A systemic review and meta-analysis on the antihypertensive effect of aromatherapy essential oils

Purpose: This study is a systemic review of experimental results on the effects of aromatherapy on blood pressure. Materials and Methods: Journal articles published to December, 2017, were retrieved from twelve databases. Randomized controlled trials in which were evaluated for changes in blood pressure following aromatherapy were selected. Risks of bias were assessed using the risk-of-bias (ROB) tool of the Cochrane Collaboration. Meta-analysis were dine using RevMan. Results: Of the 2545 articles retrieved from the electronic databases, 580 duplicate articles and 1891 articles that were unrelated to the PICO (patient/problem, intervention, comparison, outcome) elements or did not satisfy the inclusion criteria excluded. Of the remaining 74 articles, 15 found to satisfy the inclusion criteria after full-text review and therefore selected for analysis. The findings of meta-analysis of 11 of these 15 articles revealed that essential oil inhalation and massage effectively decreased both systolic (n = 379; mean difference [MD], -4.72; 95% confidence interval [CI], -8.38 to -1.07) and diastolic (n = 379; MD, -2.42; 95% CI, -4.46 to -0.38) pressure. Conclusions: Essential oil inhalation and massage therapy can effectively decrease systolic and diastolic pressure in health adults as well as in patients with hypertension

Reliability and Validity of the Severe Impairment Battery (SIB) in Korean Dementia Patients

This study was conducted to examine the reliability, validity and clinical utility of the Severe Impairment Battery (SIB) for a Korean population. 69 dementia patients with Clinical Dementia Rating (CDR) stages 2 or 3 were participated in this study. The SIB, Korean version-Mini Mental State Examination (K-MMSE), CDR, and Seoul-Activities of Daily Living (S-ADL) were administered. The validity of the SIB was confirmed by evaluating the correlation coefficients between the SIB and K-MMSE, CDR, S-ADL, which were found to be significant. Cronbach's alpha for the total SIB score and each subscale score showed high significance, and the item-total correlation for each subscale was also acceptable. The test-retest correlation for the total SIB score and subscale scores were significant, except for the praxis and orienting to name. The total SIB score and subscale scores were examined according to CDR. The results suggest that the SIB can differentiate the poor performances of severely impaired dementia patients. On the basis of the receiver operating characteristic (ROC), it can be concluded that the SIB is able to accurately discriminate between CDR 2 and 3 patients. The results of this study suggest that the SIB is a reliable and valid instrument for evaluating severe dementia patients in Korean population

Impairment of Instrumental Activities of Daily Living in Patients with Mild Cognitive Impairment

ObjectiveaaThis study was conducted to examine the following: whether patients with mild cognitive impairment (MCI) show impairments in instrumental activities of daily living (IADL) as compared to controls; to identify the functional sub-domains of instrumental activities of daily living (IADL) that are affected in MCI and, finally, to identify the Seoul-Instrumental Activities of Daily Living (S-IADL) scale cut-off score that best differentiated between MCI and controls. MethodsaaThis study was carried out at the geropsychiatry clinic, university hospital. The study participants included 66 patients with MCI and 61 normal elderly. The S-IADL and Seoul-Activities of Daily Living (S-ADL) scales were administered to the main caregivers of all participants in order to assess everyday functioning. ResultsaaThe total S-IADL score was significantly higher in the patients with MCI [mean (SD) score=4.47 (2.06)] than in the controls [mean (SD) score=1.44 (1.65)] (p<0.001). The patients with MCI performed significantly worse on IADLs, such as the ability to use the telephone, prepare meals, take medication, manage belongings, keep appointments, talk about recent events, and perform leisure activities/hobbies (p<0.05). The S-IADL scal

Do we need colonoscopy verification in patients with fundic gland polyp?

Background/AimsThe aim of this study was to evaluate the prevalence of colorectal neoplasia in subjects with fundic gland polyps (FGPs) and the relationship between FGPs and colorectal neoplasia in Korea.MethodsWe analyzed 128 consecutive patients with FPGs who underwent colonoscopy between January 2009 and December 2013. For each case, age- (±5 years) and sex-matched controls were identified from among patients with hyperplastic polyps, gastric neoplasms, and healthy controls. Clinical characteristics were reviewed from medical records, colonoscopic findings, pathologic findings, and computed tomography images. The outcome was evaluated by comparison of advanced colonic neoplasia detection rates.ResultsOf the 128 patients, seven (5.1%) had colon cancers and seven (5.1%) had advanced adenomas. A case-control study revealed that the odds of detecting a colorectal cancer was 3.8 times greater in patients with FGPs than in the age- and sex-matched healthy controls (odds ratio [OR], 3.80; 95% confidence interval [CI], 1.09–13.24; P =0.04) and 4.1 times greater in patients with FGPs than in healthy controls over 50 years of age (OR, 4.10; 95% CI, 1.16–14.45; P =0.04). Among patients with FGPs over 50 years old, male sex (OR, 4.83; 95% CI, 1.23–18.94; P =0.02), and age (OR, 9.90; 95% CI, 1.21–81.08; P =0.03) were associated with an increased prevalence of advanced colorectal neoplasms.ConclusionsThe yield of colonoscopy in colorectal cancer patients with FGPs was substantially higher than that in average-risk subjects. Colonoscopy verification is warranted in patients with FGPs, especially in those 50 years of age or older

Toxoplasma gondii Inhibits Apoptosis in Infected Cells by Caspase Inactivation and NF-κB Activation

Our experiments aimed to clarify the mechanism by which host cell apoptosis is inhibited by infection with the intracellular protozoan parasite, Toxoplasma gondii (T. gondii). Mouse spleen cells were cultured in 6-well plates with RPMI 1640/10% FBS at 37℃, in a 5% CO2 atmosphere. Apoptosis of spleen cells was induced by actinomycin-D (AD) treatment for 1 h prior to infection with T. gondii. A variety of assays were used to assess the progression of apoptosis: DNA size analysis on agarose gel electrophoresis, flow cytometry with annexin V/PI staining, and analysis of expression levels of Bcl-2 family and NF-κB mRNA and proteins by RT-PCR, Western blotting, and EMSA. Additionally, transmission electron microscopy (TEM) was performed to observe changes in cell morphology. Fragmentation of DNA was inhibited in spleen cells treated with AD and T. gondii 5 h and 18 h post infection, respectively, and flow cytometry studies showed a decreased apoptotic rates in AD and T. gondii treated spleen cells. We observed decreased expression of Bax mRNA and protein, while levels of Bcl-2 mRNA remained constant in spleen cells treated with AD and T. gondii. Caspase 3 and PARP were inactivated in cells treated with AD and T. gondii, and increased levels of cleaved caspase 8 were also observed. Analysis of EMSA and Western blot data suggests that activation of transcription factor NF-κB may be involved in the blockade of apoptosis by T. gondii. TEM analysis showed nuclear fragmentation and chromatin condensation occurring in spleen cells treated with AD; however, such apoptosis-associated morphological changes were not observed in cells treated with both AD and T. gondii tachyzoites. Together, these data show that T. gondii infection inhibits AD induced apoptosis via caspase inactivation and NF-κB activation in mouse spleen cells

Lower leg compartment syndrome following prolonged orthopedic surgery in the lithotomy position -A case report-

Surgical procedures necessitating the prolonged use of the lithotomy position can be associated with neuromuscular dysfunction. Compartment syndrome of the lower leg is a grave complication which, if unrecognized, can lead to either permanent neuromuscular dysfunction or limb loss. We report a case of compartment syndrome of lower leg that occurred in male patient aged 20 years after 380 minutes arthroscopic surgery in the lithotomy position
