Effects of dual-task interventions on gait performance of patients with parkinson’s disease: a systematic review
OBJECTIVE: Parkinson’s disease is characterized by motor and non-motor symptoms that impair patients’ gait performance, especially while performing dual/concurrent tasks. These deficits impair patients’ daily function, because dual-tasking is a crucial ability in terms of everyday living. The aim of this study was to systematically review the effects of dual task interventions on gait performance of patients with Parkinson’s disease.
METHOD: Studies were retrieved from MEDLINE/PubMed, LILACS and SciELO. We used the PICOS strategy to determine eligibility criteria. The search strategy included an advanced search on the included databases, using the following search query: “Parkinson’s Disease” AND “Double Task” OR “Concurrent Tasks” OR “Gait” AND “Walk”. Study selection was carried out by two independent researchers and a third one was called when consensus was needed.
RESULTS: A total of 188 articles were identified: 169 articles from Medline/PubMed, 10 articles in SciELO, 8 articles in LILACS and 1 item from manual searches. A total of 56 articles were analyzed regarding the eligibility and exclusion criteria based on full text. A final total of 7 studies were included in the systematic review.
CONCLUSION: The different types of dual-task interventions reported (dance, sound stimuli, visual and somatosensory) were associated to improvements in several gait performance indicators of Parkinson’s disease patients, including gait speed, stride time and length, cadence and step length. External stimuli seem to play a critical role on specific training effects on dual-task gait performance.info:eu-repo/semantics/publishedVersio
Psychotropic drugs and liver disease : a critical review of pharmacokinetics and liver toxicity

selected by an in-house editor and fully peer-reviewed by external reviewers. It is distributed in accordance with the Creative Commons Attribution Non Commercial (CC BY-NC 4.0) license.The liver is the organ by which the majority of substances are metabolized, including psychotropic drugs. There are several pharmacokinetic changes in end-stage liver disease that can interfere with the metabolization of psychotropic drugs. This fact is particularly true in drugs with extensive first-pass metabolism, highly protein bound drugs and drugs depending on phase I hepatic metabolic reactions. Psychopharmacological agents are also associated with a risk of hepatotoxicity. The evidence is insufficient for definite conclusions regarding the prevalence and severity of psychiatric drug-induced liver injury. High-risk psychotropics are not advised when there is pre-existing liver disease, and after starting a psychotropic agent in a patient with hepatic impairment, frequent liver function/lesion monitoring is advised. The authors carefully review the pharmacokinetic disturbances induced by end-stage liver disease and the potential of psychopharmacological agents for liver toxicity.info:eu-repo/semantics/publishedVersio
Validation of a peptide nucleic acid fluorescence in situ hybridization for the specific detection of salmonella species in food matrices
Salmonella is a Gram-negative flagellated rod-shaped bacterium that is one of the most important etiological agents in bacterial foodborne diseases [1,2]. Despite human salmonellosis generally presenting as a self-limiting episode of enterocolitis, the infection can degenerate into chronic and debilitating conditions [2]. To diagnose a Salmonella infection, standard cultural methods are routinely used, which implies bacterial identification by biochemical and serological tests, to confirm the suspect colonies grown on the selective agar [3]. However, this methodology is time-consuming and takes too long to deliver the results [4]. Due to these limitations, more rapid techniques for detection have been developed [5-7]. For that, in this study, we developed a novel Peptide Nucleic Acid Fluorescence in situ Hybridization (PNA FISH) method for the specific detection of Salmonella spp.
The method was based on a new PNA probe, SalPNA1692, coupled with a novel blocker probe in a 1:1 ratio. The method was optimized for the detection of Salmonella in food samples through an evaluation of several rich and selective enrichment broths. The best outcome was achieved using Buffered Peptone water as a pre-enrichment for 24 h followed by 16 h of selective enrichment in RambaQuick broth. For validation in food samples, fresh ground beef was artificially contaminated with two ranges of inoculum: a low level (0.22 CFU/25 g) and a high level (210 CFU/25 g). For both levels of contamination, the confirmed positives were the same comparing the PNA-FISH method and the reference method (ISO 6579-1: 2017). The new PNA-FISH method presented a specificity of 100 % and is a faster time-to-result method, making it a good candidate for routine application in food safety laboratories.info:eu-repo/semantics/publishedVersio
TREATMENT OF COGNITIVE DEFICITS IN ALZHEIMER\u27S DISEASE: A PSYCHOPHARMACOLOGICAL REVIEW
The growing and aging population has contributed to the increased prevalence of Alzheimer\u27s disease (AD) and other types of
dementia in the world. AD is a progressive and degenerative brain disease with an onset characterized by episodic memory
impairments, although progressive deficits can be observed in several domains including language, executive functions, attention
and working memory. The relationship between cognitive impairments and the topography and progression of brain neuropathology
is well established. The pathophysiologic mechanisms and processes that underline the course of cognitive and clinical decline have
been the theoretical support for the development of pharmacological treatments for AD. Cholinesterase inhibitors (ChEIs) and Nmethyl-
D-aspartate (NMDA) antagonists are the main drugs used in the management of global cognitive impairment and several
studies also explore the effects of both in specific cognitive measures. Recent research trends also examine the effects of combination
therapy using both compounds. This review aims to update practical recommendations for the treatment of global cognitive
functioning and specific neurocognitive deficits in AD using ChEIs, NMDA antagonists and combination therapy with both drugs
MAMMALS IN PORTUGAL : A data set of terrestrial, volant, and marine mammal occurrences in P ortugal
Mammals are threatened worldwide, with 26% of all species being includedin the IUCN threatened categories. This overall pattern is primarily associatedwith habitat loss or degradation, and human persecution for terrestrial mam-mals, and pollution, open net fishing, climate change, and prey depletion formarine mammals. Mammals play a key role in maintaining ecosystems func-tionality and resilience, and therefore information on their distribution is cru-cial to delineate and support conservation actions. MAMMALS INPORTUGAL is a publicly available data set compiling unpublishedgeoreferenced occurrence records of 92 terrestrial, volant, and marine mam-mals in mainland Portugal and archipelagos of the Azores and Madeira thatincludes 105,026 data entries between 1873 and 2021 (72% of the data occur-ring in 2000 and 2021). The methods used to collect the data were: live obser-vations/captures (43%), sign surveys (35%), camera trapping (16%),bioacoustics surveys (4%) and radiotracking, and inquiries that represent lessthan 1% of the records.

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries
Abstract
Background
Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.
Methods
This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries.
Results
In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.
Conclusion
This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
