Published: May 2022

Los nódulos tiroideos son causa frecuente de consulta y preocupación entre los pacientes, el uso generalizado de estudios de imagen ha provocado un aumento en la incidencia de esta entidad, a pesar de su bajo riesgo de malignidad significa un reto diagnóstico detectar los nódulos potencialmente malignos, para ello, se realiza una anamnesis y examen físico orientados dirigidos a detectar factores de riesgo en la historia personal y familiar, además de signos físicos sugestivos de un proceso infiltrativo. Dentro del abordaje inicial está indicada la medición de niveles séricos de tirotropina (TSH) y ultrasonido de tiroides, asimismo, se cuenta con otros estudios diagnósticos como la gammagrafía, la citología y las pruebas moleculares que ayudan a determinar la funcionalidad y la naturaleza del nódulo. El tratamiento de los nódulos puede ser médico o quirúrgico, mientras que algunos solo requieren observación en el tiempo. La alta prevalencia de nódulos tiroideos requiere estrategias costo efectivas y basadas en evidencia para realizar la estratificación de riesgo, diagnóstico, tratamiento y seguimiento de esta patología.

Focal lesionectomy as surgical treatment of epilepsy in patients with Sturge-Weber syndrome: a case-based systematic review and meta-analysis
Authors: Frank Nicole Alexandra , Greuter Ladina , Dill Patricia Elsa , Guzman Raphael , Soleman Jehuda 
Published: May 2022

OBJECTIVE
Sturge-Weber syndrome (SWS) is a rare neurocutaneous disorder presenting mostly with a facial port-wine stain and leptomeningeal angiomatosis. More than 85% of the patients are affected by epilepsy by the age of 2 years. Seizure and symptom control is the focus of SWS treatment, since no causal therapy exists yet. For pharmacologically intractable epilepsy, surgery is a treatment option. The aim of this systematic review and meta-analysis was to provide an overview of the literature regarding lesionectomy in SWS with a focus on seizure outcome, complications, and motor and cognitive development.

METHODS
The PubMed and Embase databases were searched using a systematic search strategy to identify studies on SWS from their inception until 2021. Two independent researchers assessed the studies for inclusion and quality. Outcome measures were seizure outcome, postoperative complications, and motor and cognitive development. Thereafter, a systematic review was conducted, and a meta-analysis was performed for all included cohort studies. Risk of bias was assessed using the Newcastle-Ottawa Scale. Forest plots have been generated for all outcomes; risk ratio was used for pooled outcomes. A p value < 0.05 was considered as statistically significant.

RESULTS
After removal of duplicates, the authors screened 439 articles, of which 9 articles with 150 patients were included. Our case and 5 case reports and 4 retrospective cohort studies were included for systematic review. The latter 4 studies qualified for the meta-analysis. In these 4 articles, 144 patients received surgical treatment: 81 (56%) underwent focal lesionectomy and 63 (44%) hemispherectomy. Pooled outcome analysis for postoperative favorable seizure outcome showed a nonsignificant difference between lesionectomy and hemispherectomy (69.2% vs 87.3%; RR 0.73, 95% CI 0.50–1.08; t = −2.56, p = 0.08). Lesionectomy showed a significantly lower rate for developmental delay and postoperative hemiparesis in comparison with hemispherectomy (29.8% vs 76.3%; RR 0.41, 95% CI 0.28–0.59; z = −4.77, p < 0.0001 and 18.1% vs 100%; RR 0.11, 95% CI 0.06–0.21; z = −6.58, p < 0.0001, respectively).

CONCLUSIONS
Based on the limited literature available, lesionectomy leads to a nonsignificant lower seizure control rate, while postoperative developmental or motor deficits are significantly lower compared with hemispherectomy. Therefore, focal lesionectomy remains a valid alternative to hemispherectomy in SWS with a clearly localized epileptogenic area; however, individual case-based decisions in a specialized multidisciplinary team are of paramount importance.

Published: May 2022

OBJECTIVE
Neurofibromatosis type 1 (NF1) dystrophic scoliosis is an early-onset, rapidly progressive multiplanar deformity. There are few studies on the surgical management of this patient population. Specifically, perioperative morbidity, instrument-related complications, and quality-of-life outcomes associated with surgical management have not been systematically evaluated. In this study, the authors aimed to perform a systematic review on the natural history, management options, and surgical outcomes in patients who underwent NF1 dystrophic scoliosis surgery.

METHODS
A PubMed search for articles with “neurofibromatosis” and either “dystrophic” or “scoliosis” in the title or abstract was performed. Articles with 10 or more patients undergoing surgery for NF1 dystrophic scoliosis were included. Data regarding indications, treatment details, morbidity, and outcomes were summarized and analyzed with descriptive statistics.

RESULTS
A total of 310 articles were identified, 48 of which were selected for full-text review; 30 studies describing 761 patients met the inclusion criteria. The mean age ranged from 7 to 22 years, and 99.7% of patients were younger than 18 years. The mean preoperative coronal Cobb angle was 75.2°, and the average correction achieved was 40.3°. The mean clinical follow-up in each study was at least 2 years (range 2.2–19 years). All patients underwent surgery with the intent of deformity correction. The scoliosis regions addressed were thoracic curves (69.6%) and thoracolumbar (11.1%) and lumbar (14.3%) regions. The authors reported on a variety of approaches: posterior-only, combined anterior-posterior, and growth-friendly surgery. For fixation techniques, 42.5% of patients were treated with hybrid constructs, 51.5% with pedicle screw–only constructs, and 6.0% with hook-based constructs. Only 0.9% of patients underwent a vertebral column resection. The nonneurological complication rate was 14.0%, primarily dural tears and wound infections. The immediate postoperative neurological deficit rate was 2.1%, and the permanent neurological deficit rate was 1.2%. Ultimately, 21.5% required revision surgery, most commonly for implant-related complications. Loss of correction in both the sagittal and coronal planes commonly occurred at follow-up. Five papers supplied validated patient-reported outcome measures, showing improvement in the mental health, self-image, and activity domains.

CONCLUSIONS
Data on the surgical outcomes of dystrophic scoliosis correction are heterogeneous and sparse. The perioperative complication rate appears to be high, although reported rates of neurological deficits appear to be lower than clinically observed and may be underreported. The incidence of implant-related failures requiring revision surgery is high. There is a great need for multicenter prospective studies of this complex type of deformity.

The Stabilizing Effect of Li4Ti5O12 Coating on Li1.1Ni0.35Mn0.55O2 Cathode for Liquid and Solid–State Lithium-Metal Batteries
Authors: Hu Wei , Zhong Shengwen , Rao Xianfa , Yan Tingting , Zeng Min 
Published: May 2022

Li–rich layered cathode materials with high energy density suffer from severe capacity decay during cycling, which is associated with volume change and electrolyte corrosion during (de)lithiation. A Li+ ionic conducting Li4Ti5O12 coating with high structural integrity is developed on Li1.1Ni0.35Mn0.55O2 cathodes via a dry powder coating method. The electrochemical performances of Li4Ti5O12–coated Li1.1Ni0.35Mn0.55O2 cathodes in liquid and solid–state lithium batteries were investigated. The initial discharge capacity of Li4Ti5O12–coated Li1.1Ni0.35Mn0.55O2 in the liquid electrolyte has been improved from 116.5 mA h g−1 to 123.7 mA h g−1 at 0.1°C. An impressive cyclability with a high capacity retention of 89.3% was achieved in solid–state lithium batteries. These results demonstrate that the Li4Ti5O12 coating plays an essential role in enhancing the specific capacity and better performance for Li1.1Ni0.35Mn0.55O2 cathode.

ObjectiveIn the current study, we aimed to assess resistin mRNA levels in the peripheral blood mononuclear cells (PBMCs) of dermatomyositis patients with interstitial lung disease (DM-ILD) and their correlation with disease activity.MethodsWe detected resistin mRNA levels in the PBMCs of 37 DM-ILD, 8 DM patients without ILD, and 19 healthy control (HC) subjects by performing quantitative reverse transcription real-time polymerase chain reaction analysis. Associations between resistin expression levels and major clinical manifestations, laboratory examinations, and disease activity were also analyzed. In addition, resistin expression in lung specimens from patients with DM-ILD was examined via immunohistochemistry and immunofluorescence.ResultsResistin mRNA levels in PBMCs were significantly higher in DM-ILD than that in DM patients without ILD and HCs (p = 0.043, 0.014, respectively). Among these DM-ILD patients, the resistin levels were significantly elevated in those with rapidly progressive ILD than in those with chronic ILD (p = 0.012). The resistin mRNA levels in DM-ILD positively correlated with serum alanine aminotransferase (r = 0.476, p = 0.003), aspartate aminotransferase (r = 0.488, p = 0.002), lactate dehydrogenase (r = 0.397, p = 0.014), C-reactive protein (r = 0.423, p = 0.008), ferritin (r = 0.468, p = 0.003), carcinoembryonic antigen (r = 0.416, p = 0.011), carbohydrate antigen 125 (r = 0.332, p = 0.047), interleukin-18 (r = 0.600, p &lt; 0.001), and lung visual analog scale values (r = 0.326, p = 0.048), but negatively correlated with the diffusing capacity of carbon monoxide (DLco)% (r = −0.447, p = 0.041). Immunohistochemical analysis of resistin showed its elevated expression in the macrophages, alveolar epithelial cells, and weak fibrotic lesions from patients with DM-ILD. Immunofluorescence staining confirmed CD68+ macrophages co-express resistin.ConclusionsResistin levels were increased in patients with DM-ILD and associated with disease activity and ILD severity. Therefore, resistin may participate in the pathogenesis of DM-ILD and may act as a useful biomarker.

Published: May 2022

BackgroundThe reliability and validity of recalled body shape were unknown in China. This study was conducted to examine the reliability and validity of recalled body shape as well as the responsiveness of obesity classification by recalled body shape among the Chinese rural population.MethodsA total of 166 people from the Henan rural cohort were enrolled. The Spearman's correlation coefficient (SCC), intraclass correlation coefficient (ICC), and Cronbach's α were calculated to assess the reliability and validity of recalled body shape. Additionally, the receiver operator characteristic curve (ROC) was performed to assess the responsiveness.ResultsThe SCC between the twice recalled body shape ranged from 0.383 to 0.578, and the ICC ranged from 0.357 to 0.615. Besides, the Cronbach's α of the recalled body shape questionnaire was 0.845. At the age of 20–70, the SCC between recalled body shape and actual body mass index (BMI) and waist circumference (WC) ranged from 0.563 to 0.699 and 0.409 to 0.661, respectively. Furthermore, above the age of 20, the area under the curve (AUC) of classifying general obesity and abdominal obesity by recalled body shape ranged from 0.833 to 0.960 and 0.686 to 0.870, respectively.ConclusionThe results indicated that recalled body shape had moderate reliability, validity, and discriminative degree for earlier obesity among the Chinese rural population.
The Association between Maternal Periodontitis and Preterm Birth: A Case-Control Study in a Low-Resource Setting in Sudan, Africa
Authors: Shaggag Lubna M. , ALhabardi Nadiah , Adam Ishag 
Published: May 2022

Background and Objectives: Vast data have been published recently on the association between periodontitis and preterm birth (PB). However, these studies have shown inconsistent results. Few of them were conducted in Africa, and data has not been published on the association between periodontitis and PB in Sudan. Materials and Methods: A case-control study was conducted at the Omdurman maternity hospital in Sudan from February through October 2021. The cases were women with spontaneous PB (<37 weeks), and healthy women with TB (37–42 weeks) were the controls. Questionnaires (demographics, medical and obstetric factors) were completed through face-to-face interviews. Periodontitis was diagnosed by the Community Periodontal Index as: “bleeding on probing and a pocket depth of ≥3 mm and clinical attachment loss of ≥6 mm, calculus with plaque deposits, and gingival recession”. Multivariate regression analysis was performed with PB as the dependent variable. Results: One hundred sixty-five women were enrolled in each arm of the study. The age, parity and body mass index did not significantly differ between the women with PB and those with TB. Compared with the controls, a significantly higher number of women with PB had periodontitis (50/165 (30.3%) vs. 30/165 (18.2%), p = 0.011). The association between periodontitis and PB was significant. Women who had periodontitis had double the odds of having PB compared to women who had no periodontitis (adjusted Odd Ratio = 2.05, 95% Confidence Interval = 1.20–3.52). Moreover, the haemoglobin level (adjusted Odd Ratio = 0.67, 95% Confidence Interval = 0.51–0.88) was inversely associated with PB. Conclusion: The study results indicate that periodontitis and low haemoglobin were strongly associated with PB. Preventive measures, including the use of periodontitis screening and the prevention of anaemia, are needed to reduce PB in this setting.
