RESUMEN

In the oil and gas industries, predicting and classifying oil and gas production for hydrocarbon wells is difficult. Most oil and gas companies use reservoir simulation software to predict future oil and gas production and devise optimum field development plans. However, this process costs an immense number of resources and is time consuming. Each reservoir prediction experiment needs tens or hundreds of simulation runs, taking several hours or days to finish. In this paper, we attempt to overcome these issues by creating machine learning and deep learning models to expedite the process of forecasting oil and gas production. The dataset was provided by the leading oil producer, Saudi Aramco. Our approach reduced the time costs to a worst-case of a few minutes. Our study covered eight different ML and DL experiments and achieved its most outstanding R2 scores of 0.96 for XGBoost, 0.97 for ANN, and 0.98 for RNN over the other experiments.

RESUMEN

Background End-of-life care is essential for individuals with advanced illness and their families, providing comfort, symptom control, and dignity in the final year of life. Additionally, physician competence requires the ability to communicate, make decisions, and create relationships in end-of-life care. This study assesses family physicians' knowledge and attitude regarding end-of-life care in Taif, Saudi Arabia. Methods This descriptive cross-sectional study conducted between October and November 2021 assessed the knowledge and attitudes of 163 family physicians in Taif City, Saudi Arabia, regarding end-of-life care. Using a convenient sampling technique, an adapted and validated questionnaire was administered electronically, collecting sociodemographic information and assessing participants' knowledge and attitudes. Data were analyzed using descriptive statistics in Statistical Product and Service Solutions (SPSS, version 28) (IBM SPSS Statistics for Windows, Armonk, NY). Results Findings included that 41.1% of residents believed the patient and family should be informed about diagnoses and prognoses in advanced diseases. At the same time, attitudes varied, with 45.4% agreeing that discussing such information could lead to patient depression and 42.9% believing it held no privilege for patients. Additionally, 57.7% recognized that grief reactions would occur, but patients would eventually adjust, and 44.8% agreed that discussing diagnoses would decrease patient anxiety. However, limited awareness of advance directives was evident, with 12.3% reporting being well aware and 45.4% having never heard of them. There was uncertainty and hesitancy regarding Do Not Attempt Cardiopulmonary Resuscitation (DNACPR) decisions, with 39.9% being well aware and 46% having heard of it without a strong understanding. Conclusion The findings revealed a mixed landscape, with physicians demonstrating awareness of the importance of transparent communication but needing more knowledge in areas such as advance directives and complex decision-making. The study highlighted the need for targeted education to address these gaps and promote a more informed and consistent approach to end-of-life care.

RESUMEN

Background Cerebral palsy (CP) is a chronic disorder of motion, posture, and tone which occurs due to brain insult during the period of brain growth. It is a disabling disorder in both motor and intellectual aspects. Fortunately, CP is a manageable disease that can be managed in part by increasing the knowledge and understanding of the parents. Methodology This cross-sectional, prospective, community-based study aimed to assess the level of parents' knowledge and their attitude toward CP using an electronic questionnaire. The parents' knowledge was classified as good or poor based on an adopted scoring system. The parents' attitude was categorized as positive or negative. Results Our study results showed that good knowledge (those with a score more than 60% of the total score) was noted in 275 (61.1%) participants, whereas 175 of the participants had poor knowledge (38.9%), especially regarding awareness of the diagnosis of CP. Conclusions Most participants had an overall good knowledge of CP although they had insufficient knowledge of some aspects of the disease such as causes, disease course, clinical presentations, diagnosis, and prognosis. Although the results showed a positive attitude concerning playing with a child with CP, unfortunately, there was a negative attitude toward hiring a CP patient and a strongly negative attitude toward marrying a patient with CP.

RESUMEN

INTRODUCTION: There is emerging literature on the decline in adherence to preventive measures against the COVID-19 pandemic, a phenomenon of pandemic fatigue (PF). However, academics and policymakers have debated its existence and consequences. We conducted this study to explore this phenomenon, its existence, determinants, and relation to adherence to COVID-19 preventive measures, and the mediating role of resilience, fear of COVID-19, and electronic health literacy about COVID-19 in this relationship. METHODS: This cross-sectional online study was conducted from April to June 2021 using a convenience sample of 650 Saudi adults from all regions of Saudi Arabia using a reliable questionnaire. A structural equation model (SEM) was used for mediation analysis. RESULTS: The results revealed a moderate level of PF among Saudi adults. Younger patients experienced more PF. Fear of COVID-19 had a non-significant (p=0.127) effect on PF. SEM analysis revealed that both resilience and electronic health literacy significantly (p=0.000) mediated the relationship between PF and adherence to preventive measures, and acted as protective factors. In conclusion, there is evidence that PF exists and negatively affects adherence to preventive measures. CONCLUSION: Policymakers should apply evidence-based programs to increase public resilience, particularly targeting young adults, as the results of the current study shed light on its protective mediating role against PF. Increasing electronic health literacy is an effective strategy for preventing PF through an increase in the perceived effectiveness of preventive measures.

RESUMEN

Context: Immunodeficiency virus infection is a major health crisis. It can spread to other people by transmission of the body fluid. The knowledge about this viral infection can aid in preventing its transmission and help in delivering successful dental care to these patients. Aims: To evaluate the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS)-related knowledge and attitude of dental students and also to compare knowledge and attitude between a student's gender and different clinical levels (second, third vs. fourth to seventh years). Settings and Design: A cross-sectional study was conducted among dental students at the college of dentistry in Umm Al-Qura University in Makkah, KSA. Methods and Material: A validated survey was sent electronically to dental students from the second year to seventh year. The questionnaire contained 12 knowledge and 13 attitude questions about treating HIV/AIDS patients. Descriptive statistics were presented for the knowledge and attitude of the dental students about HIV/AIDS. Also, the knowledge and attitude were compared using t-test in relation to gender and clinical year. Results: The response rate was 65%. The mean and standard deviation (SD) for the knowledge score was 8.32 ± 1.60 out of 12. There was no significant difference between gender and a student's clinical level. In the majority of the attitude questions, more than half of the students had favorable attitude toward HIV/AIDS subjects. Females had more favorable attitude as well as students with more clinical years of experience. Conclusions: Dental students showed acceptable knowledge and positive attitude toward HIV/AIDS patients. Students who were females and with higher clinical years demonstrated better attitude but similar knowledge to males.

RESUMEN

Abdominal pain is a common cause of emergency department visits. It often poses a diagnostic challenge for physicians given the broad spectrum of its possible medical and surgical etiologies. We report the case of a 32-year-old man who presented to the emergency department with a complaint of lower abdominal pain for one week. Abdominal examination revealed suprapubic mass and tenderness. Laboratory investigation revealed elevated leukocyte count and inflammatory markers. An abdominal ultrasound examination showed a collection with poorly defined borders. Additionally, CT demonstrated a soft tissue mass adjacent to the anterior abdominal wall with an upward track to the umbilicus, conferring the diagnosis of a urachal abscess. The patient underwent successful management of the abscess with surgical excision. This case highlights the importance for clinicians to be aware of congenital urachal anomalies since early recognition of the urachal cyst is essential to determine the proper surgical management.

RESUMEN

OBJECTIVES: To estimate the prevalence of intimate partner violence (IPV) among female patients, age 18-60 years, attending primary health care centers (PHCCs) and to measure its determinants, and reporting behavior. METHODS: A cross-sectional study design using validated, translated, and self-administered questionnaire among 497 Saudi female patients attending PHCCs in Taif, Kingdom of Saudi Arabia (KSA) from January to February 2015 was employed. A 2-stage probability sampling was adopted for selection of PHCCs in the first stage, and then participants in the second stage. RESULTS: The estimated prevalence of IPV during the last year was 11.9%. Predictors of IPV related to abused women included divorced status and divorced parents; while those related to abusers (husbands) included widowed parents, exposure to violence in childhood, and alcohol or drugs addiction. Most of the abused wives (56%) talked regarding their IPV to their families, their husbands' families (15.2%), or their friends (11.8%); while only a minority (3.3%) complained to the police or to a judge, and no one reported this to a family physician, or to women protection agency. CONCLUSION: One out of 10 women is a victim of IPV in Taif, KSA. Intimate partner violence is significantly associated with a number of victims and abuser-related psychosocial factors, the detection of which might help screening for individuals at risk.
