Abstract
A theoretical perspective on grandiose narcissism suggests four forms of it (sanctity, admiration, heroism, rivalry) and states that these forms conduce to different ways of thinking and acting. Guided by this perspective, we examined in a multinational and multicultural study (61 countries; N = 15,039) how narcissism forms are linked to cognitions and behaviors prompted by the COVID-19 pandemic. As expected, differences in cognitions and behaviors across narcissism forms emerged. For example, higher narcissistic rivalry predicted lower likelihood of enactment of COVID-19 prevention behaviors, but higher narcissistic sanctity predicted higher likelihood of enactment of COVID-19 prevention behaviors. Further, whereas the heroism, admiration, and rivalry narcissism forms acted in a typically antisocial manner, with high narcissism predicting greater endorsement of unfounded health beliefs, the sanctity form acted in a prosocial manner, with higher narcissism being linked to lower endorsement of unfounded COVID-19 health beliefs. Thus, the findings (a) support the idea of four narcissism forms acting differently, and (b) show that these differences reflect a double-edged sword, sometimes linking to an anti-social orientation, and sometimes linking to a pro-social orientation.

Horvat M, Pavan Jukić D, Marinović L, Bursać D, Ribić R, Neuberg M, Bursać D. Prevalence of Primary Dysmenorrhoea and Its Impact on Academic Performance among Croatian Students during the COVID-19 Pandemic. Obstet Gynecol Int 2023; 2023:2953762. [PMID: 37304995 PMCID: PMC10257551 DOI: 10.1155/2023/2953762] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2023] [Revised: 03/21/2023] [Accepted: 05/16/2023] [Indexed: 06/13/2023] Open
Abstract
Background Dysmenorrhoea is one of the most common gynaecological problems. Therefore, it is important to investigate its impact during the COVID-19 pandemic which has a great impact on the lives of menstruating people all over the world. Aim To determine the prevalence and impact of primary dysmenorrhoea on academic performance among students during the pandemic. Materials and Methods This cross-sectional study was conducted in April 2021. All data were collected by an anonymous self-assessed web-based questionnaire. Due to voluntary participation in the study, 1210 responses were received, but 956 were left for analysis after exclusion criteria were applied. Descriptive quantitative analysis was performed and Kendall rank correlation coefficient was used. Results The prevalence of primary dysmenorrhoea was 90.1%. Menstrual pain was mild in 7.4% of cases, moderate in 28.8%, and severe in 63.8%. The study found that primary dysmenorrhoea has a great perceived impact on all included aspects of academic performance. Most affected were concentration in class in 810 (94.1%) and doing homework and learning in 809 (94.0%) female students. There is also a correlation between menstrual pain intensity and its impact on academic performance (p < 0.001). Conclusions Our study found that the prevalence of primary dysmenorrhoea among students at the University of Zagreb is high. Painful menstruation greatly impacts academic performance and therefore it is important to do more research on this topic.

Abstract
The aim of the study was to investigate the sexuality of individuals undergoing in vitro fertilization as one of the methods of infertility treatment. The focus was on sexual dysfunction, sexual satisfaction and associated risk factors. Data were collected based on a validated, standardized procedure. The sample consisted of 119 individuals who had undergone in vitro fertilization, 61 (51.3%) women and 58 (48.7%) men, average age 35 years. Most of the 119 survey participants were in the 31-35 age group (37%), married (79.8%), with high school diploma (51.3%), Catholic denomination (89.9%), childless (78.2%), with a one sexual partner in their lifetime (51.3%), and in current sexual relationship for a period of 7 to 8 years (18.5%). The survey found statistically significantly higher satisfaction among male participants, participants in the 26-30 age group, those with a higher level of education, nonreligious, without children in marriage, with four sexual partners in life, over a period of 1 to 2 years in current partner (sexual) relationship, and without a diagnosed sexual disorder. There was a correlation between infertility, associated treatment, and sexuality. Infertility and involvement in treatment procedures increased the risk of sexual dysfunction. The risk factors identified in our study could help facilitate detection and timely treatment of sexual dysfunction, which would help maintain healthy sexuality in couples participating in in vitro fertilization procedures.

Abstract
Aging interventions will be ineffective if we do not understand the basic principles of aging. Currently, there is no consensus on the issue whether aging is programmed or not. The hypothesis presented in this article indicates that aging (at least graying of male hairs) is programmed. This hypothesis is supported by the symmetry of the graying of male beard hairs. According to stochastic theories of aging, aging is a passive non-programmed process where random dispersion of graying hairs should result. On the contrary, programmed theories of aging would predict that there should be symmetry on the left and right parts of the face showing the same proportion, pattern and time of appearance of graying hairs.

Abstract
The role of T regulatory lymphocytes (Treg) particularly in cancer is well known. The goal of the present study was to determine the contribution of these lymphocytes in the regulation of anti-tumor immunity of CBA/HZgr mice against MC-2 fibrosarcoma (4th generation of methylcholanthrene induced tumor). The levels of T lymphocytes (CD4+, CD8+ and CD4+CD25+) were determined 8 and 20 days after tumor transplantation. Further, the role of CD4+CD25+ (Tregs) in tumor-host interaction was evaluated in vitro and in vivo by using specific monoclonal antibodies. We found that splenocytes of both control and Treg depleted tumor bearing mice strongly but differently inhibited growth of tumor cells in vitro. While splenocytes of untreated mice exhibited significant decrease of this activity (from 74.4% to 62.6% and 32.95%), the splenocytes of Treg depleted mice showed increase of this activity (from 79.5% to 84.3% and 86.2%) from day 6 to day 13 and day 21 after tumor grafting, respectively. Further, upon i.v. injecting specific monoclonal anti-Treg antibody tumor immediately prior to tumor cell intracutaneous transplantation, the tumor was rejected after initial growth. In treated mice, the incidence of Treg cells was very low initially, reaching normal values two weeks later. These animals were shown to be resistant to tumor transplantation four months later.

Abstract
This review article is focused on the impact of antioxidants and prooxidants on health with emphasis on the type of antioxidants that should be taken. Medical researchers suggest that diet may be the solution for the control of chronic diseases such as cardiovascular complications, hypertension, diabetes mellitus, and different cancers. In this survey, we found scientific evidence that the use of antioxidants should be limited only to the cases where oxidative stress has been identified. This is often the case of specific population groups such as postmenopausal women, the elderly, infants, workers exposed to environmental pollutants, and the obese. Before starting any supplementation, it is necessary to measure oxidative stress and to identify and eliminate the possible sources of free radicals and thus increased oxidative stress.

Abstract
This study aimed to investigate whether infertility and its treatment affect couple sexuality. A systematic literature review was performed, focusing on female and male sexual dysfunctions due to infertility. The method was descriptive, using a meta-synthesis of scientific research published between 2012 and 2017 in the English language. The search for suitable studies was carried out with the research databases Medline, CINAHL, PubMed and ScienceDirect using the following keywords: infertility, sexual dysfunctions, couple. It can be concluded that infertility negatively affects the sexuality of an infertile couple, which is further proven by a high percentage of sexual dysfunctions (43%-90% among women and 48%-58% among men). Couples report less satisfaction with sexuality. Since lower satisfaction and dysfunctions are closely connected with infertility and its treatment, couples might benefit from sexual therapy and support during the process of infertility treatment. Further research should focus on the evaluation of different psychological interventions that would address sexuality in couples when diagnosed and treated for infertility.
