CHRONIC OBSTRUCTIVE PULMONARY DISEASE GROUP B AND C: ARE THEY REALLY THE OPPOSITE OF EACH OTHER REGARDING EXERCISE CAPACITY AND MUSCLE STRENGTH?

WOS: 000446023500003Purpose: 'Combined COPD Assessment' in the classification of chronic obstructive pulmonary disease (COPD) was proposed as a new method by The Global Initiative for Chronic Obstructive Pulmonary Disease (GOLD). The aim of this study was to evaluate exercise capacity, and muscle strength (respiratory and peripheral muscle strength) between two groups (Group B and C) of the new GOLD combined COPD assessment in this study. Methods: Patients were categorized into group B (n=18) and C (n=18) according to the GOLD combined COPD assessment. Patients' exercise capacity (the six-minute walk test [6MWT]) and the six-minute pegboard and ring test (6PBRT]), respiratory muscle strength (maximal inspiratory pressure [MIP] and maximal expiratory pressure [MEP]), and peripheral muscle strength (hand-grip and knee extensor strength) were assessed. Results: The MEP value was significantly higher in group B than in group C (p=0.024). Other values (6MWT distance, 6PBRT score, MIP values, and peripheral muscle strength) were not significantly different between the two groups (p>0.05). Conclusion: This study shows that comprehensive assessment is very important to evaluate patients with COPD. The GOLD spirometry measures are not solely enough, symptoms and exacerbation history must be evaluated

Investigation of phage and molasses interactions for the biocontrol of E. coli O157:H7

Resistance to antibiotics is one of the most critical health problems in the world. Therefore, finding new treatment methods to be used as alternatives to antibiotics has become a priority for researchers. Similar to phages, certain products containing antimicrobial components, such as molasses, are widely used to eliminate resistant bacteria. Molasses has a strong antimicrobial effect on bacterial cells, and this effect is thought to be due to the breakdown of the cytoplasmic cell membrane and cell proteins of the polyphenols in molasses. In the present study, phage–molasses interactions were investigated to examine the effects of concomitant use. It was found that molasses samples increased the size of phage plaques by up to 3-fold, and MIC and 1/2 x MIC concentrations of molasses increased the burst size of phages. Although no synergistic effect was found between the phage and molasses, the antimicrobial activities of the components and the effect of molasses on phage activity were demonstrated. © 2022, Canadian Science Publishing.

Test-retest reliability and validity of the timed up and go test and 30-second sit to stand test in patients with pulmonary hypertension

Background: Timed up and go (TUG) and sit to stand (STS) tests that required less space and easier to be performed in respiratory and cardiac diseases for assessing functionality. Aim was to test the reliability of TUG and 30-second STS (30STS) tests and determine the validity of TUG and 30STS tests in patients with Pulmonary Hypertension (PH). Methods: Thirty-eight patients with diagnosed PH were included. We collected TUG, 30STS, quadriceps muscle strength, physical activity level, and 6MWT. Intra-class correlation coefficient (ICC) was used to determine test-retest reliability and correlations with quadriceps muscle strength, physical activity level and 6MWT for validity of the TUG and 30STS tests. Results: The TUG and 30STS tests were associated with age, functional class, muscle strength, physical activity and functional exercise capacity in patients with PAH (p < 0.05). 6MWT was associated with age, functional class, muscle strength, physical activity and functional exercise capacity (p < 0.05). ICC (95%) for TUG test and 30STS were 0.96 (0.93-0.98) and 0.95 (0.90-0.97), respectively. Conclusions: The TUG and 30STS tests were reliable and valid tests for measuring physical performance in PH. This study supports using the TUG and 30STS tests as practical assessment tools in patients with PH. (C) 2020 Elsevier B.V. All rights reserved

Balance performance in patients with heart failure

Background: It has been suggested that patients with heart failure (HF) have an increased fall rate. Although balance is one of the most important risk factors for fall, there is not sufficient information about balance in HF. Objective: To compare static, dynamic and functional balance between patients with HF and healthy controls. Methods: Twenty-seven patients with HF and 22 healthy controls were recruited in this study. The Unilateral Stance (US) and Limits of Stability (LOS) tests were used to measure static and dynamic balance, respectively. Functional balance was assessed with Berg Balance Scale. Results: There was no significant difference in age, gender and body mass index between the groups (p > 0.05). There was a significant difference in US with open eyes between the groups (p < 0.05). Reaction time (backward and left), endpoint excursion (backward), maximum excursion (forward and backward) and directional control (forward and right) variables of LOS were significantly different between the groups (p < 0.05). Conclusions: Patients with HF have impaired static, dynamic and functional balance. Considering the balance impairment, a comprehensive balance assessment performed and balance training should be included in the management of HF as a part of the cardiac rehabilitation program. © 2020 Elsevier Inc

Tampa Scale of Kinesiophobia for Heart Turkish Version Study: cross-cultural adaptation, exploratory factor analysis, and reliability

PURPOSE: Individuals with cardiac problems avoid physical activity and exercise because they expect to feel shortness of breath, dizziness, or chest pain. Assessing kinesiophobia related to heart problems is important in terms of cardiac rehabilitation. The Tampa Scale of Kinesiophobia Swedish Version for the Heart (TSK-SV Heart) is reliable and has been validated for cardiac diseases in the Swedish population. The aim of this study was to investigate the reliability, parallel-form validity, and exploratory factor analysis of the TSK for the Heart Turkish Version (TSK Heart Turkish Version) for evaluating kinesiophobia in patients with heart failure and pulmonary arterial hypertension. METHODS: This cross-sectional study involved translation, back translation, and cross-cultural adaptation (localization). Forty-three pulmonary arterial hypertension and 32 heart failure patients were evaluated using the TSK Heart Turkish Version. The 17-item scale, originally composed for the Swedish population, has four factors: perceived danger for heart problem, avoidance of exercise, fear of injury, and dysfunctional self. Cronbach’s alpha (internal consistency) and exploratory factor analysis were used to assess the questionnaire’s reliability. Results of the patients in the 6-minute walk test, International Physical Activity Questionnaire, and Nottingham Health Profile were analyzed by Pearson’s correlation analysis with the TSK Heart Turkish Version to indicate the convergent validity. RESULTS: Cronbach’s alpha for the TSK Heart Turkish Version was 0.75, indicating acceptable internal consistency. Although exploratory factor analysis showed a different subgroup distribution than the original questionnaire, the model was acceptable for the four-factor model hypothesis. Therefore, the questionnaire was rated as reliable. CONCLUSION: These results supported the reliability of the TSK Heart Turkish Version. Since the acceptable four-factor model fits the subgroups and measures of reliability are sufficiently high, the questionnaire seems reliable for pulmonary arterial hypertension and heart failure patients

Habits of using social media and the internet in psoriasis patients

Introduction: Psoriasis significantly affects the patients quality of life, which often leads patients to seek online information about this disease. Objectives: To explore the habits of patients with psoriasis related to their use of social media (SM) and the internet to obtain information about their disease. Methods: 1,520 patients completed the survey and the Dermatology Life Quality Index (DLQI) questionnaire. The Psoriasis Area Severity Index scores (PASI) and clinical data of the patients were recorded by their physicians. Results: Of the 1,114 patients that reported using SM and internet, 48.38% regularly and 31.14% sometimes resorted to obtain information about psoriasis. The use of SM and internet for psoriasis was statistically significantly higher among young people (P = 0.000), those with university or higher education (P = 0.009), higher DLQI (P = 0.000) and PASI (P = 0.011) scores, facial (P = 0.050), scalp (P = 0.032), hand (P = 0.048), genital (P = 0.001) and inverse (P = 0.000) involvement, and arthralgia/arthritis (P = 0.006). The participants mostly used the Google (86%) and Facebook (41%). More than half of the participants (62.8%) expected dermatologists to inform society that psoriasis is not contagious. Conclusions: Internet and SM being widely available and offering substantial information to be easily accessed make it very attractive for patients to use these platforms to investigate diseases, including psoriasis. If what is presented on SM conflicts with what the physician says, patients mostly trust the latter, but at the same time, they tend not to share the results of their online inquiries with their physicians

Nuclear anomalies in the buccal cells of calcite factory workers

The micronucleus (MN) assay on exfoliated buccal cells is a useful and minimally invasive method for monitoring genetic damage in humans. To determine the genotoxic effects of calcite dust that forms during processing, MN assay was carried out in exfoliated buccal cells of 50 (25 smokers and 25 non-smokers) calcite factory workers and 50 (25 smokers and 25 non-smokers) age- and sex-matched control subjects. Frequencies of nuclear abnormalities (NA) other than micronuclei, such as binucleates, karyorrhexis, karyolysis and ‘broken eggs', were also evaluated. Micronuclei and the other aforementioned anomalies were analysed by two way analysis of covariance. The linear correlations between the types of micronucleus and nuclear abnormalities were determined by Spearman's Rho. There was a positive correlation between micronuclei and other types of nuclear abnormalities in accordance with the Spearman's Rho test. Results showed statistically significant difference between calcite fabric workers and control groups. MN and NA frequencies in calcite fabric workers were significantly higher than those in control groups (p < 0.05). The results of this study indicate that calcite fabric workers are under risk of significant cytogenetic damage

Conclusion: We present the largest cohort of children and adolescents with hyperprolactinemia in the literature to date. Hyperprolactinemia is more common in females and cabergoline is highly effective and practical to use in adolescents, due to its biweekly dosing. Indications for surgery in pediatric cases need to be revised

Diagnosis of comorbid migraine without aura in patients with idiopathic/genetic epilepsy based on the gray zone approach to the International Classification of Headache Disorders 3 criteria

BackgroundMigraine without aura (MwoA) is a very frequent and remarkable comorbidity in patients with idiopathic/genetic epilepsy (I/GE). Frequently in clinical practice, diagnosis of MwoA may be challenging despite the guidance of current diagnostic criteria of the International Classification of Headache Disorders 3 (ICHD-3). In this study, we aimed to disclose the diagnostic gaps in the diagnosis of comorbid MwoA, using a zone concept, in patients with I/GEs with headaches who were diagnosed by an experienced headache expert.MethodsIn this multicenter study including 809 consecutive patients with a diagnosis of I/GE with or without headache, 163 patients who were diagnosed by an experienced headache expert as having a comorbid MwoA were reevaluated. Eligible patients were divided into three subgroups, namely, full diagnosis, zone I, and zone II according to their status of fulfilling the ICHD-3 criteria. A Classification and Regression Tree (CART) analysis was performed to bring out the meaningful predictors when evaluating patients with I/GEs for MwoA comorbidity, using the variables that were significant in the univariate analysis.ResultsLonger headache duration (&lt;4 h) followed by throbbing pain, higher visual analog scale (VAS) scores, increase of pain by physical activity, nausea/vomiting, and photophobia and/or phonophobia are the main distinguishing clinical characteristics of comorbid MwoA in patients with I/GE, for being classified in the full diagnosis group. Despite being not a part of the main ICHD-3 criteria, the presence of associated symptoms mainly osmophobia and also vertigo/dizziness had the distinguishing capability of being classified into zone subgroups. The most common epilepsy syndromes fulfilling full diagnosis criteria (n = 62) in the CART analysis were 48.39% Juvenile myoclonic epilepsy followed by 25.81% epilepsy with generalized tonic-clonic seizures alone.ConclusionLonger headache duration, throbbing pain, increase of pain by physical activity, photophobia and/or phonophobia, presence of vertigo/dizziness, osmophobia, and higher VAS scores are the main supportive associated factors when applying the ICHD-3 criteria for the comorbid MwoA diagnosis in patients with I/GEs. Evaluating these characteristics could be helpful to close the diagnostic gaps in everyday clinical practice and fasten the diagnostic process of comorbid MwoA in patients with I/GEs
