Objective: To investigate the treatment outcomes and influencing factors among elderly patients with pulmonary tuberculosis in Lishui City, Zhejiang Province, so as to provide a basis for optimizing the prevention and control strategies of pulmonary tuberculosis and reducing the risk of adverse treatment outcomes among elderly patients. Methods: Data on patients aged ≥60 years with pulmonary tuberculosis in Lishui City from 2016 to 2022 were collected from the Tuberculosis Information Management System of the China Disease Prevention and Control Information System, including basic information, diagnosis and treatment details, and laboratory test results. The successful treatment rate and the incidence of adverse treatment outcomes were calculated. Factors affecting adverse treatment outcomes among elderly patients with pulmonary tuberculosis were analyzed using multivariable logistic regression model. Results: A total of 3 094 elderly patients with pulmonary tuberculosis were registered in Lishui City from 2016 to 2022, with a median age of 70 (interquartile range, 13) years. There were 2 396 male patients (77.44%) and 698 female patients (22.56%). A total of 2 676 patients achieved successful treatment, with a successful treatment rate of 86.49%. The successful treatment rate demonstrated a significant upward trend from 2016 to 2022 (P<0.05). There were 418 patients with adverse treatment outcomes, accounting for an incidence of 13.51%. The main types of adverse outcomes were death and loss to follow-up, with 199 and 100 patients, accounting for 47.61% and 23.92%, respectively. Multivariable logistic regression analysis showed that elderly patients with pulmonary tuberculosis who were male (OR=1.333, 95%CI: 1.018-1.745), aged ≥70 years (70-<80 years, OR=1.909, 95%CI: 1.469-2.481; ≥80 years, OR=3.878, 95%CI: 2.967-5.068), living in rural areas (OR=1.332, 95%CI: 1.068-1.661), with positive etiological results (OR=1.470, 95%CI: 1.143-1.889), and undergoing retreatment (OR=1.923, 95%CI: 1.419-2.607) had a higher risk of adverse treatment outcomes. Conclusions The successful treatment rate showed an upward trend among elderly patients with pulmonary tuberculosis in Lishui City from 2016 to 2022. Gender, age, place of residence, etiological results, and treatment type were influencing factors for adverse treatment outcomes among elderly patients with pulmonary tuberculosis.

Objective:To explore the current situation and influencing factors of quality of life of septic patients in intensive care unit (ICU) after discharge, and to provide theoretical basis for clinical early psychological intervention and continuity of care.Methods:A prospective observational study was conducted. The septic patients who were hospitalized in the department of critical care medicine of the Affiliated Hospital of Jining Medical University and discharged with improvement from January 1 to December 31, 2022 were selected as the research objects. The demographic information, basic diseases, infection site, vital signs at ICU admission, severity scores of the condition within 24 hours after ICU admission, various biochemical indexes, treatment process, and prognostic indexes of all the patients were recorded. All patients were assessed by questionnaire at 3 months of discharge using the 36-item short-form health survey scale (SF-36 scale), the activities of daily living scale (ADL scale), and the Montreal cognitive assessment scale (MoCA scale). Multiple linear regression was used to analyze the factors influencing the quality of life of septic patients after discharge from the hospital.Results:A total of 200 septic patients were discharged with improvement and followed up at 3 months of discharge, of which 150 completed the questionnaire. Of the 150 patients, 57 had sepsis and 93 had septic shock. The total SF-36 scale score of septic patients at 3 months of discharge was 81.4±23.0, and the scores of dimensions were, in descending order, role-emotional (83.4±23.0), mental health (82.9±23.6), bodily pain (82.8±23.3), vitality (81.6±23.2), physical function (81.4±23.5), general health (81.1±23.3), role-physical (79.5±27.0), and social function (78.8±25.2). There was no statistically significant difference in the total SF-36 scale score between the patients with sepsis and septic shock (82.6±22.0 vs. 80.7±23.6, P > 0.05). Incorporating the statistically significant indicators from linear univariate analysis into multiple linear regression analysis, and the results showed that the factors influencing the quality of life of septic patients at 3 months after discharge included ADL scale score at 3 months after discharge [ β= 0.741, 95% confidence interval (95% CI) was 0.606 to 0.791, P < 0.001], length of ICU stay ( β= -0.209, 95% CI was -0.733 to -0.208, P = 0.001), duration of mechanical ventilation ( β= 0.147, 95% CI was 0.122 to 0.978, P = 0.012), total dosage of norepinephrine ( β= -0.111, 95% CI was -0.044 to -0.002, P = 0.028), mean arterial pressure (MAP) at ICU admission ( β= -0.102, 95% CI was -0.203 to -0.007, P = 0.036) and body weight ( β= 0.097, 95% CI was 0.005 to 0.345, P = 0.044). Conclusions:The quality of life of patients with sepsis at 3 months after discharge is at a moderately high level. The influencing factors of the quality of life of patients with sepsis at 3 months after discharge include the ADL scale score at 3 months after discharge, the length of ICU stay, the duration of mechanical ventilation, the total dosage of norepinephrine, MAP at ICU admission and body weight, and healthcare professionals should enhance the treatment and care of the patients during their hospitalization based on the above influencing factors, and pay attention to early psychological intervention and continued care for such patients.

Objective:To evaluate the effect of prior statins use on the in-hospital mortality of adult sepsis patients with type 2 diabetes (T2DM).Methods:A total of 3 545 sepsis patients with T2DM were retrospectively collected from the Critical Care Medical Information Market (MIMIC Ⅳ) database, with in-hospital mortality rate as the outcome variable. According to whether they have taken statins in the past, they were divided into two groups and propensity score matching was used. Multivariate Cox regression analysis was performed to calculate the adjusted hazard ratio ( HR) and 95% CI, and the relationship between past statins use and in-hospital mortality in sepsis patients with T2DM was analyzed. Results:A total of 3 545 sepsis patients with T2DM were included between 2008 and 2016. 1 556 patients used statins before admission, and 1 989 patients did not use statins. After propensity score matching, the number of patients who had previously used statins and those who had not used statins were 1 230 and 1 298, respectively. After adjusting for potential confounding factors, it was found that previous use of statins was associated with a reduced in-hospital mortality rate ( HR=0.82, 95% CI: 0.61-0.99, P=0.038). Kaplan Meier curves showed that sepsis patients with T2DM who used statins before admission had a lower in-hospital mortality rate (Log rank test: P<0.001). Conclusions:Pre admission use of statins may be associated with a reduced mortality rate in sepsis patients with concomitant T2DM.

Objective:This paper explores the predictive value of indicators of cardiopulmonary exercise test in the degree of coronary artery disease in patients with coronary heart disease.It provides an objective basis for predicting the degree of coronary artery disease by non-invasive detection methods in patients with coronary heart disease,and provides objective guidance for formulating exercise prescriptions for patients with coronary heart disease. Method:Fifty-three patients with coronary heart disease who were treated in the Affiliated Cardiovascular Hospi-tal of Kunming Medical University from March 2020 to May 2022 were selected to complete coronary angiogra-phy and cardiopulmonary exercise test.According to the coronary angiography results and the SYNTAX score,the patients were divided into low group(SYNTAX≤22 points)with 30 cases and medium-high group(SYN-TAX＞22 points)with 23 cases.The general information of the patients such as gender,age,BMI and comor-bidities were collected,and the indicators of cardiopulmonary exercise test were collected. Result:Compared with the medium-high group,maximum oxygen uptake(VO2max),maximum oxygen uptake as a percentage of the predicted value(VO2max％P),maximum metabolic equivalent(METSmax),maximum heart rate(HRmax)and maximum heart rate as a percentage of predicted value(HR％P)of the low group were high-er,and the difference between the two groups was statistically significant with p-value less than 0.05.Com-pared with the medium-high group,the heart rate reserve(HRR)in the low group was lower,and the differ-ence between the two groups was statistically significant with p-value less than 0.05.The SYNTAX score was negatively correlated with VO2max,VO2max％P,maximum oxygen uptake in kilograms(VO2max/kg),METSmax,HRmax and HR％P,and positively correlated with HRR with P-value less than 0.05.HRR has the highest sensitivity in predicting coronary heart disease. Conclusion:The low group with low SYNTAX scores and mild coronary lesions has higher VO2max,VO2max％P,VO2max/kg,METSmax,HRmax and HR％P values,suggesting that the patients in this group have better cardiopulmo-nary reserve function and better exercise capacity.The high group with severe coronary artery disease has high-er HRR,and the gap between the maximum heart rate and the target heart rate during exercise is larger,which means it is more difficult for patients in the high group to reach the target heart rate.

Objective:To investigate the effects of ceftriaxone(CTX) on nuclear factor erythroid 2-related factor 2(Nrf2)/glutathione peroxidase 4(GPX4) pathway and ferroptosis in early brain injury in rats with subarachnoid hemorrhage(SAH).Methods:Forty-eight clean grade male SD rats were randomly divided into sham operation group (Sham group), SAH group, SAH+ CTX group and SAH+ CTX+ Nrf2 inhibitor group (SAH+ CTX+ ML385 group) according to the random number table with 12 rats in each group.Seven days before modeling, rats in SAH+ CTX+ ML385 group were injected intraperitoneally with ML385 (30 mg · kg -1) once a day for consecutive 7 days.And 5 days before modeling, rats in SAH+ CTX group and SAH+ CTX+ ML385 group were treated with CTX(200 mg · kg -1) by intraperitoneal injection once a day for five consecutive days.Rats in Sham group and SAH group were intraperitoneally injected with the same amount of 0.9% sodium chloride solution.After 24 hours of modeling, the neurological function score and brain tissue water content of rats in each group were measured.HE staining was used to observe the morphology of neurons in CA1 and CA3 regions of hippocampus.Prussian blue staining was used to observe the iron deposition in cerebral cortex.Spectrophotometer was used to determine the iron content, malonic dialdehyde(MDA) content, glutathione(GSH) content and GPX4 activity in cerebral cortex.Western blot was used to detect the expression levels of Nrf2 and GPX4 proteins in cerebral cortex.SPSS 23.0 was used for statistical analysis.One-way ANOVA was used to compare the mean of multiple groups of samples, and Dunnett- t test was used for further pairwise comparison between groups. Results:There was a statistically significant difference in the neurological function scores of rats in the four groups 24 hours after SAH ( F=48.40, P<0.001). The neurological function score of rats in the SAH group 24 hours after SAH was significantly lower than those in Sham group and SAH+ CTX group (both P<0.05). The brain water content of rats in the four groups 24 h after SAH was statistically significant ( F=49.61, P<0.001). The brain water content of rats in the SAH group 24 h after SAH was significantly higher than that in Sham group and SAH+ CTX group(both P<0.05). There was statistically significant differences in the number of neuronal necrosis in CA1 and CA3 regions of hippocampus in the four groups 24 hours after SAH ( F=17.44, 246.50, both P<0.001). The numbers of neuronal necrosis in CA1 and CA3 regions of hippocampus in SAH group were significantly higher than those in Sham group and SAH+ CTX group, and the numbers of neuronal necrosis in CA1 and CA3 regions of hippocampus in SAH+ CTX+ ML385 group were significantly higher than those in SAH+ CTX group (all P<0.05). Twenty-four hours after SAH, the amount of iron deposited in the cerebral cortex of rats in the four groups was statistically significant ( F=2 363.0, P<0.001). The iron deposition in the cerebral cortex of rats in the SAH group was significantly higher than those in Sham group and SAH+ CTX group (both P<0.05). There were significant differences in iron content, MDA content, GSH content and GPX4 activity in the cerebral cortex of the four groups 24 h after SAH( F=2 380.0, 1 322.0, 789.1, 815.5, all P<0.001). The content of iron and MDA in the cerebral cortex of rats in SAH group were significantly higher than those in Sham group, while the content of GSH and the activity of GPX4 were significantly lower than those in Sham group (all P<0.05). The content of iron and MDA in the cerebral cortex of rats in SAH+ CTX group were lower than those in SAH group, and the content of GSH and the activity of GPX4 were higher than those in SAH group (all P<0.05). At 24 h after SAH, the expression levels of Nrf2 and GPX4 protein in the cerebral cortex of the four groups were statistically significant ( F=888.7, 1 556.0, both P<0.001). The protein expression levels of Nrf2 (0.382±0.014) and GPX4 (0.329±0.019) in the cerebral cortex in SAH group were lower than those in Sham group ((0.746±0.009), (0.953±0.009)) (both P<0.05). The expression levels of Nrf2 (0.631±0.006) and GPX4 (0.833±0.008) protein in the cerebral cortex in the SAH+ CTX group were significantly higher than those in the SAH group (both P<0.05). The expression levels of Nrf2 (0.427±0.009) and GPX4 (0.525±0.011) protein in the cerebral cortex in SAH+ CTX+ ML385 group were significantly lower than those in SAH+ CTX group (both P<0.05). Conclusion:Ceftriaxone may inhibit ferroptosis during EBI in SAH rats by regulating Nrf2/GPX4 signal axis.

BACKGROUND: This study aimed to determine the reasons for conversion and elucidate the safety and efficacy of transition to tenofovir alafenamide/emtricitabine/bictegravir sodium (TAF/FTC/BIC) in highly active antiretroviral therapy (HAART)-experienced HIV-infected patients in real-world settings. METHODS: We conducted a retrospective cohort study. The treatment conversion rationales, safety, and effectiveness in 1684 HIV-infected patients with previous HAART experience who switched to TAF/FTC/BIC were evaluated at Beijing Ditan Hospital from September 2021 to Auguest 2022. RESULTS: Regimen simplification (990/1684, 58.79%) was the most common reason for switching, followed by osteoporosis or osteopenia (375/1684, 22.27%), liver dysfunction (231/1684, 13.72%), decline in tenofovir alafenamide/emtricitabine/elvitegravir/cobicistat (TAF/FTC/EVG/c) with food restriction (215/1684, 12.77%), virological failure (116/1684, 6.89%), and renal dysfunction (90/1684, 5.34%). In patients receiving non-nucleotide reverse transcriptase inhibitors (NNRTI)-containing regimens, lipid panel changes 1 year after switching indicated a difference of 3.27 ± 1.10 mmol/L vs . 3.40 ± 1.59 mmol/L in triglyceride ( P  = 0.014), 4.82 ± 0.74 mmol/L vs . 4.88 ± 0.72 mmol/L in total cholesterol ( P  = 0.038), 3.09 ± 0.70 mmol/L vs . 3.18 ± 0.66 mmol/L in low-density lipoprotein ( P  <0.001), and 0.99 ± 0.11 mmol/L vs . 0.95 ± 0.10 mmol/L in high-density lipoprotein ( P  <0.001). Conversely, among patients receiving booster-containing regimens, including TAF/FTC/EVG/c and lopinavir/ritonavir (LPV/r), lipid panel changes presented decreased trends. We also observed an improved trend in viral load suppression, and alanine transaminase (ALT), aspartate transaminase (AST), estimated glomerular filtration rate (eGFR), and serum creatinine levels after the transition ( P  <0.001). CONCLUSION The transition to TAF/FTC/BIC demonstrated good treatment potency. Furthermore, this study elucidates the motivations behind the adoption of TAF/FTC/BIC in real-world scenarios, providing clinical evidence supporting the stable conversion to TAF/FTC/BIC for HAART-experienced patients.

Objective:To construct a targeted and accurate evaluation system for facial and cervical wounds and scars of burn patients.Methods:The method combining literature analysis and survey research was adopted, and the basic principles of item system construction were followed. From June to August 2020, based on the aesthetic standards of facial and cervical plastic surgery, the topographic map assessment system for facial and cervical wounds and scars of burn patients was preliminarily formed, focusing on the assessment of wounds and scars in the necks and faces of patients after burns. In September 2020, 38 experts in the relevant fields were consulted in advance and the questionnaire was revised according to the experts' opinions. From December 2020 to March 2021, the Delphi method was applied to conduct inquiry by correspondence with 35 experts in relevant fields from Guangzhou, Shenzhen, Shanghai, Beijing, and other cities, who met the inclusion criteria, and the items were screened and established. The effective recovery rate of inquiry questionnaire was calculated to determine the level of enthusiasm of experts, the average authority coefficient of all items was calculated to determine the level of expert authority, the average importance expert score, the average coefficient of variation, and the average full score rate of all the third-level items were calculated to determine the concentration of expert opinions, the average coefficients of variation and Kendall's harmony coefficients of the importance, sensitivity, and operability expert scores of all the third-level items were calculated to determine the degree of coordination of expert opinions. The Kendall's harmony coefficients for the importance, sensitivity, and operability expert scores of all the third-level items were statistically analyzed with chi-square test.Results:Among the 35 experts consulted by Delphi method, mainly were male, aged (48±10) years, with 8-38 years of working experience, mainly with associate senior titles and above, all with a bachelor's degree or above education background, and of whom 11 were burn experts, 7 were wound repair experts, 4 were plastic surgery experts, and 13 were rehabilitation medicine experts. Finally, a topographic map assessment system for facial and cervical wounds and scars of burn patients was formed, including 4 first-level items, 21 second-level items, 40 third-level items, and 1 mask. The effective recovery rate of inquiry questionnaire was 100% (35/35). The average authority coefficient of all items was 0.89. The average importance expert score was 4.67, the average coefficient of variation of importance expert score was 0.01, and the average full score rate of all the third-level items was 86.3%. The average coefficients of variation of the importance, sensitivity, and operability expert scores of all the third-level items were 0.01, 0.01, and 0.02, respectively. The Kendall's harmony coefficients for the importance, sensitivity, and operability expert scores of all the third-level items were statistically significant (with χ2 values of 1 201.53, 745.67, and 707.07, respectively , P<0.05). Conclusions:The established topographic map assessment system for facial and cervical wounds and scars of burn patients has high scientificity and reliability, which can be used for the evaluation of facial and neck wounds or scars in burn patients.
