Irritable bowel syndrome (IBS) belongs to functional gastrointestinal disorders and is characterized by abdominal pain and change in stool consistency and/or bowel habits. Etiological factors include gastrointestinal peristalsis disturbances, visceral hypersensitivity, chronic inflammation of the mucous membrane, dysbacteremia, intestinal infections, psychosomatic and nutritional factors. Gastrointestinal motility disturbances in case of IBS are manifested by the inhibition of the intestinal passage, which favors the development of constipation or occurrence of diarrhea. the aim of the study was to evaluate IBS symptoms and demonstrate the relationship between physical activity and place of residence amongst Warsaw University students. material and methods. The study was conducted in march, 2014 using a specific questionnaire, amongst Warsaw University students. The study group comprised 120 female patients, aged between 19 and 27 years (M=23.43; SD=1.29). The chi-square test was used for analysis, p<0.05 was considered as statistically significant. Results. The BMI of investigated patients ranged between 16.30-31.22 kg/m 2 (M=21.27; SD=2.71). The majority of respondents (76.6%) weighed within the normal limits. Abdominal pain or discomfort occurred more frequently in the group of students who considered their physical activity as low. In case of respondents with a low physical activity bowel movement disorders and stool continence changes occurred more often, as compared to those with moderate physical activity. The most common symptom was rectal tenesmus, the least common-presence of mucous in the stool. Analysis showed that students with low physical activity were more frequently absent from school/work, due to abdominal symptoms. The respondents with moderate activity more often considered their abdominal symptoms, being associated with stress. conclusions. IBS symptoms are common amongst Warsaw University students. In case of respondents with low physical activity, abdominal pain or discomfort occurred more often. It has been demonstrated that diet and stress might contribute to the occurrence of abdominal symptoms, being evidence of IBS.

Introduction The metabolism of the body is a complicated process. The most important organ of the organism that affects the intensity of changes is the liver. An effective treatment method of primary and metastatic tumours is a partial resection of the organ. The analysis of changes in the body composition of patients undergoing this type of treatment allows identification of problems coexisting with the underlying disease. Aim To evaluate changes in the parameters of body composition and the amount of resting metabolism. Material and methods The study group consisted of 87 patients who underwent resection of changes in the liver or thermoablation of focal lesions during hospitalisation. Results Analysis of the data showed that the surgical intervention contributes to a statistically significant ( p < 0.05) decrease in the value of the phase angle. A significant increase was noted within the extra cellular water content. The amount of resting metabolism in the postoperative period did not differ significantly; however, there was an upward trend in women and a downward trend in men. Conclusions Surgical resection of lesions aimed at extending the survival of patients are performed more and more often, while the consequences of these operations are not sufficiently known. The adverse effect of resection treatments on body composition parameters, mainly imaged by decreasing the phase angle value, should be minimised. Effects on metabolism remain ambiguous because no significant changes have been demonstrated in the postoperative period.

Cholelithiasis in chronic HPN patients is a frequent phenomenon. It seems useful to perform prophylactic cholecystectomy during primary subtotal resection of the small intestine, because the risk of cholelithiasis in this group of patients is very high.

Introduction: Resection is an optimal way of treatment of hepatic tumors and metastasis from another organ. The operational injury may influence on patients body composition examined by bioelectrical impedance (BIA). Analysis of parameters may be helpful in identifying early changes indicating of deterioration in nutritional status. The aim of the study: was to assess changes in body composition of patients before and after resection of liver tumors and potential radiofrequency ablation of lesions. Material and methods: The study included a group of 50 patients of the Department of General, Gastroenterological and Oncological Surgery, Medical University of Warsaw, who were qualified for radical surgical treatment of tumors within the liver. Data on water content, fat, muscle and cell mass were analyzed. Results: Comparing data obtained from patients before and after intervention in the liver, statistically significant (p <0.05) loss of intracellular water, muscle mass, cell mass, as well as adipose tissue, was demonstrated. The phase angle value in these patients also significantly changed, decreasing by an average of 0.61°. On the other hand, the increase in content was noted in the case of extracellular water. Conclusions: Surgical intervention within the liver causes noticeable, unfavorable changes in the body composition, as evidenced by the reduction in the value of muscle mass, as well as cellular mass, resulting in a decrease in the phase angle. Bioelectric impedance is a suitable method for assessing changes in body composition of patients undergoing liver resection and is useful in clinical practice. It is advisable to conduct further research in the group of patients undergoing invasive treatment of the liver due to: an increasing number of such operations and centers where this type of surgical intervention is performed.

Background. It seems that one of the factors affecting the way of nutrition in Poland was the dietary habits of countries that in the late 18th century made partitions, ie. Russia, Prussia and Austria. Therefore, nutrition models in the areas of individual partitions have undergone significant changes. Objective. The aim of the study was to check whether after 85 years after regaining independence there were still differences in the way of feeding indigenous inhabitants of areas previously under Austrian, Prussian and Russian annexation. Material and methods. The data collected during the WOBASZ survey carried out in the years 2003-2005 were used for the analysis. Results. The greatest differences in the way of feeding were found in the area that was previously under the rule of Prussia. The nutrition model was still largely reminiscent of typical German cuisine. There was a large consumption of sausages and spreads, and small vegetables and fruit. Nutrition models in other areas were less characteristic. Conclusions. The way of feeding indigenous people living in areas that were once partitions of Poland is still diverse and similar to the cuisine of the occupying country. STRESZCZENIEWprowadzenie. Wydaje się, że jednym z czynników oddziałujących na sposób żywienia w Polsce były zwyczaje żywieniowe krajów, które w końcu XVIII wieku dokonały rozbiorów, tj. Rosji, Prus i Austrii. Dlatego modele żywienia na obszarach poszczególnych zaborów uległy istotnym zmianom. Cel. Celem badania było sprawdzenie czy po 85 latach po odzyskaniu niepodległości nadal istniały różnice w sposobie żywienia rdzennych mieszkańców obszarów będących wcześniej pod zaborem austriackim, pruskim oraz rosyjskim. Materiał i metody. Do przeprowadzonej analizy wykorzystano dane zebrane w toku badania WOBASZ przeprowadzonego w latach 2003-2005. Wyniki. Największe odrębności w sposobie żywienia stwierdzono na obszarze będącym wcześniej pod panowaniem Prus. Model żywienia nadal w dużej mierze przypominał typową kuchnię niemiecką. Duże było spożycie kiełbas i tłuszczów do smarowania pieczywa, a małe warzyw i owoców. Modele żywienia na pozostałych obszarach były mniej charakterystyczne. Wnioski. Sposób żywienia ludności tubylczej mieszkającej na terenach, które kiedyś stanowiły zabory polskie, jest wciąż zróżnicowany i podobny do kuchni okupującego kraju.Słowa kluczowe: spożycie żywności, populacja polska, zwyczaje żywieniowe

STRESZCZENIEWstęp. W warunkach polskich alkohol oraz kamica żółciowa są głównymi czynnikami rozwoju ostrego zapalenia trzustki (OZT), które z czasem może przejść w inną jednostkę chorobową określaną jako przewlekłe zapalenia trzustki (PZT). Stan zapalny trzustki może powodować poważne zaburzenia trawienia tłuszczów oraz gospodarki węglowodanowej. Nieleczone zapalenie trzustki może prowadzić do poważnych powikłań, a nawet do zgonu. Dlatego ważna jest wczesna diagnoza zapalenia trzustki oraz wdrożenie skutecznego leczenia. W rozwoju zapalenia trzustki ważną rolę odgrywa odpowiednia dieta, której przestrzeganie ma na celu złagodzenie objawów choroby, polepszenie komfortu życia oraz zapobiega występowaniu powikłań. Cel. Celem pracy była ocena nawyków żywieniowych chorych z ostrym i przewlekłym zapaleniem trzustki. Materiał i metody. W badaniu wzięło udział 31 osób, w tym 10 kobiet i 21 mężczyzn, w wieku od 20 do 57 lat, u których zdiagnozowano ostre lub przewlekłe zapalenie trzustki. Wyniki. U chorych na PZT najczęściej towarzyszącymi jednostkami chorobowymi były: cukrzyca, kamica żółciowa, zaburzenia lipidowe oraz choroby serca. W grupie tej na cukrzycę chorowało 75% kobiet i 36% mężczyzn. W grupie z OZT 80% kobiet i 82% mężczyzn w żywieniu stosowało tradycyjną kuchnię polską. Tylko 20% kobiet spożywało potrawy lekkostrawne, żaden z mężczyzn nie spożywał pokarmów lekkostrawnych. W grupie z OZT żywność typu fast food preferowało 18% mężczyzn. W grupie osób chorych na PZT 100% kobiet oraz 81,8% mężczyzn stosowało tradycyjną kuchnię polską. Wnioski. U większości chorych z OZT i PZT występuje nadwaga. Cukrzyca jest najczęstszą towarzyszącą jednostką chorobową wśród chorych na OZT i PZT. Zaleceń żywieniowych dotyczących diety ła-two strawnej z ograniczeniem tłuszczów przestrzega mniej więcej połowa badanych. Dominującą techniką kulinarną wykorzystywaną przez chorych z OZT i PZT jest smażenie. Większość chorych na OZT i PZT nie wykazuje chęci zmiany nawyków żywieniowych i rezygnacji ze szkodliwych używek (alkoholu i papierosów).SŁOWA KLUCZOWE: ostre zapalenie trzustki, przewlekłe zapalenia trzustki, żywienie. ABSTRACT Introduction.In Poland alcohol and gallstones are the main factors for the development of acute pancreatitis, which sometimes can become chronic pancreatitis. Infl ammation of the pancreas can cause serious digestive disorders of fat and carbohydrates. Untreated, pancreatitis may cause serious complications and even lead to death.That is why it is important to early diagnose pancreatitis and implement effective treatment. In the development of pancreatitis an important role plays proper diet, compliance with which aims to alleviate symptoms, improve quality of life and prevent complications. Aim. To assess the eating habits of patients with acute and chronic pancreatitis. Material and methods. The study involved 31 people, including 10 women and 21 men at the age of 20 to 57 years who were diagnosed with acute or chronic pancreatitis. Results. In patients with chronic pancreatitis usually associated disease...
