Minimally invasive surgical therapies for benign prostatic hyperplasia in the geriatric population: A systematic review.

BACKGROUND: Geriatric patients, prone to adverse events (AEs) and low compliance with drugs, may benefit from minimally invasive surgical therapies (MISTs) for managing benign prostatic hyperplasia (BPH). We evaluated the efficacy, safety, and procedural characteristics of MISTs in geriatric patients with BPH. METHODS: PubMed/MEDLINE database was systematically searched for relevant articles through October 1, 2023. Eligible studies focused on geriatric patients (≥65 years) with BPH who were treated with MISTs and evaluated follow-up surgical, micturition, and/or sexual outcomes. Studies were included if there was separate reporting for age subgroups ≥65 years, or if the mean age minus standard deviation was ≥65 years, or if the first quartile was ≥65 years. RESULTS: Out of 292 screened studies, 32 (N = 3972 patients) met inclusion criteria and assessed prostatic artery embolization (PAE), Rezum, GreenLight, holmium laser enucleation of the prostate (HoLEP), thulium laser enucleation of the prostate (ThuLEP), diode laser enucleation of the prostate (DiLEP), and Aquablation. Except for Rezum, all MISTs required a planned overnight stay. While PAE and Rezum could be performed under local anesthesia, the other MISTs needed general or spinal anesthesia. Postoperative catheterization duration was longest for PAE (median 14 days) and Rezum (21 days) and shortest for GreenLight (1.9 days). At 12 months postoperatively, all MISTs exhibited significant percent changes in International Prostate Symptom Score (median -69.9%) and quality of life (median -72.5%). Clavien-Dindo Grade 1 AEs ranged widely, with PAE (5.8%-36.8%), Rezum (0%-62.1%), and GreenLight (0%-67.6%) having the largest range, and HoLEP (0%-9.5%), ThuLEP (2%-6.9%), and DiLEP (5%-17.5%) having the smallest. PAE, Rezum, DiLEP, and Aquablation reported no significant changes in the International Index of Erectile Function. CONCLUSIONS: Although all the MISTs reviewed in this study effectively treat BPH in geriatric patients, differences in procedural characteristics and safety profiles across MISTs were considerable. Physicians should use shared decision-making processes, considering risks and patient characteristics, when choosing a suitable treatment option for their patients.

Initial safety outcomes for the Rigicon Infla10® inflatable penile prosthesis.

OBJECTIVE: To analyse data from patient information forms (PIFs) submitted to the manufacturer of a new three-piece inflatable penile prosthesis (IPP), the Rigicon Infla10®, to summarize early outcomes. METHODS: A retrospective review of PIFs from 319 patients implanted with the IPP between 6 January 2019 and 31 December 2021 was performed to assess device durability and rates of reoperation for infection, mechanical failure or medical reasons. RESULTS: The mean ± sd (range) follow-up was 21.2 ± 11 (5-36) months and the mean ± sd patient age was 58.5 ± 8.7 years. Of the total, 4.4% of devices required removal or revision. Complications included mechanical failure (2.5%) and component migration (0.7%). No infections were observed in this series. One patient (0.4%) required revision for inadequate straightening of Peyronie's disease. Three patients (0.9%) requested device removal because of dissatisfaction. A total of 95.6% of the Rigicon Infla10 devices were free from explant or revision 21 months after the original implant date. Kaplan-Meier analysis showed the rates of cumulative survival of the device at 12, 24, 36 months were 95.6%, 94.7% and 93.7%, respectively. CONCLUSIONS: The vast majority of the early Rigicon Infla10 IPPs implanted prior to January 2022 were included in this retrospective analysis of volunteered PIFs. These early results demonstrate initial durability from reoperation equivalent to that of other contemporary devices.

Nutritional counselling in adults promoting adherence to the Mediterranean diet as adjuvant in the treatment of major depressive disorder (INDEPT): a randomized open controlled trial study protocol.

BACKGROUND: Major Depressive Disorder (MDD) is a leading cause of disability worldwide. Approximately one-third of patients with MDD do not respond to treatment, and often exhibit elevated inflammation biomarkers, which are associated with worse prognosis. Previous research has linked healthier dietary patterns, such as the Mediterranean Diet (MedDiet), with a lower risk of MDD and symptoms of depression, potentially due to their anti-inflammatory properties. The aim of this study is to evaluate the effectiveness of a nutritional counselling intervention promoting MedDiet to alleviate symptoms of depression in adults recently diagnosed with MDD and presenting with elevated inflammation biomarkers. METHODS: This study is a randomized controlled trial (RCT) that will recruit adults from outpatient clinics, between the ages of 18 and 70 years who have been diagnosed with MDD and are currently receiving treatment with the first prescribed antidepressant, and who exhibit elevated inflammation biomarkers (interleukin-6 and/or C-reactive protein). The control group will receive treatment-as-usual (TAU) only. The primary outcome of the study will be the change in symptoms of depression, as measured by the Beck Depression Inventory 2 (BDI-II), after 12 weeks of intervention. Data analysis will follow an intention-to-treat approach. Secondary outcomes will include changes in inflammation biomarkers, quality of life, adherence to the MedDiet, and cost-effectiveness of nutritional counselling. All outcomes will be assessed at baseline, after the 12-week intervention, and at 6- and 12-months post-baseline. DISCUSSION: This study will be the first RCT to evaluate the effect of a nutritional intervention with anti-inflammatory properties, as an adjuvant in the treatment of MDD, in individuals diagnosed with MDD and elevated inflammation biomarkers. The results of this study may contribute to the development of more effective and personalized interventions for MDD patients with elevated inflammation biomarkers.

Cross-sectional and comparative analysis of videos on erectile dysfunction treatment on YouTube and TikTok.

The aim of this study was to evaluate the quality of information regarding erectile dysfunction (ED) treatment on YouTube and TikTok. The term "erectile dysfunction" was searched on YouTube and TikTok in July 2021. The first 50 videos on each platform that met inclusion were included. Videos were sorted as reliable or unreliable based on accuracy of video content. Quality of information was evaluated using Patient Education Materials Assessment Tool (PEMAT) and 5-point modified DISCERN. TikTok videos were shorter (0.4 minutes vs. 5.2 minutes, p < 0.001) and had more likes (2294 vs. 1000, p = 0.005), views per month (17,281 vs. 3521, p < 0.001) and subscribers/followers (97,500 vs. 23,000, p = 0.016) than YouTube videos. TikTok videos were less reliable than YouTube videos (TikTok 5/50 [10%] vs. YouTube 21/50 [42%], p < 0.001). YouTube mentioned more about phosphodiesterase type 5 inhibitors (32% vs. 10%, p = 0.007), while TikTok mentioned more about alternative supplements (36% vs. 4%, p < 0.001). YouTube had a higher DISCERN (1.99 vs. 0.98, p < 0.001) and PEMAT actionability scores (64.2% vs. 54.0%, p = 0.039) when compared to TikTok. YouTube videos were of higher quality than TikTok videos. Nevertheless, YouTube had a considerable amount of unreliable information. We recommend a collaborative effort from the medical community to improve information regarding ED treatment on YouTube and TikTok.

Rates of False-Negative Screening in Prostate Specific Antigen Secondary to 5-Alpha Reductase Inhibitor Usage: A Quality-Improvement Initiative.

PURPOSE: Patients often take 5-alpha reductase inhibitors (5-ARIs) for the management of benign prostatic hyperplasia. However, 5-ARIs can decrease prostate specific antigen (PSA) by approximately half and therefore may lead to false negative PSA tests. We investigated false-screening rates in men on 5-ARIs undergoing PSA testing and whether ordering physicians noticed false negative findings. MATERIALS AND METHODS: A single institution, retrospective study was conducted on patients with a PSA value documented between 2014 and 2017. Patient demographics, PSA results, 5-ARI usage, and providing clinician characteristics were collected. Published normal PSA values were used to determine PSA test positivity; values for those on 5-ARIs were doubled. RESULTS: A total of 29,131 men were included. 1,654 (5.7%) were prescribed 5-ARIs at least 12 months prior to PSA evaluation. 118 men (7.1%) had a value that would be positive if corrected for 5-ARI usage, 33 (27.9%) of which had no indication that the provider had noted this. There was no effect on rates of false negative values if the PSA was ordered by a different provider than the one who prescribed the 5-ARI (p = 0.837). However, if the provider who ordered the PSA test was an urologist, the likelihood that a false negative value would be identified was lower (p=0.001). CONCLUSIONS: More than a quarter of men with false negative tests were missed. This occurred more often when the ordering provider was not an urologist. An educational opportunity exists to improve the quality of PSA testing by preventing false negative tests.

Multicenter Investigation of Fungal Infections of Inflatable Penile Prostheses.

BACKGROUND: Fungal infections of inflatable penile prostheses (IPPs) are inadequately understood in the literature. AIM: To review a multi-institution database of IPP infections to examine for common patient and surgical factors related to IPP fungal infections. METHODS: This is a retrospective Institutional Review Board-approved analysis of 217 patients at 26 institutions who underwent salvage or device explant between 2001 and 2018. Patient data were compiled after an extensive record review. OUTCOMES: 26 patients (12%) with fungal infections were identified. RESULTS: 23 of 26 patients (83%) with a fungal IPP infection were either diabetic or overweight. 15 patients had undergone primary IPP implantation, and the other 11 had previously undergone an average of 1.7 IPP-related surgeries (range 1-3; median 2). The average age at implantation was 63 years (range 31-92; median 63). 18 of the 26 patients with fungal infection had diabetes (69%), with a mean hemoglobin A1c (HbA1c) value of 8.4 (range 5.8-13.3; median 7.5). Twenty-two patients (85%) were overweight or obese. The mean body mass index for all patients was 30.1 kg/m2 (range 23.7-45 kg/m2; median 28.4 kg/m2), and that for diabetic patients was 30.8 kg/m2 (range 24.1-45 kg/m2, median 29.7 kg/m2). Ninety-one percent of implants were placed with intravenous antibiotics, consistent with current American Urological Association guidelines: an aminoglycoside plus first- or second-generation cephalosporin or vancomycin or ampicillin/sulbactam or piperacillin/tazobactam. 65% (17 of 26) of infected IPPs had only fungal growth in culture. No patient had concomitant immunosuppressive disease or recent antibiotic exposure before IPP implantation. CLINICAL IMPLICATIONS: More than two-thirds of the fungal infections occurred in diabetic patients and 85% occurred in overweight or obese patients, suggesting that antifungal prophylaxis may be appropriate in these patients. STRENGTHS & LIMITATIONS: This is the largest series of fungal infections reported to date in the penile prosthesis literature. The overall number of such cases, however, remains small. CONCLUSION: Fungal infections represent 12% of all penile prosthesis infections in our series and were seen mostly in diabetic or overweight patients, who may benefit from antifungal prophylaxis.

Multicenter Investigation of the Micro-Organisms Involved in Penile Prosthesis Infection: An Analysis of the Efficacy of the AUA and EAU Guidelines for Penile Prosthesis Prophylaxis.

INTRODUCTION: Penile prosthesis infections remain challenging despite advancements in surgical technique, device improvements, and adoption of antibiotic prophylaxis guidelines. AIM: To investigate penile prosthesis infection microbiology to consider which changes in practice could decrease infection rates, to evaluate current antibiotic prophylaxis guidelines, and to develop a proposed algorithm for penile prosthesis infections. METHODS: This retrospective institutional review board-exempt multi-institutional study from 25 centers reviewed intraoperative cultures obtained at explantation or Mulcahy salvage of infected three-piece inflatable penile prostheses (IPPs). Antibiotic usage was recorded at implantation, admission for infection, and explantation or salvage surgery. Cultures were obtained from purulent material in the implant space and from the biofilm on the device. MAIN OUTCOME MEASURES: Intraoperative culture data from infected IPPs. RESULTS: Two hundred twenty-seven intraoperative cultures (2002-2016) were obtained at salvage or explantation. No culture growth occurred in 33% of cases and gram-positive and gram-negative organisms were found in 73% and 39% of positive cultures, respectively. Candida species (11.1%), anaerobes (10.5%) and methicillin-resistant Staphylococcus aureus (9.2%) constituted nearly one third of 153 positive cultures. Multi-organism infections occurred in 25% of positive cultures. Antibiotic regimens at initial implantation were generally consistent with American Urological Association (AUA) and European Association of Urology (EAU) guidelines. However, the micro-organisms identified in this study were covered by these guidelines in only 62% to 86% of cases. Antibiotic selection at admissions for infection and salvage or explantation varied widely compared with those at IPP implantation. CONCLUSION: This study documents a high incidence of anaerobic, Candida, and methicillin-resistant S aureus infections. In addition, approximately one third of infected penile prosthesis cases had negative cultures. Micro-organisms identified in this study were not covered by the AUA and EAU antibiotic guidelines in at least 14% to 38% of cases. These findings suggest broadening antibiotic prophylaxis guidelines and creating a management algorithm for IPP infections might lower infection rates and improve salvage success.

Couples' discontinuation of fertility treatments: a longitudinal study on demographic, biomedical, and psychosocial risk factors.

PURPOSE: This study aims to explore the role of infertility-psychosocial variables on treatment discontinuation after controlling for demographic and biomedical variables in couples seeking reimbursed fertility treatment. METHODS: A prospective study was conducted in 139 couples seeking fertility treatment. Between February 2010 and March 2011, participants completed measures of anxiety (STAI-State), depression (BDI-II), infertility-stress (FPI), and infertility coping strategies (COMPI-CSS). Medical data related to diagnosis, treatment, and discontinuation were collected in December 2013. A multiple logistic regression was performed to identify the predictors of discontinuation. RESULTS: The discontinuation rate was 29.5%. Female education level, engagement in ART procedures, and female causation decreased the likelihood of treatment discontinuation, whereas female age and depression increased the likelihood of discontinuation. Female depression was the strongest predictor in this model. The model correctly identified 75.5% of cases. CONCLUSIONS: Female age and female depression are associated with a higher likelihood of treatment discontinuation in couples seeking treatment. Reproductive health professionals should therefore inform couples about the link between the fertility treatment discontinuation and both female age and female depression. Couples in which female partners present clinically relevant depression should be referred to a mental health professional to prevent premature abandonment of fertility treatments and thus increase success rates.

Intraperitoneal Urinary Bladder Perforation with Pneumoperitoneum in Association with Indwelling Foley Catheter Diagnosed in Emergency Department.

BACKGROUND: Indwelling Foley catheter is a rare cause of urinary bladder perforation, a serious injury with high mortality that demands accurate and prompt diagnosis. While the gold standard for diagnosis of bladder injury is computed tomography (CT) cystography, few bladder ruptures associated with Foley catheter have been reported to be diagnosed in the emergency department (ED). CASE REPORT: An 83-year-old man with indwelling Foley catheter presented to the ED for hematuria and altered mental status. He was diagnosed to have intraperitoneal rupture of the urinary bladder in the ED using abdominal and pelvic CT without contrast, which demonstrated bladder wall discontinuity, intraperitoneal free fluid, and pneumoperitoneum. The patient was treated successfully with medical management and bladder drainage. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: To our knowledge, this is the first report of intraperitoneal urinary bladder perforation associated with Foley catheter diagnosed in the ED by CT without contrast. Pneumoperitoneum found in this case was a clue to the diagnosis and is a benign finding that does not necessitate urgent surgical intervention. The early and accurate diagnosis in this case allowed for effective management with good clinical outcome. The use of indwelling Foley catheter has a high prevalence, especially in long-term care facility residents, who are frequent visitors in the ED. Therefore, emergency physicians and radiologists should be familiar with the presentation and imaging findings of this potential injury associated with Foley catheters.

Effects of life events on infertility diagnosis: comparison with presumably fertile men and women.

OBJECTIVE: To compare the occurrence and degree of stress attributed to life events during childhood/adolescence and adulthood between individuals diagnosed with infertility and presumably fertile individuals, and to examine the effect of life events occurrence and stress levels on an infertility diagnosis. BACKGROUND: Although stress has been explored as a consequence of the experience of infertility, its role as a predictor of this disease still lacks research, particularly regarding the use of adequate control groups composed of non-parents. METHODS: The final sample had 151 infertile subjects (74 males and 77 females) and 225 presumably fertile participants (95 males and 130 females), who completed a questionnaire indicating occurrence (y/n) and degree of stress of life events (1-5) during childhood/adolescence and adulthood. RESULTS: Significant differences regarding occurrence were found in seven stressful life events in men and in nine events in women, with infertile groups presenting higher occurrence than presumably fertile groups. Eleven stressful life events were rated differently by men and women regarding the degree of stress, with group significant differences observed in both directions. While most events were rated as more stressful by infertile men, infertile women reported less stress resulting from these events than presumably fertile women. After controlling for age, the degree of stress induced by life events in childhood/adolescence and adulthood were not significant predictors of infertility diagnosis, for both men and women. CONCLUSION: The amount of stress associated with earlier or concurrent life events does not seem to be related with infertility. Further prospective research is needed to validate these findings.

Pudendal nerve block decreases narcotic requirements and time spent in post-anesthesia care units in patients undergoing primary inflatable penile prosthesis implantation.

Efforts to minimize narcotic usage following inflatable penile prosthesis (IPP) implantation are vital, considering the current opioid epidemic in the United States. We aimed to determine whether pudendal nerve block (PNB) utilization in a multiethnic population undergoing primary IPP implantation can decrease rates of post-operative opiate usage. A single-institution, retrospective study was conducted on patients who underwent primary IPP implantation between December 2015 and June 2022. PNB usage and intra- and post-operative outcomes were analyzed using multivariate binary logistic regression. 449 patients were included, with 373 (83.1%) in the PNB group. Median time (minutes) spent in the post-anesthesia care unit (PACU) (1499 [119-198] vs. 235 [169-322], p < 0.001) was significantly lower in the PNB group. There were no significant differences in intra-operative and PACU morphine milligram equivalents or post-operative safety outcomes between groups. However, fewer patients in the PNB group called for pain medications post-operatively (10.2% vs 19.7%, p = 0.019). Multivariate analysis revealed a significantly decreased operative time (B -6.23; 95%CI -11.28, -1.17; p = 0.016) and decreased time in recovery (B: -81.62; 95%CI: -106.49, -56.76, p < 0.001) in the PNB group. PNB decreases post-operative opioid analgesic requirements and time spent in PACU in patients undergoing a primary IPP implantation and thus may represent an attractive, non-opioid adjunct.

Practical management of disease-related manifestations and drug toxicities in patients with multiple myeloma.

Multiple myeloma (MM) is a very heterogeneous disease with multiple symptoms and clinical manifestations. MM affects mainly elderly patients and is difficult to manage in the presence of comorbidities, polypharmacy, frailty and adverse events of disease-targeted drugs. The rapid changes in MM treatment resulting from constant innovations in this area, together with the introduction of numerous new drugs with distinct mechanisms of action and toxicity profiles, have led to an increased complexity in the therapeutic decision-making and patient management processes. The prolonged exposure to novel agents, sometimes in combination with conventional therapies, makes this management even more challenging. A careful balance between treatment efficacy and its tolerability should be considered for every patient. During treatment, a close monitoring of comorbidities, disease-related manifestations and treatment side effects is recommended, as well as a proactive approach, with reinforcement of information and patient awareness for the early recognition of adverse events, allowing prompt therapeutic adjustments. In this review, we discuss various issues that must be considered in the treatment of MM patients, while giving practical guidance for monitoring, prevention and management of myeloma-related manifestations and treatment-related toxicities.

Molecular study of congenital erythrocytosis in 70 unrelated patients revealed a potential causal mutation in less than half of the cases (Where is/are the missing gene(s)?).

INTRODUCTION: Congenital erythrocytosis can be classified as primary, when the defect is intrinsic to the RBC progenitors and independent of the serum erythropoietin (Epo) concentration, or secondary, when the erythrocytosis is the result of an upregulation of Epo production. Primary erythrocytosis is associated with mutations in the EPOR gene, secondary CE can de due to mutations that stabilize the hemoglobin in the oxygenated form or to mutations in the genes that control the transcriptional activation of the EPO gene - VHL, EGLN1, EPAS1. Chuvash polycythemia, caused by mutations in VHL gene, shares features of both primary and secondary erythrocytosis, with increased Epo production but also hypersensitivity of progenitors to Epo. MATERIAL AND METHODS: With the main objective of describing the etiology and molecular basis of CE, we have studied 70 consecutive unrelated patients presenting with idiopathic erythrocytosis from our hematology clinic or referred from other centers. According to a study algorithm, we have sequenced all the genes described as associated with CE. RESULTS AND DISCUSSION: Erythrocytosis molecular etiology was identify in 25 (36%) of the 70 subjects. High-affinity Hb variants were the most common cause, present in 20% of the cases. New mutations were identified in the JAK2, EPOR, VHL, and EGLN1 genes. CONCLUSIONS: High-affinity hemoglobin variants are a very rare cause of secondary CE, but it seems likely that their incidence may be underestimated. Our experience shows that in erythrocytosis with a dominant inheritance and normal or inappropriate high Epo levels, the HBB and HBA genes should be the first to be studied. In spite of the seven genes known to be involved in CE, the majority of the cases have unknown etiology.

Intraoperative use of vancomycin paste during penile prosthesis placement: initial outcomes.

Penile prosthesis implantation is a safe and effective treatment option in the management of erectile dysfunction, associated with high satisfaction and low complication rates. Infection is a rare complication (0.5-3%), but devastating for the patient and surgeon when it occurs. Adapting from other surgical disciplines, we have utilized vancomycin paste to provide prolonged focal antibiotic exposure around the penile prosthesis pump, a site prone to infection. The aim of this study is to determine the safety and efficacy of intraoperative vancomycin paste with regards to infection prevention during penile prosthesis placement. This is a multi-institutional nonrandomized retrospective IRB-approved study comparing patients who underwent placement of a primary inflatable penile prosthesis with intraoperative vancomycin paste to those without. Primary outcomes included pump fibrosis, infection, erosion, hematoma, and complete device malfunction. From April 2019 to October 2019, two surgeons utilized vancomycin paste intraoperatively during virginal penile prosthesis surgery on 90 patients, whose mean age was 60 years. These patients were compared to an historical control group that included 166 patients, also with a mean age of 60 years, who underwent the same penile prosthesis surgery between 2014 and 2017 without the paste. Among the intervention group, the overall complication rate was 1.1%, due to a scrotal hematoma. Ultimately, there was no statistically significant difference in infection rate (0% in both groups) or overall complication rate (1.1% in the intervention group compared to 1.2% in the control group). The use of vancomycin paste appears to be safe, however future prospective studies are needed to determine its efficacy in infection prevention.

Linguistic and cultural adaptation of the EARP Questionnaire to European Portuguese.

OBJECTIVE: This study aims at the linguistic and cultural adaptation of the Early ARthritis for Psoriatic Patients (EARP) questionnaire into European Portuguese, for psoriatic patients attending dermatology medical examination. METHODS: Firstly, we performed a process of translation and back-translation of the English version of the EARP Questionnaire to European Portuguese, with interim and final harmonization. The resulting Portuguese version was approved by the EARP original author. Secondly, individual interviews were conducted to complete the linguistic and cultural adaptation of the initial translated Portuguese version, with the think-aloud and probe methods. At this stage, we conducted eight interviews, four with rheumatology and dermatology doctors (experts), and four with patients with psoriasis and psoriatic arthritis. Finally, the version resulting from the adaptation process was back-translated from Portuguese to English. RESULTS: Our results showed that EARP Questionnaire's items are easy to understand and do not raise comprehension concerns in experts or patients. Our findings suggested that items demanding health literacy from patients and that do not include a precise cue to signal the inflammatory nature of the joint pain may lead to confusion while answering, potentially leading to the patient's need for assistance. CONCLUSION: The Portuguese version of the EARP Questionnaire demonstrated adequate comprehension properties. Our findings support the use of this measure in clinical practice and future research, however, a validation study with Portuguese patients is needed.

Usefulness of serum C-reactive protein and calprotectin for the early detection of colorectal anastomotic leakage: A prospective observational study.

BACKGROUND: Colorectal anastomotic leakage (CAL) is one of the most dreaded complications after colorectal surgery, with an incidence that can be as high as 27%. This event is associated with increased morbidity and mortality; therefore, its early diagnosis is crucial to reduce clinical consequences and costs. Some biomarkers have been suggested as laboratory tools for the diagnosis of CAL. AIM: To assess the usefulness of plasma C-reactive protein (CRP) and calprotectin (CLP) as early predictors of CAL. METHODS: A prospective monocentric observational study was conducted including patients who underwent colorectal resection with anastomosis, from March 2017 to August 2019. Patients were divided into three groups: G1 - no complications; G2 - complications not related to CAL; and G3 - CAL. Five biomarkers were measured and analyzed in the first 5 postoperative days (PODs), namely white blood cell (WBC) count, eosinophil cell count (ECC), CRP, CLP, and procalcitonin (PCT). Clinical criteria, such as abdominal pain and clinical condition, were also assessed. The correlation between biomarkers and CAL was evaluated. Receiver operating characteristic (ROC) curve analysis was used to compare the accuracy of these biomarkers as predictors of CAL, and the area under the ROC curve (AUROC), specificity, sensitivity, positive predictive value, and negative predictive value (NPV) during this period were estimated. RESULTS: In total, 25 of 396 patients developed CAL (6.3%), and the mean time for this diagnosis was 9.0 ± 6.8 d. Some operative characteristics, such as surgical approach, blood loss, intraoperative complications, and duration of the procedure, were notably related to the development of CAL. The length of hospital stay was markedly higher in the group that developed CAL compared with the group with complications other than CAL and the group with no complications (median of 21 d vs 13 d and 7 d respectively; P < 0.001). For abdominal pain, the best predictive performance was on POD4 and POD5, with the largest AUROC of 0.84 on POD4. Worsening of the clinical condition was associated with the diagnosis of CAL, presenting a higher predictive effect on POD5, with an AUROC of 0.9. WBC and ECC showed better predictive effects on POD5 (AUROC = 0.62 and 0.7, respectively). Those markers also presented a high NPV (94%-98%). PCT had the best predictive effect on POD5 (AUROC = 0.61), although it presented low accuracy. However, this biomarker revealed a high NPV on POD3, POD4, and POD5 (96%, 95%, and 96%, respectively). The mean CRP value on POD5 was significantly higher in the group that developed CAL compared with the group without complications (195.5 ± 139.9 mg/L vs 59.5 ± 43.4 mg/L; P < 0.00001). On POD5, CRP had a NPV of 98%. The mean CLP value on POD3 was significantly higher in G3 compared with G1 (5.26 ± 3.58 µg/mL vs 11.52 ± 6.81 µg/mL; P < 0.00005). On POD3, the combination of CLP and CRP values showed a high diagnostic accuracy (AUROC = 0.82), providing a 5.2 d reduction in the time to CAL diagnosis. CONCLUSION: CRP and CLP are moderate predictors of CAL. However, the combination of these biomarkers presents an increased diagnostic accuracy, potentially decreasing the time to CAL diagnosis.

Development of a warning score for early detection of colorectal anastomotic leakage: Hype or hope?

BACKGROUND: Colorectal anastomotic leakage (CAL), a severe postoperative complication, is associated with high morbidity, hospital readmission, and overall healthcare costs. Early detection of CAL remains a challenge in clinical practice. However, some decision models have been developed to increase the diagnostic accuracy of this event. AIM: To develop a score based on easily accessible variables to detect CAL early. METHODS: Based on the least absolute shrinkage and selection operator method, a predictive classification system was developed [Early ColoRectAL Leakage (E-CRALL) score] from a prospective observational, single center cohort, carried out in a colorectal division from a non-academic hospital. The score performance and CAL threshold from postoperative day (POD) 3 to POD5 were estimated. Based on a precise analytical decision model, the standard clinical practice was compared with the E-CRALL adoption on POD3, POD4, or POD5. A cost-minimization analysis was conducted, on the assumption that all alternatives delivered similar health-related effects. RESULTS: In this study, 396 patients who underwent colorectal resection surgery with anastomosis, and 6.3% (n = 25) developed CAL. Most of the patients who developed CAL (n = 23; 92%) were diagnosed during the first hospital admission, with a median time of diagnosis of 9.0 ± 6.8 d. From POD3 to POD5, the area under the receiver operating characteristic curve of the E-CRALL score was 0.82, 0.84, and 0.95, respectively. On POD5, if a threshold of 8.29 was chosen, 87.4% of anastomotic failures were identified with E-CRALL adoption. Additionally, score usage could anticipate CAL diagnosis in an average of 5.2 d and 4.1 d, if used on POD3 and POD5, respectively. Regardless of score adoption, episode comprehensive costs were markedly greater (up to four times) in patients who developed CAL in comparison with patients who did not develop CAL. Nonetheless, the use of the E-CRALL warning score was associated with cost savings of €421442.20, with most (92.9%) of the savings from patients who did not develop CAL. CONCLUSION: The E-CRALL score is an accessible tool to predict CAL at an early timepoint. Additionally, E-CRALL can reduce overall healthcare costs, mainly in the reduction of hospital costs, independent of whether a patient developed CAL.

An Update on the Outcomes of Patients Treated with Urolift for Benign Prostatic Hyperplasia.

Benign prostatic hyperplasia (BPH) is a ubiquitous urologic disease affecting aging men. Patients often experience bothersome lower urinary tract symptoms (LUTS) that warrant urologic evaluation and management. Routinely, patients are initially treated with medical therapies with the goal of both relaxing the bladder neck and shrinking the prostate in order to relieve obstruction secondary to prostatic enlargement. Transurethral resection of the prostate (TURP) serves as a first-line surgical intervention in those who fail medical therapy. Recently, novel minimally invasive surgical techniques for BPH management have emerged. Of these, prostatic urethral lift (PUL or Urolift) has gained attention given its presumed effectiveness and minimal risk of sexual side effects when compared to the standard TURP. The purpose of this review is to describe past and current trends in the implementation of PUL for BPH and to highlight important outcomes.

CBmeter study: protocol for assessing the predictive value of peripheral chemoreceptor overactivation for metabolic diseases.

INTRODUCTION: Early screening of metabolic diseases is crucial since continued undiagnostic places an ever-increasing burden on healthcare systems. Recent studies suggest a link between overactivated carotid bodies (CB) and the genesis of type 2 diabetes mellitus. The non-invasive assessment of CB activity by measuring ventilatory, cardiac and metabolic responses to challenge tests may have predictive value for metabolic diseases; however, there are no commercially available devices that assess CB activity. The findings of the CBmeter study will clarify the role of the CBs in the genesis of-metabolic diseases and guide the development of new therapeutic approaches for early intervention in metabolic disturbances. Results may also contribute to patient classification and stratification for future CB modulatory interventions. METHODS: This is a non-randomised, multicentric, controlled clinical study. Forty participants (20 control and 20 diabetics) will be recruited from secondary and primary healthcare settings. The primary objective is to establish a new model of early diagnosis of metabolic diseases based on the respiratory and metabolic responses to transient 100% oxygen administration and ingestion of a standardised mixed meal. ANALYSIS: Raw data acquired with the CBmeter will be endorsed against gold standard techniques for heart rate, respiratory rate, oxygen saturation and interstitial glucose quantification and analysed a multivariate analysis software developed specifically for the CBmeter study (CBview). Data will be analysed using clustering analysis and artificial intelligence methods based on unsupervised learning algorithms, to establish the predictive value of diabetes diagnosis. ETHICS: The study was approved by the Ethics Committee of the Leiria Hospital Centre. Patients will be asked for written informed consent and data will be coded to ensure the anonymity of data. DISSEMINATION: Results will be disseminated through publication in peer-reviewed journals and relevant medical and health conferences.

Multicenter investigation on the influence of climate in penile prosthesis infection.

The purpose of this study is to investigate the relationship between inflatable penile prosthesis (IPP) infection, time of year, climate, temperature and humidity. This is a retrospective IRB-approved analysis of 211 patients at 25 institutions who underwent salvage procedure or device explant between 2001 and 2016. Patient data were compiled after an extensive review of all aspects of their electronic medical records. Climate data were compiled from monthly norms based on location, as well as specific data regarding temperature, dew point, and humidity from dates of surgery. Rigorous statistical analysis was performed. We found that penile prosthesis infections occurred more commonly in June (n = 24) and less frequently during the winter months (n = 39), with the lowest number occurring in March (n = 11). One-hundred thirty-nine infections occurred at average daily temperatures greater than 55 °F, compared to 72 infections at less than 55 °F. The incidence rate ratio for this trend was 1.93, with a p-value of <0.001. Humidity results were similar, and fungal infections correlate with daily humidity. Infected implants performed in the fall and summer were over 3 and 2.3 times, respectively, more likely to grow Gram-positive bacteria compared to implants performed in spring (p = 0.004; p = 0.039). This was consistent across geographic location, including in the Southern hemisphere. We found trends between climate factors and IPP infection like those seen and proven in other surgical literature. To our knowledge these data represent the first exploration of the relationship between temperature and infection in prosthetic urology.
