Developmental transitions are typically tightly controlled at the transcriptional level. Two of these transitions involve the induction of the embryo maturation program midway through seed development and its repression during the vegetative phase of plant growth. Very little is known about the factors responsible for this regulation during early embryogenesis, and only a couple of transcription factors have been characterized as repressors during the postgerminative phase. Arabidopsis 6b-INTERACTING PROTEIN-LIKE1 (ASIL1), a trihelix transcription factor, has been proposed to repress maturation both embryonically and postembryonically. Preliminary data also suggested that its closest paralog, ASIL2, might play a role as well. We used a transcriptomic approach, coupled with phenotypical observations, to test the hypothesis that ASIL1 and ASIL2 redundantly turn off maturation during both phases of growth. Our results indicate that, contrary to what was previously published, neither of the ASIL genes plays a role in the regulation of maturation, at any point during plant development. Analyses of gene ontology (GO)-enriched terms and published transcriptomic datasets suggest that these genes might be involved in responses during the vegetative phase to certain biotic and abiotic stresses.

This case report describes a unique case of a young patient with retinopathy of prematurity (ROP), a unilateral Coats-like response, and X-linked retinoschisis (XLRS).

A 9-year-old boy with a history of regressed ROP presented with a unilateral Coats-like response, subretinal exudation, and XLRS. Examination and imaging findings demonstrated a highly unique combination of bilateral retinoschisis and a dramatic unilateral Coats-like response with a large schisis cavity.

Treatment with laser photocoagulation and anti-VEGF therapy led to resolution of the subretinal exudative changes.

This is the first published description to our knowledge of a patient with a Coats-like response, XLRS, and a history of regressed ROP with resolution after treatment.

Molecular tumor boards (MTBs) represent a strategy to increase precision medicine use. click here UK HealthCare at the University of Kentucky (UK) implemented a statewide MTB in January 2017. We wanted to test the impact of UK MTB review on overall survival in Appalachian and other regions in Kentucky.

We performed a case-control study of Kentucky patients newly diagnosed with non-small-cell lung cancer between 2017 and 2019. Cases were reviewed by the UK MTB and were compared with controls without UK MTB review. Controls were identified from the Kentucky Cancer Registry and propensity-matched to cases. The primary end point was the association between MTB review and overall patient survival.

Overall, 956 patients were included, with 343 (39%) residing in an Appalachian region. Seventy-seven (8.1%) were reviewed by the MTB and classified as cases. Cox regression analysis showed that poorer survival outcome was associated with lack of MTB review (hazard ratio [HR] = 8.61; 95% CI, 3.83 to 19.31;

< .0001) and living in an Appalachian region (hazard ratio = 1.43; 95% CI, 1.17 to 1.75;

= .004). Among individuals with MTB review, survival outcomes were similar regardless of whether they lived in Appalachia or other parts of Kentucky.

MTB review is an independent positive predictor of overall survival regardless of residence location. MTBs may help overcome some health disparities for disadvantaged populations.

Information on the economic burden of focal segmental glomerulosclerosis (FSGS) is sparse. link2 This study characterized health care resource utilization (HCRU) and costs in patients with FSGS, and evaluated the impact of nephrotic range proteinuria on these outcomes.

This retrospective, observational cohort study used administrative claims data from the Optum Clinformatics Data Mart Database from October 2015 to December 2019. Patients with FSGS (

= 844; first claim= index event) between April 2016 and December 2018 were matched on index date, age, sex, and race to non-FSGS controls (

= 1688). FSGS nephrotic range (urine protein/creatinine ratio >3000 mg/g or albumin/creatinine ratio >2000 mg/g) and non-nephrotic subpopulations were identified. Baseline comorbidities, 12-month post-index all-cause HCRU and costs (per patient per year [PPPY]), and immunosuppressant prescriptions were compared between matched cohorts and between FSGS subpopulations.

Comorbidity burden was higher in FSGS. Of 308 patienhe economic burden. New treatment modalities are needed to reduce proteinuria, help improve patient outcomes, and reduce HCRU and associated costs.

Managing complex and rare systemic autoimmune diseases such as antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) can be challenging and is often accompanied by undesirable variations in clinical practice. Adequate understanding of clinical practice can help identify essential issues to improve the care for AAV patients. Therefore, we studied the real-life management and outcomes of AAV patients in the Netherlands.

In this cohort study, we investigated clinical practice in university and nonuniversity teaching hospitals with respect to patients with a clinical diagnosis of AAV. We retrospectively collected clinical data encompassing clinical variables, medication details, and outcome parameters.

Data of 230 AAV patients were collected in 9 Dutch hospitals. Of these, 167 patients (73%) were diagnosed with granulomatosis with polyangiitis, 54 (24%) with microscopic polyangiitis and 9 (4%) with eosinophilic granulomatosis with polyangiitis. One hundred sixty-six patients (72%) had generesulted in important indicators for treatment of AAV patients that can be implemented for future, national audits to improve the outcomes of AAV patients.

Recent studies have revealed the pivotal role of complement activation in the pathogenesis of antineutrophil cytoplasmic antibody-associated glomerulonephritis (ANCA-GN). This study investigated the clinicopathologic and prognostic significance of glomerular C3 deposition in the renal histopathology of patients with ANCA-GN.

We retrospectively identified 142 patients with ANCA-GN from 6 hospitals in Japan (2004-2020). C3 deposition was defined as C3 staining≥1+ on a scale of 0 to 2+ using direct immunofluorescence (IF). The primary composite end points included a 30% reduction in estimated glomerular filtration rate (eGFR), end-stage kidney disease (ESKD), and death. We compared clinicopathologic features and long-term outcomes between patients with and without C3 deposition.

C3 deposition was observed in 56 of 142 kidney biopsy samples (39.4%). Patients with C3 deposition had a lower serum C3 level (

= 0.002). During a median follow-up of 2.9 (interquartile range 0.2-5.7) years, 69 events occurred and the cumulative event-free survival rate at 5 years was significantly lower in the C3-positive group than in the C3-negative group (log-rank

= 0.002). In multivariable analysis, C3 deposition was significantly associated with the composite end points after adjusting for age, sex, baseline eGFR, serum C3 level, treatment, and the percentage of normal glomerulus, cellular crescents, global sclerosis, and interstitial damage (adjusted hazard ratio [HR]= 2.02, 95% confidence interval 1.20-3.40,

= 0.008).

This study revealed that ANCA-GN patients with glomerular C3 deposition on IF had worse renal and overall survival rates.

Kidney Disease Improving Global Outcomes (KDIGO) 2012 recommends cyclical cyclophosphamide plus glucocorticoids (GC) (modified Ponticelli regimen) or calcineurin inhibitors (CNIs) such as tacrolimus (TAC) or cyclosporine as the first-line agents for the management of primary membranous nephropathy (PMN) that is resistant to antiproteinuric therapy with renin-angiotensin system blockers. However, the long-term outcome of patients treated with CNIs is not known.

We report the outcomes of 70 patients randomized 11 to receive modified Ponticelli regimen or TAC/GC for renin-angiotensin system-resistant PMN who were prospectively followed for 6 years. Patients were followed monthly for 12 months, then quarterly for 12 months, and then every 6 months through the end of 6 years.

At the end of 6 years, 21 (61.76%) and 9 (28.12%) patients maintained relapse-free remission in modified Ponticelli regimen and TAC/GC groups, respectively (relative risk [RR] 2.19, 95% confidence interval [CI] 1.23 to 4.15), and 30 (88.23%) and 17 (53.12%) patients were in remission (including relapses) in modified Ponticelli regimen and TAC/GC groups (RR 1.66; 95% CI 1.21 to 2.45), respectively. There was no significant difference in the proportion of patients who had a 40% decline in the estimated glomerular filtration rate (eGFR), death, or end-stage kidney disease between the groups. None of the patients treated with modified Ponticelli regimen reported a solid organ or hematological malignancy.

To conclude, in the long-term, modified Ponticelli regimen is superior to TAC/GC as first-line therapy for the management of antiproteinuric-resistant PMN.

Familial hyperkalemic hypertension is a rare inherited form of arterial hypertension. Four genes are responsible for this disease, the variants of these genes cause disruption in the regulation of ion transport in the distal renal tubule. Whether the genotype explains the large phenotypic heterogeneity has not been fully explored.

We retrospectively analyzed clinical and genetic data of 153 cases (84 probands, 69 relatives) with familial hyperkalemic hypertension.

Pathogenic variants (25 novel variants) were identified as follows

(n= 50),

(n= 16),

acidic motif (n= 11),

acidic motif (n= 4) and

intron 1 deletions (n= 3).

cases were mainly observed in the

-related cases (9 of 12) and recessive cases were only observed in

-related cases (14 of 50). More severe forms were observed in recessive

and

cases that were also associated with growth retardation. link3 Patients with

acidic motif variants had a typical biological phenotype and lower frequency of hypertension conversely to

variants affecting the same motif. Patients with heterozygous

and

deletions had milder forms. Familial screening in 178 relatives allowed detection and care for 69 positive cases. Blood pressure and hyperkalemia were improved by hydrochlorothiazide in all groups.

This study confirms the phenotypic variability ranging from the severe and early forms associated with

and recessive

genotypes through intermediate forms associated with

dominant,

and

deletion to mild form associated with

acidic motif genotype and reinforces the interest of genetic screening to better orientate medical care and genetic counseling.

This study confirms the phenotypic variability ranging from the severe and early forms associated with CUL3 and recessive KLHL3 genotypes through intermediate forms associated with KLHL3 dominant, WNK4 and WNK1 deletion to mild form associated with WNK1 acidic motif genotype and reinforces the interest of genetic screening to better orientate medical care and genetic counseling.
