Background:
New alternative types of pet foods such as raw and cooked homemadestyle diets containing human food ingredients have been introduced due to a trend of pet humanization and diversification of consumer needs.
Objectives:
To evaluate nutritional adequacy of new alternative types of dog foods containing human food ingredients as maintenance diets for dogs.
Methods:
Eleven homemade-style foods for adult dogs were purchased from online channel in Korea and analyzed to evaluate nutritional adequacy for adult dogs. Nutrients analyzed included crude protein, amino acids, crude fat, fatty acids, and minerals.
Results:
Crude protein and amino acids in all products satisfied Association of American Feed Control Officials (AAFCO) requirements. Crude fat in one of 11 products did not meet AAFCO requirements. The most deficient minerals were selenium (10 of 11, 90.9%), copper (five of 11, 45.5%), zinc (five of 11, 45.5%), potassium (three of 11, 27.3%), calcium (three of 11, 27.3%), iron (two of 11, 18.2%), and magnesium (one of 11, 9.1%). Six products were not in the range of the recommended Ca:P ratio in AAFCO dog food maintenance nutrient profiles.
Conclusions
This study performed nutritional evaluation of raw and cooked homemadestyle foods as maintenance diets for adult dogs. Some nutritional inadequacies were observed including some minerals, Ca:P ratio, and omega-6:omega-3 fatty acid ratio, although three products (26.2%) satisfied the AAFCO standard except selenium. Overall, the data suggest a need for accurate nutritional adequacy statement for consumers based on proper methods to validate the formula.

Background:
Following success of the phase III PROfound trial, the poly (ADP-ribose) polymerase (PARP) inhibitor olaparib was approved by the US Food and Drug Administration in May 2020 for adult patients with deleterious homologous recombination repair (HRR) gene-mutated metastatic castration-resistant prostate cancer (mCRPC). As locally adopted multigene panel next-generation sequencing (NGS) assays for selecting PARP inhibitor candidates have not been thoroughly evaluated, we compared the analytical performance of the FoundationOne CDx (Foundation Medicine, Inc., Cambridge, MA, USA) (central laboratory) and other NGS assays (local laboratory) with samples from the PROfound trial in Korea.
Methods:
One hundred PROfound samples (60 HRR mutation [HRRm] cases and 40 non-HRRm cases) were analyzed. The results of HRR gene mutation analysis were compared between the FoundationOne CDx and two other NGS assays [SureSelect Custom Design assay (Agilent Technologies, Inc., Santa Clara, CA, USA) and Oncomine Comprehensive assay (Thermo Fisher Scientific, Inc., Waltham, MA, USA)].
Results:
The positive percent agreement for single nucleotide variants (SNVs) and insertion/deletions (indels) between the central laboratory and local laboratory was 98.7%–100.0%. The negative percent agreement and overall percent agreement (OPA) for SNVs and indels between central and local laboratories were both 100%. Compared with that of the FoundationOne CDx assay, the OPA for copy number variations of the Oncomine Comprehensive and SureSelect Custom assays reached 99.8%–100%. Most mCRPC patients harboring a deleterious genetic variant were successfully identified with both local laboratory assays.
Conclusions
The NGS approach at a local laboratory showed comparable analytical performance for identifying HRRm status to the FoundationOne CDx assay used at the central laboratory.
4.A Web-Based Pulse Wave Information Management System.
Journal of Korean Society of Medical Informatics 2002;8(3):47-53
This paper describes a web-based pulse wave information management system that applies the web solution to the pulse wave extraction and management of the patient's bio-signals. In the oriental medicine, the abnormal arterial pulse wave signals generated from the specific point of body are thought to be related to certain disease conditions of specific internal organs. Therefore, evaluating the pulse wave signals has long been used a major diagnostic means. Numerous studies have been carried out on the development of the pulse wave measuring instruments that c an simply check the one's pulse waves on the radial artery, however, fewer researches have been performed to analyze pulse waves and manage the information in association with the oriental medical information system. Recently, as the usage of instrumental pulse wave analysis is increasing in the practice of the oriental medicine, needs of the pulse wave information management system that can be interfaced with the oriental medical information system are also inc reasing. The web-based pulse wave information management system provides ea sy acc ess, analysis and management of the pulse waves at anywhere one just connects the pulse wave analyser and web browser with the server system and it can also provide the high availability of the pulse wave data. All pulse wave data were easily managed with XML based communication for interchange of the pulse wave data among the existing oriental medicine information systems.
