RESUMEN
INTRODUCTION: Although nerves and vessels of the penis play important role in erection, there are few studies on their development in human fetus. Therefore, the objective of the present study is to analyze, quantitatively, in the corpora cavernosa and corpus spongiosum, the development of the nerves and vessels in the fetal penis at different gestational ages. MATERIAL AND METHODS: Fifty-six fresh, macroscopically normal human fetuses aged from 13 to 36 weeks post-conception (WPC) were used. Gestational age was determined by the foot length criterion. Penises were immediately fixed in 10% formalin, and routinely processed for paraffin embedding, after which tissue sections from the mid-shaft were obtained. We used immunohistochemical staining to analyze the nerves and vessels in the corpus cavernous and in the corpus spongiosum. These elements were identified and quantified as percentage by using the Image-J software. RESULTS: The quantitative analysis showed that the percentage of nerves varied from 3.03% to 20.35% in the corpora cavernosa and from 1.89% to 23.88% in the corpus spongiosum. The linear regression analysis indicated that nerves growth (incidence) in the corpora cavernosa and corpus spongiosum correlated significantly and positively with fetal age (r2=0.9421, p<0.0001) and (r2=0.9312, p<0.0001), respectively, during the whole fetal period studied. Also, the quantitative analysis showed that the percentage of vessels varies from 2.96% to 12.86% in the corpora cavernosa and from 3.62% to 14.85% in the corpus spongiosum. The linear regression analysis indicated that vessels growth (appearance) in the corpora cavernosa and corpus spongiosum correlated significantly and positively with fetal age (r2=0.8722, p<0.0001) and (r2=0.8218, p<0.0001), respectively, during the whole fetal period studied. In addition, the linear regression analysis demonstrated a more intense growth rate of nerves in the corpus spongiosum during the 2nd trimester of gestation, when compared with nerves in the corpora cavernosa. In addition, the linear regression analysis demonstrated a more intense growth rate of vessels in the corpus spongiosum when compared with the corpora cavernosa, during the whole fetal period studied. CONCLUSIONS: In the fetal period, the human penis undergoes major developmental changes, notably in the content and distribution of nerves and vessels. We found strong correlation between nerves and vessels growth (amount) with fetal age, both in the corpora cavernosa and corpus spongiosum. There is significant greater proportional number of nerves than vessels during the whole fetal period studied. Also, nerves and vessels grow in a more intense rate than that of the corpora cavernosa and corpus spongiosum areas.

Objective: Using a salutogenic approach, this study aimed to identify similarities in the protective factors of nurses' psychological Quality of Life (QoL) and professional wellbeing (PWB) in four countries and to assess their variability over time during the COVID-19 pandemic. Methods: This multicentric study used a longitudinal design with three measurements points: Autumn 2021, spring 2022, and autumn 2022. The study consisted in a self-administered online questionnaire addressed to nurses working in hospitals. Across all measurement times, 3,310 observations were collected in France, 603 in Switzerland, 458 in Portugal, and 278 in Canada. The outcomes were psychological QoL and PWB, and several potential protective factors were used as determinants. Results: Analyses revealed few changes over time in the outcomes. Across all countries, psychological QoL was associated positively with resilience and perceived social support, whereas PWB was associated positively with the ability to provide quality work and support from colleagues and superiors. Conclusion: The findings of this study highlighted the potential of several factors protective of nurses' psychological QoL and PWB. These should be fostered through policies and measures to support nurses.

Lynch syndrome is the most common cause of hereditary colorectal cancer. It usually develops asymptomatically until symptoms related to colorectal carcinoma appear, such as gastrointestinal bleeding, abdominal pain, and changes in bowel habits and/or stool characteristics. Oftentime, when these clinical signs and symptoms are not present, the diagnosis becomes challenging. We present the clinical case of a 69-year-old woman, adopted, with no known previous history, who presented to the emergency department with low back pain, without irradiation, that had been going on for three days, associated with inflammatory signs in the right hip region. There were no urinary or sensory alterations and no recent trauma. She was initially discharged with antibiotherapy with the diagnosis of hip cellulitis. As the symptoms continued and the inflammation spread to the right lower limb, she returned to the emergency department. A CT scan revealed an abscess (17 cm) in the right buttock, complicated by necrotizing fasciitis due to fistulization from a tumor in the right colon. She underwent an exploratory laparotomy, which identified a neoplasm of the ascending colon, adherent to the abdominal wall, in the right lumbar region. Right hemicolectomy and drainage of the right buttock/thigh abscess were performed. The histology was compatible with invasive adenocarcinoma, with high-grade dysplasia but well differentiated, pT3G1N0. The immunohistochemistry was suggestive of Lynch syndrome.
RESUMEN
BACKGROUND: Although many studies analyse gender differences in the clinical expression of Attention-Deficit Hyperactivity Disorder (ADHD) and prevalence studies show that girls with ADHD are underdiagnosed, there are no instruments that are sensitive to the detection of girls with ADHD. OBJECTIVE: The objective of this study is to develop a self-report early detection instrument for boys and girls with ADHD aged 7 to 16, which includes the gender perspective and is sensitive to the detection of girls with ADHD. METHODS: The scale was developed and the items that comprised it were created from the thematic analysis of ADHD and its evaluation in children based on the diagnostic criteria of the DSM-5-TR. A modified e-Delphi method involving a three-round web survey was used to establish a consensus on the content of the scale. Ten experts were recruited to form a professional panel. The panel members were asked to assess the differential symptomatology of ADHD in boys and girls, the dimensions to be evaluated, and the importance of scale items to evaluate the content. RESULTS: A consensus was reached regarding 13 total items distributed in three dimensions: inattention; hyperactivity/impulsivity; and, a third dimension, internalisation, which includes symptoms most present in the expression of ADHD in girls. CONCLUSIONS: To the best of our knowledge, the development of this scale using the Delphi method is the first specific scale used for identifying ADHD that also addresses the gender perspective and the differential symptomatology between boys and girls. However, we must proceed to the analysis of psychometric properties, as the scale requires an exhaustive study of its reliability and validity. We can anticipate that this scale will provide relevant and reliable information that can be used for the identification of ADHD in both boys and girls.
RESUMEN
PURPOSE: The gubernaculum seems to be the most important anatomical structure in the testicular migration process. The objective of this paper is to review current literature regarding the role of gubernaculum testis nerves in testicular migration. We conducted a comprehensive literature review about the gubernaculum testis innervation. A PubMed database search was performed in April 2024, focusing on gubernaculum testis and cryptorchidism and genitofemoral nerve (GFN) and calcitonin gene-related peptide (CGRP) gene. The gubernaculum has its own nerve supply, the GFN, descending on the anteromedial surface of the psoas muscle from L1-L2 segments. The second phase of testicular descent is regulated by androgens and CGRP, released from the sensory nucleus of the GFN. The GFN doesn't directly play a role in testicular migration but there is a theory that shows a regulatory function of this nerve in hormonal action during this process. The gubernaculum testis has important structural alterations during the testicular migration and the genitofemoral nerve and CGRP gene are of great importance in this process. The genitofemoral nerve provides motor innervation to the cremaster muscle and gubernaculum, which helps regulate the position of the testes within the scrotum.

BACKGROUND: Right ventricular impairment is common among patients undergoing transcatheter edge-to-edge repair for secondary mitral regurgitation (SMR). Adherence to guideline-directed medical therapy (GDMT) for heart failure is poor in these patients. OBJECTIVES: The aim of this study was to evaluate the impact of GDMT on long-term survival in this patient cohort. METHODS: Within the EuroSMR (European Registry of Transcatheter Repair for Secondary Mitral Regurgitation) international registry, we selected patients with SMR and right ventricular impairment (tricuspid annular plane systolic excursion ≤17 mm and/or echocardiographic right ventricular-to-pulmonary artery coupling <0.40 mm/mm Hg). Titrated guideline-directed medical therapy (GDMTtit) was defined as a coprescription of 3 drug classes with at least one-half of the target dose at the latest follow-up. The primary outcome was all-cause mortality at 6 years. RESULTS: Among 1,213 patients with SMR and right ventricular impairment, 852 had complete data on medical therapy. The 123 patients who were on GDMTtit showed a significantly higher long-term survival vs the 729 patients not on GDMTtit (61.8% vs 36.0%; P < 0.00001). Propensity score-matched analysis confirmed a significant association between GDMTtit and higher survival (61.0% vs 43.1%; P = 0.018). GDMTtit was an independent predictor of all-cause mortality (HR: 0.61; 95% CI: 0.39-0.93; P = 0.02 for patients on GDMTtit vs those not on GDMTtit). Its association with better outcomes was confirmed among all subgroups analyzed. CONCLUSIONS: In patients with right ventricular impairment undergoing transcatheter edge-to-edge repair for SMR, titration of GDMT to at least one-half of the target dose is associated with a 40% lower risk of all-cause death up to 6 years and should be pursued independent of comorbidities.

Right ventricle-pulmonary artery (RV-PA) coupling has been linked to clinical outcomes in patients with severe aortic stenosis (AS) undergoing transcatheter valve implantation (TAVI). However, the best timing for prognostic assessment remains uncertain. Our aim was to determine the impact of RV longitudinal function parameters and RV-PA coupling on mortality in patients undergoing TAVI. Retrospective, single center, analysis including patients with AS who underwent TAVI between 2007 and 2021. Echocardiographic evaluation was performed before, shortly after the procedure, and during follow-up. RV-PA uncoupling was defined as a TAPSE/PASP ratio<0.55 (severe RV uncoupling was defined as TAPSE/PASP ratio<0.32. The effect of RV parameters on all-cause mortality up to 12 months was assessed. Among the 577 patients included, pre-procedural TAPSE/PASP ratio data were available for 205. RV-PA uncoupling was present in 113 patients (55.1%), with severe uncoupling observed in 31 (15.1%). Within the first 12 months after TAVI, 51 patients (9%) died. Severe RV-PA uncoupling was associated with mortality in univariable Cox regression; however, this association was lost after adjusting for EuroSCORE II. A significant association was found between the TAPSE/PASP ratio (per 0.1-unit increase) after the procedure and the primary endpoint (HR: 0.73; 95% CI: 0.56, 0.97; p=0.029). Higher postprocedural PASP (HR: 1.04; 95% CI: 1.02, 1.06; p<0.001 was also associated with all-cause mortality. V-PA uncoupling and PASP after TAVI are associated with all-cause mortality in patients and may be valuable for patient selection and for planning post-procedural care.

RESUMEN
INTRODUCTION: Studies suggest increased likelihood of atrial fibrillation (AF) recurrence after catheter ablation (CA) in women than in men, indicating that sex may be an independent risk factor for recurrence. Nevertheless, the influence of sex on AF recurrence and underlying mechanisms remains unclear. METHODS: Retrospective, single-centre study including patients undergoing AF CA between 2017 and 2021. Late recurrence (LR) was defined as AF recurrence ≥90 days after ablation, whereas early recurrence (ER) occurred within 90 days. RESULTS: 656 patients (32% women) were included, with a median follow-up period of 26 months. Compared to men, women undergoing CA were older, had higher body mass indexes, and had higher rates of hypertension, thyroid dysfunction, and valvular disease. Women also had increased LR risk after CA (HR 1.76, 95% CI [1.19, 2.59]). A time-split multivariable analysis at one year of follow-up showed no difference in LR risk during the first 12 months after CA (HR 1.19, 95% CI [0.73, 1.94]); however, LR risk increased in women (HR 2.90, 95% CI [1.68, 5.01]) after 12 months. In a sex-stratified analysis, coronary calcium score (CCS) >100 was associated with increased LR risk in men (HR 1.81, 95% CI [1.06, 3.08]), but not in women. Cardiac adipose tissue volume was not associated with increased LR risk. CONCLUSIONS: Fewer women underwent CA than men and LR was more frequent in women, particularly one year after the procedure. CCS was associated with increased LR risk in men.

BACKGROUND: Eco-anxiety is increasingly recognized as a shared experience by many people internationally, encompassing fear of environmental catastrophe and anxiety about ecological crises. Despite its importance in the context of the changing climate, measures for this construct are still being developed in languages other than English. METHODS: To contribute to global eco-anxiety research, we translated the Hogg Eco-Anxiety Scale (HEAS) into Spanish, creating the HEAS-SP. We validated this measure in samples from both Argentina (n = 990) and Spain (n = 548), performing measurement invariance and confirmatory factor analyses. Internal consistency of the scale and score stability over time were investigated through reliability analyses. Differences in eco-anxiety across sociodemographic variables were explored through Student's t-tests and Pearson's r tests. RESULTS: The four-factor model of the HEAS-SP comprising affective and behavioural symptoms, rumination, and anxiety about personal impact demonstrated excellent model fit. We found good internal consistency for each subscale, and established measurement invariance between Spanish and Argentine samples, as well as across genders and participants' age. Spanish participants reported higher scores on the affective symptoms and personal impact anxiety factors compared to the Argentinian sample. Also, men reported lower levels than women on the subscales of affective symptoms, rumination, and personal impact anxiety. It was found that the relationship between both age and personal impact anxiety and age and affective symptoms varies significantly depending on the gender of the individuals. Younger participants tended to report higher scores on most dimensions of eco-anxiety. CONCLUSIONS: These findings enhance the global initiative to investigate, explore and therefore comprehend eco-anxiety by introducing the first valid and reliable Spanish-language version of this psychometric instrument for its use within Spanish and Argentinian populations. This study augments the body of evidence supporting the robust psychometric properties of the HEAS, as demonstrated in prior validations for Australian, Turkish, Portuguese, German, French, and Italian populations.

This study delves into how motivational sessions and brief interventions impact students' alcohol consumption, highlighting the vital role of nurses in fostering positive behavioural changes. The study aims to discern the effects of these interventions, starting with a pre-and post-intervention setup involving 62 students from a private school in northern Portugal. The intervention comprised a session delivered by school and mental health nurses, utilizing the motivational intervention and FRAMES method and a poster offering feedback on alcohol consumption scores. The results indicated that females tended to drink for fewer days and engage in less binge drinking than males. Furthermore, the intervention hinted at a reduction in the number of heavy drinking days. This study underscores the importance of including healthcare professionals, particularly nurses, in delivering brief interventions within school settings. The findings carry weight for crafting evidence-based interventions to cultivate healthier adolescent behaviours and enhance overall well-being.
RESUMEN
PURPOSE: To evaluate, by quantitative and qualitative methods, the glomerular ultrastructure in Wistar rats fed a cafeteria diet. METHODS: Male Wistar rats were divided into two groups at 21 days of age: control (C, n = 10) and cafeteria diet (CAF, n = 8). The animals were followed up until 5 months of age, followed by euthanasia. The blood, kidneys, and fat deposits--epididymal, retroperitoneal, and subcutaneous--were extracted and analyzed. Data were analyzed by Student's t test, and p < 0.05 was considered statistically significant. RESULTS: The cafeteria diet promoted glucose intolerance, hyperglycemia (p < 0.0001), and deposition of retroperitoneal fat (p < 0.005). Scanning electron microscopy revealed that the length of the foot process was similar in both groups. The quantitative analyses by transmission electron microscopy revealed that the cafeteria diet reduced the thickness of the glomerular basement membrane (p < 0.05). CONCLUSIONS: The intake of lipids and simple carbohydrates were found to be associated with alteration in the glomerular ultrastructure. However, more studies are needed to evaluate not only the effects of high-protein and high-fat diets on components of the glomerular filtration barrier, but also renal physiology.

ABSTRACT Objective: To evaluate the surgical anatomy of the kidney collecting system through a narrative review of the literature, highlighting its importance during diagnosis and its approach during surgical procedures for the treatment of renal stones. Material and Methods: We carried out a review about the anatomy of the kidney collecting system. We analyzed papers published in the past 40 years in the databases Pubmed, Embase and Scielo, and we included only papers in English and excluded case reports, editorials and opinions of specialists. Results: Renal collecting system could be divided in four groups: A1 - kidney midzone (KM), drained by minor calyx that are dependent on the superior or the inferior caliceal groups; A2 - KM drained by crossed calyx, one draining into the superior caliceal group and another draining into the inferior caliceal group; B1 - KM drained by a major caliceal group independent of both the superior and inferior groups; and B2 - KM drained by minor calyx entering directly into the renal pelvis. Some details and anatomic variations of the collecting system are related to clinical and radiological aspects, particularly perpendicular calyces, interpyelocalyx space, position of calyces in relation to renal border, classification of the renal collecting system, infundibular diameter and the angle between the lower infundibulum and renal pelvis. Conclusion: The knowledge of intra-renal collecting system divisions and variations as the angle between the renal pelvis and lower infundibula, position of the calices in relationship with renal edge and the diameter and position of the calyces are important for the planning of minimally invasive renal surgeries.
RESUMEN
Twisted testicular appendages had difficult differential diagnosis with testicular torsion. The objective of this paper is to evaluate the number, shape, size and determine the laterality pattern of the testicular and epididymal hydatids and evaluate the correlations between the length and width of the testicular and epididymal hydatids with testicular measurements. We analyzed 60 fixed cadavers and 16 patients with prostate cancer without previous hormonal treatment undergoing bilateral orchiectomy, totalizing 76 units and 152 testicles. In relation to the testicular appendices, we analyzed the following situations: absence of testicular and epididymis appendages, presence of a testicular appendix, presence of epididymis appendix, and presence of testicular and epididymis appendix. We measured the length, width and thickness of the testis and classified the appendages as sessile or pedicled. Chi-square test was used to verify associations between categorical variables. McNemar Test was used to verify differences between the percentages of right and left appendages. Correlations between quantitative measures were evaluated using the Pearson Correlation Coefficient (p < 0.05). In 50 cases (65.78%) we observed the presence of some type of appendices, in 34 cases (44.72%) we observed the presence of testicular appendices and in 19 cases (25%) the presence of epididymal appendices. We observed the presence of pedicled appendices in 39 cases (51.32%), with 25 of the cases (32.89%) of pedicled testicular appendices and 14 of the cases (18.42%) of pedicled epididymal appendages, with a significant association between the occurrence of appendices on the right and left sides (p < 0.001). Testicular hydatids were present in around two thirds of our sample being pedunculated in almost half of the cases with bilateral similarity. There is a significant chance in cases of twisted appendices that the same anatomical characteristics are present on the opposite side, which is a factor that tends to indicate the need for contralateral surgical exploration in cases of torsion, however studies with larger samples are needed to confirm these findings.

BACKGROUND: The following protocol pertains to a pioneer study, aiming to investigate how weather sensitivity and walking in different environments affects the psychophysiological responses to the stress of individuals with coronary artery disease (CAD) during rehabilitation (WE_SENSE_THE_NATURE). This randomised control trial will provide fresh insight on the influence of the environmental exposure in CAD patients, as it is seldom investigated in association to the disease. Additionally, findings on the link between personality traits and cognitive functions (especially cognitive flexibility), and weather sensitivity may help reveal a fine-grained perspective on the treatment possibilities for individuals with CAD at risk to stress-vulnerability. METHODS: The proposed protocol is for a randomised control trial among individuals attending a cardiac rehabilitation program. We aim to recruit 164 individuals, collecting information related to demographic characteristics, weather sensitivity, functional capacity, personality traits, subjective mental health status, cognitive function, and basal cortisol level of participating individuals. Basal cortisol level refers to cortisol concentration in saliva and will be tested in the morning and the afternoon prior to the day of the experiment. After baseline measurements, the patients will be randomly assigned to either walking outdoors or walking indoors. All measures and their sequential order will remain the same within each group, while the treatment condition (i.e., walking environment) will vary between groups. On the day of the experiment, hemodynamic parameters (assessed via 6-hour blood pressure measurements), stress level (consisting of assessments of cortisol level), and mood (assessed using visual analogues scale) will be registered. Cold stress test will be administered to evaluate the effect of walking in different environments. DISCUSSION: The outcomes of this study may have direct clinical applications for the use of different types of exercise environments in cardiac rehabilitation programs. Awareness about the potential influence of weather sensitivity on the psychophysiological reactions to stress in individuals with CAD may contribute to a timely planning and implementation of actions leading to improved medical care services and preventive measures, especially considering the expected weather oscillations and extreme weather events due to unfolding of the climate change. TRIAL REGISTRATION: This protocol has been retrospectively registered in ClinicalTrials.gov with identifier code: NCT06139705 on November 20, 2023.

BACKGROUND: The relationship between the nurse and the patient with mental health disorder is crucial to the recovery process. Thus, patients with mental health disorders should be active subjects in this relationship by having autonomy and self-determination. METHODS: This study aimed to explore the perspectives of adult patients with mental health disorders on the relationship with nurses. A qualitative, descriptive, and exploratory study was conducted in March 2023, using focus group meetings in an association to support patients with severe mental health disorders in the Northern region of Portugal. The study followed the Consolidated Criteria for Reporting Qualitative Research (COREQ). A total of 8 patients participated in the study. Two focus group meetings were conducted. The inductive method was used, and content analysis of the transcripts was performed. The QDA Miner Lite 4.0 and Microsoft Excel were used for content analysis. RESULTS: Participants considered the relationship with nurses important for their recovery and expected nurses to provide support and help, being able to identify their needs, thus personalising their care. Attitudinal and communication aspects were also considered crucial for establishing a solid, trusting, and meaningful relationship. CONCLUSION: According to the findings nursing care is expected to focus on the patient, his/her preferences, expectations, and the uniqueness of each individual. The results of this study may be useful for the reflection and improvement of nurses in their relational and communication skills and the driving force for nursing students' awareness of the perspective of the relationship with patients with mental health disorder and its relevance.
RESUMEN
Exposure to prolonged stress in pregnancy and/or lactation can lead to the future development of diseases. We aimed to study the effects of maternal stress on the biometry, metabolism, and penile morphology of young Wistar rats. Animals were divided into two experimental groups: Control Group (C) - pups from control mothers, without any intervention (n=5); and Chronic Stress Group (S) - pups from mothers who suffered variable stress in the third week of pregnancy (14th to 21st day; n=5). Food intake and body mass of the pups (n=10, in the C group and n=9 in the S group) were checked; at euthanasia (three months old), fat deposits and penis were removed. At birth and weaning, S animals were lighter than C animals, [-33.72% (p=0.0422) and -17.07% (p=0.0018)], respectively. However, the final body mass and body mass delta showed no differences. Food intake and fat deposits also did not differ. However, the S group was hyperglycemic at 30 and 60 days of life [+20.59% (p=0.0042) and +14.56% (p=0.0079), respectively], despite the glycemia measured at 90 days showing no difference between groups. Penile areas and surface densities of the corpora cavernosa components were similar between groups. The results indicate that maternal stress is an important metabolic programmer, which generates low birth weight and accelerated recovery of body mass after birth (catch-up). However, in an early analysis (90 days of life), exposure to gestational stress did not change the morphology of the offspring's penis in adulthood.
