RESUMEN

PURPOSE: Pelvic organ prolapse (POP) and overactive bladder (OAB) commonly affect the aging female population. We aimed to investigate the possible relationship between the two, as reflected by urodynamic studies. METHODS: A retrospective analysis was conducted on women who underwent urodynamic studies at a university-affiliated tertiary medical center from January 2018 to January 2021. Women presenting with urge incontinence and diagnosed with detrusor overactivity (DO) were included in the study. Based on the presence or absence of a modified POP-Q ≥ grade 2, these women were categorized into two groups. Data on general demographics, clinical symptoms, and urodynamic findings were extracted and compared using SPSS. RESULTS: During the study period, 949 urodynamic evaluations were performed. Of these, 303 (31.92%) reported urge incontinence. Out of this subset, 151 (49.83%) were diagnosed with DO. Within this group, 18 (11.9%) had POP, while 134 (88.1%) did not. The POP group had a notably higher incidence of prior vaginal hysterectomy and anterior colporrhaphy (p = 0.02 and p = 0.01, respectively). While most urodynamic parameters were similar between groups, there was a significant increase in hesitancy in the POP group (13 s vs 8 s, p = 0.03). There was a trend indicating a reduced median Q max (12 ml/s vs. 18 ml/s, p = 0.06) and an increased flow time (55 s vs 40 s, p = 0.08) in the POP group. CONCLUSION: The urodynamic profile of the POP group suggests an obstructive voiding pattern. Further longitudinal research is essential to fully understand the relationship between POP and OAB.

RESUMEN

BACKGROUND: The interdependence of cytokines and appetite-modifying hormones implicated in cancer anorexia-cachexia syndrome (CACS) remains unclear. This study aimed to regroup these cytokines and hormones into distinct inflammatory (or non-inflammatory) pathways and determine whether these pathways can classify patients with CACS phenotypes. METHODS: Clinical characteristics of 133 patients [61.7% male; mean age = 63.4 (SD: 13.1) years] with advanced cancer prior to oncology treatments were documented, including weight loss history. Patients completed the Functional Assessment of Anorexia-Cachexia Therapy (FAACT) questionnaire and Timed Up and Go test and had their sex-standardized skeletal muscle index (z-SMI) and fat mass index (z-FMI) derived using computed tomography scans. Their plasma levels of cytokines and appetite-modifying hormones were also determined. Date of death was recorded. Exploratory factor analysis (EFA) was used to regroup 15 cytokines and hormone into distinct inflammatory pathways (factors). For each patient, regression factor scores (RFS), which tell how strongly the patient associates with each factor, were derived. Two-step cluster analysis on the RFS was used to classify patients into groups. CACS phenotypes were correlated with RFS and compared between groups. Groups' survival was estimated using Kaplan-Meier analysis. RESULTS: Patients had low z-SMI (mean = -3.78 cm2 /m2 ; SD: 8.88) and z-FMI (mean = 0.08 kg2 /m2 ; SD: 56.25), and 62 (46.6%) had cachexia. EFA identified three factors: (F-1) IFN-γ, IL-1ß, Il-4, IL-6, IL-10, IL-12, TGFß1 (positive contribution), and IL-18 (negative); (F-2) IL-8, IL-18, MCP-1, TGFß1, TNF-α (positive), and ghrelin (negative); and (F-3) TRAIL and leptin (positive), and TGFß1 and adiponectin (negative). RFS-1 was associated with cachexia (P = 0.002); RFS-2, with higher CRP (P < 0.0001) and decreased physical function (P = 0.01); and RFS-3 with better appetite (P = 0.04), lower CRP (P = 0.002), higher z-SMI (P = 0.04) and z-FMI (P < 0.0001), and less cachexia characteristics (all P < 0.001). Four patient groups were identified with specific RFS clusters aligning with the CACS continuum from no cachexia to pre-cachexia, cachexia, and terminal cachexia. Compared to the other two groups, groups 1 and 2 had higher plasma levels of IL-18 and TRAIL. Group 1 also had lower inflammatory cytokines, adiponectin, and CRP compared to the other three groups. Group 3 had inflammatory cytokine levels similar to group 2, except for TNF-α and leptin which were lower. Group 4 had very high inflammatory cytokines, adiponectin, and CRP compared to the other 3 groups (all P < 0.0001). Groups 3 and 4 had worse cachexia characteristics (P < 0.05) and shorter survival (log rank: P = 0.0009) than the other two groups. CONCLUSIONS: This exploratory study identified three distinct pathways of inflammation, or lack thereof, characterizing different CACS phenotypes.

RESUMEN

Adults who have had obesity from childhood are at greater risk of obesity-related comorbidities compared to those who only develop obesity in adulthood. The main way of mitigating these risks in obesity is with weight loss, which has been shown to positively affect the cardiorespiratory fitness (CRF) and body composition of adults. However, it is unclear whether the response of these outcomes to weight loss may be influenced by age of obesity onset. The objective of our study was to investigate how age of obesity onset mitigates the responsiveness of CRF, muscle strength and body composition to modest weight loss. Measurements were conducted at baseline and 12 weeks. In total, 37 participants (childhood-onset = 19, adult-onset = 18) lost 3.7% ± 0.4% through aerobic exercise and diet. The YMCA cycle ergometer test (YMCA) and the 20-m shuttle run test (20MSR) were used to estimate CRF (mL kg-1 min-1 ) and a handgrip dynamometer was used to estimate muscle strength. Total body composition was assessed by dual-energy x-ray absorptiometry (DEXA). Overall, CRF and body composition improved (time effect: p < 0.05) after 12 weeks. There was no group-by-time interaction for YMCA, 20MSR, muscle strength and body composition variables. Therefore, the present study suggests that individuals with childhood-onset obesity and adult-onset obesity can improve their CRF and body composition similarly after mild weight loss.

RESUMEN

BACKGROUND: Malnutrition in children and young adults undergoing blood and marrow transplantation (BMT) increases morbidity and mortality. Addressing this via optimization of enteral nutrition can potentially improve outcomes. METHODS: This Quality Improvement project utilized pre-post-intervention design and post-intervention survey to evaluate a novel program optimizing enteral nutrition support in children undergoing BMT. All patients aged 0-18 who were admitted during the 16-week implementation period followed the Enteral Nutrition Optimization Program from pre-BMT through discharge. Data on biometric indicators, complications, and post-transplant milestone time markers were evaluated via Mann-Whitney U, Fisher's exact, and Chi-square tests as indicated using SPSS™ Version 27. A separate sample of clinical providers completed a post-intervention survey to evaluate the feasibility and acceptance of the intervention. FINDINGS: Six patients received the intervention, with 12 patients evaluated. There were no statistical differences between groups on measured evaluations of weight loss (0.15 kg vs +0.4 kg, p = 0.39), malnutrition (2 vs 3, p = 0.545), graft-versus-host-disease (2 vs 2, p = 1), time to engraftment (platelets day 22 vs 20.5, p = 0.589), infections (p = 0.368), and length of stay (32.5 days vs 31 days, p = 1). The provider sample of 45 participants showed overall feasibility and acceptance of the intervention (88.9% agreed or strongly agreed). DISCUSSION: Feasibility and acceptance were high, resulting in increased use of nasogastric and gastrostomy tubes. Though no clinical significance, interpretation is limited due to the small sample size. PRACTICE IMPLICATIONS: Implementing a novel nutritional support program resulted in a culture shift towards enteral nutrition optimization. Further studies are needed to determine clinical impacts.

RESUMEN

BACKGROUND: Direct observation is important, yet medical residents are rarely observed. We implemented and evaluated a direct observation program in resident clinics to increase the frequency of observation and feedback and improve perceptions about direct observation. METHODS: We assigned faculty as observers in our resident clinics between June 2019 and February 2020. We surveyed residents and faculty before and after the program. Faculty completed a form for each observation performed. We analyzed surveys to examine changes in barriers, frequency and type of observations and feedback, and attitudes toward observation. The analytical sample included 38 and 37 pre- and postresident surveys, respectively, and 20 and 25 pre- and postfaculty surveys, respectively. RESULTS: Resident survey response rates were 32.3% (40/124) pre- and 30.7% (39/127) postintervention. Most residents (76% [pre], 86% [post], P = 0.258) reported being observed in at least one of the four areas: history, examination, counseling, or wrap-up. We received observation tracking forms on 68% of eligible residents. Observed history taking increased from 30% to 79% after the program (P = 0.0010). Survey response rates for faculty were 64.7% (22/34) pre- and 67.5% (25/37) postintervention. Fewer faculty reported time (80% [pre], 52% [post], P = 0.051) and competing demands (65% [pre], 52% [post], P = 0.380) as barriers postintervention. Fewer faculty postintervention viewed observation as a valuable teaching tool (100% [pre], 79% [post], P = 0.0534). All faculty who did not view observation as valuable were the least experienced. DISCUSSION: Assigning faculty as observers can increase observation, especially in history taking, though data suggest an increase in negative perceptions of observation by faculty.

RESUMEN

Background: Valuable research requires contribution from many experts; however, the "et al." truncation often keeps all individuals from being acknowledged. The adoption of a new citation rule (list all authors up to 30, followed by et al.) would allow more authors to be acknowledged. The purpose of this study was to (1) explore the citation styles of the top 10 Plastic Surgery, Surgery, and Medical journals and (2) compare the number of extra pages required, and the number of additional authors acknowledged when the "new rule" is implemented. Methods: The top 10 journals in Plastic Surgery, Surgery, and Medicine were identified. The citation styles used in each of the journals were reviewed and the reference list from a recently published article was extracted. The original reference list was used to create an Extended Reference List using the new rule. Results: Most journals implemented "et al." when seven or more authors were listed. Ten articles required additional pages to accommodate the Extended Reference List. When the "et al." truncation was introduced after 30 authors, there was an almost 100% chance of all authors being included. The adoption of this rule rarely resulted in the need for additional pages, especially within Plastic Surgery. Conclusions: In a time of electronic publishing, where constraints such as article and journal page length should not be important factors, all authors should be recognized. The use of the "et al." truncation should be discouraged by all individuals involved in the production and publication of research. Scenario You are asked by the Editor-in-Chief of your specialty's journal to review an article in your area of expertise. You gladly accept the task. One of the questions you are required to answer in your review is whether the authors of the submitted manuscript have missed any important articles in their references. As you are the recognized expert in this field, you glance at the references to see if a key article you published 3 years earlier has been included. The first author of that article was a junior resident in your service and the research was done under your supervision. To their credit, the authors included the said article, but you are dismayed that the reference does not include your name. It includes only the names of the first three authors, all junior residents in your service. Your name, and the names of many others, are lost in the et al. truncation.


Contexte: Une recherche intéressante nécessite la contribution de nombreux experts; cependant, le raccourci « et coll. ¼ empêche souvent la reconnaissance de toutes les personnes. L'adoption d'une nouvelle règle de référencement (énumérer tous les auteurs jusqu'à 30, suivi de et coll.) permettrait de reconnaître davantage d'auteurs. L'objectif de cette étude était de 1) explorer les styles de référence des 10 principaux journaux de chirurgie plastique, chirurgie et médecine, et 2) comparer le nombre de pages supplémentaires requises et le nombre d'auteurs supplémentaires identifiés quand la « nouvelle règle ¼ est appliquée. Méthodes: Les 10 principaux journaux de chirurgie plastique, chirurgie et médecine ont été identifiés. Les styles de référencement utilisés dans chacun de ces journaux ont été revus et la liste des références d'un article récemment publié a été extraite. La liste de références originale a servi à créer une liste de références étendue selon la nouvelle règle. Résultats: La majorité des journaux a utilisé « et coll. ¼ quand 7 auteurs ou plus étaient cités. Dix articles ont nécessité des pages supplémentaires pour accueillir la liste de références étendue. Quand le raccourci « et coll. ¼ était introduit avec le seuil de 30 auteurs, il y avait pratiquement 100 % de chances d'avoir inclus tous les auteurs. L'adoption de cette règle a rarement entraîné le besoin de pages supplémentaires, en particulier dans Plastic Surgery. Conclusions: À l'époque de l'édition électronique où des contraintes telles que la longueur d'un article et le nombre de pages ne devraient pas être des facteurs importants, tous les auteurs devraient être reconnus. L'utilisation du raccourci « et coll. ¼ devrait être découragée par tous ceux qui sont impliqués dans la production et la publication de recherches.

RESUMEN

Amputation is an irreversible, last-line treatment indicated for a multitude of medical problems. Delaying amputation in favor of limb-sparing treatment may lead to increased risk of morbidity and mortality. This systematic review aims to synthesize the literature on how ML is being applied to predict amputation as an outcome. OVID Embase, OVID Medline, ACM Digital Library, Scopus, Web of Science, and IEEE Xplore were searched from inception to March 5, 2023. 1376 studies were screened; 15 articles were included. In the diabetic population, models ranged from sub-optimal to excellent performance (AUC: 0.6-0.94). In trauma patients, models had strong to excellent performance (AUC: 0.88-0.95). In patients who received amputation secondary to other etiologies (e.g.: burns and peripheral vascular disease), models had similar performance (AUC: 0.81-1.0). Many studies were found to have a high PROBAST risk of bias, most often due to small sample sizes. In conclusion, multiple machine learning models have been successfully developed that have the potential to be superior to traditional modeling techniques and prospective clinical judgment in predicting amputation. Further research is needed to overcome the limitations of current studies and to bring applicability to a clinical setting.

RESUMEN

Purpose: There is a lack of scientific consensus on the best arthroplasty implant option for proximal interphalangeal joint (PIPJ) arthritis, due to diversity in outcome reporting and measurement methods. The development of a standardized core outcome set (COS) and standard outcome measures could mitigate this issue. This study catalogs the reported outcomes and outcome measures found in PIPJ arthroplasty studies, which can be used in the first step of developing a COS. Methods: A database search of MEDLINE, EMBASE, and Web of Science (January 1, 2010, to March 10, 2021) was performed to retrieve studies that reported outcomes of the 3 most common primary PIPJ arthroplasty implants: silicone, pyrocarbon, and metal-polyethylene. The primary objectives of this study include reported outcomes and outcome measures. Secondary objectives include clinimetric properties of outcome measures, study design, and implant types. Results: Fifty articles met inclusion criteria. Of the included studies, 41 (82%) were case series, 8 (16%) were cohort studies, and 1 (2%) was a randomized control trial. Thirty-three unique outcomes were identified. Fifteen (46%) outcomes were clinician-reported and 26 (79%) were patient-reported. Eighteen unique outcome measures were identified. Of the outcome measures, 15 (83%) were patient-reported, 1 (6%) was clinician-reported, and 2 (11%) were reported by both patients and clinicians. Conclusions: Substantial heterogeneity was found in reported outcomes and outcome measures across studies evaluating PIPJ arthroplasty, impeding knowledge translation. The development of a COS for PIPJ arthroplasty is necessary to help compare and pool data across studies, and advance scientific knowledge.


Objectif: Il manque de consensus scientifique sur la meilleure option d'arthroplastie pour l'arthrite de l'articulation interphalangienne proximale (IPP) en raison de la diversité des résultats décrits et des méthodes de mesure. L'élaboration d'un ensemble standardisé de résultats de base et de mesures standardisées des résultats pourrait contribuer à limiter ce problème. Cette étude dresse un catalogue des résultats rapportés et des mesures de résultats trouvés dans les études sur l'arthroplastie des IPP; celui-ci peut servir de première étape à l'élaboration d'un ensemble standardisé de résultats de base. Méthodes: Une recherche a été menée dans les bases de données MEDLINE, EMBASE et Web of Science sur la période du 1er janvier 2010 au 10 mars 2021 pour extraire les études qui rapportaient des résultats avec les 3 implants pour arthroplastie des IPP les plus souvent utilisés : silicone, pyrocarbone et métal-polyéthylène. Les objectifs principaux de cette étude incluent les résultats rapportés et les mesures des résultats. Les objectifs secondaires sont, notamment, les propriétés clinimétriques des mesures des résultats, la conception des études et les types d'implants. Résultats: Cinquante articles satisfaisaient les critères d'inclusion. Parmi les études incluses, 41 (82%) étaient des séries de cas, 8 (16%) étaient des études de cohortes et 1 (2%) était un essai randomisé. Trente-trois résultats uniques ont été identifiés. Quinze résultats (46%) étaient rapportés par le clinicien et 26 (79%) ont été déclarés par les patients. Dix-huit mesures uniques de résultats ont été identifiées. Parmi les mesures de résultats, 15 (83%) ont été déclarées par les patients, 1 (6%) a été déclarée par un clinicien et 2 (11%) ont été déclarées à la fois par les patients et les cliniciens. Conclusions: Une hétérogénéité importante a été constatée dans les résultats rapportés et dans les mesures de résultats dans les études évaluant l'arthroplastie des IPP, entravant leur traduction en connaissances utiles. L'élaboration d'un ensemble standardisé de résultats de base s pour les IPP est nécessaire pour comparer et regrouper les données entre les études et donc pour faire avancer les connaissances scientifiques.

RESUMEN

Credible clinical research is a precondition of evidence-based surgery. If clinical research is not conducted and reported properly, such research can be unreliable, unclear, and misleading. Our journal, Plastic Surgery, aims to improve its quality and thus enhance interest, submissions, and readership. To do so, we must ensure that the articles published in our journal align with these goals. This article guides future clinical research contributors, how to design, conduct and report valuable and reliable research. Readers are informed how to choose a title and keywords that properly reflect the content of the article. The proper organization of a manuscript, and the information that goes into each section is described. Valuable tools like the EQUATOR Network Guidelines, the FINER Criteria and the PICOT Format are described for the reader. These resources help formulate a proper research question and ensure transparency in reporting. Commonly used study designs, and the research questions they answer are presented. This ensures that those engaged in research are choosing the right study design for their research. We outline the statistical information that should be presented in the Methods section and differentiate between the content that should be found in the Results and Discussion sections. As Plastic Surgery strives to publish high-quality, reliable research, it is by the standards presented in this article that we will judge all manuscripts submitted for publication.

RESUMEN

Objectives: To identify associations between demographics, social determinants of health, health conditions, and reported history of insomnia. A cross-sectional study including 11,960 adult community members recruited through HealthStreet, a community outreach program at University of Florida. Methods: Health assessments were conducted via interviews. Participants reported their demographic background, level of social support, history of health conditions, and insomnia. Logistic regression was used to understand associations between risk factors and history of insomnia. Results: The prevalence of self-reported insomnia was 27.3%. Adults aged ≥ 65 years (OR = 1.16) and women (OR = 1.18) reported higher rates of insomnia than their counterparts. Black/African American individuals reported lower rates of insomnia (OR = 0.72) than White individuals. Individuals with food insecurity (OR = 1.53), a military history (OR = 1.30), lower social support (OR = 1.24), living alone (OR = 1.14), anxiety (OR = 2.33), cardiometabolic disease (OR = 1.58), and attention-deficit hyperactivity disorder (ADHD) (OR = 1.44) were significantly more likely to endorse insomnia compared with their counterparts. Depression (OR = 2.57) had the strongest association with insomnia. Conclusions: This study provides evidence regarding who is at greater risk for insomnia among a large community-based sample. Our findings highlight the importance of screening for insomnia, particularly among patients who experience food insecurity, are military veterans, have anxiety, depression, ADHD, or cardiometabolic disease, as well as those who live alone or have lower levels of social support. Future public health campaigns should provide education on insomnia symptoms, treatments, and evidenced-based sleep-promotion strategies.

RESUMEN

OBJECTIVE: The aim of this study was to determine the effect of age of obesity onset on senescence-related markers in abdominal (AB) and femoral (FEM) subcutaneous adipose tissue (SAT) before and after moderate (~10%) weight loss. METHODS: AB and FEM SAT were collected from human females with childhood-onset obesity (CO) or adult-onset obesity (AO) before and after diet- and exercise-induced weight loss. Immunofluorescence analysis of γH2AX/RAD51 (DNA damage/repair markers) and p53/p21 (senescence markers) was conducted in cultured preadipocytes, and senescence-associated ß-galactosidase (SA-ß-gal) activity was measured in SAT. RESULTS: CO had proportionately more AB and FEM preadipocytes with DNA damage (γH2AX+ ) and senescence markers (p53+ and/or p21+ ) than AO at baseline. The proportion of γH2AX+ FEM preadipocytes declined with weight loss in CO and was similar between groups after weight loss. The number of γH2AX foci in γH2AX+ preadipocytes decreased similarly between groups and regions with weight loss in parallel with an increase in RAD51. The proportion of p53+ and p21+ preadipocytes and SA-ß-gal+ cells in SAT did not change with weight loss, but the total p21 intensity in p53+ /p21+ FEM preadipocytes declined in AO. CONCLUSIONS: These results provide preliminary evidence that females with CO have an accelerated preadipocyte aging state that improves with weight loss in terms of DNA damage but not senescence.

RESUMEN

HER2 mutations are infrequent genomic events in biliary tract cancers (BTCs). Neratinib, an irreversible, pan-HER, oral tyrosine kinase inhibitor, interferes with constitutive receptor kinase activation and has activity in HER2-mutant tumours. SUMMIT is an open-label, single-arm, multi-cohort, phase 2, 'basket' trial of neratinib in patients with solid tumours harbouring oncogenic HER2 somatic mutations (ClinicalTrials.gov: NCT01953926). The primary objective of the BTC cohort, which is now complete, is first objective response rate (ORR) to neratinib 240 mg orally daily. Secondary objectives include confirmed ORR, clinical benefit rate, progression-free survival, duration of response, overall survival, safety and tolerability. Genomic analyses were exploratory. Among 25 treatment-refractory patients (11 cholangiocarcinoma, 10 gallbladder, 4 ampullary cancers), the ORR is 16% (95% CI 4.5-36.1%). The most common HER2 mutations are S310F (n = 11; 48%) and V777L (n = 4; 17%). Outcomes appear worse for ampullary tumours or those with co-occurring oncogenic TP53 and CDKN2A alterations. Loss of amplified HER2 S310F and acquisition of multiple previously undetected oncogenic co-mutations are identified at progression in one responder. Diarrhoea is the most common adverse event, with any-grade diarrhoea in 14 patients (56%). Although neratinib demonstrates antitumour activity in patients with refractory BTC harbouring HER2 mutations, the primary endpoint was not met and combinations may be explored.

RESUMEN

BACKGROUND: "Spin" refers to a manipulation of language that implies benefit for an intervention when none may exist. Randomized controlled trials (RCTs) in other fields have been demonstrated to employ spin, which can mislead clinicians to use ineffective or unsafe interventions. This study's objective was to determine the strategies, severity, and extent of spin in plastic surgery RCTs with nonsignificant primary outcomes. METHODS: A literature search of the top 15 plastic surgery journals using MEDLINE was performed (2000 through 2020). Parallel 1:1 RCTs with a clearly identified primary outcome showing statistically nonsignificant results ( P > 0.05) were included. Screening, data extraction, and spin analysis were performed by two independent reviewers. The spin analysis was then independently assessed in duplicate by two plastic surgery residents with graduate-level training in clinical epidemiology. RESULTS: From 3497 studies identified, 92 RCTs were included in this study. Spin strategies were identified in 78 RCTs (85%), including 64 abstracts (70%) and 77 main texts (84%). Severity of spin was rated moderate or high in 43 abstract conclusions (47%) and 42 main text conclusions (46%). The most identified spin strategy in the abstract was claiming equivalence for statistically nonsignificant results (26%); in the main text, focusing on another objective (24%). CONCLUSIONS: This study suggests that 85% of statistically nonsignificant RCTs in plastic surgery employ spin. Readers of plastic surgery research should be aware of strategies, whether intentional or unintentional, used to manipulate language in reports of statistically nonsignificant RCTs when applying research findings to clinical practice.

BACKGROUND: Postoperative care after dorsal wrist ganglion (DWG) excision is highly varied. The effect of immobilization of the wrist on patient outcomes has not yet been examined. METHODS: A systematic review of the literature was performed to determine whether wrist immobilization after DWG surgical excision is beneficial. A survey of hand surgeons in Canada was performed to sample existing practice variations in current immobilization protocols after DWG excision. RESULTS: A systematic review yielded 11 studies that rigidly immobilized the wrist (n = 5 open excision, n = 5 arthroscopic excision, n = 1 open or arthroscopic excision), 10 studies that used dressings to partially limit wrist motion (n = 5 open, n = 5 arthroscopic), 1 study (open) that did either of the above, and 2 studies (arthroscopic) that did not restrict wrist motion postoperatively. This ranged from 48 hours to 2 weeks in open DWG excision and 5 days to 3 weeks in arthroscopic DWG excision. The survey of Canadian hand surgeons had a similarly divided result of those who chose to immobilize the wrist fully (41%), partially (14%), or not at all (55%). Most surgeons surveyed who immobilized the wrist postoperatively did so for 1 to 2 weeks. CONCLUSION: The systematic review and survey of Canadian hand surgeons reveal that hand surgeons are divided regarding the need to immobilize the wrist after DWG excision. In terms of functional outcome, there is no compelling data to suggest 1 strategy is superior. The time frame for immobilization when undertaken was short at 2 weeks or less.The systematic review is registered in the PROSPERO database (PROSPERO 2016:CRD42016050877).

RESUMEN

Breast cancer bone metastasis is currently incurable. Evidence suggests that inhibiting IL-1 signalling with the IL1R antagonist, Anakinra, or the IL1ß antibody, Canakinumab, prevents metastasis and almost eliminates breast cancer growth in the bone. However, these drugs increase primary tumour growth. We, therefore, investigated whether targeting other members of the IL-1 pathway (Caspase-1, IL1ß or IRAK1) could reduce bone metastases without increasing tumour growth outside of the bone. Inhibition of IL-1 via MLX01 (IL1ß secretion inhibitor), VRT043198/VX765 (Caspase-1 inhibitor), Pacritinib (IRAK1 inhibitor) or Anakinra (IL1R antagonist) on tumour cell viability, migration and invasion were assessed in mouse mammary E0771 and Py8119 cells in vitro and on primary tumour growth, spontaneous metastasis and metastatic outgrowth in vivo. In vitro, Inhibition of IL-1 signalling by MLX01, VRT043198 and Anakinra reduced migration of E0771 and Py8119 cells and reversed tumour-derived IL1ß induced-increased invasion and migration towards bone cells. In vivo, VX765 and Anakinra significantly reduced spontaneous metastasis and metastatic outgrowth in the bone, whereas MLX01 reduced primary tumour growth and bone metastasis. Pacritinib had no effect on metastasis in vitro or in vivo. Targeting IL-1 signalling with small molecule inhibitors may provide a new therapeutic strategy for breast cancer bone metastasis.

RESUMEN

BACKGROUND: In surgery for Dupuytren disease (DD), palmar fascia specimens are routinely submitted for pathological evaluation. The purpose of this study was to determine the rate of discordant diagnosis and the value of, and costs associated with, routine pathological analysis of palmar fascia tissue extracted in surgery for clinically diagnosed DD. METHODS: All pathology reports for in-house palmar fascia specimens obtained in surgery for clinically diagnosed DD (time period: January 2001 to December 2020) were retrieved from one academic institution. All specimens were classified by a hierarchical free-text string matching algorithm (HFTSMA) and searched for evidence of malignancy. The primary outcome was percentage of concordant, discrepant, and discordant diagnoses. Secondary outcomes included anatomical location and costs. The HFTSMA was used to capture the anatomical location. Costs included professional, laboratory processing, and ancillary fees based on the Ontario Schedule of Benefits. RESULTS: The search retrieved 1323 pathology reports, with 1480 palmar fascia specimens, from 1078 individual patients. By diagnosis, 96.1% of specimens (1422/1480) were concordant (fibromatosis), 3.9% (58/1480) were discrepant (scarring/fibrosis, benign fascia/connective tissue, or other benign findings), and 0% (0/1480) were discordant. The most common location was ring finger (n = 381, 48.7%). Ancillary testing was minimal. The cost per palmar fascia specimen was estimated to be CAD $34.57. The institutional costs were approximately CAD $2558.18/year. CONCLUSIONS: Routine pathological examination of specimens in cases of clinically diagnosed DD does not yield additional clinically important findings and may not warrant their costs.

RESUMEN

Body mass index is poor at distinguishing between adiposity and muscle. Based on dual energy X-ray absorptiometry data, a diagnostic framework to analyze body composition by categorizing fat- and muscle-mass body composition into four phenotypes has been proposed. The objective of this study was to assess the association between body-composition phenotypes with adiposity measures, health behaviours and cardiometabolic risks in a representative U.S. adult population. Data were from NHANES (1999-2006: n = 9867; 2011-2018: n = 10,454). Four phenotypes based on being above/below the 50th percentile of age- and sex- adjusted reference curves of fat-mass and muscle-mass were identified. Multiple linear and logistic regressions were used to assess phenotypes (high [H] or low [L] adiposity [A] or muscle mass [M]) against adiposity measures, health behaviours, cardiometabolic risk, and dietary intake. Low-adiposity/high-muscle (LA-HM) was the referent. Analyses incorporated the complex sampling design and survey weights, and were adjusted for age, sex, race, and education. Compared to the LA-HM reference group, the HA-LM phenotype was less physically active, had higher total and lower high-density lipoprotein cholesterol, and had lower intake of all examined nutrients (all p < 0.01). For the HA-HM phenotype, unfavourable values were detected for all adiposity and cardiometabolic measures compared to the LA-HM phenotype (all p < 0.01). The two high adiposity phenotypes were associated with poorer health behaviours and cardiovascular risk factors, regardless of muscle-mass, but associations differed across the phenotypes. Results further underscores the importance of accounting for both adiposity and muscle mass in measurement and analysis. Further longitudinal investigation is needed.

RESUMEN

Cancer cachexia is a common, debilitating condition with limited therapeutic options. Using an established mouse model of lung cancer, we find that cachexia is characterized by reduced food intake, spontaneous activity, and energy expenditure accompanied by muscle metabolic dysfunction and atrophy. We identify Activin A as a purported driver of cachexia and treat with ActRIIB-Fc, a decoy ligand for TGF-ß/activin family members, together with anamorelin (Ana), a ghrelin receptor agonist, to reverse muscle dysfunction and anorexia, respectively. Ana effectively increases food intake but only the combination of drugs increases lean mass, restores spontaneous activity, and improves overall survival. These beneficial effects are limited to female mice and are dependent on ovarian function. In agreement, high expression of Activin A in human lung adenocarcinoma correlates with unfavorable prognosis only in female patients, despite similar expression levels in both sexes. This study suggests that multimodal, sex-specific, therapies are needed to reverse cachexia.

RESUMEN

Postpartum hypothermia, though rare after spontaneous vaginal delivery, can be life-threatening, warranting efficient workup and intervention. A 14-year-old primigravida developed postpartum hypothermia following spontaneous vaginal delivery. No clear etiology was identified despite extensive workup. Intervention with warmed fluids and application of forced air warming system resolved the hypothermia in less than 24 hours without relapse. Following negative workup, the most likely etiology was administration of chilled intravenous fluids in the setting of acute blood loss of delivery and physiologic vasodilation of pregnancy. This case demonstrates the importance of considering common and unusual causes of postpartum hypothermia and leads to a recommendation for routine postpartum temperature checks and hypothermia protocols that include warmed fluid replacement and a forced air warming system.

RESUMEN

BACKGROUND: Early identification of patients at risk of developing diabetic kidney disease or rapid renal decline is imperative for appropriate patient management, but traditional methods of predicting renal decline are limited. OBJECTIVE: This study evaluated the impact of PromarkerD, a biomarker-based blood test predicting the risk of diabetic kidney disease (DKD) and rapid renal decline. METHODS: Conjoint analysis clarified the importance of PromarkerD and other patient attributes to physician decisions for type 2 diabetes patients. Forty-two patient profiles were generated, with varying levels of albuminuria, estimated glomerular filtration rate (eGFR), blood pressure, hemoglobin A1c (HbA1c), age, and PromarkerD result. A web-based survey asked each physician to make monitoring/treatment decisions about eight randomly selected profiles. Data were analyzed using multivariable logit models. RESULTS: Two hundred three primary care physicians and 197 endocrinologists completed the survey. PromarkerD result was most important for increasing the frequency of risk factor monitoring. PromarkerD was second to HbA1c in importance for deciding to prescribe sodium/glucose cotransporter-2 inhibitors (SGLT2s) with a DKD indication, second to blood pressure for increasing the dose of lisinopril, and second to eGFR for replacing ibuprofen with a non-nephrotoxic medication. Compared with no PromarkerD results, a high-risk PromarkerD result was associated with significantly higher odds of increasing monitoring frequency (odds ratio [OR]: 2.56, 95% confidence interval: 1.90-3.45), prescribing SGLT2s (OR: 1.98 [1.56-2.52]), increasing lisinopril dose (OR: 1.48 [1.17-1.87]), and replacing ibuprofen (OR: 1.78 [1.32-2.40]). A low-risk PromarkerD result was associated with significantly lower odds of increasing monitoring frequency (OR: 0.48 [0.37-0.64]), prescribing SGLT2s (OR: 0.70 [0.56-0.88]), and replacing ibuprofen (OR: 0.75 [0.57-0.99]). CONCLUSION: PromarkerD could increase adoption of renoprotective interventions in patients at high risk for renal decline and lower the likelihood of aggressive treatment in those at low risk. Further studies are needed to assess patient outcomes with PromarkerD in real-world practice.
