A single-centre investigator-blinded randomised parallel-group study protocol to investigate the influence of an acclimatisation appointment on children’s behaviour during N2O/O2 sedation as measured by psychological, behavioural and real-time physiological parameters

Aims and objectives To describe a study protocol of a randomised control trial (RCT) assessing the effectiveness, in reducing dental anxiety, of an acclimatising nitrous oxide sedation (N2O) session prior to actual dental treatment with N2O. Materials and methods A single-centre investigator-blinded parallel-group RCT conducted in a postgraduate dental hospital in Dubai, United Arab Emirates (UAE). Anxious children requiring N2O (aged 5–15 years) will be randomly assigned to; a study group: children who will have a preparatory N2O trial experience or; a control group: children who will only have N2O explained to them. Treatment with N2O for both groups will start at the second visit. The following outcomes will be recorded: completion of dental treatment, anxiety scores at baseline and after treatment (using the Modified Child Dental Anxiety Scale faces), behaviour of the child (using Frankl Rating Behaviour Scale) and the acquisition of real-time physiological anxiety-related parameters (using E4® electronic wrist devices). Results The data will be analysed statistically. Discussion There is a paucity of research regarding dental N2O acclimatising appointments. This RCT will supplement existing literature. Conclusions This RCT will report whether prior acclimatising of a child to N2O sedation is effective, or not, in improving dental treatment behaviour

Childhood Lead Exposure in the Palestinian Authority, Israel, and Jordan: Results from the Middle Eastern Regional Cooperation Project, 1996–2000

In the Middle East, the major sources of lead exposure have been leaded gasoline, lead-contaminated flour from traditional stone mills, focal exposures from small battery plants and smelters, and kohl (blue color) in cosmetics. In 1998–2000, we measured blood lead (PbB) levels in children 2–6 years of age in Israel, Jordan, and the Palestinian Authority (n = 1478), using a fingerstick method. Mean (peak; percentage > 10 μg/dL) PbB levels in Israel (n = 317), the West Bank (n = 344), Jordan (n = 382), and Gaza (n = 435) were 3.2 μg/dL (18.2; 2.2%), 4.2 μg/dL (25.7; 5.2%), 3.2 μg/dL (39.3; < 1%), and 8.6 μg/dL (> 80.0; 17.2%), respectively. High levels in Gaza were all among children living near a battery factory. The findings, taken together with data on time trends in lead emissions and in PbB in children in previous years, indicate the benefits from phasing out of leaded gasoline but state the case for further reductions and investigation of hot spots. The project demonstrated the benefits of regional cooperation in planning and carrying out a jointly designed project

Psychological Impact of COVID-19 Pandemic among Healthcare Personnel in United Arab Emirates

Given the magnitude of the COVID-19 pandemic, adverse psychological outcomes are expected to occur among healthcare personnel (HCPs). However, little is known about these outcomes within Ras al Khaimah, UAE. This study aims to assess the psychological impact of COVID-19 on healthcare personnel from different hospitals and clinics in Ras Al Khaimah (RAK), UAE. An online questionnaire was distributed to healthcare personnel within Ras al Khaimah, UAE, through an institutional email that enabled them to enroll in the study after giving informed consent. Likert scale was used to calculate the relation between demographic factors and 13 variables of psychological distress. An unpaired t-test was applied. This study shows that 31.7% of HCPs in RAK report moderate to high levels of anxiety due to concerns of potential workplace exposure, 41.6% are afraid of infecting their families and 13.1% find themselves feeling isolated from their families. Those who were younger than 45 years old, unmarried people and having more than two children were more likely to experience psychological distress than their counterparts. While the adverse psychological impact within this population is not as severe as what was noted in different populations in other countries, they must be addressed. It is important to ensure that HCPs have the appropriate physical and mental resources to persevere through similar stressful periods in the future

Blind channel equalization in GI-less OFDM systems using property restoral

We introduce a new low complexity equalizer for Orthogonal Frequency Division Multiplexing systems with virtual carriers. The proposed equalizer utilizes the existing redundancy in the frequency domain to completely eliminate the effects of inter-symbol-interference. We prove the usage of frequency domain redundancy is effective to extract the transmitted signals. © 2009 IEEE
