Prcis: Preserflo surgery is a safe procedure, effective in reducing intraocular pressure into the "low teens," surgical survival is greatest in cases of high baseline intraocular pressure (above 21 mm Hg) and when performed as a standalone procedure.

Purpose: To evaluate midterm surgical survival and safety profile of Preserflo filtering surgery.

Methods: In this retrospective, cohort study, consecutive patients who underwent standardized Preserflo implantation with mitomycin C from December 2019 to April 2021 were included.

Purpose: To evaluate bleb morphology features of different glaucoma drainage devices (GDD) using magnetic resonance imaging (MRI).

Materials And Methods: Prospective cohort study of GDD and bleb morphology in consecutive glaucoma patients implanted with Ahmed Glaucoma Valve (AGV), Paul Glaucoma Implant (PGI), Baerveldt Glaucoma Implant (BGI) and Ahmed ClearPath (ACP) devices. Thirty-six eyes from 30 consecutive patients underwent standardized GDD implantation followed by MRI at least 1 month after surgery.

Purpose: This study describes the virtual clinic triage system implementation process at Hospital Santa Maria-Centro Hospitalar Universitário Lisboa Norte (HSM-CHULN) and analyzes its results regarding healthcare outcomes for the patients and the system.

Methods: A retrospective analysis was performed, comparing two cohorts (pre-virtual cohort; virtual triage cohort). Outcomes related to waiting time, number of hospital visits, decisions at first contact, and ancillary exam-based decisions were reported.

Prcis: The PAUL Glaucoma Implant is an effective intraocular pressure (IOP)-lowering device with an acceptable safety profile. Its design as a nonvalved device with a small tube diameter using a vicryl ligation suture around the tube that is posteriorly reabsorbed instead of an ab luminal stent makes it an option in cases selected for glaucoma drainage device implantation.

Purpose: The aim was to determine the 1-year efficacy and safety of PAUL Glaucoma Implant using a uniform, standardized surgical procedure.

Purpose: To compare outcomes of primary trabeculectomy using either mitomycin C (MMC) alone versus MMC augmented with intracamerular bevacizumab in patients with open-angle glaucoma.

Methods: Retrospective, cohort, two-centre, comparative study. Patients' data were screened between October 2015 and March 2019, with inclusion requiring a minimum follow-up of 24 months.

Background: Ciclo plasty using high-intensity focused ultrasound (HIFU) technology acts through the selective coagulation of the ciliary body. Our aim was to evaluate the safety and efficacy profiles of 8-s probe HIFU cyclocoagulation using the EyeOP1 device.

Methods: Prospective pragmatic trial.

Aim: Comparing outcomes after combined phacoemulsification, two iStents insertion and endocyclophotocoagulation (ECP) versus phacoemulsification-iStents alone.

Methods: This is a longitudinal retrospective 12 months study in eyes with ocular hypertension or early-to-moderate open angle glaucoma. Level of disease, intraocular pressure (IOP) and tolerance of glaucoma medication were considered before planning surgery.

Purpose: The aim of this study is to assess the agreement between manual and automated gonioscopy for iridocorneal angle opening.

Methods: The research is a cross-sectional observational study. Manual and automated gonioscopy were performed to consecutive patients in a glaucoma clinic.

Purpose: The XEN gel stent is a minimally invasive surgical device aimed at creating a subconjunctival drainage of aqueous humor, thereby reducing intraocular pressure (IOP). Being a novel device, doubts remain with regard to the efficacy and safety of its implantation in the early stage of new users. This paper illustrates the XEN implantation learning curve, assessed through several surgeons of different expertise.

The present study aimed to gather baseline information about chimpanzee nesting and density in Lagoas de Cufada Natural Park (LCNP), in Guinea-Bissau. Old and narrow trails were followed to estimate chimpanzee density through marked-nest counts and to test the effect of canopy closure (woodland savannah, forest with a sparse canopy, and forest with a dense canopy) on nest distribution. Chimpanzee abundance was estimated at 0.

In this work, we studied the ecological interactions between grape berry microorganisms and Drosophila sp. flies involved in sour rot disease during grape ripening. After veráison the total microbial counts of grape berries affected by sour rot increased from about 2 log CFU/g of berries to more than 7 log CFU/g.

This study investigated the microbiota of sour rotten wine grapes and its impact on wine fermentations. Yeasts, lactic acid bacteria (LAB) and acetic acid bacteria (AAB) were enumerated and identified on sound and sour rot grapes during the ripening stage. The alteration of the ecological balance induced by sour rot was particularly evidenced by the unequivocal increase of yeast and AAB counts on rotten grapes, since the beginning of ripening.

In the present work, the aroma profiles of wines elaborated from sound and sour rot-infected grapes as raw material have been studied by sensory analysis, gas chromatography-olfactometry (GC-O), and gas chromatography-mass spectrometry (GC-MS), with the aim of determining the odor volatiles most likely associated with this disease. The effect of sour rot was tested in monovarietal wines produced with the Portuguese red grape variety Trincadeira and in blends of Cabernet Sauvignon and sour rotten Trincadeira grapes. Wines produced from damaged berries exhibited clear honey-like notes not evoked by healthy samples.

Cantanhez National Park in southern Guinea-Bissau is a mosaic of forest, mangrove, savanna, and agricultural fields, with a high prevalence of oil-palm trees (Elaeis guineensis). It hosts many different animal species, including the chimpanzee (Pan troglodytes verus). Very little is known about the ecology of chimpanzees inhabiting this area.

The wine spoilage yeast Dekkera bruxellensis was evaluated for the production of 4-ethylphenol under low concentrations (0.02-20 g L(-1)) of glucose and fructose in synthetic media. Measurable amounts of 4-ethylphenol were produced over 0.

Yeast species of sound and sour rot-damaged grapes were analysed during fermentation and grape ripening in the vineyard, using general and selective culture media. During 2003 and 2004 vintages, microvinifications were carried out with sound grapes to which different amounts of grapes with sour rot were added. The wine spoilage species Zygosaccharomyces bailii was only recovered during fermentations with sour rot, reaching 5.

A total of 63 strains of Dekkera bruxellensis and 32 strains of Pichia guilliermondii isolated from wine related environments were identified by restriction analysis of the 5.8S-ITS region of the rDNA. These strains were subjected to intraspecific discrimination using mtDNA restriction and RAPD-PCR analysis.
