RESUMEN
This case report describes a patient in whom debilitating lower back pain that always occurred during menses resolved when she received treatment for subclinical temporomandibular disorder (TMD). The patient was diagnosed with subclinical TMD and facial myalgia based on the results of clinical and radiographic examinations. She was treated with maxillary (nighttime) and mandibular (daytime) dental orthotics to provide stabilization and decompression of the temporomandibular joints. After 12 weeks of appliance therapy, which resulted in resolution of the TMD symptoms, the patient reported that the debilitating lower back pain she experienced during menses had ceased. Her back pain did not return after the use of the mandibular appliance was discontinued. The authors discuss how neurologic, postural, inflammatory, and qi flow changes attributed to the patient's TMD treatment may have contributed to the cessation of the patient's menses-related lower back pain.

The last two decades have seen dramatic growth in the application of procedurally based interventions for treating refractory psychiatric conditions, leading to interest in developing the foundations for the subspecialty of "Interventional Psychiatry." However, there is cause for concern that the rate of expansion of clinical advances in this field may be outpacing the ability of postgraduate curricula to provide sufficient exposure to and teaching and supervision of these treatments. The paucity of adequately trained practitioners in Interventional Psychiatry further exacerbates inequities in the ability of eligible patients to access and benefit from these approaches. This paper explores the rates of utilization of Interventional Psychiatry treatments, the current state of education in these treatments, and the role that training can play in translating scientific advances in this area to ensure equitable access and maximum impact at a population level. The majority of the discussion is centered on electroconvulsive therapy (ECT), the most established and available of these treatments, highlighting how enhancing education and training in ECT can reduce barriers to its utilization. It is argued that innovations in pedagogical approaches for disseminating the learning of these procedures are needed to increase the current low rates of competency in these treatments and can facilitate the more rapid dissemination of other Interventional Psychiatry approaches and neurotechnologies, such as repetitive transcranial magnetic stimulation, ketamine, deep brain stimulation, and focused ultrasound.

This case report describes a patient with a primary concern of persistent mandibular deviation during speech who experienced clinically significant improvement (mandibular movement without deviation) after improvements to nasal resistance. At the initial consultation, temporary placement of a nasal valve dilator immediately eliminated the patient's mandibular deviation during speech, indicating the need for referral to an otolaryngologist. The patient was also provided with a dental appliance to address secondary concerns of temporomandibular joint noises and cervicofacial pain. Although the dental treatment provided some relief, resolution of the patient's mandibular deviation during speech did not occur until after nasal surgery was completed. This case illustrates the importance and effects of nasal resistance and nasal patency to obtaining a reproducible mandibular position.

OBJECTIVES: Social media platforms are increasingly being used to disseminate mental health information online. User-generated content about attention-deficit/hyperactivity disorder (ADHD) is one of the most popular health topics on the video-sharing social media platform TikTok. We sought to investigate the quality of TikTok videos about ADHD. METHOD: The top 100 most popular videos about ADHD uploaded by TikTok video creators were classified as misleading, useful, or personal experience. Descriptive and quantitative characteristics of the videos were obtained. The Patient Education Materials Assessment Tool for Audiovisual Materials (PEMAT-A/V) and Journal of American Medical Association (JAMA) benchmark criteria were used to assess the overall quality, understandability, and actionability of the videos. RESULTS: Of the 100 videos meeting inclusion criteria, 52% (n = 52) were classified as misleading, 27% (n = 27) as personal experience, and 21% (n = 21) as useful. Classification agreement between clinician ratings was 86% (kappa statistic of 0.7766). Videos on the platform were highly understandable by viewers but had low actionability. Non-healthcare providers uploaded the majority of misleading videos. Healthcare providers uploaded higher quality and more useful videos, compared to non-healthcare providers. CONCLUSIONS: Approximately half of the analyzed TikTok videos about ADHD were misleading. Clinicians should be aware of the widespread dissemination of health misinformation on social media platforms and its potential impact on clinical care.

OBJECTIVE: The current study aims to assess the self-reported competence of graduating psychiatry residents in Canada to provide pharmacotherapy and psychotherapy for major depressive disorder as recommended in national practice guidelines. METHODS: Canadian psychiatry residents who participated in an optional national review course to prepare for licensing were anonymously surveyed regarding their experience and competence in providing treatments recommended by the 2016 Canadian Network for Mood and Anxiety Treatments guidelines. RESULTS: The majority (89%, 130/146) reported competence in ≥ 5 medication monotherapies (e.g., selective serotonin/norepinephrine reuptake inhibitors, bupropion, mirtazapine) and ≥ 3 adjuncts (e.g., mirtazapine, second-generation antipsychotics). While 76% expressed interest in practicing multiple psychotherapeutic modalities, only 47% reported self-assessed competence in delivering multiple modalities. Only 42% reported pharmacological competence (≥ 5 monotherapies, ≥ 3 adjuncts) and competence in ≥ 2 psychotherapies. Only 9% reported competence in offering medication, psychotherapy, and electroconvulsive therapy. Less than two-thirds endorsed sufficient didactic teaching (58%) or supervision in pharmacotherapy (50%) for treatment-resistant depression. CONCLUSIONS: Canadian psychiatry residents report competence in prescribing many first-line medications. However, only a minority report competence in prescribing medications and competence in psychotherapies and/or electroconvulsive therapy. Given known biases in assessments by self-report, real-world competence may be even lower. This study identifies gaps between national practice guidelines and the comfort of the emerging psychiatric workforce in delivering recommended treatments. These gaps in resident competence may lead to under-use of effective treatments for depression. Residency programs should consider how to improve resident competence in providing the full range of evidence-based treatments for depression.

Student-run free clinics are increasingly seen as a way for students in health professions to have early authentic exposures to providing care to marginalized populations, often in the context of interprofessional teams. However, few studies characterize what and how students may learn from volunteering at a student-run free clinic. We aimed to examine shifts in attitude or practice that volunteers report after completing a placement at an interprofessional student-run clinic in Toronto, Ontario, Canada. Transcripts from semi-structured reflective focus groups were analyzed in an exploratory thematic manner and from the perspective of transformative learning theory. Volunteers reported attitude shifts toward greater self-awareness of assumptions, recognition of the need for systemic interventions, and seeing themselves as learning and contributing meaningfully in a team even without direct-client contact. Practice shifts emerged of individualizing assessment and treatment of patients as well as increased comfort working in interprofessional teams. Attitude and practice shifts were facilitated by authentic interactions with individuals from marginalized populations, taking a patient-centered approach, and an interprofessional context. Interprofessional student-run free clinics are suited to triggering disorienting dilemmas that set the stage for transformative learning, particularly when volunteers are guided to reflect.

PURPOSE: Given limited data available on long-term outcomes in 22q11.2 deletion syndrome (22q11.2DS), we investigated mortality risk in adults with this microdeletion syndrome. METHODS: We studied 309 well-characterized adults (age ≥17 years) with 22q11.2DS and their 1014 unaffected parents and siblings, using a prospective case-control design. We used Cox proportional hazards regression modeling and Kaplan-Meier curves to investigate effects of the 22q11.2 deletion and its associated features on all-cause mortality and survival. RESULTS: The 22q11.2 deletion (hazard ratio [HR] 8.86, 95% CI 2.87-27.37) and major congenital heart disease (CHD; HR 5.03, 95% CI 2.27-11.17), but not intellectual disability or psychotic illness, were significant independent predictors of mortality for adults with 22q11.2DS compared with their siblings. Amongst those with 22q11.2DS, there were 31 deaths that occurred at a median age of 46.4 (range 18.1-68.6) years; a substantial minority had outlived both parents. Probability of survival to age 45 years was approximately 72% for those with major CHD, and 95% for those with no major CHD (p < 0.0001). CONCLUSION: For adults with 22q11.2DS, the 22q11.2 deletion and more severe forms of CHD both contribute to a lower life expectancy than family-based expectations. The results have implications for genetic counseling and anticipatory care.

Depression and substance use disorders are often comorbid, but the reasons for this are unclear. In human studies, it is difficult to determine how one disorder may affect predisposition to the other and what the underlying mechanisms might be. Instead, animal studies allow experimental induction of behaviors relevant to depression and drug-taking, and permit direct interrogation of changes to neural circuits and molecular pathways. While this field is still new, here we review animal studies that investigate whether depression-like states increase vulnerability to drug-taking behaviors. Since chronic psychosocial stress can precipitate or predispose to depression in humans, we review studies that use psychosocial stressors to produce depression-like phenotypes in animals. Specifically, we describe how postweaning isolation stress, repeated social defeat stress, and chronic mild (or unpredictable) stress affect behaviors relevant to substance abuse, especially operant self-administration. Potential brain changes mediating these effects are also discussed where available, with an emphasis on mesocorticolimbic dopamine circuits. Postweaning isolation stress and repeated social defeat generally increase acquisition or maintenance of drug self-administration, and alter dopamine sensitivity in various brain regions. However, the effects of chronic mild stress on drug-taking have been much less studied. Future studies should consider standardizing stress-induction protocols, including female subjects, and using multi-hit models (e.g. genetic vulnerabilities and environmental stress).

Student-run free clinics (SRFCs) have existed in Canada since 1971, providing interprofessional healthcare to underserved populations. SRFCs are seen as vehicles for socially accountable health professional education. Literature on how Canadian SRFC function is lacking. Web-based surveys were sent to student leaders from Canadian SRFCs regarding their 2014 activities. All six fully-functioning SRFCs responded reporting on the following: services provided, professions involved, governing structure, funding sources, clients seen, types of care sought, students and preceptors involved, as well as perceived strengths, weaknesses, opportunities and threats. In 2014, 2,159 clients were provided clinical care at Canadian SRFCs. The most common reasons for visiting included pain and infection. Strengths identified include autonomy, ability to adapt to client needs, serving the underserved, and real-world interprofessional teamwork. Weaknesses reported include high student and preceptor turnover. Threats include securing funding and liability coverage. Since there is little literature on Canadian SRFCs, we compared our results with United States (US) based SRFCs. Canadian SRFCs share core values with US-based SRFCs and report similar strengths and challenges. However, Canadian SRFCs differ in scope and appear to provide care for more acute concerns. Data from studies of US-based SRFCs may not be immediately applicable to Canadian SRFCs. Studies evaluating Canadian SRFCs are needed.

PURPOSE: There has been limited examination of clinician scientist training in Canada, particularly regarding training integration and funding. This study assessed program structure, funding, tuition and mentorship structures available at Canadian MD/PhD programs. METHODS: Clinician Investigator Trainee Association of Canada administered an anonymous survey to current trainees and program directors that captured program structure, trainee funding, tuition and mentorship opportunities and needs across institutions. RESULTS: In June 2015, 101/228 (44%) trainees and 9/13 (69%) program directors completed the online survey. In all programs, students completed the PhD degree prior to clerkship training. Seven programs offered research training upon completion of pre-clerkship, four offered concurrent clinical and research training, and three offered alternative structures. Nine held seminars exposing students to clinical and research integration and two offered clinician scientist skills courses. Stipend funding and tuition varied, especially during clinical training years. Regarding mentorship, all programs held regular meetings, though eight programs do not have formal mentorship opportunities. Both trainees and program directors identified the need for further career planning and development support as a student priority. CONCLUSION: MD/PhD programs varied by program structure, funding, tuition and mentorship opportunities. Mechanisms to share and spread program innovations should be instated. Students may benefit from concurrent research and clinical training as well as courses specific to clinician scientist skill development. Decreasing debt burden may attract and retain trainees in this demanding path. To ensure mentorship programs align with trainee priorities, program directors should directly collaborate with students in their development and evaluation.

PURPOSE: The Clinician Investigator Trainee Association of Canada/ Association des cliniciens-chercheurs en formation du Canada (CITAC/ACCFC) recently published the first survey to assess factors contributing to trainee satisfaction. One key finding is that increased level of mentorship strongly correlates with overall satisfaction; however, while 98% of respondents reported mentorship as important to success, more than 60% expressed some dissatisfaction with the mentorship received. To help address this discrepancy, we reviewed mentorship in academic medicine, focusing on clinician-investigator trainees, and distilled a set of recommendations for mentors, mentees and institutions. SOURCE: OVID and manual curation based on the search terms 'mentorship' AND 'education, medical and research' identified 198 articles. Two authours independently reviewed both titles and abstracts and narrowed them down to 75 articles, based on relevance to mentorship in academic medicine. Consensus resulted in the selection of 19 articles for detailed review. Principal findings and Conclusion: Mentorship is beneficial at each training stage and is associated with greater research productivity, career retention and promotion. Nevertheless, more rigorous studies are needed, especially regarding cost-effectiveness. Studies have identified the characteristics of good mentors, including the ability to ensure open communication, ability to maintain confidentiality and ability to ensure that there is no mentor-mentee competition. Similarly, the characteristics of good mentees have been identified as the ability to take ownership of a project and the ability to build a network or team of mentors. The literature has also identified the actions that institutions can take to facilitate mentorship, which include mentor training and recognizing mentorship through awards.

BACKGROUND: Patient expectations, including both positive (placebo) and negative (nocebo) effects, influence treatment outcomes, yet their impact on acute repetitive transcranial magnetic stimulation (rTMS) for treatment-resistant depression (TRD) is unclear. METHODS: In this single-center retrospective chart review, 208 TRD patients completed the Stanford Expectation of Treatment Scale (SETS) before starting open-label rTMS treatment. Patients were offered two excitatory rTMS protocols (deep TMS or intermittent theta-burst stimulation), which stimulated the left dorsolateral prefrontal cortex. A minimum of 20 once daily treatments were provided, delivered over 4-6 weeks. Primary outcomes were 1) remission, measured by a post-treatment score of <8 on the Hamilton Depression Rating Scale (HAMD-17), and 2) premature discontinuation. The change in HAMD-17 scores over time was used as a secondary outcome. Physicians were blinded to SETS scores. Logistic and linear regression, adjusting for covariates, assessed SETS and HAMD-17 relationships. RESULTS: Of 208 patients, 177 had baseline and covariate data available. The mean positivity bias score (positive expectancy minus negative expectancy subscale averages) was 0.48 ± 2.21, indicating the cohort was neutral regarding the expectations of their treatment on average. Higher positive expectancy scores were significantly associated with greater odds of remission (OR = 1.90, p = 0.003) and greater reduction in HAMD-17 scores (ß = 1.30, p = 0.005) at the end of acute treatment, after adjusting for covariates. Negative expectancy was not associated with decreased odds of remission (p = 0.2) or treatment discontinuation (p = 0.8). CONCLUSIONS: Higher pre-treatment positive expectations were associated with greater remission rates with open-label rTMS in a naturalistic cohort of patients with TRD.
RESUMEN
PURPOSE: Clinician Investigator Trainee Association of Canada/ Association des cliniciens-chercheurs en formation du Canada (CITAC/ACCFC) represents the interests of clinician-investigator (CI) trainees across Canada. To better advocate for the successful training of CI trainees in Canada, CITAC/ACCFC conducted a survey to assess satisfaction with their training and to find what factors were most associated with satisfaction level. METHODS: A nominal scale-based psychometric survey was conducted online in 2009 on CI trainees in Canada (including MD/MSc, MD/PhD, or CIP/SSP). One hundred fifteen out of a target population of approximately 350-400 responded. Survey respondents were asked to rate their level of satisfaction in four areas: 1) quality of training, 2) financial support, 3) mentorship satisfaction and 4) program structure. Ratings in these four areas were also combined to produce a measure of overall satisfaction. RESULTS: At least half of the respondents were 'completely satisfied' in each of the four categories other than mentorship. While 98% of respondents considered mentorship as important to their success, 62% expressed some level of dissatisfaction with the level of mentorship received. Moreover, increased levels of mentorship were strongly associated with increased levels of overall satisfaction. CONCLUSION: The discrepancy between CI trainees' perceived importance of mentorship and the level of satisfaction in mentorship received reveals a strategic area where CI training should be improved. Recognizing that good mentorship in a CI training program often begins with one's research supervisor, the CITAC/ACCFC has compiled six specific recommendations for finding a good supervisor.

Purpose: To demonstrate the effect of an orofacial myofunctional therapy intervention by an interdisciplinary team composed of a registered dental hygienist who is also a certified orofacial myologist (COM®), a general dentist, and an orthodontist on the elimination of oral habits and changes in dental malocclusion. Method: This case study describes a 7-year-old female who underwent an individualized myofunctional therapy program and was given supervised education on a series of exercises targeting the muscles of mastication and facial expression over 5 months. Correct oral rest postures of the tongue and the lips were also established through therapy. Results: The intervention enabled the client to eliminate multiple oral habits, which corrected oral rest postures of the lips and tongue. This correction consequently improved the client's malocclusion and further prepared the client for future orthodontic treatment. Conclusion: Myofunctional therapy facilitated the elimination of unfavourable oral habits that led to malocclusion. Eliminating oral habits better prepared the client for orthodontic treatment and retention. Use of an interdisciplinary team facilitates optimal client care.
Objectif: Démontrer l'effet d'une thérapie orofaciale myofonctionnelle par une équipe interdisciplinaire composée d'un hygiéniste dentaire autorisé qui est aussi un myologiste orofacial certifié (COM®), d'un dentiste généraliste et d'un orthodontiste sur l'élimination des habitudes buccales et les changements de la malocclusion dentaire. Méthodologie: La présente étude de cas décrit une fille de 7 ans qui a suivi un programme personnalisé de thérapie myofonctionnelle et a reçu une éducation supervisée sur une série d'exercices ciblant les muscles de la mastication et de l'expression faciale au cours d'une période de 5 mois. La thérapie a aussi permis d'établir des postures appropriées de repos de la langue et des lèvres. Résultats: Grâce à la thérapie, la cliente a pu éliminer de multiples habitudes buccales, ce qui a corrigé les postures de repos buccal des lèvres et de la langue. Cette modification a par conséquent amélioré la malocclusion de la cliente et a permis de la préparer à un futur traitement orthodontique. Conclusion: La thérapie myofonctionnelle a favorisé l'élimination d'habitudes buccales défavorables qui ont mené à la malocclusion. En éliminant les habitudes buccales, la cliente était mieux préparée au traitement orthodontique et à la rétention. L'utilisation d'une équipe interdisciplinaire optimise les soins du client.

BACKGROUND: History of adverse childhood experiences (ACEs) is associated with poorer treatment outcomes in depression. How ACEs affect outcomes from repetitive transcranial magnetic stimulation (rTMS) is not well-defined. The primary aim was to investigate whether ACEs affect depression outcomes in patients receiving high frequency rTMS, either deep TMS (dTMS) or intermittent theta burst stimulation (iTBS), to the left dorsolateral prefrontal cortex. METHODS: The Hamilton Depression Rating Scale (HAMD-17) was collected at baseline and every 2 weeks for 4-6 weeks. Outcomes included improvement in HAMD-17 and remission. The ACE-10 questionnaire was used to quantify categories of ACEs. Data from 99 patients with MDD receiving an acute rTMS course were analyzed. RESULTS: Patients had a mean of 2.4 ACEs (SD 2.5). No significant differences in outcomes were found between dTMS or iTBS so these data were pooled. Using a continuous ACE variable showed no significant impact on outcomes. Using a categorical ACE variable (0, 1, 2, 3, 4 or more) did not reveal significant effects of ACEs on outcomes. Higher ACE was associated with steeper decrease in HAMD-17 only from baseline to week 2 but not at other times. LIMITATIONS: This was an open-label study. The well-validated ACE questionnaire does not measure severity or frequency of adversities. CONCLUSIONS: Patients with depression receiving rTMS reported on average 2.4 ACEs. ACE scores may lead to a steeper early decline in HAMD-17 but did not otherwise impact depression outcomes. Presence of high levels of ACEs should not preclude consideration of rTMS for depression.

Individuals with major depressive disorder (MDD) may exhibit a seasonal pattern. The impact of a seasonal pattern in depressive symptoms on rTMS outcomes is unexplored. A retrospective analysis was performed on patients with MDD receiving open-label high frequency rTMS to the left dorsolateral prefrontal cortex. Having a seasonal pattern was defined as scoring ≥ 12 on the Personal Inventory for Depression and Seasonal Affective Disorder (PIDS). Primary outcomes included improvement in the Hamilton Depression Rating Scale (HAMD) and remission. Secondary analyses included the use of the self-rated Quick Inventory of Depressive Symptomatology (QIDS) to assess for changes in atypical neurovegetative symptoms. Multiple linear regression, multiple logistic regression, and linear mixed effects analyses were performed. 46 % (58/127) of the sample had a seasonal pattern. Seasonal pattern did not significantly influence improvement in HAMD (PIDS < 12, 7.8, SD 5.9; PIDS ≥ 12, 10.4, SD 4.9 or remission (PIDS < 12, 30 %; PIDS ≥ 12, 34 %). There were equivalent degrees of improvement in atypical neurovegetative symptoms over time as assessed using the QIDS. Depression with seasonal pattern was found to respond to rTMS treatment similarly to depression without seasonal pattern, suggesting that this may be a viable treatment for this group.

BACKGROUND: During the COVID-19 pandemic, educational interventions have become necessary to prevent the spread of health-related misinformation among Hong Kong older adults. The primary objective of this study was to assess the feasibility of a student-led, telephone-delivered intervention to improve COVID-19-related health knowledge among Hong Kong older adults. The secondary objective was to evaluate the impact of the intervention on the student volunteers. METHODS: Twenty-five participants aged 65 or above who were able to communicate in Cantonese and had no hearing or cognitive impairments were recruited for this longitudinal pre-post-study from a community center in Hong Kong. The pilot telephone-delivered intervention consisted of five telephone call sessions conducted by 25 student volunteers. Each participant was paired with the same volunteer throughout the intervention. The first four sessions included pre-tests that assessed the participants' understanding of three COVID-19-related themes: medication safety, healthcare voucher scheme, and COVID-19 myth-busting. Standardized explanations of the pre-test questions were offered to participants during the phone calls. In the last session, a post-test on all the themes was conducted. The intervention's feasibility was assessed based on (a) percentage changes in the participants' test scores, (b) attrition rate, and (c) the acceptability of the intervention by the participants. The impact of the intervention on the student volunteers was evaluated based on a student feedback survey. There was no control group. RESULTS: Significant improvements in the participants' test scores (out of 100%) for all themes were observed after the intervention: from 76 to 95.2% for medication safety, from 64.0 to 88.8% for the healthcare voucher scheme, and from 78.0 to 93.2% for COVID-19 myth-busting. The average improvement in test scores of the three themes was 18.4% (95% CI 12.2 to 24.6%). Most participants were satisfied with the program. The student feedback survey suggested that the intervention enhanced students' communication skills and understanding of Hong Kong older adults. CONCLUSION: This pilot study offers initial evidence of the potential and feasibility of student-led, telephone-delivered educational interventions for the transfer of COVID-19-related knowledge to older adults and their benefits for the student volunteers. Future studies should include larger samples and a control group.
RESUMEN
High quality, well-validated antibodies are needed to mitigate irreproducibility and clarify conflicting data in science. We describe an epitope-directed monoclonal antibody (mAb) production method that addresses issues of antibody quality, validation and utility. The workflow is illustrated by generating mAbs against multiple in silico-predicted epitopes on human ankyrin repeat domain 1 (hANKRD1) in a single hybridoma production cycle. Antigenic peptides (13-24 residues long) presented as three-copy inserts on the surface exposed loop of a thioredoxin carrier produced high affinity mAbs that are reactive to native and denatured hANKRD1. ELISA assay miniaturization afforded by novel DEXT microplates allowed rapid hybridoma screening with concomitant epitope identification. Antibodies against spatially distant sites on hANKRD1 facilitated validation schemes applicable to two-site ELISA, western blotting and immunocytochemistry. The use of short antigenic peptides of known sequence facilitated direct epitope mapping crucial for antibody characterization. This robust method motivates its ready adoption for other protein targets.
