Mixed convective flow of a magnetohydrodynamic Casson fluid through a permeable stretching sheet with first-order chemical reaction.

This research article presents the magnetohydrodynamic Casson fluid flow through an extending surface embedded in a porous medium. Furthermore, the Casson fluid flow is investigated under the effects of thermal radiation, Joule heating, viscous dissipation, and chemical reaction. The analytical solution of the modeled problem is utilized with the help of homotopy analysis method (HAM). The convergence region of the applied technique is portrayed graphically. The impacts of the embedded factors on the flow profiles are exhibited with the help of figures. Furthermore, numerical values of the surface drag force, heat, and mass transfer rates are highlighted via table. The results show that the augmented Darcy number, Casson and magnetic parameters have declined the velocity profile of the Casson fluid flow. Growth in Brownian motion augments the chaotic motion amongst the particles due to which the kinetic energy of the particles transforms to heat energy which consequently augmented the thermal profile, while reduced the concentration profile. The mass and energy profiles are positively effects with the increment of thermophoresis term. And the growing values of chemical reaction and Lewis number cause a reduction in the diffusivity of mass of fluid due to which less transfer of mass takes place that weakens the concentration layer thickness and declines the concentration profiles.

Low back pain and its correlations with poor sleep quality among health care providers.

OBJECTIVE: This study investigates the relationship between low back pain (LBP) and sleep quality among health care workers in KSA. METHODS: In this cross-sectional study, an anonymous questionnaire consisting of three sections was administered to health care providers in KSA. The first part included the biographic data of participants, while the second comprised the Oswestry Disability Index (ODI) and the extended version of the Nordic Musculoskeletal Questionnaire (NMQ-E) for LBP. The third part contained the Pittsburgh Sleep Quality Index (PSQI). RESULTS: A total of 442 healthcare providers completed the questionnaire. Nearly two-thirds of the respondents were male (62.7%). Most were living in either the central region (23.3%) or the northern region (23.3%). There was a statistically significant correlation between the global PSQI and ODI score (r = 0.235; p < 0.001). The correlation between ODI score and PSQI components including subjective sleep quality (r = 0.229; p = 0.007), habitual sleep efficiency (r = 0.229; p < 0.01), and the daytime dysfunction was also statistically significant. CONCLUSION: Health care providers in KSA with high rating for LBP disability demonstrated poorer overall sleep quality and vice versa. However, further research is essential to investigate whether this relationship is causal.

Osteogenesis Imperfecta and Child Abuse From a Forensic Point of View.

Osteogenesis imperfecta (OI) also called brittle bone disease is a rare genetic disorder that results from a defect in type 1 collagen, which is a main structural protein involved in the structure of bones, tendons, ligaments, the dentin layer of teeth, and the sclera of the eye. The defect in this gene is known to be a predisposing factor to fractures. The deficiency in type 1 collagen can be either qualitative or quantitative. Due to this deficiency, the bones become so fragile and can break easily with minimal trauma, which can be coined as "imperfect bone formation." It also leads to bruises due to the extravasation of blood in the connective tissue of the skin. Sometimes, fractures may result from the routine handling of parents. It can be misleading since fractures are considered to be the second most common sign of child abuse according to the literature. One of the main duties in forensic medicine is examining live victims, which plays a crucial role in confirming a clinical diagnosis. In this paper, a review of the literature was conducted and a summary of reported cases of osteogenesis imperfecta, which were initially diagnosed as child abuse, is presented. The aim of this study was to review the literature for the prevalence of misdiagnosed cases of osteogenesis imperfecta as child abuse, analyzing various types of presentations in osteogenesis imperfecta that might lead a physician to a wrong diagnosis of child abuse and to clarify common findings and fracture sites seen among patients with osteogenesis imperfecta. The literature review was conducted for both conditions, osteogenesis imperfecta and child abuse, and an evaluation and analysis of case reports and case series regarding osteogenesis imperfecta cases misdiagnosed as child abuse utilizing the PubMed search engine. Unexplained fractures in children validate the consideration of osteogenesis imperfecta and child physical abuse. A thorough and careful evaluation is recommended as soon as possible because a delay can result in psychological consequences for both the child and the family.

Association of prenatal maternal perceived stress with a sexually dimorphic measure of cognition in 4.5-month-old infants.

Maternal prenatal stress can adversely impact subsequent child neurodevelopment, but little is known about its effect on cognitive development in infancy. This analysis of 107 infants from a prospective birth cohort assessed whether prenatal stress disrupts sexually dimorphic performance typically observed on a physical reasoning task. Maternal stress was assessed at 8-14 and 33-37 gestational weeks using the Perceived Stress Scale. Stress was defined as: low (scores below the median at both times), medium (scores above the median at one of the two times), and high (scores above the median at both times). At 4.5 months infants saw videos of two events: one impossible and the other possible. In the impossible event a box was placed against a wall without support underneath. In the possible event the box was placed against the wall, supported by the floor. Looking time at each event was recorded via infrared eye-tracking. Previous literature has shown that, at 4.5 months of age, girls typically look significantly longer at the impossible than at the possible event, suggesting that they expect the unsupported box to fall and are surprised when it does not. Boys tend to look equally at the two events suggesting that they do not share this expectation. This sex difference was replicated in the current study. General linear models stratified by sex and adjusted for household income, maternal education, mother's age at birth, infant's age at exam, and order of event presentation revealed that girls whose mothers reported high perceived stress during pregnancy had shorter looking time differences between the impossible and possible events than girls whose mothers reported low perceived stress (ß = -7.1; 95% CI: -12.0, -2.2 s; p = 0.006). Similar to boys, girls in the highest stress category spent about the same amount of time looking at each event. For boys, there were no significant looking time differences by maternal stress level. This finding suggests prenatal stress is associated with a delay in the development of physical reasoning in girls.

Evaluation of medication counseling practice at community pharmacies in Qassim region, Saudi Arabia.

INTRODUCTION: Pharmacists have a unique opportunity to promote good health through assuring the quality use of medicines. One of the most important tools to achieve this is medication counseling. Counseling plays an important role in enhancing medication adherence and optimizing medication therapy. Therefore, for improving the quality of services delivered by community pharmacists, it is essential to assess the current situation of counseling services delivered to patients. AIMS AND OBJECTIVES: To date, there is a paucity of data regarding the quality of counseling services delivered to patients in community pharmacies in Saudi Arabia. This study aims to fill this gap through evaluating the counseling skills and counseling content delivered by pharmacists in a sample of community pharmacies in Qassim region, Saudi Arabia. METHODS: The study was conducted at eleven community pharmacies in Qassim region. A convenient sample of community pharmacies was chosen based on their willingness to participate. To gather information, a form was prepared based on the core and complementary drug use indicators for evaluation of drug use in healthcare settings developed by the WHO. The study was conducted through observing the counseling services performed by the community pharmacists who participated in the study. RESULTS: Two hundred and thirty-five forms were completed in eleven community pharmacies. A total of 44.4% of the counseling skills was found to be performed adequately, while only 20.1% of the counseling contents were performed adequately. CONCLUSIONS: The overall standard of medication counseling services provided to patients to improve usage of their medications, and consequently, their well-being was poor.

Development, impact and outcomes of the Hull Bacteraemia Service.

BACKGROUND: Bacteraemia is a significant cause of mortality and healthcare expenditure. Evidence suggests that consultation by an infection specialist may improve outcomes. AIM: To review the characteristics and outcomes of patients seen by a newly implemented bacteraemia service. METHODS: Retrospective review of data collected at time of consultation. Economic analyses and benchmarking of outcomes were also performed. RESULTS: One hundred and fifty-one patients were seen by the service over an 18-month period. Staphylococcus aureus was the most common isolate and central venous lines the most common source. Antibiotics were changed and additional investigations suggested in 62% and 61% of patients, respectively. The 30-day mortality was 19%. Implementation and delivery of the service over the 18-month study period cost pound 22,663 (pound 15,109 per year). The cost per change in antibiotic prescription was pound 244. The cost per 'near-miss' detected was pound 1193. Overall mortality was no higher and possibly lower than in published studies. CONCLUSION: We believe that this model of care may be suitable for the management of patients with bacteraemia. A study assessing the cost-effectiveness of this approach is required.
