RESUMEN

BACKGROUND: The COVID-19 pandemic highlights vaccination's critical role in reducing morbidity and mortality, depending on public attitude. This study aims to identify the estimates of COVID-19 vaccine acceptance in pregnant and lactating women, as well as associated potential factors. METHODS: A cross-sectional study was conducted between August and September 2021, through an online survey and with a paper survey distributed in gynecology and pediatric clinics. Pregnant and breastfeeding women aged 18 years and above were recruited. The attitude scale was created specifically for evaluating attitudes towards the COVID-19 vaccine. RESULTS: In total, 207 women participated, with 132 breastfeeding, 74 pregnant and 1 experiencing both conditions. Of these, one hundred and twenty women (58%) considered themselves at risk for COVID-19 infection. In addition, 51.7% (n = 107) of women expressed the intent to receive the vaccine once available. A multivariable linear regression was conducted taking the COVID-19 vaccination attitude scale as a dependent variable. The results revealed an R-squared value of 0.558, indicating that approximately 55.8% of the variance in the attitude scale was accounted for by the included predictors. The results showed that preventive measures (ß=2.25, 95% Confidence Interval (CI) [1.02; 3.48], p < 0.001), preference for vaccines made in Europe and America (ß=1.23; 95% CI [0.69-1.77], p < 0.001), protect yourself for getting sick (ß=4.22, 95% Confidence Interval (CI) [2.83; 5.61], p < 0.001) and belief in the importance of vaccination for themselves and their baby (ß=3.49; 95% CI [2.01; 4.98], p < 0.001) were associated with a positive attitude towards vaccination. Conversely, experiencing a previous bad reaction to a vaccine (ß= -1.35; 95% CI [0.85-1.85], p < 0.001) and concerns regarding COVID-19 vaccine safety (ß= -4.09; 95% CI [-5.98; -2.21], p < 0.001) were associated with a negative attitude towards vaccination. CONCLUSION: Our findings reveal that COVID-19 vaccine acceptability among pregnant and breastfeeding women, amidst the pandemic was insufficient to meet community immunity. The identified reasons for vaccine reluctance, notably concerns about safety for both personal health and the health of their pregnancy or newborns, along with insufficient information about the vaccine, underscore the pressing need to address these factors to improve immunization rates.

RESUMEN

BACKGROUND: Hypertensive disorders of pregnancy (HDPs) are responsible for most perinatal and fetal mortality. Few programs are patient-centered during pregnancy, thereby increasing the risks of misinformation and misconceptions among pregnant women and, as a result, malpractices. OBJECTIVE: This study aims to develop and validate a form to assess the knowledge and attitudes of pregnant women about HDPs. STUDY DESIGN: A cross-sectional pilot study was conducted over 4 months, targeting 135 pregnant women from 5 obstetrics and gynecology clinics. A self-reported survey was developed and validated, and an awareness score was generated. RESULTS: The mean maternal age of the participants was 27.3 (5.3) years. About 80% of the participants reported that they monitored their weight during pregnancy, and 70.4% monitored their blood pressure, out of which 73.8% performed it at the doctor's clinic only. Overall, participants had a total score of 16.9 (3.1) over 25 with higher attitude scores than knowledge scores. Less than half of the patients (45.2%) knew the cut-off for hypertension. With respect to knowledge statements, higher scores were noted for statements related to the symptoms of HDPs, and lower scores were reported for statements related to some HDP complications. Older women and those who monitored their blood pressure during pregnancy had significantly higher awareness scores. Those working had higher awareness of HDPs (67.4%), whereas about half of nonworkers (53.9%) showed lower awareness scores (P=.019). CONCLUSION: Pregnant women had moderate awareness of HDPs. The short 25-item tool developed in the present study can be used in obstetric clinics to explore the awareness of women of HDPs.

RESUMEN

Background: Community pharmacists played an essential role in the control and management of the COVID-19 pandemic; both pharmaceutical care and community pharmacists were affected, given that, patients' needs and demands increased due to the fear of lockdowns and shortage of medication throughout the pandemic. Objectives: This study was based in Lebanon and aimed to assess the impact of the COVID-19 pandemic on (1) pharmacists, including infection rates, pay, and working hours, and (2) pharmacy practice, including medicine and personal protective equipment (PPE) shortages. Design: A cross-sectional study involving 120 community pharmacists was carried out between August and November 2021. Methods: Data were collected using an online survey filled out by pharmacists working in Lebanon. Results: Most participants (71.7%) reported an increase in their income during the pandemic, and 60% reduced their working hours. A significant association was noted between being previously infected and marital status, level of education, work position, and salary of the participants. Most participants (95.8%) encountered a shortage of medications during the pandemic leading to high home storage of medication, searching for other sources of medicines, and decreased patient/pharmacist interactions. Conclusion: The COVID-19 pandemic imposed new challenges on pharmacists and the provision of pharmaceutical care. It affected pharmacists' daily routines, putting them at risk of infection with limited availability of medicines and PPE. This study suggests that establishing effective crisis management plans to increase community pharmacists' resilience during similar outbreaks.

RESUMEN

BACKGROUND: Home confinement and lockdowns have created challenges and vulnerabilities, causing relevant changes in sexual health and couple stability, particularly in women. The objective of this study was to evaluate the socio-economic and psychological factors related to current pregnancy status and unwanted pregnancy among Lebanese women during the COVID-19 lockdown. METHODS: A cross-sectional online study conducted between June 8 and August 1, 2020, enrolled 369 Lebanese women using the snowball technique for data collection. All married women between 18 and 51, with access to the internet and currently living with their partners, were eligible to participate. Current pregnancy status and unwanted pregnancy were assessed using binary questions. The SPSS software 25 was used for data analysis, and multivariable analysis was performed, taking the pregnancy status and unwanted pregnancy as the dependent variables. The statistical significance was set at a p-value < 0.05. RESULTS: Our results showed that 11.1% of women were pregnant, of whom 22.0% reported unwanted pregnancies. Having children (ORa = 0.183) and taking contraceptives (ORa = 0.231) were significantly associated with a reduced chance of becoming pregnant. Higher psychological violence would negatively affect pregnancy, but the association was not significant (p = 0.065). Regular visits to the physician for routine checks were also linked to a decreased risk of unwanted pregnancy (ORa = 0.053). Higher psychological violence would affect unwanted pregnancy; however, the association was insignificant (p = 0.056). CONCLUSION: The study findings showed that having children and taking contraceptives are associated with a reduced pregnancy. Additionally, psychological violence was found to be related to current pregnancy status and unplanned pregnancy. During a pandemic, vulnerable women should be identified and given adequate care, knowledge, and awareness regarding their reproductive health.

RESUMEN

INTRODUCTION: Since the majority of cancers occur as a result of modifiable risk factors, cancer is being seen more as a preventable disease. The primary objective of our study was to assess the level of awareness of environmental risk factors of cancer among the Lebanese general population. The secondary objective focused on identifying the predictors of the preventability of the disease. METHODS: We conducted a cross-sectional study between June and July 2020. An online questionnaire was used to collect data pertaining to the knowledge of environmental risk factors of cancer, source of information and personal practice of the participants. Bivariate and multivariate analyzes were performed. RESULTS: About 387 respondents agreed to participate in the study. The study showed low awareness regarding infectious agents, lifestyle, diet and many work exposures. The predictors of the attitude of respondents regarding the preventability of cancer were: believing that cancer has an environmental cause (p=.014), not having a healthy lifestyle (p = 0.004), not smoking waterpipe (p = 0.023), being single (p = 0.013), and having a university degree (p = 0.049). CONCLUSIONS: Efforts should be made to improve awareness of the cancer risk factors regarding infectious agents, lifestyle, diet and many work exposures. This can also be followed by further studies assessing the impact of these community and governmental cancer prevention initiatives on cancer risk factors level of awareness.

RESUMEN

BACKGROUND: Autonomy involves making independent decisions and creating lasting and equitable power relationships within families. Many factors, dependent on both the woman and her partner, can influence self-dependence, and subsequent decision-making, exerting a protective or triggering effect on its development. Therefore, the primary objective of the study was to assess autonomy in a sample of Lebanese women. The secondary objective was to evaluate the association between socioeconomic status, psychological factors, and autonomy. METHODS: A web based cross-sectional online study was conducted between June 8 and August 1, 2020. The questionnaire developed on Google Forms was distributed through social media and WhatsApp groups, using the snowball technique. The Women's Autonomy Index (WAI) was created using three items adapted from a previous study. In addition, the Composite Abuse Scale Revised-Short Form (CASR-SF) was used to assess three domains of abuse: physical, sexual, and psychological. The Perceived stress scale short version to measure stress perception, the Lebanese Anxiety Scale to measure anxiety and the Patient Health Questionnaire (PHQ-9) to assess depression. The Statistical Package for the Social Sciences (SPSS) software version 25 was used for data analysis. Linear regressions were performed, taking the Women's Autonomy Index as the dependent variable. RESULTS: The sample consisted of 369 Lebanese women. University education level (beta = 1.263), alcohol consumption (beta = 0.586), intermediate income level (beta = 0.702), high income (beta = 0.911), employment (beta = 0.559), and older age (beta = 0.033) were significantly associated with higher WAI. Living in South Lebanon (beta = - 0.668) and being Druze (beta = - 323) were associated with lower WAI. Significantly higher mean scores of anxiety and perceived stress were found among women with low autonomy. CONCLUSION: In Lebanon, the autonomy of women depends on several personal and partner-related characteristics (education, socioeconomic status, age), in addition to the cultural (geographic and religious) environment. Furthermore, low autonomy is associated with higher perceived stress and anxiety and probable depression and domestic abuse.

RESUMEN

BACKGROUND: Hospital readmissions are considered as the primary indicator of insufficient quality of care and are responsible of increasing annual medical costs by billions of dollars. Different factors tend to reduce readmissions, particularly instructions at discharge. OBJECTIVES: Our study objective was to evaluate discharge instructions given to hospitalized Lebanese patients and associated factors. METHODS: Two hundred patients, aged between 21 and 79 years and admitted to the emergency department, were recruited from a Lebanese university hospital. Discharge instructions were evaluated by a face-to-face interview to fill a questionnaire with the patients immediately after their final contact with the physician or nurse in charge. We mainly focused on medications instructions and created two scores related to "instructions given" and "instructions appropriate" to later conduct bivariate analysis. RESULTS: We found that discharge instructions were not completely given to all our study population. The degree of appropriateness fluctuated between 25% and 100%. The instructor in charge of giving discharge instructions had its significant influence on medication instructions given (p=0.014). In addition, the instructor and his experience influenced the degree of "appropriate instructions". In fact, our study showed that despite being capable of giving good medication advice, nurses' instructions were significantly less effective in comparison with physicians, fellows and residents. However, nurses gave 52% of the instructions, which questions the quality of those instructions. CONCLUSIONS: In conclusion, our observational study showed that in a Lebanese university hospital, patients' understanding of discharge instructions is poor. Careful attention should be drawn to other hospitals as well and interventions should be considered to improve instructions quality and limit later complications and readmissions. The intervention of clinical pharmacists and their medication-related advice might be crucial in order to improve instructions' quality.

RESUMEN

The purpose of this study was to develop a whole-body physiologically based pharmacokinetic (WB-PBPK) model for ciprofloxacin for ICU patients, based on only plasma concentration data. In a next step, tissue and organ concentration time profiles in patients were predicted using the developed model. The WB-PBPK model was built using a non-linear mixed effects approach based on data from 102 adult intensive care unit patients. Tissue to plasma distribution coefficients (Kp) were available from the literature and used as informative priors. The developed WB-PBPK model successfully characterized both the typical trends and variability of the available ciprofloxacin plasma concentration data. The WB-PBPK model was thereafter combined with a pharmacokinetic-pharmacodynamic (PKPD) model, developed based on in vitro time-kill data of ciprofloxacin and Escherichia coli to illustrate the potential of this type of approach to predict the time-course of bacterial killing at different sites of infection. The predicted unbound concentration-time profile in extracellular tissue was driving the bacterial killing in the PKPD model and the rate and extent of take-over of mutant bacteria in different tissues were explored. The bacterial killing was predicted to be most efficient in lung and kidney, which correspond well to ciprofloxacin's indications pneumonia and urinary tract infections. Furthermore, a function based on available information on bacterial killing by the immune system in vivo was incorporated. This work demonstrates the development and application of a WB-PBPK-PD model to compare killing of bacteria with different antibiotic susceptibility, of value for drug development and the optimal use of antibiotics .

RESUMEN

OBJECTIVES: To explore different ciprofloxacin dosage regimens for the treatment of intensive care unit (ICU) patients with respect to clinical outcome and the development of bacterial resistance for the major Gram-negative pathogens. METHODS: A population pharmacokinetic model was first developed on ciprofloxacin serum concentrations obtained in 102 ICU patients. Then, based on this model, pharmacokinetic-pharmacodynamic Monte Carlo simulations (MCSs) were carried out to explore the appropriateness of different ciprofloxacin dosage regimens in ICU patients. The defined targets were free AUC(24)/MIC ≥90 h (as a predictor of clinical outcome) and T(MSW) ≤20% (as a predictor of selecting resistance), where T(MSW) is the time spent within the mutant selection window over 24 h. Two simulation trials were conducted: Trial 1 took into account the whole MIC distribution for each causative pathogen in line with empirical antibiotherapy; Trial 2 used MIC breakpoints given by the Antibiogram Committee of the French Microbiology Society in order to treat the 'worst-case' scenario. RESULTS: Trial 1 showed that for Pseudomonas aeruginosa and Acinetobacter baumannii, the common dosage regimens of 400 mg twice or three times a day did not achieve the desired target attainment rates (TARs) with respect to T(MSW), while suboptimal TARs were found for AUC(24)/MIC. Trial 2 showed that ≤ 18% of patients reached the target of T(MSW) ≤ 20% for MIC breakpoints of 0.5 and 1 mg/L, regardless of the administered dose. CONCLUSIONS: Based on the mutant selection window concept, our simulations truly question the use of ciprofloxacin for the treatment of P. aeruginosa and A. baumannii infections in ICU patients due to the potential for developing resistance.

RESUMEN

Diagnostic and interventional radiology of patients is nowadays crucial with increasing requirement for iodinated contrast agents infusion. Besides adverse reactions after administration of the iodinated contrast agents due to their toxicity, immediate hypersensitivity reactions and reactions resembling delayed hypersensitivity appearing from 1 hour to several days later, have been reported. Patients at high risk to develop such adverse events have to be detected on the basis of their risk factors in order to prevent or limit serious outcomes. Previous reactions to contrast media, asthma, atopy and cardiovascular disorders are risk factors for anaphylactic or anaphylactoid reactions. Female gender, age and beta-blockers increase the severity. This article aims to summarize the risk of allergic reactions related to the use of iodinated contrast agents and to suggest a way for diagnosis, treatment and prevention according to each clinical situation.

RESUMEN

Ischemic postconditioning (IPost) and erythropoietin (EPO) have been shown to attenuate myocardial reperfusion injury using similar signaling pathways. The aim of this study was to examine whether EPO is as effective as IPost in decreasing postischemic myocardial injury in both Langendorff-isolated-heart and in vivo ischemia-reperfusion rat models. Rat hearts were subjected to 25 min ischemia, followed by 30 min or 2 h of reperfusion in the isolated-heart study. Rats underwent 45 min ischemia, followed by 24 h of reperfusion in the in vivo study. In both studies, the control group (n=12; ischemia-reperfusion only) was compared with IPost (n=16; 3 cycles of 10 s reperfusion/10 s ischemia) and EPO (n=12; 1,000 IU/kg) at the onset of reperfusion. The following resulted. First, in the isolated hearts, IPost or EPO significantly improved postischemic recovery of left ventricular developed pressure. EPO induced better left ventricular developed pressure than IPost at 30 min of reperfusion (73.18+/-10.23 vs. 48.11+/-7.92 mmHg, P<0.05). After 2 h of reperfusion, the infarct size was significantly lower in EPO-treated hearts compared with IPost and control hearts (14.36+/-0.60%, 19.11+/-0.84%, and 36.21+/-4.20% of the left ventricle, respectively; P<0.05). GSK-3beta phosphorylation, at 30 min of reperfusion, was significantly higher with EPO compared with IPost hearts. Phosphatidylinositol 3-kinase and ERK1/2 inhibitors abolished both EPO- and IPost-mediated cardioprotection. Second, in vivo, IPost and EPO induced an infarct size reduction compared with control (40.5+/-3.6% and 28.9+/-3.1%, respectively, vs. 53.7+/-4.3% of the area at risk; P<0.05). Again, EPO decreased significantly more infarct size and transmurality than IPost (P<0.05). In conclusion, with the use of our protocols, EPO showed better protective effects than IPost against reperfusion injury through higher phosphorylation of GSK-3beta.

RESUMEN

The objective of this study was to evaluate the properties of ciprofloxacin in intensive care patients using a population approach. Seventy patients received ciprofloxacin. On Day 1, three to eight blood samples were taken over a 12-h period. Peak drug concentration (Cmax) and 24-h area under the concentration-time curve (AUC) were compared with the French breakpoint defining antibiotic susceptibility. A population pharmacokinetic modelling approach was then carried out. A two-compartment open model with a proportional error model best fitted the data. A relationship between the elimination constant rate and the Cockcroft creatinine clearance was found. Ciprofloxacin clearance was 13.6+/-5.8L/h, the volume of distribution was 62.0+/-10.7 L and the ciprofloxacin half-life was 3.7+/-1.8h. When the minimum inhibitory concentration (MIC) was equal to 1mg/L the inhibitory ratio (IR) was > or = 8 in only 10.8% of cases, and the AUC/MIC ratio (AUIC) was 42.0+/-36. In conclusion, this study highlights that the Cockcroft clearance significantly influences ciprofloxacin elimination. Target plasma concentrations for ciprofloxacin, the IR and AUIC were rarely reached with a standard dosing regimen. In critically ill patients, the observed pharmacokinetic variability is mainly responsible for the overly frequent low concentrations of ciprofloxacin, emphasising the need for therapeutic monitoring.
