Long-term patient and graft survival in our center is similar to that reported by other centers at an international level.
  Neuropsychiatric disorders represent one of the first causes of disability worldwide. Recognizing the main causes for hospitalization may allow the implementation of interventions to prevent hospitalization and promote ambulatory care.
 
  To describe the trends of mental disorders requiring hospitalization in a neuropsychiatric referral center of a middle-income country.
 
  Observational, cross-sectional, and analytic study. Information was obtained from dismissal letters and from the Department of Epidemiology database in a 16-year period at a neuropsychiatric referral center. Diagnoses and trends through this period were obtained using Spearman's correlation.
 
  Schizophrenia represented most of the cases (19%), followed by bipolar disorder (13%). Psychotic disorders (PD) were found to contribute the most to the length of stay (43.76%), followed by mood disorders (MD) (39.07%). Schizophrenia-related dismissals diminished through the years (
  = -751; 
  = 0.001), whereas depression-related disorders increased (
  = 0.857; 
  < 0.001).
 
  PD are the first cause of neuropsychiatric hospitalization. MD have an increasing frequency of hospitalization. Longer-stay disorders reflect global and economic burden of disease trends. These results might guide interventions that reduce hospital-based models of care, which represent a great burden in low and middle-income countries. Studies aiming to explain the trends reported are needed.

The actors involved in the development of the journals must fulfill their purposes to improve the quality of the publications of the national journals and contribute to improve the quality of care.Endotracheal intubation can be difficult in the emergent situation, and it is important to have an appropriate backup strategy. Supraglottic airway devices have provided an alternative method for pediatric airway management that is relatively easy to learn, with a high success rate. This issue reviews the use of supraglottic airway devices in pediatric patients including common devices, indications and techniques for placement, and complications associated with their use. The use of supraglottic airway devices in the patient with a difficult airway is also discussed.Deep vein thrombosis (DVT) can present with a variety of nonspecific signs and symptoms, and can involve the upper or lower extremities.  https://www.selleckchem.com/products/cinchocaine.html  Management of patients with DVT has changed markedly over the last 10 years, moving from hospital admission for initiation of anticoagulation to outpatient management. Diagnosis requires a risk stratification process involving clinical decision rules, D-dimer testing, and ultrasonography. Once the diagnosis is confirmed, the patient should be engaged in shared decision-making regarding treatment options. Recurrent DVT, as well as managing DVT in pregnant women, the elderly population, and patients with malignancies are also discussed.
  The decision regarding the selection of extraction or non-extraction orthodontic treatment is a common challenge in orthodontic treatment planning.
 
  The objective of this study was to compare the effects of extraction and non-extraction orthodontic treatment on the soft tissue profile of borderline class I patients.
 
  In this retrospective study, 70 patients were selected from among those referred to the Department of Orthodontics of the Faculty of Dentistry at Hamadan University of Medical Sciences in Iran. The inclusion criteria were skeletal class I, 4-10 mm of space deficiency, and the possibility of applying both extraction and non-extraction orthodontic treatment. All patients underwent fixed orthodontic treatment with the use of 0.022-inch-slot edgewise brackets. The patients were divided into 2 groups (n = 35) according to the 4-premolar extraction or non-extraction treatment plan. The 2 groups were compared by means of the cephalometric analysis.
 
  There were 11 males and 24 females at a mean age he incisors moved forward in the non-extraction group and backward in the extraction group.
  The oral environment can negatively affect the physical properties of fiber-reinforced composite (FRC) materials, which can lead to the deterioration of mechanical stability and reduce the span of their clinical usefulness.
 
  The aim of this study was to determine the influence of artificial saliva on the selected mechanical properties of FRC.
 
  The core of the polymer material selected for the study was a bundle of ultrahighmolecular-weight polyethylene (UHMWPE) fibers. Fourteen samples were stored in an incubator at 37°C, in 20 mL of artificial saliva solution, and weighed on days 1 and 28. At the same time, mechanical tests were performed, including the measurements of Young's modulus, tensile stress, maximum tensile force, and tensile deformation.
 
  The analysis of basic statistics together with the results of the Shapiro-Wilk test and the distribution of Spearman's rho coefficient showed a strong negative relationship between the pair of variables - tensile deformation and the sorption of synthetic saliva.
