Project description:Determining farmers' real demand for crop insurance is difficult, especially in developing countries, where there is a lack of formal financial sector integration and a high reliance on informal risk mitigation options. We provide some new estimates of farmers' willingness-to-pay for insurance in the context of a large-scale subsidised programme in India. We conducted a discrete choice experiment with agricultural households across four states in India, enabling us to estimate preferences for specific insurance policy attributes such as coverage period, method of loss assessment, timing of indemnity payments and the cost of insurance. Our results suggest that farmers do value crop insurance under certain conditions and some are willing to pay a premium for such coverage in excess of the subsidised rates they are currently required to pay under this programme. In particular, farmers value the assurances that they will receive timely payouts when they incur losses, and may not have a strong preference for the method with which losses are assessed. On the other hand, farmers are quite sensitive to coverage periods. Our baseline assessment shows that when optimised to farmer requirements, there can be a sizeable demand for crop insurance by developing country farmers.

Project description:At the centre of the multi-dimensional impact of the COVID-19 pandemic, the shortage of medical supplies in countries with weaker healthcare systems significantly reduced the effectiveness of national and international public health interventions. Using a database of test-kit trade flows and barriers, we estimate the price responsiveness of test-kit demand in a global sample of countries. These estimates allow us to investigate the degree to which import tariffs by leading producers could result in a disruption in global supply chains, price increases, and welfare loss. Simulation experiments indicate that the combination of rising demand for test kits and import dependence magnifies the impact of trade barriers on consumer welfare and this impact is more profound for developing countries.

Project description:The present study describes an immunocytochemistry (ICC) assay with self-raised hyperimmune sera and a Baby Hamster Kidney-21 (BHK-21) cell line infected with Porcine Sapelovirus (PSV). Sapelovivus/IVRI/SPF-c-6/2015 strain Indian PSV was isolated from the porcine IBRS-2 cell line and investigated for growth on non-porcine cell lines. After two passages, PSV was successfully grown in BHK-21 and produced the same cytopathic effects as in IBRS-2 such as shrinking of cytoplasm, rounding of cells and detachment of cells from the surface of flask within 24 h. For raising of hyperimmune sera, PSV was grown in IBRS-2 cell line up to the required volume and purified by ultracentrifugation. With self-raised hyperimmune sera in laboratory rats, ICC was performed in BHK-21 cells infected with PSV. Positive signals consisted of large granular aggregates of virus in the cytoplasm near the nucleus, suggesting that PSV can infect cell lines other than those of porcine origin.

Project description:Is it in the interest of a developing country to promote strong local linkages for domestic industries or to participate in global value chains (GVCs) wherein linkages are globally dispersed? This paper informs this debate by empirically analyzing which one of these strategies would result in higher levels of domestic value added (DVA) and employment in India. Using a unique panel data on DVA and jobs tied to Indian exports from 112 sectors for the period 1999–2000 to 2012–2013, we show that greater backward GVC participation—use of imported inputs to produce for exports—leads to higher absolute levels of gross exports, DVA and employment. This result implies that labor abundant countries can reap dividends by adopting policies aimed at strengthening their backward participation in GVCs. Our findings are robust to various estimation techniques and instrumental variable approaches to address potential endogeneity concerns.

Project description:BackgroundThere is scanty or inconclusive evidence on which cervical cancer screening tool is effective and suitable for human immunodeficiency virus (HIV)-seropositive women. The aim of this review was to assess, synthesise and document published evidence relating to the available cervical cancer screening modalities for HIV-seropositive women in developing countries. This paper did not review the issue of human papillomavirus (HPV) prophylactic vaccine on HIV-seropositive women.MethodsFive electronic databases were systematically searched from inception to January 2018 for relevant published original research examining cervical cancer prevention modalities for HPV infection, abnormal cytology and direct visualisation of the cervix amongst HIV-seropositive women in developing countries. Extra studies were identified through reference list and citation tracking.ResultsDue to methodological and clinical heterogeneity, a narrative synthesis was presented. Of the 2559 articles, 149 underwent full-text screening and 25 were included in the review. Included studies were of moderate quality, and no exclusions were made based on quality or bias. There is no standard cervical cancer screening test or programme for HIV-seropositive women and countries screening according to available resources and expertise. The screening methods used for HIV-seropositive women are the same for HIV-negative women, with varying clinical performance and accuracy. The main cervical cancer screening methods described for HIV-seropositive women are HPV deoxyribonucleic acid/messenger RNA (DNA/mRNA) testing (n?=?16, 64.0%), visual inspection with acetic acid (VIA) (n?=?13, 52.0%) and Pap smear (n?=?11, 44.0%). HPV testing has a better accuracy/efficiency than other methods with a sensitivity of 80.0-97.0% and specificity of 51.0-78.0%. Sequential screening using VIA or visual inspection with Lugol's iodine (VILI) and HPV testing has shown better clinical performance in screening HIV-seropositive women.ConclusionAlthough cervical cancer screening exists in almost all developing countries, what is missing is both opportunistic and systematic organised population-based screenings. Cervical cancer screening programmes need to be integrated into already existing HIV services to enable early detection and treatment. There is a need to offer opportunistic and coordinated screening programmes that are provider-initiated to promote early identification of cervical precancerous lesions.Systematic review registrationPROSPERO CRD42018095702.

Project description:BackgroundOver 85% of cervical cancer cases and deaths occur in developing countries. HIV-seropositive women are more likely to develop precancerous lesions that lead to cervical cancer than HIV-negative women. However, the literature on cervical cancer prevention in seropositive women in developing countries has not been reviewed. The aim of this study is to systematically review cervical cancer prevention modalities available for HIV-seropositive women in developing countries.Methods/designThis protocol was developed by following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) statement, and the systematic review will be reported in accordance with the PRISMA guidelines. Embase, MEDLINE, PubMed, CINAHL and Cochrane Library will be searched from inception up to date of final search, and additional studies will be located through citation and reference list tracking. Eligible studies will be randomised controlled trials, prospective and retrospective cohort studies, case-control and cross-sectional studies carried out in developing countries. Studies will be included if they are published in English and examine cervical cancer prevention modalities in HIV-seropositive women. Results will be summarised in tables and, where appropriate, combined using meta-analysis.DiscussionThis review will address the gap in evidence by systematically reviewing the published literature on the different prevention modalities being used to prevent cervical cancer in HIV-seropositive women in developing countries. The findings may be used to inform evidence-based guidelines for prevention of cervical cancer in seropositive women as well as future research.Systematic review registrationPROSPERO CRD42017054678 .

Project description:BACKGROUND:Commercial surrogacy is a highly controversial issue that leads to heated debates in the feminist literature, especially when surrogacy takes place in developing countries and when it is performed by local women for wealthy international individuals. The objective of this article is to confront common assumptions with the narratives and experiences described by Indian surrogates themselves. METHODS:This qualitative study included 33 surrogates interviewed in India (Mumbai, Chennai and New Delhi) who were at different stages of the surrogacy process. They were recruited through five clinics and agencies. This 2-year field study was conducted before the 2018 surrogacy law. RESULTS:Surrogates met the criteria fixed by the national guidelines in terms of age and marital and family situation. The commitment to surrogacy had generally been decided with the husband. Its aim was above all to improve the socioeconomic condition of the family. Women described surrogacy as offering better conditions than their previous paid activity. They had clear views on the child and their work. However, they declared that they faced difficulties and social condemnation as surrogacy is associated with extra-marital relationships. They also described a medical process in which they had no autonomy although they did not express complaints. Overall, surrogates did not portray themselves as vulnerable women and victims, but rather as mothers and spouses taking control of their destiny. CONCLUSIONS:The reality of surrogacy in India embraces antagonistic features that we analyze in this paper as "paradoxes". First, while women have become surrogates in response to gender constraints as mothers and wives, yet in so doing they have gone against gender norms. Secondly, while surrogacy was socially perceived as dirty work undertaken in order to survive, surrogates used surrogacy as a means to upward mobility for themselves and their children. Finally, while surrogacy was organized to counteract accusations of exploitation, surrogates were under constant domination by the medical system and had no decision-making power in the surrogacy process. This echoes their daily life as women. Although the Indian legal framework has changed, surrogacy still challenges gender norms, particularly in other developing countries where the practice is emerging.

Project description:BACKGROUND:Cervical cancer has become a major public health challenge in developing countries with a reported age-standardised incidence rate of about 17.9/100,000/year and lifetime risks approaching 1 in 20 in some settings. Evidence indicates that HIV-seropositive women are 2 to 12 times more likely to develop precancerous lesions that lead to cervical cancer than HIV-negative women. There is a lack of rigorous evidence on which treatment methods are being utilised for HIV-positive women, and this review aims to synthesise available evidence on treatment modalities for both cervical neoplasia and cervical cancer in HIV-seropositive women in developing countries. METHODS:A systematic review guided by a published protocol was conducted. Online databases including MEDLINE/PubMed, Embase, CINAHL and Emerald (via EBSCOhost), PsycINFO, Cochrane Library, and health databases, which cover developing countries (3ie Systematic Reviews, WHO library and databases, World Bank website), were searched for published articles. Additional articles were found through citation, reference list tracking, and grey literature. Study design, treatment category, geographic country/region, and key outcomes for each included article were documented and summarised. RESULTS:Thirteen research articles from sub-Saharan Africa, Asia, and South America were included. Eight (61.5%) articles focused on the treatment of cervical cancer with the remaining five (38.5%) assessed cervical neoplasia treatment. The available cervical cancer treatments, radiotherapy, chemotherapy, chemoradiation, and surgery are effective for HIV-seropositive patients, and these are the same treatments for HIV-negative patients. Both cryotherapy and LEEP are effective in reducing CIN2+ among HIV-seropositive women, and a choice between the treatments might be based on available resources and expertise. Radiation, chemotherapy, concurrent treatment using radiotherapy and chemotherapy, and surgery have shown the possibility of effectiveness among HIV-seropositive women. Cervical cancer stage, immunosuppressive level including those on HAART, and multisystem toxicities due to treatment are associated with treatment completion, prognostic, and survival outcomes. CONCLUSIONS:Treatment of cervical cancer is based on the stage of cancer, and poor outcomes in most developing countries might be due to a lack of optimal treatment regimen. Those infected with HIV were younger and had advanced cervical cancer as compared to those who were HIV-negative. Facilitation and putting HIV-infected people on life-long ART is of importance and has been found to have a positive impact on cervical cancer treatment response. Research on precancerous lesions and cervical cancer management of HIV-seropositive patients focusing on the quality of life of those treated; the effectiveness of the treatment method considering CD4+ count and ART is required.

Project description:Cervical cancer has become the most common cancer affecting women in Africa. Significantly, 85% of these annual deaths occur in the developing world, with the majority being middle-aged women. Research has shown that in sub-Saharan Africa, cervical cancer trends are on the rise in the past two decades because of HIV and this has resulted in an increase in cervical cancer cases among young women. However, little or no information exists that has shown that any of the available treatment methods are more effective than others when it comes to treating cervical cancer in HIV-seropositive women. The aim of this protocol is to offer a plan on how to systematically review cervical cancer treatment methods available for HIV-seropositive women in developing countries.The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) statement was used to develop the protocol for the systematic review which will be reported in accordance with the PRISMA guidelines. A number of databases, Embase, MEDLINE, PubMed, CINAHL and Cochrane Library, will be searched for relevant studies, and citation and reference list tracking will be used to search for additional studies. Prospective and retrospective cohort studies, case-control, randomised controlled trials and cross-sectional studies that were carried out in and for the developing world will be eligible for inclusion. Peer-reviewed studies and grey literature examining cervical cancer treatment modalities in HIV-seropositive women will be included. Descriptive statistics and tables will be used to summarise results, and meta-analysis will be used where appropriate.The review findings will provide the current picture of the existing treatment methods being used to treat cervical cancer in HIV-seropositive women in developing countries. The findings might be used for the establishment of evidence-based guidelines for treatment of cervical cancer in seropositive women as well as prompt policy-makers and governments to decide and support future research in a way to find a lasting solution.PROSPERO CRD42017054676 https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=54676.
