Abstract
Background In lymphedema, lymphatic fluid accumulates in the interstitial space, and localized swelling appears. Lymphovenous anastomosis (LVA) is the most widely used surgery to rebuild a damaged lymphatic system; however, assessing outcome of LVA involves performing volume measurements, which provides limited information on body composition changes. Therefore, we analyzed the bioelectrical impedance analysis (BIA) parameters that can reflect the status of lymphedema patients who underwent LVA.
Methods We retrospectively reviewed records of 42 patients with unilateral lower extremity lymphedema who had LVA. We measured the perioperative BIA parameters such as extracellular water (ECW) ratio and volume as defined by the percentage of excess volume (PEV). We evaluated the relationship between the amount of change in PEV and in BIA parameters before and after surgery. We confirmed the correlation between ΔPEV and BIA parameters using Spearman's correlation.
Results Most patients included had secondary lymphedema due to cancer. Average age was 51.76 years and average body mass index was 23.27. PEV and all BIA parameters after surgery showed a significant difference (p < 0.01) compared with preoperative measurements. The ECW ratio aff/unaff showed the strongest correlation with PEV with a correlation coefficient of 0.473 (p < 0.01).
Conclusion Our findings suggest that BIA parameters, especially ECW ratio aff/unaff could reflect the status of patients with lower limb lymphedema after LVA. Appropriate use of BIA parameters may be useful in the postoperative surveillance of patients.

Resumo
Objetivos O presente estudo teve como objetivo avaliar se os parâmetros espinopélvicos pré-operatórios podem influenciar o ganho da lordose segmental após fusão intersomática lombar por via lateral de um nível.
Métodos Os seguintes parâmetros radiológicos foram medidos nos raios X: incidência pélvica, lordose lombar, versão pélvica, lordose L4S1, lordose segmental do nível operado, índice intraoperatório de lordose segmentar, mismatch pélvico (IP-LL), proporção de lordose distal, delta de lordose segmentar, PT > 20, inclinação sacral real e inclinação sacral ideal, e a correlação dessas variáveis com o ganho da lordose segmentar foi investigada. Posteriormente, foi realizada uma análise exploratória de cluster para identificar características comuns entre os pacientes e o ganho de lordose segmentar.
Resultados O presente estudo contou com 144 pacientes, dos quais 76% apresentaram ganho de lordose segmentar. Os parâmetros mais correlacionados com o ganho de lordose segmentar foram lordose segmentar pré-operatória (−0,50) e delta intraoperatório de lordose (0,51). Além disso, os pacientes dos grupos de incidência pélvica (IP) alto tiveram tendência de ganho de lordose segmental maior (p < 0,05) e redução do risco de perda de lordose segmental (chances 6.08).
Conclusão Pacientes com perfis de IP médios baixos apresentaram maiores chances de perda de lordose segmentar. No entanto, os parâmetros espinopélvicos pré-operatórios por si só não parecem desempenhar um papel significativo no destino do ganho da lordose segmentar.

Published: July 2022

Abstract
Introduction Free flaps have been the preferred method for reconstruction after resection of oral cavity cancer. However, pedicled flaps remain valuable alternatives in appropriate settings.
Objective The main objective of the present study was to compare surgical complications, hospital costs, and functional outcomes of oral cavity cancer patients who underwent soft tissue reconstruction with pedicled flaps or free flaps.
Methods A total of 171 patients were included in the study. Ninety-eight underwent reconstruction with a pectoralis major, submental, temporalis, or supraclavicular pedicled flap, and in 73 patients, a radial forearm or anterolateral thigh free flap had been used. The cases were retrospectively reviewed, and a comparative analysis was carried out between the two groups.
Results Recipient site and flap complications, speech, and swallowing functions did not differ between groups, but donor site complications, operative time, hospital stay, and costs were significantly reduced in the pedicled flap group compared with the free flap group. However, the pectoralis major flap reconstruction resulted in a more inferior swallowing function than the free flap reconstruction.
Conclusions With comparable complications and functional outcomes, while decreasing in costs, pedicled flaps are a useful alternative to free flaps in oral cavity cancer reconstruction. However, in an extensive defect (> 70 cm2), free flaps are the reconstruction of choice for the preservation of swallowing function.

Published: July 2022

Abstract
Background Synovial cysts (SCs) are the most frequent wrist tumors; the arthroscopic treatment presents good results when surgery is indicated for symptomatic or patients with cosmetic concerns. The tumoral lesion should be arthroscopically decompressed or drained toward the inside of the joint through pedicle opening and resection of a small portion of the capsule. Hence, the cyst pedicle must be found for the success of this technique.
Description of Technique Some tricks have already been described to facilitate SC location during arthroscopy. We describe an indirect technique that employs an 18-G needle to enhance SC pedicle location and drainage. The technique involves a puncture on the interval of the carpal extrinsic ligaments where the pedicle is suspected to be remain. When found, cyst is drained with a single-puncture motion of the need which promotes cyst content extravasation due to pressure toward the joint.
Patients and Methods This method has been employed in 16 patients, including 9 with dorsal cysts, and seven with volar cysts.
Results All patients presented complete recovery and symptom improvement in up to 30 days, with total disappearance of the cyst. There were no relapses or severe complications within the 12-month follow-up.
Conclusion This is a safe, useful technique that facilitates location of intra-articular cyst pedicle, thus avoiding unnecessary damage in healthy tissues with no increased costs.

Métodos Estudo retrospectivo, multicêntrico, de pacientes com instabilidade anterior do ombro submetidos à cirurgia de Latarjet modificada e no mínimo 1 ano de seguimento pós-operatório. Dois médicos radiologistas analisaram as imagens tomográficas pós-operatórias, adquiridas em um banco de dados, para avaliação do posicionamento dos parafusos e das complicações radiográficas.
Resultados Foram avaliados 34 pacientes, com idades entre 21 e 60 anos, sendo que um deles tinha acometimento bilateral dos ombros, totalizando 35 ombros avaliados. A avaliação tomográfica dos ângulos de inclinação dos parafusos não apresentou diferença entre os observadores. Houve concordância intra e interobservador para avaliação dos seguintes parâmetros cirúrgicos: posição do enxerto, presença ou não de complicações radiográficas.
Conclusão A técnica descrita para mensuração do paralelismo dos parafusos na cirurgia de Latarjet apresentou uma concordância intra e inter observador muito boa e excelente, respectivamente. O paralelismo do parafuso com a glenoide é recomendado; no entanto, não é condição obrigatória e única para se evitar as complicações radiográficas.
Herbal and Dietary Supplement Use among Adult Patients Undergoing Treatment at a Tertiary Hospital Cancer Center

Published: July 2022

AbstractThe use of herbal and dietary supplement in cancer patients has been increasing over the past years, while the risk of its adverse effects and undesirable reactions with conventional treatment has also been accumulating. Limited studies involving perception of herbal and dietary supplements (HDS) by cancer patients have been conducted in our setting. An initial survey was conducted among adult cancer patients undergoing treatment at the Zamboanga City Medical Center (ZCMC) Cancer Institute. HDS users were recruited for focus group discussion (FGD) via purposive sampling. A total of four groups were conducted. Clinical and demographic data were presented through descriptive statistics while data from the FGD were subjected to coding and thematic analysis. Among 22 respondents, more than half (65.4%) of the participants were noted to have used HDS and most (54.5%) were breast cancer patients with stage-II and -III disease. Treatment of cancer, coping with chemotherapy, and relief of symptoms were the major reasons for use. Majority (36.36%) were influenced by the media/internet and most (50%) did not disclose information to their physician. Eight respondents, whose income were below minimum wage, spent more than 25% of their income on HDS, with some having spent more than 50%. This may seriously limit funds and result in failure to adhere to treatment. Among cancer patients in ZCMC, HDS use is widely practiced and half of them do not disclose this information to their physicians. The expenditure on HDS consumes 25 to 50% of the population's meager monthly income. The secrecy surrounding its use and attendant cost may possibly limit adherence and adversely affect outcomes.

Abstract
Purpose The aim of this study was to compare the rates of recurrence and wound infection in patients with primary dorsal wrist ganglion treated with aspiration (with or without an injection of an additive), open excision, or arthroscopic resection.
Methods This systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines and registered on PROSPERO. Systematic electronic searches in PubMed (MEDLINE), EMBASE, Web of Science, and the Cochrane Library of Controlled Trials were performed on May 5, 2020, and June 1, 2021, respectively. All clinical studies written in English determining the recurrence and wound infection rates after treatment of primary dorsal wrist ganglion with aspiration, open excision, or arthroscopic resection in patients over the age of 16 years were eligible for inclusion. Quality assessment was guided by the Cochrane Collaboration's tool for randomized controlled trials (RCTs) and the methodological index for nonrandomized studies (MINORS) tool for observational studies.
Results The literature searches resulted in 1,691 studies. After screening, five RCTs, enrolling 233 patients, and six observational studies, enrolling 316 patients with primary dorsal wrist ganglions were included. Quality assessment of the included RCTs and observational studies determined the existing level of evidence pertaining to primary dorsal wrist ganglion treatment to be low. About 11 studies reported on recurrence rate, which ranged between 7 and 72% for patients initially treated with aspiration (with or without an injection of an additive). In comparison, the recurrence rate for the open excision and arthroscopic resection groups ranged between 6 to 41% and 0 to 16%, respectively. Four studies investigated wound-related complications, for which zero infections were reported, irrespective of treatment.
Conclusion The evidence summarized in this systematic review demonstrates a considerable variability in recurrence rate following aspiration and open or arthroscopic resection of a primary dorsal wrist ganglion. The greatest variability in recurrence was displayed among studies on aspiration. The overall infection rate after treatment of dorsal wrist ganglions seems to be low regardless of the treatment type. However, the divergent results of individual studies highlight a pressing need for prospective controlled trials assessing outcomes following dorsal wrist ganglion treatment.
Level of Evidence Systematic review on level 1 to 4 clinical therapeutic studies.
Development of a high dynamic range retarding potential analyzer for electric propulsion plume diagnosis
Authors: Maystrenko D. , Shagayda A. , Kravchenko D. , Lovtsov A. 
Published: July 2022

A new high dynamic range retarding potential analyzer design is proposed to measure the ion energy distribution in electric propulsion plasma plumes. The main difference between the proposed probe and previous designs is an ion-optical system with a high negative accelerating potential. Applying the principle of acceleration and focusing of the ion flow provides the correct operation of the probe in a dense plasma in which the Debye length can be ten times smaller than the diameter of the grid apertures. As a result, the new probe has high transparency with an extended operating range of measured plasma densities. Another advantage of the probe is its accurately known and time-stable transparency for ions, so the probe can measure the absolute values of the ion current density like the Faraday probe. The analyzer geometry, which provides measurement in the range of ion current densities up to 100 A/m2 at ion energies up to 2000 eV with an error of no more than 2%, was determined using numerical simulation. We present the measurement results of the plasma plume of a Hall effect thruster with a nominal discharge power of 2.3 kW.
Crucial role of S8-rings in structural, relaxation, vibrational, and electronic properties of liquid sulfur close to the λ transition
Authors: Flores-Ruiz H. , Micoulaut M. 
Published: July 2022

Liquid sulfur has been studied by density-functional based molecular dynamics simulations at different temperatures ranging from 400 up to 700 K across the well-documented λ transition. Structure models containing either a majority of Sn chains or S8 rings are considered and compared to experimental data from x-ray scattering. The comparison suggests a liquid structure of a majority of twofold sulfur at low temperature, dominated by S8 rings that open progressively upon temperature increase. Typical features associated with such rings are analyzed and indicate that they contribute to a specific third correlating distance in the pair correlation function and to a contribution at low wavevector k in the reciprocal space. The vibrational properties of liquid sulfur are also considered and indicate a contribution at 60 meV that is associated with both chains and rings, albeit the latter lead to a more intense peak at this wavenumber. The underlying network structure also impacts the dynamic properties of the melts which display enhanced dynamic heterogeneities when S8 rings are present. The analysis of the electronic Kohn–Sham energies shows insulating character with a gap of about ≃2.0 eV, albeit the presence of localized mid-gap states is acknowledged that can be associated, in part, with the presence of S6 rings.

The 300 kV DC high voltage photogun at Jefferson Lab was redesigned to deliver electron beams with a much higher bunch charge and improved beam properties. The original design provided only a modest longitudinal electric field (Ez) at the photocathode, which limited the achievable extracted bunch charge. To reach the bunch charge goal of approximately few nC with 75 ps full-width at half-maximum Gaussian laser pulse width, the existing DC high voltage photogun electrodes and anode–cathode gap were modified to increase Ez at the photocathode. In addition, the anode aperture was spatially shifted with respect to the beamline longitudinal axis to minimize the beam deflection introduced by the non-symmetric nature of the inverted insulator photogun design. We present the electrostatic design of the original photogun and the modified photogun and beam dynamics simulations that predict vastly improved performance. We also quantify the impact of the photocathode recess on beam quality, where recess describes the actual location of the photocathode inside the photogun cathode electrode relative to the intended location. A photocathode unintentionally recessed/misplaced by sub-millimeter distance can significantly impact the downstream beam size.

Published: July 2022

A detailed exploration of the potential energy surface of quinoline cation (C9H7N·+) is carried out to extend the present understanding of its fragmentation mechanisms. Density functional theory calculations have been performed to explore new fragmentation schemes, giving special attention to previously unexplored pathways, such as isomerization and elimination of HNC. The isomerization mechanisms producing five- to seven-membered ring intermediates are described and are found to be a dominant channel both energetically and kinetically. Energetically competing pathways are established for the astrochemically important HNC-loss channel, which has hitherto never been considered in the context of the loss of a 27 amu fragment from the parent ions. Elimination of acetylene was also studied in great detail. Overall, the computational results are found to complement the experimental observations from the concurrently conducted PEPICO investigation. These could potentially open the doors for rich and interesting vacuum ultraviolet radiation-driven chemistry on planetary atmospheres, meteorites, and comets.
Long-distance polarizing microscope system combined with solenoid-type magnet for microscopy and simultaneous measurement of physical parameters

Published: July 2022

We have developed a long-distance polarizing microscope system combined with a solenoid-type superconducting magnet. By inserting an infinity-corrected objective lens into the magnet, direct or polarizing microscope images are observed in magnetic fields of up to 12 T at various temperatures down to 2 K. Through magneto-optical measurements in the transmission geometry, the local magnetization process of a transparent magnet is evaluated in areas of 10 × 10 µm2. This system enables simultaneous measurements of other physical properties over a wide range of temperatures and magnetic fields. The basic principle of the proposed long-distance microscopy can be applied to imaging experiments in various research fields, particularly biology and chemistry.

Published: July 2022

Spin polarized scanning tunneling microscopy (SP-STM) and magnetic exchange force microscopy (MExFM) are powerful tools to characterize spin structure at the atomic scale. For low temperature measurements, liquid helium cooling is commonly used, which has the advantage of generating low noise but has the disadvantage of having difficulties in carrying out measurements with long durations at low temperatures and measurements with a wide temperature range. The situation is just reversed for cryogen-free STM, where the mechanical vibration of the refrigerator becomes a major challenge. In this work, we have successfully built a cryogen-free system with both SP-STM and MExFM capabilities, which can be operated under a 9 T magnetic field provided by a cryogen-free superconducting magnet and in a wide temperature range between 1.4 and 300 K. With the help of our specially designed vibration isolation system, the noise is reduced to an extremely low level of 0.7 pm. The Fe/Ir(111) magnetic skyrmion lattice is used to demonstrate the technical novelties of our cryogen-free system.
Strain effect on adsorption and reactions of AHx (A = C, N, O, x ≤ 3) on In2O3(110), TiO2(110), and ZrO2(101) surfaces
Authors: Lu Huili , Chen Zhao-Xu 
Published: July 2022

More and more attention has been paid to strain-based regulation of catalytic activity. To guide regulation of catalytic performance via strain engineering, adsorption and reactions of AHx (A = C, N, O, x ≤ 3) were investigated on uniformly strained In2O3 (110), rutile TiO2 (110), and tetragonal ZrO2 (101) from −2% to 4%. The results show that adsorption energies vary linearly with strain; expansive strain enhances the adsorption of most adsorbates. Unlike the adsorbate scaling relations that are central atom dependent, the adsorbate scaling relations on strained surfaces are central atom independent. C–H/O–H bonds are elongated/shortened with expansive strain, and adsorption energies of CHx generally change more than those of OHx and NHx, which can be rationalized with effective medium theory and pertinent bond energies. Thermodynamically, In2O3(110)/ZrO2(101) is the most active/inactive. The estimated variation of rate constants at 300 K from 0% to 2% strain based on the Brønsted–Evans–Polanyi relationship demonstrates great strain regulation potential of catalytic performance on these oxide surfaces. Finally, it is demonstrated that strain tends to facilitate the reactions whose sum of the stoichiometric number is positive, which can be used as a rule to guide strain engineering for heterogeneous catalysis.
