Spontaneous regression of non-small cell lung cancer is relatively rare. Here, we present a very rare case of spontaneous regression of lung cancer which occurred in a patient with basaloid squamous cell lung cancer. To the best of our knowledge, this is the first report of such a case. A 76-year old man was referred to our hospital with nodules in the right upper lobe determined by chest computed tomography. The nodules spontaneously regressed during follow-up. Two years later, the tumor had regrown and the patient subsequently underwent surgery. The pathological findings showed basaloid squamous cell carcinoma. Stimulation of the immune system was considered to be the cause of the spontaneous regression and CD-8 positive and CD-4 positive lymphocytes might play an important role.

Spontaneous regression in breast cancer is rare but can dramatically improve patient prognosis. Although the underlying mechanism is unknown, it may be due to a biological response to external invasion. An 81-year-old woman presented to our emergency department with a 600x100mm large breast mass.

Objective: To study the correlation between anti-Müllerian hormone levels and pregnancy outcomes after in vitro fertilization/intracytoplasmic sperm injection in women with polycystic ovary syndrome, which remains controversial.
Methods: This retrospective cohort study recruited 4,719 women with infertility and polycystic ovary syndrome aged 20-40 years who underwent treatment at the Reproductive Center of Peking University Third Hospital between February 2017 and June 2023. We divided the participants into three groups according to the 25th and 75th percentile cutoffs of serum anti-Müllerian hormone: low (≤ 4.
Predictive role of SLC1A5 in neuroblastoma prognosis and immunotherapy.

Background: Neuroblastoma, a prevalent extracranial solid tumor in pediatric patients, demonstrates significant clinical heterogeneity, ranging from spontaneous regression to aggressive metastatic disease. Despite advances in treatment, high-risk neuroblastoma remains associated with poor survival. SLC1A5, a key glutamine transporter, plays a dual role in promoting tumor growth and immune modulation.

Division of Rheumatology, Allergy and Immunology, Department of Medicine, University of Cincinnati College of Medicine, Cincinnati, OH, USA.
Background: In the context of injectable biologic products approved or in development for chronic spontaneous urticaria (CSU), it is important to capture which treatment attributes matter most to patient and what trade-offs patients are willing to make.
Objectives: The CHOICE-CSU study aimed to quantify patient preferences toward injectable treatment attributes among patients with CSU, inadequately controlled by H1-antihistamines.
Methods: This was a two-phase cross-sectional patient preference study in adult patients with a diagnosis of CSU, inadequately controlled by H1-antihistamines.
Prevalence and Prognostic Impact of ST Segment Elevation in Lead aVR Among Patients with Cardiac Arrest.

Section of Cardiovascular Medicine, Yale School of Medicine, New Haven, CT.
Background: In acute coronary syndrome, ST-segment elevation in lead aVR (STE-aVR) indicates global myocardial ischemia, often related to multivessel or severe left main disease, and correlates with increased mortality. The prevalence and prognostic significance of STE-aVR in cardiac arrest (CA) patients is unknown.
Methods: We identified patients (≥18 years) with CA between 2011 to 2022 who achieved return of spontaneous circulation (ROSC).
