Opis: Izhodišča: McGillov model zdravstvene nege je celostni, sodelovalni pristop, ki poudarja aktivno vlogo pacienta, vključevanje bližnjih in krepitev psihosocialne podpore. Kljub uveljavljenosti v mednarodnem prostoru njegova uporaba v slovenski klinični praksi še ni bila raziskana. Namen raziskave je bil ovrednotiti, v kolikšni meri medicinske sestre na področju onkološke zdravstvene nege uporabljajo pristope McGillovega modela, ki vključujejo sodelovanje pacientov, vključevanje družinskih članov in krepitev psihosocialne podpore. Metode: V kvantitativni presečni raziskavi je bilo k sodelovanju povabljenih približno 400 medicinskih sester, zaposlenih na področju onkološke zdravstvene nege. Vprašalnik je pričelo izpolnjevati 166 oseb, od tega ga je popolnoma izpolnilo 126 (odzivnost 31,5 % glede na populacijo medicinskih sester zaposlenih na področju onkološke zdravstvene nege). Večina anketirancev je bila ženskega spola (77,8 %). Povprečna starost anketirancev je bila 37,71 leta (s = 8,07) s povprečno delovno dobo na področju onkološke zdravstvene nege 9,66 leta (s = 7,93). Analiza je temeljila le na popolnoma rešenih vprašalnikih. Podatke smo zbrali z novo razvito lestvico, ki temelji na McGillovem sodelovalnem modelu. Anketiranci so trditve ocenjevali na petstopenjski lestvici, ki meri pogostost izvajanja pristopov ali stopnjo strinjanja z izjavo. Izvedli smo eksploratorno in konfirmatorno faktorsko analizo, Wilcoxonove in Mann–Whitneyjeve teste ter Spearmanovo korelacijo. Rezultati: Faktorska analiza je potrdila tri konstrukte, ki pojasnjujejo 65,3 % skupne variance (KMO = 0,896; Bartlett p < 0,001). Empirične mediane vseh treh konstruktov so bile statistično značilno višje od teoretičnih (p < 0,001), kar pomeni, da so anketiranci poročali o uporabi pristopov McGillovega modela. Anketiranci z dostopom do pisnih protokolov ali organizacijsko podporo so dosegali višje rezultate (p < 0,001). Ugotovljene so bile zmerne do visoke pozitivne korelacije med uporabo pristopov in zaznavo izboljšanja oskrbe ter psihosocialnega stanja onkoloških pacientov (p < 0,001). Zaključek: Rezultati potrjujejo, da se v onkološki zdravstveni negi pogosto uporabljajo pristopi McGillovega modela, kar pozitivno sovpada z zaznanim izboljšanjem kakovosti oskrbe. Model ima potencial za širšo in bolj formalizirano implementacijo v klinično prakso.

Opis: Background and purposeThe development of athletic performance requires a detailed assessment of the relationship between maximal strength and the ability to express it explosively. Traditional tests one-repetition maximum do not differentiate the rate of force development, which led to the introduction of the Dynamic Strength Index, defined as the ratio between force in the countermovement jump and the isometric mid-thigh pull . The aim of this paper was to present the theoretical background, methodological approaches, and practical applications of Dynamic Strength Index in order to optimize training and prevent injuries.Materials and methodsDynamic Strength Index is calculated by measuring peak force in countermovement jump and isometric mid-thigh pull tests using a force plate. Standardization of protocols (body position, contraction duration, software processing) is essential for validity. Test–retest reliability is high (Intraclass Correlation Coefficient >0.90). Normative values vary by sport and playing position: for example, sprinters and jumpers often record Dynamic Strength Index values >0.80, while weightlifters usually show lower values (<0.60).ResultsFindings indicate that DSI is an effective tool for training individualization. Values below 0.60 suggest the need for plyometric and ballistic training, while values above 0.80 point to a focus on maximal strength development. The optimal range (0.60–0.80) reflects a balanced profile. DSI is also useful for longitudinal monitoring of adaptations, adjusting training loads, and identifying injury risks. However, variability in testing protocols, anthropometric differences, and software processing may limit its applicability and comparability across studies.ConclusionDynamic Strength Index is a valuable biomechanical indicator linking maximal and explosive strength, allowing precise programming of training and performance monitoring. Its use has already been established in elite sports, but full validation requires measurement standardization and the development of sport-specific normative databases. Future directions include phase-specific force analysis within contraction cycles, expanding testing protocols, and integrating digital platforms for automated analysis.

Opis: In recent years, artichokes have gained attention as functional foods due to their polyphenol content and health benefits. While Italian varieties have been widely studied, the Slovenian landrace “Strunjanska articoka” remains largely unexplored. This study compared “Strunjanska articoka” with two Italian varieties, “Romanesco” and “Violetto di Romagna”, assessing genetic profiles, chemical composition, antioxidant activity, and effects on lipid accumulation. The genetic analysis confirmed the uniqueness and clear differentiation of the landrace “Strunjanska articoka” from the two commercial varieties. Analysing the profiles of phenolic compounds in the leaf extracts of these morphologically different artichoke varieties underlines their unique phytochemical composition, which translates into different health benefits. “Romanesco” showed the highest free radical scavenging activity (EC50 = 100 µg/mL), followed by “Strunjanska articoka” (EC50 = 143 µg/mL), and “Violetto di Romagna” (EC50 = 160 µg/mL). Importantly, “Strunjanska articoka” demonstrated superior cytoprotective effects against oxidative stress in HepG2 and CCD112CoN cells. It also reduced lipid accumulation in HepG2 cells, along with “Violetto di Romagna,” whereas “Romanesco” did not. These findings justify further investigation into the potential therapeutic effects of “Strunjanska articoka” and support the rationale for its cultivation.

Opis: Age-related noncommunicable diseases are a major health burden in developed countries, with oxidative stress being a key contributing factor. This cross-sectional study aimed to test the hypothesis that redox status among 88 participants with a particular interest in nutrition and habitually following 4 popular dietary patterns (vegan, vegetarian, low-carbohydrate high-fat, and omnivorous), is similar, but correlates with diet quality. Dietary intake was assessed using food diaries, and venous blood samples were collected to measure serum total antioxidative capacity (TAC), bilirubin, nicotinamide adenine dinucleotide (NAD⁺)/reduced form of nicotinamide adenine dinucleotide (NADH) ratio, and sirtuin 1 concentration, and the expression of antioxidative enzymes in leukocytes. TAC and the NAD⁺/NADH ratio were higher in the vegan group compared with the vegetarian group, whereas bilirubin concentration was higher in the omnivorous compared with the low-carbohydrate high-fat group. Other differences between the dietary groups were not significant. NAD+/NADH ratio and sirtuin 1 were positively correlated with diet quality, assessed with the Healthy Eating Index. Correlation analysis between dietary variables and redox markers revealed only a few weak to moderate associations. However, a hierarchical regression model including age, gender, and dietary variables explained 19.8% of the variance in TAC, 21.2% of the variance in the NAD⁺/NADH ratio, and 44.3% of the variance in sirtuin 1 concentration. Therefore, in healthy, relatively young participants with appropriate energy intakes, endogenous mechanisms are able to compensate for oxidative stress to a similar extent, regardless of dietary pattern. Nonetheless, overall diet quality and food selection appear to play a meaningful role in redox balance.

Opis: Objective: This study investigates the relationship between a new anthropometric measure, the Body Shape Index (ABSI), and body composition and biochemical parameters in hemodialysis patients and, for the first time, the correlation between ABSI and muscle strength and function in these patients. Methods: A cross-sectional study was conducted on a sample of 80 patients who were regularly treated in the hemodialysis unit of a single medical center of the University Hospital of Ljubljana, Slovenia. General anthropometric parameters body mass index (BMI) and ABSI=(WC/(BMI2/3x height½) as well as body composition data (fat mass FM, fat-free mass FFM, fat-free mass index FFMI, skeletal muscle index SMI) were determined in 25 women (aged 74.5 ± 7.5 years) and 55 men (aged 70.1 ± 6.6 years) with overweight (25 kg/m2 ≤ BMI < 30 kg/m2) and obesity (BMI ≥ 30 kg/m2) by bioelectrical impedance analysis (BIA). Muscle strength was determined using a hand grip strength test, while muscle performance was assessed using the sit-to-stand test. Results: ABSI was significantly negatively associated with muscle strength, functional tests and SMI only in men. Based on the median ABSI value (0.090273 m11/6·kg−2/3 in women and 0.090893 m11/6·kg−2/3 in men), women with a higher ABSI had a significantly higher glucose concentration than those with a lower ABSI. Men with a lower ABSI obtained significantly better results in the hand grip test, sit-to-stand test and waist circumference (WC). In conclusion, our findings suggest an inverse association between ABSI and muscle strength and function in male hemodialysis patients, indicating that higher ABSI may reflect poorer physical condition in this population. Further longitudinal studies are needed to explore the clinical significance of this relationship.
