Key clinical point: Vaginal breech delivery (VBD) performed under experienced supervision does not significantly increase the risk for negative short-term perinatal outcomes.

Major finding: VBD, elective caesarean section (CS), and emergency CS did not result in any significant difference in the proportion of neonates with a 5-min Apgar score of <3, umbilical arterial pH of <7.00, or the need for admission to the neonatal intensive care unit (all P > .05).

Study details: This single-center, retrospective study included 804 singleton pregnant women with a fetus in breech position at delivery who underwent VBD (n = 433), emergency CS (n = 214), or elective CS (n = 157).

Disclosures: No source of funding was reported. The authors declared no conflicts of interest.

Key clinical point: Intraoperative cell salvage (ICS) is an effective and safe method for blood loss recovery in patients with a high risk for postpartum hemorrhage (PPH) during cesarean section.

Major finding: Patients who underwent ICS vs received allogeneic red blood cell (RBC) transfusion had significantly higher blood cell count, hemoglobin levels, hematocrit, and fibrinogen levels, and shorter prothrombin time, thrombin time, and activated partial thromboplastin time (all P < .05). ICS treatment did not cause any adverse events.

Study details: This prospective randomized controlled study included 130 patients with a high risk for PPH who underwent elective or emergency cesarean section and were randomly assigned (1:1) to undergo ICS (n = 65) or receive allogeneic RBC transfusion (control; n = 65) if the hemoglobin level was <80 g/L during surgery.

A new model for predicting breast cancer risk that is based on standard clinical measures could be used to develop personalized breast screening strategies that are more effective than the current “one size fits all” approach, say researchers.

“Several breast cancer risk prediction models have been created, but we believe this is one of the first models designed to guide breast screening strategies over a person’s lifetime using real data from a screening program,” said study author Javier Louro, PhD, Hospital del Mar Medical Research Institute, Barcelona, Spain.

“Our model might be considered a key for designing personalized screening aimed at reducing the harms and increasing the benefits of mammographic screening,” he said in a statement.

Someone with a low risk “might be offered screening with standard mammography every 3 or 4 years instead of 2 years,” Dr. Louro explained.

“Someone with medium risk might be offered screening with advanced 3D mammography every 3 years, while those at a high risk might be offered a new screening test with mammography or MRI every year.”

However, he cautioned that “all of these strategies are still theoretical and should be studied with regard to their effectiveness.”

Dr. Louro was talking about the new model at the 13th European Breast Cancer Conference.
 

Details of the new prediction model

To develop the new model, Louro and colleagues conducted a retrospective study of 57,411 women who underwent mammography in four counties in Norway between 2007 and 2019 as part of the BreastScreen Norway program, and followed them up to 2022.

The team gathered data on age, breast density, family history of breast cancer, body mass index, age at menarche, alcohol habit, exercise, pregnancy, hormone replacement therapy, and benign breast disease, and compared women with and those without a breast cancer diagnosis.

All of these 10 variables used were found to significantly explain part of the variability in the breast cancer risk.

Overall, the 4-year breast cancer risk predicted by the resulting model varied across the participants, from 0.22% to 7.43%, at a median of 1.10%.

Bootstrap resampling analysis revealed that the model overestimated the risk for breast cancer, at an expected-to-observed ratio of 1.10.

The largest effect on risk was from breast density on mammography. Women with dense breasts were at much higher risk: the adjusted hazard ratio was 1.71 for women with Volpara Density Grade 4 vs Grade 2 and was 1.37 when compared with Grade 3.

Exercise had a large impact on breast cancer risk, the researchers found. Women who exercised for 4 or more hours per week had an adjusted hazard ratio of 0.65 for breast cancer risk compared with women who never exercised. Although this effect of exercise reducing the risk for breast cancer is now widely known, it is not usually included in models that predict breast cancer risk, the team pointed out.

The team concluded that their prediction model could be used to personalize breast screening for women according to their risk assessment, although they acknowledge that more work is needed. This work is based on one screening program in one country, and similar studies in different settings are needed.

Reacting to the findings, Laura Biganzoli, MD, co-chair of the European Breast Cancer Conference and director of the Breast Centre at Santo Stefano Hospital, Prato, Italy, commented, “We know that breast screening programs are beneficial, but we also know that some people will experience potential harms caused by false-positives or overdiagnosis.”

“This research shows how we might be able to identify people with a high risk of breast cancer, but equally how we could identify those with a low risk. So it’s an important step toward personalized screening,” Dr. Biganzoli said.

This study was supported by a grant from Instituto de Salud Carlos III FEDER (grant PI/00047). No relevant financial relationships declared.

A woman who had breast cancer for 23 years, and who had gone through 12 different lines of therapy, has shown a dramatic response to a novel cancer vaccine in a clinical trial.

A recent 6-month follow-up showed no evidence of new or recurrent disease, and scans showed regression of a distant bulky left adrenal metastasis, as well as at other sites.

A small site of residual hypermetabolism remains in the sternum, but this is thought to be related to scar tissue.

The patient, Stephanie Gangi, told Medscape Medical News that, before she entered into the trial for the novel cancer vaccine, she was “mentally and physically exhausted.” She had benefited from being diagnosed with hormone-positive breast cancer just as its treatment was evolving and progressing, which meant that, every time a treatment failed, “there was the next thing to try, which was great and kept me going.”

“But I will admit that, by age 66, and more than 20 years of cancer treatments, I was exhausted.”

Ms. Gangi, a New York City-based poet, essayist, and fiction writer, said she was “cautiously optimistic” about the cancer vaccine, but the “overriding thought was I wanted to avoid chemotherapy.”

“I was not really signing on for great outcomes, I was signing on for something that might keep chemo at bay. The biggest impact so far for me has been that, for the first time in more than a decade, I am not on any medication. That’s really amazing…and that means no side effects,” she said.

Ms. Gangi stopped the vaccine treatment this past July, and just over 3 months later, she is still “wrapping her head around” the fact that her cancer has regressed. “I’ve had breast cancer a long time,” she said, “and you can’t just snap your fingers and be fine.”

Although the two scans that she has had since the trial ended have been “astonishing,” she underlined that this is not about a ‘cure,’ but rather “clearing tumors for the first time in many years.”

“Cancer is sneaky and sinister, and it figures out how to circumvent all kinds of treatments,” she said, adding nevertheless that she is “happy and hopeful, and my family is thrilled, of course.”

Ms. Gangi was classed as having had a partial response to the cancer vaccine, one of a few in a small phase 1/2 trial at the Icahn School of Medicine at Mount Sinai in New York. One other patient also had a partial response, and one patient had a complete response.

However, six patients have progressive disease, and one has stable disease.  

These results come from an interim analysis of 10 patients from the trial, and show a 30% response rate. They were presented at the recent annual meeting of the Society for Immunotherapy of Cancer.

The vaccine that was being tested combines local low-dose radiation, intramural Flt3L, which stimulates dendritic cells, and intravenous poly-ICLC, an immune stimulating factor, with the PD-1 inhibitor pembrolizumab (Keytruda).

The result is that, instead of making a vaccine in a laboratory and administering it, “we’re actually formulating it within the body,” lead author Thomas Marron, MD, PhD, professor of medicine (hematology and medical oncology) at Mount Sinai, said in an interview.

“What people don’t realize,” he said, is that bulky tumor sites contain “a lot of dead tumor, because they grow so fast and in a haphazard way.” This means that the immune system can be recruited to recognize the dead tumor and “gobble up the dead stuff that’s already there,” he added.

The hope is that the immune system will then kill not only “the tumor you are injecting into, but also tumors elsewhere in the body,” Dr. Marron said. “So you’re basically using your body’s own immune system and on and off switches to vaccinate the patient against their cancer.”

Another patient in the trial who had a complete response to the vaccine was William Morrison, with non-Hodgkin lymphoma (NHL).

Mr. Morrison was diagnosed in 2017, at which time he was enrolled onto a phase 1 trial of an earlier version of this novel vaccine treatment regimen. “Basically, they didn’t get the results they were hoping for, and I still had the lymphoma,” he said. In 2018, his indolent follicular lymphoma transformed into an aggressive diffuse large B-cell lymphoma, for which Mr. Morrison was given six cycles of chemotherapy. This put him into remission and cleared his lymphoma.

“But the remission lasted for maybe a little over a year,” he said.

The cancer came back, and at that point he was given the opportunity to enroll in the Mount Sinai trial. At the end of the treatment, “everything was clear.”

“I’ve been for PET scans every 6 months, and I just had a scan done the other week, and everything has been fine…I’ve been pretty excited. I was pretty lucky.”

“This recent one really has worked wonders,” he said, “When they gave me the good news the other day. I felt like a big weight had been lifted.”

Mr. Morrison also said that he did not experience any serious adverse events while being treated with the vaccine. “Other than a few minor things, I tolerated it pretty well,” he said.

In contrast, Ms. Gangi said she experienced “intense” flu-like symptoms that started in the first few days after the treatment and lasted for a couple of days.
 

Need to improve response rate

The current trial achieved responses in 30% of patients, which “is great, [but] we want to be at 100%,” said Dr. Marron.

“What we’re doing in the laboratory right now is using this as an opportunity to study what it is that’s special about those three people who responded and what’s not happening in the other seven people, and we have some initial data that we’re analyzing,” he said.

“We are seeing that the patients who responded have a much more robust response to the Ft3L in particular…and that could suggest that maybe we need a better Ft3L, or we could think about other ways to potentially manipulate this vaccine.

“Most of the patients who are referred to me are people who have run out of options…and that usually means they’ve had many different types of chemotherapy,” Dr. Marron commented. For example, Ms. Gangi had already been through 12 different chemotherapy regimens.

Chemotherapy suppresses the immune system, but it’s not only that — also having an effect are all the other treatments aimed at reducing nausea and allergic reactions to the anti-cancer therapy, Dr. Marron explained.

“By the time that I see a patient,” Dr. Marron said, “oftentimes their immune system is not optimal. So another way in which we would hope to see better responses is by moving this vaccine earlier in the treatment paradigm, and administering it to patients as their first or second treatment.”

Senior author Joshua Brody, MD, director of the Lymphoma Immunotherapy Program at Mount Sinai’s Tisch Cancer Institute, added that it “might be easy” to incorporate the vaccine into earlier lines of therapy.

He said in an interview that both immunotherapy and radiation therapy are “standard” treatments, and the key is “adding multiple ingredients together that don’t have cumulative toxicity.”

“You can’t just chemo one plus chemo two, because they have some of the same toxicities, but the delightful thing here is this therapy had been quite safe.

“So in theory it would be fairly easy to incorporate this into earlier lines of therapy, once we can get a bit more proof of principle,” Dr. Brody said.

Approached for comment, Ann W. Silk, MD, said that the results are “particularly impressive because we know anti-PD-1 plus radiation therapy does not work in hormone-positive breast cancer or lymphoma.”

Dr. Silk, an oncologist at the Dana-Farber Cancer Institute and assistant professor of medicine at Harvard Medical School in Boston, said in an interview that one advantage of this vaccine is that it “is not restricted to a certain number of antigens and does not rely on an algorithm.”

“I would love to see more data in hormone-positive metastatic breast cancer patients,” she added. “I would use this approach after the hormonal treatments stop working, but before chemotherapy.”

Dr. Silk also said that the safety profile “looks quite good, and I imagine this approach would result in a much better quality of life for patients as compared to chemotherapy.”
 

Details of the trial and results

The Mount Sinai researchers had previously developed a personalized genomic cancer vaccine, PGV-001, which showed promise in a phase 1 trial in 13 patients with solid tumors or multiple myeloma and a high risk of recurrence after surgery or autologous stem cell transplant.

Next, they worked to develop the concept further to turn the tumor into its own vaccine, which involved inducing anti-tumor responses in indolent NHL, which typically responds poorly to checkpoint blockade, by combining Ft3L, low-dose irradiation, and poly-ICLC.

The next phase 1 trial showed that this approach was feasible, but preclinical modeling suggested that the addition of PD-1 blockade could improve the cure rates. The researchers therefore conducted the current trial, recruiting 10 patients with indolent NHL, metastatic breast cancer, or head and neck squamous cell carcinoma (HNSCC).

Patients were given local radiation therapy on days 1 and 2, and intramural Ft3L to the same tumor on day 9, followed by eight intravenous injections of poly-ICLC over 6 weeks. On day 23, they received their first of eight doses of pembrolizumab.

Dr. Marron explained that the radiotherapy increases the amount of dead material for the immune system to work on by “killing some of the tumor cells,” adding: “We’re not trying to kill the whole tumor with the radiation…it just starts the process of releasing some more of that dead stuff.”

He explained that Ft3L is a human growth factor that simulates dendritic cells, “which I always say are the professor cells of the immune system,” as they tell the body “what’s good and what’s bad.”

The poly-ICLC is “basically like a fake virus,” Dr. Marron said, as it “turns on those immune cells that have taken up the tumor antigen in the neighborhood” of the tumor, so they “teach the immune system that there is something bad”.

Finally, the pembrolizumab is there to “take the foot off the brake of the immune system” and “grease the wheels a bit more,” he added, even though it does not work in all patients, or in all tumor types, including indolent NHL.

The trial was planned in two phases. In the first part, six patients were enrolled to assess the safety of the approach; the phase 2 stage of the trial followed a Simon’s Two-Stage design, with the aim of recruiting seven patients of each tumor type, followed by a further 12 patients if they showed a response.

The current interim analysis that was presented at the SITC meeting focused on the first 10 patients in the phase 2 part, who were enrolled between April 2019 and July 2022. This included six patients with metastatic breast cancer, three with indolent NHL, and one with HNSCC, all of whom completed their first disease response assessment.

All patients experienced treatment-related adverse events, largely comprising low-grade injection site reactions and flu-like symptoms linked to the poly-ICLC injections.

One patient experienced grade 3 pembrolizumab-related colitis, while another had self-resolving grade 3 fever following poly-ICLC injection.

The study was sponsored by Icahn School of Medicine at Mount Sinai and conducted in collaboration with Merck Sharp & Dohme LLC and Celldex Therapeutics. No relevant financial relationships were reported.

A woman who had breast cancer for 23 years, and who had gone through 12 different lines of therapy, has shown a dramatic response to a novel cancer vaccine in a clinical trial.

A recent 6-month follow-up showed no evidence of new or recurrent disease, and scans showed regression of a distant bulky left adrenal metastasis, as well as at other sites.

A small site of residual hypermetabolism remains in the sternum, but this is thought to be related to scar tissue.

The patient, Stephanie Gangi, told Medscape Medical News that, before she entered into the trial for the novel cancer vaccine, she was “mentally and physically exhausted.” She had benefited from being diagnosed with hormone-positive breast cancer just as its treatment was evolving and progressing, which meant that, every time a treatment failed, “there was the next thing to try, which was great and kept me going.”

“But I will admit that, by age 66, and more than 20 years of cancer treatments, I was exhausted.”

Ms. Gangi, a New York City-based poet, essayist, and fiction writer, said she was “cautiously optimistic” about the cancer vaccine, but the “overriding thought was I wanted to avoid chemotherapy.”

“I was not really signing on for great outcomes, I was signing on for something that might keep chemo at bay. The biggest impact so far for me has been that, for the first time in more than a decade, I am not on any medication. That’s really amazing…and that means no side effects,” she said.

Ms. Gangi stopped the vaccine treatment this past July, and just over 3 months later, she is still “wrapping her head around” the fact that her cancer has regressed. “I’ve had breast cancer a long time,” she said, “and you can’t just snap your fingers and be fine.”

Although the two scans that she has had since the trial ended have been “astonishing,” she underlined that this is not about a ‘cure,’ but rather “clearing tumors for the first time in many years.”

“Cancer is sneaky and sinister, and it figures out how to circumvent all kinds of treatments,” she said, adding nevertheless that she is “happy and hopeful, and my family is thrilled, of course.”

Ms. Gangi was classed as having had a partial response to the cancer vaccine, one of a few in a small phase 1/2 trial at the Icahn School of Medicine at Mount Sinai in New York. One other patient also had a partial response, and one patient had a complete response.

However, six patients have progressive disease, and one has stable disease.  

These results come from an interim analysis of 10 patients from the trial, and show a 30% response rate. They were presented at the recent annual meeting of the Society for Immunotherapy of Cancer.

The vaccine that was being tested combines local low-dose radiation, intramural Flt3L, which stimulates dendritic cells, and intravenous poly-ICLC, an immune stimulating factor, with the PD-1 inhibitor pembrolizumab (Keytruda).

Five pounds of weight gain during the holidays is a disproven myth that pops up annually like holiday lights. But before you do a happy dance and pile that extra whipped cream on your pie, you should know two things. One, people do gain weight during the holidays. Two, the extra pounds tend to stick around because most people never lose their holiday weight. Over time, these extra pounds can lead to obesity and weight-related conditions such as diabetes and hypertension.

Let’s be clear. Your weight is one of many markers of your wellness and metabolic health. However, weight changes can indicate that your health is off balance. Holiday weight gain often comes from indulging in increased rich foods, less physical activity, higher stress levels, and sleep disruption.

Optimizing lifestyle factors and trying to lose weight is challenging any time of the year. However, the holiday bustle makes losing weight during this time even more challenging for most people. But maintaining your weight and overall wellness is manageable with three simple shifts in mindset, mindful eating, and meal strategy. Let’s discuss each.
 

Mindset 

From personal and professional experience, I see two primary attitudes regarding holiday eating. They are either “I’ll wait till January to go on a diet” or “I’m on a diet, so I can’t eat anything I like during the holidays.” Both attitude extremes prevent enjoyable and healthy eating during the holidays because they place the focus on food. With both mindsets, food is in control, which leaves you feeling out of control. Rather than having an “all or none” mindset during the holidays, I encourage you to ask yourself:

• “What matters most to me during the holidays?” In a recent survey, 72% of Americans said they look forward to  during the holidays. Although food often accompanies family celebrations, it’s the time with family that matters most. Choose to savor sweet time spent with loved ones instead of stuffing yourself with excess sugary sweets.
• “How can I enjoy myself without food or alcoholic beverages?” So often, we eat or drink certain foods out of habit. Shift your mindset from “we always do this” to “what could we do instead?” Asking this question may be the doorway to creating new, non–food-centered traditions.
• “How can I have the foods I love during the holidays and still meet my weight and wellness goals?” This question helps you create opportunities instead of depriving yourself. Rather than depriving yourself, you could cut back on snacking or reduce your sugar intake elsewhere. Or add an extra workout session or stress reduction practice during the holidays.

Mindful eating 

The purpose of mindful eating isn’t weight loss. Some studies suggest it may help maintain weight. More importantly, mindfulness can improve your relationship with food and promote wellness. Traditional tips for mindful eating include doing the following as you eat: Being present in the moment, not judging your food, slowing down, and savoring the taste of your food. During the holidays, asking additional questions may enhance mindful eating. For instance:

• “Am I eating to avoid uncomfortable emotions?” The holidays can trigger emotions such as grief, sadness, and anxiety. Also, preexisting can worsen.

• “What food or drink do I most enjoy during the holidays?” Trying to resist your favorite holiday treats can be an exhausting test of “willpower.” Eventually,  and psychological reasons, and you “cheat” on your plan to not eat holiday treats. To prevent this painful battle of treat versus cheat, plan to eat your “indulgence food” in moderation. Savor the foods you enjoy. Then cut out the rest of the food you don’t like or feel you must eat because “Aunty Sarah will feel bad.”

Meal strategy

Many holiday treats and parties are unavoidable unless you plan to hide in a cave for the next few weeks. Rather than torturing yourself nibbling on celery and sipping on sparkling water during your holiday event, create a strategy. For 8 years, I’ve been on my weight loss and wellness journey. I have a holiday strategy that helps my patients, clients, and me maintain our weight and wellness during the holidays. One critical part of the strategy is to anticipate indulgence events. Specifically, look at all the planned holiday events and choose three indulgence events. The rest of the time, do your best to stay on your plan. Knowing your indulgence events to look forward to gives you a sense of control over when you indulge. On non-indulgent days, think, “I can eat it but choose not to” instead of the limiting thought, “I can’t eat that.” Choice is a powerful tool. Once at an indulgence event, I focus on mindful eating and enjoying people around me, which cuts down on overeating just because “I can.”

This holiday season is a reunion time for many people, after enduring long separations from family and friends due to the pandemic. Relishing time with loved ones should be your focus during the holidays – not eating yourself into worse health or worrying about dieting. Even if you choose not to make all the shifts in mindset, mindful eating, and meal strategy mentioned, choosing even one change to focus on can help you both enjoy the holidays and have increased control over your weight and wellness. Whatever you do, may you and your loved ones have a safe, healthy, and enjoyable holiday season.

Five pounds of weight gain during the holidays is a disproven myth that pops up annually like holiday lights. But before you do a happy dance and pile that extra whipped cream on your pie, you should know two things. One, people do gain weight during the holidays. Two, the extra pounds tend to stick around because most people never lose their holiday weight. Over time, these extra pounds can lead to obesity and weight-related conditions such as diabetes and hypertension.

Let’s be clear. Your weight is one of many markers of your wellness and metabolic health. However, weight changes can indicate that your health is off balance. Holiday weight gain often comes from indulging in increased rich foods, less physical activity, higher stress levels, and sleep disruption.

Optimizing lifestyle factors and trying to lose weight is challenging any time of the year. However, the holiday bustle makes losing weight during this time even more challenging for most people. But maintaining your weight and overall wellness is manageable with three simple shifts in mindset, mindful eating, and meal strategy. Let’s discuss each.
 

Mindset 

From personal and professional experience, I see two primary attitudes regarding holiday eating. They are either “I’ll wait till January to go on a diet” or “I’m on a diet, so I can’t eat anything I like during the holidays.” Both attitude extremes prevent enjoyable and healthy eating during the holidays because they place the focus on food. With both mindsets, food is in control, which leaves you feeling out of control. Rather than having an “all or none” mindset during the holidays, I encourage you to ask yourself:

• “What matters most to me during the holidays?” In a recent survey, 72% of Americans said they look forward to  during the holidays. Although food often accompanies family celebrations, it’s the time with family that matters most. Choose to savor sweet time spent with loved ones instead of stuffing yourself with excess sugary sweets.
• “How can I enjoy myself without food or alcoholic beverages?” So often, we eat or drink certain foods out of habit. Shift your mindset from “we always do this” to “what could we do instead?” Asking this question may be the doorway to creating new, non–food-centered traditions.
• “How can I have the foods I love during the holidays and still meet my weight and wellness goals?” This question helps you create opportunities instead of depriving yourself. Rather than depriving yourself, you could cut back on snacking or reduce your sugar intake elsewhere. Or add an extra workout session or stress reduction practice during the holidays.

Mindful eating 

The purpose of mindful eating isn’t weight loss. Some studies suggest it may help maintain weight. More importantly, mindfulness can improve your relationship with food and promote wellness. Traditional tips for mindful eating include doing the following as you eat: Being present in the moment, not judging your food, slowing down, and savoring the taste of your food. During the holidays, asking additional questions may enhance mindful eating. For instance:

• “Am I eating to avoid uncomfortable emotions?” The holidays can trigger emotions such as grief, sadness, and anxiety. Also, preexisting can worsen. Decadent foods become a quick fix leading to more emotional eating during this season. Addressing these emotions can help you avoid overeating during the holidays.

Farshad Fani Marvasti, MD, MPH, is part of a growing movement to fundamentally shift medical education to include training on how to cook healthy meals.

The way he sees it, the stakes couldn’t be higher. He believes doctors need to see food as medicine to be able to stem the tide of chronic disease.

About 6 in 10 adults in the United States live with chronic diseases, according to the Centers for Disease Control and Prevention, costing $4.1 trillion in annual health care costs. Adult obesity rates are rising, as are obesity-related conditions such as heart disease, stroke, type 2 diabetes, and certain types of cancer.

To turn the tide, Dr. Marvasti created a culinary medicine program in 2020 in collaboration with the University of Arizona Cooperative Extension and local chefs.

Dr. Marvasti, who is board certified in family medicine, graduated from the University of Arizona, Phoenix, where he serves as the director of the medical school’s Culinary Medicine Program.

The program offers an elective course for third- and fourth-year medical students, which introduces the evidence-based field of culinary medicine. Dr Marvasti’s goal is for the course to teach students how to use this science and the joy of cooking to improve long-term health outcomes for their patients.

As part of Dr. Marvasti’s program, students learn cooking fundamentals through chef demonstrations and hands-on practice – to teach students how food can be used to prevent and treat many chronic diseases.

One of the dishes students learn to make includes a quinoa salad made with cucumber, onion, bell peppers, corn, cherry tomatoes, beans, garlic, olive oil, and lemon juice. Another recipe includes a healthier take on dessert: Dark chocolate mousse made with three large, ripe avocados, dark chocolate powder, three tablespoons of agave or maple, coconut cream, nondairy milk, salt, and vanilla. Dr. Marvasti and his team are set to build out the existing program to develop additional resources for medically underserved and rural communities in Arizona, according to a statement from the university. These plans will be funded by a $750,000 grant from Novo Nordisk.

“We’re going to develop an open education curriculum to share, so it’s open access to everyone,” said Dr. Marvasti, who is also director of Public Health, Prevention and Health Promotion and an associate professor at the university. “It can be adaptable at the undergraduate, graduate, and postgraduate level.”

Dr. Marvasti and his colleagues at the University of Arizona aren’t alone. In fact, culinary medicine programs are sprouting some serious legs.
 

Culinary medicine programs catch on

Jaclyn Albin, MD, CCMS, an associate professor in the departments of internal medicine and pediatrics at UT Southwestern Medical Center, Dallas, conducted a scoping review of the literature on culinary medicine programs for medical students.* Her purpose was to learn how the programs were structured and how they assessed student knowledge and attitudes regarding nutrition counseling for patients.

Dr. Albin and her colleagues performed an initial literature search between June 1 and Aug. 1, 2020, of papers published between Jan. 1, 2012, and Aug. 1, 2020 – excluding some newer programs such as the one at the University of Arizona. The results of their research were published in Academic Medicine.

Ultimately, the authors identified and examined 34 programs offering medical student–focused culinary medicine courses.

Program instructors typically included a team of physicians, dietitians, chefs, and other professionals, the study found.

Most program participants exclusively taught medical students, though the training years of participants varied among programs, and they included first-, second-, third-, and fourth-year students. Some programs allowed students from outside their respective medical school to participate in the trainings.

As for the formats of the program, most included cohorts of 10-20 students attending multiple 2- to 3-hour sessions over the course of several months. The University of Alabama at Birmingham offers one of the longest courses, which spans 4-5 months, according to the paper. In contrast, the University of Rochester (N.Y.) program offers only a 1-day lab divided into four sessions, with each session lasting about 2 hours.

The culinary medicine programs’ course sessions tended to include a 10- to 30-minute didactic session involving videos, research articles, culinary theories, and other lectures, a 60- to 90-minute hands-on cooking session, and a 30-minute discussion around nutrition, culture, and patient care.

Most programs used pre- and post-program surveys to evaluate outcomes, though results varied between programs, according to the study. While each program evaluation had different metrics, the surveys generally revealed students felt more confident discussing dietary interventions with patients and in their own cooking skills following completion.
 

Course correction

Most of those programs are unfunded or minimally funded, Dr. Albin said.

Her own program, which is immensely popular with medical students, is one she teaches on a volunteer basis.

“I do this for free, in the evenings, because I believe in it,” she said.

Medical school education real estate is limited, so convincing medical schools to add something to the curriculum is difficult, Dr. Albin noted.

But it’s worth it, she said, because nutrition is the underpinning of so many diseases.

“Food is the top risk factor for early death in the U.S.,” Dr. Albin said. “I like to say that five times in a row. People have not digested it.”

During her culinary medicine courses, she also asks her medical students: “Who is comfortable in the kitchen?” Some sheepishly raise their hands, she said. Some don’t. Many don’t know anything about cooking.

Then she teaches students about healthy food and how to make it. As part of her program, medical students are given a pantry starter kit with olive oil and a variety of spices to take home and use.

Some recipes Dr. Albin teaches includes mango chili shrimp salad with lime vinaigrette, eggplant sliders, yellow vegetable curry, and strawberry banana chia pudding.

“If you figure out how to do it for your own busy, everyday life, you are now empowered to tell someone else about it,” she said.
 

A dietitian’s involvement

Milette Siler, RD, LD, CCMS, works with Dr. Albin to educate medical students and patients about food as medicine. A significant chunk of her job involves teaching future doctors what dietitians do.

When the class starts, many students don’t know two of the five basic things dietitians do, Ms. Siler said. By the end of the class, all students know what a dietitian does.

That’s important as students go on to become doctors.

“For us to remove barriers to care, we have to acknowledge most patients’ entry into health care is their physician,” she said. “The dietitian is often a referral. Doctors need to know enough to do no harm.”

Clinicians are often siloed, she said, and the key to better serving patients is partnership, transparency, and relationships. “I think everybody is at a point where everyone is saying what we’re doing isn’t working,” she said. “The American public deserves better, physicians deserve better, and clinicians deserve better.”
 

Popular with students

While the old guard has been slow to embrace the shift, her students have helped drive the growth of the culinary medicine field, Dr. Albin said.

“They are not settling for the inadequacy that somehow the rest of us did,” she continued. “I’m so hopeful for the future of the health system. We have a generation of people who will not stand for neglecting the most vital elements.”

Lyndon Bui, a second-year medical student at the University of Arizona, Phoenix, is an example of one of these people.

As a member of a culinary medicine interest group on campus, he said, he has learned a lot about the importance of diet for long-term health. This has given him confidence to talk about food and nutrition.

His group does cooking demos at the Phoenix Farmers Market using food from various local vendors. They usually make a salad from local greens and cook seasonal veggies in a stir fry, he said.

They’ve previously made salad with microgreens – young seedlings of edible vegetables and herbs – and pomegranate seeds with a honey mustard vinaigrette, eggplant or cucumber, and hummus on pita bread, as well as almond butter and honey sandwiches, according to the university.

The group also talks with people in the community, answers questions, and learns about community needs.

Mr. Bui’s participation in this group has helped him cultivate a passion for community outreach that he wants to incorporate into his career.

“I feel like I have the knowledge to provide better advice to patients,” he said. “Knowing all these things about food, I feel more comfortable talking about it and more inclined to refer to a dietitian when maybe I wouldn’t have before.”
 

Family physician applauds culinary medicine programs

When Angie Neison, MD, CCMS, went to medical school, she was surprised there wasn’t more education on nutrition.

In fact, on average, physicians receive less than 20 hours of nutrition education, according to the University of Arizona.

Now 15 years into her career as a family physician, Dr. Neison says nutrition is a huge part of her practice. She spends time working to bust myths about nutrition for her patients – including that healthy food is boring and bland, that making it is time consuming, and that healthy food is expensive. She also spends time teaching aspects of culinary medicine to her colleagues – many of whom are well into their careers – so they can better serve their patients.

It’s worth it to spend time learning about nutrition, she said, whether that’s as a medical student in a culinary medicine program or a practicing physician taking additional courses.

Nutrition education in medical school hasn’t been a priority, she said, maybe because there is so much to learn, or maybe because there is no money to be made in prevention.

“If doctors learn it, they are able to better guide patients,” she said.

Dr. Marvasti and his team are set to build out the existing program to develop additional resources for medically underserved and rural communities in Arizona, according to a statement from the university. These plans will be funded by a $750,000 grant from Novo Nordisk.

“We’re going to develop an open education curriculum to share, so it’s open access to everyone,” said Dr. Marvasti, who is also director of Public Health, Prevention and Health Promotion and an associate professor at the university. “It can be adaptable at the undergraduate, graduate, and postgraduate level.”

Dr. Marvasti and his colleagues at the University of Arizona aren’t alone. In fact, culinary medicine programs are sprouting some serious legs.
 

Culinary medicine programs catch on

Jaclyn Albin, MD, CCMS, an associate professor in the departments of internal medicine and pediatrics at UT Southwestern Medical Center, Dallas, conducted a scoping review of the literature on culinary medicine programs for medical students.* Her purpose was to learn how the programs were structured and how they assessed student knowledge and attitudes regarding nutrition counseling for patients.

Dr. Albin and her colleagues performed an initial literature search between June 1 and Aug. 1, 2020, of papers published between Jan. 1, 2012, and Aug. 1, 2020 – excluding some newer programs such as the one at the University of Arizona. The results of their research were published in Academic Medicine.

Ultimately, the authors identified and examined 34 programs offering medical student–focused culinary medicine courses.

Program instructors typically included a team of physicians, dietitians, chefs, and other professionals, the study found.

Most program participants exclusively taught medical students, though the training years of participants varied among programs, and they included first-, second-, third-, and fourth-year students. Some programs allowed students from outside their respective medical school to participate in the trainings.

As for the formats of the program, most included cohorts of 10-20 students attending multiple 2- to 3-hour sessions over the course of several months. The University of Alabama at Birmingham offers one of the longest courses, which spans 4-5 months, according to the paper. In contrast, the University of Rochester (N.Y.) program offers only a 1-day lab divided into four sessions, with each session lasting about 2 hours.

The culinary medicine programs’ course sessions tended to include a 10- to 30-minute didactic session involving videos, research articles, culinary theories, and other lectures, a 60- to 90-minute hands-on cooking session, and a 30-minute discussion around nutrition, culture, and patient care.

Most programs used pre- and post-program surveys to evaluate outcomes, though results varied between programs, according to the study. While each program evaluation had different metrics, the surveys generally revealed students felt more confident discussing dietary interventions with patients and in their own cooking skills following completion.
 

Course correction

Most of those programs are unfunded or minimally funded, Dr. Albin said.

Her own program, which is immensely popular with medical students, is one she teaches on a volunteer basis.

“I do this for free, in the evenings, because I believe in it,” she said.

Medical school education real estate is limited, so convincing medical schools to add something to the curriculum is difficult, Dr. Albin noted.

But it’s worth it, she said, because nutrition is the underpinning of so many diseases.

“Food is the top risk factor for early death in the U.S.,” Dr. Albin said. “I like to say that five times in a row. People have not digested it.”

During her culinary medicine courses, she also asks her medical students: “Who is comfortable in the kitchen?” Some sheepishly raise their hands, she said. Some don’t. Many don’t know anything about cooking.

Then she teaches students about healthy food and how to make it. As part of her program, medical students are given a pantry starter kit with olive oil and a variety of spices to take home and use.

Some recipes Dr. Albin teaches includes mango chili shrimp salad with lime vinaigrette, eggplant sliders, yellow vegetable curry, and strawberry banana chia pudding.

“If you figure out how to do it for your own busy, everyday life, you are now empowered to tell someone else about it,” she said.
 

A dietitian’s involvement

Milette Siler, RD, LD, CCMS, works with Dr. Albin to educate medical students and patients about food as medicine. A significant chunk of her job involves teaching future doctors what dietitians do.

When the class starts, many students don’t know two of the five basic things dietitians do, Ms. Siler said. By the end of the class, all students know what a dietitian does.

That’s important as students go on to become doctors.

“For us to remove barriers to care, we have to acknowledge most patients’ entry into health care is their physician,” she said. “The dietitian is often a referral. Doctors need to know enough to do no harm.”

Clinicians are often siloed, she said, and the key to better serving patients is partnership, transparency, and relationships. “I think everybody is at a point where everyone is saying what we’re doing isn’t working,” she said. “The American public deserves better, physicians deserve better, and clinicians deserve better.”
 

Popular with students

While the old guard has been slow to embrace the shift, her students have helped drive the growth of the culinary medicine field, Dr. Albin said.

“They are not settling for the inadequacy that somehow the rest of us did,” she continued. “I’m so hopeful for the future of the health system. We have a generation of people who will not stand for neglecting the most vital elements.”

Lyndon Bui, a second-year medical student at the University of Arizona, Phoenix, is an example of one of these people.

As a member of a culinary medicine interest group on campus, he said, he has learned a lot about the importance of diet for long-term health. This has given him confidence to talk about food and nutrition.

His group does cooking demos at the Phoenix Farmers Market using food from various local vendors. They usually make a salad from local greens and cook seasonal veggies in a stir fry, he said.

They’ve previously made salad with microgreens – young seedlings of edible vegetables and herbs – and pomegranate seeds with a honey mustard vinaigrette, eggplant or cucumber, and hummus on pita bread, as well as almond butter and honey sandwiches, according to the university.

The group also talks with people in the community, answers questions, and learns about community needs.

Mr. Bui’s participation in this group has helped him cultivate a passion for community outreach that he wants to incorporate into his career.

“I feel like I have the knowledge to provide better advice to patients,” he said. “Knowing all these things about food, I feel more comfortable talking about it and more inclined to refer to a dietitian when maybe I wouldn’t have before.”
 

Family physician applauds culinary medicine programs

When Angie Neison, MD, CCMS, went to medical school, she was surprised there wasn’t more education on nutrition.

In fact, on average, physicians receive less than 20 hours of nutrition education, according to the University of Arizona.

Now 15 years into her career as a family physician, Dr. Neison says nutrition is a huge part of her practice. She spends time working to bust myths about nutrition for her patients – including that healthy food is boring and bland, that making it is time consuming, and that healthy food is expensive. She also spends time teaching aspects of culinary medicine to her colleagues – many of whom are well into their careers – so they can better serve their patients.

It’s worth it to spend time learning about nutrition, she said, whether that’s as a medical student in a culinary medicine program or a practicing physician taking additional courses.

Nutrition education in medical school hasn’t been a priority, she said, maybe because there is so much to learn, or maybe because there is no money to be made in prevention.

“If doctors learn it, they are able to better guide patients,” she said.

Babies born vaginally have a different microbiome to those born by Caesarean section and have heightened responses to childhood vaccinations, according to a new study heralded as “interesting and important” by experts.

The microbiome is known to play a role in immune responses to vaccination. However, the relationship between early-life effects on intestinal microbiota composition and subsequent childhood vaccine responses had remained poorly understood. In the new study, “the findings suggest that vaginal birthing resulted in a microbiota composition associated with an increase in a specific type of antibody response to two routine childhood vaccines in healthy babies, compared with Caesarean section,” the authors said.

Researchers from the University of Edinburgh, with colleagues at Spaarne Hospital and University Medical Centre in Utrecht, and the National Institute for Public Health and the Environment in The Netherlands, tracked the development of the gut microbiome in a cohort of 120 healthy, full-term infants and assessed their antibody levels following two common childhood vaccinations.

The study, published in Nature Communications, found “a clear relationship between microbes in the gut of those babies and levels of antibodies.” Not only was vaginal birth associated with increased levels of Bifidobacterium and Escherichia coli in the gut microbiome in the first months of life but also with higher IgG antibody responses against both pneumococcal and meningococcal vaccines.
 

Antibody responses doubled after vaginal birth

The babies were given pneumococcal and meningococcal vaccinations at 8 and 12 weeks, and saliva was collected at follow-up visits at ages 12 and 18 months for antibody measurement. In the 101 babies tested for pneumococcal antibodies, the researchers found that antibody levels were twice as high among babies delivered naturally, compared with those delivered by C-section. High levels of two gut bacteria in particular – Bifidobacterium and E. coli – were associated with high antibody responses to the pneumococcal vaccine, showing that the microbiome mediated the link between mode of delivery and pneumococcal vaccine responses.

In 66 babies tested for anti-meningococcal antibodies, antibodies were 1.7 times higher for vaginally-born babies than those delivered via C-section, and high antibody levels were particularly associated with high levels of E. coli in the babies’ microbiome.

The results were also influenced by breast-feeding, which even among children born vaginally was linked with 3.5 times higher pneumococcal antibody levels, compared with those of formula-fed children. In contrast, levels of antibodies against meningococcus were unaffected by breast-feeding status.
 

Microbiome ‘sets level of infection protection’

The team said: “The baby acquires Bifidobacterium and E. coli bacteria through natural birth, and human milk is needed to provide the sugars for these bacteria to thrive on.” They explained: “The gut microbiome is seeded at birth, developing rapidly over the first few months of life, and is influenced mostly by delivery mode, breast-feeding, and antibiotic use.” The babies’ microbiome in early life contributes the immune system’s response to vaccines, they said, “and sets the level of protection against certain infections in childhood.”

Study lead Professor Debby Bogaert, chair of pediatric medicine at the University of Edinburgh, said: “I think it is especially interesting that we identified several beneficial microbes to be the link between mode of delivery and vaccine responses. In the future, we may be able to supplement those bacteria to children born by C-section shortly after birth through – for example, mother-to-baby ‘fecal transplants’ or the use of specifically designed probiotics.”

First author Dr. Emma de Koff, a microbiology trainee at the Amsterdam University Medical Center, said: “We expected to find a link between the gut microbiome and the babies’ vaccine responses, however we never thought to find the strongest effects in the first weeks of life.”

The findings “could help to inform conversations about C-sections between expectant mothers and their doctors,” commented the researchers, who said that they could also “shape the design of more tailored vaccination programs.” For example, in the future, vaccination schedules could be adjusted based on the method of delivery or analysis of the baby’s microbiome.
 

Potential to rectify immune system after Caesarean

Responding to the study, Professor Neil Mabbott, personal chair in immunopathology at the Roslin Institute of the University of Edinburgh, told the Science Media Centre: “This is a very interesting and important study. The authors show that infants delivered by a vaginal birth had higher responses to the two different types of vaccines against bacterial diseases, and this was associated with higher abundances of the potentially beneficial bacteria known as Bifidobacterium and E. coli in their intestines.”

He added: “This study raises the possibility that it may be possible to treat infants, especially Caesarean-delivered infants, with a bacterial supplement, or even a product produced by these beneficial bacteria, to help improve their immune systems, enhance their responses to certain vaccines and reduce their susceptibility to infections.”

The study raises important questions, he said, including whether the increased antibody levels from pneumococcal and meningococcal vaccinations following vaginal birth also leads to increased protection of the infants against infection or serious disease. 

Sheena Cruickshank, immunologist and professor in biomedical sciences at the University of Manchester, England, commented: “It is now well established that the microbiome is important in immune development. In turn the mode of delivery and initial method of feeding is important in how the microbiome is first seeded in the baby.”

“However, other factors such as exposure to antibiotics and subsequent diet also play a role in how it then develops, making understanding the way the microbiome develops and changes quite complex. Microbes works as communities, and it can be difficult to determine whether changes in single species are important functionally. Breast milk also plays an important role in protecting the baby via transfer of maternal immunoglobulins, which will wane over a period of 6-12 months in the baby – thus ascertaining whether it’s the baby’s Ig is challenging.

“Given the complexity of the multitude of interactions, it is important that this is accounted for, and group sizes are large enough to ensure data is robust. Whilst this is an interesting study that adds to our knowledge of how the microbiome develops and the possible implications for immune development, it is still very preliminary, and the small group sizes warrant a need for further studies to verify this in larger groups.”

She added: “We will need to understand whether possible impacts of maternal delivery and feeding on immune development or vaccine responses can be restored by, for example, manipulating the microbiome.”

Professor Kim Barrett, vice dean for research at the University of California, Davis School of Medicine, said that, while further research was needed to uncover if and how manipulation of the human microbiome following C-section births might improve vaccine efficacy, “the work should at least lead to prompt additional consideration about an unintended consequence of the ever-increasing use of C-sections that may not be medically-necessary.”

Dr. Marie Lewis, researcher in gut microbiota at the University of Reading, England, said: “We have known for quite some time that the mode of delivery is incredibly important when it comes to the type of bacteria which colonize our guts. We also know that our gut bacteria in early life drive the development of our immune system, and natural births are linked with reduced risks of developing inflammatory conditions, such as asthma. It is therefore perhaps not really surprising that mode of delivery is also linked to responses to vaccinations.”

“The really interesting part here is the extent to which our gut microbiotas are accessible and changeable, and this important work could pave the way for administration of probiotics and prebiotics to improve vaccine responses in Caesarean-born children.”
 

‘Tantalizing data’

Dr. Chrissie Jones, associate professor of pediatric infectious diseases at the University of Southampton, and Southampton UK and education lead for the British Paediatric Allergy, Immunity, and Infection Group, said: “The link between method of delivery of the infant and the bacteria that live in the gut of the young infant has previously been shown. What is really interesting about this study is that, for the first time, the link between method of delivery (vaginal delivery vs. C-section), differences in bacterial communities of the gut, and differences in responses to vaccines is shown.”

“This study may give us fresh insights into the differences that we see in the amount of protective antibodies made after infant vaccination. It also gives us clues as to ways that we might be able to level the playing field for infants in the future – for instance, giving babies a safe cocktail of ‘friendly bacteria’ as a probiotic, or an additional dose of vaccine.”

“This study is the first step – it shows us a link or association but does not prove cause and effect that differences in the way babies are born alters how the immune system responds to vaccines. To prove this link we will need larger studies, but it is tantalizing data.”

The research was funded by Scotland’s Chief Scientist Office and the Netherlands Organisation for Scientific Research. DB received funding from OM pharma and Sanofi. All of the authors declared no other conflicts of interest.
