Methodological approaches to situational analysis in global mental health: a scoping review.

Global inequity in access to and availability of essential mental health services is well recognized. The mental health treatment gap is approximately 50% in all countries, with up to 90% of people in the lowest-income countries lacking access to required mental health services. Increased investment in global mental health (GMH) has increased innovation in mental health service delivery in LMICs. Situational analyses in areas where mental health services and systems are poorly developed and resourced are essential when planning for research and implementation, however, little guidance is available to inform methodological approaches to conducting these types of studies. This scoping review provides an analysis of methodological approaches to situational analysis in GMH, including an assessment of the extent to which situational analyses include equity in study designs. It is intended as a resource that identifies current gaps and areas for future development in GMH. Formative research, including situational analysis, is an essential first step in conducting robust implementation research, an essential area of study in GMH that will help to promote improved availability of, access to and reach of mental health services for people living with mental illness in low- and middle-income countries (LMICs). While strong leadership in this field exists, there remain significant opportunities for enhanced research representing different LMICs and regions.

A rapid questionnaire assessment of environmental exposures to pregnant women in the INTERGROWTH-21st Project.

Impaired fetal growth and preterm birth are the leading causes of neonatal and infant mortality worldwide and there is a growing scientific literature suggesting that environmental exposures during pregnancy may play a causal role in these outcomes. Our purpose was to assess the environmental exposure of the Fetal Growth Longitudinal Study (FGLS) participants in the multinational INTERGROWTH-21(st) Project. First, we developed a tool that could be used internationally to screen pregnant women for such exposures and administered it in eight countries on a subsample (n = 987) of the FGLS participants. The FGLS is a study of fetal growth among healthy pregnant women living in relatively affluent areas, at low risk of adverse pregnancy outcomes and environmental exposures. We confirmed that most women were not exposed to major environmental hazards that could affect pregnancy outcomes according to the protocol's entry criteria. However, the instrument was able to identify some women that reported various environmental concerns in their homes such as peeling paint, high residential density (>1 person per room), presence of rodents or cockroaches (hence the use of pesticides), noise pollution and safety concerns. This screening tool was therefore useful for the purposes of the project and can be used to ascertain environmental exposures in studies in which the primary aim is not focused on environmental exposures. The instrument can be used to identify subpopulations for more in-depth assessment, (e.g. environmental and biological laboratory markers) to pinpoint areas requiring education, intervention or policy change.

Obstetric ultrasound scanning by local health workers in a refugee camp on the Thai-Burmese border.

OBJECTIVES: Ultrasound examination of the fetus is a powerful tool for assessing gestational age and detecting obstetric problems but is rarely available in developing countries. The aim of this study was to assess the intraobserver and interobserver agreement of fetal biometry by locally trained health workers in a refugee camp on the Thai-Burmese border. METHODS: One expatriate doctor and four local health workers participated in the study, which included examinations performed on every fifth pregnant woman with a singleton pregnancy between 16 and 40 weeks' gestation, and who had undergone an early dating ultrasound scan, attending the antenatal clinic in Maela refugee camp. At each examination, two examiners independently measured biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC) and femur length (FL), with one of the examiners obtaining duplicate measurements of each parameter. Intraobserver measurement error was assessed using the intraclass correlation coefficient (ICC) and interobserver error was assessed by the Bland and Altman 95% limits of agreement method. RESULTS: A total of 4188 ultrasound measurements (12 per woman) were obtained in 349 pregnancies at a median gestational age of 27 (range, 16-40) weeks in 2008. The ICC for BPD, HC, AC and FL was greater than 0.99 for all four trainees and the doctor (range, 0.996-0.998). For gestational ages between 18 and 24 weeks, interobserver 95% limits of agreement corresponding to differences in estimated gestational age of less than +/- 1 week were calculated for BPD, HC, AC and FL. Measurements by local health workers showed high levels of agreement with those of the expatriate doctor. CONCLUSIONS: Locally trained health workers working in a well organized unit with ongoing quality control can obtain accurate fetal biometry measurements for gestational age estimation. This experience suggests that training of local health workers in developing countries is possible and could allow effective use of obstetric ultrasound imaging.

Clinical aspects of depression.

In recent years, clinicians and epidemiologists have examined the differences between depressed patients in primary care and psychiatric settings. Although evidence to support antidepressant efficacy is largely derived from studies of major depression, many patients in primary care settings fall into "nonmajor" depression diagnostic categories. In deciding when to initiate treatment, functional change may be even more important than discrete symptom profiles. Recognizing and treating depression as a comorbid condition in patients with other medical illnesses represents an additional challenge for the primary care physician. Variations in the clinical presentation of depression based on gender, age, culture, or personality must also be considered.

Assessment of personality disorders in anorexia nervosa and bulimia nervosa. A comparison of self-report and structured interview methods.

Interest in assessing Personality Disorders (PDs) in association with anorexia nervosa (AN) and bulimia nervosa (BN) has been accompanied by the development of several structured interview and self-report measures. In an attempt to see how the self-report Millon Clinical Multiaxial Inventory (MCMI-II) compared with the Structured Clinical Interview for DSM-III-R (SCID-II) in the assessment of PDs, we gave both instruments to 43 inpatients with a diagnosis of AN or BN. Correlation coefficient values for both categorical and dimensional comparisons were generally less than .4. Although comparable rates of positive PDs occurred for each of the three clusters (A: 30.2% vs. 34.9%, B: 25.6% vs. 18.6%, and C: 62.8% vs. 81.4% for SCID-II vs. MCMI-II), agreement for individual diagnosis and individual subjects was poor. In conclusion, the MCMI-II did not prove to be a reliable instrument for assessing axis II PDs in patients with AN and BN when compared with the SCID-II.

Factors complicating the diagnosis of depression in cerebrovascular disease, Part II--Neurological deficits and various assessment methods.

Neurological deficits associated with cerebrovascular disease such as aphasia, dementia, anosognosia and aprosodia may impair the ability to express or experience depressive symptoms. Identification of depression in the absence of verbal report on subjective mood state is a difficult task. The value of various diagnostic methods including depressive rating scales, standard psychiatric interviews and biological variables in the diagnosis of depression in cerebrovascular disease is considered. This review concludes by focusing on the deficiencies of existing approaches in the diagnostic assessment of depression in patients with severe communication and comprehension deficits and emphasizes the importance of devising a standard diagnostic method with less reliance on verbal responses.

A controlled assessment of direct intraperitoneal insemination.

OBJECTIVE: To test the efficacy of direct intraperitoneal (IP) insemination and its effect on cell-mediated immunity. DESIGN: A prospective trial with each couple having one treatment (insemination) cycle and one control (timed intercourse) cycle performed in random order with the same ovulation stimulation in both cycles. SETTING: Secondary and tertiary referral fertility clinics; university teaching hospital. PATIENTS: Twenty-six infertile couples. Excluding pregnancy, only one couple did not complete the two cycles. INTERVENTIONS: Ovulation induction in both cycles. Intraperitoneal insemination in the insemination cycles. MAIN OUTCOME MEASURES: These were pregnancy rate (treatment versus control) and mixed lymphocyte response (MLR) sensitivity (before and after direct IP insemination treatment). RESULTS: There were four control and no treatment pregnancies. This was not a significant difference (odds ratio). Mixed lymphocyte responses in fertile subjects did not change during the menstrual cycle (Wilcoxon). There was no significant increase in MLR sensitivity to partner's cells after direct IP insemination treatment. CONCLUSIONS: This controlled study found no benefit from direct IP insemination in terms of pregnancies over control cycles. There was no evidence that direct IP insemination had increased cell-mediated immune response sensitivity to husband's cells.
