Abstract Background The 2016 J Wave Syndrome Consensus Report proposed the Shanghai Brugada Syndrome (BS) Score, a diagnostic score based on ECG features, genetic results, family and clinical history. Purpose The aim of our study was to reclassify our institution's BS cohort using the Shanghai BS Score. Methods We collected 170 patients with BS diagnosis (according to guidelines) who attended our outpatient clinic between 1996 and 2019. Patients were followed on an yearly basis. During follow up (FU) we looked for the appearance of a spontaneous Type 1 ECG (either with a 12 lead ECG or a 12 lead Holter monitoring) and arrhythmic events (defined as unexplained cardiac arrest or documented VF/polymorphic VT, nocturnal agonal respirations, syncope, atrial flutter/fibrillation). Genetic analysis, limited to SCN5A and SCN1B variants, was performed. We examined each item of the Shanghai BS Score at the first and the last visit at our hospital. Results At baseline all patients presented a type 1 ECG: 26 (15%) spontaneously, 2 (1%) during a febrile illness and 142 (84%) after ajmaline pharmacological challenge. 158 (93%) patients were asymptomatic while 12 (7%) presented symptoms: 1 unexplained cardiac arrest, 1 nocturnal agonal respirations, 9 syncopes, 1 atrial flutter/fibrillation under the age of 30 years. Genetic testing was performed in 73 (43%) patients; an SCN5A mutation was detected in 11 patients while a SCN1B was detected in 1 patient. According to the score we divided the patients as follows: group A 2 to 3 points 107 (63%) patients; group B 3.5 points 13 (8%) patients; group C 4 to 5 points 39 (23%) patients; group D ≥5.5 points 11 (6%) patients. During FU (medium 59 months) there were 3 (2.8%) arrhythmic events in group A (2 unexplained cardiac arrests and 1 syncope; 0 in group B; 1 (2.6%) in group C (syncope); 3 (27%) in group D (1 FV and 2 syncopes). 19 patients (11%) modified their Shanghai score during FU: 16 because of the appearance of a spontaneous type 1 ECG, 3 for their clinical history. Conclusions Although the Shanghai Score has been proposed as a diagnostic tool, data from literature show that patients with a higher score are at a progressively higher risk for VT/VF. Unexpectedly, we observed 2 unexplained cardiac arrests in the group of patients with a score 2 to 3. This may suggest the need to the use other risk criteria such as fractionated potentials or other ECG markers. Additionaly, we have shown that this Score is prone to changes over time, stressing the importance of a regular FU with continuous risk assessment.

Abstract Background Left ventricular systolic dysfunction (LVSD) is common after out of hospital cardiac arrest (OOHCA) and can manifest as global or regional change. Purpose We evaluated the extent of global and regional LVSD and its association with coronary artery disease (CAD) and outcome in those undergoing coronary angiography after OOHCA. Methods 619 patients with OOHCA were admitted at our centre between 1st May 2012 and 31st December 2017. 398 patients were included. Rates of cardiogenic shock and extent of CAD, as classified by the SYNTAX score were measured. The primary endpoint was 12-month mortality. Patients with incomplete data were excluded from the analysis. Results Two hundred and sixty-six patients (median age 62 [53–71] 76.3% male) underwent both trans-thoracic echocardiography andcoronary angiography on arrival and were included in the final analysis. 81.6% had ventricular fibrillation, 83.5% were witnessed and 51.9% occurred at residence. Ninety-six patients (36%) had significant LVSD (Left Ventricular Ejection Fraction [LVEF] <40%) and 139 (52.2%) patients had regional wall motion abnormalities (RWMAs) on arrival. Patients were classified into 4 groups (Group A: LVEF <40%/Global, Group B: LVEF <40%/RWMA, Group C: LVEF ≥40%/Global and Group D: LVEF ≥40%/RWMA) with frequencies of 10.9%, 25.2%, 41.4% and 22.6%). Patients in Group D had the shortest low-flow times and lowest rates of epinephrine administration, with most favourable metabolic status on arrival, based on lactate and creatinine values. In Groups B and D (RWMAs), patients were significantly more likely to have a post-ROSC ECG demonstrating ST elevation/LBBB and absence of epinephrine administration during resuscitation with shorter low flow times. Extent of CAD was similar between the four groups. From patients with LVEF ≥40%, patients in Group C had substantially lower SYNTAX scores than compared with Group D (0.5 vs 13.5, p<0.001). However, both Group B and C (RWMA) groups had highest rates of culprit lesions compared with matched global groups which was reflected in higher PCI rates (Figure 1). The primary endpoint of 12-month mortality was lowest in Group D and highest in the Group A group. A similar effect was observed for poor neurological outcome and 30-day mortality. Patients with regional LVSD had significantly improved survival at 12 months compared with those with global LVSD (70.5% vs 48.3%, p<0.001) vs 51). Those in Group D had highest survival at 12 months, while this was similar for Groups B and C and lowest in Group A (Figure 2). Cardiac aetiology death was significantly higher in those with LVEF <40% compared to those with LVEF ≥40% (70.5% vs 48.3%, p<0.001). Conclusions Patients with significant LVEF <40% have higher rates of cardiogenic shock and mortality which was driven by cardiac aetiology death, while presence of RWMAs are associated with a higher rate of culprit coronary lesions and improved outcome FUNDunding Acknowledgement Type of funding sources: None.

Abstract Background The decision to terminate resuscitation efforts can be challenging. Notably, the association between duration of resuscitation and long-term survival and functional outcomes after in-hospital cardiac arrest (IHCA) is unknown. Purpose To examine 30-day and 1-year survival stratified by duration of resuscitation efforts. Further, to report long term outcome (1-year survival) without anoxic brain damage or nursing home admission among 30-day IHCA survivors. Methods We included all patients with IHCA from 13 Danish hospitals between January 1st, 2013 to December 31st, 2015. Patients were only included if there was clinical indication for a resuscitation attempt. Data on IHCA was obtained from the DANARREST database, which was linked to national registries to retrieve information on patient characteristics, survival, anoxic brain damage and nursing home admission. Patients were stratified into four groups (A-D) according to quartiles of duration of resuscitation efforts: Group A (<5 minutes), group B (5–11 minutes), group C (12–20 minutes) and group D (≥21 minutes). Using multivariable regression analysis, outcomes were standardized for patient age, sex, Charlson Comorbidity Index, witnessed arrest, monitored arrest, cardiopulmonary resuscitation (CPR) prior to arrival of the in-hospital cardiac arrest team and defibrillation. Results The study population comprised of 1868 patients, median age was 74 (1st-3rd quartile [Q1-Q3] 65–81 years) and 65.0% were men. In total, 52.1% (n=973) of the patients achieved return of spontaneous circulation (ROSC). The overall median duration of resuscitation was 12 min (Q1-Q3 5–21 min). The standardized absolute chance of 30-day survival was 63.6% (95% CI 58.0%-69.0%) for group A, 34.0% (95% CI 29.7%-38.2%) for group B, 14.1% (95% CI 10.7%-17.5%) for group C and 9.0% (95% CI 6.8%-11.8%) for group D. Similarly, the chance of 1-year survival was highest for group A (51.5%; 95% CI 46.3%-56.7%) gradually decreasing to 7.0% (95% CI 4.5%-9.5%) in group D (Fig. 1). Among 30-day survivors of an IHCA, the standardized absolute chance of survival without anoxic brain damage or nursing home admission within one-year post-arrest was highest for patients resuscitated in group A (83.2%; 95% CI 78.4%-88.1%), decreasing to 72.3% (95% CI 64.5%-80.0%) in group B, 68.3% (95% CI 55.3%-81.2%) in group C and 71.1% (95% CI 54.2%-88.0%) in group D (Fig. 2). Conclusion Short time to ROSC after in-hospital cardiac arrest is associated with better long-term prognosis. However, the majority of 30-day survivors are alive 1-year post-arrest without anoxic brain damage and without need for nursing home admission despite prolonged resuscitation.

Background: Frozen shoulder is disorder of the connective tissue that limits the normal Range of motion of the shoulder in diabetes, frozen shoulder is thought to be caused by changes to the collagen in the shoulder joint as a result of long term Hypoglycemia. Mobilization is a therapeutic movement of the joint. The goal is to restore normal joint motion and rhythm. The use of mobilization with movement for peripheral joints was developed by mulligan. This technique combines a sustained application of manual technique “gliding” force to the joint with concurrent physiologic motion of joint, either actively or passively. This study aims to find out the effects of mobilization with movement and end range mobilization in frozen shoulder in Type I diabetics. Materials and Methods: 30 subjects both male and female, suffering with shoulder pain and clinically diagnosed with frozen shoulder was recruited for the study and divided into two groups with 15 patients each based on convenient sampling method. Group A patients received mobilization with movement and Group B patients received end range mobilization for three weeks. The outcome measurements were SPADI, Functional hand to back scale, abduction range of motion using goniometer and VAS. Results: The mean values of all parameters showed significant differences in group A as compared to group B in terms of decreased pain, increased abduction range and other outcome measures. Conclusion: Based on the results it has been concluded that treating the type 1 diabetic patient with frozen shoulder, mobilization with movement exercise shows better results than end range mobilization in reducing pain and increase functional activities and mobility in frozen shoulder.

The study was to determine the presence of Classical Swine Fever virus (CSFv), in the meat of vaccinated pigs with the PAV-250 strain and then challenged using the same strain. Five treatment groups were established (each with four pigs). Group A: Pigs thatwere fed with processed hams from negative animals; Group B: Pigs that were fed with processed hams from commercial pigs inoculated with the ALD (reference strain) (titre of 104.0/ml); Group C: Pigs fed with processed hams from pigs infected with the virulent ALD strain (titre of 102.5/ml); Group D: Pigs fed with processed hams from pigs vaccinated with the PAV-250 strain and challenged with the ALD strain (titre of 101.1/ml); and Group E: Pigs fed with processed hams from pigs vaccinated with two doses of the PAV-250 strain and challenged with the ALD strain (negative). Blood samples were taken at d 1, 5, 10, 15 and 20 for biometric analysis. Groups B, C and D manifested clinical signs of CSFv: 40 °C temperature, anorexia, paralysis, vomiting, diarrhea, tremor, hirsute hair and cyanosis. Pigs were slaughtered and necropsies performed to identify lesions in tissues. Results of direct immunofluorescence testing of tissues were positive and the virus was recovered. Under these study conditions, it was found that CSFv resisted the cooking method at 68 °C for 40 min in hams from unvaccinated pigs, and that the virus was able to transmit the disease to healthy unvaccinated pigs, whereas the hams from the vaccinated animals did not transmit the virus.

<b><i>Introduction:</i></b> The aim of this was to describe the predictors of mortality related to COVID-19 infection and to evaluate the association between overweight, obesity, and clinical outcomes of COVID-19. <b><i>Methods:</i></b> We included the patients &#x3e;18 years of age, with at least one positive SARS-CoV-2 reverse transcriptase-polymerase chain reaction. Patients were grouped according to body mass index values as normal weight &#x3c;25 kg/m<sup>2</sup> (Group A), overweight from 25 to &#x3c;30 kg/m<sup>2</sup> (Group B), Class I obesity 30 to &#x3c;35 kg/m<sup>2</sup> (Group C), and ≥35 kg/m<sup>2</sup> (Group D). Mortality, clinical outcomes, laboratory parameters, and comorbidities were compared among 4 groups. <b><i>Results:</i></b> There was no significant difference among study groups in terms of mortality. Noninvasive mechanical ventilation requirement was higher in group B and D than group A, while it was higher in Group D than Group C (Group B vs. Group A [<i>p</i> = 0.017], Group D vs. Group A [<i>p</i> = 0.001], and Group D vs. Group C [<i>p</i> = 0.016]). Lung involvement was less common in Group A, and presence of hypoxia was more common in Group D (Group B vs. Group A [<i>p</i> = 0.025], Group D vs. Group A [<i>p</i> &#x3c; 0.001], Group D vs. Group B [<i>p</i> = 0.006], and Group D vs. Group C [<i>p</i> = 0.014]). The hospitalization rate was lower in Group A than in the other groups; in addition, patients in Group D have the highest rate of hospitalization (Group B vs. Group A [<i>p</i> &#x3c; 0.001], Group C vs. Group A [<i>p</i> &#x3c; 0.001], Group D vs. Group A [<i>p</i> &#x3c; 0.001], Group D vs. Group B [<i>p</i> &#x3c; 0.001], and Group D vs. Group C [<i>p</i> = 0.010]). <b><i>Conclusion:</i></b> COVID-19 patients with overweight and obesity presented with more severe clinical findings. Health-care providers should take into account that people living with overweight and obesity are at higher risk for COVID-19 and its complications.

Background:Cardiovascular disease (CVD) is detected in up to 50% of systemic lupus erythematosus (SLE) patients1and major cause of death2. Even clinically silent SLE patients can develop left ventricular (LV) diastolic dysfunction3. Proper echocardiographic follow up of SLE patients is required.Objectives:To clarify how the prevalence of LV abnormalities changes over follow-up period and identify the associated clinical factors, useful in suspecting LV abnormalities.Methods:29 SLE patients (24 females and 5 men, mean age 52.8±16.3 years, mean disease duration 17.6±14.5 years) were enrolled. All of them underwent echocardiography as the baseline examination and reexamined over more than a year of follow-up period(mean 1075±480 days) from Jan 2014 to Sep 2019. Patients complicated with pulmonary artery hypertension, deep venous thrombosis or pulmonary embolism and underwent cardiac surgery during the follow-up period were excluded. Left ventricular(LV) systolic dysfunction was defined as ejection fraction (EF) < 50%. LV diastolic dysfunction was defined according to ASE/EACVI guideline4. LV dysfunction (LVD) includes one or both of LV systolic dysfunction and LV diastolic function. Monocyte to HDL ratio (MHR) was calculated by dividing monocyte count with HDL-C level.Prevalence of left ventricular abnormalities was analysed at baseline and follow-up examination. Clinical characteristics and laboratory data were compared among patient groups as follows; patients with LV dysfunction (Group A) and without LV dysfunction (Group B) at the follow-up echocardiography, patients with LV asynergy at any point of examination (Group C) and patients free of LV abnormalities during the follow-up period (Group D).Results:At the baseline examination, LV dysfunction (5/29 cases, 13.8%), LV asynergy (6/29 cases, 21.7%) were detected. Pericarditis was detected in 7 patients (24.1%, LVD in 3 patients, LV asynergy in 2 patients) and 2 of them with subacute onset had progressive LV dysfunction, while 5 patients were normal in echocardiography after remission induction therapy for SLE. At the follow-up examination, LV dysfunction (9/29 cases, 31.0%, 5 new-onset and 1 improved case), LV asynergy (6/29 cases, 21.7%, 2 new-onset and 2 improved cases) were detected. Though any significant differences were observed between Group A and Group B at the baseline, platelet count (156.0 vs 207.0, p=0.049) were significantly lower in LV dysfunction group (Group A) at the follow-up examination. Group C patients had significantly higher uric acid (p=0.004), monocyte count (p=0.009), and MHR (p=0.003) than Group D(results in table).Conclusion:LV dysfunction is progressive in most of patients and requires regular follow-up once they developed. Uric acid, monocyte count and MHR are elevated in SLE patients with LV asynergy. Since MHR elevation was reported as useful marker of endothelial dysfunction5, our future goal is to analyse involvement of monocyte activation and endothelial dysfunction in LV asynergy of SLE patients.References:[1]Doria A et al.

Abstract Background Pernicious placenta previa (PPP) can increase the risk of perioperative complications. During caesarean section in patients with adherent placenta, intraoperative blood loss, hysterectomy rate and transfusion could be reduced by interventional methods. Our study aimed to investigate the influence of maternal hemodynamics control and neonatal outcomes of prophylactic temporary abdominal aortic balloon (PTAAB) occlusion for patients with pernicious placenta previa. Methods This was a retrospective study using data from the Peking University People’s Hospital from January 2014 through January 2020. Clinical records of pregnant women undergoing cesarean section were collected. Patients were divided into two groups: treatment with PTAAB placement (group A) and no balloon placement (group B). Group A was further broken down into two groups: prophylactic placement (Group C) and balloon occlusion (group D). Results Clinical records of 33 cases from 5205 pregnant women underwent cesarean section were collected. The number of groups A, B, C, and D were 17, 16, 5 and 12.We found that a significant difference in the post-operative uterine artery embolism rates between group A and group B (0% vs.31.3%, p = 0.018). There was a significant difference in the Apgar scores at first minute between group A and group B (8.94 ± 1.43 vs 9.81 ± 0.75,p = 0.037),and the same significant difference between two groups in the pre-operative central placenta previa (29.4% vs. 0%,p = 0.044), complete placenta previa (58.8% vs 18.8%, p = 0.032),placenta implantation (76.5% vs 31.3%, p = 0.015). We could also observe the significant difference in the amount of blood cell (2.80 ± 2.68vs.10.66 ± 11.97, p = 0.038) and blood plasma transfusion (280.00 ± 268.32 vs. 1033.33 ± 1098.20, p = 0.044) between group C and group D. The significant differences in the preoperative vaginal bleeding conditions (0% vs 75%, p = 0.009), the intraoperative application rates of vasopressors (0% vs. 58.3%, p = 0.044) and the postoperative ICU (intensive care unit) admission rates (0% vs. 58.3%, p = 0.044) were also kept. Conclusions PTAAB occlusion could be useful in reducing the rate of post-operative uterine artery embolism and the amount of transfusion, and be useful in coping with patients with preoperative vaginal bleeding conditions, so as to reduce the rate of intraoperative applications of vasopressors and the postoperative ICU (intensive care unit) admission. In PPP patients with placenta implantation, central placenta previa and complete placenta previa, we advocate the utilization of prophylactic temporary abdominal aortic balloon placement.

Abstract Background How to perform minimally-invasive surgery on Tile C pelvic fractures is very difficult, and it is also a hot topic in orthopedic trauma research. We applied minimally-invasive treatment using an anterior internal fixator combined with sacroiliac screws. Objectives To compare the biomechanical properties of different fixation models in pelvic facture specimens, using an internal fixation system or a steel plate combined with sacroiliac screws. Methods Sixteen fresh adult cadaver pelvic specimens were randomly separated into four groups named A, B, C, and D. The four groups were respectively stabilized using a two-screwed, three-screwed, or four-screwed anterior internal fixator or a steel plate with sacroiliac screws. All models were tested in both standing and sitting positions. Vertical loads of 600 N were applied increasingly. Shifts of bilateral sacroiliac joints and pubis rupture were measured. Results The shifts in sacroiliac joints and pubis rupture in the standing position were all less than 3.5 mm, and the shifts in the sitting position were all less than 1 mm. In the standing position, the results of shifts in the sacroiliac joints were group C < group D < group B < group A. For comparisons between A:B and C:D, P > 0.05. For comparisons between A, B:C, and D, P < 0.05. The results of shifts in pubis ruptures were group D < group C < group B < group A. In the comparison between C:D, P > 0.05; for comparisons between A:B, A:C, A:D, B:C, and B:D, P < 0.05. In the sitting posture, the results of shifts in the sacroiliac joints were group C < group D < group B < group A, and the shifts in the pubis ruptures were group D < group C < roup B < group A. For comparison between C:D, P > 0.05. For comparisons between A:B, A:C, A:D, B:C, and B:D, P < 0.05. Conclusion Use of an anterior internal fixator combined with sacroiliac screws effectively stabilized Tile C3 pelvic fractures. The stability of specimens increased as the number of screws in the internal fixator increased.

Exposure of sheep to Borreliaburgdorferi sensulato (s.I.) complex, the causative agent of Lyme borreliosis (LB), has been reported in tick-abundant areas worldwide, while no data have been reported in Greece. The aim of the study was to identify the hematological alterations in sheep with seropositivity against Borrelia burgdorferi (s.I.). Blood samples were obtained from 318 tick infested sheep for blood analysis and serological determination of IgG and IgM antibodies against B. burgdorferi by indirect immunofluorescence antibody (IFA) assay after exclusion of endo-ectoparasites and other tick-borne infections. A total number of 162 sheep met the inclusion criteria, allocated in four groups based on the presence or absence of IgG and/or IgM; sheep found negative for IgM and IgG (Group A), positive for IgM (Group B), positive for both IgM and IgG (Group C) and positive for IgG (Group D). Anemia, thrombocytopenia and normal or decreased leukocyte count, mainly due to lymphopenia were the main hematological features observed in seropositive sheep. The presence of these features raises the suspicion of Borrelia infection in tick infested sheep. The seropositivity of 23.58% in sheep raises concerns of Borrelia circulation, especially in rural areas and potential risk of transmission to humans.

Background:Interstitial lung disease (ILD) is a severe extra-articular manifestation of rheumatoid arthritis (RA). However, the effect of RA disease activity on the course of ILD is not yet known.Objectives:To assess the natural course of lung physiology of RA-ILD and the relation between arthritis activity and pulmonary physiology in patients with RA-ILD.Methods:The Korean Rheumatoid Arthritis ILd (KORAIL) cohort is the prospective observational cohort and aims to investigate the natural course of RAILD. Based on either 1987 or 2020 ACR criteria, patients diagnosed with RA and ILD based on CT scan were recruited from six tertiary medical hospitals in Korea since January 2015. RA disease activity was assessed using disease activity (DAS)28-ESR and CRP, annually. Pulmonary function tests (PFT), including FVC and DLCO were conducted annually. According to the transition of DAS28-ESR status, we classified patients into four groups: Group A. persistent remission or low disease activity, Group B. improvement, Group C. worsening, Group D. persistent moderate to high disease activity.Results:We analyzed 143 patients who completed a 2-year follow-up (visit 2) or had died with available PFT results at least twice. Mean duration since RA diagnosis and since ILD diagnosis was 7.6±8.0 and 2.7±3.1 years, respectively. Twenty-four patients were Group A, 33 Group B, 10 Group C and 30 Group D. The mean of FVC (mL) and % of the predicted value in FVC was significantly lower in Group D than in other groups (Table 1). The annual rate of decline in FVC was -42 (95% CI -93~10) mL·year-1 in Group B while -113 (95% CI -206~-21) mL·year-1 in Group C (Figure 1A). The annual decline rate in Group C was further exaggerated in patients with ≥ 80% of FVC predicted (-141, 95% CI -251~-32 mL·year-1). During two years of follow-up, patients ever experienced a relative decline of ≥10% from the enrollment in FVC predicted was 27.3%(n-9/33) in Group B whereas 30.0% (3/10) in Group C. The annual rate of decline in % of DLco predicted value was also the largest in Group C (-4.6 %·year-1, 95%CI -8.5~-0.7), which further exaggerated in patients with ≥ 80% of FVC predicted (-4.9%·year-1, 95 %CI -8.3~-1.5, Figure 1B). Of note, about half of patients with maintained not only low disease activity (Group A) but also moderate to severe disease activity (Group D) improved in DLco at least 10% or more from the enrollment of DLco predicted value (Group A: 54.2%, n=13/24, Group D: 46.7%, n=14/30).Conclusion:RA disease activity is associated with the change of lung physiology in patients with RA-ILD; worsening disease activity associated with a further decrease of annual change in FVC and maintaining low disease activity associated with a further increase of annual change in % of DLco predicted value.Table 1.The analysis of forced vital capacity (FVC) according to disease activity transition group.Group AGroup BGroup CGroup DFVC (mL), mean±SD2810.0±771.12528.8±735.32801.0±952.72048.3±575.7FVC % of predicted, mean±SD87.5±14.586.5±16.693.0±15.677.2±17.3Rate of FVC decline, mL·year-1 (95% CI)-52 (-112,7)-42 (-93,10)-113 (-206, -21)1 (-52, 54)A 10-point decline from V1 in predicted FVC value, n (%)29 (20.3)6 (25.0)6 (18.2)3 (30.0)Relative decline of 10% from the enrollment in predicted FVC value, n (%)35 (24.5)5 (20.8)9 (27.3)3 (30.0)Figure 1.The annual change of pulmonary physiology according to disease activity transition group.Acknowledgements:This work was supported by the Korea Health Technology R&D Project through the Korea Health Industry Development Institute, funded by the Ministry of Health and Welfare, Republic of Korea (grant no.HI14C1277).Disclosure of Interests:None declared
