RESUMO
PURPOSE: We developed model eyes using six polymer materials to determine which materials were most appropriate in simulating real human sclera and extraocular muscle (EOM). METHODS: Five three-dimensional (3-D) printed polymers (FlexFill, PolyFlex, PCTPE, Soft PLA, and NinjaFlex) and one silicone material were systematically tested by board-certified ophthalmologists and senior ophthalmology residents. Material testing included scleral passes with 6-0 Vicryl sutures through each eye model. Participants completed a survey designed to collect demographic data, subjective assessment of each material's accuracy in simulating real human sclera and EOM, and a ranking for each polymer material to identify which would be most suitable for an ophthalmic surgery training tool. The Wilcoxon signed-rank test was conducted to determine if there was a statistically significant difference in the distribution of ranks between the polymer materials. RESULTS: The distribution of ranks for silicone material's "sclera" and "EOM" components were statistically significantly higher than that of all other polymer materials (all p < 0.05). Silicone material received the highest rank for both "sclera" and "EOM" components. Survey results indicated that the silicone material effectively simulated real human tissue. CONCLUSION: Silicone model eyes performed better than 3-D printed polymers as an educational tool for incorporation into a microsurgical training curriculum. Silicone models provide a low-cost teaching tool that allows for independent practice of microsurgical techniques without requiring a wet-laboratory facility.

We demonstrate the development of a new atmospheric pressure-atomic layer deposition(AP-ALD) system to coat the inner walls of capillary columns for gas chromatography (GC). Unlike traditional ALD, this reactor operates at near-atmospheric pressure and addresses the challenges of depositing thin films inside capillaries, which include long pump down times, deposition in high-aspect-ratio materials, and temperature control. We show ALD of alumina in 5 and 12 m capillaries (0.53 mm ID) via sequential half reactions of trimethylaluminum and water. Our system yields pinhole-free, uniform thin films. It includes small witness chambers for witness silicon shards before and after the capillary. An engineering flow/transport analysis of the device is provided. Our ALD alumina thin films are characterized by spectroscopic ellipsometry (SE), X-ray photoelectron spectroscopy, transmission electron microscopy (TEM), and energy-dispersive X-ray spectroscopy. Alumina film growth achieved is 1.4-1.5 Å/cycle, which is consistent with previously reported results. Film thickness measurements by SE on witness shards of silicon and by TEM at both ends of the capillary are in good agreement. A capillary column coated with alumina is used to separate different gases by GC, although the retention times of gases are essentially the same as with an untreated fused silica capillary. This successful deposition of ALD alumina in long capillaries opens the door for other possible ALD coatings, including hybrid organic-inorganic coatings, using the 450+ ALD precursors available today.
RESUMO
Colorectal hypersensitivity and sensitization of both mechanosensitive and mechanically insensitive afferents develop after intracolonic instillation of 2,4,6-trinitrobenzenesulfonic acid (TNBS) in the mouse, a model of postinfectious irritable bowel syndrome. In mice in which â¼80% of extrinsic colorectal afferents were labeled genetically using the promotor for vesicular glutamate transporter type 2 (VGLUT2), we systematically quantified the morphology of VGLUT2-positive axons in mouse colorectum 7-28 days following intracolonic TNBS treatment. After removal, the colorectum was distended (20 mmHg), fixed with paraformaldehyde, and optically cleared to image VGLUT2-positive axons throughout the colorectal wall thickness. We conducted vector path tracing of individual axons to allow systematic quantification of nerve fiber density and shape. Abundant VGLUT2-positive nerve fibers were present in most layers of the colorectum, except the serosal and longitudinal muscular layers. A small percentage of VGLUT2-positive myenteric plexus neurons was also detected. Intracolonic TNBS treatment significantly reduced the number of VGLUT2-positive nerve fibers in submucosal, myenteric plexus, and mucosal layers at day 7 post-TNBS, which mostly recovered by day 28. We also found that almost all fibers in the submucosa were meandering and curvy, with â¼10% showing pronounced curviness (quantified by the linearity index). TNBS treatment resulted in a significant reduction of the proportions of pronounced curvy fibers in the rectal region at 28 days post-TNBS. Altogether, the present morphological study reveals profound changes in the distribution of VGLUT2-positive fibers in mouse colorectum undergoing TNBS-induced colitis and draws attention to curvy fibers in the submucosa with potential roles in visceral nociception.NEW & NOTEWORTHY We conducted genetic labeling and optical clearing to visualize extrinsic sensory nerve fibers in whole-mount colorectum, which revealed widespread presence of axons in the submucosal layer. Remarkably, axons in the submucosa were meandering and curvy, in contrast to axons in other layers generally aligned with the basal tissues. Intracolonic TNBS treatment led to pronounced changes of nerve fiber density and curviness, suggesting nerve fiber morphologies as potentially contributing factors to sensory sensitization.

Endothelial cell (EC) sensing of fluid shear stress direction is a critical determinant of vascular health and disease. Unidirectional flow induces EC alignment and vascular homeostasis, whereas bidirectional flow has pathophysiological effects. ECs express several mechanoreceptors that respond to flow, but the mechanism for sensing shear stress direction is poorly understood. We determined, by using in vitro flow systems and magnetic tweezers, that ß1 integrin is a key sensor of force direction because it is activated by unidirectional, but not bidirectional, shearing forces. ß1 integrin activation by unidirectional force was amplified in ECs that were pre-sheared in the same direction, indicating that alignment and ß1 integrin activity has a feedforward interaction, which is a hallmark of system stability. En face staining and EC-specific genetic deletion studies in the murine aorta revealed that ß1 integrin is activated and is essential for EC alignment at sites of unidirectional flow but is not activated at sites of bidirectional flow. In summary, ß1 integrin sensing of unidirectional force is a key mechanism for decoding blood flow mechanics to promote vascular homeostasis.This article has an associated First Person interview with the first author of the paper.

We report the fabrication of 6-phenylhexylsilane derivatized, sputtered silicon, solid phase microextraction fibers that show parts per trillion detection limits for polyaromatic hydrocarbons, and negligible carry over and phase bleed. Their fabrication involves sputtering silicon on silica fibers under various conditions. Six different fibers were evaluated by generating three different thicknesses of sputtered silicon at two different throw distances, which altered the morphologies of the silicon surfaces. All of the fibers were coated with similar thicknesses of 6-phenylhexylsilane (ca. 2 nm). These fibers were characterized with multiple analytical techniques. The optimum fiber configuration was then used to analyze polyaromatic hydrocarbons via direct immersion, gas chromatography mass spectrometry. Our best fiber for the extraction of low molecular weight polyaromatic hydrocarbons in water had similar performance to that of a commercial fiber. However, our fiber demonstrated ca. 3 times the extraction efficiency for higher molecular weight polyaromatic hydrocarbons. In addition, it outperformed the commercial fiber by showing better linearity, repeatability, and detection limits. A method for analyzing polyaromatic hydrocarbons in baby formula was developed, which showed very good linearity (0.5-125 ppb), repeatability (2-26%), detection limits (0.12-0.81 ppb), and recoveries (103-135%). In addition, our fiber showed much less (negligible) carry over and phase bleed than the commercially available fibers.

Paraquat (1,1'-dimethyl-4, 4'-dipyridylium) is a broad-spectrum liquid herbicide associated with both accidental and intentional ingestion leading to severe and often fatal toxicity.1 Paraquat is actively taken up against a concentration gradient into lung tissue leading to pneumonitis and lung fibrosis. Paraquat also causes renal and liver injury.2 There are few case publications of paraquat poisoning and only few of them have reported that renal failure has ensued before acute respiratory distress syndrome (ARDS). Our patient presented with above lethal dose intake of paraquat containing substance and we did gastric lavage followed by charcoal hemoperfusion and hemodialysis but patient could not be saved despite optimum efforts suggesting the high fatality of this kind of poisoning. HOW TO CITE THIS ARTICLE: Sharma DS, Prajapati AM, Shah DM. Review of a Case of Paraquat Poisoning in a Tertiary Care Rural-based ICU. Indian J Crit Care Med 2019;23(6):284-286. KEY MESSAGES: Acute renal injury with hypoperfusion state due to toxicity at cellular level, redox cycling and intracellular reactive oxidative stress generation may also cause death in early stages in paraquat poisoning despite optimal management.
RESUMO
Isonitriles are delicately poised chemical entities capable of being coaxed to react as nucleophiles or electrophiles. Directing this tunable reactivity with metal and non-metal catalysts provides rapid access to a large array of complex nitrogenous structures ideally functionalized for medicinal applications. Isonitrile insertion into transition metal complexes has featured in numerous synthetic and mechanistic studies, leading to rapid deployment of isonitriles in numerous catalytic processes, including multicomponent reactions (MCR). Covering the literature from 1990-2014, the present review collates reaction types to highlight reactivity trends and allow catalyst comparison.
RESUMO
This case report presents a comprehensive analysis of a 48-year-old woman diagnosed with pituitary macroadenoma, detailing the clinical presentation, surgical intervention, and postoperative management. The patient exhibited a complex array of symptoms, including persistent headaches, insomnia, and anemia, with a history of trauma and blood transfusion. Magnetic Resonance Imaging (MRI) confirmed the presence of a large, lobulated pituitary macroadenoma, prompting a trans-nasal trans-sphenoidal endoscopic excision. The surgical procedure was successful, but postoperative complications, revealed by a CT scan, included hyperdense lesions and mixed-density collections. Incorporating antibiotics, analgesics, antacids, and anti-emetics, vigilant postoperative care addressed these complications. This case underscores the challenges and successes in managing pituitary macroadenomas, highlighting the importance of individualized care, multidisciplinary collaboration, and ongoing research for optimizing patient outcomes. The insights gained from this case contribute to the evolving understanding and refinement of strategies for addressing these complex tumors.
RESUMO
Nalbuphine, a semi-synthetic opioid, has gained attention for its analgesic properties, but its specific impact on hemodynamics in ear, nose, and throat (ENT) surgeries remains a subject of exploration. This comprehensive review aims to systematically analyze existing literature to understand the nuanced hemodynamic effects of nalbuphine during ENT procedures. Nalbuphine demonstrates promise as an analgesic agent in ENT surgeries with generally stable hemodynamic profiles. However, the variability in study designs and outcomes necessitates a cautious interpretation. The review underscores the need for standardized protocols and further research to elucidate patient-specific considerations, ensuring optimal utilization of nalbuphine in enhancing overall perioperative care for ENT patients.
RESUMO
Introduction: Hip dislocations are mainly high-energy injuries which generally occur posteriorly. The anterior dislocations of the hip are rare and this dislocation coupled with a neck of femur fracture is very less likely. Case Report: This article presents a rare and challenging case of a 43-year-old chronic alcoholic man with an anterior hip dislocation and ipsilateral neck of femur fracture. The patient's history revealed a seemingly trivial domestic fall, but on examination, he exhibited severe pain, limb shortening, and external rotation in the left hip joint. Radiographic assessments initially suggested a posterior femoral head dislocation, but a subsequent computed tomography scan revealed an unusual scenario - the fractured femoral head had displaced anteriorly, traversing over the iliac wing, and settling in the pelvic cavity. Discussion of this unique case explores the infrequent association of anterior traumatic hip dislocations with femoral neck fractures. Prognosis in such cases is generally poor, with considerations for factors such as time to surgery, surgical findings, and patient age playing a crucial role in determining the optimal treatment strategy. The article delves into the challenges posed by the presented case, emphasizing the importance of appropriate diagnosis and surgical planning in managing these complex injuries. Conclusion: The rarity of the presented injury, coupled with the unexpected clinical course following surgery, underscores the importance of maintaining a high index of suspicion for unusual presentations, even in seemingly minor traumas. This article contributes valuable insights into the diagnosis, surgical management, and challenges associated with the rare combination of anterior hip dislocation and ipsilateral neck of femur fracture.
RESUMO
Introduction: Cysticercosis leads to a cyst formation known to occur due to the Taenia solium parasite. Patients normally present with seeding and formation of the cysts in the central nervous system (CNS) as neurocysticercosis (NCC). Intramuscular cysts are rare presentations and are mostly incidental findings in NCC patients. We present a rare case of a rapidly progressing isolated cysticercosis of the flexor digitorum profundus (FDP) muscle leading to a pseudotumor and presenting with pseudo-Volkmanns contracture and a positive Volkmanns sign. Case Report: A 26-year-old right-hand dominant vegetarian female presented with a 3-month-old progressive swelling on her right forearm with no antecedent trauma history. A positive Volkmann's sign was present. Radiographs were normal, and ultrasonography showed a cysticercus cyst in the FDP muscle belly with a multiseptated abscess around the tendons of the middle, ring, and little fingers at the musculotendinous junction. Bones and nerves were spared. After ruling out CNS involvement and providing oral antiparasitic cover, she underwent a successful surgical exploration with cyst excision, debridement, and freeing of the involved tendons. Immediately post-operatively, she was able to completely extend the three involved fingers without flexion at the wrist joint (resolving Volkmann's sign). She reported significant improvements in the functions of daily life. She was protected with a splint for 2 weeks. There was no recurrence, and the swelling subsided. Histo-pathology reports depicted cysts with visible scolices. Conclusion: It is important to consider the possibility of 'Myoparasitism' in atraumatic cases showing contractures. Clinching the right diagnosis is essential and best done with a multidisciplinary approach with ultrasonography, magnetic resonance imaging, electromyography, and nerve conduction velocity studies. It is essential to rule out life-threatening NCC beforehand and offer prophylaxis. Surgical exploration is generally indicated to regain normal function and free the involved structures.
RESUMO
Backgroundobjectives: To compare the structural anatomy of the anterior segment in pediatric Trisomy 21 (T21) subjects with and without cataracts to age-matched controls. Design: Prospective case-control study. Participants: 40 subjects (57 eyes) age 0-25 years old (9.1 ± 10.6 years). Methods: This prospective case-control study evaluated anterior segment measurements from ultrasound biomicroscopy (UBM) imaging on 342 images. Results: Among persons with T21 cataract, the iris was significantly thinner than T21 individuals without cataract (0.28 vs 0.32 mm, p = 0.0181). T21/cataract subjects also had significantly thinner lenses than subjects without cataract, regardless of whether they have T21 or are controls (3.1 mm vs 3.5 mm, p = 0.0074).Thinner lens (<3.5 mm) was insignificantly associated with increased odds of cataract (OR = 9.5 [0.872,104], p = 0.065). Thinner iris (<0.32 mm) was associated with increased odds of cataract (OR = 8.4 [1.188, 59.273], p = 0.033). Conclusions: These findings support the hypothesis that subtle quantitative anatomic variants are present in the anterior eye of individuals with T21. Specific anatomic variants are unique to the presence of cataract among subjects with T21.

RESUMO
INTRODUCTION: People living with HIV (PLWH) receiving statin therapy have shown improved lipid profiles. However, they are not free from side effects, thereby requiring strict monitoring of the therapy. The meta-analysis aims to analyze the effect of statins in PLWH and critically appraise the effectiveness of statin therapy in PLWH. METHODS: PubMed, Scopus, and Web of Science servers were used to conduct a systematic search in compliance with the PRISMA guidelines. The meta-analysis of pooled effect estimates is produced using Revman software. RESULTS: A total of 12 RCTs with 8716 participants were included in the analysis. Analysis of the overall effect estimates found that statins resulted in a mean reduction of 41.15 mg/dl (MD = -41.15; 95% CI: -44.19, -38.11; p < 0.00001), 34.99 mg/dl (MD = -34.99; 95% CI: -34.99; 95% CI: -41.16, -28.82; p < 0.00001), and 7.36 mg/dl (MD = -7.36; 95% CI = -48.35, -33.62; p < 0.00001) in total cholesterol, low-density lipoprotein, and triglyceride levels, respectively. It is revealed that statins are associated with a significant increase in the discontinuation rate of treatment compared to placebo treatment (RR: 1.90; 95% CI: 1.36-2.65; p = 0.0002). CONCLUSION: When considered collectively, statin therapy's advantages appear to exceed its occasional predictable side effects like liver or muscle toxicity.

Objective. Commonly recommended drugs for adults and children include proton pump inhibitors (PPIs), proven effective for treating peptic diseases like stomach ulcers, GERD, and Helicobacter pylori infections in children over 1-year-old. Yet, prolonged PPI use carries higher risks of adverse reactions, prompting this study's analysis. Methods. We have performed a systematic review of 30 articles, which include a total of 762 505 pediatric patients. Results. Adverse effects were encountered in 6.98% of the population. The 5 most common adverse effects were respiratory tract complications, gastrointestinal complications, urinary tract infections, asthma, and ENT infections. Conclusion. Hence, PPIs should be prescribed only when necessary, and physicians should prioritize patient education when considering their use.
RESUMO
Navigation is one of the most heavily studied problems in robotics and is conventionally approached as a geometric mapping and planning problem. However, real-world navigation presents a complex set of physical challenges that defies simple geometric abstractions. Machine learning offers a promising way to go beyond geometry and conventional planning, allowing for navigational systems that make decisions based on actual prior experience. Such systems can reason about traversability in ways that go beyond geometry, accounting for the physical outcomes of their actions and exploiting patterns in real-world environments. They can also improve as more data is collected, potentially providing a powerful network effect. In this article, we present a general toolkit for experiential learning of robotic navigation skills that unifies several recent approaches, describe the underlying design principles, summarize experimental results from several of our recent papers, and discuss open problems and directions for future work. This article is part of the theme issue 'New approaches to 3D vision'.

Background: Optimal component placement,â¯equalizationâ¯of leg lengths, and recreation of offset are important surgical objectives during total hip arthroplasty (THA). Historically, many surgeons have aimed for the Lewinnek's "â¯safe zone," which is defined as 30°-50° of abduction and 5°-25° ofâ¯anteversion. Methods forâ¯optimizingâ¯cup position include anatomic landmarks, room landmarks, acetabular cup coverage, and ischial or pubis palpation. Malpositionâ¯of the acetabular component after total hip arthroplasty (THA) is related to dislocation of the prosthetic femoral head, increased polyethylene liner wear, and limited range of motion. The orientation of the acetabular component comprises inclination and anteversion. Although the inclination of the acetabular component can be easily measured on plain radiographs, the calculation of the anteversion is difficult. This study evaluates the effect of intra-operative fluoroscopy on component position, mainly anteversion and inclination of the acetabular cup, during a total hip arthroplasty. Methods: 106 hips undergoing total hip arthroplasty were assessed, and the decision to use fluoroscopy assistance was randomized based on a simple randomization technique. A total of 48 patients were operated on with fluoroscopy assistance and 58 patients without fluoroscopy assistance. All patients were evaluated postoperatively for version of component on anteroposterior radiographs of the hip using the method of Liaw et al. and for inclination of component on anteroposterior radiographs using the method of Woo and Morrey. Results: The mean version for the non-fluoroscopy (NF) group was 15.62° and the mean inclination was 44.22°, with 15.5% (9 out of 58) of the patients who did not fit into Lewinnek's safe zone for version and 25.9% (15 out of 58) of the patients who were outliers for inclination of the acetabular cup position. The mean version for the fluoroscopy group (F) was 11.80° and the mean inclination was 47.05°, with 0% (0 out of 48) of the patients who did not fit into Lewinnek's safe zone for version and 12.5% (6 out of 48) of the patients who were outliers for inclination of the acetabular cup position. Conclusion: While the mean version and inclination of the acetabular component were comparable for both groups, outliers for version and inclination were far more common in the group of patients who underwent surgery without intra-operative fluoroscopic assistance. Therefore, intra-operative fluoroscopy imaging confirms appropriate inclination (abduction) and version of acetabular cup position according to Lewinnek's safe zone and prevents undesirable component position during a total hip arthroplasty while adding a maximum of 5 min to the operative time.
RESUMO
Background: The chest radiograph (CXR) is the most frequently performed radiological examination worldwide. The increasing volume of CXRs performed in hospitals causes reporting backlogs and increased waiting times for patients, potentially compromising timely clinical intervention and patient safety. Implementing computer-aided detection (CAD) artificial intelligence (AI) algorithms capable of accurate and rapid CXR reporting could help address such limitations. A novel use for AI reporting is the classification of CXRs as 'abnormal' or 'normal'. This classification could help optimize resource allocation and aid radiologists in managing their time efficiently. Methods: qXR is a CE-marked computer-aided detection (CAD) software trained on over 4.4 million CXRs. In this retrospective cross-sectional pre-deployment study, we evaluated the performance of qXR in stratifying normal and abnormal CXRs. We analyzed 1040 CXRs from various referral sources, including general practices (GP), Accident and Emergency (A&E) departments, and inpatient (IP) and outpatient (OP) settings at East Kent Hospitals University NHS Foundation Trust. The ground truth for the CXRs was established by assessing the agreement between two senior radiologists. Results: The CAD software had a sensitivity of 99.7% and a specificity of 67.4%. The sub-group analysis showed no statistically significant difference in performance across healthcare settings, age, gender, and X-ray manufacturer. Conclusions: The study showed that qXR can accurately stratify CXRs as normal versus abnormal, potentially reducing reporting backlogs and resulting in early patient intervention, which may result in better patient outcomes.
RESUMO
Background and Aims: Marburg virus (MARV) has regularly affected people since 1967 causing multiple outbreaks. There are presently no authorized therapies for the fatal Marburg virus disease (MVD), which poses an imminent risk to global public health. The MVD has so far claimed the lives of numerous people, with an increased number of cases being seen throughout the African continent. Hence, a review was carried out to analyze the geographical distribution of MVD, mortality, routes of transmission, and diagnostic and treatment modalities. Methods: PubMed, Scopus, Web of Science, Google Scholar, and ProMED servers were used to conduct a systematic search in compliance with the PRISMA guidelines. The results were tabulated and analyzed. Results: A total of 11 studies (7 case reports and 4 case series) were included in the final analysis, and 21 cases of MVD were analyzed. The most frequent symptoms were fever (66.67%), vomiting (57.14%), headache (52.38%), diarrhea (52.38%), and pain (47.62%). The most commonly used diagnostic test was RT-PCR (42.11%). Contact transmission (50%) and zoonotic transmission (37.5%) were the most prevalent routes of transmission. Antibiotics (61.5%) were the first line of treatment. The most common complications were hemorrhage (60%) and coagulopathies (33.3%). The mortality rate was 57.1%. Conclusion: To avoid disastrous consequences, it is essential to reiterate the necessity of early diagnosis and treatment of MVD.
RESUMO
In this paper, we analyze the impact of COVID-19 in India and the nation's shortcomings in responding appropriately to the pandemic. We discuss how international vaccine inequities, rooted in neocolonialism, and the WHO's broad recommendation of Global North pandemic responses (i.e., lockdowns, nonspecific social distancing) blunted the effectiveness of India's COVID-19 response and instead heightened classism, economic turmoil, and unnecessary infection and death from the virus.
