Maspin is a recently described gene with tumor suppressor activity. The gene product is a 42 kD protein with homology to the serpin family of protease inhibitors and may play a role as an inhibitor of tumor cell invasion. The prior observation that invasive breast cancers and their metastases showed decreased maspin protein expression by immunostaining supports this speculation. However, the role of maspin in breast cancer progression has not been studied in detail. We, therefore, studied maspin protein expression in a series of hyperplasia, atypical ductal hyperplasia, intraductal carcinoma and invasive carcinomas. Immunohistochemical staining (IHC) for maspin was performed on paraffin sections of 136 breast specimens using a commercially available monoclonal antibody. Among the 106 cases studied were 36 moderate/florid ductal hyperplasia, 11 atypical ductal hyperplasia (ADH), 29 intraductal carcinoma (IDC) (4 low grade, 13 intermediate grade, 12 high grade) and 30 invasive ductal carcinomas. Thirty cases of normal breast were also studied as control group. IHC stains were scored using a semiquantitative scoring system. The mean IHC scores for maspin for normal, moderate/florid hyperplasia, atypical ductal hyperplasia, intraductal carcinoma, and invasive carcinoma were 5.51 1.30, 7.36 0.72, 3.82 1.60, 4.48 2.69, 3.97 3.30, respectively. These scores for each category were statistically significant (p<0.05), except between ADH and IDC. Maspin protein expression was increased in most cases of moderate/florid hyperplasia, while maspin expression was more heterogeneous in ADH and IDC. In high grade IDC, maspin protein expression was stronger than low and intermediate grade IDC, and this suggests the possibility of a compensatory cellular response against the forces driving further tumor progression. Two thirds of invasive ductal carcinomas expressed maspin protein weakly and focally. All metastatic carcinomas of lymph nodes were negative for maspin. It is possible that high grade IDC with strong maspin expression may represent a subset less likely to progress to invasive cancer. This speculation merits investigation in clinical outcome studies.

Cardiovascular disease (CVD) remains the leading cause of morbidity, mortality, and health care costs in South Korea. The prevalence of preventable and treatable risk factors for CVD such as obesity, hypercholesterolemia, and smoking has continued to increase, despite improvements management of hypertension. Active leadership, participation, and support of professional organizations and medical institutions in national cardiovascular registries and regional treatment network have proven to be effective models to reduce the global burden of CVD in the Europe and North America. Regional treatment network systems for ST-segment elevation myocardial infarction have established to coordinate percutaneous coronary intervention (PCI) treatment centers, non-PCI treatment centers, and emergency centers especially across the Europe. The Act on the Prevention and Management of Cardio-cerebrovascular Disease was enacted in South Korea in 2017 to establish the legal frameworks and a comprehensive plan for the prevention and management CVD and risk factors. To fully achieve the goal of a NationalHealth Plan for Cardiovascular Disease, it is necessary to embark on a nationwide registry project and to promote the regional acute treatment accessibility which can therefore play a key role in achieving the objectives of the 2017 Act. In this regard, the Korean Society of Cardiology advocates a national project for health promotion and cardiovascular prevention to improve cardiovascular outcomes, which includes the expansion and establishment of regional cardiocerebrovascular centers (CCVCs) and new local CCVCs.

Background and Objectives:
The objective of this study was to estimate the supply and demand for cardiologists in Korea and provide evidence for healthcare policy to ensure a stable and adequate workforce for optimal cardiovascular disease management.
Methods:
Past trends of inflow and outflow of cardiologists were used to make crude projections, which were then adjusted based on demands of services to obtain final projections. Inflow of cardiologists was estimated using second-order polynomial regression and demand for cardiology care was estimated using linear regression.
Results:
There were 1,139 active cardiologists who were under the age of 65 in clinical practice in Korea. The estimated number of cardiologists from 2022 to 2040 showed that the number of cardiologists would peak at 1,344 in 2032 and gradually decrease thereafter. We also estimated an increase of 947,811 cases of heart-related procedures annually from 2023 to 2032. The number of heart-related procedures per cardiologist would increase 1.4 times from 12,964 in 2023 to 17,862 in 2032. The estimated number of emergency patients per cardiologist under 50 years old would almost double from 544 in 2022 to 987 in 2032.
Conclusions
We expect significant shortage of cardiologists in Korea within the next 10 years. The number of emergency patients per cardiologist will increase by nearly 50%, leading to high individual workload for cardiologists. To prevent this imbalance between supply and demand, an organized and collective approach by the specialty of cardiology is imperative to produce a balanced workforce.

Vibrio vulnificus is a pathogen causing two types of severe illness, septicemia and wound infections, and is continually detected in marine environments. To investigate the biochemical characteristics and the antimicrobial susceptibility of V. vulnificus isolated from environment of Korea in 2001, the API 20E kit test, PCR, and antibiotic disk diffusion method were performed. A total of 210 V. vulnificus strains was isolated from seawater, shell-fish, sediments, coastal water, aquarium water, sewage, and others. All of the isolates could be divided into 15 groups on the basis of their API 20E profiles, and were positive in Indole test. Only 173 isolates (82.4%) were positive by the PCR amplifying the cytolysinhemolysin gene. Almost all isolates were susceptible to chloramphenicol (99.5%), tetracycline (90.0%), ciprofloxacin (92.4%), trimethoprim/sulfamethoxazole (89.0%), nalidixic acid (87.6%). Some isolates were resistant to cephalothin (57.6%), amikacin (33.3%), cefoxitin (31.9%). One hundred and forty three isolates (68.1%) were resistant to one or more antimicrobial agents. These results show that V. vulnificus environmental isolates possessed various biochemical characteristics, and some isolates were not detected of the cytolysin-hemolysin gene by PCR, and a part of isolates were resistant to multiple antibiotics.

The human cytomegalovirus(HCMV) gene encoding the protein reactive with the sera of HCMV-infected patient was cloned and characterized. A reactive phage clone was screened from a lambda gt11 expression library of cDNA of HCMV AD169 strain using HCMV-infected patient sera. The recombinant protein was expressed as 138 kDa-fusion protein with beta-galactosidase, which was reactive with IgM or IgG HCMV antibody-positive sera, but not with anti-HCMV antibody-negative sera. A homology search of the DNA sequence of the cloned gene with HCMV AD169 sequences revealed that it was composed of 709 base pairs spanning between 0.174 and 0.177 map units of the UL32 region of the HCMV AD169 strain genome. This position corresponded to a part of the gene encoding 150 kDa phosphoprotein-(pp150), a major tegument protein, which was reported as an immunogenic protein which evoked strong and longstanding antibody response and had no sequence homology with the proteins of other herpesviruses. These results suggested that pp150 was an immunogenic protein in natural HCMV infection and therefore this clone was regarded as a useful candidate for developing an antigen for the serodiagnosis of HCMV.

A 64-year-old woman was admitted with vertebral osteomyelitis and polyarthritis (both knees and the right shoulder). She had had no health problems before these conditions developed. Joint culture grew methicillin-resistant Staphylococcus aureus. During hospitalization, hematuria, proteinuria, azotemia, and decreased C3 were reported. The renal biopsy showed mesangial proliferative glomerulonephritis with C3 and IgA co-dominant deposits on immunofluorescence staining. Following incision and drainage of the right shoulder and right knee, and intravenous vancomycin for 15 weeks, the C-reactive protein, proteinuria, hematuria, and C3 level all normalized. Here, we report a case of Staphylococcus-associated glomerulonephritis with a brief review of the literature.
