Reproductive hormones and reactive oxygen species produced by either hormonal or aerobic metabolism have been implicated in carcinogenesis of the breast and disease progression. Perturbations in the homeostasis of female reproductive hormones and oxidative stress indices in breast cancer (BCa) could be used for monitoring disease prognosis. ⋯ Postmenopausal women with BCa at different stages have increased estradiol, antioxidants, lipid peroxidation, and oxidative stress index suggesting that these indices may be useful for clinical assessment and monitoring progression of breast cancer.

To evaluate the effect of various aging periods and different surface preparation methods on microtensile bond strength (μTBS) for composite repair. ⋯ Different surface preparation methods, various aging periods, and the interaction of both affected the repair μTBS of the tested nanohybrid composite resin.

To evaluate the effect of multiple-use and sterilization on cyclic fatigue and shaping ability of heat-treated nickel-titanium (NiTi) rotary instruments. ⋯ The effects of repeated use and autoclaving on the cyclic fatigue resistance of HyFlex CM, ProTaper Next, and Twisted File were not significant. Canal transportation increased mostly in the apical region. The amount of resin removal decreased as the number of use increased for ProTaper Next and Twisted File instruments.

Obstetric fistula is a serious public health problem affecting women in low- and middle-income countries. It is characterized by continuous leakage of urine and/or feces from the vagina as a result of injuries sustained from childbirth. It has continued to exist in Nigeria because the publicly funded health-care system has failed to provide quality, equitable, accessible, and affordable maternal health care. ⋯ Universal health coverage is currently not obtainable in Nigeria. When implemented, it will eliminate the existing inequality in access to health care, thereby allowing the poor and vulnerable citizens access to quality maternity care and safe delivery. A comprehensive health insurance cover for all pregnant women regardless of socioeconomic status, priority setting in resource allocation, and public-private partnership are advocated for eradication of obstetric fistula in Nigeria.

The National Surgical Obstetric and Anaesthesia Plan is an invaluable country resource with the capacity to promote increased access to safe and affordable surgical and anaesthesia care if implemented. Although cost of implementation is only a fraction of Health Sector Strategic Plan cost in the countries with costed plans, it is important that the funding of the plans is based on sustainable financing strategies. This will ensure appropriate and timely implementation and sustainability of the plan itself. The aim of this review was to discuss and make recommendations on innovative and sustainable strategies for financing national surgical plans in sub-Saharan Africa.
