The purpose of this study was to investigate the effect of corrective exercises and kinesio taping on the improvement of forward head improvement in female students.

In this randomized quasi-experimental study, 30 girl students aged 7 to 13 years with forward head were randomly divided into two equal groups of exercises and kinesio taping. The refresher training group performed selective exercises for 6 weeks (three sessions per hour per week). The kinesio taping group obligated to use kinesio tape in the posterior part of the neck (along with the cervical vertebrae) for 6 weeks. The improvement of forward head was compared between the two groups.

6 weeks after intervention, the improvement of forward head in corrective exercises and kinesio taping groups was 13.5% and 34.5%, respectively, and the difference between the two groups was statistically significant (P = 0.001). There was a significant difference between the effects of correction exercises and the use of kinesio tape on forward head improvement in favor of the kinesio taping group.

 The results show that both the correction exercises and the use of kinesio tape can reduce the angle of head forward. However, kinesio taping has a greater effect on forward head reduction. Therefore, kinesio taping and corrective exercises can be used to improve forward head.

Increase in the number of peoples with cancer attract many researchers in the field of medical science to find a safe approach to treat it. The application of nanotechnology in this field is very promising, and has led to the design of nanosystems with the ability of simultaneous diagnose and therapy. Based on this, the aim of this project was the synthesis a system with functionality in multimodal diagnosis and therapy.

iron oxide nanoparticles were synthesized through thermal decomposition method, and were covered by Au during five irritations using Lyon's method. Finally, cyclodextrins were attached, and then polymerized on the system. The successful preparation of the system was evaluated using different characterization tests.

Results showed the prosperous preparation of iron oxide nanoparticles with 15 nm mean diameter which was coated with a gold cover that increased the size to 35 nm. Moreover, the presence of cyclodextrin on the surface of system was confirmed by analytical characterization tests.

 The nanosystem introduced in this project, due to the presence of iron oxide and Au nanoparticles, has the ability to be used in two diagnostic approaches, magnetic resonance imaging (MRI) and computed tomography (CT) scan. Moreover, the presence of cyclodextrin and iron oxide in its structure allows it to be used as a hydrophobic drug delivery system, as well as in photothermal therapy and hyperthermia.

Inadequate ventilation with mask and difficult intubation are the most common adverse respiratory outcomes in patient undergoing anesthesia .The aim of this study was to compare Mallampati test in different sitting positions in traditional approach and during phonation for predicting difficult laryngoscopy and intubation in candidates for surgery.

In this diagnostic value study on 385 patients, in different positions and sitting with open mouth and closed mouth, Mallampati test was examined by a blind person regarding the condition of the mallmpati, laryngoscopy grade, and the severity of intubation. The results of these four positions of mallampati were compared in predicting laryngoscopy grade and the severity of intubation.

All mallampati test scenarios had acceptable diagnostic value (P < 0.001). The accuracy of the Mallampati test in supine position with open mouth was lower than in other cases, and in the both positions of sitting with abeslang and supine with open mouth, diagnostic values were not suitable for assessing difficult and comfortable mask ventilation (P > 0.050). Mallampati test accuracy in supine position with open mouth was less than other positions. However, with a low accuracy, this position had the highest sensitivity (100%). The negative predictive value in all mallampati test cases was higher than 98%, and the positive predictive value of sitting with open mouth was higher than other positions with the value of 4.7%.

 According to the results of this study, the Malamapati test in the position of supine with abeslang was better in determining the severity of laryngoscopy and intubation.</div>

With more than 40 years of research on the effects of glucose-insulin-potassium (GIK) solution on the clinical consequences of heart surgery, its use and impact are still challenging, Therefore, the aim of this study was to investigate the effect of GIK solution on clinical outcomes after pediatric heart surgeries with cardiopulmonary bypass.

This clinical trial study was performed on 49 patients undergoing cardiac surgery by using cardiopulmonary bypass in children aged younger than 12 years in Shahid Chamran hospital, Isfahan, Iran. Patients were divided into two groups of GIK (25 people) and control (24 people). The GIK group received GIK solution, and the control group received normal saline solution. Arrhythmia, the frequency of taking insulin and adrenaline drugs, the need for cardiac shock, hospitalization and intensive care unit (ICU) time, and blood pressure were recorded in both groups. Data were analyzed using independent t, chi-square, and repeated measures ANOVA tests.

The use of GIK solution significantly reduced the need for postoperative shock, the frequency of arrhythmia, duration of hospitalization, and the amount of inotrope drugs in comparison with the control group (P < 0.05).

 According to the results of the study, the use of GIK solution during cardiac surgery can reduce clinical outcomes such as hospitalization and ICU time, the need for cardiac shock, and arrhythmia after open-heart surgery in pediatric patients.

Focusing on various educational, research, and clinical roles of Clinical Informaticist (CI), it is necessary to joint CIs to the clinical team as a member of patient care unit. CI can play an important role in improving medical services and community health by teaching information skills, training health information literacy to patient, and helping to search and retrieve information in research and clinical teams. It should be recommended that having such significant roles in the health care context requires CIs’ efforts to improve their skills and abilities, as well as to develop official and non-official relevant educational infrastructures in the health system of each country.
