RESUMEN
In the last decade, several cases affected by Developmental Topographical Disorientation (DTD) have been described. DTD consists of a neurodevelopmental disorder affecting the ability to orient in the environment despite well-preserved cognitive functions, and in the absence of a brain lesion or other neurological or psychiatric conditions. Described cases showed different impairments in navigational skills ranging from topographic memory deficits to landmark agnosia. All cases lacked a mental representation of the environment that would allow them to use high-order spatial orientation strategies. In addition to the single case studies, a group study performed in Canada showed that the disorder is more widespread than imagined. The present work intends to investigate the occurrence of the disorder in 1,698 young Italian participants. The sample is deliberately composed of individuals aged between 18 and 35 years to exclude people who could manifest the loss of the ability to navigate as a result of an onset of cognitive decline. The sample was collected between 2016 and 2019 using the Qualtrics platform, by which the Familiarity and Spatial Cognitive Style Scale and anamnestic interview were administered. The data showed that the disorder is present in 3% of the sample and that the sense of direction is closely related to town knowledge, navigational strategies adopted, and gender. In general, males use more complex navigational strategies than females, although DTD is more prevalent in males than in females, in line with the already described cases. Finally, the paper discusses which protective factors can reduce DTD onset and which intervention measures should be implemented to prevent the spread of navigational disorders, which severely impact individuals' autonomy and social relationships.

Transient global amnesia (TGA) is a clinical syndrome characterized by anterograde amnesia, mild retrograde amnesia, and confusion up to 24 hours. Most commonly seen in patients older than 50 years, TGA results from the temporary impairment of short-term memory formation. Clinically, patients have time disorientation and often ask repeated questions regarding the day's events. Vomiting, headache, blurry vision, dizziness, and nausea may be present. A physically or psychologically stressful precipitating event, such as emotional stress, significant physical exertion, exposure to extreme temperatures, high-altitude conditions, Valsalva maneuver, acute illness, or sexual intercourse, is often the cause. The pathophysiology of TGA is not well understood but may be related to impaired venous drainage of the hippocampus. The diagnosis is primarily clinical, but recent studies suggest that magnetic resonance imaging may be helpful. TGA is self-limited and resolves within 24 hours. There is no established treatment for episodes. The lifetime recurrence rate is 2.9% to 23.8%. Recent evidence suggests an association between TGA and migraine headaches as well as takotsubo cardiomyopathy. No apparent increased risk of cerebrovascular events occurs in patients who have had an episode of TGA. There is conflicting evidence as to whether an episode of TGA predisposes to future seizures or dementia.

The discriminative power of CURB-65 for mortality in community-acquired pneumonia (CAP) is suspected to decrease with age. However, a useful prognostic prediction model for older patients with CAP has not been established. This study aimed to develop and validate a new scoring system for predicting mortality in older patients with CAP. We recruited two prospective cohorts including patients aged ≥ 65 years and hospitalized with CAP. In the derivation (n = 872) and validation cohorts (n = 1,158), the average age was 82.0 and 80.6 years and the 30-day mortality rate was 7.6% (n = 66) and 7.4% (n = 86), respectively. A new scoring system was developed based on factors associated with 30-day mortality, identified by multivariate analysis in the derivation cohort. This scoring system named CHUBA comprised five variables: confusion, hypoxemia (SpO2 ≤ 90% or PaO2 ≤ 60 mmHg), blood urea nitrogen ≥ 30 mg/dL, bedridden state, and serum albumin level ≤ 3.0 g/dL. With regard to 30-day mortality, the area under the receiver operating characteristic curve for CURB-65 and CHUBA was 0.672 (95% confidence interval, 0.607-0.732) and 0.809 (95% confidence interval, 0.751-0.856; P < 0.001), respectively. The effectiveness of CHUBA was statistically confirmed in the external validation cohort. In conclusion, a simpler novel scoring system, CHUBA, was established for predicting mortality in older patients with CAP.

OBJECTIVE: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is protean in its manifestations, affecting nearly every organ system. However, nervous system involvement and its effect on disease outcome are poorly characterized. The objective of this study was to determine whether neurologic syndromes are associated with increased risk of inpatient mortality. METHODS: A total of 581 hospitalized patients with confirmed SARS-CoV-2 infection, neurologic involvement, and brain imaging were compared to hospitalized non-neurologic patients with coronavirus disease 2019 (COVID-19). Four patterns of neurologic manifestations were identified: acute stroke, new or recrudescent seizures, altered mentation with normal imaging, and neuro-COVID-19 complex. Factors present on admission were analyzed as potential predictors of in-hospital mortality, including sociodemographic variables, preexisting comorbidities, vital signs, laboratory values, and pattern of neurologic manifestations. Significant predictors were incorporated into a disease severity score. Patients with neurologic manifestations were matched with patients of the same age and disease severity to assess the risk of death. RESULTS: A total of 4,711 patients with confirmed SARS-CoV-2 infection were admitted to one medical system in New York City during a 6-week period. Of these, 581 (12%) had neurologic issues of sufficient concern to warrant neuroimaging. These patients were compared to 1,743 non-neurologic patients with COVID-19 matched for age and disease severity admitted during the same period. Patients with altered mentation (n = 258, p = 0.04, odds ratio [OR] 1.39, confidence interval [CI] 1.04-1.86) or radiologically confirmed stroke (n = 55, p = 0.001, OR 3.1, CI 1.65-5.92) had a higher risk of mortality than age- and severity-matched controls. CONCLUSIONS: The incidence of altered mentation or stroke on admission predicts a modest but significantly higher risk of in-hospital mortality independent of disease severity. While other biomarker factors also predict mortality, measures to identify and treat such patients may be important in reducing overall mortality of COVID-19.

BACKGROUND: Only little evidence is available on disorientation, one of the most challenging symptoms of Alzheimer's disease and related dementias. OBJECTIVES: The aim of this study was to investigate the prevalence of disorientation in older age in association with the level of cognitive status, personal characteristics, and life events. METHODS: Three longitudinal population-based cohort studies on cognitive health of elderly adults were harmonized (LEILA 75â+â, AgeCoDe/AgeQualiDe, AgeMooDe). Participants who completed a baseline and at least one follow-up assessment of cognitive functioning and who did not have stroke, Parkinson's disease, atherosclerosis, kidney disease, and/or alcoholism were included in the analysis (nâ=â2135, 72.6% female, mean age 80.2 years). Data was collected in standardized interviews and questionnaires with the participant, a proxy informant, and the participant's general practitioner. RESULTS: Making three errors in the MMSE other than in the questions on orientation (MMSEwo) came with a probability of 7.8% for disorientation, making ten errors with a probability of 88.9%. A lower MMSEwo score (HR 0.75, CI 95 0.71-0.79, pâ<â0.001), older age (HR 1.11, CI 95 1.08-1.14, pâ<â0.001), and living in a nursing home (HR 1.64, CI 95 1.02-2.64, pâ=â0.042) were associated with incident disorientation. Impairments in walking (OR 2.41, CI 95 1.16-4.99, pâ=â0.018) were associated with a greater probability for prevalent disorientation. None of the life events were significant. CONCLUSION: Our findings suggest that disorientation is primarily associated with cognitive status. Regular walking activities might possibly reduce the risk for disorientation but further research is necessary.

BACKGROUND: This review was published originally in 1999 and was updated in 2001, 2002, 2009, 2017, and 2020. Updating was deemed necessary due to the high incidence of hip fractures, the large number of official societies providing recommendations on this condition, the possibility that perioperative peripheral nerve blocks (PNBs) may improve patient outcomes, and the major role that PNBs may play in reducing preoperative and postoperative opioid use for analgesia. OBJECTIVES: To compare PNBs used as preoperative analgesia, as postoperative analgesia, or as a supplement to general anaesthesia versus no nerve block (or sham block) for adults with hip fracture. Outcomes were pain on movement at 30 minutes after block placement, acute confusional state, myocardial infarction, chest infection, death, time to first mobilization, and costs of an analgesic regimen for single-injection blocks. We undertook the update to look for new studies and to update the methods to reflect Cochrane standards. SEARCH METHODS: For the updated review, we searched the following databases: the Cochrane Central Register of Controlled Trials (CENTRAL; 2019, Issue 11), in the Cochrane Library; MEDLINE (Ovid SP, 1966 to November 2019); Embase (Ovid SP, 1974 to November 2019); and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (EBSCO, 1982 to November 2019), as well as trial registers and reference lists of relevant articles. SELECTION CRITERIA: We included randomized controlled trials (RCTs) assessing use of PNBs compared with no nerve block (or sham block) as part of the care provided for adults 16 years of age and older with hip fracture. DATA COLLECTION AND ANALYSIS: Two review authors independently screened new trials for inclusion, assessed trial quality using the Cochrane Risk of Bias-2 tool, and extracted data. When appropriate, we pooled results of outcome measures. We rated the certainty of evidence using the GRADE approach. MAIN RESULTS: We included 49 trials (3061 participants; 1553 randomized to PNBs and 1508 to no nerve block (or sham block)). For this update, we added 18 new trials. Trials were published from 1981 to 2020. Trialists followed participants for periods ranging from 5 minutes to 12 months. The average age of participants ranged from 59 to 89 years. People with dementia were often excluded from the included trials. Additional analgesia was available for all participants. Results of 11 trials with 503 participants show that PNBs reduced pain on movement within 30 minutes of block placement (standardized mean difference (SMD) -1.05, 95% confidence interval (CI) -1.25 to -0.86; equivalent to -2.5 on a scale from 0 to 10; high-certainty evidence). Effect size was proportionate to the concentration of local anaesthetic used (P = 0.0003). Based on 13 trials with 1072 participants, PNBs reduce the risk of acute confusional state (risk ratio (RR) 0.67, 95% CI 0.50 to 0.90; number needed to treat for an additional beneficial outcome (NNTB) 12, 95% CI 7 to 47; high-certainty evidence). For myocardial infarction, there were no events in one trial with 31 participants (RR not estimable; low-certainty evidence). From three trials with 131 participants, PNBs probably reduce the risk for chest infection (RR 0.41, 95% CI 0.19 to 0.89; NNTB 7, 95% CI 5 to 72; moderate-certainty evidence). Based on 11 trials with 617 participants, the effects of PNBs on mortality within six months are uncertain due to very serious imprecision (RR 0.87, 95% CI 0.47 to 1.60; low-certainty evidence). From three trials with 208 participants, PNBs likely reduce time to first mobilization (mean difference (MD) -10.80 hours, 95% CI -12.83 to -8.77 hours; moderate-certainty evidence). One trial with 75 participants indicated there may be a small reduction in the cost of analgesic drugs with a single-injection PNB (MD -4.40 euros, 95% CI -4.84 to -3.96 euros; low-certainty evidence). We identified 29 ongoing trials, of which 15 were first posted or at least were last updated after 1 January 2018. AUTHORS' CONCLUSIONS: PNBs reduce pain on movement within 30 minutes after block placement, risk of acute confusional state, and probably also reduce the risk of chest infection and time to first mobilization. There may be a small reduction in the cost of analgesic drugs for single-injection PNB. We did not find a difference for myocardial infarction and mortality, but the numbers of participants included for these two outcomes were insufficient. Although randomized clinical trials may not be the best way to establish risks associated with an intervention, our review confirms low risks of permanent injury associated with PNBs, as found by others. Some trials are ongoing, but it is unclear whether any further RCTs should be registered, given the benefits found. Good-quality non-randomized trials with appropriate sample size may help to clarify the potential effects of PNBs on myocardial infarction and mortality.

OBJECTIVES: The study aimed to establish the current incidence and severity of spatial disorientation (SD) in Polish military pilots when flying different aircraft types over their entire careers, and to determine how SD training and pilots' flight experience might benefit their recognition of situations that may cause SD. MATERIAL AND METHODS: Overall, 176 military Polish pilots (aged 33.8±7.72 years, the number of flying hours: 1194±941) flying different aircraft types, who attended the aviation medicine course, were surveyed and asked to report their episodes of SD. To collect anonymous data, a postal SD questionnaire (INFO PUB 61/117/5) was used. RESULTS: In the overall incidence rate of SD (96%), the most commonly experienced SD illusion was "loss of horizon due to atmospheric conditions" (81%). More SD incidents were reported by pilots who had received SD training. Some differences in the categories of the most commonly experienced SD illusion episodes between aircraft types were found. A severe episode adversely affecting flight safety was categorized by 10% of the respondents. CONCLUSIONS: In Polish military aviation, episodes of SD are a significant threat to aviation safety. There is evidence for the beneficial effects of SD training in the improvement of pilots' ability to recognize those factors that lead to SD. Int J Occup Med Environ Health. 2020;33(6):791-810.

INTRODUCTION: We analysed the neurological complications of patients with severe SARS-CoV-2 infection who required intensive care unit (ICU) admission. PATIENTS AND METHODS: We conducted a retrospective, observational, descriptive study of consecutive patients admitted to the ICU due to severe respiratory symptoms secondary to SARS-CoV-2 infection between 1 April and 1 June 2020. RESULTS: We included 30 patients with neurological symptoms; 21 were men (72.40%), and mean age (standard deviation [SD]) was 57.41 years (11.61). The mean duration of ICU stay was 18.83 days (14.33). The neurological conditions recorded were acute confusional syndrome in 28 patients (93.33%), neuromuscular disease in 15 (50%), headache in 5 (16.66%), cerebrovascular disease in 4 (13.33%), and encephalopathies/encephalitis in 4 (13.33%). CSF analysis results were normal in 6 patients (20%). Brain MRI or head CT showed alterations in 20 patients (66.6%). EEG was performed in all patients (100%), with 8 (26.66%) showing abnormal findings. In 5 of the 15 patients with clinical myopathy, diagnosis was confirmed with electroneuromyography. We found a correlation between older age and duration of ICU stay (P=.002; 95%CI: 4.032-6.022; OR: 3,594). CONCLUSIONS: Severe COVID-19 mainly affects men, as observed in other series. Half of our patients presented acute myopathy, and almost all patients left the ICU with acute confusional syndrome, which fully resolved; no correlation was found with EEG or neuroimaging findings. Older age is associated with longer ICU stay.

BACKGROUND: Gabapentin is prescribed for seizures and pain and has efficacy for treating alcohol use disorder (AUD) starting at doses of 900 milligrams per day (mg/d). Recent evidence suggests safety concerns associated with gabapentin including adverse neurologic effects. Individuals with hepatitis C (HCV), HIV, or AUD may be at increased risk due to comorbidities and potential medication interactions. METHODS: We identified patients prescribed gabapentin for ≥ 60 days for any indication between 2002 and 2015. We propensity-score matched each gabapentin-exposed patient with up to 5 gabapentin-unexposed patients. We followed patients for 2 years or until diagnosed with (i) falls or fractures, or (ii) altered mental status using validated ICD-9 diagnostic codes. We used Poisson regression to estimate incidence rates and relative risk (RR) of these adverse events in association with gabapentin exposure overall and stratified by age, race/ethnicity, sex, HCV, HIV, AUD, and dose. RESULTS: Incidence of falls or fractures was 1.81 per 100 person-years (PY) among 140,310 gabapentin-exposed and 1.34/100 PY among 431,408 gabapentin-unexposed patients (RR 1.35, 95% confidence interval [CI] 1.28 to 1.44). Incidence of altered mental status was 1.08/100 PY among exposed and 0.97/100 PY among unexposed patients, RR of 1.12 (95% CI 1.04 to 1.20). Excess risk of falls or fractures associated with gabapentin exposure was observed in all subgroups except patients with HCV, HIV, or AUD; however, these groups had elevated incidence regardless of exposure. There was a clear dose-response relationship for falls or fractures with highest risk observed among those prescribed ≥ 2,400 mg/d (RR 1.90, 95% CI 1.50 to 2.40). Patients were at increased risk for altered mental status at doses 600 to 2,399 mg/d; however, low number of events in the highest dose category limited power to detect a statistically significant association ≥ 2,400 mg/d. CONCLUSIONS: Gabapentin is associated with falls or fractures and altered mental status. Clinicians should be monitoring gabapentin safety, especially at doses ≥ 600 mg/d, in patients with and without AUD.

AIM: Carbon monoxide (CO) is a colorless, odorless gas and tasteless. CO poisoning (COP) is one of the most frequently encountered inhalation poisonings. The most common cause of morbidity in COP is delayed neurological sequelae (DNS). DNS is the occurrence of neuropsychiatric findings within 2-240â¯days after discharge of patients with COP and there are no definitive diagnostic criteria. The aim of our study is; to determine the risk factors and incidence of DNS. METHOD: Our study is a retrospective, observational study. Patients with the diagnosis of COP in the emergency department between 2015 and 2016 were included in the study. Patients age, gender, findings in the initial physical examination (PE) and neurological examination (NE), blood carboxyhemoglobin (COHb) level, relation between hyperbaric oxygen (HBO) treatment and DNS were assessed. RESULTS: Total of 72 patients were included in the study. Mean age was 33.43⯱â¯20.89. It was determined that pathological findings in the initial NE are a significant predictive factor for DNS (Odds ratio 18.600, p:0.004). Significant relation between NE and HBO treatment was present (p:00.1). There was no statistically significant relationship between initial COHb level and receiving HBO treatment (p:0.9). Median COHb level of patients with DNS was 30 (min:10, max: 43), median COHb level of patients without DNS was 25 (min:10, max:44) and there was no statistically significant relationship between the two groups according to COHb levels (p:0.7). CONCLUSION: Pathological findings in the initial neurological examination had a predictive value for delayed neurological sequelae in patients with carbon monoxide poisoning.

Non-convulsive status epilepticus (NCSE) is a potentially treatable condition that poses considerable diagnostic challenges. NCSE is thought to be more common in the elderly than in the general population, however additional diagnostic challenges complicate its recognition in older patients, because of the wide differential diagnosis with common underlying causes of acute confusional state in this age group. We set out to review the existing evidence on the clinical correlates of NCSE in the elderly population. A systematic literature review was conducted according to the methodological standards outlined in the PRISMA statement to assess the clinical correlates of NCSE in patients aged 60 or older. Our literature search identified 11 relevant studies, which confirmed that the incidence of NCSE increases with age, in particular with regard to focal forms with impairment of consciousness. Female gender, history of epilepsy (or a recently witnessed seizure with motor features), and abnormal ocular movements appeared to correlate with the diagnosis of NCSE in the elderly, prompting prioritization of electroencephalography tests for diagnostic confirmation. Epidemiological data in the elderly vary widely because of the heterogeneity of definitions and diagnostic criteria applied across different studies. Based on our findings, it is recommended to keep a low threshold for requesting electroencephalography tests to confirm the diagnosis of NCSE in elderly patients with acute confusional state, even in the presence of a presumed symptomatic cause.

Background and Purpose- Nonfocal transient neurological attacks (TNAs), such as unsteadiness, bilateral weakness, or confusion, are associated with an increased risk of stroke and dementia. Cerebral ischemia plays a role in their pathogenesis, but the precise mechanisms are unknown. We hypothesized that cerebral small vessel disease is involved in the pathogenesis of TNAs and assessed the relation between TNAs and manifestations of cerebral small vessel disease on magnetic resonance imaging. Methods- We included participants from the HBC (Heart-Brain Connection) study. In this study, hemodynamic and cardiovascular contributions to cognitive impairment have been studied in patients with heart failure, carotid artery occlusion, or possible vascular cognitive impairment, as well as in a reference group. We excluded participants with a history of stroke or transient ischemic attacks. The occurrence of the following 8 TNAs was assessed with a standardized interview: unconsciousness, confusion, amnesia, unsteadiness, bilateral leg weakness, blurred vision, nonrotatory dizziness, and paresthesias. The occurrence of TNAs was related to the presence of lacunes or white matter hyperintensities (Fazekas score, ≥2; early confluent or confluent lesions) in logistic regression analysis, adjusted for age, sex, and hypertension. Results- Of 304 participants (60% men; mean age, 67±9 years), 63 participants (21%) experienced ≥1 TNAs. Lacunes and early confluent or confluent white matter hyperintensities were more common in participants with TNAs than in participants without TNAs (35% versus 20%; adjusted odds ratio, 2.32 [95% CI, 1.22-4.40] and 48% versus 27%; adjusted odds ratio, 2.65 [95% CI, 1.44-4.90], respectively). Conclusions- In our study, TNAs are associated with the presence of lacunes and early confluent or confluent white matter hyperintensities of presumed vascular origin, which indicates that cerebral small vessel disease might play a role in the pathogenesis of TNAs.

BACKGROUND: The objective of this study was to evaluate differences in tolerability in patients with metastatic castration-resistant prostate cancer treated with enzalutamide (ENZA) or abiraterone acetate plus prednisone (AA+P). PATIENTS AND METHODS: This was a phase IV, prospective, open-label, multicenter, real-world study. Patients were prescribed ENZA or AA+P at the treating physician's discretion. Computerized tests of 4 cognitive domains (Cogstate), patient-reported outcomes (European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 [EORTC QLQ-30], Functional Assessment of Chronic Illness Therapy-Fatigue [FACIT-Fatigue], Functional Assessment of Cancer Therapy-Cognitive Function [FACT-Cog]), and patient/caregiver surveys were assessed at baseline and 2 months. Safety data were collected. RESULTS: Of 100 treated patients, 92 were evaluable (46/arm). Baseline characteristics were similar, with mild cognitive impairment observed in â¼20% of patients. The FACIT-Fatigue demonstrated a statistically significant worsening from baseline of -4.00 (95% confidence interval, -6.61 to -1.39) for ENZA compared with AA+P, -0.01 (95% confidence interval, -2.40 to 2.38). Overall, more adverse events (AEs) and more AEs of fatigue were reported with ENZA versus AA+P (52% vs. 36% and 26% vs. 8%, respectively). Grade 3/4 AEs were similar (4% vs. 6%). Unique neuropsychiatric AEs reported with ENZA included amnesia, cognitive disorders, memory impairment, and confusional state; those for AA+P included cerebrovascular accident, presyncope, and spinal cord compression. Clinically meaningful cognitive decline was seen in 4 patients on ENZA versus 1 patient on AA+P. However, the overall mean changes from baseline for the Cogstate tests, the EORTC QLQ-C30, and the FACT-Cog assessment were similar and showed no meaningful change. Caregiver survey responses noted more fatigue with ENZA and more moodiness with AA+P compared with patient responses. CONCLUSIONS: Although baseline values were similar, more fatigue and neurocognitive differences were observed with ENZA compared with AA+P.

OBJECTIVE: To evaluate the occurrences and to characterize the falling incidents of adult patients hospitalized in clinical and surgical units of a university hospital in the southern region of the country, in the period from 2011 to 2014. METHOD: Descriptive, cross-sectional and retrospective study, carried out from December 2016 to December 2017. The sample consisted of 1112 reports, covering all hospitalized patients who were notified with falls occurring in the studied period. Data were analyzed using descriptive and analytical statistics. RESULTS: Female and elderly patients were predominant in the sample, in which 69.4% of the incidents did not present any damage. The occurrence of falls was significantly higher at night. Limitation to walking and being unaccompanied were the most prevalent factors in the patient's conditions before the fall. CONCLUSION: The fall is a multifactorial event that requires periodic evaluation of the risk factors by the team to plan their prevention.

BACKGROUND: Delirium occurs commonly in older adults and is associated with adverse outcomes. Multicentre clinical trials evaluating interventions to prevent delirium are needed. The Confusion Assessment Method (CAM) is a validated instrument for delirium detection. We hypothesised it would be possible for a large feasibility study to train a large number of research assistants, with varying experience levels, to conduct CAM assessments reliably in multiple hospital sites. METHODS: A standardised training programme was followed, incorporating structured training at a central location and at study sites. CAM practice sessions on both delirious and non-delirious patients by research assistants were conducted and, thereafter, there was ongoing inter-rater reliability assessment on the CAM between research assistant pairs at study sites. The setting was eight acute care hospitals in England and Wales. Participants were research assistants working on a multicentre feasibility study of delirium prevention. The measurement used was the Confusion Assessment Method. RESULTS: Thirty-seven research assistants were trained in CAM assessment and 33 returned training logs. The logs showed there was 100% overall agreement between research assistant pairs on 295 CAM assessments, of which 263 (89.2%) were negative for delirium and 32 (10.8%) were positive. In the course of the feasibility study, research assistants successfully completed 5065 (89.7%) of the 5645 expected CAM assessments, with minimal missing data. CONCLUSION: Using the training methods described in this study, it is possible to achieve high quality delirium assessments for large numbers of patients with little missing data across geographically dispersed sites in multicentre studies. The standardisation of multisite delirium assessments is an important contribution to research methodology, and provides a much-needed advance for the field.

INTRODUCTION: Faced with the increasing number of pharmaceutical products on the market, several pharmacovigilance notifications regarding confusion between look-alike and sound-alike drugs have been reported. This study of perception among patients, family physicians and pharmacists aims to evaluate drug identification factors and the risk of errors of confusion for patients. MATERIAL AND METHODS: Patients were systematically approached in randomly selected pharmacies within the Midi-Pyrénées region in France and invited to complete a questionnaire. Two other questionnaires were respectively sent to family physicians and pharmacists in the same region asking for their opinion on patients' perception of the identification of prescribed medicines. RESULTS: Of the 768 patients interviewed, most report identifying their medications by name (brand name: 50%; generic: 21%), while a smaller number cite physical appearance (box: 16%, tablet: 7% and blister packaging: 3%). In practice the factors considered most likely to cause confusion by patients relate to drug appearance (look-alike tablets: 28%, look-alike boxes: 20% and look-alike blister packaging: 13%). In contrast, look-alike and sound-alike names (generic and brand names combined) were cited in 31% of cases. Physicians (n=345) and pharmacists (n=198) understimate that patients identify their treatment by name (physicians: 46%; pharmacists: 26% vs. patients: 71%), reporting instead that problems arise mainly from the appearance of medicines (physicians: identification: 52% and risk factors for confusion: 74%; pharmacists: identification: 74% and risk factors for confusion: 83%; versus patients: identification: 26%; risk factors for confusion: 61%). DISCUSSION: Our study highlights the critical role of medication name in identifying drugs among patients. However, confusion of look-alike tablets or pills figures prominently among fears surrounding medication errors. Despite several notifications of pharmacovigilance, this issue appears to be underestimated within the body of medical literature. Proper identification of medicines by patients is essential to improving medication safety and therapeutic compliance. Concrete measures can be undertaken to reach this goal.

BACKGROUND: Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is an established treatment for patients with Parkinson disease. One adverse event is the development of postoperative confusion. The aim of this study was to report the incidence and associated factors of postoperative confusion after STN DBS surgery. METHODS: This was a retrospective cohort study by chart review of patients with Parkinson disease who underwent STN DBS in a Brazilian public academic hospital from January 2013 to October 2017. The primary outcome was the incidence of postoperative confusion. The association of the outcome and imaging and clinical variables was evaluated. RESULTS: Among 49 patients who underwent STN DBS for Parkinson disease, the incidence of postoperative confusion was 26.5% (95% confidence interval 15%-41.1%). Univariate analysis identified the following variables associated with development of confusion: age (63.2 ± 7.8 years vs. 55.4 ± 9.1 years, P = 0.009), disease duration (16.5 ± 5.1 years vs. 13.2 ± 4.2 years, P = 0.027), Charlson comorbidity index (2 [interquartile range 1-3] vs. 1 [0-1 interquartile range], P = 0.002), width of the third ventricle (5.4 ± 2.1 mm vs. 4 ± 1.6 mm, P = 0.018), and cella media index (5 ± 1 vs. 5.6 ± 0.8, P = 0.018). After adjustment, Charlson comorbidity index remained significant (adjusted relative risk 1.64, 95% confidence interval 1.17-2.3, P = 0.004). CONCLUSIONS: The incidence of postoperative confusion in this cohort was 26.5%. After analysis of confounding factors, the Charlson comorbidity index was significantly associated with postoperative confusion.

El delirio es un síndrome neuropsiquiátrico, caracterizado por un trastorno agudo de la atención y de la cognición, de etiología multifactorial. Tiene una elevada prevalencia en la población mayor y se trata de un indicador de mal pronóstico. Incita a un impacto negativo, conduciendo a un deterioro de la calidad de vida de la persona. Objetivos: Identificar las intervenciones de enfermería dirigidas al adulto/ mayor hospitalizado, para el control del delirio. Metodología: Utilizando como referencia una cuestión PICO, se ha realizado la revisión de artículos publicados entre 2012 y 2017, que identificaron las intervenciones de enfermería dirigidas a la persona adulta/mayor hospitalizada presentando delirio. Resultados: Se identificaron 5 estudios en esta revisión bibliográfica que presentan estrategias dinámicas, de carácter preventivo y tendencialmente no farmacológicas, ante el delirio. Esto evidencia el papel del enfermero en el desempeñar acciones de prevención (dirigidas preferentemente a los factores de riesgo desencadenantes de esta alteración neurológica), en el mantenimiento del equilibrio sensorial, gestión del ambiente, nutrición/alimentación adecuadas, monitorización del dolor, sueño y fomentando la movilidad precoz. Conclusión: El abordaje ante al delirio debe incluir la identificación de factores predisponentes, precipitadores y el recurso a acciones adecuadas, con el fin de la resolución del cuadro. La investigación es imperativa en el sentido de reconocer y validar, qué acciones permiten controlar (prevenir/tratar) el delirio y, de esta forma, disminuir sus consecuencias
O delirium é uma síndrome neuropsiquiátrica, caracterizada por um transtorno agudo da atenção e cognição de etiologia multifactorial. Tem uma elevada prevalência na população idosa e trata-se de um indicador de mau prognóstico. Incita a um impacto negativo, conduzindo à deterioração da qualidade de vida da pessoa. Objetivos: Identificar as intervenções de enfermagem, dirigidas ao adulto/idoso hospitalizado, para o controlo do delirium. Metodologia: Utilizando como referência uma questão PICO, realizou-se a revisão de artigos publicados entre 2012 e 2017, que identificaram quais as intervenções de enfermagem dirigidas à pessoa adulta/idoso, hospitalizada apresentando delirium. Resultados: Identificaram-se 5 estudos nesta revisão bibliográfica que apresentam estratégias dinâmicas, de carácter preventivo e tendencialmente não farmacológicas, perante o delirium. Tal, evidencia o papel do enfermeiro em desempenhar acções de prevenção (dirigidas essencialmente, aos fatores de risco desencadeantes desta alteração neurológica) na manutenção do equilíbrio sensorial, gestão do ambiente, nutrição/hidratação adequadas, monitorização da dor, sono e estimulação da mobilidade precoce. Conclusão: A intervenção face ao delirium, deve incluir a identificação de fatores predisponentes, precipitantes e o recurso a acções adequadas, visando assim a resolução do quadro. A investigação torna-se imperativa, no sentido de reconhecer e validar quais as acções, que permitem controlar o delirium(prevenir/tratar) e desta forma diminuir as suas consequências
Delirium is a neuropsychiatric syndrome, characterized by an acute attention and cognition deficit disorder, of multifactorial etiology. It has a high prevalence in the elderly population and its an indicator of a poor prognosis. It leads to a negative impact, provoking deterioration in the person's quality of life. Objectives: This study aimed to identify the nursing interventions directed to the hospitalized adult / elderly, for the control of delirium. Methodology: Using a PICO question as a reference, a review of articles published between 2012 and 2017 was carried out. That identified, which nursing interventions aimed at the adult / elderly person hospitalized with delirium. Results: In this bibliographic review 5 studies were selected, in common, they present tendentially, non-pharmacological dynamic strategies of preventive character towards the delirium. This evidences the role of nursing in carrying out preventive actions (preferentially directed to risk factors, which may trigger this neurological alteration), such as the maintenance of the sensorial balance, assessing the local environment, monitoring pain, sleep and the stimulation of the early mobility. Conclusion: The interventions for delirium should include the identification of predisposing and precipitating factors with adequate actions, for its resolution. Research is imperative, to recognize and validate witch interventions may control delirium (prevent/ treat) and thus reduce its consequences
