[PMID: 38681937 PMCID: PMC11043995 DOI: 10.13107/jocr.2024.v14.i04.4406] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Revised: 02/10/2024] [Indexed: 05/01/2024] Open
Abstract
Introduction Tranexamic acid (TXA) is an antifibrinolytic agent, thatagent that reduces substantial blood loss in total knee arthroplasty (TKA) surgeries without increasing the risk of thromboembolic complications. The purpose of our study was to assess the effectiveness and safety of the combined use of intravenousIV and topical TXAtranexamic acid in uncomplicated primary Total knee Arthroplasty (TKA) without complications. Materials and Methods In this prospective study, we enrolled 61 patients who underwent unilateral primary TKR and were randomly divided into two groups: Group I received intravenous (IV) TXA and Group II received both IV and intraarticular (IA) TXA. Patients assigned to Group I received IV TXA preoperatively 30 mins before surgery and postoperatively at 3 and 6 hours after surgery, whereas in the combined group, in addition to IV doses, topical TXA was applied as mop 2 g of TXA diluted in 30 mL of isotonic sodium chloride solution) intraarticularly for about 5 minutes before closing the arthrotomy. We measured total blood loss (TBL), ) and mean reduction in haemoglobin (Hb) levels as primary outcomes. Transfusion rates, incidence of thromboembolic events (TE), and other adverse effects as secondary outcomes. Total blood loss TBL and Hb drops was were noted on the 3rd post-operative day. All the patients were followed-up for 6 months to note the incidence of deep venous thrombosisDVT and Thromboembolic Events (TE). An Iindependent t-test was used to evaluate between--group differences. P < 0.05 as is the cut-off for statistically significant differences. Results The Total blood loss (TBL) in Group I was 780.05 ± 158.05 mL, compared to 660.80 ± 156.45 mL in Group II. (P < 0.001). The Hb drop was significantly lower in IV TXA group (2.3 ± 0.37) than the combined TXA group (1.40 ± 0.32). Furthermore, both groups required no transfusions. No thromboembolic complications was were noted postoperatively and at 6 6-month follow-up. Conclusion TXATranexamic acid in total knee replacement surgery effectively decreases blood loss and significantly reduces the need for blood transfusions. Based on our study, the combined use of intravenous (IV) and IAintraarticular TXA in total knee replacement was found to be superior in reducing blood loss and significantly reducing the need for blood transfusions in TKA.

The Functional Outcome of Surgical Management of Spondylolisthesis with Posterior Stabilization and Fusion. J Orthop Case Rep 2024; 14:119-124. [PMID: 38292104 PMCID: PMC10823822 DOI: 10.13107/jocr.2024.v14.i01.4170] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Revised: 11/02/2023] [Indexed: 02/01/2024] Open
Abstract
Introduction Spondylolisthesis is a spinal condition characterized by the forward displacement of one vertebra over another, leading to instability and associated symptoms. Surgical intervention is often recommended for patients with symptomatic spondylolisthesis unresponsive to conservative treatment. The objective of this study was to analyze the functional outcomes of surgical management utilizing posterior stabilization and fusion techniques in patients with spondylolisthesis. Materials and Methods This is a prospective study conducted on 30 patients who underwent surgical treatment for spondylolisthesis with posterior trans-pedicular screw fixation with conventional or reduction screws and fusion. Meyerding's grade of listhesis, Japanese Orthopaedic Association (JOA) score, Oswestry disability index (ODI) score and pain scores such as visual analog scale (VAS), numerical rating scale 11 (NRS-11), and pain relief rate were used to analyze the functional outcome. Results Postoperatively, Meyerding's grade of listhesis and the JOA score had improved significantly. The ODI score and pain scores such as VAS, NRS-11, and pain relief rate were better after surgical interventions. There was full motor recovery in 13 patients and 14 patients had full sensory recovery, while six patients had sensory blunting at the time of the time of the last follow-up. Twenty-six (80.7%) patients had clinically successful results and radiological/clinical fusion while four of the patients did not achieve a clinically successful result and radiological/clinical fusion. The average time for bony fusion was 5.58 months with the earliest being 4 months and the latest 12 months. Intraoperatively, one patient had screw slippage and one had a dural tear. Postoperatively, four patients had infection, two patients were presented with deep infection, and the instrumentation had been removed. Conclusion This study demonstrated favorable functional outcomes and improvements in pain, disability, and quality of life measures following surgical intervention.

Complete mesocolic excision versus standard resection for colon cancer: a systematic review and meta-analysis of perioperative safety and an evaluation of the use of a robotic approach. Tech Coloproctol 2023; 27:995-1005. [PMID: 37414915 DOI: 10.1007/s10151-023-02838-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Accepted: 06/17/2023] [Indexed: 07/08/2023]
Abstract
PURPOSE Complete mesocolic excision (CME) has been associated with improved oncological outcomes in treatment of colon cancer. However, widespread adoption is limited partly because of the technical complexity and perceived risks of the approach. The aim of out study was to evaluate the safety of CME compared to standard resection and to compare robotic versus laparoscopic approaches. METHODS Two parallel searches were undertaken in MEDLINE, Embase and Web of Science databases 12 December 2021. The first was to evaluate IDEAL stage 3 evidence to compare complication rates as a surrogate marker of perioperative safety between CME and standard resection. The second independent search compared lymph node yield and survival outcomes between minimally invasive approaches. RESULTS There were four randomized control trials (n = 1422) comparing CME to standard resection, and three studies comparing laparoscopic (n = 164) to robotic (n = 161) approaches. Compared to standard resection, CME was associated with a reduction in Clavien-Dindo grade 3 or higher complication rates (3.56% vs. 7.24%, p = 0.002), reduced blood loss (113.1 ml vs. 137.6 ml, p < 0.0001) and greater mean lymph node harvest (25.6 vs. 20.9 nodes, p = 0.001). Between the robotic and laparoscopic groups, there were no significant differences in complication rates, blood loss, lymph node yield, 5-year disease-free survival (OR 1.05, p = 0.87) and overall survival (OR 0.83, p = 0.54). CONCLUSIONS Our study demonstrated improved safety with CME. There was no difference in safety or survival outcomes between robotic and laparoscopic CME. The advantage of a robotic approach may lie in the reduced learning curve and an increased penetration of minimally invasive approach to CME. Further studies are required to explore this.

Childhood-Onset Lupus Nephritis in the Childhood Arthritis and Rheumatology Research Alliance Registry: Short-Term Kidney Status and Variation in Care. Arthritis Care Res (Hoboken) 2023; 75:1553-1562. [PMID: 36775844 PMCID: PMC10500561 DOI: 10.1002/acr.25002] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Revised: 07/14/2022] [Accepted: 08/16/2022] [Indexed: 11/10/2022]
Abstract
OBJECTIVE The goal was to characterize short-term kidney status and describe variation in early care utilization in a multicenter cohort of patients with childhood-onset systemic lupus erythematosus (cSLE) and nephritis. METHODS We analyzed previously collected prospective data from North American patients with cSLE with kidney biopsy-proven nephritis enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry from March 2017 through December 2019. We determined the proportion of patients with abnormal kidney status at the most recent registry visit and applied generalized linear mixed models to identify associated factors. We also calculated frequency of medication use, both during induction and ever recorded. RESULTS We identified 222 patients with kidney biopsy-proven nephritis, with 64% class III/IV nephritis on initial biopsy. At the most recent registry visit at median (interquartile range) of 17 (8-29) months from initial kidney biopsy, 58 of 106 patients (55%) with available data had abnormal kidney status. This finding was associated with male sex (odds ratio [OR] 3.88, 95% confidence interval [95% CI] 1.21-12.46) and age at cSLE diagnosis (OR 1.23, 95% CI 1.01-1.49). Patients with class IV nephritis were more likely than class III to receive cyclophosphamide and rituximab during induction. There was substantial variation in mycophenolate, cyclophosphamide, and rituximab ever use patterns across rheumatology centers. CONCLUSION In this cohort with predominately class III/IV nephritis, male sex and older age at cSLE diagnosis were associated with abnormal short-term kidney status. We also observed substantial variation in contemporary medication use for pediatric lupus nephritis between pediatric rheumatology centers. Additional studies are needed to better understand the impact of this variation on long-term kidney outcomes.

Cohort profile: the ESC EURObservational Research Programme Non-ST-segment elevation myocardial infraction (NSTEMI) Registry. EUROPEAN HEART JOURNAL. QUALITY OF CARE & CLINICAL OUTCOMES 2022; 9:8-15. [PMID: 36259751 DOI: 10.1093/ehjqcco/qcac067] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/07/2022] [Accepted: 10/11/2022] [Indexed: 11/12/2022]
Abstract
AIMS The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation. METHODS AND RESULTS Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin. CONCLUSION The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

Abstract
OBJECTIVE To examine characteristics of beneficiaries, physicians, and their practice sites associated with greater use of low-value services (LVS) using LVS measures that reflect current care practices. DATA SOURCES This study was conducted in the context of a large, nationwide primary care redesign initiative (Comprehensive Primary Care Plus), using Medicare claims data in 2018. STUDY DESIGN We examined beneficiary-level total counts of LVS based on the existing 31 claims-based measures updated by excluding three services provided with diminishing frequency to Medicare beneficiaries and by replacing these with more recently identified LVS. We estimated hierarchical linear models with an extensive list of beneficiary, physician, and practice site characteristics to examine the contribution of characteristics at each level in predicting greater use of LVS. We also examined the proportion of variation in LVS use attributable to the set of characteristics at each level. DATA COLLECTION/EXTRACTION METHODS The study included 5,074,642 Medicare fee-for-service beneficiaries attributed to 32,406 primary care physicians in 11,009 primary care practice sites. PRINCIPAL FINDINGS Patients with disabilities, end-stage renal disease, and those in regions with higher poverty rates receive 10 (standard error [SE] = 3.0), 80 (SE = 14.0), and 10 (SE = 1.0) more LVS per 1000 beneficiaries across all 31 measures combined than patients without such attributes, respectively. Greater physician comprehensiveness and an increase in the number of primary care practitioners at a practice were associated with 40 (SE = 20.0) and 20 (SE = 6.0) fewer LVS per 1000 beneficiaries, respectively. Yet, the explanatory variables we examined only account for 11 percent of the variation in LVS use, with most of the variation (87 percent) being due to unobserved differences at the beneficiary level. CONCLUSIONS Unexplained residual variation, from underlying patient preferences and behavior of non-primary care providers, could be important determinants of LVS use.

Intraarticular steroids as DMARD-sparing agents for juvenile idiopathic arthritis flares: Analysis of the Childhood Arthritis and Rheumatology Research Alliance Registry. Pediatr Rheumatol Online J 2022; 20:107. [PMID: 36434731 PMCID: PMC9701017 DOI: 10.1186/s12969-022-00770-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Accepted: 11/08/2022] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND Children with juvenile idiopathic arthritis (JIA) who achieve a drug free remission often experience a flare of their disease requiring either intraarticular steroids (IAS) or systemic treatment with disease modifying anti-rheumatic drugs (DMARDs). IAS offer an opportunity to recapture disease control and avoid exposure to side effects from systemic immunosuppression. We examined a cohort of patients treated with IAS after drug free remission and report the probability of restarting systemic treatment within 12 months. METHODS We analyzed a cohort of patients from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry who received IAS for a flare after a period of drug free remission. Historical factors and clinical characteristics and of the patients including data obtained at the time of treatment were analyzed. RESULTS We identified 46 patients who met the inclusion criteria. Of those with follow up data available 49% had restarted systemic treatment 6 months after IAS injection and 70% had restarted systemic treatment at 12 months. The proportion of patients with prior use of a biologic DMARD was the only factor that differed between patients who restarted systemic treatment those who did not, both at 6 months (79% vs 35%, p < 0.01) and 12 months (81% vs 33%, p < 0.05). CONCLUSION While IAS are an option for all patients who flare after drug free remission, it may not prevent the need to restart systemic treatment. Prior use of a biologic DMARD may predict lack of success for IAS. Those who previously received methotrexate only, on the other hand, are excellent candidates for IAS.

Incompleteness of the large-N analysis of the O(N) models: Nonperturbative cuspy fixed points and their nontrivial homotopy at finite N. Phys Rev E 2022; 106:054105.

Abstract
We summarize the usual implementations of the large-N limit of O(N) models and show in detail why and how they can miss some physically important fixed points when they become singular in the limit N→∞. Using Wilson's renormalization group in its functional nonperturbative versions, we show how the singularities build up as N increases. In the Wilson-Polchinski version of the nonperturbative renormalization group, we show that the singularities are cusps, which become boundary layers for finite but large values of N. The corresponding fixed points being never close to the Gaussian, are out of reach of the usual perturbative approaches. We find four new fixed points and study them in all dimensions and for all N>0 and show that they play an important role for the tricritical physics of O(N) models. Finally, we show that some of these fixed points are bivalued when they are considered as functions of d and N thus revealing important and nontrivial homotopy structures. The Bardeen-Moshe-Bander phenomenon that occurs at N=∞ and d=3 is shown to play a crucial role for the internal consistency of all our results.

Abstract
Abstract
Aim
Post-operative urinary retention (POUR) is a recognised complication of inguinal hernia repair (IHR). Reported incidence is variable, and reporting of risk factors, contradictory. We aimed to report the rate, risk factors and impact of POUR post IHR.
Methods
A prospective international observational study was performed with 4 week data collection from each centre (March-November 2021). Patients undergoing elective open/minimally-invasive IHR were eligible. Exclusion criteria included a urethral catheter at baseline. Preoperative/intraoperative/postoperative variables were analysed and data recorded via REDCap. Multivariate analysis was performed with a primary outcome of development of POUR. Secondary outcomes were risk factors for, and implications of, POUR.
Results
4,153 patients (205 centres; 35 countries) were registered. Mean age was 54.7 years (18–95) and BMI 26.5 (16–6). 80.4% (n=3167) were performed open and 17% (n=674) minimally-invasively. The overall rate of POUR was 5.8% (n=225) and increasd >9% in male patients aged >65 years old. Risk factors associated with POUR included: higher preoperative IPSS scores (mean 9.4 vs 5.6 in non-POUR cohort, p<0.001), diagnosis of BPH (p<0.001), pre-operative constipation (p=0.009) defined as no bowel opening for two days pre-operatively and pre-operative post void residual volumes (<0.001). 37% of patients developing POUR required an unplanned hospital admission.
Conclusion
This study suggests a global POUR rate of approximately 5% following elective IHR and confirm a significant impact of POUR on patients and hospital services. Findings highlight several risk factors and confirm the IPSS score as a potential risk stratification tool.

Abstract
BACKGROUND Social determinants of health (SDH) greatly influence outcomes during the first year of treatment in rheumatoid arthritis, a disease similar to polyarticular juvenile idiopathic arthritis (pJIA). We investigated the correlation of community poverty level and other SDH with the persistence of moderate to severe disease activity and functional disability over the first year of treatment in pJIA patients enrolled in the Childhood Arthritis and Rheumatology Research Alliance Registry. METHODS In this cohort study, unadjusted and adjusted generalized linear mixed effects models analyzed the effect of community poverty and other SDH on disease activity, using the clinical Juvenile Arthritis Disease Activity Score-10, and disability, using the Child Health Assessment Questionnaire, measured at baseline, 6, and 12 months. RESULTS One thousand six hundred eighty-four patients were identified. High community poverty (≥20% living below the federal poverty level) was associated with increased odds of functional disability (OR 1.82, 95% CI 1.28-2.60) but was not statistically significant after adjustment (aOR 1.23, 95% CI 0.81-1.86) and was not associated with increased disease activity. Non-white race/ethnicity was associated with higher disease activity (aOR 2.48, 95% CI: 1.41-4.36). Lower self-reported household income was associated with higher disease activity and persistent functional disability. Public insurance (aOR 1.56, 95% CI 1.06-2.29) and low family education (aOR 1.89, 95% CI 1.14-3.12) was associated with persistent functional disability. CONCLUSION High community poverty level was associated with persistent functional disability in unadjusted analysis but not with persistent moderate to high disease activity. Race/ethnicity and other SDH were associated with persistent disease activity and functional disability.

Abstract
Abstract
Aim
With the evolution of robotic surgery, the adoption of a robotic approach to perform rectopexy, in particular ventral mesh repair (VMR), is gaining popularity. We aimed to audit clinical outcomes following introduction of a robotic rectopexy (RR) programme and compare outcomes to internationally published randomised controlled trials (RCTs).
Method
Consecutive patients undergoing RR from July to December were included. The daVinci Xi surgical system (Intuitive, California) was used for all procedures using a modified left lower abdominal approach. Where VMR was performed, a 4 x 18cm Permacol mesh was used as standard and posterior fixation using ethibond. We compared operative times and 30-day clinical outcomes to international data.
Results
Over a six-month period, thirteen RR were performed (n = 1 sutured, n = 2 resection sutured, n = 10 VMR). All patients were female with a mean age of 60.4 years (SD 14.12). Mean time from 1st consultation to surgery was 10.7 months. Three patients had an external rectal prolapse and ten patients a rectocoele confirmed on dynamic MRI. Seven patients had co-existing urinary symptoms impacting on quality of life. Median docking time was 23 minutes and median robotic operative time was 194 minutes (156 minutes reported). There were no conversions (2.5% reported). Average length of stay was 5 days (4 days reported) and there were no 30-day morbidities (8.6% reported) or readmissions.
Conclusions
Robotic rectopexy can be performed with appropriate operative times and clinical outcomes and offers a superior operative platform for critical operative steps including rectal mobilisation and VMR mesh placement and suturing.

Abstract
Abstract
Aim
Rectopexy is a surgical procedure commonly used to correct rectal prolapse. Several studies have investigated different approaches (abdominal, perineal) and techniques (open, laparoscopic, robotic) in this field however reporting outcomes vary significantly among studies impeding comparison of techniques. We aimed to comprehensively analyse primary outcome reporting methods following rectopexy in published literature.
Method
A systematic search was performed in keeping with PRISMA guidelines and search protocol registered with PROSPERO. Published databases were searched using the following terms: “rectopexy”, “abdominal rectopexy” and “rectopexy outcomes”. Randomised controlled trials, comparative and non-comparative prospective and retrospective studies published between 1992 and 2019 were included for analysis. Review articles, letters, editorials, abstracts, and non-English language studies were excluded. A narrative description of outcomes was reported.
Results
A total of 1089 articles were screened, and 32 articles were identified as suitable for inclusion, reporting on 1780 patients who underwent rectopexy surgery. Over 30 unique methods of reporting outcomes were recorded, with the most common being the rate of recurrence (n = 15), Cleveland Clinic Faecal Incontinence score (CCIS) (n = 11), and customised symptom questionnaires (n = 10). Many studies recognised the impact of symptoms of rectal prolapse on patients’ quality of life (QoL) however, few utilised standardised quality of life scores to evaluate the outcome of the procedures.
Conclusions
As surgical technique evolves in rectopexy, incorporating minimally invasive surgery and robotic surgery, it is important that outcome reporting is standardised to facilitate transparent comparison. Improving patient QoL is the mainstay of surgical intervention and it is important that QoL outcome measures are incorporated.

Abstract
BACKGROUND Despite decades of use, the magnitude of efficacy of narrowband ultraviolet B (NB-UVB) phototherapy for atopic dermatitis (AD) beyond industry-sponsored trials remains unclear. AIM To evaluate the clinical efficacy of NB-UVB in AD under real-world conditions. METHODS We conducted a historical inception cohort study using automated recording of dispensed drugs to provide an objective treatment outcome in a large population catchment of 420 000 people over 15 years. We analysed clinical treatment outcomes, recorded multicentre and prospectively over 15 years, of a large AD treatment cohort (n = 844), along with the drugs dispensed to this cohort. RESULTS The majority (70%) of patients with AD received significantly fewer topical corticosteroids (TCS) during the 12-month window after finishing NB-UVB compared with the 12-month window before starting the treatment (median reduction from 37.5 to 19.7 g/month). The number of patients dispensed with oral corticosteroids and antihistamines also dropped significantly (from 20% to 10% and from 69% to 31%, respectively), while all AD-unrelated drugs dispensed remained unchanged. Clinically, NB-UVB treatment achieved a 'clear' or 'almost clear' status in 48.7% of patients, while 20.4% achieved 'moderate clearance'. Treatment outcomes scores were validated by a strong correlation with reduction in AD-specific drug treatment. CONCLUSION Our data confirm the significant efficacy of NB-UVB for AD under conditions of routine care.

Abstract
The objective of this study was to investigate the effect of altering autumn pasture availability and farm system intensity on the productivity of spring-calving dairy cows during autumn. A total of 144 Holstein-Friesian and Holstein-Friesian × Jersey crossbred dairy cows were randomly assigned to 2 whole farm system (FS) intensities and 3 autumn pasture availability (PA; measured above 3.5 cm) treatments in a 2 × 3 factorial arrangement. The 2 farm systems consisted of a medium intensity (MI: 2.75 cows/ha, target postgrazing sward height of 4.0-4.5 cm) and high intensity system (HI: 3.25 cows/ha, target postgrazing sward height of 3.5-4.0 cm, + 1.8 kg of concentrate dry matter [(DM)/cow per day]. Within each farm system treatment, cows were further subdivided into 3 different PA management strategies: high PA (HPA), medium PA (MPA), and low PA (LPA). The experimental period lasted for 11 wk from September 1 to housing of all animals on November 20 (±2 d) over 3 yr (2017-2019, inclusive). To establish the different average pasture covers for each PA treatment during autumn and in particular at the end of the grazing season, grazing rotation length was extended by +13 and +7 d for HPA and MPA, respectively, beyond that required by LPA (37 d). There were no significant FS × PA interactions for any of the pasture, dry matter intake, or milk production and composition variables analyzed. There were also no differences in pregrazing sward characteristics or sward nutritive value between FS with the exception of daily herbage allowance, which was reduced for HI system (12.2 vs. 14.2 kg of DM/cow). Milk and milk solid yield were greater for HI groups (15.9 and 1.55 kg/cow per day, respectively) compared with MI (15.4 and 1.50 kg/cow per day, respectively). Mean paddock pregrazing herbage mass was significantly higher with increased PA ranging from a mean of 1,297 kg of DM/ha for LPA to 1,718 and 2,111 kg of DM/ha of available pasture for MPA and HPA, respectively. Despite large differences in pregrazing herbage mass, there was no difference in cumulative pasture production and only modest differences in grazing efficiency and sward nutritive value between PA treatments. On average, closing pasture covers were 420, 650, and 870 kg of DM/ha for LPA, MPA, and HPA, respectively, on December 1. In addition to maintaining similar grazing season lengths and achieving big differences in availability of pasture on farm into late autumn, PA treatment had no significant effect on dry matter intake, milk production, and body condition score during the study period. The results of this study indicate that greater cow performance and pasture utilization can be achieved through a greater daily concentrate allocation along with an increased stocking rate. Moreover, the potential to adapt grazing management practices to increase the average autumn pasture cover in intensive grazing systems is highlighted. In addition, a high dependence on high-quality grazed pasture during late autumn can be ensured without compromising grazing season length while also allowing additional pasture to be available for the subsequent spring.

Differential Roles of the mTOR-STAT3 Signaling in Dermal γδ T Cell Effector Function in Skin Inflammation. Cell Rep 2020; 27:3034-3048.e5.

Abstract
Dermal γδT cells play critical roles in skin homeostasis and inflammation. However, the underlying molecular mechanisms by which these cells are activated have not been fully understood. Here, we show that the mechanistic or mammalian target of rapamycin (mTOR) and STAT3 pathways are activated in dermal γδT cells in response to innate stimuli such as interleukin-1β (IL-1β) and IL-23. Although both mTOR complex 1 (mTORC1) and mTORC2 are essential for dermal γδT cell proliferation, mTORC2 deficiency leads to decreased dermal γδT17 cells. It appears that mitochondria-mediated oxidative phosphorylation is critical in this process. Notably, although the STAT3 pathway is critical for dermal Vγ4T17 effector function, it is not required for γδ6T17 cells. Transcription factor IRF-4 activation promotes dermal γδT cell IL-17 production by linking IL-1β and IL-23 signaling. The absence of mTORC2 in dermal γδT cells, but not STAT3, ameliorates skin inflammation. Taken together, our results demonstrate that the mTOR-STAT3 signaling differentially regulates dermal γδT cell effector function in skin inflammation. Cai et al. demonstrate that the mTOR and STAT3 signaling pathways differentially regulate dermal Vγ4 and Vγ6 T cell effector function, leading to distinct outcomes in skin inflammation.

Abstract
Background Laparoscopy, by its minimally invasive nature, has revolutionized digestive and particularly colorectal surgery by decreasing post-operative pain, morbidity, and length of hospital stay. In this trial, we aim to assess whether low pressure in laparoscopic colonic surgery (7 mm Hg instead of 12 mm Hg) could further reduce pain, analgesic consumption, and morbidity, resulting in a shorter hospital stay. Methods and analysis The PAROS trial is a phase III, double-blind, randomized controlled trial. We aim to recruit 138 patients undergoing laparoscopic colectomy. Participants will be randomly assigned to either a low-pressure group (7 mm Hg) or a standard-pressure group (12 mm Hg). The primary outcome will be a comparison of length of hospital stay between the two groups. Secondary outcomes will compare post-operative pain, consumption of analgesics, morbidity within 30 days, technical and oncological quality of the surgical procedure, time to passage of flatus and stool, and ambulation. All adverse events will be recorded. Analysis will be performed on an intention-to-treat basis. Trial registration This research received the approval from the Committee for the Protection of Persons and was the subject of information to the ANSM. This search is saved in the ID-RCB database under registration number 2018-A03028–47. This research is retrospectively registered January 23, 2019, at http://clinicaltrials.gov/ed under the name “LaPAroscopic Low pRessure cOlorectal Surgery (PAROS)”. This trial is ongoing.

Abstract
We evaluate methods to calculate the economic value of protected areas derived from the improved mental health of visitors. A conservative global estimate using quality-adjusted life years, a standard measure in health economics, is US$6 trillion p.a. This is an order of magnitude greater than the global value of protected area tourism, and two to three orders greater than global aggregate protected area management agency budgets. Future research should: refine this estimate using more precise methods; consider interactions between health and conservation policies and budgets at national scales; and examine links between personalities and protected area experiences at individual scale.

Quantitative analysis of topical treatments in atopic dermatitis: unexpectedly low use of emollients and strong correlation of topical corticosteroid use both with depression and concurrent asthma. Br J Dermatol 2019; 182:1017-1025.

Abstract
BACKGROUND Despite decades of use, the actual amounts of topical corticosteroids (TCS) and emollients used in moderate-to-severe atopic dermatitis (AD) under real-world conditions are unknown. Thus, it remains unclear whether inadequate use is widespread. OBJECTIVES To quantify the use of TCS and emollients in moderate-to-severe AD. METHODS Double-blinded drug prescribing was recorded prospectively at the point of drug dispensing within a catchment area of approximately 450 000 people over a 31-year period in a population-based cohort marked by failure of disease control in primary care (n = 844). For each patient, prescribing was recorded over a 12-month period in order to minimize fluctuations. RESULTS This approach resulted in a near-complete dataset, which was essentially free of reporting bias and recording bias. Atopic comorbidities matched expected frequencies. Median use of TCS was statistically significantly higher in juvenile patients (age < 16 years) compared with adult patients (49·2 vs. 38·1 g per month), in male vs. female patients (46·8 vs. 29·7 g per month) and in patients receiving concurrent asthma treatment (40·4 vs. 26·7 g per month). TCS use was strongly associated with antidepressant treatment. Emollient use was unexpectedly low with a median of 9·6 g per day (range 1·4-30·1). Results were replicated in an independent validation cohort. CONCLUSIONS Deficient use of emollients may be a factor contributing to AD severity. Our analysis showed that the use of TCS does not exceed current guidelines. Accurate quantification of topical treatments provides a widely accessible strategy to measure the real-world impact of novel AD treatments. What's already known about this topic? Both emollient and topical corticosteroid (TCS) use have been a mainstay of atopic dermatitis (AD) treatment for over 60 years. The actual quantities used by patients under real-world conditions are unknown. What does this study add? The real-world use of emollients is fourfold lower than the amount recommended in current guidelines. Underuse of emollients may be a significant factor in disease exacerbation. The use of TCS is significantly higher in male patients and is higher in patients with AD who also have asthma. The use of TCS is strongly associated with concurrent antidepressant treatment.

Abstract
OBJECTIVES We conducted a cluster-randomized feasibility trial of 90-minute Chlamydia trachomatis tests and same day on-site treatment ('Test n Treat/TnT') in six technical colleges in London, England, to assess TnT uptake rates; follow-up rates; prevalence of C. trachomatis at baseline and 7 months; time to treatment; acceptability of TnT. METHODS Participants completed questionnaires and provided genitourinary samples at baseline and 7 months. Participants were informed that baseline samples would not be tested for 7 months and were advised to get screened independently. Colleges were randomly allocated 1:1 to intervention (TnT) or control (no TnT). One month and 4 months post recruitment, participants at intervention colleges were texted invitations for on-site free C. trachomatis tests. A purposive sample of students who did/did not attend for screening were interviewed (n = 26). RESULTS Five hundred and nine sexually active students were recruited: median age 17.9 years, 47% male, 50% black ethnicity, 55% reporting two or more sexual partners in the previous year. TnT uptake was 13% (33/259; 95% CI 8.9-17.4%) at 1 month and 10% (26/259; 6.7-14.4%) at 4 months with overall C. trachomatis positivity 5.1% (3/59; 1.1-14.2%). Follow-up at 7 months was 62% (317/509) for questionnaires and 52% (264/509) for samples. C. trachomatis prevalence was 6.2% (31/503) at baseline and 6.1% (16/264) at 7 months. Median time from test to treatment was 15 h. Interviews suggested low test uptake was associated with not feeling at risk, perceptions of stigma, and little knowledge of sexually transmitted infections (STIs). CONCLUSIONS Despite high C. trachomatis rates at baseline and follow-up, uptake of testing was low. Like many countries, England urgently needs better sex education, including making STI testing routine/normal. Trial registration ISRCTN58038795.

A Critical Role of the IL-1β-IL-1R Signaling Pathway in Skin Inflammation and Psoriasis Pathogenesis. J Invest Dermatol 2018; 139:146-156.

Abstract
The IL-1 signaling pathway has been shown to play a critical role in the pathogenesis of chronic, autoinflammatory skin diseases such as psoriasis. However, the exact cellular and molecular mechanisms have not been fully understood. Here, we show that IL-1β is significantly elevated in psoriatic lesional skin and imiquimod-treated mouse skin. In addition, IL-1R signaling appears to correlate with psoriasis disease progression and treatment response. IL-1 signaling in both dermal γδ T cells and other cells such as keratinocytes is essential to an IMQ-induced skin inflammation. IL-1β induces dermal γδ T cell proliferation and IL-17 production in mice. In addition, IL-1β stimulates keratinocytes to secrete chemokines that preferentially chemoattract peripheral CD27- CCR6+IL-17 capable of producing γδ T cells (γδT17). Further studies showed that endogenous IL-1β secretion is regulated by skin commensals to maintain dermal γδT17 homeostasis in mice. Mouse skin associated with Corynebacterium species, bacteria enriched in human psoriatic lesional skin, has increased IL-1β and dermal γδT17 cell expansion. Thus, the IL-1β-IL-1R signaling pathway may contribute to skin inflammation and psoriasis pathogenesis via the direct regulation of dermal IL-17-producing cells and stimulation of keratinocytes for amplifying inflammatory cascade.

Abstract
BACKGROUND Narrowband ultraviolet B (NB-UVB) treatment for psoriasis is considered expensive. However, existing data are based on estimates and do not consider indirect cost savings. OBJECTIVES To define the actual costs of NB-UVB incurred by the service provider, as well as treatment-associated cost savings. METHODS We performed data linkage of (i) comprehensive treatment records and (ii) prescribing data for all NB-UVB treatment episodes spanning 6 years in a population of 420 000. We minimized data fluctuation by compiling data from four independent treatment sites, and using drug prescriptions unrelated to psoriasis as a negative control. RESULTS National Health Service Tayside spent an average of £257 per NB-UVB treatment course (mean 257 ± 63, range 150-286, across four independent treatment sites), contrasting sharply with the estimate of £1882 used by the U.K. National Institute for Health and Care Excellence. The cost of topical treatments averaged £128 per patient in the 12 months prior to NB-UVB, accounting for 42% of the overall drug costs incurred by these patients. This was reduced by 40% to £53 per patient over the 12-month period following NB-UVB treatment, while psoriasis-unrelated drug prescription remained unchanged, suggesting disease-specific effects of NB-UVB. The data were not due to site-specific factors, as confirmed by highly similar results observed between treatment sites operated by distinct staff. Finally, we detail all staff hours directly and indirectly involved in treatment, allowing direct translation of cost into other healthcare systems. CONCLUSIONS NB-UVB is a low-cost treatment; cost figures currently used in health technology appraisals are an overestimate based on the data presented here. Creating or extending access to NB-UVB is likely to offer additional savings by delaying or avoiding costly third-line treatments for many patients.

Abstract
For comparative effectiveness research to be effective, patients and providers must collaborate in shared decision making (SDM) to make evidence-based clinical decisions that align with patient preferences. We conducted a systematic review to examine patient and provider attitudes toward and engagement in SDM in the USA. Searches in PubMed and PsycINFO identified 1585 articles published between July 2006 and December 2016, of which 290 were screened in for coding and analysis. We found that patients and providers have generally positive attitudes toward SDM, but actual engagement in SDM behavior is lagging. Translation of positive attitudes into behavior could be achieved through policies that support key SDM processes of sharing evidence, considering patient preferences and discussing the relative advantages of different clinical options.

A Phase II Toxicity End Point Trial (ICORG 99-09) of Accelerated Dose-escalated Hypofractionated Radiation in Non-small Cell Lung Cancer. Clin Oncol (R Coll Radiol) 2017; 30:30-38. [PMID: 29097074 DOI: 10.1016/j.clon.2017.10.010] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2017] [Revised: 09/18/2017] [Accepted: 09/21/2017] [Indexed: 12/25/2022]
Abstract
AIMS The objective of this phase II clinical trial was to prospectively evaluate the safety and efficacy of accelerated hypofractionated three-dimensional conformal radiation therapy (3DCRT) in localised non-resectable/non-operable non-small cell lung cancer (NSCLC). MATERIALS AND METHODS Sixty patients with stage I-III NSCLC were enrolled in a prospective single-arm All Ireland Co-operative Oncology Research Group (ICORG 99-09) toxicity end point phase II trial. The protocol allocated patients between three radiation schedule dose levels (60, 66 or 72 Gy, in 20, 22 and 24 fractions, respectively, 3 Gy daily, five fractions per week) according to combined lung V25Gy (V25Gy ≤ 30%) with built-in early stopping toxicity rules. The primary end point was toxicity with evaluation of dose-limiting toxicity. The secondary objectives included radiological tumour response rate at 3 months after the completion of radiation therapy and the thoracic progression-free survival time. RESULTS Sixty patients were recruited from August 1999 to June 2009. Forty-nine patients were included in the primary per-protocol analysis. Eleven patients were not evaluable. In the first 30 evaluable patient cohort, severe oesophageal toxicity was reported in two patients (2/49; 4% experiencing grade 5 oesophageal late toxicity, related to the 97% oesophageal length). The trial was temporarily closed and was then reopened to validate an oesophageal dose volume constraint (DVC) of limiting the length of oesophagus fully encompassed by the 97% isodose to less than 1 cm (applied to 21 patients). The trial prospectively showed the safety of the oesophageal DVC, with no oesophageal toxicity above grade 3 thereafter. Thirty-nine per cent of patients had disease progression at 3-4 months after radiotherapy, 22% had stable disease, 20% had a complete response and 14% had a partial response. The median overall survival was 13.6 months (95% confidence interval 10.5-16.7) and overall survival at 1 and 3 years was 57% and 29%, respectively. CONCLUSION A strategy using accelerated hypofractionated 3DCRT is feasible and reasonably safe for patients with inoperable NSCLC. It is safe to deliver for centrally located tumours if DVCs are applied to the oesophagus, which is the primary dose-limiting toxicity. Further studies are required to assess the efficacy of hypofractionated regimens for centrally located tumours using an oesophageal DVC and monitoring for oesophageal toxicity.
