Summary: This study compared the use of the ECPS powered stapler to manual circular staplers in left-sided colorectal anastomosis, finding that the ECPS device may have a positive impact on reducing the risk of anastomotic leakage. Further multicenter controlled trials are needed to provide stronger evidence for changing clinical practice.

Summary: This observational cohort study compared the costs and characteristics of wound complications after hospital discharge with those identified during hospitalization. Of the patients undergoing colorectal surgery, postdischarge wound complications were found to have lower costs at 30 and 90 days post-surgery compared to in-hospital complications, with almost half of them managed as outpatients.

Summary: The purpose of this study is to assess the impact of Echelon Circular(& TRADE;) powered stapler (PCS) on left-sided colorectal anastomotic leaks and compare it to conventional circular staplers (CCS). A cohort study was conducted on 552 patients who underwent laparoscopic colorectal resection and anastomosis, and the results showed that the powered circular stapler did not have an impact on anastomotic leaks, but it could affect the bleeding rate at the anastomotic site.

Summary: Male sex, incomplete intestinal obstruction, and using a 32-mm circular stapler during surgery were identified as independent risk factors for anastomotic leakage after laparoscopic low anterior resection for rectal cancer. Choosing a smaller-diameter circular stapler may reduce the occurrence of anastomotic leakage without increasing the incidence of stenosis in this patient population.

Summary: This study observed patients undergoing hepatectomy for colorectal metastases and found that there is a risk of thrombosis before the surgery, which is further increased by the hepatectomy. Based on the results, it is suggested that chemical thromboprophylaxis should be considered early in the patient pathway.

Summary: This study compared the incidence of anastomotic leakage between a conventional manual circular stapler (MCS) and the ECHELON CIRCULAR™ Powered Stapler (ECPS) in patients with left-sided colorectal cancer who underwent anastomosis. The results showed that the incidence of anastomotic leakage was significantly lower in the ECPS group compared to the MCS group. Therefore, the ECPS has the potential to reduce the rate of anastomotic leakage in left-sided colorectal surgery.

Summary: The objective of this study was to examine whether variation in failure to rescue (FTR) contributes to differences in mortality between centres and over time for patients undergoing colorectal cancer surgery. The study found that high-mortality centres were characterized by higher rates of FTR and postoperative complications, and the improvement in FTR over the past decade was the main factor driving the decrease in mortality.

Summary: This study investigated the association between the position of the stapler spike relative to the rectal transection line and anastomotic integrity in colorectal anastomoses. The results showed that the presence or absence of crossing staple lines had a significant impact on anastomotic integrity.

Summary: A meta-analysis comparing linear stapling and circular stapling for anastomosis after laparoscopic gastric surgery found that linear stapling resulted in lower incidence of overall morbidity, anastomotic complications, anastomotic stricture, bleeding, and wound infection, indicating that it is a safer and more efficient technique.

Summary: This paper examines a multi-hop cognitive radio (CR) enabled device-to-device (D2D) network that extends communication from a functional area to a non-functional area. D2D users utilize cellular user bands in cognitive mode for information transmission while ensuring service quality for cellular users. The outage probability of the network is derived and the impact of noise power uncertainty is also investigated. Throughput and energy efficiency expressions are developed, taking into account collision constraint and noise uncertainty. Various network parameters are considered, including collision probability, sensing time, and noise uncertainty, and it is observed that collision constraint and noise uncertainty have significant impacts on network performance. A simulation test-bed is developed to verify the analytical results.

Summary: With the progress in information technology and wireless technologies, NOMA has emerged as a promising technique for connecting IoT devices. In this paper, the outage performance of relay-assisted signal transmission with NOMA as a multiple access scheme is analyzed. The results show that the system's outage performance depends on the transmit SNR of users, and serving multiple users in NOMA degrades the outage performance in higher SNR regime.

Summary: This article explores the use of unmanned aerial vehicles (UAVs) in downlink NOMA networks to improve connectivity in 5G networks. The outage probability for both orthogonal multiple access (OMA) and NOMA is derived to determine if communication from the ground node to the destination node is possible. Additionally, power allocation is optimized to maximize energy efficiency, and a multiple interference cancellation scheme is used to enhance signal quality at the receiving end.

Summary: This paper analyzes the functional estimates of short duration mean power generation and associated variability at a site near the port town in peninsular India, where a proposed installation of two-body floating heave buoy wave energy convertor is supposed to be carried out. The study focuses on the application of the concept of capture width function for estimating power output and variability of WEC units that capture energy through oscillatory dynamics of masses, as well as the impact of multi-mode power capture on short duration output power variability. The comparison with the Pelamis WEC shows that it is a more competitive alternative in terms of output power variability compared to floating heave buoys.

Summary: This paper analyzes the secrecy performance of a cooperative communication network, where the source transmits information to the destination via multiple relays with multiple antennas, and an eavesdropper can only eavesdrop on the relay. Due to deep fading and shadowing, there is no direct link between the source and the destination, and the signal transmission is completed in two phases: broadcasting and relaying. Each relay follows the decode and forward protocol and receives the information signal with multiple antennas. A selected relay harvests energy from the received signals and transmits both information and jamming signals. The results show that a selected relay can harvest 0.3706 joules of energy with a 5-antenna array when the source transmits the information signal with 5 dBW power. It is also observed that the performance improves by 99.24% when using a 4-antenna system compared to a 2-antenna system when the secrecy threshold is 1 bit/s/Hz. The secrecy performance is measured using the secrecy outage probability (SOP), and a closed-form expression of the SOP is derived and verified with simulation results.

Summary: Increased exportation of forest harvest residues due to higher demand for woody biomass has led to soil mineral resource depletion and negative effects on tree nutrition and growth. Removing harvest residues and litter significantly reduces tree growth and wood density in young beech and oak forest stands.
