RESUMEN
BACKGROUND: This study was designed to observe the effect of antihypertensive treatment on blood pressure (BP) and target organ damage in patients followed up according to the American Academy of Pediatrics Hypertension Guidelines (AAPG). The results were also assessed in comparison with the definitions and target organ damage according to the European Society of Hypertension Guidelines 2016 (ESHG). MATERIALS AND METHODS: A total of 44 (34 male) out of 140 patients were enrolled in the study and the mean age was 14±3.19years. The follow-up period was at least 12months. All patients underwent the following assessments: anthropometrical measurements of body mass index (BMI), left ventricular mass index (LVMI), and biochemical parameters according to the relevant guidelines. The pre-treatment and post-treatment datasets collected were compared. RESULTS: The frequency of symptomatic patients decreased from 88% to 30%. After treatment, 29.4% (n=13) of patients still had elevated and stage 1 hypertension (HT) according to the AAPG. These patients were older and had higher BMI z-scores, LVMI z-scores, mean BP indices, and also had longer symptom duration than normotensive patients (P<0.001). When patients were assessed according to the ESHG, 34.1% (n=15) of patients had high-normal stage 1 and stage 2 HT. While 53.3% (n=8) of the patients aged 13-15years were classified as having high-normal stage 1 and stage 2 HT according to the ESHG, 33.3% (n=5) were classified as having elevated BP and stage 1 HT according to the AAPG. Additionally, 36.4% (n=4) of the patients aged≥16years were classified as having high-normal and stage 1 HT according to the ESHG, whereas 45.5% (n=5) were classified as having elevated BP and stage 1 HT according to the AAPG. CONCLUSION: To control HT in children with higher BMI z-scores, higher LVMI z-scores, and higher BP indices, an earlier and more intensive approach is needed. Considering that the duration of exposure to HT may also affect the LVMI, adjusting age and gender or decreasing the current thresholds for LVMI may lead to an earlier diagnosis for more patients. According to the present classifications, the ESHG covers more children aged between 13 and 15years in contrast to the AAPG, which covers more patients aged≥16years. However, further studies are needed to confirm these results.

STUDY DESIGN: Retrospective descriptive study. OBJECTIVES: The present study aimed to investigate the rate of using orthosis among spinal cord injury (SCI) patients for whom orthosis was recommended for standing and walking, the relationship between the clinical and demographic characteristics of SCI and the use of orthosis and the reasons for not using orthosis. SETTING: Ankara Physical Medicine and Rehabilitation Training and Research Hospital, Turkey. METHODS: The study included 62 SCI patients for whom orthosis was recommended for standing and ambulation. The patients were classified into two groups as individuals using and not using the recommended orthosis every day in order to evaluate the effect of age, gender, residence, duration of disease/recommended duration of orthosis, recommended orthosis, lesion level-degree, lower extremity tonus-range of motion and ambulation level on the frequency of orthosis use. RESULTS: The orthosis most commonly recommended was hip-knee-ankle-foot orthosis with waist or pelvic belt (45.2%). Of the patients, 25.8% have never used the orthosis. The most common reason for not using the recommended orthosis was the failure to facilitate the daily life activities of the patient (30%), the difficulties in putting them on and taking them off (20%), the belief that it is unnecessary (15%) and the pressure (15%). In addition, the assessed clinical and demographic features were detected as not important risk factors for not using orthosis. CONCLUSION: At least one out of four patients with SCI do not use the recommended lower extremity orthosis. Selecting eligible patients, patient training and follow-up are important for increased frequency of orthosis usage.

Most diseases result in metabolic changes. In many cases, these changes play a causative role in disease progression. By identifying pathological metabolic changes, metabolomics can point to potential new sites for therapeutic intervention. Particularly promising enzymatic targets are those that carry increased flux in the disease state. Definitive assessment of flux requires the use of isotope tracers. Here we present techniques for finding new drug targets using metabolomics and isotope tracers. The utility of these methods is exemplified in the study of three different viral pathogens. For influenza A and herpes simplex virus, metabolomic analysis of infected versus mock-infected cells revealed dramatic concentration changes around the current antiviral target enzymes. Similar analysis of human-cytomegalovirus-infected cells, however, found the greatest changes in a region of metabolism unrelated to the current antiviral target. Instead, it pointed to the tricarboxylic acid (TCA) cycle and its efflux to feed fatty acid biosynthesis as a potential preferred target. Isotope tracer studies revealed that cytomegalovirus greatly increases flux through the key fatty acid metabolic enzyme acetyl-coenzyme A carboxylase. Inhibition of this enzyme blocks human cytomegalovirus replication. Examples where metabolomics has contributed to identification of anticancer drug targets are also discussed. Eventual proof of the value of metabolomics as a drug target discovery strategy will be successful clinical development of therapeutics hitting these new targets.

The aim of this study was to determine the development, location, and size of the urinary bladder during the fetal period. The study was performed on 149 human fetuses between 9 and 40 weeks of gestation. The location of the urinary bladder with respect to transverse plane between the highest point of pubic symphysis and the sacral promontory and median sagittal plane was first determined. The dimensions and the angle of the urinary bladder were measured, and bladder shapes were determined. In addition, the edges of the vesical trigone were measured. There was no significant difference between sexes for any of the parameters (P > 0.05). A significant correlation was observed between all parameters and gestational age (P < 0.001). The urinary bladder was located above the transverse plane in most of the cases (83%) and in the median sagittal plane in every case. It was determined that the angle of bladder did not change and the mean value of the angle was 151 degrees during the fetal period. Bladder was categorized into four different shapes (ellipsoid, round, cuboid, and triangular), and the most common shape found during the fetal period was cuboid. The vesical trigone was an isosceles triangle during the fetal period. The new data provided by this study will enable evaluation of the development of the fetal urinary bladder, and should be useful in several fields such as anatomy, fetopathology, medical imaging, obstetrics, and pediatric urology.

The incidence of Candida dubliniensis in immunocomprimised patients in Turkey has not yet been determined. In this study the presence of C. dubliniensis in oral rinse samples of human immunodeficiency virus (HIV)-positive patients and healthy controls were investigated. Phenotypic tests like inability of growth at 45 degrees C, colony formation on Staib agar, intracellular beta-D-glucosidase activity, carbohydrate assimilation profiles and polymerase chain reaction with species-specific primers (DUBF and DUBR) were carried out for differentiation of C. dubliniensis. Of the 35 patients, four (11.4%) had C.dubliniensis in their oral cavity. Antifungal susceptibility testing of these C. dubliniensis isolates showed fluconazole MICs ranging from <0.06 to 32 microg ml(-1) and amphotericin B from <0.06 to 0.25 microg ml(-1). One isolate was dose-dependently susceptible to fluconazole (32 microg ml(-1)). This study demonstrates C. dubliniensis in HIV-positive patients from Turkey.

We aimed to form a risk prediction model to assess the probability of intrahospital death in cancer patients at the time of hospitalisation. The medical records and the relevant clinical parameters of cancer patients who died in or who were discharged from a teaching hospital between 1997 and 2000 (n = 334) were reviewed to explore the determinants of intrahospital death, which later were verified prospectively (n = 131). Eastern Cooperative Oncology Group (ECOG) performance status of four, short duration of disease (on a logarithmic scale), emergency admission, low haemoglobin (Hb) value (on a linear scale) and lactate dehydrogenase (LDH) value greater than 378 micro/ml were significantly and independently associated with the risk of intrahospital death. This model had a receiver operating characteristic area of 0.88 in the derivation cohort and 0.82 in the validation cohort. Using readily available clinical parameters, it is possible to devise an accurate and applicable risk prediction model for the hospitalised cancer patients.
