RESUMO

BACKGROUND: This study evaluated cardiovascular health, dietary habits, physical activity, depression, and sleep quality in young university adults. MATERIALS AND METHODS: A cross-sectional design was used to assess anthropometric, biochemical, and cardiovascular health behaviors. The study included 158 university students aged 18 to 30 years (65% women, 35% men, average age: 20.3 ± 2.4 years), selected through non-probabilistic sampling. Measurements included BMI, waist circumference, blood pressure, glucose, triglycerides, HDL and LDL cholesterol, and visceral fat using bioelectrical impedance. Health behaviors were evaluated via questionnaires on physical activity, fruit and vegetable consumption, smoking, ultra-processed food consumption, and sleep quality using the Pittsburgh Sleep Quality Index. The cardiovascular health index was assessed with the "Life's Essential 8" questionnaire and depression was assessed with Beck Depression Inventory. Statistical analyses included ANOVA, Fisher's F test, Student's t-test, and simple linear regression, conducted using SPSS Statistics version 25.0 (IBM Corp. Released 2017. IBM SPSS Statistics for Windows, Version 25.0. Armonk, NY: IBM Corp), with significance set at p<0.05. RESULTS: Women showed better adherence to healthy behaviors. Higher fruit and vegetable consumption and physical activity were associated with lower visceral fat. Higher visceral fat is correlated with increased blood pressure and decreased HDL cholesterol. Smoking and frequent ultra-processed food consumption were linked to higher depression scores, which were associated with poorer sleep quality. CONCLUSION: Healthy lifestyle habits are crucial for physical and mental health, providing a basis for public health interventions.

RESUMO

Introduction: Diabetes stands as one of the leading causes of death worldwide. Glucagon-like peptide-1 receptor agonists rank among the most effective medications for lowering blood glucose and body weight, as well as reducing cardiovascular risk in individuals with diabetes. Observational studies complement experimental evidence in new settings, different populations, and real-world healthcare practices. Methods: A multicentric observational study of adults with type 2 diabetes treated with once-weekly subcutaneous semaglutide in four health centers in Colombia was conducted. The protocol for the present study was not pre-registered. Results: Data from 186 patients were included. Most patients were women (57%) with a mean age of 62.8 ± 12.1 years. One year of once-weekly semaglutide usage was associated with a mean reduction in HbA1C of -1.47% (95% CI -1.76, -1.17), weight loss of -4.23 kg (95% CI -5.34, -3.12), and albumin/creatinine ratio of -18.6 mg/g (95% CI -60.2, -5.9). Approximately half the treated patients achieved a level of HbA1c ≤7% by the end of follow-up. Adverse events were rare and consistent with clinical trial safety profiles. Conclusion: In Colombia, administering semaglutide subcutaneously once a week over a 1-year period led to an average weight loss of 4.2 kg and a decrease of 1.4% in HbA1c.

RESUMO

Isolated optic nerve (ON) relapse is a rare occurrence in lymphoblastic leukemia (LBL). A 10-year-old boy with T-LBL presented 8 months after diagnosis with blurred vision and thickening of right ON on magnetic resonance imaging consistent with relapse. Cerebrospinal fluid and bone marrow were negative for leukemia. He received reinduction chemotherapy (including nelarabine and craniospinal radiation) followed by a myeloablative matched sibling donor bone marrow transplant. He remains in remission 2 years post-transplant with normal vision. We also review the literature for reports of isolated ON relapse in patients with LBL. Our patient's clinical course demonstrates that disease control can be achieved with early detection of ON relapse before disease progression.

RESUMO

Owing to their distinct physical and chemical properties, inorganic nanoparticles (NPs) have shown promising results in preclinical cancer therapy, but designing and engineering them for effective therapeutic purposes remains a challenge. Although a comprehensive database of inorganic NP research is not currently available, it is crucial for developing effective cancer therapies. In this context, machine learning (ML) has emerged as a transformative tool, but its adaptation to nanomedicine is hindered by inexistent or small datasets. Here we assembled a large database of inorganic NPs, comprising experimental datasets from 745 preclinical studies in cancer nanomedicine. Using descriptive statistics and explainable ML models we mined this database to gain knowledge of inorganic NP design patterns and inform future NP research for cancer treatment. Our analyses suggest that NP shape and therapy type are prominent features in determining in vivo efficacy, measured as a percentage of tumour reduction. Moreover, our database provides a large-scale open-access resource for discriminative ML that the broader nanotechnology community can utilize. Our work blueprints data mining for translational cancer research and offers evidence for standardizing NP reporting to accelerate and de-risk inorganic NP-based drug delivery, which may help to improve patient outcomes in clinical settings.

RESUMO

OBJECTIVE: To assess complications after ureteroscopy (URS) for upper tract urothelial carcinoma (UTUC) management and to assess its postoperative cumulative morbidity burden using the Comprehensive Complication Index (CCI). MATERIALS AND METHODS: Single center retrospective study including patients submitted to URS for UTUC suspicion. URSs were both diagnostic and operative. Postoperative complications were recorded according to the EAU Guidelines and graded according to Clavien-Dindo Classification (CDC). The cumulative postoperative morbidity burden developed by patients experiencing multiple events was assessed using the CCI. Multivariable logistic regression (MLR) analyses identified factors independently associated with the development of any grade and major postoperative complications. RESULTS: Overall, 360 patients with UTUC suspicion were included with a total of 575 URSs performed. The cumulative number of all postoperative complications recorded was 111. In 86 (15%) procedures, patients experienced at least one postoperative complication, while 25 (4.3%) experienced more than one complication. Of these, 16 (14%) were severe (CDC ≥ IIIa). The most frequent type of complications were urinary (34%), bleeding (30%) and infectious (30%). The higher the CDC grade, the higher the median CCI, with a statistically significant increase in median CCI from CDC II to major complications. Patients who experienced intraoperative complications were at higher risk of developing any grade and major postoperative complications at MLR. CONCLUSIONS: Complications after ureteroscopy for UTUC are relatively uncommon events. Patients who experience intraoperative complications are at higher risk of developing postoperative complications. The comprehensive complication index appeared more representative of the cumulative postoperative morbidity rather than the Clavien-Dindo classification.

RESUMO

PURPOSE: We aimed to accurately determine ureteral stricture (US) rates following urolithiasis treatments and their related risk factors. METHODS: We conducted a systematic review and meta-analysis following the PRISMA guidelines using databases from inception to November 2023. Studies were deemed eligible for analysis if they included ≥ 18 years old patients with urinary lithiasis (Patients) who were subjected to endoscopic treatment (Intervention) with ureteroscopy (URS), percutaneous nephrolithotomy (PCNL), or shock wave lithotripsy (SWL) (Comparator) to assess the incidence of US (Outcome) in prospective and retrospective studies (Study design). RESULTS: A total of 43 studies were included. The pooled US rate was 1.3% post-SWL and 2.1% post-PCNL. The pooled rate of US post-URS was 1.9% but raised to 2.7% considering the last five years' studies and 4.9% if the stone was impacted. Moreover, the pooled US rate differed if follow-ups were under or over six months. Patients with proximal ureteral stone, preoperative hydronephrosis, intraoperative ureteral perforation, and impacted stones showed higher US risk post-endoscopic intervention with odds ratio of 1.6 (P = 0.05), 2.6 (P = 0.009), 7.1 (P < 0.001), and 7.47 (P = 0.003), respectively. CONCLUSIONS: The overall US rate ranges from 0.3 to 4.9%, with an increasing trend in the last few years. It is influenced by type of treatment, stone location and impaction, preoperative hydronephrosis and intraoperative perforation. Future standardized reporting and prospective and more extended follow-up studies might contribute to a better understanding of US risks related to calculi treatment.

RESUMO

High incidences of congenital syphilis have been reported in areas along the Pacific coast of Colombia. In this retrospective study, conducted during 2018-2022 at a public hospital in Buenaventura, Colombia, we analyzed data from 3,378 pregnant women. The opportunity to prevent congenital syphilis was missed in 53.1% of mothers because of the lack of syphilis screening. Characteristics of higher maternal social vulnerability and late access to prenatal care decreased the probability of having >1 syphilis screening test, thereby increasing the probability of having newborns with congenital syphilis. In addition, the opportunity to prevent congenital syphilis was missed in 41.5% of patients with syphilis because of the lack of treatment, which also increased the probability of having newborns with congenital syphilis. We demonstrate the urgent need to improve screening and treatment capabilities for maternal syphilis, particularly among pregnant women who are more socially vulnerable.

RESUMO

BACKGROUND: Cervical cancer is a rare primary tumor resulting in metastases to the breast with few cases reported in literature. Breast metastases are associated with poor prognosis. The following case highlights the diagnostic challenges associated with metastatic cervical cancer to the breast along with individualized treatment. CASE SUMMARY: A 44-year-old G7P5025 with no significant past medical or surgical history presented with heavy vaginal to an outside emergency department where an exam and a pelvic magnetic resonance imaging showed a 4.5 cm heterogenous lobulated cervical mass involving upper two thirds of vagina, parametria and lymph node metastases. Cervical biopsies confirmed high grade adenocarcinoma with mucinous features. A positron emission tomography/computed tomography (PET/CT) did not show evidence of metastatic disease. She received concurrent cisplatin with external beam radiation therapy. Follow up PET/CT scan three months later showed no suspicious fluorodeoxyglucose uptake in the cervix and no evidence of metastatic disease. Patient was lost to follow up for six months. She was re-imaged on re-presentation and found to have widely metastatic disease including breast disease. Breast biopsy confirmed programmed death-ligand 1 positive metastatic cervical cancer. The patient received six cycles of carboplatin and paclitaxel with pembrolizumab. Restaging imaging demonstrated response. Patient continued on pembrolizumab with disease control. CONCLUSION: Metastatic cervical cancer to the breast is uncommon with nonspecific clinical findings that can make diagnosis challenging. Clinical history and immunohistochemical evaluation of breast lesion, and comparison to primary tumor can support diagnosis of metastatic cervical cancer to the breast. Overall, the prognosis is poor, but immunotherapy can be considered in select patients and may result in good disease response.

RESUMO

Photodynamic therapy (PDT), an emergent noninvasive cancer treatment, is largely dependent on the presence of efficient photosensitizers (PSs) and a sufficient oxygen supply. However, the therapeutic efficacy of PSs is greatly compromised by poor solubility, aggregation tendency, and oxygen depletion within solid tumors during PDT in hypoxic microenvironments. Despite the potential of PS-based metal-organic frameworks (MOFs), addressing hypoxia remains challenging. Boron dipyrromethene (BODIPY) chromophores, with excellent photostability, have exhibited great potential in PDT and bioimaging. However, their practical application suffers from limited chemical stability under harsh MOF synthesis conditions. Herein, we report the synthesis of the first example of a Zr-based MOF, namely, 69-L2, exclusively constructed from the BODIPY-derived ligands via a single-crystal to single-crystal post-synthetic exchange, where a direct solvothermal method is not applicable. To increase the PDT performance in hypoxia, we modify 69-L2 with fluorinated phosphate-functionalized methoxy poly(ethylene glycol). The resulting 69-L2@F is an oxygen carrier, enabling tumor oxygenation and simultaneously acting as a PS for reactive oxygen species (ROS) generation under LED irradiation. We demonstrate that 69-L2@F has an enhanced PDT effect in triple-negative breast cancer MDA-MB-231 cells under both normoxia and hypoxia. Following positive results, we evaluated the in vivo activity of 69-L2@F with a hydrogel, enabling local therapy in a triple-negative breast cancer mice model and achieving exceptional antitumor efficacy in only 2 days. We envision BODIPY-based Zr-MOFs to provide a solution for hypoxia relief and maximize efficacy during in vivo PDT, offering new insights into the design of promising MOF-based PSs for hypoxic tumors.

RESUMO

Therapy-related acute lymphoblastic leukemia (t-ALL) is a rare potential complication of chemotherapy. We describe the case of a 47-year-old male patient who was originally diagnosed with t(8;21) positive acute myeloid leukemia (AML) in 2019, received chemotherapy, achieved remission, and was disease-free for the next two years. During a routine follow-up in 2022, he was found to have developed subclinical pancytopenia, and further studies indicated a diagnosis of pH-negative, near-tetraploid B-cell acute lymphoblastic leukemia (B-ALL) that was positive for a Tier 1 TP53 mutation, consistent with t-ALL. The patient had a prolonged treatment course complicated by social factors, such as the impact of both disease and treatment on his ability to work enough to make a living and live life with the quality he desired. The patient elected to pause treatment and resume it at a later date, after which, unfortunately, significant disease progression occurred and the patient died from complicating neutropenic sepsis and variceal bleeding. This case illustrates the challenges of managing social circumstances and patient goals in the setting of medically necessary but potentially harsh treatment courses. Given the aggressive nature of t-ALL and its overall poor prognosis, goals of care must be re-evaluated and discussed often to ensure alignment of therapy with a patient's wishes.

RESUMO

AIM: The aim of this work is to evaluate the initial experience with water vapor thermal therapy (WVTT) for benign prostatic hyperplasia (BPH) in Spanish university hospitals, as well as to describe the differences in technique and follow-up between centers. MATERIALS AND METHODS: This retrospective observational multicenter study collected baseline characteristics, surgical, postoperative and follow-up data at 1, 3, 6, 12 and 24 months, including validated questionnaires, flowmetric variations, complications, and the need for pharmacological or surgical treatment following the procedure. Possible triggers for postoperative acute urinary retention (AUR) were also analyzed. RESULTS: A total of 105 patients were included. No differences were observed between the groups with and without AUR with respect to catheterization time (5 and 4.3 days respectively, P=.178), or prostate volume (47.9g and 41.4g respectively, P=.147). The mean improvement at 3, 6, 12 and 24 months in terms of peak flow was 5.3, 5.2, 4.2 and 3.8ml/s, respectively. As for ejaculation, an improvement was observed after 3 months of follow-up and was maintained over time. CONCLUSIONS: Minimally invasive treatment for BPH with WVTT shows good functional outcomes at 24 months follow-up, without significant impairment of sexual function and a low incidence of complications. There are minor inter-hospital variations, mainly in the immediate postoperative period.

RESUMO

BACKGROUND: Obesity is a known risk factor for developing endometrial cancer. However, the association of obesity with endometrial cancer (EC) outcomes has not been clearly established. This study examined how outcomes in women with early stage EC vary with body composition measured via computed tomography (CT). METHODS: In this retrospective study, patients diagnosed with EC international Federation of Gynecology and Obstetrics stages I-III and available CT scans were included. Automatica software was used to assess the areas of visceral adipose tissue, subcutaneous adipose tissue (SAT), and intermuscular adipose tissue (IMAT) and skeletal muscle area. RESULTS: Of 293 patient charts assessed, 199 met eligibility criteria. Median body mass index (BMI) was 32.8 kg/m2 (interquartile range [IQ] = 26.8-38.9); 61.8% had histologic subtype endometrioid carcinoma. Adjusted for age, international Federation of Gynecology and Obstetrics stage, and histologic subtype, a BMI of at least 30 vs less than 30 kg/m2 was associated with lower endometrial cancer-specific survival (ECSS) (hazard ratio [HR] = 2.32, 95% confidence interval [CI] = 1.27 to 4.25) and overall survival (OS) (HR = 2.7, 95% CI = 1.35 to 5.39). Higher IMAT 75th vs 25th percentile and SAT of at least 225.6 vs less than 225.6 cm2 were associated with lower ECSS (HR = 1.53, 95% CI = 1.1 to 2.13, and HR = 2.57, 95% CI = 1.13 to 5.88) and OS (HR = 1.50, 95% CI = 1.11 to 2.02, and HR = 2.46, 95% CI = 1.2 to 5.01), respectively. The association of visceral adipose tissue (75th vs 25th percentile) with ECSS and OS was not statistically significant (HR = 1.42, 95% CI = 0.91 to 2.22, and HR = 1.24, 95% CI = 0.81 to 1.89). CONCLUSION: Higher BMI, IMAT, and SAT were associated with higher mortality from EC and lower OS. A better understanding of the mechanisms underlying these relationships could inform strategies to improve patient outcomes.

RESUMO

INTRODUCTION: Kidney transplant (KT) recipients have a four-times higher risk of renal malignancies compared to general population. As these patients frequently harbor bilateral or multifocal tumors, the management of renal masses is still under debate. OBJECTIVE: To explore the current management of the native kidney masses in KT patients. ACQUISITION OF EVIDENCE: We performed a literature search on MEDLINE/PubMed database. A number of 34 studies were included in the present review. SYNTHESIS OF EVIDENCE: In frail patients with renal masses below 3 cm, active surveillance is a feasible alternative. Nephron-sparing surgery is not justified for masses in the native kidney. Radical nephrectomy is the standard treatment for post-transplant renal tumors of the native kidneys in KT recipients, with laparoscopic techniques leading to significantly less perioperative complication rates as compared to the open approach. Concurrent bilateral native nephrectomy at the time of transplantation can be considered in patients with renal mass and polycystic kidney disease, especially if no residual urinary output is present. Patients with localized disease and successful radical nephrectomy do not require immunosuppression adjustment. In metastatic cases, mTOR agents can ensure efficient antitumoral response, while maintaining proper immunosuppression in order to protect the graft. CONCLUSIONS: Post-transplant renal cancer of the native kidneys is a frequent occurrence. Radical nephrectomy is most frequently performed for localized renal masses. A standardized and widely-approved screening strategy for malignancies of native renal units is yet to be implemented.

RESUMO

Cancer remains one of the most challenging health problems worldwide, and localized therapeutic approaches based on micro/nanofibers have shown potential for its treatment. Micro/nanofibers offer several advantages as a drug delivery system, such as high surface area, tunable pore size, and sustained release properties, which can improve drug efficacy and reduce side effects. In addition, functionalization of these fibers with nanoparticles can enhance their targeting and therapeutic capabilities. Localized delivery of drugs and/or other therapeutic agents via micro/nanofibers can also help to overcome the limitations of systemic administration, such as poor bioavailability and off-target effects. Several studies have shown promising results in preclinical models of cancer, including inhibition of tumor growth and improved survival rates. However, more research is needed to overcome technical and regulatory challenges to bring these approaches to clinical use. Localized therapeutic approaches based on micro/nanofibers hold great promise for the future of cancer treatment, providing a targeted, effective, and minimally invasive alternative to traditional treatments. The main focus of this review is to explore the current treatments utilizing micro/nanofibers, as well as localized drug delivery systems that rely on fibrous structures to deliver and release drugs for the treatment of cancer in a specific area.

RESUMO

OBJECTIVE: To assess the oncologic outcomes and the safety profile of a reduced-dose versus full-dose BCG regimen in patients with non-muscle-invasive bladder cancer (NMIBC). MATERIAL AND METHODS: We performed a systematic review according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The PubMed, Embase, and Web of Science databases were searched in January 2022 for studies that analyzed oncological outcomes and compared between reduced- and full-dose BCG regimens. RESULTS: Seventeen studies including 3757 patients met our inclusion criteria. Patients who received reduced-dose BCG had significantly higher recurrence rates (OR 1.19; 95%CI, 1.03-1.36; p = 0.02). The risks of progression to muscle-invasive BC (OR 1.04; 95%CI, 0.83-1.32; p = 0.71), metastasis (OR 0.82; 95%CI, 0.55-1.22; p = 0.32), death from BC (OR 0.80; 95%CI, 0.57-1.14; p = 0.22), and all-cause death (OR 0.82; 95%CI, 0.53-1.27; p = 0.37) were not statistically different. When restricting the analyses to randomized controlled trials, we found similar results. In subgroup analysis, reduced dose was associated with a higher rate of BC recurrence in studies that used only an induction regimen (OR 1.70; 95%CI, 1.19-2.42; p = 0.004), but not when a maintenance regimen was used (OR 1.07; 95%CI, 0.96-1.29; p = 0.17). Regarding side effects, the reduced-dose BCG regimen was associated with fewer episodes of fever (p = 0.003), and therapy discontinuation (p = 0.03). CONCLUSION: This review found no association between BCG dose and BC progression, metastasis, and mortality. There was an association between reduced dose and BC recurrence, which was no longer significant when a maintenance regimen was used. In times of BCG shortage, reduced-dose regimens could be offered to BC patients.

RESUMO

BACKGROUND: Determining tumor necrosis factor-alpha inhibitors (anti-TNF-α) failure is still a challenge in the management of moderate-to-severe psoriasis. Thus, our comprehensive systematic literature review aimed to gather information on the criteria used to define anti-TNF-α failure. We also aimed to discover the main reasons for anti-TNF-α failure and define subsequently administered treatments. MATERIALS AND METHODS: We conducted a systematic review following review and reporting guidelines (Cochrane and PRISMA). International (Medline/PubMed and Cochrane Library) and Spanish databases (MEDES, IBECS), and gray literature were consulted to identify publications issued until April 2021 in English or Spanish. RESULTS: Our search yielded 58 publications. Of these, 37 (63.8%) described the criteria used to define anti-TNF-α primary or secondary failure. Criteria varied across studies, although around 60% considered Psoriasis Area and Severity Index (PASI)-50 criteria. Nineteen (32.8%) reported the reasons for treatment failure, including the lack or loss of efficacy and safety-related problems, mainly infections. Finally, 29 (50%) publications outlined the treatments administered after anti-TNF-α: 62.5% reported a switch to another anti-TNF-α and 37.5% to interleukin (IL)-inhibitors.Our findings suggest a need to standardize the management of anti-TNF-α failure and reflect the incorporation of new targets, such as IL-inhibitors, in the treatment sequence.KEY MESSAGESIn the treatment of psoriasis, the primary and secondary anti-TNF-α failure criteria differ widely in the scientific literature.The strictest efficacy criteria for defining anti-TNF-α failure, or those recommended by guidelines such as PASI75, were underused both in clinical trials and observational studies.Most studies failed to consider patient-reported outcomes in assessing psoriasis treatment efficacy, which contrasts with recent recommendations on the inclusion of patient-reported HRQoL as a supporting criterion when considering clinical outcomes.

RESUMO

Purpose: To describe our experience using virtual reality (VR) and three-dimensional (3D) printing as complements for the surgical planning process of slide tracheoplasty (ST) in patients with congenital tracheal stenosis (CTS). Description: VR and 3D printing are used for the surgical planning of ST as a therapeutic option in three female patients under five years of age with CTS. Evaluation: We assessed the planned surgical procedure, procedural time, postoperative complications, and outcomes, as well as the main surgeon's experience with the use of the applied technologies. Conclusions: The interaction within the VR environment allowed for collaboration of the surgical plan between surgical staff and enhancement of the radiologist-surgeon communication, while procedural simulation with 3D printing prototypes allowed for refining technical abilities for the surgical interventions. Based on our experience, the application of these technologies have added value to the surgical planning of ST and its outcomes in the treatment of CTS.

RESUMO

The systemic immune-inflammation index (SIII) is a marker studied in multiple types of urologic cancer. This systematic review evaluates the association between SIII values with overall survival (OS) and progression-free survival (PFS) in testicular cancer. We searched observational studies in five databases. The quantitative synthesis was performed using a random-effects model. The risk of bias was assessed using the Newcastle-Ottawa Scale (NOS). The only measure of the effect was the hazard ratio (HR). A sensitivity analysis was performed according to the risk of bias in the studies. There were 833 participants in a total of 6 cohorts. We found that high SIII values were associated with worse OS (HR = 3.28; 95% CI 1.3-8.9; p < 0.001; I2 = 78) and PFS (HR = 3.9; 95% CI 2.53-6.02; p < 0.001; I2 = 0). No indication of small study effects was found in the association between SIII values and OS (p = 0.5301). High SIII values were associated with worse OS and PFS. However, further primary studies are suggested to enhance the effect of this marker in different outcomes of testicular cancer patients.

RESUMO

Uveal melanomas are rare tumors arising from melanocytes that reside in the eye. Despite surgical or radiation treatment, approximately 50% of patients with uveal melanoma will progress to metastatic disease, most often to the liver. Cell-free DNA (cfDNA) sequencing is a promising technology due to the minimally invasive sample collection and ability to infer multiple aspects of tumor response. We analyzed 46 serial cfDNA samples from 11 patients with uveal melanoma over a 1-year period following enucleation or brachytherapy (n = ∼4/patient) using targeted panel, shallow whole genome, and cell-free methylated DNA immunoprecipitation sequencing. We found detection of relapse was highly variable using independent analyses (P = 0.06-0.46), whereas a logistic regression model integrating all cfDNA profiles significantly improved relapse detection (P = 0.02), with greatest power derived from fragmentomic profiles. This work provides support for the use of integrated analyses to improve the sensitivity of circulating tumor DNA detection using multi-modal cfDNA sequencing. Significance: Here, we demonstrate integrated, longitudinal cfDNA sequencing using multi-omic approaches is more effective than unimodal analysis. This approach supports the use of frequent blood testing using comprehensive genomic, fragmentomic, and epigenomic techniques.
