Compliance with and knowledge about diabetes guidelines among physicians and nurses in Palestine.

Abstract: Guidelines for the care of patients with diabetes mellitus are believed to improve clinical practice and patient care. This study aimed to analyse the pattern of diabetes care by physicians and nurses in primary care clinics in Palestine and their self-reported compliance with the local Palestinian guidelines. Questionnaires were used to collect data from 401 participants in 3 governorates in the West Bank. In total, 46.0% of participants knew about the existence of the Palestinian guidelines and about 60% believed these were partially used; 32.7% had received training on implementation of the guidelines. Multivariate analysis showed that training on the guidelines was the only factor significantly associated with self-reported compliance with guideline use. Respondents reported high commitment to the use of the guidelines, but their attitudes and behaviour varied with time constraints, availability of the guidelines, availability of laboratory tests and training on how to apply the guidelines.

Novel Acylethanolamide Derivatives That Modulate Body Weight through Enhancement of Hypothalamic Pro-Opiomelanocortin (POMC) and/or Decreased Neuropeptide Y (NPY)

Abstract: Newly synthesized acylethanolamide derivatives oleoyl-L-valinolamide (1), oleoyl-D-valinolamide (2), elaidoyl-L-valinolamide (3), elaidoyl-D-valinolamide (4) stearoyl-L-valinolamide (5), and palmitoyl-L-valinolamide (6) were investigated in mice as antiobesity compounds. Compounds 1, 2, 5, 6 significantly decreased body weight by 6.57% following eight injections of 1 mg/kg i.p. during 39 days, while 3 and 4 showed no such activity. Receptor binding indicated that no compound activated CB1, CB2, PPARα, or TRPV1 receptors. Hypothalamic RT-PCR showed that mRNA expression of the anorexigenic genes POMC and CART was up-regulated by 1, 2, 5 and 1, 2, respectively, while that of the orexigenic genes NPY and CaMKK2 was down-regulated by the respective compounds 1, 5, 6 and 1, 2, 5. Oleoyl-L-valinolamide enhances anorectic pathways and lead to decreased glucose levels, enhanced locomotor activity, and improved cognition. Effects of oleoyl-L-valinolamide on weight were dose-dependent, and it could be given orally. 1, 2, 4, 5 down-regulated FAAH mRNA expression.

West Nile Virus: Seroprevalence in Animals in Palestine and Israel

Abstract: West Nile virus (WNV) epidemiological situation in Israel and Palestine, due to their unique location, draws attention following to the global spread of West Nile fever (WNF). Although much information is available from Israel on clinical cases and prevalence of WNV, clinical cases are rarely reported in Palestine, and prevalence is not known. The objectives of this study were to determine WNV seroprevalence in various domestic animals in Palestine and to reevaluate current seroprevalence, force of infection, and risk factors for WNV exposure in horses in Israel. Sera samples were collected from 717 animals from Palestine and Israel (460 horses, 124 donkeys, 3 mules, 50 goats, 45 sheep, and 35 camels). Two hundred and ten horses were sampled twice. The level of WNV antibodies was determined using commercial Enzyme-linked Immunosorbent Assay (ELISA) Kit. Seroprevalence in equids was 73%. Seroprevalence in Israel (84.6%) was significantly higher than in Palestine (48.6%). Seroprevalence in horses (82.6%) was significantly higher than in donkeys and mules (39.3%). Multivariable statistical analysis showed that geographical area, landscape features (altitude), environmental factors (land surface temperature during the day [LSTD]), species, and age significantly influenced WNV seroprevalence. Fourteen of 95 (14.7%) sheep and goats and 14/35 camels (40%) sampled in Palestine were seropositive for WNV. Of the horses that were sampled twice, 82.8% were seropositive for WNV at the first sampling, and all remained seropositive. Three of the seronegative horses, all from Palestine, converted to positive when resampled (8.5%). The results indicate that domestic animals in Palestine were infected with WNV in the past, and the seroconversion indicates that WNV was circulating in Palestine in the summer of 2014. Control measures to prevent human infection should be implemented in Palestine. Anti WNV antibodies in domestic animals suggest that those species can be used as sentinels for WNV activity in areas where most horses are either seropositive or vaccinated.

Removal of amoxicillin and cefuroxime axetil by advanced membranes technology, activated carbon and micelle-clay complex.

Abstract: Two antibacterials, amoxicillin trihydrate and cefuroxime axetil spiked into wastewater were completely removed by sequential wastewater treatment plant's membranes, which included activated sludge, ultrafiltration (hollow fibre and spiral wound membranes with 100 and 20 kDa cut-offs), activated carbon column and reverse osmosis. Adsorption isotherms in synthetic water which employed activated carbon and micelle–clay complex (octadecyltrimethylammonium–montmorillonite) as adsorbents fitted the Langmuir equation. Qmax of 100 and 90.9 mg g–1, and K values of 0.158 and 0.229 L mg–1 were obtained for amoxicillin trihydrate using activated carbon and micelle–clay complex, respectively. Filtration of antibacterials in the ppm range, which yielded variable degrees of removal depending on the volumes passed and flow rates, was simulated and capacities for the ppb range were estimated. Stability study in pure water and wastewater revealed that amoxicillin was totally stable for one month when kept at 37°C, whereas...
