Twins prematurity--the influence of prenatal surveillance

OBJECTIVE: To evaluate the influence of the local prenatal surveillance of twin pregnancies in the obstetrical results. METHODS: A prospective cohort study of multiple pregnancies delivered over a period of 16 years in a tertiary centre was conducted. In this study 861 twin pregnancies were included. They were compared for obstetric complications, gestational age at delivery, mode of delivery and birthweight, according to the place of the surveillance. RESULTS: Of the 861 cases examined, the following obstetric complications were significantly different: metrorrhagia (p = 0.039), infections (p < 0.001), HELLP (p = 0.007), PROMPT (p < 0.001) and fetal death (p = 0.024). The mode of delivery was similar but occurred mostly ≤32 weeks (p < 0.001), the birthweight was mostly <2000 g and occurred more NICU admission (p < 0.001) when surveillance was outside the MPC-MDM. CONCLUSION: Our results demonstrate the crucial importance of prenatal surveillance be carried in a differentiated referral centers with specific/strict protocols or the urgent implementation of same protocols in all other places of surveillance, since this straight surveillance greatly reduces the occurrence of prenatal complications, mainly PROMPT, PTD

Monoamniotic twins discordant for body stalk anomaly

Body stalk anomaly is a rare malformation. This anomaly in monozygotic twins is extremely unusual. We describe a case of monoamniotic pregnancy discordant for body stalk anomaly diagnosed at 11 weeks. Ultrasound showed a fetus with a large anterior abdominal wall defect, anomaly of the spine and no evidence of lower extremities and other with a normal morphology. As far as our concern, only three monoamniotic pregnancies discordant for this malformation were reported. Our case represents the fourth reported monoamniotic pregnancy discordant for body stalk anomaly with diagnosis made by ultrasound and the second diagnosed in the first trimester

Control of Pain and Dyspnea in Patients with Oncologic Disease in Acute Care: Non-Pharmacological Intervention

Objective: To identify non-pharmacological strategies in the control of pain and dyspnea, in patient with oncological disease, in acute care. Methodology: Question in PI[C]O format was used and search at EBSCO (MEDLINE with Full TEXT; CINAHL, Plus with Full Text; British Nursing Index) retrospectively from 2009 to 2015. We included also guidelines by reference entities: Oncology Nursing Society (2011) National Comprehensive Cancer Network and Cancer Care Ontario, resulting in a total of 15 articles. Results: The gold standard for an adequate symptom control is a systematized assessment. Non-pharmacological measures: psycho-emotional support, hypnosis, counseling/training/ instruction, therapeutic adherence, music therapy, massage, relaxation techniques, telephone support, functional and respiratory reeducation increase health gains. Conclusion: The control of oncologic pain and dyspnea require a comprehensive and multimodal approach

Evolução dos resultados perinatais em gestações triplas

PURPOSE: To evaluate the obstetric and perinatal outcomes evolution of triplet pregnancies. METHODS: A prospective observational study was conducted in triplet pregnancies delivered over 16 years in a tertiary obstetric center with differentiated perinatal support. Evaluation of demographic factors, obstetric complications, gestational age at delivery, mode of delivery, birth weight and immediate newborn outcome were done over a 16 years period. A global characterization of the sample was performed considering the listed parameters. Variables were categorized in three groups according to year of occurrence: 1996-2000, 2001-2006, 2007-2011, and all parameters were compared. RESULTS: Of the 33 triplets included, 72.7% resulted from induced pregnancies. All except one patient received prenatal corticosteroids and five received tocolytics. All women delivered prenatally and no significant differences were seen in the mean gestational age at delivery or birth weight towards time. There were three intrauterine fetal deaths. Neonatal immediate outcomes were not significantly different over the years. CONCLUSION: Despite remarkable progresses in perinatal and neonatal cares, no noticeable impact in triplet gestations' outcomes was seen, sustaining that triplets should be avoided due to their great risk of prematurity and neonatal morbidities, either by limiting the numbers of embryos transferred or by fetal reduction.info:eu-repo/semantics/publishedVersio

Acute Auditory Stimulation with Different Styles of Music Influences Cardiac Autonomic Regulation in Men

Background: No clear evidence is available in the literature regarding the acute effect of different styles of music on cardiac autonomic control. Objectives: The present study aimed to evaluate the acute effects of classical baroque and heavy metal musical auditory stimulation on Heart Rate Variability (HRV) in healthy men. Patients and Methods: In this study, HRV was analyzed regarding time (SDNN, RMSSD, NN50, and pNN50) and frequency domain (LF, HF, and LF / HF) in 12 healthy men. HRV was recorded at seated rest for 10 minutes. Subsequently, the participants were exposed to classical baroque or heavy metal music for five minutes through an earphone at seated rest. After exposure to the first song, they remained at rest for five minutes and they were again exposed to classical baroque or heavy metal music. The music sequence was random for each individual. Standard statistical methods were used for calculation of means and standard deviations. Besides, ANOVA and Friedman test were used for parametric and non-parametric distributions, respectively. Results: While listening to heavy metal music, SDNN was reduced compared to the baseline (P = 0.023). In addition, the LF index (ms2 and nu) was reduced during exposure to both heavy metal and classical baroque musical auditory stimulation compared to the control condition (P = 0.010 and P = 0.048, respectively). However, the HF index (ms2) was reduced only during auditory stimulation with music heavy metal (P = 0.01). The LF/HF ratio on the other hand decreased during auditory stimulation with classical baroque music (P = 0.019). Conclusions: Acute auditory stimulation with the selected heavy metal musical auditory stimulation decreased the sympathetic and parasympathetic modulation on the heart, while exposure to a selected classical baroque music reduced sympathetic regulation on the heart

Observation of associated near-side and away-side long-range correlations in √sNN=5.02 TeV proton-lead collisions with the ATLAS detector

Two-particle correlations in relative azimuthal angle (Δϕ) and pseudorapidity (Δη) are measured in √sNN=5.02  TeV p+Pb collisions using the ATLAS detector at the LHC. The measurements are performed using approximately 1  μb-1 of data as a function of transverse momentum (pT) and the transverse energy (ΣETPb) summed over 3.1<η<4.9 in the direction of the Pb beam. The correlation function, constructed from charged particles, exhibits a long-range (2<|Δη|<5) “near-side” (Δϕ∼0) correlation that grows rapidly with increasing ΣETPb. A long-range “away-side” (Δϕ∼π) correlation, obtained by subtracting the expected contributions from recoiling dijets and other sources estimated using events with small ΣETPb, is found to match the near-side correlation in magnitude, shape (in Δη and Δϕ) and ΣETPb dependence. The resultant Δϕ correlation is approximately symmetric about π/2, and is consistent with a dominant cos⁡2Δϕ modulation for all ΣETPb ranges and particle pT

Search for new phenomena in final states with an energetic jet and large missing transverse momentum in pp collisions at √ s = 8 TeV with the ATLAS detector

Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb−1 of √ s = 8 TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with pT > 120 GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between Emiss T > 150 GeV and Emiss T > 700 GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with either large extra spatial dimensions, pair production of weakly interacting dark matter candidates, or production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presente

Performance of CMS muon reconstruction in pp collision events at sqrt(s) = 7 TeV

The performance of muon reconstruction, identification, and triggering in CMS has been studied using 40 inverse picobarns of data collected in pp collisions at sqrt(s) = 7 TeV at the LHC in 2010. A few benchmark sets of selection criteria covering a wide range of physics analysis needs have been examined. For all considered selections, the efficiency to reconstruct and identify a muon with a transverse momentum pT larger than a few GeV is above 95% over the whole region of pseudorapidity covered by the CMS muon system, abs(eta) < 2.4, while the probability to misidentify a hadron as a muon is well below 1%. The efficiency to trigger on single muons with pT above a few GeV is higher than 90% over the full eta range, and typically substantially better. The overall momentum scale is measured to a precision of 0.2% with muons from Z decays. The transverse momentum resolution varies from 1% to 6% depending on pseudorapidity for muons with pT below 100 GeV and, using cosmic rays, it is shown to be better than 10% in the central region up to pT = 1 TeV. Observed distributions of all quantities are well reproduced by the Monte Carlo simulation.Comment: Replaced with published version. Added journal reference and DO

Biclustering models for two-mode ordinal data

The work in this paper introduces finite mixture models that can be used to simul- taneously cluster the rows and columns of two-mode ordinal categorical response data, such as those resulting from Likert scale responses. We use the popular proportional odds parameterisation and propose models which provide insights into major patterns in the data. Model-fitting is performed using the EM algorithm and a fuzzy allocation of rows and columns to corresponding clusters is obtained. The clustering ability of the models is evaluated in a simulation study and demonstrated using two real data sets
