Attachment styles and healthcare utilization: exploring the role of the patient-doctor relationship.

BACKGROUND: With the purpose of improving healthcare, past research has examined the link between healthcare utilization and attachment. It is suggested that an individual's attachment style influences both the quality of their patient-physician relationship and healthcare utilization patterns. Nevertheless, most studies concentrate on the individual aspect, overlooking the dyadic dimension; specifically, the investigation of how insecure attachment relates to health behavior within patient-physician relationships. This gap leaves the role of the patient-doctor relationship in this process unclear. Therefore, to elucidate this complex interplay, we hypothesized that the correlation between attachment and healthcare utilization is mediated by the quality of the patient-physician-relationship. METHOD: Participant selection was based on electoral districts, a random-route procedure, and the Kish selection grid. The participants were visited by a trained interviewer who collected psychometric and sociodemographic information. Participants answered the Experiences in Close Relationships-Revised questionnaire (ECR-RD8) and the Patient-Doctor Relationship Questionnaire (PDRQ-9). Additionally, participants were asked about their healthcare utilization. The final sample consisted of N = 2.275 participants. RESULTS: In average the participants reported consulting their primary health care practitioner M(SD) = 4.44 (4.76) times in the past 12 months. Generally, the participants rated the quality of the relationship with their primary health care practitioner close to "totally appropriate" (M = 4.12 ± .69). The degree of insecure attachment manifested towards the lower extremity of the scale. The total effect of the mediation analyses was significant. Regardless, the indirect effect indicated a trend result with minimal effect sizes. CONCLUSION: The findings of the current study bridged the gap between attachment styles and healthcare utilization. Nonetheless, our results suggested insufficient support for the mediating role of the primary care physician in the relationship between attachment style and healthcare utilization. Considering the characteristics of the sample, this outcome may not apply in a clinical context. However, further research is needed to shed light in the revealed trends and indicate implications.

[The 2-Scale Model of the National Eye Institute Visual Function Questionnaire (NEI-VFQ) to Assess Vision-Related Quality of Life]. / Das 2-Skalen-Modell des National Eye Institute Visual Function Questionnaire (NEI-VFQ) zur Erfassung der sehbezogenen Lebensqualität.

Aim This study addresses the examination of the factorial validity of the National Eye Institute Visual Function Questionnaire 39 (NEI-VFQ 39) and the neuro-ophthalmological supplement in a German sample. Method Eighty-one patients with visual field defects affecting at least one eye answered the NEI-VFQ 39 and the supplement. Theoretical factor structures reported in the manuals were examined in confirmatory factor analysis. Because of a misfit, items retained after item analysis were subjected to exploratory factor analysis. Results The originally postulated factor structures could not be replicated. Many items revealed floor effects. The 21 remaining items could be assigned to two factors - "visual functioning" and "socio-emotional impairment". Conclusion The weakness of the theoretical factors can be avoided by using the 2-scale model.

Favorable outcome in children and adolescents with a high proportion of advanced phase disease using single/multiple autologous or matched/mismatched allogeneic stem cell transplantations.

We determined the indication, outcome, and risk factors of single and multiple hematopoietic stem cell transplantation(s) (HSCT) in children and adolescents mostly with advanced disease. Forty-one out of 483 patients (8.5 %; median age 9 years) diagnosed at the University of Leipzig with hematological and oncological diseases required HSCT from 1999 to 2011. Patients had overall survival (OS) of 63 ± 10 and 63 ± 16 %, event-free survival (EFS) of 57 ± 10 and 42 ± 16 %, relapse incidence (RI) of 39 ± 10 and 44 ± 18 % and nonrelapse mortality (NRM) of 4 ± 4 and 13 ± 9 % at 10 years after one or more allogeneic and autologous HSCT, respectively. One patient in CR1 and five with advanced disease received two HSCT. Four of the six patients maintained/achieved CR for a median of 13 months. Three died of progression and one of NRM. Two patients had a third HSCT and one survived in CR +231 days after HSCT. Risk factors for OS and EFS were disease stage at HSCT and EBMT risk score. Center (pediatric or JACIE accredited pediatric/adult) was not a determinant for survival. Pediatric single and multiple HSCT are important curative approaches for high-risk malignant diseases with low NRM. Efforts to reduce high RI remain the major aim.

[Imaging Blood Flow and Pulsation of Retinal Vessels with Full-Field Swept-Source OCT]. / Darstellung von Blutfluss und Pulsation in retinalen Gefäßen mit Full-Field-Swept-Source-OCT.

Optical coherence tomography (OCT) uses interference to image the retina with high axial resolution. In the last 25 years, new technologies have permitted a steady increase in imaging speed, which made it possible to enlarge the imaged field and to avoid motion artefacts. The speed and precision of retinal imaging is now limited by photodamage of the retina caused by the focused OCT beam and by the speed of the scanning mechanics. Full-field swept-source (FF-SS)-OCT decreases irradiance on the retina and dispenses moving parts by using a camera to acquire the full volume of the retina in parallel. Here we show that FF-SS-OCT is rapid and precise enough to image pulsation in the retina induced by the heart beat. Series of OCT volumes 1.8 × 0.7 mm wide and 1.8 mm deep were recorded in young volunteers over a few cycles of the heart beat. Morphology of the retinal vessels, blood flow and tissue motion as caused by vessel pulsation were calculated from the OCT data. FF-SS-OCT was able to visualise the main structures of the neuronal retina, including vessels and small capillaries and without any motion artefacts. Information on three different dynamic processes was obtained from only one recorded series of OCT volumes: pulsation of blood flow and blood pressure in retinal vessels as well as pulsation of the choroid. Delays between arterial and venous pulse and delay between pulsation in retinal and choroidal vessels were calculated. With a time resolution of 0.5 ms, FF-SS-OCT is able to visualise previously unmeasurably fast changes in the retina, including the propagation of pulse waves.

Improved detection of bacterial central nervous system infections by use of a broad-range PCR assay.

A universal PCR assay for bacteria and fungi detected meningitis pathogens in 65% of 20 cerebrospinal fluid (CSF) samples from patients with suspected central nervous system (CNS) infections compared to a 35% detection rate by culture and/or microscopy methods. Thus, the PCR assay can improve the diagnosis rate of infective meningitis when standard methods provide a negative result.

Overview of tight fit and infection prevention benefits of respirators (filtering face pieces).

Regulations for measures to protect against SARS-CoV-2 transmission vary widely around the world, with very strict regulations in Germany where respirators (filtering face piece FFP2 or comparable) are often mandatory. The efficiency of respirators, however, depends essentially on the tight facial fit avoiding the bypass of contaminated air via gaps between mask and wearer's face. The facial fit can be verified in a fit test. The aim of this review was to describe the quantitative fit test results depending on the respirator designs. A literature search revealed 29 suitable studies. Of all respirators with circumferential head straps, three-panel folded dome-shaped respirators showed the best fit (80.8% of 4625 fit tests passed), followed by rigid-dome-shaped respirators (72.4% of 8234 fit tests passed), duckbill-shaped respirators (31.6% of 2120 fit tests passed), and coffee-filter-shaped respirators (30.9% of 3392 fit tests passed). Respirators with ear loops showed very poor tight fit (3.6% of 222 fit tests passed). In four randomized control trials, single-use respirators were not shown to be superior to surgical masks for the prevention of laboratory-confirmed viral respiratory infections, even when adjusted with a fit test. Therefore, we consider the mandatory use of respirators to be disproportionate and not supported by evidence. Further evidence should be generated, in which scenarios respirators might provide an effective benefit as part of occupational health and safety. For situations with confirmed benefits, only high-quality disposable respirators with head straps or respiratory protective equipment of higher protective levels should be used.

Superiority of manual disinfection using pre-soaked wipes over automatic UV-C radiation without prior cleaning.

BACKGROUND: The efficacy of ultraviolet C (UV-C) radiation against a broad spectrum of micro-organisms has been demonstrated in several studies, but differences in the specific doses and the extent of microbial reduction were found. Furthermore, the conditions of laboratory tests differ greatly from reality, such that efficacy achieved in tests may not necessarily be assumed in reality. Consequently, it is important to investigate the effectiveness of UV-C in representative field trials. The aim was therefore to develop and establish a field test to evaluate automatic UV-C in comparison to manual disinfection. METHODS: Before and after disinfection, samples were repeatedly collected from naturally highly contaminated surfaces using the swab technique to obtain representative data sets for disinfected and non-disinfected surfaces. Subsequently, the log reduction values (LRV) and the disinfection success were evaluated for UV-C radiation and full compliant manual disinfection using alcohol-based wipes. RESULTS: Surfaces that are naturally contaminated with bacteria on a regular and nearly uniform basis have been identified as particularly suitable for field testing. Mean contamination was reduced from 23.3 to 1.98 cfu/cm2 (LRV 0.9) and 29.7 to 0.26 cfu/cm2 (LRV 1.2) for UV-C and manual disinfection, respectively. UV-C disinfection achieved 75.5% successful disinfected surfaces, whereas manual disinfection showed 98.1%. CONCLUSIONS: Full compliant manual disinfection showed slightly higher LRVs and disinfection success than automatic UV-C disinfection. Successful, operator-independent UV-C disinfection still has the potential to improve disinfection performance in addition to manual disinfection.

Tolerance of clinical vancomycin-resistant Enterococcus faecium isolates against UV-C light from a mobile source.

BACKGROUND: Admission to a room previously occupied by patients carrying environmentally robust pathogens implies an increased risk of acquiring those pathogens. Therefore, 'No-touch' automated room disinfection systems, including devices based on UV-C irradiation, are discussed to improve terminal cleaning. It is still unclear if clinical isolates of relevant pathogens behave differently under UV-C irradiation compared to laboratory strains used in the approval process of disinfection procedures. In this study we analysed the susceptibility of well characterized clonally divergent vancomycin-resistant enterococci (VRE) strains, including a linezolid-resistant isolate, against UV-C radiation. METHODS: Susceptibility against UV-C of ten clonally divergent clinical isolates of VRE was determined in comparison to the commonly used test organism Enterococcus hirae ATCC 10541. Ceramic tiles contaminated with 105 to 106 colony forming units/25 cm² of the different enterococci were positioned at a distance of 1.0 and 1.5 m and irradiated for 20 s, resulting in a UV-C dose of 50 and 22 mJ/cm², respectively. Reduction factors were calculated after quantitative culture of the bacteria recovered from treated and untreated surfaces. RESULTS: Susceptibility to UV-C varied considerably among the strains studied, with the mean value of the most robust strain being up to a power of ten lower compared to the most sensitive strain at both UV-C doses. The two most tolerant strains belonged to MLST sequence types ST80 and ST1283. The susceptibility of the laboratory strain E. hirae ATCC 10541 ranged between the most sensitive and most tolerant isolates for both irradiation doses. However, for UV-C dose of 22 mJ/cm², the reduction of the most tolerant isolate of ST1283 was statistically significantly lower compared to E. hirae ATCC 10541. The most susceptible strains belonged to the MLST sequence types ST117 and ST203. CONCLUSIONS: These results indicate that UV-C doses reported in the literature are sufficient for the reduction of commonly used reference strains of enterococci but could be insufficient for the reduction of tolerant patient VRE-isolates in a hospital setting. Therefore, for future studies, the most tolerant clinical isolates should be used to validate automated UV-C devices or longer exposure times should be expected to ensure efficacy in the real world.

[Patient safety in differentiated (in-hospital) activation of the resuscitation room for severely injured patients]. / Patientensicherheit bei differenzierter (innerklinischer) Schockraumaktivierung für Schwerverletzte.

BACKGROUND AND OBJECTIVE: Providing trauma services demands high personnel resources and structural costs. The goal of this study was to show if the assignment of trauma patients to a defined A or B resuscitation room treatment as a modified management concept is safe and feasible. MATERIAL AND METHODS: Between May 2020 and January 2021, all resuscitation room trauma patients were included in this single center prospective observational study. All patients admitted to the resuscitation room underwent a classification according to the German S3 guidelines grade of recommendation GoR A and GoR B in polytrauma and the status of the ABCDE sequence to an A and B resuscitation room. The classification was performed by the senior consultant on call via telephone after consultation and discussion of clinical findings. RESULTS: All 135 resuscitation room patients were included in the study of whom 42 trauma patients were assigned to the A resuscitation room (A-SR) and 93 were assigned to the B resuscitation room (B-SR). The comparison of the two groups showed that patients in the A­SR group are more likely to be accompanied by a prehospital emergency physician (80.5%) than patients in the B­SR group (55.5%). Patients in the B­SR group showed a significantly higher Glasgow coma scale (GCS). Using the eFAST emergency ultrasound protocol, 2.4% of the A­SR and 4.3% of the B­SR patients had trauma-associated pathologies, 26% of the A­SR and only 3.2% of the B­SR patients had to be admitted to the ICU, 21.4% of the A­SR and 1% of the B­SR patients died within 30 days after trauma. The injury severity scores (ISS) of the A­SR patients were significantly higher than in the B­SR group (ISS 28.3 vs. 6.8). CONCLUSION: The study confirmed that the assignment by the emergency department consultant according to the German S3 guideline in combination with the ABCDE sequence into resuscitation room A or B treatment is feasible, does not compromise the quality of care and is efficient in the use of the personnel resources.

[The short version of the Brief Symptom Inventory (BSI -18): preliminary psychometric properties of the German translation]. / Die Kurzform des Brief Symptom Inventory (BSI -18): erste Befunde zu den psychometrischen Kennwerten der deutschen Version.

The short version of the Brief Symptom Inventory (BSI-18) is an easily applicable, reliable and valid self-report measure in wide international use. It assesses the syndroms of somatisation, depression and anxiety by means of 6 items each. For the psychometric evaluation of the German translation, undergraduate students, non-clinical subjects and psychosomatic outpatients were administered the BSI-18. Across these populations, all scales showed satisfactory to good internal consistencies (Cronbachs alpha ranged between 0.63 and 0.93). The item-total correlation as item discrimination index was sufficiently high, patricularly in the patient sample (rit ≥ 0.40). The correlations of the BSI-18 with measures of similar dimensions were moderate to high indicating a good convergent validity. Criterion-related validity was established in so far that patients scored significantly higher in all BSI-18 scales than did the non-clinical samples. With some exceptions, the German translation of the BSI-18 has similarly good psychometric qualities as the American original.

An automated room disinfection system using ozone is highly active against surrogates for SARS-CoV-2.

BACKGROUND: The presence of coronaviruses on surfaces in the patient environment is a potential source of indirect transmission. Manual cleaning and disinfection measures do not always achieve sufficient removal of surface contamination. This increases the importance of automated solutions in the context of final disinfection of rooms in the hospital setting. Ozone is a highly effective disinfectant which, combined with high humidity, is an effective agent against respiratory viruses. Current devices allow continuous nebulization for high room humidity as well as ozone production without any consumables. AIM: In the following study, the effectiveness of a fully automatic room decontamination system based on ozone was tested against bacteriophage Φ6 (phi 6) and bovine coronavirus L9, as surrogate viruses for the pandemic coronavirus SARS-CoV-2. METHODS: For this purpose, various surfaces (ceramic tile, stainless steel surface and furniture board) were soiled with the surrogate viruses and placed at two different levels in a gas-tight test room. After using the automatic decontamination device according to the manufacturer's instructions, the surrogate viruses were recovered from the surfaces and examined by quantitative cultures. Then, reduction factors were calculated. FINDINGS: The ozone-based room decontamination device achieved virucidal efficacy (reduction factor >4 log10) against both surrogate organisms regardless of the different surfaces and positions confirming a high activity under the used conditions. CONCLUSION: Ozone is highly active against SARS-CoV-2 surrogate organisms. Further investigations are necessary for a safe application and efficacy in practice as well as integration into routine processes.

[A comparison of multimodal programmes of patient education in the rehabilitation of chronic low back pain]. / Multimodale Interventionsprogramme in der Rehabilitation von Patienten mit chronischen Rückenschmerzen--Ein Vergleich.

There is growing evidence for the effectiveness of multimodal intervention concepts for chronic low back pain in the international literature, and accordingly several German rehabilitation programmes for the treatment of chronic low back pain patients have been developed. Focus of this paper is to describe and compare frequently used German multimodal intervention programmes for in- and outpatient rehabilitation of patients with chronic low back pain. Programmes were chosen by searching the most relevant online resources as well as the online pages of Deutsche Rentenversicherung and Zentrum Patientenschulung during September 2008. Keywords guiding the search were: Patientenschulung, Rückenschmerzen, Manual, psychologische multimodale Interventionskonzepte, Rehabilitationsprogramm, psychology, intervention, low back pain, manual and therapy. By this means, six manually supported multimodal rehabilitation programmes for the in- and outpatient therapy of patients with chronic back pain could be identified: Göttinger Rücken-Intensiv-Programm (GRIP), the psychological programme for chronic head- and low back pain, the Münchner Rücken-Intensiv-Programm (MRIP), Back to Balance, Arbeiten und Leben--Back to Balance (ALEBABA) und Rückenfit: Lebenslust statt Krankheitsfrust. These programmes are depicted and compared with regard to their potentials and limitations in supporting the rehabilitation process of patients with chronic low back pain. While comparing the programmes, a number of similarities between them can be detected, as well as pronounced differences, e. g., regarding settings and complexity. In most programmes, lack of appropriate evaluation studies and lack of aftercare turn out to be critical aspects.

[Psychological factors related to gastric banding. Results of a follow-up study]. / Psychische Faktoren bei Magenbandimplantation. Ergebnisse einer Follow-up-Untersuchung.

BACKGROUND: Obesity is a widespread illness in Western industrialized countries, causing a high financial burden for the health systems. Several studies could demonstrate the positive effects of bariatric surgery on psychological and psychosocial parameters. PATIENTS AND METHODS: Twenty patients with morbid obesity (BMI > or =40 kg/m(2)) answered two questionnaires, the SCL-90-R, assessing psychological distress, and the IIP-D, measuring interpersonal problems, before and 6 months after gastric banding. Six months after surgery an additional questionnaire measuring subjective feelings was administered, too. RESULTS: Seventy-five percent of the patients were dissatisfied with therapy and outcome. They reported a lack of psychological support as well as new surgery-related physical and psychological symptoms. CONCLUSION: This study pointed out the necessity for psychotherapeutic help after surgery to manage already existing or new psychological needs due to gastric banding.

[Impairments of vision- and health-related quality of life in stroke patients with homonymous visual field defects depend on severity of visual function loss]. / Beeinträchtigung der seh- und gesundheitsbezogenen Lebensqualität bei Schlaganfallpatienten mit homonymen Gesichtsfelddefekten in Abhängigkeit von der Schwere des visuellen Funktionsverlustes.

BACKGROUND AND PURPOSE: Little is known about whether and to what extent health- and vision-related quality of life in stroke patients with visual field defects is influenced by the severity of visual function loss and which quality of life is achieved compared to healthy control persons. PATIENTS/MATERIALS AND METHODS: Results of the National Eye Institute-Visual Functioning Questionnaire (NEI-VFQ) and the Medical Outcome Study Short-Form 36 Health Survey (SF-36) of 177 first stroke patients with visual field defects were compared with scores of age- and sex-matched healthy reference persons. The influence of visual field loss, perimetric data, reduced visual acuity and demographic variables on NEI-VFQ and SF-36 scores were estimated by analyses of variance. RESULTS: First stroke patients showed worse results in 11/12 NEI-VFQ and in 6/8 SF-36 subscales when compared to healthy controls. The factor "intact central visual field" influenced 9/12 NEI-VFQ subscales (F-range 3.16 - 14.11; all p < 0.05), but only one SF-36 scale (F = 3.15; p < 0.05). Patients with larger intact visual fields, shorter reaction times in the visual field test and better visual acuity reached higher NEI-VFQ and SF-36 scores. Male patients reported worse scores for SF-36 subscale General Health Perceptions than female patients (F = 8.61; p = 0.004), but no differences in vision-related quality of life due to the factor gender could be detected. CONCLUSIONS: Patients with visual field defects showed considerable reductions in vision- and health-related quality of life compared to healthy control persons. These were mainly influenced by variables of visual functioning such as size of intact visual field, reaction times or visual acuity. The size of the intact central visual field influenced vision-related quality of life rather than health-related quality of life.

Investigation of the anti-inflammatory potential of Aloe vera gel (97.5%) in the ultraviolet erythema test.

BACKGROUND: Aloe vera is a natural product that is frequently used in soothing skin care products such as aftersun lotions. In the present study we aimed to explore the anti-inflammatory potential of a highly concentrated A. vera gel in the UV erythema test in vivo. METHODS: 40 volunteers with skin types II and III were included in the randomized, double-blind, placebo-controlled, phase III monocenter study. Test areas on the back were irradiated with the 1.5-fold minimal erythema dose of UVB. Subsequently, the test areas were treated occlusively on 2 subsequent days with A. vera gel (97.5%), the positive controls (0.25% prednicarbate, 1% hydrocortisone in placebo gel and 1% hydrocortisone cream) and a placebo gel. Erythema values were determined photometrically after 24 and 48 h. RESULTS: A. vera gel (97.5%) significantly reduced UV-induced erythema after 48 h, being superior to 1% hydrocortisone in placebo gel. In contrast, 1% hydrocortisone in cream was more efficient than A. vera gel. CONCLUSIONS: In this study after 48 h the A. vera gel (97.5%) displayed some anti-inflammatory effects superior to those of 1% hydrocortisone in placebo gel. The A. vera gel tested here might be useful in the topical treatment of inflammatory skin conditions such as UV-induced erythema.

[Quality of life - methodology and clinical practice aspects with a focus on ocular medicine]. / Lebensqualität - methodologische und klinisch-praktische Aspekte mit einem Fokus auf die Augenheilkunde.

Due to the demographic development in western industrialised countries, the proportion of visually impaired persons is likely to increase in the future. Currently there is a shift in scientific recognition from relative neglect of psychopathological distress in the visually impaired to better notice of disease-related subjective impairments that are detectable with specific questionnaire measures. Visual acuity primarily determines the subjective rating of visual functioning independent from the eye disease. Ophthalmic patients who show only mild symptoms from a medical point of view normally suffer considerably diminished vision-related quality of life with respect to physical, functional, mental, and social aspects. Treatment effects have been shown using vision-related quality-of-life measures for different ophthalmic diseases, particularly cataract surgery. Assessment of vision-related quality of life provides a meaningful complement to objective data.

Expression and functional characterization of gfpmut3.1 and its unstable variants in Staphylococcus epidermidis.

Reporter gene systems are an invaluable tool for investigation of gene transcription activity in eukaryotes and prokaryotes. In order to analyze the temporal and spatial resolution of gene expression patterns in situ and for quantitatively investigating gene expression, the green fluorescent protein (GFP) appears to be especially useful. GFP has been broadly used in various bacterial species, however, there is only limited knowledge about key biological properties in S. epidermidis. Here, the crucial influence of different ribosomal binding sites (RBS) on gfpmut3.1 translation initiation in S. epidermidis 1457 is demonstrated. Only by using the RBS of the delta-hemolysin promoter, after 24 hours a strong fluorescence signal was obtained. The half-life of GFPmut3.1 in S. epidermidis 1457 was significantly shorter than in E. coli (7 h vs. 24 h). GFPmut3.1 derivatives with shorter half-lives (GFP(AAV) and GFP(ASV)) did not reach sufficient quantitative protein levels, and the resulting low fluorescence limits their use as reporter genes in S. epidermidis. This work provides fundamental insights into gfpmut3.1 expression in S. epidermidis and describes the crucial determinants of its biological behavior in this species. In general, this study underlines the need to accurately characterize key biological properties of this transcription marker in gram-positive hosts.

Tyramine in the assessment of regional adrenergic function.

Regional adrenergic function is difficult to assess in humans. Tyramine given through a microdialysis probe may be a useful tool in this regard. However, tyramine data is hard to interpret given the drug's complex mode of action. We characterized the response to tyramine, isoproterenol, and dopamine in adipose tissue with microdialysis probes in normal subjects. We measured glycerol concentrations to follow changes in lipolysis and monitored tissue perfusion with ethanol dilution. During perfusion with tyramine, dialysate glycerol concentration increased dose-dependently from 83+/-8 microM at baseline to 181+/-18 microM at 3.5 mM tyramine (p<0.001) followed by a fall down to 121+/-9 microM at 35 mM tyramine (p<0.001). Propranolol almost completely blocked this response. A similar lipolytic response was not observed in isolated human adipocytes. Dopamine <35 microM did not replicate the tyramine-induced lipolysis; however, dopamine >35 microM potently inhibited lipolysis. We conclude that tyramine-induced lipolysis is explained by a pre-synaptic mechanism. Tyramine applied through a microdialysis probe in concentrations up to 3.5 mM can be used to assess pre- and post-synaptic mechanisms regulating lipid mobilization.

Switching from cyclosporine to tacrolimus leads to improved disease-specific quality of life in patients after kidney transplantation.

BACKGROUND: Advances in transplantation medicine are linked to improved efficacy of immunosuppressive agents. At the same time, these agents endanger medical success by side effects that may impair survival and quality of life (QOL). This study examined whether conversion to tacrolimus-based immunosuppression due to cyclosporine-related side effects improved. QOL in patients after kidney transplantation. METHODS: In total 64 patients (29 men) with an average age of 51 years (SD+/-12) who had received a kidney allograft an average of 5.6 years (SD+/-4) before conversion participated. The reasons for conversion were cardiovascular/metabolic (n=26) or periodontal/dermatological side effects (n=38) of cyclosporine therapy. QOL was assessed before conversion and in average 7 months thereafter by a global (SF-36) and a disease-specific instrument (ESRD-SCL). RESULTS: Disease-specific QOL (ESRD-SCL, global index) improved significantly (P<.001, explanation of variance [EV]=16.6%) after conversion from cyclosporine to tacrolimus. In detail, cardiac and renal dysfunction (P<.01, EV=12.9%) as well as increased growth of gum and hair (P<.0001, EV=53.2%) were significantly reduced at end of the study. However, global QOL (SF-36) remained unchanged. CONCLUSION: Regardless of the indication (cardiovascular or cosmetic), switching to tacrolimus due to cyclosporine-related side effects improved disease-specific QOL within the short term.

Disease-specific quality of life in Turkish patients after successful kidney transplantation.

To investigate disease-specific quality of life (QOL) in Turkish patients after successful kidney transplantation, the End-Stage Renal Disease Symptom Checklist Transplantation Module (ESRD-SCL-TM), a multidimensional questionnaire measuring disease-specific QOL, was translated and administered to a sample of successfully transplanted patients. Intercultural differences between Turkish and German patients as well as the influence of demographic (age, gender) and clinical (duration of graft function, living versus cadaver transplantation) data in the Turkish patients were evaluated by multivariate analyses of variance, and correlative techniques. The 152 investigated Turkish patients, including 106 (69.7%) men and 46 (30.3%) women, had a mean age of 34.8 years (SD = 10.8, range, 14 to 67 years). Time since successful kidney transplantation varied between 1 and 297 months (mean = 19.2 months; SD = 36.9). One hundred twelve patients (73.7%) received a kidney from a living donor, and 40 (26.3%) from a cadaver. The Turkish patients suffered statistically significantly more from disease-specific distress than the German patients (19% explanation of variance). They reported higher distress regarding four of six subscales. Turkish women suffered statistically significantly more from "Limited Physical Capacity," and "Side-effects of Corticosteroids" (10% explanation of variance) than men. The demonstrated higher disease-specific distress in successfully transplanted Turkish patients compared to the German samples may be the result of intercultural differences in reporting psychological and disease-specific distress. On the other hand, the higher distress of women compared to men is well known. Both results pointed out the necessity of psychological support.
