Insidious gastrointestinal bleeding from a secondary aortic fistula poses a significant diagnostic challenge. Failure to recognize it early on can lead to devastating outcomes. We describe a case of insidious gastrointestinal bleeding from a secondary aortic fistula in an elderly woman who presented with recurrent admissions for melanotic stools and eventually developed septic shock. Esophagogastroduodenoscopy did not reveal any obvious source of bleeding. The patient eventually had push endoscopy that revealed infected graft and a secondary aortoduodenal fistula. One should proceed with push enteroscopy in occult bleeding if the patient has a history of abdominal aortic aneurysm repair.

Background: The escalating demographic shift towards an aging population and the widespread occurrence of immunological diseases have contributed to an elevation in the frequency of community-acquired infections. Notably, among these infections, community-acquired bloodstream infections (CABSI) stand out due to their significant lethality. Detailed medical history inquiries, assessment of underlying immune status, detection of the source of infection, and initial precise identification and treatment of the infectious agents can improve the prognosis of CABSI.

Invasive lobular carcinoma (ILC) is the second most prevalent form of invasive breast cancer. Characterized by its insidious growth and distinctive histopathological features, ILC often presents with a less predictable metastatic pattern, including potential invasion of the gastrointestinal tract. This report presents the case of a patient with ILC who developed ileocecal valve metastasis leading to cecal volvulus, a rare but critical complication.

Sjögren's disease (SjD), or primary Sjögren's syndrome (pSS), is a heterogeneous chronic autoimmune disorder with multiple clinical manifestations that can develop into non-Hodgkin's lymphoma in mucosa-associated lymphoid tissue. SjD is one of the autoimmune diseases with the maximum delayed diagnosis due to its insidious onset, heterogeneous clinical features and varied course. It is increasingly recognized that extraglandular manifestations represent a clinical challenge for patients with SjD.

The pervasive presence of microplastics (MPs) in infant formula and care products has emerged as a significant and underappreciated risk to public health. Notably, infants are at an elevated risk due to their underdeveloped intestinal defenses and liver detoxification capabilities, factors that could heighten their vulnerability to MPs. This study presents a comprehensive evaluation of the health implications linked to polystyrene microplastics (PSMPs) exposure during early life, examining both environmentally plausible and elevated levels.

Article Synopsis
- * While some obesity-related problems in children, like musculoskeletal and skin disorders or sleep apnea, are well-known, others like kidney issues, non-alcoholic fatty liver disease, and cardiometabolic risks are less recognized due to their gradual onset over time.
- * Additionally, obesity presents significant psychosocial challenges and complicates medical procedures, particularly airway management, highlighting the importance of addressing these issues early in childhood for better long-term health.
