The Influence of Hearing on Posture

Maintaining upright posture requires integration of somatosensory, visual and vestibular information, and traditionally considered an automatic and effortless task. Recent research indicates that postural maintenance requires attention which interacts with other common tasks that share cognitive resources. This thesis investigates the influence of one such task, listening, on posture control and explores the novel idea that increased listening effort arising from hearing impairment uses extra attentional resources leaving less for posture control leading to an increased risk of positional or situational instability. A dual-task study to explore the relationship between listening and posture suggested that listening has a destabilizing effect on posture control. This effect was detected by mean velocity, a centre of pressure measure. To further understand this effect, the mechanisms underpins this relationship was studied using stabilogram diffusion analysis. The results suggested that open-loop and closed-loop strategies were utilised to maintain upright posture. This relationship was further investigated under simulated hearing loss conditions, and the results revealed increased postural sway and longer open-loop times before switching to closed-loop mechanisms. The deterioration of postural performance whilst listening may be explained by the idea that working memory has limited resource capacity to execute tasks, and that both tasks here requires attention and are competing for cognitive resources. Therefore, when the simulated hearing loss was introduced, it exacerbated this effect suggesting that performance was compromised due to the raised listening effort. It was concluded that mean velocity was sensitive to changes in postural sway resulted from performing a concurrent listening task. It was also concluded that stabilogram diffusion analysis would provide a comprehensive understanding of the postural strategies individuals adopted to maintain erect posture under normal and simulated hearing loss listening conditions

Two-Dimensional Materials for Terahertz Emission

The demand for ultrahigh-speed, lightweight, low-cost, and defect-tolerant electronic devices drives the industry to switch to terahertz (THz) technologies. The use of two-dimensional (2D) materials has massively increased in THz applications due to their appealing electronic and optoelectronic properties, including tunable bandgap, high carrier mobility, wideband optical absorption, and relatively short carrier lifetime. Several 2D-material-based emitters, modulators, and detectors have been fabricated and examined. In this context, considerable research has been going on for 2D-material-based THz emitting sources, including materials and device structure to understand the electronics and optoelectronics mechanisms occurring in the THz region. This chapter focuses on the 2D-material-based emitters with insights into the background, the physical principle of photoconductive THz emitters, the 2D materials’ properties, and the research trends in the fabrication and characterization of the THz sources based upon 2D materials

Water-Soluble Rhenium Phosphine Complexes Incorporating the Ph2C(X) Motif (X = O–, NH–): Structural and Cytotoxicity Studies

Reaction of [ReOCl3(PPh3)2] or [ReO2I(PPh3)2] with 2,2′-diphenylglycine (dpgH2) in refluxing ethanol afforded the air-stable complex [ReO(dpgH)(dpg)(PPh3)] (1). Treatment of [ReO(OEt)I2(PPh3)2] with 1,2,3-triaza-7-phosphaadamantane (PTA) afforded the complex [ReO(OEt)I2(PTA)2] (2). Reaction of [ReOI2(PTA)3] with dpgH2 led to the isolation of the complex [Re(NCPh2)I2(PTA)3]·0.5EtOH (3·0.5EtOH). A similar reaction but using [ReOX2(PTA)3] (X = Cl, Br) resulted in the analogous halide complexes [Re(NCPh2)Cl2(PTA)3]·2EtOH (4·2EtOH) and [Re(NCPh2)(PTA)3Br2]·1.6EtOH (5·1.6EtOH). Using benzilic acid (2,2′-diphenylglycolic acid, benzH) with 2 afforded the complex [ReO(benz)2(PTA)][PTAH]·EtOH (6·EtOH). The potential for the formation of complexes using radioisotopes with relatively short half-lives suitable for nuclear medicine applications by developing conditions for [Re(NCPh2)(dpg)I(PTA)3] (7)[ReO4]− in a 4 h time scale was investigated. A procedure for the technetium analog of complex [Re(NCPh2)I2(PTA)3] (3) from 99mTc[TcO4]− was then investigated. The molecular structures of 1–7 are reported; complexes 3–7 have been studied using in vitro cell assays (HeLa, HCT116, HT-29, and HEK 293) and were found to have IC50 values in the range of 29–1858 μM

“The Association between Waiting Time and Patient Satisfaction in Outpatient Clinics” at “King Abdullah Medical City, Makkah”

BACKGROUND: Patients have historically found lengthy wait times to be annoying, and this appears to be a consistent and important contributing factor in their unhappiness.  The timely, effective, and patient-centered delivery of high-quality healthcare is influenced by patient happiness, and patient satisfaction is linked to clinical outcomes, making it a key indicator for determining the quality of healthcare. Waiting time, which is a crucial component in determining service quality, could be a useful instrument for assessing patient satisfaction. It has been proven that waiting times and patient satisfaction have a significant inverse relationship.  “OBJECTIVE”: The goal of this examination is to recognize the association among to come time and patient pleasure and to identify predictor’s patient satisfaction and waiting time in outpatient clinics in a KAMC, Makkah SETTINGS/DESIGN: The project type is a descriptive-analytical research design. Undertaken at “King Abdullah Medical City, Makkah”. “SUBJECTS AND METHODS”: A sample of 499 patients was recruited. The investigator collected the socio demographic data from patients’ electronic /files, the other data included patient waiting time, and patient satisfaction score, which was collected from the hospital quality department and patient experience department during the period of 2021. RESULTS: The result shows that the remaining patients weren\u27t happy, but nearly half of them were. Participants\u27 satisfaction scores varied significantly according on their gender, age group, and type of visit. There is no statistical differences between satisfaction score with nationality and place of resident. The result also shows that by waiting time, the satisfaction rating varied dramatically. In addition, most of the participants who waited more than 20 minutes shows that they were dissatisfied. The test result also demonstrates that waiting time and satisfaction are related except consultation time it shows that no statistical relationship. Finally the result identified that age, gender and type of visit as significant predictors of patient satisfaction. CONCLUSION: The necessity of assessment should be the emphasis of healthcare organizations the patient’s satisfaction in relation with waiting time in outpatient department since doing so will give a rudimentary comprehension of the patient\u27s viewpoints on improving their satisfaction. This outcome can aid healthcare organizations in determining where they need to improve. In order to reduce outpatient waiting times, improve patient happiness, and determine the efficacy of interventions in healthcare settings, additional experimental research is necessary

Multiple sclerosis following bariatric surgery: A report of five cases

Multiple sclerosis (MS) is a debilitating chronic inflammatory demyelinating disease that affects the central nervous system. The underlying cause of multiple sclerosis is unknown, yet there are various predisposing factors. Currently, bariatric surgery is an increasingly common solution for obesity. It has been reported that bariatric procedures result in miscellaneous neurological complications. To the best of our knowledge, this is the first case series to report the occurrence of MS following bariatric surgery. Here we report the cases of five patients who were recruited for inclusion following neurological examination, complete cerebrospinal fluid (CSF) study, enhanced cranial as well as spinal cord magnetic resonance (MR) images. Diagnosis of multiple sclerosis was made based on McDonalds criteria (2010). All cases were diagnosed with relapsing-remitting form of multiple sclerosis (RRMS) after various types of bariatric surgeries

CONCOMITANT USE OF NON-STEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDS) WITH WARFARIN

Introduction: Oral anticoagulation with warfarin is the accepted technique for treatment and prophylaxis of thromboembolic diseases. Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most broadly administered medications to control musculoskeletal pain or inflammation. besides to their antiplatelet work, NSAIDs can influence the pharmacologic activity of warfarin through their immediate interaction. High protein binding and the cytochrome P450 (CYP)- dependent clearance systems of NSAIDs can influence the serum levels of warfarin. Aim of work: In this review, we will discuss whether using warfarin with NSAID has any effect on the pharmacokinetics and pharmacodynamics of both drugs. Methodology: We conducted this review using a comprehensive search of MEDLINE, PubMed, and EMBASE, January 1985, through February 2017. The following search terms were used: Non-steroidal anti-inflammatory drug mechanism, warfarin mechanism, adverse effects of NSAID, adverse effect of warfarin, NSAID-warfarin interaction Conclusions: Co-administration of NSAIDs and Warfarin is a topic of debate. However, there are reasons for concern. Some NSAIDs alter hemostasis and, when combined with warfarin, may lead to an increase in bleeding time. There is also a risk of increased hepatic and renal toxicity which complicates things further. Balancing the pros and cons of this drug combination should be carefully done on a case to case basis to avoid any negative consequences. Key words: NSAID, warfarin, Aspirin, drug-drug interaction, bleedin

Healthcare Administration Facilitating Neonatal Resuscitation Program Role Of Nursing, Midwifery, Clinical Laboratory And Radiological Teams In NRP

The purpose of this review was to investigate the level of knowledge that nurses and midwives, as well as the clinical laboratory and radiology team, have regarding neonatal resuscitation. Additionally, the review aimed to investigate the effect that education has on knowledge levels, as well as the role that healthcare administration plays in making the program accessible to healthcare providers. Based on the timing of events, data from real-life instances reveal that main resuscitation events, as recommended by the guidelines of the Neonatal Resuscitation Program, are frequently severely delayed. Taking into consideration the fact that the individuals who participated in the NRP practitioner-training course had completed the course within the past four to five years, it was seen that the knowledge points were pretty satisfactory
