Placental deficiency during maternal SARS-CoV-2 infection.

Introduction: Maternal anti-SARS-CoV-2 Spike antibodies can cross the placenta during pregnancy, and neonates born to infected mothers have acquired antibodies at birth. Few studies reported data on the histopathological changes of the placenta during infection and placental infection. SARS-CoV-2 infection may cause impaired development of the placenta, thus predisposing maternal and fetal unfavorable outcomes.

L-arginine supplementation lowers blood pressure, protein excretion and plasma lipid profile in experimental salt-induced hypertension in pregnancy: Relevance to preeclampsia.

This study aimed to investigate the effects of L-arginine supplementation on blood pressure, protein excretion, lipid profile in salt-induced hypertensive pregnant rats. Female Sprague-Dawley rats were divided into 4 groups. Control Preg (normal rat chow).

The relationship between malaria parasitemia, malaria preventive measures and average birth weight of babies in a tertiary facility in Owerri, Nigeria.

Background: Despite the global efforts made to eradicate malaria, it continues to be a significant cause of morbidity and mortality in both neonates and the parturients. This study was done to determine the relationship between placental parasitemia, average neonatal birth weight and the relationship between the use of malaria preventive measures and the occurrence of placental parasitemia with the aim to improving maternal and neonatal outcome.

Patients And Methods: This cross-sectional study was done at the labor ward unit of the Federal Medical Center, Owerri, from December 2013 to May 2014.

Preoperative comorbidity and modes of failure in revision hip arthroplasty: a single-surgeon series in a tertiary referral centre.

Revision hip arthroplasty is associated with higher morbidity post-operatively than primary surgery. We reviewed data on 102 consecutive patients (124 procedures) undergoing revision hip arthroplasty by a single surgeon from January 2005 to June 2009 in 2 institutions. Indications of failure: 62% aseptic loosening, 15% infection, 11.

Closure vs non-closure of peritoneum at caesarean section: evaluation of pain.

We evaluated the effect of closure or non-closure of parietal and visceral peritoneum during caesarean section (CS) on post-caesarean pain and analgesic requirement. A total of 94 primigravidas planned for elective CS were prospectively enrolled into closure (n = 46) and non-closure (n = 48) groups. Analgesia was provided by a patient-controlled analgesia pump (PCA) postoperatively.
