Screening for precancerous anal lesions linked to human papillomaviruses: French recommendations for clinical practice.

In France, about 2000 new cases of anal cancer are diagnosed annually. Squamous cell carcinoma is the most common histological type, mostly occurring secondary to persistent HPV16 infection. Invasive cancer is preceded by precancerous lesions. In addition to patients with a personal history of precancerous lesions and anal cancer, three groups are at very high risk of anal cancer: (i) men who have sex with men and are living with HIV, (ii) women with a history of high-grade squamous intraepithelial lesions (HSILs) or vulvar HPV cancer, and (iii) women who received a solid organ transplant more than 10 years ago. The purpose of screening is to detect HSILs so that they can be treated, thereby reducing the risk of progression to cancer. All patients with symptoms should undergo a proctological examination including standard anoscopy. For asymptomatic patients at risk, an initial HPV16 test makes it possible to target patients at risk of HSILs likely to progress to cancer. Anal cytology is a sensitive test for HSIL detection. Its sensitivity is greater than 80% and exceeds that of proctological examination with standard anoscopy. It is indicated in the event of a positive HPV16 test. In the presence of cytological abnormalities and/or lesions and a suspicion of dysplasia on clinical examination, high-resolution anoscopy is indicated. Performance is superior to that of proctological examination with standard anoscopy. However, this technique is not widely available, which limits its use. If high-resolution anoscopy is not possible, screening by a standard proctological examination is an alternative. There is a need to develop high-resolution anoscopy and triage tests and to evaluate screening strategies.

French multicentre prospective evaluation of radiofrequency ablation in the management of haemorrhoidal disease.

PURPOSE: The aim of this study was to evaluate the efficacy and safety of radiofrequency ablation (RFA) in the management of haemorrhoidal disease with 1 year's follow-up. METHOD: This prospective multicentre study assessed RFA (Rafaelo©) in outpatients with grade II-III haemorrhoids. RFA was performed in the operating room under locoregional or general anaesthesia. Primary endpoint was the evolution of a quality-of-life score adapted to the haemorrhoid pathology (HEMO-FISS-QoL) 3 months after surgery. Secondary endpoints were evolution of symptoms (prolapsus, bleeding, pain, itching, anal discomfort), complications, postoperative pain and medical leave. RESULTS: A total of 129 patients (69% men, median age 49 years) were operated on in 16 French centres. Median HEMO-FISS-QoL score dropped significantly from 17.4/100 to 0/100 (p < 0.0001) at 3 months. At 3 months, the rate of patients reporting bleeding (21% vs. 84%, p < 0.001), prolapse (34% vs. 91.3%, p < 0.001) and anal discomfort (0/10 vs. 5/10, p < 0.0001) decreased significantly. Median medical leave was 4 days [1-14]. Postoperative pain was 4/10, 1/10, 0/10 and 0/10 at weeks 1, 2, 3 and 4. Seven patients (5.4%) were reoperated on by haemorrhoidectomy for relapse, and three for complications. Reported complications were haemorrhage (3), dysuria (3), abscess (2), anal fissure (1), external haemorrhoidal thrombosis (10), pain requiring morphine (11). Degree of satisfaction was high (+ 5 at 3 months on a - 5/+ 5 scale). CONCLUSION: RFA is associated with an improvement in quality of life and symptoms with a good safety profile. As expected for minimally invasive surgery, postoperative pain is minor with short medical leave. CLINICAL TRIAL REGISTRATION AND DATE: Clinical trial NCT04229784 (18/01/2020).

Management of perianal fistulas in Crohn's disease: a 2021 update of the French National Society of Coloproctology consensus.

BACKGROUND: Since our last publication of algorithms for the management of perianal fistulas in patients with Crohn's disease, researchers have proposed a treat to target strategy systematic combotherapy for anal lesions, and indications for stem cell injection. In the absence robust publications, the Société Nationale Française de Coloproctologie (French National Society of Coloproctology [SNFCP]) wished to establish a group consensus using the Delphi method. METHODS: From October 2020 to January 2021, a scientific committee and panel of gastroenterologists and surgeons established answers which were submitted to the members of the SNFCP during a national conference in November 2020. Three questions were clarified and reformulated, and then submitted during a third and final round of consultation of members of the SNFCP. RESULTS: The target was defined as being the response obtained in every domain (symptoms, physical and radiological evaluation) which could be considered satisfactory, without the need to intensify therapeutic management. By consensus, the time required for clinical evaluation of the efficacy of treatment was 6 months. A response on magnetic resonance imaging (MRI) should include the absence of a collection of 10 mm or more in size at 6 months, and a frank decrease or complete disappearance of hyperintensity in T1 and T2 sequences of the main tract at 12 months. Systematic association of an immunosuppressant with tumor necrosis factor inhibitors did not reach the consensus level for adalimumab (50%), but just did for infliximab (70%). The majority of the respondents considered failure of one, or even two lines of different biotherapies to be potential indications for injection of stem cells. CONCLUSIONS: These findings reinforce the importance of composite targets including MRI evaluation, and underscore the need for precise timing of evaluation. Combotherapy is only recommended with infliximab. Injection of stem cells is a second- or third-line option.

Assessment of sexual dysfunction in patients with perianal Crohn's disease.

AIM: Over the past 10 years, several studies have focused on sexuality in patients with Crohn's disease. Very few of them specifically focused on perianal disease (PD). This study aimed to compare the prevalence of sexual dysfunction (SD) in Crohn's disease patients with active PD versus controls without active PD. METHOD: Patients from 14 French centres with active PD, defined by the presence of symptomatic ulceration, fistula or stenosis, were arbitrarily included. They were compared with controls from the existing SEXIA cohort. Men completed the International Index of Erectile Function (IIEF) and women the Female Sexual Function Index (FSFI). The primary end-point was SD defined by FSFI < 26.55 in women and IIEF < 42.9 in men. RESULTS: Ninety-seven patients (64 women, 33 men) and 238 controls (131 women, 107 men) were included. SD was found in 66% of the female patients versus 50% of the controls (P = 0.04). In the male population, SD was found in 30% of the cases versus 16% of the controls (P = 0.06). Erectile dysfunction affected 46% of the male patients and 43% of the controls (P = 0.8). On multivariate analysis, the predictive factor most strongly associated with SD in women was severely active anal PD defined by a perineal disease activity index > 4 [OR = 13.05 (2.32-73.44)]. CONCLUSION: Women with active PD had an increased prevalence of SD compared with controls without active PD. In the male population, the study was unable to determine whether there was a difference as it was underpowered.

Is sitting time leading to mobility decline in long-term care residents?

BACKGROUND: Little is known about the sitting time in long-term care (LTC) facilities, or if sedentary behaviour affects changes in mobility over time. AIMS: The objectives were to document the sitting time of LTC residents and to examine if sitting time could predict changes in mobility. METHODS: Twenty residents of an LTC facility, representing three mobility statuses (independent, assisted transfer, and dependent transfer) were included. Sitting time was defined using an ActivPAL. Mobility statuses were reviewed 12 months later. RESULTS: Participants spent an average of 21.9 h per day sedentary. At follow-up, five residents experienced a decline in mobility status, but no baseline sitting time variables were associated with the changes in mobility status (P > 0.05). DISCUSSION/CONCLUSION: People living in LTC are highly sedentary. Sitting time differs amongst the mobility statues, but is unable to predict upcoming changes in mobility status.

Psychometric properties of a questionnaire (HEMO-FISS-QoL) to evaluate the burden associated with haemorrhoidal disease and anal fissures.

AIM: Current questionnaires designed to evaluate the burden of haemorrhoidal disease ignore symptoms such as bleeding, pain and itching. A specific questionnaire is needed to evaluate the global impact of anal disorders on patients' daily lives. METHOD: We developed a questionnaire (HEMO-FISS-QoL) to assess the symptom burden of anal disorders and administered it to 256 patients (mean age 46.2 years; men 60.4%) with haemorrhoidal disease (67.2%), anal fissure (29.3%) or both (3.5%). Psychometric properties were evaluated by testing the acceptability, construct validity and reliability of the questionnaire. Principal components and multi-trait analyses were used to identify dimensions and to assess construct validity. Backward Cronbach alpha curves and a graded response model were used to reduce the number of items and modalities. External validity was evaluated against SF-12 and the Psychological Global Well-Being Index (PGWBI) using Spearman's correlation coefficient. RESULTS: Principal component analysis defined four dimensions: physical disorders, psychology, defaecation and sexuality. The number of questions was reduced from 38 to 23. The HEMO-FISS-QoL scores correlated well with those of the SF-12 and PGWBI (P < 0.001). Cronbach's coefficients (all > 0.7) reflected good internal reliability of the different dimensions. The total score increased with the severity of the anal disorders and with their consequences (days off work and personal spending related to the disease). CONCLUSION: The HEMO-FISS-QoL questionnaire reliably evaluates the global impact of haemorrhoids and anal fissures on patients' daily lives. This simple tool may prove useful for treatment evaluation in clinical trials and daily practice.

How to manage anal ulcerations and anorectal stenosis in Crohn's disease: algorithm-based decision making : French National Working Group Consensus 2018.

The French National Society of Coloproctology established national recommendations for the treatment of anoperineal lesions associated with Crohn's disease. Treatment strategies for anal ulcerations and anorectal stenosis are suggested. Recommendations have been graded following international recommendations, and when absent professional agreement was established. For each situation, practical algorithms have been drawn.

Effect of an acute exercise bout on immediate post-exercise irisin concentration in adults: A meta-analysis.

Irisin is a recently discovered myokine that increases adipocyte metabolism, induces further "browning" of white adipose tissue, and enhances glucose metabolism. No study has ever determined how an acute bout of exercise impacts immediate post-exercise irisin concentration using a meta-analytic approach. The purpose of this study is to determine the impact of an acute bout of exercise on the magnitude of post-exercise irisin concentration in adults using meta-analytic procedures. Searches were performed on PubMed, EMBASE, CINAHL, PEDro, SCOPUS, and SPORTDiscus databases. Effect summaries were obtained using random-effects models. Random-effects single and multiple meta-regressions were performed to determine relationships between, and potential confounding effects of, variables of interest. Ten articles were retained for the final meta-analysis, producing 21 study estimates. An acute bout of exercise was accompanied by a post-exercise average increase in irisin concentration of 15.0 (95% CI: 10.8%-19.3%). There was no significant relationship between post-exercise irisin concentration and age, intensity of aerobic exercise, or type of exercise training session (resistance vs aerobic training). Fitness level and body mass index were identified as significant predictive variables for post-exercise irisin concentration. However, a multiple meta-regression model identified fitness level as the single best predictor, with being fit (21.1%±2.2%) associated with a nearly twofold increase in post-exercise irisin concentration, compared with being unfit (11.8%±2.1%). Immediately following an acute bout of exercise, irisin concentration increases substantially in adults, with fitness level as an important modifier for the effect.

Sensitivity assessment of sea lice to chemotherapeutants: Current bioassays and best practices.

Traditional bioassays are still necessary to test sensitivity of sea lice species to chemotherapeutants, but the methodology applied by the different scientists has varied over time in respect to that proposed in "Sea lice resistance to chemotherapeutants: A handbook in resistance management" (2006). These divergences motivated the organization of a workshop during the Sea Lice 2016 conference "Standardization of traditional bioassay process by sharing best practices." There was an agreement by the attendants to update the handbook. The objective of this article is to provide a baseline analysis of the methodology for traditional bioassays and to identify procedures that need to be addressed to standardize the protocol. The methodology was divided into the following steps: bioassay design; material and equipment; sea lice collection, transportation and laboratory reception; preparation of dilution; parasite exposure; response evaluation; data analysis; and reporting. Information from the presentations of the workshop, and also from other studies, allowed for the identification of procedures inside a given step that need to be standardized as they were reported to be performed differently by the different working groups. Bioassay design and response evaluation were the targeted steps where more procedures need to be analysed and agreed upon.

Management of anoperineal lesions in Crohn's disease: a French National Society of Coloproctology national consensus.

The French National Society of Coloproctology established national recommendations for the treatment of anoperineal lesions associated with Crohn's disease. Treatment strategies for acute abscesses, active fistulas (active denovo and still active under treatment), fistulas in remission, and rectovaginal fistulas are suggested. Recommendations have been graded following the international recommendations, and when absent, professional agreement has been established. For each situation, practical algorithms have been drawn.

Process efficiency of casein separation from milk using polymeric spiral-wound microfiltration membranes.

Microfiltration is largely used to separate casein micelles from milk serum proteins (SP) to produce a casein-enriched retentate for cheese making and a permeate enriched in native SP. Skim milk microfiltration is typically performed with ceramic membranes and little information is available about the efficiency of spiral-wound (SW) membranes. We determined the effect of SW membrane pore size (0.1 and 0.2 µm) on milk protein separation in total recirculation mode with a transmembrane pressure gradient to evaluate the separation efficiency of milk proteins and energy consumption after repeated concentration and diafiltration (DF). Results obtained in total recirculation mode demonstrated that pore size diameter had no effect on the permeate flux, but a drastic loss of casein was observed in permeate for the 0.2-µm SW membrane. Concentration-DF experiments (concentration factor of 3.0× with 2 sequential DF) were performed with the optimal 0.1-µm SW membrane. We compared these results to previous data we generated with the 0.1-µm graded permeability (GP) membrane. Whereas casein rejection was similar for both membranes, SP rejection was higher for the 0.1-µm SW membrane (rejection coefficient of 0.75 to 0.79 for the 0.1-µm SW membrane versus 0.46 to 0.49 for the GP membrane). The 0.1-µm SW membrane consumed less energy (0.015-0.024 kWh/kg of permeate collected) than the GP membrane (0.077-0.143 kWh/kg of permeate collected). A techno-economic evaluation led us to conclude that the 0.1-µm SW membranes may represent a better option to concentrate casein for cheese milk; however, the GP membrane has greater permeability and its longer lifetime (about 10 yr) potentially makes it an interesting option.

Anoperineal lesions in Crohn's disease: French recommendations for clinical practice.

BACKGROUND: Anoperineal lesion (APL) occurrence is a significant event in the evolution of Crohn's disease (CD). Management should involve a multidisciplinary approach combining the knowledge of the gastroenterologist, the colorectal surgeon and the radiologist who have appropriate experience in this area. Given the low level of evidence of available medical and surgical strategies, the aim of this work was to establish a French expert consensus on management of anal Crohn's disease. These recommendations were led under the aegis of the Société Nationale Française de Colo-Proctologie (SNFCP). They report a consensus on the management of perianal Crohn's disease lesions, including fistulas, ulceration and anorectal stenosis and propose an appropriate treatment strategy, as well as sphincter-preserving and multidisciplinary management. METHODOLOGY: A panel of French gastroenterologists and colorectal surgeons with expertise in inflammatory bowel diseases reviewed the literature in order to provide practical management pathways for perianal CD. Analysis of the literature was made according to the recommendations of the Haute Autorité de Santé (HAS) to establish a level of proof for each publication and then to propose a rank of recommendation. When lack of factual data precluded ranking according to the HAS, proposals based on expert opinion were written. Therefore, once all the authors agreed on a consensual statement, it was then submitted to all the members of the SNFCP. As initial literature review stopped in December 2014, more recent European or international guidelines have been published since and were included in the analysis. RESULTS: MRI is recommended for complex secondary lesions, particularly after failure of previous medical and/or surgical treatments. For severe anal ulceration in Crohn's disease, maximal medical treatment with anti-TNF agent is recommended. After prolonged drainage of simple anal fistula by a flexible elastic loop or loosely tied seton, and after obtaining luminal and perineal remission by immunosuppressive therapy and/or anti-TNF agents, the surgical treatment options to be discussed are simple seton removal or injection of the fistula tract with biological glue. After prolonged loose-seton drainage of the complex anal fistula in Crohn's disease, and after obtaining luminal and perineal remission with anti-TNF ± immunosuppressive therapy, surgical treatment options are simple removal of seton and rectal advancement flap. Colostomy is indicated as a last option for severe APL, possibly associated with a proctectomy if there is refractory rectal involvement after failure of other medical and surgical treatments. The evaluation of anorectal stenosis of Crohn's disease (ARSCD) requires a physical examination, sometimes under anesthesia, plus endoscopy with biopsies and MRI to describe the stenosis itself, to identify associated inflammatory, infectious or dysplastic lesions, and to search for injury or fibrosis of the sphincter. Therapeutic strategy for ARSCD requires medical-surgical cooperation.

The outcome of fistulotomy for anal fistula at 1 year: a prospective multicentre French study.

AIM: The study aimed to evaluate outcome at 1 year of one- and two-stage fistulotomy for anal fistula in a large group of patients. METHOD: A prospective multicentre observational study was designed to include patients with anal fistula treated by one- or two-stage fistulotomy. Data were collected using a self-administered questionnaire before surgery, during healing and at 1 year after surgery. RESULTS: Group A (133 patients) with a low anal fistula underwent a one-stage fistulotomy. The median Wexner scores before and after surgery were 1.0 (0-11) and 2.0 (0-18) (P = 0.032) and the median Vaizey scores were 2.0 (0-14) and 3.0 (0-21) (P = 0.055). The Wexner scores and percentage of patients before and after fistulotomy were as follows: 0-5: 88%, 86%; 6-10: 10.7%, 10.7%; 11-15: 1.0%, 2.6%; and 16-20: 0%, 2%. Eighty-seven per cent of the patients were satisfied. Group B (62 patients) underwent two-stage fistulotomy for a high transsphincteric fistula. The Wexner scores and percentage of patients before the first stage and 1 year after the second stage were as follows: 0-5: 86%, 66%; 6-10: 4.5%, 20%; 11-15: 9%, 11%; and 16-20: 0%, 2%. The median Wexner scores before the first stage and after the second stage were 1 (0-14) vs. 4 (0-19) (P < 0.001), and the median Vaizey scores were 1.5 (0-11) vs. 4 (0-20) (P < 0.001). Eighty-eight per cent of the patients were satisfied. CONCLUSION: Low transsphincteric anal fistula can be treated by fistulotomy without clinically significant continence disturbance. Treating high transsphincteric anal fistulae with two-stage fistulotomy is followed by mild continence disturbance. Satisfaction rates were high.

Sedentary Behaviour and Fall-related Injuries in Aging Adults: Results from the Canadian Longitudinal Study on Aging (CLSA).

Background: Falls, and more specifically, fall-related injuries, are costly to the healthcare system and can harm one's autonomy. Objectives: To study the impact of sedentary behaviour associated with fall-related injuries and how a change in sedentary behaviour may impact the risk of a fall-related injury. Design: From baseline to the first follow-up, cross-sectional and longitudinal data analysis from the Canadian Longitudinal Study of Aging (CLSA) cohort. Participants: CLSA data from 43,558 Canadians aged 45-85 were included in this study. Measurements: At baseline and follow-up, sedentary behaviour time was categorized as low (<1,080 minutes/week), moderate (1,080-1,440), or high (>1,440). Sedentary behaviour was estimated via the Physical Activity Scale for the Elderly (PASE). At follow-up, participants were dichotomized as either increased or decreased/no change in sedentary behaviour according to their categorical change between time points. Results: Sedentary behaviour was associated with fall-related injuries independently of age, sex, number of chronic conditions, and total physical activity levels OR (95%CI) 1.10 (1.05-1.15). In contrast, a change in sedentary behaviour was not associated with the risk of fall-related injury 1.00 (0.92-1.01). Conclusion: A higher level of sedentary behaviour is associated with injurious falls for people between 40 and 80 years old. However, a short-term change in sedentary behaviour does not influence the risk of injury-related falls. Despite the results, a more precise measure of sedentary behaviour is needed for epidemiology studies to capture changes over time better.

Sphincter-sparing anal-fissure surgery: a 1-year prospective, observational, multicentre study of fissurectomy with anoplasty.

AIM: Internal sphincterotomy is the standard surgical treatment for chronic anal fissure, but is frequently complicated by anal incontinence. Fissurectomy is proposed as an alternative technique to avoid sphincter injury. We describe 1-year outcomes of fissurectomy. METHOD: This was a prospective, multicentre, observational study. All patients with planned surgery for chronic anal fissure were included and had fissurectomy. Data were collected before surgery, at healing, and 1 year after fissurectomy. Patient self-assessed anal symptoms and quality of life (using the 36-item short-form health survey [SF-36] questionnaire). Presurgical and postsurgical variables were compared using the Wilcoxon signed-rank test for paired samples. RESULTS: Two-hundred and sixty-four patients were included (median age, 45 years; 52% women). Anoplasty was associated with fissurectomy in 83% of the 257 documented cases. The main complications were urinary retention (n = 3), local infection (n = 4) and faecal impaction (n = 1). Healing was achieved in all patients at a median of 7.5 weeks after surgery. No recurrence occurred. At 1 year, 210 (79%) questionnaires were returned. Median anal pain had dropped from 7.3/10 to 0.1/10 (P < 0.001), anal discomfort had decreased from 5.0/10 to 0.1/10 (P < 0.001) and the Knowles-Eckersley-Scott Symptom constipation score had decreased from 9/45 to 5/45 (P < 0.001). There was a nonsignificant increase in the Wexner anal incontinence score, from 1/20 to 2/20. De-novo clinically significant anal incontinence (Wexner score > 5) affected 7% of patients at 1 year, but presurgical incontinence had disappeared in 15% of patients. All SF-36 domains significantly improved. Anoplasty did not impact any result. CONCLUSION: Given its high rate of healing and low rate of de-novo anal incontinence, fissurectomy with anoplasty is a valuable sphincter-sparing surgical treatment for chronic anal fissure.

One-year outcome of haemorrhoidectomy: a prospective multicentre French study.

AIM: An evaluation was performed of the 1-year outcome of open haemorrhoidectomy (Milligan and Morgan alone or with posterior mucosal anoplasty [the Leopold Bellan procedure]). METHOD: A prospective, multicentre, observational study included all patients having a planned haemorrhoidectomy from January 2007 to June 2008. Data were collected before surgery, and at 3 months and 1 year after surgery. Patients assessed their anal symptoms and quality of life (SF-36). RESULTS: Six-hundred and thirty-three patients (median age = 48 years, 56.5% women) underwent haemorrhoidectomy either by the Milligan and Morgan procedure alone (n = 231, 36.5%) or together with the Leopold Bellan procedure (posterior mucosal anoplasty) for resection of a fourth haemorrhoid (n = 345, 54.5%), anal fissure (n = 56, 8.9%) or low anal fistula (n = 1, 0.16%). The median healing time was 6 weeks. Early complications included urinary retention (n = 3), bleeding (n = 11), local infection (n = 7) and faecal impaction (n = 9). At 1 year, the main complications included skin tags (n = 2) and anal stenosis (n = 23). There were three recurrences requiring a second haemorrhoidectomy. On a visual analogue scale, anal pain at 1 year had fallen from a median of 5.5/10 before treatment to 0.1/10 (p < 0.001), anal discomfort from 5.5/10 to 0.1/10 (P < 0.001) and the Knowles-Eckersley-Scott Symptom (KESS) constipation score from 9/45 to 6/45 (P < 0.001). The median Wexner score for anal incontinence was unchanged (2/20). De-novo anal incontinence (a Wexner score of >5) affected 8.5% of patients at 1 year, but preoperative incontinence disappeared in 16.7% of patients with this symptom. All physical and mental domains of quality of life significantly improved, and 88% of patients were satisfied or very satisfied. CONCLUSION: Complications of open haemorrhoidectomy were infrequent. Anal continence was not altered. Comfort and well-being were significantly improved at 1 year after surgery. Patient satisfaction was high despite residual anal symptoms.

Enhanced detection of infectious salmon anaemia virus using a low-speed centrifugation technique in three fish cell lines.

Infectious salmon anaemia (ISA), caused by ISA virus (ISAV), is a serious disease of farmed Atlantic salmon, Salmo salar L. Recently, molecular- and immunofluorescent-based techniques have become powerful diagnostic tools for ISAV detection, but culture-based techniques remain the gold standard. A disadvantage of ISAV culture is that the incubation time required before cytopathic effect (CPE) is observed in cell monolayers. To decrease time until CPE is observed, a low-speed centrifugation technique was applied to existing standard operating procedures for ISAV culture in three fish cell lines. Time until CPE observation was compared in CHSE, SHK and ASK cells, treated or not treated with low-speed centrifugation after inoculation with ISAV. Low-speed centrifugation treatment significantly enhanced observable cell infection. Compared to control cells, the length of time until ISAV CPE observation decreased in centrifuged ASK and CHSE cells. Low-speed centrifugation was also incorporated into a modified clinical shell vial assay. At 48 h post-inoculation with approximately 20 viral particles, ISAV was detected by an immunofluorescence antibody test in treated ASK and SHK1 cells but not in control cells. Finally, this enhanced viral adsorption assay performed in ASK cells demonstrated higher sensitivity than a real-time RT-PCR assay performed on RNA isolated from ISAV-spiked salmon kidney homogenates.

Validity of common physical function tests performed online for older adults.

BACKGROUND: Objectively measured physical function tests are important predictors of institutionalization, disability, and premature mortality. Although physical function was usually assessed in person prior to the COVID-19 pandemic, there is a need to investigate whether physical function tests performed online are valid. OBJECTIVE: The purpose of this study was to determine the validity of common physical function tests conducted online compared to in-person testing in older adults. METHODS: Physical functions included gait speed, one leg stance balance, 30-second chair stands, and the 2-minute steps were tested online and in-person using a random order for community dwellers aged 65 years and above. Using an alpha two way mixed model, average intraclass correlation coefficients (ICC) were calculated between the two settings and one sample T-test performed on the difference between the results of each test between the two settings. Finally, Bland-Altman plots were created, and proportional biases tested via linear regressions. RESULTS: Besides the one-leg stance balance with eyes closed, for which the ICC was 0.47 (0.23-0.74) the average ICC's were excellent ranging from 0.87 to 0.94. No proportional biases were observed based on Bland-Altman graphs. CONCLUSION: For older adults living in the community, common physical function tests can be performed online.

Relationships between internalized stigma and depression and suicide risk among queer youth in the United States: a systematic review and meta-analysis.

Background: Queer youth experience high rates of depression and suicidality. These disparities stem from stigma-based stressors, including internalized stigma (i.e., negative social views that minoritized individuals internalize about their own identity). Given the importance of this factor in understanding mental health disparities among queer youth, we completed a systematic review and meta-analysis examining the relationships between internalized stigma and outcomes of depression and suicide risk (i.e., suicidal ideation, non-suicidal self-injury, and suicidal behavior). Methods: We followed the PRISMA standards. Six bibliographic databases were searched for studies in the United States from September 2008 to March 2022. Dual independent screening of search results was performed based on a priori inclusion criteria. Results: A total of 22 studies were included for data extraction and review. Most studies examined general internalized homophobia, with few examining internalized biphobia or transphobia. Many studies examined depression as an outcome, few studies examined suicidal ideation or behavior, and no studies examined non-suicidal self-injury. Meta-analyses model results show the association between general internalized queer stigma and depressive symptoms ranged r = 0.19, 95% CI [0.14, 0.25] to r = 0.24, 95% CI [0.19, 0.29], the latter reflecting more uniform measures of depression. The association between internalized transphobia and depressive outcomes was small and positive (r = 0.21, 95% CI [-0.24, 0.67]). General internalized queer stigma and suicidal ideation had a very weak positive association (r = 0.07, 95% CI [-0.27, 0.41]) and an even smaller, weaker positive association with suicide attempt (r = 0.02, 95% CI [0.01, 0.03]). Conclusion: Implications for clinical practice, policy, and future research are discussed.

Do we have to stop anticoagulant and platelet-inhibitor treatments during proctological surgery?

AIM: This prospective observation study evaluated the incidence of secondary bleeding after proctological surgery without interruption of oral anticoagulant or platelet-inhibitor treatments. METHOD: The number of episodes of postoperative bleeding was identified prospectively from the day of surgery to the last follow-up visit in consecutive patients operated on during 2010 in two units dedicated to proctology. RESULTS: A total of 2513 procedures were performed in 2314 patients (1379 men), 46 ± 16 years of age. Secondary bleeding occurred after 115 (4.6%) procedures, no later than day 24 after surgery, requiring rehospitalization in 86% of cases and further surgery and/or transfusion in 36%. The highest frequency was noted after surgery for haemorrhoids (haemorrhoidopexy, 7.9%; haemorrhoidectomy, 6.2%) (P = NS and transanal excision of rectal tumours (6.5%). On multivariate analysis, the frequency was significantly increased by clopidogrel (15%) [relative risk (RR) = 10). In patients on oral anticoagulants, bleeding occurred in 23% (RR = 5.8) if the anticoagulants were not interrupted and in 57% (RR = 42) if the anticoagulants were discontinued and replaced with heparin. CONCLUSION: During proctological surgery the overall risk of postoperative bleeding is low, but it can occur up to 3 weeks after surgery and is often severe. Maintenance treatment with oral anticoagulants is the most important risk factor, aggravated by a change to heparin. Clopidogrel also significantly increases the bleeding risk.
