Abstract
PURPOSE Kinesio taping (KT) is an approach that has been used in the rehabilitation of patients with chronic stroke. The aim of this review is to evaluate the effectiveness of KT alone or combined with other interventions for patients with chronic stroke. MATERIALS AND METHODS The search was performed on CENTRAL, EMBASE, PEDro, and five other databases and two trial registries up to July 2022. We included randomized controlled trials that evaluated the effectiveness of KT compared to control interventions. The primary outcomes were upper limb function and gait. We assessed the risk of bias in the included studies using the PEDro scale. The certainty of the evidence was assessed using the GRADE approach. RESULTS We included 14 RCTs undertaken in six different countries. PEDro score ranged from 4 to 9 points. There is very-low certainty evidence that KT has no effect on gait, balance, and postural control. We found very-low certainty evidence of a slightly benefit when used in addition to other therapies for gait, balance and postural control, and pain intensity. CONCLUSIONS Our study findings show KT does not have enough robust evidence for improving upper limb function, gait, balance and postural control, and pain intensity in chronic stroke patients.

Introduction
The proportion of non-ST-segment elevation myocardial infarction (NSTEMI) is increasing among the acute coronary syndromes (ACS). Reinfarction (RI) is a potential complication in high-risk patients with NSTEMI and it will cause an impact on these patients’ prognosis.
Purpose
Identify high-risk patients with RI and their prognosis in the setting of NSTEMI.
Methods
Based on a multicenter retrospective study, data collected from admissions between January 2013 and January 2020. Patients without data on previous cardiovascular history or uncompleted clinical data were excluded. Patients were divided in 2 groups (G): G1 – patients without RI; G2 - patients with RI during hospitalization. Logistic regression and survival analysis were performed.
Results
7180 patients were admitted with NSTEMI, RI occurred in 71 pts (0.99%). Regarding epidemiological and past history G2 was older (71±12 vs 66±12, p=0.001), had higher rates of previous stroke (15.9% vs 7.0%, p 0.003) and peripheric arterial disease (6.3% vs 6.1%, p=0.004). The groups were similar regarding arterial hypertension (p=0.74), diabetes type 2 (p=0.11) and dyslipidaemia (p=0.48).
G2 had higher levels of brain natriuretic peptide (45.5% vs 24.5%, p<0.001) and lower levels of haemoglobin (20.3% vs 7.9%, p<0.001). Patients taking prasugrel (2% vs 0.3%, p=0.002) or ticagrelor (6.1% vs 2.2%, p<0.001) previously to the admission were more susceptible to have RI. Patients with severe left ventricular systolic dysfunction (3.4% vs 2.6%, p<0.001), need of invasive (2.8% vs 0.8%, p<0.001) or non-invasive (4.2% vs 1.3%, p<0.001) ventilation and percutaneous coronary intervention (PCI) (80.3% vs 64.7%, p0.006) had higher rates of RI.
Logist regression confirmed that PCI (p=0.03, OR 2.22, CI 1.08-4.53), previous stroke (p=0.02, OR 0.58, CI 0.37-0.92) and pts previously taking prasugrel (p=0.02, OR 1.85, CI 1.11-3.10) were predictors of RI in the setting of NSTEMI.
Conclusion
RI in the setting of NSTEMI was associated with PCI, previous stroke and pts previously taking prasugrel. One year prognosis was poorer for patients who suffered RI.

Introduction
Cardio-cerebral vascular diseases are a leading cause of deaths worldwide.
Stroke is a potential complication in high-risk patients who had non-ST-segment elevation myocardial infarction (NSTEMI).
Purpose
Identify high-risk patients with stroke and their prognosis in the setting of NSTEMI.
Methods
Based on a multicenter retrospective study, data collected from admissions between January 2013 and January 2020. Patients without data on previous cardiovascular history or uncompleted clinical data were excluded. Patients were divided in 2 groups (G): G1 – patients who suffered stroke; G2 - patients without stroke. Logistic regression and survival analysis were performed.
Results
7180 patients were admitted with NSTEMI, stroke occurred in 35 patients (0.49%). Regarding epidemiological and past history G1 was older (72±9 vs 66±12, p= 0.004), had more females (54.3% vs 45.75, p<0.001), had higher rates of type 2 diabetes mellitus (51.3% vs 35.2%, p=0.05), previous strokes / transient ischemic attack (24.2% vs 7.0%, p=0.007) and dementia (3.3% vs 0.8%, p<0.001). Arterial hypertension (77.1 vs 72.8%, p=0.56), dyslipidaemia (61.8% vs 63.0%, p=0.88) and smoking (17.6% vs 26.0%, p=0.27) were similar between groups. Patients who presented with chest pain (72.7% vs 92.0%, p<0.001) and patients who were not revascularized were more likely to suffer a stroke (43.3% vs 17.5%, p<0.001).
Logist regression only confirmed that females were more likely to have a stroke (p<0.001, OR 4.13, CI 1.87-9.15) and patients who presented with chest pain (p=0.001, OR 0.23, CI 0.10-0.54). One year event-free survival was higher in patients who did not have stroke (95.3% vs 80.0%, p=0.005, OR 4.50, CI 1.43-14.15)
Conclusion
Since sex gender and form of presentation of NSTEMI are not modifiable factors we cannot prevent strokes from happening in the context of NSTEMI.

Abstract
ABSTRACT A case of a donkey attacked by Africanized honeybee is reported here with clinical signs of agitation, dehydration, congestion of the ocular mucous membranes, tongue edema, tachycardia and inspiratory dyspnea, and progression to death. At necropsy, diffuse, severe subcutaneous edema at face and cervical regions and severe diffuse pulmonary hyperemia with abundant edema without parenchymal collapse were observed. Microscopically, marked, diffuse deep dermis and panniculus carnosus edema and marked diffuse alveolar edema, with moderate population of eosinophils predominantly around larger caliber vessels were noted. The final diagnosis of anaphylactic shock was supported by history, clinical signs, and anatomic pathology findings. This is the first report of a honeybee attack with pulmonary eosinophilic infiltration in a mammal.

Abstract
Abstract
Background
Atrial fibrillation (AF) is frequent in patients admitted with acute coronary syndromes (ACS). The development of this arrhythmia occurs in 2–21% of patients with non ST-elevation ACS and 21% of ST-elevation ACS. According with the most recent European guidelines, a short period up to 1 week of triple antithrombotic therapy (TAT) is recommended, followed by dual antithrombotic therapy (DAT) using a NOAC and a single antiplatelet agent, preferably clopidogrel.
Objective
To compare the antithrombotic strategy (DAT vs TAT) used and its prognostic value in patients with AF and ACS.
Methods
Retrospective analysis of patients' data admitted with ACS in a multicentric registry between 10/2010–09/2019. TAT was defined as the prescription of dual antiplatelet therapy and one anticoagulant and DAT as one antiplatelet and one anticoagulant. Survival and rehospitalization were evaluated through Kaplan-Meier curve.
Results
1067 patients were included, mean age 67±14 years, 72.3% male. Patients who developed de novo AF during hospitalization due to ACS were older (75±12 vs 66±14 years, p<0.001) and with higher prevalence of cardiovascular risk factors and cardiovascular disease. AF was more often in patients with ST elevation ACS (53.4%). During hospitalization, AF patients were more often medicated with aspirin, glycoprotein inhibitor, heparin, fondaparinux and vitamin K antagonists. No difference was found regarding P2Y12 inhibitors. AF patients presented more often obstructive coronary disease (normal coronaries 5.4 vs 8.5%, p<0.001) so they were more often submitted to PCI (79.5 vs 70.9%, p<0.001). AF patients presented with higher rates of adverse in-hospital events as re-infarction, heart failure, shock, ventricular arrhythmias, cardiac arrest, stroke, major bleeding and death (p<0.001). At discharge, AF patients were less prescribed with aspirin or ticagrelor, but the rate of clopidogrel prescription was higher, such as vitamin K antagonists or any of the new anticoagulants. In the AF group, 21.5% patients were discharged with TAT and 30.3% with DAT. Concerning patients discharged with TAT, 1-year follow-up revealed no significant differences in mortality (p=0.578), re-admission for cardiovascular causes (p=0.301) and total re-admission rates (p=0.291). Patients discharged with DAT had similar mortality (p=0.623) and re-admission for cardiovascular causes rates (p=0.138), but significant differences were identified regarding total re-admissions (p=0.024).
Conclusions
In patients with ACS and de novo AF, a low percentage of patients was discharged with oral anticoagulation (51.8%). In those whose anticoagulation was initiated, DAT was the preferred strategy. 1-year outcomes were not different between the antithrombotic strategy, except for all cause re-admission.

Portuguese Registry of Acute Coronary Syndromes
Background
Sustained ventricular tachycardia (VT) is a frequent rhythm disturbance during an ischemic event like acute coronary syndrome (ACS). VT was frequently associated with worse prognosis, then is expected, that its presence is related to a higher incidence of major adverse cardiac events (MACE).
Objective
Evaluate if sustained VT was a predictor of MACE in ACS hospitalized patients.
Methods
Multicenter retrospective study, based on the Portuguese Registry of ACS between 1/10/2010-4/09/2019. Patients were divided into two groups: A – patients without VT, and B – patients that presented VT on the hospitalization. VT was defined as a register or more of the VT with at least 30 seconds. Were excluded patients without a previous cardiovascular history or clinical data. MACE was defined as re-infarction, congestive heart failure, cardiogenic shock, a mechanical complication of myocardial infarction, completed atrioventricular block, sustained ventricular tachycardia, cardiac arrest, stroke and hospitalization death. Univariate logistic regression was performed to assess if VT in ACS patients was a predictor of MACE.
Results
A total of 29851 patients was analyze and 25725 had information regarding VT. From the group of patients that presented VT, 177 (1.1%) had re-infarction, 2415 (14.1%) had congestive heart failure, 816 (5.0%) had atrial fibrillation, 108 (0.7%) had a mechanical complication of myocardial infarction, 442 (2.7%) had completed atrioventricular block, 458 (2.8%) had cardiac arrest, 101 (0.6%) had stroke and 535 (3.3%) died. VT did not predict re-infarction (p = 0.071), mechanical complication of myocardial infarction (p = 0.979) and stroke (p = 0.500) in ACS hospitalized patients. Logistic regression revealed that VT in ACS patients was a predictor of congestive heart failure (odds ratio (OR) 2.304, p < 0.001, confidence interval (CI) 1.742-3.047), atrial fibrillation (OR 2.078, p < 0.001, CI 1.453-2.973), completed atrioventricular block (OR 1.831, p = 0.012, CI 1.145-2.928), cardiac arrest (OR 15.434, p < 0.001, CI 11.429-20.843) and hospitalization death (OR 6.472, p < 0.001, CI 4.484-9.342).
Conclusions
VT in ACS patients predict MACE, namely congestive heart failure, atrial fibrillation, completed atrioventricular block, cardiac rest and hospitalization death.

Background
The presence of atrioventricular block (AVB) in ST-elevation myocardial infarction (STEMI) is more frequently registered when is identified in the inferior leads. However, AVB maybe occurs in anterior STEMI, yet the AVB and STEMI localization maybe had different implications.
Objective
Evaluate the impact and prognosis of AVB according to the STEMI localization.
Methods
Multicenter retrospective study, based on the Portuguese Registry of Acute Coronary Syndrome between 1/10/2010-3/05/2020. Patients were divided into two groups: A – patients with anterior STEMI, and B – patients with inferior STEMI. Were excluded patients without a previous cardiovascular history or clinical data regarding AVB occurrence. Logistic regression was performed to assess AVB as a prognostic marker in STEMI patients.
Results
From 32157 patients, was identified 462 with AVB, 72 in group A (15.6%) and 390 in group B (84.4%). Both groups were similar regarding gender (p = 0.710), age (p = 0.068), body mass index (p = 0.535), admitly directly to cat lab (p = 0.635), initial symptons until first medical contact (p = 0.561), smoker status (p = 0.483), diabetes mellitus (p = 0.331), coronary artery disease (p = 0.053), previous stroke (p = 0.332), peripheral artery disease (p = 0.348), chronic kidney disease (p = 0.425), systolic blood pressure (p = 0.057), multivessel diasease (p = 0.235), new-onset of atrial fibrillation (p = 0.582), cardiac arrest (p = 0.062) and stroke complication (p = 0.685). Group B had higher left ventricular ejection fraction (LVEF) >50% (16.9 vs 60.7%, p < 0.001). On the other hand, group A had more arterial hypertension (79.7 vs 66.2%, p = 0.027), dislipidaemia (58.2 vs 54.4%, p = 0.038), heart rate at admission (81 ± 20 vs 59 ± 23, p < 0.001), Killip-Kimball class > I (45.7 vs 29.6%, p = 0.008), sinus rhythm at admission (84.5 vs 72.6%, p = 0.035), heart failure complication (65.3 vs 37.1%, p < 0.001), cardiogenic shock complication (42.3 vs 24.7%, p < 0.001), ACS mechanical complication (8.3 vs 3.1%, p = 0.047), sustained ventricular tachycardia during ACS hospitalization (19.4 vs 8.5%, p = 0.005) and hospitalization death (52.9 vs 44.7%, p < 0.001). Logistic regression revealed that AVB in inferior STEMI was a predictor of new-onset of atrial fibrillation (odds ratio (OR) 3.817, p = 0.038, confidence interval (CI) 1.123-12.975), with a R2 Nagelkerke 24.4. Also, revealed that AVB in anterior STEMI was a predictor of death (OR 0.111, p < 0.001, CI 0.034-0.366), with a R2 Nagelkerke 55.2.
Conclusions
AVB in inferior STEMI was a predictor of new-onset of atrial fibrillation and AVB in anterior STEMI was a predictor of death.

Background
Acute coronary syndromes (ACS) are frequent and are associated with high levels of comorbidities and complications. Ventricular tachycardia (VT) is one of the most danger and stressful situations in ACS.
Objective
Evaluate predictors of ventricular tachycardia in ACS.
Methods
Multicenter retrospective study, based on the Portuguese Registry of ACS between 1/10/2010-4/09/2019. Patients were divided in two groups: A – patients without VT, and B – patients that presented VT on the hospitalization. VT was defined as a register or more of the VT with at least 30 seconds. Logistic regression was performed to assess predictors of VT in ACS patients.
Results
25361 in group A (98.6%) and 364 in group B (1.4%). Both groups were similar regarding gender, cardiovascular risk factors, except for dyslipidemia (61.7 vs 51.9%, p < 0.001) and ST-segment elevation myocardial infarction (STEMI) location. Group B was elderly (67 ± 14 vs 70 ± 14, p < 0.001), was admitted directly to the cat lab (10.6 vs 20.4%, p < 0.001), had less time since the onset of symptoms until the admission (383 ± 157 vs 349 ± 121, p = 0.003), but presented higher previous history of heart failure (5.9 vs 10.6%, p < 0.001), peripheral vascular disease (5.5 vs 8.4%, p = 0.015), chronic obstructive pulmonary disease (COPD) (4.4 vs 7.9%, p = 0.001) and dementia (1.7 vs 3.2%, p = 0.038). At admission presented higher levels of STEMI (42 vs 67%, p < 0.001), dyspnea (29 vs 18.1%, p < 0.001), syncope (1.3 vs 6.6%, p < 0.001), cardiac arrest (0.4 vs 4.4%, p < 0.001), Killip-Kimball classification > I (14.8 vs 40.5%, p < 0.001) and atrial fibrillation at admission (AF) (7.1 vs 15.3%, p < 0.001). Ivabradine (3.7 vs 7.6%, p < 0.001), aldosterone receptor antagonists (10.2 vs 24%, p < 0.001), diuretic (28 vs 57.2%, p < 0.001), amiodarone (5.6 vs 53.5%, p < 0.001), digoxin (1.4 vs 4.7%, p < 0.001) were more prevalent used in the admission. Group B exhibited higher multivessel disease (MVD) (51.5 vs 61.5%, p < 0.001), culprit as common coronary trunk (CT) (1.7 vs 4.2%, p = 0.024), hybrid revascularization (0.8 vs 2%, p = 0.032) and left ventricular ejection fraction (LVEF)<50% (38.7 vs 71%, p < 0.001). On the other hand, the used of beta block (81.4 vs 62.3%, p < 0.001), angiotensin-converting-enzyme inhibitor (85.5 vs 74.4%, p < 0.001) and calcium channel blockers (10.1 vs 24%, p < 0.001) since had a protect effect. Regarding reinfarction (0.9 vs 2.5%, p = 0.007), de novo heart failure (15.1 vs 50.3%, p < 0.001), atrioventricular block (2.2 vs 17%, p < 0.001), stroke (1.4 vs 4.9%, p < 0.001) and death (3.4 vs 26.9%, p < 0.001), all were higher in Group B. Logistic regression revealed COPD (odds ratio (OR) 1.9, p = 0.010, confidence interval (CI) 1.17-3.10), STEMI (OR 2.73, p < 0.001, CI 2.00-3.73), AF (OR 2.30, p < 0.001, CI 1.52-3.49), MVD (OR 1.44, p = 0.012, CI 1.08-1.92), CT (OR 2.87, p = 0.003, CI 1.45-5.69) and LVEF < 50% (OR 3.44, p < 0.001, CI 2.52-4.71) as predictors of VT in ACS.

Background
Endocardial left ventricular pacing is a technique used in cardiac resynchronization therapy (CRT), when a coronary sinus implant is not possible, conventional CRT was an unsuccess and in CRT nonresponders. We performed a systemic review to evaluate its risks and benefits.
Objective
Review the evidence regarding the efficacy and safety of endocardial left ventricular pacing.
Methods
A systemic research on MEDLINE and PUBMED with the term "endocardial left ventricular pacing", "biventricular pacing" or "endocardial left pacing". 1038 results were identified, however, just publish papers (excluding abstract) with more than 16 patients was admitted in these analyses. Comparisons pre and post CRT regard New York Heart Association (NYHA) functional classification, left ventricular ejection fraction (LVEF) and QRS width was performed. Mean differences (MD) and confidence interval (CI) was used as a measurement of treatment.
Results
Eleven studies were selected, including a total of 560 patients. The studies were performed with different techniques, trans-atrial septal technique, trans-ventricular septal technique and transapical technique. Mean age 66.93 years old, 90.54% male, median ejection fraction of 28.86%, NYHA class of 3.03, QRS width 167,50 mseg. Ischemic etiologic in 43.88%, atrial fibrillation in 45.35% and left bundle branch block in 55.20%. Was reported several complications after the procedure, 8 pocket infection (7 studies), 17 transient ischemic attacks (10 papers), 17 ischemic stroke (all), 35 tromboembolic events (all) and 115 deaths, nevertheless, follow up in the different studies was diverse and heterogeneous. Significant improvement was registered in NYHA class (MD 0.64, CI 0.56-0.72, p < 0.00001, I2 = 89%) (reported in 7 studies), LVEF (MD 6.20, CI 5.09-7.32, p = 0.002, I2 = 69%) %) (reported in 8 studies) and QRS width (MD 31.35, CI 26.11-36.60, p < 0.00001, I2 = 89%) %) (reported in 5 studies), (all p < 0.00001).
Conclusions
Left ventricular endocardial pacing is a feasible alternative to conventional CRT, when the last one is not possible. With clinical, electrocardiogram and echocardiogram improvement in several series. First data regarding this procedure were associated with higher stroke incidence, something contrary to the last study’s results. Nevertheless, at the moment just small series present this technique with heterogenous results and different approaches, being important further investigation.

Background
The optimal right ventricular defibrillator lead placement is still a debatable matter. We attempt to performed a systemic review to evaluate whether septal and apical placement had significant differences in the follow-up with an indication for implantation of these devices.
Objective
Review the evidence regarding the efficacy and safety of right ventricular apical and septal defibrillator lead placement.
Methods
A systemic research on MEDLINE and PUBMED with the term "septal pacing", "apical pacing" "septal defibrillation" or "apical defibrillation". 309 results were identified, however, after a serious analysis, several articles were excluded. Comparisons between apical and septal placement were performed regarding R wave amplitude, pacing threshold at 0.5 ms, lead impedance, left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD) and lead complication that produced lead re-placement. Mean differences (MD) and confidence interval (CI) was used as a measurement of treatment.
Results
Six studies were selected, including a total of 2180 patients. The studies were performed with different techniques, analyses and goals. The studies presented heterogeneous and diverse results, with a varied follow-up period, that resulted in the exclusion of one of the studies. Mean age 64.51 years old, 76.86% male, a median ejection fraction of 27.84%, NYHA class of 2.65, ischemic etiologic in 51.10% and a follow-up period of 26.49 months. Septal defibrillator lead placement was established in 772 patients, while the apical defibrillator lead placement was performed in 1399 patients. No differences regarding the lead performance on apical and septal placement were detected regarding the R-wave (MD -0.36, CI -0.75 - +0.03, p = 0.68, I2 = 0%) (reported in 3 studies) and lead impedance (MD -23.83, CI -51.36 - +3.69, p = 0.003, I2 = 82%) (reported in 3 studies). Pacing threshold seems to be favor a septal defibrillator lead implantation (MD -0.05, CI -0.09 - -0.02, p = 0.12, I2 = 53%) (reported in 3 studies). Concerning echocardiography parameters during the follow up period, LVEF (MD -0.83, CI -3.05 - +1.38, p = 0.10, I2 = 57%) (reported in 3 studies) and LVEDD (MD -0.51, CI -2.13 - +1.10, p = 0.20, I2 = 38%) (reported in 3 studies) were not significant influenced for the defibrillator lead placement. Lead complications that provoke a lead replacement was not significant between the lead placement (MD 1.25, CI 0.53 – 2.94, p = 0.71, I2 = 0%) (reported in 3 studies).
Conclusions
Just pacing threshold proved to improve the septal defibrillator lead placement. Neither the other lead parameters or the echocardiography results during the follow-up were influenced by the lead placement. For a definitive conclusion is important to further investigation.

Background
Acute coronary syndrome (ACS) and atrial fibrillation (AF) are common diseases in developed countries and in some cases, the first episode of AF can occur during the ACS. A stressful event like an ACS can be a trigger for AF, being important to realize its impact and prognosis in the short and long term.
Objective
Evaluate the impact and prognosis of new-onset AF in ACS.
Methods
Multicenter retrospective study, based on the Portuguese Registry of ACS between 1/10/2010-4/09/2019. Patients were divided into two groups: A – patients without new-onset AF, and B – patients that presented new onset of AF. Were excluded patients without a previous cardiovascular history or clinical data during the admission and the follow-up period. Logistic regression was performed to assess if new-onset AF in ACS was a predictor of major adverse cardiac events and mortality. Kaplan-Meier test was performed to establish the survival rates and re-admission for one year of follow up.
Results
9687 patients suffered ACS and had follow-up at 1 year, 9264 in group A (95.6%) and 423 in group B (4.4%). Both groups were similar regarding dyslipidemia, diabetes mellitus, previous coronary artery disease, multivessel disease after the cardiac catheterization. Group A had more smokers (28.2 vs 17.8%, p < 0.001) and left ventricular ejection fraction (LVEF) >50% (69.2 vs 45.1%, p < 0.001). On the other hand, group B was elderly (67 ± 14 vs 75 ± 12, p < 0.001), female (26.9 vs 34.0%, p < 0.001), arterial hypertension (70.5 vs 77.5%, p = 0.005), was more admitted directly to the cat lab (12.5 vs 17.7%, p = 0.002), ST-segment elevation myocardial infarction (40.2 vs 49.9%, p < 0.001), Killip-Kimball classification > I (12.8 vs 34.8%, p < 0.001) and hybrid revascularization (0.7 vs 2.4%, p = 0.002). Logistic regression revealed that new-onset of AF in ACS patients was a predictor of congestive heart failure (odds ratio (OR) 1.75, p < 0.001, confidence interval (CI) 1.47-2.09), cardiogenic shock (OR 3.08, p < 0.001, CI 2.37-4.01), sustained ventricular tachycardia (OR 2.29, p < 0.001, CI 1.61-3.25) and intrahospital mortality (OR 1.99, p < 0.001, CI 1.51-2.63). Nevertheless, new-onset of AF was not associated with re-infarction (p = 0.361), mechanical complications (p = 0.319), atrioventricular block (p = 0.574), stroke (p = 0.131) and cardiac arrest (p = 0.060) during the hospitalization for ACS. Mortality rates at one year of follow-up showed significant differences, p < 0.001, between the two groups (Figure 1). Similar results were found concerning re-admission for all causes, p = 0.021 (Figure 2), on the other causes, re-admission for cardiovascular causes do not reveal to be significant, p = 0.515.
Conclusions
New-onset of AF in ACS was a predictor of congestive heart failure, cardiogenic shock, sustained ventricular tachycardia and intrahospital mortality. AF was associated with higher mortality rates and re-admission for all causes at one year follow up.

Methods
Multicenter retrospective study, based on the Portuguese Registry of ACS between 1/10/2010-3/05/2020. Patients were divided into two groups: A – patients without AVB, and B – patients that presented AVB. Were excluded patients without a previous cardiovascular history or clinical data regarding AVB occurrence. Logistic regression was performed to assess predictors of AVB in ACS patients.
Results
From 32157 patients, 23774 was included, 23148 in group A (97.4%) and 626 in group B (2.6%). Both groups were similar regarding initial symptons until first medical contact (p = 0.410), smoker status (p = 0.222), arterial hypertension (p = 0.776), diabetes mellitus (p = 0.508), peripheral artery disease (p = 0.479), chronic kidney disease (p = 0.467) and re-infarction during the hospitalization for ACS (p = 0.145).

Logistic regression revealed that female gender (odds ratio (OR) 1.422, p = 0.015, confidence interval (CI) 1.072-1.885), age ≥75 years old (OR 1.560, p = 0.002, CI 1.174-2.073), heart rate <60 (OR 6.692, p < 0.001, CI 5.180-8.644) and Killip-Kimball class > I (OR 3.264, p < 0.001, CI 2.446-5.356) were predictors of AVB in ACS patients.
Conclusions
Female gender, age ≥75 years old, heart rate <60 and Killip-Kimball class > I were predictors of AVB in ACS patients.

Background
Cardiovascular risk factors (CVRF) are a growing health problem in developed countries, being directly associated with acute coronary syndrome (ACS) occurrence and atrial fibrillation (AF). Nevertheless, new onset of AF in context of ACS is a clinical problem with prognostic and therapeutic implications.
Objective
Evaluate the impact of the CVRF in new onset AF during the hospitalization for ACS.
Methods
Multicenter retrospective study, based on the Portuguese Registry of ACS between 1/10/2010-4/09/2019. Patients were divided in two groups: A – without new onset of AF during the hospitalization for ACS and B – with new onset of AF during the hospitalization for ACS. CVFR was defined by body mass index, diabetes, arterial hypertension, smoking, coronary artery disease, neoplasia, dyslipidemia, chronic kidney disease and peripheral arterial disease. Logistic regression was performed to assess predictors of new onset AF in these patients.
Results
14037 patients were included, 637 in group B (4.8%). Both groups were similar regarding diabetes mellitus (p = 0.116), coronary artery disease (p = 0.264) and neoplasia (p = 0.327). Curiously the group A exhibited higher body mass index (27.5 ± 4.3 vs 27.2 ± 4.4, p < 0.001), smokers (28.1 vs 18.5%, p < 0.001) and dyslipidemia (62.8 vs 56.7%, p < 0.001). On the other hand, group B presented more females (26.4 vs 35.0%, p < 0.001), arterial hypertension (70.0 vs 74.9%, p = 0.002), peripheral arterial disease (5.4 vs 8.4%, p < 0.001) and chronic kidney disease (6.7 vs 9.5%, p < 0.001). Logistic regression revealed that body mass index, smoker status, diabetes, dyslipidemia, coronary artery disease, neoplasia, chronic kidney disease and peripheral arterial disease were not predictors of AF during the hospitalization for ACS. Nonetheless, female gender (odds ratio (OR) 1.23, p = 0.025, confidence interval (CI) 1.03-1.47), obesity (OR 1.39, p = 0.004, CI 1.11-1.74) and arterial hypertension (OR 1.22, p = 0.049, CI 1.01-1.50) were predictors of new onset of AF during hospitalization for ACS. Conclusions: Female gender, obesity and arterial hypertension were predictors of new onset of AF in during hospitalization for ACS.

Portuguese Registry of Acute Coronary Syndromes
Background
Cardiovascular risk factors (CVRF) are a growing health problem in developed countries. These patients have a higher prevalence of acute coronary syndromes (ACS) and as a consequence ACS complication, like heart failure (HF). HF after an ACS is a common complication and CVFR can influence its manifestation.
Objective
Evaluate the impact of the CVRF in HF during the hospitalization for ACS.
Methods
Multicenter retrospective study, based on the Portuguese Registry of ACS between 1/10/2010-4/09/2019. Patients were divided in two groups: A – without new onset of HF during the hospitalization for ACS and B – with new onset of HF during the hospitalization for ACS. CVFR was defined by body mass index, diabetes, arterial hypertension, smoking, neoplasia, dyslipidemia, coronary artery disease, chronic kidney disease and peripheral arterial disease. Logistic regression was performed to assess predictors of new onset HF in these patients.
Results
14717 patients were included, 2287 in group B (15.5%). Both groups were similar regarding body mass index (27.5 ± 4.3 vs 27.2 ± 4.4, p = 0.254). Curiously the group A exhibited higher prevalence of smoking status (29.8 vs 16.6%, p < 0.001). On the other hand, group B presented more females (25.0 vs 35.7%, p < 0.001), arterial hypertension (68.7 vs 78.2%, p < 0.001), diabetes mellitus (28.5 vs 43.1%, p < 0.001), dyslipidemia (62.2 vs 64.3%, p = 0.023), coronary artery disease (19.6 vs 25.6%, p < 0.001), neoplasia (4.4 vs 7.0%, p < 0.001), peripheral arterial disease (5.2 vs 15.8%, p < 0.001) and chronic kidney disease (4.6 vs 10.0%, p < 0.001). Logistic regression revealed that body mass index, diabetes, arterial hypertension, neoplasia and dyslipidemia were not predictors of HF during the hospitalization for ACS. Nevertheless, female gender (odds ratio (OR) 1.37, p < 0.001, confidence interval (CI) 1.22-1.54), chronic kidney disease (OR 1.59, p < 0.001, CI 1.33-1.90) and peripheral arterial disease (OR 1.54, p < 0.001, CI 1.27-1.86) were predictors of new onset of HF during hospitalization for ACS. Curiously, smoking seems to have a protective effect (OR 0.68, p < 0.001, CI 0.59-0.78) in new onset HF in ACS patients.
Conclusions
Chronic kidney disease and peripheral arterial disease were predictors of new onset of HF in during hospitalization for ACS.

Portuguese Registry of Acute Coronary Syndromes
Background
The presence of cardiovascular risk factors (CVRF) are directly related to acute coronary syndrome (ACS) occurrence. ACS is a major health problem with multiple complications. Completed atrioventricular block (CAVB) in context of ACS can impact the patient’s prognosis, and is not clarified if its presence can be predicted only by CVFR.
Objective
Evaluate the impact of the CVRF in CAVB during the hospitalization for ACS.
Methods
Multicenter retrospective study, based on the Portuguese Registry of ACS between 1/10/2010-4/09/2019. Patients were divided in two groups: A – without CAVB during the hospitalization for ACS and B – with CAVB during the hospitalization for ACS. CVFR was defined by body mass index, diabetes, arterial hypertension, smoking, coronary artery disease, neoplasia, dyslipidemia, chronic kidney disease and peripheral arterial disease. Logistic regression was performed to assess predictors of CAVB in these patients.
Results
14031 patients were included, 401 in group B (2.9%). Both groups were similar regarding smoking status (p = 0.920), arterial hypertension (p = 0.928), diabetes mellitus (p = 0.249), peripheral arterial disease (p = 0.352) and chronic kidney disease (p = 0.783). Interestingly the group A exhibited higher body mass index (27.4 ± 4.3 vs 26.9 ± 4.5, p < 0.001), dyslipidemia (62.8 vs 53.6%, p < 0.001) and coronary artery disease (20.7 vs 15.0%, p = 0.001). On the other hand, group B presented more females (26.7 vs 31.5%, p = 0.012), mean age (66 ± 13 vs 71 ± 13, p < 0.001) and neoplasia (4.8 vs 7.1%, p = 0.012). Logistic regression revealed that any of the CVRF were a predictor of CAVB during the hospitalization for ACS. Just, age (odds ratio 1.48, p < 0.001, confidence interval 1.16-1.88) has been a predictor of CAVB during hospitalization for ACS.
Conclusions
Any CVFR was a predictor of CAVB in context of ACS. Age was a predictor of CAVB during hospitalization for ACS.

Abstract
Abstract
Background
Mammographic density (MD)-the amount of radio-dense fibroglandular tissue seen on a mammogram - is a stronger biomarker of susceptibility to breast cancer and a major determinant of the sensitivity of mammographic screening. This study examined for the first time racial differences in MD in Brazil.
Methods
555 women (215 from the Longitudinal Study of Adult Health - ELSA-Brasil and 340 users of the Unified Health System - SUS) in Bahia were enrolled into the study. Participants completed an interview, had their heights and weights measured, and underwent a 2-view (cranio-caudal (CC) and medio-lateral-oblique (MLO)) digital mammography of each breast. MD was measured on the left MLO image using the semi-automated Cumulus software, and expressed as the percentage (PMD) of the breast area occupied by fibroglandular tissue. Linear regression models were fitted to assess ethnicity-PMD associations adjusting for age at mammography, body mass index (BMI) and reading batch (minimally-adjusted) and further for socio-economic and reproductive variables.
Results
The study population comprised 95 White (W), 270 Brown-mixed (Bm) and 169 Black (B) women, with a mean age at mammography of 58 (SD = 5.4) years. 63% W, 69% Bm and 49% B women had low educational level; 24% W, 47% Bm and 31% B women had ≥4 children. Minimally-adjusted analysis showed that relative to W women, PMD was 23% (1.23; 95% CI 1.04-1.45) higher in Bm and 4% (1.04; 0.89-1.21) higher in B; however, further adjustment for socio-economic and reproductive variables attenuated the racial differences (fully-adjusted model: 16% (1.16; 0.96-1.40) and 9% (1.09; 0.92-1.29) for Bm and B, respectively.
Conclusions
The racial differences in PMD were mainly accounted by ethnic differences in socio-economic and reproductive-related factors.
Implications Further studies should examine whether racial differences in PMD in Brazil lead to racial differences in false negative and interval cancer rates of mammographic screening.
Key messages
In Brazil, ethnic differences in socio-economic and reproductive-related factors are responsible for racial differences in mammographic density. More research is needed to address racial differences in breast cancer risk in Brazil.

Abstract
Deep brain stimulation is an established therapy for multiple brain disorders, with rapidly expanding potential indications. Neuroimaging has advanced the field of deep brain stimulation through improvements in delineation of anatomy, and, more recently, application of brain connectomics. Older lesion-derived, localizationist theories of these conditions have evolved to newer, network-based "circuitopathies," aided by the ability to directly assess these brain circuits in vivo through the use of advanced neuroimaging techniques, such as diffusion tractography and fMRI. In this review, we use a combination of ultra-high-field MR imaging and diffusion tractography to highlight relevant anatomy for the currently approved indications for deep brain stimulation in the United States: essential tremor, Parkinson disease, drug-resistant epilepsy, dystonia, and obsessive-compulsive disorder. We also review the literature regarding the use of fMRI and diffusion tractography in understanding the role of deep brain stimulation in these disorders, as well as their potential use in both surgical targeting and device programming.

Abstract
BACKGROUND AND PURPOSE Deep brain stimulation is a well-established treatment for generalized dystonia, but outcomes remain variable. Establishment of an imaging marker to guide device targeting and programming could possibly impact the efficacy of deep brain stimulation in dystonia, particularly in the absence of acute clinical markers to indicate benefit. We hypothesize that the stimulation-based functional and structural connectivity using resting-state fMRI and DTI can predict therapeutic outcomes in patients with generalized dystonia and deep brain stimulation. MATERIALS AND METHODS We performed a retrospective analysis of 39 patients with inherited or idiopathic-isolated generalized dystonia who underwent bilateral globus pallidus internus deep brain stimulation. After electrode localization, the volumes of tissue activated were modeled and used as seed regions for functional and structural connectivity measures using a normative data base. Resulting connectivity maps were correlated with postoperative improvement in the Unified Dystonia Rating Scale score. RESULTS Structural connectivity between the volumes of tissue activated and the primary sensorimotor cortex was correlated with Unified Dystonia Rating Scale improvement, while more anterior prefrontal connectivity was inversely correlated with Unified Dystonia Rating Scale improvement. Functional connectivity between the volumes of tissue activated and primary sensorimotor regions, motor thalamus, and cerebellum was most correlated with Unified Dystonia Rating Scale improvement; however, an inverse correlation with Unified Dystonia Rating Scale improvement was seen in the supplemental motor area and premotor cortex. CONCLUSIONS Functional and structural connectivity with multiple nodes of the motor network is associated with motor improvement in patients with generalized dystonia undergoing deep brain stimulation. Results from this study may serve as a basis for future development of clinical markers to guide deep brain stimulation targeting and programming in dystonia.

Introduction
Constrictive pericarditis (CP) is a rare etiology of heart failure. Is a chronic inflammatory process, characterized by scarring, fibrosis and pericardial calcification. Several etiologies can be associated with CP, namely infectious, idiopathy and post-surgical. In some cases, CP can extend to the myocardium and/or lead to cardiac dysfunction.
Case Report
58 years old woman, active smoking, referred to the emergency room for tachycardia on a routine electrocardiogram. History of 5 months of fatigue and dyspnea to ordinary activities, with progressive aggravation in the last month, associated with weight loss and episodic palpitations. Upon the physical examination presented jugular vein engorgement and peripheral edema. Admission electrocardiogram with atrial flutter at 150 of ventricular frequencies, without other findings. Thoracic radiography without variation (tenues pericardium enhancement), abdominal echography with moderate ascites. Blood work showed elevated liver enzymes, BNP of 230pg/ml, exclusion of infectious tuberculosis and autoimmune panel with isolated positive rheumatoid factor. Transthoracic echocardiography (TTE) at the emergency room show a non-dilated and global left ventricle hypokinesia, with reduced left ventricular ejection fraction (LVEF) and dilatation of the mitral valve ring in the genesis of moderate mitral regurgitation. Anticongestive and antiarrhythmic therapy started with rhythm conversion and clinical improve. Thoracic computed tomography scan reveals an extensive pericardial calcification. 2 months later TTE reveal a preserved LVEF, pericardial calcification, moderate mitral regurgitation, grade III diastolic dysfunction, respiration-related ventricular septal shift, increased of the mitral E-wave velocity with an E/A of 2.76, the peak mitral E-wave decreases 36% with the inspiration, dilated inferior vena cava without respiratory variation. Cardiac magnetic resonance imaging exposes a septal bounce and pericardial calcification, suggestive signs of constrictive pericarditis. The patient waits for cardiac catheterization for confirmation, being with anticoagulation, ACE inhibitors, beta-blockers and mineralocorticoid receptor antagonist medication, remaining in NYHA class I.
Discussion
Clinical suspicion of CP is key for its identification, since there is not a specific clinical manifestation and generally patients presented heart failure symptoms. Echocardiography is best tool for a clinical physician evaluate heart failure etiologies, and can be used with higher sensitivity and specificity associated to the correct criteria to the diagnosis of CP. Pericardiectomy is the standard treatment, however the moment of its performance is not well established, since patients can remain in NYHA class I several years and the surgical procedure have higher mortality rates.

Abstract
OBJECTIVES To investigate the incidence of inherited thrombophilias in patients with adverse obstetric outcomes and to compare detection rates of thrombophilias between standard blood tests and a novel genetic test. METHODS This is a case-control prospective study performed in Hospital Sant Joan de Déu in Barcelona, Spain. Cases had a history of intrauterine growth restriction requiring delivery before 34 weeks gestation, placental abruption before 34 weeks gestation, or severe preeclampsia. Controls had at least two normal, spontaneously conceived pregnancies at term, without complications or no underlying medical disease. At least 3 months after delivery, all case and control women underwent blood collection for standard blood tests for thrombophilias and saliva collection for the genetic test, which enables the diagnosis of 12 hereditary thrombophilias by analyzing genetic variants affecting different points of the blood coagulation cascade. RESULTS The study included 33 cases and 41 controls. There were no statistically significant differences between cases and controls in the standard blood tests for thrombophilias in plasma or the TiC test for genetic variables. One clinical-genetic model was generated using variables with the lowest P values: ABO, body mass index, C_rs5985, C_rs6025, and protein S. This model exhibited good prediction capacity, with an area under the curve of almost 0.7 (P <0.05), sensitivity of almost 67%, and specificity of 70%. CONCLUSION Although some association may exist between hypercoagulability and pregnancy outcomes, no significant direct correlation was observed between adverse obstetric outcomes and inherited thrombophilias when analyzed using either standard blood tests or the genetic test. Future studies with a larger sample size are required to create a clinical-genetic model that better discriminates women with a history of adverse pregnancy outcomes and an increased risk of poor outcomes in subsequent pregnancies.

Abstract
SETTING University-affiliated hospital located in Porto, North Portugal, an area with a low to intermediate incidence of tuberculosis (TB). OBJECTIVE To identify predictors and outcomes of disseminated TB (dTB). DESIGN A cohort of patients diagnosed with TB between 2007 and 2013 was retrospectively analysed. Patients with dTB criteria were characterized and compared to single organ TB cases. Factors independently associated with dTB were determined by multivariate logistic regression analysis. RESULTS A total of 744 patients were analysed, including 145 with dTB. Independent risk factors for dTB were pharmacological immunosuppression (OR 5.6, 95% CI 2.8-11.3), HIV infection (OR 5.1, 95% CI 3.1-8.3), chronic liver failure or cirrhosis (OR 2.3, 95% CI 1.4-4.1) and duration of symptoms (OR 2.3, 95% CI 1.4-3.8). Compared to single organ TB, the clinical presentation of dTB patients differed by the absence of haemoptysis (OR 3.2, 95% CI 1.3-8.4) and of dyspnoea (OR 1.9, 95% CI 1.2-3.1), presence of weight loss (OR 1.8, 95% CI 1.1-2.9), night sweats (OR 1.7, 95% CI 1.1-2.7) and bilateral lung involvement (OR 4.4, 95% CI 2.8-7.1). Mortality and time until culture conversion were higher for dTB patients, although not reaching statistical significance. CONCLUSION Immunosuppressive conditions and chronic liver failure or cirrhosis were associated with increased risk of dTB. The haematogenous spread may be dependent on longer symptomatic disease and usually progresses with bilateral lung involvement.

Abstract
Background and objective Approximately half of the population will experience either low back pain or neck pain, at some point in their lives. Previous studies suggest that people with diabetes are more likely to present with chronic somatic pain, including shoulder, knee and spinal pain. This study aimed to systematically review and appraise the literature to explore the magnitude as well as the nature of the association between diabetes and back, neck, or spinal (back and neck) pain. Databases and data treatment A systematic search was performed using the Medline, CINAHL, EMBASE, and Web of Science electronic databases. Studies which assessed the association between diabetes and back or neck pain outcomes, in participants older than 18 years of age were included. Two independent reviewers extracted data on the incidence of pain and reported associations. Results Eight studies were included in the meta-analyses. Meta-analyses showed that people with diabetes are more likely to report low back pain [5 studies; n: 131,431; odds ratio (OR): 1.35; 95% Confidence Interval (CI): 1.20 to 1.52; p<0.001] and neck pain (2 studies; n: 6,560; OR: 1.24; 95% CI: 1.05 to 1.47; p = 0.01) compared to those without diabetes. Results from one longitudinal cohort study suggested that diabetes is not associated with the risk of developing future neck, low back or spinal pain. Conclusions Diabetes is associated with low back and neck individually, and spinal pain. The longitudinal analysis showed no association between the conditions. Our results suggest that diabetes co-exists with back pain; however, a direct causal link between diabetes and back pain was not established.

Abstract
BACKGROUND AND PURPOSE Although globus pallidus internus deep brain stimulation is a widely accepted treatment for Parkinson disease, there is persistent variability in outcomes that is not yet fully understood. In this pilot study, we aimed to investigate the potential role of globus pallidus internus segmentation using probabilistic tractography as a supplement to traditional targeting methods. MATERIALS AND METHODS Eleven patients undergoing globus pallidus internus deep brain stimulation were included in this retrospective analysis. Using multidirection diffusion-weighted MR imaging, we performed probabilistic tractography at all individual globus pallidus internus voxels. Each globus pallidus internus voxel was then assigned to the 1 ROI with the greatest number of propagated paths. On the basis of deep brain stimulation programming settings, the volume of tissue activated was generated for each patient using a finite element method solution. For each patient, the volume of tissue activated within each of the 10 segmented globus pallidus internus regions was calculated and examined for association with a change in the Unified Parkinson Disease Rating Scale, Part III score before and after treatment. RESULTS Increasing volume of tissue activated was most strongly correlated with a change in the Unified Parkinson Disease Rating Scale, Part III score for the primary motor region (Spearman r = 0.74, P = .010), followed by the supplementary motor area/premotor cortex (Spearman r = 0.47, P = .15). CONCLUSIONS In this pilot study, we assessed a novel method of segmentation of the globus pallidus internus based on probabilistic tractography as a supplement to traditional targeting methods. Our results suggest that our method may be an independent predictor of deep brain stimulation outcome, and evaluation of a larger cohort or prospective study is warranted to validate these findings.

Abstract
Background In a phase II study, topotecan was evaluated for response and toxicity in patients with advanced pancreatic carcinoma at the schedule of 0.7 mg/m2/day q 21 days q 28 days. Methods Responses were assessed after at least 2 courses using WHO criteria, and toxicity was evaluated after each course according to the CTC-NCI standards. Between December 1995 and September 1997, 15 assessable patients (median age, 55 years; range, 36-74; median ECOG performance, 1; range, 0-3) were included in the study. All had biopsy-proven and measurable disease, a life-expectancy of at least 3 months, and normal bone marrow, liver, and renal function. None of the patients had undergone prior cytotoxic or radiation therapy, and 10 were initially treated by surgery. Twenty-five cycles were assessable for toxicity. Plasma was collected from 7 patients who had received a total of 10 cycles and was, after extraction with methanol at −20°C, analyzed for total topotecan by an HPLC method. The thus determined steady-state concentrations were assessed for their capacity to affect growth and DNA integrity in the BxPC-3 human pancreatic carcinoma cell line after 21 days of continuous exposure. For these purposes, we used a sulforhodamine B staining assay, and agarose gel electrophoresis, respectively. Results Grades 3-4 leukopenia, thrombocytopenia, granulocytopenia, and anemia occurred in 8, 6, 8 and 8 cycles, respectively. Other mild to moderate side effects (grades 1-2) included malaise, nausea and vomiting, anorexia, and alopecia. No objective tumor response was documented. HPLC analysis of patients' plasma showed the attainment of constant steady-state levels of 1.0 ± 0.1 ng/mL during the entire infusion period. At such a concentration, topotecan did not significantly affect growth or DNA integrity in the BxPC-3 cells. Fifty percent cell growth inhibition and appreciable oligonucleosomal DNA fragmentation were only evident with 21 days topotecan ≥ 50 ng/mL. Conclusions Our data suggest that the lack of clinical activity of 0.7 mg/m2 daily topotecan for 21 days q 28 days in patients with advanced pancreatic carcinoma might be partially attributed to the achievement of non-tumoricidal plasma drug concentrations.

Abstract
AIM To evaluate if the redox system is unbalanced in the hearts of nitrofen-induced congenital diaphragmatic hernia (CDH) animals and to study the possible preventive effects of two anti-oxidant treatments, apocynin and epigallocatechin-3-gallate (EGCG). METHODS Adult rats were divided into four groups. Group 1: rats received only vehicle on day E9.5. Group 2: rats received 100 mg nitrofen on day E9.5. Group 3: 1 month before mating rats received apocynin 1.5 mM and, when pregnant, 100 mg nitrofen on day E9.5. Group 4: same than group 3 but with EGCG 30 mg/kg. All fetuses were recovered at term and the hearts were processed. Nox activity and mRNA levels of Nox1, Nox2, Nox4, SOD1, SOD2, SOD3, catalase, and GPX1 were analyzed. Nox, SOD, and Catalase activity and H2O2 production were also evaluated. RESULTS Nox activity, H2O2 production and Nox1, Nox2, and Nox4 mRNA levels were increased in the hearts of fetuses with CDH. There were no changes in SOD1 levels, whereas those of SOD2, SOD3, catalase, and GPX1 mRNA were decreased. Apocynin and EGCG treatments attenuated the increment of Nox and SOD activities and H2O2 production was only decreased by apocynin. CONCLUSION These findings suggest a possible preventive effect on the abnormal redox metabolism of anti-oxidant treatments in the hearts from rat fetuses with CDH. If the same occurs in humans, it could represent a potential tool in future prenatal treatment.

Abstract
PURPOSE To evaluate the macular choroidal thickness (CT) of eyes subjected to pars plana vitrectomy (PPV) whether or not combined with encircling scleral buckling (ESB) surgery for primary rhegmatogenous retinal detachment repair at 6 months or more after surgery. METHODS This observational study included: 15 eyes (15 patients) submitted to combined ESB+PPV; 15 eyes submitted to PPV and their respective 30 normal fellow eyes (FE). Two 6mm lineal perpendicular optical coherence tomography B-scans centred on the fovea with enhanced depth imaging were performed on each eye. CT was measured at several macular locations: subfoveal (SF-CT) and at a radius of 1, 2, and 3mm from the fovea. CTs of the eyes in the CE+PPV group were compared to CT in the PPV group and the CTs of all operated eyes were compared to the CTs of their FE. RESULTS SF-CT of the eyes in the ESB+PPV group was significantly increased compared to their FE (P=.001). CT at a radius of 1, 2, and 3mm from the fovea of the ESB+PPV group were significantly increased (P=.001, P=.005, and P=.001, respectively). The SF-CT of the PPV group was similar to their FE (P=.691). The SF-CT of the ESB+PPV group was significantly increased compared to SF-CT of the PPV group (P=.019). CONCLUSIONS The CT of the eyes subjected to combined ESB and PPV was significantly increased at 6 months or more after surgery compared to the CT of their FE and to the CT of the eyes subjected to PPV alone, which could be explained by a venous engorgement caused by the ESB.

Abstract
BACKGROUND Telehealth has emerged as a potential alternative to deliver interventions for low back pain (LBP); however, its effectiveness has not been investigated. PURPOSE The aim of this review was to evaluate whether interventions delivered by telehealth improve pain, disability, function, and quality of life in non-specific LBP. STUDY DESIGN This is a systematic review with meta-analysis. METHODS Seven databases were searched from the earliest records to August 2015. Eligible studies were randomized controlled trials that investigated the effectiveness of telehealth-based interventions, solo or in combination with other interventions, for non-specific LBP compared with a control group. Trials deemed clinically homogeneous were grouped in meta-analyses. RESULTS Eleven studies were included (n=2,280). In chronic LBP, telehealth interventions had no significant effect on pain at short-term follow-up (four trials: 1,089 participants, weighted mean difference [WMD]: -2.61 points, 95% confidence interval [CI]: -5.23 to 0.01) or medium-term follow-up (two trials: 441 participants, WMD: -0.94 points, 95% CI: -6.71 to 4.84) compared with a control group. Similarly, there was no significant effect for disability. Results from three individual trials showed that telehealth was superior to a control intervention for improving quality of life. Interventions combining telehealth and usual care were more beneficial than usual care alone in people with recent onset of LBP symptoms. CONCLUSION There is moderate-quality evidence that current telehealth interventions, alone, are not more effective than minimal interventions for reducing pain and disability in chronic LBP. To date, modern telehealth media (eg, apps) and telehealth as an adjunct to usual care remain understudied.

Abstract
The increase in prevalence of obesity in industrialized societies is an indisputable fact. However, the apparent passive role played by adipocytes, in pathophysiological terms, has been gradually substituted by a metabolically active performance, relevant to many biochemical mechanisms that may contribute to a chronic low-grade inflammatory status, which increasingly imposes itself as a key feature of obesity. This chronic inflammatory status will have to be integrated into the complex equation of many diseases in which inflammation plays a crucial role. Multiple sclerosis (MS) is a chronic inflammatory condition typically confined to the central nervous system, and many work has been produced to find possible points of contact between the biology of this immune-mediated disease and obesity. So far, clinical data are not conclusive, but many biochemical features have been recently disclosed. Brain inflammation has been implicated in some of the mechanisms that lead to obesity, which has also been recognized as an important player in inducing some degree of immune dysfunction. In this review, we collected evidence that allows establishing bridges between obesity and MS. After considering epidemiological controversies, we will focus on possible shared mechanisms, as well as on the potential contributions that disease-modifying drugs may have on this apparent relationship of mutual interference.

OBJECTIVE Pain exacerbated by movement and loading on the joint is the major symptom of osteoarthritis (OA), but the mechanisms of chronic pain in this pathology are still poorly understood. Using the intra-articular (i.a.) injection of collagenase in the knee of rats as a model of OA, we aimed at evaluating whether injury of sensory neurons may contribute to the development of OA-associated nociception. DESIGN OA was induced by i.a. injection of collagenase into the left knee joint of adult male Wistar rats. Histopathological changes and movement and loading-induced nociception were assessed for 6 weeks. A time-course analysis of the expression of the neuronal injury markers activating transcription factor-3 (ATF-3) and neuropeptide Y (NPY) and of the neuropeptide SP in the dorsal root ganglion (DRG) was performed. Gabapentin's effect on nociception was evaluated, as well as the expression of the α2δ-1 voltage-gated calcium channel subunit. RESULTS Collagenase induced the development of OA-like histopathological changes and of movement-induced nociception. Altered expression of ATF-3, NPY and SP was observed in the DRG, correlating with the degree of articular degeneration after 6 weeks of disease progression. Repeated administration of gabapentin reversed the nociceptive responses 6 weeks after the induction of OA. α2δ-1 was upregulated in the DRG. CONCLUSION By inducing nociceptive behaviours associated with relevant joint structural changes, the i.a. injection of collagenase presents itself as a pertinent model for the study of OA pain. The findings in this study support the hypothesis that injury of sensory neurons innervating OA joints may be a significant element in the mechanisms of OA-associated pain.
