This review provides an overview of cannabis-based phytocannabinoids, focusing on their mechanisms of action, therapeutic applications, and production processes, along with the environmental factors that affect their quality and efficacy. Phytocannabinoids such as THC (∆⁹-tetrahydrocannabinol), CBD (cannabidiol), CBG (cannabigerol), CBN (cannabinol), and CBC (cannabichromene) exhibit significant therapeutic potential in treating various physical and mental health conditions, including chronic pain, epilepsy, neurodegenerative diseases, skin disorders, and anxiety. The cultivation of cannabis plays a crucial role in determining cannabinoid profiles, with indoor cultivation offering more control and consistency than outdoor methods. Environmental factors such as light, water, temperature, humidity, nutrient management, CO₂, and the drying method used are key to optimizing cannabinoid content in inflorescences. This review outlines the need for broader data transfer between the health industry and technological production, especially in terms of what concentration and cannabinoid ratios are effective in treatment. Such data transfer would provide cultivators with information on what environmental parameters should be manipulated to obtain the required final product.

The Valsalva maneuver, named after Antonio Maria Valsalva, is one of the vagal maneuvers. It is defined as a forced expiration against a closed glottis, leading to an increase in intrathoracic and intra-abdominal pressure. Over the years it has become a subject of interest to many clinical researchers who have comprehensively studied its physiology and clinical significance. As a result, the application of the Valsalva maneuver has expanded to become a versatile technique applied across a wide range of medical specialties as a diagnostic and therapeutic tool. Additionally, it has found its use in sport among athletes. The aim of this article is to present the current state of knowledge about the clinical significance of the Valsalva maneuver and show that this simple physiological technique described in the 18th century remains a valuable tool in modern clinical practice and has found its use in sport. The review was based on chosen literature obtained from the PubMed electronic database, Google Scholar electronic database, and other scientific articles. Search terms included keywords listed below. Keywords: Valsalva maneuver; vagal maneuver; respiratory maneuver; autonomic system

Injuries in combat sports can happen to any athlete, regardless of gender, age, training experience or whether he or she is an amateur or a professional. The range of injuries varies from superficial, short-term damage to severe injuries with serious consequences, including death. There are many types of combat sports, each with different rules and specific injuries. Amongst various divisions of combat sports, one of the basic ones is the division into ground and stand-up sports. In the following work, using the available literature, we wanted to present the specifications of several of the most popular combat sports and compare their most common locations of injuries, types of injuries and mechanisms of their formation, paying attention to which of these categories a given sport belongs to. We also discuss differences in the rate of injury for different age, genders, prevalence of injuries during situations of practice and competition. In the end, it is presented what are the possible long-term complications of injuries in combat sports and which actions such as protective gear, bans on certain techniques or behavioural changes might reduce the injury rate to protect the athletes health, well-being and decrease the economic burden on healthcare systems.

Background: Psychosis is defined as a series of symptoms that impair the mind and lead to a kind of loss of reference to reality. Development of psychosis is usually preceded by the appearance of prodromal symptoms. Numerous attempts have been made to find out how psychoactive substances can influence the onset and development of psychotic disorders, but to date there are no studies that show a link between the onset of prodromal symptoms and the use of psychoactive substances. Methods: A survey consisting of epidemiological and demographic questions, the Drug Use Disorders Identification Test (DUDIT), and the Prodromal Questionnaire Brief Version (PQ-B) was conducted on social media among users of illegal psychoactive substances, covering 703 study participants. Results: A total of 39.8% of the respondents had been treated by a psychiatrist, and the most popular drugs used by respondents in their lifetime were tetrahydrocannabinol-containing products, MDMA, amphetamines, and LSD. A significant correlation was found between the DUDIT and the PQ-B values. Conclusions: Intensity of psychoactive substance use correlated positively with the risk of appearance and intensity of prodromal symptoms of psychosis. Early exposure to psychoactive substances increased the risk of heavy substance use in adulthood and led to more frequent prodromal states.

Introduction: Due to the increasing number of cases and the levels of mortality, colorectal cancer is still a major health problem. Therefore, the growing interest in the quality of life of patients and the assessment of the quality of life of patients with colorectal cancer seems to be particularly important. The aim of the study was to investigate and determine factors that have a significant impact on the QoL of patients who were diagnosed with colorectal cancer that was surgically treated in the Surgical Department of the 4th Military Clinical Hospital in Wroclaw. Methods: 102 respondents were enrolled into the study. The QLQ-C30, QLQ-CR29 as well as an original questionnaire regarding the socioeconomic factors were used for the assessment. The information was supplemented with patients’ clinical data. Results: According to the QLQ-C30 questionnaire the average QoL of the respondents was 55%. Factors such as male gender, younger age, higher BMI, no significant weight loss, living with family, lower level of education and being professionally active have significant positive impact on QoL. In contrary, patients with more advanced and malignant cancer with tumor located in the right half of the colon had worse QoL. The particular domains of QoL influenced by these factors were also identified. Determining these factors will allow for more effective treatment, for the shortening of the hospitalization and finally for the reduction of the costs. Conclusion: The better QoL of the patients with colorectal cancer treated surgically showed younger men, living with family and with the support from close people, professionally active, with primary level of education, and without significant weight loss, ie less than 5% of body weight in the last 6 months. Moreover, patients with cancer located in the left colon, at a lower stage, with a lower grading demonstrated a better QoL.

Creutzfeldt-Jakob disease (CJD) is a rare condition. In this study we describe the diagnosis of the disease in a 73-year old female, presenting dementia. Diagnostic tests unveiled characteristic features of CJD. The diagnosis of CJD was confirmed. It is important to always take into consideration the diagnosis of CJD in the diagnostic process of dementia. Purpose: The aim of this scientific paper is to present symptoms and diagnostic methods of Creutzfeldt-Jakob disease on the basis of a clinical case. Review Methods: We conducted our study as a literature review based on information gathered from PubMed, Embase, GoogleScholar using combinations of the following. As a part of study, we also present a case description from our materials from clinical practice.
