Treatment of Schizophrenia With Long-Acting Fluphenazine, Haloperidol, or Risperidone
Objective: This study compares 3 cohorts of patients with schizophrenia before, during, and after initiating treatment with fluphenazine decanoate (FD), haloperidol decanoate (HD), or long-acting injectable risperidone (LAR). Methods: Administrative data are analyzed from California Medicaid (Medi-Cal) beneficiaries with schizophrenia who initiated FD, HD, or LAR treatment. Patients were required to have been continuously enrolled in Medi-Cal for 180 days before and 180 days after the start of the new episode of long-acting antipsychotic therapy. Results: There were few demographic and clinical differences among patients initiating FD, HD, and LAR. During the 180 days before starting long-acting injections, most patients initiating FD (53.5%), HD (58.5%), and LAR (61.2%) received oral antipsychotic medications for <80% of the days in this period (medication possession ratio: <0.80). The mean duration of depot treatment episodes was 58.3 days (SD = 53.6) for FD, 71.7 days (SD = 56.4) for HD, and 60.6 days (SD = 48.8) for LAR (F = 18.3, df = 2, 2694, P < .0001, HD > FD). Few patients who started on FD (5.4%), HD (9.7%), or LAR (2.6%) continued for at least 180 days. Most patients in each group (FD [77.4%], HD [78.9%], and LAR [75.5%]) received oral antipsychotic medications during the 45 days after discontinuing long-acting injections. Coprescription with antidepressants, mood stabilizers, and benzodiazepines was common. Conclusions: Patients treated with long-acting antipsychotic injections tend to have complex pharmacological regimens and recent medication nonadherence. A great majority of patients initiating long-acting antipsychotic medications discontinue use within the first few months of treatment
Early Inititation of Breastfeeding and Vitamin a Supplementation with Nutritional Status of Children Aged 6-59 Months
Toddler period, especially the first two years of life is considered as golden age for children because of their rapid growth and development. Therefore, the occurrence of nutritional disorders in the period can be permanent and irreversible. This study tried to assess correlation between early initiation of breastfeeding and vitamin A with nutritional status. The total of samples analyzed in this study was 1,592 toddlers aged 6-59 months that were drawn from 2015 Indonesia Nutritional Status Monitoring Survey in Bengkulu. Data including age, sex, early initiation of breastfeeding, birth length, birth weight, vitamin A supplementation were collected by using questionnaire. Weight and height of children were obtained through anthropometric measurements. More than half of the toddlers (54.6%) did not get early initiation of breastfeeding. Based on multivariate analysis results, most dominant variables related to weight/age, height/age and weight/height indicators were early initiation of breastfeeding and Vitamin A supplementation. Toddlers who did not get early initiation of breastfeeding are at risk of 1.555 times stunting compared to toddlers who got early initiation of breastfeeding. The most dominant variable related to height/age isvitamin A supplementation. Children who do not get vitamin A supplementation are at risk of stunting 2.402 times compared to children who get vitamin A supplementation
Freezing of hard spheres confined in narrow cylindrical pores
Monte Carlo simulations for the equation of state and phase behavior of hard spheres confined inside
very narrow hard tubes are presented. For pores whose radii are greater than 1.1 hard sphere
diameters, a sudden change in the density and the microscopic structure of the fluid is neatly
observed, indicating the onset of freezing. In the high-density structure the particles rearrange in
such a way that groups of three particles fit in sections across the por

Effect of three diets on the gametogenic development and fatty acid profile of Paracentrotus lividus (Lamark, 1816) gonads
Original articleIn this study, the effects of three diets were investigated to enhance Paracentrotus
lividus production for commercial purposes. P. lividus were fed ad libitum for 80 days
with: diet A—fresh Codium tomentosum Stackhouse, 1797; diet B—formulated using
a jellified mix of macroalgae and vegetables, including C. tomentosum (20%), Coralina
sp. Linnaeus, 1758 (17%), cabbage Brassica oleracea var. capitata Linnaeus, 1753
(30%), carrot Daucus carota Linnaeus, 1753 (30%) and agar (3%) as a gelling agent.
Diet C consisted of maize Zea mays Linnaeus, 1753 (56%) and New Zealand spinach
Tetragonia tetragonoides (Pallas, 1781) Kuntze, 1891 (44%). Their effects on the gonadal
and somatic growths, gonadosomatic index (GI) and gametogenesis were evaluated,
as well as on the total lipid content and fatty acid composition of sea urchin's
gonads. Diet A provided high values of eicosapentaenoic acid (EPA). Gonads of sea
urchins fed with diet A were found mostly in growth and maturation stages of gametogenesis
and showed the lowest lipid content. Sea urchins fed with diet B presented
their gonads in the reabsorption stage and had the highest values of omega‐3 polyunsaturated
fatty acids (PUFAs). Sea urchins fed with diet C were in the early stages
of gametogenesis and had the highest values of lipid content, plus omega‐6 PUFAs.
Once as an ingredient in a balanced mix with vegetables, C. tomentosum can be a
key factor to the development of new promising high‐quality and low‐cost feed for

Metabolomics Approaches for the Diagnosis, Treatment, and Better Disease Management of Viral Infections
Metabolomics is an analytical approach that involves profiling and comparing the metabolites present in biological samples. This scoping review article offers an overview of current metabolomics approaches and their utilization in evaluating metabolic changes in biological fluids that occur in response to viral infections. Here, we provide an overview of metabolomics methods including high-throughput analytical chemistry and multivariate data analysis to identify the specific metabolites associated with viral infections. This review also focuses on data interpretation and applications designed to improve our understanding of the pathogenesis of these viral diseases.This research was funded by the Qatar National Research Fund (QNRF), grant number (NPRP11S-1212-170092).Scopu
Evaluation of single and double-locus real-time PCR assays for methicillin-resistant Staphylococcus aureus (MRSA) surveillance
<p>Abstract</p> <p>Background</p> <p>Methicillin-resistant <it>Staphylococcus aureus </it>(MRSA) is a human pathogen, representing an infection control challenge. Conventional MRSA screening takes up to three days, therefore development of rapid detection is essential. Real time-PCR (rt-PCR) is the fastest method fulfilling this task. All currently published or commercially available rt-PCR MRSA assays relay on single or double-locus detection. Double-locus assays are based on simultaneous detection of <it>mecA </it>gene and a <it>S. aureus</it>-specific gene. Such assays cannot be applied on clinical samples, which often contain both coagulase-negative staphylococci (CoNS) and <it>S. aureus</it>, either of which can carry <it>mecA</it>. Single-locus assays are based on detection of the staphylococcal cassette chromosome <it>mec </it>(SCC<it>mec</it>) element and the <it>S. aureus</it>-specific <it>orfX </it>gene, assuming that it is equivalent to <it>mecA </it>detection.</p> <p>Findings</p> <p>Parallel evaluation of several published single and double-locus rt-PCR MRSA assays of 150 pure culture strains, followed by analysis of 460 swab-derived clinical samples which included standard identification, susceptibility testing, followed by PCR detection of staphylococcal suspected isolates and in-PCR mixed bacterial populations analysis indicated the following findings.</p> <p>Pure cultures analysis indicated that one of the single-locus assay had very high prevalence of false positives (Positive predictive value = 77.8%) and was excluded from further analysis. Analysis of 460 swab-derived samples indicated that the second single-locus assay misidentified 16 out of 219 MRSA's and 13 out of 90 methicillin-sensitive <it>S</it>. <it>aureus</it>'s (MSSA) were misidentified as MRSA's. The double-locus detection assay misidentified 55 out of 90 MSSA's. 46 MSSA containing samples were misidentified as MRSA and 9 as other than <it>S. aureus </it>ending with low positive predicted value (<85%) and very low specificity (<62%).</p> <p>Conclusion</p> <p>The results indicate that high prevalence of false-positive and false-negative reactions occurs in such assays.</p
Autoimmune Diseases of the GI Tract Part II: Emergence of Diagnostic Tools and Treatments
Autoimmune diseases (AD) have emerged as a pandemic in our modern societies, especially after the World War II. In part I, we have reviewed five main diseases and shed light on different aspects from introducing the concept of autoimmunity, the description of the disease’s pathogenesis and the diagnosis, the role of antibodies as markers for the prediction of the disease, the link between the gut and brain through what is known as the gut–brain axis, and the relationship of this axis in GI autoimmune diseases. In this chapter, we review the role of antibodies as markers for the prediction of the disease, artificial intelligence in GI autoimmune diseases, the nutritional role and implications in the five GI autoimmune diseases, and finally the treatment of those diseases
5G-enabled Mobile Operating Hospital and Emergency Care Service
Critical care has frequently been fatal for trauma patients suffering from hemorrhage. The pre-hospital communication gap between the paramedics and the doctors contributes most towards this. This paper discusses a system model of a 5G-enabled communication architecture among the major trauma centres in the Greater Manchester. An Internet of sensors acquires and wirelessly communicates biosignals from the patient in real time, using 5G. These signals are then displayed as parameters to the closest trauma care management centres. This paper proposes a connectivity model that supports such a system by assessing and identifying the most optimal path for signal transmittance. A system-level 5G network modelling and simulation findings reveal that a signal-to-noise ratio of over 2dB is achieved for two base stations between the incident site and the nearest emergency medical centre. This value decreases by over 5 dB as the number of base station doubles. Hence, reconfigurable 5G base stations connectivity subsystems are required for critical vertical use cases of the radio standard
PK-guided switch between standard half-life and extended half-life factor VII products
P117
Introduction: Extended half-life (EHL) factor VIII (FVIII) requires improvements in half-life (t1/2) & area under the curve (AUC) of 1.3 & 1.25 times compared to standard half-life (SHL) products. The aim of this study is compare pharmacokinetics (PK) after the switch from SHL to EHL in patients with hemophilia A (HA).
Methods: Multicenter comparative, cross-sectional, prospective study analyzing PK differences after switch from SHL to EHL (ef-moroctocog alfa [rFVIII-Fc] & rurioctocog alfa pegol [PEG-rFVIII]). WAPPS- Hemo® was used to analyze PK parameters with 2-3 samples: t1/2; AUC, peak level (PL); trough level at 24, 48 & 72 hours (TL24, TL48, TL72); & time to reach FVIII levels of 1, 2, 5% (T1%, T2%, T5%). Ratio of t1/2 & AUC, the number of weekly doses & the dose/kg/week before & after the switch were compared. Wilcoxon & Kruskal-Wallis tests (SPSS®) were used to compare the PK parameters.
Results: Eightythree patients from 8 Spanish hospitals were analyzed (62 rFVIII-Fc; 21 PEG-rFVIII), 79 had severe HA & 4 moderate HA. Median age was 30 years (range = 3-64) & no differences in weight were observed between both periods.Dose/kg/week & weekly infusion frequency were reduced after the switch to EHL, & significant improvements were observed in all PK parameters after the change from SHL to EHL (Table 1). The median ratios of t1/2 & AUC were 1.3 (IQR:1.2-1.6) and 1.6 (IQR:1.3-2.2) in the entire cohort. In patients with =12 years ratios of t1/2 & AUC were 1.4 (IQR:1.3-1.6) & 1.7 (IQR:1.3-2.3), and in the cohort of 16 patients <12 years treated with rFVIII-Fc were 1.3 (IQR:0.9-1.5) and 1.4 (IQR:1.1- 2.1).After the switch to EHL, median weekly dose frequency (30%, IQR:0-33.3%) & dose/kg/week (16.9%, IQR:8.7-32.8%) were reduced. In a small subset of 15 younger patients the dose/kg/week was increased a median of 28.6% (IQR:11.7-40-7%). No differences were observed in any of the PK parameters & median ratios of t1/2 & AUC in patients aged =12 years treated with rFVIII-Fc vs. PEG-rFVIII (46 rFVIII-Fc; 21 PEG-rFVIII).
Discussion/Conclusion: EHL FVIII have shown significant PK improvements in clinical real practice, allowing to reduce weekly infusion number & dose/kg/week. Outside the clinical trial setting, we have observed an increase in t1/2 & AUC ratios accordingly to EHL definition. Comparisons regarding clinical outcomes (bleeding rate after switch) will be performed after a follow-up of 1 year with EHL for the full cohort
