Intensive Short-Term Dynamic Psychotherapy Trial Therapy: Effectiveness and Role of "Unlocking the Unconscious".

This study examined the effects of trial therapy interviews using intensive short-term dynamic psychotherapy with 500 mixed sample, tertiary center patients. Furthermore, we investigated whether the effect of trial therapy was larger for patients who had a major unlocking of the unconscious during the interview compared with those who did not. Outcome measures were the Brief Symptom Inventory (BSI) and the Inventory of Interpersonal Problems (IIP), measured at baseline and at 1-month follow-up. Significant outcome effects were observed for both the BSI and the IIP with small to moderate preeffect/posteffect sizes, Cohen's d = 0.52 and 0.23, respectively. Treatment effects were greater in patients who had a major unlocking of the unconscious compared with those who did not. The trial therapy interview appears to be beneficial, and its effects may relate to certain therapeutic processes. Further controlled research is warranted.

Recommendations on screening for high blood pressure in Canadian adults.

OBJECTIVE: To provide recommendations on screening for hypertension in adults aged 18 years and older without previously diagnosed hypertension. QUALITY OF EVIDENCE: Evidence was found through a systematic search of MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews (EBM Reviews), from January 1985 to September 2011. Study types were limited to randomized controlled trials, systematic reviews, and observational studies with control groups. MAIN MESSAGE: Three strong recommendations were made based on moderate-quality evidence. It is recommended that blood pressure measurement occur at all appropriate primary care visits, according to the current techniques described in the Canadian Hypertension Education Program recommendations for office and ambulatory blood pressure measurement. The Canadian Hypertension Education Program criteria for assessment and diagnosis of hypertension should be applied for people found to have elevated blood pressure. CONCLUSION: After review of the most recent evidence, the Canadian Task Force on Preventive Health Care continues to recommend blood pressure measurement during regular physician visits.

Body mass index and risk of cardiovascular disease, cancer and all-cause mortality.

OBJECTIVES: To determine the dose-response relationship between body mass index (BMI) and cause-specific mortality among Canadian adults. METHODS: The sample includes 10,522 adults 18-74 years of age who participated in the Canadian Heart Health Surveys (1986-1995). Participants were divided into 5 BMI categories (< 18.5, 18.5-24.9, 25-29.9, 30-34.9, and > or = 35 kg/m2). Multivariate-adjusted (age, sex, exam year, smoking status, alcohol consumption and education) hazard ratios for all-cause, cardiovascular disease (CVD) and cancer mortality were estimated using Cox proportional hazards regression. RESULTS: There were 1,149 deaths (402 CVD; 412 cancer) over an average of 13.9 years (range 0.5 to 19.1 years), and the analyses are based on 145,865 person-years. The hazard ratios (95% CI) across successive BMI categories for all-cause mortality were 1.25 (0.83-1.90), 1.00 (reference), 1.06 (0.92-1.22), 1.27 (1.07-1.51) and 1.65 (1.29-2.10). The corresponding hazard ratios for CVD mortality were 1.30 (0.60-2.83), 1.00 (reference), 1.57 (1.22-2.01), 1.72 (1.27-2.33) and 2.09 (1.35-3.22); and for cancer, the hazard ratios were 1.02 (0.48-2.21), 1.00 (reference), 1.14 (0.90-1.44), 1.34 (1.01-1.78) and 1.82 (1.22-2.71). There were significant linear trends across BMI categories for all-cause (p = 0.0001), CVD (p < 0.0001) and cancer mortality (p = 0.003). CONCLUSIONS: The results demonstrate significant relationships between BMI and mortality from all causes, CVD and cancer. The increased risk of all-cause, CVD and cancer mortality associated with an elevated BMI was significant at levels above 30 kg/m2; however, overweight individuals (BMI 25-29.9 kg/m2) also had an approximately 60% higher risk of CVD mortality.

Changes in the rates of awareness, treatment and control of hypertension in Canada over the past two decades.

BACKGROUND: Analyses of medication databases indicate marked increases in prescribing of antihypertensive drugs in Canada over the past decade. This study was done to examine the trends in the prevalence of hypertension and in control rates in Canada between 1992 and 2009. METHODS: Three population-based surveys, the 1986-1992 Canadian Heart Health Surveys, the 2006 Ontario Survey on the Prevalence and Control of Hypertension and the 2007-2009 Canadian Health Measures Survey, collected self-reported health information from, and measured blood pressure among, community-dwelling adults. RESULTS: The population prevalence of hypertension was stable between 1992 and 2009 at 19.7%-21.6%. Hypertension control improved from 13.2% (95% confidence interval [CI] 10.7%-15.7%) in 1992 to 64.6% (95% CI 60.0%-69.2%) in 2009, reflecting improvements in awareness (from 56.9% [95% CI 53.1%-60.5%] in 1992 to 82.5% [95% CI 78.5%-86.0%] in 2009) and treatment (from 34.6% [95% CI 29.2%-40.0%] in 1992 to 79.0% [95% CI 71.3%-86.7%] in 2009) among people with hypertension. The size of improvements in awareness, treatment and control were similar among people who had or did not have cardiovascular comorbidities Although systolic blood pressures among patients with untreated hypertension were similar between 1992 and 2009 (ranging from 146 [95% CI 145-147] mm Hg to 148 [95% CI 144-151] mm Hg), people who did not have hypertension and patients with hypertension that was being treated showed substantially lower systolic pressures in 2009 than in 1992 (113 [95% CI 112-114] v. 117 [95% CI 117-117] mm Hg and 128 [95% CI 126-130] v. 145 [95% CI 143-147] mm Hg). INTERPRETATION: The prevalence of hypertension has remained stable among community-dwelling adults in Canada over the past two decades, but the rates for treatment and control of hypertension have improved markedly during this time.

Estimating the impact of expanded access to antiretroviral therapy on maternal, paternal and double orphans in sub-Saharan Africa, 2009-2020.

BACKGROUND: HIV/AIDS has orphaned 11.6 million children in sub-Saharan Africa. Expanded antiretroviral therapy (ART) use may reduce AIDS orphanhood by decreasing adult mortality and population-level HIV transmission. METHODS: We modeled two scenarios to measure the impact of adult ART use on the incidence of orphanhood in 10 sub-Saharan African countries, from 2009 to 2020. Demographic model data inputs were obtained from cohort studies, UNAIDS, UN Population Division, WHO and the US Census Bureau. RESULTS: Compared to current rates of ART uptake, universal ART access averted 4.37 million more AIDS orphans by year 2020, including 3.15 million maternal, 1.89 million paternal and 0.75 million double orphans. The number of AIDS orphans averted was highest in South Africa (901.71 thousand) and Nigeria (839.01 thousand), and lowest in Zimbabwe (86.96 thousand) and Côte d'Ivoire (109.12 thousand). CONCLUSION: Universal ART use may significantly reduce orphanhood in sub-Saharan Africa.

The prevalence of menstrual pain and associated risk factors among Iranian women.

AIM: To estimate the prevalence of dysmenorrhea in Iranian women and investigate associated risk factors. MATERIAL & METHODS: In a cross-sectional study in Tehran, Iran in 2007, 381 women (81% response rate, age 16-56 years) were selected through a stratified random sample of 22 different districts and completed a questionnaire about dysmenorrhea. Descriptive statistics, spearman rank correlation statistic, and ordinal logistic regression models were used. Confounding and effect-modification were explored for each association. RESULTS: The prevalence of no, mild, moderate, and severe menstrual pain was 10%, 41%, 28%, and 22%, respectively. Older age and high intake of fruits and vegetables were protective factors for menstrual pain while women with family history of dysmenorrhea, higher stress and depression tended to have more severe pain. Body mass index, parity, smoking, and physical activity were not significantly associated with dysmenorrhea after controlling for potential confounding factors and effect modifiers. CONCLUSION: Menstrual pain is a common complaint in Iranian women. The inverse association between fruit and vegetable intake and dysmenorrhea, and reduction of stress and depression need to be further explored and considered in terms of recommendation to reduce dysmenorrhea.

Does ratification of human-rights treaties have effects on population health?

Human-rights treaties indicate a country's commitment to human rights. Here, we assess whether ratification of human-rights treaties is associated with improved health and social indicators. Data for health (including HIV prevalence, and maternal, infant, and child [<5 years] mortalities) and social indicators (child labour, human development index, sex gap, and corruption index), gathered from 170 countries, showed no consistent associations between ratification of human-rights treaties and health or social outcomes. Established market economy states had consistently improved health compared with less wealthy settings, but this was not associated with treaty ratification. The status of treaty ratification alone is not a good indicator of the realisation of the right to health. We suggest the need for stringent requirements for ratification of treaties, improved accountability mechanisms to monitor compliance of states with treaty obligations, and financial assistance to support the realisation of the right to health.

Water and sanitation infrastructure for health: The impact of foreign aid.

BACKGROUND: The accessibility to improved water and sanitation has been understood as a crucial mechanism to save infants and children from the adverse health outcomes associated with diarrheal disease. This knowledge stimulated the worldwide donor community to develop a specific category of aid aimed at the water and sanitation sector. The actual impact of this assistance on increasing population access to improved water and sanitation and reducing child mortality has not been examined. METHODS: We performed a country-level analysis of the relationship between water and sanitation designated official development assistance (WSS-ODA) per capita, water and sanitation coverage, and infant and child mortality in low-income countries as defined by the World Bank. We focused our inquiry to aid effectiveness since the establishment of the Millennium Development Goals (MDGs). RESULTS: Access to improved water has consistently improved since 2002. Countries receiving the most WSS-ODA ranged from odds ratios of 4 to 18 times more likely than countries in the lowest tertile of assistance to achieve greater gains in population access to improved water supply. However, while there were modestly increased odds of sanitation access, these were largely non-significant. The countries with greatest gains in sanitation were 8-9 times more likely to have greater reductions in infant and child mortality. CONCLUSIONS: Official development assistance is importantly impacting access to safe water, yet access to improved sanitation remains poor. This highlights the need for decision-makers to be more intentional with allocating WSS-ODA towards sanitation projects.

Health and historical levels of freedom.

BACKGROUND: The link between political freedom and health is unclear. We aimed to determine the association by exploring the relationship of historical and cumulative freedom levels with important health outcomes. METHODS: We obtained countrywide health indicators for life expectancy, infant mortality, maternal mortality ratio, % low birth weight babies, Gini coefficient (a measure of wealth inequality) and various markers of freedom based on political rights and civil liberties. We applied multivariable logistic regression to examine the association between health indicators and within-country years of freedom as determined by Freedom House rankings. RESULTS: The total proportion of free years from 1972-2005, the duration of current freedom level, and the Gini coefficient show independent positive associations with health indicators, which remain after the adjustment for national wealth, total government expenditure, and spending on health. Countries identified as having high total proportion of free years demonstrated significantly better health outcomes than countries with low levels of freedom (life expectancy, Odds Ratio [OR] 7.2, 95% Confidence Interval [CI], 2.3-22.6, infant mortality OR 19.6, 95% CI, 5.6-67.7, maternal mortality ratio, OR 24.3, 95% CI, 6.2-94.9, and % low birth weight babies OR 3.8, 95% CI, 1.4-10.8). This was also the case for infant mortality (OR 3.4, 95% CI, 1.0-8.4), maternal mortality ratio (OR 4.0, 95% CI, 1.2-12.8), and % low birth weight babies (OR 2.6, 95% CI, 1.0-6.6) among countries considered as having medium levels of freedom. INTERPRETATION: We found strong associations between country-level freedom and important health outcomes. The cumulative level of freedom over time shows stronger associations with all health indicators than the duration of current freedom level.

Reporting of informed consent, standard of care and post-trial obligations in global randomized intervention trials: a systematic survey of registered trials.

OBJECTIVE: Ethical guidelines are designed to ensure benefits, protection and respect of participants in clinical research. Clinical trials must now be registered on open-access databases and provide details on ethical considerations. This systematic survey aimed to determine the extent to which recently registered clinical trials report the use of standard of care and post-trial obligations in trial registries, and whether trial characteristics vary according to setting. METHODS: We selected global randomized trials registered on http://www.clinicaltrials.gov and http://www.controlled-trials.com. We searched for intervention trials of HIV/AIDS, malaria, and tuberculosis from 9 October 2004, the date of the most recent version of the Helsinki Declaration, to 10 April 2007. RESULTS: We collected data from 312 trials. Fifty-eight percent (58%, 95% CI = 53 to 64) of trial protocols report informed consent. Fifty-eight percent (58%, 95% CI = 53 to 64) of trials report active controls. Almost no trials (1%, 95% CI = 0.5 to 3) mention post-trial provisions. Most trials measure surrogate outcomes. Twenty percent (20%, 95% CI = 16 to 25) of trials measure patient-important outcomes, such as death; and the odds that these outcomes are in a low income country are five times greater than for a developed country (odds ratio (OR) 5.03, 95% CI = 2.70 to 9.35, p = < 0.001). Pharmaceutical companies are involved in 28% (CI = 23 to 33) of trials and measure surrogate outcomes more often than nonpharmaceutical companies (OR 2.45, 95% CI = 1.18 to 5.09, p = 0.31). CONCLUSION: We found a large discrepancy in the quality of reporting and approaches used in trials in developing settings compared to wealthier settings.

Prevalence of mental disorders among children exposed to war: a systematic review of 7,920 children.

Worldwide, millions of children are affected by armed conflict. However, data on the prevalence of mental disorders among these children is sparse. We aimed to determine the prevalence of mental disorders among children affected by war using a systematic review and meta-regression analysis. We systematically reviewed existing literature to identify studies on prevalence of post-traumatic stress disorder (PTSD), anxiety, depression and psychosis among children exposed to armed conflict. We searched electronic databases and references listed in studies to obtain eligible studies. We pooled studies using the random-effects method and explored heterogeneity using meta-regression analysis. Seventeen studies met our inclusion criteria. Studies included 7,920 children. Sample sizes ranged from 22 to 2,976. Four studies were conducted during a conflict and others during post-conflict. All the studies reported PTSD as the primary outcome ranging from 4.5 to 89.3%, with an overall pooled estimate of 47% (9% CI: 35-60%, I2 = 98%). Meta-analysis heterogeneity was attributable to study location (OR 1.33, 95% CI: 1.27-1.41), method of measurement (OR 1.36, 95% CI: 1.29-1.44) and duration since exposure to war (coefficient 0.17, 95% CI: 0.94-0.25). In addition, four studies reported elevated depression that allowed pooling (43%, 95% CI: 31-55%) and three studies reported elevated anxiety disorders allowing pooling (27%, 95% CI: 21-33%). Our systematic review suggests a higher prevalence rate of mental disorders among children exposed to conflict than among the general population. Given the number of current conflicts, there is a paucity of information regarding mental disorders among children affected by war.

Widespread rape does not directly appear to increase the overall HIV prevalence in conflict-affected countries: so now what?

BACKGROUND: Sub-Saharan Africa (SSA) is severely affected by HIV/AIDS and conflict. Sexual violence as a weapon of war has been associated with concerns about heightened HIV incidence among women. Widespread rape by combatants has been documented in Burundi, Sierra Leone, Rwanda, Democratic Republic of Congo, Liberia, Sudan and Uganda. To examine the assertion that widespread rape may not directly increase HIV prevalence at the population level, we built a model to determine the potential impact of varying scenarios of widespread rape on HIV prevalence in the above seven African countries. DISCUSSION: Our findings show that even in the most extreme situations, where 15% of the female population was raped, where HIV prevalence among assailants was 8 times the country population prevalence, and where the HIV transmission rate was highest at 4 times the average high rate, widespread rape increased the absolute HIV prevalence of these countries by only 0.023%. These projections support the finding that widespread rape in conflict-affected countries in SSA has not incurred a major direct population-level change in HIV prevalence. However, this must not be interpreted to say that widespread rape does not pose serious problems to women's acquisition of HIV on an individual basis or in specific settings. Furthermore, direct and indirect consequences of sexual violence, such as physical and psychosocial trauma, unwanted pregnancies, and stigma and discrimination cannot be understated. SUMMARY: The conclusions of this article do not significantly change current practices in the field from an operational perspective. Proper care and treatment must be provided to every survivor of rape regardless of the epidemiological effects of HIV transmission at the population level. Sexual violence must be treated as a protection issue and not solely a reproductive health and psychosocial issue. It is worth publishing data and conclusions that could be misconstrued and may not make much of a programmatic difference in the field. Data, if collected, analysed and interpreted carefully, help to improve our understanding of complicated and nuanced situations. Ultimately, our understanding of what the outcomes of such interventions can achieve will be more realistic. It also helps decision-makers prioritise their funding and interventions.

Medication persistence rates and factors associated with persistence in patients following stroke: a cohort study.

BACKGROUND: Medication nonadherence can be as high as 50% and results in suboptimal patient outcomes. Stroke patients in particular can benefit from pharmacotherapy for thrombosis, hypertension, and dyslipidemia but are at high risk for medication nonpersistence. METHODS: Patients who were admitted to the Queen Elizabeth II Health Sciences Centre in Halifax, Nova Scotia, with stroke between January 1, 2001 and December 31, 2002 were analyzed. Data collected were pre-stroke function, stroke subtype, stroke severity, patient outcomes, and medication use at discharge, and six and 12 months post discharge. Medication persistence at six and 12 months and the factors associated with nonpersistence at six months were examined using multivariable stepwise logistic regression. RESULTS: At discharge, 420 patients (mean age 68.2 years, 55.7% male) were prescribed an average of 6.4 medications and mean prescription drug cost was $167 monthly. Antihypertensive (91%) and antithrombotic (96%) drug use at discharge were frequent, antilipidemic (73%) and antihyperglycemic (25%) drug use were less common. Self-reported persistence at six and 12 months after stroke was high (> 90%) for all categories. In the multivariable model of medication nonpersistence at six months, people aged 65 to 79 years were less likely to be nonpersistent with antihypertensive medications than people aged 80 years or more (Odds ratio (OR) 0.11, 95% Confidence Interval (CI) 0.03-0.39). Monthly drug costs of < $90 or $90-199.99 were associated with greater nonpersistence, compared to monthly drug costs > or =$200 (OR 6.74, 95% CI 1.32-34.46 for < $90; OR 5.25, 95% CI 1.14-24.25 for $90-199.99). For the antithrombotic drug category, people aged 65 to 79 years were less likely to be nonpersistent than people aged 80 years or more (OR 0.23, 95% CI 0.06-0.81), and people who were disabled before admission were more likely to be nonpersistent than those not disabled (OR 7.01, 95% CI 1.66-29.58). CONCLUSION: Patients reported high medication persistence rates six and 12 months after stroke. Identification of factors associated with nonpersistence (such as older age and prior disability) will help predict which patients are at higher risk for discontinuing their medications.

Sexual slavery without borders: trafficking for commercial sexual exploitation in India.

Trafficking in women and children is a gross violation of human rights. However, this does not prevent an estimated 800 000 women and children to be trafficked each year across international borders. Eighty per cent of trafficked persons end in forced sex work. India has been identified as one of the Asian countries where trafficking for commercial sexual exploitation has reached alarming levels. While there is a considerable amount of internal trafficking from one state to another or within states, India has also emerged as a international supplier of trafficked women and children to the Gulf States and South East Asia, as well as a destination country for women and girls trafficked for commercial sexual exploitation from Nepal and Bangladesh. Trafficking for commercial sexual exploitation is a highly profitable and low risk business that preys on particularly vulnerable populations. This paper presents an overview of the trafficking of women and girls for sexual exploitation (CSE) in India; identifies the health impacts of CSE; and suggest strategies to respond to trafficking and related issues.

Cultural adaptation and validation of the Chinese version of the expanded prostate cancer index composite.

AIM: The expanded prostate cancer index composite (EPIC) is a widely adopted instrument for the quality of life of patients with prostate cancer. We aimed to create a Chinese version of EPIC to further research in the Chinese-speaking population. METHODS: A prototype was created by forward-backward translations and revisions. During cultural adaptation, 15 participants were interviewed after they had completed the prototype. A few issues highlighted included confusion related to the question format, subject non-familiarity with the Chinese term for "hot flashes," and the use of the Chinese term for "breast" as a strictly female body part. A pilot version was created based on the cultural adaptation findings. Validation of the pilot version was performed by having 50 participants complete the Chinese EPIC and EORTC QLQ-c30 twice within a 4-week period. Test-retest reliability (Pearson's correlations and difference distribution) and internal consistency (Cronbach's α) were measured using SAS version 9.4. RESULTS: Test-retest reliability values for the urinary, bowel, sexual and hormone domains were 0.71, 0.51, 0.51 and 0.66, respectively; subscale test-retest reliability ranged between 0.29 and 0.82. Internal consistency for domains was good with Cronbach's α ranging from 0.76 to 0.78 for the initial test and 0.67 to 0.85 for the retest. The performance of this version of EPIC was comparable to the validated EORTC QLQ-C30. CONCLUSION: The EPIC questionnaire was successfully translated into Chinese and was culturally adapted. The resultant Chinese version has high reliability and validity and will be an important tool for research on quality of life in the Chinese population.
