Service quality monitoring in confined spaces through mining Twitter data

Promoting public transport depends on adapting effective tools for concurrent monitoring of perceived service quality. Social media feeds, in general, provide an opportunity to ubiquitously look for service quality events, but when applied to confined geographic area such as a transport node, the sparsity of concurrent social media data leads to two major challenges. Both the limited number of social media messages--leading to biased machine-learning--and the capturing of bursty events in the study period considerably reduce the effectiveness of general event detection methods. In contrast to previous work and to face these challenges, this paper presents a hybrid solution based on a novel fine-tuned BERT language model and aspect-based sentiment analysis. BERT enables extracting aspects from a limited context, where traditional methods such as topic modeling and word embedding fail. Moreover, leveraging aspect-based sentiment analysis improves the sensitivity of event detection. Finally, the efficacy of event detection is further improved by proposing a statistical approach to combine frequency-based and sentiment-based solutions. Experiments on a real-world case study demonstrate that the proposed solution improves the effectiveness of event detection compared to state-of-the-art approaches

Kidney Stone Development among Older Adults in Iran

Aim: Incidence and prevalence of kidney stone development have been increased in the recent years. Present study aimed to determine prevalence and risk factors of kidney stone development among adults more than 65 years old. Methods: This cross-sectional study conducted in Kashani Hospital at Shahrekord, Iran. Data on all adults more than 65 years who were admitted to the lithotripsy unit of Kashani hospital in Shahrekord, were derived from medical records, in the period of January 2011 to December 2011. Results: Of 1170 admitted patients to the lithotripsy unit of the hospital, 181 (15.5%) patient were older than 65 years, with 95 female (52.5%) and 86 male (47.5%). Results of independent t test showed significant difference in stone development between male and female patients (p<0.05). The age of 73.5% (n=133) of patients were in between 65 to 74 years. Results of ANOVA showed significant difference in stone development between three age groups (p<0.05). Rate of patients admission in summer with 34.3% (n=62) was higher than other seasons. Results of ANOVA showed significant difference in stone development between four seasons of year (p<0.05). Conclusion: Results of present study showed that the risk of kidney stone development in older people (more than 65) is high. In addition, female sex, age group 65-74 years, region of residence and summer season might be considered as potential risk factors for increasing the risk of kidney stone development

Short-term Effects of PM10 to Increase Rate of Hospital Admission Cardiovascular and Respiratory of Sanandaj, Iran During 2015

Sanandaj in the west of Iran is one of the main city that suffered from Arabic Dust Storm (ADS). As Sanandaj isn’t industrial city and located in the mountainous region, one of the main sources of air pollution which has adverse effects on citizens and environment is PM10 which comes from Arabic Dust Storm. In this way, the goal of this study was to the assessment of these adverse health effects. So the hourly data of concentration of PM10 (measured by Beta attenuation method) were taken from Kurdistan Environmental Protection Agency in 2015. the 24-hour average concentration of particulate matter has exceeded about 182 times (days) more than the National Standards and WHO guideline values and the average annual concentration of PM10 were about 1.5 times more than the National Standard and WHO guideline values during the period of the exam. By means of Air Q2,2,3 software the data analyzed and baseline incidence(BI), relative risk(RR) and attributable proportion(AP) were calculated. The results of this study showed that short-term health effect of PM10 could increase of total mortality except accidents and poisoning(4.13%), hospital admission cardiovascular(4.98%), cardiovascular mortality(4.45%), hospital admission respiratory(4.45%) and respiratory mortality(0.2%). This study demonstrated that a high percentage of cardiovascular and respiratory morbidity and mortality rate increased due to the raising of the concentration of PM10. To reduce the emission of PM10 from main sources and relationship between the hospital and Kurdistan Environmental Protection Agency and whether organization and people to be alert are necessary

The Effect of Religious Care by the Clergyman next to the Patients’ Bedside on their Depression and Anxiety

For downloading the full-text of this article please click here.Background and Objective: The fear of surgery, death, and the debilitating symptoms of the illness make hospitalized patients develop anxiety and depression that may disrupt their performance. Religious care aimed at addressing the religious needs of hospitalized patients can have a significant role in increasing the hospitalized patients’ ability to cope with their illness. Therefore, the researchers aimed to set up a religious-based plan and perform it by the presence of a clergy next to the patients’ bedside and determine its effectiveness on decreasing anxiety and depression of hospitalized patients.Method: In this randomized controlled clinical trial with control group, 142 hospitalized patients were chosen in the form of random sampling in Nekoui hospital of Qom. They were divided into a test and a control group. Then, the demographic questionnaire and the Hospital Anxiety Depression Scale were completed by them. The religious-based plan by the presence of a clergy next to the patients’ bedside was performed in the test group. The two groups were followed after the intervention. All ethical issues were observed in this study and the researchers declared no conflict of interests.Results: In terms of overall score of hospital anxiety and depression, the results of ANCOVA showed a statistically meaningful difference between the two groups after the intervention (F=35.75, P&lt;0.001). Also, the results of paired-samples t-test showed a significant decline in the anxiety and depression of hospitalized patients in the intervention group (P= 0.001). In contrast, no measurable difference was observed in the anxiety and depression scores of patients in the control group (P= 0.10, P= 0.48).Conclusion: The presence of special medical teams like responsible clergies who are familiar with health issues and the provision of religious care can decrease patients’ anxiety and depression. Such a religious intervention also has a significant role in boosting patients’ morale and reducing their woes.For downloading the full-text of this article please click here.Please cite this article as: ShojaeiS, AbbasiM, RahimiT, Vahedian M, FarhadlooR, Movahed E, Parvaresh-MasoudM.

Effect of metformin and folic acid on plasma homocysteine level in type 2 diabetic patients

Hyperhomocysteinemia is associated with an increased risk of cardiovascular disease in diabetic patients. The aim of this study was to evaluate effects of metformin and folic acid on plasma homocysteine level in diabetic patients. In this clinical trial 47 new cases of type 2 diabetes were randomized to two groups. We treated patients in trial group with metformin and 1 mg folic acid, whereas patients in control group treated with metformin and placebo for 16 weeks. There was no significant difference in plasma homocysteine level and glycosylated hemoglobin (HbA1c) between two groups at the start of study. After 16 weeks plasma homocysteine level in the trial group did not change. In contrast plasma homocysteine level increased in the placebo group. There was significant difference in mean plasma homocysteine level between two groups (P-value &lt; 0.01). This difference was highly significant in males (P-value &lt; 0.0001). Correlation between glycosylated hemoglobin and plasma homocysteine level at start and end of study was not significant. This finding indicated that metformin increases plasma homocysteine level in diabetic patients especially males, whereas administration of folic acid with metformin can prevent this process

Transfusion-transmitted malaria : a systematic review and meta-analysis

Background : Malaria transmission through blood transfusion is an accidental but preventable cause of malaria infection and is increasingly becoming a matter of concern for blood transfusion services. This systematic review was conducted to provide a summary of evidence about the prevalence of Plasmodium infection in asymptomatic blood donors and the effectiveness of screening methods used based on the available literature. Methods : PRISMA guidelines were followed. Scopus, PubMed, Science Direct, and EMBASE were searched from 1982 to October 10, 2017. All peer-reviewed original research articles describing the prevalence of malaria parasitemia in blood donors with different diagnostic methods were included. The random-effects model was applied to assess the effects of heterogeneity among the selected studies. Incoherence and heterogeneity between studies were quantified by I2 index and Cochran's Q test. Publication and population bias was assessed with funnel plots and Egger's regression asymmetry test. All statistical analyses were performed using Stata (version 2.7.2). Results : Seventy-one studies from 21 countries, 5 continents, were included in the present systematic review. The median prevalence of malaria parasitemia among 984 975 asymptomatic healthy blood donors was 10.54%, 5.36%, and 0.38% by microscopy, molecular methods (polymerase chain reaction), and rapid diagnostic tests, respectively. The most commonly detected Plasmodium species was P. falciparum. Conclusions : This systematic review demonstrates that compared with other transfusion-linked infections, that is, HIV, HCV, and HBV, transfusion-transmitted malaria is one of the most significant transfusion-associated infections especially in Sub-Saharan Africa. Future work must aim to understand the clinical significance of transfusion-transmitted malaria in malaria-endemic settings.Publisher PDFPeer reviewe

Trefoil Factor Family in Pre-neoplastic Lesions and Gastric Cancer

Gastric cancer is the fourth most common cancer and the second leading cause of cancer death worldwide. Although the global incidence of gastric cancer has been decreased dramatically in recent decades, north and northwest of Iran have the highest incidence rate of gastric cancer. Whilst the surgical procedures for gastric cancer have been improved, there is no cure for that. The intestinal type of GC results from pre-neoplastic conditions including atrophic gastritis, intestinal metaplasia and dysplasia. Trefoil Factors Family proteins (TFFs) are small and stable molecules secreted by the mammalian gastrointestinal tract. TFFs constitute a family of three peptides (TFF1, TFF2and TFF3) that are widely expressed in a tissue specific manner in the gastrointestinal tract. Variable TFFs expression in gastric cancer and pre-neoplastic lesions has been found. TFF1 has a tumor suppressor activity and inhibits tumorogenesis in gastric cancer. Its expression decreases in gastritis, gastric atrophy, dysplasia, intestinal metaplasia and gastric cancer.TFF2 has a protective effect on gastrointestinal epithelium. As a prognostic factor, TFF2 expression decreases in gastric ulcer, chronic atrophic gastritis and gastric cancer. TFF3 is considered as an oncogenic factor in gastric tissues. Whilst the normal gastric tissues don’t express TFF3, it increases in intestinal metaplasia. Therefore, more studies are necessary to clarify the role of TFFs in GC and pre-neoplastic conditions. This review has focused on elucidating the important role of TFFs in gastric cancer and pre-neoplastic lesions

Health-related quality of life among individuals with long-standing spinal cord injury: a comparative study of veterans and non-veterans

<p>Abstract</p> <p>Background</p> <p>Spinal cord-injured (SCI) patients experience poor health-related quality of life (HRQOL) and they usually report lower HRQOL than the general population or population subgroups in Iran and elsewhere. The aim of this study was to compare HRQOL between veterans and non-veterans with SCI in Iran.</p> <p>Methods</p> <p>This was a cross-sectional study. HRQOL was measured using the 36-item Short Form Health Survey (SF-36). Thirty-nine male veterans and 63 non-veteran males with SCI were included in the study. Regression analyses were applied to determine the variables affecting physical and mental health-related quality of life among the patients.</p> <p>Results</p> <p>The male veterans had a lower HRQOL than the non-veterans with SCI. The differences were significant for all measures except for physical and social functioning. The greatest difference was observed for bodily pain (P = 0.001). The regression analysis results indicated that a longer time since injury was associated (P = 0.01) with better physical health-related quality of life (PCS), while being a veteran (P < 0.001) and having a spinal lesion in the cervical region (P = 0.001) were associated with poorer PCS. Older age (P < 0.001) and higher education (P = 0.01) were associated with better mental health-related quality of life (MCS), while being a veteran and having a spinal lesion in the cervical region (P = 0.02) were associated with poorer MCS.</p> <p>Conclusion</p> <p>The study findings showed that veterans with SCI experienced lower HRQOL than their non-veteran counterparts. A qualitative study is recommended to evaluate why HRQOL was lower in veterans than in non-veterans with SCI although veterans had higher incomes as a result of their pensions and increased access to equipment, and medications. To improve quality of life in both veterans and non-veterans with spinal cord injuries, policy changes or implementation of new interventions may be essential so that veterans could receive additional support (e.g. counseling, recreation therapy, vocational therapy, etc.) and non-veterans could meet their basic needs.</p

The global, regional, and national burden of stomach cancer in 195 countries, 1990-2017 : a systematic analysis for the Global Burden of Disease study 2017

Background: Stomach cancer is a major health problem in many countries. Understanding the current burden of stomach cancer and the differential trends across various locations is essential for formulating effective preventive strategies. We report on the incidence, mortality, and disability-adjusted life-years (DALYs) due to stomach cancer in 195 countries and territories from 21 regions between 1990 and 2017. Methods: Estimates from GBD 2017 were used to analyse the incidence, mortality, and DALYs due to stomach cancer at the global, regional, and national levels. The rates were standardised to the GBD world population and reported per 100 000 population as age-standardised incidence rates, age-standardised death rates, and age-standardised DALY rates. All estimates were generated with 95% uncertainty intervals (UIs). Findings: In 2017, more than 1·22 million (95% UI 1·19–1·25) incident cases of stomach cancer occurred worldwide, and nearly 865 000 people (848 000–885 000) died of stomach cancer, contributing to 19·1 million (18·7–19·6) DALYs. The highest age-standardised incidence rates in 2017 were seen in the high-income Asia Pacific (29·5, 28·2–31·0 per 100 000 population) and east Asia (28·6, 27·3–30·0 per 100 000 population) regions, with nearly half of the global incident cases occurring in China. Compared with 1990, in 2017 more than 356 000 more incident cases of stomach cancer were estimated, leading to nearly 96 000 more deaths. Despite the increase in absolute numbers, the worldwide age-standardised rates of stomach cancer (incidence, deaths, and DALYs) have declined since 1990. The drop in the disease burden was associated with improved Socio-demographic Index. Globally, 38·2% (21·1–57·8) of the age-standardised DALYs were attributable to high-sodium diet in both sexes combined, and 24·5% (20·0–28·9) of the age-standardised DALYs were attributable to smoking in males. Interpretation: Our findings provide insight into the changing burden of stomach cancer, which is useful in planning local strategies and monitoring their progress. To this end, specific local strategies should be tailored to each country's risk factor profile. Beyond the current decline in age-standardised incidence and death rates, a decrease in the absolute number of cases and deaths will be possible if the burden in east Asia, where currently almost half of the incident cases and deaths occur, is further reduced.
