Stereotactic ablative radiotherapy (SABR) has emerged as an alternative, non-surgical treatment for high-risk patients with stage I non-small cell lung cancer (NSCLC) with increased use over time. The American Association for Thoracic Surgery (AATS) Clinical Practice Standards Committee (CPSC) assembled an expert panel and conducted a systematic review of the literature evaluating the results of SABR, which is also referred to as stereotactic body radiation therapy (SBRT) or stereotactic radiosurgery (SRS), prior to developing treatment recommendations for high-risk patients with stage I NSCLC based on expert consensus. Publications detailing the findings of 16 prospective studies of SABR and 14 retrospective studies of SABR for the management of early-stage lung cancer in 54 697 patients were identified by systematic review of the literature with further review by members of our expert panel.

Sublobar resection offers a parenchymal-sparing surgical alternative to lobectomy and includes wedge resection and segmentectomy. Sublobar resection has been historically utilized in high-risk patients with compromised lung function; however, the technique is becoming more prevalent for normal-risk patients with peripheral lung tumors < 2 cm. In this article, we summarize the technique of sublobar resection, the importance of surgical margins and lymph node sampling, patient selection, perioperative complications, outcomes, and the impact of sublobar resection on the quality of life.

Background: Among presenting conditions in pediatric acute care settings, conduct disorder (CD) is a potentially stigmatizing yet common diagnosis in the setting of behavioral dysregulation requiring psychiatric admission. Concerns exist about over-diagnosis of CD in non-Hispanic Black children relative to White peers and the potential for the CD diagnosis to obfuscate manifestations of co-occurring psychiatric conditions.

Methods: We evaluated the number of manuscripts on CD diagnoses that report race and ethnicity and co-occurring mental health characteristics (i.

Traumatic brain injury (TBI) is common and costly. Although neuroimaging modalities such as resting-state functional MRI (rsfMRI) promise to differentiate injured from healthy brains and prognosticate long-term outcomes, the field suffers from heterogeneous findings. To assess whether this heterogeneity stems from variability in the TBI populations studied or the imaging methods used, and to determine whether a consensus exists in this literature, we performed the first systematic review of studies comparing rsfMRI functional connectivity (FC) in patients with TBI to matched controls for seven canonical brain networks across injury severity, age, chronicity, population type, and various imaging methods.

The complete blood count (CBC) is an important screening tool for healthy adults and a common test at periodic exams. However, results are usually interpreted relative to one-size-fits-all reference intervals, undermining the precision medicine goal to tailor care for patients on the basis of their unique characteristics. Here we study thousands of diverse patients at an academic medical centre and show that routine CBC indices fluctuate around stable values or setpoints, and setpoints are patient-specific, with the typical healthy adult's nine CBC setpoints distinguishable as a group from those of 98% of other healthy adults, and setpoint differences persist for at least 20 years.

Image-guided thermal ablation (IGTA) applied to pulmonary pathology is an alternative to surgery in high-risk patients with stage I non-small cell lung cancer (NSCLC). Its application to lung neoplasm was first introduced in 2001 and has been implemented to treat metastatic disease to the lung or in select medically inoperable patients with peripheral stage I NSCLC. IGTA may also be an alternative to treat stage I NSCLC in non-operable patients with interstitial lung disease in whom a radiation modality is deemed too high risk.

Partitioned polygenic risk scores identify distinct types of metabolic dysfunction-associated steatotic liver disease.

Nat Med

Department of Molecular and Clinical Medicine, Institute of Medicine, Sahlgrenska Academy, Wallenberg Laboratory, University of Gothenburg, Gothenburg, Sweden.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is characterized by an excess of lipids, mainly triglycerides, in the liver and components of the metabolic syndrome, which can lead to cirrhosis and liver cancer. While there is solid epidemiological evidence that MASLD clusters with cardiometabolic disease, several leading genetic risk factors for MASLD do not increase the risk of cardiovascular disease, suggesting no causal relationship between MASLD and cardiometabolic derangement. In this work, we leveraged measurements of visceral adiposity identifying 27 previously unknown genetic loci associated with MASLD (n = 36,394), six replicated in four independent cohorts (n = 3,903).
