Current standard initial therapy for advanced, ROS proto-oncogene 1, receptor tyrosine kinase fusion (
)-positive (ROS1
) non-small cell lung cancer (NSCLC) is crizotinib or entrectinib. Lorlatinib, a next-generation anaplastic lymphoma kinase/ROS1 inhibitor, recently demonstrated efficacy in ROS1
NSCLC, including in crizotinib-pretreated patients. However, mechanisms of lorlatinib resistance in ROS1
disease remain poorly understood. Here, we assessed mechanisms of resistance to crizotinib and lorlatinib.

Biopsies from patients with ROS1
NSCLC progressing on crizotinib or lorlatinib were profiled by genetic sequencing.

From 55 patients, 47 post-crizotinib and 32 post-lorlatinib biopsies were assessed. Among 42 post-crizotinib and 28 post-lorlatinib biopsies analyzed at distinct timepoints,
mutations were identified in 38% and 46%, respectively.
G2032R was the most commonly occurring mutation in approximately one third of cases. Additional
mutations included D2033N (2.4%) and S1986F (2.esistance to crizotinib and lorlatinib in more than one third of cases, underscoring the importance of developing next-generation ROS1 inhibitors with potency against these mutations, including G2032R and L2086F. Continued efforts are needed to elucidate ROS1-independent resistance mechanisms.
exon 20 insertions (ex20ins) are an uncommon genotype in non-small cell lung cancer (NSCLC) for which targeted therapies are under development. We sought to describe treatment outcomes and genomic and immunophenotypic characteristics of these tumors.

We identified sequential patients with NSCLC with
ex20ins and compared their clinical outcomes and pathologic features with other patients with NSCLC.

Among 6,290 patients with NSCLC, 106 (2%) had
ex20ins. Patients with
ex20ins were more likely to be Black (14% vs. 6%;
< 0.001) or Asian (22% vs. 10%;
< 0.001) compared with all other patients with NSCLC. Median tumor mutational burden (TMB; 3.5 vs. 5.9;
< 0.001) and proportion of tumors with PD-L1 expression ≥1% (22% vs. 60%;
< 0.001) were lower in
ex20ins compared with other NSCLCs (TMB,
= 5,851 and PD-L1 expression,
= 282) and
del 19/L858R (median TMB, 3.5;
= 0.001 and 39% PD-L1 ≥ 1%;
= 0.02). Compared with a 21 cohort of patients with metastatic NSCLC without targetable alterations (
= 192),
ex20ins patients had longer overall survival (median 20 vs. 12 months; HR, 0.56;
= 0.007) and longer time to treatment discontinuation (TTD) for platinum chemotherapy (median, 7 vs. 4 months; HR, 0.6;
= 0.02) and no improvement in TTD for immune checkpoint inhibitors (ICI; HR, 1.75;
= 0.05).

With better outcomes on platinum chemotherapy, patients with
ex20ins NSCLC have improved prognosis, lower PD-L1 expression and TMB, and derive less benefit from ICIs compared with patients with NSCLC without targetable oncogenes. Improving molecularly targeted therapies could provide greater benefit for patients with
ex20ins.
With better outcomes on platinum chemotherapy, patients with EGFR ex20ins NSCLC have improved prognosis, lower PD-L1 expression and TMB, and derive less benefit from ICIs compared with patients with NSCLC without targetable oncogenes. Improving molecularly targeted therapies could provide greater benefit for patients with EGFR ex20ins.
Vitamin D receptor activators and calcimimetics (calcium-sensing receptor agonists) are two major options for medical treatment of secondary hyperparathyroidism. A higher serum calcification propensity (a shorter T
value) is a novel surrogate marker of calcification stress and mortality in patients with CKD. We tested a hypothesis that a calcimimetic agent etelcalcetide is more effective in increasing T
value than a vitamin D receptor activator maxacalcitol.

A randomized, multicenter, open-label, blinded end point trial with active control was conducted in patients with secondary hyperparathyroidism undergoing hemodialysis in Japan. Patients were randomly assigned to receive intravenous etelcalcetide 5 mg thrice weekly (etelcalcetide group) or intravenous maxacalcitol 5 or 10
g thrice weekly (maxacalcitol group). The primary, secondary, and tertiary outcomes were changes in T
value, handgrip strength, and score of the Dementia Assessment Sheet for Community-Based Integrated Care System from baselipatients on hemodialysis with secondary hyperparathyroidism. There was no difference in handgrip strength or cognition between the two drugs.

To synthesise evidence on low back pain (LBP) in adult rowers and to create a consensus statement to inform clinical practice.

There were four synthesis steps that informed the consensus statement. In step one, seven expert clinicians and researchers established the scope of the consensus statement and conducted a survey of experienced and expert clinicians to explore current practice. APR-246 In step two, working groups examined current evidence relating to key scope questions and summarised key issues. In step three, we synthesised evidence for each group and used a modified Delphi process to aid in the creation of the overall consensus statements. Finally, in step four, we combined information from step three with the findings of the clinician survey (and with athlete and coach input) to produce recommendations for clinical practice.

The scope of the consensus statement included epidemiology; biomechanics; management; the athlete's voice and clinical expertise. Prevention and management of LBP in rowers shounagement of LBP in rowers be intensified.
Studies of seizure management in the pediatric inpatient setting are needed. Seizures recorded by video EEG provide an opportunity to quantitatively evaluate acute management. We observed variation in delivery of standardized seizure safety measures (seizure first aid) during epilepsy monitoring unit admissions at our hospital. Our goals were to increase consistency and speed of seizure first aid and neurologic assessment in acutely seizing patients.

Using a root cause analysis, we identified major factors contributing to variation in seizure management and key drivers for improvement. Targeted interventions, centered around a protocol for acute seizure management, were implemented through quality improvement methodology. The primary outcome was correct performance of standardized seizure first aid and neurologic assessment. Secondary outcomes were time intervals to each assessment. Run charts were used to analyze primary outcomes, and statistical control charts were used for secondary outcomes. Nursing confidence in seizure management was determined through pre- and postsurveys and analyzed with the χ
test.
