Clinical Manifestations of Acute COVID-19 in Previously Healthy Pediatric Patients Diagnosed by Rapid Antigen Screening in a Community-Based, Outpatient Primary Care Pediatrics Practice.

Background: The PediCenter and Niles Children's Clinic provide pediatric primary and urgent care services in central California. We remained open throughout the COVID-19 pandemic, providing scheduled well child-care and sick visits.

Methods: Beginning in September 2020, we implemented a COVID-19 screening program.

Crystal and Electronic Structures of ANaIO Periodate Double Perovskites (A = Sr, Ca, Ba): Candidate Wasteforms for I-129 Immobilization.

The synthesis, structure, and thermal stability of the periodate double perovskites ANaIO (A= Ba, Sr, Ca) were investigated in the context of potential application for the immobilization of radioiodine. A combination of X-ray diffraction and neutron diffraction, Raman spectroscopy, and DFT simulations were applied to determine accurate crystal structures of these compounds and understand their relative stability. The compounds were found to exhibit rock-salt ordering of Na and I on the perovskite B-site; BaNaIO was found to adopt the 3 aristotype structure, whereas SrNaIO and CaNaIO adopt the 2/ hettotype structure, characterized by cooperative octahedral tilting.

The history behind successful uterine transplantation in humans.

This paper aimed to describe the basic aspects of uterine transplant (UTx) research in humans, including preliminary experiences in rodents and domestic species. Studies in rats, domestic species, and non-human primates validated and optimized the UTx procedure in terms of its surgical aspects, immunosuppression, rejection diagnosis, peculiarities of pregnancy in immunosuppressed patients, and patients with special uterine conditions. In animal species, the first live birth from UTx was achieved in a syngeneic mouse model in 2003.

[Pancreatico-jejunostomy in defunctionalized Roux-Y loop. An alternative for low volume hospitals].

This case is about a one obesity patient to carry out pancreaticoduodenectomy for solido pseudopapilary cyst of the pancreatic head, considerate in pancreatic surgery like high risk for to present soft pancreatic, wirsung smaller to 2mm and not bile duct dilatation .The pancreaticojejunostomy was performed end to end with invagination of the pancreatic stump with suture in tobacco bag to a defunctionalized jejunal loop Y the Roux to avoid middle alkali of the bile duct - jejunostomy.

Brain injury severity, litigation status, and self-report of postconcussive symptoms.

The Postconcussive Symptom Questionnaire (PCSQ) was developed to assess the symptoms associated with the controversial diagnosis of postconcussion syndrome. We examined item endorsement on the PCSQ in two groups. The first group was made up of individuals diagnosed with moderate to severe traumatic brain injury.

Ten-year survival and cost following breast cancer recurrence: estimates from SEER-medicare data.

Objective: A variety of pharmacologic therapies are available or in development for the prevention of breast cancer recurrence. Assessing the value of these treatments is compromised by a paucity of data on the impact of recurrence on economic costs and survival. The purpose of this study was to shed light on these issues.

[Morbidity and mortality rates in relation to the "surgeon factor" after duodenopancreatectomy].

Objectives: The present study was designed to determine whether the surgeon factor has an independent effect on morbidity and mortality rates after duodenopancreatectomy.

Material And Method: Between October 2002 and December 2006, we performed a study of 119 patients who underwent duodenopancreatectomy. The surgeons were divided into 3 groups according to the number of interventions they performed each year: a low volume group (three Whipple procedures per year), a medium volume group (four to 10 Whipple procedures per year) and a high volume group (> 10 Whipple procedures per year).

Cost-effectiveness of switching to exemestane after 2 to 3 years of therapy with tamoxifen in postmenopausal women with early-stage breast cancer.

Objectives: Data from the Intergroup Exemestane Study (IES) suggest that switching to the aromatase inhibitor, exemestane, after 2 to 3 years of tamoxifen therapy prolongs disease-free survival versus continuing on tamoxifen therapy. We sought to evaluate the cost-effectiveness of this management strategy.

Methods: A Markov model was developed to predict patients' transitions across various health states based on treatment strategy (continuing tamoxifen vs.

Evaluation of top, angle, and side cleaned FIB samples for TEM analysis.

TEM specimens of a LaAlO(3)/SrTiO(3) multilayer are prepared by FIB with internal lift out. Using a Ga(+1) beam of 5 kV, a final cleaning step yielding top, top-angle, side, and bottom-angle cleaning is performed. Different cleaning procedures, which can be easily implemented in a dual beam FIB system, are described and compared; all cleaning types produce thin lamellae, useful for HRTEM and HAADF-STEM work up to atomic resolution.

[Solid pseudopapilar pancreatic tumors: report of 7 cases and review of the literature].

Introduction: The cystic tumors of the pancreas represent an uncommon entity and the less frequent type among them is the solid pseudopapillary tumor of the pancreas. Its main difference lies in the fact that this type of tumor is more frequent in young patients. Solid pseudopapillary tumors are generally tumors of large size and the majority of them have a benign behavior.

[Surgical treatment of giant serous cystadenoma of pancreas: report of two cases].

Introduction: The cystic tumor of the pancreas is a relatively uncommon entity. There are different types of pancreatic cystic tumors and they all exhibit different degrees of malignancy. These tumors represent 1% of all primary pancreatic tumors and only 15% of the cystic lesions.

[Transduodenal ampullectomy: an useful alternative for the treatment of Vater's ampulla lesions. Case reports of an unfrecuent surgical technique].

The Vater's ampulla neoplasias are not very frequent lesions. The ampullectomy consists on the total resection of the Vater's ampulla and part of the duodenal wall with the later reconstruction and anastomosis of the common bile duct and the Wirsung's duct to the duodenum. The local resection of the ampulla is an alternative to the duodenopancreatectomy that has to be taken into account, especially in benign lesions as in the case of adenomas of the Vater's ampulla.
