ABSTRACT

ObjectiveTo investigate the effect of modified Baduanjin exercise, as an rehabilitation exercise, on cardiopulmonary function, motor function and activities of daily living in patients with stroke. MethodsFrom January to September, 2023, 42 stroke patients in the Nanjing Qixia District Hospital were randomly divided into control group (n = 21) and experimental group (n = 21). The control group received routine rehabilitation, and the experimental group received modified Baduanjin exercise in addition, for four weeks. They were assessed with peak oxygen uptake (VO2peak), anaerobic threshold (AT), peak oxygen pulse (VO2peak/HR), forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), peak expiratory flow (PEF), Fugl-Meyer Assessment-upper extremities (FMA-UE), Berg Balance Scale (BBS) and modified Barthel Index (MBI) before and after intervention. ResultsVO2peak, AT, and the scores of FMA-UE, BBS and MBI improved in the control group after intervention (|t| > 2.256, |Z| > 2.936, P < 0.05); while VO2peak, AT, VO2peak/HR, FVC, FEV1, PEF, and the scores of FMA-UE, BBS and MBI improved in the experimental group (|t| > 4.390, |Z| > 3.451, P < 0.001); and all the indexes were better in the experimental group than in the control group (|t| > 4.136,|Z| > 2.751,P < 0.01), except the scores of BBS and MBI. ConclusionModified Baduanjin exercise can improve the cardiopulmonary function and upper limb motor function for stroke patients.

ABSTRACT

ObjectiveTo investigate the effect of galvanic vestibular stimulation on stroke patients with lateropulsion. MethodsFrom February to October, 2023, 30 stroke patients with lateropulsion in the First Affiliated Hospital of Nanjing Medical University were divided into control group (n = 15) and experimental group (n = 15) randomly. The control group received routine rehabilitation and sham galvanic vestibular stimulation, and the experimental group received routine rehabilitation and true galvanic vestibular stimulation, for two weeks. They were assessed with Scale for Contraversive Pushing (SCP), subjective visual vertical (SVV), Line Cancellation Test (LCT), Star Cancellation Test (SCT), Berg Balance Scale (BBS), Holden Functional Ambulation Category (FAC) and Barthel Index (BI) before and after treatment. ResultsAll the indexes improved in both groups after intervention (|t| > 2.461, Z > 3.000, P < 0.05), except the SVV orientation, SVV certainty and SCT in the control group; while the SCP, SVV certainty, LCT and FAC were better in the experimental group than in the control group (|t| > 2.189, Z = -2.862, P < 0.05), and the differences before and after intervention were better in the experimental group than in the control group (|t| > 2.382, P < 0.05), except LCT. SCP was correlated with SVV orientation, SVV certainty, SCT, BBS, BI and FAC (|r| > 0.381, P < 0.05). ConclusionGalvanic vestibular stimulation can improve the lateropulsion, balance, walking function and activities of daily living in stroke patients, which may be related to improvement for spatial cognitive function, especially vertical perception.

ABSTRACT

Background@#Tigecycline, eravacycline, and omadacycline are recently developed tetracyclines. Susceptibility of microbes to these tetracyclines and their molecular mechanisms have not been well elucidated. We investigated the susceptibility of Moraxella catarrhalis to tigecycline, eravacycline, and omadacycline and its resistance mechanisms against these tetracyclines. @*Methods@#A total of 207 non-duplicate M. catarrhalis isolates were collected from different inpatients. The minimum inhibitory concentrations (MICs) of the tetracyclines were determined by broth microdilution. Tigecycline-, eravacycline-, or omadacycline-resistant isolates were induced under In Vitro pressure. The tet genes and mutations in the 16S rRNA was detected by PCR and sequencing. @*Results@#Eravacycline had a lower MIC50 (0.06 mg/L) than tigecycline (0.125 mg/L) or omadacycline (0.125 mg/L) against M. catarrhalis isolates. We found that 136 isolates (65.7%) had the tetB gene, and 15 (7.2%) isolates were positive for tetL; however, their presence was not correlated with high tigecycline, eravacycline, or omadacycline ( ≥ 1 mg/L) MICs.Compared with the initial MIC after 160 days of induction, the MICs of tigecycline or eravacycline against three M. catarrhalis isolates increased ≥ eight-fold, while those of omadacycline against two M. catarrhalis isolates increased 64-fold. Mutations in the 16S rRNA genes (C1036T and/or G460A) were observed in omadacycline-induced resistant isolates, and increased RR (the genes encoding 16SrRNA (four copies, RR1-RR4) copy number of 16S rRNA genes with mutations was associated with increased resistance to omadacycline. @*Conclusions@#Tigecycline, eravacycline, and omadacycline exhibited robust antimicrobial effects against M. catarrhalis. Mutations in the 16S rRNA genes contributed to omadacycline resistance in M. catarrhalis.

ABSTRACT

Objective:To investigate the clinical characteristics and related factors of patients with chronic obstructive pulmonary disease (COPD) complicated by obstructive sleep apnea (OSA).Methods:The clinical data of 153 patients with COPD who received treatment in Xiangyang First People's Hospital from July 2018 to December 2019 were retrospectively analyzed. A total of 101 patients with complete data regarding pulmonary function and polysomnography who met inclusion criteria were selected. They were divided into simple COPD (COPD group, n = 33) and COPD + OSA (OS group, n = 68) groups according to whether they developed OSA. General clinical data, pulmonary function indexes and polysomnography indexes were compared between the COPD and OS groups. Logistic regression analysis was performed to analyze the degree of airflow limitation and the related factors of COPD combined with OSA. Results:There were more males than females in each group. In the OS group, the proportion of males, body mass index, forced expiratory volume in one second (FEV 1), forced expiratory volume in 1 second percent predicted (FEV 1%pred), the ratio of FEV 1 to forced vital capacity (FVC), apnea-hypopnea index and oxygen desaturation index in the OS group were 92.6%, 24.0 (23.4, 24.8) kg/m 2, 1.2 (1.2, 1.5) L, 50.0 (49.6, 59.4)%, 49.1 (46.9, 53.0)%, 15.4 (16.4, 25.3) times/h, 14.8 (17.3, 25.6) times/h, respectively, which were significantly higher than those in the COPD group [75.8%, 23.0 (21.6, 23.7) kg/m 2, 0.9 (0.9, 1.1) L, 41.0 (38.3, 49.1) %, 41.9 (39.5, 49.24)%, 1.9 (1.6, 2.4) times/h, 4.0 (3.7, 9.7) times/h, t or U = 4.246, 1 399.000, 1 544.500, 1 483.000, 1 407.000, 2 244.000, 1 915.000, all P < 0.05]. The lowest oxygen saturation at night in the OS group was significantly lower than that in the COPD group [81.5 (79.4, 82.6) % vs. 87.0 (80.2, 86.6) %, U = 758.500, P < 0.05]. There were no significant differences in age, smoking index and forced vital capacity between COPD and OS groups ( t = - 0.963, 1 150.000, - 1.954, all P > 0.05). Correlation and Logistic regression analysis revealed that the risk of severe or very severe airflow limitation was lower in the OS group than in the COPD group ( OR = 0.392, P < 0.05). BMI, FEV 1, FEV 1%pred were the risk factors of COPD combined with OSA ( OR = 1.185, 5.554, 1.034, all P < 0.05). BMI and FEV 1 were the independent risk factors of COPD combined with OSA ( OR = 1.168, 5.248, both P < 0.05). Conclusion:COPD and OSA are more common in males and in patients with higher BMI. OSA patients tend to develop lower degree of airflow limitation and more severe hypoxemia and apnea-hypopnea at night than COPD patients. Apnea-hypopnea index is the protective factor against airflow limitation in COPD. BMI, FEV 1 and FEV 1%pred are the risk factors of COPD combined with OSA. BMI and FEV 1 are the independent risk factors of COPD combined with OSA.
