Profiles of inflammatory cytokines following colorectal surgery: relationship with wound healing and outcome.

Inflammation is an essential component of normal wound healing. This study has correlated systemic (plasma) and local (wound fluid) concentrations of inflammatory cytokines (interleukin [IL]-6, tumor necrosis factor-alpha [TNF-alpha], and IL-1beta) with wound healing and surgical outcome following elective colorectal surgery. Paired plasma and wound fluid samples were collected (n = 44) postoperatively (days 1, 3, 5, 7) and analyzed by enzyme-linked immunosorbent assay (pg/mL).

Impaired expression of endometrial differentiation markers and complement regulatory proteins in patients with recurrent pregnancy loss associated with antiphospholipid syndrome.

Antiphospholipid syndrome (APS), characterized by circulating antiphospholipid (aPL) antibodies, is a major cause of early pregnancy failure and placental insufficiency. In this study, we examined whether impaired endometrial differentiation before conception contributes to the high incidence of pregnancy complications in APS. Timed secretory endometrial biopsies were obtained from a cohort of women with recurrent pregnancy loss (RPL).

Thromboelastography, whole-blood haemostasis and recurrent miscarriage.

Background: Some cases of recurrent miscarriage have a thrombotic basis. Thromboelastography is a rapid, reproducible test of whole-blood haemostasis.

Methods: Thromboelastography was performed in 494 consecutive, non-pregnant women (median age 35 years; range 21-48) with a history of miscarriages at <12 weeks gestation (median 4; range 3-12) and 55 parous women (median age 33 years; range 20-41) with no history of pregnancy loss.

Growth factor profiles in intraperitoneal drainage fluid following colorectal surgery: relationship to wound healing and surgery.

Cytokines and growth factors are important at each stage of wound healing. This study aims to determine the changing profiles of these factors in intraperitoneal drainage, acute wound fluid, following colorectal surgery, and to correlate levels to wound healing and surgical outcomes. Acute wound fluid samples (n = 52 patients) were collected daily from postoperative day 1 until drain removal.

Placental pathology, antiphospholipid antibodies, and pregnancy outcome in recurrent miscarriage patients.

Objective: To examine whether there are characteristic histological features in placentas from ongoing pregnancies of patients with a history of recurrent miscarriage, with and without primary antiphospholipid antibody syndrome, in relation to clinical pregnancy outcome.

Methods: Patients attending a recurrent miscarriage clinic were investigated and treated according to an established protocol. One hundred twenty-one consecutive patients achieving a potentially viable pregnancy (at least 24 completed weeks' gestation), including 60 primary antiphospholipid antibody syndrome-positive cases and 61 primary antiphospholipid antibody syndrome-negative cases were included.
