Balanced crystalloids versus isotonic saline in pediatric sepsis: a comprehensive systematic review and meta-analysis.

Purpose: We conducted a comprehensive meta-analysis to compare the effects of balanced crystalloids (BC) and isotonic saline (IS) in pediatric sepsis. Methods: A systematic search was performed for studies comparing BC and IS in pediatric sepsis. Outcomes included mortality, acute kidney injury (AKI), need for renal replacement therapy (RRT), hospital length of stay (LOS), and pediatric intensive care unit (PICU) LOS. A random-effect models was used to calculated pooled odds ratios (OR) and mean differences (MD) with 95% confidence intervals (CIs). Results: The analysis included six studies with 8753 children. BC demonstrated significant reductions in overall mortality (OR 0.84, 95% CI 0.71 to 0.98, P = 0.03, I2 = 0%) and AKI (OR 0.74, 95% CI 0.57 to 0.96, P = 0.03, I2 = 37%) compared to IS. RRT need was similar between the BC and IS groups (OR 0.79, 95% CI 0.60 to 1.02, P = 0.07, I2 = 0%). Hospital and PICU LOS did not differ significantly. However, subgroup analysis of randomized controlled trials revealed significantly shorter hospital LOS in the BC group (mean difference -0.66 days, 95% CI -1.10 to -0.23, P = 0.003, I2 = 0%). Conclusion: Our meta-analysis demonstrates that using BC in pediatric sepsis is associated with reduced mortality, AKI, and hyperchloremia rates compared to IS, while maintaining similar hospital and PICU LOS. Large-scale randomized controlled trials are needed to validate these findings.

Anterolateral temporal lobe localization of dysnomia after temporal lobe epilepsy surgery.

Objectives: To evaluate what factors influence naming ability after temporal lobectomy in patients with drug-resistant epilepsy. Methods: 85 participants with drug-resistant epilepsy who underwent temporal lobe (TL) resective surgery were retrospectively identified (49 left TL and 36 right TL). Naming ability was assessed before and >3 months post-surgery using the Boston Naming Test (BNT).Multivariate lesion-symptom mapping was performed to evaluate whether lesion location related to naming deficits. Multiple regression analyses were conducted to examine if other patient characteristics were significantly associated with pre-to post-surgery changes in naming ability. Results: Lesion laterality and location were important predictors of post-surgical naming performance. Naming performance significantly improved after right temporal lobectomy ( p = 0.015) while a decrement in performance was observed following left temporal lobectomy ( p = 0.002). Lesion-symptom mapping showed the decline in naming performance was associated with surgical resection of the anterior left middle temporal gyrus (Brodmann area 21, r =0.41, p = <.001). For left hemisphere surgery, later onset of epilepsy was associated with a greater reduction in post-surgical naming performance ( p = 0.01). Significance: There is a wide range of variability in outcomes for naming ability after temporal lobectomy, from significant improvements to decrements observed. If future studies support the association of left anterior middle temporal gyrus resection and impaired naming this may help in surgical planning and discussions of prognosis.

Real-world effectiveness of COVID-19 vaccination in liver cirrhosis: a systematic review with meta-analysis of 51,834 patients.

SARS-CoV-2 vaccinations were found to be highly effective in phase 3 clinical trials. However, these trials have not reported data regarding the subgroup of liver disease or excluded patients with liver disease. The effectiveness of COVID-19 vaccines among liver cirrhosis (LC) patients is unclear. We conducted this meta-analysis to assess the effectiveness of SARS-CoV-2 vaccination in LC patients. A comprehensive literature search was conducted to include all the relevant studies that compared the outcomes of LC patients who received SARS-CoV-2 vaccines vs. unvaccinated patients. Pooled risk ratios (RRs) with 95% confidence intervals (CIs) were calculated by the Mantel-Haenszel method within a random-effect model. Four studies with 51,834 LC patients (20,689 patients received at least one dose vs 31,145 were unvaccinated) were included. COVID-19-related complications, including hospitalization (RR 0.73, 95% CI 0.59-0.91, P = 0.004), mortality (RR 0.29, 95% CI 0.16-0.55, P = 0.0001), and need for invasive mechanical ventilation (RR 0.29, 95% CI 0.11-0.77, P = 0.01), were significantly lower in the vaccinated group compared to the unvaccinated group. SARS-CoV-2 vaccination in LC patients reduced COVID-19-related mortality, intubation, and hospitalization. SARS-CoV-2 vaccination is highly effective in LC. Further prospective studies, preferably randomized controlled trials, are necessary to validate our findings and determine which vaccine is superior in patients with LC.

Modified Atkins diet versus ketogenic diet in children with drug-resistant epilepsy: A meta-analysis of comparative studies.

INTRODUCTION: The modified Atkins diet (MAD), a less restrictive form of the ketogenic diet (KD), has gained popularity and is proposed to be an alternative to the traditional KD in the management of drug-resistant epilepsy (DRE). However, the evidence to support this hypothesis remains limited. In this meta-analysis, we aimed to evaluate the efficacy and tolerability of MAD compared to traditional KD in children with DRE. METHOD: We systematically searched multiple databases through March 2022 for all the studies that evaluated the clinical utility of MAD versus KD for DRE in a pediatric population. The primary outcome was the proportion of children who had seizure frequency reduction (SFR) > 50%. The secondary outcomes were SFR >90%, seizure freedom, and diet-related side effects. All measurements were taken 6 months after starting the regimens. Pooled risk ratio (RR) and corresponding 95% confidence intervals (CIs) were calculated and combined using random-effects model meta-analysis. RESULTS: Six studies, with 397 patients with DRE (201 followed MAD vs. 196 with KD), were included. There was a significant difference in the proportion of patients who attained SFR >50% favoring the traditional KD (RR: 0.63; 95% CI: 0.47-0.83; P = 0.001). However, there was no significant differences in SFR >90% (RR: 0.73; 95% CI: 0.49-1.10; P = 0.13) or the proportion of patients who had seizure freedom (RR: 0.83; 95% CI: 0.49-1.41; P = 0.49). Furthermore, both regimens had comparable safety profiles (RR: 1.00; 95% CI: 0.95-1.05; P = 0.96). CONCLUSIONS: Our meta-analysis demonstrated the superiority of traditional KD over MAD in achieving SFR > 50% at 6 months in pediatric patients with DRE. However, SFR > 90% and seizure freedom were comparable between KD and MAD at 6 months. The tolerability profile between the two regimens was similar as well. Large-scale RCTs are necessary to validate our findings.

A Review of the Multi-Systemic Complications of a Ketogenic Diet in Children and Infants with Epilepsy.

Ketogenic diets (KDs) are highly effective in the treatment of epilepsy. However, numerous complications have been reported. During the initiation phase of the diet, common side effects include vomiting, hypoglycemia, metabolic acidosis and refusal of the diet. While on the diet, the side effects involve the following systems: gastrointestinal, hepatic, cardiovascular, renal, dermatological, hematologic and bone. Many of the common side effects can be tackled easily with careful monitoring including blood counts, liver enzymes, renal function tests, urinalysis, vitamin levels, mineral levels, lipid profiles, and serum carnitine levels. Some rare and serious side effects reported in the literature include pancreatitis, protein-losing enteropathy, prolonged QT interval, cardiomyopathy and changes in the basal ganglia. These serious complications may need more advanced work-up and immediate cessation of the diet. With appropriate monitoring and close follow-up to minimize adverse effects, KDs can be effective for patients with intractable epilepsy.

Clinical characteristics, management, and outcomes of CLIPPERS: A comprehensive systematic review of 140 patients from 100 studies.

INTRODUCTION: Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) is a rare inflammatory disorder of the central nervous system, characterized by symptoms referable to the brainstem and cerebellum such as, diplopia, gait ataxia and cerebellar dysarthria. The features and outcomes of CLIPPERS remains uncertain. we conducted this comprehensive systematic review to summarize all the existing studies that described CLIPPERS in the literature and to provide a quantitative assessment on the clinical characteristics, management, and outcomes of this rare syndrome. METHODS: A comprehensive search of PubMed and Web of Science databases was conducted from inception until January 15, 2022, was conducted. We only included the cases that clearly reported probable or definite diagnosis of CLIPPERS based on Taieb et al.'s criteria. The quality of the included studies was assessed using the JBI Critical Appraisal Tool. Descriptive statistics were performed to analyze the studies. Data were expressed as mean and standard deviation (SD) for continuous variables and proportions for categorical variables. RESULTS: We identified 100 case reports and series including a total of 140 patients with CLIPPERS (mean age: 46±18 years and males were 60%). The average follow-up duration was 32.27±57.8 months. Ataxia was the most common presenting symptom. Sixteen percent of the cases were associated with malignancy, mostly hematologic malignancies. The overall relapse rate was 59.2%, and the duration of steroid therapy was considerably shorter in the relapsed cases than in the non-relapsed (mean 6.19±7.9 vs. 10.14±12.1 days, respectively, P = 0.04). The overall mortality rate was 10%, but mortality in patients with malignancy was 30% and it was 12% in patients with relapses. In the case of steroid dosing (less than 20 mg/d versus greater than 20 mg/d) there was no significant modification in the risk of relapse. CONCLUSION: CLIPPERS is a rare clinical syndrome that affects mainly middle-aged males. Diagnosis of CLIPPERS is often challenging, and delays in diagnosis and treatment can lead to unfavorable outcomes. Therefore, neurologists should maintain a high index of suspicion for CLIPPERS in any patient presenting with symptoms and signs referrable to the brainstem. These patients should be screened for associated malignancies, especially hematological malignancies. The cases associated with malignancy tend to have worse outcomes. The relapse rate is relatively high. The relapse rate may be associated with worse mortality. Based on our findings, we recommend that CLIPPERS be treated with high-dose steroid therapy for at least ten days during the acute phase with a very slow taper. Prospective studies with a larger sample size are needed to validate our findings and guide the clinical care of these patients.

Clinical significance of micronutrient supplements in patients with coronavirus disease 2019: A comprehensive systematic review and meta-analysis.

BACKGROUND AND AIMS: Micronutrient supplements such as vitamin D, vitamin C, and zinc have been used in managing viral illnesses. However, the clinical significance of these individual micronutrients in patients with Coronavirus disease 2019 (COVID-19) remains unclear. We conducted this meta-analysis to provide a quantitative assessment of the clinical significance of these individual micronutrients in COVID-19. METHODS: We performed a comprehensive literature search using MEDLINE, Embase, and Cochrane databases through December 5th, 2021. All individual micronutrients reported by ≥ 3 studies and compared with standard-of-care (SOC) were included. The primary outcome was mortality. The secondary outcomes were intubation rate and length of hospital stay (LOS). Pooled risk ratios (RR) and mean difference (MD) with corresponding 95% confidence intervals (CI) were calculated using the random-effects model. RESULTS: We identified 26 studies (10 randomized controlled trials and 16 observational studies) involving 5633 COVID-19 patients that compared three individual micronutrient supplements (vitamin C, vitamin D, and zinc) with SOC. Nine studies evaluated vitamin C in 1488 patients (605 in vitamin C and 883 in SOC). Vitamin C supplementation had no significant effect on mortality (RR 1.00, 95% CI 0.62-1.62, P = 1.00), intubation rate (RR 1.77, 95% CI 0.56-5.56, P = 0.33), or LOS (MD 0.64; 95% CI -1.70, 2.99; P = 0.59). Fourteen studies assessed the impact of vitamin D on mortality among 3497 patients (927 in vitamin D and 2570 in SOC). Vitamin D did not reduce mortality (RR 0.75, 95% CI 0.49-1.17, P = 0.21) but reduced intubation rate (RR 0.55, 95% CI 0.32-0.97, P = 0.04) and LOS (MD -1.26; 95% CI -2.27, -0.25; P = 0.01). Subgroup analysis showed that vitamin D supplementation was not associated with a mortality benefit in patients receiving vitamin D pre or post COVID-19 diagnosis. Five studies, including 738 patients, compared zinc intake with SOC (447 in zinc and 291 in SOC). Zinc supplementation was not associated with a significant reduction of mortality (RR 0.79, 95% CI 0.60-1.03, P = 0.08). CONCLUSIONS: Individual micronutrient supplementations, including vitamin C, vitamin D, and zinc, were not associated with a mortality benefit in COVID-19. Vitamin D may be associated with lower intubation rate and shorter LOS, but vitamin C did not reduce intubation rate or LOS. Further research is needed to validate our findings.

Effect of Prone Positioning on Clinical Outcomes of Non-Intubated Subjects With COVID-19.

BACKGROUND: Awake prone positioning (APP) has been recently proposed as an adjunctive treatment for non-intubated coronavirus disease 2019 (COVID-19) patients requiring oxygen therapy to improve oxygenation and reduce the risk of intubation. However, the magnitude of the effect of APP on clinical outcomes in these patients remains uncertain. We performed a comparative systematic review and meta-analysis to evaluate the effectiveness of APP to improve the clinical outcomes in non-intubated subjects with COVID-19. METHODS: The primary outcomes were the need for endotracheal intubation and mortality. The secondary outcome was hospital length of stay. Pooled risk ratio (RR) and mean difference with the corresponding 95% CI were obtained by the Mantel-Haenszel method within a random-effect model. RESULTS: A total of 14 studies (5 randomized controlled trials [RCTs] and 9 observational studies) involving 3,324 subjects (1,495 received APP and 1,829 did not) were included. There was a significant reduction in the mortality rate in APP group compared to control (RR 0.68 [95% CI 0.51-0.90]; P = .008, I2 = 52%) with no significant effect on intubation (RR 0.85 [95% CI 0.66-1.08]; P = .17, I2 = 63%) or hospital length of stay (mean difference -3.09 d [95% CI-10.14-3.96]; P = .39, I2 = 97%). Subgroup analysis of RCTs showed significant reduction in intubation rate (RR 0.83 [95% CI 0.72-0.97]; P = .02, I2 = 0%). CONCLUSIONS: APP has the potential to reduce the in-hospital mortality rate in COVID-19 subjects with hypoxemia without a significant effect on the need for intubation or length of hospital stay. However, there was a significant decrease in the need for intubation on subgroup analysis of RCTs. More large-scale trials with a standardized protocol for prone positioning are needed to better evaluate its effectiveness in this select population.

Dental health status and hygiene in children with cerebral palsy: A matched case-control study.

BACKGROUND: Children with cerebral palsy (CP) are at risk for oral pathology and parafunctional habits, and are reliant on caregivers for oral hygiene. AIM: To evaluate oral hygiene habits and oral examination findings among a group of children with CP and a healthy age- and gender-matched control group. DESIGN: A comparative, cross-sectional study, consisting of a questionnaire component and a standard dental examination component, each applied to both groups. RESULTS: Eighty-three children with CP and 84 healthy children were included. Parents of children with CP were more likely to be of low educational level and lack a professional line of occupation (P < .05). Children with CP were less likely to be responsible for oral hygiene maintenance, adhere to toothbrushing, or receive procedural dental care (P < .001). Food packing and drooling were significantly more likely in children with CP. Malocclusion type III was more prevalent among children with CP, as was higher gingival index and gingival enlargement index-horizontal component (P < .001). There were no differences in caries experience between the CP and control groups. CONCLUSIONS: Children with CP have suboptimal oral hygiene habits, limited access to procedural dental care, higher parafunctional habits, and increased periodontal pathology.

Associations between supportive and undermining coparenting and controlling feeding practices.

Parents play an important role in shaping child eating and weight outcomes through feeding practices. Controlling feeding practices are positively related to child obesogenic eating and obesity risk. Although many parents' characteristics have been examined in relation to controlling feeding practices, less is known about the role of coparenting. The current study seeks to examine whether coparenting (supportive versus undermining) predict controlling feeding practices (use of food for emotion regulation, food as a reward, pressure to eat, restriction for health, restriction for weight). A total of 160 parents (56% females) of preschool-aged children between 3- and 5-years old completed an online survey. After accounting for parent characteristics (i.e., sex, BMI, age), regression analyses showed that supportive coparenting was not predictive of controlling feeding practices. However, regression analyses showed that undermining coparenting predicted greater use of food for emotion regulation, food as a reward, and restriction for weight, but was not predictive of pressure to eat and restriction for health. Implications associated with these findings are discussed.
