A meta-analysis and critical review of metacognitive accuracy in autism
Authors: Carpenter Katie L , Williams David M 
Published: July 2022

Metacognition refers to cognitions about our own cognitions. In recent years, there has been a concerted effort to examine metacognition among autistic people. The results from these studies have produced a mixed picture, with some concluding that autistic people are just as accurate as typically developing people in judging their own cognitions and others providing evidence of reduced accuracy. The aim of this meta-analysis is to amalgamate this research to obtain a clearer picture of the evidence to date. A total of 17 studies comparing 412 individuals diagnosed with autism and 453 typically developing individuals were included in the meta-analysis. The data revealed a moderate, but heterogeneous, reduction in metacognitive accuracy among autistic individuals in comparison with non-autistic individuals. A critical review of the results suggested that, despite the overall reduction in metacognitive accuracy, performance was not universally diminished among autistic participants across studies. Accuracy may be undiminished on certain types of metacognitive task. Moreover, across all tasks, there was moderate difference in metacognitive accuracy between autistic and non-autistic children, but only a small difference in metacognitive accuracy between autistic and non-autistic adults. Lay Abstract The ability to make accurate judgements about our own and others’ mental states has been widely researched; however, it is unclear how these two abilities relate to each other. This is important given that there is evidence that autistic individuals can have difficulty with accurately judging others’ mental states. Recent evidence suggests that some autistic individuals may also have difficulty accurately judging their own mental states. This may have an impact on various aspects of everyday life but particularly academic success, and therefore it is important that this skill is not overlooked when exploring areas of individual support. The aim of this article is to bring together the research examining autistic individual’s ability of making accurate judgements about their own mental states and to establish whether this is an area that warrants further investigation. The results from this article show that autistic individuals may have difficulty making accurate judgements about their own mental states, although this depends on the type of judgement being made. It also highlighted that while autistic children may have difficulties in some areas, these may improve by adulthood. Overall, this article shows that more research is needed to fully understand where specific difficulties lie and how they may be overcome.

Authors: Dharamsi Miraal S. , Caudle Krysta , Fares Austin , Dunn John 
Published: July 2022

Background: This study reviews the patient demographics, functional outcomes, and complications of trapeziometacarpal arthrodesis as a treatment for arthritis of the first carpometacarpal joint. Methods: A literature search was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines using PubMed and Google Scholar. Articles located by the search were independently assessed by title, abstract, or full article review for inclusion or exclusion. Demographic, outcome, and complication data from included articles were extracted, compiled, and analyzed. Frequency-weighted means and proportions were generated. Results: In total, 21 articles met inclusion and exclusion criteria accounting for 802 patients and 914 thumbs. Average age at time of surgery was 55.4 years, and mean follow-up time was 72.7 months. Arthrodesis techniques include Kirschner-wire fixation (51.3%), plate fixation (24.6%), screw fixation (9.8%), tension band technique (7.1%), staple fixation (7.0%), and none (<0.1%). Mean preoperative Disabilities of the Arm, Shoulder and Hand score was 58 and 25.4 postoperatively (∆ = -32.6 points). Mean preoperative visual analogue scale score was 6.8 and 1.9 postoperatively (∆ = -4.9 points). Mean preoperative grip strength was 15.7 kg, and 23.0 kg postoperatively (∆ = +7.3 kg). In all, 48.7% of thumbs had complications, 15.1% of which were major, while 33.6% were minor. The most common major complication was symptomatic hardware (8.6%) requiring return to the operating room, and the most common minor complications were peritrapezial arthritis (8.5%) and nonunion (8.4%). Conclusions: Arthrodesis for arthritis of the trapeziometacarpal joint is associated with good functional outcomes and low to moderate patient-reported disability and pain scores, but a high complication rate.

Published: July 2022

Background: Recently, the SARS-CoV-2 variant of concern, Omicron (B.1.1.529), was identified as responsible for a novel wave of COVID-19 worldwide. Here, we compared initial clinical features of hospitalized COVID-19 patients during recent wave (Omicron Variant) with those in ancestral variant wave (2020). Methods: This is a cohort study of electronic health record (EHR) data from a signal center in the China. The clinical data of 116 cases of Omicron hospitalized in 2022 and 87 cases hospitalized in 2020 were collected. The comparisons were performed with the Mann–Whitney U test, Fisher exact test or the chi-square test, and multivariable logistic regression analysis. Results: Clinically, compared with 2020-cohort, Omicron-cohort was more inclined to cluster in younger population and had more nonsymptomatic (25.0%) and nonsevere cases, as well as suffered from comparable extrapulmonary complication. Radiologically, although the major computed tomography (CT) findings of both cohorts were ground-glass opacities (GGOs), crazy-paving pattern was relatively less seen in the Omicron-cohort. Based on multiple logistic regression analysis, Omicron-cohort was associated with a lower risk of complaining with fever, the presence of lung opacity, and increased Sequential Organ Failure Assessment (SOFA) score. Conclusion: This study provided the data of different patterns of clinic characteristics and reduced severity from infections that occurred in Omicron variant as compared with the outbreak of the epidemic in 2020 wave (ancestral variant).

Published: July 2022

Background: Knee osteoarthritis–related pain limits physical function and leads to functional disability. Physical activity is one of the central recommendations for the management of knee osteoarthritis. Although concentric muscle activities are often preferred to eccentric ones, the corresponding rationale remains controversial. Objective: To explore the effect of a 6-week exercise program on function, pain, and performance in patients with symptomatic knee osteoarthritis. Methods: Patients with symptomatic knee osteoarthritis were included in the prospective EX-ART project (Walking performance in osteoARThritic subjects: effect of an ECCentric muscle strengthening program) and randomized in a 6-week rehabilitation program including either eccentric or concentric activities. Metrics of interest chosen as end points measured before and after the rehabilitation were WOMAC score, pain, and muscular performance (quadriceps power PMAX and contraction strength MMAX). MRI was also used to assess muscle volume and fat infiltration changes. Results: 30 patients were included in each group; mean age was 74 (±7.6); 69% were women. At week 6, both groups showed a significant improvement in the WOMAC without difference between the two groups ( p = 0.7). No difference between the two groups was identified for the pain reduction ( p = 0.7). A significant improvement in the change in PMAX and MMAX at high velocity ( p = 0.001 and p = 0.002) was observed in the eccentric group only. A vastus medialis hypertrophy was quantified in the eccentric group only ( p = 0.002), whereas fat infiltration in the quadriceps muscles was unchanged. Conclusion: Physical activity, whether eccentric or concentric, has a benefit on function and pain in patients with symptomatic knee osteoarthritis. A few differences have been identified between the two types of rehabilitation. More particularly, a gain in muscle performance and vastus medialis volume was found with eccentric rehabilitation only. Registration: www.ClinicalTrials.gov , registration number NCT03167502.
Frequent and diverse use of electronic health records in the United States: A trend analysis of national surveys
Authors: Zheng Han , Jiang Shaohai 
Published: July 2022

Objective Considering the increasing integration of electronic health records (EHRs) into medical practice by healthcare organizations, it is especially pertinent to understand its actual usage by the general public in recent years. This study aims to explore factors associated with the frequency and diversity of EHR usage in the United States over time. Methods We analyzed three iterations (2017, 2018, and 2019) of the Health Information National Trends Survey (HINTS). HINTS is a national cross-sectional survey conducted by the National Cancer Institute to document attitudes and perceptions about health information access and use among American adults. Results Both frequency and diversity of EHR usage have slightly increased across the years. However, its overall usage still remained low. Three technology-related enablers (access to digital devices, access to the Internet, and perceived usefulness of EHRs) were positively related to EHR usage in all three iterations. In addition, perceived health status was a constant and negative predictor of EHR usage over years. Doctor–patient communication was positively associated with the frequency of EHR usage in two survey waves. Conclusions More initiatives to increase EHR usage in the United States are needed. We advocate for providing affordable Internet access and smartphone to underserved populations; in medical encounters, doctors should have more patient-centered communication, introduce the benefits of EHRs to patients, and promote EHR adoption in terms of frequency and diversity.
The use of play in English as a foreign language classrooms: Chinese teachers’ perspectives
Authors: Mao Wei , Doan Laura K , Handford Victoria 
Published: July 2022

This semi-structured interview study seeks to describe Chinese teachers’ understanding and concerns about the use of play in supporting young children’s English learning. Eight English as a foreign language (EFL) teachers of children aged between 3 to 8 years were involved, including both local teachers and international teachers. Findings reveal that because of the unique feature of EFL learning, structured play-based learning was mainly discussed and favored by teachers. Although teachers showed an inclination of separating learning from play, they believed that play serves a supporting role in maintaining students’ interest and motivation in English learning, which is especially crucial important for young children. However, teachers are concerned that play’s benefits would be considered being neutralized when children get older from parents’ perspectives which will eventually negatively impact teachers’ teaching practices. Teachers also face the barriers of balancing the gap between child’s language abilities and cognitive development in EFL teaching. The findings and discussions raise implications for researchers and practitioners to rethink how to define play. A broader definition of play-based learning will help balance both the needs for academic teaching and the benefits of incorporating play, as well as provide implications for integrating play pedagogy in public school systems.
External Debt and Real Exchange Rate Volatility in South Asia
Authors: Moazzam Md. 
Published: July 2022

This study empirically examines the mechanism that connects debt accumulation to exchange rate volatility through the lens of important macroeconomic variables in South Asian Countries. One of the most influential explanatory factors behind exchange rate volatility is deemed as the flow of external debt for these countries. Using data from the World Development Indicators for the period 1980–2020, it is shown that external debt increases exchange rate volatility, significantly. The model is identified via panel Granger tests for relevant variables, estimated for a wide range of covariates and tested for all possible sources of endogeneity via subsequent robustness analyses.

Published: July 2022

Background: Arthroscopic treatment for labral tears includes debridement and repair. Long-term studies have failed to demonstrate a difference between these treatments in terms of conversion to total hip arthroplasty (THA). Purpose: To investigate 2 different labral treatments, debridement and repair, using an adjusted analysis to evaluate long-term conversion to THA. Study Design: Cohort study; Level of evidence, 3. Methods: This was a retrospective cohort study of patients who underwent hip arthroscopy by a single surgeon between April 2007 and October 2014. Postoperative follow-up information included conversion to THA, patient satisfaction, and patient-reported outcome measures (modified Harris Hip Score; Hip Outcome Score, Activities of Daily Living and Sports Specific subscales; International Hip Outcome Tool; Nonarthritic Hip Score; and Lower Extremity Functional Scale). Results: Of the 204 hips included in the study, 99 (48.5%) underwent labral repair, and 105 (51.5%) underwent debridement. In total, 28 (13.7%) of the 204 patients underwent conversion to THA within 10 years after hip arthroscopy (labral repair: 5 [5.0%] vs labral debridement: 23 [21.9%]). Labral repair was associated with a significantly lower risk of conversion to THA compared with debridement (hazard ratio [HR] = 0.24; 95% CI, 0.07-0.74; P = .014). Additional factors associated with risk of conversion to THA included older age at the time of arthroscopy (HR = 1.06 per year; 95% CI, 1.02-1.11; P = .002) and Tönnis grade (HR = 2.39; CI, 1.14-5.41; P = .026). Abrasion chondroplasty, acetabuloplasty, body mass index, Outerbridge grade, and radiographic femoroacetabular impingement were not found to be significantly associated with risk of THA. No significant difference in patient satisfaction was found between treatment groups, and for patients who did not convert to THA, there was no difference in mean patient-reported outcome scores at final follow-up. Conclusion: Patients who underwent labral repair were less likely to convert to THA compared with patients who underwent labral debridement, despite adjustment for differences in baseline patient characteristics and preexisting pathology. Additional factors associated with a lower rate of hip survival were older age and osteoarthritis at the time of hip arthroscopy.

Published: July 2022

Objective To estimate the impact COVID-19 pandemic on healthcare resource utilization (HCRU) among individuals with major depressive disorder (MDD). Method A retrospective cohort study was conducted to compare HCRU in the twelve months prior to and six months following pandemic onset among 1,318,709 individuals with MDD and propensity-score matched controls. Outcomes were monthly rates of all-cause and MDD-specific outpatient, inpatient, and prescription medication HCRU. Piecewise random effects models were used to adjust for patient-level clustering, trends over time, and pre-pandemic factors. Results In the first month following onset, outpatient HCRU declined with primary care visits down 25.1%. Following this initial decline, outpatient HCRU increased, exceeding pre-pandemic rates within three months. By April 2020, three quarters of all psychotherapy sessions were delivered by telehealth, followed by psychiatry (62.3%), and primary care visits (30.1%). The use of telehealth remained highest for psychotherapy and psychiatry (representing 67.6% and 54.2% of visits, respectively, in September 2020). All-cause partial-day hospitalizations declined 50.5% and remained depressed through July 2020 (down 18.3%). Beginning in the first month post-onset, prescription medication HCRU increased for all antidepressant and antipsychotic medication classes: serotonin modulators ( + 11.8%), bupropion ( + 10.4%), SSRIs ( + 9.0%), SNRIs ( + 8.6%), and atypical antipsychotics ( + 7.5%). Conclusions Following pandemic onset, individuals with MDD realized an immediate, but short-lived, reduction in primary care HCRU. Telehealth use remained elevated through the first six months. The most significant and sustained reduction in HCRU was noted for partial-day hospitalizations and all-cause ED visits.

Published: July 2022

ObjectiveUnilateral hypoglossal nerve stimulation (uniHNS) is an effective treatment for obstructive sleep apnea. Bilateral hypoglossal nerve stimulation (biHNS) is a novel therapeutic option and a different approach to hypoglossal nerve stimulation. The aim of this study was to analyze the clinical outcome of the first 10 biHNS cases vs the first 10 uniHNS cases ever implanted.Study DesignProspective data analysis.SettingInternational multicenter comparative clinical trial.MethodsThe first 10 patients in 2020 who received a biHNS device (Genio System; Nyxoah) and the first 10 patients in 2014 who received a uniHNS system (Inspire II; Inspire Medical Systems) were included. Treatment outcome was evaluated at 3 months after surgery. Data collection included demographics, apnea hypopnea index (AHI), oxygen saturation and desaturation index, Epworth Sleepiness Scale, and adverse events.ResultsThe mean ± SD age was 52.1 ± 9.6 years (biHNS) and 58.3 ± 8.6 years (uniHNS). The mean body mass index was 26.4 ± 5.6 kg/m2 (biHNS) and 26.2 ± 2.2 kg/m2 (uniHNS). The mean preimplantation AHI (biHNS, 39.9 ± 14.8/h; uniHNS, 32.2 ± 11.0/h) decreased in both groups after 3 months (biHNS, 19.2 ± 14.0/h, P =. 008; uniHNS, 13.1 ± 16.8/h, P =. 037) with no significant difference between groups (P =. 720). The mean preimplantation Epworth Sleepiness Scale (biHNS, 11.8 ± 6.2; uniHNS, 11.1 ± 4.9) decreased as well after 3 months (biHNS, 9.4 ± 6.3; uniHNS, 6.0 ± 5.0).ConclusionPreliminary postmarket data suggest that biHNS may be as safe and effective as uniHNS. Long‐term follow‐up in a larger sample size is required to assess the stability of biHNS.
How does housing affect end-of-life care and bereavement in low-income communities? A qualitative study of the experiences of bereaved individuals and service providers in the United Kingdom
Authors: Hansford Lorraine , Thomas Felicity , Wyatt Katrina 
Published: July 2022

Background: Access to affordable, appropriate housing is one of the key social determinants of health, affecting well-being across the lifecourse. However, beyond a recognition that housing quality is linked to place of death, little is known about the ways in which housing status impacts social, emotional, and practical aspects of dying and bereavement. Method: The Checking Out project is a qualitative study aiming to explore the ways in which socio-economic status impacts people’s experiences of, and attitudes towards, death, dying, and bereavement in the United Kingdom. Qualitative interviews were carried out with 14 bereaved individuals with experience of poverty at end of life or in bereavement, and 15 professionals supporting individuals in low-income communities. Interviews were conducted via phone/video call, and data include experiences of end of life and bereavement both before and during the pandemic. Transcripts were examined using thematic analysis. Results: Housing emerged as an important factor affecting people’s experiences, with 7 of the 14 bereaved individuals and all except 1 of the professionals discussing housing-related issues. Participants described ways in which unsuitable housing and housing insecurity impacted practical aspects of dying but also emotional and social well-being at end of life. Housing-related issues affected both patients and their families, though families found it difficult to air these concerns when their relative was dying. Conclusion: The paper demonstrates how trusted professionals are able to advocate or address the issues faced by bereaved individuals and suggests implications for policy and practice. A greater awareness of the potential impact of housing status across public services, including healthcare practitioners, welfare support, and housing providers, could better support patients and practitioners to address these issues proactively. Housing providers and policy-makers should be included as key partners in collaborative public health approaches to palliative care.
Design and Dynamic Analysis of the Recirculating Planetary Roller Screw Mechanism
Authors: Qiao Guan , Liao Rong , Guo Shijie , Shi Zhenghong , Ma Shangjun 
Published: July 2022

AbstractThe recirculating planetary roller screw mechanism (RPRSM) is a transmission mechanism that engages the screw and nut threaded by multiple grooved rollers. In this paper, firstly, the design method of RPRSM nut threadless area is proposed, and the equations related to the structural parameters of nut threadless area are derived. On this basis, the cross-section design method of roller, screw and nut is constructed according to the actual situation of engagements between the screw/nut and the roller. By adjusting the gap between the two beveled edges and that between the arc and the beveled edge, the accuracy of the thread engagements between the screw/nut and the roller can be improved. Secondly, to ensure the engagements of the screw/nut and the roller, the distance equation from the center surface of the different rollers to the end surface of cam ring is given. Thirdly, combined with the working principle and structural composition of RPRSM, the component model is established according to its relevant structural parameters, and the virtual assembly is completed. Finally, the 3D model is imported into the ADAMS simulation software for multi-rigid body dynamics. The dynamic characteristic is analyzed, and the simulated values are compared with the theoretical values. The results show that the contact forces between the screw/nut and the roller are sinusoidal, mainly due to the existence of a small gap between the roller and the carrier. The maximum collision forces between the roller and cam ring are independent from load magnitude. Normally, the collision force between the roller and the carrier increases as the load increases. When RPRSM is in the transmission process, the roller angular speed in nut threadless area begins to appear abruptly, and the position of the maximum change is at the contact between the roller and the convex platform of cam ring. The design of the nut threadless area and the proposed virtual assembly method can provide a theoretical guidance for RPRSM research, as well as a reference for overall performance optimization.
