Outcome of treatment with a 10-week COP protocol in cats with intermediate or large cell lymphoma: 27 cases (2014-2023).

OBJECTIVES: The aim of this retrospective clinical study was to evaluate and report response to treatment with a 10-week maintenance-free COP (COP-10) protocol in a cohort of 27 cats with intermediate or large cell lymphoma. Additionally, to identify any potential prognostic factors for predicting the treatment response. MATERIALS AND METHODS: The medical records of cats diagnosed with intermediate or large cell lymphoma in a single institution in the period 2014 to 2023 and treated with COP-10 as first-line treatment were reviewed. RESULTS: Twenty-seven cats were included in the study. The median age was 10 years, 67% of the cats were in stages I to II and the most common anatomical location was alimentary (37%). The overall response rate was 65%, with 38% of cats achieving complete remission and 27% partial remission. For cats achieving complete remission, the median progression-free interval and the median lymphoma-specific survival time were both 1,139 days. For cats in partial remission, the median progression-free interval and the median lymphoma-specific survival time were 53 and 210 days, respectively. Clinical stage was significantly related to treatment response and survival time. CLINICAL SIGNIFICANCE: Treatment with the short protocol COP-10 resulted in remission rates and durable first remissions for cats achieving complete remission comparable to responses seen with longer-duration chemotherapy protocols. The results from this study may impact economic and logistic decisions for owners, as well as the quality of life for patients in the future.

Phenotype analysis of families with TP53 germline variants at the Center for Familial Breast and Ovarian Cancer, Cologne.

PURPOSE: Tumor protein p53 (TP53) pathogenic variant (PV) carriers are identified during genetic testing for hereditary causes of cancer. PVs in TP53 are associated with the Li-Fraumeni syndrome (LFS), and thus, surveillance and preventive measures are important for TP53 PV carriers. However, the penetrance of TP53 PVs can be low if the Chompret criteria are not fulfilled. In this study, we compared the phenotypic characteristics of families that did and did not fulfill the LFS criteria according to Chompret. METHODS: The German Consortium for Hereditary Breast and Ovarian Cancer (GC-HBOC) database was used to identify index patients with a likely pathogenic/pathogenic TP53 variant and their family members. The study investigated the type of variant, pedigree, age of onset, number of primary tumors, and histological type of BC. RESULTS: TP53 PV were present in the index cases of 35 families, 57% (20/35) of which fulfilled the Chompret criteria. The median age of onset at first BC diagnosis was lower in families that fulfilled the Chompret criteria compared to those who did not. Four of all diseased individuals were minors (4%; 4/105) when malignancy was first diagnosed. Sarcomas and brain tumors occurred in 10% (10/105) and in 7% (7/105) of all diseased persons, respectively. BC was the most frequently occurring first tumor (60%; 62/105) and additional malignancy (45%; 20/44) in this cohort. Subsequent malignancies developed in 31% (20/65) of the individuals who fulfilled the Chompret criteria compared with 15% (6/40) of those who did not. CONCLUSION: The tumor spectrum and age of onset found in this study showed that tumors other than BC had low disease penetrance in TP53 PV carriers identified using the GC-HBOC criteria for genetic testing.

Standardised or individualised X-ray tube angle for mediolateral oblique projection in digital mammography?

INTRODUCTION: We aimed to investigate whether there were any differences in positioning criteria related to the presentation of the pectoralis major muscle (pectoral muscle) for women of different heights using a standardized 60° X-ray tube angle for mammograms in mediolateral oblique (MLO) projection. METHODS: Data from MLO mammograms of right breasts of 45,193 women screened in BreastScreen Norway 2016-2019 were used. The positioning criteria were related to the pectoral muscle length (measure A and measure B), width and shape and considered adequate or inadequate depending on the degree of fulfilling the criteria. Data associated with the pectoral muscle were extracted from Volpara, an automated software for breast density assessment. Information on height was obtained from a self-reported questionnaire received by the women together with the invitation to attend the screening program. Women were divided into three groups based on the height percentiles (P) in the Norwegian growth curves: < 25th percentile (75th percentile (>P75th: >170 cm). Logistic regression was used to analyse the odds of adequate pectoral muscle length A and B, and shape, adjusting each model for screening technique and equipment model. Results were presented with odds ratios (OR) and 95% confidence intervals (CI). RESULTS: Mean age of the screened women was 61.5 (SD = 4.8) years. The adequate measure for the pectoral muscle length A was obtained for 25.9% (11,724/45,193), length B for 76.3% (34,489/45,193), width for 75.0% (33,894/45,193) and shape for 97.6% (44,118/45,193) of the mammograms. Adjusted odds of an adequate pectoral muscle length A were lower for women of P75th (OR = 1.08, 95% CI 1.02-1.14) compared to women of P25-75. Odds of an adequate pectoral muscle shape were higher for women of P75th (OR = 0.92, 95% CI 0.87-0.97) compared to women of P25-75th. CONCLUSION: The 60° X-ray tube angle might suit most of the female population offered mammographic screening in Norway, but women of a relatively low height (163 cm or lower) might benefit from an X-ray tube angle less than 60-degrees. IMPLICATIONS FOR PRACTICE: Using 60° X-ray tube angle for the MLO mammograms in BreastScreen Norway fit the majority of the participating women. More research is needed to change the protocol associated with the tube angle for women shorter than 163 cm.

The use of advanced platelet-rich fibrin after surgical removal of mandibular third molars: a systematic review and meta-analysis.

The objective of this systematic review was to test the hypothesis of no difference in recovery following surgical removal of mandibular third molars with the application of advanced platelet-rich fibrin (A-PRF) in the extraction socket compared with alternative biomaterials or natural wound healing. A search of MEDLINE (PubMed), Embase, Cochrane Library, and Scopus was conducted. Human randomized controlled trials published in English up until December 31, 2020 were included. Outcome measures were pain, facial swelling, trismus, soft tissue healing, alveolar osteitis, and quality of life; these were evaluated by descriptive statistics and meta-analysis including 95% confidence intervals (CI). Four studies with a low or moderate risk of bias fulfilled the inclusion criteria. A-PRF resulted in significantly lower pain scores when compared with leucocyte platelet-rich fibrin or natural wound healing after 2 days (-16.8, 95% CI -18.9 to -14.7), 3 days (-12.1, 95% CI -13.4 to -10.7), and 7 days (-1.9, 95% CI -2.9 to -0.9). A-PRF seems to have a negligible effect on facial swelling and trismus and some beneficial effect on soft tissue healing. Alveolar osteitis and quality of life were not assessed. The included studies were characterized by considerable heterogeneity and confounding variables. Thus, the level of evidence appears to be inadequate for clinical recommendations according to the focused question.

Clinically decisive (dis)agreement in multidisciplinary team assessment of esophageal squamous cell carcinoma; a prospective, national, multicenter study.

BACKGROUND: Decisions regarding tumor staging, operability, resectability, and treatment strategy in patients with esophageal cancer are made at multidisciplinary team (MDT) conferences. We aimed to assess interobserver agreement from four national MDT conferences and whether this would have a clinical impact. METHODS: A total of 20 patients with esophageal cancer were included across all four upper gastrointestinal (GI) cancer centers. Fully anonymized patient data were distributed among the MDT conferences which decided on TNM category, resectability, operability, curability, and treatment strategy blinded to each other's decisions. The interobserver agreement was expressed as both the raw observer agreement and with Krippendorff's α values. Finally, a case-by-case evaluation was performed to determine if disagreement would have had a clinical impact. RESULTS: A total of 80 MDT evaluations were available for analysis. A moderate to near-perfect observer agreement of 79.2%, 55.8%, and 82.5% for TNM category was observed, respectively. Substantial agreement for resectability and moderate agreement for curability were found. However, an only fair agreement was observed for the operability category. The treatment strategies had a slight agreement which corresponded to disagreement having a clinical impact in 12 patients. CONCLUSIONS: Esophageal cancer MDT conferences had an acceptable interobserver agreement on resectability and TM categories; however, the operability assessment had a high level of disagreement. Consequently, the agreement on treatment strategy was reduced with a potential clinical impact. In future MDT conferences, emphasis should be on prioritizing the relevant information being readily available (operability, T & M categories) to minimize the risk of disagreement in the assessments and treatment strategies, and thus, delayed or suboptimal treatment.

Danish translation and validation of the Self-reported foot and ankle score (SEFAS) in patients with ankle related fractures.

BACKGROUND: The Self-reported Foot and Ankle Score (SEFAS) is a patient-reported outcome measure used to evaluate foot and ankle disorders. The purpose of this study was to translate, cross-culturally adapt and validate the Danish language version of the SEFAS in patients with ankle-related fractures. METHODS: Forward-backward translation, cross-cultural adaption and validation were performed. In total, 125 patients completed the SEFAS-DK and the Danish version of American Orthopaedic Foot and Ankle Score (AOFAS-DK) at three time points after the date of fracture. The evaluation was performed according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines. RESULTS: The intra-class correlation coefficient (ICC) level of the SEFAS-DK total score was 0.93 (95% confidence interval [CI]: 0.88-0.96). Cronbach's alpha (CA) for the SEFAS-DK was 0.93, while the floor and ceiling effect at week 6 post-injury was 22.4%. Construct validity was correlated with the AOFAS, and >75% of the pre-defined hypotheses could be confirmed. Responsiveness was analysed using longitudinal data. The minimal clinical important change (MCIC) showed that the SEFAS-DK detects changes in physical function over time. CONCLUSION: The Danish version of the SEFAS showed overall good reliability, validity and responsiveness. SEFAS-DK can be used to evaluate physical function in patients with ankle-related fractures. LEVEL OF EVIDENCE: level II, prospective cohort study.

Efficacy of methylprednisolone on pain, trismus and quality of life following surgical removal of mandibular third molars: a double-blind, split-mouth, randomised controlled trial.

BACKGROUND: The objective of the present study was to compare the efficacy of different doses of methylprednisolone on postoperative sequelae and quality of life (QoL) following surgical removal of mandibular third molars (SRM3). MATERIAL AND METHODS: Fifty-two patients (16 men and 36 women, mean age 25.9 years, range: 18-39) with bilateral impacted mandibular third molars were randomly allocated into intraoperative muscular injection of either 20mg, 30mg, 40mg methylprednisolone or saline injection. Baseline measurements were obtained preoperatively and compared with assessment after one day, three days, seven days and one month. Pain and trismus were estimated by visual analog scale score and interincisal mouth opening, respectively. Subjective assessment of QoL included Oral Health Impact Profile (OHIP-14). Descriptive and generalized estimating equation analyses were made and expressed as mean values with a 95% confidence interval. RESULTS: Methylprednisolone revealed no significant differences in pain, trismus and QoL compared with placebo. Higher prevalence of postoperative pain and worsening in QoL were observed with increased age (P=0.00). Smoking and increased time of surgery decreased mouth opening in the early healing phase (P=0.00). CONCLUSIONS: The present study revealed no significant improvement of methylprednisolone on postoperative sequelae and QoL following SRM3 compared with placebo.

Colon capsule endoscopy versus CT colonography after incomplete colonoscopy. Application of artificial intelligence algorithms to identify complete colonic investigations.

BACKGROUND: Guidelines suggest computed tomography colonography (CTC) following incomplete optical colonoscopy (OC). Colon capsule endoscopies (CCE) have been suggested as an alternative, although completion rates have been unsatisfactory. Introduction of artificial intelligence (AI)-based localization algorithms of the camera capsules may enable identification of incomplete CCE investigations overlapping with incomplete OCs. OBJECTIVE: The study aims to investigate relative sensitivity of CCE compared with CTC following incomplete OC, investigate the completion rate when combining results from the incomplete OC and CCE, and develop a forward-tracking algorithm ensuring a safe completeness of combined investigations. METHODS: In this prospective paired study, patients with indication for CTC following incomplete OC were included for CCE and CTC. Location of CCE abortion and OC abortion were registered to identify complete combined investigations. AI-based algorithm for localization of capsules were developed reconstructing the passage of the colon. RESULTS: In 237 individuals with CTC indication; 105 were included, of which 97 underwent both a CCE and CTC. CCE was complete in 66 (68%). Including CCEs which reached most oral point of incomplete OC, 73 (75%) had complete colonic investigations; 78 (80%) had conclusive investigations. Relative sensitivity of CCE compared with CTC was 2.67 (95% confidence interval (CI) 1.76;4.04) for polyps >5 mm and 1.91 (95% CI 1.18;3.09) for polyps >9 mm. An AI-based algorithm was developed. CONCLUSION: Sensitivity of CCE following incomplete OC was superior to CTC. Introducing and improving algorithm-based localization of capsule abortion may increase identification of overall complete investigation rates following incomplete OC.ClinicalTrials.gov identifier: NCT02826993.

Low attendance by non-native women to human papillomavirus vaccination and cervical cancer screening - A Danish nationwide register-based cohort study.

BACKGROUND: Cervical cancer is preventable through human papillomavirus vaccination and cervical cancer screening. However, possibly due to systemic, individual (e.g. low socio-economic staus) and socio-cultural barriers, it is likely that non-natives, especially non-westerns, are more prone to attend neither vaccination nor screening (combined non-attendance). This is disturbing as the non-native population in Denmark is predicted to rise to 21% by 2060. We aimed to investigate differences in combined non-attendance by nativity and region of origin, and to analyse the association between country of origin and combined non-attendance adjusted for socio-economic status. SETTING: 1.6.2007-31.12.2016 Denmark. METHODS: Logistic regression was performed to estimate crude and adjusted odds ratios with 95% confidence intervals for combined non-attendance. RESULTS: 170,158 women were included. Overall combined non-attendance was 11.8% [11.7-12.0]; 10.0% [9.8-10.1] for native women and 27.1% [26.4-27.7] for non-native women, with highest degrees among Middle-Eastern and North-Africans (30.1% [29.2-30.9]). Even when adjusted for socio-economics, women from Middle-East and North-Africa had substantially higher odds of combined non-attendance than natives (adj. OR = 7.5 [6.3-8.9] for Somali women). CONCLUSION: Denmark has a relatively low degree of combined non-attendance. However, cervical cancer preventive programmes seem to be better tailored to the needs of native women and do not appear to cater sufficiently to the needs of the fast-growing non-native populations, particularly not to the needs of Middle-Eastern and North African women. In order to secure more just cervical cancer prevention, future studies are recommended to develop tailored intervention sensitive to the need of non-native women.

Validity and reliability of State-Trait Anxiety Inventory in Danish women aged 45 years and older with abnormal cervical screening results.

BACKGROUND: State Trait Anxiety Inventory (STAI) scale was developed in the 1980's and has been widely used both in clinical settings and in research. However the Danish version of STAI has not been validated. The aim of this study was to assess the validity and reliability of STAI - state anxiety scale in Danish women aged 45 years and older with abnormal cervical cancer screening results. METHODS: Women ≥45 years referred with an abnormal cervical cytology and healthy volunteers (n = 12) underwent cognitive interview after completing STAI. Further, STAI was sent out in an electronic questionnaire to women (n = 109) seen at the gynecological department with abnormal cervical cancer screening test during 2018. Validity and reliability of STAI was evaluated according to the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) checklist by examining internal consistency, test-retest reliability, measurement error, floor and ceiling, construct validity and content validity. RESULTS: In the cognitive interviews the content validity was evaluated to be very good. The internal consistency of the scale was excellent with Cronbach's α = 0.93. Test-retest reliability was good with an intra-class correlation coefficient of 0.80 and the systematic difference between test-retest results was negligible. The construct validity was good. CONCLUSION: To our best knowledge, this is the first validation study of the Danish translation of STAI-state anxiety scale. This version of STAI demonstrates an acceptable reliability and validity when used in a gynecological setting.

Regional Differences following Partial Salivary Gland Resection.

Regenerative medicine aims to repair, replace, or restore function to tissues damaged by aging, disease, or injury. Partial organ resection is not only a common clinical approach in cancer therapy but also an experimental injury model used to examine mechanisms of regeneration and repair in organs. We performed a partial resection, or partial sialoadenectomy, in the female murine submandibular salivary gland (SMG) to establish a model for investigation of repair mechanisms in salivary glands (SGs). After partial sialoadenectomy, we performed whole-gland measurements over a period of 56 d and found that the gland increased slightly in size. We used microarray analysis and immunohistochemistry (IHC) to examine messenger RNA and protein changes in glands over time. Microarray analysis identified dynamic changes in the transcriptome 3 d after injury that were largely resolved by day 14. At the 3-d time point, we detected gene signatures for cell cycle regulation, inflammatory/repair response, and extracellular matrix (ECM) remodeling in the partially resected glands. Using quantitative IHC, we identified a transient proliferative response throughout the gland. Both secretory epithelial and stromal cells expressed Ki67 that was detectable at day 3 and largely resolved by day 14. IHC also revealed that while most of the gland underwent a wound-healing response that resolved by day 14, a small region of the gland showed an aberrant sustained fibrotic response characterized by increased levels of ECM deposition, sustained Ki67 levels in stromal cells, and a persistent M2 macrophage response through day 56. The partial submandibular salivary gland resection model provides an opportunity to examine a normal healing response and an aberrant fibrotic response within the same gland to uncover mechanisms that prevent wound healing and regeneration in mammals. Understanding regional differences in the wound-healing responses may ultimately affect regenerative therapies for patients.

The role of home visits by a nurse to improve palliation in patients treated with self-expandable metallic stents due to incurable esophageal cancer.

Self-expandable metallic stent (SEMS) is a preferred option to relieve dysphagia and to palliate patients with incurable esophageal or gastro-esophageal junction (GEJ) cancer. Health Related Quality of Life (QoL) represents a clinically relevant outcome measure in research focused on palliation of patients with advanced GI cancer. In this context, home visits by a nurse carry the potential to offer important advantages. Eighty patients with incurable esophageal or GEJ cancer were randomized to either standard follow up or to an intervention containing regular home visits by a nurse. The primary outcome variable QoL was assessed by EORTC QLQ-C30 and OES-18 before insertion of SEMS, and at 2, 7 and 12 weeks thereafter. Secondary outcomes were; need for re-interventions, number of patients receiving palliative oncological therapy and overall survival. Sixty-six males and 13 females, with a median age of 71, were included. Self-reported overall QoL was significantly higher in the intervention group (P = 0.03). The organ specific module OES-18 revealed a significant reduction in dysphagia by the intervention (P = 0.03) as well as fewer eating disabilities (P = 0.04). No differences were observed in secondary outcomes except for overall survival, where the median survival was increased from 114 to 183 days by the active intervention (P = 0.02). Home visits by a nurse seem to play an important palliative role after placement of SEMS in patients with incurable esophageal or GEJ cancer by improving QoL and may carry the potential to increase overall survival.

Simultaneous vs staged bilateral total knee arthroplasty: a propensity-matched case-control study from nine fast-track centres.

INTRODUCTION: Limited data exist on patient safety after simultaneous vs staged bilateral total knee arthroplasty (TKA) in matched groups. Hence, the aim of this study was to compare length of stay (LOS), in-hospital complications, 30-day readmissions and mortality after simultaneous and staged bilateral TKA in matched patients. PATIENTS AND METHODS: A retrospective case-control study of prospectively collected data in nine centres from February 2010 to November 2015. Propensity scores (PS) were used to match simultaneous and staged (1-6 months between stages) bilateral TKA patients with prospectively collected patient characteristics from the Lundbeck Foundation Centre for Fast-track THA and TKA Database. 30-day follow-up was acquired from the Danish Patient Registry and patient records. RESULTS: A total of 344 (47.1%) simultaneous and 386 (52.9%) staged bilateral TKA procedures were performed. PS matching was possible in 232 simultaneous and 232 staged bilateral TKA patients. LOS was median 4 days (IQR 3-5) after simultaneous and cumulated 4 days (IQR 4-6) after staged procedures. The in-hospital complication rate was 15.5% after simultaneous vs 7.3% (p = 0.004) after staged procedures. Two cases (0.9%) of venous thromboembolic events were found in each group. Eight patients (3.4%) were re-operated after simultaneous vs one patient (0.4%) after staged bilateral TKA (p = 0.037). The 30-day readmission rate was 8.6% after simultaneous vs 5.6% after staged procedures (p = 0.281). No patients died in either group. CONCLUSIONS: We found no significant differences in 30-day readmission rates and mortality between simultaneous and staged bilateral TKA, but the in-hospital complication rate and re-operation rate was higher after the simultaneous procedure calling for further matched investigations in larger cohorts.

Liquid Nitrogen Spray Cryotherapy in Treatment of Barrett's Esophagus, where do we stand? A Systematic Review and Meta-Analysis.

Radiofrequency ablation (RFA) is the preferred treatment option for Barrett's esophagus (BE) to achieve complete eradication (CE) of dysplasia (D), and intestinal metaplasia (IM). Cryotherapy, using liquid nitrogen (LNC), is a cold-induced tissue-injury technique option for the ablation of BE. We conducted a systematic review and meta-analysis to assess the overall efficacy and safety of LNC in the treatment of BE. We conducted a search of multiple electronic databases and conference proceedings from inception through June 2018. The primary outcome was to estimate the pooled rates of CE-IM, CE-D, and CE-HGD. The secondary outcome was to estimate the risk of adverse events and recurrence of disease after LNC. Nine studies reported 386 patients who were treated with LNC. The pooled rate of CE-IM was 56.5% (95% CI 48.5-64.2, I2 = 47), pooled rate of CE-D was 83.5% (95% CI 78.3-87.7, I2 = 22.8), and pooled rate of CE-HGD was 86.5% (95% CI 64.4-95.8, I2 = 88.1). Rate of adverse events was 4.7%, and the risk of BE recurrence was 12.7%. On subgroup analysis, the pooled rate of CE-IM with LNC in patients who failed RFA was 58.4% (95% CI 47.2-68.8, I2 = 32.5), and the pooled rate of CE-D in the same population was 81.9% (95% CI 72.5-88.6, I2 = 5.9). CE-D rates with LNC are comparable to RFA while CE-IM rates appear to be lower than the rates achievable with RFA. CE-IM rate in RFA failed patients is 58.4% and thus LNC is a rescue option to consider in this population.

Colon capsule endoscopy for colonic surveillance.

AIM: Resources used in surveillance colonoscopies are taking up an increasing proportion of colonoscopy capacity. Colon capsule endoscopy (CCE) is a promising technique for noninvasive investigation of the colon. We aimed to investigate CCE as a possible filter in colonic surveillance with the primary outcome of reducing the number of colonoscopies. METHOD: Patients scheduled for follow-up colonoscopy were subjected to a primary CCE and only supplemental conventional endoscopy if significant pathology was detected or if the CCE examination was incomplete. Significant pathology was defined as more than two small polyps, or one polyp greater than 9 mm or any polyp in patients with hereditary nonpolyposis colorectal cancer. Supplemental endoscopy was carried out to the extent needed to resect the detected polyps and investigate the parts of the colon that were not sufficiently visualized by the capsule. RESULTS: A total of 180 patients were included. Seventy-seven patients (43%) had a complete CCE with no significant findings. A complete colonoscopy was carried out in 67 patients (37%) and 36 patients (20%) underwent a sigmoidoscopy. In the 103 patients undergoing endoscopy, 59 (57%) had no adenomas detected, 33 (32%) had 'low-risk' adenomas and 11 (11%) had 'high-risk' adenomas. CONCLUSION: The introduction of CCE as filter test in colonic surveillance reduced colonoscopies by 43%, but this implies that untreated polyps are left behind and is not cost-effective. The CCE completion rate must be improved.

Evaluation of tumor-infiltrating lymphocytes and association with prognosis in BRCA-mutated breast cancer.

BACKGROUND: Patients with a BRCA1 or BRCA2 mutation (BRCA-mutated breast cancer) are frequently diagnosed with low differentiated and highly proliferating breast cancer characterized by high amounts of tumor-infiltrating lymphocytes (Tils). Stromal Tils (sTils) are highly prognostic in sporadic triple-negative and HER2 positive breast cancer however, their prognostic importance in BRCA-mutated breast cancers is unknown. MATERIAL AND METHODS: Formalin-fixed paraffin-embedded primary tumor tissue from 411 patients with a germline BRCA1 or BRCA2 mutation and diagnosed with early breast cancer was included. The percentage of sTils was quantified on full HE sections according to guidelines proposed by the Immuno-Oncology Biomarker in Breast Cancer Working Group. Distribution of sTils and associates with patient and tumor characteristics were assessed according to categorical sTils groups defined as low (<10%), intermediate (10-59%) and high (≥60%). Prognostic associations of sTils were evaluated as a continuous variable in univariate and multivariate models. Only follow-up time beyond date of BRCA mutation test was included. RESULTS: A large proportion had high sTils (27% in the full cohort, 36% in BRCA1-mutated, and 44% in ER negative breast cancers). Higher sTils were associated with BRCA1, ER negative breast cancer, high histological grade and medullary histology. In combined analysis for BRCA1 and BRCA2-mutated breast cancers, increasing sTils in 10% intervals were significantly associated with OS (HR 0.92, 95% CI 0.84-1.00, p = .05). For each 10% increment of sTils in BRCA1 breast cancers, a 10% reduction of mortality (adjusted HR 0.90 95% CI 0.81-0.99, p = .03) and a 13% reduction in risk of DFS-event (HR 0.87 95% CI 0.76-1.00, p = .05) was observed even after adjustment for ER status. No significant association with survival was of observed in the BRCA2 subgroup. Test for interaction of sTils and BRCA status was not statistically significant (p = .3). CONCLUSIONS: Breast cancer patients with a germline BRCA mutation had higher sTils than previously reported in sporadic breast cancers, and sTils were associated with favorable survival among BRCA carriers.

Significance of progesterone receptors (PR-A and PR-B) expression as predictors for relapse after successful therapy of endometrial hyperplasia: a retrospective cohort study.

OBJECTIVE: After successful progestin therapy for endometrial hyperplasia (EH), the risk of relapse remains. We aimed to assess if immunohistochemical (IHC) expression of progesterone receptor isoforms, PR-A and PR-B, in endometrial glands and stroma in pre-treatment endometrial biopsies was related to relapse of EH. DESIGN AND SETTING: Biopsy material originated from women with low-risk and medium-risk EH recruited to a recent Norwegian multicentre randomised trial. Participants (n = 153) had been treated for 6 months with three different progestin regimens. POPULATION: One hundred and thirty-five of the 153 women achieved therapy response and underwent follow up for 24 months after therapy withdrawal. Fifty-five women relapsed during follow up. Pre-treatment endometrial biopsies from 94 of the 135 responding women were available for IHC staining. METHODS: Immunohistochemical staining was performed separately for PR-A and PR-B and IHC expression was evaluated in endometrial glands and stroma by a histological score (H-score) using light microscopy. MAIN OUTCOME MEASURE: Immunohistochemical expression of PR-A and PR-B in endometrial glands and stroma in women with or without relapse of EH. RESULTS: Low PR-A in endometrial glands (P = 0.013) and stroma (P < 0.001), and high PR-B in endometrial glands (P = 0.001) in pre-treatment endometrial biopsy have a statistically significant association with relapse of EH. Women with a pre-treatment ratio of PR-A:PR-B ≤ 1 have a higher risk of relapse (71%) compared with women with a ratio of PR-A:PR-B > 1 (19%; P < 0.001). CONCLUSION: Immunohistochemical expression of PR-A and PR-B in pre-treatment endometrial biopsy proves valuable as a predictor of relapse in EH. TWEETABLE ABSTRACT: Pre-treatment endometrial expression of PR-A and PR-B is a valuable predictor of relapse in endometrial hyperplasia.

Increased Use of Medications for Erectile Dysfunction in Men With Ulcerative Colitis and Crohn's Disease Compared to Men Without Inflammatory Bowel Disease: A Nationwide Cohort Study.

BACKGROUND: Men with inflammatory bowel disease (IBD) may have decreased sexual function due to factors related to the underlying disease, medication, and/or surgery. We aimed to examine the use of erectile dysfunction (ED) medications in men with IBD. METHODS: This is a nationwide cohort study based on the Danish registries, comprising all men >18 years old with IBD during 1 January 1995 through December 2016. The cohorts included 31,498 men with IBD and 314,980 age-matched men without IBD. Our main outcome was a first prescription of an ED medication. Cox regression analyses were used to estimate the hazard rate (HR) for use of ED medications, controlled for multiple time-varying covariates. RESULTS: Overall, 21,966 (69.7%) men had ulcerative colitis (UC) while 9532 (30.3%) had Crohn's disease (CD). Men with a first ED prescription numbered 3749 (11.9%) (men with IBD) and 30,635 (9.7%) (men without IBD). Adjusting for central nervous system and intestinal anti-inflammatory medications, systemic corticosteroids and co-morbidities, the HR was 1.19 (95% CI: 1.13-1.26) (IBD and no prior IBD operation), and 1.31 (95% CI: 1.20-1.43) (IBD and prior IBD operation). The adjusted HR for UC was 1.17 (95% CI: 1.10-1.24) (no operation) and 1.43 (95% CI: 1.27-1.61) (prior operation), and for CD 1.26 (95% CI: 1.15-1.38) (no operation) and 1.20 (95% CI: 1.06-1.35) (prior operation). DISCUSSION: Men with IBD are more likely to fill an ED prescription than men without IBD. This result is significant regardless of a history of IBD surgery.

Evaluation of strategies for the treatment of type B and C pelvic fractures: results from the German Pelvic Injury Register.

Aims: The best method of treating unstable pelvic fractures that involve the obturator ring is still a matter for debate. This study compared three methods of treatment: nonoperative, isolated posterior fixation and combined anteroposterior stabilization. Patients and Methods: The study used data from the German Pelvic Trauma Registry and compared patients undergoing conservative management (n = 2394), surgical treatment (n = 1345) and transpubic surgery, including posterior stabilization (n = 730) with isolated posterior osteosynthesis (n = 405) in non-complex Type B and C fractures that only involved the obturator ring anteriorly. Calculated odds ratios were adjusted for potential confounders. Outcome criteria were intraoperative and general short-term complications, the incidence of nerve injuries, and mortality. Results: Operative stabilization reduced mortality by 36% (odds ratio (OR) 0.64, 95% confidence interval (CI) 0.42 to 0.98) but the incidence of complications was twice as high (OR 2.04, 95% CI 1.57 to 2.64). Mortality and the incidence of neurological deficits at discharge were no different after isolated posterior or combined anteroposterior fixation. However, the odds of both surgical (98%, OR 1.98, 95%CI 1.22 to 3.22) and general complications (43%, OR 1.43, 95% CI 1.02 to 2.00) were higher in the group with the more extensive surgery. Conclusion: Operative stabilization is recommended for non-complex unstable pelvic fractures. The need for anterior fixation of obturator ring fractures should, however, be considered critically.
