Abstract
Introduction. Lateral flow test (LFTs) have been used as an alternative to reverse transcription quantitative PCR (RT-qPCR) in point-of-care testing. Despite their benefits, the sensitivity of LFTs may be low and is affected by several factors. We have previously reported the feasibility of using direct lysis of individual or pools of saliva samples from symptomatic and asymptomatic patients as a source of viral genomes for detection by RT-qPCR.Hypothesis. Direct lysed saliva is more sensitive than antigen tests to detect severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in samples from children.Aim. Our goals here were to valuate the specificity and sensitivity of the PanBio COVID-19 antigen rapid test device (Ag-RTD) compared with RT-qPCR of direct lysed saliva.Methodology. We evaluated the performance of the PanBio COVID-19 Ag-RTD in comparison to RT-qPCR direct lysed saliva from paired samples of 256 symptomatic and 242 asymptomatic paediatric patients.Results. Overall, although there were no differences in the specificity (96.6%), we found a lower sensitivity (64.3%) of the PanBio Ag-test RTD compared to saliva in both symptomatic and asymptomatic patients. In addition, the sensitivity of PanBio was not correlated with the viral load present in the samples.Conclusion. Our data highlight the benefits of using RT-qPCR and saliva samples for SARS-CoV-2 detection, particularly in paediatric patients.

Abstract
OBJECTIVES This study was designed to investigate the response to chemotherapy of supradiaphragmatic disease diagnosed by preoperative imaging. As secondary objectives, oncologic outcomes of patients affected by supradiaphragmatic disease and their pattern of recurrence were also evaluated. METHODS Data of consecutive patients with newly diagnosed FIGO stage IV (for supradiaphragmatic disease) epithelial ovarian cancer undergoing either primary debulking surgery or neoadjuvant chemotherapy plus interval debulking surgery between 2004 and 2021, were retrospectively collected. All patients were preoperatively evaluated by chest/abdominal CT scan or 18F-FDG PET/CT preoperatively and at follow-up to evaluate response to chemotherapy. At follow-up visits, site of recurrence diagnosed by imaging techniques was systematically recorded as it occurred. Progression-free and overall survival were measured by using Kaplan-Meier and Cox models. RESULTS A total of 130 patients was included in this study with a median (range) follow-up of 32.9 (12.8-176.7) months. Complete or partial response was achieved in most of the patients after 3 cycles (77.7%) and 6 cycles (85.4%) of chemotherapy. At follow-up, recurrence occurred in 96 (73.8%) patients and the main site of recurrence was abdomen only in 64 (66.7%) patients. At multivariate analysis, residual disease after surgery was the only variable influencing survival outcomes. CONCLUSIONS Supradiaphragmatic disease respond to chemotherapy in most patients affected by advanced EOC and recurrence mainly occurs in the abdomen. Results from this study confirms that abdominal optimal cytoreduction is the main surgical goal in the treatment of women affected by FIGO stage IV EOC.

Abstract
The absence of standardized molecular profiling to differentiate uterine leiomyosarcomas versus leiomyomas represents a current diagnostic challenge. In this study, we aimed to search for a differential molecular signature for these myometrial tumors based on artificial intelligence. For this purpose, differential exome and transcriptome-wide research was performed on histologically confirmed leiomyomas (n = 52) and leiomyosarcomas (n = 44) to elucidate differences between and within these two entities. We identified a significantly higher tumor mutation burden in leiomyosarcomas vs. leiomyomas in terms of somatic single-nucleotide variants (171,863 vs. 81,152), indels (9491 vs. 4098), and copy number variants (8390 vs. 5376). Further, we discovered alterations in specific copy number variant regions that affect the expression of some tumor suppressor genes. A transcriptomic analysis revealed 489 differentially expressed genes between these two conditions, as well as structural rearrangements targeting ATRX and RAD51B. These results allowed us to develop a machine learning approach based on 19 differentially expressed genes that differentiate both tumor types with high sensitivity and specificity. Our findings provide a novel molecular signature for the diagnosis of leiomyoma and leiomyosarcoma, which could be helpful to complement the current morphological and immunohistochemical diagnosis and may lay the foundation for the future evaluation of malignancy risk.

Abstract
Low temperature in winter depresses rates of photosynthesis, which, in evergreen plants, can exacerbate imbalances between light absorption and photochemical light use. Damage that could result from increased excess light absorption is minimized by the conversion of excitation energy to heat in a process known as energy dissipation, which involves the de-epoxidized carotenoids of the xanthophyll cycle. Overwintering evergreens employ sustained forms of energy dissipation observable even after lengthy periods of dark acclimation. Whereas most studies of photoprotective energy dissipation examine one or a small number of species; here, we measured the levels of sustained thermal energy dissipation of seventy conifer taxa growing outdoors under common-garden conditions at the Red Butte Garden in Salt Lake City, Utah, U.S.A. (forty nine taxa were also sampled for needle pigment content). We observed an extremely wide range of wintertime engagement of sustained energy dissipation; the percentage decrease in dark-acclimated photosystem II quantum efficiency from summer to winter ranged from 6 to 95%. Of the many pigment-based parameters measured, the magnitude of the seasonal decrease in quantum efficiency was most closely associated with the seasonal increase in zeaxanthin content expressed on a total chlorophyll basis, which explained only slightly more than one-third of the variation. We did not find evidence for a consistent wintertime decrease in needle chlorophyll content. Thus, the prevailing mechanism for winter decreases in solar-induced fluorescence emitted by evergreen forests may be decreases in fluorescence quantum yield, and wintertime deployment of sustained energy dissipation likely underlies this effect.

Abstract
OBJECTIVES The neutropenic murine thigh infection model was used to assess the effectiveness of IID572, a novel β-lactamase inhibitor, in rescuing piperacillin activity against bacterial strains expressing various β-lactamase enzymes. METHODS Mice (n = 4/group) were inoculated with Enterobacteriaceae or Staphylococcus aureus bacterial strains expressing a range of β-lactamases via intramuscular injection. Two hours after bacterial inoculation, subcutaneous treatment with piperacillin/IID572 or piperacillin/tazobactam every 3 h was initiated. Animals were euthanized via CO2 24 h after the start of therapy and bacterial cfu (log10 cfu) per thigh was determined, and the static dose was calculated. RESULTS In a dose-dependent manner, piperacillin/IID572 reduced the thigh bacterial burden in models established with Enterobacteriaceae producing class A, C and D β-lactamases (e.g. ESBLs, KPC, CMY-2 and OXA-48). Piperacillin/IID572 was also efficacious against MSSA strains, including one producing β-lactamase. Static doses of piperacillin/IID572 were calculable from animals infected with all strains tested and the calculated static doses ranged from 195 to 4612 mg/kg/day piperacillin, the active component in the combination. Of the 13 strains investigated, a 1 log10 bacterial reduction was achieved for 9 isolates and a 2 log10 reduction was achieved for 3 isolates; piperacillin/tazobactam was not efficacious against 6 of the 13 isolates tested. CONCLUSIONS In contrast to tazobactam, IID572 was able to rescue piperacillin efficacy in murine thigh infection models established with β-lactamase-producing strains of Enterobacteriaceae and S. aureus, including those expressing ESBLs or serine carbapenemases.

Abstract
Abstract
Introduction
Prior studies have shown a morning circadian preference for African Americans compared to Non-Hispanic whites, but prior research has shown that self-reported sleep timing is delayed in African Americans compared to whites. No prior studies have evaluated this difference in sleep timing using objective measures of habitual sleep such as actigraphy.
Methods
We analyzed the sleep data from the Multi-Ethnicity Study of Atherosclerosis (MESA), a multi-site community-based cohort with both self-reported and actigraphic measures of habitual sleep variables. Self-reported sleep timing, chronotype as measured by the modified Horne-Ostberg Morningness-Eveningness Questionnaire (MEQ) and actigraphic sleep timing were examined using logistic regression and independent t-tests.
Results
1,430 participants had self-reported sleep data, and 1,405 participants had complete actigraphy data as well. There was no self-reported difference in circadian preference between African Americans and whites (mean MEQ score 17.1 ± 3.6 vs. 17.0 ± 4.0). African Americans were 76% more likely to report a bedtime after midnight on weekdays (odds ratio [OR] 1.8, 95% confidence interval [CI] 1.4, 2.3, p<0.001), and 50% more likely on weekends (OR 1.5, 95% CI 1.2, 1.9, p=0.001) as compared to whites. Actigraphic data showed similar results. African Americans were 80% more likely to have actigraphic sleep onset after midnight on weekdays (OR 1.8, 95% CI 1.4, 2.2) and 137% more likely (OR 2.4,95% CI 1.9, 3.0, p<0.001) on weekends as compared to whites. Actigraphic mid-sleep time was delayed 42 (95% CI 20, 64, p<0.001) minutes on weekdays and 24 (95% CI 6,42, p=0.01) minutes on weekends in African Americans compared to whites.
Conclusion
African Americans had delayed sleep timing compared to whites even though no significant racial differences in chronotype were present. Delayed sleep timing in African Americans may be related to factors other than self-reported circadian preference.

Abstract
Objective Early-stage ovarian cancer might represent an ideal disease scenario for sentinel lymph node application. Nevertheless, the published experience seems to be limited. Our objective was to assess the feasibility and safety concerns of sentinel lymph node biopsy in patients with clinical stage I–II ovarian cancer. Methods We conducted a prospective cohort study of 20 patients with histologically confirmed ovarian cancer. 99mTc and indocyanine green were injected into both the utero-ovarian and infundibulopelvic ligament stump, if they were present, during surgical staging. An intraoperative gamma probe and near-infrared fluorescence imaging were used to detect the sentinel lymph nodes. Inclusion criteria included: >18 years of age, suspicious adnexal mass (unilateral or bilateral) at ultrasound and CT imaging or confirmed ovarian tumor after previous surgery (unilateral or bilateral salpingo-oophorectomy with or without hysterectomy). Adverse events were recorded through postoperative day 30. The primary trial end point was to report adverse events related to the technique, including the use of 99mTc and ICG intraperitoneally, as well as the feasibility of the technique. Results A total of 20 patients were included in the analysis. Sentinel lymph nodes were detected in 14/15 (93%) pelvic and all 20 (100%) para-aortic regions. Five patients did not have utero-ovarian injection because of prior hysterectomy. The mean time from injection to sentinel lymph node resection was 53±15 min (range; 30–80). The mean number of harvested sentinel lymph nodes was 2.2±1.5 (range; 0–5) lymph nodes in the pelvis and 3.3±1.8 (range; 1–7) lymph nodes in the para-aortic region. There were no adverse intraoperative events, nor any within the 30 days of follow-up related with the technique. Conclusion Sentinel lymph node mapping in early-stage ovarian cancer is feasible without major intraoperative or < 30 days safety concerns. (NCT03452982). Trial registration number ClinicalTrials.gov, NCT03452982.

Abstract
Aims:Dual diagnosis of schizophrenic disorders and drug abuse/dependence are increasing due to more frequent use of cannabis and cocaine. It is important to differentiate between primary schizophrenia with associate drug abuse/dependence and drug-induced psychosis. The objective is to detect neuropsychological differences between drug users and non-users in schizophrenia patients, which could be used as diagnostic tools.Method:We conduct one case-control study on 12 schizophrenia out-patients (10 male) with vital history of drug abuse/dependence (mainly cannabis and cocaine) and one control group of 18 schizophrenia out-patients (12 male) who never used illegal drugs (global age mean: 32.8 years; SD:7.2). It was applied one neuropsychological battery sensitive to the neuropsychological deficit frequent in schizophrenia: WAIS-III, BADS, WCST, Colour Trails, Trail Making A and B, BVRT, California Verbal Learning Test (spanish version: TAVEC). Variables was summarized determining Z values and principal components. It was constructed one Logistic Regression Model to determinate the better predicting model of drug use state.Results:The resultant model included two predictors: WAIS Perceptive Organization Index and Trails Component. The prediction formula for Ln Odd Ratio of drug abuse/dependence group is: -13.83 + 1.09 (Trails Z score) + 0.16 (WAIS Perceptive Organization Index). It explains for 63% of the variance (p = 0.001). The ROC curve for using in diagnose was constructed.Conclusion:Neuropsychological diagnosis can contribute to the differential diagnosis of schizophrenia in dual pathology. The better functioning in visual-spatial tasks increases the probability of psychosis related with drugs use.

Abstract
After the implementation of universal hepatitis A virus vaccination in Argentina, the outcome of pediatric acute liver failure (PALF) remains unknown. We aimed to identify variables associated with the risk of liver transplantation (LT) or death and to determine the causes and short-term outcomes of PALF in Argentina. We retrospectively included 135 patients with PALF listed for LT between 2007 and 2016. Patients with autoimmune hepatitis (AIH), Wilson's disease (WD), or inborn errors of metabolism (IEM) were classified as PALF-chronic liver disease (CLD), and others were classified as "pure" PALF. A logistic regression model was developed to identify factors independently associated with death or need of LT and risk stratification. The most common etiologies were indeterminate (52%), AIH (23%), WD (6%), and IEM (6%). Overall, transplant-free survival was 35%, whereas 50% of the patients underwent LT and 15% died on the waiting list. The 3-month risk of LT or death was significantly higher among patients with pure PALF compared with PALF-CLD (76.5% versus 42.5%; relative risk, 1.8 [1.3-2.5]; P < 0.001), and 3 risk factors were independently associated with worse outcome: international normalized ratio (INR) ≥3.5 (odds ratio [OR], 3.1; 95% confidence interval [CI], 1.3-7.2]), bilirubin ≥17 mg/dL (OR, 4.4; 95% CI, 1.9-10.3]), and pure PALF (OR, 3.8; 95% CI, 1.6-8.9). Patients were identified by the number of risk factors: Patients with 0, 1, or ≥2 risk factors presented a 3-month risk of worse outcome of 17.6%, 36.6%, and 82%, respectively. In conclusion, although lacking external validation, this simple risk-staging model might help stratify patients with different transplant-free survival rates and may contribute to establishing the optimal timing for LT.

Abstract
Objectives The neutropenic murine thigh infection model and a dose-fractionation approach were used to determine the pharmacokinetic/pharmacodynamic (PK/PD) relationship of LYS228, a novel monobactam antibiotic with activity against Enterobacteriaceae including carbapenem-resistant strains. Methods Mice (n = 4 per group) were inoculated with Enterobacteriaceae strains via intramuscular injection. Two hours post-bacterial inoculation, treatment with LYS228 was initiated. Animals were euthanized with CO2 24 h after the start of therapy and bacterial counts (log10 cfu) per thigh were determined. PK parameters were calculated using free (f) plasma drug levels. Results Following a dose-fractionation study, non-linear regression analysis determined that the predominant PK/PD parameter associated with antibacterial efficacy of LYS228 was the percentage of the dosing interval that free drug concentrations remained above the MIC (%fT>MIC). In a dose-dependent manner, LYS228 reduced the thigh bacterial burden in models established with Enterobacteriaceae producing β-lactamase enzymes of all classes (e.g. ESBLs, NDM-1, KPC, CMY-2 and OXA-48). The range of the calculated static dose was 86-649 mg/kg/day for the isolates tested, and the magnitude of the driver of efficacy was 37-83 %fT>MIC. %fT>MIC was confirmed as the parameter predominantly driving efficacy as evidenced by a strong coefficient of determination (r2 = 0.68). Neutrophils had minimal impact on the effect of LYS228 in the murine thigh infection model. Conclusions LYS228 is efficacious in murine thigh infection models using β-lactamase-producing strains of Enterobacteriaceae, including those expressing metallo-β-lactamases, ESBLs and serine carbapenemases, with the PK/PD driver of efficacy identified as %T>MIC.

Abstract
A dry-film coliform count plate that is inoculated with 5 mL sample was compared with the Violet Red Bile Agar plate method in a collaborative study by 18 laboratories. Products analyzed were 2% milk, chocolate milk, cream, vanilla ice cream, cottage cheese, and cheese. Collaborators tested blind duplicate uninoculated samples and samples inoculated at low, medium, and high level. Significantly (P< 0.05) higher numbers of coliforms were recovered by the dry-film method from 2% milk samples at the 3 inoculum levels, the chocolate milk at the low- and high-inoculum levels, and the cream at the high-inoculum level. Significantly higher counts were obtained by the agar method for cottage cheese samples at the low-inoculum level. The repeatability standard deviation for the dry-film method was significantly higher for the high-inoculum level chocolate milk sample and the medium-inoculum level cottage cheese. The same statistic was significantly higher for the agar method at all 3 inoculum levels in the 2% milk and the medium-inoculum level cream. The high-sensitivity dry rehydratable film method for enumeration of coliforms in dairy products has been adopted first action by AOAC INTERNATIONAL.

Abstract
Aging is the major risk factor for the development of chronic diseases. After decades of research focused on extending lifespan, current efforts seek primarily to promote healthy aging. Recent advances suggest that biological processes linked to aging are more reliable than chronological age to account for an individual’s functional status, i.e. frail or robust. It is becoming increasingly apparent that biological aging may be detectable as a progressive loss of resilience much earlier than the appearance of clinical signs of frailty. In this context, the INSPIRE program was built to identify the mechanisms of accelerated aging and the early biological signs predicting frailty and pathological aging. To address this issue, we designed a cohort of outbred Swiss mice (1576 male and female mice) in which we will continuously monitor spontaneous and voluntary physical activity from 6 to 24 months of age under either normal or high fat/high sucrose diet. At different age points (6, 12, 18, 24 months), multiorgan functional phenotyping will be carried out to identify early signs of organ dysfunction and generate a large biological fluids/feces/organs biobank (100,000 samples). A comprehensive correlation between functional and biological phenotypes will be assessed to determine: 1) the early signs of biological aging and their relationship with chronological age; 2) the role of dietary and exercise interventions on accelerating or decelerating the rate of biological aging; and 3) novel targets for the promotion of healthy aging. All the functional and omics data, as well as the biobank generated in the framework of the INSPIRE cohort will be available to the aging scientific community. The present article describes the scientific background and the strategies employed for the design of the INSPIRE Mouse cohort.

Abstract
This article defines and discusses 6 beliefs, attitudes, and practices that can erode or undermine self-esteem and self confidence in student-scholars from underrepresented and marginalized groups in academic settings. Specifically, the beliefs and practices are reactions to implicit bias, color blindness, imposter syndrome, internalized racism, stereotype threat, and code-switching. Mentors need to know how to discuss these reactions because they can also influence the mentoring process and academic performance. To minimize incidents or interactions that might result in scholars not being able to find their place in these settings, recommendations for basic mentoring strategies and individual- and systemic-level approaches to address institutional racism are discussed.

Abstract
Health inequities and disparities among various racial/ethnic minority, sexual minority, and rural populations are the focus of increasing national efforts. Three health problems disproportionately affecting these populations-HIV/AIDS, substance abuse, and trauma-deserve particular attention because of their harmful effects on health across the life span. To address these problems, our training program, the UCLA HIV/AIDS, Substance Abuse, and Trauma Training Program (HA-STTP), mentors and trains early career behavioral health scientists to conduct research using scientifically sound, culturally collaborative, and population-centered approaches. HA-STTP has been highly successful in training a diverse, productive, nationwide group of scholars. The program provides 2 years of training and mentorship to 20 (5 per year over 4 years) scholars. It is unique in its attention to traumatic stress as a form of dysregulation, particularly as experienced by underserved populations. Furthermore, our training program embraces a uniquely comprehensive, culturally grounded understanding of traumatic stress and its implications for substance abuse and HIV. HA-STTP advances scholars' knowledge of the interconnections among substance abuse, HIV/AIDS, traumatic stress, and health disparities, particularly in underrepresented populations; provides intensive mentorship to support scholars' research interests and career trajectories; capitalizes on a multidisciplinary, multiracial/ethnic network of expert faculty; and evaluates the program's impact on scholars' knowledge and productivity. By fostering the growth of scholars committed to conducting research with underrepresented populations that are disproportionately affected by HIV/AIDS, substance abuse, and traumatic stress, this program enhances nationwide efforts to diminish the prevalence of these problems and improve health and quality of life.

Abstract
IntroductionThere is limited evidence favoring the use of the sentinel lymph node technique in ovarian cancer, and no standardized approach has been studied. The objective of the present pilot study is to determine the feasibility of the sentinel lymph node technique by applying a clinical algorithm.MethodsPatients with confirmed ovarian cancer were included. 99mTc and indocyanine green were injected into the ovarian and infundubulo-pelvic ligament stump. A gamma probe and near-infrared fluorescence imaging were used for sentinel lymph node detection.ResultsThe sentinel lymph node technique was performed in ten patients with a detection rate in the pelvic and/or para-aortic region of 100%. The tracer distribution rates of sentinel lymph nodes in the pelvic and para-aortic regions were 87.5% and 70%, respectively.ConclusionThe detection of sentinel lymph nodes in early-stage ovarian cancer appears to be achievable. Based on these results, a clinical trial entitled SENTOV (SENtinel lymph node Technique in OVarian cancer) will be performed.

Abstract
Wavelets are designed to have compact support in both time and frequency, giving them the ability to represent a signal in the two-dimensional time-frequency plane. The Gaussian, the Mexican hat and the Morlet wavelets are crude wavelets that can be used only in continuous decomposition. The Morlet wavelet is complex-valued and suitable for feature extraction using the continuous wavelet transform. Continuous wavelets are favoured when high temporal and spectral resolution is required at all scales. In this paper, considering the properties from the Morlet wavelet and based on the structure of a recurrent high-order neural network model, a novel wavelet neural network structure, here called a recurrent Morlet wavelet neural network, is proposed in order to achieve a better identification of the behaviour of dynamic systems. The effectiveness of our proposal is explored through the design of a decentralized neural backstepping control scheme for a quadrotor unmanned aerial vehicle. The performance of the overall neural identification and control scheme is verified via simulation and real-time results.This article is part of the theme issue 'Redundancy rules: the continuous wavelet transform comes of age'.

Abstract
SummaryVascular prostacyclin (PGI2) production is different in the arteries and veins of the dog. Experiments were performed to determine whether chronic grafting of the femoral vein into the arterial circulation would alter the normal PGI2 and thromboxane (TxA2) synthesis of the “arterialized” veins. Spontaneous and arachidonic acid (AA) stimulated PGI2 and TxA2 production (measured by radioimmunoassay of 6-keto PGF1α and TxB2 respectively) were analysed in full thickness punch biopsies of the middle part of the grafts after 3 and 16 months and compared with unoperated veins and arteries. PGI2 production was significantly higher in arteries than in veins but no significant difference in TxB2 production was found. Middle “arterialized” venous graft produced significantly lower amounts of PGI2 and higher amounts of TxB2 than unoperated vessels. PGI2 production was more reduced in the distal than in the middle or the proximal parts of the venous grafts especially when stimulated with AA. These findings do not support the concept that the venous graft was biochemically adapted or “arterialized” in terms of PGI2 production when implanted for 3 months or longer. Rather the markedly decreased PGI2/TxB2 ratio in the middle of the graft may be a contributory cause of thrombogenicity and may be implicated in the pathogenesis of neointimal hyperplasia.

Abstract
VP2/VP6 virus like particles (VLPs) are very effective in inducing protection against the rotavirus infection in animal models. Individually, VP6 can also induce protection. However, there is no information about the immunogenicity of VP2. The aim of this work was to evaluate the efficacy of DNA vaccines codifying for VP2 or VP6, alone or combined, to induce protection against the rotavirus infection. Murine rotavirus VP2 and VP6 genes were cloned into the pcDNA3 vector. Adult BALB/c mice were inoculated three times by intramuscular (i.m.) injections with 100 or 200µg of pcDNA3-VP2 or pcDNA3-VP6 alone or co-administered with 100µg of pcDNA3-VP2/100µg of pcDNA3-VP6. Two weeks after the last inoculation, mice were challenged with the wild type murine rotavirus strain epizootic diarrhea of infant mice (EDIMwt). We found that both plasmids, pcDNA3-VP2 and pcDNA3-VP6, were able to induce rotavirus-specific serum antibodies, but not intestinal rotavirus-specific IgA; only 200µg of pcDNA3-VP6 induced 35% protection against the infection. A similar level of protection was found when mice were co-administered with 100µg of pcDNA3-VP2/100µg of pcDNA3-VP6 (1:1 ratio). However, the best protection (up to 58%) occurred when mice were inoculated with 10µg of pcDNA3-VP2/100µg of pcDNA3-VP6 (1:10 ratio). These results indicate that the DNA plasmid expressing VP6 is a better vaccine candidate that the one expressing VP2. However, when co-expressed, VP2 potentiates the immunogenicity and protective efficacy of VP6.

Abstract
We conducted focus groups with defense lawyers, clinicians, and education advocates to gather their perspectives on families' experiences with the juvenile justice system. Our quantitative descriptive analysis identified a range of themes such as discussions about the poor treatment of families as well as recommendations for a shifting of power to families. These perspectives may provide insights about the context in which families are expected to participate in interventions, meet probationary demands, and provide for their youth's well-being. The results support evidence gathered from families about the impact of youth incarceration on their lives and has implications for practitioners and researchers working with families whose youth have been incarcerated.

Abstract
Hemorrhagic cystitis is generally a benign self-limited disorder, however there are some severe cases which are associated to a significant blood loss. The etiology may be either bacterial, viral or chemical in origin; though the cause is not identified in most of the cases. Immunocompromised patients or patients who have undergone chemotherapy or radiation constitute the highest risk group. There are only a few articles about hemorrhagic cystitis in pregnancy, frequently associated with preterm labor. We describe, for the first time in literature, one patient with a clinical status of hematuria in two consequent pregnancies, without any identified cause and a medical history negative for recurrent or hemorrhagic cystitis and we report an overview of literature concerning this topic.

Abstract
Intestinal dysbiosis is being evaluated as an influencing factor in human diseases. Our laboratory works on the general hypothesis that the association is bidirectional and that disease induction affects the composition of the microbiota. Non-obese diabetic (NOD) mice develop spontaneous diabetes unless active experimental autoimmune encephalomyelitis (EAE), a murine model of multiple sclerosis, is induced. It was proposed that the complete Freund’s adjuvant used for active induction of EAE protect against diabetes. Interestingly, although oral antibiotics treatment reduces EAE severity in SJL and C57BL/6 mice, others showed that the same treatment exacerbates diabetes in adult NOD mice. We questioned whether two different diseases affecting one animal strain, the NOD mice, affected the microbiota composition differently. We hypothesized that the gut microbiota differs between the acute inflammatory and chronic progressive stages that characterize the NOD EAE model. Further, we proposed differences in the microbiota/disease axis in EAE and diabetes. We observed significant changes in the microbiota of NOD mice that developed a severe secondary form of EAE when compared with healthy control mice. The genera Coprococcus, Ruminococcus, and Akkermansia were found elevated in EAE mice while undetermined members of the families Lactobacillaceae and Christensenellaceae were significantly reduced. Furthermore, we compared the EAE and diabetes microbiome and evaluated the effects of transplantation stool samples obtained from EAE, diabetes and control mice on diabetes progression. Our findings support the hypothesis that there are reciprocal effects between disease induction and the modification of the microbiome.

Abstract
<p>This study aimed to evaluate the effect of feeding dried foliage (leaves and petioles) of <em>Acacia saligna</em>, <em>Leucaena leucocephala</em> or <em>Moringa oleifera</em> on the performance, digestibility, N utilisation, caecal fermentation and microbial profiles in New Zealand White (NZW) rabbits. One hundred weaned male NZW rabbits weighing 819.2±16.6 g and aged 35±1 d were randomly allocated into 4 groups of 25 rabbits each. Rabbits were fed on pelleted diets containing 70% concentrate mixture and 30% Egyptian berseem (<em>Trifolium alexandrinum</em>) hay (Control diet) or one of the other 3 experimental diets, where 50% of berseem hay was replaced with <em>A. saligna</em> (AS), <em>L. leucocephala</em> (LL) or <em>M. oleifera</em> (MO). Compared to Control diet, decreases in dry matter (DM; <em>P</em>=0.004), organic matter (<em>P</em>=0.028), crude protein (CP; <em>P</em>=0.001), neutral detergent fibre (<em>P</em>=0.033) and acid detergent fibre (<em>P</em>=0.011) digestibility were observed with the AS diet. However, DM and CP digestibility were increased by 3% with the MO diet, and N utilisation was decreased (<em>P</em><0.05) with AS. Rabbits fed AS and LL diets showed decreased (<em>P</em>=0.001) average daily gain by 39 and 7%, respectively vs. Control. Feed conversion was similar in Control and MO rabbits, whereas rabbits fed AS diet ate up to 45% more feed (<em>P</em>=0.002) than Control rabbits to gain one kg of body weight. Caecal ammonia-N was increased (<em>P</em>=0.002) with LL, while acetic acid was decreased (<em>P</em>=0.001) with AS diet vs. other treatments. Caecal <em>E. coli</em> and <em>Lactobacillus</em> spp. bacteria counts were decreased with MO by about 44 and 51%, respectively, vs. Control. In conclusion, under the study conditions, tree foliage from <em>M. oleifera</em> and <em>L. leucocephala</em> are suitable fibrous ingredients to be included up to 150 g/kg in the diets of growing rabbits, and can safely replace 50% of berseem hay in diets of NZW rabbits without any adverse effect on their growth performance. Foliage from <em>M. oleifera </em>had a better potential as a feed for rabbits than that from <em>L. leucocephala</em>. Although foliage from <em>A. saliga </em>may be also used at 150 g/kg in the diets of growing rabbits, this level of inclusion may result in reduced feed digestibility and growth performance.</p>

Abstract
Feralisation occurs when a domestic population recolonizes the wild, escaping its previous restricted environment, and has been considered as the reverse of domestication. We have previously shown that Kauai Island's feral chickens are a highly variable and admixed population. Here we map selective sweeps in feral Kauai chickens using whole-genome sequencing. The detected sweeps were mostly unique to feralisation and distinct to those selected for during domestication. To ascribe potential phenotypic functions to these genes we utilize a laboratory-controlled equivalent to the Kauai population-an advanced intercross between Red Junglefowl and domestic layer birds that has been used previously for both QTL and expression QTL studies. Certain sweep genes exhibit significant correlations with comb mass, maternal brooding behaviour and fecundity. Our analyses indicate that adaptations to feral and domestic environments involve different genomic regions and feral chickens show some evidence of adaptation at genes associated with sexual selection and reproduction.

Abstract
Purpose/objectives The aim of this study is to analyze the results of exclusive interstitial brachytherapy (IBT) as a conservative approach in the treatment of penile cancer confined to the glans or the shaft with long-term follow-up in a single institution. Materials/methods Between July 1992 and November 2013, 73 consecutive patients with non-metastatic invasive penile cancer were treated by Low dose rate (LDR) IBT in our institution. The localization of the primary lesion was glands in 67 patients (91.8 %) and shaft in 6 patients (8.2 %). All 73 patients presented with squamous cell carcinoma with grades of differentiation as follows: 34 patients with grade 1 (44.7 %), 9 patients with grade 2 (11.8 %), 9 patients with grade 3 (11.8 %) and 21 patients unknown (28.8 %). Six patients (7.8 %) presented with in situ carcinoma, 55 patients (75,3 %) presented with T1, 11 patients (15 %) presented with T2, and one patient (1.3 %) presented with Tx. Inguinal nodal dissection was performed in 29 patients (38.2 %); 13 patients (17.8 %) presented with histologically confirmed positive ganglion. After circumcision, IBT was performed using a hypodermic needle. The median dose delivered was 60 Gy (range, 40 to 70 Gy). The median activity of the iridium-192 wire was 1.12 mCi/cm, and the median reference isodose rate was 0.4 Gy/h (range, 0.2–1.2). Patients with histological inguinal metastases received external beam radiotherapy to the selected inguinal affected area with a median dose of 45 Gy (30–55 Gy). Results The median follow-up time was 51.8 months (range 34.4 to 68.7). The 5-year overall survival was 82.0 %, with eight deaths from cancer and five non-cancer-related deaths. Disease-specific survival was 91.4 %, relapse-free survival was 64.4 %, and local relapse-free survival as 74 %. Total or partial penile preservation was 87.9 % at 5-years. Complications rates at 5 years were 6.6 % urethral stenosis (five patients), two patients (2.6 %) with pain related to sexual intercourse and four patients (5.3 %) with dysuria grade 2. Five patients (6.8 %) required penile amputation for necrosis. Conclusions IBT provides good local control with organ preservation, excellent tolerance and low complication rates in early-stage penile cancers.

Abstract
The objective of the study was to evaluate utilization of dietary minerals and trace elements in pregnant heifers with distinct residual feed intakes (RFI). Feed intake, body weight (BW), and body composition traits were recorded in 36 crossbred heifers over a period of 37 wk, starting shortly after weaning at 8.3 (0.10; standard deviation) mo of age with an average BW of 276 (7.8) kg. Both BW and body composition were monitored regularly throughout the study, whereas individual feed intake was assessed during the last 84 d of the trial. Data recorded were used to calculate RFI for each heifer. Heifers were ranked based on RFI and assigned to high (n=14) or low (n=10) RFI groups. After the RFI study, 24 selected heifers [age 18.2 (0.14) mo; 87.5 (4.74) d in gestation; 497 (8.5) kg of BW] were used in an indirect digestibility trial (lignin as internal marker). Heifers were fed a ration containing corn silage, haylage, and a mineral premix in which Ca, P, K, Na, Mg, S, Cu, Fe, Mn, Mo, Se, Zn, and Co were provided in the diet according to National Research Council requirements of pregnant replacement heifers. The digestibility trial lasted 1 wk, during which samples of feces were gathered twice daily, and blood and liver biopsy samples were collected on the last day. We noted no significant differences between low- and high-RFI heifers in dry matter digestibility. Apparent absorption of Cu, Zn, and Mn was increased in heifers with low RFI, and apparent absorption of Co tended to be greater for these animals. Concentrations of macrominerals and trace elements in serum of pregnant heifers were similar for both groups except for Se, which was increased in the serum of low-RFI heifers. Liver concentrations of Cu, Fe, Mn, Mo, Se, and Zn did not differ between low- and high-RFI heifers. In conclusion, whereas improved absorption of some trace elements (Cu, Zn, Mn, and Co) and increased Se serum concentration appear to be associated with superior feed efficiency in pregnant heifers, further studies are needed to investigate the causality of such relationships.

Abstract
Feature extraction for automatic classification of EEG signals typically relies on time frequency representations of the signal. Techniques such as cepstral-based filter banks or wavelets are popular analysis techniques in many signal processing applications including EEG classification. In this paper, we present a comparison of a variety of approaches to estimating and postprocessing features. To further aid in discrimination of periodic signals from aperiodic signals, we add a differential energy term. We evaluate our approaches on the TUH EEG Corpus, which is the largest publicly available EEG corpus and an exceedingly challenging task due to the clinical nature of the data. We demonstrate that a variant of a standard filter bank-based approach, coupled with first and second derivatives, provides a substantial reduction in the overall error rate. The combination of differential energy and derivatives produces a 24% absolute reduction in the error rate and improves our ability to discriminate between signal events and background noise. This relatively simple approach proves to be comparable to other popular feature extraction approaches such as wavelets, but is much more computationally efficient.
