Current status of biomedical waste management practices and barriers among private Jordanian dental clinics: A cross-sectional investigation of the capital Amman.

Biomedical waste management (BMWM) is vital in facilitating safe providing of healthcare. Developing countries suffer from the impact of mishandled biomedical waste (BMW) on the general public in addition to healthcare practitioners. Thus, this study aims to investigate the awareness and compliance of dental facilities to BMW regulations. Through a questionnaire designed as per the WHO guidelines on BMWM, we randomly recruited a total of 421 dental facilities representative of Jordan's capital. Mean BMWM practice scores were relatively high for the studied sample (0.748 ± 0.12). Nonetheless, while collection, transportation and storage standards were acceptable, those pertaining to segregation and disposal demonstrated lack of compliance to BMWM safety measures. An alarming number of participants dispose of infectious waste (40%), extracted teeth (48.5%), expired pharmaceuticals (44.4%), liquid chemicals (53.2%), X-ray films (35.0%) and solutions (48.7%) in the general trash or draining system. Such is attributed to either lack of resources, lack of proper equipment or poor awareness with BMWM guidelines. Moreover, it appears that location of the clinic (p < 0.001), occupation (p = 0.026) and presence of regulatory instructions (p = 0.048) were associated with higher BMWM scores. Overall, dental practitioners require proper training in terms of handling hazardous dental, chemical and radioactive wastes. Moreover, regulatory bodies should actively enforce regulations and monitoring, update current compliance legislations and subsidize eco-friendly practices.

The Effect of a Single Intravenous Corticosteroid Administration on Pain after Knee Arthroscopy: A Prospective, Double-Blind, Non-Randomized Controlled Clinical Trial.

BACKGROUND: Knee arthroscopy is a standard surgical procedure that is nowadays widely performed as day-case surgery. The aim of the study was to observe the effect of a single dose of intravenous corticosteroid on pain after undergoing knee arthroscopy for non-bony procedures. METHODS: A prospective, double-blind study design was adopted. Patients undergoing knee arthroscopy for non-bony procedures were prospectively assigned into two equal groups: control (those who were not given steroids) and treatment (those who were given eight milligrams of dexamethasone intravenously 15 min prior to the inflation of the tourniquet). The pain was assessed pre-operatively on admission and on the first post-operative day during the morning round in five different movements using a visual analogue scale (VAS). RESULTS: A total of 60 patients were included in the study. There was no significant difference in the pre-and post-operatively scores between both groups. The treatment group experienced a significant reduction in post-operative morphine requirements, with 80% of patients who did not receive dexamethasone requiring post-operative morphine compared to only 53.3% of patients who did (p = 0.027). CONCLUSIONS: Pre-operative intravenous administration of a single dose of dexamethasone may decrease opioid requirements for adequate pain control after knee arthroscopy.

Views of university students in Jordan towards Biobanking.

BACKGROUND: Biobanks are considered primary means+ of supporting contemporary research, in order to deliver personalized and precise diagnostics with public acceptance and participation as a cornerstone for their success. AIMS: This study aims to assess knowledge, perception, and attitudes towards biomedical research and biobanking among students at the University of Jordan. METHODOLOGY: An online questionnaire was designed, developed, and piloted. It was divided into 5 sections that included questions related to issues of biomedical research and biobanking as well as factors influencing the decision to participate. RESULTS: Responses from 435 students revealed that 52.9% previously heard of biobanks. There was an overwhelming acceptance for participation in biomedical, genetic, and biobanking research. A blood sample was the most preferred for donation. Protection of privacy, informed consent prior to donation, approval of an ethics committee, and trust towards researchers were the most important factors associated with willingness to participate. On the other hand, the vagueness of the type of research performed on the biospecimens and the unavailability of general research results to the donor had a negative connotation. There was no clear agreement on the type of informed consent preferred by students, but to be contacted and informed of research results was preferred by the majority. Students also preferred the disposal of biospecimens and information when deciding to withdraw from participation. CONCLUSION: There is strong enthusiasm among students to participate in biomedical research and biobanking with all rights reserved thus providing hope for a very promising future in Jordan.
