Non-closure of the peritoneum during open appendicectomy decreases postoperative analgesia requirement

Background: Acute appendicitis is considered the most common surgical emergency in both adults and children. Open rather than laparoscopic appendectomy is still the most commonly performed procedure. Objective: To assess the effect of non-closure of the peritoneum during appendectomy on postoperative pain and finally on the analgesia requirement. Patients and Methods: Two hundred patients underwent appendicectomy. The patients were divided into two equal groups; each had one hundred patients. Group 1 (control or closure Group) in which, the peritoneum is closed; in group 2 (study or non-closure Group), the peritoneum is left alone without closing it. Results: The mean pain score in the non-closure group was less compared to that in the closure group. A significant decrease in parenteral analgesia requirements was shown in the non-closure group compared to the closure group. Conclusion: Leaving the peritoneum not sutured during appendicectomy has a positive outcome on postoperative pain and decreases the requirement for analgesia

USING WATER INDICES (NDWI, MNDWI, NDMI, WRI AND AWEI) TO DETECT PHYSICAL AND CHEMICAL PARAMETERS BY APPLY REMOTE SENSING AND GIS TECHNIQUES

This study was undertaken by analyzing data from satellite image (Landsat-8 OLI) and geographical information system (GIS) to find the relationship between water parameters and water indices of spectral images. The main purpose of this research was to develop a model for the physical and chemical parameters of Gharraf stream in Iraq. The water parameters used in this study included: acidity (PH), Total Dissolved Solids (T.D.S), Alkalinity(ALK), Electrical Conductivity (E.C), Calcium(Ca), Chloride (CL), Sodium (Na), Sulfate (SO4), Potassium (k), Total suspended solid (T.S.S), Total Hardness (TH).Where the samples were taken to seventeen stations with two seasons and at the same time took a satellite image on 4/FEB, 11 / MAY.GIS techniques were used in the beginning to project the coordinates of seventeen stations along the stream in Landsat-8 satellite image for extract data. Then, these data are treated in SPSS software for purpose finding correlation and regression equations. Positive strong correlations between the reflectance of the satellite image and the water parameters in 4/FEB and 11/ MAY with five stations, helped to build six regression models. These models could be used to predict these six water parameters (PH, E.c, CL, SO4, Na and K) at any point along the stream in Iraq from the satellite image directly

Effect of Zn precursors on hydrogen storage in MWCNTs-ZnO nanocomposites

This research included studying and preparing the complex [Zn(DMB)Cl]2 from the reaction 1 M ratio of 2,6-dimethoxybenzoic acid ligand (DMB) with one molar ratio of aqueous zinc chloride in the presence of triethylamine. This complex was diagnosed by several techniques including FT-IR, 1H NMR, elemental analysis and molar conductivity. The MWCNTS-ZnO composite was prepared by reacting the complex [Zn(DMB)Cl]2 with carbon nanotubes using an ultrasound device. The novelty of this work is mainly based on the use of zinc acetate and [Zn(DMB)Cl]2 in the preparation of MWCNTS-ZnO(acetate) and MWCNTS-ZnO(complex) nanocomposites, respectively, in order to determine the importance of raw materials and their effects on the ability to store hydrogen. Thereafter, hydrogen storage was measured as a prospective study of the MWCNTS-ZnO composites. The study proves that the maximum H2 storage was 4.3 wt% H2 using MWCNTS-ZnO(complex) at a pressure of 85 bar and a temperature of 77 K. Therefore, the kinetic and thermodynamic calculations were made for this composite to complete the study. The enthalpy value was 0.8771 KJ/(mol H2), the entropy value was 4.7029 (J/mol H2.K), and the separation factor RF was 0.168148. However, the adsorption process was compatible with the pseudo-second order reaction with a value of R2 = 0.9341. Moreover, the measurement shows that the nanocomposite has the ability to reach the highest storage value in only 30 s at a pressure of 85 bar

Novel zinc-2,6- dimethoxybenzoic acid complex as useful precursor for the synthesis of MWCNTs-ZnO nano-inorganic composite

The production of nanomaterials from new sources is an important topic because the diversity of the raw materials provides a variety of properties for these materials, therefore, this study involved the synthesis and characterization of a zinc complex obtained by reacting 2,6-dimethoxybenzoic acid (DMB) with zinc chloride in the presence of triethylamine as a bulk base. The structure and coordination mode of the resulting zinc complex were determined through various techniques, including FTIR, 1H NMR, elemental analysis, and molar conductivity. The findings confirmed that the 2,6-dimethoxybenzoic acid ligand acts as a bidentate ligand, coordinating through both oxygen atoms of the carboxylic group, resulting in a complex of the type [Zn(DMB)Cl]2. This complex was then used as a precursor for the synthesis of a ZnO-MWCNTs nanocomposite using ultrasound waves. The synthesized nanocomposite was characterized using SEM and XRD techniques. The results revealed the formation of small spherical clusters around the carbon nanotubes, with an average size of the spherical nanostructures measuring 11.875 nm. Moreover, the incorporation of zinc oxide nanoparticles had a positive impact on increasing the diameter of the carbon nanotubes from 3.005 nm to 21.218 nm

Visual functioning and health-related quality of life in diabetic patients about to undergo anti-vascular endothelial growth factor treatment for sight-threatening macular edema

Purpose: To examine patient-reported outcome (PRO) in a selected group of Swedish patients about to receive anti-vascular endothelial growth factor (VEGF) treatment for diabetic macular edema (DME). Material and methods: In this cross-sectional study, 59 patients with diabetes mellitus, who regularly visited the outpatient eye-clinics, were included. Sociodemographic and clinical data were collected and the patients completed PRO measures before starting anti-VEGF treatment. PRO measures assessed eye-specific outcomes (NEI-VFQ-25) and generic health-related quality of life (SF-36). Results: The participants consisted of 30 men and 29 women (mean age, 68.5 years); 54 (92%) patients had type 2 diabetes; 5 (9%) patients had moderate or severe visual impairment; 28 (47%) were classified as having mild visual impairment. Some of the patients reported overall problems in their daily lives, such as with social relationships, as well as problems with impaired sight as a result of reduced distance vision. Conclusions: Further studies are needed to investigate PRO factors related to low perceived general health in this patient population. It is important to increase our understanding of such underlying mechanisms to promote improvements in the quality of patient care

Gleason grade accuracy of transperineal and transrectal prostate biopsies in MRI-naïve patients

PURPOSE Accurate assessment of Gleason grade is essential to guiding prostate cancer management. Not all healthcare systems have universal access to prostate MRI. We investigated whether transperineal (TP) prostate biopsies provide more accurate Gleason grading than transrectal (TR) biopsies in MRI-naïve patients. METHODS Consecutive patients undergoing TP and TR systematic prostate needle biopsies from 2011 to 2018 were analysed. Patients who underwent radical prostatectomy (RP) within 180 days of biopsies were included. Patients undergoing MRI prior to biopsies were excluded. Pathological concordance, incidence of Gleason upgrading, and correlation coefficients among biopsies and RP Gleason grade were compared. A sub-analysis for concordance in anterior prostate tumours was conducted. RESULTS 262 patients were included (112 TP; 150 TR), the median age was 63 years, and median time from biopsy to RP was 68 days. Concordance with RP histology for TP was 65% compared to 49% for TR (p = 0.011). Biopsy technique predicted RP concordance independent of the number of cores. Gleason upgrading occurred following 24% of TP versus 33% of TR biopsies. In anterior and apical tumours, upgrading occurred in 19% of TP biopsies and 38% of TR biopsies (p = 0.027). CONCLUSION This study suggests TP approach to prostate biopsies result in improved histological grade accuracy in men whom MRI is not available, even after controlling for number of cores. TP approach also resulted in less upgrading for lesions in the anterior and apical prostate compared to TR
