ABSTRACT

OBJECTIVE: We examined the association between partner alcohol consumption and the experience of intimate partner violence among women in Papua New Guinea.

DESIGN: We performed a cross-sectional analyses of data extracted from the 2016-2018 Papua New Guinea Demographic and Health Survey. We included 3319 women in sexual unions. Multilevel binary logistic regression analysis was used to examine the association between partner alcohol consumption and intimate partner violence, controlling for the covariates. Results from the regression analysis were presented using the crude odds ratios (cORs) and adjusted odds ratios (aORs), with 95% confidence intervals (CIs).

SETTING: Papua New Guinea.

PARTICIPANTS: Women aged 15-49 years in sexual unions.

OUTCOME MEASURES: Physical, emotional, and sexual violence.

RESULTS: The prevalence of physical, emotional and sexual violence among women in sexual unions in Papua New Guinea were 45.9% (42.4 to 47.7), 45.1% (43.4 to 46.8) and 24.3% (22.9 to 25.8), respectively. The level of partner alcohol consumption was 57.3%. Women whose partners consumed alcohol were more likely to experience physical violence (aOR=2.86, 95% CI=2.43 to 3.37), emotional violence (aOR=2.89, 95% CI=2.44 to 3.43) and sexual violence (aOR=2.56, 95% CI=2.08 to 3.16) compared with those whose partners did not consume alcohol.

CONCLUSION: This study found a relatively high prevalence of intimate partner violence among women in Papua New Guinea. Most importantly, this study found partner alcohol consumption to be significantly and positively associated with intimate partner violence. The study, therefore, recommends that interventions seeking to reduce intimate partner violence among women in Papua New Guinea should intensify behaviour change and education on reducing or eliminating partner alcohol consumption.

ABSTRACT

BACKGROUND: Online information on mpox (monkeypox) is not well studied. We have analysed the video content, information quality, and audience engagement of mpox-related videos on TikTok.

METHODS: Using a hashtag-based searching strategy, we identified 2462 mpox-related videos on TikTok from 1 January to 11 August 2022; 85 were included after exclusion criteria screening. Videos were evaluated for content on features and treatment of mpox. Video and information quality was assessed using the DISCERN instrument and the Journal of the American Medical Association (JAMA) criteria. We recorded video source, evaluation scores, and viewer engagement metrics. The Kruskal-Wallis test was used for statistical analysis and multiple linear regression for factor-association studies.

RESULTS: Of the 85 videos, two assessed all content topics and highlighted 33% of all content items in clinical guidelines. The overall average score for the videos was 39.56 of 80 on the DISCERN instrument and 1.93 of 4 on the JAMA criteria. No video met all JAMA criteria. Subgroup analysis based on author identity suggested the variance in video scores by source (p<0.05 for all). Overall scores were higher for videos produced by doctors and science communicators than for those made by institutional users, nurses, and the general public. Multiple linear regression analysis showed that having people in the video (69.20, p=0.0001) and including information on treatment choices (1.15, p=0.045) were significant, independent determinants of audience engagement.

CONCLUSION: Public-directed TikTok videos on mpox frequently provide incomplete, inaccurate information, highlighting the potential risks of using TikTok as a health information source.

ABSTRACT

PURPOSE: The aim of this study was to identify the learning needs of spinal surgery patients before hospital discharge. METHODS: This cross-sectional study consisted of 117 spinal surgery patients admitted to the neurosurgery department between October 2019 and March 2020. Data were collected using a descriptive information form, visual analog scale, and the Patient Learning Needs Scale. Data were analyzed using descriptive statistics, Mann-Whitney U and Kruskal-Wallis tests, and Spearman correlation analysis. RESULTS: The mean age of the participants was 54 years, 54.7% were male, and 59% underwent surgery because of spinal disc herniation. The mean Patient Learning Needs Scale score was 188.74. The primary learning needs of the patients were related to the dimensions of activities of living, medication, treatment, and complications, whereas the feelings related to condition were the least-demanded dimension of learning needs. Sex and occupation were the primary factors influencing learning needs. CONCLUSION: The level of learning needs in spinal surgery patients was relatively high. Therefore, discharge education may be planned in line with the learning needs and priorities of these patients, and sex and occupation may be considered while planning discharge education.

ABSTRACT

PURPOSE: Modified barium swallow study (MBSS) is a videofluoroscopic evaluation of oropharyngeal swallowing. Views of esophageal bolus flow during MBSS are permitted under speech-language pathology practice guidelines. However, controversy exists over its implementation. Poor consensus and limited practice guidance may lead to clinical practice variations. Aims of the investigation were to (a) describe current practice patterns of speech-language pathologist visualizing bolus flow through the esophagus during the MBSS, (b) understand areas of variation when incorporating esophageal visualization during the MBSS, and (c) determine clinicians’ willingness to modify MBSS procedures to include esophageal imaging.

METHOD: A web-based survey (Qualtrics XM) consisting of 26 questions was distributed via web posting and e-mail to members of the American Speech-Language-Hearing Association Special Interest Group 13 and Dysphagia Café. The survey was open for 3 months. Descriptive and associative statistics were completed. Field-testing was performed prior to dissemination of the survey to address content validity.

RESULTS: A total of 321 individuals participated; 265 responses were used for analysis. Ninety-three percent of respondents viewed the esophagus during the MBSS. Twelve percent followed to the proximal esophagus, 15% to the mid esophagus, 66% to the lower esophagus, and 6% to varied levels. Variability was also reported in contrast type, volume administered, and nomenclature used. Interestingly, few people (3.61%) disagreed that esophageal visualization should be performed during MBSS.

CONCLUSIONS: Speech-language pathology respondents in this study visualize contrast flow through the esophagus and are enthusiastic about expanding the standard MBSS. However, results of the survey demonstrate a lack of uniformity in assessment practices. Unfortunately, this may impact the diagnostic accuracy and clinical utility when adding esophageal visualization to the MBSS. This study highlights the need for a standardized protocol and identifies current barriers and controversies that may prevent expanding the MBSS to more comprehensively evaluate individuals with dysphagia.

ABSTRACT

BACKGROUND: Persistent instability of the knee is reported in up to 30% of patients after anterior cruciate ligament (ACL) reconstruction. Based on anatomic findings showing that ACL is a flat ribbon-like structure that twists during knee flexion, a new surgical ACL reconstruction technique using a ribbon-like graft has been developed. However the effect of this surgical technique on knee kinematics has not yet been evaluated.

PURPOSE: To compare the anteroposterior and rotational stability of the knee after ACL reconstruction using single-bundle (SB) round and ribbon-like grafts in anterolateral-intact/deficient knees.

STUDY DESIGN: Controlled laboratory study.

METHODS: Twelve human fresh-frozen cadaveric knees were tested with a 6 degrees of freedom robotic system. Internal rotation and anterior translation of the knee were recorded from 0° to 90° of flexion. A full kinematic assessment was performed in each of the following conditions: (1) intact knee, (2) after sectioning of the ACL, (3) after ACL reconstruction using a SB hamstring tendon graft in a round configuration and a ribbon-like configuration, and (4) after sectioning of the anterolateral structures. One-way analysis of variance and post hoc Tukey tests were used for statistical analyses.

RESULTS: When compared with the intact knee, the ACL-deficient knee demonstrated a mean ± SD increase in anterior translation and internal rotation of 6.3 ± 2.5 mm (P < .01) and 5.8°± 2.3° (P < .01), respectively. After ACL reconstruction using a SB ribbon-like graft, the mean difference in anterior translation and internal rotation as compared with the intact knee was -0.1 ± 1.5 mm (P = .842) and 0.0°± 1.1° (P = .999). These differences from the intact knee were also not significant after ACL reconstruction using a round graft (-0.1 ± 1.3 mm, P = .999; -0.5°± 1.5°, P = .401). In the ACL-reconstructed knee using either a ribbon-like or round graft, sectioning of the anterolateral structures did not induce a significant increase of anterior translation and internal rotation of the knee.

CONCLUSION: ACL reconstruction using a SB ribbon-like or round graft restored the kinematics of the intact knee at time zero. Secondary sectioning of the anterolateral structures in the ACL-reconstructed knee using both types of graft did not significantly affect the anterior translation and internal rotation of the knee.

CLINICAL RELEVANCE: This is the first biomechanical study on the new ACL reconstruction technique using a ribbon-like graft.

ABSTRACT

PURPOSE: During motor speech examinations for suspected apraxia of speech (AOS), clients are routinely asked to repeat words several times sequentially. The purpose of this study was to understand the task in terms of the relationship among consecutive attempts. We asked to what extent phonemic accuracy changes across trials and whether the change is predicted by AOS diagnosis and sound production severity.

METHOD: One hundred thirty-three participants were assigned to four diagnostic groups based on quantitative metrics (aphasia plus AOS, aphasia-only, and aphasia with two borderline speech profiles). Each participant produced four multisyllabic words 5 times consecutively. These productions were audio-recorded and transcribed phonetically and then summarized as the proportion of target phonemes that was produced accurately. Nonparametric statistics were used to analyze percent change in accuracy from the first to the last production based on diagnostic group and a broad measure of speech sound accuracy.

RESULTS: Accuracy on the repeated words deteriorated across trials for all groups, showing reduced accuracy from the first to the last repetition for 62% of participants. Although diagnostic groups differed on the broad measure of speech sound accuracy, severity classification based on this measure did not determine degree of deterioration on the repeated words task.

DISCUSSION: Responding to a request to say multisyllabic words 5 times sequentially is challenging for people with aphasia with and without AOS, and as such, performance is prone to errors even with mild impairment. For most, the task does not encourage self-correction. Instead, it promotes errors, regardless of diagnosis, and is, therefore, useful for screening purposes.

ABSTRACT

BACKGROUND: Gender inequity continues to be a major focus of improvements within surgical education. Female trainees are fewer in number and suffer reduced quality of surgical training. Prior studies have demonstrated that surgical autonomy for female trainees in a range of surgical disciplines is less than that of male trainees. As a unique example amongst Australasian specialty training boards, The New Zealand Board of Plastic and Reconstructive Surgery has boasted a gender balanced cohort of surgical trainees since 2013. We sought to examine the effect of gender on surgical autonomy in a cohort of trainees where gender balance has been achieved.

METHODS: A retrospective cohort study was undertaken. Anonymised logbook data for New Zealand plastic surgery trainees was analysed, for the study period, comprising rotations from December 2013 to June 2020. Self-reported levels of trainee supervision were compared against gender. Outcomes were tested using multivariate analysis.

RESULTS: 38 trainees were included in the study (58% Female), with a total of 81,178 cases recorded over the 6.5-year study period. No overall statistically significant difference in surgical autonomy was identified when analysed by gender. Male and female trainees showed similar trends of increasing surgical autonomy throughout the course of surgical training.

CONCLUSIONS AND RELEVANCE: In a cohort of surgical trainees which has reached gender balance, the negative impact of gender on surgical autonomy was not identified. These findings suggest that where women make up an equal proportion of trainees, the implicit gender bias within surgical training may be ameliorated.

ABSTRACT

OBJECTIVE: The contribution of large vessel stenosis to the development of white matter hyperintensities (WMHs) has not been fully elucidated. This study aims to explore the correlation between ipsilateral white matter hyperintensities (WMHs) and the severity of large vessel stenosis in the anterior circulation and cerebral perfusion level, as well as analyze the factors influencing WMHs.

METHODS: A cross-sectional study of 150 patients with unilateral anterior circulation large vessel stenosis of ≥50% was conducted. The severity of ipsilateral WMHs was assessed by Fazekas scale on T2-weighted image and/or fluid-attenuated inversion recovery MR imaging, vascular stenosis severity was evaluated on computed tomography angiography images, and the level of cerebral perfusion was rated according to a staging system for abnormal cerebral perfusion based on CTP results. The relationships between the stenosis severity, cerebral perfusion level and ipsilateral WMHs severity were analyzed. A multivariate logistic regression analysis was performed to determine the factors independently influencing WMHs.

RESULTS: Among 150 patients (mean age, 63.12 ± 10.55 years), there was a statistically significant positive correlation between cerebral perfusion level and the severity of DWMHs and PWMHs (Gamma = 0.561, p < .001; Gamma = 0.600, p < .001), and a positive correlation between cerebral perfusion level and the severity of vascular stenosis (Gamma = 0.495, p < .001).While, there was no statistically significant correlation between the severity of vascular stenosis and the severity of DWMHs and PWMHs (Gamma = 0.188, p = .08; Gamma = 0.196, p = .06). The multivariate logistic regression analysis results demonstrated that age (OR = 1.047, 95% CI 1.003-1.093; p = .035), stroke/TIA history (OR = 2.880, 95% CI 1.154-7.190; p = .023) and stage II of cerebral perfusion (OR = 2.880, 95% CI 1.154-7.190; p = .023) were independent influencing factors on ipsilateral DWMHs. Age (OR = 1.051, 95% CI 1.009-1.094; p = .018), and stage II of cerebral perfusion (OR = 12.871, 95% CI 3.576-46.322; p < .001) were factors independently influencing ipsilateral PWMHs.

CONCLUSION: White matter hyperintensities may be attributed to cerebral hypoperfusion secondary to vascular stenosis but not directly to the severity of stenosis in the large vessels of anterior circulation. Moreover, longitudinal studies with sequential imaging exams may further reveal the impact of cerebral perfusion secondary to vascular stenosis on the development and progression of WMHs.

ABSTRACT

BACKGROUND: Whole-brain longitudinal diffusion studies are crucial to examine changes in structural connectivity in neurodegeneration. Here, we investigated the longitudinal alterations in white matter (WM) microstructure across the timecourse of Huntington’s disease (HD).

METHODS: We examined changes in WM microstructure from premanifest to early manifest disease, using data from two cohorts with different disease burden. The TrackOn-HD study included 67 controls, 67 premanifest, and 10 early manifest HD (baseline and 24-month data); the PADDINGTON study included 33 controls and 49 early manifest HD (baseline and 15-month data). Longitudinal changes in fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity, and radial diffusivity from baseline to last study visit were investigated for each cohort using tract-based spatial statistics. An optimized pipeline was employed to generate participant-specific templates to which diffusion tensor imaging maps were registered and change maps were calculated. We examined longitudinal differences between HD expansion-carriers and controls, and correlations with clinical scores, including the composite UHDRS (cUHDRS).

RESULTS: HD expansion-carriers from TrackOn-HD, with lower disease burden, showed a significant longitudinal decline in FA in the left superior longitudinal fasciculus and an increase in MD across subcortical WM tracts compared to controls, while in manifest HD participants from PADDINGTON, there were significant widespread longitudinal increases in diffusivity compared to controls. Baseline scores in clinical scales including the cUHDRS predicted WM microstructural change in HD expansion-carriers.

CONCLUSION: The present study showed significant longitudinal changes in WM microstructure across the HD timecourse. Changes were evident in larger WM areas and across more metrics as the disease advanced, suggesting a progressive alteration of WM microstructure with disease evolution.

ABSTRACT

PURPOSE: To evaluate in a retrospective practice-based clinical study, the effects of additional laser therapy on side effects following the removal of all four impacted third molars. The secondary objective was, based on those results, to rationalize a protocol for low-level laser therapy (LLLT) in terms of irradiation settings.

METHODS: 96 subjects requiring simultaneous surgical removal of the four third molars were treated from 2017 to 2019. For each subject, one side was randomly assigned to laser treatment, the other receiving the placebo. LLLT was performed by applying an infrared diode laser of 810 nm. In the LLLT irradiated side of the mouth, three groups were randomly assigned to a specific protocol of irradiation. Controllable settings include power, energy density and also scanning technique. The main outcome was pain, registered on a visual analog scale (VAS) performed by the patients.

RESULTS: There was a statistically significant difference for one of the tested protocols. Self-reported annoyance and pain scores were lower for the side submitted to a 30-second laser radiation at a power of 0.3 W with the slow scanning technique (P< 0.05).

CLINICAL SIGNIFICANCE: The present treatment approach, using a one-time low-level laser therapy intra-oral application, showed a beneficial effect of LLLT reducing pain after third molar surgery, which should be confirmed through further study.
