SARS-CoV-2 transmission in the Lombardy Region: the increase of household contagion and its implication for containment measures

This study aimed at the identification of the settings linked to SARS-CoV-2 transmission through the analysis of clusters and small outbreaks detected by the Lombardy Region surveillance system during the second epidemic wave. Comparing the data before and after the introduction of restrictive measures (night curfew, partial closure of schools and businesses, smart working), we observed a significant decrease of infections in workplaces, social gatherings, coffee shops, restaurants, and sports centers; contagion in schools decreased from 9.8% to 3.4%, in hospitals environments and nursing homes from 5.2% to 2%; domestic infections increased instead from 72.8% to 92.7%. These results suggest that containment measures have been effective in controlling virus circulation in the community but not at the household level and might inform future interventions, including the establishment of structures (Covid Hotels) for the isolation infected people. At the same time, they raise awareness on the risk of transmission among family members and during households social gatherings. (www.actabiomedica.it)
Paediatric appendicitis during the COVID‐19 pandemic

The repercussions of the pandemic on patients without COVID‐19 have been well documented. Although there is evidence that adult patients present later with complicated appendicitis, the impact on the paediatric population is unknown. Therefore, the aim of this study was to assess the impact of the COVID‐19 pandemic on the presentation and management of paediatric appendicitis.
Advancements in Neuroimaging to Unravel Biological and Molecular Features of Brain Tumors

Simple Summary Advanced neuroimaging is gaining increasing relevance for the characterization and the molecular profiling of brain tumor tissue. On one hand, for some tumor types, the most widespread advanced techniques, investigating diffusion and perfusion features, have been proven clinically feasible and rather robust for diagnosis and prognosis stratification. In addition, 2-hydroxyglutarate spectroscopy, for the first time, offers the possibility to directly measure a crucial molecular marker. On the other hand, numerous innovative approaches have been explored for a refined evaluation of tumor microenvironments, particularly assessing microstructural and microvascular properties, and the potential applications of these techniques are vast and still to be fully explored. Abstract In recent years, the clinical assessment of primary brain tumors has been increasingly dependent on advanced magnetic resonance imaging (MRI) techniques in order to infer tumor pathophysiological characteristics, such as hemodynamics, metabolism, and microstructure. Quantitative radiomic data extracted from advanced MRI have risen as potential in vivo noninvasive biomarkers for predicting tumor grades and molecular subtypes, opening the era of “molecular imaging” and radiogenomics. This review presents the most relevant advancements in quantitative neuroimaging of advanced MRI techniques, by means of radiomics analysis, applied to primary brain tumors, including lower-grade glioma and glioblastoma, with a special focus on peculiar oncologic entities of current interest. Novel findings from diffusion MRI (dMRI), perfusion-weighted imaging (PWI), and MR spectroscopy (MRS) are hereby sifted in order to evaluate the role of quantitative imaging in neuro-oncology as a tool for predicting molecular profiles, stratifying prognosis, and characterizing tumor tissue microenvironments. Furthermore, innovative technological approaches are briefly addressed, including artificial intelligence contributions and ultra-high-field imaging new techniques. Lastly, after providing an overview of the advancements, we illustrate current clinical applications and future perspectives.
A prospective, population-based, surveillance (BOSU) study of uveal effusion syndrome in the UK

Purpose: To determine the incidence and demographic profile of uveal effusion syndrome (UES), and to describe the visual and anatomic outcome following deep sclerectomy or vortex vein decompression. Methods: The British Ophthalmological Surveillance Unit (BOSU) mails reporting cards monthly to 1149 senior UK ophthalmologists, who are requested to report incident cases of specified rare diseases. UES was included in the reporting system from October 2009 to October 2011. If UES was identified, ophthalmologists were mailed a questionnaire to collect anonymized clinical data at baseline, and 12 months after. Results: Over 2 years, 29 cases were reported. Two cases were duplicates and 12 failed to meet the eligibility criteria. Of the 15 eligible cases, age ranged from 11 to 91 years (mean 62) and nine were males (60%). Ten patients were hypermetropic; three had an axial length of 19.0 mm or less. Estimated annual incidence was 1.2 per 10 million population. Seven cases were managed nonsurgically, including observation (one case), topical steroids (two cases), systemic steroids (three cases), and cyclodiode laser (one case). Eight cases (11 eyes) underwent full-thickness sclerectomy; the elevated flap was retained in four. The sclera was noted to be thick and rigid during surgery in five cases. Median preoperative visual acuity was 6/18, changing slightly to 6/21.5 at final review, with three eyes showing complete anatomic response, five showing some improvement, and three failing to respond. Conclusions: UES is extremely rare. It occurs in a range of ages, but is most common in middle-aged, hypermetropic men. Visual acuity can be materially reduced. The most commonly used surgical treatment in the UK is deep sclerectomy.
Observation of an indirect pathway in the femtosecond study of alkyl nitrite photodissociation in the S1 state

The present work has addressed the question of the dissociation time of four alkyl nitrites upon photoexcitation in the S1 state (methyl nitrite, n‐ , and t‐butyl nitrites and i‐amyl nitrite). The time resolved Laser Induced Fluorescence technique has been used in the femtosecond regime under bulk conditions. The photodissociation has been initiated at 351 nm by 150 fs pump pulses, and has been probed using a two‐photon process at 467 nm by 200 fs pulses. The LIF signal has qualitatively the same shape for the four nitrites: it passes through a transient peak before reaching a plateau. The two‐photon process that induces the detected fluorescence is nonresonant for detection of the dissociation product NO through the A←X transition. Conversely, the two‐photon process is resonant or quasiresonant for detection of the excited nitrite molecule in the S1 level before it dissociates. This leads to an enhanced detection efficiency of the non‐dissociated excited molecule versus that of the NO fragment. A simple .
Drought Stress Impacts on Plants and Different Approaches to Alleviate Its Adverse Effects

Drought stress, being the inevitable factor that exists in various environments without recognizing borders and no clear warning thereby hampering plant biomass production, quality, and energy. It is the key important environmental stress that occurs due to temperature dynamics, light intensity, and low rainfall. Despite this, its cumulative, not obvious impact and multidimensional nature severely affects the plant morphological, physiological, biochemical and molecular attributes with adverse impact on photosynthetic capacity. Coping with water scarcity, plants evolve various complex resistance and adaptation mechanisms including physiological and biochemical responses, which differ with species level. The sophisticated adaptation mechanisms and regularity network that improves the water stress tolerance and adaptation in plants are briefly discussed. Growth pattern and structural dynamics, reduction in transpiration loss through altering stomatal conductance and distribution, leaf rolling, root to shoot ratio dynamics, root length increment, accumulation of compatible solutes, enhancement in transpiration efficiency, osmotic and hormonal regulation, and delayed senescence are the strategies that are adopted by plants under water deficit. Approaches for drought stress alleviations are breeding strategies, molecular and genomics perspectives with special emphasis on the omics technology alteration i.e., metabolomics, proteomics, genomics, transcriptomics, glyomics and phenomics that improve the stress tolerance in plants. For drought stress induction, seed priming, growth hormones, osmoprotectants, silicon (Si), selenium (Se) and potassium application are worth using under drought stress conditions in plants. In addition, drought adaptation through microbes, hydrogel, nanoparticles applications and metabolic engineering techniques that regulate the antioxidant enzymes activity for adaptation to drought stress in plants, enhancing plant tolerance through maintenance in cell homeostasis and ameliorates the adverse effects of water stress are of great potential in agriculture.
Assessment of Testicular Lhcgr mRNA Expression Correlated with Testis and Seminal Vesicle Activities in the Libyan jird (Meriones libycus, Rodentia: Muridae) during Breeding Season Compared with Nonbreeding Season

Simple Summary The breeding periods of desert rodents should be favorable to the survival of small young, conditioned by the availability of food that occurs in the Libyan jird biotope during the long photoperiod and the high temperatures. The Libyan jird (Meriones libycus) were caught in their natural biotope in the Saharan desert in Algeria and showed a seasonal cycle of the testis activity, characterized by the highest peak during spring (the breeding season) and the lowest activity was registered during autumn and winter (nonbreeding season). Lhcgr mRNA expression is increased in autumn and decreased in spring. This expression varied in an opposite manner to testicular and seminal vesicle structures. Abstract The Libyan jird (Meriones libycus, 1823) is a wild desert rodent that is a seasonal breeder species adapted to breed when the environmental conditions can satisfy the energy and hydrous requirements of pregnant and nursing females to ensure that births occur at the most favorable time of the year. We assessed gene expression of testicular luteinizing hormone receptor (Lhcgr) correlated to testis activity. The expression of Lhcgr was evaluated using quantitative Real Time-Polymerase Chain Reaction (qRT-PCR and the testis activity by a histological method in adult male Libyan jirds during the nonbreeding and breeding seasons. Our results showed that Lhcgr mRNA expression increased in autumn during the nonbreeding season and decreased in spring during the breeding season. This expression varied in contrast to testicular structure or function and plasma testosterone levels. These results help to elucidate this desert rodent’s seasonal sexual activity, which is correlated with central regulation.
Clinicopathologic Features of Peripheral T-Cell Lymphoma in Sub-Saharan Africa.

OBJECTIVES Peripheral T-cell lymphomas (PTCLs) are heterogeneous, clinically aggressive, and rare. Subtype distribution varies by geographic location; however, data from sub-Saharan Africa (SSA) are lacking. We sought to elucidate clinicopathologic features of PTCL in SSA. METHODS We reviewed PTCL consultation cases from three SSA countries. PTCL subtype was determined per 2017 World Health Organization classification. Cases with sufficient material were evaluated by polymerase chain reaction for human T-cell leukemia virus type 1 (HTLV-1) and T-cell receptor γ (TCRG) rearrangement. RESULTS Among 32 cases, median age was 45 years and male-to-female ratio was 1.7. Thirty (94%) of 32 cases required additional workup for subclassification. PTCL, not otherwise specified (PTCL-NOS) was the most common subtype (13/32, 41%), followed by PTCL with T-follicular helper phenotype (6/32, 19%) and systemic anaplastic large cell lymphoma (6/32, 19%). Four (16%) of 25 cases were Epstein-Barr virus positive (EBV+) (2/2 extranodal natural killer/T-cell lymphoma, 1/13 PTCL-NOS, and 1/4 angioimmunoblastic T-cell lymphoma with EBV+ immunoblasts). Two (15%) of 13 patients with PTCL-NOS were human immunodeficiency virus positive. No cases with evaluable DNA (0/15) were HTLV-1 positive, and 9 of 10 showed clonal TCRG rearrangements. CONCLUSIONS In comparison to Western studies, PTCLs from SSA show similar subtype distribution and male predominance but a younger age at diagnosis. Appropriate diagnosis of PTCL requires extensive ancillary testing not readily available in low-income countries, including much of SSA.
Ten-Year Survivorship, Patient-Reported Outcome Measures, and Patient Acceptable Symptom State After Over-the-Top Hamstring Anterior Cruciate Ligament Reconstruction With a Lateral Extra-articular Reconstruction: Analysis of 267 Consecutive Cases

Background: Long-term patient-reported outcome measures (PROMs) and predictors of success or failure after anterior cruciate ligament (ACL) reconstruction are not fully understood, especially when combined with a lateral extra-articular reconstruction. Purpose: To assess the long-term PROMs, revision rate, and predictors of success or failure after ACL reconstructions using an over-the-top surgical technique with single-bundle hamstring tendon autografts and a lateral extra-articular reconstruction. Study Design: Case series; Level of evidence, 4. Methods: The study cohort consisted of 267 consecutive patients (mean age, 30.7 years) who underwent ACL reconstruction with an over-the-top surgical technique with single-bundle hamstring tendon autografts and a lateral extra-articular augmentation between November 2007 and May 2009. The number of subsequent ACL revisions and reoperations were recorded. Subjective clinical status was assessed with PROMs—specifically, the Knee injury and Osteoarthritis Outcome Score (KOOS), Lysholm, Tegner, and visual analog scale for pain—at a minimum follow-up of 10 years. Results: Overall, 3% of patients underwent ACL revision, with a 10-year survival rate of 96.3%. High sport activity (hazard ratio, 6.9; P = .285) and concomitant meniscal lesion (hazard ratio, 2.6; P = .0487) were predictors of ACL revision or new meniscectomy. The mean ± SD Lysholm score was 94.1 ± 10.8, while that for the visual analog scale for pain was 0.2 ± 0.9 at rest and 2.1 ± 2.6 during activity. KOOS subscale scores were as follows: 95.7 ± 8.1 for Pain, 92.5 ± 10.5 for Symptoms, 98.4 ± 7.4 for Activities of Daily Living, 90.7 ± 17.2 for Sport, and 91.2 ± 17.1 for Quality of Life; respectively, 88%, 99%, 81%, 89%, and 91% of patients achieved the Patient Acceptable Symptom State. Female sex and chondropathy with Outerbridge grade ≥2 were predictors of worse KOOS subscales. Overall, 82% of patients returned to sport, and 57% were still participating at the 10-year evaluation. Conclusion: ACL reconstruction with an over-the-top surgical technique with single-bundle hamstring autografts and a lateral extra-articular reconstruction provided satisfactory results in terms of function, symptoms, sports, and quality of life in 80% to 90% of patients after 10 years. Long-term survivorship was 96%. Sport participation declined from 82% postoperatively to 57% at long-term follow-up. A concomitant medial meniscal lesion was a predictor of higher risk of ACL failure or new meniscal lesion, while advanced chondropathy and female sex were predictors of higher pain, lower function, and poor quality of life scores.
Multifactorial Rare Diseases: Can Uncertainty Analysis Bring Added Value to the Search for Risk Factors and Etiopathogenesis?

Uncertainty analysis is the process of identifying limitations in knowledge and evaluating their implications for scientific conclusions. Uncertainty analysis is a stable component of risk assessment and is increasingly used in decision making on complex health issues. Uncertainties should be identified in a structured way and prioritized according to their likely impact on the outcome of scientific conclusions. Uncertainty is inherent to the rare diseases (RD) area, where research and healthcare have to cope with knowledge gaps due to the rarity of the conditions; yet a systematic approach toward uncertainties is not usually undertaken. The uncertainty issue is particularly relevant to multifactorial RD, whose etiopathogenesis involves environmental factors and genetic predisposition. Three case studies are presented: the newly recognized acute multisystem inflammatory syndrome in children and adolescents associated with SARS-CoV-2 infection; the assessment of risk factors for neural tube defects; and the genotype–phenotype correlation in familial Mediterranean fever. Each case study proposes the initial identification of the main epistemic and sampling uncertainties and their impacts. Uncertainty analysis in RD may present aspects similar to those encountered when conducting risk assessment in data-poor scenarios; therefore, approaches such as expert knowledge elicitation may be considered. The RD community has a main strength in managing uncertainty, as it proactively develops stakeholder involvement, data sharing and open science. The open science approaches can be profitably integrated by structured uncertainty analysis, especially when dealing with multifactorial RD involving environmental and genetic risk factors.
Parasacral Transcutaneous Electrical Nerve Stimulation for the Treatment of Children and Adolescents with Bladder and Bowel Dysfunction: A Randomized Clinical Trial

Purpose: Parasacral transcutaneous electrical nerve stimulation has been used to manage lower urinary tract symptoms refractory to standard urotherapy. Nevertheless, its actual effectiveness in treatment of bladder and bowel dysfunction remains to be established. We sought to evaluate the effectiveness of parasacral transcutaneous electrical nerve stimulation in the treatment of children with bladder and bowel dysfunction. Materials and Methods: This was a randomized clinical trial conducted with children and adolescents of 5–17 years of age diagnosed with bladder and bowel dysfunction. Patients with neurological or anatomical abnormalities of urinary or digestive tracts, those unable to attend treatment sessions 3 times a week, individuals with diabetes mellitus or diabetes insipidus and those using anticholinergic drugs or laxatives were excluded from the study. The sample was divided into 2 groups: a control group submitted to standard urotherapy plus sham electrotherapy applied to the scapular region and a treatment group submitted to urotherapy plus parasacral transcutaneous electrical nerve stimulation. All the patients were submitted to 3, 20-minute electrotherapy (parasacral transcutaneous electrical nerve stimulation or sham) sessions/week for a total of 20 sessions. Results: Forty patients were evaluated, 20 in the control group and 20 in the treatment group. Mean age (±standard deviation) was 8.4±2.8 years and 52.5% were male. In 15 patients (37.5%), rectal diameter was ≥3 cm. Lower urinary tract symptoms improved in both groups following treatment, with no statistically significant differences in Dysfunctional Voiding Scoring System score, lower urinary tract symptoms or uroflowmetry patterns between the groups. Intragroup evaluation showed a significant improvement in enuresis in the treatment group. There was a significant improvement in functional constipation post-intervention in treatment group compared to control group (70% vs 20%, p=0.004). Conclusions: Parasacral transcutaneous electrical nerve stimulation is effective for treatment of bladder and bowel dysfunction in children and adolescents, particularly insofar as functional constipation is concerned.
Transcutaneous monitoring of diaphragm activity as a measure of work of breathing in preterm infants

Monitoring work of breathing (WOB) is important to assess the pulmonary condition and adjust respiratory support in preterm infants. Conventional WOB measurement (esophageal pressure, tidal volume) is invasive and we hypothesized that monitoring diaphragm activity could be a noninvasive alternative to estimate WOB. The objective was to determine the correlation between conventional WOB measures and diaphragm activity, in preterm infants.
Students’ views and experiences of the training and use of phonetic transcription in speech and language therapy – the Irish perspective

ABSTRACT Phonetic transcription is an essential skill for a practising speech and language therapist (SLT) required during the assessment, diagnosis and management of clients with speech difficulties. It is vital that appropriate training is received by student SLTs to ensure that they carry out phonetic transcription accurately and reliably once out in the workplace. This study investigates the views and experiences of final year SLT students regarding the training in phonetic transcription they received in university, with the aim to identify what poses difficulties for them and what could be done to enhance their learning. Responses from 40 participants representing one cohort of SLT students, graduates of a particular year, were collected using an online questionnaire. The majority of the respondents consider phonetic transcription an important professional skill and plan on maintaining it after graduating. Learning phonetic transcription was easy/quite easy for 57% of the respondents; however, the confidence in transcription skills was rather low: 70% of them reported not being confident and fully equipped to enter the workforce with their transcription skills. The main difficulties were associated with narrow (impressionistic) transcription and transcription of disordered speech. 58% of the respondents found the teaching environment suitable; however, a recurring theme is the need for small-group tutorials during which the lecturers could provide feedback to individual students more efficiently. Participants’ responses suggest that more clinically relevant transcription practice of disordered speech, the opportunity to refresh and apply phonetic transcription skills throughout the four-year curriculum and smaller group teaching would benefit their learning and enhance their confidence using transcription on placements and in the workforce.
The effect of job stress management training on observance of professional ethics by nurses

Abstract The present study was conducted to investigate the effect of job stress management training on observance of professional ethics by nurses. This quasi-experimental study was performed on 50 clinical nurses in Shiraz, Iran. Data collection tools included a questionnaire. The research intervention consisted of six two-hour sessions of stress management training. SPSS 21 were used to analyze the data. Data analysis showed that before intervention, the level of professional ethics of 64% of nurses was relatively good, but after intervention, the level of professional ethics of the majority of nurses (94%) was at the desired level. The results showed that the levels of professional ethics after job stress management training has increased significantly compared to before. The results showed that stress management training has led to improving the level of professional ethics of nurses.
