ABSTRACT

OBJECTIVES/HYPOTHESES: Voice disorders can significantly affect the quality of life. This study aimed to translate, culturally adapt, and validate an Arabic version of the voice disability coping questionnaire (A-VDCQ) for use in Arabic-speaking populations with dysphonia.

STUDY DESIGN: This was a cross-sectional study involving the translation and cultural adaptation of the VDCQ into Arabic. The validation process included reliability and validity assessments. Participants were categorized into cases (individuals with dysphonia) and controls (individuals without dysphonia) to compare coping strategies between the two groups.

METHODS: ccccccccThe 15-item VDCQ was translated from English into Arabic using the forward and backward translation methods. The questionnaire’s reliability was assessed using Cronbach’s alpha and test-retest reliability (intraclass correlation coefficient, ICC). Validity was evaluated by comparing cases and controls using the Mann-Whitney test. Differences in coping strategies across different diagnoses were examined using the Kruskal-Wallis test.

RESULTS: The A-VDCQ demonstrated satisfactory internal consistency (Cronbach’s alpha = 0.769) and excellent test-retest reliability (ICC = 0.993). Significant differences in coping strategies between the cases and controls were also observed (P < 0.001), supporting the instrument’s validity. Notably, item 4, which is related to information seeking, had the highest impact score among the cases. However, no statistically significant differences were found in coping strategies across different diagnoses (P = 0.249).

CONCLUSIONS: The A-VDCQ demonstrated robust psychometric properties for assessing coping strategies in individuals with voice disorders and such strategies’ potential implications for clinical practice and research.

ABSTRACT

OBJECTIVES: This in silico study explored the effects of a wide range of fundamental frequency (f_o), source-spectrum tilt (SST), and vibrato extent (VE) on commonly used frequency and amplitude perturbation and noise measures.

METHOD: Using 53 synthesized tones produced in Madde, the effects of stepwise increases in f_o, intensity (modeled by decreasing SST), and VE on the PRAAT parameters jitter % (local), relative average perturbation (RAP) %, shimmer % (local), amplitude perturbation quotient 3 (APQ3) %, and harmonics-to-noise ratio (HNR) dB were investigated. A secondary experiment was conducted to determine whether any f_o effects on jitter, RAP, shimmer, APQ3, and HNR were stable. A total of 10 sinewaves were synthesized in Sopran from 100 to 1000 Hz using formant frequencies for /a/, /i/, and /u/-like vowels, respectively. All effects were statistically assessed with Kendall’s tau-b and partial correlation.

RESULTS: Increasing f_o resulted in an overall increase in jitter, RAP, shimmer, and APQ3 values, respectively (P < 0.01). Oscillations of the data across the explored f_o range were observed in all measurement outputs. In the Sopran tests, the oscillatory pattern seen in the Madde f_o condition remained and showed differences between vowel conditions. Increasing intensity (decreasing SST) led to reduced pitch and amplitude perturbation and HNR (P < 0.05). Increasing VE led to lower HNR and an almost linear increase of all other measures (P < 0.05).

CONCLUSION: These novel data offer a controlled demonstration for the behavior of jitter (local) %, RAP %, shimmer (local) %, APQ3 %, and HNR (dB) when varying f_o, SST, and VE in synthesized tones. Since humans will vary in all of these aspects in spoken language and vowel phonation, researchers should take potential resonance-harmonics type effects into account when comparing intersubject or preintervention and postintervention data using these measures.

ABSTRACT

Network meta-analysis (NMA) expands upon traditional meta-analysis by integrating three or more interventions. This allows comparing interventions using evidence from trials that have compared pairs of interventions directly, and indirect evidence through common comparators. We provide an overview of NMA concepts and considerations when interpreting results from a systematic review with a NMA and applying them to clinical practice. PATIENT SUMMARY: Network meta-analysis is a statistical tool that allows researchers to compare multiple treatments for a medical condition at once, even when treatments have not been compared to each other in research studies. This mini-review explains how to read a network meta-analysis and apply its results in patient care.

ABSTRACT

PURPOSE: Congenital trochlear nerve palsy is the most common cause of vertical strabismus. The goal of this study was to investigate surgical outcomes after superior oblique tendon plication with or without inferior oblique recession in children and adults with unilateral congenital trochlear nerve palsy.

METHODS: Data and outcomes were collected in patients with a diagnosis of unilateral congenital superior oblique palsy during a retrospective single-center study conducted at the University Hospital of Tours. A reproducible, standard ophthalmological and oculomotor examination was performed pre- and postoperatively at 1 year, including presence or absence of diplopia, vertical and horizontal deviations, and compensatory head posture. Surgical success, defined as an endpoint including absence of diplopia in primary position, absence of head tilt, and vertical deviation at distance fixation<5 prism diopters (PD), was analyzed.

RESULTS: A total of fifty-seven patients (median [IQR] age of 11 years [5-42]) were analyzed. Patients experienced a significant reduction in vertical distance and near deviations (p<0.001), compensatory head tilt (p < 0.001), and diplopia after surgery (p < 0.001). Surgical success was higher in adults (17/24, 70.8%) than in children (15/33, 45.5%), although this did not reach statistical significance (p=0.0657).

CONCLUSION: This study suggests that plication of the superior oblique muscle tendon, with or without recession of the inferior oblique muscle, can be effective in treating unilateral congenital trochlear nerve palsy. Further studies are necessary to compare surgical procedures and investigate their efficacy in adults compared to children in the short and long term.

ABSTRACT

INTRODUCTION: In this study, we aimed to detect changes in posterior segment structures and vascular density caused by COVID-19 using an optical coherence tomography angiography (OCTA) device.

MATERIALS AND METHODS: The study included 20 eyes of 20 patients no systemic or ocular disease who were followed at the Ophthalmology Clinic of Health Sciences University Antalya Training and Research Hospital. The OCTA images of these individuals taken prior to contracting COVID-19 and six months after recovery were examined.

RESULTS: The mean choriocapillaris blood flow was 2.00±0.13mm² before COVID-19 and 2.08±0.23mm² after the disease, and the mean subfoveal choroidal thickness was 247.33±7.65μm before the disease and 273.08±4.92μm after the disease, indicating a statistically significant difference (P=0.003, P=0.001, respectively). The mean retinal nerve fiber layer thickness before and after COVID-19 were 119.33±3.88 and 117.50±3.92μm, respectively, representing a statistically significant decrease (P<0.001).

CONCLUSION: This is the first study in the literature to evaluate the post-COVID-19 changes in the vascular structures of the eye compared to the pre-disease values. In this study, we found statistically significant changes in choriocapillaris blood flow, subfoveal chroidal thickness and retinal nerve fiber layer thickness after COVID-19 infection. Further research with a greater sample size is needed to explore the effect of COVID-19 on these parameters.

ABSTRACT

Bacillus Calmette-Guérin (BCG) Danish strain 1331 (CattleBCG) is currently the lead vaccine candidate for the control of bovine tuberculosis (TB) in cattle in GB, where prior vaccination has shown to result in a significant reduction in bovine TB pathology induced by infection with Mycobacterium bovis (M. bovis). A critical knowledge gap in our understanding of CattleBCG is the duration of immunity post vaccination at the minimum intended vaccine dose. To this end, we performed an experiment where calves were vaccinated with a targeted dose of 10⁶ CFU and, after a period of 52 weeks, experimentally infected with M. bovis. Post mortem examination performed 13 weeks after infection revealed a statistically significant reduction in the severity of TB pathology in the CattleBCG vaccinated group compared with the unvaccinated control group. Additionally, this study allowed us to further assess the diagnostic performance of a defined antigen DIVA reagent (DST-F) developed to detect infected amongst vaccinated animals. Our results demonstrate that when used in a skin test format, DST-F showed high specificity (100 %) in BCG-vaccinated animals when tested prior to infection, whilst detecting all infected animals when re-tested after infection. Furthermore, we also present results supporting the use of the DST-F reagent in an interferon-gamma release assay. In conclusion, the results of this study demonstrate a 52-week duration of immunity following administration of a minimum dose of CattleBCG. This evidence will be a fundamental component in our efforts to apply for UK marketing authorisation to enable vaccination of cattle as a significant additional control measure in the ongoing fight against bovine TB in GB.

ABSTRACT

Influenza vaccination reduces the risk of adverse cardiovascular events.The IAMI trial randomly assigned 2571 patients with acute myocardial infarction (AMI) to receive influenza vaccine or saline placebo during their index hospital admission. It was conducted at 30 centers in 8 countries from October 1, 2016 to March 1, 2020. In this post-hoc exploratory sub-study, we compare the trial outcomes in patients receiving early season vaccination (n = 1188) and late season vaccination (n = 1344).The primary endpoint wasthe composite of all-cause death, myocardial infarction (MI), or stent thrombosis at 12 months. Thecumulative incidence of the primary and key secondary endpoints by randomized treatment and early or late vaccination was estimated using the Kaplan-Meier method. In the early vaccinated group, the primary composite endpoint occurred in 36 participants (6.0%) assigned to influenza vaccine and 49 (8.4%) assigned to placebo (HR 0.69; 95% CI 0.45 to 1.07), compared to 31 participants (4.7%) assigned to influenza vaccine and 42 (6.2%) assigned to placebo (HR 0.74; 95% CI 0.47 to 1.18) in the late vaccinated group (P = 0.848 for interaction on HR scale at 1 year). We observed similar estimates for the key secondary endpoints of all-cause death and CV death. There was no statistically significant difference in vaccine effectiveness against adverse cardiovascular events by timing of vaccination. The effect of vaccination on all-cause death at one year was more pronounced in the group receiving early vaccination (HR 0.50; 95% CI, 0.29 to 0.86) compared late vaccination group (HR 0.75; 35% CI, 0.40 to 1.40) but there was no statistically significant difference between these groups (Interaction P = 0.335). In conclusion,there is insufficient evidence from the trial to establish whether there is a difference in efficacy between early and late vaccinationbut regardless of vaccination timing we strongly recommended influenza vaccination in all patients with cardiovascular diseases.

ABSTRACT

BACKGROUND: Glycated haemoglobin (HbA1c) measurement using Point of Care (POC) testing may be of huge utility, providing convenient testing for early diagnosis and regular monitoring of hard-to-reach patient groups. This systematic review aimed to identify evidence for the successful deployment of these devices to improve patient outcomes in diabetes.

METHODS: A systematic review and meta-analysis was undertaken in February 2023, to identify all relevant articles: (CINAHL, Cochrane, PubMed, Scopus, and Web of Science). Studies were included if they reported outcomes of community POC testing for HbA1c for people with diabetes or at risk of diabetes. The Prospero database and trial registers were searched. Only English language articles were included. Title, abstract screening and full text review was carried out by two reviewers (AG/AR). The Cochrane risk of bias tool for randomised studies and the NIH Quality Assessment tool for observational cohort and cross-sectional studies were used. Publication bias was assessed visually using funnel plot and statistical assessment. We performed a meta-analysis on appropriate studies, applying a fixed effect model. We investigated heterogeneity using visual inspection of forest plots along with evaluative approaches (χ², I²). Strength of evidence was assessed using GRADE.

FINDINGS: 24 studies fulfilled the criteria to be included in the narrative synthesis and 5 could be included in quantitative analysis. 13 studies evaluated HbA1c POC testing in non-diabetic patients, 9 reported results for diabetic patients and 2 included both groups. The narrative synthesis was constructed around 6 key themes: increased test access, diagnosis of people who would otherwise go undiagnosed, intervention/lifestyle change, POC testing effect on HbA1c and glycaemic control, follow-up time and patient satisfaction.

INTERPRETATION: The available published data supports the proposed use of POC devices in a community setting, with positive effects on diabetic care with limited evidence that patients can achieve better glycaemic control.

ABSTRACT

The aim of this study was to find out if experiences of maltreatment in childhood have an effect on the occurrence of temporomandibular joint disorders (TMD). The study was conducted on 380 volunteer adults (252 females and 128 males), with a mean (SD) age of 27.63 (9.06) years. The level of TMD was assessed using the Fonseca Anamnestic Index (FAI). Childhood Trauma Questionnaires (CTQ) were completed by the participants and their marital status and educational level were recorded. FAI scores were significantly higher in females than in males. There was no statistically significant difference between gender and total CTQ score. Moreover, there was no statistically significant difference between educational status, marital status, and total CTQ score. FAI scores correlated positively with total CTQ scores in all individuals. Similarly FAI scores correlated positively with total CTQ scores in males and females. Childhood maltreatment is associated with TMDs. Dentists should be aware that possible collaboration with psychiatrists and/or psychologists when treating patients with TMD could increase the success of their treatment.

ABSTRACT

BACKGROUND: During the Covid-19 pandemic, there has been a notable increase in self-medication with antibiotics or other medications due to impaired access to healthcare services. This kind of self-treatment, without comprehending the condition and its related risks, can result in misdiagnosis, overdosing and delaying in acquiring professional medical attention, or may even cause antimicrobial resistance. Additionally, reports have suggested that medical practitioners have prescribed medications inappropriately to patients with Covid-19. To investigate this further, this study compared the medications used by patients with Covid-19 prior to hospitalization with or without a medical recommendation.

METHODS: Data was extracted a mass survey of patients with of Covid-19 in Mashhad, and the patients were divided into two main groups: those who received medication with guidance from a medical professional (treatment group) and those who self-administered medications without professional oversight (self-treatment group). Statistical analysis was then conducted using SPSS version 26, the Chi-square, and multiple logistic regression test.

RESULTS: This study examined 3266 patients, with 1466 included in the analysis. Results showed that men (9.5 %), those living in rural areas (21 %), and those with no academic degree (37.5%) had a higher likelihood to self-medicating. Antibiotics were the most frequently used medications prior to hospitalization (9.5%). Comparing the two groups revealed that three drug categories- antibiotics, antivirals and other medications (medicines that are not in the other 4 main categories)- were utilized more often in the treatment group than in the self-treatment group, with a p-value of < 0.05. The only medical condition that had a significant difference between the two groups was diabetes, with 34.1 % in the self-treatment group versus 24.5 % in the treatment group (P < 0.05).

CONCLUSIONS: The Covid-19 pandemic has caused a surge in the inappropriate use of certain medications through self-medicating. This poses a serious risk to the health of patients, highlighting the need for not only adjusting guidelines but also raising awareness and enforcing compliance to prevent unnecessary use of drugs.
