Type 2 diabetes mellitus (T2DM) is significantly associated with oxidative stress, resulting from the imbalance between reactive oxygen species (ROS) production and antioxidant defenses. This imbalance contributes to insulin resistance, β-cell dysfunction, and complications in organs like the vasculature and nervous system. Glutathione (GSH), a major antioxidant, is crucial for neutralizing ROS, but GSH levels are notably low in T2DM, exacerbating oxidative stress and inflammation. Elevated interleukin-6 (IL-6) levels further intensify inflammation and oxidative stress, disrupting insulin signaling and worsening complications such as nephropathy, retinopathy, and neuropathy. While lifestyle modifications and antioxidant supplementation are current approaches for managing oxidative stress, their effectiveness in preventing complications remains under study. Recent investigations suggest that GSH and Vitamin D3 supplementation may offer dual-action benefits, as Vitamin D3 not only has anti-inflammatory properties but also promotes GSH synthesis. This dual action helps mitigate both oxidative stress and inflammation, addressing key pathological features of T2DM. This review highlights the complex interactions between oxidative stress, GSH insufficiency, and IL-6, and emphasizes the potential of targeted therapies to improve the management and outcomes of T2DM.

Tuberculosis (TB) caused by Mycobacterium tuberculosis (M.tb) remains a global health crisis, with over 10 million people affected annually. Despite advancements in treatment, M.tb has developed mechanisms to evade host immune responses, complicating efforts to eradicate the disease. Two emerging cell death pathways, ferroptosis and cuproptosis, have been linked to TB pathogenesis. Ferroptosis, an iron-dependent form of cell death, is driven by lipid peroxidation and reactive oxygen species (ROS) accumulation. This process can limit M.tb replication by depleting intracellular iron and inducing macrophage necrosis. However, excessive ferroptosis may lead to tissue damage and aid bacterial dissemination. Cuproptosis, triggered by copper accumulation, disrupts mitochondrial metabolism, leading to protein aggregation and cell death. M.tb exploits both iron and copper metabolism to survive within macrophages, manipulating these processes to resist oxidative stress and immune responses. This review examines the roles of ferroptosis and cuproptosis in TB, discussing how M.tb manipulates these pathways for survival. While therapeutic strategies targeting these processes, such as ferroptosis inducers (Erastin, RSL3) and inhibitors (Ferrostatin-1) and copper ionophores (Disulfiram, Elesclomol) and chelators, show promise, the limited understanding of these pathways and potential off-target effects remains a significant challenge. Further exploration of these pathways may provide insights into the development of targeted therapies aimed at controlling M.tb infection while minimizing host tissue damage. By elucidating the complex interactions between ferroptosis, cuproptosis, and TB, future therapies could better address bacterial resistance and improve clinical outcomes.

May–Thurner syndrome (MTS) is a developmental anatomical variant in which the right common iliac artery compresses the left common iliac vein against the underlying lumbar vertebral body. This compression leads to endothelial injury, venous stasis, and progressive luminal narrowing, significantly increasing the risk of left-sided iliofemoral deep vein thrombosis (DVT). Combined oral contraceptives containing ethinyl estradiol are known to increase the risk of DVT, particularly during the initial months of use or during dose changes, with thrombotic risk persisting for up to 10 to 12 weeks after discontinuation. We present the case of a 34-year-old previously healthy female with no significant past medical history who presented with left leg swelling and lower abdominal discomfort. She had intermittently used a combined estrogen-containing oral contraceptive pill, discontinued 2 weeks prior to presentation. Imaging confirmed extensive DVT, and computed tomography venography revealed classic features of MTS, with compression of the left common iliac vein by the right common iliac artery. This case underscores the importance of evaluating structural etiologies in young patients and emphasizes the synergistic risk between hormonal and anatomical factors in precipitating a DVT. Timely diagnosis and targeted management were essential to achieving a favorable outcome.

Latent autoimmune diabetes in adults (LADA) combines features of type 1 and type 2 diabetes, characterized by autoantibodies and progression to insulin dependence. Glutamic acid decarboxylase antibody is more prevalent in White populations and also prevalent to a lesser degree in Asian populations, while insulinoma-associated protein 2 (IA-2) antibodies are much less frequent in Asian populations. The objective of this report is to emphasize diagnostic reconsideration in cases of diabetes that present with atypical phenotypic or ethnic features, highlighting the value of comprehensive autoantibody testing. A 56-year-old Japanese-American male with a history of diabetes mellitus, deep vein thrombosis, hypokalemia, and hypophosphatemia presented with hyperglycemia and fatigue. Laboratory evaluation revealed glucose 262 mg/dL (reference 70–99), glycated hemoglobin 11.6% (reference <5.7%), arterial pH 7.07 (reference 7.35–7.45), bicarbonate 2.7 mmol/L (reference 22–28), potassium 2.7 mmol/L (reference 3.5–5.0), and phosphate 0.8 mg/dL (reference 2.5–4.5). Autoimmune testing revealed IA-2 antibody positivity. He was treated with standard diabetic ketoacidosis protocol, transitioned to subcutaneous insulin, and discharged with diabetic education. LADA involves gradual autoimmune-mediated beta-cell destruction. IA-2 positivity, while less common in Asian populations, is linked to more rapid beta-cell decline. Early insulin initiation is essential. This case emphasizes the importance of considering ethnicity gender, age, and body mass index in diagnostic evaluations. This case highlights the importance of distinguishing LADA from type 2 diabetes in patients with atypical clinical features and emphasizes how antibody status and factors such as age, sex, and body mass index can influence diagnostic accuracy.

Empyema is a complication of pneumonia, characterized by pus accumulation in the pleural space. It is more common in patients with comorbidities such as older age, diabetes, cancer, or immunocompromised states. Aspiration or oral cavity infections are more common in older adults with significant risk factors; therefore, the pathogen Streptococcus constellatus is usually rare. S. constellatus is mainly known for its ability to produce abscesses and pyogenic invasive infections, with most of the infections being found in the orofacial and gastrointestinal regions. The patient is a 58-year-old female who presented with weakness, fatigue, nausea, anorexia, diarrhea, and subjective fever for two weeks. Investigation revealed that there was left-sided empyema, and the pleural fluid grew S. constellatus on culture. The management included antibiotics, chest tube drainage, and finally decortication. The patient’s recovery further demonstrates how rare and complex empyema caused by S. constellatus is in a healthy person.
