RESUMEN
(1) Background: The number of severely obese patients worldwide is rapidly increasing. Recently, novel therapeutic approaches, such as bariatric surgery or GLP-1 receptor agonists, have emerged, bringing about a paradigm shift in this field. However, these therapies sometimes face challenges, such as peri-surgical complications or supply shortages. Mazindol, which is an appetite suppressant approved decades ago in Japan, remains a valuable option. In this study, we investigated the effectiveness of mazindol in reducing body weight in 147 patients, and we examined the factors influencing said effectiveness. (2) Methods: The patients were divided into four groups based on the treatment cycles they underwent: 1 cycle, 2 cycles, 3-5 cycles, and over 6 cycles. We compared the changes in body weight before and after the treatment among these four groups. Additionally, we sought to identify the factors correlated to the effectiveness of mazindol. (3) Results: The change in body weight was more pronounced in the group which underwent 3-5 cycles compared to the groups which underwent 1 cycle and 2 cycles; this change was also more pronounced in the group which underwent over 6 cycles compared to those which underwent 1 cycle. Furthermore, we observed a significant correlation between the initial body weight and the extent of body weight change. (4) Conclusions: Mazindol demonstrated effectiveness in reducing the body weight of patients in a cycle-dependent manner.
RESUMEN
BACKGROUND: It is known that heparinoid, a mucopolysaccharide polysulfate, is effective in improving rough skin and promoting blood circulation as medicines for diseased areas. However, heparinoid has a molecular weight of more than 5000 and cannot penetrate healthy stratum corneum. OBJECTIVE: We tested the efficacy of sulfated oligosaccharides with a molecular weight of less than 2000 on the human skin barrier function and moisturizing function. METHODS: We measured the transepidermal water loss (TEWL) of a three-dimensional human epidermis model cultured for 3 days after topical application of sulfated oligosaccharides, then observed the effects on TEWL suppression. The mRNA levels of proteins involved in intercellular lipid transport and storage in the stratum corneum, and moisture retention were measured using RT-qPCR. RESULTS: An increase in the mRNA levels of the ATP-binding cassette subfamily A member 12 (ABCA12), which transports lipids into stratum granulosum, was confirmed. Increases were also observed in the mRNA levels of filaggrin (FLG), which is involved in the generation of natural moisturizing factors, and of caspase-14, calpain-1 and bleomycin hydrolase, which are involved in the degradation of FLG. Antibody staining confirmed that the application of sodium trehalose sulfate to 3D model skin resulted in more ABCA12, ceramide, transglutaminase1, and FLG than those in controls. In a randomized, placebo-controlled, double-blind study, participants with low stratum corneum water content applied a lotion and emulsion containing sodium trehalose sulfate to their faces for 4 weeks. Sodium trehalose sulfate decreased the TEWL and increased the stratum corneum water content. CONCLUSION: These results suggest that cosmetics containing sodium trehalose sulfate act on the epidermis by increasing barrier factors and moisturizing factors, thereby ameliorating dry skin.

(1) Background: Although the diagnostic criteria for massive hemorrhage with organ dysfunction, such as disseminated intravascular coagulation associated with delivery, have been empirically established based on clinical findings, strict logic has yet to be used to establish numerical criteria. (2) Methods: A dataset of 107 deliveries with >2000 mL of blood loss, among 13,368 deliveries, was obtained from nine national perinatal centers in Japan between 2020 and 2023. Twenty-three patients had fibrinogen levels <170 mg/dL, which is the initiation of coagulation system failure, according to our previous reports. Three of these patients had hematuria. We used six machine learning methods to identify the borderline criteria dividing the fibrinogen/fibrin/fibrinogen degradation product (FDP) planes, using 15 coagulation fibrinolytic factors. (3) Results: The boundaries of hematuria development on a two-dimensional plane of fibrinogen and FDP were obtained. A positive FDP-fibrinogen/3-60 (mg/dL) value indicates hematuria; otherwise, the case is nonhematuria, as demonstrated by the support vector machine method that seemed the most appropriate. (4) Conclusions: Using artificial intelligence, the borderline criterion was obtained, which divides the fibrinogen/FDP plane for patients with hematuria that could be considered organ dysfunction in massive hemorrhage during delivery; this method appears to be useful.

AIM: To evaluate the usefulness of transabdominal sonographic confirmation of placental detachment in preventing uterine inversion. METHODS: This was 14-year retrospective cohort study that included women who had transvaginal deliveries in our hospital. We introduced routine transabdominal ultrasonography during placental delivery to prevent uterine inversion. Followed by the confirmation of placental detachment by ultrasonography, we started placental delivery procedure. The frequency of uterine inversion during placental delivery was compared before and after the ultrasonography was introduced. Moreover, the duration of the third stage of labor and bleeding volume during labor were compared between the ultrasonography performing group (USG group) and the non-performing group (non-USG groups). RESULTS: Five thousand and eighty-one women, including 1724 and 3357 women who delivered before and after the ultrasonography was introduced, respectively. The frequency of uterine inversion after the introduction of the ultrasonography system was significantly reduced compared to that before the introduction (0.03% vs. 0.23%, p = 0.03). Even after the introduction of ultrasonography, the actual rate of performing ultrasonography remained 54.1% due to various restrictions. The mean duration of the third stage of labor in the USG group was slightly longer than that in the non-USG group (8.4 ± 5.0 vs. 6.8 ± 3.6, p < 0.01). The mean bleeding volume during labor in the USG group was higher compared with the non-USG group (457 ± 329 vs. 418 ± 285, p < 0.01). CONCLUSIONS: Transabdominal sonographic confirmation of placental detachment may be useful in preventing uterine inversion.

BACKGROUND: Evidence on the association between severe maternal morbidity (SMM) and mother-infant bonding and self-harm ideation is limited. We aimed to examine these associations and the mediating effect of Neonatal Intensive Care Unit (NICU) admission at one-month postpartum. METHODS: This multicenter, prospective cohort study was conducted in Japan (n = 5398). SMM included preeclampsia, eclampsia, severe postpartum hemorrhage, placental abruption, and a ruptured uterus. Lack of affection (LA) and Anger and Rejection (AR) were assessed using the Mother-Infant Bonding Scale (MIBS), and self-harm ideation was assessed using the 10th item of the Edinburgh Postnatal Depression Scale (EPDS). Linear and logistic regression models were used to examine the association between SMM and MIBS score and self-harm ideation. A structural equation model (SEM) was employed to examine the mediating effect of NICU admission on the association between SMM and mother-infant bonding and postpartum depressive symptoms. RESULTS: Women with SMM had a 0.21 (95 % confidence interval [CI]: 0.03-0.40) point higher MIBS score and a decreasing trend in the risk of self-harm ideation (odds ratio 0.28, 95 % CI: 0.07-1.14) compared to those without SMM. SEM analysis revealed that SMM was associated with MIBS partially through NICU admission. LIMITATIONS: EPDS scores during pregnancy could be an unmeasured confounder. CONCLUSIONS: Women with SMM had higher MIBS scores, particularly on the LA subscale, which was partially mediated by NICU admission. Psychotherapy to support parent-infant relationships is necessary for women with SMM.

BACKGROUND: This study aimed to assess the long-term effects of tofogliflozin, a sodium-glucose cotransporter 2 (SGLT2) inhibitor, on atherosclerosis progression and major clinical parameters in patients with type 2 diabetes lacking an apparent history of cardiovascular disease. METHODS: This was a prospective observational 2-year extension study of the "Using TOfogliflozin for Possible better Intervention against Atherosclerosis for type 2 diabetes patients (UTOPIA)" trial, a 2-year randomized intervention study. The primary endpoints represented changes in the carotid intima-media thickness (IMT). Secondary endpoints included brachial-ankle pulse wave velocity (baPWV) and biomarkers for glucose metabolism, lipid metabolism, renal function, and cardiovascular risks. RESULTS: The mean IMT of the common carotid artery (IMT-CCA) significantly decreased in both the tofogliflozin (- 0.067 mm, standard error 0.009, p < 0.001) and conventional treatment groups (- 0.080 mm, SE 0.009, p < 0.001) throughout the follow-up period; however, no significant intergroup differences in the changes (0.013 mm, 95% confidence interval (CI) - 0.012 to 0.037, p = 0.32) were observed in a mixed-effects model for repeated measures. baPWV significantly increased in the conventional treatment group (82.7 ± 210.3 cm/s, p = 0.008) but not in the tofogliflozin group (- 17.5 ± 221.3 cm/s, p = 0.54), resulting in a significant intergroup difference in changes (- 100.2 cm/s, 95% CI - 182.8 to - 17.5, p = 0.018). Compared to the conventional treatment group, tofogliflozin significantly improved the hemoglobin A1c and high-density lipoprotein cholesterol levels, body mass index, abdominal circumference, and systolic blood pressure. The frequencies of total and serious adverse events did not vary significantly between the groups. CONCLUSIONS: Tofogliflozin was not associated with improved inhibition of carotid wall thickening but exerted long-term positive effects on various cardiovascular risk factors and baPWV while showing a good safety profile.

BACKGROUND: Adverse child experiences (ACEs), childhood maltreatment and household dysfunction, are risk factors of hyperglycemia in pregnancy (HIP), including diabetes before pregnancy, gestational diabetes (GDM), and overt diabetes in pregnancy, through increased risk of unhealthy behaviors, obesity, and stress response system dysfunction. While ACEs are often difficult to be assessed in hospital settings, parent-daughter relationship, that is, pregnant women's relationship with their parents can be considered as a measurable maker for ACEs that may be associated with HIP. The purpose of this study is to examine the association between poor parent-daughter relationship and HIP. METHODS: Hospital-based prospective cohort study was conducted in Japan (N = 6,264). Women visiting participating 58 facilities for delivery between April 2019 and March 2020 were included. Parent-daughter relationship was assessed by a questionnaire asking whether participants were satisfied with their relationship with their parents. HIP was diagnosed based on the criteria used in Japan. A multiple logistic regression model was applied to adjust for covariates. RESULTS: Pregnant women who were not very satisfied and not satisfied at all with the relationship with their parents, and HIP were 343 (5.5%), 74 (1.2%), and 274 (4.4%), respectively. Pregnant women who were not very satisfied with their parent-daughter relationship showed a significant positive association with HIP in the crude model (odds ratio (OR): 1.71, 95% confidence interval (CI): 1.11-2.63). When stratified by psychiatric disease history, we found a significant positive association among those without psychiatric disease history (OR: 1.77, 95% CI: 1.11-2.84), but not among those with psychiatric disease history (OR: 0.61, 95% CI: 0.16-2.28). CONCLUSIONS: Poor parent-daughter relationship was associated with the risk of HIP among pregnant women without psychiatric disease history, suggesting that this simple question could be used to estimate the risk of HIP when it was challenging to inquire directly about ACEs. Further research is needed to elucidate the mechanism of the association.

BACKGROUND: Metabolic and bariatric surgery (MBS) has been established to provide long-term weight loss in severe obesity. In this study, we investigated the factors that affect post-operative weight loss, with a particular focus on changes in eating behaviors. METHODS: Time-course changes in body weight and eating behaviors were examined in 49 Japanese patients who underwent laparoscopic sleeve gastrectomy from the first visit to 12 months after surgery. Each eating behavior was evaluated via the questionnaire of the Japan Society for the Study of Obesity. RESULTS: Pre-operative weight reduction mediated by dietary and lifestyle interventions showed significant positive correlations with weight loss outcomes at 12 months after surgery. We observed significant decreases in scores for most of the eating behaviors 12 months after surgery. However, "emotional eating behavior" scores declined temporarily in the early post-operative period of one month but thereafter returned to the pre-operative level at 12 months. Furthermore, increases in the scores for "emotional eating behavior" and "sense of hunger" from 1 to 12 months post-operatively were significantly associated with poor weight loss. CONCLUSIONS: Our results demonstrate the beneficial effects of MBS on obesity-related eating behaviors, as well as highlighting "emotional eating behavior" as requiring particular attention.

Backgrounds: A history of childhood abuse and subsequent poor relationship with parents in adulthood among pregnant women is a known risk factor for postpartum depression (PPD). Although parent-daughter relationship can change during pregnancy, little is known whether the trajectories have an impact on PPD. The aim of this study is to examine whether trajectories of parent-daughter relationship during pregnancy are associated with PPD in Japanese mothers. Methods: In a hospital-based prospective cohort study conducted in Japan, 4,772 women were followed from their first visit to their 1-month postpartum check-up (follow-up rate: 77.4%). Parent-daughter relationship was assessed whether participants were satisfied with their parents at first visit and after delivery. We defined four parent-daughter relationship trajectory categories: consistently satisfied, improving, deteriorating, and consistently unsatisfied. PPD was assessed by the Edinburgh Postnatal Depression Scale. Logistic regression model was applied to adjust covariates. Results: There were 129 (2.7%), 122 (2.6%), and 181 (3.8%) cases of improving, deteriorating, and consistently unsatisfied relationship, respectively. Compared to the group that was consistently satisfied, pregnant women of the deteriorating and consistently unsatisfied group showed 2.81 (95% CI: 1.73-4.55) and 2.39 (95% CI: 1.58-3.62) times, respectively, more likely to show PPD after adjustment for confounders. Conclusion: Women who felt that their relationship with parents "deteriorated" or was "consistently unsatisfactory" during pregnancy showed significant risk of PPD. Paying attention to the pregnant women's feelings about the relationship with their parents and promoting positive change may help predict and prevent PPD.
RESUMEN
This study aimed to evaluate the changes in quadriceps femoris muscle thickness during the pregnancy and postpartum periods and to elucidate the effect of bed rest for threatened preterm labor on muscle thickness. In 26 women with normal pregnancy, quadriceps femoris thickness was measured at 11-13, 26, 30, and 35 weeks' gestation, and at 3-5 days and 1 month postpartum using ultrasonography. In 15 pregnant women treated with bed rest for threatened premature labor, quadriceps femoris thickness was measured at 30 and 35 weeks' gestation and postpartum. In women with normal pregnancy, quadriceps femoris thickness increased, peaking at 35 weeks' gestation, followed by a postpartum decrease. In women on bed rest, quadriceps femoris thickness showed no significant change during the pregnancy and postpartum periods, and the muscle was significantly thinner at 35 weeks' gestation than that in women with normal pregnancy. In conclusion, a significant increase in quadriceps femoris muscle thickness during normal pregnancy was found using ultrasonography. Meanwhile, in pregnant women on bed rest treatment, the quadriceps femoris was significantly thinner in the late third trimester than that in normal pregnant women. Prolonged bed rest can affect normal changes in the quadriceps femoris muscle thickness during the pregnancy and postpartum periods.

BACKGROUND: Fatty acids increase ATP-binding cassette ABC transporter A12 (ABCA12) levels via an increase in peroxisome proliferator-activated receptor ß/δ (PPAR ß/δ). Promoting lipid transport to lamellar granules has been suggested to improve epidermal barrier function in patients with dry skin. OBJECTIVE: We investigated whether mevalonolactone (MVL) produced by Saccharomycopsis fibuligera improves dry skin by promoting ABCA12 expression and the amount of free fatty acids in epidermal keratinocytes. METHODS: We examined whether MVL increases ABCA12 mRNA and protein levels and the amount of Nile red-positive lipids in cultured epidermal keratinocytes and in a three-dimensional epidermal model by cell staining. Promotion of fatty acid production by MVL was analyzed by liquid chromatography-mass spectrometry. We also evaluated whether MVL addition increases PPAR ß/δ mRNA expression in cultured keratinocytes. Based on the results, a randomized controlled trial was conducted in which milky lotions containing MVL and placebo were applied to dry facial skin of healthy female volunteers in winter. RESULTS: MVL increased ABCA12 mRNA and protein levels and lamellar granule number and size. Fatty acid analysis revealed that MVL elevated myristic acid, palmitic acid, and palmitoleic acid levels as well as PPAR ß/δ mRNA expression. In human tests, milky lotions containing MVL were shown to significantly improve transepidermal water loss (TEWL) in the stratum corneum compared to placebo. CONCLUSION: The results suggest that MVL increases fatty acid uptake and ABCA12, promotes fatty acid transport to lamellar granules, and improves epidermal barrier function in dry skin through increased expression of PPAR ß/δ.

Objectives: Weight loss improves the liver pathophysiological status of nonalcoholic fatty liver disease (NAFLD) patients. However, there are few studies that investigate the accurate relationships between nutritional intake and disease progression in NAFLD patients. Methods: A total of 37 biopsy-confirmed NAFLD patients were enrolled in this study. Clinical and nutritional control data of 5074 persons were obtained from the National Institute of Health and Nutrition. Each NAFLD subject recorded dietary intake for seven consecutive days using a dietary questionnaire and photographs of each meal. A dietitian analyzed and quantified the nutritional data in each patient. We further analyzed the nutritional intake of NAFLD patients in three groups according to the following criteria: (1) liver fibrosis degree (advanced, early), (2) gender (male, female), and (3) body mass index (BMI) (high, low). Results: Excesses or deficiencies of multiple nutrients were found in NAFLD patients compared with control subjects. In addition, there were variations in nutritional intake. (1) The intake of vitamins A, B6, and E, pantothenic acid, soluble dietary fiber, and salt was lower in the advanced fibrosis group than in the early fibrosis group. (2) Fat intake was higher in male patients, and dietary fiber intake was lower in both male and female patients compared with control subjects. (3) Saturated fatty acid intake was higher, and copper and vitamin E intakes were lower in patients with high BMI than with low BMI. Conclusions: Our study demonstrates that differences were found in some nutrient intake of NAFLD patients and controls and according to the severity of the conditions (liver fibrosis degree, BMI).

Japanese pharmaceutical cosmetics, often referred to as quasi-drugs, contain skin-lightening active ingredients formulated to prevent sun-induced pigment spots and freckles. Their mechanisms of action include suppressing melanin production in melanocytes and promoting epidermal growth to eliminate melanin more rapidly. For example, arbutin and rucinol are representative skin-lightening active ingredients that inhibit melanin production, and disodium adenosine monophosphate and dexpanthenol are skin-lightening active ingredients that inhibit melanin accumulation in the epidermis. In contrast, oral administration of vitamin C and tranexamic acid in pharmaceutical products can lighten freckles and melasma, and these products are more effective than quasi-drugs. On the basis of their clinical effectiveness, skin-lightening active ingredients can be divided into four categories according to their effectiveness and adverse effects. This review discusses academic research and development regarding skin-lightening ingredients in Japan.

Intercellular lipids comprise mainly ceramides, known to enhance the barrier function of the stratum corneum. However, the activities of ceramides inside the skin have not yet been fully elucidated. Here we examined how the human ceramide mixture (HC123) functions in the dermis. We treated human skin fibroblasts with HC123-expressed fibroblast growth factor (FGF), transforming growth factor-ß (TGF-ß), collagen I, and fibrillin. We found that HC123 promoted the formation of collagen fibers and microfibrils (fibrillin) which affect the elasticity of the skin. We also confirmed that the gene expression of collagen and fibrillin is promoted via TGF-ß and FGF2, respectively. We then investigated the permeability of HC123 for external use, in pursuit of evidence that HC123 may exert an anti-aging effect by penetrating into the dermis, activating fibroblasts, and promoting the production of collagen fibers and elastin-related microfibrils.

OBJECTIVE: To develop and validate the Social Life Impact for Mother (SLIM) scale to identify mothers in Japan who need social support postpartum. METHODS: Hospital-based prospective study was implemented nationwide in Japan. A total of 7462 pregnant women completed the SLIM scale in their first trimester, and postpartum social problems (postpartum depression and bonding disorders) were assessed at 1 month after delivery (N = 5768, follow-up rate 77.3%). Multivariate logistic regression was applied to investigate the association between SLIM scale and postpartum social problems. RESULTS: The SLIM scale is made up of nine risk factors for postpartum social problems, including relationship problems, lower financial status, and lack of social support. The SLIM scale predicted postpartum social problems with moderate accuracy (area under the curve 0.63, 95% confidence interval 0.60-0.65). Further stratification by local clinic and tertiary hospital did not affect the estimates. CONCLUSION: The SLIM scale at prenatal check-up may be useful for obstetricians to detect mothers with postpartum social problems. Further intervention studies using the SLIM score are warranted.

We reported that raspberry ketone (RK) is produced from rhododendrol (RD) in excised mouse skin. We confirmed that RK is also produced from RD in human skin homogenates. We also observed more conversion of RD to RK when the oxidized form of nicotinamide adenine dinucleotide (NAD+), a coenzyme of alcohol dehydrogenase (ADH), was added to human skin homogenates. Chiral column analysis of the consumption of RD enantiomers in human skin homogenates also showed that more of the R enantiomers of RD remained than the S enantiomers of RD. This suggests that the S-enantiomer of RD is more easily oxidized in human skin. We confirmed that RD is partially metabolized to RK in human skin, thus suggesting that ADH in the skin may be the main cause of the appearance of this oxidation product.
RESUMEN
Many transgender men receive testosterone therapy to achieve virilization. The therapy is often mistaken for having a contraceptive effect because it causes amenorrhea. However, some treated patients become pregnant, which is not well known. A 25-year-old transgender man who had received testosterone for 3 years had an unplanned pregnancy during discontinuation of treatment. He was unaware of his pregnancy, resumed testosterone, and continued treatment until pregnancy was confirmed. His female child was exposed to androgens during the fetal period; thus, careful, long-term observation was required. He developed insomnia and depression during the postpartum, and giving birth made it difficult for him to change his family register to male. Transgender men can become pregnant through sexual intercourse with biological men, even during hormone replacement therapy, so correct contraception is necessary to avoid unwanted pregnancies. Transgender sex education is important to increase awareness of this issue among individuals and medical professionals.
