A Multimodal Intervention to Improve Guideline-Based Screening for Alpha-1 Antitrypsin Deficiency in a Community Health Setting.

Rationale: Evidence-based guidelines recommend screening all individuals with chronic obstructive pulmonary disease (COPD) for the genetic disorder alpha-1 antitrypsin deficiency (AATD). However, it is estimated that only 5% of people with COPD have been tested for AATD, and a large fraction of the estimated 70,000 to 100,000 Americans with AATD have not yet been diagnosed. Low familiarity with AATD and limited knowledge about diagnostic tests and available treatments contribute to suboptimal screening rates.

HIV Testing Deserts and Vulnerability Among Adolescents and Young Adults in Tampa Bay, Florida.

Purpose: Human immunodeficiency virus (HIV) burden among Florida adolescents and young adults (AYA, aged 13-24 years), particularly in Tampa Bay, is among the highest in the nation. We sought to determine the association between zip code-level test site accessibility and AYA HIV burden, compare this association with adult (aged 25-44 years) HIV burden, and identify local AYA HIV testing deserts. We further aimed to identify the association between test site accessibility and population-level markers of social disadvantage.

S-values for radium-223 and absorbed doses estimates for RACL using three computational phantoms.

Radium-223 dichloride (RaCl2), approved by FDA (Food and Drug Administration) in 2013 and in Brazil by ANVISA (Agência Nacional de Vigilância Sanitária) in 2016, offers a new therapeutic option for bone metastases from castration-resistant prostate cancer (CRPC). The advantages of radionuclide therapy for bone metastases include the simultaneous treatment of multiple lesions at the same time. The activity prescription is based on the patient's body weight, disregarding the absorbed dose limit of 2 Gy in the organ at risk: bone marrow.

Optimal theranostic SPECT imaging protocol for 223radium dichloride therapy.

Radium dichloride image-based individual dosimetry requires an optimal acquisition and reconstruction protocol and proper image correction methods for theranostic applications. To assess this problem, radium-223 dichloride SPECT images were acquired from a Jaszczak simulator with a dual-headed gamma camera, LEHR collimator, 128 × 128 matrix, and total time of 32 minutes. A cylindrical PMMA phantom was used to calibrate the measurements performed with Jaszczak.

Sarcopenia, body composition and factors associated with variceal gastrointestinal bleeding and splenectomy in hepatosplenic schistosomiasis mansoni.

Background: Sarcopenia is a common complication of cirrhosis and an important predictor of morbimortality. We aimed to determine the prevalence of sarcopenia and its associated factors in hepatosplenic schistosomiasis (HSS) as well as to evaluate whether muscle mass and function are associated with variceal upper gastrointestinal bleeding (VUGIB) and previous splenectomy in subjects without other liver diseases.

Methods: We conducted a cross-sectional study including adults with HSS who underwent clinical, biochemical, anthropometric, muscle strength and physical performance evaluations and were submitted to bioelectrical impedance analysis and abdominal ultrasound.

Research to law: A qualitative study of Massachusetts' 2018 Care Act expanding emergency department initiation of medication for opioid use disorder.

Background: Initiating medication for opioid use disorder (MOUD) during emergency department (ED) visits is an important innovation to engage individuals in addiction treatment. In 2018, Massachusetts passed the CARE Act, becoming the first state to legislate that hospitals with EDs must be able to offer MOUD. We performed a qualitative study to explore factors influencing policy enactment.

Noninvasive predictors of esophageal varices in patients with hepatosplenic schistosomiasis mansoni.

Background: No previous study have evaluated transient elastography for predicting esophageal varices in hepatosplenic schistosomiasis.

Aim: To investigate noninvasive methods of predicting esophageal varices in patients with hepatosplenic schistosomiasis mansoni.

Methods: Cross-sectional multicentric study included 51 patients with hepatosplenic schistosomiasis.

Liver stiffness is able to differentiate hepatosplenic Schistosomiasis mansoni from liver cirrhosis and spleen stiffness may be a predictor of variceal bleeding in hepatosplenic schistosomiasis.

Background: Ultrasonography is limited for differentiating portal hypertension due to liver cirrhosis from that secondary to hepatosplenic schistosomiasis (HSS). We aimed to investigate the role of transient elastography (TE) in differentiating HSS mansoni from cirrhosis and the factors associated with liver and spleen stiffness (LS and SS) in HSS.

Method: A cross-sectional study was conducted including patients with HSS mansoni (n=29) and liver cirrhosis due to non-alcoholic steatohepatitis (n=23).

Portal vein thrombosis in patients with hepatosplenic schistosomiasis who underwent oesophagogastric devascularization combined with splenectomy.

Background: Portal vein thrombosis (PVT) has been described in nearly 50% of patients who underwent oesophagogastric devascularization combined with splenectomy (EGDS), but no previous study has compared its occurrence in surgical and non-surgical groups. This study aimed to investigate PVT in hepatosplenic schistosomiasis (HSS) and its association with EGDS and upper variceal bleeding (UVB).

Methods: Retrospectively, 104 HSS individuals were enrolled.

Changes in gene expression in European eels (Anguilla anguilla) induced by infection with swim bladder nematodes (Anguillicola crassus).

The European eel, Anguilla anguilla, is considered an endangered species that is under pressure for many reasons. Among others, the introduced parasite Anguillicola crassus is thought to play an important role in the decline of eel populations. These nematodes have been shown to negatively affect many fitness-related traits in eels, e.

Dynamic expression of immune response genes in the sea bass, Dicentrarchus labrax, experimentally infected with the monogenean Diplectanum aequans.

The sea bass, Dicentrarchus labrax, is one of the most extensively farmed marine fishes in the Mediterranean. Under the high-density condition common in aquaculture, the monogenean gill parasite Diplectanum aequans can cause significant economic losses. This study used real-time quantitative PCR to investigate the dynamic expression of immune response genes in sea bass infected with Diplectanum aequans.

Genetically modified organisms in the United States: implementation, concerns, and public perception.

We examine the state of biotechnology with respect to genetically modified (GM) organisms in agriculture. Our focus is on the USA, where there has been significant progress and implementation but where, to date, the matter has drawn little attention. GM organisms are the result of lateral gene transfers, the transfer of genes from one species to another, or sometimes, from one kingdom to another.
