Life after care: psychological adjustment to bereavement in family carers of people with dementia

BACKGROUND: Despite well-documented evidence of the psychological effects of caring for a relative with dementia, little is known about the bereavement experiences of family carers. The aim of this study was to explore the key psychological changes associated with carers' adjustment to bereavement and "life after care." METHODS: All carers taking part were recruited from a day care center, providing specialist services to people with dementia. We asked carers to describe the key changes associated with psychological adjustment to bereavement through semi-structured qualitative in-depth interviews. Strategies carers used to cope with and adapt to their new role were also explored. All data were thematically analysed. RESULTS: Thirty-one carers were interviewed. The most frequent emotional reactions to bereavement were feelings of loneliness, loss, void, sadness, anger, and relief. Most carers were able to adapt to their new role, and engaging in pleasant activities was the most frequent strategy used to cope with loss and "life after care." CONCLUSIONS: Feelings of loneliness and loss are amongst the key emotional reactions shaping carers' adjustment to bereavement. Most carers are able to adapt to loss; however, a minority experience increased psychological distress after the death of their loved one. A small percentage of carers continues caring for other dependants. Further research is required to identify how carers of people with dementia adapt to bereavement and how this increasing number of individuals can be best supported

A QUASI-EXPERIMENTAL PILOT STUDY OF THE EFFECTS OF A STRESS MANAGEMENT & HEALTH PROMOTION PROGRAM IN CHILDREN WITH ADHD

Objective: The purpose of the present study was to investigate the effects of a stress management and health promotion program on the primary and secondary symptoms of Attention Deficit/Hyperactivity Disorder (ADHD) as well as on other variables concerning the daily routine and lifestyle of children with ADHD. Furthermore, the effects on the levels of perceived stress and the quality of life of parents of children with ADHD were investigated.Method: The research type was quasi-experimental. Two groups were created (intervention and control group) with a total of 50 participants. Each participant in the intervention group engaged in 8 meetings over a period of two months. The intervention program included information relevant to stress and lifestyle (daily and eating habits, routine, exercise, sleep) as well as the application of cognitive behavioral therapy and stress management techniques.Results: The results are summarized as follows: significant decrease in anxiety and symptoms of ADHD, and improvement in sleep conditions, eating habits and frequency of physical exercise of the children were noted. Furthermore, a positive effect on perceived stress and quality of life of the parents of children with ADHD was observed.Conclusions: The results of the present study show that the stress management and health promotion program significantly improves both the symptoms of the disorder and the emotional state of children with ADHD, as well as their general lifestyle.  Article visualizations

Effect of intravenous clarithromycin in patients with sepsis, respiratory and multiple organ dysfunction syndrome: a randomized clinical trial.

Clarithromycin may act as immune-regulating treatment in sepsis and acute respiratory dysfunction syndrome. However, clinical evidence remains inconclusive. We aimed to evaluate whether clarithromycin improves 28-day mortality among patients with sepsis, respiratory and multiple organ dysfunction syndrome. We conducted a multicenter, randomized, clinical trial in patients with sepsis. Participants with ratio of partial oxygen pressure to fraction of inspired oxygen less than 200 and more than 3 SOFA points from systems other than the respiratory function were enrolled between December 2017 and September 2019. Patients were randomized to receive 1 gr of clarithromycin or placebo intravenously once daily for 4 consecutive days. The primary endpoint was 28-day all-cause mortality. Secondary outcomes were 90-day mortality; sepsis response (defined as at least 25% decrease in SOFA score by day 7); sepsis recurrence; and differences in peripheral blood cell populations and leukocyte transcriptomics. Fifty-five patients were allocated to each arm. By day 28, 27 (49.1%) patients in the clarithromycin and 25 (45.5%) in the placebo group died (risk difference 3.6% [95% confidence interval (CI) - 15.7 to 22.7]; P = 0.703, adjusted OR 1.03 [95%CI 0.35-3.06]; P = 0.959). There were no statistical differences in 90-day mortality and sepsis response. Clarithromycin was associated with lower incidence of sepsis recurrence (OR 0.21 [95%CI 0.06-0.68]; P = 0.012); significant increase in monocyte HLA-DR expression; expansion of non-classical monocytes; and upregulation of genes involved in cholesterol homeostasis. Serious and non-serious adverse events were equally distributed. Clarithromycin did not reduce mortality among patients with sepsis with respiratory and multiple organ dysfunction. Clarithromycin was associated with lower sepsis recurrence, possibly through a mechanism of immune restoration.

Global patient outcomes after elective surgery: prospective cohort study in 27 low-, middle- and high-income countries.

BACKGROUND: As global initiatives increase patient access to surgical treatments, there remains a need to understand the adverse effects of surgery and define appropriate levels of perioperative care. METHODS: We designed a prospective international 7-day cohort study of outcomes following elective adult inpatient surgery in 27 countries. The primary outcome was in-hospital complications. Secondary outcomes were death following a complication (failure to rescue) and death in hospital. Process measures were admission to critical care immediately after surgery or to treat a complication and duration of hospital stay. A single definition of critical care was used for all countries. RESULTS: A total of 474 hospitals in 19 high-, 7 middle- and 1 low-income country were included in the primary analysis. Data included 44 814 patients with a median hospital stay of 4 (range 2-7) days. A total of 7508 patients (16.8%) developed one or more postoperative complication and 207 died (0.5%). The overall mortality among patients who developed complications was 2.8%. Mortality following complications ranged from 2.4% for pulmonary embolism to 43.9% for cardiac arrest. A total of 4360 (9.7%) patients were admitted to a critical care unit as routine immediately after surgery, of whom 2198 (50.4%) developed a complication, with 105 (2.4%) deaths. A total of 1233 patients (16.4%) were admitted to a critical care unit to treat complications, with 119 (9.7%) deaths. Despite lower baseline risk, outcomes were similar in low- and middle-income compared with high-income countries. CONCLUSIONS: Poor patient outcomes are common after inpatient surgery. Global initiatives to increase access to surgical treatments should also address the need for safe perioperative care. STUDY REGISTRATION: ISRCTN5181700

Airborne particulate matter and human health: Toxicological assessment and importance of size and composition of particles for oxidative damage and carcinogenic mechanisms

Air pollution has been considered a hazard to human health. In the past decades, many studies highlighted the role of ambient airborne particulate matter (PM) as an important environmental pollutant for many different cardiopulmonary diseases and lung cancer. Numerous epidemiological studies in the past 30 years found a strong exposure-response relationship between PM for short-term effects (premature mortality, hospital admissions) and long-term or cumulative health effects (morbidity, lung cancer, cardiovascular and cardiopulmonary diseases, etc). Current research on airborne particle-induced health effects investigates the critical characteristics of particulate matter that determine their biological effects. Several independent groups of investigators have shown that the size of the airborne particles and their surface area determine the potential to elicit inflammatory injury, oxidative damage, and other biological effects. These effects are stronger for fine and ultrafine particles because they can penetrate deeper into the airways of the respiratory tract and can reach the alveoli in which 50% are retained in the lung parenchyma. Composition of the PM varies greatly and depends on many factors. The major components of PM are transition metals, ions (sulfate, nitrate), organic compound, quinoid stable radicals of carbonaceous material, minerals, reactive gases, and materials of biologic origin. Results from toxicological research have shown that PM have several mechanisms of adverse cellular effects, such as cytotoxicity through oxidative stress mechanisms, oxygen-free radical-generating activity, DNA oxidative damage, mutagenicity, and stimulation of proinflammatory factors. In this review, the results of the most recent epidemiological and toxicological studies are summarized. In general, the evaluation of most of these studies shows that the smaller the size of PM the higher the toxicity through mechanisms of oxidative stress and inflammation. Some studies showed that the extractable organic compounds (a variety of chemicals with mutagenic and cytotoxic properties) contribute to various mechanisms of cytotoxicity; in addition, the water-soluble faction (mainly transition metals with redox potential) play an important role in the initiation of oxidative DNA damage and membrane lipid peroxidation. Associations between chemical compositions and particle toxicity tend to be stronger for the fine and ultrafine PM size fractions. Vehicular exhaust particles are found to be most responsible for small-sized airborne PM air pollution in urban areas. With these aspects in mind, future research should aim at establishing a cleared picture of the cytotoxic and carcinogenic mechanisms of PM in the lungs, as well as mechanisms of formation during internal engine combustion processes and other sources of airborne fine particles of air pollution.

8-Hydroxy-2′ -deoxyguanosine (8-OHdG): A critical biomarker of oxidative stress and carcinogenesis

There is extensive experimental evidence that oxidative damage permanently occurs to lipids of cellular membranes, proteins, and DNA. In nuclear and mitochondrial DNA, 8-hydroxy-2′ -deoxyguanosine (8-OHdG) or 8-oxo-7,8-dihydro-2′ -deoxyguanosine (8-oxodG) is one of the predominant forms of free radical-induced oxidative lesions, and has therefore been widely used as a biomarker for oxidative stress and carcinogenesis. Studies showed that urinary 8-OHdG is a good biomarker for risk assessment of various cancers and degenerative diseases. The most widely used method of quantitative analysis is high-performance liquid chromatography (HPLC) with electrochemical detection (EC), gas chromatography-mass spectrometry (GC-MS), and HPLC tandem mass spectrometry. In order to resolve the methodological problems encountered in measuring quantitatively 8-OHdG, the European Standards Committee for Oxidative DNA Damage was set up in 1997 to resolve the artifactual oxidation problems during the procedures of isolation and purification of oxidative DNA products. The biomarker 8-OHdG or 8-oxodG has been a pivotal marker for measuring the effect of endogenous oxidative damage to DNA and as a factor of initiation and promotion of carcinogenesis. The biomarker has been used to estimate the DNA damage in humans after exposure to cancer-causing agents, such as tobacco smoke, asbestos fibers, heavy metals, and polycyclic aromatic hydrocarbons. In recent years, 8-OHdG has been used widely in many studies not only as a biomarker for the measurement of endogenous oxidative DNA damage but also as a risk factor for many diseases including cancer.

The ENPI Horizon 2020 Capacity Building/Mediterranean Environment Programme to de-pollute the Mediterranean by the year 2020 (ENPI H2020 CB/MEP)

The paper explains the content, structure, activities and contribution of the capacity building component of the Horizon 2020 Initiative, a major undertaking supported by the EU Neighbourhood policy instrument. The Mediterranean environment is one of the richest and at the same time most vulnerable in the world. A staggering 80% of its pollution comes from land based sources: municipal waste, urban waste and water, and industrial emissions. In 2006, the European Mediterranean Environment Ministers meeting in Cairo committed themselves to a targeted de-pollution of the Mediterranean Sea by 2020, known as the "Horizon 2020 Initiative". Within this framework, the Horizon 2020 Capacity Building/Mediterranean Environment Programme (H2020 CB/MEP) is one of its three operational components (the other two include the investments for pollution reduction infrastructures and pollution monitoring). It aims at supporting the implementation of the Horizon 2020 Initiative Road Map and Work Plan through a large number (~140) of capacity building and awareness raising activities, while strengthening institutions on environmental mainstreaming and H2020 priority areas. Environmental mainstreaming acts as an umbrella under which the three H2020 priorities are developed horizontally, cross cutting all capacity building activities so as to facilitate and create the enabling environment for the proper implementation, not only of the capacity building component of H2020 but also of the entire Initiative. It is expected that the H2020 CB/MEP will provide by the end of 2012 capacity building for an average of 200-300 persons per country, which means about 3500 individuals in the entire region. © 2012 Springer Science+Business Media B.V

Tobacco smoke: Involvement of reactive oxygen species and stable free radicals in mechanisms of oxidative damage, carcinogenesis and synergistic effects with other respirable particles

Tobacco smoke contains many toxic, carcinogenic and mutagenic chemicals, as well as stable and unstable free radicals and reactive oxygen species (ROS) in the particulate and the gas phase with the potential for biological oxidative damage. Epidemiological evidence established that smoking is one of the most important extrinsic factor of premature morbidity and mortality. The objective of this study was to investigate oxidative and carcinogenic mechanisms of tobacco and synergistic action with other respirable particles in the respiratory system of smokers. Electron Paramagnetic Resonance (EPR) and spin- trapping techniques were used to study stable free radicals in the cigarette tar, and unstable superoxide anion (O2.-) and hydroxyl (HO.) radicals in the smoke Results showed that the semiquinone radical system has the potential for redox recycling and oxidative action. Further, results proved that aqueous cigarette tar (ACT) solutions can generate adducts with DNA nucleobases, particularly the mutagenic 8-hydroxy-2'- deoxyguanosine (a biomarker for carcinogenesis). Also, we observed synergistic effects in the generation of HO., through the Fenton reaction, with environmental respirable particles (asbestos fibres, coal dust, etc.) and ambient particulate matter (PM), such as PM10, PM25 and diesel exhaust particles (DEP). The highest synergistic effects was observed with the asbestos fibres (freshly grounded), PM25 and DEP. Finally, we discuss results from our previous study of conventional cellulose acetate filters and "bio-filters" with hemoglobin impregnated activated carbon, which showed that these filters do not substantially alter the free radical content of smoke in the particulate and in the gaseous phase
