Hemodialysis Machine

We concentrate on designing a fuzzy controller, its task is management the operation of preparing the dialysate solution with the required Specifications and continuous monitoring to set the value of conductivity that takes major role to success the bloody Purification operation, where any error in this operation lead to reduce the efficiency of hemodialysis machine so the patient will face the damage. In this research, we reduced the time to treatment (TTT) by speeding the preparing operation of the dialysate solution, and achieve more reliable value of required conductivity so it reduces the alarms that result of override the allowable values which lead to stop the preparing operation and wait for the required values. The fuzzy controller gave us more efficiency when we compared with other controllers which was achieved in previous researches, so we can use the learning algorithms to make this controller more adaptive.

Abstract Pediatric patients with cancer are at high risk for severe infections and delayed treatment increases mortality. Infections can trigger changes of vital signs long before clinical symptoms arise. Continuous recording may detect such changes earlier than discrete measurements. This is the protocol for an investigator-initiated, single-center observational pilot study on the feasibility of continuous monitoring of health data with a wearable device (WD) in pediatric patients undergoing chemotherapy of cancer. A total of 20 patients will be included, including at least 4 patients <6 years. Each patient will wear the WD for 14 days and we expect study duration of three to four months. The protocol had been registered at www.clinicaltrials.com (NCT04134429) and was approved by the local Ethics Committees (Ethikkommission der Universitätskinderkliniken Bern, “Gesuch 1912”, Kantonale Ethikkommission Bern, BASEC-No.: 2019-01919).

Language Pathology

The family described in this article provides an unusual opportunity to relate findings from genetic, histological, electrophysiological, psychophysical, and rehabilitative investigation. Although the total number evaluated is large (49), the known, living affected population is smaller (14), and these are spread from age 20 to age 59. As a result, the findings described above are those of a large-scale case study. Clearly, more data will be available through longitudinal study of the individuals documented in the course of this investigation but, given the slow nature of the progression in this disease, such studies will be undertaken after an interval of several years. The general picture presented to the audiologist who must rehabilitate these cases is that of a progressive cochlear degeneration that affects only thresholds at first, and then rapidly diminishes speech intelligibility. The expected result is that, after normal language development, the patient may accept hearing aids well, encouraged by the support of the family. Performance and satisfaction with the hearing aids is good, until the onset of the speech intelligibility loss, at which time the patient will encounter serious difficulties and may reject hearing aids as unhelpful. As the histological and electrophysiological results indicate, however, the eighth nerve remains viable, especially in the younger affected members, and success with cochlear implantation may be expected. Audiologic counseling efforts are aided by the presence of role models and support from the other affected members of the family. Speech-language pathology services were not considered important by the members of this family since their speech production developed normally and has remained very good. Self-correction of speech was supported by hearing aids and cochlear implants (Case 5’s speech production was documented in Perkell, Lane, Svirsky, & Webster, 1992). These patients received genetic counseling and, due to the high penetrance of the disease, exhibited serious concerns regarding future generations and the hope of a cure.

Chronic Leg Ulcers

SummaryChronic leg ulcer may have various causes, which are currently not centrally recorded in Germany. It is also unclear who treats patients with chronic leg ulcers in Germany and how the basic implementation of diagnosis and treatment of these patients looks like. Patients, methods: Therefore, we started a survey of 1000 general practitioners and practising specialists in dermatology, surgery and phlebology in five different regions of Germany. We carried out the genesis of a total of 6275 patients from 62 different practising therapists, 33 specialists in dermatology, surgery or phlebology and 29 general practitioners. Results: In 66.1% of all patients we found a venous leg ulcer, in 9.1% a leg ulcer from peripheral arterial occlusive disease, and in 8.5% a mixture of both. Thus there suffered a total of 83.8% of patients on chronic venous insufficiency or peripheral arterial occlusive disease as a major factor in the genesis of the chronic leg ulcer. However, even the rarely diagnosed entities such as exogenous factors, vasculitis, pyoderma gangrenosum or infectious diseases are occur in summation in 16.2% of all patients and should therefore be known and excluded. In addition, the treatment periods and referral routes of patients with chronic leg ulcer should be identified. The analysis showed that the vast majority (86.8%) of patients with chronic ulcers who were investigated by us is treated by specialists. The treatment duration of general practitioners is 6.3 weeks (mean value) before the patient will be referred to a specialist. This treatment period is significantly shorter compared to the treatment period of the specialists, who treat their patients 14.1 weeks (mean value) before the patient will be referred to another specialist or to a clinic. Conclusion: Our results show the current aspects of aetiology and the way of treatment of patients with chronic leg ulcers in Germany.

The Impact

The motion picture industry is one of the largest industries worldwide and has significant importance in the global economy. Considering the high stakes and high risks in the industry, forecast models and decision support systems are gaining importance. Several attempts have been made to estimate the theatrical performance of a movie before or at the early stages of its release. Nevertheless, these models are mostly used for predicting domestic performances and the industry still struggles to predict box office performances in overseas markets. In this study, the aim is to design a forecast model using different machine learning algorithms to estimate the theatrical success of US movies in Turkey. From various sources, a dataset of 1559 movies is constructed. Firstly, independent variables are grouped as pre-release, distributor type, and international distribution based on their characteristic. The number of attendances is discretized into three classes. Four popular machine learning algorithms, artificial neural networks, decision tree regression and gradient boosting tree and random forest are employed, and the impact of each group is observed by compared by the performance models. Then the number of target classes is increased into five and eight and results are compared with the previously developed models in the literature.
