Australian doctors' beliefs and practice regarding Helicobacter pylori

Objective: To determine beliefs and behaviours of Australian doctors regarding Helicobacter pylori. Design: Anonymous reply-paid postal survey mailed in December 1995 and again in March 1996. Subjects: All members on the mailing lists of the Gastroenterological Society of Australia Endoscopy Section (n = 397) and the Australian Society of Infectious Diseases (n = 264; those without medical qualifications were asked not to reply), and 400 general practitioners (GPs) randomly selected from the Royal Australian College of General Practitioners. Main outcome measures: Differences between specialist groups in belief in a causative association between H. pylori and peptic disease and in use of eradication therapy and pre- and post-treatment testing for H. pylori. Results: 92.6% of doctors believed H. pylori causes duodenal ulcer, with GPs significantly less likely to believe than gastroenterologists (odds ratio [OR], 0.22; 95% confidence interval [CI], 0.00-0.81). In duodenal ulcer, 93.4% of doctors believed H. pylori eradication therapy should be given, but fewer (83.4%) claimed to give it always or mostly, with GPs less likely to report giving it than gastroenterologists (OR, 0.06; 95% CI, 0.02-0.19). For non-ulcer dyspepsia, gastrointestinal surgeons were more likely than gastroenterologists to believe in a causative link with H. pylori (OR, 5.6; 95% CI, 3.0-10.7) and in a need for eradication therapy (OR, 3.6; 95% CI, 1.7-7.7). Most doctors (79.3%) believed in confirming the presence of H. pylori before eradication therapy in duodenal ulcer. Only 51.6% believed post-eradication testing necessary (45.5%), yet 79.1% reported performing it. Conclusions: Significant differences exist between specialist groups in beliefs and self-reported behaviours regarding H. pylori.

Attitudes and practices of general practitioners in the diagnosis and management of attention-deficit/hyperactivity disorder

Objective: To assess understanding of, and actual and potential roles in management of attention-deficit/hyperactivity disorder (ADHD) among GPs. Methods: A cross-sectional questionnaire survey of Queensland GPs selected randomly from the Royal Australian College of General Practitioners directory of members was carried out. Main outcome measures were knowledge levels of ADHD, current management practices, referral patterns and self-perceived information and training needs. Results: Three hundred and ninety-nine GPs returned a completed questionnaire (response rate 76%). Roles identified by GPs were: the provisional diagnosis of ADHD and referral to specialist services for confirmation of the diagnosis and initiation of management; assistance with monitoring progress once a management plan was in place; education of the child and their family regarding the disorder; and liaison with the school where necessary. Perceived barriers to increased involvement of GPs were: time and resource constraints of general practice; concerns regarding abuse and addiction liability of prescription stimulants; complex diagnostic issues associated with childhood behavioural problems; and lack of training and education regarding ADHD. Conclusions: General practitioners identify a role for themselves in ADHD care that is largely supportive in nature and involves close liaison with specialist services.

Brazilian doctors' perspective on the second opinion strategy before a C-section

OBJECTIVE: To describe the opinion of doctors who participated in the Latin American Study on Cesarean section in Brazil regarding the second opinion strategy when faced with the decision of performing a C-section. METHODS: Seventy-two doctors from the hospitals where the study took place (where the second opinion was routinely sought) and 70 from the control group answered a pre-tested self-administered structured questionnaire. Descriptive tables were prepared based on the frequency of relevant variables on opinion of physicians regarding: effectiveness of the application of the second opinion strategy; on whether they would recommend implementation of this strategy and reasons for not recommending it in private institutions; feasibility of the strategy implementation and reasons for not considering this implementation feasible in private institutions. RESULTS: Half of the doctors from the intervention hospitals (50%) and about two thirds of those in the control group (65%) evaluated the second opinion as being or having the potential of being effective/very effective in their institutions. The great majority of those interviewed from both intervention and control hospitals considered this strategy feasible in public (87% and 95% respectively) but not in private hospitals (64% and 70% respectively), mainly because in the latter the doctors would not accept interference from a colleague in their decision-making process. CONCLUSION: Although the second opinion strategy was perceived as effective in reducing C-section rates, doctors did not regard it feasible outside the public health system in Brazil.

Work, malaise, and well-being in Spanish and Latin-American doctors

ABSTRACT OBJECTIVE To analyze the relations between the meanings of working and the levels of doctors work well-being in the context of their working conditions. METHOD The research combined the qualitative methodology of textual analysis and the quantitative one of correspondence factor analysis. A convenience, intentional, and stratified sample composed of 305 Spanish and Latin American doctors completed an extensive questionnaire on the topics of the research. RESULTS The general meaning of working for the group located in the quartile of malaise included perceptions of discomfort, frustration, and exhaustion. However, those showing higher levels of well-being, located on the opposite quartile, associated their working experience with good conditions and the development of their professional and personal competences. CONCLUSIONS The study provides empirical evidence of the relationship between contextual factors and the meanings of working for participants with higher levels of malaise, and of the importance granted both to intrinsic and extrinsic factors by those who scored highest on well-being.

Careers, identities and professionalization. A study on doctors about their social representations related to the labor market today and its foreseeable future

This study is in line with the analyses of university and working career in their interaction in relation with conditioning factors. It comprises two central issues: the issue of identity bound to the issue of professionalization within the domain of training and employment. Nowadays, professionalization of the individuals, inside a troubled occupational world, demands the implementation of mechanisms favoring the development of both the individuals and the institution in which they work. All this has an impact at the local, regional and even national levels. Three levels of analysis interplay from a sui generis perspective: macro-meso-micro-macro (Aparicio, 2005; 2007a; 2007b, 2013a, 2014, 2015 b, d – See the Three- Dimensional Spiral of Sense Theory). The aim was to be aware of the doctors’ representations regarding the value of such degree under the present “degree devaluation”, and its impact on the professional future as well as on the core issues of the labor market which need urgent measures with a view to a belter interaction between the two systems. The methodology used was quanti-qualitative (semi-structured questionnaires, interviews, and hierarchical evocations). The population consisted of doctors (2005-2012) from the National University of Cuyo, in Argentina. The results helped us understand the nucleus of such representations and the peripheral aspects by career and institution, thus revealing professional and disciplinary identities. The professional identities show the situated needs in terms of professionalization within the different contexts and, particularly, within the labor market.

Bioluminescent sensor proteins for point-of-care therapeutic drug monitoring.

For many drugs, finding the balance between efficacy and toxicity requires monitoring their concentrations in the patient's blood. Quantifying drug levels at the bedside or at home would have advantages in terms of therapeutic outcome and convenience, but current techniques require the setting of a diagnostic laboratory. We have developed semisynthetic bioluminescent sensors that permit precise measurements of drug concentrations in patient samples by spotting minimal volumes on paper and recording the signal using a simple point-and-shoot camera. Our sensors have a modular design consisting of a protein-based and a synthetic part and can be engineered to selectively recognize a wide range of drugs, including immunosuppressants, antiepileptics, anticancer agents and antiarrhythmics. This low-cost point-of-care method could make therapies safer, increase the convenience of doctors and patients and make therapeutic drug monitoring available in regions with poor infrastructure.

Underreporting of needlestick and sharps injuries among healthcare workers in a Swiss University Hospital.

OBJECTIVES: To determine 1) rates of needlestick and sharps injuries (NSSIs) not reported to occupational health services, 2) reasons for underreporting and 3) awareness of reporting procedures in a Swiss university hospital. MATERIALS AND METHODS: We surveyed 6,367 employees having close clinical contact with patients or patient specimens. The questionnaire covered age, sex, occupation, years spent in occupation, history of NSSI during the preceding twelve months, NSSI reporting, barriers to reporting and knowledge of reporting procedures. RESULTS: 2,778 questionnaires were returned (43.6%) of which 2,691 were suitable for analysis. 260/2,691 employees (9.7%) had sustained at least one NSSI during the preceding twelve months. NSSIs were more frequent among nurses (49.2%) and doctors performing invasive procedures (IPs) (36.9%). NSSI rate by occupation was 8.6% for nurses, 19% for doctors and 1.3% for domestic staff. Of the injured respondents, 73.1% reported all events, 12.3% some and 14.6% none. 42.7% of doctors performing invasive procedures (IPs) underreported NSSIs and represented 58.6% of underreported events. Estimation that transmission risk was low (87.1%) and perceived lack of time (34.3%) were the most common reasons for non-reporting. Regarding reporting procedures, 80.1% of respondents knew to contact occupational health services. CONCLUSION: Doctors performing IPs have high rates of NSSI and, through self-assessment that infection transmission risk is low or perceived lack of time, high rates of underreporting. If individual risk analyses underestimate the real risk, such underreporting represents a missed opportunity for post-exposure prophylaxis and identification of hazardous procedures. Doctors' training in NSSI reporting merits re-evaluation.

Prevalence of Burnout syndrome in health professionals of an onco-hematological pediatric hospital

OBJECTIVE To identify the prevalence of Burnout Syndrome in medical professionals, nurses and nursing technicians working in an Onco-Hematological Pediatric Hospital in São Paulo. METHOD An exploratory, descriptive study with cross-sectional design and quantitative approach, with a sample of 188 health professionals. Data were collected using two self-report instruments: the Maslach Burnout Inventory (MBI-HSS) which is a biosocial data form, and a non-participant observation guide. RESULTS High depersonalization for nurses (29.8%), low job performance for physicians (27.8%), and of nursing technicians (25.5%). High scores were identified in at least two domains of Burnout in 19.2% of nurses, 16.8% of nursing technicians, and 16.6% of doctors. CONCLUSION Health professionals are highly vulnerable to each of the dimensions of Burnout syndrome - namely emotional exhaustion, alienation, and low job performance/satisfaction- in the hospital work.

The role of title insurance under recording and registration

This article outlines a transaction cost theory of title insurance andanalyses the role it plays in countries with recording and registrationof land titles. Title insurance indemnifies real estate right holdersfor losses caused by pre-existing title defects that are unknown whenthe policy is issued. It emerged to complement the errors and omissions insurance of professionals examining title quality. Poor organizationof public records led title insurers in the USA to integrate titleexamination and settlement services. Their residual claimant statusmotivates insurers to screen, cure and avoid title defects. Firmsintroducing title insurance abroad produce little information on titlequality, however. Their policies are instead issued on a casualty basis,complementing and enforcing the professional liability of conveyancers.Future development in markets with land registration is uncertainbecause of adverse selection, competitive reactions from establishedconveyancers and the ability of larger banks to self-insure title risks.

Population-based registration of phenotypic anatomic and familial data for melanoma: results from a Swiss multicentric study

CONTEXT AND OBJECTIVES: A multicentric study was set up to assess the feasibility for Swiss cancer registries of actively retrieving 3 additional variables of epidemiological and a etiological relevance for melanoma, and of potential use for the evaluation of prevention campaigns. MATERIAL AND METHODS: The skin type, family history of melanoma and precise anatomical site were retrieved for melanoma cases registered in 5 Swiss cantons (Neuchâtel, St-Gall and Appenzell, Vaud and Wallis) over 3 to 6 consecutive years (1995-2002). Data were obtained via a short questionnaire administered by the physicians - mostly dermatologists - who originally excised the lesions. As the detailed body site was routinely collected in Ticino, data from this Cancer Registry were included in the body site analysis. Relative melanoma density (RMD) was computed by the ratio of observed to expected numbers of melanomas allowing for body site surface areas, and further adjusted for site-specific melanocyte density. RESULTS: Of the 1,645 questionnaires sent, 1,420 (86.3%) were returned. The detailed cutaneous site and skin type were reliably obtained for 84.7% and 78.7% of questionnaires, and family history was known in 76% of instances. Prevalence of sun-sensitive subjects and patients with melanoma affected first-degree relatives, two target groups for early detection and surveillance campaigns were 54.1% and 3.4%, respectively. After translation into the 4th digit of the International Classification of Diseases for Oncology, the anatomical site codes from printed (original information) and pictorial support (body chart from the questionnaire) concurred for 94.6% of lesions. Discrepancies occurred mostly for lesions on the upper, outer part of the shoulder for which the clinician's textual description was "shoulder blade". This differential misclassification suggests under-estimation by about 10% of melanomas of the upper limbs and an over-estimation of 5% for truncal melanomas. Sites of highest melanoma risk were the face, the shoulder and the upper arm for sexes, the back for men and the leg for women. Three major features of this series were: (1) an unexpectedly high RMD for the face in women (6.2 vs 4.2 in men), (2) the absence of a male predominance for melanomas on the ears, and (3) for the upper limbs, a steady gradient of increasing melanoma density with increasing proximity to the trunk, regardless of sex. DISCUSSION AND CONCLUSION: The feasibility of retrieving the skin type, the precise anatomical location and family history of melanoma in a reliable manner was demonstrated thanks to the collaboration of Swiss dermatologists. Use of a schematic body drawing improves the quality of the anatomical site data and facilitate the reporting task of doctors. Age and sex patterns of RMD paralleled general indicators of sun exposure and behaviour, except for the hand (RMD=0.2). These Swiss results support some site or sun exposure specificity in the aetiology of melanoma.

Mesure de la pression artérielle: meilleur moyen d'évaluer le risque cardiovasculaire [Measurement of blood pressure: best way to assess cardiovascular risk?]

Measurement of the blood pressure by the physician remains an essential step in the evaluation of cardiovascular risk. Ambulatory measurement and self-measurement of blood pressure are ways of counteracting the "white coat" effect which is the rise in blood pressure many patients experience in the presence of doctors. Thus, it is possible to define the cardiovascular risk of hypertension and identify the patients with the greatest chance of benefiting from antihypertensive therapy. However, it must be realised that normotensive subjects during their everyday activities and becoming hypertensive in the doctor's surgery, may become hypertensive with time, irrespective of the means used to measure blood pressure. These patients should be followed up regularly even if the decision to treat has been postponed.

Future of Internet News Portals after the Case of Delfi

The thesis analyzes liability of Internet news portals for third-party defamatory comments. After the case of Delfi AS v. Estonia, decided by the Grand Chamber of the European Court of Human Rights on 16 June 2015, a portal can be held liable for user-generated unlawful comments. The thesis aims at exploring consequences of the case of Delfi for Internet news portals’ business model. The model is described as a mixture of two modes of information production: traditional industrial information economy and new networked information economy. Additionally, the model has a generative comment environment. I name this model “the Delfian model”. The thesis analyzes three possible strategies which portals will likely apply in the nearest future. I will discuss these strategies from two perspectives: first, how each strategy can affect the Delfian model and, second, how changes in the model can, in their turn, affect freedom of expression. The thesis is based on the analysis of case law, legal, and law and economics literature. I follow the law and technology approach in the vein of ideas developed by Lawrence Lessig, Yochai Benkler and Jonathan Zittrain. The Delfian model is researched as an example of a local battle between industrial and networked information economy modes. The thesis concludes that this local battle is lost because the Delfian model has to be replaced with a new walled-garden model. Such a change can seriously endanger freedom of expression.
