Viridans streptococcal (Streptococcus intermedius) mitral valve subacute bacterial endocarditis (SBE) in a patient with mitral valve prolapse after a dental procedure: the importance of antibiotic prophylaxis.

BACKGROUND: Subacute bacterial endocarditis (SBE) is an infection of the heart involving damaged valves or endothelium. The most common organisms causing SBE are the viridans streptococci. Viridans streptococci differ in their propensity to cause SBE, which is related to the ability to adhere to damaged heart valves and endothelium, which is a function of extracellular matrix production. Streptococcus intermedius is a member of the S. anginosus group. S. intermedius is one of the many strains of viridans streptococci and a rare cause of SBE. SBE may result following a high-grade, sustained ver

Adjuvant A-PRF Application in Patients with Various Stages of Medication-Related Osteonecrosis of the Jaw (MRONJ): Case Series.

Background and Clinical Significance: Medication-related osteonecrosis of the jaw (MRONJ) is a severe complication of antiresorptive therapies such as Zolendronic acid, used for bone metastases. Its management remains challenging, with outcomes often unpredictable. Platelet-rich fibrin (PRF), rich in growth factors, has been proposed as a potential adjunct to surgical treatment, aiming to promote tissue regeneration and improve patient outcomes. Case Presentation: We reported three clinical cases of MRONJ in patients previously treated with Zolendronic acid. All patients underwent surgical seq

Bacterial Involvement in Progression and Metastasis of Adenocarcinoma of the Stomach.

Gastric cancer metastasis is a process in which the tumor microenvironment may carry significant influence. Helicobacter pylori (H. pylori) infection is well-established as a contributor to gastric carcinoma. However, the role that these bacteria and others may play in gastric carcinoma metastasis is a current focus of study. A review of the literature was conducted to elucidate the process by which gastric adenocarcinoma metastasizes, including its ability to utilize both the lymphatic system and the venous system to disseminate. Studies that investigate the tumor microenvironment at both the

Survival with optimal medical management in a cohort of severe necrotizing bacterial lung infections.

BACKGROUND: Necrotizing pneumonia and lung gangrene represent a continuum of severe lung infection. Traditionally, severe cases have been referred for surgical debridement. However, this has been linked to high mortality. Some groups have published encouraging results using a conservative medical approach. Unfortunately, lack of a standardized definition of necrotizing pneumonia has precluded meaningful comparison between medical and surgical approach in severe cases. Our objective was to describe the outcome of a cohort of severe necrotizing pneumonia treated with optimal medical management.

Role of Actinomyces spp. and related organisms in the development of medication-related osteonecrosis of the jaw (MRONJ): Clinical evidence based on a case series.

Medication-related osteonecrosis of the jaw (MRONJ) is an increasingly common consequence of antiresorptive treatment, which often leads to the development of necrotic exposed bone surfaces with inflammatory processes affecting the jawbone. Although the development of MRONJ is often associated with the inflammatory response or infections caused by the colonizing members of the oral microbiota, the exact pathogenesis of MRONJ is still not fully understood. In the present paper, we aimed to provide additional, microbiological culture-supported evidence, supporting the "infection hypothesis" that

Gut microbiota shapes cancer immunotherapy responses.

The gut microbiota significantly influences cancer immunotherapy efficacy by modulating immune responses, remodeling the tumor microenvironment (TME), and producing key metabolites. Strategies such as FMT, probiotics, and dietary interventions show promise in enhancing responses to ICIs and ACTs while reducing immune-related adverse events (irAEs). This review summarizes clinical and preclinical findings and discusses microbiota-based interventions and future directions for precision immunotherapy.

Treatment of Medication-Related Osteonecrosis of the Jaw Without and With the Use of Advanced Platelet-Rich Fibrin: A Retrospective Clinical Study.

BACKGROUND: Medication-related osteonecrosis of the jaw (MRONJ) is drug-induced bone destruction that is exposed for a minimum of 6 to 8 weeks in patients who have not received head and neck radiotherapy and who have not been diagnosed with facial bone metastases. MRONJ treatment outcomes are unpredictable. Therefore, alternative treatment methods are being explored, such as blood-derived platelet-rich preparations enriched with growth factors, including advanced platelet-rich fibrin (A-PRF). The presence of growth factors may enhance healing and reduce post-procedure complications. There are

The impact of the gut microbiome on tumor immunotherapy: from mechanism to application strategies.

Immunotherapy is one of the fastest developing areas in the field of oncology. Many immunological treatment strategies for refractory tumors have been approved and marketed. Nevertheless, much clinical and preclinical experimental evidence has shown that the efficacy of immunotherapy in tumor treatment varies markedly among individuals. The commensal microbiome mainly colonizes the intestinal lumen in humans, is affected by a variety of factors and exhibits individual variation. Moreover, the gut is considered the largest immune organ of the body due to its influence on the immune system. In t

The Molecular Basis and Clinical Consequences of Chronic Inflammation in Prostatic Diseases: Prostatitis, Benign Prostatic Hyperplasia, and Prostate Cancer.

Chronic inflammation is now recognized as one of the major risk factors and molecular hallmarks of chronic prostatitis, benign prostatic hyperplasia (BPH), and prostate tumorigenesis. However, the molecular mechanisms by which chronic inflammation signaling contributes to the pathogenesis of these prostate diseases are poorly understood. Previous efforts to therapeutically target the upstream (e.g., TLRs and IL1-Rs) and downstream (e.g., NF-κB subunits and cytokines) inflammatory signaling molecules in people with these conditions have been clinically ambiguous and unsatisfactory, hence foster
