Development of an education campaign to reduce delays in pre-hospital response to stroke

Background

Systematic reviews call for well-designed trials with clearly described intervention components to support the effectiveness of educational campaigns to reduce patient delay in stroke presentation. We herein describe the systematic development process of a campaign aimed to increase stroke awareness and preparedness.

Methods

Campaign development followed Intervention Mapping (IM), a theory- and evidence-based tool, and was articulated in two phases: needs assessment and intervention development. In phase 1, two cross-sectional surveys were performed, one aiming to measure stroke awareness in the target population and the other to analyze the behavioral determinants of prehospital delay. In phase 2, a matrix of proximal program objectives was developed, theory-based intervention methods and practical strategies were selected and program components and materials produced.

Results

In phase 1, the survey on 202 citizens highlighted underestimation of symptom severity, as in only 44% of stroke situations respondents would choose to call the emergency service (EMS). In the survey on 393 consecutive patients, 55% presented over 2 hours after symptom onset; major determinants were deciding to call the general practitioner first and the reaction of the first person the patient called. In phase 2, adult individuals were identified as the target of the intervention, both as potential “patients” and witnesses of stroke. The low educational level found in the patient survey called for a narrative approach in cartoon form. The family setting was chosen for the message because 42% of patients who presented within 2 hours had been advised by a family member to call EMS. To act on people’s tendency to view stroke as an untreatable disease, it was decided to avoid fear-arousal appeals and use a positive message providing instructions and hope. Focus groups were used to test educational products and identify the most suitable sites for message dissemination.

Conclusions

The IM approach allowed to develop a stroke campaign integrating theories, scientific evidence and information collected from the target population, and enabled to provide clear explanations for the reasons behind key decisions during the intervention development process.

Who Is a Cancer Survivor? A Systematic Review of Published Definitions

The term "cancer survivor" is commonly used by different persons, clinical institutions, academic bodies, and political organizations although it lacks of a unanimous and detailed definition. The objective of the study is to make a systematic review of published and proposed definitions of "cancer survivor." Utilizing a systematic search strategy with different strings of "cancer survivor," we searched the following databases: Medline (June 1975-June 2015), Scopus (all the years), Web of Science (all the years), Google Scholar (all the years), ERIC (all the years). This review suggests that there is not a unique definition of who is a "cancer survivor" and what is "cancer survivorship." However, the most widely used definition sees cancer survivorship as a process that begins at the moment of diagnosis and continues through the balance of life. This definition highlights psychological and legal patient's needs-as well as medical ones-to receive care and assistance from the beginning and, at the same time, it establishes valid criteria for making scientific and statistical sampling research. The extensive use of the term "cancer survivor" indicates that it is a significant term. This review has been written to outline the state of the art and it invites to reflect on a shared definition that could satisfy both clinical and research aspects. Implication for cancer survivors: this compendium of proposed definitions may improve communication among the many patients and patient organizations that use and work with this term.

Ambiguity and uncertainty tolerance, need for cognition, and their association with stress. A study among Italian practicing physicians

Medical practice is inherently ambiguous and uncertain. The physicians' ability to tolerate ambiguity and uncertainty has been proved to have a great impact on clinical practice. The primary aim of the present study was to test the hypothesis that higher degree of physicians' ambiguity and uncertainty intolerance and higher need for cognitive closure will predict higher work stress. Two hundred and twelve physicians (mean age = 42.94 years; SD = 10.72) from different medical specialties with different levels of expertise were administered a set of questionnaires measuring perceived levels of work-related stress, individual ability to tolerate ambiguity, stress deriving from uncertainty, and personal need for cognitive closure. A linear regression analysis was performed to examine which variables predict the perceived level of stress. The regression model was statistically significant [R² = .32; F(10,206) = 8.78, p ≤ .001], thus showing that, after controlling for gender and medical specialty, ambiguity and uncertainty tolerance, decisiveness (a dimension included in need for closure), and the years of practice were significant predictors of perceived work-related stress. Findings from the present study have some implications for medical education. Given the great impact that the individual ability to tolerate ambiguity and uncertainty has on the physicians' level of perceived work-related stress, it would be worth paying particular attention to such a skill in medical education settings. It would be crucial to introduce or to empower educational tools and strategies that could increase medical students' ability to tolerate ambiguity and uncertainty.

ABBREVIATIONS

JSQ: Job stress questionnaire; NFCS: Need for cognitive closure scale; PRU: Physicians' reactions to uncertainty; TFA: Tolerance for ambiguity.

Distress and Psychosocial Needs in Patients Accessing a Cancer Day Surgery Division: Implications for Clinical Decision Making

Introduction: The Distress Thermometer (DT) was built and validated for screening cancer patients for distress, as suggested by the National Comprehensive Cancer Network. The current work was designed to measure the rates of distress in a sample of patients being hospitalized in a multidisciplinary outpatient surgery clinic.

OBJECTIVE

To measure the rates of distress in a sample of patients referring to a multidisciplinary day surgery division in a comprehensive cancer center based in Northern Italy. Methods: A total of 177 patients were asked to fill in the (DT) before surgery. Results: Out of 177 patients, 154 (87%) patients completed the DT. While 13% of the patients indicated a total absence of distress, more than half of the sample declared a moderate or high distress. A total of 55% of patients presented at least three difficulties in the Problem List Checklist. Distress was not correlated with age or other medical and clinical variables. Number of emotional problems was the best predictor of distress at admission (β = 0.655, p = 0.000). Conclusion: Screening for distress in a day surgery multidisciplinary oncology division is feasible and a relevant percentage of patients can be identified as clinically distressed. Outcomes also highlight the impact of age and precise physical and psycho-social signs as prognostic indicators of clinically significant distress. Measurement of distress and associated problems list represent the preliminary endpoint toward adequate recommendations that contribute to taking care of distress in cancer patients in cost-effective clinical setting.

Optimistic bias in young adults for cancer, cardiovascular and respiratory diseases: A pilot study on smokers and drinkers

Optimistic bias defines the tendency for human beings to underrate risk when it pertains to themselves compared with their view of risk pertaining to other people in the same conditions. The aim of this work is to investigate the optimistic bias in risk perception and health-related behaviours for three specific conditions in a young adult sample: cancer, respiratory disorders and cardiovascular diseases. Young adults showed an optimistic bias related to cancer, and to cardiovascular diseases. Our findings suggest that optimistic bias is linked to specific behavioural patterns, largely widespread in young adults, such as tobacco cigarette smoking and alcohol consumption.

Research studies on patients' illness experience using the Narrative Medicine approach: a systematic review

OBJECTIVE

Since its birth about 30 years ago, Narrative Medicine approach has increased in popularity in the medical context as well as in other disciplines. This paper aims to review Narrative Medicine research studies on patients' and their caregivers' illness experience.

SETTING AND PARTICIPANTS

MEDLINE, Psycinfo, EBSCO Psychological and Behavioural Science, The Cochrane Library and CINAHL databases were searched to identify all the research studies which focused on the Narrative Medicine approach reported in the title, in the abstract and in the keywords the words 'Narrative Medicine' or 'Narrative-based Medicine'.

PRIMARY AND SECONDARY OUTCOME MEASURES

number of participants, type of disease, race and age of participants, type of study, dependent variables, intervention methods, assessment.

RESULTS

Of the 325 titles screened, we identified 10 research articles fitting the inclusion criteria. Our systematic review showed that research on Narrative Medicine has no common specific methodology: narrative in Medicine is used as an intervention protocol as well as an assessment tool. Patients' characteristics, types of disease and data analysis procedures differ among the screened studies.

CONCLUSIONS

Narrative Medicine research in medical practice needs to find clear and specific protocols to deepen the impact of narrative on medical practice and on patients' lives.

Pediatric Blood Cancer Survivors and Tobacco Use across Adolescence and Emerging Adulthood: A Narrative Review

Scholars underline the pivotal role of tobacco cigarette smoking in carcinogenesis process for blood tumors. A controversial debate is represented by the diffusion of tobacco use in young cancer survivors that had a previous diagnosis of blood tumor during the childhood. Compared with their peers, scientific evidence highlights that pediatric survivors have more difficult to give-up cigarette smoking. Furthermore, tobacco-smoking is frequently linked with others risk behaviors as drinking or substance abuse. In reviewing the main knowledge on this topic, authors affirm the need for increasing research on blood cancer survivors in order to depict psychological characteristics of pediatric blood cancer survivors. Improving health decision-making skills in young survivors could reduce the risk to adopt un-healthy behaviors and increase psychological wellbeing. Furthermore, authors propose tailored antismoking interventions based on the knowledge of the psychological and cognitive factors that support smoking during the transition toward emerging-adulthood.

Deoxycholic acid transformations catalyzed by selected filamentous fungi

More than 100 filamentous fungi strains, mostly ascomycetes and zygomycetes from different phyla, were screened for the ability to convert deoxycholic acid (DCA) to valuable bile acid derivatives. Along with 11 molds which fully degraded DCA, several strains were revealed capable of producing cholic acid, ursocholic acid, 12-keto-lithocholic acid (12-keto-LCA), 3-keto-DCA, 15β-hydroxy-DCA and 15β-hydroxy-12-oxo-LCA as major products from DCA. The last metabolite was found to be a new compound. The ability to catalyze the introduction of a hydroxyl group at the 7(α/β)-positions of the DCA molecule was shown for 32 strains with the highest 7β-hydroxylase activity level for Fusarium merismoides VKM F-2310. Curvularia lunata VKM F-644 exhibited 12α-hydroxysteroid dehydrogenase activity and formed 12-keto-LCA from DCA. Acremonium rutilum VKM F-2853 and Neurospora crassa VKM F-875 produced 15β-hydroxy-DCA and 15β-hydroxy-12-oxo-LCA, respectively, as major products from DCA, as confirmed by MS and NMR analyses. For most of the positive strains, the described DCA-transforming activity was unreported to date. The presented results expand the knowledge on bile acid metabolism by filamentous fungi, and might be suitable for preparative-scale exploitation aimed at the production of marketed bile acids.

The choice dilemma in chronic hematological conditions: Why choosing is not only a medical issue? A psycho-cognitive perspective

Research in cognitive psychology focused on risk perception and decision making was shown to facilitate treatment choice and patient's satisfaction with decision in a number of medical conditions, increasing perceived alliance between patient and physician, and adherence to treatment. However, this aspect has been mostly neglected in the literature investigating choice of treatment for chronic hematological conditions. In this paper, a patient centered model and a shared decision making (SDM) approach to treatment switch in chronic hematological conditions, in particular chronic myeloid leukemia, atrial fibrillation, and β-thalassemia is proposed. These pathologies have a series of implications requiring important decisions about new available treatments. Although new generation treatments may provide a significant improvement in patient's health and health-related quality of life (HrQoL), a significant percentage of them is uncertain about or refuse treatment switch, even when strongly suggested by healthcare guidelines. Possible cognitive and emotional factors which may influence decision making in this field and may prevent appropriate risk-and-benefits evaluation of new treatment approaches are reviewed. Possible adaptive strategies to improve quality of care, patient participation, adherence to treatment and final satisfaction are proposed, and implications relatively to new treatment options available are discussed.

What are judgment skills in health literacy? A psycho-cognitive perspective of judgment and decision-making research

OBJECTIVE

The aim of this review is to summarize current research relating to psychological processes involved in judgment and decision-making (JDM) and identify which processes can be incorporated and used in the construct of health literacy (HL) in order to enrich its conceptualization and to provide more information about people's preferences.

METHODS

The literature review was aimed at identifying comprehensive research in the field; therefore appropriate databases were searched for English language articles dated from 1998 to 2015.

RESULTS

Several psychological processes have been found to be constituents of JDM and potentially incorporated in the definition of HL: cognition, self-regulation, emotion, reasoning-thinking, and social perception.

CONCLUSION

HL research can benefit from this JDM literature overview, first, by elaborating on the idea that judgment is multidimensional and constituted by several specific processes, and second, by using the results to implement the definition of "judgment skills". Moreover, this review can favor the development of new instruments that can measure HL.

PRACTICAL IMPLICATIONS

Future researchers in HL should work together with researchers in psychological sciences not only to investigate the processes behind JDM in-depth but also to create effective opportunities to improve HL in all patients, to promote good decisions, and orient patients' preferences in all health contexts.

What Do Physicians Believe About the Way Decisions Are Made? A Pilot Study on Metacognitive Knowledge in the Medical Context

Metacognition relative to medical decision making has been poorly investigated to date. However, beliefs about methods of decision making (metacognition) play a fundamental role in determining the efficiency of the decision itself. In the present study, we investigated a set of beliefs that physicians develop in relation to the modes of making decisions in a professional environment. The Solomon Questionnaire, designed to assess metacognitive knowledge about behaviors and mental processes involved in decision making, was administered to a sample of 18 emergency physicians, 18 surgeons, and 18 internists. Significant differences in metacognitive knowledge emerged among these three medical areas. Physicians' self-reports about the decision process mirrored the peculiarities of the context in which they operate. Their metacognitive knowledge demonstrated a reflective attitude that is an effective tool during the decision making process.

Cognitive and psychological profiles in treatment compliance: a study in an elderly population with hemophilia

Elderly patients with hemophilia have to face new challenges linked to concomitant pathologies and concurrent use of different treatments. In order to promote optimal care in the elderly hemophilia population, this study is aimed to analyze treatment compliance in relation to the presence of comorbidities and the role of potential determinants that can affect compliance (positively or negatively), including health-related quality of life, cognitive decline, and sociodemographic parameters (eg, living situation, partnership, presence of caregivers). This will be an observational study of elderly patients with hemophilia (aged >60 years). Patients will be interviewed during their routine medical visits. The data interview will pertaining to several dimension of treatment management. This study will detect more vulnerable patients with special care needs and will highlight psychological factors that should be considered for future psychosocial interventions.

A Cohort Pilot Study on HIV-Associated Neuropsychological Impairments in Hemophilia Patients

Despite advances in the management of HIV infection with the introduction of combination antiretroviral therapy, it is well known that HIV can directly infect the central nervous system and, as a result of such infection, neuropsychological impairments can be manifested. In this study, we tried to determine whether seropositivity was associated with a poor neuropsychological performance in patients with hemophilia and HIV. Such a cohort of patients is very often underrepresented and understudied in the HIV literature. To amend such a gap, we carried out an extensive neuropsychological evaluation on these patients, and compared their performance with that of a group of seronegative hemophilia patients. The results revealed that HIV infection in HIV-seropositive (HIV+) hemophilia patients was associated with deficits in attention, short-term memory, abstraction, and visual recognition. Such results are still preliminary and explorative due to the small cohort of patients enrolled. However, the results do seem to have some important implications for day-to-day functioning, as the level of impairment detected may cause difficulties in completing common everyday tasks such as maintaining adherence to complex medication regimens or maintaining social life activities. Continued research into the mechanisms related to HIV and neurocognitive dysfunction may provide targets for interventions that could have meaningful consequences in the real world for HIV hemophilia patients.

Cross-cultural adaptation of the stroke action test for Italian--speaking people

Background

Assessing the level of public stroke awareness is a prerequisite for development of community educational campaigns aimed at reducing prehospital delay of stroke patients. The Stroke Action Test (STAT) is a validated instrument specifically developed in the United States with the objective to assess the public’s readiness to respond to stroke. Our purpose was to perform the cross-cultural adaptation of the original version of STAT to be applied to the Italian population.

Methods

The process of cross-cultural adaptation has been performed according to guidelines, intended for questionnaires of self-report health status measures, following five steps: forward translation, synthesis, back translation, approval by an Expert Committee and test of the pre-final version. For this last step, 31 adults were asked to rate each item in terms of adequacy of content, clarity of wording and usefulness, according to a 3-point scale. The final version has been administered to a sample of 202 volunteers to assess its acceptability and reliability in terms of the internal consistency.

Results

The pre-final version of the STAT was developed taking into accounts few and minimal discrepancies between the two back translations and the original version of the instrument. Most items were judged as adequate, easy to understand and useful, according to the frequency of high scores (>50 %) given by the adaptation sample. As for further testing of the adapted final version, completeness of item response was very good. Distribution of scores ranged from 0 to 100 %, without any floor or ceiling effect, with a percentage of the lowest scoring of 1.5 % for the 28-item test and 2.5 % for the 21-item test and a percentage of the highest scoring of 1 % for both tests. Internal consistency was high for both the 28-item and 21-item tests (Cronbach alpha = 0.85 and 0.84, respectively).

Conclusions

The process used to perform the cross-cultural adaptation of the questionnaire was successful. The Italian version of STAT demonstrated good acceptability and psychometric properties and is now available to assess stroke awareness in Italian people.

Successful Portal Vein Stent Placement in a Child with Cavernomatous Replacement of the Portal Vein After Partial Liver Transplantation: The Importance of a Recognizable Portal Vein Remnant

Late portal vein thrombosis with cavernomatous replacement has been reported in 4.5% of pediatric patients who have undergone partial liver transplantation. In such cases, minimally invasive radiological treatments have a high failure rate. We report a successful case of percutaneous recanalization of the portal vein remnant, and subsequent stent placement, in a pediatric patient who underwent left lateral split liver transplantation with cavernomatous replacement of the portal vein.

Reticular erythematous mucinosis: a review of patients' characteristics, associated conditions, therapy and outcome in 25 cases

BACKGROUND

Reticular erythematous mucinosis (REM) is an uncommon disease, the nosology and specific characteristics of which are controversial because most reports deal with single cases or small series.

OBJECTIVES

To describe the characteristics of patients with REM regarding demographics, clinical and pathological features, comorbidities, treatment and course.

METHODS

A retrospective and prospective study was conducted on 25 patients diagnosed with REM in the setting of university-affiliated dermatology departments and dermatopathology centres.

RESULTS

Of the 25 patients with REM, 16 were women (sex ratio 2 : 1) and the mean age was 46 years. The roles of sun exposure and oral contraceptives were ambiguous. Associated diseases included hypertension (n = 4), malignancies (n = 3), autoimmune diseases (n = 3) and Borrelia infection (n = 1). Immunological studies (including serology and direct immunofluorescence) were noncontributory. The response to antimalarial treatment was good in > 80% of cases. Worsening or recurrence of the lesion after treatment discontinuation, or in the course of the disease, occurred in 31% of patients.

CONCLUSIONS

We present the largest REM case series to date. The reticular pattern with involvement of the midline of the chest and back, the predilection for middle-aged women, the controversial relationship with photosensitivity and the possible association with other conditions such as malignancies and thyroid dysfunctions are the main characteristics that makes REM a recognizable disease.

Interactive sections of an Internet-based intervention increase empowerment of chronic back pain patients: randomized controlled trial

Background

Chronic back pain (CBP) represents a significant public health problem. As one of the most common causes of disability and sick leave, there is a need to develop cost-effective ways, such as Internet-based interventions, to help empower patients to manage their disease. Research has provided evidence for the effectiveness of Internet-based interventions in many fields, but it has paid little attention to the reasons why they are effective.

Objective

This study aims to assess the impact of interactive sections of an Internet-based self-management intervention on patient empowerment, their management of the disease, and, ultimately, health outcomes.

Methods

A total of 51 patients were recruited through their health care providers and randomly assigned to either an experimental group with full access to the Internet-based intervention or a control group that was denied access to the interactive sections and knew nothing thereof. The intervention took 8 weeks. A baseline, a mid-term after 4 weeks, and a final assessment after 8 weeks measured patient empowerment, physical exercise, medication misuse, and pain burden.

Results

All patients completed the study. Overall, the intervention had a moderate effect (F_1.52=2.83, P=.03, η²=0.30, d=0.55). Compared to the control group, the availability of interactive sections significantly increased patient empowerment (midterm assessment: mean difference=+1.2, P=.03, d=0.63; final assessment: mean difference=+0.8, P=.09, d=0.44) and reduced medication misuse (midterm assessment: mean difference=−1.5, P=.04, d=0.28; final assessment: mean difference=−1.6, P=.03, d=−0.55) in the intervention group. Both the frequency of physical exercise and pain burden decreased, but to equal measures in both groups.

Conclusions

Results suggest that interactive sections as part of Internet-based interventions can positively alter patients’ feelings of empowerment and help prevent medication misuse. Detrimental effects were not observed.

Is There Evidence for Neurocognitive Dysfunctions in Patients with Postnatal HIV Infection? A Review on the Cohort of Hemophilia Patients

The debate regarding neurocognitive functions in the early stages of HIV infection is still ongoing; different studies have reached contrasting conclusions, probably because many of them take into account different cohorts of patients. A main distinction is between HIV seropositive patients infected perinatally, and those infected postnatally. The aim of this paper is to review results on neurocognitive dysfunctions and other types of neurological involvement in a specific cohort of HIV+ patients infected postnatally: hemophilia patients. Such a review is relevant, as HIV seropositive patients infected postnatally are understudied with respect to patients infected perinatally, and as the results of the few studies aiming at comparing them are contrasting. Taken together, the 11 studies reviewed suggest the presence of both long-term neurocognitive dysfunctions and neurological alterations, such as the presence of atrophic changes and lesions in the white matter. The current review may offer new research insights into the neurocognitive dysfunctions in HIV-patients, and on the nature of such dysfunctions.

A preliminary mixed-method investigation of trust and hidden signals in medical consultations

Background

Several factors influence patients' trust, and trust influences the doctor-patient relationship. Recent literature has investigated the quality of the personal relationship and its dynamics by considering the role of communication and the elements that influence trust giving in the frame of general practitioner (GP) consultations.

Objective

We analysed certain aspects of the interaction between patients and GPs to understand trust formation and maintenance by focusing on communication channels. The impact of socio-demographic variables in trust relationships was also evaluated.

Method

A cross-sectional design using concurrent mixed qualitative and quantitative research methods was employed. One hundred adults were involved in a semi-structured interview composed of both qualitative and quantitative items for descriptive and exploratory purposes. The study was conducted in six community-based departments adjacent to primary care clinics in Trento, Italy.

Results

The findings revealed that patients trusted their GP to a high extent by relying on simple signals that were based on the quality of the one-to-one communication and on behavioural and relational patterns. Patients inferred the ability of their GP by adopting simple heuristics based mainly on the so-called social “honest signals” rather than on content-dependent features. Furthermore, socio-demographic variables affected trust: less literate and elderly people tended to trust more.

Conclusions

This study is unique in attempting to explore the role of simple signals in trust relationships within medical consultation: people shape trust and give meaning to their relationships through a powerful channel of communication that orbits not around words but around social relations. The findings have implications for both clinicians and researchers. For doctors, these results suggest a way of thinking about encounters with patients. For researchers, the findings underline the importance of analysing some new key factors around trust for future investigations in medical practice and education.

Causes, coping, and culture: a comparative survey study on representation of back pain in three Swiss language regions

Introduction

This study intends to contribute to a research tradition that asks how causal attributions of illnesses affect coping behavior. Causal attributions are understood as the most important element of illness representations and coping as a means to preserve quality of life. The issue is applied to a condition so far often neglected in research on illness representations–back pain–and a third concept is added to the picture: culture.

Aim

The aim of this study is (a) to explore the causal factors to which persons with back pain attribute the further course of their illness, (b) to find out whether the attributed causes are predictors of coping maxims, and (c) to find out whether cultural factors affect attributions and coping and moderate the relationship between the two.

Methods

A total of 1259 gainfully employed or self-employed persons with recent episodes of back pain were recruited in the three language regions of Switzerland. They were asked to complete a structured online interview, measuring among many other variables attributed causes, coping maxims, and affiliation to one of the Swiss micro-cultures (German-, French- or Italian-speaking).

Results

Attributed causes of the illness that can be influenced by a patient go along with more active coping styles. Cultural affiliation impacts on coping maxims independently, but culture moderates the relationship of attributed causes and coping maxims only in two of twenty possible cases.

Implications

The results show that cultural differences can be analytically incorporated in the models of illness representations. Results may help to improve healthcare providers’ communication with patients and plan public health campaigns. The approach to micro-cultural differences and the substantive relationships between alterability of causes and activity in coping may help the further development of models of illness representations.

Hydroxylation of lithocholic acid by selected actinobacteria and filamentous fungi

Selected actinobacteria and filamentous fungi of different taxonomy were screened for the ability to carry out regio- and stereospecific hydroxylation of lithocholic acid (LCA) at position 7β. The production of ursodeoxycholic acid (UDCA) was for the first time shown for the fungal strains of Bipolaris, Gibberella, Cunninghamella and Curvularia, as well as for isolated actinobacterial strains of Pseudonocardia, Saccharothrix, Amycolatopsis, Lentzea, Saccharopolyspora and Nocardia genera. Along with UDCA, chenodeoxycholic (CDCA), deoxycholic (DCA), cholic (CA), 7-ketodeoxycholic and 3-ketodeoxycholic acids were detected amongst the metabolites by some strains. A strain of Gibberella zeae VKM F-2600 expressed high level of 7β-hydroxylating activity towards LCA. Under optimized conditions, the yield of UDCA reached 90% at 1g/L of LCA and up to 60% at a 8-fold increased substrate loading. The accumulation of the major by-product, 3-keto UDCA, was limited by using selected biotransformation media.

Efficacy of combined antiviral therapy with lamivudine and tenofovir in a liver transplanted girl with de novo hepatitis B virus infection

The management of de novo hepatitis B (HBV) infection in children after liver transplantation is not well defined. Because this infection may induce severe liver disease in the graft liver, an efficient antiviral therapy is desirable. Here, we describe the favorable viral outcome observed in a liver transplanted girl with de novo HBV infection following combination therapy with lamivudine and tenofovir.

Laparoscopic approach for an intra-abdominal kidney allograft nephrectomy after pediatric transplantation: a case report

We report a case of minimally invasive nephrectomy of a kidney transplanted into the abdominal cavity in a child. A 15-year-old girl underwent transplantation with a cadaveric donor kidney due to congenital pyelonephritis, vesicoureteral reflux, and secondary bladder atrophy. The transplant was complicated by hyperacute rejection, cytomegalovirus infection, and anastomotic stenosis of the Bricker neobladder. After recurrent urinary tract infections, the patient was reintroduced to hemodialysis in 2010. After pneumo-peritoneum, we placed 2 10-mm trocars in the hypochondrium and left side and 2 5-mm in the left iliac fossa and right upper quadrant. The transplanted kidney was skeletonized, the artery and vein were cut to the end-to-side anastomoses to the juxta-renal aorta and cava using an automatic 35-mm, stapler, and the ureter was dissected and closed with clips. Via a Pfannestiel minilaparotomy we extracted the allograft. The patient was discharged on the third postoperative day. After 4 months of follow-up, she is alive an on dialysis. Laparoscopic nephrectomy of a kidney transplanted into the abdominal cavity is feasible and safe in centers with skilled minimally invasive techniques.

The representation of risk in routine medical experience: what actions for contemporary health policy?

Background

The comprehension of appropriate information about illnesses and treatments, can have beneficial effects on patients’ satisfaction and on important health outcomes. However, it is questionable whether people are able to understand risk properly.

Aim

To describe patients’ representation of risk in common medical experiences by linking such a representation to the concept of trust. A further goal was to test whether the representation of risk in the medical domain is associated to the level of expertise. The third goal was to verify whether socio-demographic differences influence the representation of risk.

Methods

Eighty voluntary participants from 6 health-centers in northern Italy were enrolled to conduct a semi-structured interview which included demographic questions, term-associations about risk representation, closed and open questions about attitudes and perception of risk in the medical context, as well as about medical expertise and trust.

Results

The results showed that people do not have in mind a scientific definition of risk in medicine. Risk is seen as a synonym for surgery and disease and it is often confused with fear. However, general knowledge of medical matters helps people to have a better health management through risk identification and risk information, adoption of careful behaviors and tendency to have a critical view about safety and medical news. Finally, trust proved to be an important variable in risk representation and risk and trust were correlated positively.

Conclusions

People must receive appropriate information about the risks and benefits of treatment, in a form that they can understand and apply to their own circumstances. Moreover, contemporary health policy should empower patients to adopt an active self-care attitude. Methodologies to enhance people’s decision-making outcomes based on better risk communication should be improved in order to enable low literacy population as well elderly people to better understand their treatment and associated risk.

Out-of-reach obscure bleeding: single-balloon enteroscopy to diagnose and treat varices in hepaticojejunostomy after pediatric liver transplant

Obscure gastrointestinal (GI) bleeding is defined as bleeding from the GI tract that persists or recurs, with no obvious etiology, after esophagogastroduodenoscopy (EGD), colonoscopy, and radiologic evaluation of the small bowel. We present the case of a 17-yr-old girl who for two years had been suffering from recurrent episodes of melena and/or enterorrhagia. Fifteen yr earlier she had undergone a split-liver transplant with Roux-en-Y biliary reconstruction. A series of endoscopic and radiologic investigations had failed to find the source of the bleeding. Suspecting the presence of ectopic varices, we decided to perform single-balloon enteroscopy (SBE). We observed and aspirated a large amount of fresh red blood in the afferent loop until we found the hepaticojejunostomy. On the edge of the biliary-enteric anastomosis we observed a vascular lesion 5 mm in diameter. Judging this ectopic varix to be the source of bleeding, we placed two endoclips. The second clip placement caused varix rupture with a consequent massive hemorrhage, emergently and successfully treated with cyanoacrylate sclerotherapy. No episodes of rebleeding were observed, and no complications occurred during the entire hospital stay, and after six months of follow-up. This report highlights the importance of afferent loop examination in patients with obscure GI bleeding who have undergone liver transplant with Roux-en-Y biliary reconstruction.

Single-session percutaneous alcohol sclerotherapy for the treatment of isolated draining intrahepatic biliary duct in a five-month-old liver transplant recipient

The present paper describes the first reported successful use of a single session of percutaneous alcohol sclerotherapy for the treatment of an excluded segmental biliary duct in a five-month-old left lateral liver recipient. A concomitant stricture of the hepaticojejunostomy was also successfully treated using standard percutaneous balloon dilatation. The patient has remained in good general condition for the next 26 months.

Transjugular liver biopsy in pediatric patients with left split liver transplantation and severe coagulation impairment

The aim of this study is to report our experience in TJLB performed in pediatric patients who underwent partial LT using a left lateral segments graft. Eight consecutive TJLBs were performed in six patients with contraindication to percutaneous biopsy owing to severe coagulation impairment and ascites. All procedures were performed using an 18-gauge automated core needle biopsy. Median age of the patients was 44 months (range, 11-198). Median patients' weight was 13 kg (range, 8-45). Technical success was achieved in all cases without complications. The specimens were adequate for the diagnosis in all cases.

A trans-specific polymorphism in ZC3HAV1 is maintained by long-standing balancing selection and may confer susceptibility to multiple sclerosis

The human ZC3HAV1 gene encodes an antiviral protein. The longest splicing isoform of ZC3HAV1 contains a C-terminal PARP-like domain, which has evolved under positive selection in primates. We analyzed the evolutionary history of this same domain in humans and in Pan troglodytes. We identified two variants that segregate in both humans and chimpanzees; one of them (rs3735007) does not occur at a hypermutable site and accounts for a nonsynonymous substitution (Thr851Ile). The probability that the two trans-specific polymorphisms have occurred independently in the two lineages was estimated to be low (P = 0.0054), suggesting that at least one of them has arisen before speciation and has been maintained by selection. Population genetic analyses in humans indicated that the region surrounding the shared variants displays strong evidences of long-standing balancing selection. Selection signatures were also observed in a chimpanzee population sample. Inspection of 1000 Genomes data confirmed these findings but indicated that search for selection signatures using low-coverage whole-genome data may need masking of repetitive sequences. A case–control study of more than 1,000 individuals from mainland Italy indicated that the Thr851Ile SNP is significantly associated with susceptibility to multiple sclerosis (MS) (odds ratio [OR] = 1.47, 95% confidence intervals [CI]: 1.08–1.99, P = 0.011). This finding was confirmed in a larger sample of 4,416 Sardinians cases/controls (OR = 1.18, 95% CI: 1.037–1.344, P = 0.011), but not in a population from Belgium. We provide one of the first instances of human/chimpanzee trans-specific coding variant located outside the major histocompatibility complex region. The selective pressure is likely to be virus driven; in modern populations, this variant associates with susceptibility to MS, possibly via the interaction with environmental factors.

Analysis of a multiple nuclear dots pattern in a large cohort of dermatological patients

BACKGROUND

Anti-multiple nuclear dots (MND) antibodies are the markers of primary biliary cirrhosis (PBC), but can also be found in patients with other autoimmune diseases.

METHODS

We looked for MND in 9189 sera belonging to 6240 patients stored for autoimmune diseases with prevalent cutaneous features.

RESULTS

Fifty sera proved anti-MND-positive and came from 15 different patients: 6 had lupus erythematosus, 2 dermatomyositis, 2 lichen planus, 1 stroke, 1 telogen effluvium, 1 autoimmune thrombocytopenia, and 2 undifferentiated connective tissue disease.

CONCLUSIONS

Anti-MND antibodies can be found not only in patients with PBC, but in connective tissue diseases as well. They can be associated with other fluoroscopic patterns and their titers can vary over the years, never correlating with the disease activity or with particular cutaneous features. Although anti-MND antibodies found are directed to the Sp100 antigen of the nuclear dots, it remains unclear whether their molecular target is the same amino-acid domain as in PBC.

MDCT, MR and interventional radiology in biliary atresia candidates for liver transplantation

The multi-detector computed tomography (MDCT) scan and magnetic resonance (MR) of the abdomen play a key role in the work-up to liver transplantation (LT) by identifying congenital anomalies or cirrhosis-related modifications, conditions that can require changes in surgical technique. Moreover, the MDCT and MR scans allow identification of cirrhotic liver hepatic masses, extrahepatic porto-systemic shunts, eventual thrombosis of portal system and radiological signs of portal hypertension associated with biliary atresia (BA). The aim of this paper is to review MDCT, MR imaging and interventional radiology procedures performed to evaluate morphological changes and degree of portal hypertension in pediatric patients with end-stage liver disease secondary to BA, who are candidates for LT. Advances in the field of MR, MDCT and in percutaneous minimally invasive techniques have increased the importance of radiology in the management of pediatric patients with BA who are candidates for LT.

Combined split liver and kidney transplantation in a three-year-old child with primary hyperoxaluria type 1 and complete thrombosis of the inferior vena cava

PH1 is an inborn error of the metabolism in which a functional deficiency of the liver-specific peroxisomal enzyme, AGT, causes hyperoxaluria and hyperglycolic aciduria. Infantile PH1 is the most aggressive form of this disease, leading to early nephrocalcinosis, systemic oxalosis, and end-stage renal failure. Infantile PH1 is rapidly fatal in children unless timely liver-kidney transplantation is performed to correct both the hepatic enzyme defect and the renal end-organ damage. The surgical procedure can be further complicated in infants and young children, who are at higher risk for vascular anomalies, such as IVC thrombosis. Although recently a limited number of children with IVC thrombosis have underwent successful kidney transplantation, successful multi-organ transplantation in a child with complete IVC thrombosis is quite rare. We report here the interesting and technically difficult case of a three-yr-old girl with a complete thrombosis of the IVC, who was the recipient of combined split liver and kidney transplantation for infantile PH1. Although initial delayed renal graft function with mild-to-moderate acute rejection was observed, the patient rapidly regained renal function after steroid boluses, and was soon hemodialysis-independent, with good diuresis. Serum and plasma oxalate levels progressively decreased; although, to date they are still above normal. Hepatic and renal function indices were at, or approaching, normal values when the patient was discharged 15-wk post-transplant, and the patient continues to do well, with close and frequent follow-up. This is the first report of a successful double-organ transplant in a pediatric patient presenting with infantile PH1 complicated by complete IVC thrombosis.

Simple heuristics in over-the-counter drug choices: a new hint for medical education and practice

INTRODUCTION

Over-the-counter (OTC) drugs are widely available and often purchased by consumers without advice from a health care provider. Many people rely on self-management of medications to treat common medical conditions. Although OTC medications are regulated by the National and the International Health and Drug Administration, many people are unaware of proper dosing, side effects, adverse drug reactions, and possible medication interactions.

PURPOSE

This study examined how subjects make their decisions to select an OTC drug, evaluating the role of cognitive heuristics which are simple and adaptive rules that help the decision-making process of people in everyday contexts.

SUBJECTS AND METHODS

By analyzing 70 subjects' information-search and decision-making behavior when selecting OTC drugs, we examined the heuristics they applied in order to assess whether simple decision-making processes were also accurate and relevant. Subjects were tested with a sequence of two experimental tests based on a computerized Java system devised to analyze participants' choices in a virtual environment.

RESULTS

We found that subjects' information-search behavior reflected the use of fast and frugal heuristics. In addition, although the heuristics which correctly predicted subjects' decisions implied significantly fewer cues on average than the subjects did in the information-search task, they were accurate in describing order of information search. A simple combination of a fast and frugal tree and a tallying rule predicted more than 78% of subjects' decisions.

CONCLUSION

The current emphasis in health care is to shift some responsibility onto the consumer through expansion of self medication. To know which cognitive mechanisms are behind the choice of OTC drugs is becoming a relevant purpose of current medical education. These findings have implications both for the validity of simple heuristics describing information searches in the field of OTC drug choices and for current medical education, which has to prepare competent health specialists to orientate and support the choices of their patients.
