DRY POWDER INHALERS TECHNIQUE OF COMMUNITY PHARMACISTS: AN OBSERVATIONAL STUDY FROM LAHORE, PAKISTAN

Fri, 15 Nov 2024 00:00:00 +0000

Introduction: Inaccurate utilization of various inhaler devices may severely influence the drug therapeutic effectiveness. The aim of this study is to evaluate the community pharmacist knowledge, attitudes and practice regarding the use of dry powder inhalers (DPIs).

Method: The present observational study was conducted for the evaluation of pharmacist’s knowledge and patient counseling attitude concerning the use of DPIs. A total of 114 community pharmacists from various community pharmacies of Lahore, Punjab were selected and a validated questionnaire was used to assess the knowledge of community pharmacists. The DPI technique presented by “National Heart, Lung and Blood Institute” was used as criteria for evaluation. The covert simulated patient approach was used to evaluate the DPI technique of pharmacists without any biasness.

Results: Out of 114, only 27.2% pharmacists presented adequate knowledge about the correct use of inhaler device (DPIs). Pharmacists from chain pharmacies presented higher adequacy 66.7% as compared to individual pharmacies i.e., 33.3%. Pharmacists whose working experience was more than 5 years presented better DPIs technique knowledge.

Conclusion: The study demonstrated that majority of the community pharmacist (72.8%) have inadequate dry powder inhaler technique at baseline. Setup type (Chain pharmacies) and work experience were the demographic variables that were positively associated with the adequate technique.

TREATMENT OF COMMINUTED MANDIBULAR FRACTURE WITH CLOSED REDUCTION AND MANDIBULAR FIXATION VERSUS OPEN REDUCTION AND INTERNAL FIXATION

Fri, 15 Nov 2024 00:00:00 +0000

Background and aims: Injuries from firearms remain a serious public health concern, contributing significantly to our society's morbidity, mortality, and costs. Securing an airway, controlling bleeding, determining other injuries, and conclusively repairing the traumatic facial abnormalities are the four primary phases in the care of patients with gunshot wounds to the face. This study aimed to compare the effects of two treatment approaches for mandibular gunshot injuries: closed reduction and maxillomandibular fixation (MMF) against open reduction and internal fixation.

Methods: Between 2020 and 2023, mandibular fractures were found in two equal groups at the Military Hospital in Sana'a, Yemen, where the Department of Oral and Maxillofacial Surgery conducted the study. Twenty patients in group A received treatment by closed reduction and maxillo-mandibular fixation, and another twenty patients in group B received treatment by open reduction and internal fixation. Then complications following surgery were studied. Every patient had made a follow-up call between the second and eighth weeks; following the surgery, both groups' cases of postoperative infection, malocclusion, non-union or malunion of fracture fragments, facial asymmetry, exposed plates, and bone resorption were recorded and assessed radiographically and clinically.

Results: The study analyzed patients with mandible fractures, focusing on G.S.I. and bomb explosions. Most injuries occurred in the body, with parasymphsis being the most common site. Bone exposure was prevalent in 95% of patients. After a two-week follow-up, the ORIF treatment method was associated with more post-operative complications than the CR-MMF treatment method. Wound contraction was more common in the ORIF group (22.5%), followed by bone loss (15%). Plate exposure, nonunion, and malunion were more prevalent in the ORIF group.

Conclusions: In comparison to open reduction with internal fixation, it was determined that closed reduction is the most efficient and dependable management strategy for treating comminuted fractures of the mandible brought on by gunshot injuries. It also has a lower rate of complications.

COMPARATIVE OF PIEZOELECTRIC AND CONVENTIONAL OSTEOTOMY FOR LOWER THIRD MOLAR IMPACTION EXTRACTION WITH SUBMUCOSAL DEXAMETHASONE INJECTION

Fri, 15 Nov 2024 00:00:00 +0000

Background and aim: The most common procedure performed in the outpatient setting in maxillofacial surgery practices is the extraction of impacted third molars. This technique often requires incision, flap reflection, and bone removal, which causes tissue stress and involves large amounts of connective tissue and blood vessels in the third molar area. The aim of this study was to examine decompression surgery and the rotary technique alone and to evaluate the combined effect of decompression surgery and conventional osteotomy with submucosal dexamethasone injection on the sequelae after surgical extraction of impacted mandibular third molars.

Methodology: With a sample of sixty individuals, a randomized controlled clinical trial was carried out. Four groups of fifteen participants each were created: Group 1 was for conventional rotatory therapy; Group 2 was for conventional rotatory therapy plus a 4 mg dose of dexamethasone following surgery; Group 3 was for piezosurgery; and Group 4 was for piezosurgery plus a 4 mg dose of dexamethasone following surgery. The surgical working time was determined in minutes, the maximum mouth opening was measured in millimeters at baseline and on the second, fifth, and seventh day using a Vernier Caliper, and the postoperative pain was quantified using a Visual Analog Scale (VAS) every day for the first week.

Result: A study involving 36 women and 24 men aged 21-32 years performed a procedure involving impacted lower third molars, with a 100% success rate. All patients showed soft tissue healing without serious events or infection. Pain levels were greater in group 3 (3.7 degrees) and lower in group 2 (2.6 degrees). No significant differences were found in pain levels of dexamethasone injection among the four groups.

Conclusion: The use of submucosal dexamethasone injection with conventional and electrosurgical osteotomy is beneficial for alleviating post operative complication after removal of impacted third molar surgery.

AMELOBLASTOMA IN POPULATION OF YEMEN: ANALYZING THE PREVALENCE AND CLINIC PATHOLOGIC FEATURES OF AMELOBLASTOMA IN A YEMENI POPULATION

Fri, 15 Nov 2024 00:00:00 +0000

Background and aims: Ameloblastoma is an uncommon tumor of odontogenic epithelium (ameloblasts, or the outer part of the teeth during development) that can be benign or malignant. It usually appears in the lower jaw rather than the upper jaw. The initial ameloblastoma is often treated with radical tumor resection. Analyzing the prevalence and clinic pathologic features of ameloblastoma in a Yemeni population was the goal.

Material and Methods: This retrospective cross-sectional study was carried out in all patients who were diagnosed with oral tumors at the targeted centers in Sana’a city (Al-Mamoon Center, Central Laboratory, and Al-Awlqy Laboratory Centers) in the period June 2020 to June 2022. This study is based on data taken from patients’s files that include age, gender, location, and histopathology. The study used descriptive statistics and SPSS version 26 for data analysis, describing quantitative non-parametric data using median and parametric data using mean and standard deviation.

Results: The ameloblastoma tumor prevalence was 8.8% of all oral tumors (330 cases). The mean age of the ameloblastoma patients was 31.10±11.4 (± SD) years and ranged from 11 to 80 years, with 1:1.2 males to females. The majority of ameloblastoma cases occurred in the lower jaw (93.1%; N=27), and the posterior part of the lower jaw was the main site for ameloblastoma tumors (79.3%; N=23), and 86.2%; N=23 of ameloblastoma was epithelial origin and 13.8%; N=4 was variegated origin. In terms of histological type, 65.5%; N=19 of the cases were not diagnosed, and the remaining cases showed a rate of 24.1%; N=7 for a multicystic tumor and 10.3%; N=3 for a unicystic tumor. 96.6%; N=28 of ameloblastoma cases were benign tumors, and only 3.4%; N=1 case was a malignant tumor.

Conclusions: The prevalence of ameloblastoma was significant, and these findings increase the awareness level of determent type of lesion for better diagnosis, management, and preventing measures.

STUDY OF SOME FLUOREN-9-ONE THIOSEMICARBAZONES: SYNTHESIS, CATALYTIC EFFECTS AND SPECTRAL CHARACTERIZATION

Fri, 15 Nov 2024 00:00:00 +0000

Aim and objective: Nowadays, Schiff bases have shown a remarkable importance in medicinal chemistry research. Semicarbazones, thiosemicarbazones and their derivatives are important Schiff base ligands with biological properties. Fluorenones are important organic compounds used in many different fields. Here, we reported the synthesis of fluoren-9-one thiosemicarbazones (F1-F4).

Methods: For their synthesis, we first carried out a theoretical study based on the physical properties (reasonable pharmacokinetics and drug availability) of the compounds using Lipinski's rules. We also varied the reaction conditions using several reagents (HCl, 1N; H₂SO₄ conc. and GAA) and ethanol in order to optimize reaction yields. Structure of each molecule was characterized by spectrometrical analysis (MS and IR, and especially NMR ¹H and ¹³C).

Results: During the course of the study, we observed an increase in reaction yields in the presence of the less aqueous acids, particularly with GAA, which gave the best yields (89, 77, 91 and 96%) for molecules F1, F2, F3 and F4 respectively.

Conclusion: We noted that compounds presented essential properties to exhibit pharmaceutical activities. They could have a variety of pharmaceutical activities on pathogens resistant to existing treatments.

THE ATTITUDE OF PARENTS REGARDING THEIR CHILD IMMUNIZATION IN LAHORE, PAKISTAN

Fri, 15 Nov 2024 00:00:00 +0000

Background: Many parents harbor negative views about vaccine-preventable diseases (VPD) and hold misunderstandings about the ingredients, side effects, and efficacy of vaccines. The resurgence of diseases preventable by vaccines was believed to be primarily due to insufficient childhood vaccination practices. The study aimed to assess parental attitude towards their children's vaccinations.

Methods: The present study is a multi-centered, cross sectional observational study to evaluate the attitude of the parents regarding their child immunization in Lahore, Pakistan. Quantitative research methodology involving validated questionnaires and research tools were utilized in order to evaluate the attitude of the parents regarding their child immunization. A total of 353 parents belonging to urban and rural areas of Lahore having children of different ages were recruited for the present study.

Results: Out of 353 parents surveyed, majority of the study subject were mothers (56.1%) with age 25-29 years (30%). Majority of the parents (70.3%) were observed to have negative attitude while only 29.7% of the respondents presented positive attitude at baseline. It is observed that the occupation, no of children, residency, living class and health care providers in respondent family shows highly significant statistical association (p<0.001) with patient attitude regarding their child immunization.

Conclusions: The present study concludes that the parents showing negative attitude do not get their children vaccinated. They feel that it is a formality and they find it hectic to take their children to vaccination centers for immunizations. The immunization status was also significantly influenced by sociodemographic factors. In order to achieve positive attitude, efforts should be made to tell them benefits of vaccination and by changing their thinking about side effects of vaccine by educating them about the beneficial effects of vaccines and its safety.

MOLECULAR MODELLING AND VIRTUAL SCREENING APPLICATION TO THE COMPUTER-AIDED DESIGN OF ANTICANCER INHIBITORS WITH A FAVORABLE PHARMACOKINETIC PROFILE AGAINST E6 PAPILLOMAVIRUS TYPE 16

Fri, 15 Nov 2024 00:00:00 +0000

Background: Worldwide, cervical cancer (CC) is the fourth most common women cancer. It is crucial to develop more effective treatments for this disease. We aim at designing new anticancer compounds with a favorable pharmacokinetic profile, targeting the E6 oncoprotein of human papillomavirus type 16 (HPV16 E6).

Methods: Computer-Aided Molecular Design (CAMD) has been carried out by the elaboration of a Quantitative Structure-Activity Relationship (QSAR) model of molecular complexation, through the correlation between the relative Gibbs free energy (rGFE) and the observed biological activities of a series of flavonoids inhibitors separated in training (TS) and validation sets (VS). Starting from the 3D crystallographic structure of the oncoprotein HPV16 E6 (Protein Data Banck (PDB) input code: 4GIZ), enzyme – inhibitor complexes were built by in situ modification of the native ligand (FLAV1, IC₅₀^exp= 850 nM), replacing substitution R-groups at nine different positions R₁ – R₉.

Results: The complexation QSAR model equation (pIC₅₀^exp=-0.5494 × DDG_com+5.9983 (1); n=16; R²=0.98) explains 98% of the variation in biological activity by that of rGFE of the analogues used. The subsequent 3D pharmacophore model (PH4) generated from the active conformations of FLAVS (pIC₅₀^exp= 1.0177× pIC₅₀^pre– 0.0927(2); n=16; R²=0.90) was used as a virtual selection tool to identify new analogues from a virtual library (VL) reaching two digits nanomolar range predicted activity.

Conclusions: The combination of molecular modelling and in silico screening of VL using the PH4 pharmacophore has led to the discovery of new promising anticancer candidates, with favorable pharmacokinetic profiles against HPV16 E6. Among them, the top two predicted respective inhibitory powers IC₅₀^pre (50 nM and 61 nM).

MODULATION OF MITOCHONDRIAL MEDIATED APOPTOSIS BY SOLVENT FRACTIONS OF THE FRUIT EXTRACTS OF SARCOCEPHALUS LATIFOLIUS (SMITH) BRUCE

Joan Uchechukwu Imah-Harry, Olufunso Olabode Olorunsogo — Fri, 15 Nov 2024 00:00:00 +0000

Aim and Objective: However, this claim has not been scientifically substantiated. In this study, we investigated the inductive effect of the crude methanol extract (CMESL) and a chloroform subfraction (sCFSL) of Sarcocephalus latifolius fruits on mPT, in vivo.

Methods: Thirty-five male wistar rats (90±10 g) were acclimatized, divided into seven groups, and treated with 1% DMSO (control) and 25, 50, and 100 mg/kgbw of each of the fractions for thirty days. Rats were sacrificed and liver mitochondria were isolated by differential centrifugation. The MOMP, DNA fragmentation, p53, Bax and BCl-2 protein expressions, Cytochrome C release, and caspase – 3 and -9 activities were assayed in liver tissue by standard methods.

Results: CMESL and sCFSL induced mPT pore. The sCFSL induced MOMP maximally at 100 mg/kgbw, inhibited LPO (78%), enhanced mitochondrial ATPase activity (27.96±0.04 µmole/mg Protein/min) than CMESL (17.58± 0.03 µmole/mg Protein/min) at the same dose. Similarly, sCFSL caused DNA fragmentation; (77.33%), enhanced caspases -3 and -9 activation; increased p53 and Bax expression levels, increased Cytochrome C release, and downregulated BCl-2 protein expression, compared to CMESL.

Conclusion: These findings showed that sCFSL contains bioactive agents that can induce mitochondrial-mediated apoptosis, and therefore a potential target to be explored in the management of tumors and cancer.

DEVELOPMENT, SCREENING AND OPTIMIZATION OF ROSUVASTATIN LOADED NANOSTRUCTURED LIPID CARRIERS FOR IMPROVED THERAPEUTIC EFFICACY

El Sayed Gamal E. Shaheen, Walid Anwar, Sherif K. Abu-Elyazid, Mohsen I. Afouna — Fri, 15 Nov 2024 00:00:00 +0000

Objective: The aim of the current study was to be screening of the formulation components, prepare ROS-NLCs by hot homogenization–ultrasonication technique and optimized by Full factorial design then formulations prepared were further characterized.

Methods: The screening experiments were carried out to select the most suitable solid lipids, liquid lipids, and surfactants. Moreover, physical compatibility between the solid lipids and liquid lipids, along with their proportions, was evaluated. Additionally, characterization and optimization of the developed formulations were outlined and identified. Primarily, the solubility of ROS-Ca in various solid lipids and liquid lipids is the key factor for choosing the optimal one.

Results: Stearic acid, Glyceryl Monostearate (GMS), and Compritol®888 ATO exhibited a higher ability to solubilize ROS-Ca, with solid lipid values per 10 mg of ROS-Ca (w/w) recorded as 750±3.56 mg, 1250±4.36 mg, and 1750±5.16 mg, respectively. In the systematic screening of different liquid lipids, Transcutol® HP (98.41 mg/ml), CapryolTM90 (78.64 mg/ml), and Labrafac MC60 (64.36 mg/ml) demonstrated a good affinity for the drug. The (Stearic acid-Transcutol® HP) mixture showed phase separation with oil droplet residue on filter paper, whereas the (GMS-Transcutol® HP) mixture showed no separation and left no oil droplet residue on filter paper. The optimized NLC formulations composed of glyceryl monostearate GMS (solid lipid) and Transcutol® HP (liquid lipid) as lipid phase, poloxamer 188 and Tween 80 (1:1 ratio) as surfactants.

Conclusions: Study concludes the ability of NLCs to improve the oral bioavailability of poorly water-soluble drugs by enhancing solubilization and dissolution rates in the gastrointestinal tract is well-recognized.

VIRTUAL DESIGN OF NOVEL OF ORALLY BIOAVAILABLE PIPERAZINE INHIBITORS OF ENOYL-ACYL CARRIER PROTEIN REDUCTASE OF MYCOBACTERIUM TUBERCULOSIS WITH FAVORABLE PHARMACOKINETIC PROFILES

Fri, 15 Nov 2024 00:00:00 +0000

Background: Drug-resistant strains have been a real problem for anti-tuberculosis therapies in recent decades. Here we elaborated the virtual rational design and evaluation of a novel class of piperazine (PPZ) analogs as InhA-Mt inhibitors with a favorable pharmacokinetic profile.

Method: By in situ modification of the crystal structure of InhA-PPZ1 (Protein Data Bank (PDB) entry code: 1P44), which is the reference structure of a test set of 12 PPZs with their known inhibitory potencies experimental data (IC₅₀^exp), we prepared three-dimensional (3D) models of Inha-PPZx complexes. A structure activity relationship (SQR) model was built in the gas phase in the search for active conformations of PPZ 1-12 linearly correlating the calculated enthalpy of formation of the InhA-PPZ complex and thepIC₅₀^exp. Finally Lipinski's rule of 5 was used to filter the VCL which was subsequently screened by the pharmacophore model. The predicted activities of the new PPZ analogs obtained were evaluated with the initial QSAR and their pharmacokinetic profile was also evaluated.

Results: The virtual combinatorial library of more than 310,550 PPZ analogs was filtered by Lipinski's rule until it reached 19,044 analogs. Virtual screening by the pharmacophore made it possible to select 50 potential new analogues with predicted inhibitory potencies up to 100 times better than that of PPZ1 (IC₅₀^exp=160 nM). The predicted pharmacokinetic properties of the new analogues showed high cell membrane permeability, side effects and high human oral absorption compared to current anti-TB candidates.

Conclusions: The combined use of molecular modeling and PH4 in virtual screening makes it possible to propose new powerful anti-tuberculosis drugs with favorable pharmacokinetic profiles.

DEVELOPMENT, CHARACTERIZATION, AND OPTIMIZATION OF REPAGLINIDE LOADED SPANLASTICS ALONG WITH INVESTIGATION OF DRUG SOLUBILITY IN VARIOUS MEDIA

Hesham Seary, Elsaied H. Barakat, Mohamed A. Raslan, Ahmed M. Samy — Fri, 15 Nov 2024 00:00:00 +0000

Objective: This study seeks to explore the solubility of an antidiabetic drug with poor water solubility, Repaglinide (RPG), in various media, and develop and optimize RPG-loaded spanlastic formulations.

Methods: A 72-hours solubility study was conducted for RPG in different media, followed by UV spectrum analysis. Spanlastics containing RPG were prepared through the thin-film hydration (TFH) method combined with ultrasonication, incorporating varying concentrations ofthe lipophilic, non-ionic surfactant agents, Span 60 and Tween 80. Characterization was performed To assess particle size (PS), polydispersity index (PDI), zeta potential (ZP), and entrapment efficiency (EE%). Optimization was achieved by analysing characterization results and using a mixture design of Design Expert software which predicted the optimized formula.

Results: RPG exhibited the highest solubility in phosphate buffer saline (PBS, pH 6.8) incorporating 0.5% Tween 20 (168.595 µg/mL), followed by PBS with 0.1% Tween 80 (80.355 µg/mL), PBS alone (56.163 µg/mL), and PBS with 0.1% sodium lauryl sulphate (SLS) (53.706 µg/mL). UV scanning in methanol revealed three characteristic absorption bands for RPG, with peak selection optimized for molar absorptivity in each medium. The RPG-loaded spanlastic formulations demonstrated nano-sized vesicles with uniform size distribution, high stability, and efficient drug encapsulation. Optimized spanlastics predicted a particle size 126.162 nm, PDI 0.416, ZP-43.258 mV, and EE% 77.753%.

Conclusions: This research emphasizes the potential of optimized RPG-loaded spanlastics, developed through the thin-film hydration method, as a promising approach for improving the solubility and stability of poorly water-soluble drugs. RPG showed the highest solubility in PBS (pH 6.8) containing 0.5% Tween 20, and the formulation achieved desirable nanosize, uniformity, and high encapsulation efficiency.

Assoc. Prof. Ahmad Najib — Fri, 15 Nov 2024 00:00:00 +0000

The Universal Journal of Pharmaceutical Research is a commendable reflection of the journal’s commitment to impactful global health research. The featured studies on innovative antileishmanial and anti-inflammatory therapies highlight the strides being made in disease treatment, while studies on medication adherence in some countries demonstrate a thoughtful approach to improving healthcare accessibility in diverse contexts.

In this welcome, I will discuss the importance of presenting the author's facial image in the journal to help global readers and research colleagues recognize them. Facial expressions play a crucial role in both conscious and unconscious emotional communication, with frowns indicating rejection and smiles suggesting happiness. The ability to interpret these expressions is foundational for empathy and understanding others' reactions. Individual facial features contribute to emotional expression, and psychologists argue that a face is perceived holistically rather than as a collection of parts. Research indicates that certain brain regions respond more actively to faces, with differences noted between shy and sociable individuals in their brain activity when viewing unfamiliar faces. Additionally, attractive faces activate a widespread neural network related to perception, decision-making, and reward.

THE CURRENT TRENDS OF PSORIASIS TREATMENT IN DERMATOLOGICAL PRACTICE

Mutaia Abuarij, Ali Alyahawi, Ali Alkaf — Fri, 15 Nov 2024 00:00:00 +0000

Psoriasis is associated with many complications. The severity of the disease can range from mild or moderate to severe. Treatment for this condition should be long-term and multifaceted, and may change over time based on the condition severity. Treatment for patients with psoriasis often includes treatment of the underlying pathophysiology. Other treatments for psoriasis include topical medications, phototherapy, and medications (nonspecific/biologic and biologic). Pharmacologic therapy is generally guided by disease severity and impact on patient quality of life, ranging from topical medications to phototherapy and, when necessary, systemic medications. However, challenges remain, including side effects, poor treatment, high costs, and variability in individual responses. Recent biologics have proven effective in psoriasis; on the other hand, there are differences among these drugs such as mechanisms of action, duration of response, and side effects. Biologics are often used to treat moderate to severe psoriasis and can be the treatment of choice, particularly in patients with comorbidities such as psoriatic arthritis or in whom psoriasis treatments such as methotrexate or cyclosporine are contraindicated. Different types of therapy are often used in combination. Combined therapies may improve treatment. Clinical guidelines classify psoriasis as mild or mild to severe, with mild lesions managed locally and moderate to severe lesions managed systemically.

Fri, 15 Nov 2024 00:00:00 +0000

Nanogels have become significant in biomedical science research due to various unique characteristics. Hydrogels are three-dimensional crosslinked polymer networks that swell by absorbing aqueous solvents. These polymeric networks with sizes from nanometers to micrometres incorporate features of both hydrogels and nanoparticles, exhibiting high efficiency in drug delivery, tissue engineering, and biosensing. The synthesis process involves the chemical and physical crosslinking process, and the nanoparticles can be incorporated either during gelation or in situ. The resulting hydrogel nanoparticle composites exhibit high drug encapsulation capacity, adjustable swelling behaviour, biocompatibility, and responsiveness to stimuli like pH, temperature, and enzymes. They are of uniform size and less toxic, ideal for controlled and targeted drug delivery, and improved therapeutic effectiveness. Newer developments have highlighted its applications in cancer therapy, cardiovascular treatment, wound healing, and neurodegenerative disease management. This review provides a comprehensive analysis of the types of nanogel, the development process and wide-ranging applications, along with insights into future developments in this promising field.
