Study of Gut Microbiota Diversity in Children Aged 1-3 Years on Prolonged Antibiotic Prophylaxis for Grade 3 or Higher Vesicoureteral Reflux Compared With 2 Age-matched Control Groups
Urinary tract infections are very common in pediatrics. Urinary antibiotic prophylaxis is commonly used in children with malformative uropathies. Long-term, low-dose antibiotic prophylaxis with trimethoprim-sulfamethoxazole has been associated with a decrease in the number of urinary tract infections in susceptible children, but not systematically with a decrease in the risk of renal scarring (depending of uropathy stage). Long-term antibiotic prophylaxis has implications for the acquisition of antibiotic resistance. A child receiving antibiotic prophylaxis for urinary tract infection is around 6 times more likely to develop a multidrug-resistant infection. In the general population, the microbiota of children treated with curative antibiotics is less diverse in terms of species and strains. In addition, short-term compositional changes are observed between consecutive samples of children treated with antibiotics. The gut microbiota modulates the immune system, in particular via metabolites (SCFA, polysaccharide A) produced by bacteria that modify the expansion and function of regulatory T-cells. The disturbances of the intestinal microbiota play a role in the medium and long term on the acquisition of pathologies, such as atopy. The study authors wish to describe the intestinal microbiota of children with vesico-ureteral reflux treated long-term with trimethoprim-sulfamethoxazole and compared it those not receiving antibiotic prophylaxis and to healthy children.

Postoperative Upper Limb Edema and Dysfunction Generated by Axillary Nodes Excision Differs Due to the Ratio of Axillary Lymphatic and Axillary Vein Reflux in Breast Cancer Patients: a Prospective Cohort Study
The purpose of this study is to compare the difference in the incidence of upper limb edema and dysfunction between the Preponderant lymphatic reflux group (high ratio of axillary lymphatic reflux to axillary vein reflux) and the Preponderant venous reflux group (low ratio of axillary lymphatic reflux to axillary vein reflux).

Ablation of Esophageal Inlet Patches in Patients Referred for pH-Testing Due to Possible Extra-Esophageal Symptoms of Gastro-Esophageal Reflux Disease
Patients with suspected extra-esophageal manifestations of gastro-esophageal reflux disease (GERD), such as cough, hoarseness, and globus, are often referred for pH testing. However, many of these symptoms may actually be due to an esophageal inlet patch. We aim to evaluate patients referred for pH testing to see if they have an inlet patch, to perform ablation of the inlet patch if detected, and then compare the outcomes of patients with an inlet patch who underwent ablation versus those without an inlet patch.

Analysis of Incidence and Risk Factors Associated With Gastroesophageal Reflux Disease and Esophagitis After Peroral Endoscopic Myotomy
Achalasia is an uncommon disorder that results from the degeneration of ganglion cells of the myenteric plexus in the lower esophageal wall. Peroral endoscopic myotomy (POEM) is a minimally invasive procedure capable of overcoming limitations of achalasia treatments. This study aimed to: 1) identify the prevalence of reflux esophagitis and asymptomatic GERD in patients who underwent POEM, and 2) evaluate patient and intraprocedural variables associated with post-POEM GERD.

To Investigate the Incidence of Reflux in Patients After Per-oral Endoscopic Myotomy in Achalasia Cardia Patients
Achalasia is a rare motility disorder of the oesophagus that is characterized by aperistalsis of the oesophagal body and dysrelaxation of the lower oesophagal sphincter (LES). Current treatment is palliative, and the aim of the treatment is to diminish the obstructive function of the esophagogastric junction (EGJ). Due to this approach, the most frequent complication post-treatment is gastroesophageal reflux (GER). However, not every treated patient develops GER symptoms and the mechanism behind the occurrence of GER in treated achalasia are unclear. In this study, we aim to Investigate the incidence of reflux in patients after peroral endoscopic myotomy in patients with achalasia cardia.

Comparison and Evaluation of USSQ (Ureteral Stent Symptom Questionnaire）, OABSS (Overactive Bladder Symptom Score), and the Drainage/Anti-reflux Effect Between Three Kinds of Ureteral D-J（Double-J) Stents in Patients Who Underwent URL (Ureteroscopic Holmium Laser Lithotripsy）
Indwelling double-J ureteral stent (D-J stent) are routinely placed in patients who received ureteroscopic lithotripsy (URL) in Xinhua Hospital Urology Department. At present, three types of D-J stents, namely Cook/Kang Yi Bo(KYB)/Urovisionare are used, and usually removed in the day ward four weeks after surgery. This study intends to randomly divide patients with urolithiasis based on the preoperative OABSS (overactive bladder symptom score) questionnaire into three groups, namely Cook D-J stent group, KYB anti-reflux D-J stent group, Urovision trigonal D-J stent group, with corresponding D-J stent indwelled for 4 weeks respectively. The patient's USSQ ureteral stent symptom questionnaire）scale and OABSS scale were collected at 1 week, 4 weeks (before the removal of D-J stents), and 5 weeks (1 week after removal of D-J stents) after URL operation, and the D-J stents removed from the patients were collected, and their drainage and anti-reflux effects were measured in vitro.
