A decade of norovirus disease risk among older adults in upper-middle and high income countries: a systematic review
The quest according to Julien Gracq : a study of the search for the beyond in Gracq\u27s three novels and his play Le roi pêcheur
Julien Gracq\u27 s quest for the au-delà is similar in many ways to the Surrealists\u27 attempts to get in touch with the Beyond and to find that mythical and ideal point where binary oppositions are no longer contradictory but complementary. However, he differs greatly from the Surrealists in that his writing is anything but automatic . Whereas he acknowledges being influenced by the Surrealists\u27 ideas and by the works of certain authors, notably Goethe, Wagner, and Edgar Allen Poe, his works are a unique and carefully constructed web of style techniques, double-entendres, intertextual references, poetic devices, and a deliberate blurring of the dividing line between clear and obscure
A decade of norovirus disease risk among older adults in upper-middle and high income countries : a systematic review
BACKGROUND: Noroviruses (NoVs) are the most common cause of acute gastroenteritis (AGE) causing both sporadic and outbreak-associated illness. Norovirus (NoV) infections occur across all ages but certain sub-groups are considered at increased risk due to heightened transmission and/or symptom severity. Older adults are potentially at high risk of NoV-associated illness due to frequent outbreaks in long-term care facilities (LTCFs) and severe health outcomes following infection. Elucidation of NoV risk among older adults will support prevention, treatment and control efforts. METHODS: We conducted a systematic literature review to summarize the published risk estimates of NoV-associated illness, hospitalization and death among individuals aged 65 years and older. A structured search using defined NoV and gastroenteritis (GE) terms was performed in the PubMed and EMBASE databases of human studies published between January 1, 2003 and May 16, 2013. RESULTS: We identified 39 studies from high income (HI) and upper-middle income (UMI) countries. Thirty-six percent of publications provided risk estimates based on laboratory-confirmed or epidemiologically-linked population-based surveillance data using molecular diagnostic methods. Over the study period, estimated annual NoV rates and extrapolated number of cases among older adults in HI and UMI countries were: 29-120/10,000 or 1.2–4.8 million NoV-associated illnesses; 18–54/10,000 or 723,000–2.2 million NoV-associated outpatient visits; 1–19/10,000 or 40,00–763,000 NoV-associated inpatient visits; 0.04–0.32/10,000 or 2000–13,000 NoV-associated deaths. NoV was responsible for approximately 10–20 % of GE hospitalizations and 10–15 % of all-cause GE deaths among older adults. Older adults experienced a heightened risk of nosocomial infections. Those in LTCFs experience frequent NoV outbreaks and the range in attack rates was 3–45 %, case hospitalization rates 0.5–6 % and case fatality rates 0.3–1.6 %. CONCLUSIONS: Older adults are at increased risk of severe NoV-associated health outcomes. NoV-associated hospitalization rates were higher, more severe, resulted in longer stays and incurred greater costs than for younger patients. NoV-associated mortality rates were approximately 200 % higher among individuals 65 years and older compared to <5 years. The burden of NoV among older adults is expected to rise along with societal aging and increased need for institutionalized care. NoV prevention in older adults, including potential vaccination, may significantly impact risk of severe illness
Neonatal vaccination with an acellular pertussis vaccine accelerates the acquisition of pertussis antibodies in infants
OBJECTIVES: Because young infants are at highest risk of pertussis complications, this study assessed whether neonatal acellular pertussis (aP) vaccination could provide earlier immunity. STUDY DESIGN: Neonates (n = 121) were randomly assigned (1:1) to receive either aP or hepatitis B vaccine (HBV) (controls) vaccine at birth, followed by vaccination with DTaP-HBV-IPV/Hib at 2, 4 and 6 months. Immune responses were measured. Reactogenicity was assessed for 7 days after each dose. RESULTS: The aP birth dose was followed by few adverse events. Reactogenicity of subsequent vaccine doses did not differ between groups. Seven serious adverse events were reported from each group; none were related to the study vaccines. At 3 months of age, vaccination with aP at birth had induced significantly higher antibody responses to the 3 pertussis antigens compared with controls. At 7 months, geometric mean/concentrations of antibodies against pertussis antigens were similar in both groups, and all subjects had reached "seroprotective" antibody concentrations against diphtheria, tetanus, and poliovirus types 1, 2, and 3. Geometric mean/concentrations of antibodies to haemophilus influenzae type b (Hib) and HBV were significantly lower in the aP group. CONCLUSIONS: Early neonatal immunization with aP was safe, well tolerated, and resulted in earlier antibody responses, seen after the first dose of a DTaP combination vaccine. Birth dose of aP did not induce immunologic tolerance to pertussis antigens but appear to dampen responses to Hib and HBV vaccines
A method of amplification of a circularised nucleic acid probe
A method for amplifying a circular nucleic acid probe produced following interaction of a nucleic acid probe with a target sequence whereby the circular nucleic acid probe is enriched prior to amplification. Enrichment reduces the level of background amplification by removing any linear nucleic acid probes, and may be enzymatic or non-enzymatic. Amplification may be by rolling circle amplification. The probe may be a padlock probe. The terminal sequences of the probe may form non-contiguous duplexes with the probe circularised through ligation of a capture ligand or spacer nucleic acid molecule between the two terminal sequences. The capture ligand or spacer nucleic acid molecule may be labelled, such as with biotin. The method is used in applications involving the detection of specific nucleic acid sequences
The Burden of Childhood Pneumonia in the Developed World: A Review of the Literature
Background: Estimates of the disease burden from childhood pneumonia are available for most developed countries, but they are based mainly on models. Measured country-specific pneumonia burden data are limited to a few nations and differ in case definitions and case ascertainment methods. This review describes pneumonia disease burden in developed countries.Methods: We reviewed studies describing childhood pneumonia incidence in North America, Europe, Australia, New Zealand and Japan. Available estimates suggest that each year in developed countries there are up to 2.6 million cases of pneumonia, including 1.5 million hospitalized cases and around 3000 pneumonia deaths (compared with approximately 640 annual deaths from meningitis) in childre
Providing services for acute low-back pain: A survey of Australian physiotherapists
Objective: To determine whether physiotherapists avoid lumbar X-rays for acute non-specific low back pain and advise people to stay active. Methods: We conducted a cross sectional survey of Australian physiotherapists. 880 physiotherapists were randomly sampled from Victoria (495), South Australia (158), and Western Australia (227). Physiotherapists were asked which investigations they would order and interventions they would provide for five acute low back pain (LBP) presentations described in vignettes. Four of the five vignettes represented people who would not require a plain lumbar X-ray and would benefit from advice to stay active; one described a patient with a suspected vertebral fracture and would require a plain X-ray. Participants selected from a list of response options or provided free text responses. Results: Questionnaires were completed by 203 of 567 potentially eligible physiotherapists (response rate 36%). Across the four vignettes where an X-ray was not indicated, 75% (95%CI 71-78%) of physiotherapists reported they would practice concordant with the guidelines and not order an X-ray, and 62% (95%CI 57-66%) provided advice to stay active. Conclusions: Most physiotherapists report intended compliance with recommendations in Australian clinical practice guidelines (CPGs) regarding avoiding the use of X-rays and providing advice to stay active for people with simple acute low back pain, given a vignette based scenario. The majority of respondents reported that they would not advise bed rest. Possible opportunities to further enhance compliance need to be developed and tested to reinforce the role of CPGs in informing physiotherapy practice. © 2015 Elsevier Ltd
