Introduction: The conventional in vitro fertilization and the intracytoplasmic sperm microinjection are currently the established techniques for the treatment of infertility. In the last decade, however, the process of in vitro fertilization has suffered several changes in ovulation induction and oocyte retrieval (Ranoux 1990, ; ).The INVO procedure has been used to treat patients with different causes of infertility in many countries. This is a procedure which was developed over 20 years ago and is simpler and less costly to the infertility treatment when compared to conventional techniques. Interesting finding of this intravaginal culture technique are the physiological benefits and the reduction of the number of handling steps, reducing the risk of contamination.
Objective: This study aimed to evaluate the possibility of including the method INVO through the use of the deviceINVOCell™ in routine laboratory treatments of couple infertility. That, in turn, tends to provide the simplification of laboratory work and thereby reduce the costs of infertility treatment.
Material And Methods: 40 women were included in this study, who were treated at the Service of Human Reproduction School Hospital Álvaro Alvim, in the period from August 2011 to January 2012. On all of them it was used the protocol of modified mild ovarian stimulation. The number of pre-embryos transferred into the uterine cavity followed the CFM Resolution nº. 1.957/10.
Results And Conclusion: There was no significant difference in the results presented by the device INVOCell™. Therefore showing that it can be included in routine laboratory assisted human reproduction.

Diagnosing iron deficiency: Controversies and novel metrics.

Division of Clinical Haematology, Department of Medicine, University of Cape Town and Groote Schuur Hospital, Cape Town, South Africa.
Iron deficiency, a pervasive global health issue, necessitates precise and reliable diagnostic methods, especially in clinical and surgical settings. This review examines an array of established markers of iron status, encapsulating parameters such as serum iron, ferritin, transferrin, and transferrin saturation alongside novel biomarkers like soluble transferrin receptor, zinc protoporphyrin, and hepcidin. We further scrutinise the potential and limitations of routine and novel diagnostic tools and strategies in distinguishing different anaemic conditions, such as iron deficiency anaemia, iron-restricted erythropoiesis, and anaemia of inflammation.

Purpose: Acute fatty liver of pregnancy (AFLP) is a severe complication that can occur in the third trimester or immediately postpartum, characterized by rapid hepatic failure. This study aims to explore the changes in portal vein blood flow velocity and liver function during pregnancy, which may assist in the early diagnosis and management of AFLP.
Methods: This longitudinal study was conducted at a tertiary healthcare center with participants recruited from routine antenatal check-ups.

Background Multiple sclerosis is a chronic, progressive, disabling disease associated with a high rate of infection, evidence of chronic inflammation, and a high mortality rate. Abnormalities of serum cytokines and changes in the activity of inflammatory cells were associated with relapsing-remitting multiple sclerosis (MS-RR). This study aims to introduce new inflammatory ratios derived from hematological and lipid indices as discriminators of T-helper (Th)-1/Th-2 activity in RR-MS.

Thanks to the identification of crucial molecular pathways, the therapeutic landscape for advanced differentiated thyroid tumors (DTCs) has significantly improved during the last ten years. The therapeutic scenario has been greatly impacted by the discovery of mutually exclusive gene changes in the MAPK and PI3K/AKT pathways, such as or fusions and pathogenic mutations of the and genes. Indeed, multi-kinase inhibitors and selective inhibitors have demonstrated outstanding efficacy for radioactive iodine-refractory (RAI-R) drug treatment, with overall response rates reaching up to 86%.
