This article aimed to investigate the fractional exhaled carbon monoxide (FeCO) expression level in obstructive sleep apnea-hypopnea syndrome (OSAHS) and its correlation with disease indicators. Subjects with OSAHS, asthma, chronic obstructive pulmonary disease (COPD), and healthy subjects were selected to collect clinical data. FeCO concentration, eosinophil (Eos), erythrocyte sed-imentation rate (ESR), C-reactive protein (CRP), FEV1, and FEV1/FVC were measured. The Pearson correlation coefficient and receiver operating charac-teristic (ROC) curve were used for statistical analysis. The FeCO concentra-tion, Eos count, ESR and CRP levels, and lung function in the OSAHS group were higher than the healthy and COPD groups (p<0.05) and slightly lower than the asthma group. FeCO was positively correlated with Eos, ESR, and CRP (p<0.05), but there was no apparent correlation between FeCO and lung func-tion. FeCO has a high sensitivity and specificity in the diagnosis of OSAHS. There is chronic airway inflammation and systemic inflammation in patients with OSAHS. Lung function impairment in patients with OSAHS is mild, but some limitations remain. FeCO may be an auxiliary diagnostic index particu-larly valuable in diagnosing OSAHS.","PeriodicalId":14515,"journal":{"name":"Investigación Clínica","volume":"90 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140453155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate the effect of experimental folic acid administration on N-methyl-N’-nitro-N-nitrosoguanidine (MNNG)-induced CAG through the PI3K/Akt pathway in rats. The rats were divided into a Model Group, a Folic Acid Group and a Blank Group. Rats in the Model Group were induced by MNNG and given 10 mL/kg/d distilled water by gavage, while rats in the Folic Acid Group were induced by MNNG and given 5 mg/kg/d folic acid suspension by gavage. As a control, rats in the Blank Group were given the same amount of distilled water as MNNG and 10 mL/kg/d distilled water by gavage. The levels of gastrin (GAS) and motilin (MTL) in serum were measured by enzyme-linked immunosorbent assay (ELISA), and the mRNA and protein ex-pressions were detected by quantitative polymerase chain reaction (q-PCR) and Western blot. According to hematoxylin and eosin (H&E) pathological analysis, there were inflammatory factors infiltration and derangement of mucosal epi-thelial cells in the model group, while the gastric tissue injury in the folic acid group was improved. Folic acid could decrease the content of GAS, increase the content of MTL in the serum of the rats, and regulate the expression of PI3K and AKT signal pathways. Folic acid can have a therapeutic effect on CAG by reducing the concentration of GAS in serum and increasing the concentration of MLT in serum. Our study would lay a theoretical foundation for using folic acid to investigate new therapies for CAG in humans.","PeriodicalId":14515,"journal":{"name":"Investigación Clínica","volume":"384 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140453715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seventy TBI patients admitted between January 2020 and January 2021 were catego-rized into good prognosis (n=42) and poor prognosis (n=28) groups according to the Glasgow Outcome Scale (GOS) score upon discharge. Factors affecting prognosis were analyzed, and differences in intracranial pressure and coagula-tion between the two groups were compared. The receiver operating charac-teristic curve (ROC) was used to calculate the predictive value of intracranial pressure-related parameters and coagulation function on prognosis. Within 24 h postoperatively, the good prognosis group had lower levels of intracra-nial pressure (ICP) and partial pressure of oxygen in brain tissue (PbtO2) and higher cerebral perfusion pressure (CPP) and cerebral hemodynamic param-eters than the poor prognosis group (p<0.05). The good prognosis group had significantly lower prothrombin time (PT), activated partial thromboplastin time (aPTT),and prothrombin time (TT) levels and higher platelets (PLT) and fibrinogen (Fib) levels than the poor prognosis group (p<0.05). Regression analysis revealed that CPP, systolic blood flow velocity (Vs), end-diastolic blood flow velocity (Vd), mean blood flow velocity (Vm), PLT, Fib were independent protective factors for the prognosis, and ICP, PbtO2, PT, APTT, and TT were risk factors for prognosis. The ROC revealed that ICP, CPP, PbtO2, Vs, Vd, Vm, APTT, PLT, Fib exhibited high diagnostic value for poor prognosis (AUC=0.732, 0.940, 0.796, 0.706, 0.914, 0.729, 0.876, 0.709, 0.866), with ICP showing the highest diagnostic sensitivity and Vd showing the highest diagnostic specificity.

The sociodemographic and clinical aspects of 96 records of adolescents hospitalized for attempted suicide between Janu-ary 2017 and December 2018 were reviewed, compared, and related. Two study groups were formed: Group I, 14 adolescents previously hospitalized in the Intensive Treatment Unit and Group II, 82 adolescents who did not require this unit. Gender, age, education, history of sexual abuse, diagnoses of mental disorders, co-morbidities, previous mental health consultations, and caregivers with mental disorders were studied. Descriptive statistics and odds ratios were used. In group I, with 92% male adolescents, severe depression was observed in 57% of cases, and 100% of its members suffered sexual abuse; in group II, with 91% female adolescents, 79% moderate depression was found, 85.3% ab-normal personality development and 70% of its members suffered sexual abuse.

Ninety patients who underwent LIHR in our hospital from August 2019 to December 2020 and had peritoneal tears during the operation were selected, and the patients were divided into a control group (CG) and the observation group (OG) according to different treatment plans, with 45 cases in each group. Patients in the CG were treated with absorbable sutures to repair the peritoneal tears, while patients in the OG were treated with bipolar coagulation to close and repair the peritoneal tears. The surgical conditions, postoperative pain scores, quality of life scores, com-plications, and recurrence were compared between the CG and OG groups. The operation time and hospital stay in the OG were shorter than those in the OG (p<0.05). The pain scores in the OG at 24 hours after operation were lower than those in the CG (p<0.05), and the pain scores of the two groups were not significantly different at two hours and 12 hours (p>0.05). Postoperative complications were not significantly different between the groups (p>0.05). The scores of material life, physical, social, and psychological function in the OG were higher than in the CG (p<0.05). There were no recurrences in the two groups during the 1-year follow-up. Closing repair of peritoneal rupture with bipolar coagulation reduces the operation time of patients with peritoneal rup-ture during TEP (total extraperitoneal hernioplasty) operations, reduces pain, and improves their quality of life.
