Is Obamacare Causing Skyrocketing Premiums?

Posted on by

Not yet according to a recent commentary: BD Sommers. NEJM 2016; 375: 201-3. The graph below provides some perspective.  In addition, the author cautions those who have voiced early alarm bells regarding upcoming rates.  He notes the same alarms have been raised in the previous 2 years. Though, he notes, “there are reasons to suspect that marketplace premium growth for 2017 will exceed this year’s levels.  Two of the law’s provisions designed to reduce financial risk to insurers in the new markets expire after 2016 — the risk corridor and reinsurance provisions…the country’s continued emergence from the aftermath of the Great Recession may well spur increasing rates of health care inflation for the general population, as well as for the ACA exchanges”

“Premium growth — even when it does reach into the double-digit range that sparks such substantial media attention — is a policy challenge to be examined and addressed and is also part of the general historical pattern that precedes the ACA.”  Those who argue “the law as a whole should be scrapped ignore the devastating effect that repeal would have on the estimated 20 million Americans who have thus far gained insurance under the law.”

My take (from commentary): “Regardless of what ends up happening this year, it seems likely that next spring will bring renewed claims that the sky is falling — when experience should make clear that it isn’t.”

Intraluminal duodenal diverticulum is a rare duodenal congenital abnormality caused by an anomalous process of recanalization of the primitive foregut. It has a characteristic radiographic appearance on contrast studies, resembling a “windsock web” or “thumb of a glove”

Screen Shot 2016-07-29 at 10.30.28 PM

An upper gastrointestinal (GI) endoscopy was then performed that revealed a 3-cm pedunculated mass in the second part of the duodenum that was biopsied (Figure A), and the patient was referred for an endoscopic ultrasound. A repeat endoscopy before the endoscopic ultrasound revealed a large intraluminal diverticulum that had the appearance of a mass when inverted. Subsequently (Figure B), an upper GI series was performed that showed a large elongated tubular diverticulum arising from the second portion of the duodenum, 2.5 × 12 cm in size, with rapid filling and peristalsis with oral contrast, which extended to the left aspect of the spine when maximally distended

Bedtime in Preschool-Aged Children and Risk for Adolescent Obesity

Posted on by

An upcoming article (Journal of Pediatrics, (DOI: http://dx.doi.org/10.1016/j.jpeds.2016.06.005)shows an association between bedtime and the development of obesity:

Full-text link: Bedtime in Preschool-Aged Children and Risk for Adolescent Obesity

Abstract:

Objective

To determine whether preschool-aged children with earlier bedtimes have a lower risk for adolescent obesity and whether this risk reduction is modified by maternal sensitivity.

Study design

Data from 977 of 1364 participants in the Study of Early Child Care and Youth Development were analyzed. Healthy singleton-births at 10 US sites in 1991 were eligible for enrollment. In 1995-1996, mothers reported their preschool-aged (mean = 4.7 years) child’s typical weekday bedtime, and mother-child interaction was observed to assess maternal sensitivity. At a mean age of 15 years, height and weight were measured and adolescent obesity defined as a sex-specific body-mass-index-for-age ≥95th percentile of the US reference.

Results

One-quarter of preschool-aged children had early bedtimes (8:00 p.m. or earlier), one-half had bedtimes after 8:00 p.m. but by 9:00 p.m., and one-quarter had late bedtimes (after 9:00 p.m.). Children’s bedtimes were similar regardless of maternal sensitivity (P = .2). The prevalence of adolescent obesity was 10%, 16%, and 23%, respectively, across early to late bedtime groups. The multivariable-adjusted relative risk (95% CI) for adolescent obesity was 0.48 (0.29, 0.82) for preschoolers with early bedtimes compared with preschoolers with late bedtimes. This risk was not modified by maternal sensitivity (P = .99).

Conclusions

Preschool-aged children with early weekday bedtimes were one-half as likely as children with late bedtimes to be obese as adolescents. Bedtimes are a modifiable routine that may help to prevent obesity.

My take: Another potential reason to heed Samuel Jackson’s advice: Go the F- to Sleep (early)

How often are acid blockers used in neonates?

Posted on by

A recent study (JL Slaughter et al. J Pediatric 2016l 174: 63-70) shows a high rate of acid blockers in neonatal intensive care units.  This study retrospectively analyzed the Pediatric Health Information System database (PHIS) from 2006-2013.

  • Of 122,0002 infants: 23.8% received either a histamine-2-receptor antagonist (H2RA) or proton pump inhibitor (PPI).
  • 19.0% had received an H2RA
  • 10.5% had received a PPI

My take (borrowed from authors): “despite limited evidence and  increasing safety concerns, H2RAs/PPIs are frequently prescribed to extremely preterm neonates…Our findings support the need for innovative studies.”  Wouldn’t it be nice if there was proof of efficacy in this population?

Preventing Neonatal Hepatitis B Transmission with Tenofovir

Posted on by

A recent study (CQ Pan et al. NEJM 2016; 374: 2324-34) showed that tenofovir administered to mothers starting at 30-32 weeks of gestation lowered the rate of perinatal hepatitis B virus (HBV) acquisition.This was a multi center, open-label, randomized parallel-group design trial.  The maternal tenofovir dose was 300 mg.

Key points:

  • 200 mothers with HBeAg and HBV DNA >200,000 IU/mL in this study
  • 68% achieved an HBV DNA level <200,000 IU/mL (compared with 2% of controls).  Above this threshold has been shown to be associated with increased HBV transmission.
  • 5 of 97 (5%) in the treatment group acquired HBV compared to 18 of 100 in the control group.  However, in the per-protocol analysis which excluded infants born to women who withdrew consent, were lost to follow-up, or discontinued therapy there were 0 cases of transmission (0 of 88).
  • There were no specific safety signals identified in this study.  In the discussion, the authors note that the Antiretroviral Pregnancy Registry which includes data from 4013 women who received tenofovir, the rate of birth defects with TDF was 2.4% compared to the general population rate of 2.7%.

My take: This study provides more evidence that antivirals can prevent perinatal HBV infection.

Intellectual Disability in Pediatric Liver Transplantation

Posted on by

A recent study (A Wightman et al. JPGN 2016; 62: 808-12) describes the prevalence of intellectual disability in a retrospective cohort from 2008-2013. The importance and the discomfort of the topic is referenced in the introduction:

  • “A 2005 survey of pediatric liver transplant programs (n=12) found that 33% of centers reported that cognitive disability was “always or usually” considered in their decision. No pediatric centers, however, considered mild or moderate cognitive disability alone (IQ 35-70) to be a relative or absolute contraindication to transplantation.”
  • The 2005 AASLD guideline states that “children with mental retardation pose significant logistical and ethical challenges” but does not comment on whether this is a contraindication.

This retrospective study of children who underwent an isolated liver transplant from 2008-2013 (n=254).

Key findings:

  • 15% of all first pediatric liver transplantation recipients have intellectual disability
  • Graft function and patient survival were similar among those with and without intellectual disabilities.  Metabolic disease, as the indication for liver transplantation, was the etiology more commonly among children with intellectual disability.

This study had numerous limitations.  Due to these limitations (eg. selection bias, lack of a standardized mechanism of measuring intellectual disability), it is likely that intellectual disability occurs more commonly than in 15% of pediatric liver transplant recipients. In fact, a previous study showed 42% of recipients required special education and 29% had IQ <85 (Cognitive Outcomes after Liver Transplantation | gutsandgrowth).

Related neurocognitive recommendations from the 2014 AASLD Pediatric Liver Transplantation Guidelines:

  • 28. “Neurocognitive testing should be performed in children awaiting LT to identify areas warranting early intervention to minimize later cognitive diffi- culties (2-B).”
  • 75, 76, and 92. LT is contraindicated with Alper’s disease, multiorgan mitochondrial disease, and Niemann-Pick type C.
  • In nearly 40 pages of recommendations, this guideline offers very little guidance on this topic.

“Explain It To Me Like I’m a Six Year Old”

Posted on by

Sometimes when I read an article, I wish it was presented in a much simpler manner.  In the movie “Philadelphia,” the lawyer played by Denzel Washington tells his clients to “explain it to me like I’m a six-year-old.”

A recent clinical report (MI Ardura et al. JPGN 2016; 63: 130-55) probably would have benefitted from this idea to some degree.  This report examines infectious disease issues with regard to patients receiving tumor necrosis factor-α (TNFα) inhibitors.  All in all, it is very thorough and reviews more than 20 infectious agents (bacteria, fungi, mycobacteria, and viral agents).

Table 2 is most helpful.  In this table, the authors recommend that before starting TNF inhibitors:

  • Risk factor screening for Brucella (eg exposure to animals, unpasteurized dairy products), Bartonella (eg exposure to kitten), Listeria (eg dietary history), Salmonella (eg exposure to reptiles), Aspergillus (eg exposure to construction), coccidioidomycosis (exposure to endemic area), Histoplasma (long list of exposures listed in Table 3 includes barns, caves, chicken coops, old buildings), and Hepatitis C virus
  • Direct testing is recommended for Mycobacterium tuberculosis, Hepatitis B virus, HIV (≥ 13 yrs if in hospital or ≥15 years), and Varicella zoster virus

Table 4 lists recommended vaccines.  For live virus vaccines, the authors recommend to avoid unless they can be administered at least 4 weeks prior to immunosuppressive therapy.

Other useful information:

  • “Granulomatous infections caused by bacteria, mycobacteria, and fungi are the most frequently  described infections in patients receiving anti-TNFα therapies.”
  • Infection rates of 239/100,000 reported with infliximab between 1998-2002.
  • More than 70% of these infections occurred within 3 to 6 months of starting infliximab therapy, “suggesting the possibility of reactivation of latent infection.”
  • M tuberculosis was most common (54/100,000)
  • “In general, anti-TNFα therapy should be discontinued during any severe infection.”

My take: This report offers a lot of information. Its impact on daily practice would be much greater if the authors created a simple one-sheet screening questionnaire form with recommended bloodwork and vaccines.

One Day Polyethylene Glycol 3350 Prep

Posted on by

A recent study (B Sahn et al. JPGN 2016; 63: 19-24) with 155 patients prospectively showed that a 1-day polyethylene glycol (PEG) 3350 prep was safe and fairly effective.

The prep: 4 g/kg PEG in children with weights 10-50 kg and (with 238 gm for those >50 kg along with a single dose of a stimulant: either bisacodyl 5 mg-15 mg orally (10 mg for 21-30 kg) or senna (17.6 mg for 20 kg, 26.4 mg for 21-30 kg, and 52.8 mg for >31 kg).  The PEG was mixed typically with a sports drink to a max of 64 oz.

Key findings:

  • Hypokalemia was noted in 37 (24%) but none lower than 3.3 mmil/L.
  • Hypoglycemia was identified in 5 (3 were younger than 7). The one patient with severe hypoglycemia (31 mg/dL) was a one-year-old with corticosteroid dependency and had missed his morning steroid dose.
  • Colon cleansing was excellent or good in 77%.  The authors note that this suboptimal cleansing is due in part to the difficulty of using split-dosing in pediatrics.
  • 3/4ths of patients found the prep to be easy or average to tolerate.

My take: This study validates the common approach of using 1-day PEG 3350 preps in children.  Due to the low risk of hypoglycemia, particularly in young children, and the frequent mild hypokalemia, some children may benefit from starting intravenous fluids prior to induction of anesthesia.
