The real place of infectious pathology in overall population morbidity

The statistical decrease of the proportion of infections in the structure of morbidity of the population reflects the existing classification of diseases when only acute diseases are classified with the group "infectious and parasitic diseases". The proportion of diseases caused by infective agents remains constantly high. According to WHO data, such diseases make up one-third of all diseases in the world. In Moscow the proportion of infectious diseases in all diseases registered among the inhabitants of this big city fluctuated within 36.1% and 49.7% during the period of 1926-1997.

The COVID-19 epidemic and other notifiable infectious diseases in China

Many infection control measures have been implemented to prevent the spread of SARS-CoV-2 during COVID-19 pandemic. We aimed to investigate the impact of COVID-19 epidemic on the other notifiable infectious diseases in China, including respiratory infectious diseases, diseases transmitted through the digestive tract and animal-borne diseases. Compared with 2019, the overall decline rate of respiratory infectious diseases in 2020 is the highest (60–90%), and the diseases transmitted by the digestive tract and animal-borne diseases are similar at 20–30%. Both hepatitis and sexually transmitted diseases decreased significantly in February, and there were basically no significant changes in other months compared with previous years. The series of measures taken by China government to prevent the spread of SARS-CoV-2 are also very effective in preventing the spread of respiratory infectious diseases. But they also have a certain degree of prevention against notifiable infectious diseases spread by other routes.     

Medico-genetic study of the population of Uzbekistan. VI. Hereditary pathology among the populations of 4 regions of the Kashkadarinskaia area]

The screening for families burdened with multiple cases of non-infectious diseases, the diagnostic of those diseases and the investigation of relations between the population structure and the distribution of hereditary diseases in 4 districts of the Kashkadarja province were carried out. On the basis of the data obtained the load of excessive hereditary diseases was calculated and nosological spectrum was described; it included more than 30 different diseases. The study of spatial distribution of recessive diseases has shown that the load of hereditary diseases may be accounted for the positive assortative matings. The high level of interpopulation migration prevents from the local accumulation of a certain hereditary disease.     

Therapeutic potency of crocin in the treatment of inflammatory diseases: Current status and perspective

Crocin is the major component of saffron, which is used in phytomedicine for the treatment of several diseases including diabetes, fatty liver, depression, menstruation disorders, and, of special interest in this review, inflammatory diseases. Promising selective anti-inflammatory properties of this pharmacological active component have been observed in several studies. Saffron has been shown to exert anti-inflammatory properties against several inflammatory diseases and can be used as a novel therapeutic agent for the treatment of inflammatory diseases either alone or in combination with other standard anti-inflammatory agents. This review summarizes the protective role of saffron and its pharmacologically active constituents in the pathogenesis of inflammatory diseases including digestive diseases, dermatitis, asthma, atherosclerosis, and neurodegenerative diseases for a better understanding and hence a better management of these diseases.     

Extragastric manifestations of Helicobacter pylori infection

In the previous year, some extragastric diseases, possibly linked to Helicobacter pylori infection, have been largely investigated. There are, in fact, several studies concerning cardiovascular diseases, lung diseases, hematologic diseases, eye and skin diseases, hepatobiliary diseases, diabetes mellitus, and neurological disorders. Among them, the relationship between bacterial CagA positivity and coronary heart disease is reportedly emphasized. Concerning normal tension glaucoma, new interesting data are playing in favor of the association with H. pylori infection. For other diseases, there are many interesting results, although more studies are needed to clarify the reality of the proposed association.     

The influence of foliar diseases and their control by selective fungicides on a range of groundnut (Arachis hypogaea L.) genotypes

Twenty groundnut genotypes were grown with various spray treatments which controlled either, only rust, or only leaf spot diseases, or all of these diseases or none of them. The genotypes varied in their resistance to these diseases, some having resistance to only one disease and some having resistance or susceptibility to all the diseases. Chemical control of the diseases resulted in variations in leaf area protection and in yield which were specific to each genotype. For some genotypes the diseases had little influence on yield and foliage, while for others yield and remaining green leaf were varied greatly by the control of diseases. For many of the genotypes the yield achieved was well related to variations in the green leaf remaining at maturity as a result of the spray treatments. Genotypes with good levels of genetic resistance did not have high yield potentials while those with the best yields when diseases were controlled were the most susceptible to these diseases.     

Iron and copper toxicity in diseases of aging, particularly atherosclerosis and Alzheimer's disease

In this review, we point out that natural selection does not act to lessen human diseases after the reproductive and caregiving period and that normal levels of iron and copper that may be healthy during the reproductive years appear to be contributing to diseases of aging and possibly the aging process itself. It is clear that oxidant damage contributes to many of the diseases of aging, such as atherosclerosis, Alzheimer's disease, Parkinson's diseases, diabetes, diseases of inflammation, diseases of fibrosis, diseases of autoimmunity, and so on. It is equally clear that both iron and copper can contribute to excess production of damaging reactive oxygen species through Fenton chemistry. Here, we examine the evidence that "normal" levels of iron and copper contribute to various diseases of aging.

Neurodegenerative amyloidoses: the yeast model

More than 20 human diseases are related to protein misfolding which causes formation of amyloids, fibrillar aggregates of normally soluble proteins. Such diseases are called amyloid diseases or amyloidoses. Of them only prion diseases are transmissible. Amyloids of the prion type are described in lower eukaryotes. However, in contrast to mammalian prions, which cause incurable neurodegenerative diseases, prions of lower eukaryotes are related to some non-chromosomally inherited phenotypic traits. Here we summarize the results of studies of prions of the yeast Saccharomyces cerevisiae and of the use of yeast model for investigation of some human amyloidoses, such as prion diseases, Alzheimer's, Parkinson's, and Huntington's diseases.     

Emerging and re-emerging bacterial diseases in India

There has been a remarkable progress in the prevention, control and even eradication of infectious diseases with improved hygiene and development of antimicrobials and vaccines. However, infectious diseases still remain a leading cause of global disease burden with high morbidity and mortality especially in the developing world. Furthermore, there have been threats of new diseases during the past three decades due to the evolution and adaptation of microbes and the re-emergence of old diseases due to the development of antimicrobial resistance and the capacity to spread to new geographic areas. The impact of the emerging and re-emerging diseases in India has been tremendous at socioeconomic and public health levels. Their control requires continuing surveillance, research and training, better diagnostic facilities and improved public health system. Emerging and reemerging zoonotic diseases, foodborne and waterborne diseases and diseases caused by multiresistant organisms constitute the major threats in India. This review of bacterial emerging and re-emerging diseases should be of critical importance to microbiologists, clinicians, public health personnel and policy makers in India.     

Neglected Fungal Diseases in Sub-Saharan Africa: A Call to Action

Despite the considerable morbidity and mortality associated with fungal diseases in sub-Saharan Africa, it is notable that these diseases have been omitted from an expanded list of neglected tropical diseases. Inextricably tied together with HIV/AIDS and tuberculosis in sub-Saharan Africa, important fungal diseases such as cryptococcal meningitis and Pneumocystis jirovecii pneumonia (PCP) manifest as relatively common and deadly AIDS-defining opportunistic infections, often masked by and comorbid with tuberculosis. Others, such as mycetoma, which manifest as a debilitating and deforming illness primarily affecting rural adults, directly affect the socioeconomic productivity of rural communities. Lack of adequate diagnostic tests makes identifying the true disease burden due to fungal diseases difficult. To highlight the devastating impact of fungal diseases on the health and socioeconomic circumstances of sub-Saharan Africa’s poorest people and to increase the profile of efforts to control and prevent these diseases, we propose that the following fungal diseases be added to the list of neglected tropical diseases: cryptococcal meningitis, PCP, mycetoma, histoplasmosis, sporotrichosis, and blastomycosis. By outlining the prevalence, distribution, and disease burden of these fungal diseases in sub-Saharan Africa in this review, we hope to provide information to prioritize strategies for detection, control, and prevention of the neglected fungal diseases.     

Cytokine imbalance in non-immunological chronic disease

Over the last decade, cytokine imbalances have been associated with a plethora of diseases. While the Th(1)/Th(2) paradigm is widely used to explain the pathogenesis of immunological diseases, the role of cytokine imbalances for non-immunological diseases is still incompletely defined. The major obstacle here is to assess the extent to which non-immunological diseases are influenced by inflammation. Non-immunological diseases cover the whole spectrum from those triggered by infection-as may be the case for Alzheimer's disease-to those where the immune system has no apparent impact at all. Examples of the latter are bone diseases, including post-menopausal osteoporosis and skeletal malformations. In between there are diseases such as intrinsic asthma and osteoarthritis where the impact of the immune system is unclear. Thus far, imbalances affecting tumour necrosis factor (TNF)-alpha and members of the interleukin (IL)-1 and the TGF superfamily have been found in association with all of these diseases. We speculate here that cytokine imbalance will be found in additional diseases and touch on the role in phylogeny of cytokines outside the immune system.     

Disease-Aging Network Reveals Significant Roles of Aging Genes in Connecting Genetic Diseases

One of the challenging problems in biology and medicine is exploring the underlying mechanisms of genetic diseases. Recent studies suggest that the relationship between genetic diseases and the aging process is important in understanding the molecular mechanisms of complex diseases. Although some intricate associations have been investigated for a long time, the studies are still in their early stages. In this paper, we construct a human disease-aging network to study the relationship among aging genes and genetic disease genes. Specifically, we integrate human protein-protein interactions (PPIs), disease-gene associations, aging-gene associations, and physiological system–based genetic disease classification information in a single graph-theoretic framework and find that (1) human disease genes are much closer to aging genes than expected by chance; and (2) diseases can be categorized into two types according to their relationships with aging. Type I diseases have their genes significantly close to aging genes, while type II diseases do not. Furthermore, we examine the topological characters of the disease-aging network from a systems perspective. Theoretical results reveal that the genes of type I diseases are in a central position of a PPI network while type II are not; (3) more importantly, we define an asymmetric closeness based on the PPI network to describe relationships between diseases, and find that aging genes make a significant contribution to associations among diseases, especially among type I diseases. In conclusion, the network-based study provides not only evidence for the intricate relationship between the aging process and genetic diseases, but also biological implications for prying into the nature of human diseases.     

JMJD3 in the regulation of human diseases

In recent years, many studies have shown that histone methylation plays an important role in maintaining the active and silent state of gene expression in human diseases. The Jumonji domain-containing protein D3 (JMJD3), specifically demethylate di- and trimethyllysine 27 on histone H3 (H3K27me2/3), has been widely studied in immune diseases, infectious diseases, cancer, developmental diseases, and aging related diseases. We will focus on the recent advances of JMJD3 function in human diseases, and looks ahead to the future of JMJD3 gene research in this review.     

Analysis of diversity of autosomal-recessive diseases in Russian populations]

The diversity of autosomal recessive (AR) diseases was studied in six Russian regions: the Kirov, Kostroma, and Bryansk oblasts; Adygea Republic; Krasnodar krai, and Marii El Republic (in the latter region, the Mari and Russian ethnic groups were studied separately). In total, more than 1.5 million people were studied. The spectrum of the AR diseases included 101 nosological forms; the total number of the affected subjects was 942. For all diseases, the prevalence rate in the region where they were found and the mean prevalence rate in the total population studied were calculated. Only seven AR diseases had prevalence rates of 1:50,000 or higher; however, this group contained about 50% of the patients. About half of the AR diseases (66) had an extremely low prevalence rate (1:877,483). Eleven diseases exhibit local accumulation. Accumulation of some or other diseases was only observed in four out of seven populations studied (Marii El, Adygea, and the Kirov and Bryansk oblasts). To determine the cause of the local accumulation of some diseases in populations, correlation analysis of the dependence of accumulation of hereditary diseases on the genetic structure of the populations studied was performed. The accumulation coefficients for AR and autosomal dominant (AD) diseases and the mean values of random inbreeding (Fst) in individual districts were calculated for all populations studied. The coefficients of the Spearman rank correlation between the accumulation coefficient and random inbreeding (Fst) were 0.68 and 0.86 for the AD and AR diseases, respectively. The correlation between the accumulation of AD and AR diseases was 0.86. The relationships found indicate that the diversity of AD and AR diseases, as well as the genetic load, distinctly depended on the population genetic structure and were largely determined by genetic drift.     

Emerging role of HMGB1 in lung diseases: friend or foe

Lung diseases remain a serious problem for public health. The immune status of the body is considered to be the main influencing factor for the progression of lung diseases. HMGB1 (high‐mobility group box 1) emerges as an important molecule of the body immune network. Accumulating data have demonstrated that HMGB1 is crucially implicated in lung diseases and acts as independent biomarker and therapeutic target for related lung diseases. This review provides an overview of updated understanding of HMGB1 structure, release styles, receptors and function. Furthermore, we discuss the potential role of HMGB1 in a variety of lung diseases. Further exploration of molecular mechanisms underlying the function of HMGB1 in lung diseases will provide novel preventive and therapeutic strategies for lung diseases.
