ABSTRACT

BACKGROUND: The morbidity and mortality of colorectal cancer (CRC) remain high, posing a serious threat to human life and health. The early diagnosis and prognostic evaluation of CRC are two major challenges in clinical practice. MTUS1 is considered a tumour suppressor and can play an important role in inhibiting cell proliferation, migration, and tumour growth. Moreover, the expression of MTUS1 is decreased in different human cancers, including CRC. However, the biological functions and molecular mechanisms of MTUS1 in CRC remain unclear.

METHODS: In the present study, data from The Cancer Genome Atlas (TCGA) database were analysed using R statistical software (version 3.6.3.) to evaluate the expression of MTUS1 in tumour tissues and adjacent normal tissues using public databases such as the TIMER and Oncomine databases. Then, 38 clinical samples were collected, and qPCR was performed to verify MTUS1 expression. We also investigated the relationship between MTUS1 expression and clinicopathological characteristics and elucidated the diagnostic and prognostic value of MTUS1 in CRC. In addition, the correlation between MTUS1 expression and immune infiltration levels was identified using the TIMER and GEPIA databases. Furthermore, we constructed and analysed a PPI network and coexpression modules of MTUS1 to explore its molecular functions and mechanisms.

RESULTS: CRC tissues exhibited lower levels of MTUS1 than normal tissues. The logistic regression analysis indicated that the expression of MTUS1 was associated with N stage, TNM stage, and neoplasm type. Moreover, CRC patients with low MTUS1 expression had poor overall survival (OS). Multivariate analysis revealed that the downregulation of MTUS1 was an independent prognostic factor and was correlated with poor OS in CRC patients. MTUS1 expression had good diagnostic value based on ROC analysis. Furthermore, we identified a group of potential MTUS1-interacting proteins and coexpressed genes. GO and KEGG enrichment analyses showed that MTUS1 was involved in multiple cancer-related signalling pathways. Moreover, the expression of MTUS1 was significantly related to the infiltration levels of multiple cells. Finally, MTUS1 expression was strongly correlated with various immune marker sets.

CONCLUSIONS: Our results indicated that MTUS1 is a promising biomarker for predicting the diagnosis and prognosis of CRC patients. MTUS1 can also become a new molecular target for tumour immunotherapy.

ABSTRACT

BACKGROUND: Excessive screen time in infancy and childhood has been associated with consequences on children’s development and health. International guidelines call for no screen time before age 2 years, whereas in France, the most prominent guidelines recommend no screen before age 3 years. However, data are lacking on parental adherence to the no-screen guideline for toddlers and factors of adherence in France. Using data from the French nationwide Elfe birth cohort, we estimated adherence to the no-screen guideline at age 2 years and examined related factors, including sociodemographic characteristics, parental leisure activities and screen time.

METHODS: In 2011, 18,329 newborns and their parents were enrolled in 349 randomly selected maternity units across mainland France. At age 2 years, screen exposure of 13,117 toddlers was reported by parents in phone interviews. Data on sociodemographic characteristics, parental leisure activities and screen time were collected from both parents. Three patterns of parental leisure activities were derived by principal component analysis: literate (e.g.,reading), screen-based, and physical/artistic activities. Multivariable logistic regression models were used to examine the associations of sociodemographic characteristics, parental leisure activities and parental screen time with adherence to the no-screen guideline for toddlers.

RESULTS: Overall, 1809/13,117 (13.5%) families adhered to the no-screen guideline for toddlers. Adherence was reduced with maternal age < 40 years, low parental education, single-parent household and parental migration status. After adjusting for sociodemographic characteristics, adherence to the guideline was positively associated with a parental literate activity pattern (mothers: odds ratio [95% confidence interval]: 1.15 [1.08, 1.22]); fathers: 1.15 [1.07, 1.23]) and negatively with a screen-based activity pattern (mothers: 0.73 [0.69, 0.77]; fathers: 0.81 [0.76, 0.87]). With each additional hour of parental screen time, mothers and fathers were less likely to adhere to the guideline (mothers: adjusted odds ratio 0.80 [0.77, 0.83]; fathers: 0.88 [0.85, 0.91]).

CONCLUSIONS: Adherence to the no-screen guideline for toddlers in France was low. Parental leisure activities and parental screen time are major factors of adherence to the no-screen guideline and could be considered in targeted public health interventions.

ABSTRACT

BACKGROUND: Social integration and perceived neighborhood environment are recognized as important social determinants of health. However, little is known about the association between social integration and perceived neighborhood environment among underrepresented population groups, such as residents in disadvantaged neighborhoods, in public health research. The aim of this study is to: 1) Describe the levels of social integration and 2) Investigate the association between social integration and neighborhood dissatisfaction and unsafety among middle-aged and older social housing residents.

METHODS: A multilingual face-to-face interviewer-administrated survey questionnaire was conducted among 206 residents aged 45 years and above (response rate: 34.1%) of various nationalities in disadvantaged socioeconomic positions in a social housing area in Denmark. The assessment of social integration was based on cohabitation status, frequency of face-to-face and non-face-to-face interaction with social relations and participation in local association activities. Neighborhood dissatisfaction measured the level of dissatisfaction with the neighborhood, and neighborhood unsafety assessed the level of unsafety being outdoors in the neighborhood. Descriptive statistics were conducted to illustrate respondent characteristics and the distribution of social integration among the study population. Logistic regression models were applied to analyze associations between social integration and neighborhood dissatisfaction and unsafety, adjusted for age, sex, country of origin, educational attainment and employment status.

RESULTS: In total, 23.8% of the respondents reported low levels of social integration. A medium level of social integration was associated with higher odds of neighborhood dissatisfaction (OR: 2.36; 95% CI: 1.04-5.38) compared to the highest level of integration. A low frequency of face-to-face interaction was associated with higher odds of neighborhood dissatisfaction (OR: 2.65; 95% CI: 1.16-6.06) and neighborhood unsafety (OR: 2.41; 95% CI: 1.04-5.57) compared to the highest frequency of face-to-face interaction.

CONCLUSIONS: Almost one-fourth of respondents reported low levels of social integration. A medium level of social integration was associated with neighborhood dissatisfaction. A low frequency of face-to-face interaction was associated with neighborhood dissatisfaction and unsafety. The results suggest that targeted health promotion interventions designed to foster face-to-face interaction, hold potential to reduce neighborhood dissatisfaction and unsafety among residents in disadvantaged neighborhoods.

ABSTRACT

BACKGROUND: Several studies have suggested that the addition of iPACK block (the popliteal artery and the posterior knee capsule have been given interspace local anesthetic infiltration) might get better analgesia than adductor canal block (ACB) only after total knee arthroplasty (TKA). This paper compiles all available evidence on the effect of two analgesia regimens (ACB and iPACK + ACB) involving all sides.

METHODS: We searched in eight major databases for all clinical trials discussing the effect of two analgesia regimens after TKA. Statistical analyses were conducted by Stata and RevMan Software. In addition, we performed GOSH analysis, subgroup analysis, meta-regression analysis to study the source of heterogeneity. Publication bias was checked using Egger’s test. Trim-and-fill analysis was applied in terms of sensitivity analysis of the results.

RESULTS: There are fourteen eligible studies for our meta-analysis. There are significant differences between the two groups in VAS score at rest and with activity, and the VAS scores were lower in the ACB + iPACK Group (VAS scores at rest: 95%CI [- 0.96, – 0.53], P < 0.00001. VAS scores with activity: 95%CI [- 0.79, – 0.43], P < 0.00001). A differential was discovered to support the ACB + iPACK Group when comparing the two groups on postoperative cumulative morphine consumption (95%CI: [- 0.52, – 0.14], P: 0.0007). The patients in the group of ACB + iPACK performed better in the postoperative range of knee movement (95%CI: [5.18, 10.21], P < 0.00001) and walking distance (95%CI: [0.15, 0.41], P < 0.00001). There were significant differences between the patients in the ACB + iPACK Group and ACB Group on the TUG test of POD1 and POD2. We found that patients’ hospital stays in the ACB + iPACK Group were significantly shorter than in the ACB Group (95%CI: [- 0.78, – 0.16], P: 0.003). No difference was found between the patients in the ACB + iPACK Group and ACB Group on postoperative quadriceps muscle strength and the incidence of PONV.

CONCLUSION: The addition of iPACK lowers postoperative VAS scores, cumulative morphine consumption, and hospital stays. Meanwhile, the addition of iPACK improves postoperative patients’ activity performance without extra side effects. iPACK combined with ACB proves to be a suitable pain management technique after TKA.

ABSTRACT

BACKGROUND: Death literacy includes the knowledge and skills that people need to gain access to, understand, and make informed choices about end of life and death care options. The Death Literacy Index (DLI) can be used to determine levels of death literacy across multiple contexts, including at a community/national level, and to evaluate the outcome of public health interventions. As the first measure of death literacy, the DLI has potential to significantly advance public health approaches to palliative care. The current study aimed to provide the first assessment of the psychometric properties of the DLI in the UK, alongside population-level benchmarks.

METHODS: A large nationally representative sample of 399 participants, stratified by age, gender and ethnicity, were prospectively recruited via an online panel. The factor structure of the 29-item DLI was investigated using confirmatory factor analysis. Internal consistency of subscales was assessed alongside interpretability. Hypothesised associations with theoretically related/unrelated constructs were examined to assess convergent and discriminant validity. Descriptive statistics were used to provide scaled mean scores on the DLI.

RESULTS: Confirmatory factor analysis supported the original higher-order 8 factor structure, with the best fitting model including one substituted item developed specifically for UK respondents. The subscales reported high internal consistency. Good convergent and discriminant validity was evidenced in relation to objective knowledge of the death system, death competency, actions relating to death and dying in the community and loneliness. Good known-groups validity was achieved with respondents with professional/lived experience of end-of-life care reporting higher levels of death literacy. There was little socio-demographic variability in DLI scores. Scaled population-level mean scores were near the mid-point of DLI subscale/total, with comparatively high levels of experiential knowledge and the ability to talk about death and dying.

CONCLUSIONS: Psychometric evaluations suggest the DLI is a reliable and valid measure of death literacy for use in the UK, with population level benchmarks suggesting the UK population could strengthen capacity in factual knowledge and accessing help. International validation of the DLI represents a significant advancement in outcome measurement for public health approaches to palliative care. PRE-REGISTRATION: https://osf.io/fwxkh/.

ABSTRACT

BACKGROUND: This study aimed to investigate the associations between the triglyceride-glucose (TyG) index in young adulthood with incident cardiovascular disease (CVD) and mortality.

METHODS: We included 4,754 participants from the Coronary Artery Risk Development in Young Adults study at baseline. The TyG index was calculated as ln (fasting TG [mg/dl] × fasting glucose [mg/dl]/2), and the TyG index trajectories were identified by using the latent class growth mixture model. We evaluated the association between the baseline and trajectories of the TyG index with incident CVD events and all-cause mortality using Cox proportional hazards regression analysis. The added value of the TyG index included in pooled cohort equations for CVD prediction was also analyzed.

RESULTS: Among 4754 participants (mean age 24.72 years, 45.8% male, 51.2% black), there were 158 incident CVD events and 246 all-cause mortality during a median 25 years follow-up. After adjusting for multiple confounding variables, each one-unit increase in the TyG index was associated with a 96% higher CVD risk (hazard ratio [HR] 1.96, 95% confidence interval [CI] 1.44-2.66) and a 85% higher all-cause mortality risk (HR 1.85, 95% CI 1.45-2.36). Three distinct trajectories of the TyG index along the follow-up duration were identified: low (44.0%), moderate (45.5%), and high (10.5%). Compared with those participants in the low TyG index trajectory group, those in the high TyG index trajectory group had a greater risk of CVD events (HR 2.35, 95% CI 1.34-4.12) and all-cause mortality (HR 3.04, 95% CI 1.83-5.07). The addition of baseline TyG index to pooled cohort equations for CVD improved the C-statistics (P < 0.001), integrated discrimination improvement value (P < 0.001), and category-free net reclassification improvement value (P = 0.003).

CONCLUSIONS: Higher baseline TyG index levels and higher long-term trajectory of TyG index during young adulthood were significantly associated with an increased risk of incident CVD events and all-cause mortality in later life.

ABSTRACT

BACKGROUND: Neisseria gonorrhoeae, the causative agent for sexually transmitted infection (STI) gonorrhoea, has emerged with a significant public health impact on acquiring resistance to antimicrobials available for treatment. The resistance of N. gonorrhoeae limit treatment options and contributed to high morbidity associated with gonorrhoea. Data on antimicrobial resistance (AMR) profiles in N. gonorrhoeae is scares in Zambia. This study aimed to determine the antibiotic susceptibilities in N. gonorrhoeae isolates from Lusaka, Zambia.

METHODS: A prospective cross-sectional study was conducted on 630 STI patients who presented with urethral or vaginal discharge from 2019 to 2020. Urethral and endocervical secretions were cultured on Modified Thayer Martin agar and incubated at 36 °C ± 1 °C in 5% CO₂ for 24 h. Identification of N. gonorrhoeae isolates was achieved by Gram stain, oxidase, nitrocefin disk, BactiCard Neisseria, and Viteck® Compact. The AMR profiles were determined using E-test. Statistical significant was determined by Pearson’s Chi-square test, Mann-Whitney U test, or logistic regression with p-values of < 0.05 indicating significance.

RESULTS: A total of 630 patients were recruited of which 46% (290/630) with the median of 29 years and interquartile range (IQR) of 19-39 years were male. The median of the females was 26 years and IQR of 15-37 years. Neisseria gonorrhoeae was isolated from 19.4% (122/630) patients of which 72.9% (89/122) were male, with highest prevalence of isolation in the age category of 25-34 years. The prevalence of resistance was high to penicillin (85.2%), tetracycline (68.9%) and ciprofloxacin (59.8%) with MIC₉₀ of 32 µg/mL, 8 µg/mL, and 8 µg/mL respectively. The isolates had reduced susceptibility to cefixime (1.6%), spectinomycin (4.9%) and (4.9%) for azithromycin. All isolates were susceptible to ceftriaxone. Risk factors associated with AMR were douching in females (AOR 6.69, 95% CI; 1.11-40.31, p = 0.039), female gender (AOR 7.64, 95% CI; 1.11-52.33, p = 0.048), HIV-positivity (AOR 26.59, 95% CI; 3.67-192.7, p = 0.005), no condom use or unprotected sex (AOR 5.48, 95% CI; 1.17-22.75 p = 0.026), sex trading (AOR 4.19, 95% CI; 1.55-11.33, p = 0.010), and over-counter treatment of ciprofloxacin (AOR 3.44, 95% CI; 1.17-22.75, p = 0.023).

CONCLUSION: The N. gonorrhoeae resistance to penicillin, tetracycline and ciprofloxacin was high necessitating revision of the treatment guidelines. However, no resistance to ceftriaxone was detected. Therefore, monitoring of antibiotic resistance remains critical in Zambia.

ABSTRACT

BACKGROUND: Functional recovery is an important treatment goal in major depressive disorder (MDD). This study assessed the real-world effectiveness of vortioxetine in patients with MDD, with particular focus on functioning; dose-response was also assessed.

METHODS: This was a non-interventional, prospective, multicenter study conducted in Greece. Adult outpatients with MDD (n = 336) initiating vortioxetine (5-20 mg/day flexible dosing) as treatment for a current major depressive episode were followed for 3 months. Analyses were stratified according to vortioxetine dosage at 3 months: 5-10 mg/day versus 15-20 mg/day. Functioning was assessed using the Sheehan Disability Scale (SDS).

RESULTS: Mean ± standard error SDS total score decreased (improved) from 18.7 ± 0.3 at baseline to 12.9 ± 0.3 after 1 month of vortioxetine treatment and 7.8 ± 0.4 after 3 months (p < 0.001 vs. baseline for all comparisons). Functional recovery (SDS score ≤ 6) was achieved in 14.6% of patients after 1 month of treatment and 48.4% of patients after 3 months. Improvement from baseline in SDS total and domain scores at 3 months was more pronounced in patients receiving vortioxetine 15-20 mg/day than in those receiving vortioxetine 5-10 mg/day. The mean ± standard error change in SDS total score from baseline was 9.2 ± 0.8 in the 5-10 mg/day group and 12.1 ± 0.4 in the 15-20 mg/day group (p < 0.001). Limitations of this study include its non-interventional study design and lack of a control group or active comparator.

CONCLUSIONS: Statistically significant and clinically relevant improvements in functioning were seen in patients with MDD treated with vortioxetine in a real-world setting. Higher doses of vortioxetine were associated with significantly greater improvements in functioning.

ABSTRACT

BACKGROUND: Globally, the usage of herbal medicines (HMs) is increasingly growing in treating and preventing various ailments. Although, HMs play a vital role in healthcare, concerns have been raised over their safety. Since pharmacy professionals are at the right position to provide patients with evidence-based information on herbals, they should be knowledgeable enough on the subject matter. Thus, the aim of the study was to assess the knowledge, attitude and prevalence of HMs use and its associated factors among pharmacy professionals.

METHOD: An analytical cross-sectional study was conducted among pharmacy professionals working in drug retail outlets in Asmara (the capital city of Eritrea). A census design was employed and data were collected through face-to-face interview. Data were entered and analyzed using Census and Survey Processing System (version-7.2) and IBM Statistical Package for Social Sciences (version 26), respectively. Descriptive and analytical statistics including Mann-Whitney U test/Kruskal-Wallis test and logistic regression were employed. P-values less than 0.05 were considered as significant.

RESULTS: A total of 50 pharmacy professionals (90.9% response rate) were enrolled in the study. Majority of them (62%) were males and two-thirds had a bachelor’s degree. The overall median (Interquartile range, IQR) knowledge score was found to be 24 (12.16) out of 100 with a minimum score of 8 and maximum score of 53. Generally, the median (IQR) attitude score was 70.4 (4.2) out of 100. Majority (78%) of them had used HM for self-treatment. Only religion was found to be a significant determinant of knowledge on indication of HMs (p = 0.015), while attitude score was independent of the potential determining factors. Moreover, prevalence of use was significantly associated with pharmacy ownership (Adjusted Odds Ratio (AOR) =14.44, 95%Confidence Interval (CI): 1.67, 124.52) as well as with the percentage attitude score (AOR = 0.632, 95%CI: 0.41, 0.96) at multivariable level.

CONCLUSION: Generally, the overall knowledge score of pharmacy professionals was low. However, they possessed positive attitude towards herbal medicines. Besides, there was prevalent usage of herbal medicine for self-treatment. This outcome triggers the need for educational courses and workshops centered on herbal medicine.

ABSTRACT

BACKGROUND: The present study aimed to assess the impact of application of fluoridated- 10% carbamide peroxide (CP) with or without potassium iodide (KI) on silver diamine fluoride (SDF)-treated enamel surface in the primary teeth.

METHODS: After stained-remineralized caries lesions (s-RCLs) creation, 96 teeth were randomly allocated to four experimental groups: Group 1:SDF-treated enamel followed by 8-h/day application of 10% CP for 2 weeks; Group 2: SDF-treated enamel followed by 15-min/day application of 10% CP for 3 weeks; Group 3: SDF + KI-treated enamel followed by 8-h/day application of 10% CP for 2 weeks; and Group 4: SDF + KI-treated enamel followed by 15-min/day application of 10% CP for 3 weeks. Enamel microhardness (EMH) test (n = 12) and spectrophotometric color assessment (n = 12) was performed at four stages: baseline (intact enamel), demineralized enamel, aged remineralized-stained enamel, and after final intervention. Sixteen samples were used for SEM evaluation. Data were analyzed with the paired t-test, one-way ANOVA, and Tukey’s post-hoc test (p < 0.05).

RESULTS: EMH values in all groups showed significant decrease after demineralization (all, p < 0.00001). All samples showed complete recovery of EMH values (%REMH) after SDF application compared to demineralization (%REMH_SDF) (p = 0.971). Bleaching caused a slight decrease in %REMH for all groups. However, the differences were not statistically significant (p = 0.979). SEM findings revealed no changes in enamel porosity after bleaching. Bleaching application ameliorated the discoloration in all groups (all, p < 0.00001). All samples in Groups 2 and 4 had significantly lighter color after 21 days as compared to 14-day exposure to the bleaching material (both, p < 0.00001).

CONCLUSIONS: SDF application on demineralized primary tooth enamel completely recovered enamel microhardness. 10% carbamide peroxide effectively bleached SDF stain without causing significant decrease in EMH values. Color improvement was more evident with the use of KI immediately after SDF application. Both 15-min and 8-h application of fluoridated CP resulted in statistically similar color enhancement in primary teeth.
