RESUMO

Introduction: COVID-19, the infectious disease caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), often presents with a spectrum of symptoms at varying levels of severity, ranging from asymptomatic patients to those with fatal complications, such as myocarditis. With increased availability of COVID-19 vaccines, the awareness of possible side effects has expanded as reports surface. This study reviewed cases of myocarditis following COVID-19 vaccination and with existing literature on COVID-19 infection-induced myocarditis to compare clinical courses and analyze possible mechanisms of action. Methods: A systematic review of literature was conducted to identify published case reports (as of February 3, 2022) pertaining to the development of myocarditis following COVID-19 vaccination with either Pfizer or Moderna for an in-depth analysis. Additional subgroup analyses were conducted based on age, past medical history, vaccine manufacturer, and dose number. Results: There were 53 eligible case reports that were included in this study. Patients were mostly male with a median age of 24 years, and the most reported symptom upon presentation was chest pain. Seventy percent of the cases involved the Pfizer vaccine with a majority of myocarditis developing subsequent to second dose. Resolution of symptoms was achieved in all but one patient. Clinical severity, as measured primarily by left ventricular ejection fraction, appeared to be worse among adult patients than pediatric, as well as for patients with comorbidities. Conclusion: This study revealed an observable association between COVID-19 vaccines and myocarditis. However, the clinical course and prognosis seem favorable and less prevalent than those conferred from natural infection.

RESUMO

The skin is a critical barrier that protects against damage and infection. Within the epidermis and dermis reside γδ T cells that play a variety of key roles in wound healing and tissue homeostasis. Skin-resident γδ T cells require T cell receptor (TCR) ligation, costimulation, and cytokine reception to mediate keratinocyte activity and inflammatory responses at the wound site for proper wound repair. While both epidermal and dermal γδ T cells regulate inflammatory responses in wound healing, the timing and factors produced are distinct. In the absence of growth factors, cytokines, and chemokines produced by γδ T cells, wound repair is negatively impacted. This disruption in γδ T cell function is apparent in metabolic diseases such as obesity and type 2 diabetes. This review provides the current state of knowledge on skin γδ T cell activation, regulation, and function in skin homeostasis and repair in mice and humans. As we uncover more about the complex roles played by γδ T cells in wound healing, novel targets can be discovered for future clinical therapies.

RESUMO

An unsung hero of American orthopedic surgery is the largely forgotten Dr. Newton Melman Shaffer (1846-1928). Upon graduating from medical school at New York University, Shaffer began his career training at the Hospital for the Ruptured and Crippled in 1867. Shaffer then went on to practice at St. Luke's Hospital and New York Orthopaedic Dispensary and Hospital where he became chief. Here, Shaffer made major contributions to the field in treating clubfoot and tuberculosis. He then declared orthopedics as a separate entity from general surgery at the 10th International Medical Congress. He helped start the American Orthopaedic Association to push for the recognition of American orthopedics to the international community. In 1900, Shaffer opened the first state-run hospital for underprivileged children requiring rehabilitation. During his career, Shaffer advocated for conservative orthopedic treatments, aided in the invention of medical devices, contributed largely to academic orthopedics, and successfully advocated for the inception of the field of orthopedic surgery.

RESUMO

Surgery continues to be an increasingly vital component of public health and aspect of patient care in rural communities. An anticipated shortage of surgeons within the next decade in the United States prompts a growing concern for increasing the delivery of essential surgical care to these populations. When considering the existing barriers to surgical healthcare in rural communities, there is a sense of urgency to identify innovative approaches that will promote a sustainable surgeon workforce. A narrative review was conducted to investigate the current state of access to essential surgical care in rural communities. Qualitative and quantitative data were collected to better understand the key issues in rural healthcare and to provide statistical data related to the status of the surgical workforce. With the anticipated shortage of surgeons in both rural and urban areas, this review highlights the importance of enacting immediate measures to address the concern. This review has accomplished the initial objectives of gaining a better understanding of the current state of access to surgical care in rural communities and utilizing this knowledge to provide recommendations to readily attain a sustainable number of rural surgeons. With each approach addressing ways to address the contributory issues to the surgeon shortage, this review reveals a new avenue of integrating valuable aspects from each approach, rather than relying on a single approach. In particular, enhancing the overall pipeline of medical training to attending status may prove to be more beneficial for achieving this goal. Ultimately, this may be accomplished by introducing additional rural surgical mentorship opportunities for medical students, developing a rural surgery fellowship, and incorporating a market-based response that will correspond to attractive incentives that help to retain a sustainable number of surgeons working in rural areas.

RESUMO

Hypertension is the leading preventable risk factor for cardiovascular disease and all-cause mortality worldwide. However, studies have shown increased risk of mortality from heart disease and stroke even within the normal blood pressure (BP) range, starting at BPs above 110-115/70-75 mm Hg. Nutraceuticals, such as vitamins and minerals, have been studied extensively for their efficacy in lowering BP and may be of benefit to the general, normotensive population in achieving optimal BP. Our study investigated the effects of six nutraceuticals (Vitamins: C, D, E; Minerals: Calcium, Magnesium, Potassium) on both systolic blood pressure (SBP) and diastolic blood pressure (DBP) in this population. We performed a systematic review and pairwise meta-analysis for all six supplements versus placebo. Calcium and magnesium achieved significant reductions in both SBP and DBP of -1.37/-1.63 mm Hg and -2.79/-1.56 mm Hg, respectively. Vitamin E and potassium only yielded significant reductions in SBP with values of -1.76 mm Hg and -2.10 mm Hg, respectively. Vitamins C and D were not found to significantly lower either SBP or DBP. Future studies should determine optimal dosage and treatment length for these supplements in the general, normotensive population.

RESUMO

Background The lack of financial literacy among medical students and physicians is a well-documented problem that is yet to be sufficiently addressed. The full immersion of physicians into their scientific education and medical training makes it challenging to also comprehensively learn about personal finance. With the vast debt that most medical students undergo, it is crucial to focus on this issue. Methodology To address this challenge, faculty at The Florida State University College of Medicine (FSU COM) have created a fully online personal finance elective course for fourth-year medical students. This course, titled Personal Finance for the New Physician, focuses on critical fiscal topics that are directly relevant to future doctors. The elective is delivered remotely through the utilization of online discussion boards, weekly video conferences, and recorded lectures by financial experts. This innovative distribution model ensures that busy students can educate themselves regardless of time or location. Results Initially offered in January of 2019, Personal Finance for the New Physician quickly became the most chosen elective at FSU COM. To determine the course's efficacy, students completed a questionnaire at both the start and end of the elective. The results show substantial improvements in fiscal knowledge and confidence in managing personal finances. The average financial competence score of those who completed the course increased from a 2.25/5 to a 4.45/5. Feedback from students so far has been exceedingly positive. Conclusions Personal Finance for the New Physician has been effective at addressing the lack of financial knowledge that is prevalent among medical students. Additionally, the unique online nature of this course would allow for realistic expansion to other medical programs. Course directors will continue to receive feedback from students, financial experts, and physicians to modify and improve the elective.

RESUMO

Identification of ischemia remains critical when assessing individuals presenting with atypical symptoms or in patients with known coronary artery disease (CAD). Several imaging modalities are currently available to attain this diagnostic goal. Unfortunately, not all case presentations are straightforward, particularly when microvascular dysfunction (MVD) is the cause of symptoms in the absence of identifiable epicardial luminal stenosis. Specifically, in such cases, current imaging guidelines do not include stress echocardiography (SE) as a recommended tool when assessing these patients. We present three cases that highlight the utility of SE for identifying MVD and provide mechanistic explanations. We believe that SE should not be completely discarded as an inadequate testing modality; we highlight the potential utility of this imaging modality not only in diagnosing CAD and pre-surgical evaluation of patients but also in identifying patients with MVD.
