Cancer burden among HIV-positive persons in Nigeria: preliminary findings from the Nigerian AIDS-cancer match study
Background: Although Nigeria has a large HIV epidemic, the impact of HIV on cancer in Nigerians is unknown. Methods: We conducted a registry linkage study using a probabilistic matching algorithm among a cohort of HIV positive persons registered at health facilities where the Institute of Human Virology Nigeria (IHVN) provides HIV prevention and treatment services. Their data was linked to data from 2009 to 2012 in the Abuja Cancer Registry. Match compatible files with first name, last name, sex, date of birth and unique HIV cohort identification numbers were provided by each registry and used for the linkage analysis. We describe demographic characteristics of the HIV clients and compute Standardized Incidence Ratios (SIRs) to evaluate the association of various cancers with HIV infection. Results: Between 2005 and 2012, 17,826 persons living with HIV (PLWA) were registered at IHVN. Their median age (Interquartile range (IQR)) was 33 (27–40) years; 41% (7246/17826) were men and 59% (10580/17826) were women. From 2009 to 2012, 2,029 clients with invasive cancers were registered at the Abuja Cancer Registry. The median age (IQR) of the cancer clients was 45 (35–68) years. Among PLWA, 39 cancer cases were identified, 69% (27/39) were incident cancers and 31% (12/39) were prevalent cancers. The SIR (95% CI) for the AIDS Defining Cancers were 5.7 (4.1, 7.2) and 2.0 (0.4, 3.5), for Kaposi Sarcoma and Cervical Cancer respectively. Conclusion: The risk of Kaposi Sarcoma but not Cervical Cancer or Non-Hodgkin’s Lymphoma, was significantly increased among HIV positive persons, compared to the general population in Nigeria
Hepatitis C virus- related cryoglobulinemic vasculitis: A review of the role of the new direct antiviral agents (DAAs) therapy
Hepatitis C virus (HCV) infection affects about 70 million people worldwide. HCV is responsible for both hepatitis and extra-hepatic manifestations. Chronic infection has been shown to develop in about 70% of cases and can progress to cirrhosis or hepatocellular carcinoma. Ten percent of HCV patients may develop extra-hepatic manifestations, including mixed cryoglobulinemia (MC) and non-Hodgkin lymphomas. Many studies have demonstrated that, after antiviral therapy, MC can disappear along with HCV eradication. After the introduction of the new direct antiviral agents (DAAs), the combination of pegylated interferon and ribavirin has been abandoned. Several studies on new DAAs have reported remarkable 90% to 100% eradication rates, regardless of HCV genotype. Treatment with DAAs has comparable efficacy on viral eradication in patients with MC, but definite clinical improvements of vasculitis can be observed only in half the patients. On the contrary, the regression of renal disease and lympho-proliferative disorders, induced by HCV, appears to have a lower remission rate after viral eradication with DAAs and most cases need immunosuppressive treatments. In HCV related CV, the main clinical goal must be early eradication of HCV, to avoid organ complication and manifestation of lympho-proliferative diseases. This review focuses on the role of DAAs in treatment of HCV-related cryoglobulinemic vasculitis
Self-reported history of Pap-smear in HIV-positive women in Northern Italy: a cross-sectional study
<p>Abstract</p> <p>Background</p> <p>The incidence of invasive cervical cancer in HIV-positive women is higher than in the general population. There is evidence that HIV-positive women do not participate sufficiently in cervical cancer screening in Italy, where cervical cancer is more than 10-fold higher in women with AIDS than in the general population. The aim of the present study was to evaluate the history of Pap-smear in HIV-positive women in Italy in recent years. We also examined the sociodemographic, clinical, and organizational factors associated with adherence to cervical cancer screening.</p> <p>Methods</p> <p>A cross-sectional study was conducted between July 2006 and June 2007 in Emilia-Romagna region (Northern Italy). All HIV-positive women who received a follow-up visit in one of the 10 regional infectivology units were invited to participate. History of Pap-smear, including abnormal smears and subsequent treatment, was investigated through a self-administered anonymous questionnaire. The association between lack of Pap-smear in the year preceding the interview and selected characteristics was assessed by means of odds ratios (OR) and 95% confidence intervals adjusted for study centre and age.</p> <p>Results</p> <p>A total of 1,002 HIV-positive women were interviewed. Nine percent reported no history of Pap-smear, and 39% had no Pap-smear in the year prior to the date of questionnaire (last year). The lack of Pap-smear in the last year was significantly associated with age <35 years (OR = 1.4, compared to age ≥45 years), lower education level (OR = 1.3), first HIV-positive test in the last 2 years (OR = 1.4), and CD4 count <200 cells/μl (OR = 1.6). Conversely, when women were advised by a gynecologist rather than other health workers to undergo screening, it significantly increased adherence. Non-significantly higher proportions of lack of Pap-smear in the last year were found in women born in Central-Eastern Europe (OR = 1.8) and Africa (OR = 1.3). No difference in history of Pap-smear emerged by mode of HIV-acquisition or AIDS status.</p> <p>Three hundred five (34%) women reported a previous abnormal Pap-smear, and of the 178 (58%) referred for treatment, 97% complied.</p> <p>Conclusions</p> <p>In recent years the self-reported history of Pap-smear in HIV-positive women, in some public clinics in Italy, is higher than previously reported, but further efforts are required to make sure cervical cancer screening is accessible to all HIV-positive women.</p
Cigarette tar yield and risk of upper digestive tract cancers: case-control studies from Italy and Switzerland
BACKGROUND: Tobacco smoking is one of the main risk factors for oral, pharyngeal and oesophageal cancers in developed countries. Information on the role of the tar yield of cigarettes in upper digestive tract carcinogenesis is sparse and needs to be updated because the tar yield of cigarettes has steadily decreased over the last few decades. PATIENTS AND METHODS: We analysed two case-control studies, from Italy and Switzerland, conducted between 1992 and 1999, involving 749 cases of oral and pharyngeal cancer and 1770 controls, and 395 cases of squamous-cell oesophageal carcinoma and 1066 matched controls. Odds ratios (ORs) were estimated by unconditional multiple logistic regression models, including terms for age, sex, study centre, education and alcohol consumption. RESULTS: Based on the brand of cigarettes smoked for the longest time, the multivariate ORs for current smokers compared with never smokers were 6.1 for <20 mg and 9.8 for >or=20 mg tar for oral and pharyngeal neoplasms, and 4.8 and 5.4 for oesophageal cancer, respectively. For the cigarette brand smoked in the previous six months, the ORs for >or=10 mg compared with <10 mg were 1.9 for cancer of the oral cavity and pharynx and 1.8 for oesophageal cancer, after allowance for number of cigarettes and duration of smoking. CONCLUSIONS: The present study confirms the direct relationship between the tar yield of cigarettes and upper digestive tract neoplasms, and provides innovative information on lower tar cigarettes, which imply reduced risks compared with higher tar ones. However, significant excess risks were observed even in the lower tar category, thus giving unequivocal indications for stopping smoking as a priority for prevention of upper digestive tract neoplasms.

<![CDATA[Dual bronchodilator therapy is recommended for symptomatic patients with chronic obstructive pulmonary disease (COPD). There are limited data on effects of a combination of two long-acting bronchodilators on lung function including body plethysmography.
This multicentre, randomised, double-blind, single-dose, cross-over, placebo-controlled study evaluated efficacy and safety of the free combination of indacaterol maleate (IND) and glycopyrronium bromide (GLY) versus IND alone on spirometric and body plethysmography parameters, including inspiratory capacity (IC), forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), total lung capacity (TLC) and airway resistance (Raw) in moderate-to-severe COPD patients.
Seventy-eight patients with FEV1 % pred. (mean ± SD) 56 ± 13% were randomised. The combination of IND + GLY versus IND presented a numerically higher peak-IC (Δ = 0.076 L, 95% confidence interval [CI]: -0.010 - 0.161 L; p = 0.083), with a statistically significant difference in mean IC over 4 h (Δ = 0.054 L, 95%CI 0.022 - 0.086 L; p = 0.001). FEV1, FVC and Raw, but not TLC, were consistently significantly improved by IND + GLY compared to IND alone. Safety profiles of both treatments were comparable.
The free combination of IND + GLY improved lung function parameters as evaluated by spirometry and body plethysmography, with a similar safety profile compared to IND alone.

Elevated risks of death for diabetes mellitus and cardiovascular diseases in Italian AIDS cases
After the introduction of highly active antiretroviral therapies (HAART), an increased incidence of insulin resistance, diabetes mellitus (DM), and cardiovascular diseases has been described. The impact of such conditions on mortality in the post-HAART era has been also assessed in various modes in the literature. In this paper, we report on the death risks for DM, myocardial infarction, and chronic ischemic heart diseases that were investigated among 9662 Italian AIDS cases diagnosed between 1999 and 2005. Death certificates reporting DM, myocardial infarction, and chronic ischemic heart diseases were reviewed to identify the underlying cause of death, and to compare the observed numbers of deaths with the expected ones from the sex- and age-matched, general population of Italy. Person-years at risk of death were computed from date of AIDS diagnosis up to date of death or to December 31, 2006. Standardized mortality ratios (SMR) and their 95% confidence intervals (CI) were computed. DM and cardiovascular diseases were the cause of death for 43 out of 3101 deceased AIDS cases (i.e., 1.4% of all deaths). In comparison with the general population, the risks of death were 6.4-fold higher for DM (95% CI:3.5-10.8), 2.3-fold higher for myocardial infarction (95% CI:1.4-3.7) and 3.0 for chronic ischemic heart diseases (95% CI: 1.5-5.2)
Micronutrients and laryngeal cancer risk in Italy and Switzerland: a case-control study
OBJECTIVE: To investigate the relation between various micronutrients and laryngeal cancer risk. METHODS: A case-control study was conducted in Italy and Switzerland between 1992 and 2000. Cases were 527 patients with incident cancer of larynx, admitted to the major teaching and general hospitals of the study areas. Controls were 1297 subjects admitted for acute, non-neoplastic diseases to the same network of hospitals. Dietary habits were assessed using a validated food-frequency questionnaire. Odds ratios (OR) and their corresponding 95% confidence intervals (CI) were computed using multiple logistic regression. RESULTS: Significant inverse relations emerged between laryngeal cancer risk and intake of vitamin C (OR = 0.2, for the highest versus the lowest intake quintile; 95% CI: 0.2-0.4), beta-carotene (OR = 0.2; 95% CI: 0.2-0.4), alpha-carotene (OR = 0.3; 95% CI: 0.2-0.5), lutein/zeaxanthin (OR = 0.4; 95% CI: 0.3-0.6), vitamin E (OR = 0.4; 95% CI: 0.3-0.6), beta-criptoxanthin (OR = 0.4; 95% CI: 0.2-0.5), folic acid (OR = 0.4; 95% CI: 0.2-0.6), thiamin (OR = 0.4; 95% CI: 0.3-0.6), glutathione (OR = 0.5; 95% CI: 0.4-0.8), reduced glutathione (OR = 0.6; 95% CI: 0.4-0.8), vitamin B6 (OR = 0.6; 95% CI: 0.4-0.9) and potassium (OR = 0.6; 95% CI: 0.4-0.9). Direct associations were found with zinc (OR = 1.5; 95% CI: 1.0-2.2) and vitamin D (OR = 1.8; 95% CI: 1.2-2.6). Combining low intakes of vitamin C, carotene, vitamin E, and folate with heavy smoking and drinking led to ORs between 80 and 170. CONCLUSIONS: This study provides further support that, independently from smoking and alcohol consumption, the intake of several micronutrients, including selected antioxidants, is inversely related to laryngeal cancer risk.

<![CDATA[The way colleagues and supervisors acknowledge specific contribution and efforts of individuals is crucial for occupational mental health and well being. It contributes to improve the self image of employees and it gives a sense to the activities performed. We carried out a study about occupational health in police officers with a special emphasis on acknowledgment and reward. A questionnaire was sent to 1000 police officers working for a cantonal administration in Switzerland. In total, 695 participants answered the questionnaire. We used the French version of the Langner's questionnaire on psychiatric symptoms to identify cases characterized by potential mental health problems. Multiple choice items (6 modalities ranging from "not at all" to "tremendously") to measure acknowledgment were used. Answers were later dichotomized (low annoyance- high annoyance). Questions we used are: "Do you feel annoyed due to a lack of support and attention from your supervisors?" "Do you feel annoyed because the authorities (politics, judges, etc.) have a low consideration of your occupation?" "Do you feel annoyed due to a low appreciation by the public?" and "Do you feel annoyed due to a lack of acknowledgment by the hierarchy?". The score for psychiatric symptoms was high for 86 police officers for whom health might be at risk. Acknowledgment aspects associated with a high score for psychiatric symptoms are : high annoyance due to a lack of support and attention from supervisors (odds ratio [OR] 3.2, 95% confidence interval [CI] 2.0 to 5.1), high annoyance because authorities seems to have a low consideration for police officers (OR 2.7, 95% CI 1.7 to 4.3), high annoyance due to a low appreciation by the public (OR 1.8, 95% CI 1.2 to 2.9), and high annoyance due to a lack of acknowledgment by the hierarchy (OR 3.0, 95% CI 1.9 to 4.8). Preserving mental health in occupations characterized by high emotional demand is challenging. The results from our study suggest that appropriate acknowledgment might contribute to the prevention of mental health problems. Further research should address a potential causal relation of acknowledgment on mental health
