ABSTRACT
INTRODUCTION: Inadequate bowel preparation (IBP) prior to colonoscopy remains a common problem. This meta-analysis aimed to assess the risk factors associated with IBP. METHODS: We searched multiple databases for studies that assessed risk factors for IBP after adjustment and reported the data as adjusted odds ratios (OR) with 95% confidence intervals. Meta-analyses were conducted using a random-effects model, and pooled adjusted ORs for risk factors reported in ≥3 studies were constructed. RESULTS: 154 studies with 258,257 participants were included. We analyzed 48 unique risk factors. Sociodemographic predictors of IBP were Medicaid insurance, obesity, current tobacco use, age≥65, Black race, low education level, male gender, and unmarried status. Comorbidity-related predictors of IBP were any psychiatric disease, cirrhosis, ASA class≥3, poor functional status, constipation, diabetes, prior abdominopelvic surgery, and hematochezia. Medication-related predictors of IBP were tricyclic antidepressants (TCA), antidepressants, opioid, non-TCA antidepressants, and calcium channel blockers. Preparation/procedure-related predictors of IBP were brown liquid rectal effluent, any incomplete bowel preparation (BP) intake, lack of split-dose BP, increased BP-to-defecation interval, any non-adherence to dietary instructions, increased BP-to-colonoscopy interval, any BP intolerance, prior IBP, and inpatient status. While afternoon colonoscopy was a predictor of IBP, subgroup analysis of prospective studies revealed no significant association. CONCLUSIONS: Our meta-analysis focused on adjusted risk factors to provide precise estimates of the most important risk factors for IBP. Our findings could help develop a validated prediction model to identify high-risk patients for IBP, improve colonoscopy outcomes, reduce the need for repeat colonoscopies, and reduce associated healthcare costs.
ABSTRACT
Gastroparesis is a common complaint among patients with diabetes. Symptoms tend to improve following successful pancreas transplantation (PTx), but persist despite euglycemia in a subset of patients. We aimed to assess the benefit of gastric peroral endoscopic myotomy (G-POEM) in persistent gastroparesis following PTx. This was a single center retrospective review of all patients who underwent G-POEM for persistent gastroparesis following PTx. Patient demographics, pre and post procedure perception of symptom severity according to the patient assessment of upper gastrointestinal symptoms severity index (PAGI-SYM), gastroparesis cardinal symptom index (GCSI) score, and 36-item short form survey (SF36) score along with gastric emptying scintigraphy (GES) were analyzed. Seven PTx recipients underwent G-POEM for persistent gastroparesis symptoms. The majority were female. All reported nausea/vomiting, abdominal pain, bloating, and post prandial fullness prior to G-POEM. The post procedure survey scores improved in all patients although this was not significant. The improvement in gastric emptying on GES was statistically significant. G-POEM is a relatively new treatment option for gastroparesis. While it requires specialized proceduralist and training, we have documented improvement in the management of symptoms. With increasing experience, we anticipate more significant benefit in post PTx patients with persistent symptoms of gastroparesis undergoing G-POEM.

BACKGROUND AND AIMS: Positive vertical margins (VMs) are common after endoscopic submucosal dissection (ESD) of T1b esophageal cancer (EC) and are associated with an increased risk of recurrence. Traction during ESD provides better exposure of the submucosa and may allow deeper dissection, potentially reducing the risk of positive VMs. We conducted a retrospective multicenter study to compare the proportion of resections with positive VMs in ESD performed with versus without traction in pathologically staged T1b EC. METHODS: Patients who underwent ESD revealing T1b EC (squamous or adenocarcinoma) at 10 academic tertiary referral centers in the United States (n = 9) and Brazil (n = 1) were included. Demographic and clinical data were abstracted. ESD using either traction techniques (tunneling, pocket) or traction devices (clip line, traction wire) were classified as ESD with traction (Tr-ESD) and those without were classified as conventional ESD without traction. The primary outcome was a negative VM. Multivariable logistic regression was used to assess associations with negative VMs. RESULTS: A total of 166 patients with pathologically staged T1b EC underwent Tr-ESD (n = 63; 38%) or conventional ESD without traction (n = 103; 62%). Baseline factors were comparable between both groups. On multivariable analysis, Tr-ESD was found to be independently associated with negative VMs (odds ratio, 2.25; 95% confidence interval, 1.06-4.91; P = .037) and R0 resection (odds ratio, 2.83; 95% confidence interval, 1.33-6.23; P = .008). CONCLUSION: Tr-ESD seems to be associated with higher odds of negative VMs than ESD without traction for pathologically staged T1b EC, and future well-conducted prospective studies are warranted to establish the findings of the current study.
ABSTRACT
Oxidative stress (OS), defined as an overabundance of reactive oxygen species (ROS) or a deficiency of antioxidants, has been linked to sperm damage and male infertility. There are many sources of OS and inflammation including varicocele, tobacco usage, alcohol, obesity/metabolic syndrome, leukocytospermia, sexually transmitted disease (i.e., Neisseria gonorrhoeae, Chlamydia trachomatis, Treponema pallidum), bacterial prostatitis, microorganism mutations leading to more OS, and viral infections (i.e., human immunodeficiency virus, hepatitis). This review is focusing on infection and inflammation-mediated OS, the inflammatory markers underlying pathology, clinical significance in male infertility, and a brief description of the recommended treatment modalities.

PURPOSE: We evaluate outcome of in-home diagnostic ambulatory video-EEG monitoring (AVEM) performed on a nationwide cohort of patients over one calendar year, and we compare our findings with outcomes of inpatient adult and pediatric VEM performed during the same year at two academic epilepsy centers. METHODS: This is a retrospective cohort study. We obtained AVEM outcome data from an independent ambulatory-EEG testing facility. Inpatient VEM data from a 4-bed adult epilepsy center and an 8-bed pediatric epilepsy center were also included. Primary outcome measure was composite percentage of VEM records with epileptiform activity on EEG tracings or at least one video-recorded pushbutton event. We assessed patient-reported symptoms documented in AVEM event diaries. RESULTS: Of 9221 AVEM recordings performed across 28 states, 62.5% attained primary outcome. At least one patient-activated pushbutton event was captured on video in 54% of AVEM recordings (53.6% in adults, 56.1% in children). Epileptiform activity was reported in 1657 (18.0%) AVEM recordings (1473 [88.9%] only interictal, 9 [0.5%] only ictal, 175 [10.6%] both interictal and ictal). Most common patient-reported symptomatology during AVEM pushbutton events was behavioral/autonomic/emotional in adults and children. Compared to AVEM, inpatient VEM captured more confirmed representative events in adult and pediatric samples. CONCLUSIONS: AVEM is useful for non-urgent diagnostic evaluation of events.
