Misdiagnosis of vertebral fractures on local radiographic readings of the multicentre POINT (Prevalence of Osteoporosis in INTernal medicine) study

BACKGROUND

Osteoporotic vertebral fractures (VFs) are often misdiagnosed because asymptomatic and occurring in the absence of specific trauma. Further, diagnostic assessment of VFs may be suboptimal.

AIM OF THE STUDY

To assess the misdiagnosis of vertebral fractures on local radiographic readings in the cohort of patients enrolled in the POINT study.

METHODS

We enrolled hospitalised patients, admitted for any cause to the Internal Medicine Units of 37 hospitals participating to the cross-sectional previously published POINT study. The assessment of VFs was performed both by local radiologists and by two expert skeletal radiologists, by using semiquantitative method (SQ). To better evaluate mild vertebral deformities, the two central radiologists also used the algorithm-based qualitative assessment (ABQ).

RESULTS

The radiographs of 661 patients (401 females; mean age 75.8±8.0) were evaluated. The inter-reader percent agreement between two central expert radiologists per-vertebra assessment was excellent (99.78%; k=0.984; 95% CI, 0.977-0.991). Central reading identified 318/661 (48.1%) patients with at least one VF. Local and central readings agreed in 502/661 (75.9%) patients, resulting in a fair reproducibility (k=0.52; 95% confidence interval 0.44-0.59). Diagnostic performance parameters of local readings were: sensitivity 76.1%; specificity 75.8%; PPV 74.46%; NPV 77.38%). By examining 9254 vertebrae, central and local readers diagnosed 665 (7.2%) and 562 (6.1%) VFs respectively. Misdiagnosis (102 false positives and 205 false negatives) mainly occurred for mild VFs. Local readings identified correctly 460 out 665 VFs diagnosed by central readings, resulting in sensitivity of 69.2% and PPV of 81.8%.

CONCLUSIONS

Following a standardized protocol of acquisition techniques and of interpretation criteria, an excellent agreement between local and central readings for moderate and severe vertebral fractures resulted. However a significant amount of mild vertebral fractures, that are the most of VFs, were misdiagnosed by local radiologists. In order to improve VFs assessment, the radiologists should be trained and sensitized in relation to the relevant clinical significance of osteoporotic VFs identification.

Fertilizing a Patient Engagement Ecosystem to Innovate Healthcare: Toward the First Italian Consensus Conference on Patient Engagement

Currently we observe a gap between theory and practices of patient engagement. If both scholars and health practitioners do agree on the urgency to realize patient engagement, no shared guidelines exist so far to orient clinical practice. Despite a supportive policy context, progress to achieve greater patient engagement is patchy and slow and often concentrated at the level of policy regulation without dialoguing with practitioners from the clinical field as well as patients and families. Though individual clinicians, care teams and health organizations may be interested and deeply committed to engage patients and family members in the medical course, they may lack clarity about how to achieve this goal. This contributes to a wide "system" inertia-really difficult to be overcome-and put at risk any form of innovation in this filed. As a result, patient engagement risk today to be a buzz words, rather than a real guidance for practice. To make the field clearer, we promoted an Italian Consensus Conference on Patient Engagement (ICCPE) in order to set the ground for drafting recommendations for the provision of effective patient engagement interventions. The ICCPE will conclude in June 2017. This document reports on the preliminary phases of this process. In the paper, we advise the importance of "fertilizing a patient engagement ecosystem": an oversimplifying approach to patient engagement promotion appears the result of a common illusion. Patient "disengagement" is a symptom that needs a more holistic and complex approach to solve its underlined causes. Preliminary principles to promote a patient engagement ecosystem are provided in the paper.

Evaluation of the threshold value for the modified early warning score (MEWS) in medical septic patients: a secondary analysis of an Italian multicentric prospective cohort (SNOOPII study)

BACKGROUND

Due to aging and resources limitation, septic patients are often admitted to medical wards (MWs). Early warning deterioration is a relevant issue in this setting. Unfortunately, a suitable prognostic score has not been identified, yet.

AIM

To explore the ability of Modified Early Warning Score (MEWS) to predict the in-hospital mortality in septic patients admitted to MWs.

DESIGN

Secondary analysis of a multicentric prospective study.

METHODS

Consecutive septic patients with positive blood culture admitted to 31 Italian MWs were included. Baseline characteristics, clinics, isolates, rate of transfer to ICU, MEWS was collected on admission according to the study protocol. The accuracy of MEWS in predicting the in-hospital mortality was assessed with the area under the receiver-operating characteristic curves. Sensitivity, specificity, positive and negative predictive value (PPV and NPV), likelihood ratio (LR) were calculated for different MEWS cut-offs and age/comorbidities subgroups.

RESULTS

In total 526 patients were included in this analysis. Median MEWS was (range 0-11). In-hospital mortality was 14.8% and transfer to ICU 1.3%. Mortality progressively increased according to MEWS (3% in MEWS 0 vs. 27% in MEWS >5; Chi square for trend P < 0.05). The AUC of MEWS in predicting in-hospital mortality was 0.596 (95% CI, 0.524, 0.669). MEWS did not appear to have an adequate sensitivity, sensibility, PPV, NPV and LR both in the whole population and in the pre-specified subgroups.

CONCLUSIONS

Our findings do not seem to support the use of MEWS to predict the in-hospital mortality risk of sepsis in MWs.

Constipation-Predominant Irritable Bowel Syndrome Females Have Normal Colonic Barrier and Secretory Function

OBJECTIVES

The objective of this study was to determine whether constipation-predominant irritable bowel syndrome (IBS-C) is associated with changes in intestinal barrier and secretory function.

METHODS

A total of 19 IBS-C patients and 18 healthy volunteers (all females) underwent saccharide excretion assay (0.1 g ¹³C mannitol and 1 g lactulose), measurements of duodenal and colonic mucosal barrier (transmucosal resistance (TMR), macromolecular and Escherichia coli Bio-Particle translocation), mucosal secretion (basal and acetylcholine (Ach)-evoked short-circuit current (Isc)), in vivo duodenal mucosal impedance, circulating endotoxins, and colonic tight junction gene expression.

RESULTS

There were no differences in the in vivo measurements of barrier function between IBS-C patients and healthy controls: cumulative excretion of ¹³C mannitol (0-2 h mean (s.e.m.); IBS-C: 12.1 (0.9) mg vs. healthy: 13.2 (0.8) mg) and lactulose (8-24 h; IBS-C: 0.9 (0.5) mg vs. healthy: 0.5 (0.2) mg); duodenal impedance IBS-C: 729 (65) Ω vs. healthy: 706 (43) Ω; plasma mean endotoxin activity level IBS-C: 0.36 (0.03) vs. healthy: 0.35 (0.02); and in colonic mRNA expression of occludin, zonula occludens (ZO) 1-3, and claudins 1-12 and 14-19. The ex vivo findings were consistent, with no group differences: duodenal TMR (IBS-C: 28.2 (1.9) Ω cm² vs. healthy: 29.8 (1.9) Ω cm²) and colonic TMR (IBS-C: 19.1 (1.1) Ω cm² vs. healthy: 17.6 (1.7) Ω cm²); fluorescein isothiocyanate (FITC)-dextran (4 kDa) and E. coli Bio-Particle flux. Colonic basal Isc was similar, but duodenal basal Isc was lower in IBS-C (43.5 (4.5) μA cm^-2) vs. healthy (56.9 (4.9) μA cm^-2), P=0.05. Ach-evoked ΔIsc was similar.

CONCLUSIONS

Females with IBS-C have normal colonic barrier and secretory function. Basal duodenal secretion is decreased in IBS-C.

Integrated care in the management of chronic diseases: an Italian perspective

This letter provides a view on the issue of the organizational model of Primary Care Groups (PCGs), which represent a best practice in continuity and appropriateness of care for chronic patients. Our analysis aimed at estimating the impact of PCGs introduction in terms of efficiency and effectiveness. The results of our study showed a better performance of PCGs compared with the other General Practitioners of Local Health Authority Milano 1, supporting the conclusion that good care cannot be delivered without good organization of care.

^{7}Be(n,α)^{4}He Reaction and the Cosmological Lithium Problem: Measurement of the Cross Section in a Wide Energy Range at n_TOF at CERN

The energy-dependent cross section of the ^{7}Be(n,α)^{4}He reaction, of interest for the so-called cosmological lithium problem in big bang nucleosynthesis, has been measured for the first time from 10 meV to 10 keV neutron energy. The challenges posed by the short half-life of ^{7}Be and by the low reaction cross section have been overcome at n_TOF thanks to an unprecedented combination of the extremely high luminosity and good resolution of the neutron beam in the new experimental area (EAR2) of the n_TOF facility at CERN, the availability of a sufficient amount of chemically pure ^{7}Be, and a specifically designed experimental setup. Coincidences between the two alpha particles have been recorded in two Si-^{7}Be-Si arrays placed directly in the neutron beam. The present results are consistent, at thermal neutron energy, with the only previous measurement performed in the 1960s at a nuclear reactor. The energy dependence reported here clearly indicates the inadequacy of the cross section estimates currently used in BBN calculations. Although new measurements at higher neutron energy may still be needed, the n_TOF results hint at a minor role of this reaction in BBN, leaving the long-standing cosmological lithium problem unsolved.

MEDical wards Invasive Candidiasis ALgorithms (MEDICAL):Consensus proposal for management

INTRODUCTION

A majority of invasive Candida infections occur in medical wards; however, evidence for management in this setting is scarce and based primarily on the intensive care or surgical setting. On behalf of the Italian Society for Anti-Infective Therapy (SITA) and the Italian Federation of Associations of Hospital Doctors on Internal Medicine (FADOI), the MEDICAL group produced practical management algorithms for patients in internal medicine wards.

METHODS

The MEDICAL group panel, composed of 30 members from internal medicine, infectious disease, clinical pharmacology, clinical microbiology and clinical epidemiology, provided expert opinion through the RAND/UCLA method.

RESULTS

Seven clinical scenarios were constructed based on clinical severity and probability of invasive candidiasis. For each scenario, the appropriateness of 63 different diagnostic, imaging, management, or therapeutic procedures was determined in two Delphi rounds. The necessity for performing each appropriate procedure, was then determined in a third Delphi round. Results were summarized in algorithms.

DISCUSSION

The proposed algorithms provide internal medicine physicians and managers with an easy to interpret tool that is exhaustive, clear and suitable for adaption to individual local settings. Attention was paid to individual patient management and resource allocation.

Acute bacterial skin and skin structure infections in internal medicine wards: old and new drugs

Skin and soft tissue infections (SSTIs) are a common cause of hospital admission among elderly patients, and traditionally have been divided into complicated and uncomplicated SSTIs. In 2010, the FDA provided a new classification of these infections, and a new category of disease, named acute bacterial skin and skin structure infections (ABSSSIs), has been proposed as an independent clinical entity. ABSSSIs include three entities: cellulitis and erysipelas, wound infections, and major cutaneous abscesses This paper revises the epidemiology of SSTIs and ABSSSIs with regard to etiologies, diagnostic techniques, and clinical presentation in the hospital settings. Particular attention is owed to frail patients with multiple comorbidities and underlying significant disease states, hospitalized on internal medicine wards or residing in nursing homes, who appear to be at increased risk of infection due to multi-drug resistant pathogens and treatment failures. Management of ABSSSIs and SSTIs, including evaluation of the hemodynamic state, surgical intervention and treatment with appropriate antibiotic therapy are extensively discussed.

The Pathophysiology of Phagocytes

No survey of clinically important immunological phenomena would be complete without consideration of the functions of phagocytic cells. They play a pivotal role in the immune response by kiling microbes, by presenting antigens to lymphocytes and by serving as supportive, accessory cells to lymphocytes, at least partly by releasing soluble factors. The phagocytes of the body, professional and non professional, consist of two specialized groups of cells: granulocytes, which can be mobilized rapidly and which reach inflamed sites quickly and in large numbers, and which are highly efficient at dealing with many types of injury and infection but which have no capacity for differentiation and live only a short time; and the mononuclear phagocyte system consisting partly of motile cells which respond initially more slowly than neutrophils but which can differentiate in sites of inflammation into cells which are more efficient in various functions than the cells from which they originated. Many mononuclear phagocytes are fixed cells located in tissues where they act as trays or filters for material circulating through the tissue. Phagocytes, which usually function as the primary defender in infections, have also been implicated as effector cells in several conditions characterized by a destructive inflammatory response.

The Cytokine Network: Their Role in Physiopathology and Therapeutic Implications

Lymphocytes, accessory-endothelial-and inflammatory-cells produce a variety of soluble factors termed cytokines. These are regulatory molecules which appear after the immune response at all stages of lymphocyte development. They also have important regulatory influences on other haematopoietic cells. Rapid progress is being made through the use of gene cloned cytokines in understanding the complex interactions of these factors with many different cell types. New factors have been added to the cytokine network, and new functions reported for existing cytokines. The clinical implications in disease and the application of cytokines or their inhibitors in human disorders, cancer, infection and autoimmunity, has met with some success and many trials are currently in progress which should lead to more successful therapeutic strategies.

A model to improve the appropriateness in the management of acute poly-pathological patients: the acute complex care model

Improved care for acute diseases has increased mean age and the proportion of people affected by multiple chronic diseases, while mutated socioeconomic conditions augmented the number of elderly and socially frail subjects. Multi-morbid patients who require a global approach not fragmented care interventions and a close connection between health and social services are progressively growing. Acute complex care model (ACCM) is a model of integrated management of the frail patients when they need of acute hospital care. The name of our model - ACCM - just recalls the Chronic Care Model (CCM), designed for the dehospitalization of chronic patients by preventing acute exacerbations, representing the hospital counterpart of the CCM. The target population are acutely ill complex and polypathological patients (AICPPs), admitted to hospital and requiring high technological resources and continuous monitoring; the mission is improving the management of medical admissions through pre-defined intra-hospital tracks and a global, multidisciplinary, patientcentred approach. Nowadays, multiple uncoordinated specialists care for AICPPs who move from one ward to another, with dangerous loss of information and continuity. ACCM tries to overcome these problems by putting the internal medicine specialist as the only referent for that patient and the coordinator of the care team. According to a model of future hospital organized with different intensity settings, the Internal Medicine Wards (IMWs), caring for AICPPS, are organized in High Dependency Areas and Ordinary Areas. For both we present organizational and personnel standards that are lacking in daily practice. The epidemiological transition leading to a progressive increase in AICPPs requiring frequent hospitalization enhances the role of hospital internal medicine specialist in the coordination and delivery of care. The ACCM represents a practical response to this epochal change of roles. Medical and nursing staff standards and competencies has to be reviewed to ensure adequate care for these patients.

Prulifloxacin vs Levofloxacin for Exacerbation of COPD after Failure of Other Antibiotics

The chronic course and evolution of chronic obstructive pulmonary disease (COPD) is often characterized by periods of exacerbation of symptoms, which have a negative impact on the quality of life of patients, as well as on the evolution of COPD, and represent a significant cause of medical intervention and hospitalization. Very few data are available on the efficacy of rescue antibiotics in patients with acute exacerbation of COPD (AECOPD) unresponsive to previous treatment. The aim of this study was to evaluate the efficacy of two fluoroquinolones in AECOPD previously treated without success. The FADOI-FLOR study is a randomized, single-blind, non-inferiority comparison between levofloxacin and prulifloxacin. Primary end-point was "therapeutic success" at Day 10 of treatment, defined as disappearance of signs/symptoms or decrease of at least three points of a global score of symptomatology (maximum score = 15). 258 patients were enrolled (128 levofloxacin and 130 prulifloxacin), in 25 centers. A very high proportion of patients in the two groups had therapeutic success at Day-10 (levofloxacin 93.0% vs prulifloxacin 96.7%, population intention-to-treat; 94.6% vs 99.1%, population per-protocol). Earlier therapeutic success (within 7 days) was achieved in 32.0% and 36.2% of patients receiving levofloxacin or prulifloxacin, respectively. At 3-month follow-up, re-exacerbations occurred in 17.8% of patients treated with levofloxacin and 14.2% of those receiving prulifloxacin (p = 0.44). In conclusion, fluoroquinolones are very effective in the treatment of AECOPD resistant to other antibiotics.

Clinical Features, Short-Term Mortality, and Prognostic Risk Factors of Septic Patients Admitted to Internal Medicine Units: Results of an Italian Multicenter Prospective Study

Only a few studies provided data on the clinical history of sepsis within internal Medicine units. The aim of the study was to assess the short-term mortality and to evaluate the prognostic risk factors in a large cohort of septic patients treated in internal medicine units. Thirty-one internal medicine units participated to the study. Within each participating unit, all admitted patients were screened for the presence of sepsis. A total of 533 patients were included; 78 patients (14.6%, 95%CI 11.9, 18.0%) died during hospitalization; mortality rate was 5.5% (95% CI 3.1, 9.6%) in patients with nonsevere sepsis and 20.1% (95%CI 16.2, 28.8%) in patients with severe sepsis or septic shock. Severe sepsis or septic shock (OR 4.41, 95%CI 1.93, 10.05), immune system weakening (OR 2.10, 95%CI 1.12, 3.94), active solid cancer (OR 2.14, 95% CI 1.16, 3.94), and age (OR 1.03 per year, 95% CI 1.01, 1.06) were significantly associated with an increased mortality risk, whereas blood culture positive for Escherichia coli was significantly associated with a reduced mortality risk (OR 0.46, 95%CI 0.24, 0.88). In-hospital mortality of septic patients treated in internal medicine units appeared similar to the mortality rate obtained in recent studies conducted in the ICU setting.

Improving proprioceptive deficits after stroke through robot-assisted training of the upper limb: a pilot case report study

The purpose of this study was to determine whether a conventional robot-assisted therapy of the upper limb was able to improve proprioception and motor recovery of an individual after stroke who exhibited proprioceptive deficits. After robotic sensorimotor training, significant changes were observed in kinematic performance variables. Two quantitative parameters evaluating position sense improved after training. Range of motion during shoulder and wrist flexion improved, but only wrist flexion remained improved at 3-month follow-up. These preliminary results suggest that intensive robot-aided rehabilitation may play an important role in the recovery of sensory function. However, further studies are required to confirm these data.

Expression and function of the Scn5a-encoded voltage-gated sodium channel NaV 1.5 in the rat jejunum

BACKGROUND

The SCN5A-encoded voltage-gated sodium channel NaV 1.5 is expressed in human jejunum and colon. Mutations in NaV 1.5 are associated with gastrointestinal motility disorders. The rat gastrointestinal tract expresses voltage-gated sodium channels, but their molecular identity and role in rat gastrointestinal electrophysiology are unknown.

METHODS

The presence and distribution of Scn5a-encoded NaV 1.5 was examined by PCR, Western blotting and immunohistochemistry in rat jejunum. Freshly dissociated smooth muscle cells were examined by whole cell electrophysiology. Zinc finger nuclease was used to target Scn5a in rats. Lentiviral-mediated transduction with shRNA was used to target Scn5a in rat jejunum smooth muscle organotypic cultures. Organotypic cultures were examined by sharp electrode electrophysiology and RT-PCR.

KEY RESULTS

We found NaV 1.5 in rat jejunum and colon smooth muscle by Western blot. Immunohistochemistry using two other antibodies of different portions of NaV 1.5 revealed the presence of the ion channel in rat jejunum. Whole cell voltage-clamp in dissociated smooth muscle cells from rat jejunum showed fast activating and inactivating voltage-dependent inward current that was eliminated by Na(+) replacement by NMDG(+) . Constitutive rat Scn5a knockout resulted in death in utero. NaV 1.5 shRNA delivered by lentivirus into rat jejunum smooth muscle organotypic culture resulted in 57% loss of Scn5a mRNA and several significant changes in slow waves, namely 40% decrease in peak amplitude, 30% decrease in half-width, and 7 mV hyperpolarization of the membrane potential at peak amplitude.

CONCLUSIONS & INFERENCES

Scn5a-encoded NaV 1.5 is expressed in rat gastrointestinal smooth muscle and it contributes to smooth muscle electrophysiology.

Clinical governance and clinical competence to support new scenarios and role of internal medicine

The complex patient, that has often multiple, chronic and progressive disorders, that’s undergone at polytherapy, should be evaluated totally with respect not only to medical side, but also to psychological and clinical side. The shortage of specialists in disciplines that require technical skills, obtained by training and performing a sufficient number of annual procedures, contributes to the need for reorganizing health care; in this background the Internist devolves less time to charitable activities in favor of competences related to the processes. The knowledge of the clinical governance (CG) should be the common heritage of all the actors of the health system, that need to be made up of professionals able to coordinate and make easy the implementation and the spread the CG culture. At least initially we propose to focus the testing strictly within the medical department. As already mentioned above, the natural Internist predisposition, cultural and training, leads him to a multidisciplinary vision of medicine that allowing to acquire more easily the tools that make up the structure of CG, being able to facilitate the application. The acquisitions of professional competence and clinical governance play a key role in the Internist culture. The purpose of an Internist with professional skills and managerial capacity, is to act within the department to facilitate and simplify the horizontal interaction among other similar corporate structures and to help the Management to improve structural and clinical appropriateness in Hospital and to better the relations between hospital and territory, identifying the critical issues and the possible solutions.

Under-detection of delirium and impact of neurocognitive deficits on in-hospital mortality among acute geriatric and medical wards

BACKGROUND

Delirium is a neuropsychiatric disorder, triggered by medical precipitants causes. Study aims were to describe the prevalence and impact on in-hospital mortality of delirium identified through ICD-9 codes as well as evidence of neurocognitive deficits demonstrated in a population of older patients admitted to acute medical wards.

METHODS

This was a prospective cohort multicenter study of 2521 older patients enrolled in the "Registro Politerapie SIMI (REPOSI)" during the years 2010 and 2012. The diagnosis of delirium was obtained by ICD-9 codes. Cognitive function was evaluated with the Short Blessed Test (SBT) and single SBT items were used as measures of deficits in attention, orientation and memory. Combination of deficits in SBT items was used as a proxy for delirium. Logistic regression was used to evaluate the association with in-hospital mortality of delirium and combined deficits in SBT items.

RESULTS

Delirium was coded in 2.9%, while deficits in attention, orientation, and memory were found in 35.4%, 29.7% and 77.5% of patients. Inattention and either disorientation or memory deficits were found in 14.1%, while combination of the 3 deficits in 19.8%. Delirium, as per ICD-9 codes, was not a predictor of in-hospital mortality. In contrast, objective deficits of inattention, in combination with orientation and memory disorders, were stronger predictors after adjusting for covariates.

CONCLUSIONS

The documentation of delirium is poor in medical wards of Italian acute hospitals. Neurocognitive deficits on objective testing (in a pattern suggestive of undiagnosed delirium) should be used to raise awareness of delirium, given their association with in-hospital mortality.

Nailfold videocapillaroscopy in internal medicine

Capillaroscopy is an actual inexpensive imaging technique, used to examine, non-invasively and safely, the morphology of nailfold dermal papillary capillaries. Many studies agree in the statement that the capillaroscopy is one of the gold standard methods for non-invasive examination of the microcirculation and it plays an important role in screening in Raynaud’s phenomenon and in monitoring of systemic sclerosis and other rheumatologic diseases. There are also many reports on the possible use of nailfold capillaroscopy in the diagnosis and monitoring of many other diseases in internal medicine.

Clinical governance and internal medicine: a marriage of convenience?

Amplification in health expectations, increase in new technologies, decrease in economic resources and the breakdown of traditional control systems have led to the development of clinical governance (CG). The aim of the present pilot study was to investigate the application of CG tools in significant sample of Italian internal medicine wards (IMW). A 37-item questionnaire was developed and administered to 39 physicians, within 33 IMWs throughout Italy. Thanks to the data analysis, the perceived usefulness, the utilization rate of CG tools, the correlations between CG use, wards characteristics, and/or localization were studied. We identified at what organizational level the CG tools were applied and used. fifty-two percent of the studied tools were being used in the investigated hospitals. The average utility and utilization rate was different depending on the region of provenance. This research showed that CG is a methodology often used by Italian hospitals physicians, especially for inpatient care. The encouraging results of this pilot study could suggest opportunities to extend the survey at national level, to generalize the results.

High prevalence of fragility vertebral fractures in patients hospitalised in Internal Medicine Units. Results of the POINT (Prevalence of Osteoporosis in INTernal medicine) study

BACKGROUND

Osteoporotic vertebral fractures (VFs) often go unrecognised in both healthy individuals and in pathological conditions. Few data exist on VFs in patients hospitalised in Internal Medicine Units (IMUs), who often suffer from multiple concomitant chronic disorders.

AIM OF THE STUDY

This multicentre cross-sectional study was aimed at assessing the prevalence of VFs in an unselected population of patients referring to IMUs. Correlations between VFs and the main coexisting diseases were also investigated.

METHODS

Information on demographic, clinical and laboratory findings, and on the presence of known risk factors for osteoporosis was recorded. The Genant's semi-quantitative method was used to evaluate, in a central reading centre, the presence and severity of VFs in the thoracic and lumbar spine.

RESULTS

A cohort of 995 patients was evaluated. At least one VF of any grade was found in 47.5% of patients, with similar prevalence between females (48.1%) and males (46.7%). Older age, chronic obstructive pulmonary disease, and previous diagnosis of osteoporosis showed a significant association with VFs in multivariable analysis. However, 79.7% of the VFs were observed in patients without previous diagnosis of osteoporosis. Moreover, a VF of grade 2 or greater was found in 20.8% of patients.

CONCLUSIONS

Fragility VFs is a very frequent finding in patients hospitalised in IMUs. Consequently, more attention should be devoted in this clinical setting to this comorbidity, which is known to be an additional factor for mortality and, when localised in the thoracic part of the spine, may negatively influence a concomitant respiratory insufficiency.

Pain management in internal medicine and effects of a standardised educational intervention: the FADOI-DOMINO study

PURPOSE

Few real-world data are available on the frequency and management of pain in Internal Medicine (IM). Aims of our study were to assess the prevalence of pain in IM, and to evaluate the effects on pain management of a standardised educational programme.

MATERIALS AND METHODS

The study was performed in 26 IM Units in Italy, with two cross-sectional surveys (PRE phase and POST phase) interspersed with an educational programme. In PRE phase each Centre reviewed the hospital charts of the last 100 consecutive patients hospitalised for any cause. An educational programme was conducted in each Centre by means of the 'outreach visit', a face-to-face meeting between health personnel and a trained external expert. Six months after, each Centre repeated the data collection (POST phase), specular to the PRE.

RESULTS

A total of 5200 medical charts were analysed. Pain was documented in 37.5% of the patients. After the educational intervention, the intensity of pain was appropriately assessed in a higher percentage of patients (77.4% vs. 47.8%, p = 0.0001), and it was more frequently monitored during hospitalisation. Qualitative definition of pain (pathogenesis, duration, etc.) increased in POST phase (75.4% vs. 62.7%, p = 0.0001). A 73.3% increase in the use of strong opioids was detected following educational programme.

CONCLUSIONS

Pain affects 4 out of 10 patients hospitalised in IM. According to our large real-world study, to implement a standardised one-shot educational programme may persistently improve the attitude of health personnel towards the characterisation and management of pain.

Effectiveness of an educational intervention on the management of type 2 diabetic patients hospitalized in Internal Medicine: results from the FADOI-DIAMOND study

Appropriate management of hyperglycemia is crucial for patients with type 2 diabetes. Aim of the FADOI-DIAMOND study was to evaluate real-world management of type 2 diabetic patients hospitalized in Internal Medicine wards (IMW) and the effects of a standardized educational intervention for IMW staff. DIAMOND has been carried out in 53 Italian IMW, with two cross-sectional surveys interspersed with an educational program (PRE phase and POST phase). In PRE phase, each center reviewed the charts of the last 30 hospitalized patients with known type 2 diabetes. An educational program was conducted in each center by means of the "outreach visit," a face-to-face meeting between IMW staff and a trained external expert. Six months after, each center repeated the data collection (POST phase), specular to the PRE. A total of 3,167 patients were enrolled (1,588 PRE and 1,579 POST). From PRE phase to POST, patients with registered anthropometric data (54.1 vs. 74.9 %, p < 0.001) and in-hospital/recent measurement of glycated hemoglobin (48.2 vs. 61.4 %, p < 0.005) increased significantly. After educational program, more patients received insulin during hospitalization (68.3 vs. 63.6 %, p = 0.005). A more relevant variation in glycemia during hospitalization was observed in POST phase than PRE (-22.2 vs. -15.5 mg/dL, p < 0.001), without differences as for occurrence of hypoglycemia (12.3 vs. 11.9 %). A one-shot educational intervention led to persistent improvement in the management of hospitalized patients with type 2 diabetes and to significant better glycemic control. Further studies might evaluate the effectiveness of a more aggressive educational program, on both management and outcomes.

Evaluation of upper limb sense of position in healthy individuals and patients after stroke

The aims of this study were to develop and evaluate reliability of a quantitative assessment tool for upper limb sense of position on the horizontal plane. We evaluated 15 healthy individuals (controls) and 9 stroke patients. A robotic device passively moved one arm of the blindfolded participant who had to actively move his/her opposite hand to the mirror location in the workspace. Upper-limb's position was evaluated by a digital camera. The position of the passive hand was compared with the active hand's 'mirror' position. Performance metrics were then computed to measure the mean absolute errors, error variability, spatial contraction/expansion, and systematic shifts. No significant differences were observed between dominant and non-dominant active arms of controls. All performance parameters of the post-stroke group differed significantly from those of controls. This tool can provide a quantitative measure of upper limb sense of position, therefore allowing detection of changes due to rehabilitation.

Robot-aided neurorehabilitation in sub-acute and chronic stroke: does spontaneous recovery have a limited impact on outcome?

BACKGROUND

Robotic neurorehabilitation, thanks to high dosage/intensity training protocols, has the potential for a greater impact on impairment.

OBJECTIVE

We aimed to analyze how time since the acute event may influence the motor recovery process during robot-assisted rehabilitation of the upper limb.

METHODS

A total of 41 patients after stroke were enrolled: 20 in subacute phase, i.e. ≤ 6 months elapsed since their unilateral cerebrovascular accident (CVA), and 21 at chronic stage, i.e. > 6 months since CVA. All subjects underwent 30 minutes of robot-aided rehabilitation twice a day, 5 days a week for at least three weeks of training. Patients were evaluated at the start and end of treatment using the Fugl-Meyer and Modified Ashworth clinical scales and by a set of robot measured kinematic parameters. The time interval from stroke was considered as a grouping factor to analyze its impact on time course of recovery.

RESULTS

After training both groups significantly improved their impairment (F = 44.25, p < 0.001) but sub-acute patients showed a greater improvement on the Fugl-Meyer scale than chronic patients. The time course of recovery of the kinematic variables showed higher time constants of motor improvement in the sub-acute than chronic group, but they were one order lower than spontaneous recovery time constants.

CONCLUSIONS

Spontaneous recovery seems to have a limited impact on the improvement of sub-acute patients, most of their changes being likely due to re-learning during rehabilitation. In addition, a longer recovery time was required to maximize outcome in sub-acute than in chronic patients.

Identification and management of invasive mycoses in internal medicine: a road-map for physicians

Invasive mycoses are a rising problem, not only in traditional categories of patients like hematologic or neutropenic ones, but also in elderly non-neutropenic patients admitted to internal medicine wards. Patients being admitted to medical wards are usually older, have multiple comorbidities, e.g., liver cirrhosis or chronic obstructive respiratory disease, may be malnourished or receive peripheral or total parenteral nutrition, and frequently are undergoing chronic corticosteroid therapy, chemotherapy for cancer or monoclonal antibodies for autoimmune diseases. Such risk factors may be contemporarily present in a single patient increasing the risk for the development of invasive mycoses. Diagnosis of candidemia and invasive aspergillosis is particularly difficult in patients hospitalized on medical wards, since symptoms and signs have low specificity, and most diagnostic tests have been only validated in neutropenic hematologic patients, but not in those without neutropenia. Both candidemia and invasive aspergillosis carry significant morbidity and mortality. The aim of this paper is to provide a simple guide to physicians for a prompt identification and treatment of patients with possible or suspected invasive mycoses.

Thromboprophylaxis in acutely ill medical patients: results of a survey among Italian physicians

AIMS

acutely ill medical patients are at increased risk of venous thromboembolism (VTE) and often require thromboprophylaxis, but patient selection and adequate therapeutic decisions may be difficult due to the heterogeneity and the complexity of this population. We conducted a survey among a large cohort of Italian physicians to assess their approach to some important "grey" areas of VTE prevention in this setting.

METHODS

a questionnaire was distributed during the meeting of a national society of Internal Medicine (FADOI), held in May 2013. Four clinical scenarios describing areas of clinical uncertainty were administered to participants: the first on a patient with acute ischemic stroke; the second on a patient with severe renal insufficiency; the third on the duration of prophylaxis in the post-acute setting; and the last on a patient at high risk of VTE and at moderate risk of bleeding with preserved mobility.

RESULTS

453 questionnaires were returned (participants mean age 48.5 years). About 70% of participants systematically assess VTE and bleeding risk in their clinical practice, but a minority of them use risk assessment models. Prolonged prophylaxis in the post-acute setting was voted by more than eighty percent of participants; replies to the other three clinical scenarios were more heterogeneous with none of the options selected by more than 60% of participant.

CONCLUSION

physicians approach to "grey" areas of antithrombotic prophylaxis in the medical setting is quite heterogeneous and sometimes partially in contrast to recent guidelines, reinforcing the need for educational programs and high quality studies in this setting.

Effects of iloprost on pain-free walking distance and clinical outcome in patients with severe stage IIb peripheral arterial disease: the FADOI 2bPILOT Study

BACKGROUND

Patients with peripheral arterial disease (PAD) at stage IIb, pain-free walking distance (PFWD) less than 100 m and unsuitable for revascularization have both impaired quality of life and severe clinical outcome. Aim of the study was to evaluate the efficacy of the prostacyclin analogue iloprost, added to standard therapy, in these patients.

MATERIAL AND METHODS

Patients were randomized to receive standard medical therapy (Group A) or standard therapy plus iloprost (Group B), for 1 year. Iloprost was administered for 10 days every 3 months. Treadmill test was performed every 3 months, in Group B before starting the 10-day iloprost cycle.

RESULTS

Fifty patients in Group A and 51 in Group B were enrolled. Mean baseline and 12-month PFWD values were 75.4 ± 21.3 and 128.9 ± 62.9 for iloprost group and 70.3 ± 21.6 and 99.6 ± 62.6 m for controls. Patients treated with iloprost had significantly higher PFWD at 9 and 12 months. This finding was confirmed after carrying forward the last valid observation (124.7 ± 63.4 vs. 88.4 ± 63.1 m, P < 0.01). Major cardiovascular events occurred in 32.0% and 3.9% of patients in Group A and Group B, respectively (P < 0.001). Five patients in Group A died vs. none in Group B (P = 0.02). No serious unexpected adverse reactions occurred in patients receiving iloprost.

CONCLUSIONS

Iloprost, added to standard therapy, significantly increases exercise capacity in patients with PAD at severe stage IIb. The percentage of patients who died or experienced major cardiovascular events was significantly lower in patients receiving iloprost. Future studies should focus on the effects of this therapy on clinical outcome.

Complexity in hospital internal medicine departments: what are we talking about?

Internal medicine (IM) patients are mostly elderly, with multiple complex co-morbidities, usually chronic. The complexity of these patients involves the intricate entanglement of two or more systems (e.g. body and disease, family-socio-economic and environmental status, coordination of care and therapies) and this requires comprehensive, multi-dimensional assessment (MDA). Despite attempts to improve management of chronic conditions, and the availability of several MDA tools, defining the complex patient is still problematic. The complex profile of our patients can only be described through the best assessment tools designed to identify their characteristics. In order to do this, the Federation of Associations of Hospital Doctors on Internal Medicine FADOI has created its own vision of IM. This involves understanding the different needs of the patient, and analyzing diseases clusters and the possible relationships between them. By exploring the real complexity of our patients and selecting their real needs, we can exercise holistic, anthropological and appropriate choices for their treatment and care. A simpler assessment approach must be adopted for our complex patients, and alternative tools should be used to improve clinical evaluation and prognostic stratification in a hierarchical selection of priorities. Further investigation of complex patients admitted to IM wards is needed.
