Exploratory investigation of virtual lesions in gastrointestinal endoscopy using a novel phase-shift method for three-dimensional shape measurement.

Accurate measurement of the size of lesions or distances between any two points during endoscopic examination of the gastrointestinal tract is difficult owing to the fisheye lens used in endoscopy. To overcome this issue, we developed a phase-shift method to measure three-dimensional (3D) data on a curved surface, which we present herein. Our system allows the creation of 3D shapes on a curved surface by the phase-shift method using a stripe pattern projected from a small projecting device to an object. For evaluation, 88 measurement points were inserted in porcine stomach tissue, attached to a half-pipe jig, with an inner radius of 21 mm. The accuracy and precision of the measurement data for our shape measurement system were compared with the data obtained using an Olympus STM6 measurement microscope. The accuracy of the path length of a simulated protruded lesion was evaluated using a plaster model of the curved stomach and graph paper. The difference in height measures between the measurement microscope and measurement system data was 0.24 mm for the 88 measurement points on the curved surface of the porcine stomach. The error in the path length measurement for a lesion on an underlying curved surface was <1% for a 10-mm lesion. The software was developed for the automated calculation of the major and minor diameters of each lesion. The accuracy of our measurement system could improve the accuracy of determining the size of lesions, whether protruded or depressed, regardless of the curvature of the underlying surface.

Immunoglobulin G4 -related gastrointestinal disease associated with type 1 autoimmune pancreatitis: A case report.

Immunoglobulin G4 (IgG4)-related diseaseis a systemic inflammatory condition of unknown etiology characterized by increases in serum IgG4 and in the number of IgG4-positive cells in affected tissues. One of the commonly involved locations is the pancreas; this condition is known as type 1 autoimmune pancreatitis (AIP). Type 1 AIP, which shows a biliary stricture in the intrapancreatic bile duct, can be misdiagnosed as a malignancy due to similar cholangiography findings and clinical presentation. In rare cases complicated by post-bulbar duodenal ulcers, differentiating between type 1 AIP and malignancies is even more difficult. An 81-year-old male was referred to our hospital for the treatment of a pancreatic head mass and obstructive jaundice. Serological and radiological findings were consistent with both type 1 AIP and a malignancy. Gastroduodenoscopy revealed a post-bulbar duodenal ulcer with endoscopic features that evoked malignant duodenal invasion. Although biopsies were negative for malignant cells, subsequent bleeding from the lesion suggested the progression of malignancy, which led to surgical resection. Pancreatoduodenectomy and pathological examination indicated that type 1 AIP was present. Simultaneously, the involvement of IgG4-related disease in the ulcerative lesion was suggested. To our knowledge, this is the first reported case of type 1 AIP complicated by post-bulbar duodenal ulcers, which was misdiagnosed as malignancy and considered an IgG4-related gastrointestinal disease associated with type 1 AIP.

Updated techniques and evidence for endoscopic ultrasound-guided tissue acquisition from solid pancreatic lesions.

Endoscopic ultrasound-guided tissue acquisition (EUS-TA), including fine-needle aspiration (EUS-FNA) and fine-needle biopsy (EUS-FNB), has revolutionized specimen collection from intra-abdominal organs, especially the pancreas. Advances in personalized medicine and more precise treatment have increased demands to collect specimens with higher cell counts, while preserving tissue structure, leading to the development of EUS-FNB needles. EUS-FNB has generally replaced EUS-FNA as the procedure of choice for EUS-TA of pancreatic cancer. Various techniques have been tested for their ability to enhance the diagnostic performance of EUS-TA, including multiple methods of sampling at the time of puncture, on-site specimen evaluation, and specimen processing. In addition, advances in next-generation sequencing have made comprehensive genomic profiling of EUS-TA samples feasible in routine clinical practice. The present review describes updates in EUS-TA sampling techniques of pancreatic lesions, as well as methods for their evaluation.

Uso y complicaciones del cateterismo urinario en salas de cuidados moderados de un hospital universitario

Introducción: El cateterismo urinario es un procedimiento frecuente y en ocasiones es utilizado por fuera de las indicaciones aceptadas para el mismo. Esto aumenta el riesgo de complicaciones vinculadas a su uso, por lo que pueden ser prevenibles. El objetivo del estudio es conocer las características del uso de cateterismo urinario en pacientes ingresados en salas de cuidados moderados de un hospital universitario del tercer nivel de atención, determinar la frecuencia, duración e indicaciones más frecuentes, así como evaluar la presencia de complicaciones asociadas al mismo Metodología: Estudio de corte transversal, realizado en salas de cuidados moderados de un hospital terciario y universitario de Montevideo, Uruguay, el 21 de diciembre de 2022. Se incluyeron pacientes hospitalizados que presentaban o presentaron catéter vesical en la presente internación y se completó la recolección de variables mediante la revisión de la historia clínica. Resultados: De 155 pacientes ingresados en salas de cuidados moderados, a 26 (16,7%) les fue colocado un catéter urinario. La mediana de edad fue 61 años, 80% eran de sexo masculino. La mediana de internación fue de 22 días. En todos los pacientes se utilizó sonda vesical y el 54% fue colocado en el Departamento de Emergencia. En el 46% de los pacientes no se encontró indicación escrita de colocación en la historia clínica. En 50% de los casos no está especificado el motivo de indicación de sonda vesical, mientras que las indicaciones identificadas más frecuentes fueron el control de diuresis (27%) y la desobstrucción de vía urinaria baja (23%). La duración de cateterismo fue de una mediana de 13,5 días, mientras que el 27% de los pacientes la usaron más de 30 días. 35% de los pacientes presentaron complicaciones vinculadas a la sonda vesical, en su mayoría no infecciosas (27%) y 15% presentaron infección urinaria. Estos pacientes tuvieron una duración de cateterismo mayor a los que no presentaron complicaciones (23 vs 10 días, p=0,411). Conclusiones: El catéter vesical fue utilizado en un porcentaje no despreciable de pacientes ingresados en salas de cuidados moderados, de forma prolongada y frecuentemente sin indicación precisa, lo cual expone a un riesgo aumentado de complicaciones vinculadas.

Introduction: Urinary catheterization is a frequent procedure and is sometimes used outside of its accepted indications. This increases the risk of complications related to its use, so they may be preventable. The objective of this study is to know the characteristics of the use of urinary catheterization in patients admitted to moderate care wards of a tertiary care university hospital, to determine the frequency, duration and most frequent indications, as well as to evaluate the presence of associated complications. Methodology: Cross-sectional study, carried out in moderate care wards of a tertiary care and university hospital in Montevideo, Uruguay, on December 21, 2022. Hospitalized patients who present or presented a bladder catheter during the present hospitalization were included, and the collection of variables was completed by reviewing the medical history. Results: Of 155 patients admitted to moderate care wards, 26 (16.7%) had a urinary catheter placed. The median age was 61 years, 80% were male. The median hospitalization was 22 days. In all patients a bladder catheter was used and 54% were placed in the Emergency Department. In 46% of the patients, no written indication for placement was found in the clinical history. In 50% of cases, the reason for indicating the bladder catheter is not specified, while the most frequent indications identified were diuresis control (27%) and lower urinary tract obstruction (23%). The duration of catheterization was a median of 13.5 days, while 27% of the patients used it for more than 30 days. 35% of the patients presented complications related to the bladder catheter, mostly non-infectious (27%) and 15% presented urinary tract infection. These patients had a longer duration of catheterization than those without complications (23 vs 10 days, p=0,411). Conclusions: The bladder catheter was used in a non-negligible percentage of patients admitted to moderate care wards, for a long time and often without a precise indication, which exposes them to an increased risk of related complications.

Introdução: O cateterismo urinário é um procedimento frequente e às vezes é usado fora de suas indicações aceitas. Isso aumenta o risco de complicações relacionadas ao seu uso, portanto, podem ser evitáveis.

Resultados: Dos 155 pacientes admitidos em enfermarias de cuidados moderados, 26 (16,7%) tiveram um cateter urinário colocado. A idade média foi de 61 anos, 80% eram do sexo masculino. A mediana de internação foi de 22 dias. Em todos os doentes foi utilizada sonda vesical e 54% foram internados no Serviço de Urgência. Em 46% dos pacientes, nenhuma indicação escrita para colocação foi encontrada na história clínica. Em 50% dos casos não é especificado o motivo da indicação da sonda vesical, enquanto as indicações mais frequentes identificadas foram controle da diurese (27%) e desobstrução do trato urinário inferior (23%). A duração do cateterismo foi em média de 13,5 dias, enquanto 27% dos pacientes o utilizaram por mais de 30 dias. 35% dos pacientes apresentaram complicações relacionadas ao cateter vesical, em sua maioria não infecciosas (27%) e 15% apresentaram infecção urinária. Esses pacientes tiveram uma duração mais longa de cateterismo do que aqueles sem complicações (23 vs 10 dias, p=0,411). Conclusões: A sonda vesical foi utilizada em percentual não desprezível de pacientes internados em quartos de cuidados moderados, por tempo prolongado e muitas vezes sem indicação precisa, o que os expõe a um risco aumentado de complicações associadas.

A case report of Löffler's endocarditis with right ventricular outflow obstruction in idiopathic hypereosinophilic syndrome: timely surgical intervention is crucial.

Background: Löffler's endocarditis (LE) is a frequently encountered condition in hypereosinophilic syndrome and is associated with a significant morbidity and mortality rate. Case Summary: A 22-year-old man presented with acute dyspnoea, recurring wheezing, and cough, leading to his hospital admission. Multimodal diagnostic imaging revealed a manifestation of eosinophil-mediated cardiac injury in the thrombus formation stage. Moreover, a mural thrombus and thickened endocardium had caused severe obstruction of the right ventricular outflow tract (RVOT) and complete obliteration of the right ventricular apex, resulting in a significant reduction in right ventricular cardiac output. The patient received a diagnosis of LE and was treated with high-dose corticosteroids and anticoagulants. To alleviate the RVOT obstruction, an emergency surgical intervention was conducted through median sternotomy to the removal of the mural thrombus and resection of the thickened endocardium. Subsequently, eosinophil counts normalized within 1 month. Follow-up imaging examination demonstrated the existence of a residual section of thickened endocardium within the right ventricular free wall. Importantly, no mural thrombus was detected with complete relief of the RVOT obstruction. Notably, a transthoracic echocardiography examination at the 3-month postoperative unveiled a significant regression in right ventricular endomyocardial fibrosis. The patient's condition exhibited tangible improvement, with no adverse events observed. Discussion: Multimodal imaging is essential for the early diagnosis and accurate staging of LE. Timely surgical intervention, combined with corticosteroid therapy, is an effective therapeutic approach in selected patients with LE. This approach is crucial to achieve remission of acute phase symptoms and improve prognosis.

Raoultella ornithinolytica Urinary Tract Infection in a Patient With Triple-Negative Breast Cancer.

Due to the challenges associated with accurately identifying Raoultella ornithinolytica as the causative agent in urinary tract infections (UTIs), coupled with limited guidance on treatment protocols, reports of similar cases still need to be made publicly available because of their increasing emergence. In this article, we present the first documented case of a UTI caused by Raoultella ornithinolytica in a patient with triple-negative breast cancer undergoing neoadjuvant chemotherapy. This case report highlights Raoultella ornithinolytica as an uncommon yet significant pathogen, particularly in immunocompromised patients. Given the bacterium's antibiotic resistance patterns, it emphasizes the importance of prompt, accurate identification methods and tailored treatment strategies, especially in vulnerable populations undergoing chemotherapy.

Treatment Response and Survival with Chemotherapy for Unresectable, Nonmetastatic Cholangiocarcinoma.

Background and objectives: Limited studies have dwelt upon the treatment of unresectable, nonmetastatic cholangiocarcinoma as a separate entity. Hence, the management protocols are not clearly defined for this subgroup of patients. We aimed to analyze patients treated for unresectable, nonmetastatic cholangiocarcinoma. Materials and methods: We analyzed the treatment of patients with unresectable, nonmetastatic cholangiocarcinoma retrospectively. Results: A total of 162 cases of cholangiocarcinoma were reported to our center from 2016 to 2019, out of which 54 were unresectable and nonmetastatic. Thirty patients opted for treatment and were the subjects of this study. Of 30 patients, 24 had hyperbilirubinemia, out of which 10 received chemotherapy after biliary drainage procedure. Out of 30 patients, a total of 16 patients had received chemotherapy, while 14 did not. Gemcitabine/Cisplatin was the first-line chemotherapy administered to 9 patients, whereas 5 received Gemcitabine/Capecitabine and 2 received single-agent gemcitabine. Partial response was documented in 6 patients, and 4 patients had stable disease. The median overall survival was 12.04 months in patients who had received chemotherapy and 6.02 months in those who did not receive chemotherapy (p = 0.005). The median progression-free survival was 6.53 months for patients who had received chemotherapy. The aHR for mortality with chemotherapy compared with no chemotherapy was 0.353 (95% CI: 0.154-0.807). Conclusion: The study data demonstrate that gemcitabine combined with cisplatin- or capecitabine-based chemotherapy prolongs survival in patients with unresectable and nonmetastatic cholangiocarcinoma. In patients with cholangiocarcinoma associated with jaundice, biliary drainage procedure enables giving chemotherapy. Hyperbilirubinemia persisting despite drainage procedures portends poor prognosis and represents an unmet need. How to cite this article: Gupta A, Sahai P, Prasad M, et al.

Impact of a Switch From Ciprofloxacin to Ceftriaxone Prophylaxis on Infectious Complications After Transrectal Ultrasound-Guided Biopsy of the Prostate.

In a 12-year single-center quasi-experimental study, a switch from ciprofloxacin to ceftriaxone prophylaxis for transrectal ultrasound-guided prostate biopsy procedures was associated with a significant reduction in 30-day postprocedure urinary tract infection, urinary tract infection-related hospitalizations, antibiotic prescriptions, and isolation of fluoroquinolone-resistant organisms from urine or blood cultures.

Presentation of Rarely Occurring Inverted Squamous Papilloma of Nasal Cavity: A Case Report.

This report presents a case of a rarely occurring inverted squamous papilloma, which shows papillary proliferation in squamous epithelium. Inverted papillomas (IPs) are benign epithelial growths that occur in the underlying stroma of the nasal cavity and paranasal sinuses. While viral infections, allergies, and chronic sinusitis have all been proposed as potential causes, the pathophysiology of this lesion is still unknown. Most of the time, IP reflects residual disease, yet the recurrence rates are extremely high. A 60-year-old male patient has chief complaints of right-sided nasal congestion and excessive sneezing and discharge from the nose, which cause discomfort to the patient and make him unable to sleep at night. Computed tomography reveals both the enlargement of the osteomeatal complex and soft-tissue density opacification of the right side of the nasal cavity. The only way to diagnose this type of squamous papilloma is through histopathological examination. In this work, we evaluated the histological characteristics of sinonasal IP and presented a case report of an uncommon instance of inverted squamous papilloma of the nasal cavity.

Performance verification and clinical evaluation of the NAP-Fluo Cycler system for detecting five genital tract pathogens based on microfluidic technology.

Introduction: Sexually transmitted infections (STIs) are among the most common infectious diseases worldwide, often leading to coinfections. Timely detection of genital tract pathogens in at-risk populations is crucial for preventing STIs. We evaluated the NAP-Fluo Cycler System, an innovative microfluidic nucleic acid detection platform, for its ability to simultaneously identify Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Ureaplasma urealyticum (UU), Mycoplasma genitalium (MG), and Mycoplasma hominis (MH) in urethral or cervical secretions. Materials and methods: The limits of detection (LODs), repeatability, specificity, and interference resistance of the system were evaluated using standard strains, a panel of 24 pathogens, and seven interferents. We used the system to analyze 302 clinical samples and compared the results with those of five approved commercial reference kits. Results: The system achieved LODs of 500 IFU/mL, 500 CFU/mL, and 500 CCU/mL for CT, NG, and UU/MG/MH, respectively, demonstrating high stability (coefficient of variation <1.1 %), specificity, and resistance to interference. Among 302 clinical samples, 237 tested positive with single, dual, and triple infection rates of 35.6 %, 16.2 %, and 3.0 %, respectively. The reference kits detected 138 positive samples. The concordance rates with commercial reference kits were 100 % for UU, NG, and MH; 94.85 % for CT; and 80.00 % for MG. Conclusions: This system offers a streamlined, rapid, and multiplex detection method that reduces testing time and complexity. Although it performs well with pure strains, it has limitations when using clinical samples of CT and MG, suggesting the need for further refinement before its widespread use in the clinic.

A systematic review and network meta-analysis comparing Rezum with transurethral needle ablation and microwave thermotherapy for the management of enlarged prostate.

Objectives: We aim to compare efficacy and safety of water vapour therapy (Rezum), transurethral needle ablation (TUNA) and transurethral microwave therapy (TUMT) for treating men with moderate to severe benign prostatic hyperplasia (BPH) symptoms. Materials: PubMed/MEDLINE, EMBASE and Cochrane Library were searched from inception to 30 July 2023, followed by reference searching and dual-independent study selection. We analysed only randomized clinical trials. RoB-2, NIH-quality assessment tool and GRADE guidelines were used for quality-of-evidence (QoE) assessment. Relevant prospective studies without a critical risk-of-bias were included. Results: At 12 months, Rezum showed similar efficacy to TUNA and TUMT for improvement in International Prostate Symptoms Score - Rezum versus TUMT: 1.33 points (95% CI: -1.66 to 4.35) favouring TUMT (QoE: Moderate) and Rezum versus TUNA: 0.07 points (95% CI: -3.64 to 3.88) favouring TUNA (QoE: Low). Rezum had similar outcomes to TUNA and TUMT for Maximum Peak-Flow Rate (Qmax): Rezum versus TUMT: 1.05 mL/s (95% CI: -4.88 to 2.82) favouring Rezum (QoE: Low) and Rezum versus TUNA: 0.37 mL/s (95% CI: -4.61 to 4.21) favouring TUNA (QoE: Low). Furthermore, post-void residual volume (PVR) comparisons demonstrated that Rezum was similar, or inferior to other techniques at 12 months - Rezum versus TUMT: 11.20 mL (95% CI: -32.40 to 10.30) favouring TUMT (QoE: Low) and Rezum versus TUNA: 24.10 mL (95% CI: 2.81 to 45.10) favouring TUNA (QoE: Low). Rezum also had a similar surgical retreatment rate with TUMT and TUNA up to 3-years - TUMT versus Rezum RR: 1.21 (95% CI: 0.20 to 15.90) (QoE: Low) and TUNA versus Rezum showed RR: 1.81 (95% CI: 0.2 to 24.60) (QoE: Low). In the first 12 months after treatment, Rezum had a higher rate of serious adverse events (Clavien-Dindo ≥ Grade 3) than TUMT and TUNA. TUMT versus Rezum with RR = 0.53 (95% CI: 0.13 to 3.14) (QoE: Low) and TUNA versus Rezum with RR = 0.38 (95% CI: 0.04 to 3.49) (QoE: Low). Conclusions: Moderate to weak evidence suggests that Rezum is not superior to TUNA and TUMT in all domains studied.

Evaluating the safety of bipolar nephrostomy tract cauterization "BNTC" towards a safe tubeless percutaneous nephrolithotomy: a randomized controlled trial.

To assess the safety and effectiveness of tubed versus tubeless percutaneous nephrolithotomy (PCNL) after tract inspection and bipolar cauterization of the significant bleeders. Patients who were scheduled for PCNL were screened for enrollment in this prospective randomized controlled trial. The patients were randomly assigned to one of two groups; Group 1 received tubeless PCNL with endoscopic inspection of the access tract using bipolar cauterization of the significant bleeders only, while Group 2 had a nephrostomy tube was inserted without tract inspection. We excluded patients with multiple tracts, stone clearance failure, and significant collecting system perforation. We recorded blood loss, hemoglobin drop after 6 h, postoperative analgesia requirements, hospital stay, and the need for angioembolization. A total of 110 patients completed the study. There were no significant differences between the two groups in in terms of demographic characteristics. Likewise, there was no significant difference in the mean decrease in hemoglobin after 6 h and the frequency of blood transfusion. However, the incidence of hematuria within the first 6 h (p = 0.008), postoperative pain scale (p = 0.0001), the rate of analgesia requirement (p = 0.0001) and prolonged hospital stay (p = 0.0001) were significantly higher in Group 2. Only 9 cases of tract screened patients (16% of group 1) required cauterization. Tubeless PCNL with tract inspection and cauterization of bleeders can provide a safer tubeless PCNL with less postoperative pain, analgesia requirement, and same-day discharge.

Trash into Treasure: Nano-coating of Catheter Utilizes Urine to Deprive H2S Against Persister and Rip Biofilm Matrix.

Bacteria-derived hydrogen sulfide (H2S) often contributes to the emergence of antibiotic-recalcitrant bacteria, especially persister (a sub-population of dormant bacteria), thus causing the treatment failure of Catheter-associated urinary tract infection (CAUTI). Here, an H2S harvester nanosystem to prevent the generation of persister bacteria and disrupt the dense biofilm matrix by the self-adaptive ability of shape-morphing is prepared. The nanosystem possesses a core-shell structure that is composed of liquid metal nanoparticle (LM NP), AgNPs, and immobilized urease. The nanosystem decomposes urea contained in urine to generate ammonia for eliminating bacteria-derived H2S. Depending on the oxidative layer of liquid metal, the nanosystem also constitutes a long-lasting reservoir for temporarily storing bacteria-derived H2S, when urease transiently overloads or in the absence of urine in a catheter. Depriving H2S can prevent the emergence of persistent bacteria, enhancing the bacteria-killing efficiency of Ga3+ and Ag+ ions. Even when the biofilm has formed, the urine flow provides heat to trigger shape morphing of the LM NP, tearing the biofilm matrix. Collectively, this strategy can turn trash (urea) into treasure (H2S scavengers and biofilm rippers), and provides a new direction for the antibacterial materials application in the medical field.

Prospective study of urinary incontinence recovery following endoscopic enucleation of the prostate.

OBJECTIVE: To investigate the clinical trajectories and identify risk factors linked to post-enucleation urinary incontinence (UI). PATIENTS AND METHODS: In this prospective study (April 2020 to March 2022) at a single institution, 316 consecutive patients receiving endoscopic enucleation due to benign prostatic enlargement were included. Patient information and perioperative details were collected. Follow-ups, from 1 to 6 months, assessed postoperative UI using International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form and a four-item pad questionnaire, classified per International Continence Society definitions. Logistic regression analysed predictors at 1 week, while generalised estimating equation assessed risk factors from 1 to 3 months postoperatively. RESULTS: Patients with a median prostate volume of 57 mL underwent enucleation, with 22.5% experiencing postoperative UI at 1 week, 5.6% at 3 months, decreasing to 1.9% at 6 months. Multivariable analysis identified age (>80 years), specimen weight (>70 g), en bloc with anteroposterior dissection, and anal tone (Digital Rectal Examination Scoring System score <3) as potential factors influencing UI. Subgroup analysis revealed that specimen weight was associated with both continuous and stress UI. Anal tone was related to both other types and stress UI, while overactive bladder symptoms were associated with urge UI. CONCLUSION: In summary, our study elucidates transient risk factors contributing to temporary post-enucleation UI after prostatectomy. Informed decisions and personalised interventions can effectively alleviate concerns regarding postoperative UI.

A systematic review of the literature on localized gastrointestinal tract amyloidosis: Presentation, management and outcomes.

PURPOSE: Localized gastrointestinal tract amyloidosis is uncommon and little is known regarding this entity. There is no current standard of care for the management of localized amyloidosis. The objective of this study was to evaluate the characteristics, available treatments, outcomes and surveillance of these patients. METHODS: We conducted a systematic review of cases reported in the literature from 1962 to 2021. Patients with gastrointestinal amyloidosis reported in English literature were included in the analysis. We described and summarized the patient's characteristics, treatments, clinical presentations, outcomes and surveillance. RESULTS: The systematic review of reported clinical cases included 62 patients. In these patients, the most common site of amyloid deposition was the stomach (42%). The median age of diagnosis is 64.4 years old; there is a 2:1 prevalence among males (63%) to females (37%); abdominal pain is the most common type of presentation (41%), although patients could also be asymptomatic. There is a high curative rate (100%) with resection alone. Among patients treated with a type of systemic therapy, 80% achieved a complete response. The minority of cases reported a type of surveillance post treatment, and among those 62% pursued serial clinical evaluations alone. CONCLUSION: To our knowledge, this is the first and largest systematic review of the literature in gastrointestinal tract amyloidosis. This is more common among males and seems to have an excellent curative rate (100%) with surgery alone. Systemic therapy is an option for those with non-resectable amyloidomas. Serial clinical evaluations should be part of the standard surveillance care in these patients.

Developing a urinary incontinence primary care pathway: a mixed methods study.

BACKGROUND: While nearly 50% of adult women report at least one episode of urinary incontinence (UI), most never receive treatment. OBJECTIVE: To better integrate primary and specialty UI care, we conducted (i) an environmental scan to assess the availability of key pathway resources in primary care, (ii) interviews with primary care providers to understand barriers to care, and (iii) a pilot UI care pathway intervention. METHODS: Environmental scan: Clinic managers from all primary care clinics within a Midwestern healthcare system were invited to participate in an interview covering the availability of clinic resources. Provider interviews: Primary care providers were invited to participate in an interview covering current practices and perceived barriers to UI care. Pilot UI care pathway: Patients who screened positive for UI were provided resources for first-line behavioral management. Pilot patients completed questionnaires at baseline, 8 weeks, and 6 months. RESULTS: While many clinics had point-of-care urinalysis (17/21, 81%), most did not have a working bladder ultrasound (14/21, 67%) or on-site pelvic floor physical therapy (18/21, 86%). Providers (n = 5) described barriers to completing almost every step of diagnosis and treatment for UI. The most persistent barrier was lack of time. Patients (n = 15) reported several self-treatment strategies including avoiding bladder irritants (7/15, 47%) and performing Kegel exercises (4/15, 27%). Five patients (33%) requested follow-up care. At 6 months, patients reported small improvements in UI symptoms. CONCLUSION: Promising results from a novel UI care pathway pilot indicate that streamlining UI care may assist primary care providers in the first-line treatment of UI.

Although the majority of women will experience urine leakage at some point during their lives, most will never receive treatment. To better understand this discrepancy, we embarked on a multimodal investigation into the barriers to care and trialed a new treatment pathway in the primary care setting within a large academic medical system in the Midwest. Speaking with the clinic managers from 21 primary care clinics, we determined that many clinics lacked the tools to perform the steps outlined in the professional society guidelines for urinary incontinence diagnosis. Additionally, there was limited access to pelvic floor physical therapy, a proven treatment strategy. Interviews with five primary care providers revealed barriers, most notably lack of time during clinic visits, to almost every step of diagnosis and treatment. Finally, we trialed a care pathway for primary care providers to make it easier to provide patients with self-management education or to refer them to specialist care. Fifteen patients participated in a pilot study, about half reported trying self-management, and about 1/3 requested follow-up care. Streamlining urinary incontinence care at the primary care level may alleviate some of the barriers to patients receiving care.

Risks of Post-Endoscopic Retrograde Cholangiopancreatography Pancreatitis After Liver Transplantation.

Biliary complications are common after liver transplantation (LT). Endoscopic retrograde cholangiopancreatography (ERCP) is the preferred method to treat biliary complications. Nevertheless, ERCP is not without complications and may have a greater complication rate in the LT population. Knowledge of the prevalence, severity, and possible risk factors for post-ERCP pancreatitis (PEP) in LT recipients is limited. Therefore, this study aims to determine the incidence and severity of PEP and identify potential risk factors in LT recipients. This retrospective cohort included patients ≥18 years who underwent ≥1 ERCP procedures after LT between January 2010 and October 2021. Two hundred thirty-two patients were included, who underwent 260 LTs and 1125 ERCPs. PEP occurred after 23 ERCP procedures (2%) with subsequent mortality in three (13%). Multivariate logistic regression identified wire cannulation of the pancreatic duct as a significant risk factor for PEP (OR, 3.21). The complication rate of PEP after LT in this study was shown to be low and is lower compared to patients without a history of LT. Nevertheless, the mortality rate of this group of patients was notably higher.

Stress-induced impairment of parasympathetic NO-mediated inhibition of sympathetic vasoconstriction in submucosal arteriole of rat rectum.

In the gastrointestinal tract, nitrergic inhibition of the arteriolar contractility has not been demonstrated. Here, we explored whether neurally-released nitric oxide (NO) inhibits sympathetic vasoconstrictions in the rat rectal arterioles. Changes in sympathetic vasoconstrictions and their nitrergic modulation in rats exposed to water avoidance stress (WAS, 10 days, 1 h per day) were also examined. In rectal submucosal preparations, changes in arteriolar diameter were monitored using video microscopy. In control or sham-treated rats, electrical field stimulation (EFS)-induced sympathetic vasoconstrictions were increased by the neuronal nitric oxide synthase (nNOS) inhibitor L-NPA (1 µM) and diminished by the cyclic guanosine monophosphate-specific phosphodiesterase 5 (PDE5) inhibitor tadalafil (10 nM). In phenylephrine-constricted, guanethidine-treated arterioles, EFS-induced vasodilatations were inhibited by the calcitonin gene-related peptide (CGRP) receptor antagonist BIBN-4096 (1 µM) but not L-NPA. Perivascular nNOS-immunoreactive nitrergic fibres co-expressing the parasympathetic marker vesicular acetylcholine transporter (VAChT) were intermingled with tyrosine hydroxylase (TH)-immunoreactive sympathetic fibres expressing soluble guanylate cyclase (sGC), a receptor for NO. In WAS rats in which augmented sympathetic vasoconstrictions were developed, L-NPA failed to further increase the vasoconstrictions, while tadalafil-induced inhibition of the vasoconstrictions was attenuated. Phenylephrine- or α,ß-methylene ATP-induced vasoconstrictions and acetylcholine-induced vasodilatations were unaltered by WAS. Thus, in arterioles of the rat rectal submucosa, NO released from parasympathetic nerves appears to inhibit sympathetic vasoconstrictions presumably by reducing sympathetic transmitter release. In WAS rats, sympathetic vasoconstrictions are augmented at least partly due to the diminished pre-junctional nitrergic inhibition of transmitter release without changing α-adrenoceptor or P2X-purinoctor mediated vasoconstriction and endothelium-dependent vasodilatation.

Neighborhood Resources and Health Outcomes Among Stroke Survivors in a Population-Based Cohort.

BACKGROUND: Stroke survivors believe neighborhood resources such as community centers are beneficial; however, little is known about the influence of these resources on stroke outcomes. We evaluated whether residing in neighborhoods with greater resource density is associated with favorable post-stroke outcomes. METHODS AND RESULTS: We included Mexican American and non-Hispanic White stroke survivors from the Brain Attack Surveillance in Corpus Christi project (2009-2019). The exposure was density of neighborhood resources (eg, community centers, restaurants, stores) within a residential census tract at stroke onset. Outcomes included time to death and recurrence, and at 3 months following stroke: disability (activities of daily living/instrumental activities of daily living), cognition (Modified Mini-Mental State Exam), depression (Patient Health Questionnaire-8), and quality of life (abbreviated Stroke-Specific Quality of Life scale). We fit multivariable Cox regression and mixed linear models. We considered interactions with stroke severity, ethnicity, and sex. Among 1786 stroke survivors, median age was 64 years (interquartile range, 56-73), 55% men, and 62% Mexican American. Resource density was not associated with death, recurrence, or depression. Greater resource density (75th versus 25th percentile) was associated with more favorable cognition (Modified Mini-Mental State Exam mean difference=0.838, 95% CI=0.092, 1.584) and among moderate-severe stroke survivors, with more favorable functioning (activities of daily living/instrumental activities of daily living=-0.156 [95% CI, -0.284 to 0.027]) and quality of life (abbreviated Stroke-Specific Quality of Life scale=0.194 [95% CI, 0.029-0.359]). CONCLUSIONS: We observed associations between greater resource density and cognition overall and with functioning and quality of life among moderate-severe stroke survivors. Further research is needed to confirm these findings and determine if neighborhood resources may be a tool for recovery.
