Abstract
BACKGROUND Brain injuries resulting from trauma and stroke are common and costly. Cooling therapy may reduce damage and potentially improve outcome. Head cooling targets the site of injury and may have fewer side effects than systemic cooling, but there has been no systematic review and the evidence base is unclear. OBJECTIVE To assess the effect of non-invasive head cooling after traumatic brain injury (TBI) and stroke on intracranial and/or core body temperature, functional outcome and mortality, determine adverse effects and evaluate cost-effectiveness. REVIEW METHODS Search strategy Major international databases [including MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature, Web of Science, the British Library's Electronic Table of Contents (Zetoc)], The Cochrane Library, trial registers, country-specific databases (including China, Japan), Google Scholar, hypothermia conference reports and reference lists of papers were searched with no publication or language restrictions. The searches were conducted from March 2010 to April 2011, with no back date restriction. Selection criteria For formal analysis of effect of head cooling on functional outcome and mortality: randomised controlled trials (RCTs) of non-invasive head cooling in TBI or stroke in adults (aged ≥ 18 years). RCT prespecified in protocol to include adequate randomisation and blinded outcome assessment. For assessment of effect on temperature and adverse effects of cooling methods/devices: studies of any type in TBI, stroke, cardiac arrest and neonatal hypoxic-ischaemic encephalopathy (adverse effects only). Data collection and analysis A study assessment and data collection form was developed and piloted. Data on functional outcome, mortality, temperature change and adverse effects of devices were sought and extracted. Two authors independently assessed RCTs for quality using the Cochrane Renal Group checklist. RESULTS Out of 46 head-cooling studies in TBI and stroke, there were no RCTs of suitable quality for formal outcome analysis. Twelve studies had useable data on intracranial and core body temperature. These included 99 patients who were cooled after TBI or stroke and 198 patients cooled after cardiac arrest. The data were too heterogeneous for a single summary measure of effect (many studies had no measure of spread) and are therefore presented descriptively. The most effective techniques for which there were adequate data (nasal coolant and liquid cooling helmets) could reduce intracranial temperature by ≥ 1 °C in 1 hour. The main device-related adverse effects were localised skin problems, which were generally mild and self-limiting. There were no suitable data for economic modelling, but an exploratory model of possible treatment effects and cost-effectiveness of head cooling in TBI was created using local patient data. LIMITATIONS We conducted extensive and sensitive searches but found no good-quality RCTs of the effect of head cooling on functional outcome that met the review inclusion criteria. Most trials were small and/or of low methodological quality. However, if the trial reports did not reflect the true quality of the research, there may be some excluded trials that should have been included. Temperature data were often poorly reported which made it difficult to assess the effect of head cooling on temperature. CONCLUSIONS Whether head cooling improves functional outcome or has benefits and fewer side effects compared with systemic cooling or no cooling could not be established. Some methods of head cooling can reduce intracranial temperature, which is an important first step in determining effectiveness, but there is insufficient evidence to recommend its use outside of research trials. The principal recommendations for research are that active cooling devices show the most promise for further investigation and more robust proof of concept of intracranial and core body temperature reduction with head cooling is required, clearly showing whether temperature has changed and by how much.

Abstract
Testing of composite fecal (environmental) samples from high traffic areas in dairy herds has been shown to be a cost-effective and sensitive method for classification of herd status for Mycobacterium avium subsp. paratuberculosis (MAP). In the National Animal Health Monitoring System's (NAHMS) Dairy 2007 study, the apparent herd-level prevalence of MAP was 70.4% (369/524 had ≥ 1 culture-positive composite fecal samples out of 6 tested). Based on these data, the true herd-level prevalence (HP) of MAP infection was estimated using Bayesian methods adjusting for the herd sensitivity (HSe) and herd specificity (HSp) of the test method. The Bayesian prior for HSe of composite fecal cultures was based on data from the NAHMS Dairy 2002 study and the prior for HSp was based on expert opinion. The posterior median HP (base model) was 91.1% (95% probability interval, 81.6 to 99.3%) and estimates were most sensitive to the prior for HSe. The HP was higher than estimated from the NAHMS Dairy 1996 and 2002 studies but estimates are not directly comparable with those of prior NAHMS studies because of the different testing methods and criteria used for herd classification.

Abstract
PURPOSE To develop a more efficient monthly quality assurance (QA) process by utilizing one detector with multiple setups instead of multiple detectors with multiple setups. METHOD The Sun Nuclear IC Profiler was used to measure machine output, transverse profiles, and depth-dose profiles. The IC Profiler contains 251 ionization chambers aligned in the X, Y, and diagonal axes, and was designed to measure machine output and transverse profiles. In order to measure depth-doses, a Lucite compensator with an angled surface was fabricated. To test the capability of the detector, a proton beam of 10.5 cm range in water was used. The distal edge coincided with the overall water equivalent depth upstream of the detector on central axis. The measurement was repeated with an additional 1.0 mm of solid water placed in front of the detector. The measured profiles from both measurements were compared to quantify the IC Profiler response for a small range change. RESULTS The IC Profiler performs within vendor specification for measuring machine output and transverse profiles. When measuring depth-doses with an angled compensator, the IC profiler measures a change in profile along central axis of 17.0% for a 1.0mm range change. Based on overall reproducibility of the beam delivery system, the IC profiler is capable of detecting 0.3 mm range shift. Therefore, the sensivity of the IC profiler response is suffficient to detect sub millimeter changes in delivered range. CONCLUSION The Sun Nuclear IC Profiler is capable of measuring machine output, transverse profiles, and depth-dose profile constancy with a high degree of accuracy and precision. Using a single detector for all beam measurements increases the overall QA efficiency by reducing multiple detector overhead while not sacrificing the accuracy and precision of the measurements.

Abstract
Injuries suffered by student athletes not only affect their physical ability to perform in sport but also have psychological effects as well. The purpose of this study was to examine student athletes' perceptions, expectations, and satisfaction of the social support provided by their strength and conditioning coach (SC) during the later reconditioning stage of their rehabilitation and their views on the overall level of importance of each type of social support. One hundred and sixty-five participants aged 20.21 ± 1.32 years from 6 Division I Universities in the Midwest region of the USA completed the modified Social Support Survey. The results of a chi-square test assessing the responses for 6 types of social support provided by SCs based on athletes' age, gender, and sport revealed a significant difference (χ2[13,105] = 26.46, p = 0.015) for listening support differing by sport. A significant difference (χ2[13,105] = 267.74, p = 0.010) was also revealed for reported emotional challenge by sport. Results showed that the SC had a significant psychosocial impact on student-athletes' overall psychological well-being during reconditioning. This study provides evidence of the vital psychosocial role that SCs can play during an injured student-athlete's reconditioning program.

Abstract
BACKGROUND Efficiently delivered interventions to reduce HIV, malaria, and diarrhea are essential to accelerating global health efforts. A 2008 community integrated prevention campaign in Western Province, Kenya, reached 47,000 individuals over 7 days, providing HIV testing and counseling, water filters, insecticide-treated bed nets, condoms, and for HIV-infected individuals cotrimoxazole prophylaxis and referral for ongoing care. We modeled the potential cost-effectiveness of a scaled-up integrated prevention campaign. METHODS We estimated averted deaths and disability-adjusted life years (DALYs) based on published data on baseline mortality and morbidity and on the protective effect of interventions, including antiretroviral therapy. We incorporate a previously estimated scaled-up campaign cost. We used published costs of medical care to estimate savings from averted illness (for all three diseases) and the added costs of initiating treatment earlier in the course of HIV disease. RESULTS Per 1000 participants, projected reductions in cases of diarrhea, malaria, and HIV infection avert an estimated 16.3 deaths, 359 DALYs and $85,113 in medical care costs. Earlier care for HIV-infected persons adds an estimated 82 DALYs averted (to a total of 442), at a cost of $37,097 (reducing total averted costs to $48,015). Accounting for the estimated campaign cost of $32,000, the campaign saves an estimated $16,015 per 1000 participants. In multivariate sensitivity analyses, 83% of simulations result in net savings, and 93% in a cost per DALY averted of less than $20. DISCUSSION A mass, rapidly implemented campaign for HIV testing, safe water, and malaria control appears economically attractive.

Abstract
Background Delivery of community-based prevention services for HIV, malaria, and diarrhea is a major priority and challenge in rural Africa. Integrated delivery campaigns may offer a mechanism to achieve high coverage and efficiency. Methods We quantified the resources and costs to implement a large-scale integrated prevention campaign in Lurambi Division, Western Province, Kenya that reached 47,133 individuals (and 83% of eligible adults) in 7 days. The campaign provided HIV testing, condoms, and prevention education materials; a long-lasting insecticide-treated bed net; and a water filter. Data were obtained primarily from logistical and expenditure data maintained by implementing partners. We estimated the projected cost of a Scaled-Up Replication (SUR), assuming reliance on local managers, potential efficiencies of scale, and other adjustments. Results The cost per person served was $41.66 for the initial campaign and was projected at $31.98 for the SUR. The SUR cost included 67% for commodities (mainly water filters and bed nets) and 20% for personnel. The SUR projected unit cost per person served, by disease, was $6.27 for malaria (nets and training), $15.80 for diarrhea (filters and training), and $9.91 for HIV (test kits, counseling, condoms, and CD4 testing at each site). Conclusions A large-scale, rapidly implemented, integrated health campaign provided services to 80% of a rural Kenyan population with relatively low cost. Scaling up this design may provide similar services to larger populations at lower cost per person.

Abstract
Background/Objectives: Protein concentration is lower in human milk (HM) than in infant formula. The objective of this study was to evaluate the effect of an α-lactalbumin-enriched formula with a lower protein concentration on infant growth, protein markers and biochemistries. Subjects/Methods: Healthy term formula-fed (FF) infants 5–14 days old were randomized in this controlled, double-blind trial to standard formula (SF: 14.1 g/l protein, 662 kcal/l) group (n=112) or experimental formula (EF: 12.8 g/l protein, 662 kcal/l) group (n=112) for 120 days; a HM reference group (n=112) was included. Primary outcome was weight gain (g/day) from D0 to D120. Secondary outcomes included serum albumin, plasma amino acids insulin and incidence of study events. Anthropometric measures were expressed as Z-scores using 2006 World Health Organization growth standards. Results: A total of 321 of the 336 infants (96%) who enrolled, completed the study. Mean age was 9.6 (±2.9) days; 50% were girls. Mean weight gain (g/day) did not significantly differ between SF vs EF (P=0.67) nor between EF vs HM (P=0.11); however weight gain (g/day) was significantly greater in the SF vs HM group (P=0.04). At day 120, mean weight-for-age Z-score (WAZ) and weight-for-length Z-score (WLZ) did not significantly differ between SF vs EF nor EF vs HM; however the WAZ was significantly greater in SF vs HM (P=0.025). Secondary outcomes were within normal ranges for all groups. Incidence of study events did not differ among groups. Conclusions: α-Lactalbumin-enriched formula containing12.8 g/l protein was safe and supported age-appropriate growth; weight gain with EF was intermediate between SF and HM groups and resulted in growth similar to HM-fed infants in terms of weight gain, WAZ and WLZ.

Abstract
Background Respiratory syncytial virus (RSV) is an important pathogen causing annual epidemics of bronchiolitis and pneumonia among infants worldwide. High-risk infants currently receive RSV prophylaxis with palivizumab, a humanized RSV monoclonal antibody (MAb). In preclinical in vitro and in vivo (cotton-rat model) studies, motavizumab, a new RSV MAb, was shown to have greater anti-RSV activity than palivizumab. Motavizumab is currently under review for licensing approval. Since both MAbs may be available concurrently, this study evaluated their safety and tolerability when administered sequentially during the same RSV season. Methods Between April 2006 and May 2006, 260 high-risk infants were randomly assigned 1:1:1 to receive monthly intramuscular injections: 2 doses of motavizumab followed by 3 doses of palivizumab (M/P); 2 doses of palivizumab followed by 3 doses of motavizumab (P/M); or 5 doses of motavizumab (control). Adverse events (AEs, serious AEs [SAEs]), development of antidrug antibody (ADA), and serum drug trough concentrations were assessed. Results Most children received all 5 doses (246/260 [94.6%]) and completed the study (241/260 [92.7%]). While overall AE rates were similar (mostly level 1 or 2 in severity), SAEs and level 3 AEs occurred more frequently in the M/P group (SAEs: 22.9% M/P, 8.4% P/M, 11.8% motavizumab only; level 3 AEs: 15.7% M/P, 6.0% P/M, 6.5% motavizumab only). This trend in AE rates occurred before and after switching from motavizumab to palivizumab, suggesting a cause other than the combined regimen. Frequencies of AEs judged by the investigator to be related to study drug were similar among groups. Two deaths occurred on study (both in the M/P group, before palivizumab administration); neither was considered by the site investigator to be related to study drug. Mean serum drug trough concentrations were comparable among groups; ADA detection was infrequent (5.1% or less of any group). Conclusions The conclusions drawn from this study are limited by the small sample size per group. However, within this small study, overall AE rates, serum drug trough concentrations, and development of ADA associated with administering motavizumab and palivizumab sequentially to high-risk children appear comparable to administering motavizumab alone during the same RSV season.

Abstract
Anecdotal beliefs that exercise is an effective treatment for primary dysmenorrhoea have prevailed for many years although evidence is contradictory. Previous studies have also contained a number of methodological inadequacies. A questionnaire that assessed menstrual pain and levels of exercise was administered to 654 university students. Attempts were made to blind the purpose of the study. A response rate of 91.3% (597/654) was obtained. Analyses showed no association between participation in exercise and primary dysmenorrhoea. Prospective studies would be useful in further research.

Abstract
OBJECTIVE Palivizumab reduces respiratory syncytial virus (RSV) hospitalization in children at high risk by approximately 50% compared with placebo. We compared the efficacy and safety of motavizumab, an investigational monoclonal antibody with enhanced anti-RSV activity in preclinical studies, with palivizumab. METHODS This randomized, double-blind, multinational, phase 3, noninferiority trial assessed safety and RSV hospitalization in 6635 preterm infants aged <or=6 months at enrollment or children aged <or=24 months with chronic lung disease of prematurity who received 15 mg/kg palivizumab or motavizumab monthly. Secondary end points included outpatient medically attended lower respiratory tract infections (MALRIs), RSV-specific LRIs, otitis media, antibiotic use, development of antimotavizumab antibodies, and motavizumab serum concentrations. RESULTS Motavizumab recipients had a 26% relative reduction in RSV hospitalization compared with palivizumab recipients, achieving noninferiority. Motavizumab was superior to palivizumab for reduction of RSV-specific outpatient MALRIs (50% relative reduction). Overall, adverse events (AEs) were not significantly different between groups. Cutaneous events were reported in 2 percentage points more motavizumab recipients (7.2% vs 5.1%); most were mild, but 0.3% resulted in dosing discontinuation. Antidrug antibodies (ADA) were detected in 1.8% of motavizumab recipients. Patients with anti-drug antibody reported 6 RSV events and 17 cutaneous events. CONCLUSIONS Children receiving prophylaxis with motavizumab or palivizumab had low rates of RSV hospitalization; motavizumab recipients experienced 50% fewer RSV MALRIs than palivizumab recipients. AEs were similar in both groups, although cutaneous AEs were higher for motavizumab recipients. Motavizumab may offer an improved alternative in prophylaxis for serious RSV disease in infants and children at high risk.
