RESUMO
OBJECTIVES: To evaluate whether exposure to the United States discriminatory housing practice of redlining, which occurred in over 200 cities in the 1930s, is associated with modern-day, community-level incidence of firearm injury. BACKGROUND: Firearm violence is a public health epidemic within the United States. Federal policies are crucial in both shaping and reducing the risk of firearm violence; identifying policies that might have contributed to risks also offers potential solutions. We analyzed whether 1930s exposure to the discriminatory housing practices that occurred in over 200 US cities was associated with the modern-day, community-level incidence of firearm injury. METHODS: We performed a nationwide retrospective cohort study between 2014 and 2018. Urban Zip Code Tabulation Areas (ZCTAs) historically exposed to detrimental redlining (grades C and D) were matched to unexposed ZCTAs based on modern-day population-level demographic characteristics (ie, age, Gini index, median income, percentage Black population, and education level). Incidence of firearm injury was derived from the Gun Violence Archive and aggregated to ZCTA level counts. Our primary outcome was the incidence of firearm injury, modeled using zero-inflated negative binomial regression. RESULTS: When controlling for urban firearm risk factors, neighborhoods with detrimental redlining were associated with 2.6 additional firearm incidents annually compared with nonredlined areas with similar modern-day risk factors. Over our study period, this accounts for an additional 23,000 firearm injuries. CONCLUSIONS: Historic, discriminatory Federal policies continue to impact modern-day firearm violence. Policies aimed at reversing detrimental redlining may offer an economic means to reduce firearm violence.

PURPOSE: To evaluate geographic variation and characterize the relative contributions of patient characteristics, physician practice, and geographic region on variation in primary rhegmatogenous retinal detachment (RRD) management. DESIGN: Retrospective claims-based analysis. PARTICIPANTS: Commercially insured patients with incident RRD diagnosed between 2008 and 2016 (12 779 patients). METHODS: We determined whether patients underwent primary RRD repair within 60 days of diagnosis and identified repair type. We characterized physicians using physician identifier variables and characterized geography by Combined Statistical Areas or Core-Based Statistical Area. We used multilevel mixed effects logistic regression models to evaluate patient-, physician-, and geographic-level variation in whether patients underwent RRD repair and used multilevel mixed effects multinomial models to characterize variation in repair type. For each model, we evaluated patient fixed effects and physician random effects nested within geographic random effects. We estimated intraclass correlation coefficients and variance partition coefficients, respectively, to compare relative contributions of patient, physician, and geography to overall variation. MAIN OUTCOME MEASURES: Odds ratios for RRD repair and variation estimates for patient, physician, and geography. RESULTS: Most incident RRD patients received treatment within 60 days post-diagnosis. Pars plana vitrectomy was most common (49%), followed by laser barricade (23%), scleral buckle and pneumatic retinopexy (both 11%), and cryotherapy (5%). Physician-level variation showed greater impact on receipt of any treatment than geographic-level variation (estimated variance coefficients of 1.09 and 0.32, respectively). Patient-level characteristics represented approximately 82% of overall variation in receipt of any repair, versus 16% from physician-level and 2% from geographic-level factors. Among RRD patients who underwent repair, estimated variance coefficients were 0.07 for geography and 3.37 for physician. Physician-level factors represented approximately 50% of total variation in repair type, followed by patient-level (49%), and geographic-level (1%) factors. CONCLUSIONS: Rhegmatogenous retinal detachment repair decisions are influenced by patient-level and physician-level factors, less so by geographic variation. Patient characteristics account for most of the variation in receipt of repair, and physician practice accounts for most of the variation in choice of procedure. These findings indicate a need for additional studies to understand drivers behind differences in care and clinical outcomes and to identify barriers in access to care.

PURPOSE: To determine the association and cumulative dose-response pattern between pentosan polysulfate sodium (PPS) use for interstitial cystitis (IC) and maculopathy. DESIGN: Large, multicenter, retrospective cohort study of commercially insured patients in the MarketScan database (Truven Health Analytics, San Jose, CA). PARTICIPANTS: Two hundred twenty-seven thousand three hundred twenty-five patients with IC who were enrolled continuously in the MarketScan database. METHODS: Cox proportional hazards models (controlling for patient gender, age at index diagnosis of IC, and diagnosis with diabetes mellitus) followed up patients from index diagnosis of IC for 5 years, or until patients discontinued insurance coverage, or until patients' first diagnosis with a maculopathy. As a sensitivity analysis, we re-estimate all models after excluding all patients with diabetes. To assess for dose response, we calculated the total days of PPS prescriptions filled and created a categorical variable indicating total exposure. MAIN OUTCOME MEASURES: The primary outcome measure was association between binary PPS exposure and any maculopathy. Secondary outcome measures included exposure between binary and categorical, time-dependent, exposure to PPS and to drusen, nonexudative age-related macular degeneration (AMD), exudative AMD, hereditary maculopathy, and toxic maculopathy. RESULTS: The most common diagnoses of maculopathy in patients with IC were exudative AMD (1.5%), drusen (0.8%), nonexudative AMD (0.3%), toxic maculopathy (0.1%), and hereditary dystrophy (0.04%). In unadjusted analyses, the percentage of patients who filled a PPS prescription and were diagnosed later with a maculopathy (2.37%) was very similar to the percentage of patients who did not fill a prescription (2.77%). Survival models using a binary variable indicating PPS exposure showed no significant associations between PPS exposure and diagnosis of drusen, nonexudative AMD, exudative AMD, toxic maculopathy, hereditary dystrophy, or an aggregate variable of any maculopathy. Similarly, there was no dose-dependent relationship between PPS exposure and diagnosis of any maculopathy. These findings remained stable in sensitivity analysis models that excluded patients with diabetes mellitus. CONCLUSIONS: In this large, commercial claims database analysis, no association was found between PPS exposure and subsequent diagnosis of maculopathy.

BACKGROUND: The morbidity and mortality associated with opioid and benzodiazepine co-prescription is a pressing national concern. Little is known about patterns of opioid and benzodiazepine use in patients with acute low back pain or lower extremity pain. OBJECTIVE: To characterize patterns of opioid and benzodiazepine prescribing among opioid-naïve, newly diagnosed low back pain (LBP) or lower extremity pain (LEP) patients and to investigate the relationship between benzodiazepine prescribing and long-term opioid use. DESIGN/SETTING: We performed a retrospective analysis of a commercial database containing claims for more than 75 million enrollees in the USA. PARTICIPANTS: Participants were adult patients newly diagnosed with LBP or LEP between 2008 and 2015 who did not have a red flag diagnosis, had not received an opioid prescription in the 6 months prior to diagnosis, and had 12 months of continuous enrollment after diagnosis. MAIN OUTCOMES AND MEASURES: Among patients receiving at least one opioid prescription within 12 months of diagnosis, we defined discrete patterns of benzodiazepine prescribing-continued use, new use, stopped use, and never use. We tested the association of these prescription patterns with long-term opioid use, defined as six or more fills within 12 months. RESULTS: We identified 2,497,653 opioid-naïve patients with newly diagnosed LBP or LEP. Between 2008 and 2015, 31.9% and 11.5% of these patients received opioid and benzodiazepine prescriptions, respectively, within 12 months of diagnosis. Rates of opioid prescription decreased from 34.8% in 2008 to 27.0% in 2015 (P < 0.001); however, prescribing of benzodiazepines only decreased from 11.6% in 2008 to 10.8% in 2015. Patients with continued or new benzodiazepine use consistently used more opioids than patients who never used or stopped using benzodiazepines during the study period (one-way ANOVA, P < 0.001). For patients with continued and new benzodiazepine use, the odds ratio of long-term opioid use compared with those never prescribed a benzodiazepine was 2.99 (95% CI, 2.89-3.08) and 2.68 (95% CI, 2.62-2.75), respectively. LIMITATIONS: This study used administrative claims analyses, which rely on accuracy and completeness of diagnostic, procedural, and prescription codes. CONCLUSION: Overall opioid prescribing for low back pain or lower extremity pain decreased substantially during the study period, indicating a shift in management within the medical community. Rates of benzodiazepine prescribing, however, remained at approximately 11%. Concurrent prescriptions of benzodiazepines and opioids after LBP or LEP diagnosis were associated with increased risk of long-term opioid use.

BACKGROUND: Several online resources such as Google Trends (GT) enable plastic surgeons to track search volume trends for cosmetic procedures. Understanding these data may allow surgeons to better anticipate patients' interests and meet their needs. OBJECTIVES: The authors sought to evaluate the correlation between GT search volumes and annual surgery volumes. METHODS: Search terms were generated using the "related queries" feature of GT. Data were obtained for the terms breast augmentation, buttock augmentation, buttock implants, buttock lift, calf augmentation, liposuction, lower body lift, thighplasty, abdominoplasty, and brachioplasty from January 2004 to November 2017. Annual volumes for respective procedures were obtained from statistics reports of the American Society of Plastic Surgeons (ASPS) from 2006 to 2017 and American Society of Aesthetic Plastic Surgery (ASAPS) from 2004 to 2017. Correlations were evaluated applying univariate linear regression of GT data to both ASPS and ASAPS data. RESULTS: Geographical and temporal variations in search volume were detected during the study. Search volume trends that correlated significantly with both ASPS and ASAPS surgery volume trends were: "butt implants surgery" (ASPS: R2 = 0.366, P = 0.049; ASAPS: R2 = 0.380, P = 0.019); "liposuction" (ASPS: R2 = 0.690, P = 0.002; ASAPS: R2 = 0.578, P = 0.002); and "liposuction surgery" (ASPS: R2 = 0.672, P = 0.002; ASAPS: R2 = 0.476, P = 0.006). Several search terms demonstrated no significant relationships, negative correlations, or were significant with only one database. CONCLUSIONS: This study characterizes GT as a convenient and informative data set for plastic surgeons to analyze patient interest in cosmetic body-sculpting procedures. GT represents a useful instrument for tailoring marketing strategies and addressing the needs of our patient population.

BACKGROUND: Google Trends (GT) is a free, open-source tool that permits customizable analysis of search term volumes entered into the Google search engine. Google Trends data may offer useful and actionable insight to plastic surgeons pertaining to worldwide, national, and regional evolution of patient interest for breast procedures and other common surgeries. METHODS: Search terms were generated using the "related queries" feature of GT. Google Trends data were collected for breast lift, breast reduction, breast reconstruction, and male breast reduction from January 2004 to September 2017. Case volumes for respective procedures were obtained from the American Society of Plastic Surgeons (ASPS) annual statistics reports for the calendar year 2006 to 2016. Trend analysis was performed using univariate linear regression analysis of ASPS statistics and GT search data. RESULTS: Total search volume varied geographically and temporally during the study period. Statistically significant positive correlations between GT and ASPS data were as follows: breast lift: "mastopexy" (R = 0.445, P = 0.025); male breast reduction: "gynecomastia surgery" (R = 0.45, P = 0.024); and breast reconstruction: "tissue expander" (R = 0.806, P ≤ 0.001) and "TRAM flap reconstruction" (R = 0.764, P = 0.002). For several search terms, no significant correlation was detected, highlighting the importance for careful selection of terms.

BACKGROUND: The utility of Google Trends (GT) in analyzing worldwide and regional patient interest for plastic surgery procedures is becoming invaluable to plastic surgery practices. GT data may offer practical information to plastic surgeons pertaining to seasonal and geographic trends in interest in facial cosmetic procedures. OBJECTIVES: The authors sought to analyze geographic and temporal trends between GT search volumes and US surgery volumes using univariate analysis. METHODS: The "related queries" feature of GT generated potential search terms. GT data were compiled for cheek implants, mentoplasty, otoplasty, blepharoplasty, rhytidectomy, forehead lift, hair transplantation, lip augmentation, lip reduction, platysmaplasty, and rhinoplasty from January 2004 to December 2017. Annual volumes for respective procedures were obtained from annual statistics reports of the American Society of Plastic Surgeons (ASPS) from 2006 to 2017 and American Society of Aesthetic Plastic Surgery (ASAPS) from 2004 to 2017. RESULTS: Geographical and temporal variations in search volume were detected during the study. Search volume trends that correlated significantly with both ASPS and ASAPS surgery volume trends were: "eyelid plastic surgery" (ASPS R2 = 0.336, P = 0.048; ASAPS R2 = 0.661, P = 0.001); "facelift" (ASPS R2 = 0.767, P ≤ 0.001; ASAPS R2 = 0.767, P = 0.001); "lip injections" (ASPS R2 = 0.539, P = 0.007; ASAPS R2 = 0.461, P = 0.044); and "rhinoplasty surgery" (ASPS R2 = 0.797, P ≤ 0.001; ASAPS R2 = 0.441, P = 0.01). Several search terms demonstrated no significant relationships or were significant with only one database. CONCLUSIONS: GT may provide a high utility for informing plastic surgeons about the interest expressed by our patient population regarding certain cosmetic search terms and procedures. GT may represent a convenient tool for optimizing marketing and advertising decisions.

OBJECTIVE Preoperative depression has been linked to a variety of adverse outcomes following lumbar fusion, including increased pain, disability, and 30-day readmission rates. The goal of the present study was to determine whether preoperative depression is associated with increased narcotic use following lumbar fusion. Moreover, the authors examined the association between preoperative depression and a variety of secondary quality indicator and economic outcomes, including complications, 30-day readmissions, revision surgeries, likelihood of discharge home, and 1- and 2-year costs. METHODS A retrospective analysis was conducted using a national longitudinal administrative database (MarketScan) containing diagnostic and reimbursement data on patients with a variety of private insurance providers and Medicare for the period from 2007 to 2014. Multivariable logistic and negative binomial regressions were performed to assess the relationship between preoperative depression and the primary postoperative opioid use outcomes while controlling for demographic, comorbidity, and preoperative prescription drug-use variables. Logistic and log-linear regressions were also used to evaluate the association between depression and the secondary outcomes of complications, 30-day readmissions, revisions, likelihood of discharge home, and 1- and 2-year costs. RESULTS The authors identified 60,597 patients who had undergone lumbar fusion and met the study inclusion criteria, 4985 of whom also had a preoperative diagnosis of depression and 21,905 of whom had a diagnosis of spondylolisthesis at the time of surgery. A preoperative depression diagnosis was associated with increased cumulative opioid use (ß = 0.25, p < 0.001), an increased risk of chronic use (OR 1.28, 95% CI 1.17-1.40), and a decreased probability of opioid cessation (OR 0.96, 95% CI 0.95-0.98) following lumbar fusion. In terms of secondary outcomes, preoperative depression was also associated with a slightly increased risk of complications (OR 1.14, 95% CI 1.03-1.25), revision fusions (OR 1.15, 95% CI 1.05-1.26), and 30-day readmissions (OR 1.19, 95% CI 1.04-1.36), although it was not significantly associated with the probability of discharge to home (OR 0.92, 95% CI 0.84-1.01). Preoperative depression also resulted in increased costs at 1 (ß = 0.06, p < 0.001) and 2 (ß = 0.09, p < 0.001) years postoperatively. CONCLUSIONS Although these findings must be interpreted in the context of the limitations inherent to retrospective studies utilizing administrative data, they provide additional evidence for the link between a preoperative diagnosis of depression and adverse outcomes, particularly increased opioid use, following lumbar fusion.

OBJECTIVE: To determine the effective coverage of obstetric care in a rural Tanzanian region and to assess differences in effective coverage by wealth. DESIGN: Cross-sectional structured interviews. SETTING: Pwani Region, Tanzania. PARTICIPANTS: The study includes 24 rural, government-managed, primary healthcare clinics and their catchment populations. From January-April 2016, we conducted a household survey of a census of women with recent deliveries, health worker knowledge surveys and facility audits. MAIN OUTCOME MEASURES: We explored the proportion of women receiving quality care through the cascade and conducted an equity analysis by wealth. RESULTS: In total, 2,910 of 3,564 women (81.6%) reported delivering their most recent child in a health facility, 1,096 of whom delivered in a study facility. Using a minimum threshold of quality, the effective coverage of obstetric care was 25%. Quality was lowest in the emergency care dimensions, with the average score on the provider knowledge tests at 47% and the average provision of basic emergency obstetric services below 50%. The wealthiest 20% of women were 4.1 times as likely to deliver in facilities offering at least the minimum threshold of quality care through the cascade compared to the poorest 80% of women (95% confidence interval: 1.5-11.3). CONCLUSIONS: Effective coverage of delivery care is very low, particularly among poorer women. Health worker knowledge caused the sharpest decline in effective coverage. Measures of effective coverage are a better performance measure of under-resourced health systems than utilization. Equity analyses can further identify important discrepancies in quality across socio-economic levels. TRIAL REGISTRATION: ISRCTN 17107760.

OBJECTIVES: To examine factors associated with home delivery among women in Pwani Region, Tanzania, which has experienced a rapid rise in facility delivery coverage. METHODS: Cross-sectional data from a population-based survey of women residing in rural areas of Pwani Region were linked to health facility locations. We fitted multilevel logistic models to examine individual and community factors associated with home delivery. RESULTS: A total of 752 (27.95%) of the 2691 women who completed the survey delivered their last child at home. Women were less likely to deliver at home if they had any primary education [odds ratio (OR) 0.62; 95% confidence interval (CI): 0.50, 0.79], were primiparous (OR: 0.52; 95% CI: 0.37, 0.73), had more exposure to media (OR: 0.80; 95% CI: 0.66, 0.96) or had received more (OR: 0.78; 95% CI: 0.63, 0.96) or better quality antenatal care (ANC) services (OR: 0.48; 95% CI: 0.34, 0.67). Increased wealth was strongly associated with lower odds of home delivery (OR: 0.27; 95% CI: 0.18, 0.39), as was living in a village that grew cash crops (OR: 0.56; 95% CI: 0.35, 0.88). Farther distance to hospital, but not to lower level facilities, was associated with higher likelihood of home delivery (OR 2.49; 95% CI: 1.60, 3.88). CONCLUSIONS: Poverty, multiparity, weak ANC and distance to hospital were associated with persistence of home delivery in a region with high coverage of facility delivery. A pro-poor path to universal coverage of safe delivery requires a greater focus on quality of care and more intensive outreach to poor and multiparous women.

AIM: To evaluate the efficacy of pneumatic retinopexy (PR) in patients undergoing PR as primary treatment for rhegmatogenous retinal detachment (RRD) and analyze the factors associated with success and failure in the studied population. METHODS: A retrospective chart review was done of patients with RRD treated with PR as primary management method treated at New York Eye and Ear Infirmary of Mount Sinai between January 2017 and December 2021. Primary outcome measured success or failure of PR. Secondary outcome measured best corrected visual acuity (BCVA) after PR. A separate risk analysis was done to identify and stratify risks associated with success and failure of PR. RESULTS: A total of 179 eyes from 179 patients were included for final analysis. The 83 patients (46.37%) achieved anatomical reattachment of the retina after primary PR with no need for additional surgery. The 96 patients (53.63%) had a failed primary PR and required a PPV and 6 of them required pars plana vitrectomy (PPV) with scleral buckle (SB). In total, 19 cases (10.61%) were done as temporizing pneumatics, 18 (94.74%) underwent PPV, and 1 (5.26%) did not require further intervention. The visual acuities at postoperative month 1 (POM1) for patients who underwent primary PR successfully and for those that underwent PPV after, were 0.58 (20/80) and 1.03 (20/200) respectively. Patients who met Pneumatic Retinopexy Versus Vitrectomy for the Management of Primary Rhegmatogenous Retinal Detachment Outcomes Randomized Trial (PIVOT) criteria had a statistically significant decreased risk of primary PR failing (hazard ratio 0.29, P=0.00). Majority of missed or new breaks were found superotemporally. CONCLUSION: PR is a good treatment option for treating RRDs in patients that meet PIVOT criteria and can be conducted as a temporizing measure. PIVOT criteria and fovea on status decrease the risk of PR failure.
RESUMO
Although the impact of the SARS-CoV-2 pandemic on major metropolitan areas is broadly reported and readily available, regions with lower populations and more remote areas in the United States are understudied. The objective of this study is to determine the progression of SARS-CoV-2 sequence variants in a frontier and remote intermountain west state among university-associated communities. This study was conducted at two intermountain west universities from 2020 to 2022. Positive SARS-CoV-2 samples were confirmed by quantitative real-time reverse transcription-polymerase chain reaction and variants were identified by the next-generation sequencing of viral genomes. Positive results were obtained for 5355 samples, representing a positivity rate of 3.5% overall. The median age was 22 years. Viral genomic sequence data were analyzed for 1717 samples and phylogeny was presented. Associations between viral variants, age, sex, and reported symptoms among 1522 samples indicated a significant association between age and the Delta variant (B 1.167.2), consistent with the findings for other regions. An outbreak event of AY122 was detected August-October 2021. A 2-month delay was observed with respect to the timing of the first documented viral infection within this region compared to major metropolitan regions of the US.

PURPOSE: To characterize delays in diagnosis and treatment of retinal detachments (RDs) in a pediatric population. DESIGN: Retrospective cohort study using insurance claims data. SUBJECTS: Pediatric patients with RD who underwent repair in the outpatient setting. METHODS: A retrospective analysis of commercially insured patients from a national cohort (IBM MarketScan Research Databases) aged ≤ 18 years with an incident diagnosis of RD between 2007 and 2016. Patients with preceding eye-related visits, time to diagnosis, and time to repair were calculated and compared between patients with pre-existing ocular diagnosis and those without. MAIN OUTCOME MEASURES: The time from diagnosis to specialist consultation, time from diagnosis to repair, time from specialist consultation to repair, number of preceding visits, and presence of previous eye-related diagnosis. RESULTS: Our sample consisted of 826 patients, the majority (77%) of whom were diagnosed with rhegmatogenous RD. Only 40% of patients had at least 1 preceding eye-related visit, and 33% had at least 2 visits before RD diagnosis, with a median time from the last eye-related visit of 32 days (4-197 days) and median time from the second to last visit of 118 days (24-437 days). The median time from RD diagnosis to repair was 2 days (0-9 days). The 323 (37.9%) patients with pre-existing ocular diagnoses more frequently had at least 1 (44% vs. 37%; P = 0.079) or 2 preceding eye-related visits (40% vs. 29%; P = 0.002) compared with those without and also had a shorter time to RD diagnosis (median, 14.5 days vs. 44.5 days; P = 0.011) and repair (1 day vs. 3 days; P = 0.003). CONCLUSIONS: Retinal detachment is an important cause of morbidity in children. This work highlighted how pediatric patients without previous ocular diagnoses and visits with eye care professional may have a delayed diagnosis and repair of their RD.

BACKGROUND: In private equity (PE) buyouts of medical practices, it is common for the PE firm to raise significant levels of debt in order to finance the purchase. This debt is subsequently shouldered by the acquired practice(s). There remains a scarcity of literature quantifying the effect of PE acquisition on the subsequent financial performance of eye care practices. We aim to identify and characterize debt valuations of ophthalmology and optometry private equity-backed group (OPEG) practices, which serve as an indicator of practice financial performance. METHODS: A cross-sectional study from March 2017 to March 2022 was conducted using business development company (BDC) quarterly/annual filings to the Securities and Exchange Commission (SEC). The 2021 BDC Report was used to identify all BDCs actively filing annual reports (Form 10-Ks) and quarterly reports (Form 10-Qs) in the United States in 2021. The public filings of BDCs lending to OPEGs were searched from the inception of the OPEG's debt instrument in a BDC's portfolio and the amortized cost and fair value of each debt instrument were tabulated. A panel linear regression was used to evaluate temporal changes in OPEG valuations. RESULTS: A total of 2,997 practice locations affiliated with 14 unique OPEGs and 17 BDCs were identified over the study period. Debt valuations of OPEGs decreased by 0.46% per quarter over the study period (95% CI: -0.88 to -0.03, P = 0.036). In the COVID-19 pre-vaccine period (March 2020 to December 2020), there was an excess (additional) 4.93% decrease in debt valuations (95% CI: -8.63 to -1.24, P = 0.010) when compared to pre-pandemic debt valuations (March 2017 to December 2019). Effects of COVID-19 on valuations stabilized during the pandemic post-vaccine period (February 2021 to March 2022), with no change in excess debt valuation compared to pre-pandemic baseline (0.60, 95% CI: -4.59 to 5.78, P = 0.822). There was an increase in practices that reported average discounted debt valuations from 20 practices (1.6%) associated with one OPEG to 1,213 practices (40.5%) associated with nine OPEGs (including 100% of newly acquired practices), despite the stabilization of COVID-19-related excess (additional) debt. CONCLUSIONS: Debt valuations of eye care practices have declined significantly post-PE investment from March 2017 to March 2022, suggesting that the financial health of these groups is volatile and vulnerable to economic contractions such as the COVID-19 pandemic. Eye care practice owners must consider long-term financial risks and impacts of subsequent patient care when selling their practice to a private equity group. Future research should assess the impact of secondary transactions of OPEGs on the financial health of practices, practitioner lifestyle, and patient outcomes.
RESUMO
OBJECTIVE: Vision changes can precipitate falls in the elderly resulting in significant morbidity and mortality. We hypothesized that pseudophakic monovision and ensuing anisometropia and aniseikonia impact elderly fall risk. This study assessed fall risk in patients with pseudophakic monovision, pseudophakic single vision distance (classic cataract surgery), and cataracts with no surgery. DESIGN: Retrospective single-institution cohort study PARTICIPANTS: Patients with bilateral cataracts diagnosed at 60 years of age or older who underwent bilateral cataract surgery (monovision or single vision distance) or did not undergo any cataract surgery (n = 13 385). Patients with unilateral surgery or a fall prior to cataract diagnosis were excluded. METHODS: Data were obtained from the Stanford Research Repository. Time-to-fall analysis was performed across all 3 groups. Primary outcome was hazard ratio (HR) for fall after second eye cataract surgery or after bilateral cataract diagnosis. RESULTS: Of 13 385 patients (241 pseudophakic monovision, 2809 pseudophakic single vision, 10 335 no surgery), 850 fell after cataract diagnosis. Pseudophakic monovision was not associated with fall risk after controlling for age, sex, and myopia. Pseudophakic single-vision patients had a decreased time to fall compared with no-surgery patients (log rank, p < 0.001). Older age at cataract diagnosis (HR =1.05, 95% confidence interval [CI] 1.04-1.06, p < 0.001) or at time of surgery (HR = 1.05, 95% CI 1.03-1.07, p < 0.001) increased fall risk, as did female sex (HR = 1.29, 95% CI 1.10-1.51, p = 0.002) and preexisting myopia (HR = 1.31, 95% CI 1.01-1.71, p = 0.046) among nonsurgical patients. CONCLUSIONS: Pseudophakic monovision did not impact fall risk, but pseudophakic single vision may increase falls compared with patients without cataract surgery.

Importance: Firearm injuries are an epidemic in the US; more than 45â¯000 fatal injuries were recorded in 2020 alone. Gaining a deeper understanding of socioeconomic factors that may contribute to increasing firearm injury rates is critical to prevent future injuries. Objective: To explore whether neighborhood gentrification is associated with firearm injury incidence rates over time. Design, Setting, and Participants: This cross-sectional study used nationwide, urban US Census tract-level data on gentrification between 2010 and 2019 and firearm injuries data collected between 2014 and 2019. All urban Census tracts, as defined by Rural Urban Commuting Area codes 1 to 3, were included in the analysis, for a total of 59â¯379 tracts examined from 2014 through 2019. Data were analyzed from January 2022 through April 2023. Exposure: Gentrification, defined to be an area in a central city neighborhood with median housing prices appreciating over the median regional value and a median household income at or below the 40th percentile of the median regional household income and continuing for at least 2 consecutive years. Main Outcomes and Measures: The number of firearm injuries, controlling for Census tract population characteristics. Results: A total of 59 379 urban Census tracts were evaluated for gentrification; of these tracts, 14 125 (23.8%) were identified as gentrifying, involving approximately 57 million residents annually. The firearm injury incidence rate for gentrifying neighborhoods was 62% higher than the incidence rate in nongentrifying neighborhoods with similar sociodemographic characteristics (incidence rate ratio [IRR], 1.62; 95% CI, 1.56-1.69). In a multivariable analysis, firearm injury incidence rates increased by 57% per year for low-income Census tracts that did not gentrify (IRR, 1.57; 95% CI, 1.56-1.58), 42% per year for high-income tracts that did not gentrify (IRR, 1.42; 95% CI, 1.41-1.43), and 49% per year for gentrifying tracts (IRR, 1.49; 95% CI, 1.48-1.50). Neighborhoods undergoing the gentrification process experienced an additional 26% increase in firearm injury incidence above baseline increase experienced in neighborhoods not undergoing gentrification (IRR, 1.26; 95% CI, 1.23-1.30). Conclusions and Relevance: Results of this study suggest that gentrification is associated with an increase in the incidence of firearm injuries within gentrifying neighborhoods. Social disruption and residential displacement associated with gentrification may help explain this finding, although future research is needed to evaluate the underlying mechanisms. These findings support use of targeted firearm prevention interventions in communities experiencing gentrification.

Myopia is a known risk factor for rhegmatogenous retinal detachment (RRD). Given global trends of increasing myopia, we aimed to determine the absolute risk (incidence rate) of RRD in non-myopes, myopes and high myopes in the United States over ten years. We performed a retrospective cohort study of 85,476,781 commercially insured patients enrolled in the Merative™ Marketscan® Research Database. The incidence rate of RRD in phakic patients in the United States was 39-fold higher in high myopes than non-myopes (868.83 per 100,000 person-years versus 22.44 per 100,000 person-years) and three-fold higher in myopes than non-myopes (67.51 per 100,000 person-years versus 22.44 per 100,000 person-years). The incidence rate was significantly higher in males in each category (P < 0.01). Combined, the incidence rate of RRD in phakic patients in the United States from 2007 to 2016 was 25.27 RRDs per 100,000 person-years, a rate higher than those in prior published studies in North America, South America, Europe, Asia, and Australia. The absolute risk of myopia and high myopia increased from 2007 to 2016. The risk of RRD in phakic high myopes rose with increasing age. Notably, the magnitude of increased risk of RRD in myopes varied substantially according to the minimum follow-up period in our models and should be accounted for when interpreting data analyses.
