Person-centered medicine (PCM) is a programmatic global initiative led by the International College of Person-Centered Medicine. It has recently emerged in Latin America. It requires the use of scientific research as an instrument to generate the best clinical evidence, and humanism as the essence of medicine to help mankind. It is focused on not only combatting disease but also promoting the display of healthy human being potentials towards achieving well-being and comprehensive growth. Although the humanism of medicine in Latin America has been a distinctive characteristic of its practice, now, there is a worrying decline in its impact on healthcare...

Obstructive Sleep Apnea (OSA) is characterized by partial (hypopnea) or complete cessation (apnea) of airflow to the lungs during sleep. It has been previously reported that apnea episodes lead to significant rise in instantaneous blood pressure concomitant with a rise in cerebral blood flow velocity, indicating loss of cerebral autoregulation during the episodes. In this study, we have used Auto Regressive Moving Average model (ARMA (na, nb, nk)) to quantify OSA induced dynamic changes in cerebral blood flow velocity (CBFV) with beat to beat blood pressure (BP) as an input...

Myelodysplastic syndrome (MDS) is cytogenetically heterogeneous and retains variable risk for acute myeloid leukemia transformation. Though not yet fully understood, there is an association between genetic abnormalities and defects in gene expression. The functional role for infrequent cytogenetic alteration remains unclear. An uncommon chromosomic abnormality is the presence of the Philadelphia (Ph) chromosome. Here, we report a patient with Ph+ MDS treated with low dose Dasatinib who achieved hematologic response for 7 months...

Objectives: Methylation of ribosomal target leads to a high level of resistance towards the entire clinically relevant aminoglycoside antibiotics, so early detection of these resistant determinants will help to reduce the treatment failure as well as will lessen the dissemination rate. Here, we characterize different 16s methyltransferase responsible for aminoglycoside resistance and their epidemiological background in clinical isolates of enterobacteriaceae in a tertiary referral hospital of India.Methods: All aminoglycoside resistant isolates were screened for different 16s methyltransferase by PCR assay and incompatibility typing of the conjugable plasmid harboring resistant genes was determined by PCR based replicon typing...

INTRODUCTION: Immune profile for influenza viruses is highly changeable over time. Serological studies can assess the prevalence of influenza, estimate the risk of infection, highlight asymptomatic infection rate and can also provide data on vaccine coverage. The aims of the study were to evaluate pre-existing cross-protection against influenza A(H3) drift viruses and to assess influenza immunity in the Portuguese population. MATERIALS AND METHODS: We developed a cross-sectional study based on a convenience sample of 626 sera collected during June 2014, covering all age groups, both gender and all administrative health regions of Portugal...

INTRODUCTION: In the context of the evaluation of hospital services, the incorporation of severity indices allows an essential control variable for performance comparisons in time and space through risk adjustment. The severity index for surgical services was developed in 1999 and validated as a general index for surgical services. Sixteen years later the hospital context is different in many ways and a revalidation was considered necessary to guarantee its current usefulness. OBJECTIVE: To evaluate the validity and reliability of the surgical services severity index to warrant its reasonable use under current conditions...

BACKGROUND: CYP24A1 mutations are now accepted as a cause of idiopathic infantile hypercalcemia (IIH). A rapid LC-MS/MS-based blood test enabling measurement of the 25-OH-D3 :24,25-(OH)2 D3 ratio (R) can identify IIH patients on the basis of reduced C24-hydroxylation of 25-OH-D3 by CYP24A1 in vivo. While values of this ratio are significantly elevated in IIH, somewhat surprisingly, serum 24,25-(OH)2 D3 remains detectable. The current study explores possible explanations for this including: residual CYP24A1 enzyme activity in individuals with certain CYP24A1 genotypes, expression of alternative C24-hydroxylases, and the possibility of isobaric contamination of the 24,25-(OH)2 D3 peak on LC-MS/MS...

PM10 forecasting is difficult because of the uncertainties in describing the emission and meteorological fields. This paper proposed a wavelet-ARMA/ARIMA model to forecast the short-time series of the PM10 concentrations. It was evaluated by experiments using a 10-year dataset of daily PM10 concentrations from 4 stations located in Taiyuan, China. The results indicated the following: 1) PM10 concentrations of Taiyuan had a decreasing trend during 2005 to 2012 but it was increased in 2013. PM10 concentrations had an obvious seasonal fluctuation related with coal fired heating in winter and early spring...

The beat-to-beat variability of the QT interval (QTV) is a marker of ventricular repolarization (VR) dynamics and it has been suggested as an index of sympathetic ventricular outflow and cardiac instability. However, QTV is also affected by RR (or heart rate) variability (RRV), and QTV due to RRV may reduce QTV specificity as a VR marker. Therefore, it would be desirable to separate QTV due to VR dynamics from QTV due to RRV. To do that, previous work has mainly focused on heart rate corrections or time-invariant autoregressive models...

Nurse plants promote establishment of other plant species by buffering climate extremes and improving soil properties. Soil biota plays an important role, but an analysis to disentangle the effects of soil microorganisms, soil properties and microclimate on facilitation is lacking. In three microhabitats (gaps, small and large Retama shrubs), we placed six microcosms with sterilized soil, two per soil origin (i.e. from each microhabitat). One in every pair received an alive, and the other a sterile, inoculum from its own soil...

Real-time dynamic displacement and acceleration responses of the main span section of the Tianjin Fumin Bridge in China under ambient excitation were tested using a Global Navigation Satellite System (GNSS) dynamic deformation monitoring system and an acceleration sensor vibration test system. Considering the close relationship between the GNSS multipath errors and measurement environment in combination with the noise reduction characteristics of different filtering algorithms, the researchers proposed an AFEC mixed filtering algorithm, which is an combination of autocorrelation function-based empirical mode decomposition (EMD) and Chebyshev mixed filtering to extract the real vibration displacement of the bridge structure after system error correction and filtering de-noising of signals collected by the GNSS...

Children's blood lead concentrations have been closely monitored over the last two decades in the United States. The bio-monitoring surveillance data collected in local agencies reflected the local temporal trends of children's blood lead levels (BLLs). However, the analysis and modeling of the long-term time series of BLLs have rarely been reported. We attempted to quantify the long-term trends of children's BLLs in the city of Syracuse, New York and evaluate the impacts of local lead poisoning prevention programs and Lead Hazard Control Program on reducing the children's BLLs...
