The happiness and mental health of individuals are crucial for national developments. In Saudi Arabia, wellbeing occupies a central position in Vision 2030, along with women’s empowerment. Rapidly changing rights and responsibilities might result in more sources of stress. The aim of this study was to explore happiness and mental health among Saudi women during their contributions to a fast-growing nation in all fields. We assessed happiness and mental health (somatic symptoms, depression, anxiety, insomnia, and social dysfunction) in 308 Saudi women aged 15–50 years using a self-administered online survey comprising the short Oxford Happiness Questionnaire (OHQ-8) and the General Health Questionnaire (GHQ-28). The participants demonstrated general satisfaction yet showed rising psychological distress. Married women reported better mental health compared to single women, particularly with regards to anxiety, insomnia, and depression. Depression was highest among younger women. Employed women demonstrated lower social functioning compared to unemployed women. Women with a higher educational level showed lower social functioning. Happiness scores were significantly and inversely related with overall mental health scores as well as mental health subscales (somatic, anxiety, and depression), except for social dysfunction, which showed a positive correlation to happiness scores. This study contributes to the body of literature on women’s mental health and happiness by providing recommendations for improving both as well as directions for future research.

Background: Nursing students constitute the future nursing workforce; their knowledge can readily influence potential donors’ decisions on organ donation. This study aimed to assess nursing students’ knowledge of organ donation, determine its impact on their attitude, and identify relevant factors. Methods: A cross-sectional comparative study assessed the level of knowledge and attitude toward organ donation among nursing students using the following two questionnaires: (1) knowledge about organ donation and (2) attitudes toward posthumous organ donation. Non-probability convenience sampling was employed to collect data. Results: A total of 278 nursing students demonstrated a low level of knowledge on organ donation, with a score of 6.43 out of 15. This influenced their attitude toward organ donation (χ² (3) = 33.91, p < 0.001). Nursing students who were willing to donate their organs showed higher knowledge (7.33 ± 3.23) compared to those who were not willing to donate their organs (5.21 ± 3.09), p < 0.001. Registered donors had higher knowledge (8.52 ± 2.99) than non-donors (5.80 ± 3.17), p < 0.001. Conclusions: Even though nursing students typically favor organ donation, findings have revealed a low knowledge score. Therefore, it is necessary to improve knowledge of organ donation through nursing curricula and research, which could potentially increase the number of donors among future nursing students and, by extension, the broader population.

The COVID-19 pandemic has had a tremendous effect on health systems, leading to a spike in stress, anxiety, and depression conditions among healthcare workers worldwide. Considering the mental health status of nurses, a pillar of the health system, is crucial for assuring the quality of the healthcare provided during and after pandemics. This study aimed to explore the experiences of female nurses who witnessed their patients dying of COVID-19. Seven female COVID-19 nurses were interviewed in person. Thematic analysis of the respondents’ verbatim answers was implemented. Six main themes were identified. Theme 1 illustrates nurses’ experience of emotional and psychological trauma as they witnessed their patients with COVID-19 die under their care. Theme 2 reveals aftershock reactions, including somatization, isolation, and emotional disengagement. Theme 3 highlights the hindrances and difficult situations related to the in-hospital care of COVID-19 patients. Theme 4 demonstrates victorious feelings and celebration of the patient’s survival. Theme 5 emphasizes the nurse’s ability to be calm and recognize the takeaways or lessons they have learned from this phase for their careers and lives. Theme 6 sheds light on nurses’ emerging abilities and competencies. This study will hopefully provide a basis for a debriefing program that might be beneficial to the nurses and the health system. This might affect nurses’ ability to work closely with patients, cope emotionally with challenges, and fulfil their professional tasks.

Heat stroke, a hazardous hyperthermia-related illness, is characterized by CNS injury, particularly long-lasting brain damage. A root cause for hyperthermic neurological damage is heat-induced proteotoxic stress through protein aggregation, a known causative agent of neurological disorders. Stress magnitude and enduring persistence are highly correlated with hyperthermia-associated neurological damage. We used an untargeted proteomic approach using liquid chromatography–tandem mass spectrometry (LC-MS/MS) to identify and characterize time-series proteome-wide changes in dose-responsive proteotoxic stress models in medulloblastoma [Daoy], neuroblastoma [SH-SY5Y], and differentiated SH-SY5Y neuron-like cells [SH(D)]. An integrated analysis of condition–time datasets identified global proteome-wide differentially expressed proteins (DEPs) as part of the heat-induced proteotoxic stress response. The condition-specific analysis detected higher DEPs and upregulated proteins in extreme heat stress with a relatively conservative and tight regulation in differentiated SH-SY5Y neuron-like cells. Functional network analysis using ingenuity pathway analysis (IPA) identified common intercellular pathways associated with the biological processes of protein, RNA, and amino acid metabolism and cellular response to stress and membrane trafficking. The condition-wise temporal pathway analysis in the differentiated neuron-like cells detects a significant pathway, functional, and disease association of DEPs with processes like protein folding and protein synthesis, Nervous System Development and Function, and Neurological Disease. An elaborate dose-dependent stress-specific and neuroprotective cellular signaling cascade is also significantly activated. Thus, our study provides a comprehensive map of the heat-induced proteotoxic stress response associating proteome-wide changes with altered biological processes. This helps to expand our understanding of the molecular basis of the heat-induced proteotoxic stress response with potential translational connotations.

Type 2 Diabetes Mellitus (T2DM) is a widespread metabolic disorder that can affect brain health, primarily through the damaging effects of prolonged hyperglycemia. This condition increases oxidative stress (OS), neuroinflammation, and neuroapoptosis, ultimately impairing cognitive function. Acrylamide (ACY), a neurotoxicant formed during high-temperature food processing and present in cigarette smoke, may further aggravate these neurological disturbances. The present experiment examined the exacerbating effects of T2DM and ACY exposure on cognitive function, neurodegeneration, OS, neuroinflammation, and neuroapoptosis in diabetic rats. T2DM was induced via intraperitoneal injections of nicotinamide and streptozotocin, followed by daily oral doses of ACY for a month. Behavioral assessments (EPM, NOR, and Y-maze) evaluated cognitive performance. Brain tissues were analyzed for biochemical markers of neurodegeneration (GSK-3β, AChE, BACE1), OS (MDA, GSH, Catalase), neuroinflammation (NF-κB, TNF-α, PGE2, COX-2), and neuroapoptosis (Bcl-2, Bax, Caspase-3). Immunohistochemistry of Bcl-2, Bcl-6, CD138, and NF assessed structural brain changes. Results indicated that T2DM and ACY exposure significantly increased the incidence of neurological disturbances. Notably, through increased COX-2, PGE2, MDA, Bax, Bcl-6, Caspase-3, and cognitive decline deficits. This study highlights the harmful neurotoxic amplification of T2DM and ACY exposure, emphasizing the importance of public health measures to reduce ACY exposure through dietary and lifestyle changes, particularly among T2DM populations. Further research into neuroprotective strategies and underlying mechanisms is necessary.
