This study tried to clarify the ecological damage in the areas of sheep transhumance, after the regime change of 1989, in the South Carpathian Mts. of Romania. The number of sheep increased by a factor of ten per hectare in areas where transhumance was practiced in the South Carpathian Mountains. This was because the sheep cheese produced in this area became more popular and increased in price. Jina and Poiana Sibiului villages are located on the third peneplain (900-1000m a. s. l.) of the Southern Carpathian Mountains, which consists of crystalline schist of Precambrian origin. Soil erosion of common lands and water pollution caused by the transhumance of sheep is a serious problem in these villages. Soil erosion speeds were measured by comparing profiles on Sept. 20, 2003, and Sept. 6, 2004. Soil erosion in these transhumance areas progressed more during that one year. The bedrock is extremely hard and the recovery of soil and vegetation will probably be difficult over the short term. In Patârlagele, where soils were composed of Miocene marl, soil erosion was very prevalent and easily progressed. However, the recovery of soils and vegetation was faster than in Jina and Poiana Sibiului, because of the softer and younger mother rock. In Jina and Poiana Sibiului, the Roma and Bayash people have been washing wool in the creeks. The water was seriously polluted as a result. Results of a chemical analysis showed high sodium, potassium and bicarbonate levels after wool washing. It is recommended that in areas with soil erosion, sheep would not be allowed entry so as to protect nature. Wool washing should be done in plants, where polluted water can be treated before being discharged into natural.

The efficacy of direct current (DC) cardioversion before catheter ablation (CA) for persistent atrial fibrillation (PerAF) patients remains controversial. We hypothesized that maintenance of sinus rhythm (SR) by pre-ablation DC cardioversion may predict the outcome of CA in patients with PerAF. A total of 383 PerAF patients with no or mild symptoms (EHRA I/II) who had undergone DC cardioversion before CA (301 males, 65 ± 10 years old, mean atrial fibrillation (AF) duration: 25 ± 47 months) were retrospectively enrolled. Whether or not SR was maintained at least 24 hour after DC cardioversion, patients were divided into two groups, namely, the DC-SR group and DC-AF group, and then all were followed until AF recurrence after CA. After DC cardioversion, 281 (73%) patients were categorized into the DC-SR group, and 102 (27%) were categorized into the DC-AF group. A total of 195 patients underwent CA at an average of 83 (54-145) days after DC cardioversion, including 161 (83%) in the DC-SR group and 34 (17%) in the DC-AF group. During follow-up (median: 15 [10-25] months), the number of patients who were free from AF was significantly higher in the DC-SR group compared with the DC-AF group (61.5% versus 38.3%, P < 0.0001). Multivariate analysis revealed that the DC-SR group (hazard ratio [HR]: 0.45, 95% confidence interval [CI]: 0.21-0.99, P = 0.047) and age at first AF diagnosis (HR: 0.95, 95% CI: 0.91-1.00, P = 0.039) were the independent predictors for being AF-free after CA. In conclusion, the 24-hour rhythm outcome of pre-ablation DC cardioversion and age at first AF diagnosis may predict the recurrence of AF after CA in patients with PerAF.
