Gender and Race/Ethnicity dynamics in anesthesiology mentorship: results of a European survey.

BACKGROUND: Mentorship is crucial to career advancement, medical education, and psychosocial support, especially for women and minorities. Although anesthesia mentoring programs have shown promise, there are no survey data regarding mentor-mentee relationship dynamics. This study aimed to explore the dynamics of the anesthesia mentor/mentee relationship. METHODS: A open cross-sectional web-based survey was distributed by the European Society of Anesthesiology and Intensive Care and European Society of Regional Anesthesia to European anesthesiologists. Participation was anonymous and consent was obtained. The study evaluated responses relating to preferences, facilitators, and barriers to mentorship relationships along with sociodemographic information. RESULTS: In total, 543 anesthesiologists responded to the survey, and 406 (111 mentees, 49 mentors, 193 both, 53 neither) responded to questions regarding mentorship. 184 anesthesiologists identified as woman and 22 as other genders (non-binary, transgender, gender-fluid, and self-described gender). Moreover, 250 anesthesiologists identified as white. Both mentors and mentees indicated that personal compatibility was the most important factor for successful mentorship. Barriers to mentorship included time consumption and perceived lack of interest from the mentor and mentee. Both mentors and mentees benefited from this relationship. The former reported feeling helpful, and the latter supported the development of clinical skills. The mentors indicated that their participation was important for protecting against burnout/exhaustion and impostor syndrome. Participants reported a preference for mentorship programs organized at the departmental level, offered at the start of the anesthesiology education curricula. Women were more likely to feel a 'lack of interest' in mentoring them as a barrier (OR = 2.49, P = 0.033). Gender was a barrier for mentors of other genders (OR = 23.9, P = 0.0027) and ethnicity (OR = 48.0, P = 0.0023). White mentees found gender (OR = 0.14, P = 0.021) and ethnicity (OR = 0.11, P = 0.048) to be less important barriers to successful mentorship relationship. CONCLUSION: When possible, programs should prioritize matching mentors and mentees based on personal compatibility and experience in the mentee's area of interest. Addressing the perceived lack of interest in mentoring is essential for promoting diversity, equality, and inclusion within anesthesiology, as well as and uplifting women and minorities.

Influence of the scanning path on the accuracy of intraoral scanners in the implanted edentulous patient: an in vitro study.

AIM: The aim of this in vitro study was to investigate the influence of scan paths on the accuracy (trueness and precision) of intra-oral scanning of an implant impression on an edentulous patient. MATERIAL AND METHODS: An epoxy resin maxillary model was made with 6 bone level implants (NobelParallel Conical Connection RP, NobelBiocare®). The implants were placed at the spot of the first incisor, the canine and the first molar. The trans gingival component (Multi-unit, NobelBiocare®) was screwed onto the implants. The scanbodies (IO 2C-A, Elos Accurate®) were then screwed onto the multi-units. The model was run through a coordinate measurement machine to obtain a control cast. Then, five different scanning paths, respectively the zigzag technique (ZZT), the zigzag technique with palatal (ZZTP), the wrap technique (WT), the wrap technique with palatal (WTP), and the big zigzag technique (BZZT), were applied by a single operator. Finally, each scan was compared to the control model. Results were assessed by one-way ANOVA and linear mixed effects models at P<0.05. RESULTS: The study showed that scan paths ZZT and ZZTP had significantly lower absolute positioning errors and residual mean square errors than the others (P<0.0001). For distances between consecutive implant axes and for absolute vertical errors, their superiority was borderline (P<0.10). Overall, techniques ZZT and ZZTP were equally performant and proved to be the most accurate. CONCLUSIONS: This in vitro experimental study demonstrates that the scan path can have an influence on the accuracy of the optical impression for full arch rehabilitation on implants.

Clinical usefulness of quantitative thermal sensory testing in the diagnosis and surgical treatment of women with pudendal neuropathy.

BACKGROUND: The aim of this study, conducted on women with pudendal neuropathy, was to evaluate the usefulness of quantitative thermal sensory testing (QTST) in the diagnosis, surgical management, and prognosis of the disease. METHODS: The study was conducted on 90 women with pudendal neuropathy. QTST in pudendal nerve sensory innervation territory was realized before and more than 24 months after operative pudendoscopy on most patients. Cold and warm thresholds were evaluated together with a search for qualitative anomalies. The diagnostic value of QTST was assessed by comparing baseline data with normative values previously derived from 41 presumably healthy women. The effect of operative pudendoscopy on thermal sensitivity was tested by comparing preoperative and postoperative measurements. Assessment of the long-term prognostic value of QTST was based on "surgical success" defined as a VAS pain level less than 4 at least 2 years after surgery. RESULTS: The existence of qualitative anomalies, like anesthesia, allodynia, dysesthesia, radiation, and dyslocalization, was clearly indicative of pudendal neuropathy. The presence of after sensation and "out of limit" values of skin temperature and cold detection threshold were also helpful for diagnosing the disease. Surgery reduced qualitative anomalies but had no positive effect on QTST thresholds. QTST measurements had no real prognostic value but other factors like constipation and abnormal perineal descent were predictive of surgical success. CONCLUSION: For women with pudendal neuropathy, QTST can be considered a useful, non-invasive tool in the diagnosis, and management of the disease, but it cannot predict satisfactorily long-term outcome of operative pudendoscopy.

Involvement of KCa3.1 channel activity in immediate perioperative cognitive and neuroinflammatory outcomes.

BACKGROUND: Potassium channels (KCa3.1; Kv1.3; Kir2.1) are necessary for microglial activation, a pivotal requirement for the development of Perioperative Neurocognitive Disorders (PNDs). We previously reported on the role of microglial Kv1.3 for PNDs; the present study sought to determine whether inhibiting KCa3.1 channel activity affects neuroinflammation and prevents development of PND. METHODS: Mice (wild-type [WT] and KCa3.1-/-) underwent aseptic tibial fracture trauma under isoflurane anesthesia or received anesthesia alone. WT mice received either TRAM34 (a specific KCa3.1 channel inhibitor) dissolved in its vehicle (miglyol) or miglyol alone. Spatial memory was assessed in the Y-maze paradigm 6 h post-surgery/anesthesia. Circulating interleukin-6 (IL-6) and high mobility group box-1 protein (HMGB1) were assessed by ELISA, and microglial activitation Iba-1 staining. RESULTS: In WT mice surgery induced significant cognitive decline in the Y-maze test, p = 0.019), microgliosis (p = 0.001), and increases in plasma IL-6 (p = 0.002) and HMGB1 (p = 0.001) when compared to anesthesia alone. TRAM34 administration attenuated the surgery-induced changes in cognition, microglial activation, and HMGB1 but not circulating IL-6 levels. In KCa3.1-/- mice surgery neither affected cognition nor microgliosis, although circulating IL-6 levels did increase (p < 0.001). CONCLUSION: Similar to our earlier report with Kv1.3, perioperative microglial KCa3.1 blockade decreases immediate perioperative cognitive changes, microgliosis as well as the peripheral trauma marker HMGB1 although surgery-induced IL-6 elevation was unchanged. Future research should address whether a synergistic interaction exists between blockade of Kv1.3 and KCa3.1 for preventing PNDs.

Widespread kidney anomalies in children with Down syndrome.

BACKGROUND: Rare autopsy studies have described smaller kidneys as well as urinary tract anomalies in Down syndrome. This observation has never been investigated in vivo and little is known about the possible consequences upon kidney function. Here we wish to confirm whether children with Down syndrome have smaller kidneys and to evaluate their kidney function in vivo. METHODS: This retrospective cohort study enrolled 49 children with Down syndrome, as well as 49 age- and sex-matched controls at the Queen Fabiola Children's University Hospital in Brussels, Belgium. Doppler and kidney ultrasonography, spot urine albumin to creatinine ratio, estimated glomerular filtration rate (eGFR), and anthropometric data were recorded. RESULTS: Kidney size in children with Down syndrome was smaller than age- and sex-matched controls in terms of length (p < 0.001) and volume (p < 0.001). Kidney function based on eGFR was also decreased in Down syndrome compared to historical normal. Twenty-one of the children with Down syndrome (42%) had eGFR < 90 mL/min/1.73 m2, with 5 of these (10%) having an eGFR < 75 mL/min/1.73 m2. In addition, 7 of the children with Down syndrome (14%) had anomalies of the kidney and/or urinary tract that had previously been undiagnosed. CONCLUSIONS: Children with Down syndrome have significantly smaller kidneys than age-matched controls as well as evidence of decreased kidney function. These findings, in addition to well-noted increased kidney and urologic anomalies, highlight the need for universal anatomical and functional assessment of all individuals with Down syndrome. A higher resolution version of the Graphical abstract is available as Supplementary information.

Outcomes and Predictors of Mortality in a Belgian Population of Patients Admitted with Ruptured Abdominal Aortic Aneurysm and Treated by Open Repair in the Contemporary Era.

BACKGROUND: Abdominal aortic aneurysm (AAA) rupture is a serious condition that results in extremely high mortality rates. Some improvements in outcome have been reported during the last 2 decades. The objective of the present study was to determine the overall and operative (by open repair) mortality related to ruptured AAA in the contemporary era and to identify preoperative, intraoperative, and early postoperative parameters associated with poor outcomes. METHODS: We performed a retrospective review of all consecutive patients admitted to our single institution with a diagnosis of ruptured AAA between 2004 and 2013. A total of 103 parameters, including demographic characteristics, medical history, clinical and biological parameters, cardiovascular risk factors, emergency level, diagnostic modalities, time from symptoms to diagnosis and treatment, type of operative procedure and postoperative complications, were analyzed. The primary endpoint considered in this study was the cumulative incidence rate of mortality. The secondary endpoint was the identification, by logistic regression methods, of risk factors for overall mortality as well as for operative, and postoperative mortality. RESULTS: Within our study period, 104 patients were admitted for a ruptured AAA. The majority of patients (84.6%) were male, and the AAA was known in 34.6% of the patients. Rupture occurred for a maximal diameter lower than 55 mm in 25% of the female population, compared to 5.7% of the male population (P = 0.030). The proportions of admitted patients who died before (preoperative mortality), during (intraoperative mortality) or after (postoperative hospital mortality) surgery was 17.3%, 16.3%, and 18.3%, respectively, yielding a cumulative in-hospital mortality of 51.9%. In the multivariate analysis, age ≥ 80 (P = 0.001), myocardial ischemia on the admission ECG (P = 0.046), and management by the physician response unit (P = 0.002) were the only preoperative parameters associated with a higher risk of hospital mortality. Four risk factors were found to be associated with a higher risk of postoperative mortality in the multivariate analysis, and all patients presenting with 3 or more of these risk factors (n = 5) died. CONCLUSIONS: The overall mortality of ruptured AAA in a contemporary cohort of patients who underwent open repair remains high and does not seem to have decreased during recent decades. Ruptures occur at smaller diameters in women than in men, supporting a lower threshold for intervention in women with known AAA. We developed risk scores to predict the mortality of patients with rAAA at different times of their hospital course. The validity of these scores should be assessed in prospective clinical studies.

Parental Perception of Body Weight Status of Their 8-year-old Children: Findings from the European CHOP Study.

BACKGROUND: Maternal perception of child weight status in children with overweight or obesity has received a lot of attention but data on paternal perception of children from presumably healthy cohorts are lacking. OBJECTIVE: We aimed to investigate paternal and maternal perception of child weight status at the age of 8 years in a cohort of 591 children from 5 European countries. MATERIAL AND METHODS: Included were 8-year-old children and their parents participating in the European Childhood Obesity Project (EU CHOP). Weight and height of children and parents were measured and Body Mass Index (BMI, kg/m2) was calculated. Both parents were asked to assess their perception of child weight status using Eckstein scales and their concern about child overweight. The agreement between mother and father perceptions was assessed by Cohen kappa coefficient and their relationship was analyzed by linear mixed effects models based on ordinal logistic regression, accounting for country, child gender and BMI, parental BMI, level of education, concern and type of feeding during first year of life. RESULTS: Data from children and both parents were available for 432 girls and boys. Mean BMI was comparable in boys and girls (16.7 ± 2.31 vs. 16.9 ± 2.87 kg/m2, P = 0.55). In total, 172 children (29.3%) were overweight or obese. There was a high degree of agreement between mother and father perceptions of their child's weight status (Cohen kappa 0.77). Multivariate modelling showed that perception levels significantly increased with child BMI but were globally lower than assessed. They differed between countries, gender and types of feeding during first year of life, were influenced by education level of the father but were not related to parental BMI and concern about childhood overweight. CONCLUSIONS: The study showed no overall differences between mothers and fathers in rating their child's weight status but both parents had a propensity to underestimate their child's actual weight, particularly in boys. The EU CHOP trial registered at clinicaltrials.gov as NCT00338689.

Curcuma longa and Boswellia serrata extract combination for hand osteoarthritis: an open-label pre-post trial.

CONTEXT: Osteoarthritis (OA) of the hand is a common painful musculoskeletal disorder with no cure. There is a need for an efficient and safe treatment to relieve OA pain. OBJECTIVE: To investigate the effects of a Curcuma longa and Boswellia serrata food supplement in addition to standard care on hand pain. MATERIALS AND METHODS: This open-label, non-controlled, post-observational study was based on 232 patients suffering from hand pain with or without joint deformity. Patients received a medical prescription for a three-month treatment with a food supplement containing 89 mg of C. longa dry extract, 120 mg of B. serrata resin, and 1.8 µg vitamin D. Pain was evaluated on a 10-point visual analog scale (VAS). The number of painful hand joints, patient satisfaction, nonsteroidal anti-inflammatory drugs intake, and side effects were also recorded. RESULTS: Baseline pain intensity (regression coefficient ± SE: -0.19 ± 0.01, p < 0.0001) and the number of painful joints (regression coefficient ± SE: -0.022 ± 0.0029, p < 0.0001) decreased significantly throughout the 3 months treatment period. NSAIDs intake and topical drug application were significantly decreased by 64% (p < 0.0001) and 79% (p < 0.0001) after 12 weeks, respectively. Only 3/239 (1.3%) patients reported side effects probably related to the product. 80.3% were satisfied with the treatment and 75.5% wished to continue treatment. CONCLUSION: This is the first clinical trial showing that C. longa and B. serrata resin can relieve symptoms in patients with hand osteoarthritis. The study provides useful information for the design of a clinical trial including a broader population.

Adenosine Diphosphate and the P2Y13 Receptor Are Involved in the Autophagic Protection of Ex Vivo Perfused Livers From Fasted Rats: Potential Benefit for Liver Graft Preservation.

Studies on how to protect livers perfused ex vivo can help design strategies for hepatoprotection and liver graft preservation. The protection of livers isolated from 24-hour versus 18-hour starved rats has been previously attributed to autophagy, which contributes to the energy-mobilizing capacity ex vivo. Here, we explored the signaling pathways responsible for this protection. In our experimental models, 3 major signaling candidates were considered in view of their abilities to trigger autophagy: high mobility group box 1 (HMGB1), adenosine monophosphate-activated protein kinase (AMPK), and purinergic receptor P2Y13. To this end, ex vivo livers isolated from starved rats were perfused for 135 minutes, after which perfusate samples were studied for protein release and biopsies were performed for evaluating signaling protein contents. For HMGB1, no significant difference was observed between livers isolated from rats starved for 18 and 24 hours at perfusion times of both 0 and 135 minutes. The phosphorylated and total forms of AMPK, but not their ratios, were significantly higher in 24-hour fasted than in 18-hour fasted livers. However, although the level of phosphorylated AMPK increased, perfusing ex vivo 18-hour fasted livers with 1 mM 5-aminoimidazole-4-carboxamide ribonucleotide, an AMPK activator, did not protect the livers. In addition, the adenosine diphosphate (ADP; and not adenosine monophosphate [AMP]) to AMP + ADP + adenosine triphosphate ratio increased in the 24-hour starved livers compared with that in the 18-hour starved livers. Moreover, perfusing 24-hour starved livers with 0.1 mM 2-[(2-chloro-5-nitrophenyl)azo]-5-hydroxy-6-methyl-3-[(phosphonooxy)methyl]-4-pyridinecarboxaldehyde (MRS2211), a specific antagonist of the P2Y13 receptor, induced an increase in cytolysis marker levels in the perfusate samples and a decrease in the levels of autophagic marker microtubule-associated proteins 1 light chain 3 II (LC3II)/actin (and a loss of p62/actin decrease), indicating autophagy inhibition and a loss of protection. The P2Y13 receptor and ADP (a physiological activator of this receptor) are involved in the protection of ex vivo livers. Therapeutic opportunities for improving liver graft preservation through the stimulation of the ADP/P2Y13 receptor axis are further discussed.

Effects of Bifidobacterium longum BB536 and Lactobacillus rhamnosus HN001 in IBS patients.

BACKGROUND: Irritable bowel syndrome (IBS) is a common gastrointestinal disorder, which still lacks effective therapy. We aimed to investigate the effects of a novel formulation of Bifidobacterium longum BB536 and Lactobacillus rhamnosus HN001 with vitamin B6 (LBB) on symptoms, intestinal permeability, cultivable bacteria and metabolome in IBS subjects. MATERIALS AND METHODS: Twenty-five IBS patients (Rome IV criteria) (M:F = 8:17; age 48 years ± 11 SD) were randomized to treatment (LBB) or placebo (one month each) in a crossover randomized double-blind controlled trial. Symptoms, intestinal habits, disease severity, intestinal permeability and intestinal microbiota were analysed at 0, 30, 45 and 60 days. RESULTS: Percentage decrease from baseline of abdominal pain (-48.8% vs -3.5%), bloating (-36.35% vs +7.35%) and severity of disease (-30.1% vs -0.4%) was significantly (P < .0001) greater with LBB than placebo, respectively. In IBS-D patients, the improvement from baseline of Bristol score was more consistent with LBB (from 6 ± 0.4 to 4.3 ± 1.1, P < .00001) than placebo (from 6.2 ± 0.7 to 5.3 ± 1.1, P = .04). In IBS-C patients, Bristol score tended to improve from baseline after LBB (2.6 ± 1.1 vs 3.2 ± 0.5, P = .06). LBB significantly improved the percentage of sucralose recovery (colonic permeability) (1.86 ± 0.1 vs 1.1 ± 0.2, P = .01). During treatment, presumptive lactic acid bacteria and bifidobacteria, relative abundance of propanoic, butanoic, pentanoic acids and hydrocarbons increased, while phenol decreased. CONCLUSIONS: The novel formulation of B. longum BB536 and L. rhamnosus HN001 with B6 vitamin improves symptoms and severity of disease, restores intestinal permeability and gut microbiota in IBS patients.

Preoperative sedentary behavior is neither a risk factor for perioperative neurocognitive disorders nor associated with an increase in peripheral inflammation, a prospective observational cohort study.

BACKGROUND: Surgical interventions result in a postoperative rise in circulating inflammatory cytokines and high molecular group box protein 1 (HMGB1). Herein, the impact of a sedentary lifestyle and other age-related factors on the development of perioperative neurocognitive disorders (PND) following non-cardiac surgical procedures was assessed in an older (55-75 years-old) surgical population. METHODS: Prior to surgery, patients were asked questions regarding their sedentary behavior and daily habits. They also passed the Mini Mental State Examination (MMSE) and their blood circulating interleukin 6 (IL-6) and HMGB1 levels were assayed by ELISA. IL-6 and HMGB1 measurements were repeated respectively 6 and 24 h after surgery. MMSE was re-evaluated 6 weeks and whenever possible 3 months after surgery. RESULTS: Thirty-eight patients were enrolled in the study from January until July 2019. The study identified self-sufficiency, multilinguism, and overall health score on the geriatric depression scale, as protectors against PND. No other demographic (age, sex), environmental (solitary/non-solitary housing, professional and physical activities, smoking, alcohol drinking), comorbidity (antipsychotic drug uptake, diabetic state) and type of surgery (orthopedic, general, genitourinary) influenced the development of PND. Although some factors (surgery type and age) influenced the surgery-induced rise in the circulating IL-6 levels, they did not impact HMGB1. CONCLUSION: Inflammaging, reflected by the greater increment of surgery-induced IL-6 in patients with advanced age, was present. As trauma-induced release of HMGB1 was not similarly affected by age, we surmise that HMGB1, rather than circulating cytokines, is the key driver of the trauma-induced inflammatory cascade leading to PND.

Facteurs associés à la survie en milieu pénitentiaire : étude en République démocratique du Congo.

OBJECTIVE: The objective of this study was to identify factors associated with survival among prisoners at Mbuji-Mayi Central Prison, in Democratic Republic of Congo between January 2014 and December 2016. METHODS: This is a retrospective cohort study. The mortality rate was calculated during the 3-year follow-up period and the Kaplan-Meier survival curve was determined. Cox regression and risk ratio (HR) were used to analyze and quantify factors associated with survival. The study involved a total of 793 inmates. RESULTS: The average age of inmates was 33 ± 10 years (extremes: 17-67 years). The median follow-up time was 12 months for a total of 7,513 person-months. The number of deaths recorded was 135, for a mortality rate of 17.9/1,000 person-months. Risk factors associated with death were malnutrition (HR = 17.5; 95% CI = [12.1; 25.4]) and tuberculosis (HR = 11.8; 95% CI = [7.7; 17.8]). CONCLUSION: This study highlights a high rate of deaths in prisons and identifies the two potential factors (malnutrition and tuberculosis) that prison and health authorities need to address.

Piezocision-assisted orthodontic treatment using CAD/CAM customized orthodontic appliances: a randomized controlled trial in adults.

OBJECTIVE: The aim of this study was to investigate the effects of piezocision (surgical protocol with sutures) in orthodontic treatment using CAD/CAM (computer-aided design and computer-aided manufacturing) customized orthodontic appliances. DESIGN: The study is designed as a parallel group, randomized controlled trial (RCT). SETTING: University Hospital. ETHICAL APPROVAL: The study was approved by the ethic committee of the University Hospital Liege, Belgium. SUBJECTS AND METHODS: This RCT was conducted on 24 adult patients requiring orthodontic treatment to release mild overcrowding. Patients were all treated with a customized appliance and randomly assigned by means of sealed envelopes containing group codes to either a test group treated with piezocision or a control group without any further treatment. A blinded orthodontist validated appliance removal or further adjustments based on the model study. OUTCOME MEASURES: The overall treatment time and the time between archwire changes were recorded. Moreover, clinical and radiological features such as tooth resorption, gingival recessions, and the presence of scars were evaluated. RESULTS: A total of 24 patients (12 control and 12 test) completed the study. The overall treatment time was significantly shorter in the test group than the control group. Likewise, the time difference between all arch changes was significantly lower when piezocision was performed, except for the first arch at the mandible and the last arches at both maxillae. During the fine-tuning phase, no significant difference was found between the two groups. All periodontal and radiographic parameters remained stable from the start to the end of treatment in both the groups. However, minor scars were found in 66 per cent cases. LIMITATIONS: This trial was a single-centre trial. CONCLUSIONS: Piezocision seems to be an effective method to accelerate orthodontic treatment in cases of mild overcrowding. However, the effect was only observed during the alignment phase and a greater efficiency was found in the maxilla. The technique may be contraindicated in patients with a high smile line since the risk of slight scarring exists. REGISTRATION: ClinicalTrails.gov (Identifier: NCT03406130).

Contextual factors influence work outcomes in employed patients with ankylosing spondylitis starting etanercept: 2-year results from AS@Work.

Objectives: The aim was to determine changes over time in work outcomes and investigate the predictive value of baseline personal and work-related factors on the evolution of work outcomes among employed patients with AS initiating etanercept. Methods: Employment status, absenteeism and presenteeism were assessed using the Work Productivity and Activity Impairment for AS questionnaire in a 24-month open-label, observational study (NCT01421303). The potential effect of baseline factors on work outcomes was analysed using predictive modelling (Cox regression and linear mixed models). Results: After 24 months, 11/75 (14.7%) patients had permanently withdrawn from employment (seven because of AS). Absenteeism and presenteeism decreased significantly within 6 months of etanercept treatment and remained stable thereafter. Predictive modelling indicated that male sex (hazard ratio = 0.18; 95% CI: 0.04, 0.85), (log) number of working hours per week (hazard ratio = 0.13; 95% CI: 0.03, 0.51) and the possibility of developing skills (hazard ratio = 0.42; 95% CI: 0.19, 0.91) positively influenced time in employment. Over time, lower absenteeism was significantly associated with the quality of contact with colleagues [coefficient (s.e.): -0.35 (0.10)] and importance of the job for quality of life [-0.49 (0.17)], and higher absenteeism with current smoking [1.66 (0.44)] and change in job because of illness [1.51 (0.66)]. Over time, lower presenteeism was associated with male sex [-14.5 (2.64)], the possibility of postponing work [-6.60 (2.73)], quality of contact with colleagues [-2.04 (0.96)] and >50 workers in the company [-7.65 (2.76)], and higher presenteeism with manual profession [8.41 (2.72)]. Conclusion: Contextual factors influence work outcomes over time and should not be ignored when aiming to improve work outcomes in patients with AS.

FDG PET/CT radiomics for predicting the outcome of locally advanced rectal cancer.

PURPOSE: The aim of this study was to investigate the prognostic value of baseline 18F-FDG PET/CT textural analysis in locally-advanced rectal cancer (LARC). METHODS: Eighty-six patients with LARC underwent 18F-FDG PET/CT before treatment. Maximum and mean standard uptake values (SUVmax and SUVmean), metabolic tumoral volume (MTV), total lesion glycolysis (TLG), histogram-intensity features, as well as 11 local and regional textural features, were evaluated. The relationships of clinical, pathological and PET-derived metabolic parameters with disease-specific survival (DSS), disease-free survival (DFS) and overall survival (OS) were assessed by Cox regression analysis. Logistic regression was used to predict the pathological response by the Dworak tumor regression grade (TRG) in the 66 patients treated with neoadjuvant chemoradiotherapy (nCRT). RESULTS: The median follow-up of patients was 41 months. Seventeen patients (19.7%) had recurrent disease and 18 (20.9 %) died, either due to cancer progression (n = 10) or from another cause while in complete remission (n = 8). DSS was 95% at 1 year, 93% at 2 years and 87% at 4 years. Weight loss, surgery and the texture parameter coarseness were significantly associated with DSS in multivariate analyses. DFS was 94 % at 1 year, 86 % at 2 years and 79 % at 4 years. From a multivariate standpoint, tumoral differentiation and the texture parameters homogeneity and coarseness were significantly associated with DFS. OS was 93% at 1 year, 87% at 2 years and 79% after 4 years. cT, surgery, SUVmean, dissimilarity and contrast from the neighborhood intensity-difference matrix (contrastNGTDM) were significantly and independently associated with OS. Finally, RAS-mutational status (KRAS and NRAS mutations) and TLG were significant predictors of pathological response to nCRT (TRG 3-4). CONCLUSION: Textural analysis of baseline 18F-FDG PET/CT provides strong independent predictors of survival in patients with LARC, with better predictive power than intensity- and volume-based parameters. The utility of such features, especially coarseness, should be confirmed by larger clinical studies before considering their potential integration into decisional algorithms aimed at personalized medicine.

Endoscopic transperineal pudendal nerve decompression: operative pudendoscopy.

BACKGROUND: Pudendal nerve entrapment can produce a pudendal syndrome comprising perineodynia together with urinary, sexual, and anorectal symptoms. This syndrome can be treated surgically by the transperineal approach. By using an endoscope during the procedure ("operative pudendoscopy"), the surgeon has close-up visual control of each decompression steps, demonstrates the different levels of entrapment, and cuts the sacrospinous ligament under visual control. The aim of this study was to describe the technical details of this new technique and its outcome in the treatment of the pudendal syndrome. METHODS: A series of 113 patients with severe pudendal syndrome underwent operative pudendoscopy. A complete history, pain visual analog scale (VAS) for perineodynia, and four scores evaluating the main symptoms (ICIQ-SF, NHI-CPSI, St Mark's, and Wexner) were obtained before and at least 24 months after surgery. The three clinical signs of pudendal syndrome (abnormal pinprick sensitivity, painful skin rolling test, and painful pudendal nerve) and perineal descent were analyzed before and after surgery in 91 patients. RESULTS: The mean operating time per side was 50.3 ± 15.2 min and the average hospital stay was 2.1 ± 0.4 days. Perineodynia VAS dropped from 7.2 ± 1.4 to 4.5 ± 2.9 after surgery (p < 0.0001) and the symptoms scores significantly improved. Frequency of sexual arousal syndrome, dyspareunia, and cystalgia was also significantly reduced. Pathological perineal descent (≥ 1.5 cm measured with a Perineocaliper®) observed in 13 patients was reduced from 1.81 to 0.77 cm after surgery (p < 0.0001). The only significant complication was severe hemorrhage in one patient induced by an inferior gluteal vessel laceration and successfully treated by arterial embolization. CONCLUSIONS: A complete pudendal nerve decompression, from the distal branches to the sacral foramina, safely performed under visual control by using operative pudendoscopy markedly improves clinical signs and symptoms of the pudendal syndrome.

Heterogeneity of estrogen receptor α and progesterone receptor distribution in lesions of deep infiltrating endometriosis of untreated women or during exposure to various hormonal treatments.

Deep infiltrating endometriosis (DIE) responds variably to hormonal therapy. Mutations in cancer driver genes have been identified in a fraction of the ectopic endometrial epithelial cells, suggesting a functional heterogeneity of these lesions. To evaluate the phenotype heterogeneity of cells in DIE, we measured the expression of estrogen receptor α (ERα) and of progesterone receptor (PR) in DIE of untreated women or under various treatments. We analyzed the luminal epithelial height (LEH), immunoreactive epithelial staining (IRS) and stromal staining intensity (SSI) of ERα and PR. We observed a high variability in the same gland, among distinct glands in the same sample and among distinct patients receiving the same treatment. LEH variability was primarily due to epithelial cells heterogeneity in a gland, secondarily to the glands randomly evaluated on the same section, and tertiary to the patient category. Variability in IRS and SSI scores was primarily the consequence of their heterogeneity in the same woman and to a lesser extent to variability among patients. LEH and SSI were not modified according to treatment. IRS for PR was lower in treated patients. This heterogeneity of ERα and PR distribution could explain why endocrine treatments are unable to cure this condition.

Humor Associated With Positive Outcomes in Individual Psychotherapy.

Considerable anecdotal evidence points to the usefulness of humor in the therapeutic process, but empirical evidence is lacking. The purpose of this study, conducted in Belgium, was to search for an association between humor and therapy outcomes in a population of 110 adult psychotherapy clients who attended at least 10 therapy sessions. Clients and their therapist evaluated the frequency and intensity of humorous events, as well as therapy effectiveness, therapeutic alliance, perceived hope, and pleasure in participating in therapy sessions. A strong positive correlation was observed between humor and therapy effectiveness, from both client (rs=0.40; p<0.001) and therapist perspectives (rs=0.37; p<0.001). The link between humor and therapy effectiveness remained significant in subgroups of clients with more severe illness, although these clients reported less humor in their therapy sessions. Further research is needed to determine whether humor enhances outcomes or whether positive outcomes trigger occurrence of humor.
