Abstract
BACKGROUND Empty pelvis syndrome (EPS) is a significant source of morbidity following pelvic exenteration (PE), but is undefined. EPS outcome reporting and descriptors of radicality of PE are inconsistent; therefore, the best approaches for prevention are unknown. To facilitate future research into EPS, the aim of this study is to define a measurable core outcome set, core descriptor set and written definition for EPS. Consensus on strategies to mitigate EPS was also explored. METHOD Three-stage consensus methodology was used: longlisting with systematic review, healthcare professional event, patient engagement, and Delphi-piloting; shortlisting with two rounds of modified Delphi; and a confirmatory stage using a modified nominal group technique. This included a selection of measurement instruments, and iterative generation of a written EPS definition. RESULTS One hundred and three and 119 participants took part in the modified Delphi and consensus meetings, respectively. This encompassed international patient and healthcare professional representation with multidisciplinary input. Seventy statements were longlisted, seven core outcomes (bowel obstruction, enteroperineal fistula, chronic perineal sinus, infected pelvic collection, bowel obstruction, morbidity from reconstruction, re-intervention, and quality of life), and four core descriptors (magnitude of surgery, radiotherapy-induced damage, methods of reconstruction, and changes in volume of pelvic dead space) reached consensus-where applicable, measurement of these outcomes and descriptors was defined. A written definition for EPS was agreed. CONCLUSIONS EPS is an area of unmet research and clinical need. This study provides an agreed definition and core data set for EPS to facilitate further research.

Abstract
Abstract
Introduction
Atrial Fibrillation (AF) catheter ablation carries high bleeding and thromboembolic risks, requiring a detailed assessment of overall risk-benefit profile regarding antithrombotic strategy. Vitamin K Anticoagulant (VKA) and Non-Vitamin K Antagonist Oral Anticoagulant (NOAC) have been used in the latest years in this setting, and with different interruption protocols periprocedural. Our goal was to evaluate the rate of acute adverse events (AAE) and compare them according to antithrombotic strategy used periprocedural, in a real-world basis.
Methods
A single-center retrospective study, including adult patients admitted to first AF catheter ablation, from 2004 to 2020. Different antithrombotic strategies (anticoagulation with VKA uninterrupted, anticoagulation with NOAC uninterrupted, no therapy or antiaggregation/interrupted ACO) were compared concerning the rate of any clinically relevant AAE; the composite of major AAE (hemopericardium and stroke/transient ischemic attack [TIA]) and minor AAE associated with vascular access. Descriptive statistics and logistic regression were used to compare groups according to the antithrombotic strategy with an alpha level of 0.05.
Results
Among the 868 patients included (mean age 59±12 yo, 67,5% [n=586] men), pulmonary vein isolation was performed under uninterrupted anticoagulation in 640 (73,7%), of which 595 patients with NOAC (68,5%) and 45 with VKA (5,2%). AF was paroxysmal, persistent and long-standing persistent in 63,4% (n=550), 21,4% (n=185) and 15,4% (n=133) patients, respectively. Mean CHADS-VASc score was 1,86±1,48. Over time there was a shift in the distribution of the type of antithrombotic therapy used, consistent with changes in recommendations (Graph 1).
The composite outcome occurred in 6,8% (n=62), including hemopericardium in 1,8% (n=16), stroke/TIA in 0,7% (n=6) and events related to vascular access in 1,4% (n=13) [Table 1]. No anticoagulation therapy or antiaggregation/interrupted ACO was more associated to the outcome, driven by major AAE, although the difference did not meet statistical significance (p=0,06) [Table 1]. No difference was found between VKA and NOAC group. Additionally, there was no diference in the incidence of hemorrhagic AAE since the implementation of an uninterrupted anticoagulation strategy periprocedural.
Conclusion
In our population of patients submitted to AF catheter ablation, an uninterrupted anticoagulation strategy is associated with lower rate of AAE, either with VKA or NOAC. Our real-world results are reassuring of the benefit of an uninterrupted strategy, and consistent with recent controlled trials.

Abstract
Abstract
Introduction
The definition of the quality of care in healthcare services is paramount to implement the resources necessary to grant the best quality of care according to the current guidelines. Recently, the European Society of Cardiology's guidelines for the management of acute coronary syndromes without ST segment elevation (NSTEMI) were published, and defined the quality indicators to be evaluated in such patients.
Purpose
To characterize the level of care given to the population of patients with NSTEMI included in the a national registry since 2011, according to the new guidelines directives.
Population and methods
We evaluated 12193 patients with NSTEMI. For each year the following variables were analyzed: age, gender, cardiovascular and non-cardiovascular comorbidities, clinical presentation (rhythm, blood pressure, Killip-Kimball Class), left ventricular ejection fraction (LVEF), treatment during admission and discharge, and time to invasive coronary angiography (ICA). Besides this, a comparing between years was made to analyze differences according to the quality indicators established in the guidelines.
Results
In 2019, 83.9% of patient with LVEF <40% were treated with IECA/ARA II and 80.6% were prescribed a betablocker at discharge. No statistically significant differences were found across the year with respect to IECA/ARA II at discharge (p=0.495), and beta-blocker at discharge (p=0.812). In terms of P2Y12 inhibitors during the hospital admission, there was a statistically significant increase in its use when comparing 2019 to 2014, 2015, 2016 and 2017 (p=0.019 for 2014 and p<0,001 the following years), with prescription in 90.4% of the patients in 2019. At discharge 88.3% of the patients were prescribed a P2Y12 inhibitor in 2019 and there was also a statistically significant increase in its prescription when compared to the previous years (from 2011 to 2017 with a p<0.001). When it comes to the prescription of statins at discharge there was a statistically significant difference between groups, driven mostly by an increase compared to the year 2012 (95.6% vs 90.8%, p=0.005). Only 16% of patients were subjected to ICA within 24h of admission during the year 2019. No statistically significant difference was found between other years (p>0.100 when comparing between years).
Discussion
The most striking feature that can be improved is the amount of patients subject to ICA within the first 24h after diagnosis. When it comes to the P2Y12 inhibitors it is also clear that there has been an increase in its prescription during the admission and at discharge. To sum up, it is clear that there is still some margin to improve care, of at least 10–20% in most parameters. This data portrays a picture of the measures and steps to take in order to provide the adequate care according to the latest guidelines.

Abstract
Abstract
Introduction
Iron deficiency was shown to affect functional capacity and ejection fraction in patients with heart failure and reduced ejection fraction. Myocardial infarction is an important cause of reduced left ventricular ejection fraction (LVEF). Moreover, there is some evidence of the iron deficiency as a factor to predict cardiovascular and non-cardiovascular mortality.
Purpose
Evaluate the presence of iron deficiency in patients with acute coronary syndromes (ACS) admitted to the intensive cardiac care unit and its eventual association with LVEF and mortality.
Population and methods
We performed a prospective study in which ACS patients were divided into groups according to the presence or absence of iron deficiency. We collected demographic data, comorbidities, as well as determination of troponin I, haemoglobin and criteria for absolute and functional iron deficiency (ID) and other data related to the use of mechanical ventilation, need for aminergic support, LVEF and death.
Results
From 148 patients we included 78 patients who met the criteria for being analysed. 49 patients had iron deficiency (51% had absolute iron deficiency and 49% had relative iron deficiency). There were no differences between groups in terms of myocardial infarction with or without ST segment elevation (p=0.609 and p=0.329, respectively), hypertension (p=0.926), diabetes (p=0.882), obesity (p=0.343), dyslipidaemia (p=0.482), smoking (p=0.876), valvular heart disease (p=0.888), acute and chronic renal failure (p=0.800 and p=0.888, respectively) and LVEF (p=0.886). There were no differences in need for aminergic support (p=0.984), ventilation (p=0.315) and death (p=0.704).
We found that in the sub-population of patients without anaemia (Hb>12g/dL), the proportion of patients with depressed LVEF (inferior to 50%) and relative iron deficiency was significantly higher than those with preserved LVEF (48.1 vs 13.8%, p=0.005). Furthermore, we also found that in this sub-population, patients with myocardial infarction without ST segment elevation had higher proportion of absolute iron deficiency (45.0 vs 19.4%, p=0.043).
Conclusion
Our study showed that the prevalence of iron deficiency in ACS patients is 62.9% (n=49). Moreover, in patients without anaemia, this results seems to point out that the presence of iron deficiency may be related with LVEF, at least during the acute event. Further studies with a higher sample size are warranted to either establish or discard this association. Furthermore, a follow-up of this patients can further enlighten us as to the role of iron deficiency in long term LVEF and mortality.

Abstract
OBJECTIVE To assess the general population's knowledge regarding the utility and availability of tools to diagnosis endometriosis, with a focus on ultrasound. DESIGN An international cross-sectional online survey study was performed between August and October 2019. SETTING AND POPULATION 5301 respondents, representing 73 countries. METHODS In all, 23 questions survey focused on knowledge of endometriosis diagnosis distributed globally via patient- and community-endometriosis groups using social media. MAIN OUTCOMES AND MEASURES Descriptive data of the knowledge of diagnostic tools for diagnosing endometriosis, including details about diagnosis using ultrasound. RESULTS In all, 84.0% of respondents had been previously diagnosed with endometriosis, 71.5% of whom had been diagnosed at the time of surgery. Ultrasound and MRI were the methods of diagnosis in 6.5% and 1.8%, respectively. A total of 91.8%, 28.8% and 16.6% of respondents believed surgery, ultrasound and MRI could diagnose endometriosis, respectively (more than one answer allowed). In those diagnosed by surgery, 21.7% knew about ultrasound as a diagnosis method, whereas in those diagnosed non-surgically, 51.5% knew (P < 0.001). In all, 14.7%, 31.1% and 18.2% stated superficial, ovarian and deep endometriosis could be diagnosed with ultrasound (32.9% stated they did not know which phenotypes of endometriosis could be diagnosed). Lastly, 58.4% of respondents do not believe they could access an advanced ultrasound in their region. CONCLUSIONS There is a limited appreciation for the role of non-surgical diagnostic tests for endometriosis among lay respondents to this survey. TWEETABLE ABSTRACT International survey shows limited awareness of lay respondents about non-surgical endometriosis diagnostic tools.

Abstract
Abstract
Background
While randomized clinical trials have demonstrated the superiority of coronary artery bypass grafting (CABG) over percutaneous coronary intervention (PCI) in patients with diabetes and multivessel coronary artery disease (CAD), there remains a paucity of observational evidence comparing these two modalities.
Methods
Clinical and administrative databases for Canada's most populous province, Ontario, were linked to obtain records of all patients with angiographic evidence of multivessel CAD (defined as: 2-vessel and 3-vessel disease) treated with either isolated CABG or PCI from October 2008 to March 2017. Left main disease was excluded in the primary analysis. Baseline characteristics of patients undergoing CABG and PCI were compared and 1:1 propensity score matching was performed to account for baseline differences. 30-day mortality was compared in the matched groups. Late mortality and the composite of major cardiovascular and cerebrovascular events (MACCE, consisting of stroke, myocardial infarction (MI), repeat revascularization, and death) were compared between the matched groups using a stratified log rank test and Cox-proportional hazards model. The individual non-fatal components of MACCE were compared using the Fine-Gray model that accounted for death as a competing risk. A secondary analysis that included patients with left main disease was also performed for the outcome of late mortality. A sensitivity analysis that excluded patients with acute coronary syndrome was also conducted for late mortality.
Results
A total of 9,395 and 4,016 patients underwent CABG and PCI respectively. Prior to matching, CABG patients were younger (65.7 vs 68.5 years, p<0.001), more likely male (78% vs 73%, p<0.001) and with more severe CAD. Propensity score matching based on 24 baseline covariates yielded 3,782 well-balanced pairs. There was no difference in early mortality between CABG and PCI (2.3% vs 2.5%, p=0.65). The rate of all-cause mortality over 8-years was significantly higher with PCI compared to CABG (Figure- HR: 1.35, 95% CI: 1.23–1.50). The cumulative incidence of MI (HR 1.91, 95% CI: 1.66–2.20) and need for repeat revascularization (HR: 4.06, 95% CI: 3.54–4.66) were significantly higher with PCI over 8 years. There was no difference in late stroke between PCI and CABG (stroke (HR: 0.85, 95% CI: 0.68–1.07). Overall MACCE was higher in PCI compared to CABG (HR: 1.94, 95% CI: 1.80–2.09). In our secondary analysis that included patients with left main disease, findings were robust and late mortality remained higher with PCI compared to CABG (HR: 1.42, 95% CI: 1.30–1.54). In a sensitivity analysis where patients with acute coronary syndrome at the time of presentation were excluded, late mortality remained higher with PCI (HR: 1.30, 95% CI: 1.12–1.49) in 2,028 matched pairs.
Conclusions
In patients with multivessel CAD and diabetes we observed improved long-term mortality and freedom from MACCE at 8-years with CABG compared to PCI.

Abstract
AIM At presentation, 15-20% of patients with rectal cancer already have synchronous liver metastases. The aim of this study was to determine the surgical and survival outcomes in patients with advanced rectal cancer who underwent combined pelvic exenteration and liver (oligometastatic) resection. METHOD Data from 20 international institutions that performed simultaneous pelvic exenteration and liver resection between 2007 and 2017 were accumulated. Primarily, we examined perioperative outcomes, morbidity and mortality. We also assessed the impact that margin status had on survival. RESULTS Of 128 patients, 72 (56.2%) were men with a median age of 60 years [interquartile range (IQR) 15 years]. The median size of the liver oligometastatic deposits was 2 cm (IQR 1.8 cm). The median duration of surgery was 406 min (IQR 240 min), with a median blood loss of 1090 ml (IQR 2010 ml). A negative resection margin (R0 resection) was achieved in 73.5% of pelvic exenterations and 66.4% of liver resections. The 30-day mortality rate was 1.6%, and 32% of patients had a major postoperative complication. The 5-year overall survival for patients in whom an R0 resection of both primary and metastatic disease was achieved was 54.6% compared with 20% for those with an R1/R2 resection (P = 0.006). CONCLUSION Simultaneous pelvic exenteration and liver resection is feasible, with acceptable morbidity and mortality. Simultaneous resection should only be performed where an R0 resection of both pelvic and hepatic disease is anticipated.

Abstract
Issue
Violence against women is a serious public health concern in Brazil; the country ranks 5th globally for femicide and has high rates of intimate partner violence. In response, a national policy created the House of the Brazilian Woman (HBW). HBWs aimed at caring for abused women, are staffed 24/7 with multi-disciplinary teams; cross-sectoral services include: psychosocial support; healthcare; specialized police; courts; public attorney's offices; temporary shelter; and access to financial support.
Description of the Problem
The purpose of this study was to characterize the preliminary impacts of the HBW of Curitiba. Based on mixed-methods participatory action-research, data were collected between 2018-2020. We present quantitative measures describing the individuals served and a thematic analysis of in-depth interviews with HBW staff.
Results
Since its opening, in 2016, the HBW of Curitiba has served around 50,000 users, including women and perpetrators. The most prevalent type of violence reported was psychological (67%, n = 14,343), followed by physical (25.8%, n = 5,531), economic (5.2%, n = 1,104) and sexual (2%, n = 428). Positive qualitative impacts perceived by staff were: 1) improved women's empowerment; 2) the importance of centralized resources; 3) acting as a support to ensure existing legal protections. The main challenges were: 1) high demand; 2) discontinuous care; 3) negative impacts on staff's health.
Lessons
The HBW of Curitiba is a key cross-sectoral service for abused women, part of a greater national policy to prevent violence and support women. Despite serving a large number of women in a short period of time challenges remain including integration with other parts of the network and considerations of staff burnout.
Key messages
Effective cross-sectoral policies for abused women are paramount for comprehensive women’s health. Having cross-sectoral services in just one place operating 24/7 has high impact for abused women.

Abstract
Abstract
Introduction
infective endocarditis(IE) is a high morbidity and mortality disease, and heart failure,central nervous system embolization and annular abscess account for common complications.Nevertheless,intracardiac fistula is rare and predicts higher mortality and urgency for surgery.
Case
84years old male patient,with an aortic bioprosthesis valve Perimount n23 since 2015,was admitted to internal medicine ward 3months before,due to Enterococcus faecalis bacteremia.at that time,transoesophageal echocardiography(TEE) revealed moderate to severe mitral valve(MV) regurgitation(vena contracta 0.7cm) and trivial tricuspid regurgitation,but did not showed any suggestive images of endocarditis.the patient was treated with 14days of amoxicillin-clavulanate.
On the current presentation,due to fadigue to mild physical activity and fever for 2weeks,he was admitted to cardiology ward for further investigation.blood cultures were positive for the previous agent,so antibiotherapy with ampicillin 12g/day and gentamicin 240mg id was started.TEE revealed thickening of aortic bioprosthesis’ leaflets with preserved systolic opening.aortic valve annulus thickening,mainly near the non-coronary cusp,was evident, without characteristic features of peri-annular abscess.on ventricular side of the prosthesis,there was a vegetation(10.7x10.8mm). a small nodule lesion,coherent with a second vegetation,was present on the MV’s posterior leaflet,without regurgitation’s worsening. a third one was observed on the septal leaflet of the tricuspid valve(7.3x6.5mm),which also caused an increasement in severity of the regurgitation,quantified as moderate.
On the sixth day,the patient presented with right arm paresis,so a brain CT was performed,showing an ischemic lesion on the left middle cerebral artery.Reevaluation,5days later,owing to new neurological changes,showed multiple acute vertebrobasilar embolic strokes.
As a result of poor medical response and embolic strokes,the patient was referred to surgical treatment. however, due to prohibitive surgical risk (euroscore 59%), the patient was refused.
After 6weeks of blood culture driven antibiotherapy,a reevaluation TEE revealed a periprosthetic pseudoaneurysm with small aorta-to-right atrium fistula.no vegetations were found.
Conclusion
rate complication of cardiac fistulae is high,60%of the patients develop heart failure and mortality rate is higher than 40%.although conservative treatment was addressed,after 8months discharge,the patient remains with few heart failure symptoms(NYHA classII).

Abstract
Abstract
Background
The efficacy, safety, and tolerability of an angiotensin receptor-neprilysin inhibitor (ARNi) in patients presenting with de novo heart failure (HF) has not been previously well-defined.
Methods
The PIONEER-HF trial was a prospective, multicenter, double-blind, active-controlled, randomized clinical trial which enrolled 887 patients (pts) at 129 sites in the United States. Pts with or without a history of prior HF and an ejection fraction (EF) <40% and a NT-proBNP >1600 pg/mL or BNP >400 pg/mL were eligible for participation no earlier than 24 hours while still hospitalized for acute decompensated HF (ADHF). Pts were randomly assigned 1:1 to in-hospital initiation of sacubitril/valsartan (S/V) titrated to 97/103 mg vs. enalapril titrated to 10 mg both by mouth twice daily for 8 weeks. We performed a pre-specified analysis in pts with de novo HF (i.e., defined as pts without a history of HF prior to the qualifying ADHF event).
Results
At the time of enrollment, 34% (N=303) had de novo HF. These pts experienced a similar improvement in NT-proBNP with S/V vs. enalapril (Ratio of geometric means 0.65, 95% Confidence Interval [CI] 0.53–0.81; p-value = 0.0002) compared to pts with worsening chronic HF (ratio 0.72 (0.63–0.83, p-value <0.0001) (Figure). In addition, the incidence of worsening renal function, hyperkalemia, and hypotension was comparable with S/V vs. enalapril regardless of whether they were hospitalized for de novo or worsening chronic HF. Finally, there was no interaction (p-value = 0.350) between previous HF status and the effect of S/V on the composite of cardiovascular death or rehospitalization for HF (de novo HF: Hazard Ratio [HR] 0.34, 95% CI 0.11–1.05 vs. worsening chronic HF: HR 0.60, 95% CI 0.39–0.93).
Conclusion
Among patients admitted for ADHF, irrespective of prior HF history, in-hospital initiation of an ARNi led to a greater reduction in natriuretic peptide levels, a comparable safety profile, and a significant improvement in clinical outcomes.

Abstract
Abstract
Introduction
The etiological diagnosis of cardiac arrhythmias is often difficult. Cardiac Magnetic Resonance (CMR) is the gold standard exam for anatomical and functional cardiac evaluation and it may be indicated in patients with ventricular arrhythmias when echocardiography does not provide an accurate assessment of left and right ventricles (LV, RV).
Purpose
The aim of this study was to determine the impact of CMR in the diagnosis and stratification of arrhythmic risk in patients with confirmed or suspected arrhythmias, as well as to describe the changes observed.
Methods
We performed a prospective registry over a 5-year period of all the patients with arrhythmias who underwent CMR for diagnostic and risk stratification purposes. We followed a protocol to evaluate both anatomically and functionally the ventricles and to look for the presence of late gadolinium enhancement (LGE).
Results
A total of 78 patients were included, of which 65% were male and a mean age of 46±17 years-old was observed. The indications for CMR evaluation of patients with confirmed or suspected arrhythmias were as follows: 33% (n=26) of the patients had very frequent premature ventricular complexes (PVC), 23% (n=18) had sustained ventricular tachycardia (VT), 17% (n=13) suspected structural heart disease with high arrhythmic potential, 12% (n=9) unexplained recurrent syncope, 6% (n=5) supraventricular tachycardia, 5% (n=4) non-sustained VT and 4% (n=3) aborted sudden cardiac death. Depressed ventricular ejection fraction (<50%) was present in 9% (n=7) for the LV and in 14% (n=11)for the RV. Dilation of the LV was found in 24% of the patients (n=19, mean LV volume: 115±4ml/m2) and RV dilation was present in only 1 patient who had right ventricle arrhythmogenic dysplasia (RVAD) (RV volume: 152ml/m2). Cardiac synchronization artifacts due to the presence of very frequent PVC compromised the calculation of v volumes in only 4% (n=3) of the patients. In total, 6% (n=5) had interventricular septum hypertrophy (mean 15±6g/m2), 10% (n=8) had a slight prolapse of the anterior leaflet of the mitral valve and 19% (n=15) had a dilated left auricle. LGE was present in 13% (n=10) and slight pericardium effusion was detected in 12% (n=9). CMR was considered normal in 65% (n=51), in 15% (n=12) we found nonspecific changes deserving follow-up and in 20% (n=15) it was possible to establish a diagnosis which was previously unknown: 5% (n=4) had hypertrophic cardiomyopathy, 4% (n=3) LV non-compaction, 4% (n=3) a myocarditis sequelae, 3% (n=2) RVAD, 3% (n=2) a myocardial infarction scar and 1 had non-ischemic dilated cardiomyopathy.
Conclusions
CMR is a technique with high spatial resolution, feasible and safe, which allowed an increase in diagnosis in 20% of the patients, thus contributing to the risk stratification of our study population with suspected high arrhythmic potential when the first-line complementary exams were inconclusive.

Abstract
The aim of the present study was to evaluate the effect of anti-Müllerian hormone (AMH), with and without FSH, on the in vitro development of isolated caprine preantral follicles, as well as follicular steroid production and mRNA levels of AMH, hormone receptors (AMH and FSH), CYP19A1 (cytochrome P450, family 19, subfamily A, polypeptide 1), CYP17 (cytochrome P450, family 17, subfamily A, polypeptide 1), HSD3B (3-beta-hydroxysteroid dehydrogenase) and Myc (myelocytomatosis oncogene). Isolated secondary follicles were cultured in minimum essential medium alpha (α-MEM+) alone or supplemented with 50ng mL-1 AMH and/or 100ng mL-1 FSH added sequentially on different days of culture. Follicles were cultured for a total of 18 days, with different media during the first (Days 0-9) and second (Days 10-18) halves of the culture period, resulting in six treatment groups, as follows: α-MEM+/α-MEM+, FSH/FSH, AMH/AMH, AMH+FSH/AMH+FSH, AMH/FSH, and FSH/AMH. Follicle development was evaluated on the basis of follicular growth, oocyte maturation and steroid secretion. There was a decrease in follicular growth rate in the AMH, AMH+FSH and AMH/FSH treatment groups compared with α-MEM+ and FSH treatment groups (P<0.05). However, the different culture conditions had no effect on rates of meiotic resumption and steroid secretion (P>0.05). Moreover, follicles cultured in the presence of FSH had lower levels of AMH receptor type II (AMHRII) mRNA compared with non-cultured control (freshly isolated follicles), and the AMH and AMH/FSH treatment groups. In conclusion, AMH reduces the follicular growth rate of isolated goat preantral follicles in vitro without affecting follicular survival.

Abstract
Inflammatory bowel disease (IBD) is associated with low bone mineral density (BMD). In this study, the association between disease severity and BMD in patients with IBD was evaluated. Associations between BMD and the Montreal classification, disease activity and drug therapy were also tested. A cross-sectional prevalence study with a comparison group was conducted. One hundred and twenty-eight patients were evaluated: 68 patients with ulcerative colitis (UC), and 60 with Crohn's disease (CD). The control group consisted of 67 healthy subjects. All patients and controls had BMD measured and in IBD patients, current medications, hospitalization, and disease location, extent and phenotype, according to the Montreal classification, were recorded. Multiple correspondence analysis was applied to evaluate categorical variables. In the CD group, most patients were diagnosed between 17–40 years of age. Ileocolonic and non-stricturing non-penetrating disease were the most frequent disease location and behavior, respectively. In UC patients, extensive colitis was the most frequent disease location. UC and CD patients were more likely to have osteopenia than controls (OR=14.93/OR=24.38, respectively). In the CD group, male patients, perianal disease, penetrating behavior and age at diagnosis >40 years were associated with low BMD. Taking azathioprine and infliximab also seemed to be associated with osteopenia. In the UC group, we observed an association between low BMD and male patients, left colitis, corticosteroid use and hospitalization. Disease activity was not associated with osteopenia or osteoporosis in CD and UC patients. Disease severity seems to be associated with osteopenia in IBD patients.

Abstract
One of the major difficulties faced by popcorn breeders is the negative correlation between popping expansion (PE) and grain yield (GY). It is necessary to overcome this difficulty to obtain promising genotypes. One helpful tool in this process is a selection index because it allows multiple features of interest to be selected. Thus, the present study proposes a new and comprehensive selection index applied in 169 half-sib families in UEM-Co1 and UEM-Co2 composites during two cycles of recurrent selection. An experiment was conducted in a 13 x 13 lattice square in the 2004/2005 and 2006/2007 crop years in Maringá, Paraná State, and PE and GY were evaluated. To calculate Fi statistics, the following relative importance (RI) assignments were used: 0.5 for both PE and GY, and 0.70 and 0.30 for PE and GY, respectively. Families were classified according to Fi values such that Fi = 0 indicated that genotypes met the average of those selected by direct selection, Fi < 0 indicated that genotypes fell below the average of those selected, and Fi > 0 indicated that genotypes exceeded the average of those selected. Thus, desirable values of Fi were positive, indicating that the selected families were higher than those families that would be selected by direct selection for both traits. Therefore, we concluded that the novel Fi statistic was satisfactory for family selection because simultaneous and higher gains for both traits in both composites were obtained.

Abstract
The aims of this study were to evaluate the localization, by immunohistochemistry, of the anti-Müllerian hormone (AMH) in goat ovaries and to investigate its effects on the in vitro survival and development of caprine pre-antral follicles enclosed in fragments of ovarian tissue. Pre-antral follicles were cultured in vitro for 1 or 7 days in α-MEM(+) in the absence or presence of kit ligand (KL; 50 ng/ml, positive control) or AMH (50 or 150 ng/ml). The results showed that AMH was localized in oocytes and granulosa cells from the primordial follicle to antral follicle stages. Addition of AMH maintained the percentage of developing follicles, similar to that in the uncultured control; however, the percentage of developing follicles was significantly lower than that in the cultured control and KL. Nonetheless, addition of AMH to the culture medium did not affect survival rates and follicular growth. In conclusion, this study demonstrated that the expression of AMH varies according to the compartment and stage of follicular development. Furthermore, AMH inhibits the activation of caprine primordial follicles.

Abstract
To develop a preantral follicular culture system that will support follicular growth and result in fertilizable oocytes, we conducted an experiment designed to determine the best medium for culture. In our preliminary experiment, we compared 2 common base media used for porcine oocytes: α-minimal essential medium and NCSU-23. Ovaries were collected from prepubertal gilts at a local abattoir and transported to the laboratory in saline solution (0.9% NaCl) maintained at 30–35°C. The ovaries were cut into small pieces (1–3 mm), and preantral follicles were isolated mechanically. Preantral follicles from 280 to 300 μm in diameter were collected into a small dish containing medium TCM199 (Lonza 12–117F) supplemented with 5% fetal bovine serum. The follicles were transferred from the collecting medium to the culture medium that consisted of base medium (NCSU23 or α-minimal essential medium) supplemented with 3.5 μg mL–1 of insulin, 10 μg mL–1 of transferrin, 100 μg mL–1 of l-ascorbic acid, 7.5% porcine serum, and 1.5 ng mL–1 of FSH. The follicles were randomly distributed to the different experimental treatments and cultured for 6 days in 24-well cell culture plates, with 3 follicles per well in 280 μL of culture medium. The culture was carried out at 38.5°C in 5% CO2 in air. Culture medium was changed every 2 days with freshly prepared medium. The diameters of follicles were measured every 2 days, and each follicle was photographed and evaluated at 20× magnification. Forty-two follicles per group were analysed and collected in 4 replicates. Data were statistically analysed with ANOVA using the Generalized Linear Model (GLM) procedure (SPSS, version 18, SPSS Inc., Chicago, IL, USA), where the independent variable was the sample (group and day of culture). Tukey's post hoc test was used to perform multiple comparisons; the α level was set at 0.05. All data were expressed as quadratic means with standard error of the means. Only the antrum formation was evaluated by chi-square test. The results, reported in Table 1, show that there was no statistical differences between follicle size between NCSU23 or α-minimal essential media, but at Day 6 there was a positive trend (P = 0.08). Otherwise, when we compared the size inside the groups, we observed that the preantral follicles grew more in α-minimal essential media than in NCSU23. The percentages of antrum formation were 65 v. 76% (NCSU23 and α-minimal essential media, respectively). These results support the use of α-minimal essential media because it had a positive effect on the antrum formation, and that after Day 4 some follicles could undergo a regression phase. Future studies will be necessary to evaluate the molecular status and the hormone production.

Abstract
This study investigated the effect of insulin concentration on the in vitro culture of equine preantral follicles enclosed in ovarian tissue. Ovarian tissue samples were immediately fixed (noncultured control) or cultured for 1 or 7 days in α-MEM(+) supplemented with 0 ng/mL, 10 ng/mL, or 10 μg/mL insulin. Ovarian tissues were processed and analyzed by classical histology. Culture medium samples were collected after 1 and 7 days of culture for steroid and reactive oxygen species (ROS) analyses. The percentage of morphologically normal follicles was greater (P < 0.001) in insulin-treated groups after 1 day of culture; likewise, more (P < 0.02) normal follicles were observed after 7 days of culture in medium supplemented with 10-ng/mL insulin. Furthermore, an increase (P < 0.01) in developing (transition, primary, and secondary) follicles between Days 1 and 7 of culture was observed only with the 10-ng/mL insulin treatment. ROS production after 1 or 7 days of culture was lower (P < 0.0001) in medium with 10-ng/mL insulin than the other treatments. Ovarian tissues containing preantral follicles were able to produce estradiol and progesterone after 1 and 7 days of culture; however, treatments did not differ in steroid production. In conclusion, the use of a physiological concentration (10 ng/mL) of insulin rather than the previously reported concentration (10 μg/mL) for in vitro culture of equine preantral follicles improved follicular survival and growth and lowered oxidative stress. Results from this study shed light on new perspectives for producing an appropriate medium to improve equine preantral follicle in vitro survival and growth.

Abstract
The present study evaluated the efficiency of using 2 culture media developed for mice and for goats in the in vitro preantral follicle culture of each species. Murine and caprine secondary follicles were cultured in vitro with human recombinant follicle-stimulating hormone (murine medium) or with bovine recombinant follicle-stimulating hormone in association with growth hormone (caprine medium). The results showed that murine follicles cultured in caprine medium had lower (P < 0.05) rates of follicular survival and growth, whereas for caprine follicles, these variables were not affected by the type of medium used (P > 0.05). After in vitro maturation, a higher (P < 0.05) number of oocytes that resumed meiosis were observed in the murine medium for both species. In contrast, only in the caprine species estradiol production was significantly superior when the caprine medium was used. Higher progesterone production was observed in the presence of the murine medium only for murine follicles (P < 0.05). In conclusion, murine and caprine preantral follicles cultured under the same in vitro culture medium conditions respond differently; caprine oocytes grown in vitro in the presence of the murine medium show the greatest developmental competence among the tested combinations. Therefore, under the present experimental conditions, the mouse follicle culture has proved be a good model for the development of new culture media for caprine preantral follicles.

Abstract
The aims of this study were the following: (1) to define an optimal period for the IVC of isolated caprine preantral follicles, (2) to verify the relationship between follicular morphology (intact, extruded, and degenerate follicles) and estradiol production, and (3) to evaluate the effects of the bidimensional (2D) and three-dimensional (3D) culture systems on the in vitro development of caprine preantral follicles. Three experiments were performed. In experiments 1 and 2, the isolated secondary follicles were cultured for 18, 24, and 30 days or 30, 36, and 42 days, respectively. In experiment 3, the optimal culture period from experiment 2 was used for 2D and 3D culture systems. After culture, the oocytes were submitted to IVM. The morphological integrity, antral cavity formation rates, follicular diameter, presence of healthy, grown oocytes (≥110 μm), rates of resumption of meiosis, and estradiol concentrations were evaluated. In experiment 1, the percentage of oocytes that resumed meiosis was higher in oocytes cultured for 30 days (48.84%) than in oocytes cultured for 18 and 24 days (15% and 20.93%, respectively). In experiment 2, the percentage of oocytes that resumed meiosis was significantly higher in oocytes cultured for 30 and 36 days (47.5% and 50%, respectively) than in oocytes cultured for 42 days (20%). The estradiol concentrations on Day 12 of culture were similar for normal and extruded follicles and higher than those observed in degenerate follicles at the end of the culture period. In conclusion, the 36-day culture period resulted in the highest rates of meiosis resumption. In addition, because the loss of follicular integrity affects the patterns of estradiol production, follicular integrity is a good predictor of follicular quality.

Abstract
The presence of pharmaceutical drugs in the environment is an important field of toxicology, since such residues can cause deleterious effects on exposed biota. This study assessed the ecotoxicological acute and chronic effects of two anticholinesterasic drugs, neostigmine and pyridostigmine in Daphnia magna. Our study calculated 48 h-EC50 values for the immobilization assay of 167.7 μg L(-1) for neostigmine and 91.3 μg L(-1) for pyridostigmine. In terms of feeding behavior, we calculated a 5 h-EC50 for filtration rates of 7.1 and 0.2 μg L(-1) for neostigmine and pyridostigmine, respectively; for the ingestion rates, the calculated EC50 values were, respectively, 7.5 and 0.2 μg L(-1) for neostigmine and pyridostigmine. In the reproduction assay, the most affected parameter was the somatic growth rate (LOECs of 21.0 and 2.9 μg L(-1) for neostigmine and pyridostigmine, respectively), followed by the fecundity (LOECs of 41.9 and 11.4 μg L(-1) for neostigmine and pyridostigmine, respectively). We also determined a 48 h-IC50 for cholinesterase activity of 1.7 and 4.5 μg L(-1) for neostigmine and pyridostigmine, respectively. These results demonstrated that both compounds are potentially toxic for D. magna at concentrations in the order of the μg L(-1).

Abstract
The aim of this study was to investigate the effects of melatonin and follicle-stimulating hormone (FSH) on the in vitro culture of goat preantral follicles. Ovarian fragments were cultured for 7 d in α-minimum essential medium (α-MEM(+)) containing melatonin (100, 250, 500, or 1,000 pM), FSH (50 ng/mL), or a combination of the 2 hormones and further analyzed by histology and transmission electron and fluorescent microscopy. The results showed that after 7 d of culture, tissues cultured in α-MEM(+) alone or supplemented with FSH alone, melatonin (500 and 1,000 pM), or the combination of FSH and melatonin (1,000 pM) maintained percentages of normal preantral follicles similar to the fresh control. In contrast to the noncultured tissues, the percentage of developing follicles was increased under all culture conditions after 7 d (P < 0.05). The addition of 1,000 pM melatonin associated with FSH to the culture medium increased follicular and oocyte diameters compared with α-MEM(+) alone after 7 d of culture (P < 0.05). Ultrastructural and fluorescent analyses confirmed the integrity of follicles cultured with 1,000 pM of melatonin plus FSH for 7 d. In conclusion, this study demonstrated that the interaction between melatonin and FSH maintains ultrastructural integrity and stimulates further growth of cultured caprine preantral follicles.

Abstract
The rapid detection of extended-spectrum beta-lactamases (ESBLs) is a challenge for most clinical microbiology laboratories because inaccurate identification of ESBL producers has important clinical implications for both antibiotic treatment and infection control. The aim of our study was to develop a rapid detection assay of ESBL producers based upon flow cytometric analysis. Antimicrobial susceptibility testing followed by molecular characterization of bla(TEM) , bla(SHV) or bla(CTX-M) genes was performed on clinical isolates (41 ESBL positive and 20 ESBL negative) and isolates expressing well-characterized beta-lactamases, including ESBLs (n = 13), plasmid AmpCs (n = 3), oxacillinases (n = 5) and carbapenemases (n = 3). Additionally, two ATCC strains recommended by CLSI for susceptibility testing were used as controls. The flow cytometry analysis protocol involved an incubation of bacterial cells with different concentrations of ceftazidime (1, 2 and 4 mg/L) and cefotaxime (4, 8 and 16 mg/L) for 1 and 2 hours, in the presence and absence of clavulanic acid; subsequently, cells were stained with the fluorescent dye Bis-(1,3-dibutylbarbituric acid) trimethine oxonol [DiBAC(4) (3)], a lipophilic anion able to diffuse across depolarized membranes. Additionally, CFU counts were performed. Susceptible isolates displayed increased fluorescence after 1 hour of incubation; conversely, the increase of the depolarized population was only observed after incubation with clavulanic acid associated with ceftazidime or cefotaxime in ESBL producers. An excellent correlation was obtained between the number of non-depolarized bacteria quantified by flow cytometry and by conventional CFU assays. A novel, accurate and fast flow cytometric assay is available to detect the presence of ESBLs.

Abstract
This study aimed to test different protocols for the extraction of microbial DNA from the coral Mussismilia harttii. Four different commercial kits were tested, three of them based on methods for DNA extraction from soil (FastDNA SPIN Kit for soil, MP Bio, PowerSoil DNA Isolation Kit, MoBio, and ZR Soil Microbe DNA Kit, Zymo Research) and one kit for DNA extraction from plants (UltraClean Plant DNA Isolation Kit, MoBio). Five polyps of the same colony of M. harttii were macerated and aliquots were submitted to DNA extraction by the different kits. After extraction, the DNA was quantified and PCR-DGGE was used to study the molecular fingerprint of Bacteria and Eukarya. Among the four kits tested, the ZR Soil Microbe DNA Kit was the most efficient with respect to the amount of DNA extracted, yielding about three times more DNA than the other kits. Also, we observed a higher number and intensities of DGGE bands for both Bacteria and Eukarya with the same kit. Considering these results, we suggested that the ZR Soil Microbe DNA Kit is the best adapted for the study of the microbial communities of corals.
