Metabolic dysfunction-associated steatotic liver disease (MASLD) is rapidly emerging as a global health crisis, affecting over 30% of the population and demanding urgent attention. This redefined condition, previously known as non-alcoholic fatty liver disease (NAFLD), reflects a deeper understanding of the intricate interplay between metabolic dysfunction and liver health. At the heart of MASLD lies the troubling accumulation of triglycerides (TGs) in hepatocytes, which precipitates insulin resistance and oxidative stress, ultimately leading to more severe forms like metabolic dysfunction-associated steatohepatitis (MASH). Excitingly, recent research has spotlighted the farnesoid X receptor (FXR) as a groundbreaking therapeutic target. FXR not only regulates lipid metabolism but also combats inflammation and insulin resistance, making it a potential game-changer in the fight against MASLD. With only one FDA-approved drug, resmetirom, currently available, the exploration of FXR agonists opens new avenues for innovative treatments that could revolutionize patient care. By harnessing the power of FXR to restore metabolic balance and integrating advanced strategies like lipidomics and fatty acid profiling, we stand on the brink of transforming how we approach MASLD and its associated complications, paving the way for a healthier future. This review delves into the promising role of FXR in combating MASLD and its implications for related metabolic disorders, emphasizing the urgency for advanced strategies to detect and manage this burgeoning epidemic.

The clinical case presented describes a 44-year-old woman with a history of mucinous carcinoma in the right breast, who is diagnosed with a pituitary adenoma. Physical examination revealed signs of acromegaly, such as macroglossia and palmar hyperhidrosis. Hormonal tests were performed and showed elevated levels of insulin-like growth factor type 1 (IGF-1). The patient received GnRH analogues for breast cancer; and started medical treatment with somatostatin analogues for acromegaly, which provided improvement in symptoms. Pituitary bleeding was detected during hormone treatment, which caused the growth of the adenoma, causing it to contact the optic chiasm, although no symptoms of pituitary apoplexy were present. Transsphenoidal endoscopic surgery was performed to remove the adenoma, and the diagnosis of pituitary adenoma was confirmed by pathology. The importance of the evaluation of comorbidities in patients with acromegaly is discussed. Pituitary apoplexy as an uncommon complication of pituitary adenomas, which may be associated with the use of GnRH analogues, is addressed. Pre-surgical medical treatment in acromegaly is also discussed, highlighting the importance of a comprehensive assessment of prognostic factors and appropriate treatment selection to improve clinical outcomes. In conclusion, the importance of a multidisciplinary and personalized approach in the management of patients with GH-producing pituitary adenomas to improve quality of life and clinical outcomes is highlighted.

Type 2 diabetes mellitus (DM) and hypertension (HT) are common major cardiovascular disease (CVD) risk factors. They share common pathophysiological mechanisms and are commonly co-existent. Prevalence of HT is increased among diabetic patients but also DM is more common in hypertensive patients. CVD risk increases multiplicatively in coexistence of HT and DM. Lowering blood pressure (BP) has been shown to be associated with improved morbidity related to both macro- and micro-vascular complications. Although there is debate about target BP levels, in many randomized controlled trials and guidelines a goal of < 130/80 mmHg is advocated in patients with DM, if well tolerated. However, an individualized approach should be cared for depending on risk factors, co-morbidities, and frailty of patients. Lifestyle modifications including weight loss, regular exercise, avoiding smoking and excessive alcohol consumption, and a healthy diet including limitation of salt and fat and total energy intake, are important both as a part of preventive therapy and treatment modality for both DM and HT. Among antihypertensive drugs angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin receptor blockers (ARBs) are warranted due to their potential advantages for slowing albuminuria and progression to kidney failure which is more common in DM. Usually, their combination with calcium-channel blockers (CCBs) or thiazide/thiazide-like diuretics, in a step-wise manner, is recommended. Resistant HT is more common in DM and requires the addition of mineralocorticoid receptor antagonists (MRAs). New antidiabetic drugs like glucagon-like peptide 1 (GLP-1) agonists and sodium-glucose cotransporter 2 (SGLT2) inhibitors have been found to lower BP. Apart from their antihypertensive effects they also improve CVD and renal outcomes. There’re ongoing new trials for new agents. Development of more potent and longer-term effective BP lowering drugs, single pill multiple drug combinations of antiHT agents and combination of antiHT agents with glucose-lowering and antilipidemic agents will probably improve compliance to treatment and achievement of goals in diabetic patients.

A 74-year-old male patient with beta thalassemia minor presented in 2022 for a follow-up of osteoporosis diagnosed prior to 2004. At the time of presentation, his medical history included: radiation exposure to his head and neck, goiter, prostate cancer status post resection in 2019 without a history of anti-androgen therapy, and atrial fibrillation, for which he had been prescribed apixaban since 2021. Treatment with risedronate occurred from approximately 2004 to about 2011, with improvement in bone density to osteopenia. He had also taken vitamin D and calcium supplementation and engaged in regular weight-bearing exercise. The patient had no other known risk factors for decreased bone mineral density preceding the onset of his osteoporosis, and a previous workup for secondary causes of his osteoporosis etiology proved negative. We propose that beta thalassemia minor is potentially a risk factor for osteopenia and osteoporosis, and that bisphosphonates can be considered for management when therapeutic intervention is indicated. Even in the absence of other known risk factors, clinicians should consider periodically screening beta thalassemia minor patients with DXA for evaluation of bone health.

Pheochromocytomas (PCCs) and paragangliomas (PGLs; together PPGLs) are uncommon neuroendocrine tumors arising from adrenal medullary chromaffin cells and sympathetic/parasympathetic paraganglia. Though PPGLs predominate in adult populations, pediatric cases of PPGLs represent more aggressive disease outcomes with 12% being diagnosed as metastatic. Metastatic disease (spread to bone, lung, lymph nodes, or liver) occurs in a subset of PPGLs, ranging from 15% to 17% depending on the underlying pathogenic variants. Historically, pulmonary metastases present clinically as multiple small lesions; however, cases of PPGLs with innumerable small metastases (a miliary pattern) overwhelming lung parenchyma define a novel yet exceptionally challenging disease presentation. This pattern of pulmonary lesions upon treatment and/or cellular lysis may lead to both respiratory decompensation as well as prolific catecholamine release, incurring significant morbidity and mortality if not appropriately managed. Of the 2,649 PPGL patients enrolled in our protocol from January 1, 2000, to April 30, 2023, 500 had metastatic disease, 122 were children/adolescents, and 3 of the 122 children/adolescents had extensive pulmonary metastatic disease. All three adolescent patients with extensive pulmonary metastases had cluster 1 PPGLs and suffered hypoxemia (due to pulmonary metastases) leading to overactive hypoxia signaling and catecholamine-induced signs and symptoms [among them hypertension and/or tachyarrhythmia(s)]. Interventions including surgery, chemotherapy, and radiotherapy were pursued. Two patients achieved disease stability, while one patient succumbed to disease. Ultimately these divergent outcomes emphasize the importance of recognizing poor prognostic factors and aggressive disease early, to select appropriate treatments. Optimal management of these patients must consider complications of catecholamine excess and the profound influence of hypoxia. Herein, we describe three adolescent cases of extensive pulmonary metastatic PPGL and the unique clinical challenges faced in treating these tumors alongside relevant literature to provide guidance on appropriate interventions (ClinicalTrials.gov identifier: NCT00004847).

Obesity is a multifactorial disease linked to many comorbidities and has an impact on brain health. It is also known that obesity disrupts the endocannabinoid (eCB) system in the central nervous system and in the periphery, which complicates the underlying mechanisms behind obesity. However, weight loss through lifestyle interventions or bariatric surgery may alleviate obesity-related comorbidities, as well as restore eCB tone. Several studies have reported a decrease in circulating eCBs following weight loss, likely due to the positive association of these mediators with fat mass. However, further research is needed to clarify whether this reduction is a consequence of weight loss or plays a role in facilitating it. This review explores changes in circulating eCBs following weight loss and their potential roles in cerebral homeostasis and the reward system. It examines how lifestyle modifications and bariatric surgery may influence central eCB signalling and contribute to long-term weight loss success. Understanding the mechanisms behind improved brain function after weight loss could provide insights into optimizing obesity treatments.

Diabetes mellitus is a major risk factor for both cardiovascular and chronic kidney disease (CKD) while CKD is also associated with cardiovascular morbidity. In fact, cardiovascular disease is the leading cause of death in patients with diabetes mainly from heart failure or myocardial infarction. The newer therapeutic agents in diabetes have positive impact on both cardiovascular and renal outcomes. Thus, the American Diabetes Association (ADA)’s annual update on the Standards of Medical Care in Diabetes is an important resource for all caregivers involved in diabetes management as it incorporates the latest scientific research, clinical evidence, and emerging technologies in diabetes management. The 2025 guidelines present significant updates that reflect a deeper understanding of diabetes management, emphasizing expanded usage of technologies such as continuous glucose monitoring, personalized pharmacological approaches, and lifestyle interventions. This commentary provides an analysis of the key updates in the 2025 ADA guidelines exploring implications for clinical practice, laboratory assessments, and public health policy. Where relevant, comparisons to the 2024 version will be made.

Pediatric adrenocortical tumors (pACTs) are rare endocrine neoplasms with variable prognosis, commonly associated with germline pathogenic variants (PVs) in the tumor suppressor gene TP53. Here, we report the case of a 3.1-year-old female presenting with virilization and Cushing syndrome due to a left-sided adrenal mass. The tumor was completely resected and confirmed as stage II adrenocortical carcinoma (ACC) based on the Wieneke index. Comprehensive molecular profiling revealed heterozygous germline PVs in BRCA2 [c.9382C>T p.(Arg3128*)] and CHEK2 [c.1232G>A p.(Trp411*)]. These findings suggest a potential role of impaired DNA damage repair in ACC pathogenesis, as both PVs are associated with hereditary breast and ovarian cancer (HBOC) syndromes and genomic instability. This case expands the genetic spectrum of pACT and underscores the importance of advanced molecular analyses in identifying rare germline alterations that may inform personalized treatment strategies and cancer prevention programs. Although no additional treatment was required in this case, BRCA2 status highlights the potential for tailored therapeutic approaches, including poly(ADP-ribose) polymerase (PARP) inhibitors, in selected patients. Further research is warranted to explore the specific contributions of BRCA2 and CHEK2 PVs to ACC tumorigenesis and their implic ations for targeted therapies.

Hormone replacement therapy (HRT) is essential for alleviating menopausal symptoms and mitigating complications linked to type 2 diabetes mellitus (T2DM) in postmenopausal women. Studies indicate that HRT may contribute to better glycemic control, improved lipid metabolism, and enhanced kidney function, which could help lower the risk of diabetes-related complications. Early initiation of HRT near menopause has shown cognitive and metabolic benefits, while transdermal estrogen is preferred for women with cardiovascular risk due to its safer profile. However, HRT is associated with risks, including thromboembolic events and increased risks of breast and endometrial cancers, necessitating individualized evaluations. Despite its potential, significant gaps remain regarding HRT’s long-term safety and efficacy, its interaction with modern diabetes therapies, and its impact on diverse populations. The optimization of estrogen replacement therapy (ERT) strategies requires further exploration, particularly regarding patient screening, individualized treatment regimens, and personalization of care based on risk factors such as metabolic status, cardiovascular health, and diabetes severity. Current evidence supports the cautious use of HRT in strictly screened postmenopausal women with T2DM, adhering to key principles including early intervention (within 10 years of menopause), low-dose and short-duration therapy (usually < 5 years), and integration of lifestyle interventions (e.g., diet, exercise). Future research should focus on defining clear screening criteria, optimizing treatment regimens, and personalizing ERT to maximize benefits while mitigating risks. This review examines the benefits, risks, and optimization strategies of HRT in postmenopausal women with T2DM. It focuses on its metabolic, cardiovascular, cognitive, and renal effects and emphasizes personalized treatment approaches.

Iatrogenic hypoparathyroidism is a serious complication that can arise from neck surgery, predominantly during thyroidectomy, parathyroidectomy, and laryngectomy; it can be transient or permanent, requiring lifelong treatment. Early detection and treatment are crucial to prevent severe hypocalcemia, which is potentially fatal. This case report describes a 59-year-old male with a history of well-differentiated squamous cell carcinoma of the vocal cords who developed severe postoperative hypoparathyroidism following total laryngectomy with right hemithyroidectomy. Despite initial treatment with cholecalciferol by nasogastric tube, the patient experienced recurrent severe hypocalcemia, requiring intravenous administration of calcitriol due to his inability to swallow. This case highlights the risk factors for triggering postoperative hypoparathyroidism, such as previous surgery or radiotherapy in the cervical region, underlines the importance of careful monitoring of postoperative hypoparathyroidism and proposes the use of intravenous calcitriol as an effective strategy in acute treatment when oral administration is not feasible.

The glucocorticoid receptor (GR) signaling pathway is essential for supporting the integrity of the intestinal barrier, regulating the gut microbiome, and preserving systemic homeostasis in critically ill patients. GR signaling limits bacterial translocation and systemic inflammation by suppressing pro-inflammatory cytokines, reinforcing tight junction proteins, and promoting epithelial renewal. Additionally, physiological levels of glucocorticoids (GCs) stimulate glutamine and proline metabolism, supporting intestinal maturation, with potential clinical relevance. GR signaling modulates inter-organ communication via the gut-lung and gut-brain axes, improving outcomes. Probiotics enhance GC therapy by restoring microbial balance, increasing short-chain fatty acid (SCFA) production, and modulating immune responses. Vitamins A, C, D, and E contribute to gut resilience by stabilizing tight junctions, mitigating oxidative stress, and strengthening mucosal immunity. Specifically, vitamin D balances T-cell subsets and promotes antimicrobial peptides; vitamin C supports collagen synthesis, antioxidant defenses, and immune function; vitamin A promotes immune tolerance and epithelial regeneration; and vitamin E mitigates oxidative damage and excessive cytokine release. GCs, probiotics, and vitamins counteract key drivers of critical illness, including hyperinflammation and dysbiosis, while maintaining strong safety profiles. This integrative approach leverages these interventions’ distinct yet complementary roles to provide a multi-layered defense against gut dysfunction. GCs reduce excessive inflammation and restore immune balance; probiotics enhance microbial diversity and strengthen gut-associated immunity; and vitamins support epithelial integrity and antioxidant defenses. Targeting multiple pathways simultaneously protects the gut barrier and modulates systemic immunity, potentially reducing complications such as sepsis, multiple organ dysfunction syndrome (MODS), and prolonged intensive care unit (ICU) stays. Incorporating these elements into critical care practice offers a novel strategy to mitigate gut dysfunction, reduce systemic inflammation, and enhance immune resilience. This approach may lower infection rates, decrease the incidence of sepsis and MODS, and accelerate recovery by targeting GR signaling, restoring microbial homeostasis, and reinforcing epithelial integrity.
