Addressing SRGBV in Ethiopia: A scoping study of policy and practice to reduce gender-based violence in and around schools
School-related gender-based violence (SRGBV) describes physical, sexual and psychological acts of violence in and around schools, underpinned by unequal access to resources and power, and inequitable norms and stereotypes. While there is increasing recognition of SRGBV as a major issue globally, rigorous reviews of literature have concluded that evidence about effective ways to address it is lacking. The End Gender Violence in Schools (EGVS) initiative, led by UNICEF with support from the Global Partnership for Education (GPE) and UNGEI, aims to build evidence to better understand, inform and strengthen the process of policy enactment on SRGBV in Ethiopia, Zambia, Togo and Cote d’Ivoire. Findings from the initiative in these four countries will contribute to global debates on how to address SRGBV. This summary presents draft findings from a scoping study of policy, practice and evidence on SRGBV in Ethiopia, which was carried out in 2016. The main objective of the study was to analyse responses to gender-based violence in and around schools in Ethiopia, in order to inform future planning of policy and practice initiatives. The study was a collaboration between the Government of Ethiopia, UNICEF, and the UCL Institute of Education. Several methods for data collection were employed: 1) Two interactive workshops led by the Ministry of Education and facilitated by UNICEF and the UCL Institute of Education (March 2016; December 2016); 2) Literature review and documentary analysis of legislative and policy texts, research reports and datasets, and documents describing programmes or interventions addressing SRGBV in Ethiopia; 3) 23 in-depth interviews with governmental and non-governmental experts. The research questions addressed 1) what we know about SRGBV in Ethiopia, 2) what policies, laws and programmes exist and how well they are enacted, and 3) the availability and quality of evidence on SRGBV
Meta-Analysis of Prevalence and Risk Factors for Cognitive Decline and Improvement After Transcatheter Aortic Valve Implantation
Changes to cognition, both decline and improvement, are commonly reported after transcatheter aortic valve implantation (TAVI). However, previous systematic reviews and meta-analyses have missed these subgroups by assessing whole-group-averages for cognitive outcomes. We sought to pool estimates to identify the prevalence of cognitive decline and improvement after TAVI, as well as associated factors for these outcomes. A systematic review identified 15 articles appropriate for meta-analysis. When robust cognitive change definitions were employed, the pooled prevalence of incident cognitive impairment up to 1-, 1 to 6-, and ≥6-months post-TAVI was 7%, 14%, and 12%, respectively. For cognitive improvement, the prevalence from 1 to 6 months and ≥6 months after TAVI was estimated to be 19% and 11%, respectively. Two factors were associated with these cognitive outcomes: (1) using a cerebral embolic protection device was associated with decreased prevalence of cognitive decline up to 1-week post-TAVI; (2) baseline cognitive impairment had a large association with post-TAVI cognitive improvement. In conclusion, cognitive decline and cognitive improvement are experienced by approximately 7% to 19% of patients after TAVI, respectively. Those with the lowest cognitive performance pre-TAVI appear to have the most to gain in terms of cognitive improvement post-TAVI. Identifying further predictive factors for cognitive decline and improvement post-TAVI will facilitate a personalized-medicine approach for cognitive care and prognosis
Addressing School Related Gender Based Violence in Zambia: A Scoping Study
This report presents findings from a scoping study of policy, practice and evidence on school-related
gender-based violence (SRGBV) in Zambia, which was carried out in 2016. The main objective of the
study was to analyse responses to gender-based violence in and around schools in Zambia, in order to
inform future planning of policy and practice initiatives. The study was a collaboration between the
government of Zambia, UNICEF, and researchers at the UCL Institute of Education working alongside
consultant, Romana Maumbu. Its core elements consist of: analysis of legislation and policy; analysis
of programming on SRGBV; mapping of stakeholders working on SRGBV; and the identification and
evaluation of research and data sets. The findings presented here will be used to guide decision
making for phase two of the initiative which will take place during 2017, as well as longer term
planning and action on SRGBV in Zambia. The findings will provide the basis for reflection and the
development of the action plan for the next phase of the EGVS initiative
Ocular sarcoidosis and tuberculous lymphadenopathy: coincidence or real association
Tuberculosis and sarcoidosis share similarity in histopathologic findings and clinically occur in association with each other occasionally. Tuberculosis should always be ruled out before the diagnosis of sarcoidosis. But, the diagnosis is often complicated, especially in extrapulmonary cases. Here we present a case of bilateral vitreous hemorrhage with uveitis. Ocular sarcoidosis was initially diagnosed based on the characteristic ocular findings, negative results on chest radiography, tuberculosis culture, and polymerase chain reaction of aqueous, as well as simultaneous presence of panda and lambda sign on gallium-67 scans. The ocular condition improved after pars plana vitrectomy and systemic steroid therapy. However, TB lymphadenopathy but no recurrent ocular inflammation was found 6 years later. The patient received anti-TB treatment for 6 months thereafter. The eyes remained silent except cataract progression and glaucoma under two medications during this period. In conclusion, TB could occur coincidently or in association with sarcoidosis, continued follow-up is important for patients with ocular sarcoidosis
Ensuring transparency and minimization of methodologic bias in preclinical pain research: PPRECISE considerations
ERCC1 expression and RAD51B activity correlate with cell cycle response to platinum drug treatment not DNA repair
Background: The H69CIS200 and H69OX400 cell lines are novel models of low-level platinum-drug resistance. Resistance was not associated with increased cellular glutathione or decreased accumulation of platinum, rather the resistant cell lines have a cell cycle alteration allowing them to rapidly proliferate post drug treatment. Results: A decrease in ERCC1 protein expression and an increase in RAD51B foci activity was observed in association with the platinum induced cell cycle arrest but these changes did not correlate with resistance or altered DNA repair capacity. The H69 cells and resistant cell lines have a p53 mutation and consequently decrease expression of p21 in response to platinum drug treatment, promoting progression of the cell cycle instead of increasing p21 to maintain the arrest.
Conclusion: Decreased ERCC1 protein and increased RAD51B foci may in part be mediating the maintenance of the cell cycle arrest in the sensitive cells. Resistance in the H69CIS200 and H69OX400 cells may therefore involve the regulation of ERCC1 and RAD51B independent of their roles in DNA repair. The novel mechanism of platinum resistance in the H69CIS200 and H69OX400 cells demonstrates the multifactorial nature of platinum resistance which can occur independently of alterations in DNA repair capacity and changes in ERCC1
Separation of Anti-Proliferation and Anti-Apoptotic Functions of Retinoblastoma Protein through Targeted Mutations of Its A/B Domain
BACKGROUND: The human retinoblastoma susceptibility gene encodes a nuclear phosphoprotein RB, which is a negative regulator of cell proliferation. The growth suppression function of RB requires an evolutionarily conserved A/B domain that contains two distinct peptide-binding pockets. At the A/B interface is a binding site for the C-terminal trans-activation domain of E2F. Within the B-domain is a binding site for proteins containing the LxCxE peptide motif. METHODOLOGY/PRINCIPLE FINDINGS: Based on the crystal structure of the A/B domain, we have constructed an RB-K530A/N757F (KN) mutant to disrupt the E2F- and LxCxE-binding pockets. The RB-K530A (K) mutant is sufficient to inactivate the E2F-binding pocket, whereas the RB-N757F (N) mutant is sufficient to inactivate the LxCxE-binding pocket. Each single mutant inhibits cell proliferation, but the RB-KN double mutant is defective in growth suppression. Nevertheless, the RB-KN mutant is capable of reducing etoposide-induced apoptosis. CONCLUSION/SIGNIFICANCE: Previous studies have established that RB-dependent G1-arrest can confer resistance to DNA damage-induced apoptosis. Results from this study demonstrate that RB can also inhibit apoptosis independent of growth suppression
Integrated genomics and proteomics define huntingtin CAG length-dependent networks in mice.
To gain insight into how mutant huntingtin (mHtt) CAG repeat length modifies Huntington's disease (HD) pathogenesis, we profiled mRNA in over 600 brain and peripheral tissue samples from HD knock-in mice with increasing CAG repeat lengths. We found repeat length-dependent transcriptional signatures to be prominent in the striatum, less so in cortex, and minimal in the liver. Coexpression network analyses revealed 13 striatal and 5 cortical modules that correlated highly with CAG length and age, and that were preserved in HD models and sometimes in patients. Top striatal modules implicated mHtt CAG length and age in graded impairment in the expression of identity genes for striatal medium spiny neurons and in dysregulation of cyclic AMP signaling, cell death and protocadherin genes. We used proteomics to confirm 790 genes and 5 striatal modules with CAG length-dependent dysregulation at the protein level, and validated 22 striatal module genes as modifiers of mHtt toxicities in vivo
