Gastric cancer is one of the most common malignancies affecting gastrointestinal tract. It a multifactorial illness, both genetic and environmental factors involving in etiology. A wide variation in the incidence of gastric cancer in different geographical regions. Endoscopy is the most sensitive and specific method for the diagnosis. The aims of this study is to describe the distribution rate of gastric cancer in AL-Diwaniyah province in Iraq in correlation with the patients age, sex and the histopathological types of gastric cancer. From about (4078) patients who underwent gastroscopy for different indications at AL-Diwaniyah gastroenterology and hepatology center in Iraq during the period between November 2015 and April 2019, (76) patients were founded to have gastric cancer by documented histopathological study of tissue biopsy. Gastric cancer distribution was about (1.8%). Males are affected more than females in a ratio of (1.37:1). Out of (76) total number of patients with gastric cancer ;(69) patients (90.79%) having gastric adenocarcinoma ( most common type) with male to female ratio of (1.46:1). (5) Patients (6.58%) having gastrointestinal stromal tumors (GIST) and (2) patients ( 2.63%) having lymphoma. In patients with adenocarcinoma,(12) patients (17.39%) were less than (40 years) of age, (31) patients (44.93%) were between (40-60 years) and (26) patients (37.68%) were older than (60 years). The intestinal-type adenocarcinoma was the most common histopathological type (63.77%), followed by diffuse type (30.43%), mixed (4.35%) and mucinous(1.45%). Gastric cancer incidence is increasing with advance age; it still a public health and challenging problem. Mass screening or surveillance programs is the best method for the detection and diagnosis of gastric cancer at an early stage.

Published: October 2019

Pharmacovigilance promotes the safe and effective use of medicines and thereby optimizes the treatment quality. However, lack of awareness among community pharmacists towards pharmacovigilance decreases the proportion of adverse drug reactions reported and impairs the signal detection process. Hence this study was designed to assess and promote the awareness and attitude of community pharmacists towards pharmacovigilance. This educational interventional study was carried out with 102 community pharmacists across Chennai. A pre-validated three domain-containing questionnaire, 20 items was used to assess the knowledge, attitude and practice before and after the educational intervention. Knowledge, attitude and practices of community pharmacists towards pharmacovigilance was significantly increased after the educational intervention (P<0.05, 95%CI). Median difference in an overall score of knowledge and practice was observed to be 4 and 4.5, respectively. Though the frequency of ADR reporting was not found to be greatly increased in our study, mass educational programs with adequate sampling intervals are needed to strengthen the signal generation process.

Published: October 2019

Evaluation of people at increased risk like first degree relatives of type 2 diabetes mellitus (FDRDM) may be useful to reduce the risk of disease progression, development, early intervention, and to take precautionary measures. By considering the multifactorial pathophysiological changes of D.M., we have examined the body fat distribution, cardiorespiratory fitness, and lipid profile of FDRDM. Similar age, height, waist-hip ratio (WHR) in both groups, significantly higher body mass index (BMI) in FDRDM, was observed in our study. Percentage body fat and blood glucose levels in fasting were elevated considerably, and 12 min walk distance was low in FDRDM. Visceral fat was slightly high, but it was not statistically significant. In FDRDM, High-density lipoproteins (HDL) were less but not statistically significant. Significantly higher levels of Total cholesterol (T.C.), triglycerides (TGL), low-density lipoproteins (LDL), and very-low-density lipoproteins (VLDL) were seen high in FDRDM when compared to controls. Higher body fat percentage reduced cardiorespiratory function and abnormal lipid profile in FDRDM may lead to the development of severe cardiovascular events and necessitates lifestyle modification at early phases of disease development.

Published: October 2019

Training of cadets-air traffic controllers and cadets-pilots is an integral part of the training, which allows you to form the skills of quick and correct decision-making in different types of situations. For the air traffic controller, these are exercises to solve conflict situations with aircraft in the area of their responsibility, solving problems in normal flight conditions, in unfavorable atmospheric conditions and in the non-routine situations in flight. For the pilots, solutions to the problems are reduced to the rapid decisionmaking on aircraft control in normal flight conditions, adverse atmospheric conditions and non-routine situations in flight. As you know, the work of air traffic controllers is associated with the work of pilots, but training in educational institutions takes place separately, resulting in gaps in knowledge of the specifics of the adjacent specialty, and, eventually, leads to errors. Optimization of the educational process is currently an urgent task. The program of joint training can act as an optimization tool. The program enables you to collaboratively practice the skills of fast decision-making, clearly to learn the specifics of the related specialties that will allow you to create a complete picture of the air situation. The program of joint training implies the joint operational logic simulator that combines two simulators. For the air traffic controller, this is a separate airspace area in the form of a sector, for the pilot it is the cockpit. Thus, the solution to the problems occurs sequentially from the air traffic controller to the pilot and vice versa, and the controller has the ability to observe the algorithm of the pilot's actions, and the pilot is able to monitor the algorithm of the controller's actions.

Published: October 2019

Vaname shrimp is one of the most profitable export commodities in Indonesia. However, the shrimp meat undergoes rapid quality degradation when shipped without any preservatives. This is an issue since the preservatives commonly found on the market are formalin-based. This study aims to discover a natural preservative solution by utilizing microbes. The objective of the study is to discover natural preservatives made of symbiont microbe in sea cucumber's intestinal organ by antimicrobial activity screening. Sea cucumber samples were collected from Bandengan waters of Jepara. There are 3 symbiotic microbe form intestinal cucumber that can inhibit the growth from Bacillus cereus and Pseudomonas aeruginosa. These three microbes are Listeria sp., Staphylococcus sp., and Rothia sp. Consequently, tested microbial samples were prepared into a consortium microbe and were tested further as a preservative agent for shrimp with a positive control parameter (cooling). The observations conducted in this study include organoleptic properties, acidity, total colony, proximate test (protein, water, ash, fat, and carbohydrate contents), and Total Volatile Base-Nitrogen (TVBN). The results found 3 active isolates are synergic one to each other as a bacterial consortium. Acidity test of sample extract treatment measured a pH of 7.44, compared to the non-treatment result of 7.14. Organoleptic test results of the shrimp indicated that the shrimp was acceptable for consumption. Proximate test of the treatment did not show a significant difference compared to the positive control treatment. Total colony and TVBN test on treated samples resulted in 48 x 105 CFU/ml and 39.62 mgN% respectively, whereas a similar test on non-treatment sample showed 119 x 105 CFU/ml and 45.31 mgN% respectively. It was concluded that the extract of sea cucumber symbiont microbe consortium showed potency in preventing meat quality degradation in shrimp, although treatment by freezing still produces a better result.

Published: October 2019

Shorea is a genus of the Dipterocarpaceae family which shows high economic and ecological values. Currently, market demand for wood is still met from natural forests that are degrading due to over exploitation. The degraded forests are included in the rehabilitation program that require significant number of planting stocks, mainly from seedlings or wildlings. Correct species identification of planting stocks, particularly wildlings, is an important first step in planting activities and it is relevant with Shorea spp planting stocks due to leaf morphology traits. This study was aimed to examine the traits of leaf morphology of four Shorea species for easy field identification. Samples were taken from five trees for each species. Morphological trait identification was conducted by leaf observation and measurement. The results showed that all four species had the same apex shape. Six of the twelve morphological characteristic of the variable character can influence the morphological characteristics of the leaves, namely the roving leaf, leaf area, leaf length, aspect ratio, form factorand perimeter ratio of diameter. S. leprosula is similar to S. parvifolia, while S. ovalis is similar to S. guiso. Shorea leaf character S. parvifolia differentiated from S. leprosula, while Shorea ovalis similar to Shorea guiso. The LP variable (length from the base of the leaf to the widest point of the leaf) is a variable that can be used as aleaf morphological characteristic of the four Shorea which are compared because each one has a different value. S. ovalis has the highest LP value, followed by S. guiso and S. leprosula, while S. parvifolia has the lowest LP value. Keywords: apex shape, identification, leaf morphology traits, Shorea
