RESUMO
RATIONALE: Sex cord-stromal tumors (SCST) are hormonally active and rare. The aim was to describe their endocrinological presentation and outcomes. METHOD: Patients (< 19 years) registered in the TGM13 registry between 2014 and 2021 for SCST were selected. RESULTS: Sixty-three ovarian SCST (juvenile granulosa tumor (JGT) n = 34, Sertoli-Leydig cell tumor (SLCT) n = 17, other SCST n = 12) were included. Median age was 13.1 years (0.4-17.4). Germline DICER1 pathogenic variant was present in 9/17 SLCT. Sixty-one were FIGO stage I (IC n = 14). Adjuvant chemotherapy was administered for 15. Seven had recurrence (FIGO IA n = 3, IX n = 2, III n = 2), leading to one death. With a median follow-up of 42 months (2.5-92), the 3-year progression-free survival (PFS) was 89% (95% CI 76%-95%). Median age was 6.4 years (0.1-12.9) among the 15 testicular SCST (Leydig cell tumor n = 6, JGT n = 5, Sertoli cell tumor n = 3, mixed SCST n = 1). Tumor-nodes-metastases (TNM) stage was pSI in 14. Eight underwent a tumorectomy, 7 an orchiectomy. None experienced recurrence. Endocrinological data were reviewed for 41 patients (18 prepubescent). Endocrine symptoms were present at diagnosis in 29/34 females and 2/7 males (gynecomastia). After a median follow-up of 11 months, 15 patients had persistent endocrine abnormalities: gynecomastia/breast growth (2 males, 1 prepubescent female), precocious/advanced puberty (4 prepubescent females), and hirsutism/menstruation disorders/voice hoarseness/hot flashes (8 pubescent females). The mean height at the last follow-up was within normal ranges (+0.3 standard deviation). CONCLUSIONS: SCSTs have a favorable prognosis. Tumorectomy appears safe with testicular primary. Endocrinological disorders, common at diagnosis, may persist warranting endocrinological follow-up.

BACKGROUND: Endometrial cancer (EC) is the most common gynecologic malignancy in developed countries, with overall incidence increasing, particularly high-grade disease. There is sparse information regarding quality of life (QOL) in EC survivors with a focus on grade of disease. METHODS: A total of 259 women with EC diagnosed between 2016 and 2020 were identified via the Metropolitan Detroit Cancer Surveillance System and consented to enroll in the Detroit Research on Cancer Survivors cohort study (if African American, n = 138) or completed the baseline interview (if non-Hispanic white, n = 121). Each respondent provided information about their health history, educational attainment, health behaviors, and demographics. The Functional Assessment of Cancer Therapy-General (FACT-G) and Endometrial-specific (FACT-En) were used to assess QOL. RESULTS: Women diagnosed with high-grade (n = 112) and low-grade (n = 147) EC participated in this study. EC survivors with high-grade disease reported significantly lower QOL compared to survivors with low-grade disease (85 vs. 91, respectively, p value = 0.025) as assessed by the FACT-G. This difference was driven by lower physical and functional subscales among women with high-grade disease compared to those with low-grade disease (p value = 0.016 and p = 0.028, respectively). Interestingly, EC-specific QOL measures, as assessed by the FACT-En, did not differ by grade. CONCLUSION: Grade of disease impacts QOL in EC survivors, as well as socioeconomic, psychological, and physical factors. Most of these factors are amenable to interventions and should be assessed in patients after an EC diagnosis.

OBJECTIVES: Muscle dysmorphia (MD) is a disorder affecting mainly men and is characterized by significant dissatisfaction with muscles. The idea that MD could represent an addiction has been theoretically discussed, but no empirical data are available. Based on Foster et al. (2015) framework, the Addiction to Body Image Inventory (ABII) was developed. This study aims to validate the ABII and to evaluate its capacity to capture MD severity. METHODS: A first community sample of 466 participants was recruited and completed the ABII and questionnaires on MD and body esteem. A second sample of 47 men at risk of MD was recruited mostly in gyms and completed the ABII and questionnaires on MD, eating and psychological symptoms. RESULTS: With the community sample, the results showed that the ABII had a valid factorial structure, good internal consistency, and good convergent validity. With the sample of men at risk of MD, the results showed that the ABII had good convergent validity with MD and eating symptoms but not with psychological symptoms. The results of a regression model showed that the ABII explained 12% of the MD variance. CONCLUSIONS: This study brings the first measure of addiction to body image and suggests that MD must be understood as a complex phenomenon including eating symptoms and addictive tendencies.
RESUMO
Gambling's impact on a couple's relationship is an essential element in the gambling disorder (GD). Gamblers tend to lie to their partner to conceal the extent of their gambling problems and debts, which can lead to a serious relational transgression for the couple. One promising avenue is a couple treatment focusing on forgiveness processes. The objective of this study was to determine whether the Integrative Couple Treatment for Pathological Gamblers (ICT-PG) with an emphasis on forgiveness processes helped couples to enhance these processes. A Single-Case Research Design (SCRD) was used with three couples in which one of the members had a GD. The results highlight the importance of jointly analyzing the forgiveness processes between the gamblers and their partner, which constantly influenced each other. These promising results illustrate the relevance of integrating forgiveness processes in treatment for couples where one of the members has a GD.

Although correlated electronic-structure calculations explain very well the normal state of Sr_{2}RuO_{4}, its superconducting symmetry is still unknown. Here we construct the spin and charge fluctuation pairing interactions based on its correlated normal state. Correlations significantly reduce ferromagnetic in favor of antiferromagnetic fluctuations and increase interorbital pairing. From the normal-state Eliashberg equations, we find spin-singlet d-wave pairing close to magnetic instabilities. Away from these instabilities, where charge fluctuations increase, we find two time-reversal symmetry-breaking spin triplets: an odd-frequency s wave, and a doubly degenerate interorbital pairing between d_{xy} and (d_{yz},d_{xz}).
RESUMO
Proper reduction and stable fixation of articular fractures is essential for an early recovery and to avoid late complications. Arthroscopically assisted techniques for minimally invasive fixation have been introduced to reduce local morbidity and improve anatomic reduction of the fragments. However up to date no clear indications for surgery have been given. In addition, the precise rates of functional outcomes and complications are controversial. The hypothesis was the systematic analysis of the available literature would provide precise indications, outcomes and complications of arthroscopically assisted techniques for patellar fracture fixation. A comprehensive literature review was performed using the keywords "patellar fracture", "arthroscopy" with no limit regarding the year of publication. All the selected articles were in English language and were evaluated with the Coleman score by three independent surgeons. The interclass correlation coefficient between the three examiners was calculated. Six full text articles were retrieved. The initial cohort included 60 patients with a displaced transverse fracture in the majority of the cases. At an average FU of 27.2 months the Lysholm score was 91.3. The rate of complication was 7%; Average Coleman score for the three observers was 55.8±6.5 with an ICC of 0.89, indicating adequate inter-rater agreement. Arthroscopically assisted techniques for minimally invasive fixation of patellar fractures represent a reliable option. The positive clinical outcomes and low rates of complications must be confirmed with further studies including larger series and longer FU. LEVEL OF EVIDENCE: Level IV, systematic review of retrospective series.

There is growing interest in the study of white matter (WM) variation across subjects, and in particular the analysis of specific WM bundles, to better understand brain development and aging, as well as to improve early detection of some diseases. Several WM multi-subject clustering methods have been proposed to study WM bundles. These methods aim to overcome the complexity of the problem, which includes the huge size of the WM tractography datasets generated from multiple subjects, the existence of various streamlines with different positions, lengths and geometric forms, as well as the presence of outliers. However, the current methods are not sufficiently flexible to address all of these constraints. Here we introduce a novel dynamic multi-subject clustering framework based on a distributed multiagent implementation of the Multiple Species Flocking model, that we name 3D-Streamlines Stream Flocking (3D-SSF). Specifically, we consider streamlines from different subjects as data streams, and each streamline is assigned to a mobile agent. Agents work together following flocking rules in order to form a flock. Thanks to a similarity function, the agents that are associated with similar streamlines form a flock, whereas the agents that are associated with dissimilar streamlines are considered outliers. We use various experiments performed on noisy synthetic and real human brain data to validate 3D-SSF and demonstrate that it is more efficient and robust to outliers compared to other classical approaches. 3D-SSF is able to extract WM bundles at a population level, while considering WM variation across subjects and eliminating outlier streamlines.

AIM: Peroxisome proliferator-activated receptor (PPAR) γ activation is associated with preferential lipoprotein lipase (LPL)-mediated fatty acid storage in peripheral subcutaneous fat depots. How PPARγ agonism acts upon the multi-level modulation of depot-specific lipid storage remains incompletely understood. METHODS: We evaluated herein triglyceride-derived lipid incorporation into adipose tissue depots, LPL mass and activity, mRNA levels and content of proteins involved in the modulation of LPL activity and fatty acid transport, and the expression/activity of enzymes defining adipose tissue lipogenic potential in rats treated with the PPARγ ligand rosiglitazone (30 mg kg(-1) day(-1) , 23 days) after either a 10-h fasting period or a 17-h fast followed by 6 h of ad libitum refeeding. RESULTS: Rosiglitazone stimulated lipid accretion in subcutaneous fat (SF) ~twofold and significantly reduced that of visceral fat (VF) to nearly half. PPARγ activation selectively increased LPL mass, activity and the expression of its chaperone LMF1 in SF. In VF, rosiglitazone had no effect on LPL activity and downregulated the mRNA levels of the transendothelial transporter GPIHBP1. Overexpression of lipid uptake and fatty acid transport proteins (FAT/CD36, FATP1 and FABP4) and stimulation of lipogenic enzyme activities (GPAT, AGPAT and DGAT) upon rosiglitazone treatment were of higher magnitude in SF. CONCLUSIONS: Together these findings demonstrate that the depot-specific transcriptional control of LPL induced by PPARγ activation extends to its key interacting proteins and post-translational modulators to favour subcutaneous lipid storage.

The role that transduced mouse bone marrow stromal cells (mBMSCs) engineered to overexpress human bone morphogenetic protein 2 (BMP-2) play in healing critical-sized skeletal defects is largely unknown. We evaluated the interaction between host osteoprogenitor cells and donor mBMSCs transduced with either a lentiviral (LV) vector-expressing red fluorescent protein (RFP) with or without BMP-2 that were implanted into a critical-sized femoral defect. Radiographs taken at the time of killing were evaluated using a five-point scaled scoring system. Frozen histologic sections were analyzed to assess both the transduced cells' role in bone repair and the local osteoprogenitor response. There was complete radiographic bridging in 94% of group I (LV-RFPch-BMP-2-cmyc) and 100% of group III (recombinant human BMP-2) specimens. Radiographs demonstrated a lack of healing in group II (LV-RFPch). Mouse BMSCs transduced with an LV-RFPch-BMP-2 vector were able to induce host cells to differentiate down an osteoblastic lineage and heal a critical-sized defect. However, the donor cells appeared to be functioning as a delivery vehicle of BMP-2 rather than actually differentiating into osteoblasts capable of participating in bone repair as evidenced by a lack of colocalization of the transduced cells to the sites of skeletal repair where the host progenitor cells were found.

Parkinson's disease (PD) patients often suffer from gastrointestinal (GI) impairments that are associated with the alteration of dopaminergic (DAergic) neurons in the myenteric nervous system. Growing evidence suggests that inflammation originating from the gut may have a major impact in both the initiation and progression of PD. Here, we investigated the role of the innate immune response in neurodegeneration occurring in central nervous system (CNS) and enteric nervous system (ENS) in response to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), a neurotoxin that produces Parkinsonism in both humans and animal models. We found a strong immune response in the gut of mice treated with MPTP, as demonstrated by the prominent presence of macrophages derived from CD115(+) CD11b(+) Ly6C(Hi) monocytes, known as M1 monocytes, and increased production of IL-1ß and IL-6. Partial depletion of proinflammatory M1 monocytes through intravenous injections of clodronate-encapsulated liposome protects against MPTP-induced reduction of tyrosine hydroxylase (TH) expression in the ENS. In contrast, loss of striatal TH expression in the CNS after MPTP intoxication occurs regardless of partial monocyte depletion. Examination of brain tissue revealed that microglial activation, comprising the majority of the immune response in the CNS after MPTP injections is unaffected by M1 depletion. In vitro experiments revealed that MPTP and MPP(+) act directly on monocytes to elicit a proinflammatory response that is, in part, dependent on the MyD88/NF-κB signaling pathway resulting in nitrite and proinflammatory cytokine production. Taken together, our results demonstrate a critical role for proinflammatory M1 monocytes/macrophages in DAergic alterations occurring in the GI, but not in the brain, in the MPTP model of PD.

The radioisotope palladium (103Pd), encapsulated in millimetre-size seed implants, is widely used in prostate cancer brachytherapy. Gold nanoparticles (Au NPs) distributed in the vicinity of 103Pd radioactive implants, strongly enhance the therapeutic dose of radioactive implants (radiosensitisation effect). A new strategy under development to replace millimetre-size implants, consist in injecting radioactive NPs in the affected tissues. The development of 103Pd@Au NPs distributed in the diseased tissue, could increase the uniformity of treatment (compared with massive seeds), while enhancing the radiotherapeutic dose to the cancer cells (through Au-mediated radiosensitisation effect). To achieve this goal, it is necessary to develop a rapid, efficient, one-pot and easy-to-automatise procedure, allowing the synthesis of core-shell Pd@Au NPs. The novel synthesis route proposed here enables the production of Pd@Au NPs in not more than 4 h, in aqueous media, with minimal manipulations, and relying on biocompatible and non-toxic molecules. This rapid multi-step process consists of the preparation of ultra-small Pd NPs by chemical reduction of an aqueous solution of H2PdCl4 supplemented with ascorbic acid (AA) as reducing agent and 2,3-meso-dimercaptosuccinic acid (DMSA) as a capping agent. Pd conversion yields close to 87% were found, indicating the efficiency of the reaction process. Then Pd NPs were used as seeds for the growth of a gold shell (Pd@Au), followed by grafting with polyethylene glycol (PEG) to ensure colloidal stability. Pd@Au-PEG (TEM: 20.2 ± 12.1 nm) formed very stable colloids in saline solution as well as in cell culture medium. The physico-chemical properties of the particles were characterised by FTIR, XPS, and UV-vis. spectroscopies. The viability of PC3 human prostate cancer cells was not affected after a 24 h incubation cycle with Pd@Au-PEG NPs to concentrations up to 4.22 mM Au. Finally, suspensions of Pd@Au-PEG NPs measured in computed tomography (CT) are found to attenuate X-rays more efficiently than commercial Au NPs CT contrast media. A proof-of-concept was performed to demonstrate the possibility synthesise radioactive 103Pd:Pd@Au-PEG NPs. This study reveals the possibility to synthesise Pd@Au NPs rapidly (including radioactive 103Pd:Pd@Au-PEG NPs), and following a methodology that respects all the strict requirements underlying the production of NPs for radiotherapeutic use (rapidity, reaction yield, colloidal stability, NPs concentration, purification).
RESUMO
BACKGROUND: Lung cancer is the leading cause of worldwide cancer deaths. While smoking is its leading risk factor, few prospective cohort studies have reported on the association of lung cancer with both active and passive smoking. This study aimed to determine the relationship between lung cancer incidence with both active and passive smoking (childhood, adult at home, and at work). PATIENTS AND METHODS: The Women's Health Initiative Observational Study (WHI-OS) was a prospective cohort study conducted at 40 US centers that enrolled postmenopausal women from 1993 to 1999. Among 93 676 multiethnic participants aged 50-79, 76 304 women with complete smoking and covariate data comprised the analytic cohort. Lung cancer incidence was calculated by Cox proportional hazards models, stratified by smoking status. RESULTS: Over 10.5 mean follow-up years, 901 lung cancer cases were identified. Compared with never smokers (NS), lung cancer incidence was much higher in current [hazard ratio (HR) 13.44, 95% confidence interval (CI) 10.80-16.75] and former smokers (FS; HR 4.20, 95% CI 3.48-5.08) in a dose-dependent manner. Current and FS had significantly increased risk for all lung cancer subtypes, particularly small-cell and squamous cell carcinoma. Among NS, any passive smoking exposure did not significantly increase lung cancer risk (HR 0.88, 95% CI 0.52-1.49). However, risk tended to be increased in NS with adult home passive smoking exposure ≥30 years, compared with NS with no adult home exposure (HR 1.61, 95% CI 1.00-2.58). CONCLUSIONS: In this prospective cohort of postmenopausal women, active smoking significantly increased risk of all lung cancer subtypes; current smokers had significantly increased risk compared with FS. Among NS, prolonged passive adult home exposure tended to increase lung cancer risk. These data support continued need for smoking prevention and cessation interventions, passive smoking research, and further study of lung cancer risk factors in addition to smoking.

OBJECTIVE: Endometrial cancer mortality disproportionately affects black women and whether greater prevalence of obesity plays a role in this disparity is unknown. We examine the effect of race on post-surgical complications, length of stay, and mortality specifically in a morbidly obese population. METHODS: Black and white women with endometrial cancer diagnosed from 1996 to 2012 were identified from the University Pathology Group database in Detroit, Michigan, and records were retrospectively reviewed to obtain clinicopathological, demographic, and surgical information. Analysis was limited to those with a body mass index of 40kg/m(2) or greater. Differences in the distribution of variables by race were assessed by chi-squared tests and t-tests. Kaplan-Meier and Cox regression analyses were performed to examine factors associated with mortality. RESULTS: 97 white and 89 black morbidly obese women were included in this analysis. Black women were more likely to have type II tumors (33.7% versus 15.5% of white women, p-value=0.003). Hypertension was more prevalent in black women (76.4% versus 58.8%, p-value=0.009), and they had longer hospital stays after surgery despite similar rates of open vs minimally invasive procedures and lymph node dissection (mean days=5.4) compared to whites (mean days=3.5, p-value=0.036). Wound infection was the most common complication (16.5% in whites and 14.4% in blacks, p-value=0.888). Blacks were more likely to suffer other complications, but overall the proportions did not differ by race. In univariate analyses, black women had higher risk of endometrial cancer-related death (p-value=0.090). No racial differences were noted in adjusted survival analyses. CONCLUSION: A more complete investigation, incorporating socio-demographic factors, is warranted to understand the effects of morbid obesity and race on endometrial cancer.

BACKGROUND: We conducted a retrospective case review of patients with mastoid cavity and active or inactive chronic otitis media (COM) who underwent cochlear implantation and ear obliteration in a single-stage procedure. The objectives of this review are to assess the rates of complications and postoperative infections and to evaluate post-implantation audiologic performance. MATERIALS AND METHODS: All patients with COM and mastoid cavity, associated or not with active disease, who undergo cochlear implantation and obliteration of the ear as a single-stage procedure from November 2004 to April 2013, were included in the review. All the complications were recorded. Open-set sentence scores were used to evaluate the audiologic gain after implantation. RESULTS: Twenty-seven patients were included in our review: Ten with active COM and seventeen with inactive COM. Overall, nine patients (9/27) presented post-operative complications (7/9 were minor): three were amongst active COM patients (30%) as compared to six amongst inactive COM patients (35%), which included the two major complications. A mean gain of 55.9% on open-set sentence scores was obtained after cochlear implantation. DISCUSSION: We found that complications rate of the one-stage cochlear implantation was higher in patients with COM than in global implant population, but most complications were minors and there was no statistical difference between active and inactive COM. In addition, these patients had audiologic scores similar to those found in patients with normal temporal bone anatomy. CONCLUSION: Cochlear implantation performed as a one-stage procedure could be considered as an option of treatment to avoid staging in patients with active and inactive COM. Although these patients need a regular follow-up, they present good post-implantation audiometric scores.

OBJECTIVE: Uterine serous carcinoma (USC) constitutes 10% of uterine cancers but ~40% of deaths. Tumor size is a known prognostic factor in other solid tumors. In endometriod cancers it is one element used to identify the need for complete staging, while its significance in USC is debated. Therefore tumor size was examined as an independent prognostic factor. METHODS: Clinical and pathologic variables were recorded for 236 institutional patients, and those patients in the SEER database with USC. Chi-square and Fisher exact t-tests were utilized and survival data generated via Kaplan-Meier method; multivariate analysis was performed via cox-regression. RESULTS: The patients' mean age was 67.2 years (range 40-91). Survival ranged from 0 to 184 months (mean 42.8). We used a tumor size cut-off of 1cm and noted significant associations with myometrial invasion (p<0.0001), angiolymphatic invasion (p<0.0001), peritoneal washings (p=0.03), stage (p=0.015) and positive lymph nodes (p=0.05). Furthermore, recurrence was associated with larger tumors (p=0.03). In multivariate analysis, extra-uterine disease was the only factor associated with both recurrence and survival. Review of the SEER database noted association of larger tumors with lymph node involvement and a significant survival advantage with tumors <1cm in both univariate and multivariate analysis. CONCLUSIONS: Treatment options for USC are often predicated on the surgical stage and therefore components of the staging are vitally important. The 1cm tumor-size cut-off should be studied prospectively as a prognostic indicator of survival and recurrence in USC and considered for inclusion in USC staging.

Vulvovaginitis is the most frequent gynecologic pathology among prepubertal females. An infectious cause is found in 30% of cases and is highly associated with the presence of vaginal discharge upon examination. Neisseria gonorrhoeae may be one of the causative agents. Since N. gonorrhoeae is a common sexually transmitted disease, sexual abuse should be considered in the pediatric setting. We report the case of a 5-year-old girl with N. gonorrhoeae vulvovaginitis. Her previous history, multiple interviews with the patient and her parents, and clinical examination showed no evidence or signs of sexual abuse. Both parents presented gonorrhea, urethritis for the father and vaginitis for the mother. The discrepancy between pediatric evaluation and the presence of a bacterium associated with sexually transmitted disease led us to consider other means of contamination. Previous studies have shown that other routes of transmission are possible but are often neglected. Hence, contamination can be transmitted by the hands or mostly through passive means (towels, rectal thermometer, etc.). Many epidemics have been noted in group settings with young girls with no evidence of sexual transmission. Therefore, we concluded that this patient's infection was likely an accidental transmission within her family. The acknowledgement of these transmission routes is very important in order to avoid misguided suspicion of sexual abuse and the possible traumatic family and psychosocial consequences.

A growing body of evidence supports a role of inflammation in the loss of central nervous system neurons both to acute and chronic insults, while its contribution to the loss of neurons in the enteric nervous system remains largely uninvestigated. We have addressed this issue by exploring the role of inflammation in dopaminergic (DAergic) myenteric neuronal degeneration secondary to MPTP lesioning in mice deficient in MyD88, a protein implicated in the cascade of events leading to the innate immune response. Our results show that MPTP-treated MyD88 knock out (MyD88(-/-)) mice were protected against the toxin-induced TH-immunoreactive neuronal degeneration at the level of the myenteric plexus of the distal ileum, which causes a 50% loss of such neurons in MPTP-treated WT mice. Interestingly, the density of macrophages was the same in the MyD88(-/-) mice subjected to MPTP, as opposed to the increase in density observed in wild-type (WT) mice treated with the toxin, which was due to an infiltration of monocyte from the blood to the myenteric tissue. Furthermore, in MPTP-treated MyD88(-/-) mice, resident macrophages exhibited a predominant pro-repair phenotype, which could have contributed to the protection of DAergic neurons in the myenteric plexus. Taken together, our results suggest a critical role for the MyD88-dependent pathway in the gastrointestinal DAergic degeneration induced by MPTP.
