Objectives: This community-based cohort study was performed to investigate the incidence of and factors related to self-reported fragility fractures among middle-aged and elderly women living in rural Korea. Methods: The osteoporosis cohort recruited 430 women 40 to 69 years old in 1999, and 396 of these women were followed over 11 years. In 1999, questionnaires from all participants assessed general characteristics, medical history, lifestyle, menstrual and reproductive characteristics, and bone mineral density. In 2010, self-reported fractures and the date, site, and cause of these fractures were recorded. Cox proportional hazards models were used to calculate hazard ratios (HRs). Results: Seventy-six participants among 3949.7 person-years experienced fragility fractures during the 11-year follow-up. The incidence of fragility fractures was 1924.2 per 100 000 person-years (95% confidence interval [CI], 1491.6 to 2356.8). In the multivariate model, low body mass index (HR, 2.66; 95% CI, 1.13 to 6.24), a parental history of osteoporosis (HR, 2.03; 95% CI, 1.18 to 3.49), and postmenopausal status (HR, 3.50; 95% CI, 1.05 to 11.67) were significantly related to fragility fracture. Conclusions: Fracture prevention programs are needed among postmenopausal, rural, Korean women with a low body mass index and parental history of osteoporosis Korea.
Objectives : A human being is classified into 4 constitutions(Taeyangin, Soyangin, Taeumin, and Souemin) and each constitution has the different incidence, treatment and prevention of disease in Sasang Constutional Medicine[SCM], The purpose of this study is to find relative risk(RR)s of each risk factors including Sasang Constitution[SC] for incidence of ischemic stroke. Methods : In 344-case patients with ischemic stroke and 1446 healthy control subjects without ischemic stroke, we evaluated sex, age. height, weight, BMI, ECG abnormality, hypertension, diabetes mellitus, blood lipid level and SC. These data were statistically analysed to investigate the relations between risk factors and the incidence of ischemic stroke by chi-square test. And then significant factors were analysed to get each adjusted odds ratio[OR] by binary logistic regression analysis. Results : ECG abnormality, hypertension, diabetes mellitus, HDL(high density lipoprotein) cholesterol, and SC were significantly related to the incidence of ischemic stroke, while age, sex and BMI were adjusted in a binary logistic regression analysis. Especially in SC, the incidence of ischemic stoke in Tae-eumin and Soyangin were higher than that in Soeumin (Tae-eumin OR=11.68[95% CI: 6.26-21.80], Soyangin OR=4.64[95% CI: 2.66-8.10]). Conclusions : These results suggested that SC may be one of important risk factors for ischemic stroke and it should be a useful data for prediction of incidence of ischemic stroke.
Lampung is a malaria-endemic region in Indonesia with an annual parasite incidence of 0.06 per 1,000 population. The socio-demographic factors, clinical conditions, and artemisinin combination therapy (ACT) types might affect parasite clearance and parasite density. This study aims to investigate factors that influence parasite clearance and parasite density in malaria patients. A retrospective analytic observational and a cross-sectional approach was used to conduct this study. A total of 66 malaria patients were examined to investigate parasite density and clearance, socio-demographic profiles, clinical conditions, and ACT types. To analyze data, univariate, bivariate, and multivariate tests were used. Age (P=0.045; r=0.238) and ACT type (P=0.021; r=0.273) were the only variables that had a significant correlation with parasite clearance. Age (P=0.003; r=0.345) had a significant correlation with parasite density. The most influential factors related to parasite clearance were the ACT type (dihydroartemisinin piperaquine) (P=0.017; odds ratio (OR) 0.109; 95.0% confidence interval (CI), 0.018-0.675) and age (P=0.030; OR 0.132; 95.0% CI, 0.021-0.823). Age (P=0.046; OR 0.320; 0.105-0.978, 95.0% CI) was the most significant variable associated with parasite density.
There have been growing interests in olive oil, which is attributed to the beneficial health effects of the Mediterranean diet. Numerous studies suggest that oleic acid, the major fatty acid in olive oil, may contribute to less incidence of coronary heart disease(CHD) in the Mediterranean area. Although the major effects of high monounsaturated fatty acid(MUFA) consumption on lowered plasma cholesterol are generally attributed to the consequential replacement of saturated fatty acid in diets, some studies have shown a modest cholesterol lowering effect of MUFA alone when it replaces dietary carbohydrate at an equal amount of energy. Furthermore, MUFA increases the level of the protective high-density lipoprotein cholesterol more than polyunsaturated fatty acid(PUFA) does when these two classes of fatty acids replace carbohydrates in the diet. It has been generally recommended that optimal dietary fat should be rich in MUFA, such as oleic acid, low in saturated fatty acids and provide adequate amounts of PUFA. However, no conclusive observations have been made yet mainly due to a difficulty in controlling the proportion of oleic acid without adjusting the levels of the other fatty acids to be constant, which could also affect plasma cholesterol levels. Recent findings also suggest that dietary PUFA results in higher tendency toward lipid peroxidation whereas with MUFA the susceptibility of low density lipoprotein to oxidative stress is reduced. More studies are needed to clarify the effects of MUFA on reducing the incidence of CHD.
The potential therapeutic action of shikonin in an experimental model of rheumatoid arthritis (RA) was investigated. As a RA animal model, DBA/1J mice were immunized two times with type II collagen. After the second collagen immunization, mice were orally administered shikonin (2 mg/kg) once a day for 35 days, and the incidence, clinical score, bone mineral density (BMD), bone mineral content (BMC) and joint histopathology were evaluated. BMD in the proximal regions of the tibia largely increased in the shikonin treatment group compared with the control group. We also examined the effect of shikonin on inflammatory cytokines and cartilage protection. Shikonin treatment significantly reduced the incidence and severity of collagen-induced arthritis (CIA), markedly abrogating joint swelling and cartilage destruction. Shikonin also significantly inhibited the production of matrix metalloproteinase (MMP)-1 and up-regulated tissue inhibitors of metalloproteinase (TIMP)-1 in mice with CIA. In conclusion, shikonin exerted therapeutic effects through regulation of MMP/TIMP; these results suggest that shikonin is an outstanding candidate as a cartilage protective medicine for RA.
It is well defined that osteoporosis is an age related disorder and associated with decreased bone mass. It is one of the most important disease lacing the aging population because of its association with fracture of the hip, vertebrae and distal radius. The disease provoke a significant economic burden and major public health problem of an elderly. The life-time risk of hip fracture in white women is approximately 15% which is equal to the combined risk of breast, uterine, and ovarian cancer. Despite its deleterious effect on women's health, knowledge of the epidemiology of osteoporosis in Korea is only beginning. 1970 in Korea has non as the crossover period between the chronic and an Infectious diseases. As the result, the infant mortality declined and an elderly population in Korea increased significantly in the past decade, The average life expectancy of women in Korea is now about 75 years. Thus, the majority of Korean women will spend approximately one-third of their life in the postmenopause state. Therefore, better understanding of bone metabolism and fracture incidence in Korean population is a great interest for the medical community as well as for public health. Currently, no population based epidemiologic data are available to support the incidence of osteoporotic fractures in Korea. However, available data suggest that significant declining of bone mineral density (BMD [g/$cm^2$]) has been occurring in Korean women after menopause. In same population, peak BMD was observed around 33-39 years of age and continue to decline thereafter. An accelerated bone losses occur after the menopause and the average loss is approximately 13% within 15 years from the menopause. The incidence of fracture was highly correlated with an age and bone mineral density. The mean age of menopause in Korean women was 47 years and this age appears to getting younger when analyzed by the birth cohort. An earlier menopausal age and increase life expectancy place Korean women at increase risk for osteoporosis and bone fracture. Korean or Asian women are no longer protected from the risk of bone fracture. Therefore, an early prevention or intervention schemes are essential before the outbreak of osteoporosis and/or fracture occurs in Korean or Asian women.
Background: This systematic review and meta-analysis aimed to evaluate the efficacy and cardiovascular safety of romosozumab compared with placebo. Methods: Randomized controlled trials (RCTs) were searched from Medline, EMBASE, Cochrane Central, and Web of Science until July 2022. Primary outcomes included the change in bone mineral density (BMD) from baseline at month 6. The secondary outcomes were the change of bone turnover markers (N-terminal propeptide of type 1 procollagen (P1NP); C-terminal telopeptide of type 1 collagen (CTX)) from baseline at month 3, and the incidence of cardiovascular adverse events for the total follow-up period. Results: A total of 7 RCTs on 8,370patients were included. Romosozumab showed better effects in improving BMD in both lumbar spine and femoral neck at month 6 (standardized mean difference, SMD 2.20 [95% CI: 1.89-2.52], SMD 0.63 [95% CI: 0.41-0.86]). In contrast to placebo, romosozumab significantly increased PINP levels and reduced CTX levels at month 3 (SMD 0.93 [95% CI: 0.65-1.22], SMD -1.03 [95% CI: -1.23~ -0.82]. However, there was no significant difference in the composite incidence of cardiovascular adverse events and major adverse cardiovascular events (OR 1.16 [95% CI: 0.82-1.65], OR 1.08 [95% CI: 0.75-1.56]). Conclusion: This analysis showed that romosozumab significantly improved BMD compared to placebo and was beneficial for change in bone turnover markers. There is no significant difference in the incidence of cardiovascular adverse events compared to placebo.
Physoderma fungal species cause faba bean gall (FBG) which devastates faba bean (Vicia faba L.) in the Ethiopian highlands. In three regions (Amahara, Oromia, and Tigray), the relative importance, distribution, intensity, and association with factors affecting FBG damage were assessed for the 2019 (283 fields) and 2020 (716 fields) main cropping seasons. A logistic regression model was used to associate biophysical factors with FBG incidence and severity. Amhara region has the highest prevalence of FBG (95.7%), followed by Tigray (83.3%), and the Oromia region (54%). Maximum FBG incidence (78.1%) and severity (32.8%) were recorded from Amhara and Tigray areas, respectively. The chocolate spot was most prevalent in West Shewa, Finfinne Special Zone, and North Shewa of the Oromia region. Ascochyta blight was found prevalent in North Shewa, West Shewa, Southwest Shewa of Oromia, and the South Gondar of Amhara. Faba bean rust was detected in all zones except for the South Gonder and North Shewa, and root rot disease was detected in all zones except South Gonder, South Wollo, and North Shewa of Amahara. Crop growth stage, cropping system, altitude, weed density, and fungicide, were all found to affect the incidence and severity of the FBG. Podding and maturity stage, mono-cropping, altitude (>2,400), high weed density, and non-fungicide were found associated with increased disease intensities. However, crop rotation, low weed infestation, and fungicide usage were identified as potential management options to reduce FBG disease.
This study was conducted to determine the effective environmental control measures in preventing calf diarrheal disease in farms. It was found that the high numbers of calves in a cow house was directly related with the high incidence rate of diarrheal diseases. When the number of calves was increased in a cow house, it was difficult to reduce the diarrheal diseases of calves. It was revealed that the incidence rates of calf diarrheal disease were dramatically reduced when the delivery house which faced south. The periodical changes of bedding materials seemed beneficial good to control the possible resident infectious agents, including pathogenic viruses and bacteria. The control of the delivery time was important for reduction of calf diarrhea. It was revealed that September and October were the best time as the delivery period. In order to use old cow house as a delivery house, it should be sterilized by the disinfectant and the flame. When the diarrheal feces were removed as soon as possible, the transmission of diarrheal diseases among calves In the same house was reduced. When the diarrheal feces were not disposed, the incidence rate of diarrhea reached up to 50%. When the morbid calves were not quarantined, the incidence rate of diarrhea was 100%. In contrast, when the diseased calves were quarantined from other calves, the incidence rate of diarrhea was reduced, remarkably. The mean recovery time from the diarrhea of the treated calves in the southern cow house was much faster than that in the north cow house. The treatment of calves in a clean and well-ventilated cow house with dry bedding was more effective than that in a cold, wet, and dark house. It could be postulated that the most important environmental factor in the reduction of diarrheal diseases of calves is the blocking of the entry of the infectious agents. The complete sanitation and control of the delivery house in the using farm is more important than building a new cow house, for prevention of calf diarrheal diseases.
The purpose of this study was to evaluate the incidence and radiographic features of 677 cases of hypercementosis by means of the analysis of full mouth periapical radiograms in 4,236 persons visited the Department of Oral Radiology, School of Dentistry, Kyung Hee University during January 1984 to December 1989. The obtained results were as follows: 1. The incidence of hypercementosis was revealed to be 8.2% in total examined persons, and there was a higher incidence in females (9.4%) than in males (7.1%). 2. The hypercementosis was most frequently occurred in the 6th decades (29.2%), and the incidence was increased by advancing age until 6th decades. 3. There was a higher incidence in the maxilla (59.5%) than in the mandible (40.5%), and maxillary second premolar (18.5%) was the most frequently involved tooth. The maxillary first premolar (11.7%) was next in order to frequency followed by maxillary canine (10.0%) and mandibular first and second premolars (9.6%). 4. In the etiologic factors, 35.0% were inflammation, 31.2% were elongation, 6.2% were trauma from occlusion, 0.1 % were uneruption, and 27.5% were unknown. 5. In the degree of cementum apposition, 35.3% were Type Ⅰ, 29.5% were Type Ⅱ, and 35.2% were Type Ⅲ. 6. In the status of cementum apposition, 3.2% were mesial side, 8.9% were distal side, and 87.9% were mesial & distal side. 7. In the identification of radiographic density between normal cementum and excessive cementum, 12.7% could be identified, and 87.3% could be unidentified.
