Abstract
Mission readiness is critical to the operational success of the United States (US) military and includes having a healthy and fit fighting force. Service members and their dependents have access to a wide range of sexual and reproductive health services with no out-of-pocket costs. Despite this access, negative outcomes such as sexually transmitted infections (STIs) and unintended pregnancy persist. Semi-structured, in-depth interviews were conducted with service members and stakeholders (e.g. medical providers). Interviews explored the individual, interpersonal, organizational, and institutional factors that inform sexual norms, behaviors, and healthcare experiences in the US military. Interview transcripts were coded manually; data were summarized for themes related to unique aspects of military culture and healthcare affecting sexual and reproductive health. Twenty-five (25) service members and 15 stakeholders completed interviews. Four themes emerged: 1) despite free access, both general and military-specific barriers to sexual and reproductive healthcare persist; 2) general and military-specific cultural norms apply to sexual behavior and care seeking; 3) sexual and reproductive health-related norms can be perceived as confusing and contradictory within the military; and 4) resources addressing sexual assault are ubiquitous in military settings, but resources addressing prevention of STIs and unintended pregnancy are limited. Both general and military-specific norms, behavior, and healthcare experiences need to be considered in clinical care, public health campaigns, and other efforts to promote sexual and reproductive health in military settings.

Abstract
Medical record data was extracted from a sexually transmitted infection (STI) clinic in Providence, Rhode Island to characterize trends in Neisseria gonorrhoeae (GC) infection and explore risk factors. Of 16,601 clinical encounters, 6% (n=991) tested GC positive: 5.28 GC case rate (per 100 encounters) in the first two years of data collection (2015-2016) and 7.04 in the last two years (2020-2021). Analysis suggested a single linear trend line over time (p<.05). Overall, in more recent years, patients were older and more like to identify as male, Black, and Hispanic/Latino, as well as to have reported a previous STI, current symptoms, and specific risk behaviors. GC-positive patients in 2020-2021 were older and more like to identify as female and Black compared to 2015-2016. Lower rates of condom use were especially salient among female patients. These findings may reflect GC trends in the community.

Abstract
This study aims to uncover potent cytochrome P450 (CYP) and epoxide hydrolase (EH) metabolites implicated in Aβ and/or tau-induced neurodegeneration, independent of neuroinflammation, by utilizing Caenorhabditis elegans (C. elegans) as a model organism. Our research reveals that Aβ and/or tau expression in C. elegans disrupts the oxylipin profile, and epoxide hydrolase inhibition alleviates the ensuing neurodegeneration, likely through elevating the epoxy-to-hydroxy ratio of various CYP-EH metabolites. In addition, our results indicated that the Aβ and tau likely affect the CYP-EH metabolism of PUFA through different mechanism. These findings emphasize the intriguing relationship between lipid metabolites and neurodegenerations, in particular, those linked to Aβ and/or tau aggregation. Furthermore, our investigation sheds light on the crucial and captivating role of CYP PUFA metabolites in C. elegans physiology, opening up possibilities for broader implications in mammalian and human contexts.

Abstract
BACKGROUND To include, sustain, and retain HIV-focused early career faculty from groups historically excluded from biomedical research, the Providence/Boston Center for AIDS Research (CFAR) conducted focus groups and individual interviews with early and mid-career faculty to discern their needs. METHODS We conducted focus groups and interviews with 15 faculty at institutions affiliated with Providence/Boston CFAR from groups underrepresented in biomedical research. The discussion was guided using the domains of an Asset Bundle Model encompassing scientific human capital, social capital, and financial capital. RESULT Participants' identities, including their race, ethnicity, gender, sexual orientation, and being a parent affected their vision of themselves as scientists. Participants reported confusion or limited training on or access to resources for professional development, hiring staff, meeting NIH reporting requirements, international research, support for working parents, sabbaticals, and addressing workplace conflict or unsupportive work environments. Some described feeling like they were a burden on their mentors who seemed overextended. They identified attributes of effective mentors, such as believing in and investing in the mentee; having the requisite content area expertise and self-confidence; being able to identify mentees needs and meet them where they are; and being consistent, communicative, respectful, and kind. They described a need for additional education and support preresearch and postresearch grant award management. CONCLUSIONS To learn how to equitably serve all interested in HIV research, CFARs should engage and include perspectives from scientists who have historically been excluded from biomedical research. Our future work will test, implement, and disseminate the ideas generated by these focus group discussions.

Abstract
BACKGROUND Metastatic colorectal cancer (mCRC) patients tend to have modest benefits from molecularly driven therapeutics. Patient-derived tumor organoids (PDTOs) represent an unmatched model to elucidate tumor resistance to therapy, due to their high capacity to resemble tumor characteristics. MATERIALS AND METHODS We used viable tumor tissue from two cohorts of patients with mCRC, naïve or refractory to treatment, respectively, for generating PDTOs. The derived models were subjected to a 6-day drug screening assay (DSA) with a comprehensive pipeline of chemotherapy and targeted drugs against almost all the actionable mCRC molecular drivers. For the second cohort DSA data were matched with those from PDTO genotyping. RESULTS A total of 40 PDTOs included in the two cohorts were derived from mCRC primary tumors or metastases. The first cohort included 31 PDTOs derived from patients treated in front line. For this cohort, DSA results were matched with patient responses. Moreover, RAS/BRAF mutational status was matched with DSA cetuximab response. Ten out of 12 (83.3%) RAS wild-type PDTOs responded to cetuximab, while all the mutant PDTOs, 8 out of 8 (100%), were resistant. For the second cohort (chemorefractory patients), we used part of tumor tissue for genotyping. Four out of nine DSA/genotyping data resulted applicable in the clinic. Two RAS-mutant mCRC patients have been treated with FOLFOX-bevacizumab and mitomycin-capecitabine in third line, respectively, based on DSA results, obtaining disease control. One patient was treated with nivolumab-second mitochondrial-derived activator of caspases mimetic (phase I trial) due to high tumor mutational burden at genotyping, experiencing stable disease. In one case, the presence of BRCA2 mutation correlated with DSA sensitivity to olaparib; however, the patient could not receive the therapy. CONCLUSIONS Using CRC as a model, we have designed and validated a clinically applicable methodology to potentially inform clinical decisions with functional data. Undoubtedly, further larger analyses are needed to improve methodology success rates and propose suitable treatment strategies for mCRC patients.

Abstract
STUDY QUESTION Does GnRH-agonist trigger offer similar maturity rate (MR) in low and normal responders compared to high responders in women undergoing planned oocyte cryopreservation, for whom even a small risk of ovarian hyperstimulation syndrome (OHSS) may not be acceptable? SUMMARY ANSWER GnRH-agonist is an appropriate choice for final maturation of oocytes in planned oocyte cryopreservation, regardless of response to stimulation or risk of ovarian hyperstimulation syndrome. WHAT IS KNOWN ALREADY Numerous studies have demonstrated the utility of GnRH-agonist trigger for the prevention of ovarian hyperstimulation in high-responder in vitro fertilization cycles. Limited data exist supporting its use in normal or low responders, or in non-infertile women undergoing planned oocyte cryopreservation. STUDY DESIGN, SIZE, DURATION Retrospective cohort study of 1189 subjects including all planned oocyte cryopreservation cycles performed at a large, single center, oocyte cryopreservation program from April 2016 to December 2018. PARTICIPANTS/MATERIALS, SETTING, METHODS A total of 1680 cycles were included in the study. A total of 57.1% (959/1680) utilized GnRH-agonist for trigger. Demographic and clinical data were collected from the medical record. Maturation rate was calculated for the entire cohort, and by trigger type, using the quotient of Metaphase II (MII) oocytes and retrieved oocytes. A sub-cohort of GnRH-agonist trigger cycles were categorized by peak estradiol (E2) levels and maturation rates compared between groups. Associations were made using Student's t test, ANOVA, Mann-Whitney U and Kruskal-Wallis, where appropriate. A sample size calculation for 90% power with a significance of 5% to detect non-inferiority of <0.05 from a 0.75 maturity rate between subjects with E2 > 3000 pg/mL and E2 < 3000 pg/mL demonstrated the need for at least 116 cycles per group. MAIN RESULTS AND THE ROLE OF CHANCE Mean MR was 0.71 ± 0.19 overall, and 0.73 ± 0.18 in the sub-cohort of GnRH-agonist trigger cycles. A total of 611 cycles (63.7%) had peak E2 < 3000, and 331 (34.5%) had E2 > 3000. No significant difference in maturity rate was noted between cycles with E2 levels >3000 pg/mL and <3000 pg/mL (0.72 ± 0.19 vs. 0.74 ± 0.14, P = 0.18), confirming the non-inferiority of maturity rates with GnRH-agonist triggers in cycles with peak E2 < 3000 pg/mL. While lower mean oocytes retrieved and mean MII oocytes were associated with lower peak E2 levels, maturity rate did not significantly differ amongst E2 level groups. Cycles with E2 < 1000 pg/mL had lower MR irrespective of trigger type. LIMITATIONS, REASONS FOR CAUTION The retrospective nature cannot entirely exclude selection biases, confounding factors or additional variables that could not be accounted for or were not collected by the electronic medical record. Given the nature of planned oocyte cryopreservation, studies of ongoing pregnancy rates and birth outcomes will naturally be delayed. Lastly, the study population was limited to women undergoing planned oocyte cryopreservation; therefore, the results may not be generalizable to women undergoing in vitro fertilization. WIDER IMPLICATIONS OF THE FINDINGS This is the first study specifically comparing the efficacy of GnRH-agonist in patients at lower risk for OHSS to those at high risk, as well the first study evaluating GnRH-agonist's efficacy specifically in planned oocyte cryopreservation cycles.

Abstract
Background:Cutaneous manifestations are observed in 59–85% of patients with SLE but less than 5% developed BSLE. In the GLADEL cohort, the prevalence is 0.41%. BSLE literature in children is scarceObjectives:to describe the clinical characteristics of the patients with BSLEMethods:series of cases between 2010-2019 of two reference centers. The cases met Camisa and Grimwood criteria for BSLEResults:5 cases had bullous lesions that resolved with residual hypopigmentation. One case had focal seizure and other patient had arthritis with leukopenia and thrombocytopenia. 2 patients had proteinuria <500 mg/24 hours. There were no cases of lupus nephritis. The median SLEDAI-2K score was 12 (IR: 8-17). All had ANAs in titers greater than 1:160 and four had anti-DNA (+). 5 patients had anti-RNP and 4 had anti-Sm. One case had anti-Ro/anti-La. All presented low C3 and 80% had low C4. 80% had ESR ≥20 mm/hour and CRP greater than 0.5 mg/dl in 60%. All presented clinical response with glucocorticoids and dapsone; one patient had methemoglobinemia that improved. At 3 months, the blisters did not recur in 4 patients except one case that presented relapse due to inadherence.Histologically, the most common finding was subepidermal blisters with neutrophils in the papilar dermis. DIF showed linear deposits of Igs and complement in 4 cases and granular deposits in one case; IgG/IgM were in 5 of the samples. IgA was positive in 60% and C3 in 80%Conclusion:In this series, BSLE was associated with neuropsychiatric, joint and haematological involvement in 40% of patients, without lupus nephritis. Such abnormalities had a parallel course to skin involvement, without recurrences. BSLE tends to have a single-phase behavior and in children unlike adults, severe renal involvement is uncommonReferences:[1]Pons-Estel GJ, et al.

Abstract
PURPOSE To characterize the likelihood of cryopreserving enough oocytes for 50%, 60%, or 70% estimated live birth rate (eLBR) with 1-2 planned oocyte cryopreservation (Pl-OC) cycles. METHODS We performed a retrospective cohort study utilizing all patients completing ≥ 1 Pl-OC cycle from 2016 to 2018 at a large single-center OC program. Subjects were categorized by age at retrieval and number of cycles. We extrapolated age-based oocyte thresholds for 50%, 60%, or 70% eLBR from previously published data. We calculated the proportion of subjects overall, and for each age group, whose number of frozen oocytes was greater than or equal to their age-based threshold for a 50%, 60%, or 70% eLBR after 1 and 2 cycles. OR for 60% eLBR with one cycle was calculated for age and AMH cutoff values and corroborated with logistic regression. RESULTS A total of 1241 subjects, completing 1799 Pl-OC cycles, were included. With one cycle, 66% (819/1241) achieved ≥ 50% eLBR and 51% (634/1241) achieved 70% eLBR. With two cycles, 79.6% (988/1241) attained ≥ 50% eLBR and 65.5% (813/1241) achieved 70% eLBR. Achieving 50%, 60%, or 70% eLBR with 1-2 cycles was significantly associated with both age (p < 0.001) and AMH (p < 0.001). Age < 37.5 and AMH > 1.995 were independently associated with attaining 60% eLBR with one cycle (age: OR 13.73; 95%CI 9.16-20.57, p < 0.001; AMH: OR 7.32; 95% CI 5.50-9.76, p < 0.001). CONCLUSIONS Younger age and higher AMH were associated with achieving 50%, 60%, or 70% eLBR thresholds with Pl-OC. Nevertheless, almost all subjects were successfully able to preserve enough oocytes for ≥ 50% eLBR in 1-2 cycles.

Abstract
In vitro durability tests of cardiovascular devices are often used to evaluate the potential for fretting damage during clinical use. Evaluation of fretting damage is important because severe fretting can concentrate stress and lead to the loss of structural integrity. Most international standards call for the use of phosphate buffered saline (PBS) for such tests although there has been little evidence to date that the use of PBS is appropriate in terms of predicting the amount of fretting damage that would occur in vivo. In order to determine an appropriate test media for in vitro durability tests where fretting damage is being evaluated, we utilized an in vitro test that is relevant to cardiovascular devices both in terms of dimensions and materials (nitinol, cobalt-chromium, and stainless steel) to characterize fretting damage in PBS, deionized water (DIW), and heparinized porcine blood. Overall, tests conducted in blood were found to have increased levels of fretting damage over tests in DIW or PBS, although the magnitude of this difference was smaller than the variability for each test media. Tests conducted in DIW and PBS led to mostly similar amounts of fretting damage with the exception of one material combination where DIW had greatly reduced damage compared to PBS and blood. Differences in fretting damage among materials were also observed with nitinol having less fretting damage than stainless steel or cobalt-chromium. In general, evaluating fretting damage in PBS or DIW may be appropriate although caution should be used when selecting test media and interpreting results given some of the differences observed across different materials.

Abstract
INTRODUCTION The objective of this study was to assess the utility of novel verbal fluency scores for predicting conversion from mild cognitive impairment (MCI) to clinical Alzheimer's disease (AD). METHOD Verbal fluency lists (animals, vegetables, F, A, and S) from 107 MCI patients and 51 cognitively normal controls were transcribed into electronic text files and automatically scored with traditional raw scores and five types of novel scores computed using methods from machine learning and natural language processing. Additional scores were derived from structural MRI scans: region of interest measures of hippocampal and ventricular volumes and gray matter scores derived from performing ICA on measures of cortical thickness. Over 4 years of follow-up, 24 MCI patients converted to AD. Using conversion as the outcome variable, ensemble classifiers were constructed by training classifiers on the individual groups of scores and then entering predictions from the primary classifiers into regularized logistic regression models. Receiver operating characteristic curves were plotted, and the area under the curve (AUC) was measured for classifiers trained with five groups of available variables. RESULTS Classifiers trained with novel scores outperformed those trained with raw scores (AUC 0.872 vs 0.735; P < .05 by DeLong test). Addition of structural brain measurements did not improve performance based on novel scores alone. CONCLUSION The brevity and cost profile of verbal fluency tasks recommends their use for clinical decision making. The word lists generated are a rich source of information for predicting outcomes in MCI. Further work is needed to assess the utility of verbal fluency for early AD.

Abstract
We have sequenced the complete genomes of 72 individuals affected with early-onset familial Alzheimer's disease caused by an autosomal dominant, highly penetrant mutation in the presenilin-1 (PSEN1) gene, and performed genome-wide association testing to identify variants that modify age at onset (AAO) of Alzheimer's disease. Our analysis identified a haplotype of single-nucleotide polymorphisms (SNPs) on chromosome 17 within a chemokine gene cluster associated with delayed onset of mild-cognitive impairment and dementia. Individuals carrying this haplotype had a mean AAO of mild-cognitive impairment at 51.0 ± 5.2 years compared with 41.1 ± 7.4 years for those without these SNPs. This haplotype thus appears to modify Alzheimer's AAO, conferring a large (~10 years) protective effect. The associated locus harbors several chemokines including eotaxin-1 encoded by CCL11, and the haplotype includes a missense polymorphism in this gene. Validating this association, we found plasma eotaxin-1 levels were correlated with disease AAO in an independent cohort from the University of California San Francisco Memory and Aging Center. In this second cohort, the associated haplotype disrupted the typical age-associated increase of eotaxin-1 levels, suggesting a complex regulatory role for this haplotype in the general population. Altogether, these results suggest eotaxin-1 as a novel modifier of Alzheimer's disease AAO and open potential avenues for therapy.

Abstract
BACKGROUND Prostaglandin (PG) signaling has been implicated in embryonic implantation in several animal species including humans; however, this knowledge has not yet been clinically translated. The objective of this work is to investigate whether PGE2 and PGF2α in endometrial fluid (EF) can be used as biomarkers of human embryonic implantation. PATIENTS AND METHODS Lipidomic profile of human EF (n = 173) obtained through natural cycles, hormonal replacement therapy, controlled ovarian stimulation, and refractory endometrium induced by the insertion of an intrauterine device was analyzed by liquid chromatography and tandem mass spectrometry. Immunohistochemistry, Western blotting, immunolocalization of PG receptors on mouse embryos, embryo adhesion assay, pharmacological interventions, and statistical analysis were conducted. RESULTS PGE2 and PGF2α concentrations increased significantly in the human EF during the window of implantation in natural cycles and assisted reproductive technologies patients undergoing in vitro fertilization and ovum donation. This profile was abrogated in the refractory endometrium. We also demonstrated that PGE2 and PGF2α synthases are located in the endometrial epithelium being hormonally regulated during the window of implantation, and PG receptors are expressed in the trophoectoderm and inner cell mass of mouse blastocysts. Using an in vitro model of embryo adhesion, we demonstrated that inhibition of PGE2 and PGF2α or PG receptors (EP2 and FP) prevents embryo adhesion, which can be overcome by adding these molecules back or using their agonists. Finally, in a pilot study, we demonstrated that PGE2 and PGF2α levels from EF 24 hours prior to embryo transfer could predict pregnancy outcome. CONCLUSIONS Our results suggest that PGE2 and PGF2α concentrations 24 hours prior to embryo transfer are potential noninvasive biomarkers of endometrial receptivity.

Abstract
The study assessed the effect of soil slope on Mycobacterium avium subsp. paratuberculosis transport into rainwater runoff from agricultural soil after application of M. avium subsp. paratuberculosis-contaminated slurry. Under field conditions, 24 plots of undisturbed loamy soil 1 by 2 m(2) were placed on platforms. Twelve plots were used for water runoff: 6 plots at a 3% slope and 6 plots at a 15% slope. Half of the plots of each slope were treated with M. avium subsp. paratuberculosis-contaminated slurry, and half were not treated. Using the same experimental design, 12 plots were established for soil sampling on a monthly basis using the same spiked slurry application and soil slopes. Runoff following natural rainfall was collected and analyzed for M. avium subsp. paratuberculosis, coliforms, and turbidity. M. avium subsp. paratuberculosis was detected in runoff from all plots treated with contaminated slurry and one control plot. A higher slope (15%) increased the likelihood of M. avium subsp. paratuberculosis detection but did not affect the likelihood of finding coliforms. Daily rainfall increased the likelihood that runoff would have coliforms and the coliform concentration, but it decreased the M. avium subsp. paratuberculosis concentration in the runoff. When there was no runoff, rain was associated with increased M. avium subsp. paratuberculosis concentrations. Coliform counts in runoff were related to runoff turbidity. M. avium subsp. paratuberculosis presence/absence, however, was related to turbidity. Study duration decreased bacterial detection and concentration. These findings demonstrate the high likelihood that M. avium subsp. paratuberculosis in slurry spread on pastures will contaminate water runoff, particularly during seasons with high rainfall. M. avium subsp. paratuberculosis contamination of water has potential consequences for both animal and human health.

Abstract
OBJECTIVE To determine the efficacy of topical 0.3% ciprofloxacin in reducing conjunctival biota in patients undergoing cataract surgery. PATIENTS AND METHODS Experimental, prospective, randomized, controlled and single-blind study. Forty-six eyes of 46 patients were randomized into 2 groups, the study group (n=23) received topical 0.3% ciprofloxacin one day before surgery for six times, and on the day of the surgery one drop every 15minutes starting one hour before surgery until 3 doses were completed. The control group (n=23) did not receive any antibiotics. For both groups for the surgical field 10% povidone-iodine was applied. Samples from the conjunctiva were taken at four different times and then cultured on solid media (chocolate agar, blood agar) and enrichment broth (thioglycolate). The aqueous humor samples were also cultured in thioglycolate. The presence of bacteria was identified quantitatively and qualitatively, and the frequency of contamination was measured by considering the presence of bacteria in liquid and solid culture media. The number of colony forming units (CFU) was counted in the solid culture medium. RESULTS Positive cultures were obtained in 82.6% and 78.2% of the patients in the study and control groups, respectively, before the administration of 0.3% ciprofloxacin. The administration of 0.3% ciprofloxacin significantly reduced the CFU compared to the control group (P<.05). Immediately after the use of povidone-iodine, the proportion of patients with a positive culture decreased to 21.7% in the study group, and 8.7% in the control group. At the end of the surgery, this percentage was 26% and 30.4%, respectively. The most common isolated pathogen was negative-coagulase Staphylococcus (66.7%). CONCLUSION The administration of 0.3% ciprofloxacin reduces conjunctival bacterial load in the preoperative period. However, it was unable to eradicate the bacteria completely. The administration of povidone-iodine reduced conjunctival biota in 50%-70% of patients undergoing cataract surgery.

Abstract
Recently, a new procedure for the analysis of sperm DNA fragmentation has been developed for human and different mammalian species (Sperm-Halomax®), based on the sperm chromatin dispersion test (SCDt); however, no studies has been performed specifically on canine frozen–thawed-stressed semen but is there for cooled semen. The aim of this work was to assess the effect of a stressor (24 h in an oven at 38°C) on canine frozen–thawed semen using the SCDt to resemble what happens in the female reproductive tract. For this purpose, ejaculates were collected by digital manipulation from 4 healthy beagle dogs and the sperm-rich fraction of the ejaculates from 3 different dogs was pooled each time. All the pooled semen samples (n = 4) used presented physiological values concerning to routine semen parameters (motility, morphology, and sperm concentration). After evaluation, semen samples were centrifuged and the sperm pellet resuspended to a final concentration of 100 × 106 sperm mL–1 in 2 steps with CaniPRO Freeze (Minitub, Tiefenbach, Germany). Sperm were slowly cooled to 5°C and then loaded into 0.5-mL plastic straws. After that, straws were frozen in liquid-nitrogen vapours for 10 min and stored into a nitrogen tank. Straws were thawed in a water bath (30 s/37°C) and incubated for 24 hours at 38°C before analysis. The sperm DNA fragmentation was assessed in fresh semen and frozen–thawed-stressed samples using the Sperm-Halomax® commercial kit specifically developed for canine semen (Halotech DNA SL, Madrid, Spain) following the manufacturer’s instructions. Slides were stained for green fluorescence staining and 500 sperm per slide were counted using fluorescence microscopy. The sperm DNA fragmentation index (%) was compared between fresh and frozen–thawed-stressed semen samples by ANOVA. Results were expressed as mean ± standard error of the mean. The results obtained showed that subjecting thawed semen to 24 h in an oven at 38°C significantly increased (P < 0.05) DNA fragmentation compared with fresh semen (2.7% ± 0.2 v. 1.4 ± 0.1%). The stress factor was performed to simulate the viability of canine thawed sperm (12–24 h) when a bitch is inseminated with frozen semen. It would be interesting to perform further studies to relate sperm DNA fragmentation and fertility of frozen–thawed canine semen. In conclusion, frozen–thawed-stressed semen samples increased the sperm DNA fragmentation index measured using a SCDt. Further studies are needed to relate sperm DNA fragmentation with fertility rates or cryopreservation success.

Abstract
Chromosomal abnormalities were described as a possible cause of embryo failures in cattle, even more so when they are in vitro produced. It has been widely demonstrated that the post-fertilization culture environment affects the frequency of blastomeric aneuploidies. However, the literature concerning the effect of the oocyte maturation techniques on in vitro-produced embryos is scarce. The aim of this study was to determine the effect of homologous bovine follicular fluid (BFF) as a possible replacement for commercial sera in the appearance of chromosomal abnormalities on early IVF-produced embryos. Cumulus–oocyte complexes obtained from ovarian puncture were maturated in modified bicarbonate-buffered TCM-199 media, supplemented with glutamine, sodium pyruvate, FSH, LH, oestradiol, and gentamicin in three different groups. Two treatments were performed: 1) base media supplemented with BFF, obtained aseptically from follicles between 4 and 10 mm in diameter (10 and 20%), and 2) a control group, with base media supplemented with 10% FCS without BFF. After 20 h of culture at 38.5°C in a 5% CO2 humid atmosphere, cumulus–oocyte complexes from both treatments were fertilized in IVF media and then cultured for 72 h in SOF media, according to our laboratory techniques. A total of 152 early embryos were cytogenetically evaluated following our standard laboratory techniques. Developed embryos were individually fixed onto a slide, disaggregated into blastomeres with acetic acid, and stained with Giemsa solution. Chromosomal numerical abnormalities were evaluated in each embryo by direct observation at 1250× magnification using a bright field microscope. Results were statistically compared among treatments by the expected proportion test. No significant differences (P > 0.05) were found between different culture media on the percentages of normal diploid embryos or each kind of numerical abnormality. According to our results (Table 1), the use of homologous follicular fluid as a supplement on the oocyte maturation media did not influence the appearance of abnormal complements in the embryos produced compared with the use of FCS. In conclusion, homologous follicular fluid may be considered a valid serum replacement in the maturation media on IVF-produced bovine embryos.

Abstract
Single-layer centrifugation (SLC) with EquipureTM Bottom Layer has been used to enhance the quality of stallion semen samples; however, no studies have been performed on donkeys. The aim of this study was to determine if SLC with EquipureTM Bottom Layer improves kinematic parameters on frozen–thawed donkey sperm. Semen was collected from 4 Andalusian donkeys by artificial vagina. Three ejaculates from each donkey were centrifuged with EquiproTM, supernatant was removed, and pellet was re-extended in the freezing medium GentTM to a final concentration of 200 × 106 spermatozoa per milliliter. Sperm were slowly cooled to 5°C for 2 h, loaded in 0.5-mL plastic straws, and frozen in liquid-nitrogen vapors. After at least one week of storage, straws were thawed in a water bath at 37°C for 30 s. After thawing, semen samples were divided in 2 aliquots: aliquot 1 was used as such (control) and aliquot 2 was processed by SLC using EquipureTM Bottom Layer. Computer-assisted sperm analysis was performed, and sperm kinematics total motility (%), progressive motility (%), curvilinear velocity (VCL; µm s–1), velocity straight line (VSL; µm s–1), velocity average path (VAP; µm s–1), linearity (LIN; %), straightness (STR; %), wobble (WOB; %), lateral head displacement (ALH; µm), and beat cross frequency (BCF; Hz) were statistically compared using GLM model between frozen–thawed semen samples processed or not with EquipureTM. Results were expressed as mean ± standard error. Significant differences (P < 0.05) were found between SLC-selected and unselected semen for total motility (77.44 ± 5.83 v. 58.89 ± 6.07), progressive motility (76.88 ± 4.52 v. 56.59 ± 5.44), VCL (137.50 ± 0.75 v. 133.0 ± 0.99), LIN (69.43 ± 0.31 v. 68.23 ± 0.41), STR (78.45 ± 0.29 v. 76.90 ± 0.37), WOB (85.06 ± 0.18 v. 83.91 ± 0.26), ALH (2.76 ± 0.01 v. 2.44 ± 0.01), and BCF (9.13 ± 0.05 v. 8.53 ± 0.06), respectively. No significant differences were observed for VSL (102.89 ± 0.70 v. 104.32 ± 0.95) and VAP (123.21 ± 0.71 v. 121.50 ± 0.98). Most of the computer-assisted sperm analysis parameters used in the present study have been previously identified as reliable markers of sperm motility in relation to sperm quality and fertility. It has also been reported that VCL appears to be critical for the formation of the sperm reservoir and penetration of the zona pellucida. In addition, other variables improved in the SLC-selected samples have been described as measure of progressivity (LIN, STR) and spermatozoa vigor (BCF, ALH). These preliminary results suggest an additional option for improving sperm quality in donkey semen doses. In conclusion, SLC with EquipureTM can be used to enhance kinematic parameters on frozen–thawed donkey sperm.

Abstract
The hallmark of Alzheimer's disease (AD) is declarative memory loss, but deficits in semantic fluency are also observed. We assessed how semantic fluency relates to cortical atrophy to identify specific regions that play a role in the loss of access to semantic information. Whole-brain structural magnetic resonance imaging (MRI) data were analyzed from 9 Normal Control (NC)(M=76.7, SD=5.6), 40 Mild Cognitive Impairment (MCI) (M=74.4, SD=8.6), and 10 probable AD (M=72.4, SD=8.0) subjects from the Alzheimer's Disease Neuroimaging Initiative (ADNI). They all were administered the Category Fluency (CF) animals and vegetables tests. Poorer semantic fluency was associated with bilateral cortical atrophy of the inferior parietal lobule (Brodman areas (BA) 39 and 40) and BA 6, 8, and 9 in the frontal lobe, as well as BA 22 in the temporal lobe. More diffuse frontal associations were seen in the left hemisphere involving BA 9, 10, 32, 44, 45, and 46. Additional cortical atrophy was seen in the temporoparietal (BA 37) and the right parastriate (BA 19, 18) cortices. Associations were more diffuse for performance on vegetable fluency than animal fluency. The permutation-corrected map-wise significance for CF animals was pcorrected=0.01 for the left hemisphere, and pcorrected=0.06 for the right hemisphere. The permutation-corrected map-wise significance for CF vegetables was pcorrected=0.009 for the left hemisphere, and pcorrected=0.03 for the right hemisphere. These results demonstrate the profound effect of cortical atrophy on semantic fluency. Specifically, tapping into semantic knowledge involves the frontal lobe in addition to the language cortices of the temporoparietal region.

Abstract
Density gradient centrifugation with PureSperm® (PureSperm® 40+PureSperm® 80; Nidacon International, Mölndal, Sweden) has been satisfactorily used to enhance the quality of dog semen samples; however, no studies have been performed on the effect of single layer centrifugation (SLC) with PureSperm® on frozen–thawed dog semen. The aim of this study was to investigate if SLC with PureSperm® 80 can improve the post-thaw semen quality of dog. Semen from 5 dogs was collected by digital manipulation. Two ejaculates from each dog were centrifuged with Tris-based extender, supernatant was removed, and sperm pellet was suspended to a final concentration of 300–400×106spermmL–1 with CaniPROTM Freeze A plus 20% egg yolk at 22°C. Extended semen was cooled to 5°C within an hour and then diluted to a final concentration of 150–200×106spermmL–1 in CaniPROTM Freeze B plus 20% egg yolk at 5°C, loaded in 0.5-mL plastic straws and frozen horizontally in ranks placed 4cm above the surface of liquid nitrogen vapors for 10min, after which they were directly placed in liquid nitrogen. After 24 to 48h of storage, straws were thawed in a water bath at 37°C for 30s. After thawing, semen samples were divided in 2 aliquots: one of them was used as control and the other one was processed by SLC PureSperm® 80. Assessment of sperm motility (assessed by computerized-assisted semen analysis), morphology (Diff-Quick staining), and viability [triple fluorescent stain of propidium iodine/isothiocyanate-labeled peanut (Arachis hypogaea) agglutinin/Rhodamine 123] were evaluated in control and treated semen samples. Data were studied by ANOVA. Results are expressed as mean ± SEM. Significant (P<0.001) differences were found between SLC-treated and control semen for sperm motility (percentage of total motile spermatozoa: 93.65±0.05 v. 83.79±0.13; percentage of progressive motile spermatozoa: 79.38±6.66 v. 54.61±16.11), morphology (86.45±0.01 v. 83.51±0.01), and viability (percentage of viable sperm with an intact acrosome: 58.32±0.04 v. 36.50±0.17; percentage of viable sperm with an acrosome reaction: 2.81±0.01 v. 9.74±0.21). Based on our results, we can conclude that SLC with PureSperm® 80 is an alternative and successful method for improving the quality of frozen–thawed dog spermatozoa, selecting good-quality spermatozoa (motile, morphologically normal, viable, and acrosome intact spermatozoa) from the rest of the semen sample.

Abstract
Several studies on sperm cooling and cryopreservation have been done in horses; however, only a few them have been developed in donkeys. In addition, no studies have been performed to freeze cooled stored donkey semen. Therefore, the aim of this study was to determine if it is possible to freeze donkey sperm after 24 h of cool storage. Semen was collected from 4 Andalusian donkeys by artificial vagina. After collection, each sample was separated into 2 aliquots; one of them was immediately frozen (t0) and the other one was cooled and stored before freezing (t24). The cryopreservation procedure consisted of a previous dilution of semen with EquiPro™. After that, semen was centrifuged and the sperm pellet resuspended with Gent® extender plus ethylene glycol (4%) to achieve a final concentration of 100 × 106 sperm mL–1. Sperm was slowly cooled to 5°C, loaded in 0.5-mL plastic straws and frozen in LN vapours. The second aliquot (t24) was diluted with Gent® extender to a final concentration of 50 × 106 sperm mL–1 and then cooled and stored at 5°C for 24 h. After that, cooled semen samples were cryopreserved following the same procedure as described above. Straws were thawed in a water bath at 37° for 30 s. Computer-assisted sperm motility analysis was performed. Total motility (TM), progressive motility (PM), and the following kinematic parameters: velocity curvilinear (VCL; µm s–1), velocity straight line (VSL; µm s–1), velocity average path (VAP; µm s–1), linearity (LIN; %), straightness (STR; %), wobble (WOB; %), amplitude of lateral head displacement (ALH; µm), and beat cross frequency (BCF; Hz) were compared between treatments by ANOVA. Results were expressed as mean ± standard error. Significant differences (P < 0.05) were found between treatments (t0 v. t24) for TM (63.76 ± 4.75 v. 51.67 ± 3.69), PM (36.01 ± 3.19 v. 27.24 ± 2.72), VCL (77.29 ± 0.65 v. 67.56 ± 0.78), VSL (58.50 ± 0.61 v. 52.11 ± 0.76), VAP (67.82 ± 0.64 v. 59.41 ± 0.79), LIN (57.90 ± 0.33 v. 59.53 ± 0.32), STR (70.39 ± 0.30 v. 72.43 ± 0.41), WOB (75.64 ± 0.22 v. 75.48 ± 0.32), ALH (1.88 ± 0.09 v. 1.69 ± 0.10), and BCF (6.28 ± 0.04 v. 6.51 ± 0.06). These preliminary results showed significant differences between cryopreservation at 0 and 24 h post-cooling; however, understanding that direct freezing is better in terms of sperm motility, cryopreservation of cooled stored semen could still be considered good according to the values obtained for sperm motility parameters after thawing. In our opinion, sperm centrifugation before cooling probably improve the results of cryopreservation 24 h post-cooling, due to the negative effect of seminal plasma on sperm viability during storage. In addition, the analysis of other sperm parameters would be useful to check more accurately differences between treatments. In conclusion, sperm motility parameters were higher in donkey semen samples immediately frozen after collection in comparison to semen samples cryopreserved after 24 h of cooling storage. Further studies are needed to improve cooling and cryopreservation procedures for freezing cooled stored donkey semen.

Abstract
BACKGROUND Cancer patients receiving chemotherapy are at increased risk for thrombosis. Apixaban, a factor Xa inhibitor, is oral and does not require laboratory monitoring. OBJECTIVES A pilot study was conducted to evaluate whether apixaban would be well tolerated and acceptable in cancer patients receiving chemotherapy. PATIENTS/METHODS Subjects receiving either first-line or second-line chemotherapy for advanced or metastatic lung, breast, gastrointestinal, bladder, ovarian or prostate cancers, cancer of unknown origin, myeloma or selected lymphomas were randomized to 5 mg, 10 mg or 20 mg once daily of apixaban or placebo in a double-blind manner for 12 weeks. Use of the study drug began within 4 weeks of the start of chemotherapy. The primary outcome was either major bleeding or clinically relevant non-major (CRNM) bleeding. Secondary outcomes included venous thromboembolism (VTE) and grade III or higher adverse events related to the study drug. Thirty-two patients received 5 mg, 30 patients 10 mg, 33 patients 20 mg, and 30 patients placebo. In these groups, there were 0, 0, 2 and 1 major bleeds, respectively. The corresponding data for CRNM bleeds were 1, 1, 2, and 0. The rate of major bleeding in the 93 apixaban patients was 2.2% (95% confidence interval 0.26-7.5%). There were no fatal bleeds. Three placebo patients had symptomatic VTE. CONCLUSIONS Apixaban was well tolerated in our study population. These results support further study of apixaban in phase III trials to prevent VTE in cancer patients receiving chemotherapy.

Abstract
e20514 Background: Cancer patients receiving chemotherapy, biologic, and molecular targeted therapies are at increased risk of venous thromboembolism (VTE). Currently available anticoagulants (ACs) are not well suited to prevent VTE in such patients. Vitamin K antagonist oral ACs require frequent lab monitoring and low molecular weight heparins require daily subcutaneous injection. There is concern for bleeding with ACs. Apixaban (A) is a new antithrombotic agent which inhibits activated coagulation Factor X, is taken orally, and does not require lab monitoring. Trials to prevent post-operative VTE in orthopedic surgery showed that A was effective and safe. We wanted to assess the feasibility of A in cancer. Methods: In a randomized phase II trial, patients with metastatic cancer on 1st or 2nd line chemotherapy received study drug once daily for 12 weeks; either 5, 10 or 20 mg of A, or placebo. The primary outcome measure was the proportion of patients remaining free of major bleeding (MB), clinically relevant non-major bleeding (CRNMB), VTE, and grade ≥3 adverse events considered to be probably/definitely related to study drug (AE*). After 125 patients were recruited, the sponsor eliminated further randomization to the 10 and 20 mg arms, to add experience with the 5 mg dose currently under evaluation for VTE prevention in other conditions. Data on the first 125 patients are reported. Results: The study population was 50% male; 88% had ECOG performance status 0 or 1. The most common cancers were breast, colon, pancreas, and myeloma. 23% had liver metastases. Approximately 80% of A patients completed 12 weeks of treatment. The numbers of patients with events were: Conclusions: Apixiban was well tolerated in patients with advanced cancer on chemotherapy. Major bleeding, thrombosis, and drug-related SAEs were very low. These results support further study of A in phase III trials for VTE prevention in cancer patients. [Table: see text] [Table: see text]

Abstract
This study used multi-frequency bioimpedance spectroscopy (BIS) of the arm and whole body to estimate muscle mass (MM) and subcutaneous adipose tissue (SAT) in 31 hemodialysis (HD) patients comparing these results with magnetic resonance imaging (MRI) and body potassium ((40)K) as gold standards. Total body and arm MM (MM(MRI)) and SAT (SAT(MRI)) were measured by MRI. All measurements were made before dialysis treatment. Regression models with the arm (aBIS) and whole body (wBIS) resistances were established. Correlations between gold standards and the BIS model were high for the arm SAT (r(2) = 0.93, standard error of estimate (SEE) = 3.6 kg), and whole body SAT (r(2) = 0.92, SEE = 3.5 kg), and for arm MM (r(2) = 0.84, SEE = 2.28 kg) and whole body MM (r(2) = 0.86, SEE = 2.28 kg). Total body MM and SAT can be accurately predicted by arm BIS models with advantages of convenience and portability, and it should be useful to assess nutritional status in HD patients.
