Abstract
Background: The disruption of social rhythms was found to be associated with depressive disorders during the COVID-19 pandemic; lower rates of these disorders were surprisingly found in old adults. The present study aims to verify the stability of social rhythms during lockdown in a sample of elderly people. Methods: Controlled cohort study (secondary analyses) of a previous randomized-controlled trial with the first evaluation in April 2019 (T0) and then 48 weeks later (T1) during the lockdown. The regulation of social and behavioral rhythms was measured through the Brief Social Rhythms Scale (BSRS); the Patient Health Questionnaire-9 (PHQ9) was adopted to detect relevant depressive symptoms. Results: 93 elderlies (73.36 ± 4.97 years old, 50.5% females) were evaluated at T0 and T1. Neither the total score of BSRS nor any of the 10 items showed a statistically significant difference comparing the two survey periods. The frequency of relevant depressive symptoms was 5.3% at T0 and 6.4% at T1 (OR = 0.8, CI95% 0.2-24). Conclusions: Among elderlies who did not show an increased risk of depression during the lockdown, social and behavioral rhythms remained exceptionally stable during the same period. Considering previous evidence about rhythms dysregulation preceding depression, their stability may be considered a factor of resilience.

Abstract
OBJECTIVES To explore the effects of anti-ribosomal P protein (anti-P) and anti-N-methyl-D-aspartic acid receptor subunit 2 (anti-NR2) autoantibodies on depression and cognitive dysfunction and their relationships with functional brain connectivity in SLE. METHODS This cross-sectional study included adult patients who fulfilled the American College of Rheumatology/European Alliance of Associations for Rheumatology 2019 SLE criteria. Anti-P and anti-NR2 were quantified using ELISA. A 1-hour battery of neuropsychological testing interpreted by a neuropsychologist explored depressive symptoms (Center for Epidemiologic Studies Depression Scale, CES-D), cognitive domains and quality of life (SF-12). Resting-state functional connectivity (rs-fc) MRI analysis was performed within 1 month, and region-of-interest to region-of-interest (ROI-to-ROI) analyses with the graph theory were performed. RESULTS Thirty-three patients with SLE (9% male) were enrolled, mean age (SD) of 43.5 (14) years and median disease duration of 10.4 years (2.9-25.4). Anti-P was positive in 6 (18.2%) and anti-NR2 in 14 (42.4%) patients. Depressive symptoms were found in 14 (42.4%) patients using the CES-D (range 0-51). After correction for age, disease duration, disease activity and white matter lesion load, the CES-D score was independently associated with anti-P serum level (β=0.32; p=0.049) and prednisone daily dose (β=0.38; p=0.023). Nineteen patients (57.6%) showed at least a cognitive test alteration, but no significant association with autoantibodies was found. The rs-fc MRI analysis revealed an independent association between the anti-P serum levels and many altered brain ROI properties but no anti-NR2 and prednisone effects on the cerebral network. CONCLUSIONS Anti-P was associated with brain network perturbation, which may be responsible for depressive symptoms in patients with SLE.

Abstract
Background: Cognitive impairment is a frequent consequence of bipolar disorder (BD) that is difficult to prevent and treat. In addition, the quality of the preliminary evidence on the treatment of BD through Cognitive Remediation (CR) with traditional methods is poor. This study aims to evaluate the feasibility of a CR intervention with fully immersive Virtual Reality (VR) as an additional treatment for BD and offers preliminary data on its efficacy. Methods: Feasibility randomized controlled cross-over clinical study, with experimental condition lasting three months, crossed between two groups. Experimental condition: CR fully immersive VR recovery-oriented program plus conventional care; Control condition: conventional care. The control group began the experimental condition after a three months period of conventional care (waiting list). After the randomization of 50 people with BD diagnosis, the final sample consists of 39 participants in the experimental condition and 25 in the control condition because of dropouts. Results: Acceptability and tolerability of the intervention were good. Compared to the waitlist group, the experimental group reported a significant improvement regarding cognitive functions (memory: p = 0.003; attention: p = 0.002, verbal fluency: p = 0.010, executive function: p = 0.003), depressive symptoms (p = 0.030), emotional awareness (p = 0.007) and biological rhythms (p = 0.029). Conclusions: The results are preliminary and cannot be considered exhaustive due to the small sample size. However, the evidence of efficacy, together with the good acceptability of the intervention, is of interest. These results suggest the need to conduct studies with larger samples that can confirm this data. Trial registration: ClinicalTrialsgov NCT05070065, registered in September 2021

Abstract
PURPOSE It is well known that interferon-α (IFN-α), used for long time as the main therapy for HCV-related disease, induces thyroid alterations, but the impact of the new direct-acting antivirals (DAAs) on thyroid is not established. Aim of this prospective study was to evaluate if DAAs therapy may induce thyroid alterations. METHODS A total of 113 HCV patients, subdivided at the time of the enrollment in naïve group (n = 64) and in IFN-α group (n = 49) previously treated with pegylated interferon-α and ribavirin, were evaluated for thyroid function and autoimmunity before and after 20-32 weeks of DAAs. RESULTS Before starting DAAs, a total of 8/113 (7.1%) patients showed Hashimoto's thyroiditis (HT) all belonging to IFN-α group (8/49, 16.3%), while no HT cases were found in the naïve group. Overall, 7/113 (6.2%) patients were hypothyroid: 3/64 (4.7%) belonging to naïve group and 4/49 (8.2%) to IFN-α group. Furthermore, a total of 8/113 patients (7.1%) showed subclinical hyperthyroidism: 2/64 (3.1%) were from naïve group and 6/49 (12.2%) from IFN-α group. Interestingly, after DAAs therapy, no new cases of HT, hypothyroidism and hyperthyroidism was found in all series, while 6/11 (54.5%) patients with non-autoimmune subclinical thyroid dysfunction became euthyroid. Finally, the only association between viral genotypes and thyroid alterations was genotype 1 and hypothyroidism. CONCLUSIONS This study supports evidence that DAAs have a limited or missing influence on thyroid in patients with HCV-related diseases. Moreover, it provides preliminary evidence that subclinical non-autoimmune thyroid dysfunction may improve after HCV infection resolution obtained by DAAs.

Abstract
BACKGROUND Cognitive Remediation (CR) programs are effective for the treatment of mental diseases; in recent years, Virtual Reality (VR) rehabilitation tools are increasingly used. This study aimed to systematically review and meta-analyze the published randomized controlled trials that used fully immersive VR tools for CR programs in psychiatric rehabilitation. We also wanted to map currently published CR/VR interventions, their methods components, and their evidence base, including the framework of the development intervention of CR in fully immersive VR. METHODS Level 1 of evidence. This study followed the PRISMA extension for Scoping Reviews and Systematic Review. Three electronic databases (Pubmed, Cochrane Library, Embase) were systematically searched, and studies were included if they met the eligibility criteria: only randomized clinical trials, only studies with fully immersive VR, and only CR for the adult population with mental disorders. RESULTS We found 4905 (database) plus 7 (manual/citation searching articles) eligible studies. According to inclusion criteria, 11 studies were finally reviewed. Of these, nine included patients with mild cognitive impairment, one with schizophrenia, and one with mild dementia. Most studies used an ecological scenario, with improvement across all cognitive domains. Although eight studies showed significant efficacy of CR/VR, the interventions' development was poorly described, and few details were given on the interventions' components. CONCLUSIONS Although CR/VR seems to be effective in clinical and feasibility outcomes, the interventions and their components are not clearly described. This limits the understanding of the effectiveness and undermines their real-world implementation and the establishment of a gold standard for fully immersive VR/CR.

Abstract
Introduction Cognitive deficits are considered a fundamental component of bipolar disorder due to the fact that they negatively impact personal/social functioning. Cognitive remediation interventions are effective in the treatment of various psychosocial disorders, including bipolar disorder. The use of Virtual reality as a rehabilitation tool has produced scientific evidence in recent years, especially in cardiovascular, neurological, and musculoskeletal rehabilitation. This study aims at evaluating the feasibility of a Cognitive Remediation Virtual Reality Program (CEREBRUM) for people with bipolar disorder in psychiatric rehabilitation. Material and Methods Feasibility randomized controlled cross-over clinical study; we randomized 50 people from the Consultation and Psychosomatic Psychiatry Center of the University Hospital of Cagliari (San Giovanni di Dio Civil Hospital) with a diagnosis of bipolar disorder. We propose a cognitive remediation program in virtual reality (CEREBRUM), 3 months with 2 weekly sessions, for the experimental group and a usual care program for the control group (psychiatric visit and/or psychotherapy). Results The results of the trial will be published in international peer-reviewed journals and will be disseminated at international meetings and congress. Discussion This RCT aims, with regards to its feasibility and design, to provide information about a confirmatory trial that evaluates the effectiveness of a Virtual Reality Cognitive Remediation program in psychiatric rehabilitation for the treatment of cognitive dysfunction in people with bipolar disorder. Conclusion The results that we analyzed at the end of the RCT will have an impact on psychiatric rehabilitation research with a focus on improving the application of technologies for mental health.Trial registration: ClinicalTrialsgov NCT05070065, registered on September 2021.

Abstract
Background: An important aspect of managing chronic disorders like bipolar disorder is to have access to relevant health information. This study investigates and compares the quality of information on the treatments of bipolar disorder that is available on English websites, as an international language, and on Italian websites, as a popular local language. Methods: A systematic review search was obtained from four search engines. We excluded unrelated materials, scientific papers, and duplicates. We analyzed popularity with PageRank; technological quality with Nibbler; readability with the Flesh Reading Ease test and Gulpease index; quality of information with the DISCERN scale, the JAMA benchmark criteria, and on the extent of adherence to the HONCode. Results: 35 English and 31 Italian websites were included. The English websites were found to have a higher level of quality information and technological quality than the Italian ones. Overall, the websites were found to be difficult to read, requiring a high level of education. Conclusions: These results can be important to inform guidelines for the improvement of health information and help users to reach a higher level of evidence on the websites. Users should find the benefits of treatment, support for shared decision-making, the sources used, the medical editor’s supervision, and the risk of postponing treatment.

Abstract
BackgroundCognitive dysfunction (CD) and mood disorders (MD) are among the most frequent neuropsychiatric (NP) events in Systemic Lupus Erythematosus (SLE), but their pathogenesis has not been clarified yet. Until now, an unquestionable correlation between the presence of specific autoantibodies, brain alterations and the presence of CDs and MDs in SLE is lacking.ObjectivesThe primary aim of the study was to explore the effects of anti-NR2 (anti-DWEYS) and anti-ribosomal-P (anti-P) antibodies on CDs and MDs and their relation with functional brain connectivity in patients affected by SLE.MethodsA cross-sectional study was conducted, between April 2019 and February 2020, including adult patients who fulfilled the ACR/EULAR 2019 SLE criteria.Demographics, ongoing medications, SLEDAI and SLICC/Damage Index were recorded. Serum level quantification for anti-P (normal values <18 U/ml) and anti-NR2 (normal values <0.5 OD) antibodies were performed using an ELISA. A battery of neuropsychological testing was interpreted by a neuropsychologist, exploring cognitive domains, depression and quality of life. A resting-state functional connectivity (rs-fc) MRI analysis was performed within 2 weeks since the neuropsychological status assessments. Two region of interest to region of interest (ROI-to-ROI) analyses with the graph theory was performed.ResultsThirty-three SLE patients (9% male) were enrolled, mean age 43.5 (+-14) years, and median disease duration of 10.4 years (IQR 2.9-25.4) (Table 1). Anti-P were positive (range 0-255 U/ml) in 6 patients (18.2%) and anti-DWEYS (range 0-1.8 OD) in 14 (42.4%). Nineteen out of 33 patients (57.6%) showed at least a cognitive test alteration, but no significant association with antibodies was found. Depression was found in 14 (42.4%) patients using the Center for Epidemiologic Studies Depression Scale (CES-D) as screening instrument. In multiple regression backward models, after correction for age, disease duration, SLEDAI and SDI, the CES-D showed an independent association with anti-P titre (β= 0.32 per U/ml; p=0.049) and prednisone daily dose (β=0.38 per mg/day; p=0.023). The rs-fc MRI analysis revealed a statistically significant association between the titre of anti-P and many altered properties of the brain ROIs (Figure 1), but no effects of PDN daily dose on specific cerebral networks.Table 1.Demographic and clinical characteristics of the patients in total, Legend: PDN: Prednisone; LLDAS: Lupus Low Disease Activity State; OD: Optical densityDemographic and clinical characteristics of the participants(N=33)Age, years mean (DS)43.5 (14.0)Gender (M, %)3 (9%)Disease duration, months median (IQR)124.4 (34.7-305)SLEDAI-2k mediane (IQR)4 (0-14)Dose PDN mg/daily median (IQR)6.4 (3.8-13.5)LLDAS N, %12 (36,4%)SLICC-DI mediane (IQR)0 (0-1)Ongoing treatment25 (75.8%)Hydroxychloroquine30 (90.9%)Immunosuppressive9 (27.3%)BiologicsEducation less than 8 years13 (39.4%)Anti-Rib-P N, %6 (18.2%)Anti-Rib-P (U/ml) mean (DS)10.9 (5.7-13.3)Anti-DWEYS N, %14 (42.4%)Anti-DWEYS (OD) mean (DS)0.4 (0.25-0.67)Anti-phospholipids N, %11 (33.3%)anti-dsDNA N, %18 (54.5%)anti-dsDNA Titre mediane (IQR)22.5 (2.9-74.5)Figure 1.Results of rs-fc MR Analysis 1 (effects of Anti-rib-P titre) on cerebral networks.

Abstract
Background: This study aimed to evaluate the respect for users’ rights, job satisfaction, and well-being between mental health workers (MHWs) compared to non-mental health care workers (nMHWs) from the same Italian region. Methods: The sample was recruited from community mental health and non-mental health outpatient centers in Sardinia. Participants fulfilled the WellBeing at work and respect for human-rights questionnaire (WWRR). The sample included 240 MHWs and 154 nMHWs. Results: MHWs were more satisfied with their work and workplace compared to nMHWs. MHWs had stronger beliefs that users were satisfied with the care received, and both workers and users’ human rights were respected in their workplace. MHWs reported to need more rehabilitation therapists and psychologists in their services, while nMHWs needed more nurses and professionals for users’ personal care. Italian MHWs are more satisfied with their work and workplace, and more convinced that users are satisfied with the care received and that users’ and staff human rights are respected in their workplaces, compared to nMHWs. Conclusions: The historic link between the community mental health network and other support networks in Italy and the consequent perception of proximity to the citizens of the care network may be the reason for this optimal situation of Italian MHWs.

Abstract
BACKGROUND The Internet is increasingly used as a source of information. This study investigates with a multidimensional methodology the quality of information of websites dedicated to obesity treatment and weight-loss interventions. We compared websites in English, a language that it is used for the international scientific divulgation, and in Italian, a popular local language. METHODS Level of Evidence: Level I, systematic review search on four largely used search engines. Duplicated and unrelated websites were excluded. We checked: popularity with PageRank; technological quality with Nibbler; readability with the Flesch Reading Ease test or the Gulpease readability index; quality of information with the DISCERN scale, the JAMA benchmark criteria, and the adherence to the Health on the Net Code. RESULTS 63 Italian websites and 41 English websites were evaluated. English websites invested more in the technological quality especially for the marketing, experience of the user, and mobile accessibility. Both the Italian and English websites were of poor quality and readability. CONCLUSIONS These results can inform guidelines for the improvement of health information and help Internet users to achieve a higher level of information. Users must find benefits of treatment, support to the shared decision-making, the sources used, the medical editor's supervision, and the risk of postponing the treatment.

Abstract
INTRODUCTION Italy is one of the high-income countries hit hardest by Covid-19. During the first months of the pandemic, Italian healthcare workers were praised by media and the public for their efforts to face the emergency, although with limited knowledge and resources. However, healthcare workers soon had to face new challenges at a time when the national health system was working hard to recover. This study focuses on this difficult period to assess the impact of the COVID-19 pandemic on the mental health of Italian healthcare workers. MATERIALS AND METHODS Healthcare workers from all Italian regions [n = 5,502] completed an online questionnaire during the reopening phase after the first wave lockdown. We assessed a set of individual-level factors (e.g., stigma and violence against HCWs) and a set of workplace-level factors (e.g., trust in the workplace capacity to handle COVID-19) that were especially relevant in this context. The primary outcomes assessed were score ≥15 on the Patient Health Questionnaire-9 and score ≥4 on the General Health Questionnaire-12, indicators of clinically significant depressive symptoms and psychological distress, respectively. Logistic regression analyses were performed on depressive symptoms and psychological distress for each individual- and workplace-level factor adjusting for gender, age, and profession. RESULTS Clinically significant depressive symptoms were observed in 7.5% and psychological distress in 37.9% of HCWs. 30.5% of healthcare workers reported having felt stigmatized or discriminated, while 5.7% reported having experienced violence. Feeling stigmatized or discriminated and experiencing violence due to being a healthcare worker were strongly associated with clinically significant depressive symptoms [OR 2.98, 95%CI 2.36-3.77 and OR 4.72 95%CI 3.41-6.54] and psychological distress [OR 2.30, 95%CI 2.01-2.64 and OR 2.85 95%CI 2.16-3.75]. Numerous workplace-level factors, e.g., trust in the workplace capacity to handle COVID-19 [OR 2.43, 95%CI 1.92-3.07] and close contact with a co-worker who died of COVID-19 [OR 2.05, 95%CI 1.56-2.70] were also associated with clinically significant depressive symptoms. Similar results were found for psychological distress. CONCLUSIONS Our study emphasizes the need to address discrimination and violence against healthcare professionals and improve healthcare work environments to strengthen the national health system's capacity to manage future emergencies.

Abstract
Background: Restrictions during Covid-19 pandemic lockdown, in which rhythms of life have been compromised, can influence the course of bipolar disorder (BD). This study follows patients with bipolar disorder living in two geographically close cities (Cagliari and Tunis), but with different lockdown conditions: less severe in Tunis. Methods: Two cohorts were evaluated during lockdown (April 2020, t0) and 2 months later with lockdown lifted for a month (t1). Individuals were: over 18 years old without gender exclusion, BD I or II, in care for at least 1 year, received a clinical interview in the month before the start of the lockdown, stable clinically before the lockdown. The assessment was conducted by telephone by a psychiatrist or psychologist with good knowledge of patients. Diagnoses were made according to DSM-5 criteria. Depressive symptoms were collected through the Hamilton Rating Scale for Depression; cut-off 14 indicative of depressive episode. Circadian rhythms were measured using the BRIAN scale. Results: Forty individuals in Cagliari (70%female, age 48.57 ± 11.64) and 30 in Tunis (53.3% Female, age 41.8 ± 13.22) were recruited. In Cagliari at t0 45% had depressive episodes against none in Tunis, a similar difference appeared at t1. At t0 and t1 the Cagliari sample had more dysfunctional scores in the overall BRIAN scale and in the areas of sleep, activities and social rhythms; no differences were found in nutrition, both samples had predominantly nocturnal rhythm. In Cagliari at t0 and t1, the depressive sub-group showed more dysfunctional scores in the BRIAN areas sleep, activity, and nutrition. However, the differences in biological rhythms resulted, through ANCOVA analysis, independent of the co-presence of depressive symptoms. Discussion: A rigid lockdown could expose people with BD to depressive relapse through dysregulation of biological rhythms. The return to more functional rhythms did not appear 1 month after lockdown. The rekindling of the pandemic and the restoration of new restrictive measures will prevent, at least in the short term, the beneficial effect of a return to normality of the two cohorts. This was a limited exploratory study; future studies with larger samples and longer observational time are needed to verify the hypothesis.

Abstract
BACKGROUND The perception by mental health service staff of respect for users' rights is a fundamental component of organizational well-being. The objective of this work is to examine how cultural differences and the working context can influence the perception of respect for users' rights in mental health professionals in the Mediterranean area. METHODS An observational survey carried out in four different mental health networks in four countries of the Mediterranean area (Tunisia, North-Macedonia, Italy, Palestine). Each invited participant fulfilled a format on socio-demographic information and coded the Well-Being at Work and Respect Right Questionnaire (WWRR). All data were encrypted and analysed using the Statistical Package for Social Sciences (SPSS) version 20. The Games-Howell post-hoc test was used to assess differences between countries. The Games-Howell test does not assume equal variances and sample sizes. Eta-squared (η2) was used as a measure of effect size in the ANOVA (η2 around 0.01, 0.06, and 0.14 are considered small, medium, and large, respectively). RESULTS The sample included 590 professionals working in the mental health field. The four countries showed statistically significant differences with regards to the quality rights assessment tool. Participants from Italy reported, on average, the highest scores across the questions. There were also differences across the countries about the perception of the impact of available resources on the effectiveness of care (η2 = 0.106). CONCLUSION Our findings offer a useful insight into the perception of the quality of mental health services, especially from a users' rights point of view.

Abstract
INTRODUCTION The overuse of antibiotics is causing worldwide spread of antimicrobial resistance (AMR). Compared with other countries, Italy has both high antibiotic consumption rates and high rates of AMR. Due to the fact that around 90% of antibiotics are prescribed by general practitioners (GPs), this study aims to measure the impact of knowledge, attitudes and sociodemographic and workplace-related factors on the quality of antibiotic prescriptions filled by GPs in the Italian Region of Sardinia. METHODS AND ANALYSIS Knowledge, attitude, sociodemographic and workplace-related factors deemed to influence physicians prescribing behaviour will be evaluated in a cross-sectional study conducted among all GPs of the Italian Region of Sardinia (n=1200). A knowledge and attitudes questionnaire (Knowledge and Attitudes on Antibiotics and Resistance - Italian version: ITA-KAAR) accompanied by a sociodemographic form will be linked to drug prescription data reimbursed by the National Health System. European Surveillance of Antibiotic Consumption quality indicators for outpatient antibiotic use will be calculated from drug prescription records. Every GP will be deemed to have demonstrated an adequate quality of prescriptions of antibiotics if half of the indicator score plus one is better than the median of the region. A multivariate Poisson regression model with robust variance estimation will be used to evaluate the impact of the determinants of antibiotic prescriptions on the actual prescribing quality of each physician. ETHICS AND DISSEMINATION The project has been approved by the ethics committee of the Regional Health Trust of Sardinia (176/2019/CE, 24 September 2019). The results will be useful to inform evidence-based interventions to tackle irrational antibiotic use in the community.

Abstract
OBJECTIVE In the last decades, immediate breast reconstruction (IBR) raised in frequency, and prepectoral positioning of the implant is becoming the trend nowadays. The aim of this paper is to describe our case series in IBR with prepectoral implant placement and complete coverage of it with the TiLoop® Bra titanium-coated polypropylene mesh (TCPM), pre-shaped as a pocket. PATIENTS AND METHODS Eighteen women with breast tumors were selected and underwent mono- or bilateral mastectomies and prepectoral IBR with tissue expanders or prostheses. After the prepectoral lodge was ready, the implants were inserted into TiLoop® Bra Pocket meshes and positioned over the pectoralis major muscle fascia. The mean surgical time of their positioning was four minutes. RESULTS This preliminary study showed meaningful results in prepectoral IBR with TiLoop® Bra Pocket covering the implants, for we observed a reduction of implant's exposure time and risk of bacterial contamination. Of the 18 patients that underwent this procedure, only three presented complications that resolved in a maximum of four weeks. CONCLUSIONS A considering reduction of surgical time in implant positioning was achieved, lowering exposure time and risk of complications as infection.

Abstract
OBJECTIVE The main goal of oncoplastic breast surgery (OBS) is to optimize cosmetic outcomes and reduce patient morbidity, while still providing an oncologically-safe surgical outcome and extending the target population of conservative surgery. Although the growing number of reported experiences with oncoplastic surgery, few studies account for the long-term outcomes. PATIENTS AND METHODS Between January 2000 and December 2010, 1024 consecutive oncoplastic surgeries were performed and prospectively included in a database. Demographic data, histological and oncological evaluation and surgical complications were recorded. The role of tumor and patients' characteristics on the development of local recurrence and metastases were assessed by multivariate analysis. RESULTS Median follow up was 74.2 months. The average age of patients was 56.24. In 869 patients (84.9%) an invasive tumor and in 155 (15.1%) an in situ tumor (11% DCIS and 4% LIN) was found. The average size of the tumor was 24.5 mm. A positive margin presented in 67 (6.5%) patients. Forty patients (50%) underwent re-excision and 39 (49.4%) underwent mastectomy. The overall breast conservation rate was 96.2%. Reported complications were: 17 wound infections (1.7%); 106 hematomas (10.4%); 94 lymphorrheas (9.2%), 48 partial wound dehiscence (4.7%). Local recurrences (LR) were observed in 49 patients (4.7%). The risk of local recurrence was significantly higher in the group of patients with lymphovascular invasion and with high grade (G) (p < 0.05). 52 (5.07%) distant metastases were reported and the related risk was significantly higher in the group of patients with lymphovascular invasion and with negative receptors (p < 0.05). CONCLUSIONS Oncoplastic surgery provides an acceptable oncological long-term outcome and can be used to treat with conservative surgery also a selected population of patients who would had otherwise undergone mastectomy in the past.

Abstract
BACKGROUND The use of bibliometric analysis to assess scientific productivity and impact is particularly relevant for EU funding programs. The objective of the present study is to assess the impact on scientific literature by focusing specifically on the cost-effectiveness of FP7 and NHI projects in the fields of AA and QoL, respectively. METHODS Twenty projects were randomly selected from the CORDIS database in accordance with the following criteria: funded by the FP7; accepted from 1st January 2007 to 31st December 2012; concluded by 31st August 2017;For each project selected, we determined: number of publications in Scopus and Google databases attributable to the project; number of papers published in Q1 quartile of the SCIMAGO rank; number of citations found in Scopus and Scholar Google; amount of funds allocated. RESULTS The study has confirmed the results of the previous one, namely that the number of publications and the number of citations per project on active ageing are similar in projects funded by the NHI in the United States and those funded by the FP7 in Europe. However, when it comes to cost-effectiveness, it results that European projects have a cost ten times higher than the Americans ones. CONCLUSION Our study shows lower cost-effectiveness of FP7-European projects than the American-NIH on active aging. The results of this research, albeit with the limits already outlined, will have to be taken into consideration in the evaluative research of the future.

Abstract
Background: The objective of this research is to verify whether European projects on Active Aging (AA) and Elderly Quality of Life (Qol) funded by the Seventh Framework Programme (FP7) produce an impact on literature similar to projects funded by the National Health Institute (NHI) of the United States on international literature using well-known bibliometric indicators. This effort may be useful in developing standardized and replicable procedures. Methods: Fifteen randomly selected projects on AA and Elderly Qol concluded in August 2017 and funded by FP7 were compared to similar projects funded by the US NHI with reference to papers published (Scopus and Scholar), papers published in Q1 journals, and the number of citations of the papers linked to the projects. Results: In all the indicators considered, the European projects showed no difference with the US NHI projects. Conclusions: The EU-funded AA and Qol Elderly projects have an impact on scientific literature comparable to projects funded in the United States by the NHI Agency. Our results are consistent with the data on general medical research, which indicates that, European research remains at a high level of competitiveness. In this experimental study, our methodology appeared to be convincing and reliable and it could be applied to the extent of the impact of more extensive research areas. Our research did not evaluate the relationship between funding required by research and scientific productivity.

Abstract
BACKGROUND Research literature suggests that burnout, depression, and a low mental quality of life (QOL) are common among health care workers. Economic crisis might have increased the burden of burnout, depression and low QOL in health care workers. OBJECTIVES To identify depression risk, burnout levels, and quality of life in a sample of workers of an Italian university hospital. METHOD Cross sectional study with comparison with two community surveys database results (n = 2000 and 1500, respectively). Overall, 522 workers accepted to take part in the study, representing a 78% response rate (out of 669 individuals). RESULTS The frequency of positivity at the screener for Major Depressive Disorder among health care workers was more than double than that in the standardized community sample (33.3% vs 14.1%, p<0.0001). All professionals, except the administrative staff and technicians (i.e. those who do not have contact with patients), showed a statistically higher frequency of positivity for depressive episodes compared to the controls. Among the medical staff, the highest risk was found in the surgeon units, while the lowest one was in the laboratories. Surgeons also were those most exposed to high risk of burnout, as measured by the Maslach Burnout Inventory. CONCLUSION Since burnout is linked to patient safety and quality of patient care, and contribute to medical errors, dedicated interventions aimed at reducing poor mental health and low quality of life in medical staff are indicated.

Abstract
Objective: To ascertain lifetime prevalence of positivity to a screening questionnaire for bipolar disorders (BD) in Sardinian immigrants to Argentina and residents of Sardinia and assess whether such positivity affects quality of life (QoL) in either group. Our hypothesis is that screen positivity for BD may be more frequent in immigrants. Methods: Observational study. Subjects were randomly selected from the membership lists of associations of Sardinian immigrants in Argentina. A study carried out in Sardinia using the same methodology was used for comparison. The Mood Disorder Questionnaire was used to screen for mania/hypomania and the Short-Form Health Survey-12 to measure QoL. Results: A higher prevalence of manic/hypomanic episodes was found in Sardinian immigrants to Argentina (p < 0.0001; odds ratio = 3.0, 95% confidence interval 1.87-4.77). Positivity at screening was associated with a lower QoL both in Sardinian immigrants to Argentina and in residents of Sardinia. Conclusions: To the best of our knowledge, this is the first study to show a higher lifetime prevalence of manic/hypomanic episodes in a general-population sample of individuals who migrated to a foreign country. Our results are in agreement with the hypothesis that hyperactive/novelty-seeking features may represent an adaptive substrate in certain conditions of social change.

Abstract
BACKGROUND / OBJECTIVES The aim of the study was to compare the Quality of Life (QoL) of Sardinian immigrants to Argentina with Sardinians residing in Sardinia. The hypothesis was that a different availability of effective treatments for mood disorders may impact the well being of persons with these disorders. METHODS One out of five families of Sardinian origin was randomly selected. An Italian study (including Sardinia) was adopted as the control. The Mood Disorder Questionnaire was used for screening mania/hypomania; the diagnosis of Current Major Depressive Disorder was conducted by means of the Patient Health Questionnaire in immigrants and by means of a clinical interview in the control study and in an immigrant subsample (to verify comparability); the Short-Form Health Survey-12 was applied to measure QoL. RESULTS The Sardinian immigrants showed a higher QoL than Italians in Italy (but not with Sardinians residing in Sardinia). On the contrary, the attributable burden worsening QoL due to lifetime manic/hypomanic episodes, as well as to current depressive episodes, was found higher among Sardinian immigrants with respect to both Sardinian residents in Sardinia and the total Italian sample. The use of effective treatment for mood disorder was higher in Italy. CONCLUSION The study found that in a sample of Sardinian immigrants in Buenos Aires the impact of a mood disorder affects QoL more incisively than in Sardinians residing in Sardinia. The suggested hypothesis of a possible role of beliefs guiding the search for treatments will be verified in future studies.

Abstract
BACKGROUND The aim of this study is to measure in two samples of Sardinian immigrants in Buenos Aires and representatives of the population in Sardinia the prevalence of depressive symptoms at the time of an economic crisis in Sardinia and to compare these results with those collected at the time of a similar crisis in Argentina more than 10 years before. METHODS Observational study. The associations of Sardinian immigrants in Buenos Aires provided the lists of families of Sardinian origin. A random sample of one fifth of registered families was selected. The sample of a study carried out in Sardinia was used as the control. The results were compared with those of the previous study performed in 2001-2002. The Patient Health Questionnaire (PHQ9) was used for the screening of depression. RESULTS The Sardinian immigrants show a lower rate of scoring positively on PHQ9 (i.e. less risk of being depressed) and reach statistical significance after standardization (8.7% vs. 13.1%, P = 0.046). Young women (≤40) are at higher risk. On the contrary, the risk of depression was higher in Sardinian immigrants in Argentina during the 2001-2002 crises. CONCLUSION The study indicates a risk for depressive episodes linked to the fallout of the economic crisis (in Argentina in 2001-2002, in Sardinia in 2015) and specifically more in females than in males. Due to the associated socio-demographic risk factors, these results could be interpreted as due to an increase in non-bipolar depression.

Abstract
Among lifestyle factors, nutrition is one of the most important determinants of health, and represents a pivotal element of cancer risk. Nonetheless, epidemiological evidences of the relationship between several cancers and specific foods and nutrients is still inadequate, and solid conclusions are missing. Indeed, caloric restriction without malnutrition is associated to cancer prevention. Food may be also the primary route of exposure to contaminants such as metals, persistent organic pollutants, and pesticides. Exposuredisease associations and the interplay with genetic susceptibility requires further studies on genetic variation, environment, lifestyle, and chronic disease in order to eliminate and reduce associated health risks, thus contributing to improve health outcomes for the population. A primary nutritional approach for Active and Healthy Ageing (AHA) has been developed by the Nutrition group of the European Innovation Partnership (EIP) on AHA. The working group on lifestyles of the Italian Ministry of Health has developed a comprehensive approach to adequate nutrition using a consensus methodology to collect and integrate the available evidences from the literature and from the Italian experiences at the regional level, to raise the interest of other experts and relevant stakeholders to outline and scale-up joint strategies for a primary nutritional approach to cancer prevention.

Abstract
MicroRNAs (miRNAs) have an important role in a wide range of physiological and pathological processes, and their dysregulation has been reported to affect the development and progression of cancers, including hepatocellular carcinoma (HCC). However, in the plethora of dysregulated miRNAs, it is largely unknown which of them have a causative role in the hepatocarcinogenic process. In the present study, we first aimed to determine changes in the expression profile of miRNAs in human HCCs and to compare them with liver tumors generated in a rat model of chemically induced HCC. We found that members of the miR-100 family (miR-100, miR-99a) were downregulated in human HCCs; a similar downregulation was also observed in rat HCCs. Their reduction was paralleled by an increased expression of polo like kinase 1 (PLK1), a target of these miRNAs. The introduction of miR-100 in HCC cells impaired their growth ability and their capability to form colonies in soft agar. Next, we aimed at investigating, in the same animal model, if dysregulation of miR-100 and PLK1 is an early or late event along the multistep process of hepatocarcinogenesis. The obtained results showed that miR-100 downregulation (i) is already evident in very early preneoplastic lesions generated 9 weeks after carcinogenic treatment; (ii) is also observed in adenomas and early HCCs; and (iii) is not simply a marker of proliferating hepatocytes. To our knowledge, this is the first work unveiling the role of a miRNA family along HCC progression.

Abstract
To estimate the prevalence of childhood overweight and obesity among Italian schoolchildren and to examine geographic differences and present and future implications for health care, we used data from a nationwide representative survey performed in May 2008 among third-grade students in 18 of Italy's 21 regions. Cluster sampling was used to identify classes for participation. The study population included all children aged 8-9 years whose parents agreed to opt-out consent. Parents, children and teachers completed brief questionnaires, and children were weighed and measured by trained staff using standardized equipment. Consent was obtained for 97% of 50 197 third-graders, of whom 44 676 (89%) met study inclusion criteria. Obesity levels (defined using International Obesity Task Force cut-offs) ranged from 7.5% (95% confidence intervals 6.7-8.2) in the north to 16.6% (95% confidence intervals 15.8-17.4) in the south. Behaviours known to be associated with obesity also showed geographic differences. The estimated burden of obesity-related pathologies also increased from north to south. These findings suggest the need for community as well as individual interventions in all areas of the country but with particular attention to the south.

Abstract
From 1994 to 2009, national field epidemiology training programmes (FETP) have been installed in Spain, Germany, Italy, France and Norway. During their two year duration, different components of the FETP are devised as follows: 63-79 weeks are spent on projects in hosting institutes, 2-26 weeks in outside projects, 9-30 weeks in courses and modules, and 1-2 weeks in scientific conferences. A considerable proportion of the Spanish FETP has is provided conventional class room training . The content of the modules is very similar for all programmes. Except from the Italian programme, all focus on infectious disease epidemiology. The German and Norwegian programmes are so called EPIET-associated programmesas their participants are integrated in the modules and the supervision offered by EPIET, but salaries, facilitators, and training sites are provided by the national programme. These EPIET-associated programmes require strong communications skills in English. Alumni of all five FETP are generally working within the public health work force in their respective countries or at international level, many of them in leading functions. Although three new FETP have been installed since the last published Euroroundup in Eurosurveillance on European FETP in 2001, the progress with respect to the establishment of national FETP or EPIET-associated programmes has been slow. Member States should be aware of how much support EPIET can offer for the establishment of national FETP or EPIET-associated programmes. However, they also need to be ready to provide the necessary resources, the administrative environment and long-term dedication to make field epidemiology training work.

Abstract
During the months of May and June 2007 two prevalence studies were conducted in two local health units in Italy (Terni and Bari). The objectives of the studies were to test methods and procedures to be used in the nutritional surveillance in primary schools; to measure the prevalence of obesity and overweight in children from those schools; and to determine the prevalence of physical activity and sedentary behaviour A total of 1026 children were measured and interviewed. The refusal rate was 17% in Terni and 16% in Bari. In Terni 8% of children were obese, 24% overweight, while in Bari the corresponding values were 11% and 24%. A high prevalence of behavioural risk factors for obesity was registered such as: not eating breakfast, reduced physical activity and sedentary behaviour It was also demonstrated that parents are often unaware that their children were overweight. The results of these surveys were consistent with the high prevalence that has been registered in other studies on Italian children in the third grade. The results showed also the feasibility of surveys in schools on the nutritional situation of children in primary schools, that can be adopted as a tool for a national surveillance.

Abstract
OBJECTIVES Liver regeneration is attenuated in old age and is substantially slower after 90% than after 70% partial hepatectomy (PH). We have previously demonstrated that the proliferative response to a primary mitogen is intact in aged mice, indicating that impaired liver regeneration is not due to loss of proliferative capacity. Here, we have investigated whether mitogenic effects of triiodothyronine (T3) could reverse the impaired regeneration of ageing or 90% hepatectomy, in the rat. MATERIALS AND METHODS T3 (20 microg/100 g body weight) was administered to 14-month-old rats subjected to 70% PH or to young rats subjected to 90% PH. Cell-proliferative capacity was determined by bromodeoxyuridine incorporation and microscopy and changes of cell cycle-related proteins were analysed by Western blot analysis. RESULTS Treatment of old intact rats with T3 increased cyclin D(1) expression that was followed by an enhanced proliferative response, the labelling index (LI), being 7.8% versus 1.3% of controls. T3 given before 70% PH stimulated regenerative response (LI was 10.8% versus 2.28%), and expression of cyclin D(1) and proliferating cell nuclear antigen (PCNA) 24 h after PH. Pre-treatment with T3 also improved the regenerative response of the liver after 90% hepatectomy (LI was 27.9% versus 14.2%). CONCLUSIONS These findings show in principle that mitogen-induced hyperplasia could be applied to human therapy in patients with reduced regenerative capacity or massive loss of hepatocytes.

Abstract
CONTEXT Italy implemented a law in January 2005 banning smoking in all enclosed public spaces. OBJECTIVES To document perceived obstacles and effects of the law and observed client smoking behaviours in bars and restaurants. DESIGN Four surveys were conducted between December 2004 and February 2006. Protocols and questionnaires were posted on a public health website to solicit participation among local health units (LHUs). Participating LHUs randomly selected 50 bars and restaurants using the electronic Yellow Pages. Self-administered questionnaires were delivered to owners or managers of selected locales; all of them were revisited during peak hours to collect questionnaires and observe client smoking. RESULTS Before the ban, smokers were observed in 31% of locales; 24% of owners predicted major financial losses. One year later, no smokers were observed and only 7% reported major financial losses. Only 30% had received law enforcement visits. Most owners/managers (88%) reported positive attitudes about the law and 79% reported such attitudes among clients. CONCLUSIONS The Italian smoking law has drastically reduced smoking in bars and restaurants despite minimal enforcement visits. Perceived negative effects on profits appear limited, and the owners and managers and their clients are satisfied.

Abstract
We present here findings obtained on a large number of human tissues over a period of more than ten years, by our modification of the Osmium maceration method for high resolution scanning electron microscopy (HRSEM). Data are documented by original pictures which illustrate both some 3-D intracellular features not previously shown in human tissues, and results obtained in our current studies on mitochondrial morphology and on the secretory process of salivary glands. We have demonstrated that mitochondria of cells of practically all human tissues and organs have usually tubular cristae, and that even the cristae that look lamellar are joined to the inner mitochondrial membrane by tubular connexions similar to the crista junctions later seen by electron tomography. Concerning salivary glands an important result is the development of a morphometric method that allows the quantitative evaluation of the secretory events.

Abstract
Since the mid-1990s, hepatitis C virus (HCV) transmission through blood transfusion has become very rare in western countries. Better understanding of the current modes of transmission is needed. However, risk factors have been mainly estimated on prevalent HCV infections. In this paper we describe the methods of the main case-control studies and their contribution to the knowledge on modes of HCV transmission. We also report the results of a case-control study of incident HCV infections recently carried out in France which confirms the continuing major role of IV drug use and suggests that transmission related to invasive care remained a potential source of new HCV infection between 1995 and 2001.

Abstract
In addition to the economic consequences and threats associated with outbreaks, listeriosis remains of great public health concern, as it has one of the highest case fatality rates of all the foodborne infections (20%-30%), and has common source epidemic potential. Changes in the way food is produced, distributed and stored have created the potential for diffuse and widespread outbreaks involving many countries. In 2002, a survey was carried out to assess the need for and the feasibility of a European network on listeria infections in humans. Data on surveillance systems and laboratory methods were collected through two postal surveys sent to the national Centres for communicable disease surveillance and to the listeria reference laboratories. Surveillance systems for listeria infections were in operation in 16 out of the 17 countries surveyed, and 16 countries had a national reference laboratory (NRL). All countries based their case definition of listeriosis on the isolation of Listeria monocytogenes. Fourteen NRLs performed at least one typing method on human strains. At least 13 countries already carried out or expressed willingness to carry out characterisation of isolates by pulsed field gel electrophoresis (PFGE) of L. monocytogenes strains isolated from human cases following a standard protocol. The participants concluded that there was a clear added value to having a European surveillance network for listeria infections, particularly for outbreak detection and investigation, and that a surveillance network based on the existing national surveillance systems was feasible.

Abstract
Thyroid hormone is known to elicit diverse cellular and metabolic effects in various organs, including mitogenesis in the rat liver. In the present study, experiments were carried out to determine whether thyroid hormone is able to stimulate cell proliferation in another quiescent organ such as the pancreas. 3,5,3'-L-tri-iodothyronine (T3) added to the diet at a concentration of 4 mg/kg caused a striking increase in nuclear bromodeoxyuridine (BrdU) incorporation of rat acinar cells 7 days after treatment (the labeling index was 46.7% in T3-treated rats vs 7.1% in controls). BrdU incorporation was limited to the acinar cells, with duct cells and islet cells being essentially negative. The increase in DNA synthesis was accompanied by the presence of several mitotic figures. Histological examination of the pancreas did not exhibit any sign of T3-induced toxicity. Determination of the apoptotic index, measurement of the serum levels of alpha-amylase and lipase, and glycemia determination did not show any increase over control values, suggesting that the enhanced proliferation of acinar cells was a direct effect induced by T3 and not a regenerative response consequent to acinar or beta-cell injury. Additional experiments showed that DNA synthesis was induced as early as 2 days after T3 treatment (the labeling index was 9.4 vs 1.9% in controls) and was associated with increased protein levels of cyclin D1, cyclin A and proliferating cell nuclear antigen, with no substantial differences in the expression of the cyclin-dependent kinase inhibitor p27. The mitogenic effect of T3 on the pancreas was not limited to the rat, since extensive acinar cell proliferation was also observed in the pancreas of mice treated with T3 for 1 week (the labeling index was 28% in T3-treated mice vs 1.8% in controls). Treatment with three other ligands of nuclear receptors, ciprofibrate, all-trans retinoic acid and 1,4-bis[2-(3,5-dichloropyridyloxy)]benzene, induced little or no pancreatic cell proliferation. These results demonstrated that T3 is a powerful inducer of cell proliferation in the pancreas and suggested that pancreatic acinar cell proliferation by selected agents may have potential for therapeutic use.

Abstract
Retinoids have been shown to exert an anticarcinogenic effect through suppression of the cell cycle, induction of apoptosis and/or differentiation. In rat liver, in particular, retinoic acid has been shown to inhibit regeneration after partial hepatectomy, most probably through repression of the expression of c-fos and c-jun. Surprisingly enough, in spite of the proposed therapeutic effects of all-trans retinoic acid (tRA) no data are available on its effect on normal adult liver. Here, we show that tRA administration in the diet (150 mg/kg) increased DNA synthesis in mouse liver, at 1 and 2 weeks, with a return to control values at 4 weeks (labelling index was 16.5, 8.3 and 3.3%, respectively, versus control values of 1.4, 1.3 and 2.5%). Increase in mitotic index paralleled that of bromodeoxyuridine incorporation. Kinetic studies showed that entry into S phase began between 24 and 48 h, with a peak between 96 and 120 h. Histological observation of the liver and biochemical evaluation of the levels of serum glutamate-pyruvate transaminases did not reveal any evidence of cell death demonstrating that increased DNA synthesis was not due to tRA-induced liver damage and regeneration, but rather the consequence of a direct mitogenic effect. In addition, analysis of total hepatic DNA content after a 7-day treatment showed a significant increase in tRA-fed mice compared with controls (21.11 mg/100 g body wt in tRA-fed mice versus 15.67 mg/100 g body wt of controls). Hepatocyte proliferation in tRA-fed mice was associated with increased hepatic levels of cyclin D1, E and A, and enhanced expression of the member of pRb family, p107. In conclusion, the results showed that tRA induces hepatocyte proliferation in the absence of cell death, similarly to other ligands of steroid/thyroid hormone nuclear receptor superfamily. The mitogenic effect of tRA cautions about its possible use for antitumoral purposes in liver carcinogenesis.

Abstract
Five clustered cases of leptospirosis were diagnosed in the area of Rochefort, France, in June 2001, among teenagers who had swum in the Genouillé canal. The symptoms included fever, headache, abdominal pain and vomiting, chills and myalgia. Three cases were confirmed by PCR and serology. The mean cumulative duration of bathing was significantly higher in cases (23.8 hours) compared to controls (14.4 hours). No other particular risk factor was observed. The environmental investigation revealed the presence of rodents excreting of leptospires near the bathing area. For all antigens considered, the occurence of seropositive rodents was 30.8%, L. icterohaemorrhagiae being the predominant serogroup (23,1%).

Abstract
Studies on hepatocyte primary cultures have suggested that loss of expression of the placental form of glutathione S-transferase in peroxisome proliferator (PP)-induced hepatocarcinogenesis is due to inhibition of glutathione S-transferase P (GSTP) transcription by the PPs. In the present study, we have analyzed the effect of a PP, ciprofibrate, and of another ligand of nuclear receptors, 3,3', 5-triiodo-L-thyronine (T3), on GSTP mRNA and protein levels in an in vivo model where GSTP expression was induced in Wistar rats by pre-treatment with a single dose of lead nitrate. Results indicate that administration of ciprofibrate or T3, immediately after lead nitrate treatment, did not exert any inhibitory effect on GSTP mRNA and protein levels, as revealed by both Western and immunohistochemical analysis. The results indicate that PPs do not inhibit hepatocyte GSTP expression induced in vivo by lead nitrate and suggest that inhibition of GSTP expression by PPs may not necessarily be the cause for the rapid disappearance of GSTP-positive preneoplastic lesions observed after a short term exposure to these agents.

Abstract
Previous studies have demonstrated that short-term treatment with peroxisome proliferators decreased the size and number of gamma-glutamyl transpeptidase or placental glutathione S-transferase (GSTP)-positive hepatic hyperplastic lesions. In this study, we have examined the effect of the hormone triiodothyronine (T3), which, similarly to peroxisome proliferators, is a strong liver mitogen and a ligand of nuclear receptors, on the growth of GSTP-positive nodules generated by the resistant hepatocyte model and on the development of hepatocellular carcinoma. Hepatic hyperplastic nodules were induced in male Fischer rats by a single dose (150 mg/kg) of diethylnitrosamine, followed by a 2-week exposure of the animals to 2-acetylaminofluorene and partial hepatectomy. Nine weeks after diethylnitrosamine administration, rats were switched to a diet containing 4 mg/kg T3 for 1 week (experiment 1) and sacrificed during T3 feeding or were exposed to seven cycles of T3-supplemented diet (1 week/month per 7 months), and sacrificed 6 months after the last cycle (experiment 2). Results showed that T3 treatment for 1 week caused a 70% reduction in the number of GSTP-positive nodules (14/cm2 in T3-fed rats versus 44/cm2 of control animals), as well as GSTP-positive area (12% versus 43% of controls). Reduction in the number of GSTP-positive nodules observed 1 week after T3 feeding was associated with a strong increase in the labeling index of enzyme-altered nodules compared with that of controls (labeling index was 64 and 31%, respectively). No significant differences in the apoptotic index were observed between the two groups. Results from experiment 2 did reveal that although rats treated with diethylnitrosamine + 2-acetylaminofluorene developed 100% hepatocellular carcinoma and 33% of them showed lung metastasis, only 50% of rats exposed to repeated cycles of triiodothyronine developed hepatocellular carcinoma with no lung metastasis. This study indicates that cell proliferation per se might not necessarily represent a promoting condition for putative preneoplastic lesions and demonstrates an anticarcinogenic effect of T3.

Abstract
We have previously demonstrated that hepatocyte proliferation induced by the mitogen 1,4-bis[2-(3,5-dichloropyridyloxy)] benzene (TCPOBOP) is independent of changes in cytokines, immediate early genes, and transcription factors that are considered to be necessary for regeneration of the liver after partial hepatectomy (PH) or necrosis. To further investigate the differences between mitogen-induced mouse hepatocyte proliferation and liver regeneration after PH, we have measured the expression of cyclin D1, cyclin D3, cyclin E, and cyclin A and of the cyclin-dependent kinases CDK2, CDK4, and CDK6. The involvement of the cyclin-dependent kinase inhibitors p21 and p27 and of the oncosuppressor gene p53 was also examined at different times after stimulation of hepatocyte proliferation. Results showed that a single administration of TCPOBOP caused a very rapid increase in the levels of cyclin D1, a G1 protein, when compared with two thirds PH (8 hours versus 30 hours). The early increase in cyclin D1 protein levels was associated with a faster onset of increased expression of S-phase-associated cyclin A (24 hours versus 36 hours with PH mice). Accordingly, measurement of bromodeoxyuridine (BrdU) incorporation revealed that, although approximately 8% of hepatocytes were BrdU-positive as early as 24 hours after TCPOBOP, no significant changes in BrdU incorporation were observed at the same time point after two thirds PH. The expression of other proteins involved in cell cycle control, such as cyclin-dependent kinases (CDK4, CDK2, CDK6), was also analyzed. Results showed that expression of CDK2 was induced much more rapidly in TCPOBOP-treated mice (2 hours) than in mice subjected to PH (36 hours). A different pattern of expression in the two models of hepatocyte proliferation, although less dramatic, was also observed for CDK4 and CDK6. Expression of the CDK inhibitors p21 and p27 and the oncosuppressor gene p53 variably increased after two thirds PH, whereas basically no change in protein levels was found in TCPOBOP-treated mice. The results demonstrate that profound differences in many cell cycle-regulatory proteins exist between direct hyperplasia and compensatory regeneration. Cyclin D1 induction is one of the earlier events in hepatocyte proliferation induced by the primary mitogen TCPOBOP and suggests that a direct effect of the mitogen on this cyclin may be responsible for the rapid onset of DNA synthesis observed in TCPOBOP-induced hyperplasia.

Abstract
Previous studies have suggested that liver cell proliferation is fundamental for the growth of carcinogen-initiated cells. To gain further information on the association between cell proliferation and hepatocarcinogenesis, we have examined the effect of the hormone 3,3',5-triiodo-L-thyronine (T3), a strong liver mitogen, on the growth of diethylnitrosamine (DENA)-induced hepatic lesions positive for the placental form of glutathione S-transferase (GSTP). Two weeks after a single initiating dose of DENA (150 mg/kg), cycles of liver cell proliferation were induced in male Fischer rats by feeding a T3-supplemented diet (4 mg/kg) 1 week/month for 7 months. Rats were killed at the end of the seventh cycle or 1 month later. Results indicate that, in spite of an increased labelling index, a 70% reduction in the number/cm(2) of GSTP-positive minifoci occurred in T3-treated rats. A decrease in the number of GSTP-positive foci was also observed in T3-treated rats killed 1 month after the last exposure to the hormone (40, versus 67 foci/cm(2) in controls), indicating that the reduction was not due to an inhibitory effect on GSTP exerted by the concomitant presence of T3. In a second series of experiments where DENA-treated rats were fed T3 for 1 week and then subjected to the resistant hepatocyte (RH) model, it was found that T3 treatment prior to promotion resulted in a decrease in the number of GSTP-positive foci (16 GSTP(+) foci/cm(2) in T3-fed animals versus 45 in the control group). The results indicate that cell proliferation associated with T3 treatment: (i) reduces the number of carcinogen-induced GSTP-positive lesions; (ii) does not exert any differential effect on the growth of the remaining foci; (iii) inhibits the capacity of putative DENA-initiated cells to be promoted by the RH model. Data suggest that cell proliferation may not necessarily represent a stimulus for the growth of putative preneoplastic lesions.

Abstract
OBJECTIVE There is still controversy about the efficacy and cost-effectiveness of outreach nutrition rehabilitation centres (NRCs) for severely malnourished children. We wanted to compare the mortality rates and nutritional status of severely malnourished children admitted to rural NRCs in Gabu region, Guinea Bissau, with other severely malnourished children who were not rehabilitated and stayed in their villages. DESIGN Retrospective cohort study over a 3-year period. Mortality rates and nutritional outcome compared for children who were admitted to rural NRCs and those who were not rehabilitated. Selection for admission to the NRCs was based on availability of places only. SETTING 19 health areas of the Gabu region, Guinea Bissau, West Africa. SUBJECTS 1038 severely malnourished children (< 60% weight-for-age using NCHS standards) aged 6 to 47 months. 354 were rehabilitated in NRCs and 684 received no rehabilitation. RESULTS Up to 36 months follow-up the relative risk of death in the rehabilitated group was 0.75 [95% confidence interval (c.i.) = 0.57-0.99], equivalent to a 25% reduction in mortality. The difference in mortality between the two groups was much higher during the first 3 months [P < 0.02, relative risk = 0.59 (95% c.i. = 0.39-0.91)]. Rehabilitated children had a higher mean weight gain in the first 3 months (1.63 compared to 0.56 weight-for-age standard deviation score, P < 0.001), and weight gain differences lasted up to 18 months (P < 0.01). CONCLUSIONS Low-cost, outreach NRCs are effective both in the short term and in the mid-term to improve the nutritional situation and reduce the mortality of severely malnourished children.

Abstract
Since there have been a few reports of pediatric HIV-2 infection. We therefore investigated the perinatal transmission of HIV-2 in 147 malnourished and 164 well-nourished children attending a health center in the northern part of Guinea Bissau. Specific HIV-2 antibodies were detected in 17 mothers and in 2 malnourished children, one of them with pediatric AIDS. This study demonstrates that mother to child transmission of HIV-2 infection occurs in Guinea Bissau and suggests that there is an increased likelihood of detecting HIV-2 infection in malnourished children. The high seroprevalence of HIV-2 in a rural population without known risk factors may represent a hidden threat to mother/child health.
