Authors: Guney Betul , Uzun Erdal 
Published: November 2021

Background Orthopedists prefer imaging studies for the diagnosis, treatment, and follow-up of patients. Purpose To determine the effect of orthopedists’ characteristics, including subspecialty, age, education, and professional experience, in collaboration with radiologists and the usefulness of radiology reports for orthopedists in diagnosis and patient management. Material and Methods Questionnaires, consisting of 21 questions investigating the orthopedists’ characteristics, their behavior with radiology reports, their thoughts on communication, and collaboration with radiologists, were distributed to 205 orthopedists. Descriptive analysis was performed, and the effects of orthopedist characteristics on the outcomes was evaluated. Results In total, 161 out of 205 enrolled participants were included in the analysis. A total of 156 (96.9%) participants stated that they reviewed at least one official radiology report, with MRI receiving the highest rate (92.4%). The main reason provided for not reviewing the radiology reports and requests regarding changes to radiology report formats seemed to be mostly related to time pressure. Despite a significant portion of the participants stating that clinical and surgical findings were inconsistent with radiology reports, less than half were inclined to contact the radiologist most of the time or always. Increasing age ( P = 0.005), experience ( P = 0.016), and university hospital specialization ( P = 0.007) increased the tendency to form multidisciplinary team meetings. Communication with radiologists increased with age ( P < 0.001), while more experience reduced the impact of radiology reports on decision-making ( P = 0.035). Conclusion Increasing cooperation between orthopedists and radiologists will make a significant contribution to decision-making and treatment processes. Orthopedists’ characteristics are influential factors in establishing this communication.

Objective To determine whether heart rate variability (HRV; a physiological measure of acute stress) is associated with persistent psychological distress among family members of adult intensive care unit (ICU) patients. Methods This prospective study investigated family members of patients admitted to a study ICU. Participants’ variability in heart rate tracings were measured by low frequency (LF)/high frequency (HF) ratio and detrended fluctuation analysis (DFA). Questionnaires were completed 3 months after enrollment to ascertain outcome rates of anxiety, depression, and post-traumatic stress disorder (PTSD). Results Ninety-nine participants were enrolled (median LF/HF ratio, 0.92 [interquartile range, 0.64–1.38]). Of 92 participants who completed the 3-month follow-up, 29 (32%) had persistent anxiety. Logistic regression showed that LF/HF ratio (odds ratio [OR] 0.85, 95% confidence interval [CI] 0.43, 1.53) was not associated with 3-month outcomes. In an exploratory analysis, DFA α (OR 0.93, 95% CI 0.87, 0.99), α1 (OR 0.97, 95% CI 0.94, 0.99), and α2 (OR 0.94, 95% CI 0.88, 0.99) scaling components were associated with PTSD development. Conclusion Almost one-third of family members experienced anxiety at three months after enrollment. HRV, measured by LF/HF ratio, was not a predictor of psychologic distress, however, exploratory analyses indicated that DFA may be associated with PTSD outcomes.

Objective The objective of this study was to evaluate the potential impact of irreversible damage accrual in women with systemic lupus erythematosus (SLE) and adverse maternal and/or fetal/neonatal outcomes. Methods Retrospective cohort study with SLE pregnant patients was carried out from January 2011 to January 2020 at the Hospital University Pedro Ernesto (HUPE) of the State University of Rio de Janeiro, Brazil. Irreversible damage was defined according to SLICC/ACR damage index (SDI). The association of SDI on pregnancy outcomes was established by univariate and multivariate regression models and included demographic and clinical variables. Results This study included data from 260 patients in their first pregnancies after SLE diagnosis, with a quarter of them (67/260) scoring one or more points on SDI at the beginning of prenatal care. These patients presented more frequently adverse maternal events, namely, disease activity during pregnancy ( p = 0.004) and puerperium ( p = 0.001), active lupus nephritis ( p = 0.04), and hospitalizations ( p = 0.004), than those with no SDI score. Similarly, the risks of adverse fetal and neonatal outcomes were also higher among the patients with SDI ≥ 1 (59.7% vs 38.3% p = 0.001) even after controlling data for disease activity (SLEPDAI > 4). Patients with SDI ≥ 1 presented more frequently preterm deliveries (46.3% vs 31.6%; p = 0.01), small for gestational age infants (28.3% vs 18.1%; p = 0.04), and neonatal intensive care unit admission (26.9% vs 1.5%; p < 0.001). The multivariate analyses showed that SDI ≥ 1 is an independent risk factor for hospitalization due to obstetric complications ( p = 0.0008) and preterm delivery ( p = 0.009). Conclusion Pregnant SLE patients who present irreversible damage accrual may have higher risk of maternal and fetal adverse outcomes, independently of disease activity. These results should be validated in further prospective studies.

Purpose There is no widely accepted treatment for persistent/chronic central serous chorioretinopathy. The present study aimed to evaluate the efficacy, safety, and factors associated to treatment response to navigated micropulse laser in chorioretinopathy. Methods Retrospective observational case series including consecutive patients presenting with symptomatic persistent and chronic chorioretinopathy. All patients were treated with 5% navigated micropulse laser with the Navilas system (Navilas®, OD-OS GmBH, Teltwo, Germany), by overlying fluorescein angiography, indocyanine green angiography and/or spectral domain-optical coherence tomography images of visible leaking points and/or choroidal hyperpermeability/subretinal fluid to plan the laser treatment. Results Thirty-nine eyes of 36 consecutive patients (29 men and 7 women, with a mean age of 51.87 years) were included. Logarithm of the minimum angle of resolution (LogMar) best-corrected visual acuity increased from 0.39 ± 0.24 at baseline to 0.24 ± 0.22 at 3 months ( p < 0.0001) and to 0.20 ± 0.07 at 6 months ( p < 0.0001). Subretinal fluid decreased from 166.82 ± 111.11 micron at baseline to 52.33 ± 78.97 micron ( p < 0.0001) at 3 months and 34.12 ± 67.56 micron at 6 months ( p < 0.0001). The presence of a hot spot on fluorescein angiography and a focal choroidal hyperpermeability on indocyanine green angiography, but not the duration of symptoms correlated significantly with the resolution of subretinal fluid at month 3 ( p = 0.023 and p  = 0.001). Conclusion Navigated micropulse laser laser treatment was found to be effective and safe for the treatment of chorioretinopathy, with significant improvement in visual and anatomical outcomes, unaccompanied by any adverse event at 3 and 6 months follow-up. Factors associated to subretinal fluid resolution may allow a better selection of likely responders to navigated micropulse laser treatment.
Combination of musculoskeletal and wear models to investigate the effect of daily living activities on wear of hip prostheses

Published: November 2021

Abstract Numerical wear predictions are gaining increasing interest in many engineering applications, as they allow to simulate complex operative conditions not easily replicable in the laboratory. As far as hip prostheses are concerned, most of the wear models in the literature are based on the simulation of gait (recommended also in experimental wear tests), since gait is considered the most frequent and important motor task to recover after arthroplasty. However, since joint prostheses have been increasingly implanted in younger people, high loads and potentially severe conditions, e.g. due to sporting activities, should also be considered for a more reliable wear assessment of these implants. In this study, we propose a profitable combination of musculoskeletal and analytical wear modelling for the prediction of wear caused by common daily activities in metal-on-plastic hip arthroplasties. Several motion analysis data available in the literature (walking, fast walking, lunge, squat, stair negotiation) were selected and the effects of such motor tasks on prosthesis wear were investigated, both separately and in combination. Additionally, for comparative purposes, wear prediction for simplified gait conditions prescribed by the ISO 14242 standard, were also considered. Results suggest that this latter case produces lower wear depth and volume with respect to a relatively demanding combination of the selected daily activities. The preliminary results of the present study represent a first step towards the auspicious goal of validating the proposed procedure for in silico trials of hip arthroplasties.

Published: November 2021

Objectives Through-knee amputation is an umbrella term for several different surgical techniques, which may affect clinical and functional outcomes. This makes it hard to evaluate the benefits and need for a through-knee amputation approach. This article seeks to (1) determine the number of through-knee amputation performed compared with other major lower limb amputations in England over the past decade; (2) identify the theoretical concepts behind through-knee amputation surgical approaches and their potential effect on functional and clinical outcomes and (3) provide a platform for discussion and research on through-knee amputation and surgical outcomes. Methods National Health Service Hospital Episodes Statistics were used to obtain recent numbers of major lower limb amputations in England. EMBASE and MEDLINE were searched using a systematic approach with predefined criteria for relevant literature on through-knee amputation surgery. Results In the past decade, 4.6% of major lower limb amputations in England were through-knee amputations. Twenty-six articles presenting through-knee amputation surgical techniques met our criteria. These articles detailed three through-knee amputation surgical techniques: the classical approach, which keeps the femur intact and retains the patella; the Mazet technique, which shaves the femoral condyles into a box shape and the Gritti-Stokes technique, which divides the femur proximal to the level of the condyles and attaches the patella at the distal cut femur. Conclusions Through-knee amputation has persisted as a surgical approach over the past decade, with three core approaches identified. Studies reporting clinical, functional and biomechanical outcomes of through-knee amputation frequently fail to distinguish between the three distinct and differing approaches, making direct comparisons difficult. Future studies that compare through-knee amputation approaches to one another and to other amputation levels are needed.

Objective: Maternal near-miss refers to a woman who nearly died but survived complications in pregnancy, childbirth, or within 42 days of termination of pregnancy. The study of maternal near-miss has become essential for improving the quality of obstetric care. The objective of this study was to identify the determinants of maternal near-miss among women admitted to major private hospitals in eastern Ethiopia. Method: An unmatched nested case–control study was conducted in major private hospitals in eastern Ethiopia from 5 March to 31 March 2020. Cases were women who fulfilled the sub-Saharan African maternal near-miss criteria and those admitted to the same hospitals but discharged without any complications under the sub-Saharan African maternal near-miss tool were controls. For each case, three corresponding women were randomly selected as controls. Factors associated with maternal near-misses were analyzed using binary and multiple logistic regressions with an adjusted odds ratio along with a 95% confidence interval. Finally, p-value < 0.05 was considered as a cut-off point for the significant association. Results: A total of 432 women (108 cases and 324 controls) participated in the study. History of prior cesarean section (AOR = 4.33; 95% CI = 2.36–7.94), anemia in index pregnancy (AOR = 4.38; 95% CI = 2.43–7.91), being ⩾ 35 years of age (AOR = 2.94; 95% CI = 1.37–6.24), not attending antenatal care (AOR = 3.11; 95% CI = 1.43–6.78), and history of chronic medical disorders (AOR = 2.18; 95% CI = 1.03–4.59) were independently associated with maternal near-miss. Conclusion: Maternal age ⩾ 35 years, had no antenatal care, had prior cesarean section, being anemic in index pregnancy, and have history of chronic medical disorders were the determinants of maternal near-miss. Improving maternal near-misses requires strengthening antenatal care (including supplementation of iron and folic acid to reduce anemia) and prioritizing women with a history of chronic medical illnesses. Interventions for preventing primary cesarean sections are crucial in this era of the cesarean epidemic to minimize its effect on maternal near-miss.

Published: November 2021

Summary Systemic lupus erythematosus (SLE) usually affects young females and its presentation with haemorrhage is unusual. Intracerebral bleed (ICB) has been described in a few case reports, but massive haematuria has not been reported in the literature so far. Here, we present a case of a 56 year-old-lady who presented with expanding lobar bleed and massive haematuria as the first presentation of SLE secondary to vasculitis. Lupus vasculitis usually presents with thrombosis-related complications and although bleeding in this context is rare, it can lead to catastrophic consequences. Hence, vasculitis-related bleeding should be taken under consideration in a challenging situation like ours.
Radiofrequency Energy-Assisted Wire Atrial Septostomy to Easily Create a Large Atrial Septal Defect
Authors: Nishibata Masahiro , Kitano Masataka , Sato Seiich 
Published: November 2021

Wire atrial septostomy, a new transcatheter technique, combines 2 atrial septal defects (ASDs) into a large one in a thickened atrial septum. Although the thin-wire-looped atrial septum between ASDs needs to be pulled deeply into a hard catheter to tear the septum, this action might harm the surrounding cardiac structures. We utilized radiofrequency wire energy to facilitate the tearing of the septum, making the procedure easier and safer. This technical article presents the modified procedure in detail; the procedure was performed in a 6-month-old boy with double outlet right ventricle and intact ventricular septum. Mini-abstract This technical article describes modified wire atrial septostomy for thickened atrial septum in detail. Radiofrequency energy facilitated a thin wire-loop in tearing the septum between 2 atrial septal defects to combine the defects into a large one. We believe that this transcatheter procedure is easier and safer than the original one not using a radiofrequency wire energy.

Background Progressive right heart chambers dilatation is frequent in the adult congenital heart disease (ACHD) population. We evaluated the immediate and mid-term response of right heart chambers to surgery performed in adulthood for lesions associated with right heart chambers enlargement. Methods Thirty-six adult patients with lesions associated with right heart chambers enlargement submitted to surgery were studied . We collected echocardiographic data of right ventricle (RV) mid-diameter, right atrial volume indexed, RV systolic pressure, and tricuspid annular plane systolic excursion (TAPSE) prior to surgery (T0), at 2 to 5 days (T1), and 3 to 6 months (T2) after surgery. Results At T1, we observed a significant decrease of RV mid-diameter (47.2 ± 8.4 vs. 39.6 ± 7.4 mm, P < .001), right atrial volume indexed (45.6 ± 26.6 vs. 27.2 ± 11 ml/m2, P < .001), and RV systolic pressure (39 ± 14.8 vs. 32.8 ± 11.3 mm Hg, P = .03). At T2, a further significant deviation in the rate of RV diameter (39.6 ± 7.4 vs. 34.5 ± 5.1 mm, P < .001), in RV systolic pressure (32.8 ± 11.3 vs. 25.3 ± 5 mm Hg, P = .03) and TAPSE (13.9 ± 3.2 vs. 15.8 ± 2.6 mm, P < .001) was observed. Conclusions Positive right heart chambers remodeling occurs as early as in the immediate post-operative period in most ACHD patients operated for lesions associated with right heart chambers enlargement.

Objective We reviewed our center's prenatal detection and surgical experience with high-risk, 2-ventricle patients, with complex congenital heart disease that underwent stage-1 hybrid palliation. Methods We retrospectively identified those born between March 2008 and March 2021 with 2-ventricle hearts, complex congenital cardiovascular malformations, and ductal-dependent systemic circulation that underwent stage-1 hybrid palliation consisting of surgical bilateral pulmonary artery banding and interventional catheterization placed ductus arteriosus stents. Results We identified 30 patients. Of the 30, 19 (63%) were male. For the 30, median gestational age was 35 weeks (29-39 weeks), and median birth weight was 2.2 kg (0.6-4.5 kg). Of the 30, 1 was transferred from an adjacent state, and 29 were born in Nevada. Of the 29 born in Nevada, overall statewide prenatal detection was 18 of 29 (62%); however, for 2008 to 2011 the prenatal detection rate was 3 of 10 (30%) and 15 of 19 (79%) for 2012 to 2021, P = .03. For the last 5 years, prenatal detection for Nevada-born patients was 8 of 8 (100%). Two full-term newborns, without a prenatal diagnosis, presented postnatally in extremis. For the 30 patients, there were 0 stage-1 hybrid palliation mortalities, 1 subsequent repair mortality, and 3 late nonsurgical deaths. Conclusions Stage-1 hybrid palliation may result in excellent surgical outcomes for high-risk, 2-ventricle patients. Additionally, high rates of population-wide prenatal detection are possible for high-risk congenital heart disease, allowing prenatal planning and possibly reducing postnatal extremis presentations.

Background Hip fractures are well researched in orthogeriatric literature. Equivalent investigations for fragility-associated periprosthetic and periosteosynthetic femoral, ankle joint, pelvic ring, and rib fractures are still rare. The purpose of this study was to evaluate mortality, functional outcome, and socioeconomic parameters associated to the upper-mentioned fragility fractures prospectively in a 2-year follow-up. Methods Over the course of a year, all periprosthetic and periosteosynthetic femoral fractures (PPFF), ankle joint fractures (AJ), pelvic ring fractures (PR), and rib fractures (RF), that were treated on a co-managed orthogeriatric ward, were assessed. Parker Mobility Score (PMS), Barthel Index (BI), place of residence, and care level were recorded. After 2 years, patients and/or relatives were contacted by mailed questionnaires or phone calls in order to calculate mortality and reevaluate the mentioned parameters. Results Follow-up rate was 77.7%, assessing 87 patients overall. The relative mortality risk was significantly increased for PR (2.9 (95% CI: 1.5–5.4)) and PPFF (3.5 (95% CI: 1.2–5.8)) but not for RF (1.5 (95% CI: 0.4–2.6)) and AJ (2.0 (95% CI: 0.0–4.0)). Every fracture group except AJ showed significantly higher BI on average at follow-up. PMS was, respectively, reduced on average for PR and RF insignificantly, but significantly for PPFF and AJ in comparison to pre-hospital values. 10.0–27.3% (each group) of patients had to leave their homes permanently; care levels were raised in 30.0–61.5% of cases. Discussion This investigation provides a perspective for further larger examinations. PR and PPFF correlate with significant increased mortality risk. Patients suffering from PPFF, PR, and RF were able to significantly recover in their activities of daily living. AJ and PPFF conclude in significant reduction of PMS after 2 years. Conclusion Any fragility fracture has its impact on mortality, function, and socioeconomic aspects and shall not be underestimated. Despite some fractures not being the most common, they are still present in daily practice.
