Magnetic resonance imaging of the quadriceps fat pad oedema pattern in relation to patellofemoral joint pathologies
Purpose: Quadriceps fat pad is located posterior to the quadriceps tendon. Increased signal intensity of this fat pad is seen on routine knee magnetic resonance imaging (MRI) examinations, but the exact mechanism and related pathologies are not clear. In this study we aimed to evaluate the relationship between MRI signal intensity and morphological features of quadriceps fat pad, as well as various pathologies of the patellofemoral joint. Material and methods: Sixty-one knees with quadriceps fat pad oedema out of 457 knee MRI examinations were included. Quadriceps fat pad signal intensity, dimensions, posterior indentation, and various parameters related to patellofemoral joint such as trochlear facet asymmetry, trochlear depth and sulcus angle, and the Insall-Salvati ratio were evaluated. Results: There was no statistically significant correlation between quadriceps fat pad oedema intensity and its dimensions, but it was significant when compared to posterior indentation. There was no correlation between fat pad oedema and each of the pathologies. However, there was a significant correlation between the presence of fat pad oedema and the presence of at least one of the pathologies related to patellofemoral joint. Conclusions: Quadriceps fat pad oedema detected in MRI examinations should warn the radiologist against the presence of various pathologies related to the patellofemoral joint
Termal Turizm Deneyiminin Müşteri Sadakatine Etkisinde Yaşam Kalitesi ve Müşteri Memnuniyetinin Aracı Rolü: Afyonkarahisar Örneği
Turizm farklı bir destinasyonu ziyaret edip orayı görmek ve orada zaman geçirmek üzerine kurulu
iken günümüzde yeni bir boyut daha kazanmış ve turistlerin orada yeni deneyimler yaşamasını da
içermiştir. Deneyim, turizm sektöründe eşsiz ve unutulmaz anlar yaşamak isteyen müşterilerin
işletmelerden beklediği güncel bir ihtiyaç ve istek olup termal turizmde de önem arz etmektedir. Bu
bağlamda işletmeler duyusal, duygusal, bilişsel, davranışsal ve ilişkisel deneyimlerden yararlanarak
müşterilerine deneyim sunabilmektedir. Bu araştırmanın amacı, termal turizm deneyimi konusuna
yönelik literatürdeki boşluğun doldurularak termal turizm deneyiminin müşteri sadakatine etkisini
incelemektir. Ayrıca yaşam kalitesi ve müşteri memnuniyetinin aracı rolünü değerlendirmektir. Belirli bir toplumdaki bireylerin genel durumunu değerlendirmesi, yaşam kalitesini vermektedir. Duygusal olarak mutlu olma; psikolojik olarak stressiz olma; fiziksel olarak sağlıklı olma; sosyal olarak
aile ve arkadaşlara sahip olma; nesnel değerlendirme olarak eğitim ve gelir düzeyleri; öznel değerlendirme olarak ise bireylerin yaşamları hakkındaki değerlendirmeleri yaşam kalitesini ortaya koymaktadır. Müşteri memnuniyeti ise işletmelerin faaliyetleri sonucu, müşterilerin yaşamına etki
eden deneyimler olup onların kaliteli zaman geçirmesini ifade etmektedir. Afyonkarahisar ilindeki
termal tesislerden turizm hizmeti almış bireylerden veriler elde edilerek AMOS paket programında
analizleri gerçekleştirilmiştir. Sonuç olarak, termal turizm deneyiminin müşteri sadakatine olumlu
etkisinin olduğu; aracı değişkenlerin de bu ilişkide kısmi aracı rolünün olduğu kabul edilmiştir
Sex-hormone-binding globulin early in pregnancy for the prediction of severe gestational diabetes mellitus and related complications
Aims: The aim of this study was to evaluate the predictive value of sex-hormone-binding globulin (SHBG) for
the diagnosis of gestational diabetes mellitus (GDM), and to clarify the association between SHBG levels and
GDM complications/medication requirements.
Material and Methods: Among the participants (n = 93) who provided blood samples between 13 and
16 weeks’ gestation, 30 cases subsequently developed GDM. Complications and medical interventions were
noted. The best cut-off point of SHBG and diagnostic performance were calculated.
Results: The mean age was 28.45 - 5.0 years. SHBG levels were lower in the GDM group (n = 30) when
compared with non-GDM (n = 63) cases (<0.01). Among the GDM women, SHBG was lower in the insulin
therapy group (n = 15) compared with medical nutritional therapy alone (n = 15) (P < 0.01). A good predictive
accuracy of SHBG was found for GDM requiring insulin therapy (area under the curve: 0.866, 95% confidence
interval: 0.773–0.959). An SHBG threshold for 97.47 nmol/L had a sensitivity of 80.0%, specificity 84.6%,
positive predictive value 50.0% and negative predictive value 95.7%. The calculated odds ratio for SHBG
< 97.47 nmol/L was 12.346 (95% confidence interval: 1.786–83.33).
Conclusions: SHBG is valuable for screening women early in pregnancy for GDM risk; however, a standard
assay for analyses and a threshold level of serum SHBG for a constant gestational week has to be determined
Antibacterial activity of bryophyte species against Paenibacillus larvae isolates
This study was performed to determine the antibacterial activity of methanol extracts of 23 bryophyte species against Paenibacillus larvae isolates that cause American foulbrood diseases in honeybee larvae. The honey and larva samples were collected from nine different locations of Rize in Turkey. A total of 22 gram-positive spore-forming bacteria were isolated from the larva and honey samples. According to the results of morphological, biochemical, and molecular (16S rRNA gene sequencing) tests, 10 isolates of the 22 gram-positive spore-forming bacteria were identified as P. larvae. A total of 10 bryophyte species (Polytrichum formasum,Polytrichum commune, Calliergonella cuspitada, Calliergonella lindbergi, Metzgeria conjugata, Isothecium alopecuroides, Syntrichia calcicola, Syntrichia intermedia, Tortella densa,and Grimmia alpestris) among 23 bryophytes showed good antimicrobial activity against P. larvae isolates according the results of agar-well diffusion method and minimal inhibition concentration experiments
The protective effects of different treatments on rat salivary glands after radiotherapy
WOS: 000387700400056PubMed ID: 27324888This study was aimed to evaluate the efficacy of treatment modalities for minimizing salivary gland damage caused by radiotherapy. Forty rats were divided into five groups. Group 1 had no irradiation or any treatment. Group 2 underwent only 15 Gy single dose radiotherapy. N-acetylcysteine, dexamethasone, hyperbaric oxygen treatment were given, respectively to the group 3, 4 and 5 for 5 days. 15 Gy single dose radiotherapy was applied to the group 3, 4 and 5 on the second day. Pyknosis, lysis, and vacuolization were examined in ductal cells and pyknosis, lysis, vacuolization, inflammation and collective duct damage in acinar cells. Dexamethasone and hyperbaric oxygen did not prove to have a positive effect on acinar and ductal cell. N-acetylcysteine-applied group had statistically significantly lower amount of damage. We determined that the decrease of ductal and acinar cell damage in parotid glands of N-acetylcysteine-applied rats was more distinct and statistically
A new index for the prediction of in-hospital mortality in patients with acute pulmonary embolism: The modified shock index
BACKGROUND: Pulmonary embolism severity index, its simplified version, and shock index have been used for risk stratification in acute pulmonary embolism. In this study, we proposed a modification in severity index and evaluated the correlates and prognostic value of modification in severity index in this setting. METHODS: The study group comprised retrospectively evaluated 181 patients with acute pulmonary embolism. Systematic workup including pulmonary embolism severity index, its simplified version, shock index, biomarkers, and echocardiographic and multidetector computed tomography assessments was performed in all patients. Moreover, we calculated modification in severity index by multiplying original shock index (heart rate/systolic blood pressure ratio) and a third component, 1/pulse oxymetric saturation (pSat O2%) ratio. The primary endpoint was defined as all-cause mortality and hemodynamic collapse during the hospital stay. RESULTS: On the basis of initial risk stratification, ultrasound-assisted thrombolysis, systemic tissue-type plasminogen activator, and unfractionated heparin therapies were utilized in 83 (45.9%), 37 (20.4%), and 61 (33.7%) patients, respectively. The primary end-point occurred in 13 (7.2%) patients. Receiver-operating curve analysis revealed that modification in severity index had the highest area under the curve of 0.739 (0.588-0.890, P =.002) compared with shock index, pulmonary embolism severity index, or its simplified version. The modification in severity index > 0.989 predicted primary endpoint with 73% sensitivity and 54% specificity. CONCLUSIONS: The modification in severity index seems to be a simple, quick, and compre-hensive risk assessment tool for bedside evaluation at initial stratification, in monitoring the clinical benefit from therapies, and decision-making for escalation to other reperfusion strategies in patients with acute pulmonary embolism. However, the prognostic value of modification in severity index needs to be validated with further studies
A novel composed index to evaluate the right ventricle free-wall adaptation against ventricular wall stress in acute pulmonary embolism
Background: Pulmonary embolism severity index and simplified pulmonary embolism severity index have been utilized in initial risk evaluation in patients with acute pulmonary embolism. However, these models do not include any imaging measure of right ventricle function. In this study, we proposed a novel index and aimed to evaluate the clinical impact. Methods: Our study population comprised retrospectively evaluated 502 patients with acute pulmonary embolism managed with different treatment modalities. Echocardiographic and computed tomographic pulmonary angiography evaluations were performed at admission to the emergency room within maximally 30 minutes. The formula of our index was as follows: (right ventricle diameter × systolic pulmonary arterial pressure-echo)/(right ventricle free-wall diameter × tricuspid annular plane systolic excursion). Results: This index value showed significant correlations to clinical and hemodynamic severity measures. Only pulmonary embolism severity index, but not our index value, independently predicted in-hospital mortality. However, an index value higher than 17.8 predicted the long-term mortality with a sensitivity of 70% and specificity of 40% (areas under the curve = 0.652, 95% CI, 0.557-0.747, P = .001). According to the adjusted variable plot, the risk of long-term mortality increased until an index level of 30 but remained unchanged thereafter. The cumulative hazard curve also showed a higher mortality with high-index value versus low-index value. Conclusions: Our index composed from measures of computed tomographic pulmonary angiography and transthoracic echocardiography may provide important insights regarding the adaptation status of right ventricle against pressure/wall stress in acute pulmonary embolism, and a higher value seems to be associated with severity of the clinical and hemodynamic status and long-term mortality but not with in-hospital mortality. However, the pulmonary embolism severity index remained as the only independent predictor for in-hospital mortality
Validity and reliability of the assessment tool for Asthma (ATA) questionnaire: the ATA study
OBJECTIVES: A multicenter trial was designed to validate the “Assessment Tools for Asthma (ATA)” questionnaire, a newly developed questionnaire, which evaluates both asthma control and risk factors associated with asthma control with a single instrument. MATERIALS AND METHODS: This cross-sectional study involved 810 cases from 14 clinics in 9 Turkish cities. The ATA questionnaire and Asthma Control Test (ACT) were administered. The Visual Analog Scale (VAS) was used to evaluate the control status of 100 randomized cases. ATA is an eight-item physician-administered questionnaire. It comprises the following two sections-ATA1, assesses symptomatic control criteria, and the remaining section, queries the flre-up of asthma, control of comorbidities, treatment adherence, and inhaler technique. RESULTS: The mean scores for ATA1, ATA total, VAS, and ACT were 24.7±14.8, 53.8±19, 7.1±3, and 18.8±5.5, respectively. According to the ATA questionnaire, among all patients, 34.3% had controlled, 18.8% had partly controlled, and 46.9% had uncontrolled asthma. Furthermore, 16.6% patients had flre-ups between visits, 96.4% patients had uncontrolled comorbidity, 17% patients had irregular asthma treatment, and only 8.4% patients used the incorrect inhaler technique. The ATA questionnaire showed internal consistency (Cronbach’s alpha coeffiient=0.683). ACT, ATA1, and two specialists’ evaluations using VAS correlated strongly with the ATA total scores (Spearman correlation coeffiient (r) values: 0.776, 0.783, and 0.909, respectively; p-values: p<0.001, p<0.001, and p<0.001, respectively). According to Receiver Operating Characteristic analysis, the cut-off value of ATA was 50 (sensitivity=84.4%, specifiity=82.40%). CONCLUSION: The validated ATA questionnaire may be a practical tool for physicians in asthma management
Evaluation of patients with fibrotic interstitial lung disease: Preliminary results from the Turk-UIP study
OBJECTIVE: Differential diagnosis of idiopathic pulmonary fibrosis (IPF) is important among fibrotic interstitial lung diseases (ILD). This study aimed to evaluate the rate of IPF in patients with fibrotic ILD and to determine the clinical-laboratory features of patients with and without IPF that would provide the differential diagnosis of IPF.
MATERIAL AND METHODS: The study included the patients with the usual interstitial pneumonia (UIP) pattern or possible UIP pattern on thorax high-resolution computed tomography, and/or UIP pattern, probable UIP or possible UIP pattern at lung biopsy according to the 2011 ATS/ERSARS/ALAT guidelines. Demographics and clinical and radiological data of the patients were recorded. All data recorded by researchers was evaluated by radiology and the clinical decision board.
RESULTS: A total of 336 patients (253 men, 83 women, age 65.8 +/- 9.0 years) were evaluated. Of the patients with sufficient data for diag-nosis (n=300), the diagnosis was IPF in 121 (40.3%), unclassified idiopathic interstitial pneumonia in 50 (16.7%), combined pulmonary fibrosis and emphysema (CPFE) in 40 (13.3%), and lung involvement of connective tissue disease (CTD) in 16 (5.3%). When 29 patients with definite IPF features were added to the patients with CPFE, the total number of IPF patients reached 150 (50%). Rate of male sex (p<0.001), smoking history (p<0.001), and the presence of clubbing (p=0.001) were significantly high in patients with IPE None of the women <50 years and none of the men <50 years of age without a smoking history were diagnosed with IPE Presence of at least 1 of the symptoms suggestive of CTD, erythrocyte sedimentation rate (ESR), and antinuclear antibody (FANA) positivity rates were significantly higher in the non-IPF group (p<0.001, p=0.029, p=0.009, respectively).
CONCLUSION: The rate of IPF among patients with fibrotic ILD was 50%. In the differential diagnosis of IPF, sex, smoking habits, and the presence of clubbing are important. The presence of symptoms related to CTD, ESR elevation, and EANA positivity reduce the likelihood of IPF

The genetic history of the Southern Arc: a bridge between West Asia and Europe
By sequencing 727 ancient individuals from the Southern Arc (Anatolia and its neighbors in Southeastern Europe and West Asia) over 10,000 years, we contextualize its Chalcolithic period and Bronze Age (about 5000 to 1000 BCE), when extensive gene flow entangled it with the Eurasian steppe. Two streams of migration transmitted Caucasus and Anatolian/Levantine ancestry northward, and the Yamnaya pastoralists, formed on the steppe, then spread southward into the Balkans and across the Caucasus into Armenia, where they left numerous patrilineal descendants. Anatolia was transformed by intra–West Asian gene flow, with negligible impact of the later Yamnaya migrations. This contrasts with all other regions where Indo-European languages were spoken, suggesting that the homeland of the Indo-Anatolian language family was in West Asia, with only secondary dispersals of non-Anatolian Indo-Europeans from the steppe
