An Analysis of Pathway Programs and Social Integration in the Retention of International Chinese College Students: A Case Study Approach
2017
As of 2016 the number of international students in the United States has reached over one million. Institutions of higher education in the United States have been attracting increasing numbers of international college students, primarily from China and other Southeast Asian countries. As a result, organizations such as the Institute of International Education have encouraged colleges and universities to create pathway programs. Pathway programs accept international students who do not have strong English language and/or academic skills, yet have a desire to study abroad. These students take English as a Second Language (ESL) courses at the university before beginning their degree courses. Some program models also have students taking their first-year courses apart from the rest of the student body to help these students close their skill gaps. However, this study focused solely on a pathway program that offers only ESL courses. Previous studies have shown that students who have academic language proficiency, yet lack the ability to integrate socially, often struggle with acculturation. This, in turn, can lead to problems with persistence in their course work and ultimately lack of degree completion. The purpose of this study was to evaluate the social integration of international Chinese students comparing those who participated in the ESL program and those that did not at the subject university. The study examined the influence of this treatment on college retention and on self-reported social integration of international Chinese students. The study findings demonstrate that international Chinese students at this subject university who have received the intervention persist, having similar graduation rates compared to the general cohort, similar retention rates to the general cohort; and equal to or declining grade point averages based on the treatment-level. The study also shows that the ESL students have less acculturative stress and are more socially active in their college community than the non-ESL students. The effects of this social intervention have been positive not only at the start of their degree programs, but carry through their program. The study presents evidence as to the benefits the treatment offers towards persistence at this university, which supports pathway programs.

Psychological advocacy towards healing (PATH): A randomized controlled trial of a psychological intervention in a domestic violence service setting
2018
Experience of domestic violence and abuse (DVA) is associated with mental illness. Advocacy has little effect on mental health outcomes of female DVA survivors and there is uncertainty about the effectiveness of psychological interventions for this population.
To test effectiveness of a psychological intervention delivered by advocates to DVA survivors.
Pragmatic parallel group individually randomized controlled trial of normal DVA advocacy vs. advocacy + psychological intervention. Statistician and researchers blinded to group assignment. Setting: specialist DVA agencies; two UK cities. Participants: Women aged 16 years and older accessing DVA services.
Eight specialist psychological advocacy (SPA) sessions with two follow up sessions.
Primary outcomes at 12 months: depression symptoms (PHQ-9) and psychological distress (CORE-OM). Primary analysis: intention to treat linear (logistic) regression model for continuous (binary) outcomes.
263 women recruited (78 in shelter/refuge, 185 in community), 2 withdrew (1 community, control group; 1 intervention, refuge group), 1 was excluded from the study for protocol violation (community, control group), 130 in intervention and 130 in control groups. Recruitment ended June 2013. 12-month follow up: 64%. At 12-month follow up greater improvement in mental health of women in the intervention group. Difference in average CORE-OM score between intervention and control groups: -3.3 points (95% CI -5.5 to -1.2). Difference in average PHQ-9 score between intervention and control group: -2.2 (95% CI -4.1 to -0.3). At 12 months, 35% of the intervention group and 55% of the control group were above the CORE-OM -2clinical threshold (OR 0.32, 95% CI 0.16 to 0.64); 29% of the intervention group and 46% of the control group were above the PHQ-9 clinical threshold (OR 0.41, 95% CI 0.21 to 0.81).
64% retention at 12 months.
An eight-session psychological intervention delivered by DVA advocates produced clinically relevant improvement in mental health outcomes compared with normal advocacy care.

Background/AimsUlcerative colitis is a remitting and relapsing inflammatory bowel disorder. Current treatments are limited, and if poorly controlled, colitis may progress to colorectal cancer. Previously, Emu Oil protected the intestine in experimental models of gut damage. We aimed to determine whether Emu Oil could reduce the severity of chronic colitis and prevent the onset of neoplasia in a mouse model of colitis-associated colorectal cancer.MethodsFemale C57BL/6 mice were injected (day 0) with azoxymethane, followed by ad libitum access to three dextran sulfate sodium/water cycles (7 days of dextran sulfate sodium and 14 days of water). Mice (n = 9/group) were orally administered either water or Emu Oil (low dose 80 µL or high dose 160 µL), thrice weekly for 9 weeks. Bodyweight and disease activity index were measured daily. Colitis progression was monitored by colonoscopy on days 20, 41 and 62. At killing, tumor number and size were recorded.ResultsAzoxymethane/dextran sulfate sodium induced significant bodyweight loss (maximum 24%) which was attenuated by Emu Oil treatment (low dose days 9, 10, 14: maximum 7%; high dose days 7–15, 30–36: maximum 11%; p < 0.05). Emu Oil reduced disease activity index of azoxymethane/dextran sulfate sodium mice at most time points (maximum 20%; p < 0.05). Additionally, Emu Oil reduced colonoscopically assessed colitis severity (days 20 and 62) compared to disease controls (p < 0.05). Finally, in azoxymethane/dextran sulfate sodium mice, low-dose Emu Oil resulted in fewer small colonic tumors (p < 0.05) compared to controls.ConclusionsEmu Oil improved clinical indicators and reduced severity of colitis-associated colorectal cancer, suggesting therapeutic potential in colitis management.

Hypertrophic cardiomyopathy (HCM), characterized by a thickened, fibrotic myocardium, remains the most common cause of sudden cardiac death in young adults. Based on animal and clinical data, we hypothesized that atorvastatin would induce left ventricular (LV) mass regression.
Statin Induced Regression of Cardiomyopathy Trial (SIRCAT) was a randomized, placebo-controlled study. The primary endpoint was change in LV mass measured by cardiac magnetic resonance imaging 12 months after treatment with once-daily atorvastatin 80 mg or placebo. A key secondary endpoint was diastolic dysfunction measured echocardiographically by transmitral flow velocities. SIRCAT is registered with www.clinicaltrials.gov (NCT00317967).
Of 222 screened patients, 22 were randomized evenly to atorvastatin and placebo. The mean age was 47 ± 10 years, and 15 (68%) were male. All subjects completed the protocol. At baseline, LV masses were 197 ± 76 g and 205 ± 82 g in the placebo and atorvastatin groups, respectively. After 12 months treatment, the LV masses in the placebo and atorvastatin groups were 196 ± 80 versus 206 ± 92 g (
= 0.80), respectively. Echocardiographic indices were not different in the two groups at baseline. After 12 months, diastolic dysfunction as assessed using transmitral flow velocities E/E', A/A', and peak systolic mitral velocity showed no benefit from atorvastatin.
In patients with HCM, atorvastatin did not cause LV mass regression or improvements in LV diastolic function.

Psychological advocacy toward healing (PATH): study protocol for a randomized controlled trial
2013
Background
Domestic violence and abuse (DVA), defined as threatening behavior or abuse by adults who are intimate partners or family members, is a key public health and clinical priority. The prevalence of DVA in the United Kingdom and worldwide is high, and its impact on physical and mental health is detrimental and persistent. There is currently little support within healthcare settings for women experiencing DVA. Psychological problems in particular may be difficult to manage outside specialist services, as conventional forms of therapy such as counseling that do not address the violence may be ineffective or even harmful. The aim of this study is to assess the overall effectiveness and cost-effectiveness of a novel psychological intervention tailored specifically for survivors of DVA and delivered by domestic violence advocates based in third-sector organizations.
Methods and study design
This study is an open, pragmatic, parallel group, individually randomized controlled trial. Women ages 16 years and older experiencing domestic violence are being enrolled and randomly allocated to receive usual DVA agency advocacy support (control) or usual DVA agency support plus psychological intervention (intervention). Those in the intervention group will receive eight specialist psychological advocacy (SPA) sessions weekly or fortnightly, with two follow-up sessions, 1 month and then 3 months later. This will be in addition to any advocacy support sessions each woman receives. Women in the control group will receive usual DVA agency support but no additional SPA sessions. The aim is to recruit 250 women to reach the target sample size. The primary outcomes are psychological well-being and depression severity at 1 yr from baseline, as measured by the Clinical Outcomes in Routine Evaluation–Outcome Measure (CORE-OM) and the Patient Health Questionnaire (PHQ-9), respectively. Secondary outcome measures include anxiety, posttraumatic stress, severity and frequency of abuse, quality of life and cost-effectiveness of the intervention. Data from a subsample of women in both groups will contribute to a nested qualitative study with repeat interviews during the year of follow-up.
Discussion
This study will contribute to the evidence base for management of the psychological needs of women experiencing DVA. The findings will have important implications for healthcare commissioners and providers, as well as third sector specialist DVA agencies providing services to this client group.
