Characterisation of institutionalised Portuguese older adult fallers: is there a place for pharmacist intervention? A preliminary study.

Background: Falls are a major public health issue, given their prevalence and social impact. Older adults living in long-term care facilities (LTCF) are at greater risk of injury resulting from a fall due to multiple factors, such as nutritional, functional/cognitive impairment, postural instability, polypharmacy, and the presence of potentially inappropriate medications (PIMs). Medication management in LTCF is complex and often sub-optimal and might be crucial for falls.

Long-term cholecalciferol supplementation in hemodialysis patients: Effects on mineral metabolism, inflammation, and cardiac parameters.

Background: Low levels of 25-hydroxyvitamin D [25(OH)D] are frequent in chronic kidney disease and are associated with adverse outcomes. The aim of this 5-year prospective study was to evaluate the effects of cholecalciferol supplementation on mineral metabolism, inflammation and cardiac parameters in hemodialysis (HD) patients.

Methods: The study included 97 patients.

Bone fracture risk factors in prevalent hemodialysis patients.

Bone fractures are an important cause of morbidity and mortality in hemodialysis (HD) patients. The aim of this study was to quantify the incidence of fractures in a cohort of prevalent HD patients and evaluate its relationship with possible risk factors. We performed a retrospective analysis of 341 patients, since they started HD (median of 51 months).

Relationship between bioimpedance-determined body composition and peritoneal transport in peritoneal dialysis.

Purpose: In peritoneal dialysis (PD) patients, body fluid homeostasis is dependent on peritoneal elimination of water and solutes. Patients with less favorable peritoneal transport parameters should be more overhydrated. Despite this, the association between faster transport and overhydration (OH) is weak, and the factors that influence hydration status are still poorly characterized.

Candida tropicalis biofilm and human epithelium invasion is highly influenced by environmental pH.

Objective: The main goal of this study was to investigate the role of pH on Candida tropicalis virulence determinants, namely the ability to form biofilms and to colonize/invade reconstituted human vaginal epithelia.

Methods: Biofilm formation was evaluated by enumeration of cultivable cells, total biomass quantification and structural analysis by scanning electron microscopy and confocal laser scanning microscopy. Candida tropicalis human vaginal epithelium colonization and invasiveness were examined qualitatively by epifluorescence microscopy and quantitatively by a novel quantitative real-time PCR protocol for Candida quantification in tissues.

Calcium Acetate/Magnesium Carbonate and Cardiovascular Risk Factors in Chronic Hemodialysis Patients.

Background/aim: Calcium acetate/magnesium carbonate (CaMg) is a recent phosphate binder that has been shown to have protective cardiovascular (CV) effects in animal models. The aim of this study was to evaluate the relationship between CaMg therapy and CV risk markers like pulse pressure (PP), left ventricular mass index (LVMI) and valvular calcifications compared to sevelamer or no phosphate binder (NPB) therapy in chronic hemodialysis (HD) patients.

Methods: We performed a 48-month prospective study in 138 HD patients under hemodiafiltration with a dialysate Mg concentration of 0.

Vulvovaginal candidiasis: Epidemiology, microbiology and risk factors.

Vulvovaginal candidiasis (VVC) is an infection caused by Candida species that affects millions of women every year. Although Candida albicans is the main cause of VVC, the identification of non-Candida albicans Candida (NCAC) species, especially Candida glabrata, as the cause of this infection, appears to be increasing. The development of VVC is usually attributed to the disturbance of the balance between Candida vaginal colonization and host environment by physiological or nonphysiological changes.

Lower serum magnesium is associated with cardiovascular risk factors and mortality in haemodialysis patients.

Background: Hypomagnesaemia is a cardiovascular (CV) risk factor in the general population. The aim of this study was to evaluate the relationship between pre-dialysis magnesium (Mg) and CV risk markers, [including pulse pressure (PP), left ventricular mass index (LVMI) and vascular calcifications (VC)], and mortality in haemodialysis (HD) patients.

Methods: We performed a 48-month prospective study in 206 patients under pre-dilution haemodiafiltration with a dialysate Mg concentration of 1 mmol/l.

Nutritional status and overhydration: can bioimpedance spectroscopy be useful in haemodialysis patients?

Background: Protein-energy wasting (PEW), associated with inflammation and overhydration, is common in haemodialysis (HD) patients and is associated with high morbidity and mortality.

Objective: Assess the relationship between nutritional status, markers of inflammation and body composition through bioimpedance spectroscopy (BIS) in HD patients.

Methods: This observational, cross-sectional, single centre study, carried out in an HD centre in Forte da Casa (Portugal), involved 75 patients on an HD programme.

Open surgical correction combined with an external splint for correction of a non-compliant pectus excavatum in a cat.

A 4-month-old domestic shorthair female cat weighing 1.3 kg was presented for evaluation of respiratory distress. The animal showed evident dyspnoea with exercise intolerance and a marked concave deformation of the sternum.

Cholecalciferol supplementation in hemodialysis patients: effects on mineral metabolism, inflammation, and cardiac dimension parameters.

Background And Objectives: Vitamin D deficiency is highly prevalent in chronic kidney disease. The aim of this study was to evaluate the effects of oral cholecalciferol supplementation on mineral metabolism, inflammation, and cardiac dimension parameters in long-term hemodialysis (HD) patients.

Design, Setting, Participants, & Measurements: This 1-year prospective study included 158 HD patients.

25-Hydroxyvitamin D3, arterial calcifications and cardiovascular risk markers in haemodialysis patients.

Background: Decreased vitamin D serum levels have been recently related to arterial stiffening and vascular calcifications in haemodialysis (HD) patients, but the pathophysiology of this association is not yet clear. The aim of this study was to evaluate the relationship between vascular calcifications, cardiovascular risk factors [including brain natriuretic peptide (BNP), pulse pressure (PP) and left ventricular mass index] and 25-hydroxyvitamin D3 (25(OH)D3) and 1,25-dihydroxyvitamin D3 [1,25(OH)(2)D3] serum levels.

Methods: We performed a cross-sectional study with 223 prevalent HD patients, 48% females, 27% diabetics, with the mean age of 62.
