Abstract
INTRODUCTION Among U.S. military active duty service members, cervicalgia, cervical radiculopathy, and myelopathy are common causes of disability, effecting job performance and readiness, often leading to medical separation from the military. Among surgical therapies, anterior cervical discectomy and fusion (ACDF) and cervical disc arthroplasty (CDA) are options in select cases; however, elective surgeries performed while serving overseas (OCONUS) have not been studied. MATERIALS AND METHODS A retrospective analysis of a prospectively collected surgical database from an OCONUS military treatment facility over a 2-year period (2019-2021) was queried. Patient and procedural data were collected to include ACDF or CDA surgery, military rank, age, tobacco use, pre- and post-operative visual analogue scales for pain, and presence of radiographic fusion after surgery for ACDF patients or heterotopic ossification for CDA patients. Chi-square and Student t-test analyses were performed to identify variables associated with return to full duty. RESULTS A total of 47 patients (25 ACDF and 22 CDA) underwent surgery with an average follow-up of 192.1 days (range 7-819 days). Forty-one (87.2%) patients were able to return to duty without restrictions; 10.6% of patients remained on partial or limited duty at latest follow-up and one patient was medically separated from the surgical cohort. There was one complication and one patient required tour curtailment from overseas duty for ongoing symptoms. CONCLUSIONS Both ACDF and CDA are effective and safe surgical procedures for active duty patients with cervicalgia, cervical radiculopathy, and cervical myelopathy. They can be performed OCONUS with minimal interruption to the patient, their family, and the military unit, while helping to maintain surgical readiness for the surgeon and the military treatment facility.

Abstract
Little is known on why adherence to follow-up care in childhood cancer survivors (CCS) is lacking. This study characterized barriers to adherence to follow-up care among CCS, identified sociodemographic correlates of barriers, and examined whether barriers to follow-up care relate to health-related quality of life. Adult CCS (N=84) were anonymously surveyed via REDCap using the Barriers to Care Questionnaire (BCQ) and the Quality of Life Scale-Cancer Survivor (QOL-CS). Both descriptive and correlation analyses were conducted. The median BCQ total score was 88.5 (interquartile ranges:78.4 to 95.7), with the greatest barriers reported in the Skills (eg, ease of navigating the healthcare system) and Pragmatism subscales (eg, cost). There was a statistically significant correlation between the BCQ total score and the QOL-CS total score (rs=0.47, P <0.0001) and the physical, psychological, and social QOL-CS subscales (all P 's<0.05). The results found that barriers to follow-up care for CCS are mostly related to cost and appointment logistics, and that more barriers to care is associated with lower health-related quality of life among CCS. Identifying barriers to follow-up care is the first step in improving adherence, which would allow for earlier detection of late effects of cancer therapy and thereby result in reductions in morbidity and mortality.

Abstract
Background MRI (magnetic resonance imaging) using low-magnet field strength has unique advantages for intraoperative use. We compared a novel, compact, portable MR imaging system to an established intraoperative 0.15 T system to assess potential utility in intracranial neurosurgery. Methods Brain images were acquired with a 0.15 T intraoperative MRI (iMRI) system and a 0.064 T portable MR system. Five healthy volunteers were scanned. Individual sequences were rated on a 5-point (1 to 5) scale for six categories: contrast, resolution, coverage, noise, artifacts, and geometry. Results Overall, the 0.064 T images (M = 3.4, SD = 0.1) had statistically higher ratings than the 0.15 T images (M = 2.4, SD = 0.2) ( p < 0.01). All comparable sequences (T1, T2, T2 FLAIR and SSFP) were rated significantly higher on the 0.064 T and were rated 1.2 points (SD = 0.3) higher than 0.15 T scanner, with the T2 fluid-attenuated inversion recovery (FLAIR) sequences showing the largest increment on the 0.064 T with an average rating difference of 1.5 points (SD = 0.2). Scanning time for the 0.064 T system obtained images more quickly and encompassed a larger field of view than the 0.15 T system. Conclusions A novel, portable 0.064 T self-shielding MRI system under ideal conditions provided images of comparable quality or better and faster acquisition times than those provided by the already well-established 0.15 T iMR system. These results suggest that the 0.064 T MRI has the potential to be adapted for intraoperative use for intracranial neurosurgery.

Abstract
Recent studies, mostly performed on bulimic outpatients, did not find consistent predictors of treatment outcome in bulimia nervosa. This is the first study to investigate anamnestic and clinical factors predictive of the short-term outcome of hospital treatment in 31 female bulimia nervosa patients with a mean age of 22.9 yr. Treatment outcome was assessed by several self-rating instruments measuring different features of the specific and unspecific psychopathology of bulimia nervosa. The most relevant predictors of the outcome of the 8-week hospital treatment were duration of previous inpatient treatments for bulimia, the intensity of anorexic tendency and the pretreatment level of depression. The majority of predictors tested did not show a strong relationship to treatment outcome. The findings are discussed in relation to results of other studies as well as to possible implications for treatment and research.

Abstract
The acute effects of dexfenfluramine on nocturnal sleep were studied in ten healthy male subjects by means of sleep EEG recordings and ratings of subjective sleep quality. Four different dosages (3 mg, 7 mg, 15 mg, and 30 mg) were tested, administered over a period of 3 days each. Under 15 mg and 30 mg dexfenfluramine, only slight effects on sleep were observed: 15 mg led to decreased sleep efficiency in the first night of medication, and to reduced percentage of slow wave sleep in the first and third night. A significant lengthening of REM latency was present in the third night under 30 mg dexfenfluramine, without changes in other REM sleep parameters. Daily doses of 3 mg and 7 mg dexfenfluramine did not influence sleep, except for a significant REM latency reduction observed in the first night under 3 mg. Apart from a transient slight impairment under 30 mg, ratings of subjective sleep quality did not mirror any impact of dexfenfluramine. The data suggest that therapeutic dosages of dexfenfluramine only slightly influence nocturnal sleep, which contrasts with the known impact of other anti-obesity agents like the amphetamines. Unlike classical antidepressants, dexfenfluramine does not reduce REM sleep; in light of a hypothetical link between REM sleep reduction and antidepressant action of a drug, dexfenfluramine is not expected to have a pronounced antidepressant effect.

Abstract
The effects of 19 meals of different caloric content on slides on palatability and hypothetical duration of consumption were investigated in 7 patients with anorexia nervosa, 17 patients with bulimia nervosa at the beginning and after 8 weeks of hospital treatment. Nine healthy females served as controls. At the beginning of treatment, palatability of low caloric food was significantly higher and hypothetical duration of consumption of high caloric food was significantly longer in patients when compared to controls. After 8 weeks, in the patients palatability of low caloric food had decreased. Dislike for high caloric food remained stable in anorexics.

Abstract
Stable attitudes towards illness and treatment and a high compliance with a 5-week low dose neuroleptic treatment (with/without anticonvulsant adjuvant therapy) were observed in 18 inpatients with schizophrenic disorders (ICD-9, DSM-III-R). Patients having previously received neuroleptics showed more compliant attitudes and greater satisfaction with the treatment, and complained less often about side effects. Noncompliant attitudes were related to dissatisfaction with treatment and self-rated depressed mood. Results of this pilot study are discussed, considering methodological problems and possible therapeutic implications.

Abstract
Cognitive behavior therapy was applied to 8 inpatients with bulimia (DSM-III). Improvement of bulimia was superior when compared to 6 bulimics treated with nonspecific psychotherapy. Social maladjustment was linked to the maintenance of bulimia. The effectiveness of cognitive behavior therapy seemed to be impaired by co-morbidity and dysphoric mood. Therefore a more structured externally controlled behavioral hospital treatment program is recommended.

Abstract
Hypercortisolism in depression has been extensively studied during the last three decades. The main hypothesis regarding origin and clinical relevance of this phenomenon, however, has changed significantly. Up to the mid-seventies hypercortisolism was conceived as consequence of stress modified by the degree of unconscious defense mechanisms in different forms of depressive or non-depressive psychiatric disorders. At the end of the seventies this point of view changed considerably. Hypercortisolism was regarded as a biological statemarker of the endogenous subtype of depression with clinical differential-diagnostic relevance. An abnormal dexamethasone suppression test (DST) was assumed to be the best indication of increased activation of the cortisol system. These conclusions turned out to be wrong. DST results are not specific for melancholia and the test seems to be of limited value for measuring the function of the HPA-axis. Intervening variables, such as weight loss, drug and alcohol withdrawal or situational stress, influence the test results significantly, independent of the nosological classification. Additionally, interindividual differences in the susceptibility of the HPA-axis may decisively influence the the activation of the HPA-axis as well in healthy subjects under stress as in psychiatric patients.

Abstract
This study, aimed at clarifying some methodological problems of the hCRF stimulation test, was performed on 12 healthy male volunteers. ACTH and cortisol increases after 30 min and their maximum increase proved to be highly reliable response parameters for the net area under the response curve of both hormones. An influence of baseline hormone values on the maximum response was apparent for cortisol but not for ACTH. Cortisol, but not ACTH, revealed a stable test-retest reliability. There were no correlations between ACTH and cortisol responses to hCRF.

Abstract
Studies on personality traits and coping styles as determinants of interindividual differences in neuroendocrine responses to stress have not yet yielded conclusive results. In a previous investigation, strong hints to distinct interindividual differences in the susceptibility of the HPA axis of 12 male volunteers aged 27 +/- 5 years exposed to five different stress situations were found. In the present report, psychometric variables (personality traits and coping styles) assessed in the same subjects before the study were analyzed to test whether specific psychometric variables were related to the interindividual differences in the susceptibility of the HPA axis. The results revealed that interindividual differences in the frequency of cortisol responses to stress situations could not be predicted by any of the psychometric variables investigated. The question if psychological factors contribute to neuroendocrine stress response and to what degree warrants further interest. These preliminary findings suggest, however, that nonpsychological factors should be considered more seriously as determinants of interindividual differences in neuroendocrine stress responses in healthy subjects as well as in psychiatric patients.

Abstract
Several treatment modalities, especially behaviour therapy, had been successfully administered in order to normalize body weight in anorexia nervosa inpatients. However, improvement in affective, cognitive and psychosocial features and associated psychopathologic symptoms was rather poor. It is hypothesized that the limited effect of behaviour therapy may be also due to therapeutic shortcomings of the behavioural treatment programme. In the present study of 16 anorectic inpatients a behavioural treatment programme, which had been applied in a former investigation at the same unit, was modified and yielded the following results: rapid increase in weight, good improvement of anorectic and depressive symptoms and a treatment duration of less than 3 months. Although the short-term outcome of the modified treatment programme is encouraging, the therapeutic difficulties encountered in this programme deserve special attention and its long-term effects on the course and prognosis of anorexia nervosa have to be established.

Abstract
Whereas in psychophysiological research, the specificity of the individual responses has been assumed to be an important trait variable influencing the investigated parameters in stress experiments or in psychopathological states, in psychoneuroendocrinology, the individual differences in the susceptibility of the investigated neuroendocrine axes have been widely neglected. The present study on the cortisol response of 12 healthy young men to 5 different stress tests is considered to be an initial orientation step into this field. All five stress tests (quiz, arithmetic tasks, stress film, cold pressor test, and physical exercise test) could be proven to be effective stimuli regarding the cortisol system. There was, however, a broad spectrum of cortisol responses among the 12 subjects, with a continuum between complete reactors and nonreactors. This did not correlate with the subjective judgment of stress at all. Although the data showed a tendency toward an augmented dispersion of the response frequencies in comparison with random variation, the limited sample size of subjects and stress tests did not allow a statistically significant proof of a stimulus-independent, individual response specificity. Further experimental clarification seems to be necessary to avoid misinterpretations of neuroendocrine data in psychiatric disorders due to neglect of this variable.

Abstract
To test the assumption that activation of the hypothalamic-pituitary-adrenocortical (HPA) axis is mediated by cholinergic neurons, the cortisol response to the administration of the muscarinic agonist RS 86 was investigated in 12 healthy volunteers. In addition, prolactin and growth hormone secretion patterns were assessed. No significant increase in plasma cortisol or growth hormone was observed after the administration of 1.5 and 3.0 mg RS 86, respectively. However, there was a slight increase in prolactin serum concentration after 3.0 mg RS 86. As RS 86, when used in the same dose range, causes a shortening of rapid eye movement (REM) latency and displays antimanic properties, it is unlikely that a reduced dosage of RS 86 in itself accounts for the lack of stimulation of the HPA axis. If one assumes that in humans the stimulation of the HPA axis is under cholinergic control, then the failure of RS 86 to increase cortisol might be attributable to the fact that different subtypes of muscarinic neurons, for which RS 86 is not a full agonist, are involved, or else nicotinic neurons are implicated in the activation of the HPA axis.

Abstract
A disturbed regulation of cortisol secretion is the principal pathology of Cushing's disease and is also the most widely reported neuroendocrine dysfunction in endogenous depression. Because additional clinical signs in both diseases indicated a hypothetical common pathway, we examined 17 patients suffering from Cushing's disease, following a protocol identical to that used in depressed patients (e.g., Hamilton Rating Scale for Depression, self-rating scales, and a clinical interview). Affective disorders, frequently observed in patients with Cushing's disease, were undetectable after surgical treatment (adrenalectomy or microadenomectomy of hypercortisolism). This was an unexpected result, since we found that recovered patients were still characterized by a disturbance of glucocorticoid feedback regulation, probably acting at the hypothalamic level. Our results, as well as numerous reports from others, failed to support the hypothesis that an impaired regulation of cortisol is directly linked to depressive illness.
