Authors: Lee Wonyong , Tecle Nahom , Knapp Emma , Awad Hani , Oh Irvin 
Published: January 2024

Background: The purpose of this study is to investigate the biomechanical effect of medial displacement calcaneal osteotomy (MDCO), subtalar joint fusion (SF), and medial ligament reconstruction (MLR: deltoid-spring ligament) in a severe flatfoot model. We hypothesized that (1) combination of MDCO and SF improves the tibiotalar and foot alignment in severe progressive collapsing foot deformity (PCFD) cadaver model. (2) However, if a residual valgus heel alignment remains after MCDO and SF, it can lead to increased medial ligament strain, foot malalignment, and tibiotalar valgus tilt, which will be mitigated by the addition of MLR. Methods: Ten fresh-frozen cadaveric foot specimens were used to create a severe flatfoot model. The foot alignment changes, including the talo–first metatarsal angle in the axial and sagittal planes, subtalar angle, and tibiotalar angle in the coronal plane, were measured. The angles were measured at the initial condition, after creating the severe flatfoot model, and after each successive reconstructive procedure in the following order: (1) MDCO, (2) SF, and (3) MLR. Results: Tibiotalar valgus tilt was decreased with the MDCO procedure: 4.4 vs 1.0 degrees ( P = .04). Adding in situ SF to the MDCO led to increased tibiotalar tilt to 2.5 degrees was different from the initial condition ( P = .01). Although the tibiotalar valgus tilt was significantly decreased after adding the MLR to the MDCO/SF procedure compared with the severe flatfoot model (0.8 vs 4.4 degrees, P = .03), no significant difference in the tibiotalar valgus tilt was observed between MDCO/SF and MDCO/SF with MLR. Conclusion: Our results demonstrated that MDCO significantly improved forefoot abduction and medial arch alignment, with no significant additional improvement observed with addition of SF. Following SF, a residual valgus heel alignment can contribute to subsequent tibiotalar valgus tilt. The addition of MLR did not show significantly decreased tibiotalar valgus tilt following SF. Clinical Relevance: Residual valgus heel alignment after subtalar joint fusion in the surgical treatment of PCFD can lead to increased medial ligament strain. Although MLR might be considered for providing medial stability, it may not necessarily prevent the development of tibiotalar valgus tilt.

Introduction: A few months after the beginning of the coronavirus disease of 2019 (COVID-19) vaccination, several reports of myocarditis secondary to the vaccines were published, sometimes with fulminant cases, but until today there is no proven causal link between these 2 events, but with many hypotheses proposed. Methods: A systematic review of current evidence regarding myocarditis after COVID-19 vaccination was performed by searching several databases including PubMed/Medline and Web of Science. The quality of Meta-analysis was assessed using the AMSTAR-2 tool as well as other qualitative criteria. Results: Our umbrella review appraised 4 Meta-analysis of retrospective studies (range: 5-12), The number of vaccine doses included ranged from 12 to 179 million, with the number of myocarditis cases observed ranging from 343 to 1489. All types of vaccines were evaluated, with no exclusions. The overall incidence ranged from 0.89 to 2.36 cases of myocarditis per 100 000 doses of vaccine received. Heterogeny was assessed in 3 of the Meta-analysis, and was highly significant (>75%) in all included studies, and with a significant P-value ( P < .05). Regarding publication bias, 3 of the Meta-analysis conducted the egger and begg regression, with a significant result in only 1. Regarding the assessment of the methodology by the AMSTAR-2 scale indicating that the quality was very critical in 1, low in 2, and moderate in 1 Meta-analysis. Conclusion: The quality of current non-randomized evidence on real causality and incidence of myocarditis after COVID-19 vaccine is still low.
Made to feel different: Families perspectives on external responses to autism and the impacts on family well-being and relationships
Authors: Trew Sebastian 
Published: January 2024

This study aimed to investigate the impact of external factors on the experiences and family relationships of autistic adolescents and their families. A qualitative approach was used, with in-depth interviews conducted with 30 participants, including autistic adolescents, siblings and parents from within families with an autistic adolescent family member. The findings suggest that external factors significantly influence the well-being of autistic adolescents and their families. The school environment was identified as a significant factor, with sensory overload, bullying and adverse interactions with teachers having a negative impact on the mental health and quality of family relationships for participants. In addition, the study highlighted that isolation and stigma were major concerns for families, suggesting a need for public efforts to raise awareness and understanding of autism. The lack of appropriate support and services was also identified as a significant challenge that families face. The study highlights the need for person-centred approaches to service provision, which involves including autistic adolescents and their families in the design and delivery of support and services. The study recommends collaboration among schools, service providers, and families, as well as efforts to promote autism-friendly environments in schools and the broader community. Lay abstract The influence of the environment on different groups of people with disabilities has rarely been studied in the context of neurodevelopmental disabilities, such as autism, in adolescence. This study explored how external responses to autism affect the experiences, outcomes and family relationships of autistic adolescents and their family members, including siblings and parents. This study adds to the knowledge of factors that contribute to the social disadvantage and exclusion autistic adolescents and their families face in their communities. Interviews with 30 participants from families with an autistic adolescent show that external factors greatly impact the well-being of autistic adolescents and their families. The school environment, including sensory overload, bullying and negative interactions with teachers, was found to be a key factor that negatively influenced mental health and family relationships. The study also revealed that isolation and stigma are major concerns for families, indicating the importance of public awareness campaigns to increase understanding of autism. In addition, the lack of adequate support and services presented significant challenges for families. The study emphasises the importance of person-centred approaches to providing services, which involve including autistic individuals and their families in designing and delivering support.

Prospective memory helps us to remember to perform tasks in the future. Prospective memory can be either time or event based. The goal of this study was to determine time- and event-based prospective memory in autistic adults across the life span. Autistic ( n = 82) and non-autistic ( n = 111) adults, aged between 30 and 86 years, performed the lab-based Amsterdam Breakfast Task, and several naturalistic prospective memory tasks. Preregistered analyses (AsPredicted #34249) were performed using classical frequentist as well as Bayesian statistics. On none of the prospective memory tasks, group differences were observed. Our results show no effect of age on naturalistic tasks, but age did affect our lab-based measure, indicative of the age paradox often described in non-autistic adults. Moreover, we found evidence for a parallel age-related effect of lab-based and naturalistic prospective memory in autistic and non-autistic individuals. Lay abstract What is already known: Prospective memory is an important function for daily living. It is the cognitive function that helps you remember that you are meeting your friend for coffee at 2 pm tomorrow, or that you need to take your vitamins after breakfast. This cognitive function is particularly important in autistic adults, but how prospective memory is associated with increasing age, we currently do not know. What this paper adds: Although performance on experimental tasks that measure prospective memory decreases with age, this pattern is similar in autistic and non-autistic adults. No age effects were found for tasks that were performed outside the lab. Autistic adults and non-autistic adults perform similarly on prospective memory, and this performance remains similar when autistic and non-autistic adults age. Implications for practice, research, or policy: While our results show that prospective memory decreased with increasing age, our results do point to parallel development of prospective memory in autistic and non-autistic adults. This finding serves as a reassurance for those individuals concerned that older autistic individuals might show quicker cognitive decline.
Employment Adjustment During the Initial Outbreak of COVID-19: Empirical Evidence from Tourism Workers in Bhutan

Published: January 2024

Even though quantifying the impacts of COVID-19 on jobs and employment has been studied in recent literature worldwide, not much research has attempted to investigate the impacts in terms of employment adjustment, especially during the initial outbreak of the pandemic. Using secondary survey data of 1,320 employees working in the tourism sector in Bhutan as a case study, our multinomial logit model estimations show that female workers were among the most vulnerable group to be asked to reduce some benefits from work, to receive only a partial salary or to leave without pay during the initial outbreak. However, when the situation became more severe (resulting in the laying off of employees), the tourism sector in Bhutan laid off male workers also. Negative impacts on their employment were likely to be found among workers with higher education, the relatively young and married workers. In addition, employment adjustments were also found to vary by tourism sub-sector during initial outbreaks. Workers in the entertainment sector seemed to experience the smallest hit from the initial outbreak since they still received some partial payments or were asked to only temporarily leave their jobs without receiving payment. Some sectors, especially tour guides, tour operations, river rafting and land transport, however, had to lay off their workers during the initial outbreak as those businesses rely mostly on international tourists. This study also discusses the policy recommendations to ensure employment stability during such a crisis in the future. JEL Codes: J23, M51, Z39

Published: January 2024

Objectives: Globally, twenty-three million adolescents aged 15–19 years have an unmet need for sexual and reproductive health services and are at risk of unintended pregnancy. In Sub-Saharan Africa, including Ethiopia, it might be difficult for adolescents to get access to sexual and reproductive health services that are acceptable to use. Privacy, a fear of sharing health concerns, a sociocultural environment, the unfriendliness of current services, and traditional taboos are some of the key reasons. This study aimed to explore the perspectives of service providers and adolescents on the use of sexual and reproductive health services. Methodology: A qualitative phenomenological study was conducted from January to February 2023 in the Tikur Anbessa specialized hospital. Purposive sampling was applied to select the study participants. A total of 17 in-depth interviews (with 7 adolescents and 10 health providers) were held. Instead of relying on the number of participants, data saturation was used. Thematic analysis was employed in analyzing the data. Result: The findings indicate that obstacles to the use of sexual and reproductive health services include challenges related to the availability of resources and accessibility; resistance from religious beliefs, cultural beliefs, and customs; quality and institutional-related challenges; and stigma and discrimination in sexual and reproductive health services, which pose the biggest barrier to health professionals providing standardized sexual and reproductive health services. Conclusion: A multi-pronged approach should be created to overcome these challenges, including community outreach for sexual and reproductive health and increasing awareness of the importance of early access to sexual and reproductive health through appropriate community forums. Existing sexual and reproductive health services are not promoted to adolescents and youth, and a lack of and difficulty getting resources for sexual and reproductive health services should be resolved.

Published: January 2024

Objective: This study aimed to conduct a systematic review and meta-analysis of randomized controlled trials to evaluate the effects of elexacaftor–tezacaftor–ivacaftor (ELX-TEZ-IVA) on patients with cystic fibrosis (CF). Methods: A systematic search was performed in PubMed, Embase, and the Cochrane Library from inception to August 1, 2022. Meta-analysis was conducted using Review Manager 5.3 software. Results: Six studies comprising seven reports involving a total of 1125 CF patients were included. The meta-analyses indicated that ELX-TEZ-IVA significantly improved the percentage predicted forced expiratory volume in 1 s (ppFEV1) by 10.29% (95% confidence interval (CI) (6.44, 14.14), p < 0.00001) and the CF questionnaire-revised respiratory domain (CFQ-R RD) by 14.59 points (95% CI (9.25, 19.94), p < 0.00001) compared to placebo, ivacaftor (IVA), or tezacaftor–ivacaftor (TEZ-IVA). In addition, the ELX-TEZ-IVA group showed significantly lower sweat chloride concentrations by 40.30 mmol/L (95% CI (−49.85, −30.74), p < 0.00001). However, the incidence of adverse events in the ELX-TEZ-IVA group was slightly higher than that in the placebo, IVA, or TEZ-IVA groups. Conclusion: ELX-TEZ-IVA demonstrated efficacy in improving ppFEV1, CFQ-R RD, and sweat chloride concentrations in patients with CF. However, caution should be exercised regarding the incidence of AEs, particularly mild and moderate ones.

Published: January 2024

Case series summary Cystic bronchiectasis was diagnosed in three cats with known histories of chronic coughing using CT and histopathology. CT of the lungs revealed large space-occupying lesions that compressed and displaced unaffected pulmonary parenchyma and vessels. The masses were soft tissue attenuating in two cases and gas-cavitated with areas of dependent fluid in one case. All three cats were found to have mineral attenuating material in lesions and in other dilatated airways. Generalized bronchial wall thickening was also present and indicative of chronic lower airway disease. These findings were supported by histopathology showing inflammatory changes and dilatated airways in the collected tissues. In the two cases in which post-contrast CT series were acquired, the lesions had rim-enhancement. Relevance and novel information Cystic bronchiectasis is a rare presentation of bronchiectasis in cats and may mimic a pulmonary mass lesion, which could be mistaken for neoplasia or abscessation. The lack of central enhancement or presence of gas cavitation on CT, concurrent presence of diffuse bronchial wall thickening, other areas of bronchiectasis and the presence of broncholithiasis may alert the clinician to the possibility of cystic bronchiectasis related to chronic lower airway disease.

Abstract
The hallmark of multiple myeloma (MM) is a clonal plasma cell infiltration in the bone marrow accompanied by myelosuppression and osteolysis. Premalignant stages such as monoclonal gammopathy of undetermined significance (MGUS) and asymptomatic stages such as smoldering myeloma (SMM) can progress to MM. Mesenchymal stromal cells (MSCs) are an integral component of the bone marrow microenvironment and play an important role in osteoblast differentiation and hematopoietic support. Although stromal alterations have been reported in MM contributing to hematopoietic insufficiency and osteolysis, it is not clear whether alterations in MSC already occur in MGUS or SMM. In this study, we analyzed MSCs from MGUS, SMM, and MM regarding their properties and functionality and performed messenger RNA sequencing to find underlying molecular signatures in different disease stages. A high number of senescent cells and a reduced osteogenic differentiation capacity and hematopoietic support were already present in MGUS MSC. As shown by RNA sequencing, there was a broad spectrum of differentially expressed genes including genes of the BMP/TGF-signaling pathway, detected already in MGUS and that clearly increases in patients with SMM and MM. Our data may help to block these signaling pathways in the future to hinder progression to MM.

Abstract
Background
Monoclonal antibodies directed against the neuropeptide calcitonin gene-related peptide (CGRP) are effective in the prevention of chronic and frequent episodic migraine. Since the antibodies do not cross the blood brain barrier, their antinociceptive effect is attributed to effects in meningeal tissues. We aimed to probe if such an antibody can be visualized within the dura mater and the trigeminal ganglia following its administration to rats and to examine if the activity of the trigeminovascular nocisensor complex is influenced by this treatment.

Methods
Effects of the anti-CGRP antibody galcanezumab on the trigeminovascular nocisensor complex was examined by measuring release of sensory neuropeptides and histamine from the rat dura mater. Deposits of galcanezumab were visualized by fluorescence microscopy in the trigeminal ganglion and the dura mater.

Results
Fluorophore-labelled galcanezumab was detected in the dura mater and the trigeminal ganglion up to 30 days after treatment affirming the long-lasting modulatory effect of this antibody. In female rats, seven days after systemic treatment with galcanezumab the capsaicin-induced release of CGRP was decreased, while that of substance P (SP) was increased in the dura mater. In control rats, release of the inhibitory neuropeptide somatostatin (SOM) was higher in females than in males. Stimulation with high concentration of KCl did not significantly change the release of SOM in control animals, while in rats treated with galcanezumab SOM release was slightly reduced. Galcanezumab treatment also reduced the amount of histamine released from dural mast cells upon stimulation with CGRP, while the effect of compound 48/80 on histamine release was not changed.

Conclusions
Galcanezumab treatment is followed by multiple changes in the release of neuropeptides and histamine in the trigeminal nocisensor complex, which may contribute to the migraine preventing effect of anti-CGRP antibodies. These changes affecting the communication between the components of the trigeminal nocisensor complex may reduce pain susceptibility in migraine patients treated with CGRP targeting monoclonal antibodies.

AbstractDespite notable advancements in the investigation and management of lung adenocarcinoma (LUAD), the mortality rate for individuals afflicted with LUAD remains elevated, and attaining an accurate prognosis is challenging. LUAD exhibits intricate genetic and environmental components, and it is plausible that free fatty acid receptors (FFARs) may bridge the genetic and dietary aspects. The objective of this study is to ascertain whether a correlation exists between FFAR4, which functions as the primary receptor for dietary fatty acids, and various characteristics of LUAD, while also delving into the potential underlying mechanism. The findings of this study indicate a decrease in FFAR4 expression in LUAD, with a positive correlation (P < 0.01) between FFAR4 levels and overall patient survival (OS). Receiver operating characteristic (ROC) curve analysis demonstrated a significant diagnostic value [area under the curve (AUC) of 0.933] associated with FFAR4 expression. Functional investigations revealed that the FFAR4-specific agonist (TUG891) effectively suppressed cell proliferation and induced cell cycle arrest. Furthermore, FFAR4 activation resulted in significant metabolic shifts, including a decrease in oxygen consumption rate (OCR) and an increase in extracellular acidification rate (ECAR) in A549 cells. In detail, the activation of FFAR4 has been observed to impact the assembly process of the mitochondrial respiratory chain complex and the malate–aspartate shuttle process, resulting in a decrease in the transition of NAD+ to NADH and the inhibition of LUAD. These discoveries reveal a previously unrecognized function of FFAR4 in the negative regulation of mitochondrial metabolism and the inhibition of LUAD, indicating its potential as a promising therapeutic target for the treatment and diagnosis of LUAD.
