Nurses' Views on Caring for Lonely Patients During the Pandemic: A Qualitative Study. Cureus 2024; 16:e57639. [PMID: 38707112 PMCID: PMC11070056 DOI: 10.7759/cureus.57639] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/03/2024] [Indexed: 05/07/2024] Open
Abstract
BACKGROUND The implementation of safety measures in hospitals due to the COVID-19 pandemic, including family visitation restrictions, forced the family to be absent during the patient's hospitalization. Nurses were confronted with new roles and responsibilities, as caring for lonely patients was a new phenomenon that emerged during the pandemic. PURPOSE The purpose of this study was to explore the nurses' views on caring for lonely patients during the COVID-19 pandemic. METHODS A qualitative research method based on an inductive content analysis approach was used. Data collection was carried out using semi-structured interviews. The sample consisted of 11 nurses who worked in COVID-19 wards and units. Content analysis was used to analyze the interview data. RESULTS The analysis of the data revealed three main themes: 1) caring for the patient and the family; 2) extending conventional care; and 3) developing supportive mechanisms for better care. Caring for lonely patients brought about changes in patients's management and care and significantly affected communication patterns as well as nurses' roles and responsibilities. Providing care beyond limits, supporting care through the utilization of new technologies, and transforming organization and care were mentioned as areas of challenge for nursing practice. Conclusions: Maintaining communication and supporting the family's involvement in patient care are considered to be equal to healing for the lonely patient. Reshaping working conditions and caring practices to meet the needs of the nurses, the patients, and their families during health crises may contribute positively to the provision of holistic care for patients and their families.

Factors Associated With Anxiety and Depression in Persons With Epilepsy (PWE). Cureus 2024; 16:e56401. [PMID: 38633953 PMCID: PMC11023706 DOI: 10.7759/cureus.56401] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/17/2024] [Indexed: 04/19/2024] Open
Abstract
INTRODUCTION Epilepsy is a common neurological disease that is associated with increased morbidity and mortality globally. Persons with epilepsy (PWE) experience a heavy emotional burden mainly due to social stigmatization and limited opportunities in life. The purpose of this study was to explore factors associated with anxiety and depression in PWE. MATERIAL AND METHODS In the present cross-sectional study, we enrolled 100 PWE who visited outpatient settings in a public hospital for scheduled follow-up. Data collection was carried out by the completion of the Hospital Anxiety and Depression Scale (HADS), which included participants' characteristics. The statistical significance level was p < 0.05. RESULTS Of the 100 participants, the majority were women (65%), below 50 years old (62%), and single (40%). In terms of mental comorbidity, 58% and 48% experienced anxiety and depression, respectively. A statistically significant association was observed between anxiety and age (p = 0.002). Furthermore, a statistically significant association was observed between depression and gender (p = 0.044), age (p = 0.001), marital status (p = 0.036), educational level (p = 0.003), job (p = 0.025), residency (p = 0.041), and whether they went out at night (p = 0.009). CONCLUSION Identifying factors associated with anxiety and depression is essential for PWE to receive appropriate support.

Characterization of multiple lysophosphatidic acid acyltransferases in the plant pathogen Xanthomonas campestris. FEBS J 2024; 291:705-721. [PMID: 37943159 DOI: 10.1111/febs.16996] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Revised: 10/09/2023] [Accepted: 10/20/2023] [Indexed: 11/10/2023]
Abstract
Phosphatidic acid (PA) is the precursor of most phospholipids like phosphatidylethanolamine, phosphatidylglycerol, and cardiolipin. In bacteria, its biosynthesis begins with the acylation of glycerol-3-phosphate to lysophosphatidic acid (LPA), which is further acylated to PA by the PlsC enzyme. Some bacteria, like the plant pathogen Xanthomonas campestris, use a similar pathway to acylate lysophosphatidylcholine to phosphatidylcholine (PC). Previous studies assigned two acyltransferases to PC formation. Here, we set out to study their activity and found a second much more prominent function of these enzymes in LPA to PA conversion. This PlsC-like activity was supported by the functional complementation of a temperature-sensitive plsC-deficient Escherichia coli strain. Biocomputational analysis revealed two further PlsC homologs in X. campestris. The cellular levels of the four PlsC-like proteins varied with respect to growth phase and growth temperature. To address the question whether these enzymes have redundant or specific functions, we purified two recombinant, detergent-solubilized enzymes in their active form, which enabled the first direct biochemical comparison of PlsC isoenzymes from the same organism. Overlapping but not identical acyl acceptor and acyl donor preferences suggest redundant and specialized functions of the X. campestris PlsC enzymes. The altered fatty acid composition in plsC mutant strains further supports the functional differentiation of these enzymes.

Investigation of Perception of Quality of Life and Psychological Burden of Patients Undergoing Hemodialysis-Quality of Life of Hemodialysis Patients. NURSING REPORTS 2023; 13:1331-1341. [PMID: 37755355 PMCID: PMC10535584 DOI: 10.3390/nursrep13030112] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Revised: 09/11/2023] [Accepted: 09/15/2023] [Indexed: 09/28/2023] Open
Abstract
Chronic kidney disease (CKD) has a significant impact on the life of patients undergoing chronic periodic hemodialysis. It negatively affects their social, economic and family status, and particularly their psychological well-being. The aim of this study was to investigate the perception of the quality of life (QoL) and psychological burden of patients undergoing hemodialysis. A cross-sectional study was conducted with 63 patients. Τhe majority were men (63.5%), and the mean age of the patients was 66.7 years (±12.9) with 61.9% aged 65-89 years. Data collection was performed in 2021 using the Hospital Anxiety and Depression Scale (HADS) and the Kidney Disease and Quality of Life-Short Form (KDQOL-SF™) research tools, and their relationships were assessed using parametric and non-parametric methods. Moderate to mild levels of Anxiety and Depression were found. Physical and Mental Composite Scores were mild to moderate, with the Mental Composite Score being significantly higher (p < 0.05). Anxiety and Depression were significantly correlated with lower QoL (p < 0.05), while a higher educational level was correlated with lower Depression Symptom Levels and higher QoL for Disease Symptoms, Disease Effects, Physical Functioning, Vitality and Overall Health (p < 0.05). A higher number of years of hemodialysis was correlated with lower levels of Anxiety and higher levels of Quality of Sleep (p < 0.05). Ease of Access to the Hemodialysis Unit was correlated with lower levels of Social Support (p < 0.05). The highest Mental Composite Scores were also correlated with a higher level of education, with patients living in urban areas, and with a higher monthly income (p < 0.05). Patients with moderate or severe levels of Anxiety and Depression had a lower QoL in the Physical and Mental Composite Scores, indicating their dependence on the appropriate medical, nursing and social environment in order to attain higher levels of well-being, leading to the improvement of patients' health. This study was not registered.

Surgical Aortic Valve Replacement in Patients Aged 50 to 70 Years: Mechanical or Bioprosthetic Valve? A Systematic Review. Healthcare (Basel) 2023; 11:1771. [PMID: 37372888 DOI: 10.3390/healthcare11121771] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Revised: 05/26/2023] [Accepted: 06/12/2023] [Indexed: 06/29/2023] Open
Abstract
Although transcatheter aortic valve implantation has emerged as a very attractive treatment option for severe aortic valve disease, surgical aortic valve replacement (SAVR) is still considered the standard-of-care, particularly in younger patients. However, selecting the appropriate type of valve prosthesis for this patient population can pose challenges. The aim of this systematic review was to investigate morbidity and mortality in patients aged 50-70 years who have undergone a first-time SAVR, and to define and compare the outcomes of mechanical valve (MV) and biological valve (BV) prosthesis. A systematic search was conducted to investigate the clinical outcomes of MVs and BVs in patients aged 50-70 years following the PRISMA guidelines. A total of 16,111 patients were included in the studies with an average follow-up of 10 years. A total of 16 studies were selected, 12 of which included propensity-score-matching (PMS) analysis and 4 of which obtained results via multivariate analysis. The vast majority (13 studies) showed no greater survival benefit in either MVs and BVs, while three studies showed an advantage of MVs over BVs. Regarding complications, bleeding was the most common adverse event in patients undergoing MV replacement, while for patients receiving BV prosthesis, it was structural valve deterioration and reoperation. Although the data suggest that the BV option could be a safe option in patients younger than 70 years, more studies with contemporary data are needed to draw firm conclusions on the risks and benefits of BV or MV in SAVR. Physicians should individualize the surgical plan based on patient characteristics.

Abstract
INTRODUCTION Percutaneous coronary intervention (PCI) is a non-surgical invasive procedure to treat coronary artery occlusion. The quality of life (QoL) is a way to measure the impact of illness and additionally its treatments to traditional measures of clinical outcomes. PURPOSE The aim of the present study was to explore the levels of QoL pre-PCI, 6 and 12 months after PCI, as well as the factors associated with the QoL pre-PCI. METHODS In the present study, 100 patients undergoing PCI were enrolled. Data were collected through the completion of the SF-36 Health Survey (SF-36), which included participants' characteristics. The statistical significance level was p < 0.05. RESULTS Patients had moderate levels of QoL at baseline, with a median general health score of 45 (IQR: 30-65). A gradual statistically significant increase in scores was observed in all subcategories of the patients' QoL at 6 and 12 months after PCI (p < 0.001). A greater increase in scores was observed in physical functioning, physical role, emotional role and social functionality. In terms of the pre-PCI phase, it was found that physical functionality was statistically significantly associated with educational level (p = 0.005), occupation (p = 0.026) and whether the patients had children (p = 0.041). The physical and emotional role was significantly associated with gender (p = 0.046 and p = 0.040) and educational level (p = 0.030 and p = 0.001). Energy-fatigue was significantly associated with gender (p = 0.001), age (p = 0.028), marital status (p = 0.001), educational level (p = 0.001), whether the patients had children (p= 0.012) and other diseases (p = 0.001). Emotional well-being was significantly associated with family history of coronary artery disease (p = 0.011) and the frequency of physical exercise (p = 0.001). Social functioning was significantly associated with gender (p = 0.033), marital status (p = 0.034) and educational level (p = 0.002). Pain was not found to be significantly associated with patients' demographics. General health was significantly associated with gender (p = 0.003), age (p = 0.043), educational level (p = 0.001), other diseases (p = 0.005) and the frequency of physical exercise (p = 0.001). CONCLUSION Information about the QoL of PCI and its determinants is important to define an effective and comprehensive care plan.

Abstract
Introduction. Patients suffering from pressure ulcers experience low quality of life, in every dimension of daily living.
Aim. The aim of this systematic review was to investigate the impact of pressure ulcers on the patients’ quality of life involving mental/emotional, spiritual, physical, social, cognitive dimensions, and pain.
Methods. A systematic literature search of published articles in the English language during the past 15 years was conducted. Articles were identified in the electronic databases of Google Scholar, PubMed, and PsycINFO using the keywords: pressure ulcers, quality of life, emotional dimension, social dimension, physical dimension. The inclusion criteria were: articles relevant to the study topic, written in English, and published between 2004 and 2019. Articles that were secondary studies, such as reviews and meta-analyses, case studies, and articles written in a language other than English, were excluded from the study. The PRISMA method was applied.
Results. Fourteen studies were included in this systematic review. Eight were quantitative studies (six cross-sectional, one longitudinal, one multicenter cohort, and one pilot study) and six qualitative (one was based on grounded theory, one pilot study, one case study of mixed methods, one phenomenological study, and one comparative study). The emerging themes were related to the mental/emotional, spiritual, physical, social, cognitive dimensions, and pain.
Conclusions. Pressure ulcers have a negative impact on the patients’ quality of life, especially at a psychological level. Patients’ life is severely affected as they are fully dependent on their supportive environment and health services.

Abstract
Accretion disks around compact objects are expected to enter an unstable phase at high luminosity1. One instability may occur when the radiation pressure generated by accretion modifies the disk viscosity, resulting in the cyclic depletion and refilling of the inner disk on short timescales2. Such a scenario, however, has only been quantitatively verified for a single stellar-mass black hole3-5. Although there are hints of these cycles in a few isolated cases6-10, their apparent absence in the variable emission of most bright accreting neutron stars and black holes has been a continuing puzzle11. Here we report the presence of the same multiwavelength instability around an accreting neutron star. Moreover, we show that the variability across the electromagnetic spectrum-from radio to X-ray-of both black holes and neutron stars at high accretion rates can be explained consistently if the accretion disks are unstable, producing relativistic ejections during transitions that deplete or refill the inner disk. Such a new association allows us to identify the main physical components responsible for the fast multiwavelength variability of highly accreting compact objects.

Abstract
Pressure ulcers have high prevalence in patients and can be prevented with proper nursing interventions. The aim of this study was to evaluate nurses' knowledge about prevention and treatment of pressure ulcers. The present study was conducted with 111 nurses working in a General hospital in Greece. In this study, nurses had adequate knowledge about prevention and treatment of pressure ulcers. Respondents answered correctly in questions about staging of pressure ulcers (98.2%, 98.2%, 99.1%, 97.3%, 93.7%), the role of changing position in prevention of pressure ulcer (97.3%), the use of foam mattress (85.6%) and stretched sheets (92.8%), the use of antiseptic solution (95.5%, 85.6%), and interventions to reduce pressure on patients' heels (88.3%). A number of participants had adequate level of knowledge in the questions about the role of diet in healing of pressure ulcers (71.2%), products or devices for prevention or treatment of pressure ulcers (61.3%, 36.9%), healing of pressure ulcers (58.6%, 46.8%), prevention of bone pressure ulcers (31.5%), cleaning of a pressure ulcer (52.3%), and the role of low blood pressure as a risk factor for pressure ulcer (55.9%). However, the development of educational programs can help nurses to improve their knowledge about prevention and treatment of pressure ulcers.

A persistent ultraviolet outflow from an accreting neutron star binary transient. Nature 2022; 603:52-57.

Abstract
All disc-accreting astrophysical objects produce powerful disc winds. In compact binaries containing neutron stars or black holes, accretion often takes place during violent outbursts. The main disc wind signatures during these eruptions are blue-shifted X-ray absorption lines, which are preferentially seen in disc-dominated 'soft states'1,2. By contrast, optical wind-formed lines have recently been detected in 'hard states', when a hot corona dominates the luminosity3. The relationship between these signatures is unknown, and no erupting system has as yet revealed wind-formed lines between the X-ray and optical bands, despite the many strong resonance transitions in this ultraviolet (UV) region4. Here we report that the transient neutron star binary Swift J1858.6-0814 exhibits wind-formed, blue-shifted absorption lines associated with C IV, N V and He II in time-resolved UV spectroscopy during a luminous hard state, which we interpret as a warm, moderately ionized outflow component in this state. Simultaneously observed optical lines also display transient blue-shifted absorption. Decomposing the UV data into constant and variable components, the blue-shifted absorption is associated with the former. This implies that the outflow is not associated with the luminous flares in the data. The joint presence of UV and optical wind features reveals a multi-phase and/or spatially stratified evaporative outflow from the outer disc5. This type of persistent mass loss across all accretion states has been predicted by radiation-hydrodynamic simulations6 and helps to explain the shorter-than-expected duration of outbursts7.

Abstract
Introduction: Insomnia is the most common sleep disorder among patients on hemodialysis and has a strong relation with fatigue, depression, low immune system, increased risk of cardiovascular problems, and low quality of life. The aim of this study was to explore the factors associated with insomnia in patients undergoing hemodialysis. Methods: In this cross-sectional study, 100 patients on hemodialysis (75 males and 25 females) from a hemodialysis center in Greece were included. Insomnia was assessed via the "Athens Insomnia Scale (AIS)" and a questionnaire about demographic and clinical characteristics. The Kruskal-Wallis, Mann-Whitney tests, and Spearman's rho criterion were used to evaluate the association between insomnia score and patients' characteristics. Multiple linear regression was performed to assess the effect of characteristics on patients' insomnia. Results: Statistically significantly high levels of insomnia were found in patients over the age of 60 years (p = 0.002), in divorced/widowed patients (p = 0.007), in patients who had comorbid diseases (p = 0.001), in patients who felt tired after hemodialysis (p = 0.001), in those who had continuous fatigue (p = 0.001) and change in body image (p = 0.003), in those who often had itching (p = 0.007) and stiffness in joints (p = 0.001) and in patients who had limitations in the clothes they could wear (p = 0.001). Conclusions: The findings of this study showed that insomnia had a strong association with increased age of patients, comorbidities, fatigue, change in body appearance, pruritus, and limitation in clothes they could wear. Therefore, there is a necessity for early assessment of sleep quality and effective treatment of sleep disorders in hemodialysis patients in order to reduce morbidity and mortality and improve the quality of their life.

Abstract
Background Patients undergoing hemodialysis face multiple problems such as difficulties in performing daily activities, low functional capacity, non-adherence to the hemodialysis regimen, and depressive symptoms that lead to poor health outcomes. The present study aimed to assess the levels of depression, adherence, and functionality in patients undergoing hemodialysis, as well as the association between the above variables. Materials and methods In this cross-sectional study, 100 patients undergoing hemodialysis from a private hospital in Athens participated. Data were collected via the Zung Self-Rating Depression Scale, the Barthel Scale/Index, and the Greek Simplified Medication Adherence Questionnaire-Hemodialysis for the evaluation of patients’ depression, functionality, and adherence to hemodialysis regimen, respectively. In addition, sociodemographic and clinical characteristics were recorded. The study was conducted during the period of December 2020 to February 2021. IBM SPSS Statistics for Windows, Version 25.0 (Released 2017. IBM Corp., Armonk, New York) was used for the statistical analysis of the data. The statistical significance level was set up at 0.05. Results Of the patients, 50% scored < 38 (possible range 20-80) in the scale pof depression, and 25% of patients scored < 34. Regarding adherence, the median value was 7 (IQR: 7-7) while 77% scored 7 (possible range of 0-8). Regarding functionality, mild dependence (score 91-99) was referred by 77% of the participants, moderate dependence (score 61-90) by 17%, and severe dependence (score 21-60) was referred by 6% of the patients. A statistically significant negative association emerged between depression and functionality (r= -0.342, p=0.001) while no significant association arised between depression and adherence (r= 0.021,p=0.836) as well as between adherence and functionality (r = 0.078, p = 0.439). Statistical significantly higher scores of depression were seen in women (β = 3.65, p = 0.001) and elderly >70 years old (β = 3.51, CI=0.09-6.93, p = 0.044). Statistically significantly lower functionality were referred by patients >70 years old (β = -13.58, CI: -21.68-5.49, p = 0.001) and by patients with high depression score (β= -0.62, 95% CI: -1.06-0.20, p = 0.005). Conclusion Patients experienced moderate to low levels of depression and high levels of adherence and functionality. The higher the functionality scores, the lower the depression scores. Demographic characteristics, such as age and gender, seem to be significant predictors of depression and functionality.

Abstract
Anxiety and depression have high levels in caregivers of patients on hemodialysis and are strongly associated with demographic factors. The aim of this study was to evaluate the factors affecting anxiety and depression in caregivers of hemodialysis patients. Four hundred and fourteen (414) caregivers (98 males and 316 females) participated in this study. Depression and anxiety were assessed by the Hospital Anxiety and Depression Scale (HADS), the State-Trait Anxiety Inventory (STAI), and the Beck Depression Inventory (BDI). Multinomial logistic regression was performed to estimate the factors being independently associated with anxiety and depression levels. Multiple linear regression was performed to estimate the factors being independently associated with Beck Depression Inventory and State-Trait Anxiety Inventory. From a total of 414 participants, 125 (30.2%) had depression and 215 (52%) had anxiety. The median age of respondents was 54.34 (43.9-66.28) years, with half of the sample's age ranging from 43.9 to 66.28 (IQR). Depression and anxiety were significantly associated with parents or siblings, low level of education, increased caregivers' age, retirement, poor financial condition, having children, and comorbidities. In this study, a significant proportion of caregivers were found to have high levels of depression and anxiety. Thus, a formal screening can contribute to early diagnosis and treatment of depression and anxiety in caregivers of patients on hemodialysis.

Abstract
Introduction: Diabetic foot ulcer (DFU) is a common complication of diabetes mellitus associated with increased morbidity and mortality and diminished quality of life (QoL). This study aimed to explore the effect of gender differences on QoL and adherence to self-care activities.
Methods: In this cross-sectional study, we enrolled 135 male and 135 female patients with DFU. Data was collected using the Short Form Health Survey (SF-36) and a questionnaire that measured self-care activities (Diet, Exercise, Blood Examination, and Foot Check). Data analysis was performed using SPSS version 20.
Results: In terms of QoL, male participants had moderate to high levels in the categories of energy/fatigue, emotional well-being, social functioning, and bodily pain, whereas they had low levels in physical functioning, physical role, and emotional role. Female patients had moderate QoL in the categories of energy/fatigue and social functioning, whereas they had low QoL in physical functioning, physical role, emotional role, emotional well-being, and bodily pain. Finally, regarding general health, male participants had moderate QoL and females had moderate to low QoL. Both males and females had low adherence to exercise and high in blood-examinations. For both genders, adherence to exercise had a statistically significant association with all sub-categories of QoL apart from those of role (physical and emotional).
Conclusion: It is essential for health care professionals to provide gender-specific approaches in treatment of ulceration.

Recombinant and endogenous ways to produce methylated phospholipids in Escherichia coli. Appl Microbiol Biotechnol 2021; 105:8837-8851. [PMID: 34709431 PMCID: PMC8590670 DOI: 10.1007/s00253-021-11654-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Revised: 10/15/2021] [Accepted: 10/19/2021] [Indexed: 10/31/2022]
Abstract
Escherichia coli is the daily workhorse in molecular biology research labs and an important platform microorganism in white biotechnology. Its cytoplasmic membrane is primarily composed of the phospholipids phosphatidylethanolamine (PE), phosphatidylglycerol (PG), and cardiolipin (CL). As in most other bacteria, the typical eukaryotic phosphatidylcholine (PC) is not a regular component of the E. coli membrane. PC is known to act as a substrate in various metabolic or catabolic reactions, to affect protein folding and membrane insertion, and to activate proteins that originate from eukaryotic environments. Options to manipulate the E. coli membrane to include non-native lipids such as PC might make it an even more powerful and versatile tool for biotechnology and protein biochemistry. This article outlines different strategies how E. coli can be engineered to produce PC and other methylated PE derivatives. Several of these approaches rely on the ectopic expression of genes from natural PC-producing organisms. These include PC synthases, lysolipid acyltransferases, and several phospholipid N-methyltransferases with diverse substrate and product preferences. In addition, we show that E. coli has the capacity to produce PC by its own enzyme repertoire provided that appropriate precursors are supplied. Screening of the E. coli Keio knockout collection revealed the lysophospholipid transporter LplT to be responsible for the uptake of lyso-PC, which is then further acylated to PC by the acyltransferase-acyl carrier protein synthetase Aas. Overall, our study shows that the membrane composition of the most routinely used model bacterium can readily be tailored on demand.Key points• Escherichia coli can be engineered to produce non-native methylated PE derivatives.• These lipids can be produced by foreign and endogenous proteins.• Modification of E. coli membrane offers potential for biotechnology and research.

[PMID: 34444262 PMCID: PMC8393572 DOI: 10.3390/ijerph18168512] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 06/18/2021] [Revised: 08/05/2021] [Accepted: 08/07/2021] [Indexed: 12/30/2022]
Abstract
Introduction: Living with a permanent colostomy brings severe changes in patients’ lives. The general health status as well as the personal, social and professional life of patients are significantly affected. Aim: The aim of the present study was to investigate the lived experience of patients undergoing permanent colostomy. Material and Methods: A qualitative research design based on interpretive phenomenology was carried out. Semi-structured interviews were conducted as the data collection method to obtain in-depth information regarding the research topic. The study sample consisted of eight (8) patients who had undergone a permanent colostomy. The data analysis was performed by the method of content analysis. Results: From the analysis of the data, three main themes emerged, namely: (A) Experiencing a traumatic event; (B) Living a new reality; (C) Efforts to improve quality of life. Five subthemes were formulated which were encompassed within the respective main themes accordingly. Conclusion: Patients with permanent colostomy face significant life changes that are experienced in a traumatic way. Issues such as autonomy, family and organizational support, self-management and empowerment can significantly improve the patients’ quality of life. Further research, regarding caregivers’ experience, improved community nursing care as well as nurses’ views on the needs of colostomy patients and their families, is suggested.

Factors Affecting State and Trait Anxiety of Relatives of Hospitalized Patients. J Caring Sci 2021; 10:9-14. [PMID: 33816379 PMCID: PMC8008228 DOI: 10.34172/jcs.2021.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2020] [Accepted: 07/08/2020] [Indexed: 11/13/2022] Open
Abstract
Introduction: Hospitalization is a stressful event for both patients and relatives. The aim of the study was to explorefactors affecting state and trait anxiety of relatives of hospitalized patients. Methods: In this cross-sectional study, was enrolled a convenience sample of 222 relatives of hospitalized patients in a public hospital in Athens, Greece. Data were collected by the completion of State-Trait Anxiety Inventory (STAI) which also included participants’ characteristics. Data were analyzed using SPSS version 25, while the statistical significance level was P < 0.05. Results: Of the 222 relatives, 72 were men and 150 women. The average state and trait anxiety score was 45.6 and 42, respectively, within the possible range of scores (20-80) thus indicating moderate levels of anxiety. Moreover, state and trait anxiety was statistically significantly associated with gender, degree of information of patient’s health, whether they had readjusted family responsibilities, whether they had financial worries, whether they experienced uncertainty about future and finally whether they were anxious about their ability to respond to patients care. Conclusion: Factors associated with relatives’ anxiety were gender, information regarding patient’s health, family responsibilities, financial worries, uncertainty and anxiety to respond to patients’ care. These factors need to be evaluated when planning psychological intervention to alleviate this emotional burden.

Abstract
Introduction: Percutaneous coronary intervention (PCI) is a nonsurgical procedure used in the treatment of coronary heart disease. Purpose: The purpose of this study was to validate a scale created in order to assess the importance and fulfillment of information needs in patients after PCI. Methods: A 10-item scale was created by the researchers to explore the level of information needs and the level of fulfillment of these needs. The total scores have a possible range of 10 to 40 with higher scores indicating higher importance and fulfillment. The validation of the questionnaire included face and content validity, construct validity, internal consistency, repeatability, and discriminant validity. Results: Forty patients contributed to this validation. Mean and median scores for each question separately and also overall scores suggest that patients consider the need to be informed very important and that it was fulfilled to a very high degree (mean scores 39.5 and 39.3, respectively). All questions were found to be significantly correlated with the overall scores (rho > 0.3) meaning strong construct validity. Cronbach’s α coefficients were high (>0.7) indicating great consistency. Both total scores had great repeatability, which suggests a high degree of reliability of the participants' responses (ICCs > 0.8). Regarding discriminant validity, a statistically significant association was observed only between marital status and the degree of fulfillment of the need to be informed (p = 0.036). More specifically, divorced or widowed patients had a lower degree of fulfillment than married patients (mean 38.6 vs. 39.6). Conclusion: It is a reliable instrument that will help clinicians who are at close contact with patients after PCI to gain a better understanding of their needs.

Abstract
Introduction Burns in children are painful, can be fatal, and involve a significant risk of complications, along with physical and psychological consequences. This study aimed to investigate the incidence of burns in children, for six months, and the most common causative factors, along with the existing correlations between demographic data and the characteristics of burn injuries. Methods The study was descriptive and prospective, and the sample consisted of minors up to 14 years old with burns in any areas of the body. The research was carried out in the Attica pediatric hospitals’ selected departments for six months (from July to December 2018). Sources for completing the created database were the patients, their guardians, and their medical-nursing documentation and records. Results The cumulative six-month incidence rate of childhood burn disease was 4.9%. The most affected age group appeared to be younger than two years (60%), while liquid heat appeared to be the primary form of the burn factor (76%). The average duration of hospitalization for children with a deep partial-thickness to a total-thickness burn degree was 16.5 days. The correlations that emerged related to the extent of the burn were directly related to the accident’s site, and patients with an increased likelihood of future additional surgeries had an increased mean total body surface area that was burned. Conclusion Continuous surveillance and removal of hazardous materials from the home environment is of utmost need. Early education/understanding of correct behaviors and proper attention to outdoor activities or excursions can significantly reduce burns. Training courses on burn prevention for parents are needed, as the best form of treatment is prevention.

Abstract
Background Lymphedema is a chronic condition caused by a failure in the lymphatic system that most commonly occurs in the limbs. Complete decongestive therapy (CDT) is the gold standard for lymphedema management. Objective To evaluate the effectiveness and safety of complete decongestive therapy (CDT) of phase I in the Greek population with lymphedema. Methods The patients’ demographic and clinical characteristics were recorded. CDT was implemented in all patients for 20 sessions in a four-week treatment period. The edema’s (excess volume (EV) and percent of excess volume (PEV)) measurements were carried out four times in the treatment period, whereas the percent reduction of excess volume (PREV) was calculated at the end of phase I. Moreover, we recorded every infection, trauma of skin, and pain of limb during the treatment. Results One-hundred five patients with lymphedema were enrolled in the present study, of whom 31.4% had upper limb lymphedema and 68.6% had lower limb lymphedema. All patients with upper limb lymphedema had a secondary type while the corresponding proportion of patients with lower limb lymphedema was 58.3%. A significant reduction (p<0.001) between the pre-treatment and post-treatment values of EV and PEV was found for both upper and lower limb lymphedema. For patients with upper limb lymphedema, the average PREV was 66.5% (interquartile range, 57.3%-80.6%), whereas for patients with lower limb lymphedema, a 71.5% (interquartile range, 64.5%-80.7%) median value was measured. No side effects from the treatment were recorded during CDT. Conclusion The proper treatment of the CDT phase I ensures safety and a great reduction in edema in patients with lymphedema that predispose the success of phase II of CDT.

Abstract
Objective The aim of this research was to compare the effectiveness of two mattresses used in intensive care unit (ICU) high-risk patients in terms of pressure ulcers (PUs) prevention and healing. Materials and Methods The studied sample consisted of 70 consecutive patients aged 18 to 65 years hospitalized in two ICUs of a general hospital in Athens, Greece. Virtuoso Mattress System (LINET, Slaný, Czech Republic) was used in 35 patients, and standard memory foam mattress was used in the rest of participants. Patients were firstly assessed on enrollment and then every 72 hours in order to record the appearance or not of PUs, location of PUs, and stage of PUs, with the maximum follow-up not exceeding the 21 days. A number of clinical and biochemical factors, medical treatment, and vital signs were also recorded at each time point. Results Of the 70 patients, 40 (57.1%) were men, and the mean ± standard deviation age of the sample was 46.1 ± 14.5 years. The most common area of PUs was the buttocks (34.3%) followed by the shoulders (22.3%), with no statistically significant difference detected between the two groups. Moreover, the proportion of patients having PUs at stage 2 or higher was 23.8% on the third day after admission and 61.1% on the sixth day, with no difference detected between the two groups. Cox proportional hazard model revealed that the Virtuoso mattress was associated with almost 56% lower risk of developing PUs compared with standard foam mattress (HR [95% CI]: 0.44 [0.20-0.93]). The percentage of patients healed using the Virtuoso mattress was significantly lower compared with the standard foam mattress at all time points, with the results reaching statistical significance only on the 12th day after admission (7.7% vs. 66.7%; p < 0.05). Conclusions The Virtuoso mattress seems to be more effective compared with standard foam mattresses in the prevention of PUs, whereas the standard foam mattresses are more effective in PU healing process.

Abstract
Diabetic foot ulcer (DFU) exerts a heavy physical and emotional burden on patients with diabetes mellitus. The purpose of the present study was to explore the impact of anxiety and perceived social support on depression of DFU patients well as patients' characteristics associated with depression. The sample of the study consisted of 180 DFU patients. Data collected by the completion of "Self-rating Depression/Anxiety Scale- Zung" (SDS/SAS) and the Multidimensional Scale of Perceived Social Support (MSPSS). Patients had moderate levels of anxiety and depression (median: 36, 42, respectively) and high levels of perceived social support from their significant ones, their family and friends (median: 24, 24, 17, respectively). After multiple regression factors that were found to have an impact on depression after taking into account all other factors, were patient's age of above 70 years, patient's anxiety and the social support they received from their significant ones. More specifically, patients aged above 70 years had 9.51 points higher depression than patients aged <50 years of age (β = 9.51, 95% CI: [0.76, 18.25], P = .034). Moreover, one point increase in patient's anxiety score indicated an increase of 0.71 points in patient's depression (β = 0.71, 95% CI: [0.43, 1.00], P = .001). On the contrary, one point increase in patient's social support from their significant ones indicated a decrease of 1.52 points in patient's depression (β = -1.52, 95% CI: [-0.25, -2.79], P = .020). Clinically, a better understanding of factors having an impact on depression on DFU may provide an essential in planning cost effective interventions.

Abstract
Diabetic foot ulcer (DFU) is a major complication of diabetes mellitus that needs a multidisciplinary approach. The purpose of this study was to assess the impact of patients’ characteristics, anxiety/depression, and adherence to guidelines on the QoL of patients with diabetic ulcer. The sample of the study consisted of 195 patients. Data collected by the completion of SF-36 Health Survey, the Hospital Anxiety and Depression Scale, and a questionnaire that measured adherence to self-care activities. Patients had moderate- to high-quality levels in emotional well-being, pain, social functioning, and energy/fatigue (median: 68, 68, 63, and 60, respectively), while they had low levels of quality in physical functioning, role physical, and role emotional (median: 21, 0, and 33, respectively). In their general health, patients had moderate levels (median: 50). High levels of anxiety and depression were observed in 13.8% and 20.0% of the participants, respectively. After multiple regression, regarding general QoL, patients living in the capital city had 9.89 points worse general health than patients living in Attica (β = −9.89, 95% confidence interval [CI] = −16.86 to 2.93, P = .006). Patients with moderate or high levels of anxiety had 9.37 and 16.08 points, respectively, worse general health than those with low levels (β = −9.37, 95% CI = −17.04 to 1.70, P = .017, and β = −16.08, 95% CI = −26.65 to −5.51, P = .003, respectively). Clinically, these findings may help health professionals attain effective treatment of emotional burden to DFU patients and increase adherence to self-care.

Propranolol Versus Metoprolol for Treatment of Electrical Storm in Patients With Implantable Cardioverter-Defibrillator. J Am Coll Cardiol 2019; 71:1897-1906. [PMID: 29699616 DOI: 10.1016/j.jacc.2018.02.056] [Citation(s) in RCA: 60] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/08/2018] [Revised: 01/29/2018] [Accepted: 02/15/2018] [Indexed: 11/16/2022]
Abstract
BACKGROUND Electrical storm (ES), characterized by unrelenting recurrences of ventricular arrhythmias, is observed in approximately 30% of patients with implantable cardioverter-defibrillators (ICDs) and is associated with high mortality rates. OBJECTIVES Sympathetic blockade with β-blockers, usually in combination with intravenous (IV) amiodarone, have proved highly effective in the suppression of ES. In this study, we compared the efficacy of a nonselective β-blocker (propranolol) versus a β1-selective blocker (metoprolol) in the management of ES. METHODS Between 2011 and 2016, 60 ICD patients (45 men, mean age 65.0 ± 8.5 years) with ES developed within 24 h from admission were randomly assigned to therapy with either propranolol (160 mg/24 h, Group A) or metoprolol (200 mg/24 h, Group B), combined with IV amiodarone for 48 h. RESULTS Patients under propranolol therapy in comparison with metoprolol-treated individuals presented a 2.67 times decreased incidence rate (incidence rate ratio: 0.375; 95% confidence interval: 0.207 to 0.678; p = 0.001) of ventricular arrhythmic events (tachycardia or fibrillation) and a 2.34 times decreased rate of ICD discharges (incidence rate ratio: 0.428; 95% CI: 0.227 to 0.892; p = 0.004) during the intensive care unit (ICU) stay, after adjusting for age, sex, ejection fraction, New York Heart Association functional class, heart failure type, arrhythmia type, and arrhythmic events before ICU admission. At the end of the first 24-h treatment period, 27 of 30 (90.0%) patients in group A, while only 16 of 30 (53.3%) patients in group B were free of arrhythmic events (p = 0.03). The termination of arrhythmic events was 77.5% less likely in Group B compared with Group A (hazard ratio: 0.225; 95% CI: 0.112 to 0.453; p < 0.001). Time to arrhythmia termination and length of hospital stay were significantly shorter in the propranolol group (p < 0.05 for both). CONCLUSIONS The combination of IV amiodarone and oral propranolol is safe, effective, and superior to the combination of IV amiodarone and oral metoprolol in the management of ES in ICD patients.

Water quality modelling of the Mekong River basin: Climate change and socioeconomics drive flow and nutrient flux changes to the Mekong Delta. THE SCIENCE OF THE TOTAL ENVIRONMENT 2019; 673:218-229. [PMID: 30991313 DOI: 10.1016/j.scitotenv.2019.03.315] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/02/2019] [Revised: 03/19/2019] [Accepted: 03/20/2019] [Indexed: 05/28/2023]
Abstract
The Mekong delta is recognised as one of the world's most vulnerable mega-deltas, being subject to a range of environmental pressures including sea level rise, increasing population, and changes in flows and nutrients from its upland catchment. With changing climate and socioeconomics there is a need to assess how the Mekong catchment will be affected in terms of the delivery of water and nutrients into the delta system. Here we apply the Integrated Catchment model (INCA) to the whole Mekong River Basin to simulate flow and water quality, including nitrate, ammonia, total phosphorus and soluble reactive phosphorus. The impacts of climate change on all these variables have been assessed across 24 river reaches ranging from the Himalayas down to the delta in Vietnam. We used the UK Met Office PRECIS regionally coupled climate model to downscale precipitation and temperature to the Mekong catchment. This was accomplished using the Global Circulation Model GFDL-CM to provide the boundary conditions under two carbon control strategies, namely representative concentration pathways (RCP) 4.5 and a RCP 8.5 scenario. The RCP 4.5 scenario represents the carbon strategy required to meet the Paris Accord, which aims to limit peak global temperatures to below a 2 °C rise whilst seeking to pursue options that limit temperature rise to 1.5 °C. The RCP 8.5 scenario is associated with a larger 3-4 °C rise. In addition, we also constructed a range of socio-economic scenarios to investigate the potential impacts of changing population, atmospheric pollution, economic growth and land use change up to the 2050s. Results of INCA simulations indicate increases in mean flows of up to 24%, with flood flows in the monsoon period increasing by up to 27%, but with increasing periods of drought up to 2050. A shift in the timing of the monsoon is also simulated, with a 4 week advance in the onset of monsoon flows on average. Decreases in nitrogen and phosphorus concentrations occur primarily due to flow dilution, but fluxes of these nutrients also increase by 5%, which reflects the changing flow, land use change and population changes.

Abstract
The purpose of this research was to explore the association between state and trait anxiety experienced by patients who had undergone traumatic amputation and their family caregivers. The sample studied consisted of 50 hospitalized patients who had undergone traumatic amputation and 50 family caregivers. The collected data included patients' and caregivers' characteristics and the State Trait Anxiety Inventory scores. Fifty percent of patients and caregivers scored below 50 and 47, respectively (median), in trait anxiety. In terms of state anxiety, at least 50% of patients and caregivers scored below 56 and 50.5, respectively. These values indicate moderate to high levels of the impact of amputation on the trait and state anxiety of amputees and their caregivers. A positive linear correlation was found between the trait and state anxiety of the patients as well as between the trait and state anxiety of caregivers, as expected (ρ = 0.915, P < .001, and ρ = 0.920, P < .001, respectively). A statistically significant positive correlation was also observed between state patient anxiety and state anxiety of caregivers (ρ = 0.239 and P = .039) and between trait patient anxiety and trait anxiety of caregivers (ρ = 0.322 and P = .030). More specifically, as the patient's anxiety score (either trait temporary) increases, the score of the caregivers' anxiety increases and vice versa. Nurses should be aware of the association between anxiety of amputees and caregivers and, therefore, work in multidisciplinary teams to maximize clinical outcomes for patients after amputation and their families.

Abstract
PURPOSE To identify the latest data on interventions in the management of malignant fungating wounds (WFWs). METHODS A systematic review has been conducted to explore the original research about symptom management of malignant fungating wounds. Keywords and time constraints were used for the period 2008-2017 using the online Medline database (NCBI) with combined inclusion and exclusion criteria. RESULTS Eleven original research studies met the inclusion criteria. Nine of them referred to the use of materials and methods for managing the main symptoms which are malodour, exudate, pain and bleeding. An improvement in symptoms was observed in the involving intervention studies. According to the results, odor and exudates were significantly decreased by the use of honey and silver dressings. Wound cleaning with saline or tap water and the use of metronidazole had also positive results. Pain management was performed by the systematic use of opioids and the administration of an additional dose prior to the dressing change. CONCLUSION Patients with MFWs need a holistic treatment approach. They often seek late for health services and professional help. The disease is already locally advanced and a variety of symptoms leads to suffering and low quality of life. The effective management of symptoms by health professionals is vital to support patients in advanced disease. The need for constant briefing and updating of knowledge is imperative.

Abstract
Introduction: Wind instrumentalists require a sophisticated functioning of their respiratory system. Aim: The purpose of this research is to examine the function of the respiratory system of wind instrumentalists. Material and methods: Thirty-two adult professional musicians from two philharmonic bands (Piraeus and Zografou Municipality) participated in the survey. Each participant, after completing a questionnaire given, went through two spirometric tests, one before and one after the rehearsal. The rehearsal lasted one hour and a half and included low-mid and high frequency notes. Respiratory volumes measured and analyzed were, vital capacity (VC), maximum expiratory volume of air in 1st second (FEV1), forced vital capacity (FVC), forced expiratory flow (FEF), and Tiffenau index (FEV1/FV%). Results: The results showed that: 1) Participants did not show any noticeable change in their respiratory volumes before and after rehearsal. 2) Wind instrument players do not have a VC greater than their predicted age, height, weight and gender. 3) There is no statistically significant difference between the first and second assessment of respiratory indicators for smokers and non-smokers. 4) Regarding the type of instrument: a) Those who played wooden instruments improved the FEV1/FVC% indicator to a remarkable percentage between the first and second spirometry and b) individuals playing wooden instruments had a lower FVC, FEV1 and VC score than those playing bronze. Conclusion: There is no significant strain sign in respiratory system even in smokers after exercising in wind instrument. There is an improvement in Tiffenau index in those who played wooden instruments between the two rehearsals. Undoubtedly, new research is needed to combine a respiratory disease scenario with a respiratory treatment program that involves practicing a wind instrument.

Real-world data on Len/Dex combination at second-line therapy of multiple myeloma: treatment at biochemical relapse is a significant prognostic factor for progression-free survival. Ann Hematol 2018; 97:1671-1682. [PMID: 29756171 PMCID: PMC6097756 DOI: 10.1007/s00277-018-3361-2] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2018] [Accepted: 05/02/2018] [Indexed: 11/26/2022]
Abstract
We evaluated progression-free survival (PFS) rate of patients treated with lenalidomide/dexamethasone (Len/Dex), the efficacy of the combination, and the prognostic significance of treatment at biochemical vs. clinical relapse on PFS in 207 consecutive myeloma patients treated with Len/Dex in second line, according to routine clinical practice in Greece. First-line treatment included bortezomib-based (63.3%) or immunomodulatory drug-based (34.8%) therapies; 25% of patients underwent autologous stem cell transplantation. Overall response rate was 73.4% (17.8% complete response and 23.7% very good partial response); median time to best response was 6.7 months. Overall, median PFS and 12-month PFS rate was 19.2 months and 67.6%, respectively. 67.5% of patients had biochemical relapse and 32.5% had clinical relapse prior to initiation of Len/Dex. Median PFS was 24 months for patients treated at biochemical relapse vs. 13.2 months for those treated at clinical relapse (HR:0.63, p = 0.006) and the difference remained significant after adjustment for other prognostic factors. Type of relapse was the strongest prognostic factor for PFS in multivariate analysis. These real-world data confirm the efficacy of Len/Dex combination at first relapse; more importantly, it is demonstrated for the first time outside a clinical trial setting that starting therapy with Len/Dex at biochemical, rather than at clinical relapse, is a significant prognostic factor for PFS, inducing a 37% reduction of the probability of disease progression or death.

The efficacy of probiotics as pharmacological treatment of cutaneous wounds: Meta-analysis of animal studies. Eur J Pharm Sci 2017; 104:230-239. [PMID: 28392493 DOI: 10.1016/j.ejps.2017.04.002] [Citation(s) in RCA: 39] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2016] [Revised: 04/01/2017] [Accepted: 04/02/2017] [Indexed: 11/29/2022]
Abstract
The aim of the current meta-analysis of animal studies was to evaluate the efficacy of probiotics as pharmacological treatment of cutaneous wounds. A systematic electronic literature search was conducted and in total six animal studies which undertake twelve experiments met our inclusion criteria. We used the percentage (%) of wound area at the end of the first week after initial wounding to evaluate the efficacy of the probiotic treatment. The heterogeneity was estimated as statistically significant (p<0.0001) and therefore the meta-analysis was performed with the random-effect model. Based on the estimated Hedges' g (Hedges, 1982), the administration of probiotics was associated with acceleration of the wound contraction (g=-2.55; 95%CI=-3.59, -1.50; p<0.0001). The meta-regression analysis showed that the moderator sterile kefir extract has the greater effect on the overall estimated efficacy of probiotic treatment (g=-5.6983; p=0.0442) with bacteria probiotic therapies (70% kefir gel, L. brevis, L. fermentum, L. plantarum, L. reuteri) following (g=-2.3814; p=0.0003). For bacteria dose moderator, the results showed that increase in bacterial dose corresponds to increase of the estimated overall effect size (g=-10.2056; p=0.0053). The linear regression test of funnel plot asymmetry showed absence of publication bias. In conclusion, the results indicate that probiotics administration is an effective pharmacological treatment of cutaneous wounds. However, due to the heterogeneity among studies, further research is required.

Effect of ATP-binding Cassette Transporter A1 (ABCA1) Gene Polymorphisms on Plasma Lipid Variables and Common Demographic Parameters in Greek Nurses. Open Cardiovasc Med J 2016; 10:233-239. [PMID: 27990182 PMCID: PMC5120382 DOI: 10.2174/1874192401610010233] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2015] [Revised: 09/20/2015] [Accepted: 10/22/2015] [Indexed: 12/03/2022] Open
Abstract
Objective: The present study is on line with our previous studies evaluating the influence of ATP-binding cassette transporter A1 (ABCA1) gene polymorphisms on the lipid variables of Greek student-nurses. The current study was undertaken to (1) estimate the influence of variant(s) such as rs2066715 (V825I), R219K, R1587K, I883M of ABCA1 gene on lipid variables and (2) evaluate the effect of all four ABCA1 polymorphisms on common demographic parameters. Methods: The study population involved 432 unrelated nurses (86 men) who were genotyped for ABCA1 polymorphisms and correlated according to lipid variables [total cholesterol (TC), triglycerides (TGs), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and apolipoprotein (apo) A] and demographic parameters (age, gender, BMI, waist circumference). Results: According to lipid variables concentration there was no difference between genotypes and alleles of V825I, R219K and I883M polymorphisms. The LDL-C concentration was 13% lower in RR compared with RK genotype (100.7 vs. 113.9 mg/dl, p=0.013) of R1587K gene polymorphism. In regression analysis the effects of age, gender and only R1587K gene polymorphism on LDL-C concentrations were proved significant. Additionally, LDL-C was increased (by 1.29 mg/dl on average) by every year of increase of age. Moreover, females had lower LDL-C concentrations as compared with males. Conclusion: Findings suggested that only R1587K polymorphism of ABCA1 gene was associated with lipid variables, age, and gender of Greek nurses. These findings may be helpful in assessing the risk factors for premature coronary heart disease and distinct individuals with lower/higher atherosclerotic burden.

ATP-binding cassette transporter A1 gene polymorphisms and serum lipid levels in young Greek nurses. Lipids Health Dis 2011; 10:56. [PMID: 21489276 PMCID: PMC3090361 DOI: 10.1186/1476-511x-10-56] [Citation(s) in RCA: 22] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2011] [Accepted: 04/13/2011] [Indexed: 11/10/2022] Open
Abstract
OBJECTIVE The ATP-binding cassette transporter A1 (ABCA1) is essential protein involved in lipid metabolism. The present study was undertaken to detect the possible association of polymorphisms in the ABCA1 gene [rs2230806 (R219K) and rs2230808 (R1587K)] and lipid profile in Greek young nurses. METHODS The study population consisted of 308 unrelated nurses who were genotyped and the ABCA1 polymorphisms were detected. Additionally, lipid profile [total cholesterol (TC), triglycerides (TGs), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and apolipoprotein (apo) A] was evaluated. RESULTS There was no difference in the genotypic and allelic frequencies of the R219K polymorphism according to lipid profile. The R1587K genotypes differed significantly according to TC, LDL-C and TGs concentration (p = 0.023, p = 0.014 and p = 0.047, respectively). Particularly, significant difference in TC, LDL-C and TGs concentration was detected between RK and RR genotypes (p = 0.006, p = 0.004, p = 0.014, respectively). Women with RK genotype compared to RR genotype had higher concentration of TGs (134.25 mg/dl vs 108.89 mg/dl, p = 0.014, respectively), total cholesterol (207.41 mg/dl vs 187.69 mg/dl, p = 0.006, respectively), and LDL-C (110.6 mg/dl vs 96.9 mg/dl, p = 0.004, respectively). CONCLUSIONS These findings suggest that the R1587K polymorphism of ABCA1 gene was associated with lipid profile of Greek nurses. Women with RK genotype had higher TGs, total and LDL-C concentration compared to RR genotype. These observations may be significant in assessing the risk of CAD since a 1% change in LDL-C is associated with a 1% change of cardiovascular events. Also, TGs concentration were documented to play a significant role in women. However, this needs to be confirmed by larger studies.

Abstract
Ten patients with small angle intermittent exotropia of 14 to 16 prism diopters were treated by unilateral lateral rectus muscle recession of 11.5 to 12 mm on the nondominant eye. In the immediate postoperative phase, overcorrection of 4 to 6 delta gave a very good functional result. Abduction deficiency was minimal for recession up to 12 mm. This procedure should be considered as an alternative approach in the treatment of small angle intermittent exotropia showing a "basic" pattern.

Cytotoxic effects on viable human leukemic cells by combinations of lymphokine activated killer cells and monoclonal antibodies. Leuk Res 1989; 13:87-91.

Abstract
Earlier studies with individually phenotyped monoclonal antibody combinations and complement or lymphokine activated killer (LAK) cells showed that many acute myeloid leukemic cells were resistant to these cytotoxic agents when used singly. Therefore, a combination of both agents was studied. When the leukemic target cells were submitted to killer cells activated with 100 or 800 IU of recombinant interleukin-2 (rIL-2), only averages of 6.0 and 16.7% of the targets were killed respectively. When the remaining, refractory cells were confronted with a cocktail of individually phenotyped monoclonal antibodies and complement, an additional significant cell kill was obtained, but it amounted to only between 7.4 and 5.5% (for LAK-100 and LAK-800, respectively). In contrast, of the target cells initially refractory to the same cocktail of monoclonal antibodies, all were cross-resistant both to LAK-cells activated with 100 and to those activated with 800 IU of rIL-2. This cross-resistance was caused neither by sub-optimal LAK-cell activation, nor by antibody blocking of hypothetical LAK-cell receptors, since pre-incubation with monoclonal antibodies without complement did not inhibit LAK-cell cytotoxicity. Although only partial cross-resistance was found in the present study, it still remains that only a minority of the tumor cells could be killed. A higher in-vitro cell kill should be attempted prior to clinical trials in order to avoid clinical effects resembling those of a partial surgical tumor resection.

Abstract
Granulocyte-macrophage colony forming units (CFU-GM) were studied in cultures of bone marrow from 16 apparently healthy normal controls, 9 patients with the myelodysplastic syndrome, 5 patients with myeloproliferative disease and 2 with myeloma. Supernatants from non-stimulated 72 hr cultures of nonadherent mononuclear blood cells ("lymphocytes") stimulated the forming of an average of 38.4 colonies per 100,000 cells from normal marrow. The addition of GIBCO's commercial conditioned medium or of a medium produced by lymphocytes stimulated with different concentrations (5, 10 and 20 mcg/ml) of an acid lysate of thymus (thymomoduline), increased growth to 65.2 - 55.4 colonies (p less than 0.001 to 0.05). Similarly, a significant increase (p less than 0.05) was found in the number of clusters and colonies formed in cultures of marrow from patients with the myelodysplastic syndrome. In contrast, no growth was found when the thymus acid lysate was added directly to the bone marrow cultures, suggesting that the lysate induces the production of colony stimulating activity by lymphocytes, but does not contain it. Similarly no significant increase was found as regards the initially high number of colonies from the five patients with myeloproliferative disease, or as regards the initially low number in the two myeloma patients.
