Resilience and psychosocial factors in adult with epilepsy: A longitudinal study.

PURPOSE: Resilience is conceptually characterized as a dynamic process encompassing positive adaptation in the context of significant adversity. Our goal was to assess the resilience in people with epilepsy (PWE) and how it impacts longitudinally on psychosocial factors, with a particular focus on the manifestation of stigmatization-related feelings. METHODS: We consecutively enrolled 78 adults PWE (42.5 ± 16.2 years old); among them 36 (46.1 %) were seizure-free. All subjects completed at baseline (T0) the Resilience Scale (RS-14) and questionnaires for the assessment of depressive symptoms, anxiety and quality of life: respectively, Beck Depression Inventory-II (BD-II), Generalized Anxiety Disorder-7 (GAD-7) and QOLIE-31 (Q31). All patients were followed up prospectively and re-evaluated after 6-22 months (T1; mean: 14 ± 8 months; median 14 months); at follow up they also completed the Stigma Scale of Epilepsy (SSE) for the assessment of the stigma associated with epilepsy. We correlated resilience values with all psychosocial scores at T0 and T1. Factors associated with resilient and vulnerable outcomes were identified. Finally, a multiple stepwise regression analysis was applied to identify predictors for resilience and stigma perception. RESULTS: The results showed for the RS-14 score a significant direct correlation with the Q31 (p < 0.001) and an inverse correlation with the depressive and anxiety symptoms at both times (T0 and T1), as evaluated with BDI-II (p < 0.001) and GAD-7 (p < 0.001). Finally, we found a significant inverse correlation between RS-14 at T0 and the levels of stigmatization assessed with SSE at T1 (p =.015). Using a multiple stepwise regression analysis separately for resilience and stigma perception, depressive symptoms turned out as the best predictors for both variables. Finally, considering longitudinal evaluation we did not observe significant changes in depressive and anxious symptoms, despite a significant reduction in the total number of seizures at follow up. CONCLUSIONS: Our study showed that depressive symptoms, anxiety and quality of life were significantly associated with resilience in PwE. Finally, as a novel finding resilience was proved to affect the perception of stigma related to epilepsy more than seizures.

Using IOTA terminology to evaluate fetal ovarian cysts: analysis of 51 cysts over 10-year period.

OBJECTIVES: To describe ultrasound features of fetal ovarian cysts as reported by the original ultrasound examiner, to apply International Ovarian Tumor Analysis (IOTA) terminology after retrospective analysis of the images and to describe patient management and evolution of fetal cysts during pregnancy and after delivery. METHODS: This retrospective observational study included pregnant women diagnosed on ultrasound examination with a fetal ovarian cyst at the Prenatal Diagnosis Division of the Bambino Gesù Children's Hospital, in Rome, between March 2011 and May 2020. Cysts were classified by the original ultrasound examiner as 'simple' (unilocular anechoic cyst) or 'complex' (cyst with other morphology). In addition, three ultrasound examiners, experienced in gynecologic ultrasound, classified retrospectively the fetal ovarian cysts according to IOTA terminology, by reviewing stored ultrasound images. The evolution of these fetal ovarian cysts during pregnancy and after birth was recorded. RESULTS: Included were 51 ovarian cysts in 48 fetuses. Of the 51 cysts, 29 (56.9%) had been classified by the original ultrasound examiner as 'simple', and 22 (43.1%) as 'complex'. Of the simple cysts, the majority (20/29 (69.0%)) resolved spontaneously after delivery, 2/29 (6.9%) resolved following intrauterine aspiration, 2/29 (6.9%) resolved after postnatal aspiration and 5/29 (17.2%) underwent surgery due to persistence after delivery; in all five, normal ovarian parenchyma without signs of necrosis was observed at histology. Of the complex cysts, 7/22 (31.8%) resolved spontaneously. The other 15/22 (68.2%) were removed surgically and, at histology, necrosis was observed in most (12/15 (80.0%)), while a benign epithelial cyst with normal ovarian parenchyma was observed in 3/15 (20%). After reviewing the ultrasound images and applying IOTA terminology, all 51 (100%) fetal cysts were described as unilocular; 29/51 (56.9%) cysts showed anechoic content (described as simple cysts by the original ultrasound examiner), and 10/51 (19.6%) had low-level, 1/51 (2.0%) had ground-glass, 9/51 (17.6%) had hemorrhagic, 1/51 (2.0%) had mixed and 1/51 (2.0%) had undefined content (all described as complex by the original ultrasound examiner). Among the 29 anechoic ovarian cysts, resolution was observed in most (24/29, 82.8%) cases. Similarly, resolution was observed in 7/10 (70.0%) cysts with low-level content. Resolution was not observed in any of the other 12 cysts and all of these cases underwent surgery, with evidence of necrosis being observed in 11 (91.7%). CONCLUSIONS: Applying IOTA terminology provided a more detailed and accurate description of fetal ovarian cysts compared with the original classification into 'simple' and 'complex' categories. Anechoic cysts (described as simple cysts by the original ultrasound examiner) and cysts with low-level content (described as complex by the original ultrasound examiner) frequently resolved spontaneously. Cysts with ground-glass, hemorrhagic, mixed or undefined content were frequently associated with necrosis at histology following surgery. © 2022 The Authors.

Determinants of medication adherence in people with epilepsy: A multicenter, cross-sectional survey.

OBJECTIVES: Poor medication adherence in people with epilepsy (PwE) increases mortality, hospitalization, and poor quality of life, representing a critical challenge for clinicians. Several demographic, clinical, and neuropsychological factors were singularly found associated with medication adherence in several studies, but the literature lacks a comprehensive study simultaneously assessing all these variables. METHODS: We performed a multicenter and cross-sectional study using online questionnaires with the following clinical scales: Morisky Medication Adherence Scale (MMAS-8), Quality of Life in Epilepsy Inventory 31 (QoLIE-31), Beck Depression Inventory-II (BDI-II), Generalized Anxiety Disorder-7 (GAD-7) and 14-item Resilience scale (RES14) in a population of 200 PwE. We used the ANOVA test and Spearman's correlation to evaluate the relationship between medication adherence and demographic, clinical (seizure frequency, number of anti-seizure medications), and neuropsychological characteristics. We trained separate machine learning models (logistic regression, random forest, support vector machine) to classify patients with medium-high adherence (MMAS-8 ≥ 6) and poor adherence (MMAS-8 < 6) and to identify the main features that influence adherence. RESULTS: Women were more adherent to medication (p-value = 0.035). Morisky Medication Adherence Scale -8 showed a direct correlation with RES14 (p-value = 0.001) and age (p-value = 0.001), while was inversely correlated with BDI-II (p-value = 0.001) and GAD-7 (p-value = 0.001). In our model, the variables mostly predicting treatment adherence were QoLIE-31 subitems, followed by age, resilience, anxiety, years of school, and disease duration. CONCLUSION: Our study confirms that gender, age, and neuropsychological traits are relevant factors in predicting medication adherence to PwE. Furthermore, our data provided the first evidence that machine learning on multidimensional self-report questionnaires could help to develop a decisional support system in outpatient epilepsy clinics.

Resilience predicts and modulates anxiety severity in people with epilepsy.

BACKGROUND: Anxiety is one of the most relevant psychiatric comorbidities in people with epilepsy (PwE). The role of resilience (RES) in the development of anxiety is not well understood. We purposed to better characterize RES impact on anxiety severity in PwE. MATERIALS AND METHODS: One hundred and seventy-six PwE underwent online surveys including a collection of socio-demographic, seizure-related, and psychological variables. PwE were grouped according to the data collected; anxiety levels were compared through non-parametric statistics. Hierarchical regression analysis (HRA) and logistic regression were performed to characterize RES contribute in predicting the presence and the severity of anxiety. Mediation/moderation analysis was performed to evaluate causal effects among RES, depression, and anxiety. RESULTS: Anxiety did not differ according to socio-demographic and seizure-related variables, exemption for the presence of drug-related adverse effects. Depression, RES, and sleep quality provided the major contribute on anxiety variance. The addiction of RES level in HRA and logistic regression provided a significant increase of R-squared value (p-value = 0.02) and of area under the curve (p-value = 0.03), respectively. RES modulated depression/anxiety relationship (p-value < 0.001), whereas depression did not mediate RES/anxiety correlation (p-value = 0.68). CONCLUSIONS: We demonstrated that RES is a significant independent predictor of anxiety in PwE and is able to modulate depression impact on anxiety. Moreover, we confirmed the relevance of depression and sleep quality on anxiety severity.

Quantitative measures of the resting EEG in stroke: a systematic review on clinical correlation and prognostic value.

OBJECT: Quantitative electroencephalography (qEEG) has shown promising results as a predictor of clinical impairment in stroke. We systematically reviewed published papers that focus on qEEG metrics in the resting EEG of patients with mono-hemispheric stroke, to summarize current knowledge and pave the way for future research. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we systematically searched the literature for papers that fitted our inclusion criteria. Rayyan QCRR was used to allow deduplication and collaborative blinded paper review. Due to multiple outcomes and non-homogeneous literature, a scoping review approach was used to address the topic. RESULTS: Or initial search (PubMed, Embase, Google scholar) yielded 3200 papers. After proper screening, we selected 71 papers that fitted our inclusion criteria and we developed a scoping review thar describes the current state of the art of qEEG in stroke. Notably, among selected papers 53 (74.3%) focused on spectral power; 11 (15.7%) focused on symmetry indexes, 17 (24.3%) on connectivity metrics, while 5 (7.1%) were about other metrics (e.g. detrended fluctuation analysis). Moreover, 42 (58.6%) studies were performed with standard 19 electrodes EEG caps and only a minority used high-definition EEG. CONCLUSIONS: We systematically assessed major findings on qEEG and stroke, evidencing strengths and potential pitfalls of this promising branch of research.

Dietary intake and major food sources of polyphenols in people with type 2 diabetes: The TOSCA.IT Study.

PURPOSE: Proper evaluation of polyphenols intake at the population level is a necessary step in order to establish possible associations with health outcomes. Available data are limited, and so far no study has been performed in people with diabetes. The aim of this work was to document the intake of polyphenols and their major food sources in a cohort of people with type 2 diabetes and in socio-demographic subgroups. METHODS: We studied 2573 men and women aged 50-75 years. Among others, anthropometry was measured by standard protocol and dietary habits were investigated by food frequency questionnaire (EPIC). The intake of polyphenols was evaluated using US Department of Agriculture and Phenol-Explorer databases. RESULTS: The mean total polyphenol intake was 683.3 ± 5.8 mg/day. Non-alcoholic beverages represented the main food source of dietary polyphenols and provided 35.5% of total polyphenol intake, followed by fruits (23.0%), alcoholic beverages (14.0%), vegetables (12.4%), cereal products and tubers (4.6%), legumes (3.7%) and oils (2.1%); chocolate, cakes and nuts are negligible sources of polyphenols in this cohort. The two most important polyphenol classes contributing to the total intake were flavonoids (47.5%) and phenolic acids (47.4%). Polyphenol intake increased with age and education level and decreased with BMI; furthermore, in the northern regions of Italy, the polyphenol intake was slightly, but significantly higher than in the central or southern regions. CONCLUSIONS: The study documents for the first time the intake of polyphenols and their main food sources in people with diabetes using validated and complete databases of the polyphenol content of food. Compared with published data, collected in people without diabetes, these results suggest a lower intake and a different pattern of intake in people with diabetes.

Correlation in brain networks at different time scale resolution.

Assessing brain connectivity makes up a major issue in the field of network dynamics and neuroscience. Conventional experimental techniques are based on functional imaging and magnetoencephalography, allowing to reconstruct the activity of relatively small brain volume elements. A common approach to identify networks consists in singling out sets of elements that maintain a correlated activity over time. Despite the general consensus that these networks are detectable on a time window of 10 s, no study is presently available on the distribution and thus the reliability of this time scale. In this work, we describe a new method to assess time scales on which correlations between network elements occur and to consequently identify the underlying network structures. The analysis relies on the evaluation of quasi-zero-delay cross-correlation between power sequences associated with distinct volume elements. By changing the width of the running window used to analyze successive segments of time series, the behavior of cross-correlation at different time scales was investigated. The onset of connectivity was estimated to be observable at about 30 s. The method was applied to a set of volume elements that are supposed to belong to a known resting-state network, namely the Default Mode Network. Fully connected networks were identified, provided that a sufficiently long time scale is considered. Our method makes up a new tool for the investigation of the temporal dynamics of networks.

Observation of 7pP23/2→7dD2 optical transitions in 209 and 210 francium isotopes.

We report on the direct experimental observation of the 7pP23/2→7dD2 optical transitions in 209 and 210 francium isotopes. By continuously monitoring the fluorescence emitted by the isotopes collected in a magneto-optical trap (MOT), the electric dipole transitions 7pP23/2→7dD25/2 of Fr209, not yet experimentally observed, and 7pP23/2→7dD25/2, 7pP23/2→7dD25/2 of Fr210 were detected as sub-Doppler depletion dips of the cold atom population. This approach allowed unambiguous identification of the excited state hyperfine structures, even in the absence of a large stable vapor. Our findings demonstrate the effectiveness and the flexibility of fluorescence monitoring of trap depletion upon laser excitation, and broaden the experimental knowledge of francium isotopes and their electronic and nuclear properties. These results will have a relevant impact on ongoing researches for low-energy testing of fundamental symmetries with francium, from atomic parity non-conservation to the electron dipole moment.

Analysis of current data on the use of topical rapamycin in the treatment of facial angiofibromas in tuberous sclerosis complex.

BACKGROUND: Tuberous sclerosis complex (TSC) is an autosomal dominant neurocutaneous syndrome causing hamartomatous growths in multiple organs. Facial angiofibromas occur in up to 80% of patients and can be highly disfiguring. Treatment for these lesions has historically been challenging. Recently, topical rapamycin has been proposed as an effective option to treat angiofibromas but a commercially available compound has not yet been developed. OBJECTIVES: The aim of this review is to analyse the current data on the use of topical rapamycin in the treatment of angiofibromas in TSC, focusing on the risk-benefit profile. METHODS: A retrospective review of the English-language literature was conducted. RESULTS: Sixteen reports describing the use of topical rapamycin in the treatment of angiofibromas in TSC were considered, involving a total of 84 patients. An improvement of the lesions has been shown in 94% of subjects, particularly if the treatment was started at early stages. Several different formulations (ointment, gel, solution and cream) with a wide range of concentrations (0.003%-1%) were proposed. Only 4 local adverse side-effects were reported after the use of rapamycin solution. CONCLUSION: Topical rapamycin can be considered a safe option for the treatment and the prevention of facial angiofibromas in younger patients, but the best formulation has not been established. Our review demonstrates that ointment and gel should be preferred, but it is not clear which concentration is optimal. Long-term and comparative studies between topical rapamycin and ablative techniques are required to establish which treatment has a better outcome and lower recurrence rate.

PIN6 is required for nectary auxin response and short stamen development.

The PIN family of proteins is best known for its involvement in polar auxin transport and tropic responses. PIN6 (At1g77110) is one of the remaining PIN family members in Arabidopsis thaliana to which a biological function has not yet been ascribed. Here we report that PIN6 is a nectary-enriched gene whose expression level is positively correlated with total nectar production in Arabidopsis, and whose function is required for the proper development of short stamens. PIN6 accumulates in internal membranes consistent with the ER, and multiple lines of evidence demonstrate that PIN6 is required for auxin-dependent responses in nectaries. Wild-type plants expressing auxin-responsive DR5:GFP or DR5:GUS reporters displayed intense signal in lateral nectaries, but pin6 lateral nectaries showed little or no signal for these reporters. Further, exogenous auxin treatment increased nectar production more than tenfold in wild-type plants, but nectar production was not increased in pin6 mutants when treated with auxin. Conversely, the auxin transport inhibitor N-1-naphthylphthalamic acid (NPA) reduced nectar production in wild-type plants by more than twofold, but had no significant effect on pin6 lines. Interestingly, a MYB57 transcription factor mutant, myb57-2, closely phenocopied the loss-of-function mutant pin6-2. However, PIN6 expression was not dependent on MYB57, and RNA-seq analyses of pin6-2 and myb57-2 mutant nectaries showed little overlap in terms of differentially expressed genes. Cumulatively, these results demonstrate that PIN6 is required for proper auxin response and nectary function in Arabidopsis. These results also identify auxin as an important factor in the regulation of nectar production, and implicate short stamens in the maturation of lateral nectaries.

Light desorption from an yttrium neutralizer for Rb and Fr magneto-optical trap loading.

We present here the first evidence of photodesorption induced by low-intensity non-resonant light from an yttrium thin foil, which works as a neutralizer for Rb and Fr ions beam. Neutral atoms are suddenly ejected from the metal surface in a pulsed regime upon illumination with a broadband flash light and then released in the free volume of a pyrex cells. Here atoms are captured by a Magneto-Optical Trap (MOT), which is effectively loaded by the photodesorption. Loading times of the order of the flash rise time are measured. Desorption is also obtained in the continuous regime, by exploiting CW visible illumination of the metallic neutralizer surface. We demonstrate that at lower CW light intensities vacuum conditions are not perturbed by the photodesorption and hence the MOT dynamics remains unaffected, while the trap population increases thanks to the incoming desorbed atoms flux. Even with the Y foil at room temperature and hence with no trapped atoms, upon visible illumination, the number of trapped atoms reaches 10(5). The experimental data are then analyzed by means of an analytical rate equation model, which allows the analysis of this phenomenon and its dynamics and allows the determination of critical experimental parameters and the test of the procedure in the framework of radioactive Francium trapping. In this view, together with an extensive investigation of the phenomenon with (85)Rb, the first demonstration of the photodesorption-aided loading of a (210)Fr MOT is shown.

How autistic women are aware of their body and take care of their health? Focus on menstruation cycles and gynecological care.

Objective: The combination of femininity and inequality is an increasingly studied in the field of social medicine, even more if the girls or women in question experience conditions of disability or neurodivergence. The onset of menstruation, menarche, constitutes a significant and transformative event in women's lives comprising a true and proper watershed in mental and reproductive health and sexual welfare. The onset of menstruation has a profound effect not just for girls but, in the case of disabled girls, for the whole family. In this scoping review, we have researched the literature in studies which consider the issue of menstruation and autism. The works in scientific literature have been selected which, in the last 5 years, investigated the issue of menstrua-tion for autistic girls and/or women. Results: Selected studies, although few in number, have all equally evidenced the total lack of in-depth understanding of this theme, notwithstanding the fact that females, girls and women with autism would benefit from specialized services if these existed. Families, girls and women involved, moreover, although not experiencing menstruation per se in a negative light, note a deterioration in their condition particularly in respect of sensorial perception and the intensification of anxious depressive instances. This work highlights the need to deepen the aspects concerning the period in autistic girls/women, up to now the question appears to have been little studied, investigated in an uneven way. We propose a social medical program to improve sexual-affective knowledge and body awareness in autistic people.

Use of Oral Chroma™ in the assessment of volatile sulfur compounds in patients with fixed protheses.

Prosthetic rehabilitation improves the patient's quality of life and oral health. The purpose of the present study was to assess the production of volatile sulfur compounds (VSCs) using Oral Chroma™ in patients wearing provisional and permanent fixed prosthesis, who were treated or not, with supportive non-surgical periodontal therapy. A total of 10 healthy patients not affected by periodontal disease and who needed the restoration of at least two edentulous single sites were included in the present study. Registrations of VSCs were carried out with a Gas Chromatograph OralChroma™ (Oral Chroma™, Abimedical, Abilit Corp., Osaka, Japan) one month after placement of the provisional restoration (group 1) and one month after placement of the final restoration (group 3). After each measurement, professional oral hygiene was carried out both on patients with provisional (group 2) and permanent prostheses (group 4) and VSC values were registered. The results showed that there were no statistical significant differences in the VSC quantity between groups with temporary or permanent prostheses. Meanwhile, statistically significant differences were found in VCS values between groups before and after the professional health care session (p less than 0.05). Also it was observed that dimethyl sulphide (CH3)2S was present in all the study groups. The present preliminary study suggests that OralChroma™ produce a comprehensive assessment of VSC in the clinical diagnosis of halitosis and that professional oral hygiene seems to influence VSC production. However, further clinical long-term studies with a larger sample size are necessary for a better understanding of halitosis manifestation in patients wearing provisional and permanent fixed prosthesis.

Expanding the product portfolio of carbon dioxide and hydrogen-based gas fermentation with an evolved strain of Clostridium carboxidivorans.

CO2:H2-based gas fermentation with acetogenic Clostridium species are at an early stage of development. This work exploited the Adaptive Laboratory Evolution technique to improve the growth of C. carboxidivorans P7 on CO2 and H2. An adapted strain with decreased growth lag phase and improved biomass production was obtained. Genomic analysis revealed a conserved frameshift mutation in the catalytic subunit of the hexameric hydrogenase gene. The resulted truncated protein variant, most likely lacking its functionality, suggests that other hydrogenases might be more efficient for H2-based growth of this strain. Furthermore, the adapted strain generated hexanol as primary fermentation product. For the first time, hexanol was produced directly from CO2:H2 blend, achieving the highest maximum productivity reported so far via gas fermentation. Traces of valerate, pentanol, eptanol and octanol were observed in the fermentation broth. The adapted strain shows promising to enrich the product spectrum targetable by future gas fermentation processes.

Parents-children co-regulation as therapeutic variable and target in autism spectrum disorders. From observation of drive to need of cooperative parent-mediated therapy.

Abstract: Autism spectrum disorders (ASDs) belong to the category of neurodevelopmental disorders. ASD emerges in early childhood and involves deficits in communication, language, behavioural inflexibility and fixity, and sensorial neurodivergent perception. ASDs have a biological pathogenesis related to genetic and epigenetic factors. Additionally, research has shown that starting from childhood, autistic persons could find emotional regulation challenging during communication with caregivers. The importance of emotional co-regulation has always been under-lined in psychology, starting with Freud who introduced the concept of the Compassionate Other. Emotional difficulties are grasped immediately and almost instinctively by parents, who try to modulate their approach to the child's needs from the very beginning. This paper seeks to highlight the importance of emotional co-regulation as a wake-up call-in developmental trajectories that present peculiarities or anomalies. It also emphasizes the significance of emotional co-regulation as a useful tool for intervening in the dysfun-ctionality of such trajectories. This intervention aims to directly involve parents in treatment, as seen in Cooperative parent-mediated therapy. This approach is crucial for facilitating the evolution of the cognitive framework while utilizing this target. This article aims to review the most recent literature on co-regulation after explaining the theoretical framework that gave rise to this concept. It's now well established the importance of adopting a develop-mental approach that starts from the bodily dimension as the basis for the relationship with caregivers, pairs, and unfamiliar people. It is from this basis that starts the affective, emotional, and cognitive construction of the internal and external world of the child. This scoping review takes into account the most recent evidence on co-regulation and autism, emphasizing the importance of this process in diagnostic and therapeutic settings.

Vagal nerve stimulation cycles alter EEG connectivity in drug-resistant epileptic patients: A study with graph theory metrics.

OBJECTIVE: Vagal Nerve Stimulation (VNS) is an effective treatment for Drug-Resistant (DR) epilepsy. Albeit the corroborated effectiveness of VNS, little is known about how VNS works. We aim to leverage quantitative Electroencephalography (qEEG) to study how the brain responds to VNS cycles. METHODS: Eighteen subjects with DR epilepsy were enrolled in our study. 64-channel EEG was recorded during VNS stimulation. Periods of stimulation (VNS), preceding (preVNS) and following stimulation (postVNS) were identified via an electrode placed on the stimulator. We used qEEG analysis to assess changes in spectral and network activity that characterize these conditions. Graph theory metrics were used to calculate differences in network connectivity. RESULTS: No differences were found in spectral activity between preVNS, VNS, and postVNS. Graph theory showed consistent changes in network organization expressed by Small World Index (SWI), Betweenness Centrality (BtwC), and Global Efficiency (gE). These changes were most significant in the slow EEG bands. CONCLUSIONS: In DR epilepsy, VNS has a significant effect on brain network activity, as assessed by EEG connectivity, acting on widespread network distribution rather than band-power. SIGNIFICANCE: Our findings support the hypothesis that VNS acts on epilepsy by influencing diffuse network connectivity in the brain.

Home literacy environments, interest in reading and emergent literacy skills of children with Down syndrome versus typical children.

BACKGROUND: The present study examined home literacy environments, children's interest in reading and emergent literacy skills of pre-school-aged children with Down syndrome (DS; n=20), school-aged children with DS (n=17) and typically developing children (n=18) matched on chronological age with the younger DS group and mental age (MA) with the older DS group. METHOD: Parents filled out questionnaires on their home literacy environments and their children's interest in reading. School-aged children with DS and typical children were assessed on cognitive functioning, receptive vocabulary, alphabet knowledge, familiarity with print conventions and comprehension of meaning. RESULTS: School-aged children with DS and typical children - as opposed to pre-school-aged children with DS - were exposed to more literacy-rich home environments and had greater interest in reading. School-aged children with DS also outperformed the MA-matched typical group on letter and sight word knowledge and familiarity with print conventions. CONCLUSIONS: Parents of children with DS tailor home literacy environments to their children's developmental levels. Confirming earlier studies, children with DS achieved some higher literacy skills than what was expected for their MA, emphasising the importance of early reading interventions for this population.

[Is the international normalised ratio a prognostic factor of mortality in intracerebral haemorrhage?]. / ¿Es el cociente normalizado internacional un factor pronóstico de mortalidad en hemorragias intracerebrales?

BACKGROUND: Oral anticoagulant therapy (ACO) is considered an independent predictor of mortality in patients with intracerebral haemorrhage (ICH), with the role of the international normalised ratio (INR) being unclear. The aim of this work is to evaluate the relationship between ACO and the INR value and the ICH volume, and to determine the relationship between both variables and mortality. PATIENTS AND METHODS: Patients were retrospectively analysed using the Private Community Cerebrovascular Hospital Register (Registro Cerebrovascular del Hospital Privado de Comunidad), between December 2003 and May 2009. Volumes of the haematomas (dependent variable) were calculated from the first image performed, using the abc/2 method. Independent variables were age, gender, vascular risk factors, site of bleeding, intraventricular dump, clinical severity (Glasgow scale), time to image, antiplatelet drugs, and INR value on admission. An analysis of the relationship between all these variables and mortality was also performed. RESULTS: A total of 327 patients with HIC were identified (35 with ACO). Median volume was higher in the anticoagulated patients (55ml vs 24ml P<.05), with no statistically significant relationship between volume and the other variables. In the multivariate analysis, a statistically significant higher mortality associated to volume was observed, but not with anticoagulation. CONCLUSIONS: Oral anticoagulation was associated with a higher initial volume of the haematoma, with no correlation between the INR value and volume. The HIC volume was directly related to mortality, however, like the volume, the INR was not associated with increased mortality.

Effects of cadmium on MAPK signalling pathways and HSP70 expression in a human trophoblast cell line.

The aim of this work was to provide a greater insight into the possible effects of Cd on signal transduction and stress-related pathways in reproductive tissues. Cd is a known placental toxin in both animals and humans. Our experiments were designed to study the influence of Cd on MAPK (ERK1/2, JNK1/2 and p38MAPK) activation in the extravillous trophoblast cell line, HTR-8/SVneo, used as an experimental model. We also studied the HSP70 response in cells exposed to Cd, since these proteins may have an important role in conferring protection and tolerance against teratogenic concentrations of the metal. The effects of Cd were compared with those of a well-known toxic agent, H2O2. The metal triggered MAPK activation in a dose- and time-dependent manner. At 30 microM Cd, stimulations of about 300%, 550% and 250% were observed for ERK1/2, JNK1/2, and p38MAPK, respectively. Phosphorylation of ERK1/2 and JNK1/2 was significantly induced after a 1-h exposure to 30 microM Cd, while that of p38MAPK occurred only after 8h. Similarly, H2O2 caused dose- and time-dependent activation of MAPK pathways. Cd potently stimulated HSP70 expression and that of related genes HSP70 A, B and C. H2O2 did not increase HSP70 and HSP70 A and B expression, while temporarily increasing HSP70C transcript levels. In conclusion, Cd triggers different stress responses in trophoblast cells involving HSP70 and SAPK, and also enhances ERK1/2 phosphorylation. Since MAPK dependent pathways play a crucial role during pregnancy, non-physiological activation by Cd exposure may disrupt normal functions in trophoblast cells.
