The problem that is often encountered in clean water is that the quality of the water, both groundwater and river water used by the community, does not meet the requirements of healthy clean water. This study aims to determine the effectiveness of activated charcoal from bamboo on pH and decrease the hardness level of dug well water in the village of Lampoh Keude, Aceh Besar. This study used a Quasi-experimental method, water obtained from residents' wells was processed using the filtration and adsorption method, the filtration media was made using media with a volume of 20 liters which had been modified using sand with a thickness of 10 cm, 10 cm of palm fiber, and 10 gravel cm. The highest pH increase test results occurred in TH III AB media where the resulting pH was 7.7 ± 0.01 compared to 4.5 before processing. The same thing also happened to a decrease in the hardness level of residents' well water, where the thickness of the charcoal and the length of contact time greatly affected the test results, from the results of the 3 existing media tests, the best results were obtained by TH III AB media with a contact time of 30 minutes where the level The hardness obtained was 279 ± 3.46 mg/L or a decrease of 47.1% from the initial hardness level of well waste. There is an increase in the pH value of well water after processing, and that the use of bamboo charcoal can also reduce the hardness level of well water

Argumentation skill is a part of the critical thinking ability needed by students to be successful in learning science. This study aims to understand the effect of the implementation of 4 Step Jigsaw (4SJ) and original jigsaw learning models in rehearsing the argumentation skill of junior high school students in the concept of plant structure and function. This argumentation skill is further investigated in the lens of varied students’ level of confidence. This study employs the quasi-experiment factorial 2 x 2 with the type of Pretest Posttest Nonequivalent Control Group design. The population was the students from grade 8 SMPN 17 Batanghari with total of 106 students, consisted of 44 males and 62 females. Some 53 students were recruited to be the sample grouped into 2 classes, i.e., the class 8A as the class 4SJ and the class 8C as the original jigsaw class. Data were collected using a valid self-confidence questionnaire and a valid pretest and a posttest in argumentation. Data were analyzed using two-way Anova test and statistics descriptive techniques. The results show that the 4SJ students have higher average of argumentation skill score (77.77) than the jigsaw students (71.17). It was also factual that students with better self-confidence also have higher average of argumentation skill score (75.13) than   those with lower self-confidence (73.81). The results of two-way Anova test emphasize that there is an effect of the utilization of the models on the students’ argumentation skill. There is also an effect of the students’ self-confidence on the students’ argumentation skill. Even though it was very weak, it can be said that there is a potential for the learning models and the self-confidence to have an interaction in causing the growth of the students’ argumentation skill. It can be concluded that appropriate learning models and suitable self-confidence may affect students’ learning outcomes.

Objective: To find the association between the patters of thrombocytopenia with the timings and patterns of plasma leakage in patients presenting with dengue hemorrhagic fever (DHF) during the dengue epidemic of 2019, in Rawalpindi city. Study Design: Cross-sectional study. Setting: Department of Medicine, District Headquarter Hospital, Rawalpindi, Pakistan. Period: August to November 2019. Material & Methods: In which patients who were labelled and managed as DHF on the basis of clinical presentation, positive serology and ultrasonic evidence of plasma leakage were included. Demographic profile, clinical features with duration of illness, laboratory investigations including serological markers (NS1, IgG and IgG) and ultrasonic findings were recorded on a self-structured performa and data was analyzed using SPSS v23.0. Results: Two hundred and ninety five patients with DHF were enrolled in the study. There were 2012 males and 83 females (male to female ration of 2.5:1). Mean age of all participants was 32.83 years. 50.5% of the cases were primary infection (based on serology), whereas 38.3% were secondary infection and 11.2% were triple negative infection. In 81.1% of the cases, plasma leakage occurred on the 4th to 7th day of illness. In these cases, platelet count was <40,000 cells/mm³ in 13.6% cases, between 40,000 cells/mm³ - 80,000 cells/mm³ in 50.8% cases and greater than 80,000 cells/mm³ in 35.5% cases. Amongst the 17.8% of cases where plasma leakage occurred between 8th to 10th days, 56.6% had platelet count greater than 80,000 cells/mm³, 22.6% has platelet count between 40,000 cells/mm³- 80,000 cells/mm³ and 20.8% had platelet count of less than 40,000 cells/mm³. Conclusion: Most people had plasma leakage at day 4-7 of illness, so needed more critical monitoring and admission at 4th to 7th day of illness, plasma leakage was observed more commonly in primary as compared to secondary infections and mostly at the day of leakage, platelet count was between 40,000 cells/mm³- 80,000 cells/mm³. Strict monitoring is required from the 4th day of illness to detect early signs of leakage to decrease the mortality and complications by dengue infection.

Objective: To determine the effect of orthodontic banding on gingival health of first permanent molars. Study Design: Quasi Experimental. Setting: Khyber College of Dentistry, Peshawar. Period: 15th December 2020 to 15th June 2021. Material & Methods: This study was conducted on 70 patients by non-probability consecutive sampling technique. Both genders, adult (age 18-40 years) needing orthodontic fixed treatment and having all first permanent molars were included. Patients with medications and medical conditions affecting gingival health and history of periodontal disease were excluded. The gingival health was assessed using gingival and plaque indices before and six months after banding of molars. Paired t test was used for comparing the gingival and plaque indices before and six months of treatment. Results: The mean age was 27±10.12 years. The males were 29(41.42%) and female were 41(58.58%). The mean gingival index score was 1.09±1.10 before banding and was 1.87±1.63 after six months and was statistically significant (p=0.001). Similarly the change in plaque index was very highly statistically significant (p<0.001). Both gingival (p=0.02) and plaque (p=0.04) indices were statistically significantly aggravated in those not brushing their teeth. Similarly the patients who are not using any sort of interdental aids had significantly increased plaque (p=0.01) and gingival (p=0.03) indices. Conclusion: Orthodontic banding can adversely affect the gingival health in patients receiving fixed appliance treatment. Lack of proper oral hygiene maintenance further aggravates poor gingival health.

Objective: To find out the incidence, characteristics and laboratory parameters of epistaxis in children with β-thalassemia major visiting a tertiary healthcare facility of South Punjab, Pakistan. Study Design: Retrospective study. Setting: Department of Hematological Disorder, Thalassemia and Bone Marrow Transplantation Centre, and Department of Biochemistry, Bahawal Victoria Hospital, Quaid e Azam Medical College, Bahawalpur, Pakistan. Period: January 2021 to November 2022. Material & Methods: The hospital record of children of both genders aged from 2 to 18 years of age with blood transfusion dependent β-thalassemia was analyzed. Children reporting at least 1 episode of epistaxis in the preceding period were included in the final analysis to find out the incidence, characteristics and laboratory findings of children presenting with of epistaxis. Results: Out of 3772 children with β-thalassemia major, 85 reported at least 1 episode of epistaxis showing the incidence of epistaxis as 22.5/1,000 cases of β-thalassemia major. The mean age of the children at the time of enrollment and at the time of diagnosis of thalassemia was 9.93±3.48 years and 1.23±1.26 years respectively. The mean monthly frequency of blood transfusion was 1.71±0.75 blood transfusions per month. The mean monthly epistaxis frequency was reported to be 2.35±1.71 while 59 (69.4%) children had 2 or more than 2 monthly episodes of epistaxis. The mean serum ferritin level was noted to be 4058±2173 ng/ml. Ultrasonography findings revealed mean spleen size to be 9.25±5.80 cm. Conclusion: The incidence of epistaxis episodes among children with β-thalassemia was very high. Chronic iron-overload seemed to be common abnormality among children with β-thalassemia that should be addressed to potentially reduce the risk of epistaxis among these children.
