The purposes of this study were to investigate the perception and needs of community nutrition programs for 379 community residents of 23 health centers where the pilot community nutrition programs are intervening. The awareness rate of the nutrition programs was 54.3% and the reason of the awareness was mainly happened to know when visiting health centers'. More than 90% of the respondents responded that public health nutrition services are necessary. But the residents who experienced the nutrition services showed higher needs of the programs(97.3%) and improved the impression about the roles of health centers(93.6%). They also showed a higher rate of balanced dieting, stronger intentions to change their inappropriate eating style and a higher practicing rate. The more they believed in the provided nutrition information, the more they showed concerns about their diet and practicing rate of the advices from nutritionists. These results show the positive and successful impact of the pilot nutrition programs on the community residents. We need strategies for a more active improvement of the programs and to maintain more qualified public health nutritionists to carry out targeted community nutrition programs.

Purpose:
This study compared clinical and radiologic differences between cystic biliary atresia (cBA) and choledochal cyst (CC) type Ia/b.
Methods:
Infants (≤12 months old) who were diagnosed with cBA or CC type Ia/b from 2005 to 2019 were retrospectively reviewed. Imaging features on preoperative ultrasonography (US) and magnetic resonance imaging (MRI) were compared between the cBA and CC groups. Logistic regression and area under the receiver operating characteristic curve (AUC) analyses were performed for the diagnosis of cBA. Changes in cyst size were also evaluated when prenatal US exams were available.
Results:
Ten patients (5.5% of biliary atresia cases) with cBA (median age, 48 days) and 11 infants with CC type Ia/b (Ia:Ib=10:1; median age, 20 days) were included. Triangular cord thickness on US (cutoff, 4 mm) showed 100% sensitivity and 90.9% specificity (AUC, 0.964; 95% confidence interval [CI], 0.779 to 1.000) and cyst size on MRI (cutoff, 2.2 cm) had 70% sensitivity and 100% specificity (AUC, 0.900; 95% CI, 0.690 to 0.987) for diagnosing cBA. Gallbladder mucosal irregularity on US and an invisible distal common bile duct on MRI were only seen in the cBA group (10 of 10). Only the CC group showed prenatal cysts exceeding 1 cm with postnatal enlargement.
Conclusion
Small cyst size (<1 cm) on prenatal US, triangular cord thickening (≥4 mm) and gallbladder mucosal irregularity on postnatal US, and small cyst size (≤2.2 cm) and an invisible distal common bile duct on MRI can discriminate cBA from CC type Ia/b in infancy.

Neurodevelopmental disorders are complex conditions that pose difficulty in the modulation of proper motor, sensory and cognitive function due to dysregulated neuronal development. Previous studies have reported that an imbalance in the excitation/ inhibition (E/I) in the brain regulated by glutamatergic and/or GABAergic neurotransmission can cause neurodevelopmental and neuropsychiatric behavioral deficits such as autism spectrum disorder (ASD). NMDA acts as an agonist at the NMDA receptor and imitates the action of the glutamate on that receptor. NMDA however, unlike glutamate, only binds to and regulates the NMDA receptor subtypes and not the other glutamate receptors. This study seeks to determine whether NMDA administration in mice i.e., over-activation of the NMDA system would result in long-lasting behavioral deficits in the adolescent mice. Both gender mice were treated with NMDA or saline at early postnatal developmental period with significant synaptogenesis and synaptic maturation. On postnatal day 28, various behavioral experiments were conducted to assess and identify behavioral characteristics. NMDAtreated mice show social deficits, and repetitive behavior in both gender mice at adolescent periods. However, only the male mice but not female mice showed increased locomotor activity. This study implies that neonatal exposure to NMDA may illicit behavioral features similar to ASD. This study also confirms the validity of the E/I imbalance theory of ASD and that NMDA injection can be used as a pharmacologic model for ASD. Future studies may explore the mechanism behind the gender difference in locomotor activity as well as the human relevance and therapeutic significance of the present findings.

PURPOSE: Transforming Growth Factor-beta1(TGF-beta1) is the most potent inhibitor of the progression of normal mammary epithelial cells through the cell cycle. However, advanced breast cancers are mostly refractory to TGF-beta mediated growth inhibition and produce large amounts of TGF-beta, which may enhance tumor cell invasion and metastasis by its effects on extracellular matrix. Yet, little is known about the association of TGF-beta1 with progression of malignant disease in vivo. In this study, we evaluated the preoperative and postoperative plama level of TGF- in breast cancer and analyzed the utility of plasma TGF-beta1 as possible tumor marker. MATERIALS AND METHODS: ELISA(enzyme-linked immunosorbent assay) was used to measure plasma TGF-beta1 level in 45 newly diagnosed breast cancer patients and in 15 normal healthy people, and the results were compared with clinicopathologic characteristics. RESULTS: The mean plasma TGF-beta1 levels were 1.73+/-0.47 ng/ml in normal people and 5.05+/-1.41 ng/ml in breast cancer patiens. In 37 operated patients, the preoperative plasma TGF-beta1 level was 6.34+/-1.34 ng/ml and decreased to 4.48+/-1.07 ng/ml in patients with follow-up after surgery and 4.74+/-0.79 ng/ml in patients with chemotherapy. However, there was no significant correlation between plasma TGF-beta1 level and known prognostic factors including tumor size, LN involvement, tumor grade, hormone receptor status, and pathology. CONCLUSION: These findings suggest that the plasma TGF-g level can be a tumor marker in breast cancer patients and the association with progression of breast cancer will be explored in future studies.

PURPOSE: While there is an urgent need for diagnosis and therapeutic intervention in patients with primary immunodeficiency diseases (PIDs), current genetic tests have drawbacks. We retrospectively reviewed the usefulness of flow cytometry (FCM) as a quick tool for immunophenotyping and functional assays in patients suspected to have PIDs at a single tertiary care institute.METHODS: Between January 2001 and June 2018, patients suspected of having PIDs were subjected to FCM tests, including lymphocyte subset analysis, detection of surface- or intracellular-target proteins, and functional analysis of immune cells, at Samsung Medical Center, Seoul, Korea. The genetic diagnosis was performed using Sanger or diagnostic exome sequencing.RESULTS: Of 60 patients diagnosed with definite or probable PID according to the European Society of Immune Deficiencies criteria, 24 patients were provided with useful information about immunological dysfunction after initial FCM testing. In 10 patients, the PID diagnosis was based on abnormal findings in FCM testing without genetic tests. The FCM findings provided strong evidence for the diagnosis of severe combined immunodeficiency (n = 6), X-linked chronic granulomatous diseases (CGD) (n = 6), leukocyte adhesion deficiency type 1 (n = 3), X-linked agammaglobulinemia (n = 11), autoimmune lymphoproliferative syndrome-FASLG (n = 1), and familial hemophagocytic lymphohistiocytosis type 2 (n = 1), and probable evidence for autosomal recessive-CGD (n = 2), autosomal dominant-hyper-immunoglobulin E (IgE)-syndrome (n = 1), and STAT1 gain-of-function mutation (n = 1). In PIDs derived from PIK3CD (n = 2), LRBA (n = 2), and CTLA4 mutations (n = 3), the FCM test provided useful evidence of immune abnormalities and a tool for treatment monitoring.CONCLUSIONS: The initial application of FCM, particularly with known protein targets on immune cells, would facilitate the timely diagnosis of PIDs and thus would support clinical decisions and improve the clinical outcome.

BACKGROUND: Characterization of clinical features of bacteremic severe sepsis acquired from the community has been inadequate; therefore, our goal in this study was to identify prognostic factors associated with outcome in patients with community-acquired bacteremic severe sepsis. MATERIALS AND METHODS: Adult patients (> or =18 years) with community-acquired severe sepsis in whom pathogens were identified from blood cultures were included in the study. Data were collected prospectively from 12 teaching hospitals between May, 2005, and February, 2009. Data included demographic characteristics, co-morbid medical conditions, primary infection sites, sepsis severity, mortality, causative microorganisms, and the appropriateness of initial empirical antibiotic therapy. RESULTS: During the study period, 1,152 patients were diagnosed with community-acquired severe sepsis and 422 patients were found to harbor pathogens in their blood. Among the 422 patients analyzed, 253 (60.0%) patients went into shock and 121 patients (28.7%) died during hospitalization. Risk factors, including respiratory tract infection (odds ratio [OR], 2.60; 95% confidence interval [CI], 1.11-6.09), number of organ dysfunctions (OR, 1.39; 95% CI, 1.13-1.71), and higher APACHE II scores (OR, 1.08; 95% CI, 1.03-1.13) showed an association with poor survival, whereas Escherichia coli as a pathogen (OR, 0.31; 95% CI, 0.16-0.64) showed an association with lower mortality. CONCLUSIONS: In addition to severity of illness, the primary site of infection and causative microorganisms were also identified as important prognostic factors in patients with community-acquired bacteremic severe sepsis.
