ABSTRACT

OBJECTIVE: Although there is a growing body of literature that discusses the etiology and impact of racial trauma, there are few evidence-based treatment modalities to support BIPOC individuals who have experienced race trauma. Furthermore, current clinicians are ill-equipped to navigate racial trauma symptoms in the therapy due to a dearth in training opportunities during their educational and professional careers. The current study addresses the dearth in racial trauma therapy training opportunities for clinicians through the implementation and evaluation of a training protocol based on the KNIFFLEY Racial Trauma Therapy Model (KRTTM) with community-based clinicians.

METHOD: Fifty-four clinicians who participated in the KRTTM training protocol completed a 7-item efficacy scale as well as a 17-item training satisfaction survey before and at the end of the training.

RESULTS: Results of the paired-samples t-test revealed a statistically significant change in perceived efficacy among clinicians who completed the KRTTM training. Specifically, survey scores among clinicians averaged approximately 22 (i.e., M = 22.2, SD = 4.9) at pretest and 30 (i.e., M = 29.8, SD = 3.7) at posttest, indicating a statistically significant increase in perceived efficacy, t(53), -9.9, p = .000. Further, results of the paired-samples t-test split by race indicated differences in pretest efficacy scores between White (M = 21.7, SD = 4.5) and BIPOC (M = 23.6, SD = 5.9) clinicians in this study.

CONCLUSIONS: Overall, the results from the current study highlight that there is a need for more training on evidenced-based treatment models, to include the KRTTM intervention, to build clinicians’ capacity to provide support to BIPOC individuals who have experienced racial trauma during their lifetimes.

ABSTRACT

OBJECTIVE: City Birth Trauma Scale (City BiTS) is an instrument designed to evaluate and diagnose postpartum posttraumatic stress disorder (PTSD) according to the 5th edition of Diagnostic and Statistical Manual of Mental Disorders (DSM-5). No validated Swedish instrument exists to measure postpartum PTSD according to DSM-5. Therefore, the primary aim of this study was to assess the psychometric properties of the Swedish version of the City BiTS (City BiTS-Swe) and to examine the latent factor structure of postpartum PTSD. The secondary aim was to report the Swedish prevalence of PTSD following childbirth.

METHOD: A total of 619 women, who had given birth at five clinics in the past 6-16 weeks, completed an online version of City BiTS-Swe and the Edinburgh Postnatal Depression Scale (EPDS). Additionally, sociodemographic and medical data were collected. A second questionnaire was answered by 110 women to examine reliability over time.

RESULTS: The confirmatory factor analysis using the two-factor model gave best fit to the data. We found a high internal consistency (α = .89-.87) and good test-retest reliability (ICC = 0.53-0.90). Divergent reliability with EPDS showed significant correlations with satisfying results for the subscale birth-related symptoms (r = .41). We also found discriminant validity concerning mode of birth, parity, gestational age, mental illness, history of traumatic childbirth, and history of traumatic event as expected. The prevalence of PTSD was 3.8%.

CONCLUSIONS: The City BiTS-Swe is a valid and reliable instrument to assess and diagnose PTSD following childbirth. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

ABSTRACT

Ensemble representations have been considered as one of the strategies that the visual system adopts to cope with its limited capacity. Thus, they include various statistical summaries such as mean, variance, and distributional properties and are formed over many stages of visual processing. The present study proposes a population-coding model of ensemble perception to provide a theoretical and computational framework for these various facets of ensemble perception. The proposed model consists of a simple feature layer and a pooling layer. We assumed ensemble representations as population responses in the pooling layer and decoded various statistical properties from population responses. Our model successfully predicted averaging performance in orientation, size, color, and motion direction across different tasks. Furthermore, it predicted variance discrimination performance and the priming effects of feature distributions. Finally, it explained the well-known variance and set-size effects and has a potential for explaining the adaptation and clustering effects.

ABSTRACT

OBJECTIVE: The efficient use of wards intended for elective surgeries is essential to resolve cases on the surgical waiting list. This study aims to estimate the efficiency of ward use in the Chilean public health system between 2018 and 2021.

METHODS: The design was an ecological study. Section A.21 of the database constructed by the monthly statistical summaries that each public health network facility reported to the Ministry of Health between 2018 and 2021 was analyzed. Data from subsections A, E and F were extracted: ward staffing, total elective surgeries by specialty, number and causes of suspension of elective surgeries. Then, the surgical performance during working hours and the percentage of hourly occupancy for a working day was estimated. Additionally, an analysis was made by region with data from 2021.

RESULTS: The percentage of elective wards in use ranged from 81.1% to 94.1%, while those enabled for those staffing ranged from 70.5% to 90.4% during 2018 and 2021. The total number of surgeries was highest in 2019 (n = 416 339), but for 2018, 2020, and 2021 it ranged from 259 000 to 297 000. Suspensions varied between 10.8% (2019) and 6.9% (2021), with the leading cause being patient-related. When analyzing the number of cases canceled monthly by facility, we saw that the leading cause was trade union-related. The maximum throughput of a ward intended for elective surgery was reached in 2019 and was 2.5 surgeries; in 2018, 2020 and 2021, the throughput borders on two surgeries per ward enabled for elective surgery. The percentage of ward time occupied during working hours by contract day varies between 80.7% (2018) and 56.8% (2020).

CONCLUSIONS: All the parameters found and estimated in this study show that there is an inefficient utilization of operating rooms in Chilean public healthcare facilities.

ABSTRACT

BACKGROUND: This study is to evaluate safety and pharmacokinetics (PK) of larsucosterol (DUR-928 or 25HC3S) in subjects with alcohol-associated hepatitis (AH), a devastating acute illness without FDA-approved therapies.

METHOD: This Phase 2a, multicenter, open-label, dose escalation study evaluated safety, PK, and efficacy signals of larsucosterol in 19 clinically diagnosed AH subjects. Based on MELD (Model for End-stage Liver Disease) score, 7 subjects were considered to have moderate AH and 12 to have severe AH. All subjects received 1 or 2 intravenous (IV) infusions (72 hours apart) of larsucosterol at a dose of 30, 90, or 150mg, and were followed for 28 days. Efficacy signals from a subgroup of severe AH subjects were compared with two matched arms of severe AH subjects treated with standard of care (SOC), including corticosteroids (CS), from a contemporaneous study.

RESULTS: All 19 larsucosterol-treated subjects survived the 28-day study. Fourteen (74%) of all subjects including 8 (67%) of the severe AH subjects were discharged ≤72 hours after receiving a single infusion. There were no drug-related serious adverse events (SAEs) nor early terminations due to the treatment. PK profiles were not affected by disease severity. Biochemical parameters improved in most subjects. Serum bilirubin levels declined notably from baseline to Day7 and Day28, and MELD scores were reduced at Day28. The efficacy signals compared favorably with two matched groups treated with SOC. Lille scores at Day7 were <0.45 in 16 of the 18 (89%) subjects with Day7 samples. Lille scores from 8 severe AH subjects who received 30 or 90mg larsucosterol (doses used in Phase 2b trial) were statistically significantly lower (p<0.01) than those severe AH subjects treated with SOC from the contemporaneous study.

CONCLUSION: Larsucosterol was well tolerated at all 3 doses in AH subjects without safety concerns. Data from this pilot study showed promising efficacy signals in AH subjects. Larsucosterol is being evaluated in a Phase 2b multicenter, randomized, double-blinded, placebo-controlled (AHFIRM) trial.

ABSTRACT

Despite the considerable progress of in vivo neural recording techniques, inferring the biophysical mechanisms underlying large scale coordination of brain activity from neural data remains challenging. One obstacle is the difficulty to link high dimensional functional connectivity measures to mechanistic models of network activity. We address this issue by investigating spike-field coupling (SFC) measurements, which quantify the synchronization between, on the one hand, the action potentials produced by neurons, and on the other hand mesoscopic “field” signals, reflecting subthreshold activities at possibly multiple recording sites. As the number of recording sites gets large, the amount of pairwise SFC measurements becomes overwhelmingly challenging to interpret. We develop Generalized Phase Locking Analysis (GPLA) as an interpretable dimensionality reduction of this multivariate SFC. GPLA describes the dominant coupling between field activity and neural ensembles across space and frequencies. We show that GPLA features are biophysically interpretable when used in conjunction with appropriate network models, such that we can identify the influence of underlying circuit properties on these features. We demonstrate the statistical benefits and interpretability of this approach in various computational models and Utah array recordings. The results suggest that GPLA, used jointly with biophysical modeling, can help uncover the contribution of recurrent microcircuits to the spatio-temporal dynamics observed in multi-channel experimental recordings.

ABSTRACT

In Cambodia, goat production and meat consumption are customary among Muslim communities. Recently, goat meat has gained popularity among Cambodians. Goat farmers use a traditional management system, including grazing, requiring minimal labour. The close proximity between humans and animals could increase the risk of zoonotic disease transmission. A serological survey was undertaken to estimate the prevalence of some priority zoonoses and high-impact animal diseases in the Cambodian goat population. A total of 540 samples were collected from goats in six provinces and analysed with commercially available enzyme-linked immunosorbent assays for Brucella species, Q fever (Coxiella burnetii), Foot and Mouth Disease virus non-structural protein (FMDV NSP) and Peste des Petits Ruminants virus (PPRV). True seroprevalences with a 95% Confidence Interval (CI), taking into account imperfect tests, risk factors and odds ratios (ORs), were calculated to better understand the disease distribution and epidemiology. Independent variables used in statistical modellings included sex, body condition score, age, vaccination history, province and commune, while dependent variables were ELISA test results. The overall true prevalence of antibodies to Brucella spp., C. burnetii, FMDV and PPRV, were 0.1% (95% CI 0.0, 1.0), 7.2% (95% CI 5.3, 9.7), 57.7% (95% CI 53.1, 62.3) and 0.0% (95% CI 0.0, 0.0), respectively. There was no identified risk factor for brucellosis and PPR. The two risk factors for C. burnetii seropositivity were sex (p-value = 0.0005) and commune (p-value <0.0001). However, only the OR of C. burnetii seropositive female goat was significant at 9.7 (95% CI 2.7, 35.5) times higher than male. The risk factors of FMD NSP seropositivity were age (p-value = 0.001) and commune (p-value <0.0001). Only the age ‘more than two-year-old’ group with a significant OR of 6.2 (95% CI 2.1, 18.4) using the ‘up to one-year-old’ group as the reference. In summary, Brucella spp. seroprevalence was low, while no evidence of PPRV antibodies was detected in the goat populations. C. burnetii seroprevalence in female goats was significantly higher than for males, and there were significant differences in C. burnetii seroprevalence between communes. The overall FMDV NSP seroprevalence was high, especially in older animals. Vaccination should be advocated to protect animals from FMDV and improve productivity. As the impacts of these zoonoses on human and animal health were still unknown, further investigation of these zoonotic diseases’ epidemiology is recommended.

ABSTRACT

BACKGROUND: Trichomonas vaginalis infection is the most prevalent non-viral sexually transmitted infection (STI) in women and has been suggested as a risk factor for developing cervical cancer.

OBJECTIVE: We aimed to investigate the associations between T. vaginalis infection and cervical carcinogenesis.

SEARCH STRATEGY: A comprehensive systematic search was conducted in five databases on 21 October 2021.

SELECTION CRITERIA: Studies assessing the relationship between T. vaginalis infection, HPV co-infections, cervical dysplasia, and cervical cancer were found eligible.

DATA COLLECTION AND ANALYSIS: Summary estimates for pooled odds ratios (ORs) and their 95% confidence intervals (CIs) were calculated with a random-effects model. Statistical heterogeneity was measured with I² and Cochran’s Q tests.

MAIN RESULTS: The 29 articles included 473 740 women, of whom 8518 were T. vaginalis-positive. Our results showed that T. vaginalis-infected women had 1.79 times higher odds of being diagnosed with HPV co-infection (95% CI 1.27-2.53; I² 95%). We also found that T. vaginalis infection was associated with high-grade squamous intraepithelial lesion diagnosis (OR 2.34, 95% CI 1.10-4.95; I² 75%) and cervical cancer (OR 5.23, 95% CI 3.03-9.04; I² 3%).

CONCLUSIONS: Our results showed an association between T. vaginalis and cervical carcinogenesis in sexually active women.

ABSTRACT

BACKGROUND: Prospective data on maintenance therapy with bevacizumab for persons with NF2-related schwannomatosis (NF2-SWN) is lacking. In this prospective multicenter phase 2 study, we evaluated the efficacy, safety, and tolerability of bevacizumab for maintenance therapy in children and adults with NF2-SWN and hearing loss due to vestibular schwannomas (VS).

METHODS: Following induction therapy, participants received bevacizumab 5 mg/kg every 3 weeks for 18 months. Participants were monitored for changes in hearing, tumor size, and quality of life (QOL), and for adverse events. Hearing loss was defined as a statistically significant decline in word recognition score (WRS) or pure tone average compared to study baseline; tumor growth was defined as >20% increase in volume compared to baseline.

RESULTS: Twenty participants with NF2-SWN (median age 23.5 years; range, 12.5-62.5 years) with hearing loss in the target ear (median WRS 70%, range 2-94%) received maintenance bevacizumab. Freedom from hearing loss in the target ear was 95% after 48 weeks, 89% after 72 weeks, and 70% after 98 weeks. Freedom from tumor growth in the target VS was 94% after 48 weeks, 89% after 72 weeks, and 89% after 98 weeks. NF2-related QOL remained stable for 98 weeks whereas tinnitus-related distress decreased. Maintenance bevacizumab was well tolerated, with three participants (15%) discontinuing treatment due to adverse events.

CONCLUSIONS: Maintenance bevacizumab (5 mg/kg every 3 weeks) is associated with high rates of hearing and tumor stability during 18 months of follow-up. No new unexpected adverse events related to bevacizumab were identified in this population.

ABSTRACT

IMPORTANCE: The prevalence of electronic nicotine delivery systems (ENDS) use has increased, leading to a concern about their respiratory health outcomes. It is unclear whether ENDS use increases the risk of wheezing, a common symptom of respiratory conditions.

OBJECTIVE: To provide an analysis of the longitudinal association between ENDS and cigarette use and self-reported wheezing among US adults.

DESIGN, SETTING, AND PARTICIPANTS: The US nationally representative Population Assessment of Tobacco and Health (PATH) Study was used. Longitudinal data for adults 18 years or older from wave 1 (2013-2014) to wave 5 (2018-2019) were analyzed. Data were analyzed from August 2021 to January 2023.

MAIN OUTCOMES AND MEASURES: The prevalence of self-reported wheezing (waves 2-5) was estimated for 6 strata of tobacco product use (never cigarette and noncurrent ENDS use, never cigarette and current ENDS use, current cigarette and noncurrent ENDS use, current cigarette and current ENDS use, former cigarette and noncurrent ENDS use, and former cigarette and current ENDS use). A generalized estimating equations framework evaluated the association between cigarette and ENDS use and self-reported wheezing at the subsequent wave. An interaction term between cigarette and ENDS use was added to estimate the association between joint cigarette and ENDS use categories and the association of ENDS within strata of cigarette use.

RESULTS: The analytical sample consisted of 17 075 US adults with a mean (SD) age of 45.4 (17) years, of whom 8922 (51%) were female and 10 242 (66%) were Non-Hispanic White. When compared with never cigarette and noncurrent ENDS use, the greatest association in reporting wheezing was for current cigarette and current ENDS use (adjusted odds ratio [AOR], 3.26; 95% CI, 2.82-3.77), which was similar to current cigarette and noncurrent ENDS use (AOR, 3.20; 95% CI, 2.91-3.51) and substantially greater than former cigarette and current ENDS use (AOR, 1.94; 95% CI, 1.57-2.41). Associations were small and not statistically significant for the odds of self-reported wheezing among never cigarette and current ENDS use when compared with never cigarette and noncurrent ENDS use (AOR, 1.20; 95% CI, 0.83-1.72), and for odds of wheezing and current cigarette and current ENDS use when compared with current cigarette and noncurrent ENDS use (AOR, 1.02; 95% CI, 0.91-1.15).

CONCLUSIONS AND RELEVANCE: In this cohort study, exclusive ENDS use was not associated with an increase in the risk of self-reported wheezing. However, a small increase in risk between ENDS use and wheezing was reported by individuals who use cigarettes. This study adds to the literature about the potential health effects associated with ENDS use.
