Several guidelines are available for identification and management of patients with Gaucher disease, but the most recent guideline was published in 2013. Since then, there have been significant advances in newborn screening, phenotypic characterization, identification of biomarkers and their integration into clinical practice, and the development and approval of new treatment options. Accordingly, the goal of this Delphi consensus exercise was to extend prior initiatives of this type by addressing issues related to newborn screening, diagnostic evaluations, and treatment (both disease directed and adjunctive). The iterative Delphi process involved creation of an initial slate of statements, review by a steering committee, and three rounds of consensus development by an independent panel. A preliminary set of statements was developed by the supporting agency based on literature searches covering the period from 1965 to 2020. The Delphi process reduced an initial set of 185 statements to 65 for which there was unanimous support from the panel. The statements supported may ultimately provide a framework for more detailed treatment guidelines. In addition, the statements for which unanimous support could not be achieved help to identify evidence gaps that are targets for future research.Creatine deficiency syndromes (CDS) are inherited metabolic disorders caused by mutations in GATM, GAMT and SLC6A8 and mainly affect central nervous system (CNS). AGAT- and GAMT-deficient patients lack the functional brain endogenous creatine (Cr) synthesis pathway but express the Cr transporter SLC6A8 at blood-brain barrier (BBB), and can thus be treated by oral supplementation of high doses of Cr. For Cr transporter deficiency (SLC6A8 deficiency or CTD), current treatment strategies benefit one-third of patients. However, as their phenotype is not completely reversed, and for the other two-thirds of CTD patients, the development of novel more effective therapies is needed. This article aims to review the current knowledge on Cr metabolism and CDS clinical aspects, highlighting their current treatment possibilities and the most recent research perspectives on CDS potential therapeutics designed, in particular, to bring new options for the treatment of CTD.Zoonotic cryptosporidiosis is a major public health problem in industrialized nations; in those countries it is caused mainly by Cryptosporidium parvum IIa subtypes that are prevalent in dairy calves. Because of the short history of intensive animal farming in China, strains of C. parvum are found only on some dairy farms in this country and are the IId subtypes. However, the prevalence of C. parvum is increasing rapidly, with IIa subtypes recently detected in a few grazing animals, and both IIa and IId subtypes are emerging in humans. As animal farming intensifies, China may follow in the footsteps of industrialized nations where zoonotic cryptosporidiosis is rampant. One Health and biosecurity measures are urgently needed to slow down the dispersal of autochthonous IId subtypes and imported IIa subtypes.

Nonsyndromic congenital mitten hand with thumb and index finger syndactyly is rare. Gamcemetinib Reconstruction of this condition is challenging, requiring repositioning of the thumb and creation of a wide and deep first webspace. The aim of this paper is to describe the characteristics of patients with this condition and also to describe our surgical technique.

We describe our technique in 16 consecutive children utilizing complete mobilization of the first metacarpal and thumb as an island flap on the neurovascular bundle, with a rotational osteotomy to reposition the thumb in pronation. In addition, a dorsal M flap was used to reconstruct the first webspace. Patients in this series also had varying degrees of symbrachydactyly with hypoplastic or aplastic phalanges of the central digits.

There were 9 male and 7 female patients, with a mean age of 24.4±22.4 months at the time of surgery. Mean follow-up was 19.1±18.3 months. link2 All reconstructions healed well. The mean thumb web distance in the affected hands was 4.2cm (range 3.5 to 5). All reconstructed thumbs had a good opposition. Two children initially had mild hypertrophic scarring, which resolved with pressure gloves. No other complications were observed.

One-stage reconstruction of the thumb and first webspace can be effectively achieved with our technique of complete mobilization of the thumb unit, rotational osteotomy, and a dorsal interdigitating M flap.

Lymphatic ultrasound is a newly developed method to observe the lymphatic vessels. In this study, we compared the diameter of lymphatic vessels observed on preoperative ultrasound with the actual lymphatic diameter (LD) of lymphatic vessels observed intraoperatively.

The study included 32 lower limbs in 17 patients with lower limb lymphedema. Lymphatic ultrasound was performed using a commonly used ultrasound device, Noblus ultrasound system, with an 18MHz linear probe on preoperative day 1. We tracked the lymphatic vessels along the great saphenous vein, at the lateral calf, and at the lateral thigh, based on the lymphosome principle. We measured the cross-sectional height (CSH) and the cross-sectional width (CSW) of lymphatic vessels using ultrasound at the incision sites. Intraoperatively, we measured the diameter of the lymphatic vessel. Based on lymphatic degeneration, lymphatic vessels were categorized into four types using the normal-, ectasis-, contraction-, and sclerosis-type (NECST) classification.

We evaluated 68 lymphatic vessels. The mean CSH, CSW, and LD were 0.65±0.35mm, 1.3±0.41mm, and 0.79±0.35mm, respectively. The correlation coefficient between the CSH and the LD was 0.36 and that between the CSW and LD was 0.24. A significant difference was observed in CSH between the ectasis and contraction types (p=0.0025).

We can somehow predict the size of the lymphatic vessels with CSH in the lymphatic ultrasound, whereas CSW is not reliable.

There is a strong association between nutrition and long-term FEV1 in cystic fibrosis (CF), but studies have been driven by data from subjects with pancreatic insufficiency (PI-CF). We thus evaluated the association between body mass index (BMI) and FEV1 percent-predicted (FEV1pp) in children with pancreatic sufficiency (PS-CF) and contrasted it with the association in PI-CF.

We utilized data from the CF Foundation Patient Registry. The cohort included children born 1995-2010, diagnosed <2 years of age, and who had annualized data on BMI percentile and FEV1pp at ages 6-16 years. Pancreatic status was defined based on pancreatic enzyme replacement therapy. The association between BMI and FEV1 was evaluated using linear and mixed-effects longitudinal regression.

There were 424 children with PS-CF and 7,849 with PI-CF. The association between BMI and FEV1 differed significantly by pancreatic status each 10-pct higher BMI was associated with 2% [95%CI=1.9-2.1] higher FEV1pp in PI-CF, compared to just 0.9% [0.5-1.3] in PS-CF (P

<0.001). Within the at-risk nutritional category (BMI <25pct), each 10-pct higher BMI was associated with 5% higher FEV1pp in PI-CF, but no significant increase in PS-CF. Moreover, in PS-CF, overweight/obesity (BMI ≥85pct) was associated with decreasing FEV1pp. In addition, FEV1pp decline through age 20 years in youth with PS-CF was modest (-0.6% per year) and independent of BMI (BMI*age P

=0.37).

In children with PS-CF, BMI remains an important determinant of lung function. However, it may be less critical to attain a BMI >50

percentile; and BMI ≥85

percentile may be detrimental.

50th percentile; and BMI ≥85th percentile may be detrimental.

Antisense oligonucleotide- based drugs for splicing modulation were recently approved for various genetic diseases with unmet need. Here we aimed to generate skipping over exon 23 of the CFTR transcript, to eliminate the W1282X nonsense mutation and avoid RNA degradation induced by the nonsense mediated mRNA decay mechanism, allowing production of partially active CFTR proteins lacking exon 23.

∼80 ASOs were screened in 16HBEge W1282X cells. ASO candidates showing significant exon skipping were assessed for their W1282X allele selectivity and the increase of CFTR protein maturation and function. The effect of a highly potent ASO candidates was further analyzed in well differentiated primary human nasal epithelial cells, derived from a W1282X homozygous patient.

ASO screening led to identification of several ASOs that significantly decrease the level of CFTR transcripts including exon 23. These ASOs resulted in significant levels of mature CFTR protein and together with modulators restore the channel function following free uptake into these cells. Importantly, a highly potent lead ASOs, efficiently delivered by free uptake, was able to increase the level of transcripts lacking exon 23 and restore the CFTR function in cells from a W1282X homozygote patient.

The highly efficient exon 23 skipping induced by free uptake of the lead ASO and the resulting levels of mature CFTR protein exhibiting channel function in the presence of modulators, demonstrate the ASO therapeutic potential benefit for CF patients carrying the W1282X mutation with the objective to advance the lead candidate SPL23-2 to proof-of-concept clinical study.

In data assimilation, these models are tested against time-ordered data. Recent progress on Bayesian data assimilation demonstrates that this approach combines the strengths of statistical modeling of individual differences with the those of dynamical cognitive models.

The term bilateral vestibulopathy (BV) was recently defined by the Bárány Society. Loss of otolith function was not included in their criteria. link3 Although spontaneous progression to complete bilateral impairment of vestibular function is expected, it is unlikely that patients with advanced BV will continue to present episodes of intense vertigo. Here, following CARE case report guidelines, we report the case of patients meeting the criteria for BV and still disabled by vertigo.

Three patients evaluated in our department meeting the Bárány criteria for definite BV but still complaining of disabling rotatory vertigo were included. All underwent clinical and instrumental vestibular examination. The observations are reported.

In case of BV, the conservation of a stable otolithic reference frame could allow patients to optimize postural strategy. It would be useful to revisit a classification of BV by stages, by introducing an evaluation of otolithic function and postural control for possible subsequent vestibular implantation.
