Influence of Health Literacy on Medication Adherence Among Elderly Females With Type 2 Diabetes in Pakistan.

Health literacy is how well the patients are able to attain, deal with, and understand basic health information. This is particularly important when it comes to comprehending prescribed medication instructions. To improve the communication strategies for health-care professionals during patient counseling, our study aimed to assess the influence of health literacy and medication adherence in older patients. The objectives of the study were to evaluate associations that occur between the level of health literacy and medication adherence. This study used a convenience sampling method of females (older than 60 years) attending the diabetic clinic in two hospital settings (N = 524). All study participants filled three validated questionnaires: these were the Literacy Assessment for Diabetes, the Diabetes Numeracy Test, and a modified Brief Adherence Rating Scale. To assess the spectrum of health literacy differences, we used χ2 analysis and linear regression analysis. Individuals with adequate health literacy were more likely to remember to take their medications compared with those with inadequate health literacy, χ2(4) = 11.6, p = .04. Adequate literacy level study participants were more likely to not change the dose of their medications without medical advice (12.3%) compared with those individuals with inadequate health literacy (2.8%), χ2(4) = 11.13, p = .03. The results in our study suggest that health-care professionals should focus on appropriate communication attuned to the assessment of health literacy levels particularly in older female patients when discussing medication instructions.

Inhaled salbutamol dose delivered by jet nebulizer, vibrating mesh nebulizer and metered dose inhaler with spacer during invasive mechanical ventilation.

BACKGROUND: Patient receiving invasive mechanical ventilation (IMV) may benefit from medical aerosol, but guidance on dosing with different aerosol devices is limited to in-vitro studies. The study was designed to compare aerosol delivery with five different types of aerosol generators during IMV. METHOD: In randomized design, 60 (30 female) mechanically ventilated chronic obstructive pulmonary disease (COPD) patients were assigned to one of 5 groups. Groups 1-4 received 5000 µg salbutamol using Aerogen Pro (PRO), Aerogen Solo (SOLO), NIVO vibrating mesh and jet nebulizers (JN), respectively, while group 5 received 800 µg (8 puffs) of salbutamol via metered dose inhaler with AeroChamber-MV (MDI-AC). All devices were place in the inspiratory limb of ventilator downstream from humidifier which was switched off while delivery. Patients received the inhaled dose on day 1 and provided urine 30 post dosing. They also recived the same inhaled dose with a filter before the endotracheal tube on day 2. Amount of salbutamol excreted in urine 30 min post inhalation and the amount deposited on the filter from all the COPD patients were determined as indeces of pulmonary deposition and systemic absorption, respectively. RESULTS: No significant difference was found between the 3 vibrating mesh nebulizers (VMNs). The in-vivo and ex-vivo testing showed that all the VMNs resulted in better aerosol delivery compared to JN (p < 0.01). However, MDI-AC resulted in better aerosol delivery to VMNs but must be accompanied with careful attention and proper delivery of MDI-AC doses by healthcare provider. CONCLUSIONS: VMNs can be exchanged with each other, with no dose adjustment. However, dose adjustment is a must when replacing VMNs by JN or MDI-AC. This similarity and difference between the 5 aerosol delivery methods suggest that for IMV patients, aerosol delivery methods should be chosen or substituted with care.

ERCC1 and ERCC2 as predictive biomarkers to oxaliplatin-based chemotherapy in colorectal cancer patients from Egypt.

BACKGROUND: The impact of Excision repair cross-complementation group 1 (ERCC1) and group 2 (ERCC2) expression levels on the efficacy of oxaliplatin-based chemotherapy is still controversial. The present study was conducted to determine the predictive value of these molecular biomarkers in stage III and IV colorectal cancer (CRC) patients receiving oxaliplatin (OX)-based chemotherapy as first-line treatment. METHODS: The study included 80 CRC patients who received first line oxaliplatin based chemotherapy The expression levels of ERCC1 and ERCC2-mRNA and proteins were determined in the primary tumors by quantitative real time reverse transcription polymerase chain reaction(RT-qPCR) and immunohistochemistry (IHC); respectively. The results of mRNA expression were correlated with patients' characteristics, response to treatment, overall- and event free survival (OS & EFS). RESULTS: Sixty four out of the 80 patients were legible for assessment of ERCC1 and ERCC2 expression. The cut-off levels of ERCC1and ERCC2-RNA were 3.8×10-3& 4.6×10-3; respectively. Reduced ERCC1 and ERCC2 RNA expressions were detected in 50 (78.1%) and 48 (75%) cases, respectively whereas reduced proteins were detected in 48 cases (75%) for ERCC1 and ERCC2. After The median follow up period was 30.5months (range: 7-104months), Patients with low mRNAERCC1levels showed significantly longer OS (p=0.011) and EFS (p˂0.001). However, no significant relation was found between ERCC2 levels and OS or EFS. In multivariate analysis performance status (PS), stage of the disease and ERCC1-mRNA expression were independent prognostic factors for EFS whereas tumor histology and stage of the disease were independent factors for OS. CONCLUSIONS: ERCC1 expression levels may help in selecting patients who benefit from oxaliplatin chemotherapy in stage III & IV CRC. Further large trials are needed to validate these data.

In vitro/in vivo correlation and modeling of emitted dose and lung deposition of inhaled salbutamol from metered dose inhalers with different types of spacers in noninvasively ventilated patients.

Substituting spacer by another in noninvasive ventilation (NIV) involves many variables, e.g. total emitted dose (TED), mass median aerodynamic diameter (MMAD), type of spacer, total lung deposition and total systemic absorption, which must be adjusted to ensure patient optimum therapy. Data mining based on artificial neural networks and genetic algorithms were used to model in vitro inhalation process, predict and optimize bioavailability from inhaled doses delivered by metered dose inhaler (MDI) using different spacers in NIV. Modeling of data indicated that in vitro performance of MDI-spacer systems was dependent mainly on fine particle dose (FPD), fine particle fraction (FPF), MMAD and to lesser extent on spacer type. Ex vivo model indicated that amount of salbutamol collected on facemask filter was directly affected by FPF. In vivo model (24hQ) depended directly on spacer type, FPF and TED. Female patients showed higher 0.5hQ and 24hQ values than males. AeroChamber VC spacer demonstrated higher TED and 24hQ in vivo values. Results indicated suitability of MDI-spacer systems in achieving appropriate in vitro inhalation performance. The possibility of modeling and predicting both ex vivo and in vivo capabilities of MDI-spacer systems from knowledge of in vitro attributes enabled detailed focus on important variables required to deliver safe and accurate doses of salbutamol to ventilated patients.

In vitro aerodynamic characteristics of aerosol delivered from different inhalation methods in mechanical ventilation.

Aerodynamic characteristics of aerosol delivery during invasive mechanical ventilation (IMV) are mostly determined by inserting cascade impactor in the circuit. Impactor might have some effect on airflow within IMV. Hence, the aim of the present study was to develop and evaluate new in vitro aerodynamic characterization methodology without affecting airflow in IMV. Breathing simulator was set in standard adult IMV circuit with inspiratory and expiratory pressures of 20 and 5 cm H2O, 1:3 inspiratory-expiratory ratio, 15 breaths min-1, and tidal volume of 500 ml. Two ml of salbutamol solution containing 10,000 µg was nebulized using three different vibrating mesh nebulizers (VMNs) and Sidestream jet nebulizer (JET). Sixteen-metered doses, containing 100 µg salbutamol each, were delivered using three different spacers. Each device was placed in inspiration limb of Y-piece of ventilator tubing. Aerodynamic characteristics of aerosol delivered were measured using cooled Andersen cascade impactor, with mixing inlet connected to it. VMNs used had significantly more total mass in the impactor (p < .001) and fine particle dose (p < .001) compared to JET. Spacers used had higher total mass in the impactor percent (p < .001) and fine particle fraction compared to nebulizers. The in vitro IMV methodology setting suggested here showed encouraging results in comparison of different aerosol delivery systems in intubated patient.

Adverse Drug Reaction Reporting Practices Among United Arab Emirates Pharmacists and Prescribers.

Background: Underreporting of adverse drug reactions (ADRs) has placed a heavy financial burden on health care resources worldwide. Realizing the importance of proper ADR reporting is paramount for implementing better patient care. Objective: This study was designed to assess knowledge, attitude, and practice (KAP) of ADR reporting among United Arab Emirates (UAE) health care professionals to clarify their present strategies and identify steps to avoid underreporting. Methods: A self-administered cross-sectional questionnaire was designed and randomly distributed to different health care personnel (n = 150). All participants were briefly informed about the aim of the study and given sufficient time to respond. The responses were collected over 6 months. The data were statistically analyzed for each reporter category (community pharmacist, hospital pharmacist, and doctors) using the chi-square test. Results: We found that 81%, 83%, and 83.3% of doctors, community pharmacists, and hospital pharmacists, respectively, were not aware of the existence of a reporting center and 56%, 60%, and 72% were not aware of a reporting procedure. Poor ADR reporting practices were shown by responders; only 19%, 14%, and 12.1% of doctors, community pharmacists, and hospital pharmacists reported ADRs. Conclusion: This study showed poor KAP results among health care professionals. Proper educational intervention strategies should be established in different health care settings for better patient care. With proper guidance, objectives in all health care settings should be targeted to positively change the concept of health care to consider ADR reporting as a common accepted daily routine practice.

Predictors of methotrexate adherence and patient's awareness of it in rheumatoid arthritis and its effect on quality of life.

Introduction: Adherence studies among rheumatoid arthritis (RA) patients, in Egypt and throughout the Middle East region, are lacking. This study aimed to evaluate methotrexate (MTX) adherence in Rheumatoid arthritis (RA) patients and to identify specific non-adherence predictors. Methods: A cross-sectional observational study included 300 RA patients who were administered MTX for at least one year. The survey was completed through direct interviews. The demographic patient data were collected (age, education, sex, work status, disease duration, duration of MTX administration and current dose). Patients' adherence to MTX predictors for non-adherence, MTX side effects and functional disability were assessed in the study. Results: Majority of respondents showed good MTX adherence, and more than 50% of patient's experienced MTX side effects. A large percentage of participants showed low knowledge about MTX nature and side effects. Most participants reported no or some difficulty in quality of life-related activities and functional disability. Conclusion: MTX adherence and awareness were positively correlated to many variables, including, age, educational level and disease duration, which in turn has its positive impact on the patient's quality of life. Still, more research is needed to determine the impact of non-adherence on the patient's health outcomes.

Monotherapy versus polytherapy of enoxaparin and hydroxychloroquine for the treatment of COVID-19: A randomized controlled clinical trial.

Objectives: The current study aims to assess the efficacy and safety of Enoxaparin and hydroxychloroquine (HCQ) used as monothrapy or polytherapy versus standard care alone in Coronavirus 2019 (COVID-19) infected patients. Methods: The current study included two hundred patients with laboratory confirmed COVID-19 infection. Patients admitted to hospital were randomly allocated into four groups: group I: received standard COVID-19 therapy, group II: received Enoxaparin 40mg/day subcutaneously (SC) plus standard therapy, group III: received 400 mg/day HCQ plus standard therapy & group IV: received a combination of 400 mg/day HCQ and Enoxaparin plus standard COVID-19 therapy. The disease progression was evaluated by duration to a negative polymerase chain reaction (PCR), length of hospital or Intensive Care Unit (ICU) stay, and mortality rate. The safety of treatments was evaluated by measuring adverse effects. Results: The length of hospital stay, ICU admission and mortality were significantly decreased in Enoxaparin plus standard COVID-19 therapy group versus other groups. Conclusion: These findings suggest that Enoxaparin was safe, effective, and well tolerated and has a role in decreasing the progression of the disease and its complications while HCQ did not discover any evidence of extra therapeutic benefits.

Identification of NS2B-NS3 Protease Inhibitors for Therapeutic Application in ZIKV Infection: A Pharmacophore-Based High-Throughput Virtual Screening and MD Simulations Approaches.

Zika virus (ZIKV) pandemic and its implication in congenital malformations and severe neurological disorders had created serious threats to global health. ZIKV is a mosquito-borne flavivirus which spread rapidly and infect a large number of people in a shorter time-span. Due to the lack of effective therapeutics, this had become paramount urgency to discover effective drug molecules to encounter the viral infection. Various anti-ZIKV drug discovery efforts during the past several years had been unsuccessful to develop an effective cure. The NS2B-NS3 protein was reported as an attractive therapeutic target for inhibiting viral proliferation, due to its central role in viral replication and maturation of non-structural viral proteins. Therefore, the current in silico drug exploration aimed to identify the novel inhibitors of Zika NS2B-NS3 protease by implementing an e-pharmacophore-based high-throughput virtual screening. A 3D e-pharmacophore model was generated based on the five-featured (ADPRR) pharmacophore hypothesis. Subsequently, the predicted model is further subjected to the high-throughput virtual screening to reveal top hit molecules from the various small molecule databases. Initial hits were examined in terms of binding free energies and ADME properties to identify the candidate hit exhibiting a favourable pharmacokinetic profile. Eventually, molecular dynamic (MD) simulations studies were conducted to evaluate the binding stability of the hit molecule inside the receptor cavity. The findings of the in silico analysis manifested affirmative evidence for three hit molecules with -64.28, -55.15 and -50.16 kcal/mol binding free energies, as potent inhibitors of Zika NS2B-NS3 protease. Hence, these molecules holds the promising potential to serve as a prospective candidates to design effective drugs against ZIKV and related viral infections.

COVID-19's Psychological Impact on Chronic Disease Patients Seeking Medical Care.

BACKGROUND: The outbreak has harmed patients with multiple comorbidities and chronic conditions. The pandemic's psychological impact is thought to change their routine of seeking medical care. Research Question or Hypothesis: During COVID-19, patients with chronic conditions may experience anxiety, depression, and stress, and their pattern of seeking medical care may change. MATERIALS AND METHODS: In May 2021, a cross-sectional, web-based study of patients with chronic diseases was conducted. Eligible patients (1036) were assessed for psychological disorders, primarily depression, stress, and anxiety, using the DASS-21 scale, and their pattern of receiving medical care during COVID-19. RESULTS: During the pandemic, 52.5% of the patients with chronic diseases were depressed, 57.9% were anxious, and 35.6% were stressed. Patients with chronic diseases who had moderate to severe depression (34.9% versus 45.1%, p = 0.001), moderate to severe anxiety (43.6% versus 53.8%, p = 0.001), or moderate to severe stress (14.9% versus 34.8%, p = 0.001) were significantly more likely to have no follow-up for their chronic conditions. CONCLUSIONS: Patients with chronic conditions experienced significant anxiety, depression, and stress during COVID-19, which changed their pattern of seeking medical care, and the majority of them did not receive follow-up for their chronic conditions.

Macrophages M2 polarization is involved in lapatinib-mediated chemopreventive effects in the lung cancer.

M2 polarized tumor-associated macrophages (TAMs) have a multifunctional role in cancer initiation, progression, metastasis, and contribute to chemotherapeutic resistance. Therefore, identifying M2 polarized TAMs is a potential target for cancer therapeutic intervention. The underlying mechanism that target the TAMs M2 polarized macrophages remains primarily uncharacterized; however, only a few compounds have been identified that inhibit TAMs M2 polarized macrophages. In this research, we investigated that lapatinib could effectively suppress the expression of IL_13-induced M2 polarized macrophages surface markers i.e., CD163 and CD206, and downregulation of M2 genes such as Fizz1, Mrc1, Arg1, IL-10, Ym1, nd CCL2 in vitro. Moreover, lapatinib abrogated the M2 polarized macrophage-mediated cancer cells invasion and migration. Mechanistically, in our study, lapatinib inhibited IL-13 triggered STAT6 phosphorylation. Furthermore, in LLCs tumor model, lapatinib significantly reduced tumorigenesis, followed by the downregulation of percentages of M2 marker CD206+ and CD68+ in the tumor. This downregulation correlates with chemopreventive effect of lapatinib. All taken together, these results demonstrated that lapatinib effectively prevents the macrophage M2 polarization and indicates a potential mechanism for preventing the tumor growth via M2 polarized polarization intervention.

A Comparison of 3D Conformal and Deep Inspiratory Breath Holding vs. 4D-CT Intensity-Modulated Radiation Therapy for Patients with Left Breast Cancer.

BACKGROUND: Multimodality is required for the treatment of breast cancer. Surgery, radiation (RT), and systemic therapy were traditionally used. Pharmacotherapy includes different drug mechanisms, such as chemotherapy, hormone therapy, and targeted therapies, alone or in combination with radiotherapy. While radiation offers numerous benefits, it also has certain harmful risks. such as cardiac and pulmonary toxicity, lymphedema, and secondary cancer. Modern radiation techniques have been developed to reduce organs at risk (OAR) doses. MATERIALS AND METHODS: This study is a prospective feasibility trial conducted at the Fayium Oncology Center on patients with left breast cancer receiving adjuvant locoregional radiotherapy after either breast conservative surgery (BCS) or modified radical mastectomy (MRM). This study aimed to assess the proportion of patients who are fit both physically and intellectually to undergo breast radiotherapy using the deep inspiratory breath-holding (DIBH) technique, comparing different dosimetric outcomes between the 3D dimensional conformal with DIBH and 4D-CT IMRT plans of the same patient. RESULTS: D95 of the clinical target volume (CTV) of the target is significantly higher in the 3D DIBH plan than in the IMRT plan, with an average of 90.812% vs. 86.944%. The dosimetry of the mean heart dose (MHD) in the 4D-CT IMRT plan was significantly lower than in the 3D conformal with the DIBH plan (2.6224 vs. 4.056 Gy, p < 0.0064), and no significant difference between the two plans regarding mean left anterior descending artery (LAD) (14.696 vs. 13.492 Gy, p < 0.58), maximum LAD (39.9 vs. 43.5 Gy, p < 0.35), and V20 of the ipsilateral lung (18.66% vs. 16.306%, p < 0.88) was observed. Internal mammary chain (IMC) irradiation was better in the 4D-CT IMRT plan. CONCLUSIONS: Radiotherapy of the breast and chest wall with the 4D-CT IMRT technique appears not to be inferior to the 3D conformal with the DIBH technique and can be used as an alternative to the 3D conformal with the DIBH technique in patients meeting the exclusion criteria for performing the DIBH maneuver concerning coverage to target volumes or unacceptably high doses to OAR.

Clinical Consequences for Individuals Treated with Tocilizumab for Serious COVID-19 Infection.

There seem to currently be no therapeutic medications found for the severe coronavirus infection in 2019 (COVID-19). In light of this, it has been hypothesized that the immunomodulatory treatment known as tocilizumab can lessen the inflammatory response that occurs in the respiratory system, speed up the process of clinical benefit, lower the risk of death, and avert the need for ventilators. This randomized controlled trial (RCT) studied patients with a proven infection of SARS-CoV-2 and hyperinflammatory reactions. The inclusion criteria included fever (body temperature > 38 °C), pulmonary infiltrates, or supplemental oxygen. The patients received either conventional treatment with one dose of either tocilizumab (8 mg per kilogram of body weight) or conventional treatment only. The subjects were randomized to receive either treatment with a 1:1 ratio. A time-to-event test was conducted to determine the time to intubation or death. There was an insignificant difference between the investigated groups regarding the time to death, time to mechanical ventilation, and percentage of deaths. The conventional group's median (IQR) hospital length of stay was 4 (3-6) days, whereas the tocilizumab therapy group was 7 (4.75-10) days. There was a substantial difference in the mechanical ventilation rates in both groups, which were 17 (34%) and 28 (56%), respectively. In hospitalized patients with severe illness and COVID-19, tocilizumab was ineffective in preventing intubation or death. Trials must be larger, however, in order to exclude the potential benefits or harms.

COVID-19 Booster Doses: A Multi-Center Study Reflecting Healthcare Providers' Perceptions.

(1) Background: During 2019, the COVID-19 pandemic was threatening healthcare services and workers, and acquiring immunity was an option to stop or limit the burden of this pandemic. Herd immunity was a top priority worldwide as the virus was spreading rapidly. It was estimated that 67% of the total global population should be immunized against COVID-19 to achieve herd immunity. The aim of the current study is to investigate different perceptions of healthcare workers in the Kingdom of Bahrain and Egypt using an online survey in an attempt to evaluate their awareness and concerns regarding new variants and booster doses. (2) Methods: This study conducted a survey on healthcare workers in the Kingdom of Bahrain and Egypt about their perception and concerns on the COVID-19 vaccines. (3) Results: The study found that out of 389 healthcare workers 46.1% of the physicians were not willing to take the booster doses (p = 0.004). Physicians also did not support taking the COVID-19 vaccine as an annual vaccine (p = 0.04). Furthermore, to assess the association between the type of vaccine taken with the willingness of taking a booster vaccine, healthcare workers beliefs on vaccine effectiveness (p = 0.001), suspension or contact with patients (p = 0.000), and infection after COVID-19 vaccination (p = 0.016) were significant. (4) Conclusion: Knowledge about vaccine accreditation and regulation should be dispersed more widely to ensure that the population has a positive perception on vaccine safety and effectiveness.

Urinary pharmacokinetic methodology to determine the relative lung bioavailability of inhaled beclometasone dipropionate.

AIM: Urinary pharmacokinetic methods have been identified to determine the relative lung and systemic bioavailability after an inhalation. We have extended this methodology to inhaled beclometasone dipropionate (BDP). METHOD: Ethics Committee approval was obtained and all subjects gave consent. Twelve healthy volunteers received randomized doses, separated by >7 days, of 2000 µg BDP solution with (OralC) and without (Oral) 5 g oral charcoal, 10,100 µg inhalations from a Qvar(®) Easibreathe metered dose inhaler (pMDI) with (QvarC) and without (Qvar) oral charcoal and eight 250 µg inhalations from a Clenil(®) pMDI (Clenil). Subjects provided urine samples at 0, 0.5, 1, 2, 3, 5, 8, 12 and 24 h post study dose. Urinary concentrations of BDP and its metabolites, beclometasone-17-monopropionate (17-BMP) and beclometasone (BOH) were measured. RESULTS: No BDP, 17-BMP or BOH were detected in any samples post OralC dosing. Post oral dosing no BDP was detected in all urine samples and no 17-BMP or BOH was excreted in the first 30 min. Significantly more (P < 0.001) BDP, 17-BMP and BOH were excreted in the first 30 min and the cumulative 24 h urinary excretions post Qvar and Clenil compared with Oral. The mean ratio (90% confidence interval) of the 30 min urinary excretions for Qvar compared with Clenil was 231.4 (209.6, 255.7) %. CONCLUSION: The urinary pharmacokinetic methodology to determine the relative lung and systemic bioavailability post inhalation, using 30 min and cumulative 24 h post inhalation samples, applies to BDP. The ratio between Qvar and Clenil is consistent with related clinical and lung deposition studies.

Knowledge, attitude, and practice of pharmacists regarding asthma management: a cross-sectional study in Egypt.

BACKGROUND: Asthma is a significant public health issue that poses a substantial health and economic burden. Despite the availability of effective asthma medications, its management remain suboptimal. Recent asthma guidelines have highlighted the importance of pharmacist unique position and its interventional strategies in positively impacting asthma treatment outcomes. Therefore, this study aimed to assess the degree of Egyptian pharmacists' knowledge, attitudes, as well as their practices towards asthma management in line with the recent asthma guidelines. METHODS: This cross-sectional study was conducted among 800 pharmacists working in different private and governmental sectors. The data were collected using a 37-item pre-validated self-administered KAP questionnaire. The data were analyzed using Student's t-test and analysis of variance to assess the association between each KAP level and the sociodemographic variables at the significance level of 0.05. RESULTS: Of the 800 distributed questionnaire, a total of 550 participants (316 Male, and 234 Female) responded, representing a 68.7% response rate. The mean ± SD score of knowledge, attitude, practice, and barrier was 5.49 ± 1.65 (min = 0; max = 8), 23.5 ± 2.84 (min = 15, max = 30), 43.12 ± 8.61 (min = 28, max = 62), and 27.76 ± 3.72 (min = 17, max = 39), respectively. The results showed that poor knowledge, attitude, and practice scores were achieved by 30.54, 0, and 38.72% of participants, respectively. CONCLUSION: Our findings revealed the inconsistencies between poor pharmacists' knowledge and practices with respect to their positive attitudes. The lack of pharmacists' knowledge and compliance to recent GINA guidelines in this study highlight the crucial need for effective Educational strategies that should better equip pharmacists for their potential role in asthma care.

Menstrual symptoms variation among Lebanese women before and after the COVID-19 pandemic.

Objectives: Pandemic diseases and the confinement measures due to COVID-19 infection have introduced acute and persistent psychosocial stressors for different individuals with a greater influence on females manifested through changes in the menstrual cycle. The objective of this study was to assess Lebanese female of reproductive age about their menstrual cycle, their mental health, and their lifestyle, throughout the COVID-19 pandemic, Beirut blast, and the economic crises. Methods: A cross-sectional online study conducted between October and December 2021, enrolled 398 Lebanese women using the snowball technique. The Menstrual Symptom Questionnaire (MSQ) was used to assess menstrual symptoms. A repeated measures ANOVA was used to assess factors associated with the variation in MSQ scores after vs before the pandemic. Results: Our results showed that a significantly higher number of days of menses, number of pads per day and total MSQ score were significantly found after the pandemic compared to before it. More distress (Beta=0.68), more post-traumatic stress disorder due to COVID-19 (Beta=0.19), a higher number of waterpipes smoked per week (Beta=1.20) and being infected by COVID-19 compared to not (Beta=3.98) were significantly associated with an increase in the MSQ score after the pandemic compared to before it. Conclusion: Our main findings indicate that females had irregular menstrual cycles, unpredictable bleeding pattern, and intense symptoms severity post COVID-19 pandemic. Furthermore, stress post COVID-19 and Beirut blast tended to be associated with increased menstrual symptoms. Thus, vulnerable women should be identified and offered appropriate care, information, and awareness regarding their menstrual period during a pandemic.

Parents' Perception, Acceptance, and Hesitancy to Vaccinate Their Children against COVID-19: Results from a National Study in the UAE.

Introduction: COVID-19 is considered the greatest health disaster affecting humans during the 21st century, which urged the need to develop an effective vaccine to acquire enough immunity against the virus. The main challenge faced during the development of such vaccines was the insufficiency of time, which raised the question about the vaccine safety and efficacy, especially among children. Parents' and caregivers' thoughts and acceptance of administering the vaccine to their children are still debatable topics and are yet to be explored in the UAE. Aims: The study aims to exploit parent acceptance, perception, and hesitancy toward the COVID-19 vaccine administration for their children and the link with their choice of distance learning instead of face-to-face education in the UAE. Methodology: This study utilized a cross-sectional descriptive design. A sample of 1049 parents across all emirates were conveniently approached and surveyed using Google forms from June to September 2021. The participants responded to a semi-structured questionnaire pertaining to socio-demographic, educational, and other questions related to COVID-19 and its link with their beliefs in whether the vaccination of their children will help with resuming face-to-face learning. Results: Approximately 74% of the parents confirmed that their children who are 16 years old and above have received the vaccine, and 71% were willing to give the vaccine to their children aged above 5 years. Parents with children receiving online education and those with children where the online modality of learning negatively affected their academic achievement are more prone to administer the COVID-19 vaccine to their children above five years old. The results show a significant association between vaccination of children and the parental desire for resuming physical attendance in schools (p value < 0.001). Multivariate analysis showed that the highest acceptance rate was from parents with children of low academic achievement due to online learning modality during the pandemic. Conclusion: In the UAE, parents of young children have shown a positive attitude towards COVID-19 vaccination in belief that vaccines will reduce the risk of infection and assist in resuming normal lifestyles, such as going back physically to schools. The results reflect the public awareness and the hypervigilance regarding the COVID-19 pandemic in the UAE.

Nano Methotrexate versus Methotrexate in Targeting Rheumatoid Arthritis.

Nanomedicine has emerged as an important approach for targeting RA medication. Rheumatoid arthritis (RA) is a widespread autoimmune disorder marked by multiple inflamed joints. Gold nanoparticles (GNPs) have been demonstrated as efficacious nanocarriers due to their unique characteristics and the relative simplicity of their synthesis in varied sizes; moreover, they have the capability to alleviate several inflammatory markers. The current objective was to combine methotrexate (MTX) with GNPs to overcome MTX restrictions. GNPs were fabricated by a chemical reduction technique, utilizing sodium citrate and tween 20. The MTX-GNPs formulations were characterized in vitro by % entrapment efficiency (%EE), particle size, polydispersity index (PDI) zeta potential, and % release. The MTX-GNPs formulation was administrated as an intra-articular solution, and additionally, incorporated into a Carbopol gel to investigate its anti-arthritic effectiveness and bioavailability in vivo. The results indicated that a %EE of 87.53 ± 1.10%, and a particle size of 60.62 ± 2.41 nm with a PDI of 0.31 ± 0.03, and a zeta potential of −27.80 ± 0.36 mV were optimal. The in vitro release of MTX from the MTX-GNPs formulation demonstrated that the MTX-GNPs formulation's release was 34.91 ± 1.96% and considerably (p < 0.05) lower than that of free MTX, showing a significant difference in dissolution patterns (p < 0.05). In vivo, MTX-GNPs formulations inhibited IL-6 by 36.52%, ACCP (63.25 %), COMP (28.16%), and RANKL (63.67%), as well as elevated IL-10 by 190.18%. Transdermal MTX-GNPs decreased IL-6 by 22.52%, ACCP (56.63%), COMP (52.64%), and RANKL (79.5%), as well as increased IL-10 by 168.37%. Histological investigation supported these recent findings. Conclusions: Marked improvements in MTX anti-arthritic effects are seen when it is conjugated to GNPs.

Anti-inflammatory and anti-oxidant properties of Ipomoea nil (Linn.) Roth significantly alleviates cigarette smoke (CS)-induced acute lung injury via possibly inhibiting the NF-κB pathway.

Acute respiratory distress syndrome (ARDS), a serious manifestation of acute lung injury (ALI), is a debilitating inflammatory lung disease that is caused by multiple risk factors. One of the primary causes that can lead to ALI/ARDS is cigarette smoke (CS) and its primary mode of action is via oxidative stress. Despite extensive research, no appropriate therapy is currently available to treat ALI/ARDS, which means there is a dire need for new potential approaches. In our study we explored the protective effects of 70 % methanolic-aqueous extract of Ipomoea nil (Linn.) Roth, named as In.Mcx against CS-induced ALI mice models and RAW 264.7 macrophages because Ipomoea nil has traditionally been used to treat breathing irregularities. Male Swiss albino mice (20-25 ± 2 g) were subjected to CS for 10 uninterrupted days in order to establish CS-induced ALI murine models. Dexamethasone (1 mg/kg), In.Mcx (100 200, and 300 mg/kg) and normal saline (10 mL/kg) were given to respective animal groups, 1 h before CS-exposure. 24 h after the last CS exposure, the lungs and bronchoalveolar lavage fluid (BALF) of all euthanized mice were harvested. Altered alveolar integrity and elevated lung weight-coefficient, total inflammatory cells, oxidative stress, expression of pro-inflammatory cytokines (IL-1ß and IL-6) and chemokines (KC) were significantly decreased by In.Mcx in CS-exposed mice. In.Mcx also revealed significant lowering IL-1ß, IL-6 and KC expression in CSE (4 %)-activated RAW 264.7 macrophage. Additionally, In.Mcx showed marked enzyme inhibition activity against Acetylcholinesterase, Butyrylcholinesterase and Lipoxygenase. Importantly, In.Mcx dose-dependently and remarkably suppressed the CS-induced oxidative stress via not only reducing the MPO, TOS and MDA content but also improving TAC production in the lungs. Accordingly, HPLC analysis revealed the presence of many important antioxidant components. Finally, In.Mcx showed a marked decrease in the NF-κB expression both in in vivo and in vitro models. Our findings suggest that In.Mcx has positive therapeutic effects against CS-induced ALI via suppressing uncontrolled inflammatory response, oxidative stress, lipoxygenase and NF-κB p65 pathway.
