Application of Natural Language Processing in Electronic Health Record Data Extraction for Navigating Prostate Cancer Care: A Narrative Review.

Introduction: Natural language processing (NLP)-based data extraction from electronic health records (EHRs) holds significant potential to simplify clinical management and aid research. This review aims to evaluate the current landscape of NLP-based data extraction in prostate cancer (PCa) management. Materials and Methods: We conducted a literature search of PubMed and Google Scholar databases using the keywords: "Natural Language Processing," "Prostate Cancer," "data extraction," and "EHR" with variations of each. No language or time limits were imposed. All results were collected in a standardized manner, including country of origin, sample size, algorithm, objective of outcome, and model performance. The precision, recall, and the F1 score of studies were collected as a metric of model performance. Results: Of the 14 studies included in the review, 2 articles focused on documenting digital rectal examinations, 1 on identifying and quantifying pain secondary to PCa, 8 on extracting staging/grading information from clinical reports, with an emphasis on TNM-classification, risk stratification, and identifying metastasis, 2 articles focused on patient-centered post-treatment outcomes such as incontinence, erectile, and bowel dysfunction, and 1 on loneliness/social isolation following PCa diagnosis. All models showed moderate to high data annotation/extraction accuracy compared with the gold standard method of manual data extraction by chart review. Despite their potential, NLPs face challenges in handling ambiguous, institution-specific language and context nuances, leading to occasional inaccuracies in clinical data interpretation. Conclusion: NLP-based data extraction has effectively extracted various outcomes from PCa patients' EHRs. It holds the potential for automating outcome monitoring and data collection, resulting in time and labor savings.

One-year outcomes after prostate artery embolization versus laser enucleation: A network meta-analysis.

Background: Although holmium laser enucleation (HoLEP) is considered a size-independent procedure for treatment of an enlarged prostate, prostate artery embolization (PAE) is emerging as an alternative modality to treat moderate and large benign prostatic hyperplasia. This study aims to compare the early post-operative and short-term efficacy of PAE and HoLEP. Methods: PubMed, Cochrane Library and EMBASE databases were searched. Network meta-analysis was performed following PRISMA-N-guidelines. Post-operative parameters analysed include international prostate symptom score (IPSS), quality of life (QOL), post-void residual urine (PVR), maximal uroflow rate (Qmax) and serious adverse events (SAE). Random effects model calculated weighted mean differences (WMD). If 95%CI crossed the line of no effect (WMD = 0), evidence indicated no statistically significant difference between treatments compared. Results: Qualitative and quantitative syntheses included 20 and 18 studies with 1991 and 1606 patients, respectively. At 3 months, there was no statistically significant difference between PAE and HoLEP in IPSS score improvement [WMD: -2.21: 95%CI: (-10.20, 5.78), favouring PAE], QoL score improvement [WMD: -0.22:95%CI: (-1.75, 1.32), favouring PAE] and PVR improvement [WMD: 26.97: 95%CI: (-59.53, 113.48), favouring HoLEP]. However, PAE was found inferior to HoLEP for Qmax improvement [WMD: 8.47, 95%CI: (2.89, 14.05), favouring HoLEP]. At 1-year follow-up, there was no statistically significant was found between PAE and HoLEP for IPSS score improvement [WMD:6.03, 95%CI: (-1.30, 13.35)], QoL score improvement [WMD: 0.03, 95%CI: (-1.19, 1.25)], PVR improvement [WMD:4.11, 95%CI: (-32.31, 40.53)] and Qmax improvement [WMD:2.60, 95%CI: (-2.20, 7.41)] with all differences favouring HoLEP. PAE was superior to HoLEP for SAE [PAE vs. HoLEP-OR: 0.68, 95%CI: (0.25, 1.37)]. Conclusion: HoLEP was superior to PAE at 3 months for Qmax improvement. There was no significant difference in IPSS, QoL, PVR and Qmax improvement at 1 year between PAE and HoLEP. PAE was also associated with lesser SAE compared to HoLEP. Studies on the long-term outcome of PAE are needed to establish the durability of early outcomes after PAE.

Minimally invasive techniques in quest of Holy Grail of surgical management of enlarged prostates: a narrative review.

PURPOSE: Past decade has seen a renewed interest in minimally invasive surgical techniques (MISTs) for management of enlarged prostate. This narrative review aims to explore newer MIST for benign prostatic hyperplasia (BPH) which are not yet integrated into established societal guidelines. METHODS: We conducted a literature search across PubMed, Google Scholar, and FDA ClinicalTrials.gov databases on June 1st, 2023, to identify studies published within the past decade exploring various MISTs for BPH. Additionally, we gathered insights from abstracts presented in meetings of professional associations and corporate websites. We broadly classified these procedures into three distinct categories: energy-based, balloon dilation, and implant/stent treatments. We collected detail information about the device, procedure details, its inclusion and exclusion criteria, and outcome. RESULTS: Our review reveals that newer energy-based MISTs include Transperineal Laser Ablation, Transurethral Ultrasound Ablation, and High-Intensity Focused Ultrasound. In the sphere of balloon dilation, Transurethral Columnar Balloon Dilation and the Optilume BPH Catheter System were gaining momentum. The noteworthy implants/stents that are on horizon include Butterfly Prostatic Retraction Device, Urocross Expander System, Zenflow Spring System, and ProVee Urethral Expander System. CONCLUSION: The exploration of various MISTs reflects ongoing efforts to enhance patient care and address limitations of existing treatments. This review provides a bird-eye view and valuable insights for urologists and researchers seeking to navigate the dynamic landscape of MISTs in the quest for effective and minimally invasive solutions for enlarged prostates.

Safety of Prostatic Artery Embolization via Transradial Access versus Transfemoral Access.

PURPOSE: To compare prostatic artery embolization (PAE) via transradial access (TRA-PAE) versus transfemoral access (TFA-PAE) to assist access selection. MATERIAL AND METHODS: Procedural outcomes and adverse events were evaluated in 998 patients who underwent PAE at a single center from April 2014 to August 2022; 821 (82%) underwent TRA-PAE (Group R) and 177 (18%) underwent TFA-PAE (Group F). Mean age and prostate size of Groups R and F were 69.2 years (SD ± 8.4) and 117.4 g (SD ± 63.1) and 75.2 years (SD ± 12.1) and 127.2 g (SD ± 83.6), respectively (P < .01 and P = .16; postpropensity matching: P = .38 and P = .35, respectively). Indications for PAE included lower urinary tract symptoms, acute or chronic urinary retention, and hematuria. Procedural and patient-specific metrics were reviewed. Technical success was defined as bilateral PAE. Adverse events were recorded according to the Society of Interventional Radiology (SIR) adverse events classification. Statistical significance was defined as P < .05. RESULTS: Technical success was achieved in 798 (97.2%) patients in Group R and 165 (93.2%) patients in Group F. Mean procedural time, single- and continuous-rotation fluoroscopy time, dose area product, and air kerma were significantly lower in Group R than in Group F (P < .001). Moreover, 6 (0.7%) patients in Group R and 9 (5.5%) patients in Group F had access site ecchymoses, whereas 5 (0.6%) patients in Group R and 6 (3.6%) in Group F had access site hematomas. Two patients experienced transient ischemic attacks (TIAs) after TRA-PAE and recovered without intervention. Two occult radial artery occlusions were noted, but no patient experienced hand ischemia. CONCLUSIONS: In a large single interventional radiologist cohort, TRA-PAE demonstrated similar technical success to that of TFA-PAE with lower access site hemorrhagic complications and radiation requirements; however, TIA and occult radial artery occlusions remain a concern.

Complications associated with minimally invasive surgical therapies (MIST) for surgical management of benign prostatic hyperplasia: a Manufacturer and User Facility Device Experience (MAUDE) database review.

PURPOSE: MAUDE database houses medical device reports of suspected device-related complications received by Food and Drug Administration. In the present study we aim to evaluate the MAUDE database for reported complications of MIST procedures. METHODS: The database was queried using keywords: rezum, urolift, prostate embolization (PAE), transurethral needle ablation (TUNA), transurethral microwave therapy (TUMT), prostate stent and Temporarily Implanted Nitinol Device (iTIND) on 10/1/22 to extract information regarding device problems and procedure-related complications. Gupta classification system was used to stratify complications. Statistical analysis was performed to compare frequency of complications among MIST procedures. RESULTS: We found a total of 692 reports (Rezum-358, urolift-226, PAE-53, TUNA-31, TUMT-19, prostatic stent-4, and iTIND-1). Most complications related to device or users were minor (level 1 and 2) and there was no significant difference among various MIST procedures. The screen/system error was responsible for 93% and 83% aborted cases in Rezum and TUNA, respectively, and PAE showed 40% of device component detachment/fracture. Overall Urolift and TUMT were associated with statistically significant higher incidence of major (level 3 and 4) complications (23% and 21%, respectively) as compared with Rezum (7%). Most major complications needing hospitalization after Urolift included hematoma and hematuria with clots and those after Rezum included urinary tract infection and sepsis. Thirteen deaths were reported, mostly due to cardiovascular events, which were classified as not associated with the proposed treatment. CONCLUSION: MIST for BPH can occasionally cause significant morbidity. Our data should assist urologists and patients in shared decision-making process.

The short-to-midterm outcomes of geniculate artery embolization for mild-to-moderate osteoarthritis of the knee: a systematic review.

Background: Geniculate Artery Embolization (GAE) is a novel, minimally-invasive treatment for mild to moderate Osteoarthritis (OA) associated with musculoskeletal pain. Purpose: To investigate the outcomes of GAE in patients with mild to moderate OA of the knee using a Quantitative-analysis of the available literature. Methods: The PubMed, EMBASE and Cochrane databases were searched for GAE-related studies. Qualitative and quantitative analyses were performed following PRISMA-guidelines. Quantitative-analysis was performed using windows based 'MedCalc-Statistical-Software version 19.6.1 (2020). Statistical analysis was performed in Stata-IC-13.1(Stata corp-USA). Quantitative-analysis was done using the random-effects model, and the Standardized-Mean-Differences (SMD) were calculated. Results: After a full-text review, 13 studies with 399 knees (345-patients) were included in the qualitative synthesis, 10 were included in the quantitative synthesis. The total WOMAC score improved by a [SMD (95% CI)] of 3.46 points (1.27, 5.65), 3.50 (1.28, 5.71), 3.77 (0.58, 6.96), 5.46 (1.59, 9.33), 2.96 (-0.93, 6.85) compared to baseline at 1, 3, 6, 12, 24 months respectively. The VAS score improved by 2.06 (1.35, 2.76), 2.13 (1.39, 2.87), 2.36 (1.85, 2.90), 2.09 (0.91, 3.28) compared to baseline at 1, 3, 6, 12 months respectively. The Pain WOMAC score improved by SMD 2.97 (0.51, 5.43), 3.77 (0.58, 6.96), 2.27 (0.31, 4.22), 2.27 (0.31, 4.22) compared to baseline at 1, 3, 12, 24 months, respectively. Conclusion: There was a statistically significant change from baseline in all outcome measures after GAE. GAE is a safe and effective method for pain control in mild to moderate OA-associated knee pain in the short and medium term.

Two-year outcomes comparing Embosphere® microspheres versus Imipenem Cilastatin for genicular artery embolization in patients with moderate to severe knee osteoarthritis.

BACKGROUND: Genicular artery embolization (GAE) is a novel technique and has the potential to provide midterm relief of pain for patients with mild-to-moderate knee osteoarthritis resistant to conservative management. This study compares the efficacy and safety of trisacryl gelatin microspheres to Imipenem/Cilastatin particles for GAE with 2 years of clinical follow-up. METHODS: In this retrospective study, eight patients with knee osteoarthritis (11 knees) who underwent GAE with 100-300 µm trisacryl gelatin microspheres particles were compared with six patients (nine knees) who underwent GAE with Imipenem/Cilastatin particles. Clinical outcomes were evaluated at 3-month and 24-month follow-ups and compared to baseline using the WOMAC questionnaire. RESULTS: The median follow-up was 796 days (range: 736-808). There were no significant differences in clinical outcome measures at the 3-month or 24-month follow-up. Both embolic materials resulted in a decrease in Pain WOMAC and Total WOMAC scores at 3 months (p < 0.05), and the effect of treatment on Pain WOMAC and Total WOMAC score reduction was sustained until the 24-month follow-up (p < 0.05). Minor events (Clavien-Dindo classification grade I) included transient cutaneous color change (n = 3) and transient leg numbness (n = 1) after embolization with trisacryl gelatin microspheres particles (p = 0.08). All minor adverse events resolved spontaneously. There were no major adverse events. CONCLUSION: One hundred to three hundred µm trisacryl gelatin microspheres particles can be considered for genicular artery embolization and is comparable to Imipenem/Cilastatin particles in pain reduction of moderate to severe knee osteoarthritis. A sustained effect is observed for up to 2 years of follow-up.

Long-Term Effects of Proximal Splenic Artery Embolization on Splenic Volume and Platelet Count.

BACKGROUND: The spleen is the most commonly injured visceral organ in blunt abdominal trauma. Post-splenectomy infection risk has led to the shift toward spleen preserving procedures and splenic artery embolization (SAE) is now the treatment of choice for hemodynamically stable patients with splenic injury. This study aims to assess the long-term effect of SAE on splenic volume and platelet count. MATERIALS AND METHODS: Using CPT codes, 66 patients who underwent SAE were identified, and 14 of those who had the necessary imaging and laboratory follow-up were included in the study. Indications for SAE were portal hypertension in 8 patients, bleeding in 4 patients, and thrombocytopenia in 1, and one patient had a separate indication. Splenic volume was calculated by automated volumetric software (Aquarius, TeraRecon, Inc.). Paired t-tests were performed to compare splenic volume and platelets before and after SAE. RESULTS: Fourteen patients (7 males, 7 females) with a mean age of 51 ± 11.95 years underwent SAE and were followed by a repeat computed tomography scan at an average of 733.57 days. Nine SAEs were performed using vascular plugs, 3 using micro coils, and 2 out of that were with Gelfoam slurry, and 2 using coils only. All embolizations were technically successful with complete cessation of flow. Mean splenic volumes pre- and post-SAE were 903.5 ± 523.73 cm3 and 746.5 ± 511.95 cm3, respectively, representing a mean decrease of 8.31% compared to baseline [P = 0.346]. Minimum platelet counts (x103) pre-SAE (within 3 months) and post-SAE (2 weeks to 3 months after the procedure) were 55.79 ± 57.11 and 116 ± 145.40, respectively. The minimum platelet count showed a statistically significant mean increase of 134.92% (P = 0.033). CONCLUSIONS: The splenic volume is not altered significantly by SAE in the long term. Similarly, the platelet count is also not significantly altered at 3 months follow-up. This study, although small, suggests that SAE is a safe intervention that can preserve splenic volume and function in the long term.

Prostatic Artery Embolization: Technical Pearls.

Benign prostatic hyperplasia (BPH) is a condition that primarily affects men between the fourth and seventh decades of life, occurring due to enlargement of the prostate which subsequently causes compression of the prostatic urethra causing chronic obstruction of the urinary outflow tract. BPH can cause significant quality-of-life issues such as urinary hesitancy, intermittency, decreased urinary stream, a sensation of incomplete emptying, dysuria, urinary retention, hematuria, and nocturia. Several medical and surgical treatment modalities are available for the treatment of lower urinary tract symptoms and other BPH-related sequela; however, increasingly prostate artery embolization is being utilized in this patient population. Technical demands for this procedure in this population can be significant. This article describes the optimal techniques, tricks, and advanced imaging techniques that can be used to achieve desired technical outcomes.

The untapped potential of Instagram to facilitate rheumatology academia.

Instagram allows for graphical and visual information exchange. This paper aims to explore the current landscape of rheumatology on Instagram and analyse the accounts available based on their objectives and level of engagement. The search term "#rheumatology" reveals 62 results, leaving 55 after careful exclusion. On grouping into "educational", "broadcasting", "support", and a combination of all three, an analysis is carried out using the total number of posts, follower counts, number of caption characters (last 10 posts), likes per post (last 10 posts), archived stories, reels, IgTV (Instagram Television) videos, hashtags, and links in bio. The analysis reveals that 29 accounts (52.7%) disseminate educational content, 36 (65.4%) are run by organisations, and 22 (40.0%) are of an institute or clinic. Character counts (rho 0.44, p = 0.0006) and videos (likes for ten posts 149 vs. 54, p = 0.006) positively correlate with the number of likes, while hashtag use and post count have no statistical significance with likes. Reels and IgTV videos are infrequently used (18.18%, 3.6%). The rheumatology social media landscape is in its nascency and currently split into educational and broadcasting accounts with a significant overlap between the two. The positive correlation of character counts and videos and the negative correlation of hashtag use and post count with likes lay the case for quality content to improve engagement. Social media editors may ensure quality content for rheumatology education using Instagram. Key Points • The current landscape of Instagram use in rheumatology is limited and largely orientated towards educative content. • Likes on Instagram are positively correlated with caption character counts and videos. • Using currently underutilised tools like videos, engaging captions, and infographics may enhance the utility of Instagram in rheumatology education.

Increased risk of mental health disorders in patients with RA during the COVID-19 pandemic: a possible surge and solutions.

Depression is a common co-morbidity among rheumatoid arthritis (RA) patients, which may translate into difficulty performing activities of daily living. COVID-19 is an unprecedented disaster that has disrupted lives worldwide and led to a rise in the incidence of mental health disorders. Given the widespread economic devastation due to COVID-19, many RA patients, already susceptible to mental illness, maybe at an increased risk of inaccessibility to medical care, accentuated stress, and consequent worsening of existent mental health disorders, or the onset of new mental health disorders such as anxiety, post-traumatic stress disorder, or depression. The objective of this review is to assess if there is an increased risk of mental health disorders in patients with RA during the COVID-19 pandemic. Telemedicine has bridged the transition to remote chronic care in the pandemic period, though certain accessibility and technological challenges are to be addressed. Decreased access to care amid lockdowns and a proposed triggering of disease activity in patients with autoimmune disorders may potentially herald a massive spike in incidence or flares of patients diagnosed with RA in the coming months. Such a deluge of cases may be potentially devastating to an overburdened healthcare system. Rheumatologists may need to prepare for this eventuality and explore techniques to provide adequate care during these challenging times. The authors found that there is a significant association between the adverse impact on the mental health of RA patients and the COVID-19 pandemic. However, more research is needed to highlight individual risk factors.
