Germline HOXB13 mutation p.G84E do not confer an increased bladder or kidney cancer risk in polish population

Introduction The role of HOXB13 in bladder and renal tumorigenesis is unclear. Our goal was to determine the prevalence of HOXB13 p.G84E mutation in bladder and kidney cancer patients from Poland. Materials and methods 1418 patients with bladder cancer and 813 cases with kidney cancer and 4497 controls were genotyped for HOXB13 p.G84E. Results p.G84E mutation of HOXB13 gene was detected in three of 1418 (0.2%) bladder cancer cases and in six of 4497 controls (odds ratio [OR], 1.6; 95% CI 0.39–6.36; p = 0.8). Among 813 kidney cancer cases HOXB13 mutations was reported in three patients (0,4%) (odds ratio [OR], (OR = 2,8; 95% CI 0.69–11.11; p = 0.3). In cases with mutations in the HOXB13 gene, the family history of cancer was negative. Conclusion HOXB13 mutation was not associated with bladder or kidney cancer. Mutation p.G84E in HOXB13 seem not to play a role in bladder and kidney cancer development in Polish patients.

Red Spot on the European Green Map: Will the Extra Catastrophic Phenomenon Take the Polish Poaching-Pressured Ospreys to the Brink of Extinction?

Poland is the only European country where the Osprey population is declining due to the mortality of adult birds from poaching, which impacts not only single breeding attempts but also the Lifetime Reproductive Success (LRS) of specimens. However, what if there came an extra mortality factor in the moment of the lowest numbers of Osprey, already vulnerable in the country? In the years 2018–2020, we installed 22 trail cameras and five digital cameras (live online video feeds) on the nests. The total failure level observed in cameras (18.5%) was high. We observed, using these cameras, the extra mortality of chicks (10.7% of potentially fledged chicks) and even adult birds by unexpected predation by Northern Goshawk and White-tailed Eagle. This phenomenon is also common in the national population, as we found a total of ten cases of total losses by predators (eight or nine of them were birds of prey), including nests not covered by camera monitoring. The extra adult-predation by Goshawks means an extra drop in LRS. Those adult and chick predations are an example of exceptional catastrophic phenomena, which have been described as the direct cause of the extinction of animal populations throughout history. Only active conservation and stop poaching of the Polish population could stop the decline and save the Polish Ospreys.

Common ALDH3A1 Gene Variant Associated with Keratoconus Risk in the Polish Population

Background: ALDH3A1 protein is important in maintaining corneal physiology and protecting the eye from UV damage. However, none of the genome-wide association studies has indicated that the ALDH3A1 locus is associated with keratoconus. In this study, we examined the potential role of ALDH3A1 variants as risk factors for keratoconus incidence and severity in a large group of Polish keratoconus patients. Methods: In the first stage we analyzed the coding region sequence of the ALDH3A1 in a subgroup of keratoconus. Then, we genotyped three selected ALDH3A1 variants in a larger KC group of patients (n = 261) and healthy controls (n = 317). Results: We found that the rs1042183 minor allele A is a risk factor for keratoconus in the dominant model (OR = 2.06, 95%CI = 1.42–2.98, p = 0.00013). The rs2228100 variant genotypes appear to be associated with an earlier age of KC diagnosis in the Polish population (p = 0.055 for comparison of three genotypes and p = 0.022 for the dominant inheritance model). Conclusions: The rs1042183 variant in ALDH3A1 is associated with keratoconus risk in the Polish population. The differences in the allele frequency between both populations could be partially responsible for the difference in the disease prevalence.

An association study of the HSPA8 gene polymorphisms with schizophrenia in a Polish population

Heat shock cognate 70 (HSC70/HSPA8) is considered to be a promising candidate gene for schizophrenia (SCZ) due to its many essential functions and potential neuroprotective properties in the CNS (e.g., HSC70 is involved in the turnover of the synaptic proteins, synaptic vesicle recycling, and neurotransmitter homeostasis). An alteration in the expression of HSPA8 in SCZ has been reported. This implies that the genetic variants of HSPA8 might contribute to schizophrenia pathogenesis. The present study attempted to determine whether HSPA8 polymorphisms are associated with a susceptibility to schizophrenia or whether they have an impact on the clinical parameters of the disease in a Polish population. A total of 1066 participants (406 patients and 660 controls) were recruited for the study. Five SNPs of the HSPA8 gene (rs2236659, rs1136141, rs10892958, rs1461496, and rs4936770) were genotyped using TaqMan assays. There were no differences in the allele or genotype distribution in any of the SNPs in the entire sample. We also did not find any HSPA8 haplotype-specific associations with SCZ. A gender stratification analysis revealed that an increasing risk of schizophrenia was associated with the rs1461496 genotype in females (OR: 1.68, p < 0.05) in the recessive model. In addition, we found novel associations between HSPA8 SNPs (rs1136141, rs1461496, and rs10892958) and the severity of the psychiatric symptoms as measured by the PANSS. Further studies with larger samples from various ethnic groups are necessary to confirm our findings. Furthermore, studies that explore the functional contribution of the HSPA8 variants to schizophrenia pathogenesis are also needed.

Functional capacity and risk of frailty syndrome in 85-year-old and older women living in nursing homes in Poland

Maintaining sufficient physical fitness to prevent any limitations in performing activities of daily living and to be functionally independent is of great importance for both longevity and quality of life in older adults. Aim of the study was to evaluate functional physical fitness of women aged 85 years and older, residents of nursing homes, in the Polish population and to assess the risk of frailty syndrome. The study involved 17 women aged 85 years or older, residents of nursing homes in the Lower Silesian voivodeship. The Senior Fitness Test was used to assess functional fitness. The results of functional fitness tests were related to the standards for the elderly population in Poland and to the reference standards for maintaining independence. In addition, hand grip strength level was measured using a hand dynamometer, height and weight were measured, and BMI was calculated. 15-item version of the Geriatric Depression Scale was used to assess the level of depression. We used 3 of the 5 proposed criteria from the Cardiovascular Health Study Frailty Index to assess the presence of frailty syndrome: gait speed, level of hand grip strength, and the presence of depression. The results of the Senior Fitness Test demonstrate the low level of functional fitness of female nursing home residents. A large percentage of the women surveyed are below the standard values developed for Polish seniors. The weakest results were in the timed up and go test, with more than 94% of the women tested falling outside the standard ranges. The mean results of all samples do not meet the developed reference standards for maintaining independence. No non-frail person was found among the study participants and the vast majority were at risk for frailty syndrome. Most of the studied women do not meet functional fitness standards developed for the Polish population, as well as reference standards for maintaining independence. Nursing home residents over the age of 85 are at risk for frailty syndrome.

The Volhynian mass murders of 1943 in Polish-Ukrainian historical discussions in the 1990s

The article analyzes the first public discussions of the last decade of the 20th century about mass murders of Polish population in Volhynia in 1943. The author explores the emergence of the topic of “Volhynia” in the public space and Polish-Ukrainian historical debates about these mass murders in the 1990s. The research is based on the published sources and interviews with the participants in the Polish-Ukrainian dialog. The article focuses on the first mentions of the Volhynian events in the post-communist period, on the way this issue was discussed at seminars of Polish and Ukrainian historians, and in the leading Polish newspapers “Gazeta Wyborcza” and “Rzeczpospolita”. Particular attention is paid to the discussion about the mass murders in the “Gazeta Wyborcza” in 1995. The Volhynian issue appeared in the public space after almost fifty years of silence initiated from the Polish “kres” and veteran circles which represented the victims of the mass murders. This topic was arousing interest gradually. It did not immediately take a lead- ing place in Polish-Ukrainian historical debates. In the 1990s, the discussion about “Volhynia” took place primarily between historians and within the groups to which this topic was important. There was only one discussion about the Volhynian events in the press, namely in the “Gazeta Wyborcza”. This newspaper, which appeared as an organ of Solidarity, pays attention especially to the relationship between Poland and its neighbours, particularly Ukraine. In the Ukrainian central media, the Volhynian issue remained completely without attention. Although the debates about “Volhynia” were not actively conducted in the 1990s, certain tendencies were established during this period, which remained characteristic in the following years. In Poland, these events were perceived as one of the most traumatic episodes of the national history, so it was the Polish side who initiated the discussions about this topic. The Ukrainian side was forced to respond to these initiatives.

Exploring the effects of birth order on human lifespan in Polish historical populations, 1738–1968

While the relationships between birth order and later outcomes in life, including health and wealth, have been the subject of investigation for several decades, little or no data exist regarding the relationship between birth order and life expectancy in the Polish population. The aim of this study was to explore the link between birth order and lifespan in Polish historical populations. We obtained 8523 records from a historical dataset that was established for parishioners from the borough of Bejsce, including 4463 males and 4060 females. These data pertain to the populations that lived over a long period in a group of localities for which parish registers were well preserved. The Mann-Whitney U test, the Kruskal-Wallis ANOVA and ANCOVA were run. The results strongly suggest that birth order affects male longevity. However, no such association was found for females. On balance, the hypothesis that first-born boys live longer because they are born to relatively younger parents has received some empirical support and deserves further study. We hypothesise that the effects of birth order on human health and lifespan might be overshadowed by other factors, including educational attainment, socioeconomic status and lifestyle.

The policy of the Polish authorities towards national and ethnic minorities after 1989

The aim of this article is to analyse the Polish authorities’ policy towards national and ethnic minorities after 1989, after the collapse of real socialism in Poland. The author gives an overview of the historical and sociopolitical situation of these minorities in Poland. The main point of consideration is the position and functioning of national and ethnic minorities on the basis of law, their political activity in parliamentary and local elections, as well as the attitude of leading Polish political parties towards the issues of national and ethnic minorities. National and ethnic minorities are, by definition, less numerous than the rest of the Polish population, but remain Polish citizens and at the same time are aware of their historical community. The article uses the following methods: descriptive and institutional-legal.
