RESUMEN
We report a successful case for the clinical efficacy of the endometrial receptivity array (ERA) test for a 32-year-old female patient with refractory infertility. After our careful treatment, the patient gave birth to a male baby (3390 g) in November 2021. To our knowledge, though the clinical efficacy of the ERA test is controversial until March 2024, we think that the age of the patients, the number of IVF cycles, and the racial differences may have an impact on the clinical efficacy of the ERA test.
RESUMEN
We report the first case of successful genetic counseling for an infertile couple with premature chromatid separation (PCS) syndrome. After our careful genetic counseling, the couple decided to continue infertility treatment. As a result, they gave birth to a baby (girl: 2,930 g) by caesarean section in May 2018. To our knowledge, there have not been any published reports regarding genetic counseling for an infertile couple with PCS after PubMed, EMBASE, and Web of Science searches until March 2024.
RESUMEN
Alzheimer's disease (AD) is a neurodegenerative disease that commonly causes dementia. Identifying biomarkers for the early detection of AD is an emerging need, as brain dysfunction begins two decades before the onset of clinical symptoms. To this end, we reanalyzed untargeted metabolomic mass spectrometry data from 905 patients enrolled in the AD Neuroimaging Initiative (ADNI) cohort using MS-DIAL, with 1,304,633 spectra of 39,108 unique biomolecules. Metabolic profiles of 93 hydrophilic metabolites were determined. Additionally, we integrated targeted lipidomic data (4873 samples from 1524 patients) to explore candidate biomarkers for predicting progressive mild cognitive impairment (pMCI) in patients diagnosed with AD within two years using the baseline metabolome. Patients with lower ergothioneine levels had a 12% higher rate of AD progression with the significance of P = 0.012 (Wald test). Furthermore, an increase in ganglioside (GM3) and decrease in plasmalogen lipids, many of which are associated with apolipoprotein E polymorphism, were confirmed in AD patients, and the higher levels of lysophosphatidylcholine (18:1) and GM3 d18:1/20:0 showed 19% and 17% higher rates of AD progression, respectively (Wald test: P = 3.9 × 10-8 and 4.3 × 10-7). Palmitoleamide, oleamide, diacylglycerols, and ether lipids were also identified as significantly altered metabolites at baseline in patients with pMCI. The integrated analysis of metabolites and genomics data showed that combining information on metabolites and genotypes enhances the predictive performance of AD progression, suggesting that metabolomics is essential to complement genomic data. In conclusion, the reanalysis of multiomics data provides new insights to detect early development of AD pathology and to partially understand metabolic changes in age-related onset of AD.

OBJECTIVES: Nuts are nutrient-dense foods rich in unsaturated fatty acids, protein, dietary fiber, vitamins, and minerals. The present prebirth cohort study examined the association between maternal nut intake during pregnancy and the risk of childhood behavioral problems in 5-year-old Japanese children. METHODS: Study subjects were 1199 mother-child pairs. Dietary intake was assessed using a diet history questionnaire. Emotional problems, conduct problems, hyperactivity problems, peer problems, and low prosocial behavior were assessed using the parent-reported version of the Strengths and Difficulties Questionnaire. Adjustments were made for a priori-selected nondietary confounders and potentially related dietary factors. RESULTS: Compared with mothers who had not eaten nuts during pregnancy, mothers who had eaten nuts had a significantly reduced risk of peer problems in children; the adjusted odds ratio was 0.64 (95% confidence interval: 0.42-0.97). There were no measurable associations between maternal consumption of nuts during pregnancy and the risk of childhood emotional problems, conduct problems, hyperactivity problems, and low prosocial behavior. CONCLUSIONS: Maternal consumption of nuts during pregnancy may be associated with a decreased risk of peer problems in 5-year-old children.

Triacylglycerols (TAGs) are a major fat component in human milk. Since gastric lipase produces 1,2-diacylglycerol from TAGs, we focused on the bioactivity of human milk-derived diacylglycerols in stomach cells. Ghrelin is produced in the stomach and acts as an important regulator of growth hormone secretion and energy homeostasis. In this study, we showed that 1-oleoyl-2-palmitoylglycerol (OP) increased ghrelin secretion, whereas 1,3-dioleoyl-2-palmitoylglycerol (OPO), a major component of human milk TAGs, did not increase ghrelin secretion in the ghrelin-secreting cell line, MGN3-1. Therefore, diacylglycerol OP may directly contribute to the regulation of ghrelin secretion. We also found that 2-palmitoylglycerol and 1- and 2-oleoylglycerol increased ghrelin secretion. Finally, we demonstrated that intracellular cAMP levels and preproghrelin and ghrelin O-acyl transferase expression levels were enhanced by OP treatment in MGN3-1 cells. This may represent an example of a novel mother-infant interaction mediated by fat components derived from human breast milk.

Several bacterial strains, including probiotic strains, have undergone evaluations for their safety and potential beneficial health effects. Some of these strains have been introduced into various markets, including that for infant products. However, certain probiotic strains have been linked to serious infections in infants, such as septicemia and meningitis. Given this, it is crucial to assess the safety of each probiotic strain, including those of Bifidobacterium, which is a common genus of probiotics. One such strain, Bifidobacterium bifidum OLB6378 (NITE BP-31), referred to as OLB6378 hereafter, has been selected for use in infants. To determine its genotoxicity and general toxicity potential, a heat-treated OLB6378 concentrate was subjected to various tests, including the bacterial reverse mutation test, in vitro chromosome aberration test, in vivo micronucleus test, and single- and 90-day oral gavage toxicity studies in rats. No significant differences were observed compared with negative controls in any of genotoxicity tests. The single-dose toxicity study employed dose levels of 560, 1,693, and 5,092â mg/kg, representing the total solid contents of culture concentrates containing OLB6378 (equivalent to 8.1 × 1011, 2.4 × 1012, and 7.4 × 1012 cells/kg of Bifidobacterium, respectively). In the 90-day toxicity study, dose levels of 280, 853, and 2,546â mg/kg/day were used (equivalent to 4.0 × 1011, 1.2 × 1012, and 3.7 × 1012 cells/kg/day, respectively). Importantly, the heat-treated OLB6378 concentrate did not induce any signs of toxicity in any of the conducted toxicity studies. In conclusion, the heat-treated OLB6378 concentrate exhibited no genotoxicity potential, and the no-observed-adverse-effect level in the 90-day toxicity study was determined to be 2,546â mg/kg/day (equivalent to 3.7 × 1012 cells/kg/day). This suggests that heat-treated OLB6378 can be safely utilized as a food source.
RESUMEN
Introduction Photodynamic therapy (PDT) is a salvage treatment for local failure after chemoradiotherapy for esophageal cancer. Salvage PDT is the treatment available for vulnerable patients with various comorbidities at risk of salvage esophagectomy. This study assessed the impact of the Charlson comorbidity index (CCI) on the outcomes of salvage PDT using talaporfin sodium (TS) for esophageal cancer. Metohds Consecutive patients with esophageal cancer who underwent salvage TS-PDT from 2016 to 2022 were included in this retrospective study. We investigated the local complete response (L-CR), progression-free survival (PFS) and overall survival (OS) and evaluated the relationship between the CCI and therapeutic efficacy. Results In total, 25 patients were enrolled in this study. Overall, 12 patients (48%) achieved an L-CR, and the 2-year PFS and OS rates were 24.9% and 59.4%, respectively. In a multivariate analysis, a CCI ≥1 (p=0.041) and deeper invasion (p=0.048) were found to be significant independent risk factors for not achieving an L-CR. To evaluate the efficacy associated with comorbidities, we divided the patients into the CCI=0 group (n=11) and the CCI ≥1 group (n=14). The rate of an L-CR (p=0.035) and the 2-year PFS (p=0.029) and OS (p=0.018) rates in the CCI ≥1 group were significantly lower than those in the CCI=0 group. Conclusion This study found that the CCI was negatively associated with the efficacy of salvage TS-PDT for esophageal cancer.

The occurrence of anti-Ku antibody-positive idiopathic inflammatory myopathy (IIM) in pediatric patients is rare, and therefore, the clinical phenotypes of this disease in such patients remain obscure. We herein report two cases of Japanese female pediatric patients with anti-Ku antibody-positive IIM. One case was unique in that it was complicated by pericardial effusion. Another patient had severe and refractory myositis with immune-mediated necrotizing myopathy. In addition, we reviewed literatures involving a total of 11 pediatric patients with anti-Ku antibody-positive IIM. The median age of the patients was 11 years, and most of them were girls. Skin rash, including erythematous nodules, malar rash, multiple brownish plaques, butterfly rash, heliotrope rash, periorbital edema, and Gottron's papules, was observed in 54.5% of the patients, scleroderma in 81.8%, and skin ulcer in 18.2%. Their serum creatine kinase level ranged from 504 to 10,840 IU/L. Furthermore, joint involvement was observed in 91% of the patients, interstitial lung disease in 18.2%, and esophageal involvement in 9.1%. All patients were treated with corticosteroids in combination with immunosuppressants. Pediatric patients with anti-Ku antibody-positive IIM had unique characteristics compared to adult patients. Skin manifestations, joint involvement and elevation of serum CK levels were more common in children than in adults. In contrast, ILD and esophageal involvement were less common in children than in adults. Although pediatric cases of anti-Ku antibody-positive IIM are rare, patients with IIM need to be tested for the presence of anti-Ku antibodies.

Breast milk contains constituents, such as 1,3-dioleoyl-2-palmitoylglycerol (OPO), that are beneficial for infants. Herein, we hypothesized that 2-palmitoyl glycerol (2-PG), a derivative of OPO, is advantageous to infants' development. Gamma aminobutyric acid (GABA) is a major neurotransmitter involved in neural development. Although GABA is generally known to be produced in neurons, astrocytes can also produce it in immature brains. In this study, we used expression analysis techniques to show that 2-PG upregulates the mRNA and protein expression of glutamate decarboxylases (GAD1 and GAD2) in normal human fetal-derived astrocytes. Our data suggest that 2-PG promotes GABA synthesis in astrocytes, which may contribute to brain development because GABA is involved in neural development in the developing brain. This may help to elucidate the mechanism by which breast milk affects infant brain development.

The anti-rotavirus components in breast milk and infant formulas play an important role in the prevention of rotavirus infection. The present study examined whether the levels of phospholipids and bovine lactadherin, which are the major components and proteins of the milk fat globule membrane complex, are useful indices of the anti-rotavirus activity of dairy ingredients used in infant formulas. We compared the anti-rotavirus activity of 2 types of dairy ingredients enriched in the milk fat globule membrane complex: high-fat whey protein concentrate (high-fat WPC) and butter milk powder (BMP), using 50% inhibition concentration (IC50) and linear inhibition activity to determine levels of solid contents, total proteins, phospholipids, and bovine lactadherin. Here, we developed a quantification method using full-length isotope-labeled proteins to measure bovine lactadherin levels in these dairy ingredients. The evaluation of anti-rotavirus activity showed that the difference in IC50 was the smallest when the 2 dairy ingredients were compared at the bovine lactadherin level, among other indices in this study. Additionally, no significant difference was observed between the inhibition linearity of 2 dairy ingredients when evaluating only bovine lactadherin levels. These results indicated that the level of bovine lactadherin was more strongly associated with anti-rotavirus activity than the level of phospholipids. Our results suggest that bovine lactadherin levels can be used to estimate the anti-rotavirus activity of dairy ingredients and can be a criterion used in selecting ingredients for infant formulas.

Background and Objectives: In transpapillary biliary drainage, metal stents (MSs) exhibit a lower incidence of a biliary obstruction than plastic stents (PSs). However, few studies have compared recurrent biliary obstruction (RBO) when MSs and PSs are used in EUS-guided hepaticogastrostomy (EUS-HGS) and choledochoduodenostomy (EUS-CDS). We retrospectively evaluated the RBO for both stents in each procedure. Patients and Methods: : Between November 2012 and December 2020, 85 and 53 patients who underwent EUS-HGS and EUS-CDS for unresectable malignant biliary obstruction, respectively, were enrolled. Factors associated with RBO were assessed. Clinical outcomes were compared between the MS and PS groups using propensity score matching. Results: : The clinical success rate and procedure-related adverse events were similar in the MS and PS groups. Multivariate analysis identified the use of PS as a factor associated with RBO (EUS-HGS, P = 0.03; EUS-CDS, P = 0.02). After matching, the median time to RBO in EUS-HGS (MS: 313; PS: 125 days; P = 0.01) in the MS group was longer than that in the PS group. The cumulative incidence of RBO at 1, 3, and 6 months in the MS group was significantly lower than that in the PS group for EUS-HGS (MS: 4.0%, 8.2%, and 8.2%; PS: 12.4%, 24.9%, and 39.5%, respectively, P = 0.01). Conclusions: : MS exhibited a lower rate of RBO than PS for EUS-HGS and EUS-CDS.
RESUMEN
BACKGROUND/PURPOSE: The benefits of anti-reflux metal stents, used for treating biliary obstruction in patients receiving neoadjuvant chemotherapy (NAC) for pancreatic cancer, are yet unknown. Herein, the safety and efficacy of the novel duckbill-type anti-reflux metal stent (D-ARMS) were prospectively evaluated for biliary drainage. Additionally, the incidence of recurrent biliary obstruction (RBO) after placement of D-ARMS vs conventional covered self-expandable metal stents (CCSEMSs) was retrospectively compared. METHODS: Patients who received D-ARMS (n = 33) for treatment of distal biliary obstruction before NAC between September 2019 and January 2021 and those that received CCSEMSs (n = 38) between January 2013 and August 2019 were included in the historical control group. Technical and clinical successes, rate of RBO, and cumulative incidence of RBO were compared between the two groups. RESULTS: The technical success rate was 100% for both the D-ARMS and CCSEMS groups, and the clinical success rate were not significantly different (93.9% and 89.5%, respectively; P = .68). In the multivariate analysis, D-ARMS was identified as the independent factor for cumulative incidence of RBO (P = .03). The cumulative incidence of RBO was significantly lower in the D-ARMS group than that in the CCSEMS group (P = .04). CONCLUSIONS: D-ARMS is safe and effective for patients receiving NAC.

(1) Background: Breast milk is the only source of nutrition for breastfed infants, but few studies have examined the relationship between breast milk micronutrients and infant neurodevelopmental outcome in exclusively breastfed infants. The aim of this study was to characterize the association between nicotinamide adenine dinucleotide (NAD)-related compounds in the breast milk of Japanese subjects and infant neurodevelopmental outcome. (2) Methods: A total of 150 mother-child pairs were randomly selected from the three-generation cohort of the Tohoku Medical Megabank in Japan. Infants were exclusively breastfed for up to 6 months. Breast milk was collected at 1 month postpartum, and the quantity of NAD-related substances in the breast milk was quantified. The mothers also completed developmental questionnaires at 6, 12, and 24 months. The relationship between the concentration of NAD-related substances in breast milk and developmental indicators was evaluated via ordinal logistic regression analysis. (3) Results: Nicotinamide mononucleotide (NMN) was quantified as the major NAD precursor in breast milk. The median amount of NMN in the breast milk was 9.2 µM. The NMN concentration in breast milk was the only NAD-related substance in breast milk that showed a significant positive correlation with neurodevelopmental outcome in infants at 24 months. (4) Conclusions: The results suggest that NMN in human milk may be an important nutrient for early childhood development.

Foreign body granuloma(FBG)is a granuloma that occurs due to chronic inflammation caused by various residual foreign objects. In the field of gastrointestinal surgery, intraperitoneal foreign body granulomas(IPFBGs)are often caused by sutures materials or residual gauzes, but those caused by food residue are extremely rare. We present an IPFBG case of food residue caused by anastomotic leakage, which was difficult to be distinguished from peritoneal dissemination. The patient is a 74- year-old male. Anastomotic leakage occurred following low anterior resection for rectal cancer, peritoneal drainage and ileostomy were performed. 1.5 years after rectal resection, liver metastasis was diagnosed by CT and peritoneal dissemination was diagnosed by PET-CT. Both lesions were resected at the same time. The pathological findings were liver metastasis and FBG. It was presumed to be an FBG formed by food residue left behind after anastomotic leakage. It has reported that FBG caused by residual gauzes were shown a ring-shaped uptake by PET-CT, but that was not observed in our case. In addition, since a nodule suspected of liver metastasis was observed simultaneously, we considered no differential diagnosis other than peritoneal dissemination. IPFBG resembling peritoneal dissemination, occurred after anastomotic leakage. A food residue can cause IPFBG, it is necessary to consider IPFBG in decision making treatment strategy for peritoneal nodule.

BACKGROUND: Exosomes are nanosized extracellular vesicles, that play important roles in intercellular immune regulation. They have potential therapeutic utility for neonatal diseases including necrotizing enterocolitis. Breast-milk-derived exosomes have recently shown beneficial effects on intestinal damage in vitro and in vivo. However, the chronological change in breast-milk-derived exosome concentrations after delivery are unclear. METHODS: In this prospective study, we enrolled 17 mothers who delivered premature infants admitted to a neonatal intensive care unit in Japan. We measured the consecutive concentrations of breast-milk-derived exosomes in the mothers for 48 weeks after delivery. RESULTS: The median concentration of breast-milk-derived exosomes was 1.62 × 108 particles/ml in colostrum, showing a significant decrease after 2 weeks (P < 0.01). There was no association between the exosome concentration in colostrum and maternal perinatal factors including parity, mode of delivery, maternal age, and gestational age at delivery. CONCLUSIONS: We concluded that breast-milk-derived exosomes were the richest in colostrum. Our basic data regarding breast-milk-derived exosomes are expected to aid in the clinical application of exosomes for treating neonatal diseases.

Milk is a good source of fats, minerals, and vitamins. The present prebirth cohort study examined the association between maternal dairy product intake during pregnancy and the risk of childhood behavioral problems in 5-year-old Japanese children. Study subjects were 1199 mother-child pairs. Dietary intake was assessed using a diet history questionnaire. Emotional problems, conduct problems, hyperactivity problems, peer problems, and low prosocial behavior were assessed using the parent-reported version of the Strengths and Difficulties Questionnaire. Adjustments were made for a priori selected non-dietary confounders and potentially related dietary factors. A significant inverse exposure-response association was observed between maternal total dairy intake during pregnancy and the risk of childhood emotional problems (adjusted odds ratio [OR] between extreme quartiles, 0.62; 95% confidence interval [CI]: 0.36-1.03, p for trend, 0.04). The greater maternal consumption of cow's milk, but not yogurt or cheese, during pregnancy was independently related to a reduced risk of emotional problems in children (adjusted OR between extreme quartiles, 0.41; 95% CI: 0.23-0.70, p for trend, 0.003). Higher maternal consumption levels of total dairy products, especially cow's milk, during pregnancy may be associated with a decreased risk of emotional problems in 5-year-old children.

PROBLEM: Regulatory T cells (Tregs) play important roles in diseases occurring in women of reproductive age and pregnancy. Tregs are functionally heterogeneous and can be divided into activated Tregs (aTregs), resting Tregs (rTregs), and non-suppressive Tregs (non-Tregs). The purpose of this study is to investigate the change of Treg subpopulations during the menstrual cycle and early pregnancy. METHOD OF STUDY: Two groups of women were enrolled: healthy women aged 20 to 39 years with normal menstrual cycles and patients scheduled to undergo frozen-thawed blastocyst transfer (FT-BT) (subfertile women). Peripheral blood samples were collected at day 5 of the onset of menstruation (follicular phase), 0-2 days after luteinizing hormone (LH) surge (periovulatory phase), and 7-11 days after LH surge (luteal phase) from 20 healthy women. From 23 subfertile women, samples were collected at day 5 (the day of BT) and day 14 (the day of pregnancy testing) of progestogen administration during FT-BT cycle and 9 weeks of gestation if the patient got pregnant. The proportion of total Treg and its subpopulations among CD4+ T cells was analyzed. RESULTS: TTreg and aTreg proportion expanded during periovulatory phase (p < .01) and after pregnancy (p < .05 for tTreg and p < .01 for aTreg). rTreg proportion was significantly high during periovulatory phase (p < .01) and during luteal phase (p < .01). Non-Tregs showed no significant change. CONCLUSIONS: RTregs and aTregs, especially in luteal phase and after getting pregnant, showed significant changes and may play important roles in women of reproductive age.

In past reports, the incidence of gastric perforation accounts for 0.08 to 3.6% of all gastric cancers, and the proportion of perforated gastric cancer(PGC)in gastric perforations is 26 to 32%. In the treatment of PGC, critical care for peritonitis, diagnosis of gastric cancer and curability for gastric cancer are required simultaneously, so it is not easy to decide the treatment strategies. Therefore, for the purpose to consider treatment strategies for PGC, we conducted a clinicopathological study on PGC in our hospital for the past 12 years. There were 22 cases of PGC, and we analyzed clinicopathologically 19 cases excluding perforation during endoscopic resection and perforation during chemotherapy. The R0 surgery group tended to have a good prognosis even in PGC cases, and there was surgery-related death in the one-stage gastrectomy group. So it was considered desirable to perform radical surgery after the general condition was stable by the treatment of peritonitis was given priority in the PGC.

BACKGROUND: Infants ≤90 days old can exhibit non-specific signs of infection, even in cases of serious bacterial infection (SBI). METHODS: This prospective study included infants aged ≤90 days hospitalized for fever from June 2017 to August 2019. Nasopharyngeal swabs were tested using multiplex real-time polymerase chain reaction (PCR) tests and 16S ribosomal RNA analysis of whole blood to determine causative microorganisms. Data pertaining to inflammatory markers, maximum body temperature (BT), and respiratory symptoms of infants and their cohabiting families were collected at admission. RESULTS: A total of 110 infants were enrolled (age range, 9-90 days), 17 (15.5%) of whom presented with SBIs. White blood cell (WBC) count and absolute neutrophil count (ANC) were significantly higher in patients with SBIs than in those without, although maximum BT did not significantly differ between the SBI and non-SBI groups (n = 93). One or more viruses were detected in 82 infants (74.5%). Viruses were detected more frequently in infants with respiratory symptoms than in those without respiratory symptoms (P = 0.038), and patients with SBIs experienced significantly less respiratory symptoms than those without SBIs (P = 0.049). Moreover, viruses were more often detected in infants from cohabiting families with respiratory symptoms than in those whose family members did not exhibit respiratory symptoms (P = 0.0018). CONCLUSION: White blood cell count, and ANC were significantly higher, and respiratory symptoms were less in infants ≤90 days old with SBIs than in those without SBIs. Microorganisms from nasopharyngeal by multiplex real-time PCR swabs could not be judged as SBI or non-SBI.

Bifidobacterium bifidum OLB6378 (OLB6378) was selected as a strain that enhances the production of secretory immunoglobulin A (IgA) in vitro. This ability of non-live OLB6378 has been shown by a clinical trial in preterm infants. In the present study, we examined whether non-live OLB6378 also enhances the production of secretory IgA, even in full-term infants. One hundred full-term infants were allocated to receive formula with (BbF group, 49 infants) or without non-live OLB6378 (PF group, 51 infants). Breastfeeding was prioritised, so infant formula was used for infants with breastfeeding difficulties. The intervention was initiated by five days of age. The faecal IgA concentration and OLB6378 level were determined at one, two, four, and eight weeks of age. Faecal IgA in the BbF group (1.04 ± 0.47â mg/g of faeces, n=45) was significantly higher than that in the PF group (0.85 ± 0.42â mg/g of faeces, n=49) at four weeks of age (p=0.047). OLB6378 was not detected in faeces at any age. This indicated that production of secretory IgA in full-term infants may also be enhanced by non-live OLB6378 intake.
