The Role of the Complement System in HUS
Hemolytic uremic syndrome (HUS) is an acute disease and the most common cause of childhood acute renal failure. HUS is characterized by a triad of symptoms: microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury. In most of the cases, HUS occurs as a result of infection caused by Shiga toxin-producing microbes: hemorrhagic Escherichia coli and Shigella dysenteriae type 1. They account for up to 90% of all cases of HUS. The remaining 10% of cases grouped under the general term atypical HUS represent a heterogeneous group of diseases with similar clinical signs. Emerging evidence suggests that in addition to E. coli and S. dysenteriae type 1, a variety of bacterial and viral infections can cause the development of HUS. In particular, infectious diseases act as the main cause of aHUS recurrence. The pathogenesis of most cases of atypical HUS is based on congenital or acquired defects of complement system.

Androgen Receptor’s Role in Triple Negative Breast CancerBC
Triple negative breast cancer (TNBC) comprises 10–20% of diagnosed breast cancers. TNBCs are devoid of common biomarkers such as an estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). Research is being conducted to determine the androgen receptor’s (AR) role in TNBC and determine its ability to be utilized as an effective drug target in the absence of the commonly targeted receptors.

Ten Issues for Updating in Community-Acquired Pneumonia
Community-acquired pneumonia represents the third-highest cause of mortality in industrialized countries and the first due to infection. Although guidelines for the approach to this infection model are widely implemented in international health schemes, information continually emerges that generates controversy or requires updating its management.

Dysuricemia on the Path toward Normouricemia
The disease concept of “dysuricemia” includes hyperuricemia and hypouricemia. Both influence diseases in humans. Uric acid plays dual roles in oxidative stress: it has both an anti-oxidative protective effect and a pro-oxidative and/or a harmful crystal-forming effect. Extensive research on the relationship between the serum urate (SU) level and several common disease risks show characteristic patterns that are broadly classifiable into three patterns: the “gout pattern,” “neurodegenerative disease (ND) pattern,” and “chronic kidney disease (CKD) and cardiovascular disease (CVD) pattern”. In short, “the lower, the better” is incorrect; the ideal is to maintain normouricemia, or an optimal SU level, to reduce the risks of the common diseases associated with dysuricemia.

Characteristics and Treatment of Elderly-Onset Rheumatoid Arthritis
Elderly-onset rheumatoid arthritis (EORA) is a distinct clinical entity defined as the onset of rheumatoid arthritis (RA) in individuals aged over 60 years. EORA presents unique clinical features, including a more equitable distribution of sexes, a potential predilection for male involvement, a higher incidence of acute onset characterized by constitutional symptoms, a propensity for systemic manifestations, elevated sedimentation rates at disease onset, a reduced occurrence of rheumatoid factor positivity, increased titers of anti-citrullinated protein antibodies, a preference for involvement of large joints, elevated disease activity, the presence of bone erosions, and heightened patient disability.

Japanese Cedar (
Cryptomeria japonica
D. Don) Pollen Information
About 40% of cedar pollinosis patients living in the Yamagata Prefecture showed pollinosis symptoms before the first day of the pollen season, which was determined by Durham samplers, the standard sampler for pollen information in Japan. The amount of Cry j 1 (major cedar pollen allergen) per cedar pollen is reported to be six pg. This amount is difficult to measure using the ELISA method. It revealed that Cry j 1 exists in orbicles and tapetum. It is presumed that it is smaller than pollen, so it comes from a place where cedar are already in bloom. It is desirable to obtain real-time information on an hourly basis. Currently, information from automatic cedar pollen monitors is becoming main-stream. However, this monitor may count during snowfalls, Asian dust flying, etc., even when there was no apparent pollen examined with a microscope.

Cardiac Magnetic Resonance (CMR) Mapping
Cardiac magnetic resonance (CMR) imaging has witnessed substantial progress with the advent of parametric mapping techniques, most notably T1 and T2 mapping. These advanced techniques provide valuable insights into a wide range of cardiac conditions, including ischemic heart disease, cardiomyopathies, inflammatory cardiomyopathies, heart valve disease, and athlete’s heart. Mapping could be the first sign of myocardial injury and oftentimes precedes symptoms, changes in ejection fraction, and irreversible myocardial remodeling. The ability of parametric mapping to offer a quantitative assessment of myocardial tissue properties addresses the limitations of conventional CMR methods, which often rely on qualitative or semiquantitative data. However, challenges persist, especially in terms of standardization and reference value establishment, hindering the wider clinical adoption of parametric mapping. Future developments should prioritize the standardization of techniques to enhance their clinical applicability, ultimately optimizing patient care pathways and outcomes.

Hypothermia
Hypothermia is a widespread condition all over the world, with a high risk of mortality in pre-hospital and in-hospital settings when it is not promptly and adequately treated. Hypothermia can occur due to unfavorable environmental conditions as well as internal causes, such as pathological states that result in reduced heat production, increased heat loss or ineffectiveness of the thermal regulation system. The consequences of hypothermia affect several systems in the body—the cardiovascular system, the central and peripheral nervous systems, the respiratory system, the endocrine system and the gastrointestinal system—but also kidney function, electrolyte balance and coagulation.

Multimodal Ophthalmic Imaging in Spinocerebellar Ataxia Type 7
SCA7, from an ophthalmological point of view, can be assessed through numerous multimodal imaging techniques to evaluate and manage the follow-up of patients. Visual acuity is a fundamental parameter that should be monitored, and spectral domain optical coherence tomography (SDOCT), which is a rapid and non-invasive method, should be routinely performed to evaluate ophthalmic disease progression over time. Additional exams, including NIR imaging, can indicate photoreceptor loss and disruption of the RPE that are not readily evident with color fundus photography (CFP).

Chimeric Antigen Receptor T Cell Therapy in AML
Acute myeloid leukemia (AML) is a heterogeneous hematological malignancy that is often associated with relapse and drug resistance after standard chemotherapy or targeted therapy, particularly in older patients. Hematopoietic stem cell transplants are looked upon as the ultimate salvage option with curative intent. Adoptive cell therapy using chimeric antigen receptors (CAR) has shown promise in B cell malignancies and is being investigated in AML.
