Consciousness transitions during epilepsy seizures through the lens of integrated information theory.

Consciousness is one of the most complex aspects of human experience. Studying the mechanisms involved in the transitions among different levels of consciousness remains as one of the greatest challenges in neuroscience. In this study we use a measure of integrated information (ΦAR) to evaluate dynamic changes during consciousness transitions. We applied the measure to intracranial electroencephalography (SEEG) recordings collected from 6 patients that suffer from refractory epilepsy, taking into account inter-ictal, pre-ictal and ictal periods. We analyzed the dynamical evolution of ΦAR in groups of electrode contacts outside the epileptogenic region and compared it with the Consciousness Seizure Scale (CCS). We show that changes on ΦAR are significantly correlated with changes in the reported states of consciousness.

A targeted GC-MS/MS approach for the determination of eight sterols in microgreen and mature plant material.

Over the past decades, a remarkable number of scientific studies supported the correlation between an adequate dietary intake of phytosterols (PS) and the reduced risk of cardiovascular diseases. PS are known to inhibit the intestinal absorption of cholesterol, thus promoting the reduction of the low-density lipoproteins (LDL) amount in the bloodstream. Despite the fact that a non-negligible atherogenicity was recognized to PS, thus requiring a careful risk-benefits assessment for plant sterol supplementation, the potential role of PS as cholesterol-lowering agents has been contributing to the spreading awareness of the health benefits associated with the consumption of plant-based foods. In recent years, this has been fueling the market of innovative vegetable products, such as microgreens. Surprisingly, the recent literature concerning microgreens exhibited the lack of studies focusing on the characterization of PS. To fill this gap, a validated analytical method based on the hyphenation of gas chromatography and tandem mass spectrometry is proposed here for the quantitative analysis of eight phytosterols, namely ß-sitosterol, campesterol, stigmasterol, brassicasterol, isofucosterol, and cholesterol, lathosterol and lanosterol. The method was exploited for the characterization of the PS content in 10 microgreen crops, i.e., chia, flax, soybean, sunflower, rapeseed, garden cress, catalogna chicory, endive, kale and broccoli raab. Finally, these results were compared to the PS content of mature forms of kale and broccoli raab. A remarkable amount of PS was detected in chia, flax, rapeseed, garden cress, kale, and broccoli raab microgreens. 100 g (wet weight) of these microgreen crops were found to contain from 20 to 30 mg of the investigated PS. Interestingly, in the case of kale and broccoli raab microgreens, the overall PS content was higher than the one measured in the edible parts of the corresponding mature forms. Additionally, a symmetric change of the PS inner profile was observed between the two growth stages of the latter two crops. Here, the overall decrease of the PS sterol content in the mature forms was associated with the increase of the relative amount of ß-sitosterol and campesterol at the expense of minor PS species, such as brassicasterol.

Effective combined treatment in ectopic cervical pregnancy preserving fertility: a case report and literature review.

OBJECTIVE: Cervical ectopic pregnancy (CEP) is a rare obstetric complication but carries the risk of life-threatening maternal hemorrhage. CASE PRESENTATION: A 43-year-old nulliparous woman, presented to the Emergency Room with vaginal bleeding. Initial quantitative serum ß-hCG value was 85,220 mIU/mL. Obstetrical ultrasound demonstrated a single, live pregnancy of approximately 9 weeks' gestation located within the endocervix. After discussing different management options, intramuscular methotrexate injection in association with intra-amniotic chloride potassium installation was decided in order to preserve patient's desire for childbearing. Three months later, the patient was readmitted due to a massive vaginal bleeding. Angiographic uterine artery embolization (UAE) with an absorbable gelatin sponge was performed. After the procedure and two days of hospitalization, no significative bleeding was observed. The clinical course was uneventful, and serum human chorionic gonadotropin decreased immediately. The cervical mass gradually shrank and disappeared a month after UAE. CONCLUSIONS: To preserve fertility in the management of CEP, clinicians could consider a combination of strategies, including UAE. A review of the current literature and possible treatment options for conservative CEP management are analyzed and discussed.

Minilaparotomic incision for haemorrhagic corpus luteum: a case report.

Corpus luteum cyst rupture with consequent hemoperitoneum is a common cause of admission to the emergency room. This condition is frequently misdiagnosed because of overlapping of clinical findings in acute gynecologic diseases. However, an incorrect identification may lead to delay in surgical treatment, which can Romabe a life-threatening condition. Ultrasound (US) is the first technique used for diagnosis that can confirm or dismiss the presence of intraperitoneal fluid. Secondly, the contrast-enhanced computed tomography (CT) is the quickest way to identify the site of active bleeding and to establish the correct management of the clinical condition. Herein, we report a case of a 19-years-old girl with acute abdominal pain correctly identified by diagnostic images and treated with mini-invasive surgery techniques in order to quickly act without clinic and aesthetic sequelae.
