Where public health meets public opinion: Understanding political support for fluoridation in Calgary, 2021.

Objectives: To understand variables associated with support for community water fluoridation among ordinary citizens during periods of heightened issue salience, with a particular focus on how support varies on the basis of demographic characteristics, attitudes toward public health science, and political variables such as ideology, populism, and issue salience.

Methods: Statistical analysis of individual-level data from a large-scale survey of eligible voters in the City of Calgary, Alberta in 2021, collected at the time of a community water fluoridation plebiscite.

Results: Survey data (N = 1130) reveal substantively important and statistically significant relationships with fluoridation support in each of our three analysis categories (demographics, public health expertise, and politics).

Prevalence and spectrum of manifestations of tamoxifen retinopathy as assessed by multimodal and ultra-widefield retinal imaging.

Background/objectives: Tamoxifen has well-known retinal toxicity, but the epidemiology of this toxicity is poorly defined. This study aims to 1) evaluate the prevalence of tamoxifen retinopathy in a major northeastern metropolitan area based on multimodal retinal imaging and 2) determine whether the additional peripheral retina captured in ultra-widefield (UWF) imaging aids in the diagnosis of tamoxifen retinopathy.

Methods: This retrospective cohort study examined female patients initiated on tamoxifen for at least 12 months prior to their first retinal exam.

Adverse Events Associated With 3 Vitrectomy Platforms Reported to the US FDA MAUDE Database.

To identify and describe adverse events (AEs) observed with real-world use of the following 3 vitrectomy platforms: Constellation (Alcon), Enhancing Visual Acuity (EVA, Dutch Ophthalmic Research Center), and Stellaris (Bausch + Lomb). All reports submitted to the US Food and Drug Administration's Manufacturer and User Facility Device Experience (MAUDE) database between January 2010 and November 2021 that were associated with the 3 vitrectomy platforms were analyzed. Each report was reviewed for AEs or consequences and the type of complication noted.

PREVALENCE OF DIDANOSINE-RELATED RETINAL TOXICITY AT AN URBAN ACADEMIC CENTER AS DIAGNOSED WITH ULTRA-WIDEFIELD IMAGING.

Purpose: Antiretroviral therapy has revolutionized HIV treatment with didanosine (DDI) as a pioneering drug. However, DDI has been associated with retinal toxicity, characterized by peripheral chorioretinal degeneration with macular sparing. Despite its clinical recognition, the prevalence and risk factors for didanosine-induced retinopathy are not well described.

Diagnosis and stabilisation of familial chylomicronemia syndrome in two infants presenting with hypertriglyceridemia-induced acute pancreatitis.

Familial chylomicronemia syndrome (FCS) is a rare disorder of triglyceride (TG) metabolism caused by loss of function variants in one of five known canonical genes involved in chylomicron lipolysis and clearance-, , , , and . Pathogenic variants in , which encodes the hydrolytic enzyme lipoprotein lipase, account for over 80%-90% of cases. FCS may present in infancy with hypertriglyceridemia-induced acute pancreatitis and is challenging to manage both acutely and in the long-term.

Prevalence of Age-Related Macular Degeneration in Patients with Chronic Exposure to P2X7R Inhibitors.

Purpose: P2X7 receptor (P2X7R) is a purinergic cation channel whose activation has been linked with age-related macular degeneration (ARMD). Several nucleoside reverse transcriptase inhibitors, zidovudine (AZT), lamivudine (3TC) and abacavir (ABC), have been shown to inhibit P2X7R and improve outcomes in animal models of ARMD. Our aim is to investigate the association between chronic AZT, 3TC, and ABC therapy and ARMD in a clinical setting.

Post-diagnosis adiposity and colorectal cancer prognosis: A Global Cancer Update Programme (CUP Global) systematic literature review and meta-analysis.

The adiposity influence on colorectal cancer prognosis remains poorly characterised. We performed a systematic review and meta-analysis on post-diagnosis adiposity measures (body mass index [BMI], waist circumference, waist-to-hip ratio, weight) or their changes and colorectal cancer outcomes. PubMed and Embase were searched through 28 February 2022.

Post-diagnosis physical activity and sedentary behaviour and colorectal cancer prognosis: A Global Cancer Update Programme (CUP Global) systematic literature review and meta-analysis.

Low physical activity and high sedentary behaviour have been clearly linked with colorectal cancer development, yet data on their potential role in colorectal cancer survival is limited. Better characterisation of these relationships is needed for the development of post-diagnosis physical activity and sedentary behaviour guidance for colorectal cancer survivors. We searched PubMed and Embase through 28 February 2022 for studies assessing post-diagnosis physical activity, and/or sedentary behaviour in relation to all-cause and cause-specific mortality and recurrence after colorectal cancer diagnosis.

Post-diagnosis dietary factors, supplement use and colorectal cancer prognosis: A Global Cancer Update Programme (CUP Global) systematic literature review and meta-analysis.

The role of diet in colorectal cancer prognosis is not well understood and specific lifestyle recommendations are lacking. We searched for randomised controlled trials (RCTs) and longitudinal observational studies on post-diagnosis dietary factors, supplement use and colorectal cancer survival outcomes in PubMed and Embase from inception until 28th February 2022. Random-effects dose-response meta-analyses were conducted when at least three studies had sufficient information.

Prognostic impact of the IASLC grading system of lung adenocarcinoma: a systematic review and meta-analysis.

Aims: Tumour grading is an essential part of the pathologic assessment that promotes patient management. The International Association for the Study of Lung Cancer (IASLC) proposed a grading system for non-mucinous lung adenocarcinoma in 2020. We aimed to validate the prognostic impact of this novel grading system on overall survival (OS) and recurrence-free survival (RFS) based on literature data.

Evidence-Based Use of Bevacizumab in the Management of Neovascular Age-Related Macular Degeneration.

Indicated for colorectal cancer for decades, bevacizumab has been widely used off label to treat retinal diseases, and the benefits of its use, specifically in neovascular age-related macular degeneration, have been demonstrated in multiple clinical trials. The intravitreal delivery of bevacizumab requires it to be aseptically repackaged into individual syringes by compounding pharmacies for use in the eye. Although the repackaging process is permitted by the US Food and Drug Administration, the resultant product does not meet the specific standards of products approved for use as ophthalmic injectables nor is the parenteral innovator solution compliant with ophthalmic standards.

Incidence of Blepharoptosis Following Intravitreal Anti-Vascular Endothelial Growth Factor Injections.

Purpose: To determine the incidence of blepharoptosis after intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections and compare the rates of blepharoptosis between patients injected with an eyelid speculum and those injected without a speculum.

Design: Retrospective cohort study.

Methods: International Classification of Diseases, Tenth Revision (ICD-10), codes were used to identify patients with exudative age-related macular degeneration (AMD) and those who developed ptosis after intravitreal injections.

Implementation of a Teleophthalmology Screening Program for Diabetic Retinopathy in New York City.

To examine the implementation of a teleophthalmology program for diabetic retinopathy (DR) screening at a metropolitan hospital system and identify the challenges that the clinical teams encountered using the program. The study was conducted in 2 parts. The first was a pilot retrospective chart review of 300 consecutive patients screened for DR by the teleophthalmology screening program.

Safety and efficacy of ixoberogene soroparvovec in neovascular age-related macular degeneration in the United States (OPTIC): a prospective, two-year, multicentre phase 1 study.

Background: Gene therapy, successfully used in rare, monogenetic disorders, may prove to be a durable management approach for common, polygenetic conditions, including neovascular age-related macular degeneration (nAMD). Repeated injections, oftentimes monthly, and possibly for decades, of vascular endothelial growth factor antagonists (anti-VEGF), is the standard for nAMD. We hypothesised that an in-office, intravitreal administration of ixoberogene soroparvovec (ixo-vec, formerly ADVM-022), a single-dose gene therapy encoding for the proven anti-VEGF protein, aflibercept, would transform retinal cells to continually produce aflibercept to minimise treatment burden in nAMD.

Role of CB1 Cannabinoid Receptors in Vascular Responses and Vascular Remodeling of the Aorta in Female Mice.

Both the endocannabinoid system (ECS) and estrogens have significant roles in cardiovascular control processes. Cannabinoid type 1 receptors (CBRs) mediate acute vasodilator and hypotensive effects, although their role in cardiovascular pathological conditions is still controversial. Estrogens exert cardiovascular protection in females.

Objective: The aim of our work was the Hungarian translation and cultural adaptation of the questionnaire and also validation of the CPCHILD on Hungarian cerebral palsy patients. Further aim was to test the eligibility of the questionnaire for superficial assessment of caregiver's psychological attitudes.

Gut Region-Specific Interleukin 1β Induction in Different Myenteric Neuronal Subpopulations of Type 1 Diabetic Rats.

Interleukin 1β (IL1β) is a pro-inflammatory cytokine that may play a crucial role in enteric neuroinflammation in type 1 diabetes. Therefore, our goal is to evaluate the effects of chronic hyperglycemia and insulin treatment on IL1β immunoreactivity in myenteric neurons and their different subpopulations along the duodenum-ileum-colon axis. Fluorescent immunohistochemistry was used to count IL1β expressing neurons as well as the neuronal nitric oxide synthase (nNOS)- and calcitonin gene-related peptide (CGRP)-immunoreactive myenteric neurons within this group.

A cryptic pathogenic NDUFV1 variant identified by RNA-seq in a patient with normal complex I activity in muscle and transient magnetic resonance imaging changes.

Mitochondrial respiratory chain disorders (MRC) are amongst the most common group of inborn errors of metabolism. MRC, of which complex I deficiency accounts for approximately a quarter, are very diverse, causing a wide range of clinical problems and can be difficult to diagnose. We report an illustrative MRC case whose diagnosis was elusive.

Co-occurrence of neurofibromatosis type 1 and pseudoachondroplasia - a first case report.

Background: Neurofibromatosis type 1 and pseudoachondroplasia are both rare autosomal dominant disorders, caused by pathogenic mutations in NF1 and COMP genes, respectively. Both neurofibromin 1 and cartilage oligomeric matrix protein (COMP) play a role in the development of the skeleton. Carrying both germline mutations has not been previously reported; however, it can affect the developing phenotype.
