Impactful Cardiac CT and MRI Articles from 2023.

Cardiac imaging is important in diagnosing, treating, and predicting prognosis in patients with cardiovascular disease. Imaging protocols and analysis are consistently evolving, and the implementation of artificial intelligence-based applications is of increasing interest. This review presents recent advancements in noninvasive cardiac imaging, specifically focusing on cardiac CT and MRI, from notable publications across multidisciplinary journals in 2023 of interest to both radiologists and referring clinicians in the field.

Novel Magnetic Resonance Imaging Tools for Hypertrophic Cardiomyopathy Risk Stratification.

Hypertrophic cardiomyopathy (HCM) is a common genetic disorder with a well described risk of sudden cardiac death; however, risk stratification has remained a challenge. Recently, novel parameters in cardiac magnetic resonance imaging (CMR) have shown promise in helping to improve upon current risk stratification paradigms. In this manuscript, we have reviewed novel CMR risk markers and their utility in HCM.

Experimental evaluation of the primary fixation stability of uncemented ceramic hip resurfacing implants.

Hip resurfacing arthroplasty is associated with increased frictional moments compared to standard heads owing to their large diameter. High frictional moments may harbor the risk of the implant loosening if the frictional moments exceed the fixation stability of the hip resurfacing arthroplasty. Therefore, the aim of this experimental study was to evaluate the fixation stability of ceramic hip resurfacing implants through a turn-off test.

Retrograde Revascularization of Tibial Arteries in Patients with Critical Limb Ischemia: Plantar-Arch Versus Transpedal Approach.

Purpose: To compare retrograde plantar-arch and transpedal-access approach for revascularization of below-the-knee (BTK) arteries in patients with critical limb ischemia (CLI) after a failed antegrade approach.

Materials And Methods: Retrospectively we identified 811 patients who underwent BTK revascularization between 1/2014 and 1/2020. In 115/811 patients (14.

Practical Cross-Layer Radio Frequency-Based Authentication Scheme for Internet of Things.

The Internet of Things world is in need of practical solutions for its security. Existing security mechanisms for IoT are mostly not implemented due to complexity, budget, and energy-saving issues. This is especially true for IoT devices that are battery powered, and they should be cost effective to be deployed extensively in the field.

[Cryptogenic organizing pneumonia versus secondary organizing pneumonia].

Organizing pneumonia (OP) describes a histological pattern of acute or subacute lung damage. Clinically, patients present with cough, fever, and dyspnea. A distinction is made between idiopathic or cryptogenic organizing pneumonia (COP) and secondary organizing pneumonia (OP).

[Computed tomography or cardiovascular magnetic resonance imaging for diagnosis of chronic coronary syndrome?].

Background: Noninvasive imaging modalities are of central importance in the diagnosis of chronic coronary syndrome (CCS) in the current guidelines of the European Society of Cardiology (ESC), while the role of primary invasive coronary angiography in this context is increasingly being questioned. This review provides a summary of the most important diagnostic strategies from the radiology perspective.

Methodological Issue: The diagnostic algorithm is guided by the pretest probability (PTP) for the presence of CCS, which can be estimated based on age, sex, and symptoms.

Towards a Comprehensive Understanding of UA-ADRCs (Uncultured, Autologous, Fresh, Unmodified, Adipose Derived Regenerative Cells, Isolated at Point of Care) in Regenerative Medicine.

It has become practically impossible to survey the literature on cells derived from adipose tissue for regenerative medicine. The aim of this paper is to provide a comprehensive and translational understanding of the potential of UA-ADRCs (uncultured, unmodified, fresh, autologous adipose derived regenerative cells isolated at the point of care) and its application in regenerative medicine. We provide profound basic and clinical evidence demonstrating that tissue regeneration with UA-ADRCs is safe and effective.

Unmodified autologous stem cells at point of care for chronic myocardial infarction.

Background: Numerous studies investigated cell-based therapies for myocardial infarction (MI). The conflicting results of these studies have established the need for developing innovative approaches for applying cell-based therapy for MI. Experimental studies on animal models demonstrated the potential of fresh, uncultured, unmodified, autologous adipose-derived regenerative cells (UA-ADRCs) for treating acute MI.

How does the content of nutrients in soil affect the health status of trees in city parks?

Trees have multi-aspect influence on the microclimate in urbanised areas. Therefore, it is important to investigate the biotic and abiotic factors affecting their health. The aim of the conducted study was to assess the chemical composition of soils and the nutritional status of lime and horse chestnut trees in selected sites and the influence of these factors on the condition and health of these tree species in urbanised areas.

High-dose therapy and autologous stem cell transplantation in marginal zone lymphomas: a retrospective study by the EBMT Lymphoma Working Party and FIL-GITMO.

The role of autologous stem cell transplantation (ASCT) in patients with marginal zone lymphoma (MZL) is debatable. This study investigated the outcome and prognostic factors affecting the outcome of patients undergoing ASCT for MZL. Eligible patients had non-transformed nodal, extra-nodal (MALT) or splenic MZL (SMZL), aged ≥18 years, who underwent a first ASCT between1994 and 2013 and were reported to the European Society for Blood and Marrow Transplantation, Fondazione Italiana Linfomi or Gruppo Italiano Trapianto Di Midollo Osseo registries.

Radioimmunotherapy-augmented BEAM chemotherapy vs BEAM alone as the high-dose regimen for autologous stem cell transplantation (ASCT) in relapsed follicular lymphoma (FL): a retrospective study of the EBMT Lymphoma Working Party.

Relapse remains the most common cause of treatment failure in patients receiving autologous stem cell transplantation (ASCT) for follicular lymphoma (FL). The aim of this study was to evaluate the effect of adding radioimmunotherapy or rituximab (R) to BEAM (carmustine, etoposide, ara-c, melphalan) high-dose therapy for ASCT in patients with relapsed FL. Using the European Society for Blood and Marrow Transplantation registry, we conducted a cohort comparison of BEAM (n=1973), Zevalin-BEAM (Z-BEAM) (n=207) and R-BEAM (n=179) and also a matched-cohort analysis of BEAM vs Z-BEAM including 282 and 154 patients, respectively.

Thalidomide in newly diagnosed multiple myeloma: influence of thalidomide treatment on peripheral blood stem cell collection yield.

In a phase III randomized, multicenter study, the German-speaking Myeloma-Multicenter Group (GMMG) and the Dutch-Belgian Hemato-Oncology Cooperative Group (HOVON) group investigated the influence of thalidomide (Thal) on the outcome of peripheral blood stem cell (PBSC) collection in multiple myeloma (MM) before peripheral autologous blood stem cell transplantation (ABSCT). We analyzed the data of 398 myeloma patients after induction with Thal, doxorubicin and dexamethasone (TAD) in comparison with vincristine, doxorubicin and dexamethasone (VAD) followed by mobilization with cyclophosphamide, doxorubicin, dexamethasone (CAD) and PBSC collection. Within both the study groups, patients treated with TAD showed to collect significantly fewer CD34(+) cells compared with VAD (GMMG, TAD: median 9.

[Iodine supply at various periods in life and ultrasonographic thyroid volume in school children in a region of Switzerland].

In Switzerland the previous severe iodine deficiency has been corrected by iodization of salt. Changing food habits make it mandatory to periodically monitor iodine intake. In 1994 we therefore measured thyroid volume by sonography in 217 schoolchildren, and iodine, creatinine and sodium in casual urine samples of 214 schoolchildren, 40 pregnant women and 30 breast-fed newborns.

[Perinatal risk in significant macrosomia. A study based on the databank of the Professional Society of Swiss Gynecologic Clinics 1983-1992].

A comparison of a group of births with severe macrosomia with a group of normal birth weight was made based on the data from the "Arbeitsgemeinschaft schweizerischer Frauenkliniken" (ASF), a work group of Swiss departments of obstetrics and gynaecology. During the period from 1983 to 1992 there were 2911 births of infants weighing more than 4500 g and 222,336 births of infants weighing between 3000 and 4000 g. Overall, the births of the macrosomic infants were more difficult, the rates of secondary Caesarean sections higher and the fetal outcomes poorer.

[Acute intermittent porphyria in pregnancy: glucose or hematin therapy?].

The symptoms and management of acute intermittent porphyria (AIP) during pregnancy and delivery are presented on the basis of three case reports. Two patients became asymptomatic after infusion of a concentrated glucose solution (600 ml 50% glucose = 300 g glucose per day), while the third patient needed treatment with hematin (1 mg/kg body weight, 6 infusions at intervals of 12 hours) because of deterioration of psychic state in spite of glucose infusion. Whenever an attack of AIP occurs, concentrated glucose solution should be administrated as a first measure accompanied by an analgesic and possibly a neuroleptic agent after elimination of precipitating factors.

[Routine measurement of the biggest amniotic fluid pocket in the 3d trimester: prognostic significance?].

The largest pocket of amniotic fluid was measured routinely during the last trimester of pregnancy in 577 patients representing risk and nonrisk cases. The measurements were performed at two clinics between 26 and 42 weeks of gestational age. A statistically significant relationship between a value of less than 30 mm and the following perinatal parameters was found: 5-min Apgar score less than 7, umbilical cord blood pH values less than 7.

[Chorionic villi (placental) biopsy in the 2d and 3d trimester: new perspectives in prenatal diagnosis].

A report of our first experience in second and third trimester chorionic villus (placental) biopsy is given. In all 16 cases a cytogenetic result could be received within 2 to 5 days. There were 6 normal female and 9 normal male karyotypes.

[The postpartum course of the HCG titer of maternal blood and its clinical relevance].

In 62 postpartum patients serial beta-HCG-measurements were performed. These tests show that beta-HCG should disappear entirely during the third week postpartum. Significant titers beyond this time are seen when placental tissue remains in utero.

[Multifocal atrial tachycardia in the newborn infant--obstetrical implications].

The present discussion deals with the rare multifocal atrial tachycardia in the neonate, initiated by a recent case in our clinic. The difficulties in prenatally diagnosing the disease by cardiotocography are as well discussed as the obstetric management.
