Parental assessment of infantile hemangioma cosmetic clinical outcomes: results of the Spanish Hemangioma Nationwide Prospective Cohort.

BACKGROUND: Functional impairment is the main consideration when it comes to choosing therapy for infantile hemangiomas (IH). However, since most hemangiomas are treated for cosmetic reasons, it is important to know the cosmetic outcome assessed by the parents. OBJECTIVE: To evaluate the aesthetic outcomes of IH, considering the characteristics of the lesions and the treatments used. PATIENTS AND METHODS: The Spanish Infantile Hemangioma Nationwide Prospective Cohort (2016-2022) recruited all consecutive patients diagnosed with IH in 12 Spanish hospitals. The children included had 2 photos of the IH lesion (at both baseline and at the end of the study). A panel of parents blindly assessed all available photos using a scale from 0 (worst cosmetic outcomes) to 10 (best cosmetic outcomes). The different scores -both before and after treatment-as well as the outcomes percent considered excellent (> 9) were described and compared. We analyzed the effect of receiving different therapies and performed causal model analyses estimating the mean treatment effect of parents' assessments. RESULTS: The median follow-up was 3.1 years. A total of 824 photos were evaluated. Baseline aesthetic impact was higher in the propranolol group vs the topical timolol and observation treatment groups (1.85 vs 3.14 vs 3.66 respectively; p < 0.001). After treatment, the aesthetic impact was similar between both treatment groups (7.59 vs 7.93 vs 7.90; p > 0.2). The causal model could only be applied to the comparison between topical timolol and observation, revealing no differences whatsoever. CONCLUSION: This is the first prospective cohort to analyze the aesthetic outcome of IH. The final aesthetic results of the 3 therapies were similar, with nearly 40% of patients achieving excellent aesthetic outcomes.

Real-World Clinical, Psychosocial and Financial Burden of Atopic Dermatitis: Results from the Spanish Cohort of the MEASURE-AD Trial. / Carga clínica, psicosocial y económica de la dermatitis atópica en vida real: resultados de la cohorte española del estudio MEASURE-AD.

BACKGROUND: Atopic dermatitis (AD) is one of the most prevalent skin diseases, but there are numerous knowledge gaps surrounding the impact this disease has on quality of life (QoL), mental health, and out-of-pocket expenses involved in the management of AD. The available scientific evidence on the multidimensional burden of AD is usually based on studies with measures reported by patients themselves. METHODS: In this context, the MEASURE-AD trial was developed as a cross-sectional, multicenter, multinational trial using patient- and physician-reported measures to characterize the multidimensional burden of AD in adults with moderate-to-severe AD. RESULTS: This paper presents the results of the Spanish cohort. We found that Spanish adults with moderate-to-severe AD and high EASI score (21.1-72) had a significantly increased disease burden, high severity of symptoms such as itch and sleep disturbances, impaired mental health and QoL, higher use of health care resources, and more out-of-pocket expenses than patients with low EASI scores (0-7 or 7.1-21). CONCLUSIONS: This study provides information to better understand disease burden, and identify aspects to be improved in the management of AD.

Relationship between inflammation and oxidative stress and its effect on multiple sclerosis.

INTRODUCTION: This paper highlights the relationship of inflammation and oxidative stress as damage mechanisms of Multiple Sclerosis (MS), considered an inflammatory and autoimmune disease. DEVELOPMENT: The oxidative stress concept has been defined by an imbalance between oxidants and antioxidants in favor of the oxidants. There is necessary to do physiological functions, like the respiration chain, but in certain conditions, the production of reactive species overpassed the antioxidant systems, which could cause tissue damage. On the other hand, it is well established that inflammation is a complex reaction in the vascularized connective tissue in response to diverse stimuli. However, an unregulated prolonged inflammatory process also can induce tissue damage. CONCLUSION: Both inflammation and oxidative stress are interrelated since one could promote the other, leading to a toxic feedback system, which contributes to the inflammatory and demyelination process in MS.

Ovarian cancer prevention by opportunistic salpingectomy is a new de facto standard in Germany.

PURPOSE: The most prevalent and aggressive subtype of epithelial ovarian carcinoma (EOC), high-grade serous carcinoma (HGSC), originates in many cases from the fallopian tubes. Because of poor prognosis and lack of effective screening for early detection, opportunistic salpingectomy (OS) for prevention of EOC is being implemented into clinical routine in several countries worldwide. Taking the opportunity of a gynecological surgery in women at average cancer risk, extramural fallopian tubes are completely resected preserving the ovaries with their infundibulopelvic blood supply. Until recently, only 13 of the 130 national partner societies of the International Federation of Obstetrics and Gynecology (FIGO) have published a statement on OS. This study aimed to analyze the acceptance of OS in Germany. METHODS: (1) Survey of German gynecologists in 2015 and 2022 by the Department of Gynecology of the Jena University Hospital in co-operation with the Department of Gynecology at Charité-University Medicine Berlin with support of NOGGO e. V. and AGO e. V. (2) Salpingectomy numbers in Germany for years 2005-2020 as retrieved from the Federal Statistical Office of Germany (Destatis). RESULTS: (1) Survey: Number of participants was 203 in 2015 and 166 in 2022, respectively. Nearly all respondents (2015: 92%, 2022: 98%) have already performed bilateral salpingectomy without oophorectomy in combination with benign hysterectomy with the intention to reduce the risk for malignant (2015: 96%, 2022: 97%) and benign (2015: 47%, 2022: 38%) disorders. Compared to 2015 (56.6%), considerably more survey participants performed OS in > 50% or in all cases in 2022 (89.0%). Recommendation of OS for all women with completed family planning at benign pelvic surgery was approved by 68% in 2015 and 74% in 2022. (2) Case number analysis: In 2020, four times more cases of salpingectomy were reported by German public hospitals compared to 2005 (n = 50,398 vs. n = 12,286). Of all inpatient hysterectomies in German hospitals in 2020, 45% were combined with salpingectomy, and more than 65% in women at the age of 35 to 49 years. CONCLUSION: Mounting scientific plausibility regarding involvement of fallopian tubes in the pathogenesis of EOC led to change of clinical acceptance of OS in many countries including in Germany. Case number data and widespread expert judgment demonstrate that OS has become a routine procedure in Germany and a de facto standard for primary prevention of EOC.

Media Contributions to a Chesapeake Bay Watershed Collective Identity? A Tale of Three Cities.

Although collective action is needed to address many environmental challenges, it cannot proceed in the absence of collective identity, that is, evidence of group belongingness expressed in or via communicative behavior. This study looked for evidence of a collective identity in newspaper articles that referenced the Chesapeake Bay Watershed. The data were drawn from local papers published in municipalities located at the headwaters of the Susquehanna River, midway down the Susquehanna, and where the river meets the Bay. Computerized content analysis assessed the frequency with which the Chesapeake Bay and watershed were mentioned alongside a set of keywords thought to represent different facets of identity (e.g., agriculture, fishing, swimming). The results showed substantial variation in frequency across time and place but low absolute levels of coverage of the Bay and the watershed. Multidimensional scaling revealed different structures to collective identity as a function of place. These differences in content may be attributable to varying demographic and environmental characteristics along with proximity to the Bay. But, to the extent that media contribute to collective identity among residents of the watershed at all, they do so in a complex and heterogeneous manner.

Data supporting the in situ synthesis by organometallic method of Vulcan supported PdNi nanostructures for hydrogen evolution reaction in alkaline solution.

This document presents the supporting information for the evaluation of the role of Ni amount during the in situ synthesis of vulcan supported PdNi nanostructures using an organometallic approach for hydrogen evolution reaction in alkaline medium [1]. The data here presented included analysis of deconvolution during structural characterization, chemical composition and transmission electron microscopy. The information also contains complement data of cyclic voltammograms during activation in alkaline media. Supplement data of electrochemical impedance spectroscopy measurements at two different overpotentials (-100 and -300 mV) and temperatures on the onset potential for hydrogen evolution reaction (HER) are also showed in this paper. The files can be used as a reference to determinate the effect of adding different in situ amount of Ni to Pd/C catalysts in presence of 2 equivalents of hexadecylamine (HDA) in order to improve the electrochemical performance on HER using an adjusted organometallic method. The data provided in this article have not been previously published and are available to enable critical or extended analyses.

Efficacy and safety of oral sirolimus for high-flow vascular malformations in real clinical practice.

BACKGROUND: Vascular malformations are a complex pathology with few treatment options. In previously published studies, oral sirolimus (rapamycin) has shown promising results in the treatment of low-flow vascular malformations, but its usefulness in high-flow vascular malformations is controversial. AIM: To evaluate the efficacy and safety of sirolimus for the treatment of high-flow vascular malformations in real-life practice. METHODS: In a unit specializing in vascular anomalies, patients treated with oral sirolimus for high-flow vascular malformations were located by consulting the drug dispensations. Reviewing the electronic medical records, data on patient demographics, vascular malformation characteristics, treatments, toxicity and clinical course were collected and statistically analysed. RESULTS: Nine patients with vascular malformations were included: eight had arteriovenous malformation and one had arteriovenous fistula. Six of these malformations were isolated while three were part of a syndrome. Sirolimus was initiated at a dosage of 1-4 mg/day to be taken as a single dose. Partial response was observed in eight of the nine patients (88.9%) with high-flow vascular malformation, while worsening was observed in the remaining patient. The treatment was well tolerated and at the most recent follow-up, five patients remained on treatment with oral sirolimus. CONCLUSION: Our results show that oral sirolimus is a well-tolerated therapeutic option, with an excellent safety profile, which can be useful in the long-term stabilization of patients with high-flow vascular malformations. Single-daily dosage may improve long-term adherence to treatment without worsening its effectiveness.

Baseline description of the Spanish Academy of Dermatology infantile haemangioma nationwide prospective cohort. Comparison of patients treated with propranolol in routine clinical practice with previous pivotal clinical trial data. / Descripción basal de la cohorte prospectiva de hemangioma infantil a nivel nacional de la Asociación Española de Dermatología. Comparación de los pacientes tratados con propranolol en la práctica clínica rutinaria y los datos de un ensayo clínico pivotal previo.

BACKGROUND: There are several therapeutic options for infantile haemangiomas (IH). Propranolol is used according to a pivotal trial. We aimed to describe the characteristics of IH in clinical practice, including the therapies used, and to compare the characteristics of patients treated with propranolol with those of the trial to assess its external validity. METHODS: Consecutive patients attending 12 Spanish hospitals from June 2016 to October 2019 were included (n=601). RESULTS: The mean age was 3.9 (SD:1.9) months, with a 2:1 female-to-male ratio. Most IHs were localized (82%, 495), superficial (64%, 383) and located in the face (25%, 157) and trunk (31%, 188). Median size was 17 (IR: 10-30) x 12 (IR: 7-20) mm. Complications were found in 16 (3%) patients. Treatment was initiated for 52% (311). Most patients received timolol (76%, 237); propranolol was reserved for complications or high-risk IHs. Aesthetic impairment was the main reason for starting therapy (64%, 199). Several characteristics of the patients and IHs treated with propranolol are similar to those of the pivotal clinical trial, but 1/3 of IHs did not reach the minimum diameter to meet the inclusion criteria, and important prognostic information was not reported. CONCLUSIONS: As most patients receive treatment for aesthetic impairment, there is a need to better understand the aesthetic results of therapies and to increase evidence on the use of timolol, which is currently the most common therapy. Propranolol is being used in a population generally similar to that of the trial; however, this statement cannot be definitely confirmed.

Candidate Interneurons Mediating the Resetting of the Locomotor Rhythm by Extensor Group I Afferents in the Cat.

Sensory information arising from limb movements controls the spinal locomotor circuitry to adapt the motor pattern to demands of the environment. Stimulation of extensor group (gr) I afferents during fictive locomotion in decerebrate cats prolongs the ongoing extension, and terminates ongoing flexion with an initiation of the subsequent extension, i. e. "resetting to extension". Moreover, instead of the classical Ib non-reciprocal inhibition, stimulation of extensor gr I afferents produces a polysynaptic excitation in extensor motoneurons with latencies (∼3.5-4.0 ms) compatible with 3 interposed interneurons. We assume that some interneurons in this pathway actually belong to the rhythm-generating layer of the locomotor Central Pattern Generator (CPG), since their activity was correlated to a resetting of the rhythm. In the present work fictive locomotion was (mostly) induced by i.v. injection of nialamide followed by l-DOPA in paralyzed cats following decerebration and spinalization at C1 level. In some experiments, we extended previous observations during fictive locomotion on the emergence and locomotor state-dependence of polysynaptic excitatory postsynaptic potentials from extensor gr I afferents to ankle extensor motoneurons. However, the main focus was to record location and properties of interneurons (n = 62) that (i) were active during the extensor phase of fictive locomotion and (ii) received short-latency excitation (mono-, di- or polysynaptic) from extensor gr I afferents. We conclude that the interneurons recorded fulfill the characteristics to belong to the neuronal pathway activated by extensor gr I afferents during locomotion, and may contribute to the 'resetting to extension' as part of the locomotor CPG.

Data that support the structural, chemical and morphological characterization and its influence on the electrochemical performance of stabilized PdxPt1-x alloys as electrode materials for methanol oxidation in alkaline medium.

Structural, compositional, morphological and electrochemical characterization are important to determinate the influence of platinum in the methanol oxidation in alkaline media. These data and analysis support the research article catalytic performance of alloyed PtxPd1-x nanostructures supported on Vulcan XC-72R for the methanol oxidation in alkaline medium [1]. The data here presented included changes in the chemical composition, structure and microstructure. Also, complement data of cyclic voltammograms during activation in alkaline media as well as in presence of 1 M CH3OH to observe CO tolerance and Electrochemical Impedance Spectroscopy measurements at two different overpotentials (0.2 and 0.3 mV) on the onset potential for methanol electro-oxidation are published in this paper. The data can be used as a reference to determinate the effect of added different amounts of Pd to Pt/C catalysts, using an organometallic compounds method and octylamine as stabilizer. The data provided in this article have not been previously published and are available to enable critical or extended analyses.

An interesting increase in immediate and residual efficacy of a trade mark of alcoholic 2% chlorhexidine gluconate, with and without dye, has been demonstrated by an in vitro study with ATCC micro-organisms and strains isolated from ICU patients.

AIM: ChloraPrep™ (CHP) is a clear solution of 2% (w/v) chlorhexidine (CHG) in 70% (v/v) isopropyl alcohol (IPA) administered with a specially designed sterile single-use applicator in which a tinting agent can be added to the CHP solution upon activation of applicator immediately prior to patient skin preparation (CHP+T). This study investigated whether the immediate and residual efficacy of CHP vs CHP+T and a stock solution of 2% CHG in 70% IPA varied, and whether CHP was compromised by the addition of the dye. METHODS AND RESULTS: We compared the immediate and residual activity (in 1 min) of 70% IPA with that of 2% CHG in 70% IPA stock solution prepared in the laboratory against CHP+T and CHP, against 22 micro-organisms (5 ATCC and 18 clinical isolates) on germ-carriers. CHP and CHP+T demonstrated superior immediate and residual efficacy compared to the 70% IPA plus 2% CHG in 70% IPA stock solutions. Each antiseptic tested showed greater efficacy against the Gram-positive bacteria than against the Gram-negative bacteria. However, their antimicrobial effect on yeasts was even lower. CONCLUSIONS: CHP and CHP+T have superior immediate and residual efficacy compared to stock 70% IPA and 2% CHG in 70% IPA solutions, and CHP+T is not affected by the tinting agent. SIGNIFICANCE AND IMPACT OF THE STUDY: ChloraPrep is a product which can be stained just before use. We have demonstrated that the immediate and residual efficacy of the antimicrobial solution is not compromised by the dye. The efficacy of CHP is greater against bacteria than against yeasts obtained from ICU patients. Interestingly, CHP is more effective against bacteria than a formula made in the laboratory with the same basic components (2% chlorhexidine and 70% IPA). The intermittent heat sterilization process of the commercial preparation might hypothetically have improved the residual activity of the CHP solutions.

Situation, challenges, and SEOM recommendations for the future of undergraduate education in Oncology in Spain.

PURPOSE: The Spanish Society of Medical Oncology (SEOM, for its Spanish acronym) would like to attest to the relevance of training in Oncology as part of the undergraduate education in Medicine program and issue recommendations to improve said training, with the aim of responding better to the challenges that cancer poses to our society. MATERIALS AND METHODS: The curricula of 42 schools of medicine were reviewed with interviews with at least one teaching medical oncologist from each faculty. The qualitative and opinion analysis was completed by means of an online questionnaire targeting lecturers, resident tutors, and residents in Medical Oncology (MO), enabling the detection of needs and areas for improvement at an organizational level and in terms of skill acquisition. RESULTS: While the number of medical schools with a specific, mandatory program in MO has grown by up to 90%, it has not been accompanied by an increase in independent programs. Instead, they largely consist of programs shared with other specialties (61% of the medical faculties). In most of the undergraduate education programs, Oncology contents are fragmented and approached from the perspective of each organ system. CONCLUSIONS: Despite the positive evolution in recent years, the heterogeneity in Oncology contents during undergraduate education training continues to be remarkable. Cross-sectional programs with an integral vision, taught in the final years of undergraduate medical education would be desirable. Among the recommendations for improvement of training in Medical Oncology, the SEOM proposes that updated, theoretical content be incorporated and clinical practice in Medical Oncology departments be promoted.

Clinical and Epidemiological Characteristics of Merkel Cell Carcinoma in a Series of 38 Patients. / Características clínico-epidemiológicas del carcinoma de células de Merkel en una serie de 38 pacientes.

BACKGROUND: Merkel cell carcinoma is a rare yet aggressive cutaneous tumor with a poor prognosis. Few studies have analyzed series of patients from the same hospital. METHODOLOGY: We performed a retrospective, descriptive, observational study of all patients diagnosed with Merkel cell carcinoma at a tertiary care hospital between 2002 and 2017. We recorded epidemiological, clinical, and histologic data and information on treatments and survival. For analysis, the sample was divided into 2 groups from different periods: 2002-2009 and 2010-2017. We performed survival analysis using Kaplan-Meier curves and multivariate analysis using a Cox proportional hazards model. RESULTS: Thirty-eight patients (24 men and 14 women) with a mean age of 77.76 years were included. Mean follow-up time was 30.11 months. On comparing 2010-2017 with 2002-2009, we observed a 116% increase in the number of Merkel cell carcinoma cases (26 vs. 12), an older mean age at diagnosis (80.92 vs. 70.92 years, P<.05), and an increase in lesions located on the trunk and lower limbs (0% vs. 34.62%). Eleven patients died of Merkel cell carcinoma. Overall survival was 78.2% at 12 months and 69.3% at 24 months. In the univariate analysis, age over 70 years and lymph node involvement were associated with mortality, while tumor location on the upper extremities and wide surgical excision were associated with improved survival. Only lymph node involvement retained its prognostic significance in the multivariate analysis. CONCLUSIONS: In this series, we observed that Merkel cell carcinoma has become more common in recent years and is now diagnosed at an older age and found in new anatomic locations.

Analyzing College Students' Social Media Communication Apprehension.

Research has shown that college students are heavy users of social media. Yet, very little has looked at the connection between college students' social media use and communication apprehension (CA). Due to the shortage of research concerning CA and social media, this study aims to test the relationship between social media CA and introversion in relationship to social media use and social media addiction. To test these relationships, 396 undergraduate students were surveyed. The survey consisted of instruments used to measure the individuals' levels of social media use, social media addiction, introversion, and CA. After conducting multiple linear regressions, it was determined that there was a negative relationship between social media CA and introversion with (1) social media use and (2) social media addiction. Results indicated that social media CA was significantly related to social media addiction. These findings suggest that college students might gravitate toward social media to communicate rather than face-to-face communication.

Empowerment in Dermatology. / Empoderamiento y Dermatología.

The term empowerment refers to any process that facilitates behavioral changes and encourages responsibility and making informed choices. The concept has been applied mainly to help patients with chronic conditions achieve therapeutic goals. The aim of the approach in health care is to enhance self-caring and self-efficacy. The term derives from the English verb to empower meaning "to give (someone) the authority or power to do something" or "to make an individual or a group stronger or more powerful". One of the responsibilities of health professionals is to improve patients' knowledge and their ability to choose between the different alternatives available to them so that they can act accordingly. In this article, we review the various definitions of the term empowerment, the tools used to measure patient empowerment, the implications of the concept for the management of chronic disease, and its use in dermatological conditions.

Incidence and risk factors of superficial and deep vein thrombosis associated with peripherally inserted central catheters in children.

Essentials Pediatric studies on peripherally inserted central catheter (PICC)-related thrombosis are scarce. This study analyzes incidence and risk factors for PICC-related venous thrombosis in children. PICC-related thrombosis is a common, and nearly always, asymptomatic complication. Echo-guided insertion and a catheter to vein ratio < 0.33 may notably decrease this complication. SUMMARY: Background Upper-extremity venous thrombosis is associated with the use of peripherally inserted central catheters (PICCs). Few pediatric studies have focused on this issue. Objectives To determine the incidence and risk factors for PICC-related superficial vein thrombosis (SVT) and deep vein thrombosis (DVT) in children. Patients/methods An observational follow-up cohort study was conducted at a single hospital between June 2012 and June 2015. All patients receiving a PICC were enrolled and followed up, with weekly Doppler ultrasound examination of the catheterized limb until PICC removal. Patient, procedural and follow-up data were analyzed. Results In the study period, 265 PICCs were inserted (median age of patients 6.5 years, interquartile range [IQR] 2.4-13 years; median weight 20 kg, IQR 11-38 kg; 54% males; 67.9% chronically ill), and patients were followed up for a total of 9743 days. The median indwelling time was 21 days (IQR 12-37 days). During follow-up, 88 (33.2% of insertions) PICC-related thromboses (incidence rate [IR] 9.03 per 1000 catheter-days) were diagnosed, 66 (24.9%) as isolated SVT, seven (2.6%) as isolated DVT, and 15 (5.7%) as SVT with associated DVT (IR 6.78, 0.71 and 1.54 per 1000 catheter-days, respectively). Only 9.9% of patients with SVT and 18.2% of those with DVT were symptomatic. The main risk factors for PICC-related SVT and DVT were a catheter/vein ratio of > 0.33 and thrombosis of the catheterized superficial vein, respectively. Conclusions PICC-related thrombosis is a common and nearly always asymptomatic complication in children, the SVT rate being approximately three times higher than the DVT rate. Optimal vein and catheter selection, yielding the lowest possible catheter/vein ratio, may decrease the rate of PICC-related thrombosis.

Vinculin expression in MC3T3-E1 cells in response to mechanical stimulus.

Loading frequency is known to influence the expression of the focal adhesions of the adherent cells. A small cyclical tensile force was transmitted to mouse pre-osteoblast MC3T3-E1 cells through PDMS substrates of varying stiffness. Changes in cell behavior with respect to proliferation and characteristics of focal adhesions were quantified through immunofluorescence labeling of vinculin. Amount of inactive vinculin was higher on substrates subjected to cyclic stimulation when compared with the results of the static substrates, whereas the number and area of focal adhesion points underwent a reduction. Inactive vinculin appears as a cloud in the cytoplasm in the vicinity of the nucleus.
