Background: To determine whether -148 C/T fibrinogen gene promoter polymorphism increases stroke risk by modifying the fibrinogen level.Design: A case-control study of patients with first ever ischaemic stroke, confirmed by computed tomography.Methods: Venous blood samples were collected for fibrinogen and routine coagulation tests one week after the stroke, and after three months in about half the patients. Population controls were age and sex matched. -148 C/T fibrinogen polymorphism was determined by polymerase chain reaction followed by digestion with restriction enzymes HindIII/AluI.Results: There were 124 patients and 125 controls, mean age 56 years (range 18 to 75); 34 patients (27%) and 41 controls (33%) were heterozygous for -148 C/T fibrinogen polymorphism; six patients (5%) and five controls (4%) had the T/T genotype. The odds ratio of ischaemic stroke associated with CC homozygotes v T carriers was 0.8 (95% confidence interval, 0.5 to 1.4). Relative risk for ischaemic stroke associated with fibrinogen levels in the highest quartile was 3.9 (1.9 to 8.4) at one week, decreasing to 1.4 (0.6 to 3.3) at three months.Conclusions: -148 C/T fibrinogen gene polymorphism was not a strong risk factor for ischaemic stroke. High fibrinogen levels early after acute stroke probably represent an acute phase response. [ABSTRACT FROM AUTHOR]

Background: This study investigates the potential influence of genotype and parent-of-origin effects (POE) on the clinical manifestations of Lynch syndrome (LS) within families carrying (likely) disease-causing MSH6 germline variants., Patients and Methods: A cohort of 1615 MSH6 variant carriers (310 LS families) was analyzed. Participants were categorized based on RNA expression and parental inheritance of the variant. Hazard ratios (HRs) were calculated using weighted Cox regression, considering external information to address ascertainment bias. The findings were cross-validated using the Prospective Lynch Syndrome Database (PLSD) for endometrial cancer (EC)., Results: No significant association was observed between genotype and colorectal cancer (CRC) risk (HR = 1.06, 95% confidence interval [CI]: 0.77-1.46). Patients lacking expected RNA expression exhibited a reduced risk of EC (Reference Cohort 1: HR = 0.68, 95% CI: 0.43-1.03; Reference Cohort 2: HR = 0.63, 95% CI: 0.46-0.87). However, these results could not be confirmed in the PLSD. Moreover, no association was found between POE and CRC risk (HR = 0.78, 95% CI: 0.52-1.17) or EC risk (Reference Cohort 1: HR = 0.93, 95% CI: 0.65-1.33; Reference Cohort 2: HR = 0.8, 95% CI: 0.64-1.19)., Discussion and Conclusion: No evidence of POE was detected in MSH6 families. While RNA expression may be linked to varying risks of EC, further investigation is required to explore this observation., (© 2024 The Authors.

Introduction: Seroma is a frequent complication that can affect the final result of reconstructive and cosmetic surgeries., Methodology: This study evaluated the effectiveness of 5-Fluorouracil and 75% hypertonic glucose in preventing seroma in a mastectomy rat model, as well as cellular and vascular events in adjacent tissues. A left mastectomy with lymphadenectomy was performed in 60 Wistar-Albino female rats. Animals randomly allocated to the control group (Group I; n = 20) were sutured right after mastectomy. The intervention groups received 1.0 mL of 75% hypertonic glucose (Group II; n = 20) or 1.0 mL of 5-Fluorouracil (Group III; n = 20) at the surgical site before suturing. The assessment of the presence of seroma was performed in all animals at 24, 48, and 72 h and on the 7th and 12th postoperative day. After the 12th day, a tissue sample was taken from the surgical site and sent for histological analysis. The occurrence of seroma was assessed using GEE. A significance level of 5% was adopted., Results: Differences in seroma formation over time were observed for both Control Group I (p=0.041) and Intervention Group II (p<0.001). In Intervention Group III, there was no difference in the percentage and volume of seroma across the assessment points (p=0.627). When both the Control and Intervention Group II were compared to Intervention Group III, we found a reduction in seroma formation in the last group. The reduction in the inflammatory process was more regular to Intervention Group III., Conclusion: In this animal model, 5-Fluorouracil was more effective in preventing seroma formation than 75% Hypertonic Glucose.

Objective: To study the impact of premenopausal risk-reducing salpingo-oophorectomy (RRSO), compared with postmenopausal RRSO, on urinary incontinence (UI) ≥10 years later., Design: Cross-sectional study, nested in a nationwide cohort., Setting: Multicentre in the Netherlands., Population: 750 women (68% BRCA1/2 pathogenic variant carriers) who underwent either premenopausal RRSO (≤45 years, n = 496) or postmenopausal RRSO (≥54 years, n = 254). All participants were ≥55 years at the time of the study., Methods: Urinary incontinence was assessed by the urinary distress inventory-6 (UDI-6); a score ≥33.3 indicated symptomatic UI. The incontinence impact questionnaire short form (IIQ-SF) was used to assess the impact on women's health-related quality of life (HR-QoL). Differences between groups were analysed using regression analyses adjusting for current age and other confounders., Main Outcome Measures: Differences in UDI-6 scores and IIQ-SF scores between women with a premenopausal and a postmenopausal RRSO., Results: Women in the premenopausal RRSO group had slightly higher UDI-6 scores compared with women in the postmenopausal RRSO group (P = 0.053), and their risk of symptomatic UI was non-significantly increased (odds ratio [OR] 2.1, 95% confidence interval [95% CI] 0.93-4.78). A premenopausal RRSO was associated with a higher risk of stress UI (OR 3.5, 95% CI 1.2-10.0) but not with urge UI. The proportions of women with a significant impact of UI on HR-QoL were similar in the premenopausal and postmenopausal RRSO groups (10.4% and 13.0%, respectively; P = 0.46)., Conclusions: More than 15 years after premenopausal RRSO, there were no significant differences in overall symptomatic UI between women with a premenopausal and those with a postmenopausal RRSO., (© 2023 John Wiley & Sons Ltd.)

Aims: The antifungal effect of the yeast species Kluyveromyces marxianus, Meyerozyma caribbica, and Wickerhamomyces anomalus was evaluated against two Fusarium graminearum strains (FRS 26 and FSP 27) in vitro and on corn seeds., Methods and Results: The antifungal effect of the yeasts against F. graminearum was evaluated using scanning electron microscopy and extracellular chitinase and glucanase production to further elucidate the biocontrol mode of action. In addition, the germination percentage and vigor test were investigated after applying yeast on corn seeds. All the yeast strains inhibited fungal growth in vitro (57.4%-100.0%) and on corn seeds (18.9%-87.2%). In co-culture with antagonistic yeasts, F. graminearum showed collapsed hyphae and turgidity loss, which could be related to the ability of yeasts to produce chitinases and glucanases. The three yeasts did not affect the seed corn germination, and W. anomalus and M. caribbica increased corn seed growth parameters (germination percentage, shoot and root length, and shoot dry weight)., Conclusion: Meyerozyma caribbica and W. anomalus showed satisfactory F. graminearum growth inhibition rates and did not affect seed growth parameters. Further studies are required to evaluate the application of these yeasts to the crop in the field., (© The Author(s) 2023.

Diagnosis of Lynch syndrome (LS) caused by a pathogenic germline MSH6 variant may be complicated by discordant immunohistochemistry (IHC) and/or by a microsatellite stable (MSS) phenotype. This study aimed to identify the various causes of the discordant phenotypes of colorectal cancer (CRC) and endometrial cancer (EC) in MSH6-associated LS. Data were collected from Dutch family cancer clinics. Carriers of a (likely) pathogenic MSH6 variant diagnosed with CRC or EC were categorized based on an microsatellite instability (MSI)/IHC test outcome that might fail to result in a diagnosis of LS (eg, retained staining of all 4 mismatch repair proteins, with or without an MSS phenotype, and other staining patterns). When tumor tissue was available, MSI and/or IHC were repeated. Next-generation sequencing (NGS) was performed in cases with discordant staining patterns. Data were obtained from 360 families with 1763 (obligate) carriers. MSH6 variant carriers with CRC or EC (n = 590) were included, consisting of 418 CRCs and 232 ECs. Discordant staining was reported in 77 cases (36% of MSI/IHC results). Twelve patients gave informed consent for further analysis of tumor material. Upon revision, 2 out of 3 MSI/IHC cases were found to be concordant with the MSH6 variant, and NGS showed that 4 discordant IHC results were sporadic rather than LS-associated tumors. In 1 case, somatic events explained the discordant phenotype. The use of reflex IHC mismatch repair testing, the current standard in most Western countries, may lead to the misdiagnosis of germline MSH6 variant carriers. The pathologist should point out that further diagnostics for inheritable colon cancer, including LS, should be considered in case of a strong positive family history. Germline DNA analysis of the mismatch repair genes, preferably as part of a larger gene panel, should therefore be considered in potential LS patients., (Copyright © 2023 The Authors.

Background: This study explores factors associated with transitioning from recent suicidal ideation (SI) to suicide attempt (SA) in depressed outpatients., Methods: This is a case-control study nested in two cohorts (LUEUR and GENESE) of depressed adult outpatients recruited in France and followed up for six weeks. SI, depression, anxiety, insomnia, impulsivity, and hopelessness were assessed with validated scales. Differences between patients with SI who attempted suicide during follow up and those who did not were explored using logistic regressions., Results: There was a slight majority of females in both cohorts. Mean age was 47.2 years in LUEUR and 49.4 years in GENESE. Of the 3785 participants in the LUEUR cohort, 72 (2.1 %) attempted suicide within the 6-week period vs. 19 of the 2698 participants (0.7 %) in the GENESE cohort. In LUEUR, factors associated with SA within the 6-week period were lifetime history of SA (OR = 5.35, 95 % CI = 3.30-8.66), high SI at baseline (OR = 3.87, 95 % CI = 2.4-6.24), associated treatments (OR = 3.28, 95 % CI = 2.00-5.38), and less improvement over follow-up in the following symptoms: SI (OR = 3.64, 95 % CI = 1.89-7.02), depression (OR = 3.66, 95 % CI = 1.76-7.62), and anxiety (OR = 3.26, 95 % CI = 1.46-7.27). In GENESE, associated factors were lifetime history of SAs (OR = 9.93, 95 % CI = 3.83-25.80), and less improvement in SI (OR = 9.20, 95 % CI = 3.61-23.44)., Limitations: Heterogeneity of cohorts prevented from performing a pooled analysis with a greater sample size., Conclusions: In depressed outpatients, lack of improvement was strongly associated with a short-term SA, particularly in patients with a history of previous SAs. Fast acting treatment on SI and depression may help prevent SAs., Competing Interests: Declaration of competing interest None., (Copyright © 2023. Published by Elsevier B.V.)

This paper describes protocols and experiences from a seven-year natural-experiment study in El Paso, Texas, a border city of predominantly Latino/Hispanic population. The study focuses on how Bus Rapid Transit (BRT) impacts physical activity and thus plays a role in alleviating obesity and related chronic diseases that impact healthy aging. Our protocols describe a longitudinal and case-comparison study, which compared residents exposed to new BRT stations with those who were not. This paper also introduces lessons and experiences to overcome the following challenges: delays in the BRT opening (the main intervention), the COVID-19 pandemic, methodological challenges, participant recruitment and retention, and predatory survey takers. Our transdisciplinary approach was pivotal in addressing these challenges. We also proposed and tested multi-level intervention strategies to reduce modifiable barriers to transit use. Our most important takeaway for researchers, practitioners, and policy makers is the importance of being flexible and ready to adapt to new circumstances. Future natural-experiment researchers need to become more versatile in an increasingly volatile and uncertain world., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Li, Lee, Zhong, Xu, Towne, Zhu, Lee, Wang, Aldrete, Garcia, Whigham, Toney, Ibarra and Ory.)

Objective: To examine the effect of a premenopausal risk-reducing salpingo-oophorectomy (RRSO) in women at increased risk of ovarian cancer on objective and subjective cognition at least 10 years after RRSO., Design: A cross-sectional study with prospective follow-up, nested in a nationwide cohort., Setting: Multicentre in the Netherlands., Population or Sample: 641 women (66% BRCA1/2 pathogenic variant carriers) who underwent either a premenopausal RRSO ≤ age 45 (n = 436) or a postmenopausal RRSO ≥ age 54 (n = 205). All participants were older than 55 years at recruitment., Methods: Participants completed an online cognitive test battery and a questionnaire on subjective cognition. We used multivariable regression analyses, adjusting for age, education, breast cancer, hormone replacement therapy, cardiovascular risk factors and depression., Main Outcome Measures: The influence of RRSO on objective and subjective cognition of women with a premenopausal RRSO compared with women with a postmenopausal RRSO., Results: After adjustment, women with a premenopausal RRSO (mean time since RRSO 18.2 years) performed similarly on objective cognitive tests compared with women with a postmenopausal RRSO (mean time since RRSO 11.9 years). However, they more frequently reported problems with reasoning (odds ratio [OR] 1.8, 95% confidence interval [95% CI] 1.1-3.1) and multitasking (OR 1.9, 95% CI 1.1-3.4) than women with a postmenopausal RRSO. This difference between groups disappeared in an analysis restricted to women of comparable ages (60-70 years)., Conclusions: Reassuringly, approximately 18 years after RRSO, we found no association between premenopausal RRSO and objective cognition., (© 2023 John Wiley & Sons Ltd.)

FANCM germline protein truncating variants (PTVs) are moderate-risk factors for ER-negative breast cancer. We previously described the spectrum of FANCM PTVs in 114 European breast cancer cases. In the present, larger cohort, we report the spectrum and frequency of four common and 62 rare FANCM PTVs found in 274 carriers detected among 44,803 breast cancer cases. We confirmed that p.Gln1701* was the most common PTV in Northern Europe with lower frequencies in Southern Europe. In contrast, p.Gly1906Alafs*12 was the most common PTV in Southern Europe with decreasing frequencies in Central and Northern Europe. We verified that p.Arg658* was prevalent in Central Europe and had highest frequencies in Eastern Europe. We also confirmed that the fourth most common PTV, p.Gln498Thrfs*7, might be a founder variant from Lithuania. Based on the frequency distribution of the carriers of rare PTVs, we showed that the FANCM PTVs spectra in Southwestern and Central Europe were much more heterogeneous than those from Northeastern Europe. These findings will inform the development of more efficient FANCM genetic testing strategies for breast cancer cases from specific European populations.

Purpose: To investigate the prevalence of and clinical factors associated with high-grade serous carcinoma (HGSC) at risk-reducing salpingo-oophorectomy (RRSO) in asymptomatic BRCA1/2 -pathogenic variant (PV) carriers., Patients and Methods: We included BRCA1/2 -PV carriers who underwent RRSO between 1995 and 2018 from the Hereditary Breast and Ovarian cancer in the Netherlands study. All pathology reports were screened, and histopathology reviews were performed for RRSO specimens with epithelial abnormalities or where HGSC developed after normal RRSO. We then compared clinical characteristics, including parity and oral contraceptive pill (OCP) use, for women with and without HGSC at RRSO., Results: Of the 2,557 included women, 1,624 had BRCA1 , 930 had BRCA2 , and three had both BRCA1/2 -PV. The median age at RRSO was 43.0 years (range: 25.3-73.8) for BRCA1 -PV and 46.8 years (27.6-77.9) for BRCA2 -PV carriers. Histopathologic review confirmed 28 of 29 HGSCs and two further HGSCs from among 20 apparently normal RRSO specimens. Thus, 24 (1.5%) BRCA1 -PV and 6 (0.6%) BRCA2 -PV carriers had HGSC at RRSO, with the fallopian tube identified as the primary site in 73%. The prevalence of HGSC in women who underwent RRSO at the recommended age was 0.4%. Among BRCA1/2- PV carriers, older age at RRSO increased the risk of HGSC and long-term OCP use was protective., Conclusion: We detected HGSC in 1.5% ( BRCA1 -PV) and 0.6% ( BRCA2 -PV) of RRSO specimens from asymptomatic BRCA1/2 -PV carriers. Consistent with the fallopian tube hypothesis, we found most lesions in the fallopian tube. Our results highlight the importance of timely RRSO with total removal and assessment of the fallopian tubes and show the protective effects of long-term OCP.

Background: Women with a BRCA1/2 pathogenic variant are advised to undergo premenopausal risk-reducing salpingo-oophorectomy after completion of childbearing, to reduce their risk of ovarian cancer. Several studies reported less sexual pleasure 1 to 3 years after a premenopausal oophorectomy. However, the long-term effects of premenopausal oophorectomy on sexual functioning are unknown., Objective: This study aimed to study long-term sexual functioning in women at increased familial risk of breast or ovarian cancer who underwent a risk-reducing salpingo-oophorectomy either before the age of 46 years (premenopausal group) or after the age of 54 years (postmenopausal group). Subgroup analyses were performed in the premenopausal group, comparing early (before the age of 41 years) and later (at ages 41-45 years) premenopausal risk-reducing salpingo-oophorectomy., Study Design: Between 2018 and 2021, 817 women with a high familial risk of breast or ovarian cancer from an ongoing cohort study were invited to participate in our study. Because of a large difference in age in the study between the premenopausal and postmenopausal salpingo-oophorectomy groups, we restricted the comparison of sexual functioning between the groups to 368 women who were 60 to 70 years old at completion of the questionnaire (226 in the premenopausal group and 142 in the postmenopausal group). In 496 women with a premenopausal risk-reducing salpingo-oophorectomy, we compared the sexual functioning between women in the early premenopausal group (n=151) and women in the later premenopausal group (n=345). Differences between groups were analyzed using multiple regression analyses, adjusting for current age, breast cancer history, use of hormone replacement therapy, body mass index, chronic medication use (yes or no), and body image., Results: Mean times since risk-reducing salpingo-oophorectomy were 20.6 years in the premenopausal group and 10.6 years in the postmenopausal group (P<.001). The mean age at questionnaire completion was 62.7 years in the premenopausal group, compared with 67.0 years in the postmenopausal group (P<.001). Compared with 48.9% of women in the postmenopausal group, 47.4% of women in the premenopausal group were still sexually active (P=.80). Current sexual pleasure scores were the same for women in the premenopausal group and women in the postmenopausal group (mean pleasure score, 8.6; P=.99). However, women in the premenopausal group more often reported substantial discomfort than women in the postmenopausal group (35.6% vs 20.9%; P=.04). After adjusting for confounders, premenopausal risk-reducing salpingo-oophorectomy was associated with substantially more discomfort during sexual intercourse than postmenopausal risk-reducing salpingo-oophorectomy (odds ratio, 3.1; 95% confidence interval, 1.04-9.4). Moreover, after premenopausal risk-reducing salpingo-oophorectomy, more severe complaints of vaginal dryness were observed (odds ratio, 2.6; 95% confidence interval, 1.4-4.7). Women with a risk-reducing salpingo-oophorectomy before the age of 41 years reported similar pleasure and discomfort scores as women with a risk-reducing salpingo-oophorectomy between ages 41 and 45 years., Conclusion: More than 15 years after premenopausal risk-reducing salpingo-oophorectomy, the proportion of sexually active women was comparable with the proportion of sexually active women with a postmenopausal risk-reducing salpingo-oophorectomy. However, after a premenopausal risk-reducing salpingo-oophorectomy, women experienced more vaginal dryness and more often had substantial sexual discomfort during sexual intercourse. This did not lead to less pleasure with sexual activity., (Copyright © 2022 The Authors. Published by Elsevier Inc. All rights reserved.)

Grocery stores can provide a conducive environment for interventions targeting healthy eating and access to health services, particularly in low-income communities. A wide array of organizations deliver nutrition and related programs in community settings, but rarely in a coordinated fashion. Collaboration of local health promotion organizations with grocery stores could increase consumers' access to and selection of healthy foods and related services. This evaluation of the In-Store Programming and Outreach Coalition (IPOC) uses thematic analysis of first-person accounts from coalition members. To our knowledge, this is the first study of such a coalition. We present perspectives from six stakeholders about the IPOC strengths, challenges, and recommendations for strengthening the delivery of in-store interventions. Themes identified include partnership, increased client reach and cross-referrals, conflicting work schedules, leadership, and recommendations to identify coalition leaders and expand services to other grocery stores. We conclude that grocery stores can offer a suitable setting for programming and community outreach through coalitions.

Joint stiffness is the most common complication in elbow injuries, presenting several etiologies and pathophysiological mechanisms that hinder treatment and prognosis. Prevention and treatment of joint contracture depend on the cause of stiffness, and early intervention should modify its outcomes. The methods used may be conservative or surgical, alone or in combination, according to each individual situation., Objective: Review articles on articulated elbow orthosis for joint stiffness rehabilitation., Methods: A literature review was conducted in journals available at the PubMed, Medline and LILACS databases, using the following Health Science Descriptors (DeCS): orthotic devices; braces; elbow; elbow joint; contracture; joint disorders. It sought to retrieve and analyze studies with the highest level of evidence that have already been conducted on articulated elbow orthosis for joint stiffness rehabilitation., Results: After applying the inclusion and exclusion criteria, four articles were included from PubMed and none from Medline or LILACS. Of the four PubMed articles, two were systematic reviews and two were randomized clinical trials., Conclusion: Articulated elbow orthoses can benefit joint stiffness treatment, improving range of motion and pain, showing superior effect compared to non-articulated plaster orthotics. Level of Evidence III, Systematic Review of Level III Studies., Competing Interests: All authors declare no potential conflict of interest related to this article.

Introduction: Germline BRCA1/2-associated epithelial ovarian cancer has been associated with better progression-free survival and overall survival than sporadic epithelial ovarian cancer, but conclusive data are lacking., Methods: We matched 389 BRCA1-associated and 123 BRCA2-associated epithelial ovarian cancer patients 1:1 to sporadic epithelial ovarian cancer patients on year of birth, year of diagnosis, and FIGO stage (< = IIA/> = IIB). Germline DNA test was performed before or after epithelial ovarian cancer diagnosis. All patients received chemotherapy. We used Cox proportional hazards models to estimate the associations between mutation status (BRCA1 or BRCA2 versus sporadic) and progression-free survival and overall survival. To investigate whether DNA testing after epithelial ovarian cancer diagnosis resulted in survival bias, we performed additional analyses limited to BRCA1/2-associated epithelial ovarian cancer patients with a DNA test result before cancer diagnosis (n = 73 BRCA1; n = 9 BRCA2) and their matched sporadic controls., Results: The median follow-up was 4.4 years (range 0.1-30.1). During the first three years after epithelial ovarian cancer diagnosis, progression-free survival was better for BRCA1 (HR 0.88, 95% CI 0.74-1.04) and BRCA2 (HR 0.58, 95% CI 0.41-0.81) patients than for sporadic patients. Overall survival was better during the first six years after epithelial ovarian cancer for BRCA1 (HR 0.7, 95% CI 0.58-0.84) and BRCA2 (HR 0.41, 95% CI 0.29-0.59) patients. After surviving these years, survival benefits disappeared or were in favor of the sporadic patients., Conclusion: For epithelial ovarian cancer patients who received chemotherapy, we confirmed survival benefit for BRCA1 and BRCA2 germline pathogenic variant carriers. This may indicate higher sensitivity to chemotherapy, both in first line treatment and in the recurrent setting. The observed benefit appears to be limited to a relatively short period after epithelial ovarian cancer diagnosis., Competing Interests: The authors have declared that no competing interests exist.

Methyl gallate (MG) is a plant-derived phenolic compound known to present remarkable anti-inflammatory effect in different experimental models, such as paw oedema, pleurisy, zymosan-induced arthritis and colitis. Herein we investigated the effect of MG in the mice model of antigen-induced arthritis (AIA), a model with complex inflammatory response, driven primally by immune process and that cause bone and cartilage erosion similarly found in rheumatoid arthritis. Arthritis was induced by intra-articular injection of albumin methylated from bovine serum (mBSA) in C57BL/6 male mice previously immunized. The dose-response analysis of MG (0.7-70 mg/kg; p.o) showed that maximum inhibition was reached with the dose of 7 mg/kg on paw oedema and cell infiltration induced by AIA at 7 h. Treatment with MG (7 mg/kg; p.o) or with the positive control, dexamethasone (Dexa, 10 mg/kg, ip) reduced AIA oedema formation, leukocyte infiltration, release of extracellular DNA and cytokine production 7 and 24 h (acute response). Mice treated daily with MG for 7 days showed no significant weight loss or liver and kidney toxicity contrary to dexamethasone that induced some degree of toxicity. Prolonged treatment with MG inhibited the late inflammatory response (28 days) reducing oedema formation, cell infiltration, synovial hyperplasia, pannus formation and cartilage degradation as observed in histopathological analyses. Ultimately, MG reduced bone resorption as evidenced by a decrease in tartrate-resistant acid phosphate (TRAP)-positive cells number in femur histology. Altogether, we demonstrate that MG ameliorates the inflammatory reaction driven primarily by the immune process, suggesting a potential therapeutic application in arthritis treatment., (© 2022.

Solidago chilensis Meyen (Compositae) is a species native to South America (Brazil) popularly known as arnica. In Brazilian popular medicine, inflorescences and rhizomes of this plant have been used since the end of the 19th century to replace the exogenous and hepatotoxic Arnica montana L. in the treatment of edema and inflammatory pathologies. Although the anti-inflammatory activity of S. chilensis is evidenced in the literature, there is a lack of studies with enriched fractions or compounds isolated from it. The objective of the current study was to characterize phytochemically and to evaluate the pharmacological action in vivo and in vitro of the crude extract and the different fractions (hexane, dichloromethane, acetal, butanolic, and aqueous) isolated from the inflorescence of S. chilensis . The inflorescence crude extract (ScIE) and fractions were administered by intraperitoneal route to mice at different doses. In an LPS-induced pleurisy model, inhibition of leukocyte influx was observed for the ScIE and all fractions tested, as compared to controls. Dichloromethane (ScDicF), butanolic (ScButF), and aqueous (ScAquF) were selected for further analysis as they showed the best inhibitory effects in leukocyte migration and inflammatory cytokine and chemokine production: TNF- α , CXCL1/KC, CXCL2/MIP-2, and CCL11/eotaxin-1. In LPS-stimulated J774A.1 cell line, ScIE and the ScDicF exhibited an inhibitory effect on nitric oxide (NO) production and downmodulated the COX-2 expression; ScAquF failed to modulate NO production and COX-2 expression. In phytochemical analysis, HPLC-UV-DAD chromatograms of ScDicF and ScAquF showed the main peaks with UV spectrum characteristics of flavonoids; chlorogenic acid and isoquercetin were the most present phytochemicals identified in the ScAquF, and a high number of n-alkanes was found in ScHexF. Our study was the first to address biological effects and correlate them to phytochemically characterized fractions from inflorescences of S. chilensis ., Competing Interests: The authors declare no conflict of interest., (Copyright © 2021 Thais Morais de Brito et al.)

Background: Endometrial cancer (EC) risk in BReast CAncer gene 1/2 (BRCA1/2) mutation carriers is uncertain; therefore, we assessed this in a large Dutch nationwide cohort study., Methods: We selected 5980 BRCA1/2 (3788 BRCA1, 2151 gBRCA2, 41 both BRCA1/BRCA2) and 8451 non-BRCA1/2 mutation carriers from the Hereditary Breast and Ovarian cancer study, the Netherlands cohort. Follow-up started at the date of the nationwide Dutch Pathology Registry coverage (January 1, 1989) or at the age of 25 years (whichever came last) and ended at date of EC diagnosis, last follow-up, or death (whichever came first). EC risk in BRCA1/2 mutation carriers was compared with 1) the general population, estimating standardized incidence ratios (SIRs) based on Dutch population-based incidence rates; and 2) non-BRCA1/2 mutation carriers, using Cox-regression analyses, expressed as hazard ratio (HR). Statistical tests were 2-sided., Results: Fifty-eight BRCA1/2 and 33 non-BRCA1/2 mutation carriers developed EC over 119 296 and 160 841 person-years, respectively (SIR = 2.83, 95% confidence interval [CI] = 2.18 to 3.65; and HR = 2.37, 95% CI = 1.53 to 3.69, respectively). gBRCA1 mutation carriers showed increased risks for EC overall (SIR = 3.51, 95% CI = 2.61 to 4.72; HR = 2.91, 95% CI = 1.83 to 4.66), serous-like EC (SIR = 12.64, 95% CI = 7.62 to 20.96; HR = 10.48, 95% CI = 2.95 to 37.20), endometrioid EC (SIR = 2.63, 95% CI = 1.80 to 3.83; HR = 2.01, 95% CI = 1.18 to 3.45), and TP53-mutated EC (HR = 15.71, 95% CI = 4.62 to 53.40). For BRCA2 mutation carriers, overall (SIR = 1.70, 95% CI = 1.01 to 2.87) and serous-like EC risks (SIR = 5.11, 95% CI = 1.92 to 13.63) were increased compared with the general population. Absolute risks by 75 years remained low (overall EC = 3.0%; serous-like EC = 1.1%)., Conclusions: BRCA1/2 mutation carriers have a two- to threefold increased risk for EC, with highest risk observed for the rare subgroups of serous-like and p53-abnormal EC in BRCA1 mutation carriers., (© The Author(s) 2021.

Background: BRCA1/2 mutation carriers are recommended to undergo risk-reducing salpingo-oophorectomy (RRSO) at 35 to 45 years of age. RRSO substantially decreases ovarian cancer risk, but at the cost of immediate menopause. Knowledge about the potential adverse effects of premenopausal RRSO, such as increased risk of cardiovascular disease, osteoporosis, cognitive dysfunction, and reduced health-related quality of life (HRQoL), is limited., Objective: The aim of this study is to assess the long-term health effects of premenopausal RRSO on cardiovascular disease, bone health, cognitive functioning, urological complaints, sexual functioning, and HRQoL in women with high familial risk of breast or ovarian cancer., Methods: We will conduct a multicenter cross-sectional study with prospective follow-up, nested in a nationwide cohort of women at high familial risk of breast or ovarian cancer. A total of 500 women who have undergone RRSO before 45 years of age, with a follow-up period of at least 10 years, will be compared with 250 women (frequency matched on current age) who have not undergone RRSO or who have undergone RRSO at over 55 years of age. Participants will complete an online questionnaire on lifestyle, medical history, cardiovascular risk factors, osteoporosis, cognitive function, urological complaints, and HRQoL. A full cardiovascular assessment and assessment of bone mineral density will be performed. Blood samples will be obtained for marker analysis. Cognitive functioning will be assessed objectively with an online neuropsychological test battery., Results: This study was approved by the institutional review board in July 2018. In February 2019, we included our first participant. As of November 2020, we had enrolled 364 participants in our study., Conclusions: Knowledge from this study will contribute to counseling women with a high familial risk of breast/ovarian cancer about the long-term health effects of premenopausal RRSO. The results can also be used to offer health recommendations after RRSO., Trial Registration: ClinicalTrials.gov NCT03835793; https://clinicaltrials.gov/ct2/show/NCT03835793., International Registered Report Identifier (irrid): DERR1-10.2196/24414., (©Lara Terra, Maartje J Hooning, Bernadette A M Heemskerk-Gerritsen, Marc van Beurden, Jeanine E Roeters van Lennep, Helena C van Doorn, Joanne A de Hullu, Constantijne Mom, Eleonora B L van Dorst, Marian J E Mourits, Brigitte F M Slangen, Katja N Gaarenstroom, M Carola Zillikens, Tim Leiner, Lizet van der Kolk, Margriet Collee, Marijke Wevers, Margreet G E M Ausems, Klaartje van Engelen, Lieke PV Berger, Christi J van Asperen, Encarna B Gomez-Garcia, Irma van de Beek, Matti A Rookus, Michael Hauptmann, Eveline M Bleiker, Sanne B Schagen, Neil K Aaronson, Angela H E M Maas, Flora E van Leeuwen.

Background: The number of bariatric surgeries for the treatment of morbid obesity has increased, and there is growing demand for postbariatric abdominoplasty. The aim of this study was to evaluate the impacts of Scarpa's fascia preservation on total drainage volume, time to drain removal, and seroma formation in anchor-line abdominoplasty., Methods: A total of 42 postbariatric patients were randomly assigned to two groups and underwent anchor-line abdominoplasty. Scarpa's fascia was not preserved during abdominoplasty in one group (n = 21) but was preserved in the other group (n = 21). A suction drain was left in place until the drainage volume was less than 30 ml/24 h. Seroma formation was assessed by abdominal ultrasound on the twentieth postoperative day; only fluid collections greater than 30 ml were considered seromas., Results: The time to drain removal was shorter, and the total drainage volume was lower in the fascial preservation group than in the fascial dissection group. However, no difference in the seroma formation rate was observed between the groups., Conclusion: Scarpa's fascia preservation decreased the drainage volume and the time to drain removal but not the rate of seroma formation., Level of Evidence Ii: This journal requires that authors assign a level of evidence to each article.
