Peer support in adolescents and young adults with chronic or rare conditions in northern America and Europe: Targeted literature review.

PROBLEM: Adolescents and young adults with chronic or rare conditions face unique risks to their physical, social and emotional development. Research suggests that peer support improves their quality of life and reduces social isolation. However, there is a paucity of current information considering multiple intervention formats. ELIGIBILITY CRITERIA: A targeted literature review was conducted to identify peer support interventions and assess their feasibility, acceptability and efficacy for this population. Searches were conducted in MEDLINE, Embase and American Psychological Association PsycINFO for records reporting peer support interventions in young adults with chronic or rare conditions. Data were extracted from relevant publications and qualitatively evaluated. SAMPLE: Thirty studies were included, which assessed the use of peer support for young adults (aged 13-30 years) with chronic or rare conditions in Europe or North America. RESULTS: Peer support interventions had positive effects on social positivity, psychosocial development and medical outcomes, though significance was not always demonstrated. CONCLUSIONS: Peer support can enhance care for young adults with chronic or rare conditions. Current literature suggests that once-weekly virtual interventions are the most feasible and acceptable for patients, leading to multifaceted improvements in their well-being. IMPLICATIONS: This study is one of the first to discuss in-person, virtual and hybrid peer-based interventions for young adults with chronic and rare conditions. While all formats improved social, psychological and medical outcomes, virtual formats may be most accessible to participants. Interventions should be made available to this population, and guidelines for optimal implementation of peer support are needed.

Microplastics-biofilm in aquatic ecosystem: Formation, pollutants complexation, greenhouse gas emission and ecotoxicology.

The omnipresent microplastics (MPs) have gradually become a significant environmental problem due to its adverse consequences for ecological systems. MPs serve as substrates for biofilms colonization, which enhances adsorption of harmful contaminants on MPs surface in the aquatic ecosystem. The present study provides a critical discussion on the mechanism involved in MPs-biofilm formation, microbial colonization and the robust factors influencing the process in the aquatic ecosystem. Subsequently, the impact of MPs-biofilm on adsorption of inorganic and organic contaminants is explored. The ecological significance of MPs-biofilm associated pollutant complex for promoting greenhouse gases (GHGs) emissions from aquatic ecosystem is extensively discussed for understanding the climatic risk. Furthermore, the discussion is extended over ecotoxicological impact of MPs-biofilm on aquatic biodiversity and humans. The protective extracellular polymeric substances secreted by colonised bacteria over MPs during biofilm formation creates sticky MPs surface for heteroaggregates formation with swift adsorption of chemical compounds and microorganisms. MPs with functional aromatic groups facilitate the bacterial adhesion on the surface, but affect formation of biofilm. Alternatively, MPs-biofilm promotes the Mn and Fe hydrous oxides formation that can co-precipitate with heavy metal ions and facilitate in remediation measures. However, MPs biodegradation generates GHGs emission per unit mass, comparably more from freshwater than marine ecosystem. Considering the toxicity, MPs-biofilm induces the oxidative response in fishes, causing painful death and thus, destroys aquatic biodiversity. This study will be useful to address MPs-biofilm associated pollution scenario via trace, test and treat strategy involving future engineering research framework for ecological restoration.

Safety of intracranial electroencephalography during functional electromagnetic resonance imaging in humans at 1.5 tesla using a head transmit RF coil: Histopathological and heat-shock immunohistochemistry observations.

OBJECTIVES: Simultaneous intracranial EEG and functional MRI (icEEG-fMRI) recordings in humans, whereby EEG is recorded from electrodes implanted inside the cranium during fMRI scanning, were made possible following safety studies on test phantoms and our specification of a rigorous data acquisition protocol. In parallel with this work, other investigations in our laboratory revealed the damage caused by the EEG electrode implantation procedure at the cellular level. The purpose of this report is to further explore the safety of performing MRI, including simultaneous icEEG-fMRI data acquisitions, in the presence of implanted intra-cranial EEG electrodes, by presenting some histopathological and heat-shock immunopositive labeling observations in surgical tissue samples from patients who underwent the scanning procedure. METHODS: We performed histopathology and heat shock protein expression analyses on surgical tissue samples from nine patients who had been implanted with icEEG electrodes. Three patients underwent icEEG-fMRI and structural MRI (sMRI); three underwent sMRI only, all at similar time points after icEEG implantation; and three who did not undergo functional or sMRI with icEEG electrodes. RESULTS: The histopathological findings from the three patients who underwent icEEG-fMRI were similar to those who did not, in that they showed no evidence of additional damage in the vicinity of the electrodes, compared to cases who had no MRI with implanted icEEG electrodes. This finding was similar to our observations in patients who only underwent sMRI with implanted icEEG electrodes. CONCLUSION: This work provides unique evidence on the safety of functional MRI in the presence of implanted EEG electrodes. In the cases studied, icEEG-fMRI performed in accordance with our protocol based on low-SAR (≤0.1 W/kg) sequences at 1.5T using a head-transmit RF coil, did not result in measurable additional damage to the brain tissue in the vicinity of implanted electrodes. Furthermore, while one cannot generalize the results of this study beyond the specific electrode implantation and scanning conditions described herein, we submit that our approach is a useful framework for the post-hoc safety assessment of MR scanning with brain implants.

BOLD mapping of human epileptic spikes recorded during simultaneous intracranial EEG-fMRI: The impact of automated spike classification.

OBJECTIVES: Simultaneous intracranial EEG and functional MRI (icEEG-fMRI) can be used to map the haemodynamic (BOLD) changes associated with the generation of IEDs. Unlike scalp EEG-fMRI, in most patients who undergo icEEG-fMRI, IEDs recorded intracranially are numerous and show variability in terms of field amplitude and morphology. Therefore, visual marking can be highly subjective and time consuming. In this study, we applied an automated spike classification algorithm, Wave_clus (WC), to IEDs marked visually on icEEG data acquired during simultaneous fMRI acquisition. The motivation of this work is to determine whether using a potentially more consistent and unbiased automated approach can produce more biologically meaningful BOLD patterns compared to the BOLD patterns obtained based on the conventional, visual classification. METHODS: We analysed simultaneous icEEG-fMRI data from eight patients with severe drug resistant epilepsy, and who subsequently underwent resective surgery that resulted in a good outcome: confirmed epileptogenic zone (EZ). For each patient two fMRI analyses were performed: one based on the conventional visual IED classification and the other based on the automated classification. We used the concordance of the IED-related BOLD maps with the confirmed EZ as an indication of their biological meaning, which we compared for the automated and visual classifications for all IED originating in the EZ. RESULTS: Across the group, the visual and automated classifications resulted in 32 and 24 EZ IED classes respectively, for which 75% vs 83% of the corresponding BOLD maps were concordant. At the single-subject level, the BOLD maps for the automated approach had greater concordance in four patients, and less concordance in one patient, compared to those obtained using the conventional visual classification, and equal concordance for three remaining patients. These differences did not reach statistical significance. CONCLUSION: We found automated IED classification on icEEG data recorded during fMRI to be feasible and to result in IED-related BOLD maps that may contain similar or greater biological meaning compared to the conventional approach in the majority of the cases studied. We anticipate that this approach will help to gain significant new insights into the brain networks associated with IEDs and in relation to postsurgical outcome.

Inequalities in Young Adult Health Insurance Coverage Post-federal Health Reform.

BACKGROUND: Uninsurance for young adults (YAs) was greatly reduced by the Affordable Care Act (ACA). However, reforms may not be equally beneficial for all YAs and certain policies may exacerbate, rather than resolve, pre-existing disparities. OBJECTIVE: To investigate inequalities in YAs' insurance coverage pre- (2000-2010) and post-federal health reforms (dependent coverage expansion, 2010-2013, and Medicaid/Marketplace expansions, 2014-2016), among a nationally representative sample. DESIGN: A difference-in-differences estimator (controlling for sociodemographics) was used to determine the effects of the ACA for young adults (ages 19-25) compared to adolescents (ages 13-18) and older YA (ages 26-30) counterparts; triple-difference estimators quantified differential policy effects by sociodemographics. PARTICIPANTS: Three hundred eighty-seven thousand six hundred thirty-five participants in the 2000-2016 National Health Interview Survey. MAIN MEASURES: Respondents reported their health insurance coverage types during the last 12 months, reasons uninsured, and detailed sociodemographics. KEY RESULTS: An adjusted difference-in-differences estimator quantified a 12.3 percentage point increase (p < 0.0001) in full-year coverage post-ACA for YAs compared to older counterparts, driven by increases in employer-sponsored private insurance while younger and older youth saw larger gains in Medicaid coverage. Triple-difference estimators identified subgroups experiencing less beneficial dependent coverage expansion effects, including females, lower socioeconomic status, non-citizens, non-English speakers, and several racial/ethnic minority groups. Later ACA reforms (Marketplace/Medicaid expansions) mitigated many of these widening disparities. CONCLUSION: While the ACA significantly impacted YA insurance coverage, these gains were not of equal magnitude for all YAs and disparities remain. As such, more work needs to be done to ensure optimal and equitable access to high-quality, affordable insurance for all YAs.

Prediction of PM2.5 along urban highway corridor under mixed traffic conditions using CALINE4 model.

The present study deals with spatial-temporal distribution of PM2.5 along a highly trafficked national highway corridor (NH-2) in Delhi, India. Population residing in areas near roads and highways of high vehicular activities are exposed to high levels of PM2.5 resulting in various health issues. The spatial extent of PM2.5 has been assessed with the help of CALINE4 model. Various input parameters of the model were estimated and used to predict PM2.5 concentration along the selected highway corridor. The results indicated that there are many factors involved which affects the prediction of PM2.5 concentration by CALINE4 model. In fact, these factors either not considered by model or have little influence on model's prediction capabilities. Therefore, in the present study CALINE4 model performance was observed to be unsatisfactory for prediction of PM2.5 concentration.

Microplastics pollution in the Asian water tower: Source, environmental distribution and proposed mitigation strategy.

Microplastics generated from fragmentation of leftover plastics and industrial waste has reached in the remotely located Asian water tower (AWT) region, the 3rd pole of earth and origin site of several freshwater rivers. The accumulation of microplastics in AWT ecosystem has potential to alter the climatic condition contributing in global warming and disturbing the biodiversity structural dynamics. The present paper provides a comprehensive critical discussion over quantitative assessment of microplastics in different ecosystems (i.e. river, lakes, sediment and snow or glacier) of AWT. The hydrodynamic fate and transport of microplastics and their ecological impact on hydromorphology and biodiversity of AWT has been exemplified. Furthermore, key challenges, perspectives and research directions are identified to mitigate microplastics associated problems. During survey, the coloured polyethylene and polyurethane fibers are the predominant microplastics found in most areas of AWT. These bio-accumulated MPs alter the rhizospheric community structure and deteriorate nitrogen fixation process in plants. Significance in climate change, MPs pollution is enhancing the emissions of greenhouse gases (NH3 by ∼34% and CH4 by ∼9%), contributing in global warming. Considering the seriousness of MPs pollution, this review study can enlighten the pathways to investigate the effect of MPs and to develop monitoring tools and sustainable remediation technologies with feasible regulatory strategies maintaining the natural significance of AWT region.

Systemic lupus erythematosus associated with erythema multiforme: A rare case report of Rowell's syndrome.

Key Clinical Message: Although it is very uncommon, SLE may initially present with recurrent episodes of EM-like rash. Despite the various possibilities underlying their association, prompt identification, and treatment of SLE in patients presenting with EM is important to prevent death or serious organ damage. Abstract: Rowell's syndrome (RS) is an uncommon presentation of systemic lupus erythematosus (SLE) with erythema multiforme (EM)-like lesions associated with specific serological changes, including positive rheumatoid factor (RF), speckled antinuclear antibody (ANA), positive rheumatoid factor, or anti-La antibodies in the serum. Our case, a 41-year-old male, presented with features of EM. Upon investigation, we identified underlying systemic lupus erythematosus, marking a rare instance of SLE presenting for the first time as EM. Classical or true EM is precipitated by trigger factors such as infective agents like the herpes simplex virus, Mycoplasma pneumoniae, drugs like anticonvulsants, antibiotics, and non-steroid anti-inflammatory drugs, any underlying malignancy, or connective tissue disorders, and is not associated with any specific serological abnormalities. EM cases associated with LE lesions where an EM trigger factor is missing are considered an RS diagnostic criterion. In this case report, the importance of considering SLE in patients presenting initially with recurrent episodes of EM-like rash is emphasized. RS should be considered, especially when there is no evidence of triggering factors. Early diagnosis and prompt treatment of SLE are crucial to preventing death and irreversible organ damage.

Bronchopleural fistula associated persistent pneumothorax in a patient recovering from COVID-19 pneumonia: A case report.

Key Clinical Message: Pneumothorax and bronchopleural fistula (BPF) are potentially fatal complications that can occur in patients with COVID-19 pneumonia. Early detection, appropriate treatment, and consideration of surgical intervention are necessary for optimum outcomes. Introduction: Healthcare professionals face complex challenges as a result of the rare emergence of pneumothorax among the variety of COVID-19 complications, including severe viral pneumonia. Case History: A 57-year-old male with multiple comorbidities diagnosed with COVID-19 pneumonia was admitted to our center and exhibited bilateral crepitations. During hospitalization, the patient developed right-sided pneumothorax that persisted despite chest tube insertion was linked to the presence of BPF. Discussion: The occurrence of pneumothorax in COVID-19 patients is relatively rare risk factors for which are not yet fully understood, although smoking history may play a role. Conservative management is recommended for asymptomatic cases, while intercostal drainage is necessary for symptomatic patients. Surgical intervention may be required to manage the BPF in some instances. Conclusion: Pneumothorax and BPF are rare but potentially life-threatening complications in patients recovering from COVID-19 pneumonia. Early recognition, appropriate treatment, and consideration of surgical intervention are crucial for optimizing patient outcomes.

Vitamin B12 deficiency in an infant with neurological and hematological findings: A case report.

Key Clinical Message: It is important for pregnant and breastfeeding women who adhere to a strict vegetarian diet to take appropriate steps to avoid vitamin B12 deficiency in their infants. Abstract: Vitamin B12 deficiency is rare during infancy. The initial symptoms of this deficiency are subtle and may include irritability, failure to thrive with a decline in growth rate, apathy, anorexia, refusal of solid foods, megaloblastic anemia, and developmental regression. The case presented here involves an 8-month-old male infant who showed neurological symptoms such as decreased activity, increased drowsiness, and reduced interaction with parents, which were ultimately linked to a deficiency of cobalamin (vitamin B12). Early recognition of this condition is critical because it is reversible. Therefore, pregnant and lactating women who follow a strict vegetarian diet should take necessary measures to prevent vitamin B12 deficiency in infants.

Intestinal tuberculosis can masquerade as Crohn's disease: A teachable moment.

Intestinal tuberculosis and Crohn's disease are chronic granulomatous diseases with similar clinical presentations and can mimic one another. Their treatment modalities are completely different; however, sometimes it is challenging to differentiate them. We report a case of a 51-year-old female presenting with abdominal pain and on-and-off diarrhea for 4 years with weight loss. Clinical symptoms along with multiple aphthous ulcers in the terminal ileum and negative tuberculin test favored the diagnosis of Crohn's disease. The patient did not respond to steroids. A repeat colonoscopy with acid-fast bacilli stain showed Mycobacterium tuberculosis. This case highlights that acid-fast bacilli culture and tuberculosis polymerase chain reaction to confirm or rule out the diagnosis of intestinal tuberculosis in all patients suspected of Crohn's disease.

Coexistence of cerebral venous thrombosis and dural arteriovenous fistula in an adolescent: A case report.

Key Clinical Message: Clinicians should consider central venous thrombosis (CVT) as a differential diagnosis in young adolescents with persistent headaches. It is essential to assess for concurrent CVT and dural arteriovenous fistula (DAVF), particularly in those with a history of CVT. Abstract: Cerebral venous thrombosis (CVT) and dural arteriovenous fistula (DAVF) are uncommon vascular disorders with diverse clinical presentations. The coexistence of CVT and DAVF is a rare but important association that may impact the management and prognosis of affected patients. Prothrombotic conditions generally ranging from acquired to genetic, oral contraceptives, malignancy, puerperium, infection, and head injury are the common risk factors for cerebral venous thrombosis. Here, we present a case of 18 years males who developed recurrent cerebral thrombosis on the background of the presence of an arteriovenous fistula.

Dolutegravir-induced acquired sideroblastic anemia in a HIV positive patient: A challenging hematologic complication.

Dolutegravir, the most recent antiretroviral drug with high efficacy, good tolerability, infrequent drug-drug interactions, and a favorable safety profile has not been reported in current literature as a cause of acquired sideroblastic anemia. Here, we present a 35-year-old male patient who was diagnosed with acquired sideroblastic anemia to Dolutegravir therapy.

An educational intervention to increase internists' confidence with and provision of preventive services to adolescents and young adults.

BACKGROUND: Internal medicine (IM) physicians report inadequate preparation to care for adolescents and young adults. PURPOSE: The aim is to (a) improve IM residents' comfort and confidence caring for adolescents/young adults and (b) increase the percentage of adolescent/young adult patients receiving preventive healthcare. METHODS: Fifty-two PGY1 IM residents were assigned to treatment or control groups. Residents in the treatment group interviewed and received feedback from adolescent instructors. We developed a survey to measure residents' comfort and confidence caring for adolescents/young adults and evaluated their adherence to screening guidelines for patients ages 16 to 26. RESULTS: Significantly more residents in the intervention group felt confident identifying sexually transmitted infections (STIs) and substance abuse and treating STIs, substance abuse, and depression compared to residents in the control group. Residents in the intervention group were no more likely to screen adolescents/young adults for Chlamydia, HIV, alcohol misuse, or depression in the 6 months following the intervention. CONCLUSIONS: An educational intervention utilizing adolescent instructors improves resident confidence but does not increase adherence to screening guidelines.

Implementation and first experiences with a multimodal mentorship curriculum for medicine-paediatrics residents.

INTRODUCTION: Mentorship increases trainee productivity, promotes career satisfaction and reduces burnout. Beginning in 2016, our Medicine-Paediatrics residency program developed and implemented a longitudinal mentorship curriculum among trainees. We report initial experiences with that program and discuss potential future directions. CURRICULUM STRUCTURE AND METHOD OF IMPLEMENTATION: We implemented and adapted a peer mentorship model and expanded it to include guest lectures and workshops centred around 13 core topics. Our expanded model included five longitudinal components: (1) peer mentorship; (2) virtual check-ins with residency leadership; (3) focussed didactics and workshops; (4) small-group dinners highlighting different career paths; and (5) dedicated faculty who pair residents with mentors based on common interests. We compared annual survey results on resident satisfaction with program mentorship, using chi-square and fisher's exact tests to assess statistically significant differences pre- (2012-2016) and post-intervention (2016-2020). RESULTS: We analysed 112 responses with annual response rate varying between 41.2% and 100%. Overall satisfaction with mentorship improved from 57.6% to 73.4% (p = .53), satisfaction with emotional support improved from 63.1% to 71.6% (p = .21), and satisfaction with career-specific mentorship improved from 48.5% to 59.5% (p = .70). Residents reported consistently high satisfaction with peer mentorship (77.8%-100%). The percent of residents reporting they had identified a career mentor increased from 60.0% in 2017 to 88.9% in 2019, which was sustained at 90.0% in 2020. CONCLUSION: We report our experience in implementing and adapting a mentorship curriculum for resident physicians in a single training program, including transitioning to a primarily online-based platform at the outset of the SARS-CoV-2 pandemic. Our results showed a trend towards improvement in resident satisfaction with overall and career-specific mentorship, as well as improved emotional support. Future work is needed using more objective outcome markers among a larger and more diverse group of residents. KEY MESSAGESAmong resident physicians in a single training program, a mix of mentor-mentee dyads, group-based peer mentoring and a structured curriculum has shown promise in improving resident-reported satisfaction with programmatic mentorshipWhile we attempted to adapt the mentorship curriculum to an online platform with the development of the SARS-CoV-2 pandemic, reported satisfaction in overall mentorship and emotional support decreased in comparison to the prior year, an important focus for future work.

Lyonia ovalifolia (Angeri) poisoning: A case report.

Lyonia ovalifolia (angeri) is a deciduous tree whose shoot and leaves are toxic. Its chemical constituents include grayanane diterpenoids, lyoniol A, and other toxic compounds. Young children might consume it intentionally or unintentionally, with subsequent adverse health outcomes and even mortality depending on the amount ingested. We present a case of an adolescent girl who developed poisoning on ingestion of angeri leaves.

Identifying and Analyzing Systems Failures: An Interactive, Experiential Learning Approach to Quality Improvement for Clerkship-Level Medical Students.

Introduction: Medical students are positioned to observe, document, and explore opportunities to improve patient safety and quality in their institutions. Medical schools are introducing quality improvement (QI) knowledge and skills in the preclinical classrooms, yet few provide opportunities to apply these tools in the clinical setting. Methods: Clerkship students participated in two 1-hour sessions, organized in groups of 12-15 students, led by faculty with QI expertise. The sessions in the module introduced core concepts in QI and patient safety, while drawing on students' own clinical experiences. Students identified a system failure they encountered in their own clinical setting/practice and analyzed contributing factors using the 5 Whys Tool. We evaluated the efficacy of the two-session module with a pre- and postsurvey of students' self-reported change in knowledge, skills, and attitudes. Surveys also assessed students' satisfaction with module content and format. Faculty perspectives were solicited by email. Results: In April-May 2019, 59 students at a large US medical school participated. Of students, 73% and 53% completed pre- and postsurveys, respectively. All students submitted a report of an identified systems failure and their analysis of contributing factors. Students' self-rated knowledge and skills increased significantly. Students preferred active engagement compared to passive learning. Students and faculty identified areas for future module improvement. Discussion: The educational program was well received and increased students' knowledge and confidence in core concepts of QI and safety. The module addressed the requirement for graduating students to identify safety incidents and contribute to a culture of QI.
