Identifying the Variables for Oncoplastic Reconstruction: Preoperative Assessment Tool for Breast Conserving Treatment.

Background: A wide range of surgical techniques has been described for breast conservation treatment (Oncoplasty) based on breast size and shape, as well as tumor size and location. However, there is a lack of standardization regarding the indications for oncoplastic reconstruction. This study aims to identify the presurgical parameters associated with poor cosmetic outcomes post-breast conserving treatment.

How effective is digital educational content in shaping fertility awareness? An interventional, cross-sectional study.

Purpose: To determine whether exposure to digital educational content affects fertility awareness and attitudes towards fertility preservation treatments?

Methods: A total of 957 women ages 20 to 45 years participated in this internet-based, interventional, cross-sectional study. A questionnaire assessing knowledge of the reproductive span and attitudes towards fertility preservation treatment was completed by these women before and after exposure to online educational content on ovarian reserve and fertility preservation treatments. Responses before and after exposure to the educational content were compared.

Can Gilbert's syndrome mitigate chronic lymphocytic leukemia?

The study links two intriguing observations about chronic lymphocytic leukemia and Gilbert's syndrome - the oxidative stress affecting the former, and the anti-oxidative effects of the latter. Our pilot study showed that compared to the general CLL population, the GS/CLL cohort less commonly required therapy and demonstrated a reduced CLL-related mortality. Our findings prompt a speculation that elevated bilirubin in GS could hypothetically attenuate the oxidative stress thereby exerting a safeguarding effect on leukemia pathogenesis.

GqPCR-stimulated dephosphorylation of AKT is induced by an IGBP1-mediated PP2A switch.

Background: G protein-coupled receptors (GPCRs) usually regulate cellular processes via activation of intracellular signaling pathways. However, we have previously shown that in several cell lines, GqPCRs induce immediate inactivation of the AKT pathway, which leads to JNK-dependent apoptosis. This apoptosis-inducing AKT inactivation is essential for physiological functions of several GqPCRs, including those for PGF2α and GnRH.

Prenatal diagnosis and postnatal outcome of anterior urethral anomalies.

Objectives: Anterior urethral anomalies (AUA) which present as anterior urethral valve, stenosis or atresia, are a rare cause for congenital urinary tract obstruction. We present our AUA prenatal diagnosis case series.

Methods: Fetuses presenting with prenatal findings suggestive for AUA according to postnatal reported clinical and imaging signs (urinary tract dilatation, dilated bladder, enlarged edematous fetal penis, dilatation of the fetal urethra and diverticula) were followed prospectively.

Self-initiated object-location memory in young and older adults.

The present study explored self-initiated object-location memory in ecological contexts, as aspect of memory that is largely absent from the research literature. Young and older adults memorized objects-location associations they selected themselves or object-location associations provided to them, and elaborated on the strategy they used when selecting the locations themselves. Retrieval took place 30 min and 1 month after encoding.

Severe ASIA syndrome associated with lymph node, thoracic, and pulmonary silicone infiltration following breast implant rupture: experience with four cases.

Silicone has been considered biologically inert; thus it has been employed in many medical devices and nowadays is commonly used in plastic surgery for mammary prosthesis. It is well tolerated in most cases. However, autoimmune disorders and siliconomas with granulomatous reactions after silicone implant rupture have been described.

Predicting post-vaccination autoimmunity: who might be at risk?

Vaccinations have been used as an essential tool in the fight against infectious diseases, and succeeded in improving public health. However, adverse effects, including autoimmune conditions may occur following vaccinations (autoimmune/inflammatory syndrome induced by adjuvants--ASIA syndrome). It has been postulated that autoimmunity could be triggered or enhanced by the vaccine immunogen contents, as well as by adjuvants, which are used to increase the immune reaction to the immunogen.

Why is diabetes mellitus a risk factor for contrast-induced nephropathy?

Contrast-induced nephropathy (CIN) remains a leading cause of iatrogenic acute kidney injury, as the usage of contrast media for imaging and intravascular intervention keeps expanding. Diabetes is an important predisposing factor for CIN, particularly in patients with renal functional impairment. Renal hypoxia, combined with the generation of reactive oxygen species, plays a central role in the pathogenesis of CIN, and the diabetic kidney is particularly susceptible to intensified hypoxic and oxidative stress following the administration of contrast media.

Are oncologists accountable only to patients or also to their families? An international perspective.

In most societies, health professionals traditionally carry responsibility only toward their patients. However, this is not the case in all cultures. In the contemporary practice of oncology in Western cultures, there is a shift toward assuming broader responsibility for patients with cancer' families during the illness course, the grieving stage, and in cancer prevention and genetic counseling.

Reactive oxygen species and the pathogenesis of radiocontrast-induced nephropathy.

Experimental findings in vitro and in vivo illustrate enhanced hypoxia and the formation of reactive oxygen species (ROS) within the kidney following the administration of iodinated contrast media, which may play a role in the development of contrast media-induced nephropathy. Clinical studies indeed support this possibility, suggesting a protective effect of ROS scavenging or reduced ROS formation with the administration of N-acetyl cysteine and bicarbonate infusion, respectively. Furthermore, most risk factors, predisposing to contrast-induced nephropathy are prone to enhanced renal parenchymal hypoxia and ROS formation.

Experimental ischemia-reperfusion: biases and myths-the proximal vs. distal hypoxic tubular injury debate revisited.

Although the understanding of processes associated with hypoxic tubular cell injury has remarkably improved, controversies remain regarding the appropriateness of various animal models to the human syndrome of acute kidney injury (AKI). We herein compare available experimental models of hypoxic acute kidney damage, which differ both conceptually and morphologically in the distribution of tubular cell injury. Tubular segment types differ in their capacity to mount hypoxia-adaptive responses, mediated by hypoxia-inducible factors (HIFs), and in cell type-specific molecules shed into the urine, which may serve as early biomarkers for renal damage.

Animal models of renal dysfunction: acute kidney injury.

Background: Acute renal failure (ARF) is a broad clinical entity, encompassing diverse pathophysiologies, with heterogeneous functional and morphological features. In the same fashion, various animal models of ARF differ in their mechanisms, distribution and type of injury, cellular responses and outcome.

Objective: To appraise available animal models of ARF used for the assessment of potential therapeutic interventions, providing their basic pathophysiologies.

Role of protein kinase C in the expression of endothelin converting enzyme-1.

Increased expression of endothelin converting enzyme-1 (ECE-1) is associated with diabetic nephropathy. The molecular mechanisms underlying this association, as yet unknown, possibly involve protein kinase C (PKC) pathways. In the present study, we examined the effects of high glucose and PKC activation on ECE-1 expression in primary human umbilical vein endothelial cells (HUVECs) and in HUVEC line (EA.

Giant cell arteritis: intensity of the initial systemic inflammatory response and the course of the disease.
