Case report: Drainage tube penetrating anastomosis as a rare cause for long-term nonunion of esophagogastric anastomosis in neck

Anastomotic leakage is a life-threatening complication for esophageal cancer patients who received McKeown esophagectomy. Cervical drainage tube penetrating anastomosis is a rare but noteworthy cause of long-term nonunion of esophagogastric anastomosis. Here we reported two cases of esophageal cancer patients who received McKeown esophagectomy. The first case acquired the anastomotic leakage on postoperative day (POD) 7, and lasted for 56 days. The cervical drainage tube was removed at POD 38, and the leakage healed in 25 days. The second case acquired the anastomotic leakage on POD 8 and lasted for 95 days. The cervical drainage tube was removed at POD 57, and the leakage healed in 46 days. The two cases demonstrated the duration-prolonging effect of drainage tube penetrating anastomosis, which should not be overlooked in clinical practice. We suggested paying attention to the duration of leakage, the drainage fluids amounts and characteristics, and the imaging manifestations to help diagnose. If the cervical drainage tube penetrated the anastomosis, the tube should be eliminated as soon.

Role of civil society in health care: Mechanisms for realizing universal health coverage in vulnerable communities of India

The role of civil society as a partner in the delivery of primary health care is well-established. The pandemic placed a great burden on the existing public health system and civil society stepped forward not only to help the vulnerable population to mitigate challenges that subsequently arose but also to fill the gaps the pandemic exposed in India's health care system. The objective of this paper is to provide mechanisms for realizing universal health coverage by strengthening primary health care from the perspective of civil society. The paper uses examples of efforts of SNEHA, a non-profit organization working on the health of women and children in informal settlements of Mumbai and other civil society organizations working with vulnerable or hard-to-reach populations. We use existing literature, field data, reports and published work over the years. We find that civil society helps the health system to connect with difficult-to-reach populations and achieve wider coverage. They can also build the capacity of frontline staff in the public systems in formal and informal ways. They can recommend ways to change the attitudes and motivations of these workers. Civil society organizations with their close connection with the community can play the part of a “gap-filler” and data messenger. Finally, they can refer people to appropriate health facilities minimizing out-of-pocket expenditure on health.
An Atlas of Far-Ultraviolet Spectra of Wolf-Rayet Stars from the FUSE Satellite

We present an atlas of far-ultraviolet spectra of 21 Wolf-Rayet (WR) stars in the Galaxy and Large and Small Magellanic Clouds, secured with the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite. The data cover the wavelength range of 912-1190 Å at a spectral resolution of 0.1 Å and span examples of most subtypes in the WN and WC sequences. We discuss the FUV spectral morphology of the different WR sequences, emphasizing the wide range of ions and chemical species exhibiting well-developed P Cygni profiles and emission lines in this wavelength range. For WN stars the relative strengths of C IV/C III, N III/N II, P V/P IV, and Si IV/Si III show a decrease in strength of the high ions from WN3 to WN11 complemented by an increase in the lower ions at later types. The "super ions" of O VI and S VI are considered photoionized wind features for WN3-WN6 stars, probably the result of Auger ionization in WN7-WN9 stars, and probably absent at WN10-WN11. The WN5h star Sk 41 in the SMC shows relatively weaker features, which can be ascribed to the effects of a global galaxy metal deficiency. For the WC stars, a similar pattern of wind ionization-linked strengths in the emissions and P Cygni profiles is present, particularly evident in the relative strengths of lines in P V, S IV, Si IV, and Si III. O VI, and S VI features are only seen in the earliest WC subtypes. The high carbon abundance in WC stars is reflected by the presence of strong C IV and C III lines throughout the sequence. We present new estimates of the wind terminal velocities from measurements of saturated absorption components observed in a wide range of I.P. species. Considerable revisions to v∞ for the WN3 and WN5 (SMC) stars in our sample and, in particular for the WN10 and WN11 stars are found. The latter make use of the unique availability of the N II resonance line in the FUSE waveband.
Application Progress Of Auxiliary Incision Based On Open Laparoscopy In The Treatment Of Colorectal Cancer

The incidence of colorectal cancer is constantly increasing. With the improvement of residents' health need and the continuous development of surgery, more and more patients with colorectal cancer have a history of abdominal surgery. Complex abdominal adhesions put forward higher requirements for surgeons. The use of Veress puncture needle to establish pneumoperitoneum in laparoscopic-assisted colorectal cancer surgery leads to an increased incidence of puncture side injury.Open laparoscopy is an effective method to reduce puncture damages, but there are still some limitations. Combined with the fact that most laparoscopic assisted colorectal cancer operations require auxiliary incisions, advance incision seems to be a reasonable solution. Its application is not limited to patients with previous surgical history, but also can be routinely applied to all patients with colorectal cancer. Its efficacy and safety need to be verified by further clinical studies.
Research of stationary partitions in nonstationary processes by measurement of spectral distance with the help of nondyadic Malvar's decomposition

In this article, we propose a simple algorithm allowing the research of stationary partitions in locally stationary processes, by use of adapted local bases like the local DCT or the short-time Fourier transform. The algorithm aims at finding some windows of which width is adapted to the rate of change in the spectrum. A similar approach was proposed by Adak (1995), who detected changes over time in the spectra of the process to select a data-dependent window size. The same principle is used in our algorithm, with a more robust estimation of the difference in spectra than Adak. After denoising of the periodogram with the help of the undecimated wavelet transform, we consider the "symmetrical case" in the best partition selection method. A post-treatment permits us to deal with the nonuniform partitions.
The Design Space of the Auditory Representation of Objects and Their Behaviours in Virtual Reality for Blind People

As virtual reality (VR) is typically designed in terms of visual experience, it poses major challenges for blind people to understand and interact with the environment. To address this, we propose a design space to explore how to augment objects and their behaviours in VR with a nonvisual audio representation. It intends to support designers in creating accessible experiences by explicitly considering alternative representations to visual feedback. To demonstrate its potential, we recruited 16 blind users and explored the design space under two scenarios in the context of boxing: understanding the location of objects (the opponent's defensive stance) and their movement (opponent's punches). We found that the design space enables the exploration of multiple engaging approaches for the auditory representation of virtual objects. Our findings depicted shared preferences but no one-size-fits-all solution, suggesting the need to understand the consequences of each design choice and their impact on the individual user experience.
Roles of Local Soluble Factors in Maintaining the Growth Plate: An Update

The growth plate is a cartilaginous tissue found at the ends of growing long bones, which contributes to the lengthening of bones during development. This unique structure contains at least three distinctive layers, including resting, proliferative, and hypertrophic chondrocyte zones, maintained by a complex regulatory network. Due to its soft tissue nature, the growth plate is the most susceptible tissue of the growing skeleton to injury in childhood. Although most growth plate damage in fractures can heal, some damage can result in growth arrest or disorder, impairing leg length and resulting in deformity. In this review, we re-visit previously established knowledge about the regulatory network that maintains the growth plate and integrate current research displaying the most recent progress. Next, we highlight local secretary factors, such as Wnt, Indian hedgehog (Ihh), and parathyroid hormone-related peptide (PTHrP), and dissect their roles and interactions in maintaining cell function and phenotype in different zones. Lastly, we discuss future research topics that can further our understanding of this unique tissue. Given the unmet need to engineer the growth plate, we also discuss the potential of creating particular patterns of soluble factors and generating them in vitro.
A note on the location of the stagnation point in the magnetosheath flow

Observational and theoretical investigations indicate that the shape of the magnetosphere is nearly symmetric about the plane defined by the aberrated solar wind velocity and the earth's magnetic dipole axis. Nevertheless, many phenomena such as magnetic pulsations and geomagnetic activity seem to indicate that the effective solar wind arrival direction is perhaps 15/sup 0/ to the dawn side of noon. This apparent paradox may have a simple resolution since it can be shown that the location of the stagnation point in the magnetosheath flow is shifted towards dawn by MHD effects not included in the simple gasdynamic model of the solar wind interaction. The shape of the magnetosphere is little affected by the inclusion of these MHD effects. However, the size of the stagnation point shift is very sensitive to the Alfven Mach number and can only account for the largest reported shifts (approx.15/sup 0/) at low Mach numbers (< or approx. =3.5).
Self-assembling fluidic machines

This letter describes dynamic self-assembly of two-component rotors floating at the interface between liquid and air into simple, reconfigurable mechanical systems (“machines”). The rotors are powered by an external, rotating magnetic field, and their positions within the interface are controlled by: (i) repulsive hydrodynamic interactions between them and (ii) by localized magnetic fields produced by an array of small electromagnets located below the plane of the interface. The mechanical functions of the machines depend on the spatiotemporal sequence of activation of the electromagnets.
Theory of Three-Dimensional Orderings of Charge-Density Waves in 1T-TaX2 (X: S, Se)

Three-dimensional structures of charge-density waves in 1T-Ta dichalcogenides are studied on the basis of a phenomenological free energy, in which interlayer couplings up to the second neighbor layer are considered. Special attention is paid to the commensurate (C) and striped discommensurate (DC) states. Several stable stackings are obtained both in the C and striped DC states, where some of them in the C states are found to be disordered. The theory is applied to 1T-TaS 2 , on which Tanda et al. have made an X-ray experiment recently. To explain the experimental data a novel model is proposed for the C phase. In addition the structure of the new phase appearing between the C and nearly C phases is discussed from the standpoint of the striped DC state.
Cybersickness, Cognition, & Motor Skills: The Effects of Music, Gender, and Gaming Experience

Recent research has attempted to identify methods to mitigate cybersickness and examine its aftereffects. In this direction, this paper examines the effects of cybersickness on cognitive, motor, and reading performance in VR. Also, this paper evaluates the mitigating effects of music on cybersickness, as well as the role of gender, and the computing, VR, and gaming experience of the user. This paper reports two studies. In the 1st study, 92 participants selected the music tracks considered most calming (low valence) or joyful (high valence) to be used in the 2nd study. In the 2nd study, 39 participants performed an assessment four times, once before the rides (baseline), and then once after each ride (3 rides). In each ride either Calming, or Joyful, or No Music was played. During each ride, linear and angular accelerations took place to induce cybersickness in the participants. In each assessment, while immersed in VR, the participants evaluated their cybersickness symptomatology and performed a verbal working memory task, a visuospatial working memory task, and a psychomotor task. While responding to the cybersickness questionnaire (3D UI), eye-tracking was conducted to measure reading time and pupillometry. The results showed that Joyful and Calming music substantially decreased the intensity of nausea-related symptoms. However, only Joyful music significantly decreased the overall cybersickness intensity. Importantly, cybersickness was found to decrease verbal working memory performance and pupil size. Also, it significantly decelerated psychomotor (reaction time) and reading abilities. Higher gaming experience was associated with lower cybersickness. When controlling for gaming experience, there were no significant differences between female and male participants in terms of cybersickness. The outcomes indicated the efficiency of music in mitigating cybersickness, the important role of gaming experience in cybersickness, and the significant effects of cybersickness on pupil size, cognition, psychomotor skills, and reading ability.
High-Quality Energetic Proton Beams from an Intense Laser-Plasma Interaction with a Micro-Structured Slab Target

High-quality energetic proton-beam generation from the interaction of a high-intensity short-pulse laser with an overdense plasma slab has been studied by using a two-dimensional, fully electromagnetic and relativistic particle-in-cell simulation. The collimation and the beam divergence of the accelerated protons are expected to strongly depend on the spatial coupling between the laser pulse and the target plasma. In this work, with a proper micro-modification of the target structure, improved beam quality, including the collimation, the forward directionality and the beam divergence, are clearly demonstrated. For a detailed analysis, the relativistic momentum distribution, the spatial density map and the angular distribution of the accelerated protons are considered.
Social Media as Mobilizer and Demobilizer: Evidence From Taiwan

This study examines the effect of social media use on voter turnout. Given that different social media platforms provide different types of content and people use different social media platforms for different purposes, this study argues that there exist differentiated relationships between different types of social media and voter turnout. Using an original panel data set for the 2018 Taipei mayoral election in Taiwan, this study evaluates how five different types of social media—Facebook, LINE, YouTube, Instagram, and PTT—influence voter participation. The empirical results show that people with frequent use of Facebook and PTT are more likely to vote, whereas the frequent use of YouTube and Instagram decreases voter turnout. Furthermore, the use of LINE has no influence on voter participation. Overall, this study reveals that different types of social media exert heterogeneous effects on voter turnout and suggests that when it comes to the influence of social media on voter turnout, we should pay attention to not only the frequency of social media use but also the purpose of social media use.
Inverse scattering of H/sub z/ waves using subscatterer T-matrices

The inverse scattering problem for H/sub z/ waves impinging on two-dimensional dielectric objects is solved. An inverse scattering algorithm called local shape function (LSF) imaging that abandons the standard integral equation model for a T-matrix model is described. With this algorithm, larger objects or higher dielectric contrasts can be resolved compared to the Born-type iterative methods. The improvement in the LSF algorithm arises because the model has a better approximation for the internal field. For simulation, three smooth dielectric profiles have been inverted with the distorted Born iterative method and the LSF algorithm. As expected, the LSF algorithm converges for a larger range of contrasts than the Born-type iterative methods, as large as 5:1 contrasts. <<ETX>>
Visualisation on supersonic flow over backward-facing step with or without roughness

At Mach number 3.4, visualisation experiments of flow over backward-facing step (BFS) with or without roughness band attached on upstream wall are carried out via traditional schlieren and newly developed nano-tracer-based planar laser scattering (NPLS). The time-averaged flow characteristic of the reattachment region and the instantaneous rich structures of the redeveloping boundary layer in the steamwise-normal plane are both revealed. Additionally, top views in the different planes (y/h = 0.67, 1.00, 1.33, 1.67, 2.00) are imaged with a resolution of 0.064 mm/pixel. By contrasting the NPLS images at different times, the unsteady evolution characteristic of the coherent vortices in the redeveloping boundary layer was discussed. Static wall pressure is measured by a micro-pressure scanning system. The incipient formation positions are pointed out statistically. Without roughness, the longitudinal structures with scales of 1.0h and 1.2h form later and distribute in a longer region compared to that with roughness. Fractal analysis is applied and the averaged fractal dimensions of the overall and sectional flow structures are calculated. If roughness is adopted, the fractal dimension will be larger and the turning point in the sectional fractal dimensions is earlier. However, the dimension tends to be one coincided value in the farther downstream.
Linkages between rapid climate variability and deep-sea benthic foraminifera in the deep Subantarctic South Atlantic during the last 95 kyr

We present a high-resolution record of benthic foraminifera fauna from a sediment core retrieved from the South Cape Basin (Subantarctic South Atlantic) spanning the last glacial cycle (95 kyr). Information provided by benthic foraminiferal assemblages together with paleoclimate proxies from the same core allow us to interpret changes in the style of primary production (episodic versus sustained) in relation to abrupt climate oscillations. Our results indicate that fluctuations in the abundance of the phytodetritus-related species, Epistominella exigua, are concomitant with millennial-scale high-latitude climate perturbations. Episodic phytoplankton blooms increased during a negative mode of the bipolar seesaw, irrespective of the magnitude of the perturbation (i.e., Heinrich stadial versus non-Heinrich stadial events). We provide a hypothesis linking the frequency and intensity of these events to atmospheric perturbations, interhemispheric climate variability, and millennial-scale changes in atmospheric CO2. A notable exception to the overall pattern is the generally high abundance of E. exigua across the globally synchronous onset of glacial marine oxygen isotope stage (MIS) 4, a period generally characterized by increased dustiness and low-quality organic carbon as inferred by the percentage of the nonphytodetritus species. This highlights the special characteristics governing the onset of MIS 4 in the Subantarctic.
Fine-Structure Excitation of O I and C I by Impact with Atomic Hydrogen

Using accurate interaction potentials, we perform refined calculations of rate coefficients for the fine-structure excitations in collisions of O(3P) and C(3P) with atomic hydrogen. The results are presented in the form of analytical functions approximating the rate coefficients over a wide range of temperatures. We examine the sensitivity of the collision dynamics to variations of the interaction potentials and the couplings to electronically excited states.
Is lobectomy an appropriate surgical strategy for nodular goiter in endemic areas?

Introduction: Thyroid nodules are evaluated by fine-needle aspiration biopsy (FNAB) according to their radiologic characteristics. International guidelines recommend lobectomy according to the size of the nodules and FNAB results. The aim of this study is to assess whether lobectomy is one of the treatment choices in endemic areas. Methods: Patients who underwent lobectomy between January 2013 and September 2017 were studied retrospectively. Patients’ demographic features, thyroid hormone levels, medications, FNAB results before the surgery, lobectomy indications, ultrasonographic features, final pathologies, and secondary surgical interventions were recorded. Results: Data of 388 patients who underwent lobectomy were examined. As patients were classified according to their FNAB results, all categories had higher malignancy rates than expected in the final pathology results. One hundred and eighteen (30.4%) patients had undergone completion thyroidectomy. The final pathology of the completion thyroidectomy samples showed 24.07% (n=26) malignancy. Discussion and Conclusion: FNAB is the gold standard for the malignancy risks in thyroid nodules in all guidelines. In endemic areas, this classification system may be inadequate. Two-staged thyroid surgery is becoming more popular. In our series, 30.4% of patients had undergone completion thyroidectomy according to their final pathology results. We need to add newer sights to guidelines for endemic areas.
