The study was conducted at the Regional Horticultural Research Station of ASPEE College of Horticulture, Navsari Agricultural University, Gujarat, India to see the impact of organic seed priming on germination and viability of Khirni (Manilkara hexandra) seeds. The experiment following a Completely Randomized Design was implemented with four replications, featuring five diverse treatments: 3% solution of cow dung solution, 3% concentration cow urine solution, 3% Bijamrut, 3% Amritpani and water (control). The seeds treated with 3% Bijamrut for 72 hours had the highest germination and survival rates and were quickest to germinate. In addition, the best results were obtained for key growth metrics such as leaf area ratio, leaf area index, crop growth rate, emergence rate index and Bartlett’s rate index. The results show that Bijamrut is effective for both early growth and general vigour of Khirni seedlings and should therefore be considered to improve the establishment of Khirni seedlings.

Maturity at harvest is crucial for determining the quality of apricot fruit, a highly perishable crop with limited storage potential. The study aims to extend the storage life and preserve the quality of "Amal" apricots through various pre-harvest treatments. Pre-harvest application of spermidine at 1 mmol, salicylic acid at 1 mmol and sodium nitroprusside at 25µm were done at 15 or 30 days before harvesting. The treated fruits were packed and stored for up to 7 weeks at 5°C and 90–95 % R.H.; fruit quality parameters were evaluated at harvest and every 7 weeks. Results showed that weight loss, total soluble solids, maturity index, total sugars content, respiration rate and total carotenoids increased whereas, firmness, total acidity, and total phenols, decreased by increasing storage periods. The obtained results showed the efficacy of pre-harvest spermidine treatment followed by salicylic acid and then sodium nitroprusside in delaying fruit maturation and maintaining fruit quality. The study suggests that these treatments might be promising for maintaining apricot fruit quality and extending storage life and marketing of apricot.

The dominant urbanization and work environment, which have imposed stress on individuals and isolated them from nature, prompted this research into alleviating such stress through therapeutic horticulture interventions. The participant’s stress levels, engagement with nature, and socio-demographic status were documented by questionnaires and subjective feedback. The natural and simulated environments serve as interventional methods to stimulate the sensory aspects of urban dwellers through visual, aural, gustatory, tactile, and olfactory therapies. The garden configuration, virtual reality devices, fragrant oils, plant-derived beverages, and infinity walking configurations barefoot constitute the intervention measures. The horticulture interventions, both in natural and artificial environments, significantly reduced urban stress levels, yielding a mean value of 17.6±4.44, in contrast to the pre-test value of 20.8±4.14. The inclusion of nature in the self-scale score demonstrates a positive increase from 3.3±1.78 in the pre-test to 5.46±1.07 in the post-test. The Wilcoxon signed-rank test was employed to determine the disparity between the two methods of horticultural therapy. The efficacy of natural and simulated methods for horticulture interventions demonstrated a significantly higher ranking for the natural approach, with a significance level of 1%. The paired t-test was employed to compare the differences between pre-test and post-test data for natural and simulated therapy. The findings indicate that despite residing in a technologically advanced society, there is a preference for the natural world over the simulated one.

The genetic diversity of acid lime was analyzed across one hundred genotypes in twelve West Bengal districts, using 22 quantitative characters for characterization. The data was statistically processed for descriptive, hierarchical cluster, discriminate, correlation and principal component analysis. Descriptive analysis revealed a prominent variation in all quantitative characters among different lime collections, with wide variations recorded in eleven quantitative characters (fruit weight, rind thickness, vesicle length, juice weight, juice volume, juice percentage, number of seeds per fruit, seed weight, seed length, seed width and non-reducing sugars). Ward’s cluster analysis divided 100 lime genotypes into 5 clusters. Canonical discriminant function revealed that the major characters responsible for such clustering were fruit weight, vesicle length, seed length and seed width. PCA resulted in 9 components with a cumulative variance of 78.40 %. The biplot clarified the relation between genotypes and variables and the fruit characters distributed in the biplot contributed a considerable role to the differentiation of acid lime genotypes.

Crown rot disease in banana caused by the fungus Lasiodiplodia brasiliensis and Lasiodiplodia theobromae is one of the major post-harvest diseases causing a massive loss in the economic yield of banana. Isolates of Lasiodiplodia brasiliensis and Lasiodiplodia theobromae were isolated from infected fruits and were characterized based on their morphological and molecular characteristics. The isolates produced mustard seed-like pycnidia with conidia after 15 days after inoculation (DAI) and chlamydospore was observed after 16 DAI. The immature conidia were hyaline, aseptate, thin-walled and cylindrical to sub-ovoid in shape which became brown with central transverse septum at maturity. The isolates were sequenced and submitted in NCBI gene bank and were assigned with accession no. OQ921841 and OR764951. Further, the evolutionary relationships of the pathogen isolates were studied concerning different related genera and species of Lasiodiplodia.

The high labor requirements and inherent risk of traditional harvesting and pruning of tall trees like coconut and mango make them difficult to harvest and prune. Mechanized machines do exist, but they are too heavy, too expensive, and unsuitable for Indian marginal farmers with small landholdings, which reduces productivity, efficiency, and worker safety. A tractor-mounted hydraulic ladder was evaluated for harvesting coconut and mango under field conditions to address these challenges. The ladder can rotate 360 degrees and covers up to four trees with simple directional control. Trees up to 12 meters tall can be harvested, pruned, and sprayed. Harvesting efficiencies of 75-81% for coconut and 76-80% for mango were recorded in field evaluations. Operational costs for coconut are Rs. 439 per hour and Rs. 530 per h for mango, and the ladder can harvest 7-9 coconut trees per hour. This system offers a feasible, low-cost solution for small and marginal farmers who struggle with the use of traditional and expensive machinery.

Cassava is a starchy root crop used as food, feed and for industrial purposes. Antibiotic resistance genes are used as a marker for the selection of transformed cells from non-transformed cells in genetic engineering. The optimum concentration of selective antibiotics is crucial for the effective transformation and regeneration of transformed plants. The current study aimed to determine the optimal cytotoxic concentration of hygromycin for screening both transformed and non-transformed calli. The embryogenic calli were subjected to particle bombardment using the binary vector pCAMBIA 1305.1, which included the GUS reporter gene and the hptII gene. Hygromycin was added to the callus induction and regeneration medium at 0, 25, 50, 75, and 100 mg L-1 concentrations to identify the optimal selective concentration. Results indicated that 50 mg L-1 of hygromycin inhibited non-transformed calli and maintained the health of transformed calli. This concentration provided a sufficient amount of selective pressure with minimal cytotoxic effects, thus serving as the optimal level for distinguishing transformed cells in the cassava genetic transformation system.

The present study focused on the development and analysis of edible film using corn starch (CS), raw banana starch (BS) and taro root starch (TS). The starch was extracted from raw material and was evaluated for bulk density, tapped density, water-holding capacity, oil-holding capacity, dispersibility and colour analysis. Edible films were developed from as such starch namely, (CS, TS, BS) and different blending of starches, namely CBS 40:60, CBS 50:50, CTS 40:60, and CTS 50:50, by casting method using sorbitol as a plasticizer. The developed films were analyzed for thickness, solubility, transparency, colour, tensile strength, elongation at break, Young’s modulus, and Fourier-transform infrared spectroscopy (FTIR). The starch analysis revealed significant variation in bulk density, tapped density, water and oil holding properties, dispersibility, and brightness, in order corn starch> raw banana starch> taro root starch. The thickness of developed edible films ranged from 0.180 mm to 0.215 mm, and solubility from 32.756 to 72.453%. Among all the developed films, CBS 50:50 film had significantly higher transparency (0.678) after corn starch film (0.908), whereas, taro root starch-based film had the lowest transparency (0.388). The blending of raw banana starch with corn starch showed better mechanical properties among the developed films. Overall, the CBS 50:50 blend demonstrated the most favourable properties for edible film and holds great potential for use in biodegradable, edible packaging solutions.

The study, conducted at the Department of Plantation, Spices, Medicinal, and Aromatic Crops, College of Agriculture, Vellayani, aimed to assess the impact of foliar application of chitosan on photosynthetic performance in drought-stressed long pepper (Piper longum L.). Two concentrations of chitosan (0.5 and 1 g L-1) were applied to drought stress (irrigated at 60 and 75 % field capacities) and photosynthetic parameters were observed. Chitosan-treated plants, particularly at 1 g L-1 concentration, exhibited significantly higher relative water content, stomatal density, photosynthetic efficiency, transpiration rate, stomatal conductance, and water-use efficiency. Chitosan-treated plants also showed improved chlorophyll fluorescence parameters, chlorophyll content, and biomass yield compared to untreated controls. These findings suggest the potential of chitosan as a bio-elicitor against abiotic stresses in long pepper, warranting further research in this area.

A field experiment was carried out to study the effect of salicylic acid and kinetin on morpho-physiological, floral dynamics, and seed yield in salvia (Salvia splendens) at Banaras Hindu University Varanasi, Uttar Pradesh, India during 2021-22. A randomized block design (RBD) with three replications was used in the experiment. The treatments consisted of varying concentrations of salicylic acid (10 ppm, 20 ppm, 30 ppm, and 40 ppm) and kinetin (5 ppm, 10 ppm, 15 ppm, and 20 ppm) and a control of water spray only. Vegetative growth, flowering, and seed yield parameters were observed at 60 and 90 days after treatment (DAT). The ornamental value of plants was determined largely by plant growth regulators. Results showed that a 15 ppm kinetin spray enhanced plant height (75.34 cm) and plant spread (48.91 cm) at 90 DAT. Salicylic acid at 20 ppm gave the highest number of flower spikes per plant (93.33), number of flowers per plant (1746.00) and fresh weight of flowers (3.57 g). In addition, seed yield per plant (17.39 g) and test weight (2.94 g) were highest at 20 ppm salicylic acid. This study will help researchers understand how kinetin and salicylic acid affect plant growth.

Small cardamom (Elettaria cardamomum Maton) is one of the most important spice crops in India, cultivated for its economic, culinary and medicinal values. Leaf blight incited by Colletotrichum gloeosporioides is a serious threat to the cultivation of cardamom in India. In the present study, an attempt was made to isolate and characterize the pathogen both morphologically and on molecular basis. Significant variations were observed in twenty isolates for conidial dimensions, the length of conidia ranged from 7.8-21.5 ?m. The width of the conidia ranged from 3.3 to 7.8 ?m. Isolate CD14 recorded the highest width of conidium (7.8 ?m) and the lowest width was observed in CD8 isolate (3.3 ?m). Variation was also observed in size and lobes, length and width of appressoria produced by the pathogen. Differential reaction of isolates to three varieties revealed that CD5, CD8 and CD7 are highly virulent based on lesion area. Molecular characterization with RAPD, SSR and ISSR primers showed that RAPD and SSR markers are not linked to any characters of pathogen but ISSR primers showed linkage to the virulence of the pathogen.

Peat water is raw water which is used as a source of clean water by the people of Pekanbaru. However, after testing according to the Regulation of the Minister of Health of the Republic of Indonesia for clean water standards No. 416/MENKES/PER/IX/1990 the results of measuring the color and turbidity value of peat water are above the quality standards, namely 219 TCU and 15.1 NTU. This value is very far from the color and turbidity quality standards with respective concentrations of 15 TCU and 5 NTU. Therefore, in this research, an adsorption process was carried out using an adsorbent from Patin bone waste (Pangasius sp.) typical of Riau province by utilizing a physical activation process to open pores and help facilitate absorption. The variable used in this research were adsorbent mass and stirring speed. For adsorbent mass there was a variation of 0.1; 0.3; 0.5; and 0.7 grams while the stirring speed was 50, 100, and 150 rpm with a stirring time of 120 minutes and each sample had a particle size of 100 mesh. The results of this adsorption process obtain the best efficiency value at Patin bone mass of 0.7 grams with a stirring speed of 100 rpm. The color reduction efficiency reached 96.35%, namely 8 TCU, while the turbidity reduction efficiency at Patin bone mass of 0.7 grams with a stirring speed of 100 rpm reached 92.72%, namely 1.1 NTU.

Pendidikan merupakan salah satu faktor utama dalam menciptakan mobilitas sosial dan meningkatkan kualitas hidup individu. Namun, latar belakang sosial seseorang, termasuk status ekonomi, budaya, dan lingkungan geografis, memiliki pengaruh signifikan terhadap kesempatan pendidikan yang dapat diakses. Artikel ini bertujuan untuk menganalisis bagaimana faktor-faktor sosial tersebut memengaruhi kesempatan pendidikan dan mengidentifikasi kesenjangan yang ada di dalamnya. Menggunakan perspektif teori struktural fungsionalisme dan teori konflik, artikel ini menunjukkan bahwa ketimpangan sosial dalam pendidikan bukan hanya disebabkan oleh faktor individu, tetapi juga oleh struktur sosial yang ada. Selain itu, faktor budaya dan lingkungan geografis turut memperburuk ketimpangan pendidikan, khususnya di daerah terpencil dan bagi keluarga dengan status ekonomi rendah. Artikel ini juga menawarkan solusi untuk mengurangi kesenjangan pendidikan, antara lain dengan merancang kebijakan yang lebih inklusif dan meningkatkan akses pendidikan di daerah-daerah yang kurang berkembang.

Beyond z = 8, we observe a significant deviation (∼0.27 dex) in FMR, consistent with recent JWST findings. We also integrate Cosmic Evolution Early Release Science (135 galaxies) and JADES (47 galaxies) samples with our data to study the metallicity evolution with redshift in a combined sample of 263 galaxies, revealing a decreasing metallicity trend with a slope of 0.067 ± 0.013, consistent with IllustrisTNG and EAGLE but contradicting the FIRE simulations.

The structure and chemistry of the dusty interstellar medium (ISM) are shaped by complex processes that depend on the local radiation field, gas composition, and dust grain properties. Of particular importance are polycyclic aromatic hydrocarbons (PAHs), which emit strong vibrational bands in the mid-infrared, and play a key role in the ISM energy balance. We recently identified global correlations between PAH band and optical line ratios across three nearby galaxies, suggesting a connection between PAH heating and gas ionization throughout the ISM. In this work, we perform a census of the PAH heating–gas ionization connection using ∼700,000 independent pixels that probe scales of 40–150 pc in 19 nearby star-forming galaxies from the PHANGS survey. We find a universal relation between

log

PAH(11.3 μm/7.7 μm) and

log

([S ii]/Hα) with a slope of ∼0.2 and a scatter of ∼0.025 dex. The only exception is a group of anomalous pixels that show unusually high (11.3 μm/7.7 μm) PAH ratios in regions with old stellar populations and high starlight-to-dust emission ratios. Their mid-infrared spectra resemble those of elliptical galaxies. Active galactic nucleus hosts show modestly steeper slopes, with a ∼​​​​​​10% increase in PAH(11.3 μm/7.7 μm) in the diffuse gas on kiloparsec scales. This universal relation implies an emerging simplicity in the complex ISM, with a sequence that is driven by a single varying property: the spectral shape of the interstellar radiation field. This suggests that other properties, such as gas-phase abundances, gas ionization parameter, and grain charge distribution, are relatively uniform in all but specific cases.

In this paper, we use random forest in combination with the evolutionary grid from PARSEC 1.2S to determine M, L, t, and initial mass (M
i) for early-type main-sequence stars (T
eff ≥ 7000 K) as identified from the LAMOST survey. The convex hull algorithm is employed to select the main-sequence stars. The results demonstrate that the prediction precision is 32% and 9% for L and M, respectively, which is comparable to that achieved by fitting evolutionary tracks. Furthermore, the predicted L also aligns with Gaia’s observations, with a relative difference of 36%. The prediction for t is relatively less accurate, indicating a difference of 0.44 Gyr for two components in wide binaries. This discrepancy is due to the inconsistent metallicity measurements. For the two sets of atmospheric parameters we used, the relative differences in L, M, t, and M
i are 29%, 7%, 36%, and 7%, respectively. The influence of metallicity on these parameters is analyzed, with the conclusion that metallicity has the greatest impact on t. Consequently, two catalogs are presented, which could be useful for studying stellar populations such as the luminosity function and initial mass function of early-type stars.

We present a new photometric pipeline for the detection of pre-supernova (pre-SN) emission in the Young Supernova Experiment (YSE) sky survey. The method described is applied to SN 2020tlf, a type II SN with precursor emission in the last ~100 days before first light. We re-analyze the YSE griz-band light curves of SN 2020tlf and provide revised pre-explosion photometry that includes a robust list of confident detection and limiting magnitudes. Compared to the results of W. V. Jacobson-Galán et al., this new analysis yields fewer total r/i/z-band pre-SN detections at phases >−100 days. Furthermore, we discourage the use of the blackbody modeling of the pre-explosion spectral energy distribution, the pre-SN bolometric light curve and the blackbody model parameters presented in W. V. Jacobson-Galán et al. Nevertheless, binned photometry of SN 2020tlf confirms a consistent progenitor luminosity of ~1040 erg s−1 before explosion.

Published: January 2025

Postoperative pseudomeningocele is a rare, but still existing, complication after spinal surgeries. It may be asymptomatic or presented with back pain, radicular pain or headaches. Many pseudomeningoceles resolve spontaneously, others require revision surgery with dural repair. We present a female patient who underwent duroplasty treatment for a massive postoperative lumbar pseudomeningocele measuring 22.57 cm in length after broad laminectomy. A 71-year-old female with previous thoracolumbar T10-L5 instrumentation surgery, underwent a L2-5 broad laminectomy due to severe canal stenosis at the L2-5 level. Intraoperatively, an accidental spotted durotomy occurred at the level of L4-5. Primary repair was not feasible, so artificial dura was placed. Postoperatively the patient presented with cerebrospinal fluid (CSF) leak, which was treated with external lumbar drain and bedrest. Three months later, our patient presented to our outpatient clinic with a large 15 cm long bulging mass at the surgical site without any neurological deficit. A lumbar CT scan was conducted and a gigantic lumbar pseudomeningocele of 22.57 cm length and 6.29 cm width from the level of T11 to S2 was observed. We performed a revision surgery with duroplasty and there was no recurrence of CSF leak or pseudomeningocele after 7 months follow-up.

Pseudomeningoceles are rare post-operative complications. Although treatment options are controversial, they should be recognized soon enough in order to avoid central nervous infections, neurological deficits and further comorbidities.

Published: January 2025

DRESS (Drug Reaction with Eosinophilia and Systemic Symptoms) syndrome is a severe systemic drug reaction characterized by a latent period of several weeks following the initiation of drug therapy. Among the most well-known causative agents is allopurinol, commonly prescribed for managing asymptomatic gout. Allopurinol-induced DRESS syndrome is associated with high mortality rates and significant long-term sequelae. This report details the case of an elderly female patient who presented with an extensive rash covering her trunk and extremities which was concurrent with her use of allopurinol. The condition progressed to renal impairment but showed significant improvement upon cessation of the drug and administration of high-dose corticosteroids. This case aims to shed light on one of the most underrecognized types of systemic drug reactions, hoping to raise awareness about this rare yet serious complication of one of the most widely prescribed drugs.

Published: January 2025

Here we describe the first detected VIM-2-producing representative of Pseudomonas putida group – Pseudomonas kurunegalensis from the largest Bulgarian hospital – St George University Hospital in Plovdiv.

A 59-year-old female patient with right-sided lung abscess was hospitalized in the Second Clinic of Thoracoabdominal Surgery. She was repeatedly treated for pulmonary infections. Punctate from the abscess cavity was taken for microbiological investigation. Identification process and antimicrobial susceptibility were performed by Vitek 2. The species group P. putida was confirmed with MALDI-TOF system and whole genome sequencing defined it as P. kurunegalensis. Antibiotic susceptibility testing revealed susceptibility only to tobramycin and colistin. All phenotypic tests for carbapenemase and metallo-beta-lactamase (MBL) production were positive. Multiplex PCR was performed to search for nine common carbapenemase encoding genes whereas the variable region of the integron was determined by DNA sequencing. Molecular assays confirmed the presence of blaVIM-2 located within a typical Class I integron including also an aacA29b aminoglycoside N(6’)-acetyltransferase casette.

Despite P. putida not being a common pathogen, it still could survive in hospital conditions causing difficult-to-treat infections and becoming a source of resistant genes, including MBL-encoding genes.
Evaluation of psychosocial work environment among healthcare professionals in cardiac care units
Authors: Raycheva Ralitsa , Pavlova Pavlina , Dimova Rositsa
Published: January 2025

Introduction: Modern healthcare organizations and medical institutions depend on several factors, including the psychological environment as part of organizational culture. The psychological climate is multifaceted and difficult to quantify. The majority of scientific researchers agree that a good psychological climate supports teamwork, good communication, and a willingness to disclose errors and adverse events.

Aim: The objective of the study is to test a comprehensive and theory-based psychosocial work environment questionnaire and analyze the psychosocial climate among healthcare professionals in cardiac care units.

Material and methods: A survey-based cross-sectional study was done from November 2022 to March 2023 to analyze the psychological climate of cardiac ward professionals in South-Central Bulgarian hospitals. The study used the Bulgarian version of Koys and DeCotiis’ Inductive Measures of Psychological Climate (IMPC) questionnaire.

Results: The survey included 273 participants, 75.1% of whom were women (n=205). The respondents’ median age was 46, ranging from 35 to 54. They included 35.2% (n=96) with over 21 years of hospital experience. The highest proportion of in-hospital experience in a present hospital facility / present hospital unit was in the category 1 to 5 years – 27.5% (n=74) / 27.5% (n=74). The respondents were mostly registered nurses (40.3%, n=110). Specialist doctors were second at 23.8% (n=65), followed by paramedics at 14.7% (n=40), fellow doctors at 11.7% (n=32), and technical/medical personnel at 7.3% (n=20). Our study defines the psychological climate in cardiac units as having low pressure, moderate autonomy, recognition, and innovation, and high levels of trust, cohesion, support, and fairness.

Conclusion: The study focused on cardiac units, necessitating tailored approaches to address concerns across other wards. Establishing transparent and secure healthcare cultures, valuing employee input, and improving the psychological environment requires stakeholder collaboration.

Introduction: Technetium-99m (99mTc) is a short-lived nanocolloid nuclide widely used by oncologists to diagnose and identify cancer dissemination.

Aim: The aim of the current study was to develop the technique of radiopharmaceutical preparation (RPP) of Technefit99mTc aimed at examining sentinel lymph nodes (SLN) before surgery.

Materials and methods: We performed a series of trials (33 patients). Based on the information obtained from the portable gamma detector NEO2000 during surgery, a biopsy of the sentinel lymph nodes was carried out when RPP Technefit 99mTc accumulated in a specific lymph node.

Results: We determined maximum activities, volume, and peculiarities of administration of radioactive colloid Technefit99mTc in order to examine and perform the biopsy of SLN in the patients with malignant tumors. The most informative results in terms of scintigraphy images of sentinel lymph nodes were revealed in the first trial of the research, with all 5 cases (100%) showing positive results. The first trial included Technefit intradermal-hypodermal injection into one point above the tumor node, RPP activity of 75 to 200 mBq at a room temperature of 21°C, without preliminary anesthesia with Novocain solution.

Conclusion: We determined the most efficient dosages of activities, volume, and characteristics of radioactive colloid administration aimed at the examination and biopsy of sentinel lymph nodes using the radiopharmaceutical preparation Technefit 99mTc in patients with malignant tumors of different localizations, namely breast cancer and skin melanoma. In some cases, we did not find any signs of considerable lowering of the Technefit 99mTc activity, which shows that there is a very slow filtration of Technefit 99mTc through the pores of lymph capillaries.

The Effects of a Dedicated Education Unit on Baccalaureate Nursing Students' Clinical Judgment
Authors: Cooper Rhonda , Musallam Eyad , Warner Karen
Published: January 2025

Background

Nurse educators and students consider clinical learning experiences to be the best method for learning clinical judgment skills. Research on the relationship between dedicated education units (DEUs) and nursing students' clinical judgment skills is scarce. This study investigated the effects of a DEU on Bachelor of Science in Nursing (BSN) students' clinical judgment skills.

Method

A descriptive one-group pretest-posttest study assessed the effect of a DEU on BSN students' clinical judgment skills. Data were collected using the Lasater Clinical Judgment Rubric (LCJR).

Results

Students' essential clinical judgment skills (noticing, interpreting, responding, and reflecting) improved significantly. The DEU clinical experience helped students progress in clinical judgment behaviors from the developing stage to the accomplished stage using the LCJR.

Conclusion

The DEU clinical experience positively affected nursing students' clinical judgment. Further research is needed to assess how DEU models affect clinical judgment and transition to professional practice.

Published: January 2025

Attention-deficit/hyperactivity disorder (ADHD) is a treatable pediatric condition, but children with racial-ethnic minority backgrounds often do not receive timely or consistent treatment. Understanding how systemic racism impacts care and learning from families of color about their experiences can provide critical insights for improving clinical practice and engaging patients equitably in ADHD care. We interweave a mother's experience navigating ADHD care for her son with commentary from an interprofessional team about what clinicians can do for families to reduce the impact of systemic racism on care.
