ABSTRACT

PLAIN ENGLISH SUMMARY: It is important for health care workers to know the needs and expectations of their patients. Therefore, service users have to be involved in research. To achieve a meaningful dialogue between service users, healthcare workers and researchers, participatory methods are needed. This paper describes how the application of a specific participatory methodology, Participatory Learning and Action (PLA) can lead to such a meaningful dialogue. In PLA all stakeholders are regarded as equal partners and collaborators in research.During 2011-2015, a European project called RESTORE used PLA in Austria, Greece, Ireland, The Netherlands and the UK to investigate how communication between primary health care workers and their migrant patients could be improved.Seventy eight migrants, interpreters, doctors, nurses and other key stakeholders (see Table 2) participated in 62 PLA sessions. These dialogues (involving discussions, activities, PLA techniques and evaluations) were generally 2-3 h long and were recorded and analysed by the researchers.Participants reported many positive experiences about their dialogues with other stakeholders. There was a positive, trusting atmosphere in which all stakeholders could express their views despite differences in social power. This made for better understanding within and across stakeholder groups. For instance a doctor changed her view on the use of interpreters after a migrant explained why this was important. Negative experiences were rare: some doctors and healthcare workers thought the PLA sessions took a lot of time; and despite the good dialogue, there was disappointment that very few migrants used the new interpreting service. ABSTRACT: Background In order to be effective, primary healthcare must understand the health needs, values and expectations of the population it serves. Recent research has shown that the involvement of service users and other stakeholders and gathering information on their perspectives can contribute positively to many aspects of primary healthcare. Participatory methodologies have the potential to support engagement and dialogue between stakeholders from academic, migrant community and health service settings. This paper focuses on a specific participatory research methodology, Participatory Learning and Action (PLA) in which all stakeholders are regarded as equal partners and collaborators in research.Our research question for this paper was: "Does the application of PLA lead to meaningful engagement of all stakeholders, and if so, what elements contribute to a positive and productive inter-stakeholder dialogue?". Methods We explored the use of PLA in RESTORE, a European FP7-funded project, during 2011-2015 in 5 countries: Austria, Greece, Ireland, the Netherlands and the UK. The objective of RESTORE was to investigate and support the implementation of guidelines and training initiatives (G/TIs) to enhance communication in cross-cultural primary care consultations with migrants.Seventy eight stakeholders (migrants, interpreters, doctors, nurses and others - see Table 2) participated in a total of 62 PLA sessions (discussions, activities, evaluations) of approximately 2-3 h' duration across the five sites. During the fieldwork, qualitative data were generated about stakeholders' experiences of engagement in this dialogue, by means of various methods including participatory evaluations, researchers' fieldwork reports and researcher interviews. These were analysed following the principles of thematic analysis. Results Stakeholders involved in PLA inter-stakeholder dialogues reported a wide range of positive experiences of engagement, and very few negative experiences. A positive atmosphere during early research sessions helped to create a sense of safety and trust. This enabled stakeholders from very different backgrounds, with different social status and power, to offer their perspectives in a way that led to enhanced learning in the group - they learned with and from each other. This fostered shifts in understanding - for example, a doctor changed her view on interpreted consultations because of the input of the migrant service-users. Conclusion PLA successfully promoted stakeholder involvement in meaningful and productive inter-stakeholder dialogues. This makes it an attractive approach to enhance the further development of health research partnerships to advance primary healthcare.

ABSTRACT

BACKGROUND: Cross-cultural communication in primary care is often difficult, leading to unsatisfactory, substandard care. Supportive evidence-based guidelines and training initiatives (G/TIs) exist to enhance cross cultural communication but their use in practice is sporadic. The objective of this paper is to elucidate how migrants and other stakeholders can adapt, introduce and evaluate such G/TIs in daily clinical practice. METHODS: We undertook linked qualitative case studies to implement G/TIs focused on enhancing cross cultural communication in primary care, in five European countries. We combined Normalisation Process Theory (NPT) as an analytical framework, with Participatory Learning and Action (PLA) as the research method to engage migrants, primary healthcare providers and other stakeholders. Across all five sites, 66 stakeholders participated in 62 PLA-style focus groups over a 19 month period, and took part in activities to adapt, introduce, and evaluate the G/TIs. Data, including transcripts of group meetings and researchers' fieldwork reports, were coded and thematically analysed by each team using NPT. RESULTS: In all settings, engaging migrants and other stakeholders was challenging but feasible. Stakeholders made significant adaptations to the G/TIs to fit their local context, for example, changing the focus of a G/TI from palliative care to mental health; or altering the target audience from General Practitioners (GPs) to the wider multidisciplinary team. They also progressed plans to deliver them in routine practice, for example liaising with GP practices regarding timing and location of training sessions and to evaluate their impact. All stakeholders reported benefits of the implemented G/TIs in daily practice. Training primary care teams (clinicians and administrators) resulted in a more tolerant attitude and more effective communication, with better focus on migrants' needs. Implementation of interpreter services was difficult mainly because of financial and other resource constraints. However, when used, migrants were more likely to trust the GP's diagnoses and GPs reported a clearer understanding of migrants' symptoms. CONCLUSIONS: Migrants, primary care providers and other key stakeholders can work effectively together to adapt and implement G/TIs to improve communication in cross-cultural consultations, and enhance understanding and trust between GPs and migrant patients.

ABSTRACT

We explore the application of terahertz spectroscopic techniques for the remote determination of the water content of paper. The aim is the development of a rapid diagnostic imaging tool applicable in paper fabrication processes. THz radiation offers a high sensitivity for water, a good spatial resolution, and insensitivity to scattering at the paper surface. The advent of THz cameras makes fast large-area image detectors feasible. In this paper, we show for the case of a 0.6-THz fixed-frequency system, that the water content of paper can be determined with high accuracy. We demonstrate a quantitative (calibrated) method for determining the moisture content in paper based on extinction and phase measurements in the lower THz range with a spatial resolution in the mm-range and scanning times below two minutes.

ABSTRACT

We present a new approach of generating the several wavelengths required for color holography with coherence lengths in the range of several meters. Our proposed laser system consists of an argon-ion laser, which is equipped with broadband optics. Its main lasing lines include 457, 488, and 514 nm. Sufficient coherence length is achieved by means of an intracavity etalon. We report single-frequency operation at several competing wavelengths and the successful recording of multicolor holograms with the described laser system.

ABSTRACT

This article reviews and comments on the five categories of arguments used to defend zero tolerance with regard to sexual contacts resulting from the physician-patient relationship as summarised by Cullen. In addition it puts forward a hypothesis-"fear of loss by third party"-as a psychological explanation for the collective insistence on a zero tolerance policy.

ABSTRACT

BACKGROUND: Thaumetopoea processionea L. (order Lepidoptera), the oak processionary moth, is found in oak forests in most European countries. Its third to sixth larval instars are armed with poisonous hairs (setae) containing an urticating toxin (thaumetopoein) potentially harmful to humans. Because T. processionea infests trees at the edges of forests or standing alone people frequently come into contact with its setae. In the woodland bordering on the western suburbs of Vienna conditions favouring its increase have led to frequent outbreaks of lepidopterism. OBJECTIVES: To determine the incidence of lepidopterism in a suburban environment with three separate caterpillar-infested oak trees and to ascertain the frequency of the various symptoms of lepidopterism and the manner of contact with setae. METHODS: We conducted a telephone survey of all the households/institutions located within 500 m of the infested trees. To gain more information on patients' symptoms and on situations likely to lead to increased contact with setae we asked those who reported cutaneous reactions to complete a questionnaire. As part of the environmental study we described the outbreak site, examined patients and, with tape-strip samples taken from the surface of the soil, looked for setae persisting in the environment. RESULTS: Of 1025 people surveyed 57 (5.6%) reported one or more symptoms of lepidopterism: 55 (96%) reported pruritus, 54 (95%) dermatitis, eight (14%) conjunctivitis, eight (14%) pharyngitis and two (4%) respiratory distress. The questionnaire was returned by 37 (69%) of the individuals with dermatitis. Of those, 16% had reacted with weal formation, 49% with papular rash and 22% with toxic irritant dermatitis. In 13% of respondents it was not possible to define the reaction. The risk factor analysis showed that airborne contamination was the most important cause: 97% of people had frequently passed an infested tree, 57% lived near a tree (in a neighbouring garden) and 32% had a tree in their own garden. Direct contact with larvae was of minor importance (38%). In four of the tape-strip samples intact setae were identified 1 year after the infestation. CONCLUSIONS: Lepidopterism caused by T. processionea is a public health problem of increasing significance. In years with outbreaks of the pest it can reach epidemic proportions in communities located near infested trees. Contact with airborne setae was mainly responsible for the occurrence of the disease.

ABSTRACT

Pivmecillinam is a unique beta-lactam antimicrobial that has been used for the treatment of acute uncomplicated urinary infection for > 20 y. Since this agent was introduced, the quinolone antimicrobials have become widely used for the same indication. This study compared the efficacy of a 3-d regimen of pivmecillinam 400 mg b.i.d. with norfloxacin 400 mg b.i.d. Women aged between 18 and 65 y presenting with symptoms of acute cystitis of < 7 d duration were eligible for enrollment; 483 were randomized to receive pivmecillinam and 471 to receive norfloxacin. In each group, 30% of women had negative urine cultures prior to therapy. Bacteriologic cure at early post-therapy follow-up was achieved in 222/298 (75%) pivmecillinam patients and 276/302 (91%) norfloxacin patients [p < 0.001; 95% confidence interval (CI) 12.0-21.8]. Clinical cure/improvement at Day 4 following initiation of therapy was observed in 434/457 (95%) women who received pivmecillinam and 425/442 (96%) who received norfloxacin (p = 0.39; 95% CI 1.5-3.9). Early post-therapy (11 +/- 2 d) clinical cure was achieved in 360/437 women (82%) who received pivmecillinam and 381/433 (88%) who received norfloxacin (p = 0.019; 95% CI 0.9-10.3). In women aged < or = 50 y, early clinical cure rates were 294/351 (84%) for pivmecillinam and 299/340 (88%) for norfloxacin (p = 0.11; 95% CI 1.0-9.4). Adverse effects were similar for both regimens, and there was no evidence of the emergence of organisms of increasing resistance with therapy. Short-course therapy with norfloxacin was superior to that with pivmecillinam in terms of bacteriologic outcome, although differences in clinical outcome were less marked. In conclusion, short-course therapy with pivmecillinam is an effective empirical treatment for pre-menopausal women.

ABSTRACT

Fourteen patients were examined between 3 weeks and 11 years after implantation of an aortobifemoral vascular graft with 111In labelled leukocytes isolated with discontinuous gradient centrifugation. The camera acquisition was performed with a three phase technique (acquisitions at 30 min, 4 h and 24 h p.i.). The presence and extent of a graft or perigraft infection including complicating fistulas could be correctly diagnosed in six of eight patients with surgically proven infections. Leukocyte uptake index was calculated as 1.77 +/- 0.4 (30 min p.i.) and 2.4 +/- 0.7 (24 h p.i.). All infections could be diagnosed by 30 min p.i., fistulas only could be seen 24 h p.i. In two of eight patients, false positive results were observed. These patients suffered from suspected perigraft hematomas and noninfected aortic graft aneurysms. Both had a negative 30 min scan and a slight uptake in the late scans comparable to bone marrow activity. Six patients with fever of unknown origin showed true negative scans. There were no false negative scans. We conclude that only the leukocyte scan can diagnose the presence and the extent, including fistulas, of vascular graft infections. The three phase technique is recommended to localize the blood pool in the 30 min scan and to diagnose complications 24 h p.i. In cases of a negative 30 min scan and positive 4 h and 24 h scans, false positive results should be suspected. All infections have a leukocyte uptake index higher than 1.2.

ABSTRACT

The monoclonal anti-CEA F(ab')2 fragment MAb BW 431/31, labelled with 123I or 111In, was used for immunoscintigraphy (IS) in 9 patients with medullary cancer of the thyroid (CCC). The results of 11 studies lead to the following conclusions: When using radioiodine as a label for MAb in IS, potassium iodide is absolutely necessary to block the thyroid which is of special importance in patients with thyroid cancer; Preinjection of "cold" MAb reduces the relatively high unspecific uptake (especially in bone marrow) of MAb BW 431/31, which is of special importance for the antibody labelled with 111In; IS with MAb BW 413/31 in patients with CCC and elevated serum CEA is positive only in cases with large secondaries; and In patients with CCC and several manifestations of secondaries, only a single (large) metastasis may be apparent.

ABSTRACT

The frequency of indication for surgical resection of goitre was retrospectively analysed for 2100 thyroid examinations. During 1974/75 (group I) only scintigraphy was available in addition to clinical examination; in 1979/80 (group II) cytological criteria were added, and in 1983/84 (group III) ultrasound findings were available as well. There were 700 patients in each group. The proportion of scintigraphically negative nodules was largely the same in the three groups (I and II: 21%; III: 22%). Indication for operation was less common after the introduction of ultrasound (I: 56%; II: 55%; III: 44% of patients with scintigraphically cold nodules). In particular, there was a decrease in the proportion of those nodules not definitely considered benign which would have required histological diagnosis (I: 32%; II: 18%; III: 8%). The results underline the special place of small-needle biopsy and, especially, ultrasound examination of the thyroid, in addition to clinical and scintigraphic findings, in providing the indication for and planning of operative nodular goitre resection.

ABSTRACT

Scintigraphy, sonography and fine needle cytology have the best accuracy in the evaluation of a cold nodular goitre. In 2,100 investigations on nodular goitre, it could be found that the incidence of the prophylactic operation for histological diagnosis decreased more than half. On the other hand, with the precise diagnosis the surgeon was able to perform thyroidectomy for thyroid cancer in the first operation. Thus complications of thyroidectomy (paralysis of the recurrent laryngeal nerve, tetany, residual thyroid tissue) could be reduced.

ABSTRACT

In a retrospective analysis in patients with differentiated thyroid carcinoma, the diagnostic validities of 131I whole-body scans and radioimmunologic determinations of thyroglobulin (hTg) are compared with special regard to late metastases. Metastases were found in 83 out of 311 patients with differentiated thyroid carcinoma. In two thirds of the cases, these were primary metastases while in the remaining third of the cases, metastases developed in later follow-up with a mean time of latency of 3.3 years. While about 70% of the early metastases could bei detected by 131I scintigraphy, this percentage amounted to only 40% in late metastases. With a diagnostic sensitivity of 90%, hTg-RIA was clearly superior in the detection of early as well as of late metastases. hTg was measurable, however, only in iatrogenous hypothyroidism in 4 out of 49 cases. Based on these results and an analysis of the literature, a program for follow-up of differentiated thyroid carcinoma is proposed. The hTg-RIA is thereby used as an alternative to 131I scintigraphy in the late phase of follow-up after complete ablation of any thyroid tissue.

ABSTRACT

Part II of the study concerning the clinical applicability of direct and indirect parameters for free thyroxine evaluates the diagnostic accuracy of the FT4-RIAs ImmoPhase, GammaCoat, Liquisol, Amerlex and LisoPhase in relation to FT4 index and T4/TBG ratio. This comparison of methods is done on a thoroughly classified collection (n = 640) of patients with normal and impaired thyroid function including patients with binding protein anomalies (pregnancy, estrogen-medication, phenytoin therapy, renal protein loss). FT4 normal ranges of a given kit harmonize well with data of the manufacturers and of the literature. On the other hand, the normal ranges of the various kits are not comparable. The differentiation of euthyroidism from hyper- or hypothyroidism can be made without problems using any of these methods, with the exception of the FT4-RIA GammaCoat. As expected, patients with euthyroid goiter show, on the average, slightly lower parameters for FT4. In pregnancy all direct and indirect parameters for FT4 have a tendency to lower values after the first trimester. This trend is most distinct for the T4/TBG ratio. A weak negative correlation of FT4 parameters with basal TSH, which does not exceed the upper normal range, however, can be interpreted in the sense of a relative hypothyroxinemia. Under contraceptive estrogen medication FT4 parameters do not fall outside the normal range, with the exception of the FT4-RIA ImmoPhase assay which yields a significantly increased frequency of high FT4 levels. On therapy with phenytoin FT4 values are generally lower than in controls. FT4 parameters in patients with renal protein loss of more than 2 g daily do not behave uniformly. While three of the FT4-RIAs tested (ImmoPhase, GammaCoat, Amerlex) show a tendency to lower values, the results of the remaining FT4 parameters do not differ significantly from the distribution of normals. The study leads to the conclusion that indirect FT4 parameters are still useful in the diagnosis of thyroid function; currently available FT4 radioimmunoassays may yield comparable results. With regard to the varying quality of the various commercial test kits, the choice between FT4-RIAs and indirect FT4 parameters does not depend primarily on clinical but on technical viewpoints.

ABSTRACT

The basic purpose of this work was to find a simple and economic method to control and eliminate the presence of alkaloids, as detected by organoleptic or toxicity tests, in Lupinus mutabilis, S. (tarhui) seeds. Taking advantage of the physical and chemical properties of the seeds, they were subjected to four methods of extraction; b) chemical treatment; c) extraction with two solvents, and d) treatment with a modified water-heat process. The results indicated that the most adequate method was the water-heat modified treatment, which showed a yield of 85% and a debittering efficiency of 98.6%, figures which were above those obtained with any of the other treatments studied. The final product had a bland taste without traces of bitterness and a 32% concentration of protein in the kayra line. Amino acid content showed this product to have an unusual high lysine content.
