Published: December 2024

Objective
To construct the risk prediction model of COVID-19 infection in FS.
Methods
Ninety children with FS were included, and the clinical data were collected for univariate regression analysis. The predictive factors for the risk of infection of COVID-19 were screened by LASSO regression analysis. The predictive model was constructed by nomogram, and verified by the ROC curve.
Results
The median ages of children in the COVID-19 and non-COVID-19 group were 5.0 and 3.3 years, respectively. And there was males dominance in the COVID-19 group compared with non-COVID-19 group (p = 0.0174). The history of FS was more common in the non-COVID-19 group than in the COVID-19 group (p = 0.0146). The blood white blood cells levels (p < 0.0001), lymphocyte levels (p < 0.0001) and serum sodium levels of the COVID-19 group were lower than those of the non-COVID-19 group (p = 0.0098). The proportion of myelin sheath immature in the non-COVID-19 group was lower than that in the COVID-19 group (p = 0.0121). The LASSO regression analysis revealed gender (Coef.:-0.63586571), age (Coef.:0.60214948), lymphocyte levels (Coef.:-0.6587662), serum sodium levels (Coef.:-0.01968962), normal head MRI (Coef.:4.43661865), Other pathogen infection (Coef.:-3.2293900) and history of FS (Coef.:-3.18077790) were all predictive variables of COVID-19 infection risk. The predictive model was established by the above seven predictive variables, and the model discrimination was verified by AUC of the ROC curve. The traindata AUC was 0.965, testdata AUC was 0.864, and the slope of the correction curve was close to 1.
Conclusion
Male, elderly children, hyponatremia, and decreased lymphocyte levels indicated an increased probability of COVID-19 infection.

Authors: Balakosy Amira Mahmoud Al , Mohamed Marwa Ahmed , Hassan Azza , Badran Ethar Mokhtar
Published: December 2024

Background and Aim: Health-related quality of life (HRQoL) is a multidimensional concept encompassing the physical, psychological, and social domains of health. Inactive hepatitis B virus (HBV) carriers although apparently healthy have a lifelong chronic infection that might impose different challenges on their daily life. Understanding these impacts helps clinicians address the broader consequences of the disease on patients' well-being.
Objectives: This study aimed to evaluate the HRQoL of HBV carriers compared to healthy controls using the World Health Organization Quality of Life-BREF (WHO-QOL-BREF) scale and to identify the most affected domains in HBV carriers
Patients and Methods: This a cross sectional prospective study where Chronic HBV patients attending to Viral Hepatitis outpatient clinic (OPC) at Ain Shams University were enrolled if they fulfilled criteria of chronic carrier state, undetectable or low (<2,000 IU/ml) HBV DNA levels and normal ALT (ULN <40 IU/L), healthy controls without past history of chronic illnesses were also included. To evaluate HRQL the World Health Organization Qualify of Life Assessment Instrument, Short Version (Arabic WHOQOL Bref) questionnaire was used. Scores were analyzed and compared between the two groups.
Results: 60 patients with chronic HBV infection proved to be in the carrier state by low viremia in whom HBV quantitative PCR was negative in 10 carriers (16.7%) and positive in 50 carriers the mean of which was 431±512), AST and ALT were within the normal range (20±7 and 20±9 IU/ML) respectively. The majority were females (62%) the mean of their age was 41±9 years, 55% had at least primary education, most of them were married (90%) and (36.7%) were housewife. The total score of HRQL in HBV carriers (77±19) is significantly lower than healthy controls (86±12) (p=0.001). In carriers the scores of the physical (23.5± 7), psychological (19±4.6) and environmental (22.5 ±6.3) domains were significantly lower compared to controls (29 ±4, 21 ±3 & 26 ±6) (p<0.001, p=0.001 &p=0.004) respectively and the highest difference was recorded in the physical domain. Factors such as age, co-morbidities, and laboratory findings did not significantly influence the overall QOL scores; however, females had lower scores in the psychological domain compared to males (p = 0.05).
Conclusion: HBV carriers have impaired quality of life & the physical function is mainly affected.
Preoperative computed tomography assessment of peri-hip muscles in patients with femoral neck fracture and its impact on postoperative walking function
Authors: Yokoyama Katsuya , Ukai Taku , Ogawa Makoto , Watanabe Masahiko
Published: December 2024

Background
The role of preoperative peri-hip muscles in postoperative walking ability for patients with femoral neck fractures is unclear. This study aimed to investigate the influence of these muscles on postoperative walking function using computed tomography (CT).
Methods
A retrospective analysis was conducted on 58 patients (12 male, 46 female) who underwent bipolar hemiarthroplasty for femoral neck fractures between January 2018 and July 2021. Patients were followed up for at least six months postoperatively and divided into two groups: the independent walking group (41 patients) and the non-walking group (17 patients). Patient data, including sex, age at surgery, body mass index (BMI), and preoperative walking status, were compared. Additionally, preoperative CT scans assessed the cross-sectional areas and CT values of the gluteus medius, gluteus maximus, and rectus femoris muscles on the unaffected side. These measurements were compared between the two groups.
Results
No significant differences were observed between the groups regarding sex, age, BMI, or preoperative walking status. The CT values of the gluteus medius and gluteus maximus were significantly lower in the non-walking group (P < 0.01), while no significant differences were found for the rectus femoris. Cross-sectional areas of all of the muscles did not show significant differences. In ROC curve analysis, the gluteus medius had an AUC of 0.86, with a sensitivity of 0.78 and specificity of 0.82, using a cut-off of 33.1 Hounsfield units (HU). The gluteus maximus had an AUC of 0.77, with a sensitivity of 0.63 and specificity of 0.77, using a cutoff of 31.6 HU.
Conclusions
Preoperative CT values of the gluteus medius and gluteus maximus were lower in the non-walking group, suggesting that these muscles influence postoperative walking ability. Preoperative CT evaluation of these muscles can be a useful predictor of postoperative walking outcomes.

Authors: Pan Mengshan , Yin Tongle , Yang Ying , Zhu Feiyun , Xu Jiamin , Chen Rucheng , Zheng Weijun
Published: December 2024

Background
Four dietary patterns were linked to lower mortality rates in cardiovascular patients. This study investigated the relationship between these dietary patterns and mortality risk in U.S. cardiovascular patients from 2005–2006 to 2017–2018.
Methods
Data were collected from adults aged 19 years and older participating in the National Health and Nutrition Examination Survey (NHANES, N = 3475) from 2005–2006 to 2017–2018. Dietary patterns were assessed for each survey cycle using 24-hour dietary recalls, and scores for the four dietary indices were calculated.Survey-weighted multivariable Cox proportional hazards regression models were applied to evaluate the associations between the four dietary indices and overall mortality risk, as well as cause-specific mortality in cardiovascular disease patients.
Results
Among 3475 cardiovascular patients, the weighted mean age was 65.03 years (SE = 0.35). In partially adjusted models, the Planetary Healthy Diet Index-United States (HR = 0.986, 95% CI: 0.981–0.991, P < 0.001), Healthy Eating Index (HR = 0.992, 95% CI: 0.987–0.997, P = 0.003), and Mediterranean Diet Score (HR = 0.879, 95% CI: 0.806–0.959, P = 0.004) were associated with a reduced risk of death. Conversely, the Dietary Inflammation Index was linked to an increased risk of death (HR = 1.140, 95% CI: 1.081–1.203, P < 0.001). In fully adjusted models, the Planetary Healthy Diet Index-United States (HR = 0.992, 95% CI: 0.986–0.998, P = 0.007) and Dietary Inflammation Index (HR = 1.093, 95% CI: 1.036–1.152, P = 0.001) remained significantly associated with mortality risk.
Conclusions
Results indicated that in cardiovascular patients, higher Healthy Eating Index, Mediterranean Diet Score, and Planetary Healthy Diet Index-United States (PHDI-US) were associated with reduced mortality, whereas a higher Dietary Inflammation Index (DII) was linked to increased mortality. The Dietary Inflammation Index (DII) score was strongly associated with mortality risk in patients with coronary heart disease or stroke, while the Planetary Healthy Eating Index (PHDI-US) score was closely associated with mortality risk in patients with congestive heart failure, coronary heart disease, and angina pectoris.
Uninhabitable cities: urban temperatures outside the climate niche in 2100
Authors: Friesen John , Taubenböck Hannes
Published: December 2024

This study evaluates the projected impacts of future temperature increases on urban populations across 1,500 cities with over 300,000 inhabitants globally. By integrating downscaled climate data, population projections, and urban morphology, we identify cities at risk of surpassing the 29°C threshold of mean annual temperature, marking the upper limit of the human climate niche. Under three climate scenarios (SSP126, SSP370, and SSP585), our projections for 2100 suggest that 29 cities (SSP126) to 215 cities (SSP585), housing approximately 60 million (SSP126) to 446 million (SSP370) people, may exceed this critical threshold. These findings underscore the challenges for urban livability, particularly in regions such as Africa, South America, and Asia.
Exploring natural variability in the mulberry (Morus indica) cultivar, Kanva-2 through clonal selection
Authors: R RAVI KUMARA , H.B. MANJUNATHA
Published: December 2024

Mulberry (Morus spp.) is a crucial plant in sericulture, serving as the sole food source for the silkworm, Bombyx mori. Clonal selection in mulberry is a strategic approach to leveraging natural variability for the development of improved cultivars. This method enables the identification and propagation of superior clones that exhibit desirable traits, such as enhanced leaf quality, growth vigor, and adaptability to varying environmental conditions. In the present study; we identified 11 clonal variants from the cultivar Kanva-2 (K-2) through field surveys. These clonally selected genotypes were designated as CS-1, CS-2, CS-3, CS-4, CS-5, CS-6, CS-7, CS-8, CS-9, CS-10, and CS-11, and underwent detailed characterization of their morphometric and molecular traits. The clonally-derived genotypes exhibited distinct features compared to their mother plant, K-2. Notably, genotypes CS-1, CS-4, CS-5, and CS-6 demonstrated improved leaf yield and quality traits, highlighting their potential advantages over the original cultivar. These genotypes can be utilized in breeding programs or to enrich germplasm resources.
Fluid chemistry and circulation patterns from typical convective hydrothermal system on the northeastern Tibetan Plateau
Authors: Yang Lu , Lu Rui , Liu Bo , Xie Wenping , Zhu Jinshou , Lin Wenjing
Published: December 2024

The northeastern Tibetan Plateau is abundant with intermediate to low-temperature geothermal resources, with hot springs varying significantly among locations and tectonic conditions. Understanding the causes of these differences is crucial. This research specifically examines the Wahongshan-Wenquan Fracture Zone (Area Ⅰ) and the Zhiduo-Yushu Mountainous Zone (Area Ⅱ) in Qinghai Province. Hydrochemical and gas isotope data were collected from convective hydrothermal systems in these distinct tectonic settings. A comparative analysis of geothermal fluid geochemical characteristics and sources was conducted using fluid geochemistry methods. Results show that hot water in the igneous rocks of Area Ⅰ is mainly of Cl-Na type, while in the carbonate rocks of Area Ⅱ, it is primarily of HCO3-Ca•Mg type. The salts in the former come from silicate mineral dissolution, while the solutes in the latter are primarily influenced by carbonate rock breakdown. Igneous thermal reservoirs have higher temperatures and greater fluid circulation depths than carbonate reservoirs. Geothermal gases in both regions are dominated by N2 of atmospheric origin. Most of He originates from the crust, with mantle contributions not exceeding 5%. High CO2 content (14%) in certain carbonate reservoirs is mainly of inorganic metamorphic origin. Both regions are medium-low temperature convective geothermal systems, primarily driven by crustal heat. However, isotopic analysis suggests that the carbonate reservoirs in the Zhiduo-Yushu Mountains have a higher mantle contribution than those in the Wahongshan-Wenquan Fracture Zone. This study summarizes the fluid circulation patterns in these two regions, revealing regional and tectonic influences on fluid sources and transport mechanisms. It provides a theoretical framework for developing and utilizing geothermal assets on the northeastern Tibetan Plateau.
Photoexcited Hole and Electron-Polaron Entangled Photocatalytic Reaction on Metal Oxide Surface
Authors: Zhao Jin , Gao Chang , Tan Shijing , Chu Weibin , Wang Bing , Petek Hrvoje , Zheng Qijing
Published: December 2024

Analyzing dynamics at both temporal and spatial scales of surface photocarrier interactions is pivotal for optimizing the photocatalytic chemical activity. Taking the photocatalytic conversion of CH3OH to HCOOCH3 on TiO2 surface as a prototypical system, we elucidate the correlated time- and spatial- evolution of photoexcited electron-hole (e-h) pairs, defining the polaron-catalyzed molecule-surface chemistry at the ab initio theory level. The photocatalytic process is driven by two photoexcited holes, each inducing C-H bond cleavage via a proton coupled electron transfer (PCET). It leads to the formation of HCOOCH3, with a pair of protons adsorbed on bridge oxygen atoms and the release of two electrons, forming two small polarons. The entire reaction occurs on picosecond timescale. Photoexcited electrons do not directly participate in the reaction but form small polarons in TiO2 within tens of femtoseconds, which lowers reactant energy and suppress the photocatalytic efficiency. This study illuminates novel insights on the design and optimization of surface photocatalytic reactions.
NIPBL 5'UTR Mutation: A Molecular Switch in Cohesin Complex- Related CdLS
Authors: Chen Qingqing , Chen Yonghua , Zou Chaochun , Wang Chunlin
Published: December 2024

Cornelia de Lange Syndrome (CdLS) is a prevalent cohesinopathy, frequently arising from mutations in genes encoding components of the cohesin complex, with NIPBL being the most commonly affected. This study aimed to investigate the consequences of a 5' untranslated region (UTR) mutation (c.-467 C > T) in the NIPBL gene on gene expression, cohesin complex integrity, and cellular development. Utilizing CRISPR/Cas9 technology, we generated a heterozygous cell line harboring the NIPBL 5'UTR mutation and employed a suite of molecular biology techniques, including RNA secondary structure prediction, luciferase reporter assays, and RT-pcr, to evaluate the mutation's impact. Our findings indicate that the 5'UTR mutation introduces an additional upstream open reading frame (uORF), resulting in diminished mRNA and protein expression levels of NIPBL. This reduction in NIPBL expression correlated with a downregulation of RAD21, a pivotal component of the cohesin complex, and a decrease in nuclear β-catenin levels, thereby affecting cell proliferation. This study elucidates that the 5'UTR mutation in NIPBL contributes to CdLS by disrupting gene expression and cellular processes, underscoring the significance of 5'UTR elements in the regulation of gene expression and the potential ramifications of sequence variations within this region. Our results advance the understanding of the molecular mechanisms underlying CdLS and may inform the development of targeted therapeutic interventions.

FTLinear: MLP based on Fourier Transform for Multivariate Time-series Forecasting
Authors: Ouyang Junjie , Li Yan , Pan Qijing
Published: December 2024

Most existing multivariate time series forecasting models are based on Recurrent Neural Networks(RNNs), Graph Neural Networks(GNNs), and Transformers, which leads to high model complexity. Although linear models based on Multi-layer Perceptrons(MLPs) have the advantages of low complexity and high performance, they fail to capture the long-term dependencies in time series, resulting in poor forecasting performance. This paper proposes a linear model based on Fourier Transform, FTLinear, which first converts the time series to the frequency domain, then uses frequency enhancement to remove noise from the data, and finally obtains the output through a simple linear transformation. Experimental results show that the proposed model improves MSE and MAE by 18.48% and 8.03% respectively compared to iTransformer, by 12.03% and 2.35% respectively compared to PatchTST, and by 17.75% and 7.52% respectively compared to DLinear on 8 public datasets. This demonstrates that converting time series to the frequency domain can provide the model with a global perspective, enhancing its ability to capture long-term dependencies and thus improving forecasting performance.

Published: December 2024

Introduction: Consumers with personality disorder/vulnerabilities and their carers may not always receive appropriate, compassionate care through health services.
Aim/Question: To study experiences of the emergency department, inpatient and outpatient services from the perspectives of people with lived experience of personality disorder/vulnerabilities.
Method: Twenty consumers, carers and peer workers with lived experience of personality disorder/vulnerabilities participated in focus groups. Responses were analysed using reflexive thematic analysis.
Results: Peer support was described as a positive way to support consumers with personality disorder/vulnerabilities and their carers. In contrast, experiences of traditional crisis services were mixed with some consumers and carers experiencing helpful responses and others dismissive responses from clinicians. Crisis services for personality disorder may be improved by the provision of peer support, continuity of care and appropriate discharge referrals.
Discussion: Negative experiences of crisis care show a need for improved care for personality disorders/vulnerabilities in emergency department and inpatient settings.
Evaluation of functional-technological and organoleptic properties of cooked sausages with the addition of hemp oil
Authors: Synytsia Olha , Shlapak Halyna
Published: December 2024

The use of vegetable oils as a source of polyunsaturated (omega-3 and omega-6) fatty acids in the production of meat products has been considered in order to increase their nutritional and biological value.
The issue of partially replacing pork fat in the minced meat cooked sausage with hemp seed oil has been investigated without deteriorating functional-technological and consumer properties, such as taste, aroma and color of the product, water-binding capacity and weight loss after temperature treatment, was investigated.
The work studied samples of cooked sausages with a replacement of pork fat with hemp oil in amounts of 1 %, 3 %, 5 %, and 7 %. The hemp oil was added at the second stage of minced meat cutting in its pure form or in an emulsion state. The emulsion with hemp oil was prepared in a ratio of protein:oil:water 1:5:5. Soy protein was used for a stable emulsion.
It has been proven that the addition of hemp oil in its pure form practically does not change the pH of minced meat, and the addition of oil in the emulsion increases the value of active acidity in the alkaline direction.
 When adding oil in the amount of 5...7 % in the state of emulsion, the water-binding capacity increased by 2.4...2.9 % compared to the control sample. The addition of oil in its pure form slightly reduced the water-binding capacity of the samples with 5 % and 7 % oil compared to the control sample by 0.2 % and 0.4 %, respectively.
Based on the results of organoleptic studies, the addition of hemp seed oil in the form of an emulsion in the amount of 3...5 % is proposed.
The obtained results prove the prospects of using hemp seed oil in the form of an emulsion in the composition of cooked sausages to improve the nutritional and biological value, enrich the product with unsaturated fatty acids and increase the yield after heat treatment
Research of quality indicators of jelly from rowan powder
Authors: Samilyk Maryna , Illiashenko Yana
Published: December 2024

The object of the study is the quality indicators of jelly from a concentrate based on Aronia powder rowan powder. The aim of the study is to substantiate the feasibility of using rowan powder for the production of natural food concentrate. A method for obtaining a concentrate and a finished jelly dish based on rowan powder is proposed and their quality indicators are analyzed. The method for producing Aronia powder rowan peas involved preliminary dehydration of the fruit (Aronia melanocarpa) by osmotic dehydration, drying and grinding into a fine structure. Recipes for prototype jelly samples based on rowan powder R1 (83 %), R2 (77 %) were developed and their organoleptic and physicochemical quality indicators were analyzed. The results of the study showed that the jelly concentrate from rowan powders in appearance was a homogeneous granular mixture, which is typical for this type of product. It was found that the concentrate contains 1.45 % fiber. However, the appearance of the finished jelly was rated "moderately good" as the dish was cloudy. The lack of transparency is explained by the high content of minerals in its composition (3∙10–2 %). The dish had a dark purple color, characteristic of rowan, and a sour-sweet taste and smell. Due to osmotic dehydration, no astringency was felt. It had a uniform jelly-like consistency and retained its shape on a horizontal surface. The jelly contained a significant amount of titrated acids (2.3 % in terms of citric acid) and vitamin C (6.8 mg/100 g), which is associated with their high content in chokeberry fruits. The presence of fiber, glucose and fructose in the concentrate has a positive effect on the biological value of the product
Wisdom of honey bees: colony foraging is governed by colony needs
Authors: Sihag Ram Chander
Published: December 2024

Honey bees visit the flowers for two essential nutritional requirements, viz., pollen and nectar. Sometimes the foraging bees collect more nectar, whereas at other times they collect more pollen. What makes them take such decisions has been the interest of many honey bee scientists. The objective of this article was to find out about the drivers causing such changes in the foraging decisions of the honey bee colony. The published literature was examined to find an answer to this question. For this, published research on foraging behavior of honey bees was scanned on different search engines. From the published reports, it has become evident that for making a choice between these two food sources, a high level of colony wisdom is involved. Sometimes the colony engages in brisk pollen collection, whereas on other occasions it engages in brisk nectar collection. Given the scarcity of a particular food type in the colony, the latter takes immediate and wise decisions. The colony makes these changes in the foraging decision depending on the needs of the colony. For example, with the addition of the unsealed brood and honey stores in the colony, the latter increases pollen foraging and decreases nectar foraging activity. However, with the addition of the sealed brood, the colony does not significantly change foraging activity. Likewise, with the addition of pollen stores, the honey bee colony decreases pollen foraging and increases nectar foraging activity. However, these colony decisions are not long-lasting. After some 20 days, the colony resumes its normal behavioral plasticity of usual nectar and pollen foraging activity. This knowledge of honey bee wisdom regarding its foraging decisions will be highly useful in colony management for honey production and/or pollination of crops

Published: December 2024

Tomato production in Cameroon faces numerous constraints, including post-harvest rot. This study was carried out with the aim of contributing to the fight against post-harvest rot of tomato fruits through the use of the aqueous extract of Ageratum conyzoides. To achieve this objective, the pathogen responsible for tomato fruit rot was isolated and the microscopic and macroscopic characters determined; the antifungal activity of the aqueous extract of A. conyzoides was evaluated in vitro using three doses (30, 60, and 120 mg/ml) with three repetitions at three different periods (before, during and after) fruit treatment by the extract and inoculation of the pathogen on scarified and non-scarified fruits. A synthetic fungicide Pencozeb served as a positive control. Parameters such as mass loss of tomato fruits, surface area of lesions induced on scarified and non-scarified tomato fruits, were measured using a balance and graph paper respectively. The results show that Fusarium oxysporum was the pathogen responsible for rotting tomato fruits and having the macroscopic characteristic of a cottony texture and a white aerial mycelium, macroscopically, Fusarium oxysporum presents two types of asexual spores, namely macroconidia which are curved, pale-colored spores, and microconidia which are ovoid spores with septate and branched hyphae, a smooth and thin cell wall. The antifungal test revealed that the aqueous extract showed an effect inhibitor on the development of the lesion surface and mass loss at the highest dose 120 mg/ml when the extract applied twenty-four hours (24 hours) before inoculation on the fruits was fungicides at a concentration of 120 mg/ml on Fusarium oxysporum. The pathogen-induced lesion area and mass loss of scarified tomato fruits were 6.000±3.09 and 10.04±9.37 respectively. In non-scarified fruits these values were 8.45±3.43 and 48,000±13.66 respectively for lesion area and mass loss. This extract can therefore be used as an alternative to chemical pesticides in fruit preservation

Published: December 2024

Hands of healthcare workers are the most common vehicle for the transmission of healthcare-associated pathogens from patient to patient and within the healthcare environment. This study aimed to assess the level of hand hygiene compliance and its predictors among healthcare providers working in primary healthcare settings in the Girawa District, Eastern Ethiopia. A facility-based cross-sectional study was conducted from November 1 to December 1, 2023 among 398 randomly selected healthcare providers. Data summary statistics, bivariate, and multivariable logistic regression models were used. Adjusted odd ratio, 95% confidence interval (95% CI), and p-value of <0.05 was used to identify predictors of hand hygiene compliance among healthcare providers. In this study, the overall hand hygiene compliance was 30.15% [95% CI (25.68–34.92)]. Being trained about hand hygiene, having a BSc degree, availability of handwashing facility setup in working room, knowledge about hand hygiene and having good hand hygiene were significantly associated with hand hygiene compliance. Limited knowledge and lack of water, sanitation, and hygiene (WASH) facilitates have significant influences for health workers’ hand hygiene compliance. Hence, the primary healthcare settings should be equipped with adequate supply to all the basic hand hygiene facilities and build staff capacity in WASH through periodic training.

Published: December 2024

Objectives:

The Enhanced Recovery After Surgery (ERAS) program is a multidisciplinary approach aimed at minimizing postoperative complications,
shortening hospital stays, and improving clinical outcomes. The current study assesses the knowledge, attitudes, and practices (KAP) of nurses and
anesthesia technicians regarding the ERAS program, which is essential for evaluating their understanding and readiness to implement the program,
as well as identifying factors influencing the successful adoption of ERAS in clinical practice.

Methods:

The cross-sectional study involved nurses and anesthesia technicians with at least two months of experience at the University Medical Center in Ho
Chi Minh City, Vietnam. A validated questionnaire assessed their KAP regarding the ERAS program. Data were collected via electronic surveys
during ERAS group meetings and analyzed with Stata 16.0. The Wilcoxon and Kruskal-Wallis tests compared qualitative variables, while
Spearman regression identified relationships between quantitative variables.

Results:

Among the 193 nurses and anesthesia technicians, knowledge and attitude scores towards the ERAS program were highly rated, with mean scores
of 7.66 ± 1.46 and 40.10 ± 5.24, respectively. Their mean practice score was 6.51 ± 1.26. Age, work experience, and educational level significantly
influenced the participant's knowledge, attitudes, and practices. Additionally, there was a positive correlation between attitude and practice (p <
0.001).

Conclusion:

This study shows that nurses and anesthesia technicians possess the knowledge and a positive attitude toward the ERAS program; however, their
practices remain limited. These results highlight the importance of continuous training and professional development to enhance the effectiveness
of ERAS implementation in clinical practice.

Rhythmicity is a characteristic feature of the inanimate universe. The
organization of biological rhythms in time is an adaptation to the cyclical environmental
changes brought on by the earth's rotation on its axis and around the sun. Circadian
(L. Circa= "around or approximately"; diem = "a day") rhythms are biological
responses to the geophysical light/dark (LD) cycle in which an organism adjusts to
alterations in its internal physiology or external environment as a function of the time of
day. Sleep has been considered a biological rhythm. Normal human sleep, an
essential physiologic process, comprises two distinct phases: non-rapid eye movement
(NREM) sleep and rapid eye movement (REM) sleep. A mature adult human's
sleep/wake cycle displays a circadian rhythm with a ~24-hour cycle. According to the
two-process model of sleep regulation, the human sleep/wake cycle is orchestrated by
circadian and homeostatic processes. Sleep homeostasis (a sleep-dependent
process) and circadian rhythm (a sleep-independent process) are two biological
processes controlling the sleep/wake cycle. There are also ultradian (< 24-hour)
rhythms, including the NREM-REM sleep cycle, which has been extensively studied.
The clock and sleep genes both influence sleep. In this overview, we have reviewed
the circadian genes and their role in regulating sleep. Besides, the gene expression
and biological pathways associated with sleep and circadian rhythm-associated
diseases also have been highlighted.

Published: December 2024

Background:

Among the bioactive isoflavones identified from different plants
is formononetin. Formononetin's antioxidant, anti-inflammatory, and anti-cancer qualities
have all received a lot of attention lately. The goal of the current investigation was to examine
formononetin's antifungal and antibacterial activity against Candida albicans and
Enterococcus faecalis in vitro, respectively.

Methods:

The present study determined the Minimum Inhibitory Concentration (MIC),
Minimum Bactericidal Concentration (MBC), and Minimum Fungicidal Concentration
(MFC) of formononetin, chlorhexidine, formononetin + chlorhexidine, Formononetin+
nystatin, and nystatin against E. faecalis and C. albicans isolates. Next, SPSS version 25
was used to analyze the data. A significance cutoff of P<0.05 was taken into account.

Results:

Chlorhexidine + formononetin and formononetin alone had the greatest and
lowest minimum inhibitory concentrations (MIC) against E. faecalis, at 6.6 and 18.3
μg/ml, respectively. With MIC values of 0.66 and 8.3 μg/ml against a C. albicans isolate
sensitive to nystatin, the combination of formononetin + nystatin and formononetin alone
was shown to have the greatest and lowest anti-candida effects.

Conclusion:

The findings demonstrated a considerably greater antibacterial effect
(P<0.05) for the combinations of formononetin + nystatin and chlorhexidine as compared
to nystatin and chlorhexidine alone.
