Temporal trends in stroke incidence and case-fatality rates in Arcadia, Greece: A sequential, prospective, population-based study.

BACKGROUND: Stroke incidence and case-fatality are reported to decline in high-income countries during the last decades. Epidemiological studies are important for health services to organize prevention and treatment strategies. AIMS: The aim of this population-based study was to determine temporal trends of stroke incidence and case-fatality rates of first-ever stroke in Arcadia, a prefecture in southern Greece. METHODS: All first-ever stroke cases in the Arcadia prefecture were ascertained using the same standard criteria and multiple overlapping sources in three study periods: from November 1993 to October 1995; 2004; and 2015-2016. Crude and age-adjusted to European population incidence rates were compared using Poisson regression. Twenty-eight days case fatality rates were estimated and compared using the same method. RESULTS: In total, 1315 patients with first-ever stroke were identified. The age-standardized incidence to the European population was 252 per 100,000 person-years (95% CI 231-239) in 1993/1995, 252 (95% CI 223-286) in 2004, and 211 (192-232) in 2015/2016. The overall age- and sex-adjusted incidence rates fell by 16% (incidence rates ratio 0.84, 95% CI: 0.72-0.97). Similarly, 28-day case-fatality rate decreased by 28% (case fatality rate ratio = 0.72, 95% CI: 0.58-0.90). CONCLUSIONS: This population-based study reports a significant decline in stroke incidence and mortality rates in southern Greece between 1993 and 2016.

Lung cancer, treatment and nutritional status.

Lung cancer is often diagnosed at inoperable advanced stages, and most patients exhibit cancer cachexia. The nutritional status of patients has been previously observed to serve a key role in cancer survival and cancer surgery. The aim of the current study was to collect information regarding the treatment of patients and associate them with different nutritional measurements. A total of 82 patients with non-small cell lung cancer were included in the present study. Several parameters were assessed, such as body mass index (BMI), Mediterranian diet score, number of years spent smoking, basic metabolsim (RMR; kcal/day), VO2 (ml/min), ventilation (lt/min) and physical activity. All the aforementioned parameters were associated with patient treatment, nutritional status and survival. Two-way ANOVA was conducted and pairwise group mean differences were tested using Fisher's LSD and Tukey tests. Normality and variance homogeneity was checked in all cases. The results revealed that RMR and oxygen consumption were negatively affected by the survival status of patients (P=0.012 and P=0.043, respectively). The mean fat difference was higher in patients treated with immunotherapy, and lower in those treated with chemotherapy in addition to immunotherapy, as demonstrated by Tukey comparisons. The survival of 25 patients were affected by the treatment they received (P=0.006). Chemotherapy administered in addition to immunotherapy prolonged patient life almost two-fold when compared with the individual effects of the two treatments, which became equal according to Fisher's LSD comparisons. In conclusion, the nutritional status of patients was associated with the administration of chemotherapy in addition to immunotherapy, and patient survival. Increased metabolism and fat mass were also associated with prolonged survival.
