RESUMEN

Despite the high global prevalence, rheumatoid arthritis lacks a satisfactory treatment. Hence, the present study is undertaken to design and synthesize novel anti-inflammatory compounds. For this, quinoline and anthranilic acid, two medicinally-privileged moieties, were linked by pharmacophore hybridization, and following their computational assessments, three hybrids 5a-c were synthesized in good over all yields. The in vitro and in vivo anti-inflammatory potential of these hybrids was determined by anti-denaturation and anti-proteinase, and carrageenan-induced paw edema models. The computational studies of these hybrids revealed their drug-likeness, optimum pharmacokinetics, and less toxicity. Moreover, they demonstrated high binding affinity (-9.4 to -10.6 kcal mol-1) and suitable binding interactions for TNF-α, FLAP, and COX-II. A three-step synthetic route resulted in the hybrids 5a-c with 83-86% yield of final step. At 50 µg mL-1, the antiprotease and anti-denaturation activity of compound 5b was significantly higher than 5a and 5c. Furthermore, 5b significantly reduced the edema in the right paw of the rats that received carrageenan. The results of this study indicate the medicinal worth of the novel hybrids in treating inflammatory disorders such as rheumatoid arthritis.

RESUMEN

Suicide is the fourth leading cause of death among young people. COVID-19 pandemic has exacerbated various factors which could lead to suicidal ideation. Therefore, this study was aimed to assess self-harm and suicidal ideation among university students in Pakistan. We conducted an online, cross-sectional study among students of four major Pakistani universities. The generalized anxiety scale and patient health questionnaire were used to screen students for anxiety, depression and suicidal ideation/self-harm. Suicidal ideation/self-harm was determined from the ninth-item (score ≥1) of the patient health questionnaire. Brief-COPE was used to assess coping methods. This study included 1134 respondents (age 21.76 ± 3.48 years; female 70.5%). Around 32% students reported having thoughts of death and/or self-harm in the past 2 weeks (several days 14.8%, over half the days 7.1%, and nearly every day 10.2%). Moreover, these thoughts were equally prevalent among the demographics. Suicidal ideation/self-harm was found to be increased by the severity of generalized anxiety and depression (p < 0.001). In conclusion, the rate of suicidal ideation/self-harm is alarmingly high in Pakistani university students during the COVID-19 pandemic. There is a dire need to initiate the psychological measures to prevent suicidal behaviors in Pakistani youth. Addressing mental health disparities and preparing support systems to mitigate mental health consequences as the pandemic evolves will continue to be needed urgently.

RESUMEN

Microscopic, phytochemical and pharmacological profiles are required for correct identification of a plant material to ensure consistent efficacy and safety. But such data are not available for the leaf of an important medicinal plant, Zizyphus oxyphylla Edgew. (Family: Rhamnaceae). Therefore, the current study aimed to investigate leaves of the plant for microscopic, phytochemical and antibacterial studies. Powdered material was subjected to microscopy, proximate analyses and estimation of total primary metabolites. Then, different types of extracts prepared using various solvents in order of increasing polarity were screened for antibacterial activity against seven standard strains. The most active extract was hydrolyzed and aglycone enriched fraction was extracted and screened for antibacterial activity. The powder microscopy indicated the presence of vascular bundles filled with cuboidal calcium oxalate crystals, anisocytic stomata and xylary vessels with reticulate and scalariform thickenings. Proximate features and primary metabolites provided characteristic identifying patterns. The most active extract (methanol) upon acidic hydrolysis exhibited higher activity against B. bronchiseptica (26.01±0.01 mm), S. aureus (26.00±0.00 mm), P. aeruginosa (24.03±0.02 mm) and M. luteus (24.02± 0.00 mm). The results of the current study provide identifying microscopic and phytochemical profiles that may be useful for correct identification of leaves of the plant. Aglycone enriched extract is having remarkable antibacterial activity hence may be used for activity-guided isolation.

RESUMEN

OBJECTIVE: To investigate the prevalence and severity of lower urinary tract symptoms among calcium channel blocker users, and the impact on patients' quality of life. METHODS: The cross-sectional study was conducted at one hospital and 2 community pharmacies in Lahore, Pakistan, from November 2017 to July 2018, and comprised patients using calcium channel blockers. Data was collected using standardised scales to assess lower urinary tract symptoms and quality of life. Data was analysed using SPSS 22. RESULTS: Of the 410 subjects, 315 (76.8%) were males. The overall median age was 50.84 years, IQR 19 with 126 (30.7%) aged 41-50 years. Of the total, 108 (26.3%) patients were on calcium channel blockers alone, while the rest were taking it in combination with other drugs. Prevalence of lower urinary tract symptoms was 307 (74.9%); mild 103 (25.1%), moderate 201 (49.1%) and severe 106 (25.9%). The symptoms were significantly associated with reduced quality of life (p<0.05). CONCLUSION: Majority calcium channel blockers users had clinically significant lower urinary tract symptoms which significantly reduced patients' quality of life.

RESUMEN

OBJECTIVE: The aim of this study was to assess COVID-19-related knowledge, attitudes, and preventive practices of two Pakistani university populations. METHODS: A cross-sectional study was conducted among students and employees of two higher education institutions in Lahore, Pakistan, namely the University of Lahore and the Gulab Devi Educational Complex. Participants were recruited using a convenient sampling method. A validated 45-item, self-administered questionnaire was used to collect data. Total possible scores were 0-14 for knowledge (scores < 7, 7-10 and > 10 were considered to indicate poor, moderate and good knowledge, respectively); 0-7 for attitude (scores > 5 were considered to indicate a good attitude); and 0-18 for COVID-19 preventative practices (scores > 12 were considered to indicate good preventative practices). RESULTS: Of the 417 enrolled participants, 416 reported that they were aware of COVID-19 and social media was the major source of their information. Mean scores were 10.12 ± 2.20 for knowledge (good, moderate and poor knowledge in 50.2%, 42.8% and 7.0% of participants, respectively); 5.74 ± 1.28 for attitude (65.4% of individuals had a positive attitude); and 11.04 ± 3.34 for COVID-19 preventative practices (only 36.5% of participants had good preventive practices). CONCLUSION: Pakistani university students and employees have good knowledge and attitudes regarding COVID-19, but unsatisfactory preventive practices. Therefore, health regulators should use multiple communication approaches, such as electronic, print and social media, phone messages, etc., to increase awareness and improve practices related to COVID-19.

RESUMEN

Though, herbal medicines are prone to deterioration upon storage due to their complex nature, but less attention has been paid to investigating stability of such products to assign shelf-life. Therefore, the present study aimed to assess the accelerated stability of methanolic extract of seeds of Syzygium cumini. The extract was kept at three different storage conditions (30oC/60% RH, 40oC/75% RH and 60oC/85% RH) for a period of 6 months. The samples withdrawn at 0 (before starting the study), 1, 2, 3, 4 and 6 months were analyzed to get UV-Visible metabolomics fingerprints and determine caffeic acid contents using RP-HPLC. The comparison of metabolomics fingerprints indicated that the extract was stable for 1 month at all the three storage conditions. However, caffeic acid contents were found to be intact for a longer period of time. Following the zero order degradation, caffeic acid was predicted to be stable for more than 3 years, if kept at 25oC. The results of the present study indicate that metabolomes of methanol extract of seeds of Syzygium cumini change very fast, suggesting the development of stable formulations.

RESUMEN

The present study describes the development and validation of a simple high performance liquid chromatographic method for the determination of a novel drug candidate, 5-[(4-chlorophenoxy) methyl]-1, 3, 4-oxadiazole-2-thiol. The stability-indicating capacity of the method was evaluated by subjecting the compound's solution to hydrolytic, oxidative, photolytic, transition metal- and thermal- stress. The chromatographic separation was achieved over a C18 column (Promosil, 5 µm, 4.60 × 250 mm), maintained at 25°C, using an isocratic mobile phase comprising a mixture of acetonitrile and acidified water of pH 2.67 (1:1, v/v), at a flow rate of 1.00 mL/min and detection using a fluorescent light detector (excitation at 250 nm and emission at 410 nm). The Beer's law was followed over the concentration range 2.50-50.00 µg/ml. The recovery (98.56-100.19%, SD <5%), intraday accuracy and precision (97.31-100.81%, RSD <5%), inter-day accuracy and precision (97.50-100.75%, RSD <5%) and intermediate accuracy and precision (98.10-99.91%, RSD <5%) indicated that the method was reliable, repeatable, reproducible and rugged. The resolution and selectivity factors of the compound's peak from the nearest resolving peak, particularly in case of dry heat and copper metal stress, were found to be greater than 2 and 1, respectively, which indicated specificity and selectivity. The compound was extensively decomposed in alkaline-hydrolytic, oxidative, metal- and dry heat- stress. However, the compound in acidic and neutral conditions was resistant to photolysis. The results of the present study indicate that the developed method is specific, selective, sensitive and suitable, hence, may be used for quality control, stability testing and preformulation studies.

RESUMEN

CONTEXT: Kanji, a liquid preparation of roots of Daucus carota L. ssp. sativus (Hoffm.) Arcang. var. vavilovii Mazk. (Apiaceae), may inhibit glutathione sulfotransferase (GST) activity due to ferulic acid content. OBJECTIVES: GST inhibition activity and characterization of Kanji and methanol extract of D. carota roots, and oral absorption pattern of ferulic acid from Kanji in rats. MATERIALS AND METHODS: GST inhibition activity of Kanji and methanol extract of D. carota roots in concentration range 0.001-100.00 mg/mL was determined using Sprague Dawley rat liver cytosolic fraction. Methanol extract upon column chromatography gave ferulic acid, which was used to characterize Kanji and determine its oral absorption pattern in Wistar rats. RESULTS: The GST inhibition activity of Kanji (100.00 µg/mL), methanol extract of D. carota roots (100.00 µg/mL) and tannic acid (10.00 µg/mL, positive control) was found to be 0.162 ± 0.016, 0.106 ± 0.013 and 0.073 ± 0.004 µM/min/mg, respectively. Different Kanji samples and methanol extract contained ferulic acid (0.222-0.316 mg/g) and 0.77 mg/g, respectively. Ferulic acid did not appear in plasma after oral administration of Kanji. DISCUSSION: Kanji having solid contents 80.0 µg/mL, equivalent to 0.0025 µg/mL ferulic acid, does not inhibit the activity of GST. The oral administration of Kanji, in human equivalent dose (528 mg/kg, 16.67 µg ferulic acid), to rats indicated poor absorption of ferulic acid. CONCLUSION: Kanji having solid contents 14-36 mg/mL does not inhibit GST activity, hence may not interfere with drugs that are the substrates of GST, if taken concomitantly.

RESUMEN

The absence of chromophore and/or conjugated system, prerequisite for UV and florescent light detection, or absorbance at very low wavelength necessitates the development of simple and reliable methods for the determination of amikacin sulphate. Therefore, the present study describes for the first time dynamics of the drug derivatization using ninhydrin reagent and development and validation of a simple RP-HPLC method, using diode array detector (DAD). The variables such as heating time, heating type, drug-reagent ratio, reagent composition and storage temperature of the derivative were optimized. The analyte and aqueous ninhydrin solution upon heating for 2.00-5.00 min produced the colored drug-derivative which was stable for one month at refrigeration. The derivatized drug (20.00µL) was eluted through a column - Eclipse DB-C18 (5.00 µm, 4.60×150.00 mm), maintained at 25°C- using isocratic mobile phase comprising water and acetonitrile (70:30, v/v) at a flow rate of 1.00 mL/min, and detected at 400 nm. The method was found to be reliable (98.08-100.72% recovery), repeatable (98.02-100.72% intraday accuracy) and reproducible (98.47-101.27% inter day accuracy) with relative standard deviation less than 5%. The results of the present study indicate that the method is easy to perform, specific and sensitive, and suitable to be used for the determination of amikacin sulphate in bulk and pharmaceutical preparations using less expensive/laborious derivatization.

RESUMEN

Homemade medicinal remedies used to treat both acute and chronic ailments for centuries need to be transformed into modern evidence-based dosage forms. Therefore, the present study aimed to develop buccal dispersible film, syrup and effervescent granules of an extemporaneous antigout homemade remedy. The dosage forms were prepared using holistic remedy (HR) as an active entity and excipients masking disagreeable features. The dosage forms and HR were subjected to physicochemical evaluation, and standardised by a reversed-phase HPLC method using chlorogenic acid, caffeic acid, vanillin, and ferulic acid as analytical standards. The standardised dosage forms were investigated for antigout activity using an appropriate model. The dosage forms were found to be physically elegant and phytochemically aligned with HR. The developed dosage forms contained the selected markers and possessed antigout activity. Hence, these standardised and evidence-based dosage forms may have wider acceptance in the market compared to HR.

RESUMEN

Vaccine hesitancy (VH) is not a new phenomenon in Pakistan and is regarded as one of the primary causes of unsatisfactory vaccination campaigns. This study determined post-vaccination COVID-19 VH, factors influencing COVID-19 vaccine uptake, and public's intent to receive booster vaccinations. A cross-sectional study was conducted among adult population of Lahore, Pakistan. Participants were recruited via convenience sampling between March and May 2022. SPSS version 22 was used for the data analysis. A total of 650 participants were included in the study (age = 28.1 ± 9.7 years; male-to-female ratio nearly 1: 1). The majority of participants received Sinopharm followed by Sinovac vaccine. The top three reasons of vaccine uptake were "only vaccinated individuals are allowed at the workplace, and educational institutes" (Relative importance index (RII) = 0.749), "only vaccinated people are allowed to go to markets, malls and other public places" (RII = 0.746), and "protect myself from the infection" (RII = 0.742). The mean COVID-19 VH score was 24.5 ± 6.2 (95% CI 23.9-24.9), with not being pro-vaccines and poor economic status were the significant predictors of COVID-19 vaccine hesitancy among immunized individuals (p < .05). Acceptance of booster vaccines was negatively associated with younger age and a lower level of education. Furthermore, being pro-vaccine was associated with a greater likelihood of accepting booster vaccines (p = .001). The Pakistani public continues to express VH toward COVID-19 vaccines. Therefore, aggressive measures must be taken to combat the community factors that contribute to it.

RESUMEN

BACKGROUND: Lower respiratory tract infection (LRTI) is one of the triggering factors toward death in children below the age of five years necessitating appropriate antibiotic selection. This study aimed to evaluate antibiotic use among hospitalized children (≤5 years age) with LRTIs. METHODS: A retrospective study was conducted in seven health facilities of the central region of Punjab province of Pakistan. The medical records of hospitalized children ≤5 years diagnosed with LRTI were thoroughly evaluated to get information on demographics, clinical characteristics, and details of prescribed antibiotics. The appropriateness of antibiotics was assessed according to guidelines of the British National Formulary due to a lack of indigenous standard treatment guidelines. RESULTS: The medical records of 5926 children were searched with the majority (70.9%) diagnosed with community-acquired pneumonia (CAP) followed by acute bronchitis (14.1%). Ceftriaxone plus ampicillin and ceftriaxone plus ampicillin plus amikacin were prescribed to 39% and 11.7% study population, respectively. One-fourth of children were prescribed the wrong dose, and more than half were encountered with the incorrect route of antibiotic administration. Alarmingly, 90.2% of antibiotic prescriptions were inappropriate in our findings. CONCLUSIONS: Current surveillance study revealed a worrying degree of antibiotic misuse among hospitalized LRTI children aged ≤5 years.

RESUMEN

BACKGROUND: A death of a nine months old child in Pakistan following the rapid administration of potassium chloride raised serious concerns on the awareness of appropriate use of high alert medications (HAMs) among healthcare professionals (HCPs). This study aimed to ascertain HAMs-related knowledge among hospital pharmacists in Pakistan. METHODOLOGY: A cross-sectional study using exponential non-discriminative snowball sampling was conducted among hospital pharmacists in healthcare settings in Punjab, Pakistan. A validated study tool was used to determine knowledge on administration, regulation, and practices related to the HAMs. Barriers to conducting HAMs training in the hospitals were assessed from an open-ended question. All quantitative data were analyzed using SPSS 22.0 while the content analysis was performed on the qualitative data. RESULTS: A total of 202 hospital pharmacists were included in the study. The mean knowledge score for HAMs administration and regulation were 5.86 ± 1.89 (95% CI 5.60-6.12) and 7.25 ± 1.70 (95% CI 7.02-7.49), respectively. Approximately half of the respondents (49.5%) achieved scores ≥ 70%, demonstrating sufficient knowledge of HAMs. In the multivariable-adjusted model, increasing age and work experience were found to be the positive predictors of good HAMs knowledge. The mean practice score was 36.42 ± 1.97 (95% CI 34.05-38.77), with 62.4% of pharmacists following good HAMs-related practices. We identified several barriers to conducting HAMs training through qualitative analysis. These barriers included lack of knowledge, poor attitude and behavior of medical and paramedical staff, false beliefs, lack of active support by hospital administration, lack of cooperation between HCPs, lack of opportunities, heavy workload, insufficient human resources, financial constraints, and lack of motivation. CONCLUSIONS: A significant proportion of the hospital pharmacists had unsatisfactory knowledge and practices of HAMs. These findings underscore that training on HAMs should be conducted periodically as a part of hospital-based pharmacy education to maximize drug safety.

RESUMEN

Introduction: While many low-middle income countries (LMICs), including Pakistan, try and ensure patient safety within available resources, there are considerable concerns with medication use. Unsafe and inappropriate medication use, especially high alert medications (HAMs), is one of the important factors compromising patient safety and quality of care. Besides economic loss, HAMs contribute to greater morbidity, hospitalization, and mortality. Physicians as key members of the provision of healthcare are expected to be well aware of the administration and regulations surrounding HAMs. However, the current status is unknown in Pakistan. Consequently, the objectives of this study were to evaluate the knowledge of Pakistani physicians about the administration, regulation, and practices related to HAMs. This builds on our recently published study with nurses. Methods: An online cross-sectional study design was used, and data were gathered from the physicians throughout Pakistan using previously used self-administered questionnaires during a period of 5 months (January 1 to May 30, 2021). All data were entered and analyzed using SPSS 22 for Windows. Results: Physicians (847) who provided consent were enrolled in the study. Most physicians (62.2%) were male, aged between 25 and 30 years (75.2%) and had 2- to 5-year work experience (50.9%). About 27% were working in the emergency departments. The median (IQR) knowledge score for HAMs administration and regulation was 5 (3) and 5 (2), respectively. About 46.4% of respondents were found to have moderate knowledge about HAMs; increasing age, work experience, and higher qualifications were significantly associated (p < 0.05) with better HAMs knowledge. Around 58% had good practices relating to HAMs during their routine work. Median practice scores increased significantly (p < 0.05) with age, work experience, and postgraduate qualification. Conclusion: Most Pakistani physicians possess moderate knowledge about HAMs administration and regulations. However, their practices relating to the HAMs administration and regulations are typically sub-optimal. Consequently, HAMs awareness needs to be improved by including course content in the current curriculum, provision of hospital-based continuous training programs about patient safety and care, and establishment of multi-disciplinary health care teams, including board-certified pharmacists and specialized nurses, for the effective execution of medication use process in Pakistani hospitals in the future.

RESUMEN

High levels of stress are expected when crises affect people's lives. Therefore, this Web-based, cross-sectional study was conducted among university students from Pakistan to investigate the psychological impairment and coping strategies during the coronavirus disease 2019 (COVID-19) pandemic. Google Forms were used to disseminate the online questionnaire to assess anxiety (Generalized Anxiety Disorder-7), depression (Patient Health Questionnaire-9), and coping strategies (Brief-COPE). A total of 1134 responses (age, 21.7 ± 3.5 y) were included. The frequency of students having moderate-severe anxiety and depression (score ≥ 10) were ≈ 34% and 45%, respectively. The respondents' aged ≥ 31 y had significantly lower depression score than those ≤ 20 y (P = 0.047). Males had significantly less anxiety (6.62 ± 5.70 vs 7.84 ± 5.60; P = 0.001) and depression (8.73 ± 6.84 vs 9.71 ± 7.06; P = 0.031) scores. Those having family members, friends, or acquaintances infected with disease had significantly higher anxiety scores (8.89 ± 5.74 vs 7.09 ± 5.56; P < 0.001). Regarding coping strategies, the majority of respondents were found to have adopted religious/spiritual coping (6.45 ± 1.68) followed by acceptance (5.58 ± 1.65), self-distraction (4.97 ± 1.61), and active coping (4.81 ± 1.57). In conclusion, COVID-19 caused significant impairment on mental health of the students. The most frequent coping strategies adopted by students were religious/spiritual and acceptance coping.

RESUMEN

OBJECTIVE: The aim of this study is to ascertain the psychological impacts of coronavirus disease (COVID-19) among the Pakistani health care workers (HCWs) and their coping strategies. METHODS: This web-based, cross-sectional study was conducted among HCWs (N = 398) from Punjab Province of Pakistan. The generalized anxiety scale (GAD-7), patient health questionnaire (PHQ-9), and Brief-COPE were used to assess anxiety, depression, and coping strategies, respectively. RESULTS: The average age of respondents was 28.67 years (SD = 4.15), with the majority being medical doctors (52%). Prevalences of anxiety and depression were 21.4% and 21.9%, respectively. There was no significant difference in anxiety and depression scores among doctors, nurses, and pharmacists. Females had significantly higher anxiety (P = 0.003) and depression (P = 0.001) scores than males. Moreover, frontline HCWs had significantly higher depression scores (P = 0.010) than others. The depression, not anxiety, score was significantly higher among those who did not receive the infection prevention training (P = 0.004). The most frequently adopted coping strategies were religious coping (M = 5.98, SD = 1.73), acceptance (M = 5.59, SD = 1.55), and coping planning (M = 4.91, SD = 1.85). CONCLUSION: A considerable proportion of HCWs are having generalized anxiety and depression during the ongoing COVID-19 pandemic. Our findings call for interventions to mitigate mental health risks in HCWs.

RESUMEN

Vaccination protects people from serious illness and associated complications. Conspiracy theories and misinformation on vaccines have been rampant during the COVID-19 pandemic and are considered significant drivers of vaccine hesitancy. Since vaccine hesitancy can undermine efforts to immunize the population against COVID-19 and interferes with the vaccination rate, this study aimed to ascertain the COVID-19-vaccine-related conspiracy beliefs, vaccine hesitancy, views regarding vaccine mandates, and willingness to pay for vaccines among the general population. A web-based, cross-sectional survey was conducted (April−August 2021) among the adult population in six countries (Pakistan, Saudi Arabia, India, Malaysia, Sudan, and Egypt). Participants were recruited using an exponential, non-discriminate snowball sampling method. A validated self-completed electronic questionnaire was used for the data collection. All the participants responded to questions on various domains of the study instrument, including conspiracy beliefs, vaccine hesitancy, and willingness to pay. The responses were scored according to predefined criteria and stratified into various groups. All data were entered and analyzed using SPSS version 22. A total of 2481 responses were included in the study (Pakistan 24.1%, Saudi Arabia 19.5%, India 11.6%, Malaysia 8.1%, Sudan 19.3%, and Egypt 17.3%). There was a preponderance of participants ≤40 years old (18−25 years: 55.8%, 26−40 years: 28.5%) and females (57.1%). The average score of the COVID-19 vaccine conspiracy belief scale (C19V-CBS) was 2.30 ± 2.12 (median 2; range 0−7). Our analysis showed that 30% of the respondents were found to achieve the ideal score of zero, indicating no conspiracy belief. The mean score of the COVID-19 vaccine hesitancy scale (C19V-HS) was 25.93 ± 8.11 (range: 10−50). The majority (45.7%) had C19V-HA scores of 21−30 and nearly 28% achieved a score greater than 30, indicating a higher degree of hesitancy. There was a significant positive correlation between conspiracy beliefs and vaccine hesitancy (Spearman's rho = 0.547, p < 0.001). Half of the study population were against the vaccine mandate. Respondents in favor of governmental enforcement of COVID-19 vaccines had significantly (p < 0.001) lower scores on the C19V-CBS and C19V-HS scale. Nearly 52% reported that they would only take vaccine if it were free, and only 24% were willing to pay for COVID-19 vaccines. A high prevalence of conspiracy beliefs and vaccine hesitancy was observed in the targeted countries. Our findings highlight the dire need for aggressive measures to counter the conspiracy beliefs and factors underlying this vaccine hesitancy.

RESUMEN

BACKGROUND: COVID-19 outbreak has been accompanied by a massive infodemic, however, many vulnerable individuals such as illiterate or low-literate, older adults and rural populations have limited access to health information. In this context, these individuals are more likely to have poor knowledge, attitudes, and preventive practices related to COVID-19. The current study was aimed to investigate COVID-19's awareness of the illiterate population of Pakistan. METHODS: A cross-sectional survey was conducted among illiterate Pakistanis of ages ≥ 18 years through a convenient sampling approach. The study participants were interviewed face to face by respecting the defined precautionary measures and all data were entered and analyzed using SPSS version 22 (IBM, Armonk, NY). RESULTS: The mean age of the study participants' (N = 394) was 37.2 ± 9.60 years, with the majority being males (80.7%). All participants were aware of the COVID-19 outbreak and television news channels (75.1%) were the primary source of information. The mean knowledge score was 5.33 ± 1.88, and about 27% of participants had a good knowledge score (score ≥ 7) followed by moderate (score 4 - 6) and poor (score ≤ 3) knowledge in 41.6%, and 31.5% of respondents, respectively. The attitude score was 4.42 ± 1.22 with good (score ≥ 6), average (score 4 - 5), and poor attitude (score ≤ 3) in 19%, 66%, and 15% of the participants, respectively. The average practice-related score was 12.80 ± 3.34, with the majority of participants having inadequate practices. CONCLUSION: COVID-19 knowledge, attitude, and preventive practices of the illiterate population in Pakistan are unsatisfactory. This study highlights the gaps in specific aspects of knowledge and practice that should be addressed through awareness campaigns targeting this specific population.

RESUMEN

Adulteration is the root cause of producing not only a chemically and pharmacologically inferior but also in some instances hazardous or poisonous drug. Despite availability of several techniques, microscopy and physicochemical analyses are the most practical approaches for crude drug authentication. Hence, the present study aimed to evaluate morphological, microscopic, and physicochemical properties of root, bark, leaf, and fruit of Diospyros montana Morphological properties were determined by sensory organs, whereas microscopic features of cross-sections and powders were determined by light and scanning electron microscopy. The proximate and fluorescence analyses were performed using the standard guidelines. The physical examination of fresh, shade-dried, and powdered material showed no significant change in color. The identifying cellular structures included cuboidal cork, pitted tracheids, scalariform, reticulate and spiral xylary vessels, and rosettes, raphide, and cuboidal calcium oxalate crystals. The stomatal number, stomatal index, vein-islet and vein-termination number, and palisade ratio in the leaf were found to be 293.91 ± 32.68 mm-2 , 64.18 ± 3.42%, 22.00 ± 3.81 mm-2 and 38.40 ± 5.81 mm-2 , and 3.85 ± 0.60, respectively. Total ash, acid insoluble ash, water soluble ash and sulfated ash of leaf (9.00 ± 0.50%, 1.67 ± 0.23%, 2.00 ± 0.22% and 14.50 ± 0.99%, respectively), foaming index of bark and root (111.11 ± 2.11), and swelling index of fruit (19.00 ± 3.45) were higher than the other parts. The powder of different parts showed characteristic colors in the daylight and UV light upon treatment with various regents. The plant was found to be rich in saponins, fibers, and flavonoids. The results of the present study may serve as identifiers of different parts of Diospyros montana.
