RESUMO

RATIONALE & OBJECTIVE: Reasons for transfer from peritoneal dialysis (PD) to hemodialysis (HD) remain incompletely understood. Among incident and prevalent patients receiving PD, we evaluated the association of clinical factors, including prior treatment with HD, with PD technique survival. STUDY DESIGN: Retrospective cohort study. SETTING & PARTICIPANTS: Adults who initiated PD at a Dialysis Clinic, Inc (DCI) outpatient facility between January 1, 2010, and September 30, 2019. EXPOSURE: The primary exposure of interest was timing of PD start, categorized as PD-first, PD-early, or PD-late. Other covariates included demographics, clinical characteristics, and routine laboratory results. OUTCOME: Modality switch from PD to HD sustained for more than 90 days. ANALYTICAL APPROACH: Multivariable Fine-Gray models with competing risks and time-varying covariates, stratified at 9 months to account for lack of proportionality. RESULTS: Among 5,224 patients who initiated PD at a DCI facility, 3,174 initiated dialysis with PD ("PD-first"), 942 transitioned from HD to PD within 90 days ("PD-early"), and 1,108 transitioned beyond 90 days ("PD-late"); 1,472 (28%) subsequently transferred from PD to HD. The PD-early and PD-late patients had a higher risk of transfer to HD as compared with PD-first patients (in the first 9 months: adjusted hazard ratio [AHR], 1.51 [95% CI, 1.17-1.96] and 2.41 [95% CI, 1.94-3.00], respectively; and after 9 months: AHR, 1.16 [95% CI, 0.99-1.35] and AHR, 1.43 [95% CI, 1.24-1.65], respectively). More peritonitis episodes, fewer home visits, lower serum albumin levels, lower residual kidney function, and lower peritoneal clearance calculated with weekly Kt/V were additional risk factors for PD-to-HD transfer. LIMITATIONS: Missing data on dialysis adequacy and residual kidney function, confounded by short PD technique survival. CONCLUSIONS: Initiating dialysis with PD is associated with greater PD technique survival, though many of those who initiate PD-late in their dialysis course still experience substantial time on PD. Peritonitis, lower serum albumin, and lower Kt/V are risk factors for PD-to-HD transfer that may be amenable to intervention. PLAIN-LANGUAGE SUMMARY: Peritoneal dialysis (PD) is an important kidney replacement modality with several potential advantages compared with in-center hemodialysis (HD). However, a substantial number of patients transfer to in-center HD early on, without having experienced the quality-of-life and other benefits that come with sustained maintenance of PD. Using retrospective data from a midsize national dialysis provider, we found that initiating dialysis with PD is associated with longer maintenance of PD, compared with initiating dialysis with HD and a later switch to PD. However, many of those who initiate PD-late in their dialysis course still experience substantial time on PD. Peritonitis, lower serum albumin, and lower small protein removal are other risk factors for PD-to-HD transfer that may be amenable to intervention.

RESUMO

RATIONALE & OBJECTIVE: SARS-CoV-2 vaccine effectiveness and immunogenicity threshold associated with protection against COVID-19-related hospitalization or death in the dialysis population are unknown. STUDY DESIGN: Retrospective, observational study. SETTING & PARTICIPANTS: Adult patients without COVID-19 history receiving maintenance dialysis through a national dialysis provider and treated between February 1 and December 18, 2021, with follow-up through January 17, 2022. PREDICTOR: SARS-CoV-2 vaccination status. OUTCOMES: All SARS-CoV-2 infections, composite of hospitalization or death following COVID-19. ANALYTICAL APPROACH: Logistic regression was used to determine COVID-19 case rates and vaccine effectiveness. RESULTS: Of 16,213 patients receiving dialysis during the study period, 12,278 (76%) were fully vaccinated, 589 (4%) were partially vaccinated, and 3,346 (21%) were unvaccinated by the end of follow-up. Of 1,225 COVID-19 cases identified, 550 (45%) occurred in unvaccinated patients, and 891 (73%) occurred during the Delta variant-dominant period. Between the pre-Delta period and the Delta-dominant period, vaccine effectiveness rates against a severe COVID-19-related event (hospitalization or death) were 84% and 70%, respectively. In the subset of 3,202 vaccinated patients with at least one anti-spike immunoglobulin G (IgG) assessment, lower anti-spike IgG levels were associated with higher case rates per 10,000 days and higher adjusted hazard ratios for infection and COVID-19-related hospitalization or death. LIMITATIONS: Observational design, residual biases, and confounding may exist. CONCLUSIONS: Among maintenance dialysis patients, SARS-CoV-2 vaccination was associated with a lower risk of COVID-19 diagnosis and associated hospitalization or death. Among vaccinated patients, a low anti-spike IgG level is associated with worse COVID-19-related outcomes.

RESUMO

Perinatal mood disorders (PMDs) are common, yet many patients are undertreated. The Massachusetts Child Psychiatry Access Program (MCPAP) for Moms is designed to increase clinicians' willingness to address PMDs. We examined utilization of MCPAP for Moms and associations with PMDs treatment, including the more complex bipolar disorder (BD). Analyses of MCPAP for Moms data examined utilization from 7/2014 to 6/2020 and associated treatment outcomes. Participants were clinicians (n = 1006) in obstetrics/gynecology, family medicine, and pediatrics. Encounters included (1) resource and referrals and (2) psychiatric consultations (program psychiatrist consultation with clinicians or patients). Utilization sub-groups were identified using group-based trajectory modeling. Higher utilization of MCPAP for Moms was associated with increased rates of treating PMDs (incidence rate ratio [IRR] = 1.07, 95% CI: 1.06-1.07). Examining by encounter type, psychiatric consultations resulted in more frequent rates of clinicians treating PMDs than resource and referral encounters. Utilization of direct patient consultation was associated with the greatest increase in rates of clinicians treating BD (IRR = 2.12, 95% CI: 1.82-2.41). Clinicians with highest utilization rates of psychiatric consultations longitudinally had strongest predictive associations with providing direct mental healthcare to patients with BD (IRR = 13.5, 95% CI: 4.2-43.2). Utilization of MCPAP for Moms facilitates clinicians' ability to provide mental health treatment to patients.

RESUMO

BACKGROUND: About 7 million people, 2.8% of US adults, have bipolar disorder (BD). While second-generation antipsychotics (SGA) are indicated as acute and maintenance treatments for BD, therapeutic success requires medication adherence and reported nonadherence estimates to range as high as 60%. Identifying patient risk factors for nonadherence is important for reducing it. OBJECTIVE: The objective of this study was to quantify the associations of risk factors, including social determinants of health, with SGA nonadherence among patients with BD. METHODS: In this cross-sectional study of 2015-2017 MassHealth Medicaid data, we examined several definitions of adherence and used logistic regression to identify risk factors for nonadherence (medication possession ratio <0.8) among all adults aged 18-64 diagnosed with BD who could be followed for 12 months following SGA initiation. RESULTS: Among 5197 patients, the mean (±SD) age was 37.7 (±11.4) years, and 42.3% were men. Almost half (47.7%) of patients were nonadherent to SGAs when measured by medication possession ratio. The prevalence of nonadherence peaked at middle age for men and younger for women. Nonadherence was less common among Massachusetts' Department of Mental Health clients (odds ratio=0.60, 95% confidence limit: 0.48-0.74) and among those who used other psychotropic medications (odds ratios between 0.45 and 0.81); in contrast, increase in neighborhood socioeconomic stress was associated with increased odds of nonadherence. CONCLUSIONS/IMPLICATIONS: Adherence to SGA treatment is suboptimal among people with BD. Recognizing risk factors, including those related to social determinants of health, can help target interventions to improve adherence for people at high risk and has implications for adherence-based quality measures.

RESUMO

IMPORTANCE: Better patient management can reduce emergency department (ED) use. Performance measures should reward plans for reducing utilization by predictably high-use patients, rather than rewarding plans that shun them. OBJECTIVE: The objective of this study was to develop a quality measure for ED use for people diagnosed with serious mental illness or substance use disorder, accounting for both medical and social determinants of health (SDH) risks. DESIGN: Regression modeling to predict ED use rates using diagnosis-based and SDH-augmented models, to compare accuracy overall and for vulnerable populations. SETTING: MassHealth, Massachusetts' Medicaid and Children's Health Insurance Program. PARTICIPANTS: MassHealth members ages 18-64, continuously enrolled for the calendar year 2016, with a diagnosis of serious mental illness or substance use disorder. EXPOSURES: Diagnosis-based model predictors are diagnoses from medical encounters, age, and sex. Additional SDH predictors describe housing problems, behavioral health issues, disability, and neighborhood-level stress. MAIN OUTCOME AND MEASURES: We predicted ED use rates: (1) using age/sex and distinguishing between single or dual diagnoses; (2) adding summarized medical risk (DxCG); and (3) further adding social risk (SDH). RESULTS: Among 144,981 study subjects, 57% were women, 25% dually diagnosed, 67% White/non-Hispanic, 18% unstably housed, and 37% disabled. Utilization was higher by 77% for those dually diagnosed, 50% for members with housing problems, and 18% for members living in the highest-stress neighborhoods. SDH modeling predicted best for these high-use populations and was most accurate for plans with complex patients. CONCLUSION: To set appropriate benchmarks for comparing health plans, quality measures for ED visits should be adjusted for both medical and social risks.

RESUMO

Hepatocellular carcinoma is one of the most common cancer types worldwide. In cases of advanced-stage disease, sorafenib is considered the treatment of choice. However, resistance to sorafenib remains a major obstacle for effective clinical application. Based on integrated phosphoproteomic and The Cancer Genome Atlas (TCGA) data, we identified a transcription factor, Y-box binding protein-1 (YB-1), with elevated phosphorylation of Ser102 in sorafenib-resistant HuH-7R cells. Phosphoinositide-3-kinase (PI3K) and protein kinase B (AKT) were activated by sorafenib, which, in turn, increased the phosphorylation level of YB-1. In functional analyses, knockdown of YB-1 led to decreased cell migration and invasion in vitro. At the molecular level, inhibition of YB-1 induced suppression of zinc-finger protein SNAI1 (Snail), twist-related protein 1 (Twist1), zinc-finger E-box-binding homeobox 1 (Zeb1), matrix metalloproteinase-2 (MMP-2) and vimentin levels, implying a role of YB-1 in the epithelial-mesenchymal transition (EMT) process in HuH-7R cells. Additionally, YB-1 contributes to morphological alterations resulting from F-actin rearrangement through Cdc42 activation. Mutation analyses revealed that phosphorylation at S102 affects the migratory and invasive potential of HuH-7R cells. Our collective findings suggest that sorafenib promotes YB-1 phosphorylation through effect from the EGFR/PI3K/AKT pathway, leading to significant enhancement of hepatocellular carcinoma (HCC) cell metastasis. Elucidation of the specific mechanisms of action of YB-1 may aid in the development of effective strategies to suppress metastasis and overcome resistance.

RESUMO

OBJECTIVE: Conceptually, access to primary care (through insurance) should reduce emergency department (ED) visits for primary care sensitive (PCS) conditions. We sought to identify characteristics of insured Massachusetts residents associated with PCS ED use, and compare such use for public versus private insurees. POPULATION AND SETTING: People under age 65 in the Massachusetts All-Payer Claims Data, 2011-2012. STUDY DESIGN: Retrospective, observational analysis of PCS ED use with nonurgent, urgent/primary care treatable, and urgent/potentially avoidable visits being considered PCS. We predicted utilization in 2012 using multivariable regression models and data available in 2011 administrative records. PRINCIPAL FINDINGS: Among 2,269,475 nonelderly Massachusetts residents, 40% had public insurance. Among public insurees, PCS ED use was higher than for private (mean, 36.5 vs. 9.0 per 100 persons; adjusted risk ratio, 2.53; 95% confidence limits, 2.49-2.56), while having any primary care visit was less common (70% vs. 83%), as was having any visit to one's own (attributed) primary care provider (38% vs. 44%). CONCLUSIONS: Public insurance was associated with less access to primary care and more PCS ED use; statewide labor shortages and low reimbursement rates from public insurance may have provided inadequate access to care that might otherwise have helped reduce PCS ED use.

RESUMO

RATIONALE & OBJECTIVE: The relationship between tobacco smoking and comorbid condition outcomes in hemodialysis (HD) patients is not well understood. This study examined the association of tobacco smoking status with hospitalization and mortality in HD patients. STUDY DESIGN: Retrospective cohort study. SETTING & PARTICIPANTS: Adult HD patients at 2,223 US dialysis centers with HD vintage of 30 days or less who completed a tobacco smoking status survey as part of standard care between April 2013 and June 2015. PREDICTOR: Tobacco smoking category: never smoked, currently living with smoker, former smoker, moderate smoker (<1 pack per day), or heavy smoker (≥1 pack per day). OUTCOMES: Death and hospital admissions within 2 years of the tobacco smoking survey. ANALYTICAL APPROACH: Kaplan-Meier analysis and Cox proportional hazards regression for time to death; cumulative incidence function and Cox proportional hazards regression for time to first hospitalization; negative-binomial regression for number of hospitalizations. RESULTS: Of 22,230 patients studied, 13% were active smokers. Mortality probabilities increased with greater exposure to smoking (17%, 22%, 23%, and 27% for never, moderate, former, and heavy smokers, respectively; P<0.001), as did incidence rates for first hospitalization (23%, 27%, 27%, and 30%, respectively; P<0.001). Compared to never smoked, heavy smokers had the highest mortality rate (HR for heavy smokers, 1.41 [95% CI, 1.18-1.69]; HR for moderate smokers, 1.39 [95% CI, 1.24-1.55]; HR for former smokers, 1.19 [95% CI, 1.11-1.28]). Living with a smoker was not associated with mortality (HR, 0.93; 95% CI, 0.72-1.22). HRs for first hospitalization followed similar patterns. The incidence rate of mortality for active smokers with diabetes was 173.7/1,000 patient-years and 103.5/1,000 patient-years for those who never smoked (incidence rate ratio, 1.68; P<0.001). LIMITATIONS: Self-reported survey without detailed history of smoking/cessation. CONCLUSIONS: Risks for death and hospitalization are elevated among HD patients who smoke, being highest among younger individuals and those with diabetes. Second-hand smoke was not associated with poor clinical outcomes.

RESUMO

BACKGROUND: Quality of life (QOL) is an important metric of high-quality dialysis care. QOL is commonly measured by the Short Form 36 Questionnaire (SF-36), which provides two summary scores: a mental component score (MCS) and a physical component score (PCS). Poor QOL is associated with mortality in dialysis patients. Small studies show that changes in QOL also predicts mortality. We investigated whether changes in QOL over time are associated with mortality in a large cohort of maintenance hemodialysis patients. METHODS: This retrospective study was conducted in 1017 outpatient dialysis facilities. Over 10,000 hemodialysis patients completed two SF-36 surveys. We compared 1-year morality rates in those whose MCS or PCS increased or decreased ±5 vs. those whose did not. RESULTS: For those who completed two surveys, mean score for PCS was unchanged, whereas MCS increased slightly (48.6 vs. 48.9, p = 0.05). Individual patients, however, showed marked variation. On the second survey, more than half of patients demonstrated a ± 5 point change in the PCS and/or MCS. After multivariate adjustment, a ≥ 5 decrease in MCS was associated with an increase in mortality (HR = 1.33, 95 % CI 1.18, 1.50). CONCLUSIONS: Clinicians should be aware that many patients experience a significant change in both the MCS and PCS on dialysis. A MCS decrease of ≥5 was associated with increased mortality. More study is needed to determine whether this is a causal relationship. Physicians should evaluate root causes and seek to mitigate declines in QOL whenever possible.

RESUMO

BACKGROUND: Patterns of early outcomes in peritoneal dialysis (PD) are not well studied and dialysis providers need to establish a baseline of key outcomes for continuous quality improvement initiatives. STUDY DESIGN: Retrospective cohort study. SETTING & PARTICIPANTS: Incident PD patients from Fresenius Medical Care, North America from January 1 through December 31, 2009. FACTORS: Case-mix, comorbid illness, and baseline laboratory values. OUTCOMES: Death, hospitalization, peritonitis, and switch to hemodialysis (HD) within the first year on PD therapy. MEASUREMENTS: Event rates and outcome predictors. RESULTS: Of 1,677 incident PD patients, 1,313 started on PD therapy and 367 switched from HD therapy within the first 90 days. Normalized first-year event rates for mortality, switch to HD therapy, peritonitis, and hospitalization were 10, 27, 42, and 128 per 100 patient-years, respectively. 336 of 463 (72.6%) first peritonitis episodes and 637 of 939 (67.8%) first hospitalizations occurred within the first 6 months of PD treatment. Black race, higher body mass index, non-Hispanic ethnicity, peripheral vascular disease, and low weekly Kt/V associated with peritonitis risk. Dialysis vintage, female sex, diabetes, congestive heart failure, peripheral vascular disease, and history of limb amputation along with lower laboratory values for albumin, hemoglobin, and phosphorus and weekly Kt/V associated with hospitalization. Switchers to HD therapy (n=350) used central venous catheters 81.4% of the time as initial access (still 78.3% at 90 days later) because of lack of permanent access. LIMITATIONS: Residual confounding from unmeasured variables and exclusion of patients with a training day but who never started home PD therapy. CONCLUSIONS: Despite low first-year mortality, incident PD patients had high morbidity, particularly within the first 3-6 months. Increased focus to identify patients at greatest risk for peritonitis and hospitalization, as well as evaluation of care processes and implementation of preventive strategies, is required. Access planning for transition to HD therapy needs more attention, even during the first PD year.

RESUMO

Rationale & Objective: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections are likely underdiagnosed, but the degree of underdiagnosis among patients receiving maintenance dialysis is unknown. The durability of the immune response after the third vaccine dose in this population also remains uncertain. This descriptive study tracked antibody levels to (1) assess the rate of undiagnosed infections and (2) characterize seroresponse durability after the third dose. Study Design: Retrospective observational study. Setting & Participants: SARS-CoV-2-vaccinated patients receiving maintenance dialysis through a national dialysis provider. Immunoglobulin G spike antibodies [anti-spike immunoglobulin (Ig) G] titers were assessed monthly after vaccination. Exposures: Two and 3 doses of SARS-CoV-2 vaccine. Outcomes: Undiagnosed and diagnosed SARS-CoV-2 infections; anti-spike IgG titers over time. Analytical Approach: Undiagnosed SARS-CoV-2 infections were identified as an increase in anti-spike IgG titer of ≥100 BAU/mL, not associated with receipt of vaccine or diagnosed SARS-CoV-2 infection (by polymerase chain reaction test or antigen test). In descriptive analyses, anti-spike IgG titers were followed over time. Results: Among 2,703 patients without previous coronavirus disease 2019 (COVID-19) who received an initial 2-dose vaccine series, 271 had diagnosed SARS-CoV-2 infections (3.4 per 10,000 patient-days) and 129 had undiagnosed SARS-CoV-2 infections (1.6 per 10,000 patient-days). Among 1,894 patients without previous COVID-19 who received a third vaccine dose, 316 had diagnosed SARS-CoV-2 infections (7.0 per 10,000 patient-days) and 173 had undiagnosed SARS-CoV-2 infections (3.8 per 10,000 patient-days). In both cohorts, anti-spike IgG levels declined over time. Of the initial 2-dose cohort, 66% had a titer of ≥500 BAU/mL in the first month, with 24% maintaining a titer of ≥500 BAU/mL at 6 months. Of the third dose cohort, 95% had a titer of ≥500 BAU/mL in the first month after the third dose, with 77% maintaining a titer of ≥500 BAU/mL at 6 months. Limitations: The assays used had upper limits. Conclusions: Among patients receiving maintenance dialysis, about 1 in every 3 SARS-CoV-2 infections was undiagnosed. Given this population's vulnerability to COVID-19, ongoing infection control measures are needed. A 3-dose primary mRNA vaccine series optimizes seroresponse rate and durability. Plain-Language Summary: Patients receiving maintenance dialysis have been particularly vulnerable to COVID-19. Using serially measured antibodies, we found that a substantial proportion (about one-third) of SARS-CoV-2 infections among this population had been missed, both among those who had completed a 2-dose vaccine series and among those who had received a third vaccine dose. Such missed infections likely had only mild or minimal symptoms, but this failure to recognize all infections is concerning. Furthermore, vaccines have been effective among patients receiving dialysis, but our study additionally shows that the immune response wanes over time, even after a third dose. There is therefore a role for ongoing vigilance against this highly transmissible infection.

RESUMO

BACKGROUND: The relationship between severity of depressive symptoms reported by incident dialysis patients and first-year outcomes is not known. METHODS: We evaluated the association between self-report of depressive symptoms in incident hemodialysis patients admitted at Fresenius Medical Care North America facilities between 1 January and 31 December 2006 and mortality or withdrawal from dialysis for up to 1 year after the initial survey. The impact of depression scores calculated from two Short Form-36 (SF-36) questionnaires was determined independently of the mental and physical component scores, case-mix and laboratory variables using stepwise Cox models. RESULTS: We received 6415 SF-36 responses within 46±24 days of first dialysis from a cohort with a mean age of 62.3±15.2 years; 58% were diabetic, 45% were female and 69% were Caucasian. A 1-point increase in depression score was associated with unadjusted hazard ratio (HR) of 1.09 (1.03, 1.15) for mortality and 1.15 (1.05, 1.26) for withdrawal from dialysis. After adjustment, a 1-point increase in depression score had a mortality HR of 1.08 (1.01, 1.14) and for withdrawal 1.19 (1.08, 1.31). CONCLUSIONS: Depressive symptoms reported within the first 90 days of dialysis were associated with greater dialysis withdrawal and mortality risk over the succeeding year. Whether further evaluation for and treatment of depression during this early vulnerable period may improve symptoms, increase survival and decrease premature withdrawal from dialysis requires confirmation in prospective clinical trials.

RESUMO

Statutory management of juvenile sexual offenders demands reliable, valid methods for assessing the risk posed by these youth. This study examined the predictive validity of the J-SOAP-II using samples of adolescent and pre-adolescent boys who were wards of the Massachusetts Department of Social Services. The base rate for sexual recidivism among the adolescents (14-16%) is generally in line with what has been reported. The equivalent base rate for the pre-adolescents (25-28%), however, was notably higher. Although the J-SOAP-II was developed for adolescents, the scale also worked with the pre-adolescents in predicting sexual recidivism over 7 years, with AUC values of 0.77, 0.74, 0.77, and 0.80 for Scales 1, 3, 4, and Total among the pre-adolescents and AUC values of 0.80, 0.82, and 0.83 for Scales 1, 4, and Total among the adolescents. Discussion focuses on extant J-SOAP research and sample dependent variability, as well as social policy implications.

RESUMO

Purpose: Limited English proficiency adversely impacts people's ability to access health services. This study examines the association between English language proficiency and insurance access and use of a usual care provider after the implementation of the Affordable Care Act (ACA). Methods: Using cross-sectional data from the 2016 Medical Panel Expenditures Survey, we identified 24,099 adults (weighted n=240,035,048) and categorized them by self-reported English-language proficiency. We classified participants according to responses to: "How well do you speak English? Would you say… Very well; well; Not well; Not at all?" (having limited English proficiency: not well; not at all, English proficient: well; very well; and English only: not applicable) and "What language do you speak at home? Would you say… English, Spanish, Other." Using these two recoded variables, we created a variable with five categories: (1) Spanish speaking, with limited English proficiency, (2) other language speaking, with limited English proficiency, (3) Spanish speaking, English proficient, (4) other language speaking, English proficient, and (5) English only. Health insurance and usual care provider were determined by self-report. Results: Among those <65 years, the percent covered by public insurance (Spanish: 21%, Other languages: 28%, English only 14%), who were uninsured (Spanish: 46%, Other languages: 17%, English only: 8%), and who lacked a usual care provider (Spanish: 45%, Other languages: 35%, English only: 26%) differed by English language proficiency. Among those ≥65 years, fewer people with limited English proficiency relative to English only were dually covered by Medicare and private insurance (Spanish: 12%, Other languages: 15%, English only: 59%), and a higher percent lacked a usual care provider (Spanish: 15%, Other languages: 11%, English only: 7%). Differences persisted with adjustment for covariates. Conclusion: Post the ACA, persons with limited English proficiency remain at a risk of being uninsured relative to those who only speak English.

RESUMO

Long-term functional outcomes in young adults with facial burns remain poorly studied. This 5-year (2003-2008) prospective multicenter study includes burn survivors (age 19-30 years) who completed the Young Adult Burn Outcome Questionnaire (YABOQ) from 0 to 36 months after baseline survey administration. A composite canonical score was developed from 15 YABOQ domains using discriminant analysis, maximizing the difference at the baseline between burn-injured patients with face involved and not involved. A generalized linear model with the generalized estimation equation technique was used to track the changing pattern of the composite score over time. Individual domain scores with high correlation to the canonical score were used to evaluate recovery patterns in facial burns. A total of 153 burned (31% with face burns) and 112 nonburned subjects completed 620 questionnaires. Canonical analysis showed that early postburn, facial burns were associated with a difference in outcome, but this overall difference diminished over time. Regression analysis showed that for survivors with facial injury, Emotion and Sexual Function scores were persistently lower (worse), while Religion scores were persistently higher. Satisfaction with Role was initially better than the nonface burned group, but over time got worse, while Perceived Appearance was initially worse in the face burned group but this difference diminished over time. Social Function Limited by Appearance was initially similar between the groups, but over time the group with face burns scored lower. The overall difference in recovery between survivors with and without facial burns diminished over time while the individual domains had various patterns of recovery.

RESUMO

BACKGROUND: Statins are a class of medications that reduce cholesterol by inhibiting 3-hydroxy-3-methylglutaryl-coenzyme A reductase. Whether statins can benefit patients with dementia remains unclear because of conflicting results. We hypothesized that some of the confusion in the literature might arise from differences in efficacy of different statins. We used a large database to compare the action of several different statins to investigate whether some statins might be differentially associated with a reduction in the incidence of dementia and Parkinson's disease. METHODS: We analyzed data from the decision support system of the US Veterans Affairs database, which contains diagnostic, medication and demographic information on 4.5 million subjects. The association of lovastatin, simvastatin and atorvastatin with dementia was examined with Cox proportional hazard models for subjects taking statins compared with subjects taking cardiovascular medications other than statins, after adjusting for covariates associated with dementia or Parkinson's disease. RESULTS: We observed that simvastatin is associated with a significant reduction in the incidence of dementia in subjects > or =65 years, using any of three models. The first model incorporated adjustment for age, the second model included adjusted for three known risk factors for dementia, hypertension, cardiovascular disease or diabetes, and the third model incorporated adjustment for the Charlson index, which is an index that provides a broad assessment of chronic disease. Data were obtained for over 700,000 subjects taking simvastatin and over 50,000 subjects taking atorvastatin who were aged >64 years. Using model 3, the hazard ratio for incident dementia for simvastatin and atorvastatin are 0.46 (CI 0.44-0.48, p < 0.0001) and 0.91 (CI 0.80-1.02, p = 0.11), respectively. Lovastatin was not associated with a reduction in the incidence of dementia. Simvastatin also exhibited a reduced hazard ratio for newly acquired Parkinson's disease (HR 0.51, CI 0.4-0.55, p < 0.0001). CONCLUSION: Simvastatin is associated with a strong reduction in the incidence of dementia and Parkinson's disease, whereas atorvastatin is associated with a modest reduction in incident dementia and Parkinson's disease, which shows only a trend towards significance.
