Oxidative stress-induced growth inhibitor 1 in alcohol-induced liver cirrhosis.

INTRODUCTION AND OBJECTIVE: Human oxidative stress-induced growth inhibitor 1 (OSGIN1) is a protein identified in 2001 which belongs to the OKL38 protein family. The aim of the study was to investigate the levels of this protein depending on the severity of alcohol-induced liver cirrhosis. MATERIAL AND METHODS: The study group consisted of 60 patients: 30 patients with cirrhosis in the P-Ch A and B stage and 30 in the P-Ch C stage. The control group consisted of 18 healthy individuals without liver diseases, who did not abuse alcohol. Oxidative stress induced growth inhibitor 1 (OSGIN1), fibroblast growth factor 1 (FGF1) and fibroblast growth factor 21 (FGF21) were determined in blood serum using enzyme-linked immunosorbent assay (ELISA) kits. All absorbance readings were conducted using an Epoch Microplate Spectrophotometer (BioTek Instrumentals, Inc., Winooski, VT, USA). OSGIN1, FGF1 and FGF21 concentrations were determined using Sandwich enzyme immunoassay kits (by Cloud Clone Corp., Katy, TX, USA). Statistica 13.3 (TIBCO Software, Inc.) was used for data analysis. RESULTS: The concentration of OSGIN1 was 0.028 ± 0.017 in the control group which increased with the advancement of liver cirrhosis (stage of Pugh-Child): 0.075 ± 0.098 in the P-Ch A + B group and 0.121 ± 0.134 in the P-Ch C stage. Multiple comparison tests confirmed statistically significant differences in OSGIN1 concentration between the control group and P-Ch C (p <0.02). Significant correlations were noted between OSGIN1 and FGF1 (r = 0.39; p = 0.004) and between OSGIN1 and FGF21 (r = 0.53; p <0.0001). CONCLUSIONS: The study revealed that the level of OSGIN1 increased significantly in the P-Ch C stage of liver cirrhosis. It is possible that OSGIN1 may be used for the non-invasive diagnosis of ALD, but its possible diagnostic value is still very uncertain.

Leukocyte cell-derived chemotaxin-2 and fibroblast growth factor 21 in alcohol-induced liver cirrhosis.

BACKGROUND: The importance of early diagnosis of alcoholic liver disease underscores the need to seek better and especially non-invasive diagnostic procedures. Leukocyte cell-derived chemotaxin-2 (LECT2) has been widely studied to determine its usefulness in monitoring the course of non-alcoholic fatty liver disease but not for alcoholic liver cirrhosis (ALC). AIM: To determine the concentration of LECT2 in the blood serum of patients in relation to progressive stages of ALC, its relation to fibroblast growth factor 1 (FGF-1) and FGF-21, and to examine the possible wider use of LECT2 in diagnosing ALC. METHODS: A retrospective case-control study was conducted with 69 ALC cases and 17 controls with no ALC. Subjects were recruited from the region of Lublin (eastern Poland). Liver cirrhosis was diagnosed based on clinical features, history of heavy alcohol consumption, laboratory tests, and abdominal ultrasonography. The degree of ALC was evaluated according to Pugh-Child criteria (the Pugh-Child score). Blood was drawn and, after centrifugation, serum was collected for analysis. LECT2, FGF-1, and FGF-21 were determined using enzyme-linked immunosorbent assay kits. RESULTS: The LECT2 Levels in the control group were 18.99 ± 5.36 ng/mL. In the study groups, they declined with the progression of cirrhosis to 11.06 ± 6.47 ng/mL in one group and to 8.06 ± 5.74 ng/mL in the other (P < 0.0001). Multiple comparison tests confirmed the statistically significant differences in LECT2 Levels between the control group and both test groups (P = 0.006 and P < 0.0001). FGF-21 Levels were 44.27 ± 64.19 pg/mL in the first test group, 45.4 ± 51.69 pg/mL in the second (P = 0.008), and 13.52 ± 7.51 pg/mL in the control group. The difference between the control group and the second test group was statistically significant (P = 0.007). CONCLUSION: We suggest that LECT2 may be a non-invasive diagnostic factor for alcohol-induced liver cirrhosis. The usefulness of LECT2 for non-invasive monitoring of alcohol-induced liver cirrhosis was indirectly confirmed by the multiple regression model developed on the basis of our statistical analysis.

Sir Gordon Morgan Holmes (1876-1965): one of the founders of modern neurology.

Sir Gordon Morgan Holmes (1876-1965) was one of the most important founders of modern neurology and a great teacher and scientist. He was the first scientist to challenge the theory of the unitary function of the cerebellum and described cerebellar disorders. Holmes together with Thomas Grainger Stewart (1877-1957) described 40 cases of the rebound phenomenon in cerebellar disease (Stewart-Holmes maneuver or Stewart-Holmes test). He also described the symptoms of inherited neurodegenerative spinocerebellar ataxia involving the olivary nucleus (Gordon-Holmes syndrome). Independently from the Australian neurologist William John Adie (1886-1935), he described the partial iridoplegia (Holmes-Adie pupil or Holmes-Adie syndrome). His teaching skills became clearly visible in Goulstonian and Croonian lectures dedicated to spinal cord injuries.

Concentrations of fetuin-A, osteoprotegerin and α-Klotho in patients with alcoholic liver cirrhosis.

The aim of the present study was to evaluate the concentrations of fetuin-A, osteoprotegerin (OPG) and α-Klotho protein in patients with alcoholic cirrhosis at different stages of the disease, and to demonstrate that fetuin-A, osteoprotegin and α-Klotho may be used as markers of the severity of cirrhosis. A total of 54 patients with alcoholic liver cirrhosis treated in various hospitals in the Lublin region of Poland were randomly enrolled. The control group consisted of 18 healthy individuals without liver disease, who did not drink alcohol. Serum levels of fetuin-A, OPG and α-Klotho were measured by ELISA kits. Levels of fetuin-A were significantly reduced in patients with alcoholic liver cirrhosis compared with the control group. OPG levels were higher in patients with alcoholic liver cirrhosis than in the controls, whereas the levels of α-Klotho were comparable in the cirrhosis and control groups. No statistically significant differences in the concentrations of fetuin-A, OPG and α-Klotho protein were demonstrated according to type of liver cirrhosis. The findings of the present study revealed a significant negative correlation between the level of α-Klotho protein and C-reactive protein in the patients with alcoholic liver cirrhosis. Concentrations of fetuin-A were lower, whereas those of OPG were higher, in the alcoholic liver cirrhosis group compared with the control group. Fetuin-A, OPG and α-Klotho may not be good indicators of liver cirrhosis severity. In conclusion, fetuin-A and OPG may be used in the diagnosis of liver cirrhosis.

Impact of beliefs about pain control on perceptions of illness in surgical patients.

OBJECTIVES: Adequacy of pain management in surgical patients is a major contributor to overall treatment outcomes and positive illness perceptions. However, it may be subjectively predetermined by a patient's beliefs about pain control. This study assesses the relationships between beliefs about pain control and perceptions of illness in thoracic surgical patients. MATERIALS AND METHOD: A total of 135 patients (72 women and 63 men; mean age 58.4±14.25y) were enrolled in the questionnaire study based on the Beliefs about Pain Control Questionnaire (BPCQ) by S. Skevington and the Multidimensional Essence of Disease and Illness Scale (MEDIS) by J. Sak. Analyses were conducted with use of the k-means clustering technique and one-way ANOVA. RESULTS: Applied classification revealed 3 different clusters of patients with regard to their beliefs about pain control: 1) weak, undifferentiated pain control; 2) intensified influence of chance pain control; 3) strong undifferentiated pain control. Significant differences in illness perceptions between clusters were disclosed in 3 MEDIS dimensions: self-realization constraints (F=4.70; p=0.01; 1 vs. 3), mental dysfunction (F=3.44, p=0.04; 1 vs. 3) and physical dysfunction (F=3.10, p=0.05; 1 vs 2). Patients in cluster 3 demonstrated a greater feeling of self-realization constraints and mental dysfunction than in cluster 1, whereas patients in cluster 2 perceived physical dysfunction as a greater distress than those in cluster 1. CONCLUSIONS: Beliefs about pain control significantly influence illness perceptions, and thus may affect the results of treatment in surgical patients. Psychological modelling of beliefs about pain control may offer a valuable way to improve overall clinical outcomes.

Physicians' religiosity and attitudes towards patients.

BACKGROUND: Many religions underline the value of merciful acts, especially the care of the sick. The aim of the survey was to verify the hypothesis that a higher religiosity correlates with a more desirable ethical attitude towards patients. METHOD: An anonymous questionnaire consisting of standardized tools: Scale of Attitudes towards the Patient (SAtP) (four dimensions: respect for autonomy, altruism, empathy and holistic approach to a patient), the Scale of Religious Attitudes (SReAt) evaluating the religiosity, and some questions related to the role of religious beliefs in respondents' professional lives. The research was carried out on a group of 528 Polish physicians, 324 of whom returned the questionnaire (return = 61%); 51% women, 49% men; average work experience: 17.03 years; 93% Catholics. RESULTS: Religiosity correlates positively with altruism (r=0.12; p<0.05), holistic approach (r=0.18; p<0.01) and empathy (r=0.20; p<0.01), but not with respect for autonomy. For the majority of physicians, religious faith is an important supportive factor, especially in making difficult decisions. Surgeons are less religious (M=5.32; SD=1.06) than non-surgeons (M=5.61; SD=0.93); (t= -2.59, p<0.05). CONCLUSION: Physicians' religiosity is an essential factor shaping their attitude towards patients. The majority of physicians declared that their religious faith influences their professional decisions, especially in difficult situations. The religiosity variable explains physicians' moral attitude better than the denomination (religious affiliation) variable. Physician-patient relation frameworks should take into account not only patients' but also physicians' cultural and religious beliefs.

[Is dehydration an ethical problem?]. / Czy odwodnienie moze byc problemem w kategoriach etycznych?

In the paper, issues connected with chronic dehydration were discussed from the point of view of medical ethics. Rudimentary definitions concerning the issues were mentioned. An attempt was made at analysing critically the views on chronic voluntary dehydration as a possible form of causing death. Some pathophysiological and psychopathological aspects were discussed. "The pyramid" of physician doubts were presented.
