Quantifying Uncertainty in Aggregate Queries over Integrated Datasets

Data integration is a notoriously difficult and heuristic-driven process, especially when ground-truth data are not readily available. This paper presents a measure of uncertainty by providing maximal and minimal ranges of a query outcome in two-table, one-to-many data integration workflows. Users can use these query results to guide a search through different matching parameters, similarity metrics, and constraints. Even though there are exponentially many such matchings, we show that in appropriately constrained circumstances that this result range can be calculated in polynomial time with bipartite graph matching. We evaluate this on real-world datasets and synthetic datasets, and find that uncertainty estimates are more robust when a graph-matching based approach is used for data integration

Porównanie urazu tkanek podczas brzusznej, pochwowej i laparoskopowej histerektomii

Objective: The aim of the study was to compare the extent of tissue trauma after abdominal hysterectomy(AH), vaginal hysterectomy (VH), and total laparoscopic hysterectomy (TLH) using biochemical markers. Material and methods: Seventy-one patients requiring hysterectomy for benign uterine diseases were enrolled in the study and divided into three treatment groups: AH (n=24), VH (n=23), and TLH (n=24). Blood samples for assay of interleukin-6 (IL-6) and creatine phosphokinase (CPK) were collected pre-, intra-operatively, and 2, 6 and 24 h after surgery. Results: Serum levels of IL-6, and CPK were significantly elevated over basal values after surgery in all groups. IL-6 and CPK levels were significantly higher after AH as compared to VH and TLH. IL-6 concentrations were significantly higher in the VH group than the TLH group (p=0.001). There were no significant differences in CPK levels between the VH and TLH groups (p=0.824). TLH group had the smallest decrease in blood hemoglobin concentration and the shortest hospital stay. Conclusions: AH causes more tissue trauma as compared to VH and TLH. Owing to the fact that TLH is associated with less tissue trauma and offers significant clinical benefits, including less blood loss and shorter hospital stay, it should be considered in women with benign gynecologic conditions, especially in experienced centers.Cel pracy: Celem badania było porównanie rozległości urazu tkanek podczas brzusznej histerektomii (AH), pochwowej (VH) i laparoskopowej (TLH) przy pomocy biochemicznych markerów. Materiał i metoda: Do badania włączono siedemdziesiąt jeden pacjentek wymagających usunięcia macicy z powodu niezłośliwej patologii, które podzielono na trzy grupy badane: AH (n=24), VH (n=23), i TLH (n=24). Próbki krwi do badania w kierunku interleukiny 6 i kinazy fosfokreatynowej (CPK) pobierano przed-, podczas operacji, I 2,6 oraz 24 godziny po zabiegu. Wyniki: Poziom Il-6 i CPK w surowicy po operacji był istotnie podwyższony w porównaniu do poziomu wyjściowego we wszystkich grupach badanych. Poziom IL-6 i CPK były istotnie wyższe po AH niż po VH i TLH. Stężenie IL-6 było istotnie wyższe w grupie VH niż w grupie TLH (p=0.001). Nie stwierdzono istotnych różnic w poziomie CPK pomiędzy grupą VH i TLH (p=0.824). W grupie TLH odnotowano najmniejszy spadek hemoglobin I najkrótszy pobyt w szpitalu. Wnioski: AH powoduje większy uraz tkanek niż VH i TLH. Dzięki temu, że TLH jest związane z mniejszym urazem tkanek i daje istotne klinicznie korzyści, między innymi mniejszą utratę krwi i krótszy pobyt w szpitalu, powinno być rozważane u kobiet z niezłośliwą patologią, zwłaszcza w doświadczonych ośrodkach

Incisional hernia treatment with polypropylene graft: results of 10 years

Purpose: To report herein our results of tension-free repair of large incisional hernia with polypropylene mesh using a modification of the method that was described by Usher. Method: Two hundred ninety-one patients who were operated on between January 1994 and December 2004 were studied. Two hundred thirty-two patients were female (79.7%), and 59 were male (20.3%). The average follow-up period was 55 months. The patients were evaluated for infection, recurrences, hematoma and seroma formation, sinuses and enterocutaneous fistula formation. Results: Infection was observed in eight patients (2.7%). Graft removal due to infection was encountered only in two patients (0.6%). Recurrence was observed in six patients (2.1%). Two patients (0.6%) developed hematoma while another two developed seroma. No patient developed enterocutaneous fistula. Conclusion: By using our modified technique wecan decrease the expected complications after tension-free repair of large incisional hernias. © Springer-Verlag 2006

Psychiatric Comorbidity in the Subtypes of ADHD in Children and Adolescents with ADHD According to DSM-IV

Introduction: The prevalence rate of psychiatric comorbidity in children and adolescents with Attention Deficit Hyperactivity Disorder (ADHD) was 60-80%. The objective of this study was to examine comorbid disorders associated with ADHD and the subtypes of ADHD in children and adolescents with the diagnosis of ADHD. Method: The study included 326 children and adolescents aged between 8-15 years who were diagnosed with ADHD for the first time as a result of an interview by psychiatry, in a child adolescent psychiatry clinic in Izmir. Sociodemographic form, Turgay DSM-IV Disruptive Behavior Disorders Rating Scale and Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children Present and Lifetime version were used to assess psychiatric comorbidity. Results: The comorbidities accompanied ADHD were disruptive behavior disorder (28.8%), depressive disorder (13.2%), obsessive-compulsive disorder (9.5%) and anxiety disorder (6.1%), in respectively. When the subtypes of ADHD were assessed according to psychiatric comorbidity, oppositional defiant disorder and conduct disorder were frequently seen with ADHD combined type, whereas anxiety disorder was seen more frequent in children diagnosed with ADHD inattentive type. Discussion: Especially the presents of comorbidities in cases with ADHD Combined type increases the severity of disease, causes to retard in responses to treatment and exacerbates prognosis. Therefore, it is very important to determine which psychiatric diagnosis accompany with ADHD

Constraints on the χ_(c1) versus χ_(c2) polarizations in proton-proton collisions at √s = 8 TeV

The polarizations of promptly produced χ_(c1) and χ_(c2) mesons are studied using data collected by the CMS experiment at the LHC, in proton-proton collisions at √s=8  TeV. The χ_c states are reconstructed via their radiative decays χ_c → J/ψγ, with the photons being measured through conversions to e⁺e⁻, which allows the two states to be well resolved. The polarizations are measured in the helicity frame, through the analysis of the χ_(c2) to χ_(c1) yield ratio as a function of the polar or azimuthal angle of the positive muon emitted in the J/ψ → μ⁺μ⁻ decay, in three bins of J/ψ transverse momentum. While no differences are seen between the two states in terms of azimuthal decay angle distributions, they are observed to have significantly different polar anisotropies. The measurement favors a scenario where at least one of the two states is strongly polarized along the helicity quantization axis, in agreement with nonrelativistic quantum chromodynamics predictions. This is the first measurement of significantly polarized quarkonia produced at high transverse momentum
