Factors associated with trachoma in persistently endemic setting in Southern Ethiopia: a community-based cross-sectional study.

Introduction: in Ethiopia, despite implementing decades-long surgery, antibiotics, facial cleanliness, and environmental improvement interventions, commonly known as the SAFE strategies, persistence and recrudescence of trachoma are common. There is limited evidence that explained the reasons. This study assesses factors associated with trachoma in persistently endemic settings.

Genome-wide transcriptional response to silver stress in extremely halophilic archaeon Haloferax alexandrinus DSM 27206.

Background: The extremely halophilic archaeon Haloferax (Hfx.) alexandrinus DSM 27206 was previously documented for the ability to biosynthesize silver nanoparticles while mechanisms underlying its silver tolerance were overlooked. In the current study, we aimed to assess the transcriptional response of this haloarchaeon to varying concentrations of silver, seeking a comprehensive understanding of the molecular determinants underpinning its heavy metal tolerance.

Comprehensive mineralogical and physicochemical characterization of recent sapropels from Romanian saline lakes for potential use in pelotherapy.

In this study we aimed to compare the mineralogical, thermal, physicochemical, and biological characteristics of recent organic carbon-rich sediments ('sapropels') from three geographically distant Romanian lakes (Tekirghiol and Amara, SE Romania, and Ursu, Central Romania) with distinct hydrogeochemical origins, presently used for pelotherapy. The investigated lakes were classified as inland brackish Na-Cl-sulfated type (Amara), coastal moderately saline and inland hypersaline Na-Cl types (Tekirghiol and Ursu, respectively). The settled organic matter is largely composed of photosynthetic pigments derived from autochthonous phytoplankton.

Needling and open filtering bleb revision after XEN-45 implantation-a retrospective outcome comparison.

Purpose: To compare efficacy and safety of needling and open bleb revision after XEN-45 surgery.

Methods: This retrospective study represents real-life data of patients who underwent XEN-45 surgery between November 2014 and June 2018 in the Vienna General Hospital. The following groups were formed for data evaluation: (PSEA) primary surgery secondary intervention allowed (n = 268); (PS) primary surgery until secondary intervention (n = 268); (N) first needling until additional secondary intervention (n = 55); (BR) first bleb revision until additional secondary intervention (n = 105).

Physiological response to silver toxicity in the extremely halophilic archaeon Halomicrobium mukohataei.

Adaptive strategies responsible for heavy metal tolerance were explored in the extremely halophilic archaeon Halomicrobium mukohataei DSM 12286. The tested strain was seemingly able to overcome silver-induced oxidative stress (assessed by malondialdehyde quantification, catalase assay and total antioxidant capacity measurement) mainly through non-enzymatic antioxidants. Energy dispersive spectrometry analysis illustrated the presence of colloidal silver in Hmc.

The impact of cation concentration on Microcystis (cyanobacteria) scum formation.

Cyanobacterial scums at the surface of the lakes are potentially harmful phenomena with increasing occurrence in the last decades, and the causes that lead to their formation are still an unresolved issue. In order to better understand what triggers the scums, we investigated the effect of several Mg and Ca ion concentrations in promoting them in eight Microcystis aeruginosa strains. The possibility to prevent scum formation by using the ion chelator EDTA was also explored.

Human calf muscles changes after strength training as revealed by diffusion tensor imaging.

Background: Diffusion tensor imaging (DTI) is a non-invasive MR technique widely employed to study muscle anatomy. DTI parameters have been used to investigate microstructural changes dependent on demographic factors or transient condition such as exercise. The present study is aimed at investigating the diffusion parameters changes of the human calf muscles after a 3-months strength training protocol.

Status of faecal pollution in ports: A basin-wide investigation in the Adriatic Sea.

Ports are subject to a variety of anthropogenic impacts, and there is mounting evidence of faecal contamination through several routes. Yet, little is known about pollution in ports by faecal indicator bacteria (FIB). FIB spatio-temporal dynamics were assessed in 12 ports of the Adriatic Sea, a semi-enclosed basin under strong anthropogenic pressure, and their relationships with environmental variables were explored to gain insight into pollution sources.

Evaluation of heart rate recovery in relation to playing position in professional soccer players.

Aim: The aim of the study was the evaluation of the autonomic cardiac function in professional soccer players by heart rate recovery (HRR) measurement after 1' or 2' of active recovery (HRR1 or HRR2, respectively) from an exercise stress test.

Methods: Ninety-two adult professional soccer players (aged 25.27 ± 4.

Contribution of traditional birth attendants to the formal health system in Ethiopia: the case of Afar region.

Background: Traditional birth attendants (TBAs) have been a subject of discussion in the provision of maternal and newborn health care. The objective of this study was to assess the role of trained traditional birth attendants in maternal and newborn health care in Afar Regional State of Ethiopia.

Methods: A qualitative study was used where 21 in-depth interviews and 6 focus group discussions were conducted with health service providers, trained traditional birth attendants, mothers, men, kebele leaders and district health personnel.

A retrospective analysis of hospitalized patients with documented deep-venous thrombosis and their risk of pulmonary embolism.

The question of when and how intensively patients with deep-venous thrombosis (DVT) can ambulate remains scarcely underlined. The authors evaluated the evolution of DVT by comparing bed rest and mobilization and using all variables potentially relevant to a risk/benefit evaluation in 252 patients. The end points were the progression of the thrombotic disease and the incidence of pulmonary embolism (PE) at 30 days.

Chlordiazepoxide and dizocilpine, but not morphine, selectively impair acquisition under a novel repeated-acquisition and performance task in rats.

Rationale: Some classes of drugs can selectively affect learning (i.e., acquisition of behavior) at doses that do not affect performance (i.

Heparin-coated versus uncoated extracorporeal circuit in patients undergoing coronary artery bypass graft surgery.

Setting: Tertiary care academic medical center.

[Compression therapy in deep venous thrombosis].

External compression, both intermittent by pneumatic pumps and continuous by anelastic or elastic bandages and by graduate compression stockings, play a pivotal role in prophylaxis of Deep Venous Thrombosis (DVT). The use of external compression in DVT therapy and in prophylaxis of pulmonary embolism (PE) and of post-thrombotic syndrome has not been validated as well as in DVT prophylaxis. The pathophysiologic properties of the external compression and the most recent evidences about the early mobilization of the patients with DVT and about Low Molecular Weight Heparin (LMWH) therapy suggest the advantages of the external compression.

[Physical treatment of deep venous thrombosis: bed rest or mobilization?].

The need of prolonged bed-rest for the treatment of Deep Venous Thrombosis (DVT), which was considered essential to control the thrombotic phenomenon and to prevent Pulmonary Embolism (PE) until ten years ago, has now been critically reviewed in the light of the great success of the Low Molecular Weight Heparin (LMWH) in medical therapy of DVT. There is a great evidence for bed-rest and immobility to play a pivotal role in the growth and in the progression of a venous thrombosis. The Authors emphasize, both on the international reports and their own experience, that, in most cases, medical treatment of DVT consists of an outpatient--ambulatory care based on immediate mobilization and ambulation, on external compression therapy, on early LMWH administration and late oral anticoagulation.

Postphlebitic syndrome: clinical activity and tolerability of desmin, new LMW dermatan sulfate.

One hundred patients suffering from postphlebitic syndrome of the lower limbs were enrolled in an open, randomized, and multicenter (six centers) trial for a period of eighteen months. Patients were randomly assigned to three treatment groups to receive (for ninety consecutive days) Desmin, a new low-molecular-weight dermatan sulfate, at the dose, respectively, of 100 mg once daily by subcutaneous (SC) route (36 patients), 100 mg twice a day by SC route (33 patients), and 200 mg once daily by intramuscular (IM) route (31 patients). The general and local tolerability and the clinical efficacy of the drug were evaluated by means of clinical, instrumental, and laboratory parameters.

[Diarrhea associated with antibiotic therapy].

The authors suggest rational procedures to prevent the antibiotic associated diarrhea (AAD) Clostridium difficile positive or not, considering its high cost (both to stay in Hospital and for specific therapy). Twenty-four cases of diarrhea starting during antibiotic therapy and until one month from its interruption was assessed. Twelve (50%) was found Clostridium difficile (+); 12 (50%) was Clostridium difficile (-); no case of pseudomembranous colitis was found.
