Statistical Analysis of the Impact of Employees' Demographic Characteristics on Organizational Climate Perception: The Case of Süreyya Paşa Chest Diseases Hospital
İşletme olarak hastaneler, her türlü sağlık hizmetinin üretildiği, karmaşık yapılı ve yüksek düzeyde uzmanlaşmayı gerektiren sağlık kurumlarıdır. Hastaneler hem emek hem de sermaye yoğun işletme özelliğine sahip sağlık kurumlardır. Sağlık sektöründe giderek artan bir rekabet ortamı oluşmaktadır. Böyle bir ortamda rakiplerden önde olabilmek için örgütsel iklim ve örgütsel bağlılık kadar bu iki kavramı etkileyen faktörler de son derece önemlidir. Bir örgütte çalışanların örgüt amaçlarını benimsemeleri, değer yargılarını kabul etmeleri, inanç ve kurallara uygun davranışlarda bulunmaları ve kendilerinden beklenen davranışları göstermelerinin anahtarı olarak “örgütsel iklim”; işletmelerin rekabet avantajı sağlayabilmeleri ve vasıflı iş görenleri bünyelerinde tutabilmeleri için ise “örgütsel bağlılık” vazgeçilmez olarak görülebilir. Bu çalışma sağlık çalışanlarının algıladıkları hizmetkâr liderlik anlayışı çerçevesinde örgütsel iklim ve örgütsel bağlılık arasında anlamlı bir ilişkinin var olup olmadığını belirlemek amacıyla yapılmıştır. Çalışma 30.10.2017 ile 30.12.2017 tarihleri arasında İstanbul İli Kamu Hastaneler Birliğine bağlı bir devlet hastanesinde aktif olarak çalışan 495 sağlık personelinden 254’üne uygulanmıştır. Örneklem, rastgele örneklem seçim tekniği olup katılım %52,93’dür. Çalışmada veri toplama aracı olarak; Robert Stringer tarafından geliştirilmiş, örgüt iklimi ölçeği; Meyer ve Allen tarafından geliştirilmiş örgütsel bağlılık ölçeği ve çalışanların sosyal-demografik niteliklerinden oluşan bir anket formu kullanılmıştır. Ölçek ve alt boyut puanları normal dağılım gösterdiğinden cinsiyet, medeni durum; yaş, öğrenim düzeyi, kadro durumu, kıdem, kamuda çalışma süresi, toplam aylık gelir değişkenlerine göre karşılaştırılmıştır. Gruplar arasındaki anlamlı farklılık için de ikili karşılaştırmalar yapılmıştır. Örgütsel iklim ölçeği ve alt boyut puanlarının hem cinsiyete hem de medeni duruma göre, aynı zamanda yaş gruplarına, öğrenim düzeyine, mesleki kıdemine, kamuda çalışma süresine göre anlamlı farklılık göstermediği belirlenmiştir.As an enterprise, hospitals are health institutions where all kinds of health services are produced, complex structured and requiring high_x000D_

Analyses with the Video Head Impulse Test During the Canalith Repositioning Maneuver in Patients with Isolated Posterior Semicircular Canal Benign Paroxysmal Positional Vertigo
Objective: To evaluate the posterior semicircular canal (PSCC) functions using video head impulse test (vHIT) during canalith repositioning maneuver (CRM) treatment in patients with isolated, posterior semicircular canal benign paroxysmal positional vertigo (PSCC-BPPV).Methods: A total of 44 subjects comprising of 24 subjects with isolated PSCC-BPPV and 20 age- and sex-matched healthy control subjects were enrolled in the present study. vHIT was performed for the affected PSCC before and just after CRM and at the third and seventh day and first month to evaluate vestibulo-ocular reflex (VOR) gain, gain asymmetry (GA), and corrective saccades. Repeated determinations of VOR gain and GA were compared to evaluate the time course of vHIT measurements during CRM treatment in isolated PSCC-BPPV patients, and the values were also compared with the control group.Results: VOR gains and GA values were not statistically different before and after CRM and at the thirdday, seventh-day and first-month visits for the affected PSCC. Moreover, values did not differ between the BPPV and control groups, and none of the subjects demonstrated corrective saccades.Conclusion: To our knowledge, this study is the first report to investigate vHIT measurements with a time course of alterations during CRM treatment in PSCC-BPPV patients. vHIT may not provide an additional contribution for evaluating vestibular dysfunction during the diagnosis and treatment of isolated PSCC-BPPV
Childhood Nasal Foreign Bodies: Analysis of 1724 Cases
Objective:This study evaluates the characteristics of the foreign bodies removed from the nose, the treatment methods used, and the complications associated with the foreign body, and discusses the reports in the literature.Methods:Age, gender, type of foreign body, side of nose, clinical symptoms, complaints, diagnosis and treatment methods were retrospectively evaluated in all 1724 pediatric patients with foreign bodies.Results:Of the 1724 patients, 841 (48.7%) were female and 883 (51.3%) were male. Their mean age was 4.3±3.06 years (age range: 4 months-16 years). Foreign body was found on the right side in 928 (53.8%), on the left-side in 768 (44.5%) and bilaterally in 28 (1.6%) patients. The foreign bodies were inorganic substances such as beads, paper, napkins, toy parts, batteries, pencils, erasers in 1287 cases (74.7%) and organic materials such as hazelnuts, walnuts and fruit seeds in 437 cases (25.3%). The foreign bodies were extracted in outpatient settings in 1709 cases. Fifteen patients in whom the foreign body was located in the posterior region and/or who were uncooperative were treated under anesthesia. The most common complication was epistaxis. Septal perforation was seen in one patient with alkaline battery.Conclusion:In pediatric patients presented to the otolaryngology and the pediatrics clinics with complaints involving nasal obstruction, unilateral purulent nasal discharge, epistaxis, and foul odor, possibility of a foreign body in the nose should be kept in mind
Retrospective Analysis of Surgically Managed Maxillofacial Fractures in Kayseri Training and Research Hospital
Objective: To retrospectively evaluate the clinical and surgical data of patients with maxillofacial fracture (MFF) who were surgically treated at the Department of ENT and Head Neck Surgery in the Kayseri Training and Research Hospital and to compare and discuss the results with relevant literature, including that from Turkey.Methods: Data concerning the age, gender, etiology, type and site of injury, treatment modality, and postoperative complications were collected and analyzed from medical records of patients who underwent maxillofacial surgery for MFF at the Department of ENT and Head Neck Surgery in the Kayseri Training and Research Hospital between January 2013 and March 2015.Results: A total of 35 patients were surgically treated because of MFF between January 2013 and March 2015. Of the 35 patients, 28 (80%) were male, whereas seven (20%) were female. Traffic accidents (40%) were the most frequent cause of MFFs. Mandibular fractures (49.1%) were the most common fractures, followed by zygomatic fractures (31.6%). Surgical management of MFFs was performed via closed reduction (17.5%) and/ or open reduction with internal fixation by miniplates (82.5%). A total of five complications were observed in the present study: malunion (n=2), removal of fixation plate because of infection (n=2), and permanent infraorbital nerve injury (n=1).Conclusion: Based on the experience from the close proximity of the area, we think that surgeries for MFFs should be in the surgical repertoire of ENT surgeons
Discovery of therapeutic agents targeting PKLR for NAFLD using drug repositioning
Background: Non-alcoholic fatty liver disease (NAFLD) encompasses a wide spectrum of liver pathologies. However, no medical treatment has been approved for the treatment of NAFLD. In our previous study, we found that PKLR could be a potential target for treatment of NALFD. Here, we investigated the effect of PKLR in in vivo model and performed drug repositioning to identify a drug candidate for treatment of NAFLD. Methods: Tissue samples from liver, muscle, white adipose and heart were obtained from control and PKLR knockout mice fed with chow and high sucrose diets. Lipidomics as well as transcriptomics analyses were conducted using these tissue samples. In addition, a computational drug repositioning analysis was performed and drug candidates were identified. The drug candidates were both tested in in vitro and in vivo models to evaluate their toxicity and efficacy. Findings: The Pklr KO reversed the increased hepatic triglyceride level in mice fed with high sucrose diet and partly recovered the transcriptomic changes in the liver as well as in other three tissues. Both liver and white adipose tissues exhibited dysregulated circadian transcriptomic profiles, and these dysregulations were reversed by hepatic knockout of Pklr. In addition, 10 small molecule drug candidates were identified as potential inhibitor of PKLR using our drug repositioning pipeline, and two of them significantly inhibited both the PKLR expression and triglyceride level in in vitro model. Finally, the two selected small molecule drugs were evaluated in in vivo rat models and we found that these drugs attenuate the hepatic steatosis without side effect on other tissues. Interpretation: In conclusion, our study provided biological insights about the critical role of PKLR in NAFLD progression and proposed a treatment strategy for NAFLD patients, which has been validated in preclinical studies.

Combined metabolic activators improve metabolic functions in the animal models of neurodegenerative diseases
Background: Neurodegenerative diseases (NDDs), including Alzheimer's disease (AD) and Parkinson's disease (PD), are associated with metabolic abnormalities. Integrative analysis of human clinical data and animal studies have contributed to a better understanding of the molecular and cellular pathways involved in the progression of NDDs. Previously, we have reported that the combined metabolic activators (CMA), which include the precursors of nicotinamide adenine dinucleotide and glutathione can be utilized to alleviate metabolic disorders by activating mitochondrial metabolism. Methods: We first analysed the brain transcriptomics data from AD patients and controls using a brain-specific genome-scale metabolic model (GEM). Then, we investigated the effect of CMA administration in animal models of AD and PD. We evaluated pathological and immunohistochemical findings of brain and liver tissues. Moreover, PD rats were tested for locomotor activity and apomorphine-induced rotation. Findings: Analysis of transcriptomics data with GEM revealed that mitochondrial dysfunction is involved in the underlying molecular pathways of AD. In animal models of AD and PD, we showed significant damage in the high-fat diet groups' brain and liver tissues compared to the chow diet. The histological analyses revealed that hyperemia, degeneration and necrosis in neurons were improved by CMA administration in both AD and PD animal models. These findings were supported by immunohistochemical evidence of decreased immunoreactivity in neurons. In parallel to the improvement in the brain, we also observed dramatic metabolic improvement in the liver tissue. CMA administration also showed a beneficial effect on behavioural functions in PD rats. Interpretation: Overall, we showed that CMA administration significantly improved behavioural scores in parallel with the neurohistological outcomes in the AD and PD animal models and is a promising treatment for improving the metabolic parameters and brain functions in NDDs.PoLiMeR Innovative Training Network ; SNIC ; ScandiBio Therapeutics ; ScandiBio Therapeutics and Knut ; Knut och Alice Wallenbergs Stiftels
