    Malnutrition is usually related to some diseases such as inflammatory bowel disease, chronic pancreatitis, chronic liver disease and malignant tumors. It is characterized by weight loss, protein deficiency, and deficit of specific nutrients. The aim was to estimate the prevalence of nutritional risk among 160 gastrointestinal patients by use of the Nutritional Risk Screening (NRS-2002) score at hospital admission and discharge. The patients stayed in the hospital between 5 and 15 days or longer. Results showed that 40% of patients at admission and 36.2% at discharge were malnourished. There were 53.1% of patients with recognized malnutrition at admission that received nutritional support, whereas at discharge 34.4% of patients at risk were not dietary supported. Malnourished patients were significantly older, had lower body mass index, longer hospital stay and higher rate of malignant diseases than properly nourished patients. Regular screening for malnutrition should be conveyed in hospitals as to provide appropriate dietary support for all patients at risk.Malnutricija se povezuje s nekim bolestima kao što su upalna bolest crijeva, kronični pankreatitis, kronična bolest jetre i zloćudni tumori. Kod malnutricije dolazi do gubitka težine, manjka proteina te nedostatka nekih specifičnih hranjivih tvari. Cilj ovoga rada bio je procijeniti učestalost nutritivnog rizika kod 160 gastroenteroloških bolesnika metodom procjene nutritivnog rizika (NRS-2002) pri prijmu i otpustu bolesnika. Bolesnici su boravili u bolnici između 5 i 15 dana ili duže. Rezultati su pokazali da je kod prijma u bolnicu 40%, a na otpustu 36,2% bolesnika bilo pothranjeno. Na prijmu je 53,1% pothranjenih bolesnika dobilo odgovarajuću nutritivnu potporu, dok 34,4% bolesnika nije dobilo takvu potporu pri otpustu iz bolnice. Pothranjeni bolesnici bili su značajno mlađi, imali su značajno niži indeks tjelesne mase, značajno su dulje boravili u bolnici te su češće bolovali od zloćudnih bolesti. Procjena nutritivnog rizika treba biti rutinska kako bi se osigurala odgovarajuća nutritivna potpora za sve bolesnike koji su u riziku od malnutricije

    Olive leaf extract (OLE) is used in traditional medicine as a food supplement and as an over-the-counter drug for a variety of its effects, including anti-inflammatory and anti-atherosclerotic ones. Mechanisms through which OLE could modulate these pathways in human vasculature remain largely unknown. Serum amyloid A (SAA) plays a causal role in atherosclerosis and cardiovascular diseases and induces pro-inflammatory and pro-adhesive responses in human coronary artery endothelial cells (HCAEC). Within this study we explored whether OLE can attenuate SAA-driven responses in HCAEC. HCAEC were treated with SAA (1,000 nM) and/or OLE (0.5 and 1 mg/ml). The expression of adhesion molecules VCAM-1 and E-selectin, matrix metalloproteinases (MMP2 and MMP9) and microRNA 146a, let-7e, and let-7g (involved in the regulation of inflammation) was determined by qPCR. The amount of secreted IL-6, IL-8, MIF, and GRO-alpha in cell culture supernatants was quantified by ELISA. Phosphorylation of NF-kappa B was assessed by Western blot and DNA damage was measured using the COMET assay. OLE decreased significantly released protein levels of IL-6 and IL-8, as well as mRNA expression of E-selectin in SAA-stimulated HCAEC and reduced MMP2 levels in unstimulated cells. Phosphorylation of NF-kappa B (p65) was upregulated in the presence of SAA, with OLE significantly attenuating this SAA-induced effect. OLE stabilized SAA-induced upregulation of microRNA-146a and let-7e in HCAEC, suggesting that OLE could fine-tune the SAA-driven activity of NF-kappa B by changing the microRNA networks in HCAEC. SAA induced DNA damage and worsened the oxidative DNA damage in HCAEC, whereas OLE protected HCAEC from SAA- and H2O2-driven DNA damage. OLE significantly attenuated certain pro-inflammatory and pro-adhesive responses and decreased DNA damage in HCAEC upon stimulation with SAA. The reversal of SAA-driven endothelial activation by OLE might contribute to its anti-inflammatory and anti-atherogenic effects in HCAEC

    Multipla skleroza (MS) je bolest središnjeg živčanog sustava koja se prezentira brojnim simptomima iz različitih funkcijskih cjelina toga sustava. Kako se posljednjih godina povećao broj dostupnih lijekova, ukazuje se potreba trajne provjere saznanja o dijagnostici i liječenju ove bolesti putem medicine temeljene na dokazima. Time se nameće i potreba kontinuiranog obnavljanja nacionalnih i međunarodnih smjernica, u našem slučaju, na razini regionalnih smjernica Europskog odbora za liječenje i istraživanje multiple skleroze (engl. ECTRIMS, European Committee of Treatment and Research in Multiple Sclerosis) i Europske neurološke akademije (engl. EAN, European Academy of Neurology) s ciljem omogućavanja najbolje medicinske terapije za svakog bolesnika, koja je temeljena na individualiziranom pristupu. Temelji novih smjernica su nedavno ažurirane EAN-ove preporuke za razvoj smjernica, koje su rezultat iscrpnog istraživanja literature do prosinca 2016. godine. S obzirom na rizik od sistemske pogreške, kvaliteta dokaza za svaki ishod bila je stupnjevana u četiri kategorije kako slijedi: vrlo visoka, visoka, niska i vrlo niska. S obzirom na kvalitetu dokaza te omjera rizika i dobrobiti preporukama je pridružena snažna i slaba jačina. Pozornost istraživanja bila je usmjerena na nekoliko najvažnijih pitanja, koja su obuhvaćala uspješnost liječenja, odgovor na primijenjenu terapiju, strategiju za prepoznavanje odgovarajućeg odgovora i sigurnost, te terapijsku strategiju liječenja multiple skleroze u trudnoći. Smjernicama su obuhvaćeni svi lijekovi koji modifi ciraju tijek bolesti, a koji su odobreni od strane Europske agencije za lijekove (engl. EMA, European Medicine Agency). U posebne skupine raspoređeni su bolesnici s klinički izoliranim sindromom koji ne ispunjavaju dijagnostičke kriterije za klinički defi nitivnu MS, dok su bolesnici s dokazanom MS podijeljeni s obzirom na različite kliničke podtipove MS-a sukladno važećim dijagnostičkim smjernicama.Multiple sclerosis (MS) affects the central nervous system (CNS) and presents by numerous symptoms from different CNS functional systems. As the number of available treatments has increased in recent years, the need has emerged for continuous evaluation on MS diagnosis and treatment based on evidence-based medicine. This implies the need for continuous renewal of national and international guidelines, in our case, based on the regional guidelines of the European Committee for Treatment and Research in Multiple Sclerosis and European Academy of Neurology (EAN) with the aim of providing the best medical therapy for each patient, based on an individualized approach. These new guidelines are based on the recently updated EAN recommendations that have been derived as the result of exhaustive literature research as of December 2016. Given the risk of system error, the quality of evidence for each outcome has been subdivided into four categories, as follows: very high, high, low and very low. Given the quality of evidence and the risk and benefit ratio, the recommendations are accompanied by strong and weak strength. The research was focused on several key issues, including treatment effectiveness, response to therapy applied, strategy for recognizing appropriate response and safety, and therapeutic strategy for MS treatment during pregnancy. The guidelines cover all medicines that modify the course of the disease and are approved by the European Medicines Agency. Patients with clinically isolated syndrome that do not meet diagnostic criteria for clinically definitive MS have been assigned to special groups while patients with proven MS are divided into different clinical subtypes of MS in accordance with valid diagnostic guidelines

    Background: Estimates of demographic metrics are crucial to assess levels and trends of population health outcomes. The profound impact of the COVID-19 pandemic on populations worldwide has underscored the need for timely estimates to understand this unprecedented event within the context of long-term population health trends. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 provides new demographic estimates for 204 countries and territories and 811 additional subnational locations from 1950 to 2021, with a particular emphasis on changes in mortality and life expectancy that occurred during the 2020–21 COVID-19 pandemic period. Methods: 22 223 data sources from vital registration, sample registration, surveys, censuses, and other sources were used to estimate mortality, with a subset of these sources used exclusively to estimate excess mortality due to the COVID-19 pandemic. 2026 data sources were used for population estimation. Additional sources were used to estimate migration; the effects of the HIV epidemic; and demographic discontinuities due to conflicts, famines, natural disasters, and pandemics, which are used as inputs for estimating mortality and population. Spatiotemporal Gaussian process regression (ST-GPR) was used to generate under-5 mortality rates, which synthesised 30 763 location-years of vital registration and sample registration data, 1365 surveys and censuses, and 80 other sources. ST-GPR was also used to estimate adult mortality (between ages 15 and 59 years) based on information from 31 642 location-years of vital registration and sample registration data, 355 surveys and censuses, and 24 other sources. Estimates of child and adult mortality rates were then used to generate life tables with a relational model life table system. For countries with large HIV epidemics, life tables were adjusted using independent estimates of HIV-specific mortality generated via an epidemiological analysis of HIV prevalence surveys, antenatal clinic serosurveillance, and other data sources. Excess mortality due to the COVID-19 pandemic in 2020 and 2021 was determined by subtracting observed all-cause mortality (adjusted for late registration and mortality anomalies) from the mortality expected in the absence of the pandemic. Expected mortality was calculated based on historical trends using an ensemble of models. In location-years where all-cause mortality data were unavailable, we estimated excess mortality rates using a regression model with covariates pertaining to the pandemic. Population size was computed using a Bayesian hierarchical cohort component model. Life expectancy was calculated using age-specific mortality rates and standard demographic methods. Uncertainty intervals (UIs) were calculated for every metric using the 25th and 975th ordered values from a 1000-draw posterior distribution. Findings: Global all-cause mortality followed two distinct patterns over the study period: age-standardised mortality rates declined between 1950 and 2019 (a 62·8% [95% UI 60·5–65·1] decline), and increased during the COVID-19 pandemic period (2020–21; 5·1% [0·9–9·6] increase). In contrast with the overall reverse in mortality trends during the pandemic period, child mortality continued to decline, with 4·66 million (3·98–5·50) global deaths in children younger than 5 years in 2021 compared with 5·21 million (4·50–6·01) in 2019. An estimated 131 million (126–137) people died globally from all causes in 2020 and 2021 combined, of which 15·9 million (14·7–17·2) were due to the COVID-19 pandemic (measured by excess mortality, which includes deaths directly due to SARS-CoV-2 infection and those indirectly due to other social, economic, or behavioural changes associated with the pandemic). Excess mortality rates exceeded 150 deaths per 100 000 population during at least one year of the pandemic in 80 countries and territories, whereas 20 nations had a negative excess mortality rate in 2020 or 2021, indicating that all-cause mortality in these countries was lower during the pandemic than expected based on historical trends. Between 1950 and 2021, global life expectancy at birth increased by 22·7 years (20·8–24·8), from 49·0 years (46·7–51·3) to 71·7 years (70·9–72·5). Global life expectancy at birth declined by 1·6 years (1·0–2·2) between 2019 and 2021, reversing historical trends. An increase in life expectancy was only observed in 32 (15·7%) of 204 countries and territories between 2019 and 2021. The global population reached 7·89 billion (7·67–8·13) people in 2021, by which time 56 of 204 countries and territories had peaked and subsequently populations have declined. The largest proportion of population growth between 2020 and 2021 was in sub-Saharan Africa (39·5% [28·4–52·7]) and south Asia (26·3% [9·0–44·7]). From 2000 to 2021, the ratio of the population aged 65 years and older to the population aged younger than 15 years increased in 188 (92·2%) of 204 nations. Interpretation: Global adult mortality rates markedly increased during the COVID-19 pandemic in 2020 and 2021, reversing past decreasing trends, while child mortality rates continued to decline, albeit more slowly than in earlier years. Although COVID-19 had a substantial impact on many demographic indicators during the first 2 years of the pandemic, overall global health progress over the 72 years evaluated has been profound, with considerable improvements in mortality and life expectancy. Additionally, we observed a deceleration of global population growth since 2017, despite steady or increasing growth in lower-income countries, combined with a continued global shift of population age structures towards older ages. These demographic changes will likely present future challenges to health systems, economies, and societies. The comprehensive demographic estimates reported here will enable researchers, policy makers, health practitioners, and other key stakeholders to better understand and address the profound changes that have occurred in the global health landscape following the first 2 years of the COVID-19 pandemic, and longer-term trends beyond the pandemic
