Presentations and Outcomes Among Infants ≤90 Days With and Without SARS-CoV-2.

OBJECTIVES: To compare symptoms and outcomes among infants aged ≤90 days tested for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in a broad, international sample of emergency departments (EDs). METHODS: This was a secondary analysis of infants aged 0 to 90 days with suspected SARS-CoV-2 infections tested using molecular approaches and with 14-day follow-up. The parent studies were conducted at 41 EDs in 10 countries (the global Pediatric Emergency Research Network; March 2020-June 2021) and 14 EDs across Canada (Pediatric Emergency Research Canada network; August 2020-February 2022). Symptom profiles included presence and number of presenting symptoms. Clinical outcomes included hospitalization, ICU admission, and severe outcomes (a composite of intensive interventions, severe organ impairment, or death). RESULTS: Among 1048 infants tested for SARS-CoV-2, 1007 (96.1%) were symptomatic at presentation and 432 (41.2%) were SARS-CoV-2-positive. A systemic symptom (any of the following: Apnea, drowsiness, irritability, or lethargy) was most common and present in 646 (61.6%) infants, regardless of SARS-CoV-2 status. Although fever and upper respiratory symptoms were more common among SARS-CoV-2-positive infants, dehydration, gastrointestinal, skin, and oral symptoms, and the overall number of presenting symptoms did not differ between groups. Infants with SARS-CoV-2 infections were less likely to be hospitalized (32.9% vs 44.8%; difference -11.9% [95% confidence interval (CI) -17.9% to -6.0%]), require intensive care (1.4% vs 5.0%; difference -3.6% [95% CI -5.7% to -1.6%]), and experience severe outcomes (1.4% vs 5.4%; difference -4.0% [95% CI -6.1% to -1.9%]). CONCLUSIONS: SARS-CoV-2 infections may be difficult to differentiate from similar illnesses among the youngest infants but are generally milder. SARS-CoV-2 testing can help inform clinical management.

Evaluation of short-term adverse events of COVID-19 vaccines: An observational study.

Coronavirus disease 2019 (COVID-19) vaccines are the most effective tools in managing the pandemic. However, the concern about these vaccines is the occurrence of unwanted adverse events (AEs). This study aimed to evaluate the short-term AEs of COVID-19 vaccines (Sputnik V, Astrazenka, and Sinopharm). A cross-sectional study using an online questionnaire was conducted among 321 vaccinated individuals. Demographic information, history of drug use, prior infection with COVID-19, the type of vaccine, vaccination stage, local injection site complication, systemic complication, and allergic reactions were collected and evaluated. Local complications, including pain and swelling at the injection site, and systemic complications, including fever, fatigue, lethargy, lymphadenopathy, and diarrhea, were reported after the injection of the AstraZeneca vaccine was more than the other 2 vaccines; The prevalence of fatigue and lethargy was higher than other systemic complications. The least reported complication was due to lymphadenopathy. The Sinopharm vaccine showed a lower prevalence of AEs than the other 2. The rare AEs, such as facial paralysis, nasal bleeding, and urticarial, were further reported after injection of the AstraZeneca vaccine. In general, the severity of systemic complications after the second dose of the vaccine was also higher than the first dose. All 3 vaccines were safe and tolerable. The most commonly reported AEs were injection site pain (local) and fatigue and lethargy (systemic). These expected AEs occurred shortly after vaccination and indicated an early immune response after vaccination.

Exploring Subfactors of Adult Cognitive Disengagement Syndrome and Impact on Neuropsychological Performance.

OBJECTIVE: This study investigated subfactors of cognitive disengagement syndrome (CDS; previously referred as sluggish cognitive tempo) among adults referred for neuropsychological evaluation of attentiondeficit/hyperactivity disorder (ADHD). METHOD: Retrospective analyses of data from 164 outpatient neuropsychological evaluations examined associations between CDS subfactors and self-reported psychological symptoms and cognitive performance. RESULTS: Factor analysis produced two distinct but positively correlated constructs: "Cognitive Complaints'' and "Lethargy." Both correlated positively with symptom reports (rs = 0.26-0.57). Cognitive Complaints correlated negatively with working memory, processing speed, and executive functioning performance (rs = -0.21 to -0.37), whereas Lethargy correlated negatively only with processing speed and executive functioning performance (rs = -0.26 to -0.42). Both predicted depression symptoms, but only Cognitive Complaints predicted inattention symptoms. Both subfactors demonstrated modest to nonsignificant associations with cognitive performance after accounting for estimated premorbid intelligence and inattention. CONCLUSION: Findings indicate a bidimensional conceptualization of CDS, with differential associations between its constituent subfactors, reported symptoms, and cognitive performance.

Management of Choroid Plexus Tumors and the Benefit of Preoperative Embolization in Pediatric Patients: Report of 46 Cases from a Single Institution.

OBJECTIVE: Optimal choroid plexus tumor (CPT) treatment involves gross total resection; however, intraoperative hemorrhage risk remains significant given tumor vascularity. This study describes pediatric CPT management and identifies patients most likely to benefit from preoperative embolization. METHODS: CPTs resected from 1997 to 2021 were included. The characteristics of embolized patients were compared to nonembolized patients; nonembolized patients were further stratified based on open vascular control-pedicle feeder ligation versus no pedicle ligation prior to tumor debulking. Statistical analyses identified factors associated with estimated blood loss (EBL), transfusion, length of stay, and complications. RESULTS: Among the 46 CPT cases identified, 98% achieved gross total resection, and 15% received embolization. Embolized patients were younger, smaller, and had larger tumors compared to nonembolized patients (median: 0.8 vs. 2.1 years; 9.3 vs. 14.4 kg; 91.08 vs. 5.5 cm3). Transfused patients were similarly younger and smaller (P < 0.05) than nontransfused patients. Among nonembolized patients, open vascular control was achieved in smaller tumors (<13 cm3) with significantly lower EBL (P = 0.002). Higher EBL was observed in patients with larger tumors, hydrocephalus, transependymal edema, vomiting, lethargy, and developmental regression (all P < 0.05). Patients with lethargy had longer hospital stays and a higher likelihood of postoperative complications (P < 0.05). There were no significant differences in complication rates between the embolization and nonembolization groups. CONCLUSIONS: Despite higher surgical risk profiles, embolized patients had similar complication rates and postoperative hydrocephalus management as nonembolized patients. Embolization was particularly beneficial in patients at high risk for surgical morbidity, such as those <2 years, weighing <10 kg, and with a tumor volume >15 cm3.

Associations Between Eating, Mobility, and Toileting Functional Dependence and COVID-19 Symptoms.

OBJECTIVES: The first goal of this study was to explore associations between functional dependence levels during activities of daily living (eg, functional mobility, eating, and toileting) before COVID-19 and presence of COVID-19 symptoms (eg, fever, dehydration, lethargy, and shortness of breath) during illness. The second goal of this study was to explore associations between presence of specific COVID-19 symptoms and level of functional decline from before to after illness. DESIGN: Retrospective cohort study. SETTING AND PARTICIPANTS: A total of 375 residents at a single skilled nursing facility in New York City. METHODS: Data were extracted from the Minimum Data Set 3.0 and chart reviews. Multiple linear regressions analyzed relationships between baseline functional dependence in eating, functional mobility, and toileting and presence of dehydration, lethargy, shortness of breath, and fever. Ordinal linear regressions analyzed associations between COVID-19 symptom presence and changes in functional dependence from before to after illness. RESULTS: Pre-COVID-19 eating dependence was significantly associated with dehydration during COVID-19. Dehydration during COVID-19 was significantly associated with greater functional declines in functional mobility from before to after illness. Shortness of breath was significantly associated with increased functional declines in eating and functional mobility. CONCLUSIONS AND IMPLICATIONS: Patients with COVID-19 should be monitored for shortness of breath and dehydration, as these symptoms are associated with functional decline. Individuals experiencing functional decline before COVID-19 onset are especially vulnerable to these symptoms. Future research should further explore the relationship between functional status and COVID-19 symptoms.

Changes in depression symptom profile with gender-affirming hormone use in transgender persons.

BACKGROUND: Women show higher prevalence of depression and different symptomatology than men, possibly influenced by sex hormones. Many transgender persons, who face a high risk of depression, use Gender-Affirming Hormone Therapy (GAHT), but the impact of GAHT on depressive symptom profiles is unknown. METHODS: This study examined depressive symptoms in transgender persons before GAHT and after 3- and 12 months of GAHT. We used the Inventory of Depressive Symptomatology-Self Report to assess depressive symptoms, exploratory factor analysis (EFA) to assess symptom clusters, and linear mixed models to assess changes in symptom clusters. RESULTS: This study included 110 transmasculine (TM) and 89 transfeminine (TF) participants. EFA revealed four symptom clusters: mood, anxiety, lethargy, and somatic symptoms. Changes in total depressive symptoms significantly differed between TM and TF groups. After 3 months of GAHT, TM participants reported improvement in lethargy (-16 %; 95%CI: -29 %; -2 %), and after 12 months TF participants reported worsening in low mood (24 %; 95%CI: 3 %; 51 %), but absolute score changes were modest. Neither group showed changes in anxiety or somatic symptoms. LIMITATIONS: This study had limited sample sizes at 12 months follow-up and did not include relevant biological or psychosocial covariates. DISCUSSION: Changes in depressive symptoms after GAHT use differ in TM and TF persons: TM persons report slight improvements in lethargy, whereas TF persons report a slight increase in low mood. Starting GAHT represents a significant life event with profound social and physical effects, and further research should assess social and biological effects of GAHT on mood-related symptoms.

Comparison of clinical and laboratory characteristics between severe and non-severe dengue in paediatrics.

BACKGROUND: The timely identification of severe dengue in peadiatric patients is of utmost importance, as any delay in diagnosis could lead to an irreversible state of shock potentially leading to fatal consequences. The primary aim of our study was to characterize dengue severity in paediatric patients based on initial symptoms, signs, and laboratory investigation of their presentation in the emergency department. METHODOLOGY: We conducted a retrospective data retrieval from the medical records of 254 paediatric patients who had been diagnosed with confirmed cases of dengue fever. The clinical characteristics were compared between severe and non-severe dengue. Multiple logistic regression analysis was utilised to elucidate the variables that exhibited associations with severe dengue. RESULTS: A total of 254 paediatric patients were included, among whom 15.4% (n = 39) were diagnosed with severe dengue. Multiple logistic regression analysis identified lethargy, systolic blood pressure (SBP) below 90 mmHg, capillary refilled time (CRT) longer than 2 seconds, ascites, and hepatomegaly were independently associated with severe dengue. CONCLUSION: In paediatric patients, severe dengue is associated with specific clinical indicators, including lethargy, low systolic blood pressure, prolonged capillary refill time (CRT), and the presence of ascites and hepatomegaly. Identifying these clinical features early is crucial for primary care physicians, as it enables accurate diagnosis and timely intervention to manage severe dengue effectively.

AN OUTBREAK OF FELINE INFECTIOUS PERITONITIS IN THREE RELATED SAND CATS (FELIS MARGARITA) IN HUMAN CARE.

Feline infectious peritonitis (FIP) is a systemic disease in felid species caused by infection with mutated forms of feline coronavirus (FCoV), and outbreaks can devastate exotic felid populations in human care. Feline infectious peritonitis was diagnosed in three of four related juvenile sand cats (Felis margarita) from a single institution over a 6-wk period. Case 1 was a 7-mon-old male found deceased with no premonitory signs. Case 2, an 8-mon-old male (littermate to Case 1), and Case 3, a 6-mon-old male (from a different litter with identical parentage), were evaluated for lethargy and anorexia 1 mon after Case 1. Both exhibited transient anisocoria and progressive lethargy, anorexia, and dehydration despite antibiotic and supportive treatment. Approximately 1 wk after initial presentation, Case 2 was humanely euthanized, and Case 3 was found deceased. Necropsy findings included intrathoracic and/or intra-abdominal lymphadenopathy (3/3 cases), bicavitary effusion (2/3), multifocal tan hepatic and intestinal nodules (1/3), and multifocal yellow renal nodules (1/3). Histologically, all cats had severe pyogranulomatous vasculitis in multiple organs, and the presence of FCoV antigen was confirmed using immunohistochemical staining. Next-generation sequencing of the virus from Case 3's affected kidney demonstrated ∼93% homology to the UG-FH8 virus, a serotype 1 feline alphacoronavirus isolated from Denmark. Future research will focus on comparative viral genomic sequencing with the goals of identifying potential sources of FCoV infection and identifying features that may have contributed to the development of FIP in this species.

Experimental sickness reduces hypocretin receptor 1 expression in the lateral hypothalamus and ventral tegmental area of female mice.

Recent studies have focused on how sickness behaviours, including lethargy, are coordinated in the brain in response to peripheral infections. Decreased hypocretin (orexin) signalling is associated with lethargy and previous research suggests that hypocretin signalling is downregulated during sickness. However, there are studies that find increases or no change in hypocretin signalling during sickness. It is further unknown whether hypocretin receptor expression changes during sickness. Using lipopolysaccharide (LPS) to induce sickness in female mice, we investigated how LPS-injection affects gene expression of hypocretin receptors and prepro-hypocretin as well as hypocretin-1 peptide concentrations in brain tissue. We found that hypocretin receptor 1 gene expression was downregulated during sickness in the lateral hypothalamus and ventral tegmental area, but not in the dorsal raphe nucleus or locus coeruleus. We found no changes in hypocretin receptor 2 expression. Using a gene expression calculation that accounts for primer efficiencies and multiple endogenous controls, we were unable to detect changes in prepro-hypocretin expression. Using radioimmunoassay, we found no change in hypocretin-1 peptide in rostral brain tissue. Our results indicate that hypocretin receptor expression can fluctuate during sickness, adding an additional level of complexity to understanding hypocretin signalling during sickness.

Macular Star, Optic Disc Swelling, and Lethargy in a Child.

A 13-year-old girl with a 7-day history of painless vision loss and central scotoma in her left eye was referred to the hospital. Dilated fundus examination revealed a bilateral sectorial macular star that was more extended in the left eye and some faint, small, tan-yellow dots were observed at the level of the retinal pigment epithelium in the posterior pole. What would you do next?

Clinical Reasoning: An Older Woman With Headaches and Lethargy After a Fall.

In this case, a 77-year-old woman presented with generalized weakness, difficulty ambulating, lethargy, loss of appetite, and headaches after a mechanical fall. This case discusses the management of acute neurologic emergencies such as subdural hematoma, status epilepticus, and bacterial meningitis. Potential etiologies for stroke and CNS infection are highlighted. Readers are led through the diagnostic approach to a patient presenting with a complex array of neurologic symptoms causing rapid clinical decompensation.

Trends in menstrual cycle symptoms, physical activity avoidance, and hormonal contraceptive use in a general population of adult women.

INTRODUCTION: Research examining symptoms and side effects of the menstrual cycle on physical activity performance and participation has almost exclusively focussed on elite and athletic populations. The current study aimed to i) identify any differences in symptomatic experiences of the menstrual cycle between hormonal contraceptive users and non-users, ii) gain insight into hormonal contraceptive use, iii) describe perceived symptomatic influences on physical activity engagement, and iv) identify perceived levels of knowledge and understanding around the menstrual cycle. METHODS: An online questionnaire was completed by 881 adult females aged between 18 and 55 years. Questionnaire items related to hormonal contraceptive use, habitual physical activity levels, experiences and symptoms of the menstrual cycle, and sources of information resulting in knowledge and understanding of the menstrual cycle. RESULTS: More than half of all participants (52%) identified themselves as being recreationally active, and the most commonly reported menstrual symptoms were abdominal cramps, lethargy, abdominal bloating, lower back pain, and heavy bleeding. Of all respondents, 48.1% were using some form of hormonal contraception, 66% of which were using a version of a combined oral contraceptive pill. DISCUSSION: Consistent with previous studies, 90% of respondents regularly experienced adverse menstrual symptoms, including abdominal cramps, lethargy, abdominal bloating, lower back pain, and heavy bleeding. Menstrual symptoms were frequently identified as influential factors in the avoidance of, and reduced performance in, physical activity. Almost half of all participants were using some form of hormonal contraception, a noticeably larger proportion than has been previously documented in studies examining non-athletic populations.

Prevalence of post-vaccine side effects among COVID-19 immunized community of Southern Pakistan.

BACKGROUND: The response to the vaccine may vary among individuals. Hence, it is important to know how often individuals experience side effects after immunization against COVID-19. OBJECTIVE: This study aimed to assess the incidence of side effects following COVID-19 vaccination across different vaccine recipients in Southern Pakistan and identify the potential factors associated with these side effects in the population. METHODS: The survey was conducted across Pakistan through Google-forms Links from August to October 2021. The questionnaire included demographic information and COVID-19 vaccine information. Chi-square (x2) was performed for comparative analysis to check the significance level with P <0.05. The final analysis included 507 participants who had received COVID-19 vaccines. RESULTS: Of the total 507 COVID-19 vaccines recipients, 24.9% received CoronaVac, 36.5% received BBIBP-CorV, 14.2% received BNT162b2, 13.8% received AZD1222, and 10.7% received mRNA-1273. The most prominent side effects after the first dose were fever, weakness, lethargy, and pain at the site of injection. Moreover, the most commonly reported side effects after the second dose were pain at the injection site, headache, body ache, lethargy, fever, chills, flu-like symptoms, and diarrhea. CONCLUSION: Our results suggested that the side effects due to COVID-19 vaccination can vary between the first and second doses and type of COVID-19 vaccine. Our findings suggest continuing monitoring of vaccine safety and the importance of individualized risk-benefit assessment for COVID-19 immunization.

Children with severe enterovirus A71 infection.

BACKGROUND: There are few reports on the timing of onset and the symptoms of enterovirus A71 (EV-A71) infection, which can easily be misdiagnosed. This study aimed to explore the clinical characteristics of children with severe EV-A71 infection. METHODS: This retrospective observational study included children with severe EV-A71 infection admitted to Hebei Children's Hospital between January 2016 and January 2018. RESULTS: A total of 101 patients were included: 57 males (56.4%) and 44 females (43.6%). They were 1-13 years of age. The symptoms were fever in 94 patients (93.1%), rash in 46 (45.5%), irritability in 70 (69.3%), and lethargy in 56 (55.4%). There were 19 (59.3%) patients with abnormal neurological magnetic resonance imaging [pontine tegmentum (n = 14, 43.8%), medulla oblongata (n = 11, 34.4%), midbrain (n = 9, 28.1%), cerebellum and dentate nucleus (n = 8, 25.0%), basal ganglia (n = 4, 12.5%), cortex (n = 4, 12.5%), spinal cord (n = 3, 9.3%), and meninges (n = 1, 3.1%)]. There was a positive correlation between the ratio of neutrophil count and white blood cell count in cerebrospinal fluid in the first 3 days of the disease (r = 0.415, P < 0.001). CONCLUSION: The clinical symptoms of EV-A71 infection are fever and/or skin rash, irritability, and lethargy. Some patients have abnormal neurological magnetic resonance imaging. The white blood cell count in the cerebrospinal fluid of children with EV-A71 infection may increase alongside neutrophil counts.

A 44-Year-Old Woman With Prolonged Fever and Mediastinal "Lymphadenopathy".

CASE PRESENTATION: A 44-year-old woman with a history of dyslipidemia and chronic anemia from uterine fibroids was admitted to the general medicine department of a tertiary hospital for a prolonged fever of 2 months' duration. The patient reported multiple visits to her local general practitioner, with tympanic temperatures up to 38.2 °C, where she was treated with 2 courses of broad-spectrum antibiotics in view of associated sore throat, nonproductive cough, and generalized lethargy. Although her respiratory symptoms abated within a few days of her initial presentation, her fever and lethargy persisted. Initial chest radiograph was unremarkable. Subsequent CT scan of the thorax, abdomen, and pelvis detected an enlarged subcarinal lymph node measuring 3.7 cm × 1.7 cm and a mildly enlarged pre-carinal lymph node measuring 2.0 × 1.5 cm, with a mean attenuation of 66-77 Hounsfield Units (HU), and no central necrosis or calcification. No significant abnormalities were detected in the abdomen or pelvis. The patient was then referred to the respiratory department for further evaluation.
