Screening and Quantification of Depression in Mild-to-Moderate Dementia Through the GDS Short Forms

Abstract

We evaluated the validity of the 1-, 4- and 15-item versions of the GDS in 51 patients affected by mild to moderate dementia, using the long form as standard. The following sensitivity and specificity values were obtained: 66% and 91% for GDS-1, 93% and 87% for GDS-4, 79% and 100% for GDS-15. GDS-15 also showed good agreement with GDS-30 in defining the severity of depression. These findings support the use of GDS-4 for the screening of depression and of GDS-15 for its severity assessment.

大黄甘草汤联合间断短时静脉-静脉血液滤过对重症急性胰腺炎患者细胞因子的影响

Objective To approach the treatment effect and mechanism of action of intermittent short time veno-venuous hemofiltration(ISVVH)and Rheum Glycyrrhiza Decoction in patients with severe acute pancreatitis(SAP).Methods One hundred and three SAP patients were randomly divided into 3 groups.Rheum Glyeyrrhiza uraleusis fisch Decoction group(A,n=25),ISVVH group(B,n=35)and ISVVH CO-Rheum Glyeyrrhiza uralensis fisch decoction group(C,n=43).A,B and C groups were all treated with conventional therapy.However.the patients in group A were added Rheum Glycyrrhiza uralensis fisch Decoction,the patients in group B added ISVVH while group C were raised ISVVH co-Rheum Glycyrrhiza uralensis fiach Decoction.Finally,we observed three groups of patients with heart rate(HR),respiration(R),blood pressure(BP),liver and kidney function;oxygenation index(PaO2/FiO2),oxygen saturation(SaO2);blood routine,plasma electrolytes,glucose and C-reactive protein;parallel APACHE Ⅱ score;measure level of TNF-α,IL-10 in patients blood serum when they were admitted to hospital,24,48,96 h after treatment respectively.Results After treated 24,48,96 h,C group compared to B group,B group compared to A group,there were significantly improvements in APACHE Ⅱ score(P < 0.05);TNF-alevel decreased(P < 0.05);IL-10 level increased(P < 0.05);three groups after treatment of acute lung injury, thoracic/abdominal effusion,intestinal paralysis/obstruction,sepsis and other complications improved significantly(P < 0.05).Conclusions ISVVH and glycyrrhiza decoction can regulate the liver and renal dysfunctions that followed SAP,raise physical conditions,improve the complications of patients with SAP.     

The evaluation of short fusion in idiopathic scoliosis

Background:

Selective thoracic fusion in type II curve has been recommended by King et al. since 1983. They suggested that care must be taken to use the vertebra that is neutral and stable so that the lower level of fusion is centered over the sacrum. Since then there has been the trend to do shorter and selective fusion of the major curve. This study was conducted to find out whether short posterior pedicle instrumentation alone could provide efficient correction and maintain trunk balance comparing to the anterior instrumentation.

Materials and Methods:

A prospective study was conducted during 2005-2007 on 39 consecutive cases with idiopathic scoliosis cases King 2 and 3 (Lenke 1A, 1B), 5C and miscellaneous. Only the major curve was instrumented unless both curves were equally rigid and of the same magnitude. The level of fusion was planned as the end vertebra (EVB) to EVB fusion, although minor adjustment was modified by the surgeons intraoperatively. The most common fusion levels in major thoracic curves were T6–T12, whereas the most common fusion levels in the thoraco-lumbar curves were T10–L3. Fusion was performed from the posterior only approach and the implants utilized were uniformly plate and pedicle screw system. All the patients were followed at least 2 years till skeletal maturity. The correction of the curve were assessed according to type of curve (lenke IA, IB and 5), severity of curve (less than 450, 450-890 and more than 900), age at surgery (14 or less and 15 or more) and number of the segment involved in instrumentation (fusion level less than curve, fusion level as of the curve and fusion more than the curve)

Results:

The average long-term curve correction for the thoracic was 40.4% in Lenke 1A, 52.2% in Lenke 1B and 56.3% in Lenke 5. The factors associated with poorer outcome were younger age at surgery (<11 years or Risser 0), fusion at wrong levels (shorter than the measured end vertebra) and rigid curve identified by bending study. However, all patients had significant improved trunk balance and coronal hump at the final assessment at maturity. Two patients underwent late extension fusion because of junctional scoliosis.

Conclusions:

With modern instrumentations, the EVB of the major curve can be used at the end of the instrumentation in most cases of idiopathic scoliosis. In those cases with either severe trunk shift, younger than 11 years old, or extreme rigid curve, an extension of one or more levels might be safer. In particular situations, the concept of centering the lowest vertebra over the sacrum should be adopted.
