To analyze the trend of lower extremity major amputations (MA) among patients with type 2 diabetes mellitus (T2DM) in the Regions of Spain from year 2001 until 2015.
Descriptive study of 40,392 MA. ...Data were obtained from the national hospital discharge database in patients with T2DM. The incidence rate was calculated in each Region, in addition to the incidence ratios (IR) between annual incidence and incidence of the year 2001. The length of hospital stay and mortality risks were analyzed using regression models adjusted for sex, age and smoking.
The major amputations incidence rate per 100,000 person-years was 0.48 in Spain; Canary Islands showed the highest incidence (0.81). The trend was a slight decrease or stability of the incidence in all Regions except in the Canary Islands (IR
= 2.0 CI95% = 1.5, 2.6) and in Madrid (IR
= 0.1 CI95% = 0.1, 0.2). Mortality after major amputations was 10% in Spain; Cantabria suffered the highest risk of death 1.7 (CI95% = 1.4; 2.1), p < 0.001 and La Rioja the lowest risk (0.5 CI95% = 0.2; 0.9; p = 0.026). The longest hospital stay was registered in the Canary Islands (CI95% = 11.4;13.3, p < 0.001), and the shortest in the Valencian Community (CI95% = - 7.3; - 5.8), p < 0.001).
MA in T2DM followed a growing trend in the Canary Islands, which diverged from the downward trend in Spain. The variability of mortality and hospital stay, suggest to review the clinical management in some Regions. Sudden incidence decrease in Madrid suggests checking the record procedures of hospital discharges.

Free-Living Amoebae (FLA) are widely distributed protozoa, which contain some groups considered as pathogenic microorganisms. These members are able to produce several opportunistic diseases ...including epithelial disorders, such as keratitis and fatal encephalitis. Even though they have been reported in numerous sources, such as soils, dust and water, there is no legislation related to the presence of these protozoa in soil-related environments worldwide. Therefore, there are no established prevention or disinfection protocols to advise the population regarding FLA infections or eliminate these microorganisms from human-related environments to date. Acanthamoeba spp. are the most common FLA isolated in soil samples, which is also the most common genera found in clinical cases. Thus, the aim of the present study was to evaluate the presence of potentially pathogenic FLA in human-related soil samples of Santiago Island, Cabo Verde. A total of 26 soil samples were seeded in non-nutrient agar plates (2%), incubated at 26 °C, and monitored daily to evaluate the presence of FLA. DNA was extracted from those plates on which there was suspected FLA growth, and PCR amplification of the 18S rRNA gene was carried out. A total of 17 from the 26 analysed samples were positive for FLA, where Acanthamoeba is the most abundant isolated genus (14/17; 82.4%), with the T4 genotype being the most common (13/14; 92.9%), followed by the T5 genotype, A. lenticulata (1/14; 7.1%). Moreover, Vermamoeba vermiformis, Stenamoeba dejonckheerei and Vannella pentlandi were isolated in three other samples. To the best of our knowledge, this is the first report of FLA presence in Cape Verde and the first report of V. vermiformis in beach sand worldwide.
Despite the Naegleria genus being isolated from different natural environments such as water, soil, and air, not all Naegleria species are capable of causing infections in humans, and they are ...capable of completing their life cycle in environmental niches. However, the presence of this genus may suggest the existence of one of the highly pathogenic free-living amoeba (FLA) species: Naegleria fowleri or the brain-eating amoeba. This facultative parasitic protozoon represents a risk to public health, mainly related to domestic and agricultural waters. In this research, our main objective was to determine the existence of pathogenic protozoa in the Santa Cruz wastewater treatment plant, Santiago Island. Using 5 L of water we confirmed the presence of potentially pathogenic Naegleria australiensis, being the first report on Naegleria species in Cape Verde. This fact demonstrates the low efficiency in the treatment of wastewater and, consequently, a potential threat to public health. Nevertheless, more studies will be needed for the prevention and control of possible infections in this Macaronesian country.
Free-living amoebae (FLA) are protozoa which have been reported in different countries worldwide from diverse sources (water, soil, dust, air), contributing to the environmental microbiological ...contamination. Most of the FLA species present a life cycle with two different phases: an active vegetative and physiologically form named trophozoite, and an extremely resistant phase called cyst.

have been reported not only as causal agents of several opportunistic diseases including fatal encephalitis or epithelial disorders, but also as capable to favour the intracellular survival of common pathogenic bacteria, which could avoid the typical water disinfection systems, non-effective against FLAs cysts. Even though Santiago Island possesses high levels of humidity compared to the rest of the archipelago of Cape Verde, the water resources are scarce. Therefore, it is important to carry out proper microbiological quality controls, which currently do not contemplate the FLA presence in most of the countries. In the present work, we have reported the presence of

Vannella

Vermamoeba vermiformis
(7.7%) and the recently discovered
Stenamoeba dejonckheerei
