EFFECTS OF THE GLOBAL ECONOMIC AND JOBS CRISIS ON THE HEALTH STATUS OF THE ITALIAN AND SICILIAN POPULATIONS: FROM THE OCCUPATIONAL MEDICINE TO NOT OCCUPATIONAL MEDICINE?

The economic crisis that started in 2008 in many countries of the world, has resulted in the reduction of many jobs in all the regions of Italy, most especially in the Southern part of the Country. The employment difficulties experienced by both the unemployed and employed workers, experiencing increasingly precarious conditions, will inevitably result in a worsening of psycho-physical conditions of the population; especially as an increase in stress-related diseases. Aims: The aim of this study is to point-out the possible effects of the economic crisis on the health status of the population resident in Italy and Sicily, evaluating data from years preceding and following the year 2008. Methods: We have selected two populations: the first comprising the inhabitants of the Italian territory, the second comprising the inhabitants in the Sicilian territory. We evaluated official statistical data regarding demographics, information about lifestyles that can cause cardiovascular diseases, and also statistical data about job accidents and occupational diseases. We also investigated the use of antidepressant drugs, as indicators of psychological distress and metabolic diseases in the two populations. Results: Data analysis shows an overall increase of people migrating to foreign countries, increased unemployment for all age groups, with dramatic spikes in Sicily, and degenerating lifestyles associated with increasing numbers of subjects suffering from depression, diabetes and ischemic heart disease, although treatments and prognosis have improved. Work-related accidents only have been significantly reduced, while at the same time reports of occupational diseases increase. Conclusions: It is necessary to change economic policies and development throughout the country; especially in the Southern regions, in order to substantially improve the mental and physical health of the population

This study discuss home security and shows that "the house" is very rich of dangers. In fact housewives are exposed to various risk factors and have a high incidence of physical and mental disorders

Cromemia e cromuria: valori a confronto tra soggetti professionalmente esposti al cromo e popolazione generale

Aim of present study is the valutation and quantification of chromium in blood and urine. We compared 3 groups of persons formed by building workers, in particular masons, because cement contains potassium chromate that is dangerous for health, and by common people: urban population and outside the town population. In fact, exposure to CrVI risk is high for people who live near chromate industries. We maked a medical examination, blood and instrumental tests, chromium measuring in blood (recent exposure indicator) and urine (recent and previous indicator). Then we used statistical methods to estimate obtained values of blood and urine chromium among professional exposed people and common people. At the end we think that preventive measures in working environment reduced exposure to CrVI but environmental exposure (for example road dust from catalytic converter erosion, from brake lining erosion, cement dust and tobacco smoke), in the last years, has increased. So there are no difference between urban population and outside the town population and there are also no difference with professional exposed people for work prevention according to law in force, that let down professional risk using safe limits

Cardiovascular effects of occupational exposure to urban airborne pollution on a group of newsagents in the city of Palermo

Aims: To verify the possible correlation between exposure to airborne particulate matter the average size less than 10 μm (PM 10) of a group of newsagents working in kiosks in Palermo and evidence of carotid intimal thickening. Materials and methods: data were collected relating to environmental monitoring of airborne pollutants. We have selected a sample of newsagents, who were submitted to some clinical investigations, including the carotid echo-color doppler examination. Results: The results show no correlation between the location of the kiosks, and the presence of intimal thickening. Conclusion: Exposition to urban pollutants in Palermo is likely homogenous in the different areas and can be considered an ubiquitous atherogenic risk factor

Emerging Targeted Therapies for Castration-Resistant Prostate Cancer

Until recently, few therapeutic options were available for patients with castration-resistant prostate cancer (CRPC). Since 2010, four new molecules with a demonstrated benefit (sipuleucel-T, cabazitaxel, abiraterone, and denosumab) have been approved in this setting, and to-date several other agents are under investigation in clinical trials. The purpose of this review is to present an update of targeted therapies for CRPC. Presented data are obtained from literature and congress reports updated until December 2011. Targeted therapies in advanced phases of clinical development include novel androgen signaling inhibitors, inhibitors of alternative signaling pathways, anti-angiogenic agents, inhibitors that target the bone microenvironment, and immunotherapeutic agents. Radium-223 and MDV3100 demonstrated a survival advantage in phase III trials and the road for their introduction in clinical practice is rapidly ongoing. Results are also awaited for phase III studies currently underway or planned with new drugs given as monotherapy (TAK-700, cabozantinib, tasquinimod, PROSTVAC-VF, ipilimumab) or in combination with docetaxel (custirsen, aflibercept, dasatinib, zibotentan). The optimal timing, combination, and sequencing of emerging therapies remain unknown and require further investigation. Additionally, the identification of novel markers of response and resistance to these therapies may better individualize treatment for patients with CRPC

Polychlorinated Biphenyls and Their Hydroxylated Metabolites (OH-PCBs) in Pregnant Women from Eastern Slovakia

OBJECTIVE: Our aim in the present study was to characterize and quantify the levels of polychlorinated biphenyls (PCBs) and specific polychlorobiphenylol (OH-PCB) metabolites in maternal sera from women delivering in eastern Slovakia. DESIGN: During 2002–2004, blood samples were collected from women delivering in two Slovak locations: Michalovce district, where PCBs were formerly manufactured, and Svidnik and Stropkov districts, about 70 km north. PARTICIPANTS: A total of 762 and 341 pregnant women were sampled from Michalovce and Svidnik/Stropkov, respectively, and OH-PCBs were measured in 131 and 31. EVALUATION/MEASUREMENTS: We analyzed PCBs using gas chromatography (GC)/electron capture detection. OH-PCBs and pentachlorophenol (PCP) were determined as methyl derivatives using GC-electron capture negative ionization/mass spectrometry. We characterized distributions in the full cohort using inverse sampling weights. RESULTS: The concentrations of both PCBs and OH-PCB metabolites of Michalovce mothers were about two times higher than those of the Svidnik/Stropkov mothers (p < 0.001). The median weighted maternal serum levels of the sum of PCBs (∑PCBs) were 5.73 ng/g wet weight (Michalovce) and 2.82 ng/g wet weight (Svidnik/Stropkov). The median sum of OH-PCBs (∑OH-PCBs) was 0.55 ng/g wet weight in Michalovce mothers and 0.32 ng/g wet weight in Svidnik/Stropkov mothers. 4-OH-2,2′ ,3,4′ ,5,5′ ,6-Heptachlorobiphenyl (4-OH-CB187) was a primary metabolite, followed by 4-OH-2,2′ ,3,4′ ,5,5′ -hexachlorobiphenyl (4-OH-CB146). Only four PCB congeners—CBs 153, 138, 180, and 170—had higher concentrations than 4-OH-CB187 and 4-OH-CB146 (p < 0.001). The median ratio of the ∑OH-PCBs to the ∑PCBs was 0.10. CONCLUSIONS: Mothers residing in eastern Slovakia are still highly exposed to PCBs, and their body burdens of these pollutants and OH-PCB metabolites may pose a risk for adverse effects on health for themselves and their children

Prenatal and Postnatal Serum PCB Concentrations and Cochlear Function in Children at 45 Months of Age

Background: Some experimental and human data suggest that exposure to polychlorinated biphenyls (PCBs) may induce ototoxicity, though results of previous epidemiologic studies are mixed and generally focus on either prenatal or postnatal PCB concentrations exclusively. Objectives: Our aim was to evaluate the association between pre- and postnatal PCB concentrations in relation to cochlear status, assessed by distortion product otoacoustic emissions (DPOAEs), and to further clarify the critical periods in development where cochlear status may be most susceptible to PCBs. Methods: A total of 351 children from a birth cohort in eastern Slovakia underwent otoacoustic testing at 45 months of age. Maternal pregnancy, cord, and child 6-, 16-, and 45-month blood samples were collected and analyzed for PCB concentrations. At 45 months of age, DPOAEs were assessed at 11 frequencies in both ears. Multivariate, generalized linear models were used to estimate the associations between PCB concentrations at different ages and DPOAEs, adjusting for potential confounders. Results: Maternal and cord PCB-153 concentrations were not associated with DPOAEs at 45 months. Higher postnatal PCB concentrations at 6-, 16-, and 45-months of age were associated with lower (poorer) DPOAE amplitudes. When all postnatal PCB exposures were considered as an area-under-the-curve metric, an increase in PCB-153 concentration from the 25th to the 75th percentile was associated with a 1.6-dB SPL (sound pressure level) decrease in DPOAE amplitude (95% CI: –2.6, –0.5; p = 0.003). Conclusions: In this study, postnatal rather than maternal or cord PCB concentrations were associated with poorer performance on otoacoustic tests at age 45 months.

A possible role for nitric oxide in modulating the functional cyclosporine toxicity by arginine

A possible role for nitric oxide in modulating the functional cyclosporine toxicity by arginine. The renal damage consequent to cyclosporine A (CsA) administration ranges from hemodynamic alterations to irreversible chronic lesions. The initial vasoconstriction depends upon the imbalance between the various modulators of the renal vascular tone, among which the most powerful are endothelins and nitric oxide (NO). CsA could play a crucial role by inhibiting the Ca++/calmodulin-mediated activation of the constitutive NO synthase (NOS) isoform, which converts L-arginine (L-Arg) into NO and citrulline, with a 1:1 stoichiometry. To investigate the possibility of modulating CsA nephrotoxicity with L-Arg we studied six groups (G) of Lewis rats treated with daily gavage up to eight weeks: G1, CsA 40 mg/kg; G2, G1 plus L-Arg 300 mg/kg; G3, G2 plus the competitive inhibitor of NOS, NG-nitro-L-Arg (L-NNA); G4, L-Arg alone; G5, L-NNA alone; and G6, controls receiving vehicle alone. After eight weeks L-Arg treated rats were protected against the toxic effects of CsA [creatinine (Cr) values, G2, 0.62 ± 0.05 mg/dl vs. G1, 0.99 ± 0.16 mg/dl, P < 0.001; proteinuria (P), G2, 7.2 ± 1.02 mg/day vs. G1, 15.1 ± 1.9 mg/day, P < 0.01]. The administration of L-NNA abolished the protective effect of L-Arg (G3, Cr 1.23 ± 0.16 mg/dl; P 16.9 = 2.3; P < 0.02 and P < 0.005, respectively vs. G2). The levels of Cr in G2 rats were superimposable to control groups. The NOS activity, evaluated by measuring [3H]citrulline formation from [3H]L-Arg in kidney homogenates, was blocked by L-NNA in G5 (0.019 ± 0.009 pmol/min/mg proteins vs. G6 0.047 ± 0.002, P < 0.01). NOS activity was significantly increased versus controls in G1 (0.110 ± 0.032, P < 0.01) and G2 (0.088 ± 0.009, P < 0.02), while L-NNA reversed this phenomenon (G3, 0.052 ± 0.03). The expression of mRNA encoding for cNOS and iNOS was only slightly increased in CsA-treated rats. We suggest that CsA treatment increases NOS activity in the kidney by a mechanism which does not require a de novo synthesis of the enzyme. Such an increase, that may be devoted to counterbalance the vasoconstrictive effects of the drug, is unable to reduce the toxic effect of CsA in the absence of exogenous L-Arg. Administration of L-Arg is likely to reduce CsA nephrotoxicity by accomplishing the higher request of activated NOS for its substrate, thus potentiating NO synthesis in the kidney.

Years of life that could be saved from prevention of hepatocellular carcinoma

BACKGROUND: Hepatocellular carcinoma (HCC) causes premature death and loss of life expectancy worldwide. Its primary and secondary prevention can result in a significant number of years of life saved. AIM: To assess how many years of life are lost after HCC diagnosis. METHODS: Data from 5346 patients with first HCC diagnosis were used to estimate lifespan and number of years of life lost after tumour onset, using a semi-parametric extrapolation having as reference an age-, sex- and year-of-onset-matched population derived from national life tables. RESULTS: Between 1986 and 2014, HCC lead to an average of 11.5 years-of-life lost for each patient. The youngest age-quartile group (18-61 years) had the highest number of years-of-life lost, representing approximately 41% of the overall benefit obtainable from prevention. Advancements in HCC management have progressively reduced the number of years-of-life lost from 12.6 years in 1986-1999, to 10.7 in 2000-2006 and 7.4 years in 2007-2014. Currently, an HCC diagnosis when a single tumour <2 cm results in 3.7 years-of-life lost while the diagnosis when a single tumour 65 2 cm or 2/3 nodules still within the Milan criteria, results in 5.0 years-of-life lost, representing the loss of only approximately 5.5% and 7.2%, respectively, of the entire lifespan from birth. CONCLUSIONS: Hepatocellular carcinoma occurrence results in the loss of a considerable number of years-of-life, especially for younger patients. In recent years, the increased possibility of effectively treating this tumour has improved life expectancy, thus reducing years-of-life lost
