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

Background: 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. Materials and methods: The retrospective cohort study included 152 men who underwent total hip arthroplasty for hip osteoarthritis at the Department of Orthopaedic Traumatology and Musculoskeletal Oncology at the Pomeranian Medical University in Szczecin. Certain exclusion criteria were applied to ensure the integrity of the study. These included individuals with diabetes, a history of cancer, alcohol abuse, liver or kidney failure, New York Heart Association (NYHA) class III or IV heart failure, and those taking medications that affect bone metabolism, such as mineral supplements, neuroleptics, chemotherapeutic agents, immunosuppressants, corticosteroids, or antidepressants. Patients with hypogonadism or infertility were excluded from the study. Results: The study showed an association between bioT concentrations and Cu concentrations in both patients with and without erectile dysfunction. A correlation between bioactive testosterone and Cr concentrations was also observed in both groups. Patients with erectile dysfunction showed a relationship between bioT concentration and Zn concentration, TT concentration and Mn concentration, FT concentration and Zn concentration, and E2 concentration and Cr concentration. An analysis of elemental concentrations in bone tissue showed an association between FT and Mg and Mn concentrations, but only in patients with erectile dysfunction. In patients without erectile dysfunction, a correlation was observed between FT and Cu concentrations. A correlation was also observed between bioT concentrations and Mg, Mn, and Zn concentrations, but only in patients with erectile dysfunction. In patients without erectile dysfunction, a correlation was observed between bioT and Cu concentrations. Conclusions: Studying 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 may be important in explaining the etiology of the problem. The study of the concentration of Zn and Cu in bone tissue and serum showed that these two elements, regardless of the place of accumulation, may be related to the concentration of androgens in men.

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. The concentration of Mg, Ca, and P was determined in the serum and bone tissue. In patients with MetS, the serum Ca concentration correlated with procollagen type I N-terminal propeptide (PINP) and parathyroid hormone (PTH). Among patients without MetS, the serum Ca concentration correlated with SHBG and OC, while Ca concentration in bone correlated with the lipid accumulation product (LAP) index and the body mass index (BMI). After analyzing the serum Mg concentration, positive correlations were observed with E2, PINP, and PTH in patients with MetS. In patients without MetS, the Mg concentration in bone positively correlated with the BMI and the LAP index. Our study findings suggest that increased Mg levels could have an impact on bone tissue metabolism. Elevated serum Mg levels may be associated with changes in sex hormone concentrations and alterations in bone turnover markers.

Iron, Zinc, Copper, Cadmium, Mercury, and Bone Tissue.

The paper presents the current understanding on the effects of five metals on bone tissue, namely iron, zinc, copper, cadmium, and mercury. Iron, zinc, and copper contribute significantly to human and animal metabolism when present in sufficient amounts, but their excess or shortage increases the risk of developing bone disorders. In contrast, cadmium and mercury serve no physiological purpose and their long-term accumulation damages the osteoarticular system. We discuss the methods of action and interactions between the discussed elements as well as the concentrations of each element in distinct bone structures.

The Effects of Calcium, Magnesium, Phosphorus, Fluoride, and Lead on Bone Tissue.

Bones are metabolically active organs. Their reconstruction is crucial for the proper functioning of the skeletal system during bone growth and remodeling, fracture healing, and maintaining calcium-phosphorus homeostasis. The bone metabolism and tissue properties are influenced by trace elements that may act either indirectly through the regulation of macromineral metabolism, or directly by affecting osteoblast and osteoclast proliferation or activity, or through becoming part of the bone mineral matrix. This study analyzes the skeletal impact of macroelements (calcium, magnesium, phosphorus), microelements (fluorine), and heavy metals (lead), and discusses the concentration of each of these elements in the various bone tissues.

Comparative Analysis of the Influence of Selected Physical Factors on the Level of Pain in the Course of Temporomandibular Joint Disorders.

Introduction: Temporomandibular joints (TMJs) play a very significant function in the activity of the locomotor system of the masticatory system. But they are often a source of pain, myopathy, myoarthropathy, and malfunction of their surrounding or internal structures. The treatment of a patient's discomfort associated with masticatory system dysfunctions strongly depends on their cause. Aim of the Study. The objective of the study was to evaluate the impact of selected physical factors: LED light therapy with electromagnetic field and cryotherapy for the level of pain, in the treatment of patients suffering from temporomandibular disorders (TMDs). Materials and Methods: The study included 60 patients of both genders with diagnosed TMD in a clinical trial. The participants were randomly divided into two groups. Each group consisted of 30 people and was subjected to separate therapies in which LED light therapy with electromagnetic field (MLT) and cryotherapy (CT) were applied. Results: Having assessed the results of the author's own research in terms of analgesic activity, determined on the VAS scale during the daily routine activity of the mandible and its individual movements, in general, each of the studied groups demonstrated a considerable decrease in the level of the patients' perception of pain (<0.001). Having compared both the therapeutic methods used, a greater reduction in the level of perceived pain was achieved with MLT (p=0.002). The type of therapy used turned out to be the only significant factor for the magnitude of this reduction. Conclusions: Conclusions based on the results of our own research indicate that the selected methods of treatment demonstrate an analgesic effect in terms of the overall discomfort in the course of TMD, and that they may be an alternative pain relief thereby reducing the patient's intake of painkillers.

The Relationship between Selected Bioelements and Depressiveness Associated with Testosterone Deficiency Syndrome in Aging Men.

Background and Objectives: Abnormal concentrations of bioelements (magnesium, manganese, chromium, copper, zinc) have been associated with physical and emotional dysfunctions, including depression. This association, however, has not been analyzed in testosterone deficiency syndrome (TDS) or patients with depressiveness, i.e., when individual symptoms do not form the picture of a full-syndrome depressive disorder. This study aimed to assess the relationship between concentrations of selected bioelements and the incidence of depressive symptoms in men aged 50 years and older with a concurrent testosterone deficiency syndrome. Material and Methods: Blood samples were taken from 314 men; the mean age of the population was 61.36 ± 6.38 years. Spectrophotometric method for biochemical analysis of magnesium (Mg), manganese (Mn), chromium (Cr), copper (Cu), and zinc (Zn) was used. The diagnosis of testosterone deficiency syndrome (TDS) was based on the total testosterone (TT), free testosterone (FT), estradiol (E2), and dehydroepiandrosterone sulfate (DHEAS) levels by ELISA. Each participant completed the Androgen Deficiency in Aging Male (ADAM) questionnaire, as well as the Beck Depression Inventory (BDI-Ia) measuring the severity of depressive symptoms. Results: Emotional disturbances manifested as depressive symptoms were diagnosed in 28.7% of all participants and testosterone deficiency syndrome in 49.3%. In the TDS group, the analysis showed a significant correlation between the level of manganese (R = 0.225, p = 0.005) and chromium (R = 0.185, p = 0.021) with the incidence of depression. Conclusions: The results of our study demonstrated a relationship between manganese and chromium concentrations with the incidence of depression in men aged 50 years and older with a concurrent testosterone deficiency syndrome. This may indicate that there is a correlation between these bioelements, as well as emotional disorders manifested as depressive symptoms in aging men with a diagnosed testosterone deficiency.

Impact of Varied Factors on Iron, Nickel, Molybdenum and Vanadium Concentrations in the Knee Joint.

The aim of this study was to determine the concentrations of iron, nickel, molybdenum, and vanadium in the knee joint. We also examined the relationships between the concentrations of these metals in the knee joint and the influence of varied factors on the concentration of Fe, Ni, Mo, and V. The study of these trace elements is important, because these elements are used alone and in combination in diet supplements, and they are components of biomaterials implanted in medicine. The study materials, consisting of the spongy bone, cartilage, meniscus, anterior cruciate ligament (ACL), and infrapatellar fat pad, were obtained from 34 women and 12 men from northwestern Poland. The concentrations of Ni, Fe, Mo, and V were determined using spectrophotometric atomic absorption in inductively coupled argon plasma (ICP-AES). We found significantly higher Mo concentrations in the ACL of women than men. There was a significant difference in the Mo concentration in the spongy bone between patients from cities with fewer than 100,000 inhabitants and patients from cities with more than 100,000 residents. Iron concentrations in the spongy bone were higher in non-smoking patients and those who did not consume alcohol. Vanadium concentrations were higher in the infrapatellar fat pads in abstainers. In patients who had not undergone arthroscopy surgery, V concentration was lower in cartilage. The concentrations of V in the cartilage and infrapatellar fat pad were higher in osteoporotic patients than in non-osteoporotic patients. There were significant differences in Fe concentrations in the meniscus, with the lowest in osteoporotic patients. We noted lower Mo concentrations in the spongy bone of patients with rheumatoid arthritis. Furthermore, we noted some new interactions among metals in the studied structures of the knee joint. The results reported in this study show the influence of gender, place of residence, smoking, consumption of alcohol, arthroscopy surgery, osteoporosis, and rheumatoid arthritis on the Fe, Ni, Mo, and V concentrations in the studied structures of the knee joint.

Calcium, magnesium, zinc and lead concentrations in the structures forming knee joint in patients with osteoarthritis‬.

The aim of the study was to investigate the relationships between the concentrations of calcium (Ca), magnesium (Mg), zinc (Zn), and lead (Pb) in cartilage, anterior cruciate ligament, and meniscus samples obtained following knee joint surgery in patients with osteoarthritis in northwestern Poland.‬ Furthermore, we examined the relationships between the concentrations of these metals in the studied parts of the knee joint and the influences of gender, age, BMI and hypertension. We found significantly higher concentrations of Ca, Mg, and Zn in the cartilage of men than in women and a significantly higher Pb concentration in the meniscus of the men. We also found a higher concentration of Pb in the cartilage of patients over 65 years of age.‬ There were no differences in the concentrations of the studied metals between patients with and without hypertension.‬ There was no relationship between Ca, Mg, Zn, and Pb levels in analyzed materials and BMI. Furthermore, we noted some new interactions between metals in the studied structures of the knee joint. The results reported in the study shows the influence of age, gender and BMI on the Ca, Mg, Zn and Pb in the studied structures of the knee joint.

The Relationship between Diabetes Mellitus and Respiratory Function in Patients Eligible for Coronary Artery Bypass Grafting.

Introduction: Spirometry performed prior to surgery provides information on the types of lung disorders in patients. The purpose of this study was to look for a relationship between the prevalence of diabetes and spirometry parameters. Material and Methods: The study was conducted in patients with coronary artery disease who were eligible for an isolated coronary artery bypass graft in 2013. The study group included 367 patients (287 men and 80 women) aged 68.7 ± 8.4 years. They were divided into those with diagnosed diabetes (group I, n = 138, 37.6%) and without diabetes (group II, n = 229, 62.4%). Spirometry tests were performed on the day of admission to the hospital. Results: Patients with diabetes (group I) had a significantly higher body mass index than those without diabetes (group II). Spirometry tests also showed that patients with diabetes had statistically significantly lower forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1.0). Both FVC and FEV1.0 were also statistically significantly lower for overweight and obese individuals in group I than those in group II. Conclusion: Patients with diabetes eligible for coronary artery bypass grafting with concurrent overweight or obesity are more likely to have lower spirometry parameters than those without diabetes.

Concentrations of mercury (Hg) and selenium (Se) in afterbirth and their relations with various factors.

The aim of the study was to evaluate Hg and Se concentrations and Se:Hg molar ratios in the placenta, umbilical cord and fetal membranes, and to examine the relationship between the concentrations of the elements and selected factors. The study material consisted of the placenta, umbilical cord and fetal membranes obtained from 91 healthy women from northwestern and central Poland. In our study mean Hg and Se concentrations in afterbirth were ~ 0.01 mg/kg dry weight (dw) and ≤ 0.5 mg/kg dw, respectively. Correlation analysis showed negative relationships between placenta weight and Se concentration in the placenta and umbilical cord, as well as between placenta length and Se levels in the umbilical cord. We found negative correlations between THg concentration in the placenta and birth weight and between Se concentration in the placenta and umbilical cord and the morphological parameters of the placenta. Furthermore, we noted new types of interactions in specific parts of the afterbirth. In our study, Se:THg molar ratios ranged from 5 to 626; these values indicate protection against Hg toxicity.

Effects of biological factors and health condition on mercury and selenium concentrations in the cartilage, meniscus and anterior cruciate ligament.

Due the long-term nature of joint tissue remodeling processes, knee structures including meniscus and anterior cruciate ligament (ACL) can be a model for studying the bioaccumulation of mercury (Hg) and selenium (Se). The accumulation and retention of Hg in human tissues can have a negative effect on the proper functioning of homeostasis-affecting organisms. A factor of chronic poisoning with Hg forms is probably the Se:Hg ratio in tissues. Se:Hg molar ratios below one may increase Hg toxicity potentials, while molar ratios that approach or exceed one effectively may protect against Hg toxicity. Therefore, the aim of the study was to determine total mercury (THg), Se, and Se:THg molar ratios in the cartilage, meniscus and ACL of patients with osteoarthritis (OA) from northwestern Poland. In all studied samples (n=95), we observed higher Se than THg concentration. Taking into consideration the biological factors, we found significantly higher THg levels in the cartilage of women, patients under 65 years of age, patients without hypertension and in the ACL of patients with spinal degenerative disease. We found higher Se levels in the meniscus in women than in men. In all studied parts of the knee joint, we found the Se:THg molar ratio higher than one, which suggests that the joint forming structures are not much exposed to THg. Moreover the results reported here may provide a basis for establishing reference values for the meniscus and ACL in patients with OA who had undergone knee replacement surgery.

Influence of Environmental Factors and Relationships between Vanadium, Chromium, and Calcium in Human Bone.

The aim of this study was to investigate the impact of environmental factors on the concentrations of vanadium (V), chromium (Cr), and calcium (Ca) and to examine the synergistic or antagonistic relationships between these metals, in cartilage (C), cortical bone (CB), and spongy bone (SB) samples obtained following hip joint surgery on patients with osteoarthritis in NW Poland. We found significantly higher concentrations of V and Cr in spongy bone in patients who consumed game meat and also those with prosthetic implants. Chromium levels were significantly lower in patients with kidney diseases. The greatest positive correlations were found between spongy bone V and (i) the amount of consumed beer and (ii) seafood diet. Correlation analysis also showed a significant correlation between Cr levels and seafood diet. To a certain extent these results indicate that the concentrations of V, Cr, and Ca in the human hip joint tissues are connected with occupational exposure, kidney diseases, diet containing game meat, sea food, beer, and the presence of implants. Furthermore, we noted new types of interactions in specific parts of the femoral head. Vanadium may contribute to the lower bone Ca levels, especially in the external parts (cartilage and cortical bone).

[The effect of systemic cryotherapy and kinesiotherapy on blood pressure].

Introduction: Cryotherapy is a short time usage of temperatures below −100°C to make a physiological reaction to cold. The ô€irst cryotherapy in the world took place in 1978 thanks to Toshiro Yamauchi and his team who performed cryotherapy treatment on patients with Ankylosing spondylitis. The aim of the study was to determine the inô€luence of the systemic cryotherapy on the reduction of blood pressure in patients with hypertension and without it. Materials and methods: For this study it was examined 45 patients, including 36 women (80%) and 9 men (20%). All patients were undergoing 10 systemic cryotherapy treatments. 45% of them were also diagnosed with hypertension. Time of 1ô€†—ô€†˜ treatment was 1 minute, 5ô€†˜ô€†Œ ­ about 2 minutes, 10ô€†˜ô€†Œ ­ about 3 minutes. After cryotherapy each patient was directed to the kinesiotherapy treatment. Measurement of blood pressure (systolic and diastolic) patients was performed 3 times: 1ô€†—ô€†˜ day, 5ô€†˜ô€†Œ and the 10ô€†˜ô€†Œ day: before entering the chamber, immediately after the exit from the chamber and after 15 minutes of exercise (within physiotherapy). Results and conclusions: In patients with hypertension demonstrated the positive effect of cryotherapy and physiotherapy on blood pressure systolic and diastolic. In the group of patients with hypertension had signiô€icantly higher systolic blood pressure (p < 0.05) and diastolic (p < 0.001) before treatment, compared with patients without hypertension. Cryotherapy and physiotherapy has a positive effect on blood pressure.

[The influence of kinesiotaping on lumbar spine pain]. / Wplyw kinesiotapingu na dolegliwosci bólowe odcinka ledzwiowo-krzyzowego kregoslupa.

INTRODUCTION: Pain in the lumbosacral spine is currently one of the most common pain complaints among the elderly. About 72% of the Polish population younger than 40 years have at least once been treated by a doctor for back pain. Degenerative changes of intervertebral joints, overloads, intervertebral disc diseases, and dysfunction of spinal ligaments are very often responsible for the formation of back pain, which is basically a problem of the elderly, MATERIAL AND METHODS: The study was conducted among 60 residents of a Nursing Home in Szczecin with chronic lumbar pain. The age range was 56-85 years. Subjects were randomly divided into two groups of 30 (study group, where KinesioTaping was used, and a control group without KinesioTaping application). To assess the degree of pain experienced by the patient a visual analogue scale (VAS) in the horizontal format from 0-10 was used, on which subjects scored the severity of pain. Flexion, extension, tilt and rotation were measured with a tape to assess spinal and trunk mobility. RESULTS: In all patients, who had a KinesioTaping patch applied on the lumbosacral spine pain measured by VAS reduced (p ≤ 0.001). Considering respondents' sex, the spine mobility in the tilting position improved in men in the study group in terms of tilting to both sides. In all patients, the application of a KinesioTaping patch significantly improved the rotation to the right side (p ≤ 0.05), scores in the "finger-floor" flexion test (p ≤ 0.01), and the extension range (p ≤ 0.01). CONCLUSION: KinesioTaping is a beneficial method reducing pain and improving the mobility in the lumbosacral spine. The improvement was independent of the sex of the respondents.

[Dynamics of changes body composition of polish national swimming team during the one month of training camp prior the junior World Championship in Dubai in 2013]. / Dynamika zmian skladu ciala zawodników kadry polskich plywaków w okresie miesiecznego zgrupowania poprzedzajacego Mistrzostwa swiata juniorów w Dubaju w 2013 roku.

INTRODUCTION: World Championship in swimming are the most prestigious competition, where many countries around the world takes part in it. To prepare for the highest level for this type of event, swimmers need to train in adequate training base. Currently, the best center in Poland is at the Floating Arena swimming pool in Szczecin. The aim of this study was to analyze the impact training during start preparation period, on body mass composites. MATERIAL AND METHODS: For this study it was examined 14 swimmers, members of the Polish Junior National Team, who were during a training camp in Szczecin, for one month before main competition. Research consisted of 9 measurements of body composites, made by analyzer TANITA BC-420 MA. Method used was bioelectrical impedance analysis (BIA). Components taken under measurements are: body mass (BM), mean body fat (MBF), fat free mass (FFM), muscle mass (MM), total body water (TBW), and body mass index (BMI). RESULTS: All results of the last day of measurements, showed decreasing tendency comparing to the first day of measurements. The statistically important changes were reported in BM, TBW and BMI components. In this 4 weeks start preparation period, all the results slightly decreased. This tendency is highly recommended in professional sports. CONCLUSIONS: Research has shown that properly conducted training in the 4-week preparation starter, despite a decline in training loads characteristic of this period, along with a balanced diet, allows to maintain a stable body weight and the distribution of its components directly from participating in the competition, which is of great importance for athletic performance swimmers.

[Effect of low -level laser therapy and exercise in reducing the symptoms of disease in patients with osteoarthritis of the knee].

Introduction: Osteoarthritis is the most common disease of the joints contributing to the failure of movement. The disease mostly affects the older part of the population, and is associated with suffering and reduced quality of life. Knee osteoarthritis contributes to joint dysfunction of varying severity. These are common causes of chronic ailments limiting physical activity, which may even complicate the performance of activities of daily living. Low-level laser therapy is thought to have an analgesic effect, as well as a biomodulatory effect on the microcirculation. The aim of this study was to evaluate the effectiveness of low- -level laser therapy on pain relief and functional improvement in patients with osteoarthritis of the knee. The effects of laser therapy alone and in combination with exercise were compared. Materials and methods: 40 patients of mean age 65 years with knee osteoarthritis of both sexes were divided into two groups. Laser alone was used in group I (n = 20) and laser combined with kinesistherapy was used in group II (n = 20). All patients received the same dose of laser radiation, which was 3.0 J/cm², 10 Hz, 400 mW. In both groups a series of 10 treatments was performed daily. VAS, ranges of motion in the knee joint, and the strength of the quadriceps and biceps femoris muscles were used as the criteria of pain assessment in both groups. All measurements were taken before and after treatment. Results: Significant pain reduction: I (p = 0.00009, R = 0.68); II (p = 0.00002, R = 0.86), increased range of flexion in the knee: I (p = 0.000001, R = 0.90); II (p = 0.00002, R = 0.85), increased range of extension in the knee: I (p = 0.042, R = 0.87); II (p = 0.0004, R = 0.9) and increased strength of the quadriceps femoris muscle: I (p = 0.03, R = 0.77); II (p = 0.0002, R = 0.9) and the biceps femoris muscle: I (p = 0.04, R = 0.80); II (p = 0.0007, R = 0.91) were found in both groups after treatment. With the exception of flexion of the knee (p = 0.027; r = 0.17), there were no statistically significant differences in other analysed parameters between the use of laser alone and laser therapy combined with exercise. Conclusion: The use of laser in knee osteoarthritis reduces pain and improves the functional status of the patient. Laser therapy combined with kinesistherapy produces better therapeutic effects, and effectively improves the functional status of knee osteoarthritis. Exercise therapy applied in a series of 10 treatments is too short to significantly improve the functional status of the patient.

[Is training yoga regulary can have an effective impact on dealing with stress?].

Introduction: The word yoga (Goya) is derived from the Sanskrit yii and means: bind, connect, attach and focus attention on something. It also means connection, and the union. The system of yoga has collected and systematized Patanjali in his "Yoga Sittrach" work. Yoga has the task of shaping proper physical culture and spirit (mind), regardless of religious beliefs, national origin, membership in a social group. The aim of the study was to evaluate the relationship between yoga and regular coaching strategy for coping with stress, blood pressure and abdominal obesity. Material and methods: The study involved 100 people divided into 2 groups. The first group comprised students regularly practicing yoga. The second group were randomly selected subjects not regularly engaged in sport. The age of the subjects ranged 18­60 years and over. Research material was gathered using a questionnaire designed by the authors, and the mini -COPE test. In addition, blood pressure and waist circumference were measured to assess the prevalence of abdominal obesity. Results: Among people who practice yoga the average waist circumference was 82.8 ±8 in women and 90.3 ±11 in men (p < 0.034). A healthy waistline was found in 43 (86%)subjects in the yoga group, and 34 (68%) subjects in the control group. Body mass index (BMI) also falls in favour of yoga, and in this group 15 (30%) more subjects had normal BMI. Abdominal obesity and BMI indicating obesity was found in 10 (20%) subjects from the yoga group and 15 (30%) from the control group. The study revealed no significant differences in mean blood pressure between the analysed groups. Conclusions: Based on the analysis of the questionnaire mini-COPE people regularly Training Yoga choose more effective strategies for coping with stress. Regular practice of yoga is a factor in reducing abdominal obesity. Men who trains yoga have blood pressure lower than those who doesn't practice any sport.
