RESUMEN
OBJECTIVE: To assess whether the relationship between hearing and depressive symptoms is present among older adults classified as normal hearing (≤25 dB). DESIGN: Cross-sectional epidemiologic study (Hispanic Community Health Study). SETTING: US multicentered. PARTICIPANTS: Adults ≥50 years old (nâ¯=â¯5,499) with normal hearing or hearing loss (HL). MEASUREMENTS: The primary exposure was hearing, defined continuously by the 4-frequency pure-tone average threshold (dB) on audiometry. Hearing was additionally categorized into normal hearing (≤25 dB) and HL (>25 dB). The main outcome was depressive symptoms, measured with the Center for Epidemiologic Studies Depression Scale-10 (CESD-10). Depressive symptoms were defined both continuously and binarily (where CESD-10 ≥10 was categorized as clinically significant depressive symptoms). Multivariable linear, logistic, and generalized additive modeling (GAM) regressions were performed. RESULTS: Among those with normal hearing, the CESD-10 score increased by 1.04 points (95% confidence interval [CI]: 0.70, 1.37) for every 10 dB decrease in hearing, adjusting for age, gender, education, cardiovascular disease, and hearing aid use. Among those with HL, the CESD-10 score increased by 0.62 points (95% CI: 0.23, 1.01) for every 10 dB decrease in hearing, adjusting for the same confounders. Similar findings were noted when the outcome was clinically significant depressive symptoms (adjusted odds ratio: 1.28 [1.14, 1.44] in normal hearing versus 1.26 [1.11, 1.44] in HL). In certain sensitivity analyses, the relationship between hearing and depressive symptoms was significantly stronger among those with normal hearing than in those with HL. CONCLUSION: The relationship between hearing and clinically significant depressive symptoms is present among older adults with normal hearing (<25 dB). We introduce the term subclinical HL as imperfect hearing that is classically defined as normal (1-25 dB). The relationship between hearing and late life depressive symptoms may be more sensitive than previously recognized.

BACKGROUND: The authors developed a practical and clinically useful model to predict the risk of psychosis that utilizes clinical characteristics empirically demonstrated to be strong predictors of conversion to psychosis in clinical high-risk (CHR) individuals. The model is based upon the Structured Interview for Psychosis Risk Syndromes (SIPS) and accompanying clinical interview, and yields scores indicating one's risk of conversion. METHODS: Baseline data, including demographic and clinical characteristics measured by the SIPS, were obtained on 199 CHR individuals seeking evaluation in the early detection and intervention for mental disorders program at the New York State Psychiatric Institute at Columbia University Medical Center. Each patient was followed for up to 2 years or until they developed a syndromal DSM-4 disorder. A LASSO logistic fitting procedure was used to construct a model for conversion specifically to a psychotic disorder. RESULTS: At 2 years, 64 patients (32.2%) converted to a psychotic disorder. The top five variables with relatively large standardized effect sizes included SIPS subscales of visual perceptual abnormalities, dysphoric mood, unusual thought content, disorganized communication, and violent ideation. The concordance index (c-index) was 0.73, indicating a moderately strong ability to discriminate between converters and non-converters. CONCLUSIONS: The prediction model performed well in classifying converters and non-converters and revealed SIPS measures that are relatively strong predictors of conversion, comparable with the risk calculator published by NAPLS (c-index = 0.71), but requiring only a structured clinical interview. Future work will seek to externally validate the model and enhance its performance with the incorporation of relevant biomarkers.

BACKGROUND: Hypoplastic left heart syndrome is the most expensive birth defect managed in the United States, with a 5-year survival rate below 70%. Increasing evidence suggests that hospital volumes are inversely associated with mortality for infants with single ventricles undergoing stage 1 surgical palliation. Our aim was to examine the relative effects of surgeon and institutional volumes on outcomes and resource utilisation for these children. METHODS: A retrospective study was conducted using the Pediatric Health Information System database to examine the effects of the number of procedures performed per surgeon and per centre on mortality, costs, and post-operative length of stay for infants undergoing Risk Adjustment for Congenital Heart Surgery risk category six operations at tertiary-care paediatric hospitals, from 1 January, 2004 to 31 December, 2013. Multivariable modelling was used, adjusting for patient and institutional characteristics. Gaussian kernel densities were constructed to show the relative distributions of the effects of individual institutions and surgeons, before and after adjusting for the number of cases performed. RESULTS: A total of 2880 infants from 35 institutions met the inclusion criteria. Mortality was 15.0%. Median post-operative length of stay was 24 days (IQR 14-41). Median standardized inpatient hospital costs were $156,000 (IQR $108,000-$248,000) in 2013 dollars. In the multivariable analyses, higher institutional volume was inversely associated with mortality (p=0.001), post-operative length of stay (p=0.004), and costs (p=0.001). Surgeon volume was associated with none of the measured outcomes. Neither institutional nor surgeon volumes explained much of the wide variation in outcomes and resource utilization observed between institutions and between surgeons. CONCLUSIONS: Increased institutional - but not surgeon - volumes are associated with reduced mortality, post-operative length of stay, and costs for infants undergoing stage 1 palliation.

OBJECTIVE: To compare the educational value of endoscopic ear surgery versus microscopic ear surgery among medical students. METHODS: Medical students anonymously completed a cross-sectional survey immediately after observing endoscopic or microscopic ear surgery. A Likert scale (1 = worst, 5 = best) was used to analyze variables across 3 domains including: (1) area of interest visibility, (2) optical quality, (3) education and understanding. The Mann-Whitney U-test and multivariable linear regression were used to compare mean scores of individual items and domain means between endoscopic and microscopic groups. RESULTS: Forty-four surveys were analyzed (20 endoscopic and 24 microscopic ear surgeries). Across domains, the endoscope was superior to the microscope (adjusted P < .05) for visibility of the area of interest (mean ± SD: 4.74 ± 0.26 vs 4.28 ± 0.50), optical quality (4.78 ± 0.38 vs 4.28 ± 0.64), and education and understanding (4.70 ± 0.47 vs 4.13 ± 0.61). In multivariable linear regression, the mean domain score for visibility of the area of interest was 1.23 (95% CI = 0.56, 1.90; adjusted P < .01) points higher for the endoscopic group, compared to the microscopic group, adjusting for surgeon, procedure, and student type. The mean domain score for education and understanding was 1.19 (95% CI = 0.49. 1.90; adjusted P < 0.01) points higher for the endoscopic group, compared to the microscopic group, adjusting for the same confounders. CONCLUSIONS: Among medical students, endoscopic ear surgery was superior to microscopic ear surgery for several visual quality indicators and perceived educational benefit. These findings have implications for medical student education and surgical training.
RESUMEN
BACKGROUND: Age-related hearing loss (HL), a common and treatable condition, has been associated with other age-related conditions. Late life cognitive impairment is a major public health concern that is rarely treatable. Studies examining the relationship between HL and cognition have been limited by non-Hispanic cohorts, small samples, or limited confounding control. We overcome these limitations in a large Hispanic cohort. METHODS: This was a multisite cross-sectional study of 5,277 subjects at least 50 years old (Hispanic Community Health Study, HCHS). The main exposure was audiometric HL. The main outcome measure was neurocognitive performance ascertained by the Digit Symbol Substitution Test (DSST), Word Frequency Test, Spanish-English Verbal Learning Test (SEVLT), and Six-Item Screener. RESULTS: The mean age was 58.4 years (SD = 6.2). A 20-dB (equivalent to a one-category worsening) increase in HL was associated with a -1.53 (95% CI, -2.11, -0.94) raw score point difference in the DSST, adjusting for demographics, hearing aid use, and cardiovascular disease. Similarly, a 20-dB increase in HL was associated with a -0.86 (-1.23, -0.49) point difference on the Word Frequency Test, -0.76 (-1.04, -0.47) on the SEVLT 3 trials, -0.45 (-0.60, -0.29) on the SELVT recall, and -0.07 (-0.12, -0.02) on the Six-Item Screener. CONCLUSIONS: In the largest study of formal, audiometric HL and cognition to date, HL was independently associated with worse performance in a range of neurocognitive measures. Because HL is common and potentially treatable, it should be investigated as a modifiable risk factor for neurocognitive decline and dementia.

Importance: Age-related hearing loss (HL) is a common and treatable condition that has been associated with cognitive impairment. The level of hearing at which this association begins has not been studied to date. Objective: To investigate whether the association between hearing and cognition is present among individuals traditionally classified as having normal hearing. Design, Setting, and Participants: Cross-sectional study of 2 US epidemiologic studies (Hispanic Community Health Study [HCHS], 2008-2011, and National Health and Nutrition Examination Study [NHANES], 1999-2000, 2001-2002, and 2011-2012 cycles). The dates of analysis were November 2018 to August 2019. Multivariable generalized additive model (GAM) regression and linear regression were used to assess the association between HL (exposure) and cognition (outcome). Participants included 6451 individuals aged 50 years or older from the general Hispanic population (HCHS [n = 5190]) and the general civilian, noninstitutionalized US population (NHANES [n = 1261]). Exposures: Audiometric HL (4-frequency pure-tone average). Main Outcomes and Measures: Neurocognitive performance measured by the Digit Symbol Substitution Test (DSST) (score range, 0-113), Word Frequency Test (range, 0-49), Spanish-English Verbal Learning Test (SEVLT) 3 trials (range, 5-40), SEVLT recall (range, 0-15), and Six-Item Screener (range, 0-6); higher scores indicated better cognitive performance. Results: Among 6451 individuals, the mean (SD) age was 59.4 (6.1) years, and 3841 (59.5%) were women. The GAM regression showed a significant inverse association between hearing and cognition across the entire spectrum of hearing after adjusting for demographics and cardiovascular disease. In separate multivariable linear regressions stratified by the classic binary definition of HL, decreased hearing was independently associated with decreased cognition in adults with normal hearing (pure-tone average ≤25 dB) across all cognitive tests in the HCHS. For example in this group, a 10-dB decrease in hearing was associated with a clinically meaningful 1.97-point (95% CI, 1.18-2.75) decrease in score on the DSST. When using a stricter HL cut point (15 dB), an association was also present in NHANES. The associations between hearing and cognition were stronger or equivalent in individuals with normal hearing than among those with HL. For example, there was a 2.28-point (95% CI, 1.56-3.00) combined cohort DSST score decrease per 10-dB decrease among individuals with normal hearing vs a 0.97-point (95% CI, 0.20-1.75) decrease among those with HL, with a significant interaction term between continuous and binary hearing. Conclusions and Relevance: An independent association was observed between cognition and subclinical HL. The association between hearing and cognition may be present earlier in HL than previously understood. Studies investigating whether treating HL can prevent impaired cognition and dementia should consider a lower threshold for defining HL than the current 25-dB threshold.

Importance: Age-related hearing loss is highly prevalent and has recently been associated with numerous morbid conditions of aging. Late-life depression is also prevalent and can be resistant to available treatments. Preliminary studies examining the association between hearing loss and late-life depression have been limited by subjective hearing measures, small sample sizes, and primarily white populations. Objective: To assess whether a cross-sectional association exists between objective audiometric hearing loss and depressive symptoms in older Hispanic adults. Design, Setting, and Participants: This cross-sectional study uses 2008-2011 Hispanic Community Health Study/Study of Latinos data collected in Miami, Florida, San Diego, California, Chicago, Illinois, or the Bronx, New York, from 5328 Hispanic adults 50 years or older who had exposure, outcome, and covariate data. Data analyses were conducted from March 2018 to September 2018. Exposure: Audiometric hearing loss (pure-tone average). Main Outcomes and Measures: Center for Epidemiologic Studies Depression Scale, 10-item version (CESD-10) score of 10 or higher, which indicates clinically significant depressive symptoms. Results: The median age (interquartile range) of the 5328 participants was 58 (53-63) years, and 3283 participants (61.6%) were female. The mean (SD) CESD-10 score was 7.7 (6.4). Of the 5328 included participants, 1751 (32.9%) had clinically significant depressive symptoms. The odds of having these symptoms increased 1.44 (95% CI, 1.27-1.63) times for every 20 dB of hearing loss, adjusting for hearing aid use, age, sex, educational level, study site, geographic background, cardiovascular disease, and antidepressant use. Compared with those for individuals with normal hearing (0 dB), the odds of having clinically significant depressive symptoms was 1.81 (95% CI, 1.48-2.22) times as high in individuals with mild hearing loss (median threshold, 32.5 dB), 2.38 (95% CI, 1.77-3.20) times as high in individuals with moderate hearing loss (median threshold, 47.5 dB), and 4.30 (95% CI, 2.61-7.09) times as high in individuals with severe hearing loss (median threshold, 80 dB). Conclusions and Relevance: Objective hearing loss appears to be associated with clinically significant depressive symptoms in older Hispanic people, with greater hearing loss seemingly associated with greater odds of having depressive symptoms. Given the high prevalence of untreated hearing loss in older adults, hearing loss may be a potentially modifiable risk factor for late-life depression.

OBJECTIVES: Our aim was to examine the effects of surgical timing on major morbidity, mortality, and total hospital reimbursement for late preterm and term infants with hypoplastic left heart syndrome (HLHS) undergoing stage 1 palliation within the first 2 weeks of life. METHODS: We conducted a retrospective cohort study of infants aged ≥35 weeks gestation, with HLHS, admitted to our institution at age ≤5 days, between January 1, 2003, and January 1, 2013. Children with other cardiac abnormalities or other major comorbid conditions were excluded. Univariable and multivariable analyses were performed to determine the association between age at stage 1 palliation and major morbidity, mortality, and hospital reimbursement. RESULTS: One hundred thirty-four children met inclusion criteria. Mortality was 7.5% (n = 10). Forty-three percent (n = 58) experienced major morbidity. Median costs were $97,000, in 2013 dollars (interquartile range, $72,000-$151,000). Median age at operation was 5 days (interquartile range, 3-7 days; full range, 1-14 days). All deaths occurred in patients operated on between 4 and 8 days of life. For every day later that surgery was performed, the odds of major morbidity rose by 15.7% (95% confidence interval, 2.5%-30.7%; P = .018) and costs rose by 4.7% (95% confidence interval, 0.9%-8.2%; P < .014). CONCLUSIONS: Delay of stage 1 palliation for neonates with HLHS is associated with increased morbidity and health care costs, even within the first 2 weeks of life.

BACKGROUND: Hypoplastic left heart syndrome (HLHS) is not only a devastating disease, but also the most expensive birth defect managed in the US. Nosocomial bloodstream infections (NBIs) are common in neonates with HLHS. We examined the effects of NBIs on in-hospital mortality, length of stay, and costs for late preterm and term infants with HLHS undergoing stage 1 palliation, at both individual patient and hospital levels. METHODS: We conducted a retrospective study of infants 35 weeks or greater gestation with HLHS, admitted to our institution January 1, 2003 to January 1, 2013. Children with other cardiac abnormalities, major comorbid conditions, or perinatal infections were excluded. Univariable and multivariable analyses were performed. To estimate the effects of reduced NBI incidence on resource utilization, predictive models were used. RESULTS: One hundred forty-three children met inclusion criteria. In-hospital mortality was 9.1% (n = 13). Postoperative infection was observed in 12.6% (n = 18). Median length of stay was 23 days for survivors (IQR, 17 to 40; range, 9 to 132). Median costs were $83,000 for survivors, in 2013 dollars (IQR, $62,000 to $123,000; range, $17,000 to $517,000). NBIs were not associated with changes in mortality. In multivariable analyses, at a patient level NBIs were associated with a 74% increase in length of stay (95% confidence interval [CI], 31% to 132%, p < 0.001) and a 65% increase in costs (95% CI, 28% to 114%, p < 0.001). On a hospital level, in this cohort a 50% reduction in the incidence of NBIs would be expected to yield a 4.3% decrease in average length of stay and a 3.8% decrease in average in-patient costs. CONCLUSIONS: Nosocomial bloodstream infections in neonates with HLHS are associated with large increases in lengths of stay and costs on a patient level, but not a hospital level. For hospitals without particularly high incidences, studies are needed to identify additional targets for quality improvement.

OBJECTIVES: This study sought to examine the impact of surgical timing on major morbidity and hospital reimbursement for late preterm and term infants with dextrotransposition of the great arteries (d-TGA). BACKGROUND: Neonatal arterial switch operation is the standard of care for d-TGA. Little is known about the effects of age at operation on clinical outcomes or costs for these neonates. METHODS: We conducted a retrospective cohort study of infants at ≥36 weeks' gestation, with d-TGA, with or without ventricular septal defects, admitted to our institution at 5 days of age or younger, between January 1, 2003 and October 1, 2012. Children with other cardiac abnormalities or other major comorbid conditions were excluded. Univariable and multivariable analyses were performed to determine the effects of age at operation on major morbidity and hospital reimbursement. RESULTS: A total of 140 infants met inclusion criteria. Reimbursement data were available for them through January 1, 2012 (n = 128). The mortality rate was 1.4% (n = 2). Twenty percent (n = 28) experienced a major morbidity. The median costs were $60,000, in 2012 dollars (range: $25,000 to $549,000). The median age at operation was 5 days (range: 1 to 12 days). For every day later that surgery was performed, beyond day of life 3, the odds of major morbidity increased by 47% (range: 23% to 66%, p < 0.001) and costs increased by 8% (range: 5% to 11%, p < 0.001), after considering the effects of sex, birth weight, gestational age, year at which surgery was performed, transfer, weekend admission, insurance, surgeon, septostomy, bypass and cross-clamp times, and the presence of ventricular septal defects or abnormal coronary anatomy. CONCLUSIONS: Delay of neonatal arterial switch operation beyond 3 days is significantly associated with increased morbidity and healthcare costs.
