Facilitators and barriers to learning faced by female students with disability in higher education.

This study was aimed to investigate the learning experiences' facilitators and barriers that is encountered by the physically disabled female students during their higher education. Twenty semi-structured interviews were conducted with female students with physical disabilities aged between 19 and 33 years. Interviews were transcribed, confirmed, and analyzed after being recorded. The average age of the sample was 22.15 ± 3.48 years and one-fourth of the participants' disability was due to cerebral palsy and 35% participants used wheelchairs. All the factors promoted inclusive education and equal opportunities for both disabled and nondisabled students. This study reveals that in order to improve the learning experiences of students with disabilities (SwD) and to give them more opportunities for success, it is important to consider all the barriers discussed in this study. It can be concluded that high effort is required to transform the higher educational institutions to be more accommodating for students with disabilities.

The Lucy Thermal Emission Spectrometer (L'TES) Instrument.

The Lucy Thermal Emission Spectrometer (L'TES) will provide remote measurements of the thermophysical properties of the Trojan asteroids studied by the Lucy mission. L'TES is build-to-print hardware copy of the OTES instrument flown on OSIRIS-REx. It is a Fourier Transform spectrometer covering the spectral range 5.71-100 µm (1750-100 cm-1) with spectral sampling intervals of 8.64, 17.3, and 34.6 cm-1 and a 7.3-mrad field of view. The L'TES telescope is a 15.2-cm diameter Cassegrain telescope that feeds a flat-plate Michelson moving mirror mounted on a linear voice-coil motor assembly to a single uncooled deuterated l-alanine doped triglycine sulfate (DLATGS) pyroelectric detector. A significant firmware change from OTES is the ability to acquire interferograms of different length and spectral resolution with acquisition times of 0.5, 1, and 2 seconds. A single ∼0.851 µm laser diode is used in a metrology interferometer to provide precise moving mirror control and IR sampling at 772 Hz. The beamsplitter is a 38-mm diameter, 1-mm thick chemical vapor deposited diamond with an antireflection microstructure to minimize surface reflection. An internal calibration cone blackbody target, together with observations of space, provides radiometric calibration. The radiometric precision in a single spectrum is ≤2.2 × 10-8 W cm-2 sr-1 /cm-1 between 300 and 1350 cm-1. The absolute temperature error is <2 K for scene temperatures >75 K. The overall L'TES envelope size is 37.6 × 29.0 × 30.4 cm, and the mass is 6.47 kg. The power consumption is 12.6 W average. L'TES was developed by Arizona State University with AZ Space Technologies developing the electronics. L'TES was integrated, tested, and radiometrically calibrated on the Arizona State University campus in Tempe, AZ. Initial data from space have verified the instrument's radiometric and spatial performance.

2†Pathways to detection of non-infectious childhood uveitis in the UK: findings from the UNICORN cohort study.

INTRODUCTION: Prompt detection of childhood uveitis is key to minimising negative impact. From an internationally unique inception cohort, we report pathways to disease detection.UNICORNS is a national childhood non-infectious uveitis study with longitudinal collection of a standardised clinical dataset and patient reported outcomes. Descriptive analysis of baseline characteristics are reported.Amongst 150 recruited children (51% female, 31% non-white ethnicity) age at detection ranged from 2-18yrs (median 10). In 69%, uveitis was diagnosed following onset of symptoms: time from first symptoms to uveitis detection ranged from 0-739days (median 7days), with longer time to detection for those presenting initially to their general practitioner. Non symptomatic children were detected through JIA/other disease surveillance (16%), routine optometry review (5%) or child visual health screening (1%). Commonest underlying diagnoses at uveitis detection were JIA (17%), TINU (9%, higher than pre-pandemic reported UK disease frequency) and sarcoid (1%). 60% had no known systemic disease at uveitis detection. At disease detection, in at least one eye: 34% had structural complications (associated with greater time to detection - 17 days versus 4 days for uncomplicated presentation).The larger relative proportions of children with non-JIA uveitis reported here increase the importance of improving awareness of childhood uveitis amongst the wider clinical communities. There is scope for improvement of pathways to detection. Forthcoming analysis on the full cohort (251 recruited to date across 33 hospitals and 4 nations) will provide nationally representative data on management and the determinants of visual and broader developmental/well-being outcomes.

Beta Elemene induces cytotoxic effects in FLT3 ITD-mutated acute myeloid leukemia by modulating apoptosis.

OBJECTIVE: ß-Elemene, a sesquiterpene with a broad anti-cancer spectrum, is particularly effective against drug-resistant and complex tumors. It can also be efficient against FLT3-expressed acute myeloid leukemia. This research aims to determine whether ß-Elemene has cytotoxic effects on FLT3 ITD-mutated AML cells. MATERIALS AND METHODS: Cytotoxicity, cell morphology, mRNA analysis with apoptotic markers, and analysis of 43 distinct protein markers related to cell death, survival, and resistance were all performed to elucidate its mechanism. Additionally, in order to understand how ß-Elemene and FLT3 interact, molecular docking, molecular dynamics simulations, and computational ADME investigations were performed. RESULTS: ß-Elemene exhibited cytotoxic activity against FLT3-mutated MV4-11 and FLT3 wild-type THP-1 cells, with an IC50 of around 25 µg/ml. The molecular studies revealed that ß-Elemene inhibited cell proliferation by inducing p53, and the involvement of p21, p27, HTRA, and HSPs were also demonstrated. The interactive inhibition in proliferation was confirmed via molecular docking and dynamics analyses. ß-Elemene occupied the FLT3 enzymatic pocket with good stability at the FLT3 active site. CONCLUSIONS: We concluded from our observations that ß-Elemene causes cell death in ITD mutant AML cells, together with the effects of stress factors and inhibiting cell division.

In silico elucidation of plausible anti-obesity activity by Withaferin-A compound targeting alpha-amylase.

OBJECTIVE: The study aimed to evaluate the Withaferin-A against the drug target α-amylase, revealing its plausible mode of action and molecular-level interactions essential for this specific target inhibitory potential computational approach. MATERIALS AND METHODS: In this scenario, we used computational methods, including docking, molecular dynamics simulation, and model-building simulations, to elucidate the atomic-level details responsible for the inhibitory potential of Withaferin-A derived from W. somnifera. The studio visualizer software was used for the visualization of ligands, structures of the receptor, bond length, and rendering of the image. Absorption, distribution, metabolism, excretion, and toxicity (ADMET) characteristics of phytochemicals were investigated. Crystal structure of protein receptors and ligands were generated. Semi-flexible docking was done using Autodock software. Docking was performed using the Lamarckian Genetic Algorithm (LGA). Molecular descriptors were evaluated, and the pharmacological properties of the phytochemicals were explored. Molecular dynamic simulations were analyzed at the atomic level. All the simulations were conducted under the same temperature, pressure, and volume circumstances over the simulated time scale. RESULTS: Withaferin-A has shown a strong binding affinity towards α-amylase as demonstrated with -9.79 Kcal/mol with 66.61 estimated nanomolecular IC50 value for plausible anti-obesity activity. Molecular-level relationships and knowledge obtained from this study indicate solid interactions with TYR59, ASP197, and HIS299 residues which are of high importance for future works related to computational screening of target-specific α-amylase inhibitors. The results from the analysis have revealed potential molecular-level interactions useful for further designing/discovering novel α-amylase inhibitors. CONCLUSIONS: The framework of the studied phytochemicals enables the rapid development of subsequent modifications that could result in more lead-like compounds with better inhibitory efficacy and selectivity for α-amylase.

Diagnostic Value of Serum Gamma Glutamyl Transpeptidase (GGT) for Early Diagnosis of Biliary Atresia.

Early differentiation of biliary atresia (BA) from idiopathic neonatal hepatitis (INH) is of important as outcome of Kasai portoenterostomy is directly related to the age of surgery. We need to have a simple and cheap biochemical test in resource poor countries like Bangladesh, to pick up BA early. Serum gamma glutamyl transpeptidase (GGT) has been shown to be a useful marker to differentiate BA from INH. Objective of the study was to find out the diagnostic value of gamma glutamyl transpeptidase (GGT) in differentiating Biliary atresia (BA) from idiopathic neonatal hepatitis (INH). This observational cross section study was carried out at the Department of Pediatric Gastroenterology and Nutrition, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. Study period was from January 2014 to June 2015. Consecutive infants with neonatal cholestasis (defined as conjugated bilirubin >1.0mg/dL when total bilirubin was ≤5.0 or >20.0% to total bilirubin) were included in this study. Clinical details and the results of laboratory tests were recorded in a proforma. BA was diagnosed on the basis of liver biopsy. Different biochemical parameters especially the results of serum GGT level (normal up to 60U/L), were compared between two groups (BA and INH). Receiver Operator Characteristic (ROC) curve for GGT was constructed to find out the best cut off value to discriminate BA from INH by using SPSS (version 20.0). After confirming cholestasis, a total of 165 cases were enrolled for study. Among them 86 cases were diagnosed as INH or BA. Among these 86 cases, 38(44.2%) cases were BA and 48(55.8%) cases were INH. On comparing 38(44.2%) cases of BA with 48(55.8%) cases of INH it was found that low birth weight (13.0% vs. 31.0%, p<0.05), persistently acholic stools (76.0% vs. 44.0%, p=0.002) and mean GGT values (921 vs. 264, p<0.001) were significantly different between them. At a cut off value of 524U/L (8.7 times upper limit of normal) the area under curve (AUC) for GGT was 0.81 with sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy were 81.7%, 72.9%, 70.5%, 83.3% and 76.1% respectively for the diagnosis of Biliary atresia. Serum GGT value of >524 U/L or 8.7 times upper limit of normal value was fairly good in differentiating BA from INH and can be used as a screening investigation in developing countries.

The Effects of Negative Pressure Wound Therapy on Vegf and Angiogenesis in Deep Dermal Burn Injury: An Experimental Study.

Burn injuries are the fourth most common type of trauma worldwide, after traffic injuries, falls and interpersonal violence. Vascular endothelial growth factor (VEGF) is one of the most critical proangiogenic factors. Failure in angiogenesis is often associated with chronic, non-healing wounds. This study aimed to compare the effect of sterile gauze with normal saline (NaCl) 0.9%, intermittent negative pressure wound therapy (NPWT), continuous NPWT, and silver sulfadiazine dressing on increasing VEGF and angiogenesis in deep dermal burn injury. This experimental laboratory study involved six Yorkshire pigs. Twenty burns were made on each pig's flank and dorsum areas, which were divided into four treatment groups: sterile gauze with NaCl 0.9%, intermittent NPWT, continuous NPWT, and silver sulfadiazine dressing. Skin biopsies were done on days 1, 3, 7, 14 and 21 to evaluate VEGF histoscore and mean microvascular density (MVD). We used immunohistochemical staining of VEGF-165 as VEGF's protein marker and hematoxylin-eosin (HE) to count the MVD. There was a significant difference in mean VEGF histoscore on evaluation day 14, in which continuous NPWT had the highest score compared to sterile gauze with NaCl 0.9%, intermittent NPWT, and silver sulfadiazine. The elevated VEGF histoscore could significantly increase the MVD.

Les brûlures représentent la 4ème cause mondiale de traumatisme, après les accidents de la voie publique, les chutes et les violences interhumaines. Le facteur vasculaire de croissance endothéliale (FVCE) est un des principaux facteurs de l'angiogénèse qui, lorsqu'elle dysfonctionne, fait passer les plaies à la chronicité. Cette étude compare les effets de pansements au sérum physiologique (NaCl), des thérapies à pression négative (TPN) continue ou intermittente et de la sulfadiazine argentique (SFDA) sur l'augmentation du FVCE et l'angiogénèse dans les brûlures de 2ème degré profond. Cette étude expérimentale a été conduite sur 6 porcs Yorkshire. Vingt brûlures ont été réalisées sur les flancs et régions dorsales de chacun d'eux, réparties en 4 groupes selon leur traitement : NaCl, TPN intermittente, TPN continue et SFDA. Des biopsies cutanées ont été réalisées à J1, 3, 7, 14 et 21 afin d'évaluer histologiquement le score FVCE (par mesure colorimétrique de FVCE-165) et la densité microvasculaire (par coloration hématoxyline- éosine). À j14, la TPN continue permettait d'obtenir le score FVCE le plus élevé, comparativement aux 3 autres pansements et pourrait augmenter la densité microvasculaire.

Significance of Orlistat in management of dyslipidemia, systolic blood pressure and body mass index.

OBJECTIVE: The current study intends to find out the efficacy of Orlistat in the management of hyperlipidemia, Systolic Blood Pressure (SBP) and Body Mass Index (BMI). MATERIALS AND METHODS: This retrospective study has evaluated the lipid profiles of the patients, who have been using metformin therapy for Type 2 diabetes. The study has obtained data regarding the parameters like triglyceride, Total cholesterol (TC), LDL cholesterol, HDL cholesterol and LDL/HDL ratio, systolic blood pressure and Body Mass Index (BMI). Random distribution of patients was done into placebo and Orlistat groups. The placebo group received only metformin, and patients in the Orlistat group received Orlistat along with metformin. After 24 weeks, the follow-up study was done, and statistical analysis was conducted. RESULTS: The study found that the Orlistat group has significant improvement (p<0.05) more improvement in LDL cholesterol, HDL cholesterol, Total cholesterol, LDL/HDL Ratio and Triglycerides, while BMI and systolic blood pressure did not show a significant difference between placebo and Orlistat group. CONCLUSIONS: This study has concluded that Orlistat can be used for significant improvement in lipid profile. The study also found that Orlistat may not have a significant effect on reducing BMI and blood pressure without adequate lifestyle modification.

Patterns of Thyroid Cancer Mortality and Incidence in Saudi Arabia: A 30-Year Study.

Thyroid cancer is the most prevalent endocrine cancer among the female population in the Kingdom of Saudi Arabia (KSA) and the ninth most common in the male population in Saudi Arabia. Over the past years, an increasing incidence of thyroid cancer has been reported in Saudi Arabia. However, the etiology of thyroid cancer is still not clear. Therefore, this study aimed to estimate thyroid cancer incidence and mortality trends in Saudi Arabia from 1990 to 2019. The current study utilized the Global Burden of Disease and the Institute for Health Metrics and Evaluation databases to extract prevalence data of thyroid cancer in Saudi Arabia from 1990 to 2019. Moreover, the current project utilizes Global Burden of Disease (GBD) web-based tools to visualize these data. In total, 23,846 cases (17,220 females and 6626 males) were diagnosed with thyroid cancer in Saudi Arabia from 1990 to 2019. The incidence is higher in females than in males. Over these 30 years, women's incidence steadily increased by 15-fold versus a 22-fold increase in men. Moreover, there were 2056 deaths in total caused by thyroid cancer in KSA. The mortality rate in women steadily increased by threefold in the same period. However, the increase in mortality was higher in males (sixfold). A high percentage of YLLs was observed in males, with around 24.8% ranging from 30 to 34 and 40 to 45 years. Thyroid cancer incidence rates have increased exponentially between 1990 and 2019. The expansion of the incidence of thyroid cancer in Saudi Arabia could be due to the increased development in detection and diagnosis. The current study provided evidence of the need to increase awareness and diagnosis in the male population.

Role of somatostatin receptor SSRT5-AS1 in predicting biomarkers of primary androgen deprivation therapy on prostate cancer in Indonesian population.

INTRODUCTION: Androgen deprivation therapy (ADT) has been the pivotal strategy for treating advanced prostate cancers. Despite the high efficacy of ADT in prohibiting tumor growth, >50% cases of prostate cancer will develop into an aggressive variant known as castration resistant prostate cancer (CRPC). This study aimed to evaluate the potential role SSRT5-AS1 expression as a biomarker for response to ADT in prostate cancer. MATERIALS AND METHODS: In total, 36 patients diagnosed with prostate cancer at Dr. Sardjito General Hospital, Yogyakarta, Indonesia were enrolled from 2015 and 2019. The expression of SSRT5-AS1 in primary tumors was quantified using quantitative real-time polymerase chain reaction. RESULTS: The mean age of patients enrolled in this study was 69.07 ± 8.7 years, and the mean of prostate-specific antigen in patients was 141.22 ±112.28 ng/ml. Compared with the median, a higher expression of SSTR5-AS1 had more significant prognostic value than the variable shorter time to CRPC (p= 0.043). CONCLUSION: This study demonstrated that high expression of SSRT5-AS1 is a promising biomarker to predict response to ADT in patients with prostate cancer.

Persistent Fever and Cough in a Patient With Good's Syndrome: A Case Report.

Good's syndrome is a rare, acquired immunodeficiency condition characterized by thymoma and hypogammaglobulinemia, which increases the risk of recurrent infections. Immunoglobulin replacement therapy (IgRT) is the key treatment for recurrent infections. We describe the case of a 57-year-old male with a history of an anterior mediastinal mass and a persistent cough lasting for a few years. Based on the clinical history and immunological analysis, he was diagnosed with Good's syndrome. He was being managed conservatively with immunoglobulin until he underwent a thymectomy. Subsequently, he developed his first pneumonia. His conditions gradually worsened despite the initiation of IgRT. He was diagnosed to have hypersensitivity pneumonitis based on strong exposure history, consistent radiological images, and good clinical response to antigen avoidance and steroid therapy. To our knowledge, this is the first case of Good's syndrome with hypersensitivity pneumonitis that was unmasked after immune augmentation by the initiation of IgRT. Moreover, surgical intervention should not be considered unless unavoidable. Additionally, close clinical monitoring and laboratory testing are indicated, and IgRT should be considered when the patient begins to exhibit symptoms to prevent severe infections.

Magnetic Resonance Elastography-derived Stiffness Predicts Renal Function Loss and Is Associated With Microvascular Inflammation in Kidney Transplant Recipients.

Background: Organ stiffening can be caused by inflammation and fibrosis, processes that are common causes of transplant kidney dysfunction. Magnetic resonance elastography (MRE) is a contrast-free, noninvasive imaging modality that measures kidney stiffness. The objective of this study was to assess the ability of MRE to serve as a prognostic factor for renal outcomes. Methods: Patients were recruited from the St Michael's Hospital Kidney Transplant Clinic. Relevant baseline demographic, clinical, and Banff histologic information, along with follow-up estimated glomerular filtration rate (eGFR) data, were recorded. Two-dimensional gradient-echo MRE imaging was performed to obtain kidney "stiffness" maps. Binary logistic regression analyses were performed to examine for relationships between stiffness and microvascular inflammation score. Linear mixed-effects modeling was used to assess the relationship between stiffness and eGFR change over time controlling for other baseline variables. A G2-likelihood ratio Chi-squared test was performed to compare between the baseline models with and without "stiffness." Results: Sixty-eight transplant kidneys were scanned in 66 patients (mean age 56 ± 12 y, 24 females), with 38 allografts undergoing a contemporaneous biopsy. Mean transplant vintage was 7.0 ± 6.8 y. In biopsied allografts, MRE-derived allograft stiffness was associated only with microvascular inflammation (Banff g + ptc score, Spearman ρ = 0.43, P = 0.01), but no other histologic parameters. Stiffness was negatively associated with eGFR change over time (Stiffness × Time interaction ß = -0.80, P < 0.0001), a finding that remained significant even when adjusted for biopsy status and baseline variables (Stiffness × Time interaction ß = -0.46, P = 0.04). Conversely, the clinical models including "stiffness" showed significantly better fit (P = 0.04) compared with the baseline clinical models without "stiffness." Conclusions: MRE-derived renal stiffness provides important prognostic information regarding renal function loss for patients with allograft dysfunction, over and above what is provided by current clinical variables.

Incorporation of Plant Extracted Hydroxyapatite and Chitosan Nanoparticles on the Surface of Orthodontic Micro-Implants: An In-Vitro Antibacterial Study.

In our study, the structural and morphological applications of hydroxyapatite and chitosan nanoparticles and coated micro-implants were assessed for their ability to combat oral pathogenic bacteria. The hydroxyapatite, as well as chitosan nanoparticles, were synthesized from the Salvadora persica plant. The crystal morphology, phase composition, particle size, and surface functional groups of the nano-samples were analyzed via classical examinations and energy dispersive X-ray analysis. The prepared nanoparticles have been examined for antibacterial activity against four common oral bacterial strains. The antimicrobial effect was also assessed by the Live/Dead BacLight technique in combination with confocal scanning laser microscopy. Titanium micro-implants were coated with regular hydroxyapatite (HAP) and chitosan nanoparticles, and the surface was characterized by scanning electron microscopy. The analysis asserted elemental composition of the prepared nanoparticles and their textural features, metal crystallization, and functional bonds. The antibacterial activity of the nanoparticles was evaluated against oral pathogenic microorganisms by the disc diffusion method, minimum bacterial concentration (MBC), and minimum inhibitory concentration (MIC). Chitosan nanoparticles showed (MICs) of 8 µg mL-1 for (Streptococcus salivarius, Streptococcus mutans and Enterococcus faecalis), and 16 µg mL-1 for Streptococcus sanguinis. HAP nanoparticles showed (MICs) of 16 µg/mL for E. faecalis, and S. sanguis, 8 µg/mL for S. salivarius and finally 4 µg/mL for S. mutans. HAP nanoparticles showed enhanced antibacterial activity and more obvious damage in the bacterial cell membrane than that of synthesized chitosan nanoparticles. The prepared nanoparticles could successfully coat titanium microplates to enhance their efficiency.

A survey on workplace violence among pre-hospital care personnel in Malaysia.

INTRODUCTION: Data on violence experienced by pre-hospital care (PHC) staff in developing countries are lacking. This study investigates incidence, effect, coping reaction, and action taken towards violence received by PHC staff in Malaysia, a developing country. MATERIALS AND METHODS: This is a multi-centred crosssectional survey. Questionnaire modified from the Joint Programme on Workplace Violence in the Healthcare Sector was applied. PHC staff include assistant medical officers, emergency medical technicians (EMTs), nurses, attendants, and ambulance drivers. This questionnaire involves workplace violence (WPV) experienced for 12 months since the beginning of this study among pre-hospital staff of three main hospitals in Klang Valley, Malaysia. RESULTS: Seventy-one PHC staff personnel responded to this questionnaire. Overall prevalence of at least one WPV incident over past 12 months was 56.3% (95% CI 44.8% to 65.8%). Fifty-three-point-five percent (95% CI 41.9% to 65.1%) experienced verbal abuse, 9.9% (95% CI 3% to 16.8%) experienced physical abuse, and 14.1% (95% CI 6.0% to 22.2%) experienced racial abuse. None of the participants experienced sexual abuse. Out of 38 staff that experienced verbal abuse, 16 (42%) took no action, 8 (21.1%) pretended it never happened, and only 5 (13.2%) filed an actual complaint. CONCLUSION: Verbal abuse was found to be the most common type of violence. Younger age group (<29 years) was more exposed to verbal (p = 0.014) and racial abuse (p = 0.007). Majority victims either responded by telling abusers to stop or taking no action at all.

Hydrogen sulfide: an emerging component against abiotic stress in plants.

As a result of climate change, abiotic stresses are the most common cause of crop losses worldwide. Abiotic stresses significantly impair plants' physiological, biochemical, molecular and cellular mechanisms, limiting crop productivity under adverse climate conditions. However, plants can implement essential mechanisms against abiotic stressors to maintain their growth and persistence under such stressful environments. In nature, plants have developed several adaptations and defence mechanisms to mitigate abiotic stress. Moreover, recent research has revealed that signalling molecules like hydrogen sulfide (H2 S) play a crucial role in mitigating the adverse effects of environmental stresses in plants by implementing several physiological and biochemical mechanisms. Mainly, H2 S helps to implement antioxidant defence systems, and interacts with other molecules like nitric oxide (NO), reactive oxygen species (ROS), phytohormones, etc. These molecules are well-known as the key players that moderate the adverse effects of abiotic stresses. Currently, little progress has been made in understanding the molecular basis of the protective role of H2 S; however, it is imperative to understand the molecular basis using the state-of-the-art CRISPR-Cas gene-editing tool. Subsequently, genetic engineering could provide a promising approach to unravelling the molecular basis of stress tolerance mediated by exogenous/endogenous H2 S. Here, we review recent advances in understanding the beneficial roles of H2 S in conferring multiple abiotic stress tolerance in plants. Further, we also discuss the interaction and crosstalk between H2 S and other signal molecules; as well as highlighting some genetic engineering-based current and future directions.

Occupational Stressors and Safety Behaviour among Oil and Gas Workers in Kuwait: The Mediating Role of Mental Health and Fatigue.

This paper provides an examination of direct and mediated relationships among occupational stressors (responsibilities towards family and living environment), mental health (anxiety and depression), fatigue (physical and mental fatigue), and safety behaviour (safety compliance and safety participation). In this cross-sectional study, data were collected by means of a questionnaire among oil and gas workers (foreign employees working at a remote oil and gas field site located in Kuwait), during a two-month period (November-December 2018). Regression analyses (bivariate and hierarchical), carried out on 387 responses, were employed to test the links between occupational stressors, mental health, fatigue, and safety behaviour in the hypothesised model. The results provide support for the direct relationship in the model, in that both responsibilities towards family and living environment predicted safety behaviour participation. Further, the results provide partial support for the mediated relationships in the model, as mental health and fatigue were found to mediate the relationship of responsibilities towards family and living environment with safety participation behaviour. It is concluded that occupational stressors have a negative effect on safety behaviour, while mental health and fatigue can operate as risk factors. Given this, it is recommended that organisations need to enhance remote oil and gas workers' safety behaviour by encouraging them to effectively balance their stress, mental health, and level of fatigue. This can be achieved by actions such as promoting spirituality, boosting workers' resilience, providing recreational facilities and encouraging communications.

Acute Severe Hyponatremia following Hysteroscopic Procedure in a Young Patient: A Case Report and Review of the Literature.

BACKGROUND: Hysteroscopic surgery is a minimally invasive procedure used to diagnose and treat intrauterine pathologies. It requires distension of the uterine cavity for the adequate visualization of the operative field. Glycine (1.5%) is one of the most commonly used solutions because it is nonconductive and also has good optical properties. However, acute hyponatremia is a critical complication that can develop after the absorption of a sufficient amount of the irrigation medium. Case Presentation. We report a case of a 43-year-old female patient who developed acute symptomatic hyponatremia (104 mEq/L) and pulmonary edema secondary to hysteroscopic resection of leiomyoma and hastily approached with rapid sodium correction measures. CONCLUSION: Multiple strategies can be taken to reduce the risk of fluid absorption and subsequent hyponatremia. Moreover, attention should be paid to the treatment approach for patients with acute hyponatremia following hysteroscopic procedures; rapid correction of acute hyponatremia for such patients might be safe, although there is no consensus in the literature, and further trials are needed.

Hyperglycemia associated with acute brain injury in neonatal encephalopathy.

OBJECTIVE: To identify how alterations in glucose levels are associated with regional brain injury in neonatal encephalopathy. METHODS: This was a prospective cohort study of 102 newborns with neonatal encephalopathy, with continuous glucose monitoring for 72 h. 97 (95%) completed 72 h of therapeutic hypothermia. Brain imaging around day 5 of life included diffusion tensor imaging and MR spectroscopy. Regions of interest were placed for both DTI and MR spectroscopy, and tractography of the optic radiation and corticospinal tract were evaluated. Linear regression models related each MR metric with minimum and maximum glucose values during each day of life, adjusting for 5-minute Apgar scores and umbilical artery pH. RESULTS: Higher maximum glucose levels on the first day of life were associated with widespread changes in mean diffusivity in the anterior and posterior white matter, splenium of the corpus callosum, lentiform nucleus, pulvinar nucleus of the thalamus, posterior limb of the internal capsule, and optic radiations, thus including regions traditionally associated with hypoxia-ischemia or hypoglycemia. No associations were found between lower minimum glucose levels and DTI changes in any regions tested, or between glucose levels and MR spectroscopy. CONCLUSIONS: In this cohort of neonatal encephalopathy with therapeutic hypothermia, higher maximal glucose on the first day of life was associated with widespread microstructural changes, but lower minimum glucose levels were not associated with changes in any of the regions tested. Long-term follow-up will determine if imaging findings translate to long-term outcomes.

Risk Factors of UTI in Children with Nephrotic Syndrome.

Urinary tract infection (UTI) is a common complication in nephrotic children and leads to most morbidity and mortality in developing countries like Bangladesh. This case control study was conducted in the Department of Pediatrics and Pediatric Nephrology ward of Dhaka Medical College Hospital, Dhaka from July 2016 to June 2018 to identify the risk factors of UTI in children with nephrotic syndrome. Total 90 patient of nephrotic children aged 2-12 years, who were fulfilling the inclusion and exclusion criteria were selected as Group I (case) and Group II (control) according to urine culture report. Group I was UTI positive and Group II was UTI negative. The mean age of Group I was 5.26±3.18 years and Group II was 6.03±2.85 years. There was male predominance in both groups. No significant difference has been found regarding age and sex (p>0.05). No significant difference was also observed regarding economic status and educational level of mother among both groups (p>0.05). Fever, dysuria, abdominal pain, anasarca, vomiting and pallor were found as common presentations in Group I. Children with dysuria and abdominal pain were significantly higher in Group I than Group II (p value <0.001). UTI was found more in relapsed cases than initial attack. E. coli was the most common etiologic agent (37.8%). Mean Hb (gm/dl), serum total protein, serum albumin and serum IgG level were found significantly lower and spot urine protein creatinine ratio was significantly higher in Group I, which implies that those biochemical factors were associated with development of UTI in nephrotic children. Younger age group (<6 years), Constipation and uncircumcised male were found as risk factors and has association with UTI in nephrotic children.

Factors associated with the use of fashion braces of the Saudi Arabian Youth: application of the Health Belief Model.

BACKGROUND: In spite of the fact that fashion braces (FBs) have been in the spotlight in recent years among both orthodontists and the general public in several countries, there is still limited evidence regarding FBs. The aim was to identify health-related behaviors in using FBs by considering the Health Belief Model (HBM). METHODS: A cross-sectional study with a random sampling technique was conducted in Jazan, Saudi Arabia. The data was obtained from different middle and high schools students, and first-year students at Jazan University. The questionnaire collected data on demographic characteristics and 27 items to examine the constructs of the HBM. Chi Square test was carried out to establish the factors associated with using, the intention to use, and previous knowledge on the use of fashion braces. Logistic regression analysis was utilized to determine the factors associated with the use of fashion braces. RESULTS: 406 study participants completed the questionnaire with a response rate of 88.3%. Majority of respondents were males (52.2%) and > 19 years old (44.3%). Only 9.9% students had used the FBs. However, 25.7% of students had the intention to use them. The perceived susceptibility, perceived benefits and cues to action constructs scores were fair with the mean values of 15.38 (SD = 9.4), 28.17 (SD = 10.8) and 6.65 (SD = 2.50), respectively. However, the perceived barrier score was high with the mean values of 22.14 (SD = 7.50), and lower score of self-efficacy with mean of 8.73 (SD = 3.30). Gender, age, monthly income (family), and education level were significantly (p < 0.05) associated with the use of fashion braces among the study's participants. Based on the results of logistic regression analysis family income, perceived susceptibility, and risk severity constructs predict the use of fashion braces in the study's sample. CONCLUSIONS: The current study suggests that the family income, perceived susceptibility, and risk severity of students significantly influence the use of fashion braces. Hence, it is recommended that researchers should investigate effective educational strategies and programs for improving young people's knowledge about fashion braces and focus more on low family income students so that their using of fashion brace will be decreased.
