RESUMEN
Background: Coronavirus disease (COVID-19) vaccines play an essential role in boosting immunity, preventing severe diseases, and alleviating the Covid-19 health crisis. Objective: This study aimed to explore the type and severity of short-term adverse reactions associated with BNT162 (Pfizer-BioNTech), mRNA 1273 (Moderna), and viral vector vaccines and to compare the incidence of post-vaccination Covid-19 infection among the Birzeit University community in Palestine. Methods: This questionnaire-based retrospective cross-sectional study was conducted among individuals who were vaccinated with at least one dose of any COVID-19 vaccine offered in Palestine during the COVID-19 pandemic. The study included participants aged 18 years and older who were vaccinated with Pfizer, Moderna, Sputnik Light, or Sputnik v. Results: A total of 558 participants who were administered COVID-19 vaccine were included in the study. Sputnik (239), Pfizer vaccine recipients (236), and Moderna vaccine recipients (83). Of the viral vector vaccine recipients, 57 (23.8%) had a post-vaccination infection, compared to 30 (12.7%) for Pfizer and seven (8.4%) for Moderna. Furthermore, the reported adverse effects in the viral victor group were higher than those in the Moderna and Pfizer groups (71.7, 66.3, and 61.9%, respectively). Chills, headache, fatigue, abdominal pain, and joint pain were significantly higher in the Viral Vector vaccine group than the Moderna and Pfizer vaccine. Vomiting, tiredness, and fatigue were significantly less likely to be complained of by Pfizer vaccine recipients compared to Moderna and Viral Vector vaccine recipients (p < 0.05). Conclusions: Breakthrough infections were associated with both viral vectors and mRNA; however, the mRNA vaccine had less reported post-vaccine infection. Furthermore, the Pfizer/BioNTech COVID-19 vaccine group reported fewer commonly reported side effects (fever, chills, headache, fatigue, muscle pain, joint pain, nausea, and dizziness), followed by the Moderna and viral vector vaccines. Females and underweight participants experienced more adverse effects with both vaccines, and fewer common side effects were reported by all participants.
RESUMEN
Background: Isotretinoin is a commonly prescribed medication for the treatment of acne. It is associated with serious side effects that require monitoring and adherence by patients and healthcare providers. No studies have been conducted in Palestine to explore isotretinoin prescribing and utilization. Objective: This study aims to evaluate the current clinical practices, adherence to clinical guidelines, efficacy, and reported side effects associated with Isotretinoin treatment in Palestine. Methods: A descriptive cross-sectional online questionnaire-based study using social media platforms (eg, Facebook and Telegram) was conducted among Birzeit University students in April 2023. This study included participants aged ≥ 18 years with a history of isotretinoin treatment; subjects with incomplete data were excluded. Statistical significance was set at P < 0.05. SPSS version 27 was used for data analysis. Results: A total of 548 participants were included in the study, the majority of most of whom were female (96%). The most predominant side effects were cracked, dry lips and xeroderma (96.2%). Moreover, 12% of participants had depression. Most respondents were educated about medication side effects and only 39.1% were counseled about blood donation. Of the 59 sexually active women, only 4 (6.8%) were asked for a recent pregnancy test. A total of 60.2% of dermatologists adhered to the American Academy of Dermatology (AAD) guidelines, and 48.7% ordered the required laboratory tests before initiating isotretinoin treatment. Only 1.7% of pharmacists followed the FDA-suggested protocols for dispensing isotretinoin to childbearing females. Conclusion: Adherence to isotretinoin safety prescribing protocols to provide patient education, monitoring, and ordering of laboratories to ensure patient safety can be improved by adapting policies and protocols in pharmacy and medical practice in Palestine to monitor and enforce adherence when prescribing, dispensing, or taking high-risk medications.
RESUMEN
Blue-green algae, or cyanobacteria, may be prevalent in our rivers and tap water. These minuscule bacteria can grow swiftly and form blooms in warm, nutrient-rich water. Toxins produced by cyanobacteria can pollute rivers and streams and harm the liver and nervous system in humans. This review highlights the properties of 25 toxin types produced by 12 different cyanobacteria genera. The review also covered strategies for reducing and controlling cyanobacteria issues. These include using physical or chemical treatments, cutting back on fertilizer input, algal lawn scrubbers, and antagonistic microorganisms for biocontrol. Micro-, nano- and ultrafiltration techniques could be used for the removal of internal and extracellular cyanotoxins, in addition to powdered or granular activated carbon, ozonation, sedimentation, ultraviolet radiation, potassium permanganate, free chlorine, and pre-treatment oxidation techniques. The efficiency of treatment techniques for removing intracellular and extracellular cyanotoxins is also demonstrated. These approaches aim to lessen the risks of cyanobacterial blooms and associated toxins. Effective management of cyanobacteria in water systems depends on early detection and quick action. Cyanobacteria cells and their toxins can be detected using microscopy, molecular methods, chromatography, and spectroscopy. Understanding the causes of blooms and the many ways for their detection and elimination will help the management of this crucial environmental issue.

Background: Proton pump inhibitors (PPIs) are commonly prescribed medications that are thought to increase the risk of cardiovascular events because they reduce the effectiveness of clopidogrel via shared hepatic pathways. Objective: This study examined the prevalence of concomitant prescribing of clopidogrel/PPI among patients diagnosed with acute coronary syndrome and the adverse cardiovascular event associated with this interaction. Methods: A retrospective cohort study was conducted by retrieving patient data from the Nat Health Insurance claims processor database in Palestine. Adults diagnosed with Acute Coronary Syndrome (ACS) from 2019 through 2021 who were prescribed clopidogrel or clopidogrel in combination with a PPI were included in the study. Endpoints were adverse cardiac events, including readmission for revascularization during the first year of treatment. Results: The study included 443 patients; the prevalence of prescribing concomitant clopidogrel with a PPI was 74.7%, whereas 49.2% were prescribed interacting PPI (omeprazole, esomeprazole, and lansoprazole). 59 (13.3%) of participants experienced a cardiovascular event within 1 year of starting therapy, including 27 (12.4%) patients who had a cardiovascular event while taking an interacting PPI. No significant association was found between PPI administration and increased CV event risk in patients receiving concomitant clopidogrel and PPIs therapy (p = 0.579). Conclusion: In this study, we observed a high prevalence of prescribing a PPI in combination with clopidogrel, regardless of the FDA recommendations. No significant increase in cardiovascular events was observed in patients receiving concomitant clopidogrel and PPI therapy.
RESUMEN
Background: Proton pump inhibitors (PPIs) are the most effective agents for managing acid-related disorders. However, inappropriate prescribing of PPIs is becoming an issue of concern. Objective: This study aimed to assess the appropriate utilization of PPIs in terms of indication, dose, frequency, and route of administration during admission and discharge. Furthermore, direct costs associated with inappropriate PPI use were calculated. Methods: A descriptive cross-sectional study was conducted at the internal medicine department of a tertiary hospital in Palestine from January 1, 2021, to June 30, 2021. The medical records of patients aged 18 years or older, hospitalized for 48 hours or more, and receiving oral or intravenous (IV) PPIs during their stay were collected and evaluated for the appropriateness of PPIs prescribed according to clinical guidelines. Results: Of 262 patients, 80.2% had an appropriate indication for prophylaxis (67.6%) or treatment (12.6%). A total of 230 patients were prescribed IV pantoprazole.182 (79.1%) had an appropriate indication, whereas 122/182 (67%) received IV PPI instead of oral without an appropriate indication. Of the 32 patients who received 20 mg of oral omeprazole, 28 (87.5%) had an appropriate indication, dose, and route of administration, whereas 16/28 (57.1%) had an inappropriate frequency. At discharge, 32.5% of patients were discharged with unnecessary PPI prescriptions. The total direct cost of inappropriate PPI Indications and route of administration in 188 patients over six months was $1518. Conclusion: This study showed that most patients received a PPI for an appropriate indication with the correct dose. However, a high prevalence of inappropriate IV pantoprazole administration was observed, resulting in the highest costs, demonstrating the importance of correctly ordering IV medications. Adherence to clinical guidelines, such as those of the American College of Gastroenterology (ACG), will improve the appropriateness of PPI prescribing, prevent complications, and reduce healthcare costs.
RESUMEN
BACKGROUND: The Pfizer BioNTech COVID-19 vaccine was the first to receive emergency authorization and approval from the FDA. Therefore, it is preferred by most recipients; however, many people are concerned about the vaccine's side effects. At the time of the study, December 2021, Palestine lacked a national reporting system for monitoring adverse vaccine effects. Therefore, this study investigates the post-vaccine adverse events following the Pfizer/BioNTech COVID-19 Vaccine administration in Palestine and identifies the occurrence, extent, and severity among university staff, employees, and students at Birzeit University. METHOD: A questionnaire-based retrospective cross-sectional study was conducted using a university website (Ritaj), social media platforms (e.g., Facebook and Telegram), and in-person interviews. The Chi-square, Fisher's exact, and McNemar's tests were used to investigate significant relationships. Data were analyzed using SPSS version 22. RESULTS: In total, 1137 participants completed the questionnaire, 33.2% were males, and the mean age was 21.163 years. All participants received at least one dose of the Pfizer-BioNTech COVID-19 vaccine. Approximately one-third of participants reported no adverse effects after receiving the first, second, or third doses (34%, 33.6%, and 32.5%, respectively). The most commonly reported adverse events were fever, chills, headache, fatigue, pain and swelling at the injection site, muscle pain, and joint pain. Allergic reactions were reported by 12.7% of the participants; furthermore, participants with a history of allergy or anaphylaxis before vaccination had a significantly higher tendency for post-vaccination allergic reactions. Eight participants reported rare side effects, including 7 (0.6%) cases of thrombocytopenia and one (0.1%) case of myocarditis. Males aged less than 20 years and smokers were significantly less likely to complain of adverse events. The number of reported side effects was significantly higher after the second vaccine dose than after the first dose. Finally, participants infected with COVID-19 before vaccination was significantly associated with side effects such as fever, chills, shortness of breath, and persistent cough. CONCLUSION: In this study, the most common post- BNT162b2 Vaccination reported self-limiting side effects similar to those reported by Pfizer/BioNTech Company. However, higher rates of allergic reactions were reported in this sample. Rare side effects, such as thrombocytopenia and myocarditis, were reported by 8 participants. COVID vaccines have been developed at an accelerated pace, and vaccine safety is a top priority; therefore, standard monitoring through a national adverse event reporting system is necessary for safety assurance. Continuous monitoring and long-term studies are required to ensure vaccine safety.

Objective: To measure the prevalence and identify risk factors associated with drug-drug interactions among patients admitted to internal medicine departments in Palestinian hospitals. Methods: A retrospective cross-sectional observational study was conducted. Data were obtained from patient files from the internal medicine departments in Palestinian hospitals from 1 September 2017, to 31 March 2018. The data collected included patient gender, age, length of hospitalization, medications prescribed, and the number of medications. The digital clinical decision support system IBM Micromedex® was used to assess potential drug-drug interactions. Results: The number of patients included in this study is 513. The total number of potential drug-drug interactions detected in study participants is 1558. The average number of potential drug-drug interactions per patient was found to be 3 ± 3.9. Among study participants, 66.1% (n = 339) were found to have potential drug-drug interactions in their current medications. The most commonly encountered drug-drug interactions type was "major" drug-drug interaction, which was encountered in 43.6% (n = 681) of total detected drug-drug interactions. Other types of drug-drug interactions were encountered in 42% (n = 647), 14% (n = 224), and 0.4% (n = 6) which were moderate, minor, and contraindicated drug-drug interactions, respectively. Patients' age, number of medications, and length of hospitalization were associated with the increased risk of potential drug-drug interactions. Conclusion: The results indicated a high prevalence of potential drug-drug interactions in Palestinian hospitals, associated with polypharmacy, increased age, and increased length of hospitalization. Therefore, managing patient medication by a drug expert such as a clinical pharmacist to identify and resolve potential drug-drug interactions will possibly decrease the high prevalence of drug-drug interactions, prevent patient harm, and decrease the cost of hospitalization.
RESUMEN
Background: Elderly patients suffer from chronic diseases and are prone to polypharmacy and potentially inappropriate prescribing (PIP). This study aimed to identify potentially inappropriate medications (PIMs) and potential prescribing omissions (PPOs) among elderly patients in a tertiary care hospital setting and to estimate the prevalence of polypharmacy. Methods: This multicenter retrospective observational study reviewed patient data from two major Palestinian hospitals. The collected data included patient demographics, comorbidities, and medications administered during hospitalization and discharge. The study included 247 patients aged ≥ 65 years hospitalized between January 2019 and December 2019. The STOPP/START criteria version 2 was used to identify the prevalence of PIMs and PPOs. Clinical pharmacists verified the data, and SPSS was used for data analysis. Descriptive statistics, one-tailed bivariate correlations, and Pearson's test were applied to the variables of interest to examine their association with the STOPP/START criteria. Results: A total of 247 patients were included in the study, and 50.2% were females. As a result, 165 (66.8%) participants were identified with PIPs, including 30 patients with PPOs, 91 with PIMs, and 44 with both. Furthermore, the prevalence of PIP during hospitalization and discharge was 56.29% and 64.39%, respectively. Polypharmacy (5-9 medications) was 44.5% and 52.1% during hospitalization and discharge, respectively, and excessive polypharmacy (ten medications or more) was 33.6% and 16.4% during hospitalization and discharge, respectively. Moreover, 47.3% of the patients had a comorbidity index of ≥ 5. Conclusion: This study identified a high prevalence of PIPs among elderly patients during hospital admission and discharge. In addition, more than half of the geriatric patients in this study had PIP and a high prevalence of polypharmacy. Therefore, this study emphasizes the importance of adapting evidence-based tools, such as the STOPP/START criteria, to optimize patient medication therapy and guide prescribers in identifying and resolving PIMs and PPOs.

Introduction: Venous thromboembolism (VTE) is the most preventable complication in hospitalized patients. The main objective of this study was to evaluate the adherence of current clinical practice to the established guidelines at a Palestinian teaching hospital. Methods: This cross-sectional, retrospective, observational study was conducted at a Palestinian Teaching Hospital. The medical records of patients admitted to the medical floor over 18 years of age and hospitalized for longer than 24 hours between January 1 and May 31, 2019, were included. Patients taking anticoagulants with incomplete or duplicated medical records were excluded from the study. A data collection sheet was developed, and clotting and bleeding risks were assessed using the Padua and IMPROVE risk assessment models (scores). The data were analyzed using IBM SPSS (version 25). Results: In total, 408 patients were included in the study, 222 of whom received thromboprophylaxis (54.4%). Of the hospitalized patients, 112 (27.5%) had a high risk of developing VTE (Padua score ≥ 4), and 73 patients were eligible for VTE pharmacological prophylaxis; however, only 44 (60.3%) received the appropriate prophylaxis. In addition, 296 patients had low Padua scores, indicating that pharmacological prophylaxis was not indicated. However, 144 (48.6%) patients received prophylaxis. The mean Padua and IMPROVE risk scores were 2.25 ± 2.08 and 4.44 ± 2.72, respectively. Among the patients, 17.6% had a high risk of bleeding (IMPROVE score ≥ 7). Conclusion: VTE prophylaxis among hospitalized medically ill patients was mostly inappropriate; 80.18% of the patients received inappropriate prophylaxis, and only 60.3% of eligible patients received appropriate prophylaxis. Adapting assessment models or checklists in clinical practice based on clinical guidelines for VTE risk stratification is a practical and effective method to improve VTE prophylaxis management and select the appropriate therapy to prevent toxicity or complication.

Background: Diabetes mellitus (D.M.) is a chronic metabolic disease caused by decreased insulin secretion, which increases the risk of cardiovascular diseases. Evidence has shown that statins reduce cardiovascular risk in patients with diabetes; moreover, most clinical guidelines recommend statins. Objective: This study aimed to assess the level and status of adherence to guidelines on statin prescription in patients with diabetes mellitus in a primary care setting in Palestine. Methods: A retrospective cross-sectional descriptive study was conducted at an ambulatory center in Palestine. Data were collected by auditing prescription records and reviewing medical charts of patients with diabetes who visited the clinic from February 15 to March 17, 2021. The collected data included patient characteristics, comorbidities, lipid profiles, and statin prescription. A chi-square test was used to evaluate the appropriateness of the prescribed statins with different demographic and clinical variables. Statistical significance was set at p < 0.05. Statistical Package for Social Sciences (SPSS) version 22 was used to analyze the data. Results: Out Of 262 diabetic patients included in the analysis, 74% were prescribed appropriate statin therapy according to the American Diabetes Association (ADA) guidelines, and 24% of patients had inappropriate statin therapy or needed statins. Furthermore, 82.8% were on high-intensity statins, while 11% were not taking any statins. More than 60% of patients had uncontrolled diabetes and hypertension. Conclusion: Most guidelines recommend statin therapy in diabetic patients owing to its benefits in preventing cardiovascular complications. In this study, most patients were on appropriate STATIN therapy; however, 50% of diabetic patients had LDL of more than 100 mg/dl, and 25% were not prescribed statins, increasing their risk of ASCVD. Therefore, we recommend strict adherence to the established guidelines on statins prescribed to patients with diabetes to prevent cardiovascular complications, save lives, and reduce healthcare costs.
RESUMEN
Background: Diagnosis of co-infections with multiple pathogens among hospitalized coronavirus disease 2019 (COVID-19) patients can be jointly challenging and essential for appropriate treatment, shortening hospital stays and preventing antimicrobial resistance. This study proposes to investigate the burden of bacterial and fungal co-infections outcomes on COVID-19 patients. It is a single center cross-sectional study of hospitalized COVID-19 patients at Beit-Jala hospital in Palestine. Methods: The study included 321 hospitalized patients admitted to the ICU between June 2020 and March 2021 aged ≥20 years, with a confirmed diagnosis of COVID-19 via reverse transcriptase-polymerase chain reaction assay conducted on a nasopharyngeal swab. The patient's information was gathered using graded data forms from electronic medical reports. Results: The diagnosis of bacterial and fungal infection was proved through the patient's clinical presentation and positive blood or sputum culture results. All cases had received empirical antimicrobial therapy before the intensive care unit (ICU) admission, and different regimens during the ICU stay. The rate of bacterial co-infection was 51.1%, mainly from gram-negative isolates ( Enterobacter species and K.pneumoniae). The rate of fungal co-infection caused by A.fumigatus was 48.9%, and the mortality rate was 8.1%. However, it is unclear if it had been attributed to SARS-CoV-2 or coincidental. Conclusions: Bacterial and fungal co-infection is common among COVID-19 patients at the ICU in Palestine, but it is not obvious if these cases are attributed to SARS-CoV-2 or coincidental, because little data is available to compare it with the rates of secondary infection in local ICU departments before the pandemic. Comprehensively, those conclusions present data supporting a conservative antibiotic administration for severely unwell COVID-19 infected patients. Our examination regarding the impacts of employing antifungals to manage COVID-19 patients can work as a successful reference for future COVID-19 therapy.

Aim: COVID-19, the novel coronavirus, has been characterized as a pandemic, as it spreads all over the world and has so far infected more than 20 million worldwide. In Palestine, the first seven cases were documented on March 5 2020, followed by the declaration of the state of emergency. This study aimed to assess knowledge, attitudes and practices toward COVID-19 among Birzeit University students. Subject and methods: A cross-sectional study was carried out; a questionnaire was developed based on the WHO, CDC, and ECDC recommendations. The questionnaire was distributed online and filled out by Birzeit University students. Chi-square testing was performed to check for significant association between KAP (knowledge, attitude, and practices) and different socio-demographic variables. Binary logistic regression was performed to identify and control the confounding factors. Data were analyzed using SPSS (version 22). Results: A total of 665 students have completed the online questionnaire. The mean age was 20.55 ± 3.069 years. Multivariate analysis revealed that males, students from health professions and scientific faculties, and those with highly educated parents had manifested a good knowledge level (GKL) about COVID-19. With regard to students' practices, fewer negative practices were displayed by students from health professions faculty and the students living at the middle governorate of Palestine, compared to north, south, and Jerusalem dwellers. With regard to the practices, the vast majority of the participants showed a positive and very cautious practice in relation to the COVID-19 epidemic. Conclusion: Our results revealed that students had variable knowledge about COVID-19, and the vast majority depended on the official media briefs in Palestine as a source of information. With regard to practices, positive and cautious practices with regard to the COVID- 19 epidemic were carried out by the vast majority of participants.
RESUMEN
PURPOSE: Clostridioides difficile is one of the most important nosocomial infection pathogens. It is linked with many risk factors. Unfortunately, many studies have been conducted in different countries to address the Clostridioides difficile infections (CDI), and no studies have been conducted in Palestine. This study aims to identify the prevalence and possible risk factors associated with CDI. PATIENTS AND METHODS: This was a retrospective descriptive study conducted at the An-Najah National University Hospital (NNUH) in Palestine. Data were collected for patients diagnosed with CDI who tested positive for GDH, toxins A and B between January 2018 and April 30, 2021. In addition, patient characteristics and risk factors associated with CDI were analyzed. RESULTS: A total of 593 participants were included in the study; 53% had hospital-acquired CDI. There was an insignificant association between participant age and CDI risk. Most patients had mild to moderate infections. Sixty-three percent of the participants were immunocompromised. About 58.5% used an antibiotic agent two weeks before CDI, and 67% were on a proton pump inhibitor (PPI). About 61.3% of patients were treated according to IDSA 2017 guidelines, and 94% responded adequately to the treatment provided. CONCLUSION: There was an increased prevalence of community-acquired CDI, with a prevalence almost equal to that of hospital-acquired. In addition, most of the participants were immunocompromised. The risk factors for CDI, such as antibiotics and PPI use, were also observed with high prevalence among positive patients. Antimicrobial stewardship and the appropriate use of acid suppressors are warranted.
