CD133 as a Functional Unit in Glioblastoma
Biomarkers for resistance in Glioblastoma multiforme (GBM) are lacking, and progress in the clinic has been slow to arrive. CD133 (prominin-1) is a membrane-bound glycoprotein on the surface of cancer stem cells (CSCs) that has been associated with poor prognosis, therapy resistance, and tumor recurrence in GBM. Due to its connection to CSCs, to which tumor resistance and recurrence have been partially attributed in GBM, there is a growing field of research revolving around the potential role of CD133 in each of these processes. However, despite encouraging results in vitro and in vivo, the biological interplay of CD133 with these components is still unclear, causing a lack of clinical application. In parallel, omic data from biospecimens that include CD133 are beginning to emerge, increasing the importance of understanding CD133 for the effective use of these highly dimensional data sets. Given the significant mechanistic overlap, prioritization of the most robust findings is necessary to optimize the transition of CD133 to clinical applications using patient-derived biospecimens.

Cardiovascular Disease Outcomes Associated with OSA in Diabetics
There is significant pathogenic and epidemiological overlap between diabetes and obstructive sleep apnea (OSA).  There may be a possible association between OSA and diabetes and their impact on cardiovascular diseases (CVDs). Identifying and managing OSA in individuals with diabetes at an early phase could potentially reduce the risk of CVDs and its related complications.

Systemic Treatment Strategies in Early HER2-Positive Breast Cancer
HER2-positive breast cancer (BC) is associated with an aggressive clinicopathological nature and is known to have a poor prognosis. Their tumor proliferation features can lead to visceral metastasis disseminating to the brain, liver, lung, and bone. Delivering standard chemotherapy HER2 blockers is strongly associated with better outcomes and can help increase the suitability for breast-conserving surgery. It is crucial to identify patients who should be selected for systemic cancer treatment before or after surgery and to decide the most appropriate option in each case.

PARP Inhibitors in Ovarian Cancer
Poly (ADP-ribose) polymerase (PARP) inhibitors are a novel class of therapeutic agents that target tumors with deficiencies in the homologous recombination DNA repair pathway. Genomic instability characterizes high-grade serous ovarian cancer (HGSOC), with one half of all tumors displaying defects in the important DNA repair pathway of homologous recombination. Early studies have shown significant efficacy for PARP inhibitors in patients with germline breast related cancer antigens 1 and 2 (BRCA1/2) mutations. It has also become evident that BRCA wild-type patients with other defects in the homologous recombination repair pathway benefit from this treatment. Companion homologous recombination deficiency (HRD) scores are being developed to guide the selection of patients that are most likely to benefit from PARP inhibition. The choice of which PARP inhibitor is mainly based upon the number of prior therapies and the presence of a BRCA mutation or HRD. The identification of patients most likely to benefit from PARP inhibitor therapy in view of HRD and other biomarker assessments is still challenging. The aim of this review is to describe the current evidence for PARP inhibitors in ovarian cancer, their mechanism of action, and the outstanding issues, including the rate of long-term toxicities and the evolution of resistance.

Ankle Arthropathy in Hereditary Hemochromatosis
Hereditary hemochromatosis (HH) is an autosomal recessive bleeding disorder characterized by tissue overload of iron. Clinical systemic manifestations in HH include liver disease, cardiomyopathy, skin pigmentation, diabetes mellitus, erectile dysfunction, hypothyroidism, and arthropathy. Arthropathy with joint pain is frequently reported at diagnosis and mainly involves the metacarpophalangeal and ankle joints, and more rarely, the hip and knee. Symptoms in ankle joints are in most cases non-specific, and they can range from pain and swelling of the ankle to deformities and joint destruction. Furthermore, the main radiological signs do not differ from those of primary osteoarthritis (OA). Limited data are available in the literature regarding treatment; surgery seems to be the gold standard for ankle arthropathy in HH.

Obesity and Selected Allergic and Immunological Diseases
Obesity is a global problem. It affects every age group and is associated with many negative health effects. As an example, there is a relationship between obesity and allergic and immunological diseases, such as asthma, psoriasis, food allergies, allergic rhinitis and atopic dermatitis. Obesity undeniably affects their development.

Achieving Optimum Clinical Outcomes with Vitamin D
Musculoskeletal benefits of vitamin D include calcium homeostasis, bone mineralization, etc., through its hormonal actions. This requires serum 25(OH)D less than 20 ng/mL. In contrast, many other tissues require above 30 or 40 ng/mL steady-state concentrations. To reduce infections, autoimmune diseases, cancer, and all-cause mortality require a minimum level of 50 ng/mL. Vitamin D is an economical and widely available (generic) nutrient obtained over the counter without a prescription. At the recommended doses, vitamin D does not cause any adverse effects. Disease prevention and minimizing complications and premature deaths can be achieved by maintaining serum 25(OH)D concentrations between 50 and 80 ng/mL. This costs less than 0.01% of the cost of one day of hospitalization.

Cellular Defense System for Ferroptosis
Parkinson’s disease (PD) and Alzheimer’s disease (AD) are the most common rapidly developing neurodegenerative diseases that lead to serious health and socio-economic consequences. Ferroptosis is a non-apoptotic form of cell death; there is growing evidence to support the notion that ferroptosis is involved in a variety of pathophysiological contexts, and there is increasing interest in the role of ferroptosis in PD and AD. Simultaneously, cells may have evolved four defense systems to counteract the toxic effects of ferroptosis occasioned by lipid peroxidation.

Clinical Applications of Crystalloids within Enhanced Recovery Pathways
Perioperative fluid management, a critical aspect of major surgeries, is characterized by pronounced stress responses, altered capillary permeability, and significant fluid shifts. Recognized as a cornerstone of enhanced recovery protocols, effective perioperative fluid management is crucial for optimizing patient recovery and preventing postoperative complications, especially in high-risk patients. The scientific literature has extensively investigated various fluid infusion regimens, but publications indicate that not only the volume but also the type of fluid infused significantly influences surgical outcomes.
