RESUMO

Purpose: Facial feminization surgery (FFS) is associated with improved psychological outcomes in transgender patients. We aimed to evaluate the impact of FFS on patient satisfaction with facial appearance using validated, patient-reported outcome tools. Methods: Patients were recruited to complete a FACE-Q survey at least 6 months after their FFS. FACE-Q modules used included "Satisfaction with Facial Appearance Overall," "Facial Attributes" (forehead/eyebrows, nose, cheeks, cheekbone, chin, jawline, and neck), "Decision," "Outcomes," "Psychological Function," and "Social Function." "Satisfaction with Facial Appearance Overall" was compared to FACE-Q outcomes in transgender patients on hormone replacement therapy (HRT), alone. Results: Twenty-three patients completed the survey. Rhinoplasty was the most common procedure (82.6%). Insurance was rated as a major barrier in 50% of patients. "Satisfaction with Facial Appearance Overall" using the FACE-Q was 69.3, with "Psychological Function" rated at 73.7 and "Social Function" rated at 76.1. FFS was associated with a higher overall satisfaction in facial appearance compared to patients on HRT for 3 months (69.3 vs. 48.5, p<0.01) and 12 months, alone (69.3 vs. 54.4, p<0.001). Wait time for FFS of less than a year (ß=-20.4, p=0.04) and undergoing FFS at a younger age (ß=-1.4, p<0.001) were independently associated with higher satisfaction scores in overall facial appearance. Conclusions: FFS is associated with greater satisfaction with overall facial appearance, especially compared to transgender patients only on HRT. Insurance was the greatest barrier to receiving FFS. Improved access to surgery is needed to yield higher overall satisfaction with facial appearance.

RESUMO

Resource-poor areas with moisture deficit lands following aerobic and direct seeded rice (DSR) methods of cultivation face severe problems of iron deficiency. In this study, Bengal and Assam Aus rice panel was phenotyped at the seedling stage using an iron-deprived hydroponic medium for various shoot and root traits. A novel iron deficiency scoring scale was used to classify the tolerance reaction and could range anywhere between 0 and 9, indicating the most tolerant and susceptible, respectively. The GWAS results identified four putative candidate genes; OsFLA for number of leaves and shoot length, OsBIDK1 for root traits; average diameter, volume, biomass, projected area, and surface area, OsHPL3 for chlorophyll index of the third leaf and AKR2B (XBOS252) was for Fe score, (which was earlier reported in relation to Xa21). The nsSNP (nsSNPs) variations in these gene sequences were used to group the panel and identify superior haplotypes and donors. BR16 was identified as a superior donor, with higher chlorophyll index and shoot length than RA23, also higher values for root traits like root average diameter, root volume, root projected area and root surface area followed by Shete Bhado. The impact of identified nsSNPs on protein structure and stability was investigated. The conserved domains detected in the mutated proteins of the superior haplotypes are very informative, highlighting that natural selection favors abiotic stress tolerant variants in resource poor areas. Thus, justifying our choice of Aus landraces for association mapping of Fe deficiency tolerant genes in rice.

RESUMO

Acute gastric volvulus presents with the classic triad of severe epigastric pain, vomiting, and difficulty or inability to pass a nasogastric tube. It can be complicated by strangulation and perforation which are associated with high mortality rates. Quick diagnosis and attempt at decompression is paramount. Computer-aided tomography is an important diagnostic step, and findings such as gastric wall thickening, extraluminal gas, and mediastinal fluid should prompt urgent surgical intervention. Approaches can include minimally invasive or open operations and in general should include reduction of the hernia, resection of devitalized tissue, and in some cases esophageal exclusion with delayed reconstruction.

RESUMO

Comprehensive biomarker testing for patients with non-small cell lung cancer is critical for selecting appropriate targeted therapy or immunotherapy. Ensuring timely ordering, processing, and reporting is key to optimizing patient outcomes. However, various factors can prevent or delay patients from being offered the option of treatment selection based on comprehensive biomarker testing. These factors include problems with access to testing, tissue adequacy, turnaround time, and health insurance coverage and billing practices. Turnaround time depends on several logistical and tissue handling factors, which involve institutional policies, processes, resources, testing methodology, and testing algorithms that vary across different practices. In this article, the authors identify key factors that prolong biomarker testing turnaround time, propose strategies to reduce it, and present a process map to aid physicians and key organizational stakeholders in improving testing efficiency.

RESUMO

Comprehensive biomarker testing is a crucial requirement for the optimal treatment of advanced-stage non-small cell lung cancer (NSCLC), with emerging relevance in the adjuvant treatment setting. To advance its goal of ensuring optimal therapy for persons diagnosed with lung cancer, the American Cancer Society National Lung Cancer Roundtable (ACS NLCRT) held The Summit on Optimizing Lung Cancer Biomarkers in Practice in September 2020 to align its partners toward the goal of ensuring comprehensive biomarker testing for all eligible patients with NSCLC. The ACS NLCRT's Strategic Plan for Advancing Comprehensive Biomarker Testing in NSCLC, a product of the summit, comprises actions to promote comprehensive biomarker testing for all eligible patients. The approach is multifaceted, including policy-level advocacy and the development and dissemination of targeted educational materials, clinical decision tools, and guides to patients, physicians, and payers aimed at ameliorating barriers to testing experienced by each of these groups. PLAIN LANGUAGE SUMMARY: The ACS NLCRT works to improve care for patients with lung cancer. The ACS NLCRT supports comprehensive biomarker testing as essential to determine treatment options for all eligible patients with non-small cell lung cancer. Many factors lead to some patients not receiving optimal biomarker testing. The ACS NLCRT held a collaborative summit and developed a strategic plan to achieve and promote comprehensive biomarker testing for all patients. These plans include developing educational materials and physician tools and advocating for national policies in support of biomarker testing.

RESUMO

BACKGROUND: The risk of herpes zoster in patients treated with temozolomide is poorly defined in the literature. We aimed to evaluate the incidence of and risk factors for herpes zoster in individuals receiving temozolomide for glioma. METHODS: A retrospective observational study was conducted on a series of patients treated with temozolomide for glioma at a single centre between 1 October 2018 and 30 September 2023. RESULTS: 131 patients were treated with temozolomide for glioma with a median age of 55 years. 4 out of 131 patients (3.1 %) developed herpes zoster during temozolomide treatment. All cases of herpes zoster occurred in patients who had lymphocyte nadirs of less than 0.7 x 109/L and were receiving corticosteroids concomitantly. The estimated herpes zoster incidence rates were 45.44 per 1000 person-years (95 % confidence interval (CI) 12.38-116.34 per 1000 person-years) in the overall study population and 224.97 per 1000 person-years (95 % CI 61.30-576.02 per 1000 person-years) in subjects who were treated with corticosteroids and had a lymphocyte nadir of less than 1.0 x 109/L. CONCLUSION: Use of temozolomide, particularly in conjunction with lymphopaenia or corticosteroid use, poses a risk of herpes zoster. Further research into the benefits of prophylactic antiviral measures in this population is recommended.

RESUMO

Fluorescent proteins (FPs) are essential tools in biology. The utility of FPs depends on their brightness, photostability, efficient folding, monomeric state, and compatibility with different cellular environments. Despite the proliferation of available FPs, derivatives of the originally identified Aequorea victoria green fluorescent protein often show superior behavior as fusion tags. We recently generated msGFP2, an optimized monomeric superfolder variant of A. victoria GFP. Here, we describe two derivatives of msGFP2. The monomeric variant msYFP2 is a yellow superfolder FP with high photostability. The monomeric variant moxGFP2 lacks cysteines but retains significant folding stability, so it works well in the lumen of the secretory pathway. These new FPs are useful for common imaging applications.

RESUMO

The initial management of patients with lung cancer is growing more complex in the context of an expanding number of precision medicine treatments. These challenges are accompanied by opportunities to deliver more efficacious and less toxic treatments to patients. Indications for these treatments are also expanding, and patients with lung cancer across multiple stages now require biomarker testing. Given their role in the initial management of patients being diagnosed with lung cancer, pulmonologists must have fundamental knowledge regarding the importance, indications, and implications of biomarker testing across the spectrum of histology and stage. The purpose of this review is to provide fundamental knowledge regarding biomarker testing, its incorporation into the initial diagnostic and staging evaluation, and guidance for working within a multidisciplinary team to achieve timely and comprehensive biomarker testing to direct the use of precision medicine treatments.

RESUMO

Subcutaneous granuloma annulare (SGA) is a rare clinicopathologic subtype of granuloma annulare characterized by the presence of subcutaneous nodules. There are no present reviews synthesizing the clinical features and treatment modalities in SGA. We conducted a systematic review following PRISMA guidelines [CRD42022344672] on all peer-reviewed English-language studies that reported one or more cases of SGA. A total of 97 studies, comprising 26 case series and 71 case reports with 324 patients, were included for analysis. Most cases were predominantly pediatric, with 78.9% of the cases identified being age 16 or lower and a median age of diagnosis of 6. There was no overall gender predisposition. Although over two-thirds of patients did not have any comorbidities, diabetes mellitus was the most common comorbidity present in 4% of cases. The most common feature of SGA was nodules, which were present in 99.6% of patients. Pain or tenderness was reported in 15.4%, and erythema of overlying skin in 11.0% of cases. Surgical excision was performed in 96/141 (68.1%) patients. Among the 27/141 (18.0%) patients who were conservatively managed, 87.0% spontaneously improved, including 60.0% who completely self-resolved. Topical and intralesional steroids were used in 3.40% and 1.85% of patients, respectively, resulting in complete or partial resolution in 54.6% and 100%. Among patients who were followed up, 83/324 (25.6%) patients experienced recurrence after a median duration of 26 weeks. SGA is predominantly a pediatric disease that frequently occurs on the limbs and the head. Juxta-articular lesions are more commonly observed in adults than in children. Surgical excision is common and effective in most patients. Spontaneous improvement occurs in most untreated cases, and intralesional steroids but not topical steroids may be beneficial for non-resolving cases and to reduce time to resolution.

RESUMO

OBJECTIVE: To compare the efficacy and clinical outcomes of computed tomography (CT)-based virtual surgical planning (VSP) and a three-dimensional (3D)-printed, patient-specific reduction system to conventional indirect reduction techniques for diaphyseal tibial fractures stabilized using minimally invasive plate osteosynthesis (MIPO) in dogs. STUDY DESIGN: A prospective clinical study with a historic control cohort. SAMPLE POPULATION: Dogs undergoing MIPO stabilization of diaphyseal tibial fractures using a custom 3D-printed reduction system (3D-MIPO; n = 15) or conventional indirect reduction techniques (c-MIPO; n = 14). METHODS: Dogs were prospectively enrolled to the 3D-MIPO group and CT scans were used to design and fabricate a custom 3D-printed reduction system to facilitate MIPO. Medical records were searched to identify dogs for the c-MIPO group. Pre-, intra- and postoperative parameters were compared between groups. RESULTS: The duration from presentation until surgery was 23 h longer in the 3D-MIPO group (p = .002). Fewer intraoperative fluoroscopic images were acquired (p < .001) and mean surgical duration was 34 min shorter in the 3D-MIPO group (p = .014). Median postoperative tibial length, frontal alignment, and sagittal alignment were within 4 mm, 3° and 3°, respectively, of the contralateral tibia in both groups and did not differ between reduction groups (p > .1). Postoperative complications occurred in 27% and 14% of fractures in the 3D-MIPO and c-MIPO groups, respectively. CONCLUSION: Both reduction methods yielded comparable results. Although the preoperative planning and guide preparation was time consuming, surgery times were shorter and fluoroscopy use was less in the 3D-MIPO group. CLINICAL SIGNIFICANCE: VSP and the custom 3D-printed reduction system facilitated efficient MIPO.

RESUMO

Guideline recommended standard of care screening is available for four cancer types; most cancer-related deaths are caused by cancers without standard of care screening. DETECT-A is the first prospective interventional trial evaluating a multi-cancer early detection (MCED) blood test (CancerSEEK) in women without a history of cancer, providing the first opportunity to assess the long-term outcomes of individuals with false-positive (FP) MCED results. This prospective analysis of DETECT-A participants with FP results evaluates the performance of an imaging-based diagnostic workflow and examines cancer risk following a FP result. This analysis included all DETECT-A participants with a positive CancerSEEK test and subsequent flourine-18 fluorodeoxyglucose positron emission tomography-IV contrast-enhanced computed tomography (18-F-FDG PET-CT) imaging and clinical workup indicating no evidence of cancer within 1 year of enrollment (n = 98). Medical records, study interactions, and study surveys were used to assess cancer incidence, treatments, and clinical outcomes through August 2023. Ninety-five of 98 participants with a FP result remained cancer-free with a median follow-up of 3.6 years (IQR: 2.5-4.1) from determination of FP status. Three incident cancers were observed over the follow-up period. One bilateral stage IIIC ovarian cancer was diagnosed 1.9 years after determination of FP status; two stage I breast cancers were diagnosed 0.1 and 1.6 years from determination of FP status. The annual incidence rate of cancer during follow-up from FP determination was 1.0% (95% confidence interval, 0.2%-2.8%). Participants with a positive CancerSEEK test who underwent 18-F-FDG PET-CT and clinical workup without cancer findings had low risk for cancer over the following several years. Prevention Relevance: This study provides multiyear clinical outcomes data following a false-positive multi-cancer early detection test for individuals participating in a prospective interventional trial. It provides a preliminary performance assessment of an imaging-based diagnostic workflow following a false-positive multi-cancer early detection test.

RESUMO

The phenomenon of mixed/heterogenous treatment responses to cancer therapies within an individual patient presents a challenging clinical scenario. Furthermore, the molecular basis of mixed intra-patient tumor responses remains unclear. Here, we show that patients with metastatic lung adenocarcinoma harbouring co-mutations of EGFR and TP53, are more likely to have mixed intra-patient tumor responses to EGFR tyrosine kinase inhibition (TKI), compared to those with an EGFR mutation alone. The combined presence of whole genome doubling (WGD) and TP53 co-mutations leads to increased genome instability and genomic copy number aberrations in genes implicated in EGFR TKI resistance. Using mouse models and an in vitro isogenic p53-mutant model system, we provide evidence that WGD provides diverse routes to drug resistance by increasing the probability of acquiring copy-number gains or losses relative to non-WGD cells. These data provide a molecular basis for mixed tumor responses to targeted therapy, within an individual patient, with implications for therapeutic strategies.

RESUMO

BACKGROUND: Despite advances in precision medicine for non-small cell lung cancer (NSCLC), biomarker testing for these therapies remain frequently underused, delayed, and inequitable. Pulmonologists often play a critical role in the initial diagnostic steps for patients with lung cancer, and previous data show variability in their knowledge and practices regarding biomarker testing. The purpose of this study is to better understand how pulmonologists view their role in lung cancer care. RESEARCH QUESTION: With the increasing importance of biomarker testing and precision medicine, how do pulmonologists view their role in lung cancer care? STUDY DESIGN: An electronic survey consisting of 31 items focused on attitudes and practices regarding diagnostic steps for NSCLC was randomly distributed to a sample of practicing pulmonologists in the American College of Chest Physicians (CHEST) analytics database. Inferential statistics were performed using χ2 tests and multivariable logistic regression models. RESULTS: A total of 401 pulmonologists responded to the survey. Most (92%) were general pulmonologists, and more than half (62%) indicate they order biomarker testing. Longer practice tenure, higher case volumes, and participation in a multidisciplinary tumor board were associated with ordering biomarkers (P < .05). Pulmonology was identified to have the leading responsibility for the initial diagnostic biopsy by most respondents (83%) and less often for staging (45%), leading discussions about biomarker testing with patients (28%), and for ordering biomarkers (22%). The most common reasons for not ordering biomarkers included the following: oncology was responsible (84%), it was not within their scope of practice (46%), or lack of the necessary knowledge (51%). INTERPRETATION: Pulmonologists vary in their practices for ordering biomarkers, and many defer this responsibility to oncology. Despite the role of bronchoscopy and pulmonology societal guidelines for staging, many defer leadership of this process. Many pulmonologists lack the necessary resources and multidisciplinary infrastructure likely required to efficiently accomplish biomarker testing.

RESUMO

OBJECTIVE: To evaluate the efficacy of a three-dimensional (3D)-printed, patient-specific reduction system for aligning diaphyseal tibial fractures stabilized using minimally invasive plate osteosynthesis (MIPO). STUDY DESIGN: Prospective clinical trial. SAMPLE POPULATION: Fifteen client owned dogs. METHODS: Virtual 3D models of both pelvic limbs were created. Pin guides were designed to conform to the proximal and distal tibia. A reduction bridge was designed to align the pin guides based on the guides' spatial location. Guides were 3D printed, sterilized, and applied, in conjunction with transient application of a circular fixator, to facilitate indirect fracture realignment before plate application. Alignment of the stabilized tibiae was assessed using postoperative computed tomography scans. RESULTS: Mean duration required for virtual planning was 2.5 h and a mean of 50.7 h elapsed between presentation and surgery. Guide placement was accurate with minor median discrepancies in translation and frontal, sagittal, and axial plane positioning of 2.9 mm, 3.6°, 2.7°, and 6.8°, respectively. Application of the reduction system restored mean tibial length and frontal, sagittal, and axial alignment within 1.7 mm, 1.9°, 1.7°, and 4.5°, respectively, of the contralateral tibia. CONCLUSION: Design and fabrication of a 3D-printed, patient-specific fracture reduction system is feasible in a relevant clinical timeline. Intraoperative pin-guide placement was reasonably accurate with minor discrepancies compared to the virtual plan. Custom 3D-printed reduction system application facilitated near-anatomic or acceptable fracture reduction in all dogs. CLINICAL SIGNIFICANCE: Virtual planning and fabrication of a 3D-printing patient-specific fracture reduction system is practical and facilitated acceptable, if not near-anatomic, fracture alignment during MIPO.

RESUMO

BACKGROUND/OBJECTIVES: Actinic keratoses (AK) are premalignant skin lesions caused by chronic sun exposure, topically managed by 5-fluorouracil (5-FU), diclofenac 3% gel, and imiquimod. Despite their effectiveness, long treatment duration and severe adverse local skin reactions have limited patient concordance. Calcipotriol has recently been used as a combination agent for existing topical AK treatments. A systematic review was performed to determine the clinical efficacy of 5-FU and calcipotriol for the treatment of AK, Bowen's disease, and squamous cell carcinoma (SCC). METHODS: A systematic literature search was conducted on Medline, Embase, and Cochrane Library. Among the 84 records screened, 12 were retrieved for full-text review and 8 were included in the final analysis. RESULTS: Among the 8 studies, there were 214 control patients and 288 patients who received the intervention. The combination 5% 5-FU with calcipotriol resulted in a significant reduction in the number of AKs on the face, scalp, right upper extremity, and left upper extremity for all sites at 8 weeks (P < .0001). No significant difference in SCC incidence was observed at 1 or 2 years, but there was a significant reduction observed at 3 years for SCC on face and scalp. No study assessed the combination for Bowen's disease. CONCLUSIONS: Combination 5% 5-FU with calcipotriol is an effective treatment for Aks; however, future trials may consider longer treatment and follow-up periods for the treatment and prevention of AK, SCC in situ, and SCC.

RESUMO

In the US, <20% of cancers are diagnosed by standard-of-care (SoC) screening. Multicancer early detection (MCED) tests offer the opportunity to expand cancer screening. Understanding the characteristics and clinical outcomes of MCED-detected cancers is critical to clarifying MCED tests' potential impact. DETECT-A is the first prospective interventional trial of an MCED blood test (CancerSEEK). CancerSEEK, coupled with diagnostic PET-CT, identified cancers including those not detected by SoC screening, the majority of which were localized or regional. We report multiyear outcomes in patients with cancers diagnosed following a positive CancerSEEK test. Nine cancer types were diagnosed in 26 participants whose cancers were first detected by CancerSEEK. Information on cancer diagnoses, treatments, and clinical outcomes was extracted from medical records through November 2022. Data collection occurred at a median of 4.4 years (IQR: 4.1-4.6) following study enrollment. Thirteen of 26 (50%) participants were alive and cancer-free [ovarian (4), thyroid (1), uterine (2), breast (1), colorectal (2), and lung (3)]; 7/13 (54%) had cancers without recommended SoC screening modalities. All eight treated stage I or II participants (8/8, 100%) and 12/14 (86%) surgically treated participants were alive and cancer-free. Eligibility for surgical treatment was associated with favorable multiyear outcomes (P = 0.0002). Half of participants with MCED-detected cancers were alive and cancer-free after 4.4 years median follow-up. Most were diagnosed with early-stage cancers and were treated surgically. These results suggest that early cancer detection by CancerSEEK may have facilitated curative-intent treatments and associated positive clinical outcomes in some DETECT-A participants. Prevention Relevance: This study provides preliminary evidence of the potential of multicancer early detection testing as an effective screening tool for detecting cancers without standard-of-care (SoC) screening modalities and complementing SoC cancer screening.

RESUMO

This study is to report the demographics, incidence, and patterns of spinal injuries associated with border crossings resulting from a fall from a significant height. A retrospective cohort study was performed at a Level I trauma center from January 2016 to December 2021 to identify all patients who fell from a significant height while traversing the U.S.-Mexico border and were subsequently admitted. A total of 448 patients were identified. Of the 448 patients, 117 (26.2%) had spine injuries and 39 (33.3%) underwent operative fixation. Females had a significantly higher incidence of spine injuries (60% vs. 40%; p < 0.00330). Patients with a spine fracture fell from a higher median fall height (6.1 vs. 4.6 m; p < 0.001), which resulted in longer median length of stay (LOS; 12 vs. 7 days; p < 0.001), greater median Injury Severity Score (ISS; 20 vs. 9; p < 0.001), and greater relative risk (RR) of ISS >15 (RR = 3.2; p < 0.001). Patients with operative spine injuries had significantly longer median intensive care unit (ICU) LOS than patients with non-operative spine injuries (4 vs. 2 days; p < 0.001). Patients with spinal cord injuries and ISS >15 sustained falls from a higher distance (median 6.1 vs. 5.5 m) and had a longer length of ICU stay (median 3 vs. 0 days). All patients with operative spine injuries had an ISS >15 relative to 50% of patients with non-operative spine injuries (median ISS 20 vs. 15; p < 0.001). Patients with spine trauma requiring surgery had a higher incidence of head (RR = 3.5; p 0.0353) and chest injuries (RR = 6.0; p = 0.0238), but a lower incidence of lower extremity injuries (RR = 0.5; p < 0.001). Thoracolumbar injuries occurred in 68.4% of all patients with spine injuries. Patients with operative spine injuries had a higher incidence of burst fracture (RR = 15.5; p < 0.001) and flexion-distraction injury (RR = 25.7; p = 0.0257). All patients with non-operative spine injuries had American Spinal Injury Association (ASIA) D or E presentations, and patients with operative spine injuries had a higher incidence of spinal cord injury: ASIA D or lower at time of presentation (RR = 6.3; p < 0.001). Falls from walls in border crossings result in significant injuries to the head, spine, long bones, and body, resulting in polytrauma casualties. Falls from higher height were associated with a higher frequency and severity of spinal injuries, greater ISS, and longer ICU length of stay. Operative spine injuries, compared with non-operative spine injuries, had longer ICU length of stay, greater ISS, and different fracture morphology. Spine surgeons and neurocritical care teams should be prepared to care for injuries associated with falls from height in this unique population.
