Automatic evaluation of Nail Psoriasis Severity Index using deep learning algorithm.

Nail psoriasis is a chronic condition characterized by nail dystrophy affecting the nail matrix and bed. The severity of nail psoriasis is commonly assessed using the Nail Psoriasis Severity Index (NAPSI), which evaluates the characteristics and extent of nail involvement. Although the NAPSI is numeric, reproducible, and simple, the assessment process is time-consuming and often challenging to use in real-world clinical settings. To overcome the time-consuming nature of NAPSI assessment, we aimed to develop a deep learning algorithm that can rapidly and reliably evaluate NAPSI, thereby providing numerous clinical and research advantages. We developed a dataset consisting of 7054 single fingernail images cropped from images of the dorsum of the hands of 634 patients with psoriasis. We annotated the eight features of the NAPSI in a single nail using bounding boxes and trained the YOLOv7-based deep learning algorithm using this annotation. The performance of the deep learning algorithm (DLA) was evaluated by comparing the NAPSI estimated using the DLA with the ground truth of the test dataset. The NAPSI evaluated using the DLA differed by 2 points from the ground truth in 98.6% of the images. The accuracy and mean absolute error of the model were 67.6% and 0.449, respectively. The intraclass correlation coefficient was 0.876, indicating good agreement. Our results showed that the DLA can rapidly and accurately evaluate the NAPSI. The rapid and accurate NAPSI assessment by the DLA is not only applicable in clinical settings, but also provides research advantages by enabling rapid NAPSI evaluations of previously collected nail images.

Orthopedic Applications of Single-photon Emission Computed Tomography/Computed Tomography in Identifying Pain Generators in the Pre- and Post-operative Patient

Postoperative and benign bone pathologies can sometimes be difficult to elicit on purely anatomical-based imaging. Single-photon emission computed tomography-computed tomography (SPECT-CT) is an established modality with emerging applications in the musculoskeletal field that combines cross-sectional structural imaging with the metabolic data. It is thought to offer certain clinical advantages to conventional imaging modalities as it can be sensitive to conditions before they appear as a structural abnormality. The aim of this pictorial review is to demonstrate the musculoskeletal applications of SPECT/CT in the pre- and post-operative orthopedic patient. The evidence for the musculoskeletal application of SPECT/CT is reviewed in various pre- and post-operative patients focusing on the advantages and disadvantages of this imaging modality alongside conventional imaging. Alongside this we present a series of musculoskeletal SPECT/CT cases in postoperative spinal and extremity joints identifying such pathologies as loosening, pseudoarthroses and prosthetic joint infection. We also include cases on the nonoperative joint identifying pain generators for targeted therapy. This review has shown that SPECT/CT can be a useful adjunct alongside other conventional imaging modalities in identifying musculoskeletal pain generators in the postoperative patient. It is especially useful in situations where anatomical imaging modalities alone provide insufficient diagnostic information or lack of symptomatic improvement. SPECT/CT is therefore likely to remain an complimentary investigative tool for unidentified musculoskeletal pain or for postoperative patients with metalwork in situ.

Remdesivir in solid organ transplant recipients with COVID-19: a systematic review and meta-analysis.

The use of remdesivir in solid organ transplant recipients (SOTRs) with coronavirus disease 2019 (COVID-19) has been studied. The present systematic review and analysis aimed to assess its effectiveness in this population. A comprehensive search of PubMed, Cochrane Library, Web of Science, Embase, medRxiv, and Google Scholar was conducted to identify relevant articles published up to April 2024. The quality of the included studies was evaluated using the Cochrane assessment tool. Data analysis was performed using the Comprehensive Meta-Analysis software ver. 3.0. The meta-analysis included seven eligible retrospective studies, involving a total of 574 SOTRs. The findings indicated no significant differences in mortality rate (odds ratio [OR], 1.19; 95% confidence interval [CI], 0.59-2.39), hospitalization rate (OR, 0.69; 95% CI, 0.10-4.79), need for mechanical ventilation (OR, 0.98; 95% CI, 0.44-2.18), or need for oxygen therapy (OR, 3.73; 95% CI, 0.75-18.34) between the groups that received remdesivir and those that did not. However, a statistically significant difference was observed in the rate of intensive care unit admissions between the two groups (OR, 2.39; 95% CI, 1.24-4.57). Our meta-analysis found that remdesivir offers no clinical benefits to SOTRs infected with COVID-19. Additional high-quality research is required to assess the potential clinical advantages of remdesivir for SOTRs with COVID-19.

Does the femoral component design modified in consideration of Asian anatomical characteristics fit better than the conventional design for Korean femora in reality?

We aimed to investigate the anatomical and clinical advantages of an Asian-specific femoral component design with a high femoral aspect ratio, compared with the conventional femoral component design. A retrospective analysis of the operation and outpatient clinic records of 239 knees operated on using an anatomically modified femoral component design (MFCD, Group A) and 153 knees operated on using a conventional femoral component design (CFCD, Group B) in Korean patients was performed. Three subgroups were created based on the mediolateral size of the two different femoral component designs. The geometric accommodation of each femoral component was assessed using intraoperatively measured femoral posterior condylar resection and posterior condylar trimming amounts. Clinical outcomes were assessed using a range of motion (ROM) and patient-reported outcome measurements. In the comparison between Groups A and B, the mean combined bilateral posterior condylar trimming (XPCT) was 2.91 [2SD: -4.12-9.94] and 1.45 [2SD: -5.89-8.80], and the median XPCT was 3 and 1.5. In the largest subgroup (subgroup 2), Groups A and B included 100 and 112 patients, all six posterior condylar resection and trimming parameters were significantly larger in Group A. Preoperative and postoperative ROM and Hospital for Special Surgery scores were similar between the two groups. Preoperative Western Ontario and McMaster Universities Arthritis Index (WOMAC) was higher in Group A. However, postoperative WOMAC was similar between the groups. Perioperative improvement in WOMAC index was significantly greater in Group B. The Asian-specific femoral component design resulted in more resection and trimming of the femoral posterior condyle than the conventional design despite it was not associated with different clinical outcomes. Surgeons should be aware of unexpected excessive posterior condylar resection and formation of large flexion gap when using femoral component design with high femoral aspect ratio.

High-Tech Parameters for the Evaluation of Signs and Symptoms of Dry Eye Disease: Identification of Clinical Cut-Offs and Agreement with Low-Tech Tests.

High-tech devices for the assessment of dry eye disease (DED) are increasingly available. However, the agreement between high- and low-tech parameters has been poorly explored to date. Trying to fill these gaps, we conducted a post hoc analysis on a recently published retrospective study on patients with DED receiving both low- and high-tech (Keratograph®) assessments, and treatment with different lubricating eyedrops. Six clinical questions were defined by the authors, considering literature gaps and their clinical experience, namely: (1) are NIKBUT-i and T-BUT interchangeable parameters? (2) What was the correlation between low- and high-tech parameters in untreated and treated patients with DED? (3) What was the correlation between signs and symptoms at baseline and during/after treatment? (4) Which parameters were better associated with symptoms? And with symptoms change over time? (5) What was the performance of NIKBUT-i and T-BUT in detecting clinically relevant changes? (6) What was the clinical advantage of adding other high- and low-tech parameters, respectively, to NIKBUT-i and T-BUT? Low-tech measures were the best descriptors ofthe Ocular Surface Disease Index (OSDI) at baseline. In contrast, high-tech assessments demonstrate better performance in detecting changes over time. The distribution of NIKBUT-i data was more dispersed than TBUT both at baseline and follow-up. At a fixed specificity of 80%, the sensitivity in detecting clinically relevant ameliorations of symptoms was 42% for NIKBUT-i and 25% for T-BUT. A battery of high-tech tests could detect 90% of clinical amelioration, compared with 45% with low-tech tests (p < 0.001). Correlation between low- and high-tech parameters in both treated and untreated patients is lacking. Low-tech measures are adequate for diagnostic purposes in DED, whereas high-tech showed better performances at follow-up, particularly when different tests are combined. Overall, poor interchangeability among parameters and agreement with symptoms was reported both with high- and low-tech assessments.

A Practical Approach to Full-Arch Implant Prosthesis Fabrication Utilizing 3D-Printed Surgical Guide Index.

This paper presents an efficient method for fabricating a full-arch implant prosthesis within one day, using a verification index through a three-dimensional (3D)-printed surgical guide. The technique involves the use of simple impression coping and laboratory analogs to ensure accurate prosthesis placement. Directly using 3D-printed surgical guides as a verification index simplifies and streamlines the procedure, offering a significant clinical advantage. This approach provides a clinically relevant advancement in prosthodontic practices by demonstrating a practical and instructive approach to enhance treatment outcomes.

Augmented Reality in Extratemporal Lobe Epilepsy Surgery.

Background: Epilepsy surgery for extratemporal lobe epilepsy (ETLE) is challenging, particularly when MRI findings are non-lesional and seizure patterns are complex. Invasive diagnostic techniques are crucial for accurately identifying the epileptogenic zone and its relationship with surrounding functional tissue. Microscope-based augmented reality (AR) support, combined with navigation, may enhance intraoperative orientation, particularly in cases involving subtle or indistinct lesions, thereby improving patient outcomes and safety (e.g., seizure freedom and preservation of neuronal integrity). Therefore, this study was conducted to prove the clinical advantages of microscope-based AR support in ETLE surgery. Methods: We retrospectively analyzed data from ten patients with pharmacoresistant ETLE who underwent invasive diagnostics with depth and/or subdural grid electrodes, followed by resective surgery. AR support was provided via the head-up displays of the operative microscope, with navigation based on automatic intraoperative computed tomography (iCT)-based registration. The surgical plan included the suspected epileptogenic lesion, electrode positions, and relevant surrounding functional structures, all of which were visualized intraoperatively. Results: Six patients reported complete seizure freedom following surgery (ILAE 1), one patient was seizure-free at the 2-year follow-up, and one patient experienced only auras (ILAE 2). Two patients developed transient neurological deficits that resolved shortly after surgery. Conclusions: Microscope-based AR support enhanced intraoperative orientation in all cases, contributing to improved patient outcomes and safety. It was highly valued by experienced surgeons and as a training tool for less experienced practitioners.

Economic effects of next-generation sequencing diagnostics in unspecific sepsis patients - a budget impact analysis from the healthcare providers' perspective in Germany.

Next-generation sequencing (NGS) tools have clinical advantages over blood culture but are more expensive. This study assesses the budget impact and break-even point of NGS testing costs from a healthcare provider's perspective in Germany. The budget impact was calculated based on aggregated data of German post-operative surgery cases. Simulated cost savings were calculated based on a simulated reduction in hospital length of stay (LOS) of four or eight days with a positivity rate of 71% and compared to the costs of one (scenario A) or two tests (scenario B) per case. Furthermore, the break-even point of the cost of two tests compared to saved costs through shortened LOS was conducted. For 9,450 cases, an average budget impact for scenario A and scenario B of €1,290.41 [95% CI €1,119.64 - €1,461.19] and - €208.59 [95% CI - €379.36 - - €37.81] was identified for gastrointestinal and kidney surgery cases, and €1,355.58 [95% CI €1,049.62 - €1,661.55] and €18.72 [95% CI - €324.69 - €287.24] for vascular artery surgery cases, respectively. The break-even analysis showed that using two tests per case could achieve a minimum positive contribution margin with an average of 1.9 tests per case across the study population. The results revealed a positive budget impact for one NGS test and a slightly negative budget impact for two NGS tests per case. Findings suggest that largest cost savings are generated for more severe cases and are highly dependent on the patient population.

Natural biomaterials in the management of the aortic valve pathology. Biomedical and clinical aspects: A review.

Heart valve diseases are a prevalent cardiovascular pathology worldwide, affecting nearly 2.5% of the population. Degenerative aortic stenosis is the most common form of heart valve disease. The treatment options include surgical or transcatheter procedures. There are two main categories of valve prostheses available: mechanical heart valves constructed from synthetic materials and bioprosthetic heart valves made from natural biomaterials. The choice of valve type depends on various factors, including the underlying medical condition, suitability for anticoagulation, valve durability, and the patient's age and preferences. Mechanical heart valves have the advantage of long-term durability. However, patients receiving mechanical implants are subjected to lifelong anticoagulation therapy with an increased risk of thromboembolism and bleeding. Natural biomaterials do not require long-term anticoagulation. However, they experience degenerative changes leading to structural valve deterioration that may require reoperation. The purpose of this article is to review the role of natural biological materials used for aortic valve replacement or repair, assess their biomedical and clinical advantages and limitations, and analyze the direction and perspectives of future development.

Effect of central dialysis fluid delivery system on markers of inflammation in hemodialysis patients

BackgroundThe utilization of ultrapure dialysate has been shown to decrease dialysate contamination and mitigate inflammatory responses. The central dialysate delivery system (CDDS) has the potential to attain a level of purity similar to ultrapure dialysate. Nevertheless, there is limited research examining the impact of CDDS on inflammation in comparison to single-patient dialysis fluid delivery system(SPDDS). This study aims to investigate the effects of CDDS utilizing ultrapure dialysate on ameliorating the microinflammatory state in hemodialysis patients.MethodA retrospective cohort clinical study enrolled a total of 125 hemodialysis patients, with 58 patients from the CDDS unit and 67 patients from the SPDDS unit. Each participant was monitored for a period of 6 months, and the repeated measurement data was analyzed using a generalized linear mixed models (GLMM).ResultsThe average age of the studty cohort was 56.22 ± 12.64 years. The GLMM analysis showed a significant time*group interaction effect on hs-CRP changes over the follow-up period (β = -1.966, FTime* CDDS group = 13.389, P < 0.001). A linear mixed model analysis with random slope showed that a different slope was observed between CDDS group and SPDDS group (βCDDS =—0.793; βSPDDS = 0.791), indicating a decreased hs-CRP levels in CDDS group, while increased in the SPDDS group over the follow-up period. However, no significant time*group interaction effect were observed on albumin and β2-microglobulin levels during follow-up period(β2-microglobulin: β = -0.658, FTime* CDDS group = 1.228, P = 0.269; albumin: β = 0.012, FTime* CDDS group = 1.429, P = 0.233).ConclusionUsing ultrapure dialysate in the CDDS is associated with an improvement in hs-CRP levels compared to standard dialysate, which might confer long-term clinical advantages.

Clinical advantages of incorporating predicted weekly anatomy in IMPT optimization with reduced setup error

AbstractBackgroundIn head and neck (H&amp;N) cancer treatment, a conventional setup error (SE) of 3mm is often used in robust optimization (cRO3mm). However, cRO3mm may lead to excessive radiation doses to organs at risk (OARs) and does not purposefully compensate for interfractional anatomy variations.PurposeThis study introduces a method using predicted images from an anatomical model and a reduced 1mm SE uncertainty for robust optimization (aRO1mm), aiming to decrease the dose to OARs without affecting the coverage of the clinical target volume (CTV).MethodsThis retrospective study involved 10 nasopharynx radiotherapy patients. Validation CT scans (vCT) from treatment weeks 1 to 6 were analyzed. A predictive anatomical model, designed to capture the average anatomical changes over time, provided predicted CT images for weeks 1, 3, and 5. We compared three optimization scenarios: (1) aRO1mm, using three predicted images with 1mm setup shift and 3% range uncertainty, (2) cRO3mm, with a robust 3mm setup shift and 3% range uncertainty, and (3) cRO1mm, a robust 1mm setup shift and 3% range uncertainty. The accumulated dose to CTVs and serial organs was evaluated under these uncertainties, while parallel OARs were assessed using the accumulated nominal dose (without errors).ResultsThe accumulated volume receiving 94% of the prescribed dose (V94) for CTVs in cRO3mm exceeded 98%, meeting the clinical goal. For high‐risk CTV, the minimum V94 was 96.44% in aRO1mm and 94.05% in cRO1mm. For low‐risk CTV, these values were 97.68% in aRO1mm and 97.15% in cRO1mm. When comparing aRO1mm to cRO3mm on OARs, aRO1mm reduced normal tissue complication probability (NTCP) for grade 2 xerostomia and dysphagia by averages of 3.67% and 1.54%, respectively.ConclusionaRO1mm lowers the radiation dose to OARs compared to the traditional approach, while maintaining adequate dose coverage on the target area. This method offers an improved strategy for managing uncertainties in radiation therapy planning for H&amp;N cancer, enhancing treatment effectiveness.

Vitamin D Status among Patients Visiting an Urban Tertiary Care Hospital, Dhaka

Background: Majority of the Bangladeshi population lives in an areas receiving ample sunshine throughout the year. Despite this fact multiple studies have shown wide prevalence of vitamin D deficiency in our country in all ages and both sexes. Adequate vitamin D status has an important clinical advantage for maintaining various activities as well as preventing diseases. In this lab based retrospective study, it was determined the prevailing condition of vitamin D deficiency among adult patients visiting MH Samorita Hospital and Medical College outdoor. The present study aimed to focus on assessing Vitamin D status of adult patients visited a tertiary care hospital of Dhaka city. Materials and methods: This was a retrospective study. A total of 72 cases were chosen by random sampling with records of vitamin D status, age and sex from July to December, 2022.The results were statistically analyzed with Statistical Packages for Social Science (SPSS-24). Results: Out of total subject (n=72) none of them showed toxic serum concentration of vitamin, 12.5 % had sufficient, 23.6% had insufficient and 63.9% had deficient levels of vitamin D. Gender wise comparison of vitamin D status showed male patients, 28.3% were deficient in vitamin D, 47.1% were insufficient, and a substantial 77.8% had sufficient levels. In contrast, a much higher proportion of female patients were deficient (71.7%) or insufficient (52.9%) in vitamin D, with only 22.2% having sufficient levels. According to age wise distribution, the highest percentage of vitamin D deficiency (58.7%) was observed in the youngest age group (18-30 years), while the proportion decreased in older age groups (30.4% for 31-50 years and 10.9% for 51-65 years). Conclusion: Vitamin D is an important vitamin which impacts many systems of the body .This study indicates that 63.9 % of subjects are vitamin D deficient which is very much alarming. So, it becomes paramount to further scrutinize the associated factors apart from age and gender. To this end, further studies are needed. IAHS Medical Journal Volume 6(2) December 2023; 68-72

Ultrasound-Guided Lumbar Plexus-Sciatic Nerve Blocks Versus Epidurals for Orthopaedic Surgeries: A Study to Compare the Competency of Novice Anaesthesiology Residents in a High-Volume Level 1 Trauma Centre.

The relative merits of peripheral nerve blocks (PNB) over central neuraxial anaesthesia and the advantages of the above two techniques over general anaesthesia for surgical interventions of the lower limb are well established. The competency of anaesthetic trainees in a high-volume level 1 trauma centre in administering dual ultrasound and nerve stimulator-guided lumbar plexus-sciatic nerve block(DUNLuPS) vs. epidural anaesthesia (EA) was compared by reporting the adequacy of anaesthesia with the two techniques, time taken for the performance of block, time of onset of sensoryblock (TOSB), and time of onset of motor block (TOMB). This prospective, randomized, study enrolled 92 patients aged 18-80 years with lower limb fractures admitted in trauma triage and scheduled for surgery. Thepatients were randomly allocated equally into the EA group and the DUNLuPS group. A total of 20 anaesthesia trainees in the third year of residencywith clinical experience of more than 15 independent lumbar plexus-sciatic nerve blocks were included in the study.A volume of 20 ml of 0.5% ropivacaine was administered in the lumbar plexus (Shamrock technique) but the volume used for sciatic nerve (subgluteal approach) was varied so that the cumulative dose did not exceed 3 mg/kg. For each block, the onset of nerve blockade was assessed every five minutes, and the assessments continued for an additional 30 minutes after the nerve blocks were finished. Clinical characteristics and adequacy of anaesthesia were comparable, i.e., 95.65% and93.47% success in the EA (n = 46) and DUNLuPS (n = 46) groups, respectively. Performance time was significantly more in the DUNLuPS group but followed by significantly less TOSB and TOMB. The time for the first analgesic request was 351.63 ± 148.70 minutes in the DUNLuPS group and 147.60 ± 52.65 minutes in the EAgroup (p < 0.0001). Both EA and DUNLuPS provide effective and comparable intra-operative anaesthesia for orthopaedic lower limb surgeries (OLLS) when administered by residents with more than two years of experience (third year of residency)in ultrasound-guided regional nerve blocks in a high-volume level 1 trauma centre. Statistically significant differences in the block performance characteristicshad no clinical advantage as it was compensated by the faster onset time in the DUNLuPS group. Post-operative pain management was better in the DUNLuPS group, sothe practice and conduct of anaesthesia for trauma patients should focus on the establishment of "block rooms" and timely training of residents in the former so that the advantages can be extended to the patient population.

Transanal intersphincteric under direct view in the jackknife position combined with laparoscopic total mesorectal excision for treating ultra-low rectal cancer.

To investigate the effect and clinical advantage of transanal intersphincteric (ISR) under direct view in the jackknife position combined with laparoscopic total mesorectal excision (TME) for treating ultra-low rectal cancer. Additionally, the feasibility of this surgical technique was evaluated. This was a retrospective, single-center, single-arm pilot study. Ten patients with ultra-low rectal cancer underwent treatment by the same surgical team for direct view transanal ISR combined with laparoscopic TME in the Department of Anorectal Surgery, Huizhou Central People's Hospital between January 2021 and June 2021. The relevant clinical data were collected and analyzed. All the patients underwent complete mesenteric resection without conversion to laparotomy. The circumferential and distal resection margins (CRM and DRM) were negative. The mean distance between the lower margin of the tumor and the anal margin was 2.8 ± 0.8 cm, and the mean margin of distal resection was 1.2 ± 0.2 cm. TNM pathological stages I, II, III, and IV were observed in 6, 2, 2, and 0 cases, respectively. The median follow-up period was 15 months (interquartile range, 8 months). The mean Wexner and Low Anterior Resection Syndrome scores at 12 months after ileostomy were 8.1 ± 2.1 and 22.4 ± 5.7, respectively. Transanal ISR under direct view in the jackknife position combined with laparoscopic TME is safe and feasible for the treatment of ultralow rectal cancer.

Qualitative focus group study of interprofessional healthcare providers to inform the development of a virtual psychoeducational training program for the treatment of childhood interpersonal trauma

ABSTRACT The shortage of adequately trained healthcare providers (HCPs) able to treat adults who have experienced childhood interpersonal trauma (CIT) is a pressing concern. This study explored HCPs’ training needs for a trauma-focused psychoeducational group intervention and the potential barriers and facilitators to accessing such training. Three 1-hour focus group sessions were conducted with HCPs (n = 17) from two urban and one rural community healthcare organization serving diverse populations in Ontario, Canada, including under-housed people, women struggling with mental health and addiction, and LGBTQ+ populations. On average, participants had 2.4 years in their current role and 18.1 years of mental health field experience. Thematic analysis revealed key findings: a strong clinical need for trauma services, accessible training programs, and broadly applicable interventions relevant for diverse populations. Notably, participants emphasized the clinical advantages and increased accessibility of a virtual training programs focused on psychoeducational treatment interventions, particularly within community-based healthcare settings. This study highlights the potential of a virtual psychoeducational training programs for HCPs to address this critical gap in healthcare provision for individual with CIT. It also underscores the need to move beyond training program development and focus on implementation and sustainability of interventions in clinical practice.

Assessing the clinical advantage of opioid-reduced anesthesia in thoracoscopic sympathectomy: a prospective randomized controlled trial

BackgroundOpioid-reduced multimodal analgesia has been used clinically for many years to decrease the perioperative complications associated with opioid drugs. We aimed to assess the clinical effects of opioid-reduced anesthesia during thoracoscopic sympathectomy.MethodsSurgical patients (n = 151) with palmar hyperhidrosis were randomly divided into control (Group C, 73 patients) and test (Group T, 78 patients) groups. All patients were administered general anesthesia using a laryngeal mask. In Group C, patients received propofol, fentanyl, and cisatracurium for anesthesia induction, and maintenance was achieved with propofol and remifentanil, along with mechanical ventilation during the operation. In Group T, anesthesia was induced with propofol, dezocine, and dexmedetomidine (DEX) and maintained with propofol, DEX, and an intercostal nerve block, along with spontaneous breathing throughout the operation. Perioperative complications related to opioid use include hypotension, bradycardia, hypertension, tachycardia, hypoxemia, nausea, vomiting, urine retention, itching, and dizziness were observed. To assess the impact of these complications, we recorded and compared vital signs, blood gas indices, visual analogue scale (VAS) scores, adverse events, and patient satisfaction between the two groups.ResultsPerioperative complications related to opioid use were similar between groups. There were no significant differences in the type of perioperative sedation, analgesia index, respiratory and circulatory indicators, blood gas analysis, postoperative VAS scores, adverse reactions, propofol dosage, postoperative recovery time, and patient satisfaction.ConclusionsIn minimally invasive surgeries such as thoracoscopic sympathectomy, opioid-reduced anesthesia was found to be safe and effective; however, this method did not demonstrate clinical advantages.Trial registrationChinese Clinical Trial Register: ChiCTR2100055005, on December 30, 2021.

Efficacy and safety of ticagrelor monotherapy following a brief DAPT vs. prolonged 12-month DAPT in ACS patients post-PCI: a meta-analysis of RCTs.

As per current guidelines, acute coronary syndrome (ACS) patients who undergo percutaneous coronary intervention (PCI) should be started on dual antiplatelet therapy (DAPT) for a period of 12months. To assess the efficacy and safety of brief DAPT (up to 3months) succeeded by ticagrelor monotherapy compared with a 12-month DAPT in ACS patients following PCI. We systematically searched Cochrane, Embase, and PubMed to find relevant randomized clinical trials. Examined outcomes included the incidence of major adverse cerebrovascular and cardiovascular events (MACCE), bleeding events, and the composite incidence of net adverse clinical events (NACE). Our primary analysis included 21,927 ACS patients from six RCTs. Our pooled results indicate that following PCI in individuals with ACS, brief DAPT followed by ticagrelor did not increase the risk of MACCE (OR 0.92, 95% CI 0.79-1.07) but significantly reduced the risk of minor or major bleeding (OR 0.52, 95% CI 0.44-0.62) and NACE (OR 0.71, 95% CI 0.59-0.86) compared with a long-term DAPT within a follow-up of 12months. Brief DAPT followed by ticagrelor monotherapy is superior to a 12-month DAPT in offering a net clinical advantage in ACS patients following PCI.

Oncological outcomes of minimally invasive surgery in non-endometrioid endometrial Cancer patients with varying prognostic risks: a retrospective cohort study based on the ESGO/ESTRO/ESP 2020 guidelines

BackgroundNon-endometrioid endometrial carcinomas (NEEC) are characterized by their rarity and adverse prognoses. This study evaluates the outcomes of open versus minimally invasive surgery (MIS) in NEEC patients stratified by prognostic risks according to the 2020 ESGO-ESTRO-ESP risk classification guidelines.MethodsA retrospective analysis was performed on 99 NEEC patients who underwent initial surgery at Fujian University Cancer Hospital. Patients were categorized into two groups: those undergoing MIS and those undergoing open surgery. We compared disease-free survival (DFS) and overall survival (OS) between these groups. Cox regression analysis was employed to identify risk factors for DFS, which were further validated via bootstrap statistical methods.ResultsThe study included 31 patients in the MIS group and 68 in the open surgery group. The demographics and clinical characteristics such as age, body mass index, comorbidities, histological subtypes, and FIGO stage were similar between groups (P > 0.05). The MIS group experienced ten recurrences (1 vaginal, 2 lymph nodes, 7 distant metastases), whereas the open surgery group had seven recurrences (1 vaginal, 3 lymph nodes, 1 pelvis, 2 distant metastases), yielding recurrence rates of 10.3% versus 25.6% (P = 0.007). Besides lymphovascular space invasion (LVSI), surgical approach was also identified as an independent prognostic factor for DFS in high-risk patients (P = 0.037, 95% CI: 1.062–7.409). The constructed nomogram demonstrated a robust predictive capability with an area under the curve (AUC) of 0.767. Survival analysis for high- and intermediate-risk patients showed no significant differences in OS between the two groups (Phigh risk = 0.275; Pintermediate−risk = 0.201). However, high-risk patients in the MIS group exhibited significantly worse DFS (P = 0.001).ConclusionThis investigation is the inaugural study to assess the impact of surgical approaches on NEEC patients within the framework of the latest ESGO-ESTRO-ESP risk classifications. Although MIS may offer clinical advantages, it should be approached with caution in high-risk NEEC patients due to associated poorer DFS outcomes.

SUS 2 - Routine histological examination of haemorrhoidal tissue – an unnecessary environmental and economic expense?

Abstract Background Modern, less invasive methods of haemorrhoid treatment, such as haemorrhoid artery ligation and radiofrequency ablation, are increasingly employed. These do not yield specimens for histological analysis. However, when open haemorrhoidectomy is performed, even in the absence of suspicious operative features and in low-risk patients, the haemorrhoid specimen is routinely sent. This has both environmental and financial costs in an increasingly pressured NHS, and negatively impacts sustainability with no clinical advantage. Methods We retrospectively studied 112 open haemorrhoidectomies performed at our UK hospital from February 2018 to June 2023, reviewing clinic letters, operation notes and post-operative histology. Aims To assess the frequency of incidental pathology identified during routine histological assessment, and the associated financial costs and carbon footprint generated. Results 112 open haemorrhoidectomies were performed in the 5-year study period. In total, two patients with risk factors for AIN/Anal cancer were identified. There were no documented concerns of abnormal intra-operative findings. Histology mainly revealed haemorrhoid tissue alone (103) and benign polyps (8). AIN3 was detected in one of the high-risk patients. The cost per histology specimen was £93.32 (Total cost £10,451.84). Each specimen is estimated to generate 0.29kg of Carbon Dioxide equivalents (Total 32.48kg CO2e). Conclusion Routine histological assessment of haemorrhoidectomy specimens is time-consuming, expensive and has an avoidable carbon footprint for a low detection of incidental pathology. Our study suggests that histology should be reserved for patients with risk factors for AIN/Anal cancer, or concerning intra-operative findings. Larger scale studies, and development of national guidelines would aid clinician decision-making.
