Renal outcomes of simultaneous liver-kidney transplantation compared to liver transplant alone for candidates with renal dysfunction.

It is unclear whether a concomitant kidney transplant grants survival benefit to liver transplant (LT) candidates with renal dysfunction (RD). We retrospectively studied LT candidates without RD (n = 714) and LT candidates with RD who underwent either liver transplant alone (RD-LTA; n = 103) or simultaneous liver-kidney transplant (RD-SLKT; n = 68). RD was defined as renal replacement therapy (RRT) requirement or modification of diet in renal disease (MDRD)-glomerular filtration rate (GFR) <25 mL/min/1.73 m(2) . RD-LTAs had worse one-yr post-transplant survival compared to RD-SLKTs (79.6% vs. 91.2%, p = 0.05). However, RD-LTA recipients more often had hepatitis C (60.2% vs. 41.2%, p = 0.004) and more severe liver disease (MELD 37.9 ± 8.1 vs. 32.7 ± 9.1, p = 0.0001). Twenty RD-LTA recipients died in the first post-transplant year. Evaluation of the cause and timing of death relative to native renal recovery revealed that only four RD-LTA recipients might have derived survival benefit from RD-SLKT. Overall, 87% of RD-LTA patients recovered renal function within one month of transplant. One yr after RD-LTA or RD-SLKT, serum creatinine (1.5 ± 1.2 mg/dL vs. 1.4 ± 0.5 mg/dL, p = 0.63) and prevalence of stage 4 or 5 chronic kidney disease (CKD; 5.9% vs. 6.8%, p = 0.11) were comparable. Our series provides little evidence that RD-SLKT would have yielded substantial short-term survival benefit to RD-LTA recipients.

Health-Related Quality of Life in Patients with MPS II.

Mucopolysaccharidosis type II (MPS II), also known as Hunter syndrome, is a chronic and progressive X-linked lysosomal disease that mainly affects males. The National MPS Society (2013) reports that MPS II affects 1 in 100,000 to 1 in 150,000 males worldwide. Two distinct forms of the disease are based on age of onset and clinical course: attenuated and severe. MPS II affects many organ systems including the nervous, cardiovascular, gastrointestinal and respiratory systems. Clinical manifestations can include progressive hearing loss, mental impairment, and enlarged liver and spleen. This study focuses on the health-related quality of life of individuals (HRQOL) with MPS II as measured by the parent and self-report versions of the Pediatric Quality of Life Inventory (PedsQL™). Both parents of patients with MPS II as well as patients themselves reported lower scores on all domains of the PedsQL™ (physical, emotional, social and school functioning) indicating that children with MPS II have an overall lower HRQOL when compared to a healthy sample. When compared with patients with other chronic illnesses (cancer, MSUD, galactosemia,), the MPS II sample had significantly lower scores on a number of PedsQL™ scales, suggesting an overall lower HRQOL. No significant relationships were found using scores from parent or self report PedsQL™ measures and length of time on ERT.

NIH EXAMINER: conceptualization and development of an executive function battery.

Executive functioning is widely targeted when human cognition is assessed, but there is little consensus on how it should be operationalized and measured. Recognizing the difficulties associated with establishing standard operational definitions of executive functioning, the National Institute of Neurological Disorders and Stroke entered into a contract with the University of California-San Francisco to develop psychometrically robust executive measurement tools that would be accepted by the neurology clinical trials and clinical research communities. This effort, entitled Executive Abilities: Measures and Instruments for Neurobehavioral Evaluation and Research (EXAMINER), resulted in a series of tasks targeting working memory, inhibition, set shifting, fluency, insight, planning, social cognition and behavior. We describe battery conceptualization and development, data collection, scale construction based on item response theory, and lay the foundation for studying the battery's utility and validity for specific assessment and research goals.

Type 2 diabetes impairs annulus fibrosus fiber deformation and rotation under disc compression in the University of California Davis type 2 diabetes mellitus (UCD-T2DM) rat model.

Understanding the biomechanical behavior of the intervertebral disc is crucial for studying disease mechanisms and developing tissue engineering strategies for managing disc degeneration. We used synchrotron small-angle X-ray scattering to investigate how changes to collagen behavior contribute to alterations in the disc's ability to resist compression. Coccygeal motion segments from 6-month-old lean Sprague-Dawley rats ( n=7) and diabetic obese University of California Davis type 2 diabetes mellitus (UCD-T2DM) rats ( n=6, diabetic for 68±7 days) were compressed during simultaneous synchrotron scanning to measure collagen strain at the nanoscale (beamline 7.3.3 of the Advanced Light Source). After compression, the annulus fibrosus was assayed for nonenzymatic cross-links. In discs from lean rats, resistance to compression involved two main energy-dissipation mechanisms at the nanoscale: (1) rotation of the two groups of collagen fibrils forming the annulus fibrosus and (2) straightening (uncrimping) and stretching of the collagen fibrils. In discs from diabetic rats, both mechanisms were significantly impaired. Specifically, diabetes reduced fibril rotation by 31% and reduced collagen fibril strain by 30% (compared to lean discs). The stiffening of collagen fibrils in the discs from diabetic rats was consistent with a 31% higher concentration of nonenzymatic cross-links and with evidence of earlier onset plastic deformations such as fibril sliding and fibril-matrix delamination. These findings suggest that fibril reorientation, stretching, and straightening are key deformation mechanisms that facilitate whole-disc compression, and that type 2 diabetes impairs these efficient and low-energy elastic deformation mechanisms, thereby altering whole-disc behavior and inducing the earlier onset of plastic deformation.

The New York policy on smoking in addiction treatment: findings after 1 year.

OBJECTIVES: We assessed changes in smoking prevalence and other measures associated with the July 2008 New York Office of Alcoholism and Substance Abuse Services tobacco policy, which required that all publicly funded addiction treatment programs implement smoke-free grounds, have "no evidence" of smoking among staff, and make tobacco dependence treatment available for all clients. METHODS: In a random sample of 10 programs, staff and clients were surveyed before the policy and 1 year later. Measures included tobacco-related knowledge, attitudes, and practices used by counselors and received by clients. RESULTS: Client smoking decreased from 69.4% to 62.8% (P = .044). However, response to the policy differed by program type. Outpatient programs showed no significant changes on any of the staff and client survey measures. In methadone programs, staff use of tobacco-related practices increased (P < .01), client attitudes toward tobacco treatment grew more positive (P < .05), and clients received more tobacco-related services (P < .05). Residential clients were more likely to report having quit smoking after policy implementation (odds ratio = 4.7; 95% confidence interval = 1.53, 14.19), but they reported less favorable attitudes toward tobacco treatment (P < .001) and received fewer tobacco-related services from their program (P < .001) or their counselor (P < .001). CONCLUSIONS: If supported by additional research, the New York policy may offer a model that addiction treatment systems can use to address smoking in a population where it has been prevalent and intractable. Additional intervention or policy supports may be needed in residential programs, which face greater challenges to implementing tobacco-free grounds.

The frontal-anatomic specificity of design fluency repetitions and their diagnostic relevance for behavioral variant frontotemporal dementia.

On tests of design fluency, an examinee draws as many different designs as possible in a specified time limit while avoiding repetition. The neuroanatomical substrates and diagnostic group differences of design fluency repetition errors and total correct scores were examined in 110 individuals diagnosed with dementia, 53 with mild cognitive impairment (MCI), and 37 neurologically healthy controls. The errors correlated significantly with volumes in the right and left orbitofrontal cortex (OFC), the right and left superior frontal gyrus, the right inferior frontal gyrus, and the right striatum, but did not correlate with volumes in any parietal or temporal lobe regions. Regression analyses indicated that the lateral OFC may be particularly crucial for preventing these errors, even after excluding patients with behavioral variant frontotemporal dementia (bvFTD) from the analysis. Total correct correlated more diffusely with volumes in the right and left frontal and parietal cortex, the right temporal cortex, and the right striatum and thalamus. Patients diagnosed with bvFTD made significantly more repetition errors than patients diagnosed with MCI, Alzheimer's disease, semantic dementia, progressive supranuclear palsy, or corticobasal syndrome. In contrast, total correct design scores did not differentiate the dementia patients. These results highlight the frontal-anatomic specificity of design fluency repetitions. In addition, the results indicate that the propensity to make these errors supports the diagnosis of bvFTD. (JINS, 2012, 18, 1-11).

Smoking prevalence in addiction treatment: a review.

INTRODUCTION: This review explores whether smoking prevalence in addiction treatment samples exceeds that shown in epidemiological data for persons with alcohol or other drug use disorders and whether smoking may have decreased over time in the addiction treatment population as it has done in the general population. METHODS: English language papers published between 1987 and 2009 were searched electronically. Forty papers reporting smoking prevalence for addiction treatment samples in the United States were identified, and key predictor variables were abstracted. Random logistic models were used to assess relationships between each individual predictor (year, treatment modality, primary drug treated, government status, and public/private funding status) and smoking prevalence. RESULTS: The lowest smoking prevalence aggregated for studies reported in any single year was 65%, well above epidemiological estimates reported among those with alcohol use and drug use disorders. The odds of smoking were higher in methadone maintenance programs (odds ratio [OR] = 2.25, CI = 1.08, 4.68) as compared with outpatient programs. No other variables in the model were significant. Reanalysis omitting recent studies that may represent outliers or confounding with type of treatment showed a small but significant decrease in smoking over time (OR = 0.9891, CI = 0.9888, 0.9893). CONCLUSIONS: The very high smoking rates reported in addiction treatment samples warrant significant, organized, and systemic response from addiction treatment systems, from agencies that fund and regulate those systems, and from agencies concerned with tobacco control.

Impact of learning HIV status on contraceptive use in the MIRA trial.

BACKGROUND AND METHODOLOGY: We examined the effect of becoming HIV-positive on contraceptive practices in a Phase III randomised controlled trial of the diaphragm for HIV prevention. We coded self-reported contraceptive use into seven categories of methods in order of effectiveness. We compared the proportion using each category of contraception at baseline and last visit between women who did and did not become HIV-positive. We compared changes in the proportion using each category of contraception from baseline to last visit and calculated the percentage of women that moved to a more or less effective method category or stayed the same. We examined immediate and long-term changes in contraceptive use category after learning HIV-positive status. RESULTS: A total of 4645 women remained HIV-negative and 309 became HIV-positive. The proportion using each category of contraception was similar between groups at baseline and last visit. In both groups approximately one-fifth changed to a less effective method category between baseline and last visit. Few women reported using long-acting methods. Among HIV-positive women, shorter-term changes in the proportion using each category of contraception were similar to longer-term changes, though somewhat more women were using a method in the same category 3 months after seroconversion. DISCUSSION AND CONCLUSIONS: Learning about HIV-positive status did not appear to significantly change patterns of use of effective contraceptives or the probability of switching to a more or less effective method. Information about, and access to, long-acting methods should receive more attention and be a routine part of family planning programmes and prevention trials.

A Randomized Trial of Probation Case Management for Drug-Involved Women Offenders.

This paper reports findings from a clinical trial of a probation case management (PCM) intervention for drug-involved women offenders. Participants were randomly assigned to either PCM (n=92) or standard probation (n=91), and followed for 12 months using measures of substance abuse, psychiatric symptoms, social support and service utilization. Arrest data were collected from administrative datasets. The sample (N=183) included mostly African American (57%) and White (20%) women, with a mean age of 34.7 (SD = 9.2) and mean education of 11.6 years (SD = 2.1). Cocaine and heroin were the most frequently reported drugs of abuse, 86% reported prior history of incarceration, and 74% had children. Women assigned to both PCM and standard probation showed change over time in the direction of clinical improvement on 7 of 10 outcomes measured. However, changes observed for the PCM group were no different than those observed for the standard probation group. Higher levels of case management, drug abuse treatment, and probationary supervision may be required to achieve improved outcomes in this population.

Presentation and disease course in early- compared to later-onset pediatric Crohn's disease.

BACKGROUND: The relationship between the age at diagnosis and disease course is poorly defined in children with Crohn's disease (CD). We examined the presentation and course of disease in patients 0-5 compared to 6-17 yr of age at diagnosis. METHODS: We analyzed uniform data from 989 consecutive CD patients collected between January 2000 and November 2003, and stored in the Pediatric IBD Consortium Registry. The statistical tests account for the length of follow-up of each patient. RESULTS: In total, 98 patients (9.9%) were of 0-5 yr of age at diagnosis. The mean follow-up time was 5.6 +/- 5.0 yr in the younger group and 3.3 +/- 2.8 yr in the older group (P < 0.001). Race/ethnicity differed by the age group (P= 0.015); a larger proportion of the younger group was Asian/Pacific Islander or Hispanic, and a larger proportion of the older group was African American. The initial classification as ulcerative colitis or indeterminate colitis was more common among the 0-5 yr of age group (P < 0.001). The 6-17 yr of age patients presented with more abdominal pain (P < 0.001), weight loss (P= 0.001), or fever (P= 0.07), while the 0-5 yr of age patients presented with more rectal bleeding (P= 0.008). The 6-17 yr of age patients were more likely to be treated with antibiotics (P < 0.001), 6-mercaptopurine/azathioprine (P < 0.001), infliximab (P= 0.001), or corticosteroids (P= 0.0006). The 6-17 yr of age patients had a higher cumulative incidence of treatment with 5-aminosalicylates (P= 0.009) or methotrexate (P= 0.04). The risk for developing an abscess (P= 0.001), a fistula (P= 0.02), a stricture (P= 0.05), or a perianal fissure (P= 0.06) was greater in the 6-17 yr of age patients. CONCLUSIONS: The 6-17 yr of age patients with CD appear to have a more complicated disease course compared to 0-5 yr of age children. The 0-5 yr of age group may represent a unique disease phenotype and benefit from different approaches to management. Long-term prospective studies are required to validate these findings.

Topographic comparison of the visual function on multifocal visual evoked potentials with optic nerve structure on heidelberg retinal tomography.

PURPOSE: The authors' objective was to compare the visual field obtained using multifocal visual evoked potential (mfVEP) testing with the optic nerve parameters of Heidelberg retinal tomography (HRT; Heidelberg Engineering, Heidelberg, Germany; software version 2.01) in primary open-angle glaucoma (POAG) patients and normal controls and to determine which parameters correlate with visual function. DESIGN: Cross-sectional study. PARTICIPANTS: Eighty-one eyes of 42 adult POAG patients and normal controls between the ages of 40 and 80 years, of which 35 patients (67 eyes; mean age+/-standard deviation [SD], 68+/-10 years) had POAG, and 7 individuals who served as normal controls (14 eyes; mean age+/-SD, 61+/-10 years) were included. METHODS: A monocular mfVEP test, the AccuMap (Opera software version 2.0; ObjectiVision Pty. Ltd., Sydney, Australia), with a 58-sector pattern-reversal dart board array was recorded in both eyes per patient. These patients underwent the HRT 2 and mfVEP tests within 3 months of each other. MAIN OUTCOME MEASURES: Amplitudes in the superior hemisphere of the mfVEP trace were compared with the HRT parameters in the inferior hemisphere of the HRT and vice versa using mixed effects regression models. RESULTS: Amplitudes on the superior hemisphere of the mfVEP recordings showed a significant direct correlation with rim-to-disc area ratio (P = 0.0037), rim volume (P = 0.0421), and mean retinal nerve fiber layer (RNFL) thickness (P = 0.0016) and a significant inverse correlation with cup area (P = 0.0009) and cup-to-disc area ratio (P = 0.0037) in the inferior hemisphere of the HRT results. Amplitudes on the inferior hemisphere showed a significant direct correlation with rim-to-disc area ratio (P = 0.036) and a significant inverse correlation with cup area (P = 0.0007), cup-to-disc area ratio (P = 0.036), cup volume (P<0.0001), and mean cup depth (P = 0.0012) in the superior hemisphere of the HRT results. CONCLUSIONS: Results from mfVEP and HRT showed correlation between visual function and optic nerve structure.

Design, power, and interpretation of studies in the standard murine model of ALS.

Identification of SOD1 as the mutated protein in a significant subset of familial amyotrophic lateral sclerosis (FALS) cases has led to the generation of transgenic rodent models of autosomal dominant SOD1 FALS. Mice carrying 23 copies of the human SOD1(G93A) transgene are considered the standard model for FALS and ALS therapeutic studies. To date, there have been at least 50 publications describing therapeutic agents that extend the lifespan of this mouse. However, no therapeutic agent besides riluzole has shown corresponding clinical efficacy. We used computer modeling and statistical analysis of 5429 SOD1(G93A) mice from our efficacy studies to quantify the impact of several critical confounding biological variables that must be appreciated and should be controlled for when designing and interpreting efficacy studies. Having identified the most critical of these biological variables, we subsequently instituted parameters for optimal study design in the SOD1(G93A) mouse model. We retested several compounds reported in major animal studies (minocycline, creatine, celecoxib, sodium phenylbutyrate, ceftriaxone, WHI-P131, thalidomide, and riluzole) using this optimal study design and found no survival benefit in the SOD1(G93A) mouse for any compounds (including riluzole) administered by their previously reported routes and doses. The presence of these uncontrolled confounding variables in the screening system, and the failure of these several drugs to demonstrate efficacy in adequately designed and powered repeat studies, leads us to conclude that the majority of published effects are most likely measurements of noise in the distribution of survival means as opposed to actual drug effect. We recommend a minimum study design for this mouse model to best address and manage this inherent noise and to facilitate more significant and reproducible results among all laboratories employing the SOD1(G93A) mouse.

House staff team workload and organization effects on patient outcomes in an academic general internal medicine inpatient service.

BACKGROUND: House staff work-hour regulations have required residency programs to reengineer inpatient services. However, few data describe how house staff workload on a patient's day of admission or on subsequent hospital days influences patient outcomes. METHODS: Retrospective cohort analysis of 5742 adults admitted to an academic general medical service between July 1, 1998, and June 30, 2001. RESULTS: After multivariate risk adjustment for patient severity and other structural factors, we found that 2 different measures of house staff workload significantly affected patient outcomes. House staff workload increases on the day of admission, defined as each additional team admission on a patient's admission day, increased length of stay (difference, 3.09%; 95% confidence interval [CI], 2.22%-3.96%), total costs (difference, 2.31%; 95% CI, 1.29%-3.33%), and risk of inpatient mortality (odds ratio, 1.09; 95% CI, 1.02-1.15). Patients had an even higher mortality risk when more than 9 patients were admitted to their team on their admission day. In contrast, house staff workload increases during the patient's entire stay, defined as every additional patient added to the team average census, reduced length of stay (difference, -5.30%; 95% CI, -4.54% to -6.07%) and total costs (difference, -5.11%; 95% CI, -4.20% to -6.00%). Reductions in length of stay and costs were most striking when the team average census exceeded 15 patients. CONCLUSIONS: Our findings suggest that higher house staff workload on admitting days-when fewer backup resources are available-increases resource use and may increase inpatient mortality. Conversely, a higher average team census was associated with reduced resource use, perhaps reflecting service-level adaptations to workload. Future studies should confirm these findings in larger trials.

Repeatability of the multifocal visual evoked potentials in a clinical glaucoma setting.

BACKGROUND: To determine the reproducibility of the multifocal visual evoked potentials (mfVEP) test results in a clinical glaucoma setting, and the factors that affect variability. METHODS: This was an observational case series study. The monocular mfVEP test, having a 58-sector, pattern-reversal dartboard array, was performed twice within 4 weeks in both eyes of 29 adult open-angle glaucoma (OAG) patients and suspects, using AccuMap Opera Software (ObjectiVision Pty Ltd, Sydney, Australia). The AccuMap severity index (ASI), the mean amplitude, and the individual amplitudes in each sector were compared between the 2 tests using intraclass correlations (ICCs). The effects of the severity of mfVEP field defects and signal-to-noise ratio (SNR) on the reproducibility of these variables were determined using the McNemar test and the Spearman rank correlation, respectively. RESULTS: The average ICCs of the ASI and amplitudes in the 2 tests were 0.84 and 0.87, respectively. Two sectors in the right eye and 6 in the left eye had significant differences between the 2 tests (Wilcoxon signed-rank p < 0.05). Larger differences were observed in patients having lower SNR (Spearman p = 0.022). Forty-six of the 58 eyes stayed within the same diagnosis category on repeating the test (i.e., within normal limits or outside normal limits). INTERPRETATION: Although there were some isolated examples of clinically significant differences on repeating the mfVEP test in our patients, our results suggest overall good repeat reliability. The variability of the test was higher in patients having high noise levels during the test.

Community-acquired necrotizing soft tissue infections: a review of 122 cases presenting to a single emergency department over 12 years.

PURPOSE: To characterize the Emergency Department (ED) presentation of necrotizing soft tissue infections (NSTI) and identify severity markers. PROCEDURES: Retrospective chart review of pathologically diagnosed NSTIs presenting to an urban ED from 1990-2001. Cases were identified from a surgical database, ICD-9 search and prospectively. Five Emergency Physicians (EPs) abstracted data using a standardized form. Severe NSTI was defined by any of the following: death, amputation, intensive care unit (ICU) stay >24 h, >300 cm(2) debrided. Severe and non-severe cases were compared using chi-square, Fisher's exact, and multivariate logistic regression testing. FINDINGS: The 122 cases were characterized by: injection drug use, 80%; fever, 44%; systolic blood pressure (BP) <100 mm Hg, 21%; white blood cell count (WBC) >20 x 10(9)/L, 43%; median time to operation, 8.4 h; mortality, 16%. The managing EP suspected NSTI in 59%. A systolic BP <100 mm Hg, BUN >18 mg/dL, radiographic soft tissue gas, admission to a non-surgical service and clostridial species were independently associated with severe NSTI. CONCLUSIONS: Pathologically defined NSTIs have a wide spectrum of ED presentations and early diagnosis remains difficult.

Low rates of antiretroviral therapy among HIV-infected patients with chronic kidney disease.

BACKGROUND: It is unknown whether chronic kidney disease (CKD) influences receipt of highly active antiretroviral therapy (HAART) among patients with the human immunodeficiency virus (HIV) and whether prescription practices contribute to excess mortality. METHODS: We conducted a retrospective observational study involving HIV-infected patients with established indications for HAART and an outpatient serum creatinine level measured in the Veterans Affairs health care system. Patients were followed up for the outcomes of HAART exposure (percentage of follow-up time treated with HAART), inadequate dose adjustment of renally eliminated antiretroviral medications, and time to death. RESULTS: A total of 1041 patients (8.5%) had CKD, defined as an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m(2). Compared with patients with an eGFR >or=60 mL/min/1.73 m(2), HAART exposure was 14% less (95% confidence interval [CI], 2%-24% less), 24% less (95% CI, 4% more to 45% less), 64% less (95% CI, 38%-79% less), and 49% less (95% CI, 32%-61% less) in patients who had an eGFR of 30-59 mL/min/1.73 m(2), 15-29 mL/min/1.73 m(2), and <15 mL/min/1.73 m(2) (and were not receiving dialysis) and in patients receiving long-term dialysis, respectively. At study entry, 15.4% of patients with CKD received HAART unadjusted for the level of renal function. The adjusted hazard ratio for death was 1.36 (95% CI, 1.08-1.72) for patients with an eGFR of 30-59 mL/min/1.73 m(2), 2.17 (95% CI, 1.43-3.27) for patients with an eGFR of 15-29 mL/min/1.73 m(2), 5.97 (95% CI, 3.18-11.19) for patients with an eGFR <15 mL/min/1.73 m(2), and 1.92 (95% CI, 1.30-2.82) for dialysis-dependent patients. Underexposure and inadequate dose adjustment of HAART were associated with 22.5%-35.5% of the excess mortality found among patients with different levels of CKD. CONCLUSIONS: Underexposure and inadequate dose adjustment of HAART may contribute to excess mortality among HIV-infected patients with CKD.

Moderate alcohol use and reduced mortality risk: systematic error in prospective studies and new hypotheses.

We have provided recent evidence suggesting that a systematic error may be operating in prospective epidemiological mortality studies that have reported "light" or "moderate" regular use of alcohol to be "protective" against coronary heart disease. Using meta-analysis as a research tool, a hypothesis first suggested by Shaper and colleagues was tested. Shaper et al suggested that people decrease their alcohol consumption as they age and become ill or frail or increase use of medications, some people abstaining from alcohol altogether. If these people are included in the abstainer category in prospective studies, it is reasoned that it is not the absence of alcohol elevating their risk for coronary heart disease (CHD) but, rather, their ill health. Our meta-analytic results indicate that the few studies without this error (i.e., those that did not contaminate the abstainer category with occasional or former drinkers) show abstainers and "light" or "moderate" drinkers to be at equal risk for all-cause and CHD mortality. We explore the history of this hypothesis, examine challenges to our meta-analysis, and discuss options for future research.

Symptom management with massage and acupuncture in postoperative cancer patients: a randomized controlled trial.

The level of evidence for the use of acupuncture and massage for the management of perioperative symptoms in cancer patients is encouraging but inconclusive. We conducted a randomized, controlled trial assessing the effect of massage and acupuncture added to usual care vs. usual care alone in postoperative cancer patients. Cancer patients undergoing surgery were randomly assigned to receive either massage and acupuncture on postoperative Days 1 and 2 in addition to usual care, or usual care alone, and were followed over three days. Patients' pain, nausea, vomiting, and mood were assessed at four time points. Data on health care utilization were collected. Analyses were done by mixed-effects regression analyses for repeated measures. One hundred fifty of 180 consecutively approached cancer patients were eligible and consented before surgery. Twelve patients rescheduled or declined after surgery, and 138 patients were randomly assigned in a 2:1 scheme to receive massage and acupuncture (n=93) or to receive usual care only (n=45). Participants in the intervention group experienced a decrease of 1.4 points on a 0-10 pain scale, compared to 0.6 in the control group (P=0.038), and a decrease in depressive mood of 0.4 (on a scale of 1-5) compared to +/-0 in the control group (P=0.003). Providing massage and acupuncture in addition to usual care resulted in decreased pain and depressive mood among postoperative cancer patients when compared with usual care alone. These findings merit independent confirmation using larger sample sizes and attention control.

Does treated systemic hypertension affect progression of optic nerve damage in glaucoma suspects?

PURPOSE: To evaluate whether treatment of systemic hypertension has an effect on progression of optic nerve parameters in glaucoma suspects using confocal scanning laser ophthalmoscopy. METHODS: Two hundred eyes of 103 glaucoma suspect patients were included in this retrospective cohort study. Thirty-one patients (of whom 59 eyes were included in the study) had systemic hypertension under treatment (based on medical history). The remaining 72 age-matched normotensive controls (of whom 141 eyes were included in the study) were not on blood-pressure-lowering medications. Each patient had a follow-up period of at least 4 years with a minimum of four Heidelberg retinal tomograph tests (one baseline and three follow-up scans). The slopes of progression of optic nerve head parameters with time were studied and compared between these two groups using mixed effects regression models. RESULTS: Patients with systemic hypertension showed a statistically significant increase in cup area (slope 0.2, p = 0.03), cup-to-disk area ratio (slope 0.01, p = 0.007), and decrease in rim area (slope -0.4, p = 0.03), rim-to-disk area ratio (slope -0.01, p = 0.005), and global Retinal Nerve Fiber Layer (RNFL) thickness (p = 0.008) with time. The differences in slopes of progression of many parameters between hypertensives and normotensives were statistically significant. CONCLUSIONS: Systemic hypertension treated with hypotensive medications may be a risk factor for increased progression of optic nerve parameters in glaucoma suspects compared with age-matched normotensive subjects.

Factor analysis of the Alcohol and Drug Confrontation Scale (ADCS).

The Alcohol and Drug Confrontation Scale (ADCS) is a 72-item instrument that defines confrontation as an individual being told "bad things" might happen if they do not make changes to address alcohol or drug problems or maintain sobriety. Preliminary assessment of the ADCS using substance abusers entering SLH's revealed: (1) scale items were frequently endorsed; (2) confrontation was often experienced as accurate and helpful; and (3) confronters' statements were viewed supportive and accurate. This study reports the results of a factor analysis on a larger sample 179 participants using baseline and 6 month follow-up data. Results yielded a clear two factor solution: (1) Internal Support (alpha=0.80) and (2) External Intensity (alpha=0.63). The two factors accounted for 58% of the variance. The ADCS offers a fresh and broader view of confrontation that can be reliably measured.
