ABSTRACT

Cerebral infarction (CI) is a common cerebrovascular disease worldwide, and the burden caused by the sequelae of CI has increased significantly. However, current treatment guidelines lack standardized recommendations for pharmacotherapy of sequelae of CI. This retrospective study collected and analyzed 1.98 million prescriptions concerning sequelae of CI from patients admitted to Zhiyun Health Internet Hospital in 2022. The mean age of patients was 66.2 ± 11.4 years, and 52.40% were male. 79.73% had one or more comorbidities. For treatment, the prescriptions of 1-, 2- and ≥ 3-drug accounted for 64.55%, 23.77% and 11.68% respectively. Chinese patent medicine (CPM) prescriptions, western medicine (WM) prescriptions, and CPM and WM combined (CPM + WM) prescriptions accounted for 53.81%, 27.33%, and 18.86% respectively. In CPM prescriptions, the most frequently prescribed medications were Salvia miltiorrhiza (34.81%), Ginkgo biloba (24.96%), Panax notoginseng (20.67%), Gastrodia (7.15%) and Ligusticum Wallichii (4.90%). For WM prescriptions, the most commonly prescribed agents were anti-hypertensive (32.82%), anti-thrombotic (16.06%), vasodilator (15.70%), anti-dementia (10.88%), and lipid-lowering (9.58%) drugs. Among CPM + WM prescriptions, 72.61% had CPM/WM = 1, 21.20% had CPM/WM < 1, and 6.19% had CPM/WM > 1. This research utilized real-world data extracted from internet hospitals in China to present valuable evidence of online prescription patterns among patients experiencing sequelae of CI.

ABSTRACT

BACKGROUND: The implementation of Enhanced Recovery After Surgery (ERAS) protocols has resulted in improved postoperative outcomes in colorectal cancer surgery. The evidence regarding feasibility and impact on outcomes in surgery for inflammatory bowel disease (IBD) is limited.

METHODS: We performed a retrospective observational cohort study, comparing patient trajectories before and after implementing an IBD-specific ERAS protocol at Zealand University Hospital. We assessed the occurrence of serious postoperative complications of Clavien-Dindo grade 3 or higher as our primary outcome, with postoperative length of stay in days and rate of readmissions as secondary outcomes, using χ², Mann-Whitney test, and odds ratios adjusted for sex and age.

RESULTS: From 2017 to 2023, 394 patients were operated on for IBD and included in our study. In the ERAS cohort, 39/250 patients experienced a postoperative complication of Clavien-Dindo grade 3 or higher compared to 27/144 patients in the non-ERAS cohort (15.6% vs. 18.8%, p = 0.420) with an adjusted odds ratio of 0.73 (95% CI 0.42-1.28). There was a significantly shorter postoperative length of stay (median 4 vs. 6 days, p < 0.001) in the ERAS cohort compared to the non-ERAS cohort. Readmission rates remained similar (22.4% vs. 16.0%, p = 0.125).

CONCLUSIONS: ERAS in IBD surgery was associated with faster patient recovery, but without an impact on the occurrence of serious postoperative complications and rate of readmissions.

ABSTRACT

Persons who contract COVID-19 are at risk of developing post-acute sequelae of SARS-CoV-2 (PASC). The objective of this study was to describe the incidence of PASC in a pediatric Medicaid population. Using a retrospective cohort of children enrolled in New York State Medicaid Managed Care we compared incident diagnoses between children with a positive laboratory test for SARS-CoV-2 in 2021 to children without a positive test in 2021 and children with a viral respiratory diagnosis in 2019. Logistic regression models estimated adjusted odds ratios using the Cohen’s d statistic to assess the strength of associations. Most unadjusted incidence of clinical outcomes were less than 1% for all cohorts. Relative to the 2021 comparison cohort, significant increases among SARS-CoV-2 cases were observed in sequela of infectious disease conditions, general signs and symptoms, and pericarditis and pericardial disease and for the 2019 comparison, sequela of infectious disease conditions and suicidal ideation. However, associations were mostly determined to be weak or marginal. In this low socioeconomic status pediatric population, incidence of new clinical sequelae was low with mostly weak or marginal increases associated with SARS-CoV-2 infection. Though the incidence was low, some outcomes may be severe. Observed associations may have been impacted by pandemic behavior modification including social distancing policies.

ABSTRACT

The homogeneity hypothesis is a common assumption in classic measurement. However, the item response theory model assumes that different respondents with same ability have the same option probabilities, which may not hold. The aim of this study is to propose a new individual random effect model that accounts for the differences in option probabilities among respondents with same latent traits by using within-person variance. The performance of the new model is evaluated through simulation studies and real data using the PRESUPP scale of PISA. The model parameters are estimated by the MCMC method. The results show that the individual random effect model can provide more accurate parameter estimates and obtain a scale parameter to describe the distribution of respondents’ abilities, under different within-person variances. The new model has lower RMSE and better model fit than the classic IRT model.

ABSTRACT

DATA SOURCES: Three electronic databases (Pubmed, Embase and the Cochrane Library) were searched in December 2022, and again for additional literature on 3-5th January 2023. Reference lists of relevant systematic reviews were hand searched for other eligible studies for inclusion.

STUDY SELECTION: Randomised controlled clinical trials and controlled clinical trials conducted on children (aged ≤ 18 years), conducted between 1974-2022 and available in English, were eligible for inclusion. Studies were excluded if caries was not an outcome, the control group was not sufficient, they were lab-based studies or studies where xylitol delivery was not a sweet or chewing gum and where the xylitol product contained a component such as fluoride which may influence the outcomes.

DATA EXTRACTION AND SYNTHESIS: Four calibrated reviewers independently screened titles and abstracts, and disagreements were resolved via group discussion. Preventative effect was determined by comparing the mean caries increment in the control and intervention groups, producing a preventative fraction. A total of 617 titles were initially screened for relevance. After duplicate removal, 268 abstracts were screened and 16 full text articles reviewed, with one more study then excluded. 10 studies investigated xylitol-containing chewing gum, and six looked at xylitol candy (one did both). Eight included studies were randomised controlled trials. Data extraction was undertaken by two reviewers.

RESULTS: 3466 participants were included in the 10 studies that investigated xylitol chewing gum, and all 10 studies reported a statistically significant preventive effect compared to a no chewing gum or placebo control. In 9 studies, the preventive fraction was clinically significant. The six studies investigating xylitol candies contained a total of 1023 participants, and only one study demonstrated a significant preventative effect.

CONCLUSIONS: There is some evidence that incorporating xylitol chewing gum daily has a caries-reducing effect in those with a moderate-to-high baseline caries level. This effect was not present for xylitol sweets.

ABSTRACT

OBJECTIVE: A systematic review and meta-analysis of the literature was carried out assessing the success rate of root canal retreatment using gutta percha.

DATA SOURCES: Four of the largest databases were used to identify existing literature with no date or language restrictions. PubMed, Cochrane, ScienceDirect, Scopus and other additional sources were searched. Grey literature was also reviewed.

STUDY SELECTION: Two authors, with Master’s degrees in endodontics and with extensive university teaching experience, were selected to screen the databases to identify suitable studies. In case the authors were not able to agree during the study selection process, a third investigator was consulted. Specific inclusion and exclusion criteria were outlined and adhered to in the study selection. Two randomised controlled trials, seven single arm prospective studies and one single arm ambispective study published before the 10th of December 2022 were included. These studies evaluated the success of root canal re-treatment, obturated with gutta percha with at least a 1-year follow-up. Nine of the studies were published between 1998 and 2022. Seven studies were conducted in Europe, one in North America and one in Asia.

DATA EXTRACTION AND SYNTHESIS: Standard Cochrane methods to assess interval validity were used. Risk of bias in individual studies was assessed using The Newcastle-Ottawa quality assessment scale (NOS) for single-arm studies, and the Cochrane risk of bias tool (RoB2) was used for randomised controlled trials. Outcome measures were standardised as either success or failure of root canal retreatment. Success was classified into 2 different criteria: Strict criteria = absence of clinical signs and symptoms and radiographically normal periodontal ligament space; and Loose criteria = absence of clinical signs and symptoms and absence or reduction of apical radiolucency in the control radiograph. Statistical analysis was undertaken using R software and the Freeman-Turkey transformation was performed. Results were visualised using forest plots. Heterogeneity between studies was measured using the Cochrane Q test and I² values.

RESULTS: Whilst following strict criteria, the success rate of non-surgical root canal retreatment obturated with gutta percha was 71% for 1-3 years follow-up (95% CI, 0.66-0.77) and 77% for 4-5 years follow-up (95% CI, 0.67-0.86). Heterogeneity was moderate (I² = 61.4) and low (I² = 0.0), respectively. Factors reducing the success rate of root canal re-retreatment under the strict criteria were older patients, mandibular teeth, molar teeth, the presence of a peri-apical radiolucency, teeth with a previous radiolucency, large peri-apical radiolucency’s, higher initial periapical index scores and multiple visit-retreatments. Following the loose criteria, the success rate of non-surgical root canal re-treatment obturated with gutta percha was 87% for 1-3 years follow-up (95% CI, 0.79-0.93) with significant heterogeneity across the studies (I² = 88.5%). Factors influencing the success rate under the loose criteria were large periapical lesions >5 mm and higher initial periapical index (PAI) scores.

CONCLUSIONS: Non-surgical root canal retreatment results in favourable outcomes. However, there are several factors which can result in a lower success rate: the presence and size of a periapical radiolucency, a higher initial PAI score, multiple-visit retreatments, and the size and position of the tooth.

ABSTRACT

STUDY OBJECTIVES: To investigate the cost-effectiveness of cognitive behavioral therapy for insomnia (CBTI), with an additional focus on digital cognitive behavioral therapy for insomnia (dCBTI) in adults with insomnia.

METHODS: We searched eight electronic databases for economic evaluations of CBTI: PubMed, Scopus, Web of Science, psycINFO, Cochrane, Library, CINAHL, ProQuest and National Health Service Economic Evaluation Database. Meta-analyses were performed to investigate the effects and costs between CBTI and control groups (no treatment, other treatments included hygiene education and treatment as usual). Subgroup analyses for dCBTI were conducted.

RESULTS: Twelve randomized controlled trails studies between 2004 and 2023 were included in our systematic review and meta-analyses. The incremental cost-utility ratios and incremental cost-effectiveness ratios showed that the CBTI and dCBTI groups were more cost-effective than controls, from healthcare perspective and societal perspective, respectively. Compared to controls, CBTI demonstrated significantly better efficacy within 12 months. Healthcare costs were significantly higher in the CBTI groups compared to the controls within 6 months but there was no difference at 12 months. Additionally, dCBTI was associated with significantly lower presenteeism costs compared to controls at 6 months.

CONCLUSIONS: Our findings suggest that CBTI is more cost-effective than other treatments or no treatment for adults with insomnia. It may bring more economic benefits in the long-term, especially in long-lasting efficacy and costs reduction. In addition, dCBTI is one of the cost-effective options for insomnia.

ABSTRACT

Pediatric burns pose a significant health burden in LMICs. Despite efforts to address burn prevention and management, morbidity and mortality rates remain high, particularly among children. Understanding pediatric burn epidemiology and predictors of clinical outcomes is crucial for developing effective prevention strategies and improving patient-care. This retrospective cohort study analyzed pediatric burn patients admitted to a tertiary burn-center in India, between March-2022 and December-2023. Demographic date, burn characteristics, treatments, complications and outcomes were collected. Statistical analysis, including logistic and linear regression, was conducted to identify predictors of mortality, sepsis, and hospital stay length. Among 332 pediatric burn patients, median age was 3 years, with a male predominance. Scald burns were the most common, followed by electrical and flame burns. Median total body surface area burned was 20%, with upper and lower extremities most affected. The incidence of electrical burns increased with age and was associated with a longer length of stay. Mortality rate was 14.2%, with age >10 years, male gender, and TBSA >30% predicting mortality. Complications like sepsis significantly increased mortality risk, while deep burns were associated with longer hospital stays. This study underscores importance of targeted prevention efforts and specialized care. Scald burns among young children highlight the need for safer cooking practices, while the high incidence of electrical burns in older children suggests age-specific education interventions are necessary. Predictors of mortality identified can guide risk assessment and resource allocation, emphasizing the importance of infection control and wound management strategies in improving outcomes.

ABSTRACT

BACKGROUND AND PURPOSE: Transcranial Doppler (TCD) identifies acute stroke patients with arterial occlusion where treatment may not effectively open the blocked vessel. This study aimed to examine the clinical utility and prognostic value of TCD flow findings in patients enrolled in a multicenter prospective study (CLOTBUST-PRO).

METHODS: Patients enrolled with intracranial occlusion on computed tomography angiography (CTA) who underwent urgent TCD evaluation before intravenous thrombolysis was included in this analysis. TCD findings were assessed using the mean flow velocity (MFV) ratio, comparing the reciprocal ratios of the middle cerebral artery (MCA) depths bilaterally (affected MCA-to-contralateral MCA MFV [aMCA/cMCA MFV ratio]).

RESULTS: A total of 222 patients with intracranial occlusion on CTA were included in the study (mean age: 64 ± 14 years, 62% men). Eighty-eight patients had M1 MCA occlusions; baseline mean National Institutes of Health Stroke Scale (NIHSS) score was 16, and a 24-hour mean NIHSS score was 10 points. An aMCA/cMCA MFV ratio of <.6 had a sensitivity of 99%, specificity of 16%, positive predictive value (PV) of 60%, and negative PV of 94% for identifying large vessel occlusion (LVO) including M1 MCA, terminal internal carotid artery, or tandem ICA/MCA. Thrombolysis in Brain Ischemia scale, with (grade ≥1) compared to without flow (grade 0), showed a sensitivity of 17.1%, specificity of 86.9%, positive PV of 62%, and negative PV of 46% for identifying LVO.

CONCLUSIONS: TCD is a valuable modality for evaluating arterial circulation in acute ischemic stroke patients, demonstrating significant potential as a screening tool for intravenous/intra-arterial lysis protocols.

ABSTRACT

OBJECTIVES: Pre-doctoral dental programs must provide opportunities for students to become proficient in self-assessment, communication skills, health literacy, and cultural competence, essential for independent unsupervised practice. This study aimed to assess how student learning through a classroom education service-learning program addresses the Commission on Dental Accreditation (CODA) standards 2-11 and 2-17; specifically through the examination of self-assessment, communication skills, health literacy, and cultural competence.

METHODS: This 2022 retrospective mixed methods cohort study examined unstructured faculty comments on drafted lesson plans and structured evaluations of classroom education service-learning rehearsal sessions. A random sample of faculty comments from three academic years, 2018, 2019, and 2020, were deidentified and analyzed by five researchers for emerging themes using NVivo. Quantitative data from rehearsal presentations were analyzed with descriptive statistics to assess the concordance of self and faculty feedback on specific evaluation criteria.

RESULTS: Six major themes from faculty lesson plan feedback emerged: knowledge, professionalism, communication, presentation skills, cultural competence, and program logistics. Concordance between faculty feedback and student self-assessment ranged from 83% to 92.4% across all evaluation criteria over the 3 years: spoke clearly and confidently at the right pace, provided accurate dental terminology and facts, used grade-appropriate language, provided clear instructions to follow, appeared enthusiastic throughout the rehearsal presentation, and designed a well thought out lesson plan that will engage children for the entire presentation.

CONCLUSION: Findings support the classroom education service-learning program as a framework to provide opportunities for student self-assessment and feedback on communication skills, health literacy, and cultural competence aligned with CODA standards 2-11 and 2-17.
