The caesarean section is now the most frequent surgery performed on women at the reproductive age. It is known that caesarean section is associated with risks for the mother and baby, not only in the current pregnancy but also for future pregnancies. Taking into account these consequences and the rising trend of performing caesarean sections globally, strategies and recommendations have been fo...

Advocacy has a role to play in any eye care initiative. It can help individuals or organisations to obtain more resources, and it can support programme implementation and service delivery. This article focuses on using advocacy as a tool for improving the delivery of eye care services – both in terms of reaching more people, and in terms of improving the quality of services available for specif...

pregnancy, labor and delivery are known to be associated with higher rate of fetal and neonatal complications in old primigravidas. in a period of 5 rears (2531 - 36) there were 30000 deliveries at amin hospital, among them, there are records of 355 deliveries in primigravidas over 35 years of age who are included in this retrospective study. comparison with the same number of primigravidas und...

PURPOSE To demonstrate and characterize dynamic multileaf collimator (DMLC) tracking of respiratory moving targets that are spatially localized with a single kV X-ray imager during arc radiotherapy. METHODS AND MATERIALS During delivery of an arc field (358 degrees gantry rotation, 72-sec duration, circular field shape), the three-dimensional (3D) position of a fiducial marker in a phantom wa...

Herein we present the case of a healthy 29-year-old primigravida who had spontaneous term vaginal delivery complicated by postpartum development pneumomediastinum with mild pneumothorax, after pushing in an inverted hands-and-knees position for 3 hours. She was managed conservatively and experienced complete resolution symptoms without intervention.

attitudes to humankind will have different effects on health service delivery. health might used to be intended to provide physical health in the past; today, however, many researchers and clinicians consider the concept health to be beyond physical health. in support of this claim, it is enough to indicate that the bio-psycho-social model has for years been held by scientific communities to be...

the application of chemotherapy in cancer treatment has been limited due to cause side effects such as toxicity against normal cells and drug resistance. in recent years, numerous studies have been focused on using natural products with chemotherapeutic drugs to enhance therapeutic efficiency and reduce cytotoxicity. on the other hand, encapsulation of drugs into nanoparticles (nps) can improve...

The spatial vectorcardiogram and the spatial ventricular gradient of normal subjects in the last trimester of pregnancy and in some of the same subjects following delivery have been studied. It was found that the vectorcardiograms could be divided into two groups on the basis of the form of the QRS sfi-loops, as has been previously reported for other normal subjects. In some instances records t...

Volumetric-modulated arc therapy (VMAT) is an effective but complex technique for delivering radiation therapy. VMAT relies on precise combinations of dose rate, gantry speed, and multileaf collimator (MLC) shapes to deliver intensity-modulated patterns. Such complexity warrants the development of correspondingly robust performance verification systems. In this work, we report on a remote, auto...

Tomotherapy is the delivery of intensity modulated radiation therapy using rotational delivery of a fan beam in the manner of a CT scanner. In helical tomotherapy the couch and gantry are in continuous motion akin to a helical CT scanner. Helical tomotherapy is inherently capable of acquiring CT images of the patient in treatment position and using this information for image guidance. This revi...
