Self-esteem in a broad-spectrum approach for mental health promotion.

Self-evaluation is crucial to mental and social well-being. It influences aspirations, personal goals and interaction with others. This paper stresses the importance of self-esteem as a protective factor and a non-specific risk factor in physical and mental health. Evidence is presented illustrating that self-esteem can lead to better health and social behavior, and that poor self-esteem is associated with a broad range of mental disorders and social problems, both internalizing problems (e.g. depression, suicidal tendencies, eating disorders and anxiety) and externalizing problems (e.g. violence and substance abuse). We discuss the dynamics of self-esteem in these relations. It is argued that an understanding of the development of self-esteem, its outcomes, and its active protection and promotion are critical to the improvement of both mental and physical health. The consequences for theory development, program development and health education research are addressed. Focusing on self-esteem is considered a core element of mental health promotion and a fruitful basis for a broad-spectrum approach.     

Treatment of severe acute lung allograft rejection with OKT3 and temporary extracorporeal membrane oxygenation bridging.

OBJECTIVES: The use of OKT3 for treatment of advanced high-grade acute rejection episodes eventually can result in cytokine release and consecutive pulmonary edema. Temporary extracorporeal membrane oxygenation (ECMO) bridging can be used to overcome this crucial period before the beneficial effects of OKT3 can be observed. METHODS: We summarize our experience with three patients, who underwent lung transplantation and presented with severe acute rejection episodes. OKT3 had to be initiated due to insufficient response to standard rejection therapy with corticosteroids. Upon initiation of OKT3 treatment, a massive life-threatening deterioration of lung function in spite of heavily invasive respirator treatment was seen and temporary ECMO support was imperative to support graft function. Results of this treatment were retrospectively reviewed. RESULTS: In all cases femoro-femoral veno-arterial ECMO was used for support of the impaired graft and after a period of 4-5 days led to a massive improvement of graft function. In the further course two patients could be discharged from hospital and are still alive 30 and 36 months, respectively, after the described incident. One patient died 4 months later due to liver failure. CONCLUSIONS: We conclude that the use of ECMO support in patients experiencing significant side effects from OKT3 therapy is a useful and effective therapeutic tool to overcome the initial critical period until the lung has sufficiently recovered.     

Lessons to be learned from a complicated case of rhino-cerebral mucormycosis in a renal allograft recipient

Fungal infections still represent a serious complication after organ transplantation. Early diagnosis and aggressive treatment are crucial. Because of the many diagnostic problems involved, we present a case of mucormycosis--primarily affecting the paranasal sinuses with later intracranial extension--in a highly immunized recipient of a third renal transplant. Although fungal infection was suspected from various imaging techniques, only the detection of typical fungal hyphae in the infected tissue was diagnostic. Neither the blood tests and cerebrospinal fluid examinations performed nor cultures from maxillary sinus fluid were of any diagnostic help. Surgical debridement from a transnasal as well as an intracranial approach and systemic amphotericin B together with the discontinuation of immunosuppression after removal of the rejected graft were able to save the patient. This case stresses the importance of early diagnosis that can only be made from tissue biopsies and allows appropriate timely treatment.     

Increased sensitivity of virus-infected cells to inhibitors of protein synthesis does not correlate with changes in plasma membrane permeability

Semliki Forest virus-infected BHK cells or herpes simplex virus-infected Vero cells were incubated with the protein synthesis inhibitors hygromycin B and gougerotin. Infected cells take up no more [3H]hygromycin or [3H]gougerotin than do mock-infected cells, at a time p.i. at which either compound is more inhibitory to protein synthesis in infected, than in mock-infected cells. The concentrations of hygromycin and gougerotin required to inhibit protein synthesis in intact cells (irrespective of whether they are infected or not) are several orders of magnitude higher than those required in either permeabilized cells or in cell-free systems. Infected cells take up 86Rb+ at the same rate as mock-infected cells, their intracellular content of K+ is the same, and the activity of the Na+ pump is the same. It is concluded that the increased efficacy of hygromycin and gougerotin in virus-infected cells is a consequence of altered intracellular compartmentation and that increases in permeability of the plasma membrane, if any, are so small as to be undetectable by direct methods.     

Maternal serum caffeine metabolites and small-for-gestational age birth.

To determine whether the third-trimester maternal serum concentration of paraxanthine, caffeine's primary metabolite, is associated with delivery of a small-for-gestational age infant (birth weight less than the 10th percentile for gestational age, gender, and ethnicity) and whether this association differs by smoking, the authors studied 2,515 women who participated in the Collaborative Perinatal Project from 1959 to 1966. The women provided a third-trimester serum sample and had been controls for a nested case-control study of spontaneous abortion. The mean serum paraxanthine concentration was greater in women who gave birth to small-for-gestational age infants (754 ng/ml) than to appropriately grown infants (653 ng/ml, p = 0.02). However, the linear trend for increasing serum paraxanthine concentration to be associated with increasing risk of small-for-gestational age birth was confined to women who also smoked (p = 0.03). There was no association between paraxanthine and fetal growth in nonsmokers (p = 0.48). Adjustment for maternal age, pre-pregnant weight, education, parity, ethnicity, and the number of cigarettes smoked per day did not alter the results substantially, although the p value for trend among smokers increased to 0.07. The authors conclude that maternal third-trimester serum paraxanthine concentration, which reflects caffeine consumption, was associated with a higher risk of reduced fetal growth, particularly among women who smoked.     

Plasma lyso-phosphatidylcholine concentration is decreased in cancer patients with weight loss and activated inflammatory status

Background  

It has been observed that ras-transformed cell lines in culture have a higher phosphatidylcholine (PC) biosynthesis rate as well as higher PC-degradation rate (increased PC-turnover) than normal cells. In correspondence to these findings, the concentrations of the PC-degradation product lyso-phosphatidylcholine (LPC) in cancer patients were found to be decreased. Our objective was the systematic investigation of the relationship between LPC and inflammatory and nutritional parameters in cancer patients. Therefore, plasma LPC concentrations were assessed in 59 cancer patients and related to nutritional and inflammatory parameters. To determine LPC in blood plasma we developed and validated a HPTLC method.     

Self management of oral anticoagulation with the IN Ratio system: impact of a structured teaching program on patient's knowledge of medical background and procedures.

BACKGROUND: Self management of oral anticoagulation (OAC) decreases complication rates and improves quality of life. Manual and cognitive abilities of patients and patient training in a structured format are a precondition for this concept. Up to now, there is no evidence about knowledge increase from teaching programs. METHODS: Seventy-six patients (mean age, 57.4 years, 71% male) who started long-term OAC were included in the prospective multi-center study at three teaching centers representing different populations of anticoagulation patients: a department of cardiovascular surgery, an inpatient rehabilitation center and an anticoagulation clinic. The patients were trained in a structured education program for two days. For the evaluation, the patients performed standardized tests including 16 questions prior to start (T0), after each training unit (T1/T2) and 6 weeks later (T3). The primary endpoint was the percentage of > or =75% of patients who could answer > or =50% of questions correctly at T3. Secondary endpoints were the overall and item-specific percentages of correct answers at the end of each training unit (T1, T2) and at T3. In addition, the teaching program was rated by the patients on a six-point rating scale. RESULTS: Seventy-four out of 76 patients gave at least 50% correct answers at T3 (97.4%; 95% confidence interval, 90.8-99.7%). The average rates of correct answers developed from 40% (T0), 86% (T1), 94% (T2) to 96% (T3). The greatest increase of knowledge was observed with blood components, interpretation of International Normalized Ratio (INR) value, and the interaction of anticoagulation with other variables (e.g. drugs or infection). Patients rated the teaching program between 1 (best rating) and 2 at all time points. At T3, the patients reported less fear of complications and less limitations in their daily life than in earlier evaluations. CONCLUSION: The structured training program INRatio appears to be an appropriate instrument for instruction of INR self management. In comparison with baseline knowledge, the percentage of correctly answered questions was twice as high directly after the end of training and remained at a high level of >90% for at least 6 weeks.
