Reconstructing prehistoric boats. A report on two experiments carried out during the first International Camp of Experimental. Archaeology, Toruń 2021

This article reports on two main archaeological experiments that were conducted during the first International Camp of Experimental Archaeology, which took place in August 2021 at Golub-Dobrzyń, close to Toruń, Poland. During the two weeks of this event, its participants, divided into two groups, carried out the reconstruction of two archaic boats: a dugout and a leather-covered boat known from ethnographic contexts mostly as the so-called skin-on-frame canoe. All work was carried out using exclusively techniques and tools known in the Stone and Bronze Ages. Also, this article presents a first discussion on the characteristics of use-wear traces created on the experimental tools

Curie-Skłodowskiej 9, Bydgoszcz, Poland Abstract Background: The guidelines for elderly recommend nutritional assessment in order to prevent malnutrition and make fast recovery after operation and mobilization possible. The ERAS protocol shortens the length of hospital stay and reduces the complication rate. Material and methods: A systematic review of published literature has been done for the factors reported to predict outcomes of enhanced recovery after surgery (ERAS) among the elderly patients. Results: The improvement of treatment effects must be supported by a multidisciplinary medical team involved in the whole process with holistic approach which reduces time of regeneration and cost of health care Conclusions: ERAS protocol implementation is highly beneficial for operated patients due to faster recovery and strong psychological support by providing information concerning the perioperative period and reducing stress caused by the surgery. However, must be supported by a team of professional medical staff. Key words: enhanced recovery after surgery, perioperative care, older peopl

What affects the risk of developing Alzheimer's disease? Overview of risk factors

Introduction: Alzheimer's disease is currently one of the key challenges of medicine, due to the growing number of cases every year, especially in developed countries. It is characterized by disorders of episodic memory and specific neuropathological changes. Knowledge of risk factors allows for early prevention of the disease and gives the opportunity to delay the appearance of symptoms. Among them are: genetic factors, diet, dietary supplements, cardiovascular system, education and social involvement, and traumatic brain injury (TBI). Material and Methods: The paper reviews literature using the EBSCO and Google Scholar databases. Articles have been analyzed using the keywords Alzheimer's disease, supplements, risk factors, oxidative stress, cardiovascular system, TBI. The article presents potential risk of health and social factors affecting the development of AD. Results: The results show that one of the main risk factors are genetic factors, e.g. mutations in the presynilin 1 and presynilin 2 genes. The effect of many factors is oxidative stress, which should be minimized by a diet rich in antioxidants, including vitamins C, E and β- carotene and from group B and additionally supplement it with vitamin D supplement. It is also very important to properly operate the blood-brain barrier transporters, e.g. GLUT1. Studies have shown that β-amyloid accumulation, characteristic of AD, was noted a few hours after the onset of TBI, especially among men. Psychological and social observations, which indicate lower risk of AD in case of mentally and socially active people, can not be overlooked. Conclusions: The factors presented in the article are very numerous, which indicates the fact that there are many disorders that may influence the development of Alzheimer's disease to a greater or lesser degree, however the most important are the genetic factors and antioxidant deficiencies causing oxidative stress. The search for new factors causing the growing incidence of AD is important not only for social reasons, but also for economic reasons, due to the very costly care of the patient

Iron levels, genes involved in iron metabolism and antioxidative processes and lung cancer incidence.

BackgroundLung cancer is the most common adult malignancy accounting for the largest proportion of cancer related deaths. Iron (Fe) is an essential trace element and is a component of several major metabolic pathways playing an important role in many physiological processes. In this study we evaluated the association between Fe concentration in serum, iron metabolism parameters and genetic variaton in 7 genes involved in iron metabolism and anti-oxidative processes with the incidence of lung cancer in Poland.Materials and methodsThe study included 200 lung cancer patients and 200 matched healthy control subjects. We analyzed serum iron concentration and iron metabolism parameters (TIBC, UIBC, serum ferritin and transferrin saturation), and genotyped seven variants in seven genes: HFE, TFR1, HAMP, TF, SOD2, CAT and GPX1.ResultsLung cancer patients compared to their matched controls had significantly higher mean serum iron level (p = 0.01), ferritin level (p = 0.007) and TIBC (p = 0.006). Analysis revealed that higher concentration of iron and ferritin (IVth quartile) compared to the lower concentration (Ist quartile) was associated with over 2-fold increased lung cancer incidence. We also found that higher transferrin saturation (p = 0.01) and lower TIBC (pConclusionsThe results of this case control study indicate that higher body iron represented by higher Fe and ferritin levels may be associated with lung cancer incidence. Rs10421768 in HAMP may be associated with about 3-times higher lung cancer risk. Higher Fe body content may be associated with better survival of lung cancer patients
