Fruit-based vegan ice cream-type frozen dessert with aquafaba: effect of fruit types on quality parameters.

"Aquafaba", defined as legume cooking water, has a feature that can be used in various formulations as an egg and milk alternative in vegan products and improves functional properties such as foaming, emulsifying and gelling. In this study, it was aimed to investigate the usability of aquafaba in ice cream type frozen desserts containing different fruit purees (strawberry, nectarine and banana) by using its foaming capacity. Rheological properties, microstructure, overrun, melting characteristics, color measurement, dry matter, and sensory properties were investigated in different fruit-based frozen dessert samples. The brix value, density, protein content, foaming capacity (FC) and foaming stability (FS), flow behavior index, consistency coefficient, and overrun of aquafaba were determined as 7.1 ± 0°Bx, 1.022 ± 0.011 g/ml, 1.51 ± 0.41%, 85 ± 0% FC and 81 ± 0.23% FS, between 0.28 and 0.64, between 8.68 and 41.30 Pa·sn, between 116.75 and 395.93%, respectively. The dry matter content of the strawberry, nectarine, and banana-based dessert samples ranged between 17 and 48%, 20-49%, 25-50%, and the first dropping times were determined between 348 and 1538 s, 369-1689 s and 435-1985 s, respectively. As a result, cooking liquid leftover aquafaba can be used as a suitable raw material in the production of an alternative ice cream type frozen dessert for individuals with milk allergy, lactose intolerance or who prefer a vegan diet.

Evaluation of self-esteem in hearing aid and cochlear implant users.

PURPOSE: We investigated the relationship between hearing aid or cochlear implant use and self-esteem, quality of life, hearing quality, and speech perception. METHODS: Of the 120 participants studied, 29 were cochlear implant users, 26 were hearing aid users, 33 were non-device users with hearing loss, and 32 had normal hearing. Each individual included in the study WHOQOL-BREF Quality-of-Life Scale, Rosenberg Self-Esteem and Speech, Spatial Perception and Qualities of Hearing Scale was applied. RESULTS: We found that the self-esteem level of the group with hearing loss, but without a device, was significantly lower than that of the group with a cochlear implant/hearing aid. There was a moderately statistically significant relationship between self-esteem, quality of life, speech perception, and hearing quality. CONCLUSIONS: Using hearing aid and cochlear implants increases self-esteem among people with hearing impairments. Self-esteem is associated with quality of life, speech perception, and hearing quality.

Adaptation of the professionalism mini-evaluation exercise instrument into Turkish: a validity and reliability study.

BACKGROUND: There is an ongoing search for standardized scales appropriate for each culture to evaluate professionalism, which is one of the basic competencies of a physician. The Professionalism Mini-evaluation Exercise (P-MEX) instrument was originally developed in Canada to meet this need. In this study, it was aimed to adapt the P-MEX to Turkish and to evaluate the validity and reliability of the Turkish version. METHODS: A total of 58 residents at Bakirkoy Dr. Sadi Konuk Training and Research Hospital were assessed with the Turkish version of P-MEX by 24 raters consisting of faculty members, attending physicians, peer residents, and nurses during patient room visits, outpatient clinic and group practices. For construct validity, the confirmatory factor analysis was performed. For reliability, Cronbach's alpha scores were calculated. Generalizibility and decision studies were undertaken to predict the reliability of the validated tool under different conditions. After the administration of P-MEX was completed, the participants were asked to provide feedback on the acceptability, feasibility, and educational impact of the instrument. RESULTS: A total of 696 forms were obtained from the administration of P-MEX. The content validity of P-MEX was found to be appropriate by the faculty members. In the confirmatory factor analysis of the original structure of the 24-item Turkish scale, the goodness-of-fit parameters were calculated as follows: CFI = 0.675, TLI = 0.604, and RMSEA = 0.089. In the second stage, the factors on which the items loaded were changed without removing any item, and the model was modified. For the modified model, the CFI, TLI, and RMSEA values were calculated as 0.857, 0.834, and 0.057, respectively. The decision study on the results obtained from the use of P-MEX in a Turkish population revealed the necessity to perform this evaluation 18 times to correctly evaluate professionalism with this instrument. Cronbach's alpha score was 0.844. All the faculty members provided positive feedback on the acceptability, feasibility, and educational impact of the adapted P-MEX. CONCLUSION: The findings of this study showed that the Turkish version of P-MEX had sufficient validity and reliability in assessing professionalism among residents. Similarly, the acceptability and feasibility of the instrument were found to be high, and it had a positive impact on education. TRIAL REGISTRATION: 2020/249, Bakirkoy Dr. Sadi Konuk Training and Research Hospital.

Translation and validation of the music-related quality of life questionnaire for adults with cochlear implant in Turkish language.

PURPOSE: It is important to assess the impact of music on cochlear implant (CI) users' quality of life. The aim of this study was to adapt and validate the music-related quality of life questionnaire into the Turkish language for adult CI users. METHODS: 161 CI users and 162 normal-hearing adults were included in the study. The final Turkish version of the questionnaire was prepared and evaluated for validity and reliability. The internal consistency of the questionnaire and test-retest reliability were evaluated by Cronbach's α and ICC index. Factor analysis and 'know-group' method was used to determine the construct validity. RESULTS: Sampling adequacy for execution of factor analysis was confirmed by the results of Kaiser-Meyer-Olkin (= 0.91) and Bartlett test (p < 0.05). 2 factors for each scale were identified from exploratory factor analysis. Confirmatory factor analysis confirmed the questionnaire met the criteria standards for adequacy of fit. The reliability coefficient was determined at least 0.80. Correlation between items indicated excellent (> .80) internal consistency. CONCLUSION: The Turkish version of the questionnaire has good validity and reliability and can be used to investigate the relationship between music and quality of life and as a diagnostic tool in identifying individuals who need music support and to guide and evaluate music rehabilitation.

Carob powder as cocoa substitute in milk and dark compound chocolate formulation.

In the current research, the possibility of using carob powder as a substitute for cocoa powder in milk and dark compound chocolates was investigated. Five chocolate samples containing carob powder (20, 40, 60, 80 and 100%) along with control were produced and the physico-chemical analyzes were measured. Chocolate samples were assessed for sensory acceptance by a hedonic scale. The outcomes indicated that chocolate formulations with lower content of carob powder presented higher quality in terms of color parameters, mean particle size and hardness (values close to control). The addition of carob powder resulted in decreased yield stress in dark chocolates. Also dark chocolate formulations containing high levels of carob powder recorded Casson viscosity values similar to control. Moreover, the milk chocolates containing 40% carob powder illustrated no significant differences in sensory properties with control. However acceptance of the dark chocolate samples was similar to control in all attributes. The results proved that it is possible to utilize carob powder to replace cocoa powder in chocolate production in order to improve nutritional values (higher fiber and fewer calories) with agreeable sensory attributes.

MATERNAL GUT MICROBIOTA IN PREGNANCIES RESULTING IN DOWN SYNDROME NEWBORNS - A PILOT STUDY.

Down syndrome (DS) is one of the main genetic abnormalities of newborns. Therefore, prenatal diagnosis of this syndrome is of paramount importance to the family and the community. The microbiota system is important in early brain development. We tried to study and compare gut microbiota (GM) composition in pregnancies that resulted in DS neonates with pregnancies that resulted in healthy children. The study population consisted of 21 pregnant women having delivered DS newborns (group 1) and 22 pregnant women who had given birth to healthy newborns (group 2). The GM composition was determined and compared between the two groups. There were no significant age and gestational age differences between the two groups (p>0.005 both). Regarding GM analysis, microorganisms of the families Clostridiaceae and Pasteurellaceae were more abundant in the group of women having delivered DS neonates than the group of women having delivered healthy newborns (p<0.05). The results of our pilot study showed that the GM system might have a role in the pathophysiology of DS. The GM changes may be used in the prenatal diagnosis and prevention of this syndrome. Further studies are needed in this field.

Genomewide Elucidation of Drug Resistance Mechanisms for Systemically Used Antifungal Drugs Amphotericin B, Caspofungin, and Voriconazole in the Budding Yeast.

There are only a few antifungal drugs used systemically in treatment, and invasive fungal infections that are resistant to these drugs are an emerging problem in health care. In this study, we performed a high-copy-number genomic DNA (gDNA) library screening to find and characterize genes that reduce susceptibility to amphotericin B, caspofungin, and voriconazole in Saccharomyces cerevisiae We identified the PDR16 and PMP3 genes for amphotericin B, the RMD9 and SWH1 genes for caspofungin, and the MRS3 and TRI1 genes for voriconazole. The deletion mutants for PDR16 and PMP3 were drug susceptible, but the other mutants had no apparent susceptibility. Quantitative-PCR analyses suggested that the corresponding drugs upregulated expression of the PDR16, PMP3, SWH1, and MRS3 genes. To further characterize these genes, we also profiled the global expression patterns of the cells after treatment with the antifungals and determined the genes and paths that were up- or downregulated. We also cloned Candida albicans homologs of the PDR16, PMP3, MRS3, and TRI1 genes and expressed them in S. cerevisiae Heterologous expression of Candida homologs also provided reduced drug susceptibility to the budding yeast cells. Our analyses suggest the involvement of new genes in antifungal drug resistance.

The effects of antibiotics and melatonin on hepato-intestinal inflammation and gut microbial dysbiosis induced by a short-term high-fat diet consumption in rats.

High-fat diet (HFD) consumption leads to metabolic disorders, gastrointestinal dysfunction and intestinal dysbiosis. Antibiotics also disrupt the composition of intestinal microbiota. The aim of the present study was to investigate the impact of a short-term feeding with HFD on oxidative status, enteric microbiota, intestinal motility and the effects of antibiotics and/or melatonin treatments on diet-induced hepato-intestinal dysfunction and inflammation. Male Sprague-Dawley rats were pair-fed with either standard chow or HFD (45 % fat) and were given tap water or melatonin (4 mg/kg per d) or melatonin plus antibiotics (ABX; neomycin, ampicillin, metronidazole; each 1 g/l) in drinking water for 2 weeks. On the 14th day, colonic motility was measured and the next day intestinal transit was assessed using charcoal propagation. Trunk blood, liver and intestine samples were removed for biochemical and histopathological evaluations, and faeces were collected for microbiota analysis. A 2-week HFD feeding increased blood glucose level and perirenal fat weight, induced low-level hepatic and intestinal inflammation, delayed intestinal transit, led to deterioration of epithelial tight junctions and overgrowth of colonic bacteria. Melatonin intake in HFD-fed rats reduced ileal inflammation, colonic motility and perirenal fat accumulation. ABX abolished increases in fat accumulation and blood glucose, reduced ileal oxidative damage, suppressed HFD-induced overgrowth in colonic bacteria, and reversed HFD-induced delay in intestinal transit; however, hepatic neutrophil accumulation, hepatic injury and dysfunction were further enhanced. In conclusion, the results demonstrate that even a short-term HFD ingestion results in hepato-intestinal inflammatory state and alterations in bacterial populations, which may be worsened with antibiotic intake, but alleviated by melatonin.

Early effect of the fear of terrorism on a hospital's emergency department use and on the incidence of cardiovascular events: A Turkish multicenter study.

BACKGROUND: To our knowledge, the early effect of the fear caused by terrorism on human health, especially its effect on the number of visits to medical emergency departments (EDs), has not yet been studied. OBJECTIVES: To observe the effect of fear from terrorist alerts on the use of EDs and on the rate of cardiovascular (CV) and/or cerebrovascular events. SETTING: In Istanbul, Turkey, there was a terror alert on the weekend of 19 and 20 March 2016. In this multicenter retrospective study, we compared the data of patients from that weekend with those from the preceding and following weekends. PATIENTS: A total of 12 324 adult patients' records were included in this study: 4562 patients in the first weekend, 3627 patients in the second, terror alert weekend, and 4135 patients in the third weekend. MEASUREMENTS: The ED, CV, and cerebrovascular incidence rates of the above three groups were compared. RESULTS: The rate of ED use was the least in the weekend of the terror alert; the highest rate occurred during the weekend prior to it (female applications decreased more [P = 0.03]). The medical center that was the farthest from the crowded central places of the city and from the place where suicide bombing occurred was less affected by the decrease in use. CONCLUSIONS: Fear associated with terrorism may affect human health indirectly by preventing patients from reaching the necessary emergency healthcare facilities. This finding may be a pathfinder to decision-makers in such extraordinary emergency conditions. Further studies are needed in this field.

Cytoplasmic abnormalities of mature oocytes have a significant effect on fertilization in Bologna poor responders

Background/aim: We aimed to investigate whether oocyte morphologic abnormalities affected cycle outcome in poor responder infertile women who fulfilled the Bologna criteria. Materials and methods: Data were obtained from infertile couples who underwent ICSI and embryo transfer at the Zeynep Kamil Maternity and Children's Health Training and Research Hospital Assisted Reproduction Unit in Istanbul, Turkey. They were allocated to two groups: Group A, poor responders, and Group B, normal responders. All morphological abnormalities of oocytes retrieved were reviewed and grouped as cytoplasmic abnormalities or extracytoplasmic abnormalities. All morphological features were compared between the poor and normal responder groups. ICSI cycle outcomes were described as biochemical pregnancy, fertilization rate, number of top-quality zygotes, top-quality zygote rate, number of embryos transferred, and number of top-quality embryos transferred. The relation between each morphological feature and ICSI outcomes was investigated in each group. Results: The results showed no difference between the groups in terms of morphological features of oocytes. The relation between ICSI cycle outcomes and each oocyte morphological feature was compared in the poor and normal responder groups. Presence of cytoplasmic morphological abnormality was found to significantly correlate with the fertilization rate (P = 0.019) in poor responders. Conclusion: Our data show that oocyte cytoplasmic abnormalities significantly reduce fertilization achievement in poor responders.

Radiologic Examination of High Riding Vertebral Artery and Analysis of Secure Areas.

OBJECTIVE: To radiologically examine the pedicle, lamina, and vertebral artery foraminal anatomies at the C2 vertebra for pedicular and laminar screw instrumentation at the axis in a Turkish population. METHODS: From 2018 to 2019, we evaluated 100 patients who underwent cervical computed tomography (CT) for various reasons (excluding cervical pathologies) at Marmara University Hospital. The C2 pedicles were measured on CT images using measurement tools. In addition, axial computed tomography was performed at 0.1 mm intervals. Bilateral measurements were performed for each case. RESULTS: The median right and left pedicle axial diameters were 5.01 and 5.09 mm, respectively for the male patients and 4.31 and 4.38 mm for the female patients, showing a statistically significant difference between the sexes (P < 0.01). Of the patients, 15% had narrow pedicles. The pedicle sagittal diameters were smaller than 5 mm in 30% of the computed tomographic series. The internal height was <2 mm in 4% of the cases. CONCLUSIONS: Our findings suggest significant individual and sex-related differences. Vertebral artery groove anomalies are commonly observed. Before performing a posterior craniocervical instrumentation surgery, a computed tomography (CT) examination is beneficial because high-riding vertebral arteries must be kept in mind in determining the appropriate screw diameter and screw trajectory.

Posterolateral Paramass Approach to Lesions Located at the Anterior C1-2 Level: A Cadaver Study.

OBJECTIVE: A novel posteriolateral surgical approach is described that will provide safe access to intradural and extradural lesions located in the anterior part of the spinal cord (SC) at the C1-2 level and to the odontoid in single session. METHODS: A total of five cadavers and two dry C1 vertebrae were used in this study. The study involved obtaining computed tomography magnetic resonance imaging scans and magnetic resonance imaging of all cadaver groups before and after the procedures. Group 1: Control; Group 2: Unilateral C1 posterior arch was removed, the inferomedial part of C1 lateral mass was removed, and access the anterior and lateral aspects of the SC. Group 3: In addition, odontoid was removed, Group 4: In addition, unilateral C1- C2 screw was placed. Group 5: In addition, bilateral C1-C2 screw was placed. RESULTS: The median distance from the midpoint of C1 posterior tubercle to vertebral groove which was removed in groups is 21.4 ± 2.88 mm. The average width of C1 lateral mass was 13.4±2.4 mm. After the lateral mass was drilled, its width decreased to 10,2 mm.This area was sufficient to open a surgical corridor and reach the anterior of SC and odontoid. After the procedure, no instability was found in group 2 without instrumentation on computed tomography and magnetic resonance imaging scans. CONCLUSIONS: It is possible to access the anterior C1-C2 via a posterolateral paramass approach by drilling 20%-30% of the lateral mass, providing an open pathway for easy intervention in C1-C2 intradural lesions. It is also possible to perform odontoid resection using this approach.

Determination of the process effect on cocoa butter crystallization by rheometer: Kinetic modeling by Gompertz equation.

In this study, the effects of temperature (22, 24, 26, 28, and 30°C) and strain (0.1%, 1%, and 5%) on cocoa butter (CB) crystallization were investigated by oscillatory test, and the four-parameter Gompertz model was used to interpret the effect of parameters on pre-crystallization, nucleation, and crystal growth stages of CB. Lag time and growth rate were calculated using the Gompertz model using time-dependent storage modulus (G') data. According to the results, CB crystallization at 26°C with a 1% strain value had the highest growth rate value, the shortest lag time, and the formation of ßv polymorph type. Followingly, polymorphic types of the CB crystals were determined based on the melting points of polymorphs via the temperature ramp step, and the results obtained were correlated with a polarized light microscope. In conclusion, using a rheometer in both the observation of the pre-crystallization process and the determination of polymorph types is very important for research and development studies in the chocolate industry for process and formulation optimization. PRACTICAL APPLICATION: This study demonstrates the feasibility of a novel approach for investigating crystallization and oscillatory shear of CB using a rheometer, both for observing crystallization kinetics and determining polymorph type, accompanied by the Gompertz equation to model the crystallization kinetics. According to the results, the effect of process parameters (temperature and shear) on the crystallization behavior of CB can be observed by rheometer, which can provide a detailed perspective for chocolate manufacturers and researchers in research and development studies.

Stem cell treatment reduces T cell apoptosis in COPD patients with chronic bronchitis but not with emphysema.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a prevalent and preventable condition. Mesenchymal stem cell (MSC) therapy is being explored to aid in the regeneration of lung cells and airway structure, aiming to restore lung function. AIM: To examine varied responses of MSCs when cultured with peripheral blood mononuclear cells (PBMCs) from different COPD phenotypes, patients were grouped into ACOS, emphysema, and chronic bronchitis categories. METHODS: PBMCs from these groups and controls were co-cultured with MSCs derived from dental follicles, revealing differing rates of apoptosis among COPD phenotypes compared to controls. RESULTS: While the chronic bronchitis group exhibited the least lymphocyte viability (p<0.01), introducing MSCs notably enhanced viability across all phenotypes except emphysema, with the chronic bronchitis group showing the most improvement (p<0.05). CONCLUSION: Stem cell therapy might reduce peripheral lymphocyte apoptosis in COPD, with varying responses based on phenotype, necessitating further research to understand mechanisms and optimize tailored therapies for each COPD subtype.

Evaluating therapeutic efficacy of extended shelf-life 90 Y glass microspheres in transarterial radioembolization for colorectal cancer: a quantitative FDG PET/CT analysis.

OBJECTIVES: There is a lack of sufficient evidence regarding the use of extended shelf-life (ExSL) Yttrium-90 ( 90 Y) glass radiomicrospheres in metastatic colorectal cancer (mCRC) patients. We aimed to investigate the efficacy of ExSL 90 Y glass radiomicrospheres with a personalized treatment approach by analyzing 18 F-FDG PET/CT quantitative parameters [metabolic tumor volume (MTV) and total lesion glycolysis (TLG)] separately before and after the treatment. METHODS: A total of 93 radioembolization sessions involving 77 patients were included. Simplicit 90 Y software was utilized to perform multicompartmental voxel-based dosimetry. Adverse events were recorded using the CTCAE v5.0 criteria. The survival data were recorded in detail. RESULTS: The overall disease control rate was 84.9%, with a median overall survival (OS) of 12.7 months and median progression-free survival (PFS) of 8.3 months. A statistically significant increase in treatment response rate was observed when there was an increase in absorbed tumor dose for pre-treatment unit MTV ( P  = 0.005) and TLG ( P  = 0.004) values. We didn't observe any additional side effects/vital risks that could be considered clinically significant. CONCLUSION: Our study has provided evidence on the therapeutic effectiveness and safety in terms of dose-toxicity profile of ExSL 90 Y glass microspheres in a large cohort of mCRC patients. With a personalized treatment approach, the increase in radiation dose absorbed by the tumor has shown a significant contribution to treatment response rate, as indicated by quantitative measurements obtained through 18 F-FDG PET/CT.

Radiation pneumonitis in relation to pulmonary function, dosimetric factors, TGFß1 expression, and quality of life in breast cancer patients receiving post-operative radiotherapy: a prospective 6-month follow-up study.

PURPOSE: To investigate development of radiation pneumonitis (RP) in relation to pulmonary function, dosimetric factors, and transforming growth factor beta-1 (TGFß1) expression in irradiated breast cancer patients. METHODS: A total of 49 breast cancer patients who received post-operative radiotherapy (RT) were evaluated in terms of pulmonary function tests (PFTs), quality of life (QoL), development of RP, dosimetric factors, cytokine levels, and lung high-resolution computed tomography (HRCT) before and after RT. ROC analysis was performed for performance of dosimetric factors in predicting RP, while frequencies of single nucleotide polymorphisms (SNPs) genotyped for TGFß1 (rs11466345 and rs1800470) were also evaluated. RESULTS: All cases with RP (10.2%) recovered clinically at the end of third post-RT month. PFT and HRCT parameters were similar before and after RT overall, as well as by RP and the radiation field subgroups. ROC analysis revealed the significant role of the ipsilateral V5 (cutoff value of 45.9%, p = 0.039), V10 (29.4%, p = 0.015), V20 (23%, p = 0.017), and MLD (1200 cGy, p = 0.030) in predicting RP. Higher post-RT TGFß1 levels (p = 0.037) were noted overall and in patients with RP. Patient and control groups were similar in terms of frequencies of SNPs genotyped for TGFß1 (rs11466345 and rs1800470). EORTC QLQ-C30 and QLQ-BR-23 scores were similar in patients with vs. without RP. CONCLUSION: Our findings revealed significant role of dosimetric factors including MLD, V20 as well as the low dose-volume metrics in predicting the risk of RP among breast cancer patients who received post-operative RT. Implementation of RT, extent of radiation field or the presence of RP had no significant impact on PFTs.

Investigation of interactions of doxorubicin with purine nucleobases by molecular modeling.

Doxorubicin, an anthracycline antibiotic with anti-tumor activity, is produced by the bacterium Streptomyces peucetius. The interactions between doxorubicin and genetic material and the details of the intercalation with DNA have been controversial issues. Thus, the interactions of doxorubicin with purine nucleobases were studied by quantum mechanical methods. Initially, conformer analyses of doxorubicin were performed with Spartan 08 software and 319 different conformers from 422 initial structures for doxorubicin were obtained. Geometry optimizations and frequency analyses were performed for each structure using density functional theory (DFT) at B3LYP/6-31G** level using Gaussian 09 software. The most stable 20 conformers of doxorubicin and tautomers of purine nucleobases were optimized again with É·B97XD/6-31G** level and their interactions were also analyzed at the same level. The Discovery Studio 3.5 Visualizer was used to draw the initial and optimized structures of investigated geometries. The noncovalent interactions (NCIs) were visualized by calculating reduced density gradient (RDG) with Multiwfn program. The color-filled isosurfaces and RDG scatter maps of most stable interaction geometries were plotted by Visual Molecular Dynamics (VMD) software and Gnuplot 5.3 software, respectively. This study showed that adenine, guanine, and hypoxanthine nucleobases interact with doxorubicin by forming strong hydrogen bonds and π-π interactions. Considering the normal cellular conditions, the effect of solvent (water) on the interaction geometries were also analyzed and when compared to gas phase it was determined that the movements of the molecules were restricted and there was a minimal change between initial and optimized structures in the aqueous phase.

Sharing social media data: The role of past experiences, attitudes, norms, and perceived behavioral control.

Social media data (SMD) have become an important data source in the social sciences. The purpose of this paper is to investigate the experiences and practices of researchers working with SMD in their research and gain insights into researchers' sharing behavior and influencing factors for their decisions. To achieve these aims, we conducted a survey study among researchers working with SMD. The questionnaire covered different topics related to accessing, (re)using, and sharing SMD. To examine attitudes toward data sharing, perceived subjective norms, and perceived behavioral control, we used questions based on the Theory of Planned Behavior (TPB). We employed a combination of qualitative and quantitative analyses. The results of the qualitative analysis show that the main reasons for not sharing SMD were that sharing was not considered or needed, as well as legal and ethical challenges. The quantitative analyses reveal that there are differences in the relative importance of past sharing and reuse experiences, experienced challenges, attitudes, subjective norms, and perceived behavioral control as predictors of future SMD sharing intentions, depending on the way the data should be shared (publicly, with restricted access, or upon personal request). Importantly, the TPB variables have predictive power for all types of SMD sharing.

Stereological and electrophysiological evaluation of autonomic involvement in amyotrophic lateral sclerosis.

OBJECTIVE: Previous studies have identified autonomic dysfunction in amyotrophic lateral sclerosis (ALS) using mostly neurophysiological techniques. In this study, stereological evaluation of autonomic fibers and sweat glands has been performed to identify structural evidence of autonomic denervation in patients with ALS. METHODS: In this study, 29 ALS patients were compared to 29 controls using COMPASS-31 questionnaire, sympathetic skin response (SSR), and heart rate variability (HRV) at rest. From the same cohorts, 20 ALS patients and 15 controls were further evaluated using staining of autonomic nerve fibers and sweat glands in skin biopsies. SSR and resting HRV were repeated in the ALS patient cohort one year later. RESULTS: COMPASS-31 total score, gastrointestinal- and urinary-sub scores were higher in ALS patients than controls (P = 0.004, P = 0.005, and P = 0.049, respectively). In the ALS patient cohort, SSR amplitudes in hands and feet were lower than in controls (P<0.0001 and P = 0.0009, respectively), but there was no difference in resting HRV (P>0.05). While there was no change in nerve fibers innervating sweat glands, their density was lower in ALS patients than controls, and semi-quantitative analysis also showed structural damage (P = 0.02 and P = 0.001, respectively). SSR and resting HRV of ALS patients remained stable during the one-year follow-up period (P>0.05). DISCUSSION: Supporting abnormal neurophysiological tests, stereological analysis revealed direct evidence of autonomic denervation in ALS patients. However, the degenerative process in autonomic nerve fibers is relatively slow, compared to the rate of motor neuron degeneration in this condition.

Effect of eTansiyon smartphone application on hypertension control.

AIM: To investigate the effectiveness of eTansiyon smartphone application in blood pressure control in patients with hypertension. BACKGROUND: Global prevalence of hypertension and the burden of chronic illness care, especially in primary care, are increasing in world. We have developed eTansiyon to ensure the continuity of patient-physician relationship, so it may help to improve the lifestyle of patients with hypertension, increase their adherence to treatment and achieve the target blood pressure. METHODS: This study was a non-randomized controlled study. The sample was selected by random sampling method among the patients registered in 6 Family Health Units (FHUs). Randomization was performed at the FHU level; the units were randomized to 4 control group (CG) and 2 intervention group (IG), so that randomization in this study was 2:1. Both groups were followed up for at least four months. In addition to CG, IG were provided to use eTansiyon. Obtained data were analysed to evaluate differences between groups at the beginning and end of the study, intra-group changes after follow-up and interaction between groups and follow-up period. FINDINGS: The study was performed with 124 patients in CG and 61 patients in IG. At the end of the study, the average systolic blood pressure/diastolic blood pressure (SBP/DBP) of office and home was significantly lower in IG compared to CG (P < 0.001, MD 9.5 mmHg; P = 0.007, MD 3.8 mmHg; P < 0.001, MD 10.6 mmHg; P < 0.001, MD 4.8 mmHg, respectively), and it was found that the proportion of people with target blood pressure in IG was significantly higher than CG (P < 0.001, 49.2%(n = 30) and 22.6%(n = 28), respectively). Repeated measures ANOVA and generalized estimating equations results showed that follow-up period and interaction between groups were significant in terms of office and home SBP/DBP and target blood pressure level during follow-up period (P < 0.001, P < 0.001, P < 0.001, P < 0.001, P < 0.024, respectively).
