Background While sex- or gender-based differences in pain expression have been documented, exploration of traditionally genderized traits on pain has been hampered by the lack of strong measurement tools. This study evaluated the structural validity of a 16-item "Gender personality traits" subscale of a recently developed Gender, Pain and Expectations Scale (GPES). Methods Data were drawn from an existing database of 248 participants (65.7% female). Maximum likelihood-based confirmatory factor analysis was carried out while considering the conceptual meaningfulness of subscales to evaluate the factor structure identified by these traits. Construct validity was explored using a priori hypotheses regarding anticipated mean differences in scores between biological male and female participants. Results A meaningful factor structure could not be defined with all 16 items. Through conceptual and statistical triangulation a three-factor structure informed by 10 items was identified that satisfied acceptable fit criteria. The factors were termed "Emotive," "Relationship-Oriented," and "Goal-Oriented." Evidence of construct validity was supported through significant sex-based differences (p ≤ 0.02) in the expected directions for all three subscales. Conclusions Review of the items in the three factors led the researchers to endorse a move away from naming these "masculine" and "feminine," rather focusing on the nature of the traits "Relationship-oriented," "Emotive," and "Goal-oriented." Implications for researchers conducting sex/gender-based pain research are discussed. Clinical Trial Registration number NCT02711085.Background The objective of the study was to compare family planning and infertility among female and male gynecologic oncologists in the United States Methods This cross-sectional multiple choice survey was administered to the Society of Gynecologic Oncology gynecologic oncologists. The survey collected information on demographics and practice, family planning, and fertility and infertility experiences. Chi-square and Fisher's exact tests were used to compare experiences by gender. Results Two hundred eighteen of 1243 (18%) members responded to the survey. The majority were women (71%), Caucasian (78%), and had been practicing fewer than 10 years (56%). One-third (32%) were 35+ years of age at the birth of their first child, and 67% delayed childbearing due to their career. Women were more likely than men to report career choice-influenced family planning. Just under half (44%) expressed current or past concerns about fertility, and this was more prevalent among women; 81% had sought infertility counseling. Among respondents who had fertility struggles, almost half (45%) reported their colleagues were unaware. Forty percent felt their fertility concerns affected work life, and 13% felt stigmatized for their fertility struggles. Conclusions These findings suggest that a career in gynecologic oncology have an impact on family planning, often resulting in childbearing delays and infertility concerns, especially among women. Support for our colleagues struggling with infertility should be included in wellness initiatives.Cortical synchronization in the gamma-frequency range (above ~30.0 Hz) and the signal/noise interplay described by stochastic resonance models have been proposed as basic mechanisms in neuronal synchronization and sensory information processing, particularly in vision. Here we report an observation in humans of linear and inverted-U distributions of the electrophysiological (EEG) responses to visual contrast stimulation in the gamma band and in the low frequency components of the visual evoked responses (VER), respectively. The combination of linear and inverted-U distributions is described by a stochastic resonance model (SR). The observation needs replication in larger subjects' samples. It nevertheless adds to the available evidence of a role of gamma oscillatory signals and SR mechanisms in neuronal synchronization and visual processing. Some functional adaptation in human vision appears conceivable and further investigation is warranted.<br />Intravascular lobular capillary haemangioma is a rare benign intravascular tumour, especially in large vessels. This is the report of a case and associated literature review.<br />This is the report of the first case of an intravenous lobular capillary haemangioma (ILCH) of the superior vena cava (SVC). A 30 year old female presented with a collateral thoraco-abdominal venous circulation. Chest computed tomography angiography, thoracic magnetic resonance imaging, and positron emission tomography revealed an intraluminal SVC tumour extending from the left brachiocephalic venous trunk to the distal third of the SVC. No pre-operative biopsy was indicated. An<br />tumour excision was performed, followed by reconstruction of the SVC with an L shaped, ringed polytetrafluoroethylene (PTFE) prosthesis. Histopathology revealed the presence of an ILCH with free margins. A review of the literature identified 64 cases of ILCH to date, all of which underwent total resection. When reported, no recurrences were found during follow up.<br />In this case, the ePTFE reconstruction of the SVC must be checked regularly for any adverse events. Although ILCH is a benign tumour with no risk of recurrence, regular surveillance is advised.<br />In this case, the ePTFE reconstruction of the SVC must be checked regularly for any adverse events. Although ILCH is a benign tumour with no risk of recurrence, regular surveillance is advised.<br />Pullthrough/body floss wires are used to track endovascular devices across tortuous aorto-iliac anatomy encountered during endovascular repair of abdominal or thoracic aortic aneurysms. The tension imparted on such wires is arbitrary and has never been quantified. [https://www.selleckchem.com/products/vacuolin-1.html Vacuolin-1 cell line] This pilot study attempted to quantify the tension used to stiffen the floppy hydrophilic wires typically used in such a scenario.<br />Two linked experiments were undertaken, the first by tasking 13 blinded vascular surgeons (eight male, five female; mean age 36 ± 11 years, including nine trainees) with pulling a long floppy hydrophilic wire (Radifocus Guidewire M Stiff, Terumo UK, Bagshot, Surrey, UK) attached at the other end to a horizontally configured industrial scale (HDN-N Hanging Scale, Kern &amp; Sohn GmbH, Balingen, Germany), to simulate what they individually felt was an "appropriate" tension; the second by using the derived average tensioning force to set up a pullthrough wire within a rigid life like aorto-iliac model to assess whether a test device (16F Sentrant Introducer Sheath, Medtronic Limited, Watford, UK) could be delivered over such a tensioned wire in both brachiofemoral and femorofemoral configurations.
