The effect of motor learning-based telerehabilitation on quality of life of children with cerebral palsy during the COVID-19 pandemic.

BACKGROUND: During the pandemic, the access of children with cerebral palsy (CP) to rehabilitation services was adversely affected due to the significant risk of infection. AIMS: We assessed whether the effect of a motor learning-based treatment provided via a telerehabilitation method on the quality of life of children with cerebral palsy during the COVID-19 period was equivalent to face-to-face treatment. METHODS: Distance exercises were explained by a physiotherapist to the patients in the telerehabilitation group, and motor learning-based treatment was applied by their families; the physiotherapist followed the sessions with video conferencing. Motor learning-based treatment was offered to the face-to-face group by a physiotherapist in the clinic. RESULTS: In the comparison between the groups, there was a significant difference in the parameters of play activities, pain-hurt, fatigue, eating activities, and speech communication activities after treatment (p<0.05). However, in the test performed by considering the nonhomogeneous parameters before the treatment, no time-dependent difference was found in the repeated measurements before and after the treatment in all parameters (p>0.05). CONCLUSION: Motor learning-based treatment provided using the telerehabilitation method has a positive effect on the quality of life of children with CP, but the results are similar to face-to-face treatment.

Late-Onset Seizure Disorder in Adult Cerebral Palsy Associated With COVID-19 Infection.

COVID-19 can affect many organ systems, including the CNS, with symptoms of altered mental status and seizures. We present a case of a 30-year-old man with cerebral palsy who developed seizures after a COVID-19 infection. Admission labs were remarkable for hypernatremia, and elevated creatine kinase, and troponin levels as well as creatinine above baseline. MRI was performed demonstrating a small, evolving acute/subacute abnormality in the midline splenium of the corpus callosum. An EEG showed moderate to severe abnormalities with low-voltage delta waves. The patient was treated with medication and advised to follow up with a neurologist. One month later, no residual CT abnormality corresponding to the previously reported lesion in the midline splenium of the corpus callosum was observed. Although epilepsy is a common finding in patients with cerebral palsy, the complete lack of seizure activity throughout this patient's early life, coupled with previously unremarkable brain imaging, further supports our claim that his recent onset of seizures was directly related to COVID-19. This case highlights the possibility of new seizures in patients with pre-existing neurological conditions after COVID-19 infection and emphasizes the need for more research.

Challenges Experienced by Mothers of Children with Cerebral Palsy during the Movement Control Order (Lockdown) in Malaysia: A Qualitative Study

Background and Purpose: Following the global coronavirus (COVID-19) outbreak and the recent spike in COVID-19 cases in Malaysia, the Malaysian government had imposed a Movement Control Order (MCO) on 16 March 2020 as a measure to curb the outbreak. Consequently, all non-essential affairs were suspended and operated fully on a work-from-home basis, when schools were temporarily closed, and citizens were urged to stay at home. Despite a high number of studies on the negative impacts of MCO to various sectors, there is a little concern noted for the potential impacts on vulnerable populations, including parents with special kids such as cerebral palsy (CP). The purpose of this qualitative study was to investigate the burdens and difficulties associated with the experience of caring for children with CP during the MCO Methodology: This study was designed as qualitative research. Twenty-six participants were selected using a purposive sampling method to involve in in-depth interviews. They were the parents who joined the Cerebral Palsy Support Group in Terengganu, Malaysia. The interview responses were thematically analyzed using a content analysis method. Findings: Four main themes were revealed from the thematic analysis, namely emotional distress, worry over postponement of therapy and medical consultation, burn out due to work from home, and conditions of the CP children themselves. The findings indicated that both mothers, either working or housewife, experienced depression and deterioration in physical health and psychosocial emotions. Contributions: Interventions in the forms of financial aids, guidance for CP children self-therapy at home, and emotional supports are urgently needed to ensure mothers and their CP children maintain their quality of life despite the MCO.

COVID-19 in people with developmental disabilities: a scoping review

Objective: To examine the emerging evidence on developmental disability type and frequency in the population affected by COVID-19, identifying more frequent forms of categorization, incidence/prevalence and comorbidities.Methods: For this scoping review, we searched for observational studies in the MEDLINE (PubMed), Scopus (Elsevier), ISI Web of Science (Clarivate), LILACS (VHL) and grey literature databases. As eligibility criteria, studies should present results of developmental disability (DD) occurrence in people with COVID-19, allowing comparison with the general population, or between groups of disabilities. Two independent reviewers mapped the information using a previously elaborated data extraction instrument. Two other researchers verified the data and assisted in table elaboration to present the results.Results: There was a diversity of terminologies used to categorize DD. People with DD and comorbidities that represent a higher risk for COVID-19 required hospitalization more frequently than the general population. Out of a total of 4930 studies, 14 were selected for assessment. Of these, 5 articles were longitudinal studies.Conclusion: In people with DD, COVID-19 had higher morbidity, lethality and mortality rates in younger age groups, in the poorest population, in the institutionalized population, requiring life support technologies and specialized care. The vulnerability of people with DD to COVID-19 depends on disease type and severity and the presence of comorbidities, highlighting the need for attention in diagnosis and preventive measures, such as vaccination.

The Relationship between the Functionality of Children with Disabilities and Its Effects on Parents during the Covid-19 Pandemic Process

Purpose: The aim of this study was to investigate the relationship between the functionality of disabled children and its effects on parents during the Covid-19 pandemic. Methods: A total of 168 people, including 84 disabled children and 84 mothers, were included in the study. The Pediatric Disability Assessment Inventory (PEDI) and Gross Motor Function Classification System (GMFCS) were used for children with disabilities. The Zarit Burden Scale (ZBS), Fatigue Severity Scale (FSS) and The Nordic Musculoskeletal Questionnaire (NMQ) were applied to the mothers to question musculoskeletal disorders. Results: There was no correlation between care burden score and PEDI, total score, self-care and mobility scores (p>0.05). A moderately negative (r=-0.306;p<0.01) significant linear relationship was found between care burden score and social function score. There was no significant linear relationship between the fatigue severity score and PEDI total score, self-care, mobility and social function scores (p>0.05). No correlation was found between care burden score and fatigue severity score (p>0.05). For the last 12 months, only the pain in the lumbar region of the parents prevented them from doing their usual work. It was determined that the most aching body parts of the parents who complained of musculoskeletal pain during the last 12 months were in the waist, neck, shoulder, back, and knee regions. Conclusion: As a result, no relationship was found between the functionality of disabled children and their parents' influences during the Covid-19 pandemic.

Structure of Patients and Outcome of the Triage Process for the Dental Treatment in General Anesthesia

Introduction: Aim of the study was to analyse the structure of patients referred for dental treatment in general anaesthesia (GA) and to analyse the triage outcomes. Material(s) and Method(s): Retrospective chart analysis of patients referred between January 1st 2018 and July 7th 2022 was performed. Following data were registered: age, sex, diagnosis/ reason for referral for GA, indication for dental treatment in GA, trisage outcome and waiting time for the GA procedure. Result(s): Charts of 193 referred in the aforementioned period were analysed. Most common reason for the referral was autism (65/33.7%), cerebral paralysis (29/15%) and mental retardation (27/14%). Indication for dental treatment in GA was found in 156(80.8%) patients while in 37(19.2%) patients no indication for dental treatment in GA was found. Out of the 156 patients who were indicated for dental treatment in GA, 98(62.8%) patients were managed through day-care surgery and 8(5.2%) patients were admitted to hospital. Twenty patients (12.8%) were still waiting for their GA appointment in the time of analysis, 29(18.6%) were lost to follow up and in one (0.6%) patient the anaesthesiologist recommended ambulatory treatment due to increased risk. Out of the 37 patients in whom no indication for the treatment in GA was found, 13(35.2%) had no caries, 16/ (43.2%) were referred to paediatric dentist and 8(21.6%) were managed on the initial exam. Median time of waiting for the procedure was 120(10-365) days. Before the COVID- 19 pandemics median waiting time was 90(15-300) days, and after the COVID-19 pandemics median waiting time was 135(10-365) days. Conclusion(s): In the majority of the patients referred for dental treatment in GA, indication for the procedure was established. Majority of the referred patients can be managed through a day-care surgery. COVID-19 pandemics is probably one of the reasons for the increased GA procedure waiting time.

Status dystonicus in a patient with cerebral palsy and COVID-19.

Introduction: status dystonicus (SD) is a rare condition characterized by generalized and intense exacerbation of muscle contractions. Objective(s): to present a pediatric patient with SD associated with COVID-19. Case report: 3-year old male with cerebral palsy. He was admitted to the emergency room after four days with respiratory symptoms, which were accompanied by increased muscle tone, generalized dystonia, and febrile seizures. In laboratory tests, COVID-19 was confirmed, as well as an elevation of creatine phosphokinase (CPK), 16,000 U/L. Diagnosis of SD is established, recovering after receiving medical management. Conclusion(s): SD can cause serious complications, so it is essential to identify possible triggers in patients with greater susceptibility.Copyright © 2022 Authors. All rights reserved.

Automated Fact-Checking of Articles Related to Neurodevelopmental Disorders

False claims or Fake News related to the health care or medicine field on Social Media have garnered increasing amounts of interest, especially in the aftermath of the COVID-19 pandemic. False claims about the pan-demic which spread on social media have contributed to vaccine hesitancy and lack of trust in the advise of medical professionals. If not detected and disproved early, such claims can complicate future pandemic responses. We focus on false claims in the field of Neurodevelopmental Disorders (NDDs), which is an umbrella term for a group of disorders that includes Autism, ADHD, Cerebral Palsy, etc. In this paper we present our approach to automated systems for fact-checking medical articles related to NDDs. We also present an annotated dataset of 116 web pages which we use to test our model and present our results. © 2022 IEEE.

Physiotherapy in Neurological conditions: AB No: 81: Tele-rehabilitation program for Balance and Coordination training in Cerebral Palsy Children: A Pilot Study

Purpose: To evaluate the effect of tele-rehabilitation on balance and coordination training in cerebral palsy children. Relevance: COVID-19 pandemic had significant impact on children with disability due to prolonged confinement at home which influenced negative physical status of children. Tele-rehabilitation can play a major role in the maintenance of function, prevention of worsening disability, and follow up of patient. It can proves beneficial to the family by decreasing time and costs related to travelling, family centered service, home based model of delivery of care which leads to being less prone to infection. Participants: 9 Children with cerebral palsy in the age group of 6–12 years with GMFCS level I and II were recruited from the paediatric out-patient department and child developmental centre of a tertiary care hospital and special schools in Belagavi. Methods: In this pre-post pilot study, pre-treatment and post-treatment outcomes were taken by using balance and bilateral coordination subtest of Bruininks Oseretsky Test of motor proficiency 2 (BOT2). The physiotherapy treatment consisted of conventional balance training exercise via tele-rehabilitation through Whats App video call. The intervention was carried out thrice a week for 4 weeks for one hour which was monitored by the therapist and assistance was provided by the parent. Statistical Analysis: The data was analysed using paired t test. Results: The results indicated a significant improvement in balance (P =0.042) with mean difference-4.25 ± 3.20 and coordination with mean difference-4.25 ± 1.50 (P=0.011). Conclusion: This study showed that tele-rehabilitation as a mode of treatment for children with cerebral palsy is useful for training balance and coordination. Implications: Tele-rehabilitation can be considered as an effective mode of delivering rehabilitation for children with cerebral palsy and that the effect must be studied in a larger sample size.

Special considerations in the premature and ex-premature infant

Advances in neonatal medicine have progressively increased the survival of premature infants. Increased survival has however come at the cost of increased number of infants with prematurity-related complications. This is represented by high rates of respiratory distress syndrome, bronchopulmonary dysplasia (BPD), necrotizing enterocolitis (NEC), sepsis, periventricular leukomalacia (PVL), intraventricular haemorrhage (IVH), cerebral palsy, hypoxic ischaemic encephalopathy (HIE) and visual and hearing problems in survivors. In addition to prolonged hospital stay after birth, readmission to hospital in the first year of life is common if chronic lung disease exists. Around 3% of newborns have a congenital physical anomaly with 60% of congenital anomalies affecting the brain or heart and around 1% having multiple anomalies. Individual congenital conditions requiring surgical intervention in the neonatal period are rare. Neonates have a higher perioperative mortality risk largely due to the degree of prior illness, the complexity of their surgeries, and infant physiology. The maintenance of oxygenation and perfusion in the perioperative phase is critical as both affect cerebral perfusion and neurocognitive outcome but the triggers for intervention and the thresholds of physiological parameters during neonatal anaesthesia are not well described. After even minor surgical procedures, ex-premature infants are at higher risk for postoperative complications than infants born at term.Copyright © 2022

The perceived impact of Covid-19 pandemic on the children with cerebral palsy: the parents' perspective explored within the "6-F words" framework.

BACKGROUND: In 2020 the world faced the spread of the coronavirus infection disease (Covid-19). This was a general public health emergency but many people with disabilities might have been particularly affected. OBJECTIVE: This paper aims to investigate the impact of the Covid-19 pandemic on children with Cerebral Palsy (CP) and their families. METHODS: 110 parents of children with CP (aged 2 to 19) who completed a questionnaire were included. These children were under the care of one of the Italian Children Rehabilitation Centers. Socio-demographic and clinical information about patients and their families were collected. In addition, difficulties on adopting protective measures and in respecting lockdown rules by children were explored. We adopted the ICF (International Classification of Functioning, Disability and Health) framework to create multiple choice questions. Descriptive statistics were reported and logistic regression analyses were run in order to identify the predictors of perceived impairment in motor, speech, manual and behavioral abilities. RESULTS: Daily activities of children, as well as rehabilitation and fitness sessions, underwent a change during the pandemic. Spending more time with family due to lockdown measures, has had, in some cases a positive effect however there was a perceived decrease in rehabilitation support and school activities. The age range (between 7 and 12 years) and difficulty in respecting rules emerged as significant predictors of the perceived impairment due to Covid-19 pandemic. CONCLUSIONS: The pandemic has had different impacts on children and their families on the basis of children's characteristics. Rehabilitation activities during a hypothetic lockdown should consider these characteristics.

Can wrist-worn devices and a smartphone application influence arm activity in children with unilateral cerebral palsy? A proof-of-concept study.

Aim: To determine whether a wrist-worn triaxial accelerometer-based device and software (including smartphone application), incorporating feedback, is feasible, acceptable, and can lead to increased affected upper limb use during everyday activities in children with unilateral cerebral palsy (UCP). Methods: Study design: Mixed methods proof of concept study. Participants: Children aged 8-18 years with UCP; age-matched typically developing controls ("Buddies"), therapists. Intervention: Baseline (2 weeks): devices recorded arm activity. Active feedback (6 weeks): devices also gave vibratory prompts if affected arm activity fell below pre-set personalised thresholds (UCP group only; control group continued as per Baseline). Final 2 weeks: as baseline. Both groups accessed a smartphone application providing feedback on relative arm motion throughout the study. Assessment and analysis: ABILHAND-Kids questionnaires and MACS classifications captured baseline participant characteristics (UCP group). Accelerometer data was used to calculate relative arm activity (signal vector magnitude) corrected for time worn/day, and trends in relative arm activity examined using single case experimental design (both groups). In-depth interviews with families, "Buddies" and therapists assessed feasibility and acceptability of implementation. A framework approach was used for qualitative data analysis. Results: We recruited 19 participants with UCP; 19 buddies; and 7 therapists. Five participants (two with UCP) did not complete the study. Baseline mean (stdev) ABILHAND-Kids score of children with UCP who completed the study was 65.7 (16.2); modal MACS score was II.Qualitative analysis demonstrated acceptability and feasibility of the approach. Active therapist input for this group was minimal. Therapists appreciated the potential for summary patient data to inform management. Arm activity in children with UCP increased in the hour following a prompt (mean effect size z = 0.261) for the non-dominant hand, and the dominant hand (z = 0.247). However, a significant increase in affected arm activity between baseline and intervention periods was not demonstrated. Discussion: Children with UCP were prepared to wear the wristband devices for prolonged periods. Whilst arm activity increased bilaterally in the hour following a prompt, increases were not sustained. Delivery of the study during the COVID-19 pandemic may have negatively influenced findings. Technological challenges occurred but could be overcome. Future testing should incorporate structured therapy input.

Psychometric properties of the English language version of the C-BiLLT evaluated in typically developing Canadian children.

PURPOSE: This study aimed to 1) investigate the convergent and discriminant validity, internal consistency, and test-retest reliability of the Canadian English version of the Computer-Based instrument for Low motor Language Testing (C-BiLLT-CAN), and 2) explore feasibility of the C-BiLLT assessment for children with cerebral palsy (CP) and complex communication needs in the Canadian health care context. METHODS: Eighty typically developing children between 1.5 and 8.5 years of age completed the C-BiLLT-CAN, the Peabody Picture Vocabulary Test-IV (PPVT-4), the receptive language sub-test of the New Reynell Developmental Language Scales (NRDLS), and/or the Raven's 2. Correlations between raw scores were calculated for estimates of convergent and discriminant validity. Internal consistency was calculated for all items and separately for items pertaining to vocabulary and grammar. To calculate the standard error of measurement (SEM) and intraclass correlation coefficient (ICC), 33 participants were re-tested with the C-BiLLT within three weeks. Feasibility was explored with nine participants with CP. RESULTS: C-BiLLT-CAN's convergent validity was good to excellent (Spearman's rho > 0.78) and discriminant validity was higher than hypothesized (Spearman's rho > 0.8). Internal consistency (Cronbach's alpha = 0.96), test-retest reliability (ICC > 0.9), and measurement error (SEM < 5%) were excellent. The feasibility study could not be fully completed due to the COVID-19 pandemic. Preliminary data demonstrated some technical and practical barriers for using the C-BiLLT in children with CP in Canada. CONCLUSION: The C-BiLLT-CAN showed good to excellent psychometric properties in a sample of typically developing children, indicating that it is an adequate test for measuring language comprehension in English-speaking Canadian children. Further research is needed to investigate the feasibility of the C-BiLLT-CAN in children with CP.

The impact of the COVID-19 pandemic on children with disabilities and their parents or caregivers.

Objectives: The study aimed to determine the impact of the pandemic on parents/caregivers and children with neurologic disabilities. Patients and methods: This multi-center cross-sectional study was conducted with 309 parents/caregivers (57 males, 252 females) and their 309 children (198 males, 111 females) with disabilities between July 5, 2020, and August 30, 2020. The parents/caregivers were able to answer the questions and had internet access. The survey included questions on the utilization of educational and health care services (whether they could obtain medicine, orthosis, botulinum toxin injection, or rehabilitation) during the pandemic. A Likert scale was used to evaluate the effect of the specific health domains, including mobility, spasticity, contractures, speech, communication, eating, academic, and emotional status. The Fear of COVID-19 Scale was used to assess fear of COVID-19. Results: Among the children, 247 needed to visit their physician during the pandemic; however, 94% (n=233) of them could not attend their physician appointment or therapy sessions. The restricted life during the first wave of the pandemic in Türkiye had negatively affected 75% of the children with disabilities and 62% of their parents. From the perspective of the parents/caregivers, mobility, spasticity, and joint range of motion of the children were affected. Forty-four children required repeated injections of botulinum toxin; however, 91% could not be administered. The Fear of COVID-19 Scale scores were significantly higher in the parents who could not bring their children to the routine physician visit (p=0.041). Conclusion: During the pandemic, access to physical therapy sessions was disrupted in children with neurological disabilities, and this may have harmful consequences on the functional status of children.

Early Short-Term Use of Different Doses of Corticosteroid in Hospitalized Pediatric Patients with Coronavirus Disease 2019 Pneumonia

Objective Encouraged by reports of favorable outcomes following the use of corticosteroids in patients with moderate-to-severe coronavirus 2019 (COVID-19) pneumonia, we aimed to present our experience with early short-term corticosteroid use at our center in pediatric patients with COVID-19 pneumonia. Methods One hundred and twenty-nine pediatric patients were included in the study. Patients were divided into four groups according to the type and dose of corticosteroids given: Group 1 (those receiving dexamethasone 0.15 mg/kg/d);Group 2 (those receiving methylprednisolone 1 mg/kg/d);Group 3 (those receiving methylprednisolone 2 mg/kg/d);and Group 4 (those receiving pulse methylprednisolone 10-30 mg/kg/d). Results Of 129 patients, 19 (14.7%) patients were assigned to Group 1, 30 (23.3%) patients to Group 2, 30 (23.3%) patients to Group 3, and 50 (38.8%) patients to Group 4. Thirty-two (24.8%) patients were followed in the pediatric intensive care unit (PICU), of whom 13 (10%) required mechanical ventilation, and 7 (%5.4) died. In Group 4, the hospitalization length was significantly longer than in other groups (p < 0.001, p < 0.001). No significant difference was found among the groups in terms of mortality (p = 0.15). The most common comorbidity was obesity (33%). A significant association was found between the presence of comorbidity and mortality (p < 0.001). All patients who died had an underlying disease. Cerebral palsy was the most common underlying disease among the patients who died. Worsening of lymphopenia was significant in patients with severe COVID-19 pneumonia at the time of transfer to the PICU (p = 0.011). Conclusion Although children usually have a milder course of COVID-19 than adults, underlying diseases and obesity increase the severity of disease manifestations also in children. Further studies are needed to define the exact role of corticosteroids in COVID-19 patients. © 2022. Thieme. All rights reserved.

Attitude of Parents of Children with Cerebral Palsy Towards COVID-19 Vaccination.

Children with cerebral palsy (CP) are at a greater risk of respiratory complications from coronavirus disease 2019 (COVID-19). Therefore, this study aimed to assess COVID-19 vaccine hesitancy (VH) among parents of CP children in Egypt, using the Arabic version of the Parental Attitude about Childhood Vaccination (PACV) questionnaire. This cross-sectional survey study was conducted at the outpatient clinics of two hospitals in Cairo, Egypt. Parents of children with CP were recruited using a simple random sampling technique. A total of 321 parents were enrolled; more than half of them were mothers of the children (61.37%); and the majority were Egyptians (87.23%) and living in urban areas (84.42%). Nearly 70% of the parents were hesitant to administer the COVID-19 vaccine to their children. A multiple linear regression model revealed that the PACV mean scores were lower among the following categories: (1) parents who could pay back loans, compared to those who could not pay back loans and who reported insufficient income (ß = -2.39, p = 0.030); (2) non-Egyptian parents (ß = -1.54, p = 0.002); (3) those who were fully vaccinated against COVID-19 themselves or had the intention to receive the complete COVID-19 vaccination (ß = -6.28, p < 0.001); (4) those who had the intention to give the COVID-19 vaccination to their children (ß = -3.04, p < 0.001); and (5) parents whose children received routine vaccines (ß = -2.86, p < 0.045). After adjusting for other covariates, the parental COVID-19 vaccine status (ß = -6.28, p < 0.001) and parents who experienced a COVID-19-related death in the family (ß = -1.75, p < 0.001) showed significantly lower mean PACV scores. However, higher mean PACV scores were reported among parents who had a COVID-19 infection (ß = 2.77, p < 0.001) or who were not sure (ß = 2.94, p < 0.001). Our findings suggest the need to increase COVID-19 vaccine acceptance among parents of vulnerable children to reduce the negative consequences of COVID-19.

Therapeutic Effects of Metaverse Rehabilitation for Cerebral Palsy: A Randomized Controlled Trial.

Metaverse physical therapy (MPT), an adjuvant technology for the rehabilitation of children with cerebral palsy (CP), has gained notoriety in the clinical field owing to its accessibility and because it provides motivation for rehabilitation. The aim is to compare the gross motor function and cardiopulmonary function, the activities of daily living, quality of life (QOL), and the perceived risk of coronavirus disease (COVID)-19 transmission between MPT and conventional physical therapy (CPT). A convenience sample of 26 children with CP (mean age, 11.23 ± 3.24 years, 14 females) were randomized into either the MPT or CPT group and received therapy three days/week for four weeks. Clinical outcomes included gross-motor-function measure 66 (GMFM-66), heart rate (HR), Borg-rating perceived exertion (BRPE), functional independence measure (FIM), pediatric QOL, and the risk of COVID-19 transmission. An analysis of variance showed that compared with CPT, MPT exerted positive effects on GMFM, HR, and BRPE. An independent t-test showed that compared with CPT, MPT exerted positive effects on the perceived transmission risk of COVID-19 but not on FIM and QOL. Our results provide promising therapeutic evidence that MPT improves gross motor function, cardiopulmonary function, and the risk of COVID-19 in children with CP.

Issue Highlights

2023;112 (1): 93 - 99. 5 Himmelmann K, Påhlman M. The panorama of cerebral palsy in Sweden part XIII shows declining prevalence in birth-years 2011-2014. The latest phase of this lengthy, ongoing study showed a significant decrease in the prevalence of cerebral palsy in children born from 2011 to 2014.[5] The decline was mainly seen in term-born children, while the prevalence in children born extremely preterm was unchanged. Sweden initially chose a different disease prevention and control path to many other countries during the COVID-19 pandemic. [Extracted from the article]
