Laparoscopic surgery is not inherently dangerous for patients presenting with benign gynaecologic pathology. Results of a meta-analysis.

BACKGROUND Laparoscopic surgery presents a large number of advantages over laparotomy. The goal of this work was to check whether these benefits outweigh any greater risk of complications. METHODS The study design was a meta-analysis of published data from prospective randomized clinical trials (RCT). For the period 1966 to June 2000 we searched Medline and Cochrane Controlled Trial Registers and asked the investigators for further details. Meta-analysis was carried out with the Cochrane review manager software RevMan 4.1. RESULTS A total of 27 prospective RCT including 3611 women (1809 treated by operative laparoscopy and 1802 treated by laparotomy) were enrolled in the meta-analysis. The overall risk of complications was significantly lower for patients operated by laparoscopic surgery [relative risk (RR) 0.59; 95% confidence interval (CI) 0.50-0.70]. There was no statistically significant difference concerning the risk of major complications with respect to the approach used (RR 1.0; 95% CI 0.60-1.65). The risk of minor complications was significantly lower for patients operated by laparoscopic surgery (RR 0.55; 95% CI 0.45-0.66). Concerning the risks of readmission, second procedure and blood transfusion, there was no difference between the two groups. Identical results were found when we performed a sensitivity analysis including or excluding studies according to the methodological score. Subgroup analysis according to how serious the surgery was (minor, major, advanced) showed a significant increase in the risk of transfusion for advanced procedures performed by laparotomy. CONCLUSIONS Laparoscopic surgery is not inherently dangerous for patients presenting benign gynaecological pathologies. The potential risk of complications should no longer be advanced as an argument against using laparoscopic surgery rather than laparotomy for an operation when the indication allows the choice.
Extension Study of Participants from the Trial of Early Aggressive Therapy in Juvenile Idiopathic Arthritis

Objective. To follow children with juvenile idiopathic arthritis (JIA) who had completed at least 6 months of the TRial of Early Aggressive Therapy (TREAT) clinical study for an additional 2 years, describing safety of early aggressive treatment, disease activity, function, and duration of clinical inactive disease (CID) during followup. Methods. Children were treated as per provider’s discretion. Physician, patient/parent, and laboratory measures of disease status as well as safety information were collected at clinic visits every 3 months for up to 2 years. Results. Forty-eight children were followed for a mean of 28 months (range 12–42) beyond the end of the TREAT study. Half of patients were in CID for > 50% of their followup time. Overall, 88% of patients achieved CID at > 1 study visit and 54% achieved clinical remission while taking medication. Six patients were in CID for the duration of the study, and, of those, 2 achieved a full year of clinical remission while not taking medication. Active disease was mild: mean physician’s global assessment 2.4, active joint count 3.5, parent global evaluation 2.4, Childhood Health Assessment Questionnaire 0.32, erythrocyte sedimentation rate 19 mm/h, and morning stiffness 23 min. There were no serious adverse events or adverse events reported at grade 3 or higher of Common Terminology Criteria for Adverse Events. Conclusion. Early aggressive therapy in this cohort of patients with polyarticular JIA who had high initial disease activity was associated with prolonged periods of CID in the majority of patients during followup. Those not in CID had low levels of disease activity.
Autonomic Dysfunction and Gastroparesis in Cirrhosis

Background Patients with cirrhosis of the liver frequently present with many gastrointestinal complaints that are most likely due to abnormal gastrointestinal motility. The cause of these motility disorders in cirrhotics is unknown, however, underlying autonomic dysfunction may play a role. Objective To determine the association between autonomic dysfunction and delayed gastric emptying in cirrhotic patients. Methods We prospectively studied 20 patients with cirrhosis of the liver and postprandial abdominal pain, nausea, and vomiting and 10 asymptomatic patients with Hepatitis C (HCV) and no evidence of cirrhosis. All patients underwent 5 standardized cardiovascular tests to assess autonomic function. Each test was scored on a continuum from 0 (normal) to 5 (severe disease), thus producing a composite score of 0 to 5 for each subject. A composite score of greater than 1.5 was considered abnormal, with 5 representing severe autonomic involvement. A solid phase gastric emptying study was performed in each patient and a gastric retention of greater than 50% at 100 minutes was considered abnormal. Results The mean percent retention at 100 minutes was 70.7% in the cirrhotic group vs. 26.1% (P < 0.001) in the patients with HCV and no evidence of cirrhosis (controls). The composite autonomic score for the cirrhotic group was 3.4 vs. 1.2 (P < 0.001) in the controls. Conclusions Our results suggest that gastroparesis is common in patients with cirrhosis of the liver, and may account for gastrointestinal symptoms of postprandial abdominal pain, nausea, and vomiting. The presence of autonomic dysfunction correlates positively with underlying motility disorders, such as delayed gastric emptying.
Prognostic significance of immune subset measurement in individuals with AIDS-associated Kaposi's sarcoma.

PURPOSE A prognostic index for AIDS-associated Kaposi's sarcoma (KS) diagnosed in the era of highly active antiretroviral therapy (HAART) was based on routine clinical and laboratory characteristics. Because immune subset measurement is often performed in HIV-positive individuals, we examined whether these were predictive of mortality independently of the prognostic index, or could predict time to progression of KS. PATIENTS AND METHODS We performed univariate and multivariate Cox regression analyses on a data set of 326 individuals with AIDS-associated KS to identify immune subset covariates predictive of overall survival and time to progression. Adaptive (CD8 T cell and CD19 B cell) and innate (CD16/56 natural-killer cell) immune parameters were studied by flow cytometry. RESULTS In univariate analyses, all three immune subsets had significant effects on overall survival (P < .025). In multivariate analyses including the prognostic index, only CD8 counts remained significant (P = .026), although its effect on the overall prognostic index is small. An increase of 100 cells/mm3 in the CD8 count confers a 5% improvement in overall survival. Individuals with a higher CD8 count did not have an increased time to progression. Patients who were already on HAART at the time of KS diagnosis did not have a shorter time to progression than those who were antiretroviral naïve at KS diagnosis. CONCLUSION The CD8 count appears to provide independent prognostic information in individuals with AIDS-associated KS. Measurement of the CD8 count is clinically useful in patients with KS.
Inhibition of the heat shock protein 90 molecular chaperone in vitro and in vivo by novel, synthetic, potent resorcinylic pyrazole/isoxazole amide analogues

Although the heat shock protein 90 (HSP90) inhibitor 17-allylamino-17-demethoxygeldanamycin (17-AAG) shows clinical promise, potential limitations encourage development of alternative chemotypes. We discovered the 3,4-diarylpyrazole resorcinol CCT018159 by high-throughput screening and used structure-based design to generate more potent pyrazole amide analogues, exemplified by VER-49009. Here, we describe the detailed biological properties of VER-49009 and the corresponding isoxazole VER-50589. X-ray crystallography showed a virtually identical HSP90 binding mode. However, the dissociation constant (Kd) of VER-50589 was 4.5 ± 2.2 nmol/L compared with 78.0 ± 10.4 nmol/L for VER-49009, attributable to higher enthalpy for VER-50589 binding. A competitive binding assay gave a lower IC50 of 21 ± 4 nmol/L for VER-50589 compared with 47 ± 9 nmol/L for VER-49009. Cellular uptake of VER-50589 was 4-fold greater than for VER-49009. Mean cellular antiproliferative GI50 values for VER-50589 and VER-49009 for a human cancer cell line panel were 78 ± 15 and 685 ± 119 nmol/L, respectively, showing a 9-fold potency gain for the isoxazole. Unlike 17-AAG, but as with CCT018159, cellular potency of these analogues was independent of NAD(P)H:quinone oxidoreductase 1/DT-diaphorase and P-glycoprotein expression. Consistent with HSP90 inhibition, VER-50589 and VER-49009 caused induction of HSP72 and HSP27 alongside depletion of client proteins, including C-RAF, B-RAF, and survivin, and the protein arginine methyltransferase PRMT5. Both caused cell cycle arrest and apoptosis. Extent and duration of pharmacodynamic changes in an orthotopic human ovarian carcinoma model confirmed the superiority of VER-50589 over VER-49009. VER-50589 accumulated in HCT116 human colon cancer xenografts at levels above the cellular GI50 for 24 h, resulting in 30% growth inhibition. The results indicate the therapeutic potential of the resorcinylic pyrazole/isoxazole amide analogues as HSP90 inhibitors. [Mol Cancer Ther 2007;6(4):1198–211]
Investigation of In Vitro Activity of Five Antifungal Drugs against Dermatophytes Species Isolated from Clinical Samples Using the E-Test Method.

OBJECTIVE Dermatomycosis is an infection with fungi related to the skin: glabrous skin, hair and/or nails. Oral treatment of fungal infections in dermatology has become a preferred modality for the management of these very common conditions. Although there are increasing numbers of antifungals available for treatment of dermatophytes, some cases and relapses have been unresponsive to treatment. The determination of fungus in-vitro antifungal susceptibility has been reported to be important for the ability to eradicate dermatophytes. It is necessary to perform antifungal susceptibility testing of dermatophytes. E-test (AB Biodisk, Sweden) is a rapid, easy-to-perform in-vitro antifungal susceptibility test. The aim of this study was to investigate the susceptibility of the different species of dermatophyte strains isolated clinical specimens to five antifungal agents using the E-test method. MATERIALS AND METHODS A total of 66 specimens were collected from the nails, feet, inguinal region, trunk and hands. These strains tested MIC endpoints of E-test for amphotericin B, fluconazole, itraconazole, caspofungin, and ketoconazole were read after 72, and 96 hours incubation for each strain on RPMI 1640 agar. RESULTS The dermatophytes tested included Trichophyton rubrum 43 (65.1%), Trichophyton mentagrophytes 7 (10.7%), Microsporum canis 5 (7.6%), Trichophyton tonsurans 5 (7.6%), Epidermophyton floccosum 4 (6.0%) and Trichophyton violaceum 2 (3.0%). The most active agent against all dermatophytes species was caspofungin with a minimal inhibitory concentration (MIC) range (μg/mL(-1)) (0.02-3, 0.032-4, 0.125-0.50, 0.032-2, 0.25-0.50, 0.125-0.50) and it raconazole with an MIC range (μg/mL(-1)) (0.038-1.5, 0.094-1.5, 1-32, 0.016-0.50, 0.25-0.50, 0.125-0.50). The least active agent was fluconazole with an MIC range (μg/mL(-1)) (0, 19-48, 2-256, 2-8, 256, 256, 8-24). CONCLUSION E-test seems to be an alternative method to MIC-determination of antifungal drugs for dermatophytes species, since it is a less-laborious methodology and results could be obtained faster.
Listening to Music Affects Diurnal Variation in Muscle Power Output

Abstract The purpose of this investigation was to assess the effects of listening to music while warming-up on the diurnal variations of power output during the Wingate test. 12 physical education students underwent four Wingate tests at 07:00 and 17:00 h, after 10 min of warm-up with and without listening to music. The warm-up consisted of 10 min of pedalling at a constant pace of 60 rpm against a light load of 1 kg. During the Wingate test, peak and mean power were measured. The main finding was that peak and mean power improved from morning to afternoon after no music warm-up (p<0.001 and p<0.01, respectively). These diurnal variations disappeared for mean power and persisted with an attenuated morning-evening difference (p<0.05) for peak power after music warm-up. Moreover, peak and mean power were significantly higher after music than no music warm-up during the two times of testing. Thus, as it is a legal method and an additional aid, music should be used during warm-up before performing activities requiring powerful lower limbs′ muscles contractions, especially in the morning competitive events.
Growth inhibitory effect of the Src inhibitor dasatinib in combination with anticancer agents on uterine cervical adenocarcinoma cells

Uterine cervical adenocarcinoma has a poor clinical prognosis when compared with squamous cell carcinoma. Therefore, the development of new treatment strategies for uterine cervical adenocarcinoma is necessary. Src is a proto-oncogene that is important in cancer progression. Dasatinib is a Src inhibitor that has been reported to be effective when used in combination with anticancer drugs. The present study aimed to confirm Src expression in human cervical adenocarcinoma cell lines and to determine the mechanism underlying the inhibitory effect of dasatinib on Src signaling in vitro. Western blot analysis was performed to investigate Src expression in cervical adenocarcinoma cell lines (HeLa and TCO-2 cells). The cells were cultured for 48 h with the addition of different concentrations of anticancer drugs (paclitaxel or oxaliplatin). Viable cell count was measured using a colorimetric (WST-1) assay. The concentrations of anticancer agents were fixed according to the results obtained, and the same experiments were performed using the drugs in combination with dasatinib at various concentrations to determine the concentrations that significantly affected the number of viable cells. The presence or absence of apoptosis was investigated using a caspase-3/7 assay. Signal transduction in each cell line was examined using western blotting. Src was activated in the two cell lines, and cell proliferation was significantly suppressed by each anticancer drug in combination with 10 µM dasatinib. Caspase-3/7 activity was also increased and Src signaling was suppressed by each anticancer drug in combination with dasatinib. In conclusion, Src is overexpressed in cervical adenocarcinoma cell lines, and dasatinib inhibits intracellular Src signaling and causes apoptosis. The results of the present study suggest that Src may be targeted in novel therapeutic strategies for cervical adenocarcinoma.
The reliability performance of copper wire bonding BGA package by way of HAST methodology

Cu wire bonding technology is increasingly being used for the various IC packages from consumer application to high-reliability electronic products due to cost reduction consideration as well as electrical and thermal performance improvement in comparison with Au wire bonding. Despite these positive impacts of the improvements, the reliability still needs to be correctly assessed by the industry in a quantitative manner due to uncertain materials and assembly process issue. In the study, multiple Cu wire types and wire bonding process conditions are designed to validate assembly integrity based on Lead free BGA package with 14×14 body size and 384 I/O. Two bonding wire manufacturers provide the copper wire and palladium coated copper wire used for evaluation. Green molding compound free of halogenated flame retardant with known chloride content is used to mold the BGA package. After process characterization is verified based on wire pull and bond shear test. A HAST methodology (Highly Accelerated Stress Test) is applied to validate the BGA package reliability for the understanding of corresponding materials interaction among the wire material, molding compound and bonding pad metallization due to the acceleration stress drive from the temperature and humidity and bias voltage. In this task, there are five HAST conditions executed including 130°C/85RH%, 130°C/55RH%, 110°C/85RH%, 120°C/60RH% and 85°C/85RH% under 5.5 volt bias. Various temperature and humidity represent relative stress factors to accelerate the test to fail, as well the 3 stress factors usually influence the ionic ingredient in the molding compound to react with Cu wire and pad metallization. There are 4 daisy chain loops designed to monitor electrical resistance after each time period set in one BGA package for the failure judgment when resistance is fully open. Base on the HAST result and following failure analysis, the effect of testing duration, temperature and humidity differences and mold compound type are discussed.
Role transitions and young adult maturing out of heavy drinking: evidence for larger effects of marriage among more severe premarriage problem drinkers.

BACKGROUND Research has shown a developmental process of "maturing out" of problem drinking beginning in young adulthood. Perhaps surprisingly, past studies suggest that young adult drinking reductions may be particularly pronounced among those exhibiting relatively severe forms of problem drinking earlier in emerging adulthood. This may occur because more severe problem drinkers experience stronger ameliorative effects of normative young adult role transitions like marriage. METHODS The hypothesis of stronger marriage effects among more severe problem drinkers was tested using 3 waves of data from a large ongoing study of familial alcohol disorder (N = 844; 51% children of alcoholics). RESULTS Longitudinal growth models characterized (i) the curvilinear trajectory of drinking quantity from ages 17 to 40, (ii) effects of marriage on altering this age-related trajectory, and (iii) moderation of this effect by premarriage problem drinking levels (alcohol consequences and dependence symptoms). Results confirmed the hypothesis that protective marriage effects on drinking quantity trajectories would be stronger among more severe premarriage problem drinkers. Supplemental analyses showed that results were robust to alternative construct operationalizations and modeling approaches. CONCLUSIONS Consistent with role incompatibility theory, findings support the view of role conflict as a key mechanism of role-driven behavior change, as greater problem drinking likely conflicts more with demands of roles like marriage. This is also consistent with the developmental psychopathology view of transitions and turning points. Role transitions among already low-severity drinkers may merely represent developmental continuity of a low-risk trajectory, whereas role transitions among higher-severity problem drinkers may represent developmentally discontinuous "turning points" that divert individuals from a higher- to a lower-risk trajectory. Practically, findings support the clinical relevance of role-related "maturing out processes" by suggesting that they often reflect natural recovery from clinically significant problem drinking. Thus, understanding these processes could help clarify the nature of pathological drinking and inform interventions.
Immediate Pars Plana Vitrectomy Improves Outcome in Retained Intravitreal Lens Fragments after Phacoemulsification

Purpose: To investigate the clinical features, visual acuity outcomes and the most appropriate intervention time in patients with retained lens fragments managed by pars plana vitrectomy. Methods: This was a retrospective review of the records of 78 patients who underwent pars plana vitrectomy for retained lens fragments at the Tri-Service General Hospital from January 1, 2000, to December 31, 2006. Results: The mean age of the patients was 70 years (range, 24–92 years). There were 40 men (51%) and 38 women (49%). The mean follow-up period after surgery was 13.8 months. Forty-five patients (58%) had vitrectomy within 1 day of phacoemulsification (group A), 22 (28%) within 1 week (group B) and 11 (14%) after more than 1 week (group C). No patients in group A developed complications, and 76% achieved a final visual acuity of 6/12 or better. In group B, all patients had elevated intraocular pressure, and 45% achieved a final visual acuity of 6/12 or better. In group C, all patients presented with corneal edema, moderate or severe uveitis, and elevated intraocular pressure. Of these patients, 27% had cystoid macular edema, 36% developed retinal detachment, and 27% had a final visual acuity of 6/12 or better. Conclusion: Pars plana vitrectomy performed immediately after cataract surgery for retained lens fragments is a viable option and may achieve a better visual outcome, with reduced risk of secondary glaucoma, retinal detachment or cystoid macular edema.
Communication-Efficient Distributed Demand Response: A Randomized ADMM Approach

In this paper, we consider the distributed demand response (DDR) problem for achieving the real-time power balance in a neighborhood with a large number of load customers and renewable energy sources (RES). While most of the existing DDR schemes require iterative information exchange between the customers and the load aggregator through two-way communications, this paper studies the DDR schemes that rely on neighbor-wise communication between customers only. Such DDR schemes can be realized by low-cost wireless networks. To this end, we propose the use of a randomized alternating direction method of multipliers to develop a fully DDR algorithm. Notably, the proposed DDR algorithm is communication-efficient because it can yield promising power balance performance using a few times of neighbor-wise message exchanges. Moreover, the proposed DDR algorithm does not need synchronization between customers and is robust against random communication errors. For performing online demand response control, we combine the proposed DDR algorithm with the rolling-window-based model-predictive control method, and simple load and RES forecasting methods. By using real solar power data, we demonstrate via simulations that the proposed DDR algorithm improves the real-time power balance substantially and outperforms the existing DDR schemes that use the subgradient method for optimization.
Impact of prolonged cannabinoid excretion in chronic daily cannabis smokers' blood on per se drugged driving laws.

BACKGROUND Cannabis is the illicit drug most frequently reported with impaired driving and motor vehicle accidents. Some "per se" laws make it illegal to drive with any amount of drug in the body, while others establish blood, saliva, or urine concentrations above which it is illegal to drive. The persistence of Δ(9)-tetrahydrocannabinol (THC) in chronic daily cannabis smokers' blood is unknown. METHODS Thirty male chronic daily cannabis smokers resided on a secure research unit for up to 33 days, with daily blood collection. Samples were processed in an ice bath during sample preparation to minimize cannabinoid adsorption onto precipitant material. We quantified THC by 2-dimensional GC-MS. RESULTS Of the 30 participants, 27 were THC-positive on admission, with a median (range) concentration of 1.4 μg/L (0.3-6.3). THC decreased gradually; only 1 of 11 participants was negative at 26 days, 2 of 5 remained THC-positive (0.3 μg/L) for 30 days, and 5.0% of participants had THC ≥ 1.0 μg/L for 12 days. Median 11-hydroxy-THC concentrations were 1.1 μg/L on admission, with no results ≥ 1.0 μg/L 24 h later. 11-Nor-9-carboxy-THC (THCCOOH) detection rates were 96.7% on admission, decreasing slowly to 95.7% and 85.7% on days 8 and 22, respectively; 4 of 5 participants remained THCCOOH positive (0.6-2.7 μg/L) after 30 days, and 1 remained positive on discharge at 33 days. CONCLUSIONS Cannabinoids can be detected in blood of chronic daily cannabis smokers during a month of sustained abstinence. This is consistent with the time course of persisting neurocognitive impairment reported in recent studies.
