RESUMEN

Differential cross sections for Compton scattering from the proton have been measured at scattering angles of 55°, 90°, and 125° in the laboratory frame using quasimonoenergetic linearly (circularly) polarized photon beams with a weighted mean energy value of 83.4 MeV (81.3 MeV). These measurements were performed at the High Intensity Gamma-Ray Source facility at the Triangle Universities Nuclear Laboratory. The results are compared to previous measurements and are interpreted in the chiral effective field theory framework to extract the electromagnetic dipole polarizabilities of the proton, which gives α_{E1}^{p}=13.8±1.2_{stat}±0.1_{BSR}±0.3_{theo},ß_{M1}^{p}=0.2∓1.2_{stat}±0.1_{BSR}∓0.3_{theo} in units of 10^{-4} fm^{3}.

RESUMEN

Alopecia areata is the third most common cause of dermatology consultations in children but the treatment of paediatric alopecia areata remains challenging. A systematic review of the literature about the treatment of alopecia areata in children (≤18 years old) was performed on 11 May 2020 by searching the PubMed, Scopus and EBSCO databases. The terms used for the search were: 'alopecia areata', 'alopecia totalis' or 'alopecia universalis' combined with 'paediatric', 'children' or 'childhood'. A total of 89 articles were included in final evaluation. The most commonly assessed treatment options in paediatric alopecia areata were topical immunotherapy (response rate in monotherapy: 54%; 187/345) intralesional glucocorticosteroids (75%; 211/280), systemic glucocorticosteroids (73%; 102/140), and anthralin (42%; 31/74). Topical glucocorticosteroids (81%; 35/43), systemic Janus kinase (JAK) inhibitors (90%; 27/30), topical calcineurin inhibitors (42%; 8/19), topical JAK inhibitors (65%; 11/17), PUVA therapy (56%; 9/16) and 308-nm excimer laser (77%; 10/13) were also evaluated. Additionally, evaluation in smaller numbers of paediatric patients included methotrexate (100%; 10/10), topical minoxidil (44%; 4/9) and cyclosporine (83%; 5/6). There were limited data considering children with alopecia areata treated with azathioprine, hydroxychloroquine, topical sildenafil, topical prostaglandin analogues, fractional carbon dioxide laser, leflunomide, mesalazine, apremilast, dupilumab, ustekinumab, efalizumab, botulinum toxin, and compound glycyrrhizin. On the basis of the limited data available glucocorticosteroids (systemic, intralesional or topical) and JAK inhibitors (systemic or topical) may be considered the best documented and most effective treatment options in alopecia areata in children. There are no sufficient paediatric data to compare treatment safety and relapse rates in these therapeutic modalities.

RESUMEN

The magnitude of the orbital magnetic moment and its role as a trigger of the Verwey transition in the prototypical Mott insulator, magnetite, remain contentious. Using 1s2p resonant inelastic x-ray scattering angle distribution (RIXS-AD), we prove the existence of noncollinear orbital magnetic ordering and infer the presence of dynamical distortion creating a polaronic precursor for the metal to insulator transition. These conclusions are based on a subtle angular shift of the RIXS-AD spectral intensity as a function of the magnetic field orientation. Theoretical simulations show that these results are only consistent with noncollinear magnetic orbital ordering. To further support these claims we perform Fe K-edge x-ray magnetic circular dichroism in order to quantify the Fe average orbital magnetic moment.

RESUMEN

BACKGROUND: Gut dysbiosis and increased intestinal permeability play a significant role in the pathogenesis of psoriasis and its comorbidities. Claudin-3 is a key component of tight junctions, which may serve as marker of gut barrier integrity. OBJECTIVES: The aim of the study was to investigate circulating plasma claudin-3 in patients with psoriasis and to evaluate clinical and metabolic factors, which determine its concentration. METHODS: This cross-sectional study included 60 patients with psoriasis (39 men and 21 women, mean age: 45.6 ± 12.1 years) and 30 healthy controls (18 men and 12 women, mean age: 46.3 ± 15.5 years) age, sex and body mass index-matched. Plasma claudin-3 concentration was measured using an enzyme-linked immunosorbent assay. RESULTS: Plasma claudin-3 concentration was significantly higher in patients with psoriasis in comparison with healthy control [median (interquartile range), 50.7 ng/mL (47.3-54.2) vs. 43.3 ng/mL (42.3-44.2), P < 0.001]. Patients who achieved ΔPASI90 response after 16 weeks of treatment showed tendency to decrease in circulating claudin-3 plasma concentration. Positive correlations between claudin-3 concentration and the PASI score (r = 0.828; P < 0.001) as well as claudin-3 and neutrophil-to-lymphocyte ratio (r = 0.847; P < 0.001) were found. A multivariable linear regression analysis confirmed association of claudin-3 with the PASI score (P < 0.001), neutrophil-to-lymphocyte ratio (P < 0.01) and active smoking (P < 0.05). CONCLUSION: Claudin-3, a biomarker for gut permeability, is increased in psoriasis and correlates with disease severity and smoking. Further investigations are needed to determine whether reinforcing intestinal barrier may be a new therapeutic target in psoriasis.

RESUMEN

INTRODUCTION: Alopecia areata and frontal fibrosing alopecia are common causes of eyebrow loss (madarosis). OBJECTIVE: Assessment of trichoscopic markers of eyebrow loss in alopecia areata and frontal fibrosing alopecia. MATERIALS AND METHODS: The analysis included 50 patients with scalp alopecia areata with madarosis, 50 patients with scalp frontal fibrosing alopecia with madarosis and 50 healthy controls. In every case, trichoscopy of the eyebrow area was performed. RESULTS: Empty follicular and eccrine duct openings were observed in all patients and presented predominantly as yellow dots. Exclamation mark hairs were only detected in patients with alopecia areata (30%). Tapered hairs, broken hair, black dots and Pohl-Pinkus constrictions were observed in 14%, 36%, 26% and 4% of patients with alopecia areata, respectively, 4%, 16%, 2% and 0% of patients with frontal fibrosing alopecia, respectively, and they were not present in healthy controls. Dystrophic hairs and whitish areas were observed only in patients with frontal fibrosing alopecia (28% and 32%, respectively). Eyebrow regrowth in distinct directions was present in 32% of patients with frontal fibrosing alopecia, 8% of patients with alopecia areata and 4% of healthy controls. Diffuse erythema was detected in 60% of patients with alopecia areata and frontal fibrosing alopecia and 56% of healthy controls. Vellus hairs and upright regrowing hairs were observed in patients with alopecia areata (62% and 58%, respectively), frontal fibrosing alopecia (60% and 84%, respectively) and healthy controls (100% and 100%, respectively). CONCLUSION: Trichoscopy of the eyebrow area is useful in diagnosing patients with isolated eyebrow loss. The most characteristic trichoscopic features of eyebrow loss in alopecia areata include exclamation mark hairs, tapered hairs, broken hairs and black dots. Frontal fibrosing alopecia of the eyebrows is characterized by the presence of dystrophic hairs, white areas and eyebrow regrowth in distinct directions.

RESUMEN

Sarcoidosis may affect lung function, working ability, overall mobility, and daily activity. In the present study we performed an analysis of clinical settings in patients with sarcoidosis to disentangle its influence on daily physical activity (PA). PA assessment (number of steps per day, daily energy expenditure) was performed by accelerometry during consecutive 7 days after discharge from hospital. Thirty patients with sarcoidosis, aged 46.4 ± 10.5, were enrolled in the study. Clinical data (age, gender, steroid consumption, weight, and comorbidities), lung function tests (forced expiratory volume in one second - FEV1, forced vital capacity - FVC, and lung diffusion for carbon monoxide - DLCO), mobility (6-minute walk test - 6 MWT) and physical performance (oxygen consumption at anaerobic threshold - VO2/AT) were estimated. The mean daily PA (5214 ± 2699 steps/day) and VO2max (22.3 ± 7.0 ml/kg/min) were lower when referenced to the age-group predicted values. A significant greater daily PA was observed in sarcoidosis patients without comorbidities compared with those having more than two comorbidities (p = 0.046). No association was found between steroid use, lung function, and 6MWT. Daily PA was associated with patients aerobic efficacy and VO2max (r = 0.38, p < 0.04). The findings demonstrate a significant influence of comorbidities on sarcoidosis patients' exercise tolerance and daily PA. Special treatment considerations, including the potential impact of comorbidities, may help optimize exercise regimes, link physical activity with health, and prevent sarcoidosis complications.

RESUMEN

Scientific reports underscore the importance of measuring the health-related quality of life in sarcoidosis patients. The present study seeks to define how sarcoidosis patients' quality of life, daily physical activity, and physical performance are related to each other. Seventeen patients (mean age 46.8 ± 8.8 years) suffering from sarcoidosis completed the following questionnaires: the fatigue assessment scale (FAS), the quality of life scale (SF-36 questionnaire), and the Borg dyspnea scale. Physical activity (PA) was assessed using accelerometry. Respiratory function, consisting of forced expiratory volume in one second (FEV1), forced vital capacity (FVC), forced expiratory volume in one second as a percentage of vital capacity (FEV1/%FVC), and diffusing capacity of the lungs for carbon monoxide (DLCO), were assessed. In addition, performance in 6-min walk test (MWT), aerobic capacity assessed from maximal oxygen uptake (VO2max), and the metabolic equivalent of task (MET) were evaluated. We found that daily PA (4566 ± 2378 steps/day) and VO2max (21.8 ± 5.9 ml/kg/min) were lower in sarcoidosis patients than the known predicted values in healthy age-matched individuals. There were significant inverse associations between the FAS score and 6MWT (r = -0.62; p < 0.01), and between SF-36 score and 6MWT (r = -0.55; p < 0.03). In contrast, SF-36 scores associated with fatigue and dyspnea scores (r = 0.72; p < 0.001 and r = 0.85; p < 0.001). These findings imply that sarcoidosis patients are less active compared with healthy subjects. The FAS and SF-36 scales seem to be effective tools for assessing the severity of fatigue in sarcoidosis patients.

RESUMEN

PURPOSE: A number of studies have tested the hypothesis that breast cancer patients with low-activity CYP2D6 genotypes achieve inferior benefit from tamoxifen treatment, putatively due to lack of metabolic activation to endoxifen. Studies have provided conflicting data, and meta-analyses suggest a small but significant increase in cancer recurrence, necessitating additional studies to allow for accurate effect assessment. We conducted a retrospective pharmacogenomic analysis of a prospectively collected community-based cohort of patients with estrogen receptor-positive breast cancer to test for associations between low-activity CYP2D6 genotype and disease outcome in 500 patients treated with adjuvant tamoxifen monotherapy and 500 who did not receive any systemic adjuvant therapy. METHODS: Tumor-derived DNA was genotyped for common, functionally consequential CYP2D6 polymorphisms (*2, *3, *4, *6, *10, *41, and copy number variants) and assigned a CYP2D6 activity score (AS) ranging from none (0) to full (2). Patients with poor metabolizer (AS = 0) phenotype were compared to patients with AS > 0 and in secondary analyses AS was analyzed quantitatively. Clinical outcome of interest was recurrence free survival (RFS) and analyses using long-rank test were adjusted for relevant clinical covariates (nodal status, tumor size, etc.). RESULTS: CYP2D6 AS was not associated with RFS in tamoxifen treated patients in univariate analyses (p > 0.2). In adjusted analyses, increasing AS was associated with inferior RFS (Hazard ratio 1.43, 95% confidence interval 1.00-2.04, p = 0.05). In patients that did not receive tamoxifen treatment, increasing CYP2D6 AS, and AS > 0, were associated with superior RFS (each p = 0.0015). CONCLUSIONS: This population-based study does not support the hypothesis that patients with diminished CYP2D6 activity achieve inferior tamoxifen benefit. These contradictory findings suggest that the association between CYP2D6 genotype and tamoxifen treatment efficacy is null or near null, and unlikely to be useful in clinical practice.

RESUMEN

The aim of this study was to examine the association of single-nucleotide polymorphisms (SNPs) in the gene encoding ficolin-2 protein (FCN2 gene) at positions -986 (rs17514136), -602 (rs3124953), and -4 (rs3124952) with dental caries in Polish children. Two hundred and sixty Polish Caucasian children aged 15 years were enrolled in this study: 82 with "higher" caries experience (DMFT >5) and 178 with "lower" caries experience (DMFT ≤5). In addition, subjects with caries experience (DMFT ≥1) and caries-free subjects (DMFT = 0) were compared. FCN2 SNPs were genotyped with PCR-RFLP methods. There were no significant differences in the genotype, allele, or haplotype distributions in 3 analyzed SNPs of the FCN2 gene between children with "higher" and those with "lower" caries experience as well as between children with caries experience and caries-free children. In conclusion, we did not find any association of FCN2 promoter polymorphisms at positions -986, -602, and -4 with dental caries in Polish children.

RESUMEN

Yeast-like fungi and gram-negative bacilli are the most frequent potential pathogens of the respiratory tract isolated from the denture plaque of patients with chronic obstructive pulmonary disease (COPD). Dominant species among yeast-like fungi are Candida albicans and Candida tropicalis. Significant frequency is also exhibited by Klebsiella pneumoniae and Klebsiella oxytoca. The purpose of this study was to analyze genetic diversity of the strains of C. albicans, C. tropicalis, and Klebsiella spp. present in patients in stable phases of COPD. The analysis was conducted by the random amplified polymorphic DNA (RAPD) method on clinical strains isolated from patients with COPD and control patients in overall good health. Forty one strains of Candida albicans, 12 of Candida tropicalis, as well as 9 strains of K. pneumoniae and 7 of K. oxytoca were scrutinized. The dominant species in clinical material from COPD patients was Candida albicans with a substantial degree of variations of genetic profiles. On the basis of affinity analysis, 19 genetic types were identified within this strain. An analysis of the banding patterns among C. tropicalis strains indicated the existence of 6 genetic types. A considerable diversity of genetic profiles among Klebsiella spp. also was established. The genotype diversity of Klebsiella spp. strains may indicate the endogenic character of the majority of infections, regardless of the therapy applied for the underlying condition.

RESUMEN

Culturing strains from clinical samples is the main method to diagnose invasive pulmonary aspergillosis. Detecting the galactomannan antigen in serum samples is an auxiliary examination. The goal of this study was to determine the frequency with which Aspergillus fumigatus was cultured in clinical samples taken from patients hospitalized in the the Infant Jesus Teaching Hospital in Warsaw, Poland, in the period of 2013-2014. Specimens from the respiratory tract and blood were cultured for mycological and serological assessments. Strain isolation was performed in chloramphenicol Sabouraud agar. Species identification was based on morphological traits in macro-cultures and on microscopic examination. The galactomannan antigen was detected by ELISA method. Out of 2000 clinical samples with positive mycological results, 200 were obtained from the respiratory tract. A. fumigatus was cultured in 13 cases from the respiratory group. Ten cases were cultured out of tracheal aspirates and three from bronchoalveolar lavage fluid. The galactomannan antigen was detected in a serum sample from only one out of the 13 patients with cultures positive for A. fumigatus. It also was detected in serum samples of three other patients in whom A. fumigatus culture yielded a negative result. We conclude that culture-confirmed invasive pulmonary aspergillosis represents a scarce finding. A. fumigatus cultured from clinical samples may not always be confirmed by ELISA assay and vice versa a positive ELISA result does not attest the successful culture.

RESUMEN

Aim: The purpose of this study was to analyse vaccine refrigerator and vaccine management in primary care and to identify physician- and practice-related influencing factors. Background: Adequate cooling of vaccines in a temperature range of 2-8°C is essential to assure vaccine effectiveness. Studies from various countries have demonstrated cooling chain problems. We surveyed general practitioners about the quality of their vaccine refrigerator and vaccine management and aimed at identifying physician- and practice-related influencing factors. Methods: A cross-sectional, web-based questionnaire survey was performed among 3 physician populations in primary care: a 10% random sample of general practitioners (n=954), all teaching physicians of the Universities Duisburg-Essen (n=221) and Halle-Wittenberg (n=92). Surveyed were items on the following 6 aspects: (1) responsibilities within practice teams, (2) vaccine ordering and storing, (3) criteria for the vaccine pre-selection, (4) stocking system inside the refrigerator, (5) wrapping, and use of stocking boxes, (6) refrigerator and temperature control. The quality indicator "comprehensive refrigerator management" was defined to include 4 aspects: (1) separate refrigerator, (2) written temperature documentation (temperature-logbook), (3) regular storage control (wrapping, temperature and expiration date), and (4) storage in original wrappings. Results: A total of 278 physicians participated in the survey (22%). Of these, 80% had a separate refrigerator, 52% reported written temperature documentation, 93% documented regular storage control addressing vaccine wrappings, temperature and expiration dates, and 95% reported vaccine storage in original card box wrappings. A "comprehensive refrigerator management" was realised by 42% of the practices. This indicator was reached more frequently by practices with 3 or more physicians (p=0.01) and those with an additional qualification in travel medicine (p=0.036). Conclusion: Our survey showed good results for most aspects of the refrigerator and vaccine management but room for improvement with regard to temperature documentation.

RESUMEN

BACKGROUND: Recent meta-analyses of resting-state networks in major depressive disorder (MDD) implicate network disruptions underlying cognitive and affective features of illness. Heterogeneity of findings to date may stem from the relative lack of data parsing clinical features of MDD such as phase of illness and the burden of multiple episodes. METHOD: Resting-state functional magnetic resonance imaging data were collected from 17 active MDD and 34 remitted MDD patients, and 26 healthy controls (HCs) across two sites. Participants were medication-free and further subdivided into those with single v. multiple episodes to examine disease burden. Seed-based connectivity using the posterior cingulate cortex (PCC) seed to probe the default mode network as well as the amygdala and subgenual anterior cingulate cortex (sgACC) seeds to probe the salience network (SN) were conducted. RESULTS: Young adults with remitted MDD demonstrated hyperconnectivity of the left PCC to the left inferior frontal gyrus and of the left sgACC to the right ventromedial prefrontal cortex (PFC) and left hippocampus compared with HCs. Episode-independent effects were observed between the left PCC and the right dorsolateral PFC, as well as between the left amygdala and right insula and caudate, whereas the burden of multiple episodes was associated with hypoconnectivity of the left PCC to multiple cognitive control regions as well as hypoconnectivity of the amygdala to large portions of the SN. CONCLUSIONS: This is the first study of a homogeneous sample of unmedicated young adults with a history of adolescent-onset MDD illustrating brain-based episodic features of illness.

RESUMEN

UNLABELLED: The study was undertaken to verify the antimicrobial activity of Lavandula angustifolia hydrosols in moisturizing body gels. The inhibition efficacy of four lavender hydrosols (obtained from fresh or dry herbs or flowers) was tested against Staphylococcus aureus ATCC 6538, Escherichia coli ATCC 1627, Candida sp. LOCK 0008 and Aspergillus niger ATCC 16404 in compliance with the standards of the European Pharmacopoeia Commission. Although the tested hydrosols did not express any remarkable antimicrobial action when tested via the macrodilution method, they show preservative activity in cosmetic preparations. Criterion A for fungi was fulfilled for the cosmetic formulation containing dried flower hydrosol (reduction of the inoculum by two logarithmic units within 14 days with no increase up to the 28th day) and Criterion B for bacteria E. coli and Staph. aureus (reduction of the inoculum by three logarithmic units within 14 days with no increase up to the 28th day). The fresh herb lavender hydrosol in the cosmetic formulation was regarded as the second one effectively satisfying Criterion B for bacteria, but its activity against fungi was below the acceptance value set out in the official regulations. Lavender hydrosols used as a replacement for water phase in cosmetics may contribute to maintaining microbiological stability of cosmetic formulations. SIGNIFICANCE AND IMPACT OF THE STUDY: The presented research proved antimicrobial activity of hydrosols obtained from fresh or dried Lavandula angustifolia herbs or flowers in moisturizing body gel. The study shows the usefulness of lavender hydrosols as a natural, ecologically friendly component of cosmetics with potential preservative activity in formulations. Hydrosols are commonly regarded as waste in the production of essential oils. The use of lavender hydrosols in the cosmetic industry as a replacement for water phase in cosmetics may not only result in expenses reduction for chemical stabilizers and preservatives but also in substantial decrease in sewage disposal.

RESUMEN

In the past years opportunistic fungal infections have seriously increased, mainly in immunocompromised patients. The aim of the study was to determine the prevalence of yeast-like fungi in invasive candidiasis and to estimate its susceptibility to chosen antifungal agents. One hundred and sixty strains of yeast-like fungi were cultured from various clinical material: samples from lower respiratory tract, blood, the peritoneal cavity and others. The susceptibility tests were established according to the quantitative E-test method. The Candida genus represented the main etiological factor of invasive candidiasis. The predominant species were: C. glabrata (71/160), C. albicans (34/160), C. krusei (17/160), C. tropicalis (14/160). All tested strains were the most resistant to itraconazole. Candida glabrata presented the 100% susceptibility to amphotericin B and caspofungin and was the least susceptible to itraconazole, posaconazole and voriconazole. Candida albicans was the most susceptible species to all antymicotics.

RESUMEN

Ciprofloxacin hydrochloride (CIP) is a broad-spectrum synthetic antibiotic often found in domestic sewage and industrial waste due to the inefficiency of conventional treatments. Given the potential risk of drug accumulation, this study presents coatings of titanium dioxide nanotubes (TiO2) doped with different bismuth (Bi) concentrations to degrade CIP through photocatalytic and photoelectrochemical processes. Characterization studies revealed that bismuth (Bi) doping affected the morphology of the materials, with concentrations of 0.01 and 0.05 mol L-1, resulting in collapsed materials with a smaller active surface area. Photocatalysis tests for all the materials exhibited a similar degree of efficiency to photolysis, approximately 33%. Ecotoxicity tests using the biomarkers Lactuca sativa L., Lemna minor, and Artemia salina indicated that, although they were similar to photolysis in terms of efficiency, the effluents generated when employing the doped catalysts showed lower levels of toxicity, with the best results achieved for the material doped with 0.005 mol L-1 of Bi, with a toxicity level approximately 40% lower. Photoelectrocatalysis proved to be the most efficient CIP degradation technique. The highest degradation rate was observed for materials doped with 0.005 mol L-1 of Bi, with an efficiency of 46%, which is 1.4 times more efficient than photolysis. These results demonstrate that materials doped with low amounts of Bi can be effectively used as photoanodes for drug degradation, as their performance is superior, and the final product generated exhibits low toxicity to living organisms.
