PsO + PsA). The control sample comprised 604 active subjects representative of the French population. Compared to controls, the impact of the disease on working life was no greater in PsO patients. Conversely, unemployment within the past 5 years and mean number of sick leaves within the previous year were more frequent in PsO + PsA. In patients with active psoriasis skin lesions, all aspects of the WPAI questionnaire were negatively impacted in PsoST and PsO + PsA patients, but not in PsO patients: Levels of absenteeism were 3.3% in controls, 5.6% in PsO (NS), 8.3% in PsoST (P < 0.05) and 13.0% in Ps0 + PsA (P < 0.05); impairment in presenteeism reached 27.0%, 21.2% (NS), 43.5% (P < 0.05) and 53.2% (P < 0.05), respectively, while overall work impairment was 27.9%, 22.2% (NS), 46.3% (P < 0.05) and 57.6% (P < 0.05), respectively. Nevertheless, a higher proportion of PsoST and PsO + PsA patients reported that work was more important than any other activity in their life. CONCLUSION: The occupational impact of psoriasis is important and significant in patients who receive systemic therapy or have concurrent PsA but minimal or absent in other psoriasis patients. The findings show that psoriasis patients have a high level of motivation to work.

Highly controllable direct femtosecond laser writing of gold nanostructures on titanium dioxide surfaces.

A highly reproducible and controllable deposition procedure for gold nanostructures on a titanium dioxide (TiO2) surface using femtosecond laser light has been demonstrated. This is realized by precisely focusing onto the TiO2 surface in the presence of a pure gold ion solution. The deposition is demonstrated both in dot arrays and line structures. Thanks to the multi-photon excitation, we observe that the deposition area of the nanostructures can be confined to a degree far greater than the diffraction limited focal spot. Finally, we demonstrate that catalytic activity with visible light irradiation is enhanced, proving the applicability of our new deposition technique to the catalytic field.

A novel method for in situ synthesis of SERS-active gold nanostars on polydimethylsiloxane film.

A novel one-step in situ synthesis of gold nanostars (AuNSs) on a pre-cured polydimethylsiloxane (PDMS) film is proposed for the fabrication of highly sensitive surface-enhanced Raman scattering (SERS) substrates. Plasmonic activity of the substrates was investigated by collecting SERS maps of 4-mercaptobenzoic acid (4-MBA). The applicability of these flexible substrates is further demonstrated by SERS-based pesticide detection on fruit skin.

T-cadherin gene variants are associated with type 2 diabetes and the Fatty Liver Index in the French population.

AIM: Adiponectin is an adipocyte-secreted protein associated with insulin sensitivity. T-cadherin is a receptor for high and medium molecular weight adiponectin. In GWAS, T-cadherin gene (CDH13) polymorphisms are associated with circulating adiponectin levels. This study investigated the associations between genetic variants of CDH13 and type 2 diabetes (T2D), and its related parameters, in a Caucasian population. METHODS: Two polymorphisms of CDH13 (rs11646213 and rs3865188) were genotyped in two French cohorts, a general population from the D.E.S.I.R. study (n=5212) and people with T2D in the DIABHYCAR study (n=3123). Baseline adiponectin levels were measured in D.E.S.I.R. participants who were normoglycaemic at baseline, but hyperglycaemic after 3 years (n=230), and in controls who remained normoglycaemic (n=226) throughout. RESULTS: In a cross-sectional analysis, CDH13 genotype distributions differed between those with and without T2D, with T2D odds ratios (OR) of 1.11 (95% CI: 1.04-1.18; P=0.001) and 0.92 (95% CI: 0.87-0.98; P=0.01) for rs11646213 and rs3865188, respectively. The rs11646213 variant, associated with a higher OR for T2D, was also associated with higher BMI (P=0.03) and HbA1c (P=0.006), and lower plasma adiponectin levels (P=0.03) in the D.E.S.I.R. PARTICIPANTS: Conversely, the rs3865188 variant, associated with a lower OR for T2D, was also associated with lower BMI (P=0.03), HbA1c (P=0.02) and Fatty Liver Index (FLI; P≤0.01), and higher plasma adiponectin levels (P=0.002). Associations with HbA1c, FLI and adiponectin levels persisted after adjusting for BMI. CONCLUSION: CDH13 polymorphisms are associated with prevalent T2D in this French population study. The association may be mediated through effects on BMI and/or plasma adiponectin.

Adoption of pharmacogenomic testing by US physicians: results of a nationwide survey.

To develop a benchmark measure of US physicians' level of knowledge and extent of use of pharmacogenomic testing, we conducted an anonymous, cross-sectional, fax-based, national survey. Of 397,832 physicians receiving the survey questionnaire, 10,303 (3%) completed and returned it; the respondents were representative of the overall US physician population. The factors associated with the decision to test were evaluated using χ(2) and multivariate logistic regression. Overall, 97.6% of responding physicians agreed that genetic variations may influence drug response, but only 10.3% felt adequately informed about pharmacogenomic testing. Only 12.9% of physicians had ordered a test in the previous 6 months, and 26.4% anticipated ordering a test in the next 6 months. Early and future adopters of testing were more likely to have received training in pharmacogenomics, but only 29.0% of physicians overall had received any education in the field. Our findings highlight the need for more effective physician education on the clinical value, availability, and interpretation of pharmacogenomic tests.

Intensifying glycaemic control with insulin reduces adiponectin and its HMW isoform moderately in type 2, but not in type 1, diabetes.

INTRODUCTION: As the impact of diabetes control was not tested on adiponectin (ADPN) levels, this study was designed to assess whether or not controlling hyperglycaemia can affect ADPN. PATIENTS AND METHODS: A total of 15 T1D and 48 T2D patients with HbA(1c) greater than 10% were studied at the time of hospitalization for uncontrolled diabetes. Total, and high-, medium- and low-molecular-weight (HMW, MMW, LMW) ADPN were measured at the time of study inclusion, on days 1 and 8, and at 1, 3 and 6 months after insulin treatment. RESULTS: While diabetes control improved, total and HMW APDN decreased on days 1 and 8, but remained steady thereafter in T2D patients. In T1D patients, ADPN levels remained unchanged throughout the study. CONCLUSION: Glycaemic control with insulin reduces ADPN in T2D patients in the short-term, but was ineffective in T1D.

Rosiglitazone and pioglitazone increase fracture risk in women and men with type 2 diabetes.

AIM: The objectives of the study were to determine whether thiazolidinedione (TZD) use is associated with an increased risk of fracture in men and women with type 2 diabetes mellitus and to compare the effects of pioglitazone and rosiglitazone. MATERIALS AND METHODS: A research database of integrated pharmacy and medical claims was analysed using Cox models adjusted for age, gender, chronic obstructive pulmonary disease, asthma, osteoporosis, stroke, prior fracture and chronic disease score. Patients were followed for 540 days. RESULTS: There was a 39% higher [adjusted hazard ratio (HR), 1.39; 95% confidence interval (CI), 1.32-1.46] incidence of fractures in men and women exposed to a TZD (n = 69047; age = 56 +/- 5 years; 59% men; 48% rosiglitazone) compared with that in control patients (n = 75352; age = 56 +/- 5 years; 51% men). Men treated with a TZD had a higher likelihood of fracture than control patients (adjusted HR rosiglitazone, 1.47; 95% CI, 1.38-1.56; adjusted HR pioglitazone, 1.43; 95% CI, 1.34-1.52). The HRs associated with pioglitazone (adjusted HR, 1.43; 95% CI, 1.34-1.52) and rosiglitazone (adjusted HR, 1.47; 95% CI, 1.38-1.56) were almost identical. TZD use was associated with a higher fracture risk in women aged above and below 50 years and in men aged above 50 years. CONCLUSIONS: Our findings add support to the growing literature that TZD treatment is associated with an increased risk of fractures in both men and women, that effects of rosiglitazone and pioglitazone are similar and that fracture risk is increased even in younger women.

Sex hormone-binding globulin predicts the incidence of hyperglycemia in women: interactions with adiponectin levels.

OBJECTIVE: Previous evidence has suggested that a low sex hormone-binding globulin (SHBG) concentration is associated with insulin-resistance and a low adiponectin concentration. We investigated the association between SHBG and the risk of hyperglycemia in each sex and we determined potential interactions between SHBG and adiponectin levels in the development of dysglycemia. DESIGN: We used a nested case-control design in the large prospective study, Data from an Epidemiological Study on the Insulin Resistance Syndrome (DESIR). We studied 227 men and women who were normoglycemic at baseline but hyperglycemic at 3 years (glycemia > or = 6.1 mmol/l or type 2 diabetes). They were matched for sex, age, and body mass index with 227 subjects who remained normoglycemic at 3 years. RESULTS: At baseline, the concentration of SHBG was significantly lower in women who subsequently developed hyperglycemia than in those who remained normoglycemic, with no difference for men. In multiple regression, SHBG at baseline was as an independent determinant of plasma adiponectin levels, in both women (P<0.0001) and men (P=0.002). In multivariate conditional logistic regression taking into account physical activity and changes in waist circumference over the follow-up, plasma SHBG remained significantly associated with the development of hyperglycemia in women but not in men. These associations persisted after adjustment for fasting insulinemia, high fasting glucose, and adiponectin levels. CONCLUSIONS: These findings suggest that a low SHBG level is a strong risk marker for dysglycemia in women, independently of both adiponectinemia and insulinemia. SHBG may therefore improve the identification of women at risk of diabetes.

Increased plasma adiponectin concentrations are associated with microangiopathy in type 1 diabetic subjects.

AIMS/HYPOTHESIS: Insulin resistance is related to an increased risk of diabetic retinopathy and nephropathy in type 1 diabetes. Patients with insulin resistance and/or macrovascular disease have abnormally low levels of adiponectin. The aim of this study was to investigate the relationships between adiponectin and renal and retinal diabetic complications in type 1 diabetic patients. METHODS: In this 6-year prospective follow-up observational study, we evaluated the severity of retinopathy at baseline and determined the incident risk of microalbuminuria in 126 normoalbuminuric patients with type 1 diabetes. Each patient was age- and sex-matched to two non-diabetic control subjects. RESULTS: Plasma adiponectin concentrations were significantly higher in diabetic subjects than in control subjects (p < 0.0001). The adiponectin concentration was significantly higher in patients with severe diabetic retinopathy than in those without (39.1+/-14.0 vs 29.0+/-13.0 microg/ml, p = 0.0005). The 18 patients who developed persistent microalbuminuria had higher adiponectin concentrations than the other patients (35.8+/-14.5 vs 30.6+/-13.7 microg/ml). Increased adiponectin concentrations were independently associated with the occurrence of microalbuminuria (p = 0.0158) after adjustment for baseline urinary albumin concentration (p = 0.004), sex (p = 0.0054), blood pressure (NS) and metabolic control (NS). CONCLUSIONS/INTERPRETATION: The elevated adiponectin concentrations observed in subjects with microvascular disease may indicate an altered regulation of this adipocytokine in patients with complications associated with type 1 diabetes.

LEPR gene polymorphisms: associations with overweight, fat mass and response to diet in women.

BACKGROUND: In humans, a mutation of the leptin receptor gene (LEPR) leads to a rare obese syndrome of mendelian inheritance. However, obesity in humans results from interactions between genes and environment, mainly nutritional factors. Variations at the LEPR locus could be involved in the regulation of body weight. DESIGN: Genetic variations at the LEPR locus were screened in a selection of 30 French overweight subjects by Single Strand Conformation Polymorphism (SSCP) analysis, then an association study between genotypes and obesity phenotypes was performed in 179 French overweight patients recruited from the Nutrition Department of Bichat Hospital in Paris who were prescribed a low calorie diet and in 387 unrelated volunteers (98 overweight, 289 normal weight) drawn from the Stanislas Family Study in Nancy. RESULTS: Two new genetic variants were found: T + 70-->C (exon 1) and Asp (A) 96 Asp (G) (exon 4). In Nancy, the T + 70-->C polymorphism was associated with fat mass adjusted for BMI in women (P = 0.025). The genotype and allele frequencies of the Ser (T) 343 Ser (C) polymorphism (exon 9) were significantly different between normal and overweight women, with the T allele being more frequent in the overweight group (T frequency in Nancy, 0.82; in Nancy + Paris, 0.79) than in the normal weight group (0.69; P = 0.017 vs. Nancy overweight, P = 0.003 vs. Nancy + Paris overweight). In women from Nancy, fat mass adjusted for BMI was significantly associated with this polymorphism (P = 0.01). The overweight women carrying the C allele of this polymorphism lost more weight in response to low calorie diet than the non carriers (P = 0.006). CONCLUSIONS: In women, genetic variations at the LEPR gene level are associated with overweight and fat mass in a cross sectional study and with response to low calorie diet in an intervention study. These results indicate that variations at the leptin receptor locus are associated with common obesity phenotypes and are a part of the polygenic influences on the response to nutritional environment.
