An Evaluation of the National Early Warning Score 2 and the Laboratory Data Decision Tree Early Warning Score in Predicting Mortality in Geriatric Patients

BACKGROUND

Due to the high rate of geriatric patient visits, scoring systems are needed to predict increasing mortality rates.

OBJECTIVE

In this study, we aimed to investigate the in-hospital mortality prediction power of the National Early Warning Score 2 (NEWS2) and the Laboratory Data Decision Tree Early Warning Score (LDT-EWS), which consists of frequently performed laboratory parameters.

METHODS

We retrospectively analyzed 651 geriatric patients who visited the emergency department (ED), were not discharged on the same day from ED, and were hospitalized. The patients were categorized according to their in-hospital mortality status. The NEWS2 and LDT-EWS values of these patients were calculated and compared on the basis of deceased and living patients.

RESULTS

Median (interquartile range [IQR]) NEWS2 and LDT-EWS values of the 127 patients who died were found to be statistically significantly higher than those of the patients who survived (NEWS2: 5 [3-8] vs. 3 [1-5]; p < 0.001; LDT-EWS: 8 [7-10] vs. 6 [5-8]; p < 0.001). In the receiver operating characteristic curve analysis, the NEWS2, LDT-EWS, and NEWS2+LDT-EWS-formed by the sum of the two scoring systems-resulted in 0.717, 0.705, and 0.775 area under curve values, respectively.

CONCLUSIONS

The NEWS2 and LDT-EWS were found to be valuable for predicting in-hospital mortality in geriatric patients. The power of the NEWS2 to predict in-hospital mortality increased when used with the LDT-EWS.

Determining the Mental Images of Fourth Grade Private and Public School Students for Science Learning Environments by Drawing Technique

The study aims to examine fourth-grade private and public-school students’ images of the science learning environment using their drawings. The survey was conducted in the 2017-2018 academic year, and a descriptive survey model was used. Participant group of this study consist of 357 fourth-grade students. In this study, data were collected by drawing technique. Content analysis, percentage, frequency, and Chi-Square test of independence were used in data analysis. Regarding the study results, although the learning environment in both schools consists of traditional classrooms and laboratories, differences were observed in student drawings according to school type (public-private). The private school students use the laboratory in science lessons, whereas the students in the public school use the teacher's desk as the experiment table. Another significant result of the study is that public-school students' priority is understanding the topic. In contrast, private school students assign more importance to the materials. Regarding the independence test results, Founding student behavior, teacher behavior, teacher position, and teaching method to differ in student images according to school type. But no found a significant difference between the place theme images of public school and private school students

Tobacco Containing Scenes in Some Selected Turkish Movies Released Between 1992 and 2016

OBJECTIVE

Movies are among the most widely used media for advertising, promotional, and sponsorship activities of the tobacco industry, and the industry has been making huge investments in this sector for many years. In this study, the effects of movie scenes depicting the use of tobacco products, and the possible effects of the laws governing such scenes, were examined.

MATERIAL AND METHODS

The sample of the study consisted of 50 films, the first 2 of which were the most watched each year, between the years 1992 and 2016, according to the data of the Center for Turkish Cinema Studies and the boxofficeturkiye.com websites. The scenes depicting the use of tobacco products were analyzed using the data collection form developed by the researchers. Each movie was evaluated separately by 2 researchers.

RESULTS

A tobacco product was used in 82% of the 50 films watched. Men (87%), individuals between the ages of 25 and 64 (78.0%), and leading actors (40%) used more tobacco products, and the most frequently used product was the cigarette (93.1%). The number andduration of scenes containing tobacco was greater by 1.6 times before the first law was passed, and between the passage of the first law and the passage of the second law (P > .05, P > .05). The number and duration of the scenes decreased between the passage of the first and the second laws and after the second law was passed, by 3.6 and 5.3 times, respectively (P < .05, P < .05).

CONCLUSION

Consistent and comprehensive tobacco control policies have been effective in reducing the number of scenes that contain tobacco in the movies produced in Turkey. A comprehensive and multidisciplinary approach is required to overcome the tobacco industry's impact on cinema.

The Effect of Anterior Chamber Maintainer on Anterior Chamber Contamination

PURPOSE

To evaluate the effect of anterior chamber continuous infusion maintainer system on the contamination of anterior chamber in phacoemulsification surgery.

METHODS

Clear corneal phacoemulsification surgery was performed in 132 eyes of 132 randomly selected patients with cataract who were divided into two groups of 66 eyes according to the use of an anterior chamber maintainer (ACM) system. The fluid specimens were taken from anterior chamber in the beginning and at the end of the surgery. They were transferred under anaerobic conditions and investigated by culturing onto blood agar and thiogluconate broth media. Differences between the two groups with respect to contamination of the specimens were investigated.

RESULTS

The mean age of the group undergoing surgery without a maintainer system (Group A) was 63 +/- 10 years (min = 41, max = 80) versus 59 +/- 10 years (min = 33, max = 80) in the other group (Group B) in which the maintainer was used during surgery. In the postoperative specimen, Micrococcus species were isolated from one eye (1.5%) in Group A and S. pyogenes in one eye (1.5%) from Group B. Mean follow-up interval was 12 +/- 6 (min = 4, max = 28) months.

CONCLUSIONS

The use of ACM system in clear corneal phacoemulsification surgery carries no additional risks as far as contamination is concerned.

Seasonally gross alpha and beta activity concentration in surface water and sediments in Sır Dam Pond

Seasonally gross alpha–beta activities were measured in surface water and sediments in Sır Dam Pond (Kahramanmaras, Turkey). Six sampling sites were pre-defined in different locations of the Sır Dam Pond. Preliminary studies of gross-α and gross-β activities in the surface water and deep sediments were determined. The results obtained from the determination of the activity indicate that gross-α and gross-β activities were ranging from 0,007 ± 0,005 to 0,077 ± 0,006 Bq/l and from 0,028 ± 0,006 to 0,189 ± 0,009 Bq/l for the surface water and from 0,001 ± 0.001 to 0,229 ± 0,032 Bq/g and from 0,144 ± 0,026 to 0,419 ± 0,033 Bq/g for deep sediment, respectively.

Concentrations of heavy metal and radioactivity in surface water and sediment of Hazar Lake (Elaziğ, Turkey)

Concentration of heavy metals and natural gross radioactivity were measured in the surface water and sediment of Hazar Lake (Elaziğ, Turkey). Eight sampling sites were pre-defined in different locations of the lake. A preliminary study on heavy metals (Zn, Fe, Mn, Ni, Cu, Cr, Co and Pb), major elements (Na, K, Ca, Mg) concentrations and natural radioactivity related to 226Ra, gross-alpha and gross-beta radiations in the surface water and deep sediments were determined. The obtained results showed that, in general, the heavy metals (Zn, Fe, Mn, Ni, Cu and Pb) and major elements (Na, K, Ca, Mg) concentrations in water did not exceed WHO (World Health Organization, 1999), EC (Europe Community, 1998), EPA (Environment Protection Agency, 2002) and TSE-266 (Turkish Standard, 1997) guidelines. Generally, heavy metals and major elements concentration of the sediments were found decrease in sequence of Fe>Mg>Ca>Mn>Zn>Ni>Cr>Cu>Co>Pb. The results of this study indicated that a general absence of serious pollution in the Hazar Lake. The results obtained from the radioactivity determination indicate that the surface water radioactivity concentration of 226Ra, gross-alpha and gross-beta were ranging from 0.52+/-0.02 to 2.02+/-0.06 Bq/l and from 0.65+/-0.03 to 2.52+/-0.07 Bq/l and from 0.01+/-0.01 to 0.14+/-0.01 Bq/l, respectively. Deep sediment radioactivity concentrations of 226Ra is ranging from 0.07+/-0.03 to 0.32+/-0.07 Bq/g.
