Spontaneous Heterotopic Pregnancy: A Case Report of a Potentially Life-Threatening Condition.

Heterotopic pregnancy involves the coexistence of both an intrauterine and an extrauterine pregnancy occurring simultaneously. The spontaneous incidence of heterotopic pregnancy in the general population has been estimated to be 1/30,000. This report discusses the case of a 37-year-old female who presented to the emergency department with vaginal bleeding and lower abdominal pain.

Changes in food behavior during the first lockdown of COVID-19 pandemic: A multi-country study about changes in eating habits, motivations, and food-related behaviors.

The COVID-19 pandemic resulted in severe, unprecedented changes affecting the world population. Restrictions in mobility, social distancing measures, and the persistent social alarm, during the first period of pandemic, resulted in dramatic lifestyle changes and affected physical and psychological wellbeing on a global scale. An international research team was constituted to develop a study involving different countries about eating motivations, dietary habits and behaviors related with food intake, acquisition, and preparation.

Ephrin-A3 is required for tonotopic map precision and auditory functions in the mouse auditory brainstem.

Tonotopy is a prominent feature of the vertebrate auditory system and forms the basis for sound discrimination, but the molecular mechanism that underlies its formation remains largely elusive. Ephrin/Eph signaling is known to play important roles in axon guidance during topographic mapping in other sensory systems, so we investigated its possible role in the establishment of tonotopy in the mouse cochlear nucleus. We found that ephrin-A3 molecules are differentially expressed along the tonotopic axis in the cochlear nucleus during innervation.

Associations between inpatient psychiatric admissions during pregnancy and adverse obstetrical and birth outcomes.

Background: Previous research supports an association between psychiatric diagnoses and adverse obstetrical and neonatal outcomes including low birthweight, preterm birth, and preeclampsia. Women who are admitted for inpatient psychiatric care are regarded as having more acute illnesses than those who are able to be managed as outpatients. Previous research has not yet investigated how the severity of psychiatric illness, as indicated by type of antenatal psychiatric care received, is associated with adverse obstetrical outcomes.

Chronic cerebrospinal venous insufficiency is unlikely to be a direct trigger of multiple sclerosis.

Background: Chronic cerebrospinal venous insufficiency, a vascular pathology affecting the veins draining the central nervous system can accompany multiple sclerosis and is suspected to be involved in its pathogenesis.

Objective: This study was aimed at exploring a potential role for chronic cerebrospinal venous insufficiency in triggering multiple sclerosis. If it were venous abnormalities responsible for neurological pathology, one should expect negative correlation, i.
