    Nutritional therapy and infectious diseases: a two-edged sword

    The benefits and risks of nutritional therapies in the prevention and management of infectious diseases in the developed world are reviewed. There is strong evidence that early enteral feeding of patients prevents infections in a variety of traumatic and surgical illnesses. There is, however, little support for similar early feeding in medical illnesses. Parenteral nutrition increases the risk of infection when compared to enteral feeding or delayed nutrition. The use of gastric feedings appears to be as safe and effective as small bowel feedings. Dietary supplementation with glutamine appears to lower the risk of post-surgical infections and the ingestion of cranberry products has value in preventing urinary tract infections in women

    Identification of boosted Higgs bosons decaying into b-quark pairs with the ATLAS detector at 13 TeV

    This paper describes a study of techniques for identifying Higgs bosons at high transverse momenta decaying into bottom-quark pairs, H→bb¯ , for proton–proton collision data collected by the ATLAS detector at the Large Hadron Collider at a centre-of-mass energy s√=13 TeV . These decays are reconstructed from calorimeter jets found with the anti- kt R=1.0 jet algorithm. To tag Higgs bosons, a combination of requirements is used: b-tagging of R=0.2 track-jets matched to the large-R calorimeter jet, and requirements on the jet mass and other jet substructure variables. The Higgs boson tagging efficiency and corresponding multijet and hadronic top-quark background rejections are evaluated using Monte Carlo simulation. Several benchmark tagging selections are defined for different signal efficiency targets. The modelling of the relevant input distributions used to tag Higgs bosons is studied in 36 fb −1 of data collected in 2015 and 2016 using g→bb¯ and Z(→bb¯)γ event selections in data. Both processes are found to be well modelled within the statistical and systematic uncertainties

    Measurement of the inclusive cross-section for the production of jets in association with a Z boson in proton-proton collisions at 8 TeV using the ATLAS detector

    The inclusive cross-section for jet production in association with a Z boson decaying into an electron–positron pair is measured as a function of the transverse momentum and the absolute rapidity of jets using 19.9 fb −1 of s√=8 TeV proton–proton collision data collected with the ATLAS detector at the Large Hadron Collider. The measured Z + jets cross-section is unfolded to the particle level. The cross-section is compared with state-of-the-art Standard Model calculations, including the next-to-leading-order and next-to-next-to-leading-order perturbative QCD calculations, corrected for non-perturbative and QED radiation effects. The results of the measurements cover final-state jets with transverse momenta up to 1 TeV, and show good agreement with fixed-order calculations

    <p>Abstract</p> <p>Background</p> <p>Pakistan was among the leading countries in south Asia which started the family planning program in late 50s, forecasting the need to control the population. Despite this early intervention, fertility rate has declined but slower in Pakistan as compared to most other Asian countries. Pakistan has almost a stagnant contraceptive prevalence rate for more than a decade now, perhaps owing to the inadequate performance of the family planning programs. The provision and use of long term contraceptives such as IUCD has always been low (around 2%) and associated with numerous issues. Married women who want to wait before having another child, or end childbearing altogether, are not using any long term method of contraception.</p> <p>Methodology</p> <p>A descriptive qualitative study was conducted from May to July 2012, to explore and understand the perceptions of women regarding the use of IUCDs and to understand the challenges/issues at the service provider’s end. Six FGDs with community women and 12 in-depth interviews were conducted with family planning providers. The data was analyzed using the Qualitative Content Analysis approach.</p> <p>Results</p> <p>The study revealed that the family planning clients are reluctant to use IUCDs because of a number of myths and misconceptions associated with the method. They have reservations about the provider’s capability and quality of care at the facility. Private health providers are not motivated and are reluctant to provide the IUCDs because of inadequate counseling skills, lack of competence and improper supporting infrastructure. Government programs either do not have enough supplies or trained staff to promote the IUCD utilization.</p> <p>Conclusion</p> <p>Besides a well-designed community awareness campaign, providers’ communication and counseling skills have to be enhanced, as these are major contributing factors in IUCD acceptance. Ongoing training of all family planning service providers in IUCD insertion is very important, along with strengthening of their services.</p
