ABSTRACT

OBJECTIVE: The aim of this ambispective cohort study was to examine the effect of instructional methods on dental students’ performance in a preclinical endodontic course. Two cohorts of undergraduate students were included. The pre-pandemic (retrospective) cohort, which had been taught via traditional instruction (live lecture and live demonstration), and the pandemic (prospective) cohort group, which had been taught via a blended learning approach (online/video recorded lecture and video demonstration, combined with practical training in the simulation laboratory).

METHODS: A total of 263 dental students’ competencies and written exam results were reviewed, with 137 students from the traditional and 126 from the blended learning groups. Students’ performances in the competency practical and written exams for both groups were compared. Additionally, a post-course survey was designed to explore the students’ perceptions of blended learning and was sent to the blended learning cohort.

RESULTS: There was a statistically significant difference between both groups in students’ weekly practical project scores. The average score for females was significantly higher than that of males. However, their practical competency exam scores were comparable. On the other hand, the written exam scores were significantly higher in the blended than in the traditional group, with females demonstrating significantly higher written exam scores compared to males (p < 0.001).

CONCLUSION: Blended learning is an effective teaching method for preclinical endodontic courses. It could be more useful than traditional learning methods for the course’s theoretical content. Additionally, the students preferred to continue learning using this model.

ABSTRACT

BACKGROUND: Opioid misuse and addiction among children and adolescents is an increasingly concerning problem. This study sought to determine whether liposomal bupivacaine injectable suspension admixture administered as a single-shot adductor canal peripheral nerve block (SPNB+BL) would decrease utilization of at-home opioid analgesics after anterior cruciate ligament reconstruction (ACLR) in adolescents compared with single-shot peripheral nerve block with bupivacaine (SPNB+B) alone.

METHODS: Consecutive ACLR patients with or without meniscal surgery by a single surgeon were enrolled. All received a preoperative single-shot adductor canal peripheral nerve block with either admixture of liposomal bupivacaine injectable suspension with 0.25% bupivacaine (SPNB+BL) or 0.25% bupivacaine alone (SPNB+B). Postoperative pain management included cryotherapy, oral acetaminophen, and ibuprofen. A prescription for 10 doses of hydrocodone/acetaminophen (5/325 mg) was provided in a sealed envelope with instructions to only use in the case of uncontrolled pain. Pain using the visual analog scale; number of consumed narcotics, acetaminophen, ibuprofen, and pain treatment satisfaction for the first 3 postoperative days were recorded. Statistical analysis was performed.

RESULTS: Fifty-eight patients were enrolled, the average age was 15±1.5 years (SPNB+B=32 patients, SPNB+BL=26 patients). Forty-seven patients (81%) did not require home opioids postoperatively. A significantly lower proportion of patients in the SPNB+BL group required opioids compared with control patients (7.7% vs. 28.1%, P=0.048). Average opioid use was 2 morphine milligram equivalents (MME), 0.4 pills (range, 0 to 20 MME). There were no differences in the visual analog scale or pain treatment satisfaction scores, other demographics, or other operative data. Inverse probability of treatment weighting analysis that was performed to account for any potential group differences revealed home opioid use between groups is significantly different (P<0.001).

CONCLUSIONS: Liposomal bupivacaine injectable suspension admixture administered as an adductor canal nerve block in adolescents undergoing ACLR effectively reduces home opioid usage postoperatively compared with bupivacaine alone.

LEVEL OF EVIDENCE: Level II-prospective comparative study.

ABSTRACT

In health technology assessment (HTA), population-adjusted indirect comparisons (PAICs) are increasingly considered to adjust for the difference in the target population between studies. We aim to assess the conduct and reporting of PAICs in recent HTA practice, by performing, a methodological systematic review of studies implementing PAICs from PubMed, EMBASE Classic, Embase/Ovid Medline All, and Cochrane databases from January 1, 2010 to Feb 13, 2023. Four independent researchers screened the titles, abstracts, and full-texts of the identified records, then extracted data on methodological and reporting characteristics of 106 eligible articles. Most PAIC analyses (96.9%, n = 157) were conducted by (or received funding from) pharmaceutical companies. Prior to adjustment, 44.5% of analyses (n = 72) (partially) aligned the eligibility criteria of different studies to enhance the similarity of their target populations. In 37.0% of analyses (n = 60), the clinical and methodological heterogeneity across studies were extensively assessed. In 9.3% of analyses (n = 15), the quality (or bias) of individual studies was evaluated. Among 18 analyses using methods that required an outcome model specification, results of the model fitting procedure were adequately reported in three analyses (16.7%). These findings suggest that the conduct and reporting of PAICs are remarkably heterogeneous and suboptimal in current practice. More recommendations and guidelines on PAICs are thus warranted to enhance the quality of these analyses in the future.

ABSTRACT

The current study examines the relationships between hitters’ neural activity and their in-game hitting performance. Collegiate baseball players completed a computerized video task assessing whether thrown pitches were balls or strikes while their neural activity was recorded. In addition, each player’s hitting statistics were collected for the following baseball season. Results showed that neural activity during the computerized task was associated with in-game hitting performance, even after accounting for other individual difference variables. These findings indicate that players’ neural activity measured in a laboratory environment shows a translational relationship with in-game hitting performance over time. Neural activity provides a more objective analysis of players’ ongoing self-regulatory processes during hitting and a better understanding of the cognitive processes associated with hitting performance. Self-regulatory cognitive control is adaptable and trainable, and this research advances the measurement of cognitive variables related with in-game hitting performance in baseball.

ABSTRACT

OBJECTIVE: Compare the occurrence of choking and gagging in infants subjected to three complementary feeding (CF) methods.

METHODS: Randomized clinical trial with mother-infant pairs, allocated according to the following methods of CF: a) Parent-Led Weaning (PLW) – group control, b) Baby-Led Introduction to SolidS (BLISS), and c) mixed (initially BLISS and if the infant presents a lack of interest or dissatisfaction, PLW), with the last two methods guided by the infant. Mothers received nutritional intervention on CF and prevention of choking and gagging according to the method at 5.5 months of age and remained in follow-up until 12 months. Frequencies of choking and gagging were collected by questionnaire at nine and 12 months. The comparison between groups was performed using the analysis of variance test (p < 0.05).

RESULTS: 130 infants were followed, and 34 (26.2%) children presented choking between six and 12 months of age, 13 (30.2%) in PLW, 10 (22.2%) BLISS, and 11 (26.2%) mixed method, no significative difference between methods (p > 0.05). The choking was caused mainly by the semi-solid/solid consistency. Moreover, 100 (80%) infants aged from six to 12 months presented gagging and their characteristics were not statistically different among groups (p > 0.05).

CONCLUSION: Infants following a baby-led feeding method that includes advice on minimizing choking risk do not seem more likely to choke than infants following traditional feeding practice that includes advice on minimizing choking risk.

ABSTRACT

OBJECTIVES: Despite early notions that correct attribution of deaths caused by SARS-CoV-2 infection is critical to the understanding of the COVID-19 pandemic, three years later, the accuracy of COVID-19 death counts is still contested. We aimed to compare official death statistics with cause-of-death assessments made in a clinical audit routine by experienced physicians having access to the full medical record.

STUDY DESIGN: Health service quality evaluation.

METHODS: In Östergötland county (pop. 465,000), Sweden, a clinical audit team assessed from the start of the pandemic the cause of death in individuals having deceased after testing positive for SARS-CoV-2. We estimated the concordance between official data on COVID-19 deaths and data from the clinical audit using correlations (r) between the cause-of-death categories and discrepancies between the absolute numbers of categorised deaths.

RESULTS: The concordance between the data sources was poor regarding whether COVID-19 was the underlying or a contributing cause of death. Grouping of the causes increased the correlations to acceptable strength. Also including deaths implicated by a positive SARS-CoV-2 test in the clinical categorisation of COVID-19 deaths reduced the difference in absolute number of deaths; with these modifications, the concordance was acceptable before the COVID-19 vaccination program was initiated (r = 0.97; symmetric mean absolute percentage error (SMAPE) = 19%), while a difference in the absolute numbers of deaths remained in the vaccination period (r = 0.94; SMAPE = 35%).

CONCLUSIONS: This study highlights that carefulness is warranted when COVID-19 death statistics are used in health service planning and resonates a need for further research on cause-of-death recording methodologies.

ABSTRACT

BACKGROUND: Invasive breast carcinomas (IBC) that strongly express SOX10 are almost always negative for androgen receptor (AR). Furthermore, this SOX10+/AR- subset of IBC is nearly always estrogen receptor and progesterone receptor negative (ER-/PR-), being most commonly seen in triple negative breast carcinomas (TNBC), but also in a small subset of HER2+/ER-/PR- IBC. Following our previous work demonstrating the expression of SOX10 in a subset of IBC with “low positive” ER expression (i.e. 1-10 % ER+ staining based on CAP guidelines, here referred to as “ER-low”), we sought to investigate the expression of both SOX10 and AR in a larger cohort of ER-low tumors. As our previous work also revealed occasional SOX10 expression in IBC with >10 % ER+ staining, we also included tumors with any percentage of ER staining, as long as the staining intensity was weak (this subset is referred to as “ER-weak”).

METHODS: We screened cases of HER2-/ER+ IBC diagnosed at our institution over a 10 year period, identified both ER-low and ER-weak tumors and stained both groups with SOX10 and AR.

RESULTS: Strong SOX10 expression was seen in 12/25 (48 %) ER-low tumors and 13/24 (54 %) ER-weak tumors. ER staining in the SOX10+ subset of ER-weak tumors ranged from 15 %-80 % (median 25 %). As expected, AR was negative in all but 1 of the SOX10+ tumors in both groups. While case numbers in these groups were too small for a meaningful statistical analysis, we did note that all SOX10+/AR- tumors within both the ER-low and ER-weak groups were histologic grade 3.

CONCLUSION: The presence of a SOX10+/AR- profile in a significant subset of ER-low tumors confirms the findings of our previous work and provides further support for the proposed functionally ER negative status of this group. Furthermore, the fact that the same SOX10+/AR- profile is seen in a roughly equal subset of ER-weak tumors suggests that a wider range of ER staining may be acceptable as “low positive” in SOX10+/AR- tumors, as long as the ER staining is of weak intensity. However, given the small number of cases in this single institution study, we emphasize the need for larger studies to establish the biological and clinical significance of this tumor subset.

ABSTRACT

The association between major depressive disorder (MDD) and personality traits has been extensively studied. However, differences in personality traits between patients with melancholic MDD (MEL) and nonmelancholic MDD (NMEL) remain unclear. In this study, we aimed to determine whether neuroticism, which has been associated with MDD, and the five affective temperament subtypes assessed by the Temperament Evaluation of Memphis, Pisa, Paris and San Diego-autoquestionnaire version (TEMPS-A) can be used to distinguish MEL and NMEL. A total of 106 patients with MDD (MEL, n = 52; NMEL, n = 54) and 212 age- and sex-matched healthy controls answered the Eysenck Personality Questionnaire-revised and the short version of TEMPS-A. In hierarchical logistic regression analysis, only depressive temperament scores were identified as a statistically significant feature distinguishing NMEL from MEL. Depressive temperament scores assessed by the short version of TEMPS-A were found to be significantly higher in NMEL patients than in MEL patients.

ABSTRACT

OBJECTIVE: The current study aimed to inform the varied and limited research on clinical variables in the context of teletherapy. Questions remain about the comparative quality of therapeutic alliance and clinical outcome in the context of teletherapy compared to in-person treatment.

METHODS: We utilized a cohort design and a noninferiority statistical approach to study a large, matched sample of clients who reported therapeutic alliance as well as psychological distress before every session as part of routine clinical practice at a university counseling center. A cohort of 479 clients undergoing teletherapy after the emergence of the COVID-19 pandemic was compared to a cohort of 479 clients receiving in-person treatment before the onset of the pandemic. Tests of noninferiority were conducted to investigate the absence of meaningful differences between the two modalities of service delivery. Client characteristics were also examined as moderators of the association between modality and alliance or outcome.

RESULTS: Clients receiving teletherapy showed noninferior alliance and clinical outcome when compared to clients receiving in-person psychotherapy. A significant main effect on alliance was found with regard to race and ethnicity. A significant main effect on outcome was found with regard to international student status. Significant interactions on alliance were found between cohort and current financial stress.

CONCLUSIONS: Study findings support the continued use of teletherapy by demonstrating commensurate clinical process and outcome. Yet, it will be important for providers to be aware of existing mental health disparities that continue to accompany psychotherapy – in person and via teletherapy. Results and findings are discussed in terms of research and clinical implications. Future directions for researching teletherapy as a viable treatment delivery method are also discussed.

ABSTRACT

BACKGROUND: Intramuscular cabotegravir (CAB) and rilpivirine (RPV) is the only long-acting antiretroviral therapy (LA-ART) regimen approved for people with HIV (PWH). Long-acting ART holds promise for improving outcomes among populations with barriers to adherence but is only approved for PWH who have virologic suppression with use of oral ART before initiating injectables.

OBJECTIVE: To examine LA-ART in a population of PWH that includes those with viremia.

DESIGN: Observational cohort study.

SETTING: Urban academic safety-net HIV clinic.

PATIENTS: Publicly insured adults living with HIV with and without viral suppression, high rates of unstable housing, mental illness, and substance use.

INTERVENTION: Demonstration project of long-acting injectable CAB-RPV.

MEASUREMENTS: Descriptive statistics summarizing cohort outcomes to date, based on pharmacy team logs and electronic medical record data.

RESULTS: Between June 2021 and November 2022, 133 PWH at the Ward 86 HIV Clinic were started on LA-ART, 76 of whom had virologic suppression while using oral ART and 57 of whom had viremia. The median age was 46 years (IQR, 25 to 68 years); 117 (88%) were cisgender men, 83 (62%) had non-White race, 56 (42%) were experiencing unstable housing or homelessness, and 45 (34%) had substance use. Among those with virologic suppression, 100% (95% CI, 94% to 100%) maintained suppression. Among PWH with viremia, at a median of 33 days, 54 of 57 had viral suppression, 1 showed the expected 2-log₁₀ reduction in HIV RNA level, and 2 experienced early virologic failure. Overall, 97.5% (CI, 89.1% to 99.8%) were projected to achieve virologic suppression by a median of 33 weeks. The current virologic failure rate of 1.5% in the cohort is similar to that across registrational clinical trials at 48 weeks.

LIMITATION: Single-site study.

CONCLUSION: This project demonstrates the ability of LA-ART to achieve virologic suppression among PWH, including those with viremia and challenges to adherence. Further data on the ability of LA-ART to achieve viral suppression in people with barriers to adherence are needed.
