Authors: Jenkinson Mark R. J. , Cheung Tin C. C. , Witt Johan , Hutt Jonathan R. B. 
Published: February 2024

AimsThe aim of this study is to evaluate whether acetabular retroversion (AR) represents a structural anatomical abnormality of the pelvis or is a functional phenomenon of pelvic positioning in the sagittal plane, and to what extent the changes that result from patient-specific functional position affect the extent of AR.MethodsA comparative radiological study of 19 patients (38 hips) with AR were compared with a control group of 30 asymptomatic patients (60 hips). CT scans were corrected for rotation in the axial and coronal planes, and the sagittal plane was then aligned to the anterior pelvic plane. External rotation of the hemipelvis was assessed using the superior iliac wing and inferior iliac wing angles as well as quadrilateral plate angles, and correlated with cranial and central acetabular version. Sagittal anatomical parameters were also measured and correlated to version measurements. In 12 AR patients (24 hips), the axial measurements were repeated after matching sagittal pelvic rotation with standing and supine anteroposterior radiographs.ResultsAcetabular version was significantly lower and measurements of external rotation of the hemipelvis were significantly increased in the AR group compared to the control group. The AR group also had increased evidence of anterior projection of the iliac wing in the sagittal plane. The acetabular orientation angles were more retroverted in the supine compared to standing position, and the change in acetabular version correlated with the change in sagittal pelvic tilt. An anterior pelvic tilt of 1° correlated with 1.02° of increased cranial retroversion and 0.76° of increased central retroversion.ConclusionThis study has demonstrated that patients with symptomatic AR have both an externally rotated hemipelvis and increased anterior projection of the iliac wing compared to a control group of asymptomatic patients. Functional sagittal pelvic positioning was also found to affect AR in symptomatic patients: the acetabulum was more retroverted in the supine position compared to standing position. Changes in acetabular version correlate with the change in sagittal pelvic tilt. These findings should be taken into account by surgeons when planning acetabular correction for AR with periacetabular osteotomy.Cite this article: Bone Joint J 2024;106-B(2):128–135.

Highlights

Lower variability among replicates is associated with greater reliability for recommending irrigation timing.

Eight metrics were presented for variability comparisons independent of sensor types and calibration accuracy.

One neutron thermalization type tended to be less variable than six dielectric types in a comparison at 0.3 m depth.

One granular matrix type tended to be less variable than one dielectric type in a comparison across the top 1 m of soil.

Abstract. Much of the research on irrigation scheduling sensors, especially soil water sensors, assesses and refines the accuracy of sensor calibrations. However, a sensor with an accurate calibration but high variability among replicates may require a larger-than-acceptable number of replicates for informing recommendations of optimal irrigation timing. To compare the interreplicate variability of sensors across types and calibration accuracy levels, this study presented eight metrics: (1) absolute spread-to-change ratio, (2) shifted spread-to-change ratio, (3) coefficient of change variation, (4) standard deviation of relative value, (5) standard deviation of relative change, (6) standard deviation of absolute triggering date, (7) standard deviation of shifted triggering date, and (8) standard deviation of relative triggering date. These metrics enabled comparisons either by nondimensionalizing sensor measurements or by expressing interreplicate variability in terms of time. For demonstrating their usage and their particularities, the metrics were applied to two datasets that included soil water sensor types such as neutron probe (503DR), dielectric sensor (TDR-315, CS616, CS655, HydraProbe II, 5TE, TEROS 12, Drill &amp; Drop), and granular matrix sensor (Watermark 200SS). The neutron probe in the single-depth dataset and the granular matrix sensor in the multi-depth dataset generally displayed less interreplicate variability than other evaluated sensor types over multiple drying cycles. Future research is suggested to calculate and improve the eight metrics for identifying combinations of sensor types, deployment methods, and data interpretation techniques that minimize interreplicate variability and maximize irrigation scheduling precision.

Highlights

Response surface methodology is suitable for DEM input parameter optimization.

Soil reaction forces reduced at velocity ratios greater than one (1.2-3.9).

Vibration reduced soil reaction forces at the target depth of 350 mm by 70%.

In general, soil reaction forces increase with speed but decrease with frequency.

Abrasive wear predominantly occurred at the tool’s cutting section.

Abstract. The discrete element method (DEM) and response surface methodology (RSM) were used to determine the input parameters and combination of operational factors required for optimizing the Jerusalem artichoke (Helianthus tuberosus L.) harvesting tool in cohesive soil. The DEM soil model consisted of particles with different radii in three shapes calibrated using angle of repose and cone penetration data. Compared with data from a soil bin subsoiler evaluation, the DEM model showed acceptable relative errors for draught force (6.7%), vertical force (4.5%), and furrow width (9.3%). The effects of operational factors, including forward speed, vibration frequency, and amplitude, on response variables such as draught and vertical forces, drawbar power, and abrasive wear were analyzed for three harvesting shovels (S-shape, step-shape, and fork-shape). The ratio of vibratory speed to forward speed (velocity ratio, Vr) was used to analyze the combined effect of the factors. The operational factors significantly affected all the response variables (p&lt;0.05). At Vr &gt; 1 (1.2-3.9), soil reaction forces and drawbar power were considerably reduced. The optimal parameters for minimizing the response variables were 2.5 km h-1 forward speed, 14.5 Hz frequency, 30 mm amplitude, and S-shape shovel at Vr = 3.9. The minimum draught force, vertical force, drawbar power, and Archard wear depth were 4.64 kN, 0.41 kN, 2.64 kW, and 2.36 mm, respectively, at an operating depth of 350 mm. Operating in vibratory mode reduced draught force by 54% with the full width of the implement. Future work should include Jerusalem artichoke tubers in the simulation and experimental validation.

Vocational Didactics: Mapping the Terrain in Swedish Upper Secondary Vocational Education and Training
Authors: Wyszynska Johansson Martina , Andersson Ingela 
Published: February 2024

Purpose: The article focuses on the contribution of didactics and didactic theory as a distinct strand in research on vocational education and training (VET). Empirical research is reviewed to further explore what characterizes vocational didactics in the Swedish context of Upper Secondary VET.
Approach: Semi-structured and flexible review methodology was used to identify didactic research and map its emergent features. An analytic framework was constructed for this purpose and used iteratively throughout the review process. The framework expresses the constitutive simultaneous interdependence of the relationships A-B-C. They refer to A) the ways of how the actors engage with the content as meaning and matter or relationship between the actors and the content, B) the relationship between the actors and the method through interaction with the content, and C) relationship between the methods embedded in work tasks and school assignments and how they underpin the content. A total of 26 sources was identified and thematized as school-based vocational didactics, collaborative vocational didactics, and work-based vocational didactics.
Findings: Four distinct features of vocational didactics in Upper Secondary Vocational Education and Training (USVET) are outlined: 1) Diversification of the use of simulation as a method in school-based education pointing to vocational knowledge and skills 2) broadening of instruction (and reflection) as a method by inclusion of several parties (e.g., supervisors, workplace staff, instructors-practitioners), 3) work tasks as a method pointing to vocational knowledge and skills as content, 4) interaction between several parties using verbal and non-verbal means. Despite a growing interest in the importance of work tasks in their dual affordance of meaning and matter, few sources deal with students' learning processes in alignment with the logic of the production of goods and services.
Conclusion: The analytic framework we have put forth strengthens the conceptual boundaries of vocational didactics from a point of view of profession-related learning objectives (content), actors, and methods involved. Applying the didactic theories to review empirical research on VET strengthens the integrity of vocational didactics as a particular field.

Background
Evidence regarding differences in survival associated with the site of metastasis in triple-negative breast cancer (TNBC) remains limited. Our aim was to analyze the overall survival (OS), distant relapse free survival (DRFS), and survival since the diagnosis of the relapse (MS), according to the side of metastasis.

Methods
This was a retrospective study of TNBC patients with distant metastases at the Instituto Nacional de Enfermedades Neoplasicas (Lima, Peru) from 2000 to 2014. Prognostic factors were determined by multivariate Cox regression analysis.

Results
In total, 309 patients were included. Regarding the type of metastasis, visceral metastasis accounted for 41% and the lung was the most frequent first site of metastasis (33.3%). With a median follow-up of 10.2 years, the 5-year DRFS and OS were 10% and 26%, respectively. N staging (N2-N3 vs. N0, HR = 1.49, 95%CI: 1.04–2.14), metastasis in visceral sites (vs. bone; HR = 1.55, 95%CI: 0.94–2.56), the central nervous system (vs. bone; HR = 1.88, 95% CI: 1.10–3.22), and multiple sites (vs. bone; HR = 2.55, 95%CI:1.53–4.25) were prognostic factors of OS whereas multiple metastasis (HR = 2.30, 95% CI: 1.42–3.72) was a predictor of MS. In terms of DRFS, there were no differences according to metastasis type or solid organ.

Conclusion
TNBC patients with multiple metastasis and CNS metastasis have an increased risk of death compared to those with bone metastasis in terms of OS and MS.

Published: February 2024

Purpose
The study’s objective was to determine the optimal window for anterior cruciate ligament (ACL) reconstruction with respect to quadriceps atrophies and clinical outcome.

Methods
For this retrospective, comparative study, 115 patients aged under 35 were included, who received an ACL reconstruction between 2011 and 2016. They were divided into four groups, depending on the time to surgery, to determine the optimal window for reconstruction: (group 1: ≤21 d, group 2: <21d-56d≥, group 3: >56d-100d≥, group 4: >100d). Follow-up was performed one month postoperatively, after a mean of 4.9 (±5.3) months, and after a mean of 3.5 (±1.4) years. Primary endpoints included quadriceps muscle status, range of motion (ROM), pain, swelling, the International Knee Documentation Committee Subjective Knee Form (IKDC), the Lysholm-Score, the Knee Injury and Osteoarthritis Outcome Score (KOOS), and the Tegner-Activity-Scale (TAS).

Results
Significantly more quadriceps atrophies were observed in group 1 and group 4, representing reconstructions earlier than 21 and later than 100 days (29% and 41% vs. 9%; p = 0.032). The measurements of knee extension (p = 0.082) and ROM (p = 0.123) were comparable in all groups. Group 1 showed the least pain (0% vs. 15%; p = 0.285) and swelling (0% vs. 23%; p = 0.077) compared to all other groups one month postoperatively. A comparison of postoperative clinical scores revealed no significant differences, with group 1 exhibiting the lowest TAS levels.

Conclusion
In patients who underwent ACL reconstruction within three weeks or after more than 100 days, a significantly higher incidence of quadriceps atrophy was observed, possibly attributable to the initial inflammatory phase or the delayed reconstruction affecting quadriceps function. However, this impairment may not be observable in elite athletes who undergo reconstruction within hours of the injury.
Factors affecting young doctors’ choice of medical specialty—A qualitative study
Authors: Michalik Beniamin , Kulbat Mateusz , Domagała Alicja 
Published: February 2024

Background
Young doctors’ choice of medical specialty is essential to maintaining a sufficient health workforce and developing a sustainable healthcare system. The choice of specialization is the result of numerous factors, including doctors’ preferences, population needs, and the number of available residency slots. The aim of this article is to explore the factors taken into consideration by young Polish physicians in choosing their future specialty.

Methods
We have conducted 30 structured interviews with randomly selected recent medical school graduates (17 female and 13 male). The study was conducted from December 2022 until February 2023 using online platforms. Data from in-depth interviews were coded using NVivo Release 1.6.1. Then thematic analysis was performed.

Results
Respondents indicated remuneration and career-associated factors as the main determinants, emphasizing that work-life balance, personal motivations, and the flexibility to choose the type of workplace (hospital vs. outpatient clinic) were even more important. Young doctors expect flexibility in working hours and better working conditions in future work, and these factors are important when choosing a medical specialty. Significant difficulties during the selection of medical specialty include limited residency slots in preferred specializations and lack of knowledge concerning the everyday aspects of work in a particular specialty.

Conclusions
Factors and limitations influencing the choice of medical specialty should be taken into account by policymakers to address the shortages of doctors in deficit specialties. Knowledge about doctors’ preferences regarding their medical specialty could support the development of targeted policies to increase the attractiveness of deficit specialties and reduce the uneven distribution of medical staff.

Published: February 2024

Abstract: Introduction: Research into the first phase of the COVID-19 lockdown in Italy showed an association with an increased susceptibility to adverse mental health (MH) in the general population. We investigated in the same population the correlations between the various demographic, socioeconomic, biological/clinical history and psychological dimensions and MH in the second,“opening-up”, phase of the lockdown. Methods: An anonymous online survey collected data from 26 May to 4 July 2020 on demographic, socioeconomic, perceived risk, general health and quality of life appraisals, worry, interference in life, life satisfaction, perceived happiness and MH by using Mental Health Inventory-5 (MHI-5). Results: Of the 300 participants, only 195 responded to MH questions. Older age was positively associated with better MH (r=.15), as was education (r=.19). A negative correlation with MH, with medium-high effect size, was found with quality of life (r=.40) and health (r=.34) appraisals, and the factors “worry about sustenance” (r=.23) and “interference with life” (r=.32). A positive correlation, with strong effect size, was found between MH and life satisfaction (r=.53) and perception of happiness (r=.64). Discussion: During phase two of the lockdown, rather the real impact of COVID-19 restrictions on employment or economic resources, it was worry about finances that was associated with worse MH. Mental distress was associated with the loss of some positive psychological factors. From a homeostatic and biopsychosocial perspective of MH, life satisfaction and perceivedhappiness represent important mental resources for counteracting the effects of lockdown on MH.

Design and investigation of filterless sixtuple RoF upconversion system with improved sideband to carrier suppression ratio using MZM extinction ratio variance
Authors: Kumar Ajay , Singla Shelly , Kedia Deepak 
Published: February 2024

Abstract
In this work, millimeter wave generation of sixtuple frequency scheme using dual parallel Mach–Zehnder modulator configuration has been investigated. The proposed scheme is mathematically analyzed and its performance is evaluated using software optisystem v.18. The vital parameters of both Mach–Zehnder modulator and phase of radio frequency local oscillator are properly adjusted for upconversion of 10 GHz radio frequency drive signal into 60 GHz mm wave. The impact of Mach–Zehnder modulator extinction ratio on radio frequency sideband suppression ratio, optical sideband suppression ratio and third sideband to carrier suppression ratio, is evaluated. An improved 63 dB third sideband to carrier suppression ratio is achieved at increased extinction ratio of Mach–Zehnder modulator. Impact of bias point drift and electrical phase shift on sideband suppression ratios are evaluated. Further, millimeter wave signal of 6–60 GHz tunability is realized by applying radio frequency local oscillator signal from 1 to 10 GHz.
