Incontinentia pigmenti (IP) is a rare X-linked skin disease caused by mutations in the IKBKG gene, which is required for activation of the nuclear factor-kappa B signalling pathway. Multiple systems can be affected with highly variable phenotypic expressivity. We aimed to clarify the clinical characteristics observed in molecularly confirmed Korean IP patients. The medical records of 25 females confirmed as IP by molecular genetic analysis were retrospectively reviewed. The phenotypic score of extracutaneous manifestations was calculated to assess the disease severity. The IKBKG gene partial deletion or intragenic mutations were investigated using long-range PCR, multiplex ligation-dependent probe amplification and direct sequencing methods. Among the 25 individuals, 18 (72%) were sporadic cases. All patients showed typical skin manifestations at birth or during the neonatal period. Extracutaneous findings were noted in 17 (68%) patients; ocular manifestations (28%), neurological abnormalities (28%), hair abnormalities (20%), dental anomalies (12%), nail dystrophy (8%). The common exon 4-10 IKBKG deletion was observed in 20 (80%) patients. In addition, five intragenic sequence variants were identified, including three novel variants. The phenotype scores were highly variable, ranging from abnormal skin pigmentation only to one or more extracutaneous features, although no significant difference was observed for each clinical characteristic between the group with sequence variants and that with common large deletion. Our cohort with IP showed heterogeneity of extracutaneous manifestations and high incidence of sporadic cases. Long-term monitoring with multidisciplinary management is essential for evaluating the clinical status, providing adequate genetic counselling and understanding the genotype-phenotype correlation in IP.A high incidence of oral squamous cell carcinoma (OSCC) is observed in South-East Asian countries due to addictions such as chewing tobacco. Local invasion and distant metastases are primary causes of poor prognosis in OSCC. This study aimed to understand the alterations in metastasis biomarkers, such as stromal cell-derived factor-1α (SDF-1 or SDF1α) and its receptor C-X-C chemokine receptor type 4 (CXCR4), in OSCC patient samples that were stratified based on the history of addiction to chewing tobacco. Targeted immunohistochemical staining and Western blotting were performed on primary tumour and metastatic lymph node (LN) tissues in parallel. Overexpression of hepatocyte growth factor (HGF), activated form of its cognate receptor tyrosine kinase, c-Met (p-Met), GRB2-associated-binding protein 1 (Gab1), phospho-protein kinase B (pAkt), nuclear factor kappa B (NF-κB) and cyclooxygenase-2 (COX-2) were observed in primary tumour and metastatic lymph nodes in both chewer and non-chewer cohorts. Variance analysis showed significant positive correlation between them (P less then .0001) indicating upregulation of these biomarkers upon ligand-induced activation of c-Met in both tobacco chewers and non-chewers. Significantly higher expressions of SDF1α and CXCR4 were observed in both primary tumours and metastatic lymph nodes of tobacco chewers (P less then .0001) and coincided with overexpressed HGF. In contrast, no significant correlation was observed between expression of HGF and that of SDF1α and CXCR4 in non-chewers. Together, our findings provide important insights into the association of HGF/c-Met and the SDF1α/CXCR4 axis in lymph node metastasis and to an aetiological link with the habit of chewing tobacco.
To estimate one-year costs of eating disorders in the United States (U.S.) from a societal perspective, including the costs to the U.S. health system, individual and family productivity costs, lost wellbeing, and other societal economic costs, by setting and payer. Findings will inform needed policy action to mitigate the impact of eating disorders in the U.S.

Costs of eating disorders were estimated using a bottom-up cost-of-illness methodology, based on the estimated one-year prevalence of eating disorders. Intangible costs of reduced wellbeing were also estimated using disability-adjusted life years.

Total economic costs associated with eating disorders were estimated to be $64.7 billion (95% CI $63.5-$66.0 billion) in fiscal year 2018-2019, equivalent to $11,808 per affected person (95% CI $11,754-$11,863 per affected person). Otherwise Specified Feeding or Eating Disorder accounted for 35% of total economic costs, followed by Binge Eating Disorder (30%), Bulimia Nervosa (18%) and Anorexia Nervosa (orders in primary care, schools, and workplaces and ensuring access to early evidence-based treatment.
The myeloperoxidase index (MPXI), on ADVIA hematology analyzers, reflects the mean neutrophil myeloperoxidase staining. It is used as a marker of inflammation in animals and people, but assay variability and storage stability are unknown.

We aimed to determine MPXI precision and stability with refrigerated storage of canine and equine EDTA-anticoagulated blood and compared MPXI results between two analyzers.

Inter-assay coefficients of variations (CVs) were determined from three human-based controls assayed before and after a 20- or 21-day calibration. Blood from 14-16 dogs and 26 horses was assayed 4-10 times within 1day for intra-assay CV measurements. Median control and single run results from 18 canine and 35 equine samples were compared between analyzers. Blood from 10-12 dogs and 10-11 horses was analyzed after collection, and 24, 48, and 72hours of refrigerated storage.

Inter-assay CVs of controls were 10.7%-15.9% and 6.4%-9.6% before and 4.3%-7.7% and 2.8%-17.5% after calibration, for ADVIA 1 and 2, respectively. Calibration altered peroxidase gain settings and improved precision. Intra-assay CVs were 0.6%-64% and 3%-350% for canine and equine samples, respectively. Median MPXI results differed significantly between the analyzers, likely from calibration-associated changes in gains. MPXI decreased with storage, and with variable changes between animals and analyzers. Platelet clumps and lipid contributed to the variability in replicate MPXI measurements.

MPXI has a higher variability in equine samples than in canine samples. Equivalent results might not be obtained between analyzers. Results change unpredictably with repeated analyses over 72hours. MPXI measurements might only be useful in controlled research settings.
