Introduction: Balloon and stent angioplasty of the pulmonary arteries (PAs) are frequently performed following superior cavopulmonary connection (SCPC), not only to normalize the caliber of the affected PA but also in hopes of maximizing downstream growth over time. There are limited data on the impact on subsequent PA growth prior to total cavopulmonary connection (TCPC). Methods: A single-center, retrospective cohort study was performed on children who underwent transcatheter (TC) PA intervention following SCPC between January 1, 2010, and December 31, 2018. Growth of treated and contralateral PAs was measured at the lobar bifurcation (distal branch PA [DBPA]) and in the proximal lower lobe (lower lobe branch [LLB]) on serial angiograms. Growth rate was evaluated using a mixed-effect model clustered by individual patient with an interaction term for treated PA and time to evaluate for differential growth rates between treated and contralateral PAs. Results: Thirty-five patients underwent TC PA intervention following SCPC, at a median of 70 days (interquartile range: 19-297 days) postoperatively. Significant growth was seen at both DBPA and LLB for raw (0.8 mm/year, 95% CI: 0.6-1.0, P < .001 for both) and body surface area (BSA) adjusted measures (8.4mm/m2/year, 95% CI: 5.6-11.2, P < .001; 7.9 mm/m2/year, 95% CI: 5.5-10.2, P < .001). The growth rate of the treated vessel was not significantly different from that of the contralateral vessel at the DBPA or LLB positions for raw ( P = .71, .70) or BSA-adjusted measurements ( P = .86, .64). Conclusion: Transcatheter PA intervention was associated with normal distal PA growth rate relative to the untreated side.

Introduction The effect of surgical vs nonsurgical management on hip fracture mortality of Hispanic-American male veterans has not been rigorously studied. Hence, we examined the mortality and life expectancy effect of nonsurgical vs surgical management after hip fracture in a geriatric Hispanic-American male veterans’ population. Material and Methods This was a retrospective cohort study of Hispanic-American male veterans who were 65 years of age or older and suffered a femoral neck or intertrochanteric fracture from January 2008 to December 2015. Analysis between a surgical cohort (cannulated screw fixation, hemiarthroplasty, total hip arthroplasty, or cephalomedullary nail) and a non-surgical cohort was performed. In-hospital, 30-day, one-year, and two-year mortality were compared between both groups. Results Out of 268 patients with hip fracture, 159 (59.2%) were treated surgically and 109 (40.8%) non-surgically. The overall in-hospital (9.2% vs 1.9%, P = .009), 30-day (17.4% vs 5.0%, P = .002), one-year (48.6% vs 23.3%, P < .001), and two-year (63.3% vs 36.5%, P < .001) mortality rate was found to be higher for the nonoperative group. The average life expectancy of the nonoperative cohort was significantly shorter than those who were managed surgically (216 days vs 260 days, P < .001). Discussion and Conclusion This study shows a higher mortality rate and lower life expectancy in geriatric male patients who were treated nonsurgically in a Veterans Health Affair hospital facility that mostly serves Hispanic-American veterans. Our results provide an expansion to the findings of other geriatric studies on hip fracture with focus in a Hispanic-American veteran male population.
The knee function of the soccer players after ACLR is comparable with non-injured controls: A case-control study

Published: September 2021

Purpose: Many studies report a high primary success rate of ACL reconstruction (ACLR), with an increased risk of decline in knee performance correlating with the time passed since surgery. Only one study has compared male soccer players after ACLR to a matched control group of uninjured players in terms of their return to sport and performance. The purpose of this cross-sectional case-control study was to determine the knee performance between soccer players after ACLR and control group matched by age, sex, and professional experience. Methods: All the male professional soccer players aged 18–36 years at the time of injury, who sustained an ACL tear while playing league soccer in Poland between January 2008 and December 2011 were contacted and compared with age and experience-matched healthy control group selected from professional football players. KOOS, IKDC-2000, Lysholm and SF-36 scales were used for comparison. Results: The average follow-up was 7.9 years (range 6–9 years). The ACL-injured soccer players scored significantly lower in IKDC and Lysholm scores compared with the reference group but still were classified as normal knee function in both scales. In all five dimensions of the KOOS and subscales of SF-36 no apparent differences were noted. In all scales in the study group, no correlation was observed between the player’s age and follow-up time after ACLR. Conclusion: After ACL reconstruction and successful return to professional sport, knee function is as good as uninjured team members in the midterm follow-up. Level of evidence: III
A biomechanical study on the effect of lengthening magnitude on spine off-loading in magnetically controlled growing rod surgery: Implications on lengthening frequency

Published: October 2021

Purpose: To assess whether the magnitude of lengthening in magnetically controlled growing rod (MCGR) surgeries has an immediate or delayed effect on spinal off-loading. Methods: 9 whole porcine spines were instrumented using two standard MCGRs from T9 to L5. Static compression testing using a mechanical testing system (MTS) was performed at three MCGR lengthening stages (0 mm, 2 mm, and 6 mm) in each spine. At each stage, five cycles of compression at 175N with 25 min of relaxation was carried out. Off-loading was derived by comparing the load sustained by the spine with force applied by the MTS to the spine. Micro-CT imaging was subsequently performed. Results: The mean load sustained by the vertebral body before lengthening was 39.69N, and immediately after lengthening was 25.12N and 19.91N at 2 mm and 6 mm lengthening, respectively; decreasing to 10.07N, 8.31N, and 8.17N after 25 minutes of relaxation, at 0 mm, 2 mm, and 6 mm lengthening stages, respectively. There was no significant difference in off-loading between 2 mm and 6 mm lengthening stages, either instantaneously ( p = 0.395) or after viscoelastic relaxation ( p = 0.958). CT images showed fractures/separations at the level of pedicle screws in six spines and in the vertebral body’s growth zone in five spines after 6 mm MCGR lengthening. Conclusion: This study demonstrated MCGRs cause significant off-loading of the spine leading to stress shielding. 6 mm of lengthening caused tissue damage and microfractures in some spines. There was no significant difference in spine off-loading between 2 mm and 6 mm MCGR lengthening, either immediately after lengthening or after viscoelastic relaxation.

Introduction Patients in intensive care units (ICUs) may transition into an end-of-life phase during treatment. Advance care planning (ACP) for this population has not been studied comprehensively, and support for its implementation is insufficient. Objective This study aims to clarify the ACP support needs among critical perioperative patients. Methods In this qualitative descriptive study, semistructured interviews were conducted with patients previously admitted to the ICU. The survey was conducted from September to November 2019. Participants comprised 13 individuals, who were admitted to the ICU for a period of 3 months to 2 years after surgery. Results The average age of the participants was 63.8 years. The average mechanical ventilation duration following surgery was 24.5 h. The interviews focused on the ACP needs from the preoperative period to discharge. About 90% of the patients thought about the possibility of death before surgery and considered giving advance orders (e.g., “I don't want life-sustaining treatment”). The participants discussed inheritance, work-related matters, and household issues with their families but rarely spoke about treatment and care. Although they examined the content of the advance directives, the medical staff was not informed about them. Patients revealed that they wanted to understand the distinction between life-prolonging and life-saving treatments and discuss it with the medical staff, apart from being educated on ACP. Many patients previously admitted to the ICU are unclear about the difference between life-prolonging and life-saving treatments; this is also true for medical staff. Conclusion Patients who had been admitted to the ICU after high-risk surgery thought they needed help with ACP before surgery. Therefore, patients have the right to know about treatment risks; however, medical staff believes that this is difficult to communicate. Thus, medical staff should consider ways to communicate clearly with patients, including discussing the risks associated with surgery.

AbstractChronic nonresolving inflammatory syndrome is a major disease feature in myeloproliferative neoplasms (MPNs). Systemic inflammation promotes the growth of the JAK2-V617F+ hematopoietic stem cell clone and is associated with constitutive symptoms (eg, fever, cachexia, and fatigue). Therefore, it is being discussed whether anti-inflammatory therapy, in addition to the well-established JAK inhibitor therapy, may be beneficial in the control of constitutive symptoms. Moreover, effective control of the inflammatory microenvironment may contribute to prevent transformation into secondary myelofibrosis and acute leukemia. Given the pivotal role of tumor necrosis factor α (TNF-α) in MPN and the distinct roles of TNF-α receptor 1 (TNFR1) and TNFR2 in inflammation, we investigated the therapeutic effects of αTNFR1 and αTNFR2 antibody treatment in MPN-like disease using the JAK2+/VF knock-in mouse model. Peripheral blood counts, bone marrow/spleen histopathology, and inflammatory cytokine levels in serum were investigated. αTNFR2 antibody treatment decreased white blood cells and modulated the serum levels of several cytokines [CXCL2, CXCL5, interleukin-12(p40)], as well as of macrophage colony-stimulating factor, but they lacked efficacy to ameliorate hematocrit and splenomegaly. αTNFR1 antibody treatment resulted in the mild suppression of elevated hematocrit of −10.7% and attenuated splenomegaly (22% reduction in spleen weight). In conclusion, our studies show that TNFR1 and TNFR2 play different roles in the biology of JAK2-V617F–induced disease that may be of relevance in future therapeutic settings.

Abstract
Multiple myeloma, a plasma cell malignancy in the bone marrow, remains largely incurable with currently available therapeutics. In this study, we discovered that the activated leukocyte cell adhesion molecule (ALCAM) interacted with epidermal growth factor receptor (EGFR), and regulated myelomagenesis. ALCAM was a negative regulator of myeloma clonogenicity. ALCAM expression was positively correlated with patients’ survival. ALCAM-knockdown myeloma cells displayed enhanced colony formation in the presence of bone marrow stromal cells (BMSCs). BMSCs supported myeloma colony formation by secreted epidermal growth factor (EGF), which bound with its receptor (EGFR) on myeloma cells and activated Mek/Erk cell signaling, PI3K/Akt cell signaling, and hedgehog pathway. ALCAM could also bind with EGFR, block EGF from binding to EGFR, and abolish EGFR-initiated cell signaling. Hence, our study identifies ALCAM as a novel negative regulator of myeloma pathogenesis.

Abstract
The role of consolidation radiotherapy (RT) for bulky lesions is controversial in patients with advanced-stage Hodgkin lymphoma who achieve complete metabolic response (CMR) after doxorubicin, bleomycin, vinblastine, dacarbazine (ABVD)–based chemotherapy. We present the final results of the Fondazione Italiana Linfomi HD0801 trial, which investigated the potential benefit of RT in that setting. In this phase 3 randomized study, patients with a bulky lesion at baseline (a mass with largest diameter ≥5 cm) who have CMR after 2 and 6 ABVD cycles were randomly assigned 1:1 to RT vs observation (OBS) with a primary endpoint of event-free survival (EFS) at 2 years. The sample size was calculated estimating an EFS improvement for RT of 20% (from 60% to 80%). The secondary end point was progression-free survival (PFS). One hundred sixteen patients met the inclusion criteria and were randomly assigned to RT or OBS. Intention-to-treat (ITT) analysis showed a 2-year EFS of 87.8% vs 85.8% for RT vs OBS (hazard ratio [HR], 1.5; 95% confidence interval [CI], 0.6-3.5; P = .34). At 2 years, ITT-PFS was 91.3% vs 85.8% (HR, 1.2; 95% CI, 0.5-3; P = .7). Patients in CMR randomly assigned to OBS had a good outcome, and the primary end point of a 20% benefit in EFS for RT was not met. However, the sample size was underpowered to detect a benefit of 10% or less, keeping open the question of a potential, more limited role of RT in this setting. This trial was registered at www.clinicaltrials.gov as #NCT00784537.

Abstract
Background
The purpose of this formative study was to assess barriers and facilitators to participation of transgender and gender diverse (TGD) patients in clinical research to solicit specific feedback on perceived acceptability and feasibility of research methods to inform creation of a multisite longitudinal cohort of primary care patients engaged in care at two community health centers.

Method
Between September–November 2018, four focus groups (FGs) were convened at two community health centers in Boston, MA and New York, NY (N = 28 participants across all 4 groups; 11 in Boston and 17 in New York). FG guides asked about patient outreach, acceptability of study methods and measures, and ideas for study retention. FGs were facilitated by TGD study staff, lasted approximately 90 min in duration, were audio recorded, and then transcribed verbatim by a professional transcription service. Thematic analyses were conducted by two independent analysts applying a constant comparison method. Consistency and consensus were achieved across code creation and application aided by Dedoose software.

Results
Participants were a mean age of 33.9 years (SD 12.3; Range 18–66). Participants varied in gender identity with 4 (14.3%) men, 3 (10.7%) women, 8 (28.6%) transgender men, 10 (35.7%) transgender women, and 3 (10.7%) nonbinary. Eight (26.6%) were Latinx, 5 (17.9%) Black, 3 (10.7%) Asian, 3 (10.7%) another race, and 5 (17.9%) multiracial. Motivators and facilitators to participation were: research creating community, research led by TGD staff, compensation, research integrated into healthcare, research applicable to TGD and non-TGD people, and research helping TGD communities. Barriers were: being research/healthcare averse, not identifying as TGD, overlooking questioning individuals, research coming from a ‘cisgender lens”, distrust of how the research will be used, research not being accessible to TGD people, and research being exploitative.

Conclusion
Though similarities emerged between the perspectives of TGD people and research citing perspectives of other underserved populations, there are barriers and facilitators to research which are unique to TGD populations. It is important for TGD people to be involved as collaborators in all aspects of research that concerns them.

Abstract
Background
Physical activity (PA) may play a key role in healthy aging and thus in promoting health-related quality of life (HRQoL). However, longitudinal studies on the association between PA and HRQoL are still scarce and have shown inconsistent results. In this study, we aimed to examine the longitudinal association between frequency of moderate PA and physical and mental HRQoL. Secondly, to assess the association between a 12-month change in frequency of moderate PA and HRQoL.

Methods
A 12-month longitudinal study was conducted in Spain, Greece, Croatia, the Netherlands, and the United Kingdom with 1614 participants (61.0% female; mean age = 79.8; SD = 5.2) included in the analyses. Two categories of the self-reported frequency of moderate PA including 1) ‘regular frequency’ and 2) ‘low frequency’ were classified, and four categories of the change in frequency of moderate PA between baseline and follow-up including 1) ‘continued regular frequency’, 2) ‘decreased frequency’, 3) ‘continued low frequency’ and 4) ‘increased frequency’ were identified. Physical and mental HRQoL were assessed by the 12-Item Short-Form Health Survey (SF-12).

Results
The frequency of moderate PA at baseline was positively associated with HRQoL at follow-up. Participants with a continued regular frequency had the highest HRQoL at baseline and follow-up. Participants who increased the frequency of moderate PA from low to regular had better physical and mental HRQoL at follow-up than themselves at baseline. After controlling for baseline HRQoL and covariates, compared with participants who continued a regular frequency, participants who decreased their frequency had significantly lower physical (B = -4.42; P < .001) and mental (B = -3.95; P < .001) HRQoL at follow-up; participants who continued a low frequency also had significantly lower physical (B = -5.45; P < .001) and mental (B = -4.10; P < .001) HRQoL at follow-up. The follow-up HRQoL of participants who increased their frequency was similar to those who continued a regular frequency.

Conclusions
Maintaining or increasing to a regular frequency of PA are associated with maintaining or improving physical and mental HRQoL. Our findings support the development of health promotion and long-term care strategies to encourage older adults to maintain a regular frequency of PA to promote their HRQoL.

Abstract
Background
Traditionally tricyclic antidepressants (TCAs) have an important place in treatment of major depressive disorder (MDD). Today, often other antidepressant medications are considered as first step in the pharmacological treatment of MDD, mainly because they are associated with less adverse effects, whereby the position of TCAs appears unclear. In this study we aimed to examine the current practice of TCAs in treatment of unipolar MDD.

Methods
A mixed methods approach was applied. First, a selection of leading international and national guidelines was reviewed. Second, actual TCA prescription was examined by analyzing health records of 75 MDD patients treated with the TCAs nortriptyline, clomipramine or imipramine in different centers in the Netherlands. Third, promotors and barriers influencing the choice for TCAs and dosing strategies were explored using semi-structured interviews with 24 Dutch psychiatrists.

Results
Clinical practice guidelines were sometimes indirective and inconsistent with each other. Health records revealed that most patients (71%) attained therapeutic plasma concentrations within two months of TCA use. Patients who achieved therapeutic plasma concentrations reached them on average after 19.6 days (SD 10.9). Both health records and interviews indicated that therapeutic nortriptyline concentrations were attained faster compared to other TCAs. Various factors were identified influencing the choice for TCAs and dosing by psychiatrists.

Conclusions
Guideline recommendations and clinical practice regarding TCA prescription for MDD vary. To increase consistency in clinical practice we recommend development of an up-to-date guideline integrating selection and dosing of TCAs, including the roles of therapeutic drug monitoring and pharmacogenetics. Such a guideline is currently lacking and would contribute to optimal TCA treatment, whereby efficacy and tolerability may be increased.
