RESUMEN
Rosacea is a common chronic skin disease distributed primarily around the central face. Ocular manifestations of rosacea are poorly studied, and estimates of prevalence vary widely, ranging from 6% to 72% in the rosacea population. Treatment options for ocular rosacea include lid hygiene, topical and oral antibiotics, cyclosporine ophthalmic emulsion, oral vitamin A derivatives, and intense pulsed light; however, a direct comparison of treatment methods for ocular rosacea is lacking. This review aims to compare treatment efficacy and adverse events for different treatment modalities in ocular rosacea. We performed a systematic review by searching Cochrane, MEDLINE and Embase. Title, abstract, full text screening, and data extraction were done in duplicate. Sixty-six articles met the inclusion criteria, representing a total of 1,275 patients. The most effective treatment modalities were topical antimicrobials and oral antibiotics, which achieved complete or partial response in 91% (n = 82/90) and 89% (n = 525/580) of patients respectively, followed by intense pulsed light (89%, n = 97/109 partial response), cyclosporine ophthalmic emulsion (87% n = 40/46), and lid hygiene (65%, n = 67/105). Combination treatments achieved a complete or partial response in 90% (n = 69/77). Results suggest that topical antimicrobials, oral antibiotics, intense pulsed light. and cyclosporine were the most efficacious single modality treatments.

INTRODUCTION: Hand-foot-mouth disease (HFMD) is a common childhood infectious disease. Atypical skin findings of HFMD, often associated with coxsackievirus A6 (CVA6), were first reported in 2008, with increasing reports worldwide since. Atypical lesions of HFMD often involve sites beyond the palms and soles and tend to have unusual, polymorphic morphology. METHODS: A systematic review was conducted on clinical features and outcomes of pediatric HFMD with atypical cutaneous manifestations. RESULTS: Eighty-five studies were included, representing 1359 cases with mean age 2.4 years and a male predominance of 61%. The most reported morphologies were vesicles (53%), papules (49%), and bullae (36%). Other morphologies included eczema herpeticum-like (19%), purpuric/petechial (7%), and Gianotti Crosti-like (4%). Common atypical sites included the arms and/or legs (47%), face (45%), and trunk (27%). CVA6 was identified in 63% of cases. Symptoms resolved in a mean of 10 days. Overall, 16% of cases received treatment, most commonly with acyclovir, intravenous antibiotics, or topical steroids. The most common complications were nail changes (21%) and desquamation (4%) which occurred a mean of 3 and 2 weeks after symptoms, respectively. CONCLUSION: Due to unusual morphologies resembling other conditions, HFMD with atypical cutaneous findings may be misdiagnosed, leading to inappropriate and unnecessary investigations, hospitalization, and treatment. Greater awareness of atypical presentations of HFMD is warranted to improve patient care and counseling on infection control precautions.

Chilblain-like lesions (CLL) coinciding with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection have been described in the literature. Available reviews of the literature suggest that CLL are associated with younger age, an equal sex ratio, negative testing for SARS-CoV-2, and mild to no extracutaneous manifestations (ECM) associated with COVID-19 infection. This systematic review aims to provide a summary of reports of CLL associated with the early SARS-CoV-2 pandemic in children to clarify the prevalence, clinical characteristics, and resolution outcomes of these skin findings. Sixty-nine studies, published between May 2020 and January 2022, met inclusion criteria and were summarized in this review, representing 1,119 cases of CLL. Available data showed a slight male predominance (591/1002, 59%). Mean age was 13 years, ranging from 0 to 18 years. Most cases had no ECM (682/978, 70%). Overall, 70/507 (14%) of patients tested positive for COVID-19 using PCR and/or serology. In the majority the clinical course was benign with 355/415 (86%) of cases resolving, and 97/269 (36%) resolving without any treatment. This comprehensive summary of pediatric CLL suggests these lesions are rarely associated with COVID-19 symptoms or test positivity.

BACKGROUND: Aerobic exercise promotes cognitive function in older adults; however, variability exists in the degree of benefit. The brain-derived neurotropic factor (BDNF) Val66Met polymorphism and biological sex are biological factors that have been proposed as important modifiers of exercise efficacy. Therefore, we assessed whether the effect of aerobic exercise on executive functions was dependent on the BDNFval66met genotype and biological sex. METHODS: We used data from a single-blind randomized controlled trial in older adults with subcortical ischemic vascular cognitive impairment (NCT01027858). Fifty-eight older adults were randomly assigned to either the 6 months, three times per week progressive aerobic training (AT) group or the usual care plus education control (CON) group. The secondary aim of the parent study included executive functions which were assessed with the Trail Making Test (B-A) and the Digit Symbol Substitution Test at baseline and trial completion at 6 months. RESULTS: Analysis of covariance, controlling for baseline global cognition and baseline executive functions performance (Trail Making Test or Digit Symbol Substitution Test), tested the three-way interaction between experimental group (AT, CON), BDNFval66met genotype (Val/Val carrier, Met carrier), and biological sex (female, male). Significant three-way interactions were found for the Trail Making Test (F(1,48) = 4.412, p < 0.04) and Digit Symbol Substitution Test (F(1,47) = 10.833, p < 0.002). Posthoc analyses showed female Val/Val carriers benefited the most from 6 months of AT compared with CON for Trail Making Test and Digit Symbol Substitution Test performance. Compared with CON, AT did not improve Trail Making Test performance in male Val/Val carriers or Digit Symbol Substitution Test performance in female Met carriers. CONCLUSIONS: These results suggest that future randomized controlled trials should take into consideration BDNF genotype and biological sex to better understand the beneficial effects of AT on cognitive function in vascular cognitive impairment to maximize the beneficial effects of exercise and help establish exercise as medicine for cognitive health.

INTRODUCTION: We aimed to evaluate the real-world effectiveness and safety of tofacitinib for the treatment of ulcerative colitis (UC). METHODS: REMIT-UC is a Canadian multicenter cohort study. Standardized data collection was performed on 334 consecutive adult outpatients with UC treated with tofacitinib. The primary outcomes were achievement of clinical and endoscopic remission. Safety outcomes were reported using incidence rates (events/100 patient-years of exposure). A multivariable Cox proportional hazards model was used to evaluate predictors of loss of response after tofacitinib dose de-escalation to 5 mg twice daily (BID). RESULTS: Clinical remission was achieved by 35.3% (106/300), 36.0% (104/289), and 35.2% (93/264) of patients at weeks 12, 24, and 52, respectively. Endoscopic remission was achieved by 18.5% (15/81), 23.0% (28/122), and 25.7% (35/136) of patients at weeks 12, 24, and 52, respectively. Incidence of serious infections, herpes zoster, and venous thromboembolism were 2.1 [0.9-4.2], 0.5 [0.1-1.9], and 1.1 [0.3-2.7], respectively. Among responders, 44.5% (109/245) lost response during follow-up, which was recaptured in 54.9% (39/71) of patients who re-escalated to 10 mg BID. Patients with a baseline Mayo endoscopic score of 3 (adjusted hazard ratio 3.60 [95% confidence interval: 1.70-7.62]) and prior biologic failure (adjusted hazard ratio 3.89 [95% confidence interval: 1.28-11.86]) were at a higher risk for losing response after dose reduction. DISCUSSION: One-third of patients with UC treated with tofacitinib achieved clinical remission with few serious adverse events. However, half of patients lost response with de-escalation, which was only partially recaptured with increasing the maintenance dose. Those with negative prognostic factors should be counselled about the risks and benefits of continuing high doses of tofacitinib.

Chilblain-like lesions (CLL) coinciding with SARS-CoV-2 infection have been described. Previous systematic reviews suggest CLL are associated with younger age, an equal sex ratio, negative testing for SARS-CoV-2, and mild to no extracutaneous symptoms. A systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines on CLL coinciding with SARS-CoV-2 to clarify the demographic characteristics, clinical features, and resolution outcomes of these skin findings. One hundred twenty-eight studies, published between March 2020 and January 2022, met inclusion criteria and were summarized in this review, representing 4,982 cases of CLL. Available data showed a slight female predominance (55%, n = 2,471 of 4,472). The mean age was 25 years, ranging from 0 to 95 years. Most cases were not associated with extracutaneous signs and symptoms (63%, n = 1,649 of 2,636). Overall, 19% (n = 347 of 1,838) of patients tested positive for SARS-CoV-2 using polymerase chain reaction, serology, or tissue biopsy. Clinical course was generally benign with 80% (n = 979 of 1,224) of cases resolving and 47% (n = 204 of 432) resolving without receiving treatment. This review provides a comprehensive summary of CLL associated with SARS-CoV-2. CLL occurred at a mean age of 25 years with a slight female predominance. The majority had negative COVID-19 testing, no extracutaneous signs and symptoms, and resolution without recurrence.

PURPOSE: Among older adults, health-related quality of life (HRQoL) and falls are associated. Generic patient-reported outcomes measures (PROMs) assess individual's HRQoL. The role for PROMs, a potential tool for predicting subsequent falls, remains under-explored. Our primary aim was to determine whether a baseline PROMs assessment of HRQoL may be a useful tool for predicting future falls. METHODS: A secondary analysis of a 12-month randomized clinical trial (RCT) of a home-based exercise program among 344 adults (67% female), aged ≥ 70 years, with ≥ 1 falls in the prior year who were randomized (1:1) to either a home-based exercise program (n = 172) or usual care (n = 172). A negative binomial regression model with total falls count as the dependent variable evaluated the main effect of the independent variable-baseline HRQoL (measured by the Short-Form-6D)-controlling for total exposure time and experiment group (i.e., exercise or usual care) for the total sample. For the usual care group alone, the model controlled for total exposure time. RESULTS: For the total sample, the rate of subsequent total falls was significantly predicted by baseline HRQoL (IRR = 0.044; 95% CI [0.005-0.037]; p = .004). For the usual care group, findings were confirmed with wider confidence intervals and the rate of prospective total falls was significantly predicted by baseline HRQoL (IRR = 0.025; 95% CI [0.001-0.909]; p = .044). CONCLUSION: These findings suggest the ShortForm-6D should be considered as part of falls prevention screening strategies within a Falls Prevention Clinic setting.

OBJECTIVES: To assess the effect of exercise training on the cognitive function of older adults living with different types of dementia, as well as potential moderators of exercise efficacy. DESIGN: Systematic review and meta-analysis. DATA SOURCES: Cochrane Central, PsycINFO, Embase, Medline and CINAHL. ELIGIBILITY CRITERIA: Peer-reviewed, randomised controlled trials, in English (1990-present), which examined the effects of exercise training on the cognitive function of older adults living with dementia. STUDY APPRAISAL AND SYNTHESIS: Risk of bias and study quality were assessed (Cochrane Risk of Bias Tool 2.0 and Physiotherapy Evidence Database Scale). We performed random-effects models using robust variance estimation and tested moderators using the approximate Hotelling-Zhang test. RESULTS: Twenty-eight studies (n=2158) were included in the qualitative review and 25 in the meta-analysis. For all-cause dementia, a small effect of exercise training on cognitive function was observed (g=0.19; 95% CI 0.05 to 0.33; p=0.009). Type of dementia and exercise training characteristics did not moderate the effects of exercise training on cognitive function (p>0.05). Adherence to the intervention moderated the cognitive outcome effect size such that greater mean adherence was associated with greater cognitive outcome effect sizes (b=0.02; SE=0.01; p=0.005). CONCLUSION: Exercise training showed small benefits for the cognitive function of older adults living with all-cause dementia. More research and standardised reporting of exercise training characteristics can strengthen the evidence for what works best for which types of dementia.

RESUMEN
BACKGROUND: Among individuals with nonvalvular atrial fibrillation (AF), the prevalence of obstructive sleep apnea (OSA) can be as high as 85%. Continuous positive airway pressure treatment for moderate or severe OSA might improve AF outcomes and quality of life, so early identification of OSA might be of value. However, screening questionnaires for OSA are suboptimal because they are weighted toward tiredness and loud snoring, which might be absent in AF patients. NoSAS (Neck, Obesity, Snoring, Age, Sex) is a new OSA questionnaire that excludes these parameters. Acoustic pharyngometry (AP) is a potential novel screening technique that measures pharyngeal cross-sectional area, which is reduced in patients with OSA. METHODS: We prospectively compared the accuracy of the NoSAS, the STOP-BANG questionnaire (Snoring, Tiredness, Observed apnea, blood Pressure, Body mass index, Age, Neck circumference and Gender), and AP with home sleep apnea testing (HSAT) in consecutive patients with nonvalvular AF. RESULTS: Of 188 participants, 86% had OSA and 49% had moderate or severe OSA. Mean Epworth Sleepiness Scale scores were low; 5.9 (SD, 3.9), indicating that most participants were not sleepy. Receiver operating characteristic curves for comparisons of screening tests with HSAT showed suboptimal accuracy. For moderate plus severe and severe only groups respectively, the area under the curve was 0.50 (95% confidence interval [CI], 0.42-0.58) and 0.42 (95% CI, 0.34-0.52) for AP, 0.65 (95% CI, 0.58-0.73) and 0.63 (95% CI, 0.52-0.74) for the STOP-BANG questionnaire, and 0.68 (95% CI, 0.60-0.75) and 0.69 (95% CI, 0.59-0.80) for the NoSAS. CONCLUSIONS: AP and NoSAS are not sufficiently accurate for screening AF patients for OSA. Because of the high rates of OSA in this cohort, the potential benefits of OSA treatment, and the suboptimal accuracy of current screening questionnaires, cardiologists should consider HSAT for AF patients.
CONTEXTE: Chez les sujets présentant une fibrillation auriculaire (FA) non valvulaire, la prévalence de l'apnée obstructive du sommeil (AOS) peut atteindre 85 %. En cas d'AOS modérée ou sévère, un traitement par ventilation spontanée en pression positive continue peut améliorer les résultats liés à la FA et la qualité de vie du patient; un diagnostic précoce d'AOS pourrait donc être utile. Les questionnaires de dépistage de l'AOS ne sont toutefois pas optimaux parce qu'ils accordent une grande importance à la fatigue et aux ronflements sonores, des symptômes qui ne se manifestent pas nécessairement en cas de FA. Le questionnaire NoSAS (de l'anglais Neck, Obesity, Snoring, Age, Sex) est un nouvel outil d'évaluation de l'AOS qui ne tient pas compte de ces paramètres. La pharyngométrie acoustique (PA) pourrait aussi constituer une nouvelle technique de dépistage; elle mesure l'aire de section transversale du pharynx, qui est réduite chez les patients souffrant d'AOS. MÉTHODOLOGIE: Nous avons comparé de façon prospective la précision du score au questionnaire NoSAS, du score au questionnaire STOP-BANG (de l'anglais Snoring, Tiredness, Observed apnea, blood Pressure, Body mass index, Age, Neck circumference and Gender) et des résultats de la PA à celle du test d'apnée du sommeil à domicile (TASD) chez des patients consécutifs présentant une FA non valvulaire. RÉSULTATS: Sur les 188 participants, 86 % présentaient une AOS et 49 % souffraient d'AOS modérée ou sévère. Le score moyen sur l'échelle de somnolence d'Epworth était faible et se situait à 5,9 (écart-type : 3,9), ce qui indique que la plupart des participants ne ressentaient pas de somnolence. La comparaison entre les questionnaires de dépistage et le TASD effectuée au moyen des courbes caractéristiques de la performance des tests a révélé une précision sous-optimale. Dans les groupes souffrant d'AOS modérée ou sévère et d'AOS sévère seulement, les aires sous la courbe étaient respectivement de 0,50 (intervalle de confiance [IC] à 95 % : de 0,42 à 0,58) et de 0,42 (IC à 95 % : de 0,34 à 0,52) pour la PA, de 0,65 (IC à 95 % : de 0,58 à 0,73) et de 0,63 (IC à 95 % : de 0,52 à 0,74) pour le questionnaire STOP-BANG, et de 0,68 (IC à 95 % : de 0,60 à 0,75) et de 0,69 (IC à 95 % : de 0,59 à 0,80) pour le questionnaire NoSAS. CONCLUSIONS: La PA et le questionnaire NoSAS ne sont pas suffisamment précis pour dépister l'AOS chez les patients présentant une FA. Compte tenu de la forte prévalence de l'AOS dans cette cohorte, des bienfaits potentiels d'un traitement de l'AOS et de la précision sous-optimale des questionnaires de dépistage actuels, il conviendrait d'envisager un TASD chez les patients présentant une FA.
