Single-Centre Retrospective Study on the Effects of Bariatric Surgery on Nocturia.

PURPOSE: The incidence of nocturia is increased in obesity, which causes significant negative impact on quality of life. Bariatric surgery is a reliable method in which to achieve major weight loss and this study aims to determine the effect of bariatric surgery on nocturia and other lower urinary tract symptoms (LUTS) in men and women. MATERIALS AND METHODS: Retrospective study of patients undergoing bariatric surgery had pre- and post-operative questionnaires using the validated International Prostate Symptoms Score (IPSS) to assess nocturia between 2018 and 2021. The primary outcome was effect of bariatric surgery on nocturia RESULTS: A total of 99 patients were included with median age of 52.9 (44.9-60.2) and 83.8% being female. The median weight was 129.9kg (110-151.9) and median BMI was 45.5 (41.4-53.4). Improvements were demonstrated in all criteria assessed in IPSS and nocturia significantly improved with a decrease in 1.14 points (p < 0.05). Linear regression analysis showed that, in the post operative period assessed, there were no significant effect on variables measured such as obstructive sleep apnoea, type 2 diabetes on the effect of IPSS post-bariatric surgery within the follow-up period of 4-6 months. CONCLUSION: Bariatric surgery can have significant improvements on nocturia symptoms in men and women with obesity. This is another means in how bariatric surgery can reduce morbidity and improve quality of life.

Red Out: Bleeding During Robotic Retroperitoneal Lymph Node Dissection and Strategies To Manage It.

Robotic retroperitoneal lymph node dissection is emerging as an attractive minimally invasive technique to remove residual and recurrent retroperitoneal masses in patients with germ cell malignancies. It has huge potential benefits for patients in terms of lower rates of blood loss, ileus, postoperative pain, and scarring, and faster return to full activity. Inadvertent injury to the great vessels, lumbar tributaries, and other vessels is not uncommon and requires a calm but strategic management response. A thorough knowledge of the standard anatomy, specific pathology, and anatomic variations will help robotic surgeons in managing intraoperative haemorrhage. We describe the anatomy of the retroperitoneal vessels, surgical case selection, and the technical and nontechnical skills essential for success in this complex and high-risk procedure. Patient summary: Robot-assisted surgical removal of lymph nodes from the area behind the abdominal cavity is a complex operation that has minimal bleeding if all goes well. However, as it involves operating on the major abdominal blood vessels, there is a risk of life-threatening bleeding that the operating team must be able to rapidly control. Effective teamwork and a range of advanced technical skills are required to respond to any serious bleeding.

Provision of mental health support for medical students.

Studying medicine at university requires hard work and motivation. The medical school curriculum is vast, and as well as being academically rigorous, also holds emotional challenges. This can predispose students to mental health issues, which include depression and suicidal thinking. Since these are significant issues, we feel it is important to highlight the reasons behind them, and the options available to students to deal with them.

Analysis of the first 2645 registrations at the research registry®: A global repository for all study types involving human participants.

BACKGROUND: The Declaration of Helsinki has called for the registration of all research studies involving human participants. Despite this, prior registries did not allow registration certain study types, or retrospective registration. The Research Registry® (www.researchregistry.com) was established in 2015 to provide a venue of registration for any study involving human participants. METHODS: and analysis: This retrospective database analysis describes the first 3000 registrations received by the Research Registry®. Since the launch of the Registry in 2015, we have collected data on each registration and excluded inappropriate registrations through a weekly curation process. The characteristics of all studies registered is presented. Each registration was marked against a quality score by two researchers acting independently, and we describe how this has changed over time. No ethical approval was required for this data only study including no human participants. RESULTS: Of 3000 registrations, we included 2645 that were submitted to the registry between February 2015 and October 2017. The number of registrations increased year on year, and we now receive between 60 and 80 registrations per month. One fifth of registrations were from China (537 [20.3%]). Retrospective observational studies were most commonly registered (1125 [42.5%]), and studies included in excess of 20 million patients (median 80 [IQR:25-200]). The quality score of registrations improved over the time (Kruskal-Wallis p < 0.05), and the 'control/comparator' component of the quality score was most poorly completed (completed by 1199 [54%]). CONCLUSION: The Research Registry® has received registrations on over 2500 registrations, including in excess of 20 million patients, with the quality of registrations improving over time. Retrospective observational studies and case series are the most commonly registered.

Challenges of transcultural placements: foster parent perspectives.

A random sample of licensed foster parents in a central Canadian province was asked, "What are the challenges of fostering children who have different values, beliefs, and traditions than you?" In response to this question, 49 unique responses were made and grouped together by foster parents. Seven themes emerged from the analysis: understanding, respecting, learning, compromising, disagreements, child's feelings, and teaching. Several differences were found between the literature and study participants, suggesting areas worthy of future research.

A context-informed approach to the study of negative-feedback seeking in depression.

The purpose of the current study was to examine the link between negative-feedback seeking (NFS) and depression using a behavioural task that addressed many of the limitations of existing measures of NFS, to use a remitted-depressive design to determine whether NFS is a temporary or stable feature of depression, and to examine the role of personality and contextual variables (e.g., marital quality, spousal characteristics) in NFS. Using a sample of 59 couples (12 wife currently depressed, 20 wife remitted-depressed, and 27 wife never-depressed), we designed a task that correlated with an established measure of NFS and was able to distinguish between non-depressed and currently depressed wives. Using this behavioural task, we found that NFS is stably associated with depression and that relationship and partner characteristics may protect depressed individuals from engaging in destructive interpersonal patterns.

Estimating blood loss: can teaching significantly improve visual estimation?

OBJECTIVE: Visually estimated blood loss has long been known to be imprecise, inaccurate, and often underestimated, which may lead to delayed diagnosis and treatment. Our purpose is to determine whether a brief didactic course can improve visually estimated blood loss and whether prior clinical experience influences estimation of blood loss. METHODS: Reconstituted whole blood was obtained from the blood bank, and simulated scenarios with known measured blood loss were created using common surgical materials. Visually estimated blood loss was performed by medical personnel before and after a 20-minute didactic session. Percent errors of estimated blood loss were calculated and comparisons were made before and after the lecture. The effects of actual blood volume and clinical experience on estimation of blood loss were assessed. RESULTS: A total of 53 participants assessed 7 scenarios. There were significant reductions in error for all scenarios. Median percent error in estimated blood loss was not influenced by clinical experience, either before or after the didactic session. Blood loss tends to be overestimated at low volumes and underestimated at high volumes. CONCLUSION: Error in estimating blood loss is dependent on actual blood loss volume. Medical students and experienced faculty demonstrate similar errors, and both can be improved significantly with limited instruction. This educational process may assist clinicians in everyday practice to more accurately estimate blood loss and recognize patients at risk for hemorrhage-related complications.
