Classification of patients with chronic disease by activation level using machine learning methods.

Patient Activation Measure (PAM) measures the activation level of patients with chronic conditions and correlates well with patient adherence behavior, health outcomes, and healthcare costs. PAM is increasingly used in practice to identify patients needing more support from the care team. We define PAM levels 1 and 2 as low PAM and investigate the performance of eight machine learning methods (Logistic Regression, Lasso Regression, Ridge Regression, Random Forest, Gradient Boosted Trees, Support Vector Machines, Decision Trees, Neural Networks) to classify patients. Primary data collected from adult patients (n=431) with Diabetes Mellitus (DM) or Hypertension (HT) attending Family Health Centers in Istanbul, Turkey, is used to test the methods. [Formula: see text] of patients in the dataset have a low PAM level. Classification performance with several feature sets was analyzed to understand the relative importance of different types of information and provide insights. The most important features are found as whether the patient performs self-monitoring, smoking and exercise habits, education, and socio-economic status. The best performance was achieved with the Logistic Regression algorithm, with Area Under the Curve (AUC)=0.72 with the best performing feature set. Alternative feature sets with similar prediction performance are also presented. The prediction performance was inferior with an automated feature selection method, supporting the importance of using domain knowledge in machine learning.

Evaluation of the Swallowing and Voice Functions in Ankylosing Spondylitis Patients.

This study aimed to evaluate the swallowing and voice functions in patients with ankylosing spondylitis. Thirty patients with ankylosing spondylitis (Group 1) and 30 healthy individuals (Group 2) were included in the study. Following the laryngoscopic evaluation of the patients, the fiberoptic endoscopic evaluation of swallowing was performed, and then, the penetration-aspiration score was determined. The participants were asked to fill the eating assessment tool form. Voice recordings obtained to evaluate sound disorders were measured acoustically and analyzed using the PRAAT program. In terms of swallowing, the penetration-aspiration score obtained as a result of the flexible endoscopic swallowing assessment and eating assessment tool score was found to be higher in Group 1 than in Group 2, and a statistically significant difference was noted (p ≤ 0.001). When analyzing the maximum phonation time (p < 0.001) and fundamental frequency (p = 0.408) values in phonation evaluation, a statistically significant difference was found between the two groups. Group 1 showed a deterioration in terms of jitter (p = 0.040) and shimmer (p = 0.007) compared to Group 2, and a statistically significant difference was noted. There was no statistically significant difference in the harmonic/noise ratio (mean ± standard deviation) between the two groups (p = 0.051). Swallowing and voice functions significantly affect quality of life. Therefore, approaches aimed to improve the associated symptoms have become increasingly important. In patients with ankylosing spondylitis, swallowing quality and phonation ability may be negatively affected. These patients should be monitored for hidden or overt food aspiration.Trial Registry: https://clinicaltrials.gov/ct2/show/NCT04437394.

Effects of nasal packing and transseptal suturing on swallowing after septoplasty.

PURPOSE: This clinical trial aimed to investigate the effects of different nasal packing methods and transseptal suture technique on swallowing after septoplasty. METHODS: This randomized prospective study consists of 180 consecutive patients with septal deviation. All the patients underwent septoplasty. All the patients were randomly assigned to three groups. In group A, transseptal sutures were used for septal stabilization. In group B, both nasal passages were packed with Merocel tampons for septal stabilization. In group C, both nasal passages were packed with Doyle silicone splints for septal stabilization. For the evaluation of swallowing, the Eating Assessment Tool (EAT-10) questionnaire and a visual analog scale (VAS) were administered to all the patients preoperatively and on the second and seventh postoperative days. RESULTS: One hundred and twenty two of the patients (67.7%) were female and 58 of them (32.2%) were male. The mean age was 32.41 ± 12.37 years (range: 18-57 years). Both EAT-10 and VAS scores on the second postoperative day were significantly higher than the preoperative scores in all the groups (p < 0.05). The transseptal suture group had significantly lower EAT-10 and VAS scores on the second postoperative day than the Merocel packing and silicone packing groups (p < 0.05). Both EAT-10 and VAS scores on the postop 7th day significantly decreased in all groups compared to the postop second day (p < 0.05). CONCLUSIONS: Septoplasty affects swallowing, regardless of whether a tampon is applied. Transeptal suturing has a lesser effect on swallowing than other techniques. Although silicone packing is a less invasive method, it negatively affects swallowing, similar to Merocel packing. The transseptal suture technique is more comfortable than the other techniques in terms of swallowing function in the postoperative period.

Awareness of sudden unexpected death in epilepsy among parents of children with epilepsy in a tertiary center.

OBJECTIVE: Sudden unexpected death in epilepsy (SUDEP) is the second leading neurological cause of potential years of lifelost after stroke. Despite growing numbers of studies on social aspects of epilepsy, there is a paucity of research on the awareness of SUDEP among the parents of children with epilepsy (CWE), especially in Turkey. In this study, we aimed to evaluate the knowledge of parents of the CWE regarding SUDEP in the tertiary setting. MATERIAL AND METHODS: A total of 146 parents (108 female) aged 19 to 55 years (median age:34) of CWE were included at Marmara University, School of Medicine, Department of Pediatric Neurology outpatient clinic between May 2018 and September 2018. A total of 30 multiple-choice questions and a written survey were administered, which consisted of three sections. In the first section, the sociodemographics of parents and CWE were questioned. In the second section, the severity of epilepsy was evaluated. In the third section, the knowledge level and awareness of parents of CWE were assessed. RESULTS: Of 146 parents, only 16.6% previously heard about SUDEP, while 45% of them heard from their relatives. The presence of prior knowledge of SUDEP was associated with the presence of prolonged postictal confusion and longer duration of epilepsy (p < 0.05). Ninety-seven (66%) parents desired to be informed about SUDEP, while 76 (54.7%) of them agreed that this information should be given at the time of diagnosis. The degree of anxiety in parents regarding death of epilepsy-related causes was significantly related with prolonged postictal confusion (p < 0.001) and using three or more antiepileptic drugs (p = 0.005). CONCLUSION: Our data suggest that knowledge about SUDEP among parents with CWE found inadequate in Turkey. There should be much effort to inform parents and caregivers in epilepsy clinics on SUDEP, which may help to reduce the associated risk factors.

The efficacy of Kinesio taping on lymphedema following head and neck cancer therapy: a randomized, double blind, sham-controlled trial.

OBJECTIVE: The aim was to investigate the effectiveness of Kinesio taping for lymphedema following head and neck cancer therapy and its effect on patient compliance and quality of life. METHODS: A total of 66 patients with lymphedema following head and neck cancer therapy were randomly allocated to the therapeutic Kinesio taping group (n = 33) and the sham Kinesio taping group (n = 33). All participants received manual lymphatic drainage, Kinesio taping, and home exercises for the first four weeks, and only home exercises for the second four weeks. The tape measurements, a scale of external lymphedema, a scale of the internal lymphedema, and quality of life were evaluated in both groups. The perceived discomfort consisting of limitation of daily living activities, pain, tightness, stiffness, and heaviness were also recorded. RESULTS: When the group x time effect was evaluated, it was observed that external lymphedema was significantly reduced in both groups according to neck and face composite measurements (p < .001). However, in these measurements, a significant difference was found between the groups in favor of the KT group (p = .001, p = .032, respectively). At the end of the study, there was no significant difference in terms of internal lymphedema in both groups (p = .860). The quality of life parameters such as global health status and swallowing were significantly better in the Kinesio taping group (p < .001). There was no significant difference in the parameters of perceived discomfort between the two groups (p = .282, p = .225, p = .090, p = .155, p = .183, respectively). CONCLUSION: Kinesio taping is effective in tape measurements and positively affects the quality of life in lymphedema following head and neck cancer therapy.

Efficacy of Kinesio taping on Mutational Falsetto: A Double Blind, Randomized, Sham-controlled Trial.

OBJECTIVES: This study aimed to assess the efficacy of Kinesio taping on male patients with mutational falsetto undergoing voice therapy. DESIGN: Double blind, randomized, sham-controlled clinical trial. PARTICIPANTS: Interviews were conducted with thirty seven mutational falsetto patients. Included 32 participants were randomized and divided into two groups. Two were dropped out due to irregular attendance, 30 participants were included in final analysis. INTERVENTIONS: The study group was treated with voice therapy and applications of three different therapeutic Kinesio taping techniques with seven Kinesio tapes four times over two weeks, and the control group was treated with voice therapy, and applied to sham Kinesio taping. OUTCOME MEASURES: The values of fundamental frequency, jitter, shimmer, noise-harmonic ratio, maximum phonation time, Voice Handicap Index-10 scores, and Grade-Roughness-Breathiness-Asthenia-Strain Scale scores were recorded at the baseline and after the two weeks. RESULTS: There were significant differences between the study group and the control group with respect to the values of fundamental frequency (P = 0.011), jitter (P = 0.041), shimmer (P = 0.036), noise-harmonic ratio (P = 0.003), maximum phonation time (P ≤ 0.001), Voice Handicap Index-10 scores (P = 0.036), and Grade-Roughness-Breathiness-Asthenia-Strain Scale scores (P = 0.007; P ≤ 0.021; P = 0.022; P = 0.002; P = 0.021, respectively) at the end of the study. CONCLUSIONS: The study demonstrated that Kinesio taping with voice therapy is an efficient and effective technique for treating mutational falsetto patients.

Relationship of muscle thickness, strength, and diaphragm function in adults with cystic fibrosis.

Objectives: This study aimed to evaluate the muscle thickness, strength, and diaphragmatic function and relate them with clinical findings. Patients and methods: The cross-sectional study was conducted with 54 participants (27 males, 27 females; mean age; 24.5±5.3 years; range, 18 to 45 years) between January 2017 and October 2017. Of the participants, 31 were adult CF patients, and 23 were age-and sex-matched controls. Patient demographics, 6-min walk distance, body mass index (BMI), and fat-free mass index (FFMI) were evaluated. Each patient underwent pulmonary function tests. Quadriceps femoris thickness and diaphragm thickening fraction were assessed by ultrasonography. Upper extremity strength was measured with a handheld dynamometer. Results: There was no difference between the patients' and controls' BMI (p=0.052). However, patients' FFMI was lower than the controls' (p=0.010). The FFMI correlated with pulmonary function tests. Patients' both right and left quadriceps femoris muscles were thinner than the controls (p=0.001 and p=0.001, respectively). Patients with pancreatic insufficiency had thinner muscles than patients without pancreatic insufficiency. The control group had a stronger handgrip than CF patients (33.5±10.1 vs. 24.5±9.2 kg, p=0.003). Conclusion: Peripheral muscle wasting and weakness and lower functional capacity are highly prevalent in CF patients.

Comparison of Isotonic Seawater Nasal Spray Containing Chamomile Liquid Extract and Other Isotonic Seawater Nasal Washing Solutions for Allergic Rhinitis.

OBJECTIVE: We aim to demonstrate the effect of an isotonic seawater spray containing chamomile liquid extract on symptoms and nasal mucociliary clearance in patients with allergic rhinitis by comparing it with other isotonic seawater nasal washing solutions. METHODS: The study included 123 patients. Based on Allergic Rhinitis and its Impact on Asthma guidelines, mometasone furoate intranasal spray treatment was started for all patients in the group diagnosed with allergic rhinitis. In addition to this treatment, isotonic seawater spray with chamomile liquid extract was added to Group A, isotonic seawater spray to Group B, and isotonic seawater nasal irrigation to Group C. The fourth group (Group D) was given only nasal steroid spray without nasal washing treatment. Before and after treatment in all patients, the Sino-Nasal Outcome Test-22 was performed, and nasal mucociliary clearance times were measured by the saccharin test. RESULTS: The differences in duration of nasal mucociliary clearance and Sino-Nasal Outcome Test-22 values were taken before and after treatment. In Group A, B, C, and D the Sino-Nasal Outcome Test-22 differences were statistically significant (P ≤.001; P ≤ .001; P ≤ .001, and P = .048, respectively). Only Group A and Group B experienced a significant difference in nasal mucociliary clearance times (P ≤ .001; P = .010, respectively). When the Sino-nasal Outcome Test-22 score and nasal mucociliary clearance time differences before and after treatment were compared between all groups, the Sino-Nasal Outcome Test-22 score difference was higher in Group A than in Groups B, C, and D, the differences were found as statistically significant (P = .010; P = .003; P ≤ .001, respectively). The nasal mucociliary clearance time difference was higher in Group A than in Groups C and D, the differences were found as statistically significant (P = .010; P = .001, respectively). CONCLUSION: Isotonic seawater spray containing chamomile liquid extract is seen as a good alternative treatment option for allergic rhinitis patients.

The clinical and histological characteristics of patients with biopsy-proven non-alcoholic fatty liver disease in the absence of insulin resistance.

Background and Aim: Non-alcoholic fatty liver disease (NAFLD) is closely associated with insulin resistance (IR). While a minority of patients with NAFLD does not have evidence of IR, no detailed characterization of this specific phenotype is currently available. This study was undertaken to investigate the clinical and histological characteristics of this patient group. Materials and Methods: We retrospectively reviewed the clinical records of 263 patients with biopsy-proven NAFLD. IR was defined by a Homeostatic Model Assessment of IR (HOMA-IR) score >2.73. The histological diagnosis of non-alcoholic steatohepatitis (NASH) was performed using 1) the steatosis, activity and fibrosis score and 2) the NASH Clinical Research Network (NASH CRN) criteria. Significant fibrosis was defined by the presence of a histological fibrosis score higher than F≥2. Patients with and without evidence of IR were compared concerning clinical, laboratory, and histological characteristics. Results: Of the 263 patients with biopsy-proven NAFLD, 53 (20.2%) patients had no evidence of IR. Patients without IR were younger [IR (-): 42 (22-65) years versus IR (+): 49 (22-71) years, p=0.001] and had a higher prevalence of men [IR (-): 39 (73.6%) versus IR (+): 113 (53.8%), p=0.009]. Moreover, they were characterized by a lower body mass index [IR (-): 30.06±3.61 kg/m2 versus IR (+): 33.19±5.06 kg/m2, p=0.000] and lower frequencies of metabolic risk factors-including the metabolic syndrome, diabetes, hypertension, hyperlipidemia, and lower waist/hip circumference. Liver histology was generally less severe in patients without IR; specifically, they showed a lower prevalence of NASH [IR (-): 38 (71.7%) versus IR (+): 190 (90.5%), p=0.000] and significant fibrosis [IR (-): 9 (17.0%) versus IR (+): 106 (50.5%), p=0.000] than did patients with IR. Multivariate analysis identified obesity [odds ratio (OR): 9.321, 95% confidence interval (CI): 1.031-84.261, p<0.05] and an international normalized ratio >1.1 (OR: 10.116, 95% CI: 1.325-77.225, p<0.05) as independent predictors of significant fibrosis in patients with NAFLD and no IR. Conclusion: Patients with NAFLD and no IR has less severe liver histology than patients with IR. However, obesity appears to be independently associated with significant fibrosis in this patient group.
