Abstract
Complete replacement of inorganic trace minerals (ITM) with proteinated organic trace minerals (PTM) at equal or lower inclusion rates was evaluated. One thousand and eight, one-d-old male chicks were divided into 24 pens containing 42 chicks, and randomly allocated to one of the following: T1: control group with ITM supplied at the standard commercial level in Ecuador; T2: PTM at 100% T1; T3: PTM at 66% TI; and T4: PTM at 33% T1. The 42-d experiment employed a three-phase feeding programme (1-14, 15-28 and 29-42 d). Restricted feeding was used to prevent the development of ascites associated with high altitude. At 21 and 42 d of age, Cu, Mn and Zn retention were measured in tibial bone, and Fe in whole blood. Lymphoid organ weights were at 21 and 42 d of age. Antibody titres were measured by ELISA at 42 d of age. Weight gain, feed consumption, feed conversion and mortality were similar among treatments, although were below breed expectations due to feed restriction practices. Blood Fe was not affected by treatment (P<0.05). At both 21 and 42 d of age, minerals in tibia differed (P<0.01), with Mn and Zn concentrations being significantly higher in all PTM groups, compared to ITM control at 42 d. However, at 21 d, Zn was higher for the ITM-fed birds. No differences in lymphoid organ (bursa, thymus, and spleen) weights were observed, or for Gumboro (infectious bursal disease), infections bronchitis virus and reovirus antibody titres. For Newcastle disease virus, T4 birds had significantly lower antibody titres compared to other treatment groups. In conclusion, replacement of inorganic minerals with a proteinated form organic minerals at lower inclusion rates had no negative impact on performance, lymphoid organ weight or antibody titres in broilers raised under commercial conditions of high altitude and restricted feeding.

Abstract
Individuals’ access to sport and physical activity has been hampered due to COVID-19 lockdown restrictions. In Australia participation in community sport was cancelled during lockdowns. There is limited research on the impact of sport participation restrictions on the health and wellbeing of adults. Aim The aim of this study was to investigate the perceived health and wellbeing of a sample of predominantly active Australian adults, both during COVID-19 and in comparison with one year earlier (pre COVID-19). Methods A survey was conducted during the first COVID-19 restrictions and lockdowns in Australia in May–June 2020. It was distributed by national and state sporting organisations and through researchers’ social media accounts. This particular paper focuses on adults aged 18–59 years. The survey collected information on participant demographics, the sport and physical activity patterns pre- COVID-19, and health and wellbeing outcomes during COVID-19 lockdown and compared to one year earlier. The health measures were cross-tabulated against the demographic and sport and physical activity variables, and group profiles compared with chi-square tests. Scales were derived from three wellbeing questions, and group differences were analysed by t-tests and F-tests. Results The survey sample included 1279 men and 868 women aged 18–59 years. Most (67%) resided in metropolitan cities. The great majority (83%) were sport participants. During COVID-19 lockdown men were significantly more likely than women to report worse or much worse general (p = 0.014), physical (p = 0.015) and mental health (p = 0.038) and lower life satisfaction (p = 0.016). The inactive adults were significantly more likely to report poorer general health (p = 0.001) and physical health (p = 0.001) compared to active adults. The younger age cohort (18–29 years) were significantly more likely to report poorer general wellbeing (p < 0.001), and lower life satisfaction (p < 0.001) compared to the older age groups. Conclusion It seems that the absence of playing competitive sport and training with friends, teams and within clubs has severely impacted males and younger adults in particular. Sports clubs provide an important setting for individuals’ health and wellbeing which is why clubs require the capacity to deliver sport and individuals may need to regain the motivation to return.

Abstract
OBJECTIVES This study aimed to examine the validity and reliability of a rapid, clinically administrable loneliness screening tool for older adults called the ALONE scale. DESIGN This was a cross-sectional study. SETTING Participants were recruited from either ambulatory clinics or a nursing home. PARTICIPANTS Participants were 65 years of age or older and had SLUMS scores of 14 or greater. MEASUREMENTS Construct validity of the 5-item ALONE scale was examined through correlation with the previously validated UCLA-20 Loneliness Questionnaire. Divergent validity for discriminating between loneliness and depression was examined through correlation with the PHQ-8 items. Test-retest reliability was assessed by correlation between baseline ALONE scores and those from re-administration in 2-3 weeks. RESULTS Among ambulatory clinic participants (n=199), the ALONE scale showed strong correlation with the UCLA-20 (r=0.81, p < 0.001). Similar correlation coefficients were seen among demographic subgroups: White Americans (n=123) (r=0.81, p < 0.001), Black Americans (n=66) (r=0.79, p < 0.001), adults ≥ 75 years (n=74) (r=0.86, p < 0.001). Among nursing home patients (n=22), the ALONE scale showed fair correlation with the UCLA-20 (r=0.74, p < 0.001). Test-retest of the ALONE scale showed a strong correlation (r=0.89, p < 0.001). ROC curve analysis determined ALONE scale scores of 8 and greater as optimal for severe loneliness screening. CONCLUSION This study shows that the ALONE scale has strong validity in assessing older adults for severe loneliness. The brief, comprehensible nature of the ALONE scale reduces adoption burden making it optimal for use in clinical settings.

Abstract
Background COVID-19 has the potential to cause outbreaks in hospitals. Given the comorbid and elderly cohort of patients hospitalized, hospital-acquired COVID-19 infection is often fatal. Pathogen genome sequencing is becoming increasingly important in infection prevention and control (IPC). Aim To inform the understanding of in-hospital SARS-CoV-2 transmission in order to improve IPC practices and to inform the future development of virological testing for IPC. Methods Patients detected COVID-19 positive by polymerase chain reaction on Ward A in April and May 2020 were included with contact tracing to identify other potential cases. Genome sequencing was undertaken for a subgroup of cases. Epidemiological, genomic, and cluster analyses were performed to describe the epidemiology and to identify factors contributing to the outbreak. Findings Fourteen cases were identified on Ward A. Contact tracing identified 16 further patient cases; in addition, eight healthcare workers (HCWs) were identified as being COVID-19 positive through a round of asymptomatic testing. Genome sequencing of 16 of these cases identified viral genomes differing by two single nucleotide polymorphisms or fewer, with further cluster analysis identifying two groups of infection (a five-person group and a six-person group). Conclusion Despite the temporal relationship of cases, genome sequencing identified that not all cases shared transmission events. However, 11 samples were found to be closely related and these likely represented in-hospital transmission. This included three HCWs, thereby confirming transmission between patients and HCWs.

Abstract
Purpose The primary objective was to determine the feasibility of implementing the TrueNTH SHAReClinic as a pan-Canadian sexual health and rehabilitation intervention for patients treated for localized prostate cancer. Methods The feasibility study was designed to evaluate the accessibility and acceptability of the intervention. Participants from five institutions across Canada were enrolled to attend one pre-treatment and five follow-up online clinic visits over 1 year following their prostate cancer (PC) treatment. Results Sixty-five patients were enrolled in the intervention. Website analytics revealed that 71% completed the intervention in its entirety, including the educational modules, with an additional 10% completing more than half of the intervention. Five thousand eighty-three views of the educational modules were made along with 654 views of the health library items. Over 1500 messages were exchanged between participants and their sexual health coaches. At 12 months, the intervention received an overall average participant rating of 4.1 out of 5 on a single item satisfaction measure. Conclusion Results support the TrueNTH SHAReClinic as highly acceptable to participants as defined by intervention adherence and engagement. The TrueNTH SHAReClinic demonstrated promise for being a feasible and potentially resource-efficient approach to effectively improving the sexual well-being of patients after PC treatment.

Abstract
We present the case of a 33-year-old parturient who required caesarean delivery at 31 weeks' gestation. She had a history of degenerative disease of the lumbar spine secondary to tuberculosis, acquired as a child in India. Her complex medical history also included ischaemic heart disease and obstructive sleep apnoea, and due to this general anaesthesia was considered to be of high risk. However, regional anaesthesia also posed significant challenges because magnetic resonance imaging of the spine showed a partial collapse with subsequent fusion of second and third lumbar vertebral bodies with thoracolumbar kyphosis. Neuraxial anaesthesia was performed with ultrasound guidance for determining levels and depth of epidural space. An epidural was inserted at the T12-L1 interspace and a spinal anaesthetic block was placed at L4-L5. Delivery and recovery were uneventful. This case highlights the safe and effective use of neuraxial anaesthesia in an asymptomatic patient with treated spinal tuberculosis as well as the usefulness of high-quality imaging of the spine in the decision to perform neuraxial anaesthesia.

Abstract
1. This experiment was conducted to evaluate the effect of organic and inorganic trace minerals in diets fed to 1872, one-day-old male Ross 708 broiler chicks. Two sources of supplemental trace minerals (inorganic or organic) and four trace minerals levels (12.5%, 25.0%, 37.5% or 50.0%) plus a positive control containing inorganic minerals at 100% of recommended levels according to Brazilian industry standards, were used in the diets. 2. When analysed with mineral source as the main factor, broilers fed diets containing organic minerals had better feed conversion (FCR) throughout the trial, until 48 d of age (1.754 organic vs. 1.783 inorganic; P < 0.05), improved liveability at 48 d (95.8% organic vs. 93.6% inorganic; P < 0.05) and higher weight gain at 48 d (3.941 kg organic vs. 3.881 kg inorganic; P < 0.05) compared to the inorganic trace mineral diets. At lower dietary inclusion levels (12.5% and 25%) the organic mineral-fed birds had a four-point improvement in FCR (P < 0.05). 3. Feeding organic minerals improved tibial ash at 48 d from 49.5% to 51.25% (P < 0.05). The P and Ca in the tibia at 48 d were significantly (P < 0.05) higher for the birds fed organic minerals (Ca: 17.4% vs. 18.7%; P: 8.8% vs. 9.4%, respectively). The lower levels of trace minerals in feed reduced the mineral concentration of Zn, Cu and Mn in the faeces and, hence, in the litter (P < 0.05). 4. Feeding organic minerals promoted a small, but statistically significant, drop in pH of breast meat compared to inorganic minerals at 48 d (5.83 vs. 5.86, respectively; P < 0.05). The organic mineral diets reduced drip loss in breast meat compared to inorganic trace mineral supplementation at 32 d of age, but not in older birds (2.46% vs. 3.77%, respectively; P < 0.05). 5. Oxidation status, measured by superoxide dismutase activity in breast muscle at 48 d of age, significantly increased with mineral inclusion levels (P < 0.001), irrespective of source. 6. It was concluded that the use of organic minerals, even at low levels in the diet, is beneficial for broiler performance and reduces the excretion of minerals in litter.

Abstract
The aim of this study was to evaluate the performance of the DiaSorin Molecular PJ-CMV multiplex real-time PCR (PJ-CMV PCR) assay (DiaSorin Molecular LLC, USA) in bronchoalveolar lavage (BAL) samples compared to direct immunofluorescence assay (IFA) for the detection of Pneumocystis jirovecii and assess CMV and P. jirovecii co-infection rate in immunosuppressed patients with suspected pneumonia. A total of 125 BAL samples from immunosuppressed patients submitted for PJP-IFA were tested. Surplus samples were saved and further tested by using the PJ-CMV PCR assay. Among the 125 samples, P. jirovecii was detected in 31.2% (39/125) and in 40% (50/125) of the specimens using IFA and PJ-CMV PCR respectively. Eleven of the PJ-CMV PCR positive samples were negative by direct IFA for P. jirovecii. All samples positive by direct IFA were also positive by PJ-CMV PCR. Using the direct IFA as a gold standard, the PJ-CMV PCR sensitivity, specificity, positive predictive value and negative predictive value for detection of P. jirovecii were 100%, 87.2%, 78% and 100%, respectively. However, after reviewing the clinical diagnosis, the specificity and PPV increased to 100%. Of the 50 P. jirovecii samples positive by PJ-CMV PCR, 18 (36%) were also positive for CMV by the PJ-CMV PCR. The co-infection rate was found to be 37.5% (6/16) and 35.2% (12/34) in HIV infected and non-HIV infected patients. This study indicated that the DiaSorin Molecular PJ-CMV multiplex real-time PCR assay has higher sensitivity than direct IFA for detection of P. jirovecii and provides rapid detection of PJ and CMV infection in BAL samples.

Abstract
We report the first measurement of the neutron cross section on argon in the energy range of 100-800 MeV. The measurement was obtained with a 4.3-h exposure of the Mini-CAPTAIN detector to the WNR/LANSCE beam at LANL. The total cross section is measured from the attenuation coefficient of the neutron flux as it traverses the liquid argon volume. A set of 2631 candidate interactions is divided in bins of the neutron kinetic energy calculated from time-of-flight measurements. These interactions are reconstructed with custom-made algorithms specifically designed for the data in a time projection chamber the size of the Mini-CAPTAIN detector. The energy averaged cross section is 0.91±0.10(stat)±0.09(syst) b. A comparison of the measured cross section is made to the GEANT4 and FLUKA event generator packages, where the energy averaged cross sections in this range are 0.60 and 0.68 b, respectively.

Abstract
The Arizona Department of Health Services identified unusually high levels of influenza activity and severe complications during the 2015-2016 influenza season leading to concerns about potential increased disease severity compared with prior seasons. We estimated state-level burden and severity to compare across three seasons using multiple data sources for community-level illness, hospitalisation and death. Severity ratios were calculated as the number of hospitalisations or deaths per community case. Community influenza-like illness rates, hospitalisation rates and mortality rates in 2015-2016 were higher than the previous two seasons. However, ratios of severe disease to community illness were similar. Arizona experienced overall increased disease burden in 2015-2016, but not increased severity compared with prior seasons. Timely estimates of state-specific burden and severity are potentially feasible and may provide important information during seemingly unusual influenza seasons or pandemic situations.

Abstract
BACKGROUND After a spinal cord injury, patients have different perceptions of sexuality, sexual function, and potential for fertility. These changes can greatly impact quality of life over a lifetime. PURPOSE The purpose of this workgroup was to identify common evidence based or expert opinion themes and recommendations regarding treatment of sexuality, sexual function and fertility in the spinal cord injury population. METHODS As part of the SIU-ICUD joint consultation of Urologic Management of the Spinal Cord Injury (SCI), a workgroup and comprehensive literature search of English language manuscripts regarding fertility and sexuality in the spinal cord injury patient were formed. Articles were compiled, and recommendations in the chapter are based on group discussion and follow the Oxford Centre for Evidence-based Medicine system for levels of evidence (LOEs) and grades of recommendation (GORs). RESULTS Genital arousal, ejaculation, and orgasm are significantly impacted after spinal cord injury in both male and female SCI patients. This may have a more significant impact on potential for fertility in male spinal cord injury patients, particularly regarding ability of generate erection, semen quantity and quality. Female patients should be consulted that pregnancy is still possible after injury and a woman should expect resumption of normal reproductive function. As a result, sexual health teaching should be continued in women despite injury. Pregnancy in a SCI may cause complications such as autonomic dysreflexia, so this group should be carefully followed during pregnancy. CONCLUSIONS By understanding physiologic changes after injury, patients and care teams can work together to achieve goals and maximize sexual quality of life after the injury.

Abstract
Abstract
Overall, triple negative breast cancers (TNBCs) constitute 12% of all breast cancers, and is approximately twice more prevalent in African-American populations. Louisiana has a high proportion of African-American residents (32.5% in 2015), and thus hosts a higher population of TNBC patients. TNBCs have an aggressive phenotype that is elusive to the targeted therapeutics used to treat other breast cancer subtypes. Certain kinase families have been extensively studied as regulators of epithelial-mesenchymal transition (EMT), a process involved in the initiation of cancer metastasis. Discovery of novel kinase targets within the subset of uncharacterized kinases could provide important insight into future targeted therapies. However, current models utilized in target discovery research are limited by the inability to accurately recapitulate the complex stromal architecture and heterogenous genetic and molecular composition of breast cancer. Furthermore, immortalized cell lines are limited to a 2D environment and over time acquire mutations that may not reflect the primary tumor. Recently, our laboratory has successfully established two TNBC patient-derived xenograft (PDX) models derived from African-American patients, and generated cell lines (TU-BCx-2K1, TU-BCx-2O0) and mammospheres. One of these models, 2O0, presents tumor architecture, cellular composition, genomic (qRT-PCR) and protein (western blot) expressions that are concordant with a claudin-low subtype, which has higher rates of metastasis and recurrence. Furthermore, we show that both TNBC models metastasize to the lungs, and exhibit molecular characteristics consistent with mesenchymal phenotypes. We utilized these translational PDX models to screen a library of small molecule inhibitors that represent a variety of kinase pathways to identify novel therapeutic targets and/or pathways that are specific to TNBC subtypes. We found in a preliminary cell morphology screen using three TNBC cell lines (MDA-MB-231, BT549, MDA-MB-157), two small molecule inhibitors that increased epithelial marker (CDH1) gene expression, suppressed mesenchymal (VIM, c-FOS, SNAI1, ZEB1) expression and/or suppressed cellular motility in transwell migration assays. We observed after ex vivo treatments with our PDX tumors the two compounds increase the epithelial marker CDH1 expression, and suppress mesenchymal markers (VIM, MMP2, c-FOS, SNAI1, ZEB1) expressions. We confirm these findings in the TU-BCx-2K1 cell line. Kinase array data revealed candidate kinases responsible for the observed EMT changes in the two compounds of interest (NEK5, NEK9, NEK1 potentially affect cell motility; SRC-family kinases, TAOK2, STK10 potentially affect EMT gene changes); we plan to utilize the PDX cell lines to characterize these kinases in EMT. We aim to ultimately discover novel therapeutic targets specific to different TNBC molecular subtypes.

Abstract
INTRODUCTION Spinal Cord Injury (SCI) affects sexual response based on the level and degree of completeness of injury. By using the International Standards for the Neurologic Classification of SCI in conjunction with lumbo-sacral reflexes these effects can be predicted. The International Standards for the Assessment of Autonomic Function after SCI (ISAFSCI) document the impact of SCI on sexual responses including psychogenic and reflex arousal (erection or lubrication), orgasm, ejaculation, and sensation of menses. Responses are described based upon a 0 to 2 scale with 0 being absent, 1 altered, and 2 normal response. Additionally, the lesion is described as supraconal, conal or infraconal. CASE PRESENTATION We present 4 representative cases of the impact of SCI on sexual responses and course of treatment. Case 1 describes a complete supraconal lesion above T6 with upper motor neuron syndrome. Case 2 describes a supraconal complete lesion including the T11-L2 segment. Case 3 describes an infraconal (cauda equina) lesion with lower motor neuron syndrome. Case 4 is theoretical and describes a supraconal lesion above T6 with upper motor neuron syndrome, partial sensation in T11-L2 dermatomes, and other medical comorbidities. DISCUSSION Neurologic examination combined with reflex testing allows prediction of sexual responses after SCI. It would be useful for version 2.0 of the ISAFSCI to assist clinicians in determining the anticipated changes, whether their patients are functioning as anticipated sexually after SCI or whether other concerns also require treatment.

Abstract
OBJECTIVES Vascular complications are one of the most common causes of early kidney transplant dysfunction. Contrast enhanced ultrasound increases sensitivity to vascular changes. The aim of this study was to assess the prevalence and size of vascular abnormalities in early renal transplants using 3D CEUS and the significance of perfusion defects on renal function. METHODS Ninety-nine renal transplant patients underwent 3D CEUS after surgery to quantify perfusion defects as percentage total renal volume (TRV). Serum creatinine and estimated glomerular filtration rate (eGFR) were recorded up to 3 months post-surgery. RESULTS Twenty participants had focal perfusion defects (0.2-43%TRV). There was a meaningful difference in patients with perfusion defects in eGFR at 1 month (90% CI 2.7-19.2 mL/min/1.73 m2) and 3 months (90% CI 1.9-19.6 mL/min/1.73 m2) and creatinine at 3 months (90% CI -56 - -8 μmol/L) using a predetermined clinical threshold. Perfusion defect size correlated well with both serum creatinine and eGFR at 3 months (R = 0.80, p ≤ 0.000 and 0.58, p = 0.038). No correlation was seen prior to 3 months. CONCLUSIONS Perfusion defects in kidney transplants were more common than expected and were highly likely to reduce renal function at 1-3 months, and the size of the defect affected the degree of functional change at 3 months. KEY POINTS • Perfusion defects were more common than previously thought. • Perfusion defects could be quantified using 3D CEUS. • The presence of even small perfusion defects may affect kidney function. • Size of perfusion defects correlated with subsequent kidney function at 3 months. • Potentially useful in informing clinician expectations of kidney function post-surgery.

Abstract
STUDY QUESTION Is interleukin-1 receptor antagonist (IL-1RA) involved in the toll-like receptor 3 (TLR 3)-induced inhibition of trophoblast cells' adhesion to endometrial cells in vitro? SUMMARY ANSWER IL-1RA mediates the TLR 3-induced inhibition of trophoblast cells' adhesion to endometrial cells in vitro. WHAT IS KNOWN ALREADY It is well documented that endometrial TLR 3 activation leads to impairment of trophoblast binding to endometrial cells in vitro. IL-1RA is known as an anti-implantation factor, as its injection significantly reduced implantation rates in mice by an effect on endometrial receptivity. STUDY DESIGN, SIZE, DURATION Poly I:C was used as a TLR3 specific ligand and endometrial cells were either treated or not with Poly I:C (treated versus control) in vitro. IL-1RA was applied to block IL-1 signal transduction. IL-1RA was knocked down by Accell Human IL1RN siRNA. Flagellin was used to stimulate TLR 5. SP600125 (JNK) was applied to inhibit the mitogen-activated protein kinases (MAPK) pathway. BAY11 -7082 was used to inhibit the nuclear factor-κB (NF-κB) pathway. The experiments were performed in three replicates on three separate days. PARTICIPANTS/MATERIALS, SETTING, METHODS An in vitro assay was developed using RL95-2 (an endometrial cell line) and JAr (a trophoblast cell line) cells. Initially, the production of IL-1RA in RL95-2 cells in response to TLR 3 activation was measured. To determine whether the TLR 3-induced inhibition of trophoblast binding was mediated through IL-1RA: (i) we evaluated the effect of IL-1RA on the attachment of trophoblast cells to endometrial cells; (ii) we knocked down TLR3-induced IL-1RA gene expression by IL-1RA Small interfering RNA (siRNA) and evaluated trophoblast attachment to endometrial cells. Finally, to clarify through which pathway TLR 3-induced inhibition of trophoblast binding occurs: (i) activation of NF-κB and MAPK was detected by transfecting the cells with secreted placental alkaline phosphatase reporter plasmids bearing promoter sequences for each transcription factor; (ii) the inhibitors for NF-κB and MAPK were used to block signaling; (iii) it was then investigated whether addition of these inhibitors could restore the TLR 3-induced impairment of trophoblast attachment to the endometrial cells. MAIN RESULTS AND THE ROLE OF CHANCE Our results showed that addition of polyinosinic:polycytidylic acid (Poly I:C) to RL95-2 cells significantly increased the production of IL-1RA (P < 0.05). Addition of human recombinant IL-1RA to RL95-2 cells remarkably decreased the adhesion rate of trophoblast cells to endometrial cells (P < 0.05). In addition, suppression of TLR3-induced IL-1RA gene expression in RL95-2 cells significantly restored trophoblast cells attachment to endometrial cells in the presence of Poly I:C (P < 0.05). Only TLR3 and not TLR5 induced MAPK activation (P < 0.05). TLR3 ligation did not affect NF-κB activation. Of NF-kB and MAPK inhibitors, only MAPK's inhibitor could achieve restoration of spheroid adhesion to endometrial cells (P < 0.05). LIMITATIONS, REASONS FOR CAUTION This study has been only done in vitro. Future in vivo studies will confirm our data. WIDER IMPLICATIONS OF THE FINDINGS The findings of this study have a potential clinical application in introducing IL-1RA as one of the diagnostic infertility markers in the endometrium, which can affect the process of embryo adhesion at the time of implantation. Moreover, based on the novel data obtained in the current study, blocking and regulating the MAPK pathway by its inhibitors can be used as a new strategy to prevent and treat virus-induced infertility cases in ART techniques. STUDY FUNDING/COMPETING INTEREST This study was partially funded by a Marie Curie IIF-253948 grant to I.C. and was partially funded by the author's institutions. The authors have no conflict of interest to declare.

Abstract
The developmental trajectory of language lateralisation over the preschool years is unclear. We explored the relationship between lateralisation of cerebral blood flow velocity response to object naming and cognitive performance in children aged 1-5 years. Functional transcranial Doppler ultrasound was used to record blood flow velocity bilaterally from middle cerebral arteries during a naming task in 58 children (59% male). At group level, the Lateralisation Index (LI) revealed a greater relative increase in cerebral blood flow velocity within the left as compared to right middle cerebral artery. After controlling for maternal IQ, left-lateralised children displayed lower expressive language scores compared to right- and bi-lateralised children, and reduced variability in LI. Supporting this, greater variability in lateralised response, rather than mean response, was indicative of greater expressive language ability. Findings suggest that a delayed establishment of language specialisation is associated with better language ability in the preschool years.

Abstract
STUDY QUESTION Does activation of endometrial Toll-like receptor 3 (TLR 3) affect cell receptivity to trophoblast adhesion? SUMMARY ANSWER TLR 3 activation in vitro reduces the attachment of trophoblast cells to endometrial cells by altering the cell cytoskeleton and reducing the expression of adhesion molecules in human endometrial cells. WHAT IS KNOWN ALREADY It is well documented that the presence of an infection at the time of implantation can lead to implantation failure. The female reproductive tract recognizes invading micro-organisms through the innate pathogen recognition receptors such as the TLRs. STUDY DESIGN, SIZE, DURATION Poly I:C was used as a TLR 3-specific ligand and endometrial cells were either treated or not with Poly I:C (treated versus control) in vitro. The experiments were performed in three replicates on three separate days. PARTICIPANTS/MATERIALS, SETTING, METHODS An in vitro assay was developed using RL95-2 (a human endometrial cell line) and JAr (a human trophoblast cell line) cells. Initially, the percentage of attached JAr spheroids to RL95-2 was measured in response to TLR 3 activation. Next, actin polymerization in RL95-2 cells was assessed in response to TLR 2/6, 3 and 5 activation. Phalloidin was used to assess the mean fluorescence intensity of F-actin by flow cytometry or confocal microscopy. Secondly, the influence of TLR 2/6, 3 and 5 activation on the expression of cluster of differentiation 98 (CD98) and β3 integrin was determined. To further understand through which pathways the TLR 3-induced alterations occur, inhibitors were applied for Toll/interleukin-1 receptor domain-containing adaptor inducing interferon-beta (TRIF), myeloid differentiation primary response 88 (MYD88), mitogen-activated protein kinases (MAPK) and nuclear factor pathways. MAIN RESULTS AND THE ROLE OF CHANCE We observed that stimulation of TLR 3 in endometrial cells with different concentrations of Poly I:C led to a reduction in the percentage of trophoblasts attached to the endometrial cells in a dose-dependent manner (P < 0.05). This decrease was consistent in the Poly I:C treated group regardless of the co-incubation time (P < 0.05). In addition, our results demonstrated that actin polymerization and CD98 expression significantly decreased only in response to TLR 3 activation (P < 0.05). Activation of endometrial cells with TLR 2/6, 3 and 5 significantly reduced β3 integrin expression (P < 0.05). These alterations were shown to work via MYD88-MAPK pathways (P < 0.05). LIMITATIONS, REASONS FOR CAUTION This study has been performed in vitro. Future in vivo studies will be required in order to confirm our data. WIDER IMPLICATIONS OF THE FINDINGS This is a novel discovery which extends our current knowledge concerning diagnosis and treatment of viral-induced infertility cases.

Abstract
BACKGROUND AND AIMS Erythropoietin (EPO) stimulates erythropoiesis through its specific receptor (EPO-R). Preclinical work has assigned a role for the EPO/EPO-R system in the heart and blood vessels. The potential use of erythropoiesis-stimulating agents (ESAs) for nonhematopoietic indications is a focus of current research. This article considers proven actions of EPO in the cardiovascular system, with emphasis on the human responses. DATA SYNTHESIS By use of specific anti-EPO-R antibody no EPO-R protein was detected by Western blotting in normal non-erythroid tissues. Clinical trials failed to demonstrate clear beneficial effects of high-dosed ESAs in patients with coronary syndrome or myocardial infarct. While ESA therapy may lead to an elevation in arterial blood pressure in previously anemic patients, several studies have reported no effects on vessels/blood pressure with ESAs. EPO has been reported to stimulate angiogenesis. EPO-R mRNA is detectable in human vascular endothelium. However, in most vitro studies very high concentrations of EPO were applied and well-designed studies have failed to show direct effects of ESAs on endothelial cells. Whether EPO promotes the mobilization of myeloid progenitor cells into the blood stream still needs to be studied in more detail, as this effect may prove useful for augmenting the neovascularization of ischemic tissues. With respect to the administration of ESAs to tumor patients, a deeper insight into the role of EPO for tumor angiogenesis is desirable. CONCLUSIONS The enthusiastic reports of the nonhematopoietic cytoprotective potential of EPO and its derivatives in the cardiovascular system have not yet been confirmed in placebo-controlled clinical trials.

Abstract
BACKGROUND The WHO Executive Board revised the guidance that governs the procedures for the WHO review of psychoactive substances for international drug control in 2010. To meet the standards defined in these guidelines, the current evaluation methodology at WHO must be an evidence-based assessment. METHODS We describe the history of substance evaluation from 1912 to the present and the development of the evaluation methods over time including a description of the current assessment system, using reports from WHO and its predecessor, the League of Nations. Furthermore, we describe the current review system. RESULTS We found that some substances under international control were never reviewed; other substances were reviewed decades ago. CONCLUSIONS We argue that assessments do not have unlimited validity, and therefore, substances need to be re-assessed periodically, as already recommended by the Expert Committee on Drug Dependence in 1982. We propose that the evaluation time be shortened; that the influence of the route of administration and/or dosage form of the preparation is considered in the evaluation; and we recommend studying national and regional assessment systems and adopting their best practices. With this article, we make a case for the inclusion of systematic review and other methods of comprehensive analysis of substance evaluation to arrive at a process of equal rigour and quality as already applied by WHO for the development of treatment guidelines.

Abstract
BACKGROUND Elevated body mass index (BMI) and waist circumference (WC) are associated with increased mortality risk, but it is unclear which anthropometric measurement most highly relates to mortality. We examined single and combined associations between BMI, WC, waist-hip ratio (WHR) and all-cause, cardiovascular disease (CVD) and cancer mortality. METHODS We used Cox proportional hazard regression models to estimate relative risks of all-cause, CVD and cancer mortality in 8061 adults (aged 18-74 years) in the Canadian Heart Health Follow-Up Study (1986-2004). Models controlled for age, sex, exam year, smoking, alcohol use and education. RESULTS There were 887 deaths over a mean 13 (SD 3.1) years follow-up. Increased risk of death from all-causes, CVD and cancer were associated with elevated BMI, WC and WHR (P<0.05). Risk of death was consistently higher from elevated WC versus BMI or WHR. Ascending tertiles of each anthropometric measure predicted increased CVD mortality risk. In contrast, all-cause mortality risk was only predicted by ascending WC and WHR tertiles and cancer mortality risk by ascending WC tertiles. Higher risk of all-cause death was associated with WC in overweight and obese adults and with WHR in obese adults. Compared with non-obese adults with a low WC, adults with high WC had higher all-cause mortality risk regardless of BMI status. CONCLUSION [corrected] BMI and WC predicted higher all-cause and cause-specific mortality, and WC predicted the highest risk for death overall and among overweight and obese adults. Elevated WC has clinical significance in predicting mortality risk beyond BMI.
