Study on clinical profile, risk factors, morbidity and mortality patterns of intrauterine growth restricted babies admitted in neonatal intensive care unit of tertiary care hospital, Vijayapura

Background: Intrauterine growth restriction (IUGR) is an important clinical problem associated with increased perinatal mortality and morbidity. The neonate may be either constitutionally small or small due to pathophysiological changes with maternal, placental or foetal factors involved. A foetus with IUGR has not achieved its genetic growth potential. In addition, emerging evidence suggests that they are also more likely than normal weight babies to suffer from degenerative diseases like hypertension, diabetes and cardiovascular diseases in adulthood. Methods: This is a cross-sectional study carried out in the neonatal unit, tertiary care hospital, Vijayapura. This study was carried out between April 2022 to April 2024. 120 IUGR babies were included in this study. Results: Of the 120 babies 22 (18.3%) have died in the hospital. 19 (15.5%) have been discharged with abnormal neurological examination and 79 (66.3%) have been discharged with good condition at discharge condition. Morbidity pattern of IUGR shows that hypoglycaemia (63.3%) and perinatal asphyxia (45.0%) are the commonest complication. Other commoner are sepsis (33.3%), hypocalcaemia (30.0%), hypothermia (28.3%) and thrombocytopenia (25.0%). Conclusions: Perinatal asphyxia and meconium aspiration are significantly associated with abnormal neurological examination at discharge. Perinatal asphyxia, pulmonary haemorrhage and persistent PH are significantly associated with death during the hospital stay. 73 (77.5%) mothers had one or more risk factors. Malnutrition is the commonest (40.0%), other are anaemia (34.2%), pregnancy-induced hypertension (PIH) (18.3%), multiple gestations (8.3%) and lower age of the mother.

Profile of Patients Receiving Computed Tomography Scans for Mild Traumatic Brain Injury in a Tertiary Care Hospital in Ethiopia

Traumatic brain injury (TBI) is a leading contributor to emergency department (ED) mortalities in Ethiopia. Mild TBI patients comprise half of all TBI patients presenting for care in Ethiopia and have a high potential for recovery. As such, context-specific care-improving strategies may be highly impactful for this group of patients. This study examines the presentation and disposition of mTBI patients who received a computed tomography scan of the head (CTH) upon arrival at the largest teaching hospital in Ethiopia. A retrospective cohort study was conducted from 2018-2021 including patients >13 years old with a head injury and a Glasgow Coma Score of 13-15 who obtained a computed tomography scan of the head (CTH). Variables were collected from medical charts and single and multi-variable analyses assessed outcomes of clinically important TBI (ciTBI) requiring a neurosurgical procedure or admission. A total of 193 patients were included. They were predominantly young men with no comorbidities, injured in road traffic accidents or by assault, had stable vital signs and were treated in lower-acuity ED areas. A minority demonstrated focal deficits, and 29.5% of patients had ciTBI. Most patients were discharged from the ED, but 13% were taken for operative neurosurgical procedures and 10.4% were admitted to the neurosurgery ward for observation. ED stays ranged from 8 hours to 10 days, as patients waited for CT availability, neurosurgical decision, or transportation. Female sex was independently protective of ciTBI. Self-referral status was independently protective against operative intervention. Female sex and self-referral status were independently protective of a disposition of admission and/or going to the operating room. This study characterizes the mTBI subgroup of head injury patients in Ethiopia's busiest ED: predominantly healthy young men with low-acuity presentations and only a fraction with abnormal neurological examinations. Nonetheless, about one-third had clinically important TBI and a minority were taken for neurosurgical procedures or admission, with female sex and self-referral identified as protective factors. Meanwhile, many patients stayed in the ED for days due to social or other non-medical reasons. As TBI care in Ethiopia continues to improve, optimizing care for the mTBI subgroup is tantamount given their high recovery potential. This care will benefit from efficiently identifying those who need intervention or hospital level of care, and discharging those who do not.

Predictive Ability of Amplitude Integrated Electroencephalography for Adverse Outcomes in Neonates with Sepsis-Associated Encephalopathy: A Cohort Study.

The authors examined the prevalence of abnormal amplitude integrated electroencephalography (aEEG) patterns in neonates diagnosed with sepsis-associated encephalopathy (SAE). They recorded 36626min of aEEG in 75 study neonates. Encephalopathy was defined by the Brighton Collaboration Neonatal Encephalopathy criteria. Neonates with primary outcome [either non-survivors or survivors with abnormal neurological examination at discharge using Amiel-Tison assessment tool, n = 58, (77%)] were compared with 17 survivors having normal neurological examination at discharge. Severely abnormal aEEG patterns (isoelectric voltage, continuous low voltage, burst suppression) collectively represented 31% of total 36626min aEEG tracings. Neonates experiencing primary outcome had significantly higher Burdjalov scores than survivors with normal neurological exam (p value 0.01). After adjusting for gestational age, birth weight, and invasive ventilation, severely abnormal aEEG (aOR 5.8, 95% CI 1.7-19.5, p value 0.005) and Burdjalov score (aOR 0.77, 95% CI 0.63-0.95, p value 0.01) were independently associated with death or abnormal neurological examination at discharge.

Clinical Characteristics and Appropriateness of Investigations in Children With Headaches at the Emergency Department

BackgroundIdentifying the cause of headaches in pediatric emergency departments (PEDs) can be challenging due to the lack of comprehensive research. This study aims to identify the frequency, characteristics, and unnecessary diagnostic procedures of patients with headaches in the PED setting. MethodsA six-month cross-sectional study was conducted at the PED of Alexandria University Children's Hospital, including all children with headaches. Children were classified as having primary headache (PH), secondary benign headache (SBH), and secondary serious headache (SSH) according to predetermined criteria. Logistic regression was employed to analyze the risk factors associated with SSH. ResultsA total of 164 visits to the PED were recorded, out of a total of 22,662 visits, accounting for approximately 0.72% of all visits and 1.17% of the total number of children admitted. PH was the most common cause, accounting for 61.0% of cases, followed by SSH with 24.4%, whereas SBH was the least common with 13.4%. Abnormal neurological examination (odds ratio, 53.752 [1.628 to 1774.442], P = 0.026∗) was found to have a strong and statistically significant association with SSH in the multivariate analysis. Regarding the appropriateness of the investigations conducted, it was found that over half (66.5%) of the cases had unnecessary neuroimaging, with 52% of these cases being children with PH. ConclusionsHeadaches in children are commonly reported during visits to the PED. PH was the most prevalent, followed by SSH, whereas SBH was the least common. Many of the children received inaccurate first diagnoses and performed unnecessary laboratory tests, neuroimaging, and other tests, mostly electroencephalography.

Tuberous sclerosis complex in adulthood: focus on epilepsy prognosis

ObjectiveTypically diagnosed in early childhood or adolescence, TSC is a chronic, multisystemic disorder with age-dependent manifestations posing a challenge for transition and for specific surveillance throughout the lifetime. Data on the clinical features and severity of TSC in adults and on the prognosis of epilepsy are scarce. We analyzed the clinical and genetic features of a cohort of adult patients with TSC, to identify the prognostic predictors of seizure remission after a long follow-up. MethodWe conducted a retrospective analysis of patients diagnosed with TSC according to the updated international diagnostic criteria. Pearson’s chi-square or Fisher’s exact test and Mann Whitney U test were used to compare variables among the Remission (R) and Non-Remission (NR) group. Univariate and multivariate logistic regression analyses were performed. ResultsWe selected 43 patients with TSC and neurological involvement in terms of epilepsy and/or brain lesions, attending the Epilepsy Center of our Institute: of them, 16 (37.2%) were transitioning from the pediatric care and 6 (13.9%) were referred by other specialists. Multiorgan involvement includes cutaneous (86.0%), nephrological (70.7%), hepatic (40.0%), ocular (34.3%), pneumological (28.6%) and cardiac (26.3%) manifestations.Thirty-nine patients (90.7 %) had epilepsy. The mean age at seizure onset was 4 ± 7.3 years: most patients (29, 76.3 %) presented with focal seizures or spasms by age 3 years; only 2 (5.3 %) had seizure onset in adulthood. Twenty-seven patients (69.2 %) experienced multiple seizure types overtime, 23 (59.0 %) had intellectual disability (ID). At last assessment, 14 (35.9 %) were seizure free (R group) and 25 (64.1 %) had drug-resistant seizures (NR group). At logistic regression univariate analysis, ID (OR 7.9, 95 % CI 1.8––34.7), multiple seizure types lifelong (OR 13.2, 95 % CI 2.6– 67.2), spasms/tonic seizures at presentation (OR 6.5, 95 % CI 1.2––35.2), a higher seizure frequency at onset (OR 5.4, 95 % CI 1.2––24.3), abnormal neurological examination (OR 9.8, 95 % CI 1.1––90.6) and pathogenic variants in TSC2 (OR 5.4, 95 % CI 1.2––24.5) were significantly associated with non-remission. In the multivariate analysis, both ID and multiple seizure types lifelong were confirmed as independent predictors of poor seizure outcome. ConclusionsIn our cohort of adult patients with TSC, epilepsy remains one of the main neurological challenges with only 5.3% of cases manifesting in adulthood. Approximately 64% of these patients failed to achieve seizure remission. ID and multiple seizure types were the main predictors of poor outcome. Nephrological manifestations require continuous specific follow-up in adults.

Increasing Prevalence of Cerebral Palsy Among Two-Year-Old Children Born at

ObjectiveTo evaluate changes in prevalence and severity of cerebral palsy (CP) among surviving children born at <27 weeks of gestation over time and to determine associations between CP and other developmental domains, functional impairment, medical morbidities, and resource utilization among two-year old children who were born extremely preterm. Study DesignRetrospective cohort study using prospective registry data, conducted at 25 centers of the Eunice Kennedy Shriver NICHD Neonatal Research Network. Participants were children born at <27 weeks of gestation and followed at 18 through 26 months corrected age (CA) from 2008 through 2019. Outcomes of interest were changes in prevalence of any CP and severity of CP over time, and associations between CP and other neurodevelopmental outcomes, functional impairment, and medical comorbidities. Adjusted logistic, linear, multinomial logistic, and robust Poisson regression evaluated the relationships between child characteristics, CP severity, and outcomes. ResultsAmong 6,927 surviving children with complete follow-up data, 3,717 (53.7%) had normal neurologic examinations, 1,303 (18.8%) had CP, and the remainder had abnormal neurologic examinations not classified as CP. Adjusted rates of any CP increased each year of the study period (aOR 1.11 per year, 95% CI 1.08-1.14). Cognitive development was significantly associated with severity of CP. Children with CP were more likely to have multiple medical comorbidities, neurosensory problems, and poor growth at follow-up. ConclusionsThe rate of CP among surviving children who were born extremely preterm increased from 2008 through 2019. At 18 to 26 months CA, neurodevelopmental and medical comorbidities are strongly associated with all severity levels of CP.

Brachial Gunshot Wounds: Injury Patterns and Considerations for Managing the Abnormal Neurological Examination.

Nerve injuries from gunshot wounds (GSWs) to the upper arm can cause significant morbidity and loss of function. However, indications for surgical exploration and nerve reconstruction remain unclear as both low- and high-grade injuries can present with an abnormal neurological examination. Adult patients presenting with a history of isolated GSW to the upper arm between 2010 and 2019 at a single urban level 1 trauma center were screened for inclusion in this retrospective study. Patient demographics, neurological examination findings, concurrent injuries, and intraoperative findings were gathered. Bivariate analysis was performed to characterize factors associated with nerve injuries. There were 139 adult patients with isolated brachial GSWs, and 49 patients (35%) presented with an abnormal neurological examination and significantly associated with concurrent humerus fractures (39% vs 21%, P = .026) and brachial artery injuries (31% vs 2%, P < .001). Thirty of these 49 patients were operatively explored. Fifteen patients were found to have observed nerve injuries during operative exploration including 8 patients with nerve transections. The radial nerve was the most commonly transected nerve (6), and among the 16 contused nerves, the median (8) was most common. Nerve injury from upper arm GSWs is common with directly traumatized nerves confirmed in at least 39% and nerve transection in at least 16% of patients with an abnormal neurological examination. Timely referral to a hand and/or peripheral nerve surgeon for close clinical follow-up, appropriate diagnosis, and any necessary surgical reconstruction with nerve grafts, tendon transfers, and nerve transfers is recommended.

Three-year incidence and acute setting predictors of epilepsy after neonatal and childhood arterial ischaemic stroke: a disease-based cohort study.

This study identified specific and reliable acute clinical and imaging predictors of PSE in paediatric patients, helping clinicians identify high-risk patients with potential implications for treatment decisions. • Numerous risk factors have been proposed for post-stroke epilepsy, but there is a lack of studies evaluating these variables while accounting for confounding factors and competing risks over time. • After adjustment for competing events, acute symptomatic seizures, both non-status and status epilepticus, abnormal mental status or motor neurological examination at hospital discharge, cortical involvement, and multifocal ischaemic lesions in small strokes are all independent predictors of post-stroke epilepsy. • Knowing the predictors of post-stroke epilepsy is essential for clinicians to make well-informed and effective decisions about treatment.

Neurological manifestations in dogs with acute leukemia.

Canine acute leukemia is a rare hematopoietic neoplasm. Neurological abnormalities have been frequently reported in dogs with acute leukemia (AL). However, the description of the presentation and findings are limited. This study aimed to describe the clinical findings in dogs with acute leukemia presenting with neurological signs as their primary complaint. The database of a private referral hospital was searched for cases that presented to the neurological department with neurological deficits and were subsequently diagnosed with acute leukemia. Six cases were included; all had neurological clinical signs and an abnormal neurological examination. All cases had a focal neuroanatomical localisation on neurological examination (brain n = 4; spinal = 2). Out of the four dogs with a complete magnetic resonance imaging (MRI) study, there was an ill-defined infiltrative pattern with abnormal signal intensity in the central nervous system (CNS) in three dogs and the loss of grey and white matter differentiation in the brain (n = 2) and/or spinal cord (n = 2). Other MRI findings included abnormal meningeal enhancement (n = 3), changes affecting spinal nerves and epaxial muscles (n = 2), and lymphadenopathy in the field of view (n = 2). The bone marrow assessment on MRI showed evidence of signal change (n = 3), characterized by a loss of normal fat opacity and an abnormal degree of contrast enhancement. The cerebrospinal fluid (CSF) analysis of the four dogs showed an increased protein level with non-specific pleocytosis and without evidence of malignant cells. Treatment with cytotoxic medication was implemented in two dogs. The dogs diagnosed with acute leukemia had focal neuroanatomical localisation, an infiltrative CNS pattern, and bone marrow remodulation on MRI with an increase in CSF protein and negative cytology analysis.

X-linked Adrenoleukodystrophy Masquerading as Mood Disorder in an Adolescent Boy

X-linked adrenoleukodystrophy (ALD) is a demyelinating neurodegenerative disease of the brain with neurological manifestations in the majority of cases. However, a small proportion of cases also present solely with psychiatric symptoms. Here, we discuss the case of a 13-year-old boy presenting with mood symptoms, behavioral changes, and cognitive impairment. A neurodegenerative disease was suspected based on the atypical findings in history and abnormal neurological examination. Neuroimaging and pathogenic variations in the ABCD1 gene confirmed the diagnosis. Thorough history and detailed examination remain the cornerstone in arriving at the right diagnosis, aided by need-based advanced investigations.

Diagnostic accuracy of clinical and laboratory characteristics in suspected non-surgical nosocomial central nervous system infections

BackgroundThe diagnosis of meningitis in nonsurgical hospitalised patients is often difficult and diagnostic accuracy of clinical, laboratory, and radiological characteristics is unknown. MethodsIn a prospective multi-centre cohort study in the Netherlands with adults suspected of central nervous system (CNS) infections, we included consecutive patients who underwent a lumbar puncture for the suspicion of a nonsurgical nosocomial CNS infection. All episodes were categorized into five final clinical diagnosis categories, as reference standard: CNS infection, CNS inflammatory disease, systemic infection, other neurological disease, or non-systemic, non-neurological disease. Diagnostic accuracy of clinical characteristics, the index test, was assessed by determining sensitivity, specificity, and positive and negative predictive values (PPV; NPV). ResultsBetween 2012-2022, 114 of 1275 (9%) patients included in the cohort had suspected nonsurgical nosocomial CNS infection. Sixteen (14%) patients had a confirmed diagnosis of nonsurgical nosocomial CNS infection, including 4 (25%) with bacterial meningitis, 9 (56%) with viral CNS infections, 2 (13%) fungal meningitis and 1 (6%) parasitic meningitis. Diagnostic accuracy of individual clinical characteristics was generally low. Elevated CSF leukocyte count had the highest sensitivity (81%; 95% CI 54-96) and NPV (96%; 95% CI 90-99). When combining the presence of abnormalities in neurological or CSF examination, sensitivity for diagnosing a CNS infection was 100% (95% CI 79-100) and NPV 100% (95% CI 78-100). CSF examination changed clinical management in 47% of patients. ConclusionOf patients suspected of nonsurgical nosocomial CNS infections, 14% were diagnosed with such infections. Diagnostic accuracy for individual clinical characteristics was low, with elevated CSF leukocyte count having the highest sensitivity and NPV.

Retrospective Evaluation of Patients Admitted to the Pediatric Neurology Outpatient Clinic with Headache: Experience of a Tertiary Hospital.

It was aimed to determine the etiological and clinical features of pediatric patients with headache complaints. The files of patients who were admitted to the pediatric neurology outpatient clinic with headache were reviewed retrospectively. Patients' age, gender, features of headache, symptoms accompanying headache, available blood tests, brain magnetic resonance (MR) and electroencephalography (EEG) results were recorded. Of the total 470 patients, aged between 3 and 17 years, 291 (61.9%) were female and 179 (39.1%) were male. The mean age of the patients was 12.38±3.45 years. According to age groups, there were 16 (3.4%) patients under the age of 5, 159 (33.8%) between the ages of 6-11, and 295 (62.8%) patients aged 12-17 years. While 289 (61.5%) patients were diagnosed with primary headache, 122 (26.0%) patients were diagnosed with secondary headache, and headaches of 59 (12.5%) patients could not be classified. The most common primary headaches were tension-type headache (TTN) (n=177, 37.7%) and migraine (n=111, 23.6%). The 86 (70.5%) of the patients with secondary headache were diagnosed with sinusitis. Abnormal neurological examination finding was determined in 8 (1.7%) patients. Brain MR was performed in 439 (93.4%) of all patients and abnormal brain MR findings were detected in 52 (11.8%) patients. EEG was performed in 205 (43.6%) of all patients and abnormal EEG findings were detected in 24 (11.7%) patients. According to age groups, headache was most common in the 12-17 age group. The most common causes of headache were TTN and migraine, respectively. The most common secondary headache cause was sinusitis. We think that physical and neurological examination still maintains its priority in determining the causes of headache.

Update on Pediatric Spine Imaging.

The spine is often difficult to evaluate clinically in children, increasing the importance of diagnostic imaging to detect a wide variety of spinal disorders ranging from congenital abnormalities to severe infections. Clinical history and physical examination can help determine whether imaging is needed and which imaging technique would be best. The most common cause for back pain, even in children, is muscular strain/spasm that does not require any imaging. However, red flags such as pain at age < 5 years, constant pain, night pain, radicular pain, pain lasting > 4 weeks, or an abnormal neurologic examination may require further investigation. Imaging can be of great value for diagnosis but must be interpreted along with the clinical history, physical examination, and laboratory findings to achieve an accurate diagnosis. We discuss imaging for the most common and/or important spine pathologies in children: congenital and developmental pathologies, trauma, infectious processes, inflammatory causes, and tumors.

Epilepsy Frequency and Risk Factors Three Years After Neonatal Seizures

BackgroundNeonatal seizures, one of the main risk factors for the development of epilepsy, remain a clinical concern. In children with neonatal seizures, early recognition of risk factors is important for the early diagnosis and appropriate treatment of epilepsy and for improving prognosis. In this study, we aimed to determine the frequency of and the risk factors for the development of epilepsy in patients with neonatal seizures. MethodsThe hospital files of 228 children who experienced seizures in the neonatal period were reviewed. The frequency of epilepsy and risk factors for the development of epilepsy were determined at age 36 months. ResultsEpilepsy was diagnosed in 40.8% of the cases. Univariate analysis revealed family history of epilepsy, parental consanguinity, abnormal neurological examination findings, microcephaly, unresponsiveness to antiepileptic drugs or antiseizure medication, use of more than one antiepileptic drugs to antiseizure medication at discharge, status epilepticus, electroencephalography abnormalities, abnormal neuroimaging findings, invasive ventilation requirement, myoclonic seizures, central nervous system malformation, and congenital metabolic disease as risk factors for the development of epilepsy. Of these, a family history of epilepsy, abnormal neurological examination findings at discharge, and use of at least two antiepileptic drugs to antiseizure medication at discharge were found as independent risk factors in multivariate analysis. ConclusionsNeonatal seizures appear to be associated with epilepsy in more than one-third of the patients. Of the newborns with seizures, those with a family history of epilepsy, abnormal neurological examination findings at discharge, and those using at least two antiepileptic drugs to antiseizure medication at discharge should be monitored more carefully for the development of epilepsy.

Neurological and Psychological Sequelae Associated With Multisystem Inflammatory Syndrome in Children

Acute neurological involvement occurs in some patients with multisystem inflammatory syndrome in children (MIS-C), but few data report neurological and psychological sequelae, and no investigations include direct assessments of cognitive function 6 to 12 months after discharge. To characterize neurological, psychological, and quality of life sequelae after MIS-C. This cross-sectional cohort study was conducted in the US and Canada. Participants included children with MIS-C diagnosed from November 2020 through November 2021, 6 to 12 months after hospital discharge, and their sibling or community controls, when available. Data analysis was performed from August 2022 to May 2023. Diagnosis of MIS-C. A central study site remotely administered a onetime neurological examination and in-depth neuropsychological assessment including measures of cognition, behavior, quality of life, and daily function. Generalized estimating equations, accounting for matching, assessed for group differences. Sixty-four patients with MIS-C (mean [SD] age, 11.5 [3.9] years; 20 girls [31%]) and 44 control participants (mean [SD] age, 12.6 [3.7] years; 20 girls [45%]) were enrolled. The MIS-C group exhibited abnormalities on neurological examination more frequently than controls (15 of 61 children [25%] vs 3 of 43 children [7%]; odds ratio, 4.7; 95% CI, 1.3-16.7). Although the 2 groups performed similarly on most cognitive measures, the MIS-C group scored lower on the National Institutes of Health Cognition Toolbox List Sort Working Memory Test, a measure of executive functioning (mean [SD] scores, 96.1 [14.3] vs 103.1 [10.5]). Parents reported worse psychological outcomes in cases compared with controls, particularly higher scores for depression symptoms (mean [SD] scores, 52.6 [13.1] vs 47.8 [9.4]) and somatization (mean [SD] scores, 55.5 [15.5] vs 47.0 [7.6]). Self-reported (mean [SD] scores, 79.6 [13.1] vs 85.5 [12.3]) and parent-reported (mean [SD] scores, 80.3 [15.5] vs 88.6 [13.0]) quality of life scores were also lower in cases than controls. In this cohort study, compared with contemporaneous sibling or community controls, patients with MIS-C had more abnormal neurologic examinations, worse working memory scores, more somatization and depression symptoms, and lower quality of life 6 to 12 months after hospital discharge. Although these findings need to be confirmed in larger studies, enhanced monitoring may be warranted for early identification and treatment of neurological and psychological symptoms.

Neonatal brain MRI and short-term outcomes after acute provoked seizures

ObjectiveWe investigated how diagnosis and injury location on neonatal brain MRI following onset of acute provoked seizures was associated with short term outcome.Study designA multicenter cohort of neonates with acute provoked seizures enrolled in the Neonatal Seizure Registry. MRIs were centrally evaluated by a neuroradiologist for location of injury and radiologic diagnosis. Clinical outcomes were determined by chart review. Multivariate logistic regression was used to examine the association between MRI findings and outcomes.ResultsAmong 236 newborns with MRI at median age 4 days (IQR 3–8), 91% had abnormal MRI. Radiologic diagnoses of intracranial hemorrhage (OR 3.2 [1.6–6.5], p < 0.001) and hypoxic-ischemic encephalopathy (OR 2.7 [1.4–5.4], p < 0.003) were associated with high seizure burden. Radiologic signs of intracranial infection were associated with abnormal neurologic examination at discharge (OR 3.9 [1.3–11.6], p < 0.01).ConclusionFindings on initial MRI can help with expectant counseling on short-term outcomes following acute provoked neonatal seizures.

Peripheral Nerve Safety of Nerve Growth Factor Inhibition by Tanezumab: Pooled Analyses of Phase III Clinical Studies in Over 5000 Patients with Osteoarthritis.

Tanezumab, a humanized anti-nerve growth factor antibody, was developed for the treatment of pain associated with osteoarthritis. Due to its mechanism of action, peripheral nerve safety was assessed in all clinical studies. To summarize the neurological safety of intravenous (IV) and subcutaneous (SC) tanezumab versus placebo in patients with osteoarthritis. Data were pooled from 3389 patients across seven studies that investigated IV administration, and from 1840 patients across three studies that investigated SC administration. The treatment period of each study ranged from 16 to 24weeks, and follow-up periods ranged from 8 to 24weeks. Neurological safety evaluations focused on adverse events (AEs) of abnormal peripheral sensation (APS), neurologic examinations, and consultations. Across datasets, the incidence of AEs of APS was higher in tanezumab groups versus placebo. Paresthesia and hypoesthesia were the most frequently reported AEs in tanezumab-treated patients, compared with placebo. In both datasets, most AEs were of mild severity, resolved, and rarely resulted in discontinuation. In all treatment groups in both IV and SC studies, over 90% of patients had no new or worsened neurological examination abnormalities at the last study visit. Across datasets, mononeuropathy was diagnosed more frequently in tanezumab groups compared with placebo. Polyneuropathy was diagnosed in ≤ 0.9% of patients in tanezumab and placebo groups. Tanezumab IV or SC had an increased incidence of AEs of APS, such as paresthesia and hypoesthesia, and diagnoses of mononeuropathy compared with placebo. However, tanezumab was not associated with generalized peripheral neuropathy. NCT00733902, NCT00744471, NCT00830063, NCT00863304, NCT00863772, NCT01089725, NCT00985621, NCT02697773, and NCT02709486.

Increased newborn NICU admission for evaluation of hypoxic-ischemic encephalopathy during COVID-19 pandemic in a public hospital.

Prenatal and perinatal care of pregnant mothers has been adversely affected during the COVID-19 pandemic. Hypoxic-ischemic encephalopathy (HIE) is a leading cause of neonatal death and long-term neurological disabilities. Therapeutic hypothermia is effective for neonatal HIE. This study evaluated the effect of the pandemic on neonatal HIE. This retrospective single-center study compared neonatal HIE evaluation and hypothermia treatment between pre-COVID-19 pandemic (1 January 2018-31 December 2019) and COVID-19 pandemic (1 January 2020-31 December 2021) periods. Infants with abnormal neurological examination and or significant metabolic acidosis were admitted to NICU for evaluation of HIE and therapeutic hypothermia. Demographics, NICU admission and interventions, and neonatal outcomes were compared between infants born during the two periods using χ2, t-test, and Wilcoxon rank-sum test as appropriate. Statistical Process Control charts show the yearly proportion of infants evaluated for HIE and those treated with therapeutic hypothermia. From the pre-pandemic to the pandemic period, the proportion of infants that met HIE screening criteria increased from 13% to 16% (p < 0.0001), the proportion of infants admitted to NICU for HIE evaluation increased from 1% to 1.4% (p = 0.02), and the maternal hypertension rates of the admitted infants increased from 30% to 55% (p = 0.006). There was no difference in the proportions of the infants diagnosed with HIE (0.7% vs. 0.9%, p = 0.3) or treated with therapeutic hypothermia (0.2% vs. 0.3%, p = 0.3) between the two periods. There were no differences in the HIE severity and outcomes of the infants treated with therapeutic hypothermia between the two periods. During the COVID-19 pandemic, we observed a significant increase in NICU admission for HIE evaluation. While we did not find significant increases in neonatal HIE and the need for therapeutic hypothermia, larger studies are needed for a comprehensive assessment of the impact of the COVID-19 pandemic on neonatal HIE.

On-Field and Pitch-Side (Sideline) Assessment of Sports Concussion in Collision Sports: An Expert Consensus Statement Using the Modified Delphi Technique

To perform a Delphi consensus for on-field and pitch-side assessment of sports-related concussion (SRC). Open-ended questions in rounds 1 and 2 were answered. The results of the first 2 rounds were used to develop a Likert-style questionnaire for round 3. If agreement at round 3 was ≤80% for an item, if panel members were outside consensus, or there were >30% neither agree/disagree responses, the results were carried forward into round 4. The level of agreement and consensus was defined as 90%. Loss of consciousness (LOC) or suspected LOC, motor incoordination/ataxia, balance disturbance, confusion/disorientation, memory disturbance/amnesia, blurred vision/light sensitivity, irritability, slurred speech, slow reaction time, lying motionless, dizziness, headaches/pressure in the head, falling to the ground with no protective action, slow to get up after a hit, dazed look, and posturing/seizures were clinical signs of SRC and indicate removal from play. Video assessment is helpful but should not replace clinical judgment. LOC/unresponsiveness, signs of cervical spine injury, suspicion of other fractures (skull/maxillo-facial), seizures, Glasgow Coma Scale score <14 and abnormal neurologic examination findings are indications for hospitalization. Return to play should only be considered when no clinical signs of SRC are present. Every suspected concussion should be referred to an experienced physician. Consensus was achieved for 85% of the clinical signs indicating concussion. On-field and pitch-side assessment should include the observation of the mechanism, a clinical examination, and cervical spine assessment. Of the 19 signs and red flags requiring removal from play, consensus was reached for 74%. Normal clinical examination and HIA with no signs of concussion allow return to play. Video assessment should be mandatory for professional games but should not replace clinical decision-making. Sports Concussion Assessment Tool, Glasgow Coma Scale, vestibular/ocular motor screening, Head Injury Assessment Criteria 1, and Maddocks questions are useful tools. Guidelines are helpful for non-health professionals. Level V, expert opinion.

Serum Vitamin D status in full term neonates with severe perinatal depression.

Severe perinatal depression is a significant cause of mortality and morbidity in neonates. Vitamin D levels were observed to be low in mothers and their neonates with hypoxic ischemic encephalopathy in some studies, owing to its neuroprotective properties. Primary objective was to compare vitamin D deficiency state in full term neonates with severe perinatal depression and healthy term controls. Secondary objectives were to determine sensitivity and specificity of serum 25(OH)D<12 ng/mL in predicting mortality, development of hypoxic ischemic encephalopathy, abnormal neurological examination at discharge, and developmental outcome at 12 weeks of age. Serum 25(OH)D levels in full term neonates with severe perinatal depression and healthy controls were compared. Serum 25(OH)D levels in severe perinatal depression and controls (n = 55 each group) were significantly different (7.50 ± 3.53 ng/mL vs 20.23 ± 12.70 ng/mL). At cut-off of < 12 ng/mL, serum 25(OH)D could predict mortality with 100% sensitivity and 17% specificity and poor developmental outcomes with sensitivity of 100% and specificity of 50%. Vitamin D deficiency status at birth can serve as an effective screening tool and poor prognostic markers in term neonates with severe perinatal depression.
