Preemptive use of adjunctive IV lidocaine for enhanced recovery after abdominal hysterectomy for overweight and obese women: a prospective, randomized, double-blind, placebo-controlled study

Background: This investigation planned to evaluate the clinical results of adjunctive IV lidocaine bolus dose plus infusion for one hour after surgery in patients who underwent an abdominal hysterectomy in obese and overweight women.Methods: We performed a double-blind, placebo-controlled study, (ClinicalTrials.gov identifier: NC03748108), with patients undergoing abdominal hysterectomy divided into 2 groups: one group received intravenous lidocaine single bolus dose preoperatively and IV infusions till one hour after the surgical procedure, and the opposite received normal saline infusion (placebo). We assessed postoperative results, including pain scores rankings on a visual analog scale (VAS) in rest and movement, administration frequency of pethidine. Postoperative nausea and vomiting, the period of hospital stay (LOS), time to ambulate, and patient satisfaction at forty-eight hours had been evaluated. Chi-square test and Monte Carlo test have been used for comparison among groups.Results: There were 120 patients in our study. The visual analog scale (VAS), pain scores, length of hospital stay (LOS), and administration frequency of pethidine were significantly lower in the lidocaine group. The total amount of consumed pethidine was significantly lower in the lidocaine than the placebo group. There was a significant reduction in post-operative pain which was assessed by visual analog scale (VAS) after 2,4,8,12, and 24 hours either during movement or during rest in the lidocaine group compared to the placebo group, p=(0. 0001,0.0001,0.0001,0.0001 and 0.0001).Conclusions: The administration of adjuvant intravenous lidocaine infusion reduces pain during the postoperative period after abdominal hysterectomy, is associated with early recovery, decreased postoperative opioid analgesic requirement, and better patient satisfaction in overweight and obese women undergoing abdominal hysterectomy.

Serial changes in the serum levels of leptin, homocysteine, galectin-3, total phospholipids and hexosamines among patients undergoing coronary artery bypass grafting

AbstractBackgroundCoronary artery disease (CAD) is the most common cardiovascular disorder in adults. This study was performed to elucidate the role of active leptin, homocysteine, galectin-3, total phospholipids, total, bound, free hexosamines, free-to-bound hexosamines ratio in the pathogenesis of chronic myocardial ischemia and studying the effect of coronary artery bypass grafting (CABG) on their serum levels.MethodsA prospective case control study was carried out on 100 ischemic heart disease male patients undergoing elective CABG and 25 healthy males. Serum levels of total phospholipids, total and free hexosamines, were estimated using spectrophotometric methods, while, serum levels of active leptin, homocysteine and galectin-3 were estimated using ELISA assay kit.ResultsSignificant higher serum active leptin, homocysteine, galectin-3, free hexosamines and free to bound hexosamines ratio levels preoperatively when compared with the control group (p < 0.01 for all) with significant lowering of their serum levels following CABG (p < 0.01 for all) except for active leptin. Significant lower serum total phospholipids, total and bound hexosamines levels preoperatively when compared with the control group (p < 0.01 for all) with significant elevations in their serum levels following CABG (p < 0.01 for all).ConclusionsHigh active leptin, homocysteine, galectin-3, free and free to bound hexosamines ratio and low total phospholipids, total and bound hexosamines play an important role in the pathogenesis of myocardial ischemia. The serum levels of homocysteine, galectin-3, hexosamines and total phospholipids, but not active leptin are significantly lowered following CABG

Cobalt Oxide Nanoparticles/Graphene/Ionic Liquid CrystalModified Carbon Paste Electrochemical Sensor for Ultra-sensitiveDetermination of a Narcotic Drug

Purpose: Drug-abuse, namely morphine (MO) affects the metabolism of neurotransmitterssuch as dopamine (DA). Therefore, it is crucial to devise a sensitive sensing technique tosimultaneously determine both compounds in real samples.Methods: The fabrication of the sensor is based on in situ modification of a carbon paste (CP)electrode with cobalt oxide nanoparticles, graphene, and ionic liquid crystal in presence ofsodium dodecyl sulfate; CoGILCCP-SDS. The modified sensor is characterized using scanningelectron microscopy, electrochemical impedance spectroscopy and voltammetry measurements.Results: Electron transfer kinetics and analytical performance of the proposed sensor wereenhanced due to the synergistic role of all the modifiers. The simultaneous determination of MOand DA achieved low detection limits of 0.54 nmol L−1 and 0.25 nmol L−1, respectively. Besides,a carbon-based electrochemical sensor is fabricated for the nano-molar determination of MOin real samples and formulations. The sensor showed fouling resistance and anti-interferenceability in presence of other species in human fluids. The real sample analysis of MO wassuccessfully achieved with good recovery results in urine samples and pharmaceutical tablets.Linear dynamic range, sensitivity, detection limit and quantification limit of MO in urine were5 nmol L−1 to 0.6 μmol L−1, 6.19 μA/μmol L-1, 0.484 nmol L−1 and 1.61 nmol L−1, respectively.Conclusion: This sensor has great ability to be extended for electrochemical applications inassaying of many drugs

Quality of milk fat obtained from cows and buffaloes fed a diet supplemented with flaxseed or soybean oils

The experiment was carried out to evaluate the quality of anhydrous milk fat (AMF) of cows and buffaloes supplemented with flaxseed oil (FO), soybean oil (SO), or their mixture (FSO). Lactating crossbred cows and buffaloes were fed with control diet or with one of three supplements: 2% FO, 2% SO, and 2% FSO according to a double 4 x 4 Latin Square Design. The diets with FO, SO, or FSO reduced saturated FA, mainly C4:0, C14:0 and C16:0, while increased the unsaturated FA C18:1 and C18:2 in milk from cows and buffaloes. Cholesterol content decreased in cow's AMF while increased in buffalo's AMF when a diet supplemented with FO, SO, or FSO. The diet with SO or FSO increased the content of vitamin E in AMF obtained from cows (25.06 and 17.89 mg 100 g-1) and buffaloes (28.48 and 30.32 mg 100 g-1) compared with the control diet (11.02 and 15.68 mg 100 g-1), respectively, which correlated positively with scavenging activity for DPPH• (r2 = 0.66) and ABTS• (r2 = 0.67) radicals. Solid fat content (SFC) was high for cow’s AMF, with 58.12-60.37% at 5°C compared to that of buffalo's AMF, with 52.37-56.98%, but was low for cow's AMF at >15°C. Finally, supplementing a diet with vegetable oils, particularly SO, improves the quality of AMF; increases USFA/SFA ratio, vitamin E content, and antioxidant activitie

IL-10 Gene polymorphism and graft outcome in live-donor kidney transplantation

Background: The description of polymorphisms in many of the key immunoregulatory molecules involved in the rejection process has offered a possible explanation for the individual variation in susceptibility to rejection and differences in allograft survival independent of the many known contributory factors. The aim of this work is to study the impact of IL-10 cytokine gene polymorphism on renal transplant clinical course and outcome.Methods: This work studied 50 transplant recipients maintained on sirolimus based immunosuppression for IL-10 cytokine gene polymorphisms. After transplantation patients were divided into two groups. Group (A) patients (12 patients) received sirolimus, tacrolimus and steroid, while Group (B) patients (38 patients) received sirolimus, mycophenolate mofetil and steroid. Results were correlated with acute and chronic rejection episodes as well as graft and patient outcome.Results: In our study, we found no impact of IL-10 on incidence and degree of acute rejection episodes, incidence of chronic allograft nephropathy, pathological changes in protocol biopsies, graft function and graft and patient survivals.  Conclusion: From this work, we can conclude that the potential impact of IL-10 cytokine gene polymorphisms on renal transplant clinical course and outcome have shown no influence, and probably other genes rather than IL-10 could be involved as key molecules for graft function

Perspective Chapter: The Toxic Silver (Hg)

In the late 1950s, residents of a Japanese fishing village known as “Minamata” began falling ill and dying at an alarming rate. The Japanese authorities stated that methyl-mercury-rich seafood and shellfish caused the sickness. Burning fossil fuels represent ≈52.7% of Hg emissions. The majorities of mercury’s compounds are volatile and thus travel hundreds of miles with wind before being deposited on the earth’s surface. High acidity and dissolved organic carbon increase Hg-mobility in soil to enter the food chain. Additionally, Hg is taken up by areal plant parts via gas exchange. Mercury has no identified role in plants while exhibiting high affinity to form complexes with soft ligands such as sulfur and this consequently inactivates amino acids and sulfur-containing antioxidants. Long-term human exposure to Hg leads to neurotoxicity in children and adults, immunological, cardiac, and motor reproductive and genetic disorders. Accordingly, remediating contaminated soils has become an obligation. Mercury, like other potentially toxic elements, is not biodegradable, and therefore, its remediation should encompass either removal of Hg from soils or even its immobilization. This chapter discusses Hg’s chemical behavior, sources, health dangers, and soil remediation methods to lower Hg levels

Work stress, work-family conflict, and psychological distress among resort employees: a JD-R model and spillover theory perspectives

The hospitality industry is well-known for its challenging and high-pressure work settings. In this context, employees commonly face a multitude of stressors originating from their roles and job responsibilities, which can significantly impact their psychological wellbeing. Hence, based on the job demands-resources (JD-R) model and the spillover theory, this study aims to empirically explore the direct and indirect effect of work stress (assessed by role overload, ambiguity, and conflict) on psychological distress among frontline employees in 3- and 4-star Egyptian resorts while considering the mediating influence of work-family conflict (WFC). Four hypotheses were put to the test through the application of the PLS-SEM 4.0 version (4.0.9.9). Based on the findings from 563 frontline employees who participated in this research, the study supports the four hypotheses affirming that work-related stressors significantly contributed to employees' psychological distress. Further, the findings highlighted that these stressors significantly spill over into employees' family lives, generating conflicts between work and family roles. In addition, the results emphasized the significance of WFC as a contributing factor to employees' psychological distress. Finally, the study concluded that WFC partially mediates the link between work stress and employees' psychological distress. Based on these findings, some theoretical and practical implications for hospitality scholars, resort management, and policymakers were suggested to enhance the employees' wellbeing and mitigate psychological distress in this vital sector

Pathological, microscopic, and molecular diagnosis of paratuberculosis/John’s disease in naturally infected dromedary camel (Camelus dromedarius)

Background and Aim: Paratuberculosis (PTB) or John’s disease is a chronic disease of ruminants impeding the reproduction and productivity of the livestock sector worldwide. Since there is a lack of pathological studies explaining the nature and development of the disease in camels, this study aimed to highlight the anatomopathological changes of PTB in camels, which may help in verifying and validating some diagnostic tests used to detect the etiology of the disease in camel tissues. Materials and Methods: In August 2017, at Alselaa border’s Veterinary Clinic of Al Dhafra Region, Western Abu Dhabi, UAE, one imported culled she-camel of 2 years old was subjected to clinical, microscopic, and anatomopathological investigations along with real-time quantitative polymerase chain reaction (q-PCR) to confirm the infection and correlate between clinical signs and pathological lesions of the PTB in dromedary camels. Results: Clinically, typical clinical signs compliant with the pathognomonic gross and histologic lesions of PTB were seen in naturally infected dromedary camel. As presumptive diagnosis microscopically, acid-fast coccobacillus bacterium clumps were demonstrated in direct fecal smears as well as in scraped mucosal and crushed mesenteric lymph node films, and in histopathological sections prepared from a necropsied animal and stained by Ziehl-Neelsen stain. Free and intracellular acid-fast clump phagosomes were further confirmed as Mycobacterium avium subsp. paratuberculosis by q-PCR. Conclusion: Clinical signs and pathological lesions of paratuberculosis in a dromedary camel were found to be similar to those of the other susceptible hosts
