    #167 - How Is Chronic Rhinosinusitis Without Nasal Polyps Diagnosed and Treated?

    Chronic rhinosinusitis without nasal polyps (CRSsNP) is the type that makes up most chronic sinusitis cases. It's often mistaken for allergies, a lingering cold, or migraines, which can delay a proper diagnosis for years. Dr. Gupta and Kortney sit down with Dr. Anju Peters, an allergist at Northwestern University's Feinberg School of Medicine, to unpack how this condition is actually diagnosed, why it can take patients years to get an answer, and which treatments have real evidence behind them. What we cover in this episode about chronic sinusitis without nasal polyps Two types of chronic sinusitis. About 75% of chronic sinusitis patients do not have nasal polyps, and about 20 to 25% do, and the treatment path differs depending on which type you have. Getting the right diagnosis. Doctors confirm chronic sinusitis without nasal polyps by combining at least 12 weeks of symptoms with objective proof of inflammation. Ruling out look-alikes. Allergies, colds, and migraines can all cause similar congestion and pressure, so doctors pay close attention to how long symptoms last and whether inflammation is actually confirmed. Building a treatment toolkit. Nasal steroid sprays are the backbone of treatment. When to consider surgery. When sinus surgery becomes the next step in sinus care.

    #166 - How Pregnancy and Your Baby's Gut Microbiome Play a Role in Food Allergy Prevention

    Food allergy prevention is something most families think about once a baby starts eating. But the gut microbiome begins developing before birth, and what happens during pregnancy matters for the development of food allergies. This is a bonus episode from our conversation with Dr. Carina Venter. The clip did not make it into Episode 165, but it was too good not to share. Dr. Payel Gupta and Kortney dig into what Dr. Venter shared about pregnancy, the gut microbiome, and what families can do in that critical first year of life. What we cover in this episode about pregnancy and food allergy prevention How the gut microbiome develops before and after birth. From pregnancy through the first year of life, several key factors shape your baby's gut microbiome, including mode of delivery, breastfeeding, and the introduction of solid foods. What happens if things do not go as planned. A difficult pregnancy, a C-section, or not being able to breastfeed does not mean you have missed your chance to help your baby develop a healthy gut microbiome.  What the research on pregnancy diet actually shows. A look at how maternal diet during pregnancy and breastfeeding may affect a child's risk of allergies. Early introduction and why it matters. Introducing allergenic foods between four and six months of age and keeping them in the diet consistently may reduce the risk of food allergy by ten to thirty percent. What to feed your baby to support a healthy gut. Diversity, whole foods, and sustained exposure to allergens are the key takeaways for families starting solids.

    #165: Gut Microbiome's Role in Food Allergies

    You have probably heard the word "microbiome", but what does it actually mean for someone living with a food allergy? Dr. Carina Venter, a registered dietitian, joins us to break down the gut’s role in food allergies. She explains what the microbiome is, how it connects to the immune system, and what families can realistically do right now to support a healthier gut. What we cover in this episode about gut health and food allergies What the microbiome actually is. Understanding the bacteria living in your gut, why diversity matters, and what happens when that balance gets disrupted. The connection between gut bacteria and food allergy. Research consistently shows that children with food allergies have lower levels of two key bacteria, and that gap may affect how the immune system responds to food. Leaky gut and ultra-processed foods. What leaky gut actually means and research on emulsifiers. Should you be taking probiotics? Which strains have the most research behind them, what to look for on the label, and why diet diversity may matter more than any supplement. Practical steps for families. From a diverse diet to when to use supplements. About our guest, Dr. Carian Venter: https://www.carinaventer.com/ __ This podcast is made in partnership with the Allergy & Asthma Network

    #164 - New Chronic Hives Guidelines: A Look at What's Changing

    In this journal club episode, we break down the draft of the Chronic Urticaria Guidelines: 2026 AAAAI/ACAAI Joint Task Force (JTF) on Practice Parameters GRADE- and Institute of Medicine-based recommendations. We explain what counts as chronic hives, why the guideline leans on second-generation non-drowsy antihistamines, what to do when those are not enough, and what is new for both adults and kids. At the time of recording, the draft was open for comments; it closed for comments on June 30, 2026. What we cover in our episode about the new chronic hives guidelines What chronic hives are: A plain-language look at the two main types, spontaneous and inducible, plus angioedema (swelling) that can come with them. What a draft guideline is: Why the guideline is still being reviewed, and how comments can help shape it before it is final. What's new for kids: How children fit into the guideline, and why most do well without advanced treatments. The antihistamine shift: Why the guideline favors non-drowsy, second-generation antihistamines and moves away from older, sedating ones. When antihistamines are not enough: If higher-dose antihistamines do not work, the recommended advanced option is to start omalizumab (Xolair) plus two newer additions: dupilumab (Dupixent) and remibrutinib (Rhapsido).

    #161 - BREATHE: The Digital Asthma Management Tool

    Most adults with asthma never receive education about managing their condition, even though it is proven to help with better asthma control. The reason comes down to access. In this episode, we explore a digital platform called BREATHE, built from the ground up to change that. Dr. Payel Gupta and Kortney sit down with the two lead authors behind “Development and Usability of a Digital Asthma Self-management Education Platform: BRinging Exercise, Asthma Assessments, and TeacHing to Everyone (BREATHE)” published in JACI: In Practice, March 2026. De De Gardner and Sheryl Flynn, CEO, talk about how BREATHE was developed, what the app includes, and what the data showed after patients and providers put it to the test. What we cover in this episode about asthma self-management Asthma self-management education and why most adults never receive it. How BREATHE was built using a user-centered design process, shaped by what adults with asthma and healthcare providers said they actually needed. What the BREATHE platform includes: asthma lessons, validated control assessments, and an Asthma Action Plan, all in one app, in English and Spanish. What the usability study found: adults rated the app in the 81st percentile, providers rated the dashboard in the 76th percentile, and 80% considered making a behavior change after just two weeks. Where the program is now and where it is going, including how to access the free Allergy and Asthma Network Virtual Asthma Coaching Program today.
