An evidence map on traditional medicine across health outcomes.

Background: Traditional medicine (TM) plays a significant role in healthcare either as part of the primary healthcare system or as an adjunct to conventional medicine. This study aimed to map systematic reviews (SRs) of TM modalities across health conditions and identify gaps in the research literature to facilitate priority setting in future TM research. Methods: We searched 17 databases from January 2018 to December 2022. Reviewers in pairs independently performed the database search, screened each record for inclusion, extracted data, and performed quality assessments using the AMSTAR 2 - A Measurement Tool to Assess systematic Reviews. To be included in this evidence map, the studies had to be SRs of clinical studies that evaluated the effectiveness of a TM modalities. The included SRs were analyzed according to TM modality, ICD-11 disease classification, and health outcomes, and visualized using graphical plots. Results: We retrieved 241,509 records. After excluding duplicate records, 181,616 titles and abstracts were screened and 20,856 records were selected for full-text assessment, of which 18,137 records were further excluded. The final 2719 included SRs were primarily in adults (2591) with only 128 SRs in the pediatric population. The most commonly evaluated health conditions were diseases of the digestive system, circulatory system, and genitourinary system, with herbal medicine (n = 1867) and acupuncture (n = 471) being the most investigated TM modalities in treating these illnesses. Based on AMSTAR 2 criteria, the methodology quality of the included SRs is considerably low. Conclusion: This evidence map provides a comprehensive overview of the extent and nature of the available research onTM modalities across health conditions. It provides an initial step towards characterizing the global evidence base and outlining gaps in the existing evidence. We regard this study as laying the basis for future research of TM modalities. Registration: The protocol of this map is registered in PROSPERO (CRD42023416355).

The senescence-associated secretome of hedgehog-deficient hepatocytes drives MASLD progression.

The burden of senescent hepatocytes correlates with MASLD severity but mechanisms driving senescence, and how it exacerbates MASLD are poorly understood. Hepatocytes become senescent when Smoothened (Smo) is deleted to disrupt Hedgehog signaling. We aimed to determine if the secretomes of Smo-deficient hepatocytes perpetuate senescence to drive MASLD progression. RNA seq analysis confirmed that hepatocyte populations of MASLD livers are depleted of Smo(+) cells and enriched with senescent cells. When fed CDA-HFD, Smo(-) mice had lower antioxidant markers and developed worse DNA damage, senescence, MASH and liver fibrosis than Smo(+) mice. Sera and hepatocyte-conditioned medium from Smo(-) mice were depleted of thymidine phosphorylase (TP), a protein that maintains mitochondrial fitness. Treating Smo(-) hepatocytes with TP reduced senescence and lipotoxicity; inhibiting TP in Smo(+) hepatocytes had the opposite effects and exacerbated hepatocyte senescence, MASH, and fibrosis in CDA-HFD-fed mice. Therefore, we found that inhibiting Hedgehog signaling in hepatocytes promotes MASLD by suppressing hepatocyte production of proteins that prevent lipotoxicity and senescence.

Application Development of Baihui (GV20) Moxibustion in Ancient China: a Data Analysis Study Based on Ancient Books.

Importance: We compile and analyze ancient literature related to Baihui (GV20) moxibustion and summarize the development of its ancient clinical application. Observations: The Chinese Medical Classic (5th edition) was used as the search source to screen and organize articles related to Baihui moxibustion to establish a database. We created indexing norms according to study characteristics and indexed books, dynasties, literary styles, disease key words, matching acupoints, combinations, moxibustion amounts, and moxa cone sizes. SPSS version 24.0 software was used to calculate the index results. A total of 320 articles that met the requirements were finally included and were attributed to 99 ancient books, spanning from the Western Han Dynasty to the Qing Dynasty. A total of 45 keywords were used for disease evidence: the most frequent occurrences were internal medicine (primary category), limb meridians (secondary category), and head diseases (specific patterns). Conclusions and Relevance: Baihui moxibustion has been updated and developed in the literature over the ages, and the method of Baihui moxibustion is diverse. The main treatment rule of Baihui moxibustion considers the whole body and close treatment of partial diseases. Baihui moxibustion also has the rule of following meridian indications, with treatment based on syndrome differentiation and compatible application. Baihui moxibustion alone has a relatively strong effect of raising yang and lifting the sunken, which can treat the sinking of qi and deficiency.

A Compound Containing Aldehyde Dehydrogenase Relieves the Effects of Alcohol Consumption and Hangover Symptoms in Healthy Men: An Open-Labeled Comparative Study.

This open-labeled and comparative study aimed to test the efficacy and safety of a fermented rice extract-based substance containing yeast-fermented powder having aldehyde dehydrogenase (KisLip®, Pico Entech, Republic of Korea) in healthy male individuals. Healthy male subjects (n = 20) consumed 90 g of alcohol at their first visit. At the second visit, participants consumed 90 g of alcohol or alcohol with a low dose of KISLip® (2000 mg, KL-L) and then 90 g of alcohol or alcohol with a high dose of KISLip® (3000 mg, KL-H) at the third visit. The efficacy of KISLip® depends on the mutational status of important genes related to alcohol metabolism, including alcohol dehydrogenase (ADH1B), cytochrome P4502E1 (CYP2E1 (5B) and CYP2E1 (6)), and aldehyde dehydrogenase (ALDH2). KISLip® significantly reduced the highest level (Cmax) of alcohol and overall levels of acetaldehyde compared to the alcohol-only group in a dose-dependent manner. These significant effects of KISLip® on alcohol metabolism were observed independent of mutations in the four genes. In addition, hangover symptoms were significantly decreased in the KISLip® treated groups. During the study, the participants did not show any adverse events after KISLip® intake. This clinical study suggested that supplementation of KISLip® had beneficial effects on alcohol metabolism and might ameliorate the severity of hangovers without any adverse events.

The association between TSH and thyroid hormones in the normal or subclinical dysfunction range with left ventricular diastolic dysfunction.

Thyroid hormones modulate the cardiovascular system. However, the effects of subclinical thyroid dysfunction and euthyroidism on cardiac function remain unclear. We investigated the association between left ventricular (LV) diastolic dysfunction and subclinical thyroid dysfunction or thyroid hormones within the reference range. This cross-sectional study included 26,289 participants (22,197 euthyroid, 3,671 with subclinical hypothyroidism, and 421 with subclinical thyrotoxicosis) who underwent regular health check-ups in the Republic of Korea. Individuals with thyroid stimulating hormone (TSH) levels > 4.2 µIU/mL and normal free thyroxine (FT4, 0.78-1.85 ng/dL) and triiodothyronine (T3, 76-190 ng/dL) levels were defined as having subclinical hypothyroidism. Individuals with serum TSH levels < 0.4 µIU/mL and normal FT4 and T3 levels were defined as having subclinical thyrotoxicosis. The cardiac structure and function were evaluated using echocardiography. LV diastolic dysfunction with normal ejection fraction (EF) was defined as follows: EF of > 50% and (a) E/e' ratio > 15, or (b) E/e' ratio of 8-15 and left atrial volume index ≥ 34 mL/m2. Subclinical hypothyroidism was significantly associated with cardiac indices regarding LV diastolic dysfunction. The odds of having LV diastolic dysfunction was also increased in participants with subclinical hypothyroidism (adjusted odds ratio [AOR] 1.36, 95% confidence interval [CI], 1.01-1.89) compared to euthyroid participants. Subclinical thyrotoxicosis was not associated with LV diastolic dysfunction. Among the thyroid hormones, only serum T3 was significantly and inversely associated with LV diastolic dysfunction even within the normal range. Subclinical hypothyroidism was significantly associated with LV diastolic dysfunction, whereas subclinical thyrotoxicosis was not. Serum T3 is a relatively important contributor to LV diastolic dysfunction compared to TSH or FT4.

SUPERFICIAL AND DEEP VASCULAR COMPLEXES DAMAGED TO DIFFERENT EXTENTS IN ADVANCED STAGES OF DIABETIC RETINOPATHY.

PURPOSE: To identify the extent of damage to the superficial vascular complex and deep vascular complex as the stage of diabetic retinopathy (DR) increases. METHODS: Subjects were divided into four groups: patients with type 2 diabetes without DR (Group 1), those with mild-to-moderate nonproliferative DR (Group 2), those with severe-to-very severe nonproliferative DR (Group 3), and those with proliferative DR (Group 4). The vessel densities of the superficial vascular complex (superficial vessel density, SVD) and deep vascular complex (deep vessel density, DVD) and their ratios were compared. Linear regression analyses were used to identify factors associated with the SVD/DVD ratio. RESULTS: The SVDs were 25.5% ± 6.1%, 25.1% ± 7.0%, 24.5% ± 9.0%, and 21.6% ± 6.9% (P = 0.048); the DVDs 25.6% ± 5.3%, 23.0% ± 7.0%, 22.3% ± 8.8%, and 17.5% ± 5.0% (P < 0.001); and the SVD/DVD ratios 1.00 ± 0.16, 1.12 ± 0.20, 1.14 ± 0.33, and 1.24 ± 0.27 (P < 0.001) in Groups 1 to 4, respectively. In multivariate analysis, DR severity (B = 7.16, P < 0.001) and the HbA1c level (B = 1.57, P = 0.042) were significantly associated with the SVD/DVD ratio. CONCLUSION: Both the SVD and DVD tended to decrease in the advanced stages of DR, and the SVD/DVD ratio increased, indicating more severe damage to the deep vascular complex than the superficial vascular complex. The ratio was positively associated with the HbA1c level, indicating a significant relationship between that level and DVD rather than SVD damage.

Longitudinal changes in each retinal layer thickness in patients with non-ischemic central retinal vein occlusion.

BACKGROUND: To identify longitudinal changes in each retinal layer thickness in central retinal vein occlusion (CRVO) patients with resolved macular edema (ME). METHODS: In this retrospective observational study, CRVO patients without a recurrence of ME for more than 3 years and normal controls were enrolled. Each retinal layer thickness of the parafoveal area, including ganglion cell complex (GCC), inner nuclear layer (INL), outer plexiform layer (OPL), outer nuclear layer (ONL), photoreceptor layer (PRL), and retinal pigment epithelium (RPE) was measured. After the resolution of ME, three more examinations with a 1-year interval were analyzed. RESULTS: A total of 98 eyes were enrolled, 50 eyes for the control group and 48 eyes for the CRVO group. The baseline GCC thickness was 114.2 ± 15.6 µm and 104.2 ± 25.4 µm in the control and CRVO groups, respectively, which was significantly different (P = 0.022). The thicknesses of other layers including INL, OPL, ONL, PRL, and RPE were not significantly different at baseline. The reduction rate of GCC, INL, OPL, and ONL was - 3.92, - 1.33, - 0.91, and - 2.31 µm/year in the CRVO group, whereas no significant reductions were observed in the control group. Best-corrected visual acuity was significantly associated with changes in the GCC, OPL, and ONL in the CRVO group. CONCLUSIONS: In patients with CRVO, even in the absence of recurrent ME, retinal damage progresses over time, evidenced by thinning of the inner retina and outer retina including OPL and ONL. These changes may be associated with alterations in visual function.

Emission of Intermediate Volatile Organic Compounds from Animal Dung and Coal Combustion and Its Contribution to Secondary Organic Aerosol Formation in Qinghai-Tibet Plateau, China.

Intermediate volatility organic compounds (IVOCs) are important precursors to secondary organic aerosols (SOAs), but they are often neglected in studies concerning SOA formation. This study addresses the significant issue of IVOCs emissions in the Qinghai-Tibetan plateau (QTP), where solid fuels are extensively used under incomplete combustion conditions for residential heating and cooking. Our field measurement data revealed an emission factor of the total IVOCs (EFIVOCs) ranging from 1.56 ± 0.03 to 9.97 ± 3.22 g/kg from various combustion scenarios in QTP. The markedly higher EFIVOCs in QTP than in plain regions can be attributed to oxygen-deficient conditions. IVOCs were dominated by gaseous phase emissions, and the primary contributors of gaseous and particulate phase IVOCs are the unresolved complex mixture and alkanes, respectively. Total IVOCs emissions during the heating and nonheating seasons in QTP were estimated to be 31.7 ± 13.8 and 6.87 ± 0.45 Gg, respectively. The estimated SOA production resulting from combined emissions of IVOCs and VOCs is nearly five times higher than that derived from VOCs alone. Results from this study emphasized the pivotal role of IVOCs emissions in air pollution and provided a foundation for compiling emission inventories related to solid fuel combustion and developing pollution prevention strategies.

Long-term spatial distribution and implication of black and brown carbon in the Tibetan Plateau.

Black carbon (BC) and brown carbon (BrC) over the high-altitude Tibetan Plateau (TP) can significantly influence regional and global climate change as well as glacial melting. However, obtaining plateau-scale in situ observations is challenging due to its high altitude. By integrating reanalysis data with on-site measurements, the spatial distribution of BC and BrC can be accurately estimated using the random forest algorithm (RF). In our study, the on-site observations of BC and BrC were successively conducted at four sites from 2018 to 2021. Ground-level BC and BrC concentrations were then obtained at a spatial resolution of 0.25° × 0.25° for three periods (including Periods-1980, 2000, and 2020) using RF and multi-source data. The highest annual concentrations of BC (1363.9 ± 338.7 ng/m3) and BrC (372.1 ± 96.2 ng/m3) were observed during Period-2000. BC contributed a dominant proportion of carbonaceous aerosol, with concentrations 3-4 times higher than those of BrC across the three periods. The ratios of BrC to BC decreased from Period-1980 to Period-2020, indicating the increasing importance of BC over the TP. Spatial distributions of plateau-scale BC and BrC concentrations showed heightened levels in the southeastern TP, particularly during Period-2000. These findings significantly enhance our understanding of the spatio-temporal distribution of light-absorbing carbonaceous aerosol over the TP.

Aging promotes metabolic dysfunction-associated steatotic liver disease by inducing ferroptotic stress.

Susceptibility to the biological consequences of aging varies among organs and individuals. We analyzed hepatocyte transcriptomes of healthy young and aged male mice to generate an aging hepatocyte gene signature, used it to deconvolute transcriptomic data from humans and mice with metabolic dysfunction-associated liver disease, validated findings with functional studies in mice and applied the signature to transcriptomic data from other organs to determine whether aging-sensitive degenerative mechanisms are conserved. We discovered that the signature enriches in diseased livers in parallel with degeneration. It is also enriched in failing human hearts, diseased kidneys and pancreatic islets from individuals with diabetes. The signature includes genes that control ferroptosis. Aged mice develop more hepatocyte ferroptosis and liver degeneration than young mice when fed diets that induce metabolic stress. Inhibiting ferroptosis shifts the liver transcriptome of old mice toward that of young mice and reverses aging-exacerbated liver damage, identifying ferroptosis as a tractable, conserved mechanism for aging-related tissue degeneration.

Effects of interleukin-10 treated macrophages on bone marrow mesenchymal stem cells via signal transducer and activator of transcription 3 pathway.

BACKGROUND: Alveolar bone defects caused by inflammation are an urgent issue in oral implant surgery that must be solved. Regulating the various phenotypes of macrophages to enhance the inflammatory environment can significantly affect the progression of diseases and tissue engineering repair process. AIM: To assess the influence of interleukin-10 (IL-10) on the osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) following their interaction with macrophages in an inflammatory environment. METHODS: IL-10 modulates the differentiation of peritoneal macrophages in Wistar rats in an inflammatory environment. In this study, we investigated its impact on the proliferation, migration, and osteogenesis of BMSCs. The expression levels of signal transducer and activator of transcription 3 (STAT3) and its activated form, phosphorylated-STAT3, were examined in IL-10-stimulated macrophages. Subsequently, a specific STAT3 signaling inhibitor was used to impede STAT3 signal activation to further investigate the role of STAT3 signaling. RESULTS: IL-10-stimulated macrophages underwent polarization to the M2 type through substitution, and these M2 macrophages actively facilitated the osteogenic differentiation of BMSCs. Mechanistically, STAT3 signaling plays a crucial role in the process by which IL-10 influences macrophages. Specifically, IL-10 stimulated the activation of the STAT3 signaling pathway and reduced the macrophage inflammatory response, as evidenced by its diminished impact on the osteogenic differentiation of BMSCs. CONCLUSION: Stimulating macrophages with IL-10 proved effective in improving the inflammatory environment and promoting the osteogenic differentiation of BMSCs. The IL-10/STAT3 signaling pathway has emerged as a key regulator in the macrophage-mediated control of BMSCs' osteogenic differentiation.

Damage-associated molecular patterns as a mechanism of sevoflurane-induced neuroinflammation in neonatal rodents.

BACKGROUND: General anesthesia is inevitable for pediatric patients undergoing surgery, though volatile anesthetic agents may cause neuroinflammation and neurodevelopmental impairment; however, the underlying pathophysiology remains unclear. We aimed to investigate the neuroinflammation mechanism in developing rat brains associated with sevoflurane exposure time, by identifying the specific damage-associated molecular patterns (DAMPs) pathway and evaluating the effects of non-steroidal anti-inflammatory drugs (NSAIDs) in alleviating neuroinflammation. METHODS: A three-step experiment was conducted to investigate neuroinflammation induced by sevoflurane. First, the exposure time required for sevoflurane to cause neuroinflammation was determined. Next, the specific pathways of DAMPs involved in neuroinflammation by sevoflurane were identified. Finally, the effects of NSAIDs on sevoflurane-induced neuroinflammation were investigated. The expression of various molecules in the rat brain were assessed using immunohistochemistry, immunofluorescence, quantitative real-time polymerase chain reaction, western blot analysis, and enzyme-linked immunosorbent assay. RESULTS: In total, 112 rats (aged 7 days) were used, of which six rats expired during the experiment (mortality rate, 5.3%). Expression of CD68, HMGB-1, galectin-3, TLR4, TLR9, and phosphorylated NF-κB was significantly increased upon 6 h of sevoflurane exposure. Conversely, transcriptional levels of TNF-α and IL-6 significantly increased and IFN-γ significantly decreased after 6 h of sevoflurane exposure. Co-administration of NSAIDs with sevoflurane anesthesia significantly attenuated TNF-α and IL-6 levels and restored IFN-γ levels. CONCLUSIONS: In conclusion, 6 h of sevoflurane exposure induces neuroinflammation through the DAMPs pathway, HMGB-1, and galectin-3. Co-administration of ibuprofen reduced sevoflurane-induced neuroinflammation.

Anti-Proliferative Effects of Lidocaine as an Autophagy Inducer in Bladder Cancer via Intravesical Instillation: In Vitro and Xenograft Mouse Model Experiments.

Lidocaine exerts potential anti-tumor effects on various cancer cell lines, and its intravesical instillation is considered safer than intravenous administration for bladder cancer. However, the mechanisms underlying its anti-tumor effects have not been fully elucidated. Here, we aimed to elucidate the anti-tumor molecular mechanisms of lidocaine in bladder cancer cells and a xenograft model to substantiate the efficacy of its intravesical administration. We investigated the anti-proliferative and autophagyinducing activities of lidocaine in Nara Bladder Tumor No. 2 (NBT-II) rat bladder carcinoma cells using cell viability, flow cytometry, a wound healing assay, and western blotting. We also established a xenograft mouse model of bladder cancer, and cancer growth was examined using in vivo bioluminescence imaging. Lidocaine decreased cell viability, induced G0/G1 phase cell cycle arrest, and inhibited cell migration partially via glycogen synthase kinase (GSK) 3ß phosphorylation. Moreover, a combination of lidocaine and SB216763 (a GSK3ß inhibitor) suppressed autophagy-related protein expression. Bafilomycin-A1 with lidocaine significantly enhanced microtubule-associated protein 1A/1B-light chain (LC3B) expression; however, it decreased LC3B expression in combination with 3-methyladenine compared to lidocaine alone. In the xenograft mouse model, the bladder cancer volume was reduced by lidocaine. Overall, lidocaine exerts anti-proliferative effects on bladder cancer via an autophagy-inducing mechanism.

Plasticity, heterogeneity, and multifunctionality of hepatic stellate cells in liver pathophysiology.

HSCs, the resident pericytes of the liver, have consistently been at the forefront of liver research due to their crucial roles in various hepatic pathological processes. Prior literature often depicted HSCs in a binary framework, categorizing them as either quiescent or activated. However, recent advances in HSC research, particularly the advent of single-cell RNA-sequencing, have revolutionized our understanding of these cells. This sophisticated technique offers an unparalleled, high-resolution insight into HSC populations, uncovering a spectrum of diversity and functional heterogeneity across various physiological states of the liver, ranging from liver development to the liver aging process. The single-cell RNA-sequencing revelations have also highlighted the intrinsic plasticity of HSCs and underscored their complex roles in a myriad of pathophysiological processes, including liver injury, repair, and carcinogenesis. This review aims to integrate and clarify these recent discoveries, focusing on how the inherent plasticity of HSCs is central to their dynamic roles both in maintaining liver homeostasis and orchestrating responses to liver injury. Future research will clarify whether findings from rodent models can be translated to human livers and guide how these insights are harnessed to develop targeted therapeutic interventions.

Nd:YAG water mist laser treatment for giant gestational gingival tumor: A case report.

BACKGROUND: This case of gestational gingival tumor is huge and extremely rare in clinical practice. As the growth location of this gingival tumor is in the upper anterior tooth area, it seriously affects the pregnant woman's speech and food, causing great pain to the patient. The use of Nd:YGA water mist laser to remove the gingival tumor resulted in minimal intraoperative bleeding, minimal adverse reactions, and good postoperative healing, which is worthy of clinical promotion and application. CASE SUMMARY: The patient, a pregnant woman, reported a large lump in her mouth on the first day of postpartum treatment. Based on medical history and clinical examination, the diagnosis was diagnosed as gestational gingival tumor. Postoperative pathological biopsy also confirmed this diagnosis. The use of Nd:YAG water mist laser to remove the tumor resulted in minimal intraoperative bleeding, clear surgical field of view, short surgical time, and good postoperative healing. CONCLUSION: In comparison to traditional surgery, Nd:YAG water mist laser surgery is minimally invasive, minimizes cell damage, reduces bleeding, ensures a clear field of vision, and virtually eliminates postoperative edema, carbonization, and the risk of cross infection. It has unique advantages in oral soft tissue surgery for pregnant patients. Therefore, the clinical application of Nd:YAG water mist laser for the treatment of gestational gingival tumors is an ideal choice.

GPX4-mediated bone ferroptosis under mechanical stress decreased bone formation via the YAP-TEAD signalling pathway.

Fracture of the alveolar bone resorption is a common complication in orthodontic treatment, which mainly caused by extreme mechanical loading. However, the ferroptosis with orthodontic tooth movement(OTM) relationship has not been thoroughly described. We here analysed whether ferroptosis is involved in OTM-associated alveolar bone loss. Mouse osteoblasts (MC-3T3) and knockdown glutathione peroxidase 4 (GPX4) MC-3T3 were stimulated with compressive force loading and ferrostatin-1 (Fer-1, a ferroptosis inhibitor), and the changes in lipid peroxidation morphology, expression of ferroptosis-related factors and osteogenesis levels were detected. After establishing the rat experimental OTM model, the changes in ferroptosis-related factors and osteogenesis levels were reevaluated in the same manner. Ferroptosis was involved in mechanical stress regulating osteoblast remodelling, and Fer-1 and erastin affected osteoblasts under compression force loading. Fer-1 regulated ferroptosis and autophagy in MC-3T3 and promoted bone proliferation. GPX4-dependent ferroptosis stimulated the YAP (homologous oncoproteins Yes-associated protein) pathway, and GPX4 promoted ferroptosis via the YAP-TEAD (transcriptional enhanced associate domain) signal pathway under mechanical compression force. The in vivo experiment results were consistent with the in vitro experiment results. Ferroptosis transpires during the motion of orthodontic teeth, with compression force side occurring earlier than stretch side within 4 h. GPX4 plays an important role in alveolar bone loss, while Fer-1 can inhibit the compression force-side alveolar bone loss. GPX4's Hippo-YAP pathway is activated by the lack of compression force in the lateral alveolar bone.

A positive association between BMI and kidney stones among the diabetic population: a cross-sectional study from NHANES.

BACKGROUND: In the past, research has shown that a higher body mass index (BMI) is one of the variables that increase the likelihood of kidney stones; however, no studies have found a connection between the two in the type II diabetic population. The purpose of this research is to reveal the association between BMI and kidney stones in the type II diabetic population. METHODS: We selected demographic data, laboratory data, lifestyle, and medical history from the NHANES. Specifically includes age, gender, systemic immune-inflammation index (SII), poverty income rate (PIR), body mass index (BMI), kidney stones, education, coronary artery disease, smoking, and drinking. RESULTS: BMI and kidney stones were shown to have a positive association in type II diabetics (blood sugar level > 7.0 mmol/L or diagnosed by a doctor) (OR = 1.021, 95% CI 1.008-1.033, P = 0.001), even after controlling for factors, such as age, gender, race, education level, coronary heart disease, smoking, and drinking. The subgroup analysis revealed a more significant positive association among the 67-80 years, female and Non-Hispanic White population. CONCLUSIONS: There is a positive correlation between BMI and kidney stones among the type II diabetic population.

Effect of high-dose vitamin C on renal ischemia-reperfusion injury.

Acute kidney injury frequently occurs after cardiac surgery, and is primarily attributed to renal ischemia-reperfusion (I/R) injury and inflammation from surgery and cardiopulmonary bypass. Vitamin C, an antioxidant that is often depleted in critically ill patients, could potentially mitigate I/R-induced oxidative stress at high doses. We investigated the effectiveness of high-dose vitamin C in preventing I/R-induced renal injury. The ideal time and optimal dosage for administration were determined in a two-phase experiment on Sprague-Dawley rats. The rats were assigned to four groups: sham, IRC (I/R + saline), and pre- and post-vitC (vitamin C before and after I/R, respectively), with vitamin C administered at 200 mg/kg. Additional groups were examined for dose modification based on the optimal timing determined: V100, V200, and V300 (100, 200, and 300 mg/kg, respectively). Renal I/R was achieved through 45 min of ischemia followed by 24 h of reperfusion. Vitamin C administration during reperfusion significantly reduced renal dysfunction and tubular damage, more than pre-ischemic administration. Doses of 100 and 200 mg/kg during reperfusion reduced oxidative stress markers, including myeloperoxidase and inflammatory responses by decreasing high mobility group box 1 release and nucleotide-binding and oligomerization domain-like receptor 3 inflammasome. Overall beneficial effect was most prominent with 200 mg/kg. The 300 mg/kg dose, however, showed no additional benefits over the IRC group regarding serum blood urea nitrogen and creatinine levels and histological evaluation. During reperfusion, high-dose vitamin C administration (200 mg/kg) significantly decreased renal I/R injury by effectively attenuating the major triggers of oxidative stress and inflammation.

Combination of low- or moderate-intensity statin and ezetimibe vs. high-intensity statin monotherapy on primary prevention of cardiovascular disease and all-cause death: a propensity-matched nationwide cohort study.

AIMS: This study aims to compare the preventive effect of low- or moderate-statin with ezetimibe combination therapy and high-intensity statin monotherapy on cardiovascular disease (CVD) and all-cause death in a real-world setting. METHODS AND RESULTS: Using the Korean National Health Insurance Service datasets, two cohorts comparing high-intensity statin monotherapy with low- or moderate-intensity statin and ezetimibe combination were constructed by 1:1 propensity score matching procedure. Primary outcome was a composite of myocardial infarction (MI), stroke, and all-cause death. Secondary outcome was an individual event. The study population was followed from baseline until the date of events, or the last health check-ups, whichever came first. Compared to high-intensity statin monotherapy, moderate-intensity statin with ezetimibe combination significantly reduced the risk of composite outcome [hazard ratio (HR) 0.84, 95% confidence interval (CI) 0.77-0.92, P < 0.001] as well as individual MI (HR 0.81, 95% CI 0.71-0.94, P = 0.005) and stroke (HR 0.78, 95% CI 0.65-0.93, P = 0.005), but not all-cause death. Low-intensity statin with ezetimibe also significantly reduced the risk of the composite outcomes (HR 0.80, 95% CI 0.66-0.97, P = 0.024) compared to high-intensity statin monotherapy, but the risk of individual outcome did not differ between two groups. Statin and ezetimibe combination demonstrated consistent effect across various subgroups. CONCLUSION: Among people without pre-existing CVD, moderate-intensity statin with ezetimibe combination was superior to high-intensity statin monotherapy in preventing composite outcomes as well as each of MI and stroke. In contrast, low-intensity statin with ezetimibe combination reduced the risk of composite but not individual outcomes.

We compared the preventive effect of low- or moderate-statin with ezetimibe combination and high-intensity statin monotherapy on cardiovascular disease and all-cause death. Low- or moderate-intensity statin with ezetimibe is beneficial for reducing a composite of myocardial infarction (MI), stroke, and all-cause death. Moderate-intensity statin with ezetimibe reduced 19% of MI and 22% of stroke, compared with high-intensity statin. Statin with ezetimibe combination might be attractive bypass for primary prevention, beyond an alternative to high-intensity statin.

Comparison of the Efficacy of Ezetimibe Combination Therapy and High-Intensity Statin Monotherapy in Type 2 Diabetes.

CONTEXT: Low-density lipoprotein cholesterol (LDL-C)-lowering therapy is considerably important in preventing cardiovascular disease (CVD) among patients with diabetes. Studies comparing CVD, stroke, and mortality outcomes of low- or moderate-intensity statins with ezetimibe combination therapy and high-intensity statin monotherapy in patients with diabetes remain lacking. OBJECTIVE: This study compared the primary prevention effect of myocardial infarction (MI), stroke, and all-cause death between combination therapy of low- or moderate-intensity statins and ezetimibe and high-intensity statin monotherapy in patients with diabetes using the Korean National Health Insurance claims database. METHODS: Patients aged ≥20 years with type 2 diabetes and dyslipidemia were enrolled. The combination therapy of low- or moderate-intensity statin and ezetimibe was compared with high-intensity statin monotherapy after a propensity score-matched analysis. The incidence of composite outcomes consisting of MI, stroke, and all-cause death and each component were analyzed. RESULTS: In moderate-intensity statin therapy with ezetimibe combination therapy, LDL-C (74 ± 37.9 mg/dL vs 80.8 ± 38.8 mg/dL, P < .001) and the incidence of composite outcomes were lower (hazard ratio 0.85, 95% CI 0.74-0.98) than those in high-intensity statin monotherapy. Meanwhile, no significant difference was observed in the LDL-C levels and composite outcomes between low-intensity statins with ezetimibe combination therapy and high-intensity statin monotherapy. CONCLUSION: Adding ezetimibe to a moderate-intensity statin in patients with type 2 diabetes has a greater LDL-C-lowering effect and greater primary prevention of composite outcomes than that of high-intensity statin monotherapy.
