Psychobehavioural responses to the 2014 Middle East respiratory syndrome-novel corona virus (MERS CoV) among adults in two shopping malls in Jeddah, western Saudi Arabia.

Sporadic cases of Middle East respiratory syndrome caused by a novel corona virus (MERS-CoV) were first detected in Saudi Arabia in June 2012. The number of cases was highest during April and May 2014. To assess determinants of psychobehavioural responses among the general population in Jeddah, western Saudi Arabia, a cross-sectional survey was conducted at the end of June 2014. Data included sociodemographic characteristics, level of anxiety, protective measures and social avoidance responses. A total of 358 participants completed the questionnaire; 58.4% were female, and the age range was 18-72 years. None of the participants was diagnosed with MERS-CoV. More than half (57.7%) recorded a moderate anxiety score using a visual analogue scale. Anxiety level was significantly associated with increased perception of susceptibility to infection and social avoidance behaviours related to travel and being in public places.

Des cas sporadiques d'infection par le coronavirus du syndrome respiratoire du Moyen-Orient [MERS-CoV] ont été détectés pour la première fois en Arabie saoudite en juin 2012. Le nombre de cas le plus élevé a été observé en avril et mai 2014. Afin de mesurer les déterminants des réactions psycho-comportementales de la population générale de Djeddah, dans la partie occidentale de l'Arabie saoudite, une étude transversale a été conduite fin juin 2014. Les données incluaient les caractéristiques socio-démographiques, le niveau d'anxiété, les mesures de protection et la mise en place de mesures d'éviction sociale. Un total de 358 participants ont rempli le questionnaire, dont 58,4% de femmes, les âges étant compris entre 18 et 72 ans. Le MERS-CoV n'a été diagnostiqué chez aucun patient. Plus de la moitié [57,7%] a rapporté un score d'anxiété modéré en se basant sur une échelle visuelle analogue. Le niveau d'anxiété était associé de façon significative à une perception augmentée de sensibilité à l'infection et au phénomène d'éviction sociale lié à la possibilité de voyager ou de se rendre dans les lieux publics

Evaluation of an educational intervention for farming families to protect their children from pesticide exposure.

A culturally appropriate educational intervention was developed and directed towards farming families in Menoufia governorate, Egypt, to improve their knowledge and practices in protecting their children from exposure to pesticides. Parents were randomly assigned to either a lecture or videotape training group. Ability to recall information or improve practices among parents was evaluated in 3 sessions: pretraining and 2 weeks and 1 month after training. Knowledge and practice scores after training of younger and more educated participants were significantly higher than older, less educated participants. Knowledge and practice performance of the videotape group was better than the lecture group and in both groups the improvement of knowledge scores after training was significantly higher than that of practice scores.

Neurobehavioral effects among inhabitants around mobile phone base stations.

BACKGROUND: There is a general concern on the possible hazardous health effects of exposure to radiofrequency electromagnetic radiations (RFR) emitted from mobile phone base station antennas on the human nervous system. AIM: To identify the possible neurobehavioral deficits among inhabitants living nearby mobile phone base stations. METHODS: A cross-sectional study was conducted on (85) inhabitants living nearby the first mobile phone station antenna in Menoufiya governorate, Egypt, 37 are living in a building under the station antenna while 48 opposite the station. A control group (80) participants were matched with the exposed for age, sex, occupation and educational level. All participants completed a structured questionnaire containing: personal, educational and medical histories; general and neurological examinations; neurobehavioral test battery (NBTB) [involving tests for visuomotor speed, problem solving, attention and memory]; in addition to Eysenck personality questionnaire (EPQ). RESULTS: The prevalence of neuropsychiatric complaints as headache (23.5%), memory changes (28.2%), dizziness (18.8%), tremors (9.4%), depressive symptoms (21.7%), and sleep disturbance (23.5%) were significantly higher among exposed inhabitants than controls: (10%), (5%), (5%), (0%), (8.8%) and (10%), respectively (P<0.05). The NBTB indicated that the exposed inhabitants exhibited a significantly lower performance than controls in one of the tests of attention and short-term auditory memory [Paced Auditory Serial Addition Test (PASAT)]. Also, the inhabitants opposite the station exhibited a lower performance in the problem solving test (block design) than those under the station. All inhabitants exhibited a better performance in the two tests of visuomotor speed (Digit symbol and Trailmaking B) and one test of attention (Trailmaking A) than controls. The last available measures of RFR emitted from the first mobile phone base station antennas in Menoufiya governorate were less than the allowable standard level. CONCLUSIONS AND RECOMMENDATIONS: Inhabitants living nearby mobile phone base stations are at risk for developing neuropsychiatric problems and some changes in the performance of neurobehavioral functions either by facilitation or inhibition. So, revision of standard guidelines for public exposure to RER from mobile phone base station antennas and using of NBTB for regular assessment and early detection of biological effects among inhabitants around the stations are recommended.

Neurobehavioural effects among workers occupationally exposed to organophosphorous pesticides.

AIMS: To identify neurobehavioural deficits among workers exposed to organophosphorous (OP) pesticides in their occupation. METHODS: This study was conducted during the period when pesticides were applied to cotton crops in the fields in Menoufiya Governorate, Egypt. Fifty two occupationally exposed male workers were compared to 50 unexposed male controls who were similar in age, socioeconomic class, and years of education (> or =12 years). All participants completed a questionnaire (assessing personal, occupational, and medical histories), general and neurological clinical examination, neurobehavioural test battery (including tests for verbal abstraction, problem solving, attention, memory, and visuomotor speed), personality assessment, and serological analysis for serum acetylcholinesterase. RESULTS: After correcting for confounders of age and education, the exposed participants exhibited significantly lower performance than controls on six neurobehavioural tests (Similarities, Digit Symbol, Trailmaking part A and B, Letter Cancellation, Digit Span, and Benton Visual Retention). A longer duration of work with pesticides was associated with lower performance on most neurobehavioural tests after adjusting for multiple comparisons. Although serum acetylcholinesterase was significantly lower in the exposed than the control participants, it was not significantly correlated with either neurobehavioural performance or neurological abnormalities. CONCLUSIONS: Occupational exposure to OP pesticides was associated with deficits in a wider array of neurobehavioural functions than previously reported, perhaps because of higher exposure in this population. Moderate chronic OP exposure may not only affect visuomotor speed as reported previously, but also verbal abstraction, attention, and memory.

[Dose dependence of reproductive lethal cell damage after X-ray irradiation or exposition to adriamycin at low doses (author's transl)]. / Dosisabhängigkeit reproduktiv letaler Zellschäden nach Röntgenbestrahlung oder Adriamycin-Exposition mit niedrigen Dosen.

The effect exerted by X-rays, adriamycin and combined adriamycin and X-ray exposition on the median colony size differences (MCD) on synchronized or partially synchronized hypotetraploid CHO-T71 fibroblasts proves that the MCD method is much more sensible in low dose regions than the normally used colony survival test. In dose regions lower than 1 Gy, the MCD shows a linear dependence on the radiation dose. As compared to the effect exerted by the cytostatic drug alone, the combined effect of adriamycin and X-rays shows a dose factor of 0,4 for the logarithmically rising scope of MCD. The possible reduction of adriamycin doses applied hitherto together with an additional irradiation provides a possibility to diminish toxic side effects for the patient and to preserve the local therapeutic effect. The authors underline the suitability of the MCD method for delicate biologic measurements on human cells in order to replace expensive experimentation on animals effected in order to test the individual efficacy of therapeutic combinations of cytostatic drugs and to ameliorate the demonstration of teratogenic and carcinogenic substances and substances with other toxic effects at low active ingredient concentrations.
