Compliance of balanced housing policy in the Philippines: the case of Davao City

The Philippines have quintessentially suffered setbacks in providing the housing needs for the underprivileged and homeless urban poor. The reformist policy through the balanced housing principle of the Urban Development and Housing Act (UDHA) has augured well as a strategy to cope with the socialized housing requirement brought by rapid urbanization. This paper assesses the compliance of balanced housing policy by the State and the private housing developers in the city of Davao. The study explores the mechanisms used by government to ensure compliance and the modalities availed by housign developers, and provide policy recommendation for the efficient implementation and compliance with the policy. Although there was compliance from the private sector, the policy was tweaked which resulting in considerable loss of socialized housing units in Davao City due to ambiguous application of balanced housing policy. Equally significant difficulty for an efficient implementation is the weak administrative mechanisms, causing a failure in the compliance and monitoring aspects, coupled with lack of understanding and the determination to implement the balanced housing policy. Thus, the government of Davao city needs to approach the growing urban homelessness with resolve and urgency thereby accelerating the production of socialized housing through the balanced housing policy

Copyright: Copyright 2020 Elsevier B.V., All rights reserved.Penicillium verrucosum survives in soil and on cereal debris. It colonises grain during harvesting, drying and storage. There is no information on the relative tolerance of P. verrucosum to solute and matric stress in terms of colonisation, or on the biosynthetic toxin gene clusters or ochratoxin A (OTA) production. The objectives were to examine the effect of ionic and non-ionic solute and matric potential stress on (a) growth, (b) expression of two toxin biosynthetic genes otapksPV and otanrpsPV, and (c) OTA production by a strain of P. verrucosum. Optimum growth and OTA production were at-7.0 MPa (= 0.95 water activity, aw) and-1.4 MPa (= 0.99 aw), respectively, regardless of whether solute (Ψs) or matric (Ψm) stress was imposed. P. verrucosum was more sensitive to ionic solute stress (NaCl) with no growth at-19.6 MPa (=0.86 aw) while growth still occurred in the non-ionic solute (glycerol) and matric stress treatments. Relative gene expression of the biosynthetic genes using PCR (RT-qPCR) showed that the otapksPV gene was expressed over a wide range of ionic/non-ionic solute stress conditions (-1.4 to-14.0 MPa; = 0.99-0.90 aw). The highest expression was in the non-ionic Ψs stress treatments at-7.0 MPa (= 0.95 aw). However, the otanrpsPV gene was significantly up regulated under Ψm stress, especially with freely available water (-1.4 MPa = 0.99 aw). OTA production was significantly decreased as Ψs or Ψm stress were imposed. Limited OTA production occurred in the driest treatments under Ψs and Ψm stress respectively. The impact of these two types of stresses on the growth of P. verrucosum was quite different from that for OTA production. The results are discussed in the context of the life cycle and ecological characteristics of this species in contaminating cereals with OTA in the post-harvest phase of the cereal chain.Peer reviewedFinal Accepted Versio

Resilience of biocontrol for aflatoxin minimisation strategies: climate change abiotic factors may affect control in non-GM and GM-maize cultivars

here has been significant interest in the development of formulations of non-toxigenic strains of Aspergillus flavus for control of toxigenic strains to reduce the aflatoxin B1 (AFB1) contamination of maize. In the future, climate change (CC) abiotic conditions of temperature (+2–4°C), CO2 (existing levels of 400 vs. 800–1,200 ppb), and drought stress will impact on the agronomy and control of pests and diseases. This study has examined (1) the effect of two-way interacting factors of water activity × temperature on colonization and AFB1 contamination of maize cobs of different ripening ages; (2) the effect of non-toxigenic strains of A. flavus (50:50 inoculum ratio) on relative control of toxigenic A. flavus and AFB1 contamination of ripening cobs; (3) post-harvest control of AFB1 by non-toxigenic strains of A. flavus in non-GM and isogenic GM maize cultivars using the same inoculum ratio; and (4) the impact of three-way interacting CC factors on relative control of AFB1 in maize cobs pre-harvest and in stored non-GM/GM cultivars. Pre-harvest colonization and AFB1 production by a toxigenic A. flavus strain was conserved at 37°C when compared with 30°C, at the three ripening stages of cob development examined:milk ripe (R3), dough (R4), and dent (R5). However, pre-harvest biocontrol with a non-toxigenic strain was only effective at the R3 and R4 stages and not at the R5 stage. This was supported by relative expression of the aflR regulatory biosynthetic gene in the different treatments. When exposed to three-way interacting CC factors for control of AFB1 pre-harvest, the non-toxigenic A. flavus strain was effective at R3 and £4 stages but not at the R5 stage. Post-harvest storage of non-GM and GM cultivars showed that control was achievable at 30°C, with slightly better control in GM-cultivars in terms of the overall inhibition of AFB1 production. However, in stored maize, the non-toxigenic strains of A. flavus had conserved biocontrol of AFB1 contamination, especially in the GM-maize cultivars under three-way interacting CC conditions (37°C × 1,000 ppm CO2 and drought stress). This was supported by the relative expression of the aflR gene in these treatments. This study suggests that the choice of the biocontrol strains, for pre- or post-harvest control, needs to take into account their resilience in CC-related abiotic conditions to ensure that control of AFB1 contamination can be conserved

El presente trabajo se enfoca en el fenómeno social que flagela no solo nuestra sociedad, sino en casi todos los países del mundo pues la violencia contra la mujer e integrantes del grupo familiar va en un aumento alarmante por distintos motivos, mismos que pasamos a exponer con la presente investigación titulándose así Causas que provocan la ineficacia de la Ley 30364 en los procesos de violencia contra la mujer e integrantes del grupo familiar. A través de este estudio, se identificó que son distintas las causas que entorpecen el objetivo de prevenir, erradicar y sancionar toda forma de violencia de la Ley 30364. En el presente trabajo de enfoque cualitativo se ha empleado el análisis documental y se aplicó la técnica de recolección de datos como la entrevista y la revisión documental. En ese marco, se concluyó que las causas que provocan la ineficacia de la Ley 30364 en procesos de violencia contra los sujetos de protección regulados en dicha norma son la sobrecarga procesal, incumplimiento de las medidas de protección por parte del agresor y las medidas de protección que no son exactas para cada caso en concreto toda vez que se verifica que las víctimas mortales incrementan día a día

A comparative analysis of costs of single and dual rapid HIV and syphilis diagnostics: results from a randomised controlled trial in Colombia.

BACKGROUND: HIV and congenital syphilis are major public health burdens contributing to substantial perinatal morbidity and mortality globally. Although studies have reported on the costs and cost-effectiveness of rapid diagnostic tests (RDTs) for syphilis screening within antenatal care in a number of resource-constrained settings, empirical evidence on country-specific cost and estimates of single RDTs compared with dual RDTs for HIV and syphilis are limited. METHODS: A cluster randomised controlled study design was used to compare the incremental costs of two testing algorithms: (1) single RDTs for HIV and syphilis and (2) dual RDTs for HIV and syphilis, in 12 health facilities in Bogota and Cali, Colombia. The costs of single HIV and syphilis RDTs and dual HIV and syphilis RDTs were collected from each of the health facilities. The economic costs per woman tested for HIV and syphilis and costs per woman treated for syphilis defined as the total costs required to test and treat one woman for syphilis were estimated. RESULTS: A total of 2214 women were tested in the study facilities. Cost per pregnant woman tested and cost per woman treated for syphilis were US$10.26 and US$607.99, respectively in the single RDT arm. For the dual RDTs, the cost per pregnant woman tested for HIV and syphilis and cost per woman treated for syphilis were US$15.89 and US$1859.26, respectively. Overall costs per woman tested for HIV and syphilis and cost per woman treated for syphilis were lower in Cali compared with Bogota across both intervention arms. Staff costs accounted for the largest proportion of costs while treatment costs comprised <1% of the preventive programme. CONCLUSIONS: Findings show lower average costs for single RDTs compared with dual RDTs with costs sensitive to personnel costs and the scale of output at the health facilities.

This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution (CC BY) license (http://creativecommons.org/licenses/by/4.0/).Fusarium causes significant post-harvest quality losses and mycotoxin contamination instored wheat but the colonisation dynamics of the grain and how this may be affected by the initialinoculum position in the grain mass is poorly understood. This study examined the 3D growthkinetics and mycotoxin production (deoxynivalenol and zearalenone) by F. graminearum duringhyphal colonisation from different initial inoculum positions in wheat microcosms (top-centre,bottom-centre, and bottom-side) maintained at two water activities (aw; 0.95 and 0.97). Clear jarswere used to visually follow the colonisation dynamics. Fungal respiration and associated drymatter loss (DML) and ergosterol were also quantified. Colonisation dynamics was shown to beaffected by the inoculation position. At the end of the colonisation process, fungal respiration andDML were driven by the inoculation position, and the latter also by the prevailing aw. Fungalbiomass (ergosterol) was mainly affected by the aw. The initial inoculum position did not affect therelative mycotoxin production. There was a positive correlation between respiration and ergosterol,and between mycotoxin production and colonisation indicators. We suggest that spatially explicitpredictive models can be used to better understand the colonisation patterns and mycotoxincontamination of stored cereal commodities and to aid more effective post-harvest management.Peer reviewedFinal Published versio

Unveiling the effect of interacting forecasted abiotic factors on growth and aflatoxin B1 production kinetics by Aspergillus flavus

© 2020 Elsevier Ltd. All rights reserved. This manuscript is licensed under the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International Licence http://creativecommons.org/licenses/by-nc-nd/4.0/.The aim was to decipher the temporal impact of key interacting climate change (CC) abiotic factors of temperature (30 vs 37 °C), water activity (aw; 0.985 vs 0.930) and CO2 exposure (400 vs 1000 ppm) on (a) growth of Aspergillus flavus and effects on (b) gene expression of a structural (aflD) and key regulatory gene (aflR) involved in aflatoxin B1 (AFB1) biosynthesis and (c) AFB1 production on a yeast extract sucrose medium over a period of 10 days. A. flavus grew and produced AFB1 very early with toxin detected after only 48 h. Both growth and toxin production were significantly impacted by the interacting abiotic factors. The relative expression of the aflD gene was significantly influenced by temperature; aflR gene expression was mainly modulated by time. However, no clear relationship was observed for both genes with AFB1 production over the experimental time frame. The optimum temperature for AFB1 production was 30 °C. Maximum AFB1 production occurred between days 4–8. Exposure to higher CO2 conditions simulating forecasted CC conditions resulted in the amount of AFB1 produced in elevated temperature (37 °C) being higher than with the optimum temperature (30 °C) showing a potential for increased risk for human/animal health due to higher accumulation of this toxin.Peer reviewedFinal Accepted Versio

Impact of predicted climate change environmental conditions on the growth of Fusarium asiaticum strains and mycotoxins production on a wheat-based matrix

Fusarium asiaticum is a predominant fungal pathogen causing Fusarium Head Blight (FHB) in wheat and barley in China and is associated with approximately £201 million in annual losses due to grains contaminated with mycotoxins. F. asiaticum produces deoxynivalenol and zearalenone whose maximum limits in cereals and cereals-derived products have been established in different countries including the EU. Few studies are available on the ecophysiological behaviour of this fungal pathogen, but nothing is known about the impact of projected climate change scenarios on its growth and mycotoxin production. Therefore, this study aimed to examine the interacting effect of i) current and increased temperature (25 vs 30 °C), ii) drought stress variation (0.98 vs 0.95 water activity; aw) and iii) existing and predicted CO2 concentrations (400 vs 1000 ppm) on fungal growth and mycotoxin production (type B trichothecenes and zearalenone) by three F. asiaticum strains (CH024b, 82, 0982) on a wheat-based matrix after 10 days of incubation. The results showed that, when exposed to increased CO2 concentration (1000 ppm) there was a significant reduction of fungal growth compared to current concentration (400 ppm) both at 25 and 30 °C, especially at 0.95 aw. The multi-mycotoxin analysis performed by LC-MS/MS qTRAP showed a significant increase of deoxynivalenol and 15-acetyldeoxynivalenol production when the CH024b strain was exposed to elevated CO2 compared to current CO2 levels. Zearalenone production by the strain 0982 was significantly stimulated by mild water stress (0.95 aw) and increased CO2 concentration (1000 ppm) regardless of the temperature. Such results highlight that intraspecies variability exist among F. asiaticum strains with some mycotoxins likely to exceed current EU legislative limits under prospected climate change conditions

Study Protocol of Coaching End-of-Life Palliative Care for Advanced Heart Failure Patients and Their family Caregivers in Rural Appalachia: A Randomized Controlled Trial

Background Heart failure (HF) afflicts 6.5 million Americans with devastating consequences to patients and their family caregivers. Families are rarely prepared for worsening HF and are not informed about end-of-life and palliative care (EOLPC) conservative comfort options especially during the end stage. West Virginia (WV) has the highest rate of HF deaths in the U.S. where 14% of the population over 65 years have HF. Thus, there is a need to investigate a new family EOLPC intervention (FamPALcare), where nurses coach family-managed advanced HF care at home. Methods This study uses a randomized controlled trial (RCT) design stratified by gender to determine any differences in the FamPALcare HF patients and their family caregiver outcomes versus standard care group outcomes (N = 72). Aim 1 is to test the FamPALcare nursing care intervention with patients and family members managing home supportive EOLPC for advanced HF. Aim 2 is to assess implementation of the FamPALcare intervention and research procedures for subsequent clinical trials. Intervention group will receive routine standard care, plus 5-weekly FamPALcare intervention delivered by community-based nurses. The intervention sessions involve coaching patients and family caregivers in advanced HF home care and supporting EOLPC discussions based on patients’ preferences. Data are collected at baseline, 3, and 6 months. Recruitment is from sites affiliated with a large regional hospital in WV and community centers across the state. Discussion The outcomes of this clinical trial will result in new knowledge on coaching techniques for EOLPC and approaches to palliative and end-of-life rural home care. The HF population in WV will benefit from a reduction in suffering from the most common advanced HF symptoms, selecting their preferred EOLPC care options, determining their advance directives, and increasing skills and resources for advanced HF home care. The study will provide a long-term collaboration with rural community leaders, and collection of data on the implementation and research procedures for a subsequent large multi-site clinical trial of the FamPALcare intervention. Multidisciplinary students have opportunity to engage in the research process. Trial registration ClinicalTrials.gov NCT04153890, Registered on 4 November 201
