Practice facilitation for scale up of clinical decision support for hypertension management: study protocol for a cluster randomized control trial. Contemp Clin Trials 2023; 129:107177. [PMID: 37037392 PMCID: PMC10871131 DOI: 10.1016/j.cct.2023.107177] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Revised: 03/09/2023] [Accepted: 04/04/2023] [Indexed: 04/12/2023]
Abstract
BACKGROUND Only half of patients with hypertension have adequately controlled blood pressure. Clinical decision support (CDS) has the potential to overcome barriers to delivering guideline-recommended care and improve hypertension management. However, optimal strategies for scaling CDS have not been well established, particularly in small, independent primary care practices which often lack the resources to effectively change practice routines. Practice facilitation is an implementation strategy that has been shown to support process changes. Our objective is to evaluate whether practice facilitation provided with hypertension-focused CDS can lead to improvements in blood pressure control for patients seen in small primary care practices. METHODS/DESIGN We will conduct a cluster randomized control trial to compare the effect of hypertension-focused CDS plus practice facilitation on BP control, as compared to CDS alone. The practice facilitation intervention will include an initial training in the CDS and a review of current guidelines along with follow-up for coaching and integration support. We will randomize 46 small primary care practices in New York City who use the same electronic health record vendor to intervention or control. All patients with hypertension seen at these practices will be included in the evaluation. We will also assess implementation of CDS in all practices and practice facilitation in the intervention group. DISCUSSION The results of this study will inform optimal implementation of CDS into small primary care practices, where much of care delivery occurs in the U.S. Additionally, our assessment of barriers and facilitators to implementation will support future scaling of the intervention.

Facilitation of team-based care to improve HTN management and outcomes: a protocol for a randomized stepped wedge trial. BMC Health Serv Res 2023; 23:560. [PMID: 37259081 DOI: 10.1186/s12913-023-09533-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Accepted: 05/10/2023] [Indexed: 06/02/2023] Open
Abstract
BACKGROUND There are well-established guidelines for treating hypertension (HTN), yet only half of patients with HTN meet the defined target of < 140/90. Team-based care (TBC) is an evidence-based strategy for improving blood pressure (BP) management and control. TBC is defined as the provision of health services by at least two health professionals "who work collaboratively with patients and their caregivers to accomplish shared goals to achieve coordinated, high-quality care". However, primary care practices experience challenges to implementing TBC principles and care processes; these are more pronounced in small independent practice settings (SIPs). Practice facilitation (PF) is an implementation strategy that may overcome barriers to adopting evidence-based TBC to improve HTN management in SIPs. METHODS Using a stepped wedge randomized controlled trial design, we will test the effect of PF on the adoption of TBC to improve HTN management in small practices (< 5 FTE clinicians) in New York City, and the impact on BP control compared with usual care. We will enroll 90 SIPs and randomize them into one of three 12-month intervention waves. Practice facilitators will support SIPs to adopt TBC principles to improve implementation of five HTN management strategies (i.e., panel management, population health, measuring BP, supporting medication adherence, self-management). The primary outcome is the adoption of TBC for HTN management measured at baseline and 12 months. Secondary outcomes include the rate of BP control and sustainability of TBC and BP outcomes at 18 months. Aggregated data on BP measures are collected every 6 months in all clusters so that each cluster provides data points in both the control and intervention conditions. Using a mixed methods approach, we will also explore factors that influence the effectiveness of PF at the organization and team level. DISCUSSION This study will provide much-needed guidance on how to optimize adoption and sustainability of TBC in independent primary care settings to reduce the burden of disease related to suboptimal BP control and advance understanding of how facilitation works to improve implementation of evidence-based interventions.

Abstract
PURPOSE The purpose of this study was to explore how treatment adherence and lifestyle changes required for glycemic control in type 2 diabetes (T2D) are related to quality of life (QoL) among predominantly ethnic minority and socioeconomically disadvantaged adults engaged in making changes to improve T2D self-management. METHODS Adults with T2D in New York City were recruited for the parent study based on recent A1C (≥7.5%) and randomly assigned to 1 of 2 arms, receiving educational materials and additional self-management support calls, respectively. Substudy participants were recruited from both arms after study completion. Participants (N = 50; 62% Spanish speaking) were interviewed by phone using a semistructured guide and were asked to define QoL and share ways that T2D, treatment, self-management, and study participation influenced their QoL. Interviews were analyzed using thematic analysis. RESULTS QoL was described as a multidimensional health-related construct with detracting and enhancing factors related to T2D. Detracting factors included financial strain, symptom progression and burden, perceived necessity to change cultural and lifestyle traditions, and dietary and medical limitations. Enhancing factors included social support, diabetes education, health behavior change, sociocultural connection. CONCLUSION QoL for diverse and socioeconomically disadvantaged adults with T2D is multifaceted and includes aspects of health, independence, social support, culture, and lifestyle, which may not be captured by existing QoL measures. Findings may inform the development of a novel QoL measure for T2D.

Abstract
A 53-year-old female patient complained of 1 week of bilateral visual blurring. She was previously diagnosed with metastatic melanoma of the inguinal lymph nodes and treated with the oral targeted drug vemurafenib. She exhibited aqueous flare in the left eye, and her fundus examination revealed optic disc swelling in the left eye and bilateral serious detachment of the retinal neuroepithelial layer. Fluorescein angiography showed multiple pinpoint hyperfluorescence leakage spots in the prometaphase and appeared as multilobular dye pooling in the late phase. We diagnosed her as Vogt-Koyanagi-Harada syndrome and gave glucocorticoid treatment for eyes. Oral vemurafenib was also taken intermittently under the guidance of an oncologist. After treatment, her bilateral vision improved, the anterior segment inflammation disappeared, and the retinal neuroepithelial layer reattached, with presence of the "sunset glow" fundus.

Abstract
Objective: To investigate the dynamic characteristics of brain spontaneous activity in betel quid dependence (BQD) chewers and its relationship with clinical indexes. Method: This study was conducted in Hainan General Hospital from April to December 2019 and the data of 53 BQD chewers (37 males and 16 females, aged 20 to 58(38±11) years) and 37 healthy controls (HC) (24 males and 13 females, aged 23-57(42±12) years) were collected. All these subjects underwent resting-state functional magnetic resonance imaging (rs-fMRI) scan. The dynamic characteristics of resting fMRI indexes, including dynamic amplitude of low-frequency fluctuations (ALFF), regional homogeneity (ReHo) and degree centrality (DC) of these subjects were calculated using the sliding time window method, parameters such as age and dynamic local consistency were analyzed and compared between the two groups. Pearson correlation was used to analyze the relationship between dynamic indexes, betel quid dependence score (BQDS) and disease duration in BQD group. Results: BQD chewers showed decreased dynamic ALFF in the left orbital prefrontal cortex (0.138±0.041 vs 0.171±0.070), the right temporal pole superior temporal gyrus (0.277±0.070 vs 0.319±0.086) and the right inferior parietal lobule (0.223±0.052 vs 0.259±0.088) than HC (all P<0.05). For regional homogeneity, BQD chewers showed a decrease dynamic ReHo in the right inferior temporal gyrus (0.055±0.008 vs 0.061±0.009), the orbital prefrontal cortex (0.058±0.005 vs 0.063±0.008), the right inferior frontal gyrus (0.081±0.006 vs 0.087±0.011), the right superior occipital gyrus (0.056±0.007 vs 0.062±0.008), the left precentral gyrus (0.068±0.008 vs 0.074±0.008), and the left superior frontal gyrus (0.058±0.008 vs 0.064±0.009) than HC (all P<0.05). BQD chewers showed an increase dynamic ReHo in the right precuneus (0.095±0.009 vs 0.089±0.008) (P<0.05). There was no significant difference in DC between the two groups (all P>0.05). The relationships between three dynamic ALFF and BQDS (r=-0.104, -0.015, -0.119), seven dynamic ReHo and BQDS (r=-0.099, -0.141, -0.055, -0.078, -0.027, -0.111, -0.090), three dynamic ALFF and disease duration (r=-0.122, -0.095, -0.171), and seven dynamic ReHo and disease duration (r=0.242, -0.252, 0.035, 0.056, 0.047, 0.081, 0.169) were not statistically significant (all P>0.05). Conclusions: BQD chewers showed a decrease dynamic ReHo and/or ALFF in multiple brain regions dominated by prefrontal cortex, and an increase dynamic ReHo in the right precuneus.

Abstract
Objective: To investigate the clinical value of the bipolar tweezers-clamp for the hepatic parenchymal transection in the resection of hepatocellular carcinoma. Methods: From January 2020 to January 2021,63 patients with the hepatocellular carcinoma for hepatectomy at Department of Hepatopancreatobiliary Surgery,Yuebei People's Hospital Affiliated to Shantou University Medical College were analyzed retrospectively.According to the different instruments used in the hepatic parenchymal transection,the patients were divided into bipolar tweezers-clamp group and ultrasonic scalpel group.There were 32 patients in bipolar tweezers-clamp group,with age of (55.5±10.5)years(range:37 to 78 years),including 22 males and 10 females,tumor size was (6.0±3.4)cm(range:2.4 to 13.4 cm). There were 6 patients with portal vein tumor thrombus and 5 patients with portal hypertension. There were 31 patients in ultrasonic scalpel group,with aged(57.8±10.1)years(range:37 to 79 years),including 27males and 4 females,tumor size was(7.9±5.1)cm(range: 2.4 to 21.3 cm),3 patients with portal vein tumor thrombus and 2 patients with portal hypertension. The preoperative baseline data,operation time,blood loss,postoperative liver function and the complications were compared between two groups using t test,χ2 test and Fisher exact probabilityrespectively. Results: The operation was successfully completed in both groups.Compared with the ultrasonic scalpel group,the operation time was significantly shorter((219.3±76.4)minutes vs.(294.0±100.8)minutes,t=-3.322,P=0.002),the blood loss was less((250(475)ml vs. 500(1 050)ml,t=-2.307,P=0.026),the concentrate red blood cells transfusion volume was less(0.92(0.88)U vs. 2.32(4.00)U,Z=-1.987,P=0.047) in the bipolar tweezers-clamp group.The postoperative serum ALB level was higher in the bipolar tweezers-clamp group than that in the ultrasonic scalpel group((33.5±6.1)g/L vs. (29.5±4.2)g/L,t=3.226,P=0.020) on postoperative day 1;((35.7±4.5)g/L vs.(30.1±3.2)g/L,t=5.575,P<0.01) on postoperative day 3;((33.2±3.7)g/L vs. (31.0±4.4)g/L,t=3.020,P=0.004) on postoperative day 7. There was no significant difference in serum ALT,TBIL and PT level between the two groups(all P>0.05).No postoperative bile leakage occurred in both groups.The postoperative complications occurred in 8 cases(25.0%)in the bipolar tweezers-clamp group,including liver failure in one,and in 11 cases(35.5%)in the ultrasonic scalpel group,including liver failure in two(P>0.05). Conclusion: The bipolar tweezers-clamp is a safe and reliable method for the hepatic parenchymal transaction,which is quick and less bleeding during the hepatic resection.

Abstract
Although problems with type 2 diabetes (T2D) self-management and treatment adherence often co-occur with emotional distress, few translatable intervention approaches are available that can target these related problems in primary care practice settings. The New York City (NYC) Care Calls study is a randomized controlled trial that tests the effectiveness of structured support for diabetes self-management and distress management, delivered via telephone by health educators, in improving glycemic control, self-management and emotional well-being among predominantly ethnic minority and socioeconomically disadvantaged adults with suboptimally controlled T2D. English- and Spanish-speaking adults treated for T2D in NYC primary care practices were recruited based on having an A1C ≥ 7.5% despite being prescribed medications for diabetes. Participants (N = 812) were randomly assigned to a telephonic intervention condition with a stepped protocol of 6-12 phone calls over 1 year, delivered by a health educator, or to a comparison condition of enhanced usual care. The primary outcome is change in A1C over one year, measured at baseline and again approximately 6- and 12-months later. Secondary outcomes measured on the same schedule include blood pressure, patient-reported emotional distress, treatment adherence and self-management behaviors. A comprehensive effectiveness evaluation is guided by the RE-AIM framework (Reach, Effectiveness, Adoption, Implementation, Maintenance) to gather data that can inform dissemination and implementation of the intervention, if successful. This paper describes the study rationale, trial design, and methodology.

Abstract
Objective: To investigate the features of the full-field electroretinogram (FERG) in patients with ocular surface alkaline injury, and to clarify the clinical significance of FERG examination in alkaline ocular trauma. Methods: Retrospective series of case study. A total of 22 patients with chemical ocular surface injury who were treated in the Department of Ophthalmology of Peking University Third Hospital from May 2018 to January 2020 were selected, including 20 males (25 eyes) and 2 females (2 eyes). The age ranged from 19 to 60 years old (average, 41). There were 17 eyes with alkaline ocular trauma, 7 eyes with thermal burn, and 3 eyes with acid ocular trauma. Seventeen contralateral healthy eyes in patients with unilateral mechanical trauma were used as controls. Fourteen alkaline trauma eyes with visual acuity records were further observed according to the degree of visual impairment. All patients were subjected to different flash intensity stimuli in accordance with a standard of the International Society for Clinical Electrophysiology of Vision for dark-adapted and light-adapted full-field FERG. One-way ANOVA and SNK-q was used for the comparison between groups. The unpaired t test was used for the comparison of patients with different vision. Results: Compared with healthy eyes the injured eyes' amplitude of dark adaption FERG b-wave under the dark stimulation of 0.01 cd·s·m-2 in alkaline ocular trauma, thermal burn, acid ocular trauma was (135±85), (169±55), and (112±43) versus (341±53) μV, respectively; compared with healthy eyes, the differences were statistically significant (F=31.38; q=8.94, 5.70, 5.45;all P<0.01). Compared with healthy eyes the injured eyes' amplitude of dark adaption FERG a-wave under the dark stimulation of 3.00 cd·s·m-2 in alkaline ocular trauma, thermal burn, acid ocular trauma was (178±78), (172±35), and (99±53) versus (334±60) μV, respectively; compared with healthy eyes, the differences were statistically significant (F=24.33; q=7.04, 5.60, 5.80;all P<0.01). Compared with healthy eyes the injured eyes' amplitude of dark adaption FERG b-wave under the dark stimulation of 3.00 cd·s·m-2 in alkaline ocular trauma, thermal burn, acid ocular trauma was (354±79), (342±77), and (352±201) versus (600±78) μV, respectively; compared with healthy eyes, the differences were statistically significant (F=27.68; q=8.11, 6.51, 4.48; all P<0.01). Compared with healthy eyes the injured eyes' amplitude of dark adaption FERG OPs under the dark stimulation of 3.00 cd·s·m-2 in alkaline ocular trauma, thermal burn, acid ocular trauma was (97±54), (107±41), and (45±22) versus (206±32) μV, respectively; compared with healthy eyes, the differences were statistically significant (F=25.03; q=7.36, 5.13, 5.96; all P<0.01).There was no significant difference in FERG between patients with visual acuity≥0.2 and those with visual acuity<0.2 (P>0.05) after alkaline ocular trauma. Conclusions: By detecting the amplitude change of FERG wave form of chemical ocular trauma, in this study, the amplitude of FERG wave form in alkaline ocular trauma was generally decreased. It's suggested that alkaline ocular trauma can cause damage to the rod and cone systems of retinal. (Chin J Ophthalmol, 2020, 56: 514-518).

Abstract
OBJECTIVE Self-management education and support are essential for improved diabetes control. A 1-year randomized telephonic diabetes self-management intervention (Bronx A1C) among a predominantly Latino and African American population in New York City was found effective in improving blood glucose control. To further those findings, this current study assessed the intervention's impact in reducing health care utilization and costs over 4 years. RESEARCH DESIGN AND METHODS We measured inpatient (n = 816) health care utilization for Bronx A1C participants using an administrative data set containing all hospital discharges for New York State from 2006 to 2014. Multilevel mixed modeling was used to assess changes in health care utilization and costs between the telephonic diabetes intervention (Tele/Pr) arm and print-only (PrO) control arm. RESULTS During follow-up, excess relative reductions in all-cause hospitalizations for the Tele/Pr arm compared with PrO arm were statistically significant for odds of hospital use (odds ratio [OR] 0.89; 95% CI 0.82, 0.97; P < 0.01), number of hospital stays (rate ratio [RR] 0.90; 95% CI 0.81, 0.99; P = 0.04), and hospital costs (RR 0.90; 95% CI 0.84, 0.98; P = 0.01). Reductions in hospital use and costs were even stronger for diabetes-related hospitalizations. These outcomes were not significantly related to changes observed in hemoglobin A1c during individuals' participation in the 1-year intervention. CONCLUSIONS These results indicate that the impact of the Bronx A1C intervention was not just on short-term improvements in glycemic control but also on long-term health care utilization. This finding is important because it suggests the benefits of the intervention were long-lasting with the potential to not only reduce hospitalizations but also to lower hospital-associated costs.

Abstract
Objective: To investigate the wave variations of the electroretinography (ERG), and explore the clinical value of using ERG in alkali injury. Methods: A total of 13 patients with alkali burns who were treated in the Department of Ophthalmology of Peking University Third Hospital from May 2018 to October 2019 were selected, including 12 males and 1 female. The age ranged from 19 to 60 years old. A total of 15 injured eyes were used as the alkali burn group, meanwhile, another 15 contralateral eyes with mechanical unilateral trauma were used as the healthy controls. ERG examination was performed to compare the amplitudes of 6 activation-induced responses between the two groups. Results: Compared with control group, b-wave amplitude of dark adaption 0.01 ERG in alkali injury group decreased [(137±23) μV vs (348±14) μV, P<0.001]. Compared with control group [(335±17) μV and (368±19) μV], a-wave amplitude of dark adaption 3.0 ERG and 10.0 ERG in alkali injury groups [(172±20) μV and (220±21) μV] were decreased (both P<0.001). As for b-wave amplitude of dark adaption 3.0 ERG and 10.0 ERG, compared with control group [(610±20) μV and (612±19) μV], those of alkali injury groups [(359±21) μV and (384±21) μV] were decreased (both P<0.001). In terms of oscillatory potentials (OPs) amplitude of dark 3.0 ERG adaption, compared with control group [(209±8) μV], that of alkali injury group [(94±13) μV] was decreased (P<0.001). Compared with normal group [(58±3) μV], a-wave amplitude of light adaption 3.0 ERG in alkali injury group [(40±4) μV] was decreased (P<0.001). As for b-wave amplitude of light adaption 3.0 ERG, compared with control group [(146±6) μV], that of alkali injury group [(90±11) μV] was decreased (P<0.001). In terms of photopic 3.0 flicker 30 Hz of light adaption, compared with control group [(166±10) μV], that of alkali injury group [(93±11) μV] was decreased (P<0.001). Conclusion: Alkali injury can cause ocular surface morphological changes, meanwhile, it leads to the alternations of the visual function.

Abstract
Supportive housing addresses a fundamental survival need among homeless persons, which can lead to reduced risk of diabetes mellitus and improved diabetes care. We tested the association between supportive housing and diabetes outcomes among homeless adults who were eligible for New York City's supportive housing program in 2007-2012. We used multiple administrative data sources, identifying 7,525 Medicaid-eligible adults. The outcomes included receiving medical evaluation and management services, hemoglobin A1C and lipid testing (n = 1,489 persons with baseline diabetes), and incidence of new diabetes diagnoses (n = 6,036 persons without baseline diabetes) in the 2 years postbaseline. Differences in these outcomes by placement were estimated using inverse-probability-of-treatment weighting. Placed persons were more likely to receive evaluation and management services (relative risk (RR) = 1.03, 95% confidence interval (CI): 1.01, 1.04) than unplaced persons. For those with baseline diabetes, placed persons were more likely to receive hemoglobin A1C tests (RR = 1.10, 95% CI: 1.02, 1.19) and lipid tests (RR = 1.09, 95% CI: 1.02, 1.17). For those without baseline diabetes, placement was also associated with lower risk of new diabetes diagnoses (RR = 0.87, 95% CI: 0.76, 0.99). These findings show that benefits of supportive housing may be extended to diabetes care and prevention.

Abstract
OBJECTIVES Cardiovascular disease (CVD) is the leading cause of mortality in the United States. The risk for developing CVD is usually calculated and communicated to patients as a percentage. The calculation of heart age-defined as the predicted age of a person's vascular system based on the person's CVD risk factor profile-is an alternative method for expressing CVD risk. We estimated heart age among adults aged 30-74 in New York City and examined disparities in excess heart age by race/ethnicity and sex. METHODS We applied data from the 2011, 2013, and 2015 New York State Behavioral Risk Factor Surveillance System to the non-laboratory-based Framingham risk score functions to calculate 10-year CVD risk and heart age by sex, race/ethnicity, and selected sociodemographic groups and risk factors. RESULTS Of 6117 men and women in the study sample, the average heart age was 5.7 years higher than the chronological age, and 2631 (43%) adults had a predicted heart age ≥5 years older than their chronological age. Mean excess heart age increased with age (from 0.7 year among adults aged 30-39 to 11.2 years among adults aged 60-74) and body mass index (from 1.1 year among adults with normal weight to 11.8 years among adults with obesity). Non-Latino white women had the lowest mean excess heart age (2.3 years), and non-Latino black men and women had the highest excess heart age (8.4 years). CONCLUSIONS Racial/ethnic and sex disparities in CVD risk persist among adults in New York City. Use of heart age at the population level can support public awareness and inform targeted programs and interventions for population subgroups most at risk for CVD.

Abstract
Objective: To investigate the molecular mechanism of poor response of nucleoside and interferon therapy in some patients with chronic hepatitis B (CHB) and the negative regulatory factor of suppressor of cytokine signaling 3 (SOCS3) expression in the interferon-signaling pathway. Also, study the clinical relationship between SOCS3 and antiviral efficacy of nucleoside and interferon. Methods: Peripheral blood and matched liver tissue samples from 54 CHB patients who participated in the OSST study were selected. HBsAg was measured at different time points (baseline and weeks 12, 24, 36, and 48) to observe the antiviral efficacy. Meanwhile, quantitative real-time PCR, and immunohistochemistry were used to detect the expression levels of SOCS3 mRNA in peripheral blood mononuclear cells (PBMCs) and matched liver tissues (baseline and 48 weeks). At the end of the 48-week treatment, patients with HBsAg negative or HBeAg seroconversion were defined as response group, and vice versa. Paired t-tests were used to compare normal distribution variables and the Mann-Whitney U test was used to compare the median differences between groups of non-normally distributed variables. Results: After 48 weeks of treatment, serum HBsAg levels in the Peg-IFN group continued to decline (average decrease of 1.14 log(10) IU / ml at week 48; P = 0.001 compared with baseline), while the entecavir group remained almost unchanged during treatment (average decrease was 0.05 log(10) IU / ml at week 48; compared with baseline P = 0.12). The expression of SOCS3 mRNA (Messenger RNA, mRNA) in peripheral blood and liver tissues of non-responder group was significantly higher than the response group in the course of Peg-IFNα2a treatment. The immunohistochemical results of liver tissue showed that the expression of SOCS3 in the non-responder group was significantly higher than that in the response group at baseline (P = 0.027). After 48 weeks of treatment with Peg-IFNα2a, the expression of SOCS3 in the non-responder group was significantly higher than that in the baseline and response groups (P = 0.003, P = 0.012, respectively). Conclusion: The expression of SOCS3 in peripheral blood mononuclear cells and liver tissues of non-responding CHB patients was significantly higher than that of responding CHB patients during interferon and nucleoside antiviral therapy. We speculated that SOCS3 might affect the antiviral efficacy through negative regulation of JAK-STAT signaling pathway, and partly expose the mechanism of interferon resistance.

Abstract
Federal value-based payment programs require primary care practices to conduct quality improvement activities, informed by the electronic reports on clinical quality measures that their electronic health records (EHRs) generate. To determine whether EHRs produce reports adequate to the task, we examined survey responses from 1,492 practices across twelve states, supplemented with qualitative data. Meaningful-use participation, which requires the use of a federally certified EHR, was associated with the ability to generate reports-but the reports did not necessarily support quality improvement initiatives. Practices reported numerous challenges in generating adequate reports, such as difficulty manipulating and aligning measurement time frames with quality improvement needs, lack of functionality for generating reports on electronic clinical quality measures at different levels, discordance between clinical guidelines and measures available in reports, questionable data quality, and vendors that were unreceptive to changing EHR configuration beyond federal requirements. The current state of EHR measurement functionality may be insufficient to support federal initiatives that tie payment to clinical quality measures.

Abstract
OBJECTIVE Focusing health interventions in places with suboptimal glycemic control can help direct resources to neighborhoods with poor diabetes-related outcomes, but finding these areas can be difficult. Our objective was to use indirect measures versus a gold standard, population-based A1C registry to identify areas of poor glycemic control. RESEARCH DESIGN AND METHODS Census tracts in New York City (NYC) were characterized by race, ethnicity, income, poverty, education, diabetes-related emergency visits, inpatient hospitalizations, and proportion of adults with diabetes having poor glycemic control, based on A1C >9.0% (75 mmol/mol). Hot spot analyses were then performed, using the Getis-Ord Gi* statistic for all measures. We then calculated the sensitivity, specificity, positive and negative predictive values, and accuracy of using the indirect measures to identify hot spots of poor glycemic control found using the NYC A1C Registry data. RESULTS Using A1C Registry data, we identified hot spots in 42.8% of 2,085 NYC census tracts analyzed. Hot spots of diabetes-specific inpatient hospitalizations, diabetes-specific emergency visits, and age-adjusted diabetes prevalence estimated from emergency department data, respectively, had 88.9%, 89.6%, and 89.5% accuracy for identifying the same hot spots of poor glycemic control found using A1C Registry data. No other indirect measure tested had accuracy >80% except for the proportion of minority residents, which had 86.2% accuracy. CONCLUSIONS Compared with demographic and socioeconomic factors, health care utilization measures more accurately identified hot spots of poor glycemic control. In places without a population-based A1C registry, mapping diabetes-specific health care utilization may provide actionable evidence for targeting health interventions in areas with the highest burden of uncontrolled diabetes.

Multistage Coupling of Laser-Wakefield Accelerators with Curved Plasma Channels. PHYSICAL REVIEW LETTERS 2018; 120:154801.

Abstract
Multistage coupling of laser-wakefield accelerators is essential to overcome laser energy depletion for high-energy applications such as TeV-level electron-positron colliders. Current staging schemes feed subsequent laser pulses into stages using plasma mirrors while controlling electron beam focusing with plasma lenses. Here a more compact and efficient scheme is proposed to realize the simultaneous coupling of the electron beam and the laser pulse into a second stage. A partly curved channel, integrating a straight acceleration stage with a curved transition segment, is used to guide a fresh laser pulse into a subsequent straight channel, while the electrons continue straight. This scheme benefits from a shorter coupling distance and continuous guiding of the electrons in plasma while suppressing transverse beam dispersion. Particle-in-cell simulations demonstrate that the electron beam from a previous stage can be efficiently injected into a subsequent stage for further acceleration while maintaining high capture efficiency, stability, and beam quality.

Abstract
In the present study, we examined the longitudinal associations between residential environmental factors and glycemic control in 182,756 adults with diabetes in New York City from 2007 to 2013. Glycemic control was defined as a hemoglobin A1c (HbA1c) level less than 7%. We constructed residential-level measures and performed principle component analysis to formulate a residential composite score. On the basis of this score, we divided residential areas into quintiles, with the lowest and highest quintiles reflecting the least and most advantaged residential environments, respectively. Several residential-level environmental characteristics, including more advantaged socioeconomic conditions, greater ratio of healthy food outlets to unhealthy food outlets, and residential walkability were associated with increased glycemic control. Individuals who lived continuously in the most advantaged residential areas took less time to achieve glycemic control compared with the individuals who lived continuously in the least advantaged residential areas (9.9 vs. 11.5 months). Moving from less advantaged residential areas to more advantaged residential areas was related to improved diabetes control (decrease in HbA1c = 0.40%, 95% confidence interval: 0.22, 0.55), whereas moving from more advantaged residential areas to less advantaged residential areas was related to worsening diabetes control (increase in HbA1c = 0.33%, 95% confidence interval: 0.24, 0.44). These results show that residential areas with greater resources to support healthy food and residential walkability are associated with improved glycemic control in persons with diabetes.

Abstract
OBJECTIVE To evaluate the bonding ability of one representative self-etch adhesive system by applying the micro-shear bond strength test method with different concentrations of carbodiimide [1-ethyl-3-(3-dimethylaminopropyl) carbodiimide, EDC] ethanol solution pretreatment. METHODS Extracted sound human third molars were collected from patients ranging 18 to 40 years. In the study, 80 molars were first sectioned to prepare a flat middle coronal dentin surface and then were randomly divided into 5 groups (n=16) according to without/with different surface treatments [blank control; 80% (volume fraction) ethanol control; EDC ethanol solution of three concentrations (0.01 mol/L, 0.3 mol/L and 0.5 mol/L)]. Each specimen underwent a micro-shear bond strength test and failure mode observation. The data collected were subjected to statistical analysis using one-way ANOVA and post hoc Tukey's test to analyze the difference of the micro-shear bond strength, and chi-square test/Fisher's exact test for the failure mode frequency of the micro-shear bond strength test specimens at a significance level of P=0.05. RESULTS The micro-shear bond strength of the three concentration EDC treatments were (35.29±8.97) MPa (0.01 mol/L EDC treatment group), (40.24±9.68) MPa (0.3 mol/L EDC treatment group), (37.38±9.66) MPa (0.5 mol/L EDC treatment group) separately; and that of the 80% ethanol group was (37.49±7.76) MPa. All micro-shear bond strength value of the above four groups was statistically higher than that of the blank control group [(33.81±7.98) MPa]. The immediate micro-shear bond strength and failure mode was of no statistically significant difference among all the groups. It was noticed that the immediate micro-shear bond strength of 0.3 mol/L was higher than that of all the other groups, especially higher than that of the 80% ethanol pretreatment group despite that there was no significant difference among all the groups. And the test of failure mode indicated that the cohesive failure was more common, while the frequency of adhesive failure was rare in each experimental group. CONCLUSION EDC pretreatment had no adverse effect on the immediate micro-shear bond strengths of Clearfil SE Bond. Meanwhile, EDC treatment did not cause more adhesive failure in immediate micro-shear test, which had further denoted what was said above. However, it needs more research to illustrate the anti-enzymatic role of EDC in dentin bonding.

Abstract
We present a case of phytodermatitis caused by a poisonous plant known as poison ivy. It is one of the leading causes of allergic contact dermatitis and it causes significant morbidity in the United States. Prevention of the disease is by identification and avoidance of the plant. Barrier protection minimises the chance of contact and prompt rinsing with soap water limits antigen exposure after skin contact. General approach to treatment of allergic contact dermatitis can be applied but special precaution should be taken on the duration of systemic steroid therapy. Too short a course of oral steroid may result in a more severe recurrent flare. High potency topical steroids may limit the development of skin lesions. (Hong Kong j.emerg.med. 2011; 18:335-338)

Abstract
BACKGROUND Gastrointestinal (gi) symptoms are the most notable side effects of chemotherapeutic drugs; such symptoms are currently treated with drugs. In the present study, we investigated the effect of acupuncture on gi symptoms induced by chemotherapy in patients with advanced gastric cancer. METHODS A cohort of 56 patients was randomly divided into an experimental group and a control group. All patients received combination chemotherapy with oxaliplatin-paclitaxel. Patients in the experimental group received 30 minutes of acupuncture therapy daily for 2 weeks. The frequency and duration of nausea, vomiting, abdominal pain, and diarrhea, the average days and costs of hospitalization, and quality-of-life scores were compared between the groups. RESULTS Nausea was sustained for 32 ± 5 minutes and 11 ± 3 minutes daily in the control and experimental groups respectively (p < 0.05). On average, vomiting occurred 2 ± 1 times daily in the experimental group and 4 ± 1 times daily in the control group (p < 0.05). Abdominal pain persisted for 7 ± 2 minutes and 16 ± 5 minutes daily in the experimental and control groups respectively (p < 0.05). On average, diarrhea occurred 1 ± 1 times daily in the experimental group and 3 ± 1 times daily in the control group (p < 0.05). The average quality-of-life score was higher in the experimental group than in the control group (p < 0.05). No adverse events were observed for the patients receiving acupuncture. CONCLUSIONS Acupuncture, a safe technique, could significantly reduce gi symptoms induced by chemotherapy and enhance quality of life in patients with advanced gastric cancer.

Abstract
The impact of asthma, exposure period, and filter condition downstream of the mixing box of air-conditioning system on building occupants' perceptual response, work performance, and salivary α-amylase secretion during exposures to ozone and its initiated chemistry products is studied. The experiments were conducted in a field environmental chamber (FEC) (240 m(3)) simulating an office environment. Experiments were conducted during periods when the air-handling system operated with new or used pleated panel filters at constant recirculation (7/h) and ventilation (1/h) rates. Average ozone and secondary organic aerosols (ozone-initiated chemistry products) measured during non-asthmatic and asthmatic subjects' 3-h exposures in the FEC were in the ranges approximately 20-37 ppb and approximately 1.6-3 μg/m(3), respectively. Asthmatic subjects' perceived odor intensity and sensory (eye, nose, and throat) irritation ratings were generally lower than those of non-asthmatic subjects, possibly explaining why asthmatic subjects accept perceived air quality more than non-asthmatic subjects. However, asthmatic subjects' perceived physiological-like symptom ratings (flu, chest tightness, and headache) and concentrations of secreted salivary α-amylase were generally higher than those of non-asthmatic subjects. Asthmatic subjects had significantly lower accuracy than non-asthmatic subjects in a task that required higher concentration although they had higher work speed. Filter condition did not make any significant difference for subjects' responses.

Abstract
Electronic health records (EHRs) have great potential to serve as a catalyst for more effective coordination between public health departments and primary care providers (PCP) in maintaining healthy communities. As a system for documenting patient health data, EHRs can be harnessed to improve public health surveillance for communicable and chronic illnesses. EHRs facilitate clinical alerts informed by public health goals that guide primary care physicians in real time in their diagnosis and treatment of patients. As health departments reassess their public health agendas, the use of EHRs to facilitate this agenda in primary care settings should be considered. PCPs and EHR vendors, in turn, will need to configure their EHR systems and practice workflows to align with public health priorities as these agendas include increased involvement of primary care providers in addressing public health concerns.

Abstract
We assessed patient experiences before and one year after electronic health record (EHR) implementation among primary care practices in New York City. These practices represented an ethnically diverse population in lower-income, urban communities. Surveys, available in English, Spanish, and Chinese languages, were administered at 10 sites. Generally, patients reported positive responses during both periods. After EHR implementation, patients were more likely to want e-mail communication with their doctors' office. The 70% of patients with Internet access were generally more satisfied with their experience and more likely to recognize benefits of EHRs. However, older patients and those with lower education levels or chronic diseases were significantly less likely than their counterparts to use the Internet. Therefore, disparities in Internet access could potentially lead to unequal access and use of healthcare if not addressed. Practices should routinely record patient communication preferences within the EHR, to tailor communications and improve patient experiences.

We compared emergency department and ambulatory care syndromic surveillance systems during the pandemic (H1N1) 2009 outbreak in New York City. Emergency departments likely experienced increases in influenza-like-illness significantly earlier than ambulatory care facilities because more patients sought care at emergency departments, differences in case definitions existed, or a combination thereof.

Abstract
The objective of this study was to determine the feasibility of a novel syringe-needle guidance technique (SNG), and its impact on the perioperative variables and outcomes of patients undergoing an outside-in transobturator tape procedure (TOT). Between November 2006 and May 2008, 48 consecutive women who underwent TOT with SNG were included. Another 25 women without SNG between March 2004 and October 2006 were included as a historical control. There were no significant differences in hospital stays and complication rates between the two groups. However, the operating time was shorter (mean 23.0 vs 28.3 min, p=0.008) in the SNG group than in the control group. The presence of the SNG technique was the sole predictor of the operating time (p=0.003). In conclusion, the SNG technique is a feasible method to provide help in inserting the tunneller of TOT through the transobturator foramen, and did not compromise the outcome.

A 68-year-old Chinese woman presented with generalized reticulated dark-brown hyperpigmentation on the trunk, face and limbs, oral Wickham's striae, sparse scalp hair and dark-red reticulated streaks on the occiput of the head and on the neck, some dark-red to violaceous papules on the face, scalp and flanks, light-yellow, deep-seated papules on the palms and soles, and small porcelain-white papules on the dorsal and lateral fingers. The histological features were consistent with the diagnosis of lichen planus (LP). To our knowledge, LP-induced generalized reticulated hyperpigmentation is very rare and this is the first report of the clinical features on the fingers, palms and soles.

Abstract
BACKGROUND Medication reconciliation (MedRecon) has been a Joint Commission National Patient Safety Goal since 2006. However, there is scant literature on the evaluation of electronic MedRecon systems in reducing medication errors and on improving reliability of the MedRecon process. METHODS An electronic MedRecon system was designed and implemented in an acute inpatient care facility. Two analyses were performed: (1) one based on a 2-week pilot evaluation of the system based on 120 MedRecon events, and (2) a more comprehensive 17-month evaluation of the system, based on 19,356 MedRecon events. RESULTS The unintended discrepancy rate between a patient's home medications and admission medication orders was reduced from 20% during the pilot phase to 1.4%. The omission of a home medication was the most common type of discrepancy. Nighttime admission (8 P.M.-8 A.M.), total home medications > four, patient age > 65 years, and resident physician performing the medication reconciliation were found to have a significant positive correlation (p < .05) with the discrepancy rate. Using computerized alerts improved compliance with the MedRecon process from 34% to 98%-100%. DISCUSSION Using a multidisciplinary process based on an electronic system substantially reduced medication errors on admission, suggesting that an electronic MedRecon system can be an important tool in improving patient safety. The use of an interactive reminder alert in the MedRecon system improved systems reliability by ensuring physician compliance with MedRecon performance. Although computerized physician order entry (CPOE) decision support tools are an important component of medication error prevention strategies, they alone are not sufficient to prevent errors of prescribing.

Abstract
In Taiwan, the age-specific fertility rate for adolescent girls aged 15-19 years has remained at 14-18/1,000 births during the past two decades, which is the highest among developed countries in Asia. There was a surprisingly high age-specific fertility rate for married women aged 15-19 years at 726 per 1,000 in 1994, much higher than that of the United States. Adolescent childbearing causes many adverse outcomes including unwanted and unstable marriage, repeated childbearing during adolescence, and increased risks of having low birth weight and preterm births and neonatal mortality. Studies in Taiwan showed that adolescent childbearing is associated with their poor knowledge but open attitude and behaviour on sexuality, the inadequate contraceptive services for the adolescents in need, some risk-taking behaviors, family dysfunction and low socioeconomic status of the adolescents' families. About two-thirds of the fathers of infants born to adolescent girls were adults, even old adults with a low education level Effective strategies for adolescent childbearing prevention range from sex education, the direct provision of contraceptive supplies, and to life options programmes, especially for the adolescents with high risk of adolescent pregnancy. Reducing the incidence of adolescent childbearing by active use of contraception is more important and practical than prohibiting adolescent sexual activity.

The purpose of this study was to determine whether provider participation in New York State QIO activities resulted in significant improvements in the quality of diabetes care during the recent contract cycle with the Centers for Medicare & Medicaid Services. RESEARCH DESIGN A retrospective analysis between participating and nonparticipating providers on their performance in 3 quality measures (biennial ophthalmology examination, biennial lipid profile monitoring, annual hemoglobin A1c monitoring) was used. Data of New York State Medicare beneficiaries before and after QIO intervention activities were examined to determine change in performance. General linear models were created to examine the effect QIO participation had on the change in performance for each measure. RESULTS Providers who participated in QIO activities had significant absolute improvements in lipid monitoring compared with nonparticipating providers at high baseline performance for low (3.10%, P < 0.001), medium (2.57%, P < 0.001), and high (1.51%, P = 0.002) baseline patient volume, and medium baseline performance for low (2.38%, P < 0.001), and medium (1.85%, P < 0.001) baseline patient volume. The same trend was seen for hemoglobin A1c monitoring (4.28%, P < 0.001; 3.57%, P < 0.001; 2.15%, P < 0.001; 2.63%, P = 0.001; 1.92%, P = 0.006). For ophthalmology examination, participation resulted in significant changes at low (2.28%, P = 0.003) and medium (1.73%, P = 0.009) baseline patient volume. CONCLUSION The study results suggest QIO activities can improve outpatient diabetes care; however, limitations in the study design preclude any definitive remarks.

Abstract
The objective of this study was to investigate the association between chromium (Cr) concentrations and sister chromatid exchanges (SCE) formation in Cr workers and to assess the effects of susceptible genes (glutathione S-transferase M1 and T1) on the frequency of deletion and SCE/cell. Urinary Cr concentration was significantly elevated in Cr workers (3.67 +/- 3.89 microg/g creatinine) compared to control group (1.21 +/- 1.16 microg/g creatinine, P < 0.01). There was also a significant difference of superoxide dismutase (SOD) levels between Cr workers (6.86 +/- 0.80 U/mg Hb) and controls (7.16 +/- 0.53 U/mg Hb, P < 0.01). The frequencies of SCE and high frequency cells (HFC) were significantly correlated with smoking habits and with duration of exposure to Cr. A significantly higher percentage (50%) of Cr workers had both the null GSTM1 and GSTT1 genotype as compared to 10% of the controls (P < 0.01). However, the chromosomal DNA damage effect of GSTM1 and GSTT1 genotypes, individually or in combination, was not revealed in Cr exposed workers.

Abstract
Isoliquiritigenin, which is possibly a principal anti-tumor constituent of licorice, a traditional Chinese herb, was examined for apoptosis-inducing activity in human gastric cancer MGC-803 cells. Typical morphological and biochemical features of apoptosis including cell shrinkage, chromatin condensation, DNA ladder formation, and appearance of apoptotic peaks (subG(1)) were observed in MGC-803 cells with isoliquiritigenin treatment. Using Fluo-3 and Rh123 as fluorescent probes, respectively, it was found that the intracellular free calcium concentration increased and the mitochondrial transmembrane potential (Deltapsi(m)) decreased in a dose-dependent manner in apoptotic cells. These results suggest that isoliquiritigenin induced apoptosis of MGC-803 cells through calcium- and Deltapsi(m)-dependent pathways, indicating that it is potentially useful as a natural anti-cancer agent.

Large drug resistance virulence plasmids of clinical isolates of Salmonella enterica serovar Choleraesuis. Antimicrob Agents Chemother 2001; 45:2299-303.

Abstract
Salmonella enterica serovar Choleraesuis generally causes systemic human salmonellosis without diarrhea, and therefore, antimicrobial treatment is essential for such patients. The drug resistance information on this organism is thus of high value. Serovar Choleraesuis usually harbors a virulence plasmid (pSCV) of 50 kb in size. Of the 16 clinical isolates identified to be serovar Choleraesuis, all except one harbored a pSCV and seven of them carried a pSCV of more than 125 kb in size. A pSCV was defined as a plasmid carrying spvC and characteristic deletions detected by PCR and by DNA-DNA hybridization (for the former criterion). The results of PCR, restriction fragment profiles, and Southern DNA-DNA hybridizations of the profiles all indicated that such larger pSCVs were derived from the 50-kb plasmid recombined with non-pSCVs found in some clinical isolates. Fifteen of the 17 strains, including a laboratory strain, were then tested for drug resistance against 16 antibiotics with E-test and the dilution method. The laboratory strain, which harbored a 50-kb pSCV and a 6-kb non-pSCV, was resistant only to sulfonamides (SUL), and its resistance gene, sulII, checked with PCR and DNA-DNA hybridization, was located on the 6-kb non-pSCV. All 14 clinical strains were resistant to multiple drugs. Of the 14, 7 were resistant to SUL, and the resistance gene was located on a plasmid. The sulII gene, but not bla(TEM-1), was carried only on the 6-kb non-pSCV. Of the remaining six large plasmids, three of 90 kb, two of 136 kb, and one of 140 kb, the last three were pSCVs and carried the other SUL gene (sulI) and the bla(TEM-1) gene. The six strains were also resistant to trimethoprim-sulfamethoxazole. None of the 50-kb pSCVs carried resistance genes. These drug resistance genes on the large pSCVs were apparently also acquired through recombination.

Abstract
Tissue remodeling is a complex process that can occur in response to a wound or injury. In lung tissue, abnormal remodeling can lead to permanent structural changes that are characteristic of important lung diseases such as interstitial pulmonary fibrosis and bronchial asthma. Fibroblast-mediated contraction of three-dimensional collagen gels is considered an in vitro model of tissue contraction and remodeling, and the epithelium is one factor thought to modulate this process. We studied the effects of epithelium on collagen density and contraction using two-photon laser scanning microscopy (TPLSM). TPLSM was used to image autofluorescence of collagen fibers in an engineered tissue model of the human respiratory mucosa -- a three-dimensional co-culture of human lung fibroblasts (CCD-18 lu), denatured type I collagen, and a monolayer of human alveolar epithelial cell line (A549) or human bronchial epithelial cell line (16HBE14o(-)). Tissues were imaged at days 1, 8, and 15 at 10 depths within the tissue. Gel contraction was measured concurrently with TPLSM imaging. Image analysis shows that gels without an epithelium had the fastest rate of decay of fluorescent signal, corresponding to highest collagen density. Results of the gel contraction assay show that gels without an epithelium also had the highest degree of contraction (19.8% +/- 4.0%). We conclude that epithelial cells modulate collagen density and contraction of engineered human lung tissue, and TPLSM is an effective tool to investigate this phenomenon.

Abstract
OBJECTIVE To evaluate the effectiveness, toxicity and prospective application of hepatic arterial infusion (HAI) with Embolized Curcuma Aromatic oil (CAO) in treating primary liver cancer (PLC). METHODS In the treated group, 32 patients with PLC were treated by HAI with 1-3 ml of embolized CAO and oral administration of Chinese herbal medicine. In the control group, 32 patients with PLC were treated with transcatheter artery chemoembolization (TACE). RESULTS In the treated group, one patient attained complete remission (CR) and 13 partial remission (PR), the total effective rate being 43.75%. The level of alpha fetal protein (AFP) turned to normal range in 7 cases and decreased in other 7. In the control group, 10 obtained PR and the total effective rate being 31.25%, AFP level turned to normal in 5 and decreased in 2. There was no statistical significance between the two groups. The incidences of post-embolism syndrome, such as fever, abdominal pain and vomiting were similar between the two groups but no myelosuppression occurred in the treated group with significant difference (P < 0.01) as comparing with that in the control group. The mean survival time, median survival time, 1-, 2- and 3-year survival rate in the treated group was 11.5 months, 10 months, 37.5%, 13.3% and 6.9% respectively, while in the control group was 7.25 months, 6 months, 15.6%, 3.2% and 0 respectively. The treated group was better in mean survival time, median survival time and 1-year survival rate than that of the control group (P < 0.05). CONCLUSION HAI with embolized CAO showed a similar favorite effect in treating PLC as that of TACE, but superior than TACE with longer survival time and milder myelosuppression.

Abstract
The frequency of sister chromatid exchanges (SCEs), high SCE frequency cells (HFCs), and genetic polymorphism of genotypes glutathione S-transferase (GST) M1 and T1 were analyzed in peripheral lymphocytes of 35 workers occupationally exposed to chromium (Cr) and 35 matched control group. Results showed that workers exposed to Cr showed 6.07 SCE/cell, as compared to 4.76 SCE/cell for the control group (p<0.01). Smokers showed a statistically significant higher frequency of SCE than non-smokers in both groups. The work duration of Cr workers was an important factor. Workers exposed for more than 5 years showed a significantly higher level of SCEs (p<0.05). Workers exposed to Cr for 5 or more years had higher HFC rates (51.4%) than those exposed for less than 5 years (22.9%), with an odds ratio of 4.5 times than those exposed for less than 5 years. In HFC analysis, Cr workers who smoked showed a higher level of HFC (60%) than the control group (5.7%) and also had a higher odds ratio (60.4) compared with the control group. Among non-smokers, the odds ratio was 9.0. Another objective of this study is to investigate the relationship between SCE and genetic polymorphisms of GST M1 and T1 in Cr workers. The results showed that the incidence of GSTM1 null genotype was 60% in the control group and 77.1% in Cr workers, and percentages of GSTT1 deletion were 42.9% and 62.9% in control and exposed individuals, respectively. There was a slightly increased frequency of SCE among Cr workers with GSTM1 null genotype as opposed to non-null genotype individuals. A similar result was seen among the control group; however, there were no statistically significant differences. In conclusion, the current study found the positive induction of SCE in workers who smoked or/and were exposed to Cr. However, different GST genotypes did not influence the level of cytogenetic damage between groups. Despite slight variation in numbers, they all appear to be not different.

Abstract
A two-stage string matching method for the recognition of two-dimensional (2-D) objects is proposed in this work. The first stage is a global cyclic string matching. The second stage is a local matching with local dissimilarity measure computing. The dissimilarity measure function of the input shape and the reference shape are obtained by combining the global matching cost and the local dissimilarity measure. The proposed method has the advantage that there is no need to set any parameter in the recognition process. Experimental results indicate that the hostage string matching approach significantly improves the recognition rates compared to the one-stage string matching method.

Abstract
Coping strategies were compared among family caregivers of Alzheimer's disease patients in Shanghai, China (n = 110) and San Diego, California (n = 139). Four coping factors were reliably consistent in both samples, supporting their widespread relevance to life adversity; behavioral confronting, behavioral distancing/social support, cognitive confronting, and cognitive distancing. Shanghai and San Diego caregivers endorsed similar rates of coping, but Shanghai caregivers reported fewer symptoms of depression and anxiety. Although coping strategies were similar, cultural ideals promoting family interdependence, veneration of elderly family members, and acceptance of traditional family roles may have reduced the psychological impacts of caregiving in the Shanghai sample.

Abstract
The development of sialidase inhibitor-based potential anti-influenza drugs using rational drug design techniques has been of recent interest. The present study details as investigation of the active site of influenza virus sialidase by using the program GRID in an attempt to design more potent inhibitors in the hope they will eventually lead to anti-influenza drugs. A number of different probes (amino, carboxy, hydroxy, methyl, etc) have been used in an effort to determine the functional groups most likely to improve the binding of the starting template 2-deoxy-2,3-didehydro-N-acetylneuraminic acid (Neu5Ac2en). The data have correctly predicted the binding regions for the carboxylate, acetamido (NH and methyl), and glycerol (OH) groups of N-acetylneuraminic acid. Moreover, the data suggest that the addition of certain functionalities (amino group) at the C-4 position should enhance the overall binding.

Abstract
Nine isolates of avian reovirus (ARV) from both healthy birds and birds with different clinical illness and one commercially available vaccine strain were selected and characterized by analysis of the migration pattern of their genomic double-stranded RNA (dsRNA) segments following separation by polyacrylamide gel electrophoresis. Different electropherotypes were observed and analyzed. The results show that the dsRNA segments of ARV were markedly polymorphic among isolates within the same serotype as well as among different serotypes. The results also show no correlation between electropherotype and disease state.

Abstract
The Chinese Neurology and Psychiatry Association conducted a national field trial of its Chinese Classification and Diagnostic Criteria of Mental Disorders (CCMD-2) involving 26 provinces and municipalities, 80 psychiatric institutes, and 224 professionals. The results were as follows: (1) 95.2% of researchers considered the comprehensibility of the CCMD-2 diagnostic criteria good. Within the ten major categories, comprehensibility ranged from 85.7% to 100%. (2) Of those surveyed concerning the acceptability of the CCMD-2 diagnostic criteria, 85.9% considered them acceptable. In individual classifications, the rate ranged from 74.1% to 95.2%. (3) 1498 cases were tested. The overall applicability rate which indicated the consistency between the CCMD-2 result and the actual clinical diagnoses was found to be 87.6%, (averaging Kappa = 0.82, P < 0.01), better than those obtained from non-Chinese systems of diagnosis.

Abstract
Two potent inhibitors based on the crystal structure of influenza virus sialidase have been designed. These compounds are effective inhibitors not only of the enzyme, but also of the virus in cell culture and in animal models. The results provide an example of the power of rational, computer-assisted drug design, as well as indicating significant progress in the development of a new therapeutic or prophylactic treatment for influenza infection.
