Background: The programme for fiscal consolidation in Greece has led to income decrease and several changes in health policy. In this context, this study aims to assess how economic crisis affected unmet healthcare needs in Greece. Methods: Time series analysis was performed for the years 2004 through 2011 using the EU-SILC database. The dependent variable was the percentage of people who had medical needs but did not use healthcare services. Median income, unemployment and time period were used as independent variables. We also compared self-reported unmet healthcare needs drawn from a national survey conducted in pre-crisis 2006 with a similar survey from 2011 (after the onset of the crisis). A common questionnaire was used in both years to assess unmet healthcare needs, including year of survey, gender, age, health status, chronic disease, educational level, income, employment, health insurance status, and prefecture. The outcome of interest was unmet healthcare needs due to financial reasons. Ordinary least squares, as well as logistic regression analysis were conducted to analyze the results. Results: Unmet healthcare needs increased after the enactment of austerity measures, while the year of participation in the survey was significantly associated with unmet healthcare needs. Income, educational level, employment status, and having insurance, private or public, were also significant determinants of unmet healthcare needs due to financial reasons. Conclusions: The adverse economic environment has significantly affected unmet health needs. Therefore health policy actions and social policy measures are essential in order to mitigate the negative impact on access to healthcare services and health status.

The aim of this cohort study was to quantify the effect of alcohol on the risk of oral cancer in different strata of folate intake, controlling for known confounders.A cohort of 87,621 women in the Nurses' Health Study was followed up from 1980 to 2006, and 147 incident oral cancer cases were reported and confirmed. Data on alcohol intake and diet were obtained through self-reported food frequency questionnaires every 4 years. Cox proportional regression analysis was conducted to estimate the adjusted risk ratios (RR) and 95% confidence intervals (95% CI).When compared with nondrinkers, the adjusted RRs (95% CIs) for alcohol intake were 0.59 (0.39-0.87) for 0.1-14.9 g/d, 1.15 (0.67-1.97) for 15-29.9 g/d, and 1.92 (1.08-3.40) for ≥30 g/d. We observed a significant interaction between alcohol and folate intakes (P = 0.02). The cancer risk for subjects with high alcohol (≥30 g/d) and low folate (350 μg/d) intakes was significantly elevated (RR, 3.36; 95% CI, 1.57-7.20) as compared with nondrinkers with low folate intake. The risk associated with high alcohol intake (≥30 g/d) was reduced to 0.98 (0.35-2.70) in the high-folate (≥350 μg/d) group as compared with nondrinkers with high folate intake.High alcohol intake is associated with significantly increased oral cancer risk, especially in women with low folate intake.A significant interaction between alcohol and folate intakes seems to affect oral cancer risk in women, a finding with potential public health utility.

Bisphosphonates (BPs) effectively treat metastatic bone disease, hypercalcemia, and osteoporosis. BP exposure, however, may be associated with osteonecrosis of the jaw (ONJ). The aim of the present study was to estimate the magnitude of the association between intravenous (IV) BP exposure and ONJ, and to identify potential confounders.Using a case-control study design, the investigators identified and adjudicated a sample of cases with ONJ and matched them randomly with 5 controls per case. The controls were matched to cases on age, gender, cancer type, and date of cancer diagnosis. The medical records were abstracted and data on BP exposure, cancer therapy, and comorbidities were recorded. Statistical analyses were carried out using conditional logistic regression in Stata 9.0 (Stata Corp, College Station, TX).Thirty cases of ONJ were identified at Massachusetts General Hospital from February 2003 through February 2007. Zoledronate was found to confer significant risk toward development of ONJ (adjusted odds ratio = 31.8, P.05). Although a trend toward increased risk was noted for pamidronate, this association was not significant after controlling for zoledronate. Obesity and smoking were associated significantly with ONJ development, whereas oral BPs had no effect.In this study, cancer patients who had received zoledronate exhibited a significant 30-fold increase in their risk to develop ONJ. More studies are needed to elucidate the exact role of obesity and smoking in the development of ONJ, and the complex interactions of IV BPs with other chemotherapies during cancer treatment.
