Background: Polycystic ovary syndrome (PCOS) and endometriosis are widely recognized as significant risk factors affecting the reproductive health of women. The underlying mechanisms impacting fertility may vary, potentially leading to divergent outcomes. We aimed to examine and contrast the prevalence patterns of diseases coexisting with PCOS and endometriosis, using a large-scale nationwide insurance claims data from Asian women of reproductive age. Methods: We analyzed health insurance and examination data of 157,662 Korean women aged 15–45 years, drawn from the Korea National Health Insurance Service-National Sample Cohort database. International Classification of Disease, Tenth Revision codes were mapped to phenome-wide association study codes (phecodes). Subsequently, multivariate logistic regression was performed to assess the comorbidity patterns among patients diagnosed with PCOS and endometriosis and healthy control groups. Results: Our analysis revealed that PCOS was correlated with a wider range of metabolic disorders and symptoms, such as hyperlipidemia, type 2 diabetes, various gastrointestinal (GI) issues, and an array of pregnancy-related complications. Conversely, endometriosis was more prevalent among benign neoplasms of female reproductive and digestive organs, endometrial hyperplasia, and angina pectoris. Notably, infertility and glaucoma demonstrated significant associations with both conditions. Furthermore, a comparison of symptom-related codes in women with endometriosis revealed a predominance of painrelated symptoms, whereas those with PCOS exhibited a broader spectrum, encompassing pain, pruritus, GI problems, cough, fever, menstrual cycle disorders, edema, and dizziness. Conclusion PCOS and endometriosis, which are prevalent gynecological disorders affecting similar age groups of women, rarely co-occur and exhibit unique comorbidity profiles.Tailored healthcare strategies that take into account these distinct patterns have the potential to enhance long-term healthcare outcomes of affected patients. Further research is required to elucidate the underlying mechanisms and contrasting comorbidity profiles between PCOS and endometriosis.

Ancient bones have undergone natural decomposition and have been exposed to external environment for long period. Ancient DNA from old bone is usually fragmented. In addition, various kinds of inhibitors are co-extracted. All these may inhibit proper sequencing reaction. Cloning is regarded as the standard method when sequencing aDNA. When cloning, each clone from the same sample may not be of same sequence, and to exact consensus sequence may be difficult. Here we present our experience on 1200 year old bone from Russia, Primorsky Kray area. We have tried to sequence for HV I, II region of mtDNA using modified mini-primer set, which consisted of 7 set to cover the HV I, II. We cloned the PCR product and sequenced all the clones. Amplification efficiency and subsequent success rates were different for each mini primer set. Loci of variation that differ from consensus sequences were rather frequent, and the pattern were variable depending on sample. Except major polymorphic sites that are important when haplogroup designation, 16129 was the most frequent site that was discarded when extracting haplogroup designation.

Commercial kits usually recommend certain range of the amount of DNA without PCR inhibitors for optimal results. If proper DNA is not used in STR amplification, undesirable results such as enhanced stutter effects, split peaks, allele dropout and poor peak balance could be shown. This phenomenon would happen more frequently in case of bone typing. Therefore, we checked effect of DNA concentration and PCR inhibitors on conventional STR typing results using QuantifilerTM Human DNA Quantification Kit. The 54 bone samples over a 60-year burial period were used in this study. In all samples, the DNA concentration ranged from 0.8 pg/ul to 748 pg/ul and Ct values of IPC that indicates residue of PCR inhibitors ranged from 26.69 to 35.59. The DNA concentration and the number of amplified loci showed positive correlation. The number of loci amplified using Minifiler kit was much more than using Y filer kit. Samples with high Ct value of IPC were not almost amplified with Y filer kit. These results suggested that QuantifilerTM Kit is useful to obtain information for DNA typing.

STR typing for several loci has been regarded as a standard method for individual identification. The result is rather simple and easy to be interpreted. For each loci one allele for homozygote and two different alleles for heterozygote are expressed as simple peaks. Many peaks more than two suggest unusual situations such as contamination. We experienced two cases of three alleles in two separate samples. Among 15 STR loci typed using AmpFlSTR.. Identifiler.. Kit(Applied Biosystems, Foster City, CA) and Powerplex..16 system (Promega, Madison, WI), three alleles were noted in D8S1179 locus in one sample, in D21S11 locus in another sample. We sequenced all the three amplified alleles through cloning to reveal the structure, and amplified nearby regions to check the extent of three alleles. We present the results here together with review on many alleles in one sample.

OBJECTIVES: The purpose of this study was to develop a systematic and standardized「The Survey on School Foodservice Program」that can identify the current status of school meals on the nationwide level. METHODS: This study was carried out in six steps of the analysis of report/investigation data related to school foodservice in metropolitan and provincial offices of education, analysis of preceding research related to the actual status of school foodservice, field verification of the actual condition of the school foodservice site, development of a draft of「The Survey on School Foodservice Program」, pilot study of a draft of 「The Survey on School Foodservice Program」, and suggestions of a final model of「The Survey on School Foodservice Program」from August to December, 2017. Statistical analysis was performed for frequency analysis and descriptive analysis using the SPSS program ver. 23. RESULTS: A draft of「The Survey on School Foodservice Program」was developed by analyzing the current status of report/research data on school meals in metropolitan and provincial offices of education, analyzing the preceding research on school meals, and identifying the actual conditions at school foodservice sites. To verify the validity of the school foodservice survey questionnaire, 1,031 schools were sampled from a total of 10,251 schools and the pilot test of ‘2017 School Foodservice Survey’ was conducted. The final model of「The Survey on School Foodservice Program」consisted of 12 survey sections, 29 survey categories, and 433 survey items, and the survey cycle was set for one year and three years for each survey item. CONCLUSIONS: Based on the objective statistical data through「The Survey on School Foodservice Program」, it is possible to develop the school foodservice policy, which will help establish the reliability of the school meals.

Peliosis hepatis, an uncommon vascular condition, is characterized by multiple blood-filled cavities distributed throughout the liver. Computed tomography and magnetic resonance imaging findings of peliosis hepatis are nonspecific. A 40-year-old woman presented with multiple hepatic cystic masses. Two years later, the number and sizes of the masses had increased. We suspected metastatic hepatic disease and performed a liver biopsy. Histological examination revealed dilatation of hepatic sinusoids and multiple blood-filled cavities throughout the liver parenchyma. Thus, a diagnosis of peliosis hepatis was confirmed.
