Complications throughout the peripartum period may be caused by preexisting conditions or pregnancy-induced conditions and may alter pharmacotherapy management. Pharmacotherapy management during late pregnancy and delivery requires careful consideration due to changing hormones, hemodynamic status, and pharmacokinetics, and concerns for potential maternal and/or fetal morbidity. Increased maternal and fetal monitoring are often required and may lead to therapy changes.

Our aim was to review the efficacy, safety, and pharmacology of brexanolone (Zulresso), a new antidepressant with a novel mechanism of action, in the treatment of postpartum depression (PPD). Pertinent data and information were obtained via PubMed (1993 to August 2018). Articles published in English that evaluated the safety and efficacy of brexanolone and other off-label PPD treatments were included.

We aimed to investigate why general practitioners (GPs) continue to prescribe antibiotics for ARTIs despite increasing knowledge of their poor efficacy and worsening antimicrobial resistance.
Methods: We used an explorative qualitative study design.
This study investigated the expression and function of transient receptor potential vanilloid type-3 ion channels (TRPV3) in uterine radial arteries isolated from non-pregnant and twenty-day pregnant rats. Immunohistochemistry (IHC) suggested TRPV3 is primarily localized to the smooth muscle in arteries from both non-pregnant and pregnant rats. IHC using C' targeted antibody, and qPCR of TRPV3 mRNA, suggested pregnancy increased arterial TRPV3 expression.

Summary Answer: Estimated losses of 29.5% of first trimester pregnancies in the affected region could be associated with an acute calamity, with no statistically significant difference in estimated losses by fetal sex.
What Is Known Already: There are very few studies on the impact of a calamity on early pregnancy loss and its differential effects on male and female fetuses.
Preeclampsia is a systemic vascular disorder of pregnancy and is associated with increased sensitivity to angiotensin II (AngII) and hypertension. The cause of preeclampsia remains unknown. We identified the role of regulator of G protein (heterotrimeric guanine nucleotide-binding protein) signaling 5 (RGS5) in blood pressure regulation during pregnancy and preeclampsia.

The smaller volume of blood required for this test, compared with the more traditional pH estimation, may improve sampling rates. The appropriate use of this practice mandates systematic review of its safety and clinical effectiveness prior to widespread introduction.

The present study determines the distribution and density of caveolae, transient receptor potential vanilloid type 4 channels (TRPV4) and myoendothelial gap junctions, and the relative contribution of related endothelium-dependent vasodilator components in uterine radial arteries of control virgin non-pregnant and 20-day late-pregnant rats. The hypothesis examined is that specific components of endothelium-dependent vasodilator mechanisms are altered in pregnancy-related uterine radial artery remodelling.

This study assessed the accuracy of the Hadlock IV equation, the equation used at the Royal Hospital for Women, Randwick, NSW, in estimating birth weight. The accuracy of the Hadlock IV equation was assessed based on systematic and random error as well as absolute error.

This study aims to determine the Ca(2+) entry channels associated with altered vasoconstriction in pregnancy, with the hypothesis that augmented vasoconstriction involves transient receptor potential canonical type-3 (TRPC3) and L- and T-type voltage-dependent Ca(2+) channels. Immunohistochemistry showed TRPC3, L-type Cav1.

It is hypothesised that the resultant startle reflex in the fetus and subsequent fetal heart rate (FHR) acceleration or transient tachycardia following VAS provide reassurance of fetal well-being. This technique has been proposed as a tool to assess fetal well-being in the presence of a nonreassuring cardiotocographic (CTG) trace during the first and second stages of labour.

Eighty-eight women completed the Parental Bonding Instrument, self-report measures of anxiety and depression and a structured diagnostic interview (Mini-plus International Neuropsychiatric Interview) during the third trimester of pregnancy. The MINI-Plus and anxiety and depression measures were re-administered at 7 months postpartum.

Methods: An Internet-based survey was conducted of women after unexplained stillbirth, seeking information about their perceptions of management, and their wishes for care in a subsequent pregnancy.
Results: One hundred and five completed surveys were included in the study group.
Background: Unexplained stillbirth is the largest contributor to perinatal death, accounting for one-third of stillbirths. There appears to be no increase in perinatal death rates in the pregnancies that follow an unexplained stillbirth. However, these pregnancies have increased rates of induced labour and elective caesarean section, as well as preterm birth, low birthweight, instrumental delivery, 'fetal distress' and postpartum haemorrhage.

Epidemiology: Approximately 1 in 200 pregnancies will end in stillbirth, of which about one-third will remain unexplained. Unexplained stillbirth is the largest single contributor to perinatal mortality.
This study prospectively examined the separate and combined influences of maternal prenatal anxiety disorder and postnatal caregiving sensitivity on infants' salivary cortisol responses to the still-face procedure. Effects were assessed by measuring infant salivary cortisol upon arrival at the laboratory, and at 15-, 25-, and 40-min following the still-face procedure. Maternal symptoms of anxiety during the last 6 months of pregnancy were assessed using clinical diagnostic interview.

However, availability of these compounds may be decreased in patients with short bowel syndrome (SBS) due to decreased oral intake of fruits and vegetables and/or decreased intestinal absorption. Little information is available on serum concentrations of carotenoids, vitamin A, and tocopherols during chronic parenteral nutrition (PN) or during PN weaning.
View Article and Find Full Text PDFObjectives: Little data are published on the habitual home oral diet of patients with short bowel syndrome (SBS).
Methods: We assessed nutrient intake from oral food and beverages in 19 stable patients with severe SBS who live in the southeastern United States. Intestinal absorption of energy, fat, nitrogen (N), and carbohydrate (CHO) was determined in a metabolic ward.
Background: Glutamine (Gln) may become conditionally indispensable during critical illness. The short-term metabolic effects of enteral versus parenteral Gln supplementation are unknown in this clinical setting.
Objectives: We studied metabolic effects of intravenous (i.
Gut barrier dysfunction may occur in short bowel syndrome (SBS). We hypothesized that systemic exposure to flagellin and lipopolysaccharide (LPS) in SBS might regulate specific immune responses. We analyzed serial serum samples obtained from parenteral nutrition (PN)-dependent patients with SBS versus non-SBS control serum.

Citrulline (Cit) is a product of the metabolism of glutamine (Gln) and derived amino acids by enterocytes. Cit is produced almost exclusively by the gut, which is also a major site of Gln metabolism.

Human growth hormone (hGH) has been shown in some studies to have anabolic effects on bone, but hGH effects on bone in patients with SBS are unknown.
Methods: Adults with PN-dependent SBS underwent a 7-day period of baseline studies while receiving usual oral diet and PN and then began receiving modified diets designed to improve nutrient absorption and daily oral calcium/vitamin D supplements (1500 mg elemental calcium and 600 IU vitamin D, respectively).
