Unforeseen uses of oral contraceptive pills: Exploratory study in Jordanian community pharmacies
BackgroundThe use of oral contraceptive pills (OCPs) as a birth control method is very common worldwide. OCPs have many other labeled non-contraceptive indications, and as a result there is an associated risk of improper use, as with any other medications. This study was designed to assess the unforeseen improper uses of OCPs observed by community pharmacists in Jordan.MethodA cross-sectional study design was conducted using a self-administered survey. A convenience sample (n = 380) of Jordanian community pharmacists, were recruited through social media resources. The survey included multiple-choice and open-ended questions. Descriptive statistics and correlation analyses were completed using SPSS.ResultsMore than half of the recruited pharmacists (55.3%) were female, and the mean age of the participants was 32.58 ± 9.94. The majority of the pharmacists (85%) had good knowledge about the non-contraceptive indications of OCPs. About 53% of them confirmed their exposure to cases of the improper use of OCPs. About 67.5% of the pharmacists who confirmed exposure to such cases, reported the topical use of OCPs for the enhancement of hair growth. Around 15% of those pharmacists stated that OCPs were used to give negative results for addictive drug screening tests. In the event that the pharmacists suspected improper use, more than 90% suggested they would refrain from dispensing the pills.ConclusionThis study has spotlighted many unforeseen uses of OCPs in Jordan and highlighted the need for restricted national regulations on the monitoring of OCP prescription/selling patterns in Jordan by policymakers. Moreover, there is a need for the establishment of national educational programs for the Jordanian community regarding the safe proper use of OCPs

Knowledge and beliefs about the use/abuse of oral contraceptive pills among males: A mixed-method explanatory sequential study in community pharmacy settings
COVID-19 Treatment Guidelines: Do They Really Reflect Best Medical Practices to Manage the Pandemic?
SARS-CoV-2 (COVID-19) has been changing the world since December 2019. A comprehensive search into many COVID-19 treatment guidelines was conducted and reported in this article. This is a review paper to probe differences in COVID-19 managing strategies and explore the most common treatment plans among countries. Published guidelines from 23 countries and three references guidelines—until the end of 2020—were included in this article. The majority of COVID-19 treatment options were reported in this review and it includes antiviral drugs, antimalarial drugs, antibiotics, corticosteroids, immunotherapy, anticoagulants, and other pharmacological treatment. The presence of such information from different countries in a single comprehensive review article could help in understanding and speculation of variation in the recommended treatment in each country. This might be related to the cost of medications, the access to the medications, availability of medication that could potentially be useful in managing COVID-19 cases, and the availability/capacity of healthcare facilities. Finally, although there are various treatment groups listed in the published therapeutic guidelines worldwide, unfortunately, there is no evidence for effectiveness of most of these medications in reducing the COVID-19 mortality curve over more than one year of this global pandemic
Atmospheric pressure non-thermal plasma exposure reduces Pseudomonas aeruginosa lipopolysaccharide toxicity in vitro and in vivo
Inhaled dry powder liposomal azithromycin for treatment of chronic lower respiratory tract infection
A dry powder inhaled liposomal azithromycin formulation was developed for the treatment of chronic respiratory diseases such as cystic fibrosis and bronchiectasis. Key properties including liposome size, charge and encapsulation efficiency powder size, shape, glass transition temperature (Tg), water content and in vitro respiratory deposition were determined. Antimicrobial activity against cystic fibrosis (CF) respiratory pathogens was determined by MIC, MBC and biofilm assays. Cytotoxicity and cellular uptake studies were performed using A549 cells. The average liposome size was 105 nm, charge was 55 mV and encapsulation efficiency was 75%. The mean powder particle size d[v,50] of 4.54 µm and Mass Median Aerodynamic Diameter (MMAD) was 5.23 µm with a mean Tg of 76˚C and water content of 2.1%. These excellent physicochemical characteristics were maintained over one year. Liposomal loaded azithromycin demonstrated enhanced activity against P. aeruginosa clinical isolates grown in biofilm. The formulation was rapidly delivered into bacterial cells with >75% uptake in 1 hour. Rapid uptake into A549 cells via a cholesterol-dependent endocytosis pathway with no cytotoxic effects apparent. These data demonstrate that this formulation could offer benefits over current treatment regimens for people with chronic respiratory infection
Combining microfluidics and coaxial 3D-bioprinting for the manufacturing of diabetic wound healing dressings
Diabetic foot ulcers (DFUs) are a crucial complication of diabetes, as in a diabetic wound, each step of the physiological healing process is affected. This entails a more easily infectable wound, and delayed tissue regeneration due to the inflammation that occurs, leading to a drastic decrease in the overall patient's quality of life. As a strategy to manage DFUs, skin alternatives and wound dressings are currently receiving a lot of attention as they keep the wound environment “under control”, while providing bioactive compounds that help to manage infection and inflammation and promote tissue repair. This has been made possible thanks to the advent of emerging technologies such as 3D Bioprinting to produce skin resembling constructs or microfluidics (MFs) that allows the manufacture of nanoparticles (NPs) that act as drug carriers, in a prompt and less expensive way.In the present proof-of-concept study, the possibility of combining two novel and appealing techniques in the manufacturing of wound dressings has been demonstrated for first time. The novelty of this work consists in the combination of liposomes (LPs) encapsulating the active pharmaceutical ingredient (API) into a hydrogel that is further printed into a three-dimensional scaffold for wound dressing; to the knowledge of the authors this has never been done before.A grid-shaped scaffold has been produced through the coaxial 3D bioprinting technique which has allowed to combine, in one single filament, two different bioinks. The inner core of the filament is a nanocomposite hydrogel consisting of hydroxyethyl cellulose (HEC) and PEGylated LPs encapsulated with thyme oil (TO) manufactured via MFs for the first time. The outer shell of the filament, instead, is represented by a hybrid hydrogel composed of sodium alginate/cellulose nanocrystals (SA/CNC) and enriched with free TO. This provides a combination of two different release ratios of the API, a bulk release for the first 24 h thanks to the free TO in the shell of the filament and a sustained release for up to 10 days provided from the API inside the LPs. Confocal Microscopy verified the actual presence of the LPs inside the scaffold after printing and evaluation using the zone of inhibition test proved the antibacterial activity of the manufactured scaffolds against both Gram-positive and Gram-negative bacteria.<br/
