Circulating prolactin levels and the effect of dopaminergic agonists in systemic lupus erythematosus: a systematic review and meta-analysis.

This systematic review of clinical studies investigated whether circulating PRL levels differed between subjects with systemic lupus erythematosus (SLE) and healthy controls, the correlation between circulating PRL and SLE activity, and the effect of dopaminergic agonists as adjuvant therapy for SLE. We searched PubMed, Scopus, Web of Science, Cochrane, Embase, and Google Scholar for case-control and cross-sectional studies investigating circulating PRL levels in subjects with SLE and/or its correlation with disease activity, and clinical trials examining the effect of dopaminergic agonists on SLE activity assessed by the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score. Forty-five studies addressing circulating PRL levels in SLE met our inclusion criteria.

Clinical and molecular features of four Brazilian families with multiple endocrine neoplasia type 1.

Objective: Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant syndrome characterized by its clinical variability and complexity in diagnosis and treatment. We performed both clinical and molecular descriptions of four families with MEN1 in a follow-up at a tertiary center in Brasília.

Methods: From a preliminary review of approximately 500 medical records of patients with pituitary neuroendocrine tumor (PitNET) from the database of the Neuroendocrinology Outpatient Clinic of the University Hospital of Brasília, a total of 135 patients met the criteria of at least two affected family members.

"Do it yourself" protocol to fabricate dual-detection paper-based analytical device for salivary biomarker analysis.

This paper describes the design and construction of dual microfluidic paper-based analytical devices (dual-μPADs) as a lab-on-paper platform involving a "do-it-yourself" fabrication protocol. The device comprises a colorimetric and electrochemical module to obtain a dual-mode signal readout sensing strategy. A 3D pen polymeric resin was used to prepare graphite carbon-based electrodes and hydrophobic barriers on paper substrates.

Silicone glue-based graphite ink incorporated on paper platform as an affordable approach to construct stable electrochemical sensors.

This study describes the development of electrochemical paper-based analytical devices (ePADs) using carbon-based paste combining silicone glue and graphite powder. The ePADs were manufactured using the screen-printing technique, which consisted of depositing the conductive ink on a screencast on the paper surface. In addition, an alternative electrical connector was designed and 3D-printed to make the detection method cheaper, portable and reproducible.

Development of a sticker sealed microfluidic device for in situ analytical measurements using synchrotron radiation.

Shedding synchrotron light on microfluidic systems, exploring several contrasts in situ/operando at the nanoscale, like X-ray fluorescence, diffraction, luminescence, and absorption, has the potential to reveal new properties and functionalities of materials across diverse areas, such as green energy, photonics, and nanomedicine. In this work, we present the micro-fabrication and characterization of a multifunctional polyester/glass sealed microfluidic device well-suited to combine with analytical X-ray techniques. The device consists of smooth microchannels patterned on glass, where three gold electrodes are deposited into the channels to serve in situ electrochemistry analysis or standard electrical measurements.

Implementation and Monitoring of a Telemedicine Model in Acromegalic Outpatients in a Low-Income Country During the COVID-19 Pandemic.

Telemedicine is a resource to provide health care to patients social distancing and prevent their exposure to the risk of contamination by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in medical-hospital settings. This study evaluated a virtual model of care in acromegalic patients. We recruited 78 acromegalic patients, 65% female, median age 63 years.

Giant cabergoline-resistant prolactinoma in a man who presented with a psychotic episode during treatment: a case report.

Background: Prolactinomas are tumors of the pituitary gland that usually respond very well to treatment with cabergoline. Resistance to cabergoline is very rare, but when it occurs, it is a difficult problem to resolve if the tumor is inoperable.

Case Presentation: A 62-year-old white man was treated for a giant macroprolactinoma detected during investigation of a subacute subdural hematoma of the left frontal lobe.

Salivary diagnostics on paper microfluidic devices and their use as wearable sensors for glucose monitoring.

Microfluidic paper-based devices (μPADs) and wearable devices have been highly studied to be used as diagnostic tools due to their advantages such as simplicity and ability to provide instrument-free fast results. Diseases such as periodontitis and diabetes mellitus can potentially be detected through these devices by the detection of important biomarkers. This study describes the development of μPADs through craft cutter printing for glucose and nitrite salivary diagnostics.

Prolactinomas Resistant to Treatment With Dopamine Agonists: Long-Term Follow-Up of Six Cases.

Prolactinomas are preferentially treated with dopamine agonists. However, a few adenomas are resistant to this treatment. To evaluate the characteristics of patients with resistance to dopamine agonists in the long-term.

Beneficial Effects of High Doses of Cabergoline in the Treatment of Giant Prolactinoma Resistant to Dopamine Agonists: A Case Report with a 21-Year Follow-Up.

Introduction: Prolactinomas are pituitary tumors with a very low prevalence in childhood and adolescence compared to adulthood. This condition is preferentially treated with dopamine agonists. Resistance to these drugs is rare.

Photochemical Deposition of Silver Nanoparticles on Clays and Exploring Their Antibacterial Activity.

Photochemical method was used to synthesize silver nanoparticles (AgNPs) in the presence of citrate or clay (SWy-1, SYn-1, and Laponite B) as stabilizers and Lucirin TPO as photoinitiator. During the photochemical synthesis, an appearance of the plasmon absorption band was seen around 400 nm, indicating the formation of AgNPs. X-ray diffraction results suggested that AgNPs prepared in SWy-1 were adsorbed into interlamellar space, and moreover, showed some clay exfoliation.

Short-term treatment with cabergoline can lead to tumor shrinkage in patients with nonfunctioning pituitary adenomas.

This study was carried out to evaluate the effectiveness of cabergoline in the treatment of nonfunctioning pituitary adenomas (NFPA), in a short-term follow-up period. Nineteen patients (10 men and 9 women) followed at the University Hospital of Brasilia and harboring nonfunctioning pituitary macroadenomas were enrolled in the study. Eleven patients were previously submitted to transsphenoidal surgery, and in 8 patients no previous treatment had been instituted.
