On the basis of breast anatomical and physiological changes during pregnancy, and parity and breastfeeding, full-term pregnancies and parities with efficient BF significantly reduced the risk of breast cancer compared with nonpregnant and nulliparous women or those who never breastfed. The number of children should ideally be limited to 1-3, and the cumulative duration of BF not less than 25-36 months. We would recommend 1-3 pregnancies and a BF duration not less than 18 months, with best results being achieved with 24 months per child.

Introduction: After menopause women experience vaginal atrophy related to hormonal changes and estrogen deficiency. The purpose of this paper was to evaluate the effect of the fractional CO2 laser on the quality of life, vaginal atrophy symptoms, and urine incontinency in menopause women. Methods: This prospective study was conducted among 140 women from 2017 to 2018 in Yas hospital, Tehran University of Medical Sciences. They encountered the fractional microablative CO2 laser system three times at four-week intervals. The short form of the Health Questionnaire (SF-12) and the Female Sexual Functional Index (FSFI) questionnaire were utilized to assess the participants’ quality of life. Also, the standard measuring tools including the vaginal health index (VHI) and International Consultation on Incontinence Questionnaire (ICIQ) Form were used to evaluate the vaginal atrophy symptoms. Results: The quality of life improved significantly in somatic, social function, and mental health. In the sexual context, arousal and satisfaction status improved significantly. Also, the frequency of urinary incontinence, enuresis, urgency, and the leak improved significantly (P<0.05). Among the scale variables for urinary function, it was seen that the urgency impact had no improvement. All vaginal indices improved (P<0.05). Conclusion: The fractional CO2 laser can be effective in treating vaginal atrophy and urinary symptoms. Besides, it improved the quality of life and the sexual function of post-menopausal women.

To our knowledge, this is the first study that demonstrated an increase in the risk of post-transplant TB by increasing the duration of pre-transplant hemodialysis and the number of post-transplant rejection episodes as 2 immunocompromised states. Further study is needed to clarify our new findings, specifically in relation to different immunosuppressive regimens.

Introduction: Low back pain (LBP) is a very common musculoskeletal disorder. The big burden of disease necessitates investigating a more effective modality of treatments with more persistence and also fewer side effects. Low power laser has been proved as a pain reducing modality, but there is a lack of studies comparing it with other treatments and also among the Iranian race and society. The purpose of this study was to evaluate the effect of low-level laser on patients with LBP. Methods: Our study was a single-blind, randomized controlled trial. Forty subjects, aged between 20 to 70 with LBP participated in the study. Their pain severity scale was 3-10 according to the visual analogue scale of pain (VAS). They were randomly assigned to two groups, a case group (true laser) and a control group (sham laser). Naproxen was prescribed with a free dose (250-1000 mg/ daily) to both groups. We evaluated patients’ subjective pain, functional status (using the Roland Morris disability questionnaire), spinal range of motion (ROM) and spinal tenderness at the basic time, one month and 3 months after treatment. The true laser group received 12 sessions of laser (160 mW) and the control group took 12 sessions of sham laser (the same laser instrument in off status). An infrared laser GaAlAs, wavelength 808 nm, power 160 mw and spot size 1 cm2 and power density 0.16 J/cm2 in continuous mode was used in treatment. We applied the laser to articular spaces of vertebral column, adjacent paravertebral points, pain radiating areas, tender points and also pain-controlling acupuncture points. Results: Of the 40 participants in the study, 6 persons were excluded and thus the data obtained from 34 participants were statistically analyzed. There was significant improvement in pain (P<0.001 for both groups), functional status (Case group: P<0.001; control group: P=0.004) and spinal ROM (Case group: P<0.001; control group: P=0.007) in both groups at the end of the first month, but these gains persisted for 3 months only in the case group (P<0.001). Regarding spinal tenderness, it was disappeared in 89.47% of the patients in the true laser group at the end of one month but remained unchanged in 73.33% of the subjects of the sham laser group. Conclusion: We concluded that laser therapy (in combination with NSAIDs) is an effective and long-lasting therapeutic strategy in bringing relief from LBP without any significant side effect.

Results showed a statistically significant improvement in the laser scanner of the hair growth group compared with laser hat and the control group. The study showed that treatment with new laser devise had a promising result without any observable adverse effects.
