Alexithymia is widely recognized as the inability to identify and express emotions. It is a construct which consists of four cognitive traits such as difficulty in identifying feelings, describing feelings to others, externally oriented thinking, and limited imaginative capacity. Several studies have linked alexithymia to cognitive functioning, observing greater alexithymia scores associated with poorer cognitive abilities. Despite Alzheimer’s disease (AD) being a neurodegenerative pathology characterized by cognitive troubles from the early stages, associated to behavioral and emotional disturbances, very few investigations have studied the alexithymia in AD. These studies have shown that alexithymia scores—assessed with Toronto Alexithymia Scale (TAS)—were greater in AD patients than healthy participants. The objective of the study was to investigate if the alexithymia was present in patients with mild AD. We hypothesized that the AD group would show more alexithymia features than the control group. We evaluated 54 subjects, including 27 patients diagnosed with mild AD and 27 normal healthy controls, using the Shalling Sifneos Psychosomatic Scale (SSPS-R) and a neuropsychological test battery. Using non-parametric statistical analyses—Wilcoxon and Mann–Whitney U tests—we observed that the SSPS-R scores were similar in the AD and control groups. All participants showed SSPS-R scores below to 10 points, which means no-alexithymia. We did not find significant correlations between SSPS-R scores and cognitive variables in both groups (p > 0.22), but we observed a negative association between name abilities and alexithymia, but it does not reach to significance (p = 0.07). However, a significant correlation between SSPS-R score and mood state, assessed using Zerssen Rating Scale, was found in both groups (p = 0.01). Because we did not find a significant difference in the alexithymia assessment between both subject groups, pot hoc analyses were computed for each item of the SSPS-R. We made comparisons of alexithymic responses percentages in each SSPS-R item between AD and control groups, using Fisher’s test. We observed that AD patients produced more alexithymic responses in some items of SSPS-R test than the control group, particularly about difficulties to find the words to describe feelings, as well as difficulties of imagination capacity and externally oriented thinking. The present results do not confirm our hypothesis and they do not support the results of previous studies revealing great alexithymia in AD.

It is well known that abnormalities in the brain serotonin system exist in patients with dementia. The present study was performed in order to investigate whether a peripheral serotonin system marker, the platelet 5-HT2A receptor, is affected in dementia. Thirty-eight patients with Alzheimer's disease (AD), 13 patients with vascular dementia, and 40 healthy controls were included in the study. There were no significant differences in receptor density for 5-HT2A receptor binding between the groups. Affinity of the radioligand to the receptor was significantly lower in AD than in vascular dementia and in the controls (p = .006 and p = .003, respectively), whereas there was no significant difference between the vascular dementia group and the control group. In 12 patients, treatment with citalopram was started due to depression or agitation. This treatment significantly reduced the Behavioral Pathology in Alzheimer's Disease Rating Scale scores (p = .001), but did not affect the platelet 5-HT2A receptor status. There was no correlation between 5-HT2A receptor status before treatment and the therapeutic effect of citalopram. The study indicates that platelet 5-HT2A receptor status is of limited value as a peripheral marker in dementia.

AbstractResearch results indicate systemic odor identification deficits in patients with Alzheimer’s disease (AD). The aims of this study were: 1) to compare the ability to identify different odors and to compare cognitive status among patients with AD, patients with vascular dementia (VaD) and a comparison group of elderly persons; 2) to test the efficiency of olfactory and neuropsychological measures to classify patients and 3) to relate the odor identification ability with cognitive functioning for each group, respectively. The participants were 15 patients with AD, 11 patients with VaD and 30 non-demented elderly persons, age range 58 to 90. To assess olfactory function, we used the Scandinavian Odor-Identification Test. To assess cognitive functions, we used the Dementia Rating Scale-2, the Clock Drawing Test, the Boston Naming Test and the Category Fluency Test. The ANOVA showed that patients with AD correctly identifed significantly fewer odors presented to them compared to patients with VaD and control group. Patients with AD achieved significantly lower scores on all neuropsychological measures compared to the control group and differ in the DRS-2 total score, initiation/perseveration, constructive and naming abilities comparing to patients with VaD. Discriminant analysis showed that category fluency and olfactory identification were the best predictors of AD. Significant correlations were found between the olfactory and initiation/perseveration, memory and animal naming abilities for patients with AD. Differences among patients with AD, VaD and elderly persons exist in their abilities to identify odors. The findings suggest that olfactory functional testing in combination with memory testing are important.

We aim to investigate whether a popular hand exercise could be used to improve the action of eating in patients with Alzheimer’s disease (AD). A 6-month intervention was conducted in 60 patients with AD who live in a nursing home. They were divided into hand exercise and control groups. Patients of the control group maintained their daily routine. The improvement of Edinburgh Feeding Evaluation in Dementia scale in hand exercise group was significantly greater than in the control group ( P = .003). Significant differences in time of autonomous eating and time of simulated eating between patients in the hand exercise and control groups ( P < .05) were noted. The improvements in accuracy of eating action and coordination of eating action from baseline were significant in hand exercise group compared to the control group ( P = .020 and .014, respectively). Hand exercise is a safe and effective intervention to improve the feeding and eating of people with AD.

This study aimed to identify the effect of distraction technique involving squeezing a squishy object on pain in children during intravenous catheter insertion. In this work, the control group posttest-only quasiexperimental design was used. This study involved 50 participants aged 3-15 years and was assigned into either intervention or control group. The intervention group was provided with a squishy object to squeeze as a form of distraction during intravenous catheter insertion, whereas the control group received the standard intervention. The pain was measured by using the Wong- Baker Faces Scale for 3-8 years old and the Visual Analog Scale or Numeric Rating Scale for children older than 8 years. Mann–Whitney analysis reveals significant difference in pain level between the intervention and control groups (P<0,001; α=0.05). The distraction technique involving squeezing a squishy object effectively reduced pain in children during intravenous catheter insertion and is recommended for pain management in nursing care in the pediatric ward.

ABSTRACTThe amount of liver polyploidy in a group of patients with Alzheimer's disease (AD) was compared with that of an age-matched control group. There was great variability in the percentage of cells in each ploidy class from one individual to the next in both control and AD subjects. AD patients had a lower percentage of 2N cells, and a higher percentage of 4N cells than the controls. There was no difference in the percentage of 8N or 16N cells in AD, indicating that there was no shift to higher ploidy classes in AD. The most stringent statistical analysis failed to reveal statistically significant differences between the AD and control groups.

An effective and safe remedy for shoulder pain is needed as shoulder pain is a common complication of stroke and restricts recovery of patients. This study was carried out to evaluate the effect of Ouhyul herbal acupuncture point injection (O-API) on shoulder pain in patients with stroke. Twenty-four participants with shoulder pain after stroke were recruited and randomized to the O-API and control groups. Treatment was conducted for 2 weeks three times per week. We evaluated the effects of treatment with a numerical rating scale (NRS), painless passive range of motion (PROM) of external shoulder rotation, and the Fugl-Meyer Motor Assessment (FMMA) at baseline, each week, and 1 week after the final treatment. All measures were similar between the O-API and control groups at baseline. The O-API group showed significant improvement on the NRS compared with that in the control group after 2 weeks of treatment, and the treatment effect was maintained until the follow-up period. PROM decreased significantly in both groups, but the reduction was maintained only in the O-API group. No significant difference was observed on the FMMA between the two groups. O-API resulted in significant improvement in shoulder pain after stroke, and its effect was maintained after termination of treatment without any severe side effects.

Background: Alzheimer’s disease is the most common cause of dementia. Metals such as zinc , copper, iron are likely involved in the neurodegeneration of Alzheimer’s disease . Copper can catalyze a flux of reactive oxygen species that can damage functional and structural macromolecules in brain. Most studies found association of high serum copper level with Alzheimer’s disease but also some studies did not. Methods: Total 48 patients of Alzheimer’s disease who were diagnosed according to NIA-AA ( National institute of Aging – Alzheimer’s Association) recommendation ( revised NINCDS-ADRDA) criteria were taken as study population purposively and 42 age and sex matched control were selected. Fasting serum copper level were done for both groups. Comparison of serum copper level of Alzheimer’s patients with that of the control group were done to see association. Results : A total of 28 male and 20 female with mean age of 66.20 ± 9.42 (mean±SD) years, 22 male and 20 female with mean age of 63.54 ± 9.74 (mean±SD) years constituted as case and control groups, respectively. The mean of serum copper in case and control groups were 0.95 ± 0.37 versus 0.92 ± 0.25 mg/L (P > 0.05). The present study found that serum copper levels are non-significantly higher in patients with AD than control group, however it did not show a significant relationship with severity of dementia. Conclusion: So our suggestion was to perform a study work including total serum copper level , serum ceruloplasmin level and free serum copper level comparing between a large Alzheimer’s Disease patients group and age , sex matched apparently healthy control group to understand the copper dyshomeostasis in Alzheimer’ Disease.

Introduction: Alzheimer's disease is the most common neurodegenerative disorder, characterized by the formation of amyloid plaques and the neurofibrillary tangles in the brain of an ill person, leading to neuronal damage and loss. Activation of astrocytes and astrogliosis occurs along with this process. Due to ethical limitations in working with human tissue, numerous transgenic animal models have been developed to study the pathogenesis of these processes. Early Ab deposition is observed in the cortex and the hippocampus. Aim: This study aimed to determine the difference in the presence of GFAP positive cells in the hippocampus between transgenic 5xFAD mice aged 36 weeks and their corresponding controls. Material and Methods: The 5xFAD mice model of Alzheimer's disease was used, characterized by early formation of amyloid plaques but without the presence of neurofibrillar tangles. Transgenic and control animals were sacrificed at 36 weeks of age. The visualization of GFAP-positive cells in the hippocampus of their brains was done by using immunohistochemistry and antibody for glial fibrillary acidic protein - GFAP, the major marker of astrocytes. Quantification of immuno-reactivity was done by using the Icy software system. Results: There was a statistically significant difference in the expression of GFAP in the dentate gyrus and the granular zone of the hippocampus between the transgenic and control group at 36 weeks of age, while the significant change in the CA1-3 regions was not observed between investigated groups. Conclusion: Obtained results confirm the involvement of astrogliosis in the pathophysiology of Alzheimer's disease and indicate an earlier occurrence of astrogliosis in the dentate gyrus and granular zone, in relation to other regions of the hippocampus, in the 36-week-old 5xFAD mice.

Introduction: The role of virgin coconut oil in the treatment of allergic rhinitis is controversial. Thus, the aim of the present study is to determine the effects of virgin coconut oil ingestion, in addition to standard medications, on allergic rhinitis. We also studied the side effects of consumption of virgin coconut oil. Methods: Fifty two subjects were equally divided into test and control groups. All subjects received a daily dose of 10mg of loratadine for 28 days. The test group was given 10ml of virgin coconut oil three times a day in addition to loratadine. The symptoms of allergic rhinitis were scored at the beginning and end of the study. Results:, the symptom score were divided into nasal and non-nasal symptom scores. Sneezing score showed a significant difference, however the score was more in control group than test group, indicating that improvement in symptom was more in control group. The rest of the nasal symptom and non-nasal symptom score showed no significant difference between test and control groups. Approximately 58% of the test subjects developed side effects from consumption of virgin coconut oil, mainly gastrointestinal side effects. Conclusion: In the present study, ingestion of virgin coconut oil does not improve the overall and individual symptoms of allergic rhinitis, furthermore it has side effects.

OBJECTIVESurgical site infection (SSI) after posterior spinal surgery is one of the severe complications that may occur despite administration of prophylactic antibiotics and the use of intraoperative aseptic precautions. The use of intrawound vancomycin powder for SSI prevention is still controversial, with a lack of high-quality and large-scale studies. The purpose of this retrospective study using a propensity score–matched analysis was to clarify whether intrawound vancomycin powder prevents SSI occurrence after spinal surgery.METHODSThe authors analyzed 1261 adult patients who underwent posterior spinal surgery between 2010 and 2018 (mean age 62.3 years; 506 men, 755 women; follow-up period at least 1 year). Baseline and surgical data were assessed. After a preliminary analysis, a propensity score model was established with adjustments for age, sex, type of disease, and previously reported risk factors for SSI. The SSI rates were compared between patients with intrawound vancomycin powder treatment (vancomycin group) and those without (control group).RESULTSIn a preliminary analysis of 1261 unmatched patients (623 patients in the vancomycin group and 638 patients in the control group), there were significant differences between the groups in age (p = 0.041), body mass index (p = 0.013), American Society of Anesthesiologists classification (p < 0.001), malnutrition (p = 0.001), revision status (p < 0.001), use of steroids (p = 0.019), use of anticoagulation (p = 0.033), length of surgery (p = 0.003), estimated blood loss (p < 0.001), and use of instrumentation (p < 0.001). There was no significant difference in SSI rates between the vancomycin and control groups (21 SSIs [3.4%] vs 33 SSIs [5.2%]; OR 0.640, 95% CI 0.368–1.111; p = 0.114). Using a one-to-one propensity score–matched analysis, 444 pairs of patients from the vancomycin and control groups were selected. There was no significant difference in the baseline and surgical data, except for height (p = 0.046), between both groups. The C-statistic for the propensity score model was 0.702. In the score-matched analysis, 12 (2.7%) and 24 (5.4%) patients in the vancomycin and control groups, respectively, developed SSIs (OR 0.486, 95% CI 0.243–0.972; p = 0.041). There were no systemic complications related to the use of vancomycin.CONCLUSIONSThe current study showed that intrawound vancomycin powder was useful in reducing the risk of SSI after posterior spinal surgery by half, without adverse events. Intrawound vancomycin powder use is a safe and effective procedure for SSI prevention.
