Role of age and sex in the incidence of adverse effects among diabetic patients treated with glipizide.

Glipizide is an antidiabetic drug that belongs to a class of medication known as sulfonylureas. It is considered one of the highly prescribed antidiabetic drugs for the treatment of type II diabetes in patients following a kidney transplant. It lowers blood glucose levels by causing the release of insulin from ß-cells in the pancreas. Its main metabolizing pathway is through the liver. It has several adverse effects, which range from an upset stomach to glipizide-induced haemolytic anaemia and hypoglycaemia. These adverse effects may be spontaneous, or they could have a genetic cause. The present study aimed to assess and document the incidence of glipizide-induced adverse reactions among patients prescribed the drug. The present retrospective case-control study used the electronic medical records of patients prescribed glipizide for the past 3 years. These records were reviewed to extract and document cases and/or signs of glipizide-induced adverse reactions. The results revealed that the incidence of adverse effects was higher among female patients (odds ratio, 2.40, P<0.001). Moreover, the results revealed that the likelihood of developing adverse drug reactions among patients <40 years of age was higher than in older patients (P>0.05). The outcomes of the present study are expected to prompt future studies to take sex and age into consideration, in an aim to improve treatment outcomes, reduce adverse events and decrease the burden of unnecessary costs for healthcare systems. Recommendations also include genetic screening prior to administering the medication, educating the patients and caregivers on the possibility of adverse drug reactions, and routine follow-up. This issue is of utmost importance to achieve the optimal outcomes with the minimal detrimental effects.

Laboratory features and pharmacological management of early and late-onset primary Sjögren's syndrome.

BACKGROUND: Primary Sjögren's Syndrome (pSS) is a systemic chronic autoimmune disorder that contributes to dry mouth (xerostomia) and eyes (xerophthalmia). It mainly affects females between 40 and 60 years old. So far, there is no treatment to cure SS; however, there is a list of medications that can ameliorate the symptoms. In addition, there has been no single test until now to detect pSS, but clinical and immunological investigations are applied as diagnostic tools. Therefore, this study aimed to explore the characteristics of pSS in Saudi patients based on the onset of the disease through laboratory findings and pharmaceutical management. METHODOLOGY: This retrospective study examined diagnosed patients with pSS between 2018 and 2023 from the National Guard Hospital, Saudi Arabia. Data of pSS patients was categorized into two groups: early (under 40 years old) and late-onset (40 years old and above). Data on demographic information, mortality rate, and blood tests such as complete blood count (CBC), creatinine, erythrocyte sedimentation rate (ESR), and vitamin levels, in addition to prescribed medications, were collected from the patient's medical record. Chi-square and t-tests were mainly used, and statistical significance was determined at a P-value less than 0.05. RESULTS: A total of 453 patients were included in the study, where the early-onset group comprised 136 and the late-onset group comprised 317 patients. The mean age of the early and late onset was 34.2 and 60.4, respectively. ESR was significantly higher in the early (46.3 mm/hr) and late-onset (49.8 mm/hr). The most common medication used by all pSS patients was hydroxychloroquine. However, artificial tears were mainly observed in the late-onset group. Other medications, such as pilocarpine, methotrexate, and azathioprine, were prescribed to pSS patients to a lesser extent. CONCLUSION: This study suggests that the onset of pSS could occur even before the age of 40 among Saudi citizens. Notably, elevated ESR levels appeared to be a feature of pSS, which was consistent with other previous findings. The variability of some medications between early-onset and late-onset pSS may indicate disease progression. However, further investigations are required to confirm this observation.

Enhancing Patient Safety: A Cross-Sectional Study to Assess Medical Interns' Attitude and Knowledge About Medication Safety in Saudi Arabia.

Introduction and aim Medication errors (MEs) pose a severe threat in the medical field. Since such errors are preventable, it is paramount for all healthcare workers to be educated on the matter. This study aimed to assess medical interns' attitudes and knowledge of medication safety and errors. We also aimed to validate current university programs to educate students about medication safety and errors. Methods A cross-sectional study that utilized a self-administered online questionnaire comprised 31 questions. The questionnaire was distributed via social media networks, such as WhatsApp, Twitter, email, Instagram, and Snapchat among 100 medical, pharmacy, and nursing interns in Saudi Arabia. The study population included both Saudi and non-Saudi interns. Results The majority of participants, comprising 92% (n=92), indicated that they were familiar with the definition of medication errors (ME). Additionally, 85% (n=85) expressed their willingness to report instances of MEs when medications were not prescribed but required. Moreover, 90% (n=90) of the surveyed individuals expressed their willingness to report MEs in situations where patients did not receive medications as prescribed. In cases where patients experienced harm and required treatment due to an ME, 91% (n=91) of respondents committed to reporting such incidents. A total of 52 (52%) respondents stated that they would report MEs regardless of whether they reached/harmed the patient. A good ME knowledge level was observed in 48% of respondents. A higher likelihood of good ME knowledge was significantly associated with safety reporting system (SRS) awareness and reporting MEs regardless of whether they reached/harmed the patient (p<0.05). College, awareness/attitude, or other demographic factors were not significantly related to ME knowledge (p>0.05). Conclusion This study showed that although interns in the healthcare field do have some knowledge about MEs, there is still a significant need to improve their knowledge. This can be achieved through various ways, one of which is by implementing this topic into the university curricula.

A highlight on carbamazepine-induced adverse drug reactions in Saudi Arabia: a retrospective medical records-based study.

The link between human leukocyte antigen (HLA) alleles and carbamazepine-induced cutaneous, respiratory, and gastrointestinal adverse drug reactions (ADR) has created a window of opportunity for preventing certain forms of cutaneous adverse drug reactions (cADRs); however, there is not enough data to make pharmacogenomic recommendations that can be implemented globally. The aim of this study is to assess and document carbamazepine-induced adverse reactions among prescribed Saudi/non-Saudi patients. A retrospective chart review was performed for patients who received carbamazepine (CBZ) in the period between 2016 and 2020, in the Kingdom of Saudi Arabia. Data were gathered and descriptive statistical analyses were performed on the data for the study sample. Comparisons were made using the chi-square test or independent samples' t-test. Statistical significance was considered at p < .05. All statistical analyses were performed using IBM SPSS 21.0 (Armonk, NY; IBM Corp). Results from multivariate logistic regression analyses showed that higher likelihood of carbamazepine-induced adverse reactions was significantly associated with younger age, OR = 0.82, 95% CI (0.74, 0.90); p < 0.001. Patients who were prescribed CBZ for reasons other than epilepsy or seizures were significantly more likely to develop carbamazepine-induced adverse reactions (epilepsy vs. other; OR = 0.63, p = 0.013; seizures vs. other; OR = 0.59, p = 0.018). Gender or medication duration were not related to carbamazepine-induced adverse reactions (p > 0.05). The findings of this study are comparable with those of other studies assessing carbamazepine-associated adverse reactions in children and adults. Recommendations include genetic prescreening, educating patients and parents on the possibility of adverse reactions, and routine laboratory monitoring.

Awareness and attitudes of oncology specialists toward dihydropyrimidine dehydrogenase testing in Saudi Arabia.

BACKGROUND: Fluoropyrimidines (FP) are among the most common class of prescribed anti-neoplastic drugs. This class has severe to moderate toxicity in around 10%-40% of those who take 5-fluorouracil (5-FU) or capecitabine for the treatment of cancer. In practice many patients with severe toxicities from FP use had dihydropyrimidine dehydrogenase (DPD) enzyme deficiency. Several studies have proposed DPD screening before treatment with 5-fluorouracil (5-FU) and capecitabine or other drugs belonging to the FP group. This study aims to assess the level of awareness and attitudes of oncology specialists in Saudi Arabia toward genetic screening for DPD prior to giving FP. This highlights the importance of health guidelines required for implementation in our health care system, as a framework to adopt testing as a regular practice in clinical care. Based on the findings in this study, guidelines have been suggested for the Middle East North Africa region. METHODS: A cross-sectional survey study was conducted during 2021 targeting oncologists and clinical pharmacists working in the oncology departments across Saudi Arabia. RESULTS: A total of 130 oncologists and pharmacists completed the questionnaire representing a response rate of 87%. Most of the respondents indicated that they prescribe FP in clinical practice, but 41% of respondents reported that they have never ordered a specific molecular test during their practice. Only 20% of respondents reported that they often screen for DPD deficiency prior to prescribing FP. Significantly higher rates of awareness of potential dihydropyrimidine dehydrogenase gene (DPYD) mutation were observed among respondents in governmental hospitals (81.1% vs. 47.4% in private hospitals), and among those with more years of practice (80.6% if 5 or more years of practice vs. 59.3% if less than 5 years of practice). Also, higher rates of observing the impact of DPD testing were present among respondents with a PharmD (35% vs. 11% for oncologists and 18% for other professions) and among those with 5 or more years of practice (24.6% vs. 7.7% among those with less than 5 years). CONCLUSION: While in some institutions there is a high level of awareness among oncology specialists in Saudi Arabia regarding the effect of the potentially serious DPD enzyme deficiency as a result of gene mutations, screening for these mutations prior to prescribing FP is not a routine practice in hospitals across the country. The findings of this study should promote personalized medicine with recognition of interpatient variability via DPD testing to manage the risks of FP prescribing more effectively in the Kingdom of Saudi Arabia.

Failure to demonstrate effects of interruptions on diagnostic reasoning: three experiments.

BACKGROUND: Diagnostic error is a major source of patient suffering. Researchshows that physicians experience frequent interruptions while being engaged with patients and indicate that diagnostic accuracy may be impaired as a result. Since most studies in the field are observational, there is as yet no evidence suggesting a direct causal link between being interrupted and diagnostic error. Theexperiments reported in this article were intended to assess this hypothesis. METHODS: Three experiments were conducted to test the hypothesis that interruptions hurt diagnostic reasoning and increase time on task. In the first experiment (N = 42), internal medicine residents, while diagnosing vignettes of actual clinical cases were interrupted halfway with a task unrelated to medicine, solving word-spotting puzzles and anagrams. In the second experiment (N = 78), the interruptions were medically relevant ones. In the third experiment (N = 30), we put additional time pressure on the participants. In all these experiments, a control group diagnosed the cases without interruption. Dependent variables were diagnostic accuracy and amount of time spent on the vignettes. RESULTS: In none of the experiments interruptions were demonstrated to influence diagnostic accuracy. In Experiment 1: Mean of interrupted group was 0.88 (SD = 0.37) versus non- interrupted group 0.91 (SD = 0.32). In Experiment 2: Mean of interrupted group was 0.95 (SD = 0.32) versus non-interrupted group 0.94 (SD = 0.38). In Experiment 3: Mean of interrupted group was 0.42 (SD = 0.12) versus non-interrupted group 0.37 (SD = 0.08). Although interrupted residents in all experiments needed more time to complete the diagnostic task, only in Experiment 2, this effect was statistically significant. CONCLUSIONS: These three experiments, taken together, failed to demonstrate negative effects of interruptions on diagnostic reasoning. Perhaps physicians who are interrupted may still have sufficient cognitive resources available to recover from it most of the time.

The current practice of using angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers in diabetic hypertensive and non-hypertensive patients. Is there a room for vitamin D?

OBJECTIVES: To determine the current pattern of using angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs) in diabetic nephropathy (DN), and assess physician awareness of using vitamin D in the prevention and treatment of DN. METHODS: A cross-sectional study implementing a validated questionnaire, which was distributed to physicians in the aforementioned specialties in 3 hospitals in Saudi Arabia (Almanee Hospital, King Saud Medical City [KSMC], and Riyadh Care Hospital [RCH]) between April 2019 and November 2019. We used IBM SPSS 26.0 to perform descriptive statistical analyses and comparisons were based on the Chi-square test. RESULTS: Forty-one physicians (30%) reported the use of combination therapy of ACEi and ARBs. Fifty-six (41%) physicians reported that they never used vitamin D in the treatment of DN, and 48% agreed that vitamin D can benefit patients with DN. 52% of the respondents reported the existence of guidelines. The vast majority (94%) recommended clearer guidelines on monitoring renal function in patients treated with ACEi or ARBs. CONCLUSION: There is a universal agreement among physicians regarding the use of ACEi and ARBs for the treatment of DN with limited awareness of the bene ts of using vitamin D. Hence, the development of specific guidelines for its use are recommended.

Current umbilical cord clamping practices and attitudes of obstetricians and midwives toward delayed cord clamping in Saudi Arabia.

BACKGROUND: In Saudi Arabia, as in many countries, there is usually no clear definition of the timing of umbilical cord clamping (UCC) in the policies and procedures used by hospitals. The World Health Organization (WHO) recommends delayed cord clamping (DCC) ( > 1 minute after birth) as it can significantly improve hemodynamics and long-term neurodevelopment. OBJECTIVE: To investigate current practices of healthcare professionals on the timing of UCC in Saudi Arabia. DESIGN: Cross-sectional survey. SETTING: Five tertiary hospitals in Riyadh, Saudi Arabia, during May to October 2016. SUBJECTS AND METHODS: Obstetricians and midwives completed a widely-used questionnaire on UCC practices. MAIN OUTCOME MEASURE(S): Current UCC practices and attitudes of obstetricians and midwives toward DCC. RESULTS: Eighty-two obstetricians and 75 midwives completed the questionnaire for a response rate of 80%. The majority of respondents were aged 30 years or older (81%) and 84% were females. Most respondents were non-Saudi (66%) and had an educational level of bachelor's degree or higher (72%). Only 42% of respondents reported the existence of UCC guidelines in their practice; 38% reported the existence of a set time for UCC when the neonate was term and healthy, and only 32% had a set time for UCC in preterm neonates. While lower levels of agreement were reported among obstetricians and midwives on the benefits of DCC for babies requiring positive pressure ventilation, the majority of respondents (69-71%) thought that DCC was generally good for both term and preterm babies and that its benefits extend beyond the neonatal period. CONCLUSIONS: While the majority of obstetricians and midwives that participated in this study had a positive perception toward DCC, this did not translate to their daily practice as most of these professionals reported a lack of existing UCC guidelines in their institutions. Further studies are warranted to confirm these findings. LIMITATIONS: Participant selection by convenience sampling.
