Research question What is the performance of anti-Müllerian hormone (AMH) as measured by the Elecsys® AMH assay in predicting ovarian response in women treated with 150 µg corifollitropin alfa (CFA)? Design Multicentre, prospective study conducted between December 2015 and April 2018. Women were aged 18-43 years, had regular menstrual bleeding, a body mass index of 17-35 kg/m2 and weighed 60 kg or over. Exclusion criteria previous oophorectomy, history of ovarian hyperstimulation syndrome, a previous IVF and intracytoplasmic sperm injection cycle producing over 30 follicles measuring 11 mm or wider, basal antral follicle count (AFC) over 20 or polycystic ovarian syndrome. All women were treated with 150 μg CFA followed by recombinant FSH (150-300 IU/day) in a fixed gonadotrophin releasing hormone antagonist protocol. Results Of the 219 patients enrolled, 22.8% had low ovarian response (three or fewer oocytes), 66.2% had normal response and 11% had high ovarian response (15 or more oocytes). The AMH and AFC presented an area under the curve of 0.883 (95% CI 0.830 to 0.936) and 0.879 (95% CI 0.826 to 0.930), respectively, for low ovarian response; and an AUC of 0.865 (95% CI 0.793 to 0.935) and 0.822 (95% CI 0.734 to 0.909) for high ovarian response. An AMH cut-off of 1.0 ng/ml provided a sensitivity of 92.0% and a specificity of 66.9% in the prediction of low ovarian response; a cut-off of 2.25 ng/ml predicted high ovarian response with a sensitivity of 54.2% and a specificity of 91.8%. Conclusions The automated Elecsys® AMH assay predicts ovarian response in a CFA antagonist protocol. The best predictors of ovarian response in CFA-treated patients were AMH and AFC.Our species has the peculiar ability to accumulate cultural innovations over multiple generations, a phenomenon termed 'cumulative cultural evolution' (CCE). Recent years have seen a proliferation of empirical and theoretical work exploring the interplay between demography and CCE. This has generated intense discussion about whether demographic models can help explain historical patterns of cultural changes. Here, we synthesize empirical and theoretical studies from multiple fields to highlight how both population size and structure can shape the pool of cultural information that individuals can build upon to innovate, present the potential pathways through which humans' unique social structure might promote CCE, and discuss whether humans' social networks might partly result from selection pressures linked to our extensive reliance on culturally accumulated knowledge.The current COVID-19 pandemic has rendered up to 15% of patients under mechanical ventilation. Because the subsequent tracheotomy is a frequent procedure, the three societies mostly involved (SEMICYUC, SEDAR and SEORL-CCC) have setup a consensus paper that offers an overview about indications and contraindications of tracheotomy, be it by puncture or open, clarifying its respective advantages and enumerating the ideal conditions under which they should be performed, as well as the necessary steps. Regular and emergency situations are displayed together with the postoperative measures.The bacterial cell envelope plays essential roles in controlling cell shape, division, pathogenicity, and resistance against external stresses. In Escherichia coli, peptidoglycan (PG) has long been thought to be the primary component that conveys mechanical strength to the envelope. But a recent publication demonstrates the key contribution of the lipoprotein Lpp in defining the stiffness of the cell envelope and its sensitivity to drugs.Background Pemphigus vulgaris (PV) is an uncommon, serious disease that is treated with systemic corticosteroids and corticosteroid-sparing agents. Objectives To describe and analyze the demographic and clinical characteristics of patients with PV. Material and methods Retrospective cohort study of adults diagnosed with PV over a period of 12years. Results PV presented with mucosal lesions in 20 of the 32 patients studied (63%); the most common site was the oral mucosa followed by the vulva. Mucosal involvement was more common in women (P=.03). Lesions were found at more than 1 mucosal site in patients whose disease began in the mucosa, independently of age or sex (P=.003). Disease onset before the age of 40years was associated with generalized skin lesions (P=.003), a need for corticosteroid-sparing therapy (P=.05), and refractory PV (P=.02). MI-773 Azathioprine was the most widely prescribed corticosteroid-sparing agent (in 22 patients). Eight patients (25%) were dependent on corticosteroids and disease recurred in 26 (81%). Complete remission, with or without treatment, was achieved in 15 patients (47%). Patients remained disease-free for a median of 14months, and 2 patients died (6%). Conclusion Onset before the age of 40 years could be a sign of poor prognosis in patients with PV, as it was significantly associated with a higher risk of generalized skin involvement, a need for corticosteroid-sparing therapy, and refractory disease.Background Maxillary sinus fungal ball is a common cause of unilateral maxillary sinusitis. Fungal balls or mycetomas are primarily treated with surgery to remove the fungus. However, this assumes the pre-fungal ball sinus cavity was normal and post-surgery patients may suffer from mucostasis in the sinus cavity with persistent symptoms. It is proposed that fungal balls are potentially a feature of impaired mucus clearance as they are a pathology in their own right. Methods A case series of consecutive patients undergoing antrostomy for maxillary sinus fungal ball was performed. Patient factors including age, gender, smoking status, comorbidities (allergy, asthma, and reflux), disease specific factors including duration of symptoms, microbiology (bacterial co-infection, Gram-positive and/or Gram-negative) and preoperative radiologic findings (extent of sinus development, and neo-osteogenesis/bone thickness) were collected. The primary outcome was sinus function defined by evidence of a normal functioning maxillary sinus, with the absence of mucostasis or pooling, on endoscopic exam at three months, six months and last follow-up. Endoscopic evaluation of inflammation was also collected. Results 28 patients (age 58.5 ± 15.5 years, 64.3% female) were assessed. Mucostasis was present at three months in 39.3%, at six months in 32.1%, and 17.9% at last follow-up. There was no comorbidity or radiologic finding that was associated with failure to normalize. Those patients with mucostasis had a higher modified Lund-Mackay endoscopic score at last follow-up (5.0 ± 0.7 v 0.2 ± 0.6, p less then 0.01). Conclusions Long term post-operative mucostasis occurred in 17.9% of patients following an adequate maxillary antrostomy for treatment of a fungal ball. Patients with mucostasis had persistent mucosal inflammation and a greater need for further surgery (modified medial maxillectomy).
