Objectives: This study analyzed the associations of hypertension (HTN) with symptoms and diagnosis of depression by income level among Korean adults. Methods: This study was based on the 2010-2017 Korea National Health and Nutrition Examination Survey data; a total of 29 425 adults (aged 20 years or older) were analyzed. HTN was defined as a systolic blood pressure ≥140 mmHg, diastolic blood pressure ≥90 mmHg, or use of hypertensive medications. Depression symptoms were evaluated based on a questionnaire about depression-related symptoms. A depression diagnosis was defined based on questionnaire responses indicating that a participant had been diagnosed with depression. Household income was divided into higher or lower income ranges based on the median income of the participants. Multiple logistic regression analyses were performed to assess the associations between HTN and depression symptoms/diagnosis in the higher-income and lower-income groups. Results: In the higher-income group, the odds ratio (OR) for the association between HTN and depression symptoms was 1.15 (95% confidence interval [CI], 0.97 to 1.37), and the OR for the association between HTN and depression diagnosis was 1.41 (95% CI, 1.13 to 1.76). In the lower-income group, the OR for the association between HTN and depression symptoms was 1.18 (95% CI, 1.04 to 1.34), whereas the OR for the association between HTN and depression diagnosis was 0.82 (95% CI, 0.70 to 0.97). Conclusions The associations of HTN with symptoms and diagnosis of depression differed by income level.

Background: Postpartum depression (PPD) affects 10-15% of women worldwide, and screening is recommended by clinical guidelines. In Malaysia, nurses in maternal and child health (MCH) clinics provide postpartum care. Aim: To determine nurses’ level of knowledge, beliefs and practices regarding PPD and factors associated with screening practices. Methods: A cross-sectional study using universal sampling was conducted on nurses from seven government MCH clinics in Malaysia. Data was collected from March until April 2016 through a self-reported questionnaire. Univariate and multivariate analyses were performed to identify factors associated with having ever performed PPD screening. Results: Of the 108 nurses, 55.6% scored above the median total knowledge score (17 out of 24 points). Despite a high proportion of nurses believing that they were responsible for PPD screening (72.2%), counselling depressed mothers (72.2%) and referring mothers for further treatment (87.0%), only 64.8% and 51.9% were confident in recognizing PPD and counselling depressed mothers, respectively. Only 25.9% had ever practiced PPD screening, which was associated with beliefs concerning screening taking too much time (adjusted odds ratio [AOR]=0.13, 95% confidence interval [CI]= 0.02–0.74, P=0.022) and that screening is their responsibility (AOR=14.12, 95%CI=1.65-120.75, P=0.016). Conclusion: More than half of the nurses scored above the median total knowledge score and had positive beliefs towards PPD screening. However, PPD screening practices were poor, and this outcome was associated with their beliefs regarding time and responsibility.

The purpose of this study is to investigate the effect of the ball-cone contact interface variation on the ceramic ball stress which is the dominant factor of the design of the moldular artificial hip joint. A contact stress analysis problem is formulated using the optimization principle and finite element analysis technique on the ball-cone system of three dimensional axi-symmetrical model, Numerical procedure is employed to get the solution for varying angles of cones and angular mismatches between the ball and cone interfaces. There is a fair amount of friction in the interface and included in the analysis model.

Ischemic myelopathy is a rare and uncommon disease than the cerebral ischemia. Ischemia of spinal cord usually occur in the midthoracic regions (T4-T8). The major arteries supplying spinal cord are anterior and posterior spinal arteries. Anterior spinal artery is more responsible for the ischemic change of the spinal cord. We report a 45 years old man with ischemia of the spinal cord and acute renal failure due to rhabdomyolysis following the heavy alcohol ingestion.

Clear cell sarcoma of kidney(CCSK) is a rare pediatric neoplasm characterized by a predominating component of clear cells, a predilection for metastases to bone, and a poor prognosis. The incidence of CCSK peaks during the 2nd year of life and adult cases are very rare. We report a case of CCSK encountered in the right kidney of a 39-year-old man. Grossly, it was a lobulated mass showing infiltrative margin, measured 7x5.5x5cm and had a homogeneous gray-tan color with a soft, fish-flesh consistency. Microscopically, about half of the tumor revealed the classic pattern of CCSK, having tumor cell cords or nests separated by the characteristic alveolar capillary networks. The tumor cells had clear pale cytoplasm, bland looking round nuclei and inconspicuous nucleoli. The other half showed the epithelioid-trabecular pattern forming pseudorosette or cord-like structures. Immunohistochemically, there was only a focal positive reaction to vimentin. Ultrastructurally, the tumor cells showed the primitive nephrogenic mesenchymal differentiation such as electron lucent cytoplasm, a small amount of organelles, scanty heterochromatin, inconspicuous nucleoli, and a lack of flocculant basal lamina material around the cytoplasmic membrane. We consider that this is a case of CCSK occuring in the oldest patient ever reported, confirmed by both immunohistochemistry and electron microscopy.

OBJECTIVETo establish a reversed-phase high performance liquid chromatorgraphy (RP-HPLC) method for detecting the dencichine in Panax notoginseng extracts and drug preparations.

METHODDencichine was extracted with the borate buffer (pH 9. 18) and the clear supernatant was used for the derivatization. Pre-column derivatization was performed using 9-fluorenylmethyl chloroformate (FMOC) to form derivatives. The mobile phase consisted of methanol and 0. 05 mol x L( -1) NaH2 PO4 (48: 52) (pH adjusted to 7.4 with NaOH solution) in a flow rate of 1.0 mL m min(-1). The ultraviolet (UV) detection wavelength was set at 262 nm.

RESULTThe linearity was demonstrated over a wide range of concentration from 1.76 mg L(-1) to 352 mg x L(-1) for dencichine. The detection limit was determined to be 60 microg x L(-1). The derivative was stable and the derivatization agent did not influence the measurement of dencichine. The average recovery rate was 95. 3% and the relative standard derivation (RSD) was 1. 7%. The method was used to determine dencichine in different P. notoginseng extracts and drug preparations.

CONCLUSIONThis method is simple, fast and sensitive, suitable for determining the dencichine in P. notoginseng extracts and drug preparations as well as for the study of the dencichine metabolism in vivo.

PURPOSE: Since the publication of the 5th edition of the AJCC cancer staging manual in 1997 (old stage), significant developments have occurred in the field of breast cancer diagnosis and management; therefore, it was revised at 2002 (new stage). There are few reports comparing the changes in prognosis in relation to the changes in the staging system. The aims of this study were to evaluate the changes in patient distribution and prognosis according to the changes in the staging system and to elucidate the efficacy of new staging system. METHODS: The records of 1, 275 patients who underwent an operation for breast cancer at Yeung-Nam University Hospital between 1987 and 2003 were reviewed. The pathological stage was assigned retrospectively according to the 5th and the 6th AJCC staging criteria. The patient distributions by stage, nodal status, 5-year relapse free survival (RFSR) and overall survival rates (OSR) were retrospectively compared. RESULTS: Five hundred and five of 616 stage II patients according to the 1997 classification system were also stage II according to the 6th AJCC staging system. The number of patients with stages IIA and IIB decreased from 370 and 246 (old stage) to 342 and 165 (new stage), respectively. Conversely, the number of patients with stage III increased from 158 (old stage) to 271 (new stage). The five-year RFSR for patients with stage I, IIA, IIB, and IIIA were 94.2, 87.1, 74.3, and 48.8% according to the old stage (P<0.0001), and 95.2, 87.8, 81.7, and 66.8%, respectively, according to the new stage (P<0.0001). The five-year OSR for patients with stage I, IIA, IIB, and IIIA were 98.7, 94.3, 86.1, and 63.5% according to the old stage (P<0.0001), and 98.7, 95.7, 96.5, and 72.9%, respectively, according to the new stage (P<0.0001). The RFSR and OSR for stage IIIC were 42.0 and 59.5%, respectively. There was significant difference in the five-year OSR for stages IIB and IIIA (P=0.0308 and P=0.0132, respectively). CONCLUSION: In our study, the 6th AJCC staging system shifted poorer prognostic cohort of each stage toward a higher stage compared to the 1997 version. Therefore, the survival rate for any one stage assigned by 2002 staging system was also improved. In conclusion, it is imperative that careful attention is devoted to this effect so that accurate conclusions regarding the efficacy of new treatment can be drawn.

PURPOSE: The purpose of this study was to compare the effects of resiniferatoxin (RTX) and botulinum toxin (BTX) on the bladder detrusor function in a cyclophosphamide (CYP)-induced cystitis rat model. MATERIALS AND METHODS: Sprague-Dawley rats were divided into 5 groups (1: saline treated, 2: CYP and BTX treated, 3: CYP and RTX treated, 4 and 5: CYP treated and sham operated as the counterpart of groups 2 and 3, respectively, with normal saline). 100mg/kg CYP was injected every third day for five weeks. Cystometrograms were performed after the BTX and RTX treatments. RESULTS: 1. The normal control group and the CYP-treated only group. In the CYP-treated group, the time of micturition frequency, the maximal detrusor pressure on the cystometergram (Pvesmax at CMG), the maximal detrusor pressure on the pressure-flow study (Pvesmax at pr/flow) and the episodes of irregular contractions were increased. 2. The CYP-only group and the CYP/BTX or CYP/RTXtreated groups. In the CYP/BTX or CYP/RTX treated groups, the time of micturition frequency, the Pvesmax at CMG, the Pvesmax at pr/flow and the episode of irregular contractions were decreased. 3. The CYP/BTXtreated group and the CYP/ RTXtreated group. There was no statistically significant difference between the two groups regarding micturition frequency, the PvesMax at CMG and the PvesMax at pr/flow, the Dhfo and the episodes of involuntary contractions (p>0.05). CONCLUSIONS: Intravesical administration of BTX or RTX blocked the CYP-induced detrusor overactivity as was shown by the restoration of the micturition frequency, the intravesical pressure and the involuntary contraction episodes to a control level. There was no statistically significant difference between the two groups regarding the urodynamic parameters.
