Running Biomechanics Before Injury and 1 Year After Anterior Cruciate Ligament Reconstruction in Division I Collegiate Athletes

Background: Preinjury running biomechanics are an ideal comparator for quantifying recovery after anterior cruciate ligament (ACL) reconstruction (ACLR), allowing for assessments within the surgical and nonsurgical limbs. However, availability of preinjury running biomechanics is rare and has been reported in case studies only. Purpose/Hypothesis: The purpose of this study was to determine if running biomechanics return to preinjury levels within the first year after ACLR among collegiate athletes. We hypothesized that (1) surgical knee biomechanics would be significantly reduced shortly after ACLR and would not return to preinjury levels by 12 months and (2) nonsurgical limb mechanics would change significantly from preinjury. Study Design: Cohort study; Level of evidence, 2. Methods: Thirteen Division I collegiate athletes were identified between 2015 and 2020 (6 female; mean ± SD age, 20.7 ± 1.3 years old) who had whole body kinematics and ground-reaction forces recorded during treadmill running (3.7 ± 0.6 m/s) before sustaining an ACL injury. Running analyses were repeated at 4, 6, 8, and 12 months (4M, 6M, 8M, 12M) after ACLR. Linear mixed effects models were used to assess differences in running biomechanics between post-ACLR time points and preinjury within each limb, reported as Tukey-adjusted P values. Results: When compared with preinjury, the surgical limb displayed significant deficits at all postoperative assessments (P values <.01; values reported as least squares mean difference [SE]): peak knee flexion angle (4M, 13.2° [1.4°]; 6M, 9.9° [1.4°]; 8M, 9.8° [1.4°]; 12M, 9.0° [1.5°]), peak knee extensor moment (N·m/kg; 4M, 1.32 [0.13]; 6M, 1.04 [0.13]; 8M, 1.04 [0.13]; 12M, 0.87 [0.15]; 38%-57% deficit), and rate of knee extensor moment (N·m/kg/s; 4M, 22.7 [2.4]; 6M, 17.9 [2.3]; 8M, 17.5 [2.4]; 12M, 16.1 [2.6]; 33%-46% deficit). No changes for these variables from preinjury (P values >.88) were identified in the nonsurgical limb. Conclusion: After ACLR, surgical limb knee running biomechanics were not restored to the preinjury state by 12M, while nonsurgical limb mechanics remained unchanged as compared with preinjury. Collegiate athletes after ACLR demonstrate substantial deficits in running mechanics as compared with preinjury that persist beyond the typical return-to-sport time frame. The nonsurgical knee appears to be a valid reference for recovery of the surgical knee mechanics during running, owing to the lack of change within the nonsurgical limb.
Deep brain stimulation for treatment-refractory obsessive-compulsive disorder should be an accepted therapy in Australia

Deep brain stimulation has shown promise for the treatment of severe, treatment-refractory obsessive-compulsive disorder. With the recent publication of the first Australian, randomised, sham-controlled trial of deep brain stimulation for obsessive-compulsive disorder, there are now four placebo-controlled trials demonstrating the efficacy of this therapy. Together with recent data identifying a biological substrate of effective stimulation that can predict response and that has been successfully reproduced, studies comparing and finding equivalent efficacy among different targets, as well as recent, large, open trials supporting the long-term effectiveness of deep brain stimulation, we argue that this should now be considered an accepted therapy for a select group of patients in the Australasian setting. We call on the Royal Australian and New Zealand College of Psychiatrists to revise their memorandum describing deep brain stimulation for obsessive-compulsive disorder as an ‘experimental’ treatment and recognise that it has proven efficacy. We stress that this should remain a therapy offered only to those with high treatment-refractory illnesses and only at specialised centres where there is an experienced multidisciplinary team involved in work-up, implantation and follow-up and also where frameworks are in place to provide careful clinical governance and ensure appropriate fully informed consent.
In vitro affinity maturation of broader and more-potent variants of the HIV-1–neutralizing antibody CAP256-VRC26.25

Significance Broadly neutralizing antibodies (bNAbs) can prevent new HIV-1 infections, but most are insufficiently broad or potent to protect from the diverse pool of circulating viruses. V2-glycan/apex bNAbs are exceptionally potent, but their breadth is limited. Their neutralizing activity requires tyrosine sulfation, a posttranslational modification that precludes their improvement with phage or yeast display. Here, we demonstrate the utility of a mammalian display approach whereby the heavy- and light-chain loci of a B cell line are CRISPR edited to encode the apex bNAb CAP256-VRC26.25. These loci were iteratively diversified through homology-directed repair with a library of DNA templates and through in vitro somatic hypermutation and selected with diverse envelope glycoprotein trimers. This approach can identify broader and more-potent apex bNAbs. Three variable 2 (V2) loops of HIV-1 envelope glycoprotein (Env) trimer converge at the Env apex to form the epitope of an important classes of HIV-1 broadly neutralizing antibodies (bNAbs). These V2-glycan/apex antibodies are exceptionally potent but less broad (∼60 to 75%) than many other bNAbs. Their CDRH3 regions are typically long, acidic, and tyrosine sulfated. Tyrosine sulfation complicates efforts to improve these antibodies through techniques such as phage or yeast display. To improve the breadth of CAP256-VRC26.25 (VRC26.25), a very potent apex antibody, we adapted and extended a B cell display approach. Specifically, we used CRISPR/Cas12a to introduce VRC26.25 heavy- and light-chain genes into their respective loci in a B cell line, ensuring that each cell expresses a single VRC26.25 variant. We then diversified these loci through activation-induced cytidine deaminase–mediated hypermutation and homology-directed repair using randomized CDRH3 sequences as templates. Iterative sorting with soluble Env trimers and further randomization selected VRC26.25 variants with successively improving affinities. Three mutations in the CDRH3 region largely accounted for this improved affinity, and VRC26.25 modified with these mutations exhibited greater breadth and potency than the original antibody. Our data describe a broader and more-potent form of VRC26.25 as well as an approach useful for improving the breadth and potency of antibodies with functionally important posttranslational modifications.
Can anteroposterior skeletal pattern be determined from a silhouetted profile photograph? A cross-sectional study

Objective: To determine the degree to which the anteroposterior (AP) skeletal jaw relation can accurately be determined from a silhouetted clinical profile photograph and whether the level of agreement is influenced by patient vertical proportions. Design: Cross-sectional study. Setting: University Dental Hospital of Manchester, United Kingdom. Participants: Specialist orthodontists Method: Eight specialist orthodontists assessed 37 silhouetted profile photographs of individuals aged 11–19 years and determined the class and severity of AP skeletal pattern. These assessments were compared to corresponding lateral cephalometric radiographs, where ANB values, supplemented by an Eastman Correction and a Wits Appraisal, where appropriate, were used for sagittal skeletal classification. Results: The agreement between silhouette and cephalometric AP determination yielded a weighted kappa score of 0.207 (95% confidence interval [CI] 0.135–0.278), which indicates only a fair level of agreement. The silhouetted sagittal skeletal pattern classification, along with severity, agreed with the lateral cephalometric radiograph in 29% of instances. Class III individuals were identified correctly 19.2% of the time. There was a statistically significant difference in kappa scores between the high angle (K= 0.439; 95% CI 0.310–0.568) and low angle (K = 0.068; 95% CI 0.007–0.130) patients (P < 0.001), as well as the high and average angle (K= 0.151; 95% CI 0.031–0.270) patients (P < 0.05). Conclusion: AP skeletal pattern, as determined from a lateral cephalometric radiograph, has only a fair level of agreement to that from a silhouetted profile photograph. Vertical proportions were shown to have a significant effect on the determination of the sagittal skeletal pattern and class III skeletal patterns were shown to be the most difficult to identify from profile silhouettes.
Wang-Landau Monte Carlo simulation of capillary forces at low relative humidity in atomic force microscopy

Abstract A lattice gas model is used with Wang-Landau Monte Carlo sampling to predict the capillary force between a model of an atomic force microscopy (AFM) probe and a smooth surface as a function of separation, relative humidity (RH), and tip hydrophilicity. Completely wetting AFM tips exhibit a maximum in the capillary force as the RH increases, while the magnitude of the capillary force in the presence of partially wetting and partially drying tips is relatively independent of the RH. Capillary forces can also be significant in low RH environments and should not be discounted in AFM studies involving hydrophilic surfaces.
Short-course vasoconstrictors are adequate for esophageal variceal bleeding after endoscopic variceal ligation: A systematic review and meta-analysis

Endoscopic variceal ligation (EVL) with vasoconstrictors has been recommended for acute esophageal variceal bleeding. However, the optimal duration of vasoconstrictors after EVL is controversial. This systematic review and meta-analysis was conducted to explore the efficacy of short-course vasoconstrictors (≤3 days) versus standard combination (3–5 days). A comprehensive literature review was conducted using the PubMed, Embase, and Cochrane library databases with subsequent meta-analysis. The primary outcomes were 5-day rebleeding, mortality, and treatment failure rates. A risk ratio (RR) with 95% confidence interval is used for outcome comparison. Nine randomized studies with 838 patients were included. The initial hemostasis (96.8% vs 97.4%, p = 0.919), 5-day rebleeding (11.2% vs 8.3%, RR = 1.05, 95% CI = 0.62–1.76), mortality (0 vs 1.3%, RR = 0.48, 95% CI = 0.10–2.39), and treatment failure (7.4% vs 5.9%, RR = 1.10, 95% CI = 0.48–2.49) were similar in both groups. Subgroup analysis suggested EVL alone had no significant difference of 5-day re-bleeding (15.9% vs 7.1%, RR = 2.25, 95% CI = 0.87–5.77), mortality (0 vs 0.7%, RR = 0.71, 95% CI = 0.08–6.03), treatment failure (9.6% vs 6.7%, RR = 1.43, 95% CI = 0.54–3.75) compared to standard combination. Clinical heterogeneity was found for the rebleeding rate for the subgroup during sensitivity analysis. EVL with short-course vasoconstrictors is highly efficacious for esophageal variceal bleeding. Further studies are required to determine the genuine need of subsequent vasoconstrictor after successful EVL.
Effects of a combination of botanical actives on skin health and antioxidant status in post‐menopausal women: A randomized, double‐blind, placebo‐controlled clinical trial

Skin aging is one of the most concerning issues during the post‐menopausal period. Despite the promising effects of hormonal therapy, there is still concerned about the long‐term outcomes from the treatment. Therefore, nutraceuticals that contain estrogenic and antioxidative effects have gained a lot of attention as an alternative therapy for slowing down skin age‐related changes in women after menopause.
Perivascular adipose tissue and microvascular endothelial dysfunction in obese mice: Beneficial effects of aerobic exercise in adiponectin receptor (AdipoR1) and peNOSSer1177

In the present study, we aim to investigate the effects of aerobic physical training on perivascular adipose tissue (PVAT)‐induced microvascular dysfunction of the femoral artery in obese mice. Microvascular reactivity was evaluated in control sedentary (c‐SD), obese sedentary (o‐SD) and obese trained (o‐TR) male mice (C57BL6/JUnib), in the absence (PVAT−) or the presence (PVAT+) of femoral artery PVAT. We also analyzed protein expression, vascular nitric oxide (NO) production and reactive oxygen species (ROS) generation in PVAT. The blood glucose, triglycerides and total cholesterol levels were increased in the o‐SD group, when compared with the c‐SD group. The maximal responses and the potency to acetylcholine (ACh) were decreased in PVAT+ compared with PVAT− rings in the o‐SD group, accompanied by a decrease in vascular protein expression of peNOSSer1177, Cu/Zn‐SOD, leptin receptor (Ob‐R) and adiponectin receptor (AdipoR1). The protein expression of leptin increased and that of adiponectin decreased in PVAT. Additionally, vascular NO production was reduced and ROS generation was enhanced in PVAT in the o‐SD group. Aerobic exercise training was effective for normalizing ACh relaxation response, vascular NO production and ROS generation in the o‐TR group. It partially re‐established the vascular protein expression of peNOSSer1177 and the PVAT leptin; normalized the vascular Cu/Zn‐SOD and AdipoR1 protein expressions. In obese sedentary mice, the presence of PVAT is involved in the process of microvascular dysfunction of the femoral artery in a pathway associated with increased inflammation and ROS generation. The aerobic exercise training normalized the vascular response, the NO production and/or bioavailability and oxidative stress, with improved vascular expressions of Cu/Zn‐SOD, peNOSser1177, and AdipoR1.
Characterization of the Oral and Gut Microbiota in Patients with Psoriatic Diseases: A Systematic Review

Advances in technology have led to an increased number of studies investigating the microbiome in patients with psoriasis. This systematic review examined data regarding the oral and gut microbiota in patients with psoriasis and/or psoriatic arthritis and the effect of probiotics on the microbiota and severity of psoriasis. Of 1,643 studies, 23 were included (22 observational, 1 interventional). Studies examined the microbiota using culture or 16S rRNA gene sequencing analysis. All culture-based studies identified an increased presence of oral Candida in patients with psoriasis, whereas small variations in the oral microbiota were found in a 16S rRNA gene-based study. All 16S rRNA gene sequencing based studies agreed that the gut microbiota of patients with psoriatic disease differed from that of healthy controls, but the results were heterogeneous. Probiotics were associated with a significant improvement in the severity of psoriasis, but did not change microbiota. Overall, studies lacked relevant inclusion criteria and baseline information. In conclusion, the role of the microbiota in patients with psoriasis requires further investigation using more robust methods.
Sodium‐glucose cotransporter 2 inhibitors for diabetes mellitus control after kidney transplantation: Review of the current evidence

Sodium‐glucose cotransporter type 2 inhibitors (SGLT2i) are promising drugs to treat chronic kidney disease patients with or without diabetes mellitus (DM). Besides improving glycemic control, SGLT2i are cardioprotective and kidney protective and decrease bodyweight, serum uric acid, blood pressure, albuminuria and glomerular hyperfiltration. These effects may benefit graft function and survival in kidney transplant (KT) patients. In this review, we evaluate data on the efficacy and safety of SGLT2i for KT patients with DM. Eleven studies with 214 diabetic KT patients treated with SGLT2i have been reported. SGLT2i lowered haemoglobin A1c and bodyweight. While glomerular filtration rate may be reduced in the short‐term, it remained similar to baseline after 3–12 months. In two studies, blood pressure decreased and remained unchanged in the others. There were no significant changes in urine protein to creatinine ratio. Regarding safety, 23 patients had urinary tract infections, 2 patients had a genital yeast infection, one had acute kidney injury, and one had mild hypoglycaemia. No cases of ketoacidosis or acute rejection were reported. In conclusion, the limited experience so far suggests that SGLT2i are safe in KT patients with DM, decrease bodyweight and improve glycemic control. However, some of the benefits observed in larger studies in the non‐KT population have yet to be demonstrated in KT recipients, including preservation of kidney function, reduction in blood pressure and decreased proteinuria.
AGPAT3 Gene polymorphisms are associated with milk production traits in Chinese Holstein cows

Abstract The current study reports the identification of previously undiscovered single-nucleotide polymorphisms (SNPs) in the bovine AGPAT3 gene and further investigates their associations with milk production traits. Our results demonstrate that the major allele C of the SNP g.12264 C > T is positively correlated with test-day milk yield, protein percentage and 305-day milk yield. Importantly, in silico analysis showed that the C/T transition at this locus gives rise to two new transcription factor binding sites (TFBS), E2F1 and Nkx3-2. Polymorphism g.18658 G > A was the only SNP associated with milk urea nitrogen (MUN) with the G allele related to an increase in milk urea nitrogen as well as fat percentage. The GG genotype of SNP g.28731 A > G was associated with the highest fat and protein percentage and lowest 305-day milk yield and somatic cell score (SCS). The association between AGPAT3 locus and milk production traits could be utilized in marker-assisted selection for the genetic improvement of milk production traits and, probably in conjunction with other traits, for selection to improve fitness of dairy cattle.
A hitchhiker guide to manta rays: Patterns of association between Mobula alfredi, M. birostris, their symbionts, and other fishes in the Maldives

Despite being among the largest and most charismatic species in the marine environment, considerable gaps remain in our understanding of the behavioural ecology of manta rays (Mobula alfredi, M. birostris). Manta rays are often sighted in association with an array of smaller hitchhiker fish species, which utilise their hosts as a sanctuary for shelter, protection, and the sustenance they provide. Species interactions, rather than the species at the individual level, determine the ecological processes that drive community dynamics, support biodiversity and ecosystem health. Thus, understanding the associations within marine communities is critical to implementing effective conservation and management. However, the underlying patterns between manta rays, their symbionts, and other hitchhiker species remain elusive. Here, we explore the spatial and temporal variation in hitchhiker presence with M. alfredi and M. birostris throughout the Maldives and investigate the factors which may influence association using generalised linear mixed effects models (GLMM). For the first time, associations between M. alfredi and M. birostris with hitchhiker species other than those belonging to the family Echeneidae are described. A variation in the species of hitchhiker associated with M. alfredi and M. birostris was identified, with sharksucker remora (Echeneis naucrates) and giant remora (Remora remora) being the most common, respectively. Spatiotemporal variation in the presence of manta rays was identified as a driver for the occurrence of ephemeral hitchhiker associations. Near-term pregnant female M. alfredi, and M. alfredi at cleaning stations, had the highest likelihood of an association with adult E. naucrates. Juvenile E. naucrates were more likely to be associated with juvenile M. alfredi, and a seasonal trend in E. naucrates host association was identified. Remora were most likely to be present with female M. birostris, and a mean number of 1.5 ± 0.5 R. remora were observed per M. birostris. It is hoped these initial findings will serve as the basis for future work into the complex relationships between manta rays and their hitchhikers.
Validation of the World Health Organization Disability Assessment Schedule (WHODAS 2.0) for individuals with COPD

Abstract Purpose COPD fits the profile of disabling health conditions. This study aims to validate the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) in individuals with COPD. Material and methods 100 participants with COPD responded to the Brazilian 36-item version of the WHODAS 2.0, as well as the Saint George’s Respiratory Questionnaire (SGRQ), and the COPD Assessment Test (CAT). Spirometric data was extracted from medical records. Results The internal consistency analysis showed coefficients for all WHODAS 2.0 domains with a strong correlation (0.70–0.85) except for Life activities, which had a moderate correlation (coefficient = 0.60). In the construct analysis, the coefficients for the WHODAS and SGRQ domains presented a consistent correlation among them, varying from 0.40 to 0.69. No correlation was evidenced among the WHODAS domains and the spirometric data, highlighting that linear measures fail when associated with the functioning of an individual with COPD. Discriminative analysis revealed a capacity for the WHODAS 2.0 to distinguish among COPD different levels of clinical impact obtained from CAT excluding the Getting along domain. Conclusion The WHODAS 2.0 shows as a valid instrument that can sensibly assess functioning differences related to the clinical impact classification level in subjects with COPD. IMPLICATIONS FOR REHABILITATION WHODAS 2.0 is a valid tool to assess functioning in subjects with COPD. WHODAS 2.0 is sensitive to functioning differences related to classification level and to clinical impact in individuals with COPD. As a Patient-Reported Outcome Measure (PROM), WHODAS 2.0 offers the opportunity to develop clinical patient-centered interventions, improving the health care. As a low-cost, easy-to-use tool, WHODAS can be a useful resource in the process of clinical assessment of patient functioning.
Pretreatment resistin levels are associated with erosive disease in early rheumatoid arthritis treated with disease-modifying anti-rheumatic drugs and infliximab

Objective Resistin is an adipocytokine related to insulin resistance and inflammation. We investigated whether resistin is associated with disease activity and inflammation in disease-modifying anti-rheumatic drug (DMARD)-naïve rheumatoid arthritis (RA) patients, whether it has predictive value for radiological disease progression, and whether tumour necrosis factor-α (TNF-α) is involved in these effects. Method Ninety-nine patients with early, DMARD-naïve RA participated in the NEO-RACo study. Patients were treated for the first 4 weeks with a combination of methotrexate, sulfasalazine, hydroxychloroquine, and prednisolone (FIN-RACo treatment). Thereafter, they were randomized to receive either infliximab or placebo added to the combination for 6 months. Patients were followed for 5 years. Disease activity was evaluated using the Disease Activity Score based on 28-joint count–erythrocyte sedimentation rate, radiographs were scored with the modified Sharp–van der Heijde method, and plasma resistin concentrations were measured by immunoassay. Human THP-1 macrophages were used in the in vitro studies. Results A high resistin level at baseline was associated with active inflammatory disease and predicted more rapid radiological progression during 5 year follow-up. Adding infliximab to the DMARD combination delayed radiological progression and overcame the poor predictive value of resistin. Resistin increased TNF-α production in human macrophages, indicating a possible connection between resistin and TNF-α. Conclusion The results suggest that high resistin concentration may be a useful marker to distinguish patients with an increased risk of erosive disease in early active RA, and that adding TNF-α antagonist to the traditional DMARD combination may delay radiological progression of the disease in these patients.
