Visual Outcomes after Internal Limiting Membrane Peeling vs. Flap in the Closure of Full Thickness Macular Holes.

PURPOSE: To examine postoperative outcomes of internal limiting membrane peeling (ILMP) versus flap (ILMF) in the closure of full thickness macular holes (FTMH). METHODS: Retrospective chart review of patients who underwent pars plana vitrectomy and gas tamponade with ILMP or ILMF to close FTMH at the Atrium Health Wake Forest Baptist from January 2012 to October 2022 with at least 3 months follow up. Main outcome measures were type 1 primary FTMH closure and postoperative best corrected visual acuity (BCVA) in mean logMAR. RESULTS: 130 and 30 eyes underwent ILMP and ILMF respectively. There were no significant differences in baseline characteristics between the groups. 96% of ILMP eyes and 90% of ILMF eyes achieved primary hole closure (p=0.29). Among all eyes with primary hole closure, BCVA at 1 year was not different between the groups but when stratified by lens status, was superior in the ILMP versus ILMF group in pseudophakic eyes: the estimated least-squares mean BCVA (Snellen equivalent) [95% confidence interval] was 0.42 (20/50) [0.34, 0.49] in the ILMP group and 0.71 (20/100) [0.50, 0.92] in the ILMF group. CONCLUSIONS: ILMP and ILMF techniques yielded similarly high FTMH closure rates. In pseudophakic eyes with primary hole closure, ILMF eyes had worse BCVA at 1 year.

False-Positive Rate for Suspected Drug-Related Deaths Following Full Autopsy.

ABSTRACT: The sharp increase in drug-related deaths has tempted medical examiner/coroner offices to perform external examinations with comprehensive toxicology testing instead of performing a standard autopsy. Compounding the problem of an increasing workload has been the decrease in available forensic pathologists. Opting for external examinations on suspected drug-related fatalities, however, is antithetical to current best practices. The purpose of this study was to review case files, autopsy reports, and toxicologic results of all deaths that were autopsied at the authors' facility and decide whether significant disease processes or injuries that would supersede the results of toxicologic testing and external examination findings alone were being missed.

Comparison of Two Techniques for Proximal Margin Analysis of Toe Amputations: A Retrospective Review.

Toe amputations are a common podiatric procedure for treatment of osteomyelitis. Whether or not the surgeon obtains a surgical cure, thus resolving the infection, can be difficult to assess. Obtaining a proximal bone margin can assist the treatment team in deciding the duration of postoperative antibiotics, need for reoperation, and postoperative care. The two senior surgeons use different methods to analyze proximal bone margins. The first surgeon obtains a microbiologic culture from the remaining bone, either at the proximal phalanx or metatarsal head, following the removal of the toe to be reviewed for osteomyelitis. Per the second surgeon's technique, the pathologist only analyzes the proximal aspect of the amputated toe for presence of osteomyelitis. Our goal is to analyze the reoperation and reamputation rates between the techniques in which the proximal margin specimens are obtained. A retrospective chart review was performed on all isolated toe or partial toe amputations from March 2017 to September 2022. There were 115 patients who met inclusion criteria. Reoperation and reamputation rates were analyzed for positive and negative infection margins from intraoperative cultures. Our study found an overall 28% reoperation rate and 26% reamputation rate for the negative margins group. In the positive proximal margin group, there was an overall 48% reoperation rate and 44% reamputation rate. Our analysis did not find a statistically significant difference between the reamputation rate in the negative margins group and the reamputation rate in the positive margins group. In conclusion, our study found that a positive proximal margin for osteomyelitis exhibited a nearly double reoperation and reamputation rate compared to patients with a negative margin, and that one margin analysis technique was not inferior to the other in regards to the need for additional surgeries.

EUS-guided hepaticogastrostomy versus percutaneous transhepatic biliary drainage after failed ERCP: A propensity score-matched analysis.

Background and study aims Percutaneous transhepatic biliary drainage (PTBD) is the traditional second-line option after unsuccessful endoscopic retrograde cholangiopancreatography (ERCP). Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HG) is a viable alternative to PTBD. Our study aimed to compare outcomes of EUS-HG and PTBD for benign and malignant biliary diseases following failed ERCP. Patients and methods This single-center study retrospectively analyzed patients undergoing EUS-HG and PTBD for benign and malignant biliary disorders. A propensity score-matched analysis was performed using age, sex, and Charlson Comorbidity Index. The primary outcome was clinical success, which we defined as a decrease in total bilirubin by ≥ 50% at 2 weeks for malignant disease and resolution of the biliary disorder for benign disease. Results In total, 41 patients underwent EUS-HG and 138 patients underwent PTBD. After propensity score matching in a 1:2 ratio, 32 EUS-HG patients were matched with 64 PTBD. Technical success was achieved in 29 of 32 (91%) for EUS-HG and 63 of 64 (98%) for PTBD ( P =0.11). Clinical success was 100% for EUS-HG and 75% for PTBD ( P =0.0021). EUS-HG was associated with a lower adverse event rate (EUS-HG 13% vs. PTBD 58%, P <0.0001), shorter procedure duration (median 60 vs. 115 minutes, P <0.0001), shorter post-procedure length of stay (median 2 vs. 4 days, P <0.0001), and fewer reinterventions (median 1 vs. 3, P <0.0001). Conclusions Our results suggest that EUS-HG is superior to PTBD in the treatment of benign and malignant biliary disorders after failed ERCP.

Evaluating residual anti-Xa levels following discontinuation of treatment-dose enoxaparin in patients presenting for elective surgery: a prospective observational trial.

INTRODUCTION: Prior studies have demonstrated that patients presenting for elective surgery may have higher-than-expected residual anti-Xa level activity at or beyond 24 hours following their last treatment dose of enoxaparin. Given that 24 hours of abstinence is currently recommended by both European and American societies before the performance of neuraxial or deep anesthetic/analgesic procedures, determining the actual timeframe at which residual anti-Xa level activity reliably falls below 0.2 IU/mL, the lower limit of the target range for thromboprophylaxis, is critical. METHODS: This was a prospective observational trial. Consenting patients on treatment-dose enoxaparin were randomized to either a 24-hour group (last dose at 07:00 the day prior to surgery) or a 36-hour group (last dose at 19:00 2 days prior to surgery). On arrival for surgery, blood samples were obtained to assess residual anti-Xa level activity and renal function. The primary outcome was residual anti-Xa level activity following the last treatment dose of enoxaparin. Incorporating all patients, linear regression modeling was performed to predict the timepoint at which the level of anti-Xa activity reliably fell below 0.2 IU/mL. RESULTS: 103 patients were analyzed. Time from the last dose at which residual anti-Xa activity fell below 0.2 IU/mL, based on the upper bound of the 95% CI, was 31.5 hours. No correlation overall between age, renal function, or sex was found. CONCLUSION: Residual levels of anti-Xa activity do not reliably fall below 0.2 IU/mL 24 hours following discontinuation of treatment-dose enoxaparin. Therefore, current time-based guidelines are not conservative enough. Routine anti-Xa testing should be strongly considered, or current time-based guidelines should be reassessed. TRIAL REGISTRATION NUMBER: NCT03296033.

Analysis of adverse events with lumen apposing metal stents for drainage of pancreatic fluid collections.

Background and study aims Innovations in endoscopic management of pancreatic fluid collections (PFCs) using lumen apposing metal stents (LAMS) have rendered it a preferred approach for drainage of PFCs. These advances have not come without concern for adverse events (AEs). We present our experience with LAMS for drainage of PFCs and analyze factors that contribute to LAMS-related AEs. Patients and methods From November 2015 to October 2021, a retrospective analysis was performed of patients undergoing endoscopic management of PFCs using LAMS. All AEs were classified as either early (<48 hours) or late (>48 hours). Univariate and multivariate analysis were performed using logistic regression to assess the relationship between independent variables and AEs. Results A total of 119 patients with symptomatic PFCs underwent endoscopic drainage with LAMS. There were 16 AEs (12.4%). These included systemic inflammatory response syndrome (SIRS) (n=2), stent occlusion (n=5), bleeding (n=7), and stent migration (n=2). Univariate analysis of risk of AEs showed that no variables approached statistical significance. Of the seven patients who developed bleeding, five had pseudoaneurysms following LAMS placement and underwent angioembolization by an interventional radiologist. The average time to bleeding was 9.3 days (standard deviation 7.3) with all bleeding events occurring within 3 weeks. In a multivariate model, pseudocysts and presence of paracolic gutter extension were associated with an increased risk of bleeding. Conclusions Endoscopists should be aware of the risk factors for LAMS-related bleeding and tailor their drainage strategy, including utilization of plastic stents for drainage of pseudocysts and adherence to a strict imaging interval and follow-up protocol.

Fluid Intake Management in Maintenance Hemodialysis Using a Smartphone-Based Application: A Pilot Study.

Rationale & Objective: Increased interdialytic weight gain (IDWG) has been associated with increased morbidity and mortality. We evaluated the usefulness and safety of a mobile application (app) that allows patients receiving maintenance hemodialysis to self-monitor their daily fluid intake. Study Design: Within group comparison before or during intervention. Setting & Participants: Patients receiving maintenance hemodialysis with mean IDWG of <4%. Exposure: Participants were trained to use a smartphone-based app, FiApp that allowed them to record fluid intake and compare with individual targeted daily fluid intake determined by the nephrologist. Outcomes: The primary study outcome was the association between IDWG and fluid intake recorded in the FiApp. Secondary outcomes included FiApp safety and usage. Patient interviews were performed at weeks 1 and 4 to collect information regarding FiApp usability and recommendations for app improvements. Analytical Approach: Mean, median, and standard deviation. Results: Eighteen of 25 patients completed the full 4-week study, provided all app data, and completed 2 patient interviews. The mean 4-week IDWG during app use was similar to the baseline mean 4-week IDWG before app use; however, 61% of the participants had a decrease in IDWG when using the app compared with IDWG at baseline. Of the 18 participants who completed the study, only 1 had a mean 4-week IDWG that was 20% higher than that at baseline. The app was used on ≥80% of the days by 13 (72%) of 18 participants, and was used every day in 7 (39%) of 18 participants. The mean relationship between fluid reported in the app and fluid consumed was 40%. Limitations: This safety study recruited patients who had IDWG of <4%. Conclusions: A smartphone-based app can be safely used to help patients receiving maintenance hemodialysis track and control fluid intake. Motivated patients were able to decrease IDWG despite baseline IDWG being <4% of the body weight. Trial Registration: NCT03759847. Plain-Language Summary: Patients receiving maintenance hemodialysis struggle to limit fluid intake. Excess fluid intake can lead to adverse cardiovascular events. We developed a smartphone app to help patients receiving dialysis self-monitor their fluid intake. In this safety study in patients receiving dialysis with an interdialytic weight gain of <4% of the body weight, more than half of the patients were able to decrease their interdialytic fluid intake while using the app, and only 1 patient had an increase in interdialytic weight gain of >20% while using the app. Information gleaned from structured patient interviews will be used to refine this app.

Endoscopic Ultrasound-Guided Gallbladder Drainage: Beyond Cholecystitis.

Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) is an alternative to surgery for acute cholecystitis (AC) in poor operative candidates. However, the role of EUS-GBD in non-cholecystitis (NC) indications has not been well studied. We compared the clinical outcomes of EUS-GBD for AC and NC indications. Consecutive patients undergoing EUS-GBD for all indications at a single center were retrospectively analyzed. Fifty-one patients underwent EUS-GBD during the study period. Thirty-nine (76%) patients had AC while 12 (24%) had NC indications. NC indications included malignant biliary obstruction (n = 8), symptomatic cholelithiasis (n = 1), gallstone pancreatitis (n = 1), choledocholithiasis (n = 1), and Mirizzi's syndrome (n = 1). Technical success was noted in 92% (36/39) for AC and 92% (11/12) for NC (p > 0.99). The clinical success rate was 94% and 100%, respectively (p > 0.99). There were four adverse events in the AC group and 3 in the NC group (p = 0.33). Procedure duration (median 43 vs. 45 min, p = 0.37), post-procedure length of stay (median 3 vs. 3 days, p = 0.97), and total gallbladder-related procedures (median 2 vs. 2, p = 0.59) were similar. EUS-GBD for NC indications is similarly safe and effective as EUS-GBD in AC.

Adaptation of a Personalized Electronic Care Planning Tool for Cancer Follow-up Care: Formative Study.

BACKGROUND: Most patients diagnosed with colorectal cancer will survive for at least 5 years; thus, engaging patients to optimize their health will likely improve outcomes. Clinical guidelines recommend patients receive a comprehensive care plan (CP) when transitioning from active treatment to survivorship, which includes support for ongoing symptoms and recommended healthy behaviors. Yet, cancer care providers find this guideline difficult to implement. Future directions for survivorship care planning include enhancing information technology support for developing personalized CPs, using CPs to facilitate self-management, and assessing CPs in clinical settings. OBJECTIVE: We aimed to develop an electronic tool for colorectal cancer follow-up care (CFC) planning. METHODS: Incorporating inputs from health care professionals and patient stakeholders is fundamental to the successful integration of any tool into the clinical workflow. Thus, we followed the Integrate, Design, Assess, and Share (IDEAS) framework to adapt an existing application for stroke care planning (COMPASS-CP) to meet the needs of colorectal cancer survivors (COMPASS-CP CFC). Constructs from the Consolidated Framework for Implementation Research (CFIR) guided our approach. We completed this work in 3 phases: (1) gathering qualitative feedback from stakeholders about the follow-up CP generation design and workflow; (2) adapting algorithms and resource data sources needed to generate a follow-up CP; and (3) optimizing the usability of the adapted prototype of COMPASS-CP CFC. We also quantitatively measured usability (target average score ≥70; range 0-100), acceptability, appropriateness, and feasibility. RESULTS: In the first phase, health care professionals (n=7), and patients and caregivers (n=7) provided qualitative feedback on COMPASS-CP CFC that informed design elements such as selection, interpretation, and clinical usefulness of patient-reported measures. In phase 2, we built a minimal viable product of COMPASS-CP CFC. This tool generated CPs based on the needs identified by patient-completed measures (including validated patient-reported outcomes) and electronic health record data, which were then matched with resources by zip code and preference to support patients' self-management. Elements of the CFIR assessed revealed that most health care professionals believed the tool would serve patients' needs and had advantages. In phase 3, the average System Usability Scale score was above our target score for health care professionals (n=5; mean 71.0, SD 15.2) and patients (n=5; mean 95.5, SD 2.1). Participants also reported high levels of acceptability, appropriateness, and feasibility. Additional CFIR-informed feedback, such as desired format for training, will inform future studies. CONCLUSIONS: The data collected in this study support the initial usability of COMPASS-CP CFC and will inform the next steps for implementation in clinical care. COMPASS-CP CFC has the potential to streamline the implementation of personalized CFC planning to enable systematic access to resources that will support self-management. Future research is needed to test the impact of COMPASS-CP CFC on patient health outcomes.

Delayed endoscopic necrosectomy improves hospital length of stay and reduces endoscopic interventions in patients with symptomatic walled-off necrosis.

Objectives: Advancements in the endoscopic management of walled-off necrosis using lumen apposing metal stents have improved outcomes over its surgical and percutaneous alternatives. The ideal procedural technique and timing of direct endoscopic necrosectomy (DEN) have yet to be clarified. Methods: From November 2015 to June 2021, a retrospective comparative cohort analysis was performed comparing clinical outcomes for patients undergoing immediate DEN (iDEN) versus delayed DEN (dDEN). Subgroups were identified based on the quantification of necrosis. Wilcoxon two-sample tests were used to compare continuous variables and Fisher's exact test was used to compare categorical variables. Results: A total of 80 patients underwent DEN for management of walled-off necrosis (iDEN = 43, dDEN = 37). Technical success was achieved in all patients. Clinical success was seen in 39 (91%) patients in the iDEN group and 34 (92%) in the dDEN group. Amongst iDEN patients, the mean number of necrosectomies was 2.5 (standard deviation [SD] 1.4) in comparison to 1.5 (SD 1.0) for dDEN (p-value = 0.0011). The median index hospital length of stay was longer with iDEN than dDEN (7.5 days vs. 3.0 days respectively, p-value = 0.010). Subgroup analysis was performed based on the percentage of necrosis (<25% vs. >25% necrosis). iDEN was associated with more necrosectomies than dDEN regardless of the percentage of necrosis (p = 0.017 and 0.0067, respectively). Conclusion: Patients undergoing dDEN had a shorter index hospital stay and fewer necrosectomies than iDEN. The large diameter of lumen apposing metal stents permits adequate drainage allowing a less aggressive approach thereby improving clinical outcomes and avoiding unnecessary interventions.

Endoscopic management of hemorrhagic pancreatic fluid collections: A propensity-matched analysis.

Objectives: Hemorrhagic pancreatic fluid collections (hPFC) are a complication of pancreatitis with an unknown influence on prognosis. Advancements in endoscopic management of PFC have improved results over their surgical and percutaneous alternatives. We performed a propensity-matched analysis comparing clinical outcomes in hemorrhagic and non-hemorrhagic PFC (nhPFC). Methods: From November 2015 to November 2021, a retrospective comparative cohort analysis was performed comparing clinical outcomes for patients with hPFC and nhPFC managed with lumen-apposing metal stents. Propensity score matching was used to balance the two subgroups. Wilcoxon two-sample tests were used to compare continuous variables and Fisher's exact test was used to compare categorical variables. Kaplan-Meier method was used to estimate overall survival. Results: Fifteen patients with hPFC were matched with 30 nhPFC patients. Technical and clinical success was similar in both groups. The median length of hospitalization was 6 days in the hPFC group and 3 days in the nhPFC group (p = 0.23); however, more hPFC patients required intensive care unit admission post-procedure (33.3% vs. 16.7%, p = 0.26). Patients with hPFC were more likely to be readmitted to the hospital within 30 days (33.3% vs. 6.7%, p = 0.032). Mortality at 3 months (13% vs 3%, p = 0.25) and 6 months (27% vs. 7%, p = 0.09) was higher in the hPFC cohort. The 1-year survival estimate was 73.3% (standard error = 11.4) in the hPFC group and 88.9% (6.1) in the nhPFC group (p = 0.16). Conclusions: Patients with hPFC are more likely to be readmitted to the hospital within 30 days and have worse clinical outcomes.

Trends in the Diversity of Pediatric Faculty: 2000 to 2020.

OBJECTIVE: Academic medicine diversity is important for addressing health disparities and training the next generation. A recent study highlighted the lack of diversity among pediatric trainees over time. However, trends in US pediatric faculty diversity have not been clearly illuminated. The aim of this study is to evaluate pediatric faculty diversity trends and compare racial/ethnic representation between pediatric faculty and the US population. METHODS: Repeat cross-sectional study of the Association of American Medical Colleges Faculty Roster of pediatric faculty from 2000 to 2020. Trends in sex, race, ethnicity, and rank were compared with the Cochran-Armitage test. Data on faculty race/ethnicity were compared with the general and child population by using US Census Bureau data. RESULTS: Trends in underrepresented in medicine (URiM) faculty representation significantly increased at all ranks: professor (+3.5%, P < .0001), associate professor (+3.0%, P = .0001), and assistant professor (+2.5%, P = .0001). URiM male representation remained unchanged (P = .14), whereas significantly increased trends occurred in URiM female representation (+3.4%, P < .0001). African American/Black males significantly decreased representation at associate (-0.4%, P = .04) and assistant professor levels (-0.6%, P < .0001), and American Indian/Alaska Native males significantly decreased representation at the assistant professor rank (-0.1%, P < .0001). The percentage of URiM pediatric faculty representation was considerably lower compared with 2020 US overall and longitudinal child population representation. CONCLUSION: The stagnation of URiM male representation and lack of faculty diversity reflective of the US population may have a critical impact on the ability to recruit/retain a diverse pediatric workforce and promote equitable care.

Perioperative chemotherapy for resectable colorectal liver metastases: Analysis from the Colorectal Operative Liver Metastases International Collaborative (COLOMIC).

BACKGROUND: Chemotherapy has been increasingly combined with surgery as multimodality treatment for resectable colorectal-liver metastases (CLM). There is paucity of clinical data addressing optimal timing of chemotherapy relative to surgery. We examined outcomes of patients undergoing hepatectomy for resectable CLM. METHODS: Seven hundred and eighteen patients treated with hepatectomy for CLM were analyzed from five hepatobiliary institutions between 2000 and 2018. Overall survival (OS) was measured from time of hepatectomy for patients receiving: surgery alone, neoadjuvant, adjuvant, and neoadjuvant-plus-adjuvant (perioperative) chemotherapy. Kaplan-Meier analysis was performed to detect differences in OS between treatment groups. Single- and multi-variable analysis with Cox proportional hazards were run for OS between groups. RESULTS: One hundred and thirty-seven patients (19.08%) received surgery, 104 (14.48%) received neoadjuvant-only, 214 (29.81%) received adjuvant-only, and 263 (36.63%) received perioperative chemotherapy; with median OS of 48.20, 46.83, 56.27, and 49.93 months, respectively. No differences in median OS were seen between groups on Kaplan-Meier analysis. No significant difference in Charlson-Deyo comorbidity status was seen between groups (p = 0.853), while significant difference was seen in maximum tumor size (p = 0.0023). On multivariate analysis, adjuvant (p = 0.010) and perioperative (p = 0.020) chemotherapy were independently associated with OS compared to surgery alone. DISCUSSION: Despite group differences, chemotherapy after surgery was independently associated with improved OS in CLM.

Long-term transmural drainage of pancreatic fluid collections with double pigtail stents following lumen-apposing metal stent placement improves recurrence-free survival in disconnected pancreatic duct syndrome.

OBJECTIVES: Disconnected pancreatic duct syndrome (DPDS) is the most common cause of pancreatic fluid collection (PFC) recurrence. While long-term transmural drainage with plastic stents is the preferred endoscopic approach, there is a paucity of literature on patients undergoing initial drainage with lumen-apposing metal stents (LAMS). We describe our experience managing patients with DPDS. METHODS: A retrospective review of a prospectively maintained database (November 2015-September 2020) was performed looking at clinical outcomes and overall survival for patients undergoing endoscopic management of PFCs using LAMS. The primary outcome was to assess recurrence-free survival in PFC patients with DPDS managed with or without double pigtail stents (DPS) replacement after LAMS removal. RESULTS: Of 96 patients with PFCs, 48 with DPDS were included in the study. The median follow-up was 20.1 months. LAMS replacement with DPS was successful in 21/48 (43.8%) patients. Recurrence was seen in 1/21 (5%) patients with DPS replacement and 10/27 (37%) without DPS replacement. In multivariable models, a longer duration of LAMS placement was negatively associated with successful DPS replacement (odds ratio 1.33, 95% confidence interval [CI] 1.11, 1.59, P = 0.0019) and successful LAMS replacement with DPS in patients with DPDS improved recurrence-free survival (hazard ratio 0.09, 95% CI 0.01, 0.83, P = 0.033). CONCLUSION: In patients with PFCs and DPDS, early replacement of LAMS with DPS improves the likelihood of successful long-term transmural drainage and decreases recurrences.

New Razor Technology Improves Appearance and Quality of Life in Men With Pseudofolliculitis Barbae.

Pseudofolliculitis barbae (PFB) consists of ingrown hairs leading to papules, pustules, and discomfort. This prospective, 12-week clinical study aimed to assess the appearance of males with razor bumps and shaving irritation when using a new razor technology with 2 blades separated by a bridge feature (SkinGuard [Procter & Gamble]). The impact on participants' shave-related itching, burning, and stinging severity, as well as quality of life (QOL), also was assessed. In men with PFB, shaving with the test razor at least 5 times per week over a 12-week period improved the appearance and QOL of males with razor bumps and shaving irritation compared with baseline.

Diabetic Retinopathy Screening in Patients with Diabetes Using a Handheld Fundus Camera: The Experience from the South-Eastern Region in Hungary.

PURPOSE: Diabetic retinopathy (DR) is the leading cause of vision loss among active adults in industrialized countries. We aimed to investigate the prevalence of diabetes mellitus (DM), DR and its different grades, in patients with DM in the Csongrád County, South-Eastern region, Hungary. Furthermore, we aimed to detect the risk factors for developing DR and the diabetology/ophthalmology screening patterns and frequencies, as well as the effect of socioeconomic status- (SES-) related factors on the health and behavior of DM patients. METHODS: A cross-sectional study was conducted on adults (>18 years) involving handheld fundus camera screening (Smartscope Pro Optomed, Finland) and image assessment using the Spectra DR software (Health Intelligence, England). Self-completed questionnaires on self-perceived health status (SPHS) and health behavior, as well as visual acuity, HbA1c level, type of DM, and attendance at healthcare services were also recorded. RESULTS: 787 participants with fundus camera images and full self-administered questionnaires were included in the study; 46.2% of the images were unassessable. T1D and T2D were present in 13.5% and 86.5% of the participants, respectively. Among the T1D and T2D patients, 25.0% and 33.5% had DR, respectively. The SES showed significant proportion differences in the T1D group. Lower education was associated with a lower DR rate compared to non-DR (7.7% vs. 40.5%), while bad/very bad perceived financial status was associated with significantly higher DR proportion compared to non-DR (63.6% vs. 22.2%). Neither the SPHS nor the health behavior showed a significant relationship with the disease for both DM groups. Mild nonproliferative retinopathy without maculopathy (R1M0) was detected in 6% and 23% of the T1D and T2D patients having DR, respectively; R1 with maculopathy (R1M1) was present in 82% and 66% of the T1D and T2D groups, respectively. Both moderate nonproliferative retinopathy with maculopathy (R2M1) and active proliferative retinopathy with maculopathy (R3M1) were detected in 6% and 7% of the T1D and T2D patients having DR, respectively. The level of HbA1c affected the attendance at the diabetology screening (HbA1c > 7% associated with >50% of all quarter-yearly attendance in DM patients, and with 10% of the diabetology screening nonattendance). CONCLUSION: The prevalence of DM and DR in the studied population in Hungary followed the country trend, with a slightly higher sight-threatening DR than the previously reported national average. SES appears to affect the DR rate, in particular, for T1D. Although DR screening using handheld cameras seems to be simple and dynamic, much training and experience, as well as overcoming the issue of decreased optic clarity is needed to achieve a proper level of image assessability, and in particular, for use in future telemedicine or artificial intelligence screening programs.

Digital Image Analysis of the Angle and Optic Nerve: A Simple, Fast, and Low-Cost Method for Glaucoma Assessment.

PURPOSE: To devise a simple, fast, and low-cost method for glaucoma assessment using digital image analysis of the angle and optic nerve in human subjects. METHODS: Images from glaucoma and fundus assessment were used in this study, including color fundus photographs, standard optic nerve optical coherence tomography (OCT), and digital slit-lamp images of the angle/gonioscopy. Digital image conversion and analysis of the angle using ImageJ (NIH, USA) and adaptive histogram equalization contrast-limited AHE (CLAHE) to prevent noise amplification were implemented. Angle and optic nerve images were analyzed separately in the red, green, and blue (RGB) channels followed by 3D volumetric analysis of the degrees of angle depth and cup volume of the optic nerve. Horizontal tomogram reconstitution and nerve fiber detection methods were developed and compared to standard OCT images. RESULTS: Digital slit-lamp angle images showed similar accuracy as standard anterior OCT measurements. Comparative analysis of RGB channels produced volumetric cup and horizontal tomogram, which closely resembled the 3D OCT appearance and B-scan of the cup, respectively. RGB channel splitting and image subtraction produced a map closely resembling that of the retinal nerve fiber layer (RNFL) thickness map on OCT. CONCLUSIONS: While OCT imaging is rapidly progressing in the area of optic disc and chamber angle assessment, rising healthcare costs and lack of availability of the technology open a demand for alternative and cost-minimizing forms of image analysis in glaucoma. Volumetric, geometric, and segmentational data obtained through digital image analysis correspond well to those obtained by OCT imaging.

Ilioinguinal/Iliohypogastric versus quadratus lumborum nerve blockade for elective open inguinal herniorrhaphy: a prospective, randomized, double-blinded, equivalency trial.

BACKGROUND: Open inguinal herniorrhaphy (OIH) is a commonly performed surgical procedure with expected postoperative pain. Historically, an option for regional analgesia has been an ilioinguinal and iliohypogastric nerve block (IINB). More recently, the transmuscular quadratus lumborum block (QLB) has been used as an analgesic technique for a variety of abdominal and truncal surgical procedures. Given our own institutional experiences with the performance of QLB combined with the body of literature supporting the proximal blockade of the ilioinguinal and iliohypogastric nerves via this approach, we compared the analgesia provided by an IINB to a QLB. We hypothesized that the two blocks would provide equivalent analgesia, as defined by a difference of less than±2 points on the pain scale (0-10 numeric rating scale (NRS)), for patients undergoing OIH. METHODS: Sixty patients scheduled for elective outpatient OIH under general anesthesia were randomized to preoperatively receive either an IINB or a transmuscular QLB with 0.25% bupivacaine/epinephrine/clonidine for postoperative analgesia. The primary endpoint was movement NRS pain scores at 8 hours. Secondary outcomes included resting NRS pain scores at 8 and 24 hours, movement NRS pain scores at 24 hours, incidence of opioid related side effects (nausea, vomiting, pruritus), time-to-first oral opioid analgesic, and total opioid consumption at 24 hours. RESULTS: Fifty-nine patients were analyzed per an intention-to-treat approach (one patient was excluded because the surgical procedure was canceled). Movement pain scores at 8 hours were equivalent (IINB 5.10±3.02 vs QLB 5.03±3.01 (mean NRS±SD); two one-sided test mean difference (90% CI), 0.07 (-1.24 to 1.38), p ≤0.01). There were no differences between groups for any of the secondary endpoints. CONCLUSION: An IINB and a transmuscular QLB are equivalent with regards to their ability to provide postoperative analgesia after OIH.

Hepatic arterial infusion chemotherapy for colorectal liver metastases revisited.

BACKGROUND: Recent reports indicate improved survival in patients undergoing surgical treatment for colorectal liver metastases (CRLM) with hepatic arterial infusion (HAI) pump chemotherapy compared to surgery alone. METHODS: Patients who underwent resection and/or ablation of CRLM between 1996 and 2016 were included from a single-institution prospectively maintained database. Proportional hazards regression analysis was performed to determine predictors of overall survival (OS) and 3:1 propensity score analysis (PSA). RESULTS: Of 349 patients included, 36 had HAI pumps placed (HAI group) and 313 did not (no-HAI group). There was no difference in primary tumor grade (p = 0.24), ECOG status (p = 0.44), tumor number (p = 0.1), tumor size (p = 0.56), margin status (p = 0.76) between the two groups. Median overall survival was 44.7months vs 37.1months for the HAI versus no-HAI group (p = 0.01). Cox proportional hazards regression analysis demonstrated positive margin status (HR:2.47,p < 0.0001), HAI therapy (HR:0.56,p = 0.02), preoperative chemotherapy (HR:0.69,p = 0.02) and tumor diameter (HR:1.07,p = 0.005) as predictors of OS. In 3:1 PSA, 32 HAI subjects were matched with 87 non-HAI subjects balancing all covariates. Median OS was 42.4 months versus 35.6 months for the HAI versus no-HAI group (p = 0.03). CONCLUSION: Surgical treatment of CRLM combined with HAI chemotherapy is associated with improved OS compared to surgery alone. Further study of this treatment approach is indicated.
