We live in a tumultuous time for politics across the country. Although our country may remain divided on key issues, we can all agree that with rapid legislative changes and dynamic dialogue about an uncertain future, it is ever more important for people to engage with legislators and lawmakers to shape the future they want to live in.

Even in medicine, at all levels, physicians continue to step into the role of policy makers and leaders; currently, the 115th United States Congress has three physicians in the Senate and 12 physicians in the House of Representatives. As a medical student, I feel compelled to stay informed and engaged on issues within and beyond the realm of health care, and I am beginning to reach out and discover new opportunities to learn about the world of policy. One of those opportunities has been through MedChi.

The Medical and Chirurgical Faculty of the State of Maryland, or MedChi for short, is officially known as the Maryland State Medical Society, which dates back to its origins in 1799. The mission of MedChi is to “serve as Maryland's foremost advocate and resource for physicians, their patients, and the public health.” MedChi serves as an advocacy body and resource center for over 22,000 licensed physicians, 24 sub-medical societies , and is a component of the American Medical Association.

As a medical student, I feel compelled to stay informed and engaged on issues within and beyond the realm of health care, and I am beginning to reach out and discover new opportunities to learn about the world of policy. I first became involved in MedChi simply by responding to an email invitation sent out to our medical school to sit in on a General Assembly meeting of the Maryland state government, a body that MedChi advises regarding medically-related legislation. As I quickly learned, MedChi, although primarily for practicing physicians, is extremely receptive to students in training. Beyond being offered free and full membership into the society, we were personally welcomed into the meeting by the CEO of MedChi, Gene Ransom III, who educated us about MedChi, set up meetings for us to meet legislators and even gave us his personal contact information.

As a first-year medical student, I traveled to Annapolis, Md., and met with a few delegates in the General Assembly who were physicians by training. I spoke with them about their role as physician legislators, and also sat in on a House of Delegates and Senate meeting as they voted on key statewide legislation. I then had the opportunity to attend the MedChi House of Delegates meeting, a MedChi Presidential Gala and a recap of legislation meeting, where I learned about current legislation being passed internally to MedChi, as well as the future of MedChi.

This has been an incredible learning experience. I’ve already begun to form a network of politicians and physicians who understand the physician’s role in tomorrow’s policy-making, and I’ve experienced legislation in action, firsthand. Furthermore, I’m planning on attending the American Medical Association annual conference next month to submit a resolution, a piece of legislation that could impact the policies of the AMA’s Medical Student Senate and, eventually, perhaps influence AMA and even national policy.

Although I’m still unclear about what my future holds, this experience has given me an insight into the career path of being a physician-politician. Whether this manifests as an elected position or simply being engaged in leadership and governance, I know that this exposure in my training will lead to lifelong skills and lessons.

The competitive drive is a double-edged sword: Fighting for success or superiority sharpens our mental acuity and increases motivation, while concurrently inducing anxiety and decreasing inhibitions. Success in fast-paced. Intensive careers such as business, law, science and medicine require using this competitive spirit to drive higher performance and production. Yet this drive to succeed can prove costly and may also lead to burnout, career changes, and—more worrisome—dishonesty.

business people running on a trackAs the new generation of trainees, we’re growing in an environment that fosters collaboration, but the post-training hunt for jobs has never been more cutthroat. Therefore, it’s imperative that we understand how to stimulate our competitive drive to excel without crashing down on the other side.

Competition in the workplace and education systems is still a hotly contested issue. On the one hand, many managers and educators argue that competition brings out the best in their employees and students, and the competitive drive can be exploited beyond what’s expected. These leaders often employ tactics that openly compare production, such as workplace contests, class-rankings, and grading, on a curve. Other leaders believe that direct competition adversely affects employee and student performance. So, instead, they might keep bonuses and rankings secret, while rewarding broad collaboration. Unsurprisingly, data supporting one tactic over the other have been mixed.

drive to succeed can be troubling.Perspective May Impact Success

Recently, sociologists have begun to examine how the framing of competition in both the workplace and the classroom impacts success. In one study, employees were given a hypothetical challenge in which they were told their sales numbers would be compared with their colleagues at the end of a trial month. The workers were divided into two groups: Half were told their success during that month would determine how high above average their bonuses would be, while the other half were informed that if they scored lower than average, they would risk performance reviews and termination.

After completing the study, the researchers reported an interesting and relevant phenomenon. The positively motivated first group significantly increased their output during the experiment and engaged in a variety of creative behaviors to achieve their numbers. The other group—those threatened with negative ramifications—reported higher levels of anxiety and stress, and primarily focused on working longer, harder hours, rather than exploring creative solutions. Of course, in our own lives, competition is nearly always framed in both the positive (career success!) and the negative (failing) simultaneously. Therefore, whether we are aided or hindered by competition largely depends on our interpretation of each challenge.

The Dark Side of Academic Competition

In the experiment described above, the researchers reported one additional significant difference between the two groups: Those threatened with failure were more likely to engage in unethical behaviors. This aspect of human nature poses a serious risk in high-level, fast-paced career fields such as science and medicine. Research moves quickly, and the “publish or perish” motto has never been more true. Medical jobs are hard to come by, and without superb grades, it may be hard to access your ideal career. In fact, with the current aggressively competitive funding environment, and the consequences of losing so serious, many journals are reporting significantly increased levels of fraud and paper retractions.

A number of researchers are investigating this dark side of academic competition and have made a number of recommendations. Most involve identifying ways to reduce the cutthroat pressure trainees constantly face, such as getting rid of class rankings and de-emphasizing the number of published papers needed, as well as fostering a stronger spirit of collaboration throughout the scientific and medical communities. Realistically, however, high-stakes competition will likely never vanish from our culture. So it behooves us to learn how to harness this innate drive to improve our chances for success.

A sizeable crowd of over two hundred attendees gathered in Turner Auditorium on April 18, 2017, to hear discussions on mood disorders at the 31st Annual Mood Disorders Research/Education Symposium, sponsored by the Johns Hopkins Mood Disorders Center.

 Mood disorders, which encompass major depression, anxiety disorder, and bipolar disorder, as well as a spectrum of mood dysregulation conditions, affect up to 20.8% of Americans at any given point in their lifetimes.Mood disorders, which encompass major depression, anxiety disorder and bipolar disorder, as well as a spectrum of mood dysregulation conditions, affect up to 20.8 percent of Americans at any given point in their lifetimes (1). According to the World Health Organization, mood disorders as a group are also the leading cause of disability and decreased quality of life among Americans ages 15-44 (2). While the staple of treatment involves talk therapy and pharmacological agents, the field of mood disorders has undergone big changes in recent years, with renewed research in the electrical-circuit-based biology underlying these mental illnesses as well as more options for treatment, such as mindfulness and meditation.

The recent Mood Disorders Research/Education Symposium consisted of dynamic expert speakers from the psychiatry departments of Johns Hopkins and other highly acclaimed research institutions, including the University of Oxford and Georgetown University School of Medicine. Likewise, the topics of the mini lectures were equally diverse, ranging from expositions on ongoing research studies to patient and family spotlights that were reminiscent of the multi-dimensional and patient-oriented interviews, historically an integral part of the way psychiatry is practiced at Johns Hopkins, conducted within the units in the Meyer building.

With discipline and practice, transcendental meditation may be a potent tool to combat the anxiety-laden and reactionary aspects of major depression with which some patients may struggle.I arrived from work just in time to listen to Dr. Norman Rosenthal, known for describing seasonal affective disorder, discussed the value of transcendental meditation. With discipline and practice, transcendental meditation may be a potent tool to combat the anxiety-laden and reactionary aspects of major depression with which some patients may struggle. Dr. Guy Goodwin delivered a presentation on how smartphones could tap into a new aspect of monitoring and potentially treating psychiatric disorders, such as tracking the mood lability experienced by borderline patients. Technology, such as text messaging to monitor mood and apps for stress management, is becoming an increasingly appealing avenue to transform care for patients with mood disorders.

As a neuroscience and English literature double major from college, I paid particular attention to the talk on female poets and mania by Dr. Kay Jamison, professor of psychiatry at Johns Hopkins and author of several well-known books on her personal experience as well as profiles on artists and thinkers who have struggled with mental illness. I had read and included excerpts from her autobiography, An Unquiet Mind, in my undergraduate thesis on illness narratives, drawn to her earnest descriptions of living and thriving with bipolar disorder. Writing appeared to be a particularly effective and eloquent avenue to communicate her experience with a wide audience. On that spring afternoon at Hopkins, Dr. Jamison’s presentation also tied writing and art into a broader discussion about mental health, highlighting quotations by women writers, such as Sylvia Plath and Virginia Woolf, and showcasing the rich and varied lives and talents sufferers from mental illness held. Her lecture encapsulated an underlying theme of the symposium—that patients are more than their psychiatric disorders.

Hopefully soon, and with the aid of symposiums such as the one the Hopkins Mood Disorders Center organizes yearly, patients, family members and doctors will all benefit from strides in understanding mood disorders and their impact on patients. As Dr. Hope Jahren, author of the bestselling memoir Lab Girl, admits during her frank keynote interview at the conclusion of the symposium, “I’m not like this. This [bipolar disorder] isn’t me. … [and] empathy makes the wall between me and the world … a lot more permeable.”

Each Tuesday, I read the New York Times science section over a cup of coffee and a protein bar. Last week’s article, “Hunched over his microscope, he sketched the secrets of how the brain worked,” exhibits the father of neuroscience, Ramon y Cajal’s, 19th century drawings and elucidations of the neuronal interconnectivity that wires our brain. He understood and predicted fundamental aspects of neuroscience prior to the advent of confocal and two-photon microscopy and complex genetic tools.

Thinking young monkey.Now, in 2017, the latest edition of Neuron features “Long-term two-photon imaging in Awake Macaque Monkey” by Ming Li and colleagues from Peking University in Beijing, China. The authors detail their solutions to technical challenges that have prevented successful, long-term, single cell live imaging in awake macaque monkeys. The new techniques featured in the article allow for visualizing individual neurons and dendrites in awake monkeys for months. This advance is revolutionary to the fields of cellular and behavioral neuroscience and enables live access to macaque circuitry, allowing researchers to study higher cognitive function through imaging and recording neuronal circuits in vivo.

Currently, in two-photon in vivo imaging, a cranial window providing imaging access to the brain area of interest is surgically implanted. High quality, long-term imaging in macaques has been limited by the fast membrane regeneration following cranial window implantation. Further, sizeable brain movements in awake behaving monkeys, as a result of physical or respiratory activity, have impeded successful live imaging. Finally, poor labeling of genetically encoded indicators has prevented adequate activity and individual neuron detection.

The authors combatted these challenges and detailed their surgical and imaging methods in this groundbreaking paper. Their long-term macaque imaging strategy involved two surgical procedures that utilize genetically modified adeno-associated viruses (AAVs) that encode a visual marker, often a fluorescent protein, to visualize a specific protein or molecule. With this methodology, they were able to record activity and perform live imaging in the intact macaque brain. Specifically, they used AAVs to report calcium activity as a read out for neuronal activity while the monkeys performed visualization tasks. They carried out these experiments over extraordinarily long periods of time and published results from experiments conducted for up to four to six months!

This is an incredible advance within the field of neuroscience. Researchers can now, in real time, visualize a synapse firing and detect a physiological response during completion of a specific task. Beyond visualizing neuronal activity, the authors were able to resolve individual dendrites using single-cell electroporation to deliver a mixture of inducible AAVs to express fluorescent calcium indicators. This is an incredible advance within the field of neuroscience. Researchers can now, in real time, visualize a synapse firing and detect a physiological response during completion of a specific task.

Hunched over their microscopes, Li and colleagues are beginning to detail how the macaque brain works. Instead of looking at fixed and stained brain sections, we can look inside the awake monkey brain and understand the firing patterns that underlie task completion. Their work begins to bridge the longstanding gap between genetics and cognition. Where will these technologies take us next?

Children who experience traumatic experiences are known to have long-term negative health effects, including mental, behavioral and physical issues. Mindfulness interventions have proven successful in adults and those dealing with trauma to negate some of the effects of distress. It is suggested that mindfulness could be utilized in children with adverse childhood experiences to also curb negative health effects.

Adverse Childhood Experiences

Did you know: Studies conducted in schools practicing mindfulness have shown reduced classroom behavior problems and stress.There are many categories of adverse childhood experiences (ACEs) which a child may experience personally, or observe through a loved one. These include, but are not limited to: neglect, abuse (physical, emotional, sexual), violence, mental illness, incarceration, drug problems and low socioeconomic status. Prolonged stress can be psychologically and physically problematic, and can manifest as increased inflammation, neurological changes, and dysfunction of the endocrine system. ACEs are common: A CDC study found 69 percent of those examined in five states reported at least one incidence. ACEs tend to occur together, and more ACEs decrease overall health and well-being. ACEs have also been linked to an increased risk for migraines, insomnia, some cancers, learning and behavior problems, and suicide, as well as predispositions to behaviors leading to obesity or smoking.

Mindfulness and Traumatic Experiences

In a recent review by Robin Ortiz and Erica Sibinga of The Johns Hopkins Hospital, the authors determined that mindfulness intervention could prevent the negative side effects of ACEs. Mindfulness is found to be beneficial by redirecting the negative response to trauma as well as destressing the individual to hinder long-term effects of trauma. Mindfulness has proven a successful coping mechanism in women survivors of sexual abuse, incarcerated women, veterans with PTSD, and the general population by increasing resiliency. The practice has been shown to reduce inflammation, alter immunity, and decrease biological aging.

adding just 10-15 minutes of mindfulness to your day can make a significant impact on your stress levels. Try strategies like starting your day with a basic yoga sun salutation, taking a break to check in with your breathing. Doing a body scan paying attention to any tension or stress and relaxing at the end of the day with a guided meditation.

Practicing Mindfulness

Derived from Buddhist tradition, mindfulness is the practice of being fully aware of the present moment in a non-judgmental manner. Mindfulness can be intentionally practiced in structured training programs. Outside of structured practice, mindfulness can be achieved through art therapy, yoga, group therapy, and other focuses on mind and body. Practicing mindfulness has been shown to increase resiliency. Resilience lies in the ability to effectively cope with a traumatic experience. After many traumatic experiences, the survivor may try to dissociate from the trauma, which prevents helpful processing of the event. Mindfulness brings attention and awareness to the traumatic event, which can help with coping and increase resilience.

Utilizing Mindfulness for ACEs

Employing mindfulness techniques in everyday life can help survivors of traumatic experiences, as well as benefit the general public to reduce stress. Focusing on introducing mindfulness into your busy day, or encouraging others who are struggling to bring awareness, can help everyone to negate the long-term negative side effects of stress.

I am sitting in one of the most beautiful architectural marvels I have ever seen: the iconic Rose Main Reading Room of the New York Public Library. A thoughtless turn of the head while stretching my neck and I catch a glimpse of centuries of knowledge in their primordial form — first edition journals and volumes neatly displayed in stacks of thousands. I could look up and be mesmerized by a scene that is reminiscent of a trip I once took to the Sistine Chapel in Rome, with a ceiling inlaid by golden frames sculpted around angels and flowers that adorn portraits of rose-colored clouds.

But I do not. I am instead studying for my boards and repetitively reading about Bacteroides fragilis and glycogen storage disorders. A headache builds as I enter my seventh hour of studying that day, and even then I wave the headache away as I try to recall the mechanism of how amitriptyline reduces chronic pain from tension headaches. My sandpaper eyes are forced to stay open as my ciliary muscles try to accommodate my struggle.

Indeed, studying is a struggle.

quote: "I greet the sun and see past its farewell each day with my study guide in hand. Flashcards accompany my meals and walks have functionally become DVT prophylaxis rather than enjoyable excursions."As medical students, we are no strangers to studying. To get into medical school, we must first do relatively well in undergraduate classes and receive an acceptable score on the Medical College Admission Test, or MCAT. Afterward, we continue to take exams during our preclinical and clinical years in medical school, with boards and licensing exams to follow for the rest of our careers. Indeed, between the time we enter medical school to when we emerge as attending physicians, we will have taken well over 30 exams. But my current adversary is considered one of the most important exams we take as future physicians. The first national board medical exam, Step 1, is the equivalent of the SAT to high school students. It is a strong determining factor for medical residencies and serves as one of two major quantitative measures of a candidate’s appeal — the other being clinical grades.

And so I study. I greet the sun and see past its farewell each day with my study guide in hand. Flashcards accompany my meals and walks have functionally become DVT prophylaxis rather than enjoyable excursions. I try my best to remain focused and keep what I learned three weeks ago from falling through the seemingly ever-expanding sieve that is my brain. But this is what I’m supposed to do. I’m supposed to study so I can take this test. But even as I repeat this mantra, something is off.

When I decided to come to medical school, I did so because of two broad reasons: I wanted to help others and I loved learning medicine. Just two years ago, I would gleefully read the latest articles on neuroscience or immunology in my spare time and marvel at the complexity of our bodies. I took joy in understanding how much there was to learn and loved the challenge of learning. In my mind, every opportunity to learn was a chance to become a better doctor. But while those patterns continued in medical school, my enthusiasm slowly began to temper as I found myself reading more out of obligation than enjoyment. And it was through this insidious slope that I found myself, here today in this beautiful library, woefully anticipating how much there is to still learn. Even as these thoughts continue to percolate, I remember there was once a time when I would have taken a brief pause after every new fact and whistled in appreciation.

So I stop.

I try to whistle, at least metaphorically.

quote: "I think about the extraocular muscles I just used, the atelectasis my sigh just prevented, and the prefrontal cortex that helped me synthesize these thoughts. And I cannot help but smile."I crank my head up and force these tired eyes to appreciate this library. The ceiling is truly beautiful. I turn to the history engraved to my left. Colors of aged red, mysterious blue and forest green sharpen into focus. And then, as I slowly move my field of vision back to my books, I take a deep breath. I strive to look beyond bullet points of information and recapture some of the wonder I once had. I think about the extraocular muscles I just used, the atelectasis my sigh just prevented, and the prefrontal cortex that helped me synthesize these thoughts.

Studying will always be a part of medicine. The onus is on us for why we study. There are exams, of course, and these milestones can be as much a measure of our fatigue as they are of our professional progression. But we can choose to appreciate what we learn as a privilege. We can eagerly study in anticipation of being better physicians and scientists, all while marveling in the wonderment of it all.

All we need is a reminder to take a moment and look up.

The oral exam. The candidacy exam. The comprehensive exam. There are many names for it, but all pre-doctoral graduate students come to fear it. At different universities, this pivotal exam happens at different points in your Ph.D. At Johns Hopkins, most students will take their candidacy exam after their main courses are finished, but before they have completed the majority of their thesis work.

Tired student studyingThis is usually somewhere between the end of the first and second year of graduate school. The examiners are a committee made up of faculty members, who prepare questions on both general aspects of the student’s field of study and specific topics pertaining to the student’s thesis in order to assess their readiness to continue the bulk of their thesis research.

I am currently a third-year student in the human genetics pre-doctoral training program. For students in my program, the oral exam takes place at the end of our second year, when we have finished most of our classes. We prepare a ten-minute talk on a topic of our choice (usually our thesis work), which is followed by two hours of questions from our committee members. I took the exam last year, and it was a harrowing, but valuable, experience.

Here are some tips that helped me while I was studying:

  1. Set aside dedicated time to study. You might be thinking, “But I just can’t take time off from my lab!” You need to prioritize, and your oral exam is of the utmost importance. You can’t continue on in your Ph.D. program, or in your thesis lab, without passing this exam. You might be thinking that you don’t need to study very much, but it’s likely that you haven’t realized how much you don’t know or may have forgotten since your coursework. It wasn’t until I sat down to make my study guide that I became overwhelmed by the sheer amount of information I was expected to master. Don’t be afraid to take time away from your lab work in order to thoroughly prepare; most advisors have also served on many exam committees and are usually very supportive about the process.
  1. Rehearse explaining the specifics of your lab’s specialty. Because you may be starting off your exam with a short talk or written proposal regarding your work, you will need to know the details about relevant methods and hypotheses. Usually, you are working with this material on a daily basis. Even so, make sure to practice explaining the complicated intricacies of your project that you might not talk about every day. Since most members of your lab know these areas already, it can be easy to forget that they are not common knowledge to researchers outside of your specific field.
  1. Try to familiarize yourself with the basics on most, if not every, topic from your classes. Your examining committee will have their own set of expertise. They might ask you questions from subjects of their specialty or content from lectures they gave during your courses. The professors will not expect you to be an expert on every subject, but you should at least be able to explain major ideas, broad concepts and a range of methods.
  1. Set aside dedicated time to relax. This might be the most important tip! Especially if you are highly motivated, don’t forget to take a break. Your brain needs time to let new concepts sink in. This way, you can incorporate new facts with what you have already studied. Taking a nap, eating healthy food and meeting up with friends can all help to take your mind off the stress of the oral exam. Find what works best for you.
  1. Ask for help! Other students have gone through this as well. They can help give you tips on what to study or where to go on campus for a quiet environment. You might also want to have older students ask you questions in exam format, so you can practice answering out loud. If you start feeling overwhelmed, don’t be afraid to ask your program coordinator, your advisor, or your lab mates for help! They might be able to set you up with a tutor for difficult topics, give you more time away from lab, or help you with time-sensitive experiments while you are out of the lab studying.

Your candidacy exam will be hard, but it’s supposed to be! Your committee will push the boundaries of what you know. Just remember that this trial brings you one step closer to completing your Ph.D.

Imagine going to the doctor to be tested for HIV in sub-Saharan Africa. You will likely have to travel a long distance to get to a clinic, and, once you arrive, your blood will be drawn and sent to a central testing laboratory for analysis. You will then have to wait for the results to be delivered to the clinic and return to the clinic for your diagnosis. In Zambia, it takes approximately 92 days for this process to be completed. When you are an HIV-positive mother waiting to find out if your newborn child needs antiretroviral therapy, each of those 92 days can mean the difference between life and death for your baby.

Management of infectious diseases such as HIV in sub-Saharan Africa has been a major part of the career of William Moss, M.D., a professor of epidemiology at the Johns Hopkins Bloomberg School of Public Health. He works closely with the Johns Hopkins research field site in Macha, Zambia, to study the epidemiology behind infectious diseases that devastate Africa.

Mobile phones help get an earlier HIV diagnosis

New work from Moss and his group focuses on finding ways to shorten the 92-day wait for HIV test results. Capitalizing on the increasing amount of technology available in rural Zambia, Moss and colleagues conducted a study using text messaging to deliver HIV test results directly from the central testing lab to mothers or rural health clinics. The results, published in the April issue of BMC Pediatrics, found that by sending a text message directly to the mother, they could reduce the time from sample collection to receipt of diagnosis to just 18 days.

Unfortunately, the use of mobile phones is still not widespread; only 30 percent of mothers in the study had ever used one. Luckily, the local clinics do have mobile phones, so delivering results via text can still decrease the time to diagnosis, to approximately 36 days. By cutting 56 days off the wait for diagnosis, HIV-positive children can receive antiretroviral therapy nearly two months earlier. Reducing the time to treatment significantly ameliorates the clinical symptoms of HIV infection and prevents the progression to AIDS, vastly improving their quality of live and longevity.

As noted by Moss, implementation of the mobile phone messaging system for test result delivery was by no means trivial. It required the hiring and training of new staff as well as the purchase of mobile phones and “talk time” for the phones. Other major obstacles for mobile phone messaging systems include unreliable network coverage throughout rural areas, lack of digital literacy and skills, and the large gender gap: Men are much more likely to have mobile phones, while women are responsible for the children’s health. Additionally, villagers were often skeptical of the benefits of using a mobile phone when they had relied on their traditional system for years. However, with the right funding and infrastructure, the utilization of technology throughout Africa has the power to have significant and widespread impacts on health care. Studies such as this highlight the great potential of available technology to encourage governments and private investors to take note and get involved. Someday soon, nationwide mobile phone messaging systems may become common place, drastically cutting the time to diagnosis and improving each individual’s access to care and treatment.

Over 3,000 years old, Judaism is one of the oldest monotheistic religions. Calling oneself a Jew draws on a rich history and a continually growing set of religious texts; it is a link to a culture of resilience and a peoplehood that have withstood incredible persecution and social restriction, immigration and assimilation. Thus, for many, being Jewish is much more than having a certain faith tradition.

In the early 1900s, Jewish students filled almost half of medical school spots in America. Although the religious composition of medical students has since shifted, there remain strong sentiments in the Jewish religion that encourage careers in medicine. Judaism defines the human body as sacred; learning how to heal it is viewed as tantamount to “doing God’s work” by preserving another human’s life. Ilan Caplan, a second-year medical student, described how his faith compels him to one day become a family physician: “[The body] is the vessel that God has given souls to walk around in.  Therefore, to try to keep the body as healthy as possible is itself a holy act.”

Being a Jewish practitioner in medicine can also confer a responsibility towards social justice. A large part of how Zackary Berger, M.D., Ph.D., conceives his work as a physician is through advocacy and political work. “There is a prophetic ethical tradition of trying to improve the world,” he notes. For example, in Exodus (one of the books of the Torah), the prophet Moses writes of how God says, “I will bring you [the Jews] out from under the yoke of the Egyptians. I will free you from being slaves to them.” The theme of freedom from slavery underlies Passover, one of the major Jewish holidays.

quote: [The body] is the vessel that God has given souls to walk around in. Therefore, to try to keep the body as healthy as possible is itself a holy act.This responsibility toward the other similarly motivates Maya Siegel, a third-year medical student. When asked about how her religious beliefs influence her decision to pursue a career in medicine, Siegel responded, “Social medicine and systems of injustice affect our patients... I am also motivated by Tikkun Olam, the concept that the world was created imperfect, and we as humans are required to work to make the world better.” Compelled by the importance of tradition, ritual and community in the lives of her Jewish peers, Siegel is active in the Jewish Students Association at the Johns Hopkins University School of Medicine as well as in the local Jewish community in Baltimore.

Eric Weaver, a second-year medical student, also feels a deep connection with the rituals and traditions of Judaism; however, his personal practices have more recently been influenced by an affinity with Buddhism, and especially the practice of meditation.  Rather than being unable to reconcile the two religions, Weaver points to the rare openness that Judaism has toward other ideas and beliefs. In fact, it is important to note that calling oneself Jewish doesn’t necessitate a belief in the existence of God or the divine; rather, Judaism is, in general, more interested in the “practice” of religion (e.g. rituals, tradition). Weaver finds that his current identity lies in a delicate interweaving of the anchoring and focus of Buddhism, the culture and traditions of Judaism, and the value placed on kindness and love in both.

With regards to incorporating his faith in his medical practice, Berger chuckles when he shares that wearing his yarmulke (a cap that sits on the crown of the head) is often a conversation starter for patients to ask questions about his religious identity.  In general, he urges us to see religion not as an outlandish practice but as common and important to the lives of others. “Understanding a patient’s religion is understanding their spiritual needs. It is an important part of interacting with every patient.”

About this series:

Although medicine is often seen as a field that is distinct from religion, religious beliefs have a significant impact on the way physicians and medical students approach their training, interactions with patients, and understandings of disease and death. Biomedical Odyssey bloggers Rabia Karani and Stephanie Zuo have created a short blog series on faith and medicine to give you a glimpse into the worlds of Johns Hopkins students who have been influenced strongly by and/or are actively practicing their faiths. 

We hope that you come away with a deeper understanding of the profound impact and immense strength that arises when peoples of faith seek to do good work in the medical field with all their hearts, minds and souls.

The contagious yawn is a well-known component of the communal human experience that transcends languages and cultures. We joke about it in offices and dedicate Mythbusters episodes to understanding its frequency, and researchers have even shown its ability to pass between species (try yawning in front of your dog or cat and see how long it takes them to follow suit). But there are other contagious behaviors as well: for example, cringing at someone else’s pain, as well as itching and scratching. The mere mention of lice can send hands directly to hair, and observing somebody scratching their head vastly increases your likelihood to do the same. These actions are not in response to any direct itching stimulus, but simply due to verbal or observable suggestion.

Contagious itch, in contrast, occurs because visual signals from nearby peers engage numerous brain regions that then modulate connections usually reserved for direct, reflexive signaling. The root of these actions is generally attributed to “mirror neurons,” a distinct population of cells that fire both when an animal performs a specific behavior, and while observing another animal perform the same behavior. The evolutionary functions of these mirror neurons are still vigorously debated, and they have been implicated in a wide variety of socio-cognitive behaviors including imitation-learning, perception-action coding, and even empathy in humans. However, because thus far these neurons have only been identified in primates, the tools for studying them in a lab are limited.

To more directly examine the roots of contagious behaviors, researchers sought a behavior they could induce and observe in mice, which would allow them to take advantage of the rich genetic toolbox available for this model organism). By exposing wild-type mice exhibiting normal scratching behavior to chronically scratching mice, they demonstrated a strong imitative itch response that had not been previously shown. Importantly, these mice still itched even when they only saw a video of another mouse scratching (something I’m sure we can all empathize with, having yawned or scratched in imitation of a character on TV).  In these “imitating” mice, the authors found gastrin-releasing peptide (GRP) positive cells in a region of the brain called the suprachiasmatic nucleus (SCN) were more active during the itching behavior. Although the SCN is most often studied in the context of its role in pace-making in the circadian rhythm, these cells also receive direct visual input, and the authors hypothesized they may be acting as a relay station between visual information and behavioral response.

By working with mice genetically engineered to express either a light-inducible or light-repressible protein only in GRP+ neurons, the authors were able to specifically activate or inactivate only the GRP+ neurons by exposing them to a specific wavelength of light (called optogenetic manipulation). They then showed that specific activation of these neurons resulted in a significantly increased scratch response when the animal was viewing another scratching mouse, while optogenetic silencing or ablation of GRP+ neurons resulted in a significant decrease in this imitative behavior. By demonstrating both positive and negative control of this behavior through GRP+ neurons, their role is shown to be integral to contagious itch in mice.

These findings point in an interesting direction by demonstrating a hard-coded, biological signal for mammalian contagious behaviors. Often, yawning after someone, or “feeling someone’s pain,”  considered an empathetic reaction, involving higher cognitive functions.  But this research suggests these reactions are more reflexive and autonomous in nature, and likely evolved within our ancestors well before humans could appreciate the humor of a 3 p.m. yawn traveling throughout the entire office as if carried on the wind.
