Narrowing women's time and income gaps: An assessment of the synergies between working time reduction and universal income schemes

This paper departs from the hypothesis that policies targeting time poverty have the potential to reduce the gender income gap through the redistribution of time use between women and men. To this purpose, we compare two policy mixes and assess the synergies between working time reduction and two universal income schemes: a basic income and care income programme. While the former provides every individual with an equal monetary benefit, the latter ties monetary benefits to the amount of unpaid and care work performed by individuals. We assess the impact of these policy mixes by applying Eurogreen, a macrosimulation model tailored to Italy. Results suggest that while working time reduction directly drives a reduction of the aggregate amount of time spent by women in unpaid work, this does not imply a reduction in time poverty. The universal income schemes – and in particular the care income – promote a reduction of gender inequality in terms of income by sustaining women's total income, but leave the wage gap between women and men unchanged

Growth of Focal Nodular Hyperplasia is Not a Reason for Surgical Intervention, but Patients Should be Referred to a Tertiary Referral Centre

Background: When a liver lesion diagnosed as focal nodular hyperplasia (FNH) increases in size, it may cause doubt about the initial diagnosis. In many cases, additional investigations will follow to exclude hepatocellular adenoma or malignancy. This retrospective cohort study addresses the implications of growth of FNH for clinical management. Methods: We included patients diagnosed with FNH based on ≥2 imaging modalities between 2002 and 2015. Characteristics

The role of MRI in perianal fistulizing disease:diagnostic imaging and classification systems to monitor disease activity

Perianal fistulizing disease, commonly associated with Crohn's disease, poses significant diagnostic and therapeutic challenges due to its complex anatomy and high recurrence rates. Radiological imaging plays a pivotal role in the accurate diagnosis, classification, and management of this condition. This article reviews the current radiological modalities employed in the evaluation of perianal fistulizing disease, including magnetic resonance imaging (MRI), endoanal ultrasound, and computed tomography (CT). MRI, recognized as the gold standard, offers superior soft tissue contrast and multiplanar capabilities, facilitating detailed assessment of fistula tracts and associated abscesses. CT, although less detailed than MRI, remains valuable in acute settings for detecting abscesses and guiding drainage procedures. This article discusses the advantages and limitations of each modality, highlights the importance of standardized imaging protocols, and underscores the need for interdisciplinary collaboration in the management of perianal fistulizing disease. Future directions include advancements in imaging techniques and the integration of artificial intelligence to enhance diagnostic accuracy and treatment outcomes

Accuracy of preoperative liver volumetry in living donor liver transplantation—A systematic review and meta-analysis

Background: Liver volume measurement plays a critical role in the clinical success of living donor liver transplantation (LDLT). CT liver volumetry is used for volumetric assessment of the donor hepatectomy. However, the degree of accuracy of the preoperative predicted volumetric measurements remains unclear. Purpose: This systematic review will assess the accuracy of CT liver volumetry. Materials and Methods: A systematic literature search was conducted to evaluate the accuracy of the CT based liver volumetry. To assess the difference between the left and right liver lobe the ratio between preoperative estimated graft volume (EGV) and actual graft weight (AGW) was calculated. A meta-analysis was performed to compare the EGV to the AGW of the left and right lobe with automated and manual CT volume prediction. Results: Thirty-one studies met the inclusion criteria and 1336 patients were included in the meta-analysis. The EGV of the right liver is overestimated with a mean of 4.01% and 2.99% for automated and manual volumetry respectively. The left lobe is overestimated with 6.28% and 14.41% for automated and manual volumetry respectively. For a right lobe liver graft automated volume prediction showed a mean difference of 43.9 g (95% confidence interval (CI): 21.21–66.54, p&lt;0.001) between EGV and AGW. For manual volume prediction this was 34.0 g (95% CI: 11.85–56.11, p = 0.003). For a left lobe with automated volume prediction the mean difference was 46.0 g (95% CI: 20.91–71.09, p&lt;0.001) between EGV and AGW. For manual volume prediction this was 39.6 g (95% CI: 8.40–70.74, p = 0.01). Conclusion: The volumes of the right and left liver lobe seem to be overestimated with automated and manual CT volume prediction. Considering the larger estimation error in the prediction of the left liver lobe, special attention should be paid to the volume when performing a LDLT with a left liver lobe to prevent small for size syndrome.</p

Additional Intraoperative Autologous-Derived Platelet-Rich Stroma to Transanal Flap Repair for the Treatment of Cryptoglandular Transsphincteric Fistulas in a Tertiary Referral Center:Long-Term Outcomes of a Prospective Pilot Study

Transanal advancement flap repair (TAFR) fails in approximately 30–40% of patients with a cryptoglandular transsphincteric fistula. An additional intraoperative injection of autologous platelet-rich stroma (PRS) with TAFR proved to be safe, feasible, and effective in the short term for the treatment of cryptoglandular transsphincteric fistula in a tertiary referral center. In this study, we assessed the long-term outcomes in patients with a cryptoglandular transsphincteric fistula who were treated with an additional intraoperative autologous PRS injection with TAFR (n = 43). The majority of the patients (88%) had a complex transsphincteric fistula (high transsphincteric and/or multiple side tracts) and underwent (one or more) fistula procedure(s) aimed at fistula repair (56%) before study inclusion. At a median follow-up time of 4.2 years [IQR 3.5–5.1], long-term primary clinical closure (i.e., clinical closure of the treated external fistula opening(s) after TAFR with additional PRS injection without the need for any re-interventions during long-term follow-up) was observed in 77% of the patients. Subsequently, 94% of these patients also reached radiological healing (i.e., fibrotic fistula tract on MRI). Recurrence after clinical closure or radiological healing was observed in 9% and 5%. Unplanned re-interventions were performed in 12% of the patients for recurrent or residual fistulizing disease. In this uncontrolled pilot study, additional autologous PRS injection with TAFR showed promising outcomes, as long-term primary clinical closure and, subsequently, radiological healing was reached in the vast majority of tertiary referral patients with a (complex) cryptoglandular transsphincteric fistula at long-term follow-up. In addition, recurrence rates were low. Future randomized research is warranted to study the effects of PRS.</p

Intraoperative Autologous Platelet-Rich Stroma Injection as Add-On to Fistula Curettage and Closure of the Internal Orifice Demonstrates a Favorable Outcome in Long-Term in Patients Suffering from Therapy-Refractory Perianal Fistulizing Crohn's Disease

Background:An injection with autologous platelet-rich stroma (PRS), a combination of stromal vascular fraction and platelet-rich plasma, as an add-on to fistula curretage and closure of the internal orifice proved to be safe and feasible for the treatment of patients with treatment-refractory perianal fistulizing Crohn's disease (pCD). This study aimed to assess the long-term outcomes in patients with pCD treated with autologous PRS injection. Methods:Adult patients with therapy-refractory pCD (failure to anti-tumor necrosis factor [TNF] therapy and/or fistula surgery), who underwent fistula curettage, closure of the internal fistula orifice, and autologous PRS injection in a Dutch tertiary referral center were included in an earlier conducted pilot study (n = 25). The primary outcome was complete clinical closure at long-term follow-up (closure of all treated external opening[s]). Secondary outcomes were partial clinical closure (closure of ≥1 treated external opening[s]), radiologic healing (fibrotic fistula tract on magnetic resonance imaging), and recurrence. Results:The majority of the patients were female (56%) (mean age 34.4 years [standard deviation - SD: 0.9], and mean follow-up 3.7 years [SD: 0.6]). The treatment-refractory character of the study cohort was displayed by the high rate of patients with ≥1 external opening (60%), prior exposure to an anti-TNF agent (92%), TOpClass classification system ≥ class 2b (36%), and the low rate of patients who underwent prior surgical interventions aimed at fistula closure (12%). During long-term follow-up, complete clinical closure was achieved in 88%. Partial clinical closure was achieved in all patients. Radiologic healing was achieved in 75% of the patients. Recurrence was reported in 8% of the patients who achieved prior clinical closure. No recurrences were observed in patients with radiologic healing. Seventeen unplanned re-interventions were reported in nine patients (36%), predominantly for residual fistulizing disease and in patients with severe therapy-refractory pCD (TOpClass classification system ≥ class 2b) at the time of inclusion. Conclusion:Additional PRS injection, fistula curettage, and closure of the internal orifice is a promising therapy for patients with (treatment-refractory) pCD and could improve clinical and radiologic healing rates. In addition, low recurrence rates were observed. Future randomized research is warranted in order to assess the effectiveness and positioning of PRS in the field of pCD.</p

Endoscopic ultrasound with tissue acquisition of lymph nodes in patients with potentially resectable intrahepatic cholangiocarcinoma

Background and study aims Lymph node (LN) involvement is a poor prognostic factor for patients with intrahepatic cholangiocarcinoma (iCCA). The aim of this study was to evaluate the yield and impact on clinical decision making of endoscopic ultrasound with tissue acquisition (EUS-TA) of LNs in patients with potentially resectable iCCA. Patients and methods In this multicenter cohort study, patients with potentially resectable iCCA and preoperative EUS between 2010 and 2020 were retrospectively included. The impact of EUS-TA was defined as the percentage of patients who did not undergo surgical exploration due to pathologically confirmed positive LNs found with EUS-TA. Results A total of 56 patients underwent EUS, with 91% of patients to target suspicious LNs on imaging. EUS-TA of LNs confirmed malignancy in 21 LNs among 19 patients (34%). In 17 patients (30%), surgical exploration was withheld due to nodal involvement. Finally, 24 patients (43%) underwent surgical exploration among whom positive regional LNs were identified in six patients (25%). Conclusions In patients with potentially resectable iCCA and suspicious LNs on cross-sectional imaging, EUS-TA confirmed LN involvement in 30% of patients. Surgical exploration was withheld mostly because of extraregional LN involvement and regional LN involvement in patients with high surgical risk. </p

¹⁸F-FDG PET/MRI for restaging esophageal cancer after neoadjuvant chemoradiotherapy

PURPOSE: The purpose of this study was to investigate whether 18F-fluorodeoxyglucose ( 18 F-FDG) PET/MRI may potentially improve tumor detection after neoadjuvant chemoradiotherapy (nCRT) for esophageal cancer. METHODS: This was a prospective, single-center feasibility study. At 6-12 weeks after nCRT, patients underwent standard 18 F-FDG PET/computed tomography (CT) followed by PET/MRI, and completed a questionnaire to evaluate burden. Two teams of readers either assessed the 18 F-FDG PET/CT or the 18 F-FDG PET/MRI first; the other scan was assessed 1 month later. Maximum standardized uptake value corrected for lean body mass (SUL max ) and mean apparent diffusion coefficient (ADC mean ) were measured at the primary tumor location. Histopathology of the surgical resection specimen served as the reference standard for diagnostic accuracy calculations. When patients had a clinically complete response and continued active surveillance, response evaluations until 9 months after nCRT served as a proxy for ypT and ypN (i.e. 'ycT' and 'ycN'). RESULTS: In the 21 included patients [median age 70 (IQR 62-75), 16 males], disease recurrence was found in the primary tumor in 14 (67%) patients (of whom one ypM+, detected on both scans) and in locoregional lymph nodes in six patients (29%). Accuracy (team 1/team 2) to detect yp/ycT+ with 18 F-FDG PET/MRI vs. 18 F-FDG PET/CT was 38/57% vs. 76/61%. For ypN+, accuracy was 63/53% vs. 63/42%, resp. Neither SUL max (both scans) nor ADC mean were discriminatory for yp/ycT+ . Fourteen of 21 (67%) patients were willing to undergo a similar 18 F-FDG PET/MRI examination in the future. CONCLUSION: 18 F-FDG PET/MRI currently performs comparably to 18 F-FDG PET/CT. Improvements in the scanning protocol, increasing reader experience and performing serial scans might contribute to enhancing the accuracy of tumor detection after nCRT using 18 F-FDG PET/MRI.
