Acceptability and effectiveness of a novel cycling training on the parkinsonian motor and psychiatric symptoms in individuals with schizophrenia: A pilot study

Background Recent evidence suggests that high-speed, low-resistance stationary cycling training (termed as speedwork) alleviates motor symptoms in people with Parkinson’s disease. Similar motor symptoms commonly exist in people with schizophrenia (Sz); however, they were neglected in the previous literature. Objectives Our objective was to evaluate if speedwork could also be used as a strategy to improve parkinsonian motor symptoms in Sz. We aimed 1) to evaluate the adherence and acceptability of speedwork in Sz, 2) to assess test-retest reliability of the motor assessments that are novel to Sz research, 3) to evaluate the effectiveness of speedwork in improving parkinsonian motor, and 4) psychiatric symptoms in Sz. Methods Ten Sz outpatients with concurrent parkinsonian motor symptoms completed 12 sessions (2 sessions/week) of speedwork training. Participants were evaluated on motor functioning and psychiatric symptom severity twice before (double baseline) and twice after (post-completion and 6-wk follow-up) the speedwork training. Results The adherence to speedwork was high (92 %) and the results of exercise acceptability questionnaire indicate participants found various domains of exercise highly acceptable (overall average 4.49/5). There were improvements in various domains of motor symptoms including, walking speed, functional mobility, static and dynamic balance, and upper extremity motor function after the completion of training (all p \u3c 0.025), with many of these improvements remaining at the 6-wk follow-up. Moreover, there was evidence for improvement in positive psychotic symptoms after the completion of speedwork (p \u3c 0.025). Conclusions Speedwork training could be an acceptable and effective strategy to improve motor and psychiatric symptoms in Sz

STRATEJİK KARAR VERME SÜRECİNİ ETKİLEYEN FAKTÖRLER: ULUSLARARASI TAŞIMACILIK SEKTÖRÜ İŞLETMELERİNDE BİR ARAŞTIRMA

Stratejik karar verme, rekabette sadece mevcut pozisyonu koruma değil, gelecek pozisyonu yaratma potansiyeli ile birlikte düşünülür. Ancak gelecek pozisyonu yaratmak zorlu bir süreç içerir, ya da stratejik karar verme sürecinin kuramsal ve uygulama olarak ifade edilmesi kolay değildir. Bunun en başat nedeni, süreci etkileyen faktörlerin çokluğu, çeşitliliği ve niteliğidir. Bu amaçla makalede, stratejik karar verme sürecini etkileyen faktörler üzerine odaklaşılmış; literatürde Dean ve Sharfman ile Baum ve Wllay’in öngördüğü belirleyici 4 faktöre (rasyonellik, kararın önem derecesi, çatışma ve belirsizlik) bağlı, Mersin ili merkezli uluslararası taşımacılık sektörü işletmelerinde araştırılması ve elde edilen bulguların yorumlanması hedeflenmiştir

Thyroid papillary carcinoma presenting with femoral neck metastasis: a case report

Thyroid carcinoma is relatively uncommon, accounting for 2% of all cancers. Although they usually present as a neck lump, occasionally they may be presented with a distant metastasis. In this study, a 65 year-old woman was referred to our clinic with a pain on her left hip at both rest and walking. A lytic area at the inferior femoral neck was found with plain radiography. To clarify the characteristics of the lesion, left hip magnetic resonance imaging (MRI) had been performed displaying 3×5 cm hyperintense lesion extending from medial part of the left femoral neck to the left femoral head. Laboratory findings were normal. An open biopsy had then been performed from the left femoral neck with a suspicion of a metastatic tumor. After Immunohistochemical assesment diagnosis was consistent with metastatic thyroid papillary cancer. Proximal femoral resection with clear margins were achieved by proximal femur tumor endoprosthesis.  In conclusion, papillary thyroid cancer have an excellent prognosis and doesn’t tend to metastese. But rarely, as seen in our case it can even present with syptoms of metastasic disease. Management strategy is the same as other solitary bone metastasis. Papillary thyroid cancer must be kept in mind as a differential diagnosis in solitary bone metatasis

The relationship between functional capacity and ultrasonic tissue characterization in patients with idiopathic dilated cardiomyopathy

Background: Ultrasonic tissue characterization (UTC) has been widely used to investigate left ventricular (LV) dysfunction in various cardiac disorders. The aim of this study was to investigate the correlation between functional capacity and UTC in patients with idiopathic dilated cardiomyopathy (IDCM).Methods and Results: Treadmill test according to modified-Bruce protocol was performed in 48 patients with IDCM to assess their functional capacity. Baseline clinical and echocardiographic variables were obtained and UTC was performed on images obtained from septum and posterior wall (PW). Cyclic variation (CV) index of mean gray level (MGL) was calculated according to the formula: [(MGLdiastole − MGLsystole) ÷ MGLdiastole] × 100.PW and septum CV indices were correlated with exercise duration (r = 0.63, p = 0.001 and r = 0.67, p = 0.0001, respectively) and “MET” level (r = 0.80, p = 0.0001 and r = 0.83,p = 0.0001, respectively). The ROC curve analysis revealed that the PW CV index was a strong indicator of good exercise capacity (> 8 METs) with an AUC of 0.97 (95% CI0.90–1.0), as the interventricular septum (IVS) CV index (AUC = 0.97, 95% CI 0.89–1.0). Sensitivity, specificity, positive predictive value, and negative predictive value to identify good exercise capacity for IVS CV index were 90%, 88%, 82%, and 94%, respectively and for the PW CV index, 90%, 88%, 82%, and 94%, respectively.Conclusions: In this particular study, we found out that in patients with severe LV dysfunction good exercise capacity was related to septum and PW CV indices measured by UTC, and these indices may be used as an indirect prognostic marker in heart failure

Rare Birth Defects in Pregnancies of Women with Pregestational Diabetes: Absent Radius

Diabetes mellitus (DM) is an important disease that negatively affects fetal development and women with pregestational diabetes have an increased risk for adverse pregnancy outcomes, including a markedly increased risk for birth defects. In this report, a newborn with absent radius associated with pregestational diabetes was presented. A male newborn was born at 40th gestational week from a 20-year-old mother by cesarean section. The patient had shortness in the limbs, hypoplastic right thumb and flexion contracture at his right hand besides respiratory distress.To our knowledge, with this case report, we would like to share the second case of diabetic mother's infant with absent radius in the literature

A simplified acute kidney injury predictor following transcatheter aortic valve implantation: ACEF score

Background: Transcatheter aortic valve implantation (TAVI) is an effective, less invasive treatment alternative for symptomatic severe aortic stenosis (AS). Acute kidney injury (AKI) following TAVI is a common complication and is associated with worse outcomes. The age, creatinine, ejection fraction (ACEF) score is a simple scoring method, including only three parameters: age, creatinine, and ejection fraction (EF). The score was well established in predicting AKI after coronary interventions.Aims: We aimed to evaluate whether this simple scoring method, ACEF, may predict a development of AKI in patients who underwent TAVI.Methods: A total of 173 consecutive patients with symptomatic severe AS who underwent TAVI were included retrospectively. The primary endpoint of the study was the development of AKI. Study population was divided into two groups according to the presence of AKI. The ACEF score was calculated with the formula: age/EF + 1 (if baseline creatinine >2 mg/dl).Results: Twenty-nine patients developed AKI. The median (interquartile range) ACEF score was 1.36 (1.20–1.58). The ACEF score was found to be an independent predictor of AKI (P <0.001). The ACEF score ≥1.36 predicted AKI development with a sensitivity of 96.6% and specificity of 58.8%. Moreover, hypertension, hemoglobin levels, contrast volume, and aortic valve area (AVA) were found to be independent predictors of AKI.Conclusions: Our study revealed that the ACEF score was an independent predictor of AKI. A simple and objective score might be very useful in predicting AKI development in patients undergoing TAVI

Laboratuvardan Kliniğe Transplantasyon Pratiği

Transplantasyon; Temel Tıbbi Bilimler, Moleküler Tıp, Genetik ve İmmünolojiden klinik uygulamalardan destek alan multidisipliner bir tıp dalıdır. Temel bilimlerdeki başarılı çalışmaların kliniğe uygulanması, klinikte karşılaşılan sorunların da, oluşturulan deneysel hayvan modellerinde irdelenmesi, elde edilen bilgilerin klinik uygulamalara aktarılması; diğer deyişle tecrübelerin “Translational” özellikli olması günümüz transplantasyon çalışmalarında bir gerekliliktir. İmmün sistemin bileşenlerinin ve reaksiyonlarının iyi bilinmesi, hücreler arası ilişkilerde greftin reddi ya da kabul edilmesinin şartlarını doğru anlamak ve uygun laboratuvar yöntemleri ile klinik durumun aydınlatılması transplantasyonda stratejik önemdedir.

Yorgunluğun basketbol serbest atısının kınematıgıne etkisi yoktur.

Kinematic analysis of basketball shooting is evolving, however the effects of fatigue on free throw shooting have not been studied. Therefore the effects of fatigue on the kinematics of free throw shooting among elite male basketball players was assessed. Ten healthy male collegiate basketball players participated in the study. Resting and fatigue heart rates of the participants were measured. After a 15 minute warm-up period, markers were placed on seven locations on the shooting arm’s side upper and lower extremities. The free throw shots were recorded with two digital cameras at a speed of 60 frames/s at a stereoscopic position. Data were analyzed with the photogrammetry technique. Each participant performed free throw shots (pre-fatigue condition) until the two successful and two unsuccessful shots were collected. Then participants completed a fatigue protocol, which included sprints and squat jumping, until reaching their volitional exhaustion and free throw shots were repeated (post-fatigue condition). The elbow, trunk, knee and ankle joint angles were measured. Successful and unsuccessful shots were compared for pre- and post-fatigue conditions. The results demonstrated that fatigue did not affect free throw shooting and there was no significant joint angle difference (p>.05) between successful and unsuccessful shots (p>.05). It was concluded that fatigue does not affect the kinematics of free throw shooting of healthy male collegiate basketball players and there were no differences in the kinematics of selected joint angles for successful and unsuccessful free throw shots.M.S. - Master of Scienc
