RESUMEN
Immune checkpoint inhibitors (ICIs) exert clinical efficacy against various types of cancers by reinvigorating exhausted CD8+ T cells that can expand and directly attack cancer cells (cancer-specific T cells) among tumor-infiltrating lymphocytes (TILs). Although some reports have identified somatic mutations in TILs, their effect on antitumor immunity remains unclear. In this study, we successfully established 18 cancer-specific T cell clones, which have an exhaustion phenotype, from the TILs of four patients with melanoma. We conducted whole-genome sequencing for these T cell clones and identified various somatic mutations in them with high clonality. Among the somatic mutations, an SH2D2A loss-of-function frameshift mutation and TNFAIP3 deletion could activate T cell effector functions in vitro. Furthermore, we generated CD8+ T cell-specific Tnfaip3 knockout mice and showed that Tnfaip3 function loss in CD8+ T cell increased antitumor immunity, leading to remarkable response to PD-1 blockade in vivo. In addition, we analyzed bulk CD3+ T cells from TILs in additional 12 patients and identified an SH2D2A mutation in one patient through amplicon sequencing. These findings suggest that somatic mutations in TILs can affect antitumor immunity and suggest unique biomarkers and therapeutic targets.

PURPOSE: It was reported that maternal-infant bonding failure predicts abusive parenting. Maternal-infant bonding is important to prevent child abuse. This study aimed to investigate the association between prenatal depressive symptoms, anxiety, cortisol, and oxytocin levels, and postnatal maternal-infant bonding. METHODS: The participants completed a self-report prenatal questionnaire that included the Edinburgh Postnatal Depression Scale (EPDS) and State-Trait Anxiety Inventory (STAI) in the second trimester. Blood and saliva were collected in the second trimester. Cortisol levels were measured in plasma, while oxytocin levels were measured in saliva. Postnatal questionnaires, including the Mother-to-Infant Bonding Scale (MIBS), were administered at 2-5 days, 1 month, and 3 months postpartum. Multiple linear regression and generalized estimating equation (GEE) were conducted for analysis. RESULTS: Sixty-six primiparas participated in the study. Prenatal depressive symptoms (EPDS ≥ 9) and anxiety (STAI-S ≥ 42) were observed in 21.2% and 28.8% of the participants, respectively. The median cortisol and oxytocin levels were 21.0 µg/dL and 30.4 pg/mL, respectively. Multivariate linear regression showed that postnatal social support, prenatal depressive symptoms, anxiety, and salivary oxytocin levels predicted MIBS scores at 2-5 days postpartum. At 1 month postpartum, household income, history of miscarriage, postnatal social support, and prenatal anxiety predicted MIBS scores. At 3 months postpartum, only postnatal social support predicted MIBS scores. The results of GEE showed that prenatal anxiety, oxytocin levels, postpartum period, household income, and postpartum social support were associated with MIBS scores. CONCLUSION: Prenatal depressive symptoms, anxiety, and lower salivary oxytocin levels were predicted to worsen maternal-infant bonding at 2-5 days postpartum. Prenatal anxiety was predicted to cause the same 1 month postpartum. Measuring prenatal depressive symptoms, anxiety, and salivary oxytocin levels may render the assessment of the risk of maternal-infant bonding failure during the early postpartum period and intervene during pregnancy possible.

There is evidence to suggest that soy may be beneficial for prostate cancer patients, but few randomized trials have addressed this. We examined the effect of 6-8 mo soy protein supplementation on prostate specific antigen (PSA) serum levels in men who recurred (PSA > 0.1 ng/ml) within three years of prostatectomy. Sixteen men were randomized to 20 g soy protein (â¼24-26/day genistein; â¼40-43/day total isoflavones) or casein placebo. PSA was measured at base line and at 1, 2, 4, and 6-8 mo. Serum genistein levels greatly increased from baseline and cholesterol decreased in the soy group. In both treatment arms PSA increased similarly and PSA doubling times were not different over the 6-8 mo study duration. Two subjects in each group had stable PSA. A literature search for clinical studies of soy, isoflavones, and PSA revealed that supplementation with soy or isoflavones did not affect PSA in virtually all clinical studies identified. Although this study is too small to draw a definitive conclusion on the effect of soy protein on PSA in men with biochemical failure, the null finding in this study is consistent with the results of virtually all reports of soy and soy isoflavones in the literature.

The mammalian HSP105/110 family consists of four members, including Hsp105 and Apg-1, which function as molecular chaperones. Recently, we reported that Hsp105 knockdown increases sensitivity to the DNA-damaging agent Adriamycin but decreases sensitivity to the microtubule-targeting agent paclitaxel. However, whether the other Hsp105/110 family proteins have the same functional property is unknown. Here, we show that Apg-1 has different roles from Hsp105 in cell proliferation, cell division, and drug sensitivity. We generated the Apg-1-knockdown HeLa S3 cells by lentiviral expression of Apg-1-targeting short hairpin RNA. Knockdown of Apg-1 but not Hsp105 decreased cell proliferation. Apg-1 knockdown increased cell death upon Adriamycin treatment without affecting paclitaxel sensitivity. The cell synchronization experiment suggests that Apg-1 functions in mitotic progression at a different mitotic subphase from Hsp105, which cause difference in paclitaxel sensitivity. Since Apg-1 is overexpressed in certain types of tumors, Apg-1 may become a potential therapeutic target for cancer treatment without causing resistance to the microtubule-targeting agents.

BACKGROUND AND OBJECTIVES: Anti-CD38 monoclonal antibodies, including daratumumab and isatuximab, often interfere with pretransfusion testing. Dithiothreitol (DTT) treatment of red blood cells (RBCs) negates this interference. However, the optimum DTT concentration and treatment time have not been well defined. Here, we quantified CD38 on RBCs before and after DTT treatment using a flow cytometric antibody binding assay (FABA) to specify the optimum conditions for CD38 inactivation. MATERIALS AND METHODS: For FABA, untreated or DTT-treated RBCs were incubated with fluorescein isothiocyanate-labelled anti-CD38 antibody, in the presence or absence of 100-fold or more excess of unlabelled anti-CD38 antibody, and then analysed by flow cytometry (FCM). Dissociation of CD38-positive and control histograms was determined from the D-value using the Kolmogorov-Smirnov test. The results from FABA were compared with those from conventional FCM, indirect antiglobulin test (IAT) and Western blotting. RESULTS: The results from FABA were more consistent than those from conventional FCM. The D-value was found to be reliable in the analysis of difference between CD38 before and after DTT treatment. Our data showed that 0·0075 mol/l DTT for 30 min is sufficient to inactivate CD38 on RBCs. These results were stable and consistent with the findings from IAT. CONCLUSION: Flow cytometric antibody binding assay is an objective way of evaluating the efficacy of DTT treatment for CD38 on RBCs. This approach allows the detection of a small number of cell surface antigens and will be useful for assessing the various chemical treatments to denature RBC antigens.

PURPOSE: A higher peak bone mass (PBM) in adolescence lowers the risk of osteoporosis later in life. This study examined the factors affecting bone mass in female adolescents in relation to lifestyle and environmental factors to promote bone mass development before reaching PBM. DESIGN AND METHODS: The subjects were female students aged 15-16 years and their mothers at a public high school in Osaka, Japan. Bone mass was measured using quantitative ultrasound parameters. The body composition was measured using a multi-frequency segmental body composition analyzer. Nutrient intake, exercise habits, and maternal factors as environmental factors were examined using a questionnaire. RESULTS: Logistic regression analyses revealed that the adolescents' lean mass was significantly related to the BUA (p < .05). The adjusted odds ratio was 1.29 (95% confidence interval [CI]: 1.07-1.54). In contrast, the adolescents' exercise habit was significantly related to the SOS (p < .05). The SOS was significantly higher in the adolescents who exercised >4 times a week than in those who exercised <2-3 times a week. The adjusted odds ratio was 2.83 (95% CI: 1.06-7.56). The adolescents' nutrient intake and maternal factors were not significant factors affecting the adolescents' bone mass. CONCLUSIONS: The present study suggests that increasing lean mass and exercising more than four times a week were important for increasing bone mass in female adolescents. PRACTICE IMPLICATIONS: Nurses should intervene to help female adolescents acquire healthy lifestyle skills and maintain proper body composition and exercise habits to promote bone mass development before reaching PBM.

This study clarifies the association between postpartum depression (PPD) and satisfaction with social support after childbirth through an anonymous survey of 427 postpartum mothers. Mothers' PPD was found to be significantly associated with satisfaction levels regarding formal-instrumental support (OR: 0.32, 95% CI: 0.162-0.632), informal-instrumental support (OR: 0.547, 95% CI: 0.313-0.955), and informal-psychological support (OR: 0.591, 95% CI: 0.384-0.912) in a multivariate logistic regression analysis. To prevent PPD, specialists as formal support providers must provide qualified care based on comprehensive judgments, and families as informal support providers should help with childcare, housework, and mental support.

We examined the effects of cooking and processing on the quantitation of soy protein in various soy-based foods. For the phosphate-buffered saline (PBS) extraction, the total protein content was measured by bicinchoninic acid assay, and the buffer extraction containing sodium dodecyl sulfate (SDS) and 2-mercaptoethanol (ME) was measured by the 2-D Quant Kit, and SDS-polyacrylamide gel electrophoresis analysis (SDS-PAGE) of each extraction was performed. Furthermore, measurements were performed by various ELISAs. During the tofu cooking process, the protein concentrations of soaked soybeans and Seigo (soybean homogenized with water) fluctuated- the change in protein solubility due to the amount of water during sample homogenization was considered to be a factor. It was thought that the decrease in protein concentration due to heating of Seigo during soymilk production was considered to indicate thermal denaturation of the protein, and that SDS and ME extraction in tofu may affect the measurement system. In cooking excluding roasted beans, proteins with a mass of 50 kDa or above and around 20 kDa were denatured, and in twice-fried tofu, proteins around 40 kDa were denatured, but the protein concentration excluding boiled soybeans did not decreased. Furthermore, the protein concentration from roasted beans, yuba, roasted okara and fried tofu increased with the cooking time, suggesting that the denaturation temperature of the protein shifted to a high temperature as the water content decreased. Both of the two types of ELISAs that comply with the official labeling system of foods containing allergenic substances were useful for detecting soybean protein by detecting proteins and peptides in processed soybean products, fermented foods excluding natto, and health foods.

As an East-Asian international study, we evaluated erythrocyte alloimmunity by gender and history of transfusion or pregnancy. In total, data from more than 1,826,000 patients were analyzed, from whom 26,170 irregular erythrocyte antibodies were detected in 22,653 cases. Antibody frequencies in these cases were as follows: anti-E, 26.8%; anti-Lea, 20.0%; anti-P1, 7.1%; anti-M, 6.4%; anti-Mia, 5.6%; anti-c + E, 5.6%; anti-Leb, 4.6%; anti-D, 2.8%; anti-Fyb, 2.6%; anti-Lea+Leb, 2.5%; anti-Dia, 2.0%; and others. For pregnant patients, anti-D (12.7%) was statistically more frequent. For transfused patients, anti-E (37.3%), anti-c + E (9.5%), anti-C + e (3.3%) and anti-Jka (3.1%) were significantly more frequent.

PURPOSE: Peak bone mass, an important determinant of osteoporosis risk, is reached during adolescence. We evaluated the impact of mother-child dyad dietary intervention using the transtheoretical model (TTM) on bone mineral density in Japanese female adolescents. DESIGN AND METHODS: The participants were dyads of female adolescents aged 15-16â¯years and their mothers (who are generally responsible for cooking). We enrolled 92 dyads, with 56 assigned to the intervention group and 36 to the control group. Bone mineral density was measured using quantitative ultrasound parameters (QUS). Nutrient intake and stage of behavioral change were collected via questionnaires. Evaluations were conducted at baseline and seven months later. The intervention group underwent the TTM-based dietary education program for six months. RESULTS: After the intervention program, the ratio of change of the quantitative ultrasound parameter-speed of sound (SOS)-was significantly higher in the intervention than the control group (pâ¯<â¯0.001). Finally, we demonstrated that the intervention was found to significantly affect post-test outcomes in terms of SOS according to the result of analysis of covariance (pâ¯<â¯0.05). CONCLUSIONS: Dietary intervention for female adolescents and their mothers using the TTM may enhance the bone mineral density in female adolescents. PRACTICE IMPLICATIONS: We suggest that dietary intervention for female adolescents and their mothers using the transtheoretical model may enhance the bone mineral density in female adolescents.

BACKGROUND: The use of asthma control guidelines and anti-inflammatory drugs have significantly decreased the number of severe asthma cases including death from asthma. However, there are few prospective cohort studies among pediatric asthma patients in Japan describing the course of asthma symptoms with the treatment taken into consideration. METHOD: We recruited a total of 851 children diagnosed with asthma through 90 hospitals and clinics in 2004 to 2006. Questionnaires were posted annually to collect data on their asthma symptoms, treatment and environmental exposures. We analyzed the disease course in the first 5 years among the children who were registered at age 4 or younger. RESULTS: The disease course of a total of 641 children, aged 2.8+/-1.1 (mean+/-SD) at registration were analyzed. The proportion of children who had intermittent symptoms increased from 37.6% at registration to 86.5% at 5 years, and the proportion of children with intermittent severity increased from 7.0% to 38.9%, showing a significant decrease in the overall severity. The proportion of children using ß2 stimulants decreased from 87.8% at registration to 53.5% at 5 years, while the use of inhaled cortico-steroids were 41.6% at registration and 38.1% at 5 years. CONCLUSION: Most of the children with pre-school onset asthma had their symptoms controlled, and had decreased severity over 5 years.

This study compared the nutritional status before pregnancy, as well as dietary profiles and biomarkers during first trimester, between never-smokers and antenatal quitters among Japanese women. One hundred fifty pregnant women (79 never-smokers and 71 antenatal quitters) from two obstetrics and gynecology clinics were recruited in Japan. Subjects' prepregnancy nutritional status was indicated by their body mass index (BMI). In the first trimester, their dietary profiles were assessed by the Brief Diet-History Questionnaire (BDHQ) and pregnancy outcomes were screened by biomarker tests. Generalized linear regression was used to examine the differences of energy-adjusted dietary intakes and biomarker results between the two smoking groups, with adjustment of maternal age, BMI, gestation week, and parity. The results showed that antenatal quitters were more likely to have a prepregnancy underweight status than never-smokers. During the first trimester, antenatal quitters had significantly higher intakes of unsaturated fatty acids and antioxidants (vegetable lipids and isoflavone), and lower intakes of total cholesterol than never-smokers. Moreover, antenatal quitters had a significantly higher level of serum homocysteine (6.36 nmol/mL vs 4.88 nmol/mL) than never-smokers. In conclusion, antenatal quitters are more likely to have a poor nutritional status before pregnancy than never-smokers. Quitting smoking before pregnancy and having a good nutritional profile during the trimester may not sufficiently reverse the adverse effects of former smoking behaviors on pregnancy outcomes.

BACKGROUND AND OBJECTIVES: Obtaining informed consent (IC) for a blood transfusion is an absolute requirement. In this study, we compared the depth of understanding of blood transfusion among patients with or without an explanation by the transfusion unit staff and evaluated the usefulness of this intervention in obtaining IC. MATERIALS AND METHODS: Expert staff from the transfusion unit started to provide patients with a basic explanation of blood transfusion (intervention group, n = 129). The efficacy of this strategy was assessed by comparison with explanation given by the primary doctors only (conventional group, n = 31). We performed a questionnaire survey to analyze the length of time spent providing information of blood transfusion and the depth of understanding of blood transfusion in the two groups. RESULTS: The median time in providing information in the conventional and intervention groups was 6 and 20 minutes, respectively (P < 0.0001). Patients in the intervention group had a better understanding of several key points on blood transfusion than those in the conventional group. CONCLUSION: Our results show that expert staff from the transfusion unit should be involved in obtaining IC for a blood transfusion. Patients who were provided information by transfusion unit staff were more likely to have a better understanding of the risks and benefits of transfusion.

The establishment of renewable biofuel and chemical production is desirable because of global warming and the exhaustion of petroleum reserves. Sebacic acid (decanedioic acid), the material of 6,10-nylon, is produced from ricinoleic acid, a carbon-neutral material, but the process is not eco-friendly because of its energy requirements. Laccase-catalyzing oxidative cleavage of fatty acid was applied to the production of dicarboxylic acids using hydroxy and oxo fatty acids involved in the saturation metabolism of unsaturated fatty acids in Lactobacillus plantarum as substrates. Hydroxy or oxo fatty acids with a functional group near the carbon-carbon double bond were cleaved at the carbon-carbon double bond, hydroxy group, or carbonyl group by laccase and transformed into dicarboxylic acids. After 8 h, 0.58 mM of sebacic acid was produced from 1.6 mM of 10-oxo-cis-12,cis-15-octadecadienoic acid (αKetoA) with a conversion rate of 35% (mol/mol). This laccase-catalyzed enzymatic process is a promising method to produce dicarboxylic acids from biomass-derived fatty acids.
RESUMEN
Vaccine modified measles (VMM) affects individuals with attenuated vaccine induced immunity. An outbreak of measles occurred in a junior high school, starting from an unvaccinated eighth-grade student who developed natural measles and affected a majority of students who were immunized with a low potent strain of measles vaccine (TD97). To determine whether environmental tobacco smoke (ETS) exposure was associated with the development of VMM in this population, a questionnaire was used asking whether students had VMM symptoms during the outbreak and the smoking status of family members. VMM was defined in the study population as occurrence of fever and/or erythema, along with documented history of measles vaccination. A total of 513 students (85.9%) responded. Overall, the presence of in-house smokers did not differ between VMM students (49.3%) and non-VMM students (50.2%). However, in the ninth grade, presence of an in-house smoker was significantly higher in the family of VMM students (54.0%) than in non-VMM students (36.6%) (P = 0.044). Urinary cotinine levels were also measured in selected students (n = 37). Among families with at least one smoker, urinary cotinine levels were significantly higher in VMM students than in non-VMM students (P = 0.032). Furthermore, a multivariable logistic regression analysis showed that a high urinary cotinine level (>10 ng/mg creatinine; 13.5 percentile) was associated with the development of VMM. Our findings suggest that a high level of ETS exposure may be associated with an increased risk of VMM in a population with attenuated vaccine induced immunity against measles.

BACKGROUND: Hemovigilance is an important aspect of transfusion medicine. However, the frequency of the adverse reactions often varies using different reporters. Recently, we have employed a new information technology (IT)-based in-hospital hemovigilance system. Here, we evaluated changes in practice after implementation of an IT-based reporting system. STUDY DESIGN AND METHODS: We compared the rate of frequency and details of blood transfusion-related adverse reactions 3 years before and after introduction of the IT-based reporting system. Contents and severity of the adverse reactions were reported in a paper-based reporting system, but input by selecting items in an IT-based reporting system. The details of adverse reactions are immediately sent to the blood transfusion unit online. RESULTS: After we introduced the IT-based reporting system, the reported rate of transfusion-related adverse reactions increased approximately 10-fold from 0.20% to 2.18% (p < 0.001), and frequencies of urticaria, pruritus, rash, fever (p < 0.001), hypertension (p = 0.001), tachycardia (p = 0.003), and nausea and vomiting (p = 0.010) increased significantly. Although there was no error report in the paper-based reporting, incorrect reports were observed in 90 cases (0.52%) in the IT-based reporting (p < 0.001). CONCLUSION: The advantages of IT-based reporting were: 1) a significant increase in the frequency of adverse reaction reporting and 2) a significant decrease in underreporting, although the true frequency has yet to be clarified. The disadvantage of the IT-based reporting was an increased incidence of incorrect inputs, all of which was unnoticed by the reporters. Our results showed several important points in need of monitoring after introduction of an IT-based reporting system.

BACKGROUND: This study evaluates the association between Internal Addiction (IA) and psychiatric co-morbidity in the literature. METHODS: Meta-analyses were conducted on cross-sectional, case-control and cohort studies which examined the relationship between IA and psychiatric co-morbidity. Selected studies were extracted from major online databases. The inclusion criteria are as follows: 1) studies conducted on human subjects; 2) IA and psychiatric co-morbidity were assessed by standardised questionnaires; and 3) availability of adequate information to calculate the effect size. Random-effects models were used to calculate the aggregate prevalence and the pooled odds ratios (OR). RESULTS: Eight studies comprising 1641 patients suffering from IA and 11210 controls were included. Our analyses demonstrated a significant and positive association between IA and alcohol abuse (OR = 3.05, 95% CI = 2.14-4.37, z = 6.12, P < 0.001), attention deficit and hyperactivity (OR = 2.85, 95% CI = 2.15-3.77, z = 7.27, P < 0.001), depression (OR = 2.77, 95% CI = 2.04-3.75, z = 6.55, P < 0.001) and anxiety (OR = 2.70, 95% CI = 1.46-4.97, z = 3.18, P = 0.001). CONCLUSIONS: IA is significantly associated with alcohol abuse, attention deficit and hyperactivity, depression and anxiety.

The initial step of blood transfusion therapy is blood type grouping. ABO-mismatch blood transfusion results in serious adverse effects. Several incidents in the process of blood sampling had been experienced in our hospital since 2006 to 2008. Therefore, we have introduced the computed identification system, and the transfusion unit has taken a part of blood sampling. Just after we introduced it in July 2010, only 7% of the doctors and the nurses used the system in blood sampling. Repeated training programs for doctors and nurses on blood sampling procedure improved the utilization to 95%. We realized the importance of our management in face of its introduction. We have to make continuous efforts on the safety of transfusion therapy, because new type of incidents can appear.

Intertrabecular metastasis (ITM) is a type of bone metastasis characterized by tumour growth without significant trabecular changes. ITM is most commonly found in vertebral bodies, and rarely in long bones. We report a solitary rod-shaped ITM of lung adenocarcinoma in the femur.
