Active production of music as distraction for venipuncture in children and adolescents: a randomized clinical trial.

More than 50% of children report considerable pain during venipuncture or intravenous cannulation. Despite the tools and techniques may be employed to reduce pain and distress in everyday clinical practice, the care offered is frequently insufficient. Music's potential effect in healthcare settings has received increasing attention. This study aimed to verify if the active production of music with a Leap Motion Controller could help decreasing pain and distress during venipuncture in children and adolescents. We conducted an open-label randomized controlled clinical trial with parallel arms. Children aged 8 to 17 were enrolled at the blood-drawing center of the Institute for Maternal and Child Health IRCCS Burlo Garofolo of Trieste, Italy. We hypothesized that in order to demonstrate an adequate improvement in the pain score in the intervention group, at least 200 children, 100 in each group, were needed, with alpha 5% and 1-beta 80%. Differences between the groups were evaluated with the nonparametric Mann-Whitney U-test. The subjects were randomly assigned either to the active production of music group or to the standard of care group. The primary outcome was the median self-reported procedural pain score between experimental and standard of care group. Secondary outcomes were: the median pain and distress scores according to parental judgment and operators' judgment between the experimental and control group. Three hundred subjects entered the study and were randomized, 150 in the active production of music group and 150 in the standard of care group. Median self-reported pain scores were 1 (0-2) in the active production of music group and 2 (1-2) in the standard of care group and this difference was statistically significant (p = 0.0016). Median procedural distress was 1 (0-3) in the active production of music group and 3 (1-6) in the standard of care group, according to parental judgment, and this difference was statistically significant (p = 0.0000016). CONCLUSION: This research showed that the active production of music is a valuable distraction technique to decrease venipuncture related pain and distress in children and adolescents. TRIAL REGISTRATION: The study protocol was registered with ClinicalTrial.gov (June 28[th] 2022, NCT05441241) before the start of the subjects' enrolment. WHAT IS KNOWN: • The benefits of music on pain and anxiety are well known and have been tested during different painful procedures. • The effect of active production of music has never been tested in children during venipuncture. WHAT IS NEW: • In our study median self-reported pain scores and median procedural distress, according to parental judgment, were lower in the active production of music group than in the standard of care group and these differences were statistically significant.

Bone quality in relation to skeletal maturation in palatal miniscrews insertion sites.

INTRODUCTION: This study aimed to investigate the relationship between bone density and quantity at the insertion sites of palatal miniscrews and skeletal maturation-evaluated with the middle phalanx maturation method-in growing patients. METHODS: Sixty patients were analyzed as having a staged third finger middle phalanx radiograph and a cone-beam computed tomography of the maxilla. On the cone-beam computed tomography, a grid was designed to parallel the midpalatal suture (MPS) and posterior to the nasopalatine foramen, both on the palatal and lower nasal cortical bones. Bone density and thickness were measured at the intersections, and medullary bone density was also calculated. RESULTS: Of patients in MPS stages 1-3, 67.6% showed a mean palatal cortical thickness of <1 mm, whereas in 78.3% of the patients in stages 4 and 5, it was >1 mm. The nasal cortical thickness showed a similar trend (MPS stages 1-3: 62.16% <1 mm; MPS stages 4 and 5: 65.2% >1 mm). There was a significant difference in the density of the palatal cortical bone between MPS stages 1-3 (1272.05 ± 191.13) and stages 4 and 5 (1572.33 ± 274.89) and in nasal cortical density between MPS stages 1-3 (1428.09 ± 198.97) and stages 4 and 5 (1597.97 ± 267.75) (P <0.001). CONCLUSIONS: This study revealed a correlation between skeletal maturity and maxillary bone quality. MPS stages 1-3 have lower palatal cortical bone density and thickness but high nasal cortical bone density values. MPS stage 4 and, even more, stage 5 show increasing palatal cortical bone thickness and palatal and nasal cortical bone density values.

Serological and cellular response to mRNA-SARS-CoV2 vaccine in patients with hematological lymphoid malignancies: Results of the study "Cervax".

messenger RNA (mRNA)-Severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) vaccines such as BNT162b2 became available in late 2020, but hematological malignancy patients (HM pts) were not evaluated in initial registration trials. We hereby report the results of a prospective, unicentric, observational study Response to COVID-19 Vaccination in hEmatological malignancies (CERVAX) developed to assess the postvaccine serological and T-cell-mediated response in a cohort of SARS-CoV2-negative HM pts vaccinated with BNT162b2. Patients with lymphomas [non-Hodgkin lymphoma (NHL) and Hodgkin lymphoma (HL)], chronic lymphocytic leukemia (CLL), and multiple myeloma (MM); off-therapy for at least 3 months; in a watch-and-wait program; or in treatment with ibrutinib, venetoclax, and lenalidomide were included. Different time points were considered to assess the serological response to the vaccine: before the second dose (T1), at 3-6-12 months after the first dose (T2-3-4, respectively). Since March 2021, 39 pts have been enrolled: 15 (38%) NHL, 12 (31%) CLL, and 12 (31%) MM. There were 13 of the 39 pts (33%) seroconverted at T1; an increase of the serological response was registered after the second dose (T2) (22/39 pts, 56%) and maintained after 6 months (22/39 pts, 56%) and 12 months (24/39 pts, 61%) from the first dose (T3-T4, respectively). Non-serological responders at T4 were 7/39 (18%): 0/15 NHL, 1/12 MM (8%), and 6/12 CLL (50%). All of them were on therapy (one lenalidomide, three ibrutinib, and three venetoclax). SARS-CoV2-reactive T-cell analysis (interferon gamma release assays) was available since June 2022 and was evaluated at 12 months (T4) from the first dose of vaccine in 31/39 pts (79%). T-cell-mediated-responders were 17/31 (55%): most of them were NHL and MM (47%, 41% and 12% for NHL, MM, and CLL, respectively). Both serological and T-cell non-responders were represented by pts on active therapy (venetoclax/ibrutinib). During the period of observation, eight (20.5%) pts developed mild SARS-CoV2 infection; no coronavirus disease 19 (COVID-19)-related deaths or hospitalizations were registered. In conclusion, in our cohort of lymphoproliferative pts receiving BNT162b2, CLL diagnosis and venetoclax/ibrutinib seem to be related with a lower humoral or T-mediated response. Nevertheless, the efficacy of mRNA vaccine in HM pts and the importance to continue the vaccine program even in non-responders after the first dose are supported in our study by demonstrating that a humoral and T-cell-mediated seroconversion should be observed even in the subsets of heavily immunocompromised pts.

Knowledge and awareness of oral cancer: A cross-sectional survey in Trieste, Italy.

The aim of the study was to verify the knowledge on oral cancer and to assess possible differences in awareness and information basing on different demographic and subject-related factors. An anonymous survey was provided to 750 random subjects using online-based questionnaires. Statistical analysis was performed in order to evaluate the influence of demographic variables (gender, age, education) on knowledge of oral cancer and its risk factors. 68.4% of individuals knew about the existence of oral cancer, mostly from media and family/friends. Awareness was significantly influenced by gender and higher education, but not by age. Most participants recognized smoking as a risk factor, but alcohol abuse and sunlight exposure are less known, especially among less educated subjects. On the contrary, our study shows a diffusion of false information: more than 30% of the participants indicated the possible role of amalgam fillings in oral cancer onset, independently of gender, age or education. The results of our study suggest the need for oral cancer awareness campaigns, where school and healthcare professionals should be actively involved in promoting, organizing and finding methods to monitor the medium and long-term efficacy with proper methodological quality.

Histopathology of oral lichen planus and oral lichenoid lesions: An exploratory cross-sectional study.

OBJECTIVE: To better characterize the histopathology of oral lichen planus and oral lichenoid lesions and to highlight the differences between them in order to support the clinician in the diagnostic and therapeutic management of such conditions. SUBJECTS AND METHODS: Fifty-five patients, clinically diagnosed with oral lichen planus (n = 25) or oral lichenoid lesions (n = 30), were consecutively enrolled in the present study. Subsequently, one blind pathologist reviewed all the biopsy specimens of enrolled subjects following a specific protocol to provide a detailed histopathological description. Demographic, anamnestic, and clinical data were also recorded from all the participants. Patients' data were analysed and compared using the chi-squared test, to provide distinguishing features between the studied conditions. RESULTS: We found a higher and statistically significant number of eosinophils in the oral lichenoid lesions compared with the oral lichen planus group (p < 0.01), an equally promising result was seen regarding plasma cells, which were more represented (p = 0.05) in the oral lichenoid lesions than in the oral lichen planus cases. No statistically significant differences were detected in demographic, anamnestic and clinical data. CONCLUSION: A mixed lichenoid inflammatory infiltrate, consisting of eosinophils and plasma cells, could be used as reliable histological features for the diagnosis of oral lichenoid lesions, as long as compared with findings obtained from the patients' history and clinical examination.

How to Cope with the Ponseti Method for Clubfoot: The Families' Standpoint.

(1) Background: The Ponseti Method is the gold standard for the treatment of congenital clubfoot. It is a low-cost treatment consisting in a series of plaster casts, a percutaneous Achilles' tenotomy and a Mitchell Ponseti brace to wear with a definite protocol. This treatment allows children to be with their families instead of being hospitalized. This advantage is also a challenge for the families that have to follow the protocol at home. This paper aims to analyze the perception, the difficulties and the overcomes of the families during the treatment. (2) Methods: We used a 41 questions questionnaire by Nogueira and Morquende. Questions were answered by families who had already finished the treatment or were still following it. (3) Results: We interviewed 92 families. The worst handling phase appeared to be the cast phase, while the brace seemed more bearable. In total, 57 families overrated tenotomy; (4) Conclusions: Families perceived the Ponseti Method as a quality treatment. The anxiety about the diagnosis played a strong role, but none of the difficulties encountered decreased the treatment outcomes or affected families' adherence to the protocol. The open-ended answers highlighted that the positive relationship with doctors played a key role in the everyday compliance and the achievement of good results.

Accuracy of the digital workflow for guided insertion of orthodontic palatal TADs: a step-by-step 3D analysis.

BACKGROUND: The introduction in the orthodontic field of the digital workflow for guided insertion of palatal TADs and the development of the 1-visit protocol led to the reduction of chair time and the possibility of complete customization of designs and materials. Conversely, the reduction of operative steps implicates a lower tolerance of deviations between the planned and the actual position of the miniscrews, particularly when the orthodontic device is fixed on 4 palatal TADs or has a rigid structure. This study aims to analyze the influence of each step of the digital workflow on the deviation of the miniscrews' axis of insertion in a bicortical sample. The null hypothesis is that there are no significant differences in the deviations among the operative steps. METHODS: 33 subjects were selected for insertion of bicortical palatal miniscrews with a 1-visit protocol. Digital files were collected at the three stages of the workflow (i.e., digital planning, laboratory prototype, post-insertion impression). A 3D software analysis was performed on a total of 64 miniscrews. After automatic shape recognition of the guiding holes of the digital plan and the scanbodies of the laboratory prototype and post-insertion impression as geometric cylinders, their three-dimensional longitudinal axis was traced and the deviation among them was calculated. Friedman test with Bonferroni correction was performed to assess the significance of the deviations among the three steps, with significance set at p < 0.05. RESULTS: The laboratory step has a significantly lower degree of deviations (2.12° ± 1.62) than both the clinical step (6.23° ± 3.75) and the total deviations (5.70° ± 3.42). No significant differences were found between miniscrews inserted on the left or the right side. CONCLUSIONS: This study suggests that laboratory procedures such as surgical guide production or rapid prototyping don't play a significant role in the degree of deviations between the planned and the positioned palatal TADs. Conversely, the clinical steps have a bigger influence and need to be carefully evaluated. Despite this difference, there is a cumulative effect of deviations that can lead to the failure of the 1-visit protocol.

Incidence of Congenital Clubfoot: Preliminary Data from Italian CeDAP Registry.

(1) Background: We find the incidence of clubfoot in Italy from "Certificate of Delivery Care Registry (CeDAP)", a database of the Italian Ministry of Health, the most comprehensive public data available for this purpose. (2) Methods: The CeDAP registry is a web system that provides epidemiological and sociodemographic information about newborns. It started on 1 January 2002, following the ministerial Decree no. 349 of 16 July 2001. The certificate is structured into six sections; each collects specific information referring to the birthplace, parents, pregnancy, childbirth, newborn, and the possible presence of congenital malformations or the causes of neonatal mortality. The midwife or the doctor draws up the certificate no later than ten days after birth. Each region transmits the data every six months to the Ministry of Health. The period between 2013 and 2017 has been selected for the study, with every Italian region's data. We conducted a retrospective descriptive study. (3) Results: The overall rate in northern Italy is 1.09 (with some exceptions described), but we think it is essential to reevaluate this number again, given more accurate data collections by every Italian hospital. (4) Conclusions: This study intends to build a framework for future epidemiologic studies about clubfoot in Italy.

Pediatric males receiving hematopoietic stem cell transplant lose their male disadvantage in disease risk after the procedure: A retrospective observational study.

Sex differences play a relevant role in cancer susceptibility, incidence and survival. Exploring such differences is difficult because of the close interplay of genetic, epigenetic and hormonal factors. However, a better understanding of the role of such disparities in cancer mechanisms could improve its prevention and therapy. Our study explores how sex differences in pediatric outcomes vary after undergoing first and advanced-line therapy for hematological malignancies. The primary goal was to evaluate if sex differences in pediatric outcomes after first-line therapy persist after allogeneic hematopoietic stem cell transplantation (HSCT). The secondary goal was to analyze sex differences in disease risk at onset and pediatric outcomes after first-line therapy to compare our results with the literature's reported results. Among a total of 485 patients (280 males, 205 females) admitted for hematological malignancies, disease risk at the onset was significantly higher in males (P < .05). One hundred and seventy-four patients (111 males and 63 females) had a high-risk disease requiring HSCT. Before HSCT, all patients underwent myeloablative conditioning, which substantially impaired gonadal function. Although the number of boys undergoing HSCT was almost double that of girls, there were no sex-related differences in overall survival, cancer relapse and complications after HSCT exposure (P > .05). These findings suggest that the existing sex differences in cancer risk ab initio can be somehow flattened by a conditioning regimen, shedding new light on the role of hormonal factors in cancer mechanism and management.

Compounded glycopyrrolate is a compelling choice for drooling children: five years of facility experience.

BACKGROUND: Describe the efficacy of a galenic glycopyrrolate formulation and its impact on patients with sialorrhea Quality of Life (QoL), including costs analysis. METHODS: We performed a retrospective observational study on 21 patients who received a custom-formulated galenic glycopyrrolate syrup for sialorrhea for an average period of 14.3 months. We analyzed the telephone interviews with elaborated and validated questionnaires and the therapy costs comparing the brand marketed drug with the galenic formulation. RESULTS: Overall, 16 out of 21 patients (76.2%) reported a significant improvement in sialorrhea and QoL. In 14 subjects (66.7%), there was a remarkable decrease in the drooling severity; 10 individuals (47.6%) reported a reduction in drooling frequency. Nine patients experienced at least one adverse effect of glycopyrrolate therapy, and three of them stopped the treatment. No severe side effects were observed. The galenic drug significantly reduced costs for patients. CONCLUSIONS: An oral glycopyrrolate solution easily administered to children with brain injuries is not commercially available in many European countries. This study demonstrates the efficacy of a compounded glycopyrrolate syrup on drooling severity, frequency and ensures a better QoL in patients and their caregivers.

Combined use of rheology and portable low-field NMR in cystic fibrosis patients.

BACKGROUND: As most cystic fibrosis (CF) patients progress to respiratory failure, lung functionality assessment is pivotal. We previously developed a test that indirectly monitors airways (inflammation/functional test) by measuring the spin-spin relaxation time (T2m) of the water hydrogens present in CF sputum. Here the T2m significance in the monitoring of CF lung disease was further investigated by studying the correlation of T2m with: 1) sputum viscoelasticity, 2) mucociliary clearability index (MCI)/cough clearability index (CCI) and 3) sputum average mesh-size. METHODS: Sputum samples from 25 consenting CF subjects were analyzed by rheology tests (elastic modulus G and zero shear viscosity η0) and Low Field Nuclear Magnetic (LF-NMR) resonance (T2m). MCI/CCI were calculated from the rheological parameters. The average mesh-size (ξ) of the sputum structure was then evaluated by rheology/LF-NMR, together with FEV1 for each patient. RESULTS: There was an inverse correlation between G and η0 versus T2m, indicating that a worsening of the lung condition (T2m-FEV1 drop) is paralleled by an increase in sputum viscoelasticity (G and η0) favoring mucus stasis/inflammation. A direct correlation was also observed between T2m and MCI/CCI, showing that T2m provides information as to airway mucus clearing. Moreover, there was a direct correlation between T2m and the average sputum mesh size (ξ). CONCLUSIONS: We demonstrated a correlation between T2m (measured in CF patient's sputum) and the sputum viscoelasticity/average mesh-size and with MCI/CCI, parameters related to airway mucus clearing. Thus, the present data strengthen the potential of our test to provide indirect monitoring of airway disease course in CF patients as T2m depends on mucus solid concentration and nanostructure.

Satisfaction with online teaching of medical statistics during the COVID-19 pandemic: A survey by the Education Committee of the Italian Society of Medical Statistics and Clinical Epidemiology.

On May 2020, after 2 months of online teaching with no face-to-face lectures, the Education Committee of the Italian scientific Society of Medical Statistics and Clinical Epidemiology conceived an online survey to assess satisfaction of Italian academics of medical statistics with online teaching and remote exams. This survey highlighted teachers' perceptions as well as opportunities and limitations of online teaching of medical statistics, biostatistics, and epidemiology. Although 61% of Italian academics of medical statistics declared to be favorable to provide online teaching of medical statistics, biostatistics, and epidemiology in the future, we recognize that distance education cannot substitute the unique value of teaching and knowledge exchange that could only be transmitted through a personal interaction between students and teachers. These indications may be useful to improve the quality of the teaching process in the future.

Ruling Out Coronavirus Disease 2019 in Patients with Pneumonia: The Role of Blood Cell Count and Lung Ultrasound.

Coronavirus disease 2019 (COVID-19) is characterized by a distinctive blood leucocyte pattern and B-lines on lung ultrasound (LUS) as marker of alveolar-interstitial syndrome. We aimed to evaluate the accuracy of blood leucocyte count alone or in combination with LUS for COVID-19 diagnosis. We retrospectively enrolled consecutive patients diagnosed with community acquired pneumonia (CAP) at hospital admission to derive and validate cutoff values for blood cell count that could be predictive of COVID-19 before confirmation by the nucleic acid amplification test (NAAT). Cutoff values, generated and confirmed in inception (41/115, positive/negative patients) and validation (100/180, positive/negative patients) cohorts, were ≤17 and ≤10 cells/mm3 for basophils and eosinophils, respectively. Basophils and/or eosinophils below cutoff were associated with sensitivity of 98% (95%CI, 94-100) and negative likelihood ratio of 0.04 (95%CI, 0.01-0.11). In a subgroup of 265 subjects, the sensitivity of B-line on LUS was 15% lower (p < 0.001) than that of basophils and/or eosinophils below cutoff. The combination of B-lines with basophils and eosinophils below cutoff was associated with a moderate increase of the positive likelihood ratio: 5.0 (95%CI, 3.2-7.7). In conclusion, basophil and eosinophil counts above the generated cutoff virtually rule out COVID-19 in patients with CAP. Our findings can help optimize patient triage pending the NAAT results.

COVID-19 in the tonsillectomised population.

OBJECTIVE: Interactions between SARS-CoV-2 and pharyngeal associated lymphoid tissue are thought to influence the manifestations of COVID-19. We aimed to determine whether a previous history of tonsillectomy, as a surrogate indicator of a dysfunctional pharyngeal associated lymphoid tissue, could predict the presentation and course of COVID-19. METHODS: Multicentric cross-sectional observational study involving seven hospitals in Northern and Central Italy. Data on the clinical course and signs and symptoms of the infection were collected from 779 adults who tested positive for SARS-CoV-2, and analysed in relation to previous tonsillectomy, together with demographic and anamnestic data. RESULTS: Patients with previous tonsillectomy showed a greater risk of fever, temperature higher than 39°C, chills and malaise. No significant differences in hospital admissions were found. CONCLUSIONS: A previous history of tonsillectomy, as a surrogate indicator of immunological dysfunction of the pharyngeal associated lymphoid tissue, could predict a more intense systemic manifestation of COVID-19. These results could provide a simple clinical marker to discriminate suspected carriers and to delineate more precise prognostic models.

Modeling Postnatal Hearing Case Finding Within the Italian National Health System.

Objective: Despite the successful implementation of newborn hearing screening (NHS), a debate is emerging as to what should be the best means of enabling timely diagnosis and intervention for preschoolers with educationally significant sensorineural or conductive hearing impairment (HI) missed at the time of NHS or occurred after birth. Our study aims to document the proportion and characteristics of HIs diagnosed in children in need of audiologic assessment, in order to outline the optimization areas of an operational framework for auditory surveillance during preschool age. Method: The referral routes and outcomes of 730 audiological assessments performed in 3 years within the framework of the early hearing identification program in Trieste (Italy) were retrospectively analyzed. Results: Among 570/595 completed evaluations, an HI was diagnosed in 114 children, 73.7% of which presenting an exclusively conductive HI due to middle ear effusion. HIs were found in 36/141 who failed NHS, and 60/385 preschoolers who were referred by the primary care pediatrician's surveillance activity during well-child visits, with diagnostic yield of 25.5 and 15.5%, respectively. Conclusion: Ongoing preschool surveillance in primary care setting integrated into a NHS program is feasible to conduct and may effectively identify HIs that missed NHS or were related with a risk factor. New triage instruments and protocols for immediate audiology referral could allow to obtain the diagnosis of educationally significant conductive and sensorineural HIs ahead of the development concern and in the same way reduce patient mobility, thus optimizing timing efficiency and economic impact of the program.

Correlation of cochlear aperture stenosis with cochlear nerve deficiency in congenital unilateral hearing loss and prognostic relevance for cochlear implantation.

The use of neonatal hearing screening has enabled the identification of congenital unilateral sensorineural hearing loss (USNHL) immediately after birth, and today there are several intervention options available to minimize potential adverse effects of this disease, including cochlear implantation. This study aims to analyze the characteristics of the inner ear of a homogeneous group of congenital non-syndromic USNHL to highlight the features of the inner ear, which can help in clinical, surgical, and rehabilitative decision-making. A retrospective chart review was carried out at a tertiary referral center. Systematic diagnostic work-up and rigorous inclusion-exclusion criteria were applied to 126 children with unilateral hearing impairment, leading to a selection of 39 strictly congenital and non-syndromic USNHL cases, undergoing computed tomography (CT) and magnetic resonance (MR) imaging studies. The frequency and type of malformations of the inner ear in USNHL and unaffected contralateral ears were assessed, with an in-depth analysis of the deficiency of the cochlear nerve (CND), the internal auditory canal (IAC) and the cochlear aperture (CA). Inner ear anomalies were found in 18 out of 39 (46%) of the USNHL patients. In 1 subject, the anomalies were bilateral, and the CND resulted in the predominant identified defect (78% of our abnormal case series), frequently associated with CA stenosis. Only 3 out of 14 children with CND presented stenosis of the IAC. CND and CA stenosis (and to a much lesser extent IAC stenosis) are a frequent association within congenital and non-syndromic USNHL that could represent a distinct pathological entity affecting otherwise healthy infants. In the context of a diagnostic work-up, the evaluation with CT and MRI measurements should take place in a shared decision-making setting with thorough counseling. Both imaging techniques have proven useful in differentiating the cases that will most likely benefit from the cochlear implant, from those with potentially poor implant performance.

Long-term resveratrol treatment improves the capillarization in the skeletal muscles of ageing C57BL/6J mice.

We recently showed that the treatment with Resveratrol (RES) contrasts the effects of ageing on the skeletal muscle (SKM), reduces the appearance of tubular aggregates (TAs), and improves the fatigue resistance. Since fatigue resistance depends on the SKM capillary network, and RES has been described to improve vascularisation, we analysed the SKM capillarization in naturally ageing C57BL/6J male mice, fed with 0.04% RES in the diet for 6 months, which showed a better fatigue resistance in a previous work. Our data show an inverse correlation between the number of capillaries per fibre (CAF) and TAs in both control and treated type IIB fibres, and an increase of CAF in ageing SKM upon RES-treatment. The present work suggests that capillarization is one of the determinants of the development of TAs and fatigue resistance, and that RES can be considered a good candidate to counteract capillary rarefaction in the SKM tissue.

New Algorithm for Chest-wall Surgery and Quality of Life Assessment in Female-to-male Reassignment Patients.

BACKGROUND: Chest-wall contouring surgery (chest-wall reconstructive surgery) is often the first surgical procedure in female-to-male (FtM) gender reassignment surgery (GRS). The main goal of this procedure is to create an aesthetically pleasing male-like chest contour. No universally accepted algorithm exists for detection of the appropriate surgical technique. Also, there is no tool for objective evaluation of the quality of life and satisfaction of these patients after the operation. METHODS: This study involves a single-center clinical trial assessing the patients who underwent subcutaneous mastectomy in FtM GRS between 2003 and 2019. The selection of patients was based on the new "simplified" algorithm consisting of 2 different surgical techniques: the semicircular and the double-incision with free nipple grafting. The selection was based on 3 criteria: breasts size, breast ptosis, and skin elasticity. The outcomes and complication rates were collected and analyzed. The patients' satisfaction and Quality of Life was assessed with a 5-point Likert scale questionnaire, specifically conceived for FtM patients. The aesthetic evaluation was performed using a 5-point Likert scale dealing with the 5 items featuring as the main goals of GRS. RESULTS: 184 mastectomies were performed in 92 FtM GRS patients. The overall reoperation rate was 11.9%. The patient survey revealed both a high satisfaction rate and a good aesthetic result (4.4/5). CONCLUSIONS: The proposed algorithm facilitates the selection of the most suitable technique for top surgery. The patient satisfaction rate evaluated by the proposed Health-Related Quality of Life questionnaire confirmed the outcomes of the use of the algorithm. Further studies to validate the proposed evaluating tools are needed.

Prolonged Low-Dose Methylprednisolone in Patients With Severe COVID-19 Pneumonia.

BACKGROUND: In hospitalized patients with coronavirus disease 2019 (COVID-19) pneumonia, progression to acute respiratory failure requiring invasive mechanical ventilation (MV) is associated with significant morbidity and mortality. Severe dysregulated systemic inflammation is the putative mechanism. We hypothesize that early prolonged methylprednisolone (MP) treatment could accelerate disease resolution, decreasing the need for intensive care unit (ICU) admission and mortality. METHODS: We conducted a multicenter observational study to explore the association between exposure to prolonged, low-dose MP treatment and need for ICU referral, intubation, or death within 28 days (composite primary end point) in patients with severe COVID-19 pneumonia admitted to Italian respiratory high-dependency units. Secondary outcomes were invasive MV-free days and changes in C-reactive protein (CRP) levels. RESULTS: Findings are reported as MP (n = 83) vs control (n = 90). The composite primary end point was met by 19 vs 40 (adjusted hazard ratio [aHR], 0.41; 95% CI, 0.24-0.72). Transfer to ICU and invasive MV were necessary in 15 vs 27 (P = .07) and 14 vs 26 (P = .10), respectively. By day 28, the MP group had fewer deaths (6 vs 21; aHR, 0.29; 95% CI, 0.12-0.73) and more days off invasive MV (24.0 ±â€…9.0 vs 17.5 ±â€…12.8; P = .001). Study treatment was associated with rapid improvement in PaO2:FiO2 and CRP levels. The complication rate was similar for the 2 groups (P = .84). CONCLUSION: In patients with severe COVID-19 pneumonia, early administration of prolonged MP treatment was associated with a significantly lower hazard of death (71%) and decreased ventilator dependence. Treatment was safe and did not impact viral clearance. A large randomized controlled trial (RECOVERY trial) has been performed that validates these findings. Clinical trial registration.

Age Dependent Modification of the Metabolic Profile of the Tibialis Anterior Muscle Fibers in C57BL/6J Mice.

Skeletal muscle aging is accompanied by mass reduction and functional decline, as a result of multiple factors, such as protein expression, morphology of organelles, metabolic equilibria, and neural communication. Skeletal muscles are formed by multiple fibers that express different Myosin Heavy Chains (MyHCs) and have different metabolic properties and different blood supply, with the purpose to adapt their contraction to the functional need. The fine interplay between the different fibers composing a muscle and its architectural organization determine its functional properties. Immunohistochemical and histochemical analyses of the skeletal muscle tissue, besides evidencing morphological characteristics, allow for the precise determination of protein expression and metabolic properties, providing essential information at the single-fiber level. Aiming to gain further knowledge on the influence of aging on skeletal muscles, we investigated the expression of the MyHCs, the Succinate Dehydrogenase (SDH) activity, and the presence of capillaries and Tubular Aggregates (TAs) in the tibialis anterior muscles of physiologically aging C57BL/6J mice aged 8 (adult), 18 (middle aged), and 24 months (old). We observed an increase of type-IIB fast-contracting fibers, an increase of the oxidative capacity of type-IIX and -IIA fibers, a general decrease of the capillarization, and the onset of TAs in type-IIB fibers. These data suggest that aging entails a selective modification of the muscle fiber profiles.
