Abstract

The main goal of this study is to elaborate and evaluate the physicochemical properties of the synthetic biphasic calcium phosphate (BCP) powder: an associate compound of hydroxyapatite (HA): Ca10(PO4)6(OH)2 and beta-tricalcium phosphate (?-TCP): Ca3(PO4)2. The new compound BCP has two advantages: high bioactivity (HA) and fast biodegradation (?-TCP). The obtained powder of BCP was prepared by the precipitate method. XRD analysis confirmed the synthetic material contained both HA and ?-TCP crystalline phases. SEM images showed that the small particles of HA attached to bigger particles of ?-TCP in the structure morphology of BCP. The in vitro experiment was carried out in static condition by soaking of a series of 50 mg BCP powder in 100 ml of simulated body fluid solution at different period of soaking time. The XRD and SEM methods studied the microstructureand chemical bond after soaking. The obtained results confirmed the bioactivity of synthetic BCP material by the formation of a new apatite layer on its surface.

Abstract

This study identified the best surgical mesh repair techniques for inguinal hernia and prevalence of wound healing post-mesh repair. The cross-sectional study design used cluster sampling for data collection. Of the 120 respondents, 48.3% preferred anterior tension-free mesh repair and 49.2% Lichtenstein mesh repair, both identified as the common surgical techniques in eastern Sri Lanka. About 82.5% of the respondents (n = 99) healed while 17% (n = 21) had recurrence of hernia after one month. Nevertheless, 2.5% of the total respondents said that the hernia repaired after one month but less than two months; and 97.5% of the interviewees stated that they recovered in less than one month regardless of the surgical mesh repair technique. Respondents aged 30–39 faced little impact on healing time with mesh repair (p = 0.4393), while those aged 40–49 probably had also longer healing time (p = 0.3947). Recovering period differed significantly (p = 0.862), on pain ordiscomfort, especially when bending over, coughing or lifting heavy objects.

Abstract

Calcium phosphate ceramics consist of materials such as hydroxyapatite, tricalcium phosphate (TCP), calcium phosphate cement (CPC), biphasic calcium phosphate, etc. CPCs have been used for filling bone defects in dentistry and orthopedics. Among these materials, ?-tricalcium phosphate is suggestedas an ideal candidate for bone graft in hard tissue engineering due to its high biocompatibility, bioactivity and bone bonding. The preparation, as well as the application of this powder material, has been the important topic of research in material science. In this paper, ?-tricalcium phosphate (?-TCP), a component that has chemical formulation similar to bone structure, was synthesized by the precipitate method and then calcinated at 1000oC for 5 h. The physico-chemical properties of synthetic material were examined by XRD, FT-IR and SEM methods. In vitro experience was also carried by soaking ?-TCP simulated body fluid powder in a different period of time. Obtained results confirmed the quality of ?-TCP synthetic material and its bioactivity.

Abstract

This clinical audit identified the compliance rate of ultrasound users to the standard operating procedures (SOP); and identified the factors that led to a compliance rate of ultrasound human users. The review was conducted for six days in a private radiologic academy in Indonesia. Only 23 subjects selected randomly were audited. Of the 23 participants, there were 11 males and 12 females. Of the 11 males, seven were compliant, and three were non-compliant. Of the 12 females, eight were compliant, and four were non-compliant. The factors that affect the compliance to the SOP were based on the skills of the participants. Another factor identified was the way the standard operating procedure communicated to the human users on how to perform the ultrasound. Further training was therefore planned.

Abstract

This research identified evidence of knowledge and caring attitude among Sri Lankan nurses caring for dying patients; and identified the factors affecting nursing care for the dying in the eastern province of Sri Lanka. A quantitative cohort study design was used having questionnaires as the means of collecting the data. The purposive way of sampling selected 120 staff nurses employed in a government hospital as respondents who falls under the inclusion and exclusion criteria.There was significant evidence of caring attitude towards the dying (p = 0.005534) and knowledge on the end-of-life nursing care (p = 0.0004703) for the dying patients. Educational attainment (p = 0.050001), clinical experiences (p = 0.01499), age (p = 0.01061) and civil status (p = 0.001782) were factors affecting the knowledge and attitude of Sri Lankan nurses in delivering nursing care for the dying patients admitted to a government hospital.
