Young people's views regarding participation in mental health and wellbeing research through social media

Social media is a central component in the lives of many young people, and provides innovative potential to conduct research among this population. Ethical issues around online research have been subject to much debate, yet young people have seldom been consulted to provide a youth perspective and voice. Eight (8) focus groups involving 48 Grade 9 Western Australian secondary school students aged 13-14 years were held in 2012, to investigate how young people perceive the feasibility and acceptability of social media when used as a research tool to investigate various issues relevant to their mental health and wellbeing. Whilst young people recognise many benefits of researchers using social media in this way, such as its relevance, innovation and accessibility, there were salient issues of privacy, consent, and practicality that require careful negotiation. There is a need for continued exploration and scientific debate of the moral and ethical implications of using social media for research, to help ensure this is employed in an appropriate and effective way that is respectful of and sensitive to the needs and views of young peoplepeer-reviewe

Research report: "Using what you have to get what you want": Vulnerability to HIV and prevention needs of female post‐secondary students engaged in transactional sex in Kumasi, Ghana

This study was implemented by Boston University in collaboration with the Kwame Nkrumah University of Science and Technology with support from the President’s Emergency Plan for AIDS Relief (PEPFAR) through the U.S. Agency for International Development under Project SEARCH Task Order No. GHH‐I‐00‐07‐00023‐00, beginning August 27, 2010. The content and views expressed here are the authors’ and do not necessarily reflect the opinion or policy of USAID or the U.S. Government.This report presents findings from a qualitative study examining vulnerability to HIV of female post‐secondary students engaged in transactional sex in Kumasi, Ghana and their prevention needs. The study was conducted by Boston University’s Center for Global and Health and Development (CGHD) and the Kwame Nkrumah University of Science and Technology (KNUST) as part of Project SEARCH funded by the United States Agency for International Development Ghana. Participants were recruited from five post‐secondary institutions in the greater Kumasi area. Our objective is to provide academic institutions, the Ghana AIDS Commission (GAC), the National AIDS Control Program, donors, and other stakeholders with rich data to inform research and programmatic efforts in Kumasi specifically, as well as academic institutions in general. We set out to document what forms of transactional sex female students are engaging in, who their partners are, and what motivates them to participate. We asked students about the individual and structural vulnerabilities for HIV reported by female post‐secondary students involved in transactional sex and what their prevention needs are. We also interviewed a small sample of faculty, residence hall matrons, and hotel staff to get their perspective on the behavior of female students practicing transactional sex that might put them at risk for HIV. The findings of this study can be used as well to inform the design of future studies of young women engaging in transactional sex in Ghana. With such limited understanding of HIV transmission among young female post‐secondary students engaged in transactional sex, research is needed to determine how this group contributes to the overall HIV epidemic. The Ghana AIDS Commission has recognized the need for further research among communities engaged in less well‐defined risky sex practices in the National Strategic Plan for Most‐at – Risk Populations (MARP) 2011‐2015.4 This study attempts to fill in gaps in the research regarding transactional sex, taking into account the complexities and nuances of the practice, in addition to examining the needs of female students for targeted HIV prevention programs.Support from the President’s Emergency Plan for AIDS Relief (PEPFAR) through the U.S. Agency for International Development under Project SEARCH Task Order No. GHH‐I‐00‐07‐00023‐00, beginning August 27, 201

The content and views expressed here are the authors’ and do not necessarily reflect the opinion or policy of USAID or the U.S. Government.HIV prevalence among young Ghanaian men and women aged 15–24 years old is estimated at 1.7%.1 HIV prevalence in the specific population of female post-secondary students is unknown. The Ghana AIDS Commission (GAC) recognizes the need for further research in communities participating in less well-defined risky sex practices. This study was conducted by Boston University’s Center for Global Health and Development and the Kwame Nkrumah University of Science and Technology with funding from the United States Agency for International Development/Ghana. The objective was to provide academic institutions, the GAC, the National AIDS Control Program, donors, and other stakeholders with data to inform research and programmatic efforts in Kumasi, specifically, as well as academic institutions, in general. Study participants were recruited from five post-secondary institutions in the greater Kumasi area. Data were collected on students’ perceptions of transactional sex (TS) on campus, individual and structural HIV vulnerabilities, and prevention needs through in-depth interviews with seven female post-secondary students involved in TS and focus groups with twenty-nine female and male students. Key informant interviews were also conducted with faculty, residence hall matrons, and hotel staff. Non-commercial transactional sex is defined here as engaging in sex for the purposeof obtaining material goods, financial support, or grades.Support from the President’s Emergency Plan for AIDS Relief (PEPFAR) through the U.S. Agency for International Development under Project SEARCH Task Order No. GHH‐I‐00‐07‐00023‐00, beginning August 27, 201

Cranial biomechanics, bite force and function of the endocranial sinuses in Diprotodon optatum, the largest known marsupial

The giant extinct marsupial Diprotodon optatum has unusual skull morphology for an animal of its size, consisting of very thin bone and large cranial sinuses that occupy most of the internal cranial space. The function of these sinuses is unknown as there are no living marsupial analogues. The finite element method was applied to identify areas of high and low stress, and estimate the bite force of Diprotodon to test hypotheses on the function of the extensive cranial sinuses. Detailed three‐dimensional models of the cranium, mandible and jaw adductor muscles were produced. In addition, manipulations to the Diprotodon cranial model were performed to investigate changes in skull and sinus structure, including a model with no sinuses (sinuses ‘filled’ with bone) and a model with a midsagittal crest. Results indicate that the cranial sinuses in Diprotodon significantly lighten the skull while still providing structural support, a high bite force and low stress, indicating the cranium may have been able to withstand higher loads than those generated during feeding. Data from this study support the hypothesis that pneumatisation is driven by biomechanical loads and occurs in areas of low stress. The presence of sinuses is likely to be a byproduct of the separation of the outer surface of the skull from the braincase due to the demands of soft tissue including the brain and the large jaw adductor musculature, especially the temporalis. In very large species, such as Diprotodon, this separation is more pronounced, resulting in extensive cranial sinuses due to a relatively small brain compared with the size of the skull

Arbuscular mycorrhiza potentiates the quality of fruits but does not influence the precocity of goldenberry plants / A micorriza arbuscular potencializa a qualidade de frutos mas não influencia a precocidade de plantas de fisális

The alternative to minimize the impacts to the agroecosystem and to establish a sustainable management for the goldenberry cultivation (Physalis peruviana L.) corresponds to the use of inoculants based on arbuscular mycorrhizal fungi (AMF). However, this biotechnological tool is lacking and unknown to producers. The objective of the research was to investigate whether goldenberry plants in the absence and presence of inoculation with AMF differ in their horticultural potential. The treatments were absence of inoculation (control) and three mycorrhizal inoculants, arranged in a randomized block design, with five replications. The phyllochron, mycorrhizal colonization and fruit quality were evaluated. Non-mycorrhized plants had a higher leaf appearance rate and, therefore, a lower phyllochron value. Mycorrhizal colonization was greater in roots of plants produced with Glomus intraradices. Less acid and more tasty fruits were produced by plants inoculated with AMF, regardless of the fungal treatment used. In conclusion, goldenberry plants in the absence and presence of inoculation with AMF have different horticultural potential. Plants devoid of arbuscular mycorrhiza are earlier to start flowering. The fungal species G. intraradices is more effective in colonizing the roots of the plant host. Plants submitted to mycorrhizal biotechnology potentiate the chemical quality of berries

Changes in suspected adverse drug reaction reporting via the Yellow Card scheme in Wales following the introduction of a National Reporting Indicator

AIMS: This study aimed to assess the impact of a National Reporting Indicator (NRI) on rates of reporting of suspected adverse drug reactions using the Yellow Card scheme following the introduction of the NRI in Wales (UK) in April 2014. METHODS: Yellow Card reporting data for general practitioners and other reporting groups in Wales and England for the financial years 2014–15 (study period 1) and 2015–16 (study period 2) were obtained from the Medicines and Healthcare Products Regulatory Agency and compared with those for 2013–14 (pre‐NRI control period). RESULTS: The numbers of Yellow Cards submitted by general practitioners in Wales were 271, 665 and 870 in the control period, study period 1 and study period 2, respectively. This is equivalent to an increase of 145% in study period 1 and 221% in study period 2 compared with the 12‐month control period (2013–14). Corresponding increases in England were 17% and 37%, respectively (P < .001 chi–squared test). The numbers of Yellow Cards submitted by other groups in Wales were 906, 795 and 947 in each of the study periods. CONCLUSIONS: Introduction of the NRI corresponded with a significant increase in the number of Yellow Cards submitted by general practitioners in Wales. General practitioner reporting rates continued to increase year on year through to 2018–19 with the NRI still in place. No concomitant change was found in reporting rates by other groups in the health boards in Wales

Clinical Characteristics, Mutation Spectrum, and Prevalence of Åland Eye Disease/Incomplete Congenital Stationary Night Blindness in Denmark

PURPOSE: To assess clinical characteristics, foveal structure, mutation spectrum, and prevalence rate of Åland eye disease (AED)/incomplete congenital stationary night blindness (iCSNB). METHODS: A retrospective survey included individuals diagnosed with AED at a national low-vision center from 1980 to 2014. A subset of affected males underwent ophthalmologic examinations including psychophysical tests, full-field electroretinography, and spectral-domain optical coherence tomography. RESULTS: Over the 34-year period, 74 individuals from 35 families were diagnosed with AED. Sixty individuals from 29 families participated in a follow-up study of whom 59 harbored a CACNA1F mutation and 1 harbored a CABP4 mutation. Among the subjects with a CACNA1F mutation, subnormal visual acuity was present in all, nystagmus was present in 63%, and foveal hypoplasia was observed in 25/43 subjects. Foveal pit volume was significantly reduced as compared to normal (P < 0.0001). Additionally, outer segment length at the fovea was measured in 46 subjects and found to be significantly reduced as compared to normal (P < 0.001). Twenty-nine CACNA1F variations were detected among 34 families in the total cohort, and a novel CABP4 variation was identified in one family. The estimated mean birth prevalence rate was 1 per 22,000 live-born males. CONCLUSIONS: Our data support the viewpoint that AED, iCSNB, and X-linked cone–rod dystrophy 3 are designations that refer to a broad, continuous spectrum of clinical appearances caused in the majority by a variety of mutations in CACNA1F. We argue that the original designation AED should be used for this entity
