Impact of oral azithromycin and intermittent preventive treatment with sulfadoxine-pyrimethamine regimen on child mortality in Sierra Leone: trial protocol for a randomised, two-arm, double-blinded, placebo-controlled clinical trial (ICARIA).

Background: Azithromycin has been shown to be beneficial in preventing infectious diseases, including malaria, infectious diarrhoea and pneumonia. A cluster randomised control trial on azithromycin MDA in children in Niger, Malawi and Tanzania found a reduction in all-cause under-five (U5) mortality in communities who received azithromycin compared to placebo. However, the reduction was largest and statistically significant only in Niger.

[Mitochondrial diseases and urolithiasis: Is there an association? Literature review about 2 cases].

Unlabelled: Urolithiasis corresponds to the formation of stones in the urinary tract. It is a multifactorial metabolic disorder; its formation is related to oxidative stress and inflammatory processes. The mitochondria, for its part, is an intracellular organelle that plays a role in the regulation of intracellular oxidative stress and intracellular calcium homeostasis, both processes related to urolithiasis.

A practical approach to the endoscopic management of biliary strictures after liver transplantation.

Biliary tract complications are an important cause of morbidity and mortality after liver transplantation (LT) occurring in 5% to 25% of patients. The most common biliary complication in LT recipients are strictures representing approximately half of these biliary adverse events. Bile duct strictures can be divided into anastomotic biliary strictures (ABS) and non-anastomotic biliary strictures (NABS) depending on their location in the biliary tree, being ABS the most encountered type.

Utility of Urgent Endoscopic Retrograde Cholangiopancreatography in Patients with Predicted Mild Acute Pancreatitis and Cholestasis.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) within 72 h is suggested for patients presenting with acute biliary pancreatitis (ABP) and biliary obstruction without cholangitis. This study aimed to identify if urgent ERCP (within 24 h) improved outcomes compared to early ERCP (24-72 h) in patients admitted with predicted mild ABP.

Methods: Patients admitted for predicted mild ABP defined as a bedside index of severity in acute pancreatitis score < 3 and underwent ERCP for biliary obstruction within 72 h of presentation during the study period were included.

The Effects of an Eight-Week Integrated Functional Core and Plyometric Training Program on Young Rhythmic Gymnasts' Explosive Strength.

Background: Explosive strength is essential for rhythmic gymnasts’ performance. It has been suggested that core stability (CS) and plyometric training can enhance athletes’ explosive strength. Nevertheless, there is some uncertainty about the effects of integrated core and plyometric training (CPT) programs on rhythmic gymnastics (RG) performances.

Possibility of genetic therapy for inherited retinal conditions.

Objective: To evaluate the possibility of gene therapy in patients with inherited ocular conditions and established genetic diagnosis. The secondary objectives were to determine the genetic diagnostic rate and to update the list of genes for which there are ongoing clinical trials or preclinical studies that could allow for gene therapy.

Methods: Observational, retrospective, multicentric study of 177 patients with inherited ocular conditions that underwent genetic testing.

Corrigendum to 'A multicenter analysis of the role of prophylactic transfusion of blood products in patients with cirrhosis and esophageal varices undergoing endoscopic band ligation' [JHEP Reports 6 (2021)].

Identification of Lynch Syndrome Carriers among Patients with Small Bowel Adenocarcinoma.

Background: Small bowel adenocarcinoma (SBA) is a rare disease which can be associated with Lynch syndrome (LS). LS tumors are characterized by the presence of microsatellite instability (MSI) and/or the loss of mismatch repair (MMR) protein expression. In SBA, the frequency of MMR deficient (MMRd) tumors varies from 5% to 35%.

A multicenter analysis of the role of prophylactic transfusion of blood products in patients with cirrhosis and esophageal varices undergoing endoscopic band ligation.

Background & Aims: Prophylactic administration of platelets and fresh frozen plasma (FFP) has been recommended in patients with cirrhosis with low platelets and/or prolonged international normalized ratio (INR) without scientific evidence to support this practice. In this analysis, we evaluated the use of prophylactic administration of blood products in outpatients with cirrhosis undergoing endoscopic band ligation (EBL).

Methods: This is a multicenter retrospective analysis of consecutive EBL procedures in patients with cirrhosis at 4 hospitals in Spain from 01/2010-01/2017.

Biomarkers for Gastric Cancer Screening and Early Diagnosis.

Gastric cancer is one of the most common cancers worldwide, with a bad prognosis associated with late-stage diagnosis, significantly decreasing the overall survival. This highlights the importance of early detection to improve the clinical course of these patients. Although screening programs, based on endoscopic or radiologic approaches, have been useful in countries with high incidence, they are not cost-effective in low-incidence populations as a massive screening strategy.

The human endogenous metabolome as a pharmacology baseline for drug discovery.

We have limited understanding of the variation in in vitro affinities of drugs for their targets. An analysis of a highly curated set of 815 interactions between 566 drugs and 129 primary targets reveals that 71% of drug-target affinities have values above that of the corresponding endogenous ligand, 96% of them fitting within a range of two orders of magnitude. Our findings suggest that the evolutionary optimised affinity of endogenous ligands for their native proteins can serve as a baseline for the primary pharmacology of drugs.

Lokiarchaeota Marks the Transition between the Archaeal and Eukaryotic Selenocysteine Encoding Systems.

Selenocysteine (Sec) is the 21st amino acid in the genetic code, inserted in response to UGA codons with the help of RNA structures, the SEC Insertion Sequence (SECIS) elements. The three domains of life feature distinct strategies for Sec insertion in proteins and its utilization. While bacteria and archaea possess similar sets of selenoproteins, Sec biosynthesis is more similar among archaea and eukaryotes.

Common mutations in Cuban cystic fibrosis patients.

So far, more than 1500 mutations have been reported in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Mutational spectrum varies in accordance with geographic and/or ethnic origin. In this study, we have analyzed seven common CF mutations (p.

[Diagnostic clinical and immunologic characteristics of infection by the human immunodeficiency virus in infants].

Acquired immunodeficiency syndrome (AIDS) in infants has different clinical and immunological characteristics from adult AIDS because of immunological immaturity of the fetus and newborn when infection is produced. Differential diagnosis with primary immunodeficiency diseases, mainly with severe combined immunodeficiency and hypogammaglobulinemia is often difficult, but clinical, epidemiological and immunological data aid in establishing diagnosis. Repeated bacterial infections and abnormal antibody production are common in such children and gammaglobulin therapy is indicated to prevent them and avoid continuous immunological stimulation that viral replication and disease progression.

Hypogammaglobulinaemia and negative anti-HIV antibodies in AIDS.

Repeated bacterial infections are frequent in children with AIDS owing to the B cell abnormalities produced by HIV infection. We report on two infants who presented with hypogammaglobulinaemia and with no HIV antibodies, but with epidemiological, immunological, and clinical features of AIDS.
