RESUMO
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.
RESUMO
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.

Being trans is stigmatized and can make it difficult to fit into the job market in South Korean society. This study explored trans individuals' job-seeking experience and the impact of gender identity on their career choices and development using a qualitative approach. In-depth interviews were conducted with 20 trans adults with job-seeking experiences who were recruited through purposive and snowball sampling in South Korea. Ten subthemes were identified in three overarching themes: (a) limiting myself in job search; (b) challenges in the job application and interview process; and (c) having a desire to build a meaningful career. Participants limited their choices for employment in favor of gender-neutral jobs or trans-inclusive work environments. In the job-seeking process, they faced challenges due to society's rigid binary gender roles and the negative stereotypes about trans identities. Despite stress and identity-related conflict, participants expressed a desire to overcome challenges, build a meaningful career, and flourish at work without compromising their gender identity. This study highlights the experiences of trans individuals in their job-seeking journey. Psychosocial interventions and career support services could help trans individuals in the job-seeking process by identifying their unique challenges to employment and providing assistance to cope with stigma and oppression.
RESUMO
Background: It remains unclear whether lateral joint space narrowing without severe cartilage loss before meniscal allograft transplantation (MAT) affects clinical outcomes and graft extrusion. Hypothesis: Patients with greater preoperative joint space narrowing would show more graft extrusion, more osteoarthritis progression, and worse clinical outcomes than would those with less narrowing. Study Design: Case-control study; Level of evidence, 3. Methods: We retrospectively evaluated 61 patients who underwent lateral MAT and had a minimum follow-up of 4 to 5 years. The median preoperative joint space width (JSW) on Rosenberg view radiographs was used to classify patients into those with less joint space narrowing (JSW ≥3 mm; group A) and greater joint space narrowing (JSW <3 mm; group B). We compared differences between groups in terms of graft extrusion and articular cartilage loss (modified Outerbridge grade ≥3) on 1-year postoperative magnetic resonance imaging (MRI) scans and changes in JSW and clinical outcomes at the last follow-up. Results: There were 31 patients in group A and 30 patients in group B; the mean follow-up time for all patients was 64.4 ± 10.3 months. All patients showed a significant preoperative to postoperative improvement in outcome scores (P < .001 for all). The mean preoperative JSW was 3.8 ± 0.9 mm in group A and 2.3 ± 0.4 mm in group B (P < .001). In group B, there was more graft extrusion on postoperative MRI scans (3.0 ± 0.9 vs 1.9 ± 0.6 mm, respectively; P < .001) and a higher proportion of patients with pathological graft extrusion at final follow-up (43.3% vs 12.9%, respectively; P = .011) compared with group A. At 1 year postoperatively, cartilage loss grade ≥3 was observed at the lateral femoral condyle in 3.2% and 20.0% of patients in groups A and B (P = .053), respectively, and at the lateral tibial plateau in 3.2% and 30.0% of patients (P = .006), respectively. There were moderate correlations between graft extrusion and preoperative absolute JSW (r = -0.471; P < .001) and preoperative relative JSW (r = -0.428; P = .001). Conclusion: Patients with less preoperative joint space narrowing had less graft extrusion and cartilage loss on 1-year postoperative MRI scans, as well as better radiological and clinical outcomes at midterm follow-up, compared with patients with greater preoperative narrowing.
RESUMO
Heat stimulation can promote osteoblast differentiation and bone formation. Combining photothermal therapy and chemotherapy is an effective strategy for treating rheumatoid arthritis (RA). Herein, we prepared chitosan/gelatin/ß-glycerophosphate-melanin-methotrexate (CMM) hydrogel that could be used to perform simultaneous chemotherapy and photothermal therapy for patients with RA. The CMM solution was successfully converted to a gel state at body temperature. Due to intrinsic photothermal properties of melanin, CMM hydrogel exhibited effective temperature increase both in vitro and in vivo with increasing time of near-infrared (NIR) laser irradiation. After NIR laser irradiation, 50 % of methotrexate was rapidly released from the hydrogel within 3 h. Its release rate showed an instantaneous increase with additional NIR laser irradiation. After CMM hydrogel was injected directly into the paw joint of each collagen-induced arthritis (CIA) mouse followed by irradiation with a NIR laser (808 nm, 0.5 W/cm2, 3 min), swelling and redness at the inflamed area were significantly alleviated at 14 days after treatment. Micro-CT analysis confirmed that treated joints of mice were similar to normal joints. Hence, CMM hydrogel could be used as an attractive RA therapeutic agent for simultaneous chemo-photothermal therapy.

BACKGROUND: Visualizing the ultraviolet (UV) dose on skin serve as an intuitive approach to ensure appropriate sunscreen usage and reduce the risk of erythema. UV dose is determined by a number of external factors, such as properties of sunscreens, weather, and type of outdoor activity. We propose a framework for visualizing UV doses that considers various external factors. MATERIALS AND METHODS: First, the skin of a three-dimensional human model was represented using triangular meshes, and various static postures and dynamic motions were simulated to express outdoor activities. Then, we evaluated the persistency and insufficiency properties of sunscreen, which are time dependent and directly affect the effectiveness of the sunscreen skin protection factor (SPF) during UV exposure. Finally, to calculate the UV dose in real time, we tracked the trajectory of the sun and motion of the skin while considering the time-dependent properties of sunscreen. RESULTS: An S/W system was implemented based on the proposed framework to visualize the distribution of UV doses through dynamic color changes in exposed skin areas. The color types include true colors, which represent the minimum erythema dose (MED), and pseudo colors representing states before 1 MED is reached. We devised various examples to discuss the usability of the proposed framework. CONCLUSION: The system conveniently displays the MED according to an individual's skin phototype. When the properties of a wide range of commercial sunscreens are added to the system database, it is expected that the rate of appropriate sunscreen usage by customers will increase.

BACKGROUND: Heat generation in a drug delivery carrier by exposure to near-infrared (NIR) light with excellent tissue transmittance is an effective strategy for drug release and tumor therapy. Because liposomes have amphiphilic properties, they are useful as drug carriers. Liposomes are also very suitable for drug delivery strategies using heat generation by NIR laser because lipid bilayers are easily broken by heat. Thermally generated bubbles from liposomes not only induce drug release, but also enable ultrasound imaging. METHODS: Melanin, perfluorohexane (PFH), and 5-fluorouracil (5-FU)-loaded liposomes (melanin@PFH@5-FU-liposomes) that can generate heat and bubble by NIR laser irradiation were prepared by a thin film method. Conversion of light to heat and bubble generation of melanin@PFH@5-FU-liposomes were evaluated using an infrared (IR) thermal imaging camera and an ultrasound imaging system both in vitro and in vivo. To investigate tumor therapeutic effect, NIR laser of 808 nm was used to irradiate tumor site for 10 min after injecting melanin@PFH@5-FU-liposome into tail veins of CT26-bearing mice. RESULTS: Melanin@PFH@5-FU-liposomes showed a spherical shape with a size of 209.6 ± 4.3 nm. Upon NIR laser irradiation, melanin@PFH@5-FU-liposomes exhibited effective temperature increase both in vitro and in vivo. In this regard, temperature increase caused a phase transition of PFH to induce bubble generation dramatically, resulting in effective drug release behavior and ultrasound imaging. The temperature of the tumor site was increased to 52 t and contrast was greatly enhanced during ultrasound imaging due to the generation of bubble. More importantly, tumor growth was effectively inhibited by injection of melanin@PFH@5-FU-liposomes with laser irradiation. CONCLUSIONS: Based on intrinsic photothermal properties of melanin and phase transition properties of PFH, melanin@PFH@5-FU-liposomes exhibited effective heat and bubble generation upon NIR laser irradiation. The elevated temperature induced bubble generation, resulting in contrast enhancement of ultrasound imaging. Melanin@PFH@5-FU-liposomes under NIR laser irradiation induced the death of cancer cells, thereby effectively inhibiting tumor growth. These results suggest that melanin@PFH@5-FU-liposomes can be utilized as a promising agent for photothermal tumor therapy and ultrasound imaging.
RESUMO
BACKGROUND: The levels of burning susceptibility to ultraviolet (UV) radiations are affected by various factors, including Fitzpatrick skin types, skin color, sex, and ethnicity. However, studies on the relationship between skin biophysical properties and erythemal responses to UV radiations are rare. OBJECTIVE: This study aimed to investigate biophysical properties of the skin that determined individual skin sensitivity to UV radiation. METHODS: As an indicator of skin sensitivity to UV radiation, Korean women were subjected to minimal erythema dose (MED) testing. The skin biophysical properties, such as skin hydration, transepidermal water loss (TEWL), were measured. MED were also evaluated in further variations in the skin, including barrier disruption. RESULTS: A significant negative correlation was observed between TEWL and MED. With an increase in TEWL, that represents reduced skin barrier function, skin UV sensitivity also increased. Artificial alteration of skin conditions also changed erythemal response to UV radiation. When the skin barrier was disrupted, MED significantly decreased, indicating increased skin UV sensitivity. It is hypothesized that the altered penetration of UV radiation into the stratum corneum under the respective skin conditions caused different erythema reactions. CONCLUSION: For the first time in a clinical study, the skin biophysical properties, including skin barrier function, were found to have significant effects on skin sensitivity to UV radiation. This finding could help predict individual susceptibility to UV damage. Therefore, skincare products that improve skin conditions associated with UV sensitivity, as well as sunscreen are important for protection against the hazards of UV radiation.

Increasing consumption of food with high caloric density and a sedentary lifestyle have influenced the increasing obesity prevalence worldwide. The recent pandemic has contributed to this problem. Obesity refers to a state in which lipid accumulates excessively in adipocytes and adipose tissues. Dried heat-killed Enterococcus faecalis (EF-2001) prevents allergic mechanisms, inflammation, and tumor progression. In the present study, we investigated the effects of EF-2001 on high fat diet (HFD)-induced obese rats. The degree of obesity in experimental rats was reduced after 6 weeks of oral administration of 3 mg/kg or 30 mg/kg dosages of EF-2001, indicating regulating effects in rats with HFD-induced obesity. We found that EF-2001 decreased the amounts of total cholesterol, triglyceride, and non-high density lipoprotein (HDL) in HFD-induced obese rats. The effects of EF-2001 on 3T3-L1 adipocytes stained with Oil red O stain are shown in reductions of lipid accumulation, respectively. In addition, we examined the relationships between EF-2001 treatment and mechanisms for the insulin signaling of adipogenesis in 3T3-L1 cells. EF-2001 induced down-regulation in phosphorylation of Erk, JNK, and Akt through the inhibition of insulin receptor phosphorylation. EF-2001 inhibits the expressions of C/EBP-α and PPAR-γ, a lipid metabolism-related transcription factor through confocal microscope observation and Western blot on 3T3-L1 adipocytes and HFD-induced obese rats. Based on our results, intake of EF-2001 significantly prevented HFD-induced obesity in rats through inhibition of C/EBP-α and PPAR-γ in the insulin signaling pathway on lipid accumulation.

PURPOSE: This study aimed to report return to sports (RTS) and return to work (RTW) outcomes after distraction arthroplasty (DA) plus lateral meniscal allograft transplantation (MAT) combined with cartilage repair in active patients with advanced osteoarthritis. It was hypothesised that DA combined with lateral MAT would improve clinical and radiological outcomes and enable RTS and RTW for most patients. METHODS: In total, 21 patients with advanced osteoarthritis (moderate to severe joint space narrowing at lateral edge on Rosenberg view and large cartilage defect of lateral femoral condyle) who underwent concomitant DA and MAT were retrospectively reviewed. Clinical outcomes were assessed using subjective knee scores [Lysholm score, International Knee Documentation Committee (IKDC) subjective knee score, and Tegner activity scale (TAS)] and functional tests (isokinetic extensor muscle strength test, single-leg vertical jump test, and single-leg hop for distance test). The rates of RTS, RTW, and satisfaction were evaluated. Radiological outcomes were assessed using magnetic resonance imaging (MRI) and X-ray (Rosenberg view). RESULTS: The mean age at surgery and mean follow-up duration were 37.2 ± 5.9 years and 37.1 ± 5.4 months, respectively. All improvements in subjective scores were statistically significant (p < 0.001). The Lysholm score improved from 58.3 ± 8.1 to 84.3 ± 8.2, the IKDC subjective score from 53.9 ± 10.4 to 78.0 ± 7.7, and the TAS from 4.0 ± 0.5 to 5.1 ± 0.8. The limb symmetry index (LSI) (%) of the extensor peak torque at an angular velocity of 60°/s improved from 67.3 ± 19.2 to 88.4 ± 20.3% (p = 0.001). The LSI of the single-leg vertical jump test and single-leg hop for distance test improved from 62.8 ± 21.3 to 87.7 ± 19.5% and from 63.9 ± 20.8 to 85.5 ± 18.1%, respectively (all, p < 0.001). All patients were able to return to any sports activity and work. However, 67% and 90.5% returned to their defined or desired level of sports activity and occupation intensity, respectively. Further, 76.2% were very satisfied or somewhat satisfied with the outcome at the last follow-up. The JSW increased by 0.8 ± 0.4 to 2.3 ± 0.6 mm (p = 0.005). In more than 90% of patients, > 50% of cartilage lesion was covered. The mean graft extrusion was 2.6 ± 1.0 mm. CONCLUSION: All patients who underwent distraction arthroplasty plus lateral MAT combined with cartilage repair returned to any sports and work at the last follow-up. Significant improvements in clinical outcomes and the radiographic joint space width were observed. However, the activity ability was somewhat reduced compared with the best preoperative level. This one-stage joint salvage treatment is a promising option for young and active patients with advanced OA who wish to return to high levels of sports activity and occupation intensity (≥ Tegner activity scale 4). LEVEL OF EVIDENCE: III.

This study explored oncologists' experiences of delivering bad news to patients with cancer and their families. Nine oncologists recruited from three superior hospitals in Korea completed in-depth interviews. The results of thematic analyses identified four themes: precursors to bad news delivery, why it is difficult to deliver bad news, when it is more difficult to deliver bad news, and strategies of delivering bad news. The participants felt unprepared for the task and stressed because breaking bad news goes against their responsibility to do no harm and their professional objective to promote healing. Although they were unclear about best practices regarding communication styles, they individualized their communication style to meet the needs of their patients, who have an array of cultural, social, and spiritual backgrounds. Understanding oncologists' perceptions of bad news delivery can inform culturally appropriate interventions for alleviating their stress and improving patient-physician relationships in communication of bad news.

Background: Although CREB phosphorylation is known to be essential in UVB/cAMP-stimulated melanogenesis, CREB null mice did not show identifiable pigmentation phenotypes. Here, we show that CREB-regulated transcription co-activator 3 (CRTC3) quantitatively regulates and orchestrates melanogenesis by directly targeting microphthalmia-associated transcription factor (MITF) and regulating the expression of most key melanogenesis-related genes. Methods: We analyzed CRTC3-null, KRT14-SCF transgenic, and their crossover mice. The molecular basis of CRTC3 effects on pigmentation was investigated by histology, melanin/tyrosinase assay, immunoblotting, shRNA, promoter assay, qRT-PCR, and subcellular localization. These analyses were carried out in primary cultured melanocytes, mouse cell lines, normal human cells, co-cultures, and ex vivo human skin. CRTC/CREB activity screening was performed to identify candidate agents for the regulation of melanogenesis. Results: The coat and skin color of CRTC3-null mice was paler due to a reduction in melanin deposition. Melanogenesis-related genes were reduced in CRTC3-deficient cultured melanocytes and tail skin of CRTC3-null mice. Notably, basal levels of MITF present in CRTC3-null mice were sufficient for melanocytic differentiation/survival. Thus CRTC3-null mice showed a comparable number of epidermal melanocytes compared to control mice. Stem cell factor (SCF) introduction by crossing with KRT14-SCF mice increased epidermal melanocytes and melanin deposition in control and CRTC3-null mice, but the skin color remained still light on the CRTC3-null background. Furthermore, we identified the therapeutic potential of altiratinib to inhibit melanogenesis in human melanocytes and human skin effectively and safely. Conclusion: CRTC3 appears to be a key sensor for melanogenesis and can be used as a reversible and tunable tool for selectively regulating melanogenesis without affecting melanocyte integrity. Thus, CRTC3 can also serve as a screening tool for the discovery of ideal melanogenesis-modulating small molecules.

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.
RESUMO
BACKGROUND: Foreign bodies may be embedded or left behind in the oral cavity during oral surgical procedure. The loss of instruments such as impression material, surgical gauze, and broken injection needles are commonly reported in the dental field. These complications are generally symptomatic and show signs of inflammation, pain, and purulent discharge. Accidental breakage of suture needles is a rare but potentially dangerous event. CASE PRESENTATION: In this report, we present one case of lost suture needle during the procedure of flap operation at local dental clinic and its successful removal under local/general anesthesia administration via CBCT with a help of two reference needles to localize the 6-0 nylon needle and consulting with the clinician. CONCLUSION: CT scanning taken while mouth-closing may not be accurate with regard to real location measurement performed while mouth-opening. If so, other up-to-date radiographic devices and methods to retrieve a needle are recommended.
RESUMO
BACKGROUND: The COVID-19 pandemic has had a significant impact on adults with intellectual disabilities who are dependent on community services. OBJECTIVE: This study explored the experiences of adults with intellectual disabilities from their perspective during the COVID-19 pandemic in South Korea, where most community-based services were suspended. METHODS: We conducted in-depth interviews with 15 adults with intellectual disabilities who lost access to services during COVID-19 pandemic. Inductive thematic analysis was conducted. RESULTS: Five overarching themes emerged: changes in (a) daily life, (b) health behaviors, (c) family relationships, (d) social relationships, and (e) social participation. Most participants experienced the loss of daily routines and healthy behaviors, family conflicts, and social isolation, but they also developed new ways of adapting and finding a new normal. CONCLUSIONS: The findings offer valuable evidence of ways to develop and stabilize community-based services during a pandemic, with insights into the experiences of people with intellectual disabilities.

BACKGROUND: As adults with intellectual disabilities approach older adulthood, they face unique physical and psychosocial challenges. This study explored the lived experiences of middle-aged adults with intellectual disabilities living in their community. METHOD: Six sessions of Photovoice were conducted with a purposeful sample of six middle-aged adults with intellectual disabilities in South Korea. Participants were involved with the theme selection, taking photographs related to the themes, group discussion of photo stories and sharing Photovoice outcomes. RESULTS: Thematic analysis yielded 11 subthemes under the five major themes selected by the participants: health, free time, time in the centre, family and my future in old age. CONCLUSIONS: The study findings showed complex issues middle-aged adults with intellectual disabilities may face in later life, including bereavement and healthy lifestyle concerns. It is important to create a space for meaningful social support and social interactions without stigma.

BACKGROUND: This study aimed to understand parents' concerns about their adult child with intellectual disabilities due to the restriction of community-based services amid the COVID-19 pandemic in South Korea. METHODS: In-depth interviews were conducted face-to-face or by telephone with 19 parents of adult children with intellectual disabilities who had to stop using community-based services. RESULTS: Participants worried that their adult child was not aware of the seriousness of COVID-19, was more susceptible to the COVID-19 virus, could not recognize self-infection and could have fatal consequences of getting infected with COVID-19. They expected challenges in their adult child's life (losing a daily routine, being isolated, regression in skills, becoming bored, lacking physical activities and increased behavioural challenges) but also experienced adjustments and hopes. CONCLUSION: The study demonstrated parents' worry about their adult child becoming infected with COVID-19, highlighting the urgent need for community-based services to address psychosocial challenges during the pandemic.

Celery seeds were fractioned successively by organic solvents, and fractions were screened for their antioxidant properties. Metabolites of high antioxidative fractions were analyzed, and then anti-obesity properties and mechanisms of selected fractions were evaluated in 3T3-L1 adipocytes. Celery seed ethanol extract (CSE) and celery seed ethyl acetate fraction (CSEA) possessed higher in vitro antioxidant properties, including radical scavenging and total phenolic content, than that of hexane, butanol, and water fractions. Total of 43 and 19 metabolites were identified from CSE and CSEA, respectively, by gas chromatography-mass selective detector. Isoferulic acid and p-coumaric acid were only found in CSEA. CSEA possessed higher anti-adipogenesis in the 3T3-L1 cells than CSE by decreasing adipogenic hormones, including leptin and adiponectin. Expression levels of adipocyte-related transcription factors and genes such as C/EBPα, PPARγ, aP2, and FAS decreased to comparable levels of control. CSEA could be used as a natural ingredient with antioxidant and anti-obesity functionality.
RESUMO
BACKGROUND: The proper application of sunscreen is important to ensure protection of the skin against ultraviolet (UV) damage. Sunscreens are used in various ways in real world situations, which alters their UV protection efficacy. In this study, we simulated typical consumer use of sunscreen, which is often sequentially covered with facial makeup, in a laboratory study. METHODS: We compared the sun protection factors (SPF) of sunscreen and makeup products after consecutive layering of the products. RESULTS: The SPF of each sunscreen and makeup product was dramatically lower than stated on the label upon application of a typical amount used by a consumer, which is lower than recommended. For high-SPF products, the drop in effective protection was proportionally greater than those for the low-SPF products upon application of lower doses. However, layering sunscreen and makeup products greatly increased the effective SPF compared with that achieved by single application of each product, even when the amount of each product used was below the recommended level. CONCLUSION: Layering sunscreen with makeup may compensate for insufficient sunscreen application in real-life conditions by providing an additional source of UV protection and improving the homogeneity of coverage. Our results suggest that recommending consecutive application of sunscreen and makeup products may be a practical and useful approach to improving UV protection that would not require additional steps in the facial care routines of many individuals.

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.
