ABSTRACT

Grant’s gazelles (Nanger granti) are classified as of least concern by the IUCN, although their number is declining due to several factors. A few research studies have been conducted on Grant’s gazelle in Ethiopia. Thus, the present study was carried out to determine the population size and habitat association of Grant gazelle in the Ene Forest of western Ethiopia, comprising the dry and wet seasons. The study area was stratified into four habitats: woodland, mixed woodland, riverine forest, and grassland habitats. The data were collected using the direct observation technique. The data were analyzed using descriptive statistics and Pearson’s chi-square (χ²) test. The average estimated Grant gazelle population was 136 ± 23 individuals, with a density of 9/km². The adult male-to-adult female sex ratio was 1:1.40 and 1:1.26 during the wet and dry seasons, respectively. The largest herd size (N = 6) was observed during the wet season, and the smallest (N = 4) was observed during the dry season. The highest numbers of Grant gazelles were observed in the grassland habitat during the wet season and in the woodland during the dry season. More Gazelles (N = 65) were observed in the woodland habitat compared to the other habitat types. The continued existence of the Grant’s gazelle population in the area and the suitability of the environment depend significantly on ongoing assessments of habitat change and management intervention.

ABSTRACT

We congratulate Hägg et al. on their study investigating cancer incidence and mortality following first-ever venous thromboembolism (VTE), which provides valuable insights into VTE as a potential marker for underlying malignancies. However, we highlight concerns regarding healthy user bias, the unclear follow-up duration, and inconsistent adjustment in the statistical analysis. We also suggest the use of the Fine-Gray subdistribution hazard model to address competing risks, and the accurate reporting of sex-gender terminology. Lastly, we advise caution in concluding a high incidence of cancer following first-ever VTE without pre-VTE data for comparison and recommend acknowledging potential surveillance bias when interpreting the higher cancer detection rate within 6 months of VTE diagnosis.

ABSTRACT

BACKGROUND: This study aimed to assess the quality and readability of large language model-generated responses to frequently asked questions (FAQs) about Kienböck’s disease (KD).

METHODS: Nineteen FAQs about KD were selected, and the questions were divided into three categories: general knowledge, diagnosis, and treatment. The questions were inputted into the Chat Generative Pre-trained Transformer 4 (ChatGPT4) webpage using the zero-shot prompting method, and the responses were recorded. Hand surgeons with at least 5 years of experience and advanced English proficiency were individually contacted over instant WhatsApp messaging and requested to assess the responses. The quality of each response was analyzed by 33 experienced hand surgeons using the Global Quality Scale (GQS). The readability was assessed with the Flesch-Kincaid Grade Level (FKGL) and Flesch Reading Ease Score (FRES).

RESULTS: The mean GQS score was 4.28 out of a maximum of 5 points. Most raters assessed the quality as good (270 of 627 responses; 43.1%) or excellent (260 of 627 responses; 41.5%). The mean FKGL was 15.5, and the mean FRES was 23.4, both of which are considered above the college graduate level. No statistically significant differences were found in the quality and readability of responses provided for questions related to general knowledge, diagnosis, and treatment.

CONCLUSIONS: ChatGPT-4 provided high-quality responses to FAQs about KD. However, the primary drawback was the poor readability of these responses. By improving the readability of ChatGPT’s output, we can transform it into a valuable information resource for individuals with KD.

LEVEL OF EVIDENCE: Level IV, Observational study.

ABSTRACT

BACKGROUND: The analytical rubric serves as a permanent reference for guidelines on clinical performance for undergraduate dental students. This study aims to assess the rubric system used to evaluate clinical class II composite restorations performed by undergraduate dental students and to explore the impact of gender on overall student performance across two academic years. Additionally, we investigated the relationship between cumulative grade point averages (CGPAs) and students’ clinical performance.

METHODS: An analytical rubric for the assessment of clinical class II composite restoration in the academic years of 2022/2023 and 2023/2024 was used by two evaluators. These two evaluators were trained to use the rubric before doing the evaluations. The scores were based on a 4-point scale for the evaluation of five major parameters for pre-operative procedures (10 points), cavity preparation (20 points), restoration procedures (20 points), and time management (4 points). At the same time, chairside oral exam parameter was 15 points based on a 5-point scale. Descriptive statistics were calculated for the different analytical rubric parameters, and the independent t-test was used to compare the scores between the student groups and the evaluators. Other tests, such as the Kappa test and Pearson’s correlation coefficient, were used to measure the association among CGPA, evaluators, and gender participants.

RESULTS: The overall score out of 69 slightly increased for females/males (61.28/59.42) and (61.18/59.49) in the 2022/2023 and 2023/2024 academic years, respectively, but the differences were not statistically significant. In the 2022/2023 academic year, female students scored significantly higher than male students in pre-operative procedures, as evaluated by both evaluators (p = 0.001), and in time management, as assessed by both evaluators (p = 0.031). The Kappa test demonstrated a moderate to substantial level of agreement between the two evaluators in both academic years. Strong and significant correlations were noted between students’ CGPA and some tested parameters (p = 0.000).

CONCLUSION: The overall performance was very good and high among both genders, but it was marginally higher among females than among males. This study found some differences in performance between male and female students and variability in the evaluations by the two raters ranging from moderate to substantial agreement and similar performances for students with different CGPA.

ABSTRACT

BACKGROUND: Addiction medicine providers have a key role in HIV prevention amidst rising HIV incidence in persons who inject drugs (PWID). Pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) are vastly underutilized in this population. Inpatient hospitalization represents a potential touchpoint for initiation of HIV prophylaxis, though little research explores the role of addiction providers. Here we describe rates of PrEP/PEP delivery to hospitalized PWID seen by an Addiction Consult Service (ACS) at an urban, essential hospital.

METHODS: We performed a cross-sectional study of hospitalized patients who were seen by the ACS from January 1, 2020 to December 31, 2022 and had plausible injection drug use. We calculated the proportion of patients who received a new prescription for PrEP/PEP at discharge. We used descriptive statistics to characterize demographics, substance use, reason for admission, and indications for PrEP/PEP. Secondarily, we calculated the monthly proportion of all patients discharged from the hospital with PrEP/PEP who were seen by the ACS compared to those not seen by the ACS.

RESULTS: The average monthly proportion of ACS consults with plausible injection drug use who received PrEP/PEP was 6.4%. This increased from 4.2% in 2020 to 7.5% in 2022. Those seen by the ACS who received PrEP/PEP had high rates of opioid use disorder (97.5%), stimulant use disorder (77.8%), and homelessness (58.1%); over half were admitted for an injection-related infection. The indications for PrEP/PEP were injection drug use only (70.6%), followed by combined injection and sexual risk (20.2%); 71.9% of prescriptions were for PrEP and 28.1% for PEP. Overall, the ACS was involved in 83.9% of hospital-wide discharges with PrEP/PEP prescriptions (n = 242).

CONCLUSIONS: PWID who were seen by the ACS received PrEP/PEP prescriptions at rates exceeding national averages. The ACS was also involved with the care of the majority of admitted patients who received PrEP/PEP at discharge. While PrEP/PEP use for PWID remains low, the inpatient ACS represents a key resource to improve uptake by leveraging the reachable moment of an inpatient hospitalization.

ABSTRACT

BACKGROUND: Primary screening for high-risk human papillomavirus (hrHPV) with cytological triage for women with non-16/18 hrHPV-positive status has become popular in China. However, cytology relies on the subjective judgment of pathologists, leading to inconsistent clinical performance.

METHODS: A total of 657 hrHPV-positive women aged 25-64 years were enrolled in this cross-sectional study. All participants underwent colposcopic biopsy after cytology triage, with cytology residual specimens undergoing DNA methylation testing. CIN2+ and CIN3+ sensitivity and specificity were compared between the different triage strategies (n=487): PAX1 methylation (PAX1^m) , Glycophorin C methylation (GYPC^m), cytology, and combinations between them or with HPV16/18.

RESULTS: The area under the receiver operating characteristic curves (AUCs) for PAX1^m and GYPC^m in detecting CIN2 or worse (CIN2+) were 0.867 (95% confidence interval [CI]: 0.796-0.937) and 0.873 (95% CI: 0.808-0.938), respectively. The sensitivities of PAX1^m and GYPC^m were consistent with those of cytology for both CIN2+ and CIN3+ detection. The relative specificities of PAX1^m and GYPC^m for CIN2+ detection compared to cytology were 2.83 (95% CI: 2.33-2.45) and 3.09 (95% CI: 2.40-3.98), respectively. The relative specificities of combining HPV 16/18 with PAX1^m and GYPC^m for CIN2+ detection compared to cytology were 3.38 (95% CI: 2.96-3.86) and 3.67 (95% CI: 3.15-4.27), respectively. Compared to low levels of DNA methylation, high levels of PAX1^m and GYPC^m resulted in odd ratios (ORs) of 57.66 (95% CI: 13.57-409.12, p < 0.001) and 23.87 (95% CI: 6.49-115.42, p < 0.001) for CIN3+, adjusted for HPV 16/18 and cytology results.

CONCLUSIONS: PAX1^m and GYPC^m demonstrated superior ability to identify cervical precancerous lesions and cervical cancer, with AUC values exceeding 0.85. For detecting CIN2+/CIN3+ in women with hrHPV-positive status, DNA methylation (combined with HPV 16/18) showed higher specificity than cytology (combined with HPV 16/18) and is a potential molecular biomarker for detecting cervical (pre)cancer.

ABSTRACT

BACKGROUND: Physical exercise is an important method for both the physical and mental health of the senior population. However, excessive exertion can lead to increased risks of falls, severe injuries, and diminished quality of life. Therefore, simple and effective methods for fatigue monitoring during exercise are highly desirable, particularly in community settings. The purpose of this study was to explore the possibility of real-time detection of exercise-induced fatigue using surface Electromyogram (sEMG) features, including the kurtosis and skewness of the Probability Density Function (PDF) in the community settings to solve the issues of low sensitivity and high computational complexity of commonly used sEMG features.

METHODS: sEMG signals from six forearm muscles were recorded during hand grip tasks at 20% maximal voluntary contraction (MVC) task-to-failure contractions from 30 healthy community-dwelling elders at their respective community centers. PDF shape features of the sEMG, namely kurtosis and skewness, were computed from 25 s of non-fatigue stable phase and 25 s of fatigue data for comparison. Statistical tests were conducted to compare and test for the significance of these features. We further proposed a novel fatigue indicator, Temporal-Mean-Kurtosis (TMK) of channel-averaged kurtosis, to detect fatigue with relatively low computational complexity and adequate sensitivity in community settings. ANOVA and post-hoc analyses were performed to examine the performance of TMK.

RESULTS: Statistically significant differences were found between the non-fatigue period and the fatigue period for both kurtosis and skewness, with increasing values when approaching fatigue. TMK was shown to be sensitive in detecting fatigue with respect to time with lower computational complexity than the Sample Entropy.

CONCLUSION: This study investigated PDF shape features of sEMG signals during a handgrip exercise to identify muscle fatigue in older adults in community experiments. Results revealed significant changes in kurtosis upon fatigue, indicating that PDF shape features were suitable convenient detectors of muscle fatigue in community experiments. The proposed indicator, TMK, showed potential sensitivity in tracking muscle fatigue over time in community-based settings with limited computational complexity, highlighting the promise of sEMG’s PDF features in detecting muscle fatigue among the elderly.

ABSTRACT

BACKGROUND: The prevalence of steatotic liver disease (SLD) in patients with type 2 diabetes (T2DM) exceeds 50%. This study aimed to investigate the clinical characteristics of SLD and liver fibrosis in Chinese patients with T2DM.

METHODS: Inpatients from 2021 to 2023 were included in the study. Fatty liver index (FLI) and fibrosis-4 (FIB-4) were calculated to assess hepatic steatosis and fibrosis respectively. Statistical analysis was completed by SPSS v25 and GraphPad Prism v8.0.1.

RESULTS: Of the 1466 participants, about one-third of the patients in T2DM-SLD group were diagnosed with liver fibrosis (LF), and the percentage of patients over 50 years old was 85.9%. Patients with SLD had higher levels of BMI, blood pressure, liver enzymes, fasting blood glucose (FBG), HbA1c, C-peptide, total cholesterol (TC) and triglyceride (TG) (P<0.05 for all). Patients with liver fibrosis had lower TC, TG, hemoglobin (Hb), erythrocyte count (RBC), leukocyte count (WBC) and platelet (PLT) levels (P<0.05 for all). Compared with simple T2DM and SLD-NLF (non-liver fibrosis) groups, for patients over 50 years old, the prevalence of coronary heart disease, stroke, tumor, and diabetic nephropathy was higher in patients with liver fibrosis. Liver fibrosis might be the risk factor of arterial stiffness, stroke, coronary heart disease and numbness based on multivariable logistic regression analysis.

CONCLUSION: Hepatic steatosis and fibrosis were common in patients with T2DM. Liver fibrosis was relevant to many macrovascular and microvascular diabetic complications.

ABSTRACT

Oral malodor negatively impacts a person’s quality of life and may affect up to 50% of the population. The aim of this randomized, placebo and no-product controlled, evaluator-blind, proof-of-concept study was to evaluate the effectiveness and safety of the single use of two experimental lozenges containing the laccase enzyme and green coffee extract (with and without flavor) in reducing intrinsic oral malodor. Following 12 to 16 h of avoidance of oral hygiene,156 generally healthy subjects presented at screening and baseline visits with a mean organoleptic odor intensity (OI) score of ≥ 2 and an OralChroma^TMreading of ≥ 125 parts per billion (ppb) hydrogen sulfide (H2S) gas and were randomly assigned to receive either one of the two experimental lozenges, a placebo lozenge, or no-product. Following the supervised use of the assigned products, subjects’ oral malodor was evaluated using OI assessments and OralChroma^TMmeasurement for volatile sulfur compounds (VSCs) immediately following product use (approximately 5 min), and at 30 min, 1 h, 2 h, 3 h and 4 h. The two experimental lozenges, with and without flavor, showed significant reductions in OI scores compared with the placebo and no-product groups at all time points (p < 0.001). At 5 minutes post-product use, the experimental lozenges, with and without flavor, were significantly better than the no-product group in reducing the VSCs (p < 0.04). The results of individual VSC components (hydrogen sulfide, methyl mercaptan and dimethyl sulfide) were variable; both experimental lozenges notably reduced hydrogen sulfide and methyl mercaptan levels in most post-use assessments. Four minor adverse events were reported, none of which were directly linked to the product. In conclusion, the experimental lozenges, whether flavored or not, were safe and effective in reducing oral malodor over a span of 4 h, based on organoleptic OI scores.&#xD;NCT05950529.
