ABSTRACT
BACKGROUND: Breast cancer awareness is a concept suggesting that awareness of signs and symptoms and early seeking of medical advice may decrease mortality, especially in limited resource settings. METHODS: A modified questionnaire based on the breast cancer awareness measure (BCAM) by Cancer Research UK was translated into Greek and used for the first time. Participants were women residing in a rural border area in Greece. For statistical analysis the χ2 goodness-of-fit and Cramer's V test for categorical comparisons were used and Cronbach's alpha for reliability analysis. RESULTS: In total, 110 women filled out and returned the questionnaire. Respondents appeared to be inappropriately informed regarding the less common warning signs of breast cancer, the most common age of breast cancer occurrence, the national screening program, and the less important risk factors of breast cancer. On the other hand, most women appeared to be confident in recognizing breast changes and seeking medical advice if needed. CONCLUSIONS: The translated modified BCAM tool can be used to evaluate breast cancer awareness in Greek women. Future campaigns developed by policymakers should focus on improving breast cancer awareness, especially in socioeconomically deprived areas.
ABSTRACT
Breast milk is a unique and highly beneficial source of nutrition for infants. It contains a wide range of nutrients that are specifically tailored to meet the specific needs of a growing infant. On the other hand, obesity is a major health issue that affects people around the world. The aim of this study is to investigate the relationship between breastfeeding and child BMI and the role of maternal BMI, which may influence this relationship. This study revealed that a longer duration of exclusive breastfeeding was associated with a decrease in the prevalence of overweight children. Additionally, the research found that children born to overweight or obese women had a higher probability of being overweight or obese themselves. Considering that mothers with a higher pre-pregnancy body weight are more likely to have children with a higher BMI, it is important that they receive information about the advantages of breastfeeding for a minimum of 6 months for both themselves and their children. Additionally, they should be offered ongoing support, to encourage them to start breastfeeding and continue with it beyond this period.
ABSTRACT
Post-traumatic stress disorder symptoms related to work in pediatric departments aremajor public health problems, as they directly affect health organizations, healthcare workers, and, due to the poor quality of care, the patients as well. The post-traumatic symptoms that a healthcare worker may experience are related to intrusion, avoidance, negative changes in cognition and mood, and changes in arousal and reactivity. The aim of the present investigation was to identify risk factors that contribute to the development of PTSD in pediatric healthcare workers, in order to implement necessary workplace measures. A sample of four hundred and forty-five pediatric workers at seven Greek public hospitals consented to participate in the survey. Socio-demographic data and a post-traumatic checklist (5th edition) were used to diagnose post-traumatic stress disorder. According to the results, risk factors for the development of post-traumatic symptoms include medical or nursing errors, threats to a child's life, and incidents of workplace bullying. More specifically, 25.2% of the participants had a provisional PTSD diagnosis, 72.8%of the sample experienced an incident involving a medical or nursing error in their workplace related to the treatment or care of a child, 56% experienced an incident involving a child's death or a threat to a child's life due to a serious illness or injury, and 55.5% experienced an incident of workplace bullying. In addition, it was found that having a university-level education, master's, or PhD, working in a circular shift, being assigned to a department by management rather than the worker, and dissatisfaction with salary were associated with post-traumatic stress disorder. The high rates of PTSD symptoms among participants highlight the need for prevention and management measures to protect and support the mental health of workers in pediatric departments. We propose frequent evaluations of the mental health of employees, more time for rest, incentives for professional development, utilization of their specializations and specialties, support from mental health specialists when symptoms are diagnosed, and the option for employees to change departments if they wish or if they show symptoms of mental trauma.
ABSTRACT
Extensive research into mRNA vaccines for cancer therapy in preclinical and clinical trials has prepared the ground for the quick development of immune-specific mRNA vaccines during the COVID-19 pandemic. Therapeutic cancer vaccines based on mRNA are well tolerated, and are an attractive choice for future cancer immunotherapy. Ideal personalized tumor-dependent mRNA vaccines could stimulate both humoral and cellular immunity by overcoming cancer-induced immune suppression and tumor relapse. The stability, structure, and distribution strategies of mRNA-based vaccines have been improved by technological innovations, and patients with diverse tumor types are now being enrolled in numerous clinical trials investigating mRNA vaccine therapy. Despite the fact that therapeutic mRNA-based cancer vaccines have not yet received clinical approval, early clinical trials with mRNA vaccines as monotherapy and in conjunction with checkpoint inhibitors have shown promising results. In this review, we analyze the most recent clinical developments in mRNA-based cancer vaccines and discuss the optimal platforms for the creation of mRNA vaccines. We also discuss the development of the cancer vaccines' clinical research, paying particular attention to their clinical use and therapeutic efficacy, which could facilitate the design of mRNA-based vaccines in the near future.
ABSTRACT
Objective: The aim of this study was to investigate the relation between cesarean section and postpartum posttraumatic stress disorder as well as the factors that contribute to the development of posttraumatic symptoms in mothers. Materials and methods: A sample of 538 women who gave birth with emergency and elective cesarean section in a University Hospital of Thessaly, Greece, have consented to participate in a two-phase prospective study. A socio-demographic questionnaire, the stressor Criterion A, the Life Events Checklist and the Posttraumatic Checklist of the fifth edition of the Diagnostic and Statistical Manual (DSM-5) were used to diagnose posttraumatic symptoms in Greek postpartum mothers. Results:Out of 538 mothers, 37.2% had an emergency cesarean section and the remaining 62.8% an elective one. Posttraumatic stress was seen in 26 (26%) of women with emergency surgery and three (3%) of those with elective surgery. The present study also found that the inclusion of a neonate to the NICU, complications during pregnancy and delivery, lack of breastfeeding and lack of support from the partner were strongly associated with the development of posttraumatic symptoms. Conclusions:The results of the current study indicate the need to take measures to reduce cesarean section rates and promote vaginal delivery. The high posttraumatic stress rates make it imperative to take additional measures for the mental health of women after cesarean section, especially in those with a traumatic birth experience.
ABSTRACT
Objective:A sizable fraction of young people with active sex lives do not utilize contraceptives and engage in high-risk sexual activity. School-based programs can prevent sexual activity, encourage birth control and reduce high-risk behavior. A survey was conducted to assess the key sources of knowledge on sexual education and document attitudes and methods of contraception used by Greek students, providing valuable information for expanding contraceptive services. Material and methods:A descriptive cross-sectional study was conducted by using an online questionnaire which was distributed to 206 digital student groups on social media platforms from May 20 to June 5, 2021. Results:The majority of participants obtained information about contraception from the Internet and used male condoms to avoid unwanted pregnancy and protect against sexually transmitted diseases (STDs). The present study found that younger ages (18-20 and 21-25) preferred to use the male condom technique in an ephemeral relationship [x² (12) =26.041, Fisher's exact test p= 0.0380.05]. Conclusions:Exploring students' attitudes toward contraceptive usage can provide valuable insights for developing effective strategies to promote safe and responsible sexual behavior among this population.
ABSTRACT
BACKGROUND: The experience of a neonate hospitalised in the Neonatal Intensive Care Unit (NICU) is an understandably traumatic experience for the parents, especially, for the mothers of neonates. This mental distress resulting from preterm birth and/or NICU hospitalisation can be understood as post-traumatic symptomatology, according to the Diagnostic and Statistical Manual-5 version. The aim of this study is to investigate the impact of the admission of a neonate to the NICU (from any reason) on the development of postpartum post-traumatic stress disorder (PTSD) in a sample of women after cesarean sections. MATERIAL AND METHODS: A total of 469 women who gave birth with cesarean section from July 2019 to June 2020 participated in this study, from the original sample of 490 women who consented to participate. Data were obtained from the researcher's socio-demographic questionnaire, the past traumatic Life Events Checklist, the perinatal stressor Criterion A, and the Post-Traumatic Stress Checklist from the Diagnostic and Statistical Manual-5 version. RESULTS: A percentage of 46.64% of sample experienced postpartum PTSD. Factors associated with PTSD were placenta previa type4, abruption, bleeding (ß = .07, p = .049), premature contractions (ß = .08, p = .039), heavy medical history or previous gynecological history and preeclampsia (ß = .08, p = .034), abnormal heart rate, premature rupture of membrane, premature contractions, infections (ß = .14, p = .004), life of child in danger (ß = .12, p = .025), complications involving child (ß = .15, p = .002), complications involving both (child and mother) (ß = .12, p = .011), traumatic cesarean section (ß = .041, p < .001) and prematurity (ß = .12, p = .022). CONCLUSIONS: Additional measures must be taken for mothers of children who have been admitted to the NICU with psychological support interventions and reassessment of their mental state.

INTRODUCTION: Exclusive breastfeeding until six months of life is the ideal way to feed infants. However, there is a significant number of infants who have never breastfed, despite the beneficial properties of breastfeeding. On the other hand, the coronavirus outbreak had significant effects on people's health, both mentally and physically, and has also impacted the breastfeeding process. AIM: The aim of this study was to investigate the implication of COVID-19 on breastfeeding through qualitative data from databases. METHODS: We searched online databases (PubMed, Google Scholar, PsycINFO) for studies published from 2019 to 2023. 'Out of the 2598 papers we found, only 12 were included in the review'. More specifically, from the 1558 papers remaining from the title and abstract evaluation as well as duplicates, a further 1546 papers belonging to our exclusion criteria were removed (all types of reviews, letters to editors, and quantitative articles). RESULTS: Our results covered three subjects: breastfeeding support during the pandemic, effects of social containment measures on breastfeeding, and additional outcomes regarding breastfeeding. Most voices found the effects of the pandemic on breastfeeding beneficial, with reduced professional support and a high degree of support from the environment. Additional negative factors were observed, as well as consequences of the pandemic in women's lives. CONCLUSIONS: COVID-19 was the occasion to understand the power of the supportive environment of the woman, especially the partner, in establishing and maintaining breastfeeding. Therefore, policy makers and health professionals, especially midwives, should implement family-centered breastfeeding strategies that are more supportive of the partner role, providing problem counseling when and where deemed necessary.

Data were obtained from the researcher's socio-demographic questionnaire and the post-traumatic stress checklist (PCL-5) from the Diagnostic and Statistical Manual of Mental Disorders DCM-5 version. RESULTS: In total,11.7% of the sample experienced postpartum PTSD. There is a strong relationship between the inclusion of a neonate to the NICU due to perinatal stress, breathing difficulties, infections, and IUGR with postpartum PTSD (37.7%) in relation to the perinatal stress Criterion A (fear for the life of the neonate), the first criterion of postpartum PTSD. CONCLUSIONS: Additional measures must be taken for mothers of children who have been admitted to the neonatal intensive care unit with psychological support interventions and a reassessment of their mental state.
ABSTRACT
BACKGROUND: The Zika virus outbreak has affected pregnant women and their infants. Affected infants develop microcephaly and other congenital malformations referred to as congenital Zika syndrome. The neurological manifestations of congenital Zika syndrome may result in some feeding disorders, including dysphagia, swallowing dysfunction and choking while feeding. The aim of this study was to assess the prevalence of feeding and breastfeeding difficulties in children with congenital Zika syndrome and to estimate the risk of developing feeding disabilities. METHODS: We searched PubMed, Google Scholar and Scopus for studies published from 2017 to 2021. From the total of 360 papers, reviews, systematic reviews, meta-analyses and publications in languages other than English were excluded. Therefore, the final sample of our study consisted of 11 articles about the feeding/breastfeeding difficulties of infants and children with congenital Zika syndrome. RESULTS: Infants and children with congenital Zika syndrome were likely to suffer from feeding difficulties at various levels, including breastfeeding. Dysphagia problems ranged from 17.9% to 70%, and nutritional and non-nutritive suckling of infants was also affected. CONCLUSIONS: In addition to continuing to investigate the neurodevelopment of affected children, future research should also focus on the severity of factors influencing the degree of dysphagia, as well as the impact of breastfeeding on the child's overall development.

Background: A traumatic birth experience can affect the breastfeeding process and make it ineffective. The aim of this study was to identify the factors associated with breastfeeding ineffectiveness after birth trauma, through the world literature. There are several factors responsible for a traumatic birth experience, such as obstetric violence, postpartum complications and complications induced by doctors, invasive vaginal deliveries, emergency caesarean sections, admission of a neonate to the Neonatal Intensive Unit, past traumatic life events and mental health problems. Objective: The aim of this study was to identify the factors associated with breastfeeding ineffectiveness after birth trauma, through the world literature. Methods: An extended search was conducted to identify relevant for breastfeeding and traumatic birth experiences manuscripts for this study. Databases including PubMed, PsycINFO and Google Scholar. The search was limited to articles published in English the last decade. Results: Factors that contribute to the ineffectiveness of breastfeeding after a traumatic birth are hormonal, medication, insufficient support from the partner, reliving the traumatic birth experience, past traumatic experiences in the woman's life and her mental state. Conclusion: The mental trauma during childbirth is complex and multifactorial. Therefore, it is necessary to take measures on the one hand to prevent mental trauma during childbirth and on the other hand to make interventions to deal with the consequences of the trauma on the mental health of the mother and on breastfeeding which is directly affected.
ABSTRACT
Following its therapeutic effect in hematological metastasis, chimeric antigen receptor (CAR) T cell therapy has gained a great deal of attention during the last years. However, the effectiveness of this treatment has been hampered by a number of challenges, including significant toxicities, difficult access to tumor locations, inadequate therapeutic persistence, and manufacturing problems. Developing novel techniques to produce effective CARs, administer them, and monitor their anti-tumor activity in CAR-T cell treatment is undoubtedly necessary. Exploiting the advantages of nanotechnology may possibly be a useful strategy to increase the efficacy of CAR-T cell treatment. This study outlines the current drawbacks of CAR-T immunotherapy and identifies promising developments and significant benefits of using nanotechnology in order to introduce CAR transgene motifs into primary T cells, promote T cell expansion, enhance T cell trafficking, promote intrinsic T cell activity and rewire the immunosuppressive cellular and vascular microenvironments. Therefore, the development of powerful CART cells can be made possible with genetic and functional alterations supported by nanotechnology. In this review, we discuss the innovative and possible uses of nanotechnology for clinical translation, including the delivery, engineering, execution, and modulation of immune functions to enhance and optimize the anti-tumor efficacy of CAR-T cell treatment.
ABSTRACT
A significant factor in the antitumor immune response is the increased metabolic reprogramming of immunological and malignant cells. Increasing data points to the fact that cancer metabolism affects not just cancer signaling, which is essential for maintaining carcinogenesis and survival, but also the expression of immune cells and immune-related factors such as lactate, PGE2, arginine, IDO, which regulate the antitumor immune signaling mechanism. In reality, this energetic interaction between the immune system and the tumor results in metabolic competition in the tumor ecosystem, limiting the amount of nutrients available and causing microenvironmental acidosis, which impairs the ability of immune cells to operate. More intriguingly, different types of immune cells use metabolic reprogramming to keep the body and self in a state of homeostasis. The process of immune cell proliferation, differentiation, and performance of effector functions, which is crucial to the immune response, are currently being linked to metabolic reprogramming. Here, we cover the regulation of the antitumor immune response by metabolic reprogramming in cancer cells and immune cells as well as potential strategies for metabolic pathway targeting in the context of anticancer immunotherapy. We also discuss prospective immunotherapy-metabolic intervention combinations that might be utilized to maximize the effectiveness of current immunotherapy regimes.

Antiphospholipid syndrome (APS) refers to a clinical autoimmune syndrome characterized by arterial or venous thrombosis and pregnancy morbidities, such as fetal loss after the 10th week of gestation, recurrent miscarriages, or intrauterine growth restriction. This study describes a case of preeclampsia in a 37-year-old primiparous woman in the 30th week of pregnancy with a lack of prior thrombotic history. The birth of a dead neonate and the findings of placenta thrombosis raised the suspicion of APS, which was confirmed by the finding of antibodies. A description of the treatment, which is still under investigation, follows. In our case, tissue sections were stained followed by observation. Various placental changes were detected with the presence of placental intravascular thrombi. The most important finding of this case study is the presence of severe preeclampsia in the setting of APS, with no previous medical history. In conclusion, antiphospholipid syndrome can be directly related to preeclampsia during pregnancy, leading to complications that may be preventable if immediate medical intervention is available.
ABSTRACT
The appearance of chemoresistance in cancer is a major issue. The main barriers to conventional tumor chemotherapy are undesirable toxic effects and multidrug resistance. Cancer nanotherapeutics were developed to get around the drawbacks of conventional chemotherapy. Through clinical evaluation of thoughtfully developed nano delivery systems, cancer nanotherapeutics have recently offered unmatched potential to comprehend and combat drug resistance and toxicity. In different design approaches, including passive targeting, active targeting, nanomedicine, and multimodal nanomedicine combination therapy, were successful in treating cancer in this situation. Even though cancer nanotherapy has achieved considerable technological development, tumor biology complexity and heterogeneity and a lack of full knowledge of nano-bio interactions remain important hurdles to future clinical translation and commercialization. The recent developments and advancements in cancer nanotherapeutics utilizing a wide variety of nanomaterial-based platforms to overcome cancer treatment resistance are covered in this article. Additionally, an evaluation of different nanotherapeutics-based approaches to cancer treatment, such as tumor microenvironment targeted techniques, sophisticated delivery methods for the precise targeting of cancer stem cells, as well as an update on clinical studies are discussed. Lastly, the potential for cancer nanotherapeutics to overcome tumor relapse and the therapeutic effects and targeted efficacies of modern nanosystems are analyzed.
ABSTRACT
The tumor microenvironment plays a key role in progression of tumorigenesis, tumor progression, and metastasis. Accumulating data reveal that dendritic cells (DCs) appear to play a key role in the development and progression of metastatic neoplasia by driving immune system dysfunction and establishing immunosuppression, which is vital for tumor evasion of host immune response. Consequently, in this review, we will discuss the function of tumor-infiltrating DCs in immune cell signaling pathways that lead to treatment resistance, tumor recurrence, and immunosuppression. We will also review DC metabolism, differentiation, and plasticity, which are essential for metastasis and the development of lung tumors. Furthermore, we will take into account the interaction between myeloid cells and DCs in tumor-related immunosuppression. We will specifically look into the molecular immune-related mechanisms in the tumor microenvironment that result in reduced drug sensitivity and tumor relapse, as well as methods for combating drug resistance and focusing on immunosuppressive tumor networks. DCs play a crucial role in modulating the immune response. Especially, as cancer progresses, DCs may switch from playing an immunostimulatory to an inhibitory role. This article's main emphasis is on tumor-infiltrating DCs. We address how they affect tumor growth and expansion, and we highlight innovative approaches for therapeutic modulation of these immunosuppressive DCs which is necessary for future personalized therapeutic approaches.

BACKGROUND: Breastfeeding is very important for the proper nutrition and growth of the child, as well as, the health of the mother. To start breastfeeding, the neonate must have extensive oral capacities for sucking functions but, premature neonates may not have the muscle strength needed to suck successfully. However, the non-nutritive sucking achieved by using a pacifier, has been identified by previous research as a factor associated with shorter duration and exclusivity of breastfeeding. This study aims to perform a systematic review to investigate the relationship between pacifier use in preterm neonates and breastfeeding in infancy. METHODS: We included prospective studies, as well as randomized controlled studies that evaluated the association between pacifier use by preterm neonates and of breastfeeding in infancy. Ten research articles from PubMed/Medline, Google Scholar and Crossref were included in the review from a total of 1455 articles. The results differ depending on the type of study.Most prospective studies have shown a negative correlation between pacifier use and breastfeeding, while the randomized controlled studies found a positive correlation. CONCLUSIONS: Pacifier use in preterm infants helps transition from tube to oral feeding, breastfeeding, faster weight gain and earlier discharge from the NICU. However, the relationship between pacifiers and breastfeeding is more complicated, as it appears to be influenced by additional risk factors.
ABSTRACT
BACKGROUND: Although childbirth is considered a natural process, a high percentage of postpartum women consider it traumatic. Any previous traumatic event in a woman's life can be revived through a traumatic birth experience, especially after a complicated vaginal delivery or cesarean delivery. The purpose of this study was to clarify the relationship between previous traumatic life events and posttraumatic stress disorder (PTSD) in postpartum women after cesarean section and which specific events exerted the greatest influence. METHODS: A sample of 469 women who had undergone cesarean sections at a Greek university hospital consented to participate in this prospective study. Data from a medical/demographic questionnaire, life events checklist, perinatal stressor criterion A, and posttraumatic stress checklist were used to evaluate past traumatic life events and diagnose postpartum posttraumatic stress. RESULTS: Out of 469 women, 25.97% had PTSD and 11.5% a PTSD profile, while 2.7% had PTSD and 2.7% a PTSD profile. Also, it appeared that only specific direct exposure to a traumatic event and/or witnessing one were predictors of postpartum PTSD. CONCLUSIONS: This survey identified specific traumatic life events, psychiatric history, stressor perinatal criterion A, preterm birth, and emergency cesarean section as risk factors for the development of PTSD or a PTSD profile in women after cesarean delivery.
ABSTRACT
The tumor microenvironment plays a key role in the progression of lung tumorigenesis, progression, and metastasis. Recent data reveal that disseminated tumor cells (DTCs) appear to play a key role in the development and progression of lung neoplasiaby driving immune system dysfunction and established immunosuppression, which is vital for evading the host immune response. As a consequence, in this review we will discuss the role and function of DTCs in immune cell signaling routes which trigger drug resistance and immunosuppression. We will also discuss the metabolic biology of DTCs, their dormancy, and their plasticity, which are critical for metastasis and drive lung tumor progression. Furthermore, we will consider the crosstalk between DTCs and myeloid cells in tumor-related immunosuppression. Specifically, we will investigate the molecular immune-related mechanisms in the tumor microenvironment that lead to decreased drug sensitivity and tumor relapse, along with strategies for reversing drug resistance and targeting immunosuppressive tumor networks. Deciphering these molecular mechanisms is essential for preclinical and clinical investigations in order to enhance therapeutic efficacy. Furthermore, a better understanding of these immune cell signaling pathways that drive immune surveillance, immune-driven inflammation, and tumor-related immunosuppression is necessary for future personalized therapeutic approaches.
