RESUMO
OBJECTIVES: To study prevalence of infection in essential workers of Madrid City Council by occupation, related characteristics, use of protective devices, risk perception, and main concerns about COVID-19 during lockdown. METHODS: A total of 30 231 workers were PCR tested for SARS-CoV-2 infection. Information was collected on COVID-19-related symptoms, risk factors, preventive equipment, and risk perception. The crude prevalence was calculated for infection, use of protective devices, perceived risk and main concerns. Additionally, adjusted prevalence and prevalence ratios (PR) were estimated for these variables using logistic regression models with age, gender, occupation, epidemiological week and laboratory as confounding factors. RESULTS: Overall prevalence of infection was 3.2% (95% CI 3.0% to 3.4%), being higher among policemen (4.4%) and bus drivers (4.2%), but lower among emergency healthcare personnel, firefighters, food market workers and burial services (<2%). Lower excess risk was observed in workers reporting occupational contact with COVID-19 cases only (PR=1.42; 95% CI 1.18 to 1.71) compared with household exposure only (PR=2.75; 95% CI 2.32 to 3.25). Infection was more frequent in symptomatic workers (PR=1.28; 95% CI 1.11 to 1.48), although 42% of detected infections were asymptomatic. Use of facial masks (78.7%) and disinfectants (86.3%) was common and associated with lower infection prevalence (PRmasks=0.68; 95% CI 0.58 to 0.79; PRdisinfectants=0.75; 95% CI 0.61 to 0.91). Over 50% of workers felt being at high risk of infection and worried about infecting others, yet only 2% considered quitting their work. CONCLUSIONS: This surveillance system allowed for detecting and isolating SARS-CoV-2 cases among essential workers, identifying characteristics related to infection and use of protective devices, and revealing specific needs for work-safety information and psychological support.

Initially identified in DNA damage repair, ATM-interactor (ATMIN) further functions as a transcriptional regulator of lung morphogenesis. Here we analyse three mouse mutants, Atmin(gpg6/gpg6), Atmin(H210Q/H210Q) and Dynll1(GT/GT), revealing how ATMIN and its transcriptional target dynein light chain LC8-type 1 (DYNLL1) are required for normal lung morphogenesis and ciliogenesis. Expression screening of ciliogenic genes confirmed Dynll1 to be controlled by ATMIN and further revealed moderately altered expression of known intraflagellar transport (IFT) protein-encoding loci in Atmin mutant embryos. Significantly, Dynll1(GT/GT) embryonic cilia exhibited shortening and bulging, highly similar to the characterised retrograde IFT phenotype of Dync2h1. Depletion of ATMIN or DYNLL1 in cultured cells recapitulated the in vivo ciliogenesis phenotypes and expression of DYNLL1 or the related DYNLL2 rescued the effects of loss of ATMIN, demonstrating that ATMIN primarily promotes ciliogenesis by regulating Dynll1 expression. Furthermore, DYNLL1 as well as DYNLL2 localised to cilia in puncta, consistent with IFT particles, and physically interacted with WDR34, a mammalian homologue of the Chlamydomonas cytoplasmic dynein 2 intermediate chain that also localised to the cilium. This study extends the established Atmin-Dynll1 relationship into a developmental and a ciliary context, uncovering a novel series of interactions between DYNLL1, WDR34 and ATMIN. This identifies potential novel components of cytoplasmic dynein 2 and furthermore provides fresh insights into the molecular pathogenesis of human skeletal ciliopathies.

OBJECTIVE: To study the influence of a short programme of stretching exercises on anxiety levels of workers in a Spanish logistic company. METHOD: A controlled clinical trial was carried out by means of an inter-subject design of random homogeneous blocks. Participants were assigned to the experimental group (n=67), treated with a programme of stretching exercises of 10-minute duration after working hours for a period of 3 months, or to the untreated control group (n=67). The primary result variable was anxiety, and the secondary variables were burnout syndrome, quality of life and flexibility. An analysis of covariance (ANCOVA) by intention to treat was performed on each of the result variables by controlling the baseline scores, the age and the practice of introjective activities outside the program, with the size effect calculated by means of the partial eta-squared value (η(2)). RESULTS: The results of the ANCOVA showed a moderate effect of the stretching exercise programme on the levels of anxiety (η(2)=0,06; P=.004). Other effects found were substantial for flexibility (η(2)=0,13; P<.001); moderately high for bodily pain (η(2)=0,08; P=.001), and moderate for vitality (η(2)=0,05; P=.016); mental health (η(2)=0,05; P=.017); general health (η(2)=0,04; P=.028) and exhaustion (η(2)=0,04; P=.025). CONCLUSIONS: The implementation of a short programme of stretching exercises in the work place was effective for reducing levels of anxiety, bodily pain and exhaustion, and for raising levels of vitality, mental health, general health and flexibility. This type of intervention could be seen as a low-cost strategy for improving the well-being of workers.

Inherited muscular abnormalities are debilitating disorders that greatly diminish the quality of life in affected individuals. Mutations in proteins such as dystrophin and caveolin, which together with other proteins form structural connections between the cytoskeleton and the extracellular matrix, are frequently the culprit of muscular dystrophies. In this case report, we describe a patient with a novel pathogenic dystrophin mutation co-existing with a caveolin-3 deletion. While genetically composed of this unique combination, the patient phenotypically presented with a primary clinical manifestation of Duchenne muscular dystrophy (DMD) in contrast to other cases of dual mutations in dystrophin and dystrophin-associated proteins.
RESUMO
INTRODUCTION: The Surviving Sepsis Campaign was developed to improve outcomes for all patients with sepsis. Despite sepsis being the primary cause of death after thermal injury, burns have always been excluded from the Surviving Sepsis efforts. To improve sepsis outcomes in burn patients, an international group of burn experts developed the Surviving Sepsis After Burn Campaign (SSABC) as a testable guideline to improve burn sepsis outcomes. METHODS: The International Society for Burn Injuries (ISBI) reached out to regional or national burn organizations to recommend members to participate in the program. Two members of the ISBI developed specific "patient/population, intervention, comparison and outcome" (PICO) questions that paralleled the 2021 Surviving Sepsis Campaign [1]. SSABC participants were asked to search the current literature and rate its quality for each topic. At the Congress of the ISBI, in Guadalajara, Mexico, August 28, 2022, a majority of the participants met to create "statements" based on the literature. The "summary statements" were then sent to all members for comment with the hope of developing an 80% consensus. After four reviews, a consensus statement for each topic was created or "no consensus" was reported. RESULTS: The committee developed sixty statements within fourteen topics that provide guidance for the early treatment of sepsis in burn patients. These statements should be used to improve the care of sepsis in burn patients. The statements should not be considered as "static" comments but should rather be used as guidelines for future testing of the best treatments for sepsis in burn patients. They should be updated on a regular basis. CONCLUSION: Members of the burn community from the around the world have developed the Surviving Sepsis After Burn Campaign guidelines with the goal of improving the outcome of sepsis in burn patients.

BACKGROUND: A vascular access team (VAT) was created in 2018 with the aim of improving vascular access and reducing complications associated with catheters. The impact of the introduction of a VAT in the insertion and maintenance of peripheral insertion central catheters (PICCs) was assessed. The cost-benefit associated with the use of a VAT was evaluated and the satisfaction of patients and professionals interacting with the VAT was measured. METHODS: In a prospective study, 275 PICCs inserted by the VAT were assessed for their impact on complications. PICCs were implanted with maximum barrier measures using an ultrasound with IC-ECG. Also, patient and professional satisfaction have been analysed thought a questionnaire over the phone or online, and hospital financial data was used to assess the cost impact of the insertion methodology followed by the VAT versus Anaesthesia Service. RESULTS: The thrombosis rate was 2.5% (7) and the bacteraemia rate was 1.1% (3). The use of the IC-ECG was correlated with a lower complication than the RX + IC-ECG (OR = 3.28, p = 0.021). In addition, there was a high level of perceived satisfaction for the patients surveyed and for the healthcare professionals involved in the care and management of these devices. The calculated saving for the implementation of the VAT was 61.81% compared with PICCs implanted in Anaesthesia Service. CONCLUSION: Low complication rates and high overall satisfaction scores in patients and professionals were observed, showing that a specialist VAT can have a positive impact in the insertion of PICCs and which also has a clear economic benefit.

(1) Background: COVID-19 infection is responsible for the ongoing pandemic and acute cerebrovascular disease (CVD) has been observed in COVID-19 patients. (2) Methods: We conducted a retrospective, observational study of hospitalized adult patients admitted to our hospital with SARS-CoV-2 and acute cerebrovascular disease. All clinical data were reviewed including epidemiology, clinical features, laboratory data, neuroradiological findings, hospital management and course from 32 patients hospitalized for COVID-19 management with acute cerebrovascular disease. (3) Results: Acute CVD with COVID-19 was associated with higher NIH stroke scale on discharge compared to non-COVID-19 CVDs. Seizures complicated the hospital course in 16% of COVID-19 patients with CVD. The majority of the acute CVDs were ischemic (81%) in nature followed by hemorrhagic (22%). Acute CVD with COVID-19 resulted in average hospital stays greater than twice that of the control group (13 days in COVID-19, 5 days in control). Acute CVD with COVID-19 patients had worse clinical outcomes with 31% patient deaths and 6% discharged to hospice. In the control group, 6% of patients died. (4) Conclusions: Acute CVD associated with COVID-19 tends to be more complicated with unique and adverse clinical phenotype, longer hospital admissions, and worse clinical outcomes.
RESUMO
Following a screen for neuromuscular mouse mutants, we identified ostes, a novel N-ethyl N-nitrosourea-induced mouse mutant with muscle atrophy. Genetic and biochemical evidence shows that upregulation of the novel, uncharacterized transient receptor potential polycystic (TRPP) channel PKD1L2 (polycystic kidney disease gene 1-like 2) underlies this disease. Ostes mice suffer from chronic neuromuscular impairments including neuromuscular junction degeneration, polyneuronal innervation and myopathy. Ectopic expression of PKD1L2 in transgenic mice reproduced the ostes myopathic changes and, indeed, caused severe muscle atrophy in Tg(Pkd1l2)/Tg(Pkd1l2) mice. Moreover, double-heterozygous mice (ostes/+, Tg(Pkd1l2)/0) suffer from myopathic changes more profound than each heterozygote, indicating positive correlation between PKD1L2 levels and disease severity. We show that, in vivo, PKD1L2 primarily associates with endogenous fatty acid synthase in normal skeletal muscle, and these proteins co-localize to costameric regions of the muscle fibre. In diseased ostes/ostes muscle, both proteins are upregulated, and ostes/ostes mice show signs of abnormal lipid metabolism. This work shows the first role for a TRPP channel in neuromuscular integrity and disease.

West syndrome consists of the triad of infantile spasms, characteristic electroencephalogram (EEG) pattern of hypsarrythmia and developmental delay. Infantile spasms generally occur in infants during the first year of life. There are different genetic mutations and syndromes associated with infantile spasms. We report the case of a white 14-month-old boy who developed infantile spasms and was found to have a 5q14.3 deletion.

BACKGROUND: The new characteristics of today's population, together with the presence of chronic diseases in the elderly, require a new approach to care, promoting coordination between different levels of care. In this sense, we find the figure of the nurse case manager (NCM) in primary health care mainly responsible for ensuring continuity of care in complex patients with chronic diseases. OBJECTIVE: to describe the role of the NCM in care management, determining its effectiveness in addressing chronic disease (health outcomes and quality of life) and its efficiency in the health system. METHODS: Bibliographic review of scientific evidence on case management applied to nursing. Between March and April 2020 a bibliographic search was carried out in the Dialnet, Scielo, Scopus and Pubmed databases. INCLUSION CRITERIA: articles written in the last 5 years, which analyze how this nursing rol influences the care and health of patients. RESULTS: A total of 16 articles were selected. The NCM reduced the use of the emergency department, hospital admissions, readmissions, and the duration of these in the patients studied. CONCLUSION: The NCM is effective and efficient for both patients and health institutions, and a common practice model is needed that includes standardized protocols and evidence-based practices.

OBJECTIVE: The purpose of this manuscript is to review the various etiologies and to discuss the therapeutic issues in childhood stroke. METHODS: A PubMed search of literature pertaining to childhood stroke was conducted from 1983 to 2008 using specific key search words pertinent to cerebrovascular disorders in childhood. RESULTS: The analysis of the multiple causes of childhood stroke including arterial ischemic strokes and cerebral venous thrombosis was presented. Current therapy and outcome data in childhood stroke are also discussed throughout the length of the article. CONCLUSIONS: With increasing vigilance among physicians and improved neuroimaging modalities, the diagnosis of childhood stroke is now made earlier, with increasing frequency and greater accuracy. However, larger and well-controlled studies regarding the optimal management of childhood stroke in terms of the use of both antithrombotic drugs and anticoagulation are still needed in addition to longitudinal follow-up studies of children with stroke.

We present a case of a young girl complaining of headaches in whom a hypointense area was found in the pituitary gland with a standard magnetic resonance (MR) image of the head. This finding did not agree with clinical symptoms, so a dedicated MR of the sellar region was obtained. We determined that the supposed mass was artifact caused by volume averaging. Volume averaging is the effect of expressing the average density of two structures of a 3D slice on a 2D image. Increased slice thickness leads to increased volume averaging and decreased resolution. Dedicated MR uses thinner 3D slices to reconstruct an image and thus has better spatial resolution than standard MR. We emphasize the need of dedicated MR to evaluate pituitary lesions.

Epilepsy, including the type with focal onset, is increasingly viewed as a disorder of the brain network. Here we employed the functional connectivity (FC) metrics estimated from the resting state functional MRI (rsfMRI) to investigate the changes of brain network associated with focal epilepsy caused by single cerebral cavernous malformation (CCM). Eight CCM subjects and 21 age and gender matched controls were enrolled in the study. Seven of 8 CCM subjects underwent surgical resection of the CCM and became seizure free and 4 of the surgical subjects underwent a repeat rsfMRI study. We showed that there was both regional and global disruption of the FC values among the CCM subjects including decreased in homotopic FC (HFC) and global FC (GFC) in the regions of interest (ROIs) where the CCMs were located. There was also the disruption of the default mode network (DMN) especially the FC between the middle prefrontal cortex (MPFC) and the right lateral parietal cortex (LPR) among these individuals. We observed the trend of alleviation of these disruptions after the individual has become seizure free from the surgical resection of the CCM. Using a voxel-based approach, we found the disruption of the HFC and GFC in the brain tissue immediately adjacent to the CCM and the severity of the disruption appeared inversely proportional to the distance of the brain tissue to the lesion. Our findings confirm the disruption of normal brain networks from focal epilepsy, a process that may be reversible with successful surgical treatments rendering patients seizure free. Some voxel-based metrics may help identify the epileptogenic zone and guide the surgical resection.

OBJECTIVE: The purpose of this manuscript is to review various clinical and neuroimaging features of vascular pathology in the fetus and neonate. METHODS: A PubMed search of literature from 1978 to 2007 was performed using key search terms. Scientific papers pertinent to fetal and neonatal strokes were included and analysed. RESULTS: The analysis of the multiple causes of fetal and neonatal vascular compromise including maternal, placental, infectious, metabolic/prothrombotic, traumatic and cardiac factors, current therapy and outcome data, is presented and discussed throughout the length of the paper. CONCLUSION: With increasing vigilance among physicians and improved neuroimaging modalities, the diagnosis of neonatal stroke is now made earlier, with increasing frequency and greater accuracy.

Neonatal withdrawal from maternal drugs and medications is common in some NICUs. Codeine-containing cough preparations given to pregnant mothers have been identified as a cause of neonatal abstinence syndrome. However, many women do not consider prescription cough syrups when asked about drug use. Maternal medication or illicit drug use has been identified as a cause of perinatal arterial stroke. Since codeine is an opiate with similar pharmacodynamic effects to morphine, it is reasonable to investigate if maternal codeine use has effects on the fetus that are similar to other opiates. The authors present 2 cases of newborn infants with perinatal arterial stroke that may have been associated with in utero exposure to codeine. Physicians should ask about maternal medication use, including codeine-containing cough preparations, when evaluating newborn infants with evidence of cerebral infarction.

OBJECTIVES: Prior to enactment of the Affordable Care Act(ACA), several reports demonstrated remarkable racial disparities in access to surgical care for epileptic patients. Implementation of ACA provided healthcare access to 7-16 million uninsured Americans. The current study investigates racial disparity post ACA era in (1) access to surgical management of drug-resistant temporal lobe epilepsy (DRTLE); (2) short-term outcomes in the surgical cohort. PATIENT AND METHODS: Adult patients with DRTLE registered in the National Inpatient Sample (2012-2013) were identified. Association of race (African Americans and other minorities with respect to Caucasians) with access to surgical management of TLE, and short-term outcomes [discharge disposition, length of stay (LOS) and hospital charges] in the surgical cohort were investigated using multivariable regression techniques. RESULTS: Of the 4062 patients with DRTLE, 3.6%(n=148) underwent lobectomy. Overall, the mean age of the cohort was 42.35±16.33years, and 54% were female. Regression models adjusted for patient demographics, clinical and hospital characteristics demonstrated no racial disparities in access to surgical care for DRTLE. Likewise, no racial disparity was noted in outcomes in the surgical cohort. CONCLUSION: Our study reflects no racial disparity in access to surgical care in patients with DRTLE post 2010 amendment of the ACA. The seismic changes to the US healthcare system may plausibly have accounted for addressing the gap in racial disparity for epilepsy surgery.

This revision to the EEG Guidelines is an update incorporating the current electroencephalography technology and practice. It was previously published as Guideline 2. Similar to the prior guideline, it delineates the aspects of Guideline 1 that should be modified for neonates and young children. Recording conditions for photic stimulation and hyperventilation are revised to enhance the provocation of epileptiform discharges. Revisions recognize the difficulties involved in performing an EEG under sedation in young children. Recommended neonatal EEG montages are displayed for the reduced set of electrodes only since the montages in Guideline 3 should be used for a 21-electrode 10-20 system array. Neonatal documentation is updated to use current American Academy of Pediatrics term "postmenstrual age" rather than "conceptional age." Finally, because therapeutic hypothermia alters the prognostic value of neonatal EEG, the necessity of documenting the patient's temperature at the time of recording is emphasized.

BACKGROUND: Psammoma bodies (PBs) are whorled, laminated hyaline spherules containing calcium deposits. Intracranially, the presence of PBs is associated with variants of meningioma and pituitary lesions, as well as aging choroid plexus. Limited information exists on their presence in vascular malformation. RESULTS: In this report, we describe a case of an adolescent male with drug-resistant epilepsy that was surgically managed at our regional epilepsy center. The epileptogenic focus was determined to be emanating from an indolent right insular lesion. Histopathologic evaluation showed the abundance of intravascular and perivascular PBs. Immunohistochemical evaluation confirmed the vascular origin using vascular markers. The unusual presence of PBs in a vascular lesion was unanticipated. CONCLUSIONS: Based on our case, we present the clinicoradiologic characteristics, supplemented with intraoperative findings, for this unusual lesion. In addition, because of the unusual presence of PBs in vascular lesions, we provide the findings of a systematic literature review to show the association of PBs with intracranial vascular lesions.

Megalencephalic leukoencephalopathy with subcortical cysts is a rare leukodystrophy characterized by macrocephaly and a slowly progressive clinical course marked by spasticity and cognitive decline. We report two full siblings with neuroimaging studies and clinical courses typical for megalencephalic leukoencephalopathy with subcortical cysts, in whom a pair of novel mutations in the MLC1 gene was identified. We review the current knowledge of this disorder in relation to the patients reported.
