"My Husband Affects Me More Than My Cancer": Reflections on Simultaneous Intimate Partner Violence and Breast Cancer Experience in a 48-Year-Old Woman.

In this paper, we present the case of a 48-year-old woman diagnosed with early breast cancer. As candidate for mastectomy, she refused immediate reconstruction. She was referred to a psycho-oncologist for further evaluation and support. Psychological sessions helped reveal a history of intimate partner violence and helped clarify the reason for her refusal to undergo immediate reconstruction. Experience with this case highlights the importance of a multidisciplinary practice in which collaboration between surgeons, oncologists, and mental health professionals leads to a more in-depth understanding of the apparently paradoxical behaviors of patients, and to better care for their needs.

Single-Dose Intracardiac Injection of Pro-Regenerative MicroRNAs Improves Cardiac Function After Myocardial Infarction.

RATIONALE: Recent evidence indicates that a few human microRNAs (miRNAs), in particular hsa-miR-199a-3p and hsa-miR-590-3p, stimulate proliferation of cardiomyocytes and, once expressed in the mouse heart using viral vectors, induce cardiac regeneration after myocardial infarction. Viral vectors, however, are not devoid of safety issues and, more notably, drive expression of the encoded miRNAs for indefinite periods of time, which might not be desirable in light of human therapeutic application. OBJECTIVE: As an alternative to the use of viral vectors, we wanted to assess the efficacy of synthetic miRNA mimics in inducing myocardial repair after single intracardiac injection using synthetic lipid formulations. METHODS AND RESULTS: We comparatively analyzed the efficacy of different lipid formulations in delivering hsa-miR-199a-3p and hsa-miR-590-3p both in primary neonatal mouse cardiomyocytes and in vivo. We established a transfection protocol allowing persistence of these 2 mimics for at least 12 days after a single intracardiac injection, with minimal dispersion to other organs and long-term preservation of miRNA functional activity, as assessed by monitoring the expression of 2 mRNA targets. Administration of this synthetic formulation immediately after myocardial infarction in mice resulted in marked reduction of infarct size and persistent recovery of cardiac function. CONCLUSIONS: A single administration of synthetic miRNA-lipid formulations is sufficient to stimulate cardiac repair and restoration of cardiac function.

Changes in quality of life and functional capacity after lung transplantation: A single-center experience.

Lung transplantation (LT) increases the life expectancy of patients affected by end stage pulmonary disease; specifically, its ultimate aims are to improve survival and health related quality of life (HRQoL). The aim of the present longitudinal study was to determine the HRQoL trajectory and changes in functional capacity from time of entry in the waiting list for LT to 2 year after LT. The study included sixty-nine outpatients enrolled in a single medical center when they entered the waiting list for LT and who subsequently received it. They were then followed up over 2 years after LT. HRQoL was assessed by the physical and mental component summary (PCS and MCS) scores of the 36-item Short Form Health Survey (SF-36) and Saint George's Respiratory Questionnaire (SGRQ). Psychological distress was evaluated with the General Health Questionnaire (GHQ), and functional capacity was investigated using the six-minute walk test (6MWT) and forced expiratory volume (FEV1). Patients showed low SF-36 PCS (30.5±7.8) and SGRQ total (61.8±17.5) scores at entry in the waiting list, but exhibited significant changes over time after LT (p<0.001). Furthermore, patients who showed an increase of at least 50% in SF36 PCS and SGRQ scores at 6 months survived longer. Both FEV1 and 6MWT distance as well as GHQ scores significantly changed over time, with improvements occurring in the first 6 months after LT but no major changes thereafter. Out of the 69 patients enrolled, 32 died over a median follow-up of 51 months. Although mortality tended to be slightly higher for patients with lower HRQoL at the baseline assessment, this difference was not statistically significant. HRQoL evaluations appear critical in the follow-up of LT candidates, in particularly SGRQ, because of its specificity in targeting respiratory symptoms and functional wellbeing.

Epigenetic modification at Notch responsive promoters blunts efficacy of inducing notch pathway reactivation after myocardial infarction.

RATIONALE: The Notch pathway plays a key role in stimulating mammalian cardiomyocyte proliferation during development and in the early postnatal life; in adult zebrafish, reactivation of this pathway is also essential to drive cardiac regeneration after injury. OBJECTIVE: We wanted to assess efficacy of Notch pathway stimulation in neonatal and adult hearts as a means to induce cardiac regeneration after myocardial infarction in mice. METHODS AND RESULTS: In early postnatal life, cardiomyocyte exit from the cell cycle was paralleled by decreased Notch signaling and the establishment of a repressive chromatin environment at Notch-responsive genes, characterized by recruitment of the polycomb group enhancer of zeste homolog 2 methyltransferase and the acquisition of the histone 3 Lysine 27 trimethylation histone mark, as detected by chromatin immunoprecipitation. Forced Notch pathway activation by adenoassociated virus gene transfer of activated Notch1 or its ligand Jagged1 expanded the proliferative capacity of neonatal cardiomyocytes; this correlated with increased transcription of Notch target genes and maintenance of an open chromatin conformation at their promoters. The same adenoassociated virus vectors, however, were largely ineffective in stimulating cardiac repair after myocardial infarction in adult mice, despite optimal and long-lasting transgene expression. Analysis of Notch-responsive promoters in adult cardiomyocytes showed marks of repressed chromatin and irreversible CpG DNA methylation. Induction of adult cardiomyocyte re-entry into the cell cycle with microRNAs was independent from Notch pathway reactivation. CONCLUSIONS: Notch pathway activation is crucial in regulating cardiomyocyte proliferation during the early postnatal life, but it is largely ineffective in driving cardiac regeneration in adults, because of permanent epigenetic modification at Notch-responsive promoters.

Biomimetic Polymers for Cardiac Tissue Engineering.

Heart failure is a morbid disorder characterized by progressive cardiomyocyte (CM) dysfunction and death. Interest in cell-based therapies is growing, but sustainability of injected CMs remains a challenge. To mitigate this, we developed an injectable biomimetic Reverse Thermal Gel (RTG) specifically engineered to support long-term CM survival. This RTG biopolymer provided a solution-based delivery vehicle of CMs, which transitioned to a gel-based matrix shortly after reaching body temperature. In this study we tested the suitability of this biopolymer to sustain CM viability. The RTG was biomolecule-functionalized with poly-l-lysine or laminin. Neonatal rat ventricular myocytes (NRVM) and adult rat ventricular myocytes (ARVM) were cultured in plain-RTG and biomolecule-functionalized-RTG both under 3-dimensional (3D) conditions. Traditional 2D biomolecule-coated dishes were used as controls. We found that the RTG-lysine stimulated NRVM to spread and form heart-like functional syncytia. Regarding cell contraction, in both RTG and RTG-lysine, beating cells were recorded after 21 days. Additionally, more than 50% (p value < 0.05; n = 5) viable ARVMs, characterized by a well-defined cardiac phenotype represented by sarcomeric cross-striations, were found in the RTG-laminin after 8 days. These results exhibit the tremendous potential of a minimally invasive CM transplantation through our designed RTG-cell therapy platform.

Cognitive-behavioral treatment reduces attrition in treatment-resistant obese women: results from a 6-month nested case-control study.

OBJECTIVE: The aim of this nested case-control study was to compare the effectiveness of cognitive-behavioral treatment (CBT) for treatment-resistant obese (body mass index [BMI] ≥ 30 kg/m²) women compared with standard dietary treatment. The main outcome measures were attrition and weight loss success. METHODS: We designed a 6-month case-control study, nested within a cohort of adult (age ≥ 18 years) treatment-resistant (history of at least two previous diet attempts) obese women. Cases were 20 women who were offered CBT sessions. Controls (n=39) were randomly selected from the source population and matched to cases in terms of baseline age, BMI, and number of previous diet attempts. RESULTS: Compared with controls, cases were significantly more likely to complete the 6-month program in both age-adjusted (odds ratio [OR]=2.94, 95% confidence interval [CI]=1.05-8.97) and multivariate-adjusted (OR=2.77, 95% CI=1.02-8.34) analyses. In contrast, cases were not more likely to achieve weight loss success in age-adjusted (OR=1.32, 95% CI=0.86-1.67) and multivariate-adjusted (OR=1.21, 95% CI=0.91-1.44) analyses. CONCLUSIONS: Compared with a standard dietary treatment, CBT was significantly more effective in reducing attrition in treatment-resistant obese women, without differences in terms of weight loss success.

Effect of class IV laser therapy on chemotherapy-induced oral mucositis: a clinical and experimental study.

Oral mucositis (OM) is a serious and acute side effect in patients with cancer who receive chemotherapy or radiotherapy, often leading to the suspension of therapy and a need for opioid analgesic and enteral/parenteral nutrition, with an effect on patient survival. Among the various interventions proposed in OM management, laser therapy is becoming a recommended treatment option but has limitations due to its heterogeneous laser parameters. Here, we report on our successful clinical experience on the use of class IV laser therapy to treat OM induced by different chemotherapy regimens. To shed light on the mechanisms of action of laser therapy in improving OM resolution, we have developed an animal model of chemotherapy-induced OM, in which we compare the efficacy of the standard low-power laser therapy protocol with an innovative protocol, defined as high-power laser therapy. We show that high-power laser therapy is more effective than low-power laser therapy in improving OM lesion healing, reducing the inflammatory burden, and preserving tissue integrity. In addition, high-power laser therapy has been particularly effective in promoting the formation of new arterioles within the granulation tissue. Our results provide important insights into the mechanism of action of biostimulating laser therapy on OM in vivo and pave a way for clinical experimentation with the use of high-power laser therapy.

Ethical Issues in Living Donor Kidney Transplantation: An Update from a Psychosocial Perspective.

Living donor kidney transplantation (LDKT) currently represents the treatment of choice for patients with end-stage renal failure. LDKT is a serious event with profound psychological, interpersonal, familial, and social implications. Over the last few years, there has been an exponential growth in living donation programs involving genetically and emotionally related donors, as well as people who donate to an unrelated and unknown subject. The implementation of paired exchange programs, Samaritan donation, and preemptive transplantation raise further ethical issues, which are inextricably linked to the unique psychosocial context of both the donor and the recipient. The present narrative review aims to provide an update on the main ethical challenges related to LDKT. We conducted a comprehensive literature search in PubMed/Medline. The results of the most relevant studies were narratively synthesized from a psychosocial perspective around the four principles of biomedical ethics: autonomy, beneficence, non-maleficence, and justice. Finally, we discussed the potential future directions to provide an effective, patient-centered, and ethical psychosocial assessment and follow-up of living donors and recipients that underwent LDKT.

Carbon nanotubes promote growth and spontaneous electrical activity in cultured cardiac myocytes.

Nanoscale manipulations of the extracellular microenvironment are increasingly attracting attention in tissue engineering. Here, combining microscopy, biological, and single-cell electrophysiological methodologies, we demonstrate that neonatal rat ventricular myocytes cultured on substrates of multiwall carbon nanotubes interact with carbon nanotubes by forming tight contacts and show increased viability and proliferation. Furthermore, we observed changes in the electrophysiological properties of cardiomyocytes, suggesting that carbon nanotubes are able to promote cardiomyocyte maturation.

Ethics of Bariatric Surgery in Adolescence and Its Implications for Clinical Practice.

Obesity is increasingly prevalent among adolescents. Clinical and research data support the use of bariatric surgery (BS) as a treatment option for severely obese adolescents, with good results in terms of weight loss, improvement or resolution of comorbidities, and compliance to follow up. Nevertheless, concerns still remain, with significant disparities among countries and ethical concerns mainly raised by performing an irreversible and invasive procedure in adolescence, with potential life-long alterations. In this context, the purpose of this narrative review was to discuss the main current ethical challenges in performing BS in adolescence and to inform appropriate clinical management in the field. The core ethical principles of autonomy, beneficence, nonmaleficence, and justice were revised in terms of patient-centered healthcare through the lens of psychosocial implications. The review concludes with a discussion regarding the potential directives for future research for effective, patient-centered, and ethical management of obesity in the adolescent population.

Clinical and psychological features of normal-weight women with subthreshold anorexia nervosa: a pilot case-control observational study.

OBJECTIVE: Weight preoccupations have been frequently reported in normal-weight subjects. Subthreshold anorexia nervosa (s-AN, all DSM IV TR criteria except amenorrhea or underweight) is a form of eating disorder not otherwise specified that has received scarce scientific attention. Under a case-control design we compared the general characteristics, body composition, and psychopathological features of normal-weight patients with s-AN with those of BMI- and sex-matched controls. DESIGN: Participants in this pilot study included 9 normal-weight women who met the DSM IV TR criteria for s-AN and 18 BMI-matched normal-weight controls. The general characteristics of the study participants were collected by questionnaire. Body composition was measured by bioelectrical impedance. Behavioral and psychological measures included the standardized symptom checklist (SCL-90-R) and the eating disorder inventory (EDI-2). RESULTS: There were no differences in age, education, employment status, marital status, and history of previous slimming treatment in the two study groups. In addition, anthropometric measures and body composition of s-AN patients and BMI-matched normal weight controls were not significantly different. In the s-AN subgroup, we found a significant relationship between waist circumference and the SCL-90-R obsessivity-compulsivity scale (n=9, r=-0.69, p<0.05). After multiple regression analysis, the SCL-90-R obsessivity-compulsivity scale (beta = 0.61, t=2.7, p=0.017) was the only independent predictor of the presence s-AN in our study cohort. CONCLUSIONS: These pilot results suggest that psychopathological criteria (particularly related to the obsessivity-compulsivity dimension) may be more useful than anthropometric measures for screening of s-AN in normal-weight women.

Bariatric Surgery: Psychosocial Aspects and Quality of Life.

Obesity is a major worldwide health problem, causing an ongoing and decades-long pandemic, which the WHO has termed the "global obesity epidemic", concurrent with the COVID-19 pandemic [...].

A new laser device for ultra-rapid and sustainable aerosol sterilization.

The current COVID-19 pandemic has highlighted the importance of aerosol-based transmission of human pathogens; this therefore calls for novel medical devices which are able to sterilize contaminated aerosols. Here we describe a new laser device able to sterilize droplets containing either viruses or bacteria. Using engineered viral particles, we determined the 10,600 nm wavelength as the most efficient and exploitable laser source to be manufactured in a commercial device. Given the lack of existing working models to reproduce a human aerosol containing living microbial particles, we developed a new system mimicking human droplet formation and preserving bacterial and viral viability. This evidenced the efficacy of 10,600 nm laser light to kill two aerosol transmitted human pathogens, Legionella pneumophila and SARS-CoV-2. The minimal exposure time of <15 ms was required for the inactivation of over 99% pathogens in the aerosol; this is a key element in the design of a device that is safe and can be used in preventing inter-individual transmission. This represents a major advantage over existing devices, which mainly aim at either purifying incoming air by filters or sterilizing solid surfaces, which are not the major transmission routes for airborne communicable diseases.

Cardioprotective factors against myocardial infarction selected in vivo from an AAV secretome library.

Therapies for patients with myocardial infarction and heart failure are urgently needed, in light of the breadth of these conditions and lack of curative treatments. To systematically identify previously unidentified cardioactive biologicals in an unbiased manner in vivo, we developed cardiac FunSel, a method for the systematic, functional selection of effective factors using a library of 1198 barcoded adeno-associated virus (AAV) vectors encoding for the mouse secretome. By pooled vector injection into the heart, this library was screened to functionally select for factors that confer cardioprotection against myocardial infarction. After two rounds of iterative selection in mice, cardiac FunSel identified three proteins [chordin-like 1 (Chrdl1), family with sequence similarity 3 member C (Fam3c), and Fam3b] that preserve cardiomyocyte viability, sustain cardiac function, and prevent pathological remodeling. In particular, Chrdl1 exerted its protective activity by binding and inhibiting extracellular bone morphogenetic protein 4 (BMP4), which resulted in protection against cardiomyocyte death and induction of autophagy in cardiomyocytes after myocardial infarction. Chrdl1 also inhibited fibrosis and maladaptive cardiac remodeling by binding transforming growth factor-ß (TGF-ß) and preventing cardiac fibroblast differentiation into myofibroblasts. Production of secreted and circulating Chrdl1, Fam3c, and Fam3b from the liver also protected the heart from myocardial infarction, thus supporting the use of the three proteins as recombinant factors. Together, these findings disclose a powerful method for the in vivo, unbiased selection of tissue-protective factors and describe potential cardiac therapeutics.

Bone morphogenetic protein 1.3 inhibition decreases scar formation and supports cardiomyocyte survival after myocardial infarction.

Despite the high prevalence of ischemic heart diseases worldwide, no antibody-based treatment currently exists. Starting from the evidence that a specific isoform of the Bone Morphogenetic Protein 1 (BMP1.3) is particularly elevated in both patients and animal models of myocardial infarction, here we assess whether its inhibition by a specific monoclonal antibody reduces cardiac fibrosis. We find that this treatment reduces collagen deposition and cross-linking, paralleled by enhanced cardiomyocyte survival, both in vivo and in primary cultures of cardiac cells. Mechanistically, we show that the anti-BMP1.3 monoclonal antibody inhibits Transforming Growth Factor ß pathway, thus reducing myofibroblast activation and inducing cardioprotection through BMP5. Collectively, these data support the therapeutic use of anti-BMP1.3 antibodies to prevent cardiomyocyte apoptosis, reduce collagen deposition and preserve cardiac function after ischemia.

High frequency of psychopathology in subjects wishing to lose weight: an observational study in Italian subjects.

OBJECTIVE: To investigate the frequency of psychiatric disorders in subjects wishing to lose weight categorized according to BMI. DESIGN: Cross-sectional study. SETTING: An academic outpatient clinical nutrition service in Italy. SUBJECTS: A total of 207 subjects (thirty-nine men and 168 women; mean age: 38·7 (sd 14·1) years) consecutively attending the study centre for the first time between January 2003 and December 2006. RESULTS: In the entire study group, eighty-three (40 %) subjects had a psychiatric disorder according to criteria of the Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision. Eating disorders were the most prevalent psychiatric condition (thirty-six subjects, 17·4 %), followed by mood and anxiety disorders (9·7 % and 8·7 %, respectively). The frequency of psychiatric disorders among different BMI categories was as follows: 75·0 % in underweight, 50·0 % in normal weight, 33·3 % in overweight and 33·3 % in obese subjects. CONCLUSIONS: Psychiatric disorders may be frequently found in subjects wishing to lose weight. Our results highlight the importance of psychiatric assessment especially in underweight and normal-weight subjects.

Online Videogames Use and Anxiety in Children during the COVID-19 Pandemic.

Videogames use has constantly increased among children and adolescents, with uncertain consequences on their health. This study aimed to assess the prevalence of videogames use and addiction in a sample of Italian children during the COVID-19 pandemic and their association with anxiety symptoms. One hundred and sixty-two children (M/F:78/84; age range: 8-10 years; average age 9.4 ± 0.7 years) completed the Videogame Addiction Scale for Children (VASC), the Test of Anxiety and Depression (TAD) and the Children's Anxiety Meter-State (CAM-S). Demographic variables and data on the access to electronic tools and games preferences were also collected. Overall, 96.3% of the study participants stated to have access to one or more device. They reported a low risk of videogame addiction (VASC score (mean ± SD): 46.7 ± 15.4), a moderate level of trait anxiety (TAD score (mean ± SD): 135 ± 16.8) and a low state anxiety (CAM-S score (mean ± SD): 2.2 ± 2.1). Males reported to spend more time on videogames, to perceive higher self-control and to be more influenced by reinforcement mechanisms; females described higher levels of trait anxiety. In the regression analysis, state anxiety was a predictor of videogame use and addiction (p = 0.01). Further research is needed to confirm these data and to maximize the developmentally positive effects of videogames and preventing the negative consequences.

The role of mood states in cyberbullying and cybervictimization behaviors in adolescents.

Cyberbullying is an intentional aggressive behavior repeatedly perpetrated by a single person or a group against a peer who can not easily defend, characterized by the use of electronic forms of contact. This phenomenon is a public health concern with serious implications for adolescents' mental health. We aimed to investigate the role of gender, age, and subjective self perceived mood states in cyberbullying and victimization (being a victim of cyberbullying) behaviors. A total of 554 adolescents (293 males and 261 females, age 15.27; SD = 2.21) completed the Florence Cyber-Bullying Cyber-Victimization Scales (FCBVSs) and the Profile of Mood States (POMS). Older age and male gender were associated to both cyberbullying and victimization.The aggressiveness/anger (A) and confusion/bewilderment (C) factors measured by the POMS were predictors of all types of cyberbulliyng and cybervictimization behaviors; the tension/anxiety (T) factor was a predictor of all cyberbullying behaviors and of the FCBVSs impersonification subscale of cybervictimization. Subjective specific mood states may contribute to both cyberbulliyng and victimization behaviors, suggesting the potential benefit of preventive strategies addressing the recognition and management of mood states in adolescents.

Psychiatric and psychological evaluation in living donor kidney transplantation: a single center experience.

Background: Living donor kidney transplantation (LDKT) is the treatment of choice for end stage renal disease. LDKT involves complex psychosocial issues, which remain partially unexplored. Methods: The study involved all potential living donors and recipient pairs consecutively referred for psychosocial evaluation from the nephrologist. Clinical and sociodemographic variables including prior psychiatric history, previous and current use of psychopharmacological therapy, motivation and information about the transplant procedure were collected. Study participants completed the Symptom Checklist-90-R (SCL-90-R) to assess psychopathological distress. Results: Fifty-three donor/recipient pairs underwent psychiatric and psychological evaluation. Seven subjects (13%) in the recipient group and 13 subjects (25%) in the donor group reported a history of psychological distress and/or psychiatric conditions. A psychiatric diagnosis was confirmed in 4 recipients (7.5% of the study sample, including autism spectrum disorder, histrionic personality disorder, and anxiety-depressive disorders) and 5 donors (9%, including narcissistic personality disorder in one case and anxiety-depressive disorders). SCL-90-R GSI mean scores were 0.3 ±0.3 and 0.2 ±0.2 for the recipient and donor groups, respectively. Overall, 8 couples (15%) suspended the living donation pathway before transplantation. Four couples were excluded for a new onset medical condition. The psychological and psychiatric evaluation excluded one candidate. One couple dropped out before completing the scheduled exams. One recipient refused to undergo crossover renal transplantation, while 1 donor candidate withdrew her consent for transplantation at the end of the evaluation process. Conclusions: Limited but significant psychopathological distress in donors and recipients supports the usefulness of psychiatric and psychological competencies within the transplant team.

Elevated urine levels of bufotenine in patients with autistic spectrum disorders and schizophrenia.

OBJECTIVE: Previous studies have suggested that the endogeneous psychotomimetic molecule bufotenine (N-N-dimethyl-5-idroxytryptamine) may play a role in the pathogenesis of severe mental disorders. The potential association of bufotenine with the clinical features of autism and schizophrenia is not entirely understood. In this study, we measured urinary levels of bufotenine in subjects with autistic spectrum disorder (ASD), schizophrenia and healthy comparison subjects free of psychiatric symptoms. We also sought to assess whether urine concentrations of this molecule may be associated with the clinical characteristics of psychiatric patients. DESIGN: Urine bufotenine levels were measured using a high-performance liquid chromatography-mass spectrometry (HPLC-MS) assay in young adults with severe ASD (n=15), patients with schizophrenia (n=15), and healthy control subjects (n=18). The Vineland Adaptive Behavior Scale was used to measure adaptive behaviors in ASD individuals. The Brief Psychiatric Rating Scale (BPRS) was used for patients with schizophrenia. RESULTS: Urine bufotenine levels were significantly higher in ASD subjects (3.30 +/- 0.49 microg/L, p<0.05) and patients with schizophrenia (4.39 +/- 0.43 microg/L, p<0.001) compared with controls (1.53 +/- 0.30 microg/L). Among patients with ASD, there was a significant positive correlation between urine bufotenine and hyperactivity scores on the Vineland Adaptive Behavior Scale (r=0.479, p<0.05). No other associations were detected. CONCLUSIONS: Our results indicate that elevated urine levels of the endogeneous psychotomimetic molecule bufotenine may play a role in ASD and schizophrenia, and can be correlated with hyperactivity scores in autism.
