Unravelling the complexities of nutritional behaviours in hospital nurses: a commentary on enablers and barriers to healthy eating

Commentary on: Marko S, Wylie S, Utter J. Enablers and barriers to healthy eating among hospital nurses: a systematic review. Int J Nurs Stud. 2023 Feb;138:104412. doi: 10.1016/j.ijnurstu.2022.104412. Epub 2022 Dec 5

Implications for practice and research

Multi-faceted interventions are key in addressing various influences on nurses’ healthy eating beyond individual choices.

Rigorous studies are needed to assess multi-level socio-ecological interventions’ effectiveness on nurses’ eating habits.

Context

Nurses, despite playing a significant role in healthcare, have been found to possess poor dietary habits and face elevated rates of chronic illnesses. A recent systematic review by Marko and colleagues explored factors influencing healthy eating among nurses in hospital settings. Barriers included high accessibility of unhealthy foods, high costs and lack of storage/preparation facilities. Enablers included proximity to healthy options, roster planning and structured workplace programmes. Supportive networks were an interpersonal enabler, while work culture and...

SRY gene isolation from teeth for forensic gender identification—An observational study

by Prathibha Prasad, Mohamed Jaber, Dinesh Y., Prathibha Ramani, Abdulrahman Arafat, Abdalla Khairy

Personal identification in forensics is possible with gender determination using DNA (deoxyribonucleic acid) analysis. DNA isolation from teeth samples subjected to extreme temperatures has been shown to predict the gender of the deceased. However, the literature lacks studies on DNA extracted from tooth samples exposed to freezing temperatures. This study aimed to isolate the SRY gene from the extirpated pulp of teeth that were subjected to varying temperatures for gender identification. Thirty teeth with vital pulps, divided into 3 groups were included in the study. Each group consisted of 5 male and 5 female tooth samples. The groups were exposed to diverse environmental factors for three weeks. Group 1: room temperature (R group); Group 2: high temperature (H group) and Group 3: freezing temperature (F group). Later, DNA was isolated from the pulp tissue, and the SRY gene was amplified using PCR (Polymerase Chain Reaction). The Sensitivity and Specificity of the results were analyzed. SRY gene detected in the study samples identified accurate gender with a 46.70% Sensitivity and 93.30% Specificity. Significant difference was found in the correlation between gene expression and gender among the three groups (p = 1.000). The study validates that dental pulp tissue can be a reliable source for DNA extraction. And SRY gene amplification from teeth exposed to diverse environmental conditions. Further investigations are required to validate its application in forensics.
