After a median of 9.3months of follow-up, the median PFS was 9.3months versus 4.4months, and the median OS was not estimable yet versus 12months for Child-Pugh A versus B patients, respectively. Prior nivolumab failure was the only significant factor associated with poorer PFS (HR = 3.253, p = 0.004). Child-Pugh class B (HR = 2.646, p = 0.039) and prior nivolumab failure (HR = 3.340, p = 0.014) were independent factors for poorer OS in multivariate analysis.
A high DCR was observed by lenvatinib/pembrolizumab combination without adverse effect on ALBI score for systemic therapy-naïve and -experienced uHCC. Suboptimal response to prior nivolumab-failed patients requires further exploration.

The current study aimed to investigate the effects of legumes inclusion in the hypocaloric dietary approaches to stop hypertension (DASH) diet on fasting plasma glucose (FPG) and cardiometabolic risk factors in overweight and obese patients with type 2 diabetes over 16weeks. Also, the modulatory effects of rs7903146 variant in the transcription factor 7 like 2 (TCF7L2) gene that is associated with the risk of diabetes, were assessed on these cardiometabolic risk factors.
This study was a randomized controlled trial. Three-hundred participants, aged 30-65years, whose TCF7L2 rs7903146 genotype was determined, were studied. The participants were randomly assigned to receive either the hypocaloric DASH diet or a hypocaloric legume-based DASH diet. The primary outcome was the difference in FPG change from baseline until the 16-week follow-up between the two dietary interventions. The secondary outcomes were differences in insulin resistance and lipid profile changes between the dietary intervention diets.
A reduction in FPG, insulin, homeostatic model assessment for insulin resistance (HOMA-IR), triglyceride, total cholesterol, and low-density lipoproteincholesterol (LDL-C) was observed at week 16 in both hypocaloric dietary interventions. Compared to the DASH diet, the legume-based DASH diet decreased the FPG and HOMA-IR. There is no interaction between rs7903146 and intervention diets on glycemic parameters.
The DASH diet, enrich in legumes, could improve the glycemic parameters in participants with type 2 diabetes, regardless of having rs7903146 risk or non-risk allele.

Patient safety in the Operating Room (OR) depends on unobstructed team communication. Yet the typical OR is loud, containing numerous sounds from surgical machinery overlayed with human-caused sounds. Our objective was to compare machine vs human-caused sounds for their loudness and distraction, and potential impact on team communication.
After surveying OR staff about sounds that interfere with job performance and team communication, we recorded 19 machine and 48 human-caused sounds measuring their acoustical intensity. We compared peak measures of machine vs human-caused sound loudness, using Student's t-test. We observed the effect of these sounds on OR staff in 59 live surgeries, rating level of interference with team function. We visually depicted competing sounds through a spectral analysis.
The survey response rate was 62.8%. 93% of respondents indicated that OR noise, especially human-caused sounds such as irrelevant conversations, interfere with team communication, hearing, and focus. OR peak decibel levels ranged from 56.8dB (surgical packaging) to 105.0dB (kicked metal stepstool). Human-caused sounds were comparable to machine-caused sounds in terms of mean peak dB levels (77.0 versus 73.8dB, p = 0.32), yet were rated as more interfering with surgical team function. The spectral analysis illustrated both machine and human-caused sound sources obscuring the surgeon's instructions.
Avoidable human-caused sounds are a major source of disruption in the OR and interfere with communication and job performance. We recommend surgical team training to minimize these distractions.

In this study, we evaluate the outcome of renal function in patients undergoing juxtarenal abdominal aortic aneurysm repair with or without division of the left renal vein with special focus on the role of the communicating lumbar vein.
A retrospective analysis of prospectively collected data of 110 patients undergoing elective juxtarenal abdominal aortic aneurysm repair between 2000 and 2018 was performed. The demographic characteristics and comorbidities were reviewed in detail and the renal function was analysed pre- and post-operatively. The cohort of patients was split into group A (left renal vein divided) and B (left renal vein mobilised). Group A was further sub-analysed regarding the presence of a communicating lumbar vein on preoperative imaging data (group A+ = vein present, group A- = no communicating lumbar vein present).
The patients were matched well regarding their demographic characteristics and comorbidities. In the analysis of renal function, no statistically significant difference could be detected between group A and B. In the sub-analysis of group A, the group with a communicating lumber vein (group A+) turned out to have a significantly better renal function in the long term (sCrea 0.87 vs. 1.51; p = 0.016).
Ligation of the left renal vein is a safe procedure in surgery of juxtarenal aortic aneurysms regarding the outcome of the renal function. A communicating lumbar vein between the left renal vein and the left ascending lumbar vein seems to play a key role to provide venous drainage after division of the left renal vein.

Bariatric surgery has been associated with iron, folate, and vitamin B12 deficiencies, which can lead to anemia. This study compares the incidence of anemia between sleeve gastrectomy (SG) and one-anastomosis gastric bypass (OAGB).
Patients from a prospectively collected database of patients with morbid obesity undergoing a primary bariatric procedure from April 2013 to September 2018 were included. Statistical analysis was performed using the general estimation equation. Patients were followed for 6, 12, 24, and 36months post-surgery.
The present study included 2618 patients, of whom 72.3% underwent SG and 27.6% underwent OAGB. The majority of the study population were women (75.7%), and the mean age of the participants was 39.5 ± 11.7years. At the end of the follow-up, the excess weight loss percentage was 66.15 in the SG group and 75.41 in the OAGB group (P < 0.05). The incidence of anemia at 12-, 24-, and 36-month was 16.2, 19.7, and 24.3% in the SG group and 28.4, 37.6, and 56.5% in the OAGB group, showing significantly higher incidence in the OAGB than the SG group ([Formula see text] < 0.001). However, there was no significant difference between the SG and OAGB groups regarding the incidence of iron and vitamin B12 deficiency.
The patients undergoing bariatric surgery, especially OAGB, should be closely monitored post-surgery regarding the incidence of anemia, and supplementation in developing countries could be continued even after the first year.

The role of simulation in teaching technical skills to medical students is not yet well defined. Strategies for its use may be especially relevant where teachers, time, and resources are limited, especially in low-middle-income countries.
Sixty-seven third-year and 67 fifth-year medical students at the University of Botswana were taught surgical skills by a trained peer medical student, a medical officer with no specialty training or a staff surgeon. Pre- and post-intervention performance of two basic tasks (simple interrupted suture (SIS) and laparoscopic peg transfer (LPT)) and one complex task (laparoscopic intracorporeal suture (LIS)) were assessed. Selleckchem NCB-0846 Subjective measures of self-perceived performance, preparedness for internship, and interest in surgery were also measured.
The simulation program decreased the time to complete the two basic tasks and improved the objective score for the complex task. Performance of the basic skills improved regardless of the seniority of the instructor while performance of the advanced skill improved more when taught by a staff surgeon. All students had similar improvements in their self-reported confidence to perform the skills, preparedness to assist in an operation and preparedness for internship, regardless of the seniority of their instructor. Students taught by a staff surgeon felt better prepared to assist in laparoscopic procedures.
Simulation-based teaching of defined surgical skills can be effectively conducted by peers and near-peers. The implications are widespread and may be most relevant where time and resources are limited, and where experienced teachers are scarce.

It is assumed that increases in the operating parameters in shake flasks lead to impairments in cell growth and RP production. These effects in cells metabolism are widely associated with high mass transfers and hydrodynamic stress. This study examined the impact of commonly used operational parameters on growth and specific productivity (qP) of two CHO cell lines differentially secreting a humanized anti-hIL8 monoclonal antibody (mAb) and cultured in 250 ml flasks. The evaluated parameters are filling volume (10, 15, and 20%), shaking frequency (60 and 120 revolutions per minute -rpm-), and orbital diameter (25.4 and 19 mm). The analysis of the oxygen transfer was done in terms of the measured volumetric mass transfer coefficient (kLa) and of the hydrodynamics in terms of power input per unit volume of liquid (P/V), the turbulent eddy length scale measured by the Kolmogorov's microscale of turbulence, the energy dissipation rate, the average shear stress, and the shear rate. Though almost all measured kinetic and stoichiometric parameters remained unchanged, mAb titer included, significant differences were found in maximum cell concentration, 10-45% higher in conditions with lower values of kLa and P/V. Changes in glucose metabolism contributing to qP were only shown in the higher producer cell line. Non-lethal responses to elevated oxygen transfer and shear stress might be present and must be considered when evaluating CHO cell cultures in shake flasks.
