Tidal dissipation in rotating low-mass stars and implications for the orbital evolution of close-in massive planets
Authors: Bolmont E. , Gallet F. , Mathis S. , Charbonnel C. , Amard L. , Alibert Y.
Published: June 2017

Observations of hot-Jupiter exoplanets suggest that their orbital period distribution depends on the metallicity of the host stars. We investigate here whether the impact of the stellar metallicity on the evolution of the tidal dissipation inside the convective envelope of rotating stars and its resulting effect on the planetary migration might be a possible explanation for this observed statistical trend. We use a frequency-averaged tidal dissipation formalism coupled to an orbital evolution code and to rotating stellar evolution models in order to estimate the effect of a change of stellar metallicity on the evolution of close-in planets. We consider here two different stellar masses: 0.4 M⊙ and 1.0 M⊙ evolving from the early pre-main sequence phase up to the red-giant branch. We show that the metallicity of a star has a strong effect on the stellar parameters, which in turn strongly influence the tidal dissipation in the convective region. While on the pre-main sequence, the dissipation of a metal-poor Sun-like star is higher than the dissipation of a metal-rich Sun-like star; on the main sequence it is the opposite. However, for the 0.4 M⊙ star, the dependence of the dissipation with metallicity is much less visible. Using an orbital evolution model, we show that changing the metallicity leads to different orbital evolutions (e.g., planets migrate farther out from an initially fast-rotating metal-rich star). Using this model, we qualitatively reproduced the observational trends of the population of hot Jupiters with the metallicity of their host stars. However, more steps are needed to improve our model to try to quantitatively fit our results to the observations. Specifically, we need to improve the treatment of the rotation evolution in the orbital evolution model, and ultimately we need to consistently couple the orbital model to the stellar evolution model.
Indocyanine Green Fluorescence to Evaluate Nasoseptal Flap Viability in Endoscopic Endonasal Cranial Base Surgery
Authors: Kerr Edward , Jamshidi Ali , Carrau Ricardo , Campbell Raewyn , Filho Leo , Otto Bradley , Prevedello Daniel
Published: June 2017

Objectives The pedicled nasoseptal flap (NSF) has dramatically reduced postoperative cerebrospinal fluid leakage following endoscopic endonasal approach (EEA) surgery. Although rare, its arterial supply may be damaged during harvest or may be preoperatively damaged for numerous reasons. Early recognition permits harvesting a contralateral flap before sacrificing its pedicle as part of the surgical exposure or use of an alternative flap.

Design Technical feasibility study and case series.

Setting Tertiary care university-associated medical center.

Participants Five patients requiring an EEA with NSF reconstruction.

Main Outcome Measures During NSF harvest, intravenous indocyanine green (IVICG) was administered, and a customized endoscopic system was used to visualize the emerging fluorescence. At the end of each case, just before final positioning of the NSF, additional IVICG was administered, and the custom endoscope was again introduced to evaluate fluorescence.

Results In four patients, the entire NSF fluoresced brightly with IVICG on initial harvest and before final positioning. One patient showed heterogeneous fluorescence of the pedicle and distal parts of the NSF at both stages. All NSFs healed well without complication.

Conclusion IVICG facilitates real-time evaluation NSF's arterial supply. This may provide early recognition of arterial compromise, allowing the harvest of alternate flaps or modification of surgery.

Authors: Risteski Petar , Miskovic Aleksandra , Moritz Anton , Zierer Andreas , Monsefi Nadejda
Published: June 2017

Background The David procedure is a well-known technique in selected patients with aortic root pathology. A minimally invasive approach in heart surgery increases open interest.

Methods From 1991 to 2015, the David technique was performed in 296 patients in our unit. In 90 cases, operations were performed through partial upper sternotomy. The patient mean age was 57 ± 14 years in the minimally invasive group (n = 90) and 58 ± 14 years in the complete sternotomy group (n = 206; p = 0.2). The neosinus modification was performed in 80 patients (89%) in the minimally invasive group and in 79 patients (38%) in the complete sternotomy group (p < 0.01). Mean follow-up was 3 ± 2 years in the minimally invasive group and 8 ± 4 years in the complete sternotomy group.

Results Thirty-day mortality was zero in the minimally invasive group and was 3% (n = 6) in the complete sternotomy group (p = 0.1). The need for packed red blood cells was significantly lower in the minimally invasive group (1.6 ± 3 U) than in the complete sternotomy group (3.7 ± 6 U; p < 0.01). Thirty late deaths (2% per patient-year) were observed in the complete sternotomy group versus zero in the minimally invasive group (p < 0.01). One patient (0.5% per patient-year) in the minimally invasive group and 12 patients (0.8% per patient-year) in the complete sternotomy group required reoperation in the follow-up period (p = 0.05).

Conclusions Minimally invasive David technique for patients with ascending aortic aneurysm and aortic valve insufficiency offers a good solution with low perioperative blood transfusion rate. Our midterm results show low valve-related complications and reoperation rate. However, long-term follow-up of the minimally invasive group is necessary.

Glucose transporter 1 (GLUT1) deficiency syndrome (GLUT1DS) is a disorder resulting from shortage of energy in the brain caused by reduced GLUT1 activity. Its common clinical symptoms include seizures, microcephaly, intellectual disability, abnormal ocular movements, ataxia, and dystonia. We report a case of GLUT1DS with unusual symptoms, including periventricular calcification. The patient is a Japanese girl, whose seizures had always evolved into status epilepticus since she was 4 months old. She also had cataracts and horizontal nystagmus. Neuroimaging studies showed periventricular calcification and brain atrophy. Laboratory data revealed pseudohyperkalemia, reticulocyte increase, and hypoglycorrhachia. A mutation of c1306_1308delATC (p.Ile436del) was identified in the SLC2A1 gene, and she was thus diagnosed with GLUT1DS. A case with the identical SLC2A1 gene mutation and similar clinical findings was previously reported by Bawazir et al (2012). The leak of monovalent cations through the red cell membrane causes hemolysis in such patients, and a similar phenomenon may occur at the blood–brain barrier and the lens epithelium. After commencing ketogenic diet therapy, the electroencephalogram (EEG) abnormalities improved markedly and the patient's development advanced. Clinicians should be aware of atypical GLUT1DS.
Liver Imaging Reporting and Data System Classification of Hepatocellular Carcinoma: Implications for Clinical Management
Authors: Borofsky Samuel , Karajgikar Jay , Roth Christopher , Deshmukh Sandeep
Published: June 2017

As the incidence of hepatocellular carcinoma (HCC) continues to increase worldwide, the role imaging plays in management continues to gain clinical importance. Multiple entry points exist for patients in the scheme of diagnosis and treatment of HCC and non-HCC malignancies. Further complicating this scheme is the lack of standardization in the language used for diagnostic imaging and management recommendations. The Liver Imaging Reporting and Data System (LI-RADS) was created to improve communication between clinicians and management teams. LI-RADS serves to standardize reports, improving physician satisfaction and aiding in management decisions across the continuum of care of these patients. Furthermore, LI-RADS provides technical specifications across multiple imaging modalities for screening and follow-up examinations, with the end goal of curing the disease or prolonging survival. In this review, the LI-RADS algorithm will be expanded upon, as well as its utility for various treatment options using the standardized LI-RADS lexicon. Additionally, pitfalls and non-HCC malignancies will also be addressed with resultant improvement in reproducibility of radiology reports that guide therapeutic management.
Genetics of Hepatocellular Carcinoma: Risk Stratification, Clinical Outcome, and Implications for Therapy

Published: June 2017

Hepatocellular carcinoma (HCC), the most common form of primary liver cancer, is a highly heterogeneous disease with a dismal prognosis. During the last decade, significant efforts to elucidate the genetic background of HCC have led to the identification of the major genomic aberrations driving the disease. Nonetheless, only few of them (∼30%) are currently amenable for treatment. Two clear-cut gene expression based HCC molecular classes, namely “proliferation” and “nonproliferation,” have been described. The “proliferation” class is characterized by enrichment in poor prognostic signatures, a more aggressive phenotype, and poorer outcome. In addition, exposure-specific mutational patterns have been identified (smoking, alcohol, aflatoxin B, etc.), whereas molecular signatures from the surrounding cirrhotic liver and single nucleotide polymorphisms have been linked with HCC occurrence. Despite such advances, no molecular biomarker has yet been incorporated in clinical decision-making. In this review, the authors summarize the most recent molecular findings in HCC pointing toward prospects for translating this knowledge into specific clinical interventions.

Published: June 2017

Background Pleuroperitoneal communication is a serious complication in patients receiving continuous ambulatory peritoneal dialysis. However, few single-institutional reports discuss the details of pleuroperitoneal communication in continuous ambulatory peritoneal dialysis patients regarding the intraoperative findings, postoperative course, and outcomes.

Methods We retrospectively reviewed the records of consecutive pleuroperitoneal communication patients who were treated surgically from September 2008 to March 2016.

Results All four patients had right-sided hydrothorax. The time from introduction of continuous ambulatory peritoneal dialysis to the diagnosis of hydrothorax ranged from 1 to 12 months (average: 5.5 months). Case 1 and case 4 had bleblike lesions near the center of the diaphragm; case 2 had a small hole located near the cardiophrenic angle, and case 3 had thinning of the diaphragm near the cardiophrenic angle. All lesions except for case 3 were directly closed with absorbable suture and reinforced by fibrin glue and a polyglycolic acid sheet. In case 3, the thinned diaphragm was reinforced using fibrin glue, a sealing sheet, and pericardial fat pad tissue. Continuous ambulatory peritoneal dialysis was reinitiated an average period of 11 days (range: 4–15 days) postoperatively. During postoperative follow-up, there was no recurrence of hydrothorax. Continuous ambulatory peritoneal dialysis was continued for an average of 16.7 months (range: 3–34 months) after surgical treatment.

Conclusions Surgical treatment for pleuroperitoneal communication is a safe and acceptable procedure and could greatly benefit continuous ambulatory peritoneal dialysis patients.

Published: June 2017

Persistent air leaks (PALs) are regarded as a frequent complication after thoracic surgery resulting in prolonged hospitalization and increased morbidity. Several more or less invasive therapeutic approaches are available for treatment of PAL with varying degrees of success. The endoscopic placement of one-way intrabronchial valves in the segment(s) in which the air leak has been located offers a highly effective and well-tolerated minimal invasive option for patients with PAL.
