Recenzja: Państwo a społeczeństwo. Wizje wspólnot niemieckich od oświecenia do okresu restauracji. Wybór i opracowanie Tadeusz Namowicz, Wydawnictwo Poznańskie, Poznań 2001, ss. 605. Poznańska Biblioteka Niemiecka, pod redakcją Huberta Orłowskiego i Christopha Kleßmanna, tom. 13
Poznańska Biblioteka Niemiecka, której kolejne tomy ukazują się od 1996 roku przy wsparciu finansowym Stiftung für deutsch-polnische Zusammenarbeit, została już dostrzeżona przez czytelników, i jest ważnym zjawiskiem w polskim edytorstwie. Tom trzynasty - poprzednie dotyczyły problemów kultury i historii XIX i XX wieku - ma charakter bardziej historyczny, cofa nas bowiem do czasów szczególnie ważnych dla kształtowania się myślenia Niemców o państwie i narodzie, mianowicie do końca XVIII i początku XIX wieku. Tom zawiera 34 teksty 22 autorów (niektórzy są reprezentowani przez kilka swoich tekstów), obszerne wprowadzenie pióra Tadeusza Namowicza pt. „Naród niemiecki - wpólnota ontycznie niewyobrażalna” oraz noty biograficzne. Całość zamyka wykaz bibliograficzny prac poświęconych zarówno analizom pojęć narodu, państwa narodowego i nacjonalizmu oraz historii Niemiec z tego punktu widzenia. Zwraca uwagę ogromna ilość nowej literatury niemieckiej poświęconej problematyce narodu i nacjonalizmu, a pochodzącej z lat 90-tych: w istocie, problematyka narodowa odżyła w Niemczech, co wiąże się z próbą poszukiwania innego spoiwa niemieckiej świadomości narodowej niż Verfassungspatriotismus, którego zasadniczą podstawą jest przywiązanie do niemieckiej liberalno-demokratycznej konstytucji z 1949 roku.

Jako edycja wspólna Towarzystwa Naukowego w Olsztynie i Ośrodka Badań Naukowych im. W. Kętrzyńskiego ukazała się książka Bohdana Łukaszewicza o Wojskowym Sądzie Rejonowym w Olsztynie, obejmująca cały okres jego działalności: od powołania tego typu sądów na początku 1946 r. do wiosny 1955 r., kiedy je zlikwidowano. Autor jest znanym historykiem, badaczem penetrującym historię najnowszą zwłaszcza Warmii i Mazur, ale dotychczas nie wkraczającym na obszar dziejów wymiaru sprawiedliwości. Trafność podjęcia tematu z zakresu wymiaru sprawiedliwości w obszarze prawa karnego w czasach stalinowsko-bierutowskich jest oczywista i z tej racji książkę powitać należy z zainteresowaniem. Waga tematu jest tym większa, że w okresie do kwietnia 1955 r. właśnie sądy wojskowe zostały przez nową władzę postawione na pierwszej „linii walki” ze stanowiącą zdecydowaną większość narodu opozycją polityczną; to głównie sądy wojskowe realizowany „funkcję dławienia oporu wroga klasowego” pod szyldem wymierzania sprawiedliwości w majestacie prawa.

Prawna regulacja wychodźstwa na ziemiach polskich pod panowaniem austriackim w latach 1832-1914
Authors: Kowalski Grzegorz
Published: January 2024

La réglementation juridique de l’émigration dans le XIX siècle en Autriche évoluait progressivement. En 1832 a été emis le brevet sur l’émigration selon lequel la reconnaissance d’une personne pour un émigré dependait de l’accomplissement de deux prémisses, primo: l’abandon réel des frontières du pays, secundo: l’intention de ne jamais revenir pour s’établir dans la monarchie. Le brevet distinguait l’émigration autorisée, effectuée avec l’accord des autorités ainsi que l’émigration non autorisée, qui entraînait de graves conséquences, entre autre la confiscation des biens. La privation de la nationalité était toujours le resultat de l’émigration. Pendant le „Printemps des Peuples” les demarches, ayant pour but l’augmentation des libertés des sujets en matière d’émigration, ont été entreprises à travers de convenables normes constitutionnelles. Cependant le retour vers l’absolutisme, manifesté par l’abrogation de la Constitution en vigueur a anéanti ces démarches. Ce n’est que dans la loi fondamentale du 1867, étant un des éléments de la Constitution de la monarchie concernant les droits universels des citoyens, que la liberté totale d’émigration a été introduite. Cette liberté était limitée uniquement par l’obligation militaire (art. 4 §§ 3 et 4). A partir de ce moment-là le citoyen autrichien au cas ou il quitterait la frontière du pays n’était pas responsable de la violation des normes de l’émigration, car aucune norme do cegenre n’existait pas. L’unique responsabilité pénale dans ce cas, était liée à l’infraction de l’accomplissement des lois concernants le service militaire. Dans les lois militaires de 1868, 1889 et de 1912 une catégorie de „fuite d’apparat”, avec les conséquences sous forme de peines d’amendes, peines en liberte et la prolongation du service militaire a été introduite. L’attitude de l’état vis-à-vis du problème de l’émigration, basée sur les normes de la Constitution de 1867, n’a pas changée même à la veille de l’éclat de la Première Guerre Mondiale. Cela a été confirmé par un communiqué spécial adressé aux citoyens de la Galicie par la régence en 1914. Les questions administratives concernantes les passeports et les certificats d’émigration, constituant la preuve de la nationalité autrichienne, s’ajouttent au problème de la réglementation juridique de l’émigration. Les certificats étaient delivrés à la demande de la partie interessée car dans certains pays l’acquisition d’une nouvelle nationalité nécessitait le renoncement à la nationalité précédente. A partir de 1865 celui qui franchissait la frontière pouvait, mais ne devait pas, être soumis à un contrôle de passeport par des services autrichiens de la frontière. Cela a été la preuve de la libération progressive des normes de la liberté de l’émigration.
Koncepcja stosunków Państwo – Kościół w świetle wypowiedzi biskupów polskich w latach 1989-1997
Authors: Borecki Paweł
Published: January 2024

Après l’an 1989 en Pologne, c’est surtout l’Église Catholique qui formait les relations entre l’État et les confessions religieuses. Dans les années 1989-1997, le développement institutionel de l’Église s’affrontait à la diversité du point de vue sur la vie qui se manifestait au sein de la population. Le catholicisme était considéré surtout comme un élément de la tradition culturelle. En ce qui concerne des relations entre l'Église, la position des évêques polonais a été déterminé par stéreotypes et des préjugés formés au temps de la Pologne Populaire. L’Episcopat polonais réjetait le système de la séparation de l’État et des confessions religieuses, y compris les éléments qui ont été acceptés par le Saint Siège à la seconde moitié du XXe siècle. En Pologne, l’Église catholique n’a pas reçu l’enseignement du Concile de Vatican II en son entier. Les évêques polonais se referaient souvent aux principes de la doctrine catholique du XIXe et celle de la première moitié du XXe siècle. C’était une régression par rapport à la période après la quand l’Episcopat reconnaissait successivement les éléments choisis de la séparation. On opposait l’interprétation libérale de ceux-ci aux pratiques totalitaires des gouvernants. Au temps des années 1990-1993, la vision théocratique de l’État était bien visible dans les déclarations publiques des évêques, La révision de celle-ci a abouti en liaison avec les débats publiques sur la ratification du concordat. Il est arrivé à l’affirmation du principe de l’autonomie et celui de l’indépendance de l’Église vis-à-vis de l’État, à la reconnaissance de égalité en loi de toutes les confessions ainsi qu’ à l’approbation non-conséquente du principe de la néutralité de l’État dans les affaires religieuses. Dans les années 1989-1997 en liaison avec les débats sur le modèle des relations entre l’État et l’Église, parmi les évêques polonais se sont formés deux fractions. Celle traditionelle a cultivé les idéaux de l’enseignement traditionnel de l’Église sur l’État. L’autre moderé se réferait à la position du Vaticanum Secundum.
Exploring the Behaviours of Small Business Entrepreneurs in the Gastro-Dining Industry: Risks, Relationships and Gourmet Chefs in Action
Authors: Atılgan Özgür , Berber Aykut , Uyargil Cavide
Published: January 2024

A growing number of chefs are setting up their own businesses to offer a gastro-dining experience in places without an extensive gastro-dining tradition. In this context, our purpose is to explore the behaviours of entrepreneurs of small businesses in the newly developing Turkish gastro-dining market. We adopted a qualitative research design to gain insight into the perceptions of ten entrepreneurs. Our findings demonstrate that the participants’ entrepreneurial behaviour can be explained through effectuation logic. This manifests itself through control over consumption, learning and improvising within the flow of life as well as the exchange of informal and positive relationships with stakeholders. Furthermore, we discovered that those entrepreneurs with gastronomy training also exhibited entrepreneurial behaviour in terms of aiming to become a brand, with a causation logic along with effectuation.
Hypothyroxinemia and weight velocity in preterm infants
Authors: Zibitt Meira , Ange Brittany , Wynter Zanna , Mundy Cynthia , Herrmann Steve , Stansfield Brian K.
Published: January 2024

Objectives

Hypothyroxinemia of prematurity (HOP) is characterized by low free thyroxine (FT4) associated with low or normal thyroid stimulating hormone (TSH). The objective of this study is to define FT4 and TSH values in very preterm infants (<32 weeks postmenstrual age, PMA) and correlate hypothyroxinemia and levothyroxine treatment with growth velocity at 28 days and 36 weeks PMA.

Methods

Preterm neonates <32 weeks PMA admitted to the regional neonatal intensive care unit (NICU) at the Children’s Hospital of Georgia (USA) between January 2010 and July 2022 were routinely screened for hypothyroxinemia. FT4 and TSH values were obtained on 589 eligible neonates between day of life (DOL) 4 and 14. Growth velocity (g/kg/day) from DOL 14 to DOL 28 and 36-weeks PMA were calculated for each neonate and potential explanatory variables (PMA, sex, and race) were incorporated into multivariate regression models to identify associations between HOP and growth velocity.

Results

In 589 preterm infants, PMA at birth was strongly associated inversely with FT4 (R=0.5845) and modestly with TSH (R=0.2740). Both FT4 and gestational age, but not TSH or levothyroxine treatment, were associated with growth velocity at 28 days of life and at 36 weeks PMA.

Conclusions

We provide a large data set for identifying FT4 and TSH measurements and identify hypothyroxinemia of prematurity as a potential mediator of slow postnatal growth in very preterm infants.

Authors: Lee Shiau-Yu , Hsu Keng-Hsien , Lin Hao-Tzu
Published: January 2024

This study presents a methodology for the Fuel Handling Accident (FHA) analysis during the long-term shutdown period with the fuels still residing in the reactor core for the Chinshan BWR/4 Nuclear Power Plant. This methodology can be used to calculate the radiation dose received by the control room personnel, assuming failure in safety systems, facilities or structures. The computer code RADTRAD is employed to perform the transport and release of radioactive inventories first, and then calculate the control room dose based on appropriate dose conversion factor for the FHA. The results show that even failure in safety systems, facilities or structures, the whole body dose, thyroid dose and beta-skin dose are well below the acceptance limits specified in the Standard Review Plan.

The physical properties of CdS is calculated by using the first principles pseudopotential plane wave method based on density functional theory (DFT). The calculated lattice parameters and elastic constants agree well with other theoretical values, and the crystal is determined to be structurally stable by the Born mechanical stability condition. The Debye temperature, Grüneisen parameters, heat capacity and thermal expansion coefficient of CdS under high temperature and high pressure were studied successfully by using the quasi-harmonic Debye model. The influence of pressure on thermal expansion coefficient and Debye temperature is greater than that of temperature. The heat capacity decreases with the increase of pressure. At high temperature and high pressure, the heat capacity approaches the Dulong-Petit limit.

In this work, the electro-optical and magnetic characteristics of Be1-xCrxS (x= 6.25%, 12.5% and 25%) are brought into investigation by employing full potential linearized augmented plane wave (FP-LAPW) scheme designed within density functional theory (DFT). The stability of the Be1-xCrxS alloy is justified by the negative values of formation energy. The band structures and density of states are examined by using GGA functional. Be1-xCrxS compound demonstrates the half-metallic (HM) ferromagnetic behavior for all doping concentrations; spin-up channel reveals the metallic character and other spin version displays the semiconductor (SC) behavior. The values of total magnetic moment (µB) are recorded as 4.0 8.0 and 16.0 µB for corresponding 6.25%, 12.5% and 25%, which mainly arises owing to Cr-3d state. Moreover, optical features including dielectric function ε(ꞷ), reflectivity, refraction, and absorption are explored within range of 0-10 eV. The maximum absorption of incident photons was found in ultraviolet (UV) span which implies their importance for optoelectronic applications. Results reveal that the studied alloy has potential applications in magnetic and optoelectronic gadgets.

The present work has examined the thermal features of glassy chacogenide materials Se0.75-xTe0.25Agx (x = 0, 2, 4, 6, 8, 10 at %). The thermal stability of these compositions has been assessed under non-isothermal conditions using Differential Scanning Calorimetry (DSC), which has been used to find the glass transition temperature (Tg), the initial crystallization temperature (Tin), the temperature corresponding to the top of the crystallization rate (Tp), and the melting temperature (Tm). In addition, the kinetic parameter Kr(T) was given as an additional sign of thermal stability. Among these compositions, it was discovered that Se0.71Te0.25Ag0.04 had the best glass-forming ability and glass-thermal stability. The average coordination numbers of the considered samples have been discussed in relation to these results. Additionally, we measured the sheet resistivity, ρ, whose thickness is equivalent to 1000 nm at heating rate 5 K/min, in this work to study the crystallization kinetics of thick films of Se0.75-xTe0.25Agx (x = 0, 2, 4, 6, 8, 10 at %) in the temperature range of 300 to 625 K. This range was sufficient to draw attention to two substantial areas in the resistivity versus temperature curve, and the derivation of resistivity as a function of temperature established that the films under study only had one crystallization region.

Y2O3 coatings were fabricated on using atmospheric plasma spraying (APS). The effects of different process parameters on the microstructure and properties of the coating were analyzed. The results show that the overall morphology of Y2O3 coatings are smooth at high spraying power, low spraying distance and low primary gas flow rate, which is consistent with the change trend of porosity and hardness. The minimum porosity of coating is about 1.4%. The roughness of coatings isn’t sensitive to changes in parameters. Y2O3 coatings have excellent corrosion resistance. The smaller the porosity of Y2O3 coating, the better the corrosion resistance.

The VSX/TiO2 composite layer was successfully prepared by adding Na2S and Na3VO4 into electrolytes through micro-arc oxidation (MAO) method. The structure, morphology and tribological properties were analyzed by X-ray diffraction, scanning electron microscopy and 3D true color microscopy. The results show that when the concentration of Na2S is 10-20 g/L, the thickness of VSx/TiO2 composite layer is the thickest, and the friction coefficient and volume wear are the lowest. The VSx/TiO2 composite layer in-situ prepared by MAO can improve the tribological properties of TC4 alloy at high temperature.

In the present study, Ti3C2Tx type MXene was prepared by selective etching of Al from Ti3AlC2 with mesh size of 200. The powder form of raw material was used to fabricate Ti3C2Tx by in-situ HF etching method. The MXene is further coated on non-woven paper by simply dip coating method. The detailed structural, morphology and elemental content study of as prepared Ti3C2Tx MXene have demonstrated. The MXene (Ti3AlC2) powders show compact, layered morphology as expected for bulk layered ternary carbide. The detailed elemental analysis has carried out for Titanium carbide based MXene coated and uncoated woven paper. The lower conducting property obtained for paper coating due less amount of coating in the surface of paper instead of coating on glass substrate. The electrical property characterization of MXene coated non-woven paper and glass substrate have also been studied. Hence, the conductive coating of MXene-in water formulation achieved through simple dip coating methods is promising for low cost sensor, wearable shielding device fabrication towards renewable energy and healthcare applications.

First-principles DFT calculations by utilizing FP-LAPW under GGA+PBE method are performed to investigate the structural, electronic and optical characteristics of bromide perovskites MGeBr3 (M = Rb, Cs, Fr). It is found that the cubic structure (Pm-3m) and optimized lattice constants are in good agreement with the previous data. Our GGA+PBE results reveal that MGeBr3 show nonmagnetic semiconductor behavior with direct bandgap (Eg = 0.925 eV (M = Rb), 0.898 eV (M = Cs), 0.952 eV (M = Fr)) along the L–L symmetry direction. Formation energy, octahedral ration and tolerance factor for MGeBr3 have also been calculated. The 2-D charge densities confirm that the chemical bonds (Ge2+–Br- ) and (M+–Br- ) follow the covalent and ionic bonding types. Moreover, we have calculated and discussed the optical parameters, dielectric constants, absorption, conductivity and refractivity. The calculated electronic and optical properties show the narrow band-gap, high absorption and semiconductor nature making these inorganic materials suitable for optoelectronics applications.

Graphene nanoplatelets (GNP) are just one of the attractive graphene-based nanomaterials that are rapidly emerging and have sparked the interest of many industries. These small stacks of platelet-shaped graphene sheets have a unique size and morphology that quickly disperse into other materials such as polymers, resulting in higher-value composite materials with improved thermal, conductivity, and mechanical capabilities. A detailed analysis of reinforced High-Density Polyethylene (HDPE) using different sizes (2, 15, 25 µm) and compositions (8, 10, 15 wt.%) of Graphene Nanoplatelets (GNP) has been conducted. The microstructure of the HDPE/GNP nanocomposites was extensively examined during the melt blending and injection moulding processes. Based on the results, the nanocomposites with different sizes of GNP exhibited dissimilar behaviour with different compositions. Furthermore, scanning electron microscope (SEM) results indicated a homogeneous dispersion for GNP in melt mixing. Moreover, thermogravimetric (TG) data demonstrate that increasing filler showed a slight increase in the material's thermal stability. The use of GNP improved mechanical properties, as evidenced by the increases in Young's modulus of yield strength from around 100 MPa to over 400 MPa. This study provides a practical reference for the industrial preparation of polymer-based graphene nanocomposites.

The Enteromorpha prolifera biochar and 4A zeolite-modified biochar based on different pyrolysis temperatures were prepared. The biochar of good biocompatibility with Bt was selected by studying the effects of different biochar on the survival rate and salt tolerance of Bacillus thuringiensis (Bt). The biochar microspheres loaded with Bt were prepared with sodium alginate, pectin, and chitosan. The effects of the addition of biochar on the particle size and ball formation rate of the microspheres were investigated. The structure of the microspheres was characterized by SEM and FTIR, and the SR of the microspheres under different pH conditions were evaluated. The results showed that 4A zeolite-modified biochar prepared at 500 ℃ (GH500) had good compatibility with Bt, and could improve the salt tolerance of Bt. The prepared microspheres have a uniform shape and particle size, and their swelling characteristics were pH-responsive, the microspheres containing biochar exhibited good swelling properties under alkaline conditions.

Mo1-xCoxS2 (0 ≤ x ≤ 0.1) nanoparticles were successfully synthesized by using a hydrothermal route. The crystal structure of the prepared samples was investigated by Xray diffraction (XRD), emphasizing that all the prepared samples had a hexagonal structure of MoS2, and revealed an increment in the average particle size from 5 to 8 nm with increasing the cobalt ratio. The morphology was examined using scanning electron microscopy (SEM), and the recorded images of pure and cobalt-doped MoS2 show flowerlike architecture clusters. FT-IR spectroscopy was carried out to detect functional groups and stretching and bending vibrations of chemical bonds existing in all the prepared samples, confirming the presence of Mo-O and Co-O-Co characteristic peaks. The chemical composition of the synthesized samples was determined by energy dispersive Xray (EDX) analysis. The results confirmed the presence of Mo, S, and Co, which are consistent with the proposed formation of Mo1-xCoxS2 nanosystems. Optical properties were examined by UV–Visible spectrophotometry, reflecting allowed direct transitions with an energy band gap that decreases from 1.9 eV to 1.53 eV with increasing cobalt concentration. The photocatalytic degradation efficiency of methylene blue (MB) using pure and different ratios of cobalt-doped MoS2 as catalysts was tested under visible light radiation, and it was noticed that the MB degradation increased with increasing cobalt concentration.

Silica-cenosphere aerogels were calcined at 1200ºC, as α-cristobalite phase was formed in silica aerogel at 1200°C. At temperatures less than 1200°C only amorphous silica was found in silica aerogel. Microstructural analysis showed spherical shape in different sizes with micro pores in surface of cenosphere and popcorn-like structure in silica-cenosphere aerogels. Effect of cenosphere addition in silica aerogel was studied by FT-IR. The particle size and distribution of prepared aerogels and cenosphere were analysed by particle size distribution analyser. The average particle size of silica aerogel was found to reduce by increased addition of cenosphere. The nitrogen adsorption studies of cenosphere and silicacenosphere aerogels indicated type II isotherm which represents macroporous/nonporous unrestricted monolayer – multilayer adsorption. The powder flow behaviour of the cenosphere and prepared aerogels were found to be strongly dependent on the particle size and distribution. The compressive strength and thermal conductivity of all the samples were found to be dependent on the porosity and bulk density. Among all the samples, lower density and higher porosity was observed in SC15. The silica aerogel recorded the highest strength value and was reduced by the addition of cenosphere except for SC5. The thermal conductivity was also found to be lowered for silica-cenosphere aerogels than pure silica aerogel and was found suitable for thermal insulation application that do not require strength.

Published: January 2024

Lean production is very widely used and thoroughly tested approach among various enterprises for many decades, its motive is to remove non-value-added activities (waste) from the value stream and make the system highly optimized and efficient. Industry 4.0 is combination of technology driven applications that merge the traditional physical industry to cyber word with the use of digital technology, IoT and sensors etc. In today’s highly competitive and volatile market scenarios it is very hard to fulfill the consumer demands and to produce highly customized quality product, without applications of integrated lean principles and industry 4.0 technologies. This combination known as lean 4.0, is not a replacement for either Industry 4.0 or Lean, but rather a way to improve the performance of the industrial sector. This study looks at how lean manufacturing principles can be used with Industry 4.0 to help India's hard-hit Micro, Small, and Medium-Enterprises (MSMEs). The concepts of lean 4.0 were tested in selected Micro, Small, and Medium-Sized Enterprises at the NCR region in India. Different parameters of productivity and customer satisfaction index has been compared after traditional lean and lean 4.0 implementation, there is a significant improvement has been observed as a result, another aim of this study is to put effort to persuade MSMEs to accept this fusion in order to boost productivity, quality and customer satisfaction.
A Model Study on the Effects of n-Mesons on Thermodynamics of Strongly Interacting Systems
Authors: Saha Kinkar
Published: January 2024

Properties of strongly interacting matter are quite well-described by the Polyakov loop enhanced Nambu-Jona—Lasinio (PNJL) model as it incorporates two important symmetries. However, discrepancies in low temperature domain remain unless hadronic effects are entwined. Here we have tried to observe the effect of lowest lying hadrons i.e. ?-mesons (pions) considering their medium-dependent masses for zero chemical potential. The thermodynamic quantities now show satisfactory matches with existing lattice QCD and HRG results over the finite temperature window of interest.

Analysis Of Stock Prediction Parameters and Their Impact on Effective Selection Of Stock
Authors: Dagwar Er. Mausami Sawarkar , Agrawal Sachin
Published: January 2024

Stock value prediction is a multi-disciplinary field which requires efficient knowledge about the stock’s historic values, its news feeds, twitter sentiments, impact of global stock market(s) on the stock, etc. In order to effectively analyse a stock’s trend for inter-day, intra-day or long term, analysists have to evaluate these values on a continuous basis. Along with these values analysists also have to analyse non-stock data like recent news about the company, management changes in the company, tweets related to the company, global news & global stock market trends which affect the company in any way possible. Each of these data sources have a different effect on the stock’s value change, and it is recommended for a good stock prediction system to analyse the effects of these values before real-time deployment. Neglecting even a single parameter before deployment of the stock prediction system might result into a multitude of prediction errors. For instance, if twitter feeds for a stock are not considered during prediction of a nicely performing stock, and suddenly some news about a product fail comes online, then the stock prices might plummet, and the system will not be able to track it. In order to reduce the effect of these outlier events on predicted value of the stock, this paper analyses different parameters that affect stock prediction, and suggest the impact of these parameters on stock performance. Researchers can use this information in order to improve the accuracy of their deployed systems, and make these systems future proof.

Background: Iron deficiency (ID) is a major heart failure comorbidity associated with increased mortality, worse symptoms and a poorer quality of life, irrespective of anaemia. In Nepal, limited data are available to permit an estimation of the spectrum and prevalence of ID associated with heart failure, which the present study aimed to find. Methods: A single-centre, cross-sectional, observational study was conducted at a tertiary care hospital in Kathmandu, Nepal. Patients meeting validated clinical criteria of heart failure were included and assessed for their iron status. Absolute ID was defined as serum ferritin <100 μg/l and functional ID was defined as normal ferritin (100–300 μg/l), with low transferrin saturation <20%. Data were analysed using SPSS (version 23). A logistic regression model was used to calculate the OR, with p-values <0.05 and 95% CIs. Results: A total of 400 patients were studied. Anaemia was present in 244. ID was present in 314 (78.5%) patients, out of which absolute deficiency was present in 181 (57.6%) and functional deficiency was present in 133 (42.4%) patients. ID with anaemia was present in 222 patients. Female sex (OR 1.93; 95% CI [1.18–3.18]), New York Heart Association class III/IV (OR 2.46; 95% CI [1.48–4.07]), age >65 years (OR 1.97; 95% CI [1.21–3.21]) and anaemia (OR 7.01; 95% CI [4.08–12.06]) were significantly associated with ID. ID without anaemia was present in 29% of patients. Conclusion: The present study showed a high prevalence of ID in heart failure patients, which was significantly associated with older age, female sex and higher New York Heart Association class. It also showed that a significant number of patients who were non-anaemic had ID. Therefore, iron profiling and treatment should be a part of the routine assessment of patients with heart failure.
