Currently, a large part of the world population does not have access to quality visual health services. Most of this population lives in developing countries, thus it is necessary to screen the general population to identify ocular abnormalities such as refractive errors and amblyopia in schoolchildren. The protocols for complete visual screening or examination vary widely regarding the type of tests and procedures, although most of them use visual acuity (VA) and refraction as the main diagnostic criteria. These clinical tests should have good quality and precision, that is, a high sensitivity and specificity. Unfortunately, in most clinical and epidemiological studies, the quality and accuracy of the tests used are unknown, which makes it difficult to compare results and to estimate the real conditions of visual problems in the population. Therefore, the objective of this literature review was to describe the main tests and protocols used in epidemiological and clinical studies for the detection of refractive errors in children.

(1) Background: According to the World Report on Vision published by WHO, 123.7 million people around the world have vision impairment due to uncorrected refractive errors. Vision impairment affects many aspects of our lives, and it is related to low academic performance; (2) Methods: A prospective and multicenter study has been carried out in 1400 optical centers in Spain. A visual screening was carried out by optometrists on children aged between 6 and 12; (3) Results: 6673 children of primary school have been checked. The multivariate analysis reveals that 5.2% of the poor academic performance is related to vision. Poor academic performance was independent and significantly affected by sex, age, near vision, hyperopia, binocular dysfunctions, and bad ocular motility; (4) Conclusions: Vision plays a key role in optimum academic performance; consequently, the early detection of refractive errors and other visual problems is essential to improve the academic performance of schoolchildren.

Background: Academic performance at different educational levels has become a very important subject of study in local, national and international institutions. A visual system working properly is critical to improving academic performance. It is important to check children’s vision during the different stages of elementary school. Methods: A visual screening was carried out in elementary school children, aged between 6 and 12, across Spain. The screening included: the collection of demographic data, surveys of children and families about their vision habits and a basic optometric screening to detect visual problems. Results: Children with bad academic performance had worse visual health than those with good academic performance. Conclusions: It would be highly recommendable to introduce policies that ensure the early detection of visual disorders in schools and primary care in order to improve the academic performance of elementary students.

Negative Effect

It is estimated that by 2050 the world population over the age of 60 will be 2 billion. Population ageing is occurring rapidly in LMIC. A clearly negative effect of rapid ageing of the population is the increase in the number of the people with dementia. Although dementia mainly affects older people, it is not a normal part of ageing. According to different estimates, between 2% and 10% of all cases of dementia start before the age of 65. The prevalence doubles with every five-year increment in age after 65. The number of people globally who are living with dementia in 2011 is estimated to be 35.6 million, and epidemiological studies indicate that this number is expected to grow at an alarming rate. It is estimated that numbers will nearly double every 20 years, to 65.7 million in 2030 and 115.4 million in 2050. The majority of these people will be living in LMIC.

Cover Test

Within 3-days-program almost 200 children and 50 adults had their vision checked by an international qualified team of eye specialists in the local school in Sapareva Banya. Visual acuity, objective and subjective refraction, color perception, binocular vision, cover test, pupillary reaction and other tests were performed. Apart from the ophthalmic examination, all the patients’ parents also filled in questionnaire regarding visual strain regimen, previous eye doctor visits and other details. The aim was to promote visual health, establish and possibly treat refractive errors and amblyopia, to facilitate access to specialized medical care, optical and optometrist’s service for children’s population of remote municipalities with population under 10 000 people. The visual screening of Sapareva Banya school children was of great value because only 38% of children had been examined before. There were no major deviations, severe anisometropia and ametropia values or very low visual acuity patients not wearing optical correction. A surprisingly high incidence of color vision deficiency was found 9, 2% males and 4, 3 % females.

In the last six decades, one of the most striking developments in international law is the emergence of a massive body of legal norms and procedures aimed at protecting human rights. In many countries, though, there is little relationship between international law and the actual protection of human rights on the ground. This book takes a fresh look at why it's been so hard for international law to have much impact in parts of the world where human rights are most at risk. The book argues that more progress is possible if human rights promoters work strategically with the group of states that have dedicated resources to human rights protection. These human rights “stewards” can focus their resources on places where the tangible benefits to human rights are greatest. Success will require setting priorities as well as engaging local stakeholders such as nongovernmental organizations and national human rights institutions. To date, promoters of international human rights law have relied too heavily on setting universal goals and procedures and not enough on assessing what actually works and setting priorities. This book illustrates how, with a different strategy, human rights stewards can make international law more effective and also safeguard human rights for more of the world population.

The Status

Almost 50 per cent of the world population is constituted by the women and they have been making substantial contribution to socio-economic development. But, unfortunately their tremendous contribution remains unrecognized and unnoticed in most of the developing and least developed countries causing the problem of poverty among them. Empowering women has become the key element in the development of an economy. With women moving forward, the family moves, the village moves and the nation moves. Hence, improving the status of women by way of their economic empowerment is highly called for. Entrepreneurship is a key tool for the economic empowerment of women around the world for alleviating poverty. Entrepreneurship is now widely recognized as a tool of economic development in India also. In this paper I have tried to discuss the reasons and role of Women Entrepreneurship with the help of Push and Pull factors. In the last I have also discussed the problems and the road map of Women Entrepreneurs development in India.

The Relationship

Research on the relationship between fertility and gender ideology revealed inconsistent results. In the present study, we argue that inconsistencies may be due to the fact that such relationship may be nonlinear. We hypothesize a U- shaped relationship between two dimensions of gender ideology (i.e. primacy of breadwinner role and acceptance of male privilege) and fertility rates. We conducted a cross-national analysis of 60 countries using data from the World Values Survey as well as the World Population Prospects 2019. Controlling for gross domestic product, we found support for a U-shaped relationship between gender ideology and fertility. Higher levels of fertility rates were found at lower and especially higher levels of traditional gender ideology, while a medium level of gender ideology was associated with the lowest fertility rate. This curvilinear relationship is in agreement with the phase of the gender revolution in which the country is located. Traditional beliefs are linked to a complementary division of private versus public sphere between sexes, while egalitarian attitudes are associated with a more equitable division. Both conditions strengthen fertility. Instead, as in the transition phase, intermediate levels of gender ideology’s support are associated with an overload and a difficult reconciliation of the roles that women have to embody (i.e. working and nurturing) so reducing fertility. The present study has contributed to the literature by addressing the inconsistencies of prior research by demonstrating that the relationship between gender ideology and fertility rates is curvilinear rather than linear.

H Pylori

Gastric cancer (GC) has a high mortality rate with a poor 5-year survival. Helicobacter pylori (H. pylori) is present as part of the normal flora of stomach. It is found in the gastric mucosa of more than half of the world population. This bacterium is involved in developing H. pylori-induced GC due to the regulation of different micro ribonucleic acid (miRNA or miR). miRNAs are small noncoding RNAs and are recognized as prognostic biomarkers for GC that may control gene expression. miRNAs may function as tumor suppressors, or oncogenes. In this review, we evaluated studies that investigated the ectopic expression of miRNAs in the prognosis of H. pylori positive and negative GC.
