OBJECT: Risperidone, unlike other atypical antipsychotics, is thought to elevate prolactin levels. This paper examines the relationship of risperidone-induced hyperprolactinemia and the sexual dysfunctions of the patients in the real clinical practice. METHODS: Forty nine patients (male 22, female 27) with 6 month-over risperidone medication were assigned and serum prolactin was assayed in serum by radioimmunometric assay. In the distinction of sex, six adverse events possibly associated with increased prolactin levels were determined by interviewing the patients (poor erection, ejaculatory dysfunction, galactorrhea, decreased libido, orgasmic dysfunction and obesity in male;amenorrhea, vaginal dryness, galactorrhea, decreased libido, orgasmic dysfunction and obesity in female). RESULTS: In 49 patients, thirty six patients (male 15;56%, female 21;95%) showed hyperprolactinemia and twenty two patients (male 13;48%, female 8;36%) had sexual side-effects. Both risperidone dosage per day and duration were not correlated with prolactin levels and adverse events. There was no significant direct correlation between serum prolactin levels and sexual adverse events. CONCLUSION: The risperidone-associated increase in serum prolactin levels was not significantly directly correlated with the emergence of possible prolactin-related adverse events in the real clinical practice. However, our results suggest that risperidone-induced hyperprolactinemia may play a role in sexual dysfunction of female patients.

PURPOSE: The purpose of this study is to establish the method generating human brain anatomical connectivity from Korean children and evaluating the network topological properties using small-world network analysis. MATERIALS AND METHODS: Using diffusion tensor images (DTI) and parcellation maps of structural MRIs acquired from twelve healthy Korean children, we generated a brain structural connectivity matrix for individual. We applied one sample t-test to the connectivity maps to derive a representative anatomical connectivity for the group. By spatially normalizing the white matter bundles of participants into a template standard space, we obtained the anatomical brain network model. Network properties including clustering coefficient, characteristic path length, and global/local efficiency were also calculated. RESULTS: We found that the structural connectivity of Korean children group preserves the small-world properties. The anatomical connectivity map obtained in this study showed that children group had higher intra-hemispheric connectivity than inter-hemispheric connectivity. We also observed that the neural connectivity of the group is high between brain stem and motorsensory areas. CONCLUSION: We suggested a method to examine the anatomical brain network of Korean children group. The proposed method can be used to evaluate the efficiency of anatomical brain networks in people with disease.

Purpose: Despite research efforts, current fall rates are still higher than expected. To approach this problem, we developed guidelines on preventing falls in hospitals. Methods: Four guidelines were selected by the K-AGREE II process. Recommendations from each guideline were retrieved and evaluated based on the quality of evidence and the strength of the recommendations. Recommendations followed the grading system of the Korean Hospital Nurses Association’s Guideline Adaptation Manual. In the external review, 13 practice nurses from 5 hospitals and 13 panel experts including doctors, nursing managers, and pharmacists participated. Results: The final guideline consisted of 5 sections and 341 recommendations. The first two sections were composed of recommendations for institutional readiness for change process and management, and Section 3 was divided into assessment of risk factors, preventive intervention and post-fall management. The summary of falls risk factors included seven components. Multifaceted interventions were modeled into six strategies. The final sections consisted of recommendations for implementing fall improvement programs and for sustaining effective prevention programs. Conclusion Given that falls result from various combinations of risk factors, the present guideline contains multifaceted assessments and interventions including risk-targeted strategy. This guideline will contribute to decreasing fall rates in hospitals by stimulating compliance with evidence-based practice.

Bone defects are common disease requiring thorough treatments since the bone is a complex vascularized tissue that is composed of multiple cell types embedded within an intricate extracellular matrix (ECM). For past decades, tissue engineering using cells, proteins, and scaffolds has been suggested as one of the promising approaches for effective bone regeneration. Recently, many researchers have been interested in designing effective platform for tissue regeneration by orchestrating factors involved in microenvironment around tissues. Among factors affecting bone formation, vascularization during bone development and after minor insults via endochondral and intramembranous ossification is especially critical for the long-term support for functional bone. In order to create vascularized bone constructs, the interactions between human mesenchymal stem cells (MSCs) and endothelial cells (ECs) have been investigated using both direct and indirect co-culture studies. Recently, various culture methods including micropatterning techniques, three dimensional scaffolds, and microfluidics have been developed to create micro-engineered platforms that mimic the nature of vascularized bone formation, leading to the creation of functional bone structures. This review focuses on MSCs co-cultured with endothelial cells and micro-engineered platforms to determine the underlying interplay between co-cultured MSCs and vascularized bone constructs, which is ultimately necessary for adequate regeneration of bone defects.

Arteriovenous malformation (AVM) of the pancreas is exceedingly rare, although it may be increasingly diagnosed due to the widespread use of cross-sectional imaging of the abdomen; even rarer is its association with pancreatitis. A 45-year-old male was admitted to our hospital with symptom of epigastric pain. Dynamic contrast imaging scans of the abdomen showed a focal acute pancreatitis and pancreatic AVM. The angiography findings were compatible with pancreatic AVM. The cause of abdominal pain was diagnosed by acute pancreatitis caused by pancreatic AVM, and, for definitive treatment of symptomatic pancreatic AVM, distal pancreatectomy with splenectomy was performed. The histological results confirmed the presence of irregular dilated tortuous arteries and veins, and a retention cyst with epithelial cell lining. We experienced a rare case of a 45-year-old-Korean male who had acute pancreatitis associated with pancreatic AVM. Pancreatic AVM is extremely rare; even rarer is its association with pancreatitis.

PURPOSE: The purpose of this study was to examine the relationship between body esteem, stress, and health promoting behaviors among Korean adults in a community and to identify factors that influence health promoting behaviors. METHODS: This study was conducted using a questionnaire which included item for body esteem, stress and health promotion behaviors. Data were collected from 257 adults living in Jeollabuk-do in Korea from November to December, 2015. The collected data were analyzed through descriptive statistics, Pearson's correlation coefficient, and stepwise multiple regression using the SPSS/WIN 21.0 program. RESULTS: The mean score of body esteem was 2.73±0.43, stress was 1.89±0.68, and health promoting behaviors was 2.22±0.45. There was a significant positive correlation between body esteem and health promotion behaviors (r=.47, p<.001), whereas there was a significant negative correlation between stress and health promotion behaviors (r=-.47, p<.001). In stepwise multiple regression analysis, body esteem, religion, education explained approximately 30.1% of health promoting behaviors (F=37.73, p<.001). CONCLUSION: The results in this study indicate that body esteem is the most important factor in health promoting behaviors among Korean adults. Thus, body esteem contents should be included in developing programs for adults to enhance their health promoting behaviors.

Synergistic integration of the Internet of Things (IoT), cloud computing, and big data technologies in healthcare have led to the notion of “smart health.” Smart health is an emerging concept that refers to the provision of healthcare services for prevention, diagnosis, treatment, and follow-up management at any time or any place by connecting information technologies and healthcare. As a significant breakthrough in smart healthcare development, IoT-enabled smart devices allow medical centers to carry out preventive care, diagnosis, and treatment more competently. This review focuses on recently developed patient health monitoring platforms based on IoT-enabled smart devices that can collect real-time patient data and transfer information for assessment by healthcare providers, including doctors, hospitals, and clinics, or for self-management. We aimed to summarize the available information about recently approved devices and state-of-the-art developments through a comprehensive, systematic literature review. In this review, we also discuss possible future directions for the integration of cloud computing and blockchain, which may offer unprecedented breakthroughs in on-demand medical services. The combination of IoT with real-time, remote patient monitoring empowers patients to assert more control over their care, thereby allowing them to actively monitor their particular health conditions.

Various vaccines have been developed to fight severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for the coronavirus disease 2019 pandemic.However, new variants of SARS-CoV-2 undermine the effort to fight SARS-CoV-2. Here, we produced S proteins harboring the receptor-binding domain (RBD) of the Omicron variant in plants. Plant-produced S proteins together with adjuvant CIA09A triggered strong immune responses in mice. Antibodies in serum inhibited interaction of recombinant human angiotensinconverting enzyme 2 with RBD of the Omicron variant, but not RBD of other variants. These results suggest that antibodies induced by RBD of the Omicron variant are highly specific for the Omicron RBD, but not for that of other variants.

BACKGROUND/OBJECTIVES: UV radiation is a major factor contributing to DNA damage in skin cells, including stem cells and mesenchymal stem cells, leading to the depletion of these crucial cells. This study examined whether a mixture of Indian gooseberry and barley sprout (IB) could inhibit UVB irradiation and 3-isobutyl-1-methylxanthine (IBMX)-induced photoaging and oxidative stress in the skin using HaCaT, Hs27, and B16F10 cells.MATERIALS/METHODS: The moisturizing-related factors, the collagen synthesis-related c-Jun N-terminal kinase (JNK)/c-Fos/c-Jun/matrix metalloproteinases (MMPs) pathway, and the melanogenesis-related cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA)/cAMP-responsive binding protein (CREB)/melanocyte inducing transcription factor (MITF)/tyrosinase-related protein (TRP)/tyrosinase activation pathways were analyzed in vitro by an enzyme-linked immunosorbent assay, real-time polymerase chain reaction, and Western blot analysis. RESULTS: The IB complex increased the hyaluronic acid and sphingomyelin levels and the collagenase inhibitory activity, enhanced hydration-related factors, including collagen, hyaluronic acid synthase (HAS), elastin, long chain base subunit 1 (LCB1) (serine palmitoyltransferase; SPT), and delta 4-desaturase sphingolipid 1 (DEGS1), modulated the inflammatory cytokines levels, antioxidant enzyme activities and the NF-κB/MMPs/cyclooxygenase-2 (COX-2) pathway in UVB-irradiated HaCaT cells, and inhibited wrinkle formation by down-regulation of the JNK/c-Fos/c-Jun/MMP pathway and up-regulation of the transforming growth factor-β receptor I (TGFβR1)/small mothers against decapentaplegic homolog (Smad3)/procollagen type I pathway in UVB-irradiated Hs27 cells. Moreover, the IB complex prevented melanin production by down-regulating the PKA/CREB/MITF/TRP-1/TRP-2 pathway in IBMX-induced B16F10 cells. CONCLUSION These findings suggest that the IB complex has the potential to serve as a safeguard, shielding the skin from UVB radiation-induced photo-damage.
