RESUMEN

PURPOSE: Adolescence is a sensitive period for developing mental health problems. Interventions targeting emotion regulation have shown promising transdiagnostic effects for this group, but optimization efforts are called for. In the current study, we used an element-based approach to identify potentially active ingredients in interventions measuring emotion regulation, to guide further optimization. METHODS: We coded practice elements in 30 studies based on a systematic review of mental health interventions measuring emotion regulation in adolescents (N = 2,389 participants, mean age 13-17 years). Using a three-level modeling approach, we then investigated the difference in effect on emotion regulation between studies of interventions with and without these practice elements. RESULTS: We identified 75 practice elements and 15 element categories used in the included interventions. Results showed significantly stronger effects on emotion regulation when interventions included the practice elements Setting goals for treatment (difference in d = 0.40, 95% CI [0.09, 0.70], p = .012) and Psychoeducation about acceptance (difference in d = 0.58, 95% CI [0.09, 1.07], p = .021). Furthermore, a total of 11 elements and four overall categories were identified as potentially active ingredients, based on an effect size difference of > 0.20 between interventions with and without the elements. CONCLUSION: The results can direct experimental research into the selection of practices that are most likely key to mechanisms of change in interventions addressing emotion regulation for adolescents. The challenge of measuring emotion regulation is discussed.

RESUMEN

BACKGROUND: The conceptualization of post-traumatic stress disorder (PTSD) in the upcoming International Classification of Diseases (ICD)-11 differs in many respects from the diagnostic criteria in the Diagnostic and Statistical Manual for Mental Disorders, fifth edition (DSM-5). The consequences of these differences for individuals and for estimation of prevalence rates are largely unknown. This study investigated the concordance of the two diagnostic systems in two separate samples at two separate waves. METHOD: Young survivors of the 2011 Norway attacks (n = 325) and their parents (n = 451) were interviewed at 4-6 months (wave 1) and 15-18 months (wave 2) after the shooting. PTSD was assessed with the UCLA PTSD Reaction Index for DSM-IV adapted for DSM-5, and a subset was used as diagnostic criteria for ICD-11. RESULTS: In survivors, PTSD prevalence did not differ significantly at any time point, but in parents, the DSM-5 algorithm produced significantly higher prevalence rates than the ICD-11 criteria. The overlap was fair for survivors, but amongst parents a large proportion of individuals met the criteria for only one of the diagnostic systems. No systematic differences were found between ICD-11 and DSM-5 in predictive validity. CONCLUSIONS: The proposed ICD-11 criteria and the DSM-5 criteria performed equally well when identifying individuals in distress. Nevertheless, the overlap between those meeting the PTSD diagnosis for both ICD-11 and DSM-5 was disturbingly low, with the ICD-11 criteria identifying fewer people than the DSM-5. This represents a major challenge in identifying individuals suffering from PTSD worldwide, possibly resulting in overtreatment or unmet needs for trauma-specific treatment, depending on the area of the world in which patients are being diagnosed.

RESUMEN

AIM: To examine whether diabetes-specific emotional distress was related to follow-up glycaemic control in adults with Type 1 diabetes mellitus. METHODS: Adults with Type 1 diabetes mellitus completed the Diabetes Distress Scale and reported sociodemographic information when attending a clinical consultation at a university endocrinology unit. Blood samples to determine baseline HbA1c were taken during consultations. All respondents' HbA1c measurements registered from January 2009 to December 2011 were collected from medical records. The relationship between baseline diabetes-specific emotional distress and HbA1c was examined with linear mixed-effects models in 175 patients with complete data. RESULTS: After controlling for confounders, baseline diabetes-specific emotional distress and glycaemic control were significantly associated (fixed-effect coefficient 0.40, P < 0.001) and the regimen-related distress subscale had the strongest association with glycaemic control (fixed-effect coefficient 0.47, P < 0.001). The two-item measure of diabetes-specific distress had a weaker but still significant association with glycaemic control (fixed-effect coefficient 0.31, P < 0.001). None of these relationships was significant after adjusting for the baseline HbA1c . CONCLUSIONS: People with elevated baseline diabetes-specific emotional distress are at risk of prolonged suboptimum glycaemic control; therefore, elevated diabetes-specific emotional distress, especially regimen-related distress, might be an important marker for prolonged suboptimum glycaemic control, and might indicate a need for special attention regarding patient self-management.

RESUMEN

AIMS: Electronic health (eHealth) sources have great potential to improve patients' access to health information for self-management of secondary prevention after percutaneous coronary intervention (PCI). It remains unclear, however, whether patients are health-related digitally active and whether they have sufficient eHealth literacy. This study aimed to determine the extent to which patients after PCI are health-related digitally active at baseline, 2 and 6 months after PCI, and to determine the association between patients' eHealth literacy and their health-related digital activity. METHODS AND RESULTS: This multicentre cohort study included patients at three large referral PCI centres in Norway (n = 1970). Data were collected from medical records, national registries, and patients' self-reports. The eHealth Literacy Scale (eHEALS) assessed patients' eHealth literacy. At baseline, 67% had used the internet to find health information. The mean eHEALS score was 25.71 (standard deviation 6.22), illustrating a lower level of eHealth literacy. There were substantial associations between eHealth literacy and use of the internet to find health information [coefficient 10.90, 95% confidence interval (CI) 8.05-14.57]. At the 2-month follow-up, there were substantial associations between baseline eHealth literacy and use of the internet to find information about health, prevention, illness, or treatment [odds ratio (OR) 1.19, 95% CI 1.14-1.24] and use of health applications (OR 1.15, 95% CI 1.08-1.22). CONCLUSION: This study provides evidence that patients' level of eHealth literacy after PCI is associated to how patients use, and can make use of, eHealth technology for health information. REGISTRATION: ClinicalTrials.gov (NCT03810612).

RESUMEN

BACKGROUND: Socioeconomic status (SES) and social support influences cancer survival. If SES and social support affects cancer treatment has not been thoroughly explored. METHODS: A cohort consisting of all patients who were initially diagnosed with or who developed metastatic colorectal cancer (mCRC, n=781) in three Scandinavian university hospitals from October 2003 to August 2006 was set up. Clinical and socioeconomic data were registered prospectively. RESULTS: Patients living alone more often had synchronous metastases at presentation and were less often treated with combination chemotherapy than those cohabitating (HR 0.19, 95% CI 0.04-0.85, P=0.03). Surgical removal of metastases was less common in patients living alone (HR 0.29, 95% CI 0.10-0.86, P=0.02) but more common among university-educated patients (HR 2.22, 95% CI 1.10-4.49, P=0.02). Smoking, being married and having children did not influence treatment or survival. Median survival was 7.7 months in patients living alone and 11.7 months in patients living with someone (P<0.001). Living alone remained a prognostic factor for survival after correction for age and comorbidity. CONCLUSION: Patients living alone received less combination chemotherapy and less secondary surgery. Living alone is a strong independent risk factor for poor survival in mCRC.

RESUMEN

BACKGROUND: The objective of this study was to assess markers of spermatogenesis in long-term survivors of testicular cancer (TC) according to treatment, and to explore correlations between the markers and associations with achieved paternity following TC treatment. METHODS: In 1191 TC survivors diagnosed between 1980 and 1994, serum-follicle stimulating hormone (s-FSH; n=1191), s-inhibin B (n=441), and sperm counts (millions per ml; n=342) were analysed in a national follow-up study in 1998-2002. Paternity was assessed by a questionnaire. RESULTS: At median 11 years follow-up, 44% had oligo- (<15 millions per ml; 29%) or azoospermia (15%). Sperm counts and s-inhibin B were significantly lower and s-FSH was higher after chemotherapy, but not after radiotherapy (RT), when compared with surgery only. All measures were significantly more abnormal following high doses of chemotherapy (cisplatin (Cis)>850 mg, absolute cumulative dose) compared with lower doses (Cis ≤ 850 mg). Sperm counts were moderately correlated with s-FSH (-0.500), s-inhibin B (0.455), and s-inhibin B : FSH ratio (-0.524; all P<0.001). All markers differed significantly between those who had achieved post-treatment fatherhood and those with unsuccessful attempts. CONCLUSION: The RT had no long-term effects on the assessed markers of spermatogenesis, whereas chemotherapy had. At present, the routine evaluation of s-inhibin B adds little in the initial fertility evaluation of TC survivors.

RESUMEN

BACKGROUND: Platinum-based doublet chemotherapy is the standard first-line treatment for advanced non-small cell lung cancer (NSCLC), but earlier studies have suggested that non-platinum combinations are equally effective and better tolerated. We conducted a national, randomised study to compare a non-platinum with a platinum combination. METHODS: Eligible patients had stage IIIB/IV NSCLC and performance status (PS) 0-2. Patients received up to three cycles of vinorelbine 60 mg m(-2) p.o.+gemcitabine 1000 mg m(-2) i.v. day 1 and 8 (VG) or vinorelbine 60 mg m(-2) p.o. day 1 and 8+carboplatin area under the curve=5 (Calvert's formula) i.v. day 1 (VC). Patients ≥75 years received 75% of the dose. Endpoints were overall survival, health-related quality of life (HRQoL), toxicity, and the use of radiotherapy. RESULTS: We randomised 444 patients from September 2007 to April 2009. The median age was 65 years, 58% were men and 25% had PS 2. Median survival was VG: 6.3 months; VC: 7.0 months, P=0.802. Vinorelbine plus carboplatin patients had more grade III/IV nausea/vomiting (VG: 4%, VC: 12%, P=0.008) and grade IV neutropenia (VG: 7%, VC: 19%, P<0.001). Infections, HRQoL and the use of radiotherapy did not differ significantly between the treatment groups. CONCLUSION: The two regimens yielded similar overall survival. The VG combination had only a slightly better toxicity profile.

RESUMEN

BACKGROUND: Cognitive impairments are common after critical illness. Aetiology and effects of cognitive impairments in this setting are not fully revealed. The aim of this study was to investigate the effect of critical illness and intensive care unit (ICU) treatment on cerebral function. METHODS: Adult ICU patients with no previous history of cerebral disorders were included. Non-delirious patients scoring ≥ 24 on mini-mental state examination on ICU discharge were explored neuropsychologically using the Cambridge Neuropsychological Test Automated Battery (CANTAB) to classify cognitive impairments. Tests were repeated at 3 and 12 months. Results were compared with a normal reference population and a surgical comparison group. RESULTS: We included 55 patients. Eighteen of 28 patients were cognitively impaired, and it was not possible to classify 27 patients. The ICU survivors tested with CANTAB scored significantly lower than the reference population. They also scored worse than a surgical comparison group but significantly on only one of 10 measures. At 3 months follow-up, included patients scored significantly worse on one of 10 reported CANTAB measures. There were no differences at 12 months. We found no associations between age, co-morbidity, Simplified Acute Physiology Score II, Sequential Organ Failure Assessment score, presence of cardiovascular disease, duration of ventilatory support and length of ICU stay, and cognitive impairments. Having a cognitive impairment did not affect other outcome measures such as mortality, health-related quality of life, and institutionalization. CONCLUSIONS: Cognitive impairments are common after critical illness and may be caused by the critical illness in itself. Incidences are high after ICU discharge (64%) but drops rapidly during the first 3 months after discharge.

RESUMEN

Our study describes the new seventh edition of the TNM system for lung cancer in a national population and its clinical implications. We classified 1,885 operated patients with lung cancer, reported to the Cancer Registry of Norway (Oslo, Norway) from 2001 to 2005, according to the sixth and the seventh edition of the TNM system. We compared survival differences adjusting for known prognostic factors. Furthermore, we evaluated the overall predictive ability of both editions using Harrell's concordance index. Survival curves by stage for each of the editions were similar; however, a better description of stage IIIB was observed in the seventh edition. Survival rates of T1b and T2a tumours were similar (log rank p = 0.94). The concordance index was 0.68 for both editions, indicating no overall difference in their predictive accuracy. In the seventh edition, 211 (29%) stage IB patients migrated to stage II and 161 (48%) patients migrated from stage IIB to IIA. Stage migrations could change the treatment for up to 326 (17.3%) of the study patients. The seventh edition did not improve the overall predictive ability of the TNM system; however, the new classification implies changes in treatment for nearly one-fifth of the cases. The implications of the seventh TNM edition for the outcomes of patients should be studied further.

RESUMEN

AIMS: To analyse, in a population-based study, the association between parental fear of hypoglycaemia and (i) the prevalence of hypoglycaemia and diabetes treatment factors in children with Type 1 diabetes and (ii) emotional distress in mothers and fathers. METHODS: Mothers (n = 103) and fathers (n = 97) of 115 children with Type 1 diabetes (1-15 years old) participated in the study. In addition to demographic and disease-specific data, the participants completed the Hypoglycaemia Fear Survey-Parent version (HFS-P) (worry and behaviour subscales) and the Hopkins Symptom Checklist-25 items (HSCL-25) to measure emotional distress. RESULTS: A higher HFS-P worry score was associated with higher glycated haemoglobin (HbA(1c)), a higher frequency (>or= 7) of what parents experienced as problematic hypoglycaemic events during the past year and co-morbid disease in the child. A higher HFS-P behaviour score was associated with children receiving insulin injections compared with using an insulin pump and a higher frequency (>or= 7 per day) of blood glucose measurements. The mothers had higher scores than the fathers in both the worry and behaviour subscales. The mothers' and the fathers' HFS-P worry scores correlated significantly with their HSCL-25 scores. CONCLUSIONS: The association between a higher level of hypoglycaemic-related fear and parental emotional distress and poorer glycaemic control in the child emphasizes the need for programmes to support and guide parents. The results suggest that future interventions should target both the parents' fear and appropriate ways to prevent hypoglycaemia in children with Type 1 diabetes.

RESUMEN

INTRODUCTION: Frequent blood donations may lead to a negative iron balance. Iron depletion may be prevented by iron supplementation after whole blood donations. The aim of this study was to compare the short time changes in iron status after donation in two groups randomized to iron supplementation or no additional iron. A second objective was to evaluate the effect of iron supplementation in donors having HFE-variants compared to HFE wild types. METHODS: Subjects of both genders (199 women, 200 men) were randomised to receive iron supplementation or no additional iron after donation. Iron status, defined by the concentration of haemoglobin, serum ferritin, soluble transferrin receptor, concentration of haemoglobin in reticulocytes (CHr) and percent hypochrome mature red blood cells, was determined at the start of donation and 8 +/- 2 days after donation. HFE genotyping was performed at reappearance. RESULTS: There was a significant difference between the two study groups on all the iron status parameters. CHr was an efficient, early marker of ongoing synthesis of haemoglobin. Heterozygosity for the HFE variants C282Y and H63D had no statistically significant influence on the iron status. The donor's baseline serum ferritin value may be basis for an individual iron supplementation regimen, as donors with serum ferritin >50 microg/l do not seem to utilize the iron supplementation, but prefer endogenous iron to restore the loss of haemoglobin. CONCLUSION: Iron supplementation had a significant positive impact on the restoration of iron status one week after donation.

RESUMEN

BACKGROUND: Evidence-based treatment protocols including therapeutic hypothermia have increased hospital survival to over 50% in unconscious out-of-hospital cardiac arrest survivors. In this study we estimated the incidence of cognitive dysfunctions in a group of cardiac arrest survivors with a high functional outcome treated with therapeutic hypothermia. Secondarily, we assessed the cardiac arrest group's level of cognitive performance in each tested cognitive domain and investigated the relationship between cognitive function and age, time since cardiac arrest and health-related quality of life (HRQOL). METHODS: We included 26 patients 13-28 months after a cardiac arrest. All patients were scored using the Cerebral Performance Category scale (CPC) and Mini-Mental State Examination (MMSE). Twenty-five of the patients were tested for cognitive function using the Cambridge Neuropsychological Test Automated Battery (CANTAB). These patients were tested using four cognitive tests: Motor Screening Test, Delayed Matching to Sample, Stockings of Cambridge and Paired Associate Learning from CANTAB. All patients filled in the Short Form-36 for the assessment of HRQOL. RESULTS: Thirteen of 25 (52%) patients were classified as having a cognitive dysfunction. Compared with the reference population, there was no difference in the performance in motor function and delayed memory but there were significant differences in executive function and episodic memory. We found no associations between cognitive function and age, time since cardiac arrest or HRQOL. CONCLUSION: Half of the patients had a cognitive dysfunction with reduced performance on executive function and episodic memory, indicating frontal and temporal lobe affection, respectively. Reduced performance did not affect HRQOL.

RESUMEN

OBJECTIVES: In this volumetric study of the vestibular schwannoma, we evaluated the accuracy and reliability of several approximation methods that are in use, and determined the minimum volume difference that needs to be measured for it to be attributable to an actual difference rather than a retest error. We also found empirical proportionality coefficients for the different methods. DESIGN/SETTING AND PARTICIPANTS: Methodological study with investigation of three different VS measurement methods compared to a reference method that was based on serial slice volume estimates. These volume estimates were based on: (i) one single diameter, (ii) three orthogonal diameters or (iii) the maximal slice area. Altogether 252 T1-weighted MRI images with gadolinium contrast, from 139 VS patients, were examined. MAIN OUTCOME MEASURES: The retest errors, in terms of relative percentages, were determined by undertaking repeated measurements on 63 scans for each method. Intraclass correlation coefficients were used to assess the agreement between each of the approximation methods and the reference method. The tendency for approximation methods to systematically overestimate/underestimate different-sized tumours was also assessed, with the help of Bland-Altman plots. RESULTS: The most commonly used approximation method, the maximum diameter, was the least reliable measurement method and has inherent weaknesses that need to be considered. This includes greater retest errors than area-based measurements (25% and 15%, respectively), and that it was the only approximation method that could not easily be converted into volumetric units. Area-based measurements can furthermore be more reliable for smaller volume differences than diameter-based measurements. CONCLUSIONS: All our findings suggest that the maximum diameter should not be used as an approximation method. We propose the use of measurement modalities that take into account growth in multiple dimensions instead.

RESUMEN

BACKGROUND AND OBJECTIVES: The impact of a poor iron status on the difficulties to keep recruitment of new donors at pace with the ongoing increased demand for blood transfusions was studied by comparing the iron status of new donors recruited in 1993-1997 and in 2005-2006. MATERIALS AND METHODS: Iron status was defined by haemoglobin and serum ferritin. Inclusion criteria for approving new donors were haemoglobin >/= 12.5 g/dl for women and >/= 13.5 g/dl for men, and serum ferritin > 15 microg/l for both genders. Data were gathered retrospectively from 943 subjects (55% women) in the 1990 ties and prospectively from 1013 subjects (63% women) 10 years later. RESULTS: In women, there was a significant fall in haemoglobin and serum ferritin mean values from 13.2 to 13.1 g/dl and from 30.9 to 26.9 microg/l, respectively. Rejection due to low haemoglobin was significantly increased from 14% to 24%. In men, there were minor changes that did not affect rejection rates. CONCLUSION: Iron status of women who want to serve as blood donors has deteriorated in the last 10 years, leading to an increased rejection due to haemoglobin below the inclusion criterion for blood donors.

RESUMEN

Cognitive functioning was compared in 29 children diagnosed with fetal alcohol syndrome (FAS), 35 children with fetal alcohol effects (FAE), and 66 psychotropic drugs-exposed (PDE) children using Wechsler tests and the neuropsychological test battery NEPSY. In the FAS group, verbal IQ (VIQ=78), performance IQ (PIQ=77), and full scale IQ (FSIQ=75) were significantly lower as compared to the FAE and PDE groups. In the PDE group VIQ and FSIQ were significantly higher than in the FAE group. In the FAS group, processing speed (PS) was significantly lower than the other three factors. In the FAE group, perceptual organization (PO) was significantly higher, whereas PS was significantly lower than the other factors. In the PDE group, verbal comprehension (VC) was significantly higher than the other factors. Attention subscales on the NEPSY were significantly lower in all the three groups. Prenatal alcohol exposure affects IQ levels more than exposure to psychotropic drugs. Attentional problems were found in all children when tested with the NEPSY in all groups.

RESUMEN

INTRODUCTION: The effects of blood donation on iron status in donors without iron supplementation were studied. Analysing interactions between donations and iron status markers may predict these effects. MATERIALS AND METHODS: Haemoglobin (Hb) and serum ferritin were analysed in 893 donors over 1 year. Serum transferrin receptor (sTfR) was measured at the first and last donation. RESULTS: Prolonged intervals prevented decrease in Hb in women and in ferritin for both genders. In women, a high TfR-F index (sTfR/log ferritin) predicted fall in Hb. CONCLUSION: Adjusting the donation intervals is a way to prevent iron deficiency in blood donors.

RESUMEN

BACKGROUND: To investigate whether the introduction of modern third-generation chemotherapy was associated with survival benefits in a national population of patients with advanced non-small cell lung cancer (ANSCLC) and to explore geographical and temporary variations in the utilisation of chemotherapy. METHODS: All patients with ANSCLC in the Cancer Registry of Norway during 1994-2005 were included. Using sales of vinorelbine as an indicator for chemotherapy, annual county utilisation rates were calculated. Survival before and after the general introduction of vinorelbine and associations between survival and variations in utilisation in counties were investigated. In a subgroup, the predictors of having received chemotherapy were explored. RESULTS: Of 24 875 registered patients with lung cancer, 13 757 had ANSCLC. The annual utilisation of the indicator drug in Norway increased from 3.7 to 184.2 g (1998-2005). Median survival increased from 149 to176 days (p<0.001). The adjusted hazard ratio (HR) for a diagnosis after the introduction was 0.93 (95% CI 0.88 to 0.99). County utilisation rates of vinorelbine (increments of 100 mg/1000 inhabitants) were inversely associated with the risk of death (HR 0.84, 95% CI 0.73 to 0.98). County of residence predicted chemotherapy utilisation with odds ratios in the range 0.13 (95% CI 0.1 to 0.19) to 1.04 (95% CI 0.64 to 1.69), a county with traditionally high utilisation as reference. CONCLUSION: Utilisation of third-generation chemotherapy was associated with slightly increased survival of patients with ANSCLC. Geographical and temporal differences in utilisation indicate variable quality of delivered care.

RESUMEN

OBJECTIVE: To examine the occurrence and clinical and demographic correlates of REM sleep behaviour disorder (RBD) in patients with Parkinson's disease (PD) in a community-based cohort over 8 years. METHODS: 231 patients with PD were included in a population-based prevalence study in 1993. Patients were then followed prospectively and reexamined after 4 and 8 years. Semi-structured interviews for information on clinical and demographic data were applied at all study visits. Standardised rating scales of parkinsonism, depression and cognitive impairment were used. The diagnosis of probable RBD (pRBD) was based on a sleep questionnaire. Proportional-odds ordinal logistic regression models for clustered data were used to study the relationship between pRBD and various demographic and clinical variables. RESULTS: 231 patients were evaluated for RBD in 1993 and, after 4 and 8 years, 142 and 89 patients, respectively, were available for re-evaluation. The frequency of pRBD varied from 14.6% to 27% during the study period. Probable RBD was related to male gender, higher dopaminergic treatment and less severe parkinsonism. CONCLUSION: We found that the frequency of pRBD varied over time and that it is associated with male gender, less parkinsonism and higher levodopa equivalent dose. Our findings indicate that dopaminergic therapy may contribute to the expression of RBD and that RBD is symptomatic in earlier stages of PD.

RESUMEN

BACKGROUND: The aim of the present study was to assess potential long-term reduction in health-related quality of life (HRQOL) in adult trauma patients 2-7 years after discharge from an intensive care unit (ICU), and to study possible determinants of the HRQOL reduction. METHODS: Follow-up study of a cohort of 341 trauma patients admitted to the ICU of a university hospital during 1998-2003. Of the 228 eligible patients, 210 (92%) completed the study. A telephone interview using the EuroQol 5-D (EQ-5D) was conducted. Patients reported their HRQOL both at present and before trauma. RESULTS: Before trauma 88% reported in retrospect no problem in any EQ-5D dimension, compared with 20% at follow-up. After trauma (median 4.0 years) 58% suffered pain/discomfort, 44% reported alterations in usual activities, 40% reduced mobility, 35% anxiety/depression, and 15% limited autonomy. A total of 74% experienced reduction in HRQOL. Severe problems were reported by 16%. Women experienced more anxiety/depression than men. Simplified Acute Physiology Score (SAPS) II and Injury Severity Score (ISS) were significantly associated with impaired HRQOL, while age was not. Patients with severe head injury reported better HRQOL than those without severe head injury. CONCLUSION: More than 2 years post-injury, 74% reported impaired HRQOL but only 16% had severe problems. The majority still suffered pain/discomfort, indicating that pain management is a key factor in improving long-term outcome after severe trauma.
