Pretreatment Lifestyle Behaviors as Survival Predictors for Patients with Nasopharyngeal Carcinoma

Lifestyle behaviors have been widely reported to influence the survival of patients with head and neck cancer. However, the relationship between pretreatment lifestyle behaviors and survival among patients with nasopharyngeal carcinoma (NPC) is unclear.



A prospective cohort study was designed to determine the relationship between lifestyle behaviors and survival in 1,533 NPC patients recruited from October 2005 to October 2007. Pretreatment lifestyle behaviors (such as body-mass index [BMI], smoking, alcohol, diet) of the patients were investigated. Univariate and multivariate proportional-hazards models were used to assess the impact of lifestyle behaviors on patient survival.



Smoking was a predictor of survival; both current smokers (hazard ratio [HR] = 1.88; 95% CI, 1.33 to 2.65) and heavy smokers (≥ 25 Pack-years; HR = 1.84; 95% CI, 1.30 to 2.60) showed associations with poor survival. Higher BMI was significantly associated with a lower risk of death (P(trend) = 0.002). Compared with under/normal-weight patients (BMI less than 22.99 kg/m(2)), the multivariate HR for survival was 0.66 (95% CI, 0.48 to 0.90) and 0.47 (95% CI, 0.23 to 0.97) for overweight and obese patients, respectively. No alcohol intake and high fruit intake were associated with favorable survival in the univariate analysis but lost significance in the multivariate model.



Our findings indicate that pretreatment lifestyle behaviors, especially smoking status and BMI, as easily available data, provide prognostic value for survival in NPC patients.
Tissue expansion in the treatment of giant congenital melanocytic nevi of the upper extremity

The aim of our study was to use tissue expansion for the treatment of giant congenital melanocytic nevi of the upper extremity and examine potential advantages over traditional techniques.There were 3 stages in the treatment of giant congenital melanocytic nevi of the upper extremities using tissue expansion: first, the expander was inserted into the subcutaneous pocket; second, the expander was removed, lesions were excised, and the wound of the upper extremity was placed into the pocket to delay healing; third, the residual lesion was excised and the pedicle was removed. The pedicle flap was then unfolded to resurface the wound.During the period between June 2007 and December 2015, there were 11 patients with giant congenital melanocytic nevi of the upper extremities who underwent reconstruction at our department with skin expansion. Few complications were noted in each stage of treatment. The functional and aesthetic results were observed and discussed in this study.Optimal aesthetic and functional results were obtained using tissue expansion to reconstruct the upper extremities due to the giant congenital melanocytic nevi.
The value of TOP2A gene copy number variation as a biomarker in breast cancer: Update of DBCG trial 89D.

Previous analyses of TOP2A and HER2 in the Danish Breast Cancer Coopererative Group (DBCG) trial 89D suggested that TOP2A amplifications and possible also deletions are predictive markers for the effect of adjuvant epirubicin in patients with primary breast cancer. We present an updated and extended statistical analysis, requested for IVD-labeling of TOP2A testing.



In the DBCG trial 89D 980 Danish patients were randomly assigned to nine cycles of intravenous CMF (cyclophosphamide, methotrexate, and fluorouracil) or CEF (cyclophosphamide, epirubicin, and fluorouracil). Archival tumor tissue was collected retrospectively from 806 of these patients in a prospectively designed, biological sub-study, and was successfully analyzed for TOP2A aberrations and HER2 status in 773 samples (96%). Recurrence-free survival (RFS) was the primary endpoint.



TOP2A aberrations (amplifications and deletions) were significantly associated with shorter RFS (p<0.0001) and overall survival (OS) (p<0.0001). Deleted cases had worse prognosis than amplified cases. In a Cox proportional hazard model TOP2A was an independent prognostic marker for RFS and OS. Patients with amplifications had a 61% reduction in the risk of an event (p=0.002) and a 51% reduction in the risk of death (p=0.01) if allocated to CEF compared to 6% and 10% in TOP2A normal patients. A similar but non-significant trend (p=0.08) was shown in patients with TOP2A deletions. Clear statistical evidence of a differential benefit, favoring CEF among patients with TOP2A aberrations was found for RFS (p=0.02 for interaction) but not for OS (p=0.14 for interaction).



In conclusion, this updated analysis of TOP2A aberrations in DBCG trial 89D suggests a differential benefit of adjuvant chemotherapy in patients with primary breast cancer, favoring treatment with epirubicin in patients with TOP2A amplifications, and perhaps deletions. Additional studies are needed to clarify the exact importance of TOP2A deletions on outcome, but deletions have proven to be associated with a very poor prognosis.
Effects of exercise training on conduit and resistance vessel function in treated and untreated hypercholesterolaemic subjects.

Despite the importance of both lipid metabolism and physical activity to cardiovascular health, few studies have examined the effect of exercise training on vascular function in hypercholesterolaemic humans.



A randomized, cross-over design investigated the effect of 8 weeks of combined aerobic and resistance exercise training on conduit and resistance vessel function in 11 untreated subjects with hypercholesterolaemia and 11 subjects taking lipid-lowering medication. High-resolution vascular ultrasonography following forearm ischaemia and glyceryl trinitrate administration determined conduit vessel endothelium-dependent and independent function. Strain-gauge plethysmography, with intra-aerial infusions of acetylcholine, sodium nitroprusside and N(G)-monomethyl-L-arginine, determined resistance vessel function. Flow-mediated dilation and the forearm blood flow response to acetylcholine improved significantly following training in the treated subgroup (both P<0.05) but not the untreated, although the blood flow response to N(G)-monomethyl-L-arginine was augmented following training in the untreated subjects (P<0.05), indicating greater basal nitric oxide bioactivity. Training did not alter responsiveness to glyceryl trinitrate or sodium nitroprusside.



Combined aerobic and resistance training improves endothelium-dependent conduit and resistance vessel function in hypercholesterolaemic subjects taking lipid-lowering medications and basal nitric oxide bioactivity in untreated hypercholesterolaemic subjects. Exercise training may provide additional cardiovascular benefits for hypercholesterolaemic patients including those taking lipid-lowering medication.
The effect of renal denervation added to standard pharmacologic treatment versus standard pharmacologic treatment alone in patients with resistant hypertension: rationale and design of the SYMPATHY trial.

The first studies on renal denervation (RDN) suggest that this treatment is feasible, effective, and safe in the short term. Presently available data are promising, but important uncertainties exist; therefore, SYMPATHY has been initiated. SYMPATHY is a multicenter, randomized, controlled trial in patients randomized to RDN in addition to usual care (intervention group) or to continued usual care (control group). Randomization will take place in a ratio of 2 to 1. At least 300 participants will be included to answer the primary objective. Sample size may be extended to a maximum of 570 to address key secondary objectives. The primary objective is to assess whether RDN added to usual care compared with usual care alone reduces blood pressure (BP) (ambulatory daytime systolic BP) in subjects with an average daytime systolic BP ≥135, despite use of ≥3 BP-lowering agents, 6 months after RDN. Key secondary objectives are evaluated at 6 months and at regular intervals during continued follow-up and include the effect of RDN on the use of BP-lowering agents, in different subgroups (across strata of estimated glomerular filtration rate and of baseline BP), on office BP, quality of life, and cost-effectiveness.
Disassociation between risk of graft loss and risk of non-Hodgkin lymphoma with induction agents in renal transplant recipients.

It is widely assumed that the graft-enhancing properties of antilymphocyte induction agents and their lymphoma-inducing potential are intimately related.



The Collaborative Transplant Study (CTS) database was used to evaluate graft survival and non-Hodgkin lymphoma at 3 years according to type of induction in 112,122 patients receiving a deceased-donor renal transplant during 1985 to 2004.



The relative risk of 3-year graft loss versus no induction was 1.07 (95% confidence interval [CI], 1.01-1.13; P=0.016) with murine anti-CD3 monoclonal antibody (OKT3), 1.03 (95% CI, 0.95-1.11; NS) with antithymocyte globulin (ATG)-Fresenius, 1.18 (95% CI, 1.02-1.35; P=0.021) with ATGAM, 0.74 (95% CI, 0.68-0.81; P<0.001) with Thymoglobulin, and 0.78 (95% CI, 0.72-0.84; P<0.001) with interleukin (IL)-2RA induction. The standardized incidence ratio of lymphoma compared with a similar nontransplant population was 21.5 (95% CI, 15.7-28.8; P<0.001) with OKT3, 4.9 (95% CI, 1.6-11.5; P=0.008) with ATG-Fresenius, 29.0 (95% CI, 12.5-57.1; P<0.001) with ATGAM, 21.6 (95% CI, 14.3-31.2; P<0.001) with Thymoglobulin, 7.8 (95% CI, 4.4-12.9; P<0.001) with IL-2RAs, and 9.4 (95% CI, 8.3-10.6 P<0.001) with no induction.



Those agents that offered the highest rates of graft survival were not necessarily associated with the highest risk of lymphoma. Graft survival was significantly improved with Thymoglobulin and IL-2RA induction, whereas lymphoma rates were highest with ATGAM, OKT3, and Thymoglobulin. IL-2RA agents seem to offer the best risk-to-benefit ratio for this patient population overall in terms of graft survival and lymphoma.
Impact of combined lipid lowering with blood pressure control on coronary plaque regression: rationale and design of MILLION study

A line of epidemiological studies suggests that the accumulation of coronary risk factors promotes the progression of coronary atherosclerosis. Recent clinical studies showed that aggressive low-density lipoprotein (LDL) cholesterol-lowering therapy using statins could regress coronary atheroma and reduce major cardiovascular events. Additionally, therapy that controlled amlodipine-based blood pressure reduced major cardiovascular events in patients with hypertension compared with an atenolol-based regimen. An open-label randomized multicenter study is primarily planned to evaluate the changes in coronary atheroma volume using intravascular ultrasonography 18–24 months after intensive lowering of LDL-cholesterol and blood pressure compared with a standard therapy indicated by current guidelines in Japanese patients with coronary artery disease (CAD). The secondary endpoints include changes in serum lipid levels, inflammatory markers, glucose markers and blood pressure. In total, 100 subjects with CAD who are undergoing percutaneous coronary intervention will be tested. The MILLION study will provide new evidence and therapeutic standards for the prevention of CAD in Japanese patients by controlling both LDL-C levels and blood pressure.
Using an informed consent in mammography screening: a randomized trial

Spanish women do not make an informed choice regarding breast cancer screening (BCS). Our aim was to evaluate the impact of receiving information regarding real BCS benefits and risks on knowledge, attitude, decision, feelings, and worries about cancer. Randomized controlled clinical trial of 355 women aged between 45 and 67 years, 177 and 178 assigned to the intervention group (IG) and control group (CG), respectively. After breast screening, women received either Nordic Cochrane Centre information on BCS or standard information. The primary outcome (knowledge) was determined from questionnaire administered at baseline and after a month. Answers were scored from 0 to 10 and scores of 5 or more indicated that women were well informed (had "good knowledge"). Questionnaires regarding attitudes, future screening intentions, and psychosocial impact were also administered. The Chi-squared and Student's t-tests were used to compare qualitative and quantitative variables, respectively. Good knowledge was acquired by 32 (18.10%) IG women and 15 (8.40%) CG women (P = 0.008). Mean scores from first to second interview increased from 2.97 (SD 1.16) to 3.43 (SD 1.39) in the CG and from and from 2.96 (SD 1.23) to 3.95 (SD 1.78) (P = 0.002) in the IG. No differences were found in the secondary endpoints. Women receiving information based on the Nordic Cochrane Centre document were better informed. This means of providing information is not very efficacious, nor does it modify attitude, decision, feelings, or worries about cancer.
The human figure drawing as related to attention-deficit hyperactivity disorder (ADHD).

To assess the reliability and validity of the human figure drawing test among children with attention-deficit hyperactivity disorder (ADHD) and/or learning disability, boys (n = 136) between the ages of 8 and 10 years, with either or both ADHD and learning disability, were included. Two drawings were used: person and house, tree and person. The drawings were analyzed using the Koppitz emotional and developmental scales. Conners teacher and parent rating scales and the Matching Familiar Figure Test were administered. High intertest reliability for the emotional scale and a significant negative correlation between the 2 scales were found. The reported anxiety and learning were significantly correlated with the cognitive score. A combination of cognitive and emotional items resulted in 67% correct classification of ADHD and learning disability. This test can be used as part of the assessment of ADHD/learning disability.
Aerobic fitness levels and validation of a non exercise VO2max prediction equation for HIV-infected patients on HAART.

Non-exercise (N-EX) questionnaires have been developed to determine maximal oxygen consumption (VO2max) in healthy populations. There are limited reliable and validated N-EX questionnaires for the HIV+ population that provide estimates of habitual physical activity and not VO2max.



To determine how well regression equations developed previously on healthy populations, including N-EX prediction equations for VO2max and age-predicted maximal heart rates (APMHR), worked on an HIV+ population; and to develop a specific N-EX prediction equation for VO2max and APMHR for HIV+ individuals.



Sixty-six HIV+ participants on stable HAART completed 4 N-EX questionnaires and performed a maximal graded exercise test.



Sixty males and 6 females were included; mean (SD) age was 49.2 (8.2) years; CD4 count was 516.0 ± 253.0 cells·mm-3; and 92% had undetectable HIV PCR. Mean VO2max was 29.2 ± 7.6 (range, 14.4-49.4) mL·kg-1·min-1 Despite positive correlations with VO2max, previously published N-EX VO2max equations produced results significantly different than actual VO2 scores (P < .0001). An HIV+ specific N-EX equation was developed and produced similar mean VO2max values, R = 0.71, when compared to achieved VO2max (P = .53).



HIV+ individuals tend to be sedentary and unfit, putting them at increased risk for the development of chronic diseases associated with a sedentary lifestyle. Based on the level of error associated with utilizing APMHR and N-EX VO2max equations with HIV+ individuals, neither should be used in this population for exercise prescription.
Mood reactivity rather than cognitive reactivity is predictive of depressive relapse: a randomized study with 5.5-year follow-up.

The current study examined whether cognitive reactivity, cognitive extremity reactivity, and mood reactivity following mood provocation predicted relapse in depression over 5.5 years. Additionally, this study was the 1st to examine whether changes in cognitive reactivity and mood reactivity following preventive cognitive therapy (PCT) mediated the preventive effect of PCT on relapse.



One hundred eighty-seven remitted recurrently depressed outpatients were randomized over treatment as usual (TAU) versus TAU + PCT with 5.5-year follow-up. Relapse in depression was assessed with the Structured Clinical Interview for DSM-IV Axis I Disorders (Spitzer, Williams, Gibbon, & First, 1990).



Mood reactivity predicted time to relapse over 5.5 years. We found no evidence that cognitive reactivity was a risk factor for relapse in depression. Moreover, unprimed dysfunctional beliefs predicted relapse directly. There was no indication of mediation by changes in cognitive reactivity (including extremity of the beliefs and unprimed beliefs) or mood reactivity on the preventive effect of PCT. Further, explorative analyses revealed that increases in cognitive and mood reactivity over time also predicted time to relapse.



Our findings highlight a need to focus on mood reactivity instead of beliefs as a risk factor for relapse in depression. Similar to a previous study, we found no indications that cognitive therapy after remission reduced dysfunctional beliefs, cognitive reactivity, or extremity. Future studies should examine cognitive reactivity and mood reactivity in daily life as predictors of relapse.
Prayer Sign as a Marker of Increased Ventilatory Hours, Length of Intensive Care Unit and Hospital Stay in Patients Undergoing Coronary Artery Bypass Grafting Surgery

Various predictors have been used to predict diabetic patients who are likely to have increased ventilatory hours and an increased length of stay (LOS) in the Intensive Care Unit (ICU) as well as in the hospital after undergoing coronary artery bypass grafting (CABG) surgery, for example, glycosylated hemoglobin (HbA1c). The authors propose a simple bed-side test, i.e., the prayer sign to predict increased ventilatory hours and increased length of ICU and hospital stay.



The aim of the present study was to assess whether any association exists between a positive prayer sign and increased ventilatory hours, length of ICU and hospital stay after CABG surgery in diabetic patients.



This prospective observational study was conducted in a 650-bedded tertiary cardiac center.



A total of 501 diabetic patients were recruited in the study over a period of 1 year. Group P consisted of 121 patients with prayer sign positive, whereas Group N consisted of 380 patients with prayer sign negative. HbA1c levels, ventilatory hours, LOS in the postoperative ICU and hospital were compared.


 USED
Unpaired Student's t-test was used to compare the data.



The mean HbA1c levels in Group P were 8.01 ± 2.28% as compared to 6.52 ± 2.46% in Group N (P < 0.0001). The mean ventilatory hours in Group P were 9.52 ± 6.46 h, and in Group N were 7.42 ± 8.01 h (P = 0.013). Whereas, the mean length of ICU stay and hospital stay in Group P was 156.42 ± 32.66 h (6.51 ± 1.36 days) and 197.36 ± 32.46 h (8.22 ± 1.35 days), respectively, it was 121.12 ± 29.48 h (5.04 ± 1.22 days) and 178.52 ± 28.52 h (7.43 ± 1.18 days) in Group N (P < 0.0001).



A positive prayer sign is a useful bedside test for predicting increased ventilatory hours and increased length of ICU and hospital stay after CABG surgery.
Evaluation of vulvovaginal symptoms and Candida colonization in women with type 2 diabetes mellitus treated with canagliflozin, a sodium glucose co-transporter 2 inhibitor.

Women with type 2 diabetes mellitus (T2DM) are at increased risk for vaginal Candida colonization, perhaps because of glucosuria. Sodium glucose co-transporter 2 (SGLT2) inhibitors, in development for the treatment of T2DM, improve glycemic control by increasing urinary glucose excretion. Vaginal Candida colonization and symptomatic vulvovaginal adverse events (VVAE) were assessed in females with T2DM treated with canagliflozin, a SGLT2 inhibitor.



In a double-blind study, subjects with T2DM and inadequate glycemic control on metformin were randomized to placebo; canagliflozin 50, 100, 200, 300 mg daily or 300 mg twice daily; or sitagliptin 100 mg daily for 12 weeks. Vaginal swabs for Candida culture were collected from 198 female subjects at baseline and week 12, and during the trial if symptoms consistent with vulvovaginal candidiasis occurred.



At baseline, 23/198 (12%) females had vaginal cultures positive for Candida (C. glabrata: 14; C. albicans: 5; other: 4), with age ≤55 years associated with increased risk (odds ratio [OR], 3.5; 95% confidence interval [CI], 1.1-10.7). Of those with negative cultures at baseline, 31% of canagliflozin and 14% of placebo/sitagliptin subjects converted to positive at week 12 (OR, 2.8; 95% CI, 1.0-7.3 for canagliflozin vs. placebo/sitagliptin). Two placebo/sitagliptin (3%) and 16 canagliflozin subjects (10%) experienced VVAE. Positive vaginal culture for Candida species at baseline was a risk factor for VVAE (OR, 9.1; 95% CI, 2.4-34.0). All 9/9 subjects in the canagliflozin group with a vaginal culture taken at the time of the VVAE were positive for Candida species. Most VVAE were treated with antifungal therapy and resolved without study drug interruption; none led to discontinuation. Study limitations include small population, short duration, and not obtaining cultures in all women with VVAE.



Canagliflozin treatment was associated with an increase in vaginal colonization with Candida species and in VVAE in women with T2DM.
Acceptability and effectiveness of a strategy for the communication of the diagnosis of psychogenic nonepileptic seizures.

Communicating the diagnosis of psychogenic nonepileptic seizures (PNES) is a challenging task. This study was carried out to assess the acceptability and effectiveness of a new communication procedure consisting of a patient information leaflet and a communication strategy for neurologists.



In a multicenter prospective study, 50 patients newly diagnosed with PNES were informed about the diagnosis by 10 different neurologists using the communication procedure. Follow-up data were gathered by telephone interview and completion of a questionnaire about symptom attributions (psychological/physical) and illness cognitions (Illness Perception Questionnaire-Revised, IPQ-R).



Ninety-four percent of patients found the leaflet easy to understand. Ninety-four percent stated their questions were answered by the doctor; 70% got what they wanted from the consultation; only 4% reported feeling angry during the consultation. Eighty-six percent of patients acknowledged that psychological factors were at least contributing to their seizures. On the IPQ-R, "emotional" causes for the seizures were endorsed more commonly than "nonemotional" causes (p < 0.001). After 3 months, 14% of patients were seizure-free and 63% reported a >50% reduction in seizure frequency.



We conclude that our procedure is acceptable and effectively communicates a psychological etiologic model for PNES.
Psychotherapy with traumatised refugees--the design of a randomised clinical trial.

There is little evidence as to which kind of psychotherapy is the most effective in the treatment of traumatised refugees. At the Competence Center for Transcultural Psychiatry, a series of clinical trials have been conducted since 2008. The first results are pending publication. The aim of this paper is to discuss some of the challenges in adapting Cognitive Behavioural Therapy (CBT) to the treatment of traumatised refugees, as well as describe a randomised clinical trial designed to test two such adaptations. In the described trial one group receives CBT with a focus on cognitive restructuring while the other group receives CBT focusing on Stress Management. A main goal of this setup is to test whether some, perhaps even most, of the traumatised refugees referred to treatment, may benefit from a more direct focus on current stress, and its alleviation through simple, repetitive exercises, compared to a focus on analysing and changing thought patterns.
