Repeated Rapid Active Sampling Surveys Demonstrated a Rapidly Changing Zika Seroprevalence among Children in a Rural Dengue-endemic Region in Southwest Guatemala during the Zika Epidemic (2015-2016).

ABSTRACT: Although Central America is largely dengue virus (DENV)-endemic, the 2015-2016 Zika virus (ZIKV) pandemic brought new urgency to develop surveillance approaches capable of characterizing the rapidly changing disease burden in resource-limited settings. We conducted a pediatric DENV surveillance study in rural Guatemala, including serial cross-sectional surveys from April through September 2015 (Survey 1), in October-November 2015 (Survey 2), and January-February 2016 (Survey 3). Serum underwent DENV IgM MAC ELISA and polymerase chain reaction testing. Using banked specimens from Surveys 2 and 3, we expanded testing to include DENV 1-4 and ZIKV microneutralization (MN50), DENV NS1 IgG ELISA, and ZIKV anti-NS1 antibody Blockage of Binding (BoB) ELISA testing. Demographic risk factors for ZIKV BoB positivity were explored using multivariable generalized linear regression models. Of Survey 2 and 3 samples available (N = 382), DENV seroprevalence slightly increased (+1%-10% depending on the assay) during the surveillance period and increased with age. In contrast, ZIKV seroprevalence consistently increased over the 3-month period, including from 6% to 34% (P < 0.0001) and 10%-37% (P < 0.0001) using the MN50 ≥100 and BoB ELISA assays, respectively. Independent risk factors for ZIKV seropositivity included older age (prevalence ratio (PR)/year = 1.12, 95% confidence interval (CI) = 1.07-1.17) and primary caregiver literacy (PR = 2.80, CI = 1.30-6.06). Rapid active surveillance (RAS) surveys demonstrated a nearly 30% increase in ZIKV prevalence and a slight (≤ 10%) increase in DENV seroprevalence from October to November 2015 to January to February 2016 in rural southwest Guatemala, regardless of serologic assay used. RAS surveys may be a useful "off-the-shelf" tool to characterize arboviruses and other emerging pathogens rapidly in resource-limited settings.

Project description:IntroductionAn overview of the requirements for the head of a surgical department in Germany should be given.Materials and methodsA retrospective literature research on surgical professional policy publications of the last 10 years in Germany was conducted.ResultsSurveys show that commercial influences on medical decisions in German hospitals have today become an everyday, predominantly negative, actuality. Nevertheless, in one survey, 82.9% of surgical chief physicians reported being very satisfied with their profession, compared with 61.5% of senior physicians and only 43.4% of hospital specialists. Here, the chief physician is challenged. Only 70% of those surveyed stated that they could rely on their direct superiors when difficulties arose at work, and only 34.1% regarded feedback on the quality of their work as sufficient. The high distress rate in surgery (58.2% for all respondents) has led to a lack in desirability and is reflected in a shortage of qualified applicants for resident positions. In various position papers, surgical residents (only 35% describe their working conditions as good) demand improved working conditions. Chief physicians are being asked to facilitate a suitable work-life balance with regular working hours and a corporate culture with participative management and collegial cooperation. Appreciation of employee performance must also be expressed. An essential factor contributing to dissatisfaction is that residents fill a large part of their daily working hours with non-physician tasks. In surveys, 70% of respondents stated that they spend up to ≥3 h a day on documentation and secretarial work.DiscussionThe chief physician is expected to relieve his medical staff by employing non-physician assistants to take care of non-physician tasks. Transparent and clearly structured training to achieve specialist status is essential. It has been shown that a balanced work-life balance can be achieved for surgeons. Family and career can be reconciled in appropriately organized departments by making use of part-time and shift models that exclude 24-h shifts and making working hours more flexible.
