Report from the CDC: mental health of women in postwar Afghanistan

More than two decades of war and a culture that has denied women freedom of movement, access to healthcare, and education have affected the mental health status of Afghan women more than that of men. In 2002, the Centers for Disease Control and Prevention (CDC) conducted a national population-based mental health survey in Afghanistan. The prevalence of symptoms of depression was 73% (standard error [SE] 8.15) and 59% (SE 5.59), of symptoms of anxiety was 84% (SE 2.98) and 59% (SE 8.65), and of posttraumatic stress disorder (PTSD) was 48% (SE 6.19) and 32% (SE 4.22) for female and male respondents, respectively. Mean scores for social functioning were lower for women (52.00 [SE 2.77]) than for men (66.63 [SE 3.92]). Women had significantly lower mental health status and poorer social functioning than did men. Results of our survey underscore the need for financial donors and healthcare planners to address the current lack of mental healthcare resources, facilities, and trained mental healthcare professionals in Afghanistan and to establish mental health services directed at the specific needs of women. This study highlights the negative impact that war, restrictions in freedoms, and socioeconomic hardship have had on the mental health and social functioning of women in Afghanistan.     

Suicidal Ideation and Mental Health of Bhutanese Refugees in the United States

Refugee agencies noticed a high number of suicides among Bhutanese refugees resettled in the United States between 2009 and 2012. We aimed to estimate prevalence of mental health conditions and identify factors associated with suicidal ideation among Bhutanese refugees. We conducted a stratified random cross-sectional survey and collected information on demographics, mental health conditions, suicidal ideation, and post-migration difficulties. Bivariate logistic regressions were performed to identify factors associated with suicidal ideation. Prevalence of mental health conditions were: depression (21 %), symptoms of anxiety (19 %), post-traumatic stress disorder (4.5 %), and suicidal ideation (3 %), significant risk factors for suicidal ideation included: not being a provider of the family; perceiving low social support; and having symptoms of anxiety and depression. These findings suggest that Bhutanese refugees in the United States may have a higher burden of mental illness relative to the US population and may benefit from mental health screening and treatment. Refugee communities and service providers may benefit from additional suicide awareness training to identify those at highest risk.     

Protective effect of bixin on cisplatin-induced genotoxicity in PC12 cells

Bixin is the main carotenoid found in annatto seeds (Bixa orellana L.) and is responsible for their reddish-orange color. The antioxidant properties of this compound are associated with its ability to scavenge free radicals, which may reduce damage and protect tissues against toxicity caused by anticancer drugs such as cisplatin. In this study, the genotoxicity and antigenotoxicity of bixin on cisplatin-induced toxicity in PC12 cells was assessed. Cytotoxicity was evaluated using the MTT assay, mutagenicity, genotoxicity, and protective effect of bixin were evaluated using the micronucleus test and comet assay. PC12 cells were treated with bixin (0.05, 0.08, and 0.10μg/mL), cisplatin (0.1μg/mL) or a combination of both bixin and cisplatin. Bixin was neither cytotoxic nor genotoxic compared to the controls. In the combined treatment bixin significantly reduced the percentage of DNA in tail and the frequency of micronuclei induced by cisplatin. This result suggests that bixin can function as a protective agent, reducing cisplatin-induced DNA damage in PC12 cells, and it is possible that this protection could also extend to neuronal cells. Further studies are being conducted to better understand the mechanisms involved in the activity of this protective agent prior to using it therapeutically.     

Polymorphisms in arsenic(+III oxidation state) methyltransferase (AS3MT) predict gene expression of AS3MT as well as arsenic metabolism

Background

Arsenic (As) occurs as monomethylarsonic acid (MMA) and dimethylarsinic acid (DMA) in humans, and the methylation pattern demonstrates large interindividual differences. The fraction of urinary MMA is a marker for susceptibility to As-related diseases.

Objectives

We evaluated the impact of polymorphisms in five methyltransferase genes on As metabolism in two populations, one in South America and one in Southeast Asia. The methyltransferase genes were arsenic(+III oxidation state) methyltransferase (AS3MT), DNA-methyltransferase 1a and 3b (DNMT1a and DNMT3b, respectively), phosphatidylethanolamine N-methyltransferase (PEMT), and betaine-homocysteine methyltransferase (BHMT). AS3MT expression was analyzed in peripheral blood.

Methods

Subjects were women exposed to As in drinking water in the Argentinean Andes [n = 172; median total urinary As (U-As), 200 μg/L] and in rural Bangladesh (n = 361; U-As, 100 μg/L; all in early pregnancy). Urinary As metabolites were measured by high-pressure liquid chromatography/inductively coupled plasma mass spectrometry. Polymorphisms (n = 22) were genotyped with Sequenom, and AS3MT expression was measured by quantitative real-time polymerase chain reaction using TaqMan expression assays.

Results

Six AS3MT polymorphisms were significantly associated with As metabolite patterns in both populations (p ≤ 0.01). The most frequent AS3MT haplotype in Bangladesh was associated with a higher percentage of MMA (%MMA), and the most frequent haplotype in Argentina was associated with a lower %MMA and a higher percentage of DMA. Four polymorphisms in the DNMT genes were associated with metabolite patterns in Bangladesh. Noncoding AS3MT polymorphisms affected gene expression of AS3MT in peripheral blood, demonstrating that one functional impact of AS3MT polymorphisms may be altered levels of gene expression.

Conclusions

Polymorphisms in AS3MT significantly predicted As metabolism across these two very different populations, suggesting that AS3MT may have an impact on As metabolite patterns in populations worldwide.     

Zinc supplementation decreases incidence of infections in the elderly: effect of zinc on generation of cytokines and oxidative stress

BACKGROUND: Zinc deficiency, cell-mediated immune dysfunction, susceptibility to infections, and increased oxidative stress have been observed in elderly subjects (ie, those >55 y old). Zinc is an effective antiinflammatory and antioxidant agent. OBJECTIVES: The primary objective was to determine the effect of zinc on the incidence of total infections in healthy elderly subjects. The secondary objective was to determine the effect of zinc on cytokines and oxidative stress markers. DESIGN: A randomized, double-blind, placebo-controlled trial of zinc supplementation was conducted in elderly subjects. Fifty healthy subjects of both sexes aged 55-87 y and inclusive of all ethnic groups were recruited for this study from a senior center. The zinc-supplemented group received zinc gluconate (45 mg elemental Zn/d) orally for 12 mo. Incidence of infections during the supplementation period was documented. The generation of inflammatory cytokines, T helper 1 and T helper 2 cytokines, and oxidative stress markers and the plasma concentrations of zinc were measured at baseline and after supplementation. RESULTS: Compared with a group of younger adults, at baseline the older subjects had significantly lower plasma zinc, higher ex vivo generation of inflammatory cytokines and interleukin 10, and higher plasma oxidative stress markers and endothelial cell adhesion molecules. The incidence of infections and ex vivo generation of tumor necrosis factor alpha and plasma oxidative stress markers were significantly lower in the zinc-supplemented than in the placebo group. Plasma zinc and phytohemagglutin-induced interleukin 2 mRNA in isolated mononuclear cells were significantly higher in the zinc-supplemented than in the placebo group. CONCLUSIONS: After zinc supplementation, the incidence of infections was significantly lower, plasma zinc was significantly higher, and generation of tumor necrosis factor alpha and oxidative stress markers was significantly lower in the zinc-supplemented than in the placebo group.     

Facilitating factors and difficulties in the the implementation of sanitary surveillance of drugstores in Salvador, state of Bahia, Brazil

Drugstores are the health establishments where medications are dispensed, which is why sanitary surveillance is justified as a means of intervention. The health department uses various technologies to control risk in drugstores. In this study we used the theory of the process of work in health as a benchmark in order to describe and analyze the strengths and difficulties encountered in sanitary surveillance in drugstores in Salvador. Case study methodological strategy was adopted, the analytical categories being facilitating factors and difficulties inherent to technicians, drugstore, sanitary surveillance service and the social environment. Data were collected through direct observation techniques and semi-structured interviews, and the findings were assessed using content analysis. The body of information was processed and categorized using QSR N VIVO software. It was revealed that the nature of the facilitating factors and difficulties found in surveillance activities of drugstores indicate the need for urgent change within the scope of services and the sanitary culture in the country. It also stresses the possibilities of offering a quality service for the protection of health, in a setting conducive to the development of sanitary surveillance and the process of decentralization of these actions.     

The interface of public healthcare with the health of the oceans: proliferation of disease, socio-economic impacts and beneficial relationships

Over the past decades, human activities have had a heavy impact on the marine environment, causing alterations in ecological processes. The relationship between the health of the oceans, human activities and public healthcare is already generally accepted, though the mechanisms involved are still under scientific scrutiny. These relationships include a focus on climate change, toxic algal blooms, microbial and chemical contamination in marine waters and bioinvasion by exotic species. Moreover, there is the beneficial effect of the oceans on human health and wellbeing, such as natural products for the human diet, the development of biomedicine, or simply the satisfaction derived from human recreation, sports and other interactions of humans with oceans. The importance of appreciating the link between public healthcare and the health of the oceans is especially important due to the growing number of people living in coastal areas, mainly in tropical and subtropical regions. The backcloth to this is risk-related human activities that pose a danger to marine environmental health and the increase in the vulnerability of humans and biodiversity and socio-environmental iniquity.     

Evaluating the potential of an intervention aimed at promoting oral rehydration therapy (ORT) by educating pharmacy employees

Diarrhea is a major cause of morbidity and mortality in childhood, and Brazilians rely heavily on pharmacies for the resolution of this and other health problems. To promote the rational use of both pharmaceuticals and oral rehydration therapy (ORT), an intervention study was performed in pharmacies in Southwestern Brazil. Semi-structured interviews showed oral rehydration solution, or ORS (50%), antidiarrheals (39%), trimethoprim-sulfamethoxazole (27%), and yeast (22%) to be the most frequently suggested drugs, whereas questionnaire responses were ORS (75%), trimethoprim-sulfamethoxazole (25%), and yeast (25%), thus revealing that more than one methodology is needed if reliable data are to be obtained. An educational intervention was applied to 86.7% of pharmacies, but acquisition of knowledge on management of diarrhea did not prevent pharmacy workers from suggesting antidiarrheal drugs instead of ORS alone. In order to have pharmacy workers comply with official protocols for episodes of diarrhea, interventions should include regulatory measures on drugs that are contraindicated for children, and the role of pharmacies and pharmacists should be reviewed.     

Inter-observer reliability of digital vaginal examination using a four-grade scale in different patient positions

This study aims to compare digital vaginal examination with the patient in supine and standing position and to correlate the degree of pelvic organ prolapse (POP) with a prolapse quality of life (P-QOL) questionnaire. Two hundred and seven women with POP symptoms were digitally examined in supine and standing positions using a four-grade scale (none, minimal, moderate, and severe). P-QOL was used to assess the severity of prolapse symptoms. Cohen's kappa coefficient was used to calculate the inter-observer agreement and Spearman rank correlation test to assess the correlation between examination findings and P-QOL scores. Only vaginal examination findings in standing position had a good inter-observer reliability (kappa value 0.76-0.91). The severity of P-QOL scores only correlated with the examination findings in the standing position (P < 0.001). Digital examination of POP is unreliable if woman is supine but is reliable and correlates with symptoms and QOL impairment when the examination is performed with the patient standing.     

Inter-observer reliability of three different methods of measuring urethrovesical mobility

The aim of this study was to assess the inter-observer reliability of three different methods to evaluate urethral mobility in women: Q-tip test, ultrasonographic measurement and Sensor-Q™ test. From November 2006, consecutive women referred to our urogynecology units were submitted to one of the three procedures performed by two different urogynecologists, one blinded to the measurement obtained by the other. Sensor-Q™ test was performed using the specific equipment able to electronically assess urethral mobility. Data were analyzed using Pearson product moment correlation coefficient and Bland–Altman method comparison. Ninety patients were assessed. The Q-tip test, the Sensor-Q™ test and the ultrasonographic measurement were performed on 30 patients for each procedure. The correlation coefficient of the Q-tip test, the Sensor-Q™ test and the ultrasonographic measurement was 0.83, 0.92 and 0.43, respectively. The Sensor-Q™ and Q-tip test showed a higher inter-observer reliability for the evaluation of urethral mobility if compared to ultrasounds.
