Opening toward life: experiences of basic body awareness therapy in persons with major depression

Although there is a vast amount of research on different strategies to alleviate depression, knowledge of movement-based treatments focusing on body awareness is sparse. This study explores the experiences of basic body awareness therapy (BBAT) in 15 persons diagnosed with major depression who participated in the treatment in a randomized clinical trial. Hermeneutic phenomenological methodology inspired the approach to interviews and data analysis. The participants’ experiences were essentially grasped as a process of enhanced existential openness, opening toward life, exceeding the tangible corporeal dimension to also involve emotional, temporal, and relational aspects of life. Five constituents of this meaning were described: vitality springing forth, grounding oneself, recognizing patterns in one's body, being acknowledged and allowed to be oneself, and grasping the vagueness. The process of enhanced perceptual openness challenges the numbness experienced in depression, which can provide hope for change, but it is connected to hard work and can be emotionally difficult to bear. Inspired by a phenomenological framework, the results of this study illuminate novel clinical and theoretical insight into the meaning of BBAT as an adjunctive approach in the treatment of depression.

Exercise or basic body awareness therapy as add-on treatment for major depression: a controlled study

BACKGROUND

While physical exercise as adjunctive treatment for major depression has received considerable attention in recent years, the evidence is conflicting. This study evaluates the effects of two different add-on treatments: exercise and basic body awareness therapy.

METHODS

Randomized controlled trial with two intervention groups and one control, including 62 adults on antidepressant medication, who fulfilled criteria for current major depression as determined by the Mini International Neuropsychiatric Interview. Interventions (10 weeks) were aerobic exercise or basic body awareness therapy (BBAT), compared to a single consultation with advice on physical activity. Primary outcome was depression severity, rated by a blinded assessor using the Montgomery Asberg Rating Scale (MADRS). Secondary outcomes were global function, cardiovascular fitness, self-rated depression, anxiety and body awareness.

RESULTS

Improvements in MADRS score (mean change=-10.3, 95% CI (-13.5 to -7.1), p=0.038) and cardiovascular fitness (mean change=2.4ml oxygen/kg/min, 95% CI (1.5 to 3.3), p=0.017) were observed in the exercise group. Per-protocol analysis confirmed the effects of exercise, and indicated that BBAT has an effect on self-rated depression.

LIMITATIONS

The small sample size and the challenge of missing data. Participants׳ positive expectations regarding the exercise intervention need to be considered.

CONCLUSIONS

Exercise in a physical therapy setting seems to have effect on depression severity and fitness, in major depression. Our findings suggest that physical therapy can be a viable clinical strategy to inspire and guide persons with major depression to exercise. More research is needed to clarify the effects of basic body awareness therapy.

Exercise in the treatment of major depression: a systematic review grading the quality of evidence

OBJECTIVE

To examine the quality of evidence for exercise in the treatment of major depression, comparing specific study types; aerobic exercise vs. antidepressants, aerobic exercise vs. any physical activity, and aerobic exercise as augmentation therapy to treatment as usual vs. treatment as usual.

METHODS

Electronic searches for randomized controlled studies, reporting on treatment outcome in adults with major depression confirmed by a clinical interview. Quality of evidence was assessed using the Grading and Recommendations Assessment, Development and Evaluation and an additional risk of bias-protocol.

RESULTS

Fourteen eligible studies were retrieved, of which nine had low risk of bias. We found moderate quality of evidence that aerobic exercise has no significant effect compared to antidepressants. We found moderate quality of evidence that aerobic exercise at a moderate to high intensity has no significant effect compared to other forms of physical activity. We found low quality of evidence that exercise as augmentation to treatment as usual has a small effect - depression scores were on average 0.44 of a standard deviation lower - compared to treatment as usual.

CONCLUSION

In general, exercise appears to be beneficial in the treatment of depression when used in combination with medication. A significant issue that is not well addressed in previous studies is the risks associated with exercise. Further, this review indicates that aerobic exercise is not more effective than other types of physical activity, pointing to a need to further investigate active components.

Children with screening-detected coeliac disease show increased levels of nitric oxide products in urine

AIM

Increased concentration of nitric oxide (NO) metabolites, nitrite and nitrate, in the urine is a strong indication of ongoing small intestinal inflammation, which is a hallmark of the enteropathy of coeliac disease (CD). It has previously been shown that children with symptomatic, untreated CD have increased levels of NO oxidation products in their urine. The aim of this study was to investigate whether screening-detected, asymptomatic coeliac children display the same urinary nitrite/nitrate pattern.

METHODS

In a multicenter screening study, serum samples were collected from 7208 12-year-old children without previously diagnosed CD. Sera were analysed for anti-human tissue transglutaminase (tTG) of isotype IgA. Small bowel biopsy was performed in antibody-positive children, yielding 153 new cases of CD. In the screening-detected individuals, the sum of nitrite and nitrate concentrations in the urine was analysed and used as an indicator of NO production. For comparison, 73 children with untreated, symptomatic CD were studied.

RESULTS

The nitrite/nitrate levels in children with screening-detected CD and those with untreated symptomatic CD did not differ significantly. Both groups had significantly increased urinary nitrite/nitrate concentrations compared to the children with normal small bowel biopsy (p < 0.001).

CONCLUSION

  Children with screening-detected CD have increased production of NO just as children with untreated symptomatic CD. High NO metabolite levels in the urine may indicate a pathogenetic feature of CD and be a marker of major clinical importance.

Small bowel biopsy in Swedish paediatric clinics

AIM

A correct diagnosis of coeliac disease, one of the most common chronic diseases in Swedish children, demands small bowel biopsy, which can be performed endoscopically or by means of a peroral capsule. Recently there was a debate among Swedish paediatric gastroenterologists, with some advocating the cessation of capsule biopsy in favour of endoscopic biopsies. To gain information on which to base a recommendation for which technique to use, the Swedish Working Group for Childhood Coeliac Disease was commissioned to carry out a national questionnaire study on current small bowel biopsy routines in Swedish paediatric clinics.

METHODS

A questionnaire concerning biopsy routines in the year 2000 was sent to all paediatric clinics performing biopsies. A reply was obtained from 39 of 40 clinics, covering 98% of the Swedish population.

RESULTS

Some 1400 biopsies were performed, 64% of which were capsule biopsies and 36% endoscopic. Three clinics performed all biopsies endoscopically and 11 clinics all via a capsule. At endoscopy all children were under deep sedation or full anaesthesia, while most children undergoing capsule biopsy were under light or deep sedation. The oxygen saturation was monitored during endoscopy but less often or never during routine capsule biopsy. The presence of the parents during biopsy varied according to the degree of sedation: at 97% of the clinics performing capsule biopsy on children under light sedation, the parents were present during the whole procedure, whereas no parents were present at clinics where the biopsy was performed endoscopically under anaesthesia.

CONCLUSION

Compared with the results of a similar questionnaire concerning biopsy routines performed in the early 1990s, children are now more effectively sedated. Furthermore, there is an obvious trend from capsule towards endoscopic biopsy. Both the endoscopic and the capsule biopsy techniques are useful and satisfactory for obtaining small bowel mucosal samples providing that the children are effectively sedated. For practical and economic reasons the capsule biopsy technique will probably continue to be used, although to a lesser extent than today.

A central core structure in an antibody variable domain determines antigen specificity

Antibody binding sites provide an adaptable surface capable of interacting with essentially any molecular target. Using CDR shuffling, residues important for the assembly of mucin-1 specific paratopes were defined by random recombination of the complementarity determining regions derived from a set of mucin-1 specific clones, previously selected from an antibody fragment library. It was found that positions 33 and 50 in the heavy chain and 32, 34, 90, 91 and 96 in the light chain were conserved in many of the clones. These particular residues seem to be located centrally in the binding site as indicated by a structure model analysis. The importance of several of these conserved residues was supported by their presence in a mouse monoclonal antibody with a known structure and the same epitope specificity. Several of these corresponding residues in the mouse monoclonal antibody are known to interact with the antigen. In conclusion, critical residues important for maintaining a human antigen-specific binding site during the process of in vitro antibody evolution were defined. Furthermore, an explanation for the observed restricted germline gene usage in certain antibody responses against protein epitopes is provided.

Recombining germline-derived CDR sequences for creating diverse single-framework antibody libraries

We constructed a single-chain Fv antibody library that permits human complementarity-determining region (CDR) gene fragments of any germline to be incorporated combinatorially into the appropriate positions of the variable-region frameworks VH-DP47 and VL-DPL3. A library of 2 x 109 independent transformants was screened against haptens, peptides, carbohydrates, and proteins, and the selected antibody fragments exhibited dissociation constants in the subnanomolar range. The antibody genes in this library were built on a single master framework into which diverse CDRs were allowed to recombine. These CDRs were sampled from in vivo-processed gene sequences, thus potentially optimizing the levels of correctly folded and functional molecules, and resulting in a molecule exhibiting a lower computed immunogenicity compared to naive immunoglobulins. Using the modularized assembly process to incorporate foreign sequences into an immunoglobulin scaffold, it is possible to vary as many as six CDRs at the same time, creating genetic and functional variation in antibody molecules.

Late-diagnosed DDH: a prospective 11-year follow-up of 71 consecutive patients (75 hips)

I have prospectively studied 71 consecutive patients (75 hips) with late-diagnosed DDH (developmental dysplasia of the hip) treated uniformly with special reference to the development of the femoral head and the acetabulum. The age at the start of treatment was 10 (2-64) months. The follow-up time was 11 (6-18) years. After tenotomy and traction, closed reduction failed in 7 hips. These cases were treated by open reduction with or without Salter innominate osteotomy-in 2 hips femoral osteotomy was also done (shortening, varus and derotation). 1 hip subluxated and 1 re-dislocated after closed reduction. Avascular necrosis occurred in 4 hips and additional surgery was required in 12 hips--11 Salter osteotomies, 1 varus femoral osteotomy. In the first year after reduction, the acetabular angle improved rapidly--faster in the younger children. When treatment started between 12 and 22 months, the improvement was slower and the final outcome more unpredictable. The femoral head continued to grow irrespective of the age at reduction and became normal in almost all cases. Salter's innominate osteotomy stabilized hips after open reduction and gave excellent results in cases with an increasing acetabular angle. At the last re-examination, all but 2 patients were asymptomatic. Radiographically, 65 hips were rated Severin group I, 9 group II and 1 group III.

Epidemic of coeliac disease in Swedish children

Coeliac disease has emerged as a public health problem. The aim of the present study was to analyse trends in the occurrence of symptomatic coeliac disease in Swedish children from 1973 to 1997, and to explore any temporal relationship to changes in infant dietary patterns. We established a population-based prospective incidence register of coeliac disease in 1991, and, in addition, retrospective data from 1973 were collected. A total of 2151 cases fulfilled the diagnostic criteria. Furthermore. We collected national data on a yearly basis on duration of breastfeeding, intake of gluten-containing cereals and recommendations on when and how to introduce gluten into the diet of infants. From 1985 to 1987 the annual incidence rate in children below 2 y of age increased fourfold to 200-240 cases per 100000 person years, followed from 1995 by a sharp decline to the previous level of 50-60 cases per 100000 person years. This epidemic pattern is quite unique for a chronic disease of immunological pathogenesis, suggesting that prevention could be possible. The ecological observations made in this study are compatible with the epidemic being the result, at least in part, of a change in and an interplay among three factors within the area of infant feeding, i.e. amount of gluten given, age at introduction of gluten, and whether breastfeeding was ongoing or not when gluten was introduced. Other factor(s) may also have contributed, and the search for these should be intensified.

Cystatin F is a glycosylated human low molecular weight cysteine proteinase inhibitor

A previously undescribed human member of the cystatin superfamily called cystatin F has been identified by expressed sequence tag sequencing in human cDNA libraries. A full-length cDNA clone was obtained from a library made from mRNA of CD34-depleted cord blood cells. The sequence of the cDNA contained an open reading frame encoding a putative 19-residue signal peptide and a mature protein of 126 amino acids with two disulfide bridges and enzyme-binding motifs homologous to those of Family 2 cystatins. Unlike other human cystatins, cystatin F has 2 additional Cys residues, indicating the presence of an extra disulfide bridge stabilizing the N-terminal region of the molecule. Recombinant cystatin F was produced in a baculovirus expression system and characterized. The mature recombinant protein processed by insect cells had an N-terminal segment 7 residues longer than that of cystatin C and displayed reversible inhibition of papain and cathepsin L (Ki = 1.1 and 0.31 nM, respectively), but not cathepsin B. Like cystatin E/M, cystatin F is a glycoprotein, carrying two N-linked carbohydrate chains at positions 36 and 88. An immunoassay for quantification of cystatin F showed that blood contains low levels of the inhibitor (0.9 ng/ml). Six B cell lines in culture secreted barely detectable amounts of cystatin F, but several T cell lines and especially one myeloid cell line secreted significant amounts of the inhibitor. Northern blot analysis revealed that the cystatin F gene is primarily expressed in peripheral blood cells and spleen. Tissue expression clearly different from that of the ubiquitous inhibitor, cystatin C, was also indicated by a high incidence of cystatin F clones in cDNA libraries from dendritic and T cells, but no clones identified by expressed sequence tag sequencing in several B cell libraries and in >600 libraries from other human tissues and cells.

[Proposed criteria for diagnosis of celiac disease in children]

At a seminar arranged in September 1997 by the Swedish Paediatric Working Group for Coeliac Disease, a diagnostic protocol proposed by the working group was approved by a majority of the paediatricians present, representing almost all paediatric units in Sweden. Briefly, a small bowel biopsy is called for in all children, both at presentation and as a control during gluten-free dieting. Subsequent gluten challenge and biopsy are mandatory only in cases of atypical presentation or if the diagnosis is questioned at some future date. Serum antigliadin and anti-endomysial antibody tests are complementary tools. Agreement was also reached regarding the institution of a national coeliac disease registry.

Prevalence of coxarthrosis in an urban population during four decades

In the current study, in a survey of 4121 double contrast radiographs of the colon performed from 1987 through 1995, the hip joints were examined and classified with regard to the presence or absence of primary coxarthrosis. The data collection was performed in precisely the same manner as in two earlier studies undertaken on 3903 radiographs of the colon covering the years 1956 through 1962 and 4027 radiographs of the colon covering the years 1975 through 1982. In the current study the prevalence of coxarthrosis, the gender ratio, and distribution between bilateral and unilateral cases had not changed compared with the data from the two earlier studies. When pooling the three investigations, the age specific prevalence of primary coxarthrosis based on the 12,051 radiographs fits an exponential curve for which the prevalence of primary coxarthrosis increased from below 1% in the age group younger than 55 years to 10% in the age group older than 85 years. In the current study approximately half of the patients (55%) had undergone total hip arthroplasty. This was more than in the study from 1984 (35%). Among the surgically treated patients, lateral coxarthrosis was more common than was medial coxarthrosis.

Small bowel biopsy in Swedish paediatric clinics

The capsule technique for small bowel biopsy performed at Swedish paediatric clinics was evaluated using two questionnaires in 1990 and 1993, respectively. Replies were received from all 45 centres which together perform approximately 2300 biopsies per year. Clotting function tests prior to biopsy were carried out in 42% of the centres. The biopsies were performed under intubation anaesthesia in 13% of the centres. The most striking difference between the answers to the two questionnaires was the mode of sedation. The use of intravenous sedatives increased from 40% of the centres in the first questionnaire to 59% in the second one. The use of the oral, rectal and intramuscular routes decreased correspondingly. The most frequently used drugs for intravenous sedation were benzodiazepines, in the first questionnaire diazepam and in the second one midazolam. The failure rate was approximately 5%. In the first questionnaire, no complication was encountered. In the second questionnaire, three cases of intramural duodenal haematoma were reported, one of which led to pancreatitis. We conclude that by focusing on questions of sedation these rather simple questionnaires may have resulted in more effective sedation of children undergoing small bowel biopsy.

Induction of primary antigen-specific immune reponses in SCID-hu-PBL by coupled T-B epitopes

Adoptive transfer of human lymphoid cells into immunodeficient (SCID) mice lacking the ability to functionally rearrange T- and B-cell receptor genes constitutes a unique model to study and manipulate human immunocytes. We have investigated this model for the purpose of generating an antigen-specific primary humoral immune response. Peripheral blood lymphocytes (PBL) derived from blood donors were used to repopulate SCID mice, which subsequently were immunized with different B-cell epitopes coupled to either tetanus toxoid (TT), or to a promiscuous helper epitope of TT, or by incorporating the antigens into a liposome construct. By recruiting the necessary T-cell help found in the T-cell memory compartment against TT, primary immune responses were obtained against the hapten dinitrophenyl (DNP), the V3 loop peptide derived from glycoprotein (gp120) (HIV-1), the melanoma-associated GD2 ganglioside and ovine submaxillary mucin. The primary immune response against the GD2 ganglioside was induced by incapsulating TT into GD2-containing liposomes. These liposome constructs also allowed us to induce a high human IgG serotitre (3000-4000) against this normally not very immunogenic ganglioside.

Sequence determination of variable region genes of two human monoclonal antibodies against Neisseria meningitidis

Nucleotide sequences for the variable regions of both the heavy and light chains for two human monoclonal antibodies have been determined. Both antibodies are directed against an outer membrane protein of Neisseria meningitidis, and their genes show a low resemblance to germline sequences.
