RESUMEN
Background and Objective: To compare the efficacy of EUS-guided celiac plexus neurolysis (CPN) and celiac plexus irradiation with iodine-125 (125I) seeds with absolute ethanol for relieving pain in patients with advanced pancreatic cancer. Methods: We retrospectively analyzed data of 81 patients with advanced pancreatic cancer who underwent EUS-CPN or EUS-125I implantation between January 2017 and December 2020. Postoperative pain was assessed using visual analog scale (VAS) scores; self-assessments of quality of life and the median survival time were compared between the 2 groups. Results: EUS-CPN and 125I implantation were performed in 43 and 38 patients, respectively. Postoperative VAS scores were significantly lower than the preoperative levels in both groups. One week after the operation, 26 patients (60.5%) in the EUS-CPN group achieved partial pain relief, whereas no patients in the EUS-125I seed group experienced pain relief. However, after 4 weeks postoperatively, VAS scores had decreased, and the rate of partial pain relief was higher for EUS-125I seeds than for EUS-CPN. Self-assessments of quality of life were similar in both groups during the first 1 month after the procedure. Conclusions: Both EUS-CPN and EUS-125I seeds can safely and effectively relieve pain in patients with advanced pancreatic cancer. Although EUS-125I seeds take additional time to show effects, the extent and duration of pain relief are better compared with CPN, and interestingly, the median survival time was different.
RESUMEN
OBJECTIVE: To analyze the characteristics and prognosis of patients with mucormycosis after chemotherapy for acute leukemia, and to strengthen understanding of the disease. METHODS: 7 cases of acute leukemia (AL) patients diagnosed with mucormycosis by metagenomic next generation sequencing (mNGS) after chemotherapy at the First Affiliated Hospital of Bengbu Medical College from October 2021 to June 2022 were collected, and their clinical data, including clinical characteristics, diagnosis, treatment, and prognosis, were retrospectively analyzed. RESULTS: Among the 7 patients with AL complicated with mucormycosis, there were 3 males and 4 females, with a median age of 52(20-59) years. There were 6 cases of acute myeloid leukemia (AML) and 1 case of acute lymphocytic leukemia (ALL). Extrapulmonary involvement in 4 cases, including 1 case suspected of central nervous system involvement. The median time for the occurrence of mucor infection was 16(6-69) days after chemotherapy and 19(14-154) days after agranulocytosis. The main clinical manifestations of mucormycosis were fever (7/7), cough (3/7), chest pain (3/7) and dyspnea (1/7). The most common chest CT imaging findings were nodules, patchy or mass consolidation (6/7). All patients were treated with posaconazole or voriconazole prophylaxis during neutropenia phase. 5 patients died within 8 months, and the median time from diagnosis to death was 1 month. CONCLUSION: Although prophylactic antifungal therapy is adopted, patients with acute leukemia still have a risk of mucor infection during the neutropenia phase. Fever is the main manifestation in the early stage of mucor infection. The use of intravenous antifungal drugs alone is ineffective and there is a high mortality rate in acute leukemia patients with mucormycosis.

Megalencephaly-polymicrogyria-polydactyly-hydrocephalus syndrome (MPPH), a type of overgrowth syndrome, is characterized by progressive megalencephaly, cortical brain malformations, and distal limb anomalies. Previous studies have revealed that the overactivity of the phosphatidylinositol 3-kinase-Protein kinase B pathway and the increased cyclin D2 (CCND2) expression were the main factors contributing to this disease. Here, we present the case of a patient who exhibited megalencephaly, polymicrogyria, abnormal neuronal migration, and developmental delay. Serum tandem mass spectrometry and chromosome examination did not detect any metabolic abnormalities or copy number variants. However, whole-exome sequencing and Sanger sequencing revealed a de novo nonsense mutation (NM_001759.3: c.829C>T; p.Gln277X) in the CCND2 gene of the patient. Bioinformatics analysis predicted that this mutation may disrupt the structure and surface charge of the CCND2 protein. This disruption could potentially prevent polyubiquitination of CCND2, leading to its resistance against degradation. Consequently, this could drive cell division and growth by altering the activity of key cell cycle regulatory nodes, ultimately contributing to the development of MPPH. This study not only presents a new case of MPPH and expands the mutation spectrum of CCND2 but also enhances our understanding of the mechanisms connecting CCND2 with overgrowth syndromes.

Trace metals play a vital role in a variety of biological processes, but excessive amounts can be toxic and are receiving increasing attention. Trace metals in the environment are released from natural sources, such as rock weathering, volcanic eruptions, and other human activities, such as industrial emissions, mineral extraction, and vehicle exhaust. Lifestyle, dietary habits and environmental quality are the main sources of human exposure to trace metals, which play an important role in inducing human reproductive infertility. The purpose of this review is to summarize the distribution of various trace metals in oocyte and to identify the trace metals that may cause oocyte used in the design and execution of toxicological studies.

Background: Childhood obesity tends to persist into adulthood, predisposing individuals to cardiometabolic risk (CMR). This study aims to investigate the mediating role of cardiorespiratory fitness (CRF) in the associations between multiple fatness indicators and individual CMR markers and clustered CMR-score, and explore sex differences. Methods: We recruited 1,557 children (age: 8 to 10, male/female: 52.7%/47.3%) in September 2022 in Ningbo, China. Physical examinations, overnight fasting blood test, and CRF was evaluated. The CMR-score was calculated by summing age- and sex-specific z scores of four CMR markers, including mean arterial blood pressure, triglycerides, the total cholesterol to high-density lipoprotein cholesterol ratio, and homeostatic model assessment for insulin resistance. Generalized linear mixed models were used to identify the associations, mediation analyses were performed to dissect the function of CRF. Results: Partial correlation analyses revealed positive associations between high fatness indicators (including body mass index [BMI], BMI z score, body fat mass index [BFMI] and waist-to-height ratio [WHtR]) and increased CMR markers, whereas high CRF was associated with decreased CMR markers (all P < 0.05). In the mediation analyses, CRF emerged as a partial mediator, attenuating the relationship between four fatness indicators and CMR-score. Specifically, CRF mediated 6.5%, 7.7%, 5.3%, and 12.5% of the association between BMI, BMI z score, BFMI, WHtR and CMR-score (all P < 0.001). And the mediating effects of CRF between WHtR and four individual CMR markers was particularly robust, ranging from 10.4% to 21.1% (all P < 0.05). What's more, CRF mediates the associations between WHtR and CMR-score more pronounced in girls than boys with a mediation effect size of 17.3% (P < 0.001). Conclusion: In Chinese children, CRF partially mitigates the adverse effects of fatness on CMR, underscoring the significance of enhancing CRF in children.

OBJECTIVE: To detect the expression of RNA methyltransferase 14(METTL14) in bone marrow of patients with newly diagnosed acute myeloid leukemia (AML), and to investigate the clinical and prognostic significance of METTL14 expression in newly diagnosed AML. METHODS: Bone marrow samples were collected from 100 patients with newly diagnosed AML as observation group and 60 patients with iron deficiency anemia AML as control group. And collected the clinical data of the AML patients. Real-time quantitative PCR (qRT-PCR) was used to detect the expression level of METTL14 in AML and IDA patients. The relationship between the expression level of METTL14 and clinicopathological features, prognosis was analyzed. Kaplan-Meier curves were used to analyze the effect of METTL14 on overall survival (OS) in AML patients. Cox risk regression model was used to analyze the prognostic factors affecting in patients with AML. RESULTS: Compared with the control group, the expression of METTL14 was significantly increased in AML patients (P < 0.05). Compared with the METTL14 low-expression group, patients in the METTL14 high-expression group had advanced age, high bone marrow cell number, poor efficacyand poor prognosis(P < 0.05). The overall survival time of patients with the METTL14 high-expression group was significantly shorter than that of the low-expression group (P < 0.05). The high expression of METTL14 was an independent risk factor for poor prognosis in AML. CONCLUSION: METTL14 is significantly overexpressed in AML patients, and its correlated with poor clinicopathological features and poor prognosis. It can be used as a prognostic marker and potential therapeutie target for AML patients.

OBJECTIVE: To analyse and discuss the association of gender differences with the risk and incidence of poststroke aphasia (PSA) and its types, and to provide evidence-based guidance for the prevention and treatment of poststroke aphasia in clinical practice. DATA SOURCES: Embase, PubMed, Cochrane Library and Web of Science were searched from January 1, 2002, to December 1, 2023. STUDY SELECTION: Including the total number of strokes, aphasia, the number of different sexes or the number of PSA corresponding to different sex. DATA EXTRACTION: Studies with missing data, aphasia caused by nonstroke and noncompliance with the requirements of literature types were excluded. DATA SYNTHESIS: 36 papers were included, from 19 countries. The analysis of 168,259 patients with stroke and 31,058 patients with PSA showed that the risk of PSA was 1.23 times higher in female than in male (OR = 1.23, 95% CI = 1.19-1.29, P < 0.001), with a prevalence of PSA of 31% in men and 36% in women, and an overall prevalence of 34% (P < 0.001). Analysis of the risk of the different types of aphasia in 1,048 patients with PSA showed a high risk in females for global, broca and Wenicke aphasia, and a high risk in males for anomic, conductive and transcortical aphasia, which was not statistically significant by meta-analysis. The incidence of global aphasia (males vs. females, 29% vs. 32%) and broca aphasia (17% vs 19%) were higher in females, and anomic aphasia (19% vs 14%) was higher in males, which was statistically significant (P < 0.05). CONCLUSIONS: There are gender differences in the incidence and types of PSA. The risk of PSA in female is higher than that in male.

BACKGROUND: The increasing prevalence of childhood obesity has become an urgent public health problem, evidence showed that intervention for childhood obesity bring enormous health benefits. However, an effective individualized intervention strategy remains to be developed, and the accompanying remission of related complications, such as nonalcoholic fatty liver disease (NAFLD), needs to be assessed. This study aimed to develop an m-Health-assisted lifestyle intervention program targeting overweight/obese children and assess its effectiveness on indicators of adiposity and NAFLD. METHODS: This is a cluster-randomized controlled trial that conducted in children with overweight/obesity in Ningbo city, Zhejiang Province, China. Students in Grade 3 (8-10 years old) were recruited from six primary schools, with three be randomized to intervention group and three to usual practice group. The intervention program will last for one academic year and consists of health education, dietary guidance, and physical activity reinforcement. This program is characterized by encouraging four stakeholders, including School, Clinic, famIly, and studENT (SCIENT), to participate in controlling childhood obesity, assisted by m-Health technology. Assessments will be conducted at baseline and 3 months, 9 months, 24 months, and 36 months after baseline. The primary outcome will be the differences between the two groups in students' body mass index and fatty liver index at the end of the intervention (9 months after baseline). During the implementation process, quality control methods will be adopted. DISCUSSION: The program will test the effectiveness of the m-Health-assisted lifestyle intervention on children with obesity and NAFLD. The results of this study will provide evidence for establishing effective lifestyle intervention strategy aimed at childhood obesity and NAFLD and may help develop guidelines for the treatment of obesity and NAFLD in Chinese children. TRIAL REGISTRATION: Clinicaltrials.gov NCT05482191. Registered on July 2022.

Senescence of vascular smooth muscle cells (VSMCs) contributes to aging-related cardiovascular diseases by promoting arterial remodelling and stiffness. Ferroptosis is a novel type of regulated cell death associated with lipid oxidation. Here, we show that pro-ferroptosis signaling drives VSMCs senescence to accelerate vascular NAD+ loss, remodelling and aging. Pro-ferroptotic signaling is triggered in senescent VSMCs and arteries of aged mice. Furthermore, the activation of pro-ferroptotic signaling in VSMCs not only induces NAD+ loss and senescence but also promotes the release of a pro-senescent secretome. Pharmacological or genetic inhibition of pro-ferroptosis signaling, ameliorates VSMCs senescence, reduces vascular stiffness and retards the progression of abdominal aortic aneurysm in mice. Mechanistically, we revealed that inhibition of pro-ferroptotic signaling facilitates the nuclear-cytoplasmic shuttling of proliferator-activated receptor-γ and, thereby impeding nuclear receptor coactivator 4-ferrtin complex-centric ferritinophagy. Finally, the activated pro-ferroptotic signaling correlates with arterial stiffness in a human proof-of-concept study. These findings have significant implications for future therapeutic strategies aiming to eliminate vascular ferroptosis in senescence- or aging-associated cardiovascular diseases.

OBJECTIVE: To analyze the expression of MCP-1 and CCR2 in newly diagnosed diffuse large B-cell lymphoma (DLBCL), and to evaluate their correlation with clinicopathological features and prognosis. METHODS: A total of 141 patients with DLBCL diagnosed and treated in the Department of Hematology, the First Affiliated Hospital of Bengbu Medical College from January 2017 to May 2022 were retrospectively collected. The clinical characteristics, pathological data and prognostic factors of the patients were collected. Immunohistochemical staining was used to detect the expression of MCP-1 and CCR2 in the tissues of newly treated DLBCL patients, and to analyze the relationship between MCP-1 and clinical characteristics, prognosis and survival of patients. RESULTS: The expression of MCP-1 and CCR2 were correlated with Ann Arbor stage, IPI score, lactate dehydrogenase (LDH), Ki-67 index and therapeutic effect. There were no significant correlation between the expression of MCP-1 or CCR2 and other clinical histopathological parameters such as gender, age, ß2-microglobulin, BCL-2, BCL-6, Hans classification, initial location, B symptoms, bone marrow involvement. There was a statistical difference in OS and PFS between the MCP-1 or CCR2 positive group and the negative group, which was associated to poor prognosis.Univariate Cox regression analysis showed that ß2-microglobulin, Ki-67 index, IPI score, MCP-1, CCR2 expression levels and disease remission affected the PFS and OS of DLBCL patients (P < 0.05). Gender, age, LDH, BCL-2, BCL-6, Hans classification, primary tumor site, B symptoms, bone marrow involvement, Ann Arbor stage had no effect on PFS and OS (P >0.05). Multivariate analysis showed that ß2-microglobulin, Ki-67 index, IPI score, MCP-1, CCR2 expression levels and disease remission were independent influencing factors of patients (P < 0.05). CONCLUSION: The expression rate of MCP-1 or CCR2 in newly treated DLBCL is high, and it is correlated with the clinical features of poor prognosis such as stage and LDH of DLBCL patients, which is a poor prognostic factor affecting PFS and OS.

Since November 2019, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has caused the worldwide pandemic of the coronavirus disease 2019 (COVID-19), the impact of which is huge to the lives of world populations. Many studies suggested that such situation will continue due to the endless mutations in SARS-CoV-2 genome that result in complexity of the efforts for the control of SARS-CoV-2, since the special enrichment of nucleotide substitution C>U in SARS-CoV-2 sequences were discovered mainly due to the editing by human host factors APOBEC3 genes. The observation of SARS-CoV-2 variants Beta (B.1.351) and Omicron (B.1.1.529) firstly spreading in South Africa promoted us to hypothesize that genetic variants of APOBEC3 special in African populations may be attributed to the higher mutation rate of SARS-CoV-2 variants in Africa. Current study was conducted to search for functional variants of APOBEC3 genes associate with COVID-19 hospitalization in African population. By integrating data from the 1000 Genomes Project, Genotype-Tissue Expression (GTEx), and Host Genetics Initiative (HGI) of COVID-19, we identified potential functional SNPs close to APOBEC3 genes that are associated with COVID-19 hospitalization in African but not with other populations. Our study provides new insights on the potential contribution of APOBEC3 genes on the evolution of SARS-CoV-2 mutations in African population, but further replication is needed to confirm our results.

Background: Early-stage ampullary adenomas have only been reported in a small case series on endoscopic management. Hence, this study aimed to evaluate the long-term outcomes of early ampullary adenoma with endoscopic management and identify the risk factors for acute pancreatitis after endoscopic papillectomy (EP). Methods: In this study, 115 patients who underwent EP at Changhai Hospital (Shanghai, China) between January 2012 and December 2018 were retrospectively analysed. Endoscopy was performed at 1, 3, 6, and 12 months after EP. Data were statistically analysed using the t-test or the Mann-Whitney U test. Results: A total of 107 patients were included in this study and the follow-up period was 75 ± 43 months. The average age of the 107 patients was 54.6 years and the average tumor size was 17 mm. The average age of the patients (53.7 ± 10.7 years vs 55.2 ± 10.5 years, P = 0.482), minimum tumor size (13 vs 19 mm, P = 0.063), and complete resection rate (84.78% vs 85.25%, P = 0.947) did not differ significantly between the stent placement and non-stent placement groups. Post-EP acute pancreatitis rates in the non-stent placement and stent placement groups were 11.48% and 4.35%, respectively. The risk of post-EP acute pancreatitis was significantly associated with the preoperative carcinoembryonic antigen level in univariate analysis, but not in multivariate analysis. The risk of post-EP acute pancreatitis was not significantly associated with the placement of the pancreatic stent in either univariate or multivariate analysis. Moreover, delayed proximal pancreatic duct stenosis was not noted in either group during long-term follow-up. Conclusions: EP is a satisfactory option for treating adenomas of the ampulla of the duodenum.
RESUMEN
BACKGROUND AND OBJECTIVES: Dexmedetomidine (DEX) is widely used in clinical sedation which has little effect on cardiopulmonary inhibition, however the mechanism remains to be elucidated. The basal forebrain (BF) is a key nucleus that controls sleep-wake cycle. The horizontal limbs of diagonal bundle (HDB) is one subregions of the BF. The purpose of this study was to examine whether the possible mechanism of DEX is through the α2 adrenergic receptor of BF (HDB). METHODS: In this study, we investigated the effects of DEX on the BF (HDB) by using whole cell patch clamp recordings. The threshold stimulus intensity, the inter-spike-intervals (ISIs) and the frequency of action potential firing in the BF (HDB) neurons were recorded by application of DEX (2 µM) and co-application of a α2 adrenergic receptor antagonist phentolamine (PHEN) (10 µM). RESULTS: DEX (2 µM) increased the threshold stimulus intensity, inhibited the frequency of action potential firing and enlarged the inter-spike-interval (ISI) in the BF (HDB) neurons. These effects were reversed by co-application of PHEN (10 µM). CONCLUSION: Taken together, our findings revealed DEX decreased the discharge activity of BF (HDB) neuron via α2 adrenergic receptors.

Introduction: Introduction: dysphagia is a common complication of stroke, and serum albumin is widely recognized as a strong prognostic marker of health and/or disease status. However, the correlation between dysphagia and serum albumin levels has not been established. Objectives: to observe the correlation between dysphagia and serum albumin levels and prognosis in patients with stroke. Methods: we performed a retrospective study of patients hospitalized between June 1, 2018, and June 1, 2022. A total of 1,370 patients were enrolled. The patients were divided into two groups: dysphagia and non-dysphagia. Binary logistic regression and multiple linear regression models were used to analyze the correlation between dysphagia, albumin, modified Rankin Scale (mRS), activities of daily living (ADL), and length of hospital stay (LOS). Results: after adjusting for confounding factors, the risk of pneumonia in the dysphagia group was 2.417 times higher than that in the non-dysphagia group (OR = 2.417, 95 % CI: 1.902-3.072, p = 0.000). The risk of mRS ≥ 3 and modified Barthel index (MBI) < 60 in patients with dysphagia was 3.272-fold (OR = 3.272, 95 % CI: 2.508-4.269, p < 0.001) and 1.670-fold (OR = 1.670, 95 % CI: 1.230-2.268, p < 0.001), respectively; and the risk of hypoproteinemia was 2.533 times higher (OR = 2.533, 95 % CI: 1.879-3.414, p = 0.000). Stepwise linear regression showed that dysphagia was significantly correlated with lower albumin levels and higher mRS, lower ADL, and longer LOS in patients with stroke (ß = -0.220, ß = 0.265, ß = -0.210, and ß = 0.147, respectively; p < 0.001). Conclusions: dysphagia in patients with stroke is associated with decreased albumin levels and has an impact on its prognosis.
Introducción: Introducción: la disfagia es una complicación común del accidente cerebrovascular, y la albúmina sérica es ampliamente reconocida como un fuerte marcador pronóstico del estado de salud y/o enfermedad. Sin embargo, no se ha establecido la correlación entre la disfagia y los niveles de albúmina sérica. Objetivos: observar la correlación entre la disfagia y los niveles de albúmina sérica y el pronóstico en pacientes con accidente cerebrovascular. Métodos: realizamos un estudio retrospectivo de pacientes hospitalizados entre el 1 de junio de 2018 y el 1 de junio de 2022. Se inscribieron un total de 1.370 pacientes, los cuales fueron divididos en dos grupos: con disfagia y sin disfagia. Se utilizaron modelos de regresión logística binaria y de regresión lineal múltiple para analizar la correlación entre la disfagia, la albúmina, la escala de Rankin modificada (ERm), las actividades de la vida diaria (AVD) y el tiempo de estancia hospitalaria (TEH). Resultados: después de ajustar por factores de confusión, el riesgo de neumonía en el grupo de disfagia fue 2,417 veces mayor que en el grupo sin disfagia (OR = 2,417, IC 95 %: 1,902-3,072, p = 0,000). El riesgo de ERm ≥ 3 y el índice de Barthel modificado (MBI) < 60 en pacientes con disfagia se multiplicó por 3,272 veces (OR = 3,272, IC 95 %: 2,508-4,269, p < 0,001) y 1,670 veces (OR = 1,670, IC 95 %: 1,230-2,268, p < 0,001), respectivamente; el riesgo de hipoproteinemia fue 2,533 veces mayor (OR = 2,533, IC 95 %: 1,879-3,414, p = 0,000). La regresión lineal por pasos mostró que la disfagia se correlacionó significativamente con niveles más bajos de albúmina y ERm más altos, AVD más bajos y TEH más prolongados en pacientes con accidente cerebrovascular (ß = -0,220, ß = 0,265, ß = -0,210 y ß = 0,147, respectivamente; p < 0,001). Conclusiones: la disfagia en pacientes con accidente cerebrovascular se asocia a una disminución de los niveles de albúmina y repercute en su pronóstico.
RESUMEN
INTRODUCTION: Prior studies have found inconsistent results regarding the relationship between vitamin D status and Idiopathic Central Precocious Puberty (ICPP). OBJECTIVE: To assess the role of serum 25-hydroxyvitamin D (25 [OH]D) levels in ICPP development. METHOD: The authors retrospectively collected data from 221 girls with ICPP and 144 healthy girls between January 2017 and December 2019. The participants' serum 25(OH)D levels were measured using an automatic chemiluminescence method, and the association between serum 25(OH)D levels and the risk of ICPP was assessed using multivariate logistic regression analysis. Odds Ratios (OR) with 95% Confidence Intervals (95% CI) were calculated as effect estimates. RESULTS: Serum 25(OH)D levels in the ICPP group were significantly lower than those in healthy controls (p < 0.001). Multivariate analysis indicated that girls with insufficient vitamin D levels (OR = 0.201; 95% CI 0.094-0.428; p < 0.001) and sufficient vitamin D levels (OR = 0.141; 95% CI 0.053-0.375; p < 0.001) both had a lower risk of ICPP than girls with vitamin D deficiency. Moreover, the authors found that the height (p = 0.014), weight (p = 0.014), breast stage (p = 0.010), mother's height (p < 0.001), and luteinizing hormone/follicle-stimulating hormone ratio (p = 0.010) in girls with ICPP could be associated with levels of vitamin D. CONCLUSION: This study found that a low serum 25(OH)D level is an independent risk factor for ICPP, and several characteristics of girls with ICPP could be affected by their vitamin D status.

BACKGROUND AND AIMS: Genetic variants in 17-ß hydroxysteroid dehydrogenase 13 (HSD17B13) were demonstrated to protect against NAFLD, which is highly related with insulin resistance and dyslipidemia. However, the effects of NAFLD associated HSD17B13 variants on circulating glucose and lipids have not been adequately investigated in children. This study aimed to investigate associations between single nucleotide polymorphisms (SNPs) of HSD17B13 and NAFLD or its related phenotypes, such as blood glucose and serum lipids in Chinese children. METHODS AND RESULTS: We studied 1027 Chinese Han children aged 7-18 years old, which included 162 NAFLD children and 865 controls without NAFLD. Three SNPs (rs13112695, rs7692397, rs6834314) in HSD17B13 were genotyped. The multivariable logistic and linear regression models were applied to detect the associations between three SNPs and NAFLD or its related phenotypes [alanine transaminase (ALT), fasting plasma glucose (FPG) and serum lipids]. The effect allele A of rs7692397 was negatively associated with FPG [ß (SE) = -0.088 (0.027) mmol/L, P = 0.001], whereas the effect allele G of rs6834314 was positively associated with FPG (ß (SE) = 0.060 (0.019) mmol/L, P = 0.002). After Bonferroni correction, the significant associations still remained (both P < 0.0024). No significant associations were found for NAFLD or serum lipids. CONCLUSION: The study firstly revealed the association between two HSD17B13 variants and FPG in Chinese children, providing evidence for HSD17B13 variants and abnormal glucose metabolism.
RESUMEN
Background: Breathing exercises improve oxidative stress in healthy young adults and patients with diabetes, hypertension, and chronic obstructive pulmonary disease. Furthermore, the mechanism of respiratory intervention is controversial. Therefore, in this meta-analysis, we aimed to systematically evaluate the effects of breathing exercises on oxidative stress biomarkers in humans and provide evidence for the clinical application of breathing exercises. Methods: The Embase, PubMed, Cochrane Library, Web of Science, CNKI, and WANFANG databases were searched for studies about the effects of breathing exercises on human oxidative stress levels, with no restraints regarding time, race, or language. The experimental group included various breathing exercises, and the outcome index included malondialdehyde, superoxide dismutase, and glutathione, nitric oxide, vitamin C, or total antioxidant capacity levels from a randomized controlled trial. Data were extracted by more than two authors and reviewed by one author. Results: Ten studies were included from five countries. Data from patients with no disease, chronic obstructive pulmonary disease, hypertension, or diabetes were included. Participants who performed breathing exercises had greater changes in the included biomarkers than those who did not, suggesting that these biomarkers can be used to evaluate oxidative stress after respiratory interventions. Conclusion: Breathing exercises increased SOD and GSH activities and decreased MDA content.

RESUMEN
Dysphagia has been classified as a "geriatric syndrome" and can lead to serious complications that result in a tremendous burden on population health and healthcare resources worldwide. A characteristic age-related change in swallowing is defined as "presbyphagia." Medical imaging has shown some changes that seriously affect the safety and efficacy of swallowing. However, there is a general lack of awareness of the effects of aging on swallowing function and a belief that these changes are part of normal aging. Our review provides an overview of presbyphagia, which has been a neglected health problem for a long time. Attention and awareness of dysphagia in the elderly population should be strengthened, and targeted intervention measures should be actively implemented.
