CHI3L1 in Multiple Sclerosis-From Bench to Clinic.

Multiple sclerosis (MS) is a chronic demyelinating disease of the central nervous system (CNS) with a complex and not fully understood etiopathological background involving inflammatory and neurodegenerative processes. CHI3L1 has been implicated in pathological conditions such as inflammation, injury, and neurodegeneration, and is likely to play a role in the physiological development of the CNS. CHI3L1 is primarily produced by CNS macrophages, microglia, and activated astrocytes.

Concentrations of Bioelements (Zn, Cu, Fe, Cr, Mg, Mn) in Serum and Bone Tissue of Aging Men Undergoing Hip Arthroplasty: Implications for Erectile Dysfunction.

Erectile dysfunction (ED) stands out as one of the most prevalent sexual disorders in men, with its incidence progressively escalating with age. As delineated by the International Consultation Committee for Sexual Medicine on Definitions/Epidemiology/Risk Factors for Sexual Dysfunction, the prevalence of ED among men under 40 years is estimated to be within the range of 1-10%. The aim of this study was to determine the relationship between the concentration of bioelements (Zn, Cu, Fe, Cr, Mg, and Mn) in the serum and bone tissue and the concentration of selected hormones in men with and without erectile dysfunction.

Individual Factors Modifying Postoperative Pain Management in Elective Total Hip and Total Knee Replacement Surgery.

Total hip and knee replacements are the most common orthopedic procedures performed due to osteoarthritis. Pain is an intrinsic symptom accompanying osteoarthritis, persisting long before surgery, and continuing during the preoperative and postoperative periods. Appropriate pain management after surgery determines the comfort, duration, and cost of hospitalization, as well as the effectiveness of postoperative rehabilitation.

Level of Disability after Total Hip Replacement in Patients with Some Gene Polymorphism.

Background: The gene encodes the enzyme catechol-O-methyltransferase, which is a key modulator of dopaminergic and adrenergic neurotransmission. Hip osteoarthritis is accompanied by reduced mobility and some level of disability. In our study, we analyzed the association between some gene polymorphisms and reduced mobility in patients after total hip replacement (THR).

Adherence to therapy among liver transplant patients as related to depression, anxiety, acceptance of the disease, and social support.

Objective: This study aimed to assess the patients' adherence to therapeutic regimens after liver transplantation, taking into account the levels of depression and anxiety, acceptance of the disease, and social support.

Patients And Methods: The study group included N = 112 patients selected from 669 patients after liver transplantation. The Delphi method was used to develop a tool to assess the level of adherence to treatment regimens.

Metabolic Syndrome in Aging Men as a Factor Affecting the Relationship between Mg, Ca, and P in Serum and Bone.

The objective of this study was to evaluate the relationship between the prevalence of metabolic syndrome (MetS) and selected hormonal disorders and concentrations of magnesium (Mg), calcium (Ca), and phosphorus (P) in both blood serum and bone tissue. This study involved 152 men with and without MetS. In the blood of the patients we examined, we determined levels of: testosterone (TT), estradiol (E2), sex hormone-binding globulin (SHBG), dehydroepiandrosterone sulfate (DHEAS), insulin (I), osteocalcin (OC), and concentrations of markers of bone turnover.

Telenursing: The view of care professionals in selected EU countries. A pilot study.

Background: With the growth of digital nursing, several studies have focused on recording patients' views on remote care, or specialised nurse staffing aspects. This is the first international survey on telenursing focused exclusively on clinical nurses that analyses the dimensions of usefulness, acceptability, and appropriateness of telenursing from the staff point of view.

Methods: A previously validated structured questionnaire including demographic variables, 18 responses with a Likert-5 scale, three dichotomous questions, and one overall percentual estimation of holistic nursing care susceptible to being undertaken by telenursing, was administered (from 1 September to 30 November 2022) to 225 clinical and community nurses from three selected EU countries.

Nursing interventions reduce postoperative urinary retention in fast-track total hip arthroplasty: A pilot study.

Background: Postoperative urinary retention (POUR) is a common complication of spinal anesthesia that occurs in 10-80% of patients after total hip replacement (THR). Bladder catheterization carries risks for urinary tract infections, mechanical urethral trauma, urethral inflammation and subsequent strictures, pain, discomfort, an increased length of hospital stay, and a loss of patient dignity.

Objectives: We investigated whether simple postoperative nurse-driven intervention protocols, including the sound of running tap water, followed by caffeinated hot beverages (tea or coffee) and pouring warm saline on the perineal area, could reduce POUR and the need for bladder catheterization.

Relationships Between Indicators of Metabolic Disorders and Selected Concentrations of Bioelements and Lead in Serum and Bone Tissue in Aging Men.

Background: The aim of this study was to investigate the relationships between serum and bone concentrations of selected bioelements, ie, zinc (Zn), copper (Cu), iron (Fe), chrome (Cr), magnesium (Mg), and selenium (Se), and a heavy metal, ie, lead (Pb), and the selected indicators of metabolic disorders - Visceral Adiposity Index (VAI), Lipid Accumulation Product (LAP) and Body Mass Index (BMI).

Material And Methods: The study comprised 151 men aged 60 to 75 years who were scheduled for hip replacement surgery due to osteoarthritis. The concentrations of elements in the serum and bone tissue were measured using inductively coupled plasma optical emission spectrometry (Mg, Zn, Cu, Cr, Fe, and Pb) and the spectrofluorometric method (Se).

Body Composition Analysis in Perimenopausal Women Considering the Influence of Vitamin D, Menstruation, Sociodemographic Factors, and Stimulants Used.

(1) The perimenopausal period and menopause are physiological stages of a woman's life, and they may result in the occurrence of many health problems. The aim of this study was to assess the impact of sociodemographic factors related to the use of stimulants and the presence of menstruation and vitamin D concentration in women's health based on the analysis of their body composition parameters. (2) The study was carried out among 191 women.

Depth profiling and standardization from the back side of a sample for accurate analyses: Emphasis on quantifying low-fluence, shallow implants in diamond-like carbon.

Rationale: Back-side thinning of wafers is used to eliminate issues with transient sputtering when analyzing near-surface element distributions. Precise and accurate calibrated implants are created by including a standard reference material during the implantation. Combining these methods allows accurate analysis of low-fluence, shallow features even if matrix effects are a concern.

Lack of Association between (AAT)n Polymorphism of the Gene Encoding the Cannabinoid Receptor (CB1) and Patient's Quality of Life.

Genetic factors may predispose persons to decreased pain excitability. One of the interesting modulators affecting pain perception may be polymorphisms of the cannabinoid receptor type 1 () gene. In this study, we examined the association between three-nucleotide repeats (AAT) polymorphism located in the 3'UTR non-translational region of and the patient's quality of life after total hip arthroplasty.

No Association between Genetic Variants of the and Genes and Pain Perception among Patients Undergoing Total Hip or Knee Arthroplasty for Primary Osteoarthritis.

Each year approximately 1 million total hip replacements are performed worldwide. The most common indications to choose this procedure are rest pain and pain after activity as well as functional limitations influencing daily activities. Experimental pain is highly variable by individuals, which is partly due to genetics.

Analysis of Side Effects Following Vaccination Against COVID-19 Among Individuals With Multiple Sclerosis Treated With DMTs in Poland.

Background And Objectives: Since vaccination against COVID-19 is available for over a year and the population of immunized individuals with autoimmune disorders is higher than several months before, an evaluation of safety and registered adverse events can be made. We conducted a large study of side effects following the COVID-19 vaccine among patients with multiple (MS) sclerosis treated with disease-modifying therapies (DMTs) and analyzed factors predisposing for particular adverse events.

Methods: We gathered data of individuals with MS treated with DMTs from 19 Polish MS Centers, who reported at least one adverse event following COVID-19 vaccination.

High Levels of Thromboxane (TX) Are Associated with the Sex-Dependent Non-Dipping Phenomenon in Ischemic Stroke Patients.

Background: Inflammation and high blood pressure (nondipping profile) during the rest/sleep period have been associated with an effect on the incidence of cardiovascular disorders and a more severe course in the ischemic cerebrovascular event. There are no available data on the relationship between dipping status and the pro-inflammatory metabolites of arachidonic acid (AA); therefore, we undertook a study to investigate the influence of thromboxane on the incidence of nondipping among patients after stroke.

Methods: Sixty-two patients with ischemic stroke (including 34 women and 28 men) were tested for the involvement of thromboxane in the nondipping phenomenon.

Discovery of a first-in-class reversible DNMT1-selective inhibitor with improved tolerability and efficacy in acute myeloid leukemia.

DNA methylation, a key epigenetic driver of transcriptional silencing, is universally dysregulated in cancer. Reversal of DNA methylation by hypomethylating agents, such as the cytidine analogs decitabine or azacytidine, has demonstrated clinical benefit in hematologic malignancies. These nucleoside analogs are incorporated into replicating DNA where they inhibit DNA cytosine methyltransferases DNMT1, DNMT3A and DNMT3B through irreversible covalent interactions.

Electron Microprobe/SIMS Determinations of Al in Olivine: Applications to Solar Wind, Pallasites and Trace Element Measurements.

Electron probe microanalyzer measurements of trace elements with high accuracy are challenging. Accurate Al measurements in olivine are required to calibrate SIMS implant reference materials for measurement of Al in the solar wind. We adopt a combined EPMA/SIMS approach that is useful for producing SIMS reference materials as well as for EPMA at the ~100 μg g level.

Elemental abundances of major elements in the solar wind as measured in Genesis targets and implications on solar wind fractionation.

We present elemental abundance data of C, N, O, Na, Mg, Al, Ca, and Cr in Genesis silicon targets. For Na, Mg, Al, and Ca, data from three different SW regimes are also presented. Data were obtained by backside depth profiling using Secondary Ion Mass Spectrometry.
