he long-term outcomes in preterm infants.

While ventricular size indices from serial cUS are superior to clinical signs of increased intracranial pressure to assess PHVD, questions remained on their inter-observer reproducibility and reliability to predict severity of PHVD. AHW and VI are highly reproducible when performed by experienced clinicians. CT-707 purchase AHW from the second week of birth is the strongest predictor of PHVD onset and severity. AHW, combined with VI, may aid in early PHVD diagnosis and decision-making on need for surgical intervention. Consistent use of these indices has the potential to improve PHVD management and therewith the long-term outcomes in preterm infants.Aberrant activation of NF-κB is the most striking oncogenic mechanism in B-cell lymphoma; however, its role in anaplastic large cell lymphomas (ALCL) has not been fully established and its activation mechanism(s) remain unclear. Using ALCL cell line models, we revealed the supporting roles for NFKB2 and the NIK pathway in some ALCL lines. To investigate the detailed activation mechanisms for this oncogenic pathway, we performed specifically designed alternative NF-κB reporter CRISPR screens followed by the RNA-seq analysis, which led us to identify STAT3 as the major mediator for NIK-dependent NF-κB activation in ALCL. Consistently, p-STAT3 level was correlated with NFKB2 nuclear accumulation in primary clinical samples. Mechanistically, we found that in NIK-positive ALK- ALCL cells, common JAK/STAT3 mutations promote transcriptional activity of STAT3 which directly regulates NFKB2 and CD30 expression. Endogenous expression of CD30 induces constitutive NF-κB activation through binding and degrading of TRAF3. In ALK+ ALCL, the CD30 pathway is blocked by the NPM-ALK oncoprotein, but STAT3 activity and resultant NFKB2 expression can still be induced by NPM-ALK, leading to minimal alternative NF-κB activation. Our data suggest combined NIK and JAK inhibitor therapy could benefit patients with NIK-positive ALK- ALCL carrying JAK/STAT3 somatic mutations.

The purpose of this study is to examine the seasonal patterns of incidence, demographic factors and microbiological profiles of infectious keratitis (IK) in Nottingham, UK.

A retrospective study of all patients who were diagnosed with IK and underwent corneal scraping during 2008-2019 at a UK tertiary referral centre. Seasonal patterns of incidence (in per 100,000 population-year), demographic factors, culture positivity rate and microbiological profiles of IK were analysed.

A total of 1272 IK cases were included. The overall incidence of IK was highest during summer (37.7, 95% confidence interval (CI) 31.3-44.1), followed by autumn (36.7, 95% CI 31.0-42.4), winter (36.4, 95% CI 32.1-40.8) and spring (30.6, 95% CI 26.8-34.3), though not statistically significant (p = 0.14). The incidence of IK during summer increased significantly over the 12 years of study (r = 0.58, p = 0.049), but the incidence of IK in other seasons remained relatively stable throughout the study period. Significant seasonal variatin of younger age, P. aeruginosa and gram-positive bacilli infection with summer was likely attributed to contact lens wear, increased outdoor/water activity and warmer temperature conducive for microbial growth.

This study aimed to evaluate the risk factors of postoperative severe vision impairment (PSVI) for a primary orbital tumour in the muscle cone.

A retrospective analysis of the patients who underwent orbitotomy for primary intraconal tumours at the Tianjin Medical University Eye Hospital from January 2010 to December 2015.

A total of 165 cases of orbitotomy for primary orbital tumours in the muscle cone were included in the study. Postoperatively, 12 cases with vision acuity ≤20/400 or ≥4 rows of vision decline and without any corrected effect were analysed as PSVI, including no light perception (NLP) for 3 cases. The multivariate logistic regression indicated that the tumour in orbital apex (P = 0.048, OR = 4.912, 95% CI 1.011-23.866), severe optic nerve displacement (P = 0.030, OR = 6.007, 95% CI 1.184-30.473) and intraoperative tight adhesion (P = 0.003, OR = 12.031, 95% CI 2.282-63.441) were the independent risk factors for PSVI.

The incidence of PSVI for the intraconal tumour was 7.3%, and the incidence of NLP was 1.8%. The tumour in orbital apex, severe optic nerve displacement and intraoperative tight adhesion were independent risk factors for PSVI.

To investigate outcomes for small versus large pupils in cataract surgery using different pupil expansion techniques.

Retrospective case-series reviewing 20,175 patients’ cataract surgery electronic medical records at Moorfields Eye Clinic in Bedford Hospital NHS Trust from January 2010 to April 2020. Outcomes such as visual acuity (VA), intraocular pressure, intraoperative, post-operative complications were recorded and small pupil expansion device outcome.

One thousand, four hundred twenty-six patients were identified as having small pupil (SP). Of these, 1110 patients (77.8%) had interventions to expand the pupil including 447 (31.3%) with intracameral phenylephrine (IC PE) alone, 194 (13.6%) with iris hooks and 469 (32.9%) with a Malyugin ring. The large pupil (LP) group had a statistically significant greater gain in VA than the SP group (p < 0.05). SPs had a significantly higher rate of intraocular complications including posterior capsular rupture (PCR) with vitreous loss (OR 2.75, p < 0.00ris tears with Malyugin ring.It is not clear whether the influence of arterial stiffness depends on the subject’s cardiovascular risk status. This study was performed to assess the prognostic value of arterial stiffness according to different cardiovascular risk profiles. A total of 11,767 subjects (61 years and 58% males) who underwent brachial-ankle pulse wave velocity (baPWV) measurement were retrospectively analyzed. Subjects were stratified into three groups (1) those with traditional risk factor ≤1 and without atherosclerotic cardiovascular disease (ASCVD), (2) those with traditional risk factors ≥2 and without ASCVD, or (3) those with documented ASCVD. Composite events of cardiac death, non-fatal myocardial infarction, coronary revascularization and stroke were assessed during the clinical follow-up period. Compared to patients with risk factor ≤1, those with risk factor ≥2 and those with ASCVD were older, and more frequently had unfavorable laboratory findings, and higher baPWV values. During the median follow-up of 1329 days (interquartile range, 570-1,965 days), there were 350 composite events (3.
