Research into the neurobiological origins of same-sex attraction is inconclusive. A recent theory of homosexuality posited that maternal thyroid dysfunction during pregnancy is associated with an increased rate of homosexual orientation in offspring. Relevant studies from the prenatal thyroid model perspective were reviewed, the major findings of which are as follows: i) An increased prevalence of Hashimoto's disease in lesbian women suggests a maternal and even familial presence of the same autoimmune thyroid disease. Female-to-male transsexuals and lesbian women were also reported to have higher rates of polycystic ovary syndrome (PCOS). Over the last several years, reports suggesting a strong link between PCOS and thyroid autoimmunity have accumulated. ii) The increased risk of autism spectrum disorders (ASD) in the offspring of mothers with thyroid autoimmunity in pregnancy and the association between ASD and gender dysphoria indicate a link between maternal thyroid dysfunction and gender dysphoria/same-sex attraction in the off-spring. iii) The high risk of miscarriage and retarded fetal growth in pregnancies of mothers who give birth to homosexual off-spring can be explained by the impact of maternal thyroid dysfunction during pregnancy. This perspective review highlights relevant research findings and integrates them into the prenatal thyroid model of homosexuality. A better understanding of the mechanisms involved in the generation of same-sex orientation will contribute to the betterment of individual lives, as well as of society.

The prevalence of thyroid abnormalities among 831 sexual, violent, and non‐violent non‐sex offenders was found to be greater than found in the general population. Thyroid abnormalities were most common among violent offenders and among sex offenders who victimized children. Thyroid disorders were associated with psychotic diagnoses, delusions, mania, suicidal thoughts, and showed a trend to more suicide attempts. These disorders were undiagnosed in 49.1% of the cases prior to the present clinical assessment. Of these, 59.3% faced their first criminal charges, and the undiagnosed thyroid abnormalities may be important in the offenders’ treatment and may be possible legal mitigating factors in some offenses. Results indicate that a routine endocrine evaluation with blood tests would be a valuable addition to the assessment of violent and sexual offenders.

This article focuses on the assessment of thyroid hormones in 64 pregnant women in Mauritius. Our study revealed that serum thyroid‐stimulating hormone was significantly raised in four pregnant women with normal serum‐free tri‐iodothyronine and serum‐free thyroxine. It was also noted that mean serum‐free tri‐iodothyronine was non‐significantly much lower in the pregnant women. It is concluded that the four pregnant women with an abnormally elevated serum thyroid‐stimulating hormone together with normal free thyroid hormones probably have subclinical hypothyroidism.

This case looks at South African fitness Instapreneur Candice Bodington and how her business trajectory unfolded at the same time of the successful Australian Kayla Itsines. The case begins with Bodington considering options for her brand in January 2020. Following her business, Candibod’s, fast initial growth via Instagram, the case tracks its development while also glancing at the enormous success of Itsines and her Sweat with Kayla app. However, as Bodington faces her own health care, the future and next steps of a brand built on social media becomes less certain. The case ends just a few months later with the unfolding effects of Covid-19 and a whole new host of uncertainties, especially in the fitness industry and Bodington having to reconsider her brand’s options.

The learning outcome of this paper is as follows: to understand the challenges of building an online brand. To evaluate the effect of brand communities as a growth strategy. To analyse the impact of social media platforms as a brand-building tool. To critically assess the effect of changing industry dynamics and technology on consumer behaviour. To evaluate how brands can navigate the negative implications of social media. To understand brand differentiation. To understand the strategic decisions associated with brand repositioning.

An unambiguous and agreed definition of what a functional food is does not exist. However, broadly speaking, a food is said to be functional if it contains a food component which affects one or more targeted functions of the body in a positive way. Functional foods often fall into the grey area between foods and medicine, but from a regulatory standpoint they are foods and consequently subject to food regulations. According to the food labelling directive, it is not permitted to label a food in such a way that, first, it will attribute the property of preventing, treating and curing human disease, or refer to such properties, and second, that it can mislead the consumer. The first aspect refers to the claims a food product may carry and specifically prohibits health claims – even if scientifically valid. It is argued that a claim on a food is a health claim if the consumer perceives it as such. The second aspect states that a given claim must be validated by sufficient scientific evidence, and far too often associations between food intake and disease risk have been misinterpreted as causal relations.

Both youngsters and adults with same-sex attraction are at greater risk for negative health outcomes. Despite mounting efforts to determine the biological background, a satisfactory conclusion has not been reached and there is a need to explore alternate factors like functioning of thyroid system during pregnancy. A retrospective chart review was undertaken of 790 eligible children and adolescents who had been admitted to child psychiatry between 2005 and 2013. This population consisted of 520 (65%) males and 270 (35%) females, aged 8 to 17 years. Fifteen mothers (1.8%) were found to have a history of thyroid dysfunction during pregnancy. Sixteen youngsters (2%) had a history of same-sex attraction. Twelve overlapping cases with both same-sex attraction and maternal thyroid dysfunction during pregnancy were identified, which was extremely significant (P<0.0001, by Fisher's exact test). The association was also significant for each sex (P<0.0001, by Fisher's exact test). There is evidence that thyroid gland plays a crucial and decisive role in determining sexual orientation in people. Maternal thyroid dysfunctions during pregnancy may result in homosexual orientation in the off-spring.

While hypothyroidism is common in lithium-treated patients, thyrotoxicosis is rarely reported. We present a female patient on lithium for maintenance therapy of bipolar affective disorder, who developed thyrotoxicosis for few months which was followed by hypothyroidism which continued. There was no further thyrotoxicosis episode during a five year follow up period. While she was treated for thyroid dysfunction, lithium was continued. There was no clinical impact on the maintenance of the bipolar affective disorder during the follow up period; she was maintained well in the community.

This analysis of chat reference transcripts assesses differences in how librarians and graduate assistants (GAs) incorporate teaching strategies in responding to chat reference inquiries in social sciences, health sciences, humanities, STEM and business/economics at a large, public R1 university in the United States.

Researchers with disciplinary assignments in five different subject domains conducted qualitative analysis of a purposive sample of 982 transcripts of chat interactions during four semesters in 2021 and 2022.

Some form of information literacy instruction (ILI) occurred in 58% of the transcripts, with slightly less teaching occurring in social sciences inquiries than in other subject areas. Of transcripts that included teaching strategies, search procedures predominated, followed by a mix of concepts and procedures, and the least with concepts only. Chat providers taught concepts specific to social sciences, health sciences and humanities, but not to STEM or business.

The study compares transcripts at one institution; findings may be most applicable to large, research institutions that seek to incorporate ILI in online reference services.

Chat reference training should include best practices for ILI relevant to specific subject domains for providers without background in those disciplines and recommendations for referrals to subject specialists.

Existing ILI literature does not address the question of how chat providers teach concepts rooted in a specific subject domain or offer a comparison of teaching strategies employed in different disciplines, by librarians versus GAs or staff.

Supporting the mental health of university students is a key priority for higher education. Students living with long-term health conditions are at increased risk of poor mental health; yet little work has focused on their particular mental health needs or indeed, the implications for health education in the university setting. This study sought to identify the mental health support needs of students with long-term conditions, including best ways for universities to support these students.

A UK national online survey of 200 university students living with long-term physical health conditions (e.g. asthma, endometriosis, epilepsy) was conducted in 2019.

95% of respondents reported that their long-term condition/s had at least a moderate impact on their mental wellbeing, with 81% reporting that they felt depressed and anxious at least once a month because of their health. The most common suggestion for how universities can better support their mental wellbeing was to raise awareness about long-term conditions on campuses, with many reporting a lack of understanding about long-term conditions from academic and support services staff members – with negative impacts on their mental health. Because of this, some respondents reported a reluctance to come forward and seek help from university services, with 25% not formally disclosing their conditions.

These reported concerns underscore the need to develop health education amongst university staff about long-term conditions and to ensure these students are supported with their health at university.
