Purpose@#We investigated the prognostic value of maximum tumor dissemination (Dmax), the distance between malignant lesions that were farthest apart, as assessed by fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT), and other clinical factors in patients with diffuse large B-cell lymphoma (DLBCL).We investigated the prognostic value of maximum tumor dissemination (Dmax), the distance between malignant lesions that were farthest apart, as assessed by fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT), and other clinical factors in patients with diffuse large B-cell lymphoma (DLBCL). @*Methods@#Patients who underwent FDG PET/CT for initial staging and treatment response evaluation of DLBCL were reviewed retrospectively. Baseline Dmax, maximum standardized uptake value, total summation of all metabolic tumor volumes (tMTV), and total summation of all total lesion glycolysis (tTLG) were measured. The treatment response was evaluated at the interim and end of first-line treatment (EOT) using the Deauville score (DS). FDG PET/CT parameters and other clinical factors including sex, age, serum lactate dehydrogenase (LDH) level, stage, performance status, and the International Prognostic Index (IPI) were analyzed to identify factors prognostic of the time to progression (TTP) and disease-specific survival (DSS). @*Results@#A total of 63 patients were included. Univariate survival analysis identified Dmax (> 275 mm), tMTV (> 180 mL), tTLG (> 1300), interim DS (≥ 4), and EOT DS (≥ 4) as significant predictors of poor TTP. Serum LDH level (> 640 IU/L), IPI (≥ 4), tMTV (> 180 mL), tTLG (> 1300), interim DS (≥ 4), and EOT DS (≥ 4) were significant predictors of DSS. After multivariate survival analysis, Dmax (P = 0.008) and EOT DS (P = 0.005) were independent predictors of TTP. EOT DS was an independent predictor of DSS (P = 0.029). @*Conclusions@#Dmax at the time of diagnosis and the EOT response assessed by FDG PET/CT provide useful prognostic information additive to the IPI in patients with DLBCL.

Objective@#Medication beliefs are a significant determinant of medication adherence in chronic illness. This study aimed to identify demographic, clinical, and medication-related factors associated with medication beliefs in patients with Parkinson’s disease (PD). @*Methods@#We used a descriptive cross-sectional design with a convenience sample of 173 PD patients who had been taking antiparkinson drugs for more than one year. @*Results@#The subjects who believed PD medication was more necessary had more severe illness, younger age of onset, longer illness duration, and longer duration of levodopa therapy. They had higher levels of non-motor symptoms and depression, number of medication uses, number of drugs, and levodopa equivalent dose, and they reported fluctuation of motor symptoms and dyskinesia. The subjects who used catechol-O-methyltransferase (COMT) inhibitors, dopamine agonists, amantadine, and monoamine oxidase-B (MAO-B) inhibitors had significantly higher necessity scores than those who did not use them. The subjects who had higher concerns about PD medications had higher levels of non-motor symptoms and depression. The subjects using amantadine and anticholinergics had significantly higher concern scores than those who did not use them. Positive necessity-concerns differentials were associated with severe illness, the presence of motor fluctuation and dyskinesia, and the use of COMT inhibitors. Based on stepwise multiple regression, the most significant factors influencing necessity beliefs were severe illness, followed by depression and motor fluctuation. @*Conclusion@#Severe illness, higher levels of depression, and motor fluctuation are independent factors influencing patients’ beliefs regarding medication necessity. Therefore, these characteristics should be considered in medication belief assessment and interventions for PD patients.

Objective:To determine the effect of Lentinula edodes extract on ultraviolet (UV) A and UVB-induced changes in matrix metalloproteinase (MMP) and typeⅠprocollagen expression using human immortalized HaCaT keratinocytes. Methods:Lentinula edodes ethanol extract (LEE) was obtained by extraction with 80% ethanol for 4 h at 80 ℃. Effect of LEE on UV-induced alteration on the expression and production of MMPs and typeⅠprocollagen in keratinocytes was investigated using ELISA, RT-PCR, and Western blotting assay. To determine the underlying mechanism of LEE-mediated effects, mitogen-activated protein kinase (MAPK) and activator protein 1 signaling pathways were analysed by Western blotting assay. Results:LEE significantly inhibited the expression of MMP-1 and MMP-9 and increased the expression of typeⅠprocollagen in UVA and UVB-irradiated HaCaT keratinocytes. The phosphorylation levels of p38 were significantly inhibited by LEE whereas it did not affect c-Jun N-terminal kinase and extracellular signal-regulated kinase phosphorylation. Suppression of p38 phosphorylation was also accompanied by downregulation of UVA and UVB-induced increase in c-Fos. Conclusions:LEE effectively inhibits the expression of MMP-1 and MMP-9 and increases typeⅠprocollagen production through the p38 MAPK/c-Fos signaling pathway in UVA and UVB-irradiated HaCaT keratinocytes. This findings suggest that Lentinula edodes may be developed as a cosmetic material to suppress UV exposure-mediated skin aging.

Maternal mortality is attracting attention worldwide, but maternal health problems after delivery have received less attention. Most studies focus on prenatal maternal health problems. We aimed to identify factors associated with postpartum health problems among married women of reproductive age in Democratic Republic of the Congo. We employed a cross-sectional study design and randomly enrolled 700 married women of reproductive age in Kenge city. Data collection instrument was developed using the UNICEF Multiple Indicator Cluster Survey. T-test, chi-square test, and binary logistic regression analysis were performed using the SPSS version 24.0. Significant risk factors associated with postpartum health problems were initial postnatal care period; within 24 hours (Odds Ratio [OR]=2.197, 95% confidence interval [CI]: [1.1564.174], p=.016); within 7 days (OR=1.972, 95% CI: [1.1023.528, p=.022]; within 14 days (OR=2.124, 95% CI: [1.0824.172], p=.029) among reproductive health and health service utilization characteristics. Health education by RECO (Relais Cmunataure) was associated with postpartum health problems including PCIME (Prise en Charge Integree des Maladies de l'Enfant; OR=1.845, 95% CI: [1.0383.282], p=.037); hand washing (OR=1.897, 95% CI: [1.0603.396], p=.031); malaria (OR=2.003, 95% CI: [1.1923.366], p=.009) among Maternal and Child Health intervention characteristics. In conclusion, it is necessary to develop and promote health policies and educational programs focusing on PNC service within 24 hours, PNC services within 7 days, PCIME, hand washing, prevention of malaria

Radioembolization using â¹â°Y microspheres (glass or resin) has been introduced as an effective intraarterial therapy for unresectable primary and metastatic liver cancers. Although the basic therapeutic effect of chemoembolization results from ischemia, the therapeutic efficacy of radioembolization comes from radiation. Furthermore, compared with surgical resection and local ablation therapy, radioembolization is available with less limitation on the sites or number of liver cancers. The radioisotope â¹â°Y is a β-radiation emitter without γ-radiation, with the emission of secondary bremsstrahlung photons and small numbers of positrons. Administration of â¹â°Y microspheres into the hepatic artery can deliver a high dose of radiation selectively to the target tumor with limited radiation exposure to the surrounding normal parenchyma, and has low systemic toxicity. In general, radioembolization has been considered for patients with unresectable primary or metastatic liver-only or liver-dominant cancers with no ascites or other clinical signs of liver failure, life expectancy of > 12 weeks, and good performance status. Here, we review the current radioactive compounds, pretreatment assessment, and indications for radioembolization in patients with hepatocellular carcinoma, intrahepatic cholangiocarcinoma, and liver metastases from colorectal cancer.

Planar scintigraphy using Tc-99mpertechnetate is useful for snapshot evaluation of hot thyroid nodules, which are pathologically follicular adenoma and seldom, if ever, malignant. The autonomy of the hot nodules has been demonstrated by the presence of thyroid-stimulating hormone-dependent extra-nodular thyroid tissue besides the hot nodules. Here, we present two cases of hot thyroid nodules in patients who underwent quantitative single-photon emission computed tomography/computed tomography (SPECT/CT). In addition to the nodules, contralateral normal thyroid parenchyma was evaluated based on standardized uptake values. One patient had a traditional follicular adenoma suppressing other thyroid tissue, whereas the other patient seemed to have a nodule erupting from underlying hyperfunctioning, not suppressed, thyroid tissue. This novel approach using quantitative SPECT/CT unveils a new pathology of hot thyroid nodule that does not suppress, but coincides with hyperfunctioning thyroid tissue.
Résumé
BACKGROUND: We investigated the hypothesis that pretreatment with nefopam 20 mg would influence the onset and recovery profiles of rocuronium-induced neuromuscular block. METHODS: After Institutional Review Board approval, 134 patients, aged between 20–65 years, belonging to the American Society of Anesthesiologists physical status classification I or II, were randomly allocated to receive either 0.9% normal saline (control group) or nefopam 20 mg (nefopam group), infused over one hour before induction of anesthesia. Anesthesia was induced with remifentanil and propofol, followed by endotracheal intubation with rocuronium 0.6 mg/kg. We recorded the lag time, onset time, clinical duration, recovery index, recovery time, and total recovery time. RESULTS: We included 111 patients in the final analysis. The lag time, onset time, clinical duration, recovery index, recovery time, and total recovery time of the nefopam group (n = 57) were not significantly different compared with that of the control group (n = 54). CONCLUSIONS: Pretreatment with nefopam 20 mg one hour before induction of anesthesia does not have a significant influence on the onset and recovery profiles of rocuronium-induced neuromuscular block.

OBJECTIVE: Quantitative parameters from Tc-99m pertechnetate single-photon emission computed tomography/computed tomography (SPECT/CT) are emerging as novel diagnostic markers for functional thyroid diseases. We intended to assess the utility of SPECT/CT parameters in patients with destructive thyroiditis. MATERIALS AND METHODS: Thirty-five destructive thyroiditis patients (7 males and 28 females; mean age, 47.3 ± 13.0 years) and 20 euthyroid patients (6 males and 14 females; mean age, 45.0 ± 14.8 years) who underwent Tc-99m pertechnetate quantitative SPECT/CT were retrospectively enrolled. Quantitative parameters from the SPECT/CT (%uptake, standardized uptake value [SUV], thyroid volume, and functional thyroid mass [SUVmean × thyroid volume]) and thyroid hormone levels were investigated to assess correlations and predict the prognosis for destructive thyroiditis. The occurrence of hypothyroidism was the outcome for prognosis. RESULTS: All the SPECT/CT quantitative parameters were significantly lower in the 35 destructive thyroiditis patients compared to the 20 euthyroid patients using the same SPECT/CT scanner and protocol (p < 0.001 for all parameters). T3 and free T4 did not correlate with any SPECT/CT parameters, but thyroid-stimulating hormone (TSH) significantly correlated with %uptake (p = 0.004), SUVmean (p < 0.001), SUVmax (p = 0.002), and functional thyroid mass (p < 0.001). Of the 35 destructive thyroiditis patients, 16 progressed to hypothyroidism. On univariate and multivariate analyses, only T3 levels were associated with the later occurrence of hypothyroidism (p = 0.002, exp(β) = 1.022, 95% confidence interval: 1.008 – 1.035). CONCLUSION: Novel quantitative SPECT/CT parameters could discriminate patients with destructive thyroiditis from euthyroid patients, suggesting the robustness of the quantitative SPECT/CT approach. However, disease progression of destructive thyroiditis could not be predicted using the parameters, as these only correlated with TSH, but not with T3, the sole predictor of the later occurrence of hypothyroidism.

BACKGROUND: The effect of dexamethasone injection on cisatracurium-induced neuromuscular block was compared according to different injection time points. METHODS: One hundred seventeen patients were randomly assigned to three groups: 8 mg of dexamethasone injected intravenously 2–3 h before anesthesia (group A), just before anesthesia induction (group B), and at the end of surgery (control group). Three minutes after anesthesia induction, intubation was performed without neuromuscular blockers, and acceleromyography was initiated. All patients received 0.05 mg/kg cisatracurium; the onset time and recovery profiles were recorded. RESULTS: Eighty patients were finally enrolled. The onset time (median [interquartile range], seconds) was significantly hastened in group A (520.0 [500.0–560.0], n = 30) compared to that in group B (562.5 [514.0–589.0], n = 22) (P = 0.008) and control group (586.5 [575.0–642.5], n = 28) (P < 0.001). The onset time in group B was faster than the control group (P = 0.015). The recovery time [mean (95% CI) minutes] was significantly hastened in group A [28.5 (27.3–29.6)] compared to that in group B [32.3 (31.0–33.6)] (P < 0.001) and control group [30.9 (29.9–31.8)] (P = 0.015). The total recovery time was significantly hastened more in group A [47.1 (45.5–48.6)] than group B [52.8 (51.6–54.0) minutes] (P < 0.001) and control group [50.5 (48.7–52.3) minutes] (P = 0.008). CONCLUSIONS: A single dose of 8 mg of dexamethasone hastened the onset and total recovery times of cisatracurium-induced block by approximately 15 and 9%, respectively if administered 2–3 h prior to surgery.

BACKGROUND: Few studies have investigated the effectiveness of intravenous fluid warmers at low and moderate flow rates below 1,000 ml/h. In this study, we compared the effectiveness of three different fluid warmers at a low flow rate (440 ml/h). METHODS: We experimentally investigated the fluid warming performances of Mega Acer Kit® (Group M, n = 10), Ranger™ (Group R, n = 10), and ThermoSens® (Group T, n = 10) at 440 ml/h for 60 min. All devices were set at a warming temperature of 41℃ with preheating for 10 min. Intravenous fluids were then delivered through them. The fluid temperature (primary endpoint) was measured at 76 cm from the device after infusion for 60 min. The expected decrease in mean body temperature (secondary endpoint) after 5 h infusion for a 70 kg patient (ΔMBT5) was also calculated. RESULTS: The fluid temperature (mean [95% CI]) at 76 cm from the device, 60 minutes after the infusion was higher in group M (36.01 [35.73–36.29]℃), compared to groups T (29.81 [29.38–30.24]℃) and R (29.12 [28.52–29.72]℃) (P < 0.001). The ΔMBT5 (mean [95% CI]) was significantly smaller in group M (−0.04 [−0.04 to −0.03]℃) than that in groups T (−0.27 [−0.28 to −0.29]℃; P < 0.001) and R (−0.30 [−0.32 to −0.27]℃; P < 0.001). However, none of the fluid warmers provided a constant normothermic temperature above 36.5℃. CONCLUSIONS: Mega Acer Kit® was more effective in warming the intravenous fluid with the smallest expected change in the mean body temperature, compared to Ranger™ and ThermoSens®, at a flow rate of 440 ml/h.

OBJECTIVE: Since Graves' disease (GD) is resistant to antithyroid drugs (ATDs), an accurate quantitative thyroid function measurement is required for the prediction of early responses to ATD. Quantitative parameters derived from the novel technology, single-photon emission computed tomography/computed tomography (SPECT/CT), were investigated for the prediction of achievement of euthyroidism after methimazole (MMI) treatment in GD. MATERIALS AND METHODS: A total of 36 GD patients (10 males, 26 females; mean age, 45.3 ± 13.8 years) were enrolled for this study, from April 2015 to January 2016. They underwent quantitative thyroid SPECT/CT 20 minutes post-injection of (99m)Tc-pertechnetate (5 mCi). Association between the time to biochemical euthyroidism after MMI treatment and %uptake, standardized uptake value (SUV), functional thyroid mass (SUVmean × thyroid volume) from the SPECT/CT, and clinical/biochemical variables, were investigated. RESULTS: GD patients had a significantly greater %uptake (6.9 ± 6.4%) than historical control euthyroid patients (n = 20, 0.8 ± 0.5%, p < 0.001) from the same quantitative SPECT/CT protocol. Euthyroidism was achieved in 14 patients at 156 ± 62 days post-MMI treatment, but 22 patients had still not achieved euthyroidism by the last follow-up time-point (208 ± 80 days). In the univariate Cox regression analysis, the initial MMI dose (p = 0.014), %uptake (p = 0.015), and functional thyroid mass (p = 0.016) were significant predictors of euthyroidism in response to MMI treatment. However, only %uptake remained significant in a multivariate Cox regression analysis (p = 0.034). A %uptake cutoff of 5.0% dichotomized the faster responding versus the slower responding GD patients (p = 0.006). CONCLUSION: A novel parameter of thyroid %uptake from quantitative SPECT/CT is a predictive indicator of an early response to MMI in GD patients.

OBJECTIVE: To investigate the diagnostic performance of coronary computed tomography angiography (CCTA), stress dual-energy computed tomography perfusion (DE-CTP), stress perfusion single-photon emission computed tomography (SPECT), and the combinations of CCTA with myocardial perfusion imaging (CCTA + DE-CTP and CCTA + SPECT) for identifying coronary artery stenosis that causes myocardial hypoperfusion. Combined invasive coronary angiography (ICA) and stress perfusion cardiac magnetic resonance (SP-CMR) imaging are used as the reference standard. MATERIALS AND METHODS: We retrospectively reviewed the records of 25 patients with suspected coronary artery disease, who underwent CCTA, DE-CTP, SPECT, SP-CMR, and ICA. The reference standard was defined as ≥ 50% stenosis by ICA, with a corresponding myocardial hypoperfusion on SP-CMR. RESULTS: For per-vascular territory analysis, the sensitivities of CCTA, DE-CTP, SPECT, CCTA + DE-CTP, and CCTA + SPECT were 96, 96, 68, 93, and 68%, respectively, and specificities were 72, 75, 89, 85, and 94%, respectively. The areas under the receiver operating characteristic curve (AUCs) were 0.84 ± 0.05, 0.85 ± 0.05, 0.79 ± 0.06, 0.89 ± 0.04, and 0.81 ± 0.06, respectively. For per-patient analysis, the sensitivities of CCTA, DE-CTP, SPECT, CCTA + DE-CTP, and CCTA + SPECT were 100, 100, 89, 100, and 83%, respectively; the specificities were 14, 43, 57, 43, and 57%, respectively; and the AUCs were 0.57 ± 0.13, 0.71 ± 0.11, 0.73 ± 0.11, 0.71 ± 0.11, and 0.70 ± 0.11, respectively. CONCLUSION: The combination of CCTA and DE-CTP enhances specificity without a loss of sensitivity for detecting hemodynamically significant coronary artery stenosis, as defined by combined ICA and SP-CMR.

PURPOSE: The purpose of this study was to examine the depression and cognitive function of community-dwelling older adults. METHODS: 243 aged over 65 in Won-Ju in South Korea participated in this study. Data were collected from April to June 2013 through interviews. This study utilized the Geriatric Depression Scale Short Form, the Korean version of MMSE-DS (MMSE for Dementia Screening), and infirmity testing for basic health status. Descriptive statistics, χ2, t-test, ANOVA, Scheffé's test, and Pearson's correlation coefficient were used. RESULTS: 75.3% of the participants belonged to the depression group, and the prevalence of cognitive impairment was 17.3%. There were significant differences in depression and cognitive function according to gender, educational level, type of insurance, subjective health, frailty, and whether to be a client of home care service. The level of depression was significantly higher and the level of cognitive functions was significantly lower in older adults in home care services than in community-dwelling older adults. CONCLUSION: This study is meaningful in that it included older adults in home care services to provide information to develop effective prevention programs for improving cognitive functions. The results of this study can be used to develop future community prevention and intervention.

Edentulous patients with severe alveolar bone resorption have trouble with using traditional complete denture. In order to overcome these problems, implant-retained overdenture was developed. SFI-bar(R) system can save time and cost compared to other existing bar systems which need complicated laboratory procedures because it can be adjusted directly in a patient's mouth. A 55-year-old male, who had experienced a fractured lower old implant-retained overdenture, wanted a durable and painless denture. The fractured Locator(R) attachments were removed and edentulous mandible was restored with SFI-bar(R). A 77-year-old female with a medical history of the Parkinson's disease and severely absorbed alveolar bone of mandible, wanted to wear a retentive mandibular denture without pain. After placing two implants in front of mental foramen, two adaptors were connected to two implants and a tube bar was connected to the adaptors. A female part fitted to the bar was attached to the new denture. These clinical reports describe two-implant-retained overdenture using the SFI-bar(R) system in mandibular edentulous patients. Since the patients were satisfied esthetically and functionally during 2 years' observation, we would like to report cases.

PURPOSE: The purpose of this study was to assess the breast-specific gamma imaging (BSGI) in Breast Imaging Reporting and Data System (BI-RADS) 4 lesions on mammography and/or ultrasound. METHODS: We performed a retrospective review of 162 patients who underwent BSGI in BI-RADS 4 lesions on mammography and/or ultrasound. RESULTS: Of the 162 breast lesions, 66 were malignant tumors and 96 were benign tumors. Sensitivity and specificity of BSGI were 90.9% and 78.1%, and positive predictive value and negative predictive value were 74.1% and 92.6%. The sensitivity or specificity of mammography and ultrasound were 74.2% and 56.3% and 87.9% and 19.8%, respectively. The sensitivity and specificity of BSGI for breast lesions ≤1 cm were 88.0% and 86.8%, while the values of beast lesions >1 cm were 92.7% and 61.5%. The sensitivity or specificity of BSGI and mammography for patients with dense breasts were 92.0% and 81.3% and 72.0% and 50.0%, respectively. 26 patients showed neither a nodule nor microcalcification on ultrasound, but showed suspicious calcification on mammography. The sensitivity and specificity of BSGI with microcalcification only lesion were 75.0% and 94.4%. CONCLUSION: This study demonstrated that BSGI had shown high sensitivity and specificity, as well as positive and negative predictive values in BI-RADS 4 lesions on ultrasound and/or mammography. BSGI showed excellent results in dense breasts, in lesions that are less than 1 cm in size and lesions with suspicious microcalcification only.

En este estudio se examinó si el estrés mental crónico se asocia con el rendimiento académico en adolescentes coreanos. La muestra estuvo constituida por los 74.186 adolescentes de entre el 7 y el 12 ° grado (12-18 años) que participaron en la 8va encuesta en internet sobre Comportamiento de Riesgo en Jóvenes en 2012. Se utilizó el análisis de regresión logística multivariante para aclarar cómo el estrés crónico mental se relacionaba con el rendimiento académico después del ajuste por edad, índice de masa corporal, posición económica de la familia, el nivel de educación de los padres, la frecuencia de fumar, la frecuencia de ingesta de alcohol, y la frecuencia de la actividad física vigorosa y moderada y ejercicios de fuerza musculares. Para los varones, las personas con estrés mental crónico muy alto tenían menos probabilidades de lograr un rendimiento académico promedio o superior (odds ratio [OR] = 0.738, 95% intervalo de confianza [IC]: 0.629 a 0.867, p <0,001) que aquellos con muy estrés mental baja. Para las niñas, las que tenían estrés mental muy alto tenían menos probabilidades (OR = 0.668; IC del 95%: 0.521 - 0.857, p = 0.002), mientras que aquellas con estrés mental bajo tenían más probabilidades (OR IC = 1.324, 95%: 1.029 -1.704; p = 0.029) para tener un rendimiento promedio académico o superior, en comparación con las niñas con estrés muy bajo. Los grados (pruebas, exámenes de ingreso) fueron la principal causa de estrés mental crónico tanto en varones (51.7%) y niñas (54.,8%). Los varones y las niñas de la República de Corea de estrés mental crónico muy alto mostraron una disminución del rendimiento académico.
We examined whether chronic mental stress is associated with academic performance in Korean adolescents. Our sample consisted of the 74,186 adolescents between the 7th and 12th grades (aged 12-18 years) who participated in the 8th Korean Youth Risk Behavior Web-based Survey in 2012. We used multivariate logistic regression analysis to clarify how chronic mental stress was related to academic performance after adjustment for age, body mass index, family economic status, parents' education level, smoking frequency, alcohol intake frequency, and frequency of vigorous and moderate physical activity and muscular strength exercises. For boys, those with very high chronic mental stress were less likely to achieve average academic performance or higher (odds ratio [OR] = 0.738, 95% confidence interval [CI]: 0.629-0.867, p < 0.001) than were those with very low mental stress. For girls, those with very high mental stress were less likely (OR = 0.668, 95% CI: 0.521-0.857, p = 0.002), while those with low mental stress were more likely (OR = 1.324, 95% CI: 1.029-1.704; p = 0.029) to have average academic performance or hig-her, compared with girls with very low stress. Grades (tests, entrance examinations) were the primary cause of chronic mental stress in both boys (51.7%) and girls (54.8%). Republic of Korean boys and girls with very high chronic mental stress showed decreased academic performance.
