Clinical and Cost Effectiveness of Online Cognitive Behavioral Therapy in Children With Functional Abdominal Pain Disorders
- 2019
-
In: Clinical Gastroenterology and Hepatology. - : Elsevier BV. - 1542-3565 .- 1542-7714. ; 17:11

Journal article (peer-reviewed)abstract
- BACKGROUND & AIMS: Scalable and effective treatments are needed for children with functional abdominal pain disorders (FAPDs). We performed a randomized controlled trial of the efficacy and cost effectiveness of cognitive behavioral therapy delivered online (Internet-CBT) compared with usual therapy. METHODS: We studied children (age, 8-12 y) diagnosed with FAPDs, based on the Rome IV criteria, in Sweden from September 2016 through April 2017. The patients were assigned randomly to groups that received 10 weeks of therapist-guided, internet-delivered cognitive behavioral therapy (Internet-CBT, n = 46) or treatment as usual (treatments within the health care and school systems, including medications and visits to doctors and other health care professionals; n = 44). The primary outcome was global child-rated gastrointestinal symptom severity assessed using the Pediatric Quality of Life Gastrointestinal Symptom scale. All outcomes were collected from September 2016 through January 2018. Secondary outcomes included quality of life, gastrointestinal-specific anxiety, avoidance behaviors, and parental responses to children's symptoms. Societal costs and costs for health care consumption were collected during the treatment. RESULTS: Children who received Internet-CBT had a significantly larger improvement in gastrointestinal symptom severity with a medium effect size (Cohen's d = 0.46; 95% CI, 0.05-0.88; number needed to treat, 3.8) compared with children who received the treatment as usual. The children's quality of life, gastrointestinal-specific anxiety, avoidance behaviors, and parental responses to children's symptoms also improved significantly in the Internet-CBT group compared with the treatment as usual group. The effects of Internet-CBT persisted through 36 weeks of follow-up evaluation. Children who received Internet-CBT had significantly less health care use than children who received treatment as usual, with an average cost difference of US $137 (P = .011). We calculated a cost savings of US $1050 for every child treated with Internet-CBT compared with treatment as usual. CONCLUSIONS: In a randomized trial of pediatric patients with FAPDs, we found Internet-CBT to be clinically cost effective compared with treatment as usual. Internet-CBThas the potential to increase the availability of treatment for a number of patients and reduce health care costs.

Molecular and cytogenetic analysis in stillbirth: results from 481 consecutive cases
- 2014
-
In: Fetal diagnosis and therapy. - : S. Karger AG. - 1421-9964 .- 1015-3837. ; 36:4, s. 326-332

Journal article (peer-reviewed)abstract
- <b><i>Introduction:</i></b> The underlying causes of stillbirth are heterogeneous and in many cases unexplained. Our aim was to conclude clinical results from karyotype and quantitative fluorescence-polymerase chain reaction (QF-PCR) analysis of all stillbirths occurring in Stockholm County between 2008 and 2012. By screening a subset of cases, we aimed to study the possible benefits of chromosomal microarray (CMA) in the analysis of the etiology of stillbirth. <b><i>Methods:</i></b> During 2008-2012, 481 stillbirths in Stockholm County were investigated according to a clinical protocol including karyotype or QF-PCR analysis. CMA screening was performed on a subset of 90 cases, corresponding to all stillbirths from 2010 without a genetic diagnosis. <b><i>Results:</i></b> Chromosomal aberrations were detected by karyotype or QF-PCR analysis in 7.5% of the stillbirths. CMA analysis additionally identified two known syndromes, one aberration disrupting a known disease gene, and 26 variants of unknown significance. Furthermore, CMA had a significantly higher success rate than karyotyping (100 vs. 80%, p < 0.001). <b><i>Discussion:</i></b> In the analysis of stillbirth, conventional karyotyping is prone to failure, and QF-PCR is a useful complement. We show that CMA has a higher success rate and aberration detection frequency than these methods, and conclude that CMA is a valuable tool for identification of chromosomal aberrations in stillbirth.

Placental IGF-I, estrogen receptor, and progesterone receptor expression, and maternal anthropometry in growth-restricted pregnancies in the Swedish population
- 2011
-
In: Hormone research in paediatrics. - : S. Karger AG. - 1663-2826 .- 1663-2818. ; 75:2, s. 131-137
-
Journal article (peer-reviewed)abstract
- <i>Background/Aims:</i> Fetal growth restriction is a complex problem of pregnancy arising from multiple etiologies. Key regulatory elements of growth are the insulin-like growth factor (IGF) axis, and estrogen and progesterone receptors. The aims were to determine the relations of expression of IGF-I, estrogen receptors α and β (ERα and ERβ, respectively), and progesterone receptor (PR), with maternal anthropometry, focusing on birth weight outcomes. <i>Methods:</i> Placental samples were obtained from 33 patients following delivery. mRNA expression was determined by a solution hybridization technique. Samples were divided into normal control (NC) and growth-restricted (GR) groups. <i>Results:</i> IGF-I expression was lower in the GR as compared to the NC group. PR levels correlated positively with IGF-I expression, infant anthropometry, and gestational age (GR). ERα correlated positively with PR expression (NC), and maternal BMI at delivery (GR). ERβ correlated positively with maternal delivery weight and gestational age (NC). <i>Conclusion:</i> The differences in placental expression of IGF-I emphasize its key role in birth weight outcomes. We further suggest the importance of PR expression in the pathogenesis of intrauterine growth restriction, as there were direct correlations of PR expression with both IGF-I expression and infant anthropometric parameters, as well as gestational age.

Restoring proper radical generation by azide binding to the iron site of the E238A mutant R2 protein of ribonucleotide reductase from Escherichia coli.
- 2001
-
In: Journal of Biological Chemistry. - 0021-9258 .- 1083-351X. ; 276:29, s. 26852-26859
-
Journal article (peer-reviewed)abstract
- The enzyme activity of Escherichia coli ribonucleotide reductase requires the presence of a stable tyrosyl free radical and diiron center in its smaller R2 component. The iron/radical site is formed in a reconstitution reaction between ferrous iron and molecular oxygen in the protein. The reaction is known to proceed via a paramagnetic intermediate X, formally a Fe(III)-Fe(IV) state. We have used 9.6 GHz and 285 GHz EPR to investigate intermediates in the reconstitution reaction in the iron ligand mutant R2 E238A with or without azide, formate, or acetate present. Paramagnetic intermediates, i.e. a long-living X-like intermediate and a transient tyrosyl radical, were observed only with azide and under none of the other conditions. A crystal structure of the mutant protein R2 E238A/Y122F with a diferrous iron site complexed with azide was determined. Azide was found to be a bridging ligand and the absent Glu-238 ligand was compensated for by azide and an extra coordination from Glu-204. A general scheme for the reconstitution reaction is presented based on EPR and structure results. This indicates that tyrosyl radical generation requires a specific ligand coordination with 4-coordinate Fe1 and 6-coordinate Fe2 after oxygen binding to the diferrous site.

Monoclonal antibodies selective for α-synuclein oligomers/protofibrils recognize brain pathology in Lewy body disorders and α-synuclein transgenic mice with the disease-causing A30P mutation
- 2013
-
In: Journal of Neurochemistry. - : Wiley-Blackwell. - 0022-3042 .- 1471-4159. ; 126:1, s. 131-144

Journal article (peer-reviewed)abstract
- Inclusions of intraneuronal alpha-synuclein (-synuclein) can be detected in brains of patients with Parkinson's disease and dementia with Lewy bodies. The aggregation of -synuclein is a central feature of the disease pathogenesis. Among the different -synuclein species, large oligomers/protofibrils have particular neurotoxic properties and should therefore be suitable as both therapeutic and diagnostic targets. Two monoclonal antibodies, mAb38F and mAb38E2, with high affinity and strong selectivity for large -synuclein oligomers were generated. These antibodies, which do not bind amyloid-beta or tau, recognize Lewy body pathology in brains from patients with Parkinson's disease and dementia with Lewy bodies and detect pathology earlier in -synuclein transgenic mice than linear epitope antibodies. An oligomer-selective sandwich ELISA, based on mAb38F, was set up to analyze brain extracts of the transgenic mice. The overall levels of -synuclein oligomers/protofibrils were found to increase with age in these mice, although the levels displayed a large interindividual variation. Upon subcellular fractionation, higher levels of -synuclein oligomers/protofibrils could be detected in the endoplasmic reticulum around the age when behavioral disturbances develop. In summary, our novel oligomer-selective -synuclein antibodies recognize relevant pathology and should be important tools to further explore the pathogenic mechanisms in Lewy body disorders. Moreover, they could be potential candidates both for immunotherapy and as reagents in an assay to assess a potential disease biomarker.

Dietary inorganic nitrate improves mitochondrial efficiency in humans.
- 2011
-
In: Cell Metabolism. - : Elsevier BV. - 1550-4131 .- 1932-7420. ; 13:2, s. 149-159
-
Journal article (peer-reviewed)abstract
- Nitrate, an inorganic anion abundant in vegetables, is converted in vivo to bioactive nitrogen oxides including NO. We recently demonstrated that dietary nitrate reduces oxygen cost during physical exercise, but the mechanism remains unknown. In a double-blind crossover trial we studied the effects of a dietary intervention with inorganic nitrate on basal mitochondrial function and whole-body oxygen consumption in healthy volunteers. Skeletal muscle mitochondria harvested after nitrate supplementation displayed an improvement in oxidative phosphorylation efficiency (P/O ratio) and a decrease in state 4 respiration with and without atractyloside and respiration without adenylates. The improved mitochondrial P/O ratio correlated to the reduction in oxygen cost during exercise. Mechanistically, nitrate reduced the expression of ATP/ADP translocase, a protein involved in proton conductance. We conclude that dietary nitrate has profound effects on basal mitochondrial function. These findings may have implications for exercise physiology- and lifestyle-related disorders that involve dysfunctional mitochondria.

Mitochondrial oxygen affinity predicts basal metabolic rate in humans
- 2011
-
In: The FASEB Journal. - : Wiley. - 0892-6638 .- 1530-6860. ; 25:8, s. 2843-52

Journal article (peer-reviewed)abstract
- The basal metabolic rate (BMR) is referred to as the minimal rate of metabolism required to support basic body functions. It is well known that individual BMR varies greatly, even when correcting for body weight, fat content, and thyroid hormone levels, but the mechanistic determinants of this phenomenon remain unknown. Here, we show in humans that mass-related BMR correlates strongly to the mitochondrial oxygen affinity (p50(mito); R(2)=0.66, P=0.0004) measured in isolated skeletal muscle mitochondria. A similar relationship was found for oxygen affinity and efficiency during constant-load submaximal exercise (R(2)=0.46, P=0.007). In contrast, BMR did not correlate to overall mitochondrial density or to proton leak. Mechanistically, part of the p50(mito) seems to be controlled by the excess of cytochrome c oxidase (COX) protein and activity relative to other mitochondrial proteins. This is illustrated by the 5-fold increase in p50(mito) after partial cyanide inhibition of COX at doses that do not affect maximal mitochondrial electron flux through the ETS. These data suggest that the interindividual variation in BMR in humans is primarily explained by differences in mitochondrial oxygen affinity. The implications of these findings are discussed in terms of a trade-off between aerobic efficiency and power.

Journal article (other academic/artistic)abstract
- The purpose of this study was to compare effects on rat bone and uterus of estrogen depletion and exposure to the coplanar PCB-congener 3,3',4,4',5-pentachlorobiphenyl (PCB #126) which exhibits anti-estrogenic properties. Half of the rats were ovariectomized (n = 20) and the other half were sham-operated. Ten of the ovariectomized rats and ten of the sham operated were exposed to PCB #126 (ip injections) for 3 months (total dose: 384 microgram/kg body wt). The remaining control rats were injected with corn oil (vehicle). The rats were killed and the tibiae and uteri were dissected. The left tibia was used for measurements of weight, length, and bone mineral density and the right for histomorphometrical analysis. The uteri were analyzed with respect to estrogen receptor content. PCB #126 exposure did not affect bone mineral density or trabecular bone volume of tibia in sham-operated rats. In ovariectomized rats PCB #126 exposure resulted in a decreased length and an increased bone mineral density of tibia. An obvious PCB #126 induced increase in osteoid surface was observed in sham-operated rats. The cortical thickness and the organic content of the tibia were also increased in these rats. In estrogen deprived tissue like the uteri of ovariectomized rats, PCB #126 showed weak estrogen agonistic activity. The observed effects of PCB #126 on bone and uterine tissues differed between ovariectomized and sham-operated rats.
