    Risk Factors for West Nile Virus Neuroinvasive Disease, California, 2005

    Get PDF
    In 2005, 880 West Nile virus cases were reported in California; 305 case-patients exhibited neuroinvasive disease, including meningitis, encephalitis, or acute flaccid paralysis. Risk factors independently associated with developing neuroinvasive disease rather than West Nile fever included older age, male sex, hypertension, and diabetes mellitus

    Fostering global science networks in a Post-COVID-19 world

    To restrict the spread of COVID-19 disease, regional and national governments have implemented a range of communitybased measures. Physical distancing has closed offices and laboratories, canceled fieldwork and research cruises, and led to scientific productivity declines, notably of female scientists (Staniscuaski et al., 2020; Viglione, 2020; Vincent-Lamarr et al., 2020.) The cessation of international travel was an early measure that looks like it may be continuing for some time.info:eu-repo/semantics/publishedVersio

    Acute flaccid paralysis with anterior myelitis - California, June 2012-June 2014.

    Get PDF
    In August 2012, the California Department of Public Health (CDPH) was contacted by a San Francisco Bay area clinician who requested poliovirus testing for an unvaccinated man aged 29 years with acute flaccid paralysis (AFP) associated with anterior myelitis (i.e., evidence of inflammation of the spinal cord involving the grey matter including anterior horn cell bodies) and no history of international travel during the month before symptom onset. Within 2 weeks, CDPH had received reports of two additional cases of AFP with anterior myelitis of unknown etiology. Testing at CDPH's Viral and Rickettsial Disease Laboratory for stool, nasopharyngeal swab, and cerebrospinal fluid (CSF) did not detect the presence of an enterovirus (EV), the genus of the family Picornaviridae that includes poliovirus. Additional laboratory testing for infectious diseases conducted at the CDPH Viral and Rickettsial Disease Laboratory did not identify a causative agent to explain the observed clinical syndrome reported among the patients. To identify other cases of AFP with anterior myelitis and elucidate possible common etiologies, CDPH posted alerts in official communications for California local health departments during December 2012, July 2013, and February 2014. Reports of cases of neurologic illness received by CDPH were investigated throughout this period, and clinicians were encouraged to submit clinical samples for testing. A total of 23 cases of AFP with anterior myelitis of unknown etiology were identified. Epidemiologic and laboratory investigation did not identify poliovirus infection as a possible cause for the observed cases. No common etiology was identified to explain the reported cases, although EV-D68 was identified in upper respiratory tract specimens of two patients. EV infection, including poliovirus infection, should be considered in the differential diagnosis in cases of AFP with anterior myelitis and testing performed per CDC guidelines

    Rapid Influenza Antigen Test for Diagnosis of Pandemic (H1N1) 2009

    We compared the QuickVue Influenza test with PCR for diagnosing pandemic (H1N1) 2009 in 404 persons with influenza-like illness. Overall sensitivity, specificity, and positive and negative predictive values were 66%, 84%, 84%, and 64%, respectively. Rapid test results should be interpreted cautiously when pandemic (H1N1) 2009 virus is suspected

    The first reported case of California encephalitis in more than 50 years.

    Get PDF
    A recent case of California encephalitis, a rare mosquito-borne viral disease, represents only the fourth ever reported and the first since the initial three cases in 1945. This case was diagnosed retrospectively on the basis of a rise in antibody titer between acute- and convalescent-phase serum samples

    Prostate cancer and the impact on couples; a qualitative metasynthesis

    Get PDF
    Purpose: To review and interpret existing qualitative literature on the experiences of couples affected by prostate cancer (PCa). Methods: A metasynthesis was carried out which included a systematic search of seven databases between 2000 and 2016. A modified version of Noblit and Hare’s meta-ethnographic approach was used to synthesise qualitative study findings and inform overarching interpretations. Results: Thirty-seven studies focusing on the experiences of men with PCa and their partner dyad were included producing seven interconnected constructs. The construct accepting change vs seeking continuity reflects the range of ways individuals within the dyad and couples adjust to the diagnosis. Cultivating connection vs disengaging illustrates how couples seek to manage the impact of PCa and its treatment on their relationship, which may lead to a threatened identity, including sexual insecurities. Shielding me, you and us reflects the ways in which couples strive to protect themselves as individuals and/or each other from the impact of PCa. Being a partner and its challenges highlights the responsibilities partners assume and the impact of their supporting role. Yet, partners sometimes report feeling unsupported and side-lined both by the man they are caring for and by healthcare professionals. Couples often recognise the value of facing PCa together. Conclusions: PCa affects both members of the dyad as individuals, as well as the couple’s relationship. How best to support couples and how to overcome difficulties in expressing their concerns to one another requires further consideration. Healthcare professionals should endeavour to employ a couple-focused approach where appropriate

    Herpes simplex virus encephalitis is a trigger of brain autoimmunity

    In 5 prospectively diagnosed patients with relapsing post-herpes simplex encephalitis (HSE), N-methyl-D-aspartate receptor (NMDAR) antibodies were identified. Antibody synthesis started 1 to 4 weeks after HSE, preceding the neurological relapse. Three of 5 patients improved postimmunotherapy, 1 spontaneously, and 1 has started to improve. Two additional patients with NMDAR antibodies, 9 with unknown neuronal surface antibodies, and 1 with NMDAR and unknown antibodies, were identified during retrospective assessment of 34 HSE patients; the frequency of autoantibodies increased over time (serum, p=0.004; cerebrospinal fluid, p=0.04). The 3 retrospectively identified NMDAR antibody-positive patients also had evidence of relapsing post-HSE. Overall, these findings indicate that HSE triggers NMDAR antibodies and potentially other brain autoimmunity
