PERCEIVED NEW RISKS TO CONSTRUCTION WORKERS IN KUWAIT DUE TO RISING TEMPERATURES
This study aimed to examine the risks construction workers in Kuwait face due to increasing temperatures. The environmental conditions for construction workers include working in hot and humid environments, wearing protective clothing, and performing hard physical work. These aspects place them at an increased risk for occupational heat stress. The health impacts of occupational heat exposure for construction workers are heat-related diseases, occupational accidents/ injuries, urological diseases, dysfunctional reproductive system, reduced mental health and cognitive functioning, vision and eye problems, and death. Heat exposure affects workers\u27 health through heat-related illnesses, including heavy sweating, dizziness, muscle pain, fatigue, skin itchiness, and headache. Heat exposure also has various direct and indirect social implications for construction workers. It leads to family problems, workplace issues with co-workers and managers, reduced income, lack of basic amenities, reduced capability, and reduced productivity. One significant preventive measure for heat stress is providing training and education to workers on identifying heat stress signs and assessing and monitoring themselves and fellow workers while working in hot environments
Level of Implementation and Beliefs about Evidence-Based Practice among Respiratory Therapists in Clinical Setting in Saudi Arabia.
BACKGROUND: Evidenced-based practice (EBP) is applying or translating research findings in our daily patient care practices and clinical decision-making. EBP also involves integrating the best available evidence with clinical knowledge and expertise, while considering patients’ unique needs and personal preferences. Since the role of RTs has increased, the importance of choosing the most effective treatment available is vital. Therefore, it is essential to evaluate RTs\u27 EBP beliefs and their implementation level and obtain important information about their daily clinical practice. PURPOSE: The purpose of this study was to measure the level of implementation, describe beliefs about EBP among respiratory therapists in the clinical setting in Saudi Arabia. METHODS: The study utilized an online, cross-sectional survey with 34 questions administered to a convenience sample of RTs in Saudi Arabia. The survey is divided into three sections: belief and implementation, and demographics questions. Data were analyzed using descriptive statistics and one-way ANOVA tests. A significance level was set at 0.05. All analyses were performed in SPSS version 26. RESULTS: The total sample consisted of 49 respiratory therapists consisting of three experience levels: less than 5 years (n=38, 77.55%), 5 to 10 years (n=6, 12.24%), and more than 10 years (n=5, 10.20%). The majority of the respondents were males (57%, n=28), while the females comprised (40% n=20). Most of the respondents in the study are between 25 and 30 years old (59% n=29), under 25 years (32% n=16), and over 35 years old (8% n=4) There were no statistically significant differences between male and female respondents or years of experience in the belief or implementation scales. CONCLUSION: In conclusion, the respiratory therapists\u27 community in Saudi Arabia reported their positive beliefs about EBP, but most of them did not frequently implement it in their daily clinical practice. Further research is required due to a lack of literature on evidence-based practice in respiratory therapy, and to assess the correlates of negative EBP\u27 implementation levels among RTs in Saudi Arabi
Role of Antiviral Drugs in Management of Mild and Moderate Coronavirus Disease-19: A Systematic Review
This study was conducted to determine the objective role of antiviral drugs such as arbidol, lopinavir/ritonavir, and others in improving clinical symptoms, decreasing duration of hospitalization, and decreasing duration of viral shedding in patients with mild and moderate COVID-19 infection. A systematic literature search was carried out on Google Scholar and PubMed databases, using the keywords “COVID-19”, “Antiviral”, “Treatment”, and “Symptomatic” in various combinations. Observational studies, cohort and case control studies, and clinical trials published in English with full-text available were included in the study. Data extraction was carried out from selected studies, and all statistical analysis for the study was carried out using Microsoft Excel. The key outcomes studied were time to negative PCR, duration of clinical stay, time to clinical improvement, and occurrence of adverse events. Seven studies were selected for final review after rigorous selection process. Data of total 4734 participants was analyzed, the majority of which were females (n=2810, 59.3%). The majority of participants had mild disease (n=4197, 88.65%). Average time for negative RT-PCR in the included treatment groups was 13.5 days, whereas the average duration of hospitalization was 14.9 days for the treatment groups. Adverse reactions such as ECG changes, gastrointestinal symptoms, secondary bacterial infections, and hepatic and renal dysfunction were scarcely reported in the included studies. There is no clear benefit in terms of duration of hospitalization and time to negative PCR with the use of various antiviral regimens in mild disease; however, these drugs did play a role in limiting disease progression in the participant population. Pending further evidence, the use of these drugs for the management of COVID-19 is not recommend in patients with mild disease
Epigenetic-Mediated Antimicrobial Resistance:Host versus Pathogen Epigenetic Alterations
Since the discovery of antibiotics, humans have been benefiting from them by decreasing the morbidity and mortality associated with bacterial infections. However, in the past few decades, misuse of antibiotics has led to the emergence of bacterial infections resistant to multiple drugs, a significant health concern. Bacteria exposed to inappropriate levels of antibiotics lead to several genetic changes, enabling them to survive in the host and become more resistant. Despite the understanding and targeting of genetic-based biochemical changes in the bacteria, the increasing levels of antibiotic resistance are not under control. Many reports hint at the role of epigenetic modifications in the bacterial genome and host epigenetic reprogramming due to interaction with resistant pathogens. Epigenetic changes, such as the DNA-methylation-based regulation of bacterial mutation rates or bacteria-induced histone modification in human epithelial cells, facilitate its long-term survival. In this review article, epigenetic changes leading to the development of antibiotic resistance in clinically relevant bacteria are discussed. Additionally, recent lines of evidence focusing on human host epigenetic changes due to the human–pathogen interactions are presented. As genetic mechanisms cannot explain the transient nature of antimicrobial resistance, we believe that epigenetics may provide new frontiers in antimicrobial discovery.</p

The Benign Prostatic Hyperplasia and Its Aetiologies
This study aimed at investigating the Benign Prostatic Hyperplasia and Its Aetiologies, therefore th prostatic hyperplasia predominantly involves the stromal compartment of the gland and affects more than 70% of men of 70 years or older with or without obstructive symptoms of benign prostatic hyperplasia. A consensus view is emerging concerning the factors and control systems that modulate cell proliferation and connective tissue biology in the prostate. The purpose of this review is to discuss some of the recent work contributing to the latter in the context of the aetiology of benign prostatic hyperplasia. The current study also reviews the most important findings regarding the key mechanisms involved in the pathophysiology of BPH. The study concluded that although the pathogenesis of BPH is not yet fully understood, several mechanisms seem to be involved in the development and progression of the disease. These mainly include systemic and local hormonal and vascular alterations as well as prostatic inflammation that would stimulate cellular proliferation
A cross-sectional study on the flood emergency preparedness among healthcare providers in Saudi Arabia
This study used a descriptive cross-sectional methodology to measure healthcare workers’ knowledge, attitudes, perceptions, and willingness to respond to a flood scenario in Saudi Arabia. A validated survey was distributed to collect data using a convenience sampling technique through multiple social media platforms. A total of 227 participants were included in this study: 52% of them were aged between 26 to 34 years, 74% were residents from Riyadh, and 52.4% worked in nursing divisions. A significant number of respondents (73.2%) had positive perceptions towards their hospitals’ ability to provide an effective response to a flood, 89% were willing to report to work following a flood, and 90% of participants reported the need to develop both guidelines and training for flood disaster preparedness. Preparation and successful flood mitigation in the hospital setting requires staff that have both knowledge and training in emergency management. One way to obtain such readiness is through competency-based training, including both table-top and full-scale live exercises. Although the willingness to respond to such a flooding emergency was high among staff, the development of guidelines and educational programs is needed in order to develop the competencies and skills sets to improve disaster preparedness response and preparedness efforts
Percent fluid overload for prediction of fluid de-escalation in critically ill patients in Saudi Arabia: a prospective observational study
Background Percent fluid overload greater than 5% is associated with increased mortality. The appropriate time for fluid deresuscitation depends on the patient's radiological and clinical findings. This study aimed to assess the applicability of percent fluid overload calculations for evaluating the need for fluid deresuscitation in critically ill patients. Methods This was a single-center, prospective, observational study of critically ill adult patients requiring intravenous fluid administration. The study's primary outcome was median percent fluid accumulation on the day of fluid deresuscitation or intensive care unit (ICU) discharge, whichever came first. Results A total of 388 patients was screened between August 1, 2021, and April 30, 2022. Of these, 100 with a mean age of 59.8±16.2 years were included for analysis. The mean Acute Physiology and Chronic Health Evaluation (APACHE) II score was 15.4±8.0. Sixty-one patients (61.0%) required fluid deresuscitation during their ICU stay, while 39 (39.0%) did not. Median percent fluid accumulation on the day of deresuscitation or ICU discharge was 4.5% (interquartile range [IQR], 1.7%–9.1%) and 5.2% (IQR, 2.9%–7.7%) in patients requiring deresuscitation and those who did not, respectively. Hospital mortality occurred in 25 (40.9%) of patients with deresuscitation and six (15.3%) patients who did not require it (P=0.007). Conclusions The percent fluid accumulation on the day of fluid deresuscitation or ICU discharge was not statistically different between patients who required fluid deresuscitation and those who did not. A larger sample size is needed to confirm these findings
Combined application of zinc and silicon alleviates terminal drought stress in wheat by triggering morpho-physiological and antioxidants defense mechanisms
Wheat is an important global staple food crop; however, its productivity is severely hampered by changing climate. Erratic rain patterns cause terminal drought stress, which affect reproductive development and crop yield. This study investigates the potential and zinc (Zn) and silicon (Si) to ameliorate terminal drought stress in wheat and associated mechanisms. Two different drought stress levels, i.e., control [80% water holding capacity (WHC) was maintained] and terminal drought stress (40% WHC maintained from BBCH growth stage 49 to 83) combined with five foliar-applied Zn-Si combinations (i.e., control, water spray, 4 mM Zn, 40 mM Si, 4 mM Zn + 40 mM Si applied 7 days after the initiation of drought stress). Results revealed that application of Zn and Si improved chlorophyll and relative water contents under well-watered conditions and terminal drought stress. Foliar application of Si and Zn had significant effect on antioxidant defense mechanism, proline and soluble protein, which showed that application of Si and Zn ameliorated the effects of terminal drought stress mainly by regulating antioxidant defense mechanism, and production of proline and soluble proteins. Combined application of Zn and Si resulted in the highest improvement in growth and antioxidant defense. The application of Zn and Si improved yield and related traits, both under well-watered conditions and terminal drought stress. The highest yield and related traits were recorded for combined application of Zn and Si. For grain and biological yield differences among sole and combined Zn-Si application were statistically non-significant (p>0.05). In conclusion, combined application of Zn-Si ameliorated the adverse effects of terminal drought stress by improving yield through regulating antioxidant mechanism and production of proline and soluble proteins. Results provide valuable insights for further cross talk between Zn-Si regulatory pathways to enhance grain biofortification
