Article ; Online: Continuous Performance Improvement Framework for Sustainable Wastewater Treatment Facilities in Arid Regions

Case of Wadi Rumah in Qassim, Saudi Arabia

2021 Volume 6857

Abstract	In arid regions such as Saudi Arabia, wastewater treatment (WWT) facilities (meeting promulgated standards) need to adapt their continuous performance improvement (CPI) for long-term sustainability. To achieve this, the facilities need to improve their performance to comply with more strict objectives for broader reuse applications of treated effluent. The present research proposes a CPI framework based on performance benchmarking process for the stepwise improvement of WWT facilities. A grey rational analysis water quality index (GWQI) based on exceedance probability was developed. For weights’ estimation of 11 physical, chemical, and biological water quality parameters, the entropy method effectively accommodated the changes in relative importance of the parameters with including additional future reuse applications. For existing effluent reuse scenarios of restricted and unrestricted irrigation, the GWQI values were found consistent with the modified version of the Canadian WQI (CWQI). The indices’ values (ranged between 0 and 100) greater than 80 showed the efficient operation of four WWT plants in the Qassim Region of Saudi Arabia. Two hypothetical CPI scenarios with future reuse applications (fish, livestock drinking, and recreation) showed an overall decline in the average (of four plants) values of the GWQI (97 to 78) and CWQI (85 to 60). CWQI predicted stricter results for the facilities with parameters’ concentrations exceeding the targets with larger margins and was found applicable for the CPI of WWT facilities in arid regions. For existing scenarios, the assessment results suggest the facilities to control and monitor the chlorination practice. For future targets, tertiary treatment needs to be enhanced for desired nutrients and total dissolved solids removal. The proposed CPI framework provides a platform to initiate the performance benchmarking process for WWT facilities at local or regional levels in Saudi Arabia and elsewhere.

Abstract	The aim: The study aims to evaluate the clinical presentation and surgical management of small bowel Crohn's disease (CD) at a tertiary referral center in the Kingdom of Saudi Arabia (KSA). Patients and methods: A retrospective review of the medical records of all patients with the diagnosis of small bowel CD from March 1999 up to December 2003. The records of 28 patients were reviewed for demographic data, clinical presentation, preoperative investigations, indications of surgery, surgical procedures, postoperative complications and follow-up. The final diagnosis of CD was based on paraffin section histopathology reports. Results: The mean age was 34 years, female to male ratio was 1:2.1. The medical treatment was offered to 22 patients in whom the diagnosis of CD was established after investigations or they were known to have CD before admission. Thirteen patients (46.4%) responded to medical treatment, whereas 15 patients (53.6%) required surgery. The indications for surgery were intestinal obstruction (seven patients), right iliac fossa mass lesion of uncertain nature (three patients), enterocutaneous fistula and pelvic collection (one patient), failure of medical treatment (two patients), and acute abdomen (two patients). The surgical procedures carried out were limited right hemicolectomy in ten patients, segmental bowel resection (two patients) and stricturoplasty of the stenosed segment (three patients). Conclusion: Crohn's disease is not uncommon in KSA. It is a disease of young patients, half of patients needed surgery at some stage. Intestinal obstruction remains the most common indication of surgery. The surgery of CD needs a good cooperation between the surgeon, radiologist and gastroenterologist.

Abstract	In arid regions, the groundwater drawdown consistently increases, and even for a constant pumping rate, long-term predictions remain a challenge. The present research applies the modular three-dimensional finite-difference groundwater flow (MODFLOW) model to a unique aquifer facing challenges of undefined boundary conditions. Artificial neural networks (ANN) and adaptive neuro fuzzy inference systems (ANFIS) have also been investigated for predicting groundwater levels in the aquifer. A framework is developed for evaluating the impact of various scenarios of groundwater pumping on aquifer depletion. A new code in MATLAB was written for predictions of aquifer depletion using ANN/ANFIS. The geotechnical, meteorological, and hydrological data, including discharge and groundwater levels from 1980 to 2018 for wells in Qassim, were collected from the ministry concerned. The Nash–Sutcliffe efficiency and mean square error examined the performance of the models. The study found that the existing pumping rates can result in an alarming drawdown of 105 m in the next 50 years. Appropriate water conservation strategies for maintaining the existing pumping rate can reduce the impact on aquifer depletion by 33%.

Abstract	Objective: To determine the long term outcome of cholecystectomy without intraoperative cholangiogram (IOC) in patients recovering from acute gallstone pancreatitis with normal preoperative liver function tests and imaging. Methods: The medical records of all patients who underwent cholecystectomy without IOC for gallstone pancreatitis at King Saud Medical City, Riyadh, Saudi Arabia between January 2005 and December 2009 were studied retrospectively. Patients with severe pancreatitis and those who had preoperative endoscopic retrograde cholangio-pancreatography (ERCP) were excluded from the study. Data on patients' demography, symptoms, laboratory findings, intraoperative and postoperative findings, length of hospital stay, and outpatient follow up were collected and analyzed. Results: A total of 160 patients were treated for acute gallstone pancreatitis. Forty-four patients with preoperative ERCP (n = 39), and severe pancreatitis (n = 5), were excluded. The remaining 116 patients initially underwent conservative treatment followed by cholecystectomy without IOC. All were followed up for an average of 2-4 visits. Five patients (4.3%) were re-admitted with gallstone related bilio-pancreatic complications. They underwent ERCP and CBD stone clearance. Four patients were lost to follow up. The remaining 107 patients have remained asymptomatic 12-55 months after cholecystectomy. Conclusion: The incidence of bilio-pancreatic complications from unsuspected CBD stones in patients of biliary pancreatitis that underwent cholecystectomy without IOC is very low. Therefore, a routine IOC in these patients can be omitted safely.

Abstract	Objective: This observational cross-sectional multicenter study aimed to evaluate the longitudinal impact of the coronavirus disease 2019 (COVID-19) pandemic on neurosurgical practice. Methods: We included 29 participating neurosurgeons in centers from all geographical regions in the Kingdom of Saudi Arabia. The study period, which was between March 5, 2020 and May 20, 2020, was divided into three equal periods to determine the longitudinal effect of COVID-19 measures on neurosurgical practice over time. Results: During the 11-week study period, 474 neurosurgical interventions were performed. The median number of neurosurgical procedures per day was 5.5 (interquartile range [IQR]: 3.5-8). The number of cases declined from 72 in the first week and plateaued at the 30's range in subsequent weeks. The most and least number of performed procedures were oncology (129 [27.2 %]) and functional procedures (6 [1.3 %]), respectively. Emergency (Priority 1) cases were more frequent than non-urgent (Priority 4) cases (178 [37.6 %] vs. 74 [15.6 %], respectively). In our series, there were three positive COVID-19 cases. There was a significant among-period difference in the length of hospital stay, which dropped from a median stay of 7 days (IQR: 4-18) to 6 (IQR: 3-13) to 5 days (IQR: 2-8). There was no significant among-period difference with respect to institution type, complications, or mortality. Conclusion: Our study demonstrated that the COVID-19 pandemic decreased the number of procedures performed in neurosurgery practice. The load of emergency neurosurgery procedures did not change throughout the three periods, which reflects the need to designate ample resources to cover emergencies. Notably, with strict screening for COVID -19 infections, neurosurgical procedures could be safely performed during the early pandemic phase. We recommend to restart performing neurosurgical procedures once the pandemic gets stabilized to avoid possible post pandemic health-care system intolerable overload.

Abstract	Objective: Quantitative documentation of the effects of outbreaks, including the coronavirus disease 2019 (COVID-19) pandemic, is limited in neurosurgery. Our study aimed to evaluate the effects of the COVID-19 pandemic on neurosurgical practice and to determine whether surgical procedures are associated with increased morbidity and mortality. Methods: A multicenter case-control study was conducted, involving patients who underwent neurosurgical intervention in the Kingdom of Saudi Arabia during 2 periods: pre-COVID-19 and during the COVID-19 pandemic. The surgical intervention data evaluated included diagnostic category, case priority, complications, length of hospital stay, and 30-day mortality. Results: A total of 850 procedures were included, 36% during COVID-19. The median number of procedures per day was significantly lower during the COVID-19 period (5.5 cases) than during the pre-COVID-19 period (12 cases; P < 0.0001). Complications, length of hospital stay, and 30-day mortality did not differ during the pandemic. In a multivariate analysis comparing both periods, case priority levels 1 (immediate) (odds ratio [OR], 1.82; 95% confidence interval [CI], 1.24-2.67), 1 (1-24 h) (OR, 1.63; 95% CI, 1.10-2.41), and 4 (OR, 0.28; 95% CI, 0.19-0.42) showed significant differences. Conclusions: During the early phase of the COVID-19 pandemic, the overall number of neurosurgical procedures declined, but the load of emergency procedures remained the same, thus highlighting the need to allocate sufficient resources for emergencies. More importantly, performing neurosurgical procedures during the pandemic in regions with limited effects of the outbreak on the health care system was safe. Our findings may aid in developing guidelines for acute and long-term care during pandemics in surgical subspecialties.
