Survival of very-low-birth-weight infants (VLBWI) depends on professional perinatal management that begins at delivery. Korean Neonatal Network data on neonatal resuscitation management and initial care of VLBWI of less than 33 weeks gestation born from January 2013 to June 2014 were reviewed to investigate the current practice of neonatal resuscitation in Korea. Antenatal data, perinatal data, and short-term morbidities were analyzed. Out of 2,132 neonates, 91.7% needed resuscitation at birth, chest compression was performed on only 104 infants (5.4%) and epinephrine was administered to 80 infants (4.1%). Infants who received cardiac compression and/or epinephrine administration at birth (DR-CPR) were significantly more acidotic (P < 0.001) and hypothermic (P < 0.001) than those who only needed positive pressure ventilation (PPV). On logistic regression, DR-CPR resulted in greater early mortality of less than 7 days (OR, 5.64; 95% CI 3.25-9.77) increased intraventricular hemorrhage > or = grade 3 (OR, 2.71; 95% CI 1.57-4.68), periventricular leukomalacia (OR, 2.94; 95% CI 1.72-5.01), and necrotizing enterocolitis (OR, 2.12; 95% CI 1.15-3.91) compared with those infants who needed only PPV. Meticulous and aggressive management of infants who needed DR-CPR at birth and quality improvement of the delivery room management will result in reduced morbidities and early death for the vulnerable VLBWI.

Purpose: The purpose of this study is to examine the effects of the rural elderly suicide literacy level upon suicide stigma and coping advice with suicidal crises (recommending professional help for a suicidal person). In particular, this study investigates the role of cultural norms (perceived social expectations for the experience of negative emotions) on suicide stigma and coping ability. Methods: A survey was conducted addressing elderly people (N=119) living in rural areas. Regression analysis using SPSS PROCESS macro was used to examine the relationships among the key variables. Results: Participants with higher suicide literacy showed lower suicide stigma, and this perception had a significant effect on enhancing their coping advice with suicidal crises. Also, perceived social expectations significantly influenced the relationship between suicide stigma and coping advice. With lower levels of social expectations, the mediating effect of suicide stigma on the relationship between suicide literacy and recommending professional help did not exist whereas the indirect effect was significant when it pertained to high levels of social expectations. Conclusion This result signifies that suicide stigma serves as a barrier deterring Koreans from reaching out for professional help regarding their mental health. Moreover, these findings underscore the importance of cultural psychological factors such as perceived social expectations in terms of developing suicide prevention strategies.

Palpable axilla mass in woman is relatively rare. Almost all palpable lumps in axilla are axillarys accessory breasts without mass lesion. All diseases develop in breast can also develop in axillarys accessory breasts and other soft tissue mass can occur in axilla. Malignant fibrous histiocytoma (MFH) is the most common malignant soft tissue tumor, but axillarys MFH is extremely rare. We report our experience with a 75-year-old woman with MFH in axilla, treated with wide excision.

A series of five endodermal sinus tumors was studied for their cytoskeletal and other phenotypic markers. They included 2 ovarian, 2 testicular, and 1 inguinal tumors. The cytoskeletal expression was also studied by gel electrophoresis and immunoblotting. Every tumor was diffusely and strongly immunostained for cytokeratin. By SDS-PAGE and immunoblotting, cytokeratins 8 & 18 were detected. Vimentin was focally coexpressed in 4 cases. The stroma was diffusely immunostained for vimentin. None of them expressed desmin, neurofilament, or glial filament protein. Desmoplakin was expressed only in one ovarian tumor. Alpha-fetoprotein and S-100 protein were also diffusely positive among the neoplastic cells; intracytoplasmic globules were especially strongly immunostained. These findings suggest that endodermal sinus tumors represent a group of pure malignant epithelial neoplasms, and may be regarded as primitive carcinomas.

Extrafollicular reticulum cells in lymph nodes are heterogeneous. They express cytokeratins, desmin, and/or vimentin as their intermediate filament profile. Using those markers, we undertook an immunohistochemical study of human lymph nodes under various pathologic conditions. Samples included 15 simple reactive lymph nodes, 7 follicular hyperplasia, 1 necrotizing lymphadenitis, 4 tuberculous lymphadenitis, 13 malignant lymphoma (9 non-Hodgkin's and 4 Hodgkin's lymphomas), and 11 metastatic adenocarcinoma. In lymph nodes with follicular hyperplasia, cytokeratin and/or desmin expressing reticulum cells displayed a characteristic dendritic meshwork in the subcapsular, perisinusoidal, and paracortical regions. In other forms reactive lymph nodes, they were similarly distributed but were less prominent. By SDS-PAGE and immunoblotting, cytokeratin polypeptides were identified. In necrotizing lymphadenitis, they were increased and the pattern of distribution was disturbed. In tuberculous lymphadenitis, they were also increased and located at nongranulomatous as well as in perigranulomatous areas. In lymphomas the reticular meshwork was entirely obliterated. Cytokeratin or desmin expressing reticulum cells were rarely seen within tumors. The reticular meshwork was also obliterated in metastatic carcinoma. However, the meshwork was maintained in uninvolved areas. In conclusion, extrafollicular reticulum cells displayed characteristic patterns of distribution under various pathologic conditions, and may be implicated in the pathogenesis of those pathologic conditions in human lymph nodes.

BACKGROUND: This study evaluated echocardiographic changes in full-term healthy neonates during early transitional period from postnatal 0–72 hours at 12-hour intervals by echocardiography. METHODS: This was a prospective, observational, and longitudinal single-center cohort study. Morphometric, functional, systolic, diastolic, and tissue Doppler imaging (TDI) parameters (patent ductus arteriosus [PDA], aorta, superior vena cava [SVC], stroke volume [SV], cardiac output [CO], cardiac index [CI], early diastolic flow velocity [E], late diastolic flow velocity [A], early filling in TDI [E′], peak systolic annular velocity in TDI [S′], late velocity peak in TDI [A′], and myocardial performance index [MPI]) were evaluated in left ventricle (LV) and right ventricle (RV) with 56 newborns. RESULTS: Sizes and peak velocities of PDA before postnatal 24 hours were significantly changed than those after postnatal 24 hours. Aortic velocity time integral (VTI), systolic blood pressure (BP), LV SV/kg, LV CO/kg, LV CI, and SVC flow/LV CO before 24 hours showed significantly changes than those after 24 hours. Also, LV and RV MPI before 24 hours were significantly higher than those after 24 hours. LV E/E′ was significantly higher than RV E/E′. CONCLUSION: Postnatal 24 hours is critical time for hemodynamic closure of PDA because aortic VTI, systolic BP, LV SV, LV CO, LV CI, and SVC flow/LV CO showed simultaneously significant changes after 24 hours at the same time as 24 hours of physiological closure of PDA. Chronological and dramatic changes of systolic, diastolic, and TDI parameters during early postnatal period can be used to compile normal baseline data of healthy full-term neonates.

Background: To investigate the real-world safety and effectiveness of dulaglutide in Korean adults with type 2 diabetes mellitus (T2DM). Methods: This was a real-world, prospective, non-interventional post-marketing safety study conducted from May 26, 2015 to May 25, 2021 at 85 Korean healthcare centers using electronic case data. Data on patients using dulaglutide 0.75 mg/0.5 mL or the dulaglutide 1.5 mg/0.5 mL single-use pens were collected and pooled. The primary objective was to report the frequency and proportion of adverse and serious adverse events that occurred. The secondary objective was to monitor the effectiveness of dulaglutide at 12 and 24 weeks by evaluating changes in glycosylated hemoglobin (HbA1c ), fasting plasma glucose, and body weight. Results: Data were collected from 3,067 subjects, and 3,022 subjects who received ≥1 dose (of any strength) of dulaglutide were included in the safety analysis set (53% female, mean age 56 years; diabetes duration 11.2 years, mean HbA1c 8.8%). The number of adverse events reported was 819; of these, 68 (8.3%) were serious adverse events. One death was reported. Adverse events were mostly mild in severity; 60.81% of adverse events were considered related to dulaglutide. This study was completed by 72.73% (2,198/3,022) of subjects. At 12/24 weeks there were significant (P<0.0001) reductions from baseline in least-squares mean HbA1c (0.96%/0.95%), fasting blood glucose (26.24/24.43 mg/dL), and body weight (0.75/1.21 kg). Conclusion Dulaglutide was generally well tolerated and effective in real-world Korean individuals with T2DM. The results from this study contribute to the body of evidence for dulaglutide use in this population.

Background: This retrospective study aimed to determine the treatment patterns and the surgical and oncologic outcomes after completion lobectomy (CL) in patients with locoregionally recurrent stage I non-small cell lung cancer (NSCLC) who previously underwent sublobar resection. Methods: Data from 36 patients who initially underwent sublobar resection for clinical, pathological stage IA NSCLC and experienced locoregional recurrence between 2008 and 2016 were analyzed. Results: Thirty-six (3.6%) of 1,003 patients who underwent sublobar resection for NSCLC experienced locoregional recurrence. The patients’ median age was 66.5 (range, 44–77) years at the initial operation, and 28 (77.8%) patients were men. Six (16.7%) patients underwent segmentectomy and 30 (83.3%) underwent wedge resection as the initial operation.The median follow-up from the initial operation was 56 (range, 9–150) months. Ten (27.8%) patients underwent CL, 22 (61.1%) underwent non-surgical treatments (chemotherapy, radiation, concurrent chemoradiation therapy), and 4 (11.1%) did not receive treatment or were lost to follow-up after recurrence. Patients who underwent CL experienced no significant complications or deaths. The median follow-up time after CL was 64.5 (range, 19–93) months. The 5-year overall survival (OS) and post-recurrence survival (PRS) were higher in the surgical group than in the non-surgical (p<0.001) and no-treatment groups (p<0.001). Conclusion CL is a technically demanding but safe procedure for locoregionally recurrent stage I NSCLC after sublobar resection. Patients who underwent CL had better OS and PRS than patients who underwent non-surgical treatments or no treatments; however, a larger cohort study and long-term surveillance are necessary.
