BACKGROUND: Long-term survival after spinal cord injury (SCI) has been extensively studied in the US and UK. OBJECTIVE: To compare SCI epidemiology and survival results between the US and UK for the same time period and patient groups. METHODS: We restricted attention to persons injured at ages 18 and older who had survived at least 2 years post injury and were not ventilator dependent. We performed survival analysis using logistic regression on person-year data with time-dependent covariates. The resulting mortality rates were used to construct life tables in order to obtain life expectancies. RESULTS: The average age at injury, percentage male, and level/grade of injury were rather similar between the two countries. After adjustment for risk factors, UK mortality was 85% of that in the US (95% c.i. 80% to 91%, p < 0.0001). Mortality increased by 0.3% per year over the 1980 to 2012 study period (HR = 1.003); this was not statistically significant (p = 0.44). The US and UK life expectancies are nearly the same percentage of their respective general population values, differing by at most 2%. CONCLUSION: Long-term mortality after SCI in the UK is roughly 15% lower than that in the US. The general population mortality in the UK is also approximately 15% lower, however, and thus the percentages of normal life expectancy in the two countries prove to be strikingly similar.

The COVID-19 pandemic’s effects on mental health interact with preexisting health risks and disparities to impact varying populations differently. This study explored the relationship between demographic variables (e.g., ethnicity, sexual orientation, and disability status), distress and mental health (e.g., depression, anxiety, somatic complaints, and pandemic distress), and vulnerability factors for COVID-19 (e.g., personal health vulnerabilities, community members’ health vulnerabilities, and environmental exposure risks at work or home). An online cross-sectional study was conducted from 18 June to 17 July 2020, reflecting the impact of early phase COVID-19 pandemic and related shelter-in-place measures in the United States. Participants were adults residing in the United States (N = 594), with substantial subsamples (N ≥ 70) of American Indian, Asian American, African-American, and Hispanic and/or Latinx participants, as well as people with disabilities and sexual minorities. Outcomes measured were depression, hopelessness, somatic complaints, anxiety-related disorders, locus of control (LOC), and a novel measure of pandemic-related distress. Data were analyzed using analyses of covariance (ANCOVA), chi-square test, and correlation coefficients. Generally, younger individuals, and those with less financial power—across all identities—suffered more distress. When controlling for age, lower financial power was associated with higher scores on the Center for Epidemiologic Studies Depression Scale-Revised (CESD-R; r = –0.21, p = < 0.001), Beck Hopelessness Scale (BHS; r = –0.17, p < 0.001), Patient Health Questionnaire-15 (PHQ-15; r = –0.09, p = 0.01), Screen for Child Anxiety Related Emotional Disorders for Adults Panic Disorder (SCARED-A PD; r = –0.14, p < 0.001), SCARED-A generalized anxiety disorder (GAD; r = –0.13, p = 0.002), SCARED-A obsessive–compulsive disorder (OCD; r = –0.08, p = 0.04), and the COVID-19 Pandemic Distress restriction/disconnection scale (C19PDS; r = –0.10, p = 0.009). In addition, disparities were found, in general, for marginalized identities by gender, sexual orientation, and disability status. Importantly, each ethnicity subsample showed a unique pattern of relationships between COVID-19 risk variables and mental health symptoms. The results support the hypothesis that any pandemic may amplify preexisting social and financial disparities. Overall, interventions at the clinical, governmental, or health equity level should take into consideration the needs of vulnerable groups. [ABSTRACT FROM AUTHOR]

Introduction: Non-Alcoholic Steatohepatitis is an increasing reason for liver transplantation in the western world. Knowledge of recipient life expectancy may assist in prudent allocation of a relatively scarce supply of donor livers. Research Questions: We calculated life expectancies for Non-alcoholic steatohepatitis (NASH) patients both at time of transplant and one year later, stratified by key risk factors, and examined whether survival has improved in recent years. Design: Data on 6635 NASH patients who underwent liver transplantation in the MELD era (2002-2018) from the United States OPTN database were analyzed using the Cox proportional hazards regression model and life table methods. Results: Factors related to survival were age, presence of diabetes or hepatic encephalopathy (HE), and whether the patient required dialysis in the week prior to transplant. Other important factors were whether the patient was working, hospitalization prior to transplant, ventilator support, and length of hospital stay (LOS). Survival improved over the study period at roughly 4.5% per calendar year during the first year posttransplant, though no improvement was observed in those who had survived one year. Conclusion: Life expectancy in NASH transplant patients was much reduced from normal, and varied according to age, medical factors, status at transplant, and post transplant course. Over the 17-year study period, patient survival improved markedly during the first year posttransplant, though not thereafter. The results given here may prove helpful in medical decision-making regarding treatment for both liver disease and other medical conditions, as they provide both clinicians and their patients with evidence-based information on prognosis.

Background: Alcohol-associated liver disease is the leading cause of liver transplantation in the western world. For these patients we calculated life expectancies both at time of transplant and several years later, stratified by key risk factors, and determined if survival has improved in recent years. Methods: Data on 14 962 patients with alcohol-associated liver disease who underwent liver transplantation in the MELD era (2002-2018) from the United States Organ Procurement and Transplantation Network database were analyzed using the Cox proportional hazards regression model and life table methods. Results: Demographic and past medical history factors related to survival were patient age, presence of diabetes or severe hepatic encephalopathy, and length of hospital stay. Survival improved over the study period, at roughly 3% per calendar year during the first 5 years posttransplant and 1% per year thereafter. Conclusions: Life expectancy in transplanted patients with alcohol-associated liver disease was much reduced from normal, and varied according to age, medical risk factors, and functional status. Survival improved modestly over the study period. Information on patient longevity can be helpful in making treatment decisions. [ABSTRACT FROM AUTHOR]

Background: Hepatocelluar carcinoma typically occurs with underlying cirrhosis. However roughly 20% of cases arise in a non-cirrhotic liver. There is limited literature that addresses the long-term survival of the narrow subgroup who received transplantation. For such patients we sought to calculate life expectancies both at time of transplant and several years later, stratified by key risk factors, and to determine if survival has improved in recent years. Such information can be helpful in making treatment decisions. Methods: Data on 4,373 non-cirrhotic HCC patients who underwent liver transplantation in the MELD era (2002-2018) from the United States OPTN database were analyzed using the Cox proportional hazards regression model and life table methods. Results: Demographic and past medical history factors related to survival were patient age, donor age over 20, and the presence of ascites or severe hepatic encephalopathy. Survival did not vary by race or sex. HCC-specific factors significantly related to survival were the total number of tumors, extrahepatic spread, lymph node involvement, satellite lesions, micro- or macrovascular invasion, tumor differentiation (grade), and pre-transplant treatment. Survival improved over the study period, at 4% per calendar year during the first 5 years post transplant and 1% per year thereafter. Conclusions: Life expectancy in non-cirrhotic HCC transplant patients is much reduced from normal, and varies according to age and tumor-related factors. Survival improved modestly over the study period. [ABSTRACT FROM AUTHOR]

Background: Hepatocelluar carcinoma, the most common primary liver cancer, has a historically dire prognosis. For hepatic cancer patients with cirrhosis who underwent liver transplantation, we sought to calculate life expectancies both at time of transplant and several years later, stratified by some key variables, and to determine if survival has improved in recent years. Methods: Data on 13,797 hepatic cancer patients with cirrhosis who underwent liver transplantation in the MELD era (2002-2018) from the US Organ Procurement and Transplantation Network database were analyzed using the Cox proportional hazards regression model and life table methods. Results: The major factors related to survival were age, donor age, transplant year, diabetes, functional status, and the presence of severe hepatic encephalopathy. Survival was significantly worse with increasing age and decreasing functional status level. There was no significant difference in survival between males and females. Survival improved over the study period, at 5% per calendar year during the first 5 years post transplant, and 1% per year thereafter. Conclusions: Life expectancies were markedly reduced from normal, even among 5-year survivors with the most favorable characteristics. Survival improved modestly over the years 2002-2018.

BACKGROUND: Although some have suggested that kernicterus disappeared in the United States in the 1970s to 1980s and dramatically reappeared in the 1990s, population-based data to support such a resurgence are lacking. METHODS: We used diagnosis codes on data collection forms from the California Department of Developmental Services (DDS) to identify kernicterus cases among children born from 1988 to 1997. We examined kernicterus mortality trends in the United States from 1979 to 2006 using death certificate data from the National Center for Health Statistics. RESULTS: We identified 25 cases of physician-diagnosed kernicterus. This figure was augmented to reflect estimates of cases lost to infant mortality, yielding incidence estimates of 1 in 200 000 California live births, 1 in 2500 among children who received services from DDS, and 1 in 400 children with cerebral palsy. There was no significant trend in kernicterus incidence from 1988 to 1997 (P = .77). Incidence before and after the 1994 publication of the AAP practice parameter for hy- perbilirubinemia in healthy term infants was not significantly different (P = .92). Nationally, there were 3 reported infant deaths from kernicterus in 1994 and 2 or fewer in the other 28 years from 1979 to 2006 (0.28 deaths per million live births): there was no significant increase in kernicterus mortality over this period. CONCLUSION: Data from California do not support a resurgence of kernicterus in the 1990s. Deaths from kernicterus in the United States have remained rare, with no apparent increase during the last 25 years. [ABSTRACT FROM AUTHOR]

Objective: To update the life expectancy estimates according to age, sex, mobility, and feeding skills reported in the 2015 study of Brooks et al. To examine trends in survival over the past decade., Design: Observational cohort study., Setting: Poisson regression and life table analysis applied to long-term follow-up data on United States (US) Traumatic Brain Injury (TBI) Model Systems patients recorded in the national database. Functional mobility and feeding skills were assessed with FIM., Participants: A total of 14,803 persons with TBI during the years 1988-2019 who underwent inpatient rehabilitation and provided at least 1 long-term assessment of functional skills 1 year or more postinjury (N=14,803)., Interventions: Not applicable., Main Outcome Measures: Survival, mortality rates, and life expectancy., Results: Life expectancy was lower than that of the age- and sex-matched general population. Older age and severity of functional impairments were risk factors for mortality (both P<.0001 in regression models). Among ambulatory individuals, mortality was 51% (95% confidence interval, 35%-69%) higher in men than women. Life expectancy of 20-year-old women who walked well (FIM ambulation score 7) was 55 (SE=0.8) additional years to age 75, representing a reduction of 6.9 years from the normal general population figure. For 20-year-old men who walked well, the life expectancy was 49 (SE=0.5) additional years, representing a reduction of 8.1 years from normal. Life expectancies for men and women who did not walk and were fed by others were much lower. There was no significant change in mortality rates during the study period (hazard ratio, 1.008; P=.07)., Conclusions: There has been no significant change in the long-term survival of persons with TBI in the US since the late 1980s. The life expectancies reported here are similar to those reported in the 2015 study of Brooks et al, although they are more precise because of the larger sample size and longer follow-up., (Copyright © 2021 The American Congress of Rehabilitation Medicine.

Importance: Mild traumatic brain injury (mTBI) affects millions of Americans each year. Lack of consistent clinical practice raises concern that many patients with mTBI may not receive adequate follow-up care., Objective: To characterize the provision of follow-up care to patients with mTBI during the first 3 months after injury., Design, Setting, and Participants: This cohort study used data on patients with mTBI enrolled in the Transforming Research and Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI) study between February 26, 2014, and August 25, 2016. We examined site-specific variations in follow-up care, the types of clinicians seen by patients receiving follow-up care, and patient and injury characteristics associated with a higher likelihood of receiving follow-up care. The TRACK-TBI study is a prospective, multicenter, longitudinal observational study of patients with TBI presenting to the emergency department of 1 of 11 level I US trauma centers. Study data included patients with head trauma who underwent a computed tomography (CT) scan within 24 hours of injury, had a Glasgow Coma Scale score of 13 to 15, were aged 17 years or older, and completed follow-up care surveys at 2 weeks and 3 months after injury (N = 831)., Main Outcomes and Measures: Follow-up care was defined as hospitals providing TBI educational material at discharge, hospitals calling patients to follow up, and patients seeing a physician or other medical practitioner within 3 months after the injury. Unfavorable outcomes were assessed with the Rivermead Post Concussion Symptoms Questionnaire., Results: Of 831 patients (289 [35%] female; 483 [58%] non-Hispanic white; mean [SD] age, 40.3 [16.9] years), less than half self-reported receiving TBI educational material at discharge (353 patients [42%]) or seeing a physician or other health care practitioner within 3 months after injury (367 patients [44%]). Follow-up care varied by study site; adjusting for patient characteristics, the provision of educational material varied from 19% to 72% across sites. Of 236 patients with a positive finding on a CT scan, 92 (39%) had not seen a medical practitioner 3 months after the injury. Adjusting for injury severity and demographics, patient admission to the hospital ward or intensive care unit, patient income, and insurance status were not associated with the probability of seeing a medical practitioner. Among the patients with 3 or more moderate to severe postconcussive symptoms, only 145 of 279 (52%) reported having seen a medical practitioner by 3 months., Conclusions and Relevance: There are gaps in follow-up care for patients with mTBI after hospital discharge, even those with a positive finding on CT or who continue to experience postconcussive symptoms.

Objectives: To compute the life expectancy of persons with traumatic brain injury (TBI) based on validated prognostic models from 2 cohorts, to compare mortality and life expectancy of persons with TBI with those of the U.S. general population, and to investigate trends toward improved survival over the last 2 decades., Design: Survival analysis., Setting: Postdischarge from rehabilitation units and long-term follow-up at regional centers., Participants: Two cohorts of long-term survivors of TBI (N=12,481): the Traumatic Brain Injury Model Systems (TBIMS) cohort comprised 7365 persons who were admitted to a TBIMS facility with moderate to severe TBI and were assessed at ≥1 years postinjury, and the California Department of Developmental Services (CDDS) cohort comprised 5116 persons who sustained a TBI and received long-term services from the CDDS., Interventions: Not applicable., Main Outcome Measures: Life expectancy., Results: The estimates of age-, sex-, and disability-specific life expectancy of persons with TBI derived from the CDDS and TBIMS were similar. The estimates of age- and sex-specific life expectancy were lower than those of the U.S. general population. Mortality rates of persons with TBI were higher than those of the U.S. general population. Mortality rates did not improve and the standardized mortality ratio increased over the study period from 1988 to 2010., Conclusions: Life expectancy of persons with TBI is lower than that of the general population and depends on age, sex, and severity of disability. When compared, the survival outcomes in the TBIMS and CDDS cohorts are remarkably similar. Because there have been no marked trends in the last 20 years, the life expectancies presented in this article may remain valid in the future., (Copyright © 2015 American Congress of Rehabilitation Medicine.

Objectives: To develop prognostic models for long-term survival in adults with traumatic brain injury (TBI) and to assess their external validity in 2 independent populations., Design: Survival analysis., Setting: Post-discharge from rehabilitation units and long-term follow-up at regional centers., Participants: Two cohorts of long-term survivors of TBI (N=12,481): the Traumatic Brain Injury Model Systems (TBIMS) cohort comprised 7365 persons who were admitted to a TBIMS facility and were assessed at ≥1 years postinjury, and the California Department of Developmental Services (CDDS) cohort comprised 5116 persons who sustained a TBI and received long-term services from the CDDS., Interventions: Not applicable., Main Outcome Measures: Survival/mortality., Results: Older age, male sex, and severity of disability in walking and feeding were significant predictors of increased long-term mortality rates (all P<.05, both databases). The CDDS model predicted 623 deaths for persons in the TBIMS cohort, with an observed-to-expected ratio of .94 (95% confidence interval [CI], 0.87-1.02). The TBIMS model predicted a total of 525 deaths for persons in the CDDS cohort, with an observed-to-expected ratio of 1.08 (95% CI, 0.99-1.17). Regression calibration statistics were satisfactory, and both models ranked survival times well from shortest to longest (TBIMS: C index, .78; 95% CI, .76-.80; CDDS: C index, .80; 95% CI, .78-.82)., Conclusions: Long-term survival prognosis in TBI is related to age, sex, and severity of disability. When compared on the basis of these factors, the survival estimates derived from the TBIMS and CDDS cohorts are found to be similar. The close agreement between model predictions and actual mortality rates confirm the external validity of the prognostic models presented herein., (Copyright © 2015 American Congress of Rehabilitation Medicine.

Background: Hospital admission data indicate that the angioedema incidence has increased during the past several decades. Little is known about mortality trends., Objectives: To count the number of deaths associated with angioedema in the United States, investigate correlations with age, sex, race, and other contributory causes, and analyze trends from 1979 to 2010., Methods: All US death certificates in which angioedema was listed as an underlying or contributing cause of death during 1979 to 2010 were analyzed. Age-adjusted mortality rates were analyzed by age, sex, and race. Other conditions designated as the underlying cause of death were investigated., Results: From 1979 to 2010, there were 5,758 deaths in which angioedema was listed as a contributing cause. The age-adjusted death rate for hereditary angioedema decreased from 0.28 (95% confidence interval [CI] 0.25-0.32) to 0.06 (95% CI 0.05-0.08) per million persons per year. Conversely, mortality for angioedema increased from 0.24 (95% CI 0.21-0.27) to 0.34 (95% CI 0.31-0.37) per million. Blacks constituted 55% of angioedema deaths that were associated with use of angiotensin-converting enzyme inhibitors. On death certificates that listed hereditary angioedema as the underlying cause of death, cancer (frequently lymphoma or leukemia) was the second most commonly listed cause., Conclusion: Angioedema-associated deaths were very rare from 1979 to 2010. Hereditary angioedema deaths became even more so, whereas nonhereditary angioedema deaths increased. Risks associated with angiotensin-converting enzyme inhibitors were higher in blacks. Lack of specific coding for acquired angioedema most likely explains the observed association between cancer and hereditary angioedema. In the future, more granular coding systems may help distinguish hereditary from acquired angioedema., (Copyright © 2014 American College of Allergy, Asthma & Immunology. Published by Elsevier Inc.

Aim: To determine whether the trend of improved survival among individuals with cerebral palsy (CP) in California during the 1980s and 1990s has continued during the most recent decade., Method: In an observational cohort study we evaluated individuals with CP, aged 4 years and older, who were clients of the California Department of Developmental Services. Medical diagnoses, functional disabilities, and special health care requirements were assessed with Client Development Evaluation Reports made between 1983 and 2010. Trends in birth cohort survival were analyzed with Kaplan-Meier curves and Cox regression. Calendar year period effects were analyzed with Poisson regression., Results: A total of 51,923 persons with CP (28,789 males [55%], 23,134 females [45%]; mean age 14y 11mo, SD 14y 1mo, range 4y 0mo to 96y 10mo) collectively contributed 662,268 years of follow-up. There were 7690 deaths for an overall mortality rate of 11.6 per 1000 persons per year. No significant birth cohort effects on survival were observed in 4-year-olds who had no severe disabilities. By contrast, children who did not lift their heads in prone position who were born in more recent years had significantly lower mortality rates (Cox hazard ratio 0.971, p<0.001) than those with comparable disabilities born earlier. With regard to calendar year period effects, we found that age-, sex-, and disability-specific mortality rates declined by 1.5% (95% CI 0.9-2.1) year-over-year from 1983 to 2010. The estimate increased to 2.5% (95% CI 1.9-3.1) per year when we additionally controlled for tube-feeding status. Mortality rates in tube fed adolescents and adults, ages 15 to 59 years, declined by 0.9% (95% CI, 0.4-1.4) per year. No improvement was observed for adolescents or adults who fed orally or for those over age 60. In fact, the ratio of age-specific mortality rates for these latter groups to those in the general population, increased by 1.7% (95% CI 1.3-2.0) per year during the study period., Interpretation: The trend toward improved survival has continued throughout the most recent decade. Declines in CP childhood mortality are comparable to the improvements observed in the United States general population (i.e. the mortality ratio in childhood has remained roughly constant over the last three decades). In contrast, the mortality ratio for most adolescents and adults with CP, relative to the general population, has increased., (© 2014 Mac Keith Press.)
