[Willingness of Psychotherapists in Private Practice to Treat Patients With Complex Post-Traumatic Stress and Dissociative Disorders]

OBJECTIVE

Analyses of patient care with severe mental disorders.

METHODS

Psychotherapists in private praxis were interviewed about their willingness to treat patients with a range of diagnoses in the context of post-traumatic disorders.

RESULTS

Therapists were found more willing to treat "less severe" disorders, independent of years in practice, school of psychotherapy, a rural or urban practice setting. Therapists criticized the quality of their training and the health insurance review process.

CONCLUSIONS

Therapists are generally willing to treat patients with severe mental disorders, but experience limits of competency attributed to training deficits. They further experience the bureaucratic procedures of the health insurance review process as barriers to accepting these patients into treatment.These results indicate that recently developed concepts of psychotherapy for these patient groups should be more intensively integrated into the existing training curricula. Furthermore, a simplified health insurance review process ought to be considered.

Cross-sectional assessment of neuromuscular function using mechanography in women and men aged 20-85 years

OBJECTIVES

The aim of this cross-sectional study was to examine the influence of age and sex on neuromuscular function of the lower limbs using mechanography. 704 adults aged 20-85 years from Germany participated in this study.

METHODS

Ground reaction force and power were assessed with countermovement jumps and the chair rising test on a ground reactions force plate.

RESULTS

While ground reaction force per unit body mass declined by about 20% from the third to the ninth decade, the decline of power per unit body mass was much greater, varying between 40-50%. Men and women are affected equally by the decline. Age and sex explained the variability of the power parameters to a much greater extent (R(2)=0.54 to R(2)=0.70) than the force parameters (R(2)=0.18 to R(2)=0.36).

CONCLUSIONS

Our reference values can help to identify those who might be affected by the development of sarcopenia. Preventive exercise programs should focus on preserving muscle power in addition to the training of muscle force.

Bone density and neuromuscular function in older competitive athletes depend on running distance

Individuals who are involved in explosive sport types, such as 100-m sprints and long jump, have greater bone density, leg muscle size, jumping height and grip strength than individuals involved in long-distance running.

INTRODUCTION

The purpose of this study is to examine the relationship between different types of physical activity with bone, lean mass and neuromuscular performance in older individuals.

METHODS

We examined short- (n = 50), middle- (n = 19) and long-distance (n = 109) athletes at the 15th European Masters Championships in Poznań, Poland. Dual X-ray absorptiometry was used to measure areal bone mineral density (aBMD) and lean tissue mass. Maximal countermovement jump, multiple one-leg hopping and maximal grip force tests were performed.

RESULTS

Short-distance athletes showed significantly higher aBMD at the legs, hip, lumbar spine and trunk compared to long-distance athletes (p ≤ 0.0012). Countermovement jump performance, hop force, grip force, leg lean mass and arm lean mass were greater in short-distance athletes (p ≤ 0.027). A similar pattern was seen in middle-distance athletes who typically showed higher aBMD and better neuromuscular performance than long-distance athletes, but lower in magnitude than short-distance athletes. In all athletes, aBMD was the same or higher than the expected age-adjusted population mean at the lumbar spine, hip and whole body. This effect was greater in the short- and middle-distance athletes.

CONCLUSIONS

The stepwise relation between short-, middle- and long-distance athletes on bone suggests that the higher-impact loading protocols in short-distance disciplines are more effective in promoting aBMD. The regional effect on bone, with the differences between the groups being most marked at load-bearing regions (legs, hip, spine and trunk) rather than non-load-bearing regions, is further evidence in support of the idea that bone adaptation to exercise is dependent upon the local loading environment, rather than as part of a systemic effect.

Changes in lower extremity muscle function after 56 days of bed rest

Preservation of muscle function, known to decline in microgravity and simulation (bed rest), is important for successful spaceflight missions. Hence, there is great interest in developing interventions to prevent muscle-function loss. In this study, 20 males underwent 56 days of bed rest. Ten volunteers were randomized to do resistive vibration exercise (RVE). The other 10 served as controls. RVE consisted of muscle contractions against resistance and concurrent whole-body vibration. Main outcome parameters were maximal isometric plantar-flexion force (IPFF), electromyography (EMG)/force ratio, as well as jumping power and height. Measurements were obtained before and after bed rest, including a morning and evening assessment on the first day of recovery from bed rest. IPFF (−17.1%), jumping peak power (−24.1%), and height (−28.5%) declined ( P < 0.05) in the control group. There was a trend to EMG/force ratio decrease (−20%; P = 0.051). RVE preserved IPFF and mitigated the decline of countermovement jump performance (peak power −12.2%; height −14.2%). In both groups, IPFF was reduced between the two measurements of the first day of reambulation. This study indicates that bed rest and countermeasure exercises differentially affect the various functions of skeletal muscle. Moreover, the time course during recovery needs to be considered more thoroughly in future studies, as IPFF declined not only with bed rest but also within the first day of reambulation. RVE was effective in maintaining IPFF but only mitigated the decline in jumping performance. More research is needed to develop countermeasures that maintain muscle strength as well as other muscle functions including power.

Evidence for an additional effect of whole-body vibration above resistive exercise alone in preventing bone loss during prolonged bed rest

SUMMARY

The addition of whole-body vibration to high-load resistive exercise may provide a better stimulus for the reduction of bone loss during prolonged bed rest (spaceflight simulation) than high-load resistive exercise alone.

INTRODUCTION

Prior work suggests that the addition of whole-body vibration to high-load resistive exercise (RVE) may be more effective in preventing bone loss in spaceflight and its simulation (bed rest) than resistive exercise alone (RE), though this hypothesis has not been tested in humans.

METHODS

Twenty-four male subjects as part of the 2nd Berlin Bed Rest Study performed RVE (n = 7), RE (n = 8) or no exercise (control, n = 9) during 60-day head-down tilt bed rest. Whole-body, spine and total hip dual X-ray absorptiometry (DXA) measurements as well as peripheral quantitative computed tomography measurements of the tibia were conducted during bed rest and up to 90 days afterwards.

RESULTS

A better retention of bone mass in RVE than RE was seen at the tibial diaphysis and proximal femur (p ≤ 0.024). Compared to control, RVE retained bone mass at the distal tibia and DXA leg sub-region (p ≤ 0.020), but with no significant difference to RE (p ≥ 0.10). RE impacted significantly (p = 0.038) on DXA leg sub-region bone mass only. Calf muscle size was impacted similarly by both RVE and RE. On lumbar spine DXA, whole-body DXA and calcium excretion measures, few differences between the groups were observed.

CONCLUSIONS

Whilst further countermeasure optimisation is required, the results provide evidence that (1) combining whole-body vibration and high-load resistance exercise may be more efficient than high-load resistive exercise alone in preventing bone loss at some skeletal sites during and after prolonged bed rest and (2) the effects of exercise during bed rest impact upon bone recovery up to 3 months afterwards.

The 2nd Berlin BedRest Study: protocol and implementation

Long-term bed-rest is used to simulate the effect of spaceflight on the human body and test different kinds of countermeasures. The 2nd Berlin BedRest Study (BBR2-2) tested the efficacy of whole-body vibration in addition to high-load resisitance exercise in preventing bone loss during bed-rest. Here we present the protocol of the study and discuss its implementation. Twenty-four male subjects underwent 60-days of six-degree head down tilt bed-rest and were randomised to an inactive control group (CTR), a high-load resistive exercise group (RE) or a high-load resistive exercise with whole-body vibration group (RVE). Subsequent to events in the course of the study (e.g. subject withdrawal), 9 subjects participated in the CTR-group, 7 in the RVE-group and 8 (7 beyond bed-rest day-30) in the RE-group. Fluid intake, urine output and axiallary temperature increased during bed-rest (p < .0001), though similarly in all groups (p > or = .17). Body weight changes differed between groups (p < .0001) with decreases in the CTR-group, marginal decreases in the RE-group and the RVE-group displaying significant decreases in body-weight beyond bed-rest day-51 only. In light of events and experiences of the current study, recommendations on various aspects of bed-rest methodology are also discussed.

Resistive vibration exercise attenuates bone and muscle atrophy in 56 days of bed rest: biochemical markers of bone metabolism

During and after prolonged bed rest, changes in bone metabolic markers occur within 3 days. Resistive vibration exercise during bed rest impedes bone loss and restricts increases in bone resorption markers whilst increasing bone formation.

INTRODUCTION

To investigate the effectiveness of a resistive vibration exercise (RVE) countermeasure during prolonged bed rest using serum markers of bone metabolism and whole-body dual X-ray absorptiometry (DXA) as endpoints.

METHODS

Twenty healthy male subjects underwent 8 weeks of bed rest with 12 months follow-up. Ten subjects performed RVE. Blood drawings and DXA measures were conducted regularly during and after bed rest.

RESULTS

Bone resorption increased in the CTRL group with a less severe increase in the RVE group (p = 0.0004). Bone formation markers increased in the RVE group but decreased marginally in the CTRL group (p < 0.0001). At the end of bed rest, the CTRL group showed significant loss in leg bone mass (-1.8(0.9)%, p = 0.042) whereas the RVE group did not (-0.7(0.8)%, p = 0.405) although the difference between the groups was not significant (p = 0.12).

CONCLUSIONS

The results suggest the countermeasure restricts increases in bone resorption, increased bone formation, and reduced bone loss during bed rest.

Decline of specific peak jumping power with age in master runners

BACKGROUND

It is difficult to disentangle the effects of pure ageing from those of disuse. Master athletes, however, provide an opportunity to assess the effects of ageing per se, as these people maintain high activity levels during ageing.

METHODS

We examined 200 female and 295 male master runners over the age of 35 who participated at European and World master championships. Runners were grouped by short, middle and long distance disciplines. Besides a questionnaire about their sports activities, measurements of counter movement jumps on a ground reaction force plate were performed. Specific peak jump power was the main subject, i.e., maximum jump power per body mass.

RESULTS

All discipline groups showed an age-related decline in specific jump power when performing counter movement jumps (p<0.001). Except for female long distance runners, the amount of decline was the same for all discipline groups (p<0.001 to p<0.01) for each gender. The results for female long distance runners was highly spread caused by the small number of participants with older age.

CONCLUSIONS

Our data indicate a decline in specific jump power that is similar to that reported in previous studies. The novelty from our results is the comparison of intra-gender decline. We observed the same amount of decline for all runners participating in different running disciplines.

Highly Demanding Resistive Vibration Exercise Program is Tolerated During 56 Days of Strict Bed-Rest

Several studies have tried to find countermeasures against musculoskeletal de-conditioning during bed-rest, but none of them yielded decisive results. We hypothesised that resistive vibration exercise (RVE) might be a suitable training modality. We have therefore carried out a bed-rest study to evaluate its feasibility and efficacy during 56 days of bed-rest. Twenty healthy male volunteers aged 24 to 43 years were recruited and, after medical check-ups, randomised to a non-exercising control (Ctrl) group or a group that performed RVE 11 times per week. Strict bed-rest was controlled by video surveillance. The diet was controlled. RVE was performed in supine position, with a static force component of about twice the body weight and a smaller dynamic force component. RVE comprised four different units (squats, heel raises, toe raises, kicks), each of which lasted 60 - 100 seconds. Pre and post exercise levels of lactate were measured once weekly. Body weight was measured daily on a bed scale. Pain questionnaires were obtained in regular intervals during and after the bed-rest. Vibration frequency was set to 19 Hz at the beginning and progressed to 25.9 Hz (SD 1.9) at the end of the study, suggesting that the dynamic force component increased by 90 %. The maximum sustainable exercise time for squat exercise increased from 86 s (SD 21) on day 11 of the BR to 176 s (SD 73) on day 53 (p = 0.006). On the same days, post-exercise lactate levels increased from 6.9 mmol/l (SD2.3) to 9.2 mmol/l (SD 3.5, p = 0.01). On average, body weight was unchanged in both groups during bed-rest, but single individuals in both groups depicted significant weight changes ranging from - 10 % to + 10 % (p < 0.001). Lower limb pain was more frequent during bed-rest in the RVE subjects than in Ctrl (p = 0.035). During early recovery, subjects of both groups suffered from muscle pain to a comparable extent, but foot pain was more common in Ctrl than in RVE (p = 0.013 for plantar pain, p = 0.074 for dorsal foot pain). Our results indicate that RVE is feasible twice daily during bed-rest in young healthy males, provided that one afternoon and one entire day per week are free. Exercise progression, mainly by progression of vibration frequency, yielded increases in maximum sustainable exercise time and blood lactate. In conclusion, RVE as performed in this study, appears to be safe.

Prevalence of dissociative disorders among psychiatric inpatients in a German university clinic

The aim of the study was to determine the frequency of dissociative disorders among psychiatric inpatients in Germany and to investigate the relationship between childhood trauma and dissociation. The German version of the Dissociative Experiences Scale (DES), the Fragebogen für Dissoziative Symptome (FDS), was used to screen 115 consecutive inpatients admitted to the psychiatric clinic of a university hospital. Patients with FDS scores higher than 20 were interviewed by a trained clinician, using the German translation of the Structured Clinical Interview for DSM-IV Dissociative Disorders (SCID-D-R). The German version of the Childhood Trauma Questionnaire (CTQ) was administered to investigate prevalence of childhood trauma and relations between childhood trauma and dissociation in adult life. Twenty-five of the 115 patients (21.7%) had a score higher than 20 on the FDS. Of these, 15 patients were interviewed with the SCID-D-R. One patient was diagnosed with a dissociative identity disorder, three with dissociative disorders not otherwise specified, and one patient with depersonalization disorder. All diagnoses were confirmed clinically. A significant positive relationship was found between the severity of childhood trauma and dissociation. Dissociative disorders are common among German psychiatric inpatients. Clinicians who work in psychiatric inpatient units should be mindful of these disorders.

[Radiologic follow-up of the thoracic organs in intensive care patients. The value of the thoracic picture correlated with the clinical and biochemical findings]

Correlation between chest radiographs and clinical indicators was studied in 212 patients in intensive care. 1. There was good correlation between raised pulmonary artery pressure and radiological signs of left heart insufficiency, but not with the value of central venous pressure. 2. Fever and leukocytosis nearly always precede radiological evidence of pneumonia; their persistence does not necessarily indicate persistent pneumonia. 3. Pneumonias, effusions, atelectases and emboli are more common on the right. 4. More than 70% of central venous catheters were incorrectly placed; most commonly, the catheter was placed too low. Life-threatening complications occurred in 1.3%.

[Social psychiatric traditions between the empire period and national socialism]

From the time psychiatry had become a scientific discipline in its own right, sociopsychiatric efforts have been directed towards erecting a second outpatient care pillar in the psychiatric patient care setup to make up for the drawbacks of oversize psychiatric hospitals that were the problematic heritage of erstwhile Prussia. During the period of the German Empire under Kaiser William II these efforts were not honored by the state. This started, with serious consequences, a vicious circle of institutionalising mentally deranged patients, a procedure that seemed to inflate the incidence of these diseases to the dimensions of a menace and hence created a fertile soil for the axioms of "reacial hygiene" to take root. The Bavarian psychiatrist Gustav Kolb (1870-1938), who realised how much of this development was really "home made", demanded in 1908--pursuing and expanding the ideas of that paradigmatic scientist and first sociopsychiatrist, Wilhelm Griesinger (1817-1868)--once again to recognise psychiatric care by setting up a second outpatient pillar in the form of an "Open Public Welfare Service" attached to a relevant psychiatric hospital. However, the full significance of his reformatory proposals was not realised at that time. When finally open public welfare was translated into reality during 1918-1933 as a result of the zealous efforts on the part of the reformatory psychiatrists, this was mainly done to save cost, whereas Kolb's original aims were largely lost in the process.(ABSTRACT TRUNCATED AT 250 WORDS)
