Nasopharyngeal pneumococcal carriage in healthy Turkish children after 13-valent conjugated pneumococcal vaccine implementation in the national immunization program.
No full textIn Turkey, pneumococcal conjugated vaccine (PCV) was introduced to the national immunization program as PCV7 in 2008, and was replaced with PCV13 in 2011. The aims of this study were to investigate the effects of PCV13 on nasopharyngeal pneumococcal carriage (NPC) by determining the serotype distribution, and to identify risk factors for carriage, in healthy Turkish children
Multicenter Hospital-Based Prospective Surveillance Study of Bacterial Agents Causing Meningitis and Seroprevalence of Different Serogroups of Neisseria meningitidis, Haemophilus influenzae Type b, and Streptococcus pneumoniae during 2015 to 2018 in Turkey
No full textThe etiology of bacterial meningitis in Turkey changed after the
implementation of conjugated vaccines against Streptococcus pneumoniae
and Haemophilus influenzae type b (Hib) in the Turkish National
Immunization Program (NIP). Administration of Hib vaccine and PCV-7
(7-valent pneumococcal conjugate vaccine) was implemented in NIP in 2006
and 2009, respectively. In 2011, PCV-7 was replaced with PCV-13.
Meningococcal vaccines have not yet been included in Turkish NIP. This
prospective study comprised 27 hospitals located in seven regions of
Turkey and represented 45\% of the population. Children aged between 1
month and 18 years who were hospitalized with suspected meningitis were
included. Cerebrospinal fluid (CSF) samples were collected, and
bacterial identification was made according to the multiplex PCR assay
results. During the study period, 994 children were hospitalized for
suspected meningitis, and Hib (n = 3, 2.4\%), S. pneumoniae (n = 33,
26.4\%), and Neisseria meningitidis (n = 89, 71\%) were detected in 125
samples. The most common meningococcal serogroup was MenB. Serogroup W
comprised 13.9\% (n = 5) and 7.5\% (n = 4) of the meningococci in 2015
to 2016 and 2017 to 2018, respectively. Serogroup C was not detected.
There were four deaths in the study; one was a pneumococcus case, and
the others were serogroup B meningococcus cases. The epidemiology of
meningococcal diseases has varied over time in Turkey. Differing from
the previous surveillance periods, MenB was the most common serogroup in
the 2015-to-2018 period. Meningococcal epidemiology is so dynamic that,
for vaccination policies, close monitoring is crucial.
IMPORTANCE Acute bacterial meningitis (ABM) is one of the most common
life-threatening infections in children. The incidence and prevalence of
ABM vary both geographically and temporally; therefore, surveillance
systems are necessary to determine the accurate burden of ABM. The
Turkish Meningitis Surveillance Group has been performing a
hospital-based meningitis surveillance study since 2005 across several
regions in Turkey. Meningococcus was the major ABM-causing agent during
the 2015-to-2018 period, during which MenB was the dominant serogroup
Succinivibrionaceae is dominant family in fecal microbiota of Behcet's Syndrome patients with uveitis
No full textBehcet's Syndrome (BS) is a multisystem vasculitis with various clinical
manifestations. Pathogenesis is unclear, but studies have shown genetic
factors, innate immunity and autoinflammation to have an important role
in the disease course. Diversity in the microbial community of gut
microbiota may significantly contribute to the activation of the innate
immune system. The clinical features of BS present themselves in
clusters and each cluster may be a consequence of different disease
mechanisms. For this reason we aimed to investigate the gut microbiota
of BS patients with uveitis. In addition to healthy controls, we have
aimed to compare the gut microbiota of BS with that of Familial
Mediterranean Fever (FMF) and Crohn's Disease (CD) as both diseases have
innate and autoinflammatory features in their pathogenesis. Seven
patients with BS, 12 patients with FMF, 9 patients with CD and 16
healthy controls (HC) were included in the study. Total genomic DNAs
were isolated from fecal samples of the patients. Partial 16S rRNA gene
was sequenced using the PGM Ion Torrent (Thermo Fisher Scientific,
Waltham, MA, USA) for microbiota analysis. Statistical analysis showed
that significant differences were detected on the microbial community of
four groups. Succinivibrionaceae is dominant and the signature family,
whereas Bacteroides was absent in BS patients
Research Trends in Mobile Learning
No full textA total of 1023 selected articles published in 2016-2019 related to
mobile learning were examined and classified according to the categories
in this research: 4o\% of these articles used quantitative approaches,
18\% of them used mixed, and 13\% of them were literature reviews. The
published studies were analyzed according to research model, sample
size, sample level, learning fields, subject-area classification, data
collection tool, data analysis technique, dependent variable,
independent variable, mobile device, number of authors, and publication
year. The findings were analyzed and interpreted as a percentage and
frequency. This research will be useful for reviewing current research
trends related to mobile learning studies, indicating potential research
on the topics, and revealing the needs of the field
Design and implementation of a 22 kW full-bridge push-pull series partial power converter for stationary battery energy storage system with battery charger
No full textA wide variety of AC/DC power converter topologies have been developed
in order to improve the system efficiency, input power factor and system
redundancy for stationary battery energy storage systems. Due to the
nature of high-power batteries, there is a big voltage difference
between battery terminals from the end of discharge to the high charge
value. To prevent unregulated battery voltages from harming the system
loads, several techniques are used in the industry. A well-known old
technique named as diode dropper is simple but suffers from low
efficiency. Using a DC-DC converter is more advantageous, although it
increases the cost. In this paper, the use of partial power processing
converters which attract interest these days has been proposed as an
alternative. The proposed full bridge/push-pull series connected partial
power converter has a slight modification compared to the classical one
presented in the literature. A system with 22 kW power rating was
designed and tested. In order to compare the results, a two-switch
buck-boost converter was also designed and tested for the same
conditions. The results show that the proposed converter is superior to
both the two-switch buck-boost converter and other topologies in terms
of efficiency and response speed. Efficiencies of 97\%-99\% have been
attained with the proposed converter
