Pathologic and Short-Term Oncologic Outcomes of Prostate Cancer Patients Following Transvesical Robot-Assisted Radical Prostatectomy.

PURPOSE: To study the pathologic and short-term oncological and survival outcomes following Transvesical Single-Port Robot-Assisted Radical Prostatectomy. MATERIALS AND METHODS: A retrospective review was performed on prospectively collected data on 169 patients with low and intermediate-risks prostate cancer, who either underwent Single-Port Transvesical or Multi-Port Transperitoneal Radical Prostatectomy by a single surgeon between 2015 and 2022. Preoperative clinicopathologic characteristics, as well as final histopathology outcomes, were compared. Univariate Cox proportional hazard analysis was used to evaluate the impact of the surgical approach on biochemical recurrence-free survival within 12 months. RESULTS: Single-Port Transvesical and Multi-Port Transperitoneal Robotic Radical Prostatectomy were completed in 85 and 84 patients, respectively. Preoperative clinicopathologic features were similar between the 2 groups. In terms of histopathology outcomes, the 2 groups had identical final Gleason Grades, T stage, as well as the rates of adverse pathological features and positive surgical margins (P = >0.05). Despite the lower median number of nodes in the single-port cohort of 2 (0-5) compared to 6 (4-9) in the multi-port cohort (P = <0.001), there remained no statistically significant difference in the rates of lymph node invasion (P = 0.08). At a median follow-up of 12 months, there were no differences in the biochemical recurrence-free survival rates among both groups (P = 0.38). Univariate Cox proportional hazard analysis did not consider surgical approach to be an independent predictor of biochemical recurrence (HR 0.53, 95%CI 0.13-2.23, P = 0.39). CONCLUSION: In well-selected patients, single-port transvesical robotic radical prostatectomy provided a similar short-term oncologic control as the multi-port approach with similar surgical margin status and 1-year biochemical recurrence rates.

Multidisciplinary hybrid approach to management of a thoracoabdominal aneurysm in a patient with both Loeys-Dietz and vascular Ehlers-Danlos syndrome.

Loeys-Dietz syndrome and vascular Ehlers-Danlos syndrome are genetic aortopathies that result from abnormal collagen matrix formation associated with vascular complications and early death. Identification of simultaneous COL3A1 and SMAD3 mutations as well as subsequent open and endovascular repair have not been reported. We present a case of a staged complete aortic replacement in a patient with a 7-cm aneurysm of his aortic arch and confirmed genetic mutations for Loeys-Dietz syndrome and vascular Ehlers-Danlos syndrome. This case highlights that, despite increased operative risk, successful staged repair of the entire aorta can be achieved in a patient with multiple severe genetic aortopathies.

Associations of PM2.5 exposure with emergency department visits and readmissions among preterm infants with bronchopulmonary dysplasia.

OBJECTIVES: To quantify the association of ambient air pollution (particulate matter, PM2.5) exposure with medically attended acute respiratory illness among infants with bronchopulmonary dysplasia (BPD). STUDY DESIGN: Single center, retrospective cohort study of preterm infants with BPD in Metropolitan Philadelphia. Multivariable logistic regression quantified associations of annual mean PM2.5 exposure (per µg/m3) at the census block group level with medically attended acute respiratory illness, defined as emergency department (ED) visits or hospital readmissions within a year after first hospital discharge adjusting for age at neonatal intensive care unit (NICU) discharge, year, sex, race, insurance, BPD severity, and census tract deprivation. As a secondary analysis, we examined whether BPD severity modified the associations. RESULTS: Of the 378 infants included in the analysis, 189 were non-Hispanic Black and 235 were publicly insured. Census block PM2.5 level was not significantly associated with medically attended acute respiratory illnesses, ED visits, or hospital readmissions in the full study cohort. We observed significant effect modification by BPD grade; each 1 µg/m3 higher annual PM2.5 exposure was medically attended acute respiratory illness (adjusted odds ratio [aOR] 1.65, 95% CI: 1.06-2.63) among infants with Grade 1 BPD but not among infants with grade 3 BPD (aOR 0.83, 95% CI: 0.47-1.48) (interaction p = .024). CONCLUSIONS: Cumulative PM2.5 exposure in the year after NICU discharge was not significantly associated with medically attended acute respiratory illness among infants with BPD. However, infants with Grade 1 BPD had significantly higher odds with higher exposures. If replicated, these findings could inform anticipatory guidance for families of these infants to avoid outdoor activities during high pollution days after NICU discharge.

The Tissue Systems Pathology Test Objectively Risk-Stratifies Patients With Barrett's Esophagus: Results From a Multicenter US Clinical Experience Study.

BACKGROUND: Barrett's esophagus (BE) is a diagnosis of esophageal intestinal metaplasia, which can progress to esophageal adenocarcinoma (EAC), and guidelines recommend endoscopic surveillance for early detection and treatment of EAC. However, current practices have limited effectiveness in risk-stratifying patients with BE. AIM: This study aimed to evaluate use of the TSP-9 test in risk-stratifying clinically relevant subsets of patients with BE in clinical practice. METHODS: TSP-9 results for tests ordered by 891 physicians for 8080 patients with BE with clinicopathologic data were evaluated. Orders were from nonacademic (94.3%) and academic (5.7%) settings for nondysplastic BE (NDBE; n=7586; 93.9%), indefinite for dysplasia (IND, n=312, 3.9%), and low-grade dysplasia (LGD, n=182, 2.3%). RESULTS: The TSP-9 test scored 83.2% of patients with low risk, 10.6% intermediate risk, and 6.2% high risk, respectively, for progression to HGD/EAC within 5 years. TSP-9 provided significant risk-stratification independently of clinicopathologic features, within NDBE, IND, and LGD subsets, male and female, and short- and long-segment subsets of patients. TSP-9 identified 15.3% of patients with NDBE as intermediate/high-risk for progression, which was 6.4 times more than patients with a pathology diagnosis of LGD. Patients with NDBE who scored intermediate or high risk had a predicted 5-year progression risk of 8.1% and 15.3%, respectively, which are similar to and higher than published progression rates in patients with BE with confirmed LGD. CONCLUSIONS: The TSP-9 test identified a high-risk subset of patients with NDBE who were predicted to progress at a higher rate than confirmed LGD, enabling early detection of patients requiring management escalation to reduce the incidence of EAC. TSP-9 scored the majority of patients with NDBE as low risk, providing support to adhere to 3- to 5-year surveillance per guidelines.

Combining genomic data and infection estimates to characterize the complex dynamics of SARS-CoV-2 Omicron variants in the US.

Omicron surged as a variant of concern in late 2021. Several distinct Omicron variants appeared and overtook each other. We combined variant frequencies and infection estimates from a nowcasting model for each US state to estimate variant-specific infections, attack rates, and effective reproduction numbers (Rt). BA.1 rapidly emerged, and we estimate that it infected 47.7% of the US population before it was replaced by BA.2. We estimate that BA.5 infected 35.7% of the US population, persisting in circulation for nearly 6 months. Other variants-BA.2, BA.4, and XBB-together infected 30.7% of the US population. We found a positive correlation between the state-level BA.1 attack rate and social vulnerability and a negative correlation between the BA.1 and BA.2 attack rates. Our findings illustrate the complex interplay between viral evolution, population susceptibility, and social factors during the Omicron emergence in the US.

Multidisciplinary Management of an Internal Carotid Artery Aneurysm Near the Skull Base.

Extracranial carotid artery aneurysms (ECAAs) are rare in comparison to the total number of peripheral artery aneurysms. Although there are multiple treatment modalities, no clear guidelines exist for the optimal management of ECAA. We describe a case of a 59-year-old female with an incidental finding of a 2.6 cm right internal carotid artery (ICA) aneurysm on computed tomography (CT) that was eventually excised via transcervical approach followed by end-to-end anastomosis with great saphenous vein (GSV) graft. To our knowledge, this case demonstrates a novel multidisciplinary approach to an ECAA near the skull base involving head and neck surgery (HNS), vascular surgery (VS), and neuro-interventional radiology (NIR).

Advanced repair of recurrent and low-large hysterotomy defects using a myometrial glide flap.

BACKGROUND: The resolution of factors linked to the recurrence of cesarean section defects can be accomplished through a comprehensive technique that effectively addresses the dehiscent area, eliminates associated intraluminal fibrosis, and establishes a vascularized anterior wall by creating a sliding myometrial flap. OBJECTIVE: Propose a comprehensive surgical repair for recurrent and large low hysterotomy defects in women seeking pregnancy or recurrent spotting. STUDY DESIGN: A retrospective cohort analysis included 54 patients aged 25-41 with recurrent large cesarean scar defects treated at Otamendi, CEMIC, and Valle de Lili hospitals. Comprehensive surgical repair was performed by suprapubic laparotomy, involving a wide opening of the vesicouterine space, removal of the dehiscent cesarean scar and all intrauterine abnormal fibrous tissues, using a glide myometrial flap, and intramyometrial injection of autologous platelet-rich plasma. Qualitative variables were determined, and descriptive statistics were employed to analyze the data in absolute frequencies or percentages. The data obtained were processed using the InfostatTM statistic program. RESULTS: Following the repair, all women experienced normal menstrual cycles and demonstrated an adequate lower uterine segment thickness, with no evidence of healing defects. All patients experienced early ambulation and were discharged within 24 h. Uterine hemostasis was achieved at specific points, minimizing the use of electrocautery. The standard duration of the procedure was 60 min (skin-to-skin), and the average bleeding was 80-100 ml. No perioperative complications were recorded. A control T2-weighted MRI was performed six months after surgery. All patients displayed a clean, unobstructed endometrial cavity with a thick anterior wall (Median: 14.98 mm, IQR 13-17). Twelve patients became pregnant again, all delivered by cesarean between 36.1 and 38.0 weeks, with a mean of 37.17 weeks. The thickness of the uterine segment before cesarean ranged between 3 and 7 mm, with a mean of 3.91 mm. No cases of placenta previa, dehiscence, placenta accreta spectrum (PAS), or postpartum hemorrhage were reported. CONCLUSIONS: The comprehensive repair of recurrent low-large defects offers a holistic solution for addressing recurrent hysterotomy defects. Innovative repair concepts effectively address the wound defect and associated fibrosis, ensuring an appropriate myometrial thickness through a gliding myometrial flap.

Bi-allelic variants in MYH3 cause recessively-inherited arthrogryposis.

Arthrogryposis is a clinical feature defined by congenital joint contractures in two or more different body areas which occurs in between 1/3000 and 1/5000 live births. Variants in multiple genes have been associated with distal arthrogryposis syndromes. Heterozygous variants in MYH3 have been identified to cause the dominantly-inherited distal arthrogryposis conditions, Freeman-Sheldon syndrome, Sheldon-Hall syndrome, and multiple pterygium syndrome. In contrast, MYH3 variants underlie both dominantly and recessively inherited Contractures, Pterygia, and Spondylocarpotarsal Fusion syndromes (CPSFS) which are characterized by extensive bony abnormalities in addition to congenital contractures. Here we report two affected sibs with distal arthrogryposis born to unaffected, distantly related parents. Sequencing revealed that both sibs were homozygous for two ultra-rare MYH3 variants, c.3445G>A (p.Glu1149Lys) and c.4760T>C (p.Leu1587Pro). Sequencing and deletion/duplication analysis of 169 other arthrogryposis genes yielded no other compelling candidate variants. This is the first report of biallelic variants in MYH3 being implicated in a distal arthrogryposis phenotype without the additional features of CPSFS. Thus, akin to CPSFS, both dominant and recessively inherited distal arthrogryposis can be caused by variants in MYH3.

Alternative proteoforms and proteoform-dependent assemblies in humans and plants.

The variability of proteins at the sequence level creates an enormous potential for proteome complexity. Exploring the depths and limits of this complexity is an ongoing goal in biology. Here, we systematically survey human and plant high-throughput bottom-up native proteomics data for protein truncation variants, where substantial regions of the full-length protein are missing from an observed protein product. In humans, Arabidopsis, and the green alga Chlamydomonas, approximately one percent of observed proteins show a short form, which we can assign by comparison to RNA isoforms as either likely deriving from transcript-directed processes or limited proteolysis. While some detected protein fragments align with known splice forms and protein cleavage events, multiple examples are previously undescribed, such as our observation of fibrocystin proteolysis and nuclear translocation in a green alga. We find that truncations occur almost entirely between structured protein domains, even when short forms are derived from transcript variants. Intriguingly, multiple endogenous protein truncations of phase-separating translational proteins resemble cleaved proteoforms produced by enteroviruses during infection. Some truncated proteins are also observed in both humans and plants, suggesting that they date to the last eukaryotic common ancestor. Finally, we describe novel proteoform-specific protein complexes, where the loss of a domain may accompany complex formation.

The Vertebrate Breed Ontology: Towards Effective Breed Data Standardization.

Background ­: Limited universally adopted data standards in veterinary science hinders data interoperability and therefore integration and comparison; this ultimately impedes application of existing information-based tools to support advancement in veterinary diagnostics, treatments, and precision medicine. Hypothesis/Objectives ­: Creation of a Vertebrate Breed Ontology (VBO) as a single, coherent logic-based standard for documenting breed names in animal health, production and research-related records will improve data use capabilities in veterinary and comparative medicine. Animals ­: No live animals were used in this study. Methods ­: A list of breed names and related information was compiled from relevant sources, organizations, communities, and experts using manual and computational approaches to create VBO. Each breed is represented by a VBO term that includes all provenance and the breed's related information as metadata. VBO terms are classified using description logic to allow computational applications and Artificial Intelligence-readiness. Results ­: VBO is an open, community-driven ontology representing over 19,000 livestock and companion animal breeds covering 41 species. Breeds are classified based on community and expert conventions (e.g., horse breed, cattle breed). This classification is supported by relations to the breeds' genus and species indicated by NCBI Taxonomy terms. Relationships between VBO terms, e.g. relating breeds to their foundation stock, provide additional context to support advanced data analytics. VBO term metadata includes common names and synonyms, breed identifiers/codes, and attributed cross-references to other databases. Conclusion and clinical importance ­: Veterinary data interoperability and computability can be enhanced by the adoption of VBO as a source of standard breed names in databases and veterinary electronic health records.

The dual prevalence of advanced degrees of obesity and heart failure: a study from the National Inpatient Sample database.

BACKGROUND: National prevalence rates for obesity and heart failure (HF) have been steadily increasing, which predisposes patients to higher morbidity and mortality rates. OBJECTIVES: The purpose of this study was to evaluate the prevalence of HF stages in hospitalized patients according to their body mass index (BMI). SETTING: Academic institution. METHODS: National Inpatient Sample data from 2016 to 2018 were examined to identify patients with obesity, HF (presence or absence of advanced HF [AHF]), and cardiogenic shock (CS). The proportion of hospital admissions was determined for each category on the basis of the presence of AHF with/without CS. A comparative analysis was performed between patients with and without AHF, and multivariate logistic regression analysis was performed for the event of AHF. The same analyses were performed for the event of CS. RESULTS: A total of 3,354,970 hospital admissions were identified. The prevalence of hospital admissions with a diagnosis of AHF and class III obesity and a diagnosis of CS and class III obesity was 21% and .5%, respectively. The prevalence of AHF and other classes of BMI and CS and other classes of BMI was 17% and .5%, respectively. The univariate analysis showed that there were significant variations in 10 factors between hospital admissions with/without the diagnosis of both AHF and CS. Statistical analyses indicated the following findings: Hospitalized patients in higher obesity groups are more likely to have AHF, and they are less likely to have CS compared with those with a BMI of ≤29.9. CONCLUSIONS: This study revealed that the prevalence of AHF was significantly higher in hospitalized patients with class III obesity. These findings have implications for clinical management, and it can be inferred that these patients are less likely to receive advanced cardiac replacement therapies and might benefit from innovative approaches to address severe dual morbidity.

Potential Risk Factors for Ocular Pain in Patients Undergoing Multiple Intravitreal Injections of Anti-Vascular Endothelial Growth Factor.

Purpose: To assess ocular pain in patients undergoing multiple intravitreal injections of anti-vascular endothelial growth factor (anti-VEGF) who have previous factors that may influence pain sensitivity. Methodology: This is a prospective, observational, case series study involving patients who underwent multiple (≥3) pro re nata intravitreal injections of ranibizumab or aflibercept to treat any cause of chorioretinal vascular disease. Ocular pain was assessed by the numerical analog scale during intravitreal injection. For this study, the main variable was ocular pain and the secondary variables included age, sex, previous history of glaucoma, primary retinal vascular disease, severe dry eye history, trigeminal pain, scleral buckle surgery, collagen diseases, fibromyalgia, severe migraine history, pars plana vitrectomy, scleral thickness measurements, and type of anti-VEGF. Results: In a total of 894 patients, 948 eyes (4822 intravitreal injections), 793 patients (88.6%) had ocular pain sensitivity between no pain to mild pain, 80 patients (8.9%) had moderate ocular pain, 15 patients (1.6%) had severe ocular pain, and 6 patients (0.7%) had extremely severe ocular pain. Patients with severe dry eye (p = 0.01) and previous history of scleral buckle surgery (p = 0.01) showed a significant correlation with ocular pain during intravitreal injection. Pars plana scleral thickness (>550 um) and diabetic neuropathy were associated with ocular pain but did not meet the criteria for statistical significance (p = 0.09 and p = 0.06, respectively). Conclusion: Dry eye and prior scleral buckle surgery may contribute to pain associated with intravitreal injection. These issues should be taken into consideration in patients undergoing multiple intravitreal injections.

Preoperative Prostate Magnetic Resonance Imaging-based Anatomical Predictors of Early Urinary Continence Following Single-port Transvesical Robot-assisted Radical Prostatectomy.

BACKGROUND AND OBJECTIVE: The introduction of the single-port (SP) robotic system has led to new approaches in robot-assisted radical prostatectomy (RARP), such as the transvesical (TV) approach, offering high rates of early urinary continence. While previous studies of SP TV RARP have identified perioperative factors influencing continence outcomes, the impact of anatomical factors remains unexplored. This study aims to assess magnetic resonance imaging (MRI)-based anatomical predictors of urinary continence after SP TV RARP. METHODS: A retrospective analysis of consecutive SP TV RARP cases (November 2020 to June 2023) with preoperative prostate MRI was performed. Two urogenital radiologists independently evaluated ten anatomical parameters to distinguish patients achieving urinary continence within 1 wk and 3 mo. Nonparametric methods estimated receiver operating characteristic curves (area under the curve [AUC]) and inter-reader agreement. KEY FINDINGS AND LIMITATIONS: In 120 cases, 40% achieved continence within 1 wk, rising to 71.7% by 3 mo. Membranous urethra length (MUL) alone was significantly associated with continence at 3 mo (AUC: 0.67, p = 0.003). At 1 wk, several parameters, including anteroposterior diameter of the prostate, coronal membranous urethra length, prostate volume, and transverse diameter of the prostate, showed promise in predicting continence. CONCLUSIONS AND CLINICAL IMPLICATIONS: A longer preoperative MUL was significantly associated with better odds of an early return to urinary continence after SP TV RARP. Each 1-mm increase in coronal MUL was associated with a 27% increase in the odds of continence at 3 mo. This information can aid in patient counseling and expectations preoperatively. PATIENT SUMMARY: Urinary incontinence is a common outcome after prostate cancer surgery, particularly in the early months. Recently, the single-port (SP) robotic system has emerged, localizing surgery to the diseased area. With the SP robot, accessing the prostate via the bladder leads to high rates of early continence. Our study reveals that the longer the urethral portion beneath the prostate, the higher the likelihood of regaining continence within 3 mo after surgery.

Supercritical Impregnation of PETG with Olea europaea Leaf Extract: Influence of Operational Parameters on Expansion Degree, Antioxidant and Mechanical Properties.

PETG (poly(ethylene glycol-co-cyclohexane-1,4-dimethanol terephthalate)) is an amorphous copolymer, biocompatible, recyclable, and versatile. Nowadays, it is being actively researched for biomedical applications. However, proposals of PETG as a platform for the loading of bioactive compounds from natural extract are scarce, as well as the effect of the supercritical impregnation on this polymer. In this work, the supercritical impregnation of PETG filaments with Olea europaea leaf extract was investigated, evaluating the effect of pressure (100-400 bar), temperature (35-55 °C), and depressurization rate (5-50 bar min-1) on the expansion degree, antioxidant activity, and mechanical properties of the resulting filaments. PETG expansion degree ranged from ~3 to 120%, with antioxidant loading ranging from 2.28 to 17.96 g per 100 g of polymer, corresponding to oxidation inhibition values of 7.65 and 66.55%, respectively. The temperature and the binary interaction between pressure and depressurization rate most affected these properties. The mechanical properties of PETG filaments depended greatly on process variables. Tensile strength values were similar or lower than the untreated filaments. Young's modulus and elongation at break values decreased below ~1000 MPa and ~10%, respectively, after the scCO2 treatment and impregnation. The extent of this decrease depended on the supercritical operational parameters. Therefore, filaments with higher antioxidant activity and different expansion degrees and mechanical properties were obtained by adjusting the supercritical processing conditions.

[HYPNOSTRESS study: Interest of medical hypnosis in the evaluation of perceived stress and the experience of hospitalization in an internal medicine department]. / Étude HYPNOSTRESS : intérêt de l'hypnose médicale dans l'évaluation du stress ressenti et le vécu d'une hospitalisation dans un service de médecine interne.

BACKGROUND: Patients with chronic illnesses, especially rare autoimmune and/or systemic diseases associated with significant diagnostic uncertainty, have a representation of their illness and a sometimes prolonged hospitalization experience that can be traumatic and anxiety-provoking. OBJECTIVE: The aim of this study was to evaluate the impact of a non-medicinal medical hypnosis intervention in reducing the stress state and improving the experience of patients hospitalized in an internal medicine department. METHODS: We conducted a prospective study of 24 patients hospitalized in the Internal Medicine Department of Lille University Hospital in 2023. Twelve patients received a non-drug medical hypnosis intervention known as the "place of safety" (case group) and were compared with 12 patients who did not (control group). Stress was assessed by the STAI questionnaire and hospitalization experience by a satisfaction questionnaire. RESULTS: The 24 patients, 13 of whom were women, had a mean age of 55±17 years at inclusion. On admission to hospital, the median STAI-ETAT between the two groups was 43.5 (38.0; 56.6) in the case group versus 42.0 (37.0; 48.5) in the control group (P=0.45). In the case group, the median STAI-ETAT questionnaire taken immediately after the hypnosis session was significantly lower than at the start of hospitalization (30.0 [25.5; 36.5] vs. 43.5 [38.0; 56.5] P=0.003), indicating a significant reduction in stress. At the end of hospitalization, there was also a significant persistence of the median significant reduction between cases and controls (29.5 [26.5; 35.0] for cases vs. 41.5 [33.5; 45.5] for controls P=0.002). Experience of hospitalization was better in the case group (median 5.0 [4.5; 5.0] vs. 4.0 [4.0; 4.5], P=0.016). CONCLUSION: This study suggests that medical hypnosis is a promising non-medicinal supportive intervention for reducing perceived stress and improving the experience of stress in patients hospitalized on an internal medicine ward.

An interdisciplinary approach helped to make a diagnosis, provide the necessary interventions, and start an adequate treatment.

A Cost Effectiveness Analysis of Avacincaptad Pegol for the Treatment of Geographic Atrophy with Comparison to Pegcetacoplan.

PURPOSE: The purpose of this study was to evaluate the cost effectiveness of the treatment of geographic atrophy (GA) with intravitreal avacincaptad pegol (ACP) and to compare it with pegcetacoplan (PEG). DESIGN: Cost analysis based on data from published studies. SUBJECTS: None; based on data from published sham control compared with 2 treatment groups in each of the index studies. METHODS: Costs were based on 2022 Medicare reimbursement data for both facility (hospital-based) and nonfacility settings in Miami. Specific usage and outcomes were derived from the GATHER2 study as well as DERBY and OAKS trials. For ACP, all patients were treated every month (EM) in year 1 then randomized to every other month (EOM) or EM in year 2. Two-year models were created for patients in the facility setting for extrafoveal (ACP and PEG) and all patients (PEG). MAIN OUTCOME MEASURES: Cost, cost utility, and cost per area of GA (in United States dollars). RESULTS: The cost to treat GA with ACP in EM and EOM treatment groups over the 2 years as reported was $67 400 and $40 600, respectively. With ACP treatment over 2 years, the daily cost of delaying GA 3.4 months (EM) and 4.5 months (EOM) was $649 (EM) and $356 (EOM). The (facility-based) costs per unit area of retinal pigment epithelium saved for patients with extrafoveal GA over the 2-year period were $119 000/mm2 (EM ACP) versus $54 000/mm2 (EM PEG) (P < 0.001), $57 100/mm2 (EOM ACP) versus $31 400/mm2 (EOM PEG) (P < 0.001), and $45 300/mm2 (hypothetical EOM from outset ACP). CONCLUSION: Treatment of GA with intravitreal ACP EOM was more cost effective than EM. When assessing extrafoveal lesions, ACP was less cost effective than PEG for both EM and EOM treatment.

Predictors of unsuccessful tuberculosis treatment outcomes in Brazil: an analysis of 259,484 patient records.

INTRODUCTION: Tuberculosis (TB) causes over 1 million deaths annually. Providing effective treatment is a key strategy for reducing TB deaths. In this study, we identified factors associated with unsuccessful treatment outcomes among individuals treated for TB in Brazil. METHODS: We obtained data on individuals treated for TB between 2015 and 2018 from Brazil's National Disease Notification System (SINAN). We excluded patients with a history of prior TB disease or with diagnosed TB drug resistance. We extracted information on patient-level factors potentially associated with unsuccessful treatment, including demographic and social factors, comorbid health conditions, health-related behaviors, health system level at which care was provided, use of directly observed therapy (DOT), and clinical examination results. We categorized treatment outcomes as successful (cure, completed) or unsuccessful (death, regimen failure, loss to follow-up). We fit multivariate logistic regression models to identify factors associated with unsuccessful treatment. RESULTS: Among 259,484 individuals treated for drug susceptible TB, 19.7% experienced an unsuccessful treatment outcome (death during treatment 7.8%, regimen failure 0.1%, loss to follow-up 11.9%). The odds of unsuccessful treatment were higher with older age (adjusted odds ratio (aOR) 2.90 [95% confidence interval: 2.62-3.21] for 85-100-year-olds vs. 25-34-year-olds), male sex (aOR 1.28 [1.25-1.32], vs. female sex), Black race (aOR 1.23 [1.19-1.28], vs. White race), no education (aOR 2.03 [1.91-2.17], vs. complete high school education), HIV infection (aOR 2.72 [2.63-2.81], vs. no HIV infection), illicit drug use (aOR 1.95 [1.88-2.01], vs. no illicit drug use), alcohol consumption (aOR 1.46 [1.41-1.50], vs. no alcohol consumption), smoking (aOR 1.20 [1.16-1.23], vs. non-smoking), homelessness (aOR 3.12 [2.95-3.31], vs. no homelessness), and immigrant status (aOR 1.27 [1.11-1.45], vs. non-immigrants). Treatment was more likely to be unsuccessful for individuals treated in tertiary care (aOR 2.20 [2.14-2.27], vs. primary care), and for patients not receiving DOT (aOR 2.35 [2.29-2.41], vs. receiving DOT). CONCLUSION: The risk of unsuccessful TB treatment varied systematically according to individual and service-related factors. Concentrating clinical attention on individuals with a high risk of poor treatment outcomes could improve the overall effectiveness of TB treatment in Brazil.
