In the human and equine species, different kinds of free floating intra-articular particles are related to certain disorders. Osteochondral fragments formed during osteochondrosis dissecans are the most common finding in the equine species, whereas in humans rice bodies due to rheumatoid arthritis are more frequent. Herein we report a third type of floating body inside the stifle of an adult draught horse stallion, in macroscopic appearance similar to articular rice bodies known in humans. As revealed by histologic examination, the two particles consist of polypoid degenerated structures derived from synovial villi. Their formation was probably induced by ischemia.

Purpose:
Neoadjuvant chemotherapy (NAC) involving trastuzumab markedly increases pathologic complete response (pCR) rates in patients with human epidermal growth factor receptor 2-positive (HER2+) breast cancer. Despite increasing pCR rates, long-term survival gains are controversial owing to distinctive biologic behavior mediated by the presence of hormonal receptors (HRs) that may interact with HER2 receptors. We, therefore, investigated the differences in relative survival gain provided by neoadjuvant trastuzumab-based chemotherapy on HR positive (HR+) status of patients.
Methods:
We retrospectively ana Patient clinical characteristics were compared usin lyzed women with stage II or III HER2+ breast cancer who underwent NAC followed by a breast cancer surgery between 2008 and 2013. The survival benefits of adding trastuzumab to NAC were analyzed by classifying patients into HR+ and HR negative (HR−) groups.
Results:
Of 666 patients included in the study, 374 (52.1%) were HR+ and 319 (47.9%) were HR−. In the HR+ group, trastuzumab treatment led to higher pCR rates and significantly better breast cancer specific survival (BCSS) and overall survival (OS) than no trastuzumab treatment. However, among patients with HR− breast cancer, trastuzumab treatment showed no statistically significant difference between BCSS and OS following multivariate analysis.
Conclusion
We found that the addition of trastuzumab to NAC improved relative survival benefit in HER2+/HR+ patients than in HER2+/HR− patients, even though the pCR rate increases were lower. Although pCR has been regarded as a surrogate marker for estimating long-term survival benefits after NAC, it alone may not translate into real long-term oncologic outcomes in particular cancer subtypes after trastuzumab-based NAC. Further longer-term evaluation of the objective survival benefit after NAC driven by a dual HER2 block according to HR status is warranted.

Robust data evaluating the association of preoperative parameters of the patients with quality of life after radical prostatectomy are lacking. We investigated whether clinical and biological preoperative characteristics of the patients were associated with impaired patient-reported quality of life (QoL) and sexual outcomes 1 year after radical prostatectomy. We evaluated patient-reported outcomes among the 1343 men participating in the AndroCan trial (NCT02235142). QoL and erectile dysfunction (ED) were assessed before and 1 year after radical prostatectomy using validated self-assessment questionnaires (Aging Male's Symptoms [AMS] and the 5-item abridged version of the International Index of Erectile Function [IIEF5]). At baseline, 1194 patients (88.9%) accepted to participate. A total of 750 (55.8%) patients answered the 1-year postoperative questionnaires. Out of them, only 378 (50.4% of responders) provided answers that could be used for calculations. One year after prostatectomy, ED had worsened by 8.0 (95% confidence interval [CI]: 7.3-8.7; P < 0.0001) out of a maximum of 20. The global AMS score has worsened by 2.8 (95% CI: 1.7-3.8; P < 0.0001). ED scores 1 year postsurgery were positively correlated with preoperative age and percentage of fat mass, and negatively correlated with total cholesterol, dehydroepiandrosterone (DHEA), and androstenediol (D5); AMS were poorly correlated with preoperative parameters. QoL and sexual symptoms significantly worsened after radical prostatectomy. Baseline bioavailable testosterone levels were significantly correlated with smaller changes on AMS somatic subscores postprostatectomy. These findings may be used to inform patients with newly diagnosed prostate cancer.

This study aims to investigate whether clinical and biological preoperative characteristics of patients who were to undergo radical prostatectomy were associated with impairment in patient-reported quality of life (QoL) and erectile dysfunction immediately before intervention. We evaluated patient-reported outcomes among 1019 patients (out of 1343) of the AndroCan study, willing to score the Aging Male Symptom (AMS) and the International Index of Erectile Function 5-item (IIEF-5) auto-questionnaires. Univariate linear regression and robust multiple regression were used to ascertain the relationship between demographic, clinical, and hormonal parameters and global AMS or IIEF-5 scores. As a result, most patients (85.1') of the Androcan cohort agreed to complete questionnaires. Significantly higher IIEF-5 global scores were found in non-Caucasian and obese patients, with larger waist circumference, metabolic syndrome, diabetes mellitus, cardiovascular disease, hypertension, high blood sugar, concomitant medications, and hypogonadism, while the AMS global score was significantly higher in patients with larger waist circumference, metabolic syndrome, high blood pressure, raised glycemia, and concomitant medication. The IIEF-5 global score was correlated to age, dehydroepiandrosterone (DHEA), fat mass percentage, and androstenediol (D5). The AMS global score was significantly correlated to DHEA, D5, and DHEA sulfate. Finally, the multivariate models showed that QoL and erectile function were significantly affected, before surgery, by symptoms and signs that are usually considered as pertaining to the metabolic syndrome, while sexual hormones are essentially correlated to erectile dysfunction.
