High-intensity interval training is feasible, credible and clinically effective in the early subacute stroke stage in the low-income country of Benin

ABSTRACT High-intensity interval training (HIIT) has been shown to benefit stroke patients when implemented three months post-stroke. This study examined HIIT’s feasibility and clinical effectiveness in the early post-stroke stage in Benin. This was a prospective interventional study comprising an HIIT programme executed on a recumbent bike, three times/week, 20–30 min/session for 6 weeks, added to a conventional physiotherapy. The primary outcomes were feasibility, credibility and expectancy assessed with credibility and expectancy questionnaire. A maximal exercise test, 6-min walking test (6MWT), 10-m walking test (10mWT), Berg balance scale (BBS) and five repetitions sit-to-stand test (5 R-STS) were performed before and after the training programme. Ten outpatients, with a median age [P25-P75]: 63.5[56.7–71.2] years; time since stroke: 15.0[9.7–21.0] days, started and completed all training sessions without serious adverse events. High scores were observed on the Credibility subscale at admission (27.0[25.7–27.0]), which remained so after intervention (26.5[25.7–27.0]). Expectancy subscale scores were high at admission (25.5[24.0–27.0]) and post-training (25.5[24.5–27.0]). Peak workload (p < 0.001), BBS (p < 0.001), 6MWT (p < 0.001), 10mWT (p < 0.001) and 5 R-STS (p = 0.004) were all improved. HIIT is feasible and safe in the early subacute post-stroke stage and is perceived by patients as highly credible, meeting their expectations of recovery.

Psycho-social Stressors Experienced by Young war Refugees in Developed Countries: A Scoping Review.

Refugees escaping political unrest and war are an especially vulnerable group. Arrival in high-income countries (HICs) is associated with a 'new type of war', as war refugees experience elevated rates of psycho-social and daily stressors. The purpose of this scoping review is to examine literature on psycho-social stressors amongst young war refugees in HICs and impact of stressors on intergenerational transmission of trauma within parent-child dyads. The secondary objectives are to identify the pre-migration versus post-migration stressors and provide a basis to inform future research projects that aim to lessen the burden of stress and inform evidence-based improvements in this population. Preferred Reporting Items for Systematic Reviews and Meta-Analyses Scoping Review Extension (PRISMA-ScR) guided the reporting of this review that was performed using a prescribed scoping review method. Extracted from five databases, 23 manuscripts published in 2010 or later met the inclusion criteria. Three themes emerged: pre-migration stressors, migration journey stressors and uncertainty, and post-migration stressors. While post-migration environments can mitigate the health and well-being of war refugees, socio-cultural barriers that refugees often experience at the host country prevent or worsen their psycho-social recovery. To assist the success of war refugees in HICs, therapeutic interventions must follow an intersectional approach and there needs to be a wider application of trauma informed models of care. Findings of this review may help inform future intervention studies aiming to improve the psycho-social health of this population.

Combined healthy lifestyles and risk of depressive symptoms: A baseline survey in China

BackgroundLittle evidence exists about whether a combination of healthy lifestyle factors is associated with a lower risk of depressive symptoms among Chinese population. We aimed to investigate the association between combined healthy lifestyle factors and risk of depressive symptoms. MethodsWe conducted a baseline survey from July 2021 to December 2023, including 53,642 Chinese adults from general population. A healthy lifestyle score was constructed based on six lifestyle factors (physical activity, smoking status, alcohol consumption, diet, sleep duration, and body mass index). Logistic regression models were used to estimate odds ratios (ORs) and 95 % confidence intervals (CIs) adjusted for confounding variables. ResultsEach additional healthy lifestyle score was associated with a 20 % lower risk of having depressive symptoms (OR (95 % CI): 0.80 (0.78–0.81)). Compared with individuals with ≤2 healthy lifestyle factors, individuals with all the six healthy lifestyle factors had a 58 % reduced risk of having depressive symptoms (0.42 (0.37–0.47)). After stratification by gender, education and urbanization, the significant inverse association with healthy lifestyle score was stronger in women, individuals with high education, and urban residents. Besides, the significant negative association between healthy lifestyle score and depressive symptoms remained for different severity of depressive symptoms. LimitationsGiven the cross-sectional nature of data, we cannot make causal inferences. ConclusionsOur study indicated that adherence to healthy lifestyle factors was associated with a reduced risk of having depressive symptoms among Chinese adults. The observed associations were modified by gender, education and urbanization. These findings warrant further verification in interventional studies.

Door-to-antibiotic time and mortality in patients with sepsis: Systematic review and meta-analysis

ObjectivesTo evaluate whether the timing of initial antibiotic administration in patients with sepsis in hospital affects mortality. MethodsThis systematic review and meta-analysis included studies from inception up to 19 May 2022. Interventional and observational studies including adult human patients with suspected or confirmed sepsis and reported time of antibiotic administration with mortality were included. Data were extracted by two independent reviewers. Summary estimates were calculated by using random-effects model. The primary outcome was mortality. ResultsWe included 42 studies comprising 190,896 patients with sepsis. Pooled data showed that the OR for patient mortality who received antibiotics ≤1 hr was 0.83 (95 %CI: 0.67 to 1.04) when compared with patients who received antibiotics >1hr. Significant reductions in the risk of death in patients with earlier antibiotic administration were observed in patients ≤3 hrs versus >3 hrs (OR: 0.80, 95 %CI: 0.68 to 0.94) and ≤6 hrs vs 6 hrs (OR: 0.57, 95 %CI: 0.39 to 0.82). ConclusionsOur findings show an improvement in mortality in sepsis patients with early administration of antibiotics at <3 and <6 hrs. Thus, these results suggest that antibiotics should be administered within 3 hrs of sepsis recognition or ED arrival regardless of the presence or absence of shock.

Developing Disability Advocates Through Deliberate Interprofessional Conversations Regarding Quality of Life After Stroke

ObjectiveStroke can result in significant mental and physical impairment. Training health care professionals on effective strategies for mitigating stroke-related quality-of-life issues is crucial in facilitating comprehensive stroke management. This study aimed to evaluate the impact of an interprofessional education (IPE) experience on students’ attitudes regarding poststroke disability. MethodsIn this pre-post interventional study, pharmacy and medical students received an electronic patient chart and a store-and-forward video depicting physical and cognitive impairment in a patient with stroke. Students were instructed to discuss the acute management and postdischarge needs of the patient from an advocacy perspective. After the IPE experience, students completed the Student Perceptions of Interprofessional Clinical Education-Revised, version 2 and an unvalidated disability attitudes survey. The surveys were analyzed using a paired t test. In addition, students reflected on the prompt, “What are some things you had NOT considered prior to this IPE?” ResultsA total of 708 students completed the surveys. After IPE, there was a significant improvement in all domains of the Student Perceptions of Interprofessional Clinical Education-Revised, version 2. On the disability survey, there was significant improvement on all statements, including “rate your comfort with…”: “discussing the expected disabilities associated with new-onset stroke” and “discussing strategies for improving the quality of life of a patient who has long-term disabilities.” On the self-reflections, 31.7% (n = 211) had not considered the need for poststroke care services before this IPE. ConclusionThis IPE experience was instrumental in improving student perspectives regarding poststroke disability.

The most optimal school recruitment strategies for school-based obesity prevention and health promotion research in the United States: A systematic review with Delphi study.

This systematic review with the Delphi study aimed to identify effective and resource-efficient (optimal) strategies for recruiting schools into health promotion interventions in the United States. A literature search was conducted in PubMed, Cochrane Library, and CINAHL (EBSCO). A total of 116 interventions reported in 160 articles were included. Most school-based interventions did not report data regarding school recruitment duration (81%), target school size (63%), and school recruitment strategies (78%). Further, no details were provided regarding the reasons for declining to participate despite being eligible. For the Delphi, responses from 23 researchers in school-based clinical trials were collected. A qualitative descriptive approach was used for coding responses and collapsed into higher-order categories based on school recruitment strategies. Delphi participants reported that (1) creating new or leveraging pre-existing partnerships, (2) intervention champion, (3) minimal school disruptions, (4) working with open mind/flexibility, and (5) transparent communication are the most optimal school recruitment strategies. Staff time and travel were the most frequently reported costs for implementing those strategies. The overall trend in school-based obesity prevention intervention studies illustrates the importance of a better understanding school recruitment. Improved reporting can allow researchers to budget their time and resources better and provide greater confidence in reaching their target school size.

Vitamin D and Muscle Status in Inflammatory and Autoimmune Rheumatic Diseases: An Update.

Background and Objectives: Vitamin D is a secosteroid hormone essential for calcium homeostasis and skeletal health, but established evidence highlights its significant roles also in muscle health and in the modulation of immune response. This review aims to explore the impact of impaired vitamin D status on outcomes of muscle function and involvement in inflammatory and autoimmune rheumatic diseases damaging the skeletal muscle efficiency both with direct immune-mediated mechanisms and indirect processes such as sarcopenia. Methods: A comprehensive literature search was conducted on PubMed and Medline using Medical Subject Headings (MeSH) terms: "vitamin D, muscle, rheumatic diseases." Additionally, conference abstracts from The European Alliance of Associations for Rheumatology (EULAR) and the American College of Rheumatology (ACR) (2020-2023) were reviewed, and reference lists of included papers were scanned. The review emphasizes the evidence published in the last five years, while also incorporating significant studies from earlier years, structured by the extent of evidence linking vitamin D to muscle health in the most commonly inflammatory and autoimmune rheumatic diseases encountered in clinical practice. Results: Observational studies indicate a high prevalence of vitamin D serum deficiency (mean serum concentrations < 10 ng/mL) or insufficiency (<30 ng/mL) in patients with idiopathic inflammatory myopathies (IIMs) and polymyalgia rheumatica, as well as other autoimmune connective tissue diseases such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and systemic sclerosis (SSc). Of note, vitamin D insufficiency may be associated with reduced muscle strength (2 studies on RA, 2 in SLE and 1 in SSc), increased pain (1 study on SLE), fatigue (2 studies on SLE), and higher disease activity (3 studies on IIMs and 1 on SLE) although there is much heterogeneity in the quality of evidence and different associations for the different investigated diseases. Therefore, linked to the multilevel biological intervention exerted by vitamin D, several translational and clinical studies suggest that active metabolites of this secosteroid hormone, play a role both in reducing inflammation, but also in enhancing muscle regeneration, intra-cellular metabolism and mitochondrial function, although interventional studies are limited. Conclusions: Altered serum vitamin D status is commonly observed in inflammatory and autoimmune rheumatic diseases and seems to be associated with adverse muscle health outcomes. While maintaining adequate serum vitamin D concentrations may confer muscle-protective effects, further research is needed to confirm these findings and establish optimal supplementation strategies to obtain a safe and efficient serum threshold.

Chrononutrition and Cardiometabolic Health: An Overview of Epidemiological Evidence and Key Future Research Directions.

Chrononutrition is a rapidly evolving field of nutritional epidemiology that addresses the complex relationship between temporal eating patterns, circadian rhythms, and metabolic health, but most prior research has focused on the cardiometabolic consequences of time-restricted feeding and intermittent fasting. The purpose of this topical review is to summarize epidemiological evidence from observational and intervention studies regarding the role of chrononutrition metrics related to eating timing and regularity in cardiometabolic health preservation and cardiovascular disease prevention. Observational studies are limited due to the lack of time-stamped diet data in most population-based studies. Findings from cohort studies generally indicate that breakfast skipping or the later timing of the first eating occasion, a later lunch and dinner, and a greater proportion of caloric intake consumed in the evening are associated with adverse cardiometabolic outcomes, including higher risk for coronary heart disease, hypertension, type 2 diabetes, obesity, dyslipidemia, and systemic inflammation. Randomized controlled trials are also limited, as most in the field of chrononutrition focus on the cardiometabolic consequences of time-restricted feeding. Overall, interventions that shift eating timing patterns to earlier in the day and that restrict evening caloric intake tend to have protective effects on cardiometabolic health, but small sample sizes and short follow-up are notable limitations. Innovation in dietary assessment approaches, to develop low-cost validated tools with acceptable participant burden that reliably capture chrononutrition metrics, is needed for advancing observational evidence. Culturally responsive pragmatic intervention studies with sufficiently large and representative samples are needed to understand the impact of fixed and earlier eating timing schedules on cardiometabolic health. Additional research is warranted to understand the modifiable determinants of temporal eating patterns, to investigate the role of chrononutrition in the context of other dimensions of diet (quantity, quality, and food and nutrition security) in achieving cardiometabolic health equity, and to elucidate underlying physiological mechanisms.

Understanding the Landscape of Multi-Cancer Detection Tests: The Current Data and Clinical Considerations.

Multi-cancer detection (MCD) tests are blood-based assays that screen for multiple cancers concurrently and offer a promising approach to improve early cancer detection and screening uptake. To date, there have been two prospective interventional studies evaluating MCD tests as a screening tool in human subjects. No MCD tests are currently approved by the FDA, but there is one commercially available MCD test. Ongoing trials continue to assess the efficacy, safety, and cost implications of MCD tests. In this review, we discuss the performance of CancerSEEK and Galleri, two leading MCD platforms, and discuss the clinical consideration for the broader application of this new technology.

A systematic review and meta-analysis on TPACK-based interventions from a perspective of knowledge integration

Designing effective interventions that foster (pre-service) teachers' knowledge to teach with technologies is paramount in education research. Researchers have prominently relied on the TPACK-model as theoretical foundation to design such interventions. However, a myriad of distinct TPACK-based interventions emerged, which likely targeted the different knowledge components of TPACK to varying extents. Given this diversity and the lack of performance-based measures to estimate competence growth, little is known about the effectiveness of respective interventions. In the present synthesis study, we therefore sought to systemize TPACK-based interventions regarding targeted knowledge domains across various contexts. Accordingly, we scrutinized which of the TPACK-components were explicitly targeted in TPACK-based interventions within the framework of a systematic review. Further, we conducted a subsequent meta-analysis based on studies applying performance-based measures to investigate whether the targeted knowledge domains affected the effectiveness of interventions. Based on a set of N = 163 primary intervention studies and one theoretical contribution, our analyses suggest that Technological Knowledge was the most prominent targeted TPACK-component. Interestingly, in more than 20% of the interventions, specific training on Technological Pedagogical Content Knowledge (i.e., TPCK) was absent although TPCK is considered crucial for successful technology integration. Results further revealed that researchers do not seem to have adapted the design of interventions on instructional contexts (such as the expertise level of the target audience). The results of the subsequent meta-analysis (N = 8) further provided no clear evidence that targeted TPACK-components affected the effectiveness of interventions.

Sleep interventions in pediatric oncology: A systematic review of the evidence.

Sleep concerns are common during pediatric cancer treatment and can last into survivorship. The current systematic review sought to identify intervention studies that addressed sleep as a primary or secondary outcome during pediatric cancer treatment up to 5years after completing treatment. Quality assessment was rated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. The review identified 16 studies with a total of 943 participants that tested a wide range of interventions including psycho-educational, stress management techniques, medications, and physical activity. Most studies included tested interventions in small samples. None of the included studies had a high risk of bias for all domains, but all included studies had a high risk of bias for at least two risk domains. Several feasible pilot studies were identified that warrant further research to test efficacy. Implications for future research and clinical practice to manage sleep concerns are discussed.

Endometriotic tissue fragments are viable after cryopreservation in an ex vivo tissue model recapitulating the fibrotic microenvironment.

Is it possible to establish an ex vivo endometriosis model using cryopreserved endometriotic tissue fragments? Cryopreserved endometriotic tissue fragments remain viable after thawing and during at least 3days of culture and can therefore be used to establish an ex vivo endometriosis model to efficiently test potential therapeutic agents. Endometriosis is the most prevalent benign gynecologic disease with an enormous societal burden; however, curative therapies are still lacking. To efficiently test potential new therapies, an ex vivo model based on previously cryopreserved endometriotic tissue that recapitulates the different endometriosis subtypes and their microenvironment is highly desirable. Endometriotic tissue fragments of three different subtypes were obtained from 28 patients by surgical resection. After cryopreservation and thawing, viability and metabolic activity of these tissue fragments were assessed. Viability was compared with fresh fragments from 11 patients directly after surgical removal. Experimental intervention studies were performed in cryopreserved and thawed tissue fragments from two patients to confirm the usability of these tissues for ex vivo intervention studies. Endometriotic tissue fragments (n = 45) were cryopreserved according to three different protocols. After thawing, fragments were cultured for 24 h. A resazurin-based assay was performed to assess the metabolic activity of the tissue fragments. In addition, cell type-specific viability was analyzed by VivaFix, Hoechst 33342, and α-smooth muscle actin immunofluorescence staining and confocal microscopy. The presence of endometriosis was histologically confirmed based on hematoxylin-eosin staining. Cryopreserved and thawed tissue fragments were treated for 72 h with pirfenidone or metformin and COL1A1 and CEMIP gene expressions were assessed using RT-PCR and RT-qPCR, either in the whole tissue fragments or in myofibroblasts isolated by laser capture microdissection. Metabolic activity of endometriotic tissue fragments obtained from peritoneal (PER), ovarian (OMA), and deep (DE) endometriotic lesions was well preserved after cryopreservation in a dimethyl sulfoxide-based medium and was comparable with fresh tissue fragments. Relative metabolic activity compared to fresh tissue was 70% (CI: 92-47%) in PER, 43% (CI: 53-15%) in OMA and 94% (CI: 186-3%) in DE lesions. In fragments from PE lesions 92% (CI: 87-96%), from OMA lesions 95% (CI: 91-98%), and from DE lesions 88% (CI: 78-98%) of cells were viable after cryopreservation and thawing followed by a 24-h culture period. Differences in gene expression of fibrotic markers COL1A1 and CEMIP after 72-h treatment with pirfenidone or metformin could be detected in whole tissue fragments and in isolated myofibroblasts, indicating that cryopreserved and thawed endometriotic tissue fragments are suitable for testing anti-fibrotic interventions. N/A. Viability and metabolic activity of the endometriotic tissue fragments may have been partially compromised by damage sustained during the surgical procedure, contributing to inter-sample variance. The storage of viable endometriotic tissue fragments for later usage in an ex vivo model creates the possibility to efficiently test potential new therapeutic strategies and facilitates the exchange of viable endometriotic tissue between different research laboratories. This study was not financially supported by external funding. The authors declare no competing interest. N/A.

Serum autotaxin level: a promising diagnostic biomarker in differentiating Graves' disease and thyroiditis.

Recent studies have suggested that serum autotaxin (ATX) may be a promising diagnostic biomarker in differentiating between Graves' disease (GD) and thyroiditis, as well as serving as a monitoring biomarker for GD. This study will evaluate the use of serum ATX as a diagnostic biomarker in these conditions. In this prospective interventional study, blood samples were collected from the patients who met both inclusion and exclusion criteria, and serum ATX levels were measured by using the MyBioSource human Autotaxin ELISA kit. A total of 32 patients were enrolled, of which 18.8% were newly diagnosed with GD, 21.9% were thyroiditis, and 59.3% were on treatment for GD. Serum autotaxin antigen was significantly higher in GD patients than in thyroiditis (603.3217±444.24 v/s 214.74±55.91, P = <.005). Serum ATX measurement successfully discriminated GD patients from thyroiditis (AUC = 0.952, 95%CI: 0.00-1.00) with an optimal cutoff value of ≥257.20ng/L (sensitivity = 100 and specificity = 81.71). Monitoring the efficacy of serum ATX was analyzed and showed a significant difference. The serum ATX was higher in subjects with GD as compared to thyroiditis, and ATX levels were found to be decreased during the treatment period. In conclusion, serum ATX can be used as a diagnostic and monitoring biomarker in GD.

Effects of Melatonin Supplementation on Clinical Symptoms and Paraclinical Outcomes in Women Diagnosed With Fibrocystic Breast Disease: An Interventional Study

Fibrocystic breast disease is the most common benign breast disease in women, and it is necessary to investigate the most effective treatment method to reduce its symptoms. Therefore, the study was conducted to investigate the effect of melatonin supplementation on clinical symptoms and paraclinical outcomes in women diagnosed with fibrocystic breast disease. Investigating the Effects of melatonin supplementation on clinical symptoms and paraclinical outcomes in women diagnosed with fibrocystic breast disease. The present study is a controlled intervention-placebo treatment conducted on women suffering from fibrocystic breast disease aged 18-40. This interventional study was conducted on 66 patients (33 in the intervention group and 33 in the control group). Melatonin supplement of 3 mg was administered to the intervention group and a placebo to the control group for 12 weeks. Patient information, symptoms, and paraclinical outcomes were recorded at the beginning of the study before the intervention and 12 weeks after the intervention. After collecting the data, we analyzed it using SPSS version 16 software and appropriate statistical tests. The findings of this study showed that melatonin administration in patients with fibrocystic breast disease reduced anxiety, depression, improved sleep quality, increased TAC (Total Antioxidant Capacity), and decreased MDA (Malondialdehyde). However, both study groups did not have statistically significant differences in the average pain and hs-CRP before and after the intervention. According to the findings of the study and the identification of the positive effect of melatonin on laboratory indicators and symptoms in patients with fibrocystic breast disease, it is recommended to prescribe melatonin in addition to standard treatment to witness a better and faster recovery, and in this way, the quality of life of patients can be increased.

Physical function measures in ICU survivors, where to now? A scoping review

Background. Growing evidence is describing the long-term morbidity experienced by critical illness survivors, a major contributing factor being impaired physical function. Consensus is yet to be reached on which physical function measures should be included in this population. This review aimed to describe physical functioning measurement instruments used in longitudinal studies of critical illness survivors, based on the International Classification of Function (ICF). Methods. An electronic database search of EbscoHost, Web of Science and Scopus was conducted from inception to November 2023. Two reviewers independently applied the inclusion and exclusion criteria to titles, abstracts and full text-studies. Extracted data included year of publication; country; participant age; follow-up timeframes and physical measurement instruments used. Instruments were classified according to ICF domains. Results. Eighty studies published between 1995 and November 2023 were included. Forty-four different outcome measures were identified. Most studies (68) included multiple followed-up points and were completed within a year, and few studies (12) follow-up beyond a year. Based on the ICF, 11 (25%) instruments measured impairments and 33 (75%) activity limitations. Muscle power functions were the most frequently measured impairment (65%), utilising manual muscle testing (37.3%). The six-minute walk test (6MWT) was the most frequently used instrument in the activity/participation domain (31.6%). Only one instrument addressed all five the physical activity/participation domains, while the majority focused on mobility domain. Conclusions. Multiple tools are used to report on physical deficits experienced by ICU survivors, either measuring impairments or activity/ participation limitations. Most studies report on physical function within the first year of survival. The heterogeneity and inconsistency over time of instruments used prevents synthesis of data to determine intervention efficacy. The validity, predictive value and sensitivity of the reported measures within ICU survivors needs to be established, only then can intervention studies be designed to measure effectiveness.

The effectiveness of supportive management programs in caregivers of patients with heart failure: a systemartic review

Abstract Introduction Supportive management programs involving caregivers of heart failure (HF) patients may be beneficial not only for the patient, but also for the caregiver. This study aims to investigate the effectiveness of supportive management programs for caregivers in terms of quality of life (QoL), depressive and/or anxiety symptoms and caregivers’ burden. Methods A systematic review was conducted in order to identify interventional studies delivering supportive management programs to dyads and evaluating the effectiveness for caregivers in terms of their QoL, depressive symptoms and burden. A systematic search in PubMed, CINAHL, and the Cochrane Library was performed. Inclusion and exclusion criteria and the Preferred Reporting Items (PRISMA) statement checklist were used. Fourteen randomized (RCT’s) and interventional studies were included. Results Fourteen articles were included in the review from a pool of thirty-five papers. A large heterogeneity was observed among the studies regarding several aspects; the intervention as such (e.g psychological support, cognitive behavioral therapy), the duration of the follow- up period and the method that the intervention was delivered (e.g telephone conducts, home visits). Another striking feature was the variety of outcomes that were studied. The most common outcomes were: anxiety and depressive symptoms, burden and impaired quality of life. Conclusions Supportive care management programs are beneficial for both, the patients and the caregivers. It provides the supporting environment for the best possible results and outcomes and most importantly quality of life of the patients and the caregivers.

Evaluation of Success and Complications Scores for Chronic Total Occlusion Percutaneous Coronary Interventions: Insights from the Latin American Registry

Chronic total occlusion (CTO) percutaneous coronary intervention is a complex procedure and is associated with considerable risk of complications. Several success and complication scores have been developed; however, data regarding their external validation in other populations such as Latin America are scarce. This study aimed to evaluate the accuracy of the main predictors of success and complications in a broad cohort of procedures in the Latin American (LATAM) CTO registry. From April 2008 to December 2023, 3,706 consecutive procedures listed in the LATAM CTO registry were screened. Of these, 2,835 procedures had sufficient information to analyze the Multicenter CTO Registry in Japan (J-CTO); Prospective Global Registry for the Study of Chronic Total Occlusion Intervention (PROGRESS); Ostial location, Rentrop grade, and Age (ORA); Clinical and Lesion-related Score (CL-score); and EuroCTO Score (CASTLE) success scores. The complication scores were PROGRESS (MACE, mortality, and pericardiocentesis) and Outcomes, Patient health status, and Efficiency iN Chronic Total Occlusion hybrid procedures (OPEN-CTO),OPEN-CLEAN. The J-CTO and CASTLE scores demonstrated the highest areas under the curve (AUC) of 0.718 and 0.703, respectively. The AUC value for the CL-score was 0.685, whereas the PROGRESS score had an AUC of 0.598 and the ORA AUC was 0.545. The level of agreement between scores was low; only 4% of the procedures were classified as difficult or very difficult by all scores and <1% were classified as easy by all 5 scores. Of the complication scores, PROGRESS mortality (AUC 0.651) and PROGRESS MACE (AUC 0.588) showed the best performance, identifying groups with >10% event rate. These results may improve the selection of revascularization techniques, especially for patient demographics that are historically underrepresented in CTO research.

Parent-Guided Developmental Intervention for Infants With Very Low Birth Weight

Early interventions improve neurodevelopmental outcomes after preterm birth, but few studies of early intervention have focused on preterm infants whose families reside in low- or middle-income countries (LMICs). To evaluate whether parent-guided early intervention improves the neurodevelopmental outcomes of preterm infants in an LMIC. This randomized clinical trial was performed at a high-risk obstetric referral hospital in Brazil, with outcome evaluations by examiners masked to randomization group. Eligibility criteria were (1) birth at the study hospital, (2) residence within 40 km of the birth hospital, and (3) gestational age of less than 32 weeks or birth weight of less than 1500 g. Of 138 enrolled infants, 19 died after randomization and 19 withdrew from the study; all other enrollees (50 per randomization group) were evaluated for the primary outcome. Data were collected from January 1, 2016, to May 31, 2022, and analyzed from June 10 to July 31, 2022. On postnatal day 7, infants were randomized to usual care, consisting of support for lactation, kangaroo care, and routine developmental therapies, or to a parent-guided enhanced developmental intervention, consisting of usual care plus infant massage and enhanced visual stimulation, auditory stimulation, social interactions, and support for motor development, instructed by developmental therapists. The primary outcome was the Bayley Scales of Infant and Toddler Development-Third Edition score at 18 months of age adjusted for prematurity. Among the 100 infants included in the analysis, mean (SD) gestational age was 28.4 (2.2) weeks, and 57 (57%) were male. The mean (SD) gestational age for the intervention group was 28.3 (2.3) weeks; for the usual care group, 28.5 (2.2) weeks. Female infants accounted for 21 infants (42%) of the intervention group and 22 (44%) of the usual care group; male infants, 29 (58%) and 28 (56%), respectively. The enhanced developmental intervention group had higher cognitive scores at 18 months of corrected age (mean [SD], 101.8 [11.9] vs 97.3 [13.5]; mean difference, 4.5 [95% CI, 0.1-8.9]). In this randomized clinical trial of a parent-guided developmental intervention for early cognitive function of very preterm or very low birth weight infants implemented in an LMIC, the intervention improved very preterm infants' neurodevelopmental outcomes at 18 months of adjusted age. Parent-guided early intervention can improve neurodevelopmental outcome of very preterm infants born in LMICs. ClinicalTrials.gov Identifier: NCT02835612.

Maternal health service utilization in the Jimma Zone, Ethiopia: results from a baseline study for mobile phone messaging interventions

BackgroundOver the last 20 years, global healthcare has placed a major focus on improving the survival rates of mothers and children, recognizing the potential to prevent a significant number of deaths resulting from pregnancy and childbirth. Nevertheless, there remains an ongoing obstacle to the insufficient utilization of critical obstetric services to achieve optimal health outcomes for pregnant women. This study aimed to assess the magnitude and determinants of maternal healthcare use in the Jimma Zone, Ethiopia.MethodsData were obtained from a household survey as part of the baseline assessment of a cluster randomized controlled trial. The study participants comprised 588 women in early pregnancy, specifically those with a gestational age of less than 20 weeks. Logistic regression analysis was employed to identify factors associated with the use of maternal health services. Adjusted odds ratios (AORs) were used to assess the strength of the associations, with significance level set at a p-value ≤ 0.05.ResultsThe overall prevalence of maternal health service utilization was 87.9% (CI: 85.1, 90.4) for antenatal care, 74.7% (CI: 73.2, 79.9) for health facility delivery, and 60.4% (CI: 56.4, 64.3) for postnatal care. Multivariable logistic analysis revealed that maternal health service use was significantly influenced by access to health facilities (AOR: 6.6; 95% CI: 2.39, 18.16), financial hardship (AOR: 3; 95% CI: 1.97, 4.61), perceived respectful care (AOR: 2.3; 95% CI: 1.07, 5.11), perceived privacy of service provisions (AOR: 2.4; 95% CI: 1.47, 4.06), and attitudes toward maternal service use (AOR: 2.2; 95% CI: 1.48, 3.24).ConclusionsThe study revealed slightly higher rates of antenatal care, facility delivery, and postpartum care utilization. However, there was a low proportion of early antenatal care initiation, and high rates of antenatal care dropout. Mobile phone-based messaging intervention may enhance maternal health service use by addressing factors such as lack of access, economic challenges, disrespectful care, no privacy of procedures, and unfavorable attitudes.
