RESUMEN
After cardiovascular diseases, cancer is the second main cause of death globally. Mushrooms have been demonstrated to contain amalgamation with properties capable of inhibiting carcinogenesis and microbial growth, principally secondary metabolites such as quinolones, steroids, terpenes, anthraquinones, and benzoic acid derivatives among others. This study aimed to substantiate their potency concerning colon cancer carcinogenesis and antimicrobial growth. A systematic search of important literature was performed considering all the articles published until April 2022. Screening was performed by searching the BMC Springer, Elsevier, Embase, Web of Science, Ovid, and MEDLINE databases. In addition, Google Scholar was used to supplement information. Titles and abstracts that matched the established criteria were selected for full-text article scrutiny and subsequently used in the updated present review. Bioactive compounds present in medicinal mushrooms such as ascorbic acid, organic acids, flavonoids, polysaccharides, glycosides, phenols, linoleic acid, grifolin, and tocopherols among other compounds play a key role in suppressing the proliferation of cancerous cells and selectively act as antibacterial and antifungal agents. These metabolites actively scavenge oxygen free radicals, hydroxyl radicals, and nitrite radicals that would otherwise increase the risks of the growth and development of cancerous cells. Mushrooms' bioactive compounds and metabolites actively inhibit nuclear factor-kappa activation, protein kinase B processes, and ultimately the expression of Cyclooxygenases 2 in cancerous cells. Medicinal mushrooms should be considered as alternative natural chemo-preventive agents in the global fight against colon cancer and the evolution of drug-resistant pathogenic microorganisms, as they exhibit robust potency. They have not been reported to exhibit adverse harmful effects compared to synthetic chemotherapies, yet they have been reported to demonstrate significant beneficial effects.
RESUMEN
BACKGROUND AND PURPOSE: The shift work is burdensome for nurses and may lead to health problems. Aims - The purpose of the study was to examine the nursing shift system types and to analyse the effects on nutritional status, subjective state of physical and mental health in case of different shift schedules. METHODS: In the first phase of the research 326 nurses working in changing shifts filled out the Bergen Shift Work Questionnaire after adaptation into Hungarian. 518 nurses participated in our second study in hospitals of the South-Danubian Region, in clinics of University of Pécs and at trainings organized by the Faculty of Health Sciences of the University of Pécs. RESULTS: Based on the psychometric characteristics of Bergen Shift Work Questionnaire technically it is suitable for the examination of sleeping disorders associated with shift work. Sleeping quality is worse in those working in irregular work shifts compared to those working in regular and flexible work schedules (p<0.001). The irregular work schedule is worse than the regular work schedule according to 76.6% of the nurses. According to 63.8% of the respondents the following regular work schedule is the best: after one 12-hour day shift one 12-hour night shift, followed by two days of rest. The average Body Mass Index (BMI) is 26.16 kg/m2. Since the nurses work in shift work 47.7% of them reported weight gain. Among the psychosomatic symptoms the most frequent is back pain (78.4%) related elevated BMI (p=0.013). The nurses' sense of coherence on average is 61.76 points. In case of full-time employees the sense of coherence is better than those who work in shifts (t=2.933, p=0.004). The nurses working irregular shift work asses their health worst (mean rank: 166.61; p=0.019), and their sense of coherence is lower (p=0.04). CONCLUSION: The irregularity of work schedules is stressful for nurses. Due to the health of nurses it would be useful to establish the least exhausting work schedules.

Colon tumors have a very complicated and poorly understood pathogenesis. Plant-based organic compounds might provide a novel source for cancer treatment with a sufficient novel mode of action. The objective of this study was to analyze and evaluate the efficacy of Aloe secundiflora's (AS) methanolic extracts on the expression of CASPS9, 5-LOX, Bcl2, Bcl-xL, and COX-2 in colorectal cancer (CRC) management. Caco-2 cell lines were used in the experimental study. In the serial exhaustive extraction (SEE) method, methanol was utilized as the extraction solvent. Upon treatment of CASPS9 with the methanolic extracts, the expression of the genes was progressively upregulated, thus, dose-dependently increasing the rate of apoptosis. On the other hand, the expressions of 5-LOX, Bcl2, and Bcl-xL were variably downregulated in a dose-dependent manner. This is a unique novel study that evaluated the effects of AS methanolic extracts in vitro on CRC cell lines using different dosage concentrations. We, therefore, recommend the utilization of AS and the application of methanol as the extraction solvent of choice for maximum modulatory benefits in CRC management. In addition, we suggest research on the specific metabolites in AS involved in the modulatory pathways that suppress the development of CRC and potential metastases.
RESUMEN
The evaluation of natural biomass sources is a promising strategy in accelerating the development of novel anti-cancer medications. Our study aimed to evaluate the activity of W. ugandensis ethanolic roots and stems extracts on the expression of five targeted genes (COX-2, CASPS-9, Bcl-xL, Bcl2 and 5-LOX) in colorectal cancer (CRC) cell lines (Caco-2). Plant extracts were obtained using serial exhaustive extraction and dissolved in Dimethyl sulfoxide appropriately for bioassay. Caco-2 cell lines were passaged, treated with plant extracts at varying concentrations and their RNA's isolated for evaluation. Our unique study reports on W. ugandensis as efficient natural inhibitors of CRC growth, by directly linking its phytoconstituents to; downregulation of COX-2, 5-LOX, Bcl-xL, Bcl2 and upregulation of CASPS9 genes dose-dependently. We present W. ugandensis ethanolic roots and stems extracts as promising natural inhibitors for CRC carcinogenesis and recommend in vivo and subsequent clinical trials, with substantial clinical effects postulated. We further suggest studies on identification and characterization of the specific metabolites in W. ugandensis involved in the modulatory mechanisms, resulting to inhibition of CRC growth and possible metastases.

Aloe species are widespread and diverse in African ecosystems, and this commonly correlates to their habitual use as reservoirs of herbal medicine. The side effects associated with chemotherapy and the development of antimicrobial resistance to empirically used antimicrobial drugs are substantial, paving the way for novel phytotherapeutic approaches. This comprehensive study aimed to evaluate and present Aloe secundiflora (A. secundiflora) as a compelling alternative with potential benefits in colorectal cancer (CRC) treatment. Important databases were systematically searched for relevant literature, and out of a large collection of 6421 titles and abstracts, only 68 full-text articles met the inclusion criteria. A. secundiflora possesses an abundant presence of bioactive phytoconstituents in the leaves and roots, including anthraquinones, naphthoquinones, phenols, alkaloids, saponins, tannins, and flavonoids, among others. These metabolites have proven diverse efficacy in inhibiting cancer growth. The presence of innumerable biomolecules in A. secundiflora signifies the beneficial effects of incorporating the plant as a potential anti-CRC agent. Nonetheless, we recommend further research to determine the optimal concentrations necessary to elicit beneficial effects in the management of CRC. Furthermore, they should be investigated as potential raw ingredients for making conventional medications.
RESUMEN
Recently, online education has been gaining prominence in university life. Our survey aimed to examine sleep quality and perceived stress levels among students at the University of Pécs Faculty of Health Sciences. A cross-sectional, quantitative, descriptive survey was conducted between February and March 2023. The online survey included the Hungarian versions of the internationally validated Athens Insomnia Scale (AIS) and Perceived Stress Scale (PSS). Statistical analysis involved descriptive statistics, independent t-tests, analysis of variance (ANOVA), and Mann-Whitney and Kruskal-Wallis tests (p < 0.05). We analyzed 304 responses, and females dominated (n = 270; 88.8%). Students in a relationship had significantly higher AIS scores (t = -2.470; p = 0.014). Medium average (2.50-3.49) students and those who rarely/never exercise showed significantly higher AIS and PSS (p ≤ 0.05). Students on the phone/watching a series during online education, daily laptop/TV use for more than 2 h, and pre-sleep use of smart devices for more than 60 min also negatively affected AIS and PSS scores (p ≤ 0.05). Nursing, physiotherapy, and radiography students were the most affected regarding insomnia and perceived stress (p ≤ 0.05). Our survey shows that excessive smart device use and lack of exercise are associated with higher stress levels and poorer sleep quality.
RESUMEN
Development and identification of molecular compounds capable of killing or inhibiting transformed cells promoting carcinogenesis without inducing toxic effects to the normal cells are of utmost significance. A systematic review was conducted in screening for important literature was extensively performed by searching the Web of Science, Ovid, BMC Springer, Elsevier, Embase, and MEDLINE databases for optimum selectivity. Google Scholar was also used to supplement information. Pharmacotherapeutic biomolecules active against colon cancer carcinogenesis in Musa acuminata and Musa balbisiana (bananas), Punica granatum L (pomegranate), Glycine max (Soybean), Brassica oleracea L var. italica Plenck (Broccoli), and Hibiscus rosa-sinesis and Hibiscus sabdariffa (hibiscus) were evaluated. Signaling pathways like phosphatidylinositol 3-kinase (PI3K), mitogen-activated protein kinase (MAPK), protein kinase B (AKT), and nuclear factor-kappa B (NFκB) correlate the mediation of COX-2 expression. Increased levels of COX-2 are correlated with the occurrence and progression of colon cancer. Natural antioxidants in herbal plants including polyphenols and carotenoids inhibit the oxidation of lipids, proteins, and nucleic acids and thereby preventing the initiation of oxidizing chain reactions. These bioactive compounds should be considered an important dietary supplement.

The development of effective, safe, and acceptable vaccines is a long process. COVID-19 vaccine hesitancy continues to elicit mixed reactions among different quarters despite numerous evidence of their effectiveness. This study aimed to determine the availability and acceptance rates of SARS-CoV-2 vaccines, among Kenyan and Hungarian residing populations and the underlying reasons contributing to the hesitancy of uptake. A non-probability, snowball sampling design was employed, and a survey questionnaire tool link was expeditiously disseminated. Data were carefully analyzed descriptively. Demographic variables, COVID-19 awareness, possible exposure, reasons associated with hesitancy in taking up a vaccine, choice of a vaccine, and availability of vaccines among other important variables were tested to explore their associations with vaccine acceptance rates between the two distinct countries. A total of 1960 participants were successfully enrolled in the research study, while 67 participants were excluded based on the inclusion criterion set. There was, however, no significant difference in COVID-19 public awareness between the Kenyan and Hungarian-residing participants, p = 0.300. Of the respondents, 62.4% were willing and ready to receive vaccines against COVID-19 disease. There was a significant difference (p = 0.014) between the Kenyan and Hungarian-residing respondents concerning vaccine uptake and acceptance rates. The vaccine acceptance rates in Hungary were higher than in Kenya, with mean = 0.27, SD = 0.446, S. E = 0.045 for the Hungarian population sample and mean = 0.40, SD = 0.492, S. E = 0.026, for the Kenyan sample respectively. Concerning gender and vaccine acceptance, there was a notable significant difference between males and females, p = 0.001, where the mean for males and females were 0.29 and 0.46 respectively. Acceptance rates among males were higher than among females. The functions of One-Way ANOVA and Chi-square were used to establish any significant differences and associations between means and variables respectively. Concerns regarding the safety, efficacy, and accuracy of information about the developed vaccines are significant factors that must be promptly addressed, to arrest crises revolving around COVID-19 vaccine hesitancy, especially in Kenya and among females in both populations, where acceptance rates were lower. Expansion of the screening program to incorporate antibody (serology) tests, is also highly recommended in the present circumstance. Equitable distribution of vaccines globally should be encouraged and promoted to adequately cover low- and middle-income countries. To enhance effective combat on vaccination hesitancy and apprehension in different countries, mitigation techniques unique to those countries must be adopted.
