Red contra la tuberculosis y por la solidaridad: El compromiso de la sociedad civil
Despite the progress made in the last years,
the Tuberculosis remains a relevant public health
problem in many geographic areas of the world.
Tuberculosis is the paradigm of infectious disease
with a high social component, and in its approach,
measures aimed at reducing poverty, economic inequality
and the integration of the most vulnerable
groups cannot be ignored. Therefore, solidarity and
social justice are terms associated with the control
of this disease. The TBS Network, made up of various
institutions born from civil society, tries to inform
society and professionals about aspects of tuberculosis
prevention, control, diagnosis, treatment
and investigation, trying to avoid the stigma that
still accompanies many patients. Among the activities
organized by the TBS Network are, among
others, the Solidarity Cinema Forum (in prisons,
Cruz Roja premises and NGOs), Informa TB and
Update Days.A pesar de los avances obtenidos en los últimos
años, la tuberculosis sigue siendo un problema relevante
de salud pública en muchas zonas geográficas
del mundo. La tuberculosis es el paradigma de enfermedad
infecciosa con un alto componente social,
y en su abordaje no pueden soslayarse las medidas
tendentes a disminuir la pobreza, las desigualdades
económicas y la integración de los colectivos más
vulnerables. Por ello, la solidaridad y la justicia social
son términos asociados al control de esta enfermedad.
La Red TBS, integrada por diversas instituciones
nacidas de la sociedad civil, intenta informar
a la sociedad y a los profesionales sobre aspectos de
prevención, control, diagnóstico, tratamiento e investigación
de la tuberculosis, intentando evitar el
estigma que acompaña todavía a muchos pacientes.
Entre las actividades que organiza la Red TBS se
encuentran, entre otras, el Cinefórum Solidario (en
prisiones, locales de Cruz Roja y ONGs), Informa

On-the-fly Informed Search of Non-blocking Directed Controllers
We study directed control of discrete event system expressed as the parallel composition of interacting automata. Solutions that first compose the automata and then compute a controller may result in an exponential blow up. We present a technique that builds the composition on-the-fly guided by a novel domain-independent heuristic, which attempts to discover relevant dependencies between the intervening components. We obtain safe and non-blocking directed controllers, or directors, exploring a reduced portion of the state space. We present the first experimental results on directed control comparing on-the-fly composition with informed search against the original monolithic approach to directed control
Supplementary Material for: Predictor Variables of Developing Anterior Pituitary Deficiencies in a Group of Paediatric Patients with Central Diabetes Insipidus and Langerhans Cell Histiocytosis
<p><b><i>Background:</i></b> Langerhans cell histiocytosis (LCH) is a
rare histiocytic disorder of unknown etiopathogenesis. Central diabetes
insipidus (CDI) is the most frequent endocrine manifestation and is a
known risk factor for the development of further anterior pituitary
hormone deficiencies (APD). However, not all CDI patients develop APD,
as observed during prolonged periods of follow-up. <b><i>Aim:</i></b> To find predictors of developing APD in LCH children with CDI followed in our institution. <b><i>Methods:</i></b>
We retrospectively analysed 44 patients over a median period
(quartiles) of 12.3 years (8.79-14.24). Patients were subdivided into
group 1 and group 2, according to absence or presence of APD,
respectively. The main variables studied were: (1) chronological age
(CA) at LCH diagnosis, (2) the primary site of LCH at diagnosis: low
risk (LR) and multisystemic risk organs, and (3) the presence of
reactivation. <b><i>Results:</i></b> Multivariate Cox regression
analysis showed that APD was positively associated with CA at LCH
diagnosis [relative risk (RR) 1.14, <i>p</i> < 0.01], the LR clinical form (RR 8.6, <i>p</i> < 0.03), and negatively associated with the presence of reactivations (RR 0.3, <i>p</i> < 0.01). <b><i>Conclusions:</i></b>
Patients with older CA at LCH diagnosis, LR clinical forms, and fewer
reactivation episodes might represent a subgroup of paediatric LCH CDI
patients with a higher risk of developing APD.</p
Replication of Epigenetic Postpartum Depression Biomarkers and Variation with Hormone Levels
DNA methylation variation at HP / BP3 and TTC9B is modified by estrogen exposure in the rodent hippocampus and was previously shown to be prospectively predictive of postpartum depression (PPD) when modeled in antenatal blood. The objective of this study was to replicate the predictive efficacy of the previously established model in women with and without a previous psychiatric diagnosis and to understand the effects of changing hormone levels on PPD biomarker loci. Using a statistical model trained on DNA methylation data from N = 51 high-risk women, we prospectively predicted PPD status in an independent N = 51 women using first trimester antenatal gene expression levels of HP I BP3 and TTC9B, with an area under the receiver operator characteristic curve (AUC) of 0.81 (95% CI: 0.69-0.92, p<5 x 10(-4)). Modeling DNA methylation of these genes in N = 240 women without a previous psychiatric diagnosis resulted in a cross-sectional prediction of PPD status with an AUC of 0.81 (95% CI: 0.68-0.93, p = 0.01). TTC9B and HP I BP3 DNA methylation at early antenatal time points showed moderate evidence for association to the change in estradiol and allopregnanolone over the course of pregnancy, suggesting that epigenetic variation at these loci may be important for mediating hormonal sensitivity. In addition both loci showed PPD-specific trajectories with age, possibly mediated by age-associated hormonal changes. The data add to the growing body of evidence suggesting that PPD is mediated by differential gene expression and epigenetic sensitivity to pregnancy hormones and that modeling proxies of this sensitivity enable accurate prediction of PPD
High prevalence of BRAF V600E
Targeted therapies with MAPK inhibitors have proven to modulate the clinical manifestations of patients with Langerhans cell histiocytosis (LCH). We explored the presence of BRAFV600E mutation in our cohort of patients with LCH and cholestasis, sclerosing cholangitis, or liver fibrosis that presented resistance to chemotherapy. The BRAFV600E mutation was detected either in the diagnosis (skin and bone) or liver biopsy in our cohort of 13 patients. Thus, we observed a high incidence of BRAFV600E mutation in 100% either in diagnostic biopsy (skin and bone) or liver biopsy in patients with progressive liver disease, sequela, or liver transplant requirement.Fil: Carrere, Xiomara.
