We all Scream for Sunscreen!

Spring is finally here and summer is around the corner! Today's wellness POTD is about a skincare and healthcare product that is near and dear to my heart: SUNSCREEN! 

If you guys don't know, I carry sunscreen with me everywhere, and even after overnight shifts before walking outside, I put on sunscreen. Of course with all things there are nuances, like do I really need sunscreen at 7am in December? Probably not, since the UV index is low, but it helps me form a habit so that on those sunny days I never forget. Also, picking the right sunscreen for daily use that is moisturizing, lightweight, and that you enjoy using is key to adherence. 

So for all you sunscreen-naive people out there, here is an overview of sunscreen and my favorite ones!

Characteristics of Sunscreen

• Chemical, mineral, or hybrid filters

  • Sunscreens that use hybrid or only chemical filters usually have a lighter texture

  • Mineral sunscreens are heavier and more likely toe leave a chalky residue or white cast

• Clear or quickly absorbing formulas that don’t leave a white cast, even on deeper skin tones

• Gentle and hypoallergenic formulas that contain fragrance-free and soothing  ingredients

• Hydrating formulas that contain humectants like hyaluronic acid without feeling heavy or greasy

• Makeup-friendly formulas that layers well under foundation/BB cream with no pilling or excessive shine

• High SPF, broad-spectrum – ideally SPF 30–50+ with strong UVA protection (PA++++ or “broad spectrum” on US labels)

Korean brand sunscreens are my favorite because of their cosmetically elegant formulations. Here in the US, since sunscreens are a regulated OTC drug by the FDA (which only approves a limited number of UV filters, last updated in 1999) we are wayyy behind South Korea and the EU. The modern “next-gen” filters like Tinosorb S/M and Uvinul A Plus, results in lighter sunscreen formulas. Unfortunately, the 2022 Modernization of Cosmetics Regulation Act (MoCRA), although not directly targeting sunscreens, increased FDA oversight and prompted Korean brands to reevaluate their US distribution. As a result, popular brands like Round Lab, Beauty of Joseon, and Skin1004 reformulated or withdrew their popular SPF50+ products from US channels in 2023–2024. Many US versions now use only FDA-approved filters that often have thicker textures with lower SPF ratings, while others now sell only through international retailers.

Neonatal Code Cart

The neonatal code cart contains more specialized equipment for resuscitation of neonates, typically <28 days old. 

Having to resuscitate such a tiny baby is a daunting task, and fortunately very rare, but unfortunate as we are not well-versed with all the moving parts. In these cases, just like with the Broselow cart, familiarizing ourselves with the contents of the neonatal code cart will be essential to a proper resuscitation.

Setting the scene...

We get a call that a mother just delivered in the ambulance and the baby is not responsive: not crying, not moving; ETA 5 minutes.

First: ask a PCT to locate the baby warmer and get it to resus 51 along with a bunch of dry towels.

Head to resus 51 and clear all the obstacles to the neonatal code cart and take note of several things outside the code cart that are important:

We open the neonatal airway box which sits on top of the neonatal code cart and hook up the infant ambu bag, have suction ready, and lay out the intubation supplies.

Next, we open the first drawer which is the medications:

As the nurses are opening the rest of the drawers, EMS rolls in with mother and baby, another team is taking care of mom, and the baby is handed over to us into the baby warmer and we are using the abundance of dry towels to dry off the baby and stimulate, stimulate, stimulate!

EMS reports: Baby is mother's 3rd baby, ex-39 weeks female, no known complications during pregnancy as she had no prenatal care, baby is 4kg. Vitals en route: HR 70bpm, O2 sat 85%, BP 65/35, BGM 80

Meanwhile, the nurses are hooking up the baby to the monitor, getting vitals, and attempting to start an IV.

Drawers 2-4 has IV materials, fluids, EKG leads, suction, etc:

It has been 2 minutes since the baby arrived in the ER and the HR is 75 bpm and the baby is not breathing spontaneously or crying. You've already dried, stimulated, suctioned, and have been using the infant ambu bag to give some positive pressure support with good bilateral chest rise and positive breath sounds bilaterally and O2 saturation is 95%.

Someone taking care of the mother comes in and reports that the mother had taken several tabs of morphine for the painful contractions that her father had left over for back pain.

Patient is 4kg, and so 0.1mg/kg is 0.4mg, 0.4mL of Naloxone is given to the patient via IV (can be given IM or through an ETT).

Patient starts breathing spontaneously with O2 sat 100%, heart rate improves to 90, but BP is still 65/35. You ask the nurse to start IV fluids but after the Narcan was administered the IV stopped working and they are having difficulty obtaining a 2nd IV for access.

You decide to do an umbilical vein catheterization and look to the last drawer:

Umbilical vein catheterization:

1. Sterile prep of the umbilical area and drape

2. Securely tie a cord tie around the base of the umbilical stump

3. Cut cord horizontally at the distal end of the stump to expose vessels about 1-2 cm distal to the cord tie

4. Identify the umbilical vein (thin-walled, larger, single vessel vs. two thicker arteries)

5. Dilate gently with forceps and insert catheter (3.5 Fr for neonates <3.5kg, 5Fr for neonates >3.5kg)

6. Aspirate for blood return, then advance to appropriate depth

   • For a full term infant insert to about 4-5cm (about 2cm further than where you get blood return) for emergency access and approximately 10-12cm for long term access (based on umbilicus to shoulder measurement).

7. Flush with saline to ensure patency

8. Secure catheter with umbilical tape or suture

9. Verify position with Chest/abdominal X-ray to confirm tip location at inferior vena cava–right atrial junction, typically at T8–T9

10. Adjust as needed based on imaging

Patient received IV fluids and blood pressure improved to 80/45, vitals otherwise stable. Patient admitted to the NICU.

Takeaways:

• All the equipment and medications used for resuscitations are included in the neonatal code cart. 

  • Streamlines processes as we do not need to waste time and search for the proper equipment when time is so important during a resuscitation.

• Familiarity with the equipment and medications in the code cart helps us prepare for those rare and unexpected resuscitations

• Umbilical vein catheterization can be done for patients who have poor peripheral access, requires further resuscitative medications, or for central venous monitoring.

Asthma Management from the ED

We treat a lot of patients with asthma in the ER, and a lot of times our patients have trouble following up with their PCP, establishing care with a new PCP, or even getting insurance. Usually, we discharge patients with just a short-acting beta-agonist (SABA) inhaler like albuterol and possibly a separate inhaled corticosteroid (ICS), but maybe we should consider prescribing combined ICS and long-acting beta-agonist (LABA) inhaler.

Guidelines and Evidence

• Global Initiative for Asthma (GINA) recommends symptom-driven treatment or daily ICS-containing inhalers to reduce severe exacerbation risks

• Formoterol is a LABA with a rapid onset, suitable for both maintenance and rescue therapy

• Multiple studies were done with low dose ICS and combination therapies
  

  • Low-dose ICS in mild asthma reduces severe exacerbations by ~50%, improves symptom control, and enhances quality of life (Reddel 2019 or SYGMA-2)

  • Fixed-dose LABA/ICS used as needed is as effective as regular ICS, reducing hospital visits and daily ICS exposure without increasing adverse events (Crossingham 2021)

  • Budesonide/formoterol improves oxygen saturation, peak expiratory flow rate, and reduces respiratory rates post-treatment (Chew 2012)

Caveat: Noninferiority Study Design

• SYGMA-2 was initially designed as a superiority trial but was later reclassified as a noninferiority trial without clear justification or protocol amendments

• The trial set a noninferiority margin of 20% (rate ratio of 1.2), meaning the as-needed ICS-formoterol regimen could be up to 20% less effective than the standard therapy and still be considered noninferior. The 95% confidence interval for the primary outcome was 0.97 to 1.16, approaching the noninferiority threshold, suggesting a potential risk of inferiority in broader clinical practice.

• Noninferiority does not mean similarity, the trial's design and outcomes need to be carefully interpreted especially when informing global guidelines

Conflict of Interest Concerns

• While investigators collected the SYGMA-2 trial data, the analysis was conducted by employees of the sponsoring pharmaceutical company

• All but two authors disclosed receiving support from the sponsor. Notably, one author served on the Board and Science Committee of GINA. Although these conflicts were declared, the article does not specify how they were addressed or mitigated

• Close ties between study authors and the sponsor raise questions about the impartiality of the evidence informing the GINA guidelines

• The study outcomes and guideline recommendations that favor the sponsor's product is now called into question

Benefits of Discharging with ICS-LABA (e.g., Symbicort)

• Formoterol’s rapid onset makes it suitable as a rescue medication even though it is a LABA

• Improves adherence by simplifying to one inhaler for both rescue and maintenance

• Suggested Prescription: Budesonide/formoterol 80/4.5 μg per puff. Maintenance: 1-2 puffs once or twice daily OR Rescue: 1-2 puffs every 2-4 hours as needed for symptoms

  • Of note, Symbicort is NOT FDA approved as a rescue inhaler

Cost of Symbicort Without Insurance

• The out-of-pocket cost for Symbicort can be substantial:

  • Brand-name Symbicort (80/4.5 mcg): Approximately $344.41 for a 30-day supply.

  • Generic versions: Around $232.12 for the same dosage.

  • Authorized generic (Breyna): Approximately $206.71.

• Some pharmacies offer Symbicort for as low as $97.09 with a GoodRx coupon

• As of June 1, 2024, AstraZeneca has capped the out-of-pocket cost of Symbicort at $35 per month for both insured and uninsured patients (with possible limitations)

Prior Authorizations and Alternative

• Obtaining prior authorization (PA) for medications like Symbicort from the ED is not feasible due to the complex process:

  • Verify the patient's insurance coverage and determine if Symbicort requires prior authorization

  • Access and fill out the required PA forms found on the insurance provider's website

  • Send the completed forms to the insurance company via their preferred method (fax, online portal, etc.)

  • Follow the status of the PA request and provide any additional information if requested

• The other way is to refer your patients and their family members to this site:

  • https://www.azpatientsupport.com/

  • They can obtain a card that caps the cost of Symbicort at 35$ with a valid prescription

Takeaways

• There's evidence supporting the use of ICS-formoterol as both maintenance and rescue therapy, however due to COI and dubious study design the recommendations are called into question

• For patients discharged from the ED with mild to moderate asthma exacerbations, consider prescribing combined ICS/LABA instead of separate albuterol and ICS after shared decision making with patient and family

• Educate your patients on the capped cost of Symbicort and possibly send them with a prescription and a savings card
