Fungi such as Aspergillus spp. and Fusarium spp., which are commonly found in the environment, pose a serious global health problem. This study aims to present the results of epidemiological studies, including clinical cases, on the relationship between human exposure to some mycotoxins, especially zearalenone and aflatoxin, and the occurrence of reproductive disorders. In addition, examples of methods to reduce human exposure to mycotoxins are presented. In March 2023, various databases (PubMed, Google Scholar, EMBASE and Web of Science) were systematically searched using Google Chrome to identify studies evaluating the association between exposure to mycotoxins and the occurrence of complications related to impaired fertility or cancer incidence. The analysed data indicate that exposure to the evaluated mycotoxins is widespread and correlates strongly with precocious puberty, reduced fertility and increased cancer incidence in women and men worldwide. There is evidence to suggest that exposure to the Aspergillus mycotoxin aflatoxin (AF) during pregnancy can impair intrauterine foetal growth, promote neonatal jaundice and cause perinatal death and preterm birth. In contrast, exposure to the Fusarium mycotoxin zearalenone (ZEA) leads to precocious sexual development, infertility, the development of malformations and the development of breast cancer. Unfortunately, the development of methods (biological, chemical or physical) to completely eliminate exposure to mycotoxins has limited practical application. The threat to human health from mycotoxins is real and further research is needed to improve our knowledge and specific public health interventions.

High-risk sexual behavior consists of activities and habits that put a person at increased risk of sexually transmitted infections (STIs) or unplanned pregnancy. Poland is currently experiencing a problem with increased STI rates, largely due to poor sexual education. Our exploratory study aims to evaluate the sexual behavior of students attending universities across Poland. The study covered 7678 students from 50 different faculties and universities across the country. The authors created an original questionnaire which consists of 31 questions which, among others, included demographic factors, sexual initiation, high-risk sexual behavior, STI’s and religious beliefs. 78% of students have participated in sexual activity, among them 19% of students had ‘casual sex’ consisting of intercourse without the use of a condom, 27% had participated in sexual intercourse after the consumption of alcohol. Our study found that students who are influenced by religious belief tend to engage in sexual activity into their later years. The groups most exposed to the consequences of risky sexual behavior are mostly homosexual men, bisexual women, art students, and military students. Alcohol consumption is a strong factor contributing to risky sexual behavior. Sexual education in Poland should be improved.

Neurodegenerative disorders, which are currently incurable diseases of the nervous system, are a constantly growing social concern. They are progressive and lead to gradual degeneration and/or death of nerve cells, resulting in cognitive deterioration or impaired motor functions. New therapies that would ensure better treatment results and contribute to a significant slowdown in the progression of neurodegenerative syndromes are constantly being sought. Vanadium (V), which is an element with a wide range of impacts on the mammalian organism, is at the forefront among the different metals studied for their potential therapeutic use. On the other hand, it is a well-known environmental and occupational pollutant and can exert adverse effects on human health. As a strong pro-oxidant, it can generate oxidative stress involved in neurodegeneration. Although the detrimental effects of vanadium on the CNS are relatively well recognized, the role of this metal in the pathophysiology of various neurological disorders, at realistic exposure levels in humans, is not yet well characterized. Hence, the main goal of this review is to summarize data on the neurological side effects/neurobehavioral alterations in humans, in relation to vanadium exposure, with the focus on the levels of this metal in biological fluids/brain tissues of subjects with some neurodegenerative syndromes. Data collected in the present review indicate that vanadium cannot be excluded as a factor playing a pivotal role in the etiopathogenesis of neurodegenerative illnesses, and point to the need for additional extensive epidemiological studies that will provide more evidence supporting the relationship between vanadium exposure and neurodegeneration in humans. Simultaneously, the reviewed data, clearly showing the environmental impact of vanadium on health, suggest that more attention should be paid to chronic diseases related to vanadium and to the assessment of the dose–response relationship.

Food contamination with mycotoxin-producing fungi increases the risk of many diseases, including neurological diseases closely related to the neurotoxicity of these toxins. Based on the latest literature data, we presented the association of common Fusarium mycotoxins with neurological diseases. Articles from 2001 to 2024 were analyzed. The mechanisms underlying the neurotoxicity of the described mycotoxins were presented. They are mainly related to the increase in oxidative stress in neuronal cells, which leads to higher levels of pro-inflammatory cytokines as IL-1β, IL-6 and TNF-α, enzymatic activity as GST, GPx, CAT and SOD and neurotransmitter dysfunction (5-HT, serotonin, dopamine and GABA). At the end of the article, based on the literature data, we attempted to present ways to mitigate mycotoxin neurotoxicity using mainly natural substances of plant origin. The data in this review focus on the Fusarium mycotoxins most frequently found in food and will be useful as comparative information for future studies. It is important to conduct further studies to mitigate the neurotoxic effects of Fusarium mycotoxins in order to reduce the development of diseases of the nervous system.

Peripartum cardiomyopathy (PPCM) is a condition with an incompletely understood etiology, although many risk factors for this disorder have been mentioned. Preeclampsia (PE) is a rare but undoubtedly very important cause of PPCM. Early recognition and prompt treatment of preeclampsia and peripartum cardiomyopathy are essential to optimize pregnancy outcomes. An extensive manual search of major electronic databases was conducted in November 2021. The following literature review provides a comprehensive discussion of peripartum cardiomyopathy and preeclampsia and quantifies the prevalence of PE in women with PPCM. The authors highlighted aspects such as epidemiology, risk factors, cardiovascular changes, diagnosis and clinical presentation, and management and complications. Accumulating data indicate that both conditions have a similar pathogenesis characterized by vascular abnormalities. In both conditions we can observe an increase in interleukin-6 and gamma interferon, CCL2/MCP1, and decreased SOD activity. sFLT1 (a soluble form of fms-like tyrosine kinase 1), a substance with antiangiogenic and probably cardiotoxic effects, may be important. Preeclampsia and peripartum cardiomyopathy are characterized by recurrence rates that follow a similar pattern in subsequent pregnancies, and mortality remains a concern. Our analysis highlights the need to better understand the co-morbidity of PE and PPCM, and the need to qualify patients for the same clinical trials because of the common origin of these conditions.

Neurodegenerative diseases, characterized by neuron loss, are a group of neurological disorders that adversely affect the lives of millions of people worldwide. Although several medicines have been approved for managing neurodegenerative diseases, new therapies allowing for a significant slowdown in the progression of neurodegenerative syndromes are constantly being sought. Magnesium (Mg), a crucial mineral necessary for the functioning of organisms, is important to normal central nervous system (CNS) activity. Although the effects of this bioelement on the CNS are relatively well recognized, its role in the pathophysiology of neurological disorders in humans is not yet well characterized. Therefore, the main goal of this review is to collect data about a possible association between Mg and neurodegenerative disorders such as Alzheimer’s disease (AD), Parkinson’s Disease (PD), and Amyotrophic lateral sclerosis (ALS) in humans. Hence, the levels of Mg in blood, cerebrospinal fluid (CSF), urine, and hair from subjects with AD, PD, and ALS are compiled to detect possible variations in the levels of this mineral in the biological specimens of people with neurodegenerative illnesses. Additionally, the findings from an animal model are summarized to offer the reader a deeper insight into studies on Mg in the context of neuroprotection and neurodegeneration. Data provided in the present review indicate that Mg, due to its neuroprotective, antioxidant, anti-inflammatory, and mitochondrial-supportive properties, could be a potential therapeutic agent for AD, PD, and ALS. However, more epidemiological studies with standardized methods of dietary assessment and Mg measurement are necessary to recognize its exact role in neurodegenerative disorders. Moreover, extensive well-designed clinical trials are also needed to establish definitive therapeutic protocols and optimal dosages, and to ensure long-term safety of this mineral supplementation in AD, PD, and ALS patients.
