Not The Onion: Cow Potty Training

AP: No bull: Scientists potty train cows to use ‘MooLoo’

An excerpt:

Turns out cows can be potty trained as easily as toddlers… 11 out of 16 cows learned to use the “MooLoo” when they had to go…And it took only 15 days to train the young calves.

[Results were] published Monday in the journal Current Biology...Massive amounts of urine waste is a serious environmental issue,…A single cow can produce about 8 gallons (30 liters) of urine a day… toilet training animals makes it easier to manage waste products and reduce greenhouse gas emissions

The researchers mimicked a toddler’s training, putting the cows in the special pen, waiting until they urinated and then giving them a reward: a sweet liquid of mostly molasses… If the cows urinated outside the MooLoo after the initial training, they got a squirt of cold water…

The biggest environmental problem for livestock, though, is the heat-trapping gas methane they emit in belches and flatulence, a significant source of global warming. The cows can’t be trained not to belch or fart, Matthews said: “They would blow up.”

Celiac Disease and Lack of Response to Hepatitis B Immunization

A Aneja et al. JPGN Reports February 2021 – Volume 2 – Issue 1 – p e046: Open Access: Clinical Characteristics of Children With Celiac Disease Not Responding to Hepatitis B Vaccination in India

Methods: The study population from consisted of 3 groups—50 newly diagnosed CD children (group 1), 50 previously diagnosed CD children who were on gluten free diet (GFD) >3 months (group 2), and 100 age and gender matched healthy controls (group 3).

Key findings:

  • Positive anti-HBs response was found in 46% in newly diagnosed CD children, 60% in CD children on GFD, and 83% in healthy controls (P < 0.001)
  • Ongoing gluten intake has significant impact on protective immune response to Hepatitis B vaccine
  • 44 out of 45 (97.77%) nonresponders from CD group seroconverted after a single booster dose

My take: Check Hep B immune response in patients with celiac disease.

Inflammatory Bowel Diseases, izab207https://doi.org/10.1093/ibd/izab207 Open Access: Antibody Responses to SARS-CoV-2 After Infection or Vaccination in Children and Young Adults With Inflammatory Bowel Disease This article showed that there was a “lower and less durable SARS-CoV-2 S-RBD IgG response to natural infection in IBD patients receiving biologics [which] puts them at risk of reinfection. The robust response to immunization is likely protective.” Also, “hospitalized pediatric patients with PCR documented SARS-CoV-2 infection, S-RBD IgG antibody levels were significantly lower in the IBD cohort and by 6 months post infection most patients lacked neutralizing antibody.” This study provides a strong rationale for vaccination, especially in our IBD patients.

AGA Clinical Practice: Colorectal Dysplasia in Inflammatory Bowel Diseases

SK Murthy et al. Gastroenterol 2021: DOI:https://doi.org/10.1053/j.gastro.2021.05.063. Full Text: AGA Clinical Practice Update on Endoscopic Surveillance and Management of Colorectal Dysplasia in Inflammatory Bowel Diseases: Expert Review

Some of the recommendations:

Best Practice Advice 1: Precancerous colorectal lesions in inflammatory bowel disease should be described as either polypoid (≥2.5 mm tall), nonpolypoid (<2.5 mm), or invisible (detected on nontargeted biopsy), using a modified Paris Classification. The older terms dysplasia-associated lesion or massadenoma-like mass, and flat dysplasia (when referring to dysplasia detected in nontargeted biopsies) should be abandoned.

Best Practice Advice 3: Initial colonoscopy screening for dysplasia should be performed at 8–10 years after disease diagnosis in all people with colonic inflammatory bowel disease, and immediately on diagnosis of primary sclerosing cholangitis. Staging biopsies should be taken from multiple colonic segments to assess histologic disease activity and extent and to help guide future surveillance intervals.

Best Practice Advice 8: Extensive nontargeted biopsies (roughly 4 adequately spaced biopsies every 10 cm) should be taken from flat colorectal mucosa in areas previously affected by colitis when white light endoscopy is used without dye spray chromoendoscopy or virtual chromoendoscopy. Additional biopsies should be taken from areas of prior dysplasia or poor mucosal visibility. Nontargeted biopsies are not routinely required if dye spray chromoendoscopy or virtual chromoendoscopy is performed using a high-defintion endoscope, but should be considered if there is a history of dysplasia or primary sclerosing cholangitis.

Improving Surveillance and Screening Colonoscopy

R Keswani et al. Gastroenterol 2021; 161: 701-711. Full text (open access) AGA Clinical Practice Update on Strategies to Improve Quality of Screening and Surveillance Colonoscopy: Expert Review

While these guidelines are geared towards adult gastroenterologists for colorectal cancer screening, some advice is universally applicable

  • tracking quality metrics: good prep, cecal intubation rate, and adverse events
  • good bowel preparation instructions
  • detailed endoscopy reports
  • appropriate followup: All patients with advanced adenomas should have repeat colonoscopy in 3 years. Average-risk patients with normal screening colonoscopies or those with only small distal hyperplastic polyps should not undergo repeat examinations before 10 years

Vedolizumab Exposure in Newborns

M Juulsgard et al. AP&T 2021: https://doi.org/10.1111/apt.16593. Vedolizumab clearance in neonates, susceptibility to infections and developmental milestones: a prospective multicentre population-based cohort study

Key findings:

  • In 50 vedolizumab-exposed pregnancies, we observed 43 (86%) live births, seven (14%) miscarriages, no congenital malformations and low risk of adverse pregnancy outcomes
  • The mean time to vedolizumab clearance in infants was 3.8 months (95% CI, 3.1-4.4)
  • No infant had detectable levels of vedolizumab at 6 months of age
  • Developmental milestones at 12 months were normal or above average
  • Neither vedolizumab exposure in the third trimester (RR 0.54, 95% CI, 0.28-1.03) nor combination therapy with thiopurines (RR 1.29, 95% CI, 0.60-2.77) seemed to increase the risk of infections in the offspring

My take: Given the good safety profile of vedolizumab, this small study provides additional reassurance regarding use of vedolizumab during pregnancy.

ImproveCareNow Work in Progress

P Kandavel et al. JPGN 2021; 73: 345-351. Reduced Systemic Corticosteroid Use among Pediatric Patients With Inflammatory Bowel Disease in a Large Learning Health System

In this study of 27,321 patients enrolled in the ImproveCareNow (ICN) learning health system, key findings:

  • Corticosteroid use decreased from 28% (2007) to 12% (2018)
  • Black patients received corticosteroids more commonly than white patients. This disparity improved as corticosteroid use decreased in both groups
  • Anti-tumor necrosis factor-alpha medication use <120 days after diagnosis was associated with a reduction in corticosteroid use
  • As corticosteroid use decreased, steroid-sparing therapy use increased and height and weight z scores improved, particularly among children with Crohn disease
  • 27 centers (31%) had a significant reduction in steroid use, 5 (6%) had a significant increase, and 45 (52%) had variability in steroid use. 9 centers (11%) had <2 years of data.

My take: These findings are expected but nice to see. Patients in the ICN are using less steroids and growing better. Given the variation in care among centers, there is more work needed.

How Good is Your Prep?

There are a lot of articles that have been published regarding bowel preparations prior to colonoscopy, especially in adults. One of the key advances has been split-prep dosing, which is not utilized much in the pediatric age group.

Nevertheless, a recent pediatric study (S Kumar et al. JPGN 2021; 73: 325-328. Inadequate Bowel Preparation in Pediatric Colonoscopy—Prospective Study of Potential Causes) shows that inadequate bowel preparation in their prospective cohort (n=334) was less prevalent than that noted from typical adult data. Their bowel preparation assessmetn was based on Boston Bowel Preparation Scale (BBPS).

Key finding: Inadequate bowel preparation (IBP) was noted in 12.8% (41/321); there were no age, gender, obesity, race, or insurance type associated with IBP. (IBP was defined by BBPS <5)

Their preparation instructions:

  • If <25 kg, “119 g of PEG 3350 mixed in 32 oz of sport drink” and then “additional 32 oz of a sports drink without PEG 3350”
  • If 26-49 kg, “238 g of PEG 3350 mixed with 64 ounces of fluids” and then “additional 64 oz of a sports drink without PEG 3350”
  • If >50 kg, “238 g of PEG 3350 mixed with 64 ounces of fluids” and then “64 ounces of a sports drink and four bisacodyl tablets”

My take: If you are seeing a high rate of IBP, the prep instructions in this study could be replicated (given their good results), split preps could be given for teens, and better instructions (visual aids) could be needed.

CE Brinck et al. JPGN 2021; 73: 306-313. Regional Gastrointestinal Motility in Healthy Children

This article is a proof-of-concept study describing the use of “3D-Transit system” to provide information on regional gastrointestinal motility. This study examined 20 healthy children who ingested a electromagnetic capsule (21.5 mm x 8.3 mm) which was tracked by a vest detector.

Key findings:

  • Median whole gut transit time was 33.6 (range 10.7–80.5) hours
  • Median gastric emptying time was 1.9 (range 0.1–22.1) hours
  • Median small intestinal transit time was 4.9 (range 1.1–15.1) hours
  • Median colonic transit time was 26.4 (range 6.8–74.5) hours.

Table 1 provides the median values along with 5%, and 95% values.

Limitations: small sample size, and this system requires manual analysis. In addition, the capsule itself due to its size and viscosity may influence transit times.

My take: This capsule motility study suggests that whole GI tract transit averages 34 hrs. This system could provide some objective data on motility in children and it is probably more useful than the corn test (though not as tasty); however, I doubt its use will be more helpful than Sitz markers for the majority.

Updated ESPGHAN Percutaneous Endoscopic Gastrostomy Position Paper

M Homan et al. JPGN 2021; 73: 415-426. Open Access: Percutaneous Endoscopic Gastrostomy in Children: An Update to the ESPGHAN Position Paper

A couple of interesting recommendations in this updated position paper on the use of percutaneous endoscopic gastrostomy (PEG) include the following:

  • Feeding can be initiated as early as 3 hours post-procedure in a stable child with no complications.
  • Iso-osmolar feeds of the standard polymeric formula are the best type of food to start with after the PEG insertion” and ” bolus feeding is more physiological and should be the first choice… in some children, small boluses during the day could be combined with the overnight continuous feeding via enteral pump.”
  • Replacing the initial tube with a gastric balloon/button should be recommended to the families/children who will need long term enteral nutrition to improve quality of life.”
  • Gastric balloons should be replaced every 6 months, but non-balloon PEGs can be replaced annually.”

The full article provides a rationale/nuance for these recommendations. Use of feeds starting at 3 hrs post-op has been found to be safe. And, there is no evidence available that suggests routine use of a clear fluid test or dilute or hypotonic feed after the procedure. In fact, it has been suggested that these measures delay the time to full enteral intake and prolong hospital stay.

With regard to balloon button Gtube changes, the authors note that while manufacturers recommend changing every 3 months, “in the majority, these are safe to replace less frequently.”

The authors clearly favor low-profile buttons and state that changing to them earlier after initial Gtube placement (after 1 month) under general anesthesia should be safe (if no issues with healing like diabetes, and systemic corticosteroids); “however, the physician should give the parents/child the possibility of choice whether to perform the replacement or not.” Also, “the primary device can stay in place for one year or even more. In a German study, 85% of parents answered that the GB is advantageous over primary gastrostomy tube due to mobility, patient comfort at physiotherapy, swimming or night-time sleep, and higher parent satisfaction.”

My take: This article provides a good summary of PEG indications/contraindications, complications, and advise for clinicians
