The effect of consumption of low-glycemic-index and low-glycemic-load desserts on anthropometric parameters and inflammatory markers in patients with type 2 diabetes mellitus.

The aim of the present study was to examine the effects of consumption of desserts with low glycemic index (GI) and low glycemic load (GL), as part of a balanced hypo-caloric diet, on anthropometric and biochemical parameters in patients with type 2 diabetes mellitus (T2DM).



A total of 61 subjects with T2DM were randomly assigned to the intervention (n = 30) or to the control group (n = 31). Both groups followed the same hypo-caloric (-500 kcal) diet for 12 weeks. Consumption of four portions of low-GI/low-GL desserts/week was included in the diet in the intervention group while one portion of a favorite usual sweet/week was allowed to be consumed in the control group.



Thirty subjects in the control and 28 subjects in the intervention group completed the trial. Body weight, body mass index, and waist circumference were reduced significantly in both groups. Arterial blood pressure, fasting blood glucose, glycosylated hemoglobin, insulin, and γ-GT were reduced significantly only in the intervention group; however, there were no significant differences between the two groups at endpoint. C-reactive protein was reduced in the intervention, and HDL cholesterol was also reduced in the control group; the reductions were significantly different at the end of the trial. No significant changes were observed in the other plasma lipids, uric acid, leptin, adiponectin, and interleukin-6 in either study group.



Consumption of desserts with low GI/GL in a balanced hypo-caloric diet has a positive impact on anthropometric and metabolic parameters of patients with T2DM.
Predictors of short-term changes in serum intact parathyroid hormone levels in hemodialysis patients: role of phosphorus, calcium, and gender.

Several factors have been identified as important in the pathogenesis of secondary hyperparathyroidism in end-stage renal disease, including serum calcium, phosphorus, and calcitriol. To examine the independent effects of key factors, we prospectively studied 52 new hemodialysis patients with mild secondary hyperparathyroidism (PTH, 110-670 pg/mL) treated with a standardized regimen of calcium supplements, phosphorus binders, and no vitamin D derivatives. We used simple and multivariable linear regression analysis to examine the relationship between changes in PTH (deltaPTH) levels observed over a 4-week period and various biochemical and demographic variables. By simple linear regression we found that changes in serum phosphorus (r2 = 0.31; beta = 41.6; P = 0.0001), initial phosphorus concentration (r2 = 0.15; beta = 33.4; P = 0.005), initial PTH level (r2 = 0.29; beta = 0.58; P = 0.0001), changes in serum calcium (r2 = 0.12; beta = -74.0; P = 0.01), and gender (r2 = 0.07; beta = 76.1; P = 0.05) were significantly associated with deltaPTH. However, upon multivariable regression analysis, only the changes in phosphorus (partial r2 = 0.31; beta = 37.0; P = 0.0001), initial PTH level (partial r2 = 0.23; beta = 0.50; P = 0.0001), and gender (partial r2 = 0.05; beta = 63.1; P = 0.02) remained significantly associated with deltaPTH. Neither the serum concentration of 1,25-dihydroxyvitamin D3, bicarbonate, aluminum, or albumin nor changes in the serum bicarbonate concentration, the presence of diabetes, KT/V, or age were significantly associated with the deltaPTH. Our findings are consistent with independent effects of phosphorus and gender on parathyroid gland function in patients with dialysis-dependent renal failure through mechanisms that remain to be defined.
Assessment of Disease‐Related Therapeutic Protein Drug‐Drug Interaction for Etrolizumab in Patients With Moderately to Severely Active Ulcerative Colitis

The efficacy and safety of etrolizumab, a humanized IgG1 mAb, were evaluated in patients with ulcerative colitis (UC) in a phase 2 study (EUCALYPTUS). The current study assessed the risk of therapeutic protein drug-drug interaction (TP-DDI) of etrolizumab on CYP3A activity in patients with UC. Literature review was performed to compare serum proinflammatory cytokine levels and pharmacokinetic (PK) parameters of CYP3A substrate drugs between patients with inflammatory bowel disease (IBD) and healthy subjects. Treatment effect of etrolizumab on CYP3A activity was evaluated by measuring colonic CYP3A4 mRNA expression and serum C-reactive protein (CRP) in EUCALYPTUS patients. Literature data suggested similar levels between IBD patients and healthy subjects for serum proinflammatory cytokines and PK parameters of CYP3A substrate drugs. Additionally, treatment with etrolizumab did not change colonic CYP3A4 mRNA expression or serum CRP levels in UC patients. In conclusion, our results indicate a low TP-DDI risk for etrolizumab in UC patients, particularly on medications metabolized by CYP3A.
Effects of an evidence service on community-based AIDS service organizations' use of research evidence: A protocol for a randomized controlled trial

To support the use of research evidence by community-based organizations (CBOs) we have developed 'Synthesized HIV/AIDS Research Evidence' (SHARE), which is an evidence service for those working in the HIV sector. SHARE consists of several components: an online searchable database of HIV-relevant systematic reviews (retrievable based on a taxonomy of topics related to HIV/AIDS and open text search); periodic email updates; access to user-friendly summaries; and peer relevance assessments. Our objective is to evaluate whether this 'full serve' evidence service increases the use of research evidence by CBOs as compared to a 'self-serve' evidence service.



We will conduct a two-arm randomized controlled trial (RCT), along with a follow-up qualitative process study to explore the findings in greater depth. All CBOs affiliated with Canadian AIDS Society (n = 120) will be invited to participate and will be randomized to receive either the 'full-serve' version of SHARE or the 'self-serve' version (a listing of relevant systematic reviews with links to records on PubMed and worksheets that help CBOs find and use research evidence) using a simple randomized design. All management and staff from each organization will be provided access to the version of SHARE that their organization is allocated to. The trial duration will be 10 months (two-month baseline period, six-month intervention period, and two month crossover period), the primary outcome measure will be the mean number of logins/month/organization (averaged across the number of users from each organization) between baseline and the end of the intervention period. The secondary outcome will be intention to use research evidence as measured by a survey administered to one key decision maker from each organization. For the qualitative study, one key organizational decision maker from 15 organizations in each trial arm (n = 30) will be purposively sampled. One-on-one semi-structured interviews will be conducted by telephone on their views about and their experiences with the evidence service they received, how helpful it was in their work, why it was helpful (or not helpful), what aspects were most and least helpful and why, and recommendations for next steps.



To our knowledge, this will be the first RCT to evaluate the effects of an evidence service specifically designed to support CBOs in finding and using research evidence.
Secondary solid tumors after allogeneic hematopoietic SCT in Japan

To evaluate the incidence and risk factors for secondary solid tumors in Japan after allogeneic hematopoietic SCT (allo-HSCT), 2062 patients who had received allo-HSCT between 1984 and 2005 were retrospectively analyzed. Twenty-eight patients who developed 30 solid tumors were identified a median of 5.6 years after transplantation. The risk for developing tumors was 2.16-fold higher than that of the age- and sex-adjusted general population. The cumulative incidence of solid tumors at 10 years after allo-HSCT was 2.4%. The risk was significantly higher for tumors of the skin, oral cavity and esophagus (standard incidental ratio 40.23, 35.25 and 10.73, respectively). No increase in gastric, colon or lung cancer, despite being the most prevalent neoplasm in the Japanese, was observed. In multivariate analysis, occurrence of chronic GVHD and malignant lymphoma as a primary disease was associated with a higher risk for developing solid tumors. Eighteen patients are still alive, and their 5-year probability of survival since diagnosis of solid tumors is 59.7%. Our data suggest that the incidence and risk factors of secondary solid tumors in Japanese allo-HSCT recipients are comparable to those reported in Western countries and emphasize that the early detection of solid tumors has a crucial role in improving OS.
MODERN TREATMENT YEAR BOOK, 1945

can be carried out. This should ensure more adequate material and better facilities for the teaching of, not only undergraduates, but also postgraduates. But when our new organisation is completed will we be in Utopia? That depends as always on us as individuals. In the highly scientific age of the last century perhaps the machine has had more attention than the man. Perhaps disease has had more attention than the patient. Let us remember that the microscope does not observe nor do our books think. The reputation of a Medical School will depend not so much on its hospital and laboratories as upon the character and ability of both its students and teachers. 4 THIS Year Book has won a well-deserved place in the affections of many practitioners, and the current volume will enhance its reputation. The galaxy of brilliant contributors is a guarantee of the authenticity and interest of the work. The subject matter has been chosen with some care, and there is not a single dull page in the volume. One doubts whether the section on the treatment of cerebro-spinal fever represents present-day views on this important subject. The type is legible and pleasant to read; the paper is 'ersatz'; the illustrations are excellent.
A study of losartan, alone or with hydrochlorothiazide vs nifedipine GITS in elderly patients with diastolic hypertension

We conducted a randomised, double-blind, parallel design study comparing the efficacy and tolerability of the angiotensin II receptor antagonist, losartan, alone or with low-dose hydrochlorothiazide (HCTZ) to the dihydropyridine calcium channel blocker, nifedipine GITS (gastro-intestinal therapeutic system), in elderly patients (⩾65 years old) with a diastolic blood pressure (DBP) between 95 and 115 mm Hg. After a placebo wash out period, 140 patients were randomly assigned to receive either losartan 50 mg or nifedipine GITS 30 mg. Patients were evaluated at 4-week intervals during a 12-week treatment period. Patients receiving losartan had HCTZ 12.5 mg added and increased to 25 mg to reduce DBP <90 mm hg. patients receiving nifedipine gits had their dose increased to 60 mg and 90 mg to reduce dbp <90 mm hg. efficacy, tolerability and quality of life were assessed during the 12 weeks on each regimen. patients treated with the losartan regimen (n = 73) had reductions in trough sitting DBP of −10, −13, and −13 mm Hg after 4, 8, and 12 weeks of therapy, respectively. Patients receiving the nifedipine GITS regimen (n = 67) had DBP reductions of −14, −15, and −15 mm Hg, respectively. There were no significant differences in the DBP response between the treatment groups except at week 4 (P < 0.05). similar reductions in systolic bp (sbp) between the two treatment groups were observed at all time points. the percentages of patients in the two treatment groups reaching goal dbp (<90 mm hg or dbp ⩾90 mm hg with a reduction from a baseline of ⩾10 mm hg) were comparable (81% on the losartan regimen and 90% on the nifedipine gits regimen). there were significantly more adverse events reported in patients receiving nifedipine gits when compared to the losartan regimen (54% vs 36%, P < 0.05). a patient-reported symptom inventory also showed that swollen ankles was bothersome in significantly more patients treated with the nifedipine gits regimen when compared to the losartan regimen (24% vs 5%, P = 0.001). Thus, in elderly patients with diastolic hypertension, a regimen of losartan alone or with HCTZ has similar efficacy to a regimen of nifedipine GITS with greater tolerability and less symptom bother due to swollen ankles.
Prevention of depression in at-risk adolescents: a randomized controlled trial.

Adolescent offspring of depressed parents are at markedly increased risk of developing depressive disorders. Although some smaller targeted prevention trials have found that depression risk can be reduced, these results have yet to be replicated and extended to large-scale, at-risk populations in different settings.



To determine the effects of a group cognitive behavioral (CB) prevention program compared with usual care in preventing the onset of depression.



A multicenter randomized controlled trial conducted in 4 US cities in which 316 adolescent (aged 13-17 years) offspring of parents with current or prior depressive disorders were recruited from August 2003 through February 2006. Adolescents had a past history of depression, current elevated but subdiagnostic depressive symptoms, or both. Assessments were conducted at baseline, after the 8-week intervention, and after the 6-month continuation phase.



Adolescents were randomly assigned to the CB prevention program consisting of 8 weekly, 90-minute group sessions followed by 6 monthly continuation sessions or assigned to receive usual care alone.



Rate and hazard ratio (HR) of a probable or definite depressive episode (ie, depressive symptom rating score of > or = 4) for at least 2 weeks as diagnosed by clinical interviewers.



Through the postcontinuation session follow-up, the rate and HR of incident depressive episodes were lower for those in the CB prevention program than for those in usual care (21.4% vs 32.7%; HR, 0.63; 95% confidence interval [CI], 0.40-0.98). Adolescents in the CB prevention program also showed significantly greater improvement in self-reported depressive symptoms than those in usual care (coefficient, -1.1; z = -2.2; P = .03). Current parental depression at baseline moderated intervention effects (HR, 5.98; 95% CI, 2.29-15.58; P = .001). Among adolescents whose parents were not depressed at baseline, the CB prevention program was more effective in preventing onset of depression than usual care (11.7% vs 40.5%; HR, 0.24; 95% CI, 0.11-0.50), whereas for adolescents with a currently depressed parent, the CB prevention program was not more effective than usual care in preventing incident depression (31.2% vs 24.3%; HR, 1.43; 95% CI, 0.76-2.67).



The CB prevention program had a significant prevention effect through the 9-month follow-up period based on both clinical diagnoses and self-reported depressive symptoms, but this effect was not evident for adolescents with a currently depressed parent.
Motion of the rearfoot, ankle and subtalar joints and ankle moments when wearing lateral wedge insoles – results from bone anchored markers

Knee osteoarthritis is a debilitating condition and increased dynamic loading at the knee has been linked with increased progression of the disease. Lateral wedge insoles have been used in clinical practice since the late 1980s. It is theorised that lateral wedge insoles increase the subtalar joint valgus orientation and increase the ankle valgus moment , with subsequent reduced knee varus moments [2]. Results have shown that both clinical success and reductions in knee loading vary between people. Differences could be due to person specific foot biomechanics. The aim of this study was to determine the changes in frontal plane foot and ankle motion and moment due to a lateral wedge orthosis.
Antipsychotic Dose Mediates the Association between Polypharmacy and Corrected QT Interval

Antipsychotic (AP) drugs have the potential to cause prolongation of the QT interval corrected for heart rate (QTc). As this risk is dose-dependent, it may be associated with the number of AP drugs concurrently prescribed, which is known to be associated with increased cumulative equivalent AP dosage. This study analysed whether AP dose mediates the relationship between polypharmacy and QTc interval. We used data from a cross-sectional survey that investigated the prevalence of QTc lengthening among people with psychiatric illnesses in Italy. AP polypharmacy was tested for evidence of association with AP dose and QTc interval using the Baron and Kenny mediational model. A total of 725 patients were included in this analysis. Of these, 186 (26%) were treated with two or more AP drugs (AP polypharmacy). The mean cumulative AP dose was significantly higher in those receiving AP polypharmacy (prescribed daily dose/defined daily dose = 2.93, standard deviation 1.31) than monotherapy (prescribed daily dose/defined daily dose = 0.82, standard deviation 0.77) (z = -12.62, p < 0.001). Similarly, the mean QTc interval was significantly longer in those receiving AP polypharmacy (mean = 420.86 milliseconds, standard deviation 27.16) than monotherapy (mean = 413.42 milliseconds, standard deviation 31.54) (z = -2.70, p = 0.006). The Baron and Kenny mediational analysis showed that, after adjustment for confounding variables, AP dose mediates the association between polypharmacy and QTc interval. The present study found that AP polypharmacy is associated with QTc interval, and this effect is mediated by AP dose. Given the high prevalence of AP polypharmacy in real-world clinical practice, clinicians should consider not only the myriad risk factors for QTc prolongation in their patients, but also that adding a second AP drug may further increase risk as compared with monotherapy.
Venous thromboembolic events are rare after shoulder surgery: analysis of a national database.

Data on venous thromboembolic (VTE) events after different types of shoulder surgery have not previously been available in large numbers in the United Kingdom. We aimed to determine baseline postoperative complication rates with reference to national thromboembolic prophylaxis guidelines.



Diagnostic and operative codes are routinely collected on every patient admitted to the hospital in the English NHS. Data for a 42-month period were analyzed for planned shoulder surgery (total replacement, hemiarthroplasty, or arthroscopy) and proximal humeral fracture surgery (internal fixation or replacement). In addition, complications during the two 6-month periods before and after the implementation of national thromboprophylaxis guidelines were compared. Rates of symptomatic deep venous thrombosis, pulmonary embolism, and mortality within 90 days were extracted.



For total shoulder replacement (4,061 patients), deep venous thrombosis, pulmonary embolism, and mortality rates were 0%, 0.20%, and 0.22%, respectively. For arthroscopic procedures (65,302 patients), the rates were less than 0.01%, 0.01%, and 0.03%, respectively. For proximal humeral fracture surgery (internal fixation or replacement, 4,696 patients), the rates were 0.19%, 0.40%, and 3.02%, respectively. There was no significant difference in the VTE event or mortality rates before and after the introduction of the 2007 National Institute for Health and Clinical Excellence guidelines after arthroscopy or proximal humeral fracture surgery. A statistically significant decrease in total shoulder replacement-related mortality was found, from 0.72% (5 patients) to 0%.



VTE disease is not a significant problem after shoulder surgery, and thromboprophylaxis may not be required, even in high-risk patients. National thromboprophylaxis guidelines did not affect VTE event rates.
Absent event-related potential (ERP) word repetition effects in mild Alzheimer's disease

We hypothesized that an ERP word repetition paradigm, which reliably elicits and modulates the P600 and N400 components, would be particularly sensitive to the memory deficits and altered synaptic plasticity in mild Alzheimer's disease (AD). The P600 (a late positive component, or 'LPC'), and the N400, are sensitive indices of memory encoding and semantic processing, respectively.



We studied 11 patients with mild AD (mean MMSE=22.9) and 11 elderly (mean age=77.1) normal controls (NC) on a paradigm in which semantically 'congruous' category statement/exemplar pairs (50%) and 'incongruous' category statement/non-exemplar pairs (50%) repeat at 10-140 s intervals. A minimum of 19 channels ERP data were recorded and submitted to split-plot ANOVAs.



Normal ERP data showed: (1) a significant word repetition effect for congruous words, with a wide-spread late positivity between approximately 300 and 800 ms post-stimulus (P600) that is larger for New than Old words; (2) a significant N400 repetition effect for incongruous words, with a right posterior negativity that is reduced for Old relative to New words. By contrast, neither of these word repetition effects was reliably present in the mild AD group. Good group discrimination was achieved by requiring that both these repetition effects were > or = the 10th percentile, with 100% sensitivity and 82% specificity.



We found significant abnormalities of the N400 and P600 in mild AD, with both potentials showing markedly reduced sensitivity to word repetition.



The absence of normal N400 and LPC/P600 word repetition effects suggests impaired functioning of their neural generators, several of which are located in medial temporal lobe predilection sites (e.g. anterior fusiform, parahippocampal gyrus, hippocampus) for AD/tau pathology.
Moderate amounts of fructose- or glucose-sweetened beverages do not differentially alter metabolic health in male and female adolescents.

Adolescents consume more sugar-sweetened beverages than do individuals in any other age group, but it is unknown how the type of sugar-sweetened beverage affects metabolic health in this population.



The objective was to compare the metabolic health effects of short-term (2-wk) consumption of high-fructose (HF) and high-glucose (HG)-sweetened beverages in adolescents (15-20 y of age).



In a counterbalanced, single-blind fashion, 40 male and female adolescents completed two 2-wk trials that included 1) an HF trial in which they consumed 710 mL of a sugar-sweetened beverage/d (equivalent to 50 g fructose/d and 15 g glucose/d) for 2 wk and 2) an HG trial in which they consumed 710 mL of a sugar-sweetened beverage/d (equivalent to 50 g glucose/d and 15 g fructose/d) for 2 wk in addition to their normal ad libitum diet. In addition, the participants maintained similar physical activity levels during each trial. The day after each trial, insulin sensitivity and resistance [assessed via Quantitative Insulin Sensitivity Check Index (QUICKI) and homeostatic model assessment of insulin resistance (HOMA-IR) index] and fasting and postprandial glucose, lactate, lipid, cholesterol, insulin, C-peptide, insulin secretion, and clearance responses to HF or HG mixed meals were assessed.



Body weight, QUICKI (whole-body insulin sensitivity), HOMA-IR (hepatic insulin resistance), and fasting lipids, cholesterol, glucose, lactate, and insulin secretion or clearance were not different between trials. Fasting HDL- and HDL₃-cholesterol concentrations were ∼10-31% greater (P < 0.05) in female adolescents than in male adolescents. Postprandial triacylglycerol, HDL-cholesterol, HDL₃-cholesterol, and glucose concentrations were not different between HF and HG trials. The lactate incremental area under the curve was ∼3.7-fold greater during the HF trial (P < 0.05), whereas insulin secretion was 19% greater during the HG trial (P < 0.05).



Moderate amounts of HF- or HG-sweetened beverages for 2 wk did not have differential effects on fasting or postprandial cholesterol, triacylglycerol, glucose, or hepatic insulin clearance in weight-stable, physically active adolescents.
