Study design Retrospective study. Objective To analyze the relationships between three-dimensional (3D) measurements of spinal deformity and Scoliosis Research Society-22 (SRS-22) scores in preoperative patients with major thoracic adolescent idiopathic scoliosis (AIS). Previous studies reported 2D measurements were not or only weakly correlated with preoperative SRS-22 scores. However, 2D measures do not always accurately represent the 3D deformity. Methods A multicenter prospective registry of surgically treated AIS patients was reviewed for patients with right major thoracic AIS (Lenke type 1-4) who underwent biplanar radiography and completed the SRS-22 questionnaire preoperatively. For the 3D measurements, two reference frames were utilized global (gravity/patient-based) and local (vertebra/disc-based). To obtain regional measurements, the individual segments in the appropriate reference plane were summed between the levels of interest. Patients were divided into two groups for each SRS-22 domain accordited. Level of evidence II, prognostic.Study design Retrospective. Objectives Utilize three-dimensional (3D) measurements to assess the relationship between thoracic scoliosis severity and thoracic kyphosis in a large, multicenter cohort, and determine impact of 3D measurements on adolescent idiopathic scoliosis (AIS) curve classification. Research has demonstrated differences in two-dimensional (2D) and 3D assessment of the sagittal plane deformity in AIS. A prior smaller, single-institution study demonstrated an association between scoliosis severity and loss of 3D thoracic kyphosis. Methods Data included retrospective compilation of prospectively enrolled bracing candidates and prospectively enrolled surgical candidates with thoracic AIS. Analysis included two groups based on thoracic curve magnitude moderate (20-45°) and severe (> 45°). Imaging was performed using 2D radiographs. 3D thoracic kyphosis was calculated using a 2D to 3D conversion formula. Kyphosis was categorized according to the Lenke classification sagittal plane modifier. Resuloved with a 2D-3D conversion formula. Findings indicate potential for classification system improvement with use of 3D sagittal plane measurements. Level of evidence IV.A recent article by Corburn et al. lays out the policies that would help slum communities in the global south deal with COVID-19. That article notes the vulnerabilities of people in these informal settlements and argues that any assistance program must recognize these realities so that the policies do not further jeopardize the survival of large segments of the population of these communities. https://www.selleckchem.com/products/filgotinib.html This note extends the arguments in that paper, focusing on some of the logistic issues involved in providing assistance to informal settlements. It argues that such assistance is essential not only for the help it would provide to people in these settlements but also because the residents of these communities should be key targets of assistance. Because of the location and occupation of most of the residents of these communities, targeting them simultaneously addresses health and economy-wide concerns generated by COVID-19. Their characteristics make them much more likely to be afflicted by the virus and spread it to others. The main conclusions of this note with respect to policy are that the scale of such assistance is likely to be larger than has so far been proposed, that in countries with limited testing ability slums provide one of the most effective places to target assistance, that the role of community groups in providing the assistance is difficult to exaggerate, and that philanthropy has a role to play in supporting innovation.Backgound Bartter's syndrome (BS) is a rare group of salt losing tubulopathies due to the impairment of transport mechanisms at the thick ascending limb of the Henle's loop. Data sources Literature reviews and original research articles were collected from database, including PubMed and Scopus. Results According to the time of onset and symptoms, BS can be classified into antenatal and classic BS. Molecular studies have identified different subtypes of BS. BS types I, II and III are caused by mutations on genes encoding the luminal Na+-K+-2Cl- co-transporter, the luminal K+ channel ROMK, and the basolateral chloride channel ClC-Kb (CLCNKB), respectively. Loss-of-function mutations of Barttin CLCNK type accessory beta subunit cause BS type IVa. Simultaneous mutations of CLCNKB and CLCNKA cause BS type IVb. BS type V consists in a novel transient form characterized by antenatal presentation due to mutations in the MAGE family member D2. Severe gain-of-function mutations of the extracellular calcium sensing receptor gene can result in an autosomal dominant condition of BS. Main clinical and biochemical alterations in BS include polyuria, dehydration, hypokalemia, hypochloremic metabolic alkalosis, hyperreninemia, high levels of prostaglandins, normal or low blood pressure, hypercalciuria and failure to thrive. Treatment focuses mainly at correcting dehydration and electrolyte disturbances and in measures to reduce polyuria, including the use of nonsteroidal anti-inflammatory medications to control excessive renal prostaglandin E2 production. Conclusions Early diagnosis and treatment of BS may prevent long-term consequences such as growth failure, nephrocalcinosis and end-stage renal disease.Hyaluronic acid (HA) is widely used to treat various ocular diseases like dry eye syndrome, keratoconus, and other corneal epithelial injuries. The currently available eye drop solutions need frequent doses affecting the routine life style of patients. In this work, the silicone contact lens was designed to entrap HA and Pluronic®F127 to improve the wettability of the contact lens to treat various ocular diseases. The soaking method (HA-SM) was compared with the direct entrapment (DL-HA-PI) technique. The HA-Pluronic®F127-laden contact lenses (DL-HA-PI) showed acceptable optical transmittance with improved swelling (water content) properties. The in vitro release data showed high burst release with HA-SM contact lenses (12-36 h), while DL-HA-PI contact lenses showed prolong release up to 96 h. The in vivo release in the rabbit tear fluid showed high HA concentration (tear fluid) with DL-HA-PI contact lenses in comparison to the HA-SM contact lenses. The DL-HA-PI-3 batch with Pluronic®F127 showed more promising results in schirmer strip study in comparison to DL-HA-3 batch (without Pluronic®F127). The presence of Pluronic®F127 with HA showed high potential to improve hydration property of the contact lens. The corneal healing model showed reduction in the ocular inflammatory symptoms with DL-HA-PI-3 batch, thus demonstrating the potential of HA and Pluronic®F127 to be used in various ocular diseases.Background Survival rates among childhood cancer survivors (CCSs) have significantly risen in the last 40 years due to substantial improvements in treatment protocols. However, this improvement has brought with it serious late effects that frequently involve the endocrine system. Of the endocrine disorders, GH deficiency (GHD) is the most common among CCSs as a consequence of a history of cancers, surgery, and/or radiotherapy involving the hypothalamo-pituitary region. Methods A comprehensive search of English language articles regardless of age was conducted in the MEDLINE database between December 2018 and October 2019. We selected all studies on GH therapy in CCSs during the transition age regarding the most challenging topics when to retest; which diagnostic tests and cut-offs to use; when to start GH replacement therapy (GHRT); what GH dose to use; safety; quality of life, compliance and adherence to GHRT; interactions between GH and other hormonal replacement treatments. Results In the present review, we provide an overview of the current clinical management of challenges in GHD in cancer survivors in the transition age. Conclusions Endocrine dysfunction among CCSs has a high prevalence in the transition age and increase with time. Many endocrine disorders, including GHD, are often not diagnosed or under-diagnosed, probably due to the lack of specialized centers for the long-term follow-up. Therefore, it is crucial that transition specialized clinics should be increased in terms of number and specific skills in order to manage endocrine disorders in adolescence, a delicate and complex period of life. A multidisciplinary approach, also including psychological counseling, is essential in the follow-up and management of these patients in order to minimize their disabilities and maximize their quality of life.Purpose Hyponatremia after pituitary surgery is a frequent finding with potential severe complications and the most common cause for readmission. Several studies have found parameters associated with postoperative hyponatremia, but no reliable specific predictor was described yet. This pilot study evaluates the feasibility of machine learning (ML) algorithms to predict postoperative hyponatremia after resection of pituitary lesions. Methods Retrospective screening of a prospective registry of patients who underwent transsphenoidal surgery for pituitary lesions. Hyponatremia within 30 days after surgery was the primary outcome. Several pre- and intraoperative clinical, procedural and laboratory features were selected to train different ML algorithms. Trained models were compared using common performance metrics. Final model was internally validated on the testing dataset. Results From 207 patients included in the study, 44 (22%) showed a hyponatremia within 30 days postoperatively. Hyponatremic measurements peaked directly postoperatively (day 0-1) and around day 7. Bootstrapped performance metrics of different trained ML-models showed largest area under the receiver operating characteristic curve (AUROC) for the boosted generalized linear model (67.1%), followed by the Naïve Bayes classifier (64.6%). The discriminative capability of the final model was assessed by predicting on unseen dataset. Large AUROC (84.3%; 67.0-96.4), sensitivity (81.8%) and specificity (77.5%) with an overall accuracy of 78.4% (66.7-88.2) was reached. Conclusion Our trained ML-model was able to learn the complex risk factor interactions and showed a high discriminative capability on unseen patient data. In conclusion, ML-methods can predict postoperative hyponatremia and thus potentially reduce morbidity and improve patient safety.Background It is unclear how the CHA2DS2-VASc score can predict subsequent chronic kidney disease (CKD) and end-stage renal disease (ESRD) among atrial fibrillation (AF) patients. Methods We identified incident AF patients without CKD between 2000 and 2013 from the National Health Insurance Research Database (NHIRD) of Taiwan and calculated the CHA2DS2-VASc score for each patient. Adjusted hazard ratio (HR) with 95% confidence interval (CI) was estimated from multivariate cause-specific Cox models to assess the risk of CKD and ESRD associated with the CHA2DS2-VASc score. Results A total of 8764 participants with AF who did not have CKD were included in the analysis. The mean age was 69.63 ± 13.48 years and 4800 (54.8%) were males. The adjusted HR of CKD displayed a stepwise increase with the increase in the CHA2DS2-VASc score. When compared with those with a CHA2DS2-VASc score of 0, the adjusted HRs of CKD were 1.57 (95% CI 1.09-2.26), 2.04 (95% CI 1.42-2.94), 2.48 (95% CI 1.70-3.62), 2.88 (95% CI 1.95-4.26), 3.
