Decreased transfusion requirements for patients receiving nonmyeloablative compared with conventional peripheral blood stem cell transplants from HLA-identical siblings.

Red blood cell (RBC) and platelet transfusion requirements in patients given nonmyeloablative versus conventional peripheral blood stem cell (PBSC) transplants from HLA-matched siblings were compared. Between December 1997 and March 2000, 40 patients, aged 21 to 67 years (median 51), with hematologic malignancies underwent nonmyeloablative allografts after either 2 Gy total body irradiation alone (n = 30) or 2 Gy total body irradiation preceded by fludarabine 30 mg/m(2)/d on days -4, -3, and -2 (n = 10). All received postgrafting mycophenolate mofetil and cyclosporine. Controls included 67 concurrent patients, aged 23 to 66 years (median, 46 years), given conventional PBSC transplants following high-dose conditioning and postgrafting methotrexate and cyclosporine. Among patients given nonmyeloablative transplants, 23% required platelet transfusions compared with 100% among patients given conventional grafts (P <.0001). Further, the number of platelet units given to nonmyeloablative recipients was reduced, with a median of 0 (range, 0 to 214) compared with a median of 24 (range, 4 to 358) after conventional transplantation (P <.0001). Sixty-three percent of nonmyeloablative recipients required RBC transfusions compared with 96% of those with conventional grafts (P =.0001). The number of RBC units transfused was also reduced, with a median of 2 (range, 0 to 50) compared with 6 (range, 0 to 34) after conventional transplantation (P =.0001). High transfusion requirements before transplantation and donor-recipient ABO incompatibility increased transfusion requirements in both patient groups, though neither significantly influenced the outcome of the analysis. Neither patient age, splenomegaly at transplantation, development of graft-versus-host disease, nor posttransplantation cytomegalovirus antigenemia or cytomegalovirus disease had statistically significant influences on posttransplantation transfusions.
Awareness of Lifestyle and Colorectal Cancer Risk: Findings from the BeWEL Study

It is estimated that 47% of colorectal cancers (CRC) could be prevented by appropriate lifestyles. This study aimed to identify awareness of the causes of CRC in patients who had been diagnosed with a colorectal adenoma through the Scottish Bowel Screening Programme and subsequently enrolled in an intervention trial (using diet and physical activity education and behavioural change techniques) (BeWEL). At baseline and 12-month follow-up, participants answered an open-ended question on factors influencing CRC development. Of the 329 participants at baseline, 40 (12%) reported that they did not know any risk factors and 36 (11%) failed to identify specific factors related to diet and activity. From a potential knowledge score of 1 to 6, the mean score was 1.5 (SD 1.1, range 0 to 5) with no difference between intervention and control groups. At follow-up, the intervention group had a significantly greater knowledge score and better weight loss, diet, and physical activity measures than the control group. Awareness of relevant lifestyle factors for CRC remains low in people at increased risk of the disease. Opportunities within routine NHS screening to aid the capability (including knowledge of risk factors) of individuals to make behavioural changes to reduce CRC risk deserve exploration.
Outcomes after thyroidectomy and parathyroidectomy.

Previous reports on postoperative outcomes following thyroid and parathyroid surgery are limited by relatively small sample size. We report 30-day outcomes following thyroid and parathyroid surgery and analyze factors affecting length of stay (LOS) and postoperative adverse events (AEs).



The multicenter, prospective, National Surgical Quality Improvement Program (NSQIP) datasets (2007/2008) were used. Multivariable logistic regression and analysis of covariance (ANCOVA) were performed.



Patients undergoing thyroidectomy, parathyroidectomy, or both were identified (n = 13,380, 6154, 1535, respectively). Thirty-day mortality was 0.08%, 0.16%, and 0.2%, respectively; 30-day morbidity was 3.50%, 3.02%, and 4.04%, respectively. Mean LOS values were 1.1 ± 1.4, 1.1 ± 2.1, and 1.4 ± 3.1 days, respectively. Congestive heart failure, dependent functional status, dialysis dependence, and chronic corticosteroid use were significantly associated with increased LOS and postoperative AE.



Morbidity and mortality rates following thyroid and parathyroid surgery are low. These data could be used by third-party interests, and surgeons should be aware of them to ensure their outcomes are in the national norm.
Associations of gestational glycemia and prepregnancy adiposity with offspring growth and adiposity in an Asian population.

Maternal obesity and hyperglycemia increase risk of obesity and diabetes in offspring later in life.



We examined the relation between gestational glycemia and prepregnancy body mass index (ppBMI) with offspring growth in an Asian mother-offspring cohort.



Pregnant mothers undertook a 75-g 2-h oral-glucose-tolerance test at 26-28 wk of gestation. In 937 singleton offspring, ≤9 serial measurements of weight and length were obtained from birth until 36 mo of age.



Gestational fasting plasma glucose (FPG) was positively associated with birth weight (B: 0.17; 95% CI: 0.10, 0.24; P < 0.001) and birth BMI (B: 0.15; 95% CI: 0.06, 0.40; P = 0.001) but not at ≥3 mo of age. In contrast, maternal ppBMI was positively associated with birth variables and conditional growth in weight and BMI in the first 36 mo of life. However, gestational FPG and prepregnancy obesity status interacted significantly for the association with offspring growth and overweight status in the first 36 mo of life (P-interaction < 0.01). In nonobese mothers, each unit increase in gestational FPG was associated with increased offspring weight (B: 0.08; 95% CI: 0.008, 0.16; P = 0.03) and BMI (B: 0.08; 95% CI: 0.003, 0.15; P = 0.04) as well as increased risk of overweight in the first 36 mo of life (OR: 1.36; 95% CI: 1.10, 1.68). However, in obese mothers, each unit increase in gestational FPG was associated with decreased offspring weight (B: -0.01; 95% CI: -0.02, -0.003) and BMI (B: -0.008; 95% CI: -0.01, -0.002) velocity (P < 0.01 for both) and decreased risk of overweight (OR: 0.59; 95% CI: 0.41, 0.86) in the first 36 mo of life.



Prepregnancy adiposity was associated with offspring growth in early childhood. Although pooled analyses showed no demonstrable difference by 3 mo of age, there were contrasting and opposite associations of gestational glycemia with weight and BMI in the first 36 mo of life in offspring of nonobese and obese mothers separately.
Time to initiation of treatment with polymyxin B cartridge hemoperfusion in septic shock patients.

We investigated whether early initiation of hemoperfusion with a polymyxin B cartridge (PMX) after the diagnosis of septic shock could improve the clinical outcome.



A prospective, open-labeled, multicenter cohort study was performed at intensive care units in Japan. 41 patients received PMX within 6 h after the diagnosis of septic shock (early group) and 51 patients were treated after 6 h (late group).



The early group had a significantly shorter duration of ventilator support and also had a lower catecholamine requirement. PMX was effective for improvement of hypotension, hypoperfusion, the sequential organ failure assessment score, and pulmonary oxygenation regardless of the timing of its initiation. The 28-day mortality rate did not differ between the two groups.



Early initiation of PMX shortened the duration of ventilator support and also reduced the catecholamine requirement, so early treatment of septic shock should achieve a better outcome.
Initial clinical validation of Health Heritage, a patient-facing tool for personal and family history collection and cancer risk assessment

Personal and family health histories remain important independent risk factors for cancer; however they are currently not being well collected or used effectively. Health Heritage was designed to address this need. The purpose of this study was to validate the ability of Health Heritage to identify patients appropriate for further genetic evaluation and to accurately stratify cancer risk. A retrospective chart review was conducted on 100 random patients seen at an adult genetics clinic presenting with concern for an inherited predisposition to cancer. Relevant personal and family history obtained from the patients’ medical records was entered into Health Heritage. Recommendations by Health Heritage were compared to national guidelines of eligibility for genetic evaluation. Agreement between Health Heritage referral for genetic evaluation and guideline eligibility for genetic evaluation was 97 % (sensitivity 98 % and specificity 88 %). Risk stratification for cancer was also compared between Health Heritage and those documented by a geneticist. For patients at increased risk for breast, ovarian, or colorectal cancer as determined by the geneticist, risk stratification by Health Heritage agreed 90, 93, and 75 %, respectively. Discordances in risk stratification were attributed to both complex situations better handled by the geneticist and Health Heritage’s adherence to incorporating all information into its algorithms. Health Heritage is a clinically valid tool to identify patients appropriate for further genetic evaluation and to encourage them to confirm the assessment and management recommendations with cancer genetic experts. Health Heritage also provides an estimate of cancer risk that is complementary to a genetics team.
Screening for type 2 diabetes is feasible, acceptable, but associated with increased short-term anxiety: A randomised controlled trial in British general practice

To assess the feasibility and uptake of a diabetes screening programme; to examine the effects of invitation to diabetes screening on anxiety, self-rated health and illness perceptions.



Randomised controlled trial in two general practices in Cambridgeshire. Individuals aged 40-69 without known diabetes were identified as being at high risk of having undiagnosed type 2 diabetes using patient records and a validated risk score (n = 1,280). 355 individuals were randomised in a 2 to 1 ratio into non-invited (n = 238) and invited (n = 116) groups. A stepwise screening programme confirmed the presence or absence of diabetes. Six weeks after the last contact (either test or invitation), a questionnaire was sent to all participants, including non-attenders and those who were not originally invited. Outcome measures included attendance, anxiety (short-form Spielberger State Anxiety Inventory-STAI), self-rated health and diabetes illness perceptions.



95 people (82% of those invited) attended for the initial capillary blood test. Six individuals were diagnosed with diabetes. Invited participants were more anxious than those not invited (37.6 vs. 34.1 STAI, p-value = 0.015), and those diagnosed with diabetes were considerably more anxious than those classified free of diabetes (46.7 vs. 37.0 STAI, p-value = 0.031). Non-attenders had a higher mean treatment control sub-scale (3.87 vs. 3.56, p-value = 0.016) and a lower mean emotional representation sub-scale (1.81 vs. 2.68, p-value = 0.001) than attenders. No differences in the other five illness perception sub-scales or self-rated health were found.



Screening for type 2 diabetes in primary care is feasible but may be associated with higher levels of short-term anxiety among invited compared with non-invited participants.
Retreatment With Varenicline for Smoking Cessation in Smokers Who Have Previously Taken Varenicline: A Randomized, Placebo-Controlled Trial

The efficacy and safety of retreatment with varenicline in smokers attempting to quit were evaluated in this randomized, double-blind, placebo-controlled, multicenter trial (Australia, Belgium, Canada, the Czech Republic, France, Germany, the United Kingdom, and the United States). Participants were generally healthy adult smokers (≥ 10 cigarettes/day) with ≥ 1 prior quit attempt (≥ 2 weeks) using varenicline and no quit attempts in ≤ 3 months; they were randomly assigned (1:1) to 12 weeks' varenicline (n = 251) or placebo (n = 247) treatment, with individual counseling, plus 40 weeks' nontreatment follow-up. The primary efficacy end point was the carbon monoxide-confirmed (≤ 10 ppm) continuous abstinence rate for weeks 9-12, which was 45.0% (varenicline; n = 249) vs. 11.8% (placebo; n = 245; odds ratio: 7.08; 95% confidence interval: 4.34, 11.55; P < 0.0001). Common varenicline group adverse events were nausea, abnormal dreams, and headache, with no reported suicidal behavior. Varenicline is efficacious and well tolerated in smokers who have previously taken it. Abstinence rates are comparable with rates reported for varenicline-naive smokers.
High level of plasma remnant-like particle cholesterol may predispose to development of hypertension in normotensive subjects.

Remnant-like lipoprotein particle cholesterol (RLP-C) is a highly atherogenic factor. RLP-C induces endothelial dysfunction and is associated with hyperinsulinemia. This study was designed to determine whether high plasma RLP-C levels predispose to the development of hypertension in subjects with normal blood pressure (BP).



A total of 1,485 subjects aged >40 years in a Japanese Cohort of the Seven Countries Study received health examinations. We examined BP, anthropometric parameters, and blood chemistries, including fasting RLP-C levels. RLP-C levels were measured by an immune-separation method. We excluded from the analysis 676 subjects who had hypertension (BP ≥ 140/90mm Hg), or were on antihypertensive medication, and/or were on antihyperlipidemic medication at baseline. Ten years later, 681 subjects were re-examined.



Of 681 normotensive subjects at baseline, 303 subjects had developed hypertension 10 years later. Baseline RLP-C level was significantly higher (P < 0.01) in the subjects who developed hypertension than in those who remained normotensive (3.7±1.9 vs. 3.3±1.6mg/dl). Multivariable logistic regression analysis demonstrated that baseline RLP-C was a significant factor for incident hypertension after adjustments for homeostasis model assessment index and other hypertension-related factors (odds ratio = 1.05, 95% CI = 1.00-1.10; P = 0.04).



A high level of plasma RLP-C in normotensive subjects may predispose to the development of hypertension in a population of community-dwelling Japanese.
The relationship between the androgen receptor CAG repeat polymorphism length and the response to intermittent androgen suppression therapy for advanced prostate cancer

To determine whether the duration of the off-treatment interval in patients being treated with intermittent androgen deprivation therapy can be predicted by the length of the CAG trinucleotide repeat polymorphism in the androgen receptor.This is a companion study to a prospective randomized trial, NCIC CTG PR-7, comparing intermittent to continuous androgen deprivation therapy in men with PSA progression after radiation therapy. The duration of the first off-treatment interval was established for 76 participants randomized to the intermittent therapy arm of the trial. Androgen receptor CAG repeat polymorphism lengths were determined for these 76 participants. Statistical analysis was completed to determine a relationship between CAG repeat length and the duration of the off-treatment interval.A significant correlation was not established (P=0.424) between androgen receptor CAG repeat length and the duration of the first off-treatment interval. Categorical analysis of CAG repeat lengths using 18 and 22 as cutoff points did not find any significant difference in the mean duration of the off-treatment interval between categories (P=0.672 and 0.774, respectively).Conclusion:No relationship was established between the duration of the first off-treatment interval and the CAG repeat length.
Detection of new human metabolic urinary markers in chronic alcoholism and their reversal by aqueous extract of Tinospora cordifolia stem.

We have studied urine metabolic signature of chronic alcoholism (CA) before and after treatment with an Ayurvedic drug Tinospora cordifolia aqueous extract (TCE).



Urinary metabolites of chronic alcoholics and apparently healthy subjects were profiled using HPLC-Q-TOF-MS. Discrimination models from the initial data sets were able to correctly assign the unknown samples to the CA, treated or healthy groups in validation sets with r(2) > 0.98.



Metabolic signature in CA patients include changed tryptophan, fatty acids and pyrimidines metabolism. Several novel biomarkers of alcoholism were observed in urine for the first time which includes, 5-hydroxyindole, phenylacetic acid, picolinic acid, quinaldic acid, histidine, cystathionine, riboflavin, tetrahydrobiopterin and chenodeoxyglycocholic acid, in addition to previously reported biomarkers. Treatment of CA with TCE reverted the levels of most of the biomarkers except tetrahydrobiopterin levels.



These results suggested that the measurement of these urine metabolites could be used as a non-invasive diagnostic method for the detection of CA. As TCE treatment significantly reversed the affected pathways without any side effect. Overall, the present data depicts that TCE may be used either alone or adjunct in reducing alcohol-induced disorders.
Laparoscopic versus open surgery for extraperitoneal rectal cancer: a prospective comparative study

The role of laparoscopic resection (LR) in the management of extraperitoneal rectal cancer still is unclear. This study aimed to compare perioperative and long-term results of laparoscopic and open resection (OR) for low and midrectal cancer. A prospective nonrandomized trial comparing patients submitted to OR or LR for low and midrectal cancer at a single institution was conducted. The study included 191 consecutive patients: 98 patients who underwent LR and 93 who underwent OR. The mean follow-up period was 46.3 months for LR and 49.7 months for OR. The conversion rate for LR was 18.4%. With the use of LR, the mean time for complete patient mobilization was shorter (1.7 vs 3.3 days; p < 0.001) and patients were earlier in passing flatus (2.6 vs 3.9 days; p < 0.001) and stools (3.8 vs 4.7 days; p < 0.01), and in resuming oral intake (3.4 vs 4.8 days; p < 0.001). The mean hospital stay was shorter for LR, but the difference did not reach significance (11.4 vs 13 days). Morbidity and mortality rates were similar: LR (24.4% and 1%) and OR (23.6% and 2.2%). Laparoscopic patients presented a higher rate of anastomotic fistulas (13.5% vs 5.1%) and reoperations (6.1% vs 3.2%) but the difference was statistically nonsignificant. Laparoscopic resection presented a significantly lower local recurrence rate (3.2% vs 12.6%; p < 0.05). The cumulative survival and disease-free rates at 5 years were, respectively, 80% and 65.4% after LR and 68.9% and 58.9% after OR (nonsignificant difference). Stage-by-stage comparison showed prolonged cumulative survival for stages III and IV cancer in LR (82.5% vs 40.5%; p = 0.006 and 15.8% vs 0%; p = 0.013, respectively) and a reduced rate of cancer-related death for stage III in LR (11.4% vs 51.9%; p = 0.001). As compared with conventional open surgery, LR for low and midrectal cancer is characterized by a faster recovery and similar overall morbidity (but a higher rate of anastomotic leakages), and does not present any adverse oncologic effect.
Quantification of Adequate Bowel Preparation for Screening or Surveillance Colonoscopy in Men.

Bowel preparation is defined as adequate if it is sufficient for identification of polyps greater than 5 mm. However, adequate preparation has not been quantified. We performed a prospective observational study to provide an objective definition of adequate preparation, based on the Boston Bowel Prep Scale (BBPS, which consists of 0-3 points for each of 3 colon segments).



We collected data from 438 men who underwent screening or surveillance colonoscopies and then repeat colonoscopy examinations within 60 days by a different blinded endoscopist (1161 colon segments total) at the West Haven Veterans Affairs Medical Center from January 2014 to February 2015. Missed polyps were defined as those detected on the second examination of patients with the best possible bowel preparation (colon segment BBPS score of 3) on the second examination. The primary outcome was the proportion of colon segments with adenomas larger than 5 mm that were missed in the first examination. We postulated that the miss rate was noninferior for segments with BBPS scores of 2 vs those with BBPS scores of 3 (noninferiority margin, <5%). Our secondary hypotheses were that miss rates were higher in segments with BBPS scores of 1 vs those with scores of 3 or of 2.



The adjusted proportion with missed adenomas greater than 5 mm was noninferior for segments with BBPS scores of 2 (5.2%) vs those with BBPS scores of 3 (5.6%) (a difference of -0.4%; 95% confidence interval [CI], -2.9% to 2.2%). Of study subjects, 347 (79.2%) had BBPS scores of 2 or greater in all segments on the initial examination. A higher proportion of segments with BBPS scores of 1 had missed adenomas larger than 5 mm (15.9%) than segments with BBPS scores of 3 (5.6%) (a difference of 10.3%; 95% CI, 2.7%-17.9%) or 2 (5.2%) (a difference of 10.7%; 95% CI, 3.2%-18.1%). Screening and surveillance intervals based solely on the findings at the first examination would have been incorrect for 16.3% of patients with BBPS scores of 3 in all segments, for 15.3% with BBPS scores of 2 or 3 in all segments, and for 43.5% of patients with a BBPS score of 1 in 1 or more segments.



Patients with BBPS scores of 2 or 3 for all colon segments have adequate bowel preparation for the detection of adenomas larger than 5 mm and should return for screening or surveillance colonoscopy at standard guideline-recommended intervals. Colon segments with a BBPS score of 1 have a significantly higher rate of missed adenomas larger than 5 mm than segments with scores of 2 or 3. This finding supports a recommendation for early repeat colonoscopic evaluation in patients with a BBPS score of 0 or 1 in any colon segment.
