Nutritional strategies for correcting low glucose values in patients with postbariatric hypoglycaemia: A randomized controlled three-arm crossover trial.
AIM
To evaluate the efficacy of nutritional hypoglycaemia correction strategies in postbariatric hypoglycaemia (PBH) after Roux-en-Y gastric bypass (RYGB).
MATERIALS AND METHODS
In a randomized, controlled, three-arm crossover trial, eight post-RYGB adults (mean [SD] 7.0 [1.4] years since surgery) with PBH ingested a solid mixed meal (584âkcal, 85âg carbohydrates, 21âg fat, 12âg protein) to induce hypoglycaemia on three separate days. Upon reaching plasma glucose of less than 3.0âmmol/L, hypoglycaemia was corrected with 15âg of glucose (G15), 5âg of glucose (G5) or a protein bar (P10, 10âg of protein) in random order. The primary outcome was percentage of time spent in the target plasma glucose range (3.9-5.5âmmol/L) during 40âminutes after correction.
RESULTS
Postcorrection time spent in the target glucose range did not differ significantly between the interventions (Pâ=â.161). However, postcorrection time with glucose less than 3.9âmmol/L was lower after G15 than P10 (Pâ=â.007), whereas time spent with glucose more than 5.5âmmol/L, peak glucose and insulin 15âminutes postcorrection were higher after G15 than G5 and P10 (Pâ<â.001). Glucagon 15âminutes postcorrection was higher after P10 than after G15 and G5 (Pâ=â.002 and Pâ=â.003, respectively). G15 resulted in rebound hypoglycaemia (<â3.0âmmol/L) in three of eight cases (38%), while no rebound hypoglycaemia occurred with G5 and P10.
CONCLUSIONS
Correcting hypoglycaemia with 15âg of glucose should be reconsidered in post-RYGB PBH. A lower dose appears to sufficiently increase glucose levels outside the critical range in most cases, and complementary nutrients (e.g. proteins) may provide glycaemia-stabilizing benefits.

Clinical and genetic characteristics of late-onset Huntington's disease
Background: The frequency of late-onset Huntington's disease (>59 years) is assumed to be low and the clinical course milder. However, previous literature on late-onset disease is scarce and inconclusive. Objective: Our aim is to study clinical characteristics of late-onset compared to common-onset HD patients in a large cohort of HD patients from the Registry database. Methods: Participants with late- and common-onset (30â50 years)were compared for first clinical symptoms, disease progression, CAG repeat size and family history. Participants with a missing CAG repeat size, a repeat size of â€35 or a UHDRS motor score of â€5 were excluded. Results: Of 6007 eligible participants, 687 had late-onset (11.4%) and 3216 (53.5%) common-onset HD. Late-onset (n = 577) had significantly more gait and balance problems as first symptom compared to common-onset (n = 2408) (P <.001). Overall motor and cognitive performance (P <.001) were worse, however only disease motor progression was slower (coefficient, â0.58; SE 0.16; P <.001) compared to the common-onset group. Repeat size was significantly lower in the late-onset (n = 40.8; SD 1.6) compared to common-onset (n = 44.4; SD 2.8) (P <.001). Fewer late-onset patients (n = 451) had a positive family history compared to common-onset (n = 2940) (P <.001). Conclusions: Late-onset patients present more frequently with gait and balance problems as first symptom, and disease progression is not milder compared to common-onset HD patients apart from motor progression. The family history is likely to be negative, which might make diagnosing HD more difficult in this population. However, the balance and gait problems might be helpful in diagnosing HD in elderly patients
