Invasive species control is important for ecological and agricultural management. Genetic methods can provide species specificity for population control. We developed heritable maternal effect embryo lethality (HMEL), a novel strategy allowing negative population pressure from HMEL individuals to be transmitted within a population across generations. We demonstrate the HMEL technique in zebrafish through genome-integrated CRISPR/Cas targeted mutagenic disruption of , a female-specific essential maternal effect gene, causing heritable sex-limited disruption of reproduction. -induced high-efficiency mutation of in females suppresses population, while males transmit the allele across generations. HMEL could be easily modified to target other genes causing sex-specific sterility, or generalized to control invasive fish or other vertebrate species for environmental conservation or agricultural protection.

An Atypical Case of Neonatal Alloimmune Thrombocytopenia.

Fetal and neonatal alloimmune thrombocytopenia (FNAIT) results from maternal antibodies targeting fetal platelets during pregnancy, often causing hemorrhagic manifestations detectable antenatally or shortly after birth. We report an atypical form of FNAIT with delayed onset in a healthy, breastfed male infant who developed diffuse petechiae 2 weeks after birth due to severe thrombocytopenia. The mother was shown to be negative for the human platelet antigen-1a (HPA-1a) allele but had anti-HPA-1a IgG antibodies, while the father and newborn were HPA-1a positive, confirming the diagnosis.

Cesarean sections (c-sections) are the most commonly performed surgery in the United States, and the country is currently facing a maternal health crisis. Surprisingly, women do not receive rehabilitation services to support the acute stages of c-section recovery. When someone undergoes a knee or hip replacement, it is standard practice for the physician to order home health services, including occupational therapy, for a client before they are discharged from the hospital.

Importance: Preventive efforts in pregnancy-related alloimmunization have considerably decreased the prevalence of hemolytic disease of the fetus and newborn (HDFN). International studies are therefore essential to obtain a deeper understanding of the postnatal management and outcomes of HDFN. Taken together with numerous treatment options, large practice variations among centers may exist.

: The utilization of maternal health services at the primary healthcare level is still considered an effective approach despite the critical role in improving maternal health outcomes. The study aimed to assess the influence of sociodemographic characteristics and interpersonal support on the use of maternal health services in three regions of the Province of Jambi, Indonesia. : Using a mixed-methods sequential explanatory design, a quantitative survey of 432 women and qualitative focus group discussions with nine families were conducted.

Background: Abortion-related complications significantly contribute to maternal morbidity and mortality globally. Post-abortion care (PAC) services are essential to safeguarding women's rights by substantially mitigating the health risks associated with abortions - a step which is fundamental to achieving reproductive and maternal health-related Sustainable Development Goals.
Methods: We conducted a secondary analysis of data from the nationally representative Service Provision Assessment (SPA) surveys conducted between 2015 and 2024 across three regions in seven low- and middle-income countries: Afghanistan, Bangladesh, Nepal, the Democratic Republic of Congo (DRC), Ethiopia, Senegal, and Haiti.
