Differential Effects of Training in Relaxation and Stress-Coping in Patients with Migraine

SYNOPSIS
The effects of a psychophysiological treatment (relaxation training) and a psychological treatment(stress-coping training) were tested in 29 patients suffering from migraine.There were significant pre-post reductions in migraine variables and drug consumption. The effects didnot differ between the types of training, and remained stable for a medium-term follow-up of 8 months. Wethink, however, that stress-coping training may in course of time be superior in maintaining training gains.Although this assumption cannot yet be tested for longer follow-up periods, there was a non-significanttrend for stress-coping training to be more effective in migraine 8 months after training.There were different effects on social behavior: patients receiving relaxation training became moresocially withdrawn, while patients who underwent stress-coping training increased their socialassertiveness. Furthermore, according to the participants, relaxation training had a stronger impact onmigraine, whereas stress-coping training was more directed at migraine-related stress. However, pre-postcomparisons of the patients' coping with stress for the most part did not reveal significantly differenteffects between the two types of training.     

Long-Term Effects of Training in Relaxation and Stress-Coping in Patients with Migraine: A 3-Year Follow-Up

Research on the short-term effects of psychological interventions in migraine indicates improvement rates of 50 percent. Yet long-term follow-ups are scarce: the studies extending to three years provide evidence for the maintenance of effects, but these studies evaluate the benefits of rather complex psychological treatments and the samples include other types of headache. We compared the effects of single-method psychological interventions upon migraine. The study reports results obtained from 24 patients three years after completion of relaxation training, which is a psychophysiological regimen, and stress-coping training, which is a cognitive-behavioral regimen. Results for the complete sample, excluding data biased by confounding factors, provide clear evidence of the preservation of effects in migraine. Relaxation training (RT) and stress-coping training (SCT) were equally effective and both groups exhibited little medication consumption since completion of training. Among the secondary effects, SCT was found to improve assertiveness and active problem solving, and to decrease depressive reaction. The study yielded two predictor variables--little external stress for relaxation training, and high self motivation for stress-coping training--that accounted for more than 50 percent of the effect variance in the respective groups. Although more research is needed to substantiate our findings, the results suggest that, thus far, there is little reason to favor multimodal training or more complex psychological treatments over single-method psychological interventions in migraine. Also, our results do not support the assumed superiority of cognitive-behavioral treatment over psychophysiological treatment. Research on factors predicting long-term effects of psychological interventions in migraine may profit from considering separate variables on skill rehearsal and skill employment (instead of employing a global measure of home practice), and from a measure for post-training external stress.     

Validation of the Dutch Giving Youth a Voice Questionnaire (GYV-20): a measure of the client-centredness of rehabilitation services from an adolescent perspective

PURPOSE. The objective was to validate the Dutch translation of the Canadian Giving Youth a Voice Questionnaire (GYV-20) for use in paediatric rehabilitation settings in The Netherlands. The GYV-20 consists of 20 items (assessing four domains) and was designed to evaluate the client-centredness of rehabilitation services from an adolescent perspective. METHOD. The construct validity, concurrent validity, and reliability of the Dutch GYV-20 were determined. Participants were 116 youngsters aged 11 - 21 years (Mean = 15.9; SD = 2.1) recruited through six paediatric rehabilitation settings in The Netherlands. RESULTS. Correlations between the GYV-20 scale scores were positive (r = 0.69 - 0.78). The GYV-20 showed adequate internal consistency, with Cronbach's alpha ranging from 0.76 - 0.81. The ICCs of test-retest reliability ranged from 0.82 - 0.92, which demonstrated good stability of the GYV-20. Dutch adolescents judged the GYV-20 as a valuable and useful tool to evaluate rehabilitation services in The Netherlands. CONCLUSIONS. The Dutch GYV-20 showed sufficient evidence of construct validity and good reliabilities. The Dutch GYV-20 offers users a useful measurement option for various research and clinical purposes.     

Candidate colorectal cancer predisposing gene variants in Chinese early-onset and familial cases

AIM: To investigate whether whole-exome sequencing may serve as an efficient method to identify known or novel colorectal cancer(CRC) predisposing genes in early-onset or familial CRC cases.METHODS: We performed whole-exome sequencing in 23 Chinese patients from 21 families with nonpolyposis CRC diagnosed at ≤ 40 years of age, or from multiple affected CRC families with at least 1 firstdegree relative diagnosed with CRC at ≤ 55 years of age.Genomic DNA from blood was enriched for exome sequences using the Sure Select Human All Exon Kit, version 2(Agilent Technologies) and sequencing was performed on an Illumina Hi Seq 2000 platform.Data were processed through an analytical pipeline to search for rare germline variants in known or novel CRC predisposing genes.RESULTS: In total, 32 germline variants in 23 genes were identified and confirmed by Sanger sequencing.In 6 of the 21 families(29%), we identified 7 mutations in 3 known CRC predisposing genes including MLH1(5 patients), MSH2(1 patient), and MUTYH(biallelic, 1 patient), five of which were reported as pathogenic.Inthe remaining 15 families, we identified 20 rare and novel potentially deleterious variants in 19 genes, six of which were truncating mutations.One previously unreported variant identified in a conserved region of EIF2AK4(p.Glu738_Asp739insA rgA rg) was found to represent a local Chinese variant, which was significantly enriched in our early-onset CRC patient cohort compared to a control cohort of 100 healthy Chinese individuals scored negative by colonoscopy(33.3% vs 7%, P 0.001).CONCLUSION: Whole-exome sequencing of early-onset or familial CRC cases serves as an efficient method to identify known and potential pathogenic variants in established and novel candidate CRC predisposing genes.     

Most Patients with Colorectal Tumors at Young Age Do Not Visit a Cancer Genetics Clinic

Purpose  This study examined the referral process for genetic counseling at a cancer genetics clinic in patients with colorectal cancer and to search for determinants of variation in this referral process. Methods  Patients who were recently diagnosed with colorectal cancer at a young age or multiple cancers associated with Lynch syndrome, hereditary nonpolyposis colorectal cancer, (N = 119) were selected from PALGA, the nationwide network and registry of histopathology and cytopathology in the Netherlands. In a retrospective analysis, we examined whether these patients visited a cancer genetics clinic and identified determinants for referral to such a clinic. Factors of patients, professional practice, and hospital setting were explored with logistic regression modeling. Results  Thirty-six (30 percent) patients visited a cancer genetics clinic. Seventy percent of patients whom the surgeon referred to a cancer genetics clinic decided to visit such a clinic. Analysis of determinants showed that patients with whom the surgeon discussed referral and that were treated in a teaching hospital were more likely to visit a cancer genetics clinic. Conclusion  The referral process is not optimally carried out. To deliver optimal care for patients suspected of hereditary colorectal cancer, this process must be improved with interventions focusing on patient referral by surgeons and raising awareness in nonteaching hospitals.

Low but Sufficient Anidulafungin Exposure in Critically Ill Patients

The efficacy of anidulafungin is driven by the area under the concentration-time curve (AUC)/MIC ratio. Patients in intensive care may be at risk for underexposure. In critically ill patients with an invasive Candida infection, the anidulafungin exposure and a possible correlation with disease severity or plasma protein levels were explored. Concentration-time curves were therefore obtained at steady state. Anidulafungin concentrations were measured with a validated liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. The MIC values of the Candida species were determined with the Etest. The target AUC/MIC ratio was based on European Committee on Antimicrobial Susceptibility Testing (EUCAST) data. Twenty patients were included. The patients received a maintenance dose of 100 mg once daily after a loading dose of 200 mg on the first day. The mean (±standard deviation) AUC, maximum concentration of drug in plasma (C_max), and minimum concentration of drug in plasma (C_min) were 69.8 ± 24.1 mg · h/liter, 4.7 ± 1.4 mg/liter, and 2.2 ± 0.8 mg/liter, respectively. The MIC values of all cultured Candida species were below the EUCAST MIC breakpoints. The exposure to anidulafungin in relation to the MIC that was determined appeared sufficient in all patients. The anidulafungin exposure was low in our critically ill patients. However, combined with the low MICs of the isolated Candida strains, the lower exposure observed in comparison to the exposure in the general patient population resulted in favorable AUC/MIC ratios, based on EUCAST data. No correlation was observed between anidulafungin exposure and disease severity or plasma protein concentrations. In patients with less-susceptible Candida albicans or glabrata strains, we recommend considering determining the anidulafungin exposure to ensure adequate exposure.

Carcinoid crisis after injection of 6-18F-fluorodihydroxyphenylalanine in a patient with metastatic carcinoid.

A carcinoid crisis is a severe complication of the carcinoid syndrome that can arise in patients with advanced metastatic neuroendocrine tumors. It can be initiated by stress, catecholamines, and tumor manipulation. In this article, we report a case in which an injection with the catecholamine tracer 6-18F-fluorodihydroxyphenylalanine, used for PET, induced a carcinoid crisis. Octreotide can be used for treatment and should be available. Tracer injection should be slow.     

Influence of oral contraceptive pills on phenotype expression in women with polycystic ovary syndrome

Polycystic ovarian syndrome (PCOS) is characterized by a heterogeneous phenotype including chronic anovulation, hyperandrogenism and polycystic ovaries. The use of oral contraceptive pills (OCP) alters features characteristic for the syndrome. In the present study, PCOS features were compared between women using or not using OCP at the time of the study. One hundred and one women diagnosed with normogonadotrophic anovulatory infertility were included. A total of 81 (80%) women were diagnosed with PCOS (revised 2003 criteria). From these women, a total of 54 did not use OCP, whereas 27 women did. Corrected for age, women taking OCP had increased serum concentrations of sex hormone-binding globulin (P < 0.001). Serum concentrations of testosterone (P = 0.04) and androstenedione (P = 0.01) were decreased. These differences resulted in a decreased free androgen index for women currently taking OCP compared with women without (P < 0.001). The mean ovarian volume/ovary and the mean follicle number/ovary were not different. Use of OCP influences phenotype expression (the observable trait) of individual women known to suffer from PCOS by reducing hyperandrogenism. Despite taking OCP, women still fulfilled the revised 2003 criteria for the syndrome, as PCO morphology was still present. Hence, OCP use does not appreciably affect the PCOS phenotype.     

Genotypic and phenotypic characterization of Noonan syndrome: new data and review of the literature

Noonan syndrome (NS) is an autosomal dominant disorder, characterized by short stature, minor facial anomalies, and congenital heart defects. In approximately 50% of cases the condition is caused by missense mutations in the PTPN11 gene on chromosome 12, resulting in a gain of function of the protein SHP-2. In this study, PTPN11 mutation analysis was performed in 170 NS patients. In 76 (45%) of them a mutation was identified. We report on the distribution of these mutations, as well as on genotype-phenotype relationships. The benefit of the NS scoring system developed by van der Burgt et al. [(1994); Am J Med Genet 53:187-191] is shown, among physicians who consequently based their diagnosis on the NS scoring system the percentage mutation positive subjects was 54%, whereas this percentage was only 39% among physicians who made less use of the scoring system. In two patients with some uncommon manifestations mutations were found in the C-SH2 domain, a region in which defects are not often identified in NS. A trend was observed in patients carrying the 922A --> G change (Asn308Asp) receiving normal education. In one patient with NS and mild juvenile myelomonocytic leukemia (JMML) the mutation 218C --> T (Thr73Ile) was found. This confirms previous findings indicating that individuals with NS with specific mutations in PTPN11 are at risk of developing JMML.
