As metabolic and multiorgan distempers arising from alcohol and medicines abuse predispose to nutritional state disorders, a simple method of nutriture assessment of hospitalized intoxicated patients is searched in order to help to improve the treatment effects. One hundred and thirten patients hospitalized in the Department of Clinical Toxicology, including 65 chronic alcoholics and 48 intoxicated with medicines were examined for the nutritional state. The Mini Nutritional Assessment (MNA) method was applied parallely with anthropometry; the examination was performed twice: on admittance and on discharge of each patient. On the basis of anthropometry, the nutritional state of alcohol and medicines intoxicated patients was unsatisfactory in 76% of examined group, with the cases of malnutrition and risk of malnutrition obviously more prevalent than overnutrition, especially in the cases of alcohol abusers. Proportions of the subjects qualified to specific groups of nutriture were dependent on the method used for nutritional assessment, and the MNA method tended to overestimate the nutritional state when compared with anthropometry but did not regard the cases of overnutrition. The MNA has to be completed with selected anthropometric measures in order to be useful in nutriture assessment of young adults.
Malnutrition leading to growth failure is one of the main problems in maintainig children with chronic liver diseases. The pathogenesis of malnutrition is complex and includes reduced calorie intake, fat malabsorption, impaired protein metabolism and increased energy expenditure. The nutritional status is an important risk factor for survival post liver transplantation. Aggressive nutritional support with careful monitoring is essential, particularly where liver transplantation is considered. When the oral nutrition is inadequate, the enteral feeding with nocturnal intragastric tube should be started. In case of gastrointestinal intolerance, severe malnutrition and gastrointestinal bleeding, parenteral nutrition should be considered.
Na základě hodnocení výsledků rozsáhlé metaanalýzy zabývající se problematikou vztahu výživy a zdravotního stavu, Světová zdravotnická organizace zařadila výživu k šesti základním faktorům podílejících se na vzestupu prevalence neinfekčních nemocí hromadného výskytu. Nevhodná výživa a nedostatečný pohybová aktivita výrazným způsobem zvyšují riziko vzniku metabolických onemocnění. Správná výživa zahrnující potravinové doplňky zabezpečuje vhodný přívod základních živin, mikronutrientů, minerálů a vitaminů, pozitivně ovlivňuje zdraví na individuální i populační úrovni.
U ogromnej większości ludzi starszych, a mianowicie u tych, którzy mieszkają w domu problemy żywieniowe są raczej natury jakościowej niż ilościowej, przynajmniej w krajach uprzemysłowionych. Inna grupa ryzyka odznacza się niemalże przeciwnym problemem, na przykład większym zapotrzebowaniem na energię, a także na niezbędne składniki odżywcze. Niemożność zaspokojenia tego zapotrzebowania przyczyniła się do powstania koncepcji niedożywienia szpitalnego, która została zastosowana i opisana w kilku krajach. Wielu pacjentów, o których się mówi, że cierpią z powodu niedożywienia szpitalnego, faktycznie choruje z powodu niedożywienia spowodowanego chorobą podstawową. Jednak u wielu pacjentów szpitalnych etiologia niedożywienia jest wieloczynnikowa, z elementami zarówno szpitalnymi jak i chorobowymi. Ciężkie stany niedożywienia można łatwo zdiagnozować zestawem metod klinicznych i laboratoryjnych. Jednak przypadki z pogranicza wykryć jest trudno. Sama choroba może spowodować pogorszenie apetytu, zaburzenia żołądkowo-jelitowe, a nawet wymioty. Ponadto schorzeniom nowotworowym, a także innym stanom, towarzyszy zwiększenie metabolizmu oraz wysokie zapotrzebowanie na energię. Farmakoterapia może spowodować pogorszenie apetytu. Upośledzenie fizyczne lub/i umysłowe może zaburzyć spożywanie posiłków. Niedostateczna aktywność fizyczna jest przyczyną niskiego zapotrzebowania na energię, a tym samym powoduje trudności w uzyskaniu dostatecznego pokrycia zapotrzebowania na niezbędne składniki odżywcze. Nieodpowiednie otoczenie towarzyszące spożywaniu posiłków może być przyczyną niedostatecznego odżywienia. Niedożywienie może się zdarzyć także w przypadku złego stanu jamy ustnej oraz niedostatecznej wiedzy i zrozumienia problemów żywieniowych przez personel medyczny. W badaniach przeprowadzonych przez naszą grupę wykazano, że poprawa np. otoczenia towarzyszącego spożywaniu posiłków, a także wzbogacanie składnikami odżywczymi przyczynia się do poprawy stanu odżywienia tych pacjentów.
Background. In hospital patients suffering from adverse clinical and biochemical symptoms of malnutrition, it is often necessary to employ parenteral nutrition to avoid the body’s tissue becoming broken down by being metabolised. Thus, the patient’s welfare and survival can be supported throughout any periods of medical crisis. Two of the enzymes responsible for metabolising glycoconjugates are a-fucosidase (FUC) and p-glucuronidase (GLU), present in lysosomes. They release fucose or glucuronic acid from the non-reducing end of oligosaccharide chains. Objective. To determine the effect of parenteral nutrition administered to ill patients, on glycoconjugate metabolism, by measuring serum and urinary activities of FUC and GLU. Material and methods. Blood samples and the daily urine collection were taken from 23 patients’ who had been undergoing parenteral nutrition for either 5 or 10 days, as well as from a baseline sample. Enzyme activities in serum and urine were determined by the method of Zwierz et al. Results. Serum FUC activities were significantly lower after 10 days compared to 5, (p< 0.0172), whereas GLU activities were significantly lower after both 5 and 10 days, (p< 0.0007 and p< 0.0208 respectively), compared to levels before starting parenteral nutrition. GLU activities were however higher after 10 days than those after 5 days, (p< 0.0023). In urine, FUC activities were significantly decreased after 10 days compared to 5 days after starting parenteral nutrition, (p< 0.0245). Urine GLU activities were unaffected by parenteral nutrition nor was any effect seen on FUC or GLU activities when calculated per 1mg creatinine. Conclusions. Serum FUC and GLU activities can be used for assessing the effect of parenteral nutrition on glycoconjugate metabolism. The significant decreases of serum GLU activity observed after 5 and 10 days, may serve to indicate that the components of parental nutrition are appropriate and that the body has become suitably adapted to this form of nutrition.
Background. Nutritional disorders constitute a significant clinical problem in the 21st century. The problems of overweight and obesity concern not only adults, but are also increasingly affecting developing children. Material and methods. The study was conducted among parents of children aged 10-13 years. Based on the data obtained from questionnaires distributed to the parents, body mass index (BMI) and degree of nutrition was determined and the influence of socio-demographic factors on the nutritional status of children was analyzed. Results. This study found that approximately 16% of children aged 10-13 are categorized as overweight, and 26% are categorized as obese. Place of residence has a significant effect on the BMI of included children, with those living in a country being characterized by a significantly lower BMI compared to those living in a town or city (p=0.008). Children whose parents are overweight or obese are characterized by a higher BMI compared to children whose parents are not overweight or obese (p=0.001). Conclusions. This study shows that the presence of overweight or obesity in a parent is correlated with a higher BMI in their children. In addition, children living in the countryside have a significantly lower average BMI compared to children living in a town or city.
Background. Prevalence of malnutrition among hospitalized patients is a common issue increasing the morbidity and mortality rate. In response to the aforementioned problem the European Society for Clinical Nutrition and Metabolism (ESPEN) stated an action plan to fight malnutrition and created in 2004 the global health project named NutritionDay (nD) - a single-day, population based, standardized, multinational cross-sectional audit which is performed worldwide in hospitals and nursing homes. Objectives. To present selected NutritionDay (nD) results from Poland describing the nutritional situation of hospitalized patients in 2006 – 2012 compared to other countries participating in nD study. Material and Methods. Data were collected in nD study through voluntary participation all over the world during seven years - from 2006 to 2012. Data collection was performed on ward level by staff members and patients using standardized questionnaires. The data were analyzed by the Vienna coordinating centre using the Structured Query Language (“my SQL”) - an open source relational database management system as well as the Statistical Analysis System version 9.2 (SAS). Results. In Poland 2,830 patients were included in the study during a 7-year survey, while 5,597 units recruited 103,920 patients in the world (nD reference). About 45% of the patients had a weight loss within the last 3 months prior to admission (same for nD references); 58.34% reported a decrease in eating during last week (54.85% in case of nD references). Food intake at nD illustrated that 60.55% of the patients ate half to nothing of the served meal (58.37% in the case of nD references). For both Poland and other countries participated in audit at the time of detection of malnutrition on the half of hospital wards wasn’t reported any action aimed at combating this phenomenon. Conclusions. Malnutrition of hospitalized patients in Poland was found comparable to the rest of the world. These results reflects the fact that malnutrition is a common issue among hospitalized patients all over the world and it would be recommended to continue the action plan to fight against malnutrition commenced by the European Society for Clinical Nutrition and Metabolism (ESPEN) on international and national level.
Micronutrient deficiencies have increased over recent decades due to the general depreciation of the quality of poor people’s diet, both in developed and developing countries. The deficiencies of iron (Fe) and zinc (Zn) are a critical public health problem worldwide, with the negative impact on health, lifespan and productivity. Biofortification is an agricultural approach that can improve human nutrition on a global scale. Agronomic biofortification is considered a short-term and complementary strategy, but economic analyses suggest that genetic biofortification is the most effective strategy for increasing dietary Fe and Zn intakes of vulnerable populations. Enrichment of cereal grains by breeding is a high-priority area of research, and an effective strategy among other approaches, e.g, fortification, supplementation and food diversification. This review discusses the role of Fe and Zn in plant nutrition, the potential strategies for developing Fe and Zn biofortified crops and their importance in human nutrition.
Protein-energy malnutrition with muscle wasting occurs in a large proportion of patients with chronic renal failure and is, in addition to atherosclerosis, a strong risk factor for cardiovascular mortality in dialysis patients. There is evidence that a chronic inflammation with activation of C-reactive protein and proinfalammatory cytokines is associated with increased oxidative stress and endothelial dysfunction. Strong relations between malnutrition, inflammation and atherosclerosis in dialysis patients suggest the presence of a MIA (malnutrition, inflammation and atherosclerosis) syndrome, which is associated with high mortality rate. Thus, it could be speculated that suppression of the vicious cycle of malnutrition, inflammation and atherosclerosis would improve survival in dialysis patients.
Malnutrition is a common clinical problem in dialysis patients. So far the management of malnutrition in this population has not been fully successful. The aim of the study was to evaluate the efficacy and safety of use of megestrol acetate suspension in malnourished dialysis patients. Twenty-six hypoalbuminemic (albumin ≤ 3.8 g/dl) dialysis patients took 160 mg of megestrol acetate daily for a period of two months. Anthropometry (dry weight, body mass index) and biochemical measurements of nutrition (serum albumin, triglycerides, total cholesterol) and inflammation (hsCRP, IL-1β, IL-6) were performed on a monthly basis. The treatment led to a statistically significant increase (P < 0.05) in anthropometry and albumin concentration, with no statistically significant changes in total cholesterol, triglycerides and indices of inflammation. Side effects included overhydration, diarrhoea and hyperglycaemia. Thus, megestrol acetate may be an effective therapeutic agent in improving the nutritional status of carefully selected dialysis patients, while it might not mitigate inflammation. Because of the prevalent side effects it must be monitored closely.
