Recreational use of nitrous oxide (N2O) has been associated with the development of severe nitrous oxide-induced neuropathy (N2On). Follow-up of these patients poses challenges, and their clinical progression remains largely unknown. The identification of prognostic factors is made difficult by the lack of standardized longitudinal assessments in most studies. The objective was to document the course of neuropathy through systematic follow-up assessments in N2On patients to identify prognostic factors for persistent disability after 6 months. We gathered demographic, clinical, biological, and electrophysiological data from N2On patients hospitalized in the Referral center in Marseille, both at baseline and during a standardized follow-up assessment at 6 months. We retrospectively included 26 N2On patients (mean age 22.6 ± 4.4). Significant improvements were observed in all main clinical scores including Rankin, ONLS, and MRC testing (p < .01). Electrophysiological studies (EDX) revealed a predominantly motor neuropathy with marked reduction in CMAP in the lower limbs at baseline, and no significant improvement in motor parameters (p = .543). Rankin score at 6 months correlated with the initial weekly N2O consumption (r = .43, p = .03) and the CMAP sum score in the lower limbs at the first EDX (r = -.47, p = .02). Patients with and without myelitis showed similar Rankin and ONLS score after 6 months. The clinical course generally improved favorably at 6 months with notable amelioration in the primary disability scores, sensory deficits, and ataxia. However, distal motor impairment associated with peripheral neuropathy persisted, with distal axonal loss emerging as the main prognostic factor for long-term disability in these young patients.
Recruiting special populations to smoking cessation trials is challenging and approaches beyond in-clinic recruitment may be beneficial. This secondary analysis of data from a smoking cessation RCT for individuals with a history of cervical cancer or cervical intraepithelial neoplasia (CIN) explored differences associated with in-clinic vs. online recruitment. Participants were recruited from clinics within a university-based NCI-designated cancer center (n=87) and online nationally via Facebook (n=115). Baseline measures included sociodemographics, smoking history, and cancer or CIN history. Study retention and smoking abstinence were assessed 12 months post-baseline. Group differences in baseline characteristics were evaluated. Retention and abstinence were evaluated while controlling for group differences and predictors. Participants recruited online (vs. in-clinic) had higher educational attainment (p=.01) and health literacy (p=.003). They were more likely to have CIN vs. cancer, to be further from the time of diagnosis, and to have completed active treatment (p values<.001). While controlling for these group differences and independent predictors, retention was higher among participants recruited online (log-likelihood χ2(1)=11.41, p<.001). There were no recruitment differences in self-reported (p=.90) or biochemically confirmed smoking abstinence (p=.18). Compared to individuals recruited in-person, individuals recruited online were more educated, had higher health literacy, and presented with a different clinical profile (i.e., more likely to have CIN vs. cancer and to have completed active treatment). There were few differences in participant characteristics between recruitment approaches, and no differences on any smoking-related variables. Online recruitment has the potential to improve enrollment of cancer survivors to smoking cessation trials. People with a history of CIN or cervical cancer recruited to a smoking cessation RCT online (vs. in-clinic) were more likely to have a diagnosis of CIN vs. cancer and were more educated and health literate. Participants recruited online were more likely to be retained in the study and there were no differences in smoking abstinence rates at 12-months. Incorporating online recruitment increased the reach of tobacco treatment efforts to a larger and more diverse sample. This could reduce the burden of tobacco-related disease, improve CIN and cancer treatment outcomes, and reduce secondary malignancies and morbidity among this underserved group.
Recruiting, retaining, and educating nursing students is essential to meet the growing need for nurses in rural communities. A nursing school enhanced its prelicensure education in rural and public health nursing, and interprofessional care by expanding experiential learning opportunities. To describe longitudinal community health-based rural immersion experiences for prelicensure nursing students. A prospective, correlational design evaluated students' knowledge and confidence in understanding rural characteristics, confidence in achieving public health nursing, and interprofessional education competencies. Fourteen prelicensure nursing students participated in rural maternal health immersion experiences and reported being more confident (21/27 items) than knowledgeable (18/27) in understanding rural characteristics. Over 85% reported competency in interprofessional interactions, and there was a significant difference in confidence in achieving public health nursing competencies between the beginning and end of the immersion. Using immersion experiences may be effective in enhancing students' knowledge, confidence, and competency in rural and public health, and interprofessional care.
Recruitment of a diverse participant pool to cancer clinical trials is an essential component of clinical research as it improves the generalizability of findings. Investigating and piloting novel recruitment strategies that take advantage of ubiquitous digital technologies has become an important component of facilitating broad recruitment and addressing inequities in clinical trial participation. Equitable and inclusive recruitment improves generalizability of clinical trial outcomes, benefiting patients, clinicians, and the research community. The increasing prevalence of online connectivity in the USA and use of the Internet as a resource for medical information provides an opportunity for digital recruitment strategies in cancer clinical trials. This study aims to measure the acceptability, preliminary estimates of efficacy, and feasibility of the Trial Library intervention, an Internet-based cancer clinical trial matching tool. This study will also examine the extent to which the Trial Library website, designed to address the linguistic and literacy needs of broader patient populations, influences patient-initiated conversations with physicians about clinical trial participation. This is a study protocol for a non-randomized, single-arm pilot study. This is a mixed methods study design that utilizes the statistical analysis of quantitative survey data and the qualitative analysis of interview data to assess the participant experience with the Trial Library intervention. This study will examine (1) acceptability as a measure of participant satisfaction with this intervention, (2) preliminary measure of efficacy as a measure of proportion of participants with documented clinical trial discussion in the electronic medical record, and (3) feasibility of the intervention as a measure of duration of clinical visit. The principles that informed the design of the Trial Library intervention aim to be generalizable to clinical trials across many disease contexts. From the ground up, this intervention is built to be inclusive of the linguistic, literacy, and technological needs of underrepresented patient populations. This study will collect essential preliminary data prior to a multi-site randomized clinical trial of the Trial Library intervention. This study has received institutional approval from the Committee of Human Subjects Research at the University of California, San Francisco.
Rectal cancer (RC) poses a significant global health challenge, causing substantial morbidity and mortality. This study aims to investigate the survival rates of RC patients and identify the factors that influence their survival. The study considers demographic characteristics, tumor features, and treatment received as the factors under consideration. A retrospective analysis was conducted on the medical records of 593 RC patients. Data were collected through a comprehensive review of medical records and conducting telephone interviews. Survival rates were estimated using the life table method, and subgroup comparisons were performed using the log-rank test. Cox regression analysis was utilized to assess the independent associations between RC survival time and various covariates. The study cohort comprised 593 RC patients, with a predominantly male representation. The mean age at diagnosis was 58.18 years, and the majority of patients (78.6 %) underwent surgical interventions. The median age at symptom onset and diagnosis were 58 and 59 years, respectively. Survival rates at 1st, 3rd, 5th, and 10th years were estimated to be 85 %, 59 %, 47 %, and 36 %, respectively. Statistical analysis revealed several significant prognostic factors, including age, education, symptoms, and cancer stage. In the multivariate Cox proportional-hazards analysis, advanced regional stage (HR = 1.54, 95 % CI, 1.13-2.08), presence of metastasis (HR = 3.73, 95 % CI, 2.49-5.58), and age over 70 (HR = 1.65) were associated with a higher risk of mortality. Given the alarming prognosis of RC observed in the study area and the significant delay between symptom onset and diagnosis, it is crucial to address this issue and potentially improve the survival rates of RC patients.
Rectal prolapse is still a relatively understudied medical condition, especially in women, whereas physical symptoms, depressive symptoms, and quality of life (QOL) in women with pelvic organ prolapse have been steadily studied. This study aimed to examine the interaction and main effects of physical and depressive symptoms on physical and mental QOL of women seeking care for rectal prolapse in Korea. Ninety-two women with rectal prolapse were recruited from a colorectal surgery clinic of a tertiary teaching hospital in Gwangju, Korea. Physical symptoms related to rectal prolapse (pelvic organ prolapse distress, POPD; colorectal-anal distress, CRAD; and urinary distress, UD), depression, and QOL were measured. The data were analyzed using descriptive statistics, Pearson correlation coefficient, and two-way analysis of variance. The interaction between POPD symptoms and depressive symptoms (F=4.51, p=.037) affected physical QOL. The interaction between POPD (F=9.66, p=.003) and CRAD symptoms (F=7.48, p=.008), respectively, and depressive symptoms affected mental QOL. Depressive symptoms had a significant main effect on the physical QOL in the CRAD (F=6.22, p=.014) and UD (F=6.01, p=.016) groups and on mental QOL in the UD group (F=24.54, p<.001). Physical and depressive symptoms should be considered together to improve the QOL in women with rectal prolapse. Nursing interventions and medical treatments to decrease rectal prolapse-related physical and depressive symptoms are required to improve QOL in women with symptomatic rectal prolapse.
Recurrence of low back pain (LBP) is common. If clinicians could identify an individual's risk of recurrence, this would enhance clinical decision-making and tailored patient care. To develop and validate a simple tool to predict the probability of a recurrence of LBP by 3- or 12-months following recovery. Data utilised for the prediction model development came from a prospective inception cohort study of participants (n = 250) recently recovered from LBP, who had sought care from chiropractic or physiotherapy services. The outcome measure was a recurrence of activity-limiting LBP. Candidate predictor variables (e.g., basic demographics, LBP history, levels of physical activity, etc) collected at baseline were considered for inclusion in a multivariable Cox model. The model's performance was tested in a separate validation dataset of participants (n = 261) involved in a randomised controlled trial investigating exercise for the prevention of LBP recurrences. The final model included the number of previous episodes, total sitting time, and level of education. In the development sample, discrimination was acceptable (Harrell's C-statistic = 0.61, 95% CI, 0.59-0.62), but in the validation sample, discrimination was poor (0.56, 95% CI, 0.54-0.58). Calibration of the model in the validation dataset was acceptable at 3 months but was less precise at 12 months. The developed prediction model, which included number of previous episodes, total sitting time, and level of education, did not perform adequately in the validation sample to recommend its use in clinical practice. Predicting recurrence of LBP in clinical practice remains challenging.
Recurrent depressive episodes are preceded by changing mean levels of repeatedly assessed emotions (e.g., feeling restless), which can be detected in real time using statistical process control (SPC). This study investigated whether monitoring changes in the standard deviation (SD) of emotions and negative thinking improves the early detection of recurrent depression. Formerly depressed adults (N = 41) monitored their emotions five times a day for 4 consecutive months. During the study, 22 individuals experienced recurrent depression. We used SPC to detect warning signs (i.e., changing means and SDs) of four emotions (positive and negative affect with high or low arousal) and negative thinking. SD-based warning signs only preceded 23%-36% of recurrences, but almost never reflected a false alarm (0%-16%). Correspondingly, SD-based warnings had a high specificity (at the cost of sensitivity), while mean-based warnings had a higher sensitivity (but lower specificity). There was little overlap in mean- and SD-based warning signs. For the majority of emotions, monitoring for high SDs alongside monitoring changes in mean levels improved the detection of depression (p < .015) compared to when only monitoring for changing mean levels. Warning signs for depression manifest not only in changing mean levels of emotions and cognitions but also in increasing SDs. These warnings could eventually be used to detect not just who is at increased risk for depression but also when risk is rising. Further research is needed to evaluate the clinical utility of depression SPC. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
Recurrent implantation failure (RIF) is a challenging clinical situation and various strategies have been tried to improve the pregnancy rate in RIF. Platelet-rich plasma (PRP), which is obtained from the autologous blood samples of a person and is multiple times richer in platelets and other growth factors helps improve endometrial receptivity. This study has been conducted to summarise the evidence and quality of evidence available so far regarding the role of PRP in cases of unexplained RIF. An electronic database search for randomised clinical trials comparing PRP against routine care in women with unexplained RIF was performed on PubMed, EMBASE, SCOPUS and Cochrane Central. Two independent reviewers conducted a literature search and retrieved data using the predefined eligibility criteria. Bias assessment was done using the Cochrane Collaboration Network Risk of Bias Tool version 2. The quality of evidence was determined and a summary of the findings table was prepared for individual outcomes using GRADEpro software. We identified 1146 records, and after removing duplicates, 531 records were screened. Out of these, 22 studies reached full-text screening and nine studies were included in the final review. We are uncertain about the effect of PRP due to the very low quality of evidence and we have little confidence that the administration of PRP had any significant effect on improving the live birth rate in women with RIF (odds ratio [OR]: 7.32, 95% confidence interval [CI]: 4.54-11.81, I2 = 40%). Similarly, the quality of evidence was low for the clinical pregnancy rate, so we are uncertain if the administration of PRP had any significant effect on the clinical pregnancy rate (OR: 3.20, 95% CI: 2.38-4.28, I2 = 0%). The current review suggests that there may be some beneficial effects of PRP in women with RIF, but the quality of evidence is very low and we are uncertain of the benefit and have little confidence in these findings. Limitations are the small sample size of most studies, a short follow-up period, non-uniformity in the definition of outcomes and very low quality of evidence. The protocol was registered on PROSPERO (CRD42021292209).
Recurrent neural networks (RNN) are ubiquitously used in neuroscience to capture both neural dynamics and behaviors of living systems. However, when it comes to complex cognitive tasks, traditional methods for training RNNs can fall short in capturing crucial aspects of animal behavior. To address this challenge, we take inspiration from a commonly used (though rarely appreciated) approach from the experimental neuroscientist's toolkit: behavioral shaping. Our solution leverages task compositionality and models the animal's relevant learning experiences prior to the task. Taking as target a temporal wagering task previously studied in rats, we designed a pretraining curriculum of simpler cognitive tasks that are prerequisites for performing it well. These pretraining tasks are not just simplified versions of the temporal wagering task, but reflect relevant sub-computations. We show that this approach is required for RNNs to adopt similar strategies as rats, including long-timescale inference of latent states, which conventional pretraining approaches fail to capture. Mechanistically, our pretraining supports the development of key dynamical systems features needed for implementing both inference and value-based decision making. Overall, our approach addresses a gap in neural network model training by incorporating inductive biases of animals, which is important when modeling complex behaviors that rely on computational abilities acquired from past experiences.
Red blood cell antigens are numerous in structural and functional diversity; some are proteins while others are carbohydrates. The international society of blood transfusion currently recognized 43 blood group systems containing 349 red cell antigens. It also acknowledged 9 blood group systems (ABO, Rhesus, Kell, Duffy, Kidd, MNS, P, Lewis, and Lutheran) that are clinically significant and associated with hemolytic transfusion reactions as well as hemolytic disease of fetuses and newborns. The objective of this study was to assess the distribution of minor blood group antigens and their phenotype among voluntary blood donors in Ethiopian blood and tissue bank service in Addis Ababa. A cross-sectional study was conducted from January to March 2022 among 260 volunteer blood donors to determine minor blood group antigens and their phenotype at EBTBS, Addis Ababa, Ethiopia. Tests were performed using Galileo Neo Immucor, which is fully automated Immunohematology analyzer. A total of 260 blood donors were screened of which 153 (59%) were males. The antigen frequencies of minor blood group systems were: Fy(a), Fy(b), Jk(a), Jk(b), k, S, s were 33.5%, 43.5%, 97.7%), 40.4%), 100%, 45%, 90%, respectively. Regarding phenotype distribution, the most common phenotypes were: Duffy Fy (a-b+) 36.9%, MNS S-s+ 55% and Kidd Jk (a+b-) 59.6%. This study highlights the frequencies of Fy(a), Fy(b), Jk(a), Jk(b), k, S and s blood group antigens and their phenotypes in volunteer blood donors at EBTBS, Addis Ababa. For the management of alloimmunization cases in transfused patients, knowledge of these minor blood group antigens is relevant.
Red eye is a common symptom in patients visiting the ophthalmology outpatient department (OPD). However, not all with red eye are due to infection and some can be threatening to visual loss. This study aimed to explore the knowledge, attitude, and practice (KAP) among the general public regarding red eye attending a tertiary care hospital, Tamil Nadu. A cross-sectional study was conducted after approval by the institutional ethics review board among 500 patients >18 years attending general OPD excluding ophthalmology in tertiary hospital and research institute, Tamil Nadu, from January 2022 to April 2022. After informed consent, a semi-structured questionnaire with details of KAP on red eye was used and analyzed with descriptive statistics and Chi-square test using SPSS version 16. Among the 500 participants, one-third were >60 years, 58%-females. Only 15.6% had awareness on red eye, 12.6% were aware of serious side effects while <10% knew the complication of red eye such as visual loss can follow if left untreated. Among those aware, 63% reported infection as the most common cause, followed by injury and allergy. Source of awareness was from past experience in the majority of the patients, followed by mass media and doctors. Only 12.4% had a positive attitude while 14.2% had good practice of seeking medical attention. Harmful practices such as instilling breast milk and instilling over-counter drops were highly prevalent. The major determinants of awareness were younger age, literacy, and health education given by health personnel (P < 0.05). Awareness about red eye, attitude, and practice among the general population in rural settings in Tamil Nadu are still poor. The need of the hour is for health education on red eye and management to prevent morbidity and loss of vision in the community at all levels of health care.
Redesigning undergraduate biology courses to integrate quantitative reasoning and skill development is critical to prepare students for careers in modern medicine and scientific research. In this paper, we report on the development, implementation, and assessment of stand-alone modules that integrate quantitative reasoning into introductory biology courses. Modules are designed to improve skills in quantitative numeracy, interpreting data sets using visual tools, and making inferences about biological phenomena using mathematical/statistical models. We also examine demographic/background data that predict student improvement in these skills through exposure to these modules. We carried out pre/postassessment tests across four semesters and used student interviews in one semester to examine how students at different levels approached quantitative problems. We found that students improved in all skills in most semesters, although there was variation in the degree of improvement among skills from semester to semester. One demographic variable, transfer status, stood out as a major predictor of the degree to which students improved (transfer students achieved much lower gains every semester, despite the fact that pretest scores in each focus area were similar between transfer and nontransfer students). We propose that increased exposure to quantitative skill development in biology courses is effective at building competency in quantitative reasoning.
