RESUMEN

OBJECTIVE: This study aims to summarize the evidence concerning the barriers that exist to the career progression of women in surgery and to provide potential solutions to overcome these obstacles. BACKGROUND: Visible and invisible impediments can hinder female doctors' pursuit of a surgical career, from choosing a surgical specialty to training opportunities and all the way through career progression. METHODS: Database search of original studies about barriers for female surgeons during choice of surgical career, residency, and career progression. A query including possible solutions such as mentorship and network was included. RESULTS: Of 4618 total articles; 4497 were excluded as duplicates, having incorrect study focus, or not being original studies; leaving 120 studies meeting the inclusion criteria. Of the articles included, 22 (18%) focused on factors affecting the pursuit of a surgical career, such as surgical work hours and limited time for outside interests, 55 (46%) analyzed the main barriers that exist during surgical residency and fellowship training, such as discrimination and sexual harassment, 27 (23%) focused on barriers to career advancement, heavy workloads, ineffective mentorship, unclear expectations for advancement, inequality in pay or work-home conflicts. Among studies reporting on possible solutions, 8 (6.5%) articles reported on the role of effective mentorship to support career advancement and to provide moral support and 8 (6.5%) on the emerging role of social media for networking. Our analysis showed how different impediments hinder surgical career progression for women, with notable consequences on burnout and attrition. CONCLUSIONS: Identification and recognition of obstacles to career progression is the first step to addressing the gender gap in surgery. Active strategies should be improved to promote a culture of diversity and to create equal opportunity for women in surgery, while implementing structured mentoring programs and investing on an adequate communication on social media to engage the future generations.

RESUMEN

BACKGROUND: Over the past twenty years explicit gender bias toward women in surgery has been replaced by more subtle barriers, which represent indirect forms of discrimination and prevents equality. OBJECTIVE: The aim of our scoping review is to summarize the different forms of discrimination toward women in surgery. METHODS: The database search consisted of original studies regarding discrimination toward female surgeons. RESULTS: Of 3615 studies meeting research criteria, 63 were included. Of these articles, 11 (18%) were focused on gender-based discrimination, 14 (22%) on discrimination in authorship, research productivity, and research funding, 21 (33%) on discrimination in academic surgery, 7 (11%) on discrimination in surgical leadership positions and 10 (16%) on discrimination during conferences and in surgical societies. The majority (n = 53, 84%) of the included studies were conducted in the U.S.A. According to our analysis, female surgeons experience discrimination from male colleagues, healthcare workers, but also from patients and trainees. Possible solutions may include acknowledgment of the problem, increased education of diversity and integration for the younger generations, mentorship, coaching, and more active engagement by male and female partners to support women in the surgical field. CONCLUSIONS: Gender-based discrimination toward women in the field of surgery has evolved over the past twenty years, from an explicit to a more subtle attitude. A work-environment where diversity and flexibility are valued would allow female surgeons to better realize their full potential.

RESUMEN

BACKGROUND: Sporadic women involvement in surgery has been recorded since ancient times. Nevertheless, the presence of women in surgical disciplines has been marginal until the last 2 decades, with several barriers still existing worldwide. The aim of the study was to explore the history of women in surgery, with a main focus in North America from until the foundation women surgical societies. METHODS: Database search of studies about the history of women in surgery. RESULTS: The 19th century registered an increased presence of women in medicine; during the 20th century, pioneer women surgeons opened the way to a more consistent involvement of women in surgical specialties. In the last 20 years, increased awareness of barriers limiting women progression in surgical career led to the development of women's surgical societies, with the aim to share common experiences and find solutions to common issues. CONCLUSION: The history of women in surgery has been paved with challenges: during the last centuries, several barriers limited the inclusion of women in surgical fields, from training to leadership positions. Nevertheless, some pioneers actually broke the rules imposed by a male-dominated field and opened the way to a more diverse and equal future for women surgeons. Nowadays, the existence of women's surgical societies in different countries and their interconnection represents a way to support women surgeons at different stages of their career.

RESUMEN

OBJECTIVE: Wound healing in venous leg ulcer (VLU) is a multi-step process involving complex pathways. Scanty knowledge at molecular level hinders clinical assessment and treatment. Anomalous handling of local iron overload, as well as unbalancing in matrix metalloproteinases (MMPs) and transglutaminase, has a recognized role in VLU establishment. We selected a number of single nucleotide polymorphisms (SNPs) in candidate genes (HFE, FPN1, MMP12, and FXIII) involved in VLU to identify potentially prognostic markers by means of DNA-array technology. METHODS AND RESULTS: The DNA-array-genotyping was assessed in 638 subjects for the following SNPs: HFE (C282Y, H63D), FPN1 (-8CG), MMP12 (-82AG) and FXIII (V34L). Of the subjects, 221 were affected by VLU (171 primary and 50 post-thrombosis), 112 by severe chronic venous disease (CVD) (CEAP, C3-C4), while 305 were matched healthy controls. The HFE and FXIII SNPs had been previously genotyped by conventional polymerase chain reaction (PCR)-methods on the same group of subjects (J Vasc Surg 2005;42:309; J Vasc Surg 2006;44:554; J Vasc Surg 2006;44:815). For the purpose of DNA-array, they were re-genotyped by means of array-techniques resulting in a 100% matching. Intergroup statistical comparisons were performed. In the risk computation, the FPN1 -8GG genotype had an overall CVD risk of 4.3 (95% CI, 1.6-12) and a VLU risk of 5.2 (95% CI, 1.9-15) virtually the same among primary VLU (4.98; 95% CI, 1.82-14.9). The MMP12-82AA genotype had a VLU risk of 1.96 (95% CI, 1.18-3.2) only in primary VLU (P = .01). In the genotype-ulcer size association studies, from a subgroup of 167 cases, we observed a smaller mean ulcer size in the MMP12 GG-genotype compared with the other genotypes (P = .001). Combining the present results with our previous published data on the same population, we suggest them to apply as tentative prognostic indicators in primary CVD. CONCLUSION: By analyzing simultaneously selected SNPs, it might be possible to glean precious information in predicting VLU onset or in stratifying patients according to their potential to heal. Although significant, our findings must be considered preliminary and the proposed prognostic indicators considered with caution, before ulterior more extensive studies in different populations can eventually confirm the present findings.

RESUMEN

In multiple sclerosis (MS) plaques are known to be venocentric; in addition, MS lesions and peripheral venous disorders share a number of key features. To date, however, despite the anatomical relationship between MS lesions and the venous system, no information on the intracranial venous haemodynamics of MS is available. Eighty-nine consecutive MS patients (58 relapsing-remitting, 31 secondary progressive) matched with 60 controls underwent transcranial color-coded duplex sonography (TCCS). We assessed, in supine as well as in sitting positions, the direction of flow at the activation of the thoracic pump in the deep middle cerebral veins (dMCVs), and in the transverse sinus (TS). In the dMCVs, we also measured peak systolic velocity (PSV), peak diastolic velocity (PDV), as well as the resistance index (RI). Reflux/bidirectional flow rate was significantly higher in the MS population determining also significant differences in PDV, characterized by negative values (16.2+/-1 cm/sec in controls vs. -1.3 +/-2.6 cm/sec in MS, respectively, p<0.0001). Consequently, RI was dramatically increased in the MS group, affecting impedance of cerebral venous drainage (0.48+/-0.04 in controls vs. 1.1 +/-0.08 in MS, respectively p<0.0001). Therefore, the detection of reflux directed toward the subcortical grey matter was significantly associated to highest disability scores (p < 0.0001). Our study of MS patients demonstrated significant haemodynamic alterations detected in veins anatomically related to plaque disposition. Our findings should contribute towards understanding the role of altered venous flow and tissue drainage in the MS inflammatory chain, as well as in the neurodegenerative process.

RESUMEN

Iron stores in the white and deep grey matter in course of multiple sclerosis (MS) have never been explained and could be related to abnormalities in venous drainage, but this possibility has never before been investigated. From an initial cohort of 320 subjects, after application of exclusion criteria, we selected 109 patients affected by MS, and 177 controls respectively composed by age- and sex-matched, healthy aged, and patients affected by other neurological diseases. They blindly underwent transcranial and extracranial Color-Doppler sonographic examination (TCCS-ECD), aimed at investigating five parameters related to normal cerebral venous outflow haemodynamics. Overall we analyzed 1430 TCSS-ECD parameters. In controls we found 861 normal parameters of cerebral venous return vs. 24 anomalous, whereas in MS 288 parameters were normal and 257 anomalous, respectively. Consequently, each of the considered Doppler haemodynamic parameters, when compared to revised McDonald criteria as a gold standard of MS diagnosis, showed separately a highly significant sensitivity and a noteworthy specificity. However, the detection >or=2 parameters in the same subject, never observed in controls, perfectly overlapped the diagnosis of MS (value, 95%CI: sensitivity 100%, 97-100; specificity 100%, 98-100; positive predictive value 100%, 97-100, negative predictive value 100%, 98-100; p<0.0001). Moreover, this study demonstrates a significant impairment of cerebral venous drainage in patients affected by MS, a mechanism potentially related to increased iron stores.

RESUMEN

A new nosologic vascular pattern that is defined by chronic cerebrospinal venous insufficiency (CCSVI) has been strongly associated with multiple sclerosis. The picture is characterized by significant obstacles of the main extracranial cerebrospinal veins, the jugular and the azygous system, and by the opening of substitute circles. The significance of collateral circle is still neglected. To the contrary, substitute circles are alternative pathways or vicarious venous shunts, which permit the drainage and prevent intracranial hypertension. In accordance with the pattern of obstruction, even the intracranial and the intrarachidian veins can also become substitute circles; they permit redirection of the deviated flow, piping the blood toward available venous segments outside the central nervous system. We review the complex gross and radiological anatomy of collateral circulation found activated by the means of EchoColor-Doppler and selective venography in the event of CCSVI, focusing particularly on the suboccipital cavernous sinus (SCS), the condylar venous system, the pterygoid plexus, the thyroid veins, and the emiazygous-lumbar venous anastomosis with the left renal vein.

RESUMEN

OBJECTIVE: Many factors impair healing of chronic venous ulcer (CVU), and many theories have been proposed to explain their pathogenesis. Coagulation factor XIII (FXIII) influences tissue regeneration and angiogenesis with effects on wound healing. Because FXIII properties depend upon its genetic variants, we investigated whether intragene polymorphisms may have modulating effects on the CVU area. METHODS: The study included 121 patients with nonhealing CVUs (CEAP clinical class C6) that included 67% with primary chronic venous disease (CVD), 26% with post-thrombotic ulcers, and 7% with mixed ulcer origin. Polymerase chain reaction was used to genotype them for Val34Leu, Pro564Leu, and Tyr204Phe variants in the FXIII-A subunit gene and for His95Arg variant in the FXIII-B subunit gene. The same variants were analyzed in 102 controls, healthy subjects who were case-matched by age and gender. RESULTS: Genotype distribution for all polymorphisms investigated was not significantly different between cases and controls. Conversely, our CVU cases had a mean ulcer area inversely related with the presence of both Leu34 and Leu564 alleles (ValVal, 12.3 +/- 22.4 cm2 vs LeuLeu, 3.9 +/- 2.6 cm2, P = .002; ProPro, 10.2 +/- 21.2 cm2 vs LeuLeu, 2.9 +/- 1.4 cm2, P = .002). In combined analysis, those cases who were wild-type for both variants (ValVal34/ProPro564) had a further increase in mean ulcer size compared with cases carrying both variants (Leu34/Leu564) (13.3 +/- 27.1 cm2 vs 5.2 +/- 5.6 cm2; P = .034). CONCLUSIONS: No correlation exists between FXIII genotypes and the prevalence of chronic venous ulcers, thus demonstrating that FXIII polymorphisms have no role in ulcer development. In contrast, FXIII-gene variants, in particular the non-wild-type alleles Leu34 and Leu564, were associated with a smaller venous ulcer surface and might have favorable effects on reparative processes.
