In order to implement the knowledge of cancer to monitor its evolution and setting, in the last decade, new minimally invasive and repeatable samples collection have been developed such as liquid biopsy. Cancer biomarkers originating from tumors can represent the molecular status of the tumor or its metastases which release them directly into body fluids or indirectly due to disruption of tumor/metastatic tissue. These biomarkers are detectable in liquid biopsy.

There are many exciting developments in the field of midlife women’s health which explain how menopause symptoms, particularly hot flashes, may be an important vital sign and predictor of future health status. Additionally, in the therapeutic realm, there is a new class of medications that affect the thermoregulatory channels in the brain that control vasomotor symptoms (VMS). This development may unlock treatment options for women who cannot tolerate or cannot safely take hormone therapy.

A national perinatal survey in France in 2016 showed that 12.2% of women have instrumentally assisted vaginal births with vacuum extraction used in 49.8% of cases, making it the most frequently used form of obstetrical assistance. The 2006 initial concept of the Icup^® vacuum extractor was based on the development of a single-use device with a partially deformable cup to avoid any fetal scalp injury. 

Advanced ultrasound offers an important diagnostic clinical tool for the specialty of Obstetrics (OB) and Gynecology (GYN). The advanced ultrasound technologies, such as power Doppler angiography, with its assessment of vascular flow, adds to the described clinical benefits. The imaging technology that this represents, offers diagnostic abilities for a variety of obstetric and gynecologic conditions

Cancer is a worldwide public health issue that affects millions of people every year. In 2018 there were 17 million newly documented cases of cancer globally (8.8 million in men and 8.2 million in women), leading to 9.6 million deaths. Cancer is a vastly heterogeneous disease, with over 100 different types of cancer currently identified in humans; the most common types of cancer are lung, female breast, bowel and prostate, these four types account for more than 40% of all new cancer case

Breast Cancer is the most regularly diagnosed type of cancer in women in the world, making up on its own 25% of all cases, or nearly 2 million new cases in 2018, and 15% of all cancer related deaths, or around 626,700 deaths for that same year.

The published study Compliance and health consequences of menopausal hormonal therapy after surgical menopause: A retrospective study in Thailand showed that menopausal hormonal therapy soon after bilateral oophorectomy before the age of natural menopause in Thailand possibly prevented subsequent osteopenia compared with menopausal hormonal therapy non-users, also without significant adverse breast outcomes comparing between hormonal therapy users and non-users.

Immune thrombocytopenia is an autoimmune disease predominantly caused by autoantibody mediated platelet and megakaryocyte destruction and or dysfunction, which leads to low platelet counts and risk of bleeding. Currently prognostic biomarkers are underdeveloped and there lacks a gold-standard for therapeutics, which leaves an inexplicable refractory subset of patients which are clinically challenging.

Postmenopausal hyperhidrosis (PMH) is an important differential diagnosis to vasomotor symptoms (VMS) in menopause. The objective is to describe the differences in clinical presentation and treatment of the two conditions. Patients suffering from PMH represent a unique cohort of patients with primary hyperhidrosis and should therefore not be treated in the same way as those displaying VMS during menopause.

How medications whose major biologic effect is to reduce bile acid synthesis favorably affect the course of a variety of cholestatic and metabolic liver diseases is not immediately apparent. Also, the most frequently used plasma biomarkers for evaluating benefit, alkaline phosphatase and conjugated bilirubin [1], provide different information. The former may be misleading with respect to the course of the disease and therefore it is important to focus on the pathophysiologic basis for its use.

Lung cancer is the leading cause of cancer death worldwide. In 2020, a total of 19 million cancer patients were diagnosed, of which 11.4% were lung cancer, causing 18% of all cancer deaths. In 2020 in Spain, 29,638 cases were estimated.

Improving our knowledge regarding the cellular and molecular mechanisms underlying murine models of alcoholic liver injury should enhance the management and therapies of alcoholic liver disease (ALD) seen in humans [1]. Although none of the animal models available reproduce all main aspects of human ALD, they still provide very

The proteasome system in the cell degrades the majority of intracellular proteins. The broad nature of its substrates makes proteasome activity crucial for many cellular functions, such as protein quality control, transcription, apoptosis, immune responses, cell signaling and differentiation. The proteasome system is thus an effective therapeutic target for malignant and non-malignant diseases.

Ovarian cancer affects 15 women per 100,000 in Europe [1] but it is not one disease. Epithelial malignancy the most common type of ovarian malignancy and defines the groups termed carcinoma [2,3]. Other malignant subtypes include sarcomas, germ cell tumors and sex-cord stromal tumors [1]. Ovarian carcinomas are subdivided based on histological features, the most common being high-grade serous carcinoma which makes up around 70% of ovarian carcinomas [2,4]. Up to 10% of ovarian carcinomas are endometrioid subtype, having phenotypic and molecular resemblances to endometroid adenocarcinomas that arise in the endometrial cavity [3,5] Clear cell carcinoma (OCCC) and endometrioid carcinoma of the ovary (EnOC) occur on a background of ovarian endometriosis in as many as 70% of cases [6,7]. OCCC is equally as common as endometroid type, perhaps reflecting this shared origin and collectively are often referred to as Endometriosis-Associated Ovarian Carcinomas (EAOCs). Mucinous carcinoma is less common than endometriosisrelated carcinomas at around 3% of ovarian carcinomas [2].

Similar to other African countries, life expectancy of people living with HIV infection has improved due to access to antiretroviral therapy (ART) in Rwanda. However, both HIV infection and use of ART are associated with cardiovascular disease (CVD) risks, due to adverse changes in some biomarkers, causing dyslipidemia and other metabolic imbalances. Biomarkers for CVD risk in HIV-infected individuals taking ART, has not been well characterized in Rwanda.

Neuromyelitis Optica (NMO) is a serious condition associated with inflammation. Early diagnosis and detection are critical for early intervention. In this systematic review, we investigate the role of the neutrophil to lymphocyte ratio (NLR) as an important biomarker for NMO.

Artificial Intelligence (AI) has been the subject of many contributions to the lay and professional literature in the past few years. While it may seem that the medical benefits of its use are immense, there may be reasons to consider a degree of caution in this regard. In particular, the clinical value of using algorithms to predict disease should be measured against the cases in which such algorithms are not used. Then, the resultant costs can be measured to show possible clinical benefit of AI. 

Early-stage NSCLC, encompassing resectable stage I-III  are curable, and represents 25% of all lung cancers. The management of non-metastatic NSCLC is a rapidly changing area of clinical oncology, where utilization of molecular biomarkers has become a cornerstone in informing appropriate management. In current clinical practice, adjuvant chemotherapy is recommended after surgical resection for tumors ≥ 4 cms in size (AJCC 7th stage IB, AJCC 8th stage IIA, and higher stage groups thereafter).

Introduction: Resolvin D2 (RvD2), a mediator that helps resolve inflammation, plays a role in stopping the progression of atherosclerotic cardiovascular disease (ASCVD). Understanding how RvD2 levels relate to ASCVD risk could reveal its potential as both a treatment target and a biomarker. Methods: We examined the research by Liu et al., which used an analytical method that combined restricted cubic splines with multivariable Cox proportional hazard models. 

A decade ago, Science magazine named cancer immunotherapy as the breakthrough of the year, recognizing its pivotal clinical trials of antibodies designed to inhibit negative regulators of T cell function. Antibody therapies targeting cytotoxic T lymphocyte antigen 4 (CTLA-4) and programmed cell protein 1 (PD-1) initially showed effectiveness against advanced melanoma and have since expanded in use to non-small cell lung, renal cell, and bladder cancers, among others.
