Background: Plaster of Paris (POP) is being used in different ways in the field of medicine, dentistry and rehabilitation. One of its uses is in the manufacture of models of body segments in prosthetics and orthotics. It is used as a one-off procedure in which the used material is dismantled and discarded. The disposal of discarded materials does not allow easy decomposition which then pollutes the environment. It is not known whether this material could be reused if recycled.
Objectives: The main objective of the study was to recycle POP models and determine its reuse in producing models with identical qualities, and thus reduce environmental pollution.
Method: The procedure adopted was to break discarded models into small pieces, remove impurities and dirt; then the sample models were milled, washed, dried and pulverised. The POP models were heated to evaporate crystalline water in order to determine for how many times it could be recycled while retaining the desired strength, setting time and working characteristics.
Results: The recycled POP reached higher setting temperatures and was stronger in terms of compressive strain and strength than the virgin POP. The highest temperature recorded for recycled POP was 40°C, which was higher than that for virgin powder (32.5°C). Testing compressive strength of all cylinders in all groups showed that the average compressive strength of the recycled powder mixed with water in a ratio of 1:1 was 2407 KN/m² and the ratio of 2:3 resulted in a compressive strength of 1028 KN/m², whereas the average compressive strength of virgin POP powder mixed with water in a ratio of 1:1 was 1807 KN/m² and the ratio of 2:3 resulted in a compressive strength of 798 KN/m². There were no differences in working properties between the recycled POP and the virgin POP.
Conclusion: It was therefore concluded that under controlled conditions, such as grinding size, heating temperature, time and avoidance of contamination, used POP could be continuously recycled, resulting in stronger and workable casts.

Purpose: To analyse physical activity of patients during their hospital stay and to explore the relationship between physical activity and barriers to physical activity.
Methods: This was a secondary analysis of physical activity data for patients admitted to the internal medicine and surgical wards. Physical activity data, collected with a wireless patch sensor, was operationalized as time spent lying, sitting/standing, and walking. Barriers to physical activity included patients’ pain levels, the use of urinary catheters, intravenous tubing, oxygen lines, drains, and level of dependence. Regression analysis explored the relationship between physical activity and barriers to physical activity.
Results: Physical activity data were collected in 39 patients (aged 27–88, mean 54 years) during hospital stay. Patients were admitted for a median of 10 d (interquartile range [IQR]: 7–15 d). These patients were lying for a median of 12.1 h (7.6–17.7), sitting/standing 11.8 h (6.3–15.7), and walking 0.1 h (0–0.3) per day. Time lying during the day related to pain levels (β = 0.4 h per unit increase in pain, p < 0.01) and drain use (β = 3.1 h, p < 0.01).
Conclusions: Patients spent the most time during the hospital stay lying in bed. Improved pain management and decreased drain use may be worth exploring to increase inpatient physical activity.
Knowledge and use of contraceptive methods amongst deaf people in Ghana

Background: Persons with disabilities in general face serious barriers to sexual and reproductive health (SRH) information and services due to institutional and attitudinal barriers. However, because deaf people have unique communication and linguistic needs, which are often misunderstood or ignored, they face greater barriers than other persons with disabilities. Whilst available data indicated that there is a wide gap between knowledge and usage of contraceptive amongst Ghanaians, little is known about the level of contraceptive knowledge and usage amongst deaf people.
Objectives: The objective of the study was to investigate the level of knowledge and use of contraceptive methods amongst deaf people in Ghana with the aim of understanding their contraceptive behaviour and to improve access.
Method: The study was a participatory SRH needs assessment utilising a two-phase, sequential, mixed methods design. The study included 179 participants, consisting of focus groups with seven executives of Ghana National Association of the Deaf (GNAD), 10 male deaf adults, and 9 deaf female adults. A total of 152 deaf people, made up of students, women, and men participated in a survey, whilst one hearing person served as a key informant.
Results: The findings of the study indicated that of the 13 methods shown in the survey, only three were known to about 70% of the adults and 60% of the students. Level of knowledge of the remaining nine methods was low.
Conclusion: Clear and effective policies are needed to guide the provision of SRH information and services for deaf people in Ghana.
