Disturbances in pro/antioxidant balance emerge as a crucial element in bipolar disorder (BD). Some studies suggest that treatment effects on trace element concentration in BD. This study aimed to identify (a) the changes related to oxidative stress in BD and their relationship with trace elements engaged in pro/antioxidant homeostasis; (b) BD biomarkers using machine learning algorithm classification and regression tree (C&RT) analysis.

Objective: To investigate whether Molybdenum blood level is a marker of cancer risk on BRCA1 carriers.

Methods: A prospective cohort study was conducted among 989 initially unaffected women with a BRCA1 mutation. Blood samples were collected to measure molybdenum levels, and participants were followed for an average of 7.

The aim of the project was to evaluate the association between selenium (Se) and zinc (Zn) levels in blood and serum and kidney cancer mortality. In a prospective group of 284 consecutive, unselected patients with kidney cancer, we evaluated their 10-year survival rate in relation to the levels of Se and Zn in their blood and serum. Micronutrient levels were measured using an inductively coupled plasma mass spectrometer.

Prostate cancer is the most common cancer diagnosed in men and the second leading cause of death in male cancer patients. The WHO suggests that cobalt is involved in the carcinogenesis of prostate cancer. There are, however, no studies associating cobalt levels and prostate cancer patient survival.

Pathogenic mutations in BRCA1 (BReast CAncer gene 1) confer high risks of both breast (up to 70%) and ovarian (up to 40%) cancers. Zinc (Zn) and copper (Cu) are essential for various physiological functions, including antioxidant reactions. Their balance, reflected in the Zn/Cu ratio, plays a crucial role in maintaining redox homeostasis, which is vital for cancer prevention.

Breast cancer and ovarian cancer pose a significant risk for BRCA1 carriers, with limited risk-reduction strategies. While improved screening helps in the early detection of breast cancer, preventive measures remain elusive. Emerging evidence suggests a potential link between iodine levels and modulation of cancer risk, but comprehensive studies are scarce.

Article Synopsis
  • A study measured selenium and arsenic levels in blood and serum from 336 psoriatic patients and 336 healthy controls to explore links with psoriasis severity.
  • Results showed significantly lower selenium levels in patients, particularly in those with severe cases, while arsenic levels did not differ notably between the two groups.
  • The findings suggest that low selenium levels are associated with higher psoriasis risk, indicating a need for further research on selenium supplementation as a potential treatment strategy.

BRCA1 mutations predispose women to breast and ovarian cancer. The anticancer effect of zinc is typically linked to its antioxidant abilities and protecting cells against oxidative stress. Zinc regulates key processes in cancer development, including DNA repair, gene expression, and apoptosis.

Article Synopsis
  • - BRCA1 mutations significantly raise the chances of developing breast and ovarian cancer, and while environmental factors can also play a role, the specific impact of lead exposure on BRCA1 carriers hasn’t been studied until now.
  • - A study involving 989 BRCA1 mutation carriers in Poland found that elevated blood lead levels (above 13.6 μg/L) are linked to a higher risk of ovarian cancer, with HR values indicating more than triple the risk in univariable analysis.
  • - The research suggests that BRCA1 carriers with high lead exposure may benefit from preventive measures like salpingo-oophorectomy (removal of ovaries and fallopian tubes); however, more studies are needed to confirm this

Cadmium (Cd) is a known carcinogen, but its impact on cancer risk at lower concentrations is poorly understood. Previous studies on Cd and cancer risk in men show inconsistent results, prompting further investigation. A prospective cohort study involving 2956 men was conducted.

This study continues the research in which we determined the concentration of aluminum in children receiving long-term parenteral nutrition (LPN). Since our results were interesting, we decided to assay arsenic (As) and cobalt (Co) in the collected material, which, like aluminum, constitute contamination in the mixtures used in parenteral nutrition. Excesses of these trace elements in the human body are highly toxic, and deficiencies, particularly in the case of Co, can lead to various complications.

There is emerging interest in the relationship between several serum micronutrients and the prognosis of patients with breast cancer. The relationship between serum zinc and copper levels and breast cancer prognosis is unclear. In our study, we included 583 patients with breast cancer diagnosed between 2008 and 2015 in the region of Szczecin, Poland.

The most prevalent type of cancer among males is prostate cancer. Survival is considered quite good, but it can be further improved when risk factors are optimized. One of these factors is micronutrients, including Se and Zn.

Background: Micronutrients are important components for the homeostasis of the human body. The studies available in the literature of the subject on their impact on the risk of population diseases, including malignant neoplasms, are ambiguous. In this paper, the relationship between Cu and Zn serum levels and the occurrence of endometrial cancer have been analyzed.

  • A study measured levels of selenium (Se), zinc (Zn), and copper (Cu) in the serum of 1,475 cancer patients (breast, prostate, lung, larynx) after diagnosis but before treatment at University Hospitals in Szczecin, Poland.
  • Patients were monitored for 6.0-9.8 years, and hazard ratios (HRs) were calculated to assess associations between these elements and all-cause mortality.
  • Higher levels of Se (HR = 0.66) and Zn (HR = 0.55) were linked to reduced mortality, while higher levels of Cu were associated with increased mortality (HR = 1.91), indicating a significant relationship

Background: Available studies on the effect of serum selenium levels on the risk of malignancies show some conflicting results. In this study, we investigated the correlation between serum selenium levels and ovarian cancer occurrence.

Methods: 314 women (157 diseased patients and 157 healthy ones) matched in terms of age and BMI were included in the study.

The malignant melanoma of the skin is a very aggressive tumor. The determination of prognostic biomarkers is important for the early detection of recurrence, and for the enrollment of the patients into different treatment regimens. An evaluation of a cohort of 375 Polish MM cases revealed that a low serum iron concentration (i.

Background: Numerous studies have shown a relationship between low serum selenium levels and an increased risk of developing cancer. Methods: A total of 306 women participated in the study: 153 patients diagnosed with endometrial cancer and 153 healthy women who were matched, in terms of birth year (+/−3 years), to the patients from the study group. The quantitative measurement of selenium content in the collected blood samples was performed using a mass spectrometer with excitation in inductively coupled plasma.

  • The study estimated the risk of developing thyroid cancer in patients who had previously been diagnosed with breast cancer, tracking 10,832 women for an average of 14 years.
  • Out of the participants, only 53 (0.49%) developed thyroid cancer, significantly higher than the expected rate based on Polish population statistics.
  • Women with specific mutations in the CHEK2 gene showed a higher ten-year risk of thyroid cancer (1.5%) compared to those without mutations (0.9%), with particular mutations linked to higher hazard ratios for developing the disease.

There is a need for sensitive and specific biomarkers for the early detection of colorectal cancer. In this retrospective study, we assessed whether a high blood copper level was associated with the presence of colorectal cancer. The blood copper level was measured among 187 colorectal cancer patients and 187 matched controls.

  • * Results showed that low blood arsenic levels (0.27-0.67 µg/L) were linked to a higher frequency of CRC, with odds ratios (OR) indicating a significant association (e.g., OR: 3.69).
  • * Furthermore, certain gene variants enhanced this correlation, with very high odds ratios for specific polymorphisms, suggesting a potential biomarker role, but the authors recommend further research for validation due to the new insights.
