Nanotechnology has enabled the delivery of small molecular drugs packaged in nanosized vesicles to the target tissues. Plant-Derived Nanoparticles (PDNPs) are vesicles with natural origin and unique properties. These nanoparticles have several advantages over synthetic exosomes and liposomes. They provide bioavailability and biodistribution of therapeutic agents when delivered into different tissues. These nanoparticles can be modified according to the specificity of their functions in target tissues. When PDNPs are internalized, they can induce stem cells proliferation, reduce colitis injury, activate intrinsic and extrinsic apoptosis pathways, and inhibit tumor growth and progression. These properties make them potential drug delivery systems in targeting diseased tissues, such as inflammatory regions and different cancers.
Randomized trials reported no difference whether induction or expectant management is performed in non-diabetic women with large for gestational age babies but no tool has been validated for the prediction of high risk cases.
Assessing the performance of different growth curves in the prediction of complications.
Data from 1066 consecutive non-diabetic women who delivered babies ≥4000 g were collected. Logistic regression analysis was used to analyze the impact of the maternal variables on instrumental delivery, shoulder dystocia (SD), perineal tears, cesarean section (CS), and postpartum hemorrhage. Intergrowth21 curves and customized Gardosi's curves were compared in terms of prediction of adverse outcomes.
Induction of labor was performed in 23.1% cases. The rate of CS was 17%. Hemorrhage, fetal distress, and SD occurred in 2%, 1.3%, and 2.7% of cases, respectively. Induction was significantly associated with instrumental delivery (
< .001), CS (
= .001), third and fourth degree perineal tears (
= .031), and post-partum hemorrhage (
= .02). The cutoff of 90th percentile according to Intergrowth21 did not show significant performance in predicting CS, while the same cutoff according to the Gardosi curves showed an OR 1.92 (CI 1.30-2.84) (
= .0009).
Gardosi curves showed a better performance in predicting the risk of CS versus Intergrowth curves. Induction is significantly associated with adverse outcome in non-diabetic women with LGA babies.

Durvalumab plus chemotherapy could significantly improve overall survival compared with chemotherapy alone in the first-line treatment of extensive-stage small-cell lung cancer (SCLC). However, its long-term economic outcomes remain unclear yet. This study aimed to evaluate the cost-effectiveness of adding durvalumab to first-line chemotherapy for extensive-stage SCLC from the perspective of the Chinese health-care system.
A decision-analytic model with 10-year horizon was developed to estimate the health and economic outcomes of adding durvalumab to first-line treatment for extensive-stage SCLC. The primary outcomes included total costs, life years (LYs), quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio (ICER). Costs and utility values were obtained from the published literature. A scenario analysis for a patient assistance program (PAP) was conducted. Sensitivity analyses were performed to explore the robustness of the model outcomes.
Durvalumab plus chemotherapy yielded additional 0.25 QALYs, with incremental costs of 76,354 USD, resulting in an ICER of 302,051 USD/QALY compared with chemotherapy alone, when PAP was available, the ICER was 192,591 USD/QALY. Sensitivity analyses confirmed the robustness of model outcomes.
Adding durvalumab to first-line chemotherapy for extensive-stage small-cell lung cancer is unlikely to be cost-effectiveness in China.

Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency is frequent inherited enzymopathy that poses potentially preventable risk for extreme hyperbilirubinemia (EHB) which can, rarely, lead to acute bilirubin encephalopathy, childhood kernicterus and death. We aimed to estimate quality adjusted life years (QALY) lost due to G6PD deficiency associated with EHB and economic costs to best estimate value of universal pre-discharge screening.
We did a cost utility analysis for US birth cohort utilizing pre-discharge screening decision tree model to estimate population burden and EHB outcomes, based on literature search and expert opinions. Employing human capital approach, we measured health benefits in terms of QALYs and economic losses. QALYs and costs were discounted at 3%; one-way sensitivity analysis was used for decision variables.
We determined for USA live births of 3.86 million in 2017, 1464 cases of EHB were estimated to be due to G6PD deficiency (CI 95%; range 1270-1656) and contributed 2 deaths (CI 95%; range 1.3-3.2) and 14 (CI 95%; range 9.1-21.5) cases of kernicterus. Over lifetime horizon, the model predicted undiscounted and discounted gains of 165 (102-252) life years; 241 (183-433) QALYs and 16 (9.9-24.5) life years; 89 (67.9-160.5) QALYs, respectively. Assuming 50% effectiveness, benefit cost ratios ranged from 0.19 to 3.42 for diverse operational settings. The cost to prevent a single case of kernicterus was $2.7 to 6.8 million per annum with cost per QALY gained at $35,946 to $89,159.
At incremental cost-effective threshold of $100,000/life year, pre-discharge screening would be expected to prove cost effective in preventing EHB related morbidities and mortality attributed to G6PD deficiency.

Given the expectations attached to citizen science in academic and science policy discourses, it is worthwhile to look at where the actual work is done. The case of South Africa, the study focus, is interesting because the country follows similar programmes as many developed countries, but has a socioeconomically and educationally more unequal society. Thus, South Africa presented a test example of whether the institutional similarities of science or socioeconomic and educational differences prevail in shaping the reality of citizen science. Results from 56 projects showed that nearly all of them were limited to data collection in life science fields and were managed largely by one university and mainly communicated within the respective science communities. This led us to conclude that the ambitious rhetoric accompanying citizen science in science policy programmes is not matched by reality.
Aortic valve sclerosis (AVSc) is defined as the thickening and calcification of aortic valve cusps, in the absence of obstruction of ventricular outflow. AVSc is linked with a clear imbalance in some trace elements.
The objective of this study was to investigate the relationship between AVSc and serum levels of iron (Fe), zinc (Zn), selenium (Se), and copper (Cu). Additionally, this research aimed to explore the clinical significance of human serum zinc, selenium, copper, and iron concentrations as a potential new biomarker for AVSc patients and to clarify the pathophysiological role in individuals at risk of developing AVSc.
The study included 40 subjects with AVSc (25% male and 75% female) who were compared with a healthy control group with the same gender ratio. AVSc was based on comprehensive echocardiographic assessments. Blood samples were taken and Zn and Cu concentrations were determined through the use of atomic absorption spectroscopy. Se was measured using an inductively coupled plasma mass sith the healthy group's valves. In the valve patients as compared, AVSc had a high prevalence of obesity, hypertension, and diabetes.
To evaluate the safety and efficacy of a new internal cold circulation bipolar radiofrequency compared with Habib-4X bipolar radiofrequency device in the resection of liver tumors.
A total of 85 patients with hepatocellular carcinoma who received radiofrequency-assisted liver resection from February 2017 to January 2020 were retrospectively enrolled in our study, in which 45 patients received the new internal cold circulation bipolar radiofrequency (New-RF) and 40 patients received Habib-4X bipolar radiofrequency (Habib-4X). Primary outcome measures were the speed of liver transection, the width of coagulation tissue, hemorrhage volume, blood transfusion rate, and operation time.
The baseline characteristics of patients in the New-RF and Habib-4X groups had no significant difference (
> 0.05). Compared to Habib-4X, the New-RF had a faster average speed of liver transection (4.81 ± 1.20 cm
/min vs 3.64 ± 1.08 cm
/min,
< 0.001), a narrower width of coagulation tissue (1.42 ± 0.23 cm
vs 1.81 ± 0.20 cm
,
< 0.001), a less operation time (55.04 ± 16.12 min vs 64.02 ± 15.09 min,
= 0.010), a lower rate of needle path bleeding (13.3% vs 35.0%,
= 0.019), and a lower carbonization rate of electrode needle (22.2% vs 77.8%,
< 0.001). Hemorrhage during the transection (85.0 ml vs 105.0 ml,
= 0.438) and hemorrhage per square centimeter (3.28 ± 0.86 ml/cm
vs 3.60 ± 1.12 ml/cm
,
= 0.141) in the New-RF group were smaller than those in Habib-4X group with no significant difference.
The new internal cold circulation bipolar radiofrequency was a safe and efficacious auxiliary device for liver resection with a faster speed of resection, lower carbonization rate of electrode needle, and more precise range of coagulation.

Lysosomes owe their function to the activity of lysosomal ion channels and transporters, which maintain concentration gradients of H+, K+, Ca2+, Na+, and Cl- across the lysosomal membrane. This review examines the contributions of lysosomal ion channels to lysosome function, showing how ion channel function is integral to degradation and autophagy, maintaining lysosomal membrane potential, controlling Ca2+ signaling, and facilitating exocytosis. Evidence of lysosome dysfunction in a variety of disease pathologies creates a need to understand how lysosomal ion channels contribute to lysosome dysfunction. For example, the loss of function of the TRPML1 Ca2+ lysosome channel in multiple lysosome storage diseases leads to lysosome dysfunction and disease pathogenesis while neurodegenerative diseases are marked by lysosome dysfunction caused by changes in ion channel activity through the TRPML1, TPC, and TMEM175 ion channels.
