OBJECTIVES: To evaluate the impact of HBV infection on pre- and postpartum health-related quality of life (HRQoL) in pregnant women. METHODS: A prospective matched cohort consisting of 70 HBV-infected and 70 healthy pregnant women was recruited from the Fifth Affiliated Hospital of Guangzhou Medical University between April 17 and September 25, 2023. HRQoL of the participants was assessed at 16-24 weeks of gestation, between 32 weeks and delivery, and 5-13 weeks postpartum. Mixed linear models were used for evaluating temporal trends of HRQoL changes, and univariate ANOVA with multiple linear regression was used to identify the predictors of HRQoL. RESULTS: Compared with healthy pregnant women, HBV-infected pregnant women had consistently lower total HRQoL scores across all the 3 intervals, with the lowest scores observed between 32 weeks of gestation and delivery, during which these women had significantly reduced mental component scores (74.27±13.43 vs 80.21±12.9, P=0.009) and postpartum mental (76.52±16.19 vs 85.02±6.51, P<0.001) and physical component scale scores (77.17±14.71 vs 83.09±10.1, P=0.009). HBV infection was identified as an independent risk factor affecting HRQoL during late pregnancy and postpartum periods. Additional independent risk factors for postpartum HRQoL reduction included self-pay medical expenses, spouse's neutral attitude toward the current pregnancy, and preexisting comorbidities (all P<0.05). CONCLUSIONS HRQoL of pregnant women deteriorates progressively in late pregnancy, and HBV infection exacerbates reductions of physical function and role emotion in late pregnancy and after delivery, suggesting the importance of targeted interventions for financial burdens, partner support and comorbid conditions to improve HRQoL of pregnant women with HBV infection.

Objective To investigate the safety and efficacy of Remimazolam combined with nalbuphine in painless endoscopic mucosal resection(EMR)of colorectal polyps.Methods A total of 100 patients who undergo painless colorectal polyp EMR were randomly divided into nalbuphine combined with remimazolam(NR)and nalbuphine combined with propofol(NP),with 50 patients in each group.The mean arterial pressure,heart rate and oxygen saturation were recorded after entry(T0),1min after administration(T1),1min at the beginning of surgery(T2),3min(T3),5min(T4),and at the end of surgery(T5).The frequency of application of vasoactive drugs,their operation time,consciousness vanishing time,recovery time,the times of supplementary sedation,dosage of incidence of nalbuphine,adverse reactions,The satisfaction of doctors and patients were compared.Results The mean arterial pressure of T1,T2,T3,T4 and T5 in the NR group was higher than that in the NP group(P<0.05),and the heart rate of T1 in the NR group was higher than that in the NP group(P<0.05).The incidence of respiratory depression,hypotension,injection pain,the recovery time and the frequency of application of vasoactive drugs in the NR group was lower than that in the NP group(P<0.05).The satisfaction of doctors in the NR group was higher than that in the NP group(P<0.05).There was no significant difference between the two groups in the operation time,oxygen saturation,the times of supplementary sedation,the dosage of incidence of nalbuphineincidence of dizziness,nausea and vomiting,and other adverse reactions(P>0.05).Conclusion Nalbuphine combined with remimazolam can be used safely in the EMR,has few perioperative adverse effects,and is a good choice for painless EMR.

Objective To explore whether remote ischemic preconditioning(RIPC)can prolong the time of ultra-intense exercise(110%VO2max)by increasing the maximum cumulative oxygen deficit(MA-OD),and the specific ways of energy supply of the anaerobic metabolic system.Methods Twenty-four racquet athletes(22.2±2.0 years;174±9 cm;67.1±12.4 kg)completed three supramaximal intensi-ty tests on a treadmill at 110%VO2max intensity to exhaustion separated with Control,Placebo and RIPC interventions.RIPC was induced on the limbs on both sides(5×5 min alternating bilateral occlu-sion 220 and 60 mmHg for Placebo and RIPC interventions,respectively).Moreover,all groups under-went a fourth test with incremental load,and a fifth test with constant load at 40%,50%,60%,70%and 80%VO2max.Results The time to exhaustion and the MAOD of the RIPC group were both greater than those in the Placebo and Control groups(P<0.05).However,no significant differences were found in the average alternative maximal accumulated oxygen deficit(MAODALT),lactic anaerobic metabolism,alactic anaerobic metabolism and parameters of excess post-exercise oxygen consump-tion dynamic curve of the three groups(P>0.05).Meanwhile,in the RIPC group,the average MAOD was significantly higher than MAODALT(P<0.05).Pearson correlation analysis showed a significant rela-tionship between the improvement of MAOD and an increase in exhaustion time after RIPC interven-tion.Conclusion RIPC can improve supramaximal exercise performance of racquet athletes by enhanc-ing their MAOD,and the enhancement of glycolysis energy supply and lactic acid elimination is a po-tential intermediary of the improvement of sports performance.
