BACKGROUND: Cosmos caudatus Kunth is a medicinal herb used traditionally in Latin America and South East Asia to retard aging, rigidify bones and for several cardiovascular uses.
OBJECTIVE: Is to assess C. caudatus extract/fractions' antioxidant and vascular smooth muscle cells (VSMC) migration and invasion inhibition capacity in vitro.
METHODS: Cosmos caudatus shoots were extracted by cold maceration in 50% ethanol to produce crude (CEE), and then the extract was fractionated to butanol (Bu.F), and aqueous fractions (Aq.f). Phenolics and saponins were quantified in extract and fractions by colorimetric methods and their antioxidant capacity was assayed in four different tests. Cytotoxic effect and safety level concentrations were determined for the fractions by using MTT assay. Migration and invasion inhibitory potential were measured in vitro at three different concentrations equivalent to (IC10, IC25, and IC50). Finally, invasion inhibitory index was calculated to obtain the best fraction(s) that show(s) the highest ratio of cell invasion inhibition to the total cell migration inhibition.
RESULTS: Butanol fraction yield was the lowest; nevertheless, its phytochemical contents, antioxidant activities as well as its potency were the highest. Unlike other fractions, Bu.F was strongly correlated with all antioxidant assays experimented. In addition, it has the highest inhibitory effect at IC25 against VSMCs migration and invasion that accounts for 53.93% and 59.94% respectively. Unexpectedly, Bu.F and CEE at IC10 displayed the highest invasion inhibitory index (approx. 68%).
CONCLUSION: Butanol fraction of C. caudatus offers a potentiality for the discovery of new leads for preventing atherosclerosis.
Methods: A cross-sectional study, using a validated 23-item self-administered questionnaire, was conducted among pharmacists from 11 public hospitals in the State of Selangor, Malaysia, from December 2016 to January 2017. All public hospital pharmacists (n=432) were invited to participate in the survey. A 5-point Likert scale was employed in the questionnaire; the perception section was scored from 1 (strongly disagree) to 5 (strongly agree) while the practice section was scored from 1 (never) to 5 (always). Both descriptive and inferential statistical analyses were used to analyse data.
Results: Of the 432 pharmacists surveyed, 199 responded, giving a response rate of 46.0%. The majority of the respondents agreed (n=190, 95.5%) that the AMS programme improves patient care at their hospitals (median=5; IQR=1). Slightly less than half of the respondents indicated that a local antibiotic guideline was established in their hospitals (median=3, IQR=2.5), and had taken part in antimicrobial awareness campaigns to promote optimal use of antimicrobials in hospitals (median=3, IQR=1).
Conclusions: Overall, the perception and practices of the surveyed hospital pharmacists towards AMS programme were positive. National antibiotic guidelines, which take into consideration local antimicrobial resistance patterns, should be used fully to improve antimicrobial usage and to reduce practice variation. Collaboration among healthcare professionals should be strengthened to minimise the unfavourable consequences of unintended use of antimicrobial agents while optimising clinical outcomes.
METHODS: A rapid online survey comprising 22 items was administered during the rapid outbreak of COVID-19 in Pakistan. Questions were focused on the prevention, transmission, clinical features, and control of COVID-19. In addition, the attitudes and practices of the participants were explored. Descriptive statistics, Mann-Whitney tests, Kruskal-Wallis tests, and regression analysis were carried out during data analysis.
RESULTS: A total of 1257 respondents participated in this study. Most of the respondents had good knowledge (good = 64.8%, average = 30.5%, poor = 4.7%) of COVID-19. Gender, marital status, education, and residence were observed to have a significant association with the knowledge score. A vast majority of the survey respondents (77.0%) believed that COVID-19 would be controlled successfully in Pakistan. The practices of wearing a mask (85.8%) and handwashing (88.1%) were common among the participants.
CONCLUSION: The participants demonstrated good knowledge and reasonable attitudes and practices toward most aspects of the COVID-19 outbreak. Improvements in certain areas could be made by mass-level education.
METHODS: The questionnaire was first developed in English language, and then assessed for its contents by a team of experts. It was then forwardly translated to Hausa, and backwardly translated again to English by independent language experts. These two English versions were then compared by a Public Health expert, following which the questionnaire was administered to 190 Hausa speaking antenatal care attendees. Exploratory factor analysis was performed on the data collected. Sixty three out of the 190 respondents were invited after 2 weeks to answer the same questionnaire, following which reliability tests were performed.
RESULTS: The questionnaire showed good internal consistency, with Cronbach's alpha values of 0.859, 0.890 and 0.773 for information, motivation and behavioural skills constructs respectively. The motivation and behavioural skills constructs were able to delineate their items into three and two sub-sections respectively. The factor loadings for the two constructs ranged from 0.610 to 0.965. As for test retest reliability, the Krippendorff's alpha values for the items of the motivation section ranged from 0.941 to 0.996; that for behavioural skills ranged from 0.810 to 0.953, while for frequency of ITN use, it was 0.988. The Cohen's kappa values for the information section ranged from 0.689-0.974, except the item for 'fever' (zazzabi) which was 0.382, and was as such reworded to a simpler terminology 'hotness of the body' (zafin jiki).
CONCLUSIONS: The Hausa language IMB questionnaire on malaria in pregnancy demonstrated good validity, and a high level of reliability. It is as such recommended for use among Hausa speaking communities to ensure uniformity and objectivity.
AIM: The purpose of this study is to perform a systematic review of the efficacy of Post-Mortem Computed Tomography (PMCT) scan compared with conventional autopsies gleaned from literature published in English between the year 2009 and 2016.
METHODOLOGY: A literature search was conducted in three databases, namely PubMed, MEDLINE, and Scopus. A total of 387 articles were retrieved, but only 21 studies were accepted after meeting the review criteria. Data, such as the number of victims, the number of radiologists and forensic pathologists involved, causes of death, and additional and missed diagnoses in PMCT scans were tabulated and analysed by two independent reviewers.
RESULTS: Compared with the conventional autopsy, the accuracy of PMCT scans in detecting injuries and causes of death was observed to range between 20% and 80%. The analysis also showed that PMCT had more advantages in detecting fractures, fluid in airways, gas in internal organs, major hemorrhages, fatty liver, stones, and bullet fragments. Despite its benefits, PMCT also could miss certain important lesion in a certain region such as cardiovascular injuries and minor vascular injuries.
CONCLUSIONS: This systematic review suggests that PMCT can replace most of the conventional autopsy in specific cases and is also a good complementary tool in most cases.
Methods: This is a cross-sectional study involving 156 TKA female patients with normal patellae. The patella height, width, thickness, medial and lateral articular facets' width and thickness, and the dome position were measured. The smallest implant size from 3 manufacturers was compared to the data obtained. Analysis using descriptive statistics was used to get the mean and median of anatomical patella dimensions, whereas the independent T test and one-way ANOVA test were used to compare the Malaysian female's patella dimensions with various implant sizes.
Results: The articular surface of the patella was found to have an oval shape with a width-height ratio of 1.31. The mean (SD) patella thickness, width, and height were 20.7 (1.85) mm, 40.7 (3.79) mm, and 31.3 (2.81) mm, respectively. Only 17.9% fit for smallest implant size from all 3 manufacturers. The oval-shape implant was suitable in 53.8% patients based on their width-height ratio. The dome position is 2.2 mm medial to centre.
Conclusion: These female patients have thinner and smaller patella, which are generally unable to accommodate patellar components based on the Caucasian database. Therefore, orthopaedic implant manufacturers should consider optimizing the thicknesses as well as widths of their patellar prostheses.
Materials and Methods: The authors prepared C. striatus extract in chloroform-methanol solvents. Next, the authors took subgingival microbiological samples from 16 cats that had periodontal disease. The authors determined the antibacterial properties of C. striatus extract against the isolated bacteria using the disk diffusion method and a broth microdilution-based resazurin microtiter assay. Finally, the authors used the Vero cell line to evaluate the cytotoxic activity, and they assessed the cell availability using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay.
Results: The results showed weak antibacterial activity of C. striatus extract against Pseudomonas spp. and Escherichia coli. In addition, the authors found that minimum inhibition concentration values ranged between 400 and 500 mg/mL, and minimum bactericidal concentration values ranged between 650 and 550 mg/mL. However, the cytotoxic results were promising, showing that C. striatus extract increased the cell viability and growth when it was at a higher concentration. The extract also promotes growth and cell proliferation.
Conclusion: These findings suggest that C. striatus extract promoted cell proliferation in vitro and could be a plausible therapeutic wound healing alternative for periodontal disease in cats.
Methods: The qualitative research approach was used to solicit and capture more in-depth information from participants. The research design was phenomenological in nature. A cross-sectional survey method was employed. The sample consisted of twenty female patients diagnosed with schizophrenia, seven psychiatrists, and seven psychologists. A semi-structured interview guide was developed to collect the data. The interview guide covered three themes. The first theme included four questions for patients with schizophrenia. The second theme consisted of six questions for the psychiatrists and the third theme included two questions for the psychologists. Interview data were analysed through frame workanalysis.
Results: The results of the study showed that social support plays an essential role in the improvement of patients with schizophrenia. Psychiatrists with the help of medication and therapies reduce the negativity and anxiety level of patients and motivate patients to accept treatment. Through counseling, psychologists help patients with schizophrenia build social skills such as the ability to engage in eye contact.
Conclusion: It is revealed that the social support is closely related to the willingness for treatment in patients with schizophrenia. Therefore, social support is recommended in the course of treatment of patients with schizophrenia.
Objective: To assess the periodontal status of pre-dialysis CKD patients in Hospital Universiti Sains Malaysia.
Methods: A total of 46 pre-dialysis CKD patients who attended the nephrology clinic at Hospital Universiti Sains Malaysia were enrolled in this study. Periodontal examination was performed using the periodontal probing depth (PPD), clinical attachment loss (CAL) and plaque index.
Results: The majority of the CKD patients were Malay (95.7%) and 80.4% were males. The mean age of the patients was 58.5 years. Using PPD measurement, 37 (74.0%) of the patients had mild periodontitis, 9 (20.0%) had moderate periodontitis and 3 (6.0%) had no periodontitis. Based on CAL measurement, 12 (26%) patients had mild periodontitis, 29 (63.0%) had moderate periodontitis and 5 (11%) had severe periodontitis. The mean (standard deviation [SD]) value of mild and moderate-to-severe periodontitis by PPD measurement were 4.26 (0.26) and 5.24 (0.36), respectively. The mean of mild and moderate-to-severe periodontitis by CAL measurement were 2.66 (0.62) and 4.98 (0.73), respectively. There was no correlation between the periodontal parameters and estimated glomerular filtration rate (PPD: r = -0.160, P = 0.914; CAL: r = -0.135, P = 0.372; plaque index: r = 0.005, P = 0.974).
Conclusion: This study revealed a greater prevalence and severity of chronic periodontitis among CKD patients. Thus, the periodontal health of CKD patients' needs to be screened and monitored.
