Palliative care outpatients in a German comprehensive cancer center-identifying indicators for early and late referral.

PURPOSE: Despite that early integration of palliative care is recommended in advanced cancer patients, referrals to outpatient specialised palliative care (SPC) frequently occur late. Well-defined referral criteria are still missing. We analysed indicators associated with early (ER) and late referral (LR) to SPC of an high volume outpatient unit of a comprehensive cancer center. METHODS: Characteristics, laboratory parameters and symptom burden of 281 patients at first SPC referral were analysed. Timing of referral was categorized as early, intermediate and late (> 12, 3-12 and < 3 months before death). Ordinal logistic regression analysis was used to identify factors related to referral timing. Kruskal-Wallis test was used to determine symptom severity and laboratory parameter in each referral category. RESULTS: LRs (50.7%) had worse scores of weakness, loss of appetite, drowsiness, assistance of daily living (all p < 0.001) and organisation of care (p < 0.01) in contrast to ERs. The mean symptom sum score was significantly higher in LRs than ERs (13.03 vs. 16.08; p < 0.01). Parameters indicative of poor prognosis, such as elevated LDH, CRP and neutrophil-to-lymphocyte ratio (NLR) (p < 0.01) as well as the presence of ascites (p < 0.05), were significantly higher (all p < 0.001) in LRs. In univariable analyses, psychological distress (p < 0.05) and female gender (p < 0.05) were independently associated with an ER. CONCLUSION: A symptom sum score and parameters of poor prognosis like NLR or LDH might be useful to integrate into palliative care screening tools.

[PARPACT: Paramedic Palliative Care Test : Validation of a questionnaire to assess palliative care knowledge and self-efficacy expectations of paramedics]. / PARPACT ­ Paramedic Palliative Care Test : Validierung eines Tests für palliatives Wissen und Selbstwirksamkeitserwartung bei Mitarbeiter*innen im Rettungswesen.

BACKGROUND: Given the large number of palliative patients cared for by the emergency services, education and training in palliative care topics are playing an increasingly important role. To support decision-making in an emergency setting a palliative or emergency card has been introduced in many cities. OBJECTIVES: To assess the success of educational interventions and the effect of the palliative or emergency card, a questionnaire was developed and validated to determine palliative knowledge and palliative self-efficacy expectations in the emergency services. MATERIALS AND METHODS: A Delphi process was applied for development and content validation. Factor analysis was used for construct validation. Criterion validity was assessed with the help of 22 nurses specially trained in palliative care. Reliability was determined using Cronbach's alpha as a measure of internal consistency. RESULTS: In all, 291 of 750 paramedics participated in the voluntary survey. After completion of the Delphi process, there was consensus that the important topics of pain, dyspnea, sedation, end-of-life care, euthanasia, and legal aspects were covered in the questionnaire. Factor analysis was in favor of a six-factor solution. Criterion validation revealed a significant difference in palliative knowledge between palliative care nurses (MRang 289.73) and paramedics (MRang 146.97, U = 281.000, r = 0.40, p < 0.001). Cronbach's alpha was 0.70 for the knowledge questions and 0.82 for the palliative care self-efficacy expectancy subscale. CONCLUSIONS: The Paramedic Palliative Care Test (PARPACT) is a validated measurement tool for testing educational interventions in paramedicine.

Changes in fatigue, barriers, and predictors towards physical activity in advanced cancer patients over a period of 12 months-a comparative study.

PURPOSE: Physical activity (PA) is recommended to improve advanced cancer patients' (ACP) physical functioning, fatigue, and quality of life. Yet, little is known about ACPs' attitude towards PA and its influence on fatigue and depressiveness over a longer period. This prospective, non-interventional cohort study examined ACPs' fatigue, depression, motivation, and barriers towards PA before and after 12 months of treatment among ACP METHODS: Outpatients with incurable cancer receiving treatment at a German Comprehensive Cancer Center reporting moderate/severe weakness/tiredness during self-assessment via MIDOS II were enrolled. Fatigue (FACT-F), depression (PHQ-8), cancer-related parameters, self-assessed PA behavior, motivation for and barriers against PA were evaluated (T0). Follow-up data was acquired after 12 months (T1) using the same questionnaire. RESULTS: At follow-up, fatigue (p=0.017) and depressiveness (p=0.015) had increased in clinical relevant extent. Physically active ACP did not show significant progress of FACT-F (p=0.836) or PHQ-8 (p=0.799). Patient-reported barriers towards PA remained stable. Logistic regression analyses identified motivation as a positive predictor for PA at both time points (T0, ß=2.152, p=0.017; T1, ß =2.264, p=0.009). Clinically relevant depression was a negative predictor for PA at T0 and T1 (T0, ß=-3.187, p=0.044; T1, ß=-3.521, p=0.041). CONCLUSION: Our findings emphasize the importance of psychological conditions in physical activity behavior of ACP. Since psychological conditions seem to worsen over time, early integration of treatment is necessary. By combining therapy approaches of cognitive behavioral therapy and exercise in interdisciplinary care programs, the two treatment options might reinforce each other and sustainably improve ACPs' fatigue, physical functioning, and QoL.

Fatigue, barriers to physical activity and predictors for motivation to exercise in advanced Cancer patients.

BACKGROUND: In order to counteract fatigue, physical activity (PA) is recommended for all stages of cancer. However, only few advanced cancer patients (ACP) are physically active. Quantitative data with high numbers of ACP reporting barriers to PA are missing. This study aimed to identify barriers to PA in ACP with tiredness/weakness and investigate their motivation towards it. METHODS: Outpatients with metastatic cancer receiving cancer care at a German Cancer Center reporting moderate/severe tiredness/weakness during self-assessment (MIDOS II) were enrolled. We assessed Fatigue-(FACF-F) and Depression (PHQ8) Scores, demographics, cancer-specific parameters, motivation for PA, physical, psychological and social barriers. RESULTS: 141 of 440 eligible patients (32.0%) with different diagnoses agreed to participate. Patients frequently reported "I feel weakened due to my tumor therapy" (n = 108; 76.6%), physical symptoms (tiredness, weakness, dyspnea, joint-problems, pain, nausea [n = 107; 75.9%]) and fatigue (n = 99; 70.2%) as barriers to PA. However, no significant group differences regarding these barriers were found between physically active and inactive patients. Social barriers were rarely chosen. Motivated patients were 5.6 times more likely to be physically active (p < 0.001), also motivation turned out to be the strongest predictor for a physically active behavior (ß = 1.044; p = 0.005). Motivated attitude towards PA was predicted by fatigue (ß = - 2.301; p = 0.008), clinically relevant depression (ß = - 1.390, p = 0.039), knowledge about PA and quality of life (QoL) (ß = 0.929; p = 0.002), PA before diagnosis (ß = 0.688; p = 0.005 and Interest in exercise program (ß = 0.635; p = 0.008). CONCLUSION: "I feel weakened due to my tumor therapy" is the most reported barrier to PA among both, physically and inactive patients. Motivation for PA is the strongest predictor of performing PA. Interest in PA, knowledge about PA/QoL and PA before diagnosis are main predictors of a motivated attitude. Absence/presence of social barriers did not associate with motivation, fatigue and depression proved to be a negative predictor. Programs including information, motivational counseling and individualized training should be offered for ACP to overcome barriers and reduce fatigue.

[The influence of the pathologist on the mental well-being of the patient]. / Der Einfluss des Pathologen auf das psychische Wohlbefinden des Patienten.

The label cancer in itself leads to complex psychological reactions in patients that are closely related to previous experiences and self-image. A cancer diagnosis can lead to increased distress and subsequent mental comorbidity such as depression or anxiety disorders. The responsibility of the pathologist, as the person who first uses the label cancer, is high. The pathologist must be conscious and focus not only on the accuracy of the anatomical pathology, but also on the potential influences the wording may have on the mental health of the patient. The word "carcinoma" should only be used in the case of tumors with the respective biological behavior. The example of non-invasive follicular thyroid neoplasm with papillary-like nuclear features shows that changing a label can lead to an improvement in distress and quality of life.

How do patients with anorexia nervosa "process" psychotherapy between sessions? A comparison of cognitive-behavioral and psychodynamic interventions.

OBJECTIVE: Patients' processing of psychotherapy between sessions ("inter-session process" (ISP)) has been repeatedly shown to be related to outcome. The aim of this study was to compare ISP characteristics of cognitive-behavioral vs. psychodynamic psychotherapy in the treatment of anorexia nervosa (AN) and their relation to outcome. METHODS: Data of 106 patients participating in a randomized-controlled trial who received either 40 sessions of enhanced cognitive-behavioral therapy (CBT-E) or focal psychodynamic therapy (FPT) were analyzed. The ISP was measured with the Inter-session Experience Questionnaire (IEQ). Three outcome classes were distinguished: full recovery, partial recovery, and still fulfilling all AN criteria. RESULTS: Patients receiving CBT-E reported more on "applying therapy" in the initial and the final treatment phase compared to FPT patients. In terms of process-outcome relations, higher levels of "recreating the therapeutic dialogue between sessions," "recreating the therapeutic dialogue with negative emotions" as well as "applying therapy with negative emotions" in the final phase of treatment predicted negative outcome in FPT, whereas overall higher levels of negative emotions predicted negative outcome in CBT-E. CONCLUSIONS: In outpatient treatment in AN, the processing of therapy as measured by the IEQ showed surprisingly few differences between CBT-E and FPT. However, different ISP patterns were predictive of outcome, pointing to different mechanisms of change.

Assessing the need for psychooncological support: screening instruments in combination with patients' subjective evaluation may define psychooncological pathways.

BACKGROUND: Cancer patients suffer from severe distress. About one third show mental comorbidities. Nevertheless, there is no common agreement on how to measure distress or identify patients in need for psychooncological services using screening questionnaires. PATIENTS AND METHODS: A sample of N = 206 patients with confirmed breast cancer, being inpatient for surgical treatment, filled in distress assessment instruments: Distress Thermometer, Hospital Anxiety and Depression Scale, Patient Health Questionnaire 2, Hornheider Screening Instrument and parts of the EORTC-QLQ-C30. Additionally, they were asked for their subjective need for psychooncological counselling. RESULTS: The correlation between the assessment instruments is low to medium. The number of patients above the cut-off criteria varies quite a lot according to the instrument (10% to 66%). Therefore, the congruence between the instruments' indications is quite low. Patients with and without subjective need do not differ in personal data but in distress scores. CONCLUSIONS: Recommended instruments for distress assessment in psychooncology measure different areas of distress. They do not sufficiently agree in indicating a patient's need for psychooncological treatment. Hence, one should neither compare results of studies using different assessment instruments nor implement a screening without reflecting the used instrument's characteristics compared to the others. The subjective need seems to provide additional information to the assessment. At present, the combination of an assessment instrument and patients' subjective need is seen as a best practice for identifying patients in need of psychooncological treatment.

The OUTREACH study: oncologists of German university hospitals in rotation on a palliative care unit-evaluation of attitude and competence in palliative care and hospice.

PURPOSE: The effect of the duration of an educational rotation presented at a palliative care unit on the palliative care knowledge gain and the increase of palliative care self-efficacy expectations are unclear. METHODS: This national prospective multicenter pre-post survey conducted at twelve German University Comprehensive Cancer Centers prospectively enrolled physicians who were assigned to training rotations in specialized palliative care units for three, six, or twelve months. Palliative care knowledge [in %] and palliative care self-efficacy expectations [max. 57 points] were evaluated before and after the rotation with a validated questionnaire. RESULTS: From March 2018 to October 2020, questionnaires of 43 physicians were analyzed. Physicians participated in a 3- (n = 3), 6- (n = 21), or 12-month (n = 19) palliative care rotation after a median of 8 (0-19) professional years. The training background of rotating physicians covered a diverse spectrum of specialties; most frequently represented were medical oncology (n = 15), and anesthesiology (n = 11). After the rotation, median palliative care knowledge increased from 81.1% to 86.5% (p < .001), and median palliative care self-efficacy expectations scores increased from 38 to 50 points (p < .001). The effect of the 12-month rotation was not significantly greater than that of the 6-month rotation. CONCLUSION: An educational rotation presented in a specialized palliative care unit for at least six months significantly improves palliative care knowledge and palliative care self-efficacy expectations of physicians from various medical backgrounds.

Measurement of flow velocity profiles in tank structures using the prototype device OCM Pro LR.

Generally, studies investigating the treatment efficiency of tank structures for storm water or waste water treatment observe pollutant flows in connection with conditions of hydraulic loading. Further investigations evaluate internal processes in tank structures using computational fluid dynamic (CFD) modelling or lab scale tests. As flow paths inside of tank structures have a considerable influence on the treatment efficiency, flow velocity profile (FVP) measurements can provide a possibility to calibrate CFD models and contribute to a better understanding of pollutant transport processes in these structures. This study focuses on tests carried out with the prototype FVP measurement device OCM Pro LR by NIVUS in a sedimentation tank with combined sewer overflow (CSO) situated in Petange, Luxembourg. The OCM Pro LR measurement system analyses the echo of ultrasonic signals of different flow depths to get a detailed FVP. A comparison of flow velocity measured by OCM Pro LR with a vane measurement showed good conformity. The FVPs measured by OCM Pro LR point out shortcut flows within the tank structure during CSO events, which could cause a reduction of the cleaning efficiency of the structure. The results prove the applicability of FVP measurements in large-scale structures.

[Psychotherapy and obesity: strategies, challenges and possibilities]. / Psychotherapie und Adipositas : Strategien, Herausforderungen und Chancen.

One fifth of the German population is obese with increasing prevalence. Psychotherapy plays an important role in weight loss programmes. Cognitive behaviour therapy, targeting lifestyle changes, including exercise and eating behaviour, is the evidence-based treatment of choice. Especially the lack of motivation or absence of weight loss, further weight gain or psychosocial burden makes psychotherapy essential. The treatment of a comorbid binge eating disorder should be initiated prior to focusing on weight loss. Remarkably difficult stages in the treatment of obesity are the initiation of changes as well as the maintenance of the achieved weight loss. Internet-based attempts will become increasingly important.

[The consequences of subcutaneous India ink injection to produce factitial disease. Bilateral mastectomy, lymph node dissection, irradiation, and continued suspicion of neoplasia]. / Folgen von subkutaner Tuscheinjektion bei artifizieller Störung. Mastektomie, Lymphknotenausräumung, Radiatio und fortdauernder Malignomverdacht.

A 68-year-old woman with insulin-dependent diabetes mellitus presented with blue nodules on the ventral aspect of the thorax. According to the past history, these lesions had developed repeatedly. She had already had bilateral mastectomies and lymph node dissection. The histologic diagnosis was always mastitis with plasma cells and no neoplasia. Yet another biopsy was taken; the subcutis was stained blue-black. Histology revealed exogenous black pigment and mastitis. With Raman spectroscopy the pigment was identified as carbon black, which is a component of India ink. These findings together with the unusual course of the disease suggested the diagnosis of an artificial disorder. The likely conclusion is that our patient, over years, used her own (insulin) syringe to inject India ink into her skin and subcutaneous tissue; the damaging effect and tissue reaction was probably caused by preservatives such as phenol.

Rev-mediated nuclear export of RNA is dominant over nuclear retention and is coupled to the Ran-GTPase cycle.

The human immunodeficiency virus type-1 Rev protein induces the nuclear export of intron-containing viral mRNAs that harbor its binding site, the Rev response element (RRE). A leucine-rich region of Rev, the activation domain, is essential for function and has been shown to be a nuclear export signal (NES). Although Rev exports viral RNAs that resemble cellular mRNAs, competition studies performed using microinjected Xenopus laevis oocytes have previously indicated that Rev utilizes a non-mRNA export pathway. Here, we show that Rev is able to induce the export of both spliceable and non-spliceable RRE-containing pre-mRNAs and that this activity is not dependent on the location of the RRE within the RNA. Importantly, even RNA molecules of different classes, such as U3 snoRNA and U6 snRNA, which are retained in the nucleus by non-pre-mRNA mechanisms, are exported to the cytoplasm in response to Rev. Consistent with the notion that Rev-mediated export of RRE-containing RNA is mechanistically distinct from the export of processed cellular mRNA, a chimeric Rev protein in which its NES is replaced by the NES of hnRNP A1 does not induce the export of a Rev-responsive mRNA. Finally, we demonstrate that Rev/RRE-activated RNA export is, like other nuclear export pathways, linked to the Ran-GTPase cycle.

Vasoactive intestinal polypeptide (VIP) induces calcium mobilization in the human neuroblastoma cell line SK-N-SH.

Release of catecholamines, a Ca2(+)-dependent process, is the most useful biochemical marker in the diagnosis of neuroblastoma. Unfortunately, its stimulus is still unknown. We found that vasoactive intestinal polypeptide (VIP), in addition to acetylcholine and muscarine (but not nicotine), causes elevation of the cytoplasmic Ca2(+)-concentration in the highly differentiated human neuroblastoma cell line SK-N-SH, with or without the presence of extracellular Ca2+. Additionally, VIP was detected in SK-N-SH cells (0.65 ng/10(6) cells). Based on these observations and the fact that neuroblastoma is not innervated in vivo, we hypothesize that in this tumor VIP is responsible for Ca2(+)-dependent release of catecholamines in an autocrine or paracrine fashion.

A pilot study on polychlorinated biphenyl levels in the bone marrow of healthy individuals and leukemia patients.

In this pilot study the concentrations of polychlorinated biphenyls (PCBs) was determined by capillary column gas chromatography in bone marrow from 29 adults. The highest concentration in all adult individuals was detected for PCB no. 180 (mean = 0.991) followed by two other highly chlorinated PCBs, no. 153 (mean = 0.918) and no. 138 (mean = 0.927). The less chlorinated PCBs, no. 101 (mean = 0.255), no. 52 (mean = 0.161), and no. 28 (mean = 0.324) contributed to a lesser extent. Additional samples from children (N = 19) were used to assess the dependence of PCB concentrations on patient age (Scheele et al. Eur J Pediatr 1992; 151:802-805). When comparing the data of adult leukemia and lymphoma patients with a reference group of healthy adult individuals, no significant increase in the leukemia patients was found.

A comparison of the concentrations of certain chlorinated hydrocarbons and polychlorinated biphenyls in bone marrow and fat tissue of children and their concentrations in breast milk.

Chlorinated hydrocarbon (CHC) and polychlorinated biphenyl (PCB) concentrations in the bone marrow of 57 children were compared with the concentrations in adipose tissue of 50 children and the concentrations in breast milk in the Federal Republic of Germany from 1984 to 1991. The concentrations of hexachlorobenzene (HCB), the dichlorodiphenyltrichloroethane (DDT)-metabolites, and polychlorinated biphenyl (PCB) congeners no. 138 and no. 153 were increased threefold, while the concentrations of several hexachloro-cyclohexane (HCH)-isomers and PCB congener no. 180 were only increased twofold. Because breast feeding is the primary source of CHC and PCB in toddlers and infants we also compared the concentrations in bone marrow of children with the concentrations in breast milk and found approximately fourfold higher concentrations for the most highly chlorinated PCB congener no. 180, but only threefold higher concentration for PCB 138 and 153 and the DDT-metabolites. The concentrations of beta-HCH and HCB were only slightly higher in bone marrow.

Chlorinated hydrocarbons in human bone marrow of healthy individuals and leukemia patients.

In this pilot study, concentrations of chlorinated hydrocarbons in bone marrow were determined by capillary-column gas chromatography. Bone marrow was obtained from a total of 29 healthy adults and from patients with leukemia or lymphoma. The chlorinated hydrocarbons in adults that occurred in the highest concentrations were dichlorodiphenyltrichloroethane and its derivatives (mean = 129 mg/g DNA). Hexachlorobenzene, the hexachlorohexane isomers, and dieldrin were also found, but in reduced concentrations (i.e., mean concentrations: 49.5 mg/g DNA, 14.9 mg/g DNA, and 5.9 mg/g DNA, respectively). Patients who had leukemia and lymphoma did not have significantly increased concentrations of chlorinated hydrocarbons.

Food-related impulsivity in obesity and binge eating disorder--a systematic review.

Impulsivity towards food has been recognized as a potential factor leading to increased food intake in obesity. Patients suffering from binge eating disorder (BED) form a specific subgroup of obese people that might be characterized by increased impulsivity. These assumptions, although, have yet to be verified. Therefore, this review evaluates evidence for food-related impulsivity in obese people with and without BED and examines possible differences between both populations. More precisely, evidence for the two components of impulsivity is analyzed separately: evidence for reward sensitivity, specifically, the urge for appetitive stimuli and evidence for rash-spontaneous behaviour such as acting disinhibited with no regard for the consequences. Our search resulted in 51 articles demonstrating generally increased food-related impulsivity. We found particular emphasis on increased reward sensitivity in obese people, which appeared to be more pronounced in people with BED. There was little and conflicting evidence, however, concerning increased rash-spontaneous behaviour in obese people without BED, but consistent evidence of an increase in obese people with BED. All in all, the evidence supports the view that BED represents a specific phenotype of obesity with increased food-related impulsivity. Taking these specific deficits into account can enhance the effectiveness of weight reduction programmes and psychotherapy.

Heart rate variability in the irritable bowel syndrome: a review of the literature.

BACKGROUND: Patients with irritable bowel syndrome (IBS) often present with disturbances of bowel habits (diarrhea, constipation) and abdominal pain/discomfort that are modulated by the autonomic nerve system (ANS). In this narrative review, we analyzed studies that measured ANS functioning in IBS by means of heart rate variability (HRV). METHODS: The PUBMED was searched with the keywords 'irritable bowel syndrome' AND ('heart rate variability' OR 'autonomic function'). We included only papers that used 'traditional' HRV indices and diagnosed IBS based on Manning or Rome criteria. Studies were sub-grouped according to methodological features of HRV analysis (24-h monitoring, short-term laboratory records, records during sleep). KEY RESULTS: Most studies reported no difference in HRV when the IBS population was compared to healthy controls. Dividing the IBS sample into subgroups--according to their predominant bowel symptoms, the severity of clinical course, the presence of depressive symptoms, or a history of abuse in the past--revealed changes in autonomic functioning. CONCLUSIONS & INFERENCES: Patients with IBS appear to experience symptoms that may be the result of changes in ANS functioning. HRV measures in clinical routine may allow assessing these changes, but further studies performed in a standardized fashion should improve the validity of HRV measures for clinical research first.
