The Connection Between Selected Caspases Levels in Bronchoalveolar Lavage Fluid and Severity After Brain Injury.

Objective: The interaction between the brain and lungs has been the subject of many clinical reports, while the exact impact of brain injury on the physiology of the respiratory system is still subject to numerous experimental studies. The purpose of this study was to investigate the activation of selected caspases levels in bronchoalveolar lavage fluid (mini BALF) of patients after isolated brain injury and their correlation with the severity of the injury. Methods: The analysis was performed on patients who were admitted to the intensive care unit (ICU) for severe isolated brain injury from March 2018 to April 2020. All patients were intubated and mechanically ventilated. Mini BALF was collected within the first 6-8 h after trauma and on days 3 and 7 after admission. The concentrations of selected caspases were determined and correlated with the severity of brain injury evaluated by the Rotterdam CT Score, Glasgow Coma Score, and 28-day mortality. Results: Our results showed significantly elevated levels of selected caspases on days 3 and 7 after brain injury, and revealed apoptosis activation during the first 7 days after brain trauma. We found a significant different correlation between the elevation of selected caspases 3, 6, 8, and 9, and the Glasgow Coma Score, Rotterdam CT scale, and 28-day mortality. Conclusions: The increased levels of selected caspases in the mini BALF in our patients indicate an intensified activation of apoptosis in the lungs, which is related to brain injury itself via various apoptotic pathways and correlates with the severity of brain injury.

Why is it worth remembering the lung microbiome in ICU patients?

In recent years commensal microorganisms are not just "passive occupants", but important element of homeostasis. There are numerous reports documenting the composition and role of the gut, skin or vagina microbiome but the role of commensal orga-nisms living in the lungs is relatively unknown. Pulmonary microbiome impact on the immune response of the host organism and may indicate new therapeutic directions. Lung microbiome, by modulating the expression of innate immunity genes, causes an increase in the concentration of interleukin (IL)-5, IL-10, interferon γ and C-C motif chemokine ligand 11, affects the toll-like receptor-4-dependent response of pulmonary macrophages and modulate the production of antibacterial peptides contained in the mucus. It is documented that disorders of the lung microbiome contribute to asthma or chronic obstructive pulmonary disease. However it is known that pulmonary dysbiosis also occurs in critically ill patients. It is possible, therefore, that microbiota-targeted therapy may constitute the future therapeutic direction in ICU.

Usefulness of Cerebral Oximetry in TBI by NIRS.

Measurement of cerebral oximetry by near-infrared spectroscopy provides continuous and non-invasive information about the oxygen saturation of haemoglobin in the central nervous system. This is especially important in the case of patients with traumatic brain injuries. Monitoring of cerebral oximetry in these patients could allow for the diagnosis of inadequate cerebral oxygenation caused by disturbances in cerebral blood flow. It could enable identification of episodes of hypoxia and cerebral ischemia. Continuous bedside measurement could facilitate the rapid diagnosis of intracranial bleeding or cerebrovascular autoregulation disorders and accelerate the implementation of treatment. However, it should be remembered that the method of monitoring cerebral oximetry by means of near-infrared spectroscopy also has its numerous limitations, resulting mainly from its physical properties. This paper summarizes the usefulness of monitoring cerebral oximetry by near-infrared spectroscopy in patients with traumatic brain injury, taking into account the advantages and the disadvantages of this technique.

Intra-abdominal hypertension and hypoxic respiratory failure together predict adverse outcome - A sub-analysis of a prospective cohort.

PURPOSE: To assess whether the combination of intra-abdominal hypertension (IAH, intra-abdominal pressure ≥ 12 mmHg) and hypoxic respiratory failure (HRF, PaO2/FiO2 ratio < 300 mmHg) in patients receiving invasive ventilation is an independent risk factor for 90- and 28-day mortality as well as ICU- and ventilation-free days. METHODS: Mechanically ventilated patients who had blood gas analyses performed and intra-abdominal pressure measured, were included from a prospective cohort. Subgroups were defined by the absence (Group 1) or the presence of either IAH (Group 2) or HRF (Group 3) or both (Group 4). Mixed-effects regression analysis was performed. RESULTS: Ninety-day mortality increased from 16% (Group 1, n = 50) to 30% (Group 2, n = 20) and 27% (Group 3, n = 100) to 49% (Group 4, n = 142), log-rank test p < 0.001. The combination of IAH and HRF was associated with increased 90- and 28-day mortality as well as with fewer ICU- and ventilation-free days. The association with 90-day mortality was no longer present after adjustment for independent variables. However, the association with 28-day mortality, ICU- and ventilation-free days persisted after adjusting for independent variables. CONCLUSIONS: In our sub-analysis, the combination of IAH and HRF was not independently associated with 90-day mortality but independently increased the odds of 28-day mortality, and reduced the number of ICU- and ventilation-free days.

An analysis of anxiety and selected aspects of personality in women with ischemic heart disease according to P.T. Costa and R. R. McCrae theory - The role of psychosocial factors in ischemic heart disease.

INTRODUCTION: Risk factors for ischemic heart disease (IHD) are very numerous and not fully defined. In addition to classic risk factors, different factors are also distinguished, among them psychological aspects chich have rarely been subject to detailed analyses. OBJECTIVE: The aim of study was an analysis of the anxiety structure, including the five factors of personality: neuroticism (NEU), extraversion (EXT), openness (OPE), agreeableness (AGR) and conscientiousness (CON), in women with IHD. MATERIAL AND METHODS: The study involved 140 women aged 37-74 years with IHD confirmed by coronary angiography. Psychological examination was conducted using R.B. Cattell's IPAT Anxiety Scale and P.T. Costa and R.R. McCrae's NEO-FFI Personality Inventory. RESULTS: The results obtained from the IPAT Anxiety Scale showed that the study group of 140 women with IHD had the correct level of internal integrity (Q3- ). The dominant factor in the anxiety structure in 88.7% of subjects was neurotic tension (Q4+). A lack of sense of safety was indicated by 72.6% of subjects (L+), 69.3% experienced a strong tendency to self-blame and experience a sense of guilt (O + ), and over 51.6% of women with IHD expressed decreased emotional stability (C - ). The level of general anxiety was high (GA=7.3). The analysis of the five factors of personality revealed that the dominant factors in the structure of personality of women with IHD were CON in 69.3%, AGR in 46.7% and EXT in 45.2%. NEU and OPE were moderately significant factors. CONCLUSIONS: Women with IHD are characterised by a high level of anxiety, increased neurotic tension, decreased emotional stability, auto-aggression and a sense of danger and distrust. Women with IHD demonstrate a high level of factors, such as extraversion, agreeableness and conscientiousness.

PSYCHOLOGICAL RISK FACTORS FOR CARDIOVASCULAR DISEASES.

OBJECTIVE: Introduction: Cardiovascular diseases are one of the most important causes of the morbidity and mortality in the Polish and European population, accounting for nearly half of the causes of death. Prevention and treatment of cardiovascular diseases, especially in view of the predicted increase in mortality rate as a result of these diseases in the aging populations is crucial. The aim: To characterize selected psychological risk factors that predispose to the development of cardiovascular disease. RESULTS: Review and disscusion: Numerous scientific studies indicate the importance of mental and psychosocial factors in the prevention, treatment and rehabilitation patients with cardiovascular diseases. In this article the most important psychological risk factors, such as Type A and D personality, stress, depression and depressed mood, anxiety, social support and lifestyle are presented. CONCLUSION: Conclusions: Population-focused programs devoted to health promotion and informing the general public about the risk factors for cardiovascular diseases should mainly aim at improving people's lifestyle, in particular with regard to nutrition, smoking, alcohol consumption, physical activity and mental well-being.

[Old age can be joyful too].

All over world people live longer. In highly civilized societies the elderly people are half of the population. The old age crowns the whole life, it is the period when one enjoys the fruits of his labours. The man, when living on earth, completes a certain cycle which begins with the birth and is crowned with the old age. Each age is somehow beautiful but the extreme happiness is to go through the whole cycle. The old age is the specific beauty enriched with the past which had prepared it. Through their whole life one should be preparing to have successful, cheerful old age as it crowns air existence. The elderly like calmness, rest, silence and deadened sounds. Thanks to these traits they make every environment harmonious, calm and peaceful. They do it subconsciously thanks to their existence, exclusively through their own presence because these traits are the inherent part of their lives. The old age is God's grace given to man. That is why we may easily say that in their hand an old man holds their life's achievements that they will introduce to God one day.

Overt and Covert Anxiety as a Toxic Factor in Ischemic Heart Disease in Women: The Link Between Psychological Factors and Heart Disease.

BACKGROUND Long-term clinical observations have shown that anxiety disorders influence the etiopathogenesis of ischemic heart disease (IHD) in women. The aim of this study was to determine the characteristics of the structure of overt and covert anxiety, and to examine the impact of the severity of anxiety on five personality traits as described Costa and McCrae. MATERIAL AND METHODS The study involved 50 women aged 37 to 74 years, who were treated because of IHD that was confirmed by angiographic examination of the coronary vessels. Psychological studies were conducted using the IPAT Anxiety Scale (Cattell) and NEO-FFI Personality Inventory (Costa and McCrae). RESULTS From among the 50 women with IHD included in the study, 28 had higher overt anxiety scores than covert anxiety scores. Women with high overt anxiety were more emotionally changeable (C-), became impatient more easily, and expressed disappointment with life. They also worried about life problems more frequently. They had considerable suspiciousness (L+) and less trust towards the environment. They had a much stronger tendency to blame themselves (O+) and had intense internal, neurotic tension (Q4+). Women with high levels of overt anxiety had more neurotic traits (NEU), and lower openness to experience (OPE) scores. CONCLUSIONS Women with IHD were characterized by a high level of unease and anxiety. This may have resulted from lack of personality harmony, lack of personality integrity, or experienced value crises. Internal tension, auto-aggression, lowered emotional stability, and a sense of threat dominate the structure of unease and anxiety.
