Evaluation of nutritional status in pediatric intensive care unit patients: the results of a multicenter, prospective study in Turkey

IntroductionMalnutrition is defined as a pathological condition arising from deficient or imbalanced intake of nutritional elements. Factors such as increasing metabolic demands during the disease course in the hospitalized patients and inadequate calorie intake increase the risk of malnutrition. The aim of the present study is to evaluate nutritional status of patients admitted to pediatric intensive care units (PICU) in Turkey, examine the effect of nutrition on the treatment process and draw attention to the need for regulating nutritional support of patients while continuing existing therapies.Material and MethodIn this prospective multicenter study, the data was collected over a period of one month from PICUs participating in the PICU Nutrition Study Group in Turkey. Anthropometric data of the patients, calorie intake, 90-day mortality, need for mechanical ventilation, length of hospital stay and length of stay in intensive care unit were recorded and the relationship between these parameters was examined.ResultsOf the 614 patients included in the study, malnutrition was detected in 45.4% of the patients. Enteral feeding was initiated in 40.6% (n = 249) of the patients at day one upon admission to the intensive care unit. In the first 48 h, 86.82% (n = 533) of the patients achieved the target calorie intake, and 81.65% (n = 307) of the 376 patients remaining in the intensive care unit achieved the target calorie intake at the end of one week. The risk of mortality decreased with increasing upper mid-arm circumference and triceps skin fold thickness Z-score (OR = 0.871/0.894; p = 0.027/0.024). The risk of mortality was 2.723 times higher in patients who did not achieve the target calorie intake at first 48 h (p = 0.006) and the risk was 3.829 times higher in patients who did not achieve the target calorie intake at the end of one week (p = 0.001). The risk of mortality decreased with increasing triceps skin fold thickness Z-score (OR = 0.894; p = 0.024).ConclusionTimely and appropriate nutritional support in critically ill patients favorably affects the clinical course. The results of the present study suggest that mortality rate is higher in patients who fail to achieve the target calorie intake at first 48 h and day seven of admission to the intensive care unit. The risk of mortality decreases with increasing triceps skin fold thickness Z-score

Darbe doppler radarlarda eş aralıklı olmayan darbe yineleme aralıklarının optimizasyonu.

In this thesis, a method of optimization of nonuniform pulse repetition interval for pulse Doppler radars is investigated. PRI jittering technique is used for the selection of inter-pulse intervals. An environment with white Gaussian noise and clutter interference is defined and applying generalized likelihood ratio test, a sufficient statistic function for the detection of the target is derived. The effect of jitter set selection on range and Doppler ambiguity resolution and clutter rejection is investigated. Jitter sets for Doppler ambiguity resolution are investigated by the minimization of the sufficient statistic function value at other estimated target velocities. Jitter sets for range ambiguity resolution are investigated by minimization of the number of ambigous hits at other estimated ranges. The clutter rejection properties of jitter sets are evaluated by defining a constraint function on zero velocity clutter rejection. The problems stated are solved using MATLAB with genetic algorithms. It is observed that there is a trade off between Doppler ambiguity resolution and clutter rejection properties of jitter sets. Low jitter values are needed for good clutter rejection. The performance of jitter sets are optimized according to range ambiguity resolution and clutter rejection properties by defining cost functions. It is observed that good range ambiguity resolution and clutter rejection can be achieved by an optimized PRI jittering technique. Finally, the effects of quantization of Doppler filter coefficients and target returns using improvement factor as the performance criterion are evaluated.M.S. - Master of Scienc

Integrated augmented reality and product lifecycle management framework for operator support optimization and improvement of reporting during the manufacturing operation

Nowadays, production environment became more and more competitive due to innovative improvements and applications in industrial systems. Manufacturers aim to implement technological solutions into their production systems from the design phase until the product’s end of life. This approach provides several benefits to manufacturers such as; reduced cost, increased productivity, reduced time-to-market etc. Augmented Reality (AR) is one of the most popular technologies which provides innovative solution to manufacturers. There is a variety of use of AR applications in manufacturing world such as; assemble, training, maintenance, recycling etc. On the other hand, the product data andits traceability became more and more important within supply chain. In order to improve their competitiveness on the market, manufacturers started to search for solutions which helps to improve production practices in terms of cost and time. PLM solutions have provided a better understanding to use of product data and improved the production systems. This project aims to develop a framework which integrates the AR and PLM context with the purpose of optimization of the support given to the operator and reporting of the manufacturing operations. An AR –PLM Framework has been developed and a demonstrator has been implemented as a proof of the concept in this project

Dielectric Properties of HDOBAMBC Close to the Smectic A-Chiral Smectic C (AC*) Transition

The temperature dependence of the dielectric susceptibility chi(g) is recalculated by making the elastic modulus K temperature dependent for the chiral smectic C phase in HDOBAMBC. For this calculation, the experimental data for the spontaneous polarization P-S, tilt angle theta and the helical pitch rho are used from literature close to the AC* transition in HDOBAMBC. The temperature dependences of the wave vector of the helical modulation q, the elastic free energy F and the critical electric field E-C are also calculated by using the temperature dependent elastic modulus K for the chiral smectic C phase close to the AC* transition in this ferroelectric liquid crystal

The association between air pollution parameters and emergency department visits and hospitalizations due to cardiovascular and respiratory diseases: a time-series analysis

Objective In this study, the association between cardiovascular and respiratory Emergency Department (ED) visits and hospitalizations and Sulfur Dioxide (SO2) and particulate matter with an aerodynamic diameter <= 10 mu m (PM10) was determined. Methods The records of a total of 632,223 people diagnosed with cardiovascular diseases (ICD-10 code I00-I99) and respiratory diseases (ICD-10 code J00-J99) at and over the age of 18 between 2012 and 2018 in three hospitals in Karaman in Turkey were examined in the present study. The daily 24-h averages for SO2 and PM10 concentrations were acquired in National Air Quality Monitoring. A time-series analysis with Poisson Generalized Linear Model was used. Results Among the air pollution parameters, the mean +/- standard deviation of SO2 and PM10 were 16.2 +/- 22.1 and 75.8 +/- 48.2 mu g/m(3), respectively. An increase of 10 mu g/m(3) in SO2 was associated with a 3% [Relative Risk (RR), 95% Confidence Interval (CI): 2-4)] increase in cardiovascular ED visit and 2% (RR, 95% CI 2-3) increase in respiratory ED visit, and 1% (RR, 95% CI 1-3) increase in respiratory hospitalizations. An increase of 10 mu g/m(3) in PM10 was associated with a 1% (RR, 95% CI 1-2) increase in cardiovascular hospitalizations. Conclusions Increases in SO2 are a risk factor for cardiovascular and respiratory ED visits, and respiratory hospitalizations. Increases in PM10 are a risk factor for cardiovascular hospitalizations.WOS:0007057663000012-s2.0-85116576697PubMed: 3461716

Hypoglossal Schwannoma Presenting Only With Headache

Hypoglossal schwannoma is a rarely encountered skull base lesion that has generally both intracranial and extracranial parts. This article reports a case of hypoglossal schwannoma that is purely extracranial and presents itself only with persistent headache. Magnetic resonance imaging delineated a mass at the skull base that consisted of both cystic and solid components, consistent with a nerve sheath tumor. Cervical approach was chosen, and the mass was completely removed. Postoperatively, the patient developed hypoglossal nerve palsy because the hypoglossal nerve was sacrificed. Hypoglossal schwannomas are briefly discussed with a literature review

Epidermal Inclusion Cyst of External Auditory Canal

Epidermal inclusion cyst is a benign cyst filled with keratin fibers, and its wall has nearly the same characteristics as the epidermis. It is commonly seen in the skin and has the tendency to slowly grow toward deeper epidermis parts and to cause cystic expansion. We report a 23-year-old woman who presented with right external otitis lasting for 2 months. The patient's complaints did not respond to treatment even after parenteral antibiotic therapy. Surgical exploration revealed epidermal inclusion cyst of the ear canal. This pathologic entity is discussed in the light of current literature

Metastatic Basal Cell Carcinoma

Basal cell carcinoma (BCC) is the most common skin cancer with a high propensity for local recurrence. The incidence of metastases from BCC is rare. We report a 65-year-old man who had BCC of the medial canthus of the left eye. In the 10-year period, he had been operated on approximately 12 times because of local recurrences. Three years after the last operation, he had a suspicious lesion on the operated area and a lumbar pain. Radiologic examination showed multiple metastatic skeletal and liver lesions. He was referred to the oncology department for radiation therapy and chemotherapy

Tongue Reduction in Beckwith-Wiedemann Syndrome With CO2 Laser

Beckwith-Wiedemann syndrome is a congenital syndrome with some anomaly in overgrowth. Most common manifestations are exomphalos, macroglossia, gigantism, and visceromegaly. Overgrowth in tongue's size caused clinical symptoms such as dysphagia, speech disorder, strong in chewing, upper-airway obstruction, and psychological problems with appearance. Cold surgical techniques are commonly used in treating macroglossia. We presented tongue reduction with laser and its early result on a child with Beckwith-Wiedemann syndrome for macroglossia
