Association between Daily Dietary Calcium Intake and the Risk of Cardiovascular Disease (CVD) in Postmenopausal Korean Women.

We aimed to evaluate the association between daily dietary calcium intake and the risk of cardiovascular disease (CVD) in postmenopausal women using data from the Korean National Health and Nutrition Examination Survey (KNHANES). This cross-sectional study included 12,348 women aged 45-70 years who had reached natural menopause. They were classified into three groups according to daily dietary calcium intake: <400 mg, 400-800 mg, and >800 mg. The risks of CVD, stroke, angina, and myocardial infarction were assessed in each group. Further, we performed subgroup analysis according to the post-menopause duration (≤10 vs. >10 postmenopausal years). We performed logistic regression analysis with adjustment for age, menopausal age, income, urban area, education, insulin use, body mass index, hypertension, diabetes mellitus, dyslipidemia, high alcohol intake, smoking, exercise, oral contraceptive use, and hormonal therapy use. Calcium intake level was not significantly associated with the risk of CVD in the total population and the ≤10 postmenopausal years subgroup. However, in the >10 postmenopausal years subgroup, daily calcium intake >800 mg was associated with significantly decreased risks of all CVD (odds ratio [OR], 0.27; 95% confidence interval [CI], 0.11-0.64), stroke (OR, 0.06; 95% CI, 0.01-0.42), and myocardial infarction (OR, 0.27; 95% CI, 0.11-0.64). Our findings suggest that a dietary calcium intake of >800 mg/day decreases the risk of CVD events in women who have been menopausal for >10 years.

Hormone replacement therapy and breast cancer incidence in Korean women.

OBJECTIVES: After the 2002 Women's Health Initiative (WHI) study, the global use of menopausal hormone therapy (MHT) declined, and despite subsequent studies indicating a low risk of breast cancer, concerns about MHT usage persist. We examined the relationship between changes in MHT use and changes in the incidence of breast cancer from 2002 to 2020 in South Korea. STUDY DESIGN: This study used tumor registry information from 2002 to 2020 from the Korean Statistical Information Service and analyzed the incidence rate of invasive breast cancer in women, who were divided into two age groups: <50 and >50 years. The numbers of MHT prescriptions in Korea between 2002 and 2020 was determined from pharmacy data. RESULTS: The incidence of breast cancer per 100,000 women in South Korea increased from 34.3 in 2002 to 96.4 in 2020. Breast cancer incidence rates increased annually in both groups of women (those aged under and over 50 years), with no significant difference between the two (p = 0.614). Prescriptions for estrogen therapy (ET) in 2020 were 52.7 % lower than those in 2002. Prescriptions for estrogen-progesterone therapy (EPT) decreased by 27.9 % over the same period. Conversely, tibolone prescriptions, which had initially decreased by 25.4 % in 2004, subsequently showed a steady increase and were 93.6 % higher in 2020 than in 2002. CONCLUSION: The incidence of breast cancer increased annually in Korean women of all ages; however, the use of ET and EPT for MHT has declined since 2002, particularly the use of EPT after 2010. MHT, especially EPT, did not significantly increase the incidence of breast cancer in Korean women.

Distinctive CD56dim NK subset profiles and increased NKG2D expression in blood NK cells of Parkinson's disease patients.

Mounting data suggest an important role for the immune system in Parkinson's disease (PD). Previous evidence of increased natural killer (NK) cell populations in PD suggests a potential role of NK cells in the pathogenesis of the disease. Previous studies have analyzed NK cell populations using aggregation by variable expression of CD56 and CD16. It remains unknown what differences may exist between NK cell subpopulations when stratified using more nuanced classification. Here, we profile NK cell subpopulations and elucidate the expressions of activating, NKG2D, inhibitory, NKG2A, and homing, CX3CR1, receptors on NK cell subpopulations in PD and healthy controls (HC). We analyzed cryopreserved PMBC samples using a 10-color flow cytometry panel to evaluate NK cell subpopulations in 31 individuals with sporadic PD and 27 HC participants. Here we identified significant differences in the CD56dim NK subset that changes with disease severity in PD. Furthermore, the expressions of NKG2D in all three NK cell subsets were significantly elevated in PD patients compared to HC. Notably, NKG2A expression in the CD56bright NK subset increased in PD patients with longer disease duration but there were no changes in CX3CR1. In summary, our data suggests that changes in NK cells may be influenced by the clinical severity and duration of PD.

Relationship between menopausal hormone therapy and incidence of fractures in postmenopausal women.

OBJECTIVE: Long-term protective effects of menopausal hormone therapy (MHT) at fractures with different doses and components are controversial. We analyzed the effect of MHT on the incidence of spine and femur fractures according to MHT type, age at commencement, duration and dose of hormones in Korean women. METHOD: This retrospective study evaluated propensity score-matched patients with MHT from the Korean National Health Insurance Service database. Among women aged ≥50 years with menopause between 2004 and 2007, spine and femur fracture incidence until 2017 was analyzed in 36,446 women who had received MHT for >1 year. Estrogen-progesterone therapy (EPT), estrogen-only therapy (ET) or tibolone therapy was conducted. RESULTS: EPT significantly lowered the incidence of spine and femur fractures with a conventional dose, but not with a low dose. Tibolone significantly decreased the incidence of spine fractures in women aged 50-59 years when used for >5 years, and the incidence of femur fractures in women older than 60 years when used for >3 years. ET significantly lowered the risk of femur fractures when estradiol was used for >5 years. CONCLUSION: In menopausal women, all MHT including conventional-dose EPT, ET and tibolone tended to lower the incidence of fractures. The effects, however, varied with the type of fracture and type of MHT.

The Concise Guide to PHARMACOLOGY 2023/24: Introduction and Other Protein Targets.

The Concise Guide to PHARMACOLOGY 2023/24 is the sixth in this series of biennial publications. The Concise Guide provides concise overviews, mostly in tabular format, of the key properties of approximately 1800 drug targets, and about 6000 interactions with about 3900 ligands. There is an emphasis on selective pharmacology (where available), plus links to the open access knowledgebase source of drug targets and their ligands (www.guidetopharmacology.org), which provides more detailed views of target and ligand properties. Although the Concise Guide constitutes almost 500 pages, the material presented is substantially reduced compared to information and links presented on the website. It provides a permanent, citable, point-in-time record that will survive database updates. The full contents of this section can be found at http://onlinelibrary.wiley.com/doi/10.1111/bph.16176. In addition to this overview, in which are identified 'Other protein targets' which fall outside of the subsequent categorisation, there are six areas of focus: G protein-coupled receptors, ion channels, nuclear hormone receptors, catalytic receptors, enzymes and transporters. These are presented with nomenclature guidance and summary information on the best available pharmacological tools, alongside key references and suggestions for further reading. The landscape format of the Concise Guide is designed to facilitate comparison of related targets from material contemporary to mid-2023, and supersedes data presented in the 2021/22, 2019/20, 2017/18, 2015/16 and 2013/14 Concise Guides and previous Guides to Receptors and Channels. It is produced in close conjunction with the Nomenclature and Standards Committee of the International Union of Basic and Clinical Pharmacology (NC-IUPHAR), therefore, providing official IUPHAR classification and nomenclature for human drug targets, where appropriate.

Treatment outcome and prognostic factors in relapsed pediatric acute myeloid leukemia.

Background: Despite improved outcomes for pediatric patients with acute myeloid leukemia (AML), the prognosis for relapse remains poor. This study aimed to examine the clinical factors associated with prognosis in relapsed pediatric AML. Methods: We conducted a chart review of pediatric patients with AML who experienced their first relapse and received treatment at our institution between 2008 and 2019. Risk stratification at diagnosis was performed according to the definition suggested by the ongoing AML 2012 study in Korea, and the clinical factors associated with prognosis were analyzed. Results: A total of 27 pediatric patients with relapsed AML were identified. The 5-year overall survival (OS) and event-free survival (EFS) rates were 32.9% and 32.9%, respectively. A duration ≥12 months from diagnosis to relapse had a favorable impact on survival outcomes (5-yr OS, 64.0% vs. 15.7%; P=0.007). Patients who achieved complete remission (CR) after 1 course of chemotherapy following relapse (N=15) had a 5-year OS rate of 59.3%, while none of the other patients survived (P＜0.0001). Additionally, the 5-year OS differed significantly based on the risk group at initial diagnosis (62.3% [favorable and intermediate prognosis groups, N=11] vs. 13.3% [poor prognosis group, N=15]; P=0.014). Conclusion: Patients with a longer duration of CR before relapse, who achieved CR following 1 course of reinduction chemotherapy, and were in the favorable or intermediate prognosis group at diagnosis demonstrated better outcomes. These findings emphasize the importance of tailoring treatment strategies based on the expected prognosis at relapse in pediatric patients with AML.

Effect of catheter-directed ethanol sclerotherapy on ovarian reserve in patients with recurrent endometrioma: comparative analysis with primary endometriosis.

OBJECTIVE: Catheter-directed ethanol sclerotherapy (CDS) is known to less affect the ovarian function, with comparable efficacy. This study aims to investigate the change in ovarian reserve after catheter-directed ethanol sclerotherapy in patients with recurrent endometrioma, as compared to primary endometrioma. MATERIALS AND METHODS: Retrospective, observational study. Electronic medical records and images of patients with endometrioma who underwent CDS from August 2014 to April 2022 at a single institution were obtained. Patients aged > 18 years old and with anti-Müllerian hormone (AMH) level between 0.8 and 10.0 with regular menstruation were enrolled. Cyst diameter, laterality, AMH level, and CA-125 level before and after 1 month, 6 months, 1 year, 2 years, and 3 years of sclerotherapy were obtained. RESULTS: A total of 180 patients were fit for analysis. There was no statistical difference in age and cyst size between the two groups. Mean values of AMH in each group were 3.35 in the primary group and 3.00 in the recurrent group prior to the procedure (p = 0.347). There was no significant difference in delta value of AMH after sclerotherapy in both groups at each follow-up period. Also, this result was consistent when stratified by laterality, preprocedural AMH level, and initial size of endometrioma. No case of recurrence was reported in both groups. CONCLUSIONS: The effect of CDS on ovarian reserve is not inferior in recurrent endometrioma compared to primary endometrioma. Since sclerotherapy is known to less deteriorate the ovarian function than surgical removal of endometrioma, clinician could consider this as the first-line therapy in patients with recurrent endometrioma. CLINICAL RELEVANCE STATEMENT: Catheter-directed ethanol sclerotherapy for patients with recurrent endometrioma has similar effect on ovarian reserve compared to patients with primary endometrioma. KEY POINTS: • Secondary surgery for endometrioma has significant deleterious effect on ovarian function. • Catheter-directed sclerotherapy (CDS) for endometrioma had equally minimal adverse effect on ovarian reserve, represented as anti-Müllerian hormone (AMH), in both primary and recurrent groups. • Physicians should consider CDS for patients with recurrent endometrioma who desire to preserve ovarian function.

Zika virus modulates mitochondrial dynamics, mitophagy, and mitochondria-derived vesicles to facilitate viral replication in trophoblast cells.

Zika virus (ZIKV) remains a global public health threat with the potential risk of a future outbreak. Since viral infections are known to exploit mitochondria-mediated cellular processes, we investigated the effects of ZIKV infection in trophoblast cells in terms of the different mitochondrial quality control pathways that govern mitochondrial integrity and function. Here we demonstrate that ZIKV (PRVABC59) infection of JEG-3 trophoblast cells manipulates mitochondrial dynamics, mitophagy, and formation of mitochondria-derived vesicles (MDVs). Specifically, ZIKV nonstructural protein 4A (NS4A) translocates to the mitochondria, triggers mitochondrial fission and mitophagy, and suppresses mitochondrial associated antiviral protein (MAVS)-mediated type I interferon (IFN) response. Furthermore, proteomics profiling of small extracellular vesicles (sEVs) revealed an enrichment of mitochondrial proteins in sEVs secreted by ZIKV-infected JEG-3 cells, suggesting that MDV formation may also be another mitochondrial quality control mechanism manipulated during placental ZIKV infection. Altogether, our findings highlight the different mitochondrial quality control mechanisms manipulated by ZIKV during infection of placental cells as host immune evasion mechanisms utilized by ZIKV at the placenta to suppress the host antiviral response and facilitate viral infection.

Association between Fractures and Low Muscle Mass in Korean Menopausal Women: Data from Korean National Health and Nutrition Survey (2010-2011).

OBJECTIVES: This study used the Korean National Health and Nutrition Examination Survey (KNHANES) to determine the association between fractures and low muscle mass. METHODS: This cross-sectional study used the 2010-2011 KNHANES data. Low muscle mass was defined as (appendicular skeletal muscle mass [kg]/Height² [m²]) < 5.45 kg/m², which is < 2 SD below the sex-specific mean of a young reference group. Patients with T-scores between -1.0 and -2.5 indicated osteopenia, whereas those with T-scores lower than -2.5 indicated osteoporosis. RESULTS: Out of 1,306 women enrolled in the study, 330 were diagnosed with low muscle mass according to the abovementioned diagnostic criterion. The prevalence of fractures at various sites was significantly higher in postmenopausal women with low muscle mass than in those without low muscle mass (relative risk [RR], 1.64; odds ratio [OR], 1.62; 95% confidence interval [CI], 1.06-2.48; P = 0.027). Furthermore, the prevalence of fractures was increased by the presence of osteopenia or osteoporosis in addition to low muscle mass (RR, 1.59; OR, 1.60; 95% CI, 1.02-2.49; P = 0.039) and by osteoporosis only (RR, 2.12; OR, 2.29; 95% CI, 1.11-4.70; P = 0.025). CONCLUSIONS: Fracture was more prevalent in postmenopausal women with low muscle mass than in those without low muscle mass. This finding is consistent in a subgroup analysis that included women who had osteoporosis or osteopenia. Moreover, the risk of fractures increased as low muscle mass worsened.

Small RNA sequencing of small extracellular vesicles secreted by umbilical cord mesenchymal stem cells following replicative senescence.

BACKGROUND: Umbilical cord mesenchymal stem cells (UCMSC) are subsets of multipotent stem cells involved in immune modulation, tissue regeneration, and antimicrobial defense. Cellular senescence is associated with the onset of aging-related diseases and small extracellular vesicles (sEVs) are important mediators of senescence and aging. OBJECTIVE: However, little is known about the role and function of microRNAs (miRNAs) carried by UCMSC-derived sEVs. To analyze the expression profiles of miRNAs secreted by senescent UCMSC, small RNA sequencing of the miRNAs within the sEVs was performed in this study. METHODS: UCMSC cultures underwent serial passaging beyond passage number 20 to achieve replicative senescence, which was confirmed by various methods, including increased senescence-associated ß-gal staining and cytokine secretion levels. sEVs derived from non-senescent and senescent UCMSC were isolated and characterized by nanoparticle tracking analysis, transmission electron microscopy, and immunoblot analysis. RESULTS: Small RNA sequencing of the miRNAs within the sEVs revealed senescence-associated differences in the miRNA composition, as shown by the upregulation of miR-122-5p and miR-146a-5p, and downregulation of miR-125b-5p and miR-29-3p. In addition, total RNA sequencing analysis showed that PENK, ITGA8, and TSIX were upregulated, whereas AKR1B10, UNC13D, and IL21R were downregulated by replicative senescence in UCMSC. In sEVs, upregulated genes were linked to downregulated miRNAs, and vice versa. In the gene-concept network analysis, five gynecologic terms were retrieved. CONCLUSIONS: The study provides an insight into the cellular characteristics of UCMSC following replicative senescence and emphasizes the importance of monitoring passage numbers of UCMSC for further therapeutic use.

Psychometric Validation of the Korean Version of the Cancer Survivors' Unmet Needs (CaSUN) Scale among Korean Non-Small Cell Lung Cancer Survivors.

PURPOSE: The purpose of the study was to validate the Korean version of Cancer Survivors' Unmet Needs (CaSUN) scale among non-small cell lung cancer survivors. MATERIALS AND METHODS: Participants were recruited from outpatient clinics at the Samsung Medical Center in Seoul, South Korea, from January to October 2020. Participants completed a survey questionnaire that included the CaSUN. Exploratory and confirmatory factor analysis and Pearson's correlations were used to evaluate the reliability and validity of the Korean version of the CaSUN (CaSUN-K). We also tested known-group validity using an independent t test or ANOVA. RESULTS: In total, 949 provided informed consent and all of which completed the questionnaire. Among the 949 patients, 529 (55.7%) were male; the mean age and median time since the end of active treatment (standard deviation) was 63.4±8.8 years and the median was 18 months. Although the factor loadings were different from those for the original scale, the Cronbach's alpha coefficients of the six domains in the CaSUN-K ranged from 0.68 to 0.95, indicating satisfactory internal consistency. In the CFA, the goodness-of-fit indices for the CaSUN-K were high. Moderate correlations demonstrated the convergent validity of CaSUN-K with the relevant questionnaire. More than 60% of the participants reported information-related unmet needs, and the CaSUN-K discriminated between the needs reported by the different subgroups that we analyzed. CONCLUSION: The CaSUN-K is a reliable and valid measure for assessing the unmet needs in a cancer population, thus this tool help population to receive timely, targeted, and relevant care.

Use of PIRADS 2.1 to predict capsular invasion in patients with radiologic T3a prostate cancer.

Objective: Using multi-parametric magnetic resonance imaging (mpMRI) to identify patients with clinical T3a (cT3a) who were overestimated on mpMRI with final pathological T2 (pT2). To suggest that the neurovascular bundle (NVB) can be preserved by evaluating the characteristics of patients according to their pathological grade among cT3a prostate cancer (PCa) patients using mpMRI. Materials and methods: Patients who underwent robot-assisted laparoscopic radical prostatectomy (RALP) were retrospectively analyzed and those patients with clinical T3aN0M0 were enrolled. These enrolled patients were divided into a localized cancer group with pT2 PCa and a locally advanced group with pT3a or higher. Factors affecting the diagnosis of localized PCa after RALP in patients with cT3a PCa were evaluated. Results: Among the preoperative parameters of patients with cT3a PCa, the prostate specific antigen density (PSAD) (OR: 3.76, 95% CI: 1.85-7.64, p<0.001), international society of urological pathology (ISUP) grade (p<0.05), and index lesion size (OR: 1.44, 95% CI: 1.85-7.64, p<0.001) were significantly associated with pathological locally advanced PCa. Optimal cut-off values for prediction of pT3a or higher were 0.36 ng/mL2 for PSAD (sensitivity: 55.7%, specificity: 70.8%), 1.77 cm for index lesion size (sensitivity: 54.3%, specificity: 66.0%), and 2.5 for ISUP grading (sensitivity: 67.6%, specificity: 53.2%). For prediction of pT3a or higher among patients with cT3a PCa, a nomogram was developed using ISUP grade, index lesion size, and PSAD on prostate biopsy (area under the curve: 0.71, 95% CI: 0.670-0.754, p<0.001). PSAD less than 0.36 index lesion size less than 1.77 cm, and biopsy ISUP grade 1-2 are highly likely to indicate that there is no actual extracapsular extension in cT3a PCa patients. Conclusions: PSAD, ISUP, and index lesion size showed significant associations with the classification of pathologic localized and locally advanced PCa in patients with cT3a PCa. A nomogram including these features can predict the diagnosis of locally advanced PCa in patients with cT3a PCa.

Tibolone and Breast Cancer.

Tibolone, a selective tissue estrogenic activity regulator, is a synthetic steroid with distinct pharmacological and clinical characteristics in contrast to conventional menopausal hormone therapy. Tibolone induces estrogenic activity in the brain, vagina, and bone but remains inactive in the endometrium and breast. In particular, several studies have investigated whether tibolone usage increases the risk of breast cancer. This study aims to determine the effects of tibolone on the breast by focusing on the relation between tibolone use and breast cancer. Our investigation emphasizes recent studies, particularly those based on Asian populations.

Anti-Viral Activities of Umbilical Cord Mesenchymal Stem Cell-Derived Small Extracellular Vesicles Against Human Respiratory Viruses.

The endemic and pandemic caused by respiratory virus infection are a major cause of mortality and morbidity globally. Thus, broadly effective antiviral drugs are needed to treat respiratory viral diseases. Small extracellular vesicles derived from human umbilical cord mesenchymal stem cells (U-exo) have recently gained attention as a cell-free therapeutic strategy due to their potential for safety and efficacy. Anti-viral activities of U-exo to countermeasure respiratory virus-associated diseases are currently unknown. Here, we tested the antiviral activities of U-exo following influenza A/B virus (IFV) and human seasonal coronavirus (HCoV) infections in vitro. Cells were subject to IFV or HCoV infection followed by U-exo treatment. U-exo treatment significantly reduced IFV or HCoV replication and combined treatment with recombinant human interferon-alpha protein (IFN-α) exerted synergistically enhanced antiviral effects against IFV or HCoV. Interestingly, microRNA (miR)-125b, which is one of the most abundantly expressed small RNAs in U-exo, was found to suppress IFV replication possibly via the induction of IFN-stimulated genes (ISGs). Furthermore, U-exo markedly enhanced RNA virus-triggered IFN signaling and ISGs production. Similarly, human nasal epithelial cells cultured at the air-liquid interface (ALI) studies broadly effective anti-viral and anti-inflammatory activities of U-exo against IFV and HCoV, suggesting the potential role of U-exo as a promising intervention for respiratory virus-associated diseases.

New Insights and Implications of Natural Killer Cells in Parkinson's Disease.

Parkinson's disease (PD) is the second most common neurodegenerative disease and is characterized by the loss of dopaminergic neurons in the substantia nigra and the abnormal aggregation and accumulation of the alpha-synuclein (α-syn) protein into Lewy bodies. It is established that there is an association between inflammation and PD; however, the time course of the inflammatory process as well as the immune cells involved are still debated. Natural killer (NK) cells are innate lymphocytes with numerous functions including targeting and killing infected or malignant cells, antimicrobial defense, and resolving inflammation. NK cell subsets differ in their effector function capacities which are modulated by activating and inhibitory receptors expressed at the cell surface. Alterations in NK cell numbers and receptor expression have been reported in PD patients. Recently, NK cell numbers and frequency were shown to be altered in the periphery and in the central nervous system in a preclinical mouse model of PD. Moreover, NK cells have recently been shown to internalize and degrade α-syn aggregates and systemic NK cell depletion exacerbated synuclein pathology in a preclinical mouse model of PD, indicating a potential protective role of NK cells. Here, we review the inflammatory process in PD with a particular focus on alterations in NK cell numbers, phenotypes, and functions.

miR-10a, miR-30c, and miR-451a Encapsulated in Small Extracellular Vesicles Are Prosenescence Factors in Human Dermal Fibroblasts.

Although small extracellular vesicles (sEV) have been reported to play an important role in cellular senescence and aging, little is known about the potential role and function of microRNAs (miRNAs) contained within the sEV. To determine the senescence-associated factors secreted from sEV of human dermal fibroblasts (HDFs), we isolated and characterized sEV from nonsenescent versus that from senescent HDFs. Small RNA-sequencing analysis identified many enriched miRNAs in sEV of senescent HDF, as shown by the upregulation of miR-10a, miR-30c, and miR-451a and downregulation of miR-128, miR-184, miR-200c, and miR-125a. Overexpression of miR-10a, miR-30c, and miR-451a induced an aging phenotype in HDFs, whereas inhibition of these miRNAs reduced senescent-like phenotypes in senescent HDFs. Moreover, treatment with sEV or sEV-containing conditioned medium promoted cellular senescence in HDFs, whereas sEV depletion abrogated prosenescence effects of the senescent HDF secretome. Interestingly, prosenescence sEV miRNAs were found to have an essential role in regulating ROS production and mitophagy activation. Taken together, our results revealed miR-10a, miR-30c, and miR-451a as prosenescence factors that are differentially expressed in sEV of senescent HDFs, showing the essential role of sEV miRNAs in the biological processes of aging.

Coronavirus disease 2019 (COVID-19) vaccine platforms: how novel platforms can prepare us for future pandemics: a narrative review.

More than 2 years after the explosion of the coronavirus disease 2019 (COVID-19) pandemic, extensive efforts have been made to develop safe and efficacious vaccines against infections with severe acute respiratory syndrome coronavirus 2. The pandemic has opened a new era of vaccine development based on next-generation platforms, including messenger RNA (mRNA)-based technologies, and paved the way for the future of mRNA-based therapeutics to provide protection against a wide range of infectious diseases. Multiple vaccines have been developed at an unprecedented pace to protect against COVID-19 worldwide. However, important knowledge gaps remain to be addressed, especially in terms of how vaccines induce immunogenicity and efficacy in those who are elderly. Here, we discuss the various vaccine platforms that have been utilized to combat COVID-19 and emphasize how these platforms can be a powerful tool to react quickly to future pandemics.

Effect of mind and body education on quality of life among young breast cancer patients: a randomized controlled trial.

PURPOSE: This study aim was to evaluate efficacy of the combination with cosmetic and psychosocial education program on body image, sexual function, and emotional function among young-onset breast cancer (YBC). METHODS: An unblended, randomized, controlled trial design was conducted in patients newly diagnosed with stage I-III breast cancer from 2014 to 2015. The intervention group received a structured education program including appearance management and mind control for 4 weeks. The outcome of this study shows effect on body image and sexual functioning and a distress due to altered appearance and anxiety after the intervention and 6 months after intervention. RESULTS: Among 228 eligible patients, 109 (47.8%) agreed to participate in the present study and were randomized to intervention (n = 54) or control (n = 55) groups. After intervention, the intervention group reported significantly better body image compared to the control group (mean score of 75.0 vs. 59.3, respectively; P < 0.01). The intervention group also reported significantly lower levels of distress due to altered appearance and higher levels of sexual functioning compared to the control group after the intervention. The effects were maintained even 6 months after intervention. CONCLUSION(S): Body image intervention for YBC had effect on improving body image and sexual functioning and a reduction in distress due to altered appearance and anxiety. Trial registration number and date of registration: The study was registered at the Clinical Research Information Service (no. KCT0001191, https://cris.nih.go.kr/cris ) on 23 July 2014.

Therapeutic Efficacy of Catheter-directed Ethanol Sclerotherapy and Its Impact on Ovarian Reserve in Patients with Ovarian Endometrioma at Risk of Decreased Ovarian Reserve: A Preliminary Study.

STUDY OBJECTIVE: To investigate the therapeutic efficacy of catheter-directed ethanol sclerotherapy (CDS) and its effect on ovarian reserve in patients with endometrioma at risk of decreased ovarian reserve. DESIGN: Retrospective study. SETTING: Teaching hospital. PATIENTS: We evaluated 18 patients with ovarian endometrioma measuring ≥3 cm and preprocedural serum antimüllerian hormone (AMH) levels of <2 ng/mL. INTERVENTIONS: An 8.5-F catheter was inserted either transabdominally or transvaginally into the endometrioma. After aspiration, sclerotherapy with 99% ethanol was performed, with a subsequent 20-minute ethanol retention. MEASUREMENTS AND MAIN RESULTS: Ultrasonography was performed preprocedurally and 6 months after CDS to evaluate any recurrence or changes in cyst size. Furthermore, serum AMH levels, cancer antigen 125 (CA-125) levels, and the visual analog scale scores for dysmenorrhea were obtained to analyze the ovarian reserve and treatment efficacy, preprocedurally and at 6 months after CDS. The mean cyst size on ultrasonography and serum CA-125 levels decreased 6 months after CDS (p <.001 and p = .001, respectively). All patients reported a decreased visual analog scale score for dysmenorrhea (p <.001). However, the difference in serum AMH levels before and after CDS was statistically insignificant (p = .875). CONCLUSION: CDS was efficacious in reducing pain and serum CA-125 levels in patients with low AMH levels without adversely affecting their ovarian reserve.

RGS10 Reduces Lethal Influenza Infection and Associated Lung Inflammation in Mice.

Seasonal influenza epidemics represent a significant global health threat. The exacerbated immune response triggered by respiratory influenza virus infection causes severe pulmonary damage and contributes to substantial morbidity and mortality. Regulator of G-protein signaling 10 (RGS10) belongs to the RGS protein family that act as GTPase activating proteins for heterotrimeric G proteins to terminate signaling pathways downstream of G protein-coupled receptors. While RGS10 is highly expressed in immune cells, in particular monocytes and macrophages, where it has strong anti-inflammatory effects, its physiological role in the respiratory immune system has not been explored yet. Here, we show that Rgs10 negatively modulates lung immune and inflammatory responses associated with severe influenza H1N1 virus respiratory infection in a mouse model. In response to influenza A virus challenge, mice lacking RGS10 experience enhanced weight loss and lung viral titers, higher mortality and significantly faster disease onset. Deficiency of Rgs10 upregulates the levels of several proinflammatory cytokines and chemokines and increases myeloid leukocyte accumulation in the infected lung, markedly neutrophils, monocytes, and inflammatory monocytes, which is associated with more pronounced lung damage. Consistent with this, influenza-infected Rgs10-deficent lungs contain more neutrophil extracellular traps and exhibit higher neutrophil elastase activities than wild-type lungs. Overall, these findings propose a novel, in vivo role for RGS10 in the respiratory immune system controlling myeloid leukocyte infiltration, viral clearance and associated clinical symptoms following lethal influenza challenge. RGS10 also holds promise as a new, potential therapeutic target for respiratory infections.
