General geology and groundwater quality analysis of domestic wells around Kampung Panglima Bayu, Tanah Merah District, Kelantan, Malaysia

The current research project focuses on geological mapping and groundwater quality analysis of domestic wells in and around Kampung Panglima Bayu, in Tanah Merah district, Kelantan. The objective of this research is to produce an updated geological map of the study area at a scale of 1:25000 and to conduct groundwater quality analysis in the research region. Groundwater samples were obtained from 12 domestic wells for the analysis of physicochemical parameters. Temperature, pH, electrical conductivity, turbidity, and total dissolved solids were measured using a multiparameter and turbidity meter on site. Atomic Absorption Spectroscopy (AAS) was used to analyse major trace elements such as potassium, sodium, calcium, magnesium, iron, and manganese, while the titration method was used to analyse bicarbonate and chloride. While spectrophotometer methods were used to analyse fluoride, sulphate, and nitrate. Based on the data analysis of the geology of Kampung Panglima Bayu, three rock units can be found: granite is the most common kind of rock detected in the research region, followed by schist and alluvium. Furthermore, the geomorphology of the study area revealed elevation differences consisting of low land to high hills. The petrographic analysis revealed principle minerals like quartz, alkali feldspar, plagioclase and biotite with the granitic rocks identified as ‘biotite granite porphyry’ due to the high amount of biotite mineral present in the thin section. In addition, the results of our analysis for groundwater quality were compared to World Health Organization (WHO) and Ministry of Health Malaysia (MoHM) standards values. It was observed that 7 of the 12 wells were contaminated because the pH values were below the normal level. Turbidity was high in wells 4, 5, and 11, and sodium ion levels surpassed the standard allowable limit in well 11

Evaluation of a quality improvement intervention to reduce anastomotic leak following right colectomy (EAGLE): pragmatic, batched stepped-wedge, cluster-randomized trial in 64 countries

Background Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. Methods The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. Results A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). Conclusion Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)
