Cognitive Impairment in the Primary Care Clinic.

Cognitive impairment is a common problem in the geriatric population and is characterized by variable symptoms of memory difficulties, executive dysfunction, language or visuospatial problems, and behavioral changes. It is imperative that primary care clinicians recognize and differentiate the variable symptoms associated with cognitive impairment from changes attributable to normal aging or secondary to other medical conditions. A thorough evaluation for potentially reversible causes of dementia is required before diagnosis with a neurodegenerative dementia. Other abnormal neurologic findings, rapid progression, or early age of onset are red flags that merit referral to neurology for more specialized evaluation and treatment.

Hypertension and Kidney Function After Living Kidney Donation.

Importance: Recent guidelines call for better evidence on health outcomes after living kidney donation. Objective: To determine the risk of hypertension in normotensive adults who donated a kidney compared with nondonors of similar baseline health. Their rates of estimated glomerular filtration rate (eGFR) decline and risk of albuminuria were also compared. Design, Setting, and Participants: Prospective cohort study of 924 standard-criteria living kidney donors enrolled before surgery and a concurrent sample of 396 nondonors. Recruitment occurred from 2004 to 2014 from 17 transplant centers (12 in Canada and 5 in Australia); follow-up occurred until November 2021. Donors and nondonors had the same annual schedule of follow-up assessments. Inverse probability of treatment weighting on a propensity score was used to balance donors and nondonors on baseline characteristics. Exposure: Living kidney donation. Main Outcomes and Measures: Hypertension (systolic blood pressure [SBP] ≥140 mm Hg, diastolic blood pressure [DBP] ≥90 mm Hg, or antihypertensive medication), annualized change in eGFR (starting 12 months after donation/simulated donation date in nondonors), and albuminuria (albumin to creatinine ratio ≥3 mg/mmol [≥30 mg/g]). Results: Among the 924 donors, 66% were female; they had a mean age of 47 years and a mean eGFR of 100 mL/min/1.73 m2. Donors were more likely than nondonors to have a family history of kidney failure (464/922 [50%] vs 89/394 [23%], respectively). After statistical weighting, the sample of nondonors increased to 928 and baseline characteristics were similar between the 2 groups. During a median follow-up of 7.3 years (IQR, 6.0-9.0), in weighted analysis, hypertension occurred in 161 of 924 donors (17%) and 158 of 928 nondonors (17%) (weighted hazard ratio, 1.11 [95% CI, 0.75-1.66]). The longitudinal change in mean blood pressure was similar in donors and nondonors. After the initial drop in donors' eGFR after nephrectomy (mean, 32 mL/min/1.73 m2), donors had a 1.4-mL/min/1.73 m2 (95% CI, 1.2-1.5) per year lesser decline in eGFR than nondonors. However, more donors than nondonors had an eGFR between 30 and 60 mL/min/1.73 m2 at least once in follow-up (438/924 [47%] vs 49/928 [5%]). Albuminuria occurred in 132 of 905 donors (15%) and 95 of 904 nondonors (11%) (weighted hazard ratio, 1.46 [95% CI, 0.97-2.21]); the weighted between-group difference in the albumin to creatinine ratio was 1.02 (95% CI, 0.88-1.19). Conclusions and Relevance: In this cohort study of living kidney donors and nondonors with the same follow-up schedule, the risks of hypertension and albuminuria were not significantly different. After the initial drop in eGFR from nephrectomy, donors had a slower mean rate of eGFR decline than nondonors but were more likely to have an eGFR between 30 and 60 mL/min/1.73 m2 at least once in follow-up.

One-Year Anti-VEGF Therapy Outcomes in Diabetic Macular Edema Based on Treatment Intensity: Data from the Fight Retinal Blindness! Registry.

PURPOSE: To compare 1-year outcomes of eyes with diabetic macular edema (DME) treated in routine clinical practice based on the proportion of visits where intravitreal VEGF inhibitor injections were delivered. DESIGN: Cohort study. PARTICIPANTS: There were 2288 treatment-naive eyes with DME starting intravitreal VEGF inhibitor therapy from October 31, 2015 to October 31, 2021 from the Fight Retinal Blindness! international outcomes registry. METHODS: Eyes were grouped according to the proportion of visits at which an injection was received, Group A with less than the median of 67% (n = 1172) versus Group B with greater than the median (n = 1116). MAIN OUTCOME MEASURES: Mean visual acuity (VA) change after 12 months of treatment. RESULTS: The mean (95% confidence interval [CI]) VA change after 12 months of treatment was 3.6 (2.8-4.4) letters for eyes in Group A versus 5.2 (4.4-5.9) letters for eyes in Group B (P = 0.005). The mean (95% CI) central subfield thickness (CST) change was -69 (-76 to -61) µm and -85 (-92 to -78) µm for eyes in Group A versus Group B, respectively (P = 0.002). A moderate positive correlation was observed between the number of injections received over 12 months of treatment and the change in VA (P < 0.001). Additionally, eyes that received more injections had a moderately greater CST reduction. CONCLUSIONS: This registry analysis found that overall VA and anatomic outcomes tended to be better in DME eyes treated at a greater proportion of visits in the first year of intravitreal VEGF inhibitor therapy.

Advanced imaging and modeling in neonatal simulation.

Advances in modeling and imaging have resulted in realistic tools that can be applied to education and training, and even direct patient care. These include point-of-care ultrasound (POCUS), 3-dimensional and digital anatomic modeling, and extended reality. These technologies have been used for the preparation of complex patient care through simulation-based clinical rehearsals, direct patient care such as the creation of patient devices and implants, and for simulation-based education and training for health professionals, patients and families. In this section, we discuss these emerging technologies and describe how they can be utilized to improve patient care.

Dexamethasone intravitreal implant in diabetic macular oedema refractory to anti-vascular endothelial growth factors: the AUSSIEDEX study.

AIM: To evaluate effectiveness of dexamethasone intravitreal implant 0.7 mg (DEX) monotherapy in the AUSSIEDEX study non-responder subgroup, defined by diabetic macular oedema (DME) refractory to anti-vascular endothelial growth factor (anti-VEGF) agents. METHODS: This prospective, open-label, observational, real-world study included pseudophakic and phakic (scheduled for cataract surgery) eyes that did not achieve a ≥5-letter best corrected visual acuity (BCVA) gain and/or clinically significant central subfield retinal thickness (CRT) improvement after 3-6 anti-VEGF injections for DME (N=143 eyes), regardless of baseline BCVA and CRT. After an initial DEX injection (baseline visit), reinjection was permitted at ≥16-week intervals. PRIMARY ENDPOINTS: changes in mean BCVA and CRT from baseline to week 52. Safety assessments included adverse events. RESULTS: Of 143 eyes, 53 (37.1%) and 89 (62.2%) switched to DEX after 3-6 (early) and >6 (late) anti-VEGF injections, respectively; 1 (0.7%) had missing information. With 2.3 injections (mean) over 52 weeks, the change in mean BCVA from a baseline of 57.8 letters was not significant at week 52. Mean CRT improved significantly from a baseline of 417.8 µm at week 52 (mean change -60.9 µm; p<0.001). Outcomes were similar in eyes switched to DEX early and late. No unexpected adverse events were reported; no filtration surgeries were required. CONCLUSION: To date, AUSSIEDEX is the largest prospective, real-world study of DEX monotherapy for treatment-naïve or anti-VEGF-refractory DME. Following early or late switch from anti-VEGF agents, DEX significantly improved anatomic outcomes at 52 weeks without new safety concerns, supporting use in anti-VEGF-refractory DME. TRIAL REGISTRATION NUMBER: NCT02731911.

Learning the statistics of pronoun reference: By word or by category?

Evidence shows that readers tend to follow recently-encountered patterns for interpreting ambiguous pronouns. If recent exposure includes frequent pronouns with prepositional object antecedents (e.g., "Matt went to the library with Ana. She took out a book"), people adapt and are more likely to assign ambiguous pronouns to prepositional antecedents than if they were exposed to pronouns with subject antecedents (Johnson & Arnold, 2022). However, it is unclear how people categorize different referential structures and how broadly they make generalizations. Johnson and Arnold (2022) found that people can learn a referential relationship specific to third-person pronouns and an antecedent's syntactic or thematic properties. The current study uses this paradigm to test how broadly people generalize categories of different types of pronouns and antecedents. Do people adapt to the behavior of categorizing "he" and "she" as individual words, or as a general class? (Experiment 1). Do people learn about likely antecedents for pronouns separately for different verb constructions (transfer vs. joint-action) and thematic roles, or broadly by grammatical function? (Experiments 2 & 3). Participants were repeatedly exposed to a referential structure of a particular type of pronouns or antecedents, and then were tested on ambiguous pronouns. All experiments showed that pronoun adaptation generalizes to new instances from the broad categorization of pronouns and antecedents.

Videolaryngoscopy versus direct laryngoscopy for tracheal intubation in neonates.

BACKGROUND: Establishment of a secure airway is a critical part of neonatal resuscitation in the delivery room and the neonatal intensive care unit. Videolaryngoscopy has the potential to facilitate successful endotracheal intubation, and decrease adverse consequences of a delay in airway stabilization. Videolaryngoscopy may enhance visualization of the glottis and intubation success in neonates. This is an update of a review first published in 2015, and updated in 2018. OBJECTIVES: To determine the effectiveness and safety of videolaryngoscopy compared to direct laryngoscopy in decreasing the time and attempts required for endotracheal intubation and increasing the success rate on first intubation attempt in neonates (0 to 28 days of age). SEARCH METHODS: In November 2022, we updated the search for trials evaluating videolaryngoscopy for neonatal endotracheal intubation in CENTRAL, MEDLINE, Embase, CINAHL, and BIOSIS. We also searched abstracts of the Pediatric Academic Societies, clinical trials registries (www. CLINICALTRIALS: gov; www.controlled-trials.com), and reference lists of relevant studies. SELECTION CRITERIA: Randomized controlled trials (RCTs), quasi-RCTs, cluster-RCTs, or cross-over trials, in neonates (0 to 28 days of age), evaluating videolaryngoscopy with any device used for endotracheal intubation compared with direct laryngoscopy. DATA COLLECTION AND ANALYSIS: Three review authors performed data collection and analysis, as recommended by Cochrane Neonatal. Two review authors independently assessed studies identified by the search strategy for inclusion. We used the GRADE approach to assess the certainty of the evidence. MAIN RESULTS: The updated search yielded 7786 references, from which we identified five additional RCTs for inclusion, seven ongoing trials, and five studies awaiting classification. Three studies were included in the previous version of the review. For this update, we included eight studies, which provided data on 759 intubation attempts in neonates. We included neonates of either sex, who were undergoing endotracheal intubation in international hospitals. Different videolaryngoscopy devices (including C-MAC, Airtraq, and Glidescope) were used in the studies. For the primary outcomes; videolaryngoscopy may not reduce the time required for successful intubation when compared with direct laryngoscopy (mean difference [MD] 0.74, 95% confidence interval [CI] -0.19 to 1.67; 5 studies; 505 intubations; low-certainty evidence). Videolaryngoscopy may result in fewer intubation attempts (MD -0.08, 95% CI -0.15 to 0.00; 6 studies; 659 intubations; low-certainty evidence). Videolaryngoscopy may increase the success of intubation at the first attempt (risk ratio [RR] 1.24, 95% CI 1.13 to 1.37; risk difference [RD] 0.14, 95% CI 0.08 to 0.20; number needed to treat for an additional beneficial outcome [NNTB] 7, 95% CI 5 to 13; 8 studies; 759 intubation attempts; low-certainty evidence).  For the secondary outcomes; the evidence is very uncertain about the effect of videolaryngoscopy on desaturation or bradycardia episodes, or both, during intubation (RR 0.94, 95% CI 0.38 to 2.30; 3 studies; 343 intubations; very-low certainty evidence). Videolaryngoscopy may result in little to no difference in the lowest oxygen saturations during intubation compared with direct laryngoscopy (MD -0.76, 95% CI -5.74 to 4.23; 2 studies; 359 intubations; low-certainty evidence). Videolaryngoscopy likely results in a slight reduction in the incidence of airway trauma during intubation attempts compared with direct laryngoscopy (RR 0.21, 95% CI 0.05 to 0.79; RD -0.04, 95% CI -0.07 to -0.01; NNTB 25, 95% CI 14 to 100; 5 studies; 467 intubations; moderate-certainty evidence). There were no data available on other adverse effects of videolaryngoscopy. We found a high risk of bias in areas of allocation concealment and performance bias in the included studies. AUTHORS' CONCLUSIONS: Videolaryngoscopy may increase the success of intubation on the first attempt and may result in fewer intubation attempts, but may not reduce the time required for successful intubation (low-certainty evidence). Videolaryngoscopy likely results in a reduced incidence of airway-related adverse effects (moderate-certainty evidence). These results suggest that videolaryngoscopy may be more effective and potentially reduce harm when compared to direct laryngoscopy for endotracheal intubation in neonates. Well-designed, adequately powered RCTS are necessary to confirm the efficacy and safety of videolaryngoscopy in neonatal intubation.

Pediatric intraoperative cardiopulmonary arrests: A survey to evaluate if Medical Emergency Teams are utilized in pediatric operating rooms.

BACKGROUND: Studies have shown that standardized code teams may improve outcomes following cardiac arrests. Pediatric intra-operative cardiac arrests are rare events and are associated with a mortality rate of 18%. There is limited data available regarding use Medical Emergency Team (MET) response to pediatric intra-operative cardiac arrest. The purpose of this study was to identify the use of MET in response to pediatric intraoperative cardiac arrest as an exploratory step in establishing evidence-based standardized practice across the hospital for training and management of this rare event. METHODS: An anonymous electronic survey was created and sent to two populations: The Pediatric Anesthesia Leadership Council, a section of the Society for Pediatric Anesthesia, and the Pediatric Resuscitation Quality Collaborative, a multinational collaborative group, which works to improve resuscitation care in children. Standard summary and descriptive statistics were used for survey responses. RESULTS: The overall response rate was 41%. The majority of respondents worked in a university affiliated, free-standing children's hospital. Ninety-five percent of respondents had a dedicated pediatric MET at their hospital. In 60% of responses from Pediatric Resuscitation Quality Collaborative and 18% of Pediatric Anesthesia Leadership Council hospitals, the MET responds to pediatric intra-operative cardiac arrest; however, the majority of times MET involvement is requested rather than automatic. The MET was found to be activated intraoperatively for situations other than cardiac arrest such as, massive transfusion events, need for extra staff, and for specialty expertise. In 65% of institutions, simulation-based training for cardiac arrest is supported but lacking pediatric intra-operative focus. CONCLUSIONS: This survey revealed heterogeneity in the composition and response of the medical response teams responding to pediatric intra-operative cardiac arrests. Improved collaboration and cross training among MET, anesthesia, and operating room nursing may improve outcomes of pediatric intra-operative code events.

Diabetic Macular Oedema Guidelines: An Australian Perspective.

The number of people living with diabetes is expected to rise to 578 million by 2030 and to 700 million by 2045, exacting a severe socioeconomic burden on healthcare systems around the globe. This is also reflected in the increasing numbers of people with ocular complications of diabetes (namely, diabetic macular oedema (DMO) and diabetic retinopathy (DR)). In one study examining the global prevalence of DR, 35% of people with diabetes had some form of DR, 7% had PDR, 7% had DMO, and 10% were affected by these vision-threatening stages. In many regions of the world (Australia included), DR is one of the top three leading causes of vision loss amongst working age adults (20-74 years). In the management of DMO, the landmark ETDRS study demonstrated that moderate visual loss, defined as doubling of the visual angle, can be reduced by 50% or more by focal/grid laser photocoagulation. However, over the last 20 years, antivascular endothelial growth factor (VEGF) and corticosteroid therapies have emerged as alternative options for the management of DMO and provided patients with choices that have higher chances of improving vision than laser alone. In Australia, since the 2008 NHMRC guidelines, there have been significant developments in both the treatment options and treatment schedules for DMO. This working group was therefore assembled to review and address the current management options available in Australia.

Dexamethasone intravitreal implant in treatment-naïve diabetic macular oedema: findings from the prospective, multicentre, AUSSIEDEX study.

AIM: To evaluate the effectiveness of dexamethasone intravitreal implant 0.7 mg (DEX; Ozurdex) monotherapy in the patient subgroup of the AUSSIEDEX study with treatment-naïve diabetic macular oedema (DME). METHODS: The open-label, prospective, phase 4, real-world study included pseudophakic eyes and phakic eyes scheduled for cataract surgery that were treatment-naïve or non-responsive to antivascular endothelial growth factors. No eyes were excluded based on baseline best-corrected visual acuity (BCVA) or central subfield retinal thickness (CRT). After the initial DEX injection at the baseline visit, reinjection was permitted at ≥16-week intervals. Week-16 and week-52 visits were mandatory. Primary endpoints were changes in mean BCVA and CRT from baseline to 52 weeks. RESULTS: Of 200 eyes enrolled in the AUSSIEDEX study, 57 were treatment-naïve. Baseline mean BCVA was 58.8 letters and baseline mean CRT was 418.6 µm; changes in mean BCVA and CRT from baseline to 52 weeks in this subgroup were 3.4 letters (p=0.042) and -89.6 µm (p<0.001), respectively, with a mean 2.5 injections. The change in mean CRT from baseline was -55.8 µm at week 16 (p<0.001). The most common adverse event was increased intraocular pressure (IOP), with 20.0% of eyes requiring IOP-lowering medication. One patient was discontinued due to increased IOP. No eyes required filtration surgery. No serious, treatment-related ocular adverse events were reported. CONCLUSION: In this largest prospective, real-world study of DEX monotherapy for DME to date, DEX significantly improved CRT and BCVA at 52 weeks in treatment-naïve eyes, without new safety concerns, supporting DEX use in treatment-naïve DME. TRIAL REGISTRATION NUMBER: NCT02731911.

Changes in 12-month outcomes over time for age-related macular degeneration, diabetic macular oedema and retinal vein occlusion.

OBJECTIVES: To identify whether the outcomes of neovascular age-related macular degeneration (nAMD), diabetic macular oedema (DMO) and retinal vein occlusion (RVO) in routine clinical practice have changed over time. METHODS: We analysed 12-month outcomes in treatment-naïve eyes that started aflibercept or ranibizumab for nAMD (3802 eyes), DMO (975 eyes), Branch RVO (BRVO, 357 eyes), Central RVO (CRVO, 371 eyes) and Hemi-RVO (HRVO, 54 eyes) from 2015 and 2019 tracked in the prospectively designed observational Fight Retinal Blindness! Registry. RESULTS: The mean VA change at 12-month for each year between 2015 and 2019 remained stable or otherwise showed no discernible trends over time in eyes with nAMD (+3.3 to +6 letters), DMO (+3.6 to +6.7 letters) and RVO (+10.3 to +11.7 letters for BRVO, +5.9 to +17.7 letters for CRVO and 10.2 to 20.7 letters for HRVO). The median number of VEGF-inhibitor injections in eyes that completed 12-month follow-up also remained stable at 8-9 for nAMD, 6-7 for DMO, 7-9 for RVO. Fewer eyes (

The frequency of referential patterns guides pronoun comprehension.

There is extensive evidence that people are sensitive to the statistical patterns of linguistic elements at the phonological, lexical, and syntactic levels. However, much less is known about how people classify referential events and whether they adapt to the most frequent types of references. Reference is particularly complex because referential tokens can be multiply categorized, raising questions about what can be learned through referential exposure. We test the role of linguistic exposure to referential patterns in five experiments on pronoun comprehension, examining linguistic contexts like "X is doing something with Y" (Experiments 1a, b, and c) and transfer events like "X gave something to Y" (Experiments 2a and b). We ask whether the interpretation of ambiguous he or she pronouns is influenced by recent exposure and find that indeed it is, supporting the hypothesis that adaptation affects discourse processing. In Experiment 1, we further ask whether adaptation persists across three types of referring expressions (he or she pronouns, I/you pronouns, and names) and find that it is limited to he or she pronouns. In Experiment 2, we test whether people can learn both syntactically conditioned and semantically conditioned frequency patterns with transfer verbs. Results showed that they learned both patterns. These results provide critical new evidence that discourse processing biases are informed by exposure to referential patterns. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Longer treatment intervals are associated with reduced treatment persistence in neovascular age related macular degeneration.

AIMS: To test the hypothesis that patients treated for neovascular age related macular degeneration (nAMD) with longer treatment intervals are more likely to persist with treatment. METHODS: Data were obtained from the prospectively-defined Fight Retinal Blindness! registry. Treatment interval at 2 years was stratified based on the mean treatment interval over the three visits prior to and including the 2-year visit. Rates of non-persistence to follow-up were assessed from 2 to 5 years. RESULTS: Data from 1538 eyes were included. The overall rate of non-persistence was 51% at 5 years. Patients on longer treatment intervals (12-weeks) at 2 years were found to be less persistent to long-term follow-up. These eyes were found to have fewer active disease visits in the first 2 years (40%) than eyes treated at 4-weekly intervals (66%, p < 0.001). In the multivariable analysis, better vision at 2 years was associated with a lower risk of non-persistence (hazards ratio [HR] [95% CI]: 0.95 [0.93, 0.97], P < 0.001), while longer treatment intervals (HR [95% CI]: 1.31 [0.95, 1.8] and 1.54 [1.15, 2.06] for 12-week and > 12-week intervals vs. 4-week intervals, respectively, P = 0.002) and older patients (HR [95% CI]: 1.03 [1.02, 1.04], p < 0.001) were at higher risk of non-persistence. CONCLUSIONS: We found that patients on longer treatment intervals at 2 years were more likely to be non-persistent with treatment in later years. Reinforcing the need for ongoing treatment is important for patients on longer intervals who may feel complacent or that treatment is no longer effective, particularly if newer, longer lasting agents become widely available.

Hemiretinal vein occlusion 12-month outcomes are unique with vascular endothelial growth factor inhibitors: data from the Fight Retinal Blindness! Registry.

BACKGROUND/AIMS: To describe baseline characteristics and 12-month outcomes with vascular endothelial growth factor (VEGF) inhibitors of treatment-naïve hemiretinal vein occlusion (HRVO) compared with branch (BRVO) and central (CRVO) variants in routine clinical care. METHODS: A database observational study recruited 79 HRVO eyes, 590 BRVO eyes and 344 CRVO eyes that initiated therapy over 10 years. The primary outcome was mean change in visual acuity (VA-letters read on a logarithm of minimal angle of resolution chart) at 12 months. Secondary outcomes included mean change in central subfield thickness (CST), injections and visits. RESULTS: At baseline, mean VA in HRVO (53.8) was similar to CRVO (51.9; p=0.40) but lower than BRVO (59.4; p=0.009). HRVO eyes improved to match BRVO eyes from soon after treatment started through 12 months. Mean change in VA was greater in HRVO (+16.4) than both BRVO (+11.4; p=0.006) and CRVO (+8.5; p<0.001). Mean change in CST in HRVO (-231 µm) was similar to CRVO (-259 µm; p=0.33) but greater than BRVO eyes (-151 µm; p=0.003). The groups had similar median burdens of eight injections and nine visits. CONCLUSIONS: HRVO generally experienced the greatest mean change in VA of the three types of RVO when treated with VEGF inhibitors, ending with similar 12-month VA and CST to BRVO despite starting closer to CRVO. Inclusion of HRVO in BRVO or CRVO cohorts of clinical trials would be expected to proportionally inflate and skew the visual and anatomic outcomes.

Efficacy and safety of brolucizumab versus aflibercept in eyes with early persistent retinal fluid: 96-week outcomes from the HAWK and HARRIER studies.

OBJECTIVE: Post-hoc analysis to compare the outcomes of brolucizumab 6 mg vs. aflibercept 2 mg in neovascular age-related macular degeneration (nAMD) patients with early persistent retinal fluid in HAWK and HARRIER. METHODS: After 3 monthly loading doses, brolucizumab-treated eyes (N = 730) received injections every 12 weeks (q12w) or q8w if disease activity was detected. Aflibercept-treated eyes (N = 729) received fixed q8w dosing. Early persistent fluid was defined as the presence of subretinal fluid and/or intraretinal fluid up to Week 12. RESULTS: A lower proportion of brolucizumab patients had early persistent retinal fluid compared with aflibercept (11.2% (n = 82) vs. 19.2% (n = 140)). In these patients, 34.1% of the brolucizumab-treated group achieved a ≥ 15 ETDRS letter gain in best corrected visual acuity (BCVA) from baseline at Week 96 compared with 20.7% of the aflibercept-treated group. Brolucizumab achieved numerically better BCVA outcomes (Week 96: brolucizumab, +6.4 letters; aflibercept, +3.7 letters) and significantly greater central subfield thickness reductions versus aflibercept from baseline through Week 96 (Week 96: -202 µm vs. -145 µm; p = 0.0206). Brolucizumab demonstrated an overall favourable benefit/risk profile in this patient cohort. In their unmasked, post-hoc review, the Safety Review Committee identified two cases of retinal vasculitis and no cases of retinal vascular occlusion in the brolucizumab arm; no cases of retinal vasculitis or retinal vascular occlusion were identified in the aflibercept arm. CONCLUSION: In this analysis, anatomical and visual outcomes were better with brolucizumab compared with aflibercept. Brolucizumab may therefore achieve greater disease control than aflibercept in nAMD patients with early persistent retinal fluid.

Central Retinal Vein Occlusion 36-Month Outcomes with Anti-VEGF: The Fight Retinal Blindness! Registry.

PURPOSE: To analyze the 3-year outcomes in a broad population of patients starting VEGF inhibitors for central retinal vein occlusion (CRVO) in routine clinical practice. DESIGN: Observational database study. PARTICIPANTS: Overall, 527 treatment-naïve CRVO eyes that commenced VEGF inhibitors between December 1, 2010 and 2018 were tracked in the Fight Retinal Blindness! registry. METHODS: Longitudinal models were used to plot changes in visual acuity (VA) and central subfield thickness (CST). MAIN OUTCOME MEASURES: Mean change in VA from baseline to 36 months, injections, visits, completion, switching, and suspensions of therapy > 180 days at the final review. RESULTS: Overall (527 eyes) mean VA change (95% confidence interval [CI]) was + 10 (7, 12) letters, 37% had final VA ≥ 70 and 30% ≤ 35 letters, mean CST changed -306 µm. Completers (257/527, 49%) had mean 36-month changes in VA and CST of + 12 letters and -324 µm with a median of 18 injections at 26 visits. The adjusted mean VA change was similar to each VEGF inhibitor (mean, + 11.4 letters) despite a greater reduction in CST with aflibercept (-310 µm) versus ranibizumab (-258 µm) versus bevacizumab (-216 µm; P < 0.001). Eyes with baseline VA that was trial-eligible (19-73 letters; 356/527, 68%) gained 7 letters, very poor (< 19 letters; 129/527, 24%) gained 22 letters, or very good (> 73 letters; 42/527, 8%) lost 7 letters. Switching (160/527, 30%) was most often to aflibercept (79 eyes). By using suspensions and discontinuation reasons, we identified similar proportions had ceased therapy (154/527, 29%) and were still receiving it at 36 months (165/527, 31%). Only 62/527 eyes (12%) had resolution of macular edema without treatment for > 6 months. CONCLUSIONS: Patients with CRVO that commenced VEGF inhibitors in routine care for whom follow-up was available had VA improvements of around 12 letters at 3 years, but with > 50% lost to follow-up, the VA outcome for the entire group was likely worse. The choice of VEGF inhibitor influenced CST but not VA outcomes. We estimated that around half of the eyes were still receiving injections after 36 months.

The Living Kidney Donor Safety Study: Protocol of a Prospective Cohort Study.

Background: Living kidney donation is considered generally safe in healthy individuals; however, there is a need to better understand the long-term effects of donation on blood pressure and kidney function. Objectives: To determine the risk of hypertension in healthy, normotensive adults who donate a kidney compared with healthy, normotensive non-donors with similar indicators of baseline health. We will also compare the 2 groups on the rate of decline in kidney function, the risk of albuminuria, and changes in health-related quality of life. Design Participants and Setting: Prospective cohort study of 1042 living kidney donors recruited before surgery from 17 transplant centers (12 in Canada and 5 in Australia) between 2004 and 2014. Non-donor participants (n = 396) included relatives or friends of the donor, or donor candidates who were ineligible to donate due to blood group or cross-match incompatibility. Follow-up will continue until 2021, and the main analysis will be performed in 2022. The anticipated median (25th, 75th percentile, maximum) follow-up time after donation is 7 years (6, 8, 15). Measurements: Donors and non-donors completed the same schedule of measurements at baseline and follow-up (non-donors were assigned a simulated nephrectomy date). Annual measurements were obtained for blood pressure, estimated glomerular filtration rate (eGFR), albuminuria, patient-reported health-related quality of life, and general health. Outcomes: Incident hypertension (a systolic/diastolic blood pressure ≥ 140/90 mm Hg or receipt of anti-hypertensive medication) will be adjudicated by a physician blinded to the participant's donation status. We will assess the rate of change in eGFR starting from 12 months after the nephrectomy date and the proportion who develop an albumin-to-creatinine ratio ≥3 mg/mmol (≥30 mg/g) in follow-up. Health-related quality of life will be assessed using the 36-item RAND health survey and the Beck Anxiety and Depression inventories. Limitations: Donation-attributable hypertension may not manifest until decades after donation. Conclusion: This prospective cohort study will estimate the attributable risk of hypertension and other health outcomes after living kidney donation.

Contexte: Chez les personnes en bonne santé, faire don d'un rein est généralement considéré comme sûr. Il convient toutefois de mieux comprendre les effets à long terme de ce don sur la pression artérielle et la fonction rénale. Objectifs: Déterminer le risque d'hypertension chez les adultes sains et normotendus qui donnent un rein par rapport à des non-donneurs sains et normotendus ayant des indicateurs de santé de base similaires. Nous comparerons également le taux de réduction de la fonction rénale, le risque d'albuminurie et les changements dans la qualité de vie liée à la santé entre les deux groupes. Cadre type d'étude et participants: Étude de cohorte rétrospective menée sur 1 042 donneurs de rein vivants, recrutés avant la chirurgie dans 17 centres de transplantation (12 au Canada et 5 en Australie) entre 2004 et 2014. Le groupe des non-donneurs (n=396) était constitué de parents ou amis du donneur, ou de candidats donneurs non admissibles à faire un don en raison d'une incompatibilité de groupe sanguin ou lors du test de compatibilité croisée. Le suivi s'est poursuivi jusqu'en 2021 et l'analyse principale sera effectuée en 2022. Le temps de suivi médian prévu (25e percentile, 75e percentile, maximum) après le don est de 7 ans (6, 8, 15 ans). Mesures: Les donneurs et les non-donneurs ont complété le même calendrier de mesures à l'inclusion et pendant le suivi (une date simulée de néphrectomie a été attribuée aux non-donneurs). Des mesures annuelles de pression artérielle, de débit de filtration glomérulaire estimé (DFGe), d'albuminurie, de qualité de vie liée à la santé autodéclarée et de santé générale ont été obtenues. Issues principales: L'hypertension incidente (pression artérielle systolique/diastolique ≥ 140/90 mm Hg ou prise d'un médicament antihypertenseur) sera jugée par un médecin aveugle au statut de don du participant. Nous évaluerons le taux de variation du DFGe à partir de 12 mois après la date de la néphrectomie et la proportion de participants qui développeront un rapport albumine/créatinine ≥ 3 mg/mmol (≥ 30 mg/g) pendant le suivi. La qualité de vie liée à la santé sera évaluée à l'aide du questionnaire de santé RAND de 36 questions et de l'Inventaire d'anxiété et de dépression de Beck. Limites: L'hypertension attribuable au don pourrait ne pas se manifester avant des décennies après le don. Conclusion: Cette étude de cohorte prospective permettra d'estimer le risque d'hypertension attribuable au don et d'autres effets sur la santé du donneur après un don de rein.
