The current study aimed to extend existing research concerning HPV vaccination rates, sexual behaviour practices, and risk of HPV-related morbidity and mortality among Canadian university students. A survey research firm recruited an online sample of Canadian university students between 18 and 24 years of age and from across Canada for a study of student sexual health. The current report represents a secondary analysis of responses to this sexual health survey that is focused on HPV morbidity risk. An analysis sample of 1,412 university students responded to an assessment of demographic characteristics, HPV vaccination status (vaccinated or unvaccinated), and recent and lifetime sexual behaviours and condom use. Conservative estimates indicated that approximately one-quarter of university student women, at least two-thirds of university student men, and at least one-third of trans/ non-binary university students had not been vaccinated against HPV. Recent and lifetime sexual behaviours of HPV vaccinated and HPV unvaccinated university students were strikingly similar. HPV unvaccinated status, HPV-risk sexual behaviour, and HPV-related morbidity and mortality risk were very common in this national sample of Canadian university students. Cost-free catch-up HPV vaccination programs for unvaccinated university students are urgently needed to mitigate substantial HPV-related health risks in this population. KEYWORDS: HPV, HPV morbidity risk, HPV vaccine, sexual behaviour, university students, Human papillomavirus (HPV) appears to be the most common sexually transmitted infection (STI) in Canada (Marra et al., 2009; Steben & Gale-Rowe, 2014) and worldwide (Bosch et al., 2012; Bruni [...]

Insulin edema is a poorly understood complication of insulin therapy. It has been reported in patients with both type 1 and 2 diabetes mellitus and typically occurs in patients with newly diagnosed or poorly controlled diabetes mellitus either after initiation or intensification of insulin therapy. A 20-year-old man presented with anorexia, polydipsia, and weight loss. Serum glucose on admission was 824 mg/dL (45.8 mmol/L) and hemoglobin A1c was >14.0. Additional workup was notable for positive anti-IA2 antibodies and low C-peptide of 0.5 ng/mL (1.1-4.4 ng/mL). He was diagnosed with type 1 diabetes mellitus and was started on insulin therapy with glargine and lispro. Within 4 days after insulin initiation, he developed bilateral leg swelling and reported a 25-pound (11.3-kg) weight gain over the next 10 days. After excluding other systemic causes of edema such as heart failure, renal failure, and liver failure, a diagnosis of insulin edema was made. Insulin glargine was switched to insulin degludec. Complete resolution of edema occurred within 3 days of switching the insulins. Insulin edema is a diagnosis of exclusion. Insulin's role in renal sodium handling, vasodilation, and increased vascular permeability have been postulated as possible mechanisms. Clinicians should be aware of this rare complication.

Cognitive control is the ability to flexibly adapt behavior in a goal-directed manner when habit will not suffice. Control can be separated into distinct forms based on the timescale (present–future) and/or medium (external–internal) over which it operates. Both the frontoparietal network (FPN) and cingulo-opercular network (CON) are engaged during control, but their respective functions and interactions remain unclear. Here, we examined activations in the FPN and CON with fMRI in humans (male and female) during a task that manipulated control across timescales/mediums. The findings show that the CON can be distinguished into the following two separable subnetworks mirroring the FPN: a rostral/ventral subnetwork sensitive to future-oriented control involving internal representations, and a caudal/dorsal subnetwork sensitive to presentoriented control involving external representations. Relative to the FPN, activation in the CON was particularly pronounced during transitions into and out of particular control demands. Moreover, the relationship of each CON subnetwork to behavior was mediated by a respective FPN subnetwork. Such data are consistent with the idea that the CON motivates the FPN, which, in turn, drives behavior. Within the CON, the dorsomedial prefrontal cortex (dmPFC) mediated the relationship between the anterior insula and FPN, suggesting that the dmPFC acts as the crux that links the CON to the FPN. Collectively, these data indicate that parallel CON–FPN subnetworks mediate controlled behaviors at distinct timescales/ mediums. [ABSTRACT FROM AUTHOR]

Background: Healthcare technologies are becoming more commonplace, however clinical and patient perspectives regarding the use of technology in the management of childhood asthma have yet to be investigated. Within a clinical trial of asthma management in children, we conducted a qualitative process evaluation that provided insights into the experiences and perspectives of healthcare staff and families on (i) the use of smart inhalers to monitor medication adherence and (ii) the use of algorithm generated treatment recommendations. Methods: We interviewed trial staff (n = 15) and families (n = 6) who were involved in the trial to gauge perspectives around the use of smart inhalers to monitor adherence and the algorithm to guide clinical decision making. Findings: Staff and families indicated that there were technical issues associated with the smart inhalers. While staff suggested that the smart inhalers were good for monitoring adherence and enabling communication regarding medication use, parents and children indicated that smart inhaler use increased motivation to adhere to medication and provided the patient (child) with a sense of responsibility for the management of their asthma. Staff were open-minded about the use of the algorithm to guide treatment recommendations, but some were not familiar with its' use in clinical care. There were some concerns expressed regarding treatment step-down decisions generated by the algorithm, and some staff highlighted the importance of using clinical judgement. Families perceived the algorithm to be a useful technology, but indicated that they felt comforted by the clinicians' own judgements. Conclusion: The use of technology and individual data within appointments was considered useful to both staff and families: closer monitoring and the educational impacts were especially highlighted. Utilising an algorithm was broadly acceptable, with caveats around clinicians using the recommendations as a guide only and wariness around extreme step-ups/downs considering contextual factors not taken into account.

BACKGROUND: Sensory processing dysfunction in children has been linked to attention-deficit/hyperactivity disorder, autism, feeding disorders, and functional abdominal pain. However, little is known about sensory processing in the broader pediatric gastroenterology population. OBJECTIVE: To characterize frequency and type of sensory processing dysfunction seen in pediatric gastroenterology compared to a general pediatric population. METHODS: The Short Sensory Profile 2 was administered to the parents of children ranging 3-14 years, being seen in a pediatric gastrointestinal (Gl) subspecialty clinic or general pediatric clinic. Short Sensory Profile 2 scores from age- and gender-matched groups were compared with nonparametric statistics. RESULTS: Sensory processing dysfunction was increased in children seen in the Gl clinic compared to children in the general pediatric clinic. Short Sensory Profile 2 quadrant analysis revealed greatest differences in avoiding, primarily in young females of the Gl population. CONCLUSION: Children presenting to a pediatric Gl clinic demonstrate greater sensory processing dysfunction compared to children in a general pediatric practice. [ABSTRACT FROM AUTHOR]

The truncate soft-shell clam Mya truncata is an important source of country food for Inuit communities across the territory of Nunavut, Canada. M. truncata also plays an important role in marine ecosystems, yet there is little understanding of their life history and condition in Canadian Arctic waters. To provide a foundation on which aspects of the life history and condition of M. truncata of Baffin Island can be monitored in the future with a changing climate and fishery development, this study estimated size at maturity and provides insights into the spawning cycle and weight-length condition indices of clams from inner Frobisher Bay and the north shore of the Hudson Strait. Male and female M. truncata exhibited similar lengths at 50% attainment of sexual maturity, 31 mm and 32 mm shell length (SL), respectively. Most (77%) of the sexually mature M. truncata collected from inner Frobisher Bay in late August and 35% of clams collected from the Hudson Strait in early September were in the ripe stage of gonadal development. These results lead us to suggest a spring spawning season and that M. truncata invest in gonadal development for the next year's spawning during the late summer-early autumn ice-free season while phytoplankton concentrations are high. Dry bodyweight-SL relationships were used to show that M. truncata condition can differ significantly over small and large spatial scales based on plotted 95% confidence intervals.

Fixed-income corporate bond markets were the last bastion of non-electronic trading activity. For most of the twentieth century these markets were also dominated by the largest Wall Street dealer-banks. These banks had long argued that corporate bonds were too complex and illiquid to be electronified. In reality though, opaque Over-The-Counter trading in these bonds allowed Wall Street to monopolise highly uncompetitive markets; this market environment had changed very little over the decades, despite the financial services revolutions that had gripped other markets. By the 2010s however, Wall Street banks had finally begun to lose their stranglehold. This paper tracks the two explanatory factors, the emergence of new financial technology and the decisive intervention of state managers and post-crisis regulation – in the form of the Volcker Rule and Basel III. Recent accounts have become increasingly sceptical of the disruptive, pro-competitive impact of fintech. We argue that – at least in markets for US corporate bonds – there is evidence of a more competitive, democratic market environment emerging as a direct result of new financial technologies.

Background: Participants want to receive the results of trials that they have participated in. Dissemination practices are disparate, and there is limited guidance available on what information to provide to participants and how to deliver it. Objectives: This study aimed to establish what trial participants believe should be included in a results summary and how this information should be delivered. Methods: A mixed‐methods design was used with focus groups and interviews involving women convenience‐sampled from two host randomized‐controlled trials. Participants ranked information items in order of their importance for inclusion in a trial results summary and potential modes of delivery by preference. All participants provided written informed consent. Results: Sixteen women (mean age [SD] = 71.6 [9.7] years) participated. Participants ranked 'individual results from the study' and 'summary of overall trial results' as most important. Themes such as reassurance and setting results in context were identified as contributing to participants' decisions around ranking. 'A thank you for your contribution to the study' was ranked the least important. Delivery by post was the preferred mode of receiving results, with receiving a hard copy of results cited as helpful to refer back to. Conclusion: Our findings provide insight into what information trial participants deem as important when receiving trial results and how they would like results delivered. Involving patients during development of trial results to be communicated to participants could help to ensure that the right information is delivered in the right way. Patient or Public Contribution: Public partners were involved in focussed aspects of study conduct. [ABSTRACT FROM AUTHOR]

Background: Memory decline in late life is a hallmark of aging, yet SuperAgers are individuals age 80 or older with episodic memory performance at least as good as cognitively average 50‐to‐60‐year‐olds. Neuroimaging analyses have found SuperAgers to have thicker cortices and slower atrophy rates compared to similarly aged controls (Controls). This project extended the anatomical findings by examining the functional integrity of seven intrinsic networks spanning the entire cortex and two memory‐specific systems identified from task‐based and resting state studies. Methods: Within‐network functional connectivity (FC) of seven large‐scale networks and two memory systems were compared between 25 SuperAgers and 16 Controls using resting state functional MRI (rs‐fMRI) and T1‐weighted structural imaging from a single visit. Classification of SuperAgers/Controls was determined based on measures of episodic memory, executive functioning, verbal fluency, and picture naming (Harrison et al., 2012). Inclusion criteria required stable cognitive status across two visits. In the first analysis, we included all seven networks from a common resting‐state atlas (Schaefer et al., 2018). Within‐network FCs for all networks were defined as the average FCs between all within‐network regions (Figure 1A). In the second analysis, we investigated two memory‐specific networks: the anterior temporal (AT) and posterior medial (PM) systems. AT and PM cortical maps (Figure 1B) were identified from prior research (de Flores et al., 2022). Within‐network FC of the AT and PM systems were defined as the FC between AT‐to‐anterior‐hippocampus and PM‐to‐posterior‐hippocampus, respectively. For both analyses, FCs were compared across groups using two‐sample independent t‐tests and corrected for multiple comparisons (Benjamini‐Hochberg false discovery rate). Results: We found no significant between‐group differences in demographic characteristics including age, sex, and education. Performance on neuropsychological measures was significantly different for episodic memory, verbal fluency, and picture naming. Group differences in within‐network FCs for large‐scale networks and memory systems were nonsignificant. Conclusion: At the group‐level, within‐network FC of large‐scale networks and memory‐specific systems were not a primary differentiator between cognitively average aging and SuperAging phenotypes. Person‐specific functional connectome approaches may be important for understanding network organizational features of SuperAgers. [ABSTRACT FROM AUTHOR]

This review aims to develop an evidence-based pathway for isolated adult orbital blowout fractures. Evaluation of assessment methods, outcome measures, imaging modalities, and crucially, the optimal timing of surgical intervention was critically examined to develop a clinically applicable care pathway. A literature search was carried out using Scopus, PubMed and Web of Knowledge. The literature favors the use of HAR% ratio, Field of Binocular Single Vision (FOBSV) and Exophthalmometer as the core tests that should form part of the standardized assessment for blow-out fractures (BOFs). CT imaging remains gold standard, particularly to identify 'red-flags' warranting early intervention. There was some disagreement in relation to timing of intervention in adult fractures who continue to be symptomatic without initial extraocular muscle (EOM) entrapment and enophthalmos >3 mm, where early intervention within two weeks is not indicated. The limited literature available agreed that successful functional and radiological outcomes can be achieved with conservative or late surgical management following an extended observational period of four weeks, opposed to the conventional two weeks. An evidence-based care pathway has been created, confidently including the initial assessment methods, imaging modality, and the criteria for observation. A four-week observational period has been advocated due to evidence suggesting that there is no significant difference in outcomes from two-week observation, plus with careful functional evaluation, surgery may be avoided in some cases.

Working memory (WM) is the ability to maintain and manipulate internal representations. WM recruits varying brain regions based on task demands. Although the hippocampus has historically been associated with long-term memory (LTM), several studies provide evidence for its involvement during WM tasks. Slotnick (this issue) posits that this involvement is due to LTM processes. This argument rests on the assumption that processes are not shared among WM and LTM, and that WM processes are necessarily sustained. We argue that there are processes utilized by both WM and LTM, and that such processes need not be sustained to support WM. [ABSTRACT FROM AUTHOR]

While traditional economic models assume that agents are self-interested, humans and most non-human primates are social species. Therefore, many of decisions they make require the integration of information about other social agents. This study asks to what extent information about social status and the social context in which decisions are taken impact on reward-guided decisions in rhesus macaques. We tested 12 monkeys of varying dominance status in several experimental versions of a two-choice task in which reward could be delivered to self only, only another monkey, both the self and another monkey, or neither. Results showed dominant animals were more prone to make prosocial choices than subordinates, but only when the decision was between a reward for self only and a reward for both self and other. If the choice was between a reward for self only and a reward for other only, no animal expressed altruistic behaviour. Finally, prosocial choices were true social decisions as they were strikingly reduced when the social partner was replaced by a non-social object. These results showed that as in humans, rhesus macaques' social decisions are adaptive and modulated by social status and the cost associated with being prosocial. [ABSTRACT FROM AUTHOR]
