Contributing Factors of a Good Death for Children With Cancer From Bereaved Parents' Perspectives in South Korea

Achieving a good-quality death for children with cancer is as paramount as saving their life, given its implications for both the children's end-of-life quality and the grief journey of their parents. This study explored factors contributing to a good death for children with cancer, as perceived by bereaved parents in South Korea. A retrospective survey was conducted, involving 58 bereaved parents of a child who died of cancer. t-tests and regressions were performed to identify factors related to deceased children associated with parents' reports of a good death for children with cancer. The results revealed significant correlations between parents' age, income, religious affiliation, time elapsed since death, child's age at death, and cancer recurrence with several aspects of a good death. These findings underscore the importance of assessing characteristics of both parents and their children to enhance the quality of death experienced by children with cancer in South Korea.

Caregiving Stress Experienced by Parents of Adult Children with Intellectual Disabilities During COVID-19 in Korea

Many of community supports and resources were shattered in the COVID-19 pandemic, leaving parents to navigate caring for their adult child with intellectual disabilities with little support. This study explored caregiving stress experienced by parents of adult children with intellectual disabilities during the COVID-19 pandemic in Korea. In-depth interviews were conducted with 19 parents of an adult child with intellectual disabilities. Thematic analysis yielded two themes: caregiving burden and deteriorating health. Parents bore the brunt of the caregiving burden, spending much of their time helping their adult child with daily activities and managing their challenging behaviors, leaving the caregivers struggling physically and mentally. The heightened caregiver burden and associated deteriorating health among these parents raise serious concerns, indicating a need for immediate support to alleviate these issues and help parents navigate caring for their adult child with intellectual disabilities during the COVID-19 pandemic.

Testosterone promotes the migration, invasion and EMT process of papillary thyroid carcinoma by up-regulating Tnnt1

PURPOSE

To explore the key genes and molecular pathways in the progression of thyroid papillary carcinoma (PTC) promoted by testosterone using RNA-sequencing technology, and to provide new drug targets for improving the therapeutic effect of PTC.

METHODS

Orchiectomy (ORX) was carried out to construct ORX mouse models. TPC-1 cells were subcutaneously injected for PTC formation in mice, and the tumor tissues were collected for RNA-seq. The key genes were screened by bioinformatics technology. Tnnt1 expression in PTC cells was knocked down or overexpressed by transfection. Cell counting kit-8 (CCK-8), colony formation assay, scratch assay and transwell assay were adopted, respectively, for the detection of cell proliferation, colony formation, migration and invasion. Besides, quantification real-time polymerase chain reaction (qRT-PCR) and western blot were utilized to determine the mRNA and protein expression levels of genes in tissues or cells.

RESULTS

Both estradiol and testosterone promoted the growth of PTC xenografts. The key gene Tnnt1 was screened and obtained by bioinformatics technology. Functional analysis revealed that overexpression of Tnnt1 could markedly promote the proliferation, colony formation, migration, invasion, and epithelial-to-mesenchymal transition (EMT) process of PTC cells, as well as could activate p38/JNK pathway. In addition, si-Tnt1 was able to inhibit the cancer-promoting effect of testosterone.

CONCLUSION

Based on the outcomes of bioinformatics and basic experiments, it is found that testosterone can promote malignant behaviors such as growth, migration, invasion and EMT process of PTC by up-regulating Tnnt1 expression. In addition, the function of testosterone may be achieved by activating p38/JNK signaling pathway.

Comparing Perceptions of Addiction Treatment between Professionals and Individuals in Recovery

Background: The purpose of this qualitative study was to compare and contrast the differing perspectives of service users and professionals regarding the current substance use disorders (SUD) services provided in Summit County, Ohio. Seven focus groups were conducted with 44 participants (52.3% male, mean age 46 years), including 15 individuals in recovery, 16 direct service providers, and 13 executive directors. The participants were asked about three areas: (1) effective treatment for SUD, (2) challenges for persons with SUD, and (3) suggestions for improving SUD treatment outcomes. The data were analyzed and coded according to major themes. Results: While there were numerous emergent themes that were concordant between service use and professionals, several differing themes between the groups were also identified. First, participants disagreed on the effectiveness of medication-assisted treatment/Medications for Opioid Use Disorder. Second, professionals identified trauma, stigma, "one-size-fits-all" approach to treatment, and limitations set by managed care act as barriers to treatment, whereas individuals in recovery reported difficulty dealing with feelings, feeling of being rushed into recovery, and the lack of long-term recovery plans as the most significant barriers. Lastly, in order to improve treatment outcomes, professionals emphasized the importance of education unlike individuals in recovery who identified sober supports as the most important factor. Conclusion: This study identified challenges in SUD recovery and highlights essential areas for consideration when developing and implementing SUD treatment. The findings can be used as guidelines to provide better services to individuals with SUDs.Supplemental data for this article is available online at https://doi.org/10.1080/10826084.2022.2058706 .

Changes in Relationships in Bereaved Families: Perspectives of Mothers Who Lost a Child to Cancer

The loss of a child greatly affects the dynamics of interpersonal relationships in bereaved families. This study explored the relationships in bereaved Korean families from the perspectives of mothers after the death of a child due to cancer. We conducted in-depth interviews with 15 bereaved mothers of a deceased child with childhood cancer. Thematic analysis identified 12 subthemes related to bereaved mothers' struggles in grief within three significant themes based on family relationships: (a) relationship with husband; (b) relationship with surviving child or children; and (c) relationships with extended family members. Findings highlight bereaved mothers' need to build supportive family relationships while acknowledging bereaved family members' different grieving styles and their own challenges in grieving the loss of a child.

Cellular viability and death biomarkers enables the evaluation of ocular irritation using the bovine corneal opacity and permeability assay

The BCOP assay is used in the identification of chemicals that cause no ocular irritation or serious damage. However, this method has not been found to adequately discriminate between mild from moderate ocular irritation (category 2A/2B), based upon the animal data. In this study, we aimed to establish methods for discerning ocular irritation by chemicals. We used the BCOP assay and the fluorescence staining methods based on biomarkers for cellular viability and death. The potential for ocular irritation by 12 chemicals from different UN GHS categories was assessed by the BCOP assay. Cryosections of bovine corneas were obtained. The necrotic nucleus was TUNEL labeled, cytoplasmic f-actin was stained by phalloidin while the nucleus was stained by DAPI. The depth of injury (DOI) was then measured. According to BCOP assay, in vivo data of Draize eye test and DOI, the results showed that category NC irritants caused ≤ 10 % epithelial DOI, irritants of category 2B caused >10 % epithelial DOI and showed no stromal damage, while category 2A showed damage to the stroma. Based on these results, the GHS prediction model could distinguish between GHS 2A and 2B. Authenticating the viability of BCOP by DOI measurements can provide a more reliable basis for classifying ocular irritants.

A photovoice study on the bereavement experience of mothers after the death of a child

This study explored the bereavement experience of mothers after losing a child to cancer in Korea, using photovoice. The mothers took photos reflecting five subject areas they selected: (a) if I had one more day with my child, (b) memories with my child, (c) dreaming of my child's healthy future, (d) what gave me strength, and (e) fulfilling my child's wishes for the future. The findings show that mothers who lost a child to cancer need bereavement care to promote well-being. This study can help pediatric oncology providers develop bereavement interventions that address parental grief and improve quality of life.

Maternal Depressive Symptoms, Adolescent Daughters' Substance Use, and Father Residence in Minority Families

Background: Maternal depression has been linked to substance use in adolescents, but the mechanisms of the relationship between maternal depression and adolescent substance use are less clear. Specifically, previous literature has overlooked the role of fathers as a potential protective or exacerbating factor in buffering this relationship. Objectives: The goal of this study was to investigate the association between maternal depressive symptoms and adolescent substance use, exploring father's residential status as a moderator for adolescents living with a mother with depressive symptoms. Method: Paper-and-pencil surveys were administered to a sample of 176 mothers and their adolescent daughters aged 14-18, predominantly identifying as African American/Black. Participants included a subset of mothers with HIV. Results: The results revealed that maternal depressive symptoms were not directly associated with adolescent substance use. However, father's residential status was found to be a significant moderator in the relationship between maternal depressive symptoms and adolescent substance use. Specifically, when fathers were involved in the daughter's life (residential or non-resident), substance use was higher in adolescents of mothers with high depressive symptoms than in those of mothers with low depressive symptoms. Conclusion: The results suggest that varied family dynamics are critical to understanding engagement in substance use among adolescent girls, including the influence of both mothers and fathers.

Experiences of Korean mothers of children with cancer: A Photovoice study

Using Photovoice, a participatory action research methodology, we investigated Korean mothers' lives postdiagnosis of their child with cancer. Photovoice was used to understand the mothers' perceptions of how they have adapted to their children's illnesses. Five mothers of children with cancer participated in five sessions of the Photovoice project, during which they took and shared photographs and narratives about their experiences and joined weekly group discussions on their selected themes. The following themes and subthemes emerged: "What I would like to do (taking a break, socializing with friends, spending time with other family members, developing my career)," "My child and food (whatever my child wants to eat, love of family)," "My days for my child (doing what my child wants to do, being a playmate, changing for my child)," and "Power sources for me (family, courage of children, mom is strong, hope)." Having a child with cancer greatly affects the mother's social and work lives as well as emotional well-being. Services and programs such as respite care, parenting education, and psychological support are recommended based on the study findings.

Parentification, substance use, and sex among adolescent daughters from ethnic minority families: the moderating role of monitoring

Guided by structural family systems theory, this study explored the relationship between parentification and adolescent daughters' sexual risk engagement and substance use. We also explored how adolescent reports of parental monitoring moderated the relationship between parentification and adolescent risk. Data were from a cross-sectional, cross-generational study of 176 mother-daughter dyads from low-income, inner-city, ethnic minority families. In this sample, which included a subset of mothers with HIV, parental physical symptoms were associated with slightly higher levels of parentification. Parentification was associated with adolescent daughters' intention to have sex (but not substance use) in a direction opposite to prediction. Higher parentification was associated with lower intention to have sex. Parental monitoring did not moderate relationships between parentification and adolescent risk. These findings highlight that despite the negative influence hypothesized in structural family systems theory, parentification was not associated with risk engagement of high-risk adolescent daughters in ethnic minority families with low income.

Abstract PD5-3: Anti-metastatic activity, chemotherapeutic enhancement and therapeutic potential of targeting Hsp90 with ganetespib in triple negative breast cancer

Background: While the incidence of triple negative breast cancer (TNBC) is only 10-20%, these tumors show a disproportionate mortality for breast cancer patients. Due to a lack of effective molecular targets in this disease, therapeutic options are largely limited to systemic chemotherapeutic approaches which have shown disappointing efficacy in the metastatic setting. Here we undertook a comprehensive evaluation of the activity of the drug candidate, ganetespib, a potent inhibitor of heat shock protein 90 (Hsp90), in this malignancy.

Methods: The sensitivity of TNBC cells to ganetespib was determined in viability assays using a panel of tumor lines. The effects of ganetespib exposure on client proteins and their effector pathways were examined by Western blot and reverse phase protein array analysis. The anti-metastatic activity of ganetespib was evaluated using a 4T1 metastasis model. Combinatorial drug analyses were performed with chemotherapeutic agents. DNA damage and cell cycle disruption were assessed using the comet assay, Western blotting and fluorescence microscopy. The in vivo efficacy of the compound, both as a single agent and in combination, was established using MDA-MB-231 xenograft models. Computed tomography scans were obtained for a metastatic TNBC patient undergoing ganetespib treatment.

Results: Ganetespib reduced cell viability in TNBC cell lines with low nanomolar potency. Ganetespib treatment induced robust destabilization of multiple client proteins and oncogenic signaling pathways and suppressed lung metastasis in the experimental model. Ganetespib potentiated the cytotoxic activity of doxorubicin via enhanced DNA damage and mitotic arrest, conferring superior efficacy to the doxorubicin + cyclophosphamide (AC) regimen in MDA-MB-231 xenograft models. Ganetespib also promoted mitotic catastrophe and apoptosis in combination with taxanes in vitro, and these effects translated to significantly improved combinatorial activity in vivo. Marked tumor shrinkage of metastatic lung lesions was seen in the patient while on ganetespib monotherapy.

Conclusion: The preclinical activity profile and clinical evidence of tumor regression suggest that ganetespib offers considerable promise as a new therapeutic candidate to target TNBC. In particular, the capacity of ganetespib to potentiate the activity of standard of care chemotherapeutics provides a rationale for the exploration of this agent in novel combinatorial treatment strategies for this disease.

Child neglect: definition and identification of youth's experiences in official reports of maltreatment

OBJECTIVE

The purpose of this study was to describe the nature of neglect in child welfare clients, to describe these experiences, to examine its typologies, and to understand how different types of neglect co-occurred with each other and with other types of maltreatment.

METHODS

Case record abstraction was conducted on the child welfare case records of an urban, ethnically-diverse sample of youths (n=303) identified as maltreated by a very large public child welfare agency. We utilized the Maltreatment Case Record Abstraction Instrument (MCRAI) which was based on the work of Barnett et al. (1993) as modified by English and LONGSCAN (1997). Thirteen items of parental behavior deemed neglectful were coded and organized into 5 subtypes of neglect (care neglect, environmental neglect, medical neglect, educational neglect, supervisory neglect).

RESULTS

Neglect was present in 71.0% of the sample as compared to the 41.0% classified as neglected by CPS records. Neglect was accompanied by other types of maltreatment in 95% of the cases. Children who were neglected had more reports of maltreatment and experienced a greater number of different types of maltreatment than those who were maltreated, but not neglected. The most common type of neglect was supervisory neglect (72.5%) followed by environmental neglect (61.6%). With the exception of medical neglect, all types of neglect were significantly correlated with each other.

CONCLUSIONS

The abstraction resulted in rich data showing that under a one-word label of neglect, the nature of neglect that the youngsters actually experienced was quite diverse and heterogeneous in its phenomenology. Furthermore, neglect is pervasive for children in the child welfare system and official classifications underestimate its occurrence. Neglect does not happen in isolation; children who are reported as neglected are likely to experience other forms of maltreatment.

PRACTICE IMPLICATIONS

Official classifications should not be used in determining interventions for children and families. Interventions for neglected youngsters should be individualized to address the complexity of children's experiences.

Emotional abuse in a sample of multiply maltreated, urban young adolescents: issues of definition and identification

OBJECTIVE

The main purpose of this paper is to use the Brassard and Donovan [Brassard, M. R. & Donovan, K. L. (2006). Defining psychological maltreatment. In M. M. Freerick, J. F. Knutson, P. K. Trickett, & S. M. Flanzer (Eds.), Child abuse and neglect: Definitions, classifications, and a framework for research (pp. 151-197). Baltimore, MD: Paul H. Brookers Publishing Co., Inc.] framework to examine and describe the nature of emotional abuse experienced by a sample of urban, ethnically diverse male and female youth (N=303) identified as maltreated by a very large public child welfare agency.

METHODS

Case record abstraction was conducted on the DCFS records of these maltreated youth using the Maltreatment Case Record Abstraction Instrument (MCRAI) which was based on the work of Barnett et al. [Barnett, D., Manly, J. T., & Cicchetti, D. (1993). Defining child maltreatment: The interface between policy and research. In D. Cicchetti & S. L. Toth (Eds.), Advances in applied developmental psychology: Child abuse, child development and social policy (pp. 7-73). Norwood, NJ: Ablex Publishing Corp.] as modified by English and LONGSCAN [English, D. J., & the LONGSCAN Investigators. (1997). Modified maltreatment classification system (MMCS). Retrieved from http://www.iprc.unc.edu/longscan/]. Fifteen items of parental behavior deemed emotionally abusive were coded and organized into four subtypes of emotional abuse (spurning, terrorizing, isolating, exploiting/corrupting) using the Brassard and Donovan (2006) framework.

RESULTS

Using this coding system, almost 50% of the sample were found to have experienced emotional abuse in contrast to 9% identified at the time of referral by DCFS. Most of the emotionally abused youth also experienced physical abuse (63%) and/or neglect (76%) as well. The most frequent subtype of emotional abuse experienced was terrorizing. Most youth experienced more than one subtype.

CONCLUSIONS

Emotional abuse, while frequent, was seldom the focus of the child protection services investigation. The nature of this abuse was not minor, but rather likely to be dangerous to the mental health and well-being of these children. Further more emotional abuse, in this sample of young adolescents, at least, was likely to be accompanied by other forms of maltreatment, especially physical abuse and/or neglect. These findings have important implications for practice and the direction of future research.

PRACTICE IMPLICATIONS

All those who interact with child welfare clients must recognize the prevalence of emotional abuse in maltreated children so that appropriate interventions are instituted. Screening for emotional abuse should be part of all intake referrals and when confirmed should be noted in official records. When children are placed, foster parents (both kin and non-kin) need training on the prevalence and consequences of emotional abuse, and strategies to help their foster children recover from the aftermath. When children remain with maltreating parents, emotional abuse should be a focus of the interventions designed to help maltreating parents with more effective parenting strategies and also should be a focus of the interventions designed to help the child recover from the consequences of maltreatment.

Effects of mechanical forces on lung-specific gene expression

Fetal breathing movements (FBM) are necessary for fetal lung growth and maturation. The authors analyzed fetal rat lungs cultured with or without lung distension and tracheal ligation, and examined the effects of mechanical stretch on a human pulmonary epithelial cell line (NCI-H441) that shows regulated expression of surfactant proteins (SP-A, SP-B). Cells were grown on silastic membranes and mounted in a Flexercell Strain Unit. Cyclic deformation simulating FBM was achieved by applying a vacuum of 22 kPa (5%-15% radial deformation) at 50 cycles per minute for 2 to 24 hours. Results indicate that static distension for as little as 4 hours decreased steady-state SP-A and SP-B mRNA levels in whole lung (n = 5-6, P < .01). In contrast, cyclic stretching of H441 cells for 24 hours increased SP-B and SP-A expression 2- to 4-fold over controls. Cyclic deformation also significantly enhanced 3H-choline incorporation into saturated phosphatidylcholine. Dynamic mechanodeformation may be a critical stimulus for fetal lung development.

[Studies on the fermentation technology of microbiological preparation No.633]

Cloning of cDNAs from a mammalian expression library by a direct selection-amplification method

A sensitive method was devised for cloning cDNAs from a mammalian expression library based on single-cell detection and selection of transfected cells. The method is applicable for cloning cell-surface or cytoplasmic proteins for which a detection assay, such as immunofluorescence or immunohistochemical reactivity, exists. The widely used eukaryotic expression vector cdm8 is utilized, and the method is demonstrated using the gene for C-CAM, a liver glycoprotein adhesion molecule. After transfection, cells are plated out on a collagen gel substrate to allow retrieval of selected cells. Simultaneous fixation and permeabilization with acetone permits immunological and histochemical detection of cell-surface and cytoplasmic proteins without loss of plasmid vector. Inserts of interest are recovered by PCR with vector primers.

TA1, a highly conserved oncofetal complementary DNA from rat hepatoma, encodes an integral membrane protein associated with liver development, carcinogenesis, and cell activation

Hepatocellular carcinoma is characterized by changes in gene expression associated with cell growth and differentiation. Cell surface antigenic changes have also been described based on differential antibody reactivity between normal and neoplastic liver. We obtained a novel tumor-associated cDNA designated TA1 on the basis of its differential expression between hepatoma cells and normal liver. Sequence analysis predicted a 723-base pair open reading frame with the deduced amino acid sequence encoding an integral membrane protein containing multiple hydrophobic transmembrane domains. Database searches revealed TA1 as the likely rat homologue of E16, a recently cloned human cDNA associated with lymphocyte activation. Although noncoding sequences diverged significantly, the 95% conservation of the predicted proteins between species strongly suggests an important, although as yet undefined, function in normal cells. TA1 transcripts were detected in normal adult rat tissues including testes, brain, ovary, spleen, mammary gland, and uterus with the highest steady-state expression in placenta. Although no expression was detected in normal liver, all rat hepatomas examined expressed an abundant 3.2-kilobase transcript. TA1 expression was closely associated with progression in this tumor model and suggests this molecule, originally linked to cell activation, also plays a role in the malignant phenotype.

[The effects of mupirocin on burned wound with Staphylococcus aureus infection]

The therapeutic results of 41 cases of S. aureus infected burn wound (average 2.1% TBSA, approximately 200 cm2) treated with Mupirocin are reported in this paper. The effects of Mupirocin was obviously superior to that of SD-Ag used in control group. During the observation period the total effective rate of the studied group was 88.9% (control group: 70%, P < 0.05) and the bacterial clearance rate of S. aureus from the wound was 88.8% (control group: 40% P < 0.05). The sensitivity of 30 strains of S. aureus isolated from burn wounds to 11 varieties of antibiotics indicated that the sensitive rate to Mupirocin was as high as 92.68%, only lower that Vanconmycin. The bacteriological assay (MIC < or = 0.25 mg/L, MIC < or = 4 mg/L) also showed high sensitivity of S. aureus to Mupirocin. We suggest Mupirocin be the first choice of topical antibacterial agents for burn wound with S. aureus infection, especially for infection with MRSA.

[Immune function of rheumatoid arthritis treated by medicated-bath therapy in Tibetan medicine]

The changes of the immune function of rheumatoid arthritis before and after the Tibetan medicated-bath was observed. It showed a higher level of the rheumatoid factor (RF) titre, immunoglobulin (Ig) G, M, A and CD4 cells, but the CD8 cells was obviously lower before the treatment. Clinical data indicated that the medicated-bath had significant effective rate. In order to elucidate the mechanism of the medicated-bath upon rheumatoid arthritis the RF titre, Ig level, complement C3, 3H-TdR incorporated with lymphocytes transformation and CD3, CD4, CD8 cell level were assayed. Results showed that RF titre decreased after the bath and the negative transforming rate reached 70.6%, Ig level obviously dropped as well as the number of CD4 cells while CD8 cell level increased. The transforming stimulation index of lymphocyte cells obviously decreased. All of the above mentioned showed that there was a higher concentration of the enhancing factor of interleukin-2 (IL2-EF) involved in lymphocyte culture of rheumatoid arthritis patients. They suggested that the Tibetan medicated-bath had an immunomodulating effect on rheumatoid arthritis patients through increasing the level of CD8 cells and reducing CD4 cells.

Who cares? Psychological stress in the operating department nurse

The operating department nurse is subject to many stressors and while there is an optimum level of stress where nurses function at their best, too much may be detrimental both to nurses--and their patients. Jean Sang looks at the subject of stress and discusses the findings of her research.
