Histological examinations showed that hepatocytes were swollen in the central part of the liver lobules, showed droplets and pycnotic nuclei, which were characterized by fatty degeneration. Small and large bowel enterocytes were damaged, sometimes pushed from the surface, and sometimes inflammatory reactions in the mucous membrane were observed.

Our results suggest that alimentary fatty liver in early state is not considered simply as a reversible alteration because it alters the entire body's redox homeostasis and establishes heart and serious metabolic diseases as well as hasten the development of gastrointestinal tumors.

Deregulation of autophagy is a key mechanism in the pathogenesis and progression of several liver diseases. Deficient autophagy can contribute to liver steatosis, to endoplasmic reticulum stress and to the progression of non-alcoholic fatty liver disease. Chronic alcohol consumption inhibits autophagy. The accumulated mutant protein in the endoplasmic reticulum can be degraded by autophagy in alpha-1-antitrypsin deficiency. Hepatitis C and B viruses may exploit the autophagy pathway to promote the own replication. Hepatitis C virus non-structural protein 5A and 5B have roles in the induction of autophagosomes. MicroRNAs regulate multiple physiological, pathological functions and autophagy through the modulation of gene expression. MicroRNA-122 is involved in HCV replication. In HBV-infected livers, the microRNA pathways related to cell death, DNA damage, recombination and signal transduction were activated. MicroRNA-122 effects multiple important factors which regulate the lipid and carbohydrate metabolisms in human non-alcoholic fatty liver disease. Oxidative stress and free oxygen radicals generation involved in alcoholic liver diseases development are regulated by microRNAs through different pathways. MicroRNAs control autophagy process and autophagy regulates the expression of microRNA-s. The exploration of their interactions contributes to understanding the development of liver diseases.

Viral infection, toxic injury, metabolic, autoimmun, storage disorders, in the case of ongoing presence of the etiological factors, could result in fibrotic remodelling in the liver. The process is complex, not fully understood in details; cells, cytokines, chemokines release, altered secretion of hepatokines, lipotoxicity, innate immun system, gut microbiom, metal ions and free radical reactions all have a role in it. Chronic liver disorders are often symptomless, diagnosed in the stage of fibrotic tissue accumulation, liver failure or hepatocellular carcinoma formation, when the prognosis is poor, treatment options are narrow. Noninvasive, properly sensitive and specific biomarkers are the targets of studies, with them the necessity of liver biopsies can be decreased, through the follow-up of processes, progression and treatment efficacy. Authors review the processes taking part in the progression of the most frequent chronic liver disorders, emphasizing the parameters of pro/antioxidant balance, and the necessity of a combined reliable biomarker.

In our review the effects of inflammation on the neuropeptide content of nerves and immune cells were compared. Inflamed tissue samples (human gastritis and animal models with experimental colitis and streptozotocin-induced diabetes mellitus) were examined. The number and contacts of neuropeptide-containing nerves and immune cells were studied using immunohistochemistry, confocal laser microscopy and electronmicroscopy. In inflammation, the number of substance P, vasoactive intestinal polypeptide and neuropeptide Y nerve fibres was increased significantly in parallel with the strongly increased number of immunocompetent cells (p less then 0.001). In inflammatory diseases, a large number of lymphocytes and mast cells were also positive for these neuropeptides. Very close morphological relationship between substance P and neuropeptide Y immunoreactive nerve fibres and immunocells could be demonstrated only in inflamed mucosa. Some of the substance P immunoreactive immunocells were also immunoreactive for tumor necrosis factor alpha and nuclear factor kappa B in the case of inflammation. The increased number of tumor necrosis factor alpha and nuclear factor kappa B immunoreactive immune cells correlated with the increased number of substance P-containing nerve fibres. Substance P, vasoactive intestinal polypeptide and neuropeptide Y released from nerve fibres and immunocells can play a role in inflammation. Our results suggest that using substance P antagonists or vasoactive intestinal polypeptide and neuropeptide Y peptides might be a novel therapeutic concept in the management of inflammation.

Within the past several decades, many incidences of mercury poisoning have been documented in several countries including Pakistan. Mercury has been ingested where it has been used to preserve crops, through the point and non-point source discharge into the surface water, and consequently entering the food chain. We conducted this scoping review of mercury and its health effects in Pakistan in order to raise the flag to a silent ongoing Minamata disease in the country. We conducted a systematic search of the available literature in Google Scholar, PubMed, and grey literature of unpublished theses and reports of various universities across the country. We found that in the northern Pakistan, suspended sediments were the major pathway of the riverine mercury transport. Sediments of Hunza and Gilgit River were found high in mercury concentrations. Gold mining leads to an increase in en toxic levels of mercury among the most vulnerable populations of the country. read more Other sources of mercury exposure included mercury in traditional medicines and cigarette products. Though no evidence was found for its presence in drinking water, its existence in the food chain and occupational exposure pose great threat to the humans as well as animals.Objectives We evaluated the spectrum of diseases accompanying congenital hypothyroidism (CH) in the United Arab Emirates and compared them with internationally studied patterns. Methods The presented retrospective cross-sectional study took place in two government tertiary care centres. In total, 204 patients with a confirmed diagnosis of CH and a minimum period of follow-up of 1 year were included. link2 Patients with Down syndrome, infants born at less then 35 weeks of gestation, and babies with TORCH (Toxoplasma gondii, Other viruses [HIV, measles, etc.], Rubella, Cytomegalovirus, and Herpes simplex) infections were subsequently excluded from the study. Results Of the subjects with CH, 39% had associated extrathyroidal anomalies (ETAs); among these, 25% had a single anomaly. A significant proportion of Arab males were affected by CH as compared to other ethnic groups. Dyshormonogenesis was the commonest aetiological cause (55%) of CH. Males with an ectopic lingual thyroid gland had significant ETAs as compared to females of the same cohort. The most common ETAs were congenital heart disease (16%), followed by urogenital tract anomalies (14%). Conclusions Detection of a high rate and variability of ETAs associated with CH necessitates the formulation of a structured screening programme including appropriate clinical, laboratory, and imaging tools to detect ETAs at an earlier stage.Objectives The mortality rate associated with community-acquired pneumonia is still considered high as it occupies a leading position among all infectious diseases. link3 The primary purpose of this study is to evaluate the implementation of the respiratory bacterial culture sampling in the clinical practice of the Russian Federation's therapeutic departments and its impact on inpatient care. Methods The study included 1,344 patients with community-acquired pneumonia. The analysis of the obtained data was performed using the statistical software package SPSS 23.0 (IBM SPSS Statistics). The description of quantitative indicators was carried out with an indication of the median (25; 75 percentile). Qualitative with an indication of the absolute and relative frequencies n (%). Results It was noted that a third of the sample did not pass through the first stage (bacterioscopy). We noticed the predominance of oropharyngeal flora in the results. The sputum collection was carried out on average 3 (1; 5) days after the start of hospitalization, while antibiotic therapy was prescribed to all patients on the first day, the results of the bacteriological study were ready on average 6 (4; 8th) calendar days after hospitalization, while in 20 (1.5%) cases, the patient was already discharged. Due to the inefficiency of the starting regimen, antimicrobial agents have changed in 84 (6.3%) patients and averaged 5.5 (4.0; 10.0) days from the start of hospitalization. Conclusions The violation of the technique and the time of sputum collection resulted in a reduction in the method's value.

Turner syndrome (TS) is a rare disorder affecting 1/2500 female newborn. Aortic dilatation (AD) and aortic dissection represent a major concern in TS. The aims of our study were to describe the aortic root growth, potential aortic dilatation (AD) risk factors and cardiovascular outcomes in a cohort of patients with TS.

Among 204 adult patients included, 197 were studied using a standardized 1.5 Tesla MRI protocol. AD was defined as an aortic diameter ≥20 mm/m2 at the Valsalva sinuses and/or at the ascending aorta, when indexed to body surface area.

At baseline, AD was present in 81/197 (41.1%) and 32/197 (16.2%) of patients, at the levels of Valsalva and ascending aorta, respectively. The aortic Valsalva diameter was larger in patients treated for thyroiditis (P < 0.001). Potential risk factors of AD were aging (P < 0.001) and the presence of bicuspid aortic valve (BAV) (P = 0.002). The hazard ratio (HR) of AD occurrence in the presence of BAV was 2.2 (95% CI 1.33-3.71). After a median follow-up period of 5.1 years (n = 143), AD was present in 58/143 (40.6%) and 25/143 (17.5%) of patients at the levels of Valsalva and ascending aorta, respectively. The median aortic growth of the Valsalva sinuses remained stable. At the ascending aorta, it increased by 0.14 ± 0.61 mm/year. Only one aortic-related death was observed.

AD is common in adult patients with TS. However, our results are rather reassuring, as the median aortic diameters remained stable after 5.1 years and few aortic events were observed.
