Teng T, Yang Y, Li H, Song J, Ren J, Liu F. Mechanisms of intestinal injury in polychaete Perinereis aibuhitensis caused by low-concentration fluorene pollution: Microbiome and metabonomic analyses. JOURNAL OF HAZARDOUS MATERIALS 2024; 475:134925. [PMID: 38889458 DOI: 10.1016/j.jhazmat.2024.134925] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/19/2024] [Revised: 05/31/2024] [Accepted: 06/13/2024] [Indexed: 06/20/2024]
Abstract
The polychaete Perinereis aibuhitensis is used for bioremediation; however, its ability to remove fluorene, a common environmental pollutant, from sediments remains unclear, especially at low concentrations of fluorene (10 mg/kg). In this study, we explored the mechanism of intestinal injury induced by low concentrations of fluorene and the reason intestinal injury is alleviated in high fluorene concentration groups (100 and 1000 mg/kg) using histology, ecological biomarkers, gut microbiome, and metabolic response analyses. The results show that P. aibuhitensis showed high tolerance to fluorene in sediments, with clearance rates ranging 25-50 %. However, the remediation effect at low fluorene concentrations (10 mg/kg) was poor. This is attributed to promoting the growth of harmful microorganisms such as Microvirga, which can cause metabolic disorders, intestinal flora imbalances, and the generation of harmful substances such as 2-hydroxyfluorene. These can result in severe intestinal injury in P. aibuhitensis, reducing its fluorene clearance rate. However, high fluorene concentrations (100 and 1000 mg/kg) may promote the growth of beneficial microorganisms such as Faecalibacterium, which can replace the dominant harmful microorganisms and improve metabolism to reverse the intestinal injury caused by low fluorene concentrations, ultimately restoring the fluorene-removal ability of P. aibuhitensis. This study demonstrates an effective method for evaluating the potential ecological risks of fluorene pollution in marine sediments and provides guidance for using P. aibuhitensis for remediation.

The association between blood pressure control in women during pregnancy and adverse perinatal outcomes: the TMM BirThree Cohort Study. Hypertens Res 2024; 47:1216-1222. [PMID: 38238512 PMCID: PMC11073994 DOI: 10.1038/s41440-023-01570-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2023] [Revised: 12/07/2023] [Accepted: 12/16/2023] [Indexed: 05/08/2024]
Abstract
Blood pressure (BP) control in pregnancy is essential to prevent adverse outcomes. However, BP levels for hypertension treatment are inconsistent among various guidelines. This study investigated the association between BP control and adverse perinatal outcomes. A total of 18,155 mother-offspring pairs were classified into four groups according to BP after 20 gestational weeks: normal BP (<140/90 mmHg without antihypertensive drugs), high BP (≥140/90 mmHg without antihypertensive drugs), controlled BP (<140/90 mmHg with antihypertensive drugs), and uncontrolled BP (≥140/90 mmHg with antihypertensive drugs). The prevalence of small for gestational age was 1,087/17,476 offspring in normal BP, 78/604 in high BP, 5/42 in controlled BP, and 7/33 in uncontrolled BP. Compared to normal BP, adjusted odds ratios (ORs) (95% confidence intervals (CIs)) were 1.76 (1.32-2.35) for high BP, 2.08 (0.79-5.50) for controlled BP, and 2.34 (0.94-5.85) for uncontrolled BP (multiple logistic regression analysis). Similarly, the adjusted ORs (95% CIs) were 1.80 (1.35-2.41), 3.42 (1.35-8.63), and 5.10 (1.93-13.45) for high, controlled, and uncontrolled BPs for low birth weight, respectively; 1.99 (1.48-2.68), 2.70 (1.12-6.50), and 6.53 (3.09-13.82) for high, controlled, and uncontrolled BPs for preterm birth, respectively; 1.64 (1.19-2.24), 2.17 (0.88-5.38), and 2.12 (0.80-5.65) for high, controlled, and uncontrolled BPs for admission to the Neonatal Intensive Care Unit or Growing Care Unit, respectively; and 1.17 (0.70-1.95), 2.23 (0.65-7.68), and 0.91 (0.20-4.16) for high, controlled, and uncontrolled BPs for 1-min Apgar score < 7, respectively. BP ≥ 140/90 mmHg might be taken care for preventing various adverse perinatal outcomes.

Ishikawa T, Kawame H, Mano N, Obara T. Real-world prevalence, time of diagnosis, and co-occurrence patterns of birth defects in live-born infants, 2014-2020: A health administrative database study in Japan. Birth Defects Res 2023; 115:1723-1736. [PMID: 37688289 DOI: 10.1002/bdr2.2247] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Revised: 08/07/2023] [Accepted: 08/23/2023] [Indexed: 09/10/2023]
Abstract
BACKGROUND A study evaluating the real-world prevalence of birth defects (BDs), including co-occurrence patterns, will provide the information required to estimate Japan's true BD prevalence and monitor it. Information such as when infants are diagnosed with BDs is crucial for defining the study population and data collection period in future administrative database studies. METHODS This study utilized the DeSC database, a large claims database comprising multiple health insurance schemes. The prevalence of major BDs, including structural congenital malformations (CMs) and chromosomal abnormalities, was determined in infants born between 2014 and 2020 and continuously insured for ≥1 year. The time of the first BD diagnosis and multiple BD patterns were also evaluated. RESULTS Among 43,147 infants, 3050 (7.07%) were diagnosed with major BDs, and 3002 (6.96%) with major CMs. The circulatory system (2.95%) was the most frequent organ system affected by CMs, followed by CMs and deformations of the musculoskeletal system (1.94%). The cumulative diagnostic rates of BDs and CMs at month 6 were 85.9% and 85.6%, respectively. The EUROCAT BD subgroups diagnosed in more than 1.0% of the infants were atrial septal defects (1.47%) and patent ductus arteriosus (1.07%). Among the 2997 infants with EUROCAT BDs, 241 (8.04%) were classified as having multiple BDs. CONCLUSIONS A large claims database is a valuable resource for evaluating and monitoring the prevalence of BDs, including multiple patterns. At least 1 year since birth should be considered in future administrative database studies evaluating BDs as outcomes.

Segovia Chacón S, Karlsson P, Cesta CE. Detection of major congenital malformations depends on length of follow-up in Swedish National Health Register Data: Implications for pharmacoepidemiological research on medication safety in pregnancy. Paediatr Perinat Epidemiol 2023. [PMID: 37818747 DOI: 10.1111/ppe.13011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/13/2023] [Revised: 09/15/2023] [Accepted: 09/20/2023] [Indexed: 10/13/2023]
Abstract
BACKGROUND In observational medication pregnancy safety studies, children are often followed from birth to 1 year of age. However, some major congenital malformations (MCM) may take longer to diagnose. OBJECTIVES We aimed to investigate the proportion of children with detected MCMs at different lengths of follow-up and compare them to the proportion detected at 1 year after birth. METHODS This population-based register study included all singleton children liveborn in Sweden from 2006 to 2016. MCM were identified by ICD-10 codes in the Medical Birth Register and National Patient Register, aligned to the EUROCAT classification system. Cumulative proportion of children with detected MCM at birth, 90 days, 1, 2, and 3 years was calculated and compared between children born preterm and at term. RESULTS In 1,138,113 liveborn children, the cumulative proportion of children with a detected MCM increased from 1.9% at birth to 3.1%, 3.9%, 4.4% and 4.7% at 90 days, 1, 2, and 3 years after birth, respectively, and varied by MCM subgroup. MCMs of the eye, ear-face-neck, nervous system and genitals were detected with the longest delay, with 31%-59% more detected at 3- versus 1-year follow-up. Compared to children born at term, the proportion of children with any MCM was 2.5 times higher amongst preterm children, with a higher proportion detected over the first 90 days for most MCM subgroups. CONCLUSIONS The proportion of children with a detected MCM varied by MCM subgroup and follow-up time. In pharmacoepidemiology studies of medication safety in pregnancy using Swedish national data, the length of child follow-up should be chosen in accordance with the expected age at detection if a specific subgroup of MCM is under investigation, for example, eye and genital MCM require longer follow-up for detection than abdominal wall and digestive system MCM. However, in most circumstances, 1 year of follow-up is sufficient.
