ABSTRACT

BACKGROUND/AIMS: : Bismuth-based quadruple therapy (BQT) is a treatment option for clarithromycin-resistant Helicobacter pylori (HP) infection. The aim of this study was to compare the efficacy of 7-day BQT with that of 14-day BQT as first-line treatment for clarithromycin-resistant HP infection.

METHODS: : A total of 162 treatment-naïve patients with peptic ulcer disease and clarithromycin-resistant HP infection confirmed by real-time polymerase chain reaction (RT-PCR) were enrolled. The enrolled patients were prospectively randomized to receive BQT for either 7 or 14 days of treatment. Eradication of HP infection was assessed using a ¹³C-urea breath test. Eradication and adverse event rates of the two groups were assessed.

RESULTS: : The overall eradication rates in the intention-to-treat (ITT) and per-protocol (PP) analyses were 83.0% (95% confidence interval [CI], 77.2% to 88.9%; 132/159) and 89.8% (95% CI, 84.9% to 94.7%; 132/147), respectively. The eradication rates in the ITT analysis were 79.0% (64/81) in the 7-day group and 87.2% (68/78) in the 14-day group (p=0.170). The eradication rates in the PP analysis were 86.5% (64/74) in the 7-day group and 93.2% (68/73) in the 14-day group (p=0.182). Clinically significant adverse events occurred in 18.2% of patients. There was no statistically significant difference in the rates of individual or all adverse events between the two groups.

CONCLUSIONS: : Both 7-day and 14-day BQT were effective and safe as first-line therapy for HP infections identified as resistant to clarithromycin by RT-PCR. For clarithromycin-resistant HP infections, 7-day BQT may be sufficient as first-line therapy.

ABSTRACT

BACKGROUND: Multiple-choice examinations are frequently employed among German dental schools. However, details regarding the used item types and applied scoring methods are lacking.

OBJECTIVE: We aimed to gain an insight into the current usage of multiple-choice items (ie, questions) in summative examinations in German undergraduate dental training programmes.

METHODS: A paper-based 10-item questionnaire regarding the employed assessment methods, multiple-choice item types, and applied scoring methods was designed. The pilot-tested questionnaire was mailed to the Deans of Studies and to the Heads of Department of Operative/Restorative Dentistry at all 30 dental schools in Germany in February 2023. Statistical analysis was performed using Fisher’s exact test (P<.05).

RESULTS: The response rate amounted to 90.0% (27/30 dental schools). All respondent dental schools employed multiple-choice examinations for summative assessments. Examinations were delivered electronically by 70.4% (19/27) of the dental schools. Almost all dental schools used single-choice Type A items (88.9%) which accounted for the largest number of items in about half of the dental schools. Further item types (eg, conventional multiple-select items, Multiple-True-False, Pick-N) were only used by fewer dental schools (≤66.7%, up to 18 out of 27 dental schools). For the multiple-select item types, the applied scoring methods varied considerably (ie, awarding [intermediate] partial credit, requirements for partial credit). Dental schools with the possibility of electronic examinations used multiple-select items slightly more often (73.7%, 14/19 vs. 50.0%, 4/8). However, this difference was statistically not significant (P=.375). Dental schools used items either individually or as key feature problems consisting of a clinical case scenario followed by a number of items focusing on critical treatment steps (55.6%, 15/27). Not a single school employed alternative testing methods (eg, answer-until-correct). A formal item review process was established at about half of the dental schools (55.6%, 15/27).

CONCLUSIONS: Summative assessment methods among German dental schools vary widely. Especially, a large variability regarding the use and scoring of multiple-select multiple-choice items was found.

ABSTRACT

BACKGROUND: Andrographolide (AP), a bioactive anti-inflammatory compound of Sambiloto, inhibits NF-κB, TNF-α, and interleukin IL-6. Nowadays, molecular docking simulation between AP and dexamethasone against NF-κB receptor presented the energy AP higher than dexamethasone. This becomes a potential treatment for psoriasis.

OBJECTIVE: This manuscript reported the effectiveness of AP from Sambiloto in treating psoriasis compared to topical steroids.

METHODS: This study conducted TLC analysis of AP content and its metabolite impurities, emulgel formulation, molecular docking, in-silico skin toxicity study, and in-vivo anti-psoriatic activity. This was a combination study of an in-silico study and an in-vivo study. This in-silico study was analyzed through multivariate statistical analysis (PCA) to elucidate the data constellation relationship of andrographolide derivatives with several target proteins. The intervention was performed in seven days. The PASI score, molecular parameters (IL-6, IL-17, VEGF, and TNF-a levels), and histopathological findings were assessed.

RESULTS: Molecular docking results revealed andrographolide to exhibit a relatively high binding affinity towards IL-6, NF-kB, and TNF-α which is comparable to the corticosteroids, andrographolide also shares similar residue interaction profile with each of the respective protein’s native ligand. In the in-vivo study, we found several parameters statistically significantly different regarding the intervention, including final PASI score (p = 0.017), redness (p = 0.017), scale (p = 0.040), thickness (p = 0.023), total histopathology of psoriasis score (p = 0.037), keratin layer score (p = 0.018).

CONCLUSION: Emulgel AP 0.1% could lower the anti-inflammatory agent, which is vital to psoriasis progression.

ABSTRACT

OBJECTIVE: The purpose of this retrospective archival study was to explore the clinical utility of the Judgment subtest of the Neuropsychological Assessment Battery (NAB) in older adults who were referred because of cognitive concerns. Specifically, we were interested in how NAB Judgment covaried with other measures of executive functioning.

METHOD: 226 adults, aged 61-89 years (48% dementia, 35% mild cognitive impairment, 18% cognitively intact) completed NAB Judgment. They also completed Trail Making Test (TMT) A and B. In addition, Behavior Rating Inventory of Executive Function (BRIEF-A) informant and self-reports were obtained to measure executive functioning in daily life.

RESULTS: Scores on NAB Judgment did not correlate significantly with BRIEF-A informant ratings. However, there was a statistically significant correlation between BRIEF-A informant ratings and TMT B. Better performance on TMT B was associated with fewer informant concerns. Furthermore, subgroups with versus without informant BRIEF-A Metacognition indices in the range of impairment demonstrated a statistically significant difference on TMT B but not on Judgment.

CONCLUSIONS: Executive functioning in older adults should not be assessed using NAB Judgment alone. Such an evaluation should be supplemented with other in-person tests as well as informant ratings of daily functioning.

ABSTRACT

INTRODUCTION: The escalating incidence of anterior cruciate ligament (ACL) injuries, particularly among adolescents, is a pressing concern. The study of ACL biomechanics in this demographic presents challenges due to the scarcity of cadaveric specimens. This research endeavors to validate the adolescent porcine stifle joint as a fitting model for ACL studies.

METHODS: We conducted experiments on 30 fresh porcine stifle knee joints. (Breed: Yorkshire, Weight: avg 90 lbs, Age Range: 2-4 months). They were stored at – 22 °C and a subsequent 24-h thaw at room temperature before being prepared for the experiment. These joints were randomly assigned to three groups. The first group served as a control and underwent only the load-to-failure test. The remaining two groups were subjected to 100 cycles, with forces of 300N and 520N, respectively. The load values of 300N and 520N correspond to three and five times the body weight (BW) of our juvenile porcine, respectively.

RESULT: The 520N force demonstrated a higher strain than the 300N, indicating a direct correlation between ACL strain and augmented loads. A significant difference in load-to-failure (p = 0.014) was observed between non-cyclically loaded ACLs and those subjected to 100 cycles at 520N. Three of the ten samples in the 520N group failed before completing 100 cycles. The ruptured ACLs from these tests closely resembled adolescent ACL injuries in detachment patterns. ACL stiffness was also measured post-cyclical loading by applying force and pulling the ACL at a rate of 1 mm per sec. Moreover, ACL stiffness measurements decreased from 152.46 N/mm in the control group to 129.42 N/mm after 100 cycles at 300N and a more significant drop to 86.90 N/mm after 100 cycles at 520N. A one-way analysis of variance (ANOVA) and t-test were chosen for statistical analysis.

CONCLUSIONS: The porcine stifle joint is an appropriate model for understanding ACL biomechanics in the skeletally immature demographic. The results emphasize the ligament’s susceptibility to injury under high-impact loads pertinent to sports activities. The study advocates for further research into different loading scenarios and the protective role of muscle co-activation in ACL injury prevention.

ABSTRACT

PURPOSE: This study aimed to investigate an early diagnostic method for lumbar disc degeneration (LDD) and improve its diagnostic accuracy.

METHODS: Quantitative biomarkers of the lumbar body (LB) and lumbar discs (LDs) were obtained using nuclear magnetic resonance (NMR) detection technology. The diagnostic weights of each biological metabolism indicator were screened using the factor analysis method.

RESULTS: Through factor analysis, common factors such as the LB fat fraction, fat content, and T2* value of LDs were identified as covariates for the diagnostic model for the evaluation of LDD. This model can optimize the accuracy and reliability of LDD diagnosis.

CONCLUSION: The application of biomarker quantification methods based on NMR detection technology combined with factor analysis provides an effective means for the early diagnosis of LDD, thereby improving diagnostic accuracy and reliability.

ABSTRACT

BACKGROUND: Systemic Lupus Erythematosus (SLE) and Osteoporosis are two prevalent medical conditions. Previous studies have suggested a possible correlation between SLE and osteoporosis, though the underpinning causal relationship remains largely unknown. The current study aimed to elucidate the causal association between SLE and osteoporosis by employing a Mendelian randomization (MR) approach.

METHODS: We performed two-sample MR analysis using the inverse variance-weighted (IVW), weighted median, and MR-Egger methods on publicly available summary statistics datasets using a SLE genome-wide association study (GWAS) as an exposure and osteoporosis GWASs in people with East Asia ancestry as outcomes. The pleiotropy and heterogeneity were examined using a variety of techniques, including the MR-Egger intercept, the MR-PRESSO approach, and the Cochran’s Q test.

RESULTS: We selected 26 single-nucleotide polymorphisms from a SLE GWAS as instrumental variables for osteoporosis. The IVW (p < 0.05) method results support a potential association between SLE and osteoporosis. MR-Egger intercept (p = 0.82) and MR-PRESSO global test (p = 0.80) did not suggest evidence of horizontal or directional pleiotropy. Cochran’s Q test (p = 0.78) showed that there was no heterogeneity between IVs.

CONCLUSION: The results of MR analysis indicated that SLE is likely associated with an increased risk of osteoporosis incidence. Our findings highlight the need for increased awareness the potential risk of osteoporosis among SLE patients.

ABSTRACT

BACKGROUND: Previous literature has explored the relationship between chronic atrophic gastritis (CAG) and isolated cancers within the upper gastrointestinal cancers; However, an integrative synthesis across the totality of upper gastrointestinal cancers was conspicuously absent. The research objective was to assess the relationship between CAG and the risk of incident upper gastrointestinal cancers, specifically including gastric cancer, oesophageal cancer, and oesophagogastric junction cancer.

METHODS: Rigorous systematic searches were conducted across three major databases, namely PubMed, Embase and Web of Science, encompassing the timeline from database inception until August 10, 2023. We extracted the necessary odds ratio (OR) and their corresponding 95% confidence interval (CI) for subsequent meta-analysis. Statistical analyses were conducted using Stata 17.0 software.

RESULTS: This meta-analysis included a total of 23 articles encompassing 5858 patients diagnosed with upper gastrointestinal cancers. CAG resulted in a statistically significant 4.12-fold elevated risk of incident gastric cancer (OR = 4.12, 95% CI 3.20-5.30). Likewise, CAG was linked to a 2.08-fold increased risk of incident oesophageal cancer (OR = 2.08, 95%CI 1.60-2.72). Intriguingly, a specific correlation was found between CAG and the risk of incident oesophageal squamous cell carcinoma (OR = 2.29, 95%CI 1.77-2.95), while no significant association was detected for oesophageal adenocarcinoma (OR = 0.62, 95%CI 0.17-2.26). Moreover, CAG was correlated with a 2.77-fold heightened risk of oesophagogastric junction cancer (OR = 2.77, 95%CI 2.21-3.46). Notably, for the same type of upper gastrointestinal cancer, it was observed that diagnosing CAG through histological methods was linked to a 33-77% higher risk of developing cancer compared to diagnosing CAG through serological methods.

CONCLUSION: This meta-analysis indicated a two- to fourfold increased risk of gastric cancer, oesophageal cancer, and oesophagogastric junction cancer in patients with CAG. Importantly, for the same upper gastrointestinal cancer, the risk of incident cancer was higher when CAG was diagnosed histologically compared to serological diagnosis. Further rigorous study designs are required to explore the impact of CAG diagnosed through both diagnostic methods on the risk of upper gastrointestinal cancers.

ABSTRACT

BACKGROUND: Periodontitis is a complex chronic inflammatory disease that is particularly associated with health-related conditions such as smoking, excessive drinking and depression. This research aimed to investigate the interaction between these lifestyles factors on periodontitis risk.

METHODS: This study included participants who participated in the National Health and Nutrition Examination Survey in the United States between 2009 and 2014. They had completed oral health-periodontal examination, Smoking-Cigarette Use Questionnaire, Alcohol Use Questionnaire, and Patient Health Questionnaire. Periodontal clinical attachment loss (CAL) of 3 mm or more and Patient Health Questionnaire-9 (PHQ-9) of 10 scores or more were used to identify periodontitis and depression, respectively. Daily alcohol consumption in the past year was classified into three levels: low (1 drink or less), moderate (between 1 and 3 drinks), and heavy drinking (4 drinks or more), while smoking was defined as having smoked at least 100 cigarettes in one’s lifetime. Then, the logistic regression combined with interaction models were used to analyze the independent and combined effects of smoking, drinking and depression on periodontitis risk.

RESULTS: The results indicated a statistically significant multiplicative interaction between smoking and depression in relation to the development of periodontitis, both in the overall population (P = 0.03) and among male participants (P = 0.03). Furthermore, among individuals experiencing depression, smoking was found to significantly increase the prevalence of periodontitis by 129% in the younger age group compared to non-smokers (odds ratio [OR]: 2.29; 95% confidence interval [CI]: 1.10 to 4.76). However, the interaction between smoking and alcohol consumption was only significant among females (P < 0.05). There was a dose-dependent relationship between drinking frequency and smoking on periodontitis prevalence. In the smoking population, occasional drinking (OR: 1.70; 95% CI: 1.22 to 2.37) and regular drinking (OR: 2.28; 95% CI: 1.68 to 3.11) significantly increased the prevalence of periodontitis compared to individuals without these two factors.

CONCLUSION: These results suggested that there were interactive effects between smoking, drinking and depression on periodontitis risk and policies aimed at healthy behaviours and mental health may be beneficial for our oral health.

ABSTRACT

BACKGROUND: While tailored information might have the potential to motivate stroke survivors to make essential lifestyle changes and improve long-term outcomes, how this varies among different stroke populations is not yet fully understood.

METHOD: From November 2022 to May 2023, stroke survivors in the UK, who were clinically stable, participated in a community-based, descriptive cross-sectional study. Participants rated several information themes on a Likert scale from one to five, indicating the relevance of each information group to them. Data were analysed using Wilcoxon and chi-squared tests on SPSS. Descriptive statistics were employed for examining the preferred information delivery method, timing, personnel, and frequency.

RESULTS: Seventy survivors, with an average age of 67 ± 19 (61% males), were recruited. Survivors emphasised the importance of symptoms, risk factors, and recovery information during hospital stay, while medication and lifestyle change information were more significant in the community. Subgroup analysis revealed distinct patterns: First-time stroke survivors highlighted the importance of social and financial support (acute phase median Likert score 3, chronic phase median Likert score 4; p < 0.01), while those with prior strokes emphasised information on driving and working after stroke (acute phase median Likert score 4, chronic phase median Likert score 3; p < 0.05). Survivors recruited after six months of stroke prioritised knowledge of carer support in the community (acute phase median Likert score 3.5, chronic phase median Likert score 4; p < 0.01).

CONCLUSION: Survivors’ information needs differ depending on factors such as the recovery phase, type of stroke, time since diagnosis, and the presence of a previous stroke. Considering these factors is essential when developing or providing information to stroke survivors.
