RESUMEN
Scientific knowledge is produced in multiple languages but is predominantly published in English. This practice creates a language barrier to generate and transfer scientific knowledge between communities with diverse linguistic backgrounds, hindering the ability of scholars and communities to address global challenges and achieve diversity and equity in science, technology, engineering and mathematics (STEM). To overcome those barriers, publishers and journals should provide a fair system that supports non-native English speakers and disseminates knowledge across the globe. We surveyed policies of 736 journals in biological sciences to assess their linguistic inclusivity, identify predictors of inclusivity, and propose actions to overcome language barriers in academic publishing. Our assessment revealed a grim landscape where most journals were making minimal efforts to overcome language barriers. The impact factor of journals was negatively associated with adopting a number of inclusive policies whereas ownership by a scientific society tended to have a positive association. Contrary to our expectations, the proportion of both open access articles and editors based in non-English speaking countries did not have a major positive association with the adoption of linguistically inclusive policies. We proposed a set of actions to overcome language barriers in academic publishing, including the renegotiation of power dynamics between publishers and editorial boards.

PURPOSE: Beta-lactam allergy (BLA) is associated with increased broad-spectrum antibiotic (Br-ABX) use and worse clinical outcomes. We evaluated our hospital-wide BLA protocol (BLA-P) that used following categories: intolerance, low-risk, and high-risk. METHODS: Hospitalized adult patients with listed BLA during 10/2021-12/2022 were eligible. Exclusions were critically ill, surgical, hospice or comfort care, or non-verbal patients. Assessment was counted each time a pharmacist evaluated BLA. Interventions were no further action (high-risk allergy, patient refusal, unstable clinical status), updated allergy label, or delabeled. Delabeling was done either based on antibiotic history (direct-delabeling), or via test-dose challenge for low-risk patients. Br-ABX usage was compared in the unique delabeled patients: the empiric antibiotic use 90 days post-delabeling versus pre-delabeling using McNemar test (SPSS). RESULTS: A total of 700 assessments in 631 patients were identified. 441 assessments in 377 patients (median 63 years-old, 41% male, 50% hematological cancer) met inclusion criteria. The assessments revealed 9% intolerance, 55% low-risk, 23% high-risk and 13% unknown reaction. Interventions resulted in no further action 7%, updated label 72%, and delabeling 21%. 65% of the delabeling was via direct-delabeling and 35% test-dose challenge. Among patients who received a test-dose challenge, 36/36(97%) had no documented allergic reactions, and 1/26(3%) developed a mild rash. The use of aztreonam (pre-delabeling 28% vs. post-delabeling 1.2%, p < 0.001) and meropenem (13% vs. 2.4%, p = 0.022) significantly decreased while cefepime (24% vs. 50%, p = 0.001) and piperacillin-tazobactam (3.7% vs. 22%, p < 0.001) increased after delabeling. CONCLUSION: BLA-P led to 21% delabeling, which resulted in increased preferred Br-ABX and decrease in aztreonam/meropenem use among delabeled patients.
RESUMEN
Identifying the genetic architecture underlying adaptive traits is exceptionally challenging in natural populations. This is because associations between traits not only mask the targets of selection but also create correlated patterns of genomic divergence that hinder our ability to isolate causal genetic effects. Here, we examine the repeated evolution of components of the auxin pathway that have contributed to the replicated loss of gravitropism (i.e. the ability of a plant to bend in response to gravity) in multiple populations of the Senecio lautus species complex in Australia. We use a powerful approach which combines parallel population genomics with association mapping in a Multiparent Advanced Generation Inter-Cross (MAGIC) population to break down genetic and trait correlations to reveal how adaptive traits evolve during replicated evolution. We sequenced auxin and shoot gravitropism-related gene regions in 80 individuals from six natural populations (three parallel divergence events) and 133 individuals from a MAGIC population derived from two of the recently diverged natural populations. We show that artificial tail selection on gravitropism in the MAGIC population recreates patterns of parallel divergence in the auxin pathway in the natural populations. We reveal a set of 55 auxin gene regions that have evolved repeatedly during the evolution of the species, of which 50 are directly associated with gravitropism divergence in the MAGIC population. Our work creates a strong link between patterns of genomic divergence and trait variation contributing to replicated evolution by natural selection, paving the way to understand the origin and maintenance of adaptations in natural populations.

Human monkeypox (mpox) virus is a viral zoonosis that belongs to the Orthopoxvirus genus of the Poxviridae family, which presents with similar symptoms as those seen in human smallpox patients. Mpox is an increasing concern globally, with over 80,000 cases in non-endemic countries as of December 2022. In this review, we provide a brief history and ecology of mpox, its basic virology, and the key differences in mpox viral fitness traits before and after 2022. We summarize and critique current knowledge from epidemiological mathematical models, within-host models, and between-host transmission models using the One Health approach, where we distinguish between models that focus on immunity from vaccination, geography, climatic variables, as well as animal models. We report various epidemiological parameters, such as the reproduction number, R0, in a condensed format to facilitate comparison between studies. We focus on how mathematical modelling studies have led to novel mechanistic insight into mpox transmission and pathogenesis. As mpox is predicted to lead to further infection peaks in many historically non-endemic countries, mathematical modelling studies of mpox can provide rapid actionable insights into viral dynamics to guide public health measures and mitigation strategies.

The measurement of physiologic pressure helps diagnose and prevent associated health complications. From typical conventional methods to more complicated modalities, such as the estimation of intracranial pressures, numerous invasive and noninvasive tools that provide us with insight into daily physiology and aid in understanding pathology are within our grasp. Currently, our standards for estimating vital pressures, including continuous BP measurements, pulmonary capillary wedge pressures, and hepatic portal gradients, involve the use of invasive modalities. As an emerging field in medical technology, artificial intelligence (AI) has been incorporated into analyzing and predicting patterns of physiologic pressures. AI has been used to construct models that have clinical applicability both in hospital settings and at-home settings for ease of use for patients. Studies applying AI to each of these compartmental pressures were searched and shortlisted for thorough assessment and review. There are several AI-based innovations in noninvasive blood pressure estimation based on imaging, auscultation, oscillometry and wearable technology employing biosignals. The purpose of this review is to provide an in-depth assessment of the involved physiologies, prevailing methodologies and emerging technologies incorporating AI in clinical practice for each type of compartmental pressure measurement. We also bring to the forefront AI-based noninvasive estimation techniques for physiologic pressure based on microwave systems that have promising potential for clinical practice.

Production of bowel sounds, established in the 1900s, has limited application in existing patient-care regimes and diagnostic modalities. We review the physiology of bowel sound production, the developments in recording technologies and the clinical application in various scenarios, to understand the potential of a bowel sound recording and analysis device-the phonoenterogram in future gastroenterological practice. Bowel sound production depends on but is not entirely limited to the type of food consumed, amount of air ingested and the type of intestinal contractions. Recording technologies for extraction and analysis of these include the wavelet-based filtering, autoregressive moving average model, multivariate empirical mode decompression, radial basis function network, two-dimensional positional mapping, neural network model and acoustic biosensor technique. Prior studies evaluate the application of bowel sounds in conditions such as intestinal obstruction, acute appendicitis, large bowel disorders such as inflammatory bowel disease and bowel polyps, ascites, post-operative ileus, sepsis, irritable bowel syndrome, diabetes mellitus, neurodegenerative disorders such as Parkinson's disease and neonatal conditions such as hypertrophic pyloric stenosis. Recording and analysis of bowel sounds using artificial intelligence is crucial for creating an accessible, inexpensive and safe device with a broad range of clinical applications. Microwave-based digital phonoenterography has huge potential for impacting GI practice and patient care.

Plant rhizo-microbiome comprises complex microbial communities that colonize at the interphase of plant roots and soil. Plant growth-promoting rhizobacteria (PGPR) in the rhizosphere provide important ecosystem services ranging from the release of essential nutrients for enhancing soil quality and improving plant health to imparting protection to plants against rising biotic and abiotic stresses. Hence, PGPR serve as restoring agents to rejuvenate soil health and mediate plant fitness in the facet of changing climate. Though it is evident that nutrient availability in soil is managed through inter-linked mechanisms, how PGPR expedite these processes remain less recognized. Promising results of PGPR inoculation on plant growth are continually reported in controlled environmental conditions, however, their field application often fails due to competition with native microbiota and low colonization efficiency in roots. The development of highly efficient and smart bacterial synthetic communities by integrating bacterial ecological and genetic features provides better opportunities for successful inoculant formulations. This review provides an overview of the interplay between nutrient availability and disease suppression governed by rhizobacteria in soil followed by the role of synthetic bacterial communities in developing efficient microbial inoculants. Moreover, an outlook on the beneficial activities of rhizobacteria in modifying soil characteristics to sustainably boost agroecosystem functioning is also provided.

RESUMEN
Flavor is an expression of olfactory and gustatory sensations experienced through a multitude of chemical processes triggered by molecules. Beyond their key role in defining taste and smell, flavor molecules also regulate metabolic processes with consequences to health. Such molecules present in natural sources have been an integral part of human history with limited success in attempts to create synthetic alternatives. Given their utility in various spheres of life such as food and fragrances, it is valuable to have a repository of flavor molecules, their natural sources, physicochemical properties, and sensory responses. FlavorDB (http://cosylab.iiitd.edu.in/flavordb) comprises of 25,595 flavor molecules representing an array of tastes and odors. Among these 2254 molecules are associated with 936 natural ingredients belonging to 34 categories. The dynamic, user-friendly interface of the resource facilitates exploration of flavor molecules for divergent applications: finding molecules matching a desired flavor or structure; exploring molecules of an ingredient; discovering novel food pairings; finding the molecular essence of food ingredients; associating chemical features with a flavor and more. Data-driven studies based on FlavorDB can pave the way for an improved understanding of flavor mechanisms.

A new series of substituted-N-(3,4-dimethoxyphenyl)-benzoxazole derivatives 13a-13p was synthesized and evaluated in vitro for their COX (I and II) inhibitory activity, in vivo anti-inflammatory and ulcerogenic potential. Compounds 13d, 13h, 13k, 13l and 13n exhibited significant COX-2 inhibitory activity and selectivity towards COX-2 over COX-1. These selected compounds were screened for their in vivo anti-inflammatory activity by carrageenan induced rat paw edema method. Among these compounds, 13d was the most promising analogs of the series with percent inhibition of 84.09 and IC50 value of 0.04⯵M and 1.02⯵M (COX-2 and COX-1) respectively. Furthermore, ulcerogenic study was performed and tested compounds (13d, 13h, 13k, 13l) demonstrated a significant gastric tolerance than ibuprofen. Molecular docking study was also performed with resolved crystal structure of COX-2 to understand the binding mechanisms of newly synthesized inhibitors in the active site of COX-2 enzyme and the results were found to be concordant with the biological evaluation studies of the compounds. These newly synthesized inhibitors also showed acceptable pharmacokinetic profile in the in silico ADME/T analyses.

The present study was undertaken to study the impact of surgical menopause on oxidant and antioxidant status in relation to estrogen levels after 3 months of surgery. Total 130 women who had undergone total hysterectomy (TH) with or without bilateral salpingo-oophorectomy (BSO) were included in this study. The oxidant status was assessed by measuring plasma levels of malondialdehyde and antioxidant status was assessed by measuring superoxide dismutase, catalase, glutathione, glutathione peroxidase, estrogen, and Vitamin A, E and C levels. The malondialdehyde level was significantly increased (p < 0.05) in all women who underwent TH with or without BSO. Significant increased levels of superoxide dismutase were observed in women who underwent TH with BSO. The blood glutathione levels were significantly decreased in women after TH only but significantly increased in women who had undergone TH with BSO. The levels of estrogen, vitamin E and vitamin C were significantly decreased in women who underwent TH with BSO. The catalase, GPx and vitamin A did not differ significantly in all groups. The result suggests that surgical menopause is associated with oxidative stress which reiterates the fact that ovaries retain some function even after menopause.
RESUMEN
A series of N-(2-(4-chlorobenzyl)benzo[d]oxazol-5-yl)-3-substituted-propanamide (3a-3n) were synthesized and evaluated for their acute and chronic anti-inflammatory potential. The structure of the compounds was elucidated by elemental and spectral (IR, 1H NMR and MS) analysis. The synthesized compounds (at a dose of 20 mg/kg b.wt. p.o.) have shown their ability to provide 45.1-81.7% protection against carrageenan-induced paw edema, in comparison with diclofenac sodium (69.5%) and ibuprofen (64.7%). The most active compounds 3a, 3l and 3n were screened for chronic anti-inflammatory activity (cotton-pellet-induced granuloma) and to study their ulcerogenic activity. Compounds 3a, 3l and 3n showed 48.4%, 39.3% and 44.0% protection against cotton pellets-induced granuloma compared to diclofenac sodium (60.2%). The tested compounds were less ulcerogenic than the ibuprofen. Molecular modeling studies suggest that these compounds have strong interaction with the COX-2 enzyme, which is responsible for the activity.
RESUMEN
BACKGROUND: The aim of the study was to compare prefeed abdominal circumference (AC) and gastric residual volume (GRV) as a measure of feed intolerance in very-low-birth-weight infants (VLBW). METHODS: Eighty VLBW infants were randomized to 2 groups; feed intolerance was monitored by measuring either GRV group or prefeed AC group. The primary outcome was time to full enteral feeds (180 mL · kg · day). Other main outcome measures were feed interruption days, duration of parenteral nutrition, incidence of culture positive sepsis, necrotizing enterocolitis, mortality, and duration of hospital stay. RESULTS: The median (interquartile range) time to achieve full feeds was 10 (9-13) versus 14 (12-17.5) days in AC and GRV groups, respectively (Pâ<â0.001). Infants in AC group had fewer feed interruption days (0 [0-2] vs 2.0 [1, 5], Pâ<â0.001) and shorter duration of parenteral nutrition (Pâ<â0.001). The incidence of culture-positive sepsis in AC and GRV groups was 17.5% and 30 %, respectively (Pâ=â0.18). Duration of hospital stay and mortality were comparable in both the groups. CONCLUSIONS: Prefeed AC as a measure of feed intolerance in VLBW infants may shorten the time taken to achieve full feeds.

Background Physicians and the medical manufacturing industry (MMI) are closely associated and may have some form of financial or business arrangement. Research has highlighted that these interactions negatively impact physicians' prescribing behaviour. We tried to explore medical students' perspectives regarding these interactions. Methods We did a questionnaire-based survey to capture the demographic information and included five yes-or-no questions with two possible answers that probed the participants' awareness. Statements (26 Likert-style questions) describing various physician-industry interactions were formulated based on previous research. Excel was used to gather the data, and SPSS v 25.0® for Windows was used to analyse it. Frequencies and percentages (qualitative variables) and means and standard deviations were used to present descriptive statistics (quantitative variables). The associations between the independent variables and awareness were examined using chi-square test. Results About 40% of students knew doctors and MMI work together, but only 6% knew there were rules about accepting gifts from MMI. Eighty-four per cent of respondents felt free samples from MMI were an excellent way to learn about new products. The prevalence of awareness was higher in interns/housemen (51.6%) compared to medical students (35.9%). Most (43%) of the participants preferred an online database as a method of disclosure. Conclusions Our findings indicated students' knowledge gaps regarding ethical considerations and recommended guidelines regarding the relational dynamics of medical practitioners and MMI. Students should be taught appropriate conduct and best practices and must strive to develop skepticism towards MMI marketing claims. This may be achieved by implementing various educational interventions in the medical curriculum.

Background/Objective: Cannabis, one of the most widely used recreational drug in the United States, has had a significant surge in usage following its legalization in 1996. In recent years, there has been research into the physiological effects of cannabis on the gastrointestinal (GI) system. Our study aims to systematically examine the association between cannabis use and complications of gastroesophageal reflux disease (GERD). Materials and Methods: We queried the 2016-2020 National Inpatient Sample database to identify patient encounters with GERD. Patients with eosinophilic esophagitis or missing demographics were excluded. We compared patient demographics, comorbidities, and complications among cannabis users and nonusers. Multivariate logistic regression analysis was used to investigate the relationship between cannabis use and complications of GERD. Results: A total of 27.2 million patient encounters were included in the analysis, out of which 507,190 were cannabis users. Majority of the cannabis users were aged between 45-64 years (46.6%), males (57.4%), White (63.84%), and belonged to the lowest income quartile (40.6%). Cannabis users demonstrated a higher prevalence of esophagitis compared to nonusers (6.11% vs. 3.23%, p<0.001). However, they exhibited a lower rates of esophageal stricture (0.6% vs. 0.8%, p<0.001) and esophageal cancer (0.2% vs. 0.24%, p<0.001). After adjusting for confounding factors, cannabis users were noted to have higher odds of esophagitis (adjusted odds ratio [aOR]: 1.34, 95% confidence interval [CI]: 1.30-1.39, p<0.001). A lower odds of esophageal stricture (aOR: 0.88, 95% CI: 0.81-0.96, p=0.02) and esophageal cancer (aOR: 0.48,95% CI: 0.42-0.57, p<0.001) were noted. Conclusion: Our cross-sectional study using the nationally available database indicates an association between cannabis use and higher odds of esophagitis, along with lower odds of esophageal stricture and cancer. While these findings suggest a potential relationship between cannabis use and esophageal complications, it is limited in establishing causality. Therefore, further long-term studies are warranted to understand the mechanism behind this association and to determine if cannabis use has an impact on esophagus.
RESUMEN
AIM: This study aimed to assess the efficacy of hyaluronic acid (HA) gel injections in deficient papillae and record the effects for four weeks. MATERIALS AND METHODS: Fifteen deficient class 1 papilla sites according to Nordland and Tarnow classification were included. After scaling and root planing, 0.5 ml HA gel was injected into the papillae. Measurements of black triangle height (BTH) and black triangle area (BTA) from the contact point to the most coronal level of the visible papilla tip were done on the clinical photographs using ImageJ software at baseline, one week, and four weeks postoperatively, and a comparison was made. Descriptive data were examined using the mean and standard deviation (SD). Paired t-test was used for intragroup comparisons, with p-values <0.05 considered significant. All the data analysis was done using SPSS software version 25.0. RESULTS: There was a mean decrease in the BTA from baseline (0.54 mm2), one week (0.13 mm2), to four weeks (0.26 mm2) with a slight loss of papilla volume from the first week to the fourthweek, and this decrease in area was statistically significant. A mean decrease in the BTH throughout the follow-ups from baseline (1.36 mm) to the first week (0.30 mm) to the fourth week (0.73) was recorded with a slight loss of papilla volume from the first week to the fourthweek, and this decrease in height was also statistically significant (p < 0.05). However, the decrease in the BTA and BTH recorded was more from baseline to the first week as compared to baseline to the fourth week postoperatively. CONCLUSION: HA gel is an effective treatment for minimally invasive papilla augmentation, particularly in class I Nordland and Tarnow papilla deficits.
