Clinical Characteristics and Outcome of COVID-19 in Turkish Hematological Malignancy Patients
No full textObjective: Patients with solid malignancies are more vulnerable
to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)
infection than the healthy population. The outcome of SARS-CoV-2
infection in highly immunosuppressed populations, such as in patients
with hematological malignancies, is a point of interest. We aimed to
analyze the symptoms, complications, intensive care unit admissions,
and mortality rates of patients with hematological malignancies
infected with SARS-CoV-2 in Turkey.
Materials and Methods: In this multicenter study, we included
340 adult and pediatric patients diagnosed with SARS-CoV-2 from
March to November 2020. Diagnosis and status of primary disease,
treatment schedules for hematological malignancies, time from last
treatment, life expectancy related to the hematological disease, and
comorbidities were recorded, together with data regarding symptoms,
treatment, and outcome of SARS-CoV-2 infection.
Results: Forty four patients were asymptomatic at diagnosis of SARS CoV-2 infection. Among symptomatic patients, fever, cough, and
dyspnea were observed in 62.6%, 48.8%, and 41.8%, respectively. Sixty nine (20%) patients had mild SARS-CoV-2 disease, whereas moderate,
severe, and critical disease was reported in 101 (29%), 71 (20%), and 55
(16%) patients, respectively. Of the entire cohort, 251 (73.8%) patients
were hospitalized for SARS-CoV-2. Mortality related to SARS-CoV-2
infection was 26.5% in the entire cohort; this comprised 4.4% of those
patients with mild disease, 12.4% of those with moderate disease,
and 83% of those with severe or critical disease. Active hematological
disease, lower life expectancy related to primary hematological disease,
neutropenia at diagnosis of SARS-CoV-2, ICU admission, and first-line
therapy used for coronavirus disease-2019 treatment were found to be
related to higher mortality rates. Treatments with hydroxychloroquine
alone or in combination with azithromycin were associated with a
higher rate of mortality in comparison to favipiravir use.
Conclusion: Patients with hematological malignancy infected with
SARS-CoV-2 have an increased risk of severe disease and mortality
Fatty acid composition of root and shoot samples of some Astragalus L. (Fabaceae) taxa growing in the east and southeast of Turkey.
Full text linkThe fatty acid compositions of root and shoot samples of some Astragalus L. (Fabaceae) taxa [A. gossypinus Fisch., A.
amblolepis Fisch., A. edmondi (Kuntze) Sheld., A. tigridis Boiss., A. aleppicus Boiss., A. suberosus Banks & Sol. subsp. suberosus Banks &
Sol., A. gummifer Labill., A. diphtherites Fenzl var. diphtherites Fenzl, and A. gymnalopecias Rech.f.] growing in the east and southeast
of Turkey were determined by gas chromatography. Astragalus species contained palmitic (C 16:0) (20.13%–53.8%), linoleic (C 18:2ω6) (13.25%–41.06%), oleic (C 18:1ω-9) (5.78%–25.7%), linolenic (C 18:3ω-3) (6.1%–22.89%), and stearic acid (C 18:0) (5.16%–13.1%)
in the roots and linolenic (8.9%–51.42%), palmitic (20.16%–44.88%), linoleic (7.34%–27.57%), oleic (2.45%–17.91%), and stearic acid
(4.28%–8.31%) in the shoots as major components. In this study the fatty acid composition of Astragalus species showed uniform fatty
acid patterns. Palmitic and stearic acids were the major saturated and linoleic and linolenic acids were the major unsaturated fatty acids
in the roots and shoots
Readability and understandability of andrology questionnaires
No full textObjective: Medical questionnaires, which enable collection, comparison and analysis of appropriate data as a means of written communication between a patient and a doctor, must be easily readable, and understandable. Here, we measure the readability and understandability of questionnaires used in andrology and examine the relationship between the educational status of the patients and the understandability of the forms. Material and methods: Seven questionnaires used to diagnose andological diseases were selected from the European Association of Urology guidelines. The number of syllables per word, the number of words in a sentence, and the average word and sentence lengths were calculated for each Turkish validated form. Readability scores were calculated, and closet tests were used to measure the understandability of the texts. Results: Three hundred and twenty-seven male volunteers participated in the study. Two hundred and sixteen of the participants (66%) had a high school or college education. The readability level of the seven forms was determined to be ''Difficult'' or ''Very Difficult,'' and at least a high school education level was required to understand the forms. As education level and monthly income increased, the understandability of the forms increased; as the readability of the forms became more difficult, their understandability decreased (p0.001). Conclusion: The readability levels of questionnaires used in andrology are well above the reading level of Turkey. Health providers can help patients to fill out forms to increase doctor-patient communication
Effects of degraded sensor resolution upon passive microwave precipitation retrievals of tropical rainfall
No full textBased on the fundamental relationship involving the interaction of microwave radiation with precipitation,
microwave-based satellite precipitation estimates hold the most promise for quantitative rain estimation from
space. At present, the low-resolution channels onboard the DMSP Special Sensor Microwave Imager (SSM/I)
are sampled with a spatial resolution several times larger than the scale at which rainfall is generated in typical
convective rainbands. Aircraft-based instruments can provide views of the detailed microwave radiometric
characteristics of precipitating clouds.
In this manuscript, the authors present coincident finescale (1–3-km resolution) collocated aircraft radiometric
and aircraft precipitation radar measurements collected during the 1993 Tropical Ocean Global Atmosphere
Coupled Ocean–Atmosphere Response Experiment in the western Pacific Ocean. By intentionally degrading the
resolution of the aircraft datasets from their native resolution to that of current and future spaceborne sensors,
the impact of sensor resolution upon a combined radiometer–radar vertical profiling rain-retrieval algorithm
(developed and utilized for the Precipitation Intercomparison Program 2) was examined. Retrieved values of
the columnar graupel content were more influenced by the addition of the radar profile than was the columnar
rain content. The retrieved values of columnar graupel were also significantly smaller than previously published
results for land-based rainfall. The results show that the general trend of the rain structure is maintained but
finescale details are lost once the observations are reduced to resolutions of 15 km
Supply Trends in Slovenian Agriculture under Transition to the Market
No full textThe article examines production and price trends in Slovenian agriculture over the period between 1961-1995. Own and cross-price elasticities for six principal agricultural products are derived: in the crop sector wheat, maize and potatoes in the livestock sector for milk, beef and pork. During the period as a whole, total production more than doubled for meat and maize production; somewhat less output growth was registered for wheat and milk production, whereas potato production decreased, reaching about 50 percent of its 1961 production level
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
