Published: August 2022

Preoperative scoring system to predict difficult laparoscopic cholecystectomy can be regarded as an instrument in the hand of the surgeon, which could help him to prepare for difficult operation, make better preoperative counseling of the patient, and in general, it is a further step towards the safe, modern, surgical practice. The study aimed developing a simple scoring system to predict difficult laparoscopic cholecystectomy preoperatively, which can be used in the daily clinical practice. This is a retrospective study carried out in the 22 May Hospital, Aden, from 1st March 2018 to 29th February 2020. It included 405 patients who had laparoscopic cholecystectomy, and among them, 137 had difficult operation. 10 variables were subjected for multivariate study (binary logistic regression) which had shown association with difficult laparoscopic cholecystectomy on previous univariate analysis. Statistical software SPSS version 17 was used for this purpose and significance level was set to p< 0.05. The necessary predictors (independent factors) which were able to explain the outcome (difficult laparoscopic cholecystectomy) were identified with statistical significance. The effect size of these predictors was rounded and the new values were adopted as scores for each factor. A scoring system was constructed from these factors and their scores. The accuracy of the new score system was tested by the ROC analysis against the same sample.7 predictors were identified. Depending on these variables, the prediction for easy laparoscopic cholecystectomy came true in 87% of cases and the prediction for difficult laparoscopic cholecystectomy came true in 85% of the cases. The returned area under the curve was 0.913, with 95% confidence interval. A score above 2.25 was considered difficult with sensitivity and specificity of 82.25% and 85.8% respectively. There were no cases with score above 9. From the findings of the current study, it could be concluded that the new scoring system had good predictive capability to difficult laparoscopic cholecystectomy and it incorporates simple, few determinants, which could help surgeon and improve patient curative care.

The place of this research was conducted at class IV SDN 42 Pekanbaru, which is located at Adi Sucipto Sidomulyo Timur Street, Marpoyan Damai District, Pekanbaru City, Riau Province. The results showed that the learning difficulty factor for students was an internal factor which was a factor originating from the student itself, stating that the factors that influenced students such as; lack of interest in learning, lack of motivation to learn, lack of self-confidence, lack of concentration while studying, lack of self-awareness of students and lack of understanding of student learning. They have difficulty in learning mathematics. The efforts to overcome these learning difficulties gave an apperception at the beginning of learning, using and explaining the material in a fun way, providing enrichment and self-evaluation of individuals, making improvements and assessing the results of learning tests by giving praise and rewards to students who are able to follow the learning process well. After that, the teacher must close the lesson so that students feel more cared for, because they already feel tired of learning, such as inviting singing and playing.

Published: August 2022

Diabetes Mellitus (DM) type II is a metabolic disorder disease characterized by an increase in blood glucose due to a decrease in insulin secretion by pancreatic beta cells or impaired insulin function (insulin resistance). Blood glucose is a carbohydrate that circulates in the body in the metabolic process. Monitoring blood sugar levels is needed in establishing a diagnosis, especially for Diabetes Mellitus (DM). Blood glucose levels can be checked when the patient is in a fasting condition or it can also be when the patient comes to check, with the results of the examination of blood glucose levels when >200 mg / dl, while for the results of glucose levels during fasting >126 mg / dl.. This type of research is descriptive. A tool to measure blood glucose levels using the Glucometer Method. The time of the study was carried out from January to March at the Islamic Malahayati Medan Hospital’s Laboratory by taking 10 samples. Data collection is carried out by direct examination of blood glucose levels in patients with Diabetes Mellitus at Malahayati Medan Islamic Hospital in March-April 2022.

CHOLESTEROL LEVELS BEFORE AND AFTER CONSUMING SAUSAGE
Authors: Haiti Margareta , Christyawardani Lidwina Septie , Rahmawati Yulia Dewi 
Published: August 2022

Cholesterol is a component of fat forming yellow and in the form of wax which is produced by the liver. One of the foods that can increase cholesterol levels is meat sausage. These food ingredients, if consumed in excess amounts, will increase fat levels in the body, which in turn will increase total cholesterol levels in the blood (hypercholesterolemia). In this millennial era, many foods are produced fast using raw materials from processed meat, one of which is sausage. Sausage is one of the foods that are high in fat, so there will be an increase in fat levels in the body when a person consumes 50 grams of sausage (half a portion). Methods: This research uses analytic / inferential research, namely pre-experiment. There were 20 subjects used.The average (mean) blood cholesterol level before consuming sausage was 203.51 mg / dL and the mean (mean) blood cholesterol level after consuming sausage was 207.67 mg / dL. Furthermore, the results obtained after statistical testing using the paired T-Test, namely p value = 0.056, meaning that there was no significant difference in cholesterol levels before and 2 hours after consuming sausages.In this study it can be concluded that there is no significant difference in cholesterol levels before and 2 hours after consuming 75 grams of sausage (1 serving).

Abstract. The sources and abundance of ice-nucleating particles (INPs) that initiate cloud ice formation remain understudied, especially in the Southern Hemisphere. In this study, we present INP measurements taken close to Punta Arenas, Chile, at the southernmost tip of South America from May 2019 to March 2020, during the Dynamics, Aerosol, Cloud, And Precipitation Observations in the Pristine Environment of the Southern Ocean (DACAPO-PESO) campaign. The highest ice nucleation temperature was observed at −3 ∘C, and from this temperature down to ∼-10 ∘C, a sharp increase of INP number concentration (NINP) was observed. Heating of the samples revealed that roughly 90 % and 80 % of INPs are proteinaceous-based biogenic particles at >-10 and −15 ∘C, respectively. The NINP at Punta Arenas is much higher than that in the Southern Ocean, but it is comparable with an agricultural area in Argentina and forestry environment in the US. Ice active surface site density (ns) is much higher than that for marine aerosol in the Southern Ocean, but comparable to English fertile soil dust. Parameterization based on particle number concentration in the size range larger than 500 nm (N>500 nm) from the global average (DeMott et al., 2010) overestimates the measured INP, but the parameterization representing biological particles from a forestry environment (Tobo et al., 2013) yields NINP comparable to this study. No clear seasonal variation of NINP was observed. High precipitation is one of the most important meteorological parameters to enhance the NINP in both cold and warm seasons. A comparison of data from in situ and lidar measurements showed good agreement for concentrations of large aerosol particles (>500 nm) when assuming continental conditions for retrieval of the lidar data, suggesting that these particles were well mixed within the planetary boundary layer (PBL). This corroborates the continental origin of these particles, consistent with the results from our INP source analysis. Overall, we suggest that a high NINP of biogenic INPs originated from terrestrial sources and were added to the marine air masses during the overflow of a maximum of roughly 150 km of land before arriving at the measurement station.
