Background: Empathy cultivates deeper interpersonal relationships; however, frequent exposure can trigger the risk of burnout. This study aims to predict empathy, burnout, and syndrome among nursing staff in a university hospital in Central Greece.

Material and methods: This is a synchronic study on the nursing staff of the university general hospital in central Greece. The sample consisted of 210 nurses who took part in the study by completing a questionnaire that included demographic and social characteristics, the "Copenhagen Burnout Inventory" and the "Composite Empathy Scale." The Pearson correlation coefficient (r) and linear regression analysis with a statistical significance of 0.05 were used for the statistical analysis. Univariate and multiple logistic regression analyses were used to determine the potential predictive factors associated with burnout and empathy.

Results: The prevalence of burnout and empathy among nursing staff was 62.5%. A significant positive correlation between empathy with burnout was found in almost all dimensions. For burnout subscales, "Personal Burnout" was found to be at 44.1%, Operational Burnout "at 62.5%, and in" Burn related to patients "the average was 58.3%. A higher level of burnout is associated with" Workplace Burnout "for nurses on shift work. There was a significant negative correlation between "Cognitive Personal Empathy" and the "Personal Burnout." Also, 92.9% of the nursing staff reported suffering from a disease.

Conclusion: The nurses in the university hospital are "aged staff" with health problems, high levels of empathy, and burnout.

背景:共情培养更深层次的人际关系;然而,频繁接触会引发倦怠的风险。本研究旨在预测希腊中部一所大学医院护理人员的共情、倦怠和综合症。材料与方法:对希腊中部一所大学综合医院的护理人员进行同期性研究。样本由210名护士组成,他们完成了一份调查问卷,包括人口统计和社会特征,“哥本哈根倦怠量表”和“复合同理心量表”。采用Pearson相关系数(r)和具有统计学意义0.05的线性回归分析进行统计分析。采用单因素和多元逻辑回归分析确定倦怠和共情的潜在预测因素。结果:护理人员倦怠和共情的患病率为62.5%。共情与倦怠几乎在所有维度上都存在显著的正相关。在倦怠子量表中,“个人倦怠”的平均比例为44.1%,“工作倦怠”的平均比例为62.5%,“与患者相关的倦怠”的平均比例为58.3%。在轮班工作的护士中,较高水平的倦怠与“工作场所倦怠”有关。“认知个人共情”与“个人倦怠”呈显著负相关。此外,92.9%的护理人员报告患有某种疾病。结论:大学医院护士是健康问题、共情水平高、职业倦怠的“老年员工”。

Introduction: Mental health nursing can be highly rewarding but at the same time overwhelmingly stressful or even traumatizing. Spirituality constitutes a central element of mental health nurses' resilience while personal trauma may be activated during exposure to beneficiaries' trauma.

Aim: The aim of this study is to examine the impact of sociodemographic and work-related characteristics, spirituality, and history of trauma on compassion fatigue (CF) and compassion satisfaction among psychiatric nurses in Greece.

Methods: A cross-sectional survey study with a total of 91 mental health nurses selected by convenience sampling and required to complete the Professional Quality of Life Scale (ProQOL-V), the FACIT-Spiritual Well-Being Scale-12 non-illness scale, and the Traumatic Life Events Questionnaire (TLEQ).

Results: More than a quarter (25.3%) of participants reported high compassion fatigue risk, while 76% expressed high to moderate potential for compassion satisfaction. Secondary traumatic stress (STS) as expected was found to correlate positively with traumatic life events and negatively with the spirituality dimension of meaning. Spiritual well-being, good physical health, high levels of cooperation, respect for teamwork and positive work climate were positively related to higher levels of compassion satisfaction.

Conclusion: The findings of this study shed light on the significant prevalence of compassion fatigue and personal trauma history among nursing staff, highlighting the need for targeted interventions to improve the mental health of front-line health care nurses. Mental health care organizations must recognize the importance of fostering compassionate work environments that prioritize mental health professionals' spiritual and psychological well-being.

心理健康护理可以获得很高的回报,但同时也会带来巨大的压力,甚至是创伤。精神是心理健康护士恢复力的核心要素,而个人创伤可能在接触受益者的创伤时被激活。目的:本研究旨在探讨希腊精神科护士的社会人口学特征、工作特征、精神状态和创伤史对同情疲劳(CF)和同情满意度的影响。方法:采用横断面调查法,随机抽取91名心理健康护士,分别填写职业生活质量量表(ProQOL-V)、facit -精神健康量表-12非疾病量表和创伤性生活事件问卷(TLEQ)。结果:超过四分之一(25.3%)的参与者报告了高同情疲劳风险,而76%的参与者表达了高到中等的同情满意度潜力。继发性创伤应激与创伤性生活事件呈正相关,与意义的精神性维度负相关。精神健康、良好的身体健康、高水平的合作、对团队合作的尊重和积极的工作氛围与高水平的同情满意度呈正相关。结论:本研究结果揭示了护理人员同情疲劳和个人创伤史的显著患病率,强调需要有针对性的干预措施来改善一线医护人员的心理健康。精神卫生保健组织必须认识到培养富有同情心的工作环境的重要性,优先考虑精神卫生专业人员的精神和心理健康。

Insects, like most animals, have intimate interactions with microorganisms that can influence the insect host's lipid metabolism. In this chapter, we describe what is known so far about the role prokaryotic microorganisms play in insect lipid metabolism. We start exploring microbe-insect lipid interactions focusing on endosymbionts, and more specifically the gut microbiota that has been predominantly studied in Drosophila melanogaster. We then move on to an overview of the work done on the common and well-studied endosymbiont Wolbachia pipientis, also in interaction with other microbes. Taking a slightly different angle, we then look at the effect of human pathogens, including dengue and other viruses, on the lipids of mosquito vectors. We extend the work on human pathogens and include interactions with the endosymbiont Wolbachia that was identified as a natural tool to reduce the spread of mosquito-borne diseases. Research on lipid metabolism of plant disease vectors is up and coming and we end this chapter by highlighting current knowledge in that field.

昆虫,像大多数动物一样,与微生物有密切的相互作用,可以影响昆虫宿主的脂质代谢。在本章中,我们描述了迄今为止已知的原核微生物在昆虫脂质代谢中的作用。我们开始探索微生物-昆虫脂质相互作用,重点关注内共生菌,更具体地说,是在果蝇中主要研究的肠道微生物群。然后我们继续对常见的和研究得很好的内共生沃尔巴克氏体(Wolbachia pipientis)进行概述,也与其他微生物相互作用。然后,我们从一个稍微不同的角度来看,包括登革热和其他病毒在内的人类病原体对蚊子载体脂质的影响。我们扩展了人类病原体的工作,包括与内共生沃尔巴克氏体的相互作用,沃尔巴克氏体被确定为减少蚊媒疾病传播的天然工具。植物病媒脂质代谢的研究正在兴起,我们在本章的最后重点介绍了该领域的最新知识。

Lipids are essential in insects and play pleiotropic roles in energy storage, serving as a fuel for energy-driven processes such as reproduction, growth, development, locomotion, flight, starvation response, and diapause induction, maintenance, and termination. Lipids also play fundamental roles in signal transduction, hormone synthesis, forming components of the cell membrane, and thus are essential for maintenance of normal life functions. In insects, the neuroendocrine system serves as a master regulator of most life activities, including growth and development. It is thus important to pay particular attention to the regulation of lipid metabolism through the endocrine system, especially when considering the involvement of peptide hormones in the processes of lipogenesis and lipolysis. In insects, there are several lipogenic and lipolytic hormones that are involved in lipid metabolism such as insulin-like peptides (ILPs), adipokinetic hormone (AKH), 20-hydroxyecdysone (20-HE), juvenile hormone (JH), and serotonin. Other neuropeptides such as diapause hormone-pheromone biosynthesis activating neuropeptide (DH-PBAN), CCHamide-2, short neuropeptideF, and the cytokines Unpaired 1 and 2 may play a role in inducing lipogenesis. On the other hand, neuropeptides such as neuropeptide F, allatostatin-A, corazonin, leukokinin, tachykinins, limostatins, and insulin-like growth factor (ILP6) stimulate lipolysis. This chapter briefly discusses the current knowledge of the endocrine regulation of lipid metabolism in insects that could be utilized to reveal differences between insects and mammalian lipid metabolism which may help understand human diseases associated with dysregulation of lipid metabolism. Physiological similarities of insects to mammals make them valuable model systems for studying human diseases characterized by disrupted lipid metabolism, including conditions like diabetes, obesity, arteriosclerosis, and various metabolic syndromes.

脂类在昆虫体内是必不可少的,在能量储存中发挥着多效性作用,作为能量驱动过程的燃料,如繁殖、生长、发育、运动、飞行、饥饿反应、滞育诱导、维持和终止。脂质还在信号转导、激素合成、形成细胞膜成分等方面发挥着重要作用,因此对维持正常的生命功能至关重要。在昆虫中,神经内分泌系统是大多数生命活动的主要调节器,包括生长和发育。因此,特别关注通过内分泌系统调节脂质代谢是很重要的,特别是当考虑到肽激素在脂肪生成和脂肪分解过程中的参与时。昆虫体内有多种脂质代谢激素,如胰岛素样肽(ILPs)、脂肪动力学激素(AKH)、20-羟基蜕皮激素(20-HE)、幼年激素(JH)和血清素。其他神经肽如滞育激素-信息素生物合成激活神经肽(DH-PBAN)、CCHamide-2、短神经肽def和细胞因子Unpaired 1和2可能在诱导脂肪生成中发挥作用。另一方面,神经肽如神经肽F、allatostatin-A、corazonin、白细胞分裂素、速激肽、limostatins和胰岛素样生长因子(ILP6)刺激脂肪分解。本章简要讨论了目前关于昆虫脂质代谢的内分泌调节的知识,可以用来揭示昆虫和哺乳动物脂质代谢的差异,这可能有助于了解与脂质代谢失调相关的人类疾病。昆虫与哺乳动物的生理相似性使它们成为研究以脂质代谢紊乱为特征的人类疾病的有价值的模型系统,包括糖尿病、肥胖、动脉硬化和各种代谢综合征等疾病。

Hashimoto's disease or Hashimoto's thyroiditis is an autoimmune disorder of the thyroid gland. The pathophysiology of the disorder is characterized by an increased volume of the thyroid gland, infiltration of the parenchyma by lymphocytes, and the presence of antibodies specific for thyroid antigens. The diagnosis of Hashimoto thyroiditis is based on the presence of clinical symptoms, anti-thyroid antibodies, and certain histologic features. The present study aimed to collect biomarkers and create a web-based application for detecting the disease through machine learning. The web application was created using Python and Random Forest algorithm was selected to train the existing dataset. Taking advantage of machine learning algorithms, the application provides users with a practical means for predicting immortality based on their blood tests. Although there are limitations that need to be addressed, representing a valuable tool for early diagnosis and management of the disease is required.

Neurodegenerative diseases such as Alzheimer's, Parkinson's, ALS, and Huntington's disease pose a growing global health challenge due to their prevalence in aging populations and their devastating impact on cognitive and motor functions. Current treatments focus on symptom management, with no options available to reverse neuronal damage. Emerging evidence highlights the potential role of extra virgin olive oil (EVOO) polyphenols in neuroprotection, particularly in the context of the Mediterranean diet, which is associated with lower rates of neurodegenerative disorders. EVOO's rich polyphenolic compounds, including hydroxytyrosol, oleuropein, tyrosol, and oleocanthal, exhibit potent antioxidant, anti-inflammatory, and neuroprotective properties. These bioactive molecules have shown potential in modulating disease-specific pathways, such as reducing oxidative stress, inhibiting abnormal protein aggregation, and regulating neuroinflammation. This paper explores the therapeutic potential of olive oil polyphenols for neurodegenerative diseases, detailing their mechanisms of action across different conditions. Our findings suggest that incorporating EVOO into dietary and medical interventions could serve as a promising strategy for mitigating neurodegenerative disease progression and enhancing cognitive health.

神经退行性疾病,如阿尔茨海默氏症、帕金森氏症、肌萎缩侧索硬化症和亨廷顿氏病,由于其在老年人群中的流行以及对认知和运动功能的破坏性影响,构成了日益严重的全球健康挑战。目前的治疗侧重于症状管理,没有可用于逆转神经元损伤的选择。新出现的证据强调了特级初榨橄榄油(EVOO)多酚在神经保护方面的潜在作用,特别是在地中海饮食的背景下,这与神经退行性疾病的发病率较低有关。EVOO富含多酚类化合物,包括羟基酪醇、橄榄苦苷、酪醇和油籽酚,具有强大的抗氧化、抗炎和神经保护特性。这些生物活性分子已显示出在调节疾病特异性途径方面的潜力,如减少氧化应激、抑制异常蛋白质聚集和调节神经炎症。本文探讨了橄榄油多酚对神经退行性疾病的治疗潜力,详细介绍了它们在不同条件下的作用机制。我们的研究结果表明,将EVOO纳入饮食和医疗干预可能是缓解神经退行性疾病进展和增强认知健康的一种有希望的策略。

Aim: To explore the psychological impact on children and adolescents after the withdrawal of COVID-19 restrictions.

Methods and materials: This study was a cross-sectional study with a convenience sample. The sample consisted of 100 children and adolescents, and it was conducted in the outpatient department of the pediatric population of the Regional Unit of Trikala. The scale used in the present study explores post-pandemic coping strategies upon life returning to normal for children and teenagers, "PPCSRN-CT." The data were analyzed with the SPSS-12 statistical package, and multiple linear regression was performed. The level of statistical significance was set at p < 0.05.

Results: In the study, nearly 60% of the participants were girls, and over 80% of the children and adolescents lived in urban areas in Trikala Prefecture. Half of them (50%) were 12 years old or older. The statistical analysis found that children and adolescents worry significantly more about the health of their loved ones when they are alone and don't have anyone to share their concerns with (p = 0.008). Furthermore, children and adolescents who lived with both parents believe that their parents have become less strict with them after the withdrawal of restrictions due to the pandemic (p = 0.001). Additionally, children and adolescents living with both parents believe that their parents care for them more after the withdrawal of restrictions due to the COVID-19 pandemic (p = 0.013). The study also revealed that the desire of children and teenagers to learn more about COVID-19 is positively affected by whether someone close to them has been sick with SARS-CoV-2 (p = 0.009). Furthermore, children and adolescents who want to learn more about the COVID-19 pandemic and whose parents are less strict with them expect their lives to return to normal immediately after the removal of restrictions due to the COVID-19 pandemic (p = 0.016 and p = 0.006, respectively). Finally, the study found that children and adolescents' belief that they will move on in life together with friends is positively influenced by whether they are less emotionally burdened (p = 0.024) and by whether they are more positive about their daily life (p < 0.001).

Conclusions: It is important to evaluate the perceptions of children and adolescents post-pandemic in order to implement interventions to empower this group.

背景:大流行期间为保护公众健康而采取的措施对儿童和青少年的心理、社会和身体健康产生了重大影响。限制性措施影响了他们的发展、行为、学校生活、家庭和友谊。目的:探讨解除COVID-19限制后对儿童和青少年的心理影响。方法和材料:本研究采用方便样本的横断面研究。样本包括100名儿童和青少年,是在特里卡拉地区儿科门诊进行的。本研究中使用的量表探讨了儿童和青少年在生活恢复正常后的大流行应对策略,“PPCSRN-CT”。采用SPSS-12统计软件包对数据进行分析,并进行多元线性回归。结果:在研究中,近60%的参与者是女孩,超过80%的儿童和青少年生活在特里卡拉省的城市地区。其中一半(50%)年龄在12岁或以上。统计分析发现,当儿童和青少年独自一人,没有人可以分享他们的担忧时,他们对亲人的健康担忧明显增加(p = 0.008)。此外,与父母双方生活在一起的儿童和青少年认为,在大流行取消限制后,父母对他们的要求降低了(p = 0.001)。此外,与父母双方共同生活的儿童和青少年认为,在新冠肺炎大流行取消限制后,父母更关心他们(p = 0.013)。该研究还显示,儿童和青少年更多地了解COVID-19的愿望与他们身边的人是否患有SARS-CoV-2呈正相关(p = 0.009)。此外,希望更多地了解COVID-19大流行的儿童和青少年以及父母对他们的要求不那么严格的儿童和青少年期望在因COVID-19大流行而取消限制后立即恢复正常生活(p = 0.016和p = 0.006)。最后,研究发现,儿童和青少年认为他们将与朋友一起生活的信念受到他们是否减轻情感负担(p = 0.024)和他们是否对日常生活更加积极的积极影响(p结论:重要的是要评估大流行后儿童和青少年的看法,以便实施干预措施,赋予这一群体权力。

Introduction: Healthcare professionals working with individuals who have experienced trauma are at risk of experiencing secondary trauma.

Purpose: To explore the perspectives and experiences of addiction nurses working in substitution treatment units and harm reduction services regarding the physical or psychological trauma of individuals coping with the dual burden of addiction and trauma.

Methodology: A mixed-method study (quantitative and qualitative) involving 111 addiction nurses. For the collection of quantitative data, the Greek version of the Professional Quality of Life Scale was used, which assesses compassion satisfaction, professional burnout, and secondary traumatic stress, as well as a questionnaire capturing demographic, individual, and professional characteristics. Eight nurses participated in semistructured interviews.

Results: The majority of participants reported (96.4%) moderate to high levels of compassion satisfaction while more than half (54.4%) of the participants reported low levels of professional burnout, and about half (49.5%) reported low levels of secondary traumatic stress. Considering Stamm's interpretation of the triad of high compassion satisfaction, moderate-to-low professional burnout, and secondary traumatic stress, the results of this study fall into the positive results category. Good physical health, participants' readiness to care for individuals with trauma, high levels of cooperation, respect for teamwork, positive work climate, and seamless colleague support were positively related to higher levels of compassion satisfaction.

Conclusions: Recognizing, reflecting on, and understanding trauma processes protected participants from mirroring the helplessness, frustration, and feelings of incompetence they encountered on the trauma responses of the individuals and families they cared for.

简介:医疗保健专业人员与个人谁经历过创伤是在经历二次创伤的风险。目的:探讨在替代治疗单位和减少伤害服务机构工作的成瘾护士对个体应对成瘾和创伤双重负担的生理或心理创伤的看法和经验。方法:采用混合方法(定量和定性)对111名成瘾护士进行研究。为了收集定量数据,我们使用了希腊版的职业生活质量量表(Professional Quality of Life Scale),该量表评估了同情满意度、职业倦怠和继发性创伤压力,以及一份捕捉人口统计学、个人和职业特征的问卷。8名护士参加了半结构化访谈。结果:大多数参与者(96.4%)表现出中高水平的同情满意度,超过一半(54.4%)的参与者表现出低水平的职业倦怠,约一半(49.5%)的参与者表现出低水平的继发性创伤应激。考虑到Stamm对高同情满意度、中低职业倦怠和继发性创伤应激三位一体的解释,本研究的结果属于积极的结果范畴。良好的身体健康、参与者愿意照顾创伤患者、高水平的合作、对团队的尊重、积极的工作氛围和无缝的同事支持与更高水平的同情满意度呈正相关。结论:认识、反思和理解创伤过程可以保护参与者避免将他们所遇到的无助、沮丧和无能感反映到他们所照顾的个人和家庭的创伤反应中。

Childhood and adolescent obesity is a growing health concern with complex multifactorial origins, encompassing genetic, environmental, physiological, and psychosocial factors. In Greece, the prevalence of childhood obesity is among the highest in Europe, indicating an urgent need to understand its underlying mechanisms. Herein, we explore the genetic basis of obesity, focusing on both monogenic and polygenic factors, and how early life stressors contribute to obesity's onset and progression. Genetic predispositions, such as mutations in leptin-melanocortin pathways, and the role of epigenetic modifications influenced by environmental factors, are examined to understand obesity's complexity. Moreover, stress-related hormonal dysregulation impacts metabolic pathways, exacerbating weight gain and obesity-related complications. Through advanced algorithms like neural networks, decision trees, and clustering techniques, ML/AI approaches have demonstrated high accuracy in predicting obesity, identifying genetic markers, and analyzing interactions between genetic and lifestyle factors. These technologies hold promise for early detection, personalized interventions, and the development of targeted prevention strategies. The integration of ML/AI with genomic, epigenomic, and clinical data offers a comprehensive understanding of childhood obesity, paving the way for more effective management and treatment. This study contributes to a deeper understanding of the genetic and environmental factors in childhood obesity and highlights the potential of AI-driven approaches in addressing this critical public health challenge.

儿童和青少年肥胖是一个日益严重的健康问题,具有复杂的多因素起源,包括遗传、环境、生理和社会心理因素。在希腊,儿童肥胖的患病率是欧洲最高的,这表明迫切需要了解其潜在机制。在此,我们探讨肥胖的遗传基础,重点关注单基因和多基因因素,以及早期生活压力因素如何影响肥胖的发生和发展。遗传易感性,如瘦素-黑素皮质素通路的突变,以及受环境因素影响的表观遗传修饰的作用,被检查以了解肥胖的复杂性。此外,与压力相关的激素失调会影响代谢途径,加剧体重增加和肥胖相关并发症。通过神经网络、决策树和聚类技术等先进算法,ML/AI方法在预测肥胖、识别遗传标记以及分析遗传和生活方式因素之间的相互作用方面表现出了很高的准确性。这些技术有望用于早期发现、个性化干预和制定有针对性的预防战略。ML/AI与基因组、表观基因组和临床数据的整合提供了对儿童肥胖的全面了解,为更有效的管理和治疗铺平了道路。这项研究有助于更深入地了解儿童肥胖的遗传和环境因素,并突出了人工智能驱动的方法在应对这一重大公共卫生挑战方面的潜力。

Temperature directly shapes insect physiology and has a preponderant effect on life history traits. Winter conditions in temperate and polar regions are especially challenging for insects. Extremely low temperatures can indeed compromise insect survival by promoting freezing of body fluids, but mild cold temperatures above 0 °C (i.e., chilling) can also lead to complex and severe physiological dysregulations. Among physiological damages due to freezing and chilling, insect lipids are one of the primary targets. As low temperatures tend to rigidify phospholipid bilayers, membrane functions are compromised in the cold. Lipid rigidification due to cold also decreases the accessibility of fat stores for metabolic enzymes, and therefore their availability for basal metabolism. These deleterious effects, combined with low food availability in winter, result in substantial nutritional challenges for overwintering insects. Consequently, lipid modifications such as homeoviscous adaptation of cell membranes, fluidity maintenance of fat reserves, cuticular lipid accumulation, and production of antifreeze glycolipids are essential components of the physiological response to cold stress. The aim of the present chapter is to present the physiological challenges caused by low temperatures, the lipid modifications linked with cold tolerance in insects, and the molecular regulation of lipid metabolism during cold exposure.

温度直接影响昆虫的生理,并对生活史性状有显著影响。温带和极地地区的冬季条件对昆虫来说尤其具有挑战性。极低的温度确实会促进体液冻结,从而损害昆虫的生存,但0°C以上的温和低温(即寒冷)也会导致复杂而严重的生理失调。在冻害和低温引起的生理损伤中,昆虫脂质是主要目标之一。由于低温会使磷脂双分子层变硬,膜的功能在寒冷中受到损害。由于寒冷导致的脂质硬化也降低了代谢酶对脂肪储存的可及性,从而降低了它们对基础代谢的可用性。这些有害影响,加上冬季食物供应不足,给越冬昆虫带来了严重的营养挑战。因此,脂质修饰,如细胞膜的黏性适应、脂肪储备的流动性维持、角质层脂质积累和抗冻糖脂的产生是对冷应激生理反应的重要组成部分。本章的目的是介绍低温引起的生理挑战,昆虫的脂质修饰与耐寒性有关,以及冷暴露过程中脂质代谢的分子调控。
