HIV patients with digestive system disease significantly more often had changes to their therapy regiment, interruptions in treatment and more often experienced side effects.
Conclusions Digestive system disease becomes more common with the progression of HIV infection. Comorbidity of HIV infection and digestive system disease is characterized by changes in general clinical, biochemical and immunological blood parameters and patients with digestive system comorbidities more often have a poor virological response to antiretroviral therapy.

Introduction Lifestyle modification, including changing eating habits, plays an essential role in the prevention of stroke. The aim The study aimed to assess the nutritional prevention of cerebrovascular diseases in adult inhabitants of Poland.
Material and Methods The study was conducted using the author's questionnaire among 145 women and 76 men, aged 18 - 30 (53.9%) and 50 - 70 (46.1%) years.
Results The following stroke risk factors were found in the examined group overweight or obesity (46.6%), lack of regular physical activity (48%), smoking (33%), hypertension (22.1%), dyslipidemia (8.6%), diabetes (5.9%), and cardiac arrhythmias (6.3%). The younger subjects compared to older ones more often declared the daily consumption of whole-grain cereal products and vegetables, fish at least once a week, and they preferred vegetable oils. On the other hand, older subjects declared the consumption of sweets, sweet drinks, salt, and fast food less frequently than younger ones. Also, fruits were more often chcular diseases is still necessary and should be age-appropriate.
The aim To determine a possible role of nitric oxide system as one of the pathogenesis links in Stevens-Johnson syndrome depending on the severity of disease progression.
Material and methods We examined 11 patients with Stevens-Johnson syndrome. The function of nitric oxide system (NO - NOS) in blood serum was examined.
Results During the study of nitric oxide system (NO-NOS) in patients with SJS, it was observed that NO2¯ level was increased by 1.53 times, NO3¯ level - by 3.33 times, activity of total NOS - by 5.78 times, constitutive (cNOS) - by 1.81 times and inducible (iNOS) - by 13.36 times.
Conclusions The intensity of nitric oxide system function was studied in patients with Stevens-Johnson syndrome and dependence of changes of its parameters from the clinical signs of disease was detected. It was found that the determination of nitrite and nitrate anion levels in blood serum can be used for the purpose of predicting the disease course and choosing the therapy methods for the patients with SJS.

Lipomannan (LM) and lipoarabinomannan (LAM) are structural and immunomodulatory components of this cell envelope. LM/LAM biosynthesis involves a number of mannosyltransferases and acyltransferases, and MptA is an α1,6-mannosyltransferase involved in the final extension of the mannan chain. Recently, we reported the periplasmic protein LmeA being involved in the maturation of the mannan backbone in Mycobacterium smegmatis Here, we examined the role of LmeA under stress conditions. We found that lmeA transcription was upregulated under two stress conditions stationary growth phase and nutrient starvation. Under both conditions, LAM was decreased, but LM was relatively stable, suggesting that maintaining the cellular level of LM under stress is important. Surprisingly, the protein levels of MptA were decreased in an lmeA deletion (ΔlmeA) mutant starvation, while the levels of another related lipoglycan, lipomannan (LM), stay relatively constant. The persistence of LM under stress correlated with the maintenance of two key mannosyltransferases, MptA and MptC, in the LM biosynthetic pathway. We further showed that the stress exposures lead to the upregulation of lmeA gene expression and that the periplasmic protein LmeA plays a key role in maintaining the enzyme MptA and its product LM under stress conditions. These findings reveal new aspects of how lipoglycan biosynthesis is regulated under stress conditions in mycobacteria.Clostridioides difficile is the leading cause of nosocomial infection and is the causative agent of antibiotic-associated diarrhea. The severity of the disease is directly associated with toxin production, and spores are responsible for the transmission and persistence of the organism. Previously, we characterized sin locus regulators SinR and SinR' (we renamed it SinI), where SinR is the regulator of toxin production and sporulation. The SinI regulator acts as its antagonist. In Bacillus subtilis, Spo0A, the master regulator of sporulation, controls SinR by regulating the expression of its antagonist, sinI However, the role of Spo0A in the expression of sinR and sinI in C. difficile had not yet been reported. In this study, we tested spo0A mutants in three different C. difficile strains, R20291, UK1, and JIR8094, to understand the role of Spo0A in sin locus expression. Western blot analysis revealed that spo0A mutants had increased SinR levels. Quantitative reverse transcription-PCR (qRT-PCR) analysis of its and toxin production in this pathogen.Candida albicans is an opportunistic fungal pathogen of humans known for its ability to cause a wide range of infections. One major virulence factor of C. albicans is its ability to form hyphae that can invade host tissues and cause disseminated infections. Here, we introduce a method based on atomic force microscopy to investigate C. albicans hyphae in situ on silicone elastomer substrates, focusing on the effects of temperature and antifungal drugs. Hyphal growth rates differ significantly for measurements performed at different physiologically relevant temperatures. Furthermore, it is found that fluconazole is more effective than caspofungin in suppressing hyphal growth. We also investigate the effects of antifungal drugs on the mechanical properties of hyphal cells. An increase in Young's modulus and a decrease in adhesion force are observed in hyphal cells subjected to caspofungin treatment. Young's moduli are not significantly affected following treatment with fluconazole; the adhesion force, however, increases. Overall, our results provide a direct means of observing the effects of environmental factors and antifungal drugs on C. albicans hyphal growth and mechanics with high spatial resolution.IMPORTANCECandida albicans is one of the most common pathogens of humans. One important virulence factor of C. albicans is its ability to form elongated hyphae that can invade host tissues and cause disseminated infections. Here, we show the effect of different physiologically relevant temperatures and common antifungal drugs on the growth and mechanical properties of C. albicans hyphae using atomic force microscopy. We demonstrate that minor temperature fluctuations within the normal range can have profound effects on hyphal cell growth and that different antifungal drugs impact hyphal cell stiffness and adhesion in different ways.Since its emergence in the United States in 2014, enterovirus D68 (EV-D68) has been and is associated with severe respiratory diseases and acute flaccid myelitis. Even though EV-D68 has been shown to replicate in different neuronal cells in vitro, it is currently poorly understood which viral factors contribute to the ability to replicate efficiently in cells of the central nervous system and whether this feature is a clade-specific feature. Here, we determined the replication kinetics of clinical EV-D68 isolates from (sub)clades A, B1, B2, B3, and D1 in human neuroblastoma cells (SK-N-SH). Subsequently, we compared sequences to identify viral factors associated with increased viral replication. All clinical isolates replicated in SK-N-SH cells, although there was a large difference in efficiency. Efficient replication of clinical isolates was associated with an amino acid substitution at position 271 of VP1 (E271K), which was acquired during virus propagation in vitro Recognition of heparan sulfate in additides did not reveal clade-specific phenotypic characteristics. However, we did show that viruses which acquired a cell culture-adapted amino acid substitution in VP1 (E271K) recognized heparan sulfate as an additional receptor. Recognition of heparan sulfate resulted in an increase in attachment, infection, and replication in neuroblastoma cells compared with viruses without this specific amino acid substitution. The ability of EV-D68 viruses to acquire cell culture-adaptive substitutions which have a large effect in experimental settings emphasizes the need to sequence virus stocks.
