Gender diversity in health teams is associated with better productivity. As women's participation in surgery has been growing, it is important to improve knowledge about the elements that guide their professional development.
The aim of this study was to outline the demographic and professional features of female vascular surgeons in Brazil.
A cross-sectional study was designed, in which a questionnaire was made available online for 60 days. Invitations to participate were distributed by institutional e-mail sent from the Brazilian Society of Angiology and Vascular Surgery (SBACV) to associate women surgeons. Results are presented as numbers and percentages. Odds ratios and chi-square tests were used for analysis.
From a total of 810 invitations sent out, 281 questionnaires were completed. The most prevalent age groups were 25-35 years (n = 115) and 36-45 years (n = 114). Among those who worked exclusively in the private sector, 79.8% had at least one board certification (OR 0.76, 95% CI 0.65-0.89; p = 0.001). Regarding workload distribution, 64.4% and 34.2% reported that they spend more time in the clinic and hospital, respectively. Respondents with more years of experience reported a predominance of office practice (p = 0.002). Although 67.3% (n = 189) had published scientific papers, 68% (n = 191) had never held leadership roles.
The study respondents consisted of highly qualified women surgeons with respect to training, certification, and scientific engagement, but they remain underrepresented in professional management positions. Surgical societies and health institutions should act to promote inclusive and diverse leadership.

Chronic venous insufficiency (CVI) is a common disease that causes calf muscle pump dysfunction and has repercussions for the hemodynamics of the structures involved.
To analyze the effects on venous hemodynamics of exercises to strengthen the calf muscles in patients with CVI.
The study analyzed 25 lower limbs with CVI, classified from C1 to C5 according to the Clinical, Etiology, Anatomy, and Pathophysiology (CEAP) classification, in 13 patients recruited from a Lymphedema and Angiodysplasia Clinic at the Hospital Universitário Regional dos Campos Gerais (Brazil). The variables analyzed were collected by isometric dynamometry, goniometry, leg circumference measurement, and adipometry at baseline, after 1 month and 2 months and at the end of the exercise protocol.
Dorsiflexion and plantar flexion measurements increased by 5º (p < 0.001). Adipometry detected a reduction in 5 mm (p < 0.001). When grouped by CEAP class, C2 exhibited 5º increases in dorsiflexion (p = 0.02) and plantar flexion (p < 0.001); C3 exhibited a 5ºincrease in dorsiflexion (p = 0.003) and a 1mm reduction in adipometry (p < 0.004); and C1 exhibited a 1.2cm increase in leg circumference (p = 0.04).
Administration of exercise protocols should be considered as a treatment option for CVI, since it has a positive impact on risk factors and on the functions that are impaired by this pathology.

Tenascin-C is a glycoprotein that can be found in situations involving tissue damage. The objective of this article is to evaluate whether Tenascin-C assays could be of use for predicting prognosis in abdominal aortic aneurysms and acute aortic dissection. We conducted an integrative literature review, for which four articles were considered eligible. Two of these studies associated higher Tenascin-C levels with protective factors and lower risk of injury, whereas the other two correlated them with worse prognosis. Some authors believe that Tenascin-C could be a candidate biomarker, but these studies are still inconclusive with regard to its role in the clinical outcomes of patients with aneurysms.We report a case of an asymptomatic, 77-year-old, male patient with arterial hypertension and no other comorbidities or risk factors for coronary disease. During a routine abdominal ultrasound examination, he was diagnosed with a hepatic vascular mass with an approximate diameter of 5 cm. Abdominal computed angiotomography was requested, showing an aneurysm of the hepatic artery, with maximum diameter of up to 5.2 cm, longest longitudinal axis of 7.2 cm, and a maximum true lumen caliber of 3.0 cm. We opted for endovascular aneurysm repair with implantation of three sequential Lifestream covered vascular stents (7x58mm, 8x58mm, and 8x37mm), successfully diverting the flow through the stents and excluding the aneurysm. The patient remains asymptomatic and free from clinical complications 2 years after the procedure. Control examinations with arterial duplex ultrasound 6 and 12 months after the procedure showed good flow through the stents with no leakage into the aneurysmal sac.Soil salinization is one of the major abiotic stresses that adversely affect the yield and quality of crops such as wheat, a leading cereal crop worldwide. Excavating the salt-tolerant genes and exploring the salt tolerance mechanism can help breeding salt-tolerant wheat varieties. Thus, it is essential to identify salt-tolerant wheat germplasm resources. In this study, we carried out a salt stress experiment using Qing Mai 6 (QM6), a salt-tolerant wheat variety, and sequenced the miRNAs and mRNAs. The differentially expressed miRNAs and mRNAs in salt stress conditions were compared with the control. As results, a total of eight salt-tolerance-related miRNAs and their corresponding 11 target mRNAs were identified. Further analysis revealed that QM6 enhances salt tolerance through increasing the expression level of genes related to stress resistance, antioxidation, nutrient absorption, and lipid metabolism balance, and the expression of these genes was regulated by the identified miRNAs. The resulting data provides a theoretical basis for future research studies on miRNAs and novel genes related to salt tolerance in wheat in order to develop genetically improved salt-tolerant wheat varieties.Gene expression was analyzed at 0- and 24-h post-inoculation of two inbred sorghum cultivars known to differ in response to inoculation with Colletotrichum sublineola, the fungal pathogen that causes anthracnose. QL3 is reported to have quantitative resistance, while Theis is susceptible to most pathotypes of the pathogen; RNASeq identified over 3,000 specific genes in both cultivars as showing significant changes in expression following inoculation; in all but one gene, the changes in QL3 and Thies were in the same direction. Many other genes showed significant changes in only one of the two cultivars. Overall, more genes were downregulated than upregulated. Differences in changes in expression levels of a few genes suggested potential roles for the difference in disease response between QL3 and Theis, but did not identify known resistance genes. Gene ontology (GO) and pathway enrichment analysis identified upregulation of 23 transcription factor encoding genes as well as genes involved in the production of secondary metabolites, which are part of a typical host defense reaction.X-linked hypohidrotic ectodermal dysplasia with the cardinal symptoms hypodontia, hypotrichosis and hypohidrosis is caused by a genetic deficiency of ectodysplasin A1 (EDA1). Prenatal EDA1 replacement can rescue the development of skin appendages and teeth. Tabby mice, a natural animal model of EDA1 deficiency, additionally feature a striking kink of the tail, the cause of which has remained unclear. We studied the origin of this phenomenon and its response to prenatal therapy. Alterations in the distal spine could be noticed soon after birth, and kinks were present in all Tabby mice by the age of 4 months. Although their vertebral bones frequently had a disorganized epiphyseal zone possibly predisposing to fractures, cortical bone density was only reduced in vertebrae of older Tabby mice and even increased in their tibiae. Different availability of osteoclasts in the spine, which may affect bone density, was ruled out by osteoclast staining. The absence of hair follicles, a well-known niche of epidermal stem cells, and much lower bromodeoxyuridine uptake in the tail skin of 9-day-old Tabby mice rather suggest the kink being due to a skin proliferation defect that prevents the skin from growing as fast as the skeleton, so that caudal vertebrae may be squeezed and bent by a lack of skin. Early postnatal treatment with EDA1 leading to delayed hair follicle formation attenuated the kink, but did not prevent it. Tabby mice born after prenatal administration of EDA1, however, showed normal tail skin proliferation, no signs of kinking and, interestingly, a normalized vertebral bone density. Thus, our data prove the causal relationship between EDA1 deficiency and kinky tails and indicate that hair follicles are required for murine tail skin to grow fast enough. Disturbed bone development appears to be partially pre-determined in utero and can be counteracted by timely EDA1 replacement, pointing to a role of EDA1 also in osteogenesis.Short stature is a frequent disorder in the pediatric population and can be caused by multiple factors. In the last few years, the introduction of Next Generation Sequencing (NGS) in the molecular diagnostic workflow led to the discovery of mutations in novel genes causing short stature including heterozygous mutations in ACAN gene. It encodes for aggrecan, a primary proteoglycan component specific for the structure of the cartilage growth plate, articular and intervertebral disc. We report a novel ACAN heterozygous pathogenic variant in a family with idiopathic short stature, early-onset osteoarthritis and osteoarthritis dissecans (SSOAOD). We also performed a literature review summarizing the clinical characteristic of ACAN's patients. find more The probands are two Caucasian sisters with a family history of short stature and osteoarthritis dissecans. They showed dysmorphic features such as mild midface hypoplasia, brachydactyly and broad thumbs, especially the great toes. The same phenotype was presented in the mother who had had short stature and suffered from intervertebral disc disease. DNA sequencing identified a heterozygous pathogenic variation (c.4390delG p.Val1464Ter) in the sisters, with a maternal inheritance. The nonsense mutation, located on exon 12, results in premature truncation and presumed loss of protein function. In terms of treatment, our patients underwent recombinant human growth hormone replacement therapy, associated with gonadotropin releasing hormone therapy, in order to block early growth cessation and therefore reach a better final height. Our case suggests that SSOAOD ACAN related should be considered in the differential diagnosis of children with autosomal dominant short stature and family history of joints disease.
