RESUMEN
OBJECTIVES: The obesity prevalence in South Korea in 2021 stood at 38.4%. South Korea faces unique challenges in providing essential and emergency guidelines for weight management because of stepping into an aging society. We aimed to determine the daily diet patterns among the general Korean population and to investigate the association between such patterns and different obesity. STUDY DESIGN: Longitudinal prospective cohort study. METHODS: A total of 6539 adult participants (mean age 50.8 years, 52.9% male) with normal-weight adults were included from the Ansan-Ansung cohort of 10,030 Korean adults aged 40 or older and followed for an average of 11 years. Obesity was defined according to the criteria from the Korean Society for The Study of Obesity. Baseline dietary intake was assessed using a validated 103-item food frequency questionnaire. Dietary patterns were derived from k-means cluster analysis. RESULTS: In the multivariate analysis, referring to white rice + baechu kimchi, participants from multigrain rice + baechu kimchi showed lower HR for obesity development (waist circumference defined-obesity; HR: 0.87, 95% CI: 0.79, 0.95; body fat percentage defined-obesity; HR: 0.89, 95% CI: 0.80, 0.98). Further analysis documented that except for body fat percentage defined-obesity, consuming milk or dairy products was linked to a reduced incidence of the other three obesity (body mass index defined-obesity; HR: 0.84, 95% CI: 0.72, 0.99; waist circumference defined-obesity; HR: 0.82, 95% CI: 0.71, 0.94; waist-to-hip ratio defined-obesity; HR: 0.75, 95% CI: 0.61, 0.91). CONCLUSIONS: Following a diet that includes multigrain rice, fermented baechu kimchi, and dairy products is linked to a decreased risk of obesity in Korean adults. Public health programs and policies could incorporate these dietary recommendations, targeting specific population groups such as schoolchildren, adults, and the elderly. Additionally, further research is needed to explore the synergistic effects of various foods and their interactions within dietary patterns on obesity outcomes.
RESUMEN
The traditional treatment modalities for esophageal cancer include surgery, chemotherapy, and radiotherapy, each presenting its own limitations. With advancements in endoscopic techniques and the integration of immunotherapy, the feasibility and safety of organ preservation have significantly improved, offering patients improved survival and quality of life. The selection of patients suitable for organ preservation treatment demands ongoing exploration. Those selected for this approach require rigorous monitoring, with surgical intervention as a salvation for tumor progression or metastasis, though the timing of surgery remains a topic of debate. Organ preservation and watch-and-wait strategy may provide a more conservative treatment option, aiming to maximize quality of life.

Surgery is the primary treatment for esophageal cancer, but the postoperative complication rate remains high. Therefore, it is important to prevent and manage postoperative complications to improve prognosis. Common perioperative complications of esophageal cancer include anastomotic leakage, gastrointestinal tracheal fistula, chylothorax, and recurrent laryngeal nerve injury. Respiratory and circulatory system complications, such as pulmonary infection, are also quite common. These surgery-related complications are independent risk factors for cardiopulmonary complications. Complications, such as long-term anastomotic stenosis, gastroesophageal reflux, and malnutrition are also common after esophageal cancer surgery. By effectively reducing postoperative complications, the morbidity and mortality of patients can be reduced, and their quality of life can be improved.

BACKGROUND: Early detection of cancer offers the opportunity to identify candidates when curative treatments are achievable. The THUNDER study (THe UNintrusive Detection of EaRly-stage cancers, NCT04820868) aimed to evaluate the performance of enhanced linear-splinter amplification sequencing, a previously described cell-free DNA (cfDNA) methylation-based technology, in the early detection and localization of six types of cancers in the colorectum, esophagus, liver, lung, ovary, and pancreas. PATIENTS AND METHODS: A customized panel of 161 984 CpG sites was constructed and validated by public and in-house (cancer: n = 249; non-cancer: n = 288) methylome data, respectively. The cfDNA samples from 1693 participants (cancer: n = 735; non-cancer: n = 958) were retrospectively collected to train and validate two multi-cancer detection blood test (MCDBT-1/2) models for different clinical scenarios. The models were validated on a prospective and independent cohort of age-matched 1010 participants (cancer: n = 505; non-cancer: n = 505). Simulation using the cancer incidence in China was applied to infer stage shift and survival benefits to demonstrate the potential utility of the models in the real world. RESULTS: MCDBT-1 yielded a sensitivity of 69.1% (64.8%-73.3%), a specificity of 98.9% (97.6%-99.7%), and tissue origin accuracy of 83.2% (78.7%-87.1%) in the independent validation set. For early-stage (I-III) patients, the sensitivity of MCDBT-1 was 59.8% (54.4%-65.0%). In the real-world simulation, MCDBT-1 achieved a sensitivity of 70.6% in detecting the six cancers, thus decreasing late-stage incidence by 38.7%-46.4%, and increasing 5-year survival rate by 33.1%-40.4%, respectively. In parallel, MCDBT-2 was generated at a slightly low specificity of 95.1% (92.8%-96.9%) but a higher sensitivity of 75.1% (71.9%-79.8%) than MCDBT-1 for populations at relatively high risk of cancers, and also had ideal performance. CONCLUSION: In this large-scale clinical validation study, MCDBT-1/2 models showed high sensitivity, specificity, and accuracy of predicted origin in detecting six types of cancers.

BACKGROUND: Neoadjuvant therapy is recommended for locally advanced esophageal cancer, but the optimal strategy remains unclear. We aimed to evaluate the safety and efficacy of neoadjuvant chemoradiotherapy (nCRT) versus neoadjuvant chemotherapy (nCT) followed by minimally invasive esophagectomy (MIE) for locally advanced esophageal squamous cell carcinoma (ESCC). PATIENTS AND METHODS: Eligible patients staged as cT3-4aN0-1M0 ESCC were randomly assigned (1 : 1) to the nCRT or nCT group stratified by age, cN stage, and centers. The chemotherapy, based on paclitaxel and cisplatin, was administered to both groups, while concurrent radiotherapy was added for the nCRT group; then MIE was carried out. The primary endpoint was 3-year overall survival. This study is registered with ClinicalTrials.gov (NCT03001596). RESULTS: A total of 264 patients were eligible for the intention-to-treat analysis. By 30 November 2021, 121 deaths had occurred. The median follow-up was 43.9 months (interquartile range 36.6-49.3 months). The overall survival in the intention-to-treat population was comparable between the nCRT and nCT strategies [hazard ratio (HR) 0.82, 95% confidence interval (CI) 0.58-1.18; P = 0.28], with a 3-year survival rate of 64.1% (95% CI 56.4% to 72.9%) versus 54.9% (95% CI 47.0% to 64.2%), respectively. There were also no differences in progression-free survival (HR 0.83, 95% CI 0.59-1.16; P = 0.27) and recurrence-free survival (HR 1.07, 95% CI 0.71-1.60; P = 0.75), although the pathological complete response in the nCRT group (31/112, 27.7%) was significantly higher than that in the nCT group (3/104, 2.9%; P < 0.001). Besides, a trend of lower risk of recurrence was observed in the nCRT group (P = 0.063), while the recurrence pattern was similar (P = 0.802). CONCLUSIONS: NCRT followed by MIE was not associated with significantly better overall survival than nCT among patients with cT3-4aN0-1M0 ESCC. The results underscore the pending issue of the best strategy of neoadjuvant therapy for locally advanced bulky ESCC.

Adenocarcinoma of the esophaogastric junction (AEG) has anatomical characteristics of spanning two organs and anatomical sites. Thoracic surgery and gastrointestinal surgery aim at the safe resection margin of esophagus, the scope of lower mediastinal lymph node dissection and whether transthoracic surgery will increase complications. However, there are great differences and controversies in the surgical approach, surgical method, lymph node dissection and extent of resection of AEG. For Siewert II AEG via abdominal mediastinal approach, due to the limitation of exposure and the difficulty of operation, it is difficult to acquire a satisfactory proximal resection margin, and very difficult to dissect the inferior mediastinal lymph nodes. The transthoracic approach can provide adequate exposure, reduce the difficulty of operation, obtain satisfactory resection margin of esophagus and allow lower mediastinal lymph node dissection, which may bring better prognosis. Although transthoracic approach may increase the incidence of pulmonary infection, the standard development of thoracoscopic technology will overcome the disadvantage of transthoracic approach for Siewert II AEG.

Objective: To summarize survival outcomes and prognostic factors in esophageal cancer (EC) patients treated with intensity-modulated radiotherapy (IMRT). Methods: A retrospective analysis was performed on the clinical and follow-up data of 1 637 patients with EC who were admitted to our hospital from January 2005 to December 2017 and met the inclusion criteria.The 5-year overall survival (OS), progression-free survival (PFS) and pattern of recurrence were analyzed. The Kaplan-Meier method was used to calculate survival rates, Log-rank test for univariate analysis and Cox method for multivariate analysis were used to detect survival difference. Results: 1-year, 3-year and 5-year OS and PFS of the entire group were 65.9% and 45.8%, 34.2% and 25.0%, 27.0% and 18.5%, respectively. Median OS and PFS were 19.4 months (95% CI=18.0-20.7 months) and 10.4 months (95% CI=9.3-11.3 months), respectively. Univariate analysis showed that the sex, KPS, tumor location, T stage, N stage, M stage, TNM stage, radiation dose and treatment modality were prognostic factors for 5-year OS and PFS of EC patients (P<0.05). Multivariate analysis indicated that the sex, KPS, TNM stage, radiation dose and treatment modality were independent prognostic factors for 5-year OS and PFS (P<0.05). Conclusions: EC patients treated with IMRT can obtain a promising survival. The sex, KPS, TNM stage, radiation dose and treatment modality are independent prognostic factors for prognosis.

BACKGROUND: Small bowel volvulus is defined as the torsion of the small intestine, potentially leading to bowel obstruction, gangrene and perforation. It is a rare condition, especially in adults. CASE PRESENTATION: A 30-year-old man was retrieved from the jungle with severe weight loss and abdominal symptoms. He succumbed to death despite 22 days of intensive medical treatment. An autopsy revealed a ruptured gangrenous ileal volvulus with peritonitis and subdiaphragmatic abscess. Further laboratory analysis detected systemic Candida tropicalis and intestinal gramnegative bacterial sepsis, systemic Zika virus viremia, leptospirosis complicating rhabdomyolysis and disseminated intravascular coagulopathy, Type I Herpes Simplex virus infection of the tongue and upper gastrointestinal tract. The cause of death was the ruptured ileal volvulus, complicated with upper gastrointestinal bleeding due to Herpes simplex virus esophagitis in a malnourished patient with resolving leptospirosis and underlying Zika virus co-infection. CONCLUSION: Rare clinical scenarios of adult-onset intestinal volvulus with concomitant multiple infections precludes clinical diagnosis and early treatment, leading to devastating consequences of clinical outcome. The positive clinical and postmortem correlation is a good learning lesson in many disciplines of medicine and science.

RESUMEN
Objective: To investigate the epidemiological characteristics and current status of surgical management for esophageal cancer in China. Methods: A national database was setup through a network platform. The clinical data of esophageal cancer treated by surgery was collected from 70 major hospitals in China between January 2009 and December 2014. Results: Complete data of 8 181 cases of esophageal cancer patients who underwent surgery were recorded in the database and recruited in the analysis. Among them, 6 052 cases were male and 2 129 were female, the average age was 60.5 years.The epidemiological investigation results showed that 148 cases (1.8%) had history of psychological trauma, 7 527 cases (92.0%) were lower social economic status, 5 072 cases (62.0%) were short of fresh vegetables and fruits, 6 544 cases (80.0%) ate rough food frequently, 3 722 cases (45.5%) drank untreated water directly from lake or river or shallow well, 3 436 cases (42.0%) had a unhealthy eating habit, including habits of eating food fast (507 cases, 6.2%), eating hot food or drinking hot tea/soup (998 cases, 12.2%), eating fried food (1 939 cases, 23.7%), 4 410 cases (53.9%) had the habits of smoking cigarettes and 2 822 cases (34.5%) drank white wine frequently.The pathological results showed that 7 813 cases (95.5%) were squamous cell carcinoma, 267 cases were adenocarcinoma (3.3%), 25 cases were adenosquamous cell carcinoma (0.3%) and 50 cases were small cell carcinoma (0.6%). A total of 1 800 cases (22.0%) received preoperative neoadjuvant therapy due to locally advanced disease or difficulty of resection. The esophagectomies were performed through left thoracotomy approach in 5 870 cases (71.8%), through right chest approach in 2 215 cases (27.1%), and the remain 96 cases (1.2%) received surgery though other approaches.A total of 8 001 cases (97.8%) underwent radical resection, the other 180 cases (2.2%) received palliative resection. The 30-day postoperative mortality rate was 0.5%, the overall ≥ grade â ¡ postoperative complication rate was 11.6% (951 cases). The 1-yr, 3-yr, and 5-yr overall actual survival rates were 82.6%, 61.6%, and 52.9%, respectively. Conclusions: The data analysis of the national database for esophageal cancer shows that bad eating habits or eating rough food without enough nutrients, lower social and economic status, drinking white wine and smoking cigarettes frequently may be correlated with tumorigenesis of esophageal cancer. However, strong evidences produced by prospective observation studies are needed. Overall, the long-term survival of esophageal cancer patients has been improved gradually due to the application of advanced surgical techniques and reasonable multimodality treatment.

OBJECTIVE: To detect the expression of long non-coding ribonucleic acid (lncRNA) ASB16-AS1 in non-small cell lung cancer (NSCLC) tissues and cells, and to explore the effect of lncRNA ASB16-AS1 on the biological functions of NSCLC cells. PATIENTS AND METHODS: The expression level of lncRNA ASB16-AS1 in NSCLC tissues and cells was detected via real-time fluorescence quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR). The interference sequences of lncRNA ASB16-AS1 were designed and synthesized, and its transfection efficacy was detected by qRT-PCR. After knockdown of lncRNA ASB16-AS1, the proliferation, cell cycle, and apoptosis of NSCLC cells were detected via cell counting kit-8 (CCK-8) assay, colony formation assay, and flow cytometry, respectively. Moreover, the expression changes in the Wnt/ß catenin signaling pathway were detected via Western blotting. RESULTS: LncRNA ASB16-AS1 was upregulated in NSCLC tissues and cells compared with that in paracarcinoma tissues and 16HBE cells. The results of CCK-8 assay and colony formation assay revealed that the silence of lncRNA ASB16-AS1 attenuated the proliferative ability in NSCLC. The results of flow cytometry manifested that the silence of lncRNA ASB16-AS1 arrested the cell cycle in G0/1 phase, and accelerated the apoptosis rate. The key proteins in the Wnt/ß-catenin signaling pathway were regulated by lncRNA ASB16-AS1 in NSCLC. CONCLUSIONS: LncRNA ASB16-AS1 is upregulated in NSCLC tissues and cells, which promotes proliferation and inhibits apoptosis of NSCLC cells through the Wnt/ß-catenin signaling pathway.

BACKGROUND: Low adult immunization rates leave adults at risk from infectious disease, and the resulting complications of vaccine-preventable diseases. Standing orders protocols (SOPs) for adult immunization have not been implemented widely in clinics serving adult patients. Our purpose was to evaluate the impact of SOPs on adult immunization rates and identify challenges to sustaining adult immunization coverage rates after implementation of SOPs. METHODS: Baseline adult vaccination rates were calculated for the year prior to SOPs implementation in 5 diverse clinics. Vaccines included in the implemented standing orders included Tdap, influenza, pneumococcal, human papillomavirus, herpes zoster, and hepatitis B. Adult vaccination rates were tracked for 1 year after SOPs implementation. RESULTS: Sites generally sustained modest gains in coverage rates (4%-8% increase) after SOP implementation, but greater success was found in practices that used SOPs as a foundation on which additional interventions were built. Challenges to increasing coverage rates included prioritization of acute and chronic conditions over adult vaccination, Medicare Part D reimbursement policies, electronic medical record issues related to data reporting and programming for patient alerts, and the lack of interoperability between the state immunization information system (missing patient vaccination history) and electronic medical record. CONCLUSIONS: SOPs may provide a good starting point for increasing adult immunization coverage rates. Using additional interventions, quality-based metrics, or incentives could lead to sustained adult immunization prioritization.

Radiation therapy is the first choice for the treatment of nasopharyngeal carcinoma. However, it is inevitable that nasopharyngeal mucosa and tissue will be damaged after radiotherapy of nasopharyngeal carcinoma, which will cause corresponding complications. Nasopharyngeal osteonecrosis is a serious complication. Up to now, there are few reports about nasopharyngeal osteonecrosis, and the underlaying pathological mechanism remains unclear. The potential theories include radiotherapy damage, infection and trauma, but also the " three H" principle of hypoxic hypocellular hypovascular tissue, as well as the theory of radio induced fibrosis. It is controversial about the treatment of nasopharyngeal osteonecrosis. It takes comprehensive treatment, including local treatment, systemic treatment, surgical treatment and other treatments. Among them, local treatment as nasopharyngeal debridement usually is first choice. We reviewed the pathological mechanism and treatment methods of nasopharyngeal osteonecrosis, in order to provide a reference for better prevention and treatment of it.
RESUMEN
OBJECTIVES: With ENCODE epigenomic data and results from published genome-wide association studies (GWASs), we aimed to find regulatory signatures of obesity genes and discover novel susceptibility genes. METHODS: Obesity genes were obtained from public GWAS databases and their promoters were annotated based on the regulatory element information. Significantly enriched or depleted epigenomic elements in the promoters of obesity genes were evaluated and all human genes were then prioritized according to the existence of the selected elements to predict new candidate genes. Top-ranked genes were subsequently applied to validate their associations with obesity-related traits in three independent in-house GWAS samples. RESULTS: We identified RAD21 and EZH2 as over-represented, and STAT2 (signal transducer and activator of transcription 2) and IRF3 (interferon regulatory transcription factor 3) as depleted transcription factors. Histone modification of H3K9me3 and chromatin state segmentation of 'poised promoter' and 'repressed' were over-represented. All genes were prioritized and we selected the top five genes for validation at the population level. Combining results from the three GWAS samples, rs7522101 in ESRRG (estrogen-related receptor-γ) remained significantly associated with body mass index after multiple testing corrections (P=7.25 × 10(-5)). It was also associated with ß-cell function (P=1.99 × 10(-3)) and fasting glucose level (P<0.05) in the meta-analyses of glucose and insulin-related traits consortium (MAGIC) data set.Cnoclusions:In summary, we identified epigenomic characteristics for obesity genes and suggested ESRRG as a novel obesity-susceptibility gene.

OBJECTIVE: To calculate the survival rate of patients with superficial esophageal squamous carcinoma who received esophageal resection and to explore factors that affect prognosis. METHODS: There were 285 patients with pTis-T1 esophageal carcinoma who underwent esophagectomy during 2007-2011. Their cumulative survival rates were calculated using life tables. Nine factors that may have impact on postoperative survival of superficial esophageal carcinoma were selected. The Kaplan-Meier method and COX's regression model were used to select prognostic factors, estimate prognostic index, and establish risk stratification. RESULTS: The 1-, 3- and 5-year overall survival rates of superficial esophageal carcinoma patients were 97%, 86%, and 82%, respectively. Tumor length, stenosis, depth of invasion, differentiation degree, lymph node metastasis, and vascular tumor thrombus were associated with prognosis according to univariate analysis. Depth of invasion (OR=2.065, P=0.029), lymph node metastasis (OR=2.049, P=0.041), differentiation degree (OR=3.828, P=0.000), stenosis(OR=2.129, P=0.048), and vascular tumor thrombus (OR=4.222, P=0.004) were independent prognostic factors in multivariate analysis. A prognostic models was thus established and all the patients were divided into low-risk, moderate-risk and high-risk group, with the 3-year survival rates being 95%, 84%, and 51%, and 5-year survival rates being 93%, 79%, and 44%, respectively. CONCLUSIONS: Patients with superficial esophageal cancer have relatively favorable prognosis. Depth of invasion, differentiation degree, stenosis, lymph node metastasis, and vascular tumor thrombus may be independent factors of poor prognosis. Survival rate of moderate- and high-risk patients is yet to be improved.

This report summarizes the first meeting of a panel of immunization experts who met in Washington, DC, on May 4-5, 2012. The panel consisted of experts from national immunization policy organizations; state, regional, and local immunization programs; and vaccinating health care practices. The primary objective of this meeting was to identify issues in the vaccine delivery process as a critical first step in the determination of where and how improvements can be made. Vaccines are one of the greatest achievements in public health. However, in order to maintain the integrity of vaccines and the success of vaccination programs, proper handling of vaccines from the receipt of shipment through administration to the patient is critical. Continuous improvement of the vaccine delivery process is important to ensure appropriate vaccine handling by all vaccine providers. The overarching consensus of the participants of this meeting was that the major challenge in vaccine delivery is the complexity throughout all areas of the vaccine delivery process, which is often underestimated, particularly in the areas of vaccine preparation and administration. The lack of detailed, consistent standards encompassing all areas of the vaccine delivery process, and the gaps in oversight, education, and training of vaccine providers, particularly providers of adult vaccines, were also identified as major issues. The next step for this panel is to reconvene to explore potential solutions to address the identified issues.

RESUMEN
UNLABELLED: This study aims at investigating the effects of age, sex, and ethnicity on five femoral neck geometric parameters (FNGPs): femoral neck periosteal diameter, cross-sectional area, cortical thickness, sectional modulus, and buckling ratio and found that the three factors would influence the FNGPs. INTRODUCTION: Bone geometry is one of the most important predictors of bone strength and osteoporotic fractures. This study aims at investigating the effects of age, sex, and ethnicity on five femoral neck geometric parameters (FNGPs): femoral neck periosteal diameter (W), cross-sectional area (CSA), cortical thickness (CT), sectional modulus (Z), and buckling ratio (BR). METHODS: In the studied 861 Caucasian subjects and 3,021 Chinese individuals, CSA, CT, and Z displayed trends of decrease with age, but W and BR showed increasing trends with age in both Chinese and Caucasian females and males (p < 0.05). W, CSA, CT, and Z were significantly higher (p Asunto(s)

RESUMEN
BACKGROUND: Access to sterile syringes is a proven means of reducing the transmission of human immunodeficiency virus (HIV), viral hepatitis, and bacterial infections among injection drug users. In many U.S. states and territories, drug paraphernalia and syringe prescription laws are barriers to syringe access for injection drug users (IDUs): pharmacists may be reluctant to sell syringes to suspected IDUs, and police may confiscate syringes or arrest IDUs who cannot demonstrate a "legitimate" medical need for the syringes they possess. These barriers can be addressed by physician prescription of syringes. This study evaluates physicians' willingness to prescribe syringes, using the theory of planned behavior to identify key behavioral influences. METHODS: We mailed a survey to a representative sample of physicians from the American Medical Association physician database. Non-responding physicians were then called, faxed, or re-sent the survey, up to four times. RESULTS: Twenty percent responded to the survey. Although less than 1 percent of respondents had ever prescribed syringes to a known injection drug user, more than 60% of respondents reported that they would be willing to do so. Physicians' willingness to prescribe syringes was best predicted by the belief that it was a feasible and effective intervention, but individual and peer attitudes were also significant. CONCLUSION: This was the first nationwide survey of the physician willingness to prescribe syringes to IDUs. While the majority of respondents were willing to consider syringe prescription in their clinical practices, multiple challenges need to be addressed in order to improve physician knowledge and attitudes toward IDUs.

The isolation of Mycoplasma hyosynoviae from a piglet with severe pneumonia is described. This is the first report of M. hyosynoviae isolation in the country. The lung sample where the isolation was made was severely consolidated, suppurative and pleurisy. The pathogenicity of the M. hyosynoviae isolated has yet to be determined.
