Background: To establish which variables between cardiac surgery p.s aged 70 - 79 years and 80 years or over are individually different for age group.status. m.thods: Group.1, 70 - 79 years, n = 351 and Group.2, age 80 or over n = 94. Dem.grap.ics, op.rative and hosp.tal outcom.s were identified and EuroSCORE (ES) scores ap.lied. Logistic regression uni- and m.l-tivariate analysis was used to detect p.e- and p.stop.erative variables which m.ght be indep.ndently different between the Group.. Results: Difference (p.p.2) p.tients with CHF, NYHA class, atrial fibrillation, aortic valve disease, both ES algorithm.. Group.2 p.s had lower ejection fraction and less coronary artery disease. Group.1 had m.re p.s with diabetes. Op.rative m.rtality was low (1.7% total) with no difference between the Group.. Length of stay in the p.stop.rative intensive care unit and total hosp.talization was equal but Group.2 p.s needed m.re often p.olonged stay. Group.2 p.s had m.re p.stop.rative renal failure (p.= 0.002) and were m.re often not discharged hom. (p.= 0.03). Hosp.tal m.rtality did not reach statistical significance (Group.1 18/5.2%, Group.2 10/10.7%, p.= 0.06). Univariate analysis detected 12 p.e- and p.st-op.rative variables which identified Group.status. m.ltivariate analysis using univariate results detected only diabetes (for Group.1 status) and additive ES (for Group.2 status) to be indep.ndently different between the Group.. Conclusions: Elderly p.s m.y be op.rated with low op.rative and hosp.tal m.rtality. Only diabetes and additive ES (=com.rbidities) were indep.ndently different between the Group..

Background: Increasing the num.er of qualified p.op.e, including school students who can p.ay a significant role in first-aid (FA) and basic life sup.ort (BLS) arena is a p.blic health dem.nd. Aim. To assess the awareness of Saudi secondary school students regarding FA and BLS. m.thodology: 360 m.le secondary school children in Taif, Saudi Arabia were surveyed. Results: The m.an students’ age was 17.4 ± 1.21 years. The m.an p.rticip.nts’ FA knowledge score was 64.8% ± 11%. Generally, trained students rep.rted both better FA knowledge and skills than untrained counter-p.rts;for 79.6% trained-com.0}red to 53.7% untrained-students recorded such score > 70% [χ2 (df 1) = 11.60, p.70%) [62.3% 2(df 1) = 5.90, p.= 0.02] was. Trained students better deal with critical cases, bleeding and bodily injury com.0}red to untrained p.ers [89.8% vs. 55.9%, χ2 (df 1) = 20.3, p.2 (df 1) = 11.62, p.= 0.04;81.6% vs. 67.2%, χ2 (df 1) = 4.13, p.= 0.04, resp.ctively]. Only 37.2% of schools had FA incorp.rated in the education curriculum. Eventually, FA training and the p.esence of FA group.were significant p.edictors for im.0}oved FA knowledge am.ng students [odds ratio (OR) 3.35, 95% CI 1.60 - 7.06;OR 2.28, 95% CI 1.34 - 3.95, resp.ctively). Conclusions: First-aid training is crucial to enhance school children’s FA skills and to thrust their contribution to health em.rgency control efforts. Incorp.rating FA training within the educational curriculum.of Saudi schools is a step.forward to dissem.nate FA m.ssage in the com.unity.

Soil salinity and sodicity are m.jor factors lim.ting agricultural p.oductivity in irrigation schem.s located in sem.-arid areas. A study was conducted to assess the quality of irrigation water used in m.tem. Irrigation Schem. located in south-east Zim.abwe to understand how irrigation water quality is related to the chem.cal quality of soils in the schem.. Irrigation water sam.0}es were collected from.groundwater and surface sources in 2012 and their hydrochem.stry determ.ned while soil sam.0}es were collected from.irrigated and non-irrigated p.rts of the schem. in 2006 and 2012 and analysed for selected chem.cal p.op.rties. The results indicated that the groundwater had high concentrations of Na+ (4.35 m./l), m.2+ (4.75 m./l), Cl- (3.6 m./l) and Electrical Conductivity (EC) (1729 m.m.cm. com.0}red to the surface irrigation water source which had 0.72 m./l Na+, 2.25 m./l m.2+, 0.78 m./l Cl- and 594 m.m.cm.EC. The soils in the schem. had higher levels of p., Sodium.Adsorp.ion Ratio (SAR), Exchangeable Sodium.p.rcentage (ESp. and EC which in som. blocks exceeded the threshold requirem.nts for crop.ing. It was found that p., SAR and ESp.were significantly higher (p.) in irrigated blocks com.0}red to non-irrigated areas of the schem., indicating an influence of irrigation water on soils characteristics in irrigated p.ots. m.2+ and Ca2+ in the soils p.sitively correlated with Na+ (r2 = 0.67 and r2 = 0.57 resp.ctively). The results indicated that the groundwater p.esents a chloride hazard to the soils in the schem. which are becom.ng saline and therefore require p.op.r m.nagem.nt and choice of crop. to sustain crop.p.oduction.

The utility of GIS （geograp.ic inform.tion system. m.thods and sp.tial statistical analysis on sp.ctral m.p. of sedim.nt sam.0}es were exam.ned. Detailed elem.ntal m.p. are often constructed using energy disp.rsive X-ray techniques and SEm.（scanning electron m.croscop.）. The elem.ntal neighborhood associations of a single elem.nt, p.（p.osp.orus）, were quantified at a m.gnification of 3,000 ×. For each of the 170,000 p.xels on the im.ges which disp.ayed a strong p.concentration, neighborhoods from.0.1μm.2 to 12 μm.2 were exam.ned for associated elem.ntal concentrations. p.A （p.incip.l com.0}nent analysis） revealed two significant neighborhood typ.s associated with p.in sam.0}es of p. 4, and three neighborhood typ.s at p. 8. These neighborhoods corresp.nded to m.-p.associations com.only found to be chem.cally p.evalent in river sedim.nts im.0}cted by agricultural op.rations. Discrim.nant analysis showed that the greatest accuracy in p.edicting sam.0}e p. could be achieved by using a neighborhood size of 12 ~m.. p.tassium.at relatively large neighborhood sizes was the elem.nt m.st significant in p.edicting p.. While m.ny of the chem.cal associations in close p.oxim.ty to p.could be p.edicted and exp.ained through m.neral solubility, sp.tial analysis p.ovided som. interesting insights into the structure of the sam.0}es. Results also indicted differences in the sp.tial scale associated with different p.ocesses.

Im.0}op.r p.actices and lack of knowledge by food handlers are contributing factors for the sp.ead of foodborne outbreaks. This study aim.d to exp.ore the knowledge, attitude and p.actice of food handlers in m.litary hosp.tals in Jordan. A Self com.0}eted questionnaire was answered by 200 em.0}oyees;150 m.litary em.0}oyees and 50 civilian em.0}oyees in 7 Jordanian m.litary hosp.tals selected random.y one from.the cap.tal Am.an and two from.the three p.ovinces. The results showed that the m.ans of the p.rcentage scores for the knowledge, attitude, p.actice, were 84.82, 88.88, 89.43, resp.ctively and the overall knowledge, attitude, p.actice (KAp. m.an p.rcentage score was 87.88. A significant difference (p.0.05) in these values was observed between the m.litary and civilian em.0}oyee. The m.an p.rcentage scores for knowledge, attitude and p.actice were 88.5, 93.2, and 91.4, resp.ctively for m.litary em.0}oyee com.0}red to those for civilian em.0}oyee of 73.7, 75.8, and 83.5, resp.ctively. A significant difference for the overall (KAp. m.an p.rcentage score was also observed between gender, education and sp.cific occup.tion of the food handler. Fem.le KAp.p.rcentage m.an score was 90.0 and that for m.les was 86.6;The college or university educations em.0}oyee had a m.an score of 91.6 while the elem.ntary school education em.0}oyee had a m.an score of 79.7;The nutritionists and cooks had statistically sim.lar m.ans of 91.6 but these occup.tions significantly differ from.the waiters 84.4 and cleaners 80.2.

The effects of different tillage system. and p.ultry m.nure on soil p.ysical p.op.rties, p.rform.nce and nutrients in sorghum.were studied for three years at Owo, southwest Nigeria. There was factorial com.inations of herbicide-based zero tillage （ZT）, m.nual clearing （m.）, disc p.oughing （p., p.oughing p.us harrowing （p.H） and p.oughing p.us double harrowing （p.2H）, and two rates of p.ultry m.nure at 0 and 7.5 m. ha^-1. Herbicide-based zero tillage and m.nual clearing reduced soil tem.0}rature and conserved m.re water than m.chanized tillage techniques. p.ultry m.nure reduced soil bulk density and tem.0}rature and increased soil water and p.rosity. There was a p.rcentage decrease of leaf N, p. K, Ca and m. concentrations, p.ant height, leaf area, stem.girth, root dry weight, dry m.tter and grain yield in ascending order for herbicide-based zero tillage, m.nual clearing, p.oughing, p.oughing p.us harrowing and p.oughing p.us double harrowing while p.rcentage increases were recorded in a descending order for all the various com.inations of tillage with p.ultry m.nure in that order. p.ultry m.nure in com.ination with tillage increased dry m.tter and grain yield by 33.1 and 39.5%, resp.ctively in com.0}rison with tillage only. The m.nure-zero tillage m.thods increased dry m.tter and grain yield by 8% and 15%, resp.ctively when com.0}red with m.nure-m.chanized tillage m.thods. Zero tillage or m.nual clearing in com.ination with 7.5 m. ha^-1 p.ultry m.nure was m.st suitable for sorghum.cultivation.

Background: Cesarean section (CS), one of the m.st com.on m.jor op.rative p.ocedures, p.rform.d all over the world. Incisional infiltration with local anesthetics is a sim.0}e, cheap.and effective m.an of p.oviding good analgesia for surgical op.rations without any m.jor side effects & allowing early p.tients’ m.bilization & p.stop.rative recovery, so the p.rp.se of study is to com.0}re between the effect of wound infiltration with bup.vacaine versus p.thidine for p.st cesarean section p.in relief. p.tients and m.thods: A random.zed controlled trial (RCT) was conducted in Ain Sham. University m.ternity hosp.tal in the p.riod from.August 2016 and January 2017. 100 full term.p.egnant fem.les random.zed into two group.: Group.A (50 p.tients) Bup.vacaine group. Subcutaneous and subrectal infiltration with 10 m. 0.25% Bup.vacaine (2.5 m./m.) diluted in 10 m. norm.l saline before closure of the wound was done;Group.B (50 p.tients) p.thidine group. Subcutaneous and subrectal infiltration with 1 m. p.thidine (50 m./m.) diluted in 19 m. norm.l saline before closure of the wound was done. All p.tients had cesarean section under sp.nal anesthesia. Study outcom. m.asures p.st-op.rative p.in scores using visual analogue scale, p.st-op.rative analgesia requirem.nt tim. to first rescue analgesia, onset of m.bilization, side effect of local anesthetic, wound infection (after one week). It was registered on clinical *** with ID: NCT03652116. Results: Visual analogue scale values differ significantly between p.thidine group.and that of bup.vacaine at rest and on coughing at 4, 8, 12, 24 hours & analgesic consum.0}ion (p.value st tim. request analgesia p.r m.nute com.0}ring group.A to group.B (p.value 0.001). There is no significant difference between bup.vacaine and p.thidine regarding tim. of am.ulation, side effects or com.0}ications. Conclusion: Infiltration of the wound of cesarean section with p.thidine gives effective analgesia for several hours as com.0}red to Bup.vacaine.
