Background: The COVID-19 pandemic had an important psychological impact on children and their families. This study aims to explore paediatric health services users' perceptions of quality of care (QOC) and COVID-19-related fears, and their evolution over time in relation to COVID-19 pandemic., Methods: In a multicentre cross-sectional study involving 11 public hospitals providing paediatric care across the Italian territory, we collected data from services users through a validated questionnaire. We analysed four indicators-(1) QOC perceived in relation to COVID-19; (2) overall QOC perceived; (3) fear of accessing health services due to COVID-19; (4) fear of contracting COVID-19 in hospital-and calculated Spearman's correlation indexes (ρ) with the number of COVID-19 new cases over time. Subgroup analyses were conducted by macroregions and single facility., Results: Data from 956 services users were analysed. QOC indicators were stable over time at values close to the maximum (range 77-100 and median 100 for COVID-19 QOC, range 74-98 and median 80 for overall QOC), and no correlations were found with the COVID-19 new cases (ρ=-0.073 and -0.016, respectively). Fear of accessing care and fear of contracting the infection varied over time in between 0%-52% and 0%-53%, respectively, but did not correlate directly with number of COVID-19 new cases (ρ=0.101, 0.107 and 0.233, 0.046, respectively). At subgroup analyses, significantly higher frequencies of fear (p values <0.05) and lower QOC (p values <0.001) were reported in South Italy, and three facilities showed moderate correlation between these indicators., Conclusions: COVID-19-related fears and perceived QOC may be mediated by more complex cultural and facility/regional-level factors, than simply by epidemic peaks. Subgroup analyses can help unpack major differences within the same country., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: Despite quadriceps weakness in individuals after quadriceps tendon anterior cruciate ligament reconstruction (QT-ACLR), and its association with knee joint mechanics, no studies have addressed gait mechanics in both partial-thickness (PT-Q) and full-thickness (FT-Q) options for QT-ACLR., Objective: To assess gait mechanics across a QT-ACLR cohort. We hypothesized that QT-ACLR would show changes in knee joint mechanics compared to control participants (CON) and nonoperated limbs. Additionally, we hypothesized that FT-Q operated limbs would show greater changes compared to PT-Q and CON., Design: Retrospective cohort study., Setting: University-affiliated sports medicine institute., Participants: Sixteen patients who underwent QT-ACLR (7 FT-Q: Age (years) = 28.6 ± 7.3, post-op (months) = 23.5 ± 10.7, 9 PT-Q: Age = 25.2 ± 4.3, post-op = 24.4 ± 11.7) were recruited and compared to 11 CON (age = 23.4 ± 4.8)., Intervention: Participants underwent gait testing with force plate integrated motion capture., Main Outcome Measures: Mixed repeated-measures analyses of covariance, adjusted for gait speed, were used to determine significant main effects or interactions in peak knee flexion angle, sagittal knee range of motion, peak internal knee extension moment (KEM), and peak internal knee flexion moment., Results: When measured an average of 2 years after surgery, no main effect for limb or limb by depth interaction were detected. A significant effect by group was observed for peak KEM (p = .03, η 2  = .27) and peak knee flexion angle (p = .04, η 2  = .24) in the loading response phase. FT-Q (p = .02) and PT-Q (p = .03) showed lower KEM compared to the CON group in both limbs. The FT-Q group showed lower peak knee flexion angle compared to the CON group (p = .01)., Conclusions: Knee joint symmetry may be recovered 2 years following QT-ACLR, but lower KEM compared to CON for both graft options and lower peak knee flexion angle than CON for the FT-Q group may indicate a need for further investigation in QT-ACLR., (© 2024 The Author(s).

Aims: i) to compare 30-s sit-to-stand (STS) test repetitions and power between older adults with and without Parkinson's disease (PD) and ii) to evaluate the relationship of STS repetitions and power with functional measures in older people with PD., Methods: STS repetitions and power (Alcazar's equation) during the 30-s STS test were assessed in forty-six age- and sex-matched older adults with and without PD. Functional measures included habitual (HGS) and maximum gait speed (MGS), timed-up-and-go (TUG) test and the Mini-Balance Evaluation System Test (Mini-BEST). PD-specific tests were as follows: the motor subscale of the Unified Parkinson's Disease Rating Scale (UPDRS-III), quality of life [Parkinson's Disease Questionnaire (PDQ-39)], perceived freezing of gait (FOG questionnaire), and fear of falling [Falls Efficacy Scale (FES)]. T scores, repeated measures ANOVA and linear regression analyses were used., Results: T scores for older adults with PD were - 2.7 ± 4.5 for STS repetitions, -5.2 ± 4.2 for absolute STS power, and - 3.1 ± 4.6 for relative STS power compared to older adults without PD. T scores for absolute STS power were lower than T scores for STS repetitions (p < 0.001) and relative STS power (p < 0.001). Both absolute and relative STS power and STS repetitions showed similar correlations with functional measures (r = 0.44 to 0.59; both p < 0.05). Relative STS power (r = -0.55; p < 0.05) and STS repetitions (r = -0.47 to -0.55; p < 0.05) but not absolute STS power were correlated to PD-specific tests., Conclusions: STS repetitions and power values estimated through the 30-s STS test were lower in older people with PD than without PD. Overall, STS power measures were similarly associated with functional performance as STS repetitions, indicating these power equations can be implemented when assessing lower extremity function in older people with PD., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Objectives: There is little experience in implementing the WHO Standards for improving the quality of care (QOC) for children. We describe the use of 75 WHO-Standard based Quality Measures to assess paediatric QOC, using health workers (HWs) as data sources., Design: Cross-sectional study., Setting: 12 Italian hospitals., Participants: The minimum target of 75% of HWs was reached in all facilities; answers from 598 HWs were analysed., Primary and Secondary Outcome Measures: 75 prioritised WHO Quality Measures were collected using a validated, and Italian-language questionnaire exploring views of HWs providing care to children. A QOC index was also calculated based on the assessed Quality Measures., Results: In both the domain of resources and work organisation, most Quality Measures showed a high overall frequency of reported 'need for improvement', with high variability across hospitals. Key needs for improvement included: availability of clear and complete protocols (eg, on paediatric emergencies: 44.6%; range 10.6%-92.6%); clear hospitalisation criteria for diarrhoea (50.5%; range 30.3%-71.7%); number of hand-washing stations (13.2%; range 3.4%-37.0%); equipped working rooms with computers for HWs (66.1%; range: 32.1%-97.0%); training (eg, on pain management: 43.5%; range 17.9%-76.7%), periodic discussion of clinical cases (43.5%; range 8.1%-83.7%) audits (48.8%; range 29.7%-76.7%); and all indicators related to system to improve QOC. Factors significantly associated with a lower QOC Index included HWs working in facilities in Southern Italy (p=0.001) and absence of a paediatric emergency department (p=0.011)., Conclusions: The use of the 75 prioritised Quality Measures, specific to HWs provide valuable data on paediatric QOC, which can be used to drive a quality improvement process., Competing Interests: Competing interests: No, there are no competing interests., (© Author(s) (or their employer(s)) 2024.

Objectives: There is little experience in the use of the WHO Standards for improving the quality of care (QOC) for children at the facility level. We describe the use of 75 WHO Standard based Quality Measures to assess paediatric QOC, using service users as a source of data, in Italy., Study Design: In a cross-sectional study including 12 hospitals, parents/caregivers of admitted children completed a validated questionnaire including 75 Quality Measures: 40 pertinent to the domain of experience of care; 25 to physical/structural resources; 10 to COVID-19 reorganisational changes. Univariate and multivariate analyses were conducted., Results: Answers from 1482 service users were analysed. Physical resources was the domain with the higher frequency of reported gaps in QOC, with key gaps (higher rates of responders reporting need for improvement and low variability across centres) being: (1) quality of meals (48.1%; range across facilities: 35.3%-61.7%); (2) presence of cooking areas (50.9%; range: 34.6%-70.0%); (3) spaces for family/friends (51.3%; range: 31.8%-77.4%). For experience of care , the most critical gap was the information on the rights of the child (76.6%; range: 59.9%-90.4%), with most other Quality Measures showing an overall frequency of reported need for improvement ranging between 5% and 35%. For reorganisational changes due to COVID-19 an improvement was felt necessary by <25% of responders in all Quality Measures, with low variability across centres. At the multivariate analyses, factors significantly associated with the QOC Index largely varied by QOC domain., Conclusions: The use of the 75 prioritised Quality Measures, specific to service users' perspective, enabled the identification of both general and facility-specific gaps in QOC. Based on these findings, quality improvement initiatives shall focus on a core list of selected Quality Measures common to all facilities, plus on an additional list of Quality Measures as more relevant in each facility., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Abstract: Calaway, C, Mishra, S, Parrino, R, Martinez, KJ, Mann, JB, and Signorile, JF. Velocity-based training affects the load-velocity relationship in leg press and chest press for older persons. J Strength Cond Res 38(6): 1136-1143, 2024-This study examined the impact of 3 months of velocity-based training (VBT) on chest press (CP) and leg press (LP) maximal strength (1 repetition maximum [1RM]), peak power (PP), and percentage load where PP was achieved (%1RMPP) in older adults. Twenty-nine subjects were assigned to either a velocity-deficit (VD) group or a force-deficit (FD) group for each exercise depending on their load-velocity (LV) curves. Changes in load were determined by the ability to maintain either 90% (VD) or 70% (FD) of their PP during training. Subjects' powers were tested before and after the training intervention at loads between 40 and 80%1RM. Separate 2 (group) × 2 (time) ANOVA was used to examine changes in each variable by group for each exercise. Wilcoxon signed-rank tests were used to determine whether significant changes in %1RMPP for each exercise and group. For chest press 1 repetition maximum, there were no significant main effects or interaction. Significant main effects for time were observed for leg press 1 repetition maximum ( p < 0 .001, η2 = 0.547) and chest press peak power ( p = 0.009, η2 = 0.243). For LPPP, there were no significant main effects or interactions. For %1RMPP, CP median scores revealed no significant changes for either group. Significant declines in %1RMPP were observed for leg press velocity-deficit and leg press force-deficit ( p < 0.03) groups. Velocity-based training was effective at improving 1RM, PP, and shifting %1RMPP in the LP groups. These results have implications for targeting power improvements at specific areas of the LV curve. Health care providers and trainers should consider these findings when constructing exercise programs to counter age-related declines in older adults., (Copyright © 2024 National Strength and Conditioning Association.)

Acute bacterial skin and skin-structure infections (ABSSSI) are a significant cause of morbidity in pediatric patients, requiring timely and effective treatment. Dalbavancin, a long-acting lipoglycopeptide antibiotic recently approved for pediatric use, offers advantages such as excellent bactericidal activity against Gram-positive bacteria (including multidrug-resistant pathogens) and high tissue penetration. We present a case series of pediatric patients with ABSSSI treated with dalbavancin. Five cases were described demonstrating the efficacy of dalbavancin in different clinical scenarios. Patients with complex skin conditions, including cellulitis and deep abscesses, benefited from dalbavancin therapy, achieving significant clinical improvement. Notably, dalbavancin facilitated early discharge, improving quality of life and reducing healthcare costs. These cases highlight the potential of dalbavancin as a valuable treatment option for ABSSSI in pediatric patients, particularly in settings where conventional therapies fail to achieve optimal clinical outcomes or prolonged hospitalization is not feasible. Further research is needed to clarify its role and optimize its use in pediatric patients with ABSSSI., Competing Interests: Conflict of interest: The authors declare no conflict of interest.

Purpose: To determine the changes in retinal microvascular density after a 24-week high-speed circuit resistance training program (HSCT) in healthy older adults., Methods: Thirty healthy older adults were recruited and randomly assigned to either a training group (HSCT) or a non-training (CON) group. Fifteen subjects (age 73.3 ± 7.76 yrs) in the HSCT group exercised three times per week on non-consecutive days for 24 weeks. Fifteen subjects in the CON group (age 72.2 ± 6.04 yrs) did not have formal physical training. Both eyes of each subject were imaged using optical coherence tomography angiography (OCTA) at baseline and at the 24-week follow-up. The vessel densities of the retinal vascular network (RVN), superficial vascular plexus (SVP), and deep vascular plexus (DVP) were measured., Results: There were no demographic differences between the study groups. There were significant decreases in the retinal vessel densities of RVN, SVP and DVP in the HSCT group (P < 0.05). However, there were no significant changes in all three vascular measurements in the CON group (P > 0.05), although the changes showed a decreasing trend. The decreased vessel densities were doubled in the HSCT group in comparison to the CON group. However, the differences between groups did not reach a significant level (P > 0.05)., Conclusions: This is the first study to reveal the decreased retinal vessel densities as a possible imaging marker for the beneficial effects of the 24-week HSCT program in older adults., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Background: Patterns of coordinated variations of gray matter (GM) morphology across individuals are promising indicators of disease. However, it remains unclear if they can help characterize first-episode psychosis (FEP) and symptoms' severity., Methods: Sixty-seven FEP and 67 matched healthy controls (HC) were assessed with structural MRI to evaluate the existence of distributed GM structural covariance patterns associated to brain areas belonging to salience network. Voxel-based morphometry (VBM) and structural covariance differences, investigated with salience network seed-based Partial Least Square, were applied to explore differences between groups. GM density associations with Raven's intelligent quotient (IQ) and Positive and Negative Syndrome Scale (PANSS) scores were investigated., Results: Univariate VBM results gave trend without significant GM differences across groups. GM and IQ correlated positively in both groups: in FEP, mostly in hippocampus, insula, and fronto-temporal structures, while in HC mostly in amygdala, thalamus and fronto-temporal regions. GM and PANSS scores correlated negatively in FEP, with widespread clusters located in limbic regions. Multivariate analysis showed strong and opposite structural GM covariance with salience network for FEP and HC. Moreover, structural covariance of the salience network in FEP correlated negatively with severity of clinical symptoms., Conclusion: Our study provides evidence supporting the insular dysfunction model of psychosis. Reduced structural GM covariance of the salience network, with its association to symptom's severity, appears a promising morphometry feature for FEP detection., (Copyright © 2021 Elsevier Ltd.

BackgroundVery few studies describe factors associated with COVID-19 diagnosis in children.AimWe here describe characteristics and risk factors for COVID-19 diagnosis in children tested in 20 paediatric centres across Italy.MethodsWe included cases aged 0-18 years tested between 23 February and 24 May 2020. Our primary analysis focused on children tested because of symptoms/signs suggestive of COVID-19.ResultsAmong 2,494 children tested, 2,148 (86.1%) had symptoms suggestive of COVID-19. Clinical presentation of confirmed COVID-19 cases included besides fever (82.4%) and respiratory signs or symptoms (60.4%) also gastrointestinal (18.2%), neurological (18.9%), cutaneous (3.8%) and other unspecific influenza-like presentations (17.8%). In multivariate analysis, factors significantly associated with SARS-CoV-2 positivity were: exposure history (adjusted odds ratio (AOR): 39.83; 95% confidence interval (CI): 17.52-90.55; p < 0.0001), cardiac disease (AOR: 3.10; 95% CI: 1.19-5.02; p < 0.0001), fever (AOR: 3.05%; 95% CI: 1.67-5.58; p = 0.0003) and anosmia/ageusia (AOR: 4.08; 95% CI: 1.69-9.84; p = 0.002). Among 190 (7.6%) children positive for SARS-CoV-2, only four (2.1%) required respiratory support and two (1.1%) were admitted to intensive care; all recovered.ConclusionRecommendations for SARS-CoV-2 testing in children should consider the evidence of broader clinical features. Exposure history, fever and anosmia/ageusia are strong risk factors in children for positive SARS-CoV-2 testing, while other symptoms did not help discriminate positive from negative individuals. This study confirms that COVID-19 was a mild disease in the general paediatric population in Italy. Further studies are needed to understand risk, clinical spectrum and outcomes of COVID-19 in children with pre-existing conditions.

Gender is associated with several features of psychotic disorders, including age of illness onset, symptomatology, a higher prevalence of history of childhood sexual abuse (CSA) and needs for care. Childhood sexual abuse is associated with adverse mental health consequences but as there is a gender difference in stress reactivity, there may be a differential impact of CSA on psychopathology, age of psychosis onset and needs for care in First Episode Psychosis (FEP) patients. We hypothesized that a history of abuse would be associated with lowering of age of onset, increased symptomatology and more unmet needs in women but not men. A total of 444 FEP patients have been recruited within the context of the GET UP trial. Symptomatology has been assessed using the PANSS scale, needs for care with the CAN scale and childhood abuse with the CECA-Q scale. Childhood sexual abuse was more frequent among female patients [22.6% in women vs 11.6% in men (OR = 0.45, p < 0.01)], whereas there was no gender difference in the prevalence of childhood physical abuse (29.0% in women vs 31.7% in men). Childhood abuse was associated with higher levels of negative symptoms in both men and women, with a reduced age of onset in women only and little increase in needs for care in both men and women. Our results seem to suggest that childhood sexual abuse in female FEP patients may be linked to a more severe form of psychosis whose presentation is characterized by earlier age of onset and higher levels of negative symptoms and we can also speculate that gender-specific protective factors in women, but not in men, may be outweighed by the consequences of childhood abuse., (Copyright © 2019 Elsevier B.V.

Children with intellectual disability frequently undergo needle-related procedures for diagnosis or treatment. Nevertheless, only a few studies deal with pain and distress management during the procedure in this population of children. This study aimed to investigate the number of anxiety and pain management techniques performed during needle procedure in children with intellectual disability (cases) compared to a population of children without intellectual disability (controls). This multicenter cohort study was performed from July 2016 to January 2018 in the pediatric ward of four urban hospitals in Italy. Eligible subjects were children with and without intellectual disability, from 4 to 17 years old, who needed venipuncture or intravenous cannulation for diagnosis or treatment. Use of topical anesthesia, distraction techniques, and physical or verbal comfort during procedures were recorded. Pain and anxiety scores were also recorded. Forty-seven cases and 94 controls were recruited. Three pain- and anxiety-relieving techniques were performed during the procedure in 12 (25%) cases and in 10 controls (11%); two techniques were performed in 23 (50%) cases and in 26 (28%) controls; 12 (25%) cases and 52 (55%) controls received only one.Conclusion: In this series, children with intellectual disability received significantly more relieving techniques, but experienced more pain and anxiety when compared to children without intellectual disability. What is Known: • Children with intellectual disability experience more episodes of pain than cognitively healthy ones, and almost 10% of these episodes are due to medical procedures. What is New: • Children with intellectual disability despite receiving more relieving techniques during a needle-related procedure experienced more pain and anxiety when compared to healthy children.

Puberty is regulated by the endocrine system. Disruption of that system by exposure to environmental hormone-mimicking substances (i.e. endocrine disruptors) may, therefore, affect this development profoundly. There has been a great secular trend in the earlier timing of puberty such as both puberty onset and menarche age. This is apparently caused by environmental factors such as improved socioeconomic status, better healthcare and improved nutrition. However, part of the phenomenon could be associated with exposure to endocrine disruptors that have intrinsic estrogen activity or increase endogenous sex hormone levels. These estrogen pollutants tend to degrade slowly in the environment, to bioaccumulate in the food chain and to have long half-lives in humans. Because most of environmental chemicals, called estrogen disruptors or xenoestrogens, are toxic and estrogen/antiandrogen active, they can disregulate hypothalamic-pituitary-gonadal axis potentially inducing reproductive disorders. There are several case reports of accidental exposure to estrogenic compounds in cosmetic products, food and pharmaceuticals. The outbreak of epidemics of premature thelarche in some geographical areas has also been suggested to be linked to exposure to estrogen disrupters such as dioxins, furans and organohalogens. We review data on adverse health and reproductive outcomes have been attributed to estrogen disruptors in laboratory animals and in wildlife as well as in humans, specially focusing on the puberty timing.

Objective: To examine the effect of long-term administration of GnRH agonists (GnRHa) on PRL secretion in children affected by central precocious puberty (CPP) and growth hormone deficiency (GHD)., Design: Prospective analysis of blood sampling before, during, and after GnRHa treatments., Setting: Pediatric endocrine center., Patient(s): One hundred nineteen and 93 children with a diagnosis of CPP and GHD, respectively., Intervention(s): Monthly depot injections of GnRHa drugs (leuprorelin acetate 3.75 mg [LA] and triptorelin 3.75 mg [TR]) administered to CPP and GHD patients for 40 and 24 months, respectively., Main Outcome Measure(s): Serum PRL levels at baseline and after 6, 12, 18, 24, 30, 36, and 40 months of treatment with GnRHa were compared between CPP and GHD groups. PRL levels at 6 and 12 months after GnRHa withdrawal were also examined., Result(s): Although serum PRL levels tended to be higher in TR- than in LA-treated patients, no significant difference in circulating PRL in basal condition and during GnRHa treatment was detected between the CPP and GHD groups. However, five children (3.8%) developed hyperprolactinemia during TR treatment., Conclusion(s): Although there are no general concerns about GnRHa treatment safety, careful PRL monitoring is required in GnRHa-treated children.

Background: To evaluate the prevalence of headache in primary health care for children (child neuropsychiatry and pediatric primary care), detecting possible differences among areas, showing the number of patients with headache with a clinical significance that had not been communicated to a physician and studying the clinical features of cases., Methods: A questionnaire is administered to all consecutive patients of 3 child neuropsychiatrists of a primary health care unit during a period of 20 days and of 2 family pediatricians during a period of 10 days. Data are collected on 259 children, between 5 and 14 years., Results: 17.76% of examined children have recurrent headache. The percentage is significantly different (p < 0.05) in neuropsychiatry (22.78%) and pediatrics (9.90%). 63.04% of parents with children affected by headache have never reported the disease to a physician and 28.26% of affected children should follow a preventive therapy, but do not. Among all children, 6.56% have migraine and 8.49% have a tension-type headache, according to ICD-10 criteria., Conclusions: The higher frequency of headache in child neuropsychiatric primary care is probably due to a comorbidity with psychiatric diseases. The high number of non-reported cases of headache is in agreement with data reported in the literature about adults and suggests that it is important to ask standard questions about headache in the course of the anamnesis in all primary health care for children.
