25), which increased to 11.00 (8.75, 12.00) at PICU discharge before decreasing to 7.50 (6.00, 9.25) at hospital discharge. All patients had significantly higher FSS at both PICU and hospital discharge median compared to baseline. Feeding and respiratory were the most affected domains. After adjusting for severity of illness, severity categories of PARDS were not a risk factor for acquired morbidity.

Acquired morbidity in respiratory and feeding domains was common in PARDS survivors. Specific attention should be given to these two domains of functional outcomes in these children.

Fenebrutinib (GDC-0853, FEN) is a non-covalent, oral, and highly selective inhibitor of Bruton's tyrosine kinase (BTK). The efficacy, safety, and pharmacodynamics of FEN were assessed in this randomized, placebo-controlled, multi-center phase II study.

Patients with moderate-to-severely active systemic lupus erythematosus on background standard of care therapy were randomized to placebo, FEN 150 mg QD, or FEN 200 mg BID arms. Corticosteroid taper was recommended from weeks 0 to 12 (W0-W12) and W24-W36. The primary endpoint was SRI-4 at W48.

Patients (N=260) were enrolled from 44 sites in 12 countries, with the majority from Latin America, USA, and Western Europe. The SRI-4 response rates at W48 were 51% (p=0.37, versus placebo) for FEN 150 mg QD, 52% (p=0.34, versus placebo) for FEN 200 mg BID, and 44% for placebo. BICLA response rates at W48 were 53% (p=0.086, versus placebo) for FEN 150 mg QD, 42% (p=0.879, versus placebo) for FEN 200 mg BID, and 41% for placebo. Safety results were similar across all arms, although serious adverse events were more frequent with FEN 200 mg BID. By W48, patients treated with FEN had reduced levels of a BTK-dependent plasmablast RNA signature, anti-dsDNA autoantibodies, total IgG, and IgM, as well as increased complement C4, all relative to placebo.

While FEN had an acceptable safety profile, the primary endpoint, SRI-4, was not met despite evidence of strong pathway inhibition.

After an initial easy phase to the breath hold, this voluntary control is applied against the increasing involuntary effort to inspire. We quantified an electromyographic (EMG) signal associated with respiratory movements derived from broad bandpass ECG recordings taken from experienced breath holding divers during prolonged dry breath holds. We sought to define their relationship to involuntary respiratory movements and compare these signals with what is known to occur in obstructive sleep apnea (OSA) and epileptic seizures. ECG and inductance plethysmography records from 14 competitive apneists (1 female) were analyzed. ECG records were analyzed for intervals and the EMG signal was extracted from a re-filtered version of the original broad bandpass signal and ultimately enveloped with a Hilbert transform. EMG burst magnitude, quantified as an area measure, increased over the course of the struggle phase, correlated with inductance plethysmography measures, and corresponded to significant variance in heart rate variability. We conclude that an EMG signal extracted from the ECG can complement plethysmography during breath holds and may help quantify involuntary effort, as reported previously for obstructive sleep apnea. Further, given the resemblance between cardiac and respiratory features of the breath hold struggle phase to obstructive apnea that can occur during sleep or in association with epileptic seizure activity, the struggle phase may be a useful simulation of obstructive apnea for controlled experimentation that can help clarify aspects of acute and chronic apnea-associated physiology.

ARID1A is a component of the SWI/SNF complex, which controls the accessibility of proteins to DNA. ARID1A mutations are frequently observed in colorectal cancers (CRCs) and have been reported to be associated with high mutational burden and tumor PD-L1 expression in vitro.

To clarify the role of ARID1A mutation in CRC.

We used next generation sequencing (NGS) and immunohistochemistry on clinically obtained samples. A total of 201 CRC tissues from Niigata University and Niigata Center Hospital were processed by NGS using the CANCERPLEX panel. Immunohistochemistry for ARID1A, PD-L1, MLH1, and MSH2 was performed on 66 propensity-matched (33 microsatellite instability-high [MSI-H] and 33 microsatellite-stable [MSS]) cases among 499 cases from Kyushu University. TCGA data were downloaded from cBioPortal. NGS showed significantly more mutations in ARID1A mutated CRCs (p=0.01), and the trend was stronger for right-sided CRCs than left-sided. TCGA data confirmed these findings (p < 0.01). Protein Tyrosine Kinase inhibitor BRAF V600E and ATM mutations were also found at higher frequencies. Immunohistochemistry showed that 30% of MSI-H CRCs had ARID1A loss, while this was true in only 6% of MSS CRCs. In both MSI-H and MSS, PD-L1 expression by stromal cells was enhanced in the ARID1A-mutant groups (90% vs 39% in MSI-H, 100% vs 26% in MSS).

We found a higher mutational burden in ARID1A-mutant CRCs, and IHC study showed that ARID1A loss was correlated with high PD-L1 expression in stromal cells regardless of MSI status. These data support the idea that mutant ARID1A is a potential biomarker for CRCs.

(1) A mean blood level of 1068 ng/mL and a most recent level of 1192 ng/mL and above had a protective effect. The dose response implied a therapeutic threshold of HCQ. However, a previous study indicated a range of HCQ blood level from 1177 to 3513 ng/mL predicted later development of HCQ retinopathy. (2) Obviously, there's a great overlap between the protective level from thrombosis and toxic level of retinopathy. The optimal therapeutic range is so narrow (1068 to 1177 ng/mL) that dose titration to target this level would be difficult in clinical practice. It seems that the dilemma of avoiding retinopathy while maintaining the benefit of HCQ still exists.
