    Elbanan WK, Fathy SA, Ibrahim RA, Hegazy MGA
    Trop Biomed, 2020 Dec 01;37(4):1093-1104.
    PMID: 33612761 DOI: 10.47665/tb.37.4.1093
    Hepatitis C virus (HCV) infection in Egypt is the most serious health problem. Identifying HCV-positive persons at high risk of early complications can help prioritize treatment decisions. Recently, attention has been directed to non-invasive, accurate alternatives using serum biochemical markers. The transforming growth factor β 1/interleukins pathway plays an important role in the process of cell injury and inflammation. Thus, TGF-β1 and IL-17 were assessed in serum of chronic HCV patients with correlation to hepatic inflammatory and fibrotic status. The quantitative serum levels of TGF-β1 and IL-17 were analyzed among chronic hepatitis C (CHC) patients (n=75) and normal control (NC) subjects (n=15). Disease severity in patients was assessed using the Child-Pugh scores and METAVIR. Serum levels of TGF-β1 and IL-17 were significantly increased in HCV patients compared to control group. Furthermore, the levels of TGF-β1 and Il-17 were positively correlated to serum transaminases and alpha-fetoprotein and they were negatively correlated with serum albumin and platelets. Additionally, the serum levels of TGF-β1 and Il-17 were associated with inflammation grades and stages of liver fibrosis. TGF-β1 and IL-17 may be hopeful serum biomarkers concerned in the progression of liver inflammation and fibrosis accompanying chronic HCV infection. Therefore, they could be used in the future as targets for anti-fibrotic therapy of chronic HCV to ameliorate the disease progress.

    J Obstet Gynaecol Res, 2017 Mar;43(3):543-550.
    PMID: 28160508 DOI: 10.1111/jog.13234
    AIM: The aim of this study was to evaluate the management outcomes of advanced pelvic organ prolapse (POP) in nulliparous women.

    METHODS: Eight nulliparous women diagnosed with POP ≥ stage 3 between January 2005 and August 2013, according to the Pelvic Organ Quantification System (POPQ), were reviewed. Seven were managed surgically and one was managed with pessary. Primary outcome was surgical objective cure (POP-Q ≤ 1) and subjective cure, defined as negative response to questions 2 and 3 on Pelvic Organ Prolapse Distress Inventory 6. Secondary outcomes were complications, symptoms' severity and quality of life according to validated questionnaires.

    RESULTS: A total of 1275 prolapse patients with POP-Q ≥ stage 3 were managed surgically, among whom seven (0.55%) were nulliparous. Each woman had at least one risk factor associated with POP. Risk factors identified were history of pelvic trauma, obesity, menopause, chronic cough, hard physical labor and constipation. Five patients underwent surgical correction (vaginal hysterectomy with sacrospinous fixation) with mesh (Perigee, n = 3; Avaulta, n = 2). Two patients had uterine preservation without mesh (hysteropexy with sacrospinous ligament fixation). One patient preferred treatment with pessary. The total cure rate (objective and subjective cure rates) was 86% after surgical reconstructive surgery.

    CONCLUSION: Management of nulliparous advanced POP poses significant challenges with regard to uterine preservation, future pregnancy and childbirth. Conservative management with pessary insertion should be offered followed by surgical correction. Reconstructive surgery with mesh may improve prolapse symptoms objectively and subjectively.

    PMID: 34508377
    INTRODUCTION: Antibiotic resistance is a burgeoning problem worldwide. The trend of bacterial resistance has increased over the past decade in which more common bacteria are becoming resistant to almost all the antibiotics currently in use, posing a threat to humans and even livestock.

    METHODS: The databases used to search for the relevant articles for this review include PubMed, Science Direct, and Scopus. The following keywords were used in the search: Antimicrobial resistance, Malaysian action plan, antibioticresistant bacteria, and Malaysian National Surveillance on Antimicrobial Resistance (NSAR). The relevant articles published in English were considered.

    RESULTS: The antibiotic-resistant bacteria highlighted in this review showed an increase in resistance patterns to the majority of the antibiotics tested. The Malaysian government has come up with an action plan to create public awareness and to educate them regarding the health implications of antibiotic resistance.

    CONCLUSION: Antimicrobial resistance in Malaysia continues to escalate and is attributed to the overuse and misuse of antibiotics in various fields. As this crisis impacts the health of both humans and animals, therefore a joined continuous effort from all sectors is warranted to reduce the spread and minimize its development.

    PMID: 32860377
    INTRODUCTION: The susceptibility patterns of anaerobes are becoming less predictable due to the emergence of anaerobic resistance trends to antibiotics; hence increasing the importance of the isolation and antimicrobial susceptibility testing of anaerobes.

    MATERIALS AND METHODS: This study investigated the isolation of anaerobes from the clinical specimens of Hospital Sungai Buloh, Malaysia, from January 2015 to December 2015. All isolates were identified using the API 20A system (bioMérieux, France). Antimicrobial susceptibility testing was performed using the E-test (bioMérieux, France).

    RESULTS: The proportion of obligate anaerobes isolated from the clinical specimens was 0.83%. The Gram-positive anaerobes were most susceptible to vancomycin and imipenem, showing 100% sensitivity to these antimicrobials, followed by clindamycin (86.3%), penicillin (76.7%), and metronidazole (48.9%). Meanwhile, Gram-negative anaerobes were most susceptible to metronidazole (96%) followed by imipenem (89%), clindamycin (79%), and ampicillin (32%). The present study also showed that 3 out of 12 Bacteroides fragilis isolates were resistant to imipenem.

    CONCLUSION: This study demonstrated the differences in the susceptibility patterns of anaerobes towards commonly used antimicrobials for the treatment of anaerobic infections. In summary, continuous monitoring of antimicrobial resistance trends among anaerobes is needed to ensure the appropriateness of treatment.

  5. Fulltext A Review of Staphylococcal Cassette Chromosome mec (SCCmec) Types in Coagulase-Negative Staphylococci (CoNS) Species
    Saber H, Jasni AS, Jamaluddin TZMT, Ibrahim R
    Malays J Med Sci, 2017 Oct;24(5):7-18.
    PMID: 29386968 MyJurnal DOI: 10.21315/mjms2017.24.5.2
    Coagulase-negative staphylococci (CoNS) are considered low pathogenic organisms. However, they are progressively causing more serious infections with time because they have adapted well to various antibiotics owing to their ability to form biofilms. Few studies have been conducted on CoNS in both, hospital and community-acquired settings, especially in Malaysia. Thus, it is important to study their species and gene distributions. A mobile genetic element, staphylococcal cassette chromosome mec (SCCmec), plays an important role in staphylococci pathogenesis. Among CoNS, SCCmec has been studied less frequently than Staphylococcus aureus (coagulase-positive staphylococci). A recent study (8) conducted in Malaysia successfully detected SCCmec type I to VIII as well as several new combination patterns in CoNS species, particularly Staphylococcus epidermidis. However, data are still limited, and further research is warranted. This paper provides a review on SCCmec types among CoNS species.

    Sarcoidosis is a disease that involves multiple organs, including the cardiovascular system. While cardiac sarcoidosis has been increasingly recognized, the impact of sarcoidosis on atrial fibrillation (AF) is not well established. This study aimed to analyze the impact of sarcoidosis on in-hospital outcomes among patients who were admitted for a primary diagnosis of AF. Using the all-payer, nationally representative Nationwide Readmissions Database, our study included patients aged ≥18 years who were admitted for AF between 2017-2020. We stratified the cohort into two groups depending on the presence of sarcoidosis diagnosis. The in-hospital outcomes were assessed between the two groups via propensity score analysis. A total of 1031 (0.27%) AF patients with sarcoidosis and 387,380 (99.73%) AF patients without sarcoidosis were identified in our analysis. Our propensity score analysis of 1031 (50%) patients with AF and sarcoidosis and 1031 (50%) patients with AF but without sarcoidosis revealed comparable outcomes in early mortality (1.55% vs. 1.55%, P = 1.000), prolonged hospital stay (9.51% vs. 9.70%, P = .874), non-home discharge (7.95% vs. 9.89%, P = .108), and 30-day readmission (13.29% vs. 13.69%, P = .797) between the two groups. The cumulative cost of hospitalization was also similar in both groups ($12,632.25 vs. $12,532.63, P = .839). The in-hospital adverse event rates were comparable in both groups. Sarcoidosis is not a risk factor for poorer in-hospital outcomes following AF admission. These findings provide valuable insights into the effectiveness of the current guideline for AF management in patients with concomitant sarcoidosis and AF.

    Taiwan J Obstet Gynecol, 2018 Apr;57(2):311-314.
    PMID: 29673679 DOI: 10.1016/j.tjog.2018.02.023
    OBJECTIVE: To evaluate the outcome of transvaginal mesh surgery as a management of recurrent pelvic organ prolapse, in patients previously treated with sacrocolpopexy.

    CASE REPORT: A series of three patients who developed recurrent pelvic organ prolapse more than 9 years after sacrocolpopexy. A 50-year-old and two 77-year-old patients who presented with recurrent pelvic organ prolapse at 9, 15 and 17 years, respectively after the primary abdominal sacrocolpopexy were managed by transvaginal mesh surgery.

    CONCLUSION: Management of recurrent pelvic organ prolapse using transvaginal mesh would be an option for patients treated previously by sacrocolpopexy.

  8. Fulltext A complicated urethrovaginal fistula following an inappropriate urethral diverticulum management
    Lo TS, Jaili SB, Ibrahim R
    Taiwan J Obstet Gynecol, 2017 Aug;56(4):534-537.
    PMID: 28805613 DOI: 10.1016/j.tjog.2016.10.004
    OBJECTIVE: Urethral diverticulum is uncommon, therefore appropriate evaluation, preoperative planning and counseling must be done in order to make correct diagnosis and prevent complications.

    MATERIALS AND METHODS: A case of anterior vaginal wall mass was treated elsewhere by a gynecologist as periurethral cyst abscess; incision and drainage were done but a symptom of pus discharge was observed after 2 weeks. Therefore, exploration, cyst wall excision and primary closure were done though histopathological examination surprisingly confirmed the presence of urethral tissue suggestive of diverticulum.

    RESULTS: Subsequently, she developed persistent urinary leakage along with urethrovaginal fistula for which they again performed pervaginal multilayer closure. Patient was later referred to us with recurrent urethrovaginal fistula. We performed posterior urethral fistulectomy with anterior vaginal wall flap and multilayer closure. Three years follow up reveals complete recovery.

    CONCLUSION: Even urethral diverticulum is a rare condition, should be kept in mind as early diagnosis and management.

    Taiwan J Obstet Gynecol, 2018 Feb;57(1):150-152.
    PMID: 29458888 DOI: 10.1016/j.tjog.2017.12.026
    OBJECTIVE: To know the diagnostic tools and proper management of ureterovaginal fistula following neglected vaginal foreign body in order to achieve optimal outcome.

    CASE REPORT: A case of ureterovaginal fistula associated with a neglected vaginal foreign body. The patient was complaining of a foul-smelling vaginal discharge and lower abdominal pain. On vaginal examination, a hard and large foreign body was found. Examination under anesthesia was performed, and an aerosol cap was removed from her vagina. The patient developed urinary incontinence after removal of the foreign body. Subsequent work-up demonstrated the presence of a right ureterovaginal fistula. The patient underwent an abdominal ureteroneocystostomy. At one year follow up, the patient had fully recovered.

    CONCLUSION: Ureterovaginal fistula following neglected vaginal foreign body is a serious condition. Early diagnosis, treatment of infection and proper surgical management can improve the outcome and decrease complications.

    Momtaz YA, Hamid TA, Ibrahim R
    Soc Sci Med, 2012 Sep;75(5):859-63.
    PMID: 22632847 DOI: 10.1016/j.socscimed.2012.03.047
    Unmet need as a significant factor affecting quality of life in later life has recently received considerable attention in gerontological research. The main aim of this study was to identify the prevalence, predicting factors, and negative consequence of unmet need among older Malaysians. The findings may be useful to reduce unmet need and the burden of its adverse consequence. The sample for this study consists of 400 functionally disabled elderly people aged 60 and over was obtained from a large national survey. Unmet need was operationally defined based on Manton's (1989) criteria. The findings from the present study showed about 18.0% of functionally disabled older Malaysians suffer from unmet need. Logistic regression revealed that gender (being male) and chronic health conditions are statistically associated with increased odds of unmet need after adjusting for other possible risk factors. Further results indicated that unmet need statistically increases odds of fall as a negative consequence of unmet need. The high prevalence rates of unmet need among disabled elderly men and chronically ill older persons suggest that policy makers should pay more attention to this vulnerable group to achieve good quality of life. The implications and limitations of the present study are discussed.

    Devan PAM, Hussin FA, Ibrahim R, Bingi K, Khanday FA
    Sensors (Basel), 2021 Jul 21;21(15).
    PMID: 34372210 DOI: 10.3390/s21154951
    Industrialization has led to a huge demand for a network control system to monitor and control multi-loop processes with high effectiveness. Due to these advancements, new industrial wireless sensor network (IWSN) standards such as ZigBee, WirelessHART, ISA 100.11a wireless, and Wireless network for Industrial Automation-Process Automation (WIA-PA) have begun to emerge based on their wired conventional structure with additional developments. This advancement improved flexibility, scalability, needed fewer cables, reduced the network installation and commissioning time, increased productivity, and reduced maintenance costs compared to wired networks. On the other hand, using IWSNs for process control comes with the critical challenge of handling stochastic network delays, packet drop, and external noises which are capable of degrading the controller performance. Thus, this paper presents a detailed study focusing only on the adoption of WirelessHART in simulations and real-time applications for industrial process monitoring and control with its crucial challenges and design requirements.

    PMID: 36679816 DOI: 10.3390/s23021020
    The gas sweetening process removes hydrogen sulfide (H2S) in an acid gas removal unit (AGRU) to meet the gas sales' specification, known as sweet gas. Monitoring the concentration of H2S in sweet gas is crucial to avoid operational and environmental issues. This study shows the capability of artificial neural networks (ANN) to predict the concentration of H2S in sweet gas. The concentration of N-methyldiethanolamine (MDEA) and Piperazine (PZ), temperature and pressure as inputs, and the concentration of H2S in sweet gas as outputs have been used to create the ANN network. Two distinct backpropagation techniques with various transfer functions and numbers of neurons were used to train the ANN models. Multiple linear regression (MLR) was used to compare the outcomes of the ANN models. The models' performance was assessed using the mean absolute error (MAE), root mean square error (RMSE), and coefficient of determination (R2). The findings demonstrate that ANN trained by the Levenberg-Marquardt technique, equipped with a logistic sigmoid (logsig) transfer function with three neurons achieved the highest R2 (0.966) and the lowest MAE (0.066) and RMSE (0.122) values. The findings suggested that ANN can be a reliable and accurate prediction method in predicting the concentration of H2S in sweet gas.
  14. Fulltext A Novel Hybrid Harris Hawk-Arithmetic Optimization Algorithm for Industrial Wireless Mesh Networks
    Devan PAM, Ibrahim R, Omar M, Bingi K, Abdulrab H
    Sensors (Basel), 2023 Jul 07;23(13).
    PMID: 37448072 DOI: 10.3390/s23136224
    A novel hybrid Harris Hawk-Arithmetic Optimization Algorithm (HHAOA) for optimizing the Industrial Wireless Mesh Networks (WMNs) and real-time pressure process control was proposed in this research article. The proposed algorithm uses inspiration from Harris Hawk Optimization and the Arithmetic Optimization Algorithm to improve position relocation problems, premature convergence, and the poor accuracy the existing techniques face. The HHAOA algorithm was evaluated on various benchmark functions and compared with other optimization algorithms, namely Arithmetic Optimization Algorithm, Moth Flame Optimization, Sine Cosine Algorithm, Grey Wolf Optimization, and Harris Hawk Optimization. The proposed algorithm was also applied to a real-world industrial wireless mesh network simulation and experimentation on the real-time pressure process control system. All the results demonstrate that the HHAOA algorithm outperforms different algorithms regarding mean, standard deviation, convergence speed, accuracy, and robustness and improves client router connectivity and network congestion with a 31.7% reduction in Wireless Mesh Network routers. In the real-time pressure process, the HHAOA optimized Fractional-order Predictive PI (FOPPI) Controller produced a robust and smoother control signal leading to minimal peak overshoot and an average of a 53.244% faster settling. Based on the results, the algorithm enhanced the efficiency and reliability of industrial wireless networks and real-time pressure process control systems, which are critical for industrial automation and control applications.
  15. Fulltext A novel fractional-order dead-time compensating controller for the wireless networks
    Devan PAM, Ibrahim R, Omar M, Bingi K, Nagarajapandian M, Abdulrab H
    Sci Rep, 2023 Oct 17;13(1):17658.
    PMID: 37848485 DOI: 10.1038/s41598-023-44515-7
    Wireless technology is becoming increasingly critical in industrial environments in recent years, and the popular wireless standards are WirelessHART, ZigBee, WLAN and ISA100.11a, commonly used in closed-loop systems. However, wireless networks in closed-loop control experience packet loss or drops, system delay and data threats, leading to process instability and catastrophic system failure. To prevent such issues, it is necessary to implement dead-time compensation control. Traditional techniques like model predictive and predictive PI controllers are frequently employed. However, these methods' performance is sluggish in wireless networks, with processes having long dead times and set-point variations, potentially affecting network and process performance. Therefore, this paper proposes a fractional calculus-based predictive PI compensator for wired and wireless networks in the process control industries. The proposed technique has been simulated and evaluated on industrial process models, including pressure, flow, and temperature, where measurement and control are carried out wirelessly. The wireless network's performance has been evaluated based on packet loss, reduced throughput, and increased system latency. The proposed compensator outperformed traditional methods, demonstrating superior set-point tracking, disturbance rejection, and delay compensation characteristics in the performance evaluations of the first, second, and third-order systems. Overall, the findings indicate that the proposed compensator enhances wireless networks' performance in the process control industry and improves system stability and reliability by reducing almost half of the overshoot and settling an average of 8.3927% faster than the conventional techniques in most of the systems.

    Sci Rep, 2024 Feb 26;14(1):4657.
    PMID: 38409430 DOI: 10.1038/s41598-024-54444-8
    The evolution of Internet technology has led to an increase in online users. This study focuses on the pivotal role of visual elements in web content conveyance and their impact on user browsing behavior. Therefore, the use of visual elements in web design based on big data has aroused widespread concern among web designers, they apply visual elements to their web design works to make the web more attractive. This study examines the composition and distribution characteristics of key visual elements identified through user behavior data in a big data environment and discusses the use of visual elements in web design in the era of network economy. In addition, this paper issued 200 questionnaires to investigate the degree of attention to visual elements in web pages for users of different occupations and different educational backgrounds. Our survey indicated that visual elements captured the attention of 41% of corporate employees, whereas a mere 1% of social welfare workers focused on web content; 36% of undergraduates pay attention to visual elements of web pages, but only 5% and 4% of postgraduates and doctoral degrees and above. Therefore, the visual elements of the designed web page need to conform to the user's cultural background and professional background.

    PMID: 34675717 DOI: 10.2147/RMHP.S325184
    Objective: The aim of this study was to validate the Arabic version of General Medication Adherence Scale (GMAS) in Sudanese patients with type 2 diabetes mellitus (T2DM).

    Methods: A 3-month cross-sectional study was conducted among patients with T2DM at Al-Daraja Health Center, located in Wad Medani, Sudan. A convenient sample of patients was selected, and the study sample size was calculated using the item response ratio. Factorial, known group, and construct validities were determined. Internal consistency and reliability were also determined.

    Results: Responses were provided by 500 patients. The average medication adherence score was 30 (median 31). The normed fit index (NFI) was 0.950, the comparative fit index (CFI) was 0.963, the incremental fit index (IFI) was 0.963, and the root-mean-square error of approximation (RMSEA) was 0.071. The results from these fit indices indicated a good model. Factorial, known group and construct validities were all established. A significant association was found between adherence score and age (P = 0.03) since a larger proportion of older patients were found to have high adherence compared to patients in other age groups. The reliability (α) of the questionnaire was 0.834.

    Conclusion: The Arabic version of GMAS was validated in Sudanese patients with T2DM making it a suitable scale to be used in this population.

    Psychogeriatrics, 2013 Sep;13(3):182-8.
    PMID: 25913768 DOI: 10.1111/psyg.12009
    Elder abuse is a pervasive phenomenon around the world with devastating effects on the victims. Although it is not a new phenomenon, interest in examining elder abuse is relatively new. This paper aims to provide an overview of the aetiological theories and measures of elder abuse. The paper briefly reviews theories to explain causes of elder abuse and then discusses the most commonly used measures of elder abuse. Based on the reviewed theories, it can be concluded that elder abuse is a multifactorial problem that may affect elderly people from different backgrounds and involve a wide variety of potential perpetrators, including caregivers, adult children, and partners. The review of existing measurement instruments notes that many different screening and assessment instruments have been developed to identify elders who are at risk for or are victims of abuse. However, there is a real need for more measurements of elder abuse, as the current instruments are limited in scope.
