The qualification of food security in time and space must analyze not only the three components it covers but also the relationships that these three components maintain. Climate change contributes to food insecurity, but it is not the only factor. To address food insecurity in various forms, greater food security must be combined with improved sustainable agricultural practices with minimal strain on the environment. This review of literature insists on the principles of food security, which in particular allows a better understanding of food insecurity in developing countries and favors a greater contribution of agriculture and food systems in general to nutritional progress.展开更多

Infectious diseases in particular cause enormous morbidity and mortality. Diseases which afflict both western and developing countries are often seen in more florid forms in poorer countries. Innovative techniques continuously improve and update gastroenterological practice. However, advances in diagnosis and treatment which are commonplace in the West, have yet to reach many developing countries. Clinical guidelines, based on these advances and collated in resource-rich environments, lose their relevance outside these settings. In this two-part review, we first highlight the global burden of gastroenterological disease in three major areas： diarrhoeal diseases, hepatitis B, and Helicobacter pylori. Recent progress in their management is explored, with consideration of future solutions. The second part of the review focuses on the delivery of clinical services in developing countries. Inadequate numbers of healthcare workers hamper efforts to combat gastroenterological disease. Reasons for this shortage are examined, along with possibilities for increased specialist training. Endoscopy services, the mainstay of gastroenterology in the West, are in their infancy in many developing countries. The challenges faced by those se^ing up a service are illustrated by the example of a Nigerian endoscopy unit. Finally, we highlight the limited scope of many clinical guidelines produced in western countries. Guidelines which take account of resource limitations in the form of ＂cascades＂ are advocated in order to make these guidelines truly global. Recognition of the different working conditions facing practitioners worldwide is an important step towards narrowing the gap between gastroenterology in rich and poor countries.展开更多

The availability of new, simple, very sensitive and specific serological tests （anti-gliadin, anti- endomysium and anti-transglutaminase antibody assays） have shown that celiac disease is common not only in Europe and in people of European ancestry but also in the developing countries where the major staple diet is wheat （Southern Asia, the Middle East, North West and East Africa, South America）, both in the general population and in the groups at risk. Gluten intolerance thus appears to be a widespread public health problem and an increased level of awareness and clinical suspicion are needed in the New World where physicians must learn to recognize the variable clinical presentations （classical, atypical and silent forms） of celiac disease. In the developing countries, both serological screening in the general population and serological testing in groups at risk are necessary for an early identification of celiac patients. The gluten-free diet poses a challenging public health problem in the developing countries, especially since commercial gluten-free products are not available.展开更多

The high prevalence is due to failure to adopt appropriate measure to confine the spread of infection. Most hepatitis B patients present with advanced diseases. Although perinatal transmission is believed to be an important mode, most infections in the developing world occur in childhood and early adulthood. Factors in developing countries associated with the progression of chronic hepatitis B (CHB) include co-infections with human immunodeficiency virus, delta hepatitis virus, hepatitis C virus, alcohol intake and aflatoxin. Treatment protocols extrapolated from developed countries may need modifications according to the resources available. There is some controversy as to when to start treatment, with what medication and for how long? There is now enough evidence to support that hepatitis B patients should be considered for treatment if they show persistently elevated abnormal aminotransferase levels in the last 6 mo, checked on at least three separate occasions, and a serum hepatitis B virus DNA level of > 2000 IU/mL. Therapeutic agents that were approved by Pure Food and Drug Administration are now available in many developing countries. These include standard interferon (INF)-α, pegylated INF-α, lamivudine, adefovir, entecavir and telbivudine. Drug resistance has emerged as a major challenge in the management of patients with CHB. The role of the universal vaccination program for effective control of hepatitis B cannot be emphasized enough.展开更多

The prevalence of the disease is expected to increase worldwide, as we are encountering the global obesity epidemic and the trend in developing countries toward the Western lifestyles. However, it looks that there are some differences between the demographic and epidemiologic features of NAFLD in developing and developed countries.展开更多

The most serious complication is typhoid intestinal perforation(TIP), observed in 0.8% to 39%, with a striking rate difference between high-income and low-middle-income countries. Although the mortality rate consequent to TIP in resource-poor countries is improved in the last decades, it is still fluctuating from 5% to 80%, due to surgical-and not surgical-related constraints. Huge economic costs and long timelines are required to provide a short-to middle-term solution to the lack of safe water and sanitation. Inherent limitations of the currently available diagnostic tools may lead to under-evaluation as well as over-evaluation of the disease, with consequent delayed treatment or inappropriate, excessive antibiotic use, hence increasing the likelihood of bacterial resistance. There is a need for immunization programs in populations at greatest risk, especially in sub-Saharan Africa. Uniform surgical strategies and guidelines, on the basis of sound or prospective surgical studies and adapted to the local realities, are still lacking. Major drawbacks of the surgical treatment are the frequent delays to surgery, either for late diagnosis or for difficult transports, and the unavailable appropriate intensive care units in most peripheral facilities. As a consequence, poor patient's conditions at presentation, severe peritoneal contamination and unsuitable postoperative care are the foremost determinant of surgical morbidity and mortality.展开更多

These developing countries will be required to provide basic safety information on their chemical products, including data developed from chemical and toxicologic testing. These data must be developed in accordance with the national requirements of the importing country. Many importing countries have adopted the OECD Test Guidelines and the OECD Principles of Good Laboratory Practice (GLP) as primary guidance to assure the quality of laboratory data. These procedures provide a basis for internationally acceptable data. Several countries have incorporated many of these provisions into their national laws or administrative procedures. These procedures describe the process of documenting the conduct of laboratory studies, including recording of data, reporting of study results, and storage of data gathered. This process is intended to assure the quality and integrity of the data so that, if required, the study can be reconstructed by an auditor or an inspector. Details of these procedures and their applicability to the international chemical trade are discussed. 1989 Academic Press, Inc.展开更多

文摘In the past, celiac disease was believed to be a chronic enteropathy, almost exclusively affecting people of European origin. The availability of new, simple, very sensitive and specific serological tests （anti-gliadin, anti- endomysium and anti-transglutaminase antibody assays） have shown that celiac disease is common not only in Europe and in people of European ancestry but also in the developing countries where the major staple diet is wheat （Southern Asia, the Middle East, North West and East Africa, South America）, both in the general population and in the groups at risk.

文摘This paper presents a Spatial Decision Support System for local governments of developing countries.It allows municipality government,enterprises,scientific community and civil society to address decision problems using GIS.The framework is supported by four modules of information technologies:Environmental Decision Support Database,Data Manipulation,Decision Support,and Mapping.A case study is presented covering the implementation of this framework in one municipality of Cuba.An example of land suitability planning for coconut crops is used to evaluate the system performance and usability.Results show local municipalities are able to use this framework to solve local decision problems using state of the art decision making even with low infrastructure development.
文摘TO THE EDITORNonalcoholic fatty liver disease (NAFLD) is an increasingly known medical entity with high prevalence, about 1 0 to 24 percent in general population and up to 74% in obese population[1]. The prevalence of the disease is expected to increase worldwide, as we are encountering the global obesity epidemic and the trend in developing countries toward the Western lifestyles. However, it looks that there are some differences between the demographic and epidemiologic features of NAFLD in developing and developed countries.
文摘Developing countries face a number of unique problems related to the hazards of chemicals. The WHO International Program on Chemical Safety may play a useful role by working jointly with Member Nations and such international organizations as FAO, UNEP. and ILO. (c)1990 Academic Press. Inc.
文摘Typhoid fever is a public health challenge mostly concentrated in impoverished, overcrowded areas of the developing world, with lack of safe drinking and sanitation. The most serious complication is typhoid intestinal perforation(TIP), observed in 0.8% to 39%, with a striking rate difference between high-income and low-middle-income countries. Although the mortality rate consequent to TIP in resource-poor countries is improved in the last decades, it is still fluctuating from 5% to 80%, due to surgical-and not surgical-related constraints. Huge economic costs and long timelines are required to provide a short-to middle-term solution to the lack of safe water and sanitation. Inherent limitations of the currently available diagnostic tools may lead to under-evaluation as well as over-evaluation of the disease, with consequent delayed treatment or inappropriate, excessive antibiotic use, hence increasing the likelihood of bacterial resistance. There is a need for immunization programs in populations at greatest risk, especially in sub-Saharan Africa. Uniform surgical strategies and guidelines, on the basis of sound or prospective surgical studies and adapted to the local realities, are still lacking. Major drawbacks of the surgical treatment are the frequent delays to surgery, either for late diagnosis or for difficult transports, and the unavailable appropriate intensive care units in most peripheral facilities. As a consequence, poor patient's conditions at presentation, severe peritoneal contamination and unsuitable postoperative care are the foremost determinant of surgical morbidity and mortality.
文摘As developing countries become more involved in the international chemical trade, they must adhere to certain requirements for importation of their chemicals into foreign countries. These developing countries will be required to provide basic safety information on their chemical products, including data developed from chemical and toxicologic testing. These data must be developed in accordance with the national requirements of the importing country. Many importing countries have adopted the OECD Test Guidelines and the OECD Principles of Good Laboratory Practice (GLP) as primary guidance to assure the quality of laboratory data. These procedures provide a basis for internationally acceptable data. Several countries have incorporated many of these provisions into their national laws or administrative procedures. These procedures describe the process of documenting the conduct of laboratory studies, including recording of data, reporting of study results, and storage of data gathered. This process is intended to assure the quality and integrity of the data so that, if required, the study can be reconstructed by an auditor or an inspector. Details of these procedures and their applicability to the international chemical trade are discussed. 1989 Academic Press, Inc.
文摘Radiation therapy(RT)is considered one of the cornerstone modalities of treatment for different cancer types.The preparation and delivery of RT requires a number of staff members from different disciplines within the radiation oncology department.Since the emergence of the corona virus disease 2019(COVID-19)pandemic,RT,similar to other cancer care modalities,has been adapted to minimize patient and staff exposure without compromising the oncological outcomes.This was reflected in the dramatic practice changes that occurred in the past year to address the lockdown restrictions and fulfill the infection control requirements.RT practices differ across regions based on financial and training levels,and developing countries with limited resources have struggled to maintain radiation treatment services at a level equivalent to that in developed countries while following pandemic control guidelines.The response during the COVID-19 pandemic varied between developing countries according to the infection rate and RT technological capabilities.In this editorial,we review recently published articles addressing radiotherapy practice reports during the COVID-19 pandemic in developing countries.
文摘Objective:To determine the barriers of joining in-vitro fertilization(IVF)programs among infertile couples in developing countries.Methods:This study assessed infertile couples and the barriers or associated factors resulting in delayed decision-making of joining IVF program by searching databases PubMed,ScienceDirect,EBSCO,ClinicalKey,and Cochrane Library from inception until December 31,2021.Additional search strategies were snowballing literature search and citation tracking.Results:Eleven articles were included in the scoping review.The cost was the greatest barrier of joining IVF program.Limited access and lack of assisted reproductive technology centers,few qualified infertility trained staff,insufficient government support,low priority in government policy,along with sociocultural factors,such as religion and false beliefs or myths were also majorly considered to be associated obstacles.Conclusions:The main barrier associated with IVF program among infertile couples in developing countries is the high cost of the IVF services.
