Background: The prevalence of diabetes mellitus and early-onset dementia (EOD), defined as dementia diagnosed at an age <65 years, is increasing worldwide, with significant socioeconomic implications. We investigated the association between diabetes, prediabetes, and EOD, focusing on the influence of diabetes duration on EOD risk. Methods: Using the Korean National Health Insurance Service database, we analyzed data from 1,979,509 patients aged 40–60 years who underwent health checkups in 2009. Patients were categorized into five groups: normal, impaired fasting glucose (IFG), newly diagnosed diabetes, diabetes duration <5 years, and diabetes duration ≥5 years. Cox proportional hazard models were used to estimate the adjusted hazard ratios (aHRs) for EOD after adjusting for demographic and clinical covariates. Results: During the observation period (mean 7.75 years), 8,921 patients with EOD were identified. The diabetes group demonstrated a significantly higher incidence of EOD compared to the normal group (aHR, 1.334; 95% confidence interval [CI], 1.226 to 1.451). EOD risk increased with longer diabetes duration, with the highest risk observed in patients with diabetes ≥5 years (aHR, 1.543; 95% CI, 1.368 to 1.741). No significant difference was observed between the IFG and normal groups (aHR, 0.989; 95% CI, 0.938 to 1.043). Additionally, the hypertension group exhibited a significantly higher incidence of EOD compared to the non-hypertension group (aHR, 1.364; 95% CI, 1.291 to 1.442). Conclusion Diabetes is independently associated with increased risk of EOD, and this risk increases with longer diabetes duration. This association remained significant regardless of the presence and duration of hypertension.

As many countries implement different programs aimed at eliminating malaria, attention should be given to asymptomatic carriers that may interrupt the progress. This was a community-based cross-sectional study conducted in Tanzania from December 2022 to July 2023 within 4 villages from each of the 3 regions, Geita and Kigoma, which are high malaria transmission, and Arusha, which is low transmission. Malaria was diagnosed in asymptomatic individuals aged 1 year and older using the malaria rapid diagnostic test and light microscope. A total of 2,365 of 3,489 (67.9%) participants were enrolled from high-transmission villages. The overall prevalence was 25.5% and 15.8% by malaria rapid diagnostic test and light microscope, respectively. Using the respective tools, the prevalence was significantly higher at 35.6% (confidence interval (CI)=23.6–49.9) and 23.1% (CI=16.2–35.1) in the high-transmission regions (Geita and Kigoma) compared with 2.9% (CI=1.1–3.5) and 1.1% (CI=0.7–1.8) in the low-transmission region (Arusha). Children younger than 15 years and males accounted for the greatest proportion of infections. In the study area, the prevalence of asymptomatic cases was higher than that of reported symptomatic cases in health facilities. We hypothesize that these parasite reservoirs may contribute to the persistence of malaria in the country. Therefore, to achieve comprehensive malaria control in the country, the surveillance and screening of asymptomatic malaria cases are vital.

Background: To investigate the impact of alcohol consumption on all-cause and cancer mortalities in patients with type 2 diabetes (T2D). Methods: This nationwide cohort study included Korean patients with T2D aged >20 years from a national health exams cohort (2009 to 2012). Participants were categorized based on alcohol consumption: non, mild (<30 g/day), and heavy drinkers (≥30 g/day). Primary outcomes were all-cause and cancer mortality rates. Cox proportional hazard regression analyses were used to calculate adjusted hazard ratios (aHRs) with a 95% confidence interval (CI) with adjustments for age, sex, body mass index, smoking, exercise, comorbidities, diabetes duration, and medications. Results: Among 2,642,359 participants (median follow-up, 7.8 years), 57.2%, 32.7%, and 10.1% were non, mild, and heavy drinkers, respectively. Compared to non-drinkers, mild alcohol consumption was associated with reduced all-cause mortality (aHR, 0.81; 95% CI, 0.80 to 0.82) and cancer mortality (aHR, 0.88; 95% CI, 0.86 to 0.89), while heavy drinking increased both all-cause (aHR, 1.06; 95% CI, 1.04 to 1.07) and cancer mortalities (aHR, 1.09; 95% CI, 1.06 to 1.11). Subgroup analyses revealed variations: in chronic kidney disease and older age groups, heavy drinkers showed lower risk of all-cause mortality compared to non-drinkers. Regarding cancer mortality, younger and middle-aged groups showed protective effects of alcohol even for heavy drinkers, while females showed linear association between alcohol consumption and cancer mortality. Conclusion This study indicates a J-shaped relationship between alcohol consumption and all-cause and cancer mortality risk in patients with T2D, with variations across subgroups. These findings suggest the need for personalized recommendations considering individual risk factors.

As the number of anterior cruciate ligament (ACL) reconstructions has increased significantly, surgical techniques have also made a lot of progress, and clinical outcomes are improving accordingly. However, the authors still have different opinions on ACL anatomy, femoral tunnel position, how to make a femoral tunnel, and graft selection, and many parts are controversial. Major factors contributing to the failure of ACL reconstruction, such as technical errors and biological healing failures. To reduce technical errors, a comprehensive understanding of ACL anatomy and the ability to create a well-positioned femoral tunnel are crucial. This involves recognizing the advantages and disadvantages of three surgical techniques: modified transtibial, transanteromedial portal, and outside-in. To improve biological healing, the four principles of tissue engineering (cells, growth factors, scaffolds, and mechanical stimuli) have been increasingly explored in various methods of bioaugmentation. Residual rotational instability of the knee joint remains a significant concern. Since the rediscovery of the anterolateral ligament (ALL) in the knee joint, the role of anterolateral complex, including the ALL and the deep iliotibial band, as secondary stabilizers of anterolateral rotatory instability, has gained attention. In the quest to reinforce the anterolateral complex, there are two approaches: ALL reconstruction as anatomical reconstruction concept and lateral extraarticular tenodesis as a nonanatomical reinforcement concept.

Background: Orthotopic liver transplantation is the only option for patients with end-stage liver disease and hepatocellular carcinoma. Post-transplant immunosuppressive therapy is important to prevent graft failure. We investigated the effectiveness of tacrolimus (FK506) and their mechanisms for liver transplant immune tolerance in an outbred rat LT model. Results: To investigate the therapeutic effect of the FK506 on outbred rat LT model, FK506 and postoperative therapy were administered subcutaneously once or twice daily to transplanted rats. Histopathological and immunohistochemical analyses were conducted for all groups. The regulation of inflammatory cytokine signaling in the spleen was analyzed by flow cytometry. FK506 attenuated allograft rejection and increased survival in rat orthotopic liver transplantation models. The FK506-treated group had reduced serum levels of alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase. Furthermore, FK506 decreased the expression of inflammatory cytokines and the activation of pathogenic Th1 and Th17 cells in the liver. Conclusions Taken together, we revealed that FK506 ameliorated strong allograft rejection in outbred liver transplantation model by anti-inflammatory effect and inhibitory peroperty of pathogenic T cells.

Background: Exercise capacity is known to be an independent predictor of cardiovascular events and mortality. However, most previous studies were based on Western populations.Further study is warranted for Asian patients according to ethnic or national standards. We aimed to compare prognostic values of Korean and Western nomograms for exercise capacity in Korean patients with cardiovascular disease (CVD). Methods: In this retrospective cohort study, we enrolled 1,178 patients (62 ± 11 years;78% male) between June 2015 and May 2020, who were referred for cardiopulmonary exercise testing in our cardiac rehabilitation program. The median follow-up period was 1.6 years. Exercise capacity was measured in metabolic equivalents by direct gas exchange method during the treadmill test. The nomogram for exercise capacity from healthy Korean individuals and a previous landmark Western study was used to determine the percentage of predicted exercise capacity. The primary endpoint was the composite of major adverse cardiovascular events (MACE; all-cause death, myocardial infarction, repeat revascularization, stroke and hospitalization for heart failure). Results: A multivariate analysis showed that the risk of primary endpoint was more than double (hazard ratio [HR], 2.20; 95% confidence interval [CI], 1.10–4.40) in the patients with lower exercise capacity (< 85% of predicted) by Korean nomogram. The lower exercise capacity was one of the strong independent predictors along with left ventricular ejection fraction, age, and level of hemoglobin. However, the lower exercise capacity by Western nomogram could not predict the primary endpoint (HR, 1.33; 95% CI, 0.85–2.10). Conclusion Korean patients with CVD with lower exercise capacity have higher risk of MACE.Considering inter-ethnic differences in cardiorespiratory fitness, the Korean nomogram provides more suitable reference values than the Western nomogram to determine lower exercise capacity and predict cardiovascular events in Korean patients with CVD.
