Falling Through the Net? Gender and Social Protection in the Pacific

This paper examines the gender dimensions and implications of social protection in relation to rapid transformations in the globalizing economies in the Pacific region. The paper analyzes the dynamics of gender and social protection in three countries of the region -- Papua New Guinea, Tonga and Vanuatu -- and explores how best to approach social protection so as to promote gender equality rather than risk reinscribing prevailing gender inequalities. The paper emphasizes the need to move beyond bipolar divisions of customary and commodity economies or informal and formal economies to consider the everyday realities of making a living. Women will 'fall through the net' if social protection is unduly yoked to the public sphere of the state and the formal commodity economy in which women are marginalised. Women's own perceptions of their contemporary situation and their agency as both individuals and collectivities should be carefully heeded in finding creative solutions for gender equality in social protection for sustainable Pacific futures. The paper concludes by suggestion that efforts to ensure women's social protection in the Pacific need to be alert to the risks that women might 'fall through the net.'

Aldosterone upregulates transient receptor potential melastatin 7 (TRPM7)

Transient receptor potential melastatin 7 (TRPM7) is a ubiquitously expressed Mg2+-permeable ion channel fused to a C-terminal α-kinase domain. Recently, aldosterone was shown to increase intracellular Mg2+ levels and alter inflammatory signaling in TRPM7-expressing HEK293 cells. This study was undertaken to assess whether these effects were related to an aldosterone-mediated increase of TRPM7 current and/or plasma membrane localization. Using HEK293 cells stably expressing WT-TRPM7, we found that 18-h application of aldosterone significantly increased TRPM7 current and TRPM7 plasma membrane protein expression by 48% and 34%, respectively. The aldosterone-mediated increase of TRPM7 current was inhibited by eplerenone, a mineralocorticoid receptor (MR) blocker, and GSK-650394, an inhibitor of the serum- and glucocorticoid-regulated kinase 1 (SGK1). SGK1 blockade also prevented the aldosterone-induced increase of TRPM7 plasma membrane protein. It was further determined that K1648R-TRPM7, the phosphotransferase-inactive TRPM7 mutant, was unresponsive to aldosterone. Therefore, chronic aldosterone treatment increases the plasma membrane expression of TRPM7, which is associated with an increase of TRPM7 current. This process occurs via an MR-dependent, genomic signaling cascade involving SGK1 and a functioning TRPM7 α-kinase domain. We suggest that this mechanism may be of general relevance when interpreting the effects of aldosterone because the MR receptor is found in multiple tissues, and TRPM7 and SGK1 are ubiquitously expressed

To use or not to use a condom: A prospective cohort study comparing contraceptive practices among HIV-infected and HIV-negative youth in Uganda

<p>Abstract</p> <p>Background</p> <p>Unwanted pregnancy and HIV infection are issues of significant concern to young people. Limited data exists on contraceptive decision-making and practices among HIV-infected and HIV-negative young people in low resource settings with generalized HIV epidemics.</p> <p>Methods</p> <p>From July 2007 until April 2009, we recruited, and followed up over a one year period, a cohort of 501 HIV-negative and 276 HIV-infected young women and men aged 15-24 years residing in Kampala and Wakiso districts. We compared contraceptive use among HIV-infected and HIV-negative young people and assessed factors associated with contraceptive decision-making and use, using multivariate logistic regression modelling to estimate odds ratios (OR) and 95% confidence intervals (CI).</p> <p>Results</p> <p>Contraceptive use among sexually active HIV-infected young people was 34% while it was 59% among the HIV-negative group. The condom was the most frequently used method of contraception. Only 24% of the HIV-infected used condoms consistently compared to 38% among the negative group OR 0.56 (95% CI 0.38, 0.82). HIV-infected young people were more likely to discuss safe sex behaviour with health workers OR 1.70 (95% CI 1.13, 2.57), though its effect on fertility decision-making was not significant. Throughout the year's follow-up, only 24% among the HIV-negative and 18% among the HIV-infected continued to use contraception while 12% and 28% among the HIV-negative and infected respectively did not use contraception at all. At multivariate analysis, the HIV-infected young people were less likely to maintain contraceptive use. Other factors independently associated with sustained contraceptive use were age of the respondent, marital status and being a male. Conversely, HIV-infected young people were less likely to initiate use of contraception. Being married or in a relationship was associated with higher odds of initiating contraceptive use.</p> <p>Conclusion</p> <p>Compared to the HIV-negative group, sexually active HIV-infected young people are less likely to use contraception and condoms. Initiating or sustaining contraceptive use was also significantly less among the HIV-infected group. Strengthening family planning services and developing new innovative ideas to re-market condom use are needed. Policy and guidelines that empower health workers to help young people (especially the HIV infected) express their sexuality and reproduction should urgently be developed.</p

My partner wants a child: A cross-sectional study of the determinants of the desire for children among mutually disclosed sero-discordant couples receiving care in Uganda

<p>Abstract</p> <p>Background</p> <p>The percentages of couples in HIV sero-discordant relationships range from 5 to 31% in the various countries of Africa. Given the importance of procreation and the lack of assisted reproduction to avoid partner transmission, members of these couples are faced with a serious dilemma even after the challenge of disclosing their HIV status to their spouses. Identifying the determinants of the decision to have children among sero-discordant couples will help in setting reproductive intervention priorities in resource-poor countries.</p> <p>Methods</p> <p>We conducted a survey among 114 mutually disclosed sero-discordant couples (228 individuals) receiving HIV care at four centres in Greater Kampala, between June and December 2007. The data we collected was classified according to whether the man or the woman was HIV-positive. We carried out multivariate logistic regression modelling to determine factors (age, gender, and the influences of relatives and of health workers, ART knowledge, and disclosure) that are independently associated with a desire for children.</p> <p>Results</p> <p>The majority, 59%, of the participants, desired to have children. The belief that their partner wanted children was a major determinant of the desire to have children, irrespective of the HIV sero-status (adjusted odds ratio 24.0 (95% CI 9.15, 105.4)). Among couples in which the woman was HIV-positive, young age and relatives' expectations for children were significantly associated with increased fertility desire, while among couples in which the man was positive; knowledge of ART effectiveness was associated with increased fertility desire. Availability of information on contraception was associated with decreased fertility desire.</p> <p>Conclusions</p> <p>The gender of the positive partner affects the factors associated with a desire for children. Interventions targeting sero-discordant couples should explore contraceptive choices, the cultural importance of children, and partner communication.</p

Aptamer-based Field-Effect Biosensor for Tenofovir Detection

During medical treatment it is critical to maintain the circulatory concentration of drugs within their therapeutic range. A novel biosensor is presented in this work to address the lack of a reliable point-of-care drug monitoring system in the market. The biosensor incorporates high selectivity and sensitivity by integrating aptamers as the recognition element and field-effect transistors as the signal transducer. The drug tenofovir was used as a model small molecule. The biointerface of the sensor is a binary self-assembled monolayer of specific thiolated aptamer and 6-mercapto-1-hexanol (MCH), whose ratio was optimized by electrochemical impedance spectroscopy measurements to enhance the sensitivity towards the specific target. Surface plasmon resonance, performed under different buffer conditions, shows optimum specific and little non-specific binding in phosphate buffered saline. The dose-response behavior of the field-effect biosensor presents a linear range between 1 nM and 100 nM of tenofovir and a limit of detection of 1.2 nM. Two non-specific drugs and one non-specific aptamer, tested as stringent control candidates, caused negligible responses. The applications were successfully extended to the detection of the drug in human serum. As demonstrated by impedance measurements, the aptamer-based sensors can be used for real-time drug monitoring

Who opposes the EU? continuity and change in party Euroscepticism between 2014 and 2019

A new round of data from the Chapel Hill Expert Survey, covering 2019, is due to be released. The survey, which estimates the positions of political parties on a variety of ideological and policy issues, offers an invaluable tool for assessing political competition in Europe. Ryan Bakker, Liesbet Hooghe, Seth Jolly, Gary Marks, Jonathan Polk, Jan Rovny, Marco Steenbergen, and Milada Anna Vachudova draw on the latest data to examine where European political parties now stand on European integration, and how their positions have changed since the last full survey was conducted in 2014

Seroprevalence of Zika virus in wild African green monkeys and baboons

ABSTRACT Zika virus (ZIKV) has recently spread through the Americas and has been associated with a range of health effects, including birth defects in children born to women infected during pregnancy. Although the natural reservoir of ZIKV remains poorly defined, the virus was first identified in a captive “sentinel” macaque monkey in Africa in 1947. However, the virus has not been reported in humans or nonhuman primates (NHPs) in Africa outside Gabon in over a decade. Here, we examine ZIKV infection in 239 wild baboons and African green monkeys from South Africa, the Gambia, Tanzania, and Zambia using combinations of unbiased deep sequencing, quantitative reverse transcription-PCR (qRT-PCR), and an antibody capture assay that we optimized using serum collected from captive macaque monkeys exposed to ZIKV, dengue virus, and yellow fever virus. While we did not find evidence of active ZIKV infection in wild NHPs in Africa, we found variable ZIKV seropositivity of up to 16% in some of the NHP populations sampled. We anticipate that these results and the methodology described within will help in continued efforts to determine the prevalence, natural reservoir, and transmission dynamics of ZIKV in Africa and elsewhere. IMPORTANCE Zika virus (ZIKV) is a mosquito-borne virus originally discovered in a captive monkey living in the Zika Forest of Uganda, Africa, in 1947. Recently, an outbreak in South America has shown that ZIKV infection can cause myriad health effects, including birth defects in the children of women infected during pregnancy. Here, we sought to investigate ZIKV infection in wild African primates to better understand its emergence and spread, looking for evidence of active or prior infection. Our results suggest that up to 16% of some populations of nonhuman primate were, at some point, exposed to ZIKV. We anticipate that this study will be useful for future studies that examine the spread of infections from wild animals to humans in general and those studying ZIKV in primates in particular.
