BACKGROUND:Taxes on sugar-sweetened beverages can improve public health. We aimed to characterise the extent and types of sugar-sweetened beverage taxes implemented worldwide and the national characteristics predicting implementation, such as sugar-sweetened beverage intake amounts, disease rates, or economic development. METHODS:This longitudinal analysis aggregated serial global datasets (including the Global Dietary Database, Non-Communicable Diseases Risk Factor Collaboration, Global Burden of Disease study, and World Bank data) from 1990 to 2024 in 183 countries to assess sugar-sweetened beverage tax characteristics and national predictors of policy adoption. Sugar-sweetened beverage taxes for public health purposes were identified and characterised, including amounts, fiscal instruments, structures, and covered beverages. Sugar-sweetened beverage consumption, obesity and diabetes prevalence, gross domestic product (GDP), and sociodemographic index (SDI) were assessed as predictors of tax implementation using Cox proportional hazards models with time-varying covariates. FINDINGS/RESULTS:From 1990 to 2024, 64 countries implemented sugar-sweetened beverage taxes, accelerating over time and covering 3·5 billion people globally. South Asia led in adoption (50% of countries; median tax rate 7·5%), followed by southeast and east Asia (47·8%; 5·0%), the Middle East and North Africa (30·0%; 17·0%), and Latin America and the Caribbean (31·3%; 7·0%). Taxes were ad valorem (ie, based on price; 45%), volume-based (44%), sugar-content-based (5%), or mixed (6%), and 13% of countries earmarked revenue for public health. Multivariable-adjusted predictors of tax implementation included diabetes prevalence (hazard ratio [HR]=1·22 [95% CI 1·05-1·43]), obesity prevalence (1·14 [1·00-1·29]), GDP per capita (HR per $10 000: 1·19 [1·06-1·34]), and SDI (0·70 [0·57-0·86]), but not sugar-sweetened beverage intake (0·77 [0·42-1·39]). INTERPRETATION/CONCLUSIONS:Global adoption of sugar-sweetened beverage taxes has rapidly accelerated since 1990; however, there is important heterogeneity by region and tax structure, and the taxes are shaped by a country's economic capacity, social development, and health conditions. FUNDING/BACKGROUND:This work was supported by the National Institutes of Health (R01HL115189).

BACKGROUND:Early detection of oral potentially malignant disorders (OPMDs) and oral cavity cancer can improve patient prognosis. In this guideline, the authors address the use of vital staining, specifically toluidine blue, as an adjunct to screen adults without mucosal abnormalities and to determine the need for biopsy among adults with mucosal abnormalities in the oral cavity. TYPES OF STUDIES REVIEWED/METHODS:The authors conducted systematic searches to identify evidence on the benefits and harms of using vital staining as an adjunct as well as patient and clinician values and preferences regarding the use of this adjunct. The guideline panel used the Grading of Recommendations Assessment, Development and Evaluation Evidence to Decision framework to formulate recommendations. As part of the framework, the panel also considered the resources required, equity, acceptability, and feasibility when formulating recommendations. RESULTS:The panel formulated 2 recommendations and 2 good practice statements. For adults with and without mucosal abnormalities, the panel recommend against the use of vital staining as an adjunct (conditional recommendation, very low certainty). The good practice statements encourage clinicians to perform a clinical oral examination in all adult patients. CONCLUSIONS AND PRACTICAL IMPLICATIONS/CONCLUSIONS:Biopsy remains the first choice for obtaining a definitive diagnosis of an OPMD and oral squamous cell carcinoma. Clinical oral examination should be performed in all asymptomatic adults with no clinically evident mucosal abnormality. When implementing or adapting these recommendations, local contexts should be taken into account to ensure equitable access to early detection.

BACKGROUND:Identifying oral potentially malignant disorders and oral cavity cancer early can lead to better patient outcomes. The guideline panel evaluated the usefulness of light-based adjuncts for screening adults without mucosal abnormalities and for determining the need for biopsy among adults with mucosal abnormalities in the oral cavity or on the lip. TYPES OF STUDIES REVIEWED/METHODS:The authors conducted a living systematic review to evaluate evidence on the benefits and harms of light-based adjuncts and a scoping review to assess people and clinician values and preferences regarding the use of light-based adjuncts and biopsy of mucosal abnormalities. The guideline panel used this evidence to formulate recommendations according to the Grading of Recommendations Assessment, Development and Evaluation Evidence to Decision framework. The framework also guided the panel's consideration of required resources, equity, acceptability, and feasibility in shaping the final recommendations. RESULTS:The guideline panel formulated 2 recommendations and 2 good practice statements. For adults with and without mucosal abnormalities, they formulated conditional recommendations against the use of light-based adjuncts on the basis of very low certainty evidence. The good practice statements urge clinicians to perform a clinical oral examination in all adult patients. CONCLUSIONS AND PRACTICAL IMPLICATIONS/CONCLUSIONS:Biopsy remains the reference standard for establishing a definitive diagnosis of an oral potentially malignant disorder and oral squamous cell carcinoma. All adults should undergo a clinical oral examination in primary care settings. When implementing or adapting these recommendations, local contexts should be considered to promote equitable access to early detection.

PURPOSE/OBJECTIVE:Evidence-based dentistry has progressed from case reports and series to best evidence consensus statements; to non-randomized and randomized controlled studies; to systematic reviews (SRs), which analyze individual studies; and to umbrella reviews (URs), which now evaluate SRs. The purpose of this article is to review and summarize the findings of recent dental URs selected by the authors because they analyzed the quality of SRs, identified their strengths and weaknesses, and represented multiple disciplines of dentistry and diverse journals. MATERIALS AND METHODS/METHODS:A PubMed search was completed using the keywords "umbrella review, dentistry" and the filters "meta-analysis" and "systematic review" along with the years 2022-2024. There were 93 URs listed, with 56 being dental-related. The 56 URs were reviewed, and 15 were collectively selected by the authors to be summarized as examples of multiple dental disciplines and dental-related treatments published in a diverse group of dental journals. RESULTS:The 15 selected URs exhibited similar formats with findings based on the included SRs. The results of the 15 URs are summarized and presented along with the strengths and weaknesses noted in the SRs. CONCLUSIONS:The URs included in this article assessed the quality of SRs based on AMSTAR 2 (AMSTAR 2 is a critical appraisal tool used to assess the methodological quality of systematic reviews, particularly those focusing on healthcare interventions), ROBIS (ROBIS is the first rigorously developed tool designed specifically to assess the risk of bias in systematic reviews), and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Deficiencies were reported relative to the following items: failure to register the protocol before starting the review; incomplete literature search; absence of a list of excluded studies and lack of justification for the exclusions; inadequate review methods; lack of reporting the sources of funding; failing to assess risk of bias (ROB) or an unsatisfactory technique to assess ROB; not listing potential sources of conflict of interest; and lack of homogeneity in the study design, which prevented performing a meta-analysis. These findings indicate the need for careful study of SR and UR guidelines related to design and review, assessment of bias risk, and review reporting before applying the conclusion to clinical practice. Clinicians need to be aware of the deficiencies present in SRs and URs. Also, it is important to recognize that reviews are based on only those studies that met the inclusion criteria of the authors, and the exclusion of studies is fraught with potential bias.

Existence of linguistic, gender and ethno-racial differences in patients with sepsis remains relatively unknown, especially in the public health domain. Retrospective analysis of data reported by a hospital in South Brooklyn to a New York State sepsis registry was undertaken over a 24-month period. Inclusion criteria were age over 18, available linguistic, gender and ethno-racial data, and registration in the New York State sepsis registry. Patients with missing data fields were excluded from the study. Primary outcome was the correlation of gender, race, ethnic & language-based differences with overall sepsis-based mortality. Secondary outcomes were the correlation of the same demographic variables with rates of mechanical ventilation, vasopressor use, intensive care unit (ICU) admission rates & overall incidence of sepsis and septic shock. Results: 677 patients were included in the final analysis in this single center retrospective observational cohort study and multiple statistically significant primary and secondary outcomes were found. Non-English-speaking patients had a higher incidence rate of sepsis-based mortality when compared to their English-speaking cohorts. The incidence rate difference is -0.36 (95% CI -0.49 to -0.22), with a P-value < 0.0001. A higher rate of vasopressor use was noted among non-English speaking patients when compared to their English speaking counterparts. The difference in incidence rates was -0.35, (95% CI -0.46 to -0.25) with a P-value of < 0.0001. Non-English-speaking patients had a higher incidence of receiving mechanical ventilation when compared to English-speaking cohorts. The incidence rate difference is -0.35 (95% CI -0.48 to -0.22), with a P-value < 0.0001. Non-English-speaking patients had a higher ICU admission rate with an incidence rate difference of -0.30, at a P value < 0.0001. Non-English-speaking patients had a higher sepsis incidence rate (0.70, 95% CI 0.63 to 0.78) compared to English-speaking patients (0.30, 95% CI 0.25 to 0.36), with a P-value of < 0.0001. Non-English-speaking patients experienced a higher incidence of septic shock (0.70, 95% CI 0.63 to 0.78) compared to English-speaking patients (0.30, 95% CI 0.25 to 0.36), with a P-value of < 0.0001. Caucasians showed statistically significant and higher rates across all primary and secondary outcomes albeit with greater statistical fragility. No significant differences were noted with regards to the impact of gender on all outcomes. Conclusion: Significant and multiple linguistic and ethno-racial differences were noted in this single center study with regards to sepsis-based morbidity and mortality outcomes. These differences need to be validated in larger, multi-center trials and could inform future efforts focused on identifying higher risk subsets in patients presenting with sepsis and septic shock in a public health setting.

BackgroundPostoperative care following endoscopic sinus surgery (ESS) aims to optimize mucosal healing, reduce inflammation, and minimize infectious complications. Although saline irrigation is considered standard of care, the potential benefit of adding topical antibiotics, such as mupirocin, during the early postoperative period remains uncertain.ObjectiveTo evaluate whether short-term postoperative mupirocin nasal irrigation improves clinical, endoscopic, and microbiological outcomes compared with saline irrigation alone following ESS.MethodsThis prospective, randomized, double-blinded, placebo-controlled trial included adults with chronic rhinosinusitis undergoing ESS. Patients were randomized to receive either mupirocin (0.05%) nasal irrigation or placebo saline irrigation twice daily for 21 days postoperatively. Outcomes assessed within the first 3 months included patient-reported symptoms using the sinonasal outcomes test (SNOT-22) and visual analog scale (VAS), endoscopic findings (mucosal edema, polyp formation, crusting, granulation tissue, and purulence), postoperative sinus culture results, and need for systemic antibiotics.ResultsSixty-eight patients were enrolled, and 56 completed follow-up. Both groups demonstrated significant postoperative improvement in SNOT-22 and VAS scores compared with preoperative baseline, without significant between-group differences. However, the mupirocin group showed significantly lower rates of endoscopic mucosal edema and polyp formation at 1 month postoperatively. Negative postoperative cultures were also more frequent in the mupirocin group, with reduced need for systemic oral antibiotics. No significant differences were observed in crusting, granulation tissue, purulence, steroid use, or pain medication requirements.ConclusionShort-term prophylactic postoperative mupirocin nasal irrigation after ESS does not confer additional improvement in patient-reported quality-of-life outcomes compared with saline alone but appears to reduce early inflammatory endoscopic changes, bacterial culture positivity, and need for systemic antibiotics. Larger studies with longer follow-up are needed to confirm these findings.

Localized treatment of oligometastatic liver disease can improve both local control and survival. The liver is a frequent site of metastases from colorectal, breast, and lung cancers, but most patients are not eligible for surgical resection due to lesion number, location, or comorbidities. For these patients, non-surgical ablative methods such as radiofrequency ablation (RFA) and stereotactic body radiotherapy (SBRT) and increasingly microwave ablation (MWA) are used. RFA was used as the primary comparator in this review because it represents the most historically established and widely reported ablative modality in the comparative radiotherapy literature. While RFA has been the traditional approach, SBRT is emerging as a promising alternative, offering precise, non-invasive treatment. SBRT may be especially useful for larger lesions or tumors in locations where RFA is difficult to perform. However, high-quality evidence and large-scale trials are still needed to confirm its efficacy and define its role. This review compares the strengths and limitations of both methods and provides practical guidance for clinical decision-making in the treatment of patients with inoperable liver metastases.

The Cattell-Imanaga reconstruction (CIR) is considered a more physiologic reconstruction after pancreaticoduodenectomy, as it promotes a more physiological mixing of alimentary and biliopancreatic secretions and facilitates endoscopic access to the anastomoses compared with traditional techniques. However, its application after total pancreatectomy (TP) has not previously been reported. This study describes the surgical technique and institutional experience with CIR, named modified CIR (mCIR), in patients undergoing open TP at a high-volume pancreatic surgery center. The mCIR positions the gastro-/duodeno-jejunostomy (G/DJ) proximally and the hepatico-jejunostomy (HJ) distally on a single transmesocolic limb. 89 patients underwent open TP with mCIR. Both en bloc and stepwise TP were performed; stepwise was mainly used for positive frozen margins (51.7%), high POPF risk (34.8%), or need for vascular resection to reduce POPF-related vascular complications (12.4%). Grade B-C biliary fistula occurred in 6.7% of patients, cholangitis secondary to hepatico-jejunostomy (HJ) stricture in 2.2%, delayed gastric emptying (DGE) in 11%, and duodeno-jejunostomy (DJ) leakage in 1.1%. An endoscopic interventional approach was generally preferred for the management of HJ complications. Major morbidity and 90-day mortality were 23.6% and 3.4%, respectively. The readmission rate was 9.7%, mainly due to infected or symptomatic collections. This is the first study to describe mCIR following TP and to report postoperative outcomes in line with previously reported results for traditional reconstruction techniques.

RATIONALE/BACKGROUND:Aggression is an innate social behavior prevalent across animal species. However, in modern human society, inter-personal aggression is considered disruptive and detrimental to both families and communities. Clinically, antipsychotics, which primarily target dopamine (DA) receptors, have been widely used to suppress hyper-aggression. However, the mechanisms underlying the effect of the antipsychotics remain incompletely understood. OBJECTIVES/OBJECTIVE:We reviewed key steps in brain DA synthesis and summarized genetic and pharmacological evidence supporting the role of the mesolimbic DA system in aggression. Next, we discussed recent circuit studies that elucidate the DA action in modulating aggression-related brain regions. These lines of evidence collectively suggest that DA acts on different brain regions to facilitate aggression and self-learning, and signals the valence of the fighting experience.

OBJECTIVE:ratio (TPR) imaging approach and evaluates its ability to characterize MS lesions alongside other quantitative MRI (qMRI) metrics. METHODS:and PD values were used to illustrate TPR contrast. Statistical analyses included Wilcoxon rank-sum tests and Spearman correlations (p < 0.05). RESULTS:* (92 ms) values but lower MTR (37.3%) and MTsat (1.57%) compared to hypointense lesions (1085 ms; 0.88 a.u.; 64 ms; 46%; 2.48%, respectively). QSM values varied across lesion types. INTERPRETATION/CONCLUSIONS:, PD, and MT metrics, consistent with demyelination. In contrast, hypointense lesions may reflect tissue changes associated with repair processes such as remyelination.
