Prognostic factors during outpatient treatment for alcohol dependence: cohort study with 6 months of treatment follow-up.

To identify prognostic factors to outpatient alcohol treatment on admission as well as during the treatment period.



A cohort study of n = 209 alcoholic patients (DSM-IV) during 6 months of outpatient treatment. Eight medical doctors from two hospitals were involved. Co-responsible participation in treatment was a necessary condition. At admission, we documented socio demographic factors, use of other drugs and severity of alcohol consumption. During the 6 months, we observed medication for prevention of alcohol relapse [disulfiram (DIS), acamprosate], number of sessions with the doctor, number of phases of the consultation and medication for depression. Primary outcome variables were time to first heavy relapse and abstinence of heavy alcohol consumption. These were measured with Timeline Followback. Five or more alcohol units of 10 g in one relapse day were considered heavy relapse.



The patients were 84% males, with 41 years median age; the median alcohol consumption was 192 g per day with a median duration of 13 years of heavy consumption. The median education was 6 years with 61% of the patients from lower socio-economic levels. The Kaplan-Meier heavy relapse rate at 6 months was 23%. On admission to treatment, female gender, lower socio-economic levels, cocaine use, >20 years of consumption, gamma glutamyl transferase values above normal and five or more alcohol-related problems on the Alcohol-Related Problem Questionnaire predicted worse outcomes. Having a full-time job and shorter abstinence time before treatment (until 7 days) predicted better outcomes. During the 6 months, we found that DIS for <120 days was a prognostic factor of worse outcomes. DIS for at least 120 days, >50% of adherence to consultations and more than two phases on each consultation predicted better outcomes. The combined sensitivity and specificity for DIS for at least 120 days, >50% of adherence to consultations and more than two phases on consultation regarding abstinence from heavy relapse were respectively 100 and 71%.



During 6 months of outpatient treatment, longer adherence to DIS and consultations as well as more phases in a consultation involving necessarily a co-responsible predict a good outcome independently of the patient features at admission.
Safety and tolerability of a modified filter-type device for leukocytapheresis using ACD-A as anticoagulant in patients with mild to moderately active ulcerative colitis. Results of a pilot study.

Cellsorba™ is a medical device for leukocytapheresis (LCAP) treatment of ulcerative colitis (UC). Cellsorba™ EX Global type has been developed from Cellsorba E for intended use with ACD-A as anticoagulant. We evaluated safety and efficacy of the modified Cellsorba using ACD-A in a pilot trial comprising patients with active UC, despite receiving 5-ASA. A total of 10 LCAP treatments/patients were administered. Safety assessment focused on clinical signs and symptoms, hematological variables, as well as levels of bradykinin and IL-6. Efficacy was determined using the Mayo clinical/endoscopic scoring index as well histological assessment of biopsies. Additional aim was to evaluate the impact of apheresis system lines and filter on selected regulatory molecules. All six subjects completed the trial without any serious adverse events. WBC, platelet counts, and levels of bradykinin and IL-6 were not significantly affected. The median Mayo score decreased from 8.0 to 3.5 at week 8 (and to 2 at week 16 for the responders). Four patients were responders, of whom two patients went into remission. Median histological scores decreased from 3.5 to 2.0 in these four patients. Concentration of LL-37 increased within the apheresis system lines. LCAP with Cellsorba EX using ACD-A as anticoagulant was found to be a safe and well-tolerated procedure in patients with active UC. The positive impact on efficacy parameters merits further evaluation in a controlled fashion.
Patients with adenosine deaminase deficiency surviving after hematopoietic stem cell transplantation are at high risk of CNS complications.

Adenosine deaminase (ADA) deficiency is a systemic metabolic disease that causes an autosomal recessive variant of severe combined immunodeficiency (SCID) and less consistently other complications including neurologic abnormalities. Hematopoietic stem cell transplantation (HSCT) is able to correct the immunodeficiency, whereas control of nonimmunologic complications has not been extensively explored. We applied HSCT in 15 ADA-deficient patients consecutively treated at our institutions since 1982 and analyzed long-term outcome. Seven patients received transplants without conditioning from HLA-matched family donors (MFDs); the other 8 patients received conditioning and were given transplants either from HLA-mismatched family donors (MMFDs; n = 6) or from matched unrelated donors (MUDs; n = 2). At a mean follow-up period of 12 years (range, 4-22 years), 12 patients are alive with stable and complete immune reconstitution (7 of 7 after MFD, 4 of 6 after MMFD, and 1 of 2 after MUD transplantation). Six of 12 surviving patients show marked neurologic abnormalities, which include mental retardation, motor dysfunction, and sensorineural hearing deficit. We were unable to identify disease or transplantation-related factors correlating with this divergent neurologic outcome. The high rate of neurologic abnormalities observed in long-term surviving patients with ADA deficiency indicates that HSCT commonly fails to control CNS complications in this metabolic disease.
Accuracy of Heart Disease Prevalence Estimated from Claims Data Compared With an Electronic Health Record

We developed a decision support tool that can guide the development of heart disease prevention programs to focus on the interventions that have the most potential to benefit populations. To use it, however, users need to know the prevalence of heart disease in the population that they wish to help. We sought to determine the accuracy with which the prevalence of heart disease can be estimated from health care claims data.



We compared estimates of disease prevalence based on insurance claims to estimates derived from manual health records in a stratified random sample of 480 patients aged 30 years or older who were enrolled at any time from August 1, 2007, through July 31, 2008 (N = 474,089) in HealthPartners insurance and had a HealthPartners Medical Group electronic record. We compared randomly selected development and validation samples to a subsample that was also enrolled on August 1, 2005 (n = 272,348). We also compared the records of patients who had a gap in enrollment of more than 31 days with those who did not, and compared patients who had no visits, only 1 visit, or 2 or more visits more than 31 days apart for heart disease.



Agreement between claims data and manual review was best in both the development and the validation samples (Cohen's κ, 0.92, 95% confidence interval [CI], 0.87-0.97; and Cohen's κ, 0.94, 95% CI, 0.89-0.98, respectively) when patients with only 1 visit were considered to have heart disease.



In this population, prevalence of heart disease can be estimated from claims data with acceptable accuracy.
Efficacy of glimepiride on insulin resistance, adipocytokines, and atherosclerosis.

Plasma adiponectin levels increase after the administration of glimepiride. This unique effects would also be expected to improve other adipocytokines and have anti-atherosclerotic action in patients with metabolic syndrome.



Thirty-four patients with type 2 diabetes mellitus who were administrated glibenclamide were randomly divided into two groups. In 20 patients glibenclamide was changed to glimepiride (GP group), and the administration of glibenclamide (GB group) was continued in 14 patients. Twelve patients receiving insulin therapy (INS group) were enrolled for comparison. The levels of plasma adiponectin, high sensitive-CRP, TNF-alpha, interleukin-6, homeostasis model assessment-insulin resistance (HOMA-IR), brachial-ankle pulse wave velocity (baPWV) and augmentation index (AI) were measured before and 28 weeks after the therapy.



HOMA-IR in the GP group was significantly decreased compared to the GB group. Plasma adiponectin levels were significantly increased in the GP group but not in the other groups. TNF-alpha, interleukin-6 and high sensitive-CRP levels were significantly decreased in the GP group, but not in the other groups. The baPWV and AI levels did not change in either the GB or the INS group, but were significantly decreased in the GP group.



Glimepiride appears to improve insulin resistance and atherosclerotic disorders.
Management and Outcome of Uveal Melanoma in a Single Tertiary Cancer Center in Jordan.

The aim of this study was evaluate the features and outcome of management of uveal melanoma in King Hussein Cancer Center as an example of a referral tertiary cancer center in the Middle East.



This was aetrospective, observational case series of 46 eyes of 46 patients with uveal melanoma. Data collection required access to medical records, radiology and pathology reports, and laboratory results. The main outcome measures included age at diagnosis, tumor location and dimensions, TNM stage, treatment modality, visual outcome, metastasis, and mortality.



There was slight female preference, and the median age at diagnosis was 45 years. Eighteen (39%) eyes were treated by primary enucleation, and 28 (61%) eyes were treated by I-125 radioactive plaque. The melanoma was in the choroid in 40 (87%) eyes and in the ciliary body in 6 (13%) eyes, with no single tumor in the iris. According to the 7th edition of the American Joint Committee on Cancer staging system (UICC/AJCC); 8 (17%) were T1, 17 (36%) were T2, 16 (35%) were T3, and 5 (11%) were T4. One (2%) patient showed lymph node metastasis (N1), and 6 (13%) patients showed distant metastasis (M1). Pathologically, 2 (10%) of the enucleated eyes were spindle cell type, 4 (20%) were epithelioid cell type, and 14 (70%) were mixed type. Extrascleral extension was seen in three (15%) eyes, and optic nerve invasion in two (10%) eyes. After brachytherapy, 26 (93%) eyes were salvaged, and 2 eyes were consecutively enucleated; one for tumor recurrence, and one for uncontrolled painful neovascular glaucoma. The eye salvage rate post plaque was 93% (26/28), and the visual acuity for the salvaged eyes was equal or better than 0.5 in 11 (42%) eyes, 0.1-0.4 in 5 (19%) eyes, and less than 0.1 in 10 (38%) eyes.



The incidence of uveal melanomas in our region is low compared to that in the West with a younger age at presentation. Candidate tumors for radioactive plaque therapy were successfully controlled in 93% of cases.
Cholesterol lowering and inhibition of sterol absorption by Lactobacillus reuteri NCIMB 30242: a randomized controlled trial

The percentage of hypercholesterolemic individuals not reaching their LDL-cholesterol (LDL-C) goal remains high and additional therapeutic strategies should be evaluated. The objective of this study was to evaluate the cholesterol-lowering efficacy and mechanism of action of bile salt hydrolase-active Lactobacillus reuteri NCIMB 30242 capsules in hypercholesterolemic adults.A total of 127 subjects completed a randomized, double-blind, placebo-controlled, parallel-arm, multicenter study. Subjects were randomized to consume L. reuteri NCIMB 30242 capsules or placebo capsules over a 9-week intervention period. The primary outcome was LDL-C relative to placebo at the study end point.L. reuteri NCIMB 30242 capsules reduced LDL-C by 11.64% (P<0.001), total cholesterol by 9.14%, (P<0.001), non-HDL-cholesterol (non-HDL-C) by 11.30% (P<0.001) and apoB-100 by 8.41% (P=0.002) relative to placebo. The ratios of LDL-C/HDL-cholesterol (HDL-C) and apoB-100/apoA-1 were reduced by 13.39% (P=0.006) and 9.00% (P=0.026), respectively, relative to placebo. Triglycerides and HDL-C were unchanged. High-sensitivity C-reactive protein and fibrinogen were reduced by 1.05 mg/l (P=0.005) and 14.25% (P=0.004) relative to placebo, respectively. Mean plasma deconjugated bile acids were increased by 1.00 nmol/l (P=0.025) relative to placebo, whereas plasma campesterol, sitosterol and stigmasterol were decreased by 41.5%, 34.2% and 40.7%, respectively.The present results suggest that the deconjugation of intraluminal bile acids results in reduced absorption of non-cholesterol sterols and indicate that L. reuteri NCIMB 30242 capsules may be useful as an adjunctive therapy for treating hypercholesterolemia.
Short-cycle therapy in adolescents after continuous therapy with established viral suppression: the impact on viral load suppression.

This was a proof-of-principle study to evaluate the impact of short cycle therapy (SCT; 4 days on/3 days off) in adolescents and young adults with good viral suppression on a protease inhibitor-based antiretroviral regimen. Subjects were recruited by the Adolescent Trials Network for HIV/AIDS Interventions and the Pediatric AIDS Clinical Trials Group. Subjects were infected either through perinatal/early childhood transmission or later via risk behaviors. All subjects were required to have at least 6 months of documented viral suppression below 400 copies/ml plus a preentry value below 200 copies/ml and an entry CD4+ T cell count above 350 cells/mm3. Of the 32 subjects enrolled, 12 (37.5%) had confirmed viral load rebound >400 copies, with 18 subjects (56%) coming off for any reason. The majority of subjects resuppressed when placed back onto continuous therapy using the same agents. Although no difference was found in virologic rebound rates between the early and later transmission groups, those infected early in life had higher rates of coming off SCT for any reason. There was no impact of SCT on the CD4+ T cell counts in those who remained on study or those who came off SCT for any reason. Subjects demonstrated good adherence to the SCT regimen. This study suggests that further evaluation of SCT may be warranted in some groups of adolescents and young adults infected with HIV.
Serum Selenium Levels in Korean Hepatoma Patients

The aim of this study was to determine serum selenium (Se) levels during the development of liver disease as well as the possible Se supplementation benefits in liver disease patients. Serum was collected from 187 patients with liver diseases and 120 normal healthy people living in Seoul. The samples were collected at the Kangnam St. Mary’s Hospital College of Medicines, The Catholic University of Korea, in accordance with procedures approved by the Institutional Review Board of the Catholic University of Korea. Serum Se levels were quantified by inductively coupled plasma mass spectrometry and were compared between healthy and liver diseases patients. Se levels were 92.65 ± 32.50 μg/l in hepatitis infection, 92.33 ± 30.66 μg/l in hepatitis B virus infection and 96.41 ± 51.50 μg/l in hepatitis C virus infection, 96.42 ± 32.80 μg/l in cirrhosis, and 67.47 ± 14.30 μg/l in hepatoma patients. Findings were significantly lower in hepatitis and hepatoma as compared with the healthy participants (P < 0.001). The Se level of the healthy population was 108.38 ± 29.50, 119.37 ± 28.31 for males and 97.87 ± 26.99 μg/l for females. Our data shows the same parallelism between liver disease progression and decrease of Se levels except in the case of liver cirrhosis. And also, our study confirms the previous findings of significantly lower Se levels in Korean hepatoma patients. Se levels that decrease parallel to liver disease progression should be further integrated and analyzed with liver function blood biomarkers.
Evaluation of the total face mask for noninvasive ventilation to treat acute respiratory failure.

We hypothesized that the total face mask (TFM) would be perceived as more comfortable than a standard oronasal mask (ONM) by patients receiving noninvasive mechanical ventilation (NIV) therapy for acute respiratory failure (ARF) and would be quicker to apply by respiratory therapists.



Sixty patients presenting with ARF were randomized to receive NIV via either an ONM or a TFM. Mask comfort and dyspnea were assessed using visual analog scores. Other outcomes included time required to apply, vital signs and gas exchange at set time points, and early NIV discontinuation rates (ie, stoppage while still requiring ventilatory assistance).



Mask comfort and dyspnea scores were similar for both groups through 3 h of use. The time required to apply the mask (5 min [interquartile range (IQR), 2-8] vs 3.5 min [IQR, 1.9-5]), and duration of use (15.7 h [IQR, 4.0-49.8]) vs 6.05 h [IQR, 0.9-56.7]) were not significantly different between the ONM and the TFM group, respectively. Except for heart rate, which was higher at baseline in the TFM group, no differences in vital signs or gas exchange were detected between the groups during the first 3 h (P > .05). Early NIV discontinuation rates were similar for both the ONM group and TFM group (40% vs 57.1%); however, eight patients in the TFM group were switched to an ONM within 3 h, and none from the ONM group was switched to a TFM (P < .05).



Among patients with ARF requiring NIV, the ONM and TFM were perceived to be equally comfortable and had similar application times. Early NIV discontinuation rates, improvements in vital signs and gas exchange, and intubation and mortality rates were also similar.
Social support and treatment response in older depressed primary care patients.

A previously tested theoretical model that specifies relationships among depression, activities of daily living (ADL) impairment, and social support components was validated with 307 patients aged 60 and older from a multisite effectiveness trial of 3 treatments (antidepressant, placebo, Problem-Solving Treatment) for dysthymia or minor depression in primary care. Participants completed interviews and self-reports at baseline and at 6 and 12 weeks. The short-term, longitudinal data were analyzed with covariance structure modeling techniques. Consistent with the previous model, impairment in ADLs was associated with subsequent increases in depression, a larger emotionally close network that made frequent visits was associated with subsequent increases in perceived support, and perceived support was associated with subsequent decreases in depression. This last effect was significant only among participants randomly assigned to receive placebo with clinical management. The similar results in 2 different studies are a substantial validation of the theoretical model. The effect of perceived support primarily in the placebo group suggests that those with greater perceived social support and subsyndromal depression may be more likely to have a positive response to nonspecific clinical treatment components.
Small-dose ketamine improves the postoperative state of depressed patients.

We investigated whether ketamine is suitable for depressed patients who had undergone orthopedic surgery. We studied 70 patients with major depression and 25 patients as the control (Group C). The depressed patients were divided randomly into two groups; patients in Group A (n = 35) were induced with propofol, fentanyl, and ketamine and patients in Group B (n = 35) were induced with propofol and fentanyl, and all patients were maintained with 1.5%-2.0% isoflurane plus nitrous oxide. The mean Hamilton Depression Rating (HDR) score was 12.7 +/- 5.4 for Group A and 12.3 +/- 6.0 for Group B 2 days before surgery and 9.9 +/- 4.1 for Group A and 14.4 +/- 3.8 for Group B 1 day after surgery. The HDR score in Group A 1 day after surgery was significantly (P < 0.05) lower than that in Group B. The HDR score in Group C was 4.2 +/- 1.7 2 days before surgery and 4.8 +/- 1.6 1 day after surgery. Depressed mood, suicidal tendencies, somatic anxiety, and hypochondriasis significantly decreased in Group A as compared with Group B. Postoperative pain scores in Group A at 8 and 16 h after the end of anesthesia were 26.6 +/- 8.7 and 24.9 +/- 8.2, respectively, which were significantly (P < 0.05) lower than 34.3 +/- 12.0 and 31.1 +/- 8.8 in Group B. In conclusion, small-dose ketamine improved the postoperative depressive state and relieved postoperative pain in depressed patients.



NMDA receptor antagonists are reported to be effective for improving depression. It remains unclear whether ketamine, which is an NMDA receptor antagonist, postoperatively affects the psychological state in depressed patients. We investigated the effect of 1.0 mg/kg of ketamine on postoperative outcomes in depressed patients.
Three 15-min Bouts of Moderate Postmeal Walking Significantly Improves 24-h Glycemic Control in Older People at Risk for Impaired Glucose Tolerance

The purpose of this study was to compare the effectiveness of three 15-min bouts of postmeal walking with 45 min of sustained walking on 24-h glycemic control in older persons at risk for glucose intolerance.



Inactive older (≥60 years of age) participants (N=10) were recruited from the community and were nonsmoking, with a BMI<35 kg/m2 and a fasting blood glucose concentration between 105 and 125 mg dL(-1). Participants completed three randomly ordered exercise protocols spaced 4 weeks apart. Each protocol comprised a 48-h stay in a whole-room calorimeter, with the first day serving as the control day. On the second day, participants engaged in either 1) postmeal walking for 15 min or 45 min of sustained walking performed at 2) 10:30 a.m. or 3) 4:30 p.m. All walking was on a treadmill at an absolute intensity of 3 METs. Interstitial glucose concentrations were determined over 48 h with a continuous glucose monitor. Substrate utilization was measured continuously by respiratory exchange (VCO2/VO2).



Both sustained morning walking (127±23 vs. 118±14 mg dL(-1)) and postmeal walking (129±24 vs. 116±13 mg dL(-1)) significantly improved 24-h glycemic control relative to the control day (P<0.05). Moreover, postmeal walking was significantly (P<0.01) more effective than 45 min of sustained morning or afternoon walking in lowering 3-h postdinner glucose between the control and experimental day.



Short, intermittent bouts of postmeal walking appear to be an effective way to control postprandial hyperglycemia in older people.
Validation of MRI-based 3D digital atlas registration with histological and autoradiographic volumes: An anatomofunctional transgenic mouse brain imaging study

Murine models are commonly used in neuroscience to improve our knowledge of disease processes and to test drug effects. To accurately study neuroanatomy and brain function in small animals, histological staining and ex vivo autoradiography remain the gold standards to date. These analyses are classically performed by manually tracing regions of interest, which is time-consuming. For this reason, only a few 2D tissue sections are usually processed, resulting in a loss of information. We therefore proposed to match a 3D digital atlas with previously 3D-reconstructed post mortem data to automatically evaluate morphology and function in mouse brain structures. We used a freely available MRI-based 3D digital atlas derived from C57Bl/6J mouse brain scans (9.4T). The histological and autoradiographic volumes used were obtained from a preliminary study in APP(SL)/PS1(M146L) transgenic mice, models of Alzheimer's disease, and their control littermates (PS1(M146L)). We first deformed the original 3D MR images to match our experimental volumes. We then applied deformation parameters to warp the 3D digital atlas to match the data to be studied. The reliability of our method was qualitatively and quantitatively assessed by comparing atlas-based and manual segmentations in 3D. Our approach yields faster and more robust results than standard methods in the investigation of post mortem mouse data sets at the level of brain structures. It also constitutes an original method for the validation of an MRI-based atlas using histology and autoradiography as anatomical and functional references, respectively.
