ABSTRACT
@#Antihistamine is standard chronic spontaneous urticaria (CSU) therapy. Weight gain is a side effect of concern as prolonged high dose therapy is common. We investigated the effects of 12-weeks loratadine therapy on weight, appetite and parameters of metabolic syndrome (MetS). A cohort study was performed involving CSU patients aged ≥18 years. Patients with diseases or on drugs affecting weight or appetite were excluded. CSU was treated according to standard management. Weight, height, waist circumference (WC), body mass index (BMI) and blood pressure (BP), Urticaria Activity Score 7 (UAS7), Dermatology Life Quality Index (DLQI), hunger and satiety questionnaire, fasting blood sugar (FBS) and fasting lipid profile (FLP) were obtained at baseline, week 6 and week 12. Loratadine cumulative dose were determined. Thirteen (33.33 %) males and 26 (66.67 %) females aged 33.00 (12.00) years participated. Median weight was 62.55 (18.30) kg, BMI 24.60 (6.80) kg/m2, 13(33.33%) patients had normal weight, 12 (30.77%) overweight, 11 (28.21%) obese and 3 (7.69%) underweight. Significant weight gain was observed at week 6, 67.56 ± 16.14 kg vs 68.16 ± 16.95 kg, p < 0.05 and 67.56 ± 16.14 kg vs 64.73 ± 14.60 kg, p = 0.04 at week 12. Changes in BMI, WC, BP, FBS and FLP were insignificant. Three patients developed MetS. Hunger and satiety scores were unaffected. Loratadine induced weight gain despite no effects on appetite. Weight should be monitored in patients on long term loratadine therapy.
ABSTRACT
Objective:To analyze the unqualified rate of the observation indicaors before and after the implementation of “Sunshine Kitchen Project” in order to provide reference for improving the management of catering industry. Methods:This study included 415 catering establishments with implementation of the “Sunshine Kitchen Project” as intervention group and 210 catering establishments as control group without the implementation. By combining cohort study with case-control study, the unqualified rate of each observation indicator in intervention group and control group was analyzed. Results:After the intervention of “Sunshine Kitchen Project”, the unqualified rate of seven observation indicators related to operational behavior was significantly reduced, with an overall decrease of 12.44%. There were significant differences among the unqualified rate of large and medium-sized catering units and canteens in the intervention group (P < 0.001). There was no statistically significant change in the unqualified rate of seven indicators in the control group (P > 0.1). Compared with the control group before and after the intervention, the reduction of unqualified rate in the intervention group was significantly larger than that in the control group. The overall unqualified rate of the intervention group was significantly lower than that of the control group (P < 0.001). Conclusion:The project of “Sunshine Kitchen” plays an active role in promoting the standardized operation of catering industry.
ABSTRACT
@#Objective To study the clinical results of Mini Maze procedure in atrial fibrillation patients with impaired left ventricular systolic function. Methods From June 2010 to December 2017, 86 atrial fibrillation patients with impaired left ventricular systolic function received Mini Maze procedure including 54 males and 32 females, with an average age of 60.7±5.9 years. Among them, 12 were with paroxysmal, 27 were with persistent and 47 were with long-standing persistent atrial fibrillation. The mean atrial fibrillation duration was 6.5±4.8 years. CHA2DS2-VASc score was 2.2±1.1. The mean diameter of left atrium was 46.9±3.8 mm. The mean diameter of left ventricle was 51.7±4.6 mm. The preoperative ejection fraction was 42.2%±4.7%. All patients received Mini Maze procedure after general anesthesia. The ablation included 3 annular ablations and 3 linear ablations. The left atrial appendage was excised by Endo-Gia. Ablation of Marshall ligament and epicardial autonomic ganglions were made by an ablation pen. Results Eighty-six patients successfully completed the procedure without transition to thoracotomy. There was no death during the perioperative period. Seventy-seven patients (89.5%) maintained sinus rhythm at discharge. Eighty patients were followed up for 27.2±12.1 months and 72 patients maintained sinus rhythm. The overall postoperative left ventricular ejection fraction was 47.1%±6.2%. The ejection fraction of the postoperative sinus rhythm group was 48.2%±5.8%, and the ejection fraction of the non-sinus group was 41.6%±5.8% (P<0.05). Multivariate regression analysis showed a left atrial diameter (HR=1.485, 95%CI 1.157-1.906, P<0.05) and an increase in ejection fraction over 10% (HR=18.800, 95%CI 1.674-189.289, P<0.05) were closely related to postoperative recurrence. Kaplan-Meier curve analysis showed that the recurrence rate of atrial fibrillation was significantly lower in patients with an increase in postoperative ejection fraction over 10% (P<0.05). Conclusion Mini Maze procedure is safe and effective in the treatment of atrial fibrillation patients with left ventricular systolic dysfunction, which helps to improve left ventricular function to prevent the vicious circle of atrial fibrillation and heart failure.
ABSTRACT
@#Objective To summarize the application and clinical effect of left anterior minimally invasive thoracotomy to surgical repair of subarterial ventricular septal defect (VSD) in children. Methods From October 2015 to April 2019, 21 children with subarterial VSD underwent surgical repair via left anterior minimally invasive thoracotomy. There were 13 males and 8 females, aged 5-13 (9.1±2.2) years, and weighing 22-55 (35.6±9.5) kg. The diameter of subarterial VSD was 4-15 (9.1±3.3) mm. Eight patients had right coronary valve prolapse, and 4 aortic valve regurgitation (3 mild and 1 mild-to-moderate). The minimally invasive surgery was performed via left parasternal thoracotomy through the second or third intercostal space. The peripheral perfusion was performed with femoral arterial and venous cannulation. After aortic cross-clamp (ACC), subarterial VSD was performed with direct suture of patch closure through an incision on the root of pulmonary artery. Results All patients successfully underwent surgical repair (patch closure, n=15; direct suture, n=6) of subarterial VSD through left anterior minimally invasive thoracotomy. The cardiopulmonary bypass time was 45-68 (57.1±6.3) min. The ACC time was 23-40 (32.6±4.7) min. The postoperative ventilation time was 5-9 (6.3±1.3) h, postoperative in-hospital time was 5-8 (5.7±1.0) d and drainage volume was 33-105 (57.5±17.7) mL in postoperative 24 h. No death, residual VSD shunt, atrioventricular block, wound infection or thoracic deformity occurred during the perioperation or follow-up. Only one patient still had trivial aortic valve regurgitation. Conclusion Left anterior minimally invasive thoracotomy could be safely and effectively applied to surgical repair of subarterial VSD in children, with satisfactory early- and mid-term outcomes.
ABSTRACT
Objective@#To investigate the current status of screen time in preschoolers during the outbreak of Corona Virus Disease 2019 (COVID-19), and the influences of parent-child active play and school online education on screen time.@*Methods@#A total of 2 370 preschoolers were chosen through clustering sampling from 7 kindergartens in Wuxi urban areas. Questionnaire survey was administered to parents for child screen time, active play, online education as well as characteristics information.@*Results@#A total of 1 428(60.3%) preschoolers reported more than 1 hour screen time a day, and 1 915(80.8%) preschoolers reported more than 20 minutes consecutive screen time. Compared with the weekend before the COVID-19 outbreak, 1 551(65.4%) preschoolers reported an increase of 10 minutes in screen time perday, and 1 444(60.9%) reported an increase of 5 minutes for one sersion. Logistic regression analysis showed that after controlling for confounding factors, high frequency of parent-child active play, parents’ exercise habits, online education from kindergartens and children’s active participation in the online education were negatively associated with preschoolers’ excessive and increased screen time during this period(OR=0.39-0.79, P<0.05).@*Conclusion@#During the COVID-19 outbreak, preschoolers’ media use in Wuxi city is worrisome. Parent-child active play, parents’ exercise and online education from kindergartens may play a positive role in reducing preschoolers’ media use.
ABSTRACT
@#Objective To determine the effects of resecting the lower half of left stellate ganglion (LSG) on fast ventricular rate (VR) in persistent atrial fibrillation (AF) and its mechanism. Methods Twelve mature healthy male beagle dogs (15–25 kg) were studied. They were randomly divided into two groups (an experimental group and a control group, 6 dogs in each group). The control group were merely performed with rapid left atrial pacing to induce persistent AF. The experimental group were disposed with rapid left atrial pacing and received resection of the lower half of LSG after the persistent AF was documented. Simultaneously the ventricular rates were monitored separately before anesthesia, after anesthesia, 30 minutes and one month after LSG resection. The forward passing effective refractory period (ERP) of the canine atrioventricular node (AVN) was also measured. Results Each dog was documented with persistent AF after 3–6 weeks’ left atrial pacing. After resecting the lower half of LSG for 30 minutes (the control group was only observed for 30 minutes without LSG resection), the average VR of the control group attained 144.5±4.2 beats/min, while that of the experimental group was 121.5±8.7 beats/min (P<0.001). After resecting the lower half of LSG for one month (the control group was observed for one month without LSG resection), the average VR of the control group was 139.2±5.6 beats/min, while that of the experimental group was 106.5±4.9 beats/min (P<0.001). Meantime, the forward passing ERP of AVN of the experimental group was significantly prolonged than that of the control group (265.6±7.8 msvs.251.1±4.6 ms, P=0.003). Conclusion Resection of the lower half of LSG is efficient in reducing VR in canines with persistent AF, one of the mechanisms of which may be prolonging the forward passing ERP of AVN.
ABSTRACT
ABSTRACT Objective: To determine whether serum levels of anti-acetylcholine receptor antibody (anti-AChR-Abs) are related to clinical parameters of blepharospasm (BSP). Methods: Eighty-three adults with BSP, 60 outpatients with hemifacial spasm (HFS) and 58 controls were recruited. Personal history, demographic factors, response to botulinum toxin type A (BoNT-A) and other neurological conditions were recorded. Anti-AChR-Abs levels were quantified using an enzyme-linked immunosorbent assay. Results: The anti-AChR Abs levels were 0.237 ± 0.022 optical density units in the BSP group, which was significantly different from the HFS group (0.160 ± 0.064) and control group (0.126 ± 0.038). The anti-AChR Abs level was correlated with age and the duration of response to the BoNT-A injection. Conclusion: Patients with BSP had an elevated anti-AChR Abs titer, which suggests that dysimmunity plays a role in the onset of BSP. An increased anti-AChR Abs titer may be a predictor for poor response to BoNT-A in BSP.
RESUMO Objetivo: Determinar se os níveis séricos do anticorpo antirreceptor de acetilcolina (anti-AChR-Abs) estão relacionados aos parâmetros clínicos do blefaroespasmo (BSP). Métodos: Fora recrutados 83 adultos com BSP, 60 pacientes ambulatoriais com espasmo hemifacial (HFS) e 58 controles. Foi aplicado um questionário para registrar história pessoal, fatores demográficos, resposta à toxina botulínica tipo A (BoNT-A) e outras condições neurológicas. Os níveis de anti-AChR-Abs foram quantificados usando um ensaio imunoenzimático. Resultados: O nível de anti-AChR-Abs foi de 0,237 ± 0,022 unidades de densidade óptica (OD) no grupo BSP, significativamente diferente em comparação com o grupo HFS (0,160 ± 0,064) e o grupo controle (0,126 ± 0,038). O nível de anti-AChR-Abs se correlacionou com a idade e a duração da resposta à injeção de BoNT-A. Conclusão: Pacientes com BSP apresentaram títulos elevados de anti-AChR-Abs, o que sugere que a desimunidade desempenha um papel no surgimento de BSP. O aumento do título de anti-AChR-Abs pode ser um preditor de resposta insuficiente à BoNT-A em BSP.

Abstract Background: The influence of pulmonary vein (PV) anatomy on cryo kinetics during cryoballoon (CB) ablation is unclear. Objective: To investigate the relationship between PV anatomy and cryo kinetics during CB ablation for atrial fibrillation (AF). Methods: Sixty consecutive patients were enrolled. PV anatomy, including ostial diameters (long, short and corrected), ratio between short and long diameters, ostium shape (round, oval, triangular, and narrow), and drainage pattern (typical, with common trunk, common antrum, ostial branch and supernumerary PV) were evaluated on multi-detector computed tomography (MDCT) images pre-procedure. Cryo kinetics parameters [balloon freeze time from 0 to -30ºC (BFT), balloon nadir temperature (BNT) and balloon warming time from -30 to +15ºC (BWT)] were recorded during procedure. All p values are two-sided, with values of p < 0.05 considered to be statistically significant. Results: 606 times of freezing cycle were accomplished. Moderate negative correlation was documented between BNT and corrected PV diameter (r = -0.51, p < 0.001) when using 23-mm CBs, and mild negative correlation (r = - 0.32, p = 0.001) was found when using 28-mm CBs. Multivariate logistic regression analysis revealed that PV corrected ostial diameter (OR, 1.4; p = 0.004) predicted a BNT < -51ºC when using 23-mm CBs, while PV ostium oval shape (OR, 0.3; p = 0.033) and PV locations (left inferior PV: OR, 0.04; p = 0.005; right superior PV: OR, 4.3; p = 0.025) predicted BNT < -51ºC when using 28-mm CBs. Conclusions: MDCT can provide PV anatomy accurate evaluation prior CB ablation. PV anatomy is associated with cryo kinetics during ablation.
Resumo Fundamentos: A influência da anatomia da veia pulmonar (VP) na criocinética durante a ablação por criobalão (CB) não está clara. Objetivo: Investigar a relação entre a anatomia da VP e a criocinética durante a ablação com CB para fibrilação atrial (FA). Métodos: sessenta pacientes consecutivos foram matriculados. Foram avaliados em imagens de tomografia computadorizada multidetectora (TCMD) pré-procedimento a anatomia da VP, incluindo diâmetros dos óstios (longo, curto e corrigido), relação entre diâmetros curtos e longos, forma do óstio (redondo, oval, triangular e estreito) e padrão de drenagem (típico, com tronco comum, antro comum, ramo ostial e VP supranumerária). Os parâmetros criocinéticos [tempo de congelamento de balão de 0 a -30ºC (TCB), temperatura do nadir do balão (TNB) e tempo de aquecimento do balão de -30 a + 15ºC (TAB)] foram registrados durante o procedimento. Todos os valores de p são bicaudais, com valores de p < 0,05 considerados estatisticamente significativos. Resultados: o ciclo de congelamento foi realizado 606 vezes. Correlação negativa moderada foi documentada entre o TNB e o diâmetro VP corrigido (r = - 0,51, p < 0,001) ao usar CBs de 23 mm e correlação negativa leve (r = - 0,32, p = 0,001) foi encontrada ao usar 28- mm CBs. A análise de regressão logística multivariada revelou que o diâmetro corrigido do óstio da VP (OR, 1,4; p = 0,004) previu um TNB < -51ºC ao usar CB de 23 mm, enquanto a forma oval do óstio VP (OR, 0,3; p = 0,033) e as localizações da VP (VP inferior: OR, 0,04; p = 0,005; VP superior direito: OR, 4,3; p = 0,025) previram TNB < -51ºC ao usar CBs de 28 mm. Conclusões: A TCMD pode fornecer uma avaliação precisa da anatomia da VP antes da ablação por CB. A anatomia da VP está associada à criocinética durante a ablação.

@#Objective To investigate the changes of hemodynamics in patients weaning intra-aortic balloon pump (IABP) by using progressive volume deflation followed by rate reduction. Methods We retrospectively analyzed the clinical data of 36 patients aged 68.9±4.7 years, 22 males and 14 females, who underwent progressive volume deflation followed by rate reduction for IABP weaning in Xinhua Hospital between September 2006 and January 2016. Progressive volume deflation followed by rate reduction was used to wean IABP and collect hemodynamics parameters of each time point. Results All the patients successfully weaned IABP. One patient got re-IABP assistant 36 hours after the first successful weaning. One early death and three patients (8%) with postoperative IABP-related complications were embolization of the toe artery. One was in ipsilateral limb, and two of contralateral limb. One patient with acute hepatic insufficiency and one patient with acute renal insufficiency cured after treatment. Conclusion Intra-aortic balloon pump weaning is successful by using volume deflation followed by rate reduction which allowed better hemodynamic parameters.
ABSTRACT
@#Objective To explore the technique of performing minimally invasive Cox Maze Ⅳ procedure by bipolar clamp through right lateral minithoracotomy for atrial septal defect (ASD) combined with atrial fibrillation (AF) in adults. Methods Thirty-five patients (21 males, 14 females with age ranging from 45 to 73 years) with ASD and persistent or long-standing persistent AF received minimally invasive Cox Maze Ⅳ procedure and ASD closure from August 2012 to April 2016 at Department of Cardiothoracic Surgery, Xinhua Hospital. Diameter of left atrium ranged from 39 to 60 mm and left ventricle ejection fraction (LVEF) ranged from 48% to 62%. Diameter of ASD ranged from 20 to 35 mm. Cox-maze Ⅳ procedure was performed through right minithoracotomy entirely by bipolar radiofrequency clamp. Then, mitral or tricuspid valvuloplasty and surgical ASD closure was performed through right minithoracotomy. Results All patients successfully underwent this minimally invasive surgery. No patient needed conversion to sternotomy. The mean cardiopulmonary bypass time was 120.1±14.1 min. The mean aortic cross-clamp time was 79.5±12.2 min. There was no early death or pacemaker implantation perioperatively. The average length of hospital stay was 10.1±2.7 d. At a mean follow-up of 22.8±12.2 months, sinus rhythm was restored in 32 patients (32/35, 91.4%). Cumulative maintenance of normal sinus rhythm without AF recurrence at 2 years postoperatively was 89.1%±6.0%. Conclusion The minimally invasive Cox Maze Ⅳprocedure performed by bipolar clamp through right minithoracotomy is safe, feasible, and effective for adult patients with ASD combined with AF.
ABSTRACT
@#Objective To analyze the mid-term results of surgical treatment for prosthetic valve endocarditis (PVE). Methods We retrospectively analyzed the clinical data of 22 PVE patients operated in our institution from January 2006 to June 2016. There were 14 males and 8 females, aged 31-62 (49.6±11.8) years. PVE occurred following single valve replacements in 20 patients, including aortic valve replacements in 12 and mitral valve replacements in 8. Two patients suffered PVE after multi-valve replacement, which was aortic and mitral valves. Mechanical valves were used in all patients. Early PVE (<1 year after valve implantation) was detected in 10 patients, and late PVE (>1 year after valve implantation) in 12 patients. Blood culture was negative in 6 patients. Fifteen patients underwent emergent or urgent surgery (within one week after definite diagnosis) and 7 elective surgery. Paravalvular abscess was detected in 12 patients and repaired bovine pericardium. Results Three patients (13.6%) died postoperatively in hospital, among whom two died of multiple systemic organ failure, and the other died of cerebral hemorrhage. Main postoperative complications included low cardiac output syndrome in 5 patients (22.7%), renal dysfunction in 6 (27.3%), respiratory failure in 5 (22.7%) and pulmonary infection in 4 (18.2%). During the follow-up of 6-120 (53.6±20.8) months, 2 deaths were observed in the middle term, including one sudden death and the other of cerebral infarction. No recurrent infection or valve-related surgery was observed during the follow-up. The survival rate was 86.4% in 1 year and 70.4% in 5 years. Conclusion PVE is a very severe disease with high mortality. Early surgical treatment and complete removal of infectious tissues have preferable early- and mid-term results.
