Abstract
OBJECTIVE The femoral tunnel position is crucial to anatomic single-bundle anterior cruciate ligament (ACL) reconstruction, but the ideal femoral footprint position are mostly based on small-sized cadaveric studies and elderly patients with a single ethnic background. This study aimed to identify potential race- or gender-specific differences in the ACL femoral footprint location and ACL orientation, determine the correlation between the ACL orientation and the femoral footprint location. METHODS Magnetic resonance images (MRIs) of 90 Caucasian participants and 90 matched Chinese subjects were used for reconstruction of three-dimensional (3D) femur and tibial models. ACL footprints were sketched by several experienced orthopedic surgeons on the MRI photographs. The anatomical coordinate system was applied to reflect the ACL footprint location and orientation of scanned samples. The femoral ACL footprint locations were represented by their distance from the origin in the anteroposterior (A/P) and distal-proximal (D/P) directions. The orientation of the ACL was described with the sagittal, coronal and transverse deviation angles. The ACL orientation and femoral footprint position were compared by the two-sided t-test. Multiple regression analysis was used to study the correlation between the orientation and femoral footprint position. RESULTS The average femur footprint A/P position was -6.6 ± 1.6 mm in the Chinese group and -5.1 ± 2.3 mm in the Caucasian group, (p < 0.001). The average femur footprint D/P position was -2.8 ± 2.4 mm in Chinese and - 3.9 ± 2.0 mm in Caucasians, (p = 0.001). The Chinese group had a mean difference of a 1.5 mm (6.1%) more posterior and 1.1 mm (5.3%) more proximal in the position from the flexion-extension axis (FEA). And the males have a sagittal plane elevation about 4-5° higher than females in both racial groups. Furthermore, for every 1% (0.40 mm) increase in A/P and D/P values, the sagittal angle decreased by about 0.12° and 0.24°, respectively; the coronal angle decreased by about 0.10° and 0.30°, respectively. For every 1% (0.40 mm) increase in D/P value, the transverse angle increased by about 0.14°. CONCLUSION The significant race- and gender-specific differences in the femoral footprint and orientation of the ACL should be taken in consideration during anatomic single-bundle ACL reconstruction. Furthermore, the quantitative relationship between the ACL orientation and the footprint location might provide some reference for surgeons to develop a surgical strategy in ACL single-bundle reconstruction and revision.

Abstract
OBJECTIVE Understanding the morphology of the distal femur is essential for improving bone-implant match in total knee arthroplasty (TKA) and understanding the mechanisms behind knee kinematics. However, little is known about the asymmetry of the posterior condyles. Thus, this study aimed to thoroughly investigate asymmetries in sizes and shapes between the medial and lateral posterior condyles before and after femoral resections during TKA in osteoarthritic (OA) knees. METHODS Three-dimensional femoral models of 74 OA knees were constructed using computed tomography images. The morphologic measurements of the posterior condyle pre- and post-simulated osteotomy for TKA included the radii of the posterior condyles fitted to a circle on the sagittal and axial planes of the femoral coordinate system, the inclination angle of the articular surface and resected surface, and the width and height of the resected surface. Differences in the data were assessed using Student's t-test, and correlations were evaluated using the Pearson product-moment correlation. RESULTS The radii of the medial posterior condyles fitted to the circle were, on average, 6 mm larger than those of the lateral condyles on the axial plane (p < 0.001) and 0.7 mm smaller than those of the lateral condyles on the sagittal plane (p = 0.046). The inclination angles of the medial and lateral posterior condyles on the axial plane were significantly different with both pre-simulated and post-simulated osteotomy, respectively (both p < 0.001). The resected plane of the lateral posterior condyles displaced opposite inclination directions between the distal and proximal portions. Neither heights or widths of the medial posterior condyles were significantly different from those of their lateral counterparts (both p > 0.107). CONCLUSIONS This study found asymmetrical inclination of the resected surface and coronal radii between the medial and lateral posterior condyles, which may relate to the posterolateral overhang of the lateral condyle after TKA and the progression of the knee OA. These findings provides valuable morphological information and may help improve the implant designs for TKA.

Abstract
Exposure to less-hygienic conditions during early childhood has been associated with stimulation and development of the immune system. A recent study indicated that exposure of piglets to soil-borne microbes during lactation was related with modulation of gut microbiota and immune function. To identify the potential molecular mechanisms and pathways impacted by early-life topsoil exposure, we analyzed the messenger RNA (mRNA) and micro-RNA (miRNA) expression in peripheral blood mononuclear cells (PBMCs) from these piglets. Total RNA was extracted from the PBMCs of piglets exposed to topsoil only from d 4–d 21 of life (mRNA n = 6; miRNA n = 5) or unexposed control pigs (mRNA n = 6; miRNA n = 8) at 11, 20, and 56 days of age. Small RNA and mRNA were sequenced with 50-bp single-end reads using Illumina chemistry. Sequence data were quality checked with FASTQC software and aligned to the Sscrofa 11.1 genome with the STAR aligner for mRNA and mirDeep2 for miRNA. Differential expression (DE) analysis was performed using PROC Glimmix of SAS to evaluate changes in expression due to topsoil exposure over time with genes declared DE at a false discovery rate (FDR) of q < 0.10. A total of 138 mRNA and 21 miRNAs were identified as DE for the treatment by age interaction. Ontology enrichment analysis of DE mRNA revealed Gene ontology (GO) terms directly involved in the connection between T-cell and antigen-presenting cells that are associated with T-cell activation. Key regulatory genes identified include PTPRJ, ITGB3, TRBV30, CD3D, mir-143, mir-29, and mir-148a. While these results require validation, this study provides data supporting the hypothesis that less-hygienic environments during early life may contribute to the development of the immune system.

Abstract
Abstract
Introduction/Objective
Acute myeloid leukemia (AML) patients often require transfusion support during induction chemotherapy. Platelet transfusion refractoriness (PTR) may develop due to HLA alloimmunization. Management of immune-refractory patients with HLA-compatible platelet transfusions is labor intensive and associated with increased costs. The purpose of this study is to evaluate the efficacy of HLA-compatible platelet units in AML patients.
Methods
Newly diagnosed AML patients undergoing induction chemotherapy in our institute between 2015 and 2018 were identified. Platelet counts and platelet transfusion data from initiation of chemotherapy until platelet recovery (> 20K/µL and increased consistently) were extracted. A 24-hour posttransfusion corrected count increment (CCI) was calculated to evaluate the efficacy of each platelet transfusion. PTR was declared if a patient had a 24-hour CCI < 4K following two consecutive transfusions. Student’s t-test was used for statistical analysis. Results were presented as mean ± SE, * if p < 0.05.
Results
We identified 39 patients with newly diagnosed AML. PTR developed in 22/39 (56%) patients during induction chemotherapy. The average CCI was higher among those without PTR compared to those with PTR (8,408 ± 585 vs. 2,923 ± 360*), and overall platelet transfusion burden (in number of units) was lower (7.29 ± 1.0 vs. 18.55 ± 1.71*). HLA antibodies were identified in 3/22 (14%) PTR patients, as 6/22 (27%) were tested. The average CCI during HLA matched transfusions for these 3 patients was higher than that with random units (2,059 ± 149 vs. -126 ± 306*). Compared to HLA-negative PTR patients receiving random units, the average CCI for HLA-compatible transfusions was still lower, though not significantly (2,059 ± 149 vs. 3,099 ± 390, p = 0.33), while the number of HLA- compatible units transfused was significantly higher (31.0 ± 3.0 vs. 16.6 ± 1.45*).
Conclusion
In a cohort of newly diagnosed AML patients undergoing induction chemotherapy whose PTR was associated with detectable HLA antibodies, transfusion support with HLA-matched products did not lead to reduced overall platelet transfusion rates and CCI remains in the refractory range. This suggests that use of HLA matched platelets among newly diagnosed AML patients with PTR, even in the setting of detectable HLA antibodies, does not appear to result in reduced overall product utilization.

Abstract
In order to understand the pathological processes of retinal diseases, experimental models are necessary. Cobalt, as part of the vitamin B12 complex, is important for neuronal integrity. However, it is known that high quantities of cobalt induce cytotoxic mechanisms via hypoxia mimicry. Therefore, we tested the degenerative effect of cobalt chloride (CoCl2) on neurons and microglia in a porcine retina organ culture model. Organotypic cultures of porcine retinas were cultured and treated with different concentrations of CoCl2 (0, 100, 300 and 500 μM) for 48 h. After four and eight days, CoCl2 induced a strong degeneration of the porcine retina, starting at 300 μM. A loss of retinal ganglion cells (RGCs, Brn-3a), amacrine cells (calretinin) and bipolar cells (PKCα) was observed. Additionally, a high expression of hypoxia induced factor-1a (HIF-1a) and heat shock protein 70 (HSP70) was noted at both points in time. Also, the Caspase 3 protein was activated and P21 expression was induced. However, only at day four, the Bax/Bcl-2 ratio was increased. The effect of CoCl2 was not restricted to neurons. CoCl2 concentrations reduced the microglia amount (Iba1) and activity (Iba1 + Fcγ-Receptor) at both points in time. These damaging effects on microglia were surprising, since CoCl2 causes hypoxia and a pro-inflammatory environment. However, high concentrations of CoCl2 also seem to be toxic to these cells. Similar degenerative mechanisms as in comparison to retinal ischemia animal models were observed. In summary, an effective and reproducible hypoxia-mimicking organotypic model for retinal degeneration was established, which is easy to handle and ready for drug studies.

Abstract
BACKGROUND AND PURPOSE A minority of intracranial dural arteriovenous fistulas progress with time. We sought to determine features that predict progression and define outcomes of patients with progressive dural arteriovenous fistulas. MATERIALS AND METHODS We performed a retrospective imaging and clinical record review of patients with intracranial dural arteriovenous fistula evaluated at our hospital. RESULTS Of 579 patients with intracranial dural arteriovenous fistulas, 545 had 1 fistula (mean age, 45 ± 23 years) and 34 (5.9%) had enlarging, de novo, multiple, or recurrent fistulas (mean age, 53 ± 20 years; P = .11). Among these 34 patients, 19 had progressive dural arteriovenous fistulas with de novo fistulas or fistula enlargement with time (mean age, 36 ± 25 years; progressive group) and 15 had multiple or recurrent but nonprogressive fistulas (mean age, 57 ± 13 years; P = .0059, nonprogressive group). Whereas all 6 children had fistula progression, only 13/28 adults (P = .020) progressed. Angioarchitectural correlates to chronically elevated intracranial venous pressures, including venous sinus dilation (41% versus 7%, P = .045) and pseudophlebitic cortical venous pattern (P = .048), were more common in patients with progressive disease than in those without progression. Patients with progressive disease received more treatments than those without progression (median, 5 versus 3; P = .0068), but as a group, they did not demonstrate worse clinical outcomes (median mRS, 1 and 1; P = .39). However, 3 young patients died from intracranial venous hypertension and intracranial hemorrhage related to progression of their fistulas despite extensive endovascular, surgical, and radiosurgical treatments. CONCLUSIONS Few patients with dural arteriovenous fistulas follow an aggressive, progressive clinical course despite treatment. Younger age at initial presentation and angioarchitectural correlates to venous hypertension may help identify these patients prospectively.

Abstract
A field-deployable mid-infrared quantum cascade laser-based spectrometer was designed and developed for measurements of H2(16)O and H2(18)O at 7.12 μm. H2(16)O and H2(18)O absorption features at 1390.52 cm(-1) and 1389.91 cm(-1), respectively, accessible within current tuning range of the laser, were targeted. The target lines were carefully selected to assure similar absorption levels and similar temperature sensitivities of the line strength due to comparable lower state energies. A real-time spectral fitting algorithm was implemented for isotopic concentration retrieval. Detection limits for H2(16)O and H2(18)O of 2.2 ppm and 7.0 ppb, respectively, were achieved at a dew point of 14 °C (volume mixing ratio of 15,766 ppm) in 1 s integration time, which resulted in a δ(18)O isotopic ratio measurement precision of 0.25‰. The ultimate minimum detection limits obtained after 160 s integration time for H2(16)O and H2(18)O, and δ(18)O measurements were 0.6 ppm, 1.7 ppb, and 0.05‰, respectively.

Abstract
Three groups of gestating gilts and sows (Exp. 1; n = 98) were used to determine the effects of Pichia guilliermondii (Pg), a whole yeast product (CitriStim, ADM Alliance Nutrition), on dam and litter immune parameters. At breeding, gilts and sows were allotted to 1 of 3 treatments maintained through lactation: sow control (SC) diet or SC supplemented with 0.1 (S1) or 0.2% (S2) Pg. Pigs from groups 1 (Exp. 2) and 2 (Exp. 3) were weaned (21 d) and allotted in a 3 (SC, S1, or S2) × 2 [nursery with Pg (NPg) or without Pg (NC)] factorial arrangement in a randomized complete block design. In Exp. 2 blood samples were collected on days 5 and 28 postweaning for analysis. In Exp. 3, 36 pigs were individually penned and challenged with lipopolysaccharide (25 μg/kg BW intramuscular; 0 h). Individual BW, ADFI, and rectal temperature (RT) were collected at -48, -24, 0, 24, and 48 h and blood samples were collected at 0, 5, and 24 h for analysis. In Exp. 1, total neutrophil count (NEU) and neutrophil:lymphocyte ratio (NLR) were greater on day 110 of gestation (P < 0.05) in S1 than SC. At weaning there was a liner increase (P < 0.05) in NEU, NLR, and percentage of total leukocytes (PTL) that were NEU as level of Pg increased in sow diets. In Exp. 2, pigs from S1 had increased (P < 0.05) overall IgG than SC. The PTL that were eosinophils was greater in pigs from S2 fed NPg on day 5 than NC (P < 0.05) and increased in all pigs from S2 on day 28 (sow linear, P < 0.1). On day 28, total leukocytes and eosinophils were increased in pigs from SC [quadratic response (Q), P < 0.05]. In Exp. 3, a linear increase (P < 0.05) in ADFI was observed at -24 to 0 h, -48 to 0 h, and 24 to 48 h as the level of Pg increased in sow diets. There was a linear increase in RT at -48, -24, 0, and 5 h with increasing Pg inclusion in sow diets (P < 0.05). However, RT decreased more from 5 to 24 h in pigs from sows receiving Pg. The number of monocytes and PTL that were monocytes were higher in S2 compared to SC and S1 (P < 0.05). Also, NEU were reduced at 5 h in S1 (P < 0.05), NLR was lower in S2 at 0 h and S1 at 5 h, IL-1β concentration was greater in SC at 0 h and S1 at 5 h, and IL-6 concentration was greater in S2 at 0 h and S1 at 5 h (P < 0.05). Furthermore, blood urea N (BUN) was higher in NC at 0 and 5 h than NPg (P < 0.05). In conclusion, Pg appears to impact immune response criteria of sows and weaned pigs.

Abstract
Stiff-person syndrome (SPS) is an uncommon yet under-diagnosed, neuromuscular disorder characterised by progressive muscle rigidity with superimposed painful muscle spasms triggered by tactile, auditory or emotional stimulation. We describe the world's first case report of typical SPS in a patient with previously excised thymoma and treated non-Hodgkin lymphoma. This is of relevance because of the increasingly elucidated autoimmune aetiology of SPS.

Abstract
In this work, a 10-wavelength, polarization-multiplexed, monolithically integrated InP coherent QPSK transmitter PIC is demonstrated to operate at 112 Gb/sec per wavelength and total chip superchannel bandwidth of 1.12 Tb/s. This demonstration suggests that increasing data capacity to multi-Tb/s per chip is possible and likely in the future.
