Authors: ZHANG Dafang , EARP Brandon E. , BLAZAR Philip , DYER George S. M. 
Published: May 2023

Background: The objective of this study was to assess whether resident involvement in distal radius fracture open reduction internal fixation (ORIF) affect 30-day postoperative complication, hospital readmission, reoperation and operative time. Methods: A retrospective study was performed using the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database by querying the Current Procedural Terminology (CPT) codes for distal radius fracture ORIF from 1 January 2011 to 31 December 2014. A final cohort of 5,693 adult patients who underwent distal radius fracture ORIF during the study period were included. Baseline patient demographics and comorbidities, intraoperative factors, including operative time and 30-day postoperative outcomes, including complications, readmission and reoperations, were collected. Bivariate statistical analyses were performed to identify variable associated with complication, readmission, reoperation and operative time. The significance level was adjusted using a Bonferroni correction as multiple comparisons were performed. Results: In this study of 5,693 patients who underwent distal radius fracture ORIF, 66 patients had a complication, 85 patients were readmitted and 61 patients underwent reoperation within 30 days of surgery. Resident involvement in the surgery was not associated with 30-day postoperative complication, readmission or reoperation, but was associated with longer operative time. Moreover, 30-day postoperative complication was associated with older age, American Society of Anesthesiologists (ASA) classification, chronic obstructive pulmonary disease (COPD), congestive heart failure (CHF), hypertension and bleeding disorder. Thirty-day readmission was associated with older age, ASA classification, diabetes mellitus, COPD, hypertension, bleeding disorder and functional status. Thirty-day reoperation was associated with higher body mass index (BMI). Longer operative time was associated with younger age, male sex and the absence of bleeding disorder. Conclusions: Resident involvement in distal radius fracture ORIF is associated with longer operative time, but no difference in rates of episode-of-care adverse events. Patients may be reassured that resident involvement in distal radius fracture ORIF does not negatively impact short-term outcomes. Level of Evidence: Level IV (Therapeutic)

Background: Reliable methods for measuring range of motion is important for hand therapists. Currently, there is no gold standard for the measurement of thumb metacarpophalangeal joint (MCPJ) hyperextension. We hypothesised that visual and goniometric measurements of thumb MCPJ hyperextension vary greater than 10° from radiographic measurements, and between observers. Methods: Twenty-six fresh-frozen hands were measured by a senior orthopaedic resident and fellowship trained hand surgeon. Passive thumb MCPJ hyperextension was measured by visual estimation, goniometry and axis measurement on a lateral thumb radiograph. Raters were blinded to each other’s and their own prior measurements. Descriptive statistics were recorded for measurement type and inter-observer agreement using a two-way intra-class correlation coefficient (ICC). Intra-observer agreement was calculated using concordance correlation coefficient (CCC). Bland–Altman plots identified trends, systemic differences or potential outliers. Results: Mean measurements for both raters were similar for visual estimation and radiographic measurements. Mean goniometric measurements were twice as high for Rater B, and closer to radiographic measurements. For both raters, mean radiographic measurements were 10° greater than the other two methods. For inter-rater agreement, measurements were within 10° most frequently with radiographic measurement, then visual estimates, and least by goniometer measurements. Rater B had better agreement comparing visual and goniometric to radiographic measurements. Conclusions: Radiographic measurement has the best inter-observer agreement and precision for evaluating passive thumb MCPJ hyperextension, especially considering adjunct corrective procedures when performing a soft-tissue basal joint arthroplasty. Rater experience improves precision, but there is still poor agreement between visual estimates and goniometer measurements compared to radiographic measurements, as the former two underestimate hyperextension by 10°. Development of a standard method of clinical measurement is needed to improve reliability.

Published: May 2023

Background: Little is known regarding the effect timing of repair has on extensor tendon repair results. The purpose of this study is to determine if a relationship exists between the time of extensor tendon injury to extensor tendon repair and patient outcomes. Methods: A retrospective chart review was conducted on all patients that underwent extensor tendon repair at our institution. The minimum time to final follow-up was 8 weeks. Patients were then divided into two cohorts for analysis; those that underwent repair less than 14 days after injury and those that underwent extensor tendon repair at or greater than 14 days after injury. These cohorts were further sub-grouped by zone of injury. Data analysis was then completed using a two-sample t-test assuming unequal variance and ANOVA for categorical data. Results: A total of 137 digits were included in final data analysis, with 110 digits repaired less than 14 days from injury and 27 digits in the greater than or equal to 14 days to surgery group. For zones 1–4 injuries, 38 digits were repaired in the acute surgery group and eight digits in the delayed surgery group. There was no significant difference in final total active motion (TAM) (142.3° vs. 137.4°). Final extension was also similar between the groups (2.37° vs. 2.13°). For zones 5–8 injuries, 73 digits were repaired acutely, and 13 digits were repaired in delayed fashion. There was no significant difference in final TAM (199.4° vs. 172.7°). Final extension was also similar between the groups (6.82° vs. 5.77°). Conclusions: We found time from extensor tendon injury to surgical repair did not affect final range of motion when comparing acute repair within 2 weeks from injury or delayed repair greater than 14 days from injury. Additionally, there was no difference in secondary outcomes, such as return to activity or surgical complications. Level of Evidence: Level IV (Therapeutic)

Published: May 2023

Background: To compare the observed healthcare and societal costs of intramedullary screw (IMS) and plate fixation of extra-articular metacarpal and phalangeal fractures in a contemporary Australian context. Methods: A retrospective analysis, based on previously published data, was performed utilising information from Australian public and private hospitals, the Medicare Benefits Schedule (MBS) and the Australian Bureau of Statistics. Results: Plate fixation demonstrated longer surgical lengths (32 minutes, compared to 25 minutes), greater hardware costs (AUD 1,088 vs. AUD 355), more extended follow-up requirements (6.3 months, compared to 5 months) and higher rates of subsequent hardware removal (24% compared to 4.6%), resulting in an increased healthcare expenditure of AUD 1,519.41 in the public system, and AUD 1,698.59 in the private sector. Wage losses were estimated at AUD 15,515.78 when the fracture cohort is fixed by a plate, and AUD 13,542.43 when using an IMS – a differential of AUD 1,973.35. Conclusions: There is a substantial saving to both the health system and the patient when using IMS fixation over dorsal plating for the fixation of extra-articular metacarpal and phalangeal fractures. Level of Evidence: Level III (Cost Utility)
Wide Resection Preserving Conjoined Tendons of the Rotator Cuff Muscles for Undifferentiated Pleomorphic Sarcoma at the Suprascapular Fossa – A Case Report
Authors: JIN Jin Woo , JUNG Sung Weon , PARK Jun Yong , JEON Jong Min 
Published: May 2023

Surgical principles in sarcoma are a wide resection, including surrounding tissues and maximisation of the function of the affected limb. Rotator cuff muscles are biomechanically important structures acting as a force couple in movement of the shoulder joint. Thus, conjoined tendons are essential for motion capability in absence of the supraspinatus muscle. This article reports a case of a large undifferentiated pleomorphic sarcoma (UPS) at the suprascapular fossa in a 78-year-old man. After diagnosis of sarcoma, he underwent wide, en-bloc excision preserving conjoined tendons of rotator cuff muscles and low-dose radiation therapy for surveillance of local recurrence. All dissection was performed to avoid contaminating the tumour and involved the whole supraspinatus except the conjoined tendons. We report a case of UPS at the suprascapular fossa, which showed a good result after a wide resection preserving conjoined tendons of rotator cuff muscles. Level of Evidence: Level V (Therapeutic)

Published: May 2023

Summary
Three out of four currently accepted species of the genus Reiterina (Rhabditida: Rhabditidae) were described in the early 20th century. The type species of this genus, R. typica (Stefański, 1922) Sudhaus, 2011, has several synonyms, with differences in their individual species descriptions, which necessitates its detailed redescription. A population of this species was isolated from scarab beetles in Hungary and is characterised as follows: body 970 ± 123 μm long in males and 1221 ± 188 μm long in females, V% = 50.1-57.7, female tail conoid (94.5 μm, c = 13, c′ = 3.3), male tail conoid (36 μm, c = 27, c′ = 1.5) with anteriorly opened peloderan bursa supported by nine pairs of genital papillae (1 + 2 + 3 + 3), papillae 4 and 9 open on the dorsal side, and papillae 3 and 8 reaching the edge of the velum, spicules 28-47 μm long. Newly sequenced 18S rDNA genes place Reiterina typica in a clade with other published Reiterina typica sequence and with sequences from the genus Rhabditis.
The Concept of a Religiously Ideal Muslim Woman in Two Treatises on the Customs of Bosnian Muslims
Authors: Duderija Adis 
Published: May 2023

Abstract
The main aim of this article is to examine the construction of a religiously ideal Muslim woman as presented in two sources documenting Bosnian Muslim (Bosniak) customs. The concept of a religiously ideal Muslim woman adopted in this article is based on recent theoretical studies in mainstream Sunnism, which can be arranged into three thematic areas: (i) the nature of female sexuality; (ii) gender segregation and veiling; and (iii) husband-wife dynamics and corresponding gender roles and norms. This article argues that the concept of a religiously ideal Bosnian Muslim woman in the two selected sources strongly reflects the ideal presented in mainstream Sunnism, which are premised upon beliefs that women embody an aggressive socio-morally corrupting sexuality, that upholding strict segregation and veiling is vital, and that husbands hold the locus of authority and control over their wives.
Ambivalent Sexism in the State of Qatar
Authors: Lari Noora 
Published: May 2023

Abstract
This article examines public attitudes toward ambivalent sexism in the State of Qatar, which has taken considerable initiatives to prioritize women’s empowerment strategies and promote equality between men and women. It investigates whether these equality initiatives are reflected in nationals’ attitudes toward women by measuring scores on the Ambivalent Sexism Inventory (ASI). While prior research has focused almost exclusively on the role of social implications, much less has been explored regarding the public sentiments underlying traditional gender roles and patriarchal attitudes in Qatari society. This study uses original survey data from a national sample of a 2019 survey. The results of the novel analytical descriptive approach used here suggest that individuals in Qatar are highly sexist on average, indicating that as a nation, Qatar scores low on gender equality measures. The analysis also reveals that benevolent sexism is evaluated more positively than hostile sexism, although its underlying dimensions correlate with patriarchal views and gender stereotyping in the context of high gender inequality. These findings are especially important considering the ever-emerging dynamics of gender roles and the increased efforts being gradually expended for improved gender parity.

Abstract
Two modes of post-embryonic development, hemianamorphosis and epimorphosis, show a distinct pattern among extant centipede (Chilopoda) orders. Although studies on post-embryonic development in Lithobiomorpha date back to the 19th and the 20th century, many ambiguities referring to nomenclature of their post-embryonic stages still exist. In this paper coherent terminology of the post-embryonic stages in Lithobius melanops, which could be applied to other lithobiomorphs, is proposed. Additionally, morphological variability of selected morphological traits was analyzed using traditional and geometric morphometric approaches. We recognized five anamorphic (anamorph 0 to 4) and five epimorphic stages (agenitalis, immaturus, praematurus, pseudomaturus and maturus). Measurement and count of certain morphometric characters, detailed description of genital appendages, shape and size variation of the forcipular apparatus, the cephalic capsule and the terminal legs are given. Moreover, for the purpose of geometric morphometric analyses we separated specimens of epimorphic stages into three groups (agenitalis-, praematurus- and maturus-like) based on the level of differentiation of genital appendages. Sexual size dimorphism of the forcipular apparatus was observed only in the praematurus group. Also, significant inter-group forcipular size and shape differences are found between some tested groups. Furthermore, significant differences in size and shape were recorded for the cephalic capsule between all groups. Finally, significant size differences in ultimate legs are present between all epimorphic groups, while shape differences were detected only between agenitalis and maturus groups. Our results contribute to overcoming terminological disparities and provide guidelines for distinguishing stages via discrete and continuous changes during post-embryonic development of the anamorphic centipede.
Carlquist’s growth ring classification: a functional approach that reinforces porous and annual rings
Authors: Silva Marcelo dos Santos 
Published: May 2023

Summary
There is no doubt that Carlquist is one of the greatest contemporary wood anatomists. Every student or researcher in the field is likely to have read at least one of his numerous works, and it is difficult to find a topic in wood anatomy that does not lead to one to his publications. Among the many topics addressed by Carlquist are of course growth rings, one of the oldest and most exciting topics in wood anatomy. Carlquist established a functional classification for growth rings based on anatomical variation, in addition to an interpretation of the different anatomical markers “as ecologically adaptive devices.” In this article, I return to Carlquist’s first classification of growth rings and summarize the main changes in his later reviews. I highlight the advances provided by his unprecedented functional approach to growth rings, while also criticizing Carlquist’s proposed growth ring classification, which reinforces a partial view, although dominant until the present day, focused on temperate species: that growth rings are mostly well marked, porous or semi-porous, and with annual periodicity.

Published: May 2023

Idiopathic, non-traumatic, radial artery aneurysms are rare in medical literature. This report presents the case of a 56-year-old man who was incidentally found to have a 1.01 cm × 1.31 cm left radial artery aneurysm during a carpal tunnel workup. The patient had no other aneurysms, nor any known predisposing diseases that could explain his condition. We proceeded with surgical intervention to prevent future complications. We describe the use of a greater saphenous vein interposition graft for the repair of an idiopathic mid-forearm radial artery aneurysm. The patient had an uncomplicated recovery course following repair.

Introduction: Many mental disorders especially chronic serious ones such as schizophrenia-spectrum disorders, are disabling syndromes and impact on patients’ social and cognitive functioning, including work activity. Thus, affected patients may show a particular socio-economic vulnerability and need specific social security as well as rehabilitation interventions, including pensions or job-placements. In Italy, the Working Group named ‘Employment and Social Security/Insurance in Mental Health (ESSIMH)’ was founded in 2020 in order to collect research evidence on mental illness, employment, social security, and rehabilitation. Methods: A descriptive, observational and multi-center study has been conducted in eleven Departments of Mental Health in Italy (Foggia, Brindisi, Putignano, Rome, Bologna, Siena, Pavia, Mantova, Genova, Brescia, and Torino) and involved 737 patients affected by major mental illness and classified in five diagnostic categories: psychoses, mood disorders, personality disorders, anxiety disorders, and others. The data collection was performed in 2020 among patients aged 18 to 70 years old. Results: The rate of employment in our sample was 35.8% ( n = 264). Occupational disability in our sample was recognized in 58.0% of patients with a mean percentage of severity 51.7 ± 43.1; patients with psychoses (73%) reported higher disability followed by personality (60%) and mood disorders (47.3%) ones. In a logistic multivariate modeling, factors significantly associated with diagnosis were (a) higher level of occupational disability in psychoses; (b) higher number of job- placement programs among psychoses patients; (c) lower level of employment in psychoses; (d) more psychotherapy in personality disorder patients; and (e) more years of MHC program in psychoses patients; factors associated with sex were: (a) higher number of drive licenses among males; (b) more physical activity among males; and (c) higher number of job-placement programs among males. Conclusion: patients affected by psychoses were more likely to be unemployed, reported higher occupational disability as well as received more incentives and rehabilitation interventions. These findings confirmed that schizophrenia-spectrum disorders are disabling and patients need psychosocial support and interventions in the framework of a recovery-oriented treatment.

Introduction ExtraCorporeal Membrane Oxygenation (ECMO) in pediatric patients with COVID-19 has a survival rate similar to adults. Occasionally, patients may need to be cannulated by an ECMO team in a referring hospital and transported to an ECMO center. The ECMO transport of a COVID-19 patient has additional risks than normal pediatric ECMO transport for the possible COVID-19 transmissibility to the ECMO team and the reduction of the ECMO team performance due to the need of wearing full personal protective equipment. Since pediatric data on ECMO transport of COVID-19 patients are lacking, we explored the outcomes of the pediatric COVID-19 ECMO transports collected in the EuroECMO COVID_Neo/Ped Survey. Methods We reported five European consecutive ECMO transports of COVID-19 pediatric patients collected in the EuroECMO COVID_Neo/Ped Survey including 52 European neonatal and/or pediatric ECMO centers and endorsed by the EuroELSO from March 2020 till September 2021. Results The ECMO transports were performed for two indications, pediatric ARDS and myocarditis associated to the multisystem inflammatory syndrome related to COVID-19. Cannulation strategies differed among patients according to the age of the patients, transport distance varied between 8 and 390 km with a total transport duration between 5 to 15 h. In all five cases, the ECMO transports were successfully performed without major adverse events. One patient reported a harlequin syndrome and another patient a cannula displacement both without major clinical consequences. Hospital survival was 60% with one patient reporting neurological sequelae. No ECMO team member developed COVID-19 symptoms after the transport. Conclusion Five transports of pediatric patients with COVID-19 supported with ECMO were reported in the EuroECMO COVID_Neo/Ped Survey. All transports were performed by an experienced multidisciplinary ECMO team and were feasible and safe for both the patient and the ECMO team. Further experiences are needed to better characterize these transports and draw insightful conclusions.
