ER-to-Golgi protein delivery through an interwoven, tubular network extending from ER.

Cellular versatility depends on accurate trafficking of diverse proteins to their organellar destinations. For the secretory pathway (followed by approximately 30% of all proteins), the physical nature of the vessel conducting the first portage (endoplasmic reticulum [ER] to Golgi apparatus) is unclear. We provide a dynamic 3D view of early secretory compartments in mammalian cells with isotropic resolution and precise protein localization using whole-cell, focused ion beam scanning electron microscopy with cryo-structured illumination microscopy and live-cell synchronized cargo release approaches. Rather than vesicles alone, the ER spawns an elaborate, interwoven tubular network of contiguous lipid bilayers (ER exit site) for protein export. This receptacle is capable of extending microns along microtubules while still connected to the ER by a thin neck. COPII localizes to this neck region and dynamically regulates cargo entry from the ER, while COPI acts more distally, escorting the detached, accelerating tubular entity on its way to joining the Golgi apparatus through microtubule-directed movement.

Immunosuppression by Mutated Calreticulin Released from Malignant Cells.

Mutations affecting exon 9 of the CALR gene lead to the generation of a C-terminally modified calreticulin (CALR) protein that lacks the KDEL endoplasmic reticulum (ER) retention signal and consequently mislocalizes outside of the ER where it activates the thrombopoietin receptor in a cell-autonomous fashion, thus driving myeloproliferative diseases. Here, we used the retention using selective hooks (RUSH) assay to monitor the trafficking of CALR. We found that exon-9-mutated CALR was released from cells in response to the biotin-mediated detachment from its ER-localized hook, in vitro and in vivo. Cellular CALR release was confirmed in suitable mouse models bearing exon-9-mutated hematopoietic systems or tumors. Extracellular CALR mediated immunomodulatory effects and inhibited the phagocytosis of dying cancer cells by dendritic cells (DC), thereby suppressing antineoplastic immune responses elicited by chemotherapeutic agents or by PD-1 blockade. Altogether, our results demonstrate paracrine immunosuppressive effects for exon-9-mutated CALR.

Outbreak of Invasive Serratia marcescens among Persons Incarcerated in a State Prison, California, USA, March 2020-December 2022.

Serratia marcescens is an environmental gram-negative bacterium that causes invasive disease in rare cases. During 2020-2022, an outbreak of 21 invasive Serratia infections occurred in a prison in California, USA. Most (95%) patients had a history of recent injection drug use (IDU). We performed whole-genome sequencing and found isolates from 8 patients and 2 pieces of IDU equipment were closely related. We also identified social interactions among patients. We recovered S. marcescens from multiple environmental samples throughout the prison, including personal containers storing Cell Block 64 (CB64), a quaternary ammonium disinfectant solution. CB64 preparation and storage conditions were suboptimal for S. marcescens disinfection. The outbreak was likely caused by contaminated CB64 and propagated by shared IDU equipment and social connections. Ensuring appropriate preparation, storage, and availability of disinfectants and enacting interventions to counteract disease spread through IDU can reduce risks for invasive Serratia infections in California prisons.

First complete remission favours haploidentical haematopoietic stem cell transplantation with post-transplant cyclophosphamide over cord blood transplantation in acute lymphoblastic leukaemia.

To assess the benefits of HLA-haploidentical haematopoietic stem cell transplantation using post-transplant cyclophosphamide (PTCy-haplo) relative to those of umbilical cord blood (UCB) transplantation in acute lymphoblastic leukaemia (ALL), we analysed 1999 patients (PTCy-haplo, 330; UCB, 1669), using the nationwide Japanese registry. PTCy-haplo was associated with a significantly higher relapse rate, but lower non-relapse mortality, which results in overall survival and disease-free survival, comparable to those of UCB. Among patients in CR1, PTCy-haplo showed a significantly higher survival than UCB regardless of the CD34+ cell dose. Our findings provide valuable insights into the donor selection algorithm in allogeneic HSCT for adult patients with ALL.

Hierarchical organization of the human ventral visual streams revealed with magnetoencephalography.

The hierarchical organization between 25 ventral stream visual cortical regions and 180 cortical regions was measured with magnetoencephalography using the Human Connectome Project Multimodal Parcellation atlas in 83 Human Connectome Project participants performing a visual memory task. The aim was to reveal the hierarchical organization using a whole-brain model based on generative effective connectivity with this fast neuroimaging method. V1-V4 formed a first group of interconnected regions. Especially V4 had connectivity to a ventrolateral visual stream: V8, the fusiform face cortex, and posterior inferior temporal cortex PIT. These regions in turn had effectivity connectivity to inferior temporal cortex visual regions TE2p and TE1p. TE2p and TE1p then have connectivity to anterior temporal lobe regions TE1a, TE1m, TE2a, and TGv, which are multimodal. In a ventromedial visual stream, V1-V4 connect to ventromedial regions VMV1-3 and VVC. VMV1-3 and VVC connect to the medial parahippocampal gyrus PHA1-3, which, with the VMV regions, include the parahippocampal scene area. The medial parahippocampal PHA1-3 regions have connectivity to the hippocampal system regions the perirhinal cortex, entorhinal cortex, and hippocampus. These effective connectivities of two ventral visual cortical streams measured with magnetoencephalography provide support to the hierarchical organization of brain systems measured with fMRI, and new evidence on directionality.

Smart plant disease net: Adaptive Dense Hybrid Convolution network with attention mechanism for IoT-based plant disease detection by improved optimization approach.

Plant diseases are rising nowadays. Plant diseases lead to high economic losses. Internet of Things (IoT) technology has found its application in various sectors. This led to the introduction of smart farming, in which IoT has been utilized to help identify the exact spot of the diseased affected region on the leaf from the vast farmland in a well-organized and automated manner. Thus, the main focus of this task is the introduction of a novel plant disease detection model that relies on IoT technology. The collected images are given to the Image Transmission phase. Here, the encryption task is performed by employing the Advanced Encryption Standard (AES) and also the decrypted plant images are fed to the pre-processing stage. The Mask Regions with Convolutional Neural Networks (R-CNN) are used to segment the pre-processed images. Then, the segmented images are given to the detection phase in which the Adaptive Dense Hybrid Convolution Network with Attention Mechanism (ADHCN-AM) approach is utilized to perform the detection of plant disease. From the ADHCN-AM, the final detected plant disease outcomes are obtained. Throughout the entire validation, the offered model shows 95% enhancement in terms of MCC showcasing its effectiveness over the existing approaches.

Phospholipid Scramblase 1 Localizes Proximal to Sphingomyelin Synthase Isoforms but Is Not Involved in Sphingomyelin Synthesis.

Ceramide (Cer) is synthesized de novo in the bilayer of the endoplasmic reticulum and transported to the cytosolic leaflet of the trans-Golgi apparatus for sphingomyelin (SM) synthesis. As the active site of SM synthase (SMS) is located on the luminal side of the Golgi membrane, Cer translocates to the lumen via transbilayer movement for SM synthesis. However, the mechanism of transbilayer movement is not fully understood. As the Cer-related translocases seem to localize near the SMS, the protein was identified using proximity-dependent biotin identification proteomics. Phospholipid scramblase 1 (PLSCR1), which is thought to act as a scramblase for phosphatidylserine and phosphatidylethanolamine, was identified as a protein proximal to the SMS isoforms SMS1 and SMS2. Although five isoforms of PLSCR have been reported in humans, only PLSCR1, PLSCR3, and PLSCR4 are expressed in HEK293T cells. Confocal microscopic analysis showed that PLSCR1 and PLSCR4 partially co-localized with p230, a trans-Golgi network marker, where SMS isoforms are localized. We established CRISPR/Cas9-mediated PLSCR1, PLSCR3, and PLSCR4 single-knockout cells and PLSCR1, 3, 4 triple knockout HEK293T cells. Liquid chromatography-tandem mass spectrometry revealed that the levels of species with distinct acyl chains in Cer and SM were not significantly different in single knockout cells or in the triple knockout cells compared to the wild-type cells. Our findings suggest that PLSCR1 is localized in the vicinity of SMS isoforms, however is not involved in the transbilayer movement of Cer for SM synthesis.

Python tools for structural tasks in chemistry.

In recent decades, the use of computational approaches and artificial intelligence in the scientific environment has become more widespread. In this regard, the popular and versatile programming language Python has attracted considerable attention from scientists in the field of chemistry. It is used to solve a variety of chemical and structural problems, including calculating descriptors, molecular fingerprints, graph construction, and computing chemical reaction networks. Python offers high-quality visualization tools for analyzing chemical spaces and compound libraries. This review is a list of tools for the above tasks, including scripts, libraries, ready-made programs, and web interfaces. Inevitably this manuscript does not claim to be an all-encompassing handbook including all the existing Python-based structural chemistry codes. The review serves as a starting point for scientists wishing to apply automatization or optimization to routine chemistry problems.

Integrative ATAC-seq and RNA-seq analysis associated with diabetic nephropathy and identification of novel targets for treatment by dapagliflozin.

Dapagliflozin (DAPA) are clinically effective in improving diabetic nephropathy (DN). However, whether and how chromatin accessibility changed by DN responds to DAPA treatment is unclear. Therefore, we performed ATAC-seq, RNA-seq, and weighted gene correlation network analysis to identify the chromatin accessibility, the messenger RNA (mRNA) expression, and the correlation between clinical phenotypes and mRNA expression using kidney from three mouse groups: db/m mice (Controls), db/db mice (case group), and those treated with DAPA (treatment group). RNA-Seq and ATAC-seq conjoint analysis revealed many overlapping pathways and networks suggesting that the transcriptional changes of DN and DAPA intervention largely occured dependently on chromatin remodeling. Specifically, the results showed that some key signal transduction pathways, such as immune dysfunction, glucolipid metabolism, oxidative stress and xenobiotic and endobiotic metabolism, were repeatedly enriched in the analysis of the RNA-seq data alone, as well as combined analysis with ATAC-seq data. Furthermore, we identified some candidate genes (UDP glucuronosyltransferase 1 family, Dock2, Tbc1d10c, etc.) and transcriptional regulators (KLF6 and GFI1) that might be associated with DN and DAPA restoration. These reversed genes and regulators confirmed that pathways related to immune response and metabolism pathways were critically involved in DN progression.

Effects of 1-week inpatient multidisciplinary care for chronic kidney disease prior to outpatient collaborative care.

BACKGROUND: Multidisciplinary care for Chronic Kidney Disease (CKD) has been reported to be effective in preventing deterioration of renal function and avoiding hemodialysis induction using a central venous catheter. METHODS: We included 171 patients who received dialysis at our department between October 2014 and June 2017. Patients were divided into two groups: an inpatient group who received inpatient multidisciplinary care for CKD (educational hospitalization) prior to outpatient collaborative care from their family physician and nephrologist, and a non-inpatient group who did not receive such care. We compared factors related to dialysis induction. RESULTS: There was no significant difference in eGFR between the groups at the start of observation. The mean time from the start of observation to dialysis induction (inpatient group vs. non-inpatient group; 40.8 ± 2.8 vs. 23.9 ± 3.0 months, respectively; P < 0.001) and the rate of hemodialysis induction using a central venous catheter (22.5 vs. 47.1%, respectively; P = 0.002) were significantly different between the groups. Survival analysis showed that the time to dialysis induction was significantly longer in the inpatient group (P = 0.0001). Multivariate analysis revealed that educational hospitalization (odds ratio = 0.30 [95% CI 0.13, 0.67]) was significantly associated with hemodialysis induction using a central venous catheter. CONCLUSION: Educational hospitalization prior to outpatient collaborative care is beneficial for preventing hemodialysis induction using a central venous catheter and postponing dialysis induction.

The association between embedded catheter implantation and hospitalization costs for peritoneal dialysis initiation: a retrospective cohort study.

BACKGROUND: Compared with the conventional peritoneal dialysis (PD) catheter insertion, embedding PD catheter implantation is one of the procedures for planned PD initiation. However, facilities where embedded PD catheter implantation is available are limited, and the impact of embedded PD catheter implantation on hospitalization cost and length of hospitalization is unknown. METHODS: This retrospective single-center cohort study included 132 patients with PD initiation between 2005 and 2020. The patients were divided into two groups: 64 patients in the embedding group and 68 patients in the conventional insertion group. We created a multivariable generalized linear model (GLM) with the gamma family and log-link function to evaluate the association among catheter embedding, the duration and medical costs of hospitalization for PD initiation. We also evaluated the effect modification between age and catheter embedding. RESULTS: Catheter embedding (ß coefficient - 0.13 [95% confidence interval - 0.21, - 0.05]) and age (per 10 years 0.08 [0.03, 0.14]) were significantly associated with hospitalization costs. Catheter embedding (- 0.21 [- 0.32, - 0.10]) and age (0.11 [0.03, 0.19]) were also identified as factors significantly associated with length of hospitalization. The difference between the embedding group and the conventional insertion group in hospitalization costs for PD initiation (P for interaction = 0.060) and the length of hospitalization (P for interaction = 0.027) was larger in young-to-middle-aged patients than in elderly patients. CONCLUSIONS: Catheter embedding was associated with lower hospitalization cost and shorter length of hospitalization for PD initiation than conventional PD catheter insertion, especially in young-to-middle-aged patients.

Clinical feasibility of post-contrast accelerated 3D T1-Sampling Perfection with Application-optimized Contrasts using different flip angle Evolutions (SPACE) with iterative denoising for intracranial enhancing lesions: a retrospective study.

BACKGROUND: Post-contrast T1-Sampling Perfection with Application-optimized Contrasts using different flip angle Evolutions (SPACE) is the preferred 3D T1 spin-echo sequence for evaluating brain metastases, regardless of the prolonged scan time. PURPOSE: To evaluate the application of accelerated post-contrast T1-SPACE with iterative denoising (ID) for intracranial enhancing lesions in oncologic patients. MATERIAL AND METHODS: For evaluation of intracranial lesions, 108 patients underwent standard and accelerated T1-SPACE during the same imaging session. Two neuroradiologists evaluated the overall image quality, artifacts, degree of enhancement, mean contrast-to-noise ratiolesion/parenchyma, and number of enhancing lesions for standard and accelerated T1-SPACE without ID. RESULTS: Although there was a significant difference in the overall image quality and mean contrast-to-noise ratiolesion/parenchyma between standard and accelerated T1-SPACE without ID and accelerated SPACE with and without ID, there was no significant difference between standard and accelerated T1-SPACE with ID. Accelerated T1-SPACE showed more artifacts than standard T1-SPACE; however, accelerated T1-SPACE with ID showed significantly fewer artifacts than accelerated T1-SPACE without ID. Accelerated T1-SPACE without ID showed a significantly lower number of enhancing lesions than standard- and accelerated T1-SPACE with ID; however, there was no significant difference between standard and accelerated T1-SPACE with ID, regardless of lesion size. CONCLUSION: Although accelerated T1-SPACE markedly decreased the scan time, it showed lower overall image quality and lesion detectability than the standard T1-SPACE. Application of ID to accelerated T1-SPACE resulted in comparable overall image quality and detection of enhancing lesions in brain parenchyma as standard T1-SPACE. Accelerated T1-SPACE with ID may be a promising replacement for standard T1-SPACE.

The Need to Rethink Harm Reduction for People Using Drugs Alone to Reduce Overdose Fatalities.

Background: During the ongoing opioid epidemic, Cuyahoga County (second largest in Ohio) reported overdose mortality rates (54/per 100,000) higher than the national average. Prior research demonstrates that people who use drugs often use alone but there is minimal research on people who died of overdose while using alone. The objective of this study is to examine sociodemographic, toxicologic, and injury characteristics, and emergency medical response to overdose decedents who died using drugs alone. Method: Data from the Cuyahoga County Medical Examiner's Office (2016-2020, N = 2944) on unintentional overdose deaths in adults was tabulated including socio-demographic, toxicologic, and injury-related information. Decedents using drugs alone were identified and compared to those not using alone via Chi-square and Fisher's exact tests. We further fit a multivariate logistic regression model to evaluate socio-demographic, toxicologic, and injury-related factors associated with increased odds of using alone. All results are reported with 95% confidence intervals. Result: Among decedents, 75% (n = 2205) were using drugs alone. Decedents using alone were more likely to be using drugs at home (p = 0.001) or be found dead at the scene (p < 0.001) and less likely to receive naloxone (p < 0.001) have other person/bystander, not using, present (p = 0.002). Using drugs at home (aOR = 1.61[1.19-2.20]) was associated with higher odds of using alone; and being married (aOR = 0.57[0.38-0.86]), having history of illicit drug use (aOR = 0.25[0.08-0.81]) and other person present, who was not using (aOR = 0.58[0.42-0.79]) were associated with lower odds of using alone. Conclusion: New harm reduction approaches targeting people using drugs alone are needed to reduce overdose deaths.

The impact of grazing activities and environmental conditions on the stability of alpine grassland ecosystems.

Globally, grazing activities have profound impacts on the structure and function of ecosystems. This study, based on a 20-year MODIS time series dataset, employs remote sensing techniques and the Seasonal-Trend decomposition using Loess (STL) algorithm to quantitatively assess the stability of alpine grassland ecosystems from multiple dimensions, and to reveal the characteristics of grazing activities and environmental conditions on ecosystem stability. The results indicate that only 5.77% of the area remains undisturbed, with most areas experiencing varying degrees of disturbance. Further analysis shows that grazing activities in high vegetation coverage areas are the main source of interference. In areas with concentrated interference, elevation and slope have a positive correlation with resistance stability, but a negative correlation with recovery stability. Precipitation and landscape diversity have positive effects on both resistance stability and recovery stability. Vegetation coverage and grazing intensity have a negative correlation with resistance stability, but a positive correlation with recovery stability. This highlights the complex interactions between human activities, environmental factors, and ecosystem stability. The findings emphasize the need for targeted conservation and management strategies to mitigate disturbances to ecosystems affected by human activities and enhance their stability.

Assessment of antimicrobial drugs employed at government-operated hospitals in central and northern provinces of Iraq.

OBJECTIVE: Aim: To document the clinical patterns of antibiotic prescriptions in government hospitals, where the majority of physicians possess a degree-based training. PATIENTS AND METHODS: Materials and Methods: A Retrospective cross section study carried out between 1/7/2022 and April 2023 that enrolling 300 patients from governmental hospitals from different provinces of Central and northern Iraq. The research form contained 15 fields divided into three sections. The first section contains social information such as age, gender, field of work, Residence and education. The second part consists of diagnosis and lab. Finding. The third part related to antibiotic uses: Number of AB prescribed, duration of using, type of use, route of administration, AB interaction, dose administration of AB, indication of Ab, and Class of AB. RESULTS: Results: A total of 300 eligible patients, 165 patients (55.0%) were male and 135 (45.0%) were female, patients were <20 years ages were 117 (39.0%), 25 (8.3%) from the 20-29 years age group, 40-49 years ages were 28 (9.3%) and >50 years ages were 105 (35.0%) were which belong to the pediatric population. The 198 patients (66.0%) were used cephalosporins and 106 (53.5%) of them used alone. A 13-19% percentage of patients had used penicillin, carbapenem, anti-fungal, and aminoglycoside in combination form. CONCLUSION: Conclusions: The implementation of clinical guidelines, the provision of direct instruction, and the regular dissemination of antibiogram data have the potential to encourage a more judicious consumption of antibiotics.

[Comparative evaluation of the accuracy of 3D TMJ analysis performed by different methods of processing computed tomograms]. / Sravnitel'naya otsenka tochnosti 3D-analiza elementov visochno-nizhnechelyustnogo sustava, vypolnennogo raznymi sposobami obrabotki komp'yuternykh tomogramm.

OBJECTIVE: The aim of this study. Comparison of the accuracy of segmentation of TMJ elements in different ways and assessment of the suitability of the data obtained for the diagnosis of TMJ dysfunction. MATERIALS AND METHODS: To study the segmentation of the bone elements of the TMJ (articular fossa, head of the LF), 60 computed tomograms of the maxillofacial region of patients were randomly selected in various ways (archival material). In group 1, the results of CT processing by AI diagnostics algorithms (Russia) were collected; in group 2, the results of CT processing based on the semi-automatic segmentation method in the Avantis3D program. The results of CT processing by Avantis3D AI algorithms (Russia) with different probability modes - 0.4 and 0.9, respectively, were selected for the third and fourth groups. Visually, the coincidence of the contours of the LF heads and articular pits isolated using different methods with their contours on all possible sections of the original CT itself was evaluated. The time spent on TMJ segmentation according to CT data was determined and compared using the methods described above. RESULTS: Of the 240 objects, only 7.5% of the cases showed a slight discrepancy between the contours of the original CT in group b1, which was the lowest of all. A slight discrepancy in the TMJ contours to be corrected is characteristic of the semi-automatic method of segmentation by optical density was detected in 50.4% (group 2). The largest percentage of significant errors not subject to correction was noted in the first group, which made it impossible to perform a full 3D analysis of the TMJ, and the smallest in the second and fourth. The magnitude of the error in determining the width of the articular gap in different groups is comparable to the size of one voxel per CT. When segmentation is carried out using AI, the difference between segmented objects is close to zero values. The average time spent on TMJ segmentation in group 1 was 10.2±1.23 seconds, in group 2 - 12.6±1.87 seconds, in groups 3 and 4 - 0.46±0.12 seconds and 0.46±0.13 seconds, respectively. CONCLUSION: The developed automated method for segmenting TMJ elements using AI is obviously more suitable for practical work, since it requires minimal time, and is almost as accurate as other methods under consideration.

Sepsis following acute pyelonephritis caused by Trueperella bernardiae: a case report and literature review.

BACKGROUND: Trueperella bernardiae is a coryneform, gram-positive bacterium that is a commensal of the skin and upper respiratory tract. It is treated as a contaminant and rarely causes infections. Blood, urine, and abscesses have been previously reported as the most common sites of infection. Infections caused by T. bernardiae are rarely reported in bedridden very old patients with reduced activities of daily living (ADL). In this report, we describe a case of sepsis due to acute pyelonephritis caused by T. bernardiae in a very old patient with impaired ADL. CASE PRESENTATION: A 94-year-old woman had a home visit from her local physician. She was bedridden and used diapers. On the day of admission, she presented with fever and dyspnea and was admitted with a diagnosis of sepsis associated with acute pyelonephritis. T. bernardiae was detected in blood and urine cultures; furthermore, multiple bacteria were detected in a urine culture. She was treated with ampicillin/sulbactam 3 g every 12 h on the day of admission. The fever was controlled, and inhaled oxygen 1 L/min via a nasal cannula was administered for dyspnea until hospitalization day 2. On hospitalization day 2, her fever resolved to 36 °C. Antimicrobials were de-escalated and changed to cephazolin and then to cephalexin on hospitalization days 9 and 16, respectively, and were continued until day 22. On hospitalization day 28, the urinary tract infection flared up; however, her fever resolved by hospitalization day 38 after the re-administration of antimicrobial agents. She was discharged on hospitalization day 60. CONCLUSIONS: We encountered a rare case of sepsis following acute pyelonephritis caused by T. bernardiae infection. When bedridden, diaper-using, very old patients present with urinary tract infections caused by multiple bacteria, the presence of rare opportunistic organisms, such as T. bernardiae, should be considered.

Clinical impact of catheter insertion for peritoneal dialysis on patient survival and catheter-related complications.

OBJECTIVES: The stepwise initiation of peritoneal dialysis (PD) using Moncrief and Popovich's technique (SMAP) for catheter insertion is recommended for the systemic introduction of PD and prevention of catheter-related infections. In this study, we investigated patient outcomes in patients who underwent insertion of a PD catheter with a direct method versus the SMAP method. METHODS: We enrolled 295 consecutive patients who underwent PD as a primary renal replacement therapy and underwent insertion of a PD catheter at our institute between 2006 and 2021. We retrospectively reviewed their data and investigated patient outcomes, including mortality and PD catheter-related complications. RESULTS: Median age at PD induction was 65 years in the direct insertion group and 65 years in the SMAP group (P = 0.80). The rate of PD introduction after emergency hemodialysis was significantly higher in the direct insertion group than in the SMAP group (P < 0.001). There was no significant difference in survival between the direct insertion and SMAP groups during the median follow-up period of 54 months (P = 0.12). Additionally, patients who transitioned to hemodialysis or kidney transplantation after PD showed significantly longer survival (P < 0.001). The incidence of PD catheter-related complications was not significantly different between the two groups. A body mass index ≥ 23 kg/m2 was an independent risk factor for peritonitis and exit-site infection (P = 0.006 and P = 0.011, respectively). CONCLUSIONS: Planned sequential renal replacement therapy including hybrid hemodialysis, complete hemodialysis, and kidney transplantation after PD is important for improving patient outcomes. PD catheter insertion by SMAP may not be mandatory in our clinical practice.

Factors associated with not ready to stop using substances among adults with an unmet treatment need: findings from the National Survey of Drug Use and Health 2015-2019.

Background: A better understanding of factors associated with not ready to stop using substances may inform provider engagement with clients who have an unmet treatment need.Objectives: This study explores how treatment barriers, the number of SUD symptoms, and types of substances used are associated with not ready to stop using substances among adults with an unmet treatment need.Methods: The data came from the 2015-2019 National Survey on Drug Use and Health. Eligible adults met DSM-IV criteria for substance abuse and dependence and reported an unmet need for treatment. Among our sample (N = 1,017), a majority self-identified as male (weighted 59.3%). We employed multivariable logistic regression to examine individual-level factors associated with not being ready to stop using substances.Results: About 38% of the respondents reported that they were not ready to stop using substances. Reporting access barriers (aOR = 0.44, 95% CI: 0.29, 0.68) and attitudinal barriers (aOR = 0.47, 95% CI: 0.28, 0.80) was associated with a lower odds of not ready to stop using. Each additional increase in SUD symptoms was associated with 23% higher odds of not being ready to stop using (aOR = 1.22, 95% CI: 1.12, 1.34). Having a diagnosis of alcohol and/or marijuana abuse or dependence was associated with higher odds of not being ready to stop using when compared to respondents without these diagnoses (aOR = 2.13, 95% CI: 1.33, 3.40; aOR = 1.82 95% CI: 1.11, 2.99).Conclusion: Not ready to stop using substances may be impacted by the type of SUD, number of SUD symptoms, and certain barriers like access and attitude to care.
