Health Promotion Behaviors among Elderly in Nursing Home at Baghdad City

Abstract Objective: The aim of this study is to evaluate the elderly health promotion behavior through use five domains of physical activities, nutrition patterns, drugs use, psychological well being, seeking of health care. And also to determine the relationship between health promotion behaviors and demographic characteristics(age, gender, and level of education.Methodology: non- experimental (descriptive study) conducted in nursing home at Baghdad city among elderlys' on A non-probability (purposive sample) of (N=80) person were matched with them from general population. The data were collected through the use of semi-structured interview by questionnaire, which consists of two parts (1) divide, section A. cover letter and B. Sociodemographic data which consists of 3-items, (2) health promotion behaviors questionnaire consists of 60-items distributed to four dimensions include, domains, physical activities, nutrition patterns , drugs use, psychological well being, and seeking of health care.Results: The findings of the  present  study  indicate that most the elderlys' unable on practicing physical activity in nursing home residents The drug use domain is perfect for health promotion behaviors domains among elderlys' in nursing home residents, and demographic data no impact upon heath promotion behaviors. Recommendations: The study recommends that Implementation of health education programs by the Ministry of Labor and Social Affairs to improve the elderlys' health promotion behaviors. The elderly of nursing home residents can be considered the target for programs to applying and reinforcing health      promotion issues.   Keywords : health promotion behaviors, elderlys', nursing hom

EXPERIMENTAL STUDY OF THE EFFECT OF WELDING ELECTRODE TYPES ON TENSILE PROPERTIES OF LOW CARBON STEEL AISI1010

This paper discussed the effect of welding variables on the heat-affected zone (HAZ) by using a tensile test of welded 10 mm thick low carbon steel AISI1010 commercial plate, which is welded using the Shielded Metal Arc Welding (SMAW) method. Different welding electrodes E6013 and E7018 were considered as welding parameters investigated. After that, the welded specimens were cut and machined to standard configurations for tensile test. The results showed that selecting different welding electrodes had a remarkable effect on the mechanical properties such as the ultimate tensile strength, elongation percentage, and yield strength of the welded specimens. The increment in the electrical current for each electrode in the welding processes led to decrease in yield strength and tensile strength. The initial decrease in tensile strength and yield strengths were observed. This behavior was attributed to the fact that different welding electrodes and increased the required electrical current to melting for the welding electrode, increased the electrical current led to increased heat input on heat affected zone (HAZ), then the observed change mechanical properties [which could create area for defect. The welding processes and tensile test at a room temperature was performed

Smooth-Muscle BMAL1 Participates in Blood Pressure Circadian Rhythm Regulation

As the central pacemaker, the suprachiasmatic nucleus (SCN) has long been considered the primary regulator of blood pressure circadian rhythm; however, this dogma has been challenged by the discovery that each of the clock genes present in the SCN is also expressed and functions in peripheral tissues. The involvement and contribution of these peripheral clock genes in the circadian rhythm of blood pressure remains uncertain. Here, we demonstrate that selective deletion of the circadian clock transcriptional activator aryl hydrocarbon receptor nuclear translocator-like (Bmal1) from smooth muscle, but not from cardiomyocytes, compromised blood pressure circadian rhythm and decreased blood pressure without affecting SCN-controlled locomotor activity in murine models. In mesenteric arteries, BMAL1 bound to the promoter of and activated the transcription of Rho-kinase 2 (Rock2), and Bmal1 deletion abolished the time-of-day variations in response to agonist-induced vasoconstriction, myosin phosphorylation, and ROCK2 activation. Together, these data indicate that peripheral inputs contribute to the daily control of vasoconstriction and blood pressure and suggest that clock gene expression outside of the SCN should be further evaluated to elucidate pathogenic mechanisms of diseases involving blood pressure circadian rhythm disruption

A systematic review and meta-analysis of the association between exposure to potentially toxic elements and gestational diabetes mellitus

Abstract Potentially toxic elements (PTEs), including heavy metal exposures, have been associated with numerous negative pregnancy and birth outcomes. However, the association between PTE exposure and gestational diabetes mellitus (GDM) has not yet undergone a comprehensive systematic review. Consequently, this study undertook the first-ever systematic review and meta-analysis of observational studies concerning this association. All relevant articles published in English were searched in Scopus, PubMed, and Web of Science until November 6, 2023, adhering to the MOOSE guidelines. The quality of retrieved studies was evaluated based on the Gascon et al. method. The meta-analysis of association estimates was performed using random effects meta-analysis. Egger’s regression was employed to evaluate publication bias. In total, 16 articles (n = 116,728 participants) were included in our review, with 11 eligible for meta-analysis. Quality assessment categorized five studies (31%) as excellent, nine studies (56%) as good, and two studies (13%) as fair. Maternal high levels of Hg during pregnancy were associated with an increased risk of GDM (for each one-quartile increase in Hg: 1.20, 95% CI 1.08, 1.31), while serum Cd levels during the second trimester were associated with a lower risk of GDM (for each one-quartile increase in Cd: 0.76, 95% CI 0.65, 0.87). Furthermore, exposure to Pb was not associated with higher risk of GDM. In summary, our comprehensive review and meta-analysis underscore the possible negative influence of Hg exposure on GDM
