Sovateltide (ILR-1620) Improves Motor Function and Reduces Hyperalgesia in a Rat Model of Spinal Cord Injury.

BACKGROUND: Spinal cord injury (SCI) presents a major global health challenge, with rising incidence rates and substantial disability. Although progress has been made in understanding SCI's pathophysiology and early management, there is still a lack of effective treatments to mitigate long-term consequences. This study investigates the potential of sovateltide, a selective endothelin B receptor agonist, in improving clinical outcomes in an acute SCI rat model. METHODS: Thirty male Sprague-Dawley rats underwent sham surgery (group A) or SCI and treated with vehicle (group B) or sovateltide (group C). Clinical tests, including Basso, Beattie, and Bresnahan scoring, inclined plane, and allodynia testing with von Frey hair, were performed at various time points. Statistical analyses assessed treatment effects. RESULTS: Sovateltide administration significantly improved motor function, reducing neurological deficits and enhancing locomotor recovery compared with vehicle-treated rats, starting from day 7 post injury. Additionally, the allodynic threshold improved, suggesting antinociceptive properties. Notably, the sovateltide group demonstrated sustained recovery, and even reached preinjury performance levels, whereas the vehicle group plateaued. CONCLUSIONS: This study suggests that sovateltide may offer neuroprotective effects, enhancing neurogenesis and angiogenesis. Furthermore, it may possess anti-inflammatory and antinociceptive properties. Future clinical trials are needed to validate these findings, but sovateltide shows promise as a potential therapeutic strategy to improve functional outcomes in SCI. Sovateltide, an endothelin B receptor agonist, exhibits neuroprotective properties, enhancing motor recovery and ameliorating hyperalgesia in a rat SCI model. These findings could pave the way for innovative pharmacological interventions for SCI in clinical settings.

Can the Day of the Week and the Time of Birth Predict the Mode of Delivery According to Robson Classification?

Worldwide, the cesarean section rate has steadily increased from 6.7% in 1990 to 21.1% in 2018 and is expected to rise even more. The World Health Organization propose the adoption of the Robson classification system as a global standard for monitoring, evaluating, and comparing delivery rates. The purpose of the current study is to use the Robson classification system to investigate how, independently of medical factors, the day of the week and time of delivery may be related to the mode of birth. In the sample analysis, we included the records of 8572 women giving birth in one private health facility in Greece. Over 60% of deliveries during the study period were performed by cesarean section, 30.6% by vaginal delivery, and 8.5% of deliveries were performed by operative vaginal delivery. The results of this study indicate that the lowest birth rates are observed on Monday, Saturday, and Sunday. Nulliparous women with no previous cesarean delivery, with a singleton in cephalic presentation ≥37 weeks with spontaneous labor (group 1) are 73% more likely to deliver by cesarean section between 08:00 A.M. and 03:59 P.M. compared to those who give birth between 12:00 A.M. and 07:59 A.M. Also, multiparous women with a single cephalic term pregnancy and one previous cesarean section (group 5.1) are 16.7 times more likely to deliver by cesarean section in the morning compared to overnight deliveries. These results point out two non-clinical variables that influences the CS rate. The Robson classification system was a useful tool for the above comparisons.

Implementation of the Robson Classification in Greece: A Retrospective Cross-Sectional Study.

Cesarean sections have become the most commonly performed operations around the world. The World Health Organization recommended the use of the Robson classification system as a universal standard to establish a joint control system in healthcare facilities. The aim of this study was to implement the Robson classification for the first time in Greece to identify trends in cesarean births and examine the groups of women who are the main contributors to the increasing rates. Moreover, the indicators for cesarean sections will be evaluated as per the Robson classification. In the sample analysis, we included the records of 8572 women giving birth in one private health facility in Greece. A total of 8572 women gave birth during the study period, of which 5224 (60.9%) were cesarean section births and 3348 (39.1%) were vaginal births. In our study, according to the Robson classification, the largest contributors to the overall CS rate were as follows: (a) nulliparous women with a single cephalic term pregnancy, who were either labor induced or delivered by cesarean section before labor-Group 2 (34.6%); (b) multiparous women with a single cephalic term pregnancy and at least one previous cesarean section-Group 5 (30.7%); (c) women with a single cephalic preterm pregnancy-Group 10 (11.7%); (d) women with multiple pregnancies-Group 8 (7.0%). Our study is expected to assist policymakers in Greece in planning further interventions for each subgroup of women in order to reduce the overall CS rate and unnecessary CSs.

Sexual Function in Women Survivors of Hematologic Malignancy after Autologous Hematopoietic Stem Cell Transplantation.

A multicenter, cross-sectional study was conducted to assess the sexual function of women survivors of hematologic malignancy after autologous hematopoietic stem cell transplantation (AHSCT), and to compare it with that of healthy women controls. Fifty-six sexually active women survivors of hematologic malignancy who underwent AHSCT were recruited through convenience sampling, as well as 60 healthy women. Demographic and clinical data questionnaires and the Female Sexual Function Index (FSFI) were completed. Survivors had a median age of 44 years and a median time since transplant of 3 years, while 48.2% had Hodgkin Lymphoma. Survivors reported an average level of sexual dysfunction, with a total score mean ± SD = 22.51 ± 8.95. The best sexual functioning domain was "pain" and the most affected was "orgasm". There was a statistically significant association between survivors' sexual function and age (p < 0.0005) in both the unifactorial and the multifactorial analysis. In addition, there was a statistically significant association between survivors' sexual function and functional status (p < 0.0005), menopausal status (p < 0.0005), the presence of children (p = 0.002), education (p < 0.0005), and diagnosis (p < 0.0005). Healthy women had statistically significantly higher scores in all FSFI subscales (p < 0.0005). Women survivors of hematologic malignancy, treated by AHSCT, had impaired sexual function, implying the need to implement regular sexual health assessment in survivorship care.

Sexual Function of Male Survivors of Hematological Malignancy Treated by Autologous Hematopoietic Stem Cell Transplantation: A Multicenter Controlled Observational Study.

A multicenter, observational, cross-sectional study was conducted to assess the sexual function of male survivors of hematological malignancy treated by autologous hematopoietic stem cell transplantation (AHSCT) and to compare it with that of healthy male controls. By convenience sampling, 71 sexually active male survivors of hematological malignancy who underwent AHSCT were recruited, as well as 74 healthy men. A questionnaire with demographic and clinical data and the International Index of Erectile Function (IIEF) were completed. Survivors had a median age of 47 years, a median time since transplant of 3 years, and 46.5% had Hodgkin lymphoma. Based on the IIEF, they had a high level of sexual function, with best functioning domain "erection" and worst "overall satisfaction". Healthy men had statistically significantly higher scores in all domains of the IIEF, except for "orgasm" (p = 0.205). There was a statistically significant association between sexual function and age (p < 0.0005), years since transplantation (p = 0.006), functional status (p < 0.0005), having children (p < 0.0005), relationship status (p = 0.001), education (p < 0.0005), diagnosis (p < 0.0005) and disease relapse (p = 0.017). Multivariate analysis showed that only age was a strong prognostic factor of sexual function (p < 0.0005). After age was excluded from the model, because of the strong effect it had on the dependent variable, functional status (p = 0.015), education (p = 0.002) and diagnosis (p = 0.001) had a statistically significant association with sexual function. These findings indicate the importance of sexual function for survivors' well-being and the need for implementation of integrated care plans for survivors of hematological malignancy.

The Effect of Ceratonia siliqua Supplement on Bone Mineral Density in Ovariectomy-induced Osteoporosis in Rats.

AIM: This study aimed to investigate the effect of Ceratonia siliqua on bone mineral density (BMD) as a non-pharmaceutical alternative treatment for postmenopausal osteoporosis. MATERIALS AND METHODS: Thirty mature female Wistar rats were randomly separated into three groups of 10: Control, ovariectomized (OVX), and ovariectomized-plus-C. siliqua (OVX+CS). Total and proximal BMD were measured by dual-energy X-ray absorptiometry (DEXA) in all groups before ovariectomy, and at 3 and 6 months postoperatively. At the end of the study, the femurs were subjected to a three-point bending test. RESULTS: DEXA revealed no statistically significant difference in absolute values or percentage changes for total tibial BMD between OVX+CS and OVX groups throughout the study. In the proximal tibia, both absolute values and BMD percentage changes from baseline were higher in the OVX+CS group compared to the OVX group after 3 and 6 months of C. siliqua administration. Three-point bending test revealed a significantly higher thickness index in the OVX+CS group compared to the OVX group and a higher cross-sectional area index compared to the control group. CONCLUSION: Long-term administration of C. siliqua may be considered a non-pharmaceutical alternative treatment for postmenopausal osteoporosis. Further research is required to properly investigate the effects, and suitable treatment dose and schedule.

Study protocol of a randomised controlled trial for the effectiveness of a functional partial body weight support treadmill training (FPBWSTT) on motor and functional skills of children with ataxia.

INTRODUCTION: A great heterogeneity characterises the paediatric population with ataxia, which has been studied poorly. The lack of postural control and coordination, in addition with features of the 'ataxic' gait are linked with functional limitations. Studies on physiotherapy interventions for children with ataxia are highly needed for identifying optimal training strategies for improving motor and functional related skills. METHODS AND ANALYSIS: A stratified randomised control clinical trial of a 4-week functional partial body weight support treadmill training, (5 days/week 45 min/day) and 2-month follow-up period will be applied in children with ataxia, aged 8-18 years old with Gross Motor Function Classification System II-IV. Participants will be allocated to experimental group (intervention and usual care) or control group (usual care), using stratified randomisation process into two strata (progressive and non-progressive ataxia). Participants will be assessed at baseline, by the end of the 4-week period and by the end of a 2-month period as a follow-up measurement. Motor and functional skills will be assessed using the Gross Motor Function Measure-D and E, the Pediatric Balance Scale, the 10-meter walk test, the 6-minute walk test, the Scale for Assessment and Rating Ataxia, the timed up and go test and children's spatiotemporal gait features will be assessed through GaitSens software recording over a 2 min low treadmill gait speed, while three-dimensional gait analysis will be performed for kinetic and kinematic analysis of the lower limbs in all three levels of movement. Two-way mixed Analysis of Variance (ANOVA) with factors 'intervention' (between group) and 'time' (within group) will be used for the analysis of all parameters. Analysis of Covariance (ANCOVA) will be used in case of imbalance of baseline measurements. Statistical significance will be set at p<0.05 using the statistical package SPSS V.21.00. ETHICS AND DISSEMINATION: University of West Attica (study's protocol: 14η/26-04-2021) and 'ATTIKON' General University Hospital of Athens (study's protocol: Γ ΠΑΙΔ, ΕΒΔ 149/20-3-2020). Trial results of the main trial will be submitted for publication in a peer-reviewed journal and/or international conference. TRAIL REGISTRATION NUMBER: ISRCTN54463720.

Chios Mastic Gum Consumption Has a Protective Effect on Ovariectomy-Induced Bone Loss in Rats.

The purpose of this study was to examine the potential effect of Chios Mastic Gum (CMG) consumption on bone mineral density (BMD) and strength of ovariectomized rats. CMG is a known resin used from ancient times for its beneficial biological properties. Thirty mature female Wistar rats were randomized into three equal groups: sham-operated (control), ovariectomized (OVX), and ovariectomized and administered CMG per os (OVX+CMG). BMD of the total tibia, proximal tibia, and the 6th lumbar vertebra were measured at baseline and at 3 and 6 months post ovariectomy. Bone strength was assessed with three-point-bending (3pb) of the right femur. At 3 and 6 months, BMD values of the OVX+CMG group were significantly higher for the anatomical cites evaluated than those of the OVX group. Femoral thickness assessed via 3pb had intermediate values in the treated group compared to the other groups. Cytology of vaginal smears and uterine weight of the OVX+CMG group were consistent with estrogen depletion. Gastrocnemius muscle and intraperitoneal fat ratios to body weight (BW) of the OVX+CMG group did not significantly differ from the control group. Daily consumption CMG had a protective effect on BMD of the total and proximal tibia and the 6th lumbar vertebra of the rats, without causing undesirable effects on the vaginal epithelium and uterus. The 3pb results also demonstrated a favorable effect on the thickness of rat femurs. In addition, CMG was beneficial for both the muscular system and the intraperitoneal fat/BW ratio of the rats.

Validity and reliability of the Greek version of the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form.

BACKGROUND: The aim of our study is to prove the validity and reliability of the Greek translated version of the self-report section of the American Shoulder and Elbow Surgeons (ASES) questionnaire. METHODS: A total of 108 patients with various shoulder disorders were evaluated at two different orthopedic centers. All patients answered the Greek ASES questionnaire as well as the previously validated Greek version of the Disability Arm Shoulder and Hand score. Three days after the first evaluation, a subgroup of 40 individuals was randomly selected to complete again the Greek ASES text to prove its reliability, after the test-retest procedure. Reliability was tested with Cronbach's alpha, stability by calculating the intraclass correlation coefficient and by Blant Altman plot and structural validity with the confirmatory factor analysis. RESULTS: The internal consistency of the ASES functional score and the ASES total score was 0.925 and 0.750 respectively. The intraclass correlation coefficient between initial assessment and reassessment of the ASES functional and total score was 0.951 and 0.938 (P < .001), respectively. The correlation coefficients correlation between the ASES functional and total scores with DASH total score were -0.881 and -0.759 (P < .001), respectively. CONCLUSIONS: The Greek ASES version proved to be equivalent to the English original version in evaluating different shoulder disorders in the Greek population.

The Effects of Ascorbic Acid and U-74389G on Renal Ischemia-Reperfusion Injury in a Rat Model.

BACKGROUND/AIM: U-74389G and ascorbic acid protect the cells from oxidation. This study aimed to depict their role in ischemia-reperfusion injury in a renal rat model. MATERIALS AND METHODS: Sixty Wistars rats were randomized into six groups of 10 animals each. Group A Ischemia 30 min, reperfusion 60 min; Group B Ischemia 30 min, reperfusion 120 min; Group C Ischemia 30 min, ascorbic acid administration, reperfusion 60 min; Group D Ischemia 30 min, ascorbic acid administration, reperfusion 120 min; Group E Ischemia 30 min, U-74389G administration, reperfusion 60 min; Group F Ischemia 30 min, U-74389G administration, reperfusion 120 min. We then collected tissue and blood samples. RESULTS: Histology and the significantly decreased malondialdehyde and tumor necrosis factor-α levels indicated that ascorbic acid was superior to U-74389G, at pre-defined time intervals. CONCLUSION: Ascorbic acid and U-74389G ameliorated renal damage induced by ischemia-reperfusion injury, suggesting a therapeutic effect.

Complementary Therapies for Patients with Cancer: Reflexology and Relaxation in Integrative Palliative Care. A Randomized Controlled Comparative Study.

Objectives: Comparison of the effects of reflexology and relaxation on pain, anxiety, and depression, and quality of life (QoL) of patients with cancer. Design: A stratified random sample was selected, using an experimental design. Location: An outpatient Palliative Care Unit in Attica, Greece. Subjects: 88 patients suffering with cancer. Interventions: The sample was randomly divided into two equal groups, a reflexology and a relaxation group. The number of interventions for both groups was six 30-min weekly sessions. Outcome measures: The Greek Brief Pain Inventory (G-BPI) was used to measure pain, the Greek Hospital Anxiety and Depression Scale for screening anxiety and depression, and finally the Short Form Health Survey was used to measure QoL. Measurements of the above tools were taken three times in both groups as follows: preintervention, at fourth and at sixth week of intervention. Results: Anxiety and depression for both groups exhibited a statistically significant decrease during the observation period (p < 0.001, η2 > 0.25) but at the sixth week, there was a more significant decrease in the reflexology group compared with the relaxation group (p = 0.062, η2 = 0.044 vs. p = 0.005, η2 = 0.096 for anxiety), (p = 0.006, η2 = 0.094 vs. p = 0.001, η2 = 0.138 for depression). QoL physical and mental component measurements were significantly greater for the reflexology group (p < 0.001, η2 = 0.168 and p = 0.017, η2 = 0.071, respectively). The baseline-to-sixth week G-BPI measurements were markedly decreased for the reflexology group (p = 0.207, η2 = 0.020). Conclusions: Both interventions, relaxation and reflexology, seemed to be effective in decreasing anxiety and depression in patients with cancer. However, reflexology was found to be more effective in improving QoL (physical component) and to have a greater effect on pain management than relaxation.

Comparison of the Level of Awareness about the Transmission of Echinococcosis and Toxocariasis between Pet Owners and Non-Pet Owners in Greece.

Ζoonotic parasitic diseases that can occur through animal contact pose risks to pets, their owners and to their bond. This study aims to assess the level of knowledge about zoonoses, specifically echinococcosis and toxocariasis, among cat/dog owners and non-pet owners in Greece. Multiple-choice questionnaires were designed to obtain data regarding the knowledge of pet and non-pet owners on echinococcosis and toxocariasis, including signs and symptoms of these zoonoses, ways of transmission and precautions that need to be taken into account in order to avoid it. A total of 185 questionnaires were retrieved and data was expressed as absolute (Ν) and relative frequencies (%). Associations between pet ownership, residence and outcome variables were evaluated using the Fisher exact test and Chi-squared test, respectively. Multifactorial linear regression analysis was used to investigate the cross-sectional association between demographic characteristics and the awareness of helminthic zoonoses. All tests were two-sided and statistical significance was set at p < 0.05. Our study revealed a disturbing lack of awareness of echinococcosis and toxocariasis (mean zoonotic knowledge score 8.11 ± 3.18) independently of pet ownership. Surprisingly, in some cases the ignorance of pet owners exceeded that of non-pet owners. Given the progressive impact of toxocariasis in public health and the high prevalence of echinococcosis in the Mediterranean region, measures should be taken to inform people about zoonoses and eliminate their putative transmission.

Fibroblast Growth Factor 23 (FGF23) and Klotho Protein in Beta-Thalassemia.

Derangements in phosphate and calcium homeostasis are common in patients with beta-thalassemia. Fibroblast growth factor 23 (FGF23) is among the main hormones regulating phosphate levels, while several studies underline an interplay between iron (Fe) and FGF23. Herein, we investigated, for the first time, the serum intact molecule (iFGF23) and the carboxyl-terminal fragment (C-FGF23) and Klotho levels simultaneously in patients with beta-thalassemia major receiving iron chelation regimens in comparison to healthy control subjects. We also correlated them with the body iron burden. The observational case-control study included 81 subjects (40 thalassemic patients and 41 healthy controls). Serum iFGF23, C-FGF23 and Κlotho were measured by ELISA. Parathormone, 25-hydroxycholecalciferol, calcium, and phosphorus were measured in blood and/or urine. The degree of hemosiderosis was evaluated by assessing the serum ferritin levels and performing T2* MRI measurements. Serum C-FGF23 levels were significantly lower in patients compared to control subjects (p=0.04), while iFGF23 and Klotho levels did not differ. Serum C-FGF23 levels were negatively correlated with ferritin (r=-0,421, p=0.018), whereas there were no significant correlations of each of the three factors with the iron chelation therapy. Decreased serum C-FGF23 levels were found in ßTh patients which may be attributed to inhibition of proteolytic cleavage of iFGF23. Further studies in a greater number of patients will shed more light on the disturbances of the iFGF23, Klotho and C-FGF23 in thalassemia and their possible role in bone disease of such patients.

The effect of cancer patients' attachment orientations on their satisfaction of medical care.

PURPOSE: To assess the effect of cancer patients' attachment patterns on their satisfaction of medical care. METHODS: This was a cross-sectional design study performed in an outpatient palliative care clinic. The sample consisted of 100 cancer patients. Participants completed the Greek versions of patients' satisfaction, and attachment orientation to close others (Family, Close Friends, Medical Care Providers). RESULTS: "Information/interaction with health-care professionals" subscale positively correlated with "disease duration". "Availability of care" subscale was negatively correlated with "discomfort with closeness", "anxiety", and "avoidance". "Information/interaction with health-care professionals" positively correlated with "metastasis", "chemotherapy", and "hormonotherapy", while "availability of care" had positive correlations with "education", "chemotherapy", and "hormonotherapy". Multiple regression model showed that "discomfort with closeness" was associated with "information/interaction with health-care professionals". Similarly, "chemotherapy" and "surgery" were positively associated with "information/interaction with health-care professionals". Disease duration was associated with increased satisfaction with "information/interaction with health-care professionals". Predictors of "availability of care" were "discomfort with closeness", "education", and "avoidance". CONCLUSIONS: "Chemotherapy", "surgery" and "discomfort with closeness" predicted low satisfaction with "information/interaction with health-care professionals", while "discomfort with closeness" and "avoidance" predicted low satisfaction with "availability of care" and at the same time a high level of "education" predicted patients' satisfaction with "availability of care".

Protective effect of Glycyrrhiza glabra roots extract on bone mineral density of ovariectomized rats.

OBJECTIVE: The aim of this study was to evaluate the potential effect of the methanolic extract of plant Glycyrrhiza glabra roots on bone mineral density and femoral bone strength of ovariectomized rats. METHODS: Thirty 10-month-old Wistar rats were randomly separated into three groups of ten, Control, Ovariectomy and Ovariectomy-plus-Glycyrrhiza in their drinking water. Total and proximal tibial bone mineral density was measured in all groups before ovariectomy (baseline) and after 3 and 6 months post ovariectomy. Three-point-bending of the femurs and uterine weight and histology were examined at the end of the study. RESULTS: No significant difference was noted in bone density percentage change of total tibia from baseline to 3 months between Control and Ovariectomy-plus-Glycyrrhiza groups (+5.31% ± 4.75 and +3.30% ± 6.31 respectively, P = non significant), and of proximal tibia accordingly (+5.58% ± 6.92 and +2.61% ± 13.62, P = non significant) demonstrating a strong osteoprotective effect. There was notable difference in percentage change of total tibia from baseline to 6 months between groups Ovariectomy and Ovariectomy-plus-Glycyrrhiza (-13.03% ± 5.11 and -0.84% ± 7.63 respectively, P < 0.005), and of proximal tibia accordingly (-27.9% ± 3.69 and -0.81% ± 14.85 respectively, P < 0.001), confirming the protective effect of Glycyrrhiza glabra extract in preserving bone density of the Ovariectomy-plus-Glycyrrhiza group. Three-point-bending did not reveal any statistically significant difference between Ovariectomy and Ovariectomy-plus-Glycyrrhiza groups. Uterine weights of the Ovariectomy-plus-Glycyrrhiza group ranged between the other two groups with no statistically significant difference to each. CONCLUSIONS: Glycyrrhiza glabra root extract notably protected tibial bone mineral density loss in Ovariectomy-plus-Glycyrrhiza rats in comparison with ovariectomized rats, but did not improve biomechanical strength.

Depression as a Mediator or Moderator Between Preparatory Grief and Sense of Dignity in Patients With Advanced Cancer.

The objectives of the study were to evaluate the relationship between depression, preparatory grief, and loss of dignity in patients with advanced cancer and whether depression has a mediator and/or a mediator role between preparatory grief and dignity. The participants were 120 patients with advanced cancer who completed the Greek version of the Patient Dignity Inventory, the Greek Hospital Anxiety and Depression Scale, and the Preparatory Grief in Advanced Cancer Patients questionnaire. Depression was highly correlated with preparatory grief and loss of dignity. Additionally, strong relationship was found between preparatory grief and loss of dignity. Mediation analyses revealed that preparatory grief influenced loss of dignity as well as indirectly by its effect on depression. However, there was not any affect of depression as moderator. The effect of depression on preparatory grief in patients with advanced cancer and dignity emphasizing the need for further research to confirm the current relationship as well as the need for treatment of depression.

Depression as mediator and or moderator on the relationship between hopelessness and patients' desire for hastened death.

PURPOSE: Previous findings have shown that depression in advanced stages of cancer is associated with hopelessness and frequently with wishes for hastened death. The current study tries to investigate the relationship between hopelessness and desire for hastened death and if depression may be a moderator and/or mediator role in patients with advanced cancer. METHOD: The participants were 102 patients with advanced cancer which they completed the Beck Hopelessness Scale (BHS), the Greek Schedule of Attitudes towards Hastened Death (G-SAHD), and the Greek Beck Depression Inventory (BDI). RESULTS: Depression was highly correlated with hopelessness and desire for hastened death. Mediation analyses revealed that hopelessness influenced desire for hastened death as well as indirectly by its effect on depression. Similarly, depression was found as moderator in the relationship between hopelessness with desire for hastened death. CONCLUSIONS: Hopelessness and desire for hastened death in patients with advanced cancer should be diagnosed and treated by taking into consideration the optimum care of depression as a priority in palliative care.

Psychometric Properties of the Multidimensional Scale of Perceived Social Support in Greek Nurses.

BACKGROUND: Psychosocial well-being in the workplace may increase retention of oncology nurses, while a lack of social support has been a predictor of occupational stress in nurses. PURPOSE: To further explore this phenomenon by examining the psychometric properties of the Multidimensional Scale of Perceived Social Support in Greek nurses working in oncology and mental health settings. METHODS: A cross-sectional design was used. The sample consisted of 150 nurses (70 oncology nurses and 80 mental health nurses) from the area of greater Athens who joined the study. The scale was translated to Greek using the "forward-backward" procedure. The Multidimensional Scale of Perceived Social Support's internal consistency reliability (Cronbach's α), stability (intraclass correlation coefficient), factor structure (factor analysis), and convergent validity (correlation with Ways of Coping Questionnaire) were examined. RESULTS: A three-factor (significant others, family, and friends) model was confirmed. The subscales representing the three factors demonstrated excellent internal consistency reliability (Cronbach's αs > .90) and stability intraclass correlation coefficient (>.90). CONCLUSIONS: The measure is reliable and valid, and it can be used to assess nurses' social support; the results of such an assessment could be helpful when selecting strategies for assisting nurses.

Validation of the suter questionnaire after laparoscopic sleeve gastrectomy in the Greek population.

BACKGROUND & AIMS: The purpose of this study was to validate the Greek version of Suter questionnaire in order to be used for the evaluation of patients after Laparoscopic Sleeve Gastrectomy (LSG). METHODS: A total of 170 patients were enrolled in the study. RESULTS: The correlation coefficients for criterion validity had range between 0.202 (Food Tolerance) and 0.252 (Suter Total Score) (p < 0.05).There was moderate correlation between the questionnaire's subscales and the Hematocrit which satisfied the criterion validity marginally. The internal consistency measured with Cronbach's alpha yielded a value of 0.866 for the factor tolerance and 0.78 for the factor symptoms, which indicate excellent internal consistency. Excellent test-retest reliability with ICC of 0.997 for food tolerance and 0.990 for symptoms were also observed. The Suter questionnaire demonstrated a high sensitivity to detect clinical changes. CONCLUSION: The Greek version of Suter questionnaire seemed to be valid and reliable to assess morbidly obese patients after LSG.

Factors Affecting Opioid Treatment in Cancer Patients.

PURPOSE: Pain is prevalent in cancer patients, appearing to be moderate to severe in more than one third of them. Despite the fact that fentanyl is widely used with effective analgesic results, some patients do not correspond to treatment, resulting in opioid change. METHODS: This is a cohort study, performed in Greek patients with cancer. Its scope was to identify potential reasons responsible for opioid change, due to transdermal-fentanyl intolerance, resulting from inadequate analgesia (pain relief<33% in 1week) and/or unacceptable adverse-events (grade≥3 at Common Terminology Criteria-v4.0). The final sample included 289 participants. To investigate responsible reasons for transdermal-fentanyl intolerance we studied its relation with patients' history, haematology, biochemistry, body-mass-index, demographic and disease related characteristics. The Eastern Cooperative Oncology Group performance status scale, the Mini Mental State Examination questionnaire, the M.D.Anderson Symptom Inventory and the Greek Brief Pain Inventory were also used to measure performance status and quality-of-life for the same reason. RESULTS: Almost one third of the patients had to change to an alternative opioid oral-morphine in order to achieve adequate analgesia or/and avoid adverse-events. The most common adverse-events observed were nausea/vomiting and sleepiness. Statistical analysis demonstrated that younger age (OR=0.976) and obesity (OR=0.29 against underweight, OR=0.39 against normal, OR=0.48 against pre-obese) had a higher possibility to contribute to modification of the analgesic treatment. Furthermore, a higher impact of symptoms in patient's life (OR=1.184) and chemotherapy (OR=2.109) could also contribute to the need of change of the opioid analgesic medication. CONCLUSION: This study found significant variables for transdermal-fentanyl intolerance. This knowledge may help person-center care in moderate to severe cancer pain. This article is open to POST-PUBLICATION REVIEW.
