AIMS: This systematic review aims to determine the factors associated with mosquito control among construction workers.
METHODS: Primarily, articles related to factors associated with mosquito control among construction workers were collected from two different online databases (ScienceDirect and EBSCOhost). Two independent reviewers were assigned to screen the titles and abstracts of the collected data, stored in Microsoft Excel, against the inclusion and exclusion criteria. Afterwards, the quality of the included articles was critically assessed using the Mixed Method Appraisal Tool (MMAT). Of the 171 articles identified, 4 were included in the final review.
RESULTS: Based on the thorough evaluation, mosquito-related knowledge, practical mosquito prevention measures, and Larval Source Management (LSM) were identified as vital factors associated with mosquito control among construction workers. The significant association between mosquito-related knowledge and control practices indicates higher knowledge linked to effective practices, particularly among female workers and those who were recently infected with malaria. Concurrently, there were notable challenges regarding sustainable preventive measures and larval control methods in construction settings.
CONCLUSION: Implementing effective mosquito control, including knowledge and practice on mosquito control together with vector control, is highly required to suppress the expanding mosquito population. It is recommended that employers provide continuous mosquito control education and training to their employees and reward them with incentives, while employees should comply with the guidelines set by their employers to ensure successful mosquito control and reduce the spread of mosquito-borne diseases in the construction industry.
MATERIALS AND METHODS: A MATLAB platform was used to develop software of algorithms based on image segmentation techniques to automate the calculation of patient size and SSDE. The algorithm was used to automatically estimate the individual size and SSDE of four CT dose index phantoms and 80 CT images of pediatric patients comprising head, thorax, and abdomen scans. For validation, the American Association of Physicists in Medicine (AAPM) manual methods were used to determine the patient's size and SSDE for the same subjects. The accuracy of the proposed algorithm in size and SSDE calculation was evaluated for agreement with the AAPM's estimations (manual) using Bland-Altman's agreement and Pearson's correlation coefficient. The normalized error, system bias, and limits of agreement (LOA) between methods were derived.
RESULTS: The results demonstrated good agreement and accuracy between the automated and AAPM's patient size estimations with an error rate of 1.9% and 0.27% on the patient and phantoms study, respectively. A 1% percentage difference was found between the automated and manual (AAPM) SSDE estimates. A strong degree of correlation was seen with a narrow LOA between methods for clinical study (r > 0.9771) and phantom study (r > 0.9999).
CONCLUSION: The proposed automated algorithm provides an accurate estimation of patient size and SSDE with negligible error after validation.
METHOD: A cross-sectional study was carried out through an online self-administered questionnaire from 27 September 2020 to 11 October 2020. A total of 883 people responded to the survey. The questionnaire included the participants' socio-demographic variables, attitudes, beliefs towards the COVID-19 vaccine and acceptance and rejection of vaccination, and reasons for them. Logistic regression analysis was used to analyze the predictors for vaccine acceptance and willingness to pay for the vaccine.
RESULTS: A majority (70.8%) of respondents will accept the COVID-19vaccine if available, and 66.8% showed a positive attitude towards vaccination. Monthly family income, education level, self-diagnosis of COVID-19 or a friend, family member, or colleague are significant factors influencing the acceptance of COVID-19 vaccination. The dogma of being naturally immune to COVID-19 was a key reason for the refusal of the vaccine. Less than half (48%) of those who refuse will vaccinate themselves if government officials have made it compulsory. A third (33.9%) of participants were willing to pay up to (7 USD) 1000 Pkr (Pakistani Rupees) for the vaccine.
CONCLUSION: The population's positive attitude should be improved by increasing awareness and eradicating false myths about vaccines through large-scale campaigns.
METHODS: This is a cross-sectional descriptive study from a general population of Sindh, Pakistan, with a total of four hundred and fifteen (n = 415) participants. A confirmatory factor analysis was used to verify the factor structure between Pharmaceutical services (PS), the Skill of Pharmacists, Non-pharmaceutical services (NPS), and pricing (P). Pearson correlation analysis, Kendall's tau correlation analysis, and Spearman's rho correlation analysis were used to identify the correlation between different factors, such as PS, SKP, NPS, and P.
FINDINGS: The 23-item scale that consisted of four elements have shown an acceptable root mean squared error of approximation (0.076), Cronbach's alpha (0.787), and Chi-square value (3.381) (P < 0.001). Of the respondents, 56.4% rated their satisfaction on pharmacist attitude, whereas 67.2%, 41.4%, and 51.8% were satisfied with other services, such as receipt provided on medication they take, prescription drug service and availability of pharmacies on the weekend and public holidays, respectively.
CONCLUSION: This cross-sectional study confirms that there are relationships among PS, SPK, NPS, and P. Moreover, there is a lack of facilities in community pharmacies in Sindh, such as the unavailability of a consultation room, immunization services, information on routine health matters, and medication record.
METHODS: In silico analysis was performed using molecular docking of chemical compounds with vascular endothelial growth factor (VEGF). The different computational tools used were AutoDock Vina, BIOVIA DISCOVERY studio, and PyMOL. Drug likeness and toxicity were analyzed by SWISS ADMET. Cells that were 60-70% confluent were treated with different concentrations of hydrogen peroxide (H2O2) (100-2000 μM) and ascorbic acid (30, 60, 90 μg/mL). The MTT cell proliferation assay was performed to compare the proliferative potential of HepG2 cells treated with H2O2 or ascorbic acid with untreated HepG2 cells using 96-well plates.
RESULTS: The lowest binding energy of VEGF with vitamin C -5.2 kcal/mol and L-ascorbic acid-2 glycoside -4.7 kcal/mol was observed by in silico analysis. Vitamin C was selected because it exhibited a high interaction with VEGF and fulfilled Lipinski's rule, and had better oral viability and pharmacokinetics compared to L-ascorbic acid-2 glycoside. Cell viability assays showed that vitamin C had significant apoptotic effects (P
OBJECTIVES: This study aimed to examine clinical pharmacist interventions and identify opioid medication-related issues in patients with cancer.
METHOD: We conducted a retrospective observational study at Shaukat Khanum Memorial Cancer Hospital and Research Center in Lahore, Pakistan, conducting a chart review from 1st July 2021 to 31st December 2021.
RESULTS: Out of 10,534 opioid medication orders, we documented a total of 974 interventions based on our inclusion criteria. Tramadol and morphine accounted for most of these interventions, comprising 49.27% (n = 475) and 40.04% (n = 386), respectively. Regarding clinical significance, 41.70% (n = 406) were deemed significant, while 37.36% (n = 365) were somewhat significant. The majority of interventions, i.e., 54.05% (n = 521), primarily aimed at optimizing patient outcomes, followed by a secondary aim of improvements in communication, i.e., 25.52% (n = 246).
CONCLUSION: This study establishes the evaluation of clinical pharmacist interventions on opioid medication use in patients with cancer, an issue particularly in oncology settings in Pakistan. The findings emphasize the crucial role of clinical pharmacists in addressing issues related to opioid issue medications, thus improving patient safety and optimizing opioid use for patient well-being.
METHODS: The study consisted of four phases with phase-I focusing on literature review, phase II was the actual questionnaire development phase, face and content validity was determined in phase III, and finally pilot testing was performed in phase IV to determine validity and reliability. The development phase encompassed a thorough review of literature, focus-group discussion, expert review, and evaluation. The validation phase consisted of content validity, face validity, construct validity, convergent validity, and reliability. The pilot testing was performed by studying the KAP of 100 practicing physicians in tertiary care hospitals in Pakistan. The knowledge section of the validation phase utilized Item Response Theory (IRT) analysis. The attitude and practices sections utilized Exploratory Factor Analysis (EFA) theory. The reliability analysis utilized Cronbach's alpha and correlations.
RESULTS: The CKD-KAP questionnaire had three main sections: knowledge, attitude, and practice. During the validation, IRT analysis was performed on knowledge, which focused on the measure of the coefficient of discrimination and difficulty of the items; 40 out of 41 knowledge items have both discrimination and difficulty coefficients within an acceptable range. The EFA model was also fitted in the attitude and practices section, and scree plot and Eigenvalues suggested three and four dimensions within the attitude and practices section. The factor loading of all items was found to be acceptable except for one item in attitude which was deleted. The convergent validity demonstrated a significant association between all three sections except knowledge and practices. The reliability (internal consistency) analysis demonstrated Cronbach's alpha values above 0.7 and significant inter-item correlation. The final model of CKD-KAP had 40 knowledge, 13 attitude, and 10 practice items with a combination of both positive as well as negative questions and statements.
CONCLUSIONS: The CKD-KAP was found to be psychometrically valid and reliable, hence can be used to determine the knowledge, attitude, and practices of physicians toward chronic kidney disease.
Methods: This was a questionnaire-based, cross-sectional study that included undergraduate medical students of a public sector medical university in Karachi, Pakistan. A total of 573 students participated voluntarily, of which 300 were provided a manual questionnaire and 273 filled it online. The reliability of the questionnaire was assessed using Cronbach's alpha at 0.791. The collected data were analysed using IBM SPSS Statistics for Windows, version 21.0.
Results: Out of 573 participants, 99.3% (n = 298) of students filled the questionnaire manually, whereas 100% of students filled the questionnaire online. Almost two-thirds of students used university transport; more than 90% lived more than 5 km from the university and 56% had a traveling time of more than an hour. Approximately 15.4% of students reported physical trauma and some form of harassment. Sheldon Cohen's stress scale surprisingly revealed 90% of students to be within the moderate-to-high stress category. Risk factors were associated with stress levels and significant associations were observed with noise exposure (P = 0.023) and sleep quality (P = 0.001). The most common reported stressors associated with commuting included overcrowding, long travel, and air and noise pollution. Noise pollution was the main predictor of stress among commuters.
Conclusion: Poor transportation has adverse effects on health and academic performance. Administration in their respective jurisdictions is needed to investigate this matter to make commuting a routine rather than a hassle.
Methods: A cross-sectional study including 193 patients diagnosed with appendicitis was conducted at four hospitals in Pahang, Malaysia. Those who presented between 1 February 2020 and 17 March 2020 were included in the pre-MCO group and those between 18 March 2020 and 30 April 2020 in the MCO group. The definitions of simple and complicated appendicitis were based on the Sunshine Appendicitis Grading Score. The primary outcome was the incidence of complicated appendicitis, and the secondary outcomes were length of stay, a composite of surgical morbidities and a composite of organ failure.
Results: A total of 105 patients in the pre-MCO group and 88 in the MCO group were analysed. The incidence of complicated appendicitis was 33% and it was higher in the MCO than in the pre-MCO group (44% versus 23%, P = 0.002). The MCO period was independently associated with complicated appendicitis in the logistic regression (P = 0.001). It was also associated with prolonged length of stay (3.5 days versus 2.4 days, P < 0.001) and higher overall surgical morbidity (19% versus 5%, P = 0.002).
Conclusion: The MCO imposed during the COVID-19 pandemic was associated with a higher incidence of complicated appendicitis and surgical morbidity.
