Long-term radiological outcomes of short-segment stabilization in thoracic burst fracture

Introduction: Short-segment (SS) transpedicular instrumentation and distraction have been used as a popular method recently due to the kyphotic angulation and adequate spinal canal decompression provided by the fusion of fewer mobile vertebra segments. This study aims to demonstrate that adequate decompression of spinal canal and kyphosis angulation can be improved by SS instrumentation and distraction in thoracic vertebrae burst fracture. Methods: Patients who were admitted to our clinic for thoracic vertebra burst fractures between 2014 and 2017 and who underwent fusion with transpedicular screws were retrospectively analyzed. Results: Both the sagittal index (SI) and canal occupation rates (COR) showed statistically significant changes between the pre-operative and early post-operative periods (pSI=0.001, pCOR=0.001). Evaluation results of the patients at 2-year follow-up; mean SI was 16.2°±1.25° and the mean COR was 6.25±2.4%. There was no statistically significant difference between both SI and CORs postoperatively and after 2 years of follow-up (pSI=0.916, pCOR=0.565). Discussion and Conclusion: We believe that SS stabilization is sufficient especially in patients with COR <40%, SI <25°, American Spinal Injury Association score E, and preserved posterior elements of the vertebra

Bu çalışma, Malatya yöresinde organik tarım tekniğinde yer alan bitki besleme uygulamalarını konvansiyonel uygulamasıyla karşılaştırarak, kayısı yetiştiriciliği için en uygun organik tarım programını oluşturmak amacıyla planlanmıştır. Çalışma 2002-2006 yıllarında Malatya ili Akçadağ ilçesi Karapınar Köyü’nde, 5 yıldır sertifikalı olarak organik tarım yetiştiriciliği yapılan, 15 yaşında, 10x10 m aralık ve mesafede dikilmiş Hacıhaliloğlu kayısı çeşidinden kurulu kayısı bahçesinde yürütülmüştür. Bu bahçenin yakınında, konvansiyonel tarım sisteminin uygulandığı, 15 yaşında ve 10x10 m aralık ve mesafe ile dikilmiş Hacıhaliloğlu kayısı çeşidinden kurulmuş bir üretici bahçesi de kontrol bahçesi olarak kullanılmıştır. Deneme tesadüf blokları deneme desenine göre 3 tekerrürlü ve her tekerrürde 3 ağaç olacak şekilde kurulmuştur. Çalışmada, organik tarım sistemine uygun 5 farklı bitki besleme uygulaması A (Toprağa Ticari Organik Gübre + Toprağa Çiftlik Gübresi + Yeşil Gübre Uygulaması), B (Toprağa Ticari Organik Gübre + Toprağa Humik Asit Uygulaması), C (Toprağa Ticari Organik Gübre + Toprağa Çiftlik Gübresi Uygulaması), D (Toprağa Organik Gübre + Yeşil Gübre Uygulaması) ve E (Toprağa Ticari Organik Gübre + Yaprağa Ticari Organik Gübre Uygulaması) yapılmıştır. Uygulamaların meyve verim ve kalitesi üzerine etkileri ile ekonomik analizleri yapılmıştır. Uygulamaların ortalama ağaç başına ve gövde kesit alanına verim değerleri üzerine etkisi %1 düzeyinde önemli bulunmuştur. En yüksek ağaç başına ve gövde kesit alanına verim değerleri sırası ile 111.30 kg/ağaç ve 0.18 kg/cm2 ile kontrol uygulamasından, organik uygulamalardan ise en yüksek verim 83.09 kg/ağaç ve 0.16 kg/cm2 ile A uygulamasından elde edilmiştir. En düşük verim ise 55.25 kg/ağaç ve 0.10 kg/cm2 ile D uygulamasından elde edilmiştir. Çalışmanın sonucunda, Malatya koşullarında verim, kalite ve net karlılık kriterleri göz önüne alınarak, organik kayısı yetiştiriciliği için A kombinasyonunun (Toprağa Ticari Organik Gübre Uygulaması + Toprağa Çiftlik Gübresi Uygulama + Yeşil Gübre Uygulaması), tavsiye edilebilir ve uygulanabilir en uygun organik kombinasyon olduğu saptanmıştır

Military jet pilots have higher p-wave dispersions compared to the transport aircraft aircrew

Objectives: For the purpose of flight safety military aircrew must be healthy. P-wave dispersion (PWD) is the p-wave length difference in an electrocardiographic (ECG) examination and represents the risk of developing atrial fibrillation. In the study we aimed at investigating PWD in healthy military aircrew who reported for periodical examinations. Material and Methods: Seventy-five asymptomatic military aircrew were enrolled in the study. All the subjects underwent physical, radiologic and biochemical examinations, and a 12-lead electrocardiography. P-wave dispersions were calculated. Results: The mean age of the study participants was 36.15±8.97 years and the mean p-wave duration was 100.8±12 ms in the whole group. Forty-seven subjects were non-pilot aircrew, and 28 were pilots. Thirteen study subjects were serving in jets, 49 in helicopters, and 13 were transport aircraft pilots. Thirty-six of the helicopter and 11 of the transport aircraft aircrew were non-pilot aircrew. P-wave dispersion was the lowest in the transport aircraft aircrew, and the highest in jet pilots. P-wave dispersions were similar in the pilots and non-pilot aircrew. Twenty-three study subjects were overweight, 19 had thyroiditis, 26 had hepatosteatosis, 4 had hyperbilirubinemia, 2 had hypertension, and 5 had hyperlipidemia. The PWD was significantly associated with thyroid-stimulating hormone (TSH) levels. Serum uric acid levels were associated with p-wave durations. Serum TSH levels were the most important predictor of PWD. Conclusions: When TSH levels were associated with PWD, uric acid levels were associated with p-wave duration in the military aircrew. The jet pilots had higher PWDs. These findings reveal that military jet pilots may have a higher risk of developing atrial fibrillation, and PWD should be recorded during periodical examinations

Effects of essential oils on egg production and feed efficiency as influenced by laying hen breed: A meta-analysis

Background and Aim: Successful rearing of laying hens to achieve optimal egg production is an endeavor that often faces various constraints and challenges, such as infectious diseases, environmental stressors, and fluctuations in feed quality. The incorporation of essential oils (EOs) into the diet of laying hens has attracted considerable attention in recent years. Therefore, our study aimed to evaluate the efficacy of EO inclusion in laying hen diets by considering the effects of production phase and breed on performance, egg quality, serum biochemistry, gut health, and antioxidant activity. Materials and Methods: The articles were obtained from the Web of Science, Scopus, Science Direct, and PubMed using the search terms “essential oils,” “laying hens,” and “phytobiotics.” Data from 27 articles and 71 experiments were grouped according to laying hen production phase and breed in the database. The EO levels ranged from 0 to 1000 mg/kg, with thymol and carvacrol being the major EOs. A mixed model was used to analyze the data. Random effects were applied to the treatment, and fixed effects were applied to EO level, production phase, and breed. Results: Egg production, feed intake, feed efficiency, eggshell quality, villus height, crypt depth, superoxide dismutase, and glutathione peroxidase levels increased linearly (p = 0.05) and egg weight and mass increased quadratically (p < 0.05) with increasing EO concentrations. An interaction was observed between the EO level egg production and feed conversion ratio (p = 0.05). Serum glucose, cholesterol, and malondialdehyde levels decreased with increasing EO concentrations (p < 0.05). Conclusion: The inclusion of EOs effectively increased egg production, feed efficiency, egg weight, egg mass, eggshell quality, oxidative enzymes, and intestinal health. In addition, the proportion of dietary EOs in lightweight laying hens was higher than that in semi-heavy-weight laying hens in improving egg production and feeding efficiency
