Recent attention has focused on the length of the post partum period of infecundity in those societies where child-spacing has traditionally been achieved through post partum sexual abstinence or prolonged breast-feeding. The tabulation of proportions of women abstaining at interview by the age of the youngest child has been suggested as a technique free of problems of digital preference and memory lapse, while being otherwise equivalent to the distribution of the proportion of women abstaining by completed months since their last confinement, calculated from retrospectively-collected durations of abstinence. Both stochastic and deterministic models demonstrate that the techniques are comparable only when they are applied to non-recurrent events such as first marriage. Childbearing, and the relaxation of the proscription on post partum sexual intercourse, is a recurrent event, and the distribution of proportions of currently abstaining women according to the age of their youngest child is heavily biased. This finding invalidates the use of the post partum current status distribution.

Purpose: Pregnant and postpartum mothers with physical disabilities face discrimination in healthcare settings and high rates of maternal and obstetric complications, as well as having higher rates of lifetime depression prior to pregnancy, potentially increasing their likelihood of experiencing postpartum depression (PPD). Some studies have found higher rates of PPD in mothers with physical disabilities than in mothers without physical disabilities, with more disabling symptoms associated with worse PPD systems; however, the literature is sparse and heterogenous. This systematic review and meta-analysis advanced this area of study by evaluating the strength of the association between PPD and physical disability.

AbstractMorning Report is a time-honored tradition where physicians-in-training present cases to their colleagues and clinical experts to collaboratively examine an interesting patient presentation. The Morning Report section seeks to carry on this tradition by presenting a patient's chief concern and story, inviting the reader to develop a differential diagnosis and discover the diagnosis alongside the authors of the case. This report examines the story of a 26-year-old woman who developed acute hepatocellular liver injury following a cesarean delivery for fetal distress.

Background: Cerebral venous thrombosis (CVT) is a rare but potentially life-threatening condition characterized by the formation of a blood clot in the dural venous sinuses or cerebral veins. CVT presents a diverse array of clinical symptoms, making its diagnosis challenging. Understanding regional variations and specific risk factors associated with CVT is crucial, especially in low-resource settings like Somalia, where epidemiological data is limited and healthcare resources are scarce.

Report of a Rare Case of Acute Abdominal Pain Post-partum: Spontaneous Ureteral Rupture.

Cureus

December 2024

Radiology, West Suffolk NHS Foundation Trust, Bury St Edmunds, GBR.

Spontaneous ureteral rupture is a rare cause of acute abdominal pain, particularly unusual during pregnancy or the post-partum period. While pregnancy-related changes like ureteral compression and dilation may play a role, no definitive mechanisms have been established. Clinicians should suspect ureteric injury in post-partum patients with free pelvic fluid.
