Parental beliefs, attitudes, and practices on nutrition and children feeding: implications to preventive measures on children's obesity in Saudi Arabia.

OBJECTIVE: Parents have a profound influence on their children's dietary habits. Parents' perspectives, attitudes, and behaviors regarding feeding their children a nutritious diet can have a significant impact on their children's health. The objective of this study was to examine the attitudes, beliefs, and feeding practices of parents in relation to nutrition for their children and to determine how these factors influence strategies for preventing obesity. SUBJECTS AND METHODS: A total of 446 Saudi mothers with children aged 2-12 years were recruited for this study. The Child Feeding Questionnaire (CFQ) was administered to mothers via an instant messaging application. RESULTS: Mothers' age showed a significant difference in perceived responsibility (p < 0.004), perceived parental weight (p = 0.000), perceived child's weight (p = 0.000), and concern about the child's weight (p = 0.000). Mothers with postgraduate degrees exhibited a significant difference in perceived child weight (p < 0.003); occupational status showed a significant difference in perceived parental weight (p < 0.004), perceived child weight (p < 0.001), and residence, particularly in Riyadh, which showed a significant difference in perceived parental weight (p < 0.026). There were also significant differences in body mass index (BMI) (p = 0.000) and perceived parental weight in relation to the mother's age. Mothers' age was significantly related to food restrictions (p = 0.000), pressure to eat (p = 0.000), and monitoring (p < 0.009). Mothers with only one child displayed significance in relation to pressure to eat (p < 0.019), while government-employee mothers showed a significant relationship with food restrictions (p < 0.005). There was a noteworthy association between the age of the mothers and perceived responsibility (p < 0.001), occupation (p < 0.22), residence (p = 0.000), and the mother's BMI (p = 0.000) with perceived parental weight. Finally, occupation (p < 0.006) was found to significantly influence food restriction, while the mother's age was significantly related to the pressure to eat (p < 0.002). CONCLUSIONS: Parental attitudes, practices, and beliefs regarding child feeding were strongly associated with maternal age, occupation, and BMI. Targeted interventions should be developed to assist mothers exhibiting these characteristics in establishing healthier and more effective feeding routines for their children. For example, interventions could be designed to educate parents on the latest findings regarding child-feeding habits and help them develop a greater sense of responsibility for their children's nutrition.

Para-Cardiac Inflammatory Mass Compressing the Heart: A possible association with COVID-19.

Infection with the SARS-CoV-2 virus causes coronavirus disease 2019 (COVID-19). COVID-19 usually affects the lungs but may also involve other organs such as the heart. We report a case of a para-cardiac mass in a previously healthy 45-year-old male who developed persistent dyspnea following SARS-CoV-2 infection. The patient underwent cardiac surgery since the mass was attached to the pericardium and was causing constrictive pericarditis. The pathology report indicated an inflammatory pattern for the mass. Based on the authors' knowledge there has been no previous report of developing a para-cardiac inflammatory mass after SARS-CoV-2 infection. This report aimed to increase awareness regarding the possibility of developing a para-cardiac inflammatory mass following COVID-19.

Concentrations of TENORMs in the petroleum industry and their environmental and health effects.

Crude oil and its products and wastes are among the significant sources of naturally occurring radioactive materials (NORMs). These materials may be enhanced to high levels due to technological and human activities, which are called technologically enhanced naturally occurring radioactive materials (TENORMs). Thus, the average radioactivity of these radionuclides sometimes exceeds the exemption level of 10 000 Bq kg-1, which is recommended by the IAEA's safety standards. TENORMs in the oil and gas industry may generate greater radioactivity levels, which eventually represents potential environmental and health risks. This will require continuous attention by monitoring and surveillance during routine processes in the petroleum industry. In this paper, a comprehensive review of the published literature is conducted to evaluate the TENORM concentrations in the oil and gas industry. Moreover, their environmental and health hazards in different regions of the world are discussed.

Relationship between organizational climate and empowerment of nurses in Menoufiya hospitals, Egypt.

One factor influencing the outcome of care may be the nursing staffs experience of organizational work climate. We compared organizational climate and nurse's empowerment in specialty units at 2 hospitals in Egypt. Data were collected from 164 diploma school staff nurses using 2 tools: the situational outlook questionnaire to assess organizational climate and the psychological empowerment in the workplace questionnaire. There was no statistically significant difference in the level of organizational climate between the 2 hospitals, which the majority of nurses classified as moderate. Most nurses reported a moderate level of empowerment in both hospitals and there was a statistically significant positive correlation between organizational climate and nurse's empowerment.

Nicotine and stress: effect on sex hormones and lipid profile in female rats.

This work aimed to study the changes in sex hormones and lipid profile in adult female albino rats subjected to treatment with nicotine (N), immobilization stress (S), or their combinations (N+S). These treatments were applied either for one day (T1) or daily for 10 days (T10), after which rats in the estrus stage were used for the determination of plasma corticosterone (CS), serum sex hormones as progesterone (P), estrogen (E), FSH, LH and serum lipid profile including total cholesterol (TC), HDL-C, LDL-C, triacylglycerol (TG) and non esterified fatty acids (NEFA). It was clear that either N or S raised plasma CS and serum P levels in both the treatment regimens and that N+S induced a higher level of these hormones compared to each treatment alone. Serum E level was only elevated during T10 regimen only. An increase in serum LH level was only observed after a single exposure to either N or S, however their combination abolished the stimulatory effect induced by each treatment alone. Serum FSH was not altered by exposure to either N or S alone in both regimens, but in the T10 regimen their combination significantly lowered FSH level. Regarding the effect on serum lipid profile, serum TC was increased in all T10 regimen groups. LDL-C was increased by N+S treatment in both regimens, however no change in HDL-C level was observed in all groups. Serum NEFA was increased in all the treated groups during T10 regimen, while in the T1 regimen NEFA level was only elevated by the combination N+S. Serum TG was insignificantly altered in all the treated groups. The observed changes in the lipid pattern were attributed to the alterations occurred in CS and female sex hormones that caused by N, S or their combinations.

Comparative study of two filling techniques using glass-ionomer (Ketac-endo) root canal cement on fracture resistance of endodontically treated roots (in vitro).

Forty freshly single rooted teeth were selected for this study. The coronal part of teeth were decapitated and the root canals were prepared by modified step-back technique with K-flex files to size 35# at the apex, five ml of 5.25% NaOCl was used as irrigating solution. According to the dentin thickness at the mesio-distal direction of the prepared roots, roots were divided into two groups: Group (I), dentin and cementum thickness from 1.5-2 mm, and Group (II), dentin and cementum thickness 1 mm. According to the filling technique used the teeth were subdivided into four subgroups each of five teeth; Subgroup (A) single gutta-percha cone and Ketac-endo root canal sealer, Subgroup (B) lateral condensation technique with gutta-percha and Ketac-endo sealer, Subgroup (C) laterally condensed gutta-percha with Roth 801 cement and Subgroup (D) teeth left unfilled as negative controls. The prepared roots were placed into acrylic resin so that 10 mm of the root was exposed. A slowly increasing force was applied vertically using a blunt punch with 1 mm tip thickness attached to Instron testing machine. The results showed that group (I) with 1.5-2mm dentin thickness required greater force to fracture in all experimental groups, than that of group (II) with 1 mm dentin thickness. So the amount of remaining dentin thickness significantly affected the resistance to fracture of the prepared roots.

An investigation on the shear bond strength of three dentine adhesives.

The aim of this investigation was to compare the shear bond strengths of three dentine adhesives tested using an Instron Universal Testing machine at a crosshead speed of 0.5 mm/min. Sixty human molar teeth were used and divided into 3 equal groups where the occlusal surfaces were ground and adhesives were applied overlaid by composite material. Samples were fixed to the Universal Testing machine. Results were recorded in kg/cm2 and converted into MPa units then tabulated and statistically analyzed. Duncan's multiple range statistic test at p < 0.05 showed no statistically significant difference between the shear bond strength values of Scotchbond 2 and Amalgambond; whereas the shear bond strength values of Scotchbond 2 and Amalgambond were significantly higher than those of Gluma. Scanning electron microscopic examinations at X10 and X2500 magnifications showed a dominant adhesive pattern of failure in the samples treated with Gluma, and a mixture of cohesive and adhesive-cohesive patterns of failures in the samples treated with Scotchbond 2 and cohesive patterns of failures in the samples treated with Scotchbond 2 and Amalgambond.

Dentine roughness after different surface treatments.

Surface roughness is one of the most influential criteria affecting the durability and strength of the adhesive restorative materials to the dentine. This study was carried out to investigate the roughness of the dentine surface after some of the modalities proposed for its treatment prior to application of the DBA. Dentine surface roughness of the sixty teeth divided into 12 groups were tested where the dentine surfaces were denuded and were brought to a similar 600 grit surface roughness then different treatments were carried out using H2O2, CO2 gas laser at 30 and 48 J/cm2 energy densities, EDTA and polyacrylic acid treatments. The dentine surface roughness was determined using a profilometer and the results were digitized and plotted using an AUTO-CAD software and Rolland plotter to compare the effects of the different treatments on the dentine surface roughness of the tested samples. Results revealed that the laser treatment left smooth dentine surface and added further evidences to the simplicity and reliability of the conventional use of EDTA and the polyacrylic acid according to the type of adhesive to be used.
