Infusion chemotherapy is currently one of the most common intracavitary treatments for MPE. Unfortunately, there is no definitive consensus on which intracavitary infusion drug has the best effect on the treatment. The use of de-platinum-based thoracic perfusion therapy can offer several advantages, such as reducing drug toxicity and contributing to an improvement in patients’ physical condition. Therefore, this study was to investigate the clinical efficacy and safety of de-platinum-based pleural perfusion bevacizumab combined with Brucea Javanica Oil Emulsion Injection (BJOEI) in the treatment of malignant pleural effusion in advanced lung adenocarcinoma. Methods: A total of 60 patients diagnosed with lung adenocarcinoma and malignant pleural effusion were selected from Binzhou People’s Hospital, Shandong Provincial Cancer Hospital, and Binzhou Central Hospital between June 2022 and May 2024, with 30 cases treated in each group. The study was divided into two groups: the treatment group received bevacizumab injection perfusion in combination with intravenous infusion of Brucea Javanica Oil Emulsion Injection (BJOEI), while the control group received bevacizumab injection combined with cisplatin perfusion. To analyze the data and evaluate their efficacy and adverse reactions, such as disease control rate (DCR), overall response rate (ORR), Karnofsky Performance Status (KPS), vascular endothelial growth factor (VEGF), and so forth. Results: Following the treatment, the quality of life scores in both groups exhibited an increase compared to pre-treatment levels. Moreover, the enhancement observed in the treatment group was deemed statistically significant (P = 0.007). Following treatment, The expression of VEGF in the pleural effusion of both groups of patients was significantly decreased, and the disparity within the same group was found to be statistically significant (P P χ2 = 0.317, P = 0.573;χ2 = 0.218, P = 0.640). A stratified analysis of factors influencing the ORR revealed that the ORR in both groups exhibited statistical significance when the previous KPS score was below 70 (χ2 = 5.850, P = 0.016). The main adverse reactions in both groups included nausea, vomiting, gastrointestinal reactions, fatigue, and hematological toxicity. Among them, there was a statistically significant difference in the occurrence of gastrointestinal reactions and fatigue between the two groups (χ2 = 8.148, P = 0.004;χ2 = 6.696, P = 0.010). Conclusion: Bevacizumab, when combined with Brucea Javanica Oil Emulsion Injection (BJOEI), demonstrates noteworthy efficacy in treating malignant pleural effusion. This combination therapy reduces VEGF expression, in which the reduction supports the efficacy of thoracic perfusion and is associated with minimal adverse reactions, contributing to an improvement in patients’ physical condition and overall clinical tolerability, especially for the poor physique, especially in the elderly and KPS score is less than 70. Therefore, it can be considered a recommended approach for managing malignant pleural effusion, offering significant clinical value.展开更多

Increased body mass index (BMI) is a complication among pediatric cancer survivors. Methods: This retrospective single-center study examined BMI changes among a cohort of predominantly Hispanic patients who were treated in South Los Angeles. Data were collected at diagnosis, 1, 2 and 3 years after. Analyses included z-scores derived from calculated BMIs compared over 3 years per gender, diagnosis, and treatment modality. The unhealthy BMI z-score was defined as >1.04. Results: Thirty-four percent of the predominantly Hispanic sample had unhealthy BMI z-scores of >1.04 correlating to at or greater than the 85th percentile for age and gender. The study cohort’s BMI z-scores significantly increased from 0.15 to 1.29 at year 3 (P < 0.0001), putting 55% of this population in the unhealthy category. Median BMI z-score significantly increased to the unhealthy category at 3 years. Conclusions: Due to the predominance of Hispanic patients in this group, culturally sensitive interventions beginning at diagnosis should be considered.展开更多

These provinces include the Hormuz, Shiraz-Kazerun and Nyriz-Jahrum sub-basins. There are more than hundred salt plugs which they have been formed and developed in the southern margin of Iran. The salt structures that originated from Hormuz formation in these areas have been restricted and separated from each other for the first time in this paper. Salt diapirism of these provinces has been triggered earlier by Halokinesis in the Zagros and Persian Gulf basins, but it has affected later by tectonic forces, because orientation, shape and position of salt plugs have been followed from convergence regime (especially in the Zagros hinterland). In the other hand, based on our results from salt plugs in Persian Gulf foreland basin and the Zagros hinterland, Halokinesis triggers has been affected more than Halotectonic forces.展开更多

These wild poliovirus variants are responsible for poliomyelitis, which is in the process of eradication.. In the following lines, we try to show the evolution of VDPV cases across the country in order to understand their chronological dynamics and seasonal influence. Methods: We conducted a cross-sectional study of of VDPV notified in the DRC from 2018 to 2023. Maps of the spatial dynamics of VDPV cases were produced from attack rates with QGIS® (3.22.8). As for temporal dynamics, time series were decomposed and presented in the form of graphs showing the chronological evolution of VDPV cases and their seasonal trend, using R.4.0 software package. Results: A total of 1196 Cases of VDPV types 1, 2 and 3 were recorded in the biological confirmation databases of the INRB and the Expanded Program of Immunization during the study period across25 provinces. The eastern part of the country reporting the most cases. The general trend is upwards, with a peak in 2022 of 527 cases, whereas in 2021 there was a notable drop of 31 cases. Analysis of the temporal breakdown suggests a seasonal pattern, with peaks between the months of September and December, considered being rainy periods in some provinces. Conclusion: During the 6 years of our study (2018 - 2023) almost all the Health Zones were hit by VDPV epidemics. The eastern part was the most impacted. The seasonal component is well marked suggesting a rise in detection in the rainy season and during pivotal periods of climate change.展开更多

This study aimed to determine the prevalence of antimicrobial resistance in bacteria isolated from CMT positive cows on farms located in high (HARA) and low (LARA) acaricide resistance challenge regions of Uganda. Among selected herds in both regions, subclinical mastitis (SCM) screening was performed using CMT. CMT positive samples were collected, cultured, bacteria isolated and antibiotic sensitivity tests conducted. Overall, the prevalence of SCM in cows was 71.5% and 27.7% for HARA and LARA respectively. A SCM herd prevalence of 66.3% and 28.2% was recorded for HARA and LARA respectively. Furthermore, 67.5% and 20.8% of the cows in the HARA and LARA groups, respectively, had three out of four udder quarters infected with SCM. Staphylococcus aureus (44.2%) and coagulase-negative Staphylococcus (CNS) (47.6%) were the most prevalent causative agents of SCM isolated from cows from HARA and LARA, respectively. Most isolates from both regions were highly resistant to penicillin (HARA, 84.3%;LARA, 95.6%) and colistin (HARA, 100%;LARA, 97.8%). Tetracycline (77.1%) and oxacillin (76.1%) resistance was high in isolates from HARA and LARA, respectively. Intermediate responses (neither susceptible nor resistant) to antibiotics were more common in isolates from HARA than in those from LARA. With this level of antibiotic resistance, there is a potential risk of failure to control mastitis in dairy cattle using antibiotics, especially in the HARA region, which may possibly jeopardize the growth of the dairy industry in Uganda.展开更多
