Purpose: This study aimed to assess factors associated with compliance and non-compliance among patients with tuberculosis (TB). Methods: A descriptive correlational study was conducted at the outpatient clinics of Abbassia Chest Hospital in Cairo, Egypt. A sample of 80 patients with TB who had been prescribed treatment regimens was recruited. Patients were interviewed using a structured form with fixed response options to identify factors associated with treatment compliance or non-compliance. Results: A significantly higher proportion of non-compliant patients (72.5%) experienced severe symptoms compared with patients in the compliant group (30.0%). Furthermore, most compliant patients (82.5%) demonstrated satisfactory overall knowledge of pulmonary TB, whereas only about half (52.5%) of patients in the non-compliant group did. This difference in knowledge level was statistically significant and was associated with treatment adherence. Among compliant patients, knowledge levels were also significantly influenced by age, sex, education, and employment status, a pattern that was not observed in the non-compliant group. Conclusion Key factors associated with non-compliance included insufficient income to support treatment, lack of home support for treatment regulation, and decreased motivation to improve health. These findings underscore the need for targeted patient education and counselling programs to increase disease awareness and improve treatment adherence among patients with TB.

COVID-19 is a highly contagious disease that caused a worldwide pandemic in 2020. Medical students are public advocates for COVID-19 vaccination to achieve herd immunity. Our objective is to ascertain the level of knowledge, attitude, and practice toward COVID-19 immunisation among medical students in Malaysia. The online study included four public universities in Peninsular Malaysia: Universiti Putra Malaysia, International Islamic University Malaysia, Universiti Sains Malaysia and Universiti Sains Islam Malaysia. Data collected include sociodemographic characteristics, history of COVID-19 infection, knowledge, attitude and practice towards COVID-19 immunisation. Analytical statistics were analysed with IBM Statistical Package Statistical Package for the Social Science (SPSS) v27.0 using Pearson chi-square or Fisher’s exact test (significant if p < 0.05). From the total of 427 respondents, 60.2% had good knowledge whereby clinical students 67.0% had a higher proportion of good knowledge as compared to preclinical students 53.5% (p = 0.004). Respondents in the age group of 21 to 24 years old (p < 0.001) and 25 to 29 years old (p = 0.016), and Indian ethnicity (p = 0.006) were more likely to have good knowledge. Respondents registered in Malaysia’s National COVID-19 vaccination program were considered as having a positive attitude (n = 264, 61.8%). A vaccination rate of 100% was observed. In conclusion, 60.2% of medical students had good knowledge, 61.8% had a positive attitude and 100% were vaccinated in these four public medical schools in Malaysia. Sociodemographic factors (age group and Indian ethnicity) have an association with only good knowledge but none with the level of attitude and practice towards COVID-19 immunisation.

Aims: Maternal vaginal Group B Streptococcus (GBS) colonization is considered a risk factor for preterm delivery and, consequently, neonatal infections. Previous studies have portrayed the important roles of these virulence factors, including hemolytic pigment, hyaluronidase (HylB), serine-rich protein (Srr) and bacterial surface adhesion of GBS (BsaB) in mediating GBS colonization and intrauterine ascending infection, causing preterm delivery. This study aimed to investigate the association between mRNA expression of virulence genes in GBS isolates obtained from symptomatic pregnant women and preterm delivery. Methodology and results: GBS isolates were obtained from high vaginal swabs of 40 symptomatic pregnant women of gestational age of less than 37 weeks. RNA was extracted from these GBS isolates and RT-qPCR was performed to determine the relative mRNA expression of GBS virulence genes, including CylE (encode enzyme required for the biosynthesis of the hemolytic pigment), HylB, Srr-1 and BsaB. Socio-demographic details and obstetric history were not found to be associated with the delivery outcomes of these women. The GBS isolates from symptomatic pregnant women who delivered prematurely showed a higher expression of CylE gene and a trend towards an elevated expression of HylB gene compared to women with term delivery. Meanwhile the expression of both Srr-1 and BsaB genes was similar between symptomatic pregnant women who had term or preterm delivery. Conclusion, significance and impact of study The results suggest that following vaginal colonization, both CylE and HylB genes are likely to contribute to intrauterine ascending infection and inflammation, leading to preterm delivery in humans. These virulence factors may be targeted for the pre-clinical stages of vaccine development or therapeutic intervention.

PURPOSE: This study aimed to evaluate the effect of incorporating zirconium oxide nanoparticles (nano-ZrO 2 ) in polymethylmethacrylate (PMMA) denture base resin on flexural properties at different material thicknesses. MATERIALS AND METHODS: Heat polymerized acrylic resin specimens (N = 120) were fabricated and divided into 4 groups according to denture base thickness (2.5 mm, 2.0 mm, 1.5 mm, 1.0 mm). Each group was subdivided into 3 subgroups (n = 10) according to nano-ZrO2 concentration (0%, 2.5%, and 5%). Flexural strength and elastic modulus were evaluated using a three-point bending test. One-way ANOVA, Tukey’s post hoc, and two-way ANOVA were used for data analysis (α = .05). Scanning electron microscopy (SEM) was used for fracture surface analysis and nanoparticles distributions. RESULTS: Groups with 0% nano-ZrO2 showed no significant difference in the flexural strength as thickness decreased (P = .153). The addition of nano-zirconia significantly increased the flexural strength (P < .001). The highest value was with 5% nano-ZrO2 and 2 mm-thickness (125.4± 18.3 MPa), followed by 5% nano-ZrO2 and 1.5 mm-thickness (110.3 ± 8.5 MPa). Moreover, the effect of various concentration levels on elastic modulus was statistically significant for 2 mm thickness (P = .001), but the combined effect of thickness and concentration on elastic modulus was insignificant (P = .10). CONCLUSION Reinforcement of denture base material with nano-ZrO2 significantly increased flexural strength and modulus of elasticity. Reducing material thickness did not decrease flexural strength when nano-ZrO2 was incorporated. In clinical practice, when low thickness of denture base material is indicated, PMMAano-ZrO2 could be used with minimum acceptable thickness of 1.5 mm.

PURPOSE: This study aimed to evaluate the impact of a lifestyle modification program on menstrual irregularity among overweight and obese women with polycystic ovarian syndrome. METHODS: A quasi experimental research design was used to conduct this study on 82 women with polycystic ovarian syndrome at the Gynecology and Obesity clinics of Mansoura University Hospital, Egypt. Two groups were included; the study group received a lifestyle modification program for 48 weeks, while the control group was not subjected to this program. Data collection was done for the following variables, a structured interview questionnaire was used to assess the women's general characteristics, menstrual patterns, and 24-hour dietary recall and the researcher took anthropometric measurements and assessed hirsutism by the Ferriman-Gallwey scale. RESULTS: After one year of lifestyle modification, the number of menstrual cycles significantly increased from 2.7+/-1.6 to 6.9+/-1.5 (t=12.26, p<.001) in the study group compared to insignificant minor changes among the control group (t=0.69, p=.488). Additionally, 58.5% were menstruating regularly compared to none in the control group (chi2=33.93, p<.001). CONCLUSION: Participating in a lifestyle modification program was effective in reducing menstrual cycle's irregularity among overweight and obese women with PCOS. Thus, it is recommended to motivate the nurses in counseling the PCOS women on lifestyle modifications.
