An evaluation of a common elements treatment approach for youth in Somali refugee camps.

BACKGROUND: This paper reports on: (1) an evaluation of a common elements treatment approach (CETA) developed for comorbid presentations of depression, anxiety, traumatic stress, and/or externalizing symptoms among children in three Somali refugee camps on the Ethiopian/Somali border, and (2) an evaluation of implementation factors from the perspective of staff, lay providers, and families who engaged in the intervention. METHODS: This project was conducted in three refugee camps and utilized locally validated mental health instruments for internalizing, externalizing, and posttraumatic stress (PTS) symptoms. Participants were recruited from either a validity study or from referrals from social workers within International Rescue Committee Programs. Lay providers delivered CETA to youth (CETA-Youth) and families, and symptoms were re-assessed post-treatment. Providers and families responded to a semi-structured interview to assess implementation factors. RESULTS: Children who participated in the CETA-Youth open trial reported significant decreases in symptoms of internalizing (d  =  1.37), externalizing (d  =  0.85), and posttraumatic stress (d  =  1.71), and improvements in well-being (d  =  0.75). Caregivers also reported significant decreases in child symptoms. Qualitative results were positive toward the acceptability and appropriateness of treatment, and its feasibility. CONCLUSIONS: This project is the first to examine a common elements approach (CETA: defined as flexible delivery of elements, order, and dosing) with children and caregivers in a low-resource setting with delivery by lay providers. CETA-Youth may offer an effective treatment that is easier to implement and scale-up versus multiple focal interventions. A fullscale randomized clinical trial is warranted.

Local perceptions of the impact of group interpersonal psychotherapy in rural Uganda.

BACKGROUND: This study investigated local perceptions of changes stemming from a long-standing Group Interpersonal Psychotherapy (IPT-G) program for the treatment of depression in rural Uganda. The study was conducted in a low-income, severely HIV/AIDS-affected area where in 2001 the prevalence of depression was estimated at 21% among adults. METHOD: Data were collected using free-listing and key informant qualitative interviews. A convenience sample of 60 free-list respondents was selected from among IPT-G participants, their families, and other community members from 10 Ugandan villages. Twenty-two key informants and six IPT-G facilitators were also interviewed. RESULTS: Content analysis yielded five primary categories of change in the community related to the IPT-G program: (1) improved school attendance for children; (2) improved productivity; (3) improved sanitation in communities; (4) greater cohesion among community members; and (5) reduced conflict in families. Community members and IPT-G facilitators suggested that as depression remitted, IPT-G participants became more hopeful, motivated and productive. CONCLUSION: Results suggest that providing treatment for depression in communities with high depression prevalence rates may lead to positive changes in a range of non-mental health outcomes.

Use of high-frequency ultrasound in the assessment of injectable dermal fillers.

BACKGROUND: The use of dermal fillers for enhancing lips and reducing wrinkles is currently one of the fastest growing sectors of the cosmetic surgery market. There are numerous fillers available, some are synthetic others are isolated from biological material. Once injected the fillers have a varied lifespan ranging from months to years depending upon the material, site of injection and individual response. Current assessment techniques of filler performance are mostly limited to evaluations of the skin surface topography, and not to what is happening to the filler beneath the skin surface. The aim of this work was to see if high-frequency ultrasound could be used to image and measure filler dimensions in situ. METHOD: This was a pilot study of six healthy female volunteers aged 36-53 visiting the surgical outpatients department of a hospital in Glasgow. Volunteers had been injected with filler material into their upper lip 6 months before the visit. The patients all had their upper lip scanned using high-frequency ultrasound. The subsequent images were then assessed using the scanner software to assess the dimensions of the filler. RESULTS: The filler material was clearly visible with the ultrasound and subsequently measurable in each scan. Each scan procedure was completed within a short time period meaning quantitative data could be acquired with minimum trauma to the volunteer. The scan images and data also provided valuable information for the volunteers and reinforced their perception of the fillers effect on their features. CONCLUSIONS: High-frequency ultrasound scanning provides a non-invasive, convenient and rapid technique for the assessment of filler performance. This pilot study produced three valuable pieces of information: The ultrasound can image the filler material from which quantitative measurements can be made. The technique is rapid and cost effective ...This investigation helped to reinforce the volunteer's perception of the filler effect.

The use of high-frequency diagnostic ultrasound to investigate the effect of hormone replacement therapy on skin thickness.

BACKGROUND/AIMS: Previous investigations have suggested that hormone replacement therapy (HRT) could have a positive effect on the maintenance of skin thickness post-menopause. Previous skin measurement devices have proved variable in their accuracy and ease of use. This investigation assessed the effect of HRT on the skin in a noninvasive way, using high-frequency diagnostic ultrasound. METHOD: The study was a cross-sectional observational study, carried out at a menopause and gynaecology outpatient's clinic. A total of 84 women (comprising 34 HRT users, 25 post-menopausal controls, and 25 premenopausal controls) took part in the study. Each volunteer was scanned using diagnostic ultrasound on the arm. Skin thickness measurements were made from each scan using computerised image analysis. RESULTS: Skin thickness was shown to be greater in the HRT group than in the post-menopausal controls (P<0.01). CONCLUSIONS: High-frequency diagnostic ultrasound proved to be a useful clinical tool and showed that HRT appears to help maintain skin thickness in menopause.

High-frequency ultrasound imaging of the skin during normal and hypertensive pregnancies.

BACKGROUND/AIMS: Diagnosis of preeclampsia is currently made from blood pressure measurements taken at antenatal visits (either at the hospital or in the community). The aim of this work was to see whether the presence of underlying hypertensive diseases is accompanied by changes in the skin of pregnant women, which can be visualized using high-frequency diagnostic ultrasound. METHODS: This was a prospective study of pregnant and non-pregnant, hypertensive and non-hypertensive patients visiting the outpatient department of a central London Teaching Hospital. The study group consisted of 93 women, of which 30 were non-hypertensive in the second trimester of pregnancy, 26 were non-hypertensive in the third trimester of pregnancy, 9 were hypertensive in the second trimester of pregnancy, and 14 were hypertensive in the third trimester of pregnancy. Fourteen non-pregnant women of comparable age were recruited as controls. Changes in abdominal skin thickness and also skin structure, as analysed by fractal image analysis, was assessed in each patient. RESULTS: In a normal pregnancy, abdominal skin gets thinner as pregnancy progresses. In hypertensive patients, the skin thickness did not appear to alter. Image analysis of abdominal skin scans showed that the skin of non-hypertensive pregnant women and non-pregnant women are different. Whereas the analysis of hypertensive pregnant women and non-pregnant women showed they were the same. CONCLUSIONS: The data used to compare the groups indicates that if the abdominal skin of the patient does not get thinner as the pregnancy progresses there is an indication that the patient may be hypertensive. The fractal data comparing the groups indicates the following when comparing a patient's fractal signature with the non-pregnant control data: If the abdominal fractal for a pregnant woman is similar to the control group, there is an indication that the patient is hypertensive. It is difficult to predict hypertension in patients, and it is possible that a patient could develop severe preeclampsia between visits to the antenatal clinics. Therefore, if the high-frequency ultrasound scanner can pick up potential hypertensives early in pregnancy, these women could be identified as potentially high risk.

Communicating across cultures: improving translation to improve complex emergency program effectiveness.

Translation is a vital activity in Complex Emergencies (CEs) in which the responders and the affected populations do not share the same language or culture. This particularly applies to CEs in developing countries in which a lack of local resources usually results in the importation of foreign aid workers. This paper describes many of the common issues surrounding translation that can affect CE response effectiveness, issues that frequently are not appreciated by aid workers, including clinicians. The authors describe how these issues can arise, their effects, and outline approaches to addressing them.

Age, gender, and other predictors of the wasting syndrome among HIV-1-infected injecting drug users.

We conducted a study to identify predictors of the wasting syndrome among human immunodeficiency virus 1 (HIV-1)-seropositive injecting drug users. We enrolled 113 cases (defined as an unexplained loss of > 10% baseline weight) and 226 controls (defined as < 5% weight loss or any weight gain) from a HIV-1-seropositive cohort of injecting drug users (N = 630) into a nested case-control study. Crude predictors of wasting included: older age [odds ratio (OR) for a 1-year difference = 1.06], female gender (OR = 1.66), more years spent injecting drugs (OR for 1-year difference = 1.05), presence of diarrhea (OR = 3.78), lower percentage of CD4 T-lymphocytes (OR for 10-unit difference = 0.73), and higher log beta 2-microglobulin concentration (OR for 1 log difference = 11.3). After adjusting for CD4 cell level, beta 2-microglobulin concentration, diarrhea, gender, length and frequency of drug use, age, the presence of thrush, and education, independent predictors of weight loss in HIV-seropositive injecting drug users were female gender (OR = 2.23) and increasing age (OR for 1-year difference = 1.06). Frequency and duration of drug use were not strongly associated with the odds of developing wasting syndrome in this HIV-1-seropositive cohort. These data indicate that HIV wasting syndrome in injecting drug users is distinct from complications of drug use.
