Evaluating the Efficacy and Safety of Combined Administration of Systemic and Topical Tranexamic Acid in Total Knee Arthroplasty.

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.

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.

Age-related patterns in high-risk alcohol and cannabis use and their associations with positive and negative affect in young adulthood.

OBJECTIVE: We examined age-varying associations between young adult simultaneous alcohol and marijuana/cannabis use (SAM) and heavy episodic drinking (HED) and positive and negative affect to inform harm reduction efforts. METHODS: Young adults reporting past-year alcohol use (n = 556; ages 19-25) were recruited in a state where alcohol and nonmedical cannabis use was legal for those 21 +. Participants provided 24 repeated monthly assessments. Among those reporting past-month cannabis use on at least one survey, logistic time-varying effect models estimated (1) the age-varying prevalence of and associations between past-month SAM and HED and (2) age-varying unique associations of affect with SAM and HED. RESULTS: There was a positive age-varying association between HED and SAM over time that was highest at age 19 (OR = 7.56), decreased until age 20.7 (OR = 3.39), increased until age 23.0 (OR = 4.85), and decreased until the association became non-significant by age 25. Negative affect was positively associated with SAM from ages 20.7 to 23.0, peaking at age 21.8 (OR = 1.36). Positive affect was positively associated with HED from ages 19.4 to 20.4 (peak OR = 1.25) and ages 22.5 to 24.5 (peak OR = 1.38). In contrast, positive affect was not uniquely associated with SAM nor negative affect with HED across ages 19-25. CONCLUSIONS: While HED and SAM were positively associated throughout young adulthood and interventions could target them in tandem, their associations with affect suggest differential etiologic processes. Preventive intervention and harm reduction efforts should attend to psychological context in which these behaviors occur.

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.

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.

Assessing the need for pre-mental health competencies in undergraduate education: insights from graduate faculty surveys.

Introduction: Despite the value of clinical competencies for masters- and doctoral-level practitioners as well as the tremendous variability in preparedness for graduate school and at graduation from graduate school, there are no competency standards for students pursuing mental healthcare careers prior to graduate study. This study aimed to identify potential pre-mental health competency standards for undergraduates pursuing mental healthcare careers. Methods: Faculty at masters and doctoral programs in a range of mental healthcare fields were asked to rate their expectations of entry-level competence and the perceived entry-level competence of their first-year, bachelor-level graduate students on 42 sub-competencies derived from the APA's Competency Benchmarks in Professional Psychology. Results: Faculty of both masters (N = 320) and doctoral (N = 220) programs reported high expectations of first-year graduate students for 11 competency categories (professional values/attitudes; relationships; management-administration; interdisciplinary systems; individual/cultural diversity; advocacy; scientific knowledge and methods; reflective practice, self-assessment, and self-care; ethical standards and policy; supervision, and research/evaluation) and 25 sub-competencies. Faculty in masters programs rated students as not meeting their expectations in 28 sub-competencies, while faculty in doctoral programs rated students as not meeting their expectations in 17 sub-competencies. Faculty recommended internships as well as improvement in writing, counseling skills, professional behavior, diversity, equity, and inclusion, cultural competence and humility, research methods, reading research, connecting research to practice, and education about the different mental healthcare professions. Discussion: Our findings suggest that students would benefit from intentional training in multiple pre-mental health competency areas at the undergraduate level to facilitate graduate-level training in mental healthcare and to better prepare our future clinicians.

Incompleteness of the large-N analysis of the O(N) models: Nonperturbative cuspy fixed points and their nontrivial homotopy at finite N.

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.

Using a modified Delphi process to explore international surgeon-reported benefits of robotic-assisted surgery to perform abdominal rectopexy.

BACKGROUND: Robotic-assisted surgery (RAS) offers improved visualisation and dexterity compared to laparoscopy. As a result, RAS is considered an attractive option for performing rectopexy, particularly in the confines of the lower pelvis. The aim of this study was to explore the benefits of RAS in rectopexy by analysing the views of a group of surgeons will have published on robotic rectopexy. METHODS: A three-round Delphi process was performed. Combined qualitative, Likert scale and binary responses were utilised in rounds one and two with binary responses seeking overall consensus in round two and three. Particular areas that were studied included: clinical aspects of patient selection, technical aspects of using RAS to perform rectopexy, ergonomic factors, training, and consideration of the 'learning-curve'. Consensus was defined as agreement > 80% among participants. Potential experienced RAS rectopexy surgeons were identified using PubMed where authors of studies reporting outcomes from RAS rectopexy were searched and invited. RESULTS: Twenty surgeons participated from the following countries: France, Germany, Ireland, Italy, Netherlands, Switzerland, UK, and USA. Participants had median operative experience of 75 (range 20-450) rectopexies (all techniques) and 11(range 0-300) robotic-rectopexies for all indications. All participants agreed that patient-reported functional outcomes and improved quality-of-life were the most important outcomes following rectopexy. Participants agreed the most significant benefits offered by RAS for rectopexy were improved precision due to better visualisation (80%), improved dexterity (90%) and improved overall accuracy e.g., for suture placement (90%). Ninety percent agreed that the superior ergonomics of RAS rectopexy improved their performance on several steps of the operation, in particular: mesh fixation (85%) and rectovaginal dissection (80%). Consensus on the learning curve for RAS abdominal rectopexy was not achieved: forty-five percent (n = 9) reported the learning curve as 11-20 cases and 55% (n = 11) as 21-30 cases. CONCLUSIONS: A panel of surgeons who had published on RAS view that it positively improves performance of rectopexy in terms of technical skills, improved dexterity and visualisation and ergonomics.

Value-based healthcare analysis of shoulder surgery for patients with symptomatic rotator cuff tears - Calculating the impact of arthroscopic cuff repair.

Background: Surgical repair of full-thickness rotator cuff tears in symptomatic patients is known to offer significant benefits. Despite this there remains a lack of universal appreciation that such surgery offers high clinical value, with some commissioners even limiting access to it. The value-based healthcare agenda provides a means to design, deliver and measure the impact of healthcare to a defined segment of patients. The aim of this study was to measure the value of surgically repairing primary symptomatic full-thickness rotator cuff tears when outcomes and costs were assessed over an entire care pathway. Methods: A prospective study of patients undergoing rotator cuff tears repair was undertaken. Patients were managed using a standardised integrated care pathway. Subsequent outcomes and costs were measured over the whole care pathway. Outcomes were assessed from both traditional and patient centric re-formatted prisms. Results: Significant improvement in clinical outcomes where recognised when assessed from either the traditional or re-formatted prisms. Economic review of this approach revealed the pathway generated a sustainable and notable positive margin. Discussion: This study evidences how a well-designed value-based healthcare shoulder approach can be delivered and measured. It demonstrates rotator cuff surgery to be a high value treatment for patients with symptomatic rotator cuff tears.

Movement ecology of vulnerable lowland tapirs between areas of varying human disturbance.

BACKGROUND: Animal movement is a key ecological process that is tightly coupled to local environmental conditions. While agriculture, urbanisation, and transportation infrastructure are critical to human socio-economic improvement, these have spurred substantial changes in animal movement across the globe with potential impacts on fitness and survival. Notably, however, human disturbance can have differential effects across species, and responses to human activities are thus largely taxa and context specific. As human disturbance is only expected to worsen over the next decade it is critical to better understand how species respond to human disturbance in order to develop effective, case-specific conservation strategies. METHODS: Here, we use an extensive telemetry dataset collected over 22 years to fill a critical knowledge gap in the movement ecology of lowland tapirs (Tapirus terrestris) across areas of varying human disturbance within three biomes in southern Brazil: the Pantanal, Cerrado, and Atlantic Forest. RESULTS: From these data we found that the mean home range size across all monitored tapirs was 8.31 km2 (95% CI 6.53-10.42), with no evidence that home range sizes differed between sexes nor age groups. Interestingly, although the Atlantic Forest, Cerrado, and Pantanal vary substantially in habitat composition, levels of human disturbance, and tapir population densities, we found that lowland tapir movement behaviour and space use were consistent across all three biomes. Human disturbance also had no detectable effect on lowland tapir movement. Lowland tapirs living in the most altered habitats we monitored exhibited movement behaviour that was comparable to that of tapirs living in a near pristine environment. CONCLUSIONS: Contrary to our expectations, although we observed individual variability in lowland tapir space use and movement, human impacts on the landscape also had no measurable effect on their movement. Lowland tapir movement behaviour thus appears to exhibit very little phenotypic plasticity in response to human disturbance. Crucially, the lack of any detectable response to anthropogenic disturbance suggests that human modified habitats risk being ecological traps for tapirs and this information should be factored into conservation actions and species management aimed towards protecting lowland tapir populations.

Prediction of autism spectrum disorder diagnosis using nonlinear measures of language-related EEG at 6 and 12 months.

BACKGROUND: Early identification of autism spectrum disorder (ASD) provides an opportunity for early intervention and improved developmental outcomes. The use of electroencephalography (EEG) in infancy has shown promise in predicting later ASD diagnoses and in identifying neural mechanisms underlying the disorder. Given the high co-morbidity with language impairment, we and others have speculated that infants who are later diagnosed with ASD have altered language learning, including phoneme discrimination. Phoneme learning occurs rapidly in infancy, so altered neural substrates during the first year of life may serve as early, accurate indicators of later autism diagnosis. METHODS: Using EEG data collected at two different ages during a passive phoneme task in infants with high familial risk for ASD, we compared the predictive accuracy of a combination of feature selection and machine learning models at 6 months (during native phoneme learning) and 12 months (after native phoneme learning), and we identified a single model with strong predictive accuracy (100%) for both ages. Samples at both ages were matched in size and diagnoses (n = 14 with later ASD; n = 40 without ASD). Features included a combination of power and nonlinear measures across the 10­20 montage electrodes and 6 frequency bands. Predictive features at each age were compared both by feature characteristics and EEG scalp location. Additional prediction analyses were performed on all EEGs collected at 12 months; this larger sample included 67 HR infants (27 HR-ASD, 40 HR-noASD). RESULTS: Using a combination of Pearson correlation feature selection and support vector machine classifier, 100% predictive diagnostic accuracy was observed at both 6 and 12 months. Predictive features differed between the models trained on 6- versus 12-month data. At 6 months, predictive features were biased to measures from central electrodes, power measures, and frequencies in the alpha range. At 12 months, predictive features were more distributed between power and nonlinear measures, and biased toward frequencies in the beta range. However, diagnosis prediction accuracy substantially decreased in the larger, more behaviorally heterogeneous 12-month sample. CONCLUSIONS: These results demonstrate that speech processing EEG measures can facilitate earlier identification of ASD but emphasize the need for age-specific predictive models with large sample sizes to develop clinically relevant classification algorithms.

Narrowband ultraviolet B phototherapy is associated with a reduction in topical corticosteroid and clinical improvement in atopic dermatitis: a historical inception cohort study.

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.

Urogenital function following robotic and laparoscopic rectal cancer surgery: meta-analysis.

BACKGROUND: Mixed results are reported on clinical and cancer outcomes in laparoscopic rectal cancer surgery (LRCS) compared with robotic rectal cancer surgery (RRCS). However, more favourable functional outcomes are reported following RRCS. This study compared urinary and sexual function following RRCS and LRCS in male and female patients. METHODS: A systematic review and meta-analysis of urinary and sexual function after RRCS and LRCS was performed following PRISMA and MOOSE guidelines, and registered prospectively with PROSPERO (ID:CRD42020164285). The functional outcome reporting tools most commonly included: the International Prostate Symptom Score (IPSS), International Index of Erectile Function (IIEF) and Female Sexual Function Index (FSFI). Mean scores and changes in mean scores from baseline were analysed using RevMan version 5.3. RESULTS: Ten studies were included reporting on 1286 patients. Some 672 patients underwent LRCS, of whom 380 (56.5 per cent) were men and 116 (17.3 per cent) were women (gender not specified in 176 patients, 26.2 per cent). A total of 614 patients underwent RRCS, of whom 356 (58.0 per cent) were men and 83 (13.5 per cent) were women (gender not specified in 175 patients, 28.5 per cent). Regarding urinary function in men at 6 months after surgery, IPSS scores were significantly better in the RRCS group than in the LRCS group (mean difference (MD) -1.36, 95 per cent c.i. -2.31 to -0.40; P = 0.005), a trend that persisted at 12 months (MD -1.08, -1.85 to -0.30; P = 0.007). ΔIIEF scores significantly favoured RRCS at 6 months [MD -3.11 (95%CI -5.77, -0.44) P <0.021] and 12 months [MD -2.76 (95%CI -3.63, -1.88) P <0.001] post-operatively. Mixed urinary and sexual function outcomes were reported for women. CONCLUSION: This meta-analysis identified more favourable urinary and erectile function in men who undergo robotic compared with conventional laparoscopic surgery for rectal cancer. Outcomes in women did not identify a consistently more favourable outcome in either group. As robotic rectal cancer surgery may offer more favourable functional outcomes it should be considered and discussed with patients.

Effect of 3 autumn pasture management strategies applied to 2 farm system intensities on the productivity of spring-calving, pasture-based dairy systems.

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.

Resource Use After Unwanted Sexual Experiences in Undergraduates: A Comprehensive Evaluation of Factors Related to the Decision to Seek Help.

The risk for sexual victimization in college is high, and although there can be significant mental and physical consequences for the survivor, resource utilization for this issue is extremely low. The current study used the frameworks of both the ecological model and the theory of planned behavior to examine factors related to resource use in undergraduate survivors of unwanted sexual experiences. The sample consisted of 217 undergraduates who reported at least one unwanted sexual experience while in college (89% female, 76.5% Caucasian, M age 19.6). Data were collected in an online survey from a private liberal arts college, and were analyzed using decision tree modeling. Results suggested that resource use was less related to demographic or event characteristics, but rather related to victim response to the event as well as perceptions about control over potential resource use. In addition to key assault prevention efforts, it is thus important to also support survivor mental health and self-efficacy postassault.

Undergraduates' Disclosures of Unwanted Sexual Experiences: Who, Why, and When?

This study evaluated patterns of sexual assault disclosures as well as the response and impact of that response on assault survivors. The sample consisted of 217 undergraduates with a history of sexual assault (89.5% female, 76.5% Caucasian). Participants reported the order in which they disclosed and the nature and impact of the response they received. Results indicated that the majority of participants told close peers first and perceived the first response to be supportive. These findings are encouraging but also demonstrate the need for improving the response that an assault survivor receives.

Spontaneous Escherichia coli Meningitis and Pyogenic Ventriculitis in an Adult Receiving Anti-Tumour Necrosis Factor Alpha Therapy.

Presentation A 60-year-old male taking etanercept for ankylosing spondylitis was admitted to hospital with confusion and reduced level of consciousness over the preceding 24 hours. Diagnosis Magnetic Resonance Imaging (MRI) of his brain revealed pyogenic ventriculitis, and Escherichia coli was cultured from CSF. Treatment He required placement of an external ventricular drain and was treated with a prolonged course of intravenous ceftriaxone. Conclusion To our knowledge, this is the first reported case of spontaneous Gram-negative bacillary meningitis in a patient on anti-tumour necrosis factor (TNF)-alpha therapy, highlighting the risk of rare but serious infections associated with this class of medication.

Randomized trial comparing low-pressure versus standard-pressure pneumoperitoneum in laparoscopic colectomy: PAROS trial.

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.

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.

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.

African histoplasmosis in a Guinea Bissau patient with HIV-2: Case report and review.

African histoplasmosis is the relatively unknown infection by Histoplasma capsulatum var. duboisii. It is endemic to Central and West Africa, generally involving the skin with potential for systemic dissemination, and has been described mainly in immunocompetent hosts. We present the case of a 30-year-old Bissau-Guinean man with HIV-2 infection known for 16 years, irregularly treated, admitted with two weeks of fever, diarrhoea and cutaneous lesions. Examination revealed multiple subcutaneous nodes, Molluscum contagiosum-like lesions, generalized lymphadenopathy and painful palpation of the left iliac fossa. Laboratory tests showed severe nonhaemolytic anaemia and CD4+ count of 9/mm3, with normal creatinine and hepatic enzymes. Chest roentgenogram was unremarkable and a research for Mycobacterium tuberculosis by GeneXpert® was negative. Nonetheless, given the lack of further diagnostic tools, a presumptive diagnosis of disseminated tuberculosis was made, and the patient was started on tuberculostatic and antiretroviral drugs. Despite initial improvement, a national shortage of antiretrovirals precluded further treatment, with worsening of the clinical picture, namely an increase in the number and dimensions of the skin lesions. An excisional biopsy of a subcutaneous nodule revealed Histoplasma capsulatum var. duboisii. Unfortunately, due to the unavailability of antifungals, the patient died one week later. To our best knowledge, this is the first confirmed case of an HIV infected patient with African histoplasmosis in Guinea-Bissau.
