BACKGROUND

As we move toward a polio-free world, the challenge for the polio program is to create an unrelenting focus on smaller areas where the virus is still present, where children are being repeatedly missed, where immunity levels are low, and where surveillance is weak.

OBJECTIVE

This article aimed to describe a possible solution to address weak surveillance systems and document the outcomes of the deployment of the Auto-Visual Acute Flaccid Paralysis Detection and Reporting (AVADAR) project.

METHODS

This intervention was implemented in 99 targeted high-risk districts with concerns for silent polio circulation from eight countries in Africa between August 1, 2017, and July 31, 2018. A total of 6954 persons (5390 community informants and 1564 health workers) were trained and equipped with a smartphone on which the AVADAR app was configured to allow community informants to send alerts on suspected acute flaccid paralysis (AFP) and allow health worker to use electronic checklists for investigation of such alerts. The AVADAR and Open Data Kit ONA servers were at the center of the entire process. A dashboard system and coordination teams for monitoring and supervision were put in place at all levels.

RESULTS

Overall, 96.44% (24,142/25,032) of potential AFP case alerts were investigated by surveillance personnel, yielding 1414 true AFP cases. This number (n=1414) reported through AVADAR was higher than the 238 AFP cases expected during the study period in the AVADAR districts and the 491 true AFP cases reported by the traditional surveillance system. A total of 203 out of the 1414 true AFP cases reported were from special population settings, such as refugee camps and insecure areas. There was an improvement in reporting in silent health areas in all the countries using the AVADAR system. Finally, there were 23,473 reports for other diseases, such as measles, diarrhea, and cerebrospinal meningitis, using the AVADAR platform.

CONCLUSIONS

This article demonstrates the added value of AVADAR to rapidly improve surveillance sensitivity. AVADAR is capable of supporting countries to improve surveillance sensitivity within a short interval before and beyond polio-free certification.

BACKGROUND

The 2019 novel coronavirus (SARS-COV-2) originated in the central Chinese city, Wuhan by end of December 2019.Pakistan reported its first 2 confirmed cases,on26th February 2020 linked to travel history of Iran.

OBJECTIVE

The study was conducted to see the trend of covid infection growth and doubling time in Pakistan from an early containment state to much belated exponential rise pattern .

METHODS

This study is based on analysis of the publicly available data on COVID-19 from Ministry of National Health Services Regulations and Coordination covid-19 dashboard and National Institute Health Islamabad(NIH) situation reports from 26th Feb to 30th March2020.

RESULTS

A total of 1875 COVID-19 patients has been reported with 25 deaths,11 critically ill and 58 recoveries. Punjab has highest number of confirmed cases (593)Sindh(508),Khyber Pakhtun Khawa (195) Baluchistan(144)Gilgit Baltistan(128),Islamabad Capital territory (51) Azad Jammu Kashmir (6). Majority of effected patients are male(64%).Iran Zairian are making 49% of positive patents Local transmission cases stands at 29%.Daily cases surge is 12.3% increase per day. 30th March 2020 witnessing highest reported cases so far (240 new Cases). Pakistan reached its first 100 confirmed cases on 16th March,2020,20 days after first reported case. The case doubling time was 3 days initially after first cases then it was reported as three days and then five days till 30th March 2020

CONCLUSIONS

Grave mishandling, lack of quarantine facility and limited testing capacity at Taftan border crossing resulted in importation of virus in country.Cumulative confirmed case count in Pakistan is still in sub-exponential growth pattern. Stringent risk mitigation measures by provinces and Federal being implemented have resulted in slow rate of infection growth with reduced infection doubling rate in days. Pakistan with limited testing capacity of 2000-3000 tests per day needs Extremely comprehensive testing regime is required to halt the community transmission leading to exponential increase in cases.

Swi-independent 3a and 3b (Sin3a and Sin3b) are paralogous transcriptional coregulators that direct cellular differentiation, survival, and function. Here, we report that mouse Sin3a and Sin3b are coproduced in most pancreatic cells during embryogenesis but become much more enriched in endocrine cells in adults, implying continued essential roles in mature endocrine cell function. Mice with loss of Sin3a in endocrine progenitors were normal during early postnatal stages but gradually developed diabetes before weaning. These physiological defects were preceded by the compromised survival, insulin-vesicle packaging, insulin secretion, and nutrient-induced Ca2+ influx of Sin3a-deficient β-cells. RNA sequencing coupled with candidate chromatin immunoprecipitation assays revealed several genes that could be directly regulated by Sin3a in β-cells, which modulate Ca2+/ion transport, cell survival, vesicle/membrane trafficking, glucose metabolism, and stress responses. Finally, mice with loss of both Sin3a and Sin3b in multipotent embryonic pancreatic progenitors had significantly reduced islet cell mass at birth, caused by decreased endocrine progenitor production and increased β-cell death. These findings highlight the stage-specific requirements for the presumed “general” coregulators Sin3a and Sin3b in islet β-cells, with Sin3a being dispensable for differentiation but required for postnatal function and survival.

NADPH facilitates glucose-stimulated insulin secretion (GSIS) in pancreatic islets (PIs) of β-cells through an as yet unknown mechanism. We found NADPH oxidase isoform 4 (NOX4) to be the main producer of cytosolic H2O2, which is essential for GSIS; an increase in ATP alone was insufficient for GSIS. The fast GSIS phase was absent from PIs from NOX4-null, β-cell–specific knockout mice (NOX4βKO) (though not from NOX2 knockout mice) and from NOX4-silenced or catalase-overexpressing INS-1E cells. Lentiviral NOX4 overexpression or H2O2 rescued GSIS in PIs from NOX4βKO mice. NOX4 silencing suppressed Ca2+ oscillations, and the patch-clamped KATP channel opened more frequently when glucose was high. Mitochondrial H2O2, decreasing upon GSIS, provided alternative redox signaling when 2-oxo-isocaproate or fatty acid oxidation formed superoxides through electron-transfer flavoprotein:Q-oxidoreductase. Unlike GSIS, such insulin secretion was blocked with mitochondrial antioxidant SkQ1. Both NOX4 knockout and NOX4βKO mice exhibited impaired glucose tolerance and peripheral insulin resistance. Thus, the redox signaling previously suggested to cause β-cells to self-check hypothetically induces insulin resistance when it is absent. In conclusion, increases in ATP and H2O2 constitute an essential signal that switches on insulin exocytosis for glucose and branched-chain oxoacids as secretagogues (it does so partially for fatty acids). Redox signaling could be impaired by cytosolic antioxidants; hence, those targeting mitochondria should be preferred for clinical applications to treat (pre)diabetes at any stage.

HLA-DQA1 and -DQB1 are strongly associated with type 1 diabetes (T1D), and DQ8.1 and DQ2.5 are major risk haplotypes. Next-generation targeted sequencing of HLA-DQA1 and -DQB1 in Swedish newly diagnosed 1- to 18 year-old patients (n = 962) and control subjects (n = 636) was used to construct abbreviated DQ haplotypes, converted into amino acid (AA) residues, and assessed for their associations with T1D. A hierarchically organized haplotype (HOH) association analysis allowed 45 unique DQ haplotypes to be categorized into seven clusters. The DQ8/9 cluster included two DQ8.1 risk and the DQ9 resistant haplotypes, and the DQ2 cluster included the DQ2.5 risk and DQ2.2 resistant haplotypes. Within each cluster, HOH found residues α44Q (odds ratio [OR] 3.29, P = 2.38 * 10−85) and β57A (OR 3.44, P = 3.80 * 10−84) to be associated with T1D in the DQ8/9 cluster representing all ten residues (α22, α23, α44, α49, α51, α53, α54, α73, α184, β57) due to complete linkage disequilibrium (LD) of α44 with eight such residues. Within the DQ2 cluster and due to LD, HOH analysis found α44C and β135D to share the risk for T1D (OR 2.10, P = 1.96 * 10−20). The motif “QAD” of α44, β57, and β135 captured the T1D risk association of DQ8.1 (OR 3.44, P = 3.80 * 10−84), and the corresponding motif “CAD” captured the risk association of DQ2.5 (OR 2.10, P = 1.96 * 10−20). Two risk associations were related to GAD65 autoantibody (GADA) and IA-2 autoantibody (IA-2A) but in opposite directions. CAD was positively associated with GADA (OR 1.56, P = 6.35 * 10−8) but negatively with IA-2A (OR 0.59, P = 6.55 * 10−11). QAD was negatively associated with GADA (OR 0.88; P = 3.70 * 10−3) but positively with IA-2A (OR 1.64; P = 2.40 * 10−14), despite a single difference at α44. The residues are found in and around anchor pockets 1 and 9, as potential T-cell receptor contacts, in the areas for CD4 binding and putative homodimer formation. The identification of three HLA-DQ AAs (α44, β57, β135) conferring T1D risk should sharpen functional and translational studies.

One of the most important parameters of energy efficiency is to determine the heating and cooling requirements of the buildings and to develop the appropriate heating/cooling technology. In this study, the regional residence heating/cooling loads were determined in order to develop technology for regional heating/cooling systems in Turkey. Heating/cooling loads of the residences were made separately for each province according to the heating regions determined in accordance with TS 825. Fuel and electricity consumption, population, number of residences and meteorological data were used as the basis for determining the heating/cooling loads. Using the data obtained, an important source data was obtained to investigate the possibility of using alternative energy sources for each region or even every province.

Sustainable Management of Agricultural Resources: A Model Proposal For Agricultural Management Planning
Authors: BAL Şaziye , ÖZCAN Koray
Published: April 2020

Agriculture has a vital role as an economic sector for the sustainable development of countries besides its necessity for the continuity of human life. On the other hand, agricultural productivity is very open to negative changes that occurs from social, economic, physical and ecological fluctuations. Given that these pre–explainations, it is necessary to manage the agricultural areas/resources via a mechanism that deals with the changing socio–cultural relations, economic conditions and ecological resources with different dynamics and dimensions. The aim of this paper is to analyze a comperehensive management principles of the areas where there is a vast agricultural production and the contents and preparation steps of an agricultural management plan, seen as a strategic tools for sustainable management, protection, development and usage. The first method which are used for this research is literature review about resource management planning to describe the main steps of it and variation of management areas. Later the characteristic of Kumkale Major Plain evaluated in the scope of management area. Finally, a model for Sustainable Management of Agricultural Resources which provides a coordination and collaboration between stakeholders and describes the action plan focused on the sustainable management of agricultural resources to the future politics, actions with the responsible foundations is proposed for this kind of managable agricultural areas. In this framework, the Sustainable Management Model for Agricultural Resources (SMAR) is handled under 3 (three) submodel process management model, participation model, planning–implementation model. It is considered that this model presents an alternative management planning approach for academic–scientific research project and also contributes implementation projects focused on sustainable management of agricultural resources in the context of national and local goverments as decision maker.
Phaistos disc. A look from the 21st century.
Authors: ANDREEVA TATYANA
Published: April 2020

the Phaistos disk was made in the time following the expedition to the country of Punt, organized by Queen Hatshepsut. That is, in the Middle Kingdom, which coincides with the conclusions of other researchers of the artifact. The country of manufacture was most likely Egypt, which can be assumed, given the similarity of the disk signs and Egyptian hieroglyphs, as well as the presence of an outstanding sculptural and ceramic tradition in the country of the pharaohs. The manufacturing technology was the same for the disk, as for other clay products of the time, and there is no reason to consider the issue of seals (stamps) as a special form of processing this unique subject. Purpose of the disk: with caution, we assume that it was an object that serves to receive predictions. The signs most likely represent pictographic records, so the question of the language of the disc does not arise. For the same reason, it does not seem significant to consider the problem of the direction in which characters are read: in logograms, the order of the icons may not matter.

Published: April 2020

Modern lifestyles do influence Malaysian occupants to work long hours in a day in order to cope with large workloads and to meet a deadline. Majority of the occupants are overstressed, faced with negative emotions that lead to an unhealthy lifestyle. Studies show that nature is able to enhance human well-being by reconnecting human with natural elements in a built environment, which is known as biophilic design. Therefore, this study aims to create a biophilic design guideline to enhance occupants' well-being in heritage adaptive reuse indoor co-working space.  This study is conducted in the Heritage World Site (WHS) in George Town, Penang.  Mixed method research design was used to collect data from the site. Both qualitative and quantitative data were analysed using the triangulation method to validate the overall data and research by cross verifying the information from multiple methods to gather the data. The results proved that the existing biophilic design patterns do enhance co-workers' emotional well-being significantly and it can be used as design guideline. In addition, this study also investigated different ways of biophilic design patterns application which can affect the quality of biophilic experiences.
