Progression of Acute Lung Injury in Intratracheal LPS Rat Model: Efficacy of Fluticasone, Dexamethasone, and Pirfenidone
Authors: Kadam Anil H. , Schnitzer Jan E.
Published: November 2023

Introduction: We investigated the potential of LPS (10–300 µg/rat) administered intratracheally (i.t.) to induce reproducible features of acute lung injury (ALI) and compared the pharmacological efficacy of anti-inflammatory glucocorticoids and antifibrotic drugs to reduce the disease. Additionally, we studied the time-dependent progression of ALI in this LPS rat model. Methods: We conducted (1) dose effect studies of LPS administered i.t. at 10, 30, 100, and 300 μg/rat on ALI at 4 h timepoint; (2) pharmacological interventions using i.t. fluticasone (100 and 300 μg/rat), i.t. pirfenidone (4,000 μg/rat), and peroral dexamethasone (1 mg/kg) at 4 h timepoint; (3) kinetic studies at 0, 2, 4, 6, 8, 10, and 24 h post-LPS challenge. Phenotype or pharmacological efficacy was assessed using predetermined ALI features such as pulmonary inflammation, edema, and inflammatory mediators. Results: All LPS doses induced a similar increase of inflammation, edema, and inflammatory mediators, e.g., IL6, IL1β, TNFα, and CINC-1. In pharmacological intervention studies, we showed fluticasone and dexamethasone ameliorated ALI by inhibiting inflammation (>60–80%), edema (>70–100%), and the increase of cytokines IL6, IL1β, and TNFα (≥70–90%). We also noticed some inhibition of CINC-1 (25–35%) and TIMP1 (57%) increase with fluticasone and dexamethasone. Conversely, pirfenidone failed to inhibit inflammation, edema, and mediators of inflammation. Last, in ALI kinetic studies, we observed progressive pulmonary inflammation and TIMP1 levels, which peaked at 6 h and remained elevated up to 24 h. Progressive pulmonary edema started between 2 and 4 h and was sustained at later timepoints. On average, levels of IL6 (peak at 6–8 h), IL1β (peak at 2–10 h), TNFα (peak at 2 h), CINC-1 (peak at 2–6 h), and TGFβ1 (peak at 8 h) were elevated between 2 and 10 h and declined toward 24 h post-LPS challenge. Conclusion: Our data show that 10 μg/rat LPS achieved a robust, profound, and reproducible experimental ALI phenotype. Glucocorticoids ameliorated key ALI features at the 4-h timepoint, but the antifibrotic pirfenidone failed. Progressive inflammation and sustained pulmonary edema were present up to 24 h, whereas levels of inflammatory mediators were dynamic during ALI progression. This study’s data might be helpful in designing appropriate experiments to test the potential of new therapeutics to cure ALI.

Published: November 2023

Introduction: Comorbidities, such as gastroesophageal reflux disease (GERD), are common in patients with rhinosinusitis (RS). However, the link between RS and GERD has not been fully understood. This study aimed to investigate the causal relationship between GERD and acute (ARS) or chronic RS (CRS), providing references for the pathogenesis and management of RS. Methods: The data were obtained from the Integrative Epidemiology Unit Open GWAS project and FinnGen. A total of 972,838 individuals were included. The inverse variance-weighted (IVW) method was applied to obtain the primary results of the study. Weighted median, MR-Egger, and mode-based methods were used to determine the robustness of the results. Cochran’s Q statistic and MR-Egger method were applied to detect heterogeneity and pleiotrophy in instrumental variables (IVs). Other sensitivity analyses included MR-PRESSO and leave-one-out analysis. Results: The MR study showed that GERD was associated with an increased risk of CRS (OR: 1.36, 95% CI: 1.18–1.57, p < 0.001). The results of other analysis methods were broadly consistent with the IVW estimate. No heterogeneity was detected by Cochran’s Q test (p = 0.061) and MR-PRESSO (p = 0.074). No horizontal pleiotropy was shown in IVs (p = 0.700). GERD was also associated with an increased risk of ARS (OR: 1.31, 95% CI: 1.17–1.48, p < 0.001). Some analytical results were inconsistent with the IVW estimate. No heterogeneity and pleiotropy were observed. There was no sufficient evidence for a reverse causal effect of RS on GERD. Conclusion: Our study supported that GERD promoted the risk of CRS and may be a potential risk factor for ARS. This provides additional support for further investigation into the mechanisms of GERD on RS.

Published: November 2023

O presente artigo introduz e contextualiza a transcrição de uma correspondência do crítico de arte Mário Pedrosa ao empresário Francisco Matarazzo Sobrinho, enviada durante o processo que levou à autonomia das Bienais de São Paulo em relação à instituição que lhes deu origem, o Museu de Arte Moderna de São Paulo. Escrita no calor do momento, um dia após o encerramento da 6ª Bienal, que teve a direção artística de Pedrosa, a divulgação da correspondência ganha relevância na medida em que a compreendemos como uma peça dentro de um quebra-cabeças documental que releva as inúmeras articulações políticas realizadas para que o processo de autonomia das Bienais fosse levado à cabo. As consequências de tal processo, porém, eram percebidas de forma distinta por Pedrosa e Matarazzo Sobrinho, fato que pode ser lido nas entrelinhas do bilhete aqui apresentado.
Association between vaginal microbiome alteration and povidone iodine use during delivery
Authors: Li Hongping , Zhang Hongqin , Geng Linhua , Huang Hongli , Nie Chuan , Zhu Yuanfang
Published: November 2023

Background

The vaginal microbiome is a dynamic community of microorganisms in the vagina. Its alteration may be influenced by multiple factors, including gestational status, menstrual cycle, sexual intercourse, hormone levels, hormonal contraceptives, and vaginal drug administration. Povidone iodine has been used before delivery to reduce infection that may be caused by the ascendance of pathogenic and opportunistic bacteria from the vagina to the uterus. This study aimed to elucidate the impact of povidone iodine use during delivery on the vaginal microbiome.

Methods

This study enrolled a total of 67 women from maternity services in three hospitals. During the delivery process, we have applied povidone iodine in three doses such as low dose, medium dose, and high dose based on the amount of povidone iodine administered, thus, we studied the three groups of women based on the doses applied. Vaginal swab samples were collected both before and immediately after delivery, and the microbial communities were characterized using 16 S rRNA sequencing. The identification of differentially abundant microbial taxa was performed using ZicoSeq software.

Results

Before delivery, the vaginal microbiome was dominated by the genus Lactobacillus, with different percentage observed (86.06%, 85.24%, and 73.42% for the low, medium, and high dose groups, respectively). After delivery, the vaginal microbial community was restructured, with a significant decrease in the relative abundance of Lactobacillus in all three groups (68.06%, 50.08%, and 25.89%), and a significant increase in alpha diversity across all 3 groups (P < 0.01). Furthermore, as the dose of povidone iodine used during delivery increased, there was a corresponding decrease in the relative abundance of Lactobacillus (P < 0.01). Contrary, there was an increase in microbial diversity and the relative abundances of Pseudomonas (0.13%, 0.26%, and 13.04%, P < 0.01) and Ralstonia (0.01%, 0.02%, and 16.07%, P < 0.01) across the groups. Notably, some functional metabolic pathways related to sugar degradation were observed to have significant change with increasing use of povidone iodine.

Conclusion

Povidone iodine was associated with the vaginal microbiome alterations after parturition, and its significant change was associated to the dosage of povidone iodine administered. The escalation in iodine dosage was linked to a decrease in Lactobacilli abundance, and elevated prevalence of Pseudomonas and Ralstonia. There is a need for longitudinal studies to clearly understanding the effect of povidone iodine use on maternal and infant microbiome.

Published: November 2023

Background

The most common toxic side effect after chemotherapy, one of the main treatments for colorectal cancer (CRC), is myelosuppression.

Objective

To analyze the correlation between gut microbiota and leukopenia after chemotherapy in CRC patients.

Methods

Stool samples were collected from 56 healthy individuals and 55 CRC patients. According to the leukocytes levels in peripheral blood, the CRC patients were divided into hypoleukocytes group (n = 13) and normal leukocytes group (n = 42). Shannon index, Simpson index, Ace index, Chao index and Coverage index were used to analyze the diversity of gut microbiota. LDA and Student's t-test(St test) were used for analysis of differences. Six machine learning algorithms, including logistic regression (LR) algorithm, random forest (RF) algorithm, neural network (NN) algorithm, support vector machine (SVM) algorithm, catboost algorithm and gradient boosting tree algorithm, were used to construct the prediction model of gut microbiota with leukopenia after chemotherapy for CRC.

Results

Compared with healthy group, the microbiota alpha diversity of CRC patients was significantly decreased (p < 0.05). After analyzing the gut microbiota differences of the two groups, 15 differential bacteria, such as Bacteroides, Faecalibacterium and Streptococcus, were screened. RF prediction model had the highest accuracy, and the gut microbiota with the highest predictive value were Peptostreptococcus, Faecalibacterium, and norank_f__Ruminococcaceae, respectively. Compared with normal leukocytes group, the microbiota alpha diversity of hypoleukocytes group was significantly decreased (p < 0.05). The proportion of Escherichia-Shigella was significantly decreased in the hypoleukocytes group. After analyzing the gut microbiota differences of the two groups, 9 differential bacteria, such as Escherichia-Shigella, Fusicatenibacter and Cetobacterium, were screened. RF prediction model had the highest accuracy, and the gut microbiota with the highest predictive value were Fusicatenibacte, Cetobacterium, and Paraeggerthella.

Conclusion

Gut microbiota is related to leukopenia after chemotherapy. The gut microbiota may provide a novel method for predicting myelosuppression after chemotherapy in CRC patients.
Induction of tetraploids in Paper Mulberry (Broussonetia papyrifera (L.) L’Hér. ex Vent.) by colchicine
Authors: Lin Jiana , Zhang Bingnan , Zou Jintuo , Luo Zhen , Yang Hao , Zhou Peng , Chen Xiaoyang , Zhou Wei
Published: November 2023

Background

Broussonetia papyrifera (L.) L’Hér. ex Vent. has the characteristics of strong stress resistance, high crude protein content, and pruning tolerance. It is an ecological, economic, and medicinal plant. Polyploid plants usually perform better than their corresponding diploid plants in terms of nutrients, active substances, and stress resistance.

Results

In this study, the leaves, calli, and seeds of diploid B. papyrifera were used for tetraploid induction by colchicine. The induction effect of colchicine on B. papyrifera was summarized through the early morphology, chromosome count and flow cytometry. It was concluded that the best induction effect (18.6%) was obtained when the leaves of B. papyrifera were treated in liquid MS (Murashige and Skoog) medium containing 450 mg·L-1 colchicine for 3 d. The comparative analysis of the growth characteristics of diploid and tetraploid B. papyrifera showed that tetraploid B. papyrifera has larger ground diameter, larger stomata, thicker palisade tissue and thicker sponge tissue than diploid B. papyrifera. In addition, the measurement of photosynthetic features also showed that tetraploids had higher chlorophyll content and higher photosynthetic rates.

Conclusion

This study showed that tetraploid B. papyrifera could be obtained by treating leaves, callus and seeds with liquid and solid colchicine, but the induction efficiency was different. Moreover, there were differences in stomata, leaf cell structure and photosynthetic features between tetraploid B. papyrifera and its corresponding diploid. The induced tetraploid B. papyrifera can provide a technical basis and breeding material for the creation of B. papyrifera germplasm resources in the future.

Authors: Nong Qian , Lin Li , Xie Jinlan , Mo Zhanghong , Malviya Mukesh Kumar , Solanki Manoj Kumar , Wang Zeping , Song Xiupeng , Li Yangrui , Li Changning
Published: November 2023

Background

Drought limits crop growth and is an important issue in commercial sugarcane (Saccharum officinarum) production. Drought tolerance in sugarcane induced by endophytic nitrogen-fixing bacteria is a complex biological process that ranges from altered gene expression and cellular metabolism to changes in growth and productivity.

Results

In this study, changes in physiological features and transcriptome related to drought tolerance in sugarcane conferred by the Burkholderia endophytic nitrogen-fixing bacterial strain GXS16 were investigated. Sugarcane samples inoculated with GXS16 exhibited significantly higher leaf relative water content than those without GXS16 inoculation during the drought stages. Sugarcane treated with GXS16 had lower levels of H2O2 and higher levels of abscisic acid than sugarcane not treated with GXS16 in the non-watering groups. Transcriptomic analysis of sugarcane roots identified multiple differentially expressed genes between adjacent stages under different treatments. Moreover, both trend and weighted correlation network analyses revealed that carotenoid biosynthesis, terpenoid backbone biosynthesis, starch and sucrose metabolism, and plant hormone signal transduction strongly contributed to the drought-tolerant phenotype of sugarcane induced by GXS16 treatment. Accordingly, a gene regulatory network including four differentially regulated genes from carotenoid biosynthesis (crtB, crtZ, ZEP and CYP707A) and three genes from terpenoid backbone biosynthesis (dxs, dxr, and PCME) was constructed.

Conclusions

This study provides insights into the molecular mechanisms underlying the application of GXS16 treatment to enhance drought tolerance in sugarcane, which will lay the foundation for crop development and improve productivity.
“That’s probably how you would want care to be” - experiences of sick leave teams at a health center, a mixed method study
Authors: Hällås E. , Skoglund I. , Nordeman L.
Published: November 2023

Background

The health center where this study was performed the management wanted to test whether a sick leave team provided the physicians with better conditions for the task of assessing sick leave. The goals were to ensure the quality of the assessment of patients with sick leave needs and to improve the work environment. The aim of this study was to take part in the staff's experiences of having access to and working in sick leave teams and how the working method affected the number of sick leave patients and sick leave pattern.

Methods

A mixture of qualitative and quantitative methods. Two focus groups were conducted with a total of 11 participants. The head of the health center formed the focus groups, which consisted of 6 doctors, 3 district nurses, 1 rehab coordinator and 1 psychologist.

Aggregated sick leave data for full-time and part-time sick leave of more than 90, 180 and 360 days, respectively, were obtained and compiled at project start and end, and from the corresponding period 18 months before project start.

Results

The introduction of sick leave teams with physicians and rehabilitation coordinator for patients who turn to the health center for mental illness and / or musculoskeletal problems emerged three main categories from the analysis of the focus group discussions: working environment, clear roles and in-depth competence.

The total number of people who were on sick leave more than 365 days decreased by 27% between start and the end of the project, and the proportion of women increased by 11%.

Conclusions

The study shows that the complex task of sick leave can be perceived as positive by physicians with the support of teamwork. The working method is similar to that applied in occupational health care, where the physician is not alone with this task. This can also be a way to make primary care a more attractive workplace.
Digital support for quality assurance in 24-hour caregiving at home: a randomized controlled trial investigating the effects on quality of life and professional skills of paid 24h-caregivers
Authors: Haslinger-Baumann Elisabeth , Putz Peter , Hauser Carina , Kupka-Klepsch Elisabeth , Sturm Nadine , Werner Franz
Published: November 2023

Background

Regarding the care of older adults, 24-h home-care represents a cornerstone, with > 32,000 service users in Austria. Our research project 24hQuAALity aimed to develop and evaluate a distributed client-server software solution for the support and quality assurance of this home-care service. In this trial, we investigated the effects of this intervention on the quality of life and professional skills of paid 24h-caregivers in Austria.

Methods

The application used in our study comprises an e-learning platform, an integrated emergency management, networking opportunities, and an electronic care documentation system in the native language of the 24h-caregivers. The trial was conducted using a parallel three-arm study design to evaluate (i) a control group, which performed usual home care, (ii) a partial intervention group, which used the e-learning and networking platforms, and (iii) a full intervention group, which used the entire intervention (e-learning platform, networking platform, and digital care documentation). Primary self-reported outcomes were the standardized ASCOT for Carers score and a score based on responses to project-specific efficacy questions.

Results

Among the 110 24h-caregivers who were randomly classified into the three groups, ASCOT for Carers score data were available for 57 and 35 24h-caregivers at 5- and 9-month follow-up examinations, respectively. At 9 months, 24h-caregivers receiving any intervention rated the ASCOT for Carers score (not significantly) better than the controls (p = 0.05, ηp2 = 0.15), mainly in the domain “feeling encouraged and supported”. At 9 months, 24h-caregivers receiving any intervention rated the project-specific Efficacy score significantly better than the controls (p = 0.02, ηp2 = 0.20), mainly due to better ratings in the subitems “satisfaction with current docu”, “docu supports doing my job”, “ I’m well prepared for emergencies”, “my professional skills are adequate for doing my job”, and “communication with contacts”.

Conclusions

Providing e-learning and e-documentation devices to 24h-caregivers improved their care-related quality of life, mainly because they felt more encouraged and supported. Moreover, these interventions improved their self-perceived professional skills. As an extrapolation of findings, we found that these interventions could empower 24h-caregivers and improve the quality of home-care services provided by them.

Trial registration

Digital Support for Quality Assurance in 24-h Caregiving at Home was registered and posted on the ClinicalTrials.gov public website (ClinicalTrials.gov Identifier: NCT04581538).
The impact of immunosuppressive therapy on secondary infections and antimicrobial use in COVID-19 inpatients: a retrospective cohort study
Authors: Crook Peter , Logan Clare , Mazzella Andrea , Wake Rachel M. , Cusinato Martina , Yau Ting , Ong Yee-Ean , Planche Timothy , Basarab Marina , Bicanic Tihana
Published: November 2023

Background

Immunosuppressive therapies have become a cornerstone of the management of severe COVID-19. The impact of these therapies on secondary infections and antimicrobial prescribing remains unclear. We sought to assess antimicrobial use and the incidence of bacterial and fungal infections in patients with severe COVID-19, and to explore their associations with receipt of immunosuppressive therapies.

Methods

Our retrospective cohort study included 715 hospitalised, adult patients with severe COVID-19 admitted to St George’s Hospital, London, UK, during the first UK pandemic wave (1st March–10th June 2020). Co-infections (occurring within 48 h of admission) and secondary infections (≥ 48 h) were defined as a positive microbiological culture with supporting clinical, radiological or laboratory data to suggest true infection. Cox regression models with time-dependent covariates were used to explore the association between immunosuppressant use and secondary infection.

Results

Microbiologically confirmed co-infection occurred in 4.2% (n = 30) and secondary infection in 9.3% (n = 66) of the cohort (n = 715) and were associated with in-hospital mortality (48% vs 35%, OR 1.8, 95%CI 1.1–2.7, p = 0.01). Respiratory (n = 41, 39%) and bloodstream infections (n = 38, 36%) predominated, with primarily Gram-negative pathogens. 606 (84.7%) patients received an antimicrobial, amounting to 742 days of therapy per 1000 patient-days (DOTs). In multivariable models, receipt of high-dose steroids (≥ 30 mg prednisolone or equivalent) or tocilizumab was significantly associated with increased antimicrobial consumption (+ 5.5 DOTs, 95%CI 3.4–7.7 days) but not secondary infection (HR 0.56, 95%CI 0.26–1.18).

Conclusions

Bacterial and fungal infections in severe COVID-19 were uncommon. Receipt of steroids or tocilizumab was independently associated with antimicrobial consumption despite its lack of association with secondary infection. These findings should galvanise efforts to promote antimicrobial stewardship in patients with COVID-19.

Published: November 2023

Introduction

Multiple sclerosis (MS) is the most prevalent disease of the central nervous system that affects the behavioral characteristics and lifestyle of patients. This study aimed to determine the social stigma and its relationship with quality of life in people with MS referring to the Jahrom MS Association.

Method

This cross-sectional study was conducted on MS patients who are members of the MS Association of Jahrom City in Fars province, southern Iran in 2022. The samples were selected by census method. The number of participants remain 223 people. The data was collected using a standard two-part demographic and Multiple Sclerosis Quality of Life-54 (MSQOL-54) questionnaire and a researcher-made 20-question Social stigma questionnaire which validity and reliability were measured. Data analysis was done in a descriptive way (frequency, percentage, mean and standard deviation), univariate regression and multivariable linear regression. Data analysis was done using SPSS version 17 and at a significance level of less than 0.05.

Result

Based on univariate regression, marriage [B = 0.2, p-value = 0.004], physical health [B = 0.4, p-value < 0.001], emotional well-being [B = 0.4, p-value = 0.001], cognitive functioning [B = 0.4, p-value < 0.001], health distress [B = 0.5, p-value < 0.001] had a positive and significant relationship with patients’ quality of life. Duration of disease [B=-0.2, p-value < 0.001], physical role limitations [B=-0.4, p-value < 0.001], emotional role limitations [B=-0.5, p-value < 0.001], pain [B=-0.4, p-value < 0.001], energy [B=-0.3, p-value = 0.02], health perception [B=-0.3, p-value = 0.001], social functioning [B=-0.4, p-value < 0.001], sexual function [B=-0.3, p-value < 0.001], change in health [B=-0.3, p-value < 0.001], sexual function satisfaction [B=-0.3, p-value < 0.001] and social stigma [B=-0.3, p-value < 0.001] had a negative and significant relationship with patients’ quality of life (p < 0.05).

Conclusion

The study has emphasized the relationship between the extent and severity of symptoms and disorders with the quality of life of people with MS. The results of the study showed factors such as marriage, physical health and health distress have a positive relationship and factors like duration of disease, physical role limitations, and social stigma have a negative relationship with the quality of life of people with MS. The quality of life of people with MS is more influenced by mental and psychological factors than the physical limitations of these patients.
The effect of fatigue on postural control in individuals with multiple sclerosis: a systematic review
Authors: Sedaghati Parisa , Alghosi Mohammad , Hosseini Freshteh
Published: November 2023

Background

Fatigue is the most disabling symptom for individuals with multiple sclerosis (MS), which can significantly affect postural control (PC) by impairing the ability of the central nervous system to modulate sensory inputs and coordinate motor responses. This systematic review aimed to investigate the effect of fatigue on PC in individuals with MS..

Methods

This systematic review is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline and registered in PROSPERO with ID CRD42022376262. A systematic search was performed in the Web of Science, PubMed, Scopus, and Google Scholar until January 2023, and a manual search was performed using the reference lists of included studies. Two authors independently selected the studies, extracted data, and evaluated their methodological quality using the Downs and Black checklist. The process was later discussed with a third author..

Results

Five studies were included in this review, of which consistent evidence investigating a direct relationship between fatigue and PC in individuals with MS. All the studies reported negative effects on PC. Four studies employed walking tests as their primary protocol for inducing fatigue, while one study implemented a strength testing protocol for both legs, serving as a fatigue-inducing activity.

Conclusions

The evidence suggests that individuals with MS may experience PC deficits due to fatigue. However, the present body of literature exhibits limitations regarding its quality and methodology. Gender differences, balance, fatigue task, and muscle function are essential factors that need to be considered when investigating the relationship between fatigue and PC deficits in MS. Further high-quality research is necessary to comprehend the complex interplay between MS-related fatigue and PC deficits after physical activity.

Authors: Xia Huaqin , Yang Jiarui , Ding Yi , Wang Xinglin , Liao Yanfeng , Shi Yiwen , Dou Hongliang , Li Xuemin
Published: November 2023

Background

To explore the predictive value of Ellipsoid Zone (EZ) -related angle parameters for the outcome of primary macular hole surgery.

Methods

This was a retrospective study. Patients diagnosed with large macular hole (MH) (minimum diameter > 500 μm) between 2018 and 2021 were enrolled. All patients underwent 25-gauge pars plana vitrectomy, internal limiting membrane (ILM) peeling and air tamponade. Spectral-domain OCT (SD-OCT) and best corrected visual acuity (BCVA) were measured in preoperative and 2-week post-operative. Classic and angle related parameters were measured via ImageJ. Angle regularity (AR) were defined as the standard deviation of the angle parameters in vertical and horizontal direction.

Results

Seventy-six eyes were included for analysis; 24 eyes showed an unclosed macular hole at the 2-week postoperative and 52 eyes showed a closed hole. Preoperatively, MLD (P < 0.001), BD (P = 0.009) and diameter of EZ/ELM disruption (P = 0.002 and 0.025) in patients failed to close the hole after primary surgery were significantly larger than those succeeded. EZ-MH (P = 0.018), EZ-NFL (P = 0.006), EZ-GCL (P = 0.004), EZ-INL (P = 0.002), EZ-OPL (P = 0.009) and EZ-ONL (P = 0.011) angles were smaller in patients with unclosed hole. AR of the EZ-NFL (P = 0.009), EZ-GCL (P = 0.009), EZ-OPL (P = 0.023), EZ-ONL (P = 0.048) and Basal-NFL (P = 0.030) angles among the unclosed patients were significantly larger than those of the closed group. EZ-NFL (P = 0.015), EZ-GCL (P = 0.004), EZ-INL (P < 0.001), EZ-OPL (P < 0.001), EZ-ONL (P < 0.001), Basal (P = 0.023) and Basal-NFL (P < 0.001) angles of hole-unclosed patients enlarged significantly after the surgery.

Conclusions

Patients with large macular holes and an increased EZ-related angle and angle AR are more likely to experience unsuccessful outcomes following primary MH surgery. Therefore, EZ-related angles hold potential as valuable parameters for predicting the surgical outcome.
Bridging the gap: a qualitative study of providers' perceptions of a partnered crisis follow-up program for suicidal patients post-emergency department discharge
Authors: Soderlund Patricia D. , Cheung Erick H. , Cadiz Madonna P. , Siddiq Hafifa , Yerstein Maria , Lee Sae , Wells Kenneth , Heilemann MarySue V.
Published: November 2023

Background

Effective interventions are needed to address suicide risk following discharge from the hospital emergency department or inpatient setting. Studies that examine follow-up contact methods show promise, but little is known about how follow-up programs are implemented in the real world and who is benefitting. The purpose of this formative evaluation and analysis was to gain insight about the usefulness and value of a partnered suicide prevention follow-up program (academic medical center emergency department partnered with a regional suicide prevention center) from the standpoint of psychiatry resident physicians providing direct care and suicide prevention center crisis counselors making follow-up outreach telephone calls to patients.

Methods

A qualitative thematic analysis was conducted with focus group data from a convenience sample of psychiatry residents who performed consultations in the emergency department setting and counselors at the suicide prevention center crisis follow-up program. Focus group sessions, using semi-structured question guides, were completed at each participant group’s workplace. Grounded theory techniques were used to guide coding and analytic theme development.

Results

Analyses resulted in four overarching themes: valuing the program’s utility and benefit to patients, desiring to understand what happens from emergency department discharge to program follow-up, having uncertainty about which patients would benefit from the program, and brainstorming to improve the referral process. Psychiatry residents appreciated the option of an “active” referral service (one that attempts to actively engage a patient after discharge through outreach), while suicide prevention crisis counselors valued their ability to offer a free and immediate service that had potential for fostering meaningful relationships. Both participant groups desired a better understanding of their partner’s program operations, a uniform and smooth referral process, and awareness of who may or may not benefit from program services.

Conclusion

Results revealed the need for improved communication and implementation, such as expanded inter-agency contacts, consistent provider training, more documentation of the requirements and rules, a consistent message about program logistics for patients, and coordination between the program elements.

Recovery housing is an important resource for those in recovery from substance use disorders. Unfortunately, we know little about its relationship to key community health risk and protective factors, potentially limiting the role it could play as a broader health resource. Leveraging county-level data on recovery residences from the National Study of Treatment and Addiction Recovery Residences (NSTARR), this study used multilevel modeling to examine Community COVID Vulnerability Index (CCVI) scores as well as availability of COVID testing and vaccination sites in relation to recovery housing. CCVI composite scores were positively associated with recovery housing availability. Analyses using CCVI thematic sub-scores found that population density and number of churches were positively associated with recovery housing availability, while epidemiological factors and healthcare system factors were negatively associated with recovery housing availability. In counties with recovery housing, there also was a positive association between CCVI and both COVID testing and vaccination availability. Recovery residences tend to be located in areas of high COVID vulnerability, reflecting effective targeting in areas with higher population density, more housing risk factors, and other high-risk environments and signaling a key point of contact to address broader health issues among those in recovery from substance use disorders.

Background

The risk factors for mucus plug in children with adenovirus (ADV) pneumonia.

Methods and materials

A retrospective analysis was conducted of children diagnosed ADV pneumonia and underwent fiberoptic bronchoscopy admitted to the Xiamen Children's Hospital from September 2018 to September 2021.The patients were divided into a mucus plug group (39 cases) and a non-mucus plug group (53 cases). The children's data including sex, age, clinical presentation, laboratory test parameters, imaging and bronchoscopic data were collected. The risk factors for the development of airway mucus plug were analysed by multifactorial logistic regression.

Results

There were no statistically significant differences in sex, age, fever, hospitalization days, mixed infection, white blood cells (WBC) count, percentage of neutrophils (NE%), C-reactive protein(CRP), and D-dimer (all P > 0.05); Thermal range, procalcitonin (PCT), lactate dehydrogenase (LDH), Pleural effusion and associated decreased breath sounds was significantly higher in mucus plug group than in non-mucus plug group, and the differences were statistically significant (all P < 0.05); multifactorial logistic regression analysis showed that the duration of fever, PCT, and LDH were independent risk factors for the formation of mucus plugs. The critical values of ROC curves were pyroprocedure ≥ 6.5 d, PCT ≥ 0.705 ng/ml and LDH ≥ 478.5 U/L.

Conclusion

Duration of fever, PCT and LDH levels were the independent risk factors for the formation of an airway mucus plug in children with ADV pneumonia.

Published: November 2023

Background

N6-methyladenosine (m6A) RNA modification regulators play an important role in many human diseases, and its abnormal expression can lead to the occurrence and development of diseases. However, their significance in pulpitis remains largely unknown. Here, we sought to identify and validate the m6A RNA regulatory network in pulpitis.

Methods

Gene expression data for m6A regulators in human pulpitis and normal pulp tissues from public GEO databases were analyzed. Bioinformatics analysis including Gene ontology (GO) functional, and Kyoto encyclopedia of genes and genomes (KEGG) pathway analyses were performed by R package, and Cytoscape software was used to study the role of m6A miRNA-mRNA regulatory network in pulpitis. Quantitative real-time PCR (qRT-PCR) was performed to validate the expression of key m6A regulators in collected human pulpitis specimens.

Results

Differential genes between pulpitis and normal groups were found from the GEO database, and further analysis found that there were significant differences in the m6A modification-related genes ALKBH5, METTL14, METTL3, METTL16, RBM15B and YTHDF1. And their interaction relationships and hub genes were determined. The hub m6A regulator targets were enriched in immune cells differentiation, glutamatergic synapse, ephrin receptor binding and osteoclast differentiation in pulpitis. Validation by qRT-PCR showed that the expression of methylases METTL14 and METTL3 was decreased, thus these two genes may play a key role in pulpitis.

Conclusion

Our study identified and validated the m6A RNA regulatory network in pulpitis. These findings will provide valuable resource to guide the mechanistic and therapeutic analysis of the role of key m6A modulators in pulpitis.

Published: November 2023

Introduction

Chronic kidney disease could have a profound effect on the life of patients and family caregivers. The caregivers’ care burden increases as the disease progresses. Interventions reducing care burden should be investigated. Educational interventions could affect family caregivers’ care burden among hemodialysis patients. However, most studies and interventions have focused on caregivers. Therefore, this study aims to compare the effect of teaching Health-promoting behaviors on the care burden of family caregivers of hemodialysis patients.

Materials and methods

This trial was conducted using a pretest-posttest design and follow-up after one month. Hemodialysis patients and their family caregivers were selected using convenience sampling method. In total, 124 patient-caregiver pairs were divided into four groups of patient-centered education, caregiver-centered education, Patient and caregiver education and control by block randomization (15 blocks of 8 members and 1 block of 4 members) (n = 31 pairs per group). The intervention (teaching health-promoting behaviors) was performed in 8 sessions using the teach-back method, except for the control. The data were collected by patient and caregiver demographic forms and Novak and Guest care burden inventory as well as following the treatment regimen in three stages (before, immediately after and one month after the intervention). Demographic variables were compared among the four groups using ANOVA, Kruskal-Wallis and Chi-square test. The intragroup comparison of the main variables was made using the repeated measures ANOVA with modified LSD post hoc test. The intergroup comparison was made by one-way ANOVA with LSD post hoc test.

Results

Out of 124 caregivers participating in the study, 68 (54.8%) were female. Also, out of 124 patients participating in the study, 86 (69.4%) were male. The mean age of the caregivers and patients was 39.2 ± 11.31 and 54.23 ± 14.20 years old, respectively. There was a statistically significant difference in the mean total care burden scores of the pre-test and post-test between the four groups (p < 0.001). The total care burden decreased in patient-centered, caregiver-centered and Patient and caregiver education groups. However, this reduction in the caregiver-centered and Patient and caregiver education groups was significantly higher than the patient-centered education group (p < 0.001).

Conclusion

The results revealed teaching health-promoting behaviors reduced care burden. Moreover, caregiver-centered approach could reduce care burden more than patient-centered approach. Therefore, this could be used as a supportive method to improve the health of patients and caregivers.

Background

Low-pass genome sequencing (LP GS) has shown distinct advantages over traditional methods for the detection of mosaicism. However, no study has systematically evaluated the accuracy of LP GS in the detection of mosaic aneuploidies and copy number variants (CNVs) in prenatal diagnosis. Moreover, the influence of sequencing depth on mosaicism detection of LP GS has not been fully evaluated.

Methods

To evaluate the accuracy of LP GS in the detection of mosaic aneuploidies and mosaic CNVs, 27 samples with known aneuploidies and CNVs and 1 negative female sample were used to generate 6 simulated samples and 21 virtual samples, each sample contained 9 different mosaic levels. Mosaic levels were simulated by pooling reads or DNA from each positive sample and the negative sample according to a series of percentages (ranging from 3 to 40%). Then, the influence of sequencing depth on LP GS in the detection of mosaic aneuploidies and CNVs was evaluated by downsampling.

Results

To evaluate the accuracy of LP GS in the detection of mosaic aneuploidies and CNVs, a comparative analysis of mosaic levels was performed using 6 simulated samples and 21 virtual samples with 35 M million (M) uniquely aligned high-quality reads (UAHRs). For mosaic levels > 30%, the average difference (detected mosaic levels vs. theoretical mosaic levels) of 6 mosaic CNVs in simulated samples was 4.0%, and the average difference (detected mosaic levels vs. mosaic levels of Y chromosome) of 6 mosaic aneuploidies and 15 mosaic CNVs in virtual samples was 2.7%. Furthermore, LP GS had a higher detection rate and accuracy for the detection of mosaic aneuploidies and CNVs of larger sizes, especially mosaic aneuploidies. For depth evaluation, the results of LP GS in downsampling samples were compared with those of LP GS using 35 M UAHRs. The detection sensitivity of LP GS for 6 mosaic aneuploidies and 15 mosaic CNVs in virtual samples increased with UAHR. For mosaic levels > 30%, the total detection sensitivity reached a plateau at 30 M UAHRs. With 30 M UAHRs, the total detection sensitivity was 99.2% for virtual samples.

Conclusions

We demonstrated the accuracy of LP GS in mosaicism detection using simulated data and virtual samples, respectively. Thirty M UAHRs (single-end 35 bp) were optimal for LP GS in the detection of mosaic aneuploidies and most mosaic CNVs larger than 1.48 Mb (Megabases) with mosaic levels > 30%. These results could provide a reference for laboratories that perform clinical LP GS in the detection of mosaic aneuploidies and CNVs.

Published: November 2023

Background

Cancer-secreted exovesicles are important for cell-to-cell communication by altering cancer-related signalling pathways. Exovesicles-derived miRNAs (exomiRNAs)-target genes can be useful for diagnostic and prognostic purposes.

Methods

ExomiRNA from prostate cancer (PCa) cells (PC-3 and LNCaP) were quantified by qRT-PCR and compared to the healthy cell line RWPE-1 by using miRNome PCR 752 miRNAs Panel. MiRNet database was used to predict exomiRNA-target genes. ExomiRNA-target genes pathway functional enrichment was performed by using Reactome database and Enrichr platform. Protein–protein interaction analysis was carried out by using the STRING database. RNA target-gene sequencing data from The Cancer Genome Atlas Prostate Adenocarcinoma (TCGA-PRAD) database was screened out in 465 PCa patients for candidate gene expression in prostate tumour (PT) tissue and non-pathologic prostate (N-PP) tissue. Signature gene candidates were statistically analysed for diagnosis and prognosis usefulness.

Results

A total of 36 exomiRNAs were found downregulated when comparing PCa cells vs a healthy cell line; and when comparing PC-3 vs LNCaP, 14 miRNAs were found downregulated and 52 upregulated. Reactome pathway database revealed altered pathways and genes related to miRNA biosynthesis, miRNA-mediated gene silencing (TNRC6B and AGO1), and cell proliferation (CDK6), among others. Results showed that TNRC6B gene expression was up-regulated in PT tissue compared to N-PP (n = 52 paired samples) and could be useful for diagnostic purposes. Likewise, gene expression levels of CDK6, TNRC6B, and AGO1 were down-regulated in high-risk PT (n = 293) compared to low-risk PCa tissue counterparts (n = 172). When gene expression levels of CDK6, TNRC6B, and AGO1 were tested as a prognostic panel, the results showed that these improve the prognostic power of classical biomarkers.

Conclusion

ExomiRNAs-targets genes, TNRC6B, CDK6, and AGO1, showed a deregulated expression profile in PCa tissue and could be useful for PCa diagnosis and prognosis.
