Importance of Strategic Flexibility on the Knowledge and Innovation Relationship: An Emerging Market Study
This study seeks to explore the impact of strategic flexibility on the relationship between knowledge management and innovation performance. In order to achieve this, a self-administrated questionnaire was conducted on a sample of 187 firms from different industries in Turkey and a couple of hypotheses were tested. The two way interaction of knowledge management and strategic flexibility was associated more strongly with innovation performance than the direct and single relationship of knowledge management and innovation performance. Therefore, it was found that the effectiveness of knowledge management leading to innovation performance is contingent on strategic flexibility
THE PREDICTORS OF MORTALITY IN IPF - DOES EMPHYSEMA CHANGE THE PROGNOSIS?
Background: Combined idiopathic pulmonary fibrosis (IPF) and emphysema (CPFE) has been reported to be more common in male smokers. A number of studies comparing CPFE patients with fibrosis-only patients have reported a similar prognosis while others have reported a significantly shorter survival. Objectives: In present study, we aimed to compare baseline characteristics of patients with IPF according to emphysema presence. We asssessed the prognostic value of emphysema along with each other parameter. Methods: We retrospectively reviewed the clinical, baseline radiological, laboratory and physiological parameters of 92 patients who were diagnosed with IPF. The patients were divided into two groups: those without emphysema (Group 1) and with emphysema (Group 2). All-cause mortality was recorded, and the impact of the variables on survival was evaluated. Results: Emphysema was recorded in 23 patients, all of whom were male. While ever-smoker rate was higher in Group 2 laboratory and physiologic parameters were similar. Radiologically, the presence of honeycombing, ground glass opacity, the extension and symmetry of involvement did not differ between the Groups. The median survival time was 29 +/- 4 months. Patients in Group 1 and 2 had a median survival of 34 and 9 months, respectively. In univariate analysis; radiological presence of emphysema and honeycombing, male gender, lower baseline levels of albumin and oxygen saturation, forced vital capacity and carbon monoxide diffusing capacity were detected as predictors of mortality. Conclusion: In present study, IPF with emphysema was more common in male smokers. When emphysema accompanies IPF, life expectancy is remarkably worse, but not independently so
Should patients with risk factors be tested for hypersensitivity to contrast media: a prospective study
Previous hypersensitivity reactions to contrast media (CM), atopy, atopic disease, drug allergy, and age (20-29 or > 55) are risk factors for CM hypersensitivity reactions. Our aim was to evaluate whether these risk factors should prompt skin testing for diagnosing CM allergy
A Rare Case of Progressive Dyspnea and Bilateral Lung Infiltration in a Young Male
Pulmonary lymphangitic carcinomatosis (PLC) is defined as infiltration of the lymphatic vessels and perilymphatic connective tissue with tumor cells, which is secondary to malignancy. Therefore, it rarely appears as an initial finding preceding a diagnosis of malignancy. A 30-year-old male patient was hospitalized in our clinic with a pre-diagnosis of interstitial lung disease owing to the complaints of dry cough, progressive dyspnea, and acute respiratory insufficiency. He was diagnosed with signet ring cell carcinoma, which is a histologic subtype of adenocarcinoma, via gastroscopy, and lung involvement was consistent with PLC. Regardless of the patient age, PLC should be considered in differential diagnoses of progressive dyspnea, acute respiratory failure, and widespread interstitial lung involvement
How much are we aware of the increase in accompanying comorbidities in sarcoidosis?
OBJECTIVE: Sarcoidosis is a multisystem chronic disease characterized by granulomatous inflammation. It is reported that the frequency of other inflammatory and malignant diseases increases. The primary objective of the study is to determine the types of comorbid diseases and their frequency, and whether the risk of malignancies and autoimmune diseases such as rheumatoid arthritis and thyroid increases. The secondary objective is to identify the factors related to the comorbidities frequently detected.
METHODS: The files of 694 patients who had the diagnosis of sarcoidosis between1998-2016 were evaluated. The frequency of comorbid diseases recorded was compared to the data of our country.
RESULTS: Among the patients, 487 (70%) were female, and the mean age at diagnosis was 42.9 ± 11.8 (18-87). In 490 patients (70%) at least one comorbidity was detected. The most frequently detected comorbidities were systemic hypertension (22%), hepatosteatosis (16.9%), diabetes mellitus (16.4%), thyroid diseases (13.1%), and asthma (12%). Malignancy was found in a ratio of 4.0%, rheumatoid arthritis in 2.2%. The comparison to the frequencies across the country showed that the prevalence of diabetes mellitus, thyroid diseases, asthma, malignancy, and rheumatoid arthritis was higher. Diabetes, thyroid diseases, asthma were more frequent in women. The mean age of patients in which diabetes, thyroid diseases, asthma, rheumatoid arthritis or malignancy was detected as a comorbidity was higher than those without comorbidities.
CONCLUSION: Comorbidities frequently occur among sarcoidosis patients, and the frequency of diabetes mellitus, thyroid diseases, asthma, malignancy, and rheumatoid arthritis is higher than the data of the country
Hyponatremia prolongs hospital stay and hypernatremia better predicts mortality than hyponatremia in hospitalized patients with community-acquired pneumonia
Introduction: Dysnatremia is reported to have a prognostic effect in various diseases. A limited number of studies have been published on dysnatremia-related parameters and clinical outcome in patients with pneumonia. The aim of the study is to analyze the factors related to baseline dysnatremia and to evaluate the clinical outcome of dysnatremia on hospital stay, 30-day and 1-year mortality in hospitalized patients with community-acquired pneumonia (CAP)
Evaluation of the results of MOTAKK hepatitis C virus RNA genotyping and hepatitis delta virus external quality assessment programs during 2015-2016
Background/Aims: To evaluate the HCV RNA genotyping and HDV RNA tests
that are performed in molecular microbiology laboratories in Turkey as
part of a national external quality assessment programme, MOTAKK
(Molekuler Tanida Kalite Kontrol) (English translation: Quality control
in molecular diagnostics).
Materials and Methods: Plasmas having different HCV RNA genotypes were
used to prepare HCV genotype control sera. The HDV RNA main stock was
prepared from patients with chronic delta hepatitis who had a
significant amount of viral load detected, as per the WHO reference
materials on viral load studies that were compiled for the purpose of
developing HDV RNA control sera. Samples with different viral loads were
prepared from this main stock by dilution. The prepared controls were
delivered to the registered laboratories. The laboratories carried out
the relevant tests and entered their results via the MOTAKK web page.
External quality assessment (EQA) reports of the participants were
uploaded to the website as well.
Results: In total, there were 23 participating laboratories, out of
which 20 exclusively performed HCV genotyping, and 15 and 16 only
performed HDV RNA in 2015 and 2016, respectively. The success rate of
the results of the HCV genotype was 56-96\% in 2015 and 30-95\% in 2016.
The tube with a 30\% success rate had a recombinant type of HCV,
therefore, it could not be detected in most of the laboratories. The HDV
RNA results were evaluated qualitatively. Accordingly, HDV RNA detection
rates of participant laboratories were 71-100\% in 2015 and 50-100\% in
2016.
Conclusion: This study was the first national external quality control
program in Turkey regarding HCV RNA genotyping and HDV RNA in the field
of molecular microbiology, and it was implemented successfully
