Individual Versus Group Cognitive-Behavioral Therapy for Partner-Violent Men: A Preliminary Randomized Trial

A randomized clinical trial tested the hypothesis that a flexible, case formulation–based, individual treatment approach integrating motivational interviewing strategies with cognitive-behavioral therapy (ICBT) is more efficacious than a standardized group cognitive-behavioral approach (GCBT) for perpetrators of intimate partner violence (IPV). Forty-two men presenting for services at a community domestic violence agency were randomized to receive 20 sessions of ICBT or a 20-week group cognitive-behavioral therapy (CBT) program. Participants and their relationship partners completed assessments of relationship abuse and relationship functioning at baseline and quarterly follow-ups for 1 year. Treatment uptake and session attendance were significantly higher in ICBT than GCBT. However, contrary to the study hypothesis, GCBT produced consistently equivalent or greater benefits than ICBT. Participant self-reports revealed significant reductions in abusive behavior and injuries across conditions with no differential benefits between conditions. Victim partner reports revealed more favorable outcomes for group treatment, including a statistically significant difference in psychological aggression, and differences exceeding a medium effect size for physical assault, emotional abuse, and partner relationship adjustment. In response to hypothetical relationship scenarios, GCBT was associated with greater reductions than ICBT (exceeding a medium effect) in articulated cognitive distortions and aggressive intentions. Treatment competence ratings suggest that flexible, individualized administration of CBT creates challenges in session agenda setting, homework implementation, and formal aspects of relationship skills training. Although caution is needed in generalizing findings from this small-scale trial, the results suggest that the mutual support and positive social influence available in group intervention may be particularly helpful for IPV perpetrators.
Cellular and humoral immune responses against autoreactive T cells in multiple sclerosis patients after T cell vaccination.

Myelin basic protein (MBP)-reactive T cells may play an important role in the autoimmune pathogenesis of multiple sclerosis (MS). MBP-reactive T cells can be specifically targeted by T cell vaccination, a procedure whereby MS patients are immunized with attenuated autologous MBP reactive T cells. T cell vaccination induces immune responses to the vaccine cells together with a depletion of MBP reactive T cells. Forty-nine MS patients were treated with T cell vaccination in an extended phase I trial to study the safety, immune responses and clinical effects of T cell vaccination. In the present paper the immune responses towards the vaccine cells were characterized. Substantial long-term in vitro proliferative responses were observed in all treated patients. Some patients, immunized with different clones, displayed distinct proliferative reactivity against the various vaccine clones, suggesting unequal immunogenic properties of these clones. Reactive TCRalphabeta(+), CD8(+)and CD4(+)T cells, and to a lesser extent, gammadelta T cells and NK cells were observed to in vitro stimulation with the vaccine cells. A small fraction only of CD8(+)T cells expressed cytolytic and inhibitory anti-clonotypic reactivity against the vaccine cells. Stimulation with the vaccine clones predominantly induced expression of pro-inflammatory cytokines in these mixed cultures, although one vaccine clone consistently induced production of IL-4. CD4(+)T cells are the major cytokine-producing cells in these anti-vaccine lines. We could not detect upregulated antibody responses to the vaccine cells in most patients, although a temporary antibody response was observed in one patient. In conclusion, immunization with attenuated autoreactive T cells induces a complex cellular response specifically targeted at the vaccine cells, but no antibody responses. These data provide further insights into the mechanisms of T cell vaccination and improve our understanding of the complex regulatory networks of autoreactive T cells.
Constitutive deficiency in DNA mismatch repair: is it time for Lynch III?

Hereditary non‐polyposis colorectal cancer (HNPCC), also known as Lynch syndrome types I and II, and the related subtypes Turcot and Muir–Torre syndrome, have all been associated with inheritance of germ line mutations in the DNA mismatch repair (MMR) genes. Fifty individuals have recently been identified with an early onset of a different spectrum of cancers associated with inheritance of two MMR mutations – resulting either in a constitutive loss of MMR function, or greatly impaired MMR function. In contrast to Lynch I and II individuals, individuals with inheritance of homozygous or compound heterozygous mutations in the MMR genes that result in a complete lack of protein, present with hematological and brain malignancies in the first decade of life. Biallelic mutations with compromised but residual protein function present with a broader spectrum of cancers (brain, hematological or gastrointestinal) in the second to fourth decades of life. We propose that inheritance of two MMR mutations in an individual and the unique tumor spectrum that occurs with an early onset should be defined separately from Lynch syndrome I and II, or the subtypes Turcot and Muir–Torre. We suggest Lynch III as an appropriate name for identifying individuals with constitutively compromised MMR associated with biallelic mutations.
Characterization of the neoplastic phenotype in the familial atypical multiple‐mole melanoma–pancreatic carcinoma syndrome

Previous studies suggest that the familial atypical multiple‐mole melanoma (FAMMM) syndrome may predispose affected families to nonmelanoma carcinomas, including adenocarcinoma of the pancreas. It has been found that many of these families harbor mutations in the CDKN2A gene on chromosome 9p21. The phenotypic expression of CDKN2A mutations in these families has not been characterized fully.
Promoting Health in Type 2 Diabetes: Nurse-Physician Collaboration in Primary Care

The purpose of this study is to examine effects of a nurse-physician collaborative approach to care of patients with type 2 diabetes and to determine possible effect sizes for use in computing sample sizes for a larger study. Forty patients from a family practice clinic with type 2 diabetes were randomly assigned to control or experimental groups. The control group received standard care, whereas the experimental group received standard care plus home visits from a nurse, as well as consultation with an exercise specialist and/or nutritionist. Follow-up continued for 3 months. Clinical end points included standard measures of diabetes activity as well as quality-of-life indicators. Focus group interviews were used to explore patients’ responses to the program. Although findings were not statistically significant, a trend toward small to moderate positive effect sizes was found in glycosylated hemoglobin and blood pressure. Quality oflife measures also showed a trend toward small to moderate, but nonsignificant, improvements in physical functioning, bodily pain, vitality, social and global functioning, energy, impact of diabetes, and health distress. Focus group interviews indicated a very positive response from patients, who expressed feelings of empowerment. In this study, patients treated with nurse-physician collaboration demonstrated small, but nonsignificant, improvements in blood chemistry after only 3 months. Physical and social functioning, energy, and bodily pain also showed a small improvement. Changes in awareness of effects of diabetes on health and an expressed sense of self-efficacy suggest that effects could be sustainable over the longer term.
Peginterferon alfa-2a (40KD) plus ribavirin in chronic hepatitis C patients who failed previous interferon therapy

Background: The management of patients with chronic hepatitis C who have relapsed or failed to respond to interferon based therapies is an important issue facing hepatologists. Aims: We evaluated the efficacy and safety of peginterferon alfa-2a (40KD) plus ribavirin in this population by conducting a multicentre open label study. Patients: Data from adults with detectable serum hepatitis C virus (HCV) RNA who had not responded or had relapsed after previous conventional interferon or conventional interferon/ribavirin combination therapy were analysed. Methods: Patients were retreated with peginterferon alfa-2a (40KD) 180 µg/week plus ribavirin 800 mg/day for 24 or 48 weeks at the investigators’ discretion. The study was conceived before the optimal dose of ribavirin (1000/1200 mg/day) for patients with genotype 1 was known. The primary endpoint was sustained virological response (SVR), defined as undetectable HCV RNA (<50 IU/ml) after 24 weeks of follow up. The analysis was conducted by intention to treat. Results: A total of 312 patients (212 non-responders, 100 relapsers) were included. Of these, 28 patients were treated for 24 weeks and 284 for 48 weeks. Baseline characteristics between non-responders and relapsers were similar although more non-responders had genotype 1 infection (87% v 69%). Overall SVR rates were 23% (48/212) for non-responders and 41% (41/100) for relapsers. When data were analysed by genotype, SVR rates were 24% (61/253) in genotype 1 and 47% (28/59) in genotype 2/3. Conclusions: These results in a large patient cohort demonstrate that it is possible to cure a proportion of previous non-responders and relapsers by retreating with peginterferon alfa-2a (40KD) plus ribavirin.
The effects of magnetic field on the biomechanics parameters of soleus and extensor digitorum longus muscles in rats with streptozotocin-induced diabetes.

BACKGROUND The aim of this study was to determine the effects of the magnetic field (MF) on the isometric contractile characteristics of the soleus and extensor digitorum longus (EDL) muscles in rats both with and without diabetes. METHODS Biomechanical parameters were recorded in vitro from Wistar rats without diabetes (Group I, n=20), rats without diabetes exposed to MF (Group II, n=20), rats with streptozotocin-induced diabetes (Group III, n=20), and rats with diabetes exposed to MF (Group IV, n=20). Muscle strips were taken from the distal tendon soleus and EDL muscles of rats killed by decapitation. The muscles were hung in organ baths containing Krebs solution (pH 7.4) with a gas mixture of 95% O2 and 5% CO2. Then the muscles were triggered to direct supramaximal stimulation with 0.05 Hz frequency square pulses for periods of 0.5 ms to obtain control values. The contractile parameters were also determined for two muscles of the four groups. Later, the tension-frequency relationship was determined by applying stimulating pulses of 10, 20, 50, and 100 Hz to the muscles. RESULTS Diabetes caused a certain amount of decrease in the contractile force of the two muscles compared with that of control values. However, MF increased the contractile force of the two muscles in rats both with and without diabetes. The isometric contraction forces obtained by different stimulating frequencies showed a significant linear increase in the tetanic contraction (P<0.05). Diabetes increased the contraction time of the isometric twitch tension compared with that of the control group with a statistically significant difference (P<0.05). MF decreased the contraction time of the two muscles of rats without diabetes (P<0.05) but increased that of rats with diabetes (P>0.05). CONCLUSION In our study, these results suggest that MF exposure regulates the isometric contractile characteristics of the soleus and EDL muscles of rats with diabetes, positively.
Biochemical characteristics of different forms of protein-energy malnutrition: an experimental model using young rats

1. In three separate experiments, four groups of five to eight young male rats were fed either (i) a high-protein diet, for which the net dietary protein: total metabolizable energy ratio (NDp:E) was 0.1 (HP diet); or (ii) a low-protein diet, for which NDP:E was 0.04 (LP diet). In both these groups, food intake was ad lib In group (iii) the HP diet was given in an amount approximately equal to that taken by the LP group fed ad lib. (HP-restricted). In group (iv) rats were fasted for 48 h after receiving the HP diet (HP-fasted). Each experiment lasted 4 weeks. 2. In the LP and HP-restricted groups, food intake was about 50% of that of the HP rats, while body-weight, after 4 weeks on diet was about 35% and 55% of that of HP rats, for LP and HP-restricted respectively. Both groups of malnourished rats gained some weight during the experiment. 3. Measurements of oral glucose tolerance and plasma insulin levels were made in the fourth week. LP and HP-restricted rats both showed low fasting insulin levels and low insulin to glucose ratios during the glucose tolerance tests; the LP rats were more seriously affected. 4. At the end of the fourth week the rats were killed and blood, liver and gastrocnemius muscle were analysed. LP rats showed specifically and consistently low values for haemoglobin and plasma protein concentration, and low activities of hepatic glucose-6-phosphatase (EC 3.1.3.9) and of alanine aminotransferase (EC 2.6.1.2) in liver and muscle. The activity of hepatic aspartate aminotransferase (EC 2.6.1.1) was, if anything, increased. The plasma amino acid concentrations and ratios showed a specific fall in branched-chain amino acids. Liver fat concentration was consistently elevated. The HP-restricted rats had normal values for haemoglobin, plasma protein and liver fat, and near-normal values for plasma amino acids. Hepatic alanine aminotransferase showed increased activity compared with HP rats, but muscle alanine aminotransferase showed reduced activity. The HP-fasted rats had increased haemoglobin, plasma protein and liver fat concentration, and very low liver glycogen concentrations. Hepatic alanine aminotransferase activity was elevated. Plasma alanine concentration was specifically reduced. 5. The results are consistent with suppression of gluconeogenesis, liver dysfunction and essential amino acid deprivation in LP rats. These biochemical changes found in rats on a low intake of a diet of low protein and high carbohydrate value are similar to those found in kwashiorkor. An equally low intake of a diet of good protein value (HP-restricted) led to marginally better growth, accompanied by biochemical signs of increased gluconeogenesis, analogous to those reported for nutritional marasmus. This nutritional state was not biochemically identical with that of acute fasting. 6. The results are discussed in terms of the consistency of the rat model, and its contribution to understanding biochemical changes found in infant malnutrition.
Clinical impact of human herpesvirus 6 infection after liver transplantation.

BACKGROUND Reactivation of human herpesvirus 6 (HHV-6) appears to be common after transplant. Viral reactivation may result in febrile illness and may also play an immunomodulatory role that leads to indirect effects such as opportunistic infections and rejection. The objective of this study was to determine the clinical impact of HHV-6 infection after liver transplantation including both direct and indirect effects. METHODS This was a prospective single center cohort study of 200 consecutive patients undergoing liver transplantation. Systemic serial HHV-6 viral load measurements and all clinical outcomes including development of opportunistic infections, cytomegalovirus (CMV) disease, and rejection were determined. RESULTS HHV-6 infection (defined as viral load > or = 2 log10 copies/microg input DNA) occurred in 56/200 (28%) patients. Symptomatic disease attributable to HHV-6 alone occurred in 2/200 (1%) patients. Univariate analysis revealed HHV-6 infection was associated with the development of opportunistic infection and CMV disease. In a multivariate analysis designed to control for the level of immunosuppression, the risk of opportunistic infection increased by 3.68-fold in patients with HHV-6 infection (95% confidence interval [CI], 1.86-7.27; P=0.001). In a similar multivariate analysis, the risk of CMV disease increased by 3.59-fold in patients with HHV-6 infection (95% CI, 1.53-8.44; P=0.003). HHV-6 infection was not associated with rejection except in the subgroup of patients with rejection after 30 days posttransplant (odds ration 2.27; 95% CI, 1.09-4.77; P=0.029). CONCLUSIONS HHV-6 reactivation after transplant is common and is associated with the development of opportunistic infections and CMV disease and possibly with a subgroup of acute rejection episodes. HHV-6 infection likely has a significant impact in transplant recipients through indirect effects of viral replication.
Preclinical atherosclerosis in patients with inflammatory bowel diseases: a case-control study.

BACKGROUND An independent role of chronic inflammation in the atherosclerotic process in patients with inflammatory bowel diseases (IBD) has been suggested, but data are still contentious. We assessed pre-clinical atherosclerosis in the IBD patients without traditional risk factors. METHODS In this case-control study we assessed the early atherosclerotic alterations by carotid artery intima-media thickness (CIMT) measurement in IBD patients and matched controls. The normal CIMT values were ≤0.9 mm; moderate thickness when >0.9 and ≤1.2 mm, and pre-clinical atherosclerosis when >1.2 mm. We selected a homogeneous group of IBD patients, all in ongoing biologic therapy, without any traditional risk factor for atherosclerosis as well as controls. RESULTS The study enrolled 23 consecutive patients (16 with ulcerative colitis and 7 with Crohn's disease) and 20 controls matched for age and sex. The mean of CIMT values was not statistically different between patients and controls (0.68±0.21 vs. 0.82±0.2 mm; P=0.4). The prevalence of moderate CIMT thickness was significantly lower in cases than in controls (8.7% vs. 42.8%; P=0.01; OR: 0.15, 95% CI: 0.03-0.85). CONCLUSIONS This case-control study found that the atherosclerotic process is not more apparent in IBD patients without traditional risk factors.
Iron and Folate in Fortified Cereals

Background: Fortification of cereal-grain products was introduced in 1941 when iron and three vitamins were added to flour and bread. Ready-to-eat cereals were fortified at about the same time. These fortifications have contributed to increased dietary iron intake and reductions in iron deficiency anemia in the US. In 1996, FDA finalized rules for fortification of specific enriched cereal-grain products with folic acid. This measure was instituted to increase the folate intakes of women of child-bearing age and thereby reduce the risk of having a pregnancy affected with a neural tube birth defect. However, with recent increases in fortification, public health officials in the US are concerned that excess intake of specific nutrients such as iron and folic acid may result in toxic manifestations. Objective: Our objective was to measure iron and total folate content in breakfast cereals and compare assay to label values for % Daily Value. We also determined by weight the amount of a ready-to-eat breakfast cereal adults would eat and compared this to the labeled serving size, for which the reference amount for this cereal per eating occasion was 1 cup or 30 g. Design: Twenty-nine breakfast cereals were analyzed for iron content using the bathophenanthroline reaction. Twenty-eight cereals were analyzed for total folate, utilizing a microbiological assay with tri-enzyme digestion. Serving size quantities were estimated in seventy-two adults who regularly ate breakfast cereal and were asked to fill a 16 or 22 cm round bowl with the amount of cereal that they would consume for breakfast. Results: When the labeled value was compared to the assayed value for iron content 21 of the 29 breakfast cereals were 120% or more of the label value and 8 cereals were 150% or more of the label value. Overall, analyzed values for iron ranged from 80% to 190% of label values. Analyzed values for folate ranged from 98% to 320% of label values. For 14 of 28 cereals, analyzed values exceeded label declarations by more than 150%. Bran-containing cereals contained the highest amounts of folate relative to their label declarations. The median analyzed serving size for the breakfast cereal was 47 g for females, 61 g for males with a combined median of 56 g as compared to the label value of 30 g. Conclusions: Analyzed values of iron and folic acid in breakfast cereals were considerably higher than labeled values. For adults, the amount of cereal actually consumed was approximately 200% of the labeled serving size. When the quantity of cereal consumed is more than the labeled serving size and when the levels of iron and folate are higher than declared, the intake of both will be significantly greater than the labeled values. It will be important to continue monitoring serum ferritin and folate levels in NHANES IV, since daily consumption of breakfast cereals may contribute to excessive intakes of iron and folate.
Focused ion beam‐scanning electron microscope: exploring large volumes of atherosclerotic tissue

Atherogenesis is a pathological condition in which changes in the ultrastructure and in the localization of proteins occur within the vasculature during all stages of the disease. To gain insight in those changes, high‐resolution imaging is necessary. Some of these changes will only be present in a small number of cells, positioned in a ‘sea’ of non‐affected cells. To localize this relatively small number of cells, there is a need to first navigate through a large area of the sample and subsequently zoom in onto the area of interest. This approach enables the study of specific cells within their in vivo environment and enables the study of (possible) interactions of these cells with their surrounding cells/environment. The study of a sample in a correlative way using light and electron microscopy is a promising approach to achieve this; however, it is very laborious and additional ultrastructural techniques might be very valuable to find the places of interest.
A logistic model including risk factors for lymph node metastasis can improve the accuracy of magnetic resonance imaging diagnosis of rectal cancer.

BACKGROUND To evaluate use of magnetic resonance imaging (MRI) and a logistic model including risk factors for lymph node metastasis for improved diagnosis. MATERIALS AND METHODS The subjects were 176 patients with rectal cancer who underwent preoperative MRI. The longest lymph node diameter was measured and a cut-off value for positive lymph node metastasis was established based on a receiver operating characteristic (ROC) curve. A logistic model was constructed based on MRI findings and risk factors for lymph node metastasis extracted from logistic-regression analysis. The diagnostic capabilities of MRI alone and those of the logistic model were compared using the area under the curve (AUC) of the ROC curve. RESULTS The cut-off value was a diameter of 5.47 mm. Diagnosis using MRI had an accuracy of 65.9%, sensitivity 73.5%, specificity 61.3%, positive predictive value (PPV) 62.9%, and negative predictive value (NPV) 72.2% [AUC: 0.6739 (95%CI: 0.6016-0.7388)]. Age (<59) (p=0.0163), pT (T3+T4) (p=0.0001), and BMI (<23.5) (p=0.0003) were extracted as independent risk factors for lymph node metastasis. Diagnosis using MRI with the logistic model had an accuracy of 75.0%, sensitivity 72.3%, specificity 77.4%, PPV 74.1%, and NPV 75.8% [AUC: 0.7853 (95%CI: 0.7098-0.8454)], showing a significantly improved diagnostic capacity using the logistic model (p=0.0002). CONCLUSIONS A logistic model including risk factors for lymph node metastasis can improve the accuracy of MRI diagnosis of rectal cancer.
