Effect of mental fatigue on performance, perceptual and physiological responses in orienteering athletes.

Background: Mental fatigue seems to impair the athletes' performance; however, in sports with high cognitive demand, such as orienteering, this negative effect could be attenuated during the race. Therefore, this study investigated mental fatigue effect on performance, perceptual, and physiological responses in orienteers.

Methods: Fifteen male orienteers (30±8 years) participated in the study.

Assessment of quality of life of nasopharyngeal carcinoma patients with EORTC QLQ-C30 and H&N-35 modules.

Purpose: The current study reports on long-term quality of life (QoL) status after conventional radiotherapy in 187 nasopharyngeal carcinoma patients from 14 centers in Turkey.

Patients And Methods: Patients with the diagnosis of nasopharyngeal carcinoma, who were treated in 14 centers in Turkey with minimum 6 months of follow-up and were in complete remission, were asked to complete Turkish versions of EORTC QLQ-C30 questionnaire and the HN-35 module. Each center participated with the required clinical data that included age at diagnosis, gender, symptoms on admission, follow-up period, treatment modalities, radiotherapy dose, and AJCC 1997 tumor stage.

The role of technetium-99m methoxyisobutyl isonitrile scintigraphy in suspected recurrent breast cancer.

The aim of this study was to determine the role of technetium-99m methoxyisobutyl isonitrile (99mTc-MIBI) scintigraphy in the evaluation of recurrence and metastases in breast cancer patients with mastectomy and/or radiotherapy. A prospective study was designed to assess the accuracy of 99mTc-MIBI scintigraphy in 36 patients (mean age 49 years) with suspected recurrent breast cancer. The scintigraphic studies were correlated with radiological findings and/or with histopathology.
