Calciphylaxis and Kidney Disease: A Review.

Calciphylaxis is a life-threatening complication most often associated with chronic kidney disease that occurs as a result of the deposition of calcium in dermal and adipose microvasculature. However, this condition may also be seen in patients with acute kidney injury. The high morbidity and mortality rates associated with calciphylaxis highlight the importance to correctly diagnose and treat this condition. However, calciphylaxis remains a diagnosis that may be clinically challenging to make. Here, we review the literature on uremic calciphylaxis with a focus on its pathophysiology, clinical presentation, advances in diagnostic tools, and treatment strategies. We also discuss the unique histopathological features of calciphylaxis and contrast it with those of other forms of general vessel calcification. This review emphasizes the need for multidisciplinary collaboration including nephrology, dermatology, and palliative care to ultimately provide the best possible care to patients with calciphylaxis.

Craniosynostosis: Are Online Resources Readable?

OBJECTIVE: This study aims to analyze the readability of online craniosynostosis materials from the perspective of a caregiver, and to assess if readability levels conform to recommendations by the American Medical Association (AMA) and National Institutes of Health (NIH). DESIGN: This is a cross-sectional investigation in which an internet search was conducted simulating the search terms of a caregiver of a patient with craniosynostosis. The first three pages of resulting records were calculated for comprehension ease using validated readability indices. Records were also classified by author type, including hospital system, national health organization, academic journal, and other. MAIN OUTCOME MEASURES: Flesch-Kincaid Reading Grade Level, Gunning fog Index, SMOG Index, and Coleman Liau Index. RESULTS: Thirty records were identified for which the mean readability level was 12.8 ± 2.6 grade levels (range, 7.6-15.9). There were no significant differences in mean readability across readability indices or author type. None of the thirty records met levels recommended by the AMA or NIH and were 6.8 grade levels above these guidelines on average. CONCLUSIONS: Online material pertaining to craniosynostosis is written, on average, at the reading level of a first-year undergraduate student. The AMA and NIH recommend that articles be written at approximately a sixth-grade reading level to promote comprehension. Therefore, there is significant room for improvement of current online materials. Authors should consider consulting publicly available guides in preparing future resources.

Trends in clinical presentation of children with COVID-19: a systematic review of individual participant data.

BACKGROUND: There are sparse patient-level data available for children with novel coronavirus disease (COVID-19). Therefore, there is an urgent need for an updated systematic literature review that analyzes individual children rather than aggregated data in broad age groups. METHODS: Six databases (MEDLINE, Scopus, Web of Science, CINAHL, Google Scholar, medRxiv) were searched for studies indexed from January 1 to May 15, 2020, with MeSH terms: children, pediatrics, COVID-19, SARS-CoV-2. 1241 records were identified, of which only unique papers in English with individual patient information and documented COVID-19 testing were included. This review of 22 eligible studies followed Preferred Reporting Items for Systematic Review and Meta-Analyses of individual participant data guidelines. RESULTS: A total of 123 patients from five countries were identified. 46% were females. The median age was 5 years (IQR = 8). At presentation, 62% had a fever, 32% had a cough, 58% had a single symptom, and 21% were asymptomatic. Abnormal chest imaging was seen in 62% (65/105) of imaged and 76.9% (20/26) of asymptomatic children. A minority of children had elevated platelets, CRP, lactate dehydrogenase, and D-dimer. CONCLUSION: Data from this independent participant data systematic review revealed that the majority of children with COVID-19 presented with either no symptoms or a single, non-respiratory symptom. IMPACT: This systematic review revealed that the majority of children with COVID-19 presented with either no symptoms or a single, non-respiratory symptom. By using an independent participant data approach, this analysis underscores the challenge of diagnosing COVID-19 in pediatric patients due to the wide variety of symptoms and seemingly poor correlation of imaging findings with symptomatic disease. The data presented from individual patients from case series or cohort studies add more granularity to the current description of pediatric COVID-19.

Predictors of COVID-19 severity: A literature review.

The coronavirus disease 2019 (COVID-19) pandemic is a rapidly evolving global emergency that continues to strain healthcare systems. Emerging research describes a plethora of patient factors-including demographic, clinical, immunologic, hematological, biochemical, and radiographic findings-that may be of utility to clinicians to predict COVID-19 severity and mortality. We present a synthesis of the current literature pertaining to factors predictive of COVID-19 clinical course and outcomes. Findings associated with increased disease severity and/or mortality include age > 55 years, multiple pre-existing comorbidities, hypoxia, specific computed tomography findings indicative of extensive lung involvement, diverse laboratory test abnormalities, and biomarkers of end-organ dysfunction. Hypothesis-driven research is critical to identify the key evidence-based prognostic factors that will inform the design of intervention studies to improve the outcomes of patients with COVID-19 and to appropriately allocate scarce resources.

Delayed medical care due to transportation barriers among US children with atopic dermatitis.

Our objective was to examine the prevalence and predictors of delayed medical care due to transportation barriers among children with atopic dermatitis (AD) living in the United States (US). We analyzed data from the 1998-2018 National Health Interview Survey, a nationally representative survey of US households. In 2018, transport-delayed care was reported for 3.4% of US children with AD, representing approximately 279,000 children annually given the National Health Interview Survey's weighted survey design, and was more common among patients of lower socioeconomic status. Targeted interventions aimed at reducing transportation barriers to healthcare among at-risk AD patients may reduce health disparities related to AD.

Neurological Involvement in COVID-19 and Potential Mechanisms: A Review.

As the current understanding of COVID-19 continues to evolve, a synthesis of the literature on the neurological impact of this novel virus may help inform clinical management and highlight potentially important avenues of investigation. Additionally, understanding the potential mechanisms of neurologic injury may guide efforts to better detect and ameliorate these complications. In this review, we synthesize a range of clinical observations and initial case series describing potential neurologic manifestations of COVID-19 and place these observations in the context of coronavirus neuro-pathophysiology as it may relate to SARS-CoV-2 infection. Reported nervous system manifestations range from anosmia and ageusia, to cerebral hemorrhage and infarction. While the volume of COVID-19-related case studies continues to grow, previous work examining related viruses suggests potential mechanisms through which the novel coronavirus may impact the CNS and result in neurological complications. Namely, animal studies examining the SARS-CoV have implicated the angiotensin-converting-enzyme-2 receptor as a mediator of coronavirus-related neuronal damage and have shown that SARS-CoV can infect cerebrovascular endothelium and brain parenchyma, the latter predominantly in the medial temporal lobe, resulting in apoptosis and necrosis. Human postmortem brain studies indicate that human coronavirus variants and SARS-CoV can infect neurons and glia, implying SARS-CoV-2 may have similar neurovirulence. Additionally, studies have demonstrated an increase in cytokine serum levels as a result of SARS-CoV infection, consistent with the notion that cytokine overproduction and toxicity may be a relevant potential mechanism of neurologic injury, paralleling a known pathway of pulmonary injury. We also discuss evidence that suggests that SARS-CoV-2 may be a vasculotropic and neurotropic virus. Early reports suggest COVID-19 may be associated with severe neurologic complications, and several plausible mechanisms exist to account for these observations. A heightened awareness of the potential for neurologic involvement and further investigation into the relevant pathophysiology will be necessary to understand and ultimately mitigate SARS-CoV-2-associated neurologic injury.

SARS-CoV-2 transmission: a sociological review.

The current pandemic is defined by the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that can lead to coronavirus disease 2019 (COVID-19). How is SARS-CoV-2 transmitted? In this review, we use a global lens to examine the sociological contexts that are potentially and systematically involved in high rates of SARS-CoV-2 transmission, including lack of personal protective equipment, population density and confinement. Altogether, this review provides an in-depth conspectus of the current literature regarding how SARS-CoV-2 disproportionately impacts many minority communities. By contextualising and disambiguating transmission risks that are particularly prominent for disadvantaged populations, this review can assist public health efforts throughout and beyond the COVID-19 pandemic.

Cardiac involvement in COVID-19 patients: Risk factors, predictors, and complications: A review.

BACKGROUND: Respiratory complications have been well remarked in the novel coronavirus disease (SARS-CoV-2/COVID-19), yet an emerging body of research indicates that cardiac involvement may be implicated in poor outcomes for these patients. AIMS: This review seeks to gather and distill the existing body of literature that describes the cardiac implications of COVID-19. MATERIALS AND METHODS: The English literature was reviewed for papers dealing with the cardiac effects of COVID-19. RESULTS: Notably, COVID-19 patients with pre-existing cardiovascular disease are counted in greater frequency in intensive care unit settings, and ultimately suffer greater rates of mortality. Other studies have noted cardiac presentations for COVID-19, rather than respiratory, such as acute pericarditis and left ventricular dysfunction. In some patients there has been evidence of acute myocardial injury, with correspondingly increased serum troponin I levels. With regard to surgical interventions, there is a dearth of data describing myocardial protection during cardiac surgery for COVID-19 patients. Although some insights have been garnered in the study of cardiovascular diseases for these patients, these insights remain fragmented and have yet to cement clear guidelines for actionable clinical practice. CONCLUSION: While some information is available, further studies are imperative for a more cohesive understanding of the cardiac pathophysiology in COVID-19 patients to promote more informed treatment and, ultimately, better clinical outcomes.

Exploring the Beliefs, Values, and Understanding of Quality End-of-Life Care in the Latino Community: A Spanish-Language Qualitative Study.

Context: Hospice services are underutilized by the Latino community in the United States. Previous research has identified that language is a key barrier contributing to disparities. However, very few studies have been conducted in Spanish to specifically explore other barriers to hospice enrollment or values related to end-of-life (EOL) care in this community. Here, we remove the language barrier in order to gain an in-depth understanding of what members of the diverse Latino community in one state in the USA considers high quality EOL and barriers to hospice. Methods: This exploratory semi-structured individual interview study of Latino community members was conducted in Spanish. Interviews were audio-recorded, transcribed verbatim and translated to English. Transcripts were analyzed by three researchers, using a grounded-theory approach to identify themes and sub-themes. Main Findings: Six major themes emerged: (1) concept of "a good death"-spiritual peace, family/community connection, no burdens left behind; (2) centrality of family; (3) lack of knowledge about hospice/palliative care; (4) Spanish language as critical; (5) communication style differences; and (6) necessity for cultural understanding. The central theme of "a good death" was closely linked to having the entire family physically and emotionally present. The four other themes represent interrelated, compounding barriers to achieving this "good death." Principal Conclusions: Healthcare providers and the Latino community can work together to decrease hospice utilization disparities by: actively involving family at every step; addressing misconceptions regarding hospice; conducting important conversations in Spanish; and improving provider skills in culturally sensitive care, including communication style.

Kaposi Sarcoma Associated with Tofacitinib Use in a Patient with Rheumatoid Arthritis.

Kaposi sarcoma is a rare vascular malignancy associated with HHV-8 infection. Four variants of Kaposi sarcoma have been described: Classic, African, HIV-associated, and iatrogenic. Iatrogenic Kaposi sarcoma is typically associated with immunosuppression and organ transplantation. We present a case of iatrogenic Kaposi sarcoma associated with tofacitinib therapy. A 69-year-old woman with rheumatoid arthritis receiving tofacitinib presented with multiple firm, purple-red nodules and brown plaques on the left lower extremity and a single lesion on the right medial calf. Clinicopathologic correlation confirmed a diagnosis of Kaposi sarcoma. Tofacitinib was discontinued and she was started on Alitretinoin 0.1% gel bid. The purple-red Kaposi sarcoma nodules decreased 50% in size after 4 months and resolved at 1 year off the tofacitinib and initiation of alitretinoin gel. As the use of immunomodulators and biologics continues to expand, awareness of this association is important for prompt diagnosis and management.

Pembrolizumab-induced Toxic Epidermal Necrolysis in a Patient with Metastatic Esophageal Adenocarcinoma.

Adverse cutaneous reactions associated with the immune checkpoint inhibitor (ICI) pembrolizumab are well documented, yet life-threatening reactions such as Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) are infrequent.1,2 We present a case of pembrolizumab-induced TEN in a patient with metastatic esophageal adenocarcinoma who was successfully treated with cyclosporine and systemic corticosteroids.

Examining the First Peer-to-Peer Mentorship Program (F1Doctors) for International Medical Students.

In this study, we report international medical students in the United States and conduct an analysis of the first, peer-to-peer, national mentorship program for international medical students and international pre-med applicants in the US (F1Doctors). We used analyzed survey data collected through F1Doctors and the Association of American Medical Colleges yearly matriculation reports. Results indicated that the average college grade point average (GPA) and Medical College Admission Test score (MCAT) of international applicants was higher than that of all applicants. Additionally, non-US applicants reported facing numerous unique challenges such as limited access to extracurricular opportunities and difficulty finding mentors who are familiar with the application process. International applicants have the potential to increase the diversity of healthcare professionals, and F1Doctors is the first platform to support international healthcare applicants in the US.

Confidence and knowledge in emergency management among medical students across Colombia: A role for the WHO basic emergency care course.

INTRODUCTION: Globally, medical students have demonstrated knowledge gaps in emergency care and acute stabilization. In Colombia, new graduates provide care for vulnerable populations. The World Health Organization (WHO) Basic Emergency Care (BEC) course trains frontline providers with limited resources in the management of acute illness and injury. While this course may serve medical students as adjunct to current curriculum, its utility in this learner group has not been investigated. This study performs a baseline assessment of knowledge and confidence in emergency management taught in the BEC amongst medical students in Colombia. METHODS: A validated, cross-sectional survey assessing knowledge and confidence of emergency care congruent with BEC content was electronically administered to graduating medical students across Colombia. Knowledge was evaluated via 15 multiple choice questions and confidence via 13 questions using 100 mm visual analog scales. Mean knowledge and confidence scores were compared across demographics, geography and prior training using Chi-Squared or one-way ANOVA analyses. RESULTS: Data were gathered from 468 graduating medical students at 36 institutions. The mean knowledge score was 59.9% ± 23% (95% CI 57.8-62.0%); the mean confidence score was 59.6 mm ±16.7 mm (95% CI 58.1-61.2). Increasing knowledge and confidence scores were associated with prior completion of emergency management training courses (p<0.0001). CONCLUSION: Knowledge and confidence levels of emergency care management for graduating medical students across Colombia demonstrated room for additional, specialized training. Higher scores were seen in groups that had completed emergency care courses. Implementation of the BEC as an adjunct to current curriculum may serve a valuable addition.

An Analysis of Information Sources of YouTube Videos Pertaining to Tattoo Removal: Cross-Sectional Study.

Background: The American Academy of Dermatology and the Food and Drug Administration recommend consultation with a dermatologist prior to undergoing laser tattoo removal. However, non-health care professionals offer tattoo removal. Understanding the information available on the internet for patients regarding tattoo removal is important given that individuals are increasingly consulting digital sources to make decisions regarding skin care. Prior research has identified that YouTube contains misinformation on dermatologic health. Objective: Here, we present a cross-sectional study that determined the sources of information in YouTube videos that discuss tattoo removal and described the content presented to viewers. Methods: Using the query "tattoo removal," we reviewed English-language YouTube videos that explicitly discussed tattoo removal. The following data were recorded: profession of the presenter, tattoo removal method discussed, whether an explicit recommendation to see a dermatologist or physician was present in the video, and number of views. Results: We analyzed 162 YouTube videos. We found that the majority were presented by non-health care professionals (n=125, 77%), with only 4 (3.7%) records of this subset recommending viewers to seek consultation from a dermatologist to ensure safe and adequate tattoo removal. Conclusions: Based on our findings, we recommend that dermatologists and other health care professionals provide high-quality, evidence-based information to viewers on tattoo removal and encourage dermatology societies to share via their social media platforms information about the importance of consulting a dermatologist for tattoo removal.

Increased Temperatures Are Associated with Increased Utilization of Emergency Medical Services in Rhode Island.

BACKGROUND: Increasing temperatures negatively impact health and increases demands on healthcare systems. However, this has been poorly studied in Rhode Island (RI). Here we characterize the impact of heat on emergency medical services (EMS) utilization in RI. METHODS: The Rhode Island National Emergency Services Information System V3 dataset was merged with data from the National Center for Environmental Information of the National Oceanic and Atmospheric Administration from the summers of 2018 and 2019. The outcome of daily mean EMS runs were compared against the exposure increasing daily temperatures, measured as daily maximum, minimum and daily average °F, using Poisson regressions. Patient characteristics were included across temperature models. RESULTS: Increasing daily temperatures were associated with increasing EMS encounters. The adjusted incident rate ratio (IRR) for mean daily EMS encounters by increasing maximum daily temperature was 1.006 (95% CI 1.004-1.007, Table 3). This resulted in a projected 17.2% increase in EMS runs on days with a maximum temperature of 65°F compared to days with a maximum temperature of 95°F. The adjusted IRR for mean daily EMS encounters by the daily minimum temperature was 1.004 (1.003-1.006) and the adjusted IRR for the mean daily EMS encounters by the daily average temperature was 1.006 (1.005-1.008). CONCLUSIONS: Increasing minimum, maximum, and average daily temperatures were associated with increasing EMS utilization across Rhode Island in the summers of 2018 and 2019. Further research into these trends may help with planning and resource allocation as summer temperatures continue to rise.
