The curing heating rate is a crucial component influencing the characteristics and curing effect of carbon fiber composites during the molding of carbon fiber reinforced plastic filament wound (CFRP FW). To investigate the relationship between the curing heating rate and CFRP FW’s mechanical and microstructure characteristics, in this study, carbon fiber composites the Navy Ordnance Laboratory (NOL) composite rings and unidirectional plates were prepared with five curing heating rates using wet filament winding, and the specimens were tested in tensile, flexural, and shear. Energy dispersive spectroscopy (EDS) was utilized to analyze the microstructural phases elementally, while scanning electron microscopy (SEM) was employed to characterize the shear section and fracture morphology of the unidirectional plate shear specimens. The findings demonstrated that at a curing heating rate of 2°C/min, the peak tensile strength of 2.26 GPa for NOL rings, 2.28 GPa for unidirectional plates, 38.91 MPa for shear strength, and 32.54 MPa for flexural strength were attained. The microfracture of the shear specimen has a uniform morphology, homogeneous structure, and the highest content of carbon elements. This work provides a way to control the pace of curing heating in order to improve the physical characteristics of fiber-woven parts.

Published: January 2025

Background: Operative management of chronic Achilles tendinopathy with large defects can be surgically challenging. Concerns exist regarding transosseous transfer of the flexor hallucis longus (FHL) tendon because of the shortened lever arm of flexion and weakening of the big toe. The aim of this study was to demonstrate the 2-year outcome of transosseous FHL transfer for the treatment of large Achilles tendon defects. Methods: We retrospectively analyzed 28 patients who underwent FHL transfer. The extent of the defect was measured with magnetic resonance imaging. Outcome parameters were the German Foot Function Index (FFI-D) evaluated at baseline and 6, 12, and 24 months postoperatively, the University of California–Los Angeles (UCLA) activity scale, 2 questions about patient satisfaction, reports on complications, or plantar flexion weakness of the great toe. Results: Mean FFI-D scores of pain and disability improved from 37.2 and 52.3, respectively, at baseline to 6.9 and 15.0, respectively, 24 months postsurgery. ( P < .001). At 24 months, 57% of patients were very satisfied and 25% were satisfied with the current symptoms related to their Achilles tendon. All patients noted a relevant improvement at the 2 year follow-up; 1 patient noted weakness of big toe flexion without relevant functional limitation. Complications occurred in 3 patients in the initial postoperative course (2 with delayed wound healing, and 1 with severe perifocal wound necrosis); all resolved completely. Conclusion: We found transosseous FHL transfer using the long, open harvest method and additional bridging of large Achilles defects to be a successful treatment. The majority of patients experienced a significant improvement in both function and pain level and were satisfied with the outcome. Flexion weakness of the big toe does not appear to be a clinically relevant issue after this treatment for chronic Achilles tendinopathy.

Background: Previous studies have shown that people with multiple sclerosis (MS) had frequent healthcare visits up to 10 years before being diagnosed but with no information from magnetic resonance imaging (MRI) scans of the connection with the radiologically isolated syndrome (RIS). Objective: To analyze healthcare use 3 years before the RIS diagnosis. Methods: We examined healthcare usage before the first scan in RIS cases from 2010 to 2019. RIS subjects were identified from the French National MS observatory and compared to the general population (matched 10:1) and MS patients (matched 4:1). Results: Among 482 RIS individuals, 223 (46.3%) were not linked to the healthcare resources database. The remaining RIS individuals (53.7%) had higher healthcare usage before their RIS diagnosis for issues related to neurology visits, headaches (odds ratio (OR): 3.34, confidence interval (CI): [2.00–5.57], p < 0.0001), and the use of anti-migraine drugs (OR: 2.61, CI: [1.37–4.99], p = 0.004) compared to MS. Conclusion: Only about half of RIS patients had MS-selected healthcare resources, which allowed for data linkage. Those who did seek care before their RIS diagnosis were most commonly known for other neurological comorbidities. These findings do not support the idea of a systemic prodrome before RIS diagnosis.

Published: January 2025

Background: Medically intractable ascites causes substantial distress in patients with palliative disease. Tunneled peritoneal catheters have been established as a feasible treatment option allowing patient-controlled paracentesis in a homecare setting. However, while a range of complications is associated with these drainages, risk factors for complications have not been identified so far. Objectives: To explore potential risk factors associated with complications of tunneled peritoneal catheters. Design: Retrospective observational cohort study. Methods: Single-center cohort comprising 49 patients with palliative disease receiving 57 tunneled peritoneal catheters at a tertiary care hospital. Results: Catheter placement was successful in all patients and associated with low numbers of severe complications. Our data suggest a higher risk for severe late complications in patients with benign disease, with drainage replacement, and when performed by less experienced physicians. Conclusion: Tunneled peritoneal catheters are an effective and safe option to treat symptomatic ascites in patients with end-stage palliative disease. The indication should be carefully considered in patients with benign disease and after removal or dislocation of a previous catheter.

Published: January 2025

Purpose The purpose of the study was to explore the facilitators and barriers of health behaviors in patients with type 2 diabetes (T2D), providing a reference for the development of health behavior interventions programs. Methods A qualitative descriptive research design was adopted, and interviews were conducted with 25 patients with T2D. The interview guide was developed based on the health action process approach theory. The interviews were audio-recorded and transcribed verbatim. Data analysis was performed using thematic analysis. Results Through the analysis of interview data, 2 main themes were identified: facilitators and barriers of health behaviors, comprising 18 subthemes. The facilitators included self-efficacy, outcome expectations, risk perception, intention, action planning, coping planning, emotional regulation, proactive and sustained sense of responsibility, and multidimensional social support. The barriers included insufficient disease awareness, insufficient self-control, impact of social activities, low self-efficacy, accessibility of personal conditions, lack of problem-solving skills, lack of disease management knowledge, lack of social support, and cognitive decline. Conclusions When designing health behavior intervention programs for patients with T2D, it is crucial to consider both facilitators and barriers to enhance the effectiveness of the interventions to encourage patients to adopt healthy lifestyles, improve their quality of life, and reduce the occurrence of complications.

Published: January 2025

Abstract
Background
Peripartum depression is a common but potentially debilitating pregnancy complication. Mobile applications can be used to collect data throughout the pregnancy and postpartum period to improve understanding of early risk indicators.

Aim
This study aimed to improve understanding of why women drop out of a peripartum depression mHealth study, and how we can improve the app design.

Method
Participants who dropped out of the Mom2B study (n = 134) answered closed and open questions on their motives for dropping out of the study, suggestions for improvement, and preferred timeframe of the study. A mix of quantitative and qualitative strategies was used to analyze the responses.

Results
The most common reasons for discontinuation were lack of time, problems with or loss of the pregnancy, the use of other pregnancy applications, surveys being too lengthy, the app draining too much battery, and participants incorrectly believing that their answers were irrelevant for the study. Participants suggested fewer survey moments, more reminders, and a need for more unique content compared to commercially available apps.

Conclusions
Researcher who want to use mHealth designs in peripartum studies need to ensure that their study designs are as time-efficient as possible, remind participants about the study, manage expectations about the study and what is expected of participants throughout the study, design their apps to be attractive in a competitive market, and follow-up with participants who are excluded from the study due to pregnancy complications.

Published: January 2025

Abstract
Background
Consequences of lung injury and inflammation in preterm infants with bronchopulmonary dysplasia (BPD) contribute to prolonged oxygen requirements. Home oxygen therapy (HOT) is an alternative way of respiratory support in infant with BPD. However, there is no consensus on weaning guidelines. Our objective is to identify the median age of HOT discontinuation and the factors that might predict the duration of HOT in a resource poor country.

Methods
All preterm (≤ 36 weeks’ gestation) infants diagnosed with BPD who required HOT after discharged from Ramathibodi Hospital during January 2000 – December 2019 comprised this retrospective study. Timing of HOT withdrawal was identified. Demographic data, severity of BPD, maternal condition, respiratory support, comorbidities, complications, and growth were recorded and analyzed as factors associated of home oxygen withdrawal.

Results
Of 8581 preterm infants born during the 20-year period, 563 (6.6%) had BPD. Among 40 infants treated with HOT, 18 (45%) were successfully weaned from oxygen within 12 months. The median corrected age (CA) of oxygen withdrawal was 13.8 months (8.5, 22.1). Longer duration of total respiratory support, longer length of hospital stay and poor growth determined by weight, length and head circumference were associated with longer duration of HOT. Greater weight gain was associated with a shorter duration of HOT at 12 months CA (adjusted OR, 1.97; 95% CI, 1.13–3.23; p = 0.015).

Conclusions
The median corrected age of oxygen withdrawal in Thai BPD infants was 13.8 months. Severe BPD and poor linear growth were associated with prolonged HOT.

Abstract
Background
Blood and oral fluid-based HIV self-tests are important for reaching the undiagnosed living with HIV. The study objectives were to evaluate the oral fluid-based OraQuick® HIV Self-Test (HIV-ST) performance in comparison to laboratory reference testing; determine if laypersons can correctly perform the HIV-ST; document if intended users can successfully interpret pre-made contrived positive, negative, and invalid results; and document if intended users can understand the key messages in the product labeling.

Methods
This prospective study enrolled consenting adult intended users of HIV self-testing from six community health centres in four Canadian provinces between June 2022 and January 2024. Positive and negative agreement was determined by comparing the results of the HIV self-tests with the results of the laboratory-based “gold standard” Abbott Alinity HIV Antigen/Antibody Combo test. Descriptive statistics were used to summarize usability self-test procedure steps.

Results
Overall, 951 participants were recruited and consented with 911 available for all analyses. With respect to sociodemographics: 84% of participants were between 18–45 years of age, 73% had at least a college education, 48% were Cis-male, 45% were employed; and 26% identified as White, 23% as African, Caribbean or Black, 5% as Indigenous [First Nations, Métis or Inuit], 33% as Asian, and 6% as LatinX. Primary efficacy analysis on the 911 who completed HIV-ST revealed a single confirmed positive participant and a negative percent agreement of 100% (880/880, 95% CI: 99.9–100%) with the comparator method. For usability determination, the average success rate for “critical” steps for completing the test was 94.1%. Approximately 97% of participants found the instructions easy to follow and 98% of participants reported they would use the test again. Of the 465 participants who interpreted the strong positive, weak positive, negative, and invalid pre-made contrived results, the average of correct interpretations ranged from 59–97%

Conclusions
A licensed oral fluid-based HIV self-test in Canada can present an accurate, easy-to-use, and less invasive alternative to blood-based HIV testing. The addition of an oral-fluid self-test along with the current licensed blood-based HIV self-test could help reach the undiagnosed with HIV in Canada and positively impact HIV testing rates overall by offering individuals a choice of self-testing devices.

Authors: Elbarmelgi Mohamed Yehia , Shafik Ali Ahmed , Badee Shady Fathy , Mohamed Osama Refaie , Tamer Mohamed 
Published: January 2025

Abstract
Background and aims
Rectal prolapse (RP) is a debilitating condition and can cause symptoms of fecal incontinence, obstructed defecation, incomplete evacuation of the rectum, and pain. In recent years, there has been increasing evidence that prolapse development is strongly associated with pelvic hiatus (GH) size (normal 4.5 +/- 0.7). Multiple surgical studies have suggested that an enlarged pelvic hiatus may be associated with prolapse recurrence. The main aim of this study is to assess the role of combining levatorplasty -with different rectal prolapse surgeries- on recurrence rate and improvement of symptoms in patients that were treated for rectal prolapse with wide pelvic hiatus.

Patients and methods
Our study is a combined retrospective and prospective cohort study which included sixty patients with rectal prolapse with wide pelvic hiatus, they were divided into two groups (each group thirty patients). One group underwent rectal prolapse repair, the other group underwent rectal prolapse repair with levatorplasty.

Results
Levatorplasty group showed improvement in Wexner score, recurrence rate in comparison to the other group. Both groups showed similar results in postoperative pain and dyspareunia.

Conclusion
Rectal prolapse repair combined with levatorplasty in patients complaining of rectal prolapse with wide pelvic hiatus have better outcome mainly in decreasing recurrence rate.

Abstract
Background
Endodontic treatment aims in the preservation of extremely carious primary teeth. For root canal therapy to be successful, root canals must be properly prepared and effectively irrigated .Therefore, it is necessary to select the proper root canal disinfection method to preserve the primary tooth.

Objective
This research was carried out to compare non-thermal pressure plasma (NTPP), diode laser, propolis, and chlorhexidine (CHX) efficacy for disinfection of deciduous anterior root canals contaminated with Enterococcus Faecalis (E. faecalis) after sterilization by gamma radiation.

Methods
In this study, forty extracted single-rooted primary anterior teeth were used. All teeth were cleaned, disinfected, and stored till use. Gaining access was provided till reaching the orifices of canals, all pulp tissue debris was removed, and root canals of all teeth were prepared. Standardized 8 mm root length was obtained through crown decronation below the cemento-enamel junction. Samples were sterilized by gamma radiation then the bacterial suspension was inoculated inside root canals. Specimens divided into four main groups; ten samples each group. Group I: Samples irrigated with chlorhexidine. Group II: Samples treated with diode laser. Group III: Samples irrigated with Ethanolic extract of propolis. Group IV: Samples treated with NTPP.

Results
A significant difference was found between values measured before and after four irrigation types (p < 0.001) for CHX, Diode Laser, NTPP and (P = 0.035) for Propolis. The highest values of colony reduction measured before and after irrigation were for NTPP (4.06 ± 0.88). Maximum reduction in colony-forming units was recorded in the NTPP group (98.79%), while the lowest reduction in colony-forming units was recorded in Propolis group (81.99%).

Conclusion
All tested methods (CHX, NTPP, Diode laser and Propolis) decreased colony count, with the highest reduction noted in group treated by NTPP and the least reduction noticed in Propolis treated group.
Chromogenic bacterial staining of teeth: a scoping review
Authors: Kumar Mathangi , Madi Medhini , Vineetha Ravindranath , Gopinath Divya 
Published: January 2025

Abstract
Background
The purpose of this scoping review is to understand the etiological, clinical characteristics and treatment of chromogenic staining of teeth and the various management strategies reported in literature. This SR was performed in accordance with the PRISMA 2022 guidelines and was registered in the PROSPERO database (CRD42024565446).

Methods
A systematic electronic search on databases like Scopus, Medline, EMBASE, CINAHL, ProQuest and Web of Science from inception to July 2024 was performed. Two independent reviewers ran the search strategy in the mentioned databases.

Results
A total of 989 articles were obtained from various databases. 21 were included for data extraction of which 2 were case reports, 1 was case series and 18 were research articles. The prevalence of staining due to chromogenic bacteria reported from the included studies ranged from 3.1 to 18.5%. All these studies reported on the typical black color of staining of teeth.

Conclusion
This scoping review reveals sparsity in existing literature regarding the etiological, clinical characteristics and management of chromogenic staining of teeth. Though the role of peculiar oral microbiota is well established, evidence regarding the management strategies to combat these recalcitrant staining remains a strong research question.

Abstract
Background
Study aims were to assess the current state and needs of faculty to inform the design of a formal mentorship program in a large academic Department of Psychiatry.

Methods
A 57- item self-administered online survey questionnaire was distributed to all faculty members.

Results
225 faculty members completed the survey (24%). 68% of respondents had a mentor and reported high satisfaction (mean = 4.3, SD = 1.05) (range 1 to 5). Among those respondents lacking access to mentorship, 65% expressed interest. Open-ended questions indicated that international medical graduates, faculty identifying as minority, women and clinician teachers may lack access to mentorship. PhD faculty felt disadvantaged compared to MD faculty in gaining first authorship (MNon−MD=1.64 ± 0.79 vs. MMD=1.36 ± 0.67; t = 2.51, p = .013); reported more authorship disputes (MNon−MD =1.99 ± 0.91 vs. MMD =1.66 ± 0.76; t = 2.63 p = .009) and experienced questionable scientific integrity concerning colleagues (MNon−MD =2.01 ± 0.92 vs. MMD =1.70 ± 0.81; t = 2.42 p = .017). For both MD and PhD faculty, women were significantly more likely to experience authorship disputes (χ2(2) = 8.67, p = .013). The department was perceived as treating faculty with respect (72% agreed) with 54% agreeing that it embraces diversity (54%). Identified benefits to mentorship included receiving advice about academic promotion, opportunities for career advancement, advocacy, and advice as a researcher, teacher or clinician. Only 26% of mentors received formal training to support their role; 59% expressed interest in education. Respondents supported a more formal, accessible, inclusive program, with training, tools, and a matching strategy based on mentee preferences.

Conclusions
Challenges and inequities were identified with the department’s current ad hoc approach to mentorship. A limitation of the study was the response rate, while similar to response rates of other physician surveys, raises the potential for response bias. In comparing study participants to the department, the sample appeared to provide a fair representation. The study has implications for identifying the need and design of more formal mentorship programs in academic medicine.
