The project has a digitally enhanced integrated patient-centered care approach clinical decision and associated intelligent tools with the aim to increase patients’ independence, quality of life and intrinsic capacity. In this paper, the conceptual aspects of the CAREPATH project, in terms of technical and clinical requirements and considerations, are presented.

This paper aims to review the published papers on telepathology projects and compare them in several aspects such as telepathology method,telecommunication method, clinical outcome, etc. Methods: PubMed database was used to find the studies published in the past ten years (2004–2014). Data were extracted from these studies based on the following items: country, national (in country) or international (between countries), frozen section or slide, body part, type of camera used, telecommunication method, telepathology method, clinical outcome, cost evaluation, satisfaction evaluation and the description of consultation providers and receivers. Results: Results showed that most of the studies were performed in developed countries on a national level, on slide and on a specific body part. In most...

In this study, we investigated and evaluated the supervised machine learning methods to predict OSA. We used popular machine learning algorithms to develop the prediction models, using a dataset with non-invasive features containing 231 records. Based on the methodology, the CRISP-DM, the dataset was checked and the blanked data were replaced with average/most frequented items. Then, the popular machine learning algorithms were applied for modeling and the 10-fold cross-validation method was used for performance comparison purposes. The dataset has 231 records, of which 152 (65.8%) were diagnosed with OSA. The majority was male (143, 61.9%). The results showed that the best prediction model with an overall AUC reached the Naïve Bayes and Logistic Regression classifier with 0.768 and 0.761, respectively. The SVM with 93.42% sensitivity and the Naïve Bayes o...

Diagnostic ways, including sonography, do not have an explicit reporting structure. Purpose To create a structure template for NAFLD reporting, investigate its completeness, and assess the specialist opinions of using it in clinical practice. Material and Methods A structured reporting template (SRT) was designed and implemented in four stages. At first, important features were extracted from a comprehensive literature review and were evaluated by 10 radiologists and gastroenterologists using the Likert scale. Finally, the usefulness of the SRT in comparison with the conventional reporting template (CRT) was judged by 10 gastroenterologists completing the questionnaire. Results Demographic information and sonography of the liver, gallbladder, and spleen organs were the most critical features. The completeness scores ...

This study was intended to assess nutritional support and its' efficacy in the Intensive Care Units (ICUs) of Iran. METHODS This cross-sectional study assessed 50 ICU's patients out of 25 hospitals in the 10 major regions of Iran's health system and was performed using the multistage cluster sampling design. The data were collected from patient's medical records, ICU nursing sheets, patients or their relatives from 2017 to 2018. Nutritional status was investigated by modified NUTRIC score and food frequency checklist. RESULTS This study included 1321 ICU patients with the mean age of 54.8 ± 19.97 years, mean mNUTRIC score of 3.4 ± 2.14, and malnutrition rate of 32.6%. The mean time of first feeding was the second day and most of patients (66%) received nutrition support, mainly through enteral (57.2%) or oral (37%) route during ICU stay. The patients received 59.2 ± 37.78 percent of required calorie and 55.5 ± 30.04 percent of required protein. Adequate intake of energy and protein was provided for 16.2% and 10.7% of the patients, respectively. The result of regression analysis showed that the odds ratio of mNUTRIC score was 0.85 (95% confidence interval [CI] = 0.74-0.98) and APACHE II was 0.92 (95%CI = 0.89-0.95) for the prediction of energy deficiency. Nutrition intake was significantly different from patient's nutritional requirements both in terms of energy (p < 0.001) and protein (p < 0.001). Also, mean mNUTRIC score varied notably (p = 0.011) with changing in energy intake, defined as underfeeding, adequate feeding, and overfeeding. CONCLUSION The present findings shown that, provided nutritional care for ICU patients is not adequate for their requirements and nutritional status.

We investigated the dynamic effects of ongoing HIV diagnoses, lower mortality due to treatment and growth in the MSM population over time on these two epidemic indicators using national HIV/AIDS surveillance data in New Zealand, 1985–2009. The diagnosed HIV prevalence pool rose 79% between 1989 and 1999, and 137% between 1999 and 2009. Estimates of diagnosed HIV prevalence as a proportion of MSM were 0.2% of MSM in 1985, and were between 1.5% and 5.0% of MSM by 2009. New Zealand continues to have a relatively low-prevalence HIV epidemic among MSM; however, the number of MSM living with diagnosed infection is growing rapidly 25 years after HIV testing was introduced.
