AbdElFattah, "Assessing validity of the adapted Arabic Paediatric Asthma Quality of Life Questionnaire among Egyptian children with asthma.", Eastern Mediterranean health journal = La revue de sante de la Mediterranee orientale = al-Majallah al-sihhiyah li-sharq al-mutawassit, vol. 16, issue 3, pp. 274-80, 2010 Mar. Abstract

The recent focus in asthma management is rendering children a better quality of life (QOL). Validity and reliability of an adapted Arabic translation of the Paediatric Asthma Quality of Life Questionnaire (PAQLQ-A) among Egyptians was assessed in a cohort of 103 asthmatic children aged 8-16 years. Discriminative validity of mean scores was significantly higher among mild asthmatics than those with moderate/severe asthma. Construct validity of domains was significantly negatively correlated with clinical severity score. Reliability and internal consistency were assessed using Cronbach alpha coefficient (alpha = 0.84). Reproducibility and responsiveness were high among both stable and unstable asthma patients. PAQLQ-A is valid and reliable for assessing QOL among Egyptian asthmatic children.

Abstract

INTRODUCTION AND HYPOTHESIS: Most vaginal births are associated with trauma to the perineum. The morbidity associated with perineal trauma can be significant, especially when it leads to third- and fourth-degree perineal tears. We hypothesized that antenatal perineal massage could decrease the incidence of perineal trauma, particularly severe perineal tears and other postpartum complications. METHODS: We searched four different databases from inception until August 2019 for the available trials. We included randomized controlled trials (RCTs) which assessed the effect of antenatal perineal massage (intervention group) versus control group (no antenatal perineal massage) in perineal trauma patients. Data were extracted from eligible studies and meta-analyzed using RevMan software. Primary outcomes were the risk of episiotomies and perineal tears. Secondary outcomes were perineal pain, second stage of labor duration, wound healing, anal incontinence, and Apgar scores at 1 and 5 min. RESULTS: Eleven RCTs with 3467 patients were analyzed. Women who received antenatal perineal massage had significantly lower incidence of episiotomies (RR = 0.79, 95% CI [0.72, 0.87], p < 0.001) and perineal tears (RR = 0.79, 95% CI [0.67, 0.94], p = 0.007), particularly the risk of third- and fourth-degree perineal tears (p = 0.03). Better wound healing and less perineal pain were evident in the antenatal perineal massage group. Antenatal perineal massage reduced the second stage of labor duration (p = 0.005) and anal incontinence (p = 0.003) with significant improvement in Apgar scores at 1 and 5 min (p = 0.01 and p = 0.02). CONCLUSIONS: Antenatal perineal massage is associated with a lower risk of severe perineal trauma and postpartum complications.

ABDELHALIM, H. S., M. A. Moharram, and E. H. ROZAIK, ANAEROBIC UP FLOW FLUIDIZED BED REACTOR PERFORMANCE AS A PRIMARY TREATMENT UNIT IN DOMESTIC WASTEWATER TREATMENT, , 2014. Abstract

ABSTRACT

The fluidized bed UASB performance was studied in this experiment as a primary unit the anaerobic unit the advantage of better generated sludge characteristics and smaller tank volume.
The reactor performance was investigated for the treatment of domestic wastewater with unexpected industrial water flows at different operational temperatures (14-25°C) and loading rates. For each temperature range the reactor performance was studied under different hydraulic loadings HRT (6, 4, 2.5 hours).
The best methane yield rate and COD total removal rate are 0.285 l/ g COD total and 70.82 % respectively at warm working temperature 19°C with OLR 7.76 Kg COD /m3/day and HRT 6h.
On the low temperature operation, the average COD removal of the reactor was 55.28 % and 50.33 % for HRT of 4 hours and 2.5 hours respectively. The methane production dropped to 0.1623 & 0.0988 L CH4 / g COD with average organic loading rate of 5.34 & 10 Kg COD /m3/day for HRT of 4 hours and 2.5 hours respectively.
The efficiencies of Total nitrogen removal ranged between (2.23-10.83) % with an apparent decrease during the low temperature high rate stages .Nitrite removal were in the range of (23.08 -77) % with up to the 2 mg/L in the effluent water when obtaining high organic loading and warm temperature. These results demonstrated that the domestic wastewater could be anaerobically treated in a fluidized bed UASB reactor with very low HRT reaching 2 .5 hours.
