Plastics in healthcare

Wastes generated from healthcare practices are a serious problem for humans as well as for the environment. In this study, an attempt was made to use mixed solid medical waste (WPN) which consisted of shredded waste plastic and chopped waste needles for partial replacement of natural fine aggregate (sand) in concrete mixes at 0%, 2%, 4%, 6%, 8% and 10% by weight.

Polyhydroxyalkanoates (PHA) are polymers, which are produced by microorganisms in the form of granules under unbalanced growth conditions. They are biocompatible, biodegradable and sustainable, which makes it suitable for synthesising biomedical apparatus. Devices such as sutures, orthopaedic devices, cardiovascular implants, implant patches can be prepared using different combinations of this polymer. The polymer and its composites being biodegradable and sustainable can take over the conventional plastics in near future.

Those of us involved in the healthcare of women have seen a remarkable transformation in screening techniques for cervical cancer and its precursors since the mid 1990s.  The staid old Pap smear technique of scraping cells from the cervix with a wooden spatula and cotton-tipped applicator and smearing them onto a glass slide is a thing of the past in most practices. We now use plastic collection devices to transfer cells from the cervix into a preservative which is sent to the lab for liquidbased cytology and reflex human papillomavirus (HPV) testing.

The tuberculosis (TB) epidemic is historically anchored in South Africa’s Western Cape province, and long precedes the HIV epidemic. This is despite the generally better socio-economic status of the population and greater overall healthcare expenditure in this region than in other provinces. Contributing factors include overcrowding, alcohol abuse, poverty, and administrative neglect of the National TB Programme (NTP).1 This traditional ‘Cape’ epidemic is now being significantly augmented by an HIVassociated TB epidemic.

At the beginning of the new millennium the request for innovation increased. Complex manufacturing, miniaturization of the components, development of the Internet or healthcare are in need of new technologies provided by researchers who are capable to introduce them. The book “New Technologies - Trends, Innovations and Research” presents contributions made by researchers from the entire world and from some modern fields of technology, serving as a valuable tool for scientists, researchers, graduate students and professionals....

Every year,Americans use over one billion sharp objects to administer healthcare in their homes. These sharp objects include lancets, needles, and syringes. If not disposed of in puncture-resistant containers, they can injure sanitation workers. Sharp objects should be disposed of in hard plastic or metal containers with secure lids. The containers should be clearly marked and be puncture resistant.
