Nourishing Communities and Consciousness at the Grassroots: An Interview with Carlos Ortez of Un Solo Sol Kitchen in Boyle Heights
Evidencias de la divergencia entre la visualización y el razonamiento geométrico
El presente estudio tiene por objetivo exponer las principales problemáticas que intervienen en el desarrollo del proceso de enseñanza-aprendizaje asociados a la geometría elemental. Apoyados por la literatura y a través de un cuestionario de tres preguntas; se pondrá en evidencia cómo estudiantes de 8° básico han ido construyendo sus conocimientos geométricos en base a aprendizajes memorísticos y disconexos; lo que presenta un gran obstáculo en el posterior proceso de desarrollo y apropiación de habilidades como la visualización, razonamiento y justificación. Con base en las respuestas obtenidas identificamos que la noción de ciertos elementos principales de la geometría están construidas por apreciaciones visuales más que por características y/o representaciones conceptuales
Undetectable Levels of CSF Amyloid-β Peptide in a Patient with 17β-Hydroxysteroid Dehydrogenase Deficiency
17β-hydroxysteroid dehydrogenase 10 (HSD10) deficiency is a rare X-linked inborn error of isoleucine catabolism. Although this protein has been genetically implicated in Alzheimer's disease pathogenesis, studies of amyloid-β peptide (Aβ) in patients with HSD10 deficiency have not been previously reported. We found, in a severely affected child with HSD10 deficiency, undetectable levels of Aβ in the cerebrospinal fluid, together with low expression of brain-derived neurotrophic factor, α-synuclein, and serotonin metabolites. Confirmation of these findings in other patients would help elucidating mechanisms of synaptic dysfunction in this disease, and highlight the role of Aβ in both early and late periods of life

Contraception and post abortion services: Qualitative analysis of users' perspectives and experiences following Zika epidemic in Honduras
Background: Zika virus (ZIKV) infection during pregnancy has severe consequences on the new-born. The World Health Organization declared the Zika outbreak to be a Public Health Emergency of International Concern (PHEIC) in 2016. Health facilities in the regions most affected by Zika lacked the capacity to respond to the increased demand for contraception. The objectives were to explore healthcare users' perceptions regarding contraception, Zika prevention during pregnancy and post-abortion care (PAC) services in the context of a Zika outbreak in Tegucigalpa, Honduras, and to follow these services over time. Methods: This study was part of a broader implementation research study. We used qualitative research consistent with grounded theory approach. Semi-structured interviews and focus groups were performed with women and their partners who used contraceptive services or received PAC services. Data were collected in two stages from December 2017 to July 2018. Themes explored included contraception, Zika and PAC services. Results: Participants had positive attitude towards the use of contraceptive methods and demanded more information on safety, efficacy and on side effects. Health care services were inconsistent in the provision of information on Zika and contraception services. ZIKV vector transmission was known but fewer participants were aware of risk of sexual transmission of Zika. Barriers to access healthcare services included contraceptive and PAC services included distance to healthcare facilities, disorganized admission process, long waiting times and out-of-pocket expenditure to purchase medicines. Furthermore, poor quality, mistreatment and abuse of women seeking PAC was prevalent. Some positive changes were noted over time, such as improvements in infrastructure including improved privacy and cleanliness, removal of fees, requisite to bring clean water to hospital. Conclusions: Our results highlight the challenges and areas for improvement in policy and practice related to contraceptive services and PAC in the context of ZIKV infection. Public policies to prevent epidemics should focus more on providing proper sanitation; removing barriers to access and use of effective contraception as human rights priority. Zika epidemic has highlighted weaknesses in health systems that obstruct access to and use of sexual and reproductive health services. The study results call for increased efforts to improve access, especially for women of low socio-economic status and intervene at different levels to eradicate discrimination and improve equity in the provision of health care. Qualitative methods can capture the community perspectives and can provide useful information to develop interventions to improve services.Fil: Belizan, Maria.
