Modern Day Slavery in Our Own Backyard
Trafficking in persons is one of the fastest growing areas of international criminal activity. Each year an estimated 600,000 – 800,000 human beings are bought, sold or forced across the world’s borders. Approximately 2.5 million men, women and children are victims of trafficking at any point in time throughout the world. Approximately 14,500 – 17,500 individuals are trafficked annually into the United States, making the United States the third largest destination country in the world for victims of human trafficking.
In order to fight trafficking in the United States effectively, legislation at the state level, in addition to the federal anti-trafficking laws, is critical. Although many states have laws addressing kidnapping and prostitution and many state constitutions and laws address the issue of slavery, it is important that each state have legislation specifically addressing human trafficking. Thirteen states have already enacted anti-trafficking legislation and thirteen states have pending legislation. Thus, more than half of the states have taken action or are taking action in this area since the State of Washington became the first state to enact legislation in 2003. Many more states have acknowledged the need for legislation at the state level. Once the legislation is in place, the focus must be on education and training of law enforcement, non-governmental agencies, and the public, and on the facilitation of collaboration across agencies
DIAGNOSTIC ACCURACY OF IXIP INDEX AND PROSTATE MRI IN THE DIAGNOSIS OF PROSTATE CANCER: PRELIMINARY RESULTS ON A COMBINED APPROACH
The purpose of this study was to assess whether Immune CompleX Predictive Index (iXip) improves diagnostic accuracy of multiparametric prostate MRI (mpMRI) for clinically significant prostate cancer. This study included 72 patients (mean age: 68±8 years) with suspicion of prostate cancer and available iXip score. mpMRI images were evaluated by two radiologists according to the PI-RADS v2.1. Reference standard was based on fusion biopsy and standard transperineal 12-point biopsy. Diagnostic accuracy of iXip, mpMRI and their combination were calculated. Optimal cutoff of iXip with sensitivity and specificity was identified using the Youden index. Patients with clinically significant prostate cancers had significantly higher iXip values compared to patients without clinically significant prostate cancers (median 0.411 vs 0.273; p=0.026). The AUROC for iXip was 0.795 (95% CI 0.579-1.000, p=0.026). Sensitivity and specificity were 75% and 100% respectively for mpMRI alone, and 100% and 80% respectively for mpMRI combined with iXip > 0.375. The combination of mpMRI with a cutoff value of iXip > 0.375 has a very high sensitivity for the diagnosis of prostate cancer and a moderately high specificity
Radiomics and prostate MRI: Current role and future applications
Multiparametric prostate magnetic resonance imaging (mpMRI) is widely used as a triage test for men at a risk of prostate cancer. However, the traditional role of mpMRI was confined to prostate cancer staging. Radiomics is the quantitative extraction and analysis of minable data from medical images; it is emerging as a promising tool to detect and categorize prostate lesions. In this paper we review the role of radiomics applied to prostate mpMRI in detection and localization of prostate cancer, prediction of Gleason score and PI-RADS classification, prediction of extracapsular extension and of biochemical recurrence. We also provide a future perspective of artificial intelligence (machine learning and deep learning) applied to the field of prostate cancer
The synthesis of quinolone natural products from pseudonocardia sp.
Abstract The synthesis of four quinolone natural products from the actinomycete Pseudonocardia sp. is reported. The key step involved a sp2–sp3 Suzuki–Miyaura reaction between a common boronic ester lateral chain and various functionalised quinolone cores. The quinolones slowed growth of E. coli and S. aureus by inducing extended lag phases.The research leading to these results has received funding from the European Reserach Council under the European Union’s Seventh Framework Programme (FP7/2007-2013) ERC grant agreement no [279337/DOS].

Use of biochar as filler for biocomposite blown films: Structure-processing-properties relationships
In this work, biocomposite blown films based on poly(butylene adipate-co-terephthalate) (PBAT) as biopolymeric matrix and biochar (BC) as filler were successfully fabricated. The materials were subjected to a film-blowing process after being compounded in a twin-screw extruder. The preliminary investigations conducted on melt-mixed PBAT/BC composites allowed PBAT/BC 5% and PBAT/BC 10% to be identified as the most appropriate formulations to be processed via film blowing. The blown films exhibited mechanical performances adequate for possible application as film for packaging, agricultural, and compost bags. The addition of BC led to an improvement of the elastic modulus, still maintaining high values of deformation. Water contact angle measurements revealed an increase in the hydrophobic behavior of the biocomposite films compared to PBAT. Additionally, accelerated degradative tests monitored by tensile tests and spectroscopic analysis revealed that the filler induced a photo-oxidative resistance on PBAT by delaying the degradation phenomena
Malignancy course of pituitary adenoma in MEN1 syndrome: Clinical-Neuroradiological signs
Pituitary carcinomas (PCa) are extremely rare, indistinguishable from pituitary adenomas on histopathological grounds and have a poor prognosis. Most PCa start as PRL or ACTH secreting tumors in males, with relapsing invasive behaviour, refractoriness to medical and radiotherapy and increasing hormonal levels. The presence of distant metastases is still required for the diagnosis of PCa. The association with genetic endocrine diseases must be taken into account, since it adds further risk of evolution towards malignancy. Intradural spinal metastases have also been reported, so a complete craniospinal MR evaluation is recommended, when clinically indicated. We report a case of PCa, associated with MEN1 syndrome, with evidence of meningeal spread to the tentorium cerebelli, clival dura and spinal drop metastases mimicking spinal nerves schwannomas
ANATOMICAL DISSECTION AND ANALYSIS OF THE STRUCTURES OF THE UPPER LIMB
In 2015, a whole body dissection course was proposed by the University of Palermo, Palermo, Italy, thanks to the cooperation with the University of Malta, Msida, Malta. The purpose of this study was to show the the difference between the studyof anatomy on books and on corpses. The article focuses its attention on the dissection method of the upper limb. The astudy was performed on two corpses, a male and a female, by using a basic surgeon kit. Blunt dissection method was used for fasciae, innards and to isolate vascular-nervous structures from the fat; we used scalped for cutis, sub cutis, muscles, fasciae, veins, arteries and nerves of the upper limb from the shoulder to the hand. The upper limb dissection shows the difference between how a real body appears and shows the difference between how a real body appears and how books represent it
Reticulocytes in untreated Obstructive Sleep Apnoea
Background and Aim. The short, repetitive hypoxaemic episodes observed in obstructive sleep apnoea (OSA) may determine small augmentations in mature red blood cells. It is unknown whether they affect reticulocyte release. This study explored whether the number and degree of maturation of circulating reticulocytes may be altered in OSA, possibly through the effect of erythropoietin. Methods. Fifty male adult patients with suspected OSA, normoxic during wakefulness, were studied. After nocturnal polysomnography, a blood sample was withdrawn for blood cells count, erythropoietin, iron and transferrin determination. Reticulocyte concentration and degree of immaturity [high (H), medium (M), or low (L)] were also determined. Immature reticulocyte fraction (IRF) was calculated as (M+H) percentage of reticulocytes. Results. A wide range of OSA severity was found [apnoea/ hypopnoea index (AHI): 44.3±30.4, range 0.3-105; sleep time spent at oxyhaemoglobin saturation 2% had higher EPO levels (p<0.05), but not worse nocturnal desaturations, than those with values <2%. By contrast, subjects with IRF <15% showed worse desaturations (p<0.05), but similar EPO concentrations, when compared to subjects whose IRF was <10%. At univariate analysis, reticulocyte count correlated to erythropoietin, while IRF to transferrin saturation, BMI and OSA severity. At multiple regression, only lowest nocturnal oxygen saturation remained a significant contributor to IRF (r2 0.223, p<0.05). Conclusions. This data suggests that hypoxaemia due to OSA could influence the release of immature reticulocytes, but this effect is not mediated by erythropoietin
A new Ultraluminous X-ray source in the galaxy NGC 5907
We report on the serendipitous discovery of a new transient in NGC 5907, at a
peak luminosity of 6.4x10^{39} erg/s. The source was undetected in previous
2012 Chandra observations with a 3 sigma upper limit on the luminosity of
1.5x10^{38} erg/s, implying a flux increase of a factor of >35. We analyzed
three recent 60ks/50ks Chandra and 50ks XMM-Newton observations, as well as all
the available Swift observations performed between August 2017/March 2018.
Until the first half of October 2017, Swift observations do not show any
emission from the source. The transient entered the ULX regime in less than two
weeks and its outburst was still on-going at the end of February 2018. The
0.3-10 keV spectrum is consistent with a single multicolour blackbody disc
(kT~1.5 keV). The source might be a ~30 solar mass black hole accreting at the
Eddington limit. However, although we did not find evidence of pulsations, we
cannot rule-out the possibility that this ULX hosts an accreting neutron star.Comment: Accepted on MNRAS, 5 pages, 2 figure, 1 tabl
