Purpose: This study investigated whether hypofractionated adjuvant radiotherapy (RT) increased breast-related complication(s) compared to conventional fractionated RT in reconstructed breast cancer patients. Methods: We conducted a retrospective review including 349 breast cancer patients who underwent immediate breast reconstruction following mastectomy or breast-conserving surgery (BCS) between 2009 and 2018 at two institutions. All patients were treated with adjuvant RT via either a conventional fractionated or hypofractionated regimen. We defined a major breast complication as a breast-rel

Nowadays, the issue of service quality for service-provider organizations specifically banks is of considerable importance. The service-provider organizations (specifically governmental banks) are aware from the necessity of getting satisfaction of customer and assessing quality of services. In this research, we evaluate and analyze the gap of expected and current service quality. In fact, the gap between customer´s expectations of bank services and customers perceptions is assessed based on the hierarchical service quality model (HSQM), which has been introduced by Brady and Cronin in 2001.

Background: Hip abductor muscles play a critical role in stabilizing the pelvis during functional activities. A decline in hip abductor strength is associated with impaired balance and an increased risk of falls, particularly in elderly females who experience physiological changes and age-related muscle loss. Although limb dominance has been proposed to influence lower extremity muscle strength in young adults, no studies have yet examined differences in hip abductor strength between the dominant and non-dominant limbs in elderly females. Furthermore, the relationship between hip abductor stre

Purpose Revolutions have occurred over the last 3 decades in the management of patients with colorectal cancer. Most advances were in rectal cancer surgery, especially after the introduction of the total mesorectal excision (TME) by Heald. However, no parallel advances regarding colon cancer surgeries have occurred. In 2009, Hohenberger introduced a new concept trying to translate the survival advantages of TME to patients with colon cancer.
