Efficacy of a Condom Negotiation Intervention among High Risk Iranian Women in Tehran, Iran Hot!
Background: Development of tailored interventions to promote condom use seems essential in countries with traditional gender role definitions. Learning condom influence strategies could be helpful when it is difficult for women to initiate sexual communication. These strategies have been targeted in a safer sex skills building intervention among high-risk women in Tehran, Iran.
Methods: We conducted this study among 50 high-risk women who registered for counseling and HIV testing at Imam Khomeini Hospital in Tehran, Iran, 2012-2013. Participants were assigned to two groups: 1) routine 15 minute pre-test HIV counseling, or 2) routine counseling besides communication skills building monthly sessions for six months. Pre and post-tests were taken at baseline and six months. We designed an intervention based on Information-Motivation-Behavior theory. Condom influence strategies were used in the construct of the questionnaire and intervention materials.
Results: After six months participants in the intervention group were able to implement influence strategies to promote partners’ condom use (P = 0.01). Risk information and relationship conceptualizing were more endorsed post-intervention (P = 0.02, P =0.006). In addition, partner communication had significantly improved in the case group (P < 0.001).
Conclusions: We found that condom influence strategies could be considered in improving current counseling sessions, as an effective intervention to minimize HIV and other Sexually Transmitted Infections (STIs) transmission among high-risk women. We recommend this skill-based intervention for condom negotiation to empower at-risk sexually active women.

Dosimetric Comparison between 9F-IMRT, Single Arc VMAT and Dual Arc VMAT for Postoperative Cervical Cancer Patients with Para-aortic Lymph Node Metastasis Hot!
Background: The aim of this study was to compare the dosimetric parameters of 9 field intensity modulated radiotherapy (9F-IMRT) and two kinds of volumetric modulated arc therapy (VMAT) for postoperative cervical cancer patients with paraaortic lymph node (PALN) metastasis, and to provide the reasonable selection of the cervical cancer patients with para-aortic lymph node metastasis who need postoperative radiotherapy in clinic.
Methods: Fifteen patients of postoperative cervical cancer patients with para-aortic lymph node metastasis were planed with the same dose prescription and optimization parameters by means of 9-field IMRT (9F-IMRT), a single arc (Arcl) and dual arc (Arc2) VMAT, respectively. The dosimetric differences of planning target volume (PTV), organs at risk(OAR), the number of monitor units (MUs) and treatment time were compared among the three treatment plans.
Results: The conformity index (CI) and the homogeneity index (HI) of PTV for Arc2 plans were superior to 9F-IMRT (P <0.05). The V40, V50 of the rectum, V50 of the intestine, bladder and femoral head for Arc2 plans were better than 9F-IMRT plans. V50 of the femoral head and the mean dose of kidney for Arc1 and Arc2 plans were all better than 9F-IMRT plans. The number of MUs of 9F-IMRT plans (1,105.27 ± 107.12) was significantly higher than the Arc1 plans (755.23 ± 225.98) and Arc2 plans (967.24 ± 198.41), the difference was statistically significant (F = 12.736, P < 0.01). The treatment time of 9F-IMRT plans (430.47 ± 36.45) was significantly higher than the Arc1 plans (304.20 ± 48.42) and Arc2 plans (332.93 ± 47.62), the difference was statistically significant (F = 33.180, P < 0.01).
Conclusion: Compared to 9F-IMRT, Arc1 and Arc2 plans can better to meet the clinical requirements for the postoperative cervical cancer patients with para-aortic lymph node metastasis. And the Arc2 VMAT plans is superior to Arc1 VMAT plans, there will significantly improve the treatment efficiency.
