RESUMO

Autism is a neurodevelopmental disorder that is more frequently diagnosed in men. Nevertheless, through current diagnostic tools, women have also been found to be affected by this disorder, but in different ways. Few studies have been conducted regarding unique periods of life, such as motherhood. Yet, extant literature has already described the existence of a comorbidity between autism and postpartum depression. Thus, this study aimed to compare the maternal care sphere between two animal models of these diseases. Lactating rats were subdivided into three groups (n = 8 animals/group): 1) control dams; 2) maternal separation (MS) dams, separated from their litter for 3 h daily from lactating day (LD) 2-12 for postpartum depression induction; and 3) valproic acid (VPA) dams, which were the pups of dams treated with 400 mg/kg of VPA (i.p.) on gestational day 12.5 for autism induction. Maternal care tests were performed during lactation and, after weaning, dams were euthanized for the analysis of dopaminergic system on the prefrontal cortex. The results showed an impairment of maternal care of MS dams and an improvement of VPA dams, as well as alterations on dopaminergic system that corroborates the behavior data. These findings indicate that VPA dams express better maternal care, even with cognitive and socialization difficulties. This is probably due to a hyper-focus, as opposed to MS dams, which mimic the maternal care dysfunction expressed by women with postpartum depression.

RESUMO

Seizure frequency in treatment-resistant epilepsies seems to be decreased by cannabidiol (CBD), but contrasting data are available on its effect on sleep, behavior, and quality of life (QoL), and no data is reported on its effect on parental stress in patients with epilepsy (PWE). Thus, we conducted a retrospective study on a cohort of children and adults with drug-resistant epilepsy (DRE) who had been treated with highly purified, pharmaceutical-grade CBD to evaluate its effects on seizure frequency, QoL, behavior, parental stress, and sleep. Eighteen patients (12 adults and 6 children) were included in the cohort and followed for a median of 9 months. At the last follow-up (Tn), nine patients (50%) were considered CBD responders with at least a 50% decrease in seizure frequency. No serious adverse effects were found. No statistically significant differences were found concerning sleep, including daytime sleepiness, and no statistically significant effect was found on parental stress at Tn. An improvement was found for social interaction in quality of life (p < 0.05) for all patients. Our results demonstrate that CBD is a safe and effective antiseizure medication (ASM). CBD doesn't seem to affect sleep measures in adults and children or worsen daytime sleepiness. However, CBD improves specific QoL measures, which could indicate a possible use of CBD for other childhood disabilities. No impact of CBD was seen on parental stress, which could possibly be due to the limited follow-up or could mean that parental stress is not dependent on seizure frequency.

RESUMO

Background: In the workplace, it is increasingly important to promote interventions to improve the work environment that can combine compliance with regulations related to worker health and safety protection with health promotion interventions. The objective of our study is to investigate the status of the implementation of various health management measures through questionnaires submitted to Occupational Physicians (OPs) and Prevention and Protection Service Managers (PPSMs). Methods: This study was conducted between September 2022 and November 2022. Healthcare professionals were invited to voluntarily answer the questions, administered through a Google form, of a standardized questionnaire (Cronbach's alpha=0.887) based on the study made by Hoge et al. (2019): the first part collected demographic information and the other four were relating to the state of implementation of interventions attributable to the Total Worker Health® approach. Results: 89 OPs and PPSMs were involved. The univariate and multivariate analysis shows that, overall, women and PPSMs have a higher degree of dissatisfaction related to various health management measures within companies; most workers are fairly satisfied with health and safety protection in the workplace; finally, according to healthcare professionals, aspects of primary prevention and work management/organization would need to be improved. Conclusions: This study shows that in Italian companies there is often no full application of Total Worker Health® principles. The affirmation of this approach, awareness should be raised, first and foremost, among employers, but also among prevention figures and consultants about all the benefits of Total Worker Health®: one among all, an 'economic' advantage.

RESUMO

Upper body muscle involvement has never been systematically investigated in GNE myopathy (GNEM). Aims of our study were to explore upper body involvement in GNEM patients by means of muscle MRI, to compare the degree of pathology with that of lower body and to validate the MRI pattern of the lower limbs in novel patients. MRI scans of 9 GNEM patients were retrospectively evaluated. T1-weighted and short-tau inversion recovery images were scored. As a result, serratus anterior was involved in all patients, followed by subscapularis and trapezius muscles. The majority of scans consistently showed hypotrophy of pectoralis minor. Conversely, cranial muscles including the tongue were always spared while pectoralis major and latissimus dorsi were relatively spared. We confirmed the known pattern of involvement in the pelvic girdle and limbs, that were more significantly affected than the upper girdle in all disease stages. Paraspinal muscles were also frequently affected displaying both a cranio-caudal and latero-medial gradient of severity along the body axis. Upper girdle MRI highlights a selective muscle involvement in GNEM, offering an added value in patients' diagnostic workup and deep stratification.

RESUMO

ABSTRACT: COVID-19 has dramatically affected working forces. We aim to report our occupational medicine service's experience in managing suspected COVID-19 cases during the pandemic through a retrospec-tive observational study. We compared the number of days employees were absent from work due to flu-like symptoms from March 2020 to February 2021 to the same period the previous year (2019-2020). Two hundred thirty-four patients (+47.2% compared to the previous year) who tested negative for SARS-CoV-2 reported flu-like symp-toms; the number of days of absence from work was 2812 (+190.2% compared to the previous year). On average, employees with flu-like symptoms lost 12.07 working days compared to 6.12 in the previous year (p<0.0001). In conclusion, in our sample COVID-19 has increased the number of working day loss. However, our approach proved to be important, especially during the first months of the pandemic, to limit SARS-CoV-2 spread in workplaces.

RESUMO

BACKGROUND AND PURPOSE: The aim was to define the radiological picture of facioscapulohumeral muscular dystrophy 2 (FSHD2) in comparison with FSHD1 and to explore correlations between imaging and clinical/molecular data. METHODS: Upper girdle and/or lower limb muscle magnetic resonance imaging scans of 34 molecularly confirmed FSHD2 patients from nine European neuromuscular centres were analysed. T1-weighted and short-tau inversion recovery (STIR) sequences were used to evaluate the global pattern and to assess the extent of fatty replacement and muscle oedema. RESULTS: The most frequently affected muscles were obliquus and transversus abdominis, semimembranosus, soleus and gluteus minimus in the lower limbs; trapezius, serratus anterior, latissimus dorsi and pectoralis major in the upper girdle. Iliopsoas, popliteus, obturator internus and tibialis posterior in the lower limbs and subscapularis, spinati, sternocleidomastoid and levator scapulae in the upper girdle were the most spared. Asymmetry and STIR hyperintensities were consistent features. The pattern of muscle involvement was similar to that of FSHD1, and the combined involvement of trapezius, abdominal and hamstring muscles, together with complete sparing of iliopsoas and subscapularis, was detected in 91% of patients. Peculiar differences were identified in a rostro-caudal gradient, a predominant involvement of lower limb muscles compared to the upper girdle, and in the higher percentage of STIR hyperintensities in FSHD2. CONCLUSION: This multicentre study defines the pattern of muscle involvement in FSHD2, providing useful information for diagnostics and clinical trial design. Both similarities and differences between FSHD1 and FSHD2 were detected, which is also relevant to better understand the pathogenic mechanisms underlying the FSHD-related disease spectrum.

RESUMO

The equine interspinous ligament (ISL) consists of an oblique crossing arrangement of collagenous bundles which are thought to counteract the tensile and rotational forces of distraction between the spinous processes (SPs) in the caudal thoracic and cranial lumbar spine. The aim of this controlled histological study was to assess the structural anatomy and innervation of the ISL in horses with clinically significant overriding (dorsal) SPs (ORSPs) and to compare the findings with the ISL of normal horses. Samples of the ISL were obtained from 10 horses that underwent subtotal ostectomy for treatment of ORSPs. Control samples were obtained from horses without spinal pathology. Histological staining of ISL sections with haematoxylin and eosin was performed to assess the morphology of the ligaments and with Alcian blue-periodic acid-Schiff to determine the proteoglycan and glycosaminoglycan content. Immunohistochemistry for S100 was performed for quantitative evaluation of nerves within the ISL. The ISL in horses with ORSPs had an altered collagen fibre alignment and arrangement of the ligamentous layers when compared to healthy controls. A significant increase in fibrocartilaginous tissue with evidence of fibrocartilaginous metaplasia was detected (P=0.001). The number of nerves in the ISL samples was significantly higher in horses with ORSPs than in controls (P=0.017). Structural alterations of the ISL, including loss of fibre alignment and fibrocartilaginous metaplasia, are associated with ORSPs in the equine thoracolumbar spine. In addition, an increase in innervation of the ISL in horses with ORSPs, compared to normal, may explain the thoracolumbar pain experienced by some horses with ORSPs.

RESUMO

BACKGROUND: Several diet patterns have been suggested as involved in processes of spermatogenesis and thus in male subfertility. To study the relation between Mediterranean diet and abnormal sperm parameters in men of subfertile couples, we performed a cross-sectional analysis of baseline data from a prospective cohort study. METHODS: Patients were enrolled in an Italian Fertility Clinic. Couples undergoing assisted reproduction techniques (ART) were interviewed to obtain information on personal and health history, lifestyle habits, and diet, on the day of oocyte retrieval. On the same day, a semen sample was also collected and analyzed to proceed with ART. Adherence to Mediterranean diet was evaluated using a Mediterranean Diet Score (MDS). Odds ratios (OR) and 95% confidence intervals (CI) were calculated for semen volume <1.5 mL, sperm concentration <15 mil/mL, and total count <39 mil. RESULTS: Three hundred nine men, age range 27-60, were enrolled: 19.3% had semen volume < 1.5 mL, 30.5% sperm concentration <15 mil/mL, and 32.1% total count <39 mil. MDS was low (0-3) in 86 men (27.8%), intermediate (4-5) in 131 (42.4%), and high (6-9) in 92 (29.8%). Semen volume was not associated with MDS. Compared to the highest MDS category (6-9), the ORs for low sperm concentration were 1.34 (95% CI 0.69-2.50) for MDS 4-5 and 2.42 (95% CI 1.21-4.83) for MDS 0-3, with significant trend (p = 0.011). The corresponding estimates for total count were 1.26 (95% CI 0.66-2.42) and 2.08 (95% CI 1.05-4.12), with significant trend (p = 0.034). These findings were consistent in strata of history of reproductive organ diseases. CONCLUSIONS: Mediterranean Diet Score was positively associated with normal sperm concentration and total count, but not with semen volume.

RESUMO

Attention and emotion have a positive impact on memory formation, which is related to the activation of the noradrenergic system in the brain. The hippocampus and amygdala are fundamental structures in memory acquisition, which is modulated by noradrenaline through the noradrenergic receptors. Pharmacological studies suggest that memory acquisition depends on the action of both the ß3 (ß3-AR) and ß2 (ß2-AR) receptor subtypes. However, the use of animal models with specific knockout for the ß3-AR receptor only (ß3-ARKO) allows researchers to more accurately assess its role in memory formation processes. In the present study, we evaluated short- and long-term memory acquisition capacity in ß3-ARKO mice and wild-type mice at approximately 60 days of age. The animals were submitted to the open field test, the elevated plus maze, object recognition, and social preference. The results showed that the absence of the ß3-AR receptor caused no impairment in locomotion and did not cause anxious behavior, but it caused significant impairment of short- and long-term memory compared to wild-type animals. We also evaluated the expression of genes involved in memory consolidation. The mRNA levels for GLUT3, a glucose transporter expressed in the central nervous system, were significantly reduced in the amygdala, but not in the hippocampus of the ß3-ARKO animals. Our results showed that ß3-AR was involved in the process of acquisition of declarative memory, and its action may be due to the facilitation of glucose absorption in the amygdala.

RESUMO

BACKGROUND: The association between alcohol intake and male reproductive function is still controversial. In the frame of a prospective cohort study, designed to investigate the relation between life style and fertility, we performed a cross-sectional analysis of semen quality. METHODS: Men of subfertile couples, referring to an Italian Infertility Unit and eligible for assisted reproductive techniques (ARTs), were asked about their lifestyle: BMI, smoking, caffeine intake, occupational and leisure physical activity (PA) and alcohol intake in the last year before ART procedure. Semen volume, sperm concentration, total sperm count and sperm motility were determined. Age, risk factors for impaired male fertility, caffeine, smoking, leisure PA, days of abstinence and daily calories intake were accounted for in the analyses. RESULTS: Between September 2014 and December 2016, we enrolled 323 male patients, mean age 39.3 years. Thirty-one (9.6%) were abstainers, 97 (30.0%) drank <1-3, 98 (30.3%) 4-7 and 97 (30.0%) ≥8 alcohol units per week. As compared to men drinking <1-3 units per week, median semen volume was higher in the 4-7 units/week group (3.0 mL, interquartile range, IQR, 2.0-4.0 vs. 2.4 mL, IQR 1.7-3.5), as well as total sperm count (87.9 mil/mL, IQR 20.2-182.1 vs. 51.5 mil/mL, IQR 15.2-114.7). Association with sperm concentration was also significant, with a U-shaped trend in groups of alcohol intake. After adjusting for potential confounders, these relations were confirmed. Similar patterns were observed in subgroups of leisure PA and risk factors for impaired male fertility, although these estimates often lacked statistical significance, presumably because of low sample size. CONCLUSIONS: Moderate alcohol intake appears positively associated to semen quality in male partners of infertile couples undergoing ARTs.

RESUMO

Secondary tracheoesophageal puncture (TEP) with voice prosthesis placement represents one of the possibility to restore vocal function after total laryngectomy. However, some patients have comorbidities that contraindicate general anesthesia. In our department, an in-clinic TEP procedure for retrograde voice prosthesis placement was developed. It allows the immediate placement of the prosthesis and the avoidance of the use of dilators. We described our technique with advantages and pitfalls. The Provox Vega Puncture Set was used. Our technique for in-clinic secondary TEP without general anesthesia or target controlled infusion was a safe and effective procedure. It allows the use of the traditional TEP set, with possibility of voice prosthesis placement after previous TEP closure.

RESUMO

BACKGROUND: To promote justice in research practice and rectify health disparities, greater diversity in research participation is needed. Lack of trust in medical research is one of the most significant obstacles to research participation. Multiple variables have been identified as factors associated with research participant trust/mistrust. A conceptual model that provides meaningful insight into the interplay of factors impacting trust may promote more ethical research practice and provide an enhanced, actionable understanding of participant mistrust. METHODS: A structured survey was developed to capture attitudes toward research conducted in emergency situations; this article focuses on items designed to assess respondents' level of trust or mistrust in medical research in general. Community-based interviews were conducted in English or Spanish with 355 New York City residents (white 42%, African American 29%, Latino 22%). RESULTS: Generally favorable attitudes toward research were expressed by a majority (85.3%), but many respondents expressed mistrust. Factor analysis yielded four specific domains of trust/mistrust, each of which was associated with different demographic variables: general trustworthiness (older age, not disabled); perceptions of discrimination (African American, Latino, Spanish language preference); perceptions of deception (prior research experience, African American); and perceptions of exploitation (less education). CONCLUSIONS: The four domains identified in the analysis provide a framework for understanding specific areas of research trust/mistrust among disparate study populations. This model offers a conceptual basis for the design of tailored interventions that target specific groups to promote trust of individual researchers and research institutions as well as to facilitate broader research participation.

RESUMO

Semen quality and male fertility are declining worldwide. As it was observed that physiologic and pathologic processes of spermatogenesis can be influenced by diet, the relation between dietary habits and semen parameters has been the focus of much interest. To review the human observational studies on this issue, we performed a systematic literature search, up to November 2016 (MEDLINE and EMBASE). We included all observational full-text papers reporting the relation between dietary habits and semen parameters. Article selection was carried out in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Twenty-three observational studies were included. Overall, 8477 healthy men and 1204 men presenting at Fertility Clinics were included in the selected studies. Even if some inconsistencies are present, possibly due to the different effect of nutrients in fertile and infertile men, results support the hypothesis that diets including fruit and vegetables, for their contents in vitamins, and fish or low-fat dairy products as the main source of proteins, are associated with better semen quality. Recommendations may be confidently provided because of the many beneficial effects of a healthy diet, although further studies are needed to clarify the currently inconsistent findings and to shed light on the underlying mechanisms.

RESUMO

BACKGROUND AND PURPOSE: Juvenile- or adult-onset forms of severe 5,10-methylenetetrahydrofolate reductase (MTHFR) deficiency manifesting as complicated hereditary spastic paraplegia have rarely been described. METHODS: Two siblings with mental retardation developed a progressive spastic paraparesis in their late teens. Their diagnostic assessment included extensive neurophysiologic, neuroimaging and metabolic studies. RESULTS: Brain magnetic resonance imaging showed occipital white matter alterations, and electromyography documented a mixed polyneuropathy. Severe hyperhomocisteinemia (>150 µmol/L) associated with the characteristic amino acid profile suggested a diagnosis of severe MTHFR deficiency, confirmed by MTHFR direct sequencing. Treatment with betaine and vitamins benefitted patients' symptoms and diagnostic features. CONCLUSIONS: Severe MTHFR deficiency can be a rare, treatable cause of autosomal recessive complicated hereditary spastic paraplegia. Its screening should be part of the diagnostic flowchart for these disorders.

RESUMO

Pain related to the osseous thoracolumbar spine is common in the equine athlete, with minimal information available regarding soft tissue pathology. The aims of this study were to describe the anatomy of the equine SSL and ISL (supraspinous and interspinous ligaments) in detail and to assess the innervation of the ligaments and their myofascial attachments including the thoracolumbar fascia. Ten equine thoracolumbar spines (T15-L1) were dissected to define structure and anatomy of the SSL, ISL and adjacent myofascial attachments. Morphological evaluation included histology, electron microscopy and immunohistochemistry (S100 and Substance P) of the SSL, ISL, adjacent fascial attachments, connective tissue and musculature. The anatomical study demonstrated that the SSL and ISL tissues merge with the adjacent myofascia. The ISL has a crossing fibre arrangement consisting of four ligamentous layers with adipose tissue axially. A high proportion of single nerve fibres were detected in the SSL (mean = 2.08 fibres/mm2 ) and ISL (mean = 0.75 fibres/mm2 ), with the larger nerves located between the ligamentous and muscular tissue. The oblique crossing arrangement of the fibres of the ISL likely functions to resist distractive and rotational forces, therefore stabilizing the equine thoracolumbar spine. The dense sensory innervation within the SSL and ISL could explain the severe pain experienced by some horses with impinging dorsal spinous processes. Documentation of the nervous supply of the soft tissues associated with the dorsal spinous processes is a key step towards improving our understanding of equine back pain.

RESUMO

OBJECTIVE: To collate clinical evidence on the use of a native collagen matrix dressing, consisting of a fibrillary collagen network, in patients with a variety of chronic wounds. METHOD: Patients whose wounds had not improved in the eight weeks before the beginning of the evalutaion were recruited. All participants had their dressings changed twice weekly and received standard adjunctive wound care as part of their treatment. Data, collected over a 4-week period, included: patient demographics, wound surface area measurements, Bates-Jensen score, level of wound pain, wound infection status, wound bed preparation staging score, depth of wound according to tissue type, and photographic imaging of patients' wounds. RESULTS: We recruited 19 patients with 20 wounds and a mean wound duration of 66.6 months (range: 4-480 months). There was a mean decrease in wound surface area of 29% (median reduction: 47%). A reduction in the Bates-Jensen score was demonstrated in 85% of cases. Wound pain reduced by 66.66% and the wound bed preparation score reduced in 16 wounds with four remaining static. No adverse events arose. CONCLUSION: This case series provides clinical evidence on the use of a native collagen matrix dressing in the management of hard-to-heal wounds that have previously received local standard therapy. The decrease in wound surface area together with other data indicating improved wound status suggests that a native collagen matrix dressing supports healing and improves quality of life through reduction in wound pain.
