Published: May 2022

Background: Ultrasound guided peripheral nerve blocks have become increasingly popular in the lower limb orthopaedic and gaining more acceptances in total hip replacement surger­ies too. The main objective of this study was to compare peripheral nerve block and spinal anesthesia for total hip replacement surgeries.
Methods: In this retrospective study, total patients that underwent total hip replacement in our institution during specific time period were included for the study. They were divided into spinal and peripheral nerve block groups, and data were collected for the analysis. USG guided lumbar plexus, sacral plexus, superior gluteal nerve block was done and conventional landmark technique was done for spinal group. Mean arterial blood pressure, total fluid con­sumption, total fentanyl consumption, pain scores and incidence of nausea was compared.
Results: We included 43 patients for the study in which 23 patients were included in nerve block group, and 20 patients in the spinal group. In compared to spinal group, nerve block group had more stable mean arterial blood pressure (P <0.05), less total fluid consumption (P=.000), lower pain scores and fentanyl consumption (P <0.05), and less incidence of nausea (4% to 20%).
Conclusions: Peripheral nerve block can be good alternative to spinal anesthesia for total hip replacement surgeries, with more hemodynamic stability and better pain management along with less opioid and fluid consumption.

Background: Pulmonary Tuberculosis (PTB) is a major public health problem in Nepal. Diag­nosis of pulmonary tuberculosis is done by bacteriological confirmation of respiratory speci­men however Negative smear needs clinical and radiological evaluation for the diagnosis in suspected patient. This study focuses on radiological findings in both Pulmonary bacterio­logically confirmed (PBC) and pulmonary clinically diagnosed (PCD) Tuberculosis.
Methods: This observational study was conducted at Chitwan Medical College between Feb 2019 to July 2019. 45 Patient diagnosed with PTB were enrolled. Chest X-ray (CXR) and High Resolution Computed Tomography (HRCT) chest reports were analysed for the presence of findings that suggest active infection like cavity, consolidation, tree in bud, etc in PBC and PCD.
Results: A total of 45 PTB patients with mean age: 54.60 ± 19 years were included. 53.3 % were PBC and 46.7 % were PCD tuberculosis, CXR findings in PBC and PCD tuberculosis was nodular infiltrate 45.8% versus 2.4%, consolidation 45% versus 42.9%, cavity 8.3% versus 14.3% respectively however 12.5% PBC tuberculosis patient had a normal chest x-ray. HRCT chest in PBC and PCD showed cavity in 45.8% versus 23%, tree in bud 25% versus 52.4%, con­solidation 62.5 versus 57.1%, ground glass opacity 29.2% versus 23.8% respectively and none of the HRCT chest was normal. In comparison to the CXR, HRCT chest shows more cavitary lesions in PBC and tree in bud was more common in PCD.
Conclusions: This study has found that radiological findings suggestive of active PTB was more obvious in HRCT than CXR. Presence of cavity, lobar consolidation and tree in bud lesion in HRCT chest were more frequently observed in both PBC and PCD Tuberculosis.

Based on existing data, comorbid hypertension and diabetes mellitus, male gender, and active smoking are risk factors for SARS-CoV-2 infection. Diabetes mellitus (DM) is a metabolic disorder that affects insulin action in glucose absorption. A study conducted by Parveen et al showed that diabetes made the general health condition of COVID-19 patients worse. COVID-19 patients require hospitalization because COVID-19 is a highly contagious respiratory infectious disease, which can cause respiratory, physical, and psychological dysfunction of the patient, also resulting in various dysfunctions, which in turn can reduce the patient's functional capacity. This study aims to determine the difference in length of stay for COVID-19 patients with comorbid diabetes mellitus based on gender at Natar Medika Hospital, South Lampung in 2021. This type of research uses a comparative descriptive research method. The research design used in this study was cross sectional. Samples that met the inclusion and exclusion criteria were 40 patients' medical records. Gender characteristics were dominated by 24 women (60%) and 16 men (40%). A total of 14 female patients (58.3%) and 12 male patients (75%) recovered quickly. While 4 male patients (25%) and 10 female patients (41.7%) recovered for a long time. It is known that there is no significant comparison of length of stay for COVID-19 patients with comorbid diabetes mellitus based on gender where the Mann-Whitney test obtained a significance level (ρ value) of 0,466.

Computational Study on Optoelectronic Properties of Donor-Acceptor Type Small π-Conjugated Molecules for Organic Light-Emitting Diodes (OLEDs) and Nonlinear Optical (NLO) Applications
Authors: Zaier Rania , Ayachi Sahbi 
Published: May 2022

Recently, donor-acceptor type molecule that contains electron-rich (D) and electron-deficient (A) moiety has emerged as an interesting approach of molecular design strategy to develop organic light-emitting diodes (OLEDs) and non-linear optical (NLO) devices. In this work, we report a theoretical investigation based on two donor-acceptor (D-A) type small π-conjugated molecules based on dithieno [3,2-b: 2′,3′-d] pyrrole (DTP) and anthracene derivatives. All of the theoretical calculations were performed by Density Functional Theory (DFT) approach at B3LYP/6-31 g(d) level of theory. The structural, electronic, optical and charge transfer properties were investigated. The effect of acceptor blocks (DPA and DTA) on the molecular characteristics was elucidated. The obtained results clearly show that the studied compounds exhibit non-coplanar structures with low electronic band gap values. These relevant structures exhibited important optical absorption and intense emission in the green-yellow region. NLO investigation based on static polarizability (α0), first-order hyperpolarizability (β0) and second-order hyperpolazabilty (ɣ0) demonstrated that the studied materials exhibit excellent NLO properties. Thus, the designed materials showed promising capabilities to be utilized in OLED and NLO applications.

AbstractOpportunities to improve thermal management in electronic devices are currently hindered by processing constraints that limit thermal conductivity in polymer‐matrix composites. Active patterning of filler particles is a promising route to improve conductivity while retaining processability by improving particle contact density and directing heat along optimized pathways. This study employs acoustic patterning to align and compact filler particles into stripes during stereolithographic 3D printing. This approach produces polymer‐based composite materials with highly efficient embedded heat transport pathways which reach 95 vol% particle utilization (relative to the parallel conduction upper limit). These composites exhibit anisotropic thermal conductivity up to 300% higher than unpatterned composites, with in‐plane anisotropy ratios of up to 350%. Combining this high conductivity with 3D printing enables materials with engineered heat networks that optimize transport from hot spots to heatsinks while maintaining low viscosity for fast particle patterning and for infiltration around electronic components. Finally, numerical simulations of acoustic assembly of particles with varied geometry, when compared to experimentally characterized particle packing, illuminate pathways for further improving conductivity by optimizing particle geometry for alignment and stacking of particles with maximum contact surface area.

Published: May 2022

AbstractNanostructured scaffolds that optimize self‐responsive ability, visible light harvesting, redox center distribution, and species shuttling porosity have been mimicked much less often, especially using organic crystalline substances. Inspired by a natural photosynthetic thylakoid membrane, a synthetic strategy with general applicability to construct a hollow organic crystalline nanosphere by orderly hybridizing imine‐linked covalent organic frameworks (COFs) with polymeric hollow g‐C3N4 nanosphere is proposed. As a proof‐of‐concept application, in a homemade microreaction cell, these hollow organic nanospheres are shown to function as robust scaffolds, heterojunction shells, and light‐harvesting antennas, enabling excellent visible‐light‐driven photocatalysis for the almost complete degradation of tetracycline, a gravely residual antibiotic worldwide. Significantly, a new electrochemiluminescence (ECL) technology derived from biomimetic self‐responsiveness is developed for in situ evaluation of the photodegradation process, accessing kinetics and other relevant parameters at an extremely low‐abundance target, which remains challenging to date, albeit highly desirable. This work provides a general synthetic strategy for obtaining COFs‐derived hollow crystalline organic nanospheres for promising photocatalysis applications and offers a new perspective on the development of ECL technology for simultaneous analysis and treatment of actual sewage.

AbstractTi3C2Tx MXene film is promising for electrochemical actuators due to its high electrical conductivity and volumetric capacitance. However, its actuation performance is limited by the slow ion diffusion through the film and poor mechanical property in aqueous electrolytes. Here, molecular‐level methylcellulose (MC)/MXene hybrid films are assembled with obviously enlarged layer distance, improved wet strength, and ambient stability. The hybrid films show significantly higher in‐plane actuation strain in a liquid electrolyte. Based on direct strain measurements, in situ X‐ray diffraction (XRD) and ex situ X‐ray photoelectron spectroscopy (XPS) analyses, the actuation enhancement can be ascribed to the enlarged layer distance allowing more water and ions to be intercalated/de‐intercalated and MC‐induced sliding of MXene sheets. The assembled soft actuator has a high Young's modulus of 1.93 GPa and can be operated in air, generating a peak‐to‐peak strain difference up to 0.541% under a triangular wave voltage of ±1 V and a blocking force of 4.7 times its own weight.

AbstractGlobally, liver cancer, which is one of the major cancers worldwide, has attracted the growing attention of technological researchers for its high mortality and limited treatment options. Hydrogels are soft 3D network materials containing a large number of hydrophilic monomers. By adding moieties such as nitrobenzyl groups to the network structure of a cross‐linked nanocomposite hydrogel, the click reaction improves drug‐release efficiency in vivo, which improves the survival rate and prolongs the survival time of liver cancer patients. The application of a nanocomposite hydrogel drug delivery system can not only enrich the drug concentration at the tumor site for a long time but also effectively prevents the distant metastasis of residual tumor cells. At present, a large number of researches have been working toward the construction of responsive nanocomposite hydrogel drug delivery systems, but there are few comprehensive articles to systematically summarize these discoveries. Here, this systematic review summarizes the synthesis methods and related applications of nanocomposite responsive hydrogels with actions to external or internal physiological stimuli. With different physical or chemical stimuli, the structural unit rearrangement and the controlled release of drugs can be used for responsive drug delivery in different states.

AbstractElectrode architectures significantly influence the electrochemical performance, flexibility, and applications of lithium‐ion batteries (LiBs). However, the conventional bar coating for fabricating electrodes limits the addition of customized architecture or patterns. In this study, as a novel approach, patterns are integrated into electrodes through large‐scale roll‐to‐roll (R2R) flexographic printing. Additionally, flexible, recyclable, and biodegradable paper are innovatively used as a printing substrate during printing LiBs manufacturing, which exhibited superior printability. Moreover, the paper is modified with a thin‐layer Al2O3 to function as the separator in the printed LiB. The Al2O3‐coated paper enables an admirable wettability for printing, excellent mechanical properties for high‐speed R2R manufacturing, and outstanding thermal stability for the safe and stable operation of LiBs. The assembled paper cells exhibit nearly 100% discharge capacity retention after 1000 cycles at 3 C and outstanding rate performance. This work inspires future large‐scale microbatteries manufacturing integrated with high‐resolution architecture designs.

Published: May 2022

AbstractMedical electrophysiological sensors that can study the body and diagnose diseases depend on consistently low impedance electrode–skin interfaces. Clinical‐standard wet electrodes use hydrogels and skin abrasion to improve the interface and thus the recorded signal quality. These electrodes are challenging to self‐administer and impede in‐home care. Wearable dry electrodes are more practical; however, they show higher impedances than wet electrodes and are costly to customize. This work presents a fabrication method for rapidly producing low impedance, anatomically fit dry electrodes that do not require hydrogels. By using electroless copper and gold plating with 3D printing, biocompatible electrodes can be optimized for individuals at a fraction of the cost of existing vacuum deposition‐based techniques. Example 3D dry electrodes made with this process are evaluated alongside clinical‐standard devices in typical scenarios to compare electrical performance and comfort. The resulting dry electrodes exhibit an average electrode‐skin impedance of 66.7 kΩ at 50 Hz and DC offset of −20 mV without any hydrogel, which, when area normalized, is within the range achieved by wet electrodes without skin abrasion.
