Transcriptomic landscape of TIMP3 oncosuppressor activity in thyroid carcinoma.

BACKGROUND: Papillary thyroid cancer (PTC) is the most frequent thyroid tumor. The tissue inhibitor of metalloproteinase-3 (TIMP3) gene encodes a matrix metalloproteinases inhibitor that exerts a tumor suppressor role in several tumor types. TIMP3 is frequently downregulated in PTC by promoter methylation. We have previously functionally demonstrated that TIMP3 exerts an oncosuppressor role in PTC: TIMP3 restoration in the PTC-derived NIM1 cell line affects in vitro migration, invasion and adhesive capability, while reduces tumor growth, angiogenesis and macrophage recruitment in vivo. To get a deeper insight on the mediators of TIMP3 oncosuppressor activity in thyroid tumors, here we focused on the TIMP3 related transcriptome. METHODS: TCGA database was used for investigating the genes differentially expressed in PTC samples with low and high TIMP3 expression. Genome wide expression analysis of clones NIM1-T23 (expressing a high level of TIMP3 protein) and NIM1-EV (control empty vector) was performed. Gene sets and functional enrichment analysis with clusterProfiler were applied to identify the modulated biological processes and pathways. CIBERSORT was used to evaluate the distribution of different immunological cell types in TCGA-PTC tumor samples with different TIMP3 expression levels. Real time PCR was performed for the validation of selected genes. RESULTS: Thyroid tumors with TIMP3-high expression showed a down-modulation of inflammation-related gene sets, along with a reduced protumoral hematopoietic cells fraction; an enrichment of cell adhesion functions was also identified. Similar results were obtained in the TIMP3-overexpessing NIM1 cells in vitro model, where a down-regulation of immune-related function gene sets, some of which also identified in tumor samples, was observed. Interestingly, through enrichment analysis, were also recognized terms related to cell adhesion, extracellular matrix organization, blood vessel maintenance and vascular process functions that have been found modulated in our previous in vitro and in vivo functional studies. CONCLUSIONS: Our results highlight the correlation of TIMP3 expression levels with the regulation of inflammatory functions and the immune infiltration composition associated with different PTC prognosis, thus providing a broader view on the oncosuppressor role of TIMP3 in PTC.

Interventions supporting cost conversations between patients and clinicians: A systematic review.

BACKGROUND AND AIM: Discussing cost during medical encounters may decrease the financial impact of medical care on patients and align their treatment plans with their financial capacities. We aimed to examine which interventions exist and quantify their effectiveness to support cost conversations. METHODS: Several databases were queried (Embase; Ovid MEDLINE(R); Epub Ahead of Print, In-Process & Other Non-Indexed Citations and Daily; the Cochrane databases; and Scopus) from their inception until January 31, 2020 using terms such as "clinician*", "patient*", "cost*", and "conversation*". Eligibility assessment, data extraction and risk of bias assessment were performed independently and in duplicate. We extracted study setting, design, intervention characteristics and outcomes related to patients, clinicians and quality metrics. RESULTS: We identified four studies (1327 patients) meeting our inclusion criteria. All studies were non-randomised and conducted in the United States. Three were performed in a primary care setting and the fourth in an oncology. Two studies used decision aids that included cost information; one used a training session for health care staff about cost conversations, and the other directly delivered information regarding cost conversations to patients. All interventions increased cost-conversation frequency. There was no effect on out-of-pocket costs, satisfaction, medication adherence or understanding of costs of care. CONCLUSION: The body of evidence is small and comprised of studies at high risk of bias. However, an increase in the frequency of cost conversations is consistent. Studies with higher quality are needed to ascertain the effects of these interventions on the acceptability, frequency and quality of cost conversations.

Localized gallbladder perforation: a systematic review of treatment and prognosis.

BACKGROUND: The optimal management of localized gallbladder perforation (Neimeier type II) has yet to be defined. The aim of this systematic review was to identify factors associated with improved patient outcomes. METHODS: Systematic review of studies that described the management of Neimeier type II perforation, reported complications of the first intervention, necessity of added interventions, resolution of the pathology, and days of hospital stay were included. The search strategy was conducted in EMBASE, Mayo Journals, MEDLINE, SCOPUS, and Web of Science (December 2020) RESULTS: A total of 122 patients (53% male) from case reports, series, and cohorts were included for analysis. In total 56 (46%) and 44 (36%)patients were treated with open and laparoscopic cholecystectomy respectively. Overall risk of bias was moderate. The need for another intervention was higher in the laparoscopic group (5 vs 17, p=<0.001) as well as prevalence of complications (4 vs 16, p=<0.001), but lower for days of hospital stay (median days 5. vs 15, p = 0.008) against open cholecystectomy. Preoperative percutaneous catheter drainage did not influence outcome. CONCLUSION: Open cholecystectomy has a lower need for further surgical procedures and postoperative complications, but a longer hospital stay. These outcomes did not vary with preoperative percutaneous drainage. The effect of timing of cholecystectomy did not influence the outcomes.

[Association of family typology and dysfunction in families with adolescents from a Mexican population]. / Asociación de tipología familiar y disfuncionalidad en familias con adolescentes de una población mexicana.

OBJECTIVE: To determine the association between family typology and dysfunction in families with adolescents in a Mexican population. DESIGN: Cross-sectional observational study. SETTING AND POPULATION: A total of 437 families in a Mexican population with adolescents attending a public high school. MAIN MEASUREMENTS: Determination of family typology (Mexican Family Medicine Council and Consensus) and family function (family APGAR) in adolescents and their parents/guardians. Identification of families with concordant perceptions among members (Cohen kappa), in which the association between typology and perception of family dysfunction was determined (odds ratio [OR]). RESULTS: The types of families are associated with family function by kinship, physical presence in the home and the level of family poverty. From the perception of the adolescent, the types are associated with: simple nuclear (OR 0.5, 95% CI 0.3-0.8), extended single parent (OR 1.9, 95% CI 1.03-3.5), integrated nucleus (OR 0.6, 95% CI 0.4-0.9), low family poverty (OR 0.5, 95% CI 0.3-0.8), and high family poverty (OR 5.3, 95% CI 1.5-18.6). From the perception of the tutor: the single parent (OR 1.9, 95% CI 1.09-3.4), and high family poverty (OR 2.9, 95% CI 1.1-7.7). There were 259 families with concordant perception of family function/dysfunction with a κ=0.189, determining that the types associated are: simple nuclear (OR 0.4, 95% CI 0.2-0.7), single-parent (OR 1.7, 95% CI 0.80-3.8), integrated nucleus (OR 0.5, 95% CI 0.3-0.8), non-integrated nucleus (OR 1.9, 95% CI 1.09-3.5), and high family poverty (OR 13.8, 95% CI 1.7-108.5). CONCLUSION: The family types with adolescents associated with family dysfunction are single-parent families with a non-integrated nucleus and high family poverty, and as protective factors, the simple nuclear and integrated nucleus.

Smoking and hypertension: Effect of adenosine deaminase polymorphism.

Adenosine modulates cardiovascular functions reducing blood pressure and heart rate. Adenosine deaminase (ADA) by the irreversible deamination of adenosine to inosine contributes to the regulation of adenosine concentration in body fluids. We have studied the interaction between smoking and ADA genetic variability concerning their effects on blood pressure. We have studied 344 subjects admitted to the hospital for cardiovascular diseases. The genotypes of two polymorphic loci within the ADA gene were determined: ADA1 and ADA2. Both loci show two alleles: ADA1*1 and ADA1*2 in ADA1 locus and ADA2*1 and ADA2*2 in ADA2 locus. In the absence of smoking, the proportion of subjects with hypertension tends to be lower in carriers of the ADA1*2 allele. In smoking subjects, the pattern is reversed and the proportion of those with hypertension tends to be higher in carriers of the ADA1*2 allele. A similar pattern is observed for ADA2 locus. Smoking increases the proportion of subjects showing hypertension: such effect is more marked in those carrying the ADA1*2 allele as compared to subjects with ADA1*1/*1 genotype. The same pattern of association is observed for ADA2 locus. The two loci show an additive effect. The odds ratio for hypertension in smokers vs nonsmokers is 1.450 in subjects carrying ADA1*1/*1 and ADA2*1/*1 genotypes, while it is 11.200 in subjects carrying the *2 alleles in both loci. From a practical point, a view of our results suggest that smokers carrying both ADA1*2 and ADA2*2 alleles have a higher risk of hypertension.

Measuring public knowledge, attitudes, and behaviors related to radon to inform cancer control activities and practices.

Radon exposure is the second leading risk factor for lung cancer among smokers and the leading risk factor among non-smokers. Radon concentrated in lower levels of homes/buildings can be reduced if found, thus lowering lung cancer risk. The objective of this study was to measure radon knowledge in diverse populations, with varying radon-related laws, to inform radon-related cancer control practices and activities. A survey was mailed to 3000 homebuyers who purchased single-family homes; 995 responses (33%) were received. Overall, 86% of respondents heard of radon-related health issues. Real estate agents (69%) or home inspectors (65%) were the most common sources of information. Respondents were more likely to test their home for radon if they reported previously hearing of radon-related health issues or understanding of how radon-related health issues affect the home-buying process. Respondents in states with notification policies were twice as likely as those without policies to have heard about radon-related health issues (OR 2.01, 95% CI: 1.27-3.17). This study provides useful information for cancer control activities including that education is positively associated with home testing for radon. It also suggests partnering with real estate agents to further radon education and testing efforts to reduce radon exposure and lung cancer risk.

Climate, demographic factors and geographical variations in the incidence of invasive meningococcal disease in Italy.

We investigated the effect of climatic, demographic factors and intra-country geographical variations on the incidence of invasive meningococcal disease (IMD) in Italy. For this purpose, incidence rates of IMD cases reported in Italy between 1994 and 2012 were calculated, and a cluster analysis was performed. A geographical gradient was determined, with lower incidence rates in central and southern Italy, compared to the northern parts, where most clusters were observed. IMD rates were higher in medium-sized towns than in villages. Adults were at lower risk of IMD than children aged ⩽4 years. IMD incidence tended to decrease with increasing monthly mean temperatures (incidence rate ratio 0·94, 95% confidence interval 0·90-0·99). In conclusion, geographical variations in IMD incidence were found, where age and temperature were associated with disease occurrence. Whether geographical variations should be considered in national intervention plans is still a matter for discussion.

A quantitative assessment of circulating progenitor cells in competitive athletes and in sedentary subjects.

AIM: Hematopoietic stem cells (HSCs) and endothelial progenitor cells (EPCs) are known to play a role in the vascular responses and adaptations to exercise. We performed a quantitative assessment of HSCs and EPCs in adolescents in order to investigate whether resting levels of circulating HSCs and EPCs are comparable between elite athletes and sedentary healthy subjects. METHODS: HSCs and EPCs levels were measured in adolescent competitive football players and in age- and sex-matched sedentary controls. A laboratory testing was also performed to determine the white blood cells count and the lipid profile. All athletes were evaluated at the same stage of their training program, after 6 months of training. Controls were not engaged in any kind of routine training program. RESULTS: Twenty male competitive athletes (18.4 ± 0.5 years) and 9 sedentary controls (18.7 ± 0.4 years) participated in the study. As expected, HDL cholesterol was higher in athletes as compared with controls (P<0.05). No significant differences in the other laboratory parameters were observed among groups. Circulating levels of HSCs were significantly lower in athletes in comparison with sedentary controls (P<0.05). Conversely, EPCs and KDR+ cell subpopulations did not substantially differ between athletes and controls. CONCLUSION: Adolescent athletes exhibit lower levels of circulating HSCs but not of EPCs compared to sedentary controls. The process of tissue repair associated with intensive training can contribute to this difference, acting as a stimulus for mobilization and homing of HSCs in the site of injuries.

[Use of TachoSil® in the entero-colic anastomoses: results of an observational study]. / TachoSil® nelle anastomosi entero-coliche: risultato di uno studio osservazionale.

AIM: In the last decade while many comparative studies examined hemostatic topics, adhesives and sealants, few clinical trials were made. We are focusing our attention particularly on TachoSil®, and studying its efficacy on reducing the frequency of anastomotic leakage, thought to be one of the causes of prolonged periods of patients' hospitalization. METHODS: We examined 188 patients who underwent colorectal and enteric surgery at our department between January 2010 and March 2013. The efficacy of fibrin glue was evaluated on a cohort of patients at risk of anastomosis leakage. To test the relationship between the application of TachoSil® and the type of complications, a multiple logistic regression model was implemented. Fisher exact Test was used to compare the relations between two groups. The Mann-Whitney test was used to account for the days necessary for the follow-up of the patients in the various units participating in the study. RESULTS: From the logistic regression model we can infer that TachoSil® is a highly protective factor though not statistically significant (OR=0.78; P>0.05). The results obtained analyzing the average days of patients hospitalization show a statistically significant decrease of such parameter in patients under treatment, especially those who underwent transverse colon resection (P<0.001). CONCLUSION: The results of this study show that TachoSil® is a highly protective factor, but its efficacy is not statistically significant due to the small number of patients treated. It is important to call the attention to the reduced number of the hospitalization needed for the patients under treatment.

The development of internal pressure standards for in-house elastic wave velocity measurements in multi-anvil presses.

Ultrasonic systems are powerful tools to determine elastic wave velocities of minerals and materials at high pressure and temperature and have been extensively developed in recent decades. However, accurate measurement of sample length is required to convert travel times into wave velocities, limiting their use to synchrotron facilities or room temperature experiments in laboratories. We have made use of a close collaboration between the Bayerisches Geoinstiut and the P61B end-station beamline (PETRA III - DESY) to install ultrasonic systems and develop a novel dual travel time method for in situ pressure determination without the need for synchrotron radiation. Our method relies on the travel times of elastic waves through a reference material; it requires a thermocouple and is non-intrusive, with the reference material replacing the backing plate of the high-pressure assembly. Pressures obtained from this dual travel time method show excellent agreement with those obtained from x-ray diffraction using synchrotron radiation on standard materials. Our novel method enables in situ pressure determination at varying temperatures during in-house ultrasonic interferometry experiments. This allows us not only to determine the elastic behavior of minerals and materials but also to investigate phase diagrams, solidus, or liquidus conditions at varying pressures and temperatures during in-house experiments. During the installation of the pulse-echo ultrasonic system, we identified critical parameters for obtaining reliable data. While these requirements are well-known to experts, this study presents a comprehensive review of the different characteristics of ultrasonic systems, providing user-friendly guidelines for new users installing and operating such systems in high-pressure and high-temperature conditions.

Factors associated with non-treatment of hypertension and gender differences at baseline in the ELSA-Brasil cohort.

The treatment of arterial hypertension (AH) contributes to the reduction of morbidity and mortality. Gender differences are likely to play a role, as non-treatment is associated with clinical and sociodemographic aspects. The aim of this study was to investigate the factors associated with non-treatment of AH and gender differences in hypertensive individuals from the ELSA-Brasil cohort. The study was conducted with 5,743 baseline hypertensive cohort participants. AH was considered if there was a previous diagnosis or if systolic blood pressure (SBP) was ≥140 and/or diastolic BP (DBP) was ≥90 mmHg. Sociodemographic and anthropometric data, lifestyle, comorbidities, and use of antihypertensive medications were evaluated through interviews and in-person measurements. Treatment with renin-angiotensin-aldosterone system inhibitors (RAASi) or other antihypertensive medications and non-treatment were evaluated with multivariate logistic regression. Non-treatment was observed in 32.8% of hypertensive individuals. Of the 67.7% treated individuals, 41.1% received RAASi. Non-treatment was associated with alcohol consumption in women (OR=1.41; 95%CI: 1.15-1.73; P=0.001), lowest schooling level in men (OR=1.70; 95%CI: 1.32-2.19; P<0.001), and younger age groups in men and women (strongest association in males aged 35-44 years: OR=4.58, 95%CI: 3.17-6.6, P<0.001). Among those using RAASi, a higher proportion of white, older individuals, and with more comorbidities was observed. The high percentage of non-treatment, even in this civil servant population, indicated the need to improve the treatment cascade for AH. Public health policies should consider giving special attention to gender roles in groups at higher risk of non-treatment to reduce inequities related to AH in Brazil.

Reggio Emilia (Northern Italy) Interdisciplinary Uveitis Clinic: What We Have Learned in the Last 20 Years.

PURPOSE: To analyze the referral patterns and the clinical and therapeutic features of patients diagnosed with uveitis in an Italian tertiary referral center to provide a comparison with previously published series from the same center. METHODS: Retrospective retrieval of data on all new referrals to the Ocular Immunology Unit in Reggio Emilia (Italy) between November 2015 and April 2022 and comparison with previously published series from the same center. RESULTS: Among the 1557 patients, the male-to-female ratio was 1:1.27. Anterior uveitis was the most common diagnosis (53.7%), followed by posterior (21.6%), pan- (18.5%), and intermediate (6.2%) uveitis. The most identifiable specific diagnoses were anterior herpetic uveitis (18.4%), Fuchs uveitis (12.8%), and tuberculosis (6.1%). Infectious etiologies were the most frequent (34.1%) and were more diffuse among non-Caucasian patients (p < 0.001), followed by systemic disease-associated uveitis (26.5%), and ocular-specific conditions (20%). Idiopathic uveitis accounted for 19.4% of cases. Fuchs uveitis presented the longest median diagnostic delay (21 months). Immunosuppressants were administered to 25.2% of patients. Antimetabolites, calcineurin inhibitors, and biologicals were prescribed to 18.4%, 3%, and 11.4% of cases, respectively. Compared to our previous reports, we observed a significant increase in foreign-born patients and in infectious uveitis, a decrease in idiopathic conditions, and an increasing use of non-biological and biological steroid-sparing drugs. CONCLUSIONS: The patterns of uveitis in Italy have been changing over the last 20 years, very likely due to migration flows. Diagnostic improvements and a more widespread interdisciplinary approach could reduce the incidence of idiopathic uveitis as well as diagnostic delay.

[Aberrant immunophenotypes in acute leukemia in a Buenos Aires' hospital population]. / Inmunofenotipos aberrantes en leucemias agudas en una población hospitalaria de Buenos Aires.

Multiparameter flow cytometry (MFC) has become the preferred method for the lineage assignment and maturational analysis of malignant cells in acute leukemias. Multiparametric immunophenotyping analysis allows the detection of aberrant antigen expression and the analysis of heterogeneity and clonality of malignant cells in leukemias. Our objectives were to analyze the membrane antigen expression and to evaluate if the aberrant phenotypes occurrence in blasts cells of patients with acute leukemia is useful in monitoring the response to the treatment. We have retrospectively analyzed the MFC data of 364 samples sent to our laboratory in a 7 years period. For this purpose we have used a large panel of monoclonal antibodies against lymphoid, myeloid and precursors antigens. From the 364 analyzed samples, 60.2% showed a phenotype compatible with acute myeloid leukemia (AML), 28.8% with B lymphoblastic leukemia (B-LLA), 6.6% with T lymphoblastic leukemia (T-LLA) and 4.4% with rare leukemias. Aberrant phenotypes were found in 86% of the samples. The aberrant phenotypes identified were:1) lineage infidelity AML (54%), B-ALL (40%), T-ALL (29%); 2) absence of antigen expression: AML (21%), B-ALL (35%), T-ALL (70%); 3) altered antigen expression: AML (67%), B-ALL (66%),T-ALL (84%); 4) asynchronous expression: AML (26%), B-ALL (37%) and 5) ectopic phenotype: T-ALL (96%). Multiparameter flow cytometry of acute leukemias allowed identification of aberrant phenotypes in the majority of our patients, that are helpful for monitoring treatment response.

Preliminary assessment of persistent organic pollutants (POPs) in tissues of Risso's dolphin (Grampus griseus) specimens stranded along the Italian coasts.

Ecotoxicological and pathological research on Grampus griseus (Cuvier, 1812) (Risso's dolphins) is scarce both globally and in the Mediterranean Sea. This species has been classified as "Vulnerable" by the International Union for Conservation of Nature (IUCN) in the Mediterranean Sea. To evaluate the presence of "persistent organic pollutants" (POPs), especially organochlorine compounds (OCs), in the animals, chemical analyses were performed on tissues and organs of Risso's dolphin stranded along the Italian coasts between 1998 and 2021. Toxic contaminants such as hexachlorobenzene (HCB), polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane and its metabolites (DDTs) were examined in the blubber, liver, muscle, and brain of 20 animals, and data was correlated with sex, age, and stranding locations.

Harms of third- and fourth-generation combined oral contraceptives in premenopausal women: A systematic review and meta-analysis.

We assessed the available evidence regarding adverse effects on surrogate and patient-important health outcomes of third- and fourth-generation combined oral contraceptives among premenopausal women. We performed a systematic review and meta-analysis including randomized controlled trials and observational studies comparing third- and fourth-generation combined oral contraceptives with other generation contraceptives or placebo. Studies that enrolled women aged 15 to 50 years, with at least three cycles of intervention and 6 months of follow-up were included. A total of 33 studies comprising 629,783 women were included. Low-density lipoprotein cholesterol levels were significantly lower in fourth-generation oral contraceptives (mean differences (MD): -0.24 mmol/L; [95% CI -0.39 to -0.08]), while total cholesterol was significantly increased in levonorgestrel users when compared to third-generation oral contraceptives (MD: 0.27 mmol/L; [95% CI 0.04 to 0.50]). A decreased arterial thrombosis incidence was shown in fourth-generation oral contraceptive users, as compared to levonorgestrel (incidence rate ratio (IRR): 0.41; [95% CI 0.19 to 0.86]). No difference was found in the occurrence of deep venous thrombosis between fourth-generation oral contraceptives and levonorgestrel users (IRR: 0.91; [95% CI 0.66 to 1.27]; p = 0.60; I2 = 0%). Regarding the remaining outcomes, data were heterogeneous and showed no clear difference. In premenopausal women, the use of third- and fourth-generation oral contraceptives is associated with an improved lipid profile and lower risk of arterial thrombosis. Data were inconclusive regarding the rest of outcomes assessed. This review was registered in PROSPERO with CRD42020211133.

Insulin resistance in bipolar disorder: A systematic review of illness course and clinical correlates.

BACKGROUND: Although insulin resistance (IR) and cardiometabolic syndrome are prevalent in patients with bipolar disorder (BD), only a few studies have attempted to precisely assess the degree and clinical impact of IR in BD. METHODS: A comprehensive search was conducted from multiple research databases through May 2022, following a pre-defined protocol (PROSPERO: CRD42022359259). We extracted neuroimaging, cognition, illness course, and treatment response findings from individuals with BD with evidence of IR compared with euglycemic BD individuals. RESULTS: Of 1436 identified articles, 10 reports fulfilling inclusion criteria were included (n = 1183). BD patients with IR displayed worse composite verbal memory scores and worse executive function and exhibited smaller hippocampal volumes along with prefrontal neurochemical alterations compared to euglycemic BD patients. Fixed-effect meta-analysis revealed that BD patients with impaired glucose metabolism (IGM) were more likely to develop a chronic and rapid cycling course when compared with euglycemic BD patients (k = 2, OR = 2.96, 95 % CI 1.69-5.17, OR = 2.88, 95 % CI 1.59-5.21, p < 0.001, respectively), with a trend for significantly lower Global Assessment of Functioning scores (k = 5, MD = -4, 95 % CI -8.23-0.23, p = 0.06). BD patients with IGM displayed a higher rate of poor response to mood stabilizers when compared with euglycemic BD patients (k = 2, OR = 6.74, 95 % CI 1.04-43.54, p = 0.04). LIMITATIONS: Cross-sectional design and small sample sizes of studies included limit the generalizability of results. CONCLUSION: IR is associated with worse clinical outcomes of BD and inadequate treatment response. Implementing strategies to prevent and treat IR in BD is crucial to improve the prognosis of such a difficult-to-treat population.

The impact of health and wellness coaching on patient-important outcomes in chronic illness care: A systematic review and meta-analysis.

BACKGROUND: Health and Wellness Coaching (HWC) may be beneficial in chronic condition care. We sought to appraise its effectiveness on quality of life (QoL), self-efficacy (SE), depression, and anxiety. METHODS: We searched MEDLINE, EMBASE, CINAHL, PsycINFO, and Cochrane CENTRAL for randomized trials published January 2005 - March 2023 that compared HWC to standard clinical care or another intervention without coaching. We examined QoL, SE, depression, or anxiety outcomes. Meta-analysis utilizing the random-effects model was used to estimate the pooled standardized mean difference (SMD). RESULTS: Thirty included studies demonstrated that HWC improved QoL within 3 months (SMD 0.62 95 % CI 0.22-1.02, p = 0.002), SE within 1.5 months (SMD 0.38, 95 % CI 0.03-0.73, p = 0.03), and depression at 3, 6, and 12 months (SMD 0.67, 95 % CI 0.13-1.20, p = 0.01), (SMD 0.72, 95 % CI 0.19-1.24, p = 0.006), and (SMD 0.41, 95 % CI 0.09-0.73, p = 0.01) Certainty in the evidence for most outcomes was either very low or low primarily due to the high risk of bias, heterogeneity, and imprecision. CONCLUSION: HWC improves QoL, SE, and depression across chronic illness populations. Future research needs to standardize intervention reporting and outcome collection. PRACTICE IMPLICATIONS: Future HWC studies should standardize intervention components, reporting, and outcome measures, apply relevant chronic illness theories, and aim to follow participants for greater than one year.

Epidemiology of hepatitis D virus (HDV) infection in an urban area of northern Italy.

OBJECTIVES: The introduction of vaccination against hepatitis B initially reduced the number of HBV (hepatitis B virus) and HDV (hepatitis delta virus) infections, but the decreasing trend of HDV infection seems to have stopped. The aim of this study was to assess the prevalence of HDV infection in the general population living in the catchment area of Legnano Hospital in northern Italy. METHODS: Of the 22,758 subjects tested in 2007-2008, the 488 who were HBsAg (hepatitis B surface antigen)-positive [including 107 (21.9%) of non-Italian origin] were subsequently tested for anti-HDV antibodies. RESULTS: Of the 488 subjects who tested positive for HBsAg, 24 (4.9%) were anti-HDV positive, all aged between 30 and 60 years. The difference in prevalence between males (7.1%) and females (1.9%) was statistically significant (p < 0.05), but not that between Italian (5.0%) and non-Italian patients (4.7%). The differences in anti-HDV seropositivity between the patients with acute (0%) and chronic infections (6.3%), and between the incident (2.5%) and prevalent cases (7.4%), were not statistically significant, but there was a significant difference (p < 0.01) between those with asymptomatic (2.1%) and clinically symptomatic infections (10.3%). Intravenous drug abuse was the main source of infection. CONCLUSIONS: In the catchment area of our hospital, the prevalence of HDV infection does not seem to be due to patients of non-Italian origin, but to Italian patients who are not vaccinated against HBV and who survived the HDV epidemic of the 1970s and 1980s. Nevertheless, the increase in the number of immigrants from non-EU countries in recent years is soon likely to lead to a change in the epidemiology of HDV.

Cluster of invasive Neisseria meningitidis infections on a cruise ship, Italy, October 2012.

We describe a cluster of four cases of invasive meningococcal disease that occurred on a cruise ship sailing along the Italian coast in October 2012. All four cases were hospitalised with severe illness and one of them died. This report illustrates the importance of rapid implementation of emergency control measures such as administration of prophylaxis to all crew members and passengers to prevent the spread of the disease in such a close environment.
