The dorsomedial cutaneous nerve to hallux provides sensation to the dorsomedial aspect of the first metatarsophalangeal joint and hallux. Postoperative damage to the dorsomedial cutaneous nerve to hallux have been reported with the dorsomedial approach and symptoms can be very debilitating. The present study aims to understand how the distance between this nerve and the extensor hallucis longus tendon are affected by the severity of the hallux valgus deformity, at the level of the first metatarsophalangeal joint. We performed a cadaveric study using 35 cadaveric lower extremities (N = 35). Each specimen was classified according to the hallux valgus severity through a 30 kg partial weight-bearing antero-posterior radiograph. Before dissection, the lower extremities' greater saphenous vein was injected with black latex to simplify the distinction between anatomical structures. We concluded that as the hallux valgus angle and the first intermetatarsal angle increase, the distance between the dorsomedial cutaneous nerve to hallux and the extensor hallucis longus tendon also increases, ranging from 12 mm in normal feet to 19 mm in severely deformed feet. Hallux valgus is a three-dimensional deformity that changes traditional surgical landmarks. To avoid harming this nerve, we established a danger zone ranging from 12 mm to 19 mm medial from the extensor hallucis longus tendon, at the level of the first metatarsophalangeal joint. The mid-medial approach to MTP should be preferred as it is out of the danger zone.

Is there a difference in fibrin clot phenotype in women with endometriosis before and after ovarian stimulation?

Prospective study including 73 infertile women in two age-matched groups (i) with confirmed endometriosis (n = 29); (ii) without endometriosis (n = 44). Assessments of plasma fibrin clot permeability (K

), efficiency of fibrinolysis using clot lysis time (CLT), along with thrombin generation (prothrombin fragments 1+2 [F1+2] and endogenous thrombin potential [ETP]) and fibrinolysis inhibitors were performed together with clinical pregnancy rate.

Endometriosis was associated with increased thrombin generation, reflected by both higher F1+2 (+96.1%, P = 0.005) and ETP (+14.2%, P = 0.014) along with unfavourably altered fibrin clot properties represented by lower K

(-31%, P< 0.001) and prolonged CLT (+13.5%, P = 0.02), compared with the non-endometriosis group. Moreover, women with endometriosis had higher plasminogen activator inhibitor-1 (PAI-1; +272%, P = 0.004) concentrations and alpha-2-antiplasmin activity (+39.9%, P< 0.001) in contrast to the other group. Ovarian stimulation led to reduction in F1+2 (-48.1%, P< 0.001), improvement of fibrin clot phenotype reflected by higher K

(+25.9%, P< 0.001) and shortened CLT (-11.9%, P< 0.001), along with lower PAI-1 (-54%, P = 0.016) compared with the baseline in women with endometriosis.

Endometriosis is associated with the prothrombotic fibrin clot phenotype and increased thrombin generation. Ovarian stimulation favourably alters fibrin clot properties and leads to comparable pregnancy outcomes to those in women without endometriosis.

Do bisphenol A (BPA) levels in maternal urine, serum and follicular fluid affect embryo quality and intracytoplasmic sperm hinjection (ICSI) cycle outcomes in women with unexplained infertility?

Prospective study conducted between 1 April 2019 and 30 September 2019. The study cohort consisted of 82 women aged between 23 and 33 years who underwent intracytoplasmic sperm injection owing to unexplained infertility and provided urine, blood and follicular fluid samples on the day of oocyte retrieval. Consumption of drinking water from plastic carboys or bottles at home were considered as chronic BPA exposure. Demographic features and IVF outcomes of the patients were collected.

Among the 82 women with unexplained infertility, clinical pregnancy was achieved in 22 (26.8%) patients after the IVF and embryo transfer cycle. The patients who consumed tap water had statistically significantly lower BPA values in three body fluids compared with patients who consumed plastic bottled water (all P < 0.001). Women who had grade 1 embryos transferred had lower serum BPA values than women who had grade 2 embryos transferred (10.8 ± 5.2 versus 26.9 ± 22 ng/ml, P = 0.003). Serum and follicular fluid BPA levels were statistically significantly higher in women who failed to achieve clinical pregnancy (P < 0.001, P = 0.006, respectively) and obtain a live birth (both P = 0.007).

A negative relationship was found between serum and follicular fluid BPA levels and embryo quality, clinical pregnancy and live birth in these women. Selleckchem Cyclopamine In addition, the BPA levels of women who consume tap water at home were lower than those who use plastic bottled water.

In the past, resistant parasites were generally identified following treatment failures in patients, and compounds would have to be abandoned late in development. An early understanding of how candidate therapeutics lose efficacy as parasites evolve resistance is important to facilitate drug design and improve resistance detection and monitoring up to the postregistration phase. We describe a new strategy to assess resistance to antimalarial compounds as early as possible in preclinical development by leveraging tools to define the Plasmodium falciparum resistome, predict potential resistance risks of clinical failure for candidate therapeutics, and inform decisions to guide antimalarial drug development.
