To evaluate neonatal survival after prolonged preterm premature rupture of membranes (PROM) in the era of antenatal corticosteroids, surfactant, and inhaled nitric oxide. A single-center retrospective cohort study of neonates born from 2002-2011 after prolonged (1 week or more) preterm (less than 24 weeks of gestation) rupture of membranes was performed. The primary outcome was survival to discharge. Neonates whose membranes ruptured less than 24 hours before delivery (n=116) were matched (2:1) on gestational age at birth, sex, and antenatal corticosteroid exposure with neonates whose membranes ruptured 1 week or more before delivery (n=58). Analysis used conditional logistic regression for categorical data and Wilcoxon signed rank test for continuous data. The prolonged preterm PROM exposed and unexposed cohorts had survival rates of 90% and 95%, respectively, although underpowered to assess the statistical significance (P=.313). Exposed neonates were more likely have pulmonary hypoplasia (26/58 exposed, 1/114 unexposed, Prupture (20.4 weeks exposed, 22.3 weeks unexposed, P=.189), length of rupture (3.7 weeks exposed, 6.4 weeks unexposed, P=.717), and lowest maximal vertical pocket before 24 weeks of gestation (0 cm exposed, 1.4 cm unexposed, P=.114) did not discriminate between survivors and nonsurvivors after exposure to prolonged preterm PROM. With antenatal steroid exposure and aggressive pulmonary management, survival to discharge after prolonged preterm PROM was 90%. Pulmonary morbidities were common. Of note, the data were limited to women who remained pregnant 1 week or longer after rupture of membranes.

Introduction With advancing technology it has become possible to accurately record and assess fetal heart rate (FHR) patterns from gestations as early as 20 weeks. The aim of our study was to describe early patterns of FHR, as recorded by transabdominal fetal electrocardiogram according to the Dawes-Redman criteria. Accordingly, short-term variability, basal heart rate, accelerations and decelerations were quantified at 20-24 weeks gestation among women with uncomplicated pregnancies. Methods This study was conducted in a subset of participants enrolled in a large prospective pregnancy cohort study. Our final data set consisted of 281 recordings of women with good perinatal outcomes that had undergone fetal electrocardiographic assessment as part of the Safe Passage Study. Results The success rate of the recordings was 95.4%. The mean frequency of small and large accelerations was 0.5 and 0.1 per 10 minutes respectively and that of small and large decelerations 0.3 and 0.008 per 10 minutes respectively. The mean and basal heart rates were both equal to 148.0 bpm at a median gestation of 161 days. The mean short term variation was 6.2 (SD 1.4) milliseconds and mean minute range 35.1 (SD 7.1) milliseconds. Conclusion The 20 to 24 week fetus demonstrates FHR patterns with more accelerations and decelerations, as well as higher baseline variability than was anticipated. Information from this study provides an important foundation for further, more detailed, studies of early FHR patterns. PMID:23991757

We evaluated the efficacy and safety of tofacitinib in patients with rheumatoid arthritis (RA) in a real-world setting. Seventy consecutive patients, for whom tofacitinib was initiated between November 2013 and May 2016, were enrolled. All patients fulfilled the 2010 ACR/EULAR classification criteria for RA. All patients received 5 mg of tofacitinib twice daily and were followed for 24 weeks. Clinical disease activity indicated by disease activity score (DAS)28-ESR, the simplified disease activity index, and the clinical disease activity index as well as adverse events (AEs) were evaluated. Statistical analysis was performed to determine which baseline variables influenced the efficacy of tofacitinib at 24 weeks. Fifty-eight patients (82.9%) continued tofacitinib at 24 weeks. Clinical disease activity rapidly and significantly decreased, and this efficacy continued throughout the 24 weeks: i.e., DAS28-ESR decreased from 5.04 ± 1.33 at baseline to 3.83 ± 1.11 at 4 weeks and 3.53 ± 1.17 at 24 weeks (Ptofacitinib treatment. The efficacy of tofacitinib was not changed in patients without concomitant use of methotrexate (MTX) or patients whose treatment with tocilizumab (TCZ) failed. Multivariable logistic analysis showed that the number of biologic DMARDs (bDMARDs) previously used was independently associated with achievement of DAS-low disease activity. Our present study suggests that tofacitinib is effective in real-world settings even without concomitant MTX use or after switching from TCZ. Our results also suggest that its efficacy diminishes if started after use of multiple bDMARDs.

Evaluation of biometry is a fundamental step in prenatal brain MR imaging. While different studies have reported reference centiles for MR imaging biometric data of fetuses in the late second and third trimesters of gestation, no one has reported them in fetuses in the early second trimester. We report centiles of normal MR imaging linear biometric data of a large cohort of fetal brains within 24 weeks of gestation. From the data bases of 2 referral centers of fetal medicine, accounting for 3850 examinations, we retrospectively collected 169 prenatal brain MR imaging examinations of singleton pregnancies, between 20 and 24 weeks of gestational age, with normal brain anatomy at MR imaging and normal postnatal neurologic development. To trace the reference centiles, we used the CG-LMS method. Reference biometric centiles for the developing structures of the cerebrum, cerebellum, brain stem, and theca were obtained. The overall interassessor agreement was adequate for all measurements. Reference biometric centiles of the brain structures in fetuses between 20 and 24 weeks of gestational age may be a reliable tool in assessing fetal brain development. © 2018 by American Journal of Neuroradiology.

Magnesium sulphate administration is recommended for foetal neuroprotection in pregnant women at imminent risk of early preterm birth. To evaluate the relationship between intrapartum magnesium sulphate for foetal neuroprotection and delivery room resuscitation of preterm infants less 32 weeks. A prospective observational study was conducted on preterm infants less 32 weeks exposed to magnesium sulphate for neuroprotection, and a comparison made with another historic group immediately before starting this treatment. Cases in both groups that had not reached lung maturity with corticosteroids were rejected. The rates of resuscitation, morbidity and mortality for each of the groups were analysed and compared. There was a total of 107 preterm, with 56 exposed to magnesium sulphate. Rate of advanced resuscitation were similar between the two groups. There were no other differences in mortality, invasive mechanical ventilation, time to first stool, and other comorbidities. Intrapartum magnesium sulphate for foetal neuroprotection was not associated with an increased need for intensive delivery room resuscitation and other morbidities in these cohorts of less than 32 weeks preterm infants.

Elastic scattering 32 S on 24 Mg has been measured at 65.0, 75.0, 86.3, 95.0 and 110.0 MeV-lab energies, and the data were systematically analysed with semi-phenomenological potentials. Using microscopic potentials we found similar results at the lowest incident energies, for which we have compared both the microscopic and semi-phenomenological potentials. It appears that the absorption takes place in a narrow range at the nuclear surface and is mainly due to the low lying collective surface states. (author). 41 refs., 11 figs., 4 tabs

This work evaluates rapid magnetic resonance projection hydrography (PH) based amniotic fluid volume (AFV) estimates against established routine ultrasound single deepest vertical pocket (SDVP) and amniotic fluid index (AFI) measurements, in utero at 28-32 weeks gestation. Manual multi-section planimetry (MSP) based measurement of AFV is used as a proxy reference standard. Thirty-five women with a healthy singleton pregnancy (20-41 years) attending routine antenatal ultrasound were recruited. SDVP and AFI were measured using ultrasound, with same day MRI assessing AFV with PH and MSP. The relationships between the respective techniques were assessed using linear regression analysis and Bland-Altman method comparison statistics. When comparing estimated AFV, a highly significant relationship was observed between PH and the reference standard MSP (R{sup 2} = 0.802, p < 0.001). For the US measurements, SDVP measurement related most closely to amniotic fluid volume, (R{sup 2} = 0.470, p < 0.001), with AFI demonstrating a weaker relationship (R{sup 2} = 0.208, p = 0.007). This study shows that rapid MRI based PH measurement is a better predictor of AFV, relating more closely to our proxy standard than established US techniques. Although larger validation studies across a range of gestational ages are required this approach could form part of MR fetal assessment, particularly where poly- or oligohydramnios is suspected.

The mortality of children with a birthweight of less than 1500g or with a gestational age of less than 32 weeks (<1500<32) has decreased significantly in the last 20 years or so. Given the higher risk of disability in these children, follow-up after hospital discharge is considered essential. In this document, the Follow-Up Group of the Spanish Society of Neonatology, in collaboration with the Spanish Society of Paediatric Primary Care, propose a follow-up protocol specific for the<1500<32, which has as its aim to standardise the activities and evaluations according to good practice criteria.

To achieve the criterion appearance before competing in a physique competition, athletes undergo preparatory regimens involving high-volume intense resistance and aerobic exercise with hypocaloric energy intake. As the popularity of "drug-free" competition increases, more athletes are facing this challenge without the recuperative advantage provided by performance-enhancing drugs. Consequently, the likelihood of loss of lean body and/or bone mass is increased. The purpose of this investigation was to monitor changes in body composition for a 29-year-old self-proclaimed drug-free female figure competitor during a 32-week preparatory regimen comprising high-volume resistance and aerobic exercise with hypocaloric energy intake. We used dual-energy x-ray absorptiometry (DXA) to evaluate regional fat and bone mineral density. During the initial 22 weeks, the subject reduced energy intake and engaged in resistance (4-5 sessions/week) and aerobic (3 sessions/week) training. During the final 10 weeks, the subject increased exercise frequency to 6 (resistance) and 4 (aerobic) sessions/week while ingesting 1130-1380 kcal/day. During this 10-week period, she consumed a high quantity of protein (~55% of energy intake) and nutritional supplements. During the 32 weeks, body mass and fat mass decreased by 12% and 55%, respectively. Conversely, lean body mass increased by 1.5%, an amount that exceeded the coefficient of variation associated with DXA-derived measurement. Total bone mineral density was unchanged throughout. In summary, in preparation for a figure competition, a self-proclaimed drug-free female achieved the low body-fat percentage required for success in competition without losing lean mass or bone density by following a 32-week preparatory exercise and nutritional regimen.

Oral contraceptives may provide a reasonable delivery vehicle for folate supplementation before conception in women of childbearing potential. This study aimed to demonstrate that a fixed-dose combination of an oral contraceptive and levomefolate calcium leads to sustainable improvements in folate status compared with an oral contraceptive + folic acid. Methods: This was a double-blind, randomized, parallel-group study in which 172 healthy women aged 18–40 years received ethinylestradiol (EE-drospirenone-levomefolate calcium or EE-drospirenone + folic acid for 24 weeks (invasion phase, and EE-drospirenone for an additional 20 weeks (folate elimination phase. The main objective of the invasion phase was to examine the area under the folate concentration time-curve for plasma and red blood cell (RBC folate, while the main objective of the elimination phase was to determine the duration of time for which RBC folate concentration remained ≥ 906 nmol/L after cessation of EE-drospirenone-levomefolate calcium. Results: Mean concentration-time curves for plasma folate, RBC folate, and homocysteine were comparable between treatment groups during both study phases. During the invasion phase, plasma and RBC folate concentrations increased and approached steady-state after about 8 weeks (plasma or 24 weeks (RBC. After cessation of treatment with levomefolate calcium, folate concentrations decreased slowly. The median time to RBC folate concentrations falling below 906 nmol/L was 10 weeks (95% confidence interval 8–12 weeks after cessation

Tafenoquine is a promising new 8-aminoquinoline drug that may be useful for malaria prophylaxis in nonpregnant persons with normal glucose-6-phosphate dehydrogenase (G6PD) function. A randomized, double-blind, placebo-controlled chemoprophylaxis trial was conducted with adult residents of northern Ghana to determine the minimum effective weekly dose of tafenoquine for the prevention of infection by Plasmodium falciparum. The primary end point was a positive malaria blood smear result during the 13 weeks of study drug coverage. Relative to the placebo, all 4 tafenoquine dosages demonstrated significant protection against P. falciparum infection: for 25 mg/week, protective efficacy was 32% (95% confidence interval [CI], 20%-43%); for 50 mg/week, 84% (95% CI, 75%-91%); for 100 mg/week, 87% (95% CI, 78%-93%); and for 200 mg/week, 86% (95% CI, 76%-92%). The mefloquine dosage of 250 mg/week also demonstrated significant protection against P. falciparum infection (protective efficacy, 86%; 95% CI, 72%-93%). There was little difference between study groups in the adverse events reported, and there was no evidence of a relationship between tafenoquine dosage and reports of physical complaints or the occurrence of abnormal laboratory parameters. Tafenoquine dosages of 50, 100, and 200 mg/week were safe, well tolerated, and effective against P. falciparum infection in this study population.

Full Text Available Abstract Background In a recently published 24-week maintenance study of olanzapine long-acting injection (LAI in schizophrenia (Kane et al., 2010, apparent dose-associated changes were noted in both efficacy and safety parameters. To help clinicians balance safety and efficacy when choosing a dose of olanzapine LAI, we further studied these changes. Methods Outpatients with schizophrenia who had maintained stability on open-label oral olanzapine for 4 to 8 weeks were randomly assigned to "low" (150 mg/2 weeks; N = 140, "medium" (405 mg/4 weeks; N = 318, or "high" (300 mg/2 weeks; N = 141 dosages of olanzapine LAI for 24 weeks. Potential relationships between dose and several safety or efficacy measures were examined via regression analysis, the Jonckheere-Terpstra test (continuous data, or the Cochran-Armitage test (categorical data.

We studied the effect of antenatal corticosteroids on the incidence of respiratory disorders in singleton neonates born between 34 and 36 weeks of gestation. Retrospective analysis was conducted of the incidence of respiratory distress syndrome (RDS) and other respiratory disorders (need for mechanical ventilation, continuous positive airway pressure, and prolonged oxygen therapy) among singleton neonates delivered between 34 and 36 weeks of gestation who were exposed to antenatal corticosteroids, compared with neonates who were not exposed. Statistical analyses included two-tailed T tests, two-way analysis of variance for continuous data, and chi-square analysis for ratios. A probability of 0.05 was considered significant. Between January 1, 2000, and December 31, 2004, 1078 neonates were born between 34 and 36 weeks of gestation. Information regarding antenatal corticosteroids was available in 1044: 574 neonates (53.2%) were exposed to antenatal corticosteroids and 470 (43.6%) were not. One thousand and eighteen neonates were admitted to the neonatal intensive care unit. Respiratory disorders were diagnosed in 140 of those exposed to antenatal steroids (24.4%) and in 382 of the nonexposed (81.3%) ( P < 0.0001). Two hundred and ten neonates (20.6%) developed RDS: Of those, 43 were exposed to antenatal corticosteroids and 167 were not (incidence of RDS was 7.5% and 35.5%, respectively; P = 0.0001). The beneficial effects of corticosteroids were similar in both genders. It appears that the exposure of singleton pregnancies to antenatal corticosteroids between 24 and 34 weeks of gestation is associated with a significantly lower incidence of respiratory disorders among neonates born at 34 to 36 weeks of gestation. Further studies are needed to determine whether administering antenatal steroids to women experiencing preterm labor after 34 weeks of gestation would be associated with a similar beneficial effect.

One limitation of several recent 24 week Alzheimer's disease (AD) clinical trials was the lack of cognitive decline detected by the AD Assessment Scale-cognitive subscale (ADAS-cog) in the placebo groups, possibly obscuring true medication effects. Data from 733 individuals in the placebo arms of six AD clinical trials performed 1996-1997 were pooled to examine the relationship of clinical, demographic, and genetic characteristics with the 24 week change in ADAS-cog. Baseline cognitive and functional status and the screening-to-baseline change in ADAS-cog were the strongest independent predictors of the 24 week change in ADAS-cog. The ADAS-cog did not detect progression in patients with mild dementia (screening Mini-Mental State Exam, MMSE, >or=20). The change in ADAS-cog from screening to baseline was inversely correlated with the 24 week change score; it was more difficult to detect cognitive decline at 24 weeks if individuals markedly worsened from screening to baseline. The effects of baseline MMSE and screening-to-baseline change in ADAS-cog generalized to the placebo group (N=106) of another AD study performed in 2004-2005. Overcoming lack of placebo decline in AD clinical trials will require scales more sensitive to cognitive decline in mild AD and strategies to reduce within-person variability in outcome measures.

We compared the levels of cell-free human placental lactogen (hPL) messenger RNA (mRNA) in maternal plasma at 28 to 32 weeks of gestation between women with diagnosis of placenta previa or invasive placenta and women with an uneventful pregnancy. Sensitivity and specificity of hPL mRNA for the prediction of invasive placenta were further explored. Plasma hPL mRNA were quantified by real-time reverse-transcriptase polymerase chain reaction in women with placenta previa (n = 13), invasive placenta (n = 5), and normal pregnancies (n = 92). Median (range) hPL mRNA was significantly higher in women with placenta previa, 782 (10-2301) copies/mL of plasma, and in those with invasive placenta, 615 (522-2102) copies/mL of plasma, when compared to normal pregnancies, 90 (4-4407) copies/mL of plasma, P < .01 and P < .05, respectively. We found a sensitivity of 100% and a specificity of 61.5% for the prediction of invasive placenta among women with placenta previa. In conclusion, expression of hPL mRNA is increased in plasma of women with placenta previa and invasive placenta at 28 to 32 weeks of gestation. PMID:23744883

All infants were assessed at corrected ages of 3 and 9 months, using the Alberta Infant Motor Scale. At corrected ages of 4 years, the Movement Assessment Battery for Children was done. Seventy infants were seen at 4 years of age (median of 3 assessments per infant. Abnormal assessment at 3 or 9 months of age resulted in normal outcome in almost 80% at 4 years. On the other hand, a normal outcome in the first year of life resulted in an abnormal outcome at 4 years in 10% of the infants. Our results suggest that long-term followup of these late preterm born infants is necessary, as the assessments in the first year do not predict the long-term outcome.

The radiative proton-capture reactions 19 Ne(p,γ) 20 Na, 23 Mg(p,γ) 24 Al, 27 Si(p,γ) 28 P, 31 S(p,γ) 32 Cl, and 35 Ar(p,γ) 36 K potentially influence energy generation and/or nucleosynthesis during explosive hydrogen burning in classical novae and/or type I x-ray bursts. The thermonuclear rates of these reactions are dependent on resonance energies E r =E x -Q and strengths ωγ. The 20 Ne( 3 He,t) 20 Na, 24 Mg( 3 He,t) 24 Al, 28 Si( 3 He,t) 28 P, 32 S( 3 He,t) 32 Cl, and 36 Ar( 3 He,t) 36 K reactions have been measured using a 32-MeV, 3 He 2+ beam; ion-implanted carbon-foil targets developed at the University of Washington; and the Munich Q3D magnetic spectrograph. This experiment has already yielded precision mass measurements of 20 Na, 24 Al, 28 P, and 32 Cl [C. Wrede et al., Phys. Rev. C 81, 055503 (2010)], which are used presently to constrain the corresponding (p,γ) reaction Q values. The new 24 Al and 28 P masses resolve a discrepancy in the energy of the lowest-energy resonance in the 23 Mg(p,γ) 24 Al reaction and better constrain a direct measurement of its strength. Excitation energies in 32 Cl and 36 K have also been measured. An important new proton-unbound level has been found at E x =2196.9(7) keV in 36 K and the uncertainties in 36 K excitation energies have been reduced by over an order of magnitude. Using the new data on 36 K, the A=36, T=1 triplets have been reassigned. The thermonuclear 35 Ar(p,γ) 36 K reaction rate is found to be much higher than a commonly adopted rate and this could affect energy generation in type I x-ray bursts.

Sarcopenic obesity (SO) is closely associated with cardiovascular disease (CVD) in elderly women. Increases in body fat and decreases in muscle mass are closely associated with increased carotid intima-media thickness (CIMT). The aim of this study was to examine the influence of a 24-week aerobic and resistance training program on carotid parameters in SO. Fifty elderly women (74.1±6.1 years) with SO were randomly divided into an exercise group and a control group. The exercise group performed combined exercise over 24 weeks, consisting of resistance and aerobic training for 50-80 min, 5 times a week. Carotid variables were measured using B-mode ultrasound. The differences in the carotid variables and the relative changes between baseline and after 24 weeks were evaluated. In the analysis of variance (ANOVA) results, CIMT (p=0.013), systolic flow velocity (p=0.007), diastolic flow velocity (p=0.006), and wall shear rate (p=0.010) showed significant interactions. In paired t-test results of the exercise group, CIMT significantly decreased (p＜0.01) and systolic flow velocity (p＜0.01), diastolic flow velocity (p＜0.001), and wall shear rate (p＜0.05) significantly increased after 24 weeks. The 24-week combined exercise effectively decreased CIMT and increased carotid flow velocity and wall shear ratio. Therefore, combined exercise is thought to contribute to the improvement of the risk of CVD in elderly women with SO.

To explore the effects of dual therapy with dapagliflozin and exenatide on body weight, body composition, glycaemic variables and systolic blood pressure (SBP) in obese adults without diabetes. In this single-centre, double-blind trial, we randomized 50 obese adults without diabetes (aged 18-70 years; body mass index 30-45 kg/m 2 ) to oral dapagliflozin 10 mg once daily plus subcutaneous long-acting exenatide 2 mg once weekly or placebo. MRI was used to assess change in body composition. Participants were instructed to follow a balanced diet and exercise moderately. Of 25 dapagliflozin/exenatide- and 25 placebo-treated participants, 23 (92.0%) and 20 (80.0%) completed 24 weeks of treatment, respectively. At baseline, the mean participant age was 52 years, 61% were female, the mean body weight was 104.6 kg, and 73.5% of participants had prediabetes (impaired fasting glucose or impaired glucose tolerance). After 24 weeks, for dapagliflozin/exenatide versus placebo: the difference in body weight change was -4.13 kg (95% confidence interval -6.44, -1.81; P prediabetes was less frequent with active treatment (34.8% vs 85.0%, respectively; P prediabetes and SBP over 24 weeks and was well tolerated in obese adults without diabetes. © 2016 The Authors.

While prednisolone is commonly used to treat recent nerve function impairment (NFI) in leprosy patients, the optimal treatment duration has not yet been established. In this "Treatment of Early Neuropathy in Leprosy" (TENLEP) trial, we evaluated whether a 32-week prednisolone course is more effective than a 20-week course in restoring and improving nerve function. In this multi-centre, triple-blind, randomized controlled trial, leprosy patients who had recently developed clinical NFI (leprosy patients. Twenty weeks is therefore the preferred initial treatment duration for leprosy neuropathy, after which likely only a minority of patients require further individualized treatment.

The medical food Souvenaid, containing the specific nutrient combination Fortasyn Connect, is designed to improve synapse formation and function in patients with Alzheimer's disease (AD). Two double-blind randomized controlled trials (RCT) with Souvenaid of 12 and 24 week duration (Souvenir I and Souvenir II) showed that memory performance was improved in drug-naïve mild AD patients, whereas no effects on cognition were observed in a 24-week RCT (S-Connect) in mild to moderate AD patients using AD medication. Souvenaid was well-tolerated in all RCTs. In this 24-week open-label extension (OLE) study to the 24-week Souvenir II RCT, long-term safety and intake adherence of the medical food Souvenaid was evaluated. Patients with mild AD (n = 201) received Souvenaid once-daily during the OLE. Main outcome parameters were safety and product intake adherence. The memory domain z-score from a revised neuropsychological test battery was continued as exploratory parameter. Compared to the RCT, a similar (low) incidence and type of adverse events was observed, being mainly (68.3%) of mild intensity. Pooled data (RCT and OLE) showed that 48-week use of Souvenaid was well tolerated with high intake adherence (96.1%). Furthermore, a significant increase in the exploratory memory outcome was observed in both the active-active and control-active groups during Souvenaid intervention. Souvenaid use for up to 48-weeks was well tolerated with a favorable safety profile and high intake adherence. The findings in this OLE study warrant further investigation toward the long-term safety and efficacy of Souvenaid in a well-controlled, double-blind RCT.

Meniscus injuries in the United States result in an estimated 850,000 surgical procedures each year. Although meniscectomies are the most commonly performed orthopaedic surgery, little advancement has been made in meniscus replacement and regeneration, and there is currently no total meniscus replacement device approved by the Food and Drug Administration. A novel fiber-reinforced meniscus scaffold can be used as a functional total meniscus replacement. Controlled laboratory study. A tyrosine-derived, polymer fiber-reinforced collagen sponge meniscus scaffold was evaluated mechanically (tensile and compressive testing) and histologically after 16 and 32 weeks of implantation in an ovine total meniscectomy model (N = 20; 16 implants plus 4 meniscectomies, divided equally over the 2 time periods). The extent of cartilage damage was also measured on tibial plateaus by use of toluidine blue surface staining and on femoral condyles by use of Mankin scores on histological slides. Scaffolds induced formation of neomeniscus tissue that remained intact and functional, with breaking loads approximating 250 N at both 16 and 32 weeks compared with 552 N for native menisci. Tensile stiffness values (99 and 74 N/mm at 16 and 32 weeks, respectively) were also comparable with those of the native meniscus (147 N/mm). The compressive modulus of the neomeniscus tissue (0.33 MPa at both 16 and 32 weeks) was significantly increased compared with unimplanted (time 0) scaffolds (0.15 MPa). There was histological evidence of extensive tissue ingrowth and extracellular matrix deposition, with immunohistochemical evidence of types I and II collagen. Based on significantly decreased surface damage scores as well as Mankin scores, the scaffold implants provided greater protection of articular cartilage compared with the untreated total meniscectomy. This novel fiber-reinforced meniscus scaffold can act as a functional meniscus replacement, with mechanical properties similar to those of the

Full Text Available Two-hundred sixteen white laying hens were used to assess the ideal ratio of digestible threonine:lysine in diets for laying hens at 24 to 40 weeks of age. Birds were assigned to a randomized block design, with six treatments, six replicates per treatment and six birds per experimental unit. The cage was used as the blocking criterion. Experimental diets contained different digestible threonine:digestible lysine ratios (65, 70, 75, 80, 85 and 90% with 142 g/kg of crude protein. Experimental diets were formulated to be isonitrogenous and isocaloric with different contents of L-glutamic acid. Feed intake (g/hen/d, egg production (%, egg weight (g, egg mass (g/hen/d, feed conversion ratio (kg/dozen and kg/kg egg, eggshell weight (g, albumen weight (g, yolk weight (g and body weight gain (g were assessed. The maximum egg production was observed at 78% digestible threonine:digestible lysine ratio, while the best values of feed conversion ratio (kg/dozen egg and feed conversion ratio (kg/kg of egg were observed at 77.6% and 75%, respectively. Feed intake, egg mass and egg contents (yolk, albumen and eggshell were not affected by treatments. The estimated digestible threonine:digestible lysine ratio of Hy-Line W36 laying hens at 24 to 40 weeks of age is 78%, corresponding to 5.70 g/kg of dietary digestible threonine.

To investigate the combined effect of diet and orlistat, for 24 weeks, on anthropometric features, hormonal parameters, and indices of insulin resistance in obese women with polycystic ovary syndrome (PCOS) and in obese women without the syndrome. Prospective clinical study. Department of obstetrics and gynecology in a major university in Greece. Eighteen selected women with PCOS were matched for age and body mass index with 14 obese control women. Subjects were prescribed an energy-restricted diet, and orlistat (120 mg, 3 times per d) was administered to all subjects for 24 weeks. At baseline, week 12, and week 24, after an overnight fast, blood samples were collected, and serum levels of FSH, LH, PRL, T, Delta(4)A, DHEAS, 17 alpha-hydroxyprogesterone, sex hormone-binding globulin, glucose, and insulin were measured. Testosterone levels were significantly decreased with treatment in women with PCOS; this decrease was attributed to the first trimester, whereas T levels did not change during the second 12-week period. In women with PCOS, insulin levels and HOMA-IR values were decreased during the first 12 weeks, whereas no significant change was observed during the second trimester. Orlistat administration, combined with diet, for 24 weeks, resulted in significant weight loss and improvement of insulin resistance in obese women, with or without PCOS. Moreover, T levels were significantly decreased in women with PCOS. There appears to be a trend during the first 12-week period for greater improvement of metabolic and hormonal parameters in women with PCOS.

Full Text Available The aim of the study was to investigate the frequency of and the predictors for rehospitalization in preterm infants into early childhood, focusing on gender differences. All preterm infants born at <32 weeks of gestation in North Tyrol between January 2003 and December 2005 were enrolled in this survey. About one fifth of all children were readmitted, showing an inverse downward trend with increasing age. The most common reason for readmission in the third (36.5% and fourth (42.9% years of life was respiratory infection, but changed to miscellaneous surgeries in the fifth (52.1%. Male sex showed significantly higher readmission rates and more miscellaneous surgeries. Additionally, male sex and chronic lung disease were risk conditions for rehospitalization in the multivariate analysis. Readmission rates and respiratory infections in preterm-born children showed an inverse downward trend with increasing age. In early childhood, gender difference still plays a role with regard to rehospitalization.

Spontaneous emission has been used to evaluate the proportion of the different recombination channels in 2.4–3.2 µm type I- GaInAsSb quantum-well lasers operating at room temperature. The method consists in using the square root of the integrated spontaneous emission rate as a value proportional to the carrier density. A second-degree polynomial relationship can then be used to determine the proportion of the different recombination currents (monomolecular, radiative and Auger) in a laser diode operated below threshold. A notable increase of the Auger recombination has been observed with increasing wavelength. Auger recombination currents account for only 26% of the total current at threshold at 2.4 µm, while the proportion reaches 55% at 2.8 µm and 64% at 3.2 µm. (paper)

Frequency, duration and predictors of bronchiolitis episodes of care among infants ≥32 weeks gestation in a large integrated healthcare system: a retrospective cohort study

Directory of Open Access Journals (Sweden)

Flaherman Valerie J

2012-06-01

Full Text Available Abstract Background Bronchiolitis is common in the first two years of life and is the most frequent cause of hospitalization in this age group. No previous studies have used an episode-of-care analysis to describe the frequency, duration, and predictors of bronchiolitis episodes of care during the first two years. Methods We conducted a retrospective cohort study of 123,264 infants ≥32 weeks gestation born at 6 Northern California Kaiser Permanente hospitals between 1996 and 2002. We used electronic medical records to concatenate hospital, emergency department and outpatient health care encounters for bronchiolitis into discrete episodes of care. We used descriptive statistics to report frequency and duration of bronchiolitis episodes and used logistic regression to assess the effect of gestational age and other clinical and demographic predictors on the outcome of bronchiolitis episodes. Results Among all infants, the rate of bronchiolitis episodes was 162 per 1000 children during the first 2 years of life; approximately 40% required >1 day of medical attention with a mean duration of 7.0 ± 5.9 days. Prematurity was associated with increased risk of bronchiolitis episodes and longer duration. Bronchiolitis episodes rates per 1000 infants were 246 for 32–33 weeks gestational age, 204 for 34–36 weeks, and 148–178 for >36 weeks. Male gender, African-American and Hispanic race/ethnicity, and parental history of asthma were associated with an increased risk of having a bronchiolitis episode and/or longer duration. Conclusions Bronchiolitis episodes of care are frequent during the first two years of life and the duration ranges from 1 to 27 days. Prematurity was associated with more frequent and longer duration of bronchiolitis episodes of care, which may reflect illness severity and/or perceived vulnerability.

To assess the efficacy of atomoxetine (ATX) and impact of treatment on family functioning in adults with ADHD. Adults with attention-deficit/hyperactivity disorder (ADHD) having both a spouse/partner and child were randomized to placebo (n = 234) or ATX (n = 268) for 24 weeks. Attention-deficit/hyperactivity disorder measures included the Conners Adult ADHD Rating Scale total ADHD Symptoms score and Clinical Global Impression-ADHD-Severity. Marital measures included the Dyadic Adjustment Scale and the Family Assessment Measure Dyadic Relationship Scale (FAM III). Parenting measures included the Parenting Stress Index, Alabama Parenting Questionnaire, and Parenting Sense of Competence Scale (PSCS). Improvement was greater with ATX over placebo at 24 weeks on the Conners Adult ADHD Rating Scale (-16.43 vs -8.65; P ADHD yielded significant interaction and treatment differences for the FAM III Task Accomplishment and the FAM III and Dyadic Adjustment Scale affective expression items, PSCS total score, Alabama Parenting Questionnaire Corporal Punishment, and Parenting Stress Index attachment items. Atomoxetine demonstrated significant ADHD symptom reduction over 24 weeks. Although both groups demonstrated baseline-to-end point changes on many marital and parenting measure items, there were no treatment differences. Maladaptive behaviors of long-standing ADHD may benefit from both medication and behavioral-psychosocial intervention.

Twenty-nine patients with biopsy-confirmed metastatic melanoma (17) or metastatic renal cell carcinoma (12) were treated with escalating doses or recombinant human interleukin-2 (IL-2) administered as weekly 24-h intravenous infusions. Patients received from 3 to 12 x 10(6) C.U./m2 (18-72 x 10(6) I.U./m2) weekly over a treatment period of 1 to 16 weeks, with a median of eight weekly cycles administered. Patients in all treatment groups experienced non-life-threatening systemic side effects consisting of fever, nausea, vomiting, fluid retention, and diarrhea. Grade III hypotension was seen in four of six patients (67%) at 12 x 10(6) C.U./m2, and represented the dose-limiting toxicity. Grade IV hypotension occurred in 1 of 14 patients at 6 x 10(6) C.U./m2; no other grade IV toxicities were observed. Grade III fever occurred in 3 of 11 patients (27%) treated at 3 x 10(6) C.U./m2, 3 of 14 patients (21%) at 6 x 10(6) C.U./m2, and 3 of 6 patients (50%) at 9 x 10(6) C.U./m2. An objective response was observed in 3 of 28 evaluable patients (10%): 1 complete response and 1 partial response in renal cell cancer, and 1 partial response in a melanoma patient. We conclude that for future studies, the recommended dose of IL-2 given as a weekly 24-h infusion is 9 x 10(6) C.U./m2 and that a low rate of objective tumor response can be obtained in patients with melanoma and renal cell carcinoma using this regimen.

The number and size of free-range laying hen (Gallus gallus domesticus) production systems are increasing within Australia in response to consumer demand for perceived improvement in hen welfare. However, variation in outdoor stocking density has generated consumer dissatisfaction leading to the development of a national information standard on free-range egg labelling by the Australian Consumer Affairs Ministers. The current Australian Model Code of Practice for Domestic Poultry states a guideline of 1500 hens/ha, but no maximum density is set. Radio-frequency identification (RFID) tracking technology was used to measure daily range usage by individual ISA Brown hens housed in six small flocks (150 hens/flock - 50% of hens tagged), each with access to one of three outdoor stocking density treatments (two replicates per treatment: 2000, 10 000, 20 000 hens/ha), from 22 to 26, 27 to 31 and 32 to 36 weeks of age. There was some variation in range usage across the sampling periods and by weeks 32 to 36 individual hens from the lowest stocking density on average used the range for longer each day (Prange with 2% of tagged hens in each treatment never venturing outdoors and a large proportion that accessed the range daily (2000 hens/ha: 80.5%; 10 000 hens/ha: 66.5%; 20 000 hens/ha: 71.4%). On average, 38% to 48% of hens were seen on the range simultaneously and used all available areas of all ranges. These results of experimental-sized flocks have implications for determining optimal outdoor stocking densities for commercial free-range laying hens but further research would be needed to determine the effects of increased range usage on hen welfare.

Full Text Available The aim of this study was to screen neurodevelopmental impairment of preterm twins born at less than 34 weeks of gestation, compare them with the outcome of preterm singletons, and to determine potential neonatal factors adversely related to motor and cognitive outcome. Twins of 25-34 weeks gestation were included in the study. In total, 46 twins were matched with 46 singletons and were followed prospectively to 24 months corrected age. Obstetrical and neonatal data were recorded. All infants were assessed using the Bayley Scales of Infant and Toddler Development III For all morbidities, a significant difference could not be demonstrated. At 24 month follow up there was no significant difference in the cognitive outcome for the twins compared to singletons [98.6 (± 10.4 vs 97.8 (± 9.7, respectively]. There was also no significant difference in the motor outcome for the twins compared to singletons [94.8 (± 12.4 vs 98.1 (± 9.6., respectively]. For the twins, we found a link between pre-eclampsia and abnormal cognitive (p = 0.012 and motor (p = 0.030 results. With the number of twins steadily increasing, close developmental monitoring and probably early intervention services are needed to determine future directions for research.

Radio-frequency identification tracking shows individual free-range laying hens vary in range use, with some never going outdoors. The range is typically more environmentally complex, requiring navigation to return to the indoor resources. Outdoor-preferring hens may have improved spatial abilities compared to indoor-preferring hens. Experiment 1 tested 32 adult ISA Brown hens in a T-maze learning task that showed exclusively-indoor birds were slowest to reach the learning success criterion ( p 0.05), the age that coincided with the onset of lay. Enriched birds that were faster to learn the maze task showed more range visits in the first 4 weeks of range access. Enriched and non-enriched birds showed no differences in telencephalon or hippocampal volume ( p > 0.05). Fear may reduce spatial abilities but further testing with more pen replicates per early rearing treatments would improve our understanding of the relationship between spatial cognitive abilities and range use.

Continuous positive airway pressure (CPAP) is useful in low birth weight infants with respiratory distress, but it is not known if it is a better alternative to mechanical ventilation after early pulmonary surfactant administration. To compare the incidence of adverse events in 28 to 32-week newborns with respiratory distress managed with mechanical ventilation or CPAP after early surfactant administration. In total, 176 newborns were treated with CPAP and 147 with mechanical ventilation, all with Apgar scores >3 at five minutes and without apnea. The incidence of CPAP failure was 6.5% (95% CI: 11.3-22.8%); 29 patients died: 7 with CPAP (4.0%) and 22 with mechanical ventilation (15.0%, pmechanical ventilation was 0.27 (95% CI: 0.12-0.61), but after adjusting for confounding factors, CPAP use did not imply a higher risk of dying (RR=0.60; 95% CI: 0.29-1.24). Mechanical ventilation fatality rate was 5.70 (95% CI: 3.75-8.66) deaths/1,000 days-patient, while with CPAP it was 1.37 (95% CI: 0.65-2.88, pmechanical ventilation (RR=0.71; 95% CI: 0.54-0.96), as were intracranial hemorrhage (RR=0.28, 95% CI: 0.09-0.84) and sepsis (RR=0.67; 95%CI: 0.52-0.86), and it was similar for air leaks (RR=2.51; 95% CI: 0.83-7.61) and necrotizing enterocolitis (RR=1.68, 95% CI: 0.59-4.81). CPAP exposure of premature infants with respiratory distress syndrome is protective against chronic lung disease, intraventricular hemorrhage and sepsis compared to mechanical ventilation. No differences were observed regarding air leak syndrome or death.

Free-range laying hen systems are increasing within Australia. The pullets for these systems are typically reared indoors before being provided first range access around 21 to 26 weeks of age. Thus, the rearing and laying environments are disparate and hens may not adapt well to free-range housing. In this study, we reared 290 Hy-Line® Brown day-old chicks divided into two rooms each with feed, water and litter. In the enriched room, multiple structural, manipulable, visual and auditory stimuli were also provided from 4 to 21 days, the non-enriched room had no additional objects or stimuli. Pullets were transferred to the laying facility at 12 weeks of age and divided into six pens (three enriched-reared, three non-enriched-reared) with identical indoor resources and outdoor range area. All birds were first provided range access at 21 weeks of age. Video observations of natural disturbance behaviours on the range at 22 to 23 and 33 to 34 weeks of age showed no differences in frequency of disturbance occurrences between treatment groups (P=0.09) but a decrease in disturbance occurrences over time (Prange each day (Prange visits than non-enriched birds from 21 to 24 weeks of age (P=0.01). Enriched birds accessed the range on more days (P=0.03) but over time, most birds in both treatment groups accessed the range daily. Basic external health scoring showed minimal differences between treatment groups with most birds in visibly good condition. At 38 weeks of age all birds were locked inside for 2 days and from 40 to 42 weeks of age the outdoor range was reduced to 20% of its original size to simulate stressful events. The eggs from non-enriched birds had higher corticosterone concentrations following lock-in and 2 weeks following range reduction compared with the concentrations within eggs from enriched birds (Prange area reduction compared to non-enriched hens (P=0.02). Only one rearing room per treatment was used but these preliminary data indicate 3 weeks of early

Our aim was to design and evaluate a weight-loss program, including a partial meal replacement program, point-of-care testing and face-to-face and smartphone app support, appropriate for delivery in a community pharmacy setting. Overweight or obese adults (n = 146, 71.2% female, 48.18 ± 11.75 years old) were recruited to participate in a 24-week weight loss study and randomised to two app conditions. The dietary intervention was consistent regardless of app. Twelve weeks of clinic appointments with a trained consultant were followed by only app support for an additional 12 weeks. By week 24, retention was 57.5%. There were no differences between app conditions. Based on a cohort analysis of the trial, the mean decrease in weight from baseline to week 24 was 6.43 ± 1.06 kg for males (p < 0.001) and 5.66 ± 0.70 kg for females (p < 0.001). Mixed models also revealed decreases for LDL Cholesterol (-0.13 ± 0.08 mmol/L, nonsignificant), triglycerides (-0.08 ± 0.05 mmol/L, nonsignificant) and an increase in HDL cholesterol (+0.08 ± 0.04 mmol/L, ns) were not significant by week 24. Blood glucose (-0.23 ± 0.08 mmol/L, p = 0.040) and blood pressure (Systolic blood pressure -5.77 ± 1.21 Hg/mm, p < 0.001) were significantly lower at week 24 compared to baseline. Weight loss self-efficacy increased and remained significantly higher than baseline at week 24 (16.85 ± 2.93, p < 0.001). Overall, the program supported participants and was successful in achieving significant weight loss and improvements in health outcomes over 24 weeks.

Hemophagocytic syndrome is a life-threatening disease characterized by the uncontrolled activation of macrophages, resulting in hemophagocytosis of blood cells in the bone marrow. A 20-year-old gravida at 23-week and 5-day gestation was admitted to hospital to evaluate fever up to 104°F of unknown origin, moderate cytopenia, and elevated levels of liver enzymes. Bone marrow biopsy confirmed hemophagocytic syndrome, and polymerase chain reaction came back positive for Mycobacterium tuberculosis. Supportive care and tuberculosis treatment resulted in clinical improvement. At 27 weeks and 5 days, premature rupture of the membranes occurred, and because of the high probability of reactivating the hemophagocytic syndrome, a cesarean section was performed at 29-week and 2-day gestation. Hemophagocytic syndrome is an uncommon disease which rarely appears during pregnancy. Early diagnosis and treatment can save both maternal and fetal lives.

The authors previously reported on a 2-by-2 randomized clinical trial of individual and combined treatment with atomoxetine (ATX) and parent training (PT) for attention-deficit/hyperactivity disorder (ADHD) symptoms and behavioral noncompliance in 128 5- to 14-year-old children with autism spectrum disorder. In the present report, they describe a 24-week extension of treatment responders and nonresponders. One-hundred seventeen participants from the acute trial (91%) entered the extension; 84 of these were in 2 subgroups: "treatment responders" (n = 43) from all 4 groups in the acute trial, seen monthly for 24 weeks, and "placebo nonresponders" (n = 41), treated with open-label ATX for 10 weeks. Participants originally assigned to PT continued PT during the extension; the remainder served as controls. Primary outcome measurements were the parent-rated Swanson, Nolan and Pelham ADHD scale and the Home Situations Questionnaire. Sixty percent (26 of 43) of treatment responders in the acute trial, including 68% of responders originally assigned to ATX, still met the response criteria at the end of the extension. The response rate of placebo nonresponders treated with 10-week open-label ATX was 37% (15 of 41), similar to the acute trial. Children receiving open-label ATX + PT were significantly more likely to be ADHD responders (53% versus 23%) and noncompliance responders (58% versus 14%) than those receiving open-label ATX alone. Most ATX responders maintained their responses during the extension. PT combined with ATX in the open-label trial appeared to improve ADHD and noncompliance outcomes more than ATX alone.

Androgen deprivation therapy (ADT) for prostate cancer (PCa) impairs musculoskeletal health. We evaluated the efficacy of 32-week football training on bone mineral density (BMD) and physical functioning in men undergoing ADT for PCa. Football training improved the femoral shaft and total hip BMD and physical functioning parameters compared to control. ADT is a mainstay in PCa management. Side effects include decreased bone and muscle strength and increased fracture rates. The purpose of the present study was to evaluate the effects of 32 weeks of football training on BMD, bone turnover markers (BTMs), body composition, and physical functioning in men with PCa undergoing ADT. Men receiving ADT >6 months (n = 57) were randomly allocated to a football training group (FTG) (n = 29) practising 2-3 times per week for 45-60 min or to a standard care control group (CON) (n = 28) for 32 weeks. Outcomes were total hip, femoral shaft, femoral neck and lumbar spine (L2-L4) BMD and systemic BTMs (procollagen type 1 amino-terminal propeptide, osteocalcin, C-terminal telopeptide of type 1 collagen). Additionally, physical functioning (postural balance, jump height, repeated chair rise, stair climbing) was evaluated. Thirty-two-week follow-up measures were obtained for FTG (n = 21) and for CON (n = 20), respectively. Analysis of mean changes from baseline to 32 weeks showed significant differences between FTG and CON in right (0.015 g/cm(2)) and left (0.017 g/cm(2)) total hip and in right (0.018 g/cm(2)) and left (0.024 g/cm(2)) femoral shaft BMD, jump height (1.7 cm) and stair climbing (-0.21 s) all in favour of FTG (p < 0.05). No other significant between-group differences were observed. Compared to standard care, 32 weeks of football training improved BMD at clinically important femoral sites and parameters of physical functioning in men undergoing ADT for PCa.

Full Text Available Abstract Background Growth charts and child growth assessment have become prime global instruments in child health practice over the 30 years. An updated, continuous growth standard that bridges size at birth values with postnatal growth values can improve child growth screening and monitoring. Methods This novel growth chart was constructed from two sources of information. Size at birth (weight, length and head circumference reference values were updated based on information of normal deliveries (i.e. singleton live births without severe congenital malformation, with healthy mothers and born vaginally from the Swedish Medical Birth Registry, 1990–1999 (n = 810393. Weight was evaluated using logarithmic transformation as for postnatal weight. Standard deviations were estimated from data within the empirical mean ± 1.0 SD for each gestational week and gender. These values were smoothed by empirical curve-fitting together with values from our recently published postnatal growth reference including 3650 longitudinally followed children from birth to final height 9. Timescale and weight axes were made logarithmic in order to magnify the early time part of the graph. Results This study presents the first continuous gender specific growth chart from birth irrespective of gestational age at birth until 2 years of age for weight, length and head circumference. Birth weight at 40 weeks of gestation increased approximately 100 gram and length increased only 1 mm compared with earlier Swedish reference from 1977–81. The curve is now less S-shaped as compared with earlier curves and compared with 4 curves from other countries and with more constant variation over the whole range. Conclusion Our values picture the unrestricted pattern of growth improving the detection of a deviating growth pattern, when the growth of an individual infant is plotted on the charts. Especially for very preterm infants age corrected growth can be more easily evaluated

A 2-week ultrasound scanning schedule for monochorionic twins is endorsed widely. There is a lack of robust data to inform a schedule for the surveillance of dichorionic gestations. We aimed to determine how ultrasound scanning that is performed at 2- or 4-week intervals (or every 4 weeks before 32 weeks' gestation and every 2 weeks thereafter) may impact the prenatal detection of fetal growth restriction (FGR) and ultimately influence timing of delivery. In a consecutive cohort of 789 dichorionic twin pregnancies that were recruited prospectively for the multicenter Evaluation of Sonographic Predictors of Restricted Growth in Twins study, ultrasound determination of fetal growth and interrogation of umbilical and middle cerebral artery Doppler scans were performed every 2 weeks from 24 weeks' gestation until delivery. Complete delivery and perinatal outcome data were recorded for all pregnancies. Where delivery was prompted by FGR, abnormal umbilical artery Doppler examination or poor biophysical profile and in the absence of ruptured membranes, onset of labor, preeclampsia, or antepartum hemorrhage, the delivery was considered "ultrasound-indicated." For ultrasound-indicated deliveries, detection probabilities for FGR/abnormal umbilical artery Doppler scans/poor biophysical were determined according to the interval between examinations, by the suppression if alternate examination data. Among 789 dichorionic twin pregnancies, 66 pairs (8%) had an "ultrasound indicated" delivery. Detection of FGR was reduced from 88-69%, and detection of abnormal umbilical artery Doppler was reduced from 82-62% when a 4-week ultrasound schedule was simulated. Both of these reductions reached statistical significance. There was a nonsignificant trend toward a reduction in the recording of oligohydramnios with a 4-week interval between examinations. This study suggests that the ultrasound surveillance program of every 2 weeks that is recommended currently for monochorionic twins

Background: To evaluate the feasibility and clinical preliminary results of weekly cisplatin and volumetric-modulated arc therapy to the pelvis with simultaneous integrated boost to macroscopic disease in a cohort of elderly patients. Materials and Methods: Inclusion criteria of this prospective study were age ≥70 years, Karnofsky performance status 70 to 100, locally advanced histologically proven squamous cervical carcinoma, and patients unable to undergo brachytherapy. Radiation doses prescribed were 66 Gy to the macroscopic disease and 54 Gy to the pelvic nodes in 30 fractions. Weekly cisplatin dose was 40 mg/mq. Results: A total of 30 patients were recruited. Median follow-up was 32 months (range: 8-48 months). Median age was 72 years (range: 70-84 years). The 3-year overall survival and local control were 93% and 80%, respectively. The median time to progression was 24 months (range: 6-30 months). Analyzing clinical outcome grouping based on the stage of disease, II versus III, the 3-year overall survival was 100% and 85%, respectively. The 3-year local control was 91% for stage II and 67% for stage III. Acute and late toxicities were acceptable without severe events. Conclusion: Weekly cisplatin and volumetric-modulated arc therapy–simultaneous integrated boost for radical treatment of advanced cervical cancer in the current cohort of elderly patients were feasible. Long-term results and prospective randomized trials are advocated. PMID:27402633

We have previously shown modest weight loss with vildagliptin treatment. Since body weight balance is associated with changes in blood pressure (BP) and fasting lipids, we have assessed these parameters following vildagliptin treatment. Data were pooled from all double-blind, randomized, controlled, vildagliptin mono-therapy trials on previously drug-naïve patients with type 2 diabetes mellitus who received vildagliptin 50 mg once daily (qd) or twice daily (bid; n=2,108) and wherein BP and fasting lipid data were obtained. Data from patients receiving vildagliptin 50 mg qd or bid showed reductions from baseline to week 24 in systolic BP (from 132.5±0.32 to 129.8±0.34 mmHg; Pvildagliptin shows a significant reduction in BP and a favorable fasting lipid profile that are associated with modest weight loss.

Full Text Available Objective: The aim of this study was to assess the predictive value of uterine artery Doppler imaging at 22-24 weeks of gestation for adverse pregnancy outcomes. Materials and Methods: This was a prospective study in which uterine artery Doppler was performed at 22-24 weeks of gestation in 165 pregnant women with singleton pregnancies. A pulsatility index (PI more than 1.45 or bilateral uterine notching was labeled as abnormal Doppler. The pregnancy outcome was assessed in terms of normal outcome, preeclampsia, fetal growth restriction (FGR, low birth weight, spontaneous preterm delivery, oligohydramnios, fetal loss or at least one adverse outcome. Results: Out of 165 patients, 35 (21.2% had abnormal second trimester uterine artery Doppler. In pregnancies that resulted in preeclampsia (PE, (n=21, FGR, (n=21, and low birth weight (n=39, the median uterine artery PI was higher (1.52, 1.41, and 1.27 respectively. In the presence of abnormal Doppler, the risk of PE [OR=10.7, 95% confidence interval (CI: (3.91-29.1; p<0.001], FGR [OR=4.34, 95% CI: (1.62-11.6; p=0.002], low birth weight [OR=6.39, 95% CI: (3.16-12.9; p<0.001] and the risk of at least one obstetric complication [OR=8.73, 95% CI: (3.5-21.3; p<0.001] was significantly high. The positive predictive value of abnormal uterine artery Doppler was highest for preeclampsia (36.84% among all adverse pregnancy outcomes assessed. Conclusion: Uterine artery Doppler ultrasonography at 22-24 weeks of gestation is a significant predictor of at least one adverse pregnancy outcome, with the highest prediction for preeclampsia.

There is currently no unified policy on either breastfeeding support or enteral nutrition practices, as regards human milk (HM) in pre-term newborns. The aim of this study was to describe breastfeeding support measures, as well as the use of HM in very preterm infants in Spanish public hospitals. A questionnaire on enteral feeding practices was distributed. Data were analysed from units caring for newborns less than 32 weeks or 1,500g. A univariate analysis was performed comparing level ii and iii care units. There was a 91% response rate. A total of 93 units cared for infants less than 32 weeks or 1,500g (17 level ii and 76 level iii), and 49% of the units recorded the breastfeeding rate on discharge. Around 75% (70/93) had a guideline on managing HM (level iii 81 vs. level ii 47%, P=.002), and 25% had access to donor human milk. Just under half (46%) started trophic feeding in the first 6h. Target enteral feeding volume in stable preterm infants was ≥ 180ml/kg/day in 89% of the units (level iii 93% vs. level ii 70%, P =.017). HM fortifier was used in 96% of the units. In 92%, it was added when the required enteral volume was tolerated. In 59% of the units, adjustments in the quantity of fortifier were made according to weight, and in 36%, it depended on analytical criteria. Some units (9%) used pure protein fortifier.

Prader-Willi syndrome (PWS) is a genetic disorder characterized by excessive appetite with progressive obesity and growth hormone (GH) deficiency. Excessive eating causes progressive obesity with increased risk of morbidities and mortality. Although GH treatment has beneficial effects on patients with PWS, adverse events have occurred during GH treatment. Exercise potentially has a positive effect on obesity management. The purpose of this research was to examine the effects of 24-week complex exercise program on changes in body composition, blood lipid profiles, and growth factor hormone levels in a patient with PWS. The case study participant was a 23-year-old man with PWS who also had type II diabetes mellitus because of extreme obesity. Complex exercises, including strength and aerobic exercises, were conducted 5 times one week for 60 minutes per session, over 24 weeks. Blood sampling was conducted five times: before and at 8, 16, 20, and 24 weeks after commencement of the exercise program. Weight, fat mass, triglycerides/high-density lipoprotein (TG/HDL) ratio, mean blood glucose, and GH decreased after training. Blood insulin and insulin-like growth factor (IGF-1) levels increased after training. At 15 and 20 weeks, insulin injection was discontinued. Insulin levels increased and average blood glucose decreased to normal levels; IGF-1 increased continuously during the 24-week exercise program. Conclusion] Twenty-four weeks of complex exercises had a positive effect on obesity and diabetes in the patient with PWS. Therefore, long-period complex exercises might be an effective intervention for improvement of metabolic factors in PWS patients. ©2018 The Korean Society for Exercise Nutrition.

Full Text Available Bochdalek hernia (BH is the most common type of congenital diaphragm hernia and is rarely seen in adults. In adult patients, BH often remains asymptomatic or presents with nondiagnostic symptoms and may lead to complications, though rarely. The necrosis and perforations occurring in the hernia may lead to mortality. In this report, we present a 34-year-old pregnant woman at 24 gestational weeks who presented with Bochdalek hernia causing gastric volvulus associated with perforation and intra-abdominal hemorrhage associated with splenic rupture.

A 6-week, multicenter, randomized, double-masked, parallel-group study comparing travoprost 0.004% to latanoprost 0.005% followed by 6-week, open-label treatment with travoprost 0.004%.

The aim of this study was to compare the tolerability and efficacy of once-daily travoprost 0.004% versus latanoprost 0.005% for 6 weeks followed by 6 weeks of once-daily travoprost 0.004% in decreasing intraocular pressure (IOP) in patients with open-angle glaucoma (OAG) or ocular hypertension (OH). This multicenter, randomized, doublemasked, active-controlled, parallel-group trial was conducted at 32 centers across Latin America. Patients aged > or =18 years with OAG or OH were randomly assigned to receive topical travoprost 0.004% or latanoprost 0.005% 1 drop QD (9 PM) for 6 weeks (masked phase). At 6 weeks, all patients were assigned to receive open-label travoprost 0.004% 1 drop QD (9 PM) for 6 additional weeks (open-label phase). Study visits were scheduled at weeks 1, 2, 4, 6, 8, and 12. At each study visit, IOP was measured at 5 PM (+/-1 hour; approximately 20 hours after study drug administration). IOP changes from baseline were combined (pooled) from the 1-, 2-, 4-, and 6-week data to provide a comparison between the 2 treatment groups. Ocular adverse events (AEs) were monitored using slit-lamp examination. A total of 302 patients were enrolled (travoprost group, 155 patients; latanoprost group, 147 patients). The mean (SD) age of the travoprost group was 61.9 (10.6) years; 60.6% were female; and 47.1% were white. The mean (SD) age of the latanoprost group was 60.5 (12.4) years; 62.6% were female; and 49.0% were white. Mean IOP values were not significantly different between the travoprost and latanoprost groups at baseline (24.7 vs 24.2 mm Hg) or 6 weeks; however, the between-group difference in reductions from baseline in pooled IOP during the masked phase of the study was statistically significant (-8.3 vs -7.5 mm Hg; P = 0.009). At weeks 6 and 12, mean lOP levels were 16.1 and 16.2 mm Hg, respectively, in the travoprost group and 16.4 and 16.1 mm Hg in the group that was switched from latanoprost to travoprost (all, P = NS).

Full Text Available Objective. To assess the effects of regular aerobic training combined with range of motion (ROM exercises on aerobic capacity, quality of life, and function in children with juvenile idiopathic arthritis (JIA. Methods. Thirty patients with JIA and 20 healthy age-matched controls (mean age ± SD, 11.3 ± 2.4 versus 11.0 ± 2.3, resp.; P>0.05 were included. All patients performed aerobic walking (4 days a week for 8 weeks and active and passive ROM exercises of involved joints. All patients completed the childhood health assessment questionnaire (CHAQ and the child health questionnaire. ROM measurements of joints were performed by using universal goniometer. Aerobic capacity was determined by measuring peak oxygen uptake (VO2peak during an incremental treadmill test. Results. Peak oxygen uptake and exercise duration were significantly lower in JIA group than in controls (32.5 ± 6.6 versus 35.9 ± 5.8 and 13.9 ± 1.9 versus 15.0 ± 2.0, resp.; P<0.05 for both. Eight-week combined exercise program significantly improved exercise parameters of JIA patients (baseline versus postexercise VO2peak and exercise duration, 32.5 ± 6.6 to 35.3 ± 7.9 and 13.9 ± 1.9 to 16.3 ± 2.2, resp.; P<0.001 for both. Exercise intervention significantly improved CHAQ scores in JIA patients (0.77 ± 0.61 to 0.20 ± 0.28, P<0.001. Conclusion. We suggest that regular aerobic exercise combined with ROM exercises may be an important part of treatment in patients with JIA.

Patients with advanced gallbladder and biliary tract carcinoma face a dismal prognosis, as no effective palliative chemotherapy exists. The antitumor effect of gemcitabine is schedule-dependent rather than dose-dependent. We evaluated the activity of a prolonged infusion of gemcitabine in advanced gallbladder and biliary tract carcinomas. Nineteen consecutive eligible patients were enrolled. All patients were required to have histologically confirmed diagnosis and measurable disease. Gemcitabine was infused over 24 hours at a dose of 100 mg/m 2 on days 1, 8, and 15. Treatment was repeated every 28 days until progression of disease or limiting toxicity. Tumor response was evaluated every second course by computed tomography (CT) scans. Eighteen patients were evaluable for response. A total of 89 cycles of therapy were administered. One partial response was observed (6%; 95% confidence interval (CI): 0–27%) and ten additional patients had stable disease for at least two months (disease control rate 61%; 95% CI: 36–83%). The therapy was well tolerated, with moderate myelosuppression as the main toxicity. The median time to tumor progression and median overall survival was 3.6 months (95% CI 2.6–4.6 months) and 7.5 months (95% CI 6.5–8.5 months), respectively. Weekly 24-hour gemcitabine at a dose of 100 mg/m 2 is well tolerated. There was a relatively high rate of disease control for a median duration of 5.3 months (range 2.8–18.8 months). However, the objective response rate of this regimen in gallbladder and biliary tract carcinomas was limited

Most studies during pregnancy have assessed maternal left ventricular (LV) function by load-dependent indices, assessing only chamber function. The aim of this study was to assess afterload-adjusted LV myocardial and chamber systolic function at 24 weeks' gestation and 6 months postpartum in high-risk normotensive pregnant women. A group of 118 high-risk women with bilateral notching of the uterine arteries underwent an echocardiographic examination to evaluate midwall mechanics (midwall shortening (mFS%) and stress-corrected midwall shortening (SCmFS%)) of the LV at 24 weeks' gestation and 6 months postpartum. Patients were followed until delivery and pregnancies were classified retrospectively as uneventful (uncomplicated outcome) or complicated. A control group of 54 low-risk women with uneventful pregnancies without bilateral notching was also enrolled. The pregnancy was uneventful in 74 (62.7%) women, whereas 44 (37.3%) developed complications. At 24 weeks' gestation, mFS% and SCmFS% were greater in the uncomplicated-outcome compared with the complicated-outcome group (25.9 ± 4.8 vs 18.8 ± 5.0%, P SCmFS% remained greater in the uncomplicated-outcome compared with the complicated-outcome group (100.4 ± 21.6 vs 87.8 ± 19.1, P SCmFS% was higher during pregnancy than it was postpartum, whereas in the complicated-outcome group, it was lower during pregnancy than it was postpartum (P SCmFS% increased compared with controls) during pregnancy compared with postpartum in high-risk patients with uncomplicated pregnancy, whereas midwall mechanics are depressed both during pregnancy and postpartum in patients with pregnancy complications.

There is limited evidence to guide the selection of second-line anti-hyperglycemic agents in patients with type 2 diabetes mellitus (T2DM) who are inadequately controlled with sulfonylurea monotherapy and are intolerant to metformin. We compared the efficacy and safety of vildagliptin 50 mg qd and Neutral Protamine Hagedorn (NPH) insulin qd in such patients. This was a 24 week, multicenter, randomized, open-label study. The co-primary endpoints were (i) proportion of patients achieving HbA1c vildagliptin (n = 83) and NPH insulin (n = 79). Similar proportion of patients achieved the composite endpoint in vildagliptin versus NPH insulin group (35.4% versus 34.2%; OR 0.985; 95% CI 0.507, 1.915; p = 0.96). After 24 weeks, 48.8% of patients in the vildagliptin group and 60.8% in the NPH insulin group achieved HbA1c vildagliptin group and 29.1% in the insulin group had at least one confirmed HE; while 11.0% in the vildagliptin group and 22.8% in the insulin group experienced weight gain. The rate of confirmed HEs was significantly lower in patients receiving vildagliptin versus NPH insulin (1.3 versus 5.1 events per year). The TSQM-9 score for 'convenience' at week 24 increased significantly more with vildagliptin than with NPH insulin. Addition of vildagliptin and NPH insulin resulted in a similar number of patients reaching HbA1c target without HEs or weight gain in T2DM patients inadequately controlled with sulfonylurea. The addition of vildagliptin to sulfonylurea could be considered as a treatment option prior to intensification with insulin, with the advantages of a lower HE rate and greater patient convenience. Study results are limited by a higher drop-out rate in the vildagliptin arm.

2017-10-01

We aimed to explore the longer-term efficacy and safety of edaravone in an active-treatment extension period following the double-blind period of the second phase III study. Patients who met all the following criteria (scores ≥2 points on all 12 items of the revised amyotrophic lateral sclerosis functional rating scale [ALSFRS-R], forced vital capacity ≥80%, definite or probable ALS, and disease duration ≤2 years) were randomised to 60 mg intravenous edaravone or placebo for six cycles in the double-blind period, and then offered the opportunity to proceed to this 24-week open-label extension period. One hundred and twenty-three of 137 patients continued to the extension period: 65 edaravone-edaravone (E-E group) and 58 placebo-edaravone (P-E group). Change (mean ± standard deviation; SD) in the ALSFRS-R score from baseline in the double-blind period was -4.1 ± 3.4 and -6.9 ± 5.1 in the E-E group and P-E group, respectively, while it was -8.0 ± 5.6 in the E-E group and -10.9 ± 6.9 in the P-E group over the whole 48-week period. The ALSFRS-R score changed almost linearly throughout Cycles 1-12 in the E-E group. The most commonly reported adverse events were constipation, dysphagia, and contusion. There was no sudden deterioration in the ALSFRS-R score of the E-E group. No safety concerns related to edaravone were detected.

Feasibility studies on the production of 32 P and 24 Na using a Miniature Neutron Source Reactor named Ghana Research Reactor-1 (GHARR-1) has been conducted. A theoretical model of the cyclic activation technique was developed for the simulation of specific activities under varying parameters. Specific activity values estimated for four cycles of irradiation with activation parameters falling within the specifications of the reactor were experimentally validated. Experimented results were compared to those theoretically estimated for both 24 Na and 32 P. Experimented specific activity values for both radioisotopes generally fell below their theoretical values but recorded activity build-ups from one cycle to the other. The 24 Na nuclide showed a regular pattern for the increase in specific activity from one cycle to the next with an average percentage difference of experimented to theoretical value of 19%. The 32 P nuclide showed an irregular pattern for the increase in specific activity from one cycle to the next with an average percentage difference of experimental to theoretical value of 11%. The specific activities experimentally attained, with reference to activity levels used for various applications in agriculture and industry suggests the cyclic activation technique can be used for the production of radioisotopes of appreciable activities using low power research reactors, which are characterised with limited excess core reactivity and cannot sustain long periods of irradiation.

To assess the natural history and contemporary outcomes in pregnancies complicated by previable preterm premature rupture of membranes (PROM). Retrospective study of all women with a singleton or twin pregnancy admitted to a single tertiary referral center who experienced preterm PROM between 20 and 23 6/7 weeks of gestation during 2004-2014 and underwent expectant management. Women electing termination of pregnancy and pregnancies complicated by major fetal anomalies were excluded. Severe neonatal morbidity was defined as a composite of bronchopulmonary dysplasia, severe neurologic injury, or severe retinopathy of prematurity. Long-term follow-up to a corrected age of 18-21 months was available for the majority of surviving neonates. Of the 140 neonates born to women with previable preterm PROM during the study period, 104 were eligible for the study. Overall 51 (49.0%, 95% confidence interval [CI] 39.4-58.6%) newborns survived to discharge, of whom 24 (47.1%, 95% CI 33.4-60.8%) experienced severe neonatal morbidity. The overall rate of long-term morbidity among surviving neonates was 23.3% (95% CI 11.7-34.9%) and was significantly higher among neonates who previously experienced severe neonatal morbidity compared with those who did not (39.1% compared with 10.0%, P=.04). The only two factors that were significantly associated with overall survival and survival without severe neonatal morbidity were gestational age at preterm PROM of 22 weeks or greater (adjusted odds ratio [OR] 12.2, 95% CI 3.3-44.8 and adjusted OR 4.8, 95% CI 1.2-19.3, respectively) and a latency period of greater than 7 days (adjusted OR 10.1, 95% CI 3.2-31.6, and adjusted OR 6.7, 95% CI 2.2-21.0, respectively). Expectant management was associated with maternal risks including placental abruption (17.3%, 95% CI 10.0-24.6%) and sepsis (4.8%, 95% CI 0.7-8.9%). Expectant management in pregnancies complicated by previable preterm PROM between 20 and 23 6/7 weeks of gestation is associated with an

Change in weight and body composition was assessed over a six-week holiday period. Baseline testing occurred the Monday or Tuesday prior to Thanksgiving Day (November 24 or 25, 2008), and the post-holiday assessment was the Monday or Tuesday after New Year's Day (January 5 or 6, 2009). Thirteen men and 21 women ranging in age from 23-61 years completed the study. The majority of participants (24 of 34) perceived that they had gained weight, and four did gain ≥2 kg. However, despite some changes to dietary and exercise habits, on average there was no difference between pre-holiday weight (74.0±17.8 kg) and post-holiday weight (73.9±18.1 kg), nor between pre-holiday body fat percentage (25.4±9.0%) and post-holiday body fat percentage (25.4±8.9%). Despite a perception of substantial weight gain, body weight and body fat remained unchanged over a six-week holiday period.

To compare efficacy and safety of various doses of tofacitinib, an oral Janus kinase inhibitor, with placebo in patients with active ankylosing spondylitis (AS, radiographic axial spondyloarthritis). In this 16-week (12-week treatment, 4-week washout), phase II, multicentre, dose-ranging trial, adult patients with active AS were randomised (N=51, 52, 52, 52, respectively) to placebo or tofacitinib 2, 5 or 10 mg twice daily. The primary efficacy endpoint was Assessment of SpondyloArthritis International Society 20% improvement (ASAS20) response rate at week 12. Secondary endpoints included objective measures of disease activity, patient-reported outcomes and MRI of sacroiliac joints and spine. Safety was monitored. Emax model analysis of the primary endpoint predicted a tofacitinib 10 mg twice daily ASAS20 response rate of 67.4%, 27.3% higher than placebo. Supportive normal approximation analysis demonstrated tofacitinib 5 mg twice daily ASAS20 response rate significantly higher than placebo (80.8% vs 41.2%; ptofacitinib 2 and 10 mg twice daily demonstrated greater response rate than placebo (51.9% and 55.8%, respectively; not significant). Secondary endpoints generally demonstrated greater improvements with tofacitinib 5 and 10 mg twice daily than placebo. Objective (including MRI) endpoints demonstrated clear dose response. Adverse events were similar across treatment groups with no unexpected safety findings. Dose-dependent laboratory outcome changes returned close to baseline by week 16. Tofacitinib 5 and 10 mg twice daily demonstrated greater clinical efficacy versus placebo in reducing signs, symptoms and objective endpoints of active AS in adult patients with a similar 12-week safety profile as reported in other indications.

Methods: This 24-week, multicenter, randomized, double-blind, placebo-controlled study evaluated the efficacy, safety and tolerability of the 5-cm2 (9-mg loading dose; 4.6 mg/24 h delivery rate and 10-cm2 (18-mg loading dose; 9.5 mg/24 h delivery rate rivastigmine patch in Japanese patients with AD. Results: In the primary analysis population (intent-to-treat last observation carried forward at week 24, delayed deterioration was seen with the 10-cm2 patch versus placebo on the Japanese version of the Alzheimer’s Disease Assessment Scale-cognitive subscale (ADAS-J cog; p = 0.005 and the Japanese version of the Clinician’s Interview-Based Impression of Change plus Caregiver Input (CIBIC plus-J; p = 0.067. Participants receiving the rivastigmine patch showed numerically less decline versus placebo at week 24 on the CIBIC plus-J, although this did not reach statistical significance. Statistical significance for the CIBIC plus-J was met following adjustment for body weight and baseline Mini-Mental State Examination score as dynamic allocation factors (p = 0.042 and on the Disability Assessment for Dementia (DAD; p = 0.024 and Mental Function Impairment (MENFIS; p = 0.016 subscales. Serious adverse events were rare and were consistent with the known safety profile of the rivastigmine patch. Conclusion: The rivastigmine patch has a favorable efficacy and tolerability profile in Japanese patients with AD.

Conceptual design of a 24--32 MW radially-cooled insert for a ≥45 T hybrid system

The FBNML is designing and will fabricate a radially-cooled insert magnet to generate 70% of the field of a system, Hybrid V, to surpass 45 T in a 32 mm bore. The insert is to have an overall diameter and a maximum active coil length of 610 mm. With a background field of 14 T the system should generate 47 T at 24 MW and nearly 49 T at 32 MW. The peak stress is extremely high, calling for conductors such as Be-Cu (UNS C17510) and 24% Ag-Cu with strengths up to 1,100 MPa. The peak heat flux density also is high, nearly 12 W/mm 2 . Because the water is coldest and its velocity highest where the heat flux is highest, however, the peak temperature is only 80 C. The water flow is ∼ 200 l/s at 27 atm. The system is to be very user friendly. Access is completely unobstructed at the top. Insert removal leaves the plumbing and electrical connections intact. The massive and expensive outer coils should be long lived, the inner coil easily replaceable. During an inner coil burnout, a sleeve intercepts arcing from the inner coil to the middle one, reducing burnout severity and fault loads. The insert should be a worthy successor to those of the FBNML's world-record holding systems, Hybrids II and III

Exploring sexual dimorphism in placental circulation at 22-24 weeks of gestation: A cross-sectional observational study.

Placental blood flow is closely associated with fetal growth and wellbeing. Recent studies suggest that there are differences in blood flow between male and female fetuses. We hypothesized that sexual dimorphism exists in fetal and placental blood flow at 22-24 weeks of gestation. This was a prospective cross-sectional study of 520 healthy pregnant women. Blood flow velocities of the middle cerebral artery (MCA), umbilical artery (UA), umbilical vein (UV) and the uterine arteries (UtA) were measured using Doppler ultrasonography. UV and UtA diameters were measured using two-dimensional ultrasonography and power Doppler angiography. Volume blood flows (Q) of the UV and UtA were calculated. Maternal haemodynamics was assessed with impedance cardiography. UtA resistance (R uta ) was computed as MAP/Q uta . UA PI was significantly (p = 0.008) higher in female fetuses (1.19 ± 0.15) compared with male fetuses (1.15 ± 0.14). MCA PI, cerebro-placental ratio (MCA PI/UA PI), Q uv, UtA PI, Q uta and R uta were not significantly different between groups. At delivery, the mean birth weight and placental weight of female infants (3504 g and 610 g) were significantly (p = 0.0005 and p = 0.039) lower than that of the male infants (3642 g and 634 g). We have demonstrated sexual dimorphism in UA PI, a surrogate for placental vascular resistance, at 22-24 weeks of gestation. Therefore, it would be useful to know when this difference emerges and whether it translates into blood flow differences that may impact upon the fetal growth trajectory.

Full Text Available Objective. To compare the modifications in lipids between patients with rheumatoid arthritis (RA receiving etanercept plus methotrexate (ETA + MTX versus methotrexate (MTX and their relationship with serum levels of tumor necrosis factor-alpha (TNF-α. Methods. In an observational cohort study, we compared changes in lipid levels in patients receiving ETA + MTX versus MTX in RA. These groups were assessed at baseline and at 4 and 24 weeks, measuring clinical outcomes, total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-C, low-density lipoprotein cholesterol, and TNF-α. Results. Baseline values for lipid levels were similar in both groups. HDL-C levels increased significantly only in the ETA + MTX group (from 45.5 to 50.0 mg/dL at 4 weeks, a 10.2% increase, P<0.001, and to 56.0 mg/dL at 24 weeks, a 25.1% increase, P<0.001, while other lipids underwent no significant changes. ETA + MTX also exhibited a significant increase in TNF-α (44.8 pg/mL at baseline versus 281.4 pg/mL at 24 weeks, P<0.001. The MTX group had no significant changes in lipids or TNF-α. Significant differences in HDL-C between groups were observed at 24 weeks (P=0.04 and also in TNF-α  (P=0.01. Conclusion. HDL-C levels increased significantly following treatment with ETA + MTX, without a relationship with decrease of TNF-α.

On the basis of the benefits of frontline radiation in early-stage, extranodal natural killer (NK)/T-cell lymphoma (ENKTL), we conducted the trial of concurrent chemoradiotherapy (CCRT) followed by three cycles of gemcitabine, dexamethasone and cisplatin (GDP). Thirty-two patients with newly diagnosed, stage IE to IIE, nasal ENKTL received CCRT (that is, all patients received intensity-modulated radiotherapy 56 Gy and cisplatin 30 mg/m(2) weekly, 3-5 weeks). Three cycles of GDP (gemcitabine 1000 mg/m(2) intravenously (i.v.) on days 1 and 8, dexamethasone 40 mg orally on days 1-4 and cisplatin 75 mg/m(2) i.v. on day 1 (GDP), every 21 days as an outpatient were scheduled after CCRT. All patients completed CCRT, which resulted in 100% response that included 24 complete responses (CRs) and eight partial responses. The CR rate after CCRT was 75.0% (that is, 24 of 32 responses). Twenty-eight of the 32 patients completed the planned three cycles of GDP, whereas four patients did not because they withdrew (n = 1) or because they had an infection (n = 3). The overall response rate and the CR rate were 90.6% (that is, 29 of 32 responses) and 84.4% (that is, 27 of 32 responses), respectively. Only two patient experienced grade 3 toxicity during CCRT (nausea), whereas 13 of the 30 patients experienced grade 4 neutropenia. The estimated 3-year overall survival and progression-free rates were 87.50% and 84.38%, respectively. In conclusion, CCRT followed by GDP chemotherapy can be a feasible and effective treatment strategy for stage IE to IIE nasal ENKTL.

Full Text Available Abstract Background Studies comparing perinatal outcomes in multiples conceived following the use of artificial reproductive technologies (ART vs. spontaneous conception (SC have reported conflicting results in terms of mortality and morbidity. Therefore, the objective of our study was to compare composite outcome of mortality and severe neonatal morbidities amongst preterm multiple births ≤ 32 weeks gestation infant born following ART vs. SC. Methods We conducted a single center cohort study at Mount Sinai Hospital, Toronto, Ontario, Canada. Data on all preterm multiple births (≤ 32 weeks GA discharged between July 2005 and June 2008 were retrospectively collected from a prospective database at our centre. Details regarding mode of conception were collected retrospectively from maternal health records. Preterm multiple births were categorized into those born following ART vs. SC. Composite outcome was defined as combination of death or any of the three neonatal morbidities (grade 3/4 intraventricular hemorrhage or periventricular leukomalacia; retinopathy of prematurity > stage 2 or chronic lung disease. Univariate and multivariate regression analysis were preformed after adjustment of confounders (maternal age, parity, triplets, gestational age, sex, and small for gestational age. Results One hundred and thirty seven neonates were born following use of ART and 233 following SC. The unadjusted composite outcome rate was significantly higher in preterm multiples born following ART vs. SC [43.1% vs. 26.6%, p = 0.001; OR 1.98 (95% CI 1.13, 3.45]; however, when adjusted for confounders the difference between groups was not statistically significant [OR 1.39, 95% CI 0.67, 2.89]. Conclusion In our population of preterm multiple births, the mode of conception had no detectable effect on the adjusted composite neonatal outcome of mortality and/or three neonatal morbidities.

Methods: Data were pooled from eight clinical monotherapy trials including 2,340 previously drug-naïve patients with type 2 diabetes mellitus who received vildagliptin monotherapy (50 mg once daily [n=359] or 50 mg twice daily [n=1,981]. The trials were all randomized, double-blind, controlled clinical trials with a prespecified week 24 study visit. Results: Linear regression analysis of weight change after 24 weeks relative to baseline FPG showed an intercept of −2.259 kg (95% confidence interval −2.86, −1.66; P<0.0001 and a positive slope of 0.1552 kg (95% confidence interval 0.10–0.21; P<0.0001. Neutral caloric balance (no weight change was observed at a FPG of 14.6 mmol/L (263 mg/dL. Baseline FPG values below and above this threshold were associated with weight loss and weight gain, respectively. For instance, from this analysis, a baseline FPG of 8 mmol/L (144 mg/dL predicts a weight loss of 1 kg. Conclusion: The present analysis showed that treatment with vildagliptin results in a negative caloric balance when glucose levels are below the renal threshold at baseline.

Developmental morphology of the forelimb distal phalanges and lateral palmar processes of 9 Thoroughbred foals aged 3–32 weeks was assessed using radiography, microradiography and histology. For inclusion in the study, all distal phalanges had no pathologic radiographic abnormalities.Vascular channels that are characteristically found in the dorsal region of the distal phalanx were not evident radiographically in the palmar process. The proximal and distal angles of the palmar processes were separated by a lucent line continuous with the incisure in foals only through 12 weeks of age. The distal phalanges were triangular-shaped in foals 3–12 weeks of age, and were oval-shaped in older foals.The palmar aspect of the distal phalanx was the major contributor to growth of the distal phalanx in the sagittal plane, especially between 3 and 12 weeks of age. Growth of the lateral palmar process occurred through the means of endochondral ossification. The body and cortices of the lateral palmar process were composed of coarse cancellous bone. Porosity within the lateral palmar process was greater in regions sampled axial, compared to abaxial, to the parietal sulcus and did not change with age.A fracture was identified microradiographically and/or histologically in 9 of 18 (50%) and 10 of 17 (59%), respectively, of the lateral palmar processes examined. The fracture line was consistently associated with the parietal sulcus on the dorsal cortical surface and was always immediately abaxial to the deep digital flexor tendon attachment. No age-related morphological changes of the lateral palmar processes were identified with microradiography or histological examinations

Background The optimal mode of delivery in twin pregnancies remains controversial. A recent randomized trial did not find any benefit of planned cesarean vs. vaginal delivery at 32–38 weeks gestation, but the trial was not powered to detect a moderate effect. We aimed to evaluate the impact of cesarean delivery on perinatal mortality and severe neonatal morbidity in twin pregnancies at ≥32 weeks through a large database exploration approach with the power to detect moderate risk differences. Methods In a retrospective birth cohort study using the U.S. matched multiple births, 1995–2000 (the available largest multiple birth dataset), we compared perinatal outcomes in twins (n = 181,810 pregnancies) delivered at 32–41 weeks gestation without congenital anomalies. The primary outcome was a composite of perinatal death and severe neonatal morbidity. Cox regression was used to estimate the adjusted hazard ratio (aHR) controlling for the propensity to cesarean delivery, fetal characteristics (sex, birth weight, birth weight discordance, same-sex twin or not) and twin-cluster level dependence. Prospective risks were calculated using the fetuses-at-risk denominators. Results The overall rates of the primary outcome were slightly lower in intended cesarean (6.20%) vs. vaginal (6.45%) deliveries. The aHRs of the primary outcome were in favor of vaginal delivery at 32 (aHR = 1.06, p = 0.03) or 33 (aHR = 1.22, pcesarean delivery at 36 (aHR = 0.94, p = 0.004), 37, 38 and 39+ weeks (aHR: 0.72 to 0.78, all pcesarean vs. vaginal deliveries at 36+ weeks of gestation remained when the analyses were restricted to different-sex (dichorionic) twins (aHR = 0.84, 95% CI 0.80–0.88). Conclusion Cesarean delivery may be beneficial for perinatal outcomes overall in twin pregnancies at ≥36 weeks gestation. PMID:27227678

Background It is widely recognized that the prevalence of obesity and comorbidities including prediabetes and type 2 diabetes continue to increase worldwide. Results from a 24-week Diabetes Prevention Program (DPP) fully mobile pilot intervention were previously published showing promising evidence of the usefulness of DPP-based eHealth interventions on weight loss. Objective This pilot study extends previous findings to evaluate weight loss results of core (up to week 16) and maintenance (postcore weeks) DPP interventions at 65 weeks from baseline. Methods Originally, 140 participants were invited and 43 overweight or obese adult participants with a diagnosis of prediabetes signed up to receive a 24-week virtual DPP with human coaching through a mobile platform. At 65 weeks, this pilot study evaluates weight loss and engagement in maintenance participants by means of repeated measures analysis of variances and backward multiple linear regression to examine predictors of weight loss. Last observation carried forward was used for endpoint measurements. Results At 65 weeks, mean weight loss was 6.15% in starters who read 1 or more lessons per week on 4 or more core weeks, 7.36% in completers who read 9 or more lessons per week on core weeks, and 8.98% in maintenance completers who did any action in postcore weeks (all P<.001). Participants were highly engaged, with 80% (47/59) of the sample completing 9 lessons or more and 69% (32/47) of those completing the maintenance phase. In-app actions related to self-monitoring significantly predicted weight loss. Conclusions In comparison to eHealth programs, this pilot study shows that a fully mobile DPP can produce transformative weight loss. A fully mobile DPP intervention resulted in significant weight loss and high engagement during the maintenance phase, providing evidence for long-term potential as an alternative to in-person DPP by removing many of the barriers associated with in-person and other forms of virtual DPP

This study aimed to evaluate whether selecting mirtazapine as the first choice for current depressive episode instead of selective serotonin reuptake inhibitors (SSRIs) reduces benzodiazepine use in patients with major depressive disorder (MDD). We concurrently examined the relationship between clinical responses and serum mature brain-derived neurotrophic factor (BDNF) and its precursor, proBDNF. We conducted an open-label randomized trial in routine psychiatric practice settings. Seventy-seven MDD outpatients were randomly assigned to the mirtazapine or predetermined SSRIs groups, and investigators arbitrarily selected sertraline or paroxetine. The primary outcome was the proportion of benzodiazepine users at weeks 6, 12, and 24 between the groups. We defined patients showing a ≥50 % reduction in Hamilton depression rating scale (HDRS) scores from baseline as responders. Blood samples were collected at baseline, weeks 6, 12, and 24. Sixty-five patients prescribed benzodiazepines from prescription day 1 were analyzed for the primary outcome. The percentage of benzodiazepine users was significantly lower in the mirtazapine than in the SSRIs group at weeks 6, 12, and 24 (21.4 vs. 81.8 %; 11.1 vs. 85.7 %, both P  depressive episodes may reduce benzodiazepine use in patients with MDD. Trial registration UMIN000004144. Registered 2nd September 2010. The date of enrolment of the first participant to the trial was 24th August 2010. This study was retrospectively registered 9 days after the first participant was enrolled.

Clodronate is a bisphosphonate effective in the prevention and treatment of osteoporosis in postmenopausal women. Non-adherence to bisphosphonates, however, is a major issue in clinical practice. Simplifying dose regimens may increase compliance. To assess bioequivalence between an intramuscular (i.m.) clodronate 200 mg/lidocaine 1% twice-a-month formulation and a clodronate 100 mg/lidocaine 1% weekly formulation in 32 postmenopausal women. In this double-blind, randomized, two-way crossover study, test and reference formulations were administered in single dose, with a 2-week wash-out between administrations. The primary endpoint was clodronic acid cumulative excretion in the first 24 hours after injection (Xu0-24h). Cumulative excretion in the 72 hours post-dose (Xu0-72h) and maximum excretion rate (Ratemax) were also evaluated. Bioequivalence was assumed if the 90% confidence intervals (CIs) of the geometric means ratios of the dose-normalized parameters were within the 80.00 - 125.00% range. Local tolerability was evaluated. Mean Xu0-24h values were 114.03 ±23.13 mg and 55.22 ±9.73 mg for clodronate 200 mg and 100 mg. The 90% CIs for dose-normalized Xu0-24h, Xu0-72h and Ratemax ere 95 -110%, 94 -107% and 95 - 113%. Local tolerability of both treatments was good. The differences in pain intensity between formulations were not sigificantly different at most assessment times. Headache was the only treatment-related adverse event. Bioequivalence of the two formulations was confirmed in terms of dose-normalized rate and amount of clodronic acid excretion. This result, together with the favorable tolerability of the novel 200 mg formulation, suggests the possibility of reducing the number of i.m. administrations from once-a-week to twice-a-month.

Type 2 diabetes (T2D) statistics have reached menacing proportions in India. Appropriate dietary intervention, as part of healthy lifestyle, is imperative to curb further spread of this disease. This pre-post intervention study was conducted in New Delhi, India, to investigate the effects of daily consumption of almonds for 24 weeks in T2D subjects, specifically on measures of glycemia and cardiovascular disease (CVD) risk factors. In this study, the 24-week intervention period was preceded by a control diet and exercise run-in period of 3 weeks. Raw almonds (20% of energy intake) were provided to the patients for consumption along with diet and physical activity counseling. Patients were assessed for anthropometry, blood pressure, measures of glycemia (fasting blood glucose, glycosylated hemoglobin), lipids [total cholesterol (TC), triglycerides, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol, lipoprotein(a)], surrogate marker of atherosclerosis (Pulse wave velocity), and marker of inflammation (high sensitivity C-reactive protein [hs-CRP]) at baseline and after the intervention period. Statistically significant improvement in mean values for various parameters post intervention was as follows: waist circumference (P healthy diet leads to multiple beneficial effects on glycemic and CVDs risk factors in Asian Indian patients with T2D.

Full Text Available Aim: To investigate whether 1-step titration of the rivastigmine patch (initiated at 5 cm2 and titrated to 10 cm2 after 4 weeks is well tolerated in Japanese patients with Alzheimer's disease (AD as compared to 3-step titration (initiated at 2.5 cm2 and titrated by 2.5 cm2 every 4 weeks to 10 cm2. Methods: A 24-week, multicenter, randomized, double-blind study was conducted in Japan between July 2012 and May 2014. Patients with mild to moderate AD aged 50-85 years were randomized 1:1 to 1-step or 3-step titration of the rivastigmine once-daily patch. The primary endpoint was the proportion of patients with adverse events leading to discontinuation. Results: Of 216 patients randomized, 215 (1-step, n = 107; 3-step, n = 108 were included in the safety analysis. The primary endpoint outcome was 15.0% in the 1-step group and 18.5% in the 3-step group. The observed treatment difference was −3.6% (95% confidence interval: −17.0, 9.6, falling within the prespecified acceptance range. Conclusion: The tolerability of two different titration schemes was similar in Japanese patients with AD.

The spin histories of the 3.05-ms pulsar PSR 1821-24 in the globular cluster M28 and the pulsar PSR 1951 + 32 in the supernova remnant C + B80, show that the equation for the minimum possible period for the spin-up by accretion of an accreting magnetized neutron star is not correct. Also the equation should not be considered a 'hard' barrier when considering the magnetic field-period distribution of recycled radio pulsars. The rapid rotation period and period derivative of both pulsars are consistent with both having undergone a previous interval of accretion. (U.K.)

Despite iron supplementation, some preterm infants develop iron deficiency (ID). The optimal iron status parameter for early detection of ID has yet to be determined. To establish reference ranges for reticulocyte haemoglobin content (Ret-He) in preterm and term infants and to identify confounding factors. Retrospective analyses of Ret-He and complete blood count in infants with a clinically indicated blood sample obtained within 24 h after birth. Mean (SD) Ret-He was 30.7 (3.0) pg in very preterm infants with a gestational age (GA) of pH (r = -0.07). There was a slight variation in Ret-He with mode of delivery [normal vaginal delivery: 32.3 (3.2) pg, secondary caesarean section (CS): 31.4 (3.0) pg, instrumental delivery: 31.3 (2.7) pg and elective CS: 31.2 (2.8) pg]. GA at birth has a negligible impact on Ret-He, and the lower limit of the normal reference range in newborns within 24 h after birth can be set to 25 pg. Moreover, Ret-He seems to be a robust parameter which is not influenced by perinatal factors within the first 24 h after birth. © 2016 S. Karger AG, Basel.

Full Text Available Abstract Background The impact of once daily atomoxetine treatment on symptoms in children and adolescents with ADHD may vary over the day. In order to capture such variations, two studies were undertaken in children and adolescents with ADHD using two instruments that capture morning and evening behavior and ADHD-related difficulties over the day. This secondary measure analysis builds on two primary analyses that were conducted separately for children and adolescents and also published separately. Methods In two open-label studies, ADHD patients aged 6–17 years (n = 421, received atomoxetine in the morning (target-dose 0.5–1.2 mg/kg/day for up to 24 weeks. Morning and evening behavior was assessed using the investigator-rated Weekly Rating of Evening and Morning Behavior (WREMB-R scale. ADHD-related difficulties at various times of the day (morning, during school, during homework, evening were assessed using the Global Impression of Perceived Difficulties (GIPD scale, rated by patients, parents and physicians. Data from both studies were combined for this secondary measure analysis. Results Both WREMB-R subscores decreased significantly over time, the evening subscore from 13.7 (95% CI 13.2;14.2 at baseline to 8.0 (7.4;8.5 at week 2, the morning subscore from 4.3 (4.0;4.5 to 2.4 (2.2;2.6. Scores then remained stable until week 24. All GIPD items improved correspondingly. At all times of the day, patients rated ADHD-related difficulties as less severe than parents and physicians. Conclusion These findings from two open-label studies suggest that morning and evening behavior and ADHD-related difficulties in the mornings and evenings improve over time with once daily atomoxetine treatment.

Two sampling methods[SUMMA polished canisters and triple sorbent traps (TSTs)] were compared for long-term storage of trace organic vapor samples collected from the headspaces of high-level radioactive waste tanks at the U.S. Department of Energy's Hanford Site in Washington State. Because safety, quality assurance, radiological controls, the long-term stability of the sampling media during storage needed to be addressed. Samples were analyzed with a gas chromatograph/mass spectrometer (GC/MS) using cryogenic reconcentration or thermal desorption sample introduction techniques. SUMMA canister samples were also analyzed for total non-methane organic compounds (TNMOC) by GC/flame ionization detector (FID) using EPA Compendium Method TO-12 . To verify the long-term stability of the sampling media, multiple samples were collected in parallel from a typical passively ventilated radioactive waste tank known to contain moderately high concentrations of both polar and nonpolar organic compounds. Analyses for organic analytes and TNMOC were conducted at increasing intervals over a 32-week period to determine whether any systematic degradation of sample integrity occurred. Analytes collected in the SUMMA polished canisters generally showed good stability over the full 32 weeks with recoveries at the 80% level or better for all compounds studied. The TST data showed some loss (50-80% recovery) for a few high-volatility compounds even in the refrigerated samples; losses for unrefrigerated samples were far more pronounced with recoveries as low as 20% observed in a few cases

A comprehensive review of accident neutron dosimetry using blood and hair analysis was performed and is summarized in this report. Experiments and calculations were conducted at Oak Ridge National Laboratory (ORNL) and the University of Tennessee (UT) to develop measurement techniques for the activity of 24 Na in blood and 32 P in hair for nuclear accident dosimetry. An operating procedure was established for the measurement of 24 Na in blood using an HPGe detector system. The sensitivity of the measurement for a 20-mL sample is 0.01-0.02 Gy of total neutron dose for hard spectra and below 0.005 Gy for soft spectra based on a 30- to 60-min counting time. The operating procedures for direct counting of hair samples are established using a liquid scintillation detector. Approximately 0.06-0.1 Gy of total neutron dose can be measured from a 1-g hair sample using this procedure. Detailed procedures for chemical dissolution and ashing of hair samples are also developed. A method is proposed to use blood and hair analysis for assessing neutron dose based on a collection of 98 neutron spectra. Ninety-eight blood activity-to-dose conversion factors were calculated. The calculated results for an uncollided fission spectrum compare favorably with previously published data for fission neutrons. This nuclear accident dosimetry system makes it possible to estimate an individual's neutron dose within a few hours after an accident if the accident spectrum can be approximated from one of 98 tabulated neutron spectrum descriptions. If the information on accident and spectrum description is not available, the activity ratio of 32 P in hair and 24 Na in blood can provide information related to the neutron spectrum for dose assessment

Glucagon-like peptide-1 (GLP-1) receptor agonists and sodium-glucose co-transporter-2 (SGLT2) inhibitors improve glycaemic control and reduce bodyweight in patients with type 2 diabetes through different mechanisms. We assessed the safety and efficacy of the addition of the once-weekly GLP-1 receptor agonist dulaglutide to the ongoing treatment regimen in patients whose diabetes is inadequately controlled with SGLT2 inhibitors, with or without metformin. AWARD-10 was a phase 3b, double-blind, parallel-arm, placebo-controlled, 24-week study done at 40 clinical sites in Austria, Czech Republic, Germany, Hungary, Israel, Mexico, Spain, and the USA. Eligible adult patients (≥18 years) with inadequately controlled type 2 diabetes (HbA 1c concentration ≥7·0% [53 mmol/mol] and ≤9·5% [80 mmol/mol]), a BMI of 45 kg/m 2 or less, and taking stable doses (>3 months) of an SGLT2 inhibitor (with or without metformin) were randomly assigned (1:1:1) via an interactive web-response system to subcutaneous injections of either dulaglutide 1·5 mg, dulaglutide 0·75 mg, or placebo once per week for 24 weeks. Patients and investigators were masked to dulaglutide and placebo assignment, and those assessing outcomes were masked to study drug assignment. The primary objective was to test for the superiority of dulaglutide (1·5 mg or 0·75 mg) versus placebo for change in HbA 1c concentration from baseline at 24 weeks. All analyses were done in the intention-to-treat population, defined as all randomly assigned patients who received at least one dose of study drug. This study is registered with ClinicalTrials.gov, number NCT02597049. Between Dec 7, 2015, and Feb 3, 2017, 424 patients were randomly assigned to dulaglutide 1·5 mg (n=142), dulaglutide 0·75 mg (n=142), and placebo (n=140). One patient in the dulaglutide 0·75 mg group was excluded from the analysis because they did not receive any dose of the study drug. The reduction in HbA 1c concentration at 24 weeks was larger

The aim of the research was to study the effects of an insect meal from Hermetia illucens larvae (HILM) as complete replacement of soybean meal (SBM) on productive performance and blood profiles of laying hens, from 24 to 45 wk of age. A total of 108 24-week-old Lohmann Brown Classic laying hens was equally divided into 2 groups (54 hens/group, 9 replicates of 6 hens/group). From 24 to 45 wk of age, the groups were fed 2 different isoproteic and isoenergetic diets: the control group (SBM) was fed a corn-soybean meal based diet, while in the HILM group the soybean meal was completely replaced by Hermetia illucens larvae meal. Feed intake, number of eggs produced, and egg weight were recorded weekly along the trial. At 45 wk of age, blood samples were collected from 2 hens per replicate. The use of HIML led to a more favorable (P meal produced a higher percentage of eggs from small (S), medium (M), and extra-large (XL) classes (P meal, while creatinine was higher (P meal can be a suitable alternative protein source for laying hens even if the complete replacement of soybean meal needs further investigation to avoid the negative effects on feed intake. © 2017 Poultry Science Association Inc.

This study's objective was to determine seasonal and diurnal vs. nocturnal home range size, as well as predation for free-ranging farm cats at a livestock unit in Northwest Georgia. Seven adult cats were tracked with attached GPS units for up to two weeks for one spring and two summer seasons from May 2010 through August 2011. Three and five cats were tracked for up to two weeks during the fall and winter seasons, respectively. Feline scat was collected during this entire period. Cats were fed a commercial cat food daily. There was no seasonal effect (P > 0.05) on overall (95% KDE and 90% KDE) or core home range size (50% KDE). Male cats tended (P = 0.08) to have larger diurnal and nocturnal core home ranges (1.09 ha) compared to female cats (0.64 ha). Reproductively intact cats (n = 2) had larger (P ranges as compared to altered cats. Feline scat processing separated scat into prey parts, and of the 210 feline scats collected during the study, 75.24% contained hair. Of these 158 scat samples, 86 contained non-cat hair and 72 contained only cat hair. Other prey components included fragments of bone in 21.43% of scat and teeth in 12.86% of scat. Teeth were used to identify mammalian prey hunted by these cats, of which the Hispid cotton rat (Sigmodon hispidus) was the primary rodent. Other targeted mammals were Peromyscus sp., Sylvilagus sp. and Microtus sp. Invertebrates and birds were less important as prey, but all mammalian prey identified in this study consisted of native animals. While the free-ranging farm cats in this study did not adjust their home range seasonally, sex and reproductive status did increase diurnal and nocturnal home range size. Ultimately, larger home ranges of free-ranging cats could negatively impact native wildlife.

Effective and efficient treatment is needed for posttraumatic stress disorder (PTSD) in active duty military personnel. To examine the effects of massed prolonged exposure therapy (massed therapy), spaced prolonged exposure therapy (spaced therapy), present-centered therapy (PCT), and a minimal-contact control (MCC) on PTSD severity. Randomized clinical trial conducted at Fort Hood, Texas, from January 2011 through July 2016 and enrolling 370 military personnel with PTSD who had returned from Iraq, Afghanistan, or both. Final follow-up was July 11, 2016. Prolonged exposure therapy, cognitive behavioral therapy involving exposure to trauma memories/reminders, administered as massed therapy (n = 110; 10 sessions over 2 weeks) or spaced therapy (n = 109; 10 sessions over 8 weeks); PCT, a non-trauma-focused therapy involving identifying/discussing daily stressors (n = 107; 10 sessions over 8 weeks); or MCC, telephone calls from therapists (n = 40; once weekly for 4 weeks). Outcomes were assessed before and after treatment and at 2-week, 12-week, and 6-month follow-up. Primary outcome was interviewer-assessed PTSD symptom severity, measured by the PTSD Symptom Scale-Interview (PSS-I; range, 0-51; higher scores indicate greater PTSD severity; MCID, 3.18), used to assess efficacy of massed therapy at 2 weeks posttreatment vs MCC at week 4; noninferiority of massed therapy vs spaced therapy at 2 weeks and 12 weeks posttreatment (noninferiority margin, 50% [2.3 points on PSS-I, with 1-sided α = .05]); and efficacy of spaced therapy vs PCT at posttreatment. Among 370 randomized participants, data were analyzed for 366 (mean age, 32.7 [SD, 7.3] years; 44 women [12.0%]; mean baseline PSS-I score, 25.49 [6.36]), and 216 (59.0%) completed the study. At 2 weeks posttreatment, mean PSS-I score was 17.62 (mean decrease from baseline, 7.13) for massed therapy and 21.41 (mean decrease, 3.43) for MCC (difference in decrease, 3.70 [95% CI,0.72 to 6.68]; P = .02

Full Text Available Abstract Seventy-nine patients underwent bilateral hip arthroplasty staged either at 1 week (Group 1 or after greater intervals (as suggested by the patients, mean 44 weeks, range 16-88 weeks (Group 2, over a five year period at one Institution. Sixty-eight patients (29 bilateral hip resurfacings and 39 total hip replacements completed questionnaires regarding their post-operative recovery, complications and overall satisfaction with the staging of their surgery. There was no significant age or ASA grade difference between the patient groups. Complication rates in the two groups were similar and overall satisfaction rates were 84% in Group 1 (n = 32 and 89% in Group 2 (n = 36. Cumulative hospital lengths of stay were significantly longer in Group 1 patients (11.9 days vs 9.1 days(p The mean time to return to part-time work was 16.4 weeks for Group 1, and a cumulative 17.2 weeks (8.8 and 8.4 weeks for Group 2. The time to return to full-time work was significantly shorter for Group 1 patients (21.0 weeks, compared with a cumulative 29.7 weeks for Group 2(p Hip resurfacing patients in Group 2 had significantly shorter durations of postoperative pain and were able to return to part-time and full time work sooner than total hip arthroplasty patients. There was a general trend towards a faster recovery and resumption of normal activities following the second operation in Group 2 patients, compared with the first operation. Bilateral hip arthroplasty staged at a 1-week interval resulted in an earlier resolution of hip pain, and an earlier return to full-time work (particularly following total hip replacement surgery, with high levels of patient satisfaction and no increased risk in complications; however the hospital length of stay was significantly longer. The decision for the timing of staged bilateral surgery should be made in conjunction with the patient, making adjustments to accommodate their occupational needs and functional demands.

The advent of Amplatzer Duct Occluder II additional Size (ADOIIAS) provided the potential to close hemodynamic significant patent ductus arteriosus (HSPDA) and to analyze the feasibility, safety and efficacy of the device. Treatment of a patent ductus arteriosus (PDA) in very premature neonates is still a dilemma for the neonatalogist who has to consider its significance and has to choose among different treatment options. Because surgical ligation and medical therapy both have their drawbacks, interventional catheterization might provide an alternative means of closing HSPDA. Between September 2013 and June 2015, 32 premature infants with complications related to HSPDA defined by ultrasound (US) underwent transcatheter closure. The procedure was performed in the catheterization laboratory by venous cannulation without angiography. The position of the occluder was directed by X-ray and US. In particular we looked at procedural details, device size selection, complications, and short and mid-term outcomes. Thirty two premature infants, all of whom had clinical complications related to HSPDA, born at gestational ages ranging between 23.6 and 36 weeks (mean ± standard deviation 28 ± 3 weeks) underwent attempted transcatheter PDA closure using the ADOIIAS. Their mean age and weight at the time of procedure was 25 days (range 8-70 days) and 1373 g (range 680-2480 g), respectively. Ten infants weighed ≤1,000g. All ducts were tubular. The mean PDA and device waist diameters were 3.2 ± 0.6mm (range 2.2-4) and 4.4 ± 0.6 mm, respectively, and the mean PDA and device lengths 5.2 ± 2.0 mm (range 2-10) and 3.4 ± 1.3 mm. Median fluoroscopy and procedural times were 11 min (range 3-24) and 28 min (range 10-90), respectively. Complete closure was achieved in all but one patient. There was no device migration. A left pulmonary artery (LPA) obstruction developed in one patient. Five infants died. Four deaths were related to complications of

Objectives To investigate associations between early low neutrophil count from routine blood samples, white blood count (WBC), pregnancy complications and neonatal outcomes for very low birth weight infants (VLBW ≤1500g) with gestational age <32 weeks. Patients and Methods Information was abstracted on all infants admitted to level III NICUs in Wisconsin 2003-2004. 1002 (78%) had differential and corrected total white counts within 2 ½ hours of birth. Data analyses included frequency tables, binary logistic, ordinal logistc and ordinary regression. Results Low neutrophil count (<1000/μL) was strongly associated with low WBC, pregnancy complications and antenatal steroids. Low neutrophil count predicted bronchopulmonary dysplasia severity level (BPD) (OR: 1.7, 95% CI: 1.1-2.7) and intraventricular hemorrhage (IVH) grade (OR: 2.2, 95% CI: 1.3-3.8). Conclusions Early neutrophil counts may have multiple causes interfering with their routine use as an inflammatory marker. Nonetheless, low neutrophil count has consistent independent associations with outcomes. PMID:18563166

The purpose of this investigation was to assess the effectiveness of variable resistance as provided through elastic plus free weight techniques in college aged males and females. Twenty novice lifters were randomly assigned to a traditional free weight only (6 males and 5 females) or elastic band plus free weight group (5 males and 5 females) and 9 more normally active controls (5 males and 4 females), were recruited to maintain normal activity for the duration of the study. No differences existed between control, free weight and elastic band at baseline for age, body height, body mass, body mass index, and body fat percentage. One-repetition maximums were performed for squat and bench press while both strength and power were assessed using isokinetic dynamometry. Elastic groups and free-weight groups completed 24 weeks of whole body, periodized, high intensity resistance (65-95% of one-repetition maximum) training three times/week. Training programs were identical except that the elastic group trained the barbell squat, bench press and stiff-legged deadlift with 20-35% of their total prescribed training loads coming from band resistance (assessed at the top of the range of motion) with the remainder from free weight resistance. A mixed-model analysis revealed that peak torque, average power and one-repetition maximums for squat were significantly greater after training for the elastic group compared to the control (pfree weight group also showed significantly greater improvements over the control in peak torque and one-repetition maximums for squat and bench press. No significant differences were observed between the elastic band and free weight groups. Combined variable elastic band plus free weight exercises are effective at increasing strength and power similar to free-weights alone in novice college aged males and females. However, due to complexity in set-up and load assignment elastic adoption by novice lifters in an unsupervised situation is not advised.

To identify the effectiveness of intravenous paracetamol for closure of patent ductus arteriosus in preterm ≤32 weeks gestation. This was a series of cases, a therapeutic intervention to closure was applied for ductus arteriosus >2 mm, identified by echocardiogram after 3 days of life, intravenous paracetamol was used, for a time range from 3 up to 6 days. The prevalence of patent ductus arteriosus in ≤32 weeks gestation, was 40%. 21 patients were included, there was a predominance of female. Average age at diagnosis was 29 weeks gestation. The minimum weight 750 g, maximum 1350 g. Echocardiogram corroborated closure in 76%, intravenous paracetamol was more successful with 6 days treatment. The prevalence of patent ductus arteriosus is directly proportional to the gestational age, being more common in women. Successful closure was 76%, this drug shows to be as effective as the first-choice drug, and a good alternative for intravenous therapy. Copyright: © 2017 SecretarÍa de Salud

Full Text Available Abstract Background Neurocognitive impairment and psychiatric symptoms have been associated with deficits in psychosocial and occupational functioning in patients with schizophrenia. This post-hoc analysis evaluates the relationships among cognition, psychopathology, and psychosocial functioning in patients with schizophrenia at baseline and following sustained treatment with antipsychotic drugs. Methods Data were obtained from a clinical trial assessing the cognitive effects of selected antipsychotic drugs in patients with schizophrenia. Patients were randomly assigned to 24 weeks of treatment with olanzapine (n = 159, risperidone (n = 158, or haloperidol (n = 97. Psychosocial functioning was assessed with the Heinrichs-Carpenter Quality of Life Scale [QLS], cognition with a standard battery of neurocognitive tests; and psychiatric symptoms with the Positive and Negative Syndrome Scale [PANSS]. A path-analytic approach was used to evaluate the effects of changes in cognitive functioning on subdomains of quality of life, and to determine whether such effects were direct or mediated via changes in psychiatric symptoms. Results At baseline, processing speed affected functioning mainly indirectly via negative symptoms. Positive symptoms also affected functioning at baseline although independent of cognition. At 24 weeks, changes in processing speed affected changes in functioning both directly and indirectly via PANSS negative subscale scores. Positive symptoms no longer contributed to the path-analytic models. Although a consistent relationship was observed between processing speed and the 3 functional domains, variation existed as to whether the paths were direct and/or indirect. Working memory and verbal memory did not significantly contribute to any of the path-analytic models studied. Conclusion Processing speed demonstrated direct and indirect effects via negative symptoms on three domains of functioning as measured by the QLS at baseline and

Full Text Available Arsenic contamination of drinking water is a major public health issue in many countries, increasing risk for a wide array of diseases, including cancer. There is inter-individual variation in arsenic metabolism efficiency and susceptibility to arsenic toxicity; however, the basis of this variation is not well understood. Here, we have performed the first genome-wide association study (GWAS of arsenic-related metabolism and toxicity phenotypes to improve our understanding of the mechanisms by which arsenic affects health. Using data on urinary arsenic metabolite concentrations and approximately 300,000 genome-wide single nucleotide polymorphisms (SNPs for 1,313 arsenic-exposed Bangladeshi individuals, we identified genome-wide significant association signals (P<5×10(-8 for percentages of both monomethylarsonic acid (MMA and dimethylarsinic acid (DMA near the AS3MT gene (arsenite methyltransferase; 10q24.32, with five genetic variants showing independent associations. In a follow-up analysis of 1,085 individuals with arsenic-induced premalignant skin lesions (the classical sign of arsenic toxicity and 1,794 controls, we show that one of these five variants (rs9527 is also associated with skin lesion risk (P = 0.0005. Using a subset of individuals with prospectively measured arsenic (n = 769, we show that rs9527 interacts with arsenic to influence incident skin lesion risk (P = 0.01. Expression quantitative trait locus (eQTL analyses of genome-wide expression data from 950 individual's lymphocyte RNA suggest that several of our lead SNPs represent cis-eQTLs for AS3MT (P = 10(-12 and neighboring gene C10orf32 (P = 10(-44, which are involved in C10orf32-AS3MT read-through transcription. This is the largest and most comprehensive genomic investigation of arsenic metabolism and toxicity to date, the only GWAS of any arsenic-related trait, and the first study to implicate 10q24.32 variants in both arsenic metabolism and arsenical

Full Text Available BackgroundStandard medical treatment for patent ductus arteriosus (PDA closure has been indomethacin/ibuprofen or surgical ligation. Up to date, new strategies have been reported with paracetamol. The aim of this study was to present our experience with intravenous paracetamol for closing PDA in preterm neonates presenting contraindication to ibuprofen or ibuprofen had failed and no candidates for surgical ligation because of huge instability.Materials and methodsWe conducted a retrospective case series study in a neonatal intensive care unit from a tertiary hospital. 9 preterm infants ≤32 weeks of gestational age with hemodynamically significant PDA (hsPDA were enrolled. They received 15 mg/kg/6h intravenous paracetamol for ductal closure. Demographic data and transaminase levels before and after treatment were collected.Results30 preterm babies were diagnosed of hsPDA. 11/30 received ibuprofen with closure in 81.1%. 9 received intravenous paracetamol mainly due to bleeding disorders or thrombocytopenia. Successful closure on paracetamol was achieved in seven of nine babies (77.7%. There was a significant increase in transaminase levels in two patients. They required no treatment for normalization.ConclusionParacetamol is an effective option in closure PDA. It should be a first-line therapeutic option when there are contraindications for ibuprofen treatment. Transaminases must be checked during treatment.

Full Text Available Background: There is no consensus on the treatment of developmental dysplasia of the hip in children less than 24 months of age. The aim of this study was to present the results of open reduction and concomitant primary soft-tissue intervention in patients with developmental dysplasia of the hip in children less than 24 months of age. Materials and Methods: Sixty hips of 50 patients (4 male, 46 female with mean age of 14.62 ± 5.88 (range 5-24 months months with a mean followup of 40.00 ± 6.22 (range 24-58 months months were included. Twenty five right and 35 left hips (10 bilaterally involved were operated. Open reduction was performed using the medial approach in patients aged < 20 months (with Tönnis type II-III and IV hip dysplasias and for those aged 20-24 months with Tönnis type II and III hip dysplasias ( n = 47. However for 13 patients aged 20-24 months with Tönnis type IV hip dysplasias, anterior bikini incision was used. Results: Mean acetabular index was 41.03 ± 3.78° (range 34°-50° in the preoperative period and 22.98 ± 3.01° (range 15°-32° at the final visits. Mean center-edge angle at the final visits was 22.85 ± 3.35° (18°-32°. Based on Severin radiological classification, 29 (48.3% were type I (very good, 25 (41.7% were type II (good and 6 (10% were type III (fair hips. According to the McKay clinical classification, postoperatively the hips were evaluated as excellent ( n = 42; 70%, good ( n = 14; 23.3% and fair ( n = 4; 6.7%. Reduction of all hip dislocations was achieved. Additional pelvic osteotomies were performed in 14 (23.3% hips for continued acetabular dysplasia and recurrent subluxation. (Salter [ n = 12]/Pemberton [ n = 2] osteotomy was performed. Avascular necrosis (AVN developed in 7 (11.7% hips. Conclusion: In DDH only soft-tissue procedures are not enough, because of the high rate of the secondary surgery and AVN for all cases aged less than 24 months. Bone procedures may be necessary in the walking

To determine the real-world safety and effectiveness of iguratimod (IGU) for rheumatoid arthritis (RA), a 52-week, Japanese, post-marketing surveillance study was conducted. An interim analysis at week 24 was performed. This study included all RA patients who received IGU following its introduction to the market. All adverse events (AEs) and adverse drug reactions (ADRs) were collected. Effectiveness was evaluated by the change in Disease Activity Score 28-C-reactive protein (DAS28-CRP) from baseline to week 24. Safety was analyzed in 2679 patients. The overall incidences of AEs, ADRs, and serious ADRs were 38.41, 31.65, and 3.21%, respectively; the most commonly reported serious ADRs were pneumonia/bacterial pneumonia, interstitial lung disease, and Pneumocystis jiroveci pneumonia. Concomitant glucocorticoid use and comorbid conditions associated with respiratory disease were identified as risk factors for serious infections. Pulmonary alveolar hemorrhage and increased international normalized ratio of prothrombin time were observed with concomitant use of IGU and warfarin. The DAS28-CRP decreased from baseline to week 24. Although a safety concern was identified with concomitant use of IGU and warfarin, this real-world study showed no other new safety concerns and similar effectiveness to clinical trials. IGU is a new therapeutic option for RA patients.

Prolonged immobilization reduces passive range of motion of joints creating joint contractures. Whether and to what extent these iatrogenic contractures can be reduced is unknown. We raised three questions using an animal model: What degree of contracture remains at the end of a defined remobilization period? Do contractures in sham-operated and immobilized joints differ? What is the contribution of the posterior knee capsule in limiting knee extension? We immobilized one knee of 11 adult male rats in flexion to induce a joint contracture; 10 control animals underwent a sham operation. After 8 weeks, the internal fixation device was removed, and the animals were allowed to resume unrestricted activity for 4 weeks at the end of which the knee range of motion was measured with standardized torques. The mean flexion contracture was higher in the immobilized group (51.9° ± 2.8°) than in the sham-operated group (18.9° ± 2.1°). Eighty-eight percent of the contractures remained in the immobilized group after dividing skin and muscle, suggesting an important contribution of the posterior knee capsule in limiting knee mobility. Based on our preliminary study the range of motion of rat knees immobilized for 8 weeks remained substantially reduced after a 4-week period of unassisted remobilization. PMID:18299947

To compare neonatal and maternal outcomes in spontaneously onset preterm breech deliveries after trial of labor (BTOL) and intended cesarean section (BCS), and between BTOL and vertex control deliveries, in singleton fetuses at 32 +0 -36 +6  weeks of gestation. Retrospective single center cohort study in a Finnish University Hospital including all spontaneous-onset preterm breech deliveries with 32 completed gestational weeks in 2003-2015. The study population comprised a total of 176 preterm breech and 103 vertex control deliveries, matched by gestational age and whether the mother had given birth vaginally before or not. Infants with severe malformations and antepartum fetal distress were excluded. Subgroup analyses were made in two cohorts according to gestational age. Main outcome measures were maternal and neonatal mortality and morbidity, low cord pH and Apgar score. No mortality was observed, and severe morbidity was rare. No difference in incidence of low cord pH or five-minute Apgar score was observed between the groups. Apgar scores at the age of one minute were comparable in the breech groups but more often low in the BTOL group compared to the vertex control group. 16.5% of neonates in the BTOL group, 23.3% in the BCS group and 7.8% in the vertex group needed intensive care. In logistic regression analysis, lower gestational age and being small for gestational age were associated with the need for neonatal intensive care. Being allowed a trial of labor was not associated with the need for neonatal intensive care. Maternal morbidity was similar across the groups, but median blood loss was more pronounced in the BCS group compared to the BTOL group. In breech deliveries at 32 +0 -36 +6 gestational weeks, trial of labor did not increase neonatal morbidity compared to intended cesarean delivery. Infants born after a trial of labor in breech presentation display low one-minute Apgar score and need intensive care more often compared to vertex controls

Full Text Available Background. In this study the effects of 24 weeks losartan and ramipril treatment, both alone and in combination, on blood pressure and left ventricular mass (LVM and function, have been evaluated in hypertensives. Methods. 57 hypertensives with stage 1 and 2 essential hypertension were included. After 4 weeks run in, a randomized double-blind, 3 arm, double dummy, independent trial was used. All patients were randomly allocated to 3 treatment arms consisting of losartan (50 mg/daily, ramipril (5 mg/daily, and combined (losartan 50 mg/ramipril 5 mg/daily for 24 weeks. LVM, LVM/h2.7 and other echocardiographic measurements, BUN, creatinine and clearance and potassium were determined after run in and 24 weeks. Results. All groups were comparable for gender, age, BMI, BP and LVM. The prevalence of baseline left ventricular hypertrophy (LVH was not significantly different among 3 groups. At the end of treatment, a significant (p<0.05 reduction in SBP, DBP, MBP, LVM and LVM/h2.7 were observed in all groups. The absolute and percent reduction in LVM/h2.7 were significantly higher in combined than losartan or ramipril groups and also in hypertensives with LVH. No significant change in absolute and percent reduction of SBP, DBP and MBP were found. Conclusions. These data indicate an additional cardioprotective effect of dual blockade of RAS in hypertensive patients with and without left ventricular hypertrophy.

During my first employment as a junior biologist conducting food habits analyses at the Patuxent Research Refuge (now Patuxent Wildlife Research Center) of the US Fish and Wildlife Service, the first station director, Arnold L. Nelson, gave each staff biologist the opportunity to spend a little time conducting field studies on the 2,600-acre research area. These studies were to help in ecological evaluation of the area, but also, no doubt, functioned as a morale builder for biologists daily engaged in difficult, demanding and confining laboratory work. I undertook to measure the population density of small mammals in different habitats. The state-of-the-art methods recommended to me and prevalent in the literature worried me, especially after preliminary field work. Reading the classic, paper by W.H. Burt [Terrioriality and home range concepts as applied to mammals. J. Mammalogy 24:346-352, 1943] was a turning point for me in seeing that knowledge of home-range size was the key to measuring population density. My first papers employed these concepts in field evaluations. However, they could give-only limited attention to the question of how home ranges could be measured. Furthermore, the importance of knowledge of the home range to habitat evaluation and to understanding animal behavior was becoming increasingly apparent. Advocacy of many different methods of measuring home ranges appeared in the literature. It did not seem possible to evaluate them objectively. It occurred to me that artificial populations could be used to help in understanding the mechanisms of measuring home ranges. The effects of random trap-visiting, bias toward central traps, trap-spacing, range shape, and other factors could be considered. So grids of traps were inked onto oversize graph paper, and simulated ranges were cut from plastic to be tossed as randomly as possible on the trap-grids. It was a slow, laborious job. Analysis showed that random captures in artificial populations produced

Preterm delivery (kinesthetic stimulation (TKS), a form of infant massage that incorporates kinesthetic movement, would increase bone strength and markers of bone accretion in preterm infants. Preterm, AGA infants (29-32 weeks) were randomly assigned to TKS (N=20) or Control (N=20). Twice daily TKS was provided 6 days per week for 2 weeks. Control infants received the same care without TKS treatment. Treatment was masked to parents, health care providers, and study personnel. Baseline and week two measures were collected for tibial speed of sound (tSOS, m/sec), a surrogate for bone strength, by quantitative ultrasound (Sunlight8000) and urine markers of bone metabolism, pyridinium crosslinks and osteocalcin (U-MidOC and unOC). Infant characteristics at birth and study entry as well as energy/nutrient intake were similar between TKS and Control. TKS intervention attenuated the decrease in tSOS observed in Control infants (p<0.05). Urinary pyridinium crosslinks decreased over time in both TKS and CTL (p<0.005). TKS infants experienced greater increases in urinary osteocalcin (U-MidOC, p<0.001 and unOC, p<0.05). We conclude that TKS improves bone strength in premature infants by attenuating the decrease that normally follows preterm birth. Further, biomarkers of bone metabolism suggest a modification in bone turnover in TKS infants in favor of bone accretion. Taken together, we speculate that TKS improves bone mineralization.

1. This study investigated the effect of incubation type and production system on geese growth traits. 2. A total of 216 geese were either naturally (114) or artificially (102) hatched and reared in intensive or free-range production systems (4 replicates each) until 18 weeks of age. 3. Weights of naturally hatched goslings (NHG) were significantly higher than artificially hatched goslings (AHG) at 2 weeks (644 vs. 536 g); however, weights of AHG were significantly higher than NHG at both 6 weeks (3245 vs. 3010 g) and 18 weeks (5212 vs. 4353 g). 4. AHG had better feed conversion ratios (FCRs) than NHG (6.21 vs. 6.46 at 18 weeks). Feed consumption of naturally hatched geese was found higher in first 4 weeks when compared to artificially hatched geese and artificially hatched geese consumed more feed than naturally hatched geese after 8 weeks. 5. Production system had insignificant effects on feed consumption, FCRs, viability and mutilation rates. 6. Slipped wings were more frequent in NHG than AHG (8.32% vs. 1.68% at 6 weeks; 23.84% vs. 5.12% between 7 and 18 weeks) and in free-range production when compared to intensive production (17.88% vs. 11.08% over the course of the production period). 7. The study results indicate that both artificially and NHG can be reared in free-range production systems without any loss in performance and in deference to animal welfare.

Knee joint distraction (KJD) is a surgical joint-preserving treatment in which the knee joint is temporarily distracted by an external frame. It is associated with joint tissue repair and clinical improvement. Initially, patients were submitted to an eight-week distraction period, and currently patients are submitted to a six-week distraction period. This study evaluates whether a shorter distraction period influences the outcome. Both groups consisted of 20 patients. Clinical outcome was assessed by WOMAC questionnaires and VAS-pain. Cartilaginous tissue repair was assessed by radiographic joint space width (JSW) and MRI-observed cartilage thickness. Baseline data between both groups were comparable. Both groups showed an increase in total WOMAC score; 24±4 in the six-week group and 32±5 in the eight-week group (both p<0.001). Mean JSW increased 0.9±0.3mm in the six-week group and 1.1±0.3mm in the eight-week group (p=0.729 between groups). The increase in mean cartilage thickness on MRI was 0.6±0.2mm in the eight-week group and 0.4±0.1mm in the six-week group (p=0.277). A shorter distraction period does not influence short-term clinical and structural outcomes statistically significantly, although effect sizes tend to be smaller in six week KJD as compared to eight week KJD.

Depression is common after acute coronary syndrome (ACS) and has adverse effects on prognosis. There are few evidence-based interventions for treating depression in ACS. This study investigated the efficacy and safety of escitalopram in treating depressive disorders identified 2-14 weeks after a confirmed ACS episode. A total of 217 patients with DSM-IV depressive disorders (121 major and 96 minor) and ACS were randomly assigned to receive escitalopram in flexible doses of 5-20 mg/d (n = 108) or placebo (n = 109) for 24 weeks. The study was conducted from 2007 to 2013. The primary outcome measure was the Hamilton Depression Rating Scale (HDRS). Secondary outcome measures included the Montgomery-Asberg Depression Rating Scale (MADRS), Beck Depression Inventory (BDI), Clinical Global Impressions-Severity of Illness scale (CGI-S), Social and Occupational Functioning Assessment Scale (SOFAS), and World Health Organization Disability Assessment Schedule-12. Cardiovascular safety outcomes included echocardiography, electrocardiography, laboratory test, body weight, and blood pressure results. Escitalopram was superior to placebo in reducing HDRS scores (mean difference = 2.3, P = .016, effect size = 0.38). Escitalopram was also superior to placebo in decreasing depressive symptoms evaluated by the MADRS, BDI, and CGI-S and in improving SOFAS functioning level. Escitalopram was not associated with any harmful changes in cardiovascular safety measures. Dizziness was significantly more frequently reported in the escitalopram group (P = .018), but there were no significant differences in any other adverse events. These results indicate that escitalopram has clinically meaningful antidepressant effects with no evidence of reduced cardiovascular safety in depressive disorder following ACS.

Free-ranging farm cats: home range size and predation on a livestock unit in Northwest Georgia.

Directory of Open Access Journals (Sweden)

Susanna E Kitts-Morgan

Full Text Available This study's objective was to determine seasonal and diurnal vs. nocturnal home range size, as well as predation for free-ranging farm cats at a livestock unit in Northwest Georgia. Seven adult cats were tracked with attached GPS units for up to two weeks for one spring and two summer seasons from May 2010 through August 2011. Three and five cats were tracked for up to two weeks during the fall and winter seasons, respectively. Feline scat was collected during this entire period. Cats were fed a commercial cat food daily. There was no seasonal effect (P > 0.05 on overall (95% KDE and 90% KDE or core home range size (50% KDE. Male cats tended (P = 0.08 to have larger diurnal and nocturnal core home ranges (1.09 ha compared to female cats (0.64 ha. Reproductively intact cats (n = 2 had larger (P < 0.0001 diurnal and nocturnal home ranges as compared to altered cats. Feline scat processing separated scat into prey parts, and of the 210 feline scats collected during the study, 75.24% contained hair. Of these 158 scat samples, 86 contained non-cat hair and 72 contained only cat hair. Other prey components included fragments of bone in 21.43% of scat and teeth in 12.86% of scat. Teeth were used to identify mammalian prey hunted by these cats, of which the Hispid cotton rat (Sigmodon hispidus was the primary rodent. Other targeted mammals were Peromyscus sp., Sylvilagus sp. and Microtus sp. Invertebrates and birds were less important as prey, but all mammalian prey identified in this study consisted of native animals. While the free-ranging farm cats in this study did not adjust their home range seasonally, sex and reproductive status did increase diurnal and nocturnal home range size. Ultimately, larger home ranges of free-ranging cats could negatively impact native wildlife.

Background. The pilot phase IIb VIKING study suggested that dolutegravir (DTG), a human immunodeficiency virus (HIV) integrase inhibitor (INI), would be efficacious in INI-resistant patients at the 50 mg twice daily (BID) dose. Methods. VIKING-3 is a single-arm, open-label phase III study in which therapy-experienced adults with INI-resistant virus received DTG 50 mg BID while continuing their failing regimen (without raltegravir or elvitegravir) through day 7, after which the regimen was optimized with ≥1 fully active drug and DTG continued. The primary efficacy endpoints were the mean change from baseline in plasma HIV-1 RNA at day 8 and the proportion of subjects with HIV-1 RNA <50 c/mL at week 24. Results. Mean change in HIV-1 RNA at day 8 was −1.43 log10 c/mL, and 69% of subjects achieved <50 c/mL at week 24. Multivariate analyses demonstrated a strong association between baseline DTG susceptibility and response. Response was most reduced in subjects with Q148 + ≥2 resistance-associated mutations. DTG 50 mg BID had a low (3%) discontinuation rate due to adverse events, similar to INI-naive subjects receiving DTG 50 mg once daily. Conclusions. DTG 50 mg BID–based therapy was effective in this highly treatment-experienced population with INI-resistant virus.

Investigation of acupuncture-point injection combined with intratumor injection of radionuclide phosphorus 32 in treatment of metastatic carcinoma

International Nuclear Information System (INIS)

Chou, H.C.

1986-01-01

Seventeen patients with carcinoma and three patients with benign lesions of the head were studied by acupuncture-point injection combined with intratumor injection of radionuclide P-32 for treatment of metastatic carcinoma. The metastatic cervical nodules shrank to half their original sizes within 2-3 weeks in five cases of nasopharyngeal carcinoma. The injected dose ranged from 0.222 to 0.421 mCi, approximately 10 times less than that given by the ordinary method. The acupuncture points are selected according to the Theory of Channels and Collaterals of Chinese traditional medicine. The mechanism of therapeutic action of radionuclide P-32 is possibly by the delivery of destructive ionizing radiation from beta emission properties of P-32. This method appears to offer a low-dose means of P-32 treatment of metastatic carcinoma

The effect of plumbagin (PB, 5-hydroxy-2-methyl-1,4-naphthoquinone) against newly excysted juveniles (NEJs) and 4-weeks-old immature parasites of Fasciola gigantica were compared with triclabendazole (TCZ). The anthelmintic efficacy of 1, 10 and 100μg/ml of PB or TCZ following incubation in vitro for 1-24h was compared using a combination of relative motility (RM), survival index (SI) and larval migration inhibition (LMI) assays for parasite viability. The RM and SI values of the PB-treated group decreased at a more rapid rate than the TCZ-treated group. For NEJs, the decreased RM values were first observed at 1h incubation with 1μg/ml PB, and 90% of flukes were killed at 24h. In contrast, in TCZ-treated groups a 10-fold higher concentration of TCZ (10μg/ml) resulted in only 9% dead parasites after 24h incubation. In 4-weeks-old juvenile parasites, PB reduced the RM value at 10μg/ml with 100% of flukes dead after 3h, while TCZ decreased RM values at the concentration of 100μg/ml but with only 5% of flukes killed at 24h. NEJs treated with PB exhibited 88%, 99% and 100% of LMIs at the concentrations of 1, 10 and 100μg/ml, respectively. NEJs incubated with TCZ have an LMI of only 32% at the highest concentration of 100μg/ml. Similarly PB had a significantly greater killing of immature 4weeks juvenile stages than TCZ at all concentrations; however, 4-weeks-old juvenile parasites were more resistant to killing by PB or TCZ at all concentrations when compared to NEJs. Further studies were carried out to investigate the alterations of the parasite tegument by scanning electron microscope (SEM). PB caused similar tegumental alterations in 4-weeks-old juveniles as those observed in TCZ treatment but with greater damage at comparative time points, comprising of swelling, blebbing and rupture of the tegument, loss of spines, and eventual erosion, lesion and desquamation of the total tegument. These data indicate that PB had a greater fasciolicidal effect against

Sugar cane straw and/or P-fertilizer phosphorus-32 labelled were added to a Red Yellow podzolic soil from Goiana-PE. The treated samples were used in a pot experiment, growing sorghum plants for 4 and 6 weeks, and in an incubation experiment with incubation periods of 1, 2, 3, 4 and 6 weeks without plants in order to follow the dynamics of the P added. After each harvest and incubation period the soil were analysed for 31 P and 32 P in the microbial biomass and in sequential extracts with resin (Pi), 0.5 M Na H Co 3 (Pi, Po) and 0.1 N NaOH (Pi, Po). The 31 P and 32 P contents of the sorghum in the pot experiment were also determined. (author)

Full Text Available Objectives. To demonstrate the feasibility of the prenatal diagnosis of partial androgen insensitivity syndrome by 3D-4D ultrasound. Methods. To report prenatal diagnosis of partial androgen insensitivity syndrome at 32nd week of gestation by 3D-4D ultrasound in a fetus with a 46XY karyotype, testing negative to the mutation analysis of SRY gene and the 5α-reductase 2 gene (SRD5A2. Results. 3D-4D surface rendering allows the detection of external and internal genital malformations and can address the prenatal diagnosis of PAIS and can exclude associated complications. Conclusions. Prenatal diagnosis of PAIS allows an adequate parental counseling and an early optimal management of the condition, not only for the psychological and social reflections but also for the avoidance of complications and postnatal morbidity due to misdiagnosis or delays in the treatment of the genital ambiguity.

Background VIKING-3 aimed to examine efficacy and safety of dolutegravir (DTG) 50 mg twice daily in patients with resistance to multiple ARV classes, including integrase inhibitors (INI). Methods RAL and/or EVG-resistant (current or historical) adult subjects with screening plasma HIV-1 RNA ≥500 c/mL and resistance to ≥2 other ART classes received open-label DTG 50 mg BID while continuing their failing regimen (without RAL/EVG). At Day 8 the background regimen was optimised and DTG continued. Activity of the optimized background regimen (OBR) was determined by Monogram Net Assessment. Primary endpoints were antiviral efficacy at Day 8 and Week 24. Results 183 subjects enrolled, 124 with INI-resistance at screening and 59 with historical (but no screening) resistance. Population was advanced: at BL, median CD4 140, prior ART 13 yrs, 56% CDC Class C; 79% had >2 NRTI, 75% >1 NNRTI, and 70% >2 PI resistance-associated mutations, and 61% had non-R5 HIV detected. Of the 114 subjects who had the opportunity to complete 24 weeks on study before data cutoff, 72 (63%) had 1 log HIV RNA decline of 2, respectively. Discontinuations due to adverse events were uncommon (6/183, 3%); the most common drug-related AEs were diarrhoea, nausea and headache, each reported in only 5% of subjects. Conclusion A majority of the highly treatment-experienced subjects in VIKING-3 achieved suppression with DTG-based therapy. Responses were associated with Baseline IN genotype but not OSS, highlighting the importance and independence of DTG antiviral activity. DTG had a low rate of discontinuation due to adverse events at 50 mg BID in this advanced patient population.

Prospective questionnaire administration study. To assess the ability to translate total and domain scores from Scoliosis Research Society (SRS)-24 to SRS-22r in a surgical-range, medical/interventional adolescent idiopathic scoliosis (AIS) patient population. Conversion of SRS-24 to SRS-22r is demonstrated in an operative cohort of patients with AIS, but not in a medical/interventional patient population. We simultaneously administered SRS-24 and SRS-22r questionnaires to 75 surgical-range, medical/interventional AIS patients and compared them. We performed analysis by regression modeling to produce conversion equations from SRS-24 to SRS-22r. The total SRS-24 score for these medical/interventional AIS patients was 92.5 ± 9.45 (mean, 3.9 ± 0.39), and the total SRS-22r score was 93.5 ± 9.63 (mean, 4.3 ± 0.44). The correlation between these 2 groups was fair (R 2 = 0.77) and improved to good when mental health or recall questions were removed. The correlation was also fair for total pain domains (R 2 = 0.73). However, there was poor correlation for general self-image (R 2 = 0.6) and unacceptable for post-treatment self-image (R 2 = 0.01), general function (R 2 = 0.52), activity function (R 2 = 0.56), and satisfaction (R 2 = 0.53). Compared with a published population of operative AIS patients, R 2 values for total SRS-24 scores, pain, general self-image, activity function, and satisfaction were similar (p > .05). The R 2 values for general function and combined general and activity function were significantly different between the operative and medical/interventional cohorts. Scoliosis Research Society-24 can be converted to SRS-22r scores with fair accuracy in the surgical-range, medical/interventional AIS patient population for total score, and total pain domains. The SRS-24 translates unacceptably to the SRS-22r in self-image, function, and satisfaction domains. The SRS-24 to SRS-22r conversion equations are similar to operative AIS patients, except for the

The pilot phase IIb VIKING study suggested that dolutegravir (DTG), a human immunodeficiency virus (HIV) integrase inhibitor (INI), would be efficacious in INI-resistant patients at the 50 mg twice daily (BID) dose. VIKING-3 is a single-arm, open-label phase III study in which therapy-experienced adults with INI-resistant virus received DTG 50 mg BID while continuing their failing regimen (without raltegravir or elvitegravir) through day 7, after which the regimen was optimized with ≥1 fully active drug and DTG continued. The primary efficacy endpoints were the mean change from baseline in plasma HIV-1 RNA at day 8 and the proportion of subjects with HIV-1 RNA <50 c/mL at week 24. Mean change in HIV-1 RNA at day 8 was -1.43 log10 c/mL, and 69% of subjects achieved <50 c/mL at week 24. Multivariate analyses demonstrated a strong association between baseline DTG susceptibility and response. Response was most reduced in subjects with Q148 + ≥2 resistance-associated mutations. DTG 50 mg BID had a low (3%) discontinuation rate due to adverse events, similar to INI-naive subjects receiving DTG 50 mg once daily. DTG 50 mg BID-based therapy was effective in this highly treatment-experienced population with INI-resistant virus. www.clinicaltrials.gov (NCT01328041) and http://www.gsk-clinicalstudywww.gsk-clinicalstudyregister.com (112574). © The Author 2014.

To identify the relative risks of mortality and morbidities for small for gestational age (SGA) infants in comparison with non-SGA infants born at 22 to 29 weeks' gestation. Data were collected (2006-2014) on 156 587 infants from 852 US centers participating in the Vermont Oxford Network. We defined SGA as sex-specific birth weight thin plate spline term on GA by SGA were used to calculate the adjusted relative risks and 95% confidence intervals for outcomes by GA. Compared with non-SGA infants, the risk of patent ductus arteriosus decreased for SGA infants in early GA and then increased in later GA. SGA infants were also at increased risks of mortality, respiratory distress syndrome, necrotizing enterocolitis, late-onset sepsis, severe retinopathy of prematurity, and chronic lung disease. These risks of adverse outcomes, however, were not homogeneous across the GA range. Early-onset sepsis was not different between the 2 groups for the majority of GAs, although severe intraventricular hemorrhage was decreased among SGA infants for only gestational week 24 through week 25. SGA was associated with additional risks to mortality and morbidities, but the risks differed across the GA range. Copyright © 2018 by the American Academy of Pediatrics.

The consumption of dietary antioxidants is considered to be a good strategy against photo-aging. However, the results of previous clinical trials that investigated the effects of oral consumption of high-flavanol cocoa products on skin photo-aging have been contradictory. The aim of this study was to investigate whether high-flavanol cocoa supplementation would improve the moderately photo-aged facial skin of female participants, by assessing skin wrinkles and elasticity. We performed a 24-wk, randomized, double-blind, placebo-controlled study to evaluate the effects of oral supplementation of cocoa flavanols on cutaneous photo-aging. All participants were moderately photo-aged Korean women with visible facial wrinkles (age range: 43-86 y). Participants were randomly assigned to receive a placebo beverage or cocoa beverage that contained 320 mg total cocoa flavanols/d. We measured wrinkles, skin elasticity, and hydration at baseline and at 12 and 24 wk. The primary endpoint was the mean percentage change in the average roughness value (Rz) at 24 wk. At 24 wk, the mean percentage change in Rz (primary endpoint) was significantly lower in the cocoa group than in the placebo group (-8.7 percentage points; 95% CI: -16.1, -1.3 percentage points; P = 0.023). The mean percentage changes in gross elasticity, as determined by a cutometer, also differed between the groups at 12 wk (9.1 percentage points; 95% CI: 1.5, 16.7 percentage points; P = 0.020) and 24 wk (8.6 percentage points; 95% CI: 1.0, 16.2 percentage points; P = 0.027). However, there were no significant differences in skin hydration and barrier integrity between the 2 groups. In moderately photo-aged women, regular cocoa flavanol consumption had positive effects on facial wrinkles and elasticity. Cocoa flavanol supplementation may contribute to the prevention of the progression of photo-aging.

We sought to evaluate whether serial amnioinfusions for persistent oligohydramnios can affect the perinatal and long-term outcomes in extreme cases of preterm premature rupture of membranes. All singleton pregnancies with preterm premature rupture of membranes at 4 days between January 1991 and June 1998 were included. Amniotic fluid volume was assessed as the maximum cord-free pocket with serial ultrasonographic examinations. Consenting women with persistent (>4 days) oligohydramnios (amniotic fluid amnioinfusions to maintain an amniotic fluid pocket >2 cm. The pregnancy, neonatal, and long-term neurologic outcomes of the cases that spontaneously maintained a median amniotic fluid pocket >2 cm (amnioinfusion-not-necessary group) were compared with those of women with oligohydramnios who underwent amnioinfusion but continued to have a median amniotic fluid pocket after preterm premature rupture of membranes amnioinfusion group). Statistical analysis included the Wilcoxon rank-sum test and the Fisher exact test, with a 2-tailed P amnioinfusions, which successfully restored a median amniotic fluid pocket >2 cm for >/=48 hours in 11 (30%) patients. This successful amnioinfusion group was comparable with the persistent oligohydramnios group (n = 25) in gestational age at first amnioinfusion (median, 20.2 weeks; range, 16-25.6 weeks; vs median, 20.3 weeks; range, 16.5-24.2 weeks; P =.4), number of amnioinfusions (median, 3; range, 1-9; vs median, 3; range, 1-5; P =.4), and interval between amnioinfusions (median, 6 days; range, 4-14 days; vs median, 8 days; range, 6-43 days; P =. 1). However, patients in the persistent oligohydramnios group had a significantly shorter interval to delivery, lower neonatal survival (20%), and higher rates of pulmonary hypoplasia (62%) and abnormal neurologic outcomes (60%) than the patients in the groups in which amnioinfusion was not necessary or was successful (all P amnioinfusions successfully alleviate oligohydramnios have a perinatal

Alkaptonuria (AKU) is a serious genetic disease characterised by premature spondyloarthropathy. Homogentisate-lowering therapy is being investigated for AKU. Nitisinone decreases homogentisic acid (HGA) in AKU but the dose-response relationship has not been previously studied. Suitability Of Nitisinone In Alkaptonuria 1 (SONIA 1) was an international, multicentre, randomised, open-label, no-treatment controlled, parallel-group, dose-response study. The primary objective was to investigate the effect of different doses of nitisinone once daily on 24-h urinary HGA excretion (u-HGA24) in patients with AKU after 4 weeks of treatment. Forty patients were randomised into five groups of eight patients each, with groups receiving no treatment or 1 mg, 2 mg, 4 mg and 8 mg of nitisinone. A clear dose-response relationship was observed between nitisinone and the urinary excretion of HGA. At 4 weeks, the adjusted geometric mean u-HGA24 was 31.53 mmol, 3.26 mmol, 1.44 mmol, 0.57 mmol and 0.15 mmol for the no treatment or 1 mg, 2 mg, 4 mg and 8 mg doses, respectively. For the most efficacious dose, 8 mg daily, this corresponds to a mean reduction of u-HGA24 of 98.8% compared with baseline. An increase in tyrosine levels was seen at all doses but the dose-response relationship was less clear than the effect on HGA. Despite tyrosinaemia, there were no safety concerns and no serious adverse events were reported over the 4 weeks of nitisinone therapy. In this study in patients with AKU, nitisinone therapy decreased urinary HGA excretion to low levels in a dose-dependent manner and was well tolerated within the studied dose range.

Full Text Available Background. Previous studies have demonstrated that once-weekly yoga classes are effective for chronic low back pain (cLBP in white adults with high socioeconomic status. The comparative effectiveness of twice-weekly classes and generalizability to racially diverse low income populations are unknown. Methods. We conducted a 12-week randomized, parallel-group, dosing trial for 95 adults recruited from an urban safety-net hospital and five community health centers comparing once-weekly (n=49 versus twice-weekly (n=46 standardized yoga classes supplemented by home practice. Primary outcomes were change from baseline to 12 weeks in pain (11-point scale and back-related function (23-point modified Roland-Morris Disability Questionnaire. Results. 82% of participants were nonwhite; 77% had annual household incomes <$40,000. The sample’s baseline mean pain intensity [6.9 (SD 1.6] and function [13.7 (SD 5.0] reflected moderate to severe back pain and impairment. Pain and back-related function improved within both groups (P<0.001. However, there were no differences between once-weekly and twice-weekly groups for pain reduction [-2.1 (95% CI -2.9, -1.3 versus −2.4 (95% CI -3.1, -1.8, P=0.62] or back-related function [-5.1 (95% CI -7.0, -3.2 versus −4.9 (95% CI -6.5, -3.3, P=0.83]. Conclusions. Twelve weeks of once-weekly or twice-weekly yoga classes were similarly effective for predominantly low income minority adults with moderate to severe chronic low back pain. This trial is registered with ClinicalTrials.gov NCT01761617.

The Wyoming Survey for Hα, or WySH, is a large-area, ground-based imaging survey for Hα-emitting galaxies at redshifts of z ∼ 0.16, 0.24, 0.32, and 0.40. The survey spans up to 4 deg 2 in a set of fields of low Galactic cirrus emission, using twin narrowband filters at each epoch for improved stellar continuum subtraction. Hα luminosity functions are presented for each Δz ∼ 0.02 epoch based on a total of nearly 1200 galaxies. These data clearly show an evolution with look-back time in the volume-averaged cosmic star formation rate. Integrals of Schechter fits to the incompleteness- and extinction-corrected Hα luminosity functions indicate star formation rates per comoving volume of 0.010, 0.013, 0.020, 0.022 h 70 M sun yr -1 Mpc -3 at z ∼ 0.16, 0.24, 0.32, and 0.40, respectively. Combined statistical and systematic measurement uncertainties are on the order of 25%, while the effects of cosmic variance are at the 20% level. The bulk of this evolution is driven by changes in the characteristic luminosity L * of the Hα luminosity functions, with L * for the earlier two epochs being a factor of 2 larger than L * at the latter two epochs; it is more difficult with this data set to decipher systematic evolutionary differences in the luminosity function amplitude and faint-end slope. Coupling these results with a comprehensive compilation of results from the literature on emission line surveys, the evolution in the cosmic star formation rate density over 0 ∼< z ∼< 1.5 is measured.

Radiophosphorus (32P) treatment of bone marrow disorders in dogs: 11 cases (1970-1987)

Smith, M.; Turrel, J.M.

Between March 1970 and February 1987, radiophosphorus ( 32 P) was used to treat bone marrow disorders in 6 dogs; 4 had polycythemia vera and 2 had essential thrombocythemia. Activities of 32 P given initially ranged from 2.4 to 3.3 mCi/m2. Four dogs responded well to 32 P treatment, with gradual resolution of high RBC or platelet counts. Two of these dogs died of intercurrent disease unrelated to their bone marrow disorder, before blood counts could be stabilized. Two dogs did not respond to the initial 32 P treatment nor to additional treatments with 32 P, and had clinical signs and blood counts stabilized by use of phlebotomy or chemotherapeutic agents. We reviewed and analyzed 5 other cases of bone marrow disorders in dogs treated with 32 P and included the findings from their records with the records of our 6 dogs in this retrospective analysis. Of the 8 dogs with polycythemia vera treated with 32 P, 5 were given a single treatment that controlled clinical signs and blood counts for the remainder of the follow-up period. Of the 3 dogs treated for thrombocytosis with 32 P, 2 had blood counts that responded to a single treatment

In recent studies, a relationship between both low body fat and low thicknesses of selected skinfolds has been demonstrated for running performance of distances from 100 m to the marathon but not in ultramarathon. We investigated the association of anthropometric and training characteristics with race performance in 63 male recreational ultrarunners in a 24-hour run using bi and multivariate analysis. The athletes achieved an average distance of 146.1 (43.1) km. In the bivariate analysis, body mass (r = -0.25), the sum of 9 skinfolds (r = -0.32), the sum of upper body skinfolds (r = -0.34), body fat percentage (r = -0.32), weekly kilometers ran (r = 0.31), longest training session before the 24-hour run (r = 0.56), and personal best marathon time (r = -0.58) were related to race performance. Stepwise multiple regression showed that both the longest training session before the 24-hour run (p = 0.0013) and the personal best marathon time (p = 0.0015) had the best correlation with race performance. Performance in these 24-hour runners may be predicted (r2 = 0.46) by the following equation: Performance in a 24-hour run, km) = 234.7 + 0.481 (longest training session before the 24-hour run, km) - 0.594 (personal best marathon time, minutes). For practical applications, training variables such as volume and intensity were associated with performance but not anthropometric variables. To achieve maximum kilometers in a 24-hour run, recreational ultrarunners should have a personal best marathon time of ∼3 hours 20 minutes and complete a long training run of ∼60 km before the race, whereas anthropometric characteristics such as low body fat or low skinfold thicknesses showed no association with performance.

Nearly all published studies of recurrent Clostridium difficile infections (CDI) report recurrent CDI within 8 weeks after the primary infection. This study explored the molecular characteristics of C. difficile isolates from the first recurrent CDI more than 8 weeks after the primary infection. Consecutive hospitalized patients with a recurrent CDI more than 8 weeks after a primary infection were enrolled prospectively from January 2008 to February 2011. All C. difficile isolates of the primary and recurrent infections were collected and subjected to polymerase chain reaction ribotyping and antimicrobial susceptibility testing. There were 62 cases of CDI in this study, which included 32 cases (51.6%) of recurrence due to the same ribotype of C. difficile, 26 (41.9%) cases due to a different ribotype, and four (6.5%) cases with 2-4 recurrences due to the same or different strains. One hundred and forty C. difficile isolates were obtained, which included 62 primary CDI isolates and 78 recurrent isolates. Ribotype 020 was the most common C. difficile strain in primary and recurrent infections. Ribotype 001 accounted for 15.4% (10/78) of recurrent infections and 3.2% (2/62) of primary infections (p = 0.0447). The minimum inhibitory concentration at 90% (MIC 90 ) values of linezolid, moxifloxacin, and clindamycin against type 001 strains were much higher, compared to the three other common ribotypes. Recurrent CDI more than 8 weeks after a primary infection can be caused by the same or different C. difficile ribotype at similar percentages. Ribotype 001 C. difficile strains, which have a lower susceptibility to antimicrobials, were isolated more frequently in patients with a recurrent CDI. Copyright © 2015. Published by Elsevier B.V.

Mineralization and volatilization of ring labelled 14 C-2,4-dichlorophenoxyacetic acid in soil was studied over a period of six weeks under laboratory conditions at 25 deg. C in three different soils collected from three sites, Delhi, Jaipur and Ludhiana. A very slow rate of both mineralization and volatilization was observed in all the three soils. The observed mineralization, was highest for the Delhi soil, 0.93%, followed by the Ludhiana soil, 0.73% and the Jaipur soil 0.14% in 42 days. The extent of volatilization was 0.46% for the Jaipur soil, 0.37% for the Ludhiana soil and 0.32% for the Delhi soil. (author)

Strength programs have been seen to be useful in minimizing the effects of sarcopenia, although intervention protocols may vary in their content and characteristics. The aim of this study was to demonstrate the influence of a particular strength protocol for the elderly. A total of 35 individuals took part in the study, with 18 in the exercise group (4 men and 14 women), and 17 in the control group (4 men and 13 women). The average age was 73. The exercise group carried out a strength training program at moderate to high intensity over 24 weeks. Strength was evaluated using the chair stand test, 2-minute step and 2 vertical jumps-squat jump (SJ), and countermovement jump (CMJ). Falls in both groups were also compared before and after the intervention, as well as their relationship with the chair stand variable. A tendency towards improvement was observed in all tests, with the exception of CMJ; while the control group showed a tendency in the opposite direction. Contrast between the two groups at the end of the intervention was notable in all the tests. An inverse relationship between the chair stand strength variable and the number of falls was evident. According to the results achieved, the training was perceived to exercise a positive influence on both the strength of the elderly people and a reduction of the number of falls. The gap between the two groups widened towards the end of the intervention. Copyright © 2013 SEGG. Published by Elsevier Espana. All rights reserved.

The traditional treatment for obesity which is based on a reduced caloric diet has only been partially successful. Contributing factors are not only a poor long-term dietary adherence but also a significant loss of lean body mass and subsequent reduction in energy expenditure. Both low-fat, high-carbohydrate diets and diets using low-glycaemic index (GI) foods are capable of inducing modest weight loss without specific caloric restriction. The purpose of this study was to investigate the feasibility and medium-term effect of a low-fat diet with high (low GI) carbohydrates on weight loss, body composition changes and dietary compliance. Obese patients were recruited from two obesity outpatient clinics. Subjects were given advise by a dietician, then they attended biweekly for 1-hour group meetings. Bodyweight and body composition were measured at baseline and after 24 weeks. One hundred and nine (91%) patients completed the study; after 24 weeks the average weight loss was 8.9 kg (98.6 vs. 89.7 kg; p fat mass (42.5 vs. 36.4 kg; p vs. 53.3 kg; p low-fat, low-GI diet led to a significant reduction of fat mass; adherence to the diet was very good. Our results suggest that such a diet is feasible and should be evaluated in randomized controlled trials.

We investigated the effect of a 24-week energy-restricted intervention with low or high dairy intake (LD or HD) on the metabolic profiles of urine, blood and feces in overweight/obese women by NMR spectroscopy combined with ANOVA-simultaneous component analysis (ASCA). A significant effect of dairy...... metabolism and gut microbial activity. In addition, a significant time effect on the blood metabolome was attributed to a decrease in blood lipid and lipoprotein levels due to the energy restriction. For the fecal metabolome, a trend for a diet effect was found and a series of metabolites, such as acetate...

The relative sensitivities of low-medium and high-Z elements from manganese to lead were investigated via their K α employing 75 μCi of 32 P. This was accomplished by preparing various synthetic mixtures of elements in the range 25 ≤Z≤82, then simply introducing 32 P solution to form source-samples. The advantages of excitation with 32 P, a pure β-emitter with a β max. energy at 1709 keV, include the following: excitation of all the K α x-rays from manganese to lead; the relative sensitivities of the K x-rays are all within one order of magnitude; the source itself does not produce any spectral lines; and the background can be greatly reduced by filtering. Excitation with 32 P is compared with that of a conventional 109 Cd source and some possible applications are discussed. (author)

The animals have been divided in two groups, according to the follow-up time (12 and 24 weeks and pursuant to the for form of laser application (continuous or two-point. A Holmium laser (pulsed, solid state, 2.1 micron waves, 40 watts, OmniTip 30º tip apparatus was used. After the animals were sacrificed, the proximal and distal length and width of the operated size of such rats were compared to those of the non-operated size be means of non-parametric testing (considering p=0,05. The length in the operated size was significantly bigger for both follow-up groups, when compared to the length of the non-operated size, however there was no significant difference in such measures in function of the type of laser application. In the same manner, the width, both in the proximal and distal regions, was significantly bigger in the operated size in both follow-up groups, without showing any significant difference whatsoever in function of the type of application. When the measures in both follow-up groups were compared, distal length and width showed a trend to become bigger after 24 weeks, while width in the proximal region was significantly bigger in this group. As for the subjective microscopic evaluation, both in longitudinal and cross sections, it was possible to observe and increase in the number of fibroblasts, mainly in the 12-week group. The average fibroblast concentration in the tendon with 24-week follow-up was group deemed to be intermediate between the 12-week group and non-operated tendon.

Full Text Available Abstract Background X-linked mental retardation (XLMR is the leading cause of mental retardation in males. Mutations in the ARX gene in Xp22.1 have been found in numerous families with both nonsyndromic and syndromic XLMR. The most frequent mutation in this gene is a 24 bp duplication in exon 2. Based on this fact, a panel of XLMR families linked to Xp22 was tested for this particular ARX mutation. Methods Genomic DNA from XLMR families linked to Xp22.1 was amplified for exon 2 in ARX using a Cy5 labeled primer pair. The resulting amplicons were sized using the ALFexpress automated sequencer. Results A panel of 11 families with X-linked mental retardation was screened for the ARX 24dup mutation. Four nonsyndromic XLMR families – MRX29, MRX32, MRX33 and MRX38 – were found to have this particular gene mutation. Conclusion We have identified 4 additional XLMR families with the ARX dup24 mutation from a panel of 11 XLMR families linked to Xp22.1. This finding makes the ARX dup24 mutation the most common mutation in nonsyndromic XLMR families linked to Xp22.1. As this mutation can be readily tested for using an automated sequencer, screening should be considered for any male with nonsyndromic MR of unknown etiology.

Recent studies have suggested that long-term oxytocin administration can alleviate the symptoms of autism spectrum disorder (ASD); however, factors influencing its efficacy are still unclear. We conducted a single-center phase 2, pilot, randomized, double-blind, placebo-controlled, parallel-group, clinical trial in young adults with high-functioning ASD, to determine whether oxytocin dosage and genetic background of the oxytocin receptor affects oxytocin efficacy. This trial consisted of double-blind (12 weeks), open-label (12 weeks) and follow-up phases (8 weeks). To examine dose dependency, 60 participants were randomly assigned to high-dose (32 IU per day) or low-dose intranasal oxytocin (16 IU per day), or placebo groups during the double-blind phase. Next, we measured single-nucleotide polymorphisms (SNPs) in the oxytocin receptor gene (OXTR). In the intention-to-treat population, no outcomes were improved after oxytocin administration. However, in male participants, Clinical Global Impression-Improvement (CGI-I) scores in the high-dose group, but not the low-dose group, were significantly higher than in the placebo group. Furthermore, we examined whether oxytocin efficacy, reflected in the CGI-I scores, is influenced by estimated daily dosage and OXTR polymorphisms in male participants. We found that >21 IU per day oxytocin was more effective than ⩽21 IU per day, and that a SNP in OXTR (rs6791619) predicted CGI-I scores for ⩽21 IU per day oxytocin treatment. No severe adverse events occurred. These results suggest that efficacy of long-term oxytocin administration in young men with high-functioning ASD depends on the oxytocin dosage and genetic background of the oxytocin receptor, which contributes to the effectiveness of oxytocin treatment of ASD.

Field-induced magnetic order in a structural disordered single-crystal Sr 14 Cu 24 O 41 (Sr 14 -B) has been observed in the Cu-nuclear magnetic resonance (NMR) measurements for the ladder sites below 20 K under the magnetic field H∼11 T. For the Zhang Rice (ZR) sites in the chains, the spectrum splits below 20 K due to an appearance of the internal field, whereas that of less disordered Sr 14 -A does not. This gives an evidence of three-dimensional (3D) long-range (LR) ordering in Sr 14 -B below T N ∼20 K under H∼11 T

Developmental exposure of mice to the environmental contaminant and AhR agonist, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), causes persistent postnatal suppression of T cell-mediated immune responses. The extent to which prenatal TCDD may induce or exacerbate postnatal autoimmune disease remains unknown. In the present study, time-pregnant high affinity AhR C57BL/6 mice received a single oral administration of 0, 2.5, or 5 μg/kg TCDD on gestation day (gd) 12. Offspring of these mice (n = 5/gender/treatment) were evaluated at 24 weeks-of-age and showed considerable immune dysregulation that was often gender-specific. Decreased thymic weight and percentages of CD4 + CD8 + thymocytes, and increased CD4 + CD8 - thymocytes, were present in the female but not male offspring. Males but not females showed decreased CD4 - CD8 + T cells, and increased Vβ3 + and Vβ17a + T cells, in the spleen. Males but not females also showed increased percentages of bone marrow CD24 - B220 + B cell progenitors. Antibody titers to dsDNA, ssDNA and cardiolipin displayed increasing trends in both male and female mice, reaching significance for anti-dsDNA in both genders and for ssDNA in males at 5 μg/kg TCDD. Immunofluorescent staining of IgG and C3 deposition in kidney glomeruli increased in both genders of prenatal TCDD-exposed mice, suggestive of early stages of autoimmune glomerulonephritis. Collectively, these results show that exposure to TCDD during immune system development causes persistent humoral immune dysregulation as well as altered cell-mediated responses, and induces an adult profile of changes suggestive of increased risk for autoimmune disease

A laboratory experiment was conducted to evaluate the dissolution of six sources of phosphate rock in two acid soils (Ultisols): a sandy soil and a red clay soil. Labile P was determined using the radioactive 32 P technique for Pi extractable P and resin extractable P. Incubations were conducted for 0, 1, 2, 3, 4 and 5 weeks for 32 P exchangeable technique, 0 and 5 weeks for Pi technique and 5 weeks for resin technique. Rates of PR were 0 and 400 mgP/ha. The results showed that labile P in the sandy soil decreased from 0-1 weeks for all the PRs except Hahotoe PR and Hazara PR's. Between 1 and 5 weeks labile P remained relatively constant. The ranking of labile P from PRs was: North Carolina = Kouribga > Matam > Hahotoe = Hazara> Patos de Minas. In the red soil, labile P from all PRs appeared to be relatively unchanged during the 0-5 week incubation. Pi extractable P in sandy soil showed no significant differences due to incubation time. In the red clay soil, there was a significant decrease in Pi-P extracted from soil mixtures with PRs after 5 weeks as compared to 0 weeks. Results of the Resin-extractable P in both sandy and red soils were in agreement with labile P as measured by 32 P exchange technique. (author)

To analyse the effect of a 24-week physical training programme in water and on land on women with fibromyalgia. A controlled study was conducted from December 2009 to May 2010. Seventy-two women with fibromyalgia (age: 51.79±7.87 years) were assigned to an exercise group (3 sessions/week, 2 sessions in water, 1 session on land) (n=42) and to a control group (n=30). The variables analysed were: number of tender points, visual analogue scale (VAS) of pain, algometer score, functional capacity (leg strength, hand-grip dynamometry, flexibility, agility, balance, aerobic endurance, heart response), body composition (body mass index, fat mass index, skeletal muscle mass index and percentage of body fat) and psychological variables (Fibromyalgia Impact Questionnaire [FIQ] and Short Form Health Survey 36 [SF-36]). The exercise group improved in the algometer score (pfibromyalgia.

Little is known about the ranging behaviour of chickens. Understanding ranging behaviour is required to improve management and shed and range design to ensure optimal ranging opportunities. Using Radio Frequency Identification technology, we tracked 300 individual broiler chickens in each of four mixed sex ROSS 308 flocks on one commercial farm across two seasons. Ranging behaviour was tracked from the first day of range access (21 days of age) until 35 days of age in winter and 44 days of age in summer. Range use was higher than previously reported from scan sampling studies. More chickens accessed the range in summer (81%) than winter (32%; p range use was greater in summer flocks (4.4 ± 0.1 visits for a total of 26.3 ± 0.8 min/day) than winter flocks (3.2 ± 0.2 visits for a total of 7.9 ± 1.0 min/day). Seasonal differences were only marginally explained by weather conditions and may reflect the reduction in range exposure between seasons (number of days, hours per day, and time of day). Specific times of the day ( p ranging and external factors that may explain ranging preferences.

Fetal intolerance of labor is a common indication for delivery by Caesarean section. Diagnosis is based on the presence of category III fetal heart rate tracing, which is an abnormal heart tracing associated with increased likelihood of fetal hypoxia and metabolic acidemia. This study analyzed data from 177 unique women who, during their prenatal visits (7-15 weeks and/or 24-32 weeks) to Atlanta area prenatal care clinics, consented to provide blood samples for DNA methylation (HumanMethylation450 BeadChip) and gene expression (Human HT-12 v4 Expression BeadChip) analyses. We focused on 57 women aged 18-36 (mean 25.4), who had DNA methylation data available from their second prenatal visit. DNA methylation patterns at CpG sites across the genome were interrogated for associations with fetal intolerance of labor. Four CpG sites (P value intolerance of labor. DNA methylation and gene expression were negatively associated when examined longitudinally during pregnancy using a linear mixed-effects model. Positive predictive values of methylation of these four sites ranged from 0.80 to 0.89, while negative predictive values ranged from 0.91 to 0.92. The four CpG sites were also associated with fetal intolerance of labor in an independent cohort (the Johns Hopkins Prospective PPD cohort). Therefore, fetal intolerance of labor could be accurately predicted from maternal blood samples obtained between 24-32 weeks gestation. Fetal intolerance of labor may be accurately predicted from maternal blood samples obtained between 24-32 weeks gestation by assessing DNA methylation patterns of SLC9B1. The identification of pregnant women at elevated risk for fetal intolerance of labor may allow for the development of targeted treatments or management plans.

Buprenorphine is an efficacious, widely used treatment for opioid use disorder (OUD). Daily oral transmucosal formulations can be associated with misuse, diversion, and nonadherence; these limitations may be obviated by a sustained release formulation. To evaluate the ability of a novel, weekly, subcutaneous buprenorphine depot formulation, CAM2038, to block euphorigenic opioid effects and suppress opioid withdrawal in non-treatment-seeking individuals with OUD. This multisite, double-blind, randomized within-patient study was conducted at 3 controlled inpatient research facilities. It involved 47 adults with DSM-V moderate-to-severe OUD. The study was conducted from October 12, 2015 (first patient enrolled), to April 21, 2016 (last patient visit). A total of five 3-day test sessions evaluated the response to hydromorphone (0, 6, and 18 mg intramuscular in random order; 1 dose/session/day). After the first 3-day session (ie, qualification phase), participants were randomized to either CAM2038 weekly at 24 mg (n = 22) or 32 mg (n = 25); the assigned CAM2038 dose was given twice, 1 week apart (day 0 and 7). Four sets of sessions were conducted after randomization (days 1-3, 4-6, 8-10, and 11-13). The primary end point was maximum rating on the visual analog scale for drug liking. Secondary end points included other visual analog scale (eg, high and desire to use), opioid withdrawal scales, and physiological and pharmacokinetic outcomes. A total of 46 of 47 randomized participants (mean [SD] age, 35.5 [9] years; 76% male [n = 35]) completed the study. Both weekly CAM2038 doses produced immediate and sustained blockade of hydromorphone effects (liking maximum effect, CAM2038, 24 mg: effect size, 0.813; P withdrawal (Clinical Opiate Withdrawal Scale, CAM2038, 24 mg: effect size, 0.617; P opioid blockade and withdrawal suppression. The results support the use of this depot formulation for treatment initiation and stabilization of patients with OUD, with

Marfan syndrome is a dominantly inherited connective tissue disorder with a wide range of phenotypic severity. The condition is the result of mutations in FBN1, a large gene composed of 65 exons encoding the fibrillin-1 protein. While mutations causing classic manifestations of Marfan syndrome have been identified throughout the FBN1 gene, the six previously characterized mutations resulting in the severe, perinatal lethal form of Marfan syndrome have clustered in exons 24-32 of the gene. We screened 8 patients with either neonatal Marfan syndrome or severe cardiovascular complications of Marfan syndrome for mutations in this region of the gene. Using intron-based exon-specific primers, we amplified exons 23-32 from genomic DNAs, screened these fragments by single-stranded conformational polymorphism analysis, and sequenced indicated exons. This analysis documented mutations in exons 25-27 of the FBN1 mutations in 6 of these patients. These results, taken together with previously published FBN1 mutations in this region, further define the phenotype associated with mutations in exons 24-32 of the FBN1 gene, information important for the development of possible diagnostic tests and genetic counseling. 49 refs., 4 figs., 2 tabs.

Purpose: To report long-term results of randomized trial comparing 2 accelerated fractionations of definitive radiation therapy assessing the need to irradiate during weekend in patients with head and neck squamous cell carcinoma. Methods and Materials: A total of 345 patients with SCC of the oral cavity, larynx, and oro- or hypo-pharynx, stage T2-4N0-1M0, were randomized to receive continuous accelerated irradiation (CAIR: once per day, 7 days per week) or concomitant accelerated boost (CB: once per day, 3 days per week, and twice per day, 2 days per week). Total dose ranged from 66.6-72 Gy, dose per fraction was 1.8 Gy, number of fractions ranged from 37-40 fractions, and overall treatment time ranged from 37-40 days. Results: No differences for all trial end-points were noted. At 5 and 10 years, the actuarial rates of local-regional control were 63% and 60% for CAIR vs 65% and 60% for CB, and the corresponding overall survival were 40% and 25% vs 44% and 25%, respectively. Confluent mucositis was the main acute toxicity, with an incidence of 89% in CAIR and 86% in CB patients. The 5-year rate of grade 3-4 late radiation morbidity was 6% for both regimens. Conclusions: Results of this trial indicate that the effects of accelerated fractionation can be achieve by delivering twice-per-day irradiation on weekday(s). This trial has also confirmed that an accelerated, 6-weeks schedule is a reasonable option for patients with intermediate-stage head-and-neck squamous cell carcinoma because of the associated high cure rate and minimal severe late toxicity.

BACKGROUND: Children born extremely premature (weight (weight. Much less is known about children of higher gestational ages and birth weights. We studied gestational age...... after 32 completed weeks and birth weight in relation to the child's school performance at the age of 10 years. METHODS: We performed a follow-up study of 5319 children born between January 1990 and June 1992. We got the information on birth weight and gestational age from birth registration forms; when...... the children were between 9 and 11 years of age, we gathered information about their school performance (reading, spelling, and arithmetic) from questionnaires completed by the parents and the children's primary school teachers. RESULTS: The association between birth weight and reading, as well as spelling...

In the last few decades, the energy crisis, increasing gas prices and concerns over environmental pollution have encouraged the development of electric vehicle (EV) and hybrid electric vehicle (HEV) technologies. In this paper, a thermal management system (TMS) installed in a range-extended electric vehicle is examined and is found to have a substantial impact on battery efficiency and vehicle performance. An exergy analysis was conducted on the refrigeration and coolant circuits and the Coefficient of Performance (COP) of the baseline system was determined to be 2.0 with a range of 1.8 to 2.4. The overall exergy was found to be 32% with a range of 26% to 39%. Ambient temperature had the largest impact on overall exergy efficiency but there is a need to further investigate temperature effects on battery efficiency, since the battery's performance has such a high impact on vehicle performance overall.

Purpose To evaluate the immediate and long-term safety as well as thrombus-capturing efficacy for 5 weeks after implantation of an absorbable inferior vena cava (IVC) filter in a swine model. Materials and Methods This study was approved by the institutional animal care and use committee. Eleven absorbable IVC filters made from polydioxanone suture were deployed via a catheter in the IVC of 11 swine. Filters remained in situ for 2 weeks (n = 2), 5 weeks (n = 2), 12 weeks (n = 2), 24 weeks (n = 2), and 32 weeks (n = 3). Autologous thrombus was administered from below the filter in seven swine from 0 to 35 days after filter placement. Fluoroscopy and computed tomography follow-up was performed after filter deployment from weeks 1-6 (weekly), weeks 7-20 (biweekly), and weeks 21-32 (monthly). The infrarenal IVC, lungs, heart, liver, kidneys, and spleen were harvested at necropsy. Continuous variables were evaluated with a Student t test. Results There was no evidence of IVC thrombosis, device migration, caval penetration, or pulmonary embolism. Gross pathologic analysis showed gradual device resorption until 32 weeks after deployment. Histologic assessment demonstrated neointimal hyperplasia around the IVC filter within 2 weeks after IVC filter deployment with residual microscopic fragments of polydioxanone suture within the caval wall at 32 weeks. Each iatrogenic-administered thrombus was successfully captured by the filter until resorbed (range, 1-4 weeks). Conclusion An absorbable IVC filter can be safely deployed in swine and resorbs gradually over the 32-week testing period. The device is effective for the prevention of pulmonary embolism for at least 5 weeks after placement in swine. © RSNA, 2017.

Human growth hormone (hGH) replacement therapy currently requires daily sc injections for years/lifetime, which may be both inconvenient and distressing for patients. NNC0195-0092 is a novel hGH derivative intended for once-weekly treatment of GH deficiency. A noncovalent albumin binding moiety is attached to the hGH backbone. Clearance is reduced as a consequence of a reversible binding to circulating serum albumin, which prolongs the pharmacodynamic (PD) effect. To evaluate safety, local tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of a single dose (SD) and multiple doses (MD) of NNC0195-0092. Randomized, single-center, placebo-controlled, double-blind, SD/MD, dose-escalation trial of 105 healthy male subjects. NNC0195-0092 sc administration: Five cohorts of eight subjects received one dose of NNC0195-0092 (0.01-0.32 mg/kg) (n = 6) or placebo (n = 2). Sixteen subjects (equal numbers of Japanese and non-Asian) received once-weekly doses of NNC0195-0092 (0.02-0.24 mg/kg; n=12) or placebo (n=4) for 4 weeks. Blood samples were drawn for assessment of safety, PK, IGF-1, and IGF binding protein 3 profiles and anti-drug antibodies. SD and MD of NNC0195-0092 were well tolerated at all dose levels. No safety concerns or local tolerability issues were identified. A dose-dependent IGF-1 response was observed. IGF-1 profiles suggest that NNC0195-0092 may be suitable for once-weekly dosing, with a clinically relevant dose ≤0.08 mg/kg/week. No differences in PK and PD were observed between Japanese and non-Asian subjects. SD and MD of NNC0195-0092 administered to healthy Japanese and non-Asian male subjects were well tolerated at all doses. The present trial suggests that NNC0195-0092 has the potential for an efficacious, well-tolerated, once-weekly GH treatment.

Brief explanation of the use of 32 Si in the dating of sediments. 32 Si , with a half-life of c.140 years, can be applied in the age range 30-1000 years. An appropriate dating tool for that time range is essential because it includes three very important epochs: the impact of human colonisation and industrialisation during the last 150 years, the Little Ice Age between about 1650 AD and 1850 AD, and the last part of the Medieval Climatic Optimum. 23 refs

Genome-wide association studies (GWAS) have identified common pancreatic cancer susceptibility variants at 13 chromosomal loci in individuals of European descent. To identify new susceptibility variants, we performed imputation based on 1000 Genomes (1000G) Project data and association analysis using 5,107 case and 8,845 control subjects from 27 cohort and case-control studies that participated in the PanScan I-III GWAS. This analysis, in combination with a two-staged replication in an additional 6,076 case and 7,555 control subjects from the PANcreatic Disease ReseArch (PANDoRA) and Pancreatic Cancer Case-Control (PanC4) Consortia uncovered 3 new pancreatic cancer risk signals marked by single nucleotide polymorphisms (SNPs) rs2816938 at chromosome 1q32.1 (per allele odds ratio (OR) = 1.20, P = 4.88×10−15), rs10094872 at 8q24.21 (OR = 1.15, P = 3.22×10−9) and rs35226131 at 5p15.33 (OR = 0.71, P = 1.70×10−8). These SNPs represent independent risk variants at previously identified pancreatic cancer risk loci on chr1q32.1 (NR5A2), chr8q24.21 (MYC) and chr5p15.33 (CLPTM1L-TERT) as per analyses conditioned on previously reported susceptibility variants. We assessed expression of candidate genes at the three risk loci in histologically normal (n = 10) and tumor (n = 8) derived pancreatic tissue samples and observed a marked reduction of NR5A2 expression (chr1q32.1) in the tumors (fold change -7.6, P = 5.7×10−8). This finding was validated in a second set of paired (n = 20) histologically normal and tumor derived pancreatic tissue samples (average fold change for three NR5A2 isoforms -31.3 to -95.7, P = 7.5×10−4-2.0×10−3). Our study has identified new susceptibility variants independently conferring pancreatic cancer risk that merit functional follow-up to identify target genes and explain the underlying biology.

Medium Range Forecasts Representation (and Long Range Forecasts?)

Vincendon, J.-C.

The progress of the numerical forecasts urges us to interest us in more and more distant ranges. We thus supply more and more forecasts with term of some days. Nevertheless, precautions of use are necessary to give the most reliable and the most relevant possible information. Available in a TV bulletin or on quite other support (Internet, mobile phone), the interpretation and the representation of a medium range forecast (5 - 15 days) must be different from those of a short range forecast. Indeed, the "foresee-ability” of a meteorological phenomenon decreases gradually in the course of the ranges, it decreases all the more quickly that the phenomenon is of small scale. So, at the end of some days, the probability character of a forecast becomes very widely dominating. That is why in Meteo-France the forecasts of D+4 to D+7 are accompanied with a confidence index since around ten years. It is a figure between 1 and 5: the more we approach 5, the more the confidence in the supplied forecast is good. In the practice, an indication is supplied for period D+4 / D+5, the other one for period D+6 / D+7, every day being able to benefit from a different forecast, that is be represented in a independent way. We thus supply a global tendency over 24 hours with less and less precise symbols as the range goes away. Concrete examples will be presented. From now on two years, we also publish forecasts to D+8 / J+9, accompanied with a sign of confidence (" good reliability " or " to confirm "). These two days are grouped together on a single map because for us, the described tendency to this term is relevant on a duration about 48 hours with a spatial scale slightly superior to the synoptic scale. So, we avoid producing more than two zones of types of weather over France and we content with giving an evolution for the temperatures (still, in increase or in decline). Newspapers began to publish this information, it should soon be the case of televisions. It is particularly

Previous studies have reported the detection of H5N1 HPAI virus in feathers from ducks naturally and experimentally infected and suggested that feather calami (FC) could be used as diagnostic samples for the early detection of H5N1 HPAI infections. Ducks are readily infected with H5N1 HPAI viruses although the development of clinical signs and deaths were reported as age-related with younger birds being more susceptible. The correlation between age and virus localisation in FC of infected ducks has not been studied to date. In the present study juvenile (4-week-old) and adult (24-week-old) Pekin ducks (Anas platyrhynchos var. domestica) were infected experimentally with a clade 2.2 H5N1 HPAI virus (A/duck/Nigeria/1071-23/2007). Tracheal (Tr) and cloacal (Cl) swabs and FC were collected at 3, 5, 7 and 10 days post infection and tested by RRT-PCR and a double antibody sandwich-ELISA (DAS-ELISA) developed in house. Virus was detected in swabs and FC of challenged ducks with a higher rate of detection in juvenile ducks. In this age group virus was detected over a longer period of time in FC compared to swabs. Our study showed that FC samples collected from young ducks are a valid diagnostic specimen for H5N1 HPAI virus detection. The DAS-ELISA on FC proved to be a suitable alternative diagnostic test when molecular and/or virus isolation techniques are not available therefore it could be useful in the diagnosis of H5N1 HPAI infections in under-resourced countries.

Full Text Available Due to the widespread use of silver nanoparticles in consumer products, the toxicity of silver nanoparticles has also been studied in relation to their application. However, most genotoxicity studies of silver nanoparticles have been performed in vitro. Therefore, this study evaluated the DNA damage to lung cells caused by repeated inhalation of silver nanoparticles. Male Sprague Dawley rats were exposed to silver nanoparticles for 12 weeks in a whole-body inhalation chamber. The animals were divided into one control group and three dose groups that were exposed to silver nanoparticles (14–15 nm diameter at concentrations of 0.66 × 106 particles/cm3 (49 μg/m3, low dose, 1.41 × 106 particles/cm3 (117 μg/m3, middle dose, and 3.24 × 106 particles /cm3 (381 μg/m3, high dose, respectively, for six hours/day over 12 weeks. The rats were sacrificed after the 12-week exposure period and the DNA damage assessed using a Comet assay of cells obtained from the right lungs. The olive tail moment values were 2.93 ± 0.19, 3.81 ± 0.23, 3.40 ± 0.22, and 5.16 ± 0.32 for the control, low-, middle-, and high-dose groups, respectively. Although no dose-dependent results were observed, a significant increase in the level of DNA damage was noted for the high-dose group.

COLLETTE Christian Institut Saint Laurent Liège Belgium. I am a science teacher at a technical high school. Generally, my students don't come from a privileged social background and are not particularly motivated for studies. For 10 years, I organize, for one of my sections, a spatial (and special) school year that ends in a spatial week. Throughout this year, with the help of my colleagues, I will introduce into all themes a lot of concepts relating to space. French, history, geography, English, mathematics, technical courses, sciences, and even gymnastics will be training actors in space culture. In spring, I will accompany my class in the Euro Space Center (Redu- Belgium) where we will live one week 24 hours on "like astronauts" One third of the time is dedicated to astronaut training (moonwalk, remote manipulator system, mission simulation, weightless wall, building rockets, satellites, etc.), One third to more intellectual activities on space (lectures, research, discovery of the outside run) the last one third of time in outside visits (museums, site of ESA-Redu) or in movies about space (October sky, Apollo 13, etc.) During this year, the profits, so educational as human, are considerable!

To investigate the safety, feasibility and efficacy of delayed cord clamping (DCC) compared with immediate cord clamping (ICC) at delivery among infants born at 22 to 27 weeks' gestation. This was a pilot, randomized, controlled trial in which women in labor with singleton pregnancies at 22 to 27 weeks' gestation were randomly assigned to ICC (cord clamped at 5 to 10 s) or DCC (30 to 45 s). Forty mother-infant pairs were randomized. Infants in the ICC and DCC groups had mean gestational ages (GA) of 24.6 and 24.4 weeks, respectively. No differences were observed between the groups across all available safety measures, although infants in the DCC group had higher admission temperatures than infants in the ICC group (97.4 vs. 96.2 °F, P=0.04). During the first 24 h of life, blood pressures were lower in the ICC group than in the DCC group (P<0.05), despite a threefold greater incidence of treatment for hypotension (45% vs. 12%, P<0.01). Infants in the ICC group had increased numbers of red blood transfusions (in first 28 days of life) than infants in DCC group (4.1±3.9 vs. 2.8±2.2, P=0.04). Among infants born at an average GA of 24 weeks', DCC appears safe, logistically feasible, and offers hematological and circulatory advantages compared with ICC. A more comprehensive appraisal of this practice is needed.

Treating tic disorder is challenging. No trial has ever examined whether twice weekly aripiprazole is effective for treating tic disorders. Participants of this 8-week randomized controlled parallel-group clinical trial were a clinical sample of 36 children and adolescents with tic disorder. Yale global tic severity scale was used to assess the outcome. Both groups received daily dosage of aripiprazole for the first 14 days. Then, one group received daily dose of aripiprazole while the other group received twice weekly dosage of aripiprazole for the next 46 days. The patients were assessed at baseline, week 2, 4, and 8. Tic scores decreased in both group significantly 22.8 (18.5) versus 22.0 (11.6). Moreover, there was no between group difference. The final mean (SD) score of motor and vocal tics in the group treated with daily treatment was not significantly different from the twice weekly group (Cohen's d = 0.36). The odds ratios for sedation and increased appetite were 3.05 and 3, respectively. For the first time, current findings support that twice weekly aripiprazole efficacy was not different from that of daily treatment. The rate of drowsiness in the twice weekly treatment group was less than that of the daily treatment group. This trial was registered at http://www.irct.ir. The registration number of this trial was: IRCT201312263930N32. http://www.irct.ir/searchresult.php?id=3930&number=32.

Full Text Available Background. Litramine (IQP-G-002AS was shown to be effective and safe for weight loss in overweight and obese subjects. However, long-term effectiveness on maintenance of body weight loss has yet to be ascertained. Objective. To assess effect of Litramine on maintenance of body weight loss. Methods. A double-blind, randomised, placebo-controlled trial on overweight and obese patients was conducted over two sites in Germany for 24 weeks. Subjects with documented previous weight loss of 3% over the last 3–6 months were randomised to groups given either Litramine (3 g/day or a matching placebo. Primary endpoints were difference of mean body weight (kg between baseline and end of study and maintenance of initially lost body weight in verum group, where maintenance is defined as ≤1% weight gain. Results. Subjects who were taking Litramine lost significantly more body weight compared to the subjects taking placebo who gained weight instead (-0.62±1.55 kg versus 1.62±1.48 kg, p<0.001. More importantly, 92% of subjects in Litramine group were able to maintain their body weight after initial weight loss, versus 25% in placebo group. No serious adverse events were reported throughout. Conclusion. Litramine is effective and safe for long-term body weight maintenance. Trial Registration. This trial is registered with Clinicaltrials.gov identifier: NCT01505387.

Accurate branching ratio values for twenty-two resonances in the reaction 23 Na(p,γ) 24 Mg and twenty-five resonances in the reaction 31 P(p,γ) 32 S have been measured with Ge(Li) spectrometers. The values were necessary for the accurate analysis of work of astrophysical interest, and also used for the assignment of possible Jsupπ values to nuclear levels. The two spectrometers used were calibrated for relative peak efficiency independently of previous Ge(Li) work; the calibrations were accurate to 6% and 10%. Extensive calculations were made of the finite solid angle effects of the detector on anisotropic gamma rays; the calculations were valid for geometries where the source did not lie on the detector axis. Work was carried out at the Australian Atomic Energy Commission; this was made possible by the assistance of the Australian Institute of Nuclear Science and Engineering. (author)

Bacterial sepsis is a major cause of morbidity and mortality in neonates, especially those involving methicillin-resistant Staphylococcus aureus (MRSA). Guidelines by the Infectious Diseases Society of America recommend the vancomycin 24-h area under the concentration-time curve to MIC ratio (AUC 24 /MIC) of >400 as the best predictor of successful treatment against MRSA infections when the MIC is ≤1 mg/liter. The relationship between steady-state vancomycin trough concentrations and AUC 24 values (mg·h/liter) has not been studied in an Asian neonatal population. We conducted a retrospective chart review in Singapore hospitals and collected patient characteristics and therapeutic drug monitoring data from neonates on vancomycin therapy over a 5-year period. A one-compartment population pharmacokinetic model was built from the collected data, internally validated, and then used to assess the relationship between steady-state trough concentrations and AUC 24 A Monte Carlo simulation sensitivity analysis was also conducted. A total of 76 neonates with 429 vancomycin concentrations were included for analysis. Median (interquartile range) was 30 weeks (28 to 36 weeks) for postmenstrual age (PMA) and 1,043 g (811 to 1,919 g) for weight at the initiation of treatment. Vancomycin clearance was predicted by weight, PMA, and serum creatinine. For MRSA isolates with a vancomycin MIC of ≤1, our major finding was that the minimum steady-state trough concentration range predictive of achieving an AUC 24 /MIC of >400 was 8 to 8.9 mg/liter. Steady-state troughs within 15 to 20 mg/liter are unlikely to be necessary to achieve an AUC 24 /MIC of >400, whereas troughs within 10 to 14.9 mg/liter may be more appropriate.

The availability of silicon photonic integrated circuits (ICs) in the 2-4 μm wavelength range enables miniature optical sensors for trace gas and bio-molecule detection. In this paper, we review our recent work on III-V-on-silicon waveguide circuits for spectroscopic sensing in this wavelength range. We first present results on the heterogeneous integration of 2.3 μm wavelength III-V laser sources and photodetectors on silicon photonic ICs for fully integrated optical sensors. Then a compact 2 μm wavelength widely tunable external cavity laser using a silicon photonic IC for the wavelength selective feedback is shown. High-performance silicon arrayed waveguide grating spectrometers are also presented. Further we show an on-chip photothermal transducer using a suspended silicon-on-insulator microring resonator used for mid-infrared photothermal spectroscopy.

Useful tools for determining absolute ages of sediments deposited within the last c. 100 years include 210 Pb, 137 Cs, and bomb radiocarbon. Cosmogenic 32 Si, with a half life of c. 140 years, can be applied in the age range 30-1000 years and is ideally suited for this time period. Detection of 32 Si is, however, very difficult due to its extremely low natural specific activity, and the vast excess of stable silicon (i.e. low 32 Si/Si ratio). 23 refs

Between May 2000 and May 2004, 31 women with FIGO stage IB2-IVA cervical cancer or with postsurgical pelvic recurrence were enrolled into this phase II study and randomized to receive on a weekly basis either 40 mg/m 2 Cisplatin (group I; 16 patients) or 50 mg/m 2 paclitaxel (group II; 15 patients) concurrently with radiotherapy. Median total dose to point A was 74 Gy (range: 66-92 Gy) for group I and 66 Gy (range: 40-98 Gy) for group II. Median follow-up time was 46 months. Patient and tumor characteristics were similar in both groups. The mean number of chemotherapy cycles was also comparable with 87% and 80% of patients receiving at least 4 doses in groups I and II, respectively. Seven patients (44%) of group I and 8 patients (53%) of group II developed tumor recurrence. The Median Survival time was not reached for Group I and 53 months for group II. The proportion of patients surviving at 2 and 5 years was 78% and 54% for group I and 73% and 43% for group II respectively. This small prospective study shows that weekly paclitaxel does not provide any clinical advantage over weekly cisplatin for concurrent chemoradiation for advanced carcinoma of the cervix

Free-range laying hen systems are increasing in number within Australia. Variation in outdoor stocking densities has led to development of a national information standard on free-range egg labeling, including setting a maximum density of 10,000 hens per hectare. However, there are few data on the impacts of differing outdoor densities on production and egg quality. ISA Brown hens in small (150 hens) flocks were housed in identical indoor pens, each with access (from 21 weeks) to different sized ranges simulating one of three outdoor stocking densities (2 replicates each: 2,000 hens/hectare (ha), 10,000 hens/ha, 20,000 hens/ha). Hen-day production was tracked from 21 through 35 weeks with eggs visually graded daily for external deformities. All eggs laid on one day were weighed each week. Eggs were collected from each pen at 25, 30, and 36 weeks and analyzed for egg quality. There were no effects of outdoor stocking density on average hen-day percentage production (P = 0.67), egg weight (P = 0.09), percentages of deformed eggs (P = 0.30), shell reflectivity (P = 0.74), shell breaking strength (P = 0.07), shell deformation (P = 0.83), or shell thickness (P = 0.24). Eggs from hens in the highest density had the highest percentage shell weight (P = 0.004) and eggs from the lowest density had the highest yolk color score (P egg quality is warranted. © 2017 Poultry Science Association Inc.

Our objective was to evaluate the feasibility, safety, and efficacy of intravenous (IV) infusion of allogenic mesenchymal stem cells (MSCs) in ankylosing spondylitis (AS) patients who are refractory to or cannot tolerate the side effects of nonsteroidal anti-inflammatory drugs (NSAIDs). AS patients enrolled in this study received four IV infusions of MSCs on days 0, 7, 14, and 21. The percentage of ASAS20 responders (the primary endpoint) at the fourth week and the mean ASAS20 response duration (the secondary endpoint) were used to assess treatment response to MSC infusion and duration of the therapeutic effects. Ankylosing Spondylitis Disease Activity Score Containing C-reactive Protein (ASDAS-CRP) and other preestablished evaluation indices were also adopted to evaluate the clinical effects. Magnetic resonance imaging (MRI) was performed to detect changes of bone marrow edema in the spine. The safety of this treatment was also evaluated. Thirty-one patients were included, and the percentage of ASAS20 responders reached 77.4% at the fourth week, and the mean ASAS20 response duration was 7.1 weeks. The mean ASDAS-CRP score decreased from 3.6 ± 0.6 to 2.4 ± 0.5 at the fourth week and then increased to 3.2 ± 0.8 at the 20th week. The average total inflammation extent (TIE) detected by MRI decreased from 533,482.5 at baseline to 480,692.3 at the fourth week (p > 0.05) and 400,547.2 at the 20th week (p < 0.05). No adverse effects were noted. IV infusion of MSCs is a feasible, safe, and promising treatment for patients with AS.

To determine the effect of infant feeding practices on postpartum weight change among HIV-infected and -uninfected women in South Africa. In a non-randomised intervention cohort study of antiretroviral therapy-naïve women in South Africa, infants were classified as exclusive (EBF), mixed (MF) or non-breastfed (NBF) at each visit. We analysed infant feeding cumulatively from birth to 5 months using 24-hour feeding history (collected weekly for each of the preceding 7 days). Using generalised estimating equation mixed models, allowing for repeated measures, we compared postpartum weight change (kg) from the first maternal postpartum weight within the first 6 weeks (baseline weight) to each subsequent visit through 24 months among 2340 HIV-infected and -uninfected women with live births and at least two postpartum weight measurements. HIV-infected (-0.2 kg CI: -1.7 to 1.3 kg; P = 0.81) and -uninfected women (-0.5 kg; 95% CI: -2.1 to 1.2 kg; P = 0.58) had marginal non-significant weight loss from baseline to 24 months postpartum. Adjusting for HIV status, socio-demographic, pregnancy-related and infant factors, 5-month feeding modality was not significantly associated with postpartum weight change: weight change by 24 months postpartum, compared to the change in the reference EBF group, was 0.03 kg in NBF (95% CI: -2.5 to +2.5 kg; P = 0.90) and 0.1 kg in MF (95% CI: -3.0 to +3.2 kg; P = 0.78). HIV-infected and -uninfected women experienced similar weight loss over 24 months. Weight change postpartum was not associated with 5-month breastfeeding modality among HIV-infected and -uninfected women. © 2014 John Wiley & Sons Ltd.

To evaluate the effect of antenatal treatment with a single dose of betamethasone between the 34th and the 36th week of pregnancy on the maturation of fetal lung. To study 100 pregnant women in their 34th-36th week of pregnancy who were diagnosed as susceptible to have preterm delivery. Fifty patients did not receive betamethasone (group 1). The other 50 patients were administered 12 mg betamethasone in a single dose (group 2). Patients who delivered at least 24 h after the administration of betamethasone were included in this study. After delivery, the Apgar score and the development of respiratory distress syndrome (RDS) in the neonates were compared. Group 2 babies had better Apgar scores when compared to group 1, and the difference was statistically significant. Sixteen (32%) neonates of group 1 and 7 (14%) neonates of group 2 required resuscitation, and the difference was statistically significant (p = 0.032; OR = 0.34, 95% CI 0.12-0.93). RDS was detected in 8 newborns of group 1 and 2 of group 2. The difference was statistically significant (p = 0.046; OR = 0.21, 95% CI 0.04-1.08). The administration of a single dose of betamethasone to pregnant women in their 34th-36th week of pregnancy who are likely to have preterm delivery reduces RDS development. There is a need for larger studies to confirm these results. Copyright 2010 S. Karger AG, Basel.

Online dietary assessment tools offer a convenient, low cost alternative to traditional dietary assessment methods such as weighed records and face-to-face interviewer-led 24-h recalls. INTAKE24 is an online multiple pass 24-h recall tool developed for use with 11-24 year-old. The aim of the study was to undertake a comparison of INTAKE24 (the test method) with interviewer-led multiple pass 24-h recalls (the comparison method) in 180 people aged 11-24 years. Each participant completed both an INTAKE24 24-h recall and an interviewer-led 24-h recall on the same day on four occasions over a one-month period. The daily energy and nutrient intakes reported in INTAKE24 were compared to those reported in the interviewer-led recall. Mean intakes reported using INTAKE24 were similar to the intakes reported in the interviewer-led recall for energy and macronutrients. INTAKE24 was found to underestimate energy intake by 1% on average compared to the interviewer-led recall with the limits of agreement ranging from minus 49% to plus 93%. Mean intakes of all macronutrients and micronutrients (except non-milk extrinsic sugars) were within 4% of the interviewer-led recall. Dietary assessment that utilises technology may offer a viable alternative and be more engaging than paper based methods, particularly for children and young adults.

Full Text Available Objective: To study the correlation of lipid metabolism characteristics with bile acid metabolism and placental hypoxia injury in patients with intrahepatic cholestasis of pregnancy (ICP. Methods: ICP pregnant women and healthy pregnant women who received antenatal care and delivered in Obstetrics Department of Panzhihua Maternal and Child Health Care Hospital between May 2013 and October 2016 were collected and included in ICP group and control group respectively. Serum lipid metabolism and bile acid metabolism indexes were measured at 20 weeks, 24 weeks, 28 weeks, 32 weeks and 36 weeks of gestation; mitochondria damage molecule expression levels in placenta were determined after childbirth. Results: Serum TC, LDL-C and HDL-C levels were not different between two groups of pregnant women at 20 weeks of gestation, and serum TC and LDL-C levels of ICP group at 24 weeks, 28 weeks, 32 weeks and 36 weeks of gestation were significantly higher than those of control group while HDL-C levels were significantly lower than those of control group; serum TBA, ALT and AST levels were not different between two groups of pregnant women at 20 weeks, 24 weeks and 28 weeks of gestation, and serum TBA, ALT and AST levels of ICP group at 32 weeks and 36 weeks of gestation were significantly higher than those of control group; CCO, ATPase, SDH and Bcl-2 protein expression in placenta tissue of ICP group were significantly lower than those of control group while Bax and Caspase-3 protein expression were significantly higher than those of control group. Serum LDL-C levels at 24 weeks, 28 weeks, 32 weeks and 36 weeks of gestation were positively correlated with TBA, ALT and AST levels in serum as well as Bax and Caspase-3 protein expression in placental tissue, and negatively correlated with CCO, ATPase, SDH and Bcl-2 protein expression in placental tissue. Conclusion: Midtrimester lipid metabolism characteristics can early predict the risk of ICP and evaluate the

Solar Spectral Irradiance Changes During Cycle 24

Science.gov (United States)

Marchenko, Sergey; Deland, Matthew

2014-01-01

We use solar spectra obtained by the Ozone Monitoring Instrument (OMI) on board the Aura satellite to detect and follow long-term (years) and short-term (weeks) changes in the solar spectral irradiance (SSI) in the 265-500 nm spectral range. During solar Cycle 24, in the relatively line-free regions the SSI changed by approximately 0.6% +/- 0.2% around 265 nm. These changes gradually diminish to 0.15% +/- 0.20% at 500 nm. All strong spectral lines and blends, with the notable exception of the upper Balmer lines, vary in unison with the solar "continuum." Besides the lines with strong chromospheric components, the most involved species include Fe I blends and all prominent CH, NH, and CN spectral bands. Following the general trend seen in the solar "continuum," the variability of spectral lines also decreases toward longer wavelengths. The long-term solar cycle SSI changes are closely, to within the quoted 0.1%-0.2% uncertainties, matched by the appropriately adjusted short-term SSI variations derived from the 27 day rotational modulation cycles. This further strengthens and broadens the prevailing notion about the general scalability of the UV SSI variability to the emissivity changes in the Mg II 280 nm doublet on timescales from weeks to years. We also detect subtle deviations from this general rule: the prominent spectral lines and blends at lambda approximately or greater than 350 nm show slightly more pronounced 27 day SSI changes when compared to the long-term (years) trends. We merge the solar data from Cycle 21 with the current Cycle 24 OMI and GOME-2 observations and provide normalized SSI variations for the 170-795 nm spectral region.

We investigated Gamow-Teller (GT) transitions and strength distributions of s-d shell N = Z nuclei, {sup 24}Mg, {sup 28}Si, and {sup 32}S, by a deformed quasi-particle random phase approximation (DQRPA). In the DQRPA, we included particle model space up to p-f shell and considered explicitly the deformation as well as the like- and unlike-pairing correlations. Shell evolution by deformation and attractive force by unlike-pairing correlations turned out to play vital roles to reproduce the experimental GT data. Correlations between the deformation and the pairing correlations are also discussed with the comparison to the experimental data shape. (orig.)

There is a pressing need for an effective dating tool to cover the historical past. Cosmogenic 32 Si, with a half-life of ca. 140 years, is ideally suited to provide time information in the range 50-1000 years. Detection of 32 Si is, however, very difficult due to extremely low natural concentrations and isotopic ratios. (author). 2 refs

2017-06-01

To investigate the influence of adding a weekly eccentric-overload training (EOT) session in several athletic performance's tests, 18 team-handball players were assigned either to an EOT (n = 11) or a Control (n = 7) group. Both groups continued to perform the same habitual strength training, but the EOT group added one session/week during a 7-week training programme consisting of four sets of eight repetitions for the bilateral half-squat and unilateral lunge exercises. The test battery included handball throwing velocity, maximum dynamic strength (1RM), countermovement jump (CMJ), 20 m sprint, triple hop for distance, and eccentric/concentric power in both the half-squat and lunge exercises. Data were analysed using magnitude-based inferences. Both groups improved their 1RM in the half squat, 20 m sprint time, and CMJ performance to a similar extent, but the EOT group showed a beneficial effect for both right [(42/58/0), possibly positive] and left [(99/1/0), very likely positive] triple hop for distance performance. In addition, the EOT group showed greater power output improvements in both eccentric and concentric phases of the half-squat (difference in percent of change ranging from 6.5% to 22.0%) and lunge exercises (difference in per cent of change ranging from 13.1% to 24.9%). Nevertheless, no group showed changes in handball throwing velocity. Selected variables related to team-handball performance (i.e. functional jumping performance, power output) can be improved by adding a single EOT session per week, highlighting the usefulness of this low-volume/high-intensity training when aiming at optimizing dynamic athletic performance.

Topical minoxidil formulations have been shown to be effective in treating androgenetic alopecia (AGA) for 12 months. Efficacy and safety in both frontotemporal and vertex regions over longer application periods have not been studied so far. To evaluate the effect of 5% minoxidil topical foam (5% MTF) in the frontotemporal and vertex areas in patients with moderate AGA over 104 weeks. An 80-week, open-label extension phase was performed, following a 24-week randomized, double-blind, placebo-controlled study in men with AGA grade IIIvertex to VI. Group 1 (n = 22) received ongoing 5% MTF for 104 weeks, Group 2 (n = 23) received placebo topical foam (plaTF) until week 24, followed by 5% MTF until week 104 during the extension phase. Frontotemporal and vertex target area non-vellus hair counts (f-TAHC, v-TAHC) and cumulative hair width (f-TAHW, v-TAHW) were assessed at baseline and at weeks 24, 52, 76 and 104. In Group 1, f-TAHW and f-TAHC showed a statistically significant increase from baseline to week 52 and week 76, respectively, returning to values comparable to baseline at week 104. No significant differences were found between baseline and week 104 in v-TAHC in Group 1 as well as f-TAHC, v-TAHC, f-TAHW and v-TAHW values in Group 2. 5% MTF is effective in stabilizing hair density, hair width and scalp coverage in both frontotemporal and vertex areas over an application period of 104 weeks, while showing a good safety and tolerability profile with a low rate of irritant contact dermatitis. © 2015 European Academy of Dermatology and Venereology.

Purpose: The aim of this study was to investigate prospectively the weekly volume changes in the target volumes and organs at risk and the resulting dosimetric changes during induction chemotherapy followed by chemoradiotherapy with intensity-modulated radiation therapy (C-IMRT) for head-and-neck cancer patients. Methods and Materials: Patients receiving C-IMRT for head-and-neck cancer had repeat CT scans at weeks 2, 3, 4, and 5 during radiotherapy. The volume changes of clinical target volume 1 (CTV1) and CTV2 and the resulting dosimetric changes to planning target volume 1 (PTV1) and PTV2 and the organs at risk were measured. Results: The most significant volume differences were seen at week 2 for CTV1 and CTV2. The reductions in the volumes of CTV1 and CTV2 at week 2 were 3.2% and 10%, respectively (p = 0.003 and p < 0.001). The volume changes resulted in a significant reduction in the minimum dose to PTV1 and PTV2 (2 Gy, p = 0.002, and 3.9 Gy, p = 0.03, respectively) and an increased dose range across PTV1 and PTV2 (2.5 Gy, p < 0.001, and 5.1 Gy, p = 0.008, respectively). There was a 15% reduction in the parotid volumes by week 2 (p < 0.001) and 31% by week 4 (p < 0.001). There was a statistically significant increase in the mean dose to the ipsilateral parotid only at week 4 (2.7 Gy, p = 0.006). The parotid glands shifted medially by an average of 2.3 mm (p < 0.001) by week 4. Conclusion: The most significant volumetric changes and dosimetric alterations in the tumor volumes and organs at risk during a course of C-IMRT occur by week 2 of radiotherapy. Further adaptive radiotherapy with replanning, if appropriate, is recommended.

The purpose of this study was to describe Canadian general surgery residents' perceptions regarding potential implementation of work-hour restrictions. An ethics review board-approved, Web-based survey was submitted to all Canadian general surgery residency programs between April and July 2009. Questions evaluated the perceived effects of an 80-hour work week on length of training, operative exposure, learning and lifestyle. We used the Fisher exact test to compare senior and junior residents' responses. Of 360 residents, 158 responded (70 seniors and 88 juniors). Among them, 79% reported working 75-100 hours per week. About 74% of seniors believed that limiting their work hours would decrease their operative exposure; 43% of juniors agreed (p seniors and juniors thought limiting their work hours would improve their lifestyle (86% v. 96%, p = 0.12). Overall, 60% of residents did not believe limiting work hours would extend the length of their training. Regarding 24-hour call, 60% of juniors thought it was hazardous to their health; 30% of seniors agreed (p = 0.001). Both senior and junior residents thought abolishing 24-hour call would decrease their operative exposure (84% v. 70%, p = 0.21). Overall, 31% of residents supported abolishing 24-hour call. About 47% of residents (41% seniors, 51%juniors, p = 0.26) agreed with the adoption of the 80-hour work week. There is a training-level based dichotomy of opinion among general surgery residents in Canada regarding the perceived effects of work hour restrictions. Both groups have voted against abolishing 24-hour call, and neither group strongly supports the implementation of the 80-hour work week.

To develop a menu and resource to illustrate to consumers and health professionals what a healthy balanced diet looks like over the course of a week. Development and analysis of an illustrative 7 d 'eatwell week' menu to meet current UK recommendations for nutrients with a Dietary Reference Value, with a daily energy base of 8368 kJ (2000 kcal). Foods were selected using market research data on meals and snacks commonly consumed by UK adults. Analysis used the food composition data set from year 1 (2008) of the UK National Diet and Nutrition Survey rolling programme. The eatwell week menu was developed using an iterative process of nutritional analysis with adjustments made to portion sizes and the inclusion/exclusion of foods in order to achieve the target macronutrient composition. Three main meals and two snacks were presented as interchangeable within the weekdays and two weekend days to achieve adult food and nutrient recommendations. Main meals were based on potatoes, rice or pasta with fish (two meals; one oily), red meat (two meals), poultry or vegetarian accompaniments. The 5-a-day target for fruit and vegetables (range 5-6·7 portions) was achieved daily. Mean salt content was below recommended maximum levels (<6 g/d). All key macro- and micronutrient values were achieved. Affordable foods, and those widely consumed by British adults, can be incorporated within a 7 d healthy balanced menu. Future research should investigate the effect of using the eatwell week on adults' dietary habits and health-related outcomes.

Very immature preterm infants are at risk of developing symptomatic or severe infection if cytomegalovirus is transmitted via breast milk. It is still a matter of debate whether human cytomegalovirus (HCMV) infection may lead to long-term sequelae. We hypothesized that symptomatic and severe HCMV infection transmitted via breast milk affects extremely immature infants at a very high rate. In 2012, untreated breast milk was fed to extremely low birth weight infants after parental informed consent was obtained. We retrospectively analyzed data on HCMV infection of infants born in 2012 between 22 and 24 weeks of gestation. 17 infants were born to HCMV IgG-seropositive mothers. 11 (65%) of these were diagnosed with symptomatic infection. In all cases, thrombocytopenia was the reason to analyze the infant's urine. HCMV infection was diagnosed at a median time of 12 weeks after birth. In 5 (45%) infants, thrombocytopenia was the only symptom and resolved without antiviral therapy or platelet transfusion. 6 (55%) infants developed sepsis-like disease with mildly elevated CRP values and showed signs of respiratory failure. 3 (27%) were able to be stabilized on CPAP, 3 (27%) had to be intubated and mechanically ventilated. 4 children were treated with ganciclovir and/or valganciclovir. 55% failed otoacoustic emissions and/or automated auditory brainstem response testing at discharge. In very immature infants born at the border of viability and suffering from multiple preexisting problems, HCMV infection may trigger a severe deterioration of the clinical course. © 2013 S.

This article describes a standardized test method for determining the effect of chemical substances on the reproduction of the earthworm Eisenia fetida andrei. It is based on the existing guidelines for acute toxicity testing with earthworms, and for reasons of standardization the same artificial soil substrate and earthworm species were chosen as prescribed by these guidelines. After being preconditioned for one week in untreated soil, earthworms are exposed to the chemical substances for 3 weeks. The number of cocoons produced is determined, and cocoons are incubated in untreated artificial soil for 5 weeks to assess hatchability. Results are presented from toxicity experiments with pentachlorophenol, copper, and 2,4-dichloroaniline. For these compounds no-effect levels (NEL) for cocoon production were 32, 60-120, and 56 mg.kg-1 dry soil, respectively. Hatching of cocoons was influenced by pentachlorophenol (NEL, 10 mg.kg-1), but not by copper and dichloroaniline. Following exposure, earthworms were incubated in clean soil again to study the possibility of recovery of cocoon production. For copper and dichloroaniline earthworms did recover cocoon production to a level as high as the control level or even higher; in case of pentachlorophenol, cocoon production was still reduced after 3 weeks in clean soil.

Metformin has been proffered as a therapy for adolescent obesity, although long-term controlled studies have not been reported. To test the hypothesis that 48 weeks of daily metformin hydrochloride extended release (XR) therapy will reduce body mass index (BMI) in obese adolescents, as compared with placebo. Multicenter, randomized, double-blind, placebo-controlled clinical trial. The 6 centers of the Glaser Pediatric Research Network from October 2003 to August 2007. Obese (BMI > or = 95th percentile) adolescents (aged 13-18 years) were randomly assigned to the intervention (n = 39) or placebo groups. Intervention Following a 1-month run-in period, subjects following a lifestyle intervention program were randomized 1:1 to 48 weeks' treatment with metformin hydrochloride XR, 2000 mg once daily, or an identical placebo. Subjects were monitored for an additional 48 weeks. Main Outcome Measure Change in BMI, adjusted for site, sex, race, ethnicity, and age and metformin vs placebo. After 48 weeks, mean (SE) adjusted BMI increased 0.2 (0.5) in the placebo group and decreased 0.9 (0.5) in the metformin XR group (P = .03). This difference persisted for 12 to 24 weeks after cessation of treatment. No significant effects of metformin on body composition, abdominal fat, or insulin indices were observed. Metformin XR caused a small but statistically significant decrease in BMI when added to a lifestyle intervention program. clinicaltrials.gov Identifiers: NCT00209482 and NCT00120146.

The potential energy governing the shape and the entrance and decay channels of the 12 C, 16 O, 20 Ne, 24 Mg, and 32 S 4n-nuclei has been determined within a generalized liquid drop model. Different three-dimensional and planar shapes have been investigated: linear chain, triangle, square, tetrahedron, pentagon, trigonal bipyramid, square pyramid, hexagon, octahedron, octogon and cube. The rms radii of the linear chains are higher than the experimental rms radii of the ground states. The binding energies of the planar shapes at the contact point are lower than the ones of the three-dimensional configurations. The a particle plus A-4 daughter configuration leads always to the lowest potential barrier relatively to the sphere configuration.

Somapacitan is a reversible albumin-binding growth hormone (GH) derivative, developed for once-weekly administration. This study aimed to evaluate the safety of once-weekly somapacitan vs once-daily Norditropin ® . Local tolerability and treatment satisfaction were also assessed. 26-week randomized, controlled phase 3 safety and tolerability trial in six countries (Nbib2382939). Male or female patients aged 18-79 years with adult GH deficiency (AGHD), treated with once-daily GH for ≥6 months, were randomized to once-weekly somapacitan ( n  = 61) or once-daily Norditropin ( n  = 31) administered subcutaneously by pen. Both treatments were dose titrated for 8 weeks to achieve insulin-like growth factor I (IGF-I) standard deviation score (SDS) levels within the normal range, and then administered at a fixed dose. Outcome measures were adverse events (AEs), including injection site reactions; occurrence of anti-somapacitan/anti-GH antibodies and change in treatment satisfaction, assessed using the Treatment Satisfaction Questionnaire for Medication-9 (TSQM-9). Mean IGF-I SDS remained between 0 and 2 SDS throughout the trial in both groups. AEs were mostly mild or moderate and transient in nature. The most common AEs were nasopharyngitis, headache and fatigue in both groups. More than 1500 somapacitan injections were administered and no clinically significant injection site reactions were reported. No anti-somapacitan or anti-GH antibodies were detected. The TSQM-9 score for convenience increased significantly more with somapacitan vs Norditropin ( P  = 0.0171). In this 26-week trial in patients with AGHD, somapacitan was well tolerated and no safety issues were identified. Once-weekly somapacitan was reported to be more convenient than once-daily Norditropin. © 2018 The authors.

To determine the association between antenatal steroids administration and intraventricular hemorrhage rates. We used cross-sectional data from the California Perinatal Quality Care Collaborative during 2007 to 2013 for infants ⩽32 weeks gestational age. Using multivariable logistic regression, we evaluated the effect of antenatal steroids on intraventricular hemorrhage, stratified by gestational age. In 25 979 very-low-birth weight infants, antenatal steroid use was associated with a reduction in incidence of any grade of intraventricular hemorrhage (odds ratio=0.68, 95% confidence interval: 0.62, 0.75) and a reduction in incidence of severe intraventricular hemorrhage (odds ratio=0.51, 95% confidence interval: 0.45, 0.58). This association was seen across gestational ages ranging from 22 to 29 weeks. Although current guidelines recommend coverage for preterm birth at 24 to 34 weeks gestation, our results suggest that treatment with antenatal steroids may be beneficial even before 24 weeks of gestational age.

Weekly serial 4DCT scans were acquired under free breathing conditions to assess water-equivalent path length (WEL) variations due to both intrafractional and interfractional changes in tissue thickness and density and to calculate proton dose distributions resulting from anatomical variations observed in serial 4DCT. A template of region of interests (ROIs) was defined on the anterior-posterior (AP) beam's eye view, and WEL measurements were made over these ROIs to quantify chest wall thickness variations. Interfractional proton dose distributions were calculated to assess changes in the expected dose distributions caused by range variations. Mean intrafractional chest wall WEL changes during respiration varied by: -4.1 mm (<-10.2 mm), -3.6 mm (<-7.1 mm), -3.2 mm (<-5.6 mm) and -2.5 mm (<-5.1 mm) during respiration in the ITV, upper, middle and lower lung regions, respectively. The mean interfractional chest wall WEL variation at Week 6 decreased by -4.0 mm (<-8.6 mm), -9.1 mm (<-17.9 mm), -9.4 mm (<-25.3 mm) and -4.5 mm (<-15.6 mm) in the ITV, upper, middle and lower lung regions, respectively. The variations were decomposed into anterior and posterior chest wall thickness changes. Dose overshoot beyond the target was observed when the initial boli was applied throughout the treatment course. This overshoot is due to chest wall thickness variations and target positional variations. The radiological path length can vary significantly during respiration as well as over the course of several weeks of charged particle therapy. Intrafractional/interfractional chest wall thickness changes can be a significant source of range variation in treatment of lung tumors with charged particle beams, resulting in dose distribution perturbations from the initial plan. Consideration of these range variations should be made in choosing the therapeutic charged particle beam range. (author)

Unitarity corrections to short-range order long-range rapidity correlations

CERN Document Server

Capella, A

1978-01-01

Although the effective hadronic forces have short range in rapidity space, one nevertheless expects long-range dynamical correlations induced by unitarity constraints. This paper contains a thorough discussion of long-range rapidity correlations in high-multiplicity events. In particular, the authors analyze in detail the forward- backward multiplicity correlations, measured recently in the whole CERN ISR energy range. They find from these data that the normalized variance of the number n of exchanged cut Pomerons, ((n/(n)-1)/sup 2/) , is most probably in the range 0.32 to 0.36. They show that such a number is obtained from Reggeon theory in the eikonal approximation. The authors also predict a very specific violation of local compensation of charge in multiparticle events: The violation should appear in the fourth-order zone correlation function and is absent in the second-order correlation function, the only one measured until now.

2016-01-01

The aim of this study was to investigate the relationship between survival and incidence of bronchopulmonary dysplasia (BPD) in extremely premature infants, and identify clinical factors responsible for this association. Medical records of 350 infants at 23–26 weeks gestation from 2000 to 2005 (period I, n = 137) and 2006 to 2010 (period II, n = 213) were retrospectively reviewed. The infants were stratified into 23–24 and 25–26 weeks gestation, and the survival, BPD incidence, and clinical characteristics were analyzed. BPD was defined as oxygen dependency at 36 weeks postmenstrual age. The overall survival rate was significantly improved in period II compared to period I (80.3% vs. 70.0%, respectively; P = 0.028), especially in infants at 23–24 weeks gestation (73.9% vs. 47.4%, respectively; P = 0.001). The BPD incidence in survivors during period II (55.0%) was significantly decreased compared to period I (67.7%; P = 0.042), especially at 25–26 weeks gestation (41.7% vs. 62.3%, respectively; P = 0.008). Significantly improved survival at 23–24 weeks gestation was associated with a higher antenatal steroid use and an improved 5-minute Apgar score. A significant decrease in BPD incidence at 25–26 weeks gestation was associated with early extubation, prolonged use of less invasive continuous positive airway pressure, and reduced supplemental oxygen. Improved perinatal and neonatal care can simultaneously lead to improved survival and decreased BPD incidence in extremely premature infants. PMID:26955244

Highlights: ► We study the VUV photoionization of acetamide in the 8–24 eV photon energy range. ► Electron/ion coincidence measurements are performed using synchrotron radiation. ► The adiabatic ionization energy of acetamide is determined by TPEPICO measurements. ► VUV induced fragmentation pathways of acetamide are assigned and discussed. - Abstract: A VUV photoionization study of acetamide was carried out over the 8–24 eV photon energy range using synchrotron radiation and photoelectron/photoion coincidence (PEPICO) spectroscopy. Threshold photoelectron photoion coincidence (TPEPICO) measurements were also made. Photoion yield curves and branching ratios were measured for the parent ion and six fragment ions. The adiabatic ionization energy of acetamide was determined as I.E. (1 2 A′) = (9.71 ± 0.02) eV, in agreement with an earlier reported photoionization mass spectrometry (PIMS) value. The adiabatic energy of the first excited state of the ion, 1 2 A″, was determined to be ≈10.1 eV. Assignments of the fragment ions and the pathways of their formation by dissociative photoionization were made. The neutral species lost in the principal dissociative photoionization processes are CH 3 , NH 2 , NH 3 , CO, HCCO and NH 2 CO. Heats of formation are derived for all ions detected and are compared with literature values. Some astrophysical implications of these results are discussed.

Many people find that their sleep is restricted or disturbed by social obligations, including work. Sleep phase delays can affect an individual's circadian rhythms on the following day and cause daytime sleepiness and/or poor performance. In this study, to examine weekly variations in sleep patterns, we analyzed sleep data for seven-day periods (from Sunday to Saturday) that had been collected from 2914 subjects (aged 20-79 years) over a total of 24,899 subject-weeks using contactless biomotion sensors. On the weekend, the subjects' mean sleep midpoint, bedtime, and wake-up time were delayed by 40, 26 and 53 min, respectively, compared with those seen on weekdays. In addition, on weekdays, the mean difference between the maximum and median sleep midpoint ranged from 35 to 47 min among the subjects in their 20 s-70 s. The weekend delay and weekday variation in the subjects' sleep patterns tended to decrease with age. This study detected sleep pattern disturbances on both weekdays and weekends. The serial changes in weekday bedtimes detected in this study suggest that sleep habits are influenced by changes in the temporal patterns of social activities/duties. We need further study the advantages of getting extra sleep and the disadvantages of sleep pattern disturbances in daily lifestyle.

the main way to increase these indices. Conversely, resistance training (RT is not typically prescribed for this purpose. In elderly subjects, it has been suggested that RT may increase aerobic capacity; however, the literature is controversial. The purpose of the present study was to verify the effects of 24 weeks of RT on aerobic capacity indexes of elderly women. METHOD: Fifty elderly women voluntarily took part in this study and were divided into two possible groups: control group (CG - n=25; mean age of 68.00 ± 6.38 years and training group (TG - n=25; mean age of 68.04 ± 6.78 years. All volunteers underwent cardiopulmonary exercise test on treadmill until volitional exhaustion before and after the intervention period. A split plot ANOVA test was used to examine differences within and between groups. RESULTS: It was observed that the TG exhibited significant increase in the variables time of test and oxygen uptake for both AT and exhaustion moments. The CG did not show any significant alterations for any of the dependent variables. CONCLUSIONS: It can be concluded that 24 weeks of RT are capable of promoting improvement in performance during a cardiopulmonary exercise test in a sample of elderly women. Further studies are necessary to elucidate the mechanisms responsible for these adaptations.

To study whether pregnancy week at delivery is an independent risk factor for shoulder dystocia. Population study. Medical Birth Registry of Norway. All vaginal deliveries of singleton offspring in cephalic presentation in Norway during 1967 through 2009 (n = 2,014,956). The incidence of shoulder dystocia was calculated according to pregnancy week at delivery. The associations of pregnancy week at delivery with shoulder dystocia were estimated as crude and adjusted odds ratios using logistic regression analyses. We repeated the analyses in pregnancies with and without maternal diabetes. Shoulder dystocia at delivery. The overall incidence of shoulder dystocia was 0.73% (n = 14,820), and the incidence increased by increasing pregnancy week at delivery. Birthweight was strongly associated with shoulder dystocia. After adjustment for birthweight, induction of labour, use of epidural analgesia at delivery, prolonged labour, forceps-assisted and vacuum-assisted delivery, parity, period of delivery and maternal age in multivariable analyses, the adjusted odds ratios for shoulder dystocia were 1.77 (1.42-2.20) for deliveries at 32-35 weeks of gestation, and 0.84 (0.79-0.88) at 42-43 weeks of gestation, using weeks 40-41 as the reference. In pregnancies affected by diabetes (n = 11,188), the incidence of shoulder dystocia was 3.95%, and after adjustment for birthweight the adjusted odds ratio for shoulder dystocia was 2.92 (95% CI 1.54-5.52) for deliveries at weeks 32-35 of gestation, and 0.91 (95% CI 0.50-1.66) at 42-43 weeks of gestation. The risk of shoulder dystocia was associated with increased birthweight, diabetes, induction of labour, use of epidural analgesia at delivery, prolonged labour, forceps-assisted and vacuum-assisted delivery, parity and period of delivery but not with post-term delivery. © 2013 Royal College of Obstetricians and Gynaecologists.

Clinically significant cognitive impairment, particularly in attention/executive and memory function, is found in many patients undergoing bariatric surgery. These difficulties have previously been linked to decreased weight loss 12 months after surgery, but more protracted examination of this relationship has not yet been conducted. The present study prospectively examined the independent contribution of cognitive function to weight loss 24 months after bariatric surgery. Given the rapid rate of cognitive improvement observed after surgery, postoperative cognitive function (i.e., cognition 12 weeks after surgery, controlling for baseline cognition) was expected to predict lower body mass index (BMI) and higher percent total weight loss (%WL) at 24-month follow-up. Data were collected by 3 sites of the Longitudinal Assessment of Bariatric Surgery (LABS) parent project. Fifty-seven individuals enrolled in the LABS project who were undergoing bariatric surgery completed cognitive evaluation at baseline, 12 weeks, and 24 months. BMI and %WL were calculated for 24-month postoperative follow-up. Better cognitive function 12 weeks after surgery predicted higher %WL and lower BMI at 24 months, and specific domains of attention/executive and memory function were robustly related to decreased BMI and greater %WL at 24 months. Results show that cognitive performance shortly after bariatric surgery predicts greater long-term %WL and lower BMI 24 months after bariatric surgery. Further work is needed to clarify the degree to which this relationship is mediated by adherence to postoperative guidelines. Copyright © 2013 American Society for Bariatric Surgery.

Treatment of rheumatoid arthritis (RA) with a combination of methotrexate (MTX)+adalimumab (ADA) is more effective than ADA monotherapy. We assessed the toxicity of different doses of MTX and treatment efficacy of ADA+MTX in two trials. Data originated from CONCERTO, in patients with early RA initiating ADA+ 2.5, 5, 10 or 20 mg/week MTX for 26 weeks; and MUSICA, in patients with an inadequate response to MTX initiating ADA+ 7.5 or 20 mg/week MTX for 24 weeks. Efficacy was assessed by the American College of Rheumatology 50 (ACR50). Patient-reported MTX-related toxicity information was collected at each visit on 18 prespecified MTX-related adverse events (AE) in the MTX label. In CONCERTO, ACR50 rates increased over time, ranging from 54% to 68% at week 26, while AE rates remained steady, ranging from 2.4% to 17.8% at week 26. Of 395 patients, 113 (28.6%) reported 345 MTX-related AEs, including one serious AE (SAE, excessive fatigue and/or malaise); 10 AEs (in two patients) led to study discontinuation. In MUSICA, ACR50 rates increased over time, and were 32.3% and 37.5% at week 24, while MTX-related AE rates remained steady and were 6.5% at week 24. Of 309 patients, 71 (23%) reported 185 MTX-related AEs, including 5 SAEs (four infections and one fever/chills); six AEs (in four patients) led to study discontinuation. In patients with RA initiating ADA+MTX combination, treatment efficacy was achieved and increased throughout both trials, while rates of MTX-related AEs remained steady. MTX-related AEs were observed in up to 30% of patients and most were mild. MTX was discontinued by 0.5%-1.3% of patients. MUSICA (NCT01185288), CONCERTO (NCT01185301), Post results.

Little is known about the effect of accessing an outdoor range on chicken welfare. We tracked individual ranging behavior of 538 mixed-sex Ross 308 chickens on a commercial farm across 4 flocks in winter and summer. Before range access, at 17 to 19 d of age, and post-range access, at 30 to 33 and 42 to 46 d of age in winter and summer flocks respectively, welfare indicators were measured on chickens (pre-range: winter N = 292; summer N = 280; post-range: winter N = 131; summer N = 140), including weight, gait score, dermatitis and plumage condition. Post-ranging autopsies were performed (winter: N = 170; summer: N = 60) to assess breast burn, leg health, and ascites. Fewer chickens accessed the range in winter flocks (32.5%) than summer flocks (82.1%). Few relationships between welfare and ranging were identified in winter, likely due to minimal ranging and the earlier age of post-ranging data collection compared to summer flocks. In summer flocks prior to range access, chickens that accessed the range weighed 4.9% less (P = 0.03) than chickens that did not access the range. Pre-ranging weight, gait score, and overall plumage cover predicted the amount of range use by ranging chickens in summer flocks (P ranging behavior. In summer flocks post-range access, ranging chickens weighed 12.8% less than non-ranging chickens (P range visits were associated with lower weight (P range was associated with lower weight (P range in summer is partly related to changes in broiler chicken welfare. Further investigations are required to determine causation.

Objectives To evaluate the effect of certolizumab pegol (CZP) on productivity outside and within the home, and on participation in family, social and leisure activities in adult patients with psoriatic arthritis (PsA). Methods RAPID-PsA (NCT01087788) is a phase 3, double-blind, placebo-controlled trial. 409 patients with active PsA were randomised 1:1:1 to placebo, CZP 200 mg every 2 weeks (Q2W) or CZP 400 mg every 4 weeks (Q4W). The arthritis-specific Work Productivity Survey (WPS) assessed the impact of PsA on paid work and household productivity, and participation in social activities during the preceding month. WPS responses were compared between treatment arms using a non-parametric bootstrap-t method. Results At baseline, 56.6%, 60.1% and 61.5% of placebo, CZP 200 mg Q2W and CZP 400 mg Q4W patients were employed. By week 24, employed CZP patients reported an average of 1.0–1.8 and 3.0–3.9 fewer days of absenteeism and presenteeism, respectively, per month compared with 1.0 and 0.3 fewer days for placebo patients (pproductivity or days lost for participation in family, social and leisure activities. Improvements with CZP were seen as early as week 4 and continued to week 24. Conclusions CZP treatment significantly improved productivity at paid work and within the home, and resulted in greater participation in social activities for PsA patients.

The investigation of translocation 2,4-D herbicides using 14 C as tracer on irradiated rice plant system. Condition of the soil was two kinds, that is normal soil and soil 30% up normal. The soil of rice field was spray with 1μCi of 2,4-D non labelled, one week after planting. A part of rice plant and weed was determined the radioactivity after 0, 2, 4, 8, and 10 weeks after spraying. The result showed that radioactivity maximum after zero week was in root and leaf of weeds, the second weeks in root of rice, the forth weeks in rice stick, and eighth weeks in leaf of rice. This result occur at normal condition soil of solid 30 % up normal soil. The residues of 2.4-D in rice was 4,24x10 -3 ppb at normal soil and 3.16x10 -3 ppb at solid 30% up normal soil. This result still lower than rate of WHO/FAO, that is 0,05 ppm

Dolutegravir (DTG; S/GSK1349572), a human immunodeficiency virus type 1 (HIV-1) integrase inhibitor, has limited cross-resistance to raltegravir (RAL) and elvitegravir in vitro. This phase IIb study assessed the activity of DTG in HIV-1-infected subjects with genotypic evidence of RAL resistance. Subjects received DTG 50 mg once daily (cohort I) or 50 mg twice daily (cohort II) while continuing a failing regimen (without RAL) through day 10, after which the background regimen was optimized, when feasible, for cohort I, and at least 1 fully active drug was mandated for cohort II. The primary efficacy end point was the proportion of subjects on day 11 in whom the plasma HIV-1 RNA load decreased by ≥0.7 log(10) copies/mL from baseline or was <400 copies/mL. A rapid antiviral response was observed. More subjects achieved the primary end point in cohort II (23 of 24 [96%]), compared with cohort I (21 of 27 [78%]) at day 11. At week 24, 41% and 75% of subjects had an HIV-1 RNA load of <50 copies/mL in cohorts I and II, respectively. Further integrase genotypic evolution was uncommon. Dolutegravir had a good, similar safety profile with each dosing regimen. Dolutegravir 50 mg twice daily with an optimized background provided greater and more durable benefit than the once-daily regimen. These data are the first clinical demonstration of the activity of any integrase inhibitor in subjects with HIV-1 resistant to RAL.

Executive Summary: An existing Ka-band (32 GHz, 9mm) catalog of 450+ sources is being monitored every 6-10 weeks on Giga-lambda baselines. These observations are sensitive to parsec scale activity in the AGN cores providing unique tests of gamma ray emission models. Abstract: The Fermi Large Area Telescope (LAT) has now released the 2nd catalog of high-energy gamma-ray sources (2FGL) derived from the first 24 months of mission science data with 1873 sources detected and characterized in the 100 MeV to 100 GeV range. 1017 of 1873 sources at high Galactic latitude (abs(b) > 10 degrees) are associated statistically with active galactic nuclei (AGNs). Parsec-scale VLBI measurements play an important role in characterizing the nature of the candidate AGNs by providing crucial extra information to improve the probability of correct identification - VLBI filters out objects which do not host strong compact jets at parsec scale. We are carrying out regular VLBI monitoring of 450+ compact extragalactic sources using Deep Space Network (DSN) 34-meter antennas over intercontinental baselines simultaneously at 8 and 32 GHz. In addition to precision astrometric measurements of AGN compact cores used to maintain the JPL extragalactic reference frame, this program has the potential to provide regular simultaneous flux density measurements at 8 and 32 GHz with precision level of ~20%. By providing measurements on both East-West and North-South baselines with large antennas and Gbit/s recording capability, our program can probe sources down to a flux limit of 30 mJy (10-sigma), potentially increasing the sample to a fainter population of sources. In these regards, our program complements well existing northern and southern hemisphere VLBI monitoring programs, by providing flux measurements at 32 GHz, covering a fainter population sample, and by filling the gap for sources in the -20 to -45 degree declination range. Further, our program also provides additional flexibility for

ABP 501, a U.S.A. Food and Drug Administration- and European Medicines Agency-approved biosimilar, is highly similar to adalimumab in structure, function and pharmacokinetics. To demonstrate similarity in efficacy, safety and immunogenicity of ABP 501 vs. adalimumab for moderate-to-severe plaque psoriasis (clinical trial: NCT01970488). Patients were randomized (1 : 1) to receive ABP 501 or adalimumab 40 mg every 2 weeks for 16 weeks. At week 16, patients with ≥ 50% improvement from baseline in Psoriasis Area and Severity Index (PASI) score were eligible to continue to week 52. Patients receiving ABP 501 continued; adalimumab patients were rerandomized (1 : 1) to continue adalimumab or undergo a single transition to ABP 501. Key efficacy assessments included percentage PASI improvement from baseline, PASI responders and mean change in affected body surface area from baseline to weeks 16, 32 and 50. Safety was monitored via adverse events (AEs) and antidrug antibodies (ADAs) were assessed. A total of 308 patients were rerandomized at week 16 (ABP 501/ABP 501, n = 152; adalimumab/adalimumab, n = 79; adalimumab/ABP 501, n = 77). PASI percentage improvements from baseline were similar across groups for weeks 16, 32 and 50 (range: 85·8-88·2%), with no significant differences detected across groups in percentages of PASI 50, 75, 90 and 100 responders. Changes from baseline in percentage body surface area affected were similar across groups and time points. No new safety signals were detected. AEs were balanced between groups. Percentages of patients with binding and neutralizing ADAs were similar across treatments. ABP 501 and adalimumab have similar clinical efficacy, safety and immunogenicity profiles over 52 weeks, including after single transition, in this patient population. © 2017 British Association of Dermatologists.

Kato Noriko

2004-02-01

Full Text Available Abstract Background A reference range for the birthweight of multiple births neonates is necessary for the assessment for intrauterine growth. Methods Pairs of multiple births were identified by birthplace, the ages of the parents, gestational age, and the year and month of birth. We studied a total of 32,232 livebirth-livebirth pairs of twins, 1894 triplet live births, and 206 quadruplet live births. Results The median birthweight of males, taking gestational age into account, was ca. 0.05 kg–0.1 kg heavier than that of females. Compared to singleton neonates, the median birthweight of twins was ca. 0.15 kg smaller at the gestational age of 34 weeks, increasing to ca. 0.5 kg at 42 weeks of gestation. As for birth order, the mean birthweight of the first-born twin was heavier than that of the second-born. The standard deviation of birthweight was larger for second-born twins. The birthweight of twins from multiparous mothers was greater than those from primiparous mothers. The median birthweight according to gestational age was found to be the greatest in twins, lower in triplets and the lowest in quadruplets. In triplets, the 50th percentile was 0.08 kg heavier in boys than for girls. Conclusion Our results can be used for assessment of birthweight of multiple births in Japan.

Purpose: Studies have shown a potential benefit of brachytherapy in preventing restenosis. However, the effects of intravascular radiation on arterial healing have not been well-established. The purpose of this study was to explore the histologic changes following placement of β-emitting radioactive stents in arteries focusing on intimal responses and endothelialization. Methods and Materials: 3.0-mm β-emitting 32 P stents (6-μCi and 24-μCi) were placed in rabbit iliac arteries with nonradioactive stents serving as controls. Animals were euthanized at 3 months and histologic assessment, morphometry, and analysis of endothelialization were performed. Results: The lumen areas of 24-μCi stents (4.24 ± 0.22 mm 2 , p 2 , p 2 ). The mean lumen percent stenosis was 11.4 ± 3.0% in the 24-μCi stents (p 32 P β-emitting stents reduce neointimal growth, but healing is incomplete with poor endothelialization at 3 months. Longer-term studies with complete arterial healing are needed to determine whether there is sustained neointimal inhibition by stent-delivered brachytherapy

The author presents a method to study the influence of various factors of the absorption of 32 P applied under the form of phosphates by a plant cultivated in conditions ensuring a normal development. Experiments provided indications on leaf absorption and 32 P transport by pumpkin leaves: phosphor 32 is absorbed and then quickly transported into the different organs of the plant (24 hours after treatment, it is present in aerial and underground parts), the quantity of absorbed phosphor increases with phosphor concentration in the applied solution, atmosphere humidity is an important factor for phosphor penetration into the leaves, plants absorb phosphor in darkness as well as in light, and the absorption of phosphor is not modified when applied with low glucose concentrations [fr

We report a retrospective study of 15 patients with prostate carcinoma and diffuse bone metastases treated with sodium /sup 32/P for palliation of pain at Downstate Medical Center and Kings County Hospital from 1973 to 1978. The response rates, duration of response, and toxicities are compared with those of other series of patients treated with /sup 32/P and with sequential hemibody irradiation. The response rates and duration of response are similar with both modalities ranging from 58 to 95% with a duration of 3.3 to 6 months with /sup 32/P and from 75 to 86% with a median duration of 5.5 months with hemibody irradiation. There are significant differences in the patterns of response and in the toxicities of the two treatment methods. Both methods cause significant bone marrow depression. Acute radiation syndrome, radiation pneumonitis, and alopecia are seen with sequential hemibody irradiation and not with /sup 32/P, but their incidence can be reduced by careful treatment planning. Hemibody irradiation can provide pain relief within 24 to 48 h, while /sup 32/P may produce an initial exacerbation of pain. Lower hemibody irradiation alone is less toxic than either upper hemibody irradiation or /sup 32/P treatment.

Background: Amifostine is a radioprotective drug applied to reduce acute radiation toxicity during a course of conventionally fractionated radiotherapy. In the present study, amifostine was used in patients undergoing adjuvant radiochemotherapy for rectal cancer. It was described previously that additional application of amifostine led to less acute skin and bowel toxicity. The present study was aimed to determine whether amifostine has an influence on the amount of residual chromosomal damage. Material and Methods: Peripheral lymphocytes of twelve rectal cancer patients who had undergone postoperative radiochemotherapy 2-3 years ago were investigated for residual chromosomal damage using 24-color fluorescence in situ hybridization (24-color FISH). All twelve patients had received a total dose of 55.8 Gy in conventional fractionation of 1.8 Gy and a 120-h continuous infusion of 5-fluorouracil (5-FU) chemotherapy (1,000 mg/m 2 per day) in the 1st and 5th week of irradiation. Seven out of twelve patients had been given additional amifostine on chemotherapy days (500 mg total dose as short i.v. infusion immediately prior to the daily radiation fraction). Cultivation of lymphocytes and 24-color FISH were performed according to standard protocols. 100 metaphases per patient were analyzed for chromosomal aberrations in a blind study. Results: Analysis of the average number of breaks per mitosis (B/M) revealed an increased amount of residual chromosomal damage in the group treated with amifostine (0.65 B/M [0.32-0.97]) as well as in those treated without amifostine (0.76 B/M [0.31-1.25]). Also the average number of cells containing aberrations per 100 analyzed metaphases was similar (with amifostine: 22.1 [13-32] vs. 24.4 [13-35] without amifostine). The aberration types, occurring as simple translocations, reciprocal translocations, breaks, dicentrics, inversions, rings and complex chromosomal rearrangements, did not show any specific accumulation in one or the other

Forty-one preterm infants (gestational age [median] 26 weeks, age [median] 21 days) on FiO 2  >0.21 receiving noninvasive respiratory support were subjected to A-FiO 2 using 3 SpO 2 target ranges (86%-94%, 88%-92%, or 89%-91%) in random order for 24 hours each. Before switching to the next target range, SpO 2 was manually controlled for 24 hours (washout period). The primary outcome was the time spent within the clinically set alarm limits of 86%-94%. The percent time within the 86%-94% SpO 2 alarm range was similar for all 3 A-FiO 2 target ranges (74%). Time spent in hyperoxemia was not significantly different between target ranges. However, the time spent in severe hypoxemia (SpO 2  target ranges of A-FiO 2 (88%-92%; 1.9%, 89%-91%; 1.7%) compared with the wide target range (86%-94%; 3.4%, P target range.

A 32-year medical follow-up of Manhattan project plutonium workers

International Nuclear Information System (INIS)

Voelz, G.L.; Hempelmann, L.H.; Lawrence, J.N.P.; Moss, W.D.

1979-01-01

Twenty-six male subjects who worked with plutonium during World War 2 under extraordinarily crude conditions have been followed medically for a period of 32 yr. Inhalation was the primary mode of plutonium exposure. Current estimates of the systematic plutonium depositions in these individuals range from 7 to 230 nCi. Eleven individuals have dispositions greater than 40 nCi, the current maximum permissible body burden for workers. Two individuals in the group have died: one due to myocardial infarction and the other due to injuries sustained in an automobile-pedestrian accident. This mortality rate is about 50% of expected deaths based on United States white male rates. All 24 living subjects were re-examined in the period of 1975-78. No cases of cancer were diagnosed in the group except for two skin cancers that have no history or basis that relate them to plutonium exposure. The diseases and physical changes noted in the group are characteristic of a male population in their 50s and 60s. This study yields no evidence suggesting that adverse health effects have resulted from the 32 yr of exposure to the internally deposited plutonium. (author)

Full Text Available Abstract Purpose The present study aimed at evaluating the efficacy of Raltitrexed, a specific thymidilate synthase inhibitor, in patients with advanced colorectal cancer (ACC in relapse (>8 weeks after a prior response or disease stabilization to first-line chemotherapy combination with lrinotecan+5-Fluorouracil (5-FU+Leucovorin (LV. Methods Twenty-five patients with metastatic ACC entered; 17 males/8 females, median age 61 (range: 47–70, median Karnovsky PS: 80 (70–90, and sites of metastases; liver: 21, lung: 4, lymph nodes: 7, peritoneal: 5 and a life expectancy of at least 3 months, were entered in the present pilot study. All patients had progressed after prior chemotherapy with lrinotecan+5-FU+LV. Raltitrexed was administered at a dose of 3 mg/m2 i.v. every 21 days. Results Three patients (12% achieved a partial response (PR, 8 (32% had stable disease (SD, and the remaining 14 (56% developed progressive disease (PD. Median time-to-progression (TTP was 5.5 months (range, 2–8.5, and median overall survival (OS 8 months (range, 4.0–12.5. Toxicity was generally mild; it consisted mainly of myelosuppression; neutropenia grade 1–2: 52%-grade 3: 28%, and anemia grade 1–2 only: 36%. Mild mucositis grade 1–2 occured in 13.5% of patients and was the principal non-hematologic toxicity. Conclusion Response to treatment with Raltitrexed is limited in patients with ACC failing after an initial response or non-progression to the weekly lrinotecan+5-FU+LV combination. However, it appears that a limited number of patients with PR/SD may derive clinical benefit, but final proof would require a randomized study.

Thyroid ultrasound is a non-invasive imaging tool and provides good evaluation of thyroid anatomy, location, vascularisation, and echogenicity. The aim of this study was to assess thyroid function and thyroid volume in extremely preterm infants born before 28 weeks' gestation evaluated at 36 weeks' corrected gestational age (CGA) compared to term infants' normative data in the literature. In this largest prospective UK study of extremely premature infants born at less than 28 weeks' gestation, thyroid volume measurement was assessed at 36 weeks' CGA. Fifty-five extremely preterm infants (28 males) who were born before 28 weeks' gestation were recruited to the study. All infants had ultrasound assessment of the thyroid gland at 36 weeks' CGA. We also prospectively measured thyroid stimulating hormone (TSH) and free thyroxine (FT 4 ) in all infants at the time of recruitment (within 5 days of birth), at days 14, 21, and 28, and at 36 weeks' CGA. The mean thyroid volume was measured at 0.57 mL (SD ±0.18). There was no association between mean thyroid volume and thyroid function (TSH or FT 4 ). No associations were found between mean thyroid volume and gestation or birth weight in these infants. Our findings provide a reference range with a mean thyroid volume of 0.57 mL (SD ±0.18) in this extremely preterm age group if less than 28 weeks' gestation. Thyroid volume at birth can vary from country to country due to variations in iodine intake as well as gestational age.

complications associated with prematurity of infants with less than 32 weeks of gestation. METHODS: It was done a prospective cohort study. All preterm infants with a gestational age between 25 and 31 weeks and 6 days, born alive without congenital anomalies and admitted to the NICU between August 1st, 2009 and October 31st, 2010 were included. Newborns were stratified into three groups: G25, 25 to 27 weeks and 6 days; G28, 28 to 29 weeks and 6 days; G30, 30 to 31 weeks and 6 days, and they were followed up to 28 days. Survival at 28 days and complications associated with prematurity were evaluated. Data were analyzed statistically by c² test, analysis of variance, Kruskal-Wallis test, odds ratio with confidence interval (CI and multiple logistic regression, with significance set at 5%. RESULTS: The cohort comprised 198 preterm infants (G25=59, G28=43 and G30=96. The risk of death was significantly higher in G25 and G28 compared to G30 (RR=4.14, 95%CI 2.23-7.68 and RR=2.84, 95%CI: 1.41-5.74. Survival was 52.5%, 67.4% and 88.5%, respectively. Survival was greater than 50% in preterm >26 weeks and birth weight >700 g. Neonatal morbidity was inversely proportional to gestational age, except for necrotizing enterocolitis and leukomalacia, which did not differ among groups. Logistic regression showed that pulmonary hemorrhage (OR=3.3, 95%CI 1.4-7.9 and respiratory distress syndrome (OR=2.5, 95%CI 1.1-6.1 were independent risk factors for death. There was a predominance of severe hemorrhagic brain lesions in G25. CONCLUSION: Survival above 50% occurred in infants with a gestational age of more than 26 weeks and >700 g birth weight. Pulmonary hemorrhage and respiratory distress syndrome were independent predictors of neonatal death. It is necessary to identify the best practices to improve the survival of extreme preterm infants.

Cesarean section rates continue to increase globally. Prediction of intrapartum cesarean section could lead to preventive measures. Our aim was to assess the association between sonographically measured cervical length at 37 weeks of gestation and cesarean section among women planning a vaginal birth. The population was women with a low-risk pregnancy or with gestational diabetes. This was a prospective cohort study conducted in a tertiary referral hospital in Sydney, Australia. In all, 212 women with a low-risk pregnancy or with gestational diabetes were recruited including 158 nulliparous and 54 parous women. Maternal demographic, clinical and ultrasound characteristics were collected at 37 weeks of gestation. Semi-Bayesian logistic regression and Markov chain Monte Carlo simulation were used to assess the relationship between cervical length and cesarean section in labor. Rates of cesarean section were 5% (2/55) for cervical length ≤20 mm, 17% (17/101) for cervical length 20-32 mm, and 27% (13/56) for cervical length >32 mm. These rates were 4, 22 and 33%, respectively, in nulliparous women. In the semi-Bayesian analysis, the odds ratio for cesarean section was 6.2 (95% confidence interval 2.2-43) for cervical length 20-32 mm and 10 (95% confidence interval 4.8-74) for cervical length >32 mm compared with the lowest quartile of cervical length, after adjusting for maternal age, parity, height, prepregnancy body mass index, gestational diabetes, induction of labor, neonatal sex and birthweight centile. Cervical length at 37 weeks of gestation is associated with intrapartum cesarean section. © 2018 Nordic Federation of Societies of Obstetrics and Gynecology.

Full Text Available Hydrogen can relieve tissue-damaging oxidative stress, inflammation and apoptosis. Injection of hydrogen-rich saline is an effective method for transporting molecular hydrogen. We hypothesized that hydrogen-rich saline would promote the repair of spinal cord injury induced by Allen′s method in rats. At 0.5, 1, 2, 4, 8, 12 and 24 hours after injury, then once daily for 2 weeks, 0.25 mL/kg hydrogen-rich saline was infused into the subarachnoid space through a catheter. Results at 24 hours, 48 hours, 1 week and 2 weeks after injury showed that hydrogen-rich saline markedly reduced cell death, inflammatory cell infiltration, serum malondialdehyde content, and caspase-3 immunoreactivity, elevated serum superoxide dismutase activity and calcitonin gene-related peptide immunoreactivity, and improved motor function in the hindlimb. The present study confirms that hydrogen-rich saline injected within 2 weeks of injury effectively contributes to the repair of spinal cord injury in the acute stage.

Purpose: To evaluate 2-dimensional strain imaging (SI) for the detection of subclinical myocardial dysfunction during and after radiation therapy (RT). Methods and Materials: Forty women with left-sided breast cancer, undergoing only adjuvant RT to the left chest, were prospectively recruited. Standard echocardiography and SI were performed at baseline, during RT, and 6 weeks after RT. Strain (S) and strain rate (Sr) parameters were measured in the longitudinal, circumferential, and radial planes. Correlation of change in global longitudinal strain (GLS % and Δ change) and the volume of heart receiving 30 Gy (V30) and mean heart dose (MHD) were examined. Results: Left ventricular ejection fraction was unchanged; however, longitudinal systolic S and Sr and radial S were significantly reduced during RT and remained reduced at 6 weeks after treatment [longitudinal S (%) −20.44 ± 2.66 baseline vs −18.60 ± 2.70* during RT vs −18.34 ± 2.86* at 6 weeks after RT; longitudinal Sr (s{sup −1}) −1.19 ± 0.21 vs −1.06 ± 0.18* vs −1.06 ± 0.16*; radial S (%) 56.66 ± 18.57 vs 46.93 ± 14.56* vs 49.22 ± 15.81*; *P<.05 vs baseline]. Diastolic Sr were only reduced 6 weeks after RT [longitudinal E Sr (s{sup −1}) 1.47 ± 0.32 vs 1.29 ± 0.27*; longitudinal A Sr (s{sup −1}) 1.19 ± 0.31 vs 1.03 ± 0.24*; *P<.05 vs baseline], whereas circumferential strain was preserved throughout. A modest correlation between S and Sr and V30 and MHD was observed (GLS Δ change and V30 ρ = 0.314, P=.05; GLS % change and V30 ρ = 0.288, P=.076; GLS Δ change and MHD ρ = 0.348, P=.03; GLS % change and MHD ρ = 0.346, P=.031). Conclusions: Subclinical myocardial dysfunction was detected by 2-dimensional SI during RT, with changes persisting 6 weeks after treatment, though long-term effects remain unknown. Additionally, a modest correlation between strain reduction and radiation dose was observed.

The purpose of this study was to determine the effects of short-term plyometric training interposed with 24 or 48 hours of rest between training sessions on explosive and endurance adaptations in young soccer players. A total of 166 players, between 10 and 17 years of age, were randomly divided into 3 groups: a control group (CG; n = 55) and 2 plyometric training groups with 24 hours (PT24; n = 54) and 48 hours (PT48; n = 57) of rest between training sessions. Before and after intervention, players were measured in squat jump, countermovement jump, 20 (RSI20) cm drop jump reactive strength index, broad long jump, 20-m sprint time, 10 × 5-m agility time, 20-m multistage shuttle run test, and sit-and-reach test. The plyometric training program was applied during 6 weeks, 2 sessions per week, with a load from 140 to 260 jumps per session, replacing some soccer-specific drills. After intervention, the CG did not show significant performance changes. PT24 and PT48 groups showed a small-to-moderate significant improvement in all performance tests (p plyometric drills should not be conducted on consecutive days, the study shows that plyometric training applied twice weekly on consecutive or nonconsecutive days results in similar explosive and endurance adaptations in young male soccer players.

Full Text Available Many people find that their sleep is restricted or disturbed by social obligations, including work. Sleep phase delays can affect an individual’s circadian rhythms on the following day and cause daytime sleepiness and/or poor performance. In this study, to examine weekly variations in sleep patterns, we analyzed sleep data for seven-day periods (from Sunday to Saturday that had been collected from 2914 subjects (aged 20–79 years over a total of 24,899 subject-weeks using contactless biomotion sensors. On the weekend, the subjects’ mean sleep midpoint, bedtime, and wake-up time were delayed by 40, 26 and 53 min, respectively, compared with those seen on weekdays. In addition, on weekdays, the mean difference between the maximum and median sleep midpoint ranged from 35 to 47 min among the subjects in their 20 s–70 s. The weekend delay and weekday variation in the subjects’ sleep patterns tended to decrease with age. This study detected sleep pattern disturbances on both weekdays and weekends. The serial changes in weekday bedtimes detected in this study suggest that sleep habits are influenced by changes in the temporal patterns of social activities/duties. We need further study the advantages of getting extra sleep and the disadvantages of sleep pattern disturbances in daily lifestyle.

Broiler chickens often make limited use of the free-range area. Range use is influenced by type of shelter available. Range use may possibly be improved by a more gradual transition from the house to the range and by using dark brooders (secluded warm, dark areas in the home pen) that mimic aspects of a broody hen and possibly reduce fearfulness. The aim of this study was to assess effects of dark brooders on fearfulness, free-range use and behaviour later in life. Another aim was to test the chickens' preference for shelter type and the effects of overhangs outside of the pop holes to provide a gradual transition to the range. Three production rounds, each with 440 Sasso broiler chickens (110/group), were completed. Chicks were housed indoors from days 0 to 25; per round, two groups had access to a dark brooder, whereas the other two groups had conventional IR lamps. Fearfulness was assessed by the open field (OF) and tonic immobility (TI) tests on days 22 to 24 on 25 chicks/group per round. Birds were then moved to four mobile houses from which they could access both grassland with artificial shelter (AS) and short rotation coppice (SRC). Two of the houses had overhangs extending from the pop holes; these were switched between the four houses weekly. Free-range use and behaviour were observed three times daily from Monday to Friday. Dark brooders did not affect results from the OF or TI test, except for jumps in the OF test which tended to occur less often in brooded chicks. Neither dark brooders (34.9% without v. 31.7% with brooder) nor overhangs (32.5% without v. 34.1% with overhangs) influenced the percentage of chickens outside. Chickens showed a clear preference for SRC, range use increased over time in SRC, and more birds ranged farther from the house in SRC. Behaviours of chickens observed outside were mainly influenced by shelter type, age of the birds and distance from the house. Locomotion tended to occur more in the presence of overhangs. Overall

Purpose: Weekly paclitaxel, concurrent radiation, and androgen deprivation (ADT) were evaluated in patients with high-risk prostate cancer (PC) with or without prior prostatectomy (RP). Methods and Materials: Eligible post-RP patients included: pathological T3 disease, or rising prostate-specific antigen (PSA) {>=}0.5 ng/mL post-RP. Eligible locally advanced PC (LAPC) patients included: 1) cT2b-4N0N+, M0; 2) Gleason score (GS) 8-10; 3) GS 7 + PSA 10-20 ng/mL; or 4) PSA 20-150 ng/mL. Treatment included ADT (4 or 24 months), weekly paclitaxel (40, 50, or 60 mg/m{sup 2}/wk), and pelvic radiation therapy (total dose: RP = 64.8 Gy; LAPC = 70.2 Gy). Results: Fifty-nine patients were enrolled (LAPC, n = 29; RP, n = 30; ADT 4 months, n = 29; 24 months, n = 30; whites n = 29, African Americans [AA], n = 28). Baseline characteristics (median [range]) were: age 67 (45-86 years), PSA 5.9 (0.1-92.1 ng/mL), GS 8 (6-9). At escalating doses of paclitaxel, 99%, 98%, and 95% of doses were given with radiation and ADT, respectively, with dose modifications required primarily in RP patients. No acute Grade 4 toxicities occurred. Grade 3 toxicities were diarrhea 15%, urinary urgency/incontinence 10%, tenesmus 5%, and leukopenia 3%. Median follow-up was 75.3 months (95% CI: 66.8-82.3). Biochemical progression occurred in 24 (41%) patients and clinical progression in 11 (19%) patients. The 5- and 7-year OS rates were 83% and 67%. There were no differences in OS between RP and LAPC, 4- and 24-month ADT, white and AA patient categories. Conclusions: In addition to LAPC, to our knowledge, this is the first study to evaluate concurrent chemoradiation with ADT in high-risk RP patients. With a median follow-up of 75.3 months, this trial also represents the longest follow-up of patients treated with taxane-based chemotherapy with EBRT in high-risk prostate cancer.

The superiority of radiopharmaceutical compare to the other techniques of medical services, especially for diagnosis and therapy of several deadly diseases such as cancer, shows that this technique is more specific and accurate. P-32-Glass microsphere (P-32 GMS) is one of the radiopharmaceuticals developed recently for therapy using internal radiation method for several malignant cancers, such as hepatic cancer. The P-32 GMS was prepared by irradiating P-31 GMS with neutron at a nuclear reactor, then the preparation was injected to the cancerous infected area. To make easy injection, it needs suspension agent that was including PVP, dextrose and saline with a composition of 16% PVP - 50% dextrose - saline as 2 : 3 : 3 (v/v/v). As microsphere size should be maintained at 40-60 μm, the injection needle was selected properly in order to remain the particle size of P-32 GMS unchanged when the friction occurs between microspheres and the inside surfaces of the needle. The injection needle used was needle produced by BD with a typical size of 20 G1 Tw. Biodistribution studies were carried out after 1, 3, 5 and 24 hour of injection. Experimental results for 1, 3 and 24 hour post-injection studies showed that 100% activity of P-32 GMS was accumulated at the injected area. For 5 hour post-injection study, accumulation of P-32 GMS activity was also found at stomach besides the injected area, but it was presumed as working error

To characterize the performance of cemented total knee replacement (TKR) in dogs. Preclinical research study. Skeletally mature, male Hounds (25-30 kg; n=24) with no preexisting joint pathology. Dogs had unilateral cemented TKR and were evaluated at 6, 12, 26, or 52 weeks (6 dogs/time point) by radiography, bone density analysis, visual gait assessment, and direct measurement of thigh circumference and stifle joint range of motion as indicators of functional recovery. At study end, the stability of the cemented tibial component was determined by destructive mechanical testing. Joint stability was excellent in 16 dogs (67%) and good in 8 dogs. None of the tibial components had evidence of migration or periprosthetic osteolysis whereas 1 femoral component was loose at 52 weeks. There was an early and significant decrease in tibial bone density, likely because of disuse of the operated limb. Dogs returned to full activity by 12 weeks. The tibial cement-bone interface maintained its strength over 52 weeks. Cement provides stable fixation of the tibial component in canine TKR. Cemented TKR yields adequate clinical function and stifle joint excursion in the dog. Clinical studies are needed to determine the long-term fate of cemented TKR implants, to assess the influence of implant design on implant fixation and wear, and to obtain objective functional data.

Wonnabussapawich, P, Hamlin, MJ, Lizamore, CA, Manimmanakorn, N, Leelayuwat, N, Tunkamnerdthai, O, Thuwakum, W, and Manimmanakorn, A. Living and training at 825 m for 8 weeks supplemented with intermittent hypoxic training at 3,000 m improves blood parameters and running performance. J Strength Cond Res 31(12): 3287-3294, 2017-We aimed to investigate the effect of an 8-week low-altitude training block supplemented with intermittent hypoxic training, on blood and performance parameters in soccer players. Forty university-level male soccer players were separated into altitude (n = 20, 825 m) or sea-level (n = 20, 125 m) groups. Before (1-2 days ago) and after (1 and 14 days later) training, players were asked to give a resting venous blood sample and complete a series of performance tests. Compared with sea level, the altitude group increased erythropoietin, red blood cell (RBC) count, and hematocrit 1 day after training (42.6 ± 24.0%, 1.8 ± 1.3%, 1.4 ± 1.1%, mean ± 95% confidence limits (CL), respectively). By 14 days after training, only RBC count and hemoglobin were substantially higher in the altitude compared with the sea-level group (3.2 ± 1.8%, 2.9 ± 2.1% respectively). Compared with sea level, the altitude group 1-2 days after training improved their 50-m (-2.9 ± 1.4%) and 2,800-m (-2.9 ± 4.4%) run times and demonstrated a higher maximal aerobic speed (4.7 ± 7.4%). These performance changes remained at 14 days after training with the addition of a likely higher estimated V[Combining Dot Above]O2max in the altitude compared with the sea-level group (3.2 ± 3.0%). Eight weeks of low-altitude training, supplemented with regular bouts of intermittent hypoxic training at higher altitude, produced beneficial performance improvements in team-sport athletes, which may increase the viability of such training to coaches and players that cannot access more traditional high altitude venues.

Rapid decline in glomerular filtration rate during the first weeks following heart transplantation

Hornum, M; Andersen, M; Gustafsson, F

2011-01-01

We hypothesized that a decrease in renal function is seen immediately after heart transplantation (HTX) with little recovery over time. Twelve consecutive patients had their glomerular filtration rate (GFR) measured using (51)Cr-ethylenediaminetetraacetic acid (EDTA) measured GFR (mGFR) before...... transplantation and at 1, 2, 3, and 26 weeks after transplantation. The mGFR decreased by 28% and 24% during the first 3 and 26 weeks, respectively, with mean blood cyclosporine concentration as an independent risk factor for the decrease in mGFR. The identification of cyclosporine A (CsA) as the most important...

This study evaluates the validity of Doppler-detected fetal movement by a commercially available monitor and investigates whether characteristics of maternal body habitus and the intrauterine environment affect its performance. Fetal movement was evaluated in normal pregnancies using both ultrasound visualization and a fetal actocardiograph (Toitu MT320; Tofa Medical Inc., Malvern, PA). Data were collected for 32 min on 34 fetuses stratified by gestational age (20-25 weeks; 28-32 weeks; 35-39 weeks). Fetal and maternal characteristics were recorded. Comparisons between ultrasound-detected trunk and limb movements and actograph records were conducted based both on 10-s time intervals and on detection of individual movements. Time-based comparisons indicated agreement between ultrasound and actograph 94.7% of the time; this association rose to 98% when movements of less than 1 s duration were excluded. Individual movements observed on ultrasound were detected by the actograph 91% of the time, and 97% of the time when brief, isolated movements were excluded. The overall kappa value for agreement was 0.88. The actograph was reliable in detecting periods of quiescence as well as activity. These findings did not vary by gestational age. The number of movements detected by the actograph, but not the single-transducer ultrasound, significantly increased over gestation. Maternal age, parity, weight, height, or body mass index were not consistently associated with actograph validity. Characteristics of the uterine environment, including placenta location, fetal presentation, and amniotic fluid volume also did not affect results. The Toitu actograph accurately detects fetal movement and quiescence from as early as 20 weeks gestation and has utility in both clinical and research settings. Actographs are most useful for providing objective and quantifiable measures of fetal activity level, including number and duration of movements, while visualization through ultrasound is

Purpose: To evaluate the efficacy and toxicity of weekly paclitaxel with concurrent radiotherapy followed by adjuvant chemotherapy (AC) in patients with locally advanced nasopharyngeal carcinoma (NPC). Methods and materials: Between 2004 and 2007, 54 patients with locally advanced NPC were included in this protocol. Patient characteristics: median age 48; 69% male; 52% World Health Organization (WHO) III; 50% stage III, 50% stage IV. The patients underwent a course of definitive conventional radiotherapy (70 Gy in 7 weeks with 2 Gy/fraction), with concurrent weekly paclitaxel 35 mg/m 2 from the first to the sixth week of radiation. AC was started 4 weeks after the end of the radiotherapy (RT), paclitaxel 135 mg/m 2 on day 1 and cisplatin 30 mg/m 2 on days 1-3 were administered every 4 weeks for two cycles. Results: Median follow-up was 32 months. Eighty-five percentage of complete response and 15% partial response were achieved at the time of one month after AC. The 3-year actuarial rate of local regional control was 86%; distant metastases-free survival, progression-free survival and overall survival at 3 years were 81%, 69% and 76%, respectively. Forty-nine (91%) patients completed six courses of concurrent chemotherapy with weekly paclitaxel, and 4 (7%) patients delayed at the second cycle of AC. No patient developed severe acute toxicities. Conclusions: Weekly paclitaxel with concurrent RT followed by AC is a potentially effective and toxicity tolerable method for locally advanced NPC. Further studies are needed to identify the optimal dose of weekly paclitaxel in this strategy.

2013-01-01

The minimum between solar cycles 23 and 24 was quite unusual compared with other minima for which detailed data are available and this pointed to the possibility that cycle 24 will be unusual. Cycle 24 is almost at its maximum now and we take this opportunity to compare and contrast the solar rotation rate and zonal flows between the two cycles. We find that the rotation rate during cycle 24 is slightly lower than that during cycle 23. Additionally we find that the poleward branch of the zonal flow that is believed to be the harbinger of the next solar cycle is very week in cycle 24.

Full Text Available Introduction: Neonatal jaundice is a common condition observed in approximately two-thirds of all newborns in the first postnatal week of life. In most cases it is benign and no treatment is required. However, in severe cases, pathological jaundice can lead to acute bilirubin encephalopathy and kernicterus. Aim: To characterise the main predisposing factors as well as the treatment modalities of babies with significant neonatal jaundice presenting in the first 24 hours of life. Materials and Methods: We conducted a retrospective, observational study of all babies admitted to the neonatal unit at the Royal hospital in Oman in the period between 1st January 2014 and 31st December 2014 and treated for significant hyperbilirubinaemia presenting in the first 24 hours of life. Patients were selected from the Royal Hospital neonatal admission registry. A total of 125 patients records were analysed for the sake of the study. Results: The mean gestational age was 34 weeks and the mean birth weight was 2070 grams. Male to female ratio was 1:1.2. About 30 (45% of the males and 15 (26% of the females had Glucose-6-Phosphate Dehydrogenase (G6PD deficiency. Blood group of the babies was A 42 (33.6%, B 34 (27.2%, AB 4 (3.2% and O 45 (36%. About 4.8% were Rhesus negative. In all 27 (21.6% of the babies tested positive for Direct Coombs Test. The maximum Total Serum Bilirubin (TSB in the first 24 hours of life was 130±65 µmol/L and the maximum TSB anytime during the admission was 215±80 µmol/L. About 88 (70% of the babies received standard phototherapy and 37 (30% received intensive phototherapy. Intravenous Immunoglobulin (IVIG in addition to phototherapy was administered in 21 (17% of the babies. None of the babies required exchange transfusion. Conclusion: It was observed that the most common predisposing factors for significant neonatal jaundice presenting in the first 24 hours of life were prematurity, G6PD deficiency and isoimmune hemolytic disease

Females and eggs of Toxorhynchites r. rutilus were labeled with 32 P by feeding fourth-stage larvae 32 P labeled Aedes aegypti larvae. Eggs from females up to 3 weeks in age had detectable levels of radioactivity and individual eggs contained ca. 0.3% of the mother's total radioactivity. Comparisons of labeled and unlabeled females in indoor and outdoor cage tests indicated that survival and fecundity of the 2 groups were approximately equal. No differences were noted for dispersal and fecundity of labeled and control females released in field tests. The 32 P-labeled Tx. r. rutilus females behave similarly to unlabeled females, and this method of radiolabeling provides a sound tool for tracking laboratory-reared females released into an area with an indigenous population

Sacubitril/valsartan (LCZ696), a first-in-class angiotensin receptor-neprilysin inhibitor, demonstrated significant reductions in office and 24 h ambulatory blood pressure (BP) over 8 weeks in Asian patients with hypertension. This 52-week extension to the 8-week core study was aimed at evaluating the long-term safety, tolerability and efficacy of sacubitril/valsartan. Patients who completed an 8-week randomized study (the core study) were enrolled in this 52-week open-label study and received sacubitril/valsartan 200 mg QD. The sacubitril/valsartan dose was uptitrated to 400 mg QD if BP was uncontrolled (>140/90 mm Hg) after 4 weeks. Subsequently, in patients with uncontrolled BP, treatment was intensified every 4 weeks with amlodipine 5-10 mg followed by hydrochlorothiazide 6.25-25 mg. Of the 341 patients enrolled, 7 (2.1%) discontinued the study drug due to adverse events (AEs). The incidence of AEs and serious AEs were 63.9 and 3.8%, respectively, and no deaths were reported in this study. The most frequent AEs were nasopharyngitis (18.2%) and dizziness (8.8%). Events that were potentially indicative of low BP were infrequent. One patient reported mild transient angioedema (lasting 2.5 h) that resolved without treatment but led to study drug discontinuation. The sacubitril/valsartan-based regimen provided clinically significant mean sitting systolic BP (msSBP) and mean sitting diastolic BP (msDBP) reductions from baseline (-24.7/-16.2 mm Hg). The overall BP control, msSBP and msDBP response rates were 75.3, 90.6 and 87.6%, respectively. Long-term use of sacubitril/valsartan was generally safe and well-tolerated in patients with hypertension and provided significant BP reductions from baseline.

Full Text Available Efficacy of antenatal corticosteroids before 25 weeks of gestation is unclear.To assess and compare neonatal outcomes following ANC exposure at 22, 23 and 24 weeks of gestation by conducting systematic review and meta- analysis.A systematic review of randomised controlled trials (RCT and non-RCTs reporting on neonatal outcomes after exposure to ANC up to 246 weeks of gestation using the Cochrane systematic review methodology. Databases Pubmed, CINAHL, Embase, Cochrane Central library, and online abstracts of conference proceedings including the Pediatric Academic Society (PAS were searched in Feb 2017. Primary outcome was in-hospital mortality defined as death before discharge during the first admission. Secondary outcomes included severe intraventricular hemorrhage (IVH> grade III and IV/or periventricular leukomalacia (PVL, necrotising enterocolitis (NEC >stage II and chronic lung disease (CLD. Meta-analysis was performed using a random-effects model. The level of evidence (LOE was summarised using the GRADE guidelines.There were no RCTs; 8 high quality non-RCTs were included in the review. Meta-analysis showed reduction in mortality [N = 10109; OR = 0.47(0.39-0.56, p<0.00001; LOE: Moderate] and severe IVH and PVL [N = 5084; OR = 0.71(0.61-0.82, p<0.00001; LOE: Low] after exposure to ANC in neonates born <25 weeks. There was no significant difference in CLD [N = 4649; OR = 1.19(0.85-1.65 p = 0.31; LOE: Low] and NEC [N = 5403; OR = 0.95 (0.76-1.19 p = 0.65; LOE: Low]. Mortality was comparable in neonates born at 22, 23 or 24 weeks.Moderate to low quality evidence indicates that exposure to ANC is associated with reduction in mortality and IVH/or PVL in neonates born before 25 weeks.

This study evaluated the effect of chilled followed by frozen storage on lamb quality and safety parameters. Experimental (n=360) M. longissimus lumborum (LL) were randomly sampled from the boning room of a commercial Australian abattoir, at 24 h post-mortem, and assigned to five chilled storage periods (0, 2, 4, 6 and 8 weeks) and six subsequent frozen storage periods (0, 4, 8, 12, 24 and 52 weeks). Upon completion of each storage treatment combination, corresponding LL were sub-sectioned and analysed for colour stability (0, 1, 2 and 3 days), shear force, fluid losses (purge, thaw and cooking losses), intramuscular fat content, sarcomere length, water activity and microbial load (lactic acid bacteria, Enterobacteriaceae sp., Brochothrix thermosphacta, Clostridium perfringens and Escherichia coli). LL stored chilled for 2-4 weeks prior to freezing presented superior results for shear force, display colour and low levels of spoilage microbes, correlating with good eating quality and safety following more than one year of frozen storage.

We analyzed the development of the area of the penis and erectile structures (corpora cavernosa and corpus spongiosum) and the thickness of the tunica albuginea during the fetal period (13 to 36 weeks after conception) in humans to establish normative patterns of growth. We studied 56 male human fetuses at 13 to 36 weeks after conception. We used histochemical and morphometric techniques to analyze the parameters of total penile area, area of corpora cavernosa, area of corpus spongiosum, and thickness of tunica albuginea in the dorsal and ventral regions using ImageJ software (National Institutes of Health, Bethesda, Maryland). Between 13 and 36 weeks after conception the area of the penis varies from 0.95 to 24.25 mm2. The area of the corpora cavernosa varies from 0.28 to 9.12 mm2, and the area of the corpus spongiosum varies from 0.14 to 3.99 mm2. The thickness of the tunica albuginea varies from 0.029 to 0.296 mm in the dorsal region and from 0.014 to 0.113 mm in the ventral region of the corpora cavernosa. We found a strong correlation between the total penile area, corpora cavernosa and corpus spongiosum with fetal age (weeks following conception). The growth rate was more intense during the second trimester (13 to 24 weeks of gestation) compared to the third trimester (25 to 36 weeks). Tunica albuginea thickness also was strongly correlated with fetal age and this structure was thicker in the dorsal vs ventral region.

We propose a compartmental model to describe P cycling in the root-litter mat and surface mineral soil of an Atlantic coastal forest. Considerable amounts of P accumulate in this root-litter mat, relative to available P in the underlying mineral soil. We studied the mechanisms responsible for P retention five days after addition of sup(32)P on the surface of the 02 horizon. Total sup(31)P and sup(32)P were determined in leaves, humus, mineral soil and roots. In addition, we determined sup(31)P and sup(32)P in the solution and microbial biomass of the humus material. Fluxes of sup(31)P were obtained from published data and from experimental results of sup(32)P distribution among compartments. The main fluxes taking P out from the soils solution were uptake by the microbial biomass and sorption by the humus (12.9 e 5.2 mg P m sup(-2) week sup(-1), respectively), while the mean flux into the roots was 3.1 mg P m sup(-2) week sup(-1). The main compartment responsible for P accumulation was the humus+fragments, which had the highest P content (61% of total P in the forest floor) and the longest turnover time (15.5 months).

Labelling of rice seedlings and rice plants with 32 P. Labelled rice seedlings can be used to tag insect pests that feed on. Radioactivity counting of 32 P in the endosperm and in the shoot of rice seeds that soaked for 72 hours in KH 2 32 PO 4 solution of 1 μCi/ml were 29,300 and 9,500 cpm respectively. When these labelled seedlings were grown in unlabelled medium the radioactivity in the shoot increased. It was due to the 32 P that was translocated to the shoot from the endosperm. The 32 P translocation reached maximum about one week after the seedling were grown in the unlabelled medium. Labelled seedlings could also be produced by growing 5, 10 and 15 days old seedlings hydroponically in Kimura B solution containing 32 P. Ten days after growing, the radioactivity concentration of the seedlings stem reached about 115,000; 85,000 and 170,000 cpm/mg dry weight for the 5, 10 and 15 days old seedlings respectively. For the implementation of this method, 20 ml labelled Kimura B was needed for labelling of one seedling. The seedlings should be prepared in tap water. During the growth the 32 P in the labelled seedlings was distributed throughout the plant, so that new leaves and tillers became also radioactive. (author). 5 refs

Zelenitsky, Sheryl A; Ariano, Robert E

2010-08-01

Given concerns regarding optimal therapy for serious Gram-negative infections, the goal was to characterize the pharmacodynamics of ciprofloxacin in the context of treating bloodstream infection. Data were collected from the medical records of 178 clinical cases. Blood isolates were retrieved and ciprofloxacin MICs were measured. Forty-two cases in which ciprofloxacin was initiated within 24 h of the positive blood culture were used in the pharmacodynamic analysis. Significant factors with regard to treatment failure were low ciprofloxacin AUC(24)/MIC (P AUC(24) (P = 0.01). AUC(24)/MIC (P = 0.012) and MIC (P = 0.019) were significant variables in multivariate analyses; however, only the former remained significant (P = 0.038) after excluding two cases with ciprofloxacin-resistant isolates. An AUC(24)/MIC breakpoint of 250 was most significant, with cure rates of 91.4% (32/35) and 28.6% (2/7) in patients with values above and below this threshold, respectively (P = 0.001). The risk of ciprofloxacin treatment failure was 27.8 times (95% confidence interval, 2.1-333) greater in those not achieving an AUC(24)/MIC >or=250 (P = 0.011). Monte Carlo simulation of 5000 study subjects predicted that 0.88 of the population would achieve an AUC(24)/MIC >or=250 with standard-dose ciprofloxacin (400 mg intravenously every 12 h). This study confirms the pharmacodynamic parameters of ciprofloxacin that are important for optimizing the treatment of serious infections, particularly the benefits of achieving an AUC(24)/MIC >or=250, rather than the conventional target of >or=125. It also shows the relevance of dose selection in optimizing target attainment, with important differences among pathogens, even those with MICs within the susceptible range.

To evaluate dose-escalation of etelcalcetide (ONO-5163/AMG 416), a novel, intravenous (IV), long-acting calcium-sensing receptor agonist, for treatment of secondary hyperparathyroidism (SHPT) in Japanese hemodialysis patients. In this multicenter study, IV injections of etelcalcetide (3 times a week for 12 weeks) were administered, with dose escalation every 4 weeks depending on changes in serum intact parathyroid hormone (iPTH) and corrected calcium (cCa). A total of 24 patients participated in this study. Serum iPTH was reduced in a time- and dose-dependent manner, with reductions (in pg/mL) at 12 weeks of -226.1 ± 125.3, -362.5 ± 161.5, and -412.4 ± 130.2, respectively, for maximum doses of 5, 10, and 15 mg. At the end of the treatment, 50% of patients had serum iPTH levels within the target range (60 - 240 pg/mL). Serum cCa and phosphorus were reduced in parallel with iPTH. Adverse events (AEs) occurred in 20 patients (83.3%). The most frequently observed AEs (> 10%) were either mild or moderate nasopharyngitis (29.2%), decreased serum calcium (16.7%), and vomiting (12.5%). Dose-escalated triweekly etelcalcetide was effective for SHPT in Japanese hemodialysis patients and was satisfactorily tolerated.

Purpose: A prospective phase II trial was conducted to determine the efficacy and rate of organ preservation of alternate week concomitant chemoradiotherapy in stage II and III head and neck cancer. Methods: Forty-nine patients (10 stage II and 39 stage III) with squamous cell carcinoma of the head and neck region have been entered into a prospective phase II trial. Pretreatment evaluation included history and physical examination, computed tomography of the neck, bone scan, chest x-ray, panendoscopy and biopsy confirmation of malignancy. Therapy is given in 2 week cycles consisting of 5 days of concomitant chemoradiotherapy followed by a nine day break during which no treatment is given. Each cycle of treatment consists of 1.0 gm hydroxyurea P.O. every 12 hours for 6 days (11 doses per cycle) and 800mg/m 2 /d continuous infusion 5-fluorouracil along with concomitant radiation therapy (RT) administered in 1.8-2.0 Gy daily fractions for five days. This alternate week (week on/week off) schedule is continued for a total of 7 cycles resulting in an overall treatment time of 13 weeks and a total RT dose of 70 Gy. Extent of initial surgery included biopsy only (59.2%), minimal laser debulking (12.2%), and resection with or without neck dissection (28.6%). Results: The majority of patients are male (71.4%), with a median age of 61.3 years. Primary sites included oral cavity (16.3%), oropharynx (12.2%), larynx (57.1%), hypopharynx (8.1%), and nasopharynx (4.1%). T stage included T3 (32 patients, 65.3%), T2 (16 patients, 32.7%), and T1 (1 patient). N stage included N1 (17 patients, 34.7%), and N0 (32 patients, 65.3%). With a median follow-up of 27 months, the overall response rate is 100% (91.7 complete response, and 8.3% partial response). The 5 year actuarial local control, disease free survival, and overall survival is 90.1%, 88.3%, and 65.0%, respectively. One patient has failed with distant disease alone. Four patients had isolated local failures and (3(4)) were

To assess the safety, tolerability, biologic activity, and efficacy of belimumab in combination with standard of care therapy (SOC) in patients with active systemic lupus erythematosus (SLE). Patients with a Safety of Estrogens in Lupus Erythematosus: National Assessment (SELENA) version of the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score >/=4 (n = 449) were randomly assigned to belimumab (1, 4, or 10 mg/kg) or placebo in a 52-week study. Coprimary end points were the percent change in the SELENA-SLEDAI score at week 24 and the time to first SLE flare. Significant differences between the treatment and placebo groups were not attained for either primary end point, and no dose response was observed. Reductions in SELENA-SLEDAI scores from baseline were 19.5% in the combined belimumab group versus 17.2% in the placebo group. The median time to first SLE flare was 67 days in the combined belimumab group versus 83 days in the placebo group. However, the median time to first SLE flare during weeks 24-52 was significantly longer with belimumab treatment (154 versus 108 days; P = 0.0361). In the subgroup (71.5%) of serologically active patients (antinuclear antibody titer >/=1:80 and/or anti-double-stranded DNA [anti-dsDNA] >/=30 IU/ml), belimumab treatment resulted in significantly better responses at week 52 than placebo for SELENA-SLEDAI score (-28.8% versus -14.2%; P = 0.0435), physician's global assessment (-32.7% versus -10.7%; P = 0.0011), and Short Form 36 physical component score (+3.0 versus +1.2 points; P = 0.0410). Treatment with belimumab resulted in a 63-71% reduction of naive, activated, and plasmacytoid CD20+ B cells, and a 29.4% reduction in anti-dsDNA titers (P = 0.0017) by week 52. The rates of adverse events and serious adverse events were similar in the belimumab and placebo groups. Belimumab was biologically active and well tolerated. The effect of belimumab on the reduction of SLE disease activity or flares was not significant

1. Faecal samples from 19 commercial, 65 week old free-range egg laying flocks were examined to assess the prevalence and number of parasitic nematode eggs. Data were collected to characterise the housing, husbandry, behaviour and welfare of the flocks to examine possible relationships with the egg counts. 2. Eggs of at least one genus of nematode were present in the faeces of all 19 flocks. Heterakis eggs were detected in 17 (89%) flocks, Ascaridia in 16 (84%), Trichostrongylus in 9 (47%), and Syngamus in 6 (32%). Faecal egg counts (FEC) were greatest for Ascaridia and Heterakis. 3. For each nematode genus, there was no significant difference in FEC between organic (N = 9) and non-organic (N = 10) flocks, or between static (N = 8) and mobile (N = 11) flocks. 4. FEC were correlated with a range of housing, husbandry and management practices which varied between the nematode genus and included depth of the litter, percentage of hens using the range, and number of dead hens. Statistical analysis indicated relationships with FEC that included light intensity above the feeder, indoor and outdoor stocking density, fearfulness in the shed and on the range, distance to the nearest shelter, and swollen toes. 5. None of the FEC for any of the genera was correlated with weekly egg production or cumulative mortality. 6. Although nematode FEC were highly prevalent among the flocks, the overall lack of relation to other welfare and production measures suggests that these infections were not severe.

AIM: To assess the significance of interleukin (IL)-24 and vascular endothelial growth factor (VEGF) expression in lymph-node-positive rectal cancer. METHODS: Between 1998 and 2005, 90 rectal adenocarcinoma patients with lymph node involvement were enrolled. All patients received radical surgery and postoperative pelvic chemoradiotherapy of 50.4-54.0 Gy. Chemotherapy of 5-fluorouracil and leucovorin or levamisole was given intravenously during the first and last week of radiotherapy, and then monthly for about 6 mo. Expression of IL-24 and VEGF was evaluated by immunohistochemical staining of surgical specimens, and their relations with patient characteristics and survival were analyzed. The median follow-up of surviving patients was 73 mo (range: 52-122 mo). RESULTS: IL-24 expression was found in 81 out of 90 patients; 31 showed weak intensity and 50 showed strong intensity. VEGF expression was found in 64 out of 90 patients. Negative and weak intensities of IL-24 expression were classified as negative expression for analysis. IL-24 expression was significantly reduced in poorly differentiated tumors in comparison with well or moderately differentiated tumors (P = 0.004), N2b to earlier N stages (P = 0.016), and stage IIIc to stage IIIa or IIIb (P = 0.028). The number of involved lymph nodes was also significantly reduced in IL-24-positive patients in comparison with IL-24-negative ones.There was no correlation between VEGF expression and patient characteristics. Expression of IL-24 and VEGF was not correlated with survival, but N stage and stages were significantly correlated with survival. CONCLUSION: IL-24 expression was significantly correlated with histological differentiation, and inversely correlated with the degree of lymph node involvement in stage III rectal cancer.

Fifty-one elderly women (66.1±4.4 years, apparently healthy, insufficiently active, and without prior experience in RT were randomly assigned into two groups: Training Group (TG = 24 and Control Group (CG = 27. The TG was submitted to a standardized RT program composed of eight exercises, performed in two sets of 10 to 15 repetitions, three times a week, and the CG was submitted to a 12 week stretching exercise program composed by two sessions per week of 30 minutes each. Their physical and functional fitness level was analyzed before and after the intervention period by motor testing to assess Right and Left Upper Limb Endurance (RULE, LULE, Lower Limb Endurance (LLE, Flexibility (FLEX, Manual Skills (MS, Ability to Put on Socks (APS, and Coordination (COORD. The TG had improved performance in LLE (+13.8%, RULE (+24.3%, LULE (+22.9%, and MS (- 0.9 s, whereas the CG improved performance in RULE (+13.9% and LULE (+14.1%, but had increased time in COORD by (+1.5 s, and these were the only tests showing significant interactions of group vs. time (p<0.05. The results suggest that 12 weeks of RT seem to be sufficient to induce positive changes on physical and functional fitness of healthy and previously untrained elderly women.

Full Text Available Mild hypoxia is common after stroke and associated with poor long-term outcome. Oxygen supplementation could prevent hypoxia and improve recovery. A previous study of routine oxygen supplementation showed no significant benefit at 7 and 12 months. This pilot study reports the effects of routine oxygen supplementation for 72 hours on oxygen saturation and neurological outcomes at 1 week after a stroke.Patients with a clinical diagnosis of acute stroke were recruited within 24 h of hospital admission between October 2004 and April 2008. Participants were randomized to oxygen via nasal cannulae (72 h or control (room air, oxygen given only if clinically indicated. Clinical outcomes were assessed by research team members at 1 week. Baseline data for oxygen (n = 148 and control (n = 141 did not differ between groups.The median (interquartile range National Institutes of Health Stroke Scale (NIHSS score for the groups at baseline was 6 (7 and 5 (7 respectively. The median Nocturnal Oxygen Saturation during treatment was 1.4% (0.3 higher in the oxygen than in the control group (p<0.001 during the intervention. At 1 week, the median NIHSS score had reduced by 2 (3 in the oxygen and by 1 (2 in the control group. 31% of participants in the oxygen group and 14% in the control group had an improvement of ≥4 NIHSS points at 1 week doubling the odds of improvement in the oxygen group (OR: 2.9.Our data show that routine oxygen supplementation started within 24 hours of hospital admission with acute stroke led to a small, but statistically significant, improvement in neurological recovery at 1 week. However, the difference in NIHSS improvement may be due to baseline imbalance in stroke severity between the two groups and needs to be confirmed in a larger study and linked to longer-term clinical outcome.Controlled-Trials.com ISRCTN12362720; European Clinical Trials Database 2004-001866-41.

Household Consumption and Expenditures Surveys (HCES) are potential sources of data on dietary patterns for planning fortification programs, but they rarely have been compared with individual-level dietary assessment methods. To compare apparent consumption of fortifiable foods estimated from the Third Cameroon Household Survey (ECAM3) with the results of a national dietary survey using food frequency questionnaire (FFQ) and 24-hour recall (24HR) methods among women aged 15 to 49 years and children aged 12 to 59 months. We estimated coverage and frequency of consumption in the previous week (ECAM3 and FFQ) and coverage and amount consumed on the previous day (ECAM3 and 24HR) of refined vegetable oil, wheat flour, sugar, and bouillon cubes. Coverage in the past week as measured by the ECAM3 and FFQ, respectively, was 64% vs. 54% for oil, 60% vs. 92% for flour, 69% vs. 78% for sugar, and 85% vs. 96% for bouillon cubes. The different methods identified similar patterns of coverage among subgroups for oil, but patterns for other foods were variable. Frequency of consumption and previous-day coverage were lower with the ECAM3 than with the FFQ and 24HR, likely reflecting infrequent acquisition relative to intake. For women, the mean amounts consumed on the previous day (among consumers) were 43 vs. 29 g of oil, 71 vs. 83 g of flour, 42 vs. 32 g of sugar, and 5.0 vs. 2.4 g of bouillon cubes (ECAM and 24HR, respectively). HCES provide useful information on patterns of food access but inadequate information on individual consumption amounts to estimate appropriate food fortification levels. © The Author(s) 2015.

Weight gain secondary to antipsychotic medication is associated with many serious conditions, including type II diabetes mellitus, hypertension, and coronary heart disease, and also with poor medication compliance. Weight control programs may be of benefit to outpatients with schizophrenia, but also raise an issue of cost-effectiveness. We aimed to evaluate the effectiveness of a 10-week weight control program for outpatients taking atypical antipsychotics for treatment of schizophrenia, and to follow up the effects of this weight control program in controlling weight gain after termination of the program. A total of 33 patients with schizophrenia and antipsychotic-related obesity were enrolled in a 10-week multimodal weight control program. The patients' weights were recorded at baseline, week 4, week 8, week 10 (end of the intervention), week 12, week 24, and week 48. Secondary measures included blood sugar levels, cholesterol levels, triglyceride levels, quality of life and mental health. For those who completed the weight control program, there was a mean weight loss of 2.1 kg by the end of the intervention, 3.7 kg over 6 months, and 2.7 kg over 12 months. The mean body mass index decreased by 0.8, 1.5 and 1.1 at week 10, week 24 and week 48, respectively, all with statistical significance. The 10-week weight control program was effective in terms of weight reduction among obese patients with schizophrenia or schizoaffective disorder, and the weight reduction effect lasted for up to 6 months, and up to 12 months in some cases.

To compare the efficacy of an oscillating-rotating power toothbrush with a novel brush head incorporating angled CrissCross bristles (Oral-B Triumph with SmartGuide with Oral-B CrossAction brush head) versus a sonic toothbrush (Sonicare DiamondClean) for plaque and gingivitis reduction over a six-week period. This was a single-center, randomized, examiner-blind, two-treatment, parallel group study involving 65 subjects per group. Subjects presenting with mild-to-moderate gingivitis at Baseline were randomly assigned to either the oscillating-rotating brush or the sonic brush. They were instructed to use their assigned toothbrush and a standard fluoride dentifrice for two minutes twice daily at home for six weeks. Gingivitis and plaque were assessed at Baseline and Week 6 using the Modified Gingival Index (MGI), Gingival Bleeding Index (GBI), and Rustogi Modified Navy Plaque Index (RMNPI). Data were analyzed using an Analysis of Covariance (ANCOVA), with baseline as the covariate. Subjects also completed a consumer perception questionnaire to evaluate their brushing experience. One-hundred and thirty subjects were enrolled in the study and randomized to treatment. Sixty-four subjects per group completed the trial. Both brushes produced statistically significant reductions in gingivitis and plaque measures at Week 6 relative to Baseline (p gingivitis and plaque measures compared to the sonic toothbrush. The benefits for the oscillating-rotating brush over the sonic brush were 32.6% for gingivitis, 35.4% for gingival bleeding, 32% for number of bleeding sites, 22% for whole mouth plaque, 24.2% for gingival margin plaque, and 33.3% for approximal plaque (p gingival margin plaque, where p = 0.018). Analysis of the consumer perception questionnaire results showed subjects using the oscillating-rotating brush rated it higher for overall use experience and key attributes related to cleaning, gentleness, and brush head shape/size versus subjects in the sonic brush group

Full Text Available Pregnancy after the 40th week of gestation is often a great dilemma for obstetrician in diagnostic, therapeutic and in psychological terms as well. The aim of this study was to confirm the phenomenon of placental insufficiency in pregnancy after the 40th gestation week, the modality of delivery and perinatal outcome.The study comprised 3405 deliveries in a period of one year, 391 of which were terminated after the end of the 40th gestation week, including healthy pregnant women with singleton pregnancies. Control group included healthy pregnant women delivered between the 37th and 40th gestation week.The incidence of deliveries after the 40th week of gestation is 11.48%. Non-stress test was reactive in 99.65% of women in the study group. At the same time, CST (constriction– stress test was assessed as negative in 78.67% of cases. The pathological CST was found in only 1.33% of cases. Doppler ultrasound measurements showed the increased resistance in umbilical artery flow in 3% of cases. Vacuum extraction was used for 16.62%of deliveries in the study group, and 8.73% of deliveries in the control group (χ2=23.24;p<0.001. In the study group, Caesarean section was performed in 14.58% of cases, and in control group in 9.07% (χ2=11.09; p<0.001.Placental insufficiency induced by duration of pregnancy is a rear phenomenon in uncompromised pregnancy. There was no significant difference in the morbidity and mortality rates between the study and control group.

Objectives The aims of this study were to (i) investigate the association between night work or long work weeks and the risk of accidental injuries and (ii) test if the association is affected by age, sex or socioeconomic status. Methods The study population was drawn from the Danish version of the European Labour Force Survey from 1999-2013. The current study was based on 150 438 participants (53% men and 47% women). Data on accidental injuries were obtained at individual level from national health registers. We included all 20-59-year-old employees working ≥32 hours a week at the time of the interview. We used Poisson regression to estimate the relative rates (RR) of accidental injuries as a function of night work or long work weeks (>40 hours per week) adjusted for year of interview, sex, age, socioeconomic status (SES), industry, and weekly working hours or night work. Age, sex and SES were included as two-way interactions. Results We observed 23 495 cases of accidental injuries based on 273 700 person years at risk. Exposure to night work was statistically significantly associated with accidental injuries (RR 1.11, 99% CI 1.06-1.17) compared to participants with no recent night work. No associations were found between long work weeks (>40 hours) and accidental injuries. Conclusion We found a modest increased risk of accidental injuries when reporting night work. No associations between long work weeks and risk of accidental injuries were observed. Age, sex and SES showed no trends when included as two-way interactions.

Two independent studies assessed the duration of immunity of an inactivated adjuvanted Mycoplasma hyopneumoniae vaccine against mycoplasmal pneumonia in seronegative (study A, n=52) and seropositive (study B, n=52) pigs. The pigs were allocated randomly to treatment and were then injected with a single dose of either the vaccine or a placebo at approximately 1 week of age. Twenty-five weeks after treatment administration, the pigs were challenged with a virulent strain (LI 36, Strain 232) of M. hyopneumoniae and the extent of lung lesions consistent with mycoplasmal pneumonia was assessed 4 weeks later. In study A, the geometric mean lung lesion score (expressed as least squares mean percentages of lung lesions) was significantly (P=0.0001) lower in vaccinated (0.3%, n=20) than in control pigs (5.9%, n=24) seronegative to M. hyopneumoniae at enrolment; similarly, in study B, the extent of lung lesions was significantly reduced (P=0.0385) in seropositive vaccinated pigs (2.0%, n=22) compared to controls (4.5%, n=26). At the end of the investigation period, 4 weeks after challenge, mean antibody sample-to-positive (S/P) ratios were significantly higher both in seronegative (P=0.0012) and seropositive (P=0.0001) vaccinated pigs (mean values=0.77 and 0.81, respectively) than in controls (mean values=0.51 and 0.38, respectively).

Lifestyle modifications are successfully employed to treat obese and overweight women with polycystic ovary syndrome (PCOS). The aims of the current pilot study were (i) to compare the efficacy on reproductive functions of a structured exercise training (SET) programme with a diet programme in obese PCOS patients and (ii) to study their clinical, hormonal and metabolic effects to elucidate potentially different mechanisms of action. Forty obese PCOS patients with anovulatory infertility underwent a SET programme (SET group, n = 20) and a hypocaloric hyperproteic diet (diet group, n = 20). Clinical, hormonal and metabolic data were assessed at baseline, and at 12- and 24-week follow-ups. Primary endpoint was cumulative pregnancy rate. The two groups had similar demographic, anthropometric and biochemical parameters. After intervention, a significant improvement in menstrual cycles and fertility was noted in both groups, with no differences between groups. The frequency of menses and the ovulation rate were significantly (P diet group but the increased cumulative pregnancy rate was not significant. Body weight, body mass index, waist circumference, insulin resistance indexes and serum levels of sex hormone-binding globulin, androstenedione and dehydroepiandrosterone sulphate changed significantly (P diet interventions improve fertility in obese PCOS patients with anovulatory infertility. We hypothesize that in both interventions an improvement in insulin sensitivity is the pivotal factor involved in the restoration of ovarian function but potentially acting through different mechanisms.

Eveline Campos Monteiro de Castro

2016-03-01

Full Text Available Abstract Objective: To evaluate factors associated with neonatal death within 24 hours after birth in very low birth weight preterm newborns. Methods: Prospective cohort of live births with gestational age of 230/7–316/7 weeks, birth weight of 500–1499g without malformations, in 19 public maternity hospitals in nine capitals in northeastern Brazil from July to December 2007. The 19 hospitals were assessed in relation to physical resources, equipment, human resources and aiming at quality in care initiatives. Hospital, maternal and neonatal characteristics, neonatal morbidity, neonatal procedures and interventions were compared between preterm newborns that died or survived up to 24 hours of life. The variables associated with death within 24 hours after birth were determined by logistic regression. Results: Of the 627 newborns enrolled in the study, 179 (29% died within 168 hours after birth, of which 59 (33% up to 24 hours and 97 (54% up to 48 hours after birth. The variables associated with death <24h were: weight <1000g (2.94; 1.32–6.53, 5th minute Apgar <7 (7.17; 3.46–14.88, male gender (2.99; 1.39–6.47. A better hospital structure was a protective factor for early neonatal death (odds ratio: 0.34; 95% confidence interval: 0.17–0.71. Conclusions: The high neonatal mortality on the first day of life in capital cities of Northeast Brazil is associated with biological variables such as weight and gender of the newborn, as well as low vitality at birth and a worse infrastructure of the hospital where the birth occurred.

2006-01-01

Purpose: This study evaluated the treatment results of external beam radiotherapy administered in six fractions per week and high-dose-rate (HDR) brachytherapy for the treatment of cervical cancer. Methods and Materials: From July 2000 to July 2003, 43 patients were enrolled in this study. The patients received 45 Gy from a 10-MV photon beam using four-field box or anterior-posterior beams. Parametrial regions and the pelvic side walls were boosted with up to 50.4 Gy using a midline block. The daily fraction dose was 1.8 Gy administered in six-weekly fractions, from Monday to Saturday. HDR brachytherapy was also delivered at doses of 24 Gy to point A in six fractions twice a week. The median follow-up time was 37 months (range, 9-60 months). Results: The median overall treatment time was 51 days for all patients (range, 44-62 days). Thirty-four patients (79.1%) achieved complete remission and 8 (18.6%) achieved partial remission after radiotherapy. Locoregional recurrence occurred in 5 patients (11.6%), and a distant metastasis was encountered in 6 patients (13.9%). The 3-year overall survival, locoregional, and distant metastasis-free survival rates were 74.7%, 87.8%, and 84.7%, respectively. Grade 2 and 3 late rectal complications were encountered in 3 (6.5%) and 1 (2.2%), respectively. There were no Grade 3 late bladder complications. Conclusions: Six fractions per week of external beam radiotherapy and HDR brachytherapy is an effective treatment for patients with a carcinoma of the uterine cervix and can be used as a possible alternative to concomitant chemoradiotherapy in elderly patients or in patients with co-morbidity

Laying hens housed in free-range systems have access to an outdoor range, and individual hens within a flock differ in their ranging behaviour. Whether there is a link between ranging and laying hen welfare remains unclear. We analysed the relationships between ranging by individual hens on a commercial free-range layer farm and behavioural, physiological and health measures of animal welfare. We hypothesised that hens that access the range more will be (1) less fearful in general and in response to novelty and humans, (2) have better health in terms of physical body condition and (3) have a reduced physiological stress response to behavioural tests of fear and health assessments than hens that use the range less. Using radio frequency identification tracking across two flocks, we recorded individual hens' frequency, duration and consistency of ranging. We also assessed how far hens ventured into the range based on three zones: 0 to 2.4, 2.4 to 11.4 or >11.4 m from the shed. We assessed hen welfare using a variety of measures including: tonic immobility, open field, novel object, human approach, and human avoidance (HAV) behavioural tests; stress-induced plasma corticosterone response and faecal glucocorticoid metabolites; live weight, comb colour, and beak, plumage, footpad, and keel bone condition. Range use was positively correlated with plasma corticosterone response, faecal glucocorticoid metabolites, and greater flight distance during HAV. Hens that used the range more, moved towards rather than away from the novel object more often than hens that ranged less. Distance ranged from the shed was significantly associated with comb colour and beak condition, in that hens with darker combs and more intact beaks ranged further. Overall the findings suggest that there is no strong link between outdoor range usage and laying hen welfare. Alternatively, it may be that hens that differed in their ranging behaviour showed few differences in measures of welfare because

Tg.rasH2 Mice and not CByB6F1 Mice Should Be Used for 28-Day Dose Range Finding Studies Prior to 26-Week Tg.rasH2 Carcinogenicity Studies.

Science.gov (United States)

Paranjpe, Madhav G; Belich, Jessica; Vidmar, Tom J; Elbekai, Reem H; McKeon, Marie; Brown, Caren

Our recent retrospective analysis of data, collected from 29 Tg.rasH2 mouse carcinogenicity studies, determined how successful the strategy of choosing the high dose for the 26-week studies was based on the estimated maximum tolerated dose (EMTD) derived from earlier 28-day dose range finding (DRF) studies conducted in CByB6F1 mice. Our analysis demonstrated that the high doses applied at EMTD in the 26-week Tg.rasH2 studies failed to detect carcinogenic effects. To investigate why the dose selection process failed in the 26-week carcinogenicity studies, the initial body weights, terminal body weights, body weight gains, food consumption, and mortality from the first 4 weeks of 26-week studies with Tg.rasH2 mice were compared with 28-day DRF studies conducted with CByB6F1 mice. Both the 26-week and the earlier respective 28-day studies were conducted with the exact same vehicle, test article, and similar dose levels. The analysis of our results further emphasizes that the EMTD and subsequent lower doses, determined on the basis of the 28-day studies in CByB6F1 mice, may not be an accurate strategy for selecting appropriate dose levels for the 26-week carcinogenicity studies in Tg.rasH2 mice. Based on the analysis presented in this article, we propose that the Tg.rasH2 mice and not the CByB6F1 mice should be used in future DRF studies. The Tg.rasH2 mice demonstrate more toxicity than the CByB6F1 mice, possibly because of their smaller size compared to CByB6F1 mice. Also, the Tg.rasH2 males appear to be more sensitive than the female Tg.rasH2 mice.

To evaluate the role of transabdominal amnioinfusion in improving the perinatal outcomes of pregnancies complicated by preterm premature rupture of membranes (pPROM). A randomised controlled trial. A teaching hospital in Italy, obstetric unit. Population Women with singleton pregnancies complicated by pPROM, between 24 + 0 and 32 + 6 weeks of gestation. Patients were randomised 24 hours after admission to our referral hospital, to expectant management with transabdominal amnioinfusion or expectant management only. The effects of transabdominal amnioinfusion on pPROM-delivery interval and on perinatal outcomes. Of the 65 women with pPROM 34 met the inclusion criteria. Seventeen women were assigned to amnioinfusion (the amnioinfusion group) and the other 17 to expectant management. Compared with the control group (median: 8 days; range: 3-14), the pPROM-delivery period was significantly longer in women who underwent amnioinfusion (median: 21 days; range: 15-29) (P amnioinfusion were less likely to deliver within seven days since pPROM (RR: 0.18; range: 0.04-0.69 95% CI) or within two weeks (RR: 0.46; range: 0.21-1.02 95% CI). In the amnioinfusion group the neonatal survival was significantly higher at each gestational age (P amnioinfusion after pPROM resulted in significant prolongation of pregnancy and better neonatal outcomes.

Purpose Eggs are a food item of high nutritional value, a source of vitamin A and readily accessible to the general population. Methods This paper analysed the effect of cooking on the retinol levels of free-range and caged hen eggs, using high performance liquid chromatography (HPLC). The retinol levels of hen and quail eggs were also compared. Results The raw egg yolk retinol concentrations of free-range and caged hen eggs were 476.53+/-39.44 and 474.93+/-41.10 microg/100 g and cooked egg yolk concentrations were 393.53+/-24.74 and 379.01+/-30.78 microg/100 g, respectively; quail egg concentration was 636.56+/-32.71 microg retinol/100 g. No significant difference was found between the retinol of free-range and caged hen egg yolks; however, cooking diminished retinol levels, causing a loss of 17 and 20% in the free-range and caged hen egg yolks, respectively. Quail egg retinol concentration was significantly higher than that of the hens. Conclusion The retinol found in 100 g of hen and quail egg yolks could supply around 42 and 70.7% of the vitamin A requirements of an adult man, and is accordingly considered an excellent source of this vitamin.

The effects of multiple-modality exercise on arterial stiffening and cardiovascular fitness has not been fully explored. To explore the influence of a 24-week multiple-modality exercise program associated with a mind-motor training in cardiovascular health and fitness in community-dwelling older adults, compared to multiple-modality exercise (M2) alone. Participants (n=127, aged 67.5 [7.3] years, 71% females) were randomized to either M4 or M2 groups. Both groups received multiple-modality exercise intervention (60min/day, 3days/week for 24-weeks); however, the M4 group underwent additional 15min of mind-motor training, whereas the M2 group received 15min of balance training. Participants were assessed at 24-weeks and after a 28-week non-contact follow-up (52-weeks). at 52-weeks, the M4 group demonstrated a greater VO2max (ml/kg/min) compared to the M2 group (mean difference: 2.39, 95% CI: 0. 61 to 4.16, p=0.009). Within-group analysis indicated that the M4 group demonstrated a positive change in VO2max at 24-weeks (mean change: 1.93, 95% CI: 0.82 to 3.05, p=0.001) and 52-weeks (4.02, 95% CI: 2.71 to 5.32, p=0.001). Similarly, the M2 group increased VO2max at 24-weeks (2.28, 95% CI: 1.23 to 3.32, pMind-motor training associated with multiple-modality exercise can positively impact cardiovascular fitness to the same extent as multiple-modality exercise alone.

Preterm premature rupture of the membranes (PPROM) remains the leading cause of preterm deliveries and neonatal mortality and morbidity. The current cohort study sought to retrospectively examine perinatal outcomes in cases of PPROM < 34 weeks' gestation that were managed conservatively from 2010 to 2012 and to identify risk factors for short-term neonatal outcomes. Subjects were 510 pregnancies consisting of 114 twin and 396 singleton pregnancies. Clinical chorioamnionitis occurred in 17.8% of the pregnancies. Neonatal mortality was 7.4%, the rate of major neonatal conditions was 40%, and the rate of NICU admission was 72.9%. The latency period exceeded 48 h in 62.5% of the pregnancies and 7 days in 24.3% of the pregnancies. Twin pregnancies had a shorter latency period than singleton pregnancies (median of 2 days versus 4 days, p < 0.001). Pregnancies complicated with early vaginal bleeding had a higher neonatal mortality (13.95% vs. 6.36%, p = 0.013) and morbidity (51.16% vs. 38.32%, p = 0.024), fewer weeks of gestation at PPROM (p = 0.029). Multivariate logistic regression analysis revealed that weeks of gestation at PPROM (OR: 0.953, 95% CI: 0.939-0.966, p < 0.001) and a latency period (OR: 0.948, 95%CI: 0.926-0.970, p < 0.001) were associated with neonatal mortality or morbidity. A twin pregnancy (OR: 0.319, 95% CI: 0.17-0.6, p < 0.001) and weeks of gestation at PPROM (OR: 0.737, 95% CI: 0.66-0.822, p < 0.001) were associated with the latency period. Gestational age at PPROM, a twin pregnancy, and the latency period are associated with neonatal mortality and morbidity.

Previous studies have indicated that high sensation seekers are more sensitive to the reinforcing effects of nicotine, initiate smoking at an earlier age, and smoke greater amounts of cigarettes. This study examined the influence of sensation-seeking status on tobacco smoking following deprivation in regular tobacco users. Twenty healthy tobacco-smoking volunteers with low or high impulsive sensation-seeking subscale scores completed 2 consecutive test days per week for 3 consecutive weeks. Each week, a range of self-report, performance, and cardiovascular assessments were completed during ad libitum smoking on Day 1 and before and after the paced smoking of a tobacco cigarette containing 0.05, 0.6, or 0.9 mg of nicotine following 24 hr of tobacco deprivation on Day 2. In addition, self-administration behavior was analyzed during a 2-hr free access period after the initial tobacco administration. In high sensation seekers, tobacco smoking independent of nicotine yield ameliorated deprivation effects, whereas amelioration of deprivation effects was dependent on nicotine yield among low sensation seekers. However, this effect was limited to a small subset of measures. Subsequent cigarette self-administration increased in a nicotine-dependent manner for high sensation seekers only. Compared with low sensation seekers, high sensation seekers were more sensitive to the withdrawal relieving effects of nonnicotine components of smoking following 24 hr of deprivation on selective measures and more sensitive to nicotine yield during subsequent tobacco self-administration. These results are consistent with studies suggesting that factors driving tobacco dependence may vary as a function of sensation-seeking status.

Many new mothers return to work soon after childbirth. This study examines personal and work-related factors associated with the postpartum health of employed women 11 weeks after childbirth. Using a prospective cohort design, we recruited 817 Minnesota mothers into the study while they were hospitalized for childbirth in 2001. Telephone interviews were conducted at 5 and 11 weeks postpartum. Eligible women were 18 years or older, employed, and spoke English and gave birth to a singleton infant. Multivariate models using instrumental variables (2-stage least squares) were used to estimate personal and employment characteristics associated with women's physical and mental health and postpartum symptoms. At 11 weeks postpartum, 661 participants (81% of enrollees) completed a full interview, and 50% of participants had returned to work. On average, women reported 4.1 (SD 3.2) childbirth-related symptoms, most frequently fatigue (43%). Factors significantly associated with better health outcomes included better preconception health, the absence of prenatal mood problems, more control over work and home activities, more social support at work and home, and less job stress. The findings suggest postpartum women need to be evaluated regarding their fatigue levels and mental and physical symptoms. Women whose fatigue or postpartum symptoms limit daily role function may find it helpful to have health care clinicians counsel them on strategies to decrease job stress, increase social support at work and home, and certify their use of intermittent family and medical leave to help them manage their symptoms.

The behavior of plastic deformation in a duplex Cu-Zn alloy, in the temperature range 24-3000C

The mechanical behavior of Muntz Metal (Cu-40%Zn) containing duplex microstructure with a coarse grain size approximately 40μm) has been investigated at the temperature range 2 0 -300 0 C, and at strain rat e of epsilon=2.6x10 -4 S -1 , as a function of the second phase volume fraction(v(subβ)). Whereas at room temperature yielding increases with v(subβ) for v(subβ)>0.35, it remains virtually independent of v(subβ in the range 0.26 0 C. At low temperature (RT) and strains (epsilon approximately 0.01 the work hardening rate increases strongly with v subβ up to v subβ approximately 0.45. At higher temperatures and strains work hardening rate decreases for all volume fractions due to the thermal and dynamic recovery respectively. Then ultimate tensile strength (UTS) at room temperature increases with v subβ up to v subβ = 0.45, thus resulting in overall increase in U.T.S. The Portevin - Le Chatelier Effect (PLE)in Muntz Metal, at the temperature range 24 0 -300 0 C manifests itself in essentially two different forms. At RT, irregular serrations are observed, where amplitude decreases with increases in v subβ. At higher temperatures (100 0 C), serrations become regular, with increase in amplitude. At 200 0 C or over the serrations amplitude decrease at almost disappearing completely. These observations have been explained on the basis of collective behavior of mobile dislocations, influenced by the internal stress fields created during deformation by the presence of phase β. The Voce equation fits well with the experimental stress-strain data for temperatures up to 200 0 C. The method of Hollomon requires the use of stages in sigma-epsilon curve, curve, which does not have a physical significance. (Author) [pt

The present multicenter phase II study evaluated the efficacy and safety of weekly docetaxel as second-line chemotherapy for metastatic urothelial carcinoma. Weekly docetaxel was well tolerated but demonstrated modest activity, with a response rate of 6%, a median progression-free survival (PFS) of 1.4 months, and a median overall survival (OS) of 8.3 months. The dichotomy between PFS and OS was likely associated with subsequent platinum-based chemotherapy received by 58% of the patients. Docetaxel is commonly used for second-line therapy for metastatic urothelial carcinoma (UC). However, myelosuppression is a substantial concern when the traditional 3-week docetaxel cycle is used. The present multicenter phase II study evaluated the efficacy and safety of weekly docetaxel as second-line chemotherapy for metastatic UC. Patients with progression after previous platinum-based chemotherapy for advanced or metastatic disease were treated with docetaxel 30 mg/m(2) on days 1 and 8 every 21 days. The primary endpoint was the response rate. The study enrolled 31 patients. Their median age was 64 years (range, 40-79 years). An Eastern Cooperative Oncology Group performance status of 1, liver metastasis, and a hemoglobin level chemotherapy had been administered for metastatic disease in 29 patients (94%). Although fatigue (13%) and anorexia (6%) were the most frequently observed grade 3 to 4 toxicities, the safety profiles were generally mild and manageable. Two patients (6%) achieved an objective response, which was maintained for 3.0 to 7.8 months. Eight patients experienced disease stabilization (disease control rate, 32%). The median progression-free survival (PFS) and overall survival (OS) were 1.4 months (95% confidence interval [CI], 1.3-1.6) and 8.3 months (95% CI, 5.9-10.6), respectively. A relatively long OS was associated with further salvage platinum-based chemotherapy (n = 18, 58%) showing an encouraging activity (response rate, 44%; median PFS, 4.0 months

As a first application of the 32 Si tracer to a biomedical project, the first measurement of silicon uptake by a human subject has been carried out. The motivation for this study aroused from the supposition that silicate may be important in human physiology in protecting against aluminium toxicity. Indeed, in an earlier study of aluminium uptake, using the isotopic tracer, 26 Al, it had been shown that blood-Al levels following Al dosing were lower when the dose was accompanied by dissolved silicate than when it was not. An experiment was set out to determine directly the fraction absorbed from the gastrointestinal tract, and to quantify the kinetics of renal elimination, using the silicon isotopic tracer, 32 Si. A gas-filled magnet technique was developed for measuring 32 Si by AMS which allows a spatial separation of 32 S from 32 Si and hence a reduction in the counting rate entering the detector by a factor of 10 6 . The results for silicon absorption are consistent with those from earlier studies, indicating that the simultaneous ingestion of Al and silicate enhances the rate of aluminium excretion for a period of 12-24 hours

The objective of this study was to document pulse oximeter saturation levels achieved in the first 4 weeks of life in infants who were born at signal-extraction oximeters for a 72-hour period in each of the first 4 weeks of life. Data were compared with the pulse oximeter saturation target range prescribed by local institutional policy. Factors that were associated with intended range compliance were identified with hierarchical modeling. Fourteen centers from 3 countries enrolled 84 infants with mean +/- SD birth weight of 863 +/- 208 g and gestational age of 26 +/- 1.4 weeks. Oxygen saturation policy limits ranged between 83% and 92% for lower limits and 92% and 98% for upper limits. For infants who received respiratory support, median pulse oximeter saturation level achieved was 95%. Center-specific medial levels were within the intended range at 12 centers. Centers maintained infants within their intended range 16% to 64% of the time but were above range 20% to 73% of the time. In hierarchical modeling, wider target ranges, higher target range upper limits, presence of a policy of setting oximeter alarms close to the target range limits, and lower gestational age were associated with improved target range compliance. Success with maintaining the intended pulse oximeter saturation range varied substantially among centers, among patients within centers, and for individual patients over time. Most noncompliance was above the intended range. Methods for improving compliance and the effect of improved compliance on neonatal outcomes require additional research.

To examine the effects of 16 weeks of intensive cycling training on seminal reactive oxygen species (ROS), malondialdehyde (MDA), superoxide dismutase (SOD), catalase, and total antioxidant capacity (TAC) in male road cyclists. Repeated measures design. The Exercise Physiology Laboratory of the Urmia University. Twenty-four healthy nonprofessional male road cyclists (aged 17-26 years) participated in this study. All subjects participated in 16 weeks of intensive cycling training. The semen samples were collected, respectively, at baseline (T1), immediately (T2), 12 (T3), and 24 (T4) hours after the last training session in week 8; immediately (T5), 12 (T6), and 24 (T7) hours after the last training session in week 16; and 7 (T8) and 30 (T9) days after the last training session in week 16. Total antioxidant capacity and SOD were measured by colorimetric assay. The levels of ROS were measured by a chemiluminescence assay. Malondialdehyde levels were measured by thiobarbituric acid reactive substance assay. Catalase was measured by monitoring the initial rate of disappearance of hydrogen peroxide (initial concentration 10 mM) at 240 nm. The levels of seminal ROS and MDA increased (P < 0.008) and remained high after 30 days of recovery. The levels of seminal SOD, catalase, and TAC decreased (P < 0.008) and remained low after 30 days of recovery (P < 0.008). Sixteen weeks of intensive cycling training may have deleterious consequences for spermatozoa and hence may affect sperm healthy parameters in male cyclists.

Cloud-radiation representation in models for subgrid-scale clouds is a known gap from subseasonal-to-seasonal models down to storm-scale models applied for forecast duration of only a few hours. NOAA/ESRL has been applying common physical parameterizations for scale-aware deep/shallow convection and boundary-layer mixing over this wide range of time and spatial scales, with some progress to be reported in this presentation. The Grell-Freitas scheme (2014, Atmos. Chem. Phys.) and MYNN boundary-layer EDMF scheme (Olson / Benjamin et al. 2016 Mon. Wea. Rev.) have been applied and tested extensively for the NOAA hourly updated 3-km High-Resolution Rapid Refresh (HRRR) and 13-km Rapid Refresh (RAP) model/assimilation systems over the United States and North America, with targeting toward improvement to boundary-layer evolution and cloud-radiation representation in all seasons. This representation is critical for both warm-season severe convective storm forecasting and for winter-storm prediction of snow and mixed precipitation. At the same time the Grell-Freitas scheme has been applied also as an option for subseasonal forecasting toward improved US week 3-4 prediction with the FIM-HYCOM coupled model (Green et al 2017, MWR). Cloud/radiation evaluation using CERES satellite-based estimates have been applied to both 12-h RAP (13km) and also during Weeks 1-4 from 32-day FIM-HYCOM (60km) forecasts. Initial results reveal that improved cloud representation is needed for both resolutions and now is guiding further refinement for cloud representation including with the Grell-Freitas scheme and with the updated MYNN-EDMF scheme (both now also in global testing as well as with the 3km HRRR and 13km RAP models).

To evaluate and compare the effectiveness in reducing plaque of a fluoride dentifrice containing baking soda and a non-baking soda fluoride dentifrice containing an antimicrobial (triclosan/copolymer) system after a single brushing and over a four-week period of daily brushing. A total of 207 subjects completed this randomized, blinded, parallel-group clinical study. Twenty-four hour plaque buildup was scored at baseline and after two and four weeks of twice-daily use of the products. Additionally, controlled single brushing with the assigned dentifrice, followed by post-brushing plaque assessment, was performed at the start (baseline visit) and end (Week-4 visit) of the study. Plaque was scored using the Turesky, et al. modification of Quigley-Hein Index at six sites per tooth, according to Soparkar's modification. Mean baseline whole mouth plaque scores for the baking soda and triclosan dentifrice groups were 2.90 +/- 0.40 and 2.90 +/- 0.39, respectively, and the difference was not statistically significant. Within-group analysis showed that both products significantly reduced the amount of plaque over the four-week period (p baking soda dentifrice exhibited significantly greater reduction in plaque scores (p baking soda dentifrice group (0.34 +/- 0.32) was 2.22-fold greater than that observed for the triclosan dentifrice group (0.15 +/- 0.24). Similarly, single brushing with the baking soda dentifrice showed a 1.88- to 2.08-fold greater pre- to post-brushing plaque difference as compared to the triclosan dentifrice at the baseline visit (mean plaque reduction: baking soda 0.54 +/- 0.26; triclosan 0.28 +/- 0.18; ratio 1.88X) and Week-4 visit (baking soda 0.47 +/- 0.21; triclosan 0.23 +/- 0.15; ratio 2.08X). Similar to the whole mouth scores, evaluation of various tooth sites (facial, lingual, proximal, and gingival) showed a significantly greater reduction in plaque scores for brushing with the baking soda dentifrice as compared to brushing with the triclosan

Atomoxetine is a well-established pharmacotherapy for adult ADHD. Long-term studies show incremental reductions in symptoms over time. However, clinical experience suggests that patients differ in their response patterns. From 13 Eli Lilly-sponsored studies, we pooled and analyzed data for adults with ADHD who completed atomoxetine treatment at long-term (24 weeks; n=1443) and/or short-term (12 weeks; n=2830) time-points, and had CAARS-Inv:SV total and CGI-S data up to or after these time-points and at Week 0 (i.e. at baseline, when patients first received atomoxetine). The goal was to identify and describe distinct trajectories of response to atomoxetine using hierarchical clustering methods and linear mixed modelling. Based on the homogeneity of changes in CAARS-Inv:SV total scores, 5 response clusters were identified for patients who completed long-term (24 weeks) treatment with atomoxetine, and 4 clusters were identified for patients who completed short-term (12 weeks) treatment. Four of the 5 long-term clusters (comprising 95% of completer patients) showed positive trajectories: 2 faster responding clusters (L1 and L2), and 2 more gradually responding clusters (L3 and L4). Responses (i.e.≥30% reduction in CAARS-Inv:SV total score, and CGI-S score≤3) were observed at 8 and 24 weeks in 80% and 95% of completers in Cluster L1, versus 5% and 48% in Cluster L4. While many adults with ADHD responded relatively rapidly to atomoxetine, others responded more gradually without a clear plateau at 24 weeks. Longer-term treatment may be associated with greater numbers of responders. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

Objective: To investigate the effects of intratumoral implantation of 32 P -CP-PLLA seeds on the normal canine liver tissue and to explore the metabolism of 32 P-CP-PLLA seeds implanted in the liver of experimental dogs. Methods: Twelve beagles were enrolled in this study. The dogs were randomly and equally divided into four groups: group A (185 MBq), group B (370 MBq), group C (740 MBq) and group D (0 MBq). By using laparotomy procedure 32 P-CP-PLLA seeds were implanted into dog's liver. CT scan was performed before operation as well as before the dog was sacrificed. All dogs were sacrificed three months after the implantation. Before the procedure and 1, 2, 4, 8 and 12 weeks after the procedure the blood tests and serum biochemical tests were conducted. One dog from group B and group C was selected respectively and was fed in a metabolic cage. Within one month after the procedure the cpm in feces and in urine was determined every 24 hours. One dog was picked out from each of the three groups and was punctured to get its liver tissue for pathologic exam each time at 1, 2, 4, 8 and 12 weeks after the implantation, and SPECT imaging was also performed at the same time. Pathologic study, both macroscopic and microscopic (including optical and electronic microscopy) was made to observe the liver damage after the dog was sacrificed. The statistical analysis was processed by using SPSS 13.0 software and the measuring data were expressed with mean ± standard deviation (x ± s). Results: Two months after the procedure, serological examination found that the serum alkaline phosphatase (BKP) in both group B and group C was significantly higher than that in other groups, the difference was statistically significant (P 32 P-CP-PLLA seeds was manifested as a spherical lesion which was encysted by a layer of fibrous tissue with an edematous zone peripherally. Conclusion: The implantation of 32 P-CP-PLLA seeds in dog's liver causes only localized hepatic damage with no general

This study examined the effect of 12-week intensive dietary and exercise intervention program on body composition and stress-related hormones in obese women and to examine the residual effect after the intervention. The participants of this study were 30 obese women who had a body mass index of over 25 kg/m 2 and over 30% in body fat. They were classified into 2 groups depending on the history of weight cycling (WC); the WC group (≥ ±5% of the original body weight) and the non-weight cycling (NWC) group. Both groups were subject to a nutritional intervention program every 2 weeks with a mandatory exercise intervention for 12 weeks. Thereafter, the nutrition/exercise interventions were ceased for 12 weeks, after which the participants' levels of the hormones relating to energy metabolism and stress, meal intakes, dietary habits, level of knowledge on sodium intake, frequency of sodium intake, and quality of life (QOL) were checked. The changes of body weight were 71.3 ± 5.5 kg (week 0) vs. 65.0 ± 6.6 kg (week 12) vs. 65.6 ± 7.1 kg (week 24) in WC group and 71.6 ± 8.6 kg (week 0) vs. 68.8 ± 9.7 kg (week 12) vs. 70.3 ± 9.4 kg (week 24) in the NWC group. The levels of hormones, meal intakes, and QOL scores were better in the WC group, as adherence to the nutritional intervention was higher. We suggest that that adherence to dietary habits heavily influences weight loss and maintenance in individuals who frequently attempt to lose weight and consequently go through a vicious cycle of weight recycling.

There are limited validated food frequency questionnaires (FFQs) for infants and toddlers, most of which were evaluated in Europe or Oceania, and the ones available for use in the United States have important limitations. Our aim was to assess the validity of an FFQ developed for infants and toddlers. A semi-quantitative FFQ was developed that included 52 food items, their sources, and portion sizes. The FFQ inquired about diets over the previous 7 days. Its validity was assessed in a cross-sectional study. Participants completed the FFQ, followed by a 24-hour recall on two occasions with 1 week between data collection. A total of 296 caregivers of infants and toddlers aged 0 to 24 months enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children, Puerto Rico. Intake of nutrients and food groups were averaged for the two FFQs and the two 24-hour food recalls, and adjusted for energy intake. Spearman correlations were performed for intakes of energy, nutrients, and foods between administrations and between instruments. Correlation coefficients were de-attenuated to account for variation in the 24-hour recalls. A total of 241 participants completed the study. Intake of all nutrients and foods were significantly correlated between FFQs and 24-hour recalls and between the means of FFQs and 24-hour food recalls. The de-attenuated correlation for nutrients between the FFQs and 24-hour recalls ranged from 0.26 (folate) to 0.77 (energy), with a mean correlation of 0.53. The de-attenuated correlation for food groups between the FFQs and 24-hour recalls ranged from 0.28 (sweets) to 0.80 (breast milk), with a mean correlation of 0.55. When analyses were restricted to those consuming foods other than breast milk or formula (n=186), results were similar. This semi-quantitative FFQ is a tool that offers reasonably valid rankings for intake of energy, nutrients, foods, and food groups in this sample of infants and toddlers. Copyright © 2017 Academy

OBJECTIVE: The chemokine receptor CCR5 may be important for the recruitment of pathogenic T cells to the CNS in multiple sclerosis (MS). We hypothesized that this chemokine receptor might still be important for T-cell migration during treatment with anti-very late antigen (VLA)-4 antibody. We...... impact on the frequency of relapses 1 year prior to natalizumab treatment or during the first 48 weeks of treatment. The multiple sclerosis severity score (MSSS) was significantly lower at baseline in patients carrying CCR5 Δ32 (P = 0.031). CONCLUSIONS: CCR5 Δ32 is not associated with lower disease...

Elderly patients have been often excluded from or underrepresented in the study populations of combination chemotherapy trials. The primary end point of this study was to determine the response rate and the toxicity of the weekly oxaliplatin, 5-fluorouracil and folinic acid (OXALF) regimen in elderly patients with advanced gastric cancer. The secondary objective was to measure the time to disease progression and the survival time. Chemotherapy-naive patients with advanced gastric cancer aged 70 or older were considered eligible for study entry. Patients received weekly oxaliplatin 40 mg/m2, fluorouracil 500 mg/m2 and folinic acid 250 mg/m2. All drugs were given intravenously on a day-1 schedule. A total of 42 elderly patients were enrolled. Median age was 73 years and all patients had metastatic disease. The response rate according to RECIST criteria was 45.2% (95% CIs: 30%–56%) with two complete responses, 17 partial responses, 13 stable diseases and 10 progressions, for an overall tumor rate control of 76.2% (32 patients). Toxicity was generally mild and only three patients discontinued treatment because of treatment related adverse events. The most common treatment-related grade 3/4 adverse events were fatigue (7.1%), diarrhoea (4.8%), mucositis (2.4%), neurotoxicity (2.4%) and neutropenia (4.8%). The median response duration was 5.3 months (95% CIs: 2.13 – 7.34), the median time to disease progression was 5.0 months (95% CIs: 3.75 – 6.25) and the median survival time was 9.0 months (95% CIs: 6.18 – 11.82).

Although microsurgery remains the first-line treatment, gross total resection of cystic craniopharyngeomas (CP) is associated with significant morbidity and mortality and the addition of external irradiation to subtotal resection proves to achieve similar tumor control. However, concern regarding long-term morbidity associated with external irradiation in children still remains. With this retrospective analysis, the authors emphasize intracavitary brachytherapy using phosphorus-32 (P-32) as a treatment option for children with cystic CP. Between 1992 and 2009, 17 children (median age 15.4 years; range 7-18 years) with cystic CP underwent intracavitary brachytherapy using P-32. Eleven patients were treated for recurrent tumor cysts; 6 patients were treated primarily. MR imaging revealed solitary cysts in 7 patients; 10 patients had mixed solid-cystic lesions (median tumor volume 11.1 ml; range 0.5-78.9 ml). The median follow-up time was 61.9 months (range 16.9-196.6 months). Local cyst control could be achieved in 14 patients (82 %). Three patients showed progression of the treated cystic formation (in-field progression) after a median time of 8.3 months (range 5.3-10.3 months), which led to subsequent interventions. The development of new, defined cysts and progression of solid tumor parts (out-of-field progression) occurred in 5 patients and led to additional interventions in 4 cases. There was neither surgery-related permanent morbidity nor mortality in this study. The overall progression-free survival was 75, 63, and 52 % after 1, 3, and 5 years, respectively. Intracavitary brachytherapy using P-32 represents a safe and effective treatment option for children harboring cystic CP, even as primary treatment. However, P-32 does not clearly affect growth of solid tumor parts or the development of new cystic formations. (orig.) [de

Is escitalopram really relevantly superior to citalopram in treatment of major depressive disorder? A meta-analysis of head-to-head randomized trials.

Trkulja, Vladimir

2010-02-01

To evaluate clinical relevance of differences between escitalopram and citalopram (equimolar) for major depressive disorder. Review and meta-analysis of comparative randomized controlled trials (RCT). Comparisons were in relation to Montgomery-Asberg depression rating scale (MADRS) score reduction at weeks 1 (5 RCTs), 4 (5 RCTs), 6 (4 RCTs), 8 (5 RCTs), and 24 (1 RCT); proportion of responders at weeks 2, 4, 6 (2 RCTs for each time point), 8 (5 RCTs), and 24 (1 RCT); clinical global impression-severity (CGI-S) reduction at weeks 6 (1 RCT), 8 (5 RCTs), and 24 (1 RCT), and discontinuation due to adverse events or inefficacy during short-term (up to 8 weeks) and medium-term (24 weeks) treatment. MADRS reduction was greater with escitalopram, but 95% confidence intervals (CI) around the mean difference were entirely or largely below 2 scale points (minimally important difference) and CI around the effect size (ES) was below 0.32 ("small") at all time points. Risk of response was higher with escitalopram at week 8 (relative risk, 1.14; 95% CI, 1.04 to 1.26) but number needed to treat was 14 (95% CI, 7 to 111). All 95% CIs around the mean difference and ES of CGI-S reduction at week 8 were below 0.32 points and the limit of "small," respectively. Data for severe patients (MADRS> or =30) are scarce (only 1 RCT), indicating somewhat greater efficacy (response rate and MADRS reduction at week 8, but not CGI-S reduction) of escitalopram, but without compelling evidence of clinically relevant differences. Discontinuations due to adverse events or inefficacy up to 8 weeks of treatment were comparable. Data for the period up to 24 weeks are scarce and inconclusive. Presently, the claims about clinically relevant superiority of escitalopram over citalopram in short-to-medium term treatment of major depressive disorder are not supported by evidence.

This research examined electronic cigarette (e-cigarette) use by individuals in treatment for substance abuse, a population with a high prevalence of tobacco use and poor smoking cessation outcomes. We surveyed 1127 individuals from 24 substance abuse treatment centers across the United States. Bivariate analyses and logistic regression were used to examine factors associated with daily (N = 87) versus weekly (N = 81) e-cigarette use. Among the full sample, 59.8% reported any lifetime use of e-cigarettes, with 23.6% reporting past 30-day use. Daily e-cigarette users were more likely to have used second-generation, tank-type e-cigarettes, χ2(1,N = 165) = 11.54, p = .001, used more flavors overall, t(168) = 2.15, p = .03, and were more likely to report using their e-cigarette continuously throughout the day, χ2(4,N = 168) = 16.7, p = .002, compared to weekly e-cigarette users. Over half (57.7%) of the daily and weekly e-cigarette users reported having an e-cigarette device that broke. The logistic regression model adjusting for clinic type and days with poor mental health found that daily e-cigarette users were significantly more likely than weekly e-cigarette users to be from methadone clinics (adjusted odds ratio [AOR] = 2.40, p = .04), and former smokers (AOR = 6.37, p users in substance abuse treatment were more likely to be from methadone clinics and former cigarette smokers. However, the majority (73.6%) of daily e-cigarette users were current cigarette smokers. E-cigarette device type reliability (eg, breakage) may be an important factor to consider among drug treatment and other populations with lower socioeconomic status. This study found several differences in the device type, flavors, and use characteristics of daily versus weekly e-cigarette users. While majority of e-cigarette users in substance abuse treatment were current cigarette smokers, daily e-cigarette users were more likely to be former cigarette smokers.

PURPOSE This trial was designed to evaluate the optimal dose of massage for individuals with chronic neck pain. METHODS We recruited 228 individuals with chronic nonspecific neck pain from an integrated health care system and the general population, and randomized them to 5 groups receiving various doses of massage (a 4-week course consisting of 30-minute visits 2 or 3 times weekly or 60-minute visits 1, 2, or 3 times weekly) or to a single control group (a 4-week period on a wait list). We assessed neck-related dysfunction with the Neck Disability Index (range, 0–50 points) and pain intensity with a numerical rating scale (range, 0–10 points) at baseline and 5 weeks. We used log-linear regression to assess the likelihood of clinically meaningful improvement in neck-related dysfunction (≥5 points on Neck Disability Index) or pain intensity (≥30% improvement) by treatment group. RESULTS After adjustment for baseline age, outcome measures, and imbalanced covariates, 30-minute treatments were not significantly better than the wait list control condition in terms of achieving a clinically meaningful improvement in neck dysfunction or pain, regardless of the frequency of treatments. In contrast, 60-minute treatments 2 and 3 times weekly significantly increased the likelihood of such improvement compared with the control condition in terms of both neck dysfunction (relative risk = 3.41 and 4.98, P = .04 and .005, respectively) and pain intensity (relative risk = 2.30 and 2.73; P = .007 and .001, respectively). CONCLUSIONS After 4 weeks of treatment, we found multiple 60-minute massages per week more effective than fewer or shorter sessions for individuals with chronic neck pain. Clinicians recommending massage and researchers studying this therapy should ensure that patients receive a likely effective dose of treatment. PMID:24615306

Counseling for patients with impending premature delivery traditionally has been based primarily on the projected gestational age at delivery. There are limited data regarding how the indications for the preterm birth affect the neonatal outcome and whether this issue should be taken into account in decisions regarding management and patient counseling. We performed a prospective study of pregnancies resulting in premature delivery at less than 32 weeks to determine the influence of both the indications for admission and their associated indications for delivery on neonatal mortality and complications of prematurity. This is a multicenter, prospective study in 10 hospitals where all data from the neonatal intensive care unit routinely was imported to a deidentified data warehouse. Maternal data were collected prospectively at or near the time of delivery. Eligible subjects included singleton deliveries in these hospitals between 23 0/7 and 31 6/7 weeks. The primary hypothesis of the study was to determine whether there was a difference in the primary outcome, which was defined as neonatal composite morbidity, between those neonates delivered after admission for premature labor vs premature rupture of membranes, because these were expected to be the 2 most frequent diagnoses leading to premature birth. The sample size was calculated based on a 10% difference in outcomes for these 2 entities. We based this hypothesis on the knowledge that premature rupture of membranes has a greater incidence of intra-amniotic infection and inflammation than premature labor and that outcomes for premature neonates are worse when delivery is associated with intra-amniotic infection. Additional outcomes were analyzed for all other indications for admission and delivery. Composite morbidity was defined as ≥1 of the following: respiratory distress syndrome (oxygen requirement, clinical diagnosis, and consistent chest radiograph), bronchopulmonary dysplasia (requirement for oxygen

Maxwellian-averaged cross sections of neutron capture, fission, (n,p) and (n,{alpha}) reactions are calculated from the Japanese Evaluated Nuclear Data Library, JENDL-3.2, for applications in the astrophysics. The calculation was made in the temperature (kT) range from 1 keV to 1 MeV. Results are listed in tables. The Maxwellian-averaged capture cross sections were compared with recommendations of other authors and recent experimental data. Large discrepancies were found among them especially in the light mass nuclides. Since JENDL-3.2 reproduces relatively well the recent experimental data, we conclude that JENDL-3.2 is superior to the others in such a mass region. (author)

We retrospectively investigated the efficacy and safety profile of weekly low-dose docetaxel (DTX) with estramustine in comparison with triweekly standard-dose DTX treatment for Japanese patients with castration-resistant prostate cancer (CRPC). Between April 2002 and January 2011, 75 CRPC patients were treated with triweekly DTX (60-75 mg/m(2) every 3 weeks) (standard-dose group), and 76 CRPC patients were treated with weekly low-dose DTX (20-30 mg/m(2) on days 2 and 9 with estramustine 560 mg on days 1-3 and 8-10) every 3 weeks (low-dose group). Prostate-specific antigen (PSA) response and progression-free and overall survival were analyzed in each group. Median serum PSA level of the standard-dose group and low-dose group was 25.0 and 35.5 ng/ml, respectively. In the standard-dose and low-dose groups, 57.8 and 65.2 % of patients, respectively, achieved a PSA decline ≥ 50 %. There was no significant difference in either median time to progression between the standard-dose group (10.0 months) and low-dose group (7.1 months) or in median duration of survival between the standard-dose group (24.2 months) and low-dose group (30.6 months). Multivariate analysis with a Cox proportional hazards regression model showed that DTX treatment protocol did not influence the risk of death. Incidences of grade 3-4 neutropenia, febrile neutropenia, and thrombocytopenia were significantly higher in the standard-dose versus low-dose group (58.7 vs. 7.9 %, 16.0 vs. 3.9 %, and 8.0 vs. 0 %, respectively). For Japanese CRPC patients, weekly low-dose DTX combined with estramustine has similar efficacy to standard-dose DTX but with fewer adverse events.

Eradication of micrometastases present in lymph nodes of cancer patients improves their prognosis significantly. Radionuclide therapy possesses the potential to eliminate such metastases. This study was performed to evaluate the efficacy and safety of 32 P-nanocolloid therapy in the treatment of distant carcinoma cell metastases in lymph nodes of VX2 tumor-bearing rabbits. The Method of this study was to obtain VX2 tumor micrometastases in right armpit lymph nodes of 12 male New Zealand white rabbits, VX2 tumors were implanted by hypodermal inoculation into the right anterior limb. Animals were randomly divided into therapy (n=6) and control (n=6) groups. 32 P-nanocolloid (0.5 mCi), 95% of which was >50 nm in diameter, was administered to the therapy group, and saline was administered to the control group. Injections were given once weekly for 4 weeks. 2-Deoxy-2[ 18 F]-fluoro-D-glucose positron emission tomography revealed that the number of involved lymph nodes and the maximum standardized uptake value decreased in the 32 P-nanocolloid therapy group as compared with the baseline or saline control group (P 32 P-nanocolloid. These findings support treatment with 32 P-nanocolloid as a safe and effective approach for eradication of lymph node micrometastases. (author)

Breastfeeding is recognised as the optimal method for feeding infants with health gains made by reducing infectious diseases in infancy; and chronic diseases, including obesity, in childhood, adolescence and adulthood. Despite this, exclusivity and duration in developed countries remains resistant to improvement. The objectives of this research were to test if an automated mobile phone text messaging intervention, delivering one text message a week, could increase "any" breastfeeding rates and improve breastfeeding self-efficacy and coping. Women were eligible to participate if they were: over eighteen years; had an infant less than three months old; were currently breastfeeding; no diagnosed mental illness; and used a mobile phone. Women in the intervention group received MumBubConnect, a text messaging service with automated responses delivered once a week for 8 weeks. Women in the comparison group received their usual care and were sampled two years after the intervention group. Data collection included online surveys at two time points, week zero and week nine, to measure breastfeeding exclusivity and duration, coping, emotions, accountability and self-efficacy. A range of statistical analyses were used to test for differences between groups. Hierarchical regression was used to investigate change in breastfeeding outcome, between groups, adjusting for co-variates. The intervention group had 120 participants at commencement and 114 at completion, the comparison group had 114 participants at commencement and 86 at completion. MumBubConnect had a positive impact on the primary outcome of breastfeeding behaviors with women receiving the intervention more likely to continue exclusive breastfeeding; with a 6% decrease in exclusive breastfeeding in the intervention group, compared to a 14% decrease in the comparison group (p issues.

To develop an immunoassay and further an immunosensor for 2,4-D based upon recombinant antibody, the Fab fragments of 2,4-D specific antibody were expressed in E. coli. Western blotting analysis of the periplasmic cell fractions shown that under the non-reducing condition only a single protein band at a molecular mass of 45-kDa, corresponding to the whole Fab fragment was detected. Antigen binding activity for 2,4-D was found only in the extract of cells bearing the 2,4-D plasmid. An immunoassay based on the competitive reaction of 2,4-D and enzyme tracer with 2,4-D Fab fragments immobilized on micro titer plates via rabbit anti-mouse IgC was developed. Using this assay, 2,4-D could be detected at concentration range of 0.5 (mu) g/1 to 10(mu) g/1. The center point of the 2,4-D test was found at a concentration of 5 (mu) g/l. The assay was applied for detection of 2,4-D in spiked orange samples, resulting in recovery rate of 90 percent. The immunoassay could be applied to monitor human exposure to 2,4-D from contamination in fruit samples.

Recovery duration may be too short during the congested fixtures of professional soccer players with regard to maintaining physical performance and a low injury rate. To analyze the effects of 2 matches per week on physical performance and injury rate in male elite soccer players. Cohort study; Level of evidence, 3. Match results, match-related physical performance, and injuries were monitored during 2 seasons (2007-2008 and 2008-2009) for 32 professional soccer players in a top-level team participating in the UEFA (Union of European Football Associations) Champions League. Total distance, high-intensity distance, sprint distance, and number of sprints were collected for 52 home matches. Injuries and player participation in matches and training were recorded throughout the full season. Physical performance, as characterized by total distance covered, high-intensity distance, sprint distance, and number of sprints, was not significantly affected by the number of matches per week (1 versus 2), whereas the injury rate was significantly higher when players played 2 matches per week versus 1 match per week (25.6 versus 4.1 injuries per 1000 hours of exposure; P physical performance tested but is not long enough to maintain a low injury rate. The present data highlight the need for player rotation and for improved recovery strategies to maintain a low injury rate among athletes during periods with congested match fixtures.

The accuracy of dielectronic recombination (DR) data for astrophysics related ions plays a key role in astrophysical plasma modeling. The absolute DR rate coefficient of Fe17+ ions was measured at the main cooler storage ring at the Institute of Modern Physics, Lanzhou, China. The experimental electron-ion collision energy range covers the first Rydberg series up to n = 24 for the DR resonances associated with the {}2P1/2\\to {}2P3/2{{Δ }}n=0 core excitations. A theoretical calculation was performed by using FAC code and compared with the measured DR rate coefficient. Overall reasonable agreement was found between the experimental results and calculations. Moreover, the plasma rate coefficient was deduced from the experimental DR rate coefficient and compared with the available results from the literature. At the low energy range, significant discrepancies were found, and the measured resonances challenge state-of-the-art theory at low collision energies.

Feed coals and fly ashes from a coal-fired power station burning Alberta subbituminous coal were examined for a period of thirty-eight weeks to determine the variation in emitted mercury. Feed coal samples were analyzed for proximate, calorific value and Hg content, while fly ash samples were examined for C and Hg contents. The maceral content of the feed coal was also determined. The emitted mercury was calculated and compared to mercury emitted from the stack according to a mass-balance calculation from a previous study for the same station. Mercury contents ranged from 0.029 to 0.066 mg/kg for feed coal, and from 0.069 to 0.112 mg/kg for fly ash. The carbon/char in fly ash was separated into reactive (vitrinitic/bimacerate) and less reactive (inertinitic) chars using ZnBr{sub 2} at specific gravities of 1.7, 2.0, and 2.25 to 2.4. The result shows that there is a positive correlation between the carbon and mercury content of the fly ash. The reactive char particles in the fly ash may be responsible for the capture mercury in fly ash. The percentage of estimated captured mercury by fly ash increases with increasing carbon content (%) in fly ash. The percentage of emitted mercury for the period of 38 weeks is estimated to be within the range of 49% to 76% of the total input of mercury. (author)

To assess safety, tolerability, and efficacy of the antigen-specific immunotherapy ATX-MS-1467 in participants with relapsing multiple sclerosis using different treatment protocols to induce tolerance. Two open-label trials in adult participants with relapsing multiple sclerosis were conducted. Study 1 was a multicenter, phase 1b safety evaluation comparing intradermal (i.d.) (cohort 1) with subcutaneous (cohort 2) administration in 43 participants. Both cohorts received ATX-MS-1467 dosed at 25, 50, 100, 400, and 800 μg at 14-day intervals over 8 weeks, followed by 8 weeks with 4 additional 800-μg doses at 14-day intervals and 32 weeks off study medication. Study 2 was a phase 2a, multicenter, single-arm trial enrolling 37 participants. ATX-MS-1467 was titrated from 50 μg i.d. on day 1 to 200 μg on day 15 and 800 μg on day 29 followed by biweekly administration of 800 μg for 16 weeks and 16 weeks off study medication. Efficacy was evaluated on MRI parameters and clinical variables. Safety endpoints included treatment-emergent adverse events and injection-site reactions. In study 1, there was a significant decrease in new/persisting T1 gadolinium-enhanced (GdE) lesions in cohort 1 from baseline to week 16, returning to baseline values at week 48. In study 2, the number of T1 GdE lesions were significantly reduced on treatment and remained reduced at study completion. Safety results were unremarkable in both studies. Relatively slow ATX-MS-1467 titration and a longer full-dose i.d. treatment period is associated with reduction in GdE lesions and a sustained effect post treatment. Further trials of ATX-MS-1467 are warranted. This work provides Class IV evidence that for patients with relapsing multiple sclerosis, slow ATX-MS-1467 titration and a longer full-dose i.d. treatment period is associated with reduction in GdE lesions. © 2018 American Academy of Neurology.

Full Text Available The polymorphism of locus BoLA-DRB3.2 of the Major Histocompatibility Complex was evaluated in two northern Mexican Creole cattle populations, Chihuahua (n = 47 and Tamaulipas (n = 51. The BoLA-DRB3.2 locus was typed by amplification and digestion with restriction endonuclease enzymes (PCR-RFLP. Fifty-two alleles were detected (28 previously reported and 24 new ones. In the Chihuahua population, 18 alleles and 5.5 effective alleles were found, while in the Tamaulipas population there were 34 and 10.8, respectively. The allele frequencies ranged from 0.011 to 0.383 in Chihuahua and from 0.010 to 0.206 in Tamaulipas. The frequencies of the new alleles in both cattle populations were low (0.010 to 0.053. The expected heterozygosity was 0.827 and 0.916, respectively, for the Chihuahua and Tamaulipas populations. Both populations presented a heterozygote deficit: [Chihuahua F IS = 0.1 (p = 0.019 and Tamaulipas F IS = 0.317 (p < 0.001]. In conclusion, this study showed that the Mexican Creole cattle have many low-frequency alleles, several of which are exclusive to these populations. Genetic distances obtained show that the Mexican Creole cattle population is composed of independent populations, far apart from other South American Creole populations.

To evaluate the efficacy/safety of belimumab in patients with rheumatoid arthritis (RA). Patients fulfilling American College of Rheumatology (ACR) criteria for RA for ≥ 1 year who had at least moderate disease activity while receiving stable disease-modifying antirheumatic drug (DMARD) therapy and failed ≥ 1 DMARD were randomly assigned to placebo or belimumab 1, 4, or 10 mg/kg, administered intravenously on Days 1, 14, and 28, and then every 4 weeks for 24 weeks (n = 283). This was followed by an optional 24-week extension (n = 237) in which all patients received belimumab. Primary efficacy endpoint was the Week 24 ACR20 response. Week 24 ACR20 responses with placebo and belimumab 1, 4, and 10 mg/kg were 15.9%, 34.7% (p = 0.010), 25.4% (p = 0.168), and 28.2% (p = 0.080), respectively. Patients taking any belimumab dose who continued with belimumab in the open-label extension had an ACR20 response of 41% at 48 weeks. A similar ACR20 response (42%) at 48 weeks was seen in patients taking placebo who switched in the extension to belimumab 10 mg/kg. Greater response rates were observed in patients who at baseline were rheumatoid factor-positive, anticitrullinated protein antibody-positive, or tumor necrosis factor inhibitor-naive, or had elevated C-reactive protein levels, Disease Activity Score 28 > 5.1, or low B lymphocyte stimulator levels (< 0.858 ng/ml). Adverse event rates were similar across treatment groups. In this phase II trial, belimumab demonstrated efficacy and was generally well tolerated in patients with RA who had failed previous therapies. [ClinicalTrials.gov identifier NCT00071812].

Full Text Available Premise of the study: Microsatellite primers were developed in the hemiparasitic perennial forb Castilleja sessiliflora to investigate patterns of gene flow and genetic diversity within and among populations. Methods and Results: Twelve polymorphic loci were identified in C. sessiliflora and tested on three populations (32 individuals each sampled across the range of the species. The loci amplified di- and trinucleotide repeats with 3–14 alleles per locus. To assess cross-amplification, primer pairs were also tested on 24 additional Castilleja species that represent the morphological and geographic diversity of the genus. We provide reports of their effectiveness in all 25 taxa. Conclusions: These results indicate the utility of these primers in C. sessiliflora for future studies of genetic structure and gene flow, as well as their widespread applicability in other members of the diverse and complex genus Castilleja.

The MED was 1mg/kg/day for neonates born at more than 32 GA (n = 24). Omeprazole is extensively prescribed on clinical symptoms but efficacy is not demonstrated while safety concerns do exist. When treatment is required, the daily dose needs to be validated in preterm and term neonates. Optimal doses of omeprazole to increase gastric pH and decrease reflux index below 5% over 24 hours, determined using an adaptive Bayesian design differ among neonates. Both gestational and postnatal ages account for these differences but their differential impact on omeprazole

[Purpose] This study prescribed pain-free range exercises for a female amateur skier who complained of limitations in her shoulder range of motion, and pain caused by protective spasms; the tester evaluated the effects of such exercise on pain. [Subject and Methods] A 23-year-old female who complained of pain of 3 weeks in duration in the right glenohumoral and scapulothoracic joints was enrolled. [Results] After pain-free range exercises, the visual analog pain score was 2 and the shoulder flexion and abduction angles improved compared to the initial values. [Conclusion] Thus, this study suggests muscle-strengthening exercises within the pain-free range, rather than simple pain treatments, as therapy for acute muscle injuries in skiers.

Objective: To evaluate the repeated bout effect in exercise sessions with different intervals after a week of the first session. Materials and Methods: 14 men (18 to 30 years engaged in strength training for a minimum of 6 months were divided into two groups A and B. The participants performed five sets, maximum repetitions with two minutes of rest between sets at 85% 1RM in biceps curl exercise unilateral Scott on the bench with the non-dominant arm. The second training session was performed 24 h later, for group A, and 48 hours later for group B. Blood samples were collected in pre measures, 24h, 48h, 72h and 96h, arm girth measurements, range of motion in flexion and extension, and measures of subjective perception of pain on palpation and by extension, before and after exercise every day of the tests. Results: When the first two exercise sessions were performed with shorter rest intervals (24 hours due to increased pain sensation, maintaining range of motion and reduced activity for longer serum CK higher. Conclusion: Exercises with short intervals (24 hours may modulate the repeated bout effect increasing the values of physiological variables and significant reductions in joint range of motion.

Report from the June Trigger and Physics Week

The week of June 4th saw the 5th ATLAS Trigger and Physics week at CERN. The meeting, bringing together people working in the trigger, data preparation, detector combined-performance and physics groups, aimed at focusing work and discussions on preparing ATLAS for first data-taking. The meeting started on Monday afternoon with a set of plenary presentations on topics ranging from software status and validation, the ATLAS analysis model and its implications for the computing model, and initial ideas for trigger menus for the expected LHC start-up luminosity of 1031cm-2s-1. There was also a report from Peter Jenni on the expected LHC start-up schedule. The participation exceeded the organisers' wildest dreams as the CERN Council Chamber (seating capacity 160) proved woefully inadequate to seat everyone. A packed Council Chamber for the opening plenary Tuesday was dedicated to parallel sessions of the trigger and combined performance groups. A great deal of progress was presented in all areas, notably on...

Radiation therapy after lumpectomy is a standard part of breast conserving therapy for invasive breast carcinoma. The most frequently used schedule worldwide is 60 Gy in 30 fractions in 6 weeks, a time commitment that sporadically may dissuade some otherwise eligible women from undertaking treatment. The purpose and primary endpoint of this perspective study is to evaluate feasibility and short-term late toxicity in a hypofractionated whole breast irradiation schedule. Between February and October 2008 we treated 65 consecutive patients with operable invasive early-stage breast cancer with a hypofractionated schedule of external beam radiation therapy. All patients were assigned to 39 Gy in 13 fractions in 3 weeks to the whole breast plus a concomitant weekly boost dose to the lumpectomy cavity of 3 Gy in 3 fractions. All the patients had achieved a median follow up of 24 months (range 21-29 months). At the end of treatment 52% presented grade 0 acute toxicity 39% had grade 1 and 9% had grade 2. At 6 months with all the patients assessed there were 34% case of grade 1 subacute toxicity and 6% of grade 2. At 12 months 43% and 3% of patients presented with clinical grade 1 and grade 2 fibrosis respectively and 5% presented grade 1 hyperpigmentation. The remaining patients were free of side effects. At 24 months, with 56 assessed, just 2 patients (3%) showed grade 2 of late fibrosis. The clinical results observed showed a reasonably good feasibility of the accelerated hypofractionated schedule in terms of acute, subacute and short-term late toxicity. This useful 13 fractions with a concomitant boost schedule seems, in selected patients, a biologically acceptable alternative to the traditional 30 days regime

Full Text Available The objective of the present randomized, open-label, naturalistic 8-week study was to compare the efficacy and safety of treatment with clonazepam (N = 63 and paroxetine (N = 57 in patients with panic disorder with or without agoraphobia. Efficacy assessment included number of panic attacks and clinician ratings of the global severity of panic disorders with the clinical global impression (CGI improvement (CGI-I and CGI severity (CGI-S scales. Most patients were females (69.8 and 68.4% in the clonazepam and paroxetine groups, respectively and age (mean ± SD was 35.9 ± 9.6 years for the clonazepam group and 33.7 ± 8.8 years for the paroxetine group. Treatment with clonazepam versus paroxetine resulted in fewer weekly panic attacks at week 4 (0.1 vs 0.5, respectively; P < 0.01, and greater clinical improvements at week 8 (CGI-I: 1.6 vs 2.9; P = 0.04. Anxiety severity was significantly reduced with clonazepam versus paroxetine at weeks 1 and 2, with no difference in panic disorder severity. Patients treated with clonazepam had fewer adverse events than patients treated with paroxetine (73 vs 95%; P = 0.001. The most common adverse events were drowsiness/fatigue (57%, memory/concentration difficulties (24%, and sexual dysfunction (11% in the clonazepam group and drowsiness/fatigue (81%, sexual dysfunction (70%, and nausea/vomiting (61% in the paroxetine group. This naturalistic study confirms the efficacy and tolerability of clonazepam and paroxetine in the acute treatment of patients with panic disorder.

Purpose The aim of the study was to evaluate the effect of phosphorus-32 colloid ([32P]) intracavitary irradiation on the treatment of patients with cystic craniopharyngiomas. Methods Twenty patients with predominantly cystic craniopharyngiomas were admitted from 1981 to 2006. Eleven patients had [32P] intracavitary irradiation by stereotactic injection or Ommaya cyst instillation as the primary treatment, and the remaining nine had the same internal irradiation as an adjuvant treatment after tumor resection. A calculated irradiation dose of 400~500 Gy per once was delivered to the cyst wall. Conclusion The patients were followed up ranging from 36 to 336 months; no operative morbidity or mortality was found from [32P] intracavitary irradiation. Fourteen patients (70%) had tumor progression and required further two to four times intracavitary irradiation. All 20 cases achieved tumor shrinkage or stabilization with effective outcome 3–6 months after the last [32P] therapy. For patients with cystic craniopharyngioma, [32P] administration by stereo-tactic injection or Ommaya cyst instillation is a safe and helpful option, which could improve the life quality, prolong the life span, and enhance the survival rate of cystic craniopharyngioma patients.

The purpose of this study was to examine the effects of a wider instantaneous input dynamic range (IIDR) setting on speech perception and comfort in quiet and noise for children wearing the Nucleus 24 implant system and the Freedom speech processor. In addition, children's ability to understand soft and conversational level speech in relation to aided sound-field thresholds was examined. Thirty children (age, 7 to 17 years) with the Nucleus 24 cochlear implant system and the Freedom speech processor with two different IIDR settings (30 versus 40 dB) were tested on the Consonant Nucleus Consonant (CNC) word test at 50 and 60 dB SPL, the Bamford-Kowal-Bench Speech in Noise Test, and a loudness rating task for four-talker speech noise. Aided thresholds for frequency-modulated tones, narrowband noise, and recorded Ling sounds were obtained with the two IIDRs and examined in relation to CNC scores at 50 dB SPL. Speech Intelligibility Indices were calculated using the long-term average speech spectrum of the CNC words at 50 dB SPL measured at each test site and aided thresholds. Group mean CNC scores at 50 dB SPL with the 40 IIDR were significantly higher (p Speech in Noise Test were not significantly different for the two IIDRs. Significantly improved aided thresholds at 250 to 6000 Hz as well as higher Speech Intelligibility Indices afforded improved audibility for speech presented at soft levels (50 dB SPL). These results indicate that an increased IIDR provides improved word recognition for soft levels of speech without compromising comfort of higher levels of speech sounds or sentence recognition in noise.

Full Text Available Dynamic key-guessing techniques, which exploit the property of AND operation, could improve the differential and linear cryptanalytic results by reducing the number of guessed subkey bits and lead to good cryptanalytic results for SIMON. They have only been applied in differential and linear attacks as far as we know. In this paper, dynamic key-guessing techniques are first introduced in integral cryptanalysis. According to the features of integral cryptanalysis, we extend dynamic key-guessing techniques and get better integral cryptanalysis results than before. As a result, we present integral attacks on 24-round SIMON32, 24-round SIMON48/72, and 25-round SIMON48/96. In terms of the number of attacked rounds, our attack on SIMON32 is better than any previously known attacks, and our attacks on SIMON48 are the same as the best attacks.

Full Text Available Background: Targeted ultraviolet B (T-UVB phototherapy in vitiligo is usually administered twice or thrice a week on non-consecutive days. It is difficult for many patients to adhere to this regimen, forcing them to discontinue treatment. Aim: The study aimed to compare the efficacy of twice-weekly and once-weekly targeted ultraviolet B phototherapy regimens in vitiligo. Methods: Sixty patients with non-segmental vitiligo on the face, neck or trunk were divided into two groups of 30 patients each. The patients in group A received targeted ultraviolet B twice weekly, while those in group B received targeted ultraviolet B once weekly. Repigmentation was monitored and graded as excellent (≥75% repigmentation, good (50−74% repigmentation and poor (<50% repigmentation. The extent of repigmentation at each body site (primary outcome measure, the number of doses required for initiation of pigmentation, and the cumulative dose of targeted ultraviolet B administered was calculated and compared between both groups. Results: A total of 90 lesions (48 in the twice weeklygroup and 42 in the once weekly group were treated on the face, neck and trunk. Excellent results were obtained in 62.5% (30/48 of lesions treated twice weekly, and 64.3% (27/42 in lesions treated once weekly. The mean number of doses required for initiation of pigmentation was 4.69 in the twice weekly group, and 4.35 in the once weekly group. The patients in the twice weekly group received a mean cumulative dose of 8.26 J/cm 2, while the once weekly group received 7.69 J/cm 2. No statistically significant differences were observed between the two groups with respect to the outcome, with respect to the total repigmentation, the number of doses till onset of pigmentation, as well as the cumulative dose of targeted UVB. Conclusion: Once-weekly targeted ultraviolet B phototherapy appears to be as efficacious as the twice-weekly regimen in vitiligo.

In order to confirming the possibility of to settle a dose range that takes place directly and not at random, a specific effect independently of the species that is were produced several similar organisms to three ornamental species took place via meristems cultivation: Petunia hybrid, Impatiens walleriana and Sprekelia formosissima, same that were irradiated in an irradiator Gamma cell 220, to different dose: 0, 3.5, 5.0, 7.5, 10, 12.5, 15, 17.5 and 20 Gy. Later on, of the plants treated via in vitro the subsequent generations were obtained until the M 4 . To determine the DL 50 and the possible good doses, the survival parameters, development, morphogenesis and height were evaluated during 8 weeks, interpreting based on them, the possible physiologic and genetic alterations induced by the radiation. The established DL 50 were: 7.5 Gy (Petunia), 19.0 Gy (Impatiens) and 12.0 Gy (Sprekelia). Based on the DL 50 of each species, a range of coincident dose settled down that produces a similar effect in the three species: a range of DL 23 to the DL 50 induces and alteration in the cytokinins production affecting directly in the leaves number, buds and plants taken place by meristem, also a range of DL 32 - DL 50 impacts in the auxins production altering to the radicule system. However, when being superimposed the dose is considered that the investigation should continue. (Author)

1990-01-01

The distribution and accumulation of the herbicide 2,4-D have been studied by 14 C labelling and by tracing due to the autoradiographic method in young plants of Euphorbia helioscopia L. (milkweed). Milkweed plants were grown in a greenhouse at 30deg C under 16 hrs. photoperiod for about two weeks. The two lower opposite leaves, the cotyledons, were used as sites for 14 C-labelled 2,4-D application. The autoradiograph of the whole plants revealed that labelled 2,4-D movement was predominantly basipetal into the root as well as acropetal into the shoot apex. The 2,4-D movement has by-passed all the matured leaves in its movement from active sources to active sinks. The microautoradiography indicated that 2,4-D can accumulate to a considerable amount both in the parenchyma of the pith and in the cortical cells. It is concluded that 2,4-D is transported through phloem cells when applied to the healthy long leaves. (author)

Clomiphene citrate (CC) is the first-line therapy for the induction of ovulation in infertile women with polycystic ovary syndrome (PCOS), but ∼20% of patients are unresponsive. The aim of the current study was to test the hypothesis that a 6-week intervention that consisted of structured exercise training (SET) and hypocaloric diet increases the probability of ovulation after CC in overweight and obese CC-resistant PCOS patients. A cohort of 96 overweight and obese CC-resistant PCOS patients was enrolled consecutively in a three-arm randomized, parallel, controlled, assessor-blinded clinical trial. The three interventions were: SET plus hypocaloric diet for 6 weeks (Group A); 2 weeks of observation followed by one cycle of CC therapy (Group B); and SET plus hypocaloric diet for 6 weeks, with one cycle of CC after the first 2 weeks (Group C). The primary end-point was the ovulation rate. Other reproductive data, as well as anthropometric, hormonal and metabolic data, were also collected and considered as secondary end points. After 6 weeks of SET plus hypocaloric diet, the ovulation rate was significantly (P =0.008) higher in Group C [12/32 (37.5%)] than in Groups A [4/32 (12.5%)] and B [3/32 (9.4%)] with relative risks of 3.9 [95% confidence interval (CI) 1.1-8.3; P = 0.035] and 4.0 (95% CI 1.2-12.8; P = 0.020) compared with Groups A and B, respectively. Compared with baseline, in Groups A and C, a significant improvement in clinical and biochemical androgen and insulin sensitivity indexes was observed. In the same two groups, the insulin sensitivity index was significantly (P hypocaloric diet was effective in increasing the probability of ovulation under CC treatment. The study was registered at Clinicaltrials.gov:NCT0100468.

The results of weight maintenance after initial weight loss are reported infrequently, although, when they have been reported, the outcomes are generally poor and weight regain is common. After an initial 12-week randomised intervention comparing all meal provision against a self-directed energy restriction, participants re-consented to participate in a follow-on study. Participants were given the option to choose to continue with the same dietary intervention (either all meal provision (provided free of charge) or self-directed diet) or change to the other diet for a further 12 weeks. Participants were followed up at 4-weekly intervals during both intervention periods (a total of 24 weeks), with a final follow up at 12 months. Eighty-five out of 86 individuals who completed the original 12-week randomised phase chose to continue on to the follow-up study. No significant differences in further weight loss between groups (P = 0.138) [mean (SEM): -3.4% (1.1%) for all meal provision only; -3.4% (0.6%) self-directed then all meal provision; -1.1% (1.2%) all meal provision then self-directed] were seen after a further 12 weeks. Meal provision for a total of 24 weeks resulted in 67% of individuals losing at least 10% body weight. The groups switching from self-directed dieting to meal provision (or vice versa) were the only groups to have a lower mean weight at 12 months than at the start of the follow-on study. Structured support for 24 weeks followed by 28 weeks of self-care can result in weight maintenance, with initial weight loss maintained at 12 months from enrolling on a 12-week weight loss intervention, with a 12-week follow-on period. © 2013 The British Dietetic Association Ltd.

For more than a decade, urinary free cortisol corrected for creatinine (OUFCC) has been used to assess the systemic bioactivity of inhaled corticosteroids in children with asthma. Paediatric normative ranges, however, have not been established. The aim of the present study was to define a preliminary range for OUFCC in Tanner stage 1 children. A post hoc analysis was performed of 26 Tanner stage one children (aged 5-11 years) with mild asthma only requiring prn (pro re nata) treatment with short-acting β 2 -agonists, who participated in a 3-way cross-over knemometry study. The study comprised a run-in, two washout periods and three treatment periods (2 weeks each). Urine was collected at the end of each period. A normative range was derived using the 95% prediction interval for the geometric mean OUFCC, calculated from run-in and washout periods. Twenty-six children contributed 41 OUFCC values. The geometric mean OUFCC was 9.0 nmol/mmol (95% PI: 3.6, 22.7 nmol/mmol). The OUFCC preliminary normative range was 3.6 to 22.7 nmol/mmol in Tanner stage one children. A larger study in healthy children is warranted to confirm these findings and to assess potential differences in OUFCC across developmental stages and age groups, and by gender and race. 2013-004719-32, CLINICALTRIALS.

While oral antidepressants reach efficacy after weeks, single-dose intravenous (i.v.) ketamine has rapid, yet time-limited antidepressant effects. We aimed to determine the efficacy and safety of single-dose i.v. ketamine augmentation of escitalopram in major depressive disorder (MDD). Thirty outpatients with severe MDD (17-item Hamilton Rating Scale for Depression total score ⩾ 24) were randomized to 4 weeks double-blind treatment with escitalopram 10 mg/day+single-dose i.v. ketamine (0.5 mg/kg over 40 min) or escitalopram 10 mg/day + placebo (0.9% i.v. saline). Depressive symptoms were measured using the Montgomery-Asberg Depression Rating Scale (MADRS) and the Quick Inventory of Depressive Symptomatology - Self-Report (QIDS-SR). Suicidal ideation was evaluated with the QIDS-SR item 12. Adverse psychopathological effects were measured with the Brief Psychiatric Rating Scale (BPRS)-positive symptoms, Young Mania Rating Scale (YMRS) and Clinician Administered Dissociative States Scale (CADSS). Patients were assessed at baseline, 1, 2, 4, 24 and 72 h and 7, 14, 21 and 28 days. Time to response (⩾ 50% MADRS score reduction) was the primary outcome. By 4 weeks, more escitalopram + ketamine-treated than escitalopram + placebo-treated patients responded (92.3% v. 57.1%, p = 0.04) and remitted (76.9% v. 14.3%, p = 0.001), with significantly shorter time to response [hazard ratio (HR) 0.04, 95% confidence interval (CI) 0.01-0.22, p escitalopram + placebo, escitalopram + ketamine was associated with significantly lower MADRS scores from 2 h to 2 weeks [(peak = 3 days-2 weeks; effect size (ES) = 1.08-1.18)], QIDS-SR scores from 2 h to 2 weeks (maximum ES = 1.27), and QIDS-SR suicidality from 2 to 72 h (maximum ES = 2.24). Only YMRS scores increased significantly with ketamine augmentation (1 and 2 h), without significant BPRS or CADSS elevation. Single-dose i.v. ketamine augmentation of escitalopram was safe and effective in severe MDD, holding promise for speeding up

2009-01-01

Phosphorus-32 ( 32 P) is a routinely used bone pain palliation agent at our institute due to its cost, availability and proven efficacy with mild and self limiting myelo-suppression. Vitamin D is known to de-differentiate tumors and supposed to enhance calcium deposition onto metastatic foci with a hope of reducing the marrow effects. A pilot study showing an increase in the 99m Tc-MDP uptake by skeletal metastatic foci, using single pulse dose of Vitamin D, in some of the patients preceded this study and found the basis for this study. The aim of this study was to evaluate the role of 32 P alone and in combination with vitamin D in the palliation of bone pain from osseous metastases and to look for its clinical efficacy and reduction in marrow suppression in our clinical environment. 62 patients with extensive osteoblastic bone metastases were randomly divided into 3 groups. Group A received 32 P alone, group B combination therapy of 32 P and Vitamin D and group C Vitamin D alone. All these patients were evaluated by a standard protocol on broad parameters of pain reduction, reduction in analgesic consumption, improvement in quality of life and effect on bone marrow suppression at the end of 4th and 8th week post-therapy. Favorable response (≥25%) to treatment was recorded in 55% of cases in-group A, 81% in- group B and 9% in-group C. Reduction in pain score of 50% to 100% were obtained in two cases in group A and 10 in group B. A decrease in pain of 26% to 50% and ≤ 25% was observed in 10 (45%) and 4 (18%) cases respectively in group A, and 8 (36%) and 2 (9%) cases respectively in group B. Analgesic consumption was reduced in both the groups of 32 P, comparatively more in group B. The improvement in mobility and quality of life was observed to be better in group B than A and C. A decrease of white blood cells, hemoglobin level and platelets counts was observed in both groups of 32 P but no significant difference was noted in group A and B was noted at the end

Absence of magnetic long range order in Ba3ZnRu2O9. A spin-liquid candidate in the S = 3/2 dimer lattice

International Nuclear Information System (INIS)

Terasaki, Ichiro; Igarashi, Taichi; Nagai, Takayuki

2017-01-01

We have discovered a novel candidate for a spin liquid state in a ruthenium oxide composed of dimers of S = 3/2 spins of Ru 5+ , Ba 3 ZnRu 2 O 9 . This compound lacks a long range order down to 37 mK, which is a temperature 5000-times lower than the magnetic interaction scale of around 200 K. Partial substitution for Zn can continuously vary the magnetic ground state from an antiferromagnetic order to a spin-gapped state through the liquid state. This indicates that the spin-liquid state emerges from a delicate balance of inter- and intra-dimer interactions, and the spin state of the dimer plays a vital role. This unique feature should realize a new type of quantum magnetism. (author)

2014-01-01

Following current recommendations for preventing retinopathy of prematurity (ROP) involves screening a large number of patients. We performed a prospective study to establish a useful screening system for ROP prediction and we have determined that measuring serum levels of IGF1 at week three and the presence of sepsis have a high predictive value for the subsequent development of ROP. A total of 145 premature newborn, with birthweight <1500 g and/or <32 weeks gestational age, were enrolled. 26.9% of them showed some form of retinopathy. A significant association was found between the development of retinopathy and each of the following variables: early gestational age, low birthweight, requiring mechanical ventilation, oxygen treatment, intracranial haemorrhage, sepsis during the first three weeks, bronchopulmonary dysplasia, the need for erythrocyte transfusion, erythropoietin treatment, and low levels of serum IGF1 in the third week. A multiple logistic regression analysis was used to obtain curves for the probability of developing ROP, based on the main factors linked with ROP, namely serum levels of IGF1 and presence of sepsis. Such preclinical screening has the ability to identify patients with high-risk of developing retinopathy and should lead to better prediction for ROP, while at the same time optimising the use of clinical resources, both human and material.

Full Text Available A longitudinal and prospective study was carried out at two state-operated maternity hospitals in Belo Horizonte during 1996 in order to assess the weight of preterm appropriate-for-gestational-age newborns during the first twelve weeks of life. Two hundred and sixty appropriate-for-gestational-age preterm infants with birth weight <2500 g were evaluated weekly. The infants were divided into groups based on birth weight at 250-g intervals. Using weight means, somatic growth curves were constructed and adjusted to Count's model. Absolute (g/day and relative (g kg-1 day-1 velocity curves were obtained from a derivative of this model. The growth curve was characterized by weight loss during the 1st week (4-6 days ranging from 5.9 to 13.3% (the greater the percentage, the lower the birth weight, recovery of birth weight within 17 and 21 days, and increasingly higher rates of weight gain after the 3rd week. These rates were proportional to birth weight when expressed as g/day (the lowest and the highest birth weight neonates gained 15.9 and 30.1 g/day, respectively. However, if expressed as g kg-1 day-1, the rates were inversely proportional to birth weight (during the 3rd week, the lowest and the highest weight newborns gained 18.0 and 11.5 g kg-1 day-1, respectively. During the 12th week the rates were similar for all groups (7.5 to 10.2 g kg-1 day-1. The relative velocity accurately reflects weight gain of preterm infants who are appropriate for gestational age and, in the present study, it was inversely proportional to birth weight, with a peak during the 3rd week of life, and a homogeneous behavior during the 12th week for all weight groups.
