Neuropsychological progress during 14 years after severe traumatic brain injury in childhood and adolescence

Objective: To investigate the impact of time since injury on neuropsychological and psychosocial outcome after serious TBI in childhood or adolescence.

Methods: The subjects were eight patients with serious TBI sustained at a mean age of 14 years who had been assessed neuropsychologically at 1, 7 and 14 years after TBI. A retrospective longitudinal design was chosen to describe the development in six neuropsychological domains on the basis of the assessments. Psychosocial data were gathered from clinical knowledge and a semi-structured interview 14 years after TBI.

Results: Performance of verbal IQ shows a declining trend over the three assessments, that the performance of attention and working memory is low and that verbal learning is the cognitive domain which exhibits the largest impairments. The main psychosocial result is that three of the eight subjects went from a school situation with no adjustments to adult life with early retirement.

Conclusions: Time since insult is an important factor when assessing outcome after TBI in childhood and adolescence and that assessment of final outcome should not be done before adulthood.     

Diagnosis of brain death with technetium 99m hexamethylpropylene amine oxime

We report on the utility of technetium 99m hexamethylpropylene amine oxime (^99mTc-HMPAO) to diagnose brain death following cardiac surgery on a 49-year-old man with triple-vessel coronary artery disease. The imaging parameters and criteria to diagnose irreversible brain damage (brain death) with ^99m-TcHMPAO are outlined. Brain imaging with this tracer seems to be more reliable than classic radionuclide angiography and has a potential value to confirm the diagnosis of brain death at an early stage. In addition, it may be used to evaluate the perfusion pattern to other vital organs with potential for transplantation.Partially presented as a poster demonstration to the 19th Annual Meeting of the BNMS.

Radio-frequency tumor ablation: internally cooled electrode versus saline-enhanced technique in an aggressive rabbit tumor model

PURPOSE: To compare two methods of radio-frequency (RF) ablation, saline enhancement technique and internally cooled electrodes, for the treatment of small breast cancers in an animal model--highly aggressive VX2 rabbit tumors surrounded by adipose tissue. MATERIALS AND METHODS: Twenty-seven tumors were implanted into retroperitoneal fat of 14 New Zealand White rabbits. RF ablation was performed with ultrasonographic (US) guidance after tumors had grown to 15 mm. Fourteen tumors in seven animals were treated with internally cooled electrodes (30-mm-tip single electrode, 60 W, 10 min); 13 tumors in seven animals, with saline enhancement (0.5 mL/min of saline, 25-mm tip, 30 W, 10 min). Autopsy and histopathologic assessment were performed 3 weeks after therapy. RESULTS: Real-time US of RF ablation was not possible with either method because of obscuration by the increasing hyperechogenicity of the tumor and the surrounding adipose tissue. Equivalent efficacy was demonstrated with the two methods. Significantly greater complications were observed with the saline technique: Free retroperitoneal fluid was detected in one of seven animals with internally cooled electrodes and in all seven animals with saline enhancement (P <.01). Damage to remote structures such as the kidney, spine muscle, and skin was observed at autopsy in one of seven animals with internally cooled technique versus five of seven with saline enhancement (P <.01). CONCLUSION: Given a lower complication rate and similar treatment efficacy in an animal tumor model, internally cooled RF electrode may be advantageous to adjuvant saline infusion for the minimally invasive treatment of breast tumors.     

Cystic fibrosis at the Reunion Island (France): spectrum of mutations and genotype-phenotype for the Y122X mutation.

BACKGROUND: The Reunion Island is a French administrative department located in the Indian Ocean between the islands of Madagascar and Mauritius. Its population is known to be at a high risk of cystic fibrosis (CF). METHODS: Data concerning all CF patients born at the Reunion Island was extracted from the French CF Registry. Twenty-eight DeltaF508/DeltaF508, 17 Y122X/DeltaF508, and 11 Y122X/Y122X were included in a genotype-phenotype study. RESULTS: The detection rate of the CFTR mutations was 83% among the CF patients born at the Reunion Island. Three CFTR mutations accounted for 75% of the detected CF alleles at the Reunion Island (DeltaF508, Y122X, and 3120 + 1G-->A.). The DeltaF508/DeltaF508, DeltaF508/Y122X, and Y122X/Y122X genotypes accounted for 60.2% of the CF patients. Patients carrying at least one Y122X mutation were pancreatic insufficient, had high sweat chloride values and significantly lower anthropometric measures. The mean anthropometric values in all three groups were lower that in the whole CF population followed in "continental" France. This may reflect the poor compliance and even the refusal of treatment noted by the clinicians. CONCLUSIONS: The distribution of CFTR mutations could be explained by the history of the Reunion Island: admixture of French settlers, African and Asian populations, founder effect and isolation followed by genetic drift. The Y122X allele appears to be associated with a severe phenotype.     

Is there an association between the level of grandiose narcissism severity of psychopathology?

Background: Narcissism is a personality trait associated with both psychological health and resilience as well as with aggression and interpersonal problems. Aim: This study compares levels of total narcissism and subscale scores in inpatients, outpatients and a community sample. Methods: Inpatients (N = 186) were recruited from consecutively admitted patients to two closed units, and the outpatient group (N = 144) consisted of patients attending a psychiatric outpatient clinic. The patients and a normative community sample (N = 437) all filled in the Narcissistic Personality Inventory questionnaire (NPI-29). Results: The NPI total and subscales scores showed considerable gender differences. Among men only the Uniqueness/Entitlement subscale showed significant group differences, with inpatients showing higher mean score than the two other groups. Among women three factors, Leadership/Power, Superiority/Arrogance, and Uniqueness/ Entitlement, showed significant differences between the different levels of psychopathology. The outpatient female group regularly had the lowest group mean scores. The NPI-29 scores of the normative group showed weak internal consistencies. Conclusion: Our hypothesis of a significant association between mean levels of total narcissism and subscale scores and severity of psychopathology was not supported.     

Reduced quality of life in living kidney donors: association with fatigue, societal participation and pre-donation variables

Health related quality of life (HRQoL) of living kidney donors on average is good, but some donors experience a low HRQoL after donation. This study assessed the prevalence of reduced HRQoL and explored associations with pre‐ and post‐donation variables. 316 donors (response rate 74%) who donated a kidney between 1997 and 2009 filled in a questionnaire. HRQoL was measured using the Short‐Form 36; fatigue using the Multidimensional Fatigue Inventory; societal participation using the Utrecht Scale for Evaluation of Rehabilitation‐Participation. Donors on average had better HRQoL than the general population. However, 12% had a reduced physical (PCS) and 18% a reduced mental (MCS) HRQoL. Donors with reduced HRQoL reported greater fatigue (P < 0.01), lower societal participation (P < 0.01) and showed a trend towards statistical significance in experiencing more donor–recipient relationship changes (P = 0.07). Prior to donation, donors with reduced PCS had a higher BMI (P < 0.05) and more often smoked (P < 0.05). Donors with reduced MCS had higher expectations (P < 0.05). Reduced HRQoL is associated with higher BMI, smoking and higher expectations prior to donation. These results may be used to develop a screening instrument to select donors at high risk for reduced HRQoL.     

Association between pelvic floor muscle trauma and pelvic organ prolapse 20 years after delivery

Introduction and hypothesis

It is known that pelvic floor muscle trauma (PFMT) after vaginal delivery is associated with pelvic organ prolapse (POP) symptoms (sPOP) and signs (POP-Q ≥2) in patient populations. Our aims were to establish the prevalence and investigate a possible association between PFMT and sPOP and POP-Q ≥2 in healthy women 20 years after their first delivery.

Methods

During 2013 and 2014 we conducted a cross-sectional study among 847 women who delivered their first child between 1990 and 1997. Women responded to a postal questionnaire and were offered a clinical examination including prolapse grading and pelvic floor ultrasonography. The main outcome measures were sPOP, POP-Q ≥2 and PFMT, defined by levator avulsion or a levator hiatal area on Valsalva manoeuvre of >40 cm² on ultrasonography.

Results

Of the 847 eligible women, 608 (72 %) were examined. Data on POP symptoms, POP-Q stage, levator avulsion and levator hiatal area were available in 598, 608, 606 and 554 women, respectively, and of these 75 (13 %) had sPOP, 275 (45 %) had POP-Q ≥2, 113 (19 %) had levator avulsion and 164 (30 %) had a levator hiatal area >40 cm². Levator avulsion was associated with POP-Q ≥2 with an odds ratio (OR) of 9.91 and a 95 % confidence interval (CI) of 5.73 – 17.13, and with sPOP (OR 2.28, 95 % CI 1.34 – 3.91). Levator hiatal area >40 cm² was associated with POP-Q ≥2 (OR 6.98, 95 % CI 4.54, – 10.74) and sPOP (OR 3.28, 95 % CI 1.96 – 5.50).

Conclusion

Many healthy women selected from the general population have symptoms and signs of POP 20 years after their first delivery, and PFMT is associated with POP-Q ≥2 and sPOP.

     

Functional and cognitive rehabilitation interventions during intensive care admission: A protocol for a systematic integrative review

Background

Long-term cognitive impairment occurs in up to 60% of intensive care unit (ICU) survivors. Early use of functional and cognitive rehabilitation interventions, while patients are still in ICU, may reduce cognitive decline. We aim to describe the functional and cognitive interventions used during the ICU stay, the healthcare professionals providing interventions, and the potential impact on functional and cognitive rehabilitation.

Method

In this integrative systematic review, we will include empirical qualitative, quantitative, mixed- and multiple-methods studies assessing the use of functional and cognitive rehabilitation provided in ICU. We will identify studies in relevant electronic databases from 2012 to 2022, which will be screened for eligibility by at least two reviewers. Literature reported as narrative reviews and editorials will be excluded. We will assess the impact of interventions evaluating a cognitive and functional function, quality of life, and all-cause mortality at 6–12 months after ICU discharge. The Revised Cochrane risk-of-bias Tool will be used for assessing risk of bias in clinical trials. For observational studies, we will use the National Institutes of Health Quality Assessment tool for Observational Cohort and Cross-Sectional Studies. Furthermore, we will use the critical appraisal skills programme for qualitative studies and the mixed methods appraisal tool for mixed methods studies. We will construct four matrices, including results describing which ICU patients and healthcare professionals were engaged in rehabilitation, which interventions were included in early rehabilitation in ICU, the potential impact on patient outcomes of rehabilitation interventions provided in ICU and a narrative synthesis of themes. A summary of the main results will be reported using modified GRADE methodology.

Impact

This integrative review will inform the feasibility randomised clinical trial testing the development of a complex intervention targeting functional and cognitive rehabilitation for patients in ICU.     

Incidence of and risk factors for acute stress disorder in children with injuries

BACKGROUND: To assess the incidence of and risk factors for Acute Stress Disorder (ASD) in children with injuries. Numerous studies have documented the increased incidence of PTSD in those initially diagnosed with ASD. PTSD symptoms cause tremendous morbidity and may persist for many years in some children. METHODS: Children hospitalized with one or more injuries were interviewed and assessed with the following: Child Stress Disorders Checklist (CSDC), Family Strains Scale, Brief Symptom Inventory (BSI) and Facial Pain Scale. RESULTS: Participants included sixty-five children (ages 7-18 years). The mechanisms of injury varied (e.g. MVC, penetrating). The mean injury severity score was 8.9 +/- 7. The mean length of hospital stay was 4.6 +/- 4.6 days. Altogether, 18 (27.7%) of participants met DSM IV criteria for ASD during their acute hospital stay. Risk factors such as level of family stress, caregiver stress, child's experience of pain, and child's age were predictive of acute stress symptoms. CONCLUSION: We have identified four risk factors of ASD that have implications for the treatment, and possibly, preventative intervention for PTSD. Further investigation and greater understanding of risk factors for ASD in children with injuries may facilitate the design of acute interventions to prevent the long-term negative outcomes of traumatic events.
