The Relationship Between Tumor Budding and Patient's Survival in Breast Cancer.

Introduction: Breast cancer is a severe life-threatening condition in which many women are involved yearly. One factor that has recently been noticed and investigated as a diagnostic predictor of this type of cancer is the number of tumor buds and the relation of this factor with a patient's survival rate. Materials and methods: This study includes 150 female patients over 18 years old with a mean age of 53.99 ± 12.56 years old with breast cancer, which was diagnosed at various medical centers, including Rouhani Hospital itself, and referred to Rouhani Hospital Medical Center, Babol, Iran. The number of intratumoral and peritumoral buds in patients' microscopic slides were archived and evaluated along with tumor microenvironment on hematoxylin and eosin (H&E) slides and compared to other clinicopathological findings. This article precisely investigated the relationship between the number of intratumoral and peritumoral buds with patients' 5-year survival rate. Also, the relationship between age, tumor stage, grade, size, the number of lymph nodes involved, and the presence of metastasis with the number of intratumoral and peritumoral buds was studied. Results and discussion: The result showed a significant statistical association between the number of intratumoral and peritumoral buds with tumor size, tumor stage, presence of metastasis, the number of lymph nodes involved, and 5-year survival rate. On the other hand, there is not a significant statistical association between the number of intratumoral and peritumoral buds with age and tumor grade. Conclusion: Our investigation revealed a significant statistical relationship between the number of tumor buds and patients' survival rate. So, this factor should be considered significant to help those patients increase their survival ratio.

Social learning-based health literacy promotion on the self efficacy and social anxiety of adolescents with type 1 diabetes.

BACKGROUND AND OBJECTIVE: Type 1 diabetes mellitus one of the biggest health concerns around the world, is difficult to manage during adolescence. Among the non-medical methods of controlling this disease is empowerment through self-efficacy. Poor self-efficacy leads to social anxiety and ultimately deficiencies in diabetes. There is also a correlation among health literacy, self-efficacy, and social anxiety. Thus, the present study aimed to evaluate the impact of a literacy promotion training program based on social learning theory on the self-efficacy and social anxiety of adolescents with T1DM. METHODS: The current research is a semi-experimental type that was carried out with the cooperation of 66 adolescents aged 15-18 years with type 1 diabetes in Iran (Tehran, 2022). It has control and intervention groups. The endocrinology and diabetes clinics of the intervention and control groups were randomly selected in a multi-stage manner (endocrine and diabetes clinic of children's medical center hospital for the control group and endocrine and diabetes clinic of Mofid hospital for the intervention group) and the participants were selected by Simple Random Sampling method (draw). The training program designed based on Bandura's social learning theory was used to teach adolescents during seven consecutive sessions of 30-45 min during one week. Questionnaires were completed before and one month after the intervention. Data were analysed in SPSS-25 software. FINDINGS: The intervention for adolescents with T1DM in intervention group compared to the control group had a significant effect on improve health literacy (P<0.001), self-efficacy (P<0.001), and social anxiety (P<0.05). CONCLUSIONS: The results can also be used to improve the capabilities of adolescents with T1DM, reduce and prevent disease complications, and develop operational-educational programs in the centers from which these adolescents receive various services.

Association between quantitative morphological traits and RAPD molecular markers in pomegranate (Punica granatum L.).

Pomegranate (Punica granatum L.) is very important in terms of horticulture and food around the world. The present research aimed to identify the random amplified polymorphic DNA (RAPD) markers associated with morphological traits in pomegranate genotypes. Significant differences were observed among the studied genotypes based on the recorded traits. The 18 RAPD primers produced a total of 154 polymorphic fragments among genotypes. Using multiple regression analysis between each of the morphological traits and 154 RAPD polymorphic bands, RAPD markers associated with each of the morphological traits were identified. In total, 11 markers showed significant correlations with fruit weight, 9 markers with 100-aril weight, 11 markers with anthocyanin, and 8 markers with total soluble solids. Some markers were associated with more than one morphological trait, showing that the association of a marker with more than one trait can be caused by the pleiotropic effects of quantitative trait loci related to each other in different traits. For instance, the BA6-1 marker showed positive correlations with fruit weight, fruit crown width, and leaf length. Also, OPG13-3 and BA6-10 markers showed positive correlations with total soluble solids and anthocyanin content. The informative markers identified related to morphological characteristics in pomegranate can be a suitable guide to identify the genotypes with valuable fruit traits. Also, these markers can be used in selecting suitable parents for population generation for mapping purposes.

Relationship between molecular markers and important fruit-related traits in almond (Prunus dulcis [Mill.] D.A. Webb syn. P. amygdalus Batsch) as revealed using multiple regression analysis (MRA).

Almond (Prunus dulcis [Mill.] D.A. Webb syn. P. amygdalus Batsch) is one of the most important nut crops, and its kernel is the edible part that has a high nutritional value and is used in the confectionery and cosmetics industries. The present research aimed to identify random amplified polymorphic DNA (RAPD) and inter simple sequence repeat (ISSR) molecular markers associated with important fruit traits in late-blooming almond genotypes through multiple regression analysis (MRA). The studied genotypes showed significant differences from each other in terms of the measured fruit-related traits. The ISSR primers used produced a total of 125 bands in the studied germplasm, of which 112 showed polymorphic bands. The RAPD primers produced a total of 190 DNA fragments, of which 172 fragments showed polymorphism among genotypes. Some polymorphic fragments of ISSR and RAPD showed significant correlations with the fruit traits measured. Some of these informative markers were associated with more than one trait, which could be caused by the pleiotropic effects of quantitative trait loci related to each other in different traits. For instance, some of the markers showed significant correlations with both nut weight and kernel weight, which indicates a positive correlation between these two traits. Informative markers identified in this study can be used to select suitable parents for population generation for mapping. It is also useful for selecting superior genotypes, especially when information about their genetic basis, such as a linkage map, is not available.

Symbols of Hope on Pediatric Oncology Ward: Children's Perspective Using Photovoice.

Background Hope nurtures confidence and enhances positivity. It is known to be a critical factor in illness, recovery and healing. This study aimed to identify the views of hospitalized children with cancer about the circumstances and factors that create hope for them in the oncology ward. Methods: This qualitative study explored children's experiences using Photovoice, which is an arts-based approach. Twenty children aged 6-12 years diagnosed with various cancers at a Pediatric Hospital in Tehran, Iran, participated in this study. Participants were requested to take photographs of objects, circumstances, or anything that gave them hope or represented a sign of hope in the oncology ward. The photographs were then used to facilitate face-to-face interviews with these children. Data were analyzed using thematic analysis. Results: Data analysis revealed six main themes: emotional connectedness with nursing staff; the playroom as a means to soften the hospital space; the presence of a parent; symbols of recovery; a touch of nature in the hospital setting; and escaping the hospital cage. Discussion: Hopefulness among children can emanate from diverse events and circumstances within the hospital environment. Nurses and physicians need an understanding of children's perspectives to design interventions to improve hopefulness among hospitalized children with cancer.

Children's description of pain through drawings and dialogs: A concept analysis.

AIM: To present a concept analysis of pain in children's drawings and dialogs. INTRODUCTION: The complexity and subjectivity of the concept of pain in children remain ambiguous. As a result, children are exposed to inappropriate diagnosis and inadequate treatment. Children can describe or draw their painful experiences. Analysing the concept of pain based on children's experiences can help identify, assess and properly manage and treat pain in children. DESIGN: Concept analysis. METHODS: Walker and Avant's framework for concept analysis was used in this current study. RESULTS: Major aspects of pain revealed in this concept analysis are affected by children's different concerns about pain. The description of pain in children with chronic diseases or chronic pain is completely different from that in healthy children. Children perceive pain to be internal, external and emotional. Pain in children is associated with poor psychological and emotional conditions, which add new features and aspects to the concept of pain. Children's descriptions and drawings of pain indicate different concepts of pain in their minds. From the perspective of children, pain has an identity that is formed based on reality. CONCLUSION: When developing pain evaluation tools, it is necessary to address the characteristics of pain. In the case of chronic pain, emotional effects of pain on children's psyche need extra attention. Child-based pain management guidelines can then be formulated with the results of relevant concept analyses. Pain assessment is a major part of pain management in children. By considering the characteristics of the concept of pain, the efficiency and usefulness of developed tools can be enhanced to create advancement in paediatric pain management.

Inhibition and structural changes of liver alkaline phosphatase by tramadol.

Tramadol is a potent analgesic drug which interacts with mu-opioid and has low effect on other opioid receptors. Unlike other opioids, it has no clinically significant effect on respiratory or cardiovascular parameters. Alakaline phosphatase is a hydrolase enzyme that prefers alkaline condition and removes phosphate group from different substrates. In this study, the interaction between tramadol and calf liver alkaline phosphatase was investigated. The results showed that tramadol can bind to alakaline phosphatase and inhibit the enzyme in an un-competitive manner. Ki and IC50 values of tramadol were determined as about 91 and 92 µM, respectively. After enzyme purification, structural changes on alakaline phosphatase-drug interaction were studied by circular dichroism and fluorescence measurement. These data revealed the alteration in the content of secondary structures and also conformational changes in enzyme occurred when the drug bound to enzyme-substrate complex.
