Intussusception of Gastrojejunostomy After Pancreatoduodenectomy With Billroth II Reconstruction

Gastrojejunal anastomosis or gastrojejunostomy (GJ) is a surgical procedure used for allowing gastric emptying, especially in cases where complex reconstructions are needed. One of the less common complications but one of the most relevant in morbidity is the intussusception of the GJ. It requires a high index of suspicion, preoperative optimization of the patient, diagnostic corroboration, and identification of associated complications with the use of contrasted imaging. It was described for the first time by Bozzi in 1914; currently, multiple cases have been described in the literature, being more frequent in bariatric surgeries and reconstructions after distal gastrectomy. In hepatopancreaticobiliary surgery, it is an even uncommon complication. We present the case of a 60-year-old man with intussusception of the efferent loop of the GJ after a pylorus-preserving pancreatoduodenectomy with a Billroth II reconstruction in the setting of malignancy of the extrahepatic bile duct along with our emergency surgical treatment.

Distributed Dynamic Event-Triggered Resilient Control for AC Microgrids Under FDI Attacks

In this paper, we investigate the distributed resilient control problem of voltage and frequency restoration in AC microgrids (MGs) subject to false data injection (FDI) attacks under event-triggered communication. To solve the problem, new distributed dynamic event-triggered <inline-formula> <tex-math notation="LaTeX">$k$ </tex-math></inline-formula>-step attack observers are primarily designed for the accurate estimation of attacks while avoiding continuous communication. Based on the observer state, cooperative resilient controllers for voltage and frequency restoration are proposed, and the convergence of the voltage and frequency of the AC MGs as well as the exclusion of Zeno behavior are proved theoretically. Different from the existing event-triggered resilient control methods in AC MGs subject to unknown bounded FDI attacks, the developed distributed dynamic event-triggered based <inline-formula> <tex-math notation="LaTeX">$k$ </tex-math></inline-formula>-step attack observers and cooperative resilient controllers can guarantee accurate observation and compensation for FDI attacks. Finally, experimental tests are carried out to validate the effectiveness of the proposed control method, which demonstrates great resilience in maintaining stable operations under FDI attacks and represents a dramatic reduction in communication costs.
Message Passing Receivers for Generalized Media-Based Modulation Signals

We consider generalized media-based modulation (GMBM), where transmit antennas and radio frequency (RF) mirrors (which are parasitic elements placed near the transmit antennas as digitally controlled scatterers) are indexed simultaneously to convey information bits. We develop low complexity receiver algorithms for the detection of high-rate, large-dimension GMBM signals. Message passing-based detection is a promising low-complexity approach. The elements in a GMBM transmit vector are interdependent. Message passing with a multi-layering approach is proposed to take care of this dependency. The proposed multi-layering approach decouples the dependencies through the addition of new layers and constraints that account for the antenna activation and RF mirror activation patterns. The proposed message passing detection with multi-layering, termed as multi-layered message passing detection, is shown to outperform message passing detection without multi-layering and constraints. In addition to exploiting multi-layering, the channel hardening property of large MIMO channels is exploited for GMBM signal detection and channel estimation. The algorithm based on this approach is termed as multi-layered channel hardening-exploiting message passing algorithm. The proposed algorithms scale well in complexity and achieve good bit error performance in high-rate, large-dimension GMBM systems.
The neural correlates of perceived social support and its relationship to psychological well-being

Introduction Perceived social support is considered to play a significant role in promoting individuals’ health and well-being, and yet the neural correlates of perceived social support were not fully understood. An exploration of the neural correlates of individual differences in the SPS can help us to gain more comprehensive understanding about the neural correlates of perceived social support. What’s more, our study will explore the relationship among perceived social support, brain regions, and psychological well-being, which may provide new insights into the neural correlates underlying the relationship between perceived social support and psychological well-being from the perspective of cognitive neuroscience. Methods Herein, we used the Social Provisions Scale to assess individuals’ perceived social support, and magnetic resonance imaging was used to measure the gray matter (GM) volume of the whole brain. What’s more, we also measured psychological well-being using the Psychological Well-Being Scale, and mediation analysis was used to explore the relationship among perceived social support, brain regions, and psychological well-being. Results The voxel-based morphometry analysis of the whole brain revealed that perceived social support was positively correlated with GM volume of the left middle temporal gyrus (MTG). The finding indicated that a person with greater GM volume in the left MTG perceived more social support. More importantly, the left MTG GM volume observed above was also associated with psychological well-being, and the link between the two was mediated by perceived social support. Discussion These results revealed the importance of MTG for perceived social support and psychological well-being, and also suggested that perceived social support might explain the relationship between MTG and psychological well-being.
Wave-Based Outcomes Comparison of Hospitalized COVID-19 Patients: A Retrospective Multicenter Cohort Study From Rural Appalachia

Background: There has been little to no characterization of the pandemic’s effects on rural Central Appalachia, in which health disparities in the pre-COVID-19 era have historically plagued. This is the first study to compare wave-based differences in outcomes of hospitalized patients with COVID-19 in the rural Appalachian region. This study aims to provide a more comprehensive understanding of the effects of the COVID-19 pandemic on large rural communities and Appalachia. Methods: This is a retrospective cohort study of hospitalized patients with COVID-19 between April 2020 and June 2022, which includes 13 Appalachian Regional Healthcare (ARH) hospitals. The primary outcome of the study was in-hospital mortality. Secondary outcomes included intensive care unit (ICU) stay, need for mechanical ventilation, length of hospital stay, 1-30-day re-admittance, 30-60-day re-admittance, and thromboembolism incidence risk. Results: The second wave of infections during the pandemic demonstrated the highest mortality with higher odds of affecting younger patients. The third wave demonstrated similar mortality to the first wave. Elderly patients and patients with chronic morbidities demonstrated the highest mortality and morbidity and the highest requirement for mechanical ventilation across the three waves. Vaccination lowered the odds of mechanical ventilation and ICU stay. Conclusions: This study comprehensively characterizes the impact of the COVID-19 pandemic in rural regions of Appalachian Kentucky and West Virginia. Future studies comparing differences between rural and urban geographies may be able to distinguish whether the disparities in these regions played a role in the impact on residents.
Role of Perturbated Hemostasis in MASLD and Its Correlation with Adipokines

The prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) continues to rise, making it one of the most prevalent chronic liver disorders. MASLD encompasses a range of liver pathologies, from simple steatosis to metabolic dysfunction-associated steatohepatitis (MASH) with inflammation, hepatocyte damage, and fibrosis. Interestingly, the liver exhibits close intercommunication with fatty tissue. In fact, adipose tissue could contribute to the etiology and advancement of MASLD, acting as an endocrine organ that releases several hormones and cytokines, with the adipokines assuming a pivotal role. The levels of adipokines in the blood are altered in people with MASLD, and recent research has shed light on the crucial role played by adipokines in regulating energy expenditure, inflammation, and fibrosis in MASLD. However, MASLD disease is a multifaceted condition that affects various aspects of health beyond liver function, including its impact on hemostasis. The alterations in coagulation mechanisms and endothelial and platelet functions may play a role in the increased vulnerability and severity of MASLD. Therefore, more attention is being given to imbalanced adipokines as causative agents in causing disturbances in hemostasis in MASLD. Metabolic inflammation and hepatic injury are fundamental components of MASLD, and the interrelation between these biological components and the hemostasis pathway is delineated by reciprocal influences, as well as the induction of alterations. Adipokines have the potential to serve as the shared elements within this complex interrelationship. The objective of this review is to thoroughly examine the existing scientific knowledge on the impairment of hemostasis in MASLD and its connection with adipokines, with the aim of enhancing our comprehension of the disease.
Longitudinal Control for Cruise Control Features in Vehicle Automation

This research focuses on longitudinal control methods implemented in Cruise Control (CC) and Adaptive Cruise Control (ACC) systems, as well as the mechanism for switching between these two modes. Two primary longitudinal control methods are examined: Constant Space Headway Control, which maintains a constant distance between vehicles, and Constant Time Headway Control, which maintains a constant time gap between vehicles. The noteworthy feature of this research focuses on incorporating a switching mechanism between Cruise Control and Adaptive Cruise Control through the utilization of the virtual target method.
An Outphasing Architecture Based on Parallel Radio Frequency–Pulse Width Modulation Method for All-Digital Transmitter

For the existing outphasing architectures of an all-digital transmitter (ADTx), the required sampling rate of the signal is too high, which increases the difficulty of digital radio frequency pulse width modulation (RF-PWM) processing. In this paper, we present an outphasing architecture based on the parallel RF-PWM method for an ADTx. Through polyphase interpolation, two baseband outphasing signals are divided into multiple low-rate signals to process simultaneously. The parallel outphasing signals are modulated and encoded to obtain 1-bit parallel signals, which are, respectively, transmitted to multigigabit transceivers (MGTs) to generate two two-level high-speed pulses with different phases. Finally, a three-level high-speed pulse is synthesized and amplified through the switching power amplifier. Through this parallel scheme, the sampling rate of digital RF-PWM signal processing is effectively reduced. Moreover, to explore a pulse encoding method, the outphasing architecture is combined with a zero-crossing comparison through an angle calculation and quadrant judgment, which simplifies the modulation and encoding process. In addition, the impact of the sub-filter order and the number of parallel paths on system performance is analyzed. The simulation results show that for a 16QAM signal with a baseband bandwidth of 20 MHz and a carrier frequency of 200 MHz, the adjacent channel power ratio (ACPR) is below −45 dBc and the error vector magnitude (EVM) is below 1% in the proposed scheme.
Mobile Apps for COVID-19: A Systematic Review of Reviews

Background: One measure national governments took to react to the acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) pandemic was mobile applications (apps). This study aims to provide a high-level overview of published reviews of mobile apps used in association with coronavirus disease 19 (COVID-19), examine factors that contributed to the success of these apps, and provide data for further research into this topic. Methods: We conducted a systematic review of reviews (also referred to as an umbrella review) and searched two databases, Medline and Embase, for peer-reviewed reviews of COVID-19 mobile apps that were written in English and published between January 1st 2020 and April 25th 2022. Results: Out of the initial 17,611 studies, 24 studies were eligible for the analysis. Publication dates ranged from May 2020 to January 2022. In total, 54% (n = 13) of the studies were published in 2021, and 33% (n = 8) were published in 2020. Most reviews included in our review of reviews analyzed apps from the USA, the UK, and India. Apps from most of the African and Middle and South American countries were not analyzed in the reviews included in our study. Categorization resulted in four clusters (app overview, privacy and security, MARS rating, and miscellaneous). Conclusions: Our study provides a high-level overview of 24 reviews of apps for COVID-19, identifies factors that contributed to the success of these apps, and identifies a gap in the current literature. The study provides data for further analyses and further research.
Conserving Marine Forests: Assessing the Effectiveness of a Marine Protected Area for Cystoseira sensu lato Populations in the Central Mediterranean Sea

Marine Protected Areas (MPAs) are vital for biodiversity conservation, yet their effectiveness in preserving foundation seaweeds remains understudied. This study investigates the diversity and distribution of Cystoseira sensu lato (including Cystoseira, Ericaria, and Gongolaria, hereafter referred to as Cystoseira s.l.) populations in an MPA located in the central Mediterranean Sea, comparing them with those in two unprotected sites. We hypothesized MPA Cystoseira s.l. populations would display higher diversity and structure compared to outside unprotected sites. Results revealed a total of 19 Cystoseira s.l. species at depths of 0–20 m, with the MPA exhibiting a higher diversity than unprotected sites. Thus, MPAs can play a crucial role in fostering the diversity of Cystoseira s.l. populations. However, no significant differences were observed among the MPA’s protection zones, raising questions about the zoning effectiveness. Additionally, our survey uncovered a substantial presence of non-indigenous seaweeds within the MPA. In conclusions, while MPAs improved Cystoseira s.l. diversity compared to unprotected sites, the varying efficacy of protection within MPA zones suggested a necessity for site-specific conservation strategies. The presence of non-indigenous seaweeds emphasizes ongoing challenges. This study provides a baseline for understanding Cystoseira s.l. population dynamics, crucial for future monitoring and conservation efforts in the face of global change.
Miniaturization of DGS Filter Based on Matryoshka Geometry Using Calcium Cobaltite Ceramic

This paper introduces the use of calcium cobaltite ceramic of composition Ca3Co4O9, C349, for miniaturization of a defected-ground-structure (DGS) filter based on matryoshka geometry. Initially applied to frequency selective surfaces, matryoshka geometry has been successfully applied to filters and sensors. Recently, this geometry has been used in a DGS filter achieving a decrease in the resonant frequency of up to 47.2%, when compared to traditional geometries such as dumbbells. Despite this result being quite interesting, the use of a small calcium cobaltite ceramic disk, practically without increasing the original area occupied by the DGS, further reduces the resonant frequency, achieving approximately 43.0% of the DGS-matryoshka geometry without the ceramic disk, which corresponds to an occupied area of approximately $0.062\lambda_{0} {\times}0.062\lambda_{0}$. Furthermore, for the same DGS-matryoshka geometry, different positions of the ceramic disk can be used to obtain different resonant frequencies. Numerical and experimental results are presented, verifying a good agreement.
Control of the Dust Vertical Distribution over Western Africa by Convection and Scavenging

Saharan dust represents more than 50% of the total desert dust emitted around the globe and its radiative effect significantly affects the atmospheric circulation at a continental scale. Previous studies on dust vertical distribution and the Saharan Air Layer (SAL) showed some shortcomings that could be attributed to imperfect representation of the effects of deep convection and scavenging. The authors investigate here the role of deep convective transport and scavenging on the vertical distribution of mineral dust over Western Africa. Using multi-year (2006–2010) simulations performed with the variable-resolution (zoomed) version of the LMDZ climate model. Simulations are compared with aerosol amounts recorded by the Aerosol Robotic Network (AERONET) and with vertical profiles of the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) measurements. LMDZ allows a thorough examination of the respective roles of deep convective transport, convective and stratiform scavenging, boundary layer transport, and advection processes on the vertical mineral dust distribution over Western Africa. The comparison of simulated dust Aerosol Optical Depth (AOD) and distribution with measurements suggest that scavenging in deep convection and subsequent re-evaporation of dusty rainfall in the lower troposphere are critical processes for explaining the vertical distribution of desert dust. These processes play a key role in maintaining a well-defined dust layer with a sharp transition at the top of the SAL and in establishing the seasonal cycle of dust distribution. This vertical distribution is further reshaped offshore in the Inter-Tropical Convergence Zone (ITCZ) over the Atlantic Ocean by marine boundary layer turbulent and convective transport and wet deposition at the surface.
SMART PHONE USE AND ITS EFFECT ON QUALITY OF SLEEP IN MEDICAL STUDENTS

Background: Life without mobile phone is difficult to imagine. With the advent of “smart phone” it has emerged not only as essential means of communication, but an indispensable part of our lives. This is particularly true for adolescents, as it is primary means of socialization, entertainment, education etc. The present study was conducted to ascertain the impact of excessive use of smart phones on quality of sleep and to correlate scores of Smart phone addiction scale with scores of Sleep quality index. Materials and Methods: A cross-sectional study was conducted on 196 male and female medical undergraduate students of age between 17 and 24 years studying in a teaching hospital selected by convenient sampling method. Students who were using mobile phones more than 1 year were included in the study. Students who answered less than 50% of the questionnaires were excluded. The tools of data collection were Smart Phone Addiction Scale - Short Version (SAS-SV), and Pittsburgh Sleep Quality Index (PSQI). Spearman’s rank correlation method was used to determine the strength of relationship between smart phone addiction and quality of sleep. Result: Out of 196 subjects included in the study, 85 (43.4%) were males and 111 (56.6%) were females. Out of 196 subjects 54 (27.55%) were smart phone excessive users. Prevalence of smart phone addiction was more in males (30.6%) when compared to females (25.2%) which was not statistically significant (χ2 = 0.69, p =0.40). The mean SAS-SV score of females was slightly higher than that of males (26.69 ± 9.01 versus 25.91±8.98) which was statistically non-significant (U value = 4522, Z score = 0.495d, p = 0.617). The mean global PSQI score of all the study subjects was 4.43±2.62. The mean global PSQI score of smart phone excessive users group was slightly higher than that of smart phone non excessive users group which was statistically significant (5.15±2.51 versus 4.15±2.61, U value = 2849.5, Z score = -2.773, p = 0.005). Conclusion: Excessive use of smart phone, quality of sleep decreases by affecting the subjective sleep quality, sleep latency, sleep duration, sleep disturbance resulting in day time dysfunction and usage of sleep medication.
