ABSTRACT
The death t toll of the coronavirus disease 2019 (COVID-19) has been considerable. Several risk factors have been linked to mortality due to COVID-19 in hospitals. This study aimed to describe the clinical characteristics of patients who either died from COVID-19 at Dhaka Medical College Hospital in Bangladesh. In this retrospective study, we reviewed the hospital records of patients who died or recovered and tested positive for COVID-19 from May 3 to August 31, 2020. All patients who died during the study period were included in the analysis. A comparison group of patients who survived COVID-19 at the same hospital during the same period was systematically sampled. All available information was retrieved from the records, including demographic, clinical, and laboratory variables. Of the 3115 patients with confirmed COVID-19 during the study period, 282 died.The mean age of patients who died was higher than that of those who survived (56.7 vs 52.6 years). Approximately three-fourths of deceased patients were male. History of smoking (risk ratio 2.3;95% confidence interval: 1.6-3.4), comorbidities (risk ratio: 1.5;95% confidence interal:1.1-2.1), chronic kidney disease (risk ratio: 3.2;95% confidence interval: 1.7-6.25), and ischemic heart disease (risk ratio:1.8;95% confidence interval: 1.1-2.9) were higher among the deceased than among those who survived. Mean C-reactive protein and D-dimer levels [mean (interquartile range), 34 (21-56) vs. 24 (12-48);and D-dimer [1.43 (1-2.4) vs. 0.8 (0.44-1.55)] were higher among those who died than among those who recovered. Older age, male sex, rural residence, history of smoking, and chronic kidney disease were found to be important predictors of mortality. Early hospitalization should be considered for patients with COVID-19 who are older, male, and have chronic kidney disease. Rapid referral to tertiary care facilities is necessary for high-risk patients in rural settings.Copyright © 2023 Hoque MM.
ABSTRACT
This work aims to investigate if social media data, Twitter in particular can be used to detect early warning indicators of COVID-19 pandemic in the United States (US). To demonstrate the viability of this work, English tweets were collected with a hasghtag of COVID-19 related topics ranges from 12th March to end of April 2020. With the help of with N-gram language model and Term Frequency and Inverse Document Frequency (TF-IDF) significant bi-grams such as ("new york”), ("social, distancing”), ("stay, safe”), ("toilet, paper”), ("wash, hand”), ("tested, positive”), (look, like), ("front, line”), ("grocery, store”) etc. are extracted. Our analysis shows that, the natures of the bi-grams directly reflect the characteristics of the infection cases and are almost similarly distributed over different clusters. This study also reveals that, the tweets of ("new york”) increases with ("stay, home”), ("social, distancing”), ("stay, safe”), ("look, like”) and ("tested positive”);and decreases with ("toilet, paper”). Bi-grams with such relationships are recognized as indicators and are validated with the number of infection cases on each day. Results show that, social media data can project the actual scenario of infection curve and able to detect warning indicators once the pandemic is moderately recognized. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
ABSTRACT
Introduction: These new generations of virus “COVID-19” now are not the chines nightmare only however soon as speedy as feasible spread all over the world and grew to be the most existence threating health disorder in the world.

Result: In this study the Iraqi dentists who had participated in it were 169 from all over the country, this descriptive research shows great response of the Iraqi dentists to control infection and reduce the spread of “COVID-19”. Discussion: “COVID-19” is a pandemic disease lead to large changes all over the world, actually dentistry were one of the careers affected by this disease, the dentist during the daily work with dental slow speed handpiece or high speed turbine produce droplets and aerosols which probably are contaminated with the virus “COVID-19”. Conclusion: This study had been showed that the Iraqi dentists have a great commitment toward the society during the period of curfew they had been attend to close their privets clinic in order to reduce the viral spread and control the infection.
ABSTRACT
Aim of the Study: Among undergraduate dental students at Al-Iraqia University after “Covid-19” pandemic, this study was done in order to evaluate the amount of psychological stress between them. Materials and Method: By the use of the General Health Questionnaire (GHQ-12), Psychological stress was evaluated among (305) students who asked to fill completely the supplied questionnaires. Results: The highest level (22.3%) was found at the 1st stage, and generally among female higher than male, (60.9%) scored more than 3 on the (GHQ-12) vs. (38.8%) for male, at p=0.05 which was considered to be statistically significant. Conclusion: Despite the changes in the curriculum and the gradual increase in the number of students. The different sources of stress from the year 2020 were mostly unaltered in our study. To minimize stress among dental students during certain conditions further studies is needed.
