Abstract
About 3 billion new tires are produced each year and about 800 million tires become waste annually. Global dependence upon tires produced from natural rubber and petroleum-based compounds represents a persistent and complex environmental problem with only partial and often-times, ineffective solutions. Tire emissions may be in the form of whole tires, tire particles, and chemical compounds, each of which is transported through various atmospheric, terrestrial, and aquatic routes in the natural and built environments. Production and use of tires generates multiple heavy metals, plastics, PAH's, and other compounds that can be toxic alone or as chemical cocktails. Used tires require storage space, are energy intensive to recycle, and generally have few post-wear uses that are not also potential sources of pollutants (e.g., crumb rubber, pavements, burning). Tire particles emitted during use are a major component of microplastics in urban runoff and a source of unique and highly potent toxic substances. Thus, tires represent a ubiquitous and complex pollutant that requires a comprehensive examination to develop effective management and remediation. We approach the issue of tire pollution holistically by examining the life cycle of tires across production, emissions, recycling, and disposal. In this paper, we synthesize recent research and data about the environmental and human health risks associated with the production, use, and disposal of tires and discuss gaps in our knowledge about fate and transport, as well as the toxicology of tire particles and chemical leachates. We examine potential management and remediation approaches for addressing exposure risks across the life cycle of tires. We consider tires as pollutants across three levels: tires in their whole state, as particulates, and as a mixture of chemical cocktails. Finally, we discuss information gaps in our understanding of tires as a pollutant and outline key questions to improve our knowledge and ability to manage and remediate tire pollution.

Abstract
Research in the United States evaluating ecotoxic risk to receiving waters posed by contaminants occurring in wastewater discharges typically has focused on measurements of pharmaceuticals and personal care products (PPCPs), with limited evaluations of UV filters and phenylpyrazole and neonicotinoid pesticides. In this study, concentrations of 5 representative pharmaceuticals, 11 pesticides or pesticide degradation products, and 5 ultraviolet filters were measured in 24 h composite samples of six wastewater discharges representing ∼70% of the total wastewater discharged to San Francisco Bay during the summer and fall of 2021. No significant difference was observed between concentrations measured on weekdays vs. weekends. A hydrodynamic model of San Francisco Bay was used to estimate annual average dilution factors associated with different subembayments. With and without considering dilution effects, Risk Quotients were calculated using the 90th percentile of measured concentrations in wastewater effluents and threshold concentrations associated with ecotoxicity. Risk Quotients were highest for the neonicotinoid pesticide, imidacloprid, and exceeded ecotoxicity thresholds in the lower South Bay by a factor of 2.4, even when considering dilution. Compared to commonly measured pharmaceuticals, Risk Quotients for imidacloprid were higher than those for carbamazepine, trimethoprim and diclofenac, and comparable to those for propranolol and metoprolol. Risk Quotients for the pesticide, fipronil, and the UV filter, oxybenzone, were higher than for carbamazepine. The results highlight the need to incorporate pesticides and UV filters with high Risk Quotients into studies in the United States evaluating ecotoxic risk associated with contaminants in municipal wastewater discharges.

Abstract
Introduction Hospitalized patients with COVID-19 are at increased risk of venous and arterial thrombosis, ARDS, and death. The optimal dosage of thromboprophylaxis in patients is unknown. Objective To evaluate the efficacy and safety of tinzaparin in prophylactic, intermediate and therapeutic doses in non-critical patients admitted for COVID-19 pneumonia. Design, Setting, and Participants: The PROTHROMCOVID multicenter randomized clinical trial enrolled noncritical hospitalized adult patients with COVID-19 pneumonia from February 1, 2021, to September 30, 2021, at 18 centers in Spain. Methods Patients were randomized to prophylactic tinzaparin 4500IU or intermediate dose 100IU/kg or therapeutic tinzaparin 175IU/kg during hospitalization, followed by 7 days of prophylactic tinzaparin at discharge. The patients were stratified at the time of randomization according to age, sex and the presence or absence of hypertension.The primary efficacy outcome was a composite endpoint of symptomatic systemic thrombotic events, need for invasive or non invasive mechanical ventilation or not, including high-flow nasal cannula oxygen, or death within 30 days. The main safety outcome was major bleeding at 30 days. Data were collected and adjudicated locally by non-blinded investigators through imaging, laboratory, and health record data. Results Of 311 patients randomized, 300 were included in the analysis (mean [SD]age, 56.7 [14.6] years; men, 182 [60.7%]; women, 118 [39.3%]). 106 patients (35.33%) were assigned to the prophylaxis group, 91 patients (30.33%) were allocated to the intermediate dose group and 103 patients (34.33%) were randomized to the anticoagulant dose group. The composite endpoint thrombotic event, need for invasive (IMV) or noninvasive mechanical ventilation (NIV) or HFT via nasal cannula or death at 30 days from randomization occurred in 58 patients (19.3%) of the whole population, 19 patients (17.09%) in prophylactic group, 20 (21.98%) in intermediate group and 19 (18.45%) in therapeutic group (P=0.72). No major bleeding were reported in the trial and non-major bleeding occurred in 5 patients (4.71%) in prophilactic, in 3 patients (3.2%) in intermediate arm and in 3 patients (2.9%) in therapeutic, without significant differences in each group (P=0.31). Conclusions In non-critically ill patients with COVID 19, intermediate or full-dose of tinzaparin do not appear to offer benefit over standard prophylactic doses IU in the likelihood of thrombotic event, non-invasive ventilation or high-flow oxygen, or death.

Abstract
Abstract
Study question
Can we predict if or when ovarian activation resumption occurs after Drug-Free in vitro Activation (IVA) in primary ovarian insufficiency (POI) patients?
Summary answer
Duration of amenorrhea alone could predict if ovarian activity resumption occurs. Regarding to when: as early as 21 days until 330 days after surgery.
What is known already
Primary ovarian insufficiency occurs before age 40, leading patients to infertility. Although there are a few remaining follicles, their only chance to achieve pregnancy is through egg donation. Recently, studies have been focusing on the determinants and intracellular signaling pathways involved in the activation of primordial follicles, as the maintenance of a correct ovarian reserve. A new surgical technique known as Drug-Free IVA would activate ovarian function by mechanical fragmentation. For selected patients whose ovaries still contain residual secondary follicles, the fragmentation step alone, which implies a Hippo signaling pathway disruption, would be sufficient to promote follicle growth.
Study design, size, duration
Our study is a prospective observational cohort of patients recruited in a tertiary-care university hospital approved by the Ethics Research Committee from Hospital Clinic of Barcelona (HCB/2017/0856). The diagnostic criteria of POI followed the European Society of Human Reproduction and Embryology (ESHRE) Guideline from 2016. All patients provided written informed consent.Thirty-two women included in our study underwent Drug-Free IVA by laparoscopy between January 2018 and December 2019. After surgery, a year-long follow-up was carried out.
Participants/materials, setting, methods
All patients were younger than 40 years of age; presented oligomenorrhoea or amenorrhea for at least 4 months; and FSH level greater than 25 IU/mL . We also restrict inclusion criteria to low estradiol serum levels (<20 pg/ml) absence of antral follicles in transvaginal ultrasound; and anti-Müllerian hormone (AMH) levels less than 0.10 ng/mL. Regardless of the time from POI diagnosis, all patients had duration of amenorrhea greater than 1 year.
Main results and the role of chance
As for prediction of ovarian activation, duration of amenorrhea was the only factor that could significantly differentiate patients' response to Drug-Free IVA. Since a shorter time of amenorrhea (less than 2 years) was related with ovarian activation during a year follow-up. No differences were found in age at Drug-free IVA, age of menarche, baseline FSH or AMH levels; nor presence of follicles in ovarian tissue biopsy. Regarding to time to response, in 12 patients ovarian activation occurred in the first 6 months after surgery with a total of 5 pregnancies achieved (22.7%)- resulting in 4 heathy live births and, unfortunately, one miscarriage. The other 10 patients showed ovarian activation resumption once the 180 days passed, resulting in 3 pregnancies (pregnancy rate of 30%): 2 healthy live births and one neonatal death due to extreme prematurity. An important concept here is that activation before 6 months after surgery could mean an effect on primary and/or secondary follicles, while beyond 6 months the effect might occurred on primordial follicles. Sugesting that maybe the disruption of the Hippo pathway would not only be able to act in the activation of the secondary follicles but also act in the earlier phases of the folliculogenesis.
Limitations, reasons for caution
The lack of a control group is the main limitation of our study because it would be interesting to seek for the placebo effect or intensive medical attention/care consequences in those patients, whose reported pregnancy rate is as low as 4% in observational studies.
Wider implications of the findings
Our findings define the clinical profile of patients with POI in which Drug-Free IVA would be more effective and report late ovarian follicular resumption. Meaning that disruption of the Hippo signaling pathway by ovarian fragmentation could be capable of acting in the initial phases of folliculogenesis prior to secondary follicles.

Abstract
The prototypical tasks for assessing visuospatial memory in infancy are based on the search for a hidden object in two locations. Fewer studies include more locations, delayed responses nor changes in the object's position. Our aim was to assess the visuospatial short-term and working memory in 12, 15, 18 and 22-month-old children (N = 65). Assessment included our experimental task, a working memory task and a cognitive developmental scale. Short-term and working memory abilities increased markedly at 22 months compared to younger ages and the performance of the children in our experimental task is related to other tasks previously used.

Abstract
Preterm infants have a higher risk of showing visuospatial memory impairment, the function that allows to encode and remember visual and spatial information. It has been studied in late childhood in preterm children. Studies on visuospatial memory throughout the first 2 years of life are still scarce. Behavior, temperament, and overall cognition could be altered in preterm children affecting memory performance. Therefore, the main aim of this study was to evaluate short-term and visuospatial working memory performance in a preterm sample followed longitudinally at 12, 15, 18, and 22 months (N = 15), and compare their performance with that of full-term children (N = 65). The secondary aim was to analyze the course of mnesic development in preterm infants and relate their memory performance to other cognitive abilities and behavioral tendencies. Assessment included previously published tasks and an experimental paradigm. Results showed that preterm children scored lower than full-term children on visuospatial short-term and working memory at 12 and 22 months of age, although these results varied depending on the memory test used. Preterm children's memory results showed that these skills improve in this population between the first and second year of life. Finally, memory performance was directly associated with the level of cognitive development and the presence of proactive behaviors, while being inversely correlated with the presence of disruptive behaviors and a difficult temperamental style. These preliminary findings suggest that it is possible to detect visuospatial memory difficulties in the preterm population before the age of two.

Abstract
Abstract
Introduction
Home sleep apnea testing (HSAT) has largely supplanted diagnostic polysomnography. Primary care (PC) driven HSAT utilization is common especially in rural settings that lack sleep specialist (SS) support. There have been no studies comparing appropriateness of HSAT utilization in veterans managed by SS vs. PC.
Methods
We use hub and spoke model to manage patients with OSA. SS selects testing for hub and PC utilizes HSAT for spoke patients. Testing is interpreted by SS. Patients referred for HSAT using WatchPAT over 4 months were compared on test failure rate, adherence to AASM guidelines for OSA diagnosis, adherence to HSAT use criteria, and diagnostic success rate (AHI ≥5) in high risk patients (STOPBANG ≥5) without significant comorbidities or HSAT contraindications compared to all comers.
Results
There were 125 hub and 170 spoke patients included in the analyses. Baseline characteristics were similar between sites (gender, age, BMI, Epworth sleepiness scale, neck size, STOPBANG, pacemaker dependence, and medication use affecting HSAT). Spoke patients had slightly higher prevalence of comorbidities (hypertension, cardiac arrhythmia, heart failure, COPD, stroke, and long acting opioid use). Complete HSAT failure (no data) was 2% and technical failure (monitoring time <4 hours) was 13% at both sites. Unnecessary studies primarily to confirm OSA in those previously diagnosed on therapy seeking to establish care were 3% (hub) and 21% (spoke). HSAT done in patients without significant comorbidities was 77% (hub) and 68% (spoke). Adherence to HSAT use criteria was 74% at both sites. Diagnostic success rate of prespecified and all comers was 65% vs. 60% at hub and 86% vs. 64% at spoke sites.
Conclusion
Adherence to AASM guidelines and HSAT use criteria was overall fair with low failure rates. Further improving HSAT protocol for SS and PC with the aim to improve diagnostic success rate and minimize unnecessary studies should be pursued.

Abstract
To reduce the amount of conducting additives generally required for polynitroxide-based electrodes, a stable radical (TEMPO) is combined with a conductive copolymer backbone consisting of 2,7-bisthiophene carbazole (2,7-BTC), which is characterized by a high intrinsic electronic conductivity. This work deals with the synthesis of this new polymer functionalized by a redox nitroxide. Fine structural characterization using electron paramagnetic resonance (EPR) techniques established that: 1) the nitroxide radicals are properly attached to the radical chain (continuous wave EPR) and 2) the polymer chain has very rigid conformations leading to a set of well-defined distances between first neighboring pairs of nitroxides (pulsed EPR). The redox group combined with the electroactive polymer showed not only a very high electrochemical reversibility but also a perfect match of redox potentials between the de-/doping reaction of the bisthiophene carbazole backbone and the redox activity of the nitroxide radical. This new organic electrode shows a stable capacity (about 60 mAh g-1 ) and enables a strong reduction in the amount of carbon additive due to the conducting-polymer skeleton.

Abstract
INTRODUCTION Leisure activities impact brain aging and may be prevention targets. We characterized how physical and cognitive activities relate to brain health for the first time in autosomal dominant frontotemporal lobar degeneration (FTLD). METHODS A total of 105 mutation carriers (C9orf72/MAPT/GRN) and 69 non-carriers reported current physical and cognitive activities at baseline, and completed longitudinal neurobehavioral assessments and brain magnetic resonance imaging (MRI) scans. RESULTS Greater physical and cognitive activities were each associated with an estimated >55% slower clinical decline per year among dominant gene carriers. There was also an interaction between leisure activities and frontotemporal atrophy on cognition in mutation carriers. High-activity carriers with frontotemporal atrophy (-1 standard deviation/year) demonstrated >two-fold better cognitive performances per year compared to their less active peers with comparable atrophy rates. DISCUSSION Active lifestyles were associated with less functional decline and moderated brain-to-behavior relationships longitudinally. More active carriers "outperformed" brain volume, commensurate with a cognitive reserve hypothesis. Lifestyle may confer clinical resilience, even in autosomal dominant FTLD.

Abstract
Although normal aging has been related to several cognitive difficulties, other processes have been studied less, such as spatial memory. Our aim was to compare egocentric and allocentric memory in an elderly population using ecological tasks. Twenty-eight cognitively unimpaired participants performed Egocentric and Allocentric Spatial Memory Tasks, as well as Spatial Span from CANTAB, Benton's Judge of Line Orientation test (JoLO), and Montreal Cognitive Assessment test (MoCA). The results revealed that younger participants showed better performance than older participants on both the Egocentric and Allocentric Spatial Memory Tasks, although only the Egocentric test was able to discriminate between younger, middle, and older elderly participants. Learning effect was found in Allocentric Spatial Memory Task in younger and older groups, but not in the middle group. Allocentric and egocentric performance was not related to other visuospatial neuropsychological scores and gender did not influence performance in any task. Egocentric and Allocentric Spatial Memory Tasks may be useful tools in early screening for cognitive decline, as they are able to detect age differences in the cognitive unimpaired elderly population.

Abstract
The characteristics of indoor light (intensity, spectral, spatial distribution) originating from outdoors have been studied using experimental and modeling tools. They are influenced by many parameters such as building location, meteorological conditions, and the type of window. They have a direct impact on indoor air quality through a change in chemical processes by varying the photolysis rates of indoor pollutants. Transmittances of different windows have been measured and exhibit different wavelength cutoffs, thus influencing the potential of different species to be photolysed. The spectral distribution of light entering indoors through the windows was measured under different conditions and was found to be weakly dependent on the time of day for indirect cloudy, direct sunshine, partly cloudy conditions contrary to the light intensity, in agreement with calculations of the transmittance as a function of the zenithal angle and the calculated outdoor spectral distribution. The same conclusion can be drawn concerning the position within the room. The impact of these light characteristics on the indoor chemistry has been studied using the INCA-Indoor model by considering the variation in the photolysis rates of key indoor species. Depending on the conditions, photolysis processes can lead to a significant production of radicals and secondary species.

Abstract
OH and HO2 profiles measured in a real environment have been compared to the results of the INCA-Indoor model to improve our understanding of indoor chemistry. Significant levels of both radicals have been measured and their profiles display similar diurnal behavior, reaching peak concentrations during direct sunlight (up to 1.6×106 and 4.0×107 cm-3 for OH and HO2 , respectively). Concentrations of O3 , NOx , volatile organic compounds (VOCs), HONO, and photolysis frequencies were constrained to the observed values. The HOx profiles are well simulated in terms of variation for both species (Pearson's coefficients: pOH =0.55, pHO2 =0.76) and concentration for OH (mean normalized bias error: MNBEOH =-30%), HO2 concentration being always underestimated (MNBEHO2 =-62%). Production and loss pathways analysis confirmed HONO photolysis role as an OH precursor (here up to 50% of the production rate). HO2 formation is linked to OH-initiated VOC oxidation. A sensitivity analysis was conducted by varying HONO, VOCs, and NO concentrations. OH, HO2 , and formaldehyde concentrations increase with HONO concentrations; OH and formaldehyde concentrations are weakly dependent on NO, whereas HO2 concentrations are strongly reduced with increasing NO. Increasing VOC concentrations decreases OH by consumption and enhances HO2 and formaldehyde.

Abstract
The photolysis of HONO has been found to be the oxidation driver through OH formation in the indoor air measurement campaign SURFin, an extensive campaign carried out in July 2012 in a classroom in Marseille. In this study, the INCA-Indoor model is used to evaluate different HONO formation mechanisms that have been used previously in indoor air quality models. In order to avoid biases in the results due to the uncertainty in rate constants, those parameters were adjusted to fit one representative day of the SURFin campaign. Then, the mechanisms have been tested with the optimized parameters against other experiments carried out during the SURFin campaign. Based on the observations and these findings, we propose a new mechanism incorporating sorption of NO2 onto surfaces with possible saturation of these surfaces. This mechanism is able to better reproduce the experimental profiles over a large range of conditions.

Abstract
BACKGROUND This phase II study aims to evaluate the efficacy and safety of biweekly cetuximab in combination with oxaliplatin, leucovorin, and fluorouracil (FOLFOX-4) as first-line treatment of metastatic wild-type KRAS colorectal cancer. METHODS Previously untreated patients with wild-type KRAS tumours received biweekly cetuximab (500 mg/m2 on day 1) plus FOLFOX-4 (oxaliplatin 85 mg/m2 on day 1, leucovorin 200 mg/m2 on days 1 and 2, and fluorouracil as a 400 mg/m2 bolus followed by a 22-hour 600 mg/m2 infusion on day 1 and 2). Treatment was continued until disease progression, onset of unacceptable toxicities, metastases surgery, or discontinuation request. The primary endpoint was ORR. RESULTS The intention-to-treat population included 99 patients with a median age of 64.1 years (range, 34-82). The ORR was 60.6% (95% CI, 50.3% to 70.3%). The median follow-up was 17.8 months; the median OS and PFS were 20.8 and 10.1 months, respectively. Metastases from colorectal cancer were surgically resected in 26 (26.3%) patients, with complete resection achieved in 18 (69.2%) patients. Median PFS and OS in patients undergoing metastatic resection were 12.6 and 29.5 months, respectively. The most common grade 3-4 toxicities were neutropenia (32.3%), acne-like rash (15.2%) and diarrhoea (11.1%). CONCLUSIONS The efficacy of the biweekly combination of cetuximab with FOLFOX-4 in patients with wild-type KRAS tumours supports the administration of cetuximab in a dosing regimen more convenient for patients and healthcare providers. The activity of the biweekly administration is similar to what has been reported for the weekly regimen. Reported toxicity was also consistent with the known toxicity profile of weekly cetuximab. TRIAL REGISTRATION EudraCT Number 200800690916.

Abstract
Abstract
Glioblastoma multiforme is one of the most aggressive and fatal brain cancers mostly because of the highly invasive nature of glioma cells. The ability of glioma cells to disperse to healthy brain stroma makes surgical and chemotherapeutic treatments mostly ineffective. Microglia infiltrate most gliomas and release factors, which favor tumor growth and dispersal. We hypothesize that microglia residing within the tumor stimulate glioma cell migration and dispersal through the phospholipase C (PLC)γ1 and proline rich tyrosine kinase 2 (Pyk2) signaling cascade. In the present study, we investigated rodent C6 and GL261 as well as human glioma cell lines with varying levels of invasiveness: U-87MG, A172, and HS683. Using a standard invasion assay, we demonstrated that the presence of rodent or immortalized human microglia in the bottom compartment of Boyden chambers activated invasion of all glioma cell types. Knock-down of PLCγ1 and Pyk2 proteins using siRNA reversed the stimulatory effect of microglia on glioma invasion in both cell lines. Pharmacological blockers of PLC (U73872 1nM) and Pyk2/focal adhesion kinase (FAK) (PF562271 20nM) also completely eliminated the ability of microglia to stimulate glioma cell migration in a wound healing assay. Using Western blot, we found upregulation of phosphorylated Tyr579/580 Pyk2 protein in glioma cells treated with microglia conditioned medium. Taken together, these data indicate that microglial cells activate glioma cell migration/dispersal through the pro-migratory Pyk2 and PLCγ1 signaling pathway in glioma cells.

Abstract
In some jurisdictions attempts have been made to limit or deny access to medical records for victims of torture seeking remedy or reparations or for individuals who have been accused of crimes based on confessions allegedly extracted under torture. The following article describes the importance of full disclosure of all medical and other health records, as well as legal documents, in any case in which an individual alleges that they have been subjected to torture or other forms of cruel, inhuman or degrading treatment of punishment. A broad definition of what must be included in the terms medical and health records is put forward, and an overview of why their full disclosure is an integral part of international standards for the investigation and documentation of torture (the Istanbul Protocol). The fact that medical records may reveal the complicity or direct participation of healthcare professionals in acts of torture and other ill-treatment is discussed. A summary of international law and medical ethics surrounding the right of access to personal information, especially health information in connection with allegations of torture is also given.

Abstract
Genetic analyses of population structure can be placed in explicit environmental contexts if appropriate environmental data are available. Here, we use high-coverage and high-resolution oceanographic and genetic sequence data to assess population structure patterns and their potential environmental influences for humpback dolphins in the Western Indian Ocean. We analyzed mitochondrial DNA data from 94 dolphins from the coasts of South Africa, Mozambique, Tanzania and Oman, employing frequency-based and maximum-likelihood algorithms to assess population structure and migration patterns. The genetic data were combined with 13 years of remote sensing oceanographic data of variables known to influence cetacean dispersal and population structure. Our analyses show strong and highly significant genetic structure between all putative populations, except for those in South Africa and Mozambique. Interestingly, the oceanographic data display marked environmental heterogeneity between all sampling areas and a degree of overlap between South Africa and Mozambique. Our combined analyses therefore suggest the occurrence of genetically isolated populations of humpback dolphins in areas that are environmentally distinct. This study highlights the utility of molecular tools in combination with high-resolution and high-coverage environmental data to address questions not only pertaining to genetic population structure, but also to relevant ecological processes in marine species.

Abstract
This article provides a classification of primary progressive aphasia (PPA) and its 3 main variants to improve the uniformity of case reporting and the reliability of research results. Criteria for the 3 variants of PPA--nonfluent/agrammatic, semantic, and logopenic--were developed by an international group of PPA investigators who convened on 3 occasions to operationalize earlier published clinical descriptions for PPA subtypes. Patients are first diagnosed with PPA and are then divided into clinical variants based on specific speech and language features characteristic of each subtype. Classification can then be further specified as "imaging-supported" if the expected pattern of atrophy is found and "with definite pathology" if pathologic or genetic data are available. The working recommendations are presented in lists of features, and suggested assessment tasks are also provided. These recommendations have been widely agreed upon by a large group of experts and should be used to ensure consistency of PPA classification in future studies. Future collaborations will collect prospective data to identify relationships between each of these syndromes and specific biomarkers for a more detailed understanding of clinicopathologic correlations.

Abstract
UNLABELLED Haemophilia A (HA) is X-chromosome linked bleeding disorders caused by deficiency of the coagulation factor VIII (FVIII). It is caused by FVIII gene intron 22 inversion (Inv22) in approximately 45% and by intron 1 inversion (Inv1) in 5% of the patients. Both inversions occur as a result of intrachromosomal recombination between homologous regions, in intron 1 or 22 and their extragenic copy located telomeric to the FVIII gene. The aim of this study was to analyze the presence of these mutations in 25 HA Costa Rican families. PATIENTS, METHODS We studied 34 HA patients and 110 unrelated obligate members and possible carriers for the presence of Inv22or Inv1. Standard analyses of the factor VIII gene were used incl. Southern blot and long-range polymerase chain reaction for inversion analysis. RESULTS We found altered Inv22 restriction profiles in 21 patients and 37 carriers. It was found type 1 and type 2 of the inversion of Inv22. During the screening for Inv1 among the HA patient, who were Inv22 negative, we did not found this mutation. DISCUSSION Our data highlight the importance of the analysis of Inv22 for their association with development of inhibitors in the HA patients and we are continuous searching of Inv1 mutation. This knowledge represents a step for genetic counseling and prevention of the inhibitor development.

Abstract
The aim of this study was to evaluate the effects of acute alcohol consumption and vitamin E co-treatment upon oxidative stress parameters in rats tongue. Thirty-eight, Wistar rats were separated into five groups (alcohol, alcohol/vitamin E, control, Tween, vitamin E). Alcohol and alcohol vitamin E groups had the standard diet, and 40% alcohol on drinking water. Other groups were fed with the same standard diet and water ad libitum. Vitamin E was given by gavage to vitamin E and alcohol/vitamin E rats twice a week. Alcohol and control groups were subjected to saline gavage and Tween group to 5% Tween 80 solution, the vitamin E vehicle. At day 14, the animals were anesthetized and specimens were obtained from tongue. Lipid peroxidation (TBARS), protein oxidative damage, catalase (CAT) and superoxide dismutase (SOD) activities were quantified. Alcohol group decreased TBARS in relation to control group and alcohol vitamin-treated animals decreased TBARS when compared to Tween and vitamin E groups. SOD activity was lower and CAT activity was higher in animals treated with both alcohol and vitamin E. These results suggest that short-term alcohol consumption decreases lipid peroxidation levels. Alternatively, alcohol/vitamin E group increased CAT, showing the toxicity of this association.

Abstract
PURPOSE Despite major advances in the treatment of classic Hodgkin's lymphoma (cHL), approximately 30% of patients in advanced stages may eventually die as result of the disease, and current methods to predict prognosis are rather unreliable. Thus, the application of robust techniques for the identification of biomarkers associated with treatment response is essential if new predictive tools are to be developed. EXPERIMENTAL DESIGN We used gene expression data from advanced cHL patients to identify transcriptional patterns from the tumoral cells and their nonneoplastic microenvironment, associated with lack of maintained treatment response. Gene-Set Enrichment Analysis was used to identify functional pathways associated with unfavorable outcome that were significantly enriched in either the Hodgkin's and Reed-Sternberg cells (regulation of the G2-M checkpoint, chaperones, histone modification, and signaling pathways) or the reactive cell microenvironment (mainly represented by specific T-cell populations and macrophage activation markers). RESULTS To explore the pathways identified previously, we used a series of 52 formalin-fixed paraffin-embedded advanced cHL samples and designed a real-time PCR-based low-density array that included the most relevant genes. A large majority of the samples (82.7%) and all selected genes were analyzed successfully with this approach. CONCLUSIONS The results of this assay can be combined in a single risk score integrating these biological pathways associated with treatment response and eventually used in a larger series to develop a new molecular outcome predictor for advanced cHL.

Abstract
INTRODUCTION The fetus is most vulnerable to severe iodine deficiency and hypothyroidism during pregnancy. The effects of mild iodine deficiency and subclinical hypothyroidism are poorly known. The present study assesses the association between thyroid hormones (TH)s and urinary iodine concentration (UIC) in healthy pregnant women and the birth weight of their children. METHODS About 657 pregnant women were recruited in Sabadell and followed until delivery. The association between THs during the first trimester, UIC during the first and third trimesters, and birth weight was studied in 557, 251, and 528 mother-newborn pairs respectively, using linear and logistic regression models adjusted for potential confounders. Only 239 women had all the data available (thyroid function and UIC at the first and third trimesters). Six percent of newborns were classified as small for gestational age (SGA). RESULTS The median UIC was 95 and 104 microg/l during the first and third trimesters respectively. Women with the third trimester UICs between 100 and 149 microg/l had lower risk of having an SGA newborn than women with UICs below 50 microg/l (adjusted OR (95%CI): 0.15 (0.03-0.76). There was no significant reduction in SGA among mothers with higher UICs. Lower free thyroxine and higher TSH levels during the first trimester were not associated with birth weight or SGA. Nevertheless, the analyses were repeated including only those women with all the data available, and high TSH levels became statistically significantly associated with lower birth weight and higher risk of SGA. CONCLUSIONS The present study suggests that iodine status during pregnancy may be related to prenatal growth in healthy women.
