Impact of rhinovirus nasopharyngeal viral load and viremia on severity of respiratory infections in children. Eur J Clin Microbiol Infect Dis 2013; 33:41-8.

Abstract
There are few and partially discordant data regarding nasopharyngeal rhinovirus (RV) load and viremia, and none of the published studies evaluated the two variables together. The aim of this study was to provide new information concerning the clinical relevance of determining nasopharyngeal viral load and viremia when characterising RV infection. Nasopharyngeal swabs were obtained from 251 children upon their admission to hospital because of fever and signs and symptoms of acute respiratory infection in order to identify the virus and determine its nasopharyngeal load, and a venous blood sample was taken in order to evaluate viremia. Fifty children (19.9 %) had RV-positive nasopharyngeal swabs, six (12 %) of whom also had RV viremia: RV-C in four cases (66.6 %), and RV-A and RV-B in one case each. The RV nasopharyngeal load was significantly higher in the children with RV viremia (p < 0.001), who also had a higher respiratory rate (p = 0.02), white blood cell counts (p = 0.008) and C-reactive protein levels (p = 0.006), lower blood O2 saturation levels (P = 0.005), and more often required O2 therapy (p = 0.009). The presence of RV viremia is associated with a significantly higher nasopharyngeal viral load and more severe disease, which suggests that a high nasopharyngeal viral load is a prerequisite for viremia, and that viremia is associated with considerable clinical involvement.

Abstract
BACKGROUND The number of original articles investigating the efficacy of cosmetic products in cellulite reduction increased rapidly in the last decade; however, to our knowledge, no systematic review and meta-analysis has been performed so far. OBJECTIVE We conducted a systematic review of in vivo studies on humans adopting the PRISMA guidelines. Moreover, we used a meta-analytic approach to estimate the overall effect of cosmetic creams in cellulite treatment from controlled trials with more than 10 patients per arm, using thigh circumference reduction as the outcome measure. METHODS Medline and Embase were searched up to August 2012 to identify eligible studies. RESULTS Twenty-one original studies were included in the present systematic review. All studies were clinical trials, most of them recruited women only and 67% had an intra-patient study design. About half of the active cosmetic creams tested only contained one active ingredient among xanthenes, herbals or retinoids. The other studies tested cosmetic creams with more complex formulations and most of them included xanthenes. A total of seven controlled trials satisfied the inclusion criteria for the meta-analysis. The pooled mean difference of thigh circumference reduction between the treated and the controlled group was -0.46 cm (95% confidence intervals, CI: -0.85, -0.08), with significant heterogeneity between studies (P < 0.001). CONCLUSION This article provides a systematic evaluation of the scientific evidence of the efficacy of cosmetic products in cellulite reduction and supports a moderate efficacy in thigh circumference reduction.

Abstract
AIMS The aim of this consensus paper is to review the available evidence on the association between moderate alcohol use, health and disease and to provide a working document to the scientific and health professional communities. DATA SYNTHESIS In healthy adults and in the elderly, spontaneous consumption of alcoholic beverages within 30 g ethanol/d for men and 15 g/d for women is to be considered acceptable and do not deserve intervention by the primary care physician or the health professional in charge. Patients with increased risk for specific diseases, for example, women with familiar history of breast cancer, or subjects with familiar history of early cardiovascular disease, or cardiovascular patients should discuss with their physician their drinking habits. No abstainer should be advised to drink for health reasons. Alcohol use must be discouraged in specific physiological or personal situations or in selected age classes (children and adolescents, pregnant and lactating women and recovering alcoholics). Moreover, the possible interactions between alcohol and acute or chronic drug use must be discussed with the primary care physician. CONCLUSIONS The choice to consume alcohol should be based on individual considerations, taking into account the influence on health and diet, the risk of alcoholism and abuse, the effect on behaviour and other factors that may vary with age and lifestyle. Moderation in drinking and development of an associated lifestyle culture should be fostered.

Abstract
BACKGROUND Findings on pet exposure and the risk of atopic dermatitis (AD) in children are inconsistent. OBJECTIVE With the aim to summarize the results of exposure to different pets on AD, we undertook a meta-analysis of epidemiologic studies on this issue. METHODS In August 2012, we conducted a systematic literature search in Medline and Embase. We included analytic studies considering exposure to dogs, cats, other pets, or pets overall during pregnancy, infancy, and/or childhood, with AD assessment performed during infancy or childhood. We calculated summary relative risks and 95% CIs using both fixed- and random-effects models. We computed summary estimates across selected subgroups. RESULTS Twenty-six publications from 21 birth cohort studies were used in the meta-analyses. The pooled relative risks of AD for exposure versus no exposure were 0.72 (95% CI, 0.61-0.85; I(2) = 46%; results based on 15 studies) for exposure to dogs, 0.94 (95% CI, 0.76-1.16; I(2) = 54%; results based on 13 studies) for exposure to cats, and 0.75 (95% CI, 0.67-0.85; I(2) = 54%; results based on 11 studies) for exposure to pets overall. No heterogeneity emerged across the subgroups examined, except for geographic area. CONCLUSION This meta-analysis reported a favorable effect of exposure to dogs and pets on the risk of AD in infants or children, whereas no association emerged with exposure to cats.

Abstract
BACKGROUND Alcohol is capable of traversing the blood-brain barrier and is thus a possible risk factor for brain cancer. Several epidemiological studies have been published on the issue, a number of those during recent years, with inconsistent findings. MATERIALS AND METHODS We performed a systematic literature search in the Medline and EMBASE databases. We found a total of 19 studies providing risk estimates for total alcohol or specific alcoholic beverages. Pooled estimates of the relative risks (RR) and 95% confidence intervals (CI) were calculated using random-effects models. RESULTS The pooled RR of brain cancer for alcohol drinkers versus non-drinkers was 0.97 (95% CI 0.82-1.15; based on 12 studies). Moderate (<2 drinks/day) and heavy alcohol drinkers had RRs of 1.01 (95% CI 0.81-1.25) and 1.35 (95% CI 0.85-2.15), respectively. With reference to specific alcoholic beverages, the RRs were 1.01 (95% CI 0.70-1.48) for wine, 0.96 (95% CI 0.82-1.12) for beer, and 1.20 (95% CI 1.01-1.42) for spirit consumption. The RRs for drinkers versus non-drinkers were 0.93 (95% CI 0.81-1.07) for glioma and 0.71 (95% CI 0.45-1.12) for meningioma. CONCLUSIONS Alcohol drinking does not appear to be associated with adult brain cancer, though a potential effect of high doses deserves further study.

Abstract
BACKGROUND There is convincing evidence that alcohol consumption increases the risk of cancer of the colorectum, breast, larynx, liver, esophagus, oral cavity and pharynx. Most of the data derive from studies that focused on the effect of moderate/high alcohol intakes, while little is known about light alcohol drinking (up to 1 drink/day). PATIENTS AND METHODS We evaluated the association between light drinking and cancer of the colorectum, breast, larynx, liver, esophagus, oral cavity and pharynx, through a meta-analytic approach. We searched epidemiological studies using PubMed, ISI Web of Science and EMBASE, published before December 2010. RESULTS We included 222 articles comprising ∼92 000 light drinkers and 60 000 non-drinkers with cancer. Light drinking was associated with the risk of oropharyngeal cancer [relative risk, RR = 1.17; 95% confidence interval (CI) 1.06-1.29], esophageal squamous cell carcinoma (SCC) (RR = 1.30; 95% CI 1.09-1.56) and female breast cancer (RR = 1.05; 95% CI 1.02-1.08). We estimated that ∼5000 deaths from oropharyngeal cancer, 24 000 from esophageal SCC and 5000 from breast cancer were attributable to light drinking in 2004 worldwide. No association was found for colorectum, liver and larynx tumors. CONCLUSIONS Light drinking increases the risk of cancer of oral cavity and pharynx, esophagus and female breast.

Abstract
This study was conducted to evaluate the association between pneumococcal DNA load and parapneumonic pleural effusion (PPE) in children with community-acquired pneumonia. Bacterial load was quantified and related to the presence of PPE with or without empyema in 72 otherwise healthy children aged ≤5 years who were hospitalised because of radiographically confirmed CAP and showed a real-time polymerase chain reaction that was positive for Streptococcus pneumoniae. The proportion of children with a high bacterial load (i.e. ≥265 DNA copies/mL) was larger among the subjects with PPE than those without it. Multivariate analysis showed that a high bacterial load was significantly associated with PPE (OR 8.65; 95% CI 1.10-67.8 vs a bacterial load of <125 copies/mL). Children with infection due to pneumococcal serotype 19A were at highest risk of developing PPE (OR 7.44; 95% CI 1.10-50.4 vs all other typeable serotypes). The patients with CAP due to pneumococcal serotypes that are not included in the 13-valent conjugate vaccine (PCV13) were more frequently affected by PPE than those with infections associated with serotypes included in the vaccine, except for serotype 19A. Bacterial loads of ≥265 DNA copies/mL are significantly associated with PPE, and serotype 19A is significantly associated with a high bacterial load and the development of PPE. The mean bacterial load of the patients with empyema was higher than that of patients with simple PPE. Although further studies are required, it seems that serotypes not included in PCV13 can play a major role in causing a higher bacterial load and PPE.

Abstract
As vitamin D (VD) has a significant regulatory effect on innate and adaptive immunity, the aim of this prospective, randomized, single-blinded, placebo-controlled study was to measure the impact of VD administration on the immune response to trivalent influenza vaccination (TIV). A total of 116 children (61 males, 52.6%; mean age 3.0 ± 1.0 y) with a history of recurrent acute otitis media (AOM), who had not been previously vaccinated against influenza, were randomized to receive daily VD 1,000 IU or placebo by mouth for four months. All of them received two doses of TIV (Fluarix, GlaxoSmithKline Biologicals) one month apart, with the first dose administered when VD supplementation was started. There was no difference in seroconversion or seroprotection rates, or antibody titers, in relation to any of the three influenza vaccine antigens between the VD and placebo groups, independently of baseline and post-treatment VD levels. The safety profile was also similar in the two groups. These data indicate that the daily administration of VD 1,000 IU for four months from the time of the injection of the first dose of TIV does not significantly modify the antibody response evoked by influenza vaccine.

Abstract
BACKGROUND Coffee contains many compounds, including antioxidants, which could prevent cancerogenesis, and coffee has been related with lower incidence of cancer at several sites. Tea is also rich in antioxidants, mainly polyphenols. To provide a quantitative overall estimate on the relation between coffee and tea consumption and glioma, we combined all published data, using a meta-analytic approach. METHODS In September 2012, a bibliography search was carried out in both PubMed and Embase to identify observational studies providing quantitative estimates on the issue. Pooled estimates of the relative risks (RR) and the corresponding 95 % confidence intervals (CI) were calculated using random-effects models. RESULTS Six studies (four cohort and two case-control studies) were available for meta-analysis, for a total of about 2100 cases. The summary RRs and 95 % CIs of glioma for drinkers versus non/occasional drinkers were 0.96 (95 % CI: 0.81-1.13) for coffee and 0.86 (95 % CI: 0.78-0.94) for tea, with no heterogeneity between studies. When we compared the highest versus the lowest categories of consumption, the RRs were 1.01 (95 % CI: 0.83-1.22) for coffee, 0.88 (95 % CI: 0.69-1.12) for tea, and 0.75 (95 % CI: 0.54-1.05) for coffee plus tea. CONCLUSIONS This meta-analysis, although based on few studies, suggests a lack of association between coffee intake and glioma risk, and a tendency, if any, to a lower risk for tea and coffee plus tea drinkers.

Abstract
BACKGROUND Toll-like receptors (TLRs) form an essential part of the innate immune system, which plays a fundamental role in rapidly and effectively controlling infections and initiating adaptive immunity. There are no published data concerning the importance of polymorphisms of TLRs in conditioning susceptibility to influenza or the severity of the disease. The aim of this study was to evaluate whether selected polymorphisms of TLR2, TLR3 and TLR4 influence the incidence and clinical picture of pandemic A/H1N1/2009 influenza. RESULTS The study involved 272 healthy children attending our Emergency Room for influenza-like illness (ILI), including 51 (18.8%) with pandemic A/H1N1/2009 influenza as revealed by real-time polymerase chain reaction, and 164 healthy controls examined after minor surgery. Genomic DNA was extracted from whole blood samples and five single-nucleotide polymorphisms (SNPs) were studied: TLR2 rs5743708, TLR3 rs5743313, TLR3 rs5743315, TLR4 rs4986790 and TLR4 rs4986791. The TLR3 rs5743313/CT polymorphism was found in all of the children with pneumonia and influenza infection, but in a significantly smaller number of those with A/H1N1/2009 influenza without pneumonia (<0.0001). TLR2, TLR3 rs5743315/AC and TLR4 polymorphisms were equally distributed in all of the groups regardless of the presence of the pandemic A/H1N1/2009 virus and clinical diagnosis. Viral load was comparable in all of the study groups. CONCLUSIONS There is a close relationship between the presence of TLR3 rs5743313/CT and an increased risk of pneumonia in children infected by the pandemic A/H1N1/2009 influenza virus.

Abstract
BACKGROUND Whether an association between alcohol drinking and non-Hodgkin lymphoma (NHL) risk exists is an open question. In order to provide quantification of the issue, we carried out a meta-analysis of published data. METHODS We identified 21 case-control and 8 cohort studies, including a total of 18,759 NHL cases. We derived meta-analytic estimates using random-effects models, taking into account correlation between estimates. RESULTS The overall relative risk (RR) of NHL for drinkers versus non-drinkers was 0.85 [95% confidence interval (CI) 0.79-0.91]. Compared with non-drinkers, the pooled RRs were 0.88 for light (≤1 drink per day), 0.87 for moderate (1 to <4 drinks per day), and 0.84 for heavy (≥4 drinks per day) alcohol drinking. There was no association for light drinkers in cohort studies, whereas for moderate and heavy drinkers, the RRs were similar in case-control (0.85 for moderate, 0.92 for heavy) and cohort (0.89 for moderate, 0.79 for heavy) studies. The inverse relation with alcohol consumption (drinkers versus non-drinkers) was similar in men (RR = 0.83) and women (RR = 0.86), but apparently stronger in studies from Asia (RR = 0.69) than other world areas (RR = 0.88). CONCLUSION This meta-analysis provides quantitative evidence of a favourable role of alcohol drinking on NHL risk, though the lack of a biological explanation suggests caution in the interpretation of results.

Abstract
BACKGROUND Depression is one of the most frequently missed diagnoses in elderly people, with obvious negative effects on quality of life. Various studies have shown that long chain omega-3 polyunsaturated fatty acids (n-3 PUFA) may be useful in its management. Our objective was to evaluate whether a supplement containing n-3 PUFA improves depressive symptoms in depressed elderly patients, and whether the blood fatty acid pattern is correlated with these changes. METHODS The severity of depressive symptoms according to the Geriatric Depression Scale (GDS), blood fatty acid composition and erythrocyte phospholipids were analyzed in 46 depressed females aged 66-95y, diagnosed with depression according to DSMIV, within the context of a randomized, double-blind, placebo-controlled trial. 22 depressed females were included in the intervention group (2.5 g/day of n-3 PUFA for 8 weeks), and 24 in the placebo group. We also measured immunological parameters (CD2, CD3, CD4, CD8, CD16, CD19 and cytokines (IL-5, IL-15). RESULTS The mean GDS score and AA/EPA ratio, in whole blood and RBC membrane phospholipids, were significantly lower after 2 months supplementation with n-3 PUFA. A significant correlation between the amelioration of GDS and the AA/EPA ratio with some immunological parameters, such as CD2, CD19, CD4, CD16 and the ratio CD4/CD8, was also found. Nevertheless, omega-3 supplementation did not significantly improve the studied immunological functions. CONCLUSIONS n-3 PUFA supplementation ameliorates symptoms in elderly depression. The n-3 PUFA status may be monitored by means of the determination of whole blood AA/EPA ratio.

Abstract
BACKGROUND The role of alcohol consumption in relation with renal cell carcinoma is still unclear; a few studies have reported a beneficial effect of moderate levels of alcohol consumption, whereas it remains still under debate whether there is a dose-response association. MATERIALS AND METHODS Twenty observational studies (4 cohort, 1 pooled and 15 case-control) reporting results on at least three levels of alcohol consumption were selected through a combined search with PubMed and EMBASE of articles published before November 2010. Overall relative risks (RRs) and 95% confidence intervals (CIs) were estimated using random-effects models, and both second-order fractional polynomials and random effect meta-regression models were implemented for the study of dose-risk relation. RESULTS The estimated RRs were 0.85 (95% CI: 0.80-0.92) for any alcohol drinking, 0.90 (95% CI: 0.83-0.97) for light drinking (0.01-12.49 g/day), 0.79 (95% CI: 0.71-0.88) for moderate drinking (12.5-49.9 g/day) and 0.89 (95% CI: 0.58-1.39) for heavy drinking (≥50 g/day), respectively. CONCLUSION Our meta-analysis supports the hypothesis of a negative effect of moderate alcohol consumption on the risk of renal cell cancer.

Abstract
BACKGROUND Folate deficiency leads to DNA damage and inadequate repair, caused by a decreased synthesis of thymidylate and purines. We analyzed the relationship between dietary folate intake and the risk of several cancers. PATIENTS AND METHODS The study is based on a network of case-control studies conducted in Italy and Switzerland in 1991-2009. The odds ratios (ORs) for dietary folate intake were estimated by multiple logistic regression models, adjusted for major identified confounding factors. RESULTS For a few cancer sites, we found a significant inverse relation, with ORs for an increment of 100 μg/day of dietary folate of 0.65 for oropharyngeal (1467 cases), 0.58 for esophageal (505 cases), 0.83 for colorectal (2390 cases), 0.72 for pancreatic (326 cases), 0.67 for laryngeal (851 cases) and 0.87 for breast (3034 cases) cancers. The risk estimates were below unity, although not significantly, for cancers of the endometrium (OR = 0.87, 454 cases), ovary (OR = 0.86, 1031 cases), prostate (OR = 0.91, 1468 cases) and kidney (OR = 0.88, 767 cases), and was 1.00 for stomach cancer (230 cases). No material heterogeneity was found in strata of sex, age, smoking and alcohol drinking. CONCLUSIONS Our data support a real inverse association of dietary folate intake with the risk of several common cancers.

Abstract
In order to investigate whether the persistently high incidence of malaria in Burundi is due to a lack of knowledge of the disease, mothers of children admitted to the hospital of Kiremba in Burundi were anonymously administered a semi-structured questionnaire about malaria. A total of 539 questionnaires were evaluated. About 75% of the women knew that malaria is transmitted by mosquitoes, and respectively 58.3 and 23.9% knew that it could lead to the death of a fetus or a low birth weight. Fewer than half of the women (44.7%) knew that malaria can be definitely diagnosed by means of a blood examination and only 39.7% indicates that artesunate-amodiaquine was the first-line therapy recommended by the Burundian health authorities. Long-lasting insecticidal or insecticide-treated nets were used by only 33.0%. Burundian women generally know little about malaria. Public awareness programmes should be conducted before any malaria control initiatives are planned.

Abstract
The European Society for Clinical Microbiology and Infectious Diseases established the Sore Throat Guideline Group to write an updated guideline to diagnose and treat patients with acute sore throat. In diagnosis, Centor clinical scoring system or rapid antigen test can be helpful in targeting antibiotic use. The Centor scoring system can help to identify those patients who have higher likelihood of group A streptococcal infection. In patients with high likelihood of streptococcal infections (e.g. 3-4 Centor criteria) physicians can consider the use of rapid antigen test (RAT). If RAT is performed, throat culture is not necessary after a negative RAT for the diagnosis of group A streptococci. To treat sore throat, either ibuprofen or paracetamol are recommended for relief of acute sore throat symptoms. Zinc gluconate is not recommended to be used in sore throat. There is inconsistent evidence of herbal treatments and acupuncture as treatments for sore throat. Antibiotics should not be used in patients with less severe presentation of sore throat, e.g. 0-2 Centor criteria to relieve symptoms. Modest benefits of antibiotics, which have been observed in patients with 3-4 Centor criteria, have to be weighed against side effects, the effect of antibiotics on microbiota, increased antibacterial resistance, medicalisation and costs. The prevention of suppurative complications is not a specific indication for antibiotic therapy in sore throat. If antibiotics are indicated, penicillin V, twice or three times daily for 10 days is recommended. At the present, there is no evidence enough that indicates shorter treatment length.

Abstract
BACKGROUND This study was designed to determine the proportion of bacteremic pneumococcal cases in a group of pediatric subjects with community-acquired pneumonia (CAP), the importance of the different serotypes and the impact of the currently available pneumococcal conjugate vaccines (PCVs). METHODS The study involved children who were ≤5 years with radiographically confirmed CAP admitted to hospital in Italy between September 2008 and March 2011. A diagnosis of laboratory-confirmed bacteremic pneumococcal CAP was made in the presence of a culture and/or real-time polymerase chain reaction (PCR) positive for Streptococcus pneumoniae. RESULTS A total of 510 children were included in the study. Pneumococcal CAP was diagnosed in 73 cases (14.3%): S. pneumoniae was identified by means of positive real-time PCR in 67 cases (91.8%), a positive blood culture in 1 (1.4%) and both in 5 (6.8%). Complicated pneumonia was observed significantly more often in the pneumococcal-positive cases (P=0.02) and empyema was the main complication (P=0.007). Serotype 19A was most frequently encountered (17 cases; 25.8%), followed by serotypes 14 (10 cases, 15.1%), 4 (5 cases, 7.6%) and 3 (4 cases, 6.1%). The theoretical coverage offered by the available PCVs was calculated to be 31% for PCV7, 37% for PCV10 and 71% for PCV13. CONCLUSIONS In Italy, bacteremic pneumococcal CAP accounts for a significant number of CAP cases in children who were ≤5 years, with serotypes 19A and 14 being the most frequent. This suggests that PCV13 is the best means of preventing pneumococcal CAP.

Abstract
PURPOSE OF REVIEW There is a growing body of in-vivo evidences that sucrose-rich diets cause mutations in the rat colon epithelium, with several biological mechanism hypothesized, but epidemiological studies have yielded conflicting results. In order to provide a quantification of the magnitude of the risk of colon cancer for high intake of added sugar, high dietary glycemic index and glycemic load, we performed a meta-analysis based on a systematic review of the literature to date. RECENT FINDINGS Recent epidemiological data indicate a lack of association between high intake of added sugar, high-glycemic index and glycemic load diets and risk of colon cancer. SUMMARY There is no consistent evidence from epidemiological studies, although a modest excess risk emerged in case-control studies, that added sugars, dietary glycemic index and glycemic load are associated with increased risk of colon cancer, independently from their effect on energy intake, overweight, obesity and diabetes, which are related to excess colon cancer risk.

Abstract
AIMS To update epidemiological data on alcohol and breast cancer, with special emphasis on light alcohol consumption, and to review mechanisms of alcohol mediated mammary carcinogenesis. METHODS For epidemiological data, in November 2011 we performed a literature search in various bibliographic databases, and we conducted a meta-analysis of data on light alcohol drinking. Relevant mechanistic studies were also reviewed to November 2011. RESULTS A significant increase of the order of 4% in the risk of breast cancer is already present at intakes of up to one alcoholic drink/day. Heavy alcohol consumption, defined as three or more drinks/day, is associated with an increased risk by 40-50%. This translates into up to 5% of breast cancers attributable to alcohol in northern Europe and North America for a total of approximately 50,000 alcohol-attributable cases of breast cancer worldwide. Up to 1-2% of breast cancers in Europe and North America are attributable to light drinking alone, given its larger prevalence in most female populations when compared with heavy drinking. Alcohol increases estrogen levels, and estrogens may exert its carcinogenic effect on breast tissue either via the ER or directly. Other mechanisms may include acetaldehyde, oxidative stress, epigenetic changes due to a disturbed methyl transfer and decreased retinoic acid concentrations associated with an altered cell cycle. CONCLUSIONS Women should not exceed one drink/day, and women at elevated risk for breast cancer should avoid alcohol or consume alcohol occasionally only.

Abstract
Please cite this paper as: Esposito et al. (2012) Impact of viral infections in children with community‐acquired pneumonia: results of a study of 17 respiratory viruses. Influenza and Other Respiratory Viruses DOI: 10.1111/j.1750‐2659.2012.00340.x. Background Little is known about the prevalence of viral infections in children with community‐acquired pneumonia (CAP). Objectives To describe the clinical and virological data collected from children with radiographically confirmed CAP in whom 17 respiratory viruses were sought in respiratory secretion samples during the acute phase of the disease. Patients and methods The study involved 592 children with radiographically confirmed CAP whose respiratory secretion samples were tested using the Luminex xTAG Respiratory Virus Panel Fast assay, which simultaneously detects influenza A virus, influenza B virus, respiratory syncytial virus (RSV)‐A and ‐B, parainfluenzavirus‐1, ‐2, ‐3, and ‐4, adenovirus, human metapneumovirus, coronaviruses 229E, NL63, OC43, and HKU1, enterovirus/rhinovirus, and bocavirus. A real‐time PCR assay was used to identify the rhinovirus in the enterovirus/rhinovirus‐positive samples. Results A total of 435 children (73·5%) were positive for at least one virus: the most frequently detected was RSV, which was found in 188 (31·7%), followed by rhinovirus (n = 144, 24·3%), bocavirus (n = 60, 10·1%), influenza viruses (n = 57, 9·6), and hMPV (n = 49, 8·2%). Viral co‐infections were found in 117 children (19·7% of the enrolled children; 26·9% of those with viral infections). Marginal differences were found between the infections owing to a single virus. Co‐infections showed radiographic evidence of alveolar pneumonia significantly more frequently than single infections (OR 1·72, 95% CI 1·05–2·81). Conclusions The findings of this study highlight the importance of respiratory viruses (mainly RSV and rhinovirus) in children with CAP and show the characteristics of both the single infections and co‐infections associated with the disease.

Abstract
PURPOSE To provide information on the role of the metabolic syndrome on prostate cancer risk. METHODS We examined data from a multicentric Italian case-control study. Cases were 1294 patients with incident, histologically confirmed prostate cancer. Controls were 1451 men hospitalized with acute, non-neoplastic conditions. All subjects were younger than 75 years. The metabolic syndrome was defined according to selected indicators of abdominal obesity, hypercholesterolemia, hypertension, and diabetes. We computed multivariate odds ratios (OR) and 95% confidence intervals (CI) using unconditional logistic regression. RESULTS Considering separate components of the metabolic syndrome, the ORs were 0.98 (95% CI, 0.72-1.34) for diabetes, 1.14 (95% CI, 0.96-1.36) for hypertension, 1.54 (95% CI, 1.26-1.89) for hypercholesterolemia, and 1.02 (95% CI, 0.86-1.21) for abdominal obesity. The OR of prostate cancer was 1.66 (95% CI, 1.22-2.28) in men with metabolic syndrome compared with those without. We found ORs of 1.02 (95% CI, 0.83-1.26) for men with one component of the metabolic syndrome, 1.12 (95% CI, 0.89-1.42) for two, 1.65 (95% CI, 1.15-2.36) for three, and 3.99 (95% CI, 1.03-15.4) for four compared with no components. CONCLUSIONS The metabolic syndrome was associated with the risk of prostate cancer in this population.
