RESUMO
Precise vaccination data is essential to accurately estimate the effectiveness of the human papillomavirus (HPV) vaccine against HPV-related cancers. In Japan, the number of subsidized HPV vaccinations can be tracked through registries, but the number of self-funded vaccinations has not been tracked. The number of individuals who chose to receive the vaccine at their own expense, despite being ineligible for public subsidies due to their age, is unknown and has been nominally considered to be zero. Our aim is to produce a more accurate estimate of this number using recently released proprietary data. First, we estimated the total number of self-funded HPV vaccinations occurring from 2010 to 2012 using public data from the Ministry of Health, Labour and Welfare and our previously reported data on the number of HPV vaccinations eligible for public subsidy. Second, using proprietary data from the vaccine manufacturer, we calculated the distribution of self-funded vaccination shots by age. Finally, we combined these data to estimate the number of self-funded HPV vaccinations by birth fiscal year (FY) relative to a yearly reference population. We found that 78,264 individuals born in FY1993 and 58,190 born in FY1992 self-funded their vaccinations, representing 13.6% and 10.0% of the reference population, respectively. Additionally, we found that 5%-10% of individuals born from FY1986 to FY1991 self-funded their vaccinations. Our study revealed for the first time that a certain number of individuals from the "HPV unvaccinated generation," ineligible for subsidies due to age restrictions, chose to self-fund their vaccinations.
RESUMO
OBJECTIVE: To assess the association between gestational age at birth and the risk of growth failure and respiratory symptoms at 3 years of age. DESIGN: Cohort study using the Japan Environment and Children's Study database. PATIENTS: A total of 86 158 singleton infants born without physical abnormalities at 32-41 weeks of gestation were enrolled between January 2011 and March 2014. MAIN OUTCOME MEASURES: Growth failure (weight <10th percentile and height <10th percentile) and respiratory symptoms (asthma and wheezing) at 3 years of age. METHODS: Logistic regression analysis was used to evaluate the risk of growth failure and respiratory symptoms in the moderately preterm, late preterm and early term groups compared with the full-term group after adjusting for socioeconomic and perinatal factors. Multiple imputation was used to reduce the attrition bias related to missing data. RESULTS: The respective adjusted ORs (95% CI) of growth failure and respiratory symptoms for the moderate preterm, late preterm and early term groups compared with the full-term group were as follows: weight <10th percentile, 2.29 (1.48-3.54), 1.43 (1.24-1.71) and 1.20 (1.12-1.28); height <10th percentile, 2.34 (1.59-3.45), 1.42 (1.25-1.60) and 1.15 (1.09-1.22); asthma, 1.63 (1.06-2.50), 1.21 (1.04-1.41) and 1.16 (1.09-1.23); and wheezing, 1.39 (1.02-1.90), 1.37 (1.25-1.51) and 1.11 (1.06-1.17). CONCLUSION: Moderate preterm, late preterm and early term births were associated with a higher risk of growth failure and respiratory symptoms at 3 years of age than full-term births, with an inverse dose-response pattern.
RESUMO
AIM AND OBJECTIVE: Our recent report showed that soluble T-cadherin promotes pancreatic beta-cell proliferation. However, how and where the secretion of soluble T-cadherin is regulated remain unclear. METHODS AND RESULTS: Soluble T-cadherin levels significantly increased in leptin receptor-deficient db/db mice with hypoinsulinaemia or in wild-type mice treated with insulin receptor blockade by S961. Similar results were observed in human subjects; Diabetic ketoacidosis patients at the time of hospitalization had increased plasma soluble T-cadherin levels, which decreased after insulin infusion therapy. Patients with recurrent ovarian cancer who were administered a phosphatidylinositol-3 kinase (PI3K)-alpha inhibitor (a new anticancer drug) had increased plasma soluble T-cadherin and plasma C-peptide levels. Endothelial cell-specific T-cadherin knockout mice, but not skeletal muscle- or cardiac muscle-specific T-cadherin knockout mice, showed a 26 % reduction in plasma soluble T-cadherin levels and a significant increase in blood glucose levels in streptozocin-induced diabetes. The secretion of soluble T-cadherin from human endothelial cells was approximately 20 % decreased by insulin and this decrease was canceled by blockade of insulin receptor/Akt signalling, not Erk signalling. CONCLUSION: We conclude that insulin regulates soluble T-cadherin levels and soluble T-cadherin secretion from endothelial cells is positively regulated by insulin/insulin receptor/Akt signalling.
RESUMO
Importance: The Ministry of Health, Labour, and Welfare (MHLW) of Japan aggregates human papillomavirus (HPV) vaccination data across Japan for each fiscal year (FY) by age at vaccination. Birth FY (BFY)-specific vaccination coverage remains unknown. Objective: To calculate the BFY-specific vaccination coverage for each FY and the cumulative first-dose coverage for each BFY in Japan, to understand the generation-specific vaccination coverage, and to estimate the cumulative first-dose coverage of each BFY that would be achieved by FY 2028 vs World Health Organization (WHO) targets. Design, Setting, and Participants: In this cross-sectional study, MHLW-published national age-specific HPV vaccination numbers and demographic data for female individuals were used to calculate the BFY-specific first-dose coverage for each FY and the BFY-specific cumulative first-dose coverage. It was assumed that the BFYs 2007 to 2012 vaccination coverage in FY 2023 to 2028 would remain the same as the vaccination coverage of the same grade in FY 2022 to estimate the cumulative first-dose coverage that would be achieved by FY 2028. Data analysis was performed from December 2023 to January 2024. Exposure: Two MHLW policy changes were the government's suspension of proactive recommendation for HPV vaccination in June 2013 and the government's resumption of proactive recommendation for HPV vaccination in April 2022. Main Outcomes and Measures: The primary outcome was generation-specific vaccination coverage among female individuals born in BFYs 1994 to 2010 in FYs 2010 to 2022, calculated using reconfigured published data. Results: In this study of vaccination data for 9â¯414â¯620 female individuals, the generation-specific vaccination coverage was 71.96% for the vaccination generation (BFYs 1994-1999), 4.62% for the vaccine-suspension generation (BFYs 2000-2003), 16.16% for the generation that received information individually (BFYs 2004-2009), and 2.83% for the vaccine-resumed generation (BFY 2010). HPV routine vaccination coverage was extremely low in BFYs 2000 to 2010 (0.84%-25.21%) vs BFYs 1994 to 1999 (53.31%-79.47%). The cumulative first-dose coverage that was estimated to be achieved in the vaccine-resumed generation by FY 2028 plateaued at 43.16%. Conclusions and Relevance: Even after the resumption of MHLW's proactive recommendations, HPV vaccination coverage has only minimally recovered in Japan. The cumulative first-dose coverage that was estimated to be achieved in the vaccine-resumed generation by FY 2028 is below the WHO target. These findings reveal that stronger cervical cancer control measures are required, particularly for the vaccine-resumed generation, which will plateau at approximately one-half the WHO target values.

AIM: The aim of this study was to determine the level of awareness of sexual reproductive health and rights (SRHR) among the members of the Japan Society of Obstetrics and Gynecology (JSOG) and identify what the JSOG should do to address SRHR issues. METHODS: A survey questionnaire on JSOG members' awareness of SRHR and what the JSOG should address regarding SRHR was administered in 2019 and 2023. Changes in awareness and the issues that should be addressed from the first to the second survey were evaluated. RESULTS: Seven hundred twelve members responded to the first survey and 506 to the second. Response rates were 4.2% and 2.9%, respectively. There was a significant increase in the number of respondents in the second survey who were aware of sexual reproductive health (SRH) and Sustainable Development Goals (SDGs) compared with the first survey (SRH: 72.6%-86.4%; SDGs: 33.8%-86.4%). Most respondents agreed that SRHR should be promoted. In the first survey, cervical cancer was the most important issue, followed by women's right to self-determination and family planning/contraception. In the second survey, women's right to self-determination was the most important issue. Several free responses highlighted the importance of comprehensive sexuality education as a significant concern for SRHR. CONCLUSION: Between 2019 and 2023, the level of awareness of SRHR among JSOG members increased. The identification of SRHR issues that should be addressed by the JSOG was confirmed. The JSOG and individual obstetricians and gynecologists are responsible for being involved in achieving SRHR.
RESUMO
Epithelial ovarian cancer is characterized by aggressive peritoneal dissemination. Neutrophils are mobilized to peritoneal cavity in some patients with ovarian cancer dissemination, however, its pathological significance remains unknown. This study aimed to investigate the role of neutrophil extracellular traps (NETs) in ovarian cancer dissemination. We conducted a retrospective analysis of clinical data and samples from 340 patients with ovarian cancer who underwent primary surgery between 2007 and 2016 at the Osaka University Hospital. In vitro, NETs formation was induced by stimulating human peripheral neutrophils. The human ovarian cancer cell line, OVCAR8, was co-cultured with NETs. For an ovarian cancer dissemination mouse model, we performed an intraperitoneal injection of OVCAR8 cells into nude mice. The association between NETs and peritoneal dissemination was explored, and model mice were treated with the peptidylarginine deiminase 4 (PAD4) inhibitor GSK484 to assess antitumor efficacy. Neutrophilia (neutrophil count >7000/mm3) correlated with shorter survival, advanced peritoneal dissemination, elevated granulocyte colony-stimulating factor (G-CSF) levels, increased neutrophil count in ascites, and augmented NETs foci in peritoneal dissemination sites. In vitro assays revealed that G-CSF stimulated neutrophils to form NETs, promoting cancer cell adhesion. In vivo investigations revealed that G-CSF-producing tumor-bearing mice had accelerated peritoneal dissemination and poor prognosis. NETs formation was pathologically observed at the peritoneal dissemination sites. Inhibition of NETs formation by GSK484 significantly delayed peritoneal dissemination in vivo. In conclusion, G-CSF was associated with intra-abdominal NETs formation and increased peritoneal dissemination. NETs represent potential therapeutic targets for ovarian cancer, particularly in patients with neutrophilia.
RESUMO
Preterm birth is a serious pregnancy complication that affects neonatal mortality, morbidity, and long-term neurological prognosis. Predicting spontaneous preterm delivery (PTD) is important for its management. While excluding the risk of PTD is important, identifying women at high risk of PTD is imperative for medical intervention. Currently used PTD prediction parameters in clinical practice have shown high negative predictive values, but low positive predictive values. We focused on sulfated and sialylated glycocalyx changes in the uterus and vagina prior to the onset of parturition and explored the potential of electrophysiological detection of these changes as a PTD prediction parameter with a high positive predictive value. In vivo local vaginal bioelectrical impedance (VZ) was measured using two different mouse PTD models. PTD was induced in ICR mice through the subcutaneous injection of mifepristone or local intrauterine injection of lipopolysaccharide (LPS). The PTD rates were 100% and 60% post-administration of mifepristone (16-20 h, n = 4) and LPS (12-24 h, n = 20), respectively. The local VZ values (15 and 10 h after mifepristone or LPS treatment, respectively) were significantly lower in the PTD group than in the non-PTD group. Receiver operator characteristic (ROC) curve analysis of VZ at 125 kHz as a predictor of PTD showed an area under the ROC curve of 1.00 and 0.77 and positive predictive values of 1.00 and 0.86, for the mifepristone and LPS models, respectively, suggesting that local VZ value can predict PTD. Histological examination of the LPS-treated model 6 h post-treatment revealed increased expression of sulfomucins and/or sulfated proteoglycans and sialomucins in the cervical epithelium, cervical stroma and vaginal stroma. In conclusion, local VZ values can determine sulfated and sialylated glycocalyx alterations within the uterus and vagina and might be a useful PTD prediction parameter.

Pravastatin is a promising medication to treat preeclampsia. However, the appropriate dose of pravastatin for managing preeclampsia has not been established. In this in vitro study, we examined the effects of low concentrations of pravastatin (0.01 to 10 µM) under hypoxic conditions on two types of placental cells and found that pravastatin decreased sFlt-1 levels up to 34% in cytotrophoblast cells isolated from human term placentas. Furthermore, we showed that sFlt-1 levels in HTR-8/SVneo cells, a cell line derived from first trimester trophoblast cells, decreased after exposure to very low concentrations of pravastatin (0.01, 0.1 µM). We also examined the effects of pravastatin on uterine spiral artery remodeling-related events and showed in wound healing and tube formation assays that low concentrations of pravastatin upregulated cell migration and invasion in HTR-8/SVneo cells. These results demonstrated that a low dose of pravastatin has in vitro effects that suggest a potential for anti-preeclamptic effects in vivo.
RESUMO
Japan has a particularly critical situation surrounding its collapsed HPV vaccination program for preventing HPV-caused cervical cancers, a problem exacerbated by the lack of a national immunization database. We have determined the year-to-year HPV vaccination uptake by Japanese females and analyzed by birth fiscal year (FY) the monthly number of people receiving initial HPV vaccination. Our analysis covers the period from the start of public subsidies in 2010 to September 2023, using data provided by local governments. We calculated the cumulative number of monthly immunizations for those unimmunized as of April (the beginning of each vaccination year). The monthly number of initial HPV vaccinations was highest in August for every FY from FY 2010 to FY 2023; a second vaccination peak tended to occur in March when the vaccination year ended. The highest number of August vaccinations occurred in FY 2011, followed (in order) by 2012, 2021, 2022, 2023, and 2013. In Japan's ongoing catch-up vaccination program for young women, the monthly number of vaccinations increased in August 2022 but then slowed the following year. After FY 2021, the cumulative vaccination coverage of subjects unvaccinated at the beginning of the vaccination year but subsequently covered by routine immunizations was slightly improved. FY 2021 was when the governmental recommendations for HPV vaccination were resumed. More recent vaccination rates are considerably lower than those in FY 2011-2012 when vaccinations were first fully endorsed. Paralyzing HPV vaccination hesitancy, which began in FY 2013, will linger in Japan in FY 2024.

In Japan, subsidies from local and national government programs for HPV vaccination of girls aged 13-16 began in 2010. By 2013, HPV vaccines were being used routinely for vaccinating girls aged 12-16 as part of its national immunization program. However, in June of 2013, in response to reports of possible adverse reactions to the vaccine, Japan's Ministry of Health, Labor, and Welfare (MHLW) announced a 'temporary suspension' of its governmental recommendation for HPV vaccination. The vaccination rate quickly dropped from 70 % of age-eligible girls to almost zero. It was not until 2021 that the government's recommendation suspension finally ended. The efficacy and safety of the HPV vaccine is now well documented, yet Japan has failed to reestablish any credible level of HPV vaccination. The World Health Organization (WHO) warned that Japan's HPV vaccination debacle was likely to result in real harm to the girls who lacked its protection; something we have already demonstrated with real-world data. To reinvigorate the HPV vaccination program in Japan to its prior levels, in the face of the current high level of HPV vaccine hesitancy, we will have to address the irrationality of human decision-making pointed out by behavioral economics. The Japanese government must act expeditiously to promote stronger cervical cancer control measures.
RESUMO
BACKGROUND: Hallux valgus and hallux rigidus are disorders affecting the first ray and are associated with hypermobility of this structure. This study aimed to investigate the three-dimensional mobility of each joint of the first ray between feet with hallux valgus or hallux rigidus and healthy feet using weightbearing and nonweightbearing computed tomography (CT). METHODS: This case-control study analyzed 17 feet of 11 healthy volunteers (control group), 16 feet of 16 patients with hallux valgus (HV group), and 16 feet of 11 patients with hallux rigidus (HR group). First, nonweightbearing foot CT imaging was performed in the supine position on a loading device with no load applied, with the legs extended and the ankle in the neutral position. Next, a load equivalent to body weight was applied for weightbearing CT imaging. Distal bone displacement relative to the proximal bone was quantified three-dimensionally under both conditions. RESULTS: In the HV group, the talonavicular joint showed significantly greater eversion (P = 00.011) compared with the control group and significantly greater dorsiflexion (P = 00.027) and eversion (P < 00.01) compared with the HR group. In the medial cuneiform joint, the HV group showed significantly greater eversion (P < 00.01) and abduction (P = 00.011) than the control group. For the first tarsometatarsal joint, the HV group showed significantly greater dorsiflexion (P = 00.014), inversion (P = 00.028), and adduction (P < 00.01) than the control group, and greater inversion (P < 00.01) and adduction (P < 00.01) than the HR group. Dorsiflexion of the first tarsometatarsal joint was significantly greater in the HR group compared with the control group (P = 00.026). CONCLUSION: Hypermobility of the first ray appears to be three-dimensional: in hallux valgus, it is centered at the first tarsometatarsal joint, while in hallux rigidus it is mainly in the sagittal plane at the first tarsometatarsal joint only. This difference may explain the different deformities ultimately observed in each condition.
RESUMO
RNA interference is a powerful gene-silencing tool with potential clinical applications. However, its therapeutic use is challenging because suitable carriers are unavailable. Exosomes are stable small endogenous vesicles that can transport functional molecules to target cells, making them ideal small interfering RNA (siRNA) carriers. Herein, we elucidated the therapeutic potential of patient-derived exosomes as an siRNA carrier for ovarian cancer (OC) treatment. The exosomes were extracted from the culture medium of primary fibroblasts collected from the omentum of patients with OC during surgery. MET proto-oncogene, receptor tyrosine kinase (MET) was selected for gene silencing, c-Met siRNAs were synthesized and loaded into the exosomes (Met-siExosomes) via electroporation, and the treatment effect of the Met-siExosomes was assessed in vitro and in vivo. The Met-siExosomes downregulated the c-Met protein levels and inhibited OC cell proliferation, migration, and invasion. In xenograft experiments using SKOV3-13 and ES-2 cells, Met-siExosomes were selectively extracted from peritoneally disseminated tumors. Intraperitoneal treatment suppressed the c-Met downstream targets in cancer cells and prolonged mouse survival. The synthesized siRNAs were successfully and selectively delivered via the exosomes to intraperitoneally disseminated tumors. As patients with OC routinely undergo omentectomy and abundant fibroblasts can be easily collected from the omentum, patient-derived exosomes may represent a promising therapeutic siRNA carrier to treat OC.
RESUMO
CASE: The patient was an 18-year-old man who had sustained diaphyseal fractures of the left femur and tibia in a traffic accident and underwent surgery at another hospital. A severe left foot equinovarus deformity developed in the early after surgery. The patient's left foot deformity was addressed using unconstrained gradual external fixator correction (the Matsushita method) in combination with soft-tissue contracture through Achilles tendon lengthening and was maintained after removing the external fixation. CONCLUSION: The Matsushita method can be effective in the correction of post-traumatic equinovarus foot deformities.

Severe cases of hemolysis, elevated liver enzymes, and low platelet (HELLP) syndrome requiring plasma exchange or dialysis should be differentiated from other thrombotic microangiopathy (TMA) and treated appropriately. To evaluate the prevalence and clinical characteristics of such cases in Japan, a questionnaire-based survey was conducted among obstetricians who are members of the Perinatal Research Network Group in Japan. There were a total of 335 cases of HELLP syndrome over a 3-year period in the 48 facilities that responded to the survey. Four patients required plasma exchange or dialysis, of which two were diagnosed with atypical hemolytic uremic syndrome and two with TMA secondary to systemic lupus erythematosus. Although such severe HELLP syndrome is rare, identifying the clinical features and making accurate differential diagnosis are critical for optimal clinical outcomes for mothers and neonates.

Pancreatic fistulas are rare after gynecologic surgeries but are sometimes difficult to manage. A 62-year-old woman was admitted to a local hospital with acute abdominal pain. Computed tomography (CT) images showed subileus and an obstruction site in the transverse/descending colon, with invasion of peritoneal metastasis. A metal stent was placed in the bowel through colonoscopy. Suspecting advanced-stage ovarian cancer, the patient was referred to a tertiary hospital. Diagnostic laparoscopy was performed prior to neoadjuvant chemotherapy. Due to concerns raised by gastrointestinal surgeons regarding the high risk of stent perforation during chemotherapy, an abdominal colectomy of the transverse/descending colon was performed along with the removal of the disseminated tumor and the stent. Post-surgery, the patient was histologically diagnosed with stage IVB left fallopian tube carcinosarcoma. On postoperative day 3, the patient developed a fever, and CT images showed an abscess around the pancreas/spleen, prompting the placement of a drainage tube. The amylase level in the drained fluid was 258,111 U/L, leading to a diagnosis of a pancreatic fistula. Conservative management was undertaken, with drainage, fasting, and octreotide administration. After two months, the drainage tube was removed as the volume of drained fluid had decreased. After four cycles of carboplatin/paclitaxel chemotherapy, CT images showed partial response to chemotherapy, and interval debulking surgery was performed. The necessity of metallic stent placement should be carefully considered as the subileus caused by peritoneal metastasis might be alleviated by the induction of chemotherapy for gynecologic cancer.
RESUMO
We experienced two cases of intractable hallux ganglion. Case 1 was a 70-year-old woman with a recurrent ganglion and severe pain on the plantar aspect of the hallux. The continuity between the mass and the distal flexor hallucis longus (FHL) tendon sheath was confirmed. The ganglion was resected along with part of the tendon sheath, and the tendon sheath was incised as proximally as possible. Case 2 was a 69-year-old woman with a ganglion on the dorsal aspect of the interphalangeal joint that repeatedly ruptured due to thinning of the skin. The ganglion was contiguous with the joint capsule but not with the FHL tendon sheath, and the entire capsule was resected. There was no recurrence one year after surgery in either case. The risk of recurrence of an intractable hallux ganglion can be reduced by blocking the synovial supply route and lowering the pressure inside the joint or tendon sheath.
RESUMO
Purpose: The coronavirus disease of 2019 (COVID-19) pandemic has increased public awareness of infectious diseases and interest in vaccines, including the human papilloma virus (HPV) vaccine. We investigated differences between parental gender and intentions to vaccinate their child for HPV and COVID-19. Methods: We analyzed data from Japan's COVID-19 and Society Internet Survey (JACSIS), a web-based cross-sectional survey of 2,444 respondents in 2021. Results: Females were more knowledgeable and more afraid of HPV and COVID-19 than males. The proportions of females in favor of, or against, HPV vaccination was higher than among males. The fathers' intention for HPV vaccination was significantly associated with the child's gender, knowledge regarding HPV, and intention to inoculate with the COVID-19 vaccine. The mothers' intention was also associated with her knowledge of HPV and her intention to seek the COVID-19 vaccine, but it included a greater fear of HPV infection. Both male and female parents favored the COVID-19 vaccine over the HPV vaccine. Parents approving of COVID-19 vaccination believed in the overall efficacy of vaccines and were more receptive to opinions from the administration and physicians, even if the parent was currently against HPV vaccination. Conclusions: Mothers were more knowledgeable about HPV and more favorable to vaccinate their child for HPV than fathers. The intention to have children COVID-19 vaccinated was also higher than for HPV vaccination. During this period of heightened public interest in vaccines due to the COVID-19 pandemic, this is a good time to educate and inform the public about HPV.
RESUMO
A 17-year-old girl sprained her left ankle and was diagnosed with a lateral malleolar fracture. She was treated conservatively for six months but had medial ankle pain with activity. Imaging revealed an oblique lateral malleolar fracture, with posterolateral displacement and partial fusion of the bone fragments, and bone marrow edema on the medial articular surface of the talus and medial malleolus. We diagnosed ankle instability due to delayed union with a displacement of the lateral malleolus, which caused an osteochondral lesion. We performed arthroscopic and open surgery eight months after the injury, reducted the lateral malleolus anatomically, and fixed it with a plate. Postoperatively, the pain improved rapidly, and the bone marrow edema had almost disappeared on an MRI. In this case, we think rotational instability of the ankle mortise caused abnormal pressure and continuous stress on the medial malleolus after injury, which may have contributed to persistent medial ankle pain.
RESUMO
BACKGROUND: One life event that requires extensive resilience and adaptation is parenting. However, resilience and perceived support in child-rearing vary, making the real-world situation unclear, even with postpartum checkups. OBJECTIVE: This study aimed to explore the psychosocial status of mothers during the child-rearing period from newborn to toddler, with a classifier based on data on the resilience and adaptation characteristics of mothers with newborns. METHODS: A web-based cross-sectional survey was conducted. Mothers with newborns aged approximately 1 month (newborn cohort) were analyzed to construct an explainable machine learning classifier to stratify parenting-related resilience and adaptation characteristics and identify vulnerable populations. Explainable k-means clustering was used because of its high explanatory power and applicability. The classifier was applied to mothers with infants aged 2 months to 1 year (infant cohort) and mothers with toddlers aged >1 year to 2 years (toddler cohort). Psychosocial status, including depressed mood assessed by the Edinburgh Postnatal Depression Scale (EPDS), bonding assessed by the Postpartum Bonding Questionnaire (PBQ), and sleep quality assessed by the Pittsburgh Sleep Quality Index (PSQI) between the classified groups, was compared. RESULTS: A total of 1559 participants completed the survey. They were split into 3 cohorts, comprising populations of various characteristics, including parenting difficulties and psychosocial measures. The classifier, which stratified participants into 5 groups, was generated from the self-reported scores of resilience and adaptation in the newborn cohort (n=310). The classifier identified that the group with the greatest difficulties in resilience and adaptation to a child's temperament and perceived support had higher incidences of problems with depressed mood (relative prevalence [RP] 5.87, 95% CI 2.77-12.45), bonding (RP 5.38, 95% CI 2.53-11.45), and sleep quality (RP 1.70, 95% CI 1.20-2.40) compared to the group with no difficulties in perceived support. In the infant cohort (n=619) and toddler cohort (n=461), the stratified group with the greatest difficulties had higher incidences of problems with depressed mood (RP 9.05, 95% CI 4.36-18.80 and RP 4.63, 95% CI 2.38-9.02, respectively), bonding (RP 1.63, 95% CI 1.29-2.06 and RP 3.19, 95% CI 2.03-5.01, respectively), and sleep quality (RP 8.09, 95% CI 4.62-16.37 and RP 1.72, 95% CI 1.23-2.42, respectively) compared to the group with no difficulties. CONCLUSIONS: The classifier, based on a combination of resilience and adaptation to the child's temperament and perceived support, was able identify psychosocial vulnerable groups in the newborn cohort, the start-up stage of childcare. Psychosocially vulnerable groups were also identified in qualitatively different infant and toddler cohorts, depending on their classifier. The vulnerable group identified in the infant cohort showed particularly high RP for depressed mood and poor sleep quality.
RESUMO
Importance: Women with a high level of autistic traits in the general population may experience larger health disparities during pregnancy, particularly women diagnosed with autism spectrum disorder (ASD), which in turn may be associated with increased risk of adverse birth outcomes. Objective: To investigate the association between maternal autistic traits and the risk of adverse birth outcomes in the general population. Design, Setting, and Participants: This cohort study included mothers of singletons from a nationwide, multicenter prospective birth cohort, the Japan Environmental Children's Study. Expecting mothers were recruited between January 2011 and March 2014. Data were analyzed between June 2021 and November 2023. Exposures: Autistic traits were self-reported during the second and third trimesters using the short form of the Autism-Spectrum Quotient Japanese version (AQ-J10) (score range, 0-10; clinical range, ≥7). Main Outcomes and Measures: Data on preterm birth (<37 weeks' gestation) and neonates born small for gestational age (SGA) were transcribed from medical records. Additional analysis of gestational age groups (very preterm birth, <32 weeks' gestation; moderate-to-late preterm birth, 32-36 weeks' gestation) was also performed. Results: Among 87â¯687 women (mean [SD] age, 31.2 [5.0] years) included in the study, 2350 (2.7%) had AQ-J10 scores within the clinical range yet only 18 (0.02%) were diagnosed with ASD. A higher AQ-J10 score was associated with an increased risk of all birth outcomes, including preterm births (relative risk [RR] per 1-SD increase, 1.06; 95% CI, 1.03-1.09), moderate-to-late preterm births (RR per 1-SD increase, 1.05; 95% CI, 1.01-1.08), very preterm births (RR per 1-SD increase, 1.16; 95% CI, 1.06-1.26), and child born SGA (RR per 1-SD increase, 1.04; 95% CI, 1.01-1.06) after adjusting for maternal and pregnancy-related factors. The risks of all outcomes increased with higher AQ-J10 scores; compared with women below the clinical range, women within the clinical range had greater risk of preterm births (RR, 1.16; 95% CI, 1.07-1.26), moderate-to-late preterm births (RR, 1.12; 95% CI, 1.03-1.22), very preterm births (RR, 1.49; 95% CI, 1.18-1.89), and a child born SGA (RR, 1.11; 95% CI, 1.04-1.19). Conclusions and Relevance: In this cohort study, higher level of maternal autistic traits was associated with increased risk of adverse birth outcomes, particularly very preterm birth. Acknowledging the risks and providing tailored and timely antenatal care support to women with a high level of autistic traits in the general population, particularly women with autistic traits within the clinical range, regardless of formal diagnosis, is warranted.
