Baseline characteristics of children in the early glasses study. Graefes Arch Clin Exp Ophthalmol 2024:10.1007/s00417-024-06621-8. [PMID: 39235501 DOI: 10.1007/s00417-024-06621-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2024] [Revised: 07/13/2024] [Accepted: 08/15/2024] [Indexed: 09/06/2024] Open
Abstract
PURPOSE The relationship between refractive error at age 1 and the risk of developing amblyopia or accommodative esotropia, and the protection offered by early glasses, is unknown. These are determined in the Early Glasses Study, a prospective, population-based, longitudinal, randomized controlled study. We report baseline findings. METHODS Healthy children aged 12-18 months were recruited at Children's Healthcare Centres (CHCs) and received an entry orthoptic examination followed by cycloplegic retinoscopy. Children with amblyopia, strabismus, ophthalmic disease or very high refractive error were excluded. Those exceeding the AAPOS 2003 Criteria (> + 3.5D spherical equivalent (SE), > 1.5D astigmatism, > 1.5D anisometropia) were randomized into wearing glasses or not, and are followed-up by research orthoptists. Other children are followed-up by regular vision screening at CHCs and visual acuity is measured in all children at age 4. RESULTS Parents of 865 children were called, 123 were excluded. Of 742 children enrolled, 601 underwent the entry orthoptic examination at age 14.5 ± 1.7 months. Mean SE was + 1.73 ± 1.18D, astigmatism -0.70 ± 0.44D, anisometropia 0.21D (IQR: 0-0.25). Of 62 (10.3%) children exceeding the Criteria, 52 were randomized into wearing glasses or not. Of 539 other children, 522 are followed up at CHCs. In total, 31 were excluded: 2 had strabismus and amblyopia, 7 strabismus, 2 amblyopia suspect, 1 strabismus suspect, 1 squinting during sinusitis, 4 excessive refractive error, 9 myopia, 2 ptosis, 1 oculomotor apraxia, 1 Duane syndrome, 1 congenital nystagmus. CONCLUSION Prevalence of strabismus (10/601) was as expected, but prevalence of amblyopia (2/601) was low, suggesting that common amblyopia develops later than generally thought. KEY MESSAGES What is known • High refractive errors cause amblyopia, but no study has determined the exact relationship between the kind and size of refractive error at age 1 and the risk to develop amblyopia, and assessed the protective effect of glasses in a controlled, population-based, longitudinal study. What is new • At baseline, 601 children received a full orthoptic examination followed by retinoscopy in cycloplegia at the age of 14.5 ± 1.7 months; 10.3% had high refractive error exceeding spherical equivalent > + 3.5D, > 1.5D astigmatism, > 1D oblique astigmatism or > 1.5D anisometropia. • The prevalence of amblyopia was lower (0.3%) than expected, suggesting that most amblyopia develops after the first year of life. • The prevalence of anisometropia, associated with amblyopia in older children, was low (0.8%).

Abstract
INTRODUCTION Patients who present with hemorrhage from pelvic fractures have an increased risk of mortality with prolonged time to intervention. Identifying risk factors associated with hemorrhage can expedite treatment. In this study we explore clinical and radiographic predictors for angiography in trauma patients with pelvic fractures. METHOD Retrospective, single-center review between 2009 and 2019 at a level 1 trauma center of all trauma patients with pelvic fractures. We excluded patients who died prior to arrival or in the trauma bay who did not undergo computed tomography ("CT"). Finalized attending descriptions of CT findings were reviewed, including size of hematomas, and presence of extravasation. Chi-square, Mann-Whitney U and multi-variate regressions were performed. RESULTS We analyzed 1,703 trauma patients with pelvic fractures. Most common mechanisms of injury included MVC (45 %), fall (27 %) and motorcycle accident (12 %). 48 % (819/1703) of patients had pelvic hematomas on CT scan. 17 %(138/819) of patients with a hematoma also had evidence of extravasation. Significant predictors for extravasation on CT included large hematoma on CT, AIS extremity ≥2, binder placement, increased ISS, HR, and decreased GCS and SBP (p < 0.005). Significant predictors for angiography were similar, including AIS extremity ≥2, binder placement, presence of moderate and large hematoma and active extravasation on CT (p < 0.01). Stepwise logistic regression model incorporated ISS, HR, AIS extremity score, binder placement, and contrast extravasation with an AUC = 0.9345. CONCLUSION In this large retrospective review of traumatic pelvic fractures, specific clinical and radiographic factors were significantly associated with pelvic hematomas, extravasation and/or need for angiography. Future collaborative work with orthopedics and interventional radiology is planned to better triage pelvic fracture patients and identify those at risk for bleeding that require earlier intervention.

Pediatr Pulmonol 2024.

Abstract
BACKGROUND The benefit of antibiotic treatment of acute drops in FEV1 percent predicted (FEV1pp) has been clearly established, but data from the early 2000s showed inconsistent treatment. Further, there is no empirical evidence for what magnitude of drop is clinically significant. METHODS We used data from the CF Foundation Patient Registry (CFFPR) from 2016 to 2019 to determine the association between treatment (any IV antibiotics, only oral or newly prescribed inhaled antibiotics, or no antibiotic therapy) following a decline of ≥5% from baseline FEV1pp and return to 100% baseline FEV1pp days using multivariable logistic regression including an interaction between the magnitude of decline and treatment category. RESULTS Overall, 16,495 PWCF had a decline: 16.5% were treated with IV antibiotics, 25.0% non-IV antibiotics, and 58.5% received no antibiotics. Antibiotic treatment was more likely for those with lower lung function, history of a positive PA culture, older age and larger FEV1 decline (p < 0.001). Treatment with IV antibiotics or oral/inhaled antibiotics was associated with a higher odds of recovery to baseline compared to no treatment across all levels of decline, including declines of 5%-10%. CONCLUSIONS A large proportion of acute drops in FEV1pp continue to be untreated, especially in younger patients and those with higher baseline lung function. Acute drops as small as 5% predicted are less likely to be recovered if antibiotic treatment is not prescribed. These findings suggest the need for more aggressive antimicrobial treatment of acute drops in FEV1, including those of a magnitude previously believed to be associated with self-recovery.

Abstract
BACKGROUND In cystic fibrosis (CF), pathophysiologic changes in the gastrointestinal tract lead to malnutrition and altered gut microbiome. Microbiome alterations have been linked to linear growth, gut inflammation and respiratory manifestations. Elucidating these gut microbiome alterations may provide insight into future nutritional management in CF. METHODS Infants were followed for 12-months at four sites in the United States (US-CF) and Australia (AUS-CF). 16S rRNA gene sequencing was performed on longitudinal stool samples. Associations between microbial abundance and age, antibiotic prophylaxis, malnutrition, and breast feeding were evaluated using generalized linear mixed models. Taxonomic and predictive functional features were compared between groups. RESULTS Infants with CF (N = 78) were enrolled as part of a larger study. AUS-CF infants had higher mean weight-for-age z-scores than US-CF infants (p = 0.02). A subset of participants (CF N = 40, non-CF disease controls N = 10) provided stool samples for microbiome analysis. AUS-CF infants had lower stool alpha diversity compared to US-CF infants (p < 0.001). AUS-CF infants had higher relative abundance of stool Proteobacteria compared to US-CF infants which was associated with antibiotic prophylaxis (p < 0.001). Malnutrition (weight-for-age <10th percentile) was associated with depleted Lactococcus (p < 0.001). Antibiotic prophylaxis (p = 0.002) and malnutrition (p = 0.012) were linked with predicted decreased activity of metabolic pathways responsible for short chain fatty acid processing. CONCLUSIONS In infants with CF, gut microbiome composition and diversity differed between the two continents. Gut microbial diversity was not linked to growth. The relationship between malnutrition and antibiotic prophylaxis with reduced SCFA fermentation could have implications for gut health and function and warrants additional investigation.

Abstract
Background Patients with celiac disease (CeD) reported increased COVID-19 vaccine hesitancy due to a fear of adverse events (AEs). However, the risk of AEs post-COVID-19 vaccination in patients with CeD is unknown. Purpose To assess whether the rate of common side effects (SEs) and AEs due to COVID vaccines are higher in patients with CeD compared to a non-CeD population. Method We conducted a collaborative international cross-sectional study in 16 countries between April 2022 and July 2022. An online survey was distributed to patients with CeD through patients’ local societies, and to non-CeD from the general population in each country through social media posts, word-of-mouth, and through academic institutions. We collected data on participant demographics, medical conditions, CeD diagnosis, GFD adherence, history of COVID-19 vaccinations (type and doses) and self-reported SEs and AEs post-COVID-19 vaccine. SEs included pain/swelling at the site, fatigue, fever, chills, nausea and/or headaches. AEs included thrombosis, myocarditis, anaphylactic reaction, and hospitalization related to the vaccine. Logistic regression models were used to assess predictors such as CeD diagnosis, age, gender, vaccine type and comorbidities on the likelihood of reporting SEs and AEs post-vaccine. Result(s) : A total of 17,795 participants completed the survey, 13,638 with CeD (median age of 45[27]) and 4,157 non-CeD controls (median age of 43[20]). There were no significant differences in sex between CeD and controls. Overall, CeD patients had similar odds of SEs compared with non-CeD individuals (aOR=1.02;95% CI=0.92-1.14). SEs were slightly increased only in the second dose of the vaccine in the CeD population compared to non-CeD individuals (aOR= 1.35; 95% CI=1.19-1.53). The most common reported SEs in CeD and controls were pain/swelling at the injection site (29% vs 23 %, p< 0.0001) and fatigue (29% vs 24%, p<0.0001). The odds of SEs were higher with Moderna Spikevax, AstraZeneca/Oxford and Johnson and Johnson vaccines than after the Pfizer vaccine (p< 0.0001). The overall rate of AEs post-vaccine was similar between patients with CeD and non-CeD individuals (aOR= 1.29; 95% CI= 0.89-1.87). Overall, female gender, older age, GFD adherence, respiratory conditions, obesity and receiving immunosuppressive medications increased the odds of SEs, while only age and a history of allergies increased the odds of AEs. Conclusion(s) In this large international study, patients with CeD reported similar rates of SEs and AEs post-COVID vaccine compared to non-CeD individuals. This information is highly relevant as it addresses the main concern leading to COVID-19 vaccine hesitancy in CeD patients. Disclosure of Interest None Declared

Abstract
Abstract
Aim
Incisional hernias are common and can significantly impact a patient's quality of life. Traditionally, abdominal wall reconstruction (AWR) has been performed by general surgeons, or those with special interest, often working in isolation. However, there is increasing awareness of pre-optimisation, risk stratification, enhanced training, and personalising treatment using a wide range of techniques.
Methods & Results
For complex and higher-risk procedures, Multidisciplinary team (MDT) management is considered the standard of care for optimising outcomes. The lack of standardised protocols and clear evidence in AWR means that surgical management can vary greatly. This makes the MDT process even more important due to the complexity of the decision-making involved. We describe a successful MDT process for complex abdominal wall reconstruction at a tertiary referral centre. Patients are reviewed at weekly AWR meetings with a multidisciplinary team, which includes consultants, advanced clinical practitioners and trainees. This is an opportunity for objective risk stratification, radiological review and assessment of the patient's goals before preoptimization and operative planning. Prospective data is collected on all patients to allow for quality improvement and service development.
Conclusion
MDT management of abdominal wall hernia is gaining popularity but remains poorly established in most regions. The involvement of surgical colleagues and other specialists is crucial in developing this growing field of surgery. We hope to expand our team to include Radiologists and Nutritionists, with the possibility of extending to regional networks, as we continue to explore new techniques and methods in managing complex abdominal wall hernias.

Abstract
BACKGROUND Cystic fibrosis (CF) pulmonary exacerbation (PEx) treatment guidelines suggest that Pseudomonas aeruginosa (Pa) airway infection be treated with two antipseudomonal agents. METHODS We retrospectively studied treatment responses for STOP2 PEx treatment trial (NCT02781610) participants with a history of Pa infection. Mean lung function and symptom changes from intravenous (IV) antimicrobial treatment start to Visit 2 (7 to 10 days later) were compared between those receiving one, two, and three+ antipseudomonal classes before Visit 2 by ANCOVA. Odds of PEx retreatment with IV antimicrobials within 30 days and future IV-treated PEx hazard were modeled by logistic and Cox proportional hazards regression, respectively. Sensitivity analyses limited to the most common one-, two-, and three-class regimens, to only IV/oral antipseudomonal treatments, and with more stringent Pa infection definitions were conducted. RESULTS Among 751 participants, 50 (6.7%) were treated with one antipseudomonal class before Visit 2, while 552 (73.5%) and 149 (19.8%) were treated with two and with three+ classes, respectively. Females and participants with a negative Pa culture in the prior month were more likely to be treated with a single class. The most common single, double, and triple class regimens were beta-lactam (BL; n = 42), BL/aminoglycoside (AG; n = 459), and BL/AG/fluoroquinolone (FQ; n = 73). No lung function or symptom response, odds of retreatment, or future PEx hazard differences were observed by number of antipseudomonal classes administered in primary or sensitivity analyses. CONCLUSIONS We were unable to identify additional benefit when multiple antipseudomonal classes are used to treat PEx in people with CF and Pa.

Abstract
BACKGROUND C-reactive protein (CRP) has been proposed as a biomarker for pulmonary exacerbation (PEx) diagnosis and treatment response. CRP >75mg/L has been associated with increased risk of PEx treatment failure. We have analyzed CRP measures as biomarkers for clinical response during the STOP2 PEx study (NCT02781610). METHODS CRP measures were collected at antimicrobial treatment start (V1), seven to 10 days later (V2), and two weeks after treatment end (V3). V1 log10CRP concentrations and log10CRP change from V1 to V3 correlations with clinical responses (changes in lung function and symptom score) were assessed by least squares regression. Odds of intravenous (IV) antimicrobial retreatment within 30 days and future PEx hazard associated with V1 and V3 CRP concentrations and V1 CRP >75 mg/L were studied by adjusted logistic regression and proportional hazards modeling, respectively. RESULTS In all, 951 of 982 STOP2 subjects (92.7%) had CRP measures at V1. V1 log10CRP varied significantly by V1 lung function subgroup, symptom score quartile, and sex, but not by age subgroup. V1 log10CRP correlated moderately with log10CRP change at V3 (r2=0.255) but less so with lung function (r2=0.016) or symptom (r2=0.031) changes at V3. Higher V1 CRP was associated with greater response. CRP changes from V1 to V3 only weakly correlated with lung function (r2=0.061) and symptom (r2=0.066) changes. However, V3 log10CRP was associated with increased odds of retreatment (P = .0081) and future PEx hazard (P = .0114). DISCUSSION Despite consistent trends, log10CRP change was highly variable with only limited utility as a biomarker of PEx treatment response.

Abstract
The lung clearance index (LCI) measured by the multiple breath washout (MBW) test is sensitive to early lung disease in children with cystic fibrosis. While LCI worsens during the preschool years in cystic fibrosis, there is limited evidence to clarify whether this continues during the early school age years, and whether the trajectory of disease progression as measured by LCI is modifiable.A cohort of children (healthy and cystic fibrosis) previously studied for 12 months as preschoolers were followed during school age (5-10 years). LCI was measured every 3 months for a period of 24 months using the Exhalyzer D MBW nitrogen washout device. Linear mixed effects regression was used to model changes in LCI over time.A total of 582 MBW measurements in 48 healthy subjects and 845 measurements in 64 cystic fibrosis subjects were available. The majority of children with cystic fibrosis had elevated LCI at the first preschool and first school age visits (57.8% (37 out of 64)), whereas all but six had normal forced expiratory volume in 1 s (FEV1) values at the first school age visit. During school age years, the course of disease was stable (-0.02 units·year-1 (95% CI -0.14-0.10). LCI measured during preschool years, as well as the rate of LCI change during this time period, were important determinants of LCI and FEV1, at school age.Preschool LCI was a major determinant of school age LCI; these findings further support that the preschool years are critical for early intervention strategies.

Abstract
Abstract
Background
The British Columbia Colon Screening Program (BCCSP) is a population-based program enrolling 50–74 year old individuals for biennial FIT (OC-Sensor, cut-off 10 mcg/g) with follow-up colonoscopy for positive FIT. The neoplasia detection rate is 50–55% and over 75% of colonoscopies have a specimen taken. Previously reported colonoscopy adverse event rates for FIT based screening programs vary widely: 0.03–6.2% and 0–2.7% for bleeding and perforation, respectively. Mortality as a result of colonoscopy is rare but has been reported in 0.0004%-0.0074% of colonoscopies. The rate of colonoscopy related adverse events in BCCSP participants is unknown.
Aims
To determine the rate of colonoscopy related serious adverse events within the BCCSP.
Methods
This is a retrospective cohort study of all participants undergoing colonoscopy in BCCSP from November 15, 2013 to December 31, 2017. BCCSP contacts screening participants by phone 14 days post colonoscopy to determine unplanned medical visits the day prior (during bowel preparation) or following the colonoscopy. Unplanned events underwent chart review if the event was a perforation, cardiovascular or respiratory event, or resulted in death, hospitalization, or significant intervention including repeat colonoscopy, interventional radiology, surgery, blood transfusion, cardioversion, casting of a fracture or suturing of a laceration. Chart review was conducted by a Colonoscopy Lead and reviewed by BCCSP Quality Committee. Unplanned events were defined as serious adverse events (SAE) if they resulted in death, hospitalization or significant intervention and further classified as probably, possibly, or unlikely related to the colonoscopy.
Results
A total of 108,004 colonoscopies were performed. Unplanned events were reported in 1753 participants, of which 586 met criteria for review. Of these, 578 were confirmed unplanned events and 409 were SAEs of which 367 (89.7%) were probably, 22 (5.4%) possibly and 20 (4.9%) unlikely associated with colonoscopy. 36/10,000 colonoscopies were associated with a SAE that was probably or possibly related: perforation in 5/10,000, bleeding 22/10,000. Three deaths occurred in the 14 days following colonoscopy that were probably (2 perforations) or possibly related to the colonoscopy (0.3/10,000).
Conclusions
The BCCSP has a colonoscopy SAE rate in keeping with previous publications, particularly in the context of a very high proportion of procedures associated with polypectomy, a known risk factor for perforation and bleeding. This study will help inform screening participants about the risks of colonoscopy in the BC program. Future studies are required to confirm these rates using hospital admission data.

Abstract
Abstract
Background
Colorectal Cancer (CRC) mortality is significantly higher after a lung transplant (1). CRC screening for average risk patients in British Columbia is done with Fecal Immunochemical Testing (FIT) every two years (2), however colonoscopy is currently the standard modality in patients undergoing lung transplant assessments in British Columbia. The yield of using FITs or Fecal Occult Blood Testing (FOBT) and colonoscopy in screening for lung transplant assessments in Canada is unknown.
Aims
To review the colon cancer screening results for all lung transplants done in British Columbia from 2013 to 2018.
Methods
This is a retrospective chart review of the 222 lung transplants done from January 2013 to December 2019.
Results
220 patients were transplanted during this time period. 2 patients were re-transplanted. 136 of the 220 lung transplant patients were male (62%). The most common indication for transplantation was interstitial lung disease (44%), followed by chronic obstructive pulmonary disease (30%), cystic fibrosis (7%), and pulmonary hypertension (4%). Colonoscopies were performed in 127 of the 220 patients. Computed tomography (CT) colonography was performed in 15 of the 220 patients, and a FOBT or FIT was performed in 200 of the 220 patients. No colon cancers were found by colonoscopy or CT colonography (0/142). Of the colonoscopies performed, 38 % (49/127) had adenomatous or serrated polyps removed. Of these 36% (18/49) had high risk pathology. The positive predictive value of a FIT/FOBT positive for a polyp was 51.4 % (CI 37.6–65.1%).
Conclusions
The value of non-invasive screening modalities in pre-lung transplant patients are modest. Program screening should be tailored to the lung transplant candidate’s risk of CRC and the risk of an invasive procedure with a known complication rate.
