Intensity-modulated radiotherapy (IMRT) for cervical cancer yields favorable results in terms of oncological outcomes, acute toxicity, and late toxicity. Limited data are available on clinical results with volumetric modulated arc therapy (VMAT). This study's purpose is to compare outcome and toxicity with VMAT to conventional 3D conformal radiotherapy (3DCRT), giving special consideration to the influence of patient- and treatment-related parameters on side effects.

Patients with cervical cancer stageI-IVA underwent radiotherapy alone or chemoradiotherapy using 3DCRT (n = 75) or VMAT (n = 30). Survival endpoints were overall survival, progression-free survival, and locoregional control. The National Cancer Institute Common Terminology Criteria for Adverse Events and the Late Effects of Normal Tissues criteria were used for toxicity assessment. Toxicity and patient- and treatment-related parameters were included in amultivariable model.

There were no differences in survival rates between treatment groupher analysis of patient- and treatment-related parameters indicates that the close monitoring of patients with low BMI and of patients who experienced relevant acute toxicity during follow-up care could improve late toxicity profiles.

There are currently no data from randomized controlled trials on the use of intraoperative radiotherapy (IORT) as atumor bed boost as part of abreast-conservation approach for breast cancer. This study retrospectively reviewed the safety and efficacy of IORT as aboost treatment at atertiary cancer center.

From 2015 to 2019, patients underwent breast-conserving surgery with axillary lymph node staging and asingle dose of 20 Gy IORT with 50-kV photons, followed by whole-breast irradiation (WBI) and adjuvant systemic therapy (if applicable). Patients were followed for assessment of acute and late toxicities (using the Common Terminology Criteria for Adverse Events version 5.0) at 3-6-month intervals. Outcomes included ipsilateral (IBTR) and contralateral breast progression-free survival (CBE), distant metastasis-free survival (DMFS), and overall survival (OS).

Median follow-up for the 214patients was 28 (range 2-59) months. Most patients had T1 disease (n = 124) and were clinically node negative. Only few g results should be prospectively validated by the eventual publication of randomized studies such as TARGIT‑B.

This investigation provides additional preliminary data supporting the using of IORT in the boost setting and corroborates the existing literature. These encouraging results should be prospectively validated by the eventual publication of randomized studies such as TARGIT‑B.Aristolochic acid (AA-I) induces upper urothelial tract cancer (UUTC) and bladder cancer (BC) in humans. AA-I forms the 7-(2'-deoxyadenosin-N6-yl)aristolactam I (dA-AL-I) adduct, which induces multiple AT-to-TA transversion mutations in TP53 of AA-I exposed UTUC patients. This mutation is rarely reported in TP53 of other transitional cell carcinomas and thus recognized as an AA-I mutational signature. AT-to-TA transversion mutations were recently detected in bladder tumors of patients in Asia with known AA-I-exposure, implying that AA-I contributes to BC. Mechanistic studies on AA-I genotoxicity have not been reported in human bladder. In this study, we examined AA-I DNA adduct formation and mechanisms of toxicity in the human RT4 bladder cell line. The biological potencies of AA-I were compared to 4-aminobiphenyl, a recognized human bladder carcinogen, and several structurally related carcinogenic heterocyclic aromatic amines (HAA), which are present in urine of smokers and omnivores. AA-I (0.05-10 µM) induced a concentration- and time-dependent cytotoxicity. AA-I (100 nM) DNA adduct formation occurred at over a thousand higher levels than the principal DNA adducts formed with 4-ABP or HAAs (1 µM). dA-AL-I adduct formation was detected down to a 1 nM concentration. Studies with selective chemical inhibitors provided evidence that NQO1 is the major enzyme involved in AA-I bio-activation in RT4 cells, whereas CYP1A1, another enzyme implicated in AA-I toxicity, had a lesser role in bio-activation or detoxification of AA-I. AA-I DNA damage also induced genotoxic stress leading to p53-dependent apoptosis. These biochemical data support the human mutation data and a role for AA-I in BC.

Coital incontinence (CI) is an underreported symptom among sexually active women. It has been assumed that incontinence at penetration (CIAP) is due to urodynamic stress incontinence (USI), while coital incontinence at orgasm (CIAO) is thought to be due to detrusor overactivity (DO).

To evaluate demographic and urodynamic findings associated with coital incontinence (CI) and to confirm the hypotheses 'CIAP is associated with USI' and 'CIAO is associated with DO we performed a retrospective study of 661 sexually active women attending a tertiary clinic between January 2017 and December 2019 for pelvic floor dysfunction. All patients filled in a standardized questionnaire and had a clinical examination and multichannel urodynamic testing. Women were asked if they experienced urine leakage during intercourse and the timing of such leakage.

Of 661 sexually active women, one third (n = 220) reported coital incontinence. While 121 (18%) women experienced CIAP, 172 (26%) had CIAO and 76 (11.5%) suffered both. For women with pure USI, the prevalence of CIAP (61.7%) and CIAO (69.5%) was significantly higher than for women with pure DO, where only 12.3% had CIAP and 8.6% had CIAO. Factors significantly associated with CI were body mass index, mid-urethral closure pressure (MUCP) and abdominal leak point pressure (ALPP). When only women with pure USI or DO were included, USI remained associated with CI while DO was not.

CI is clearly associated with SUI and USI and is likely to share etio-pathogenetic mechanisms. CI seems to be a manifestation of USI, even when it occurs during orgasm.

To study the prevalence of pelvic floor dysfunction and related bother in primiparous women 6-10weeks postpartum, comparing vaginal and cesarean delivery.

Cross-sectional study of 721 mothers with singleton births in Reykjavik, Iceland, 2015 to 2017, using an electronic questionnaire. Information on urinary and anal incontinence, pelvic organ prolapse and sexual dysfunction with related bother (trouble, nuisance, worry, annoyance) was collected. Main outcome measures were prevalence of pelvic floor dysfunction and related bother.

The overall prevalence of urinary and anal incontinence was 48% and 60%, respectively. Bother regarding urinary symptoms was experienced by 27% and for anal symptoms by 56%. Pelvic organ prolapse was noted by 29%, with less than half finding this bothersome. Fifty-five percent were sexually active, of whom 66% reported coital pain. Of all the women, 48% considered sexual issues bothersome. Urinary incontinence and pelvic organ prolapse were more prevalent in women who delivered vaginally compared to cesarean section, but no differences were observed for anal incontinence and coital pain. Compared to women with BMI < 25, obesity was a predictor for urinary incontinence after vaginal delivery (OR 1.94; 95% CI 1.20-3.14). Birthweight > 50th percentile was predictive for urgency incontinence after vaginal delivery (OR 1.53; 95% CI 1.05-2.21). Episiotomy predicted more anal incontinence (OR 2.19; 95% CI 1.30-3.67). No associations between maternal and delivery characteristics were found for pelvic floor dysfunction after cesarean section.

This editorial is aimed at increasing awareness of mental issues amongst healthcare professionals, identifying perceived barriers to seeking help, and suggesting ways in which to seek help. Mental health disorders, including anxiety and depression, are prevalent from medical school, leading to increased burnout and suicide risks at later stages of a clinician's career. There is often a reluctance to seek help, particularly amongst the surgical specialties, caused by self-criticism, lack of convenient access and the potential negative impact on medical licensure. This editorial has been written in loving memory of our colleague, friend and board member Dr. FK506 solubility dmso Nikolaus Veit-Rubin, who sadly passed away at the beginning of the year. It is written in the hope of highlighting the importance of maintaining mental wellbeing amongst the medical team, supporting help-seeking behaviour and changing attitudes toward mental health disorders amongst clinicians.

We hypothesized obesity increases the risk of pelvic organ prolapse recurrence (POP-R) after primary apical prolapse repair.

We conducted a retrospective cohort study of 353 women who underwent primary apical prolapse surgery from 2011 to 2016. Demographic and clinical data were abstracted from medical records. Multivariable Cox proportional hazard models were used to generate hazard ratios (HR) for association between obesity (BMI ≥ 30kg/m

) and POP-R (leading edge > 0), adjusting for potential confounders. Given the potential for outcome ascertainment bias due to differential loss to follow-up, a sensitivity analysis was performed assuming all patients with < 6 months of follow-up developed POP-R.

Ten percent of women developed POP-R. The median follow-up time was 7 months (range 1.4, 63.9). Twenty-four percent of patients were Black and 70% were White; 37% were obese. After controlling for confounders, obese women did not have an increased risk of POP-R (aHR 1.39; 95% CI 0.67, 2.86, p = 0.38). Although only marginally statistically significant, patients who developed POP-R were more likely to be current smokers (aHR 3.48, 95% CI 1.14, 10.67; p = 0.06) or previous smokers (aHR 1.86, 95% CI 0.82, 4.24, p = 0.06) in comparison to non-smokers. Sensitivity analysis showed loss to follow-up had the potential to influence our results.

Obesity was not a risk factor for POP-R in our cohort. Larger, prospective studies with longer postoperative follow-up time are needed to fully elucidate the relationship between obesity and POP-R.

Since the publication of the large randomized controlled thrombectomy trials, endovascular treatment (EVT) has become the standard of care for acute stroke patients with anterior circulation large vessel occlusion (acLVO); however, the treatment of patients with an intracranial occlusion in the posterior circulation and in particular of the basilar artery has not been proven. Thus, there is uncertainty regarding the indications for EVT due to the poor evidence situation.

This review article addresses the current data on EVT in the posterior circulation and the most recent study results. Furthermore, the pathophysiological aspects, indications and specific features in the treatment of these patients are also discussed.

Despite limited evidence for EVT, this treatment modality has gained significant clinical relevance for the treatment of stroke patients with vascular occlusions in the posterior circulation. From atechnical point of view, vascular occlusions in the posterior circulation and particularly of the basilar artery are easily accessible, although the etiology of occlusions and necessary techniques differ compared to occlusions in the anterior circulation.
