Availability of reimbursement for CoCM Medicaid billing codes in North Carolina did not immediately result in robust utilization of CoCM.

Substance use is prevalent among youth in postconflict African countries and is associated with a number of public health problems such as poverty, child homelessness, and school truancy. This qualitative study explores the risk factors associated with substance use among Liberian youth from the perspective of public-school students. Nine focus groups were conducted with 72 Liberian public-school students (35 female, 37 male).

Access to education has been shown to strongly influence adolescent health across the world, and strong relationships with teachers has been found to lead to better academic and psychosocial outcomes for students. In many low-income countries where adolescents have less access to education and are more likely to experience poor health outcomes, risky sexual behaviors can exacerbate these challenges by increasing the risk of unintended pregnancy and sexually transmitted infections. This study sought to examine risky behaviors, such as substance use and risky sexual practices, of in-school youth in Liberia, a country in West Africa.

Liberians have experienced significant psychological trauma following fourteen years of violent civil war and the 2014-2015 Ebola epidemic, but there are only two psychiatrists for the entire population. However, many traditional healers commonly treat mental health-related illnesses throughout the country. This paper examines the potential for collaboration between traditional and Western medicine to close the mental health treatment gap in Liberia.

Repair of DNA damage is vital to the health and survival of all organisms. In Escherichia coli, a protein known as RadA (or Sms) participates in recombinational repair, a process that uses an undamaged DNA strand in one DNA duplex to fill a gap in a homologous DNA strand in a sister DNA duplex. In a prior report, we described the production of monoclonal antibodies (MAbs) specific for RadA.

Background: Prolonged QTc intervals have been associated with increased cardiac morbidity and mortality. We investigated whether pretreatment prolongation of the QTc interval was associated with increased cardiac-related events (CREs) in electroconvulsive therapy (ECT) treatment of psychiatric disorders.

Methods: The charts of 1437 ECT patients were reviewed for the presence of baseline QTc prolongation.

Oocyte maturation is dependent on a complex program of morphological, ultrastructural, and biochemical signaling events, and if disrupted could lead to decreased fertility and population decline. The in vitro sensitivity of amphibian oocytes and oocyte maturation to plant growth factor and widely used hormonal herbicide, 2,4-dichlorophenoxyacetic acid (2,4-D), was examined in this study to determine its potential impact on early development and possible contribution to the global amphibian decline. Progesterone, which acts through a membrane receptor, triggers meiotic maturation in full grown (stage VI) Xenopus oocytes, characterized by cytoskeletal reorganization, nuclear dissolution, chromosome condensation, and spindle formation.
