South Africa has six species of primates, three of which are bushbabies (family Galagidae). Very little information is available on their parasites due to the lack of longitudinal studies, although Rhipicephalus appendiculatus, Amblyomma hebraeum and Haemaphysalis elliptica were previously reported from the brown greater galago (Otolemur crassicaudatus) in South Africa. During 2014–2019, 83 O. crassicaudatus (70 live-trapped and 13 deceased animals) were checked for the presence of hard ticks, all from Limpopo Province, South Africa. Seventy-three of 83 (88 %) galagos were found to be tick-infested. Among ixodid genera, Haemaphysalis had the highest prevalence (46 % of the bushbabies), followed by Rhipicephalus (25 %) and Ixodes (18 %). In total, ten tick species were identified. Importantly, all infestations were monospecific. Ticks occurred on various body parts of bushbabies, thus no predilection site was noted. In conclusion, while previously only three ixodid species were known to infest bushbabies in South Africa, the present study showed that these animals can be parasitized by a much broader range of hard ticks.

Neurofibromatosis is a genetic disease inherited in an autosomal, dominant manner. The course of von Recklinghausen’s disease varies from patient to patient. Most cases are mild and uncomplicated. The diagnosis of NF1 is based on the criteria of the National Institutes of Health (NIH). Type 2 neurofibromatosis is inherited, in most cases autosomal dominantly. The abnormal allele can be inherited from either parent, with the risk of passing the gene on to the offspring from the parent, being 50%. This article describes the familial form of neurofibromatosis. In the case in question, all three sisters were found to be mutated in the NF1 gene by genetic testing. In the same family, the clinical manifestation of the disease may be different for sisters and children. Due to compliance with medical recommendations, the disease does not significantly affect the quality of life of the families affected.

The review focuses on the practical work of "Poor Queer Studies." Rather than retheorize queer studies from the class perspective of "rich" and "poor," Brim makes a case study of his work as a professor of queer studies at the College of Staten Island (CSI). Insisting on the particularity of his and his students’ relationship to queer studies, Brim makes an example of the work they do together in the classroom, and the ways they live their studies on public transit, at home with their families, and in their part-time jobs. This review questions the extent to which poor queer studies differs from the modern university’s reduction of all education to career-training. Brim’s praxis of poor queer studies is always undertaken with individual students in specific socio-economic circumstances—a particularity that makes it different than market-driven job-training. This review also raises questions about the general applicability of this case study. Would poor queer studies work elsewhere as it does at CSI? Berlant’s idea of exemplarity is helpful in answering this question. Unlike examples that confirm a norm, there are examples that change norms. Brim’s example of poor queer studies works to exemplarily change what counts as normal. Practically, this means no longer thinking of queer studies as operating without class distinction—and reclaiming part of the work of the discipline from seemingly classless rich queer studies at places like Yale and New York University.

The paper focuses on Michel Foucault's early monograph, Maladie Mentale et Psychologie (1954/62); specifically the focus is on the issue of anxiety, which Foucault treats as central to pathological signification. Through a close reading of the text of Maladie Mentale and a comparison of the work to interpretive trends in French psychoanalytic theory in the 1950s and 1960s, the paper argues that anxiety as a discursive phenomenon overruns psychological discourse as well as Foucault's own theoretical engagement of such discourse. In conclusion, the paper finds that the voice of unreason Foucault detects in psychological discourse is the anxiety of theory confined within the limits of individual psychology.

The paper reconsiders the events of May 1968 in light of the various attempts to explain and theorize the politics of the student revolution in France. Drawing on contemporary accounts of May '68 as well as historical reflections on the revolution, the paper constructs a historically and politically "horizontal" theory; the structure of the barricades is used as a model for such a political theory. In the Foucauldian and Deleuzian sense of an active form of theory, a "horizontal" approach effectively politicizes theory and enables it to continue the seemingly failed efforts of the student protestors.

Study Question: Is the outcome of donor recruitment influenced by the country in which recruitment took place or the initial identity (ID)-release choice of applicants?, Summary Answer: More applicants are accepted as donors in Denmark than in the USA and those who choose ID release are more frequently accepted than those who do not., What Is Known Already: The successful recruitment of sperm donors is essential to provide a range of medically assisted reproduction (MAR) procedures, which rely upon donor sperm. However, while much has been written about the medical screening and assessment of sperm donors from a safety perspective, relatively little has been written about the process of recruiting donors and how it works in practice. There are differences in demographic characteristics between donors who choose to allow their identity to be released to their donor offspring (ID release) compared to those who do not (non-ID release). These characteristics may also influence the likelihood of them being recruited., Study Design, Size, Duration: A total of 11 712 men applied to be sperm donors at a sperm bank in Denmark and the USA during 2018 and 2019., Participants/materials, Setting, Methods: Anonymized records of all donor applicants were examined to assess the number passing through (or lost) at each stage of the recruitment process. Statistical analysis was carried out to examine differences between location (Denmark or USA) and/or donor type (ID release versus non-ID release)., Main Results and the Role of Chance: Few applicants (3.79%) were accepted as donors and had samples frozen and released for use; this was higher in Denmark (6.53%) than in the USA (1.03%) (χ2 = 243.2; 1 degree of freedom (df); z = 15.60; P < 0.0001) and was higher in donors who opted at the outset to be ID release (4.70%) compared to those who did not (3.15%) (χ2 = 18.51; 1 df; z = 4.303; P < 0.0001). Most candidate donors were lost during recruitment because they: withdrew, failed to respond, did not attend an appointment, or did not return a questionnaire (54.91%); reported a disqualifying health issue or failed a screening test (17.41%); did not meet the eligibility criteria at the outset (11.71%); or did not have >5 × 106 motile sperm/ml in their post-thaw samples (11.20%). At each stage, there were statistically significant differences between countries and the donor's initial ID choice. During recruitment, some donors decided to change ID type. There were no country differences in the frequency in which this occurred (χ2 = 0.2852; 1 df; z = 0.5340; P = 0.5933), but it was more common for donors to change from non-ID release to ID release (27.19%) than the other way around (11.45%) (χ2 = 17.75; 1 df; z = 4.213; P < 0.0001), although movements in both directions did occur in both countries., Limitations, Reasons for Caution: No information was available about the demographic characteristics of the applicants, which may also have influenced their chances of being accepted as a donor (e.g. ethnicity and age). Donor recruitment procedures may differ in other locations according to local laws or guidelines., Wider Implications of the Findings: A better understanding of when and why candidate donors are lost in the recruitment process may help develop leaner and more efficient pathways for interested donors and sperm banks. This could ultimately increase the number of donors recruited (through enhanced information, support, and reassurance during the recruitment process) or it may reduce the financial cost to the recipients of donor sperm, thus making it more affordable to those who are ineligible for state-funded treatment., Study Funding/competing Interest(s): The study received no funding from external sources.

Background: More knowledge about the long-term impact of sperm donation is essential as the donor's attitude towards donation may change over time. Personal and social developments may prompt a rethinking of previous actions and decisions, or even regret. Thus, the aim of this study was to explore the experiences and attitudes of men who were sperm donors more than 10 years ago., Methods: From May to September 2021, semi-structured, qualitative interviews were conducted with 23 former donors (> 10 years since last donation) from Cryos International sperm bank. Two participants were non-anonymous donors and 21 were anonymous. The interviews were conducted by phone or via video (mean 24 minutes). All interviews were recorded, transcribed verbatim and rendered anonymous. Data were analyzed using thematic analysis., Results: The analysis showed that most men had been donors for monetary and altruistic purposes, and now considered sperm donation as a closed chapter that was 'unproblematic and in the past'. Most men valued anonymity and emphasized the non-relatedness between donor and donor conceived offspring. Knowledge about recipients and donor offspring was seen as 'damaging' as it could create unwanted feelings of relatedness and responsibility towards them. All men acknowledged donor conceived persons' potential interests in knowing about their genetic heritage in order to understand appearance and personal traits, but also emphasized the donors' rights to anonymity. Potential breach of anonymity was generally considered 'highly problematic' as it was expected to disturb their families and force a relationship on them., Conclusion: This study reports on former donors who might not have volunteered for research due to lack of interest or protection of privacy. The majority of men valued anonymity and clearly demarcated a line between sperm donation and fatherhood, which was enforced by not knowing about the donor offspring or recipients., Competing Interests: SL, SB, MDT and IV declare no conflict of interest.

Older adults' usage of information and communication technology (ICT) is challenged or facilitated by perception of usefulness, technology design, gender, social class, and other unspoken and political elements. However, studies on the use of ICT by older adults have traditionally focused on explicit interactions (e.g., usability). The article then analyzes how symbolic, institutional, and material elements enable or hinder older adults from using ICT. Our ethnographic methodology includes several techniques with Spanish older adults: 15 semi-structured interviews, participant observation in nine ICT classes, online participant observation on WhatsApp and Jitsi for 3 months, and nine phone interviews due to COVID-19. The qualitative data were analyzed through Situational Analysis. We find that the elements hindering or facilitating ICT practice are implicit-symbolic (children's surveillance, paternalism, fear, optimism, low self-esteem, and contradictory speech-act), explicit-material (affordances, physical limitations, and motivations), and structural-political (management, the pandemic, teaching, and media skepticism). Furthermore, unprivileged identities hampered the ICT practices: female gender, blue-collar jobs, illiteracy, and elementary education. However, being motivated to use ICT prevailed over having unprivileged identities. The study concludes that society and researchers should perceive older adults as operative with technologies and examine beyond explicit elements. We urge exploration of how older adults' social identities and how situatedness affects ICT practice. Concerning explicit elements, Spanish authorities should improve and adapt ICT facilities at public senior centers and older adults' homes, and ICT courses should foster tablet and smartphone training over computers., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Gomez-Hernandez, Adrian, Ferre and Villalba-Mora.)
