The Impact of Whey Protein Supplementation on Sarcopenia Progression among the Elderly: A Systematic Review and Meta-Analysis.

We conducted a systematic literature review and meta-analysis to investigate the role of whey protein supplementation in the functioning of the elderly with sarcopenia. The aim was to investigate the available scientific evidence and determine the best recommendations with respect to whey protein supplementation in sarcopenic patients. Methods: Databases, including CINAHL, Embase PubMed, and Web of Science, were searched from database inception until 31 December 2022 for randomised controlled trials (RCTs) comparing the efficacy of whey protein supplementation in the elderly with sarcopenia. Data on study design, risk of bias, patient, illness, and treatment characteristics from each study were independently extracted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The tool "assessing risk of bias" from the Cochrane Handbook was used to evaluate the quality of the included papers. Results: The search identified 629 records; 590 articles were excluded as duplicates or after evaluation at the title or abstract level. Out of 39 full-text articles that were reviewed, 29 were excluded for not fulfilling the inclusion criteria. There is some evidence that whey protein supplementation combined with age-appropriate physical exercise might improve muscle mass and lower limb function in the elderly with sarcopenia. The present meta-analysis demonstrated overall that whey supplementation does not improve any of the tested sarcopenia-linked parameters. However, we found that study duration (weeks) and age significantly affect the handgrip strength rate and the chair and stand test rate, respectively, so consideration should be given to oral supplementation combined with the age of participants and an appropriate physical activity as a form of sarcopenia prevention in the high-risk group.

Existential and Spiritual Attitudes of Polish Medical and Nursing Staff towards Death.

Issues related to death are difficult areas of human existence and are most often considered in terms of ethical or non-ethical behaviour. The aim of the research was to examine the attitudes of Polish medical and nursing personnel towards death. The research was conducted among medical (110 people) and nursing staff (110 people) working in Polish hospitals and representing 16 regions. The Questionnaire About Attitudes to Death (DAP-R-PL) was used. The attitude of medical staff, taking into account the holistic approach to the patient in his existential-spiritual dimension, is an extremely important element of professional care. The study outlines the attitudes of medical and nursing staff towards death. Medical personnel under examination demonstrate a mature attitude towards death. In light of this research, health care workers show great commitment to helping dying people with existential and spiritual needs.

Nutritional Treatment of Patients with Colorectal Cancer.

Colorectal cancer is one of the most common cancers in Europe and the world. Cancer treatments have side effects and cause significant deterioration of the patient's nutritional status. Patient malnutrition may worsen the health condition and prevent the deliberate effects of the therapy. The aim of this review was to describe the available data about clinical nutrition in colorectal cancer patients. A large proportion of colorectal cancer patients suffer from malnutrition, which negatively affects the survival prognosis, quality of life, and oncological therapy. Therefore, monitoring nutritional status during the treatment is essential and can be used to arrange proper nutritional therapy to enhance patient responses, prevent side effects, and shorten recovery time. The principles of nutrition during anticancer therapy should mainly consider light and low-fat foods, the exclusion of lactose and gluten-containing foods in certain cases, or the introduction of special dietary products such as oral nutrition supplements and it should be tailored to patients' individual needs.

Telemedicine services in the work of a doctor, dentist, nurse and midwife - analysis of legal regulations in Poland and the possibility of their implementation on the example of selected European countries.

INTRODUCTION AND OBJECTIVE: The aim of the study is to discuss the legal framework for telemedicine services in Poland, and to present telemedicine solutions used in selected European countries. MATERIAL AND METHODS: The analysis of legal cts was chosen as a research method in order to determine legal possibilities for medical professionals to use telemedicine services. A literature review was undertaken to demonstrate the possibilities of telemedicine as used in the United Kingdom, Germany, Norway, The Netherlands and Sweden. RESULTS: The Act on the professions of a doctor and a dentist states that the doctor and the dentist can perform their profession via ICT systems or communication systems. The doctor is obliged to practice in accordance with current medical knowledge and available methods. 'Available methods' include considering information and communication measures that may allow prevention, recognition or treatment. The Act on the profession of a nurse and a midwife states that the nurse and midwife perform the professions using current medical knowledge and the mediation of ICT systems or communication systems. Thus, the legislator has clearly authorized persons performing these professions to provide services in the field of telemedicine. However, despite the existence of a legal basis for using telemedicine, its development in Poland is not as high as in the United Kingdom, Germany, Norway, The Netherlands or Sweden. CONCLUSIONS: The legislator gradually introduces legal solutions necessary for the development of telemedicine services, although the pace of these changes, as well as building the technical infrastructure that is the basis for the proper provision of telemedicine services, are too slow.

An analysis of the functioning of mental healthcare in northwestern Poland.

Introduction: Modern psychiatry faces numerous challenges related with the change of the epidemiology of mental disorders and the development of knowledge in this area of science. An answer to this situation is to be the introduction of community psychiatry. The implementation of this model in Poland was the aim of the National Mental Health Protection Programme. The aim of the study was to analyse the functioning of mental healthcare using the example of the West Pomeranian Province in Poland. Materials and methods: The analysis relied on a qualitative method. Three group interviews in an interdisciplinary advisory panel were conducted. People representing various areas acting for people with mental disorders participated in each meeting. Based on the conclusions that were drawn, PEST and SWOT analyses of functioning of mental healthcare were performed. Results: Within the analysis of the macro-environment of mental healthcare, the influence of the following factors was evaluated through PEST analysis: political and legal, economic, socio-cultural, and technological. All of these factors were assessed as negative for the functioning of mental healthcare. Then, a SWOT analysis was performed to indicate the strengths, weaknesses, opportunities, and threats in the functioning of mental healthcare. Conclusions: 1. Mental healthcare is more influenced by external factors than by internal factors. 2. Macro-environmental factors influence the functioning of mental healthcare in a significantly negative manner. 3. The basic problem in the functioning of mental healthcare is insufficient funding. 4. In order to improve the functioning of mental healthcare, it is necessary to change the funding methods, regulations, the way society perceives mental disorders, and the system of monitoring mental healthcare services.

Concentrations of heavy metals (Mn, Co, Ni, Cr, Ag, Pb) in coffee.

AIM: Technologies involved in roasting coffee beans, as well as the methods used to prepare infusions, vary according to culture, and contribute to differences in the concentration of elements in the drink. MATERIALS AND METHODS: Concentrations of six elements: manganese (Mn), cobalt (Co), nickel (Ni), chrome (Cr), silver (Ag) and lead (Pb) were investigated in coffee infusions from eleven samples of coffee, roasted and purchased in four countries: Bosnia and Herzegovina, Brazil, Lebanon and Poland. Metal concentrations were determined using an induction coupled plasma technique in combination with mass spectrometry (ICP-MS, Perkin Elmer) which measures total metal (ionic and non-ionic) content. RESULTS: Metal intake estimated for individual countries (in the respective order; mean consumption per person per year) was as follows: Mn: 26.8-33.1, 28.3-29.5, 29.7, 12.6-18.9 mg; Co: 0.33-0.48, 0.42-0.35, 0.32, 0.12-0.17 mg; Ni: 3.83-5.68, 4.85-5.51, 4.04, 2.06-2.24 mg; Cr: 0.17-0.41, 0.21-0.47, 0.17, 0.09-0.28 mg; Ag: 0.16-1.13, 0.26-0.70, 0.61, 0.33-1.54 mg, Pb: 4.76-7.56, 3.59-5.13, 3.33, 1.48-2.43 mg. CONCLUSIONS: This finding gives new data for Mn, Co, Ni, Cr, and Ag intake from coffee , and suggests that the amounts are negligible. However, the data for Pb consumption in heavy drinkers, for example in Bosnia and Herzegovina, indicate that Pb intake from coffee may contribute to the disease burden. The high lead level in some coffees suggests the need for a more precise control of coffee contamination.

The influence of magnesium supplementation on concentrations of chosen bioelements and toxic metals in adult human hair. Magnesium and chosen bioelements in hair.

The basic functions of bioelements in biological systems is widely known. Depletion of bioelements and excess of toxic elements lead to impairment of metabolism in the living organism. The existence of magnesium deficiencies in the adult and pediatric populations may cause increased accumulation of toxic metals including lead and cadmium. Prevention of adverse effects of toxic metals may include supplementation with some bioelements and vitamins. The aim of this study was to evaluate the influence of magnesium supplementation on concentrations of chosen bioelements and toxic metals in hair in the adult human population. The research was performed on 124 individuals (53 males and 71 females aged 19-72 years), inhabitants of the city of Szczecin. The concentrations of magnesium, zinc, copper, lead and cadmium were studied in hair. Measurements were performed using the inversion volt-amperometry method with application of an EDD-Tribo PC ETP volt-amperometer. Finally, the supplementation study enrolled 65 individuals with an increased concentration of lead. The studied individuals were divided into two groups: one treated group that enrolled 50 patients who were supplemented with magnesium and the control group that enrolled 15 persons receiving placebo. Finally, supplementation was completed by 32 individuals from the treated group and 10 individuals from the control group. Supplementation was performed using Slow-Mag-B6 preparation at the total daily dose of five tablets divided into 2-3 doses. One tablet contains 535 mg of magnesium chloride i.e. 64 mg of magnesium ions (5.26 mEgMg2) and 5 mg of vitamin B6. Supplementation was performed for a period of 3 months. The remaining individuals did not complete the supplementation due to various reasons; however, none of them resulted from the poor tolerance of the preparation or its adverse events. The results achieved underwent statistical analysis. The results of the study revealed a positive influence of supplementation on concentrations of magnesium and copper in the human body. Supplementation with magnesium caused a statistically significant decrease in concentrations of lead and cadmium. The above mentioned results indicate a positive influence of magnesium supplementation on the decrease of lead and cadmium hair content in the individuals studied.
