RESUMEN
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.

AIM: The study evaluated the efficacy and potential erosion of non-peroxide strips compared to hydrogen peroxide (HP) whitening strips (WSs). METHODS: Color evaluation samples (N=64) were distributed into four groups and treated according to manufacturer's directions. NC: Negative control treated with water; BT: Non-peroxide Brilliant Dissolving Strips; FM: Non-peroxide Fancymay Teeth WSs; WS: Crest 3D Brilliance HP White Strips. A contact-type spectrophotometer was used to measure color at baseline (T1), 1-day posttreatment (T2), and 1-week posttreatment (T3). Teeth were cut to a rectangular block for micro-CT erosion assessment. The samples (N=30) were divided into five groups. In addition to the four groups for color assessment, a positive control (PC) treated with 0.25% citric acid was added. The samples were scanned, reconstructed, and measured for erosion depth using a micro-CT analysis program software. Kruskal-Wallis test was used to determine differences in color change and erosion depth among the groups. Tests of hypotheses were two-sided with an alpha level of 0.05. RESULTS: The mean ΔE*ab at 1-day/1-week posttreatment were 2.4/2.5, 2.8/2.9, 2.8/3.2, and 8.6/11.0 for NC, BT, FM, and WS, respectively. There was a statistically significant difference for ΔE*ab at 1-day and 1-week posttreatment (p<0.001). Group WS had the highest color change, while the other three groups did not differ from each other (p>0.05). Mean erosion depths in microns were 0.52, 0.58, 0.42, 0.49, and 29.55 for NC, BT, FM, WS, and PC, respectively. There was a statistically significant difference among the groups (p=0.004). Group PC had the greatest erosion, while the other groups had negligible erosion that did not differ from each other (p>0.05). CONCLUSION: Peroxide WSs had superior whitening efficacy compared to non-peroxide strips. None of the tested products compromised tooth structure integrity through enamel erosion.

Understanding the recovery of whale populations is critical for developing population-management and conservation strategies. The southern right whale (SRW) Eubalena australis was one of the baleen whale species that has experienced centuries of exploitation. We assess here for the first time the population dynamics of the SRW from the southwestern Atlantic Ocean at the regional level to measure numerically the effect of whaling and estimate the population trend and recovery level after depletion. We reconstructed the catch history of whaling for the period 1670-1973 by an extensive review of different literature sources and developed a Bayesian state-space model to estimate the demographic parameters. The population trajectory indicated that the pre-exploitation abundance was close to 58,000 individuals (median = 58,212; 95% CI = 33,329-100,920). The abundance dropped to its lowest abundance levels in the 1830s when fewer than 2,000 individuals remained. The current median population abundance was estimated at 4,742 whales (95% CI = 3,853-6,013), suggesting that the SRW population remains small relative to its pre-exploitation abundance (median depletion P2021 8.7%). We estimated that close to 36% of the SRW population visits the waters of the Península Valdés, the main breeding ground, every year. Our results provide insights into the severity of the whaling operation in the southwestern Atlantic along with the population´s response at low densities, thus contributing to understand the observed differences in population trends over the distributional range of the species worldwide.

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.
RESUMEN
BACKGROUND AND OBJECTIVE: Body dysmorphic disorder (BDD) is a mental disorder that is difficult to diagnose, causes a lot of suffering and is more prevalent in dermatology patients than in the general population. Our objective was to screen for possible cases of BDD in patients with acne and to determine the prevalence according to DSM-IV and DSM-5 criteria, as well as to analyse the relationship between dermatological and sociodemographic variables. METHODS: A total of 245 patients diagnosed with acne in 11 dermatological centres in Spain were included in the study by members of the Aragon Psychodermatology Research Group and Spanish Research Group of Psychiatric Dermatology. We used the Body Dysmorphic Disorder Questionnaire (BDDQ) as a screening tool. RESULTS: In our sample, we obtained a prevalence for BDD of 10.6% (95% CI: 7.6-13.6%). The prevalence was the same with DSM-IV or DSM-5 criteria. Possible cases of BDD were predominantly women (P = 0.021), and 56% had non-inflammatory lesions vs. 30% of negative patients (P = 0.002). Positive patients as possible cases of BDD spent more than two hours on average a day worrying about their appearance. Most people only worried about one part of their body (86%), and in 95% of the cases, the part of their body that worried them was the face. The three most frequent compulsive behaviours in patients who screened positive for BDD were mirror checking (90.7%), camouflaging (79.1%) and using make-up (72.1%). CONCLUSIONS: As a consequence of the high prevalence of possible cases of BDD in patients with acne observed in our study, there is a need for dermatologists to screen for BDD so that they can be referred to a mental health unit to confirm the diagnosis and be offered treatment to reduce the progression of psychosocial deterioration and the development of comorbid disorders.

RESUMEN: el tratamiento de elección del carcinoma no microcítico de pulmón es la cirugía de resección pulmonar. El objetivo principal de nuestro trabajo fue determinar la actividad física de los pacientes sometidos a cirugía de cáncer de pulmón (CP) y si esta medición puede ser un predictor de las complicaciones en el postoperatorio. Material y métodos: estudio observacional prospectivo, con inclusión consecutiva de pacientes con CP e indicación quirúrgica de la consulta monográfica del Hospital Macarena de Sevilla, desde octubre 2014 a octubre 2016. Se midió la actividad física previa a la cirugía mediante holter de actividad física o acelerómetro Armband® durante 5 días. Se recogieron las complicaciones postquirúrgicas, días de estancia media y mortalidad. Resultados: n: 56. La complicación más frecuente fue la fuga aérea (33,9%), seguida del derrame pleural (21,3%). El 48,2% presentaron al menos dos complicaciones. La mortalidad en el postoperatorio fue de 1,8%. La estancia media de 9,5 ± 1,4 días. Los niveles basales de actividad física fueron de 664,8 ± 323 min y el gasto energético total de 2.882,2 ± 485 kcal/día. La media de pasos/día realizados y de MET fue de 6.831,3 ± 3.834,7 y 1,3 ± 0,2, respectivamente. En cuanto a la relación del número de complicaciones con variables de actividad física, no se encontraron diferencias estadísticamente significativas. Discusión: los pacientes que van a someterse a cirugía de CP presentan niveles bajos de actividad física. Sin embargo, dichos niveles no se relacionan con la presencia de un mayor número de complicaciones
ABSTRACT: the main treatment for non-small cell lung cancer is lung resection surgery. The objective of our study was to determine the physical activity of patients undergoing lung cancer surgery and whether this measurement could be a predictor of complications in the postoperative period. Methods: Prospective observational study with consecutive inclusion of patients with lung cancer undergoing surgery of the pneumology medical practice of the Macarena Hospital of Seville from October 2014 to October 2016. Physical activity was measured prior to surgery by physical activity holter or Armband® accelerometer for 5 days. Postoperative complications, days of average stay and mortality were collected. Results: n: 56. The most frequent complication was leakage (33.9%), followed by pleural effusion (21.3%). 48.2% presented at least two complications. The mortality in the postoperative period was 1.8%. The average stay of 9.5 ± 1.4 days. The basal levels of physical activity were 664.8 ± 323 min and the total energy expenditure of 2882.2 ± 485 kcal / day. The mean of steps / day performed and MET was 6831.3 ± 3834.7 and 1.3 ± 0.2 respectively. Regarding the relationship of the number of complications with physical activity variables, no statistically significant differences were found. Discussion: Patients who underwent lung cancer surgery showed low levels of physical activity. However, these levels are not related to the a greater number of complications

BACKGROUND: Nail psoriasis disease is associated with an increased probability of psoriatic arthritis, and its clinical signs may have different correlates with the pathogenesis of adjacent bone destruction and have different prognostic value. Recent publications about psoriasis and nail psoriatic disease describe different ultrasonographic findings but the relationship between these ungueal alterations measured by ultrasonography and the presence of enthesopathy of the extensor digitorum has yet to be discovered. OBJECTIVE: To describe which ultrasonographic characteristics of nail psoriasis are associated with the presence of subclinical enthesopathy in patients with PsO and asymptomatic PsA. METHODS: Patients with psoriasis and asymptomatic psoriatic arthritis were included in the prospective study. Demographic, clinical data and PASI and NAPSI indexes were recorded of all the patients in the assessment visit. The US assessment included Achilles tendon, extensor digitorum tendon and US scan of the nail plate, nail matrix, nail bed and adjacent skin over nail matrix of the five nails of each hand. RESULTS: Forty-eight patients were included in the study; 33 of them presented ultrasound evidence of extensor digitorum tendon enthesopathy. Nails of the patients with subclinical enthesopathy had a higher NAPSI and skin thickness than the nails of the patients without subclinical enthesopathy (P = 0.047). Patients with asymptomatic enthesopathy had significantly thicker proximal nail folds (1.44 ± 0.312 vs. 1.23 ± 0.27, P = 0.023). Nail beds and matrices were also thicker but the differences were not statistically significant (1.77 ± 0.27 vs. 1.74 ± 0.21, P = 0.66, and 1.79 ± 0.28 vs. 1.67 ± 0.19, P = 0.10, respectively). No statistically significant differences in the trilaminar structure were found between both groups. Patients with and without asymptomatic enthesopathy of extensor digitorum tendons did not statistically differ as regards ultrasonographic alterations of the Achilles tendons (60.6% vs. 46.4%, P 0.368). CONCLUSION: Enthesopathy abnormalities can be detected by US in patients with psoriasis without musculoskeletal complaints frequently. There is a close relationship between subclinical enthesopathy of the extensor digitorum tendon and the presence of nail alterations. Further studies are required to research what implications have the presence of these ungual alterations measured by US, and how it affects later development of a PsA.

An understanding of the underlying processes and comprehensive history of population growth after a harvest-driven depletion is necessary when assessing the long-term effectiveness of management and conservation strategies. The South American sea lion (SASL), Otaria flavescens, is the most conspicuous marine mammal along the South American coasts, where it has been heavily exploited. As a consequence of this exploitation, many of its populations were decimated during the early 20th century but currently show a clear recovery. The aim of this study was to assess SASL population recovery by applying a Bayesian state-space modelling framework. We were particularly interested in understanding how the population responds at low densities, how human-induced mortality interplays with natural mechanisms, and how density-dependence may regulate population growth. The observed population trajectory of SASL shows a non-linear relationship with density, recovering with a maximum increase rate of 0.055. However, 50 years after hunting cessation, the population still represents only 40% of its pre-exploitation abundance. Considering that the SASL population in this region represents approximately 72% of the species abundance within the Atlantic Ocean, the present analysis provides insights into the potential mechanisms regulating the dynamics of SASL populations across the global distributional range of the species.

BACKGROUND: Infantile hemangiomas with minimal or arrested growth (IH-MAGs) are characterized by a proliferative component of <25% of its surface area. The co-occurrence of IH-MAGs and soft tissue anomalies is rare, and case series of this association are lacking. OBJECTIVE: We present 10 cases of IH-MAGs associated with soft tissue hypertrophy and describe their clinical features. METHODS: We reviewed all infantile hemangiomas with minimal or arrested growth seen between 2009 and 2016 in the dermatology clinic department at Hospital Santa Creu i Sant Pau, Barcelona. To collect more patients, we also requested cases from the Hemangioma Investigator Group and members of the Spanish Society of Vascular Anomalies. RESULTS: Ten patients had IH-MAGs associated with soft tissue hypertrophy; seven involving the arm and three involving the leg. All displayed a segmental pattern, a doughy and puffy texture and prominent surface veins. No significant asymmetries in limbs and no other visceral anomalies were observed at follow-up (range 15 months to 7 years). One patient reported coldness in the limb with infantile hemangioma, but RMI-angiography did not disclose a vascular malformation underneath the lesion. Ulceration was observed in three patients. The proliferative component in all IH-MAGs had faded at 1-year follow-up, while soft tissue hypertrophy and prominent vessels remained unchanged. CONCLUSIONS: In this first case series of IH-MAGS associated with soft tissue hypertrophy, soft tissue hypertrophy was not progressive and remained unchanged over time, unlike the proliferative component of classic infantile hemangioma. The origin of the prominent vessels and the higher ulceration risk are unknown; however, these findings are probably related to a minor disruption of local vessels not detected in imaging tests.

OBJECTIVES: To describe the medical and legal characteristics of sexual assault victims and to highlight which aspects of the medical examination may be associated with a conviction of the alleged offender. METHODS: This study included all women who consulted to the center for the victims of sexual assault in Nancy between 2008 and 2012 and who filed a complaint. Associations were evaluated with a logistic regression trying to explain the presence of a conviction at the end of the legal proceeding. RESULTS: Three hundred seventy-six victims were included. Following aspects were associated with a reduced probability of conviction: the use of psychoactive substances, the prescription of an antiretroviral therapy and the presence of more than one assailant. The prescription of pain killers were contrarily related to the conviction of an assailant. CONCLUSION: A detailed description, an interpretation of the physical injuries and the prescription of toxicological tests if needed are decisive in the outcome of the legal proceedings of victims of sexual assault. The education of populations at risk and the accompanying of the victims can reduce the delay of care and optimize the collection of evidence.

Ganodermataceae is a remarkable group of polypore fungi, mainly characterized by particular double-walled basidiospores with a coloured endosporium ornamented with columns or crests, and a hyaline smooth exosporium. In order to establish an integrative morphological and molecular phylogenetic approach to clarify relationship of Neotropical Amauroderma s.lat. within the Ganodermataceae family, morphological analyses, including scanning electron microscopy, as well as a molecular phylogenetic approach based on one (ITS) and four loci (ITS-5.8S, LSU, TEF-1α and RPB1), were carried out. Ultrastructural analyses raised up a new character for Ganodermataceae systematics, i.e., the presence of perforation in the exosporium with holes that are connected with hollow columns of the endosporium. This character is considered as a synapomorphy in Foraminispora, a new genus proposed here to accommodate Porothelium rugosum (≡ Amauroderma sprucei). Furtadoa is proposed to accommodate species with monomitic context: F. biseptata, F. brasiliensis and F. corneri. Molecular phylogenetic analyses confirm that both genera grouped as strongly supported distinct lineages out of the Amauroderma s.str. clade.
RESUMEN
OBJECTIVE: This study sought to evaluate the long-term osteosynthesis results for AO/OTA 31.A1-A2 pertrochanteric fractures treated with the percutaneous compression plate (PCCP). MATERIALS AND METHODS: This investigation was a retrospective observational descriptive study of 335 patients, with a minimum follow-up of 2 years and a maximum follow-up of 8 years (2004-2011). RESULTS: The average post-operative hospital stay was 6.2 days, and the average decrease in haemoglobin levels after the intervention was 2.7 mg/dL, with transfusion required for one-third of the patients. Complications related to the implant were observed in 4.2 % of patients; the most notable complication was cut-out (2.4 % of patients), and 3 cases involved pseudarthrosis with breakage of the implant (0.9 % of patients). CONCLUSIONS: From the results obtained in this study and an analysis of previously published work, we believe that the PCCP may be the implant of choice for AO/OTA 31.A1-A2 fractures.

UNLABELLED: Avian botulism kills thousands of waterbirds every year, including endangered species, but information about the differences between species in vulnerability to botulism outbreaks and the capacity to act as carriers of Clostridium botulinum is still poorly known. Here, we estimated the vulnerability to botulism of 11 waterbird species from Mediterranean wetlands by comparing the number of affected birds with the census of individuals at risk. The capacity of different species to act as carriers was studied by detecting the presence of the C. botulinum type C/D botulinum neurotoxin (BoNT) gene in fecal samples and prey items of waterbirds in the wild and by the serial sampling of cloacal swabs of birds affected by botulism. We found differences among species in their vulnerabilities to botulism, probably related to feeding habits, season of arrival, turnover, and, possibly, phylogenetic resilience. The globally endangered white-headed duck (Oxyura leucocephala) showed mortality rates in the studied outbreaks of 7% and 17% of the maximum census, which highlights botulism as a risk factor for the conservation of the species. Invasive water snails, such as Physa acuta, may be important drivers in botulism epidemiology, because 30% of samples tested positive for the BoNT gene during outbreaks. Finally, our results show that birds may excrete the pathogen for up to 7 days, and some individuals can do it for longer periods. Rails and ducks excreted C. botulinum more often and for longer times than gulls, which could be related to their digestive physiology (i.e., cecum development). IMPORTANCE: Botulism is an important cause of mortality in waterbirds, including some endangered species. The global climate change may have consequences in the ecology of wetlands that favor the occurrence of botulism outbreaks. Here, we offer some information to understand the ecology of this disease that can be useful to cope with these global changes in the future. We have found that some species (i.e., coots and dabbling ducks) are more vulnerable to botulism and have a more relevant role in the onset and amplification of the outbreaks than other species (i.e., flamingos and grebes). Feeding habits can explain these differences in part; in addition to the well-known role of necrophagous fly maggots, we found here that water snails are frequent carriers of Clostridium botulinum This is relevant, because these water snails can thrive in eutrophic and polluted wetlands, exacerbating other changes driven by climate change in wetlands.

Human gliomas are malignant brain tumours that carry a poor prognosis and are composed of a heterogeneous population of cells. There is a paucity of animal models available for study of these tumours and most have been created by genetic modification. Spontaneously arising canine gliomas may provide a model for the characterization of the human tumours. The present study shows that canine gliomas form a range of immunohistochemical patterns that are similar to those described for human gliomas. The in-vitro sphere assay was used to analyze the expansion and differentiation potential of glioma cells taken from the periphery and centre of canine tumours. Samples from the subventricular zone (SVZ) and contralateral parenchyma were used as positive and negative controls, respectively. The expansion potential for all of these samples was low and cells from only three cultures were expanded for six passages. These three cultures were derived from high-grade gliomas and the cells had been cryopreserved. Most of the cells obtained from the centre of the tumours formed spheres and were expanded, in contrast to samples taken from the periphery of the tumours. Spheres were also formed and expanded from two areas of apparently unaffected brain parenchyma. The neurogenic SVZ contralateral samples also contained progenitor proliferating cells, since all of them were expanded for three to five passages. Differentiation analysis showed that all cultured spheres were multipotential and able to differentiate towards both neurons and glial cells. Spontaneously arising canine gliomas might therefore constitute an animal model for further characterization of these tumours.

O exercício físico é um dos estímulos fisiológicos mais estressantes que um animal pode sofrer e, dependendo de sua intensidade, sugere-se que possa gerar uma reação mediada por proteínas de fase aguda (PFA). O objetivo deste estudo foi caracterizar a reação de fase aguda e sua relação com o desempenho de cavalos submetidos a uma competição de longa distância. O experimento foi desenvolvido durante a Marcha de Resistência anual promovida pela Associação Brasileira de Criadores de Cavalos Crioulos (ABCCC), composta por um percurso de 750km percorrido durante 15 dias. Foram avaliados 23 equinos, os quais foram divididos em dois grupos, sendo o grupo 1 composto pelos 10 primeiros colocados na competição e o grupo 2 formado pelos 13 animais que concluíram a competição em colocações inferiores ou foram desclassificados antes de terminar a prova. Efetuaram-se coletas sanguíneas em repouso (dia 0) e no último dia de competição, e foi realizado o teste de eletroforese em gel de poliacrilamida contendo dodecil sulfato de sódio (SDS-PAGE) para identificar as proteínas (albumina, haptoglobina, ceruloplasmina, transferrina, imunoglobulina G, imunoglobulina A, glicoproteína ácida e proteína de peso molecular de 23kDa). Os resultados demonstraram que o exercício físico imposto influenciou de forma significativa (P<0,0001) as concentrações séricas de haptoglobina, ceruloplasmina, imunoglobulina A, glicoproteína ácida e proteína de peso molecular de 23kDa. Quando comparados os resultados dos grupos estudados, observou-se que a concentração de haptoglobina após a competição foi superior no grupo de animais com baixo desempenho (grupo 2). Conclui-se que a competição de longa duração é capaz de gerar reação de fase aguda e que o monitoramento da concentração de haptoglobina pode ser um sinalizador de processo inflamatório e baixo desempenho.(AU)
Exercise is one of the most stressful physiologic stimuli that an animal might suffer, depending on its intensity it may generate a reaction mediated by acute phase proteins (APP). The aim of this study was to characterize the acute phase reaction and its relation to performance horses subjected to long distance competition. The experiment was conducted during the annual March of Resistance promoted by the Brazilian Association of Crioulo Horse Breeders (ABCCC), composed of a 750km route traveled during 15 days. 23 horses which were divided in two groups, one group composed by the 10 best placed horses and the second group consisting of 13 animals that have completed the competition in other positions or were disqualified before concluding the race were evaluated. All horses at the beginning of the competition (day 0) and on the last day of competition were subjected to collection of blood and SDS-polyacrylamide gel (SDS-PAGE) electrophoresis was used to measure APPs concentrations (albumin, ceruloplasmin, transferrin, haptoglobin, acid glycoprotein, immunoglobulin G, immunoglobulin A and a protein with molecular weight of 23 kDa). By the evaluation of the results, it was observed that exercise had a highly significant influence (P<0.0001) in the serum concentrations of the ceruloplasmin, haptoglobin, acid glycoprotein, immunoglobulin A and protein with molecular weight of 23kDa. When comparing the results of the study groups it was observed that the concentration of haptoglobin after the competition was higher in the group of animals with low performance (group 2). We conclude that the long term competition is able to generate acute phase reaction and monitoring the concentration of haptoglobin may be an indicator of inflammation and low performance.(AU)
