Abstract
BACKGROUND It is more common for women in both high- and low-income countries giving birth in health facilities, to labour in bed. There is no evidence that this is associated with any advantage for women or babies, although it may be more convenient for staff. Observational studies have suggested that if women lie on their backs during labour this may have adverse effects on uterine contractions and impede progress in labour, and in some women reduce placental blood flow. OBJECTIVES To assess the effects of encouraging women to assume different upright positions (including walking, sitting, standing and kneeling) versus recumbent positions (supine, semi-recumbent and lateral) for women in the first stage of labour on duration of labour, type of birth and other important outcomes for mothers and babies. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 January 2013). SELECTION CRITERIA Randomised and quasi-randomised trials comparing women randomised to upright versus recumbent positions in the first stage of labour. DATA COLLECTION AND ANALYSIS We used methods described in the Cochrane Handbook for Systematic Reviews of Interventions for carrying out data collection, assessing study quality and analysing results. Two review authors independently evaluated methodological quality and extracted data for each study. We sought additional information from trial authors as required. We used random-effects analysis for comparisons in which high heterogeneity was present. We reported results using the average risk ratio (RR) for categorical data and mean difference (MD) for continuous data. MAIN RESULTS Results should be interpreted with caution as the methodological quality of the 25 included trials (5218 women) was variable.For Comparison 1: Upright and ambulant positions versus recumbent positions and bed care, the first stage of labour was approximately one hour and 22 minutes shorter for women randomised to upright as opposed to recumbent positions (average MD -1.36, 95% confidence interval (CI) -2.22 to -0.51; 15 studies, 2503 women; random-effects, T(2) = 2.39, Chi(2) = 203.55, df = 14, (P < 0.00001), I(2) = 93%). Women who were upright were also less likely to have caesarean section (RR 0.71, 95% CI 0.54 to 0.94; 14 studies, 2682 women) and less likely to have an epidural (RR 0.81, 95% CI 0.66 to 0.99, nine studies, 2107 women; random-effects, T(2) = 0.02, I(2) = 61%). Babies of mothers who were upright were less likely to be admitted to the neonatal intensive care unit, however this was based on one trial (RR 0.20, 95% CI 0.04 to 0.89, one study, 200 women). There were no significant differences between groups for other outcomes including duration of the second stage of labour, or other outcomes related to the well being of mothers and babies.For Comparison 2: Upright and ambulant positions versus recumbent positions and bed care (with epidural: all women), there were no significant differences between groups for outcomes including duration of the second stage of labour, or other outcomes related to the well being of mothers and babies. AUTHORS' CONCLUSIONS There is clear and important evidence that walking and upright positions in the first stage of labour reduces the duration of labour, the risk of caesarean birth, the need for epidural, and does not seem to be associated with increased intervention or negative effects on mothers' and babies' well being. Given the great heterogeneity and high performance bias of study situations, better quality trials are still required to confirm with any confidence the true risks and benefits of upright and mobile positions compared with recumbent positions for all women. Based on the current findings, we recommend that women in low-risk labour should be informed of the benefits of upright positions, and encouraged and assisted to assume whatever positions they choose.

Abstract
BACKGROUND Western Australian (WA) perinatal statistics indicate an 8 percent decrease in smoking by pregnant women from 1999 to 2009. Despite the success of cessation interventions, the incidence of tobacco smokers among young pregnant women remains a cause for concern. To inform development of an appropriate suite of interventions, a qualitative study was undertaken to gain insight into the perceived challenges and enablers young pregnant women encounter when attempting to modify their smoking. METHOD A hypothetical scenario and interview questions were used: if a young pregnant woman decided to decrease or stop her smoking 1) what could assist her, and 2) what are the challenges that she would need to overcome? Thematic analysis was conducted. Our sample included English-speaking pregnant women recorded as a smoker, 16 to 24 years of age, and attending antenatal services at a public maternity hospital. RESULTS Thirty-six women participated in an interview. "Habit" was noted as the key theme under perceived challenges and incorporated three subthemes: learn to deal with stress; the urge for a smoke; and not being left out. Concern over the health of their baby emerged as the main theme and enabler to change behavior. Four subthemes were extracted around keeping their baby healthy: getting the facts; you need someone; something you can take to help; and keeping your mind off it. CONCLUSIONS Our findings highlight the complex issues around smoking for young pregnant WA women. Insight into these challenges and enablers may inform development of more suitable interventions to address the unique needs of this group of pregnant women.

Abstract
PLGA/pluronic F127 based nerve guidance conduits (NGCs) for peripheral nerve regeneration offer excellent potential for clinical use. To date, little emphasis has been directed towards the effect of pluronic F127 on their subsequent mechanical properties as a function of degradation time or the physiological environment. This report was designed to redress the balance. This study synthesised 5 groups of 20wt% PLGA NGCs with varied additions of pluronic F127 (range 0-5wt%) to obtain Young's Moduli (E) in the range of 7-107MPa, depending on degradation conditions and pluronic F127 content.

Abstract
The new National Institute for Health and Clinical Excellence (NICE) guidance cites genitourinary (GU) medicine clinics as one setting where screening for alcohol-use disorders should be part of routine clinical practice. Northumberland GU medicine service has routinely used the Fast Alcohol Screening Tool (FAST) since June 2009. An audit of all first attendees to the service in April 2010 (n = 256) was carried out. This audit found that the FAST questionnaire was acceptable to both patients and staff (uptake of 95.7%). Statistically significant associations between excessive alcohol and higher rates of unprotected sex (P < 0.01), an increased number of sexual partners (P < 0.01) and higher rates of sexually transmitted infection (STI) diagnosis (P < 0.05) were also demonstrated.

Abstract
2550 Background: The effect of food on the bioavailability and PK of panobinostat (PAN) are of considerable importance in allowing appropriate dosing of chronic oral cancer therapy. Methods: Patients (pts) with advanced cancer received 20 mg PAN twice a week of a 21-day cycle and were randomized to receive 1 of 6 treatment sequences where PAN PK was evaluated weekly under fasting, high fat and normal breakfast. Serial blood samples were collected for PAN PK evaluations on Days 1, 8, and 15. Plasma PAN concentrations were measured by LC-MS-MS. PK parameters were estimated by using non-compartmental analysis. Results: A total of 34 patients were evaluated. PAN was generally well tolerated with no significant lab, ECG, or other safety concerns. No residual PAN concentrations were detected in pre-dose samples on Days 8 and 15. Meal conditions and PAN PK parameters expressed as either mean (CV%) or median [range] or ratio are described in the Table . The overall exposure and inter-patient variability (CV 59%) remained unchanged with or without food, whereas Cmax was transiently reduced (<45%) by food. Although tumor response was not the main objective, a pt with recurrent RCC, following sunitinib and sorafenib treatment, has achieved a PR after ∼6 cycles of PAN and is continued on study. Conclusions: Since the overall extent of absorption and variability was not changed due to food, PAN administration with or without food is unlikely to significantly impact systemic PAN exposure in cancer patients. PAN can be administered without regards to food in future studies. [Table: see text] [Table: see text]

Abstract
BACKGROUND It is more common for women in the developed world, and those in low-income countries giving birth in health facilities, to labour in bed. There is no evidence that this is associated with any advantage for women or babies, although it may be more convenient for staff. Observational studies have suggested that if women lie on their backs during labour this may have adverse effects on uterine contractions and impede progress in labour. OBJECTIVES The purpose of the review is to assess the effects of encouraging women to assume different upright positions (including walking, sitting, standing and kneeling) versus recumbent positions (supine, semi-recumbent and lateral) for women in the first stage of labour on length of labour, type of delivery and other important outcomes for mothers and babies. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (November 2008). SELECTION CRITERIA Randomised and quasi-randomised trials comparing women randomised to upright versus recumbent positions in the first stage of labour. DATA COLLECTION AND ANALYSIS We used methods described in the Cochrane Handbook for Systematic Reviews of Interventions for carrying out data collection, assessing study quality and analysing results. A minimum of two review authors independently assessed each study. MAIN RESULTS The review includes 21 studies with a total of 3706 women. Overall, the first stage of labour was approximately one hour shorter for women randomised to upright as opposed to recumbent positions (MD -0.99, 95% CI -1.60 to -0.39). Women randomised to upright positions were less likely to have epidural analgesia (RR 0.83 95% CI 0.72 to 0.96).There were no differences between groups for other outcomes including length of the second stage of labour, mode of delivery, or other outcomes related to the wellbeing of mothers and babies. For women who had epidural analgesia there were no differences between those randomised to upright versus recumbent positions for any of the outcomes examined in the review. Little information on maternal satisfaction was collected, and none of the studies compared different upright or recumbent positions. AUTHORS' CONCLUSIONS There is evidence that walking and upright positions in the first stage of labour reduce the length of labour and do not seem to be associated with increased intervention or negative effects on mothers' and babies' wellbeing. Women should be encouraged to take up whatever position they find most comfortable in the first stage of labour.

Abstract
OBJECTIVES Investigations were carried out to determine aflatoxin levels in household maize in Makueni District and to correlate aflatoxin levels to maize drying and storage practices. Also, aflatoxin exposure in villages that reported aflatoxicosis cases in 2005 was compared with that in villages that did not report cases to assess whether aflatoxin exposure levels could be used to identify high-risk villages for targeted prevention interventions. DESIGN A cross-sectional study. SETTING Three divisions of Makueni district, Kibwezi, Makindu and Mtito Andei in Eastern Province, Kenya. SUBJECTS Ninety six households were surveyed, and 104 maize samples were analysed for total aflatoxin levels from June to July 2005. The households were selected from high and low aflatoxicosis risk areas. RESULTS Out of the 104 maize samples collected from 96 households, 37 (35.5%) had aflatoxin levels above the World Health Organisation (WHO) recommended maximum limit of 20 ppb. All of these samples were homegrown or purchased. Twenty one samples (20.1%) had levels above 100 ppb. Eleven (10.6%) had extremely high levels above 1000 ppb. No relief supply maize had aflatoxin levels above the WHO maximum limit. CONCLUSION High levels of aflatoxin in homegrown and purchased maize suggested that aflatoxin exposure was widespread.

Abstract
Management of Malignant Gliomas continues to be a challenge. We prospectively studied the role of adding weekly Paclitaxel to Fractionated Stereotactic Radiation Therapy (FSRT) in the treatment of Malignant Gliomas. Twenty-three Glioblastoma Multiforme and two Anaplastic Astrocytoma were studied. Patients received 46 Gy at 2 Gy/fraction followed by a boost utilizing FSRT at a fraction of 2.5 Gy for 8 fractions. Paclitaxel is delivered concomitantly at 150 mg/m(2) weekly for six cycles. Eighteen patients had pharmacokinetic assays of Paclitaxel levels. All patients were followed until death or for a maximum of 36 months. The overall survival of the whole group was 14 months. The median survival for RPA prognostic classes III, IV, V, and VI were 20, 14, 12, and 11 months. Higher survival (14 months) was noted in the subtherapeutic phenytoin level group compared to 10 months in the therapeutic group (P=0.271). No grade 4 CTCAE (version 3.0) toxicities were observed. Enhanced survival was demonstrated with gross tumor resection (20.8 months), KPS > or =80 (18.7 months) and age < or =60 years (27 months) as compared to subtotal resection or biopsy (12.1 months, P< 0.005), KPS < or =70 (10.8 months, P=0. 005) and older age > 60 (10.46 months, P=0.006), respectively. Our study suggests that: i) the use of weekly Paclitaxel and FSRT in Gliomas is well tolerated with a survival of 14 months; ii) the regimen resulted in improvement of survival of RPA classes IV, V, VI; and iii) the use of FSRT boost may be studied with other chemotherapeutic agents to see if superior results can be attained.

Abstract
The objective of this study was to determine the direct cost of HIV adherence support programmes participating in a cross-site evaluation in the US. Data on the frequency, type, and setting of adherence encounters; providers' professions; and adherence tools provided were collected for 1,122 patients enrolled in 13 interventions at 9 sites. The site staff estimated the average duration of each type of encounter and national wage rates were used for labour costs. The median (range) adherence encounters/year among interventions was 16.5 (4.3-104.6) per patient; encounters lasted 24.6 (8.9-40.9) minutes. Intervention direct cost was correlated with the average frequency of encounters (r = 0.57), but not with encounter duration or providers' professions. The median direct cost/month was 35 dollars(5 dollars-58 dollars) per patient, and included direct provider costs (66%); incentives (17%); reminders and other tools (8%); and direct administrative time, provider transportation, training, and home delivery (9%). The median direct cost/month from a societal perspective, which includes patient time and travel costs, was 47 dollars(24 dollars-114 dollars) per patient. Adherence interventions with moderate efficacy costing < or =100 dollars/month have been estimated to meet a cost-effectiveness threshold that is generally accepted in the US. Payers should consider enhanced reimbursement for adherence support services.
