Article Synopsis
  • Bovine babesiosis, caused by Babesia bovis and Babesia bigemina, significantly impacts livestock and is often treated with imidocarb in areas lacking vaccines.
  • The study involved 15 heifers, with 12 receiving imidocarb and all exposed to ticks to evaluate the development of humoral immunity through seroconversion.
  • Results showed that after multiple treatments, a majority of the treated heifers did develop antibodies against the parasites, but not all animals seroconverted, highlighting potential limitations in the effectiveness of the chemoprophylaxis approach.

Article Synopsis
  • Gastrointestinal angiodysplasias are vascular abnormalities that can cause severe anemia requiring frequent blood transfusions, and octreotide has been suggested to help reduce rebleeding rates in patients.
  • A multicenter, randomized controlled trial compared the effectiveness of octreotide (40 mg every 28 days) to standard care in reducing transfusion requirements over one year for patients with this condition.
  • Results showed that patients treated with octreotide required significantly fewer transfusion units (11.0) compared to those receiving standard care (21.2), indicating that octreotide effectively reduces the need for transfusions in these patients.

For non-dysplastic Barrett's Esophagus (BE) patients, guidelines recommend endoscopic surveillance every 3 to 5 years with four-quadrant random biopsies every 2 cm of BE length. Adherence to these guidelines is low in clinical practice. Pooling BE surveillance endoscopies on dedicated endoscopy lists performed by dedicated endoscopists could possibly enhance guideline adherence, detection of visible lesions, and dysplasia detection rates (DDRs).

Introduction: Endoscopic ultrasonography guided tissue acquisition (EUS + TA) is used to provide a tissue diagnosis in patients with suspected pancreatic cancer. Key performance indicators (KPI) for these procedures are rate of adequate sample (RAS) and sensitivity for malignancy (SFM).

Aim: assess practice variation regarding KPI of EUS + TA prior to resection of pancreatic carcinoma in the Netherlands.

Background: Health-related Quality of life (HRQoL) in patients with Barrett's esophagus (BE), a premalignant condition, may be influenced by gastroesophageal reflux disease (GERD) symptoms and the risk of developing esophageal adenocarcinoma.

Methods: We aim to investigate HRQoL in non-dysplastic Barrett Esophagus (NDBE) patients, identify factors associated with a negative illness perception of the diagnosis BE and compare outcomes between patients treated in a specialized BE center with non-expert centers. In this multi-center cross-sectional study, HRQoL of NDBE patients were assessed using the Short Form 36, Hospital Anxiety and Depression Scale, Cancer worry Scale, and Reflux Disease Questionnaire.

There has been particular interest in the deployment of digital pathology (DP) and artificial intelligence (AI) in the diagnosis of prostate cancer, but little is known about the views of the public on their use. Prostate Cancer UK supporters were invited to an online survey which included quantitative and qualitative questions exploring views on the use of DP and AI in histopathological assessment. A total of 1276 responses to the survey were analysed (response rate 12.

Two cases are described of patients who present with severe malnutrition more than five years after undergoing a Roux-en-Y gastric bypass and who have deficiencies of both micronutrients (vitamins and minerals) and macronutrients (proteins). This problem appears to be caused by both iatrogenic malabsorption after gastric bypass as well as dysphagia due to a local anastomotic complication (stenosis and marginal ulcer). Although both the severity of the deficiencies and the timing are exceptional, we want to emphasize the importance of lifelong supplement use and follow-up after bariatric surgery.

Importance: Diagnostic yield of upper gastrointestinal (GI) tract endoscopy for uninvestigated dyspepsia is low, and its clinical implications are limited. There is an unmet need for better strategies to reduce the volume of upper GI tract endoscopic procedures for dyspepsia.

Objective: To study the effectiveness of a web-based educational intervention as a tool to reduce upper GI tract endoscopy in uninvestigated dyspepsia.

Objective: To evaluate the five-year clinical performance of Scotchbond Universal Adhesive (SU; 3M Oral Care, St. Paul, MN, USA) in non-carious cervical lesions (NCCLs) using two evaluation criteria.

Methods: Thirty-nine patients participated in this study.

The Dutch guidelines for esophageal and gastro-esophageal junction (GEJ) cancer recommend discussion of patients by a multidisciplinary tumor board (MDT). Despite this recommendation, one previous study in the Netherlands suggested that therapeutic guidance was missing for palliative care of patients with esophageal cancer. The aim of the current study was therefore to assess the impact of an MDT discussion on initial palliative treatment and outcome of patients with esophageal or GEJ cancer.

Claw deformity of the foot is frequently seen in patients with diabetes mellitus. Percutaneous flexor tenotomy is a simple surgical procedure for the treatment of foot ulcers on the distal end of the toe caused by this deformity. This procedure can also be performed to prevent ulcers in claw toes that are at risk of ulceration.

Bile cast nephropathy is an often overlooked condition of acute renal injury in the setting of high serum bilirubin. While the exact pathophysiology remains unknown, possible mechanisms of renal injury are tubular obstruction from bile casts, direct toxicity from bile acids, and decreased renal perfusion due to hemodynamic changes. We present a patient with hyperbilirubinemia as a result of common bile duct obstruction due to pancreatic adenocarcinoma who developed anuric acute renal injury.

Objective: This study examined the role of lithium in the maintenance treatment of pediatric patients with bipolar I disorder (BP-I).

Method: Participants aged 7 to 17 years who presented with a manic or mixed episode received 24 weeks of lithium treatment in one of two multiphase studies, the Collaborative Lithium Trials (CoLT 1 and CoLT 2). Responders were randomized to continue lithium or to be cross-titrated to placebo for up to 28 weeks.

Objective: Ovarian reserve evaluation has been the focus of substantial clinical research for several years. This study aimed to examine the associations between markers of ovarian reserve and ovarian response.

Methods: This prospective study included 132 infertile women aged 24-48 years undergoing routine exploration during unstimulated cycles prior to the start of assisted reproductive technology (ART) treatments at our center from July 2015 to January 2017.

Objective: The primary objectives of this study were to evaluate the pharmacokinetics (PK) and tolerability of single and multiple doses of vortioxetine in children and adolescents with a depressive or anxiety disorder and to provide supportive information for appropriate dosing regimens for pediatric clinical trials.

Methods: This prospective, open-label, multinational, multisite, multiple-dose trial enrolled 48 patients (children and adolescents; 1:1 ratio) divided into 8 cohorts (4 adolescent and 4 child), with each cohort including 6 patients. The cohorts in each age group were assigned to receive one of four dosing regimens: vortioxetine 5, 10, 15, or 20 mg q.

Objective: For palliation of extrahepatic bile duct obstruction, self-expandable metal stents (SEMS) are superior to plastic stents in terms of stent patency and occurrence of stent dysfunction. We assessed health-related quality of life (HRQoL) after stent placement to investigate whether this also results in a difference in HRQoL between patients treated with a plastic stent or SEMS.

Patients And Methods: This randomized multicenter trial included 219 patients who were randomized to receive plastic stent (n=73) or SEMS [uncovered (n=75) and covered (n=71); n=146] placement.

Acaricide resistance is a major obstacle to the control of Rhipicephalus microplus. Historically, the indiscriminate use of chemical compounds has contributed to the selection of populations resistant to different classes of acaricides. Therefore, multiple acaricide resistance is an important threat to the chemical control of the cattle tick.

Background And Aims: Non-adherence to anti-tumour necrosis factor [TNF] agents in patients with inflammatory bowel disease [IBD] is a serious problem. In this study, we assessed risk factors for non-adherence and examined the association between adherence to anti-TNF agents and loss of response [LOR].

Methods: In this multicentre, 12-month observational study, outpatients with IBD were included.
