Perceptions and Expectations of Youth Regarding the Respect for Their Rights in the Hospital

Information obtained from children themselves regarding the characteristics of the ideal hospital that ensure well-being during a hospital stay is scarce. Here, we report the opinions, perceptions, and expectations of 700 children and adolescents about their experiences, assessed through a mixed-method research approach with age-appropriate questionnaires, three open-ended questions, and an analysis of optional pictorial and textual narratives. Most children indicated that, while they acknowledged the expertise of hospital staff, they also noted several shortcomings, e.g., insufficiently understandable medical information as well as emotional and cognitive support. The continuity of schooling and the right to suffer as little as possible were also critical issues. Adolescents valued in particular the quality of care and services provided, the hospital's adherence to equality and non-discrimination rights, and protection systems but negatively perceived several aspects related to play and participation. Significant differences in the co-occurrences of the most frequently used text terms with the keywords "hospital" and "child/adolescent" between age groups highlight variations in the way patients perceive and articulate their experiences within the hospital setting depending on the cognitive processes linked to age. In drawings, prevailing attention was placed on the physical context of the hospital room, with figures expressing mostly negative emotions. Specifically, in this regard, the main emotion in children was sadness, and, in adolescents, it was fear. Overall, these insights are pivotal in the context of our research objectives as they shed light on the nuanced preferences, needs, and perspectives of children and adolescents during their hospital stays. Recognizing the identified shortcomings, we propose recommendations emphasizing the improvement of medical communication clarity, enhancement of emotional and cognitive support, and the improvement of programs to avoid instructional gaps during hospital stays. Addressing these specific needs is critical for a more comprehensive approach to pediatric healthcare provision.

The Communicative-Relational Operating Model of the Italian National Institute of Health for an Effective Telephone Intervention in Public Health, Structured on Basic Counselling Skills

Introduction

Communication has a crucial role in public health, because it becomes an essential component of prevention; it is also a proactive tool in health promotion. From a planning perspective, it is appropriate to use communication means that can help the bidirectional communication process, such as face-to-face communication and telephone communication.

Materials and methods

In relation to this, the Italian National Institute of Health has developed the "Modello Operativo Comunicativo-Relazionale" (the "Communicative-Relational Operating Model"). It is based on the fundamental skills of the counselling, this gives a protocol to the health professionals that is replicable and organized and it allows health professionals to carry out a telephone communication that is efficient with the user through technical-scientific and communication-relational skills. The goal is to answer in a customized way to the various users' health needs. The Operating Model was created by experts of the National AIDS and Sexually Transmitted Infections Helpline of the Operational Unit of Psycho-Socio-Behavioural Research, Communication, Training, of the Infectious Diseases Department. Later, the Operating Model was proposed to the experts of the Helplines in the National Centre on Addictions and Doping and the National Helpline of the National Centre for Rare Diseases in the National Institute of Health that integrated this method into their telephone approach.

Results

The Operating Model illustrated above was applied to several helplines of the National Institute of Health as an example of correct scientific information, updated and customized on sexual transmitted infections, addictions and rare diseases.

Conclusions

This article aims to illustrate the Operating Model, the theoretical prerequisites that subtend it and its possible application in the different public health structures that use the telephone for a profes-sional relationship with their users.

Multiple Sclerosis-Related Dietary and Nutritional Issues: An Updated Scoping Review with a Focus on Pediatrics

PURPOSE

Lifestyle/dietetic habits play an important role in the development and progression of multiple sclerosis (MS) disease. Here, we examine the basic pathomechanisms underlying intestinal and brain barrier modifications in MS and consider diets and dietary supplementations proposed over time to complement pharmacological therapies for improving disease outcome both in adults and in children.

METHODS

Scoping literature search about evidence-based findings in MS-related gut-brain axis (GBA) pathophysiology and nutritional issues at all ages.

FINDINGS

Data show that (1) no universal best diet exists, (2) healthy/balanced diets are, however, necessary to safeguard the adequate intake of all essential nutrients, (3) diets with high intakes of fruits, vegetables, whole grains, and lean proteins that limit processed foods, sugar, and saturated fat appear beneficial for their antioxidant and anti-inflammatory properties and their ability to shape a gut microbiota that respects the gut and brain barriers, (4) obesity may trigger MS onset and/or its less favorable course, especially in pediatric-onset MS. Vitamin D and polyunsaturated fatty acids are the most studied supplements for reducing MS-associated inflammation.

CONCLUSIONS

Pending results from other and/or newer approaches targeting the GBA (e.g., pre- and probiotics, engineered probiotics, fecal-microbiota transplantation), accurate counseling in choosing adequate diet and maintaining physical activity remains recommended for MS prevention and management both in adults and children.

Vitamin D Levels in the Pre- and Post-COVID-19 Pandemic Periods and Related Confinement at Pediatric Age

Coronavirus disease 2019 (COVID-19) restrictions have been correlated with vitamin D deficiency in children, but some uncertainties remain. We retrospectively studied vitamin 25-(OH) D blood levels in 2182 Italian children/adolescents hospitalized for various chronic diseases in the year before (n = 1052) and after (n = 1130) the nationwide lockdown. The type of underlying disease, gender, and mean age (91 ± 55 and 91 ± 61 months, respectively) of patients included in the two periods were comparable. Although mean levels were the same (p = 0.24), deficiency status affected a significantly higher number of subjects during the lockdown period than in the pre-COVID period (p = 0.03), particularly in summer (p = 0.02), and there was also a smoothing of seasonal variations in vitamin D levels. Particularly at risk were males (OR = 1.22; p = 0.03), the 1–5 year age group (OR = 1.57; p < 0.01) and the 6–12 year age group (OR = 1.30; p = 0.04). Infants appeared not to be affected (p = 1.00). In the post-COVID period, the risk of vitamin D deficiency was unchanged in disease-specific groups. However, the proportion of deficiency or severe deficiency differed significantly in the subgroup with endocrinopathy (higher; Chi-square p = 0.04), and with respiratory problems and obesity (lower; Chi-square p = 0.01 and p < 0.01, respectively). Conflicting/opposite literature results advocate for further studies to clearly indicate the need for supplementation during possible future periods of confinement.

Case Report: Add-on treatment with odevixibat in a new subtype of progressive familial intrahepatic cholestasis broadens the therapeutic horizon of genetic cholestasis

Odevixibat, an ileal bile acid transporter (IBAT) inhibitor, is effective for the treatment of pruritus in children diagnosed with progressive familial intrahepatic cholestasis (PFIC) type 1 and 2. There are no studies showing the efficacy of Odevixibat in children with different subtypes of PFIC. We describe the case of a 6-year-old girl with chronic cholestatic jaundice. In the last 12 months laboratory data showed high serum levels of bilirubin (total bilirubin x 2.5 ULN; direct bilirubin x 1.7 ULN) and bile acids (sBA x 70 ULN), elevated transaminases (x 3-4 ULN), and preserved synthetic liver function. Genetic testing showed homozygous mutation in ZFYVE19 gene, which is not included among the classic causative genes of PFIC and determined a new non-syndromic phenotype recently classified as PFIC9 (OMIM # 619849). Due to the persistent intensity of itching [score of 5 (very severe) at the Caregiver Global Impression of Severity (CaGIS)] and sleep disturbances not responsive to rifampicin and ursodeoxycholic acid (UDCA), Odevixibat treatment was started. After treatment with odevixibat we observed: (i) reduction in sBA from 458 to 71 μmol/L (absolute change from baseline: -387 μmol/L), (ii) reduction in CaGIS from 5 to 1, and (iii) resolution of sleep disturbances. The BMI z-score progressively increased from -0.98 to +0.56 after 3 months of treatment. No adverse drug events were recorded. Treatment with IBAT inhibitor was effective and safe in our patient suggesting that Odevixibat may be potentially considered for the treatment of cholestatic pruritus also in children with rare subtypes of PFIC. Further studies on a larger scale could lead to the increasing of patients eligible for this treatment.

Pediatric vs. adult NAFLD to MAFLD transition: a welcome but tangled path

The term non-alcoholic fatty liver disease (NAFLD) appears unfitting both in adults and in children. As obesity and metabolic syndrome play a relevant pathogenic role, an international group of adults’ liver disease experts has proposed to rename this condition metabolic (dysfunction)-associated fatty liver disease (MAFLD). While this new more appropriate and useful definition has mostly been met with good reactions in adults, it may present a tangled path in pediatrics. Here we further stress the recommendations of the North American and the European Societies for Pediatric Gastroenterology, Hepatology and Nutrition that a hyperechogenic liver in a child affected by obesity or overweight with chronically elevated liver enzymes should not be assumed to have NAFLD only. Especially in those patients who are not in the classic age range or who have particularly severe laboratory anomalies, other genetic, metabolic (inborn errors of metabolism, IEM), endocrine, intestinal and hepatic pediatric-onset conditions, should in fact be excluded, particularly when response to a weight loss trial is not available. The term pediatric fatty liver disease (PeFLD) with three subtypes (1. contextual diagnosis of an IEM; 2. Metabolic (dysfunction)-associated fatty liver; 3. unknown cause of fatty liver) has recently been proposed aiming to separate true MAFLD from IEM and/or the other above mentioned conditions, which may be rare when considered individually but represent a large group when considered collectively. Although the cost-effectiveness ratio of this attitude is still indeterminate, it is likely that the advantage of the early identification of a specifically treatable pediatric-onset liver disease associated to/mimicking MAFLD would be rewarding.

Malnutrition in Pediatric Chronic Cholestatic Disease: An Up-to-Date Overview

Despite recent advances, the causes of and effective therapies for pediatric chronic cholestatic diseases remain elusive, and many patients progress to liver failure and need liver transplantation. Malnutrition is a common complication in these patients and is a well-recognized, tremendous challenge for the clinician. We undertook a narrative review of both recent and relevant older literature, published during the last 20 years, for studies linking nutrition to pediatric chronic cholestasis. The collected data confirm that malnutrition and failure to thrive are associated with increased risks of morbidity and mortality, and they also affect the outcomes of liver transplantation, including long-term survival. Malnutrition in children with chronic liver disease is multifactorial and with multiple potential nutritional deficiencies. To improve life expectancy and the quality of life, patients require careful assessments and appropriate management of their nutritional statuses by multidisciplinary teams, which can identify and/or prevent specific deficiencies and initiate appropriate interventions. Solutions available for the clinical management of these children in general, as well as those directed to specific etiologies, are summarized. We particularly focus on fat-soluble vitamin deficiency and malnutrition due to fat malabsorption. Supplemental feeding, including medium-chain triglycerides, essential fatty acids, branched-chain amino acids, and the extra calories needed to overcome the consequences of anorexia and high energy requirements, is reviewed. Future studies should address the need for further improving commercially available and nutritionally complete infant milk formulae for the dietary management of this fragile category of patients. The aid of a specialist dietitian, educational training regarding nutritional guidelines for stakeholders, and improving family nutritional health literacy appear essential.

Emotional blunting and cognitive profile in elderly depressed patients in treatment with vortioxetine

Introduction

Antidepressants in older people have experienced their increase in medical prescriptions in recent decades whit comorbidity with other pathologies and drug polytherapies. With the use of antidepressants, can be observed side and unwanted effects (e.g. emotional blunting). Vortioxetine is a new antidepressant agent which promises fewer side effects.

Objectives

To evaluate the clinical efficacy, safety, side effects (e.g emotional blunting) and cognitive profile

Methods

45 elderly patients affected by MDD (DSM-5) were recruited in our observational study. All patients were treated with vortioxetine for 12 months. Physiological and pathological parameters were collected at baseline (T0), after 3 months (T1), 6 months (T2); 12 months (T3). All patients were administered the following scales: GDS; MMSE; QLi; ODQ. The statistical data were processed with EZAnalyze.

Results

33.33% of patients had a score in the “unlikely depression” GDS group. The ANOVA ODQ “Total” results indicate that at least two of the repeated measures differ significantly. Data of the “antidepressant as cause” dimension are interesting [T0 vs T3 (P-Unadjusted .000; P-Bonferroni .000; T-value 5.687. MMSE scores are indicative of one small but not significant difference. Mean QLIndex scores did not show statistically significant changes, but are indicative of positive changes from the baseline score

Conclusions

Vortioxetine resulted in partial reduction of depression. There was a moderate non-statistically significant increase in body weight, glycidic and lipid profiles. Overall data highlight the importance and role that vortioxetine can have in the management of depressive symptoms in elderly subjects. The handling, effectiveness and reduced side effects of the molecule are emphasized.

Noninvasive screening for congenital heart defects using a serum metabolomics approach

OBJECTIVE

Heart anomalies represent nearly one-third of all congenital anomalies. They are currently diagnosed using ultrasound. However, there is a strong need for a more accurate and less operator-dependent screening method. Here we report a metabolomics characterization of maternal serum in order to describe a metabolomic fingerprint representative of heart congenital anomalies.

METHODS

Metabolomic profiles were obtained from serum of 350 mothers (280 controls and 70 cases). Nine classification models were built and optimized. An ensemble model was built based on the results from the individual models.

RESULTS

The ensemble machine learning model correctly classified all cases and controls. Malonic, 3-hydroxybutyric and methyl glutaric acid, urea, androstenedione, fructose, tocopherol, leucine, and putrescine were determined as the most relevant metabolites in class separation.

CONCLUSION

The metabolomic signature of second trimester maternal serum from pregnancies affected by a fetal heart anomaly is quantifiably different from that of a normal pregnancy. Maternal serum metabolomics is a promising tool for the accurate and sensitive screening of such congenital defects. Moreover, the revelation of the associated metabolites and their respective biochemical pathways allows a better understanding of the overall pathophysiology of affected pregnancies.

Untargeted metabolomics as a diagnostic tool in NAFLD: discrimination of steatosis, steatohepatitis and cirrhosis

INTRODUCTION

Non-Alcoholic Fatty Liver Disease encompasses a spectrum of diseases ranging from simple steatosis to steatohepatitis (or NASH), up to cirrhosis and hepatocellular carcinoma (HCC). The challenge is to recognize the more severe and/or progressive pathology. A reliable non-invasive method does not exist. Untargeted metabolomics is a novel method to discover biomarkers and give insights on diseases pathophysiology.

OBJECTIVES

We applied metabolomics to understand if simple steatosis, steatohepatitis and cirrhosis in NAFLD patients have peculiar metabolites profiles that can differentiate them among each-others and from controls.

METHODS

Metabolomics signatures were obtained from 307 subjects from two separated enrollments. The first collected samples from 69 controls and 144 patients (78 steatosis, 23 NASH, 15 NASH-cirrhosis, 8 HCV-cirrhosis, 20 cryptogenic cirrhosis). The second, used as validation-set, enrolled 44 controls and 50 patients (34 steatosis, 10 NASH and 6 NASH-cirrhosis).The "Partial-Least-Square Discriminant-Analysis"(PLS-DA) was used to reveal class separation in metabolomics profiles between patients and controls and among each class of patients, and to reveal the metabolites contributing to class differentiation.

RESULTS

Several metabolites were selected as relevant, in particular:Glycocholic acid, Taurocholic acid, Phenylalanine, branched-chain amino-acids increased at the increase of the severity of the disease from steatosis to NASH, NASH-cirrhosis, while glutathione decreased (p < 0.001 for each). Moreover, an ensemble machine learning (EML) model was built (comprehending 10 different mathematical models) to verify diagnostic performance, showing an accuracy > 80% in NAFLD clinical stages prediction.

CONCLUSIONS

Metabolomics profiles of NAFLD patients could be a useful tool to non-invasively diagnose NAFLD and discriminate among the various stages of the disease, giving insights into its pathophysiology.

Multi-omics analysis reveals the influence of genetic and environmental risk factors on developing gut microbiota in infants at risk of celiac disease

BACKGROUND

Celiac disease (CD) is an autoimmune digestive disorder that occurs in genetically susceptible individuals in response to ingesting gluten, a protein found in wheat, rye, and barley. Research shows that genetic predisposition and exposure to gluten are necessary but not sufficient to trigger the development of CD. This suggests that exposure to other environmental stimuli early in life, e.g., cesarean section delivery and exposure to antibiotics or formula feeding, may also play a key role in CD pathogenesis through yet unknown mechanisms. Here, we use multi-omics analysis to investigate how genetic and early environmental risk factors alter the development of the gut microbiota in infants at risk of CD.

RESULTS

Toward this end, we selected 31 infants from a large-scale prospective birth cohort study of infants with a first-degree relative with CD. We then performed rigorous multivariate association, cross-sectional, and longitudinal analyses using metagenomic and metabolomic data collected at birth, 3 months and 6 months of age to explore the impact of genetic predisposition and environmental risk factors on the gut microbiota composition, function, and metabolome prior to the introduction of trigger (gluten). These analyses revealed several microbial species, functional pathways, and metabolites that are associated with each genetic and environmental risk factor or that are differentially abundant between environmentally exposed and non-exposed infants or between time points. Among our significant findings, we found that cesarean section delivery is associated with a decreased abundance of Bacteroides vulgatus and Bacteroides dorei and of folate biosynthesis pathway and with an increased abundance of hydroxyphenylacetic acid, alterations that are implicated in immune system dysfunction and inflammatory conditions. Additionally, longitudinal analysis revealed that, in infants not exposed to any environmental risk factor, the abundances of Bacteroides uniformis and of metabolite 3-3-hydroxyphenylproprionic acid increase over time, while those for lipoic acid and methane metabolism pathways decrease, patterns that are linked to beneficial immunomodulatory and anti-inflammatory effects.

CONCLUSIONS

Overall, our study provides unprecedented insights into major taxonomic and functional shifts in the developing gut microbiota of infants at risk of CD linking genetic and environmental risk factors to detrimental immunomodulatory and inflammatory effects. Video Abstract.

Serum metallome in pregnant women and the relationship with congenital malformations of the central nervous system: a case-control study

BACKGROUND

Congenital malformations of the central nervous system (CNS) consist of a wide range of birth defects of multifactorial origin.

METHODS

Concentrations of 44 metals were determined by Inductively Coupled Plasma Mass Spectrometry in serum of 111 mothers in the second trimester of pregnancy who carried a malformed fetus and compared them with serum concentrations of the same metals in 90 mothers with a normally developed fetus at the same week of pregnancy. Data are reported as means ± standard deviations.

RESULTS

We found a direct relationship between congenital defects of the CNS and maternal serum concentration of aluminum: it was statistically higher in women carrying a fetus with this class of malformation, compared both to mothers carrying a fetus with another class of malformation (6.45 ± 15.15 μg/L Vs 1.44 ± 4.21 μg/L, p < 0.0006) and to Controls (i.e. mothers carrying a normally-developed fetus) (6.45 ± 15.15 μg/L Vs 0.11 ± 0.51 μg/L, p < 0.0006). Moreover, Aluminum abundances were below the limit of detection in the majority of control samples.

CONCLUSION

CAluminum may play a role in the onset of central nervous system malformations, although the exact Aluminum species and related specific type of malformation needs further elucidation.

Metabolomics in genetic testing

Metabolomics is an intriguing field of study providing a new readout of the biochemical activities taking place at the moment of sampling within a subject's biofluid or tissue. Metabolite concentrations are influenced by several factors including disease, environment, drugs, diet and, importantly, genetics. Metabolomics signatures, which describe a subject's phenotype, are useful for disease diagnosis and prognosis, as well as for predicting and monitoring the effectiveness of treatments. Metabolomics is conventionally divided into targeted (i.e., the quantitative analysis of a predetermined group of metabolites) and untargeted studies (i.e., analysis of the complete set of small-molecule metabolites contained in a biofluid without a pre-imposed metabolites-selection). Both approaches have demonstrated high value in the investigation and understanding of several monogenic and multigenic conditions. Due to low costs per sample and relatively short analysis times, metabolomics can be a useful and robust complement to genetic sequencing.

Metabolomic Salivary Signature of Pediatric Obesity Related Liver Disease and Metabolic Syndrome

Pediatric obesity-related metabolic syndrome (MetS) and nonalcoholic fatty liver disease (NAFLD) are increasingly frequent conditions with a still-elusive diagnosis and low-efficacy treatment and monitoring options. In this study, we investigated the salivary metabolomic signature, which has been uncharacterized to date. In this pilot-nested case-control study over a transversal design, 41 subjects (23 obese patients and 18 normal weight (NW) healthy controls), characterized based on medical history, clinical, anthropometric, and laboratory data, were recruited. Liver involvement, defined according to ultrasonographic liver brightness, allowed for the allocation of the patients into four groups: obese with hepatic steatosis ([St+], n = 15) and without hepatic steatosis ([St–], n = 8), and with (n = 10) and without (n = 13) MetS. A partial least squares discriminant analysis (PLS-DA) model was devised to classify the patients’ classes based on their salivary metabolomic signature. Pediatric obesity and its related liver disease and metabolic syndrome appear to have distinct salivary metabolomic signatures. The difference is notable in metabolites involved in energy, amino and organic acid metabolism, as well as in intestinal bacteria metabolism, possibly reflecting diet, fatty acid synthase pathways, and the strict interaction between microbiota and intestinal mucins. This information expands the current understanding of NAFLD pathogenesis, potentially translating into better targeted monitoring and/or treatment strategies in the future.

Therapeutic faecal microbiota transplantation controls intestinal inflammation through IL10 secretion by immune cells

Alteration of the gut microbiota has been associated with different gastrointestinal disorders. Normobiosis restoration by faecal microbiota transplantation (FMT) is considered a promising therapeutic approach, even if the mechanisms underlying its efficacy are at present largely unknown. Here we sought to elucidate the functional effects of therapeutic FMT administration during experimental colitis on innate and adaptive immune responses in the intestinal mucosa. We show that therapeutic FMT reduces colonic inflammation and initiates the restoration of intestinal homeostasis through the simultaneous activation of different immune-mediated pathways, ultimately leading to IL-10 production by innate and adaptive immune cells, including CD4⁺ T cells, iNKT cells and Antigen Presenting Cells (APC), and reduces the ability of dendritic cells, monocytes and macrophages to present MHCII-dependent bacterial antigens to colonic T cells. These results demonstrate the capability of FMT to therapeutically control intestinal experimental colitis and poses FMT as a valuable therapeutic option in immune-related pathologies.

Placental tissue metabolome analysis by GC-MS: Oven-drying is a viable sample preparation method

Analysis of the human placenta metabolome has great potential to advance the understanding of complicated pregnancies and deleterious fetal outcomes in remote populations, but samples preparation can present unique challenges. Herein, we introduce oven-drying as a simple and widely available method of sample preparation that will facilitate investigations of the placental metabolome from remote and under-studied populations. Placentae from complicated and uncomplicated pregnancies were prepared in three ways (oven-dried at 60 °C, fresh, lyophilized) for metabolome analysis via gas chromatography-mass spectrometry (GC-MS). Multiple computer models (e.g. PLS-DA, ANN) were employed to classify and determine if there was a difference in placentae metabolome and a group of metabolites with high variable importance in projection scores across the three preparations and by complicated vs. control groups. The analyses used herein were shown to be thorough and sensitive. Indeed, significant differences were detected in metabolomes of complicated vs. uncomplicated pregnancies; however, there were no statistical differences in the metabolome of placentae prepared by oven-drying vs. lyophilization vs. fresh placentae. Oven-drying is a viable sample preparation method for placentae intended for use in metabolite analysis via GC-MS. These results open many possibilities for researching metabolome patterns associated with fetal outcomes in remote and resource-poor communities worldwide.

The tubercular disease in immigrants without documents: new diagnostic settings adopted in Milan, Italy

The tubercular disease (TB) is "the disease of poverty and people in need", spread in the poorest countries and among the less wealthy people of the western world (immigrants). In Italy the health authority has recently defined precise diagnostic and therapeutic patterns for TB. The social and health Association Naga in Milan with the Regional Reference Centre for TB, designed a screening system. In Naga's surgery all the undocumented immigrants, coming to Italy from countries with high TB incidence (> 100/100000) and high immigration rates, are screened by a questionnaire created by the Swiss Lung League; the suspect cases are sent to a designed centre for a second level of investigation. The use of this form allows to set a first selection based on the patients' anamnestic history, thus avoiding the intradermal reaction that, due to its low selectivity, could cause a 4 times higher crowding of the designed secondary centers.

Disease management of type 2 diabetes: a follow-up analysis in a sanitary district of Sicily

AIM

The aim of this paper was to analyze the Disease management of type 2 diabetes in a sanitary district of the Sicily Region (Italy).

METHODS

In a population of 9 698 subjects, we selected patients with known type 2 diabetes: a cohort of 385 subjects, (206 women and 179 men) following up for one year. Prevalence of type 2 diabetes in the analyzed population was 3.97%. A great lot of cohort was on a diet.

RESULTS

After one year, a per cent reduction of obese and overweight subjects was observed. No differences were observed for Body Mass Index (BMI) at the beginning and at the end of the study. After one year, through educational meetings with the doctor, a significant increase of knowledge on the patient's conditions and on the diabetes complications was verified, but our data showed persistent poor attention by doctors. The poor knowledge of patients led to a difficult disease management. After one year, a great lot of cohort used antistroke and cardiovascular disease therapy, reducing significantly the cardiovascular disease risk. However, our study also highlights a gap between the therapeutic guidelines and the actual treatment, with wide variability in the delivery of secondary prevention. CONCLUSION. Our study showed that a persevering warning and a constant adjournment of doctors improves the disease management, reducing complications risk in type 2 diabetes patients.

Capsule endoscopy of the small bowel in the clinical practice: outpatient management is feasible and cheaper

AIM

Four Italian regions have cost coding for outpatient capsule-endoscopy. Elsewhere it is performed in ordinary hospital admission. To identify, in a cohort of patients of a Gastroenterology Unit, those feasible for outpatient versus inpatient treatment; to analyze costs distribution in both management areas.

METHODS

We retrospectively analysed 100 clinical records of admissions to A.O. San-Carlo-Borromeo, Milan between 2005-2008. Hospitalization criteria (at least 3): 1) occult/obscure gastrointestinal bleeding; 2) hemoglobin ≤ 8 gr/dL; 3) indication for blood transfusions; 4) urgent hospital admission.

RESULTS

A total of 62 patients had urgent admission, 60 blood transfusions, 81 underwent EGD and colonoscopy, 8 enteroscopy and 5 surgery. Mean haemoglobin value was 8.67 g/dL. Capsule-endoscopy was positive in 70, uncertain in 8, negative in 22. Positive cases: 33 angiodyplasia, 18 ulcers/erosions, 13 polyps/masses, 5 overt bleeding, 1 celiac disease. 47/100 were appropriate as outpatient, saving 432 days of hospital stays. Admission coding was grouped into 7 DRGs (overall expense: 98,366 Euros). Considering EGD/colonoscopy outpatient costs and 1.100 euros as estimated value for capsule-endoscopy, the total expense could be 53.919.

CONCLUSION

Outpatient capsule-endoscopy small bowel examination is feasible in half of the cases. It is cost saving, (about 45.000 Euros/100 patients), reducing inappropriate hospital stays.

[Analysis of type 2 diabetes disease management: cross-study of a sanitary district]

AIM

We studied type 2 diabetes prevalence in the Sicilian country, and the disease management, trough the analysis of some indicators.

METHODS

A cohort of 385 subjects with type 2 diabetes was selected in a sanitary district. Anamnestic, anthropometric, pharmacological data were recorded by a self-controlled software (Gipac-2). We used Student's t-test for statistical data analysis.

RESULTS

The cohort of diabetic people represents 3.97% of the studied population in toto, 206 women and 179 men: only 2/3 of the studied people followed the therapeutic indications, using prevalently oral hypoglycemic therapy, with poor agreement to specialised centres for diabetes. Hypertension was present in 52.51% of men, in 68.21% of women; most of 50% of people, men and women, showed an obesity/overweight condition. The observations of eventual diabetes complications (eye, foot etc.) was poor by doctors: a 1/3 of patients had diabetes complications undefined. The disease management analysis showed the use of antiplatelet-adhesion drugs involved a half of the studied people; 55-60% of people agreed to diet restriction, no sex-related; the self-control of glucose blood value was present in 65-70% of subjects. The indicators analysis showed that only 40% of men and women performed a HbA1C measurement; 40-50% of people did not control blood pressure in 90 days, 65% did not perform a LDL measurement in one year, more than 70% did not perform a fundus oculi check up.

CONCLUSION

The study confirms the incidence of diabetes similar to national and European standards. The disease management appears lacunose in half of the population, the use of indicators is limited; guidelines on chronic disease management and on prevention of complications are partially applied. The use of sensitization strategies of sanitary operators, trough formation periods, is very important in order to implement the chronic disease management.

Elective surgery for benign liver tumours

BACKGROUND

Benign liver tumours (haemangioma, focal nodular hyperplasia, and hepatic adenoma) have different prevalence and prognosis. Spontaneous rupture and malignant transformation can complicate hepatic adenoma. Elective surgery is controversial, and indications are represented by uncertain diagnosis, presence of symptoms, and prevention of major complications.

OBJECTIVES

To assess the beneficial and harmful effects of elective surgery of benign liver tumours. We identified 31 cases series. These were small (with less than 60 participants) and the types of tumours mixed. These studies reported no significant mortality, but in the six studies with mortality it ranged from 1% to 17%.

SEARCH STRATEGY

The Cochrane Hepato-Biliary Group Controlled Trials Register and the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (searches in Issue 1, 2006), MEDLINE, EMBASE, CancerLit, and Science Citation Index Expanded (SCI-EXPANDED) (searched December 2005). A further search included the proceedings of major hepatological and surgical congresses (Annual Meetings of the American Association for the Study of the Liver (AASLD) and European Association for the Study of the Liver (EASL)), and examination of the references of relevant papers and reference lists of the identified studies.

SELECTION CRITERIA

Randomised clinical trials in adult patients with benign liver tumours without indications for emergency surgery in which elective surgery (resection) versus no intervention or sham operation are compared.

DATA COLLECTION AND ANALYSIS

All trials identified through searches were evaluated for eligibility for inclusion. We intended to extract relevant data in order to analyse the outcomes as per our published protocol using intention-to-treat analysis.

MAIN RESULTS

We could not identify any randomised clinical trials.

AUTHORS' CONCLUSIONS

We were unable to find evidence supporting or refuting elective surgery for patients with benign liver tumours. We need large, long-term randomised clinical trials with adequate methodology to assess the benefits and harms of elective surgery.

Gallbladder motility in obesity, diabetes mellitus and coeliac disease

We reviewed data on gallbladder motility in obesity, diabetes and coeliac disease. In obesity, a condition characterised by increased risk of gallstone(s), decreased gallbladder motility has heterogeneously been reported as a consequence of the different type of meals used to induce gallbladder contraction, characteristics of the population studied, technique used, and proportion of patients with hyperinsulinaemia. Moreover, recent studies have evaluated the effect of dietary restriction on gallbladder motility in obese patients. A two- to three-fold increase in the risk of cholesterol gallstone(s) has been reported in diabetic patients, mainly in relation to obesity and hypertriglyceridaemia. Furthermore, decreased gallbladder motility has been described and attributed to other factors, including underlying autonomic neuropathy, reduced gallbladder sensitivity to cholecystokinin and/or reduced number of cholecystokinin receptors on the gallbladder wall. Impaired gallbladder motility has been reported also in patients with coeliac disease in relation to reduced secretion of enteric hormones and/or decreased gallbladder sensitivity to them. In particular, untreated coeliacs, when compared to controls, showed low postprandial cholecystokinin and increased fasting somatostatin levels. Interestingly, the correlation between fasting somatostatin levels and gallbladder size has clearly been confirmed in patients affected by somatostatinoma or treated with somatostatin or its analogues. Gallbladder motility can be affected by various clinical conditions, such as obesity, diabetes mellitus and coeliac disease.

Clinical course of pregnant women with chronic hepatitis C virus infection and risk of mother-to-child hepatitis C virus transmission

As far as concerns chronic hepatitis C virus infection in pregnant women, different points remain to be elucidated, such as the clinical course, the rate of mother-to-child hepatitis C virus transmission and, in particular, its route and the possible risk factors. This review aimed to analyse current data on the prevalence of chronic hepatitis C virus infection in pregnant women and its relationship with risk factors, the rate of mother-to-child hepatitis C virus transmission and the factors possibly involved, particularly the maternal hepatitis C virus viral load and the human immunodeficiency virus coinfection, and the type of delivery and feeding. Finally, the appropriate timing for HCV-RNA testing in newborns has been reviewed.

Prevalence and clinical course of chronic hepatitis C virus (HCV) infection and rate of HCV vertical transmission in a cohort of 15,250 pregnant women

The prevalence and natural course of chronic hepatitis C virus (HCV) infection was evaluated in 15,250 consecutive pregnant women. The rate of HCV vertical and perinatal transmission was also assessed. The presence of anti-HCV was tested by means of EIA III and confirmed by recombinant immunoblot assay III. Alanine transaminase (ALT), anti-human immunodeficiency virus (HIV), and HCV-RNA were tested during the first month and third trimester of pregnancy, and 6 months after delivery; the same tests were made in all of the newborns of anti-HCV-positive mothers at birth (on cord blood samples) and then at 4-month intervals. Anti-HCV positivity was found in 370 cases (2.4%), 72% of whom were also HCV-RNA-positive. The proportion of women with hypertransaminases decreased from 56.4% at the first examination during the first month of pregnancy to 7.4% in the last trimester, and then increased again after delivery (54. 5%), without any concomitant changes in the proportion of those with viremia. The proportion of anti-HCV- and HCV-RNA-positive newborns was 5.1% after 1 year (8 of 155), all of whom had the same genotype as their mother. The rate of HCV transmission was not affected by the type of delivery or feeding, or the HIV status of the mother. The results of this large-scale study confirm previous data in smaller series concerning the prevalence of HCV infection in pregnant women, and strongly support the hypothesis of a favorable (possibly immunomediated) effect of pregnancy on liver cell necrosis in anti-HCV-positive women.

Immigration and health: the Italian National Focal Point experience

This report is a description of the situation of migrant populations in Italy. It was written by a committed team of experts from public institutions, non-governmental organisations (NGO) and volunteer associations that for three years have been part of the Italian National Focal Point (NFP) within the European Project "AIDS & Mobility", which is being co-ordinated by the Netherlands Institute for Health Promotion and Disease Prevention (the Netherlands) and financed by the European Commission DG/V. This year the Italian National Focal Point, co-ordinated by the Telefono Verde AIDS of the Istituto Superiore di Sanità, has produced a second report (the first one was published in 1998) on health issues related to migrant populations. Besides providing an updated picture on the presence of foreigners in Italy, such report illustrates the present legislative situation within the sanitary area and some interventions regarding prevention, treatment and rehabilitation provided by each structure in the Italian NFP to foreign citizens. The initiatives carried out during the year 1999 by public institutions, NGO and volunteer associations are also reported in order to detect the psycho-social-sanitary needs of immigrants and target prevention programmes to their particular and specific needs.

Severe hypopharyngeal dysphagia in a patient on chronic steroid treatment

A 44-year-old Caucasian male who had been on long-term steroid treatment for an unspecified collagen disease was referred to our Unit because of fever, severe hypopharyngeal dysphagia, night sweats and evidence of marked superior vena cava compression. Extrapulmonary disseminated tuberculosis also involving bone and liver was eventually diagnosed and proven by means of specific polymerase chain reaction assay. Antimycobacterial treatment, which led to a dramatic improvement within two months, was protracted for 18 months until the complete return to normal of both clinical and laboratory findings.

Immigration and health: the Italian situation. Italian National Focal Point (NFP) of the AIDS & Mobility Project

This report is a description of the situation of migrant populations in Italy. It was written as part of the European project "AIDS & Mobility", which is being co-ordinated by the Netherlands Institute for Health Promotion and Disease Prevention and financed by the European Union (EU). The report was written by the Italian National Focal Point (NFP) of the AIDS & Mobility Project, which consists of a committed team of experts from public institutions, non-governmental organizations, volunteer associations, and researchers from the Telefono Verde AIDS (National AIDS Help-line of Italy) of the Centro Operativo AIDS (COA, National AIDS Unit of Italy) of the Istituto Superiore di Sanità. The report illustrates the phenomenon of immigration in Italy, with demographic data (updated at 31 December 1997) on the presence of non-Italians and a review of the current laws pertinent to this phenomenon, with particular reference to health care laws. Moreover, epidemiological data on HIV/AIDS and on sexually transmitted diseases are provided, particularly as they relate to drug addiction and prostitution. Finally, following an accurate analysis of the situation and in light of the experience gained, the report includes proposals for identifying needs, objectives to pursue, and strategies to adopt, with respect to confronting the issue of immigration.

Value of a supervised exercise program for the therapy of arterial claudication

PURPOSE

This study was performed to test the effectiveness of a formal supervised exercise program against a home-based exercise program for both walking ability and quality of life endpoints.

METHODS

Patients with arterial claudication were randomized to either a 12-week supervised exercise program (SUPEX) with weekly lectures relating to peripheral vascular disease or to a home exercise group (HOMEX) who attended an identical lecture program and received weekly exercise instruction. The study population included 29 men and 26 women, with a mean age of 69.1 +/- 8.1 years. Forty-seven patients completed the 12-week program, 46 were available for testing at completion, and 38 for 6-month testing. Claudication pain time (CPT) and maximum walking time (MWT) on a progressive treadmill exercise test were assessed at baseline, program completion, and 6 months. The Medical Outcomes Study Short Form-36 (SF-36) was administered at these intervals to assess effects on quality of life.

RESULTS

Each group improved (p < 0.001) in both CPT and MWT at the completion of the 12-week program, which was sustained at the 6-month follow-up. Increase in HOMEX CPT from baseline (3.6 +/- 2.73 minutes) to 6-month follow-up (6.6 +/- 3.17 minutes) was less than for the SUPEX group (3.8 +/- 2.74 to 11.2 +/- 4.02 minutes, respectively); similar results were obtained for MWT. At both completion and 6 months, there was a significant intergroup difference for CPT and MWT (p < 0.004) favoring SUPEX. For both groups, measures of health perception based on the SF-36 demonstrated improvement (p < 0.002) in Physical Function Subscale, Bodily Pain Subscale, and Physical Composite Score. There were no between-group differences on the subsets of the SF-36 at the three assessment intervals.

CONCLUSIONS

Supervised exercise programs provide superior increased walking ability in the noninterventional therapy of arterial claudication, and both supervised and home based exercise therapy result in improved SF-36 functional measures. The lack of intergroup differences in these measures may be a result of the high degree of interaction with healthcare providers in the HOMEX group. Although a supervised program results in optimal walking benefits, a highly structured home-based program provides similar functional improvement and may be a satisfactory alternative for patients with lesser walking requirements.

Detection of rheumatoid factors of different isotypes and of circulating immune complexes in patients with inflammatory bowel disease

The behaviour of some serological aspects of autoimmunity was studied in patients with inflammatory bowel disease (IBD) by determining the incidence and levels of serum IgM, IgG and IgA rheumatoid factors (RF) and of circulating immune-complexes (IC) in 67 patients suffering from ulcerative colitis (UC) and 53 from Crohn's disease (CD). Sera from 40 young healthy subjects were included as controls. RF were detected by an enzyme linked immuno-assay (ELISA) and IC by the CIC-conglutinin and the CIC-C1q assays. ELISA detected a higher incidence of IgM RF in both UC and CD groups than the routine agglutination tests, although the mean levels were non significantly higher than in controls. Mean IgG RF levels were significantly above normal in UC and CD patients, the latter showing a greater incidence of elevated values and higher mean levels. IgA RF were significantly elevated only in CD patients; mean values for the UC group were within the normal range. The CIC-conglutinin test did not detect a significant incidence or high mean levels of IC and the CIC-C1q assay turned up a sizeable number of positive samples only in the CD group. Although still only preliminary, these overall findings suggest that RF activity is somehow present in patients with IBD. The greater prevalence of IC in CD patients, together with the patterns of IgG and IgA RF support the concept that this disease possibly involves autoimmune phenomena more than ulcerative colitis.

Analysis of human dysplastic haematopoiesis in long-term bone marrow culture

In this paper we have analysed the behaviour of myelodysplastic marrow in a long-term bone marrow liquid culture system (LTBMC) from eleven patients with myelodysplastic syndromes with regard to cellularity, day-7 and day-14 CFU-GM growth, cluster formation, adherent cells and CFU-F formation. An altered CFU-GM pattern was found in 64% of cases at diagnosis, while normal growth was seen in the remaining cases, all of which were affected by refractory anaemia. The levels of CFU-GM, as well as cellularity, were reduced in myelodysplastic marrows compared to normal controls over the whole duration of LTBMCs. Cases with a normal CFU-GM level at diagnosis also showed pathological behaviour when examined in LTBMC. The duration of dysplastic haematopoiesis was significantly shorter than that of controls. The proliferative ability of CFU-F was reduced in 50% of cases as shown by replating experiments. In conclusion, myelodysplastic marrow shows an abnormal behaviour in LTBMC, even in those cases which present normal CFU-GM growth at diagnosis.

Piperacillin plus amikacin versus cefotaxime plus amikacin in neutropenic and feverish patients with malignant hemopathies

Seventy-one neutropenic patients under cytostatic treatment for malignant hemopathies (neutrophil granulocytes less than or equal to/mm3 with feverish episodes in progress (T greater than or equal to 38.5 degrees C) which were probably of an infectious nature were treated according to two antibiotic protocols (piperacillin + amikacin [P + A] or cefotaxime + amikacin [C + A] in a randomized, comparative, prospective study. Of the 71 patients enrolled, 65 could in the end be evaluated for the purposes of this study (36 treated according to the P + A protocol, 29 according to the C + A protocol). In 16 patients the infection was documented bacteriologically. In these cases the percentages of response were, respectively, 77.7% with the P + A and 71.4% with the C + A protocol. The positive clinical results of the two protocols being studied were, considering the entire survey (bacteriologically documented, clinically documented and FUO infections), respectively, 69.4% in the patients treated with P + A and 62.0% in those treated with C + A. The results of the study seem to indicate that the severity of the neutropenia (N.G. less than 500 or greater than 500) does not affect the response to the antibiotic therapy. Modest and transient side effects (hypokalemia and increase of the ClCr) were noted above all in the patients subjected to the therapy with C + A. The results of this study show, therefore, a superimposable effectiveness of the two therapeutic protocols (P + A and C + A) in the empirical treatment of infections in neutropenic patients with malignant hemopathies.

Circulating immune complexes in serum and in cerebrospinal fluid of patients with multiple sclerosis. Characterization and correlation with the clinical course

We studied circulating immune complexes (IC) in the serum and cerebrospinal fluid (CSF) of patients with clinically defined multiple sclerosis (MS), in order to establish a correlation with the clinical course of the disease and to investigate the molecular composition of the IC isolated from patients in active phase of the disease. Serum IC levels were found to be significantly increased in patients from the progressive and active relapsing-remittent subgroups with both the CIC-conglutinin and C1q-binding methods. High levels of IC in CSF were detected only in the subgroup consisting of the relapsing-remittent patients in disease exacerbation when IC were determined by the C1q-binding test. No significant increase in serum or in CSF were found using the mRF-I test. The preliminary results of a qualitative investigation on serum IC in MS indicated that they are heterogeneous in nature, their size is mainly of the intermediate type, and they contain IgG, IgM, complement components and beta 2-microglobulins, the latter presenting an observation both new and interesting for studies on serum IC in MS patients.

ELISA determined IgM, IgG and IgA rheumatoid factors in rheumatoid arthritis and in other connective tissue diseases

We used an adaptation of an enzyme-linked immunoadsorbent assay (ELISA) to determine serum levels of IgM, IgG and IgA rheumatoid factors (RF) in 50 patients with classic or definite rheumatoid arthritis (RA) according to the ARA criteria, balanced for positive or negative-routine Latex-RF reaction. A control group of 50 young normal subjects and a reference group of 44 patients with other connective tissue diseases (OCTD) were also studied. We confirmed the high sensibility of the method, together with its good specificity and reproducibility. For the IgM RF a very significant correlation was found between ELISA results and Latex-RF titration (p less than 0.001). Many Latex-RF negative RA patients had high ELISA levels of IgM RF, suggesting that this assay reveals, at least in part, hidden or non-agglutinating IgM RF. Among the OCTD group only some SLE cases, mainly Latex-RF positive, had enhanced IgM RF on ELISA. Considered quantitatively, IgG RF did not play a significant diagnostic role for RA (p greater than 0.05), because they were also found, with widely dispersed values, in normal subjects, and because the mean increase in RA patients was relatively small. Interestingly, IgA RF were above the normal range in many RA patients, both Latex-RF positive or negative. The mean values differed significantly from those of controls (p less than 0.005), and a correlation was observed between IgA RF levels and IgA containing immune-complexes. Normal IgA RF values were observed in SLE patients, even if Latex-RF positive, suggesting that their increase in RA patients is not the mere expression of a polyclonal B cell activation.
