RESUMO
BACKGROUND: The pathogens involved in central nervous system (CNS) infections are various, such as viruses, bacteria, and fungi, so a syndromic approach can be required. In addition, since their rapid and accurate detection is very crucial, molecular diagnostics using cerebrospinal fluid is becoming the emerging standard method. METHODS: The study was conducted retrospectively to identify the incidence and distribution patterns of the pathogens according to gender, age, season, and month and to analyze their codetection from August 2017 to July 2020. It was also conducted to investigate turn-around times (TATs) according to the detection method. The detection methods were FilmArray® Meningitis/Encephalitis (M/E) method (FilmArray), Cepheid® Xpert EV assay (Xpert), and Multiplex PCR method for five species of bacteria. RESULTS: The overall incidence for at least one pathogen was 13.9% (346/2,496). The highest incidence was shown in age group 4 (3 - 6 years), with 27.4%. The detection rates by FilmArray, Xpert, and Multiplex PCR method were 39.8%, 41.7%, and 0.4%, respectively. Enterovirus (EV) showed the highest incidence rate, which accounted for 37.0%. The distribution of the pathogens according to the age groups were the highest in age group 4, with 47.5% (168/354), followed by 27.4% (97/354) in age group 5. Of the ten cases in which bacteria were detected, S. agalactiae accounted for 60.0% (6/10), most of which occurred in age group 1. E. coli K1, L. monocytogenes, and N. meningitidis were not detected. In the viral distribution, EV accounted for the highest proportion in all age groups. The overall proportion of EV accounted for 87.6% (310/354), followed by human parechovirus with 2.8% (10/354). The most commonly detected season was summer, comprising 75.1%. A total of eight cases of co-detection with two pathogens accounted for 1.6% (8/507) in FilmArray. In FilmArray, all TATs were found to be shorter than Xpert. CONCLUSIONS: The information on the incidence and distribution patterns of the pathogens causing CNS infections and their rapid detection are critically important to clinicians in the management of immunocompromised patients, elderly, and children. The expeditious molecular diagnostics for these pathogens would be valuable in medical decisions by clinicians.

BACKGROUND: Acute respiratory infection caused by respiratory microorganisms including various kinds of viruses and bacteria is the most common infectious disease. When managing patients, it is crucial to detect these microorganisms rapidly and monitor their occurrence and tendency. Recently, the methods of detecting them have been implemented by molecular diagnostics. The authors intended to investigate their incidence and distribution and identify the significance of the molecular diagnosis for their detection. METHODS: The retrospective study was conducted to investigate the incidence and distribution of respiratory microorganisms according to the age, gender, month, season, and the detection method and to analyze their co-infections from July 2016 to December 2019. In addition, the four types of turn-around time (TAT) for each detec-tion method were also analyzed. RESULTS: The overall incidence for at least one respiratory microorganism was 23.1% (3,645/15,808). The highest incidence was identified in age group 2 (1 - 3 months), 38.5%. The incidence rates by multiplex PCR using Anyplex and Allplex, FilmArray method, and influenza virus (flu) antigen detection test were 44.2% (718/1,625), 63.1% (1,198/1,899), and 14.1% (1,729/12,284), respectively. The overall incidence between male and female patients showed no statistically significant difference (p = 0.980), except for the flu antigen detection test (p = 0.000). Influenza A viruses (flu A) accounted for the highest percentage (34.9%), followed by rhinovirus/enterovirus (20.5%), RSV (12.8%), flu B (8.3%), and adenovirus (7.6%). These microorganisms showed characteristic distribution patterns according to season and month. Flu A and flu B predominated in winter and accounted for an increasing proportion as age increased according to the age groups. The overall co-infection rate was 22.5% (432/1,916). The average TATs of the FilmArray method were significantly much faster than multiplex PCR using Anyplex and Allplex (p = 0.000). CONCLUSIONS: The information on the incidence and distribution of respiratory microorganisms and their expeditious detection are considered critical to the management of the elderly, immunocompromised patients, and children. The rapid molecular-based diagnosis of respiratory infections would be beneficial in medical decision and prevention of their propagation.

PURPOSE: This study aimed to evaluate patellar tendon loading profiles (loading index, based on loading peak, loading impulse, and loading rate) of rehabilitation exercises to develop clinical guidelines to incrementally increase the rate and magnitude of patellar tendon loading during rehabilitation. METHODS: Twenty healthy adults (10 females/10 males, 25.9 ± 5.7 yr) performed 35 rehabilitation exercises, including different variations of squats, lunge, jumps, hops, landings, running, and sports specific tasks. Kinematic and kinetic data were collected, and a patellar tendon loading index was determined for each exercise using a weighted sum of loading peak, loading rate, and cumulative loading impulse. Then the exercises were ranked, according to the loading index, into tier 1 (loading index ≤0.33), tier 2 (0.33 < loading index <0.66), and tier 3 (loading index ≥0.66). RESULTS: The single-leg decline squat showed the highest loading index (0.747). Other tier 3 exercises included single-leg forward hop (0.666), single-leg countermovement jump (0.711), and running cut (0.725). The Spanish squat was categorized as a tier 2 exercise (0.563), as was running (0.612), double-leg countermovement jump (0.610), single-leg drop vertical jump (0.599), single-leg full squat (0.580), double-leg drop vertical jump (0.563), lunge (0.471), double-leg full squat (0.428), single-leg 60° squat (0.411), and Bulgarian squat (0.406). Tier 1 exercises included 20 cm step up (0.187), 20 cm step down (0.288), 30 cm step up (0.321), and double-leg 60° squat (0.224). CONCLUSIONS: Three patellar tendon loading tiers were established based on a combination of loading peak, loading impulse, and loading rate. Clinicians may use these loading tiers as a guide to progressively increase patellar tendon loading during the rehabilitation of patients with patellar tendon disorders and after anterior cruciate ligament reconstruction using the bone-patellar tendon-bone graft.

The authors attempted a possibility of unification in the educational curricula of both Oriental and Western medical schools for the unification of two medicines. Historically the two medicines were originated from the most primitive state like instinctive method and we can say two medicines were entirely the same. However, after abrupt and current development of science in the 19th century by discovery of microscope and bacteria as well as cells, changed medicine into recent unbelievable current medicine from old ancient style medicine like Chinese Medicine which was just the remnant old medicine. The unification of educational curricula is thought to be possible to combine each other by technical adjustment from mutual understanding and cooperation for the most high quality of peoples lives. There were good equality to partial correspondences between two educational curricula around 90% at two pre-and schools from the study to analyse. The combined medicine is thought to be more efficient to the diagnosis and treatment of patients because of the effectiveness of Oriental medicine in certain disease conditions like chronic illness by acupuncture as a alternative medicine or herbs.

In Korea the system of medical management has been bifurcated into two parts since the restoration of nation from Japanese after World War II. One is 'Western Medicine' and the other is 'Oriental Medicine' like Chinese but not like Japanese. The authors attempted to study on the unification of both medicines to prevent the confusion of medicare for people. The major part of medical care is accomplished by Western medicine among people in Korea and China. However, Oriental medicine is still present as well as college of Oriental medicine in small number. There have been long struggles between two parts of medicine because of each assertions for the theories. The ancient medicine has been likely to have its characteristics either in Western or Oriental medicine although in many countries were succeeded by Western medicine except a few Asian countries such as Korea and China. In Japan since the license of Oriental(herb) medicine was ceased about one hundred years ago, the Western medicine has been authorized by law until today and the herb is the secondary medicine as a kind of folk treatment as well as continuous and enormous study for scientification. In only China and Korea this herb medicine has been kept to use as a part of medicine by law though China has developed combined medicine to use both Western and Oriental medicine by one physician since previous prime minister Chou En-Lai around the year 1950 who made a recommendation to the two medical societies, Western and Oriental. This fact has a big sense to establish the unification of two medicines in near future in Korea as well as China. For this accomplishment of medical unification both parts of medicine require sincere and enormous efforts to study the theory and practice of herb medicine even from now on. This unification of two medicines will provide the best medicare in most convenient way to the people in the world creating new world medicine like the third medicine including alternative medicine. The acupuncture is changing to a new method in Western medicine especially applying into anesthesia and pain clinic in even USA and Western countries at this time. In conclusion the unification of the Western and Oriental medicine will provide the most reasonable and practical medicare including alternative medicine to people in the world. Because the Oriental medicine will be used at least separately to supplement the Western medicine by one physician.

OBJECTIVE: Increased intake of dietary fiber reduces the risk of obesity and type 2 diabetes. We assessed the effects of a fiber-rich diet on body weight, adipokine concentrations, and the metabolism of glucose and lipids in non-obese and obese subjects in Korea, where rice is the main source of dietary carbohydrates. RESEARCH METHODS AND PROCEDURES: Eleven healthy, non-obese and 10 obese subjects completed two 4-week phases of individual isoenergetic food intake. During the control diet phase, subjects consumed standard rice; during the modified diet phase, subjects consumed equal proportions of fiber-rich Goami No. 2 rice and standard rice. We used a randomized, controlled, crossover study design with a washout period of 6 weeks between the two phases. RESULTS: After the modified diet phase, body weight was significantly lower in both the non-obese and obese subjects (non-obese, 57.0 +/- 2.9 vs. 56.1 +/- 2.8 kg, p = 0.001; obese, 67.7 +/- 2.1 vs. 65.7 +/- 2.0 kg, p < 0.001 for before vs. after). The BMI was significantly lower in obese subjects (26.9 +/- 0.5 vs. 26.0 +/- 0.6 kg/m2, p < 0.001). The modified diet was associated with lower serum triacylglycerol (p < 0.01), total cholesterol (p < 0.01), low-density lipoprotein cholesterol (p < 0.05), and C-peptide (p < 0.05) concentrations in the obese subjects. DISCUSSION: These results indicate that fiber-rich Goami No. 2 rice has beneficial effects and may be therapeutically useful for obese subjects.

Fragile X syndrome is one of the most common forms of inherited mental retardation and is caused by the expansion of the CGG trinucleotide repeats in the FMR-1 gene. This study was aimed to facilitate the molecular screening of fragile X syndrome in Korean children with mental retardation of unknown etiology. The subjects were tested by Expand Long Template PCR system in the presence of 7-deaza-dGTP, and then by Southern blot analysis. The PCR method provided rapid and reliable results for the identification of fragile X negative and positive patients. One hundred one mentally retarded children (78 males and 23 females) were screened by PCR amplification, which detected only one abnormal sample. The PCR-positive case was confirmed by the CGG repeat expansion on Southern blot analysis with a positive cytogenetic result. In conclusion, Expand Long Template PCR may be used as the first screening test for detecting the fragile X syndrome.
