Evaluate Department of Defense (DoD) antimicrobial stewardship programs (ASPs) by assessing the relationship between key clinical outcome metrics (antibiotic use, incidence of resistant pathogens, and incidence of Clostridioides difficile infections) and CDC Core Element (CE) adherence.
Design:
Retrospective, cross-sectional study of DoD hospitals in 2018 and 2021
Methods:
National Healthcare Safety Network Standardized Antimicrobial Administration Ratios (SAARs) were used to measure antibiotic use and microbiology results to evaluate four types of pathogen incidence. A novel CE scoring approach used scores to quantitatively assess relationships with CE adherence and outcome metrics using correlation and regression models. Assessments were repeated with 2021 data for Priority CE adherence and to conduct adjusted regressions for CEs and Priority CEs controlling for categorical bed size.
Results:
Compared to 2022 national data, DoD hospitals in 2021 had a similar proportion of facilities with a SAAR statistically significantly > 1.0. Leadership, Action, and Tracking CEs followed a more normal score distribution, while Reporting and Education were somewhat left-skewed. Unadjusted models often showed a positive relationship with higher CE scores associated with worse outcomes for the SAAR and pathogen incidence. Adjusted models indicated that procedural CEs, particularly Priority Reporting, were associated with better ASP-related outcomes.
Conclusions:
CEs should be more quantitatively assessed. Results provide initial evidence to prioritize procedural CE implementation within the DoD; however, additional investigation for structural CEs is needed. Patient outcome data should be collected as an important indicator of ASP performance.
Characterization and assessment of Department of Defense’s (DoD’s) Antibiotic Stewardship Programs (ASPs) to determine adherence to Centers for Disease Control and Prevention (CDC) Core Elements and compare to national adherence
Design:
Retrospective, observational with supplemental survey
Methods:
Facility characteristics and CDC Core Elements (CE) adherence data for 2017–2021 were retrieved from the National Healthcare Safety Network’s (NHSN) annual hospital survey with DoD data from the Defense Health Agency and national data from the Antibiotic Resistance and Patient Safety Portal. An online supplemental survey was administered to DoD hospitals. Descriptive statistics and bivariate analyses were completed for facility characteristics and supplemental survey questions to determine correlations between variables. A framework analysis compared DoD ASPs to CEs and Priority Elements.
Results:
Supplemental surveys were completed for 85.1% of DoD’s hospitals. DoD’s hospitals were smaller on average than national hospitals. ASP leaders were assigned more often than volunteer and typically served in the role for less than four years. Staffing mix differed, with more equivalent proportions of civilian/contractor to military at larger hospitals in the U.S. Most DoD ASPs consisted of ≤ 25% pharmacists. ASP leaders were largely available on a daily basis; pharmacist leaders spent more time on ASP activities than physicians. CE adherence was high, but in 2021 DoD lagged national adherence in the structural CEs of Leadership, Accountability, and Pharmacy Expertise.
Conclusions:
DoD hospitals lagged in national adherence to the structural CEs, presenting opportunities for ASP improvement. Refinement of CE adherence measurements, coupled with impact on health outcomes, could aid in better-identifying areas for improvement.
A number of studies have demonstrated that hyperthyroidism increases the prevalence of psychiatric disorders and the likelihood of depressive symptoms, anxiety and hipomania. Apathetic hyperthyroidism is a syndrome, which presents with symptoms of depression, apathy, somnolence or pseudodementia in the absence of the usual symptoms and signs of hyperthyroidism. This condition is more common in the elderly although it has also been described in young adults and adolescents.
In the majority of cases, treatment of hyperthyroidism results in an improvement in neuropsychiatric manifestations in parallel with an improvement of psychical (somatic?) symptoms and psychotropic medication is deemed unnecessary.
Approximately one-third of patients with Graves’ hyperthyroidism are prescribed psychotropic drugs. Sometimes to treat mental symptoms like psychosis or severe agitation, sometimes to treat mental symptoms remaining after amelioration of hyperthyroidism, and sometimes when the diagnosis of Graves’ hyperthyroidism has been missed and the patient is treated as having a primary psychiatric disorder.
Objectives
To present a case of a patient with neuropsychiatric symptoms caused by thyroid dysfunction.
Methods
Case presentation and non-systematic review of existing literature on Pubmed using the following keywords: hyperthyroidism, psychiatric disorders, psychiatric symptoms, depression, psychosis.
Results
We report the case of a 21-year-old female without history of psychiatric illness who presented to the emergency department with somnolence, apathy, cognitive impairment (answering “I don’t know” to most questions), poverty of speech, abulia, perplexity and delusional belief of ruin, in addition to physical symptoms namely alopecia and weight loss. According to her father, she was very active and dynamic person until two days prior, when he started noticing growing apathy, leading to job absenteeism. Urine analysis for elicit drugs was negative.
Investigation for organic disease was undertaken and the blood analysis revealed overt hyperthyroidism.
She was initially treated with aripiprazol. After thyroid dysfunction was identified, she was evaluated by an endocrinologist and started treatment with tiamazol and propanolol, presenting gradual remission of the psychiatric changes. Aripiprazole was discontinued and she was reevaluated in psychiatry consultation after about a month, with complete remission of psychiatric manifestations and normalized thyroid function.
Conclusions
Neuropsychiatric manifestations of thyroid dysfunction are often misdiagnosed as a primary psychiatric disorder. It is necessary to optimize the medical management of these patients in whom the psychiatric symptoms masks a curable organic cause.
This cross-sectional study employs structural equation modelling (sEM) to explore both direct and indirect effects of parental level of education and child individual factors on the length-for-age outcomes in children aged 6–24 months assisted by the Bolsa Família Program in the State of Alagoas. A total of 1448 children were analysed by the sEM technique. A negative standardised direct effect (sDE) of the children’s younger age (sDE: −0·06; P = 0·017), the use of bottle feeding (sDE: −0·11; P < 0·001) and lack of a minimum acceptable diet (sDE: −0·09; P < 0·001) on the length-for-age indicator was found. Being female (SDE: 0·08; P = 0·001), a higher birth weight (SDE: 0·33; P < 0·001), being ever breastfed (sdE: 0·07; P = 0·004) and a higher level of parental education (SDE: 0·09; P < 0·001) showed a positive SDE effect on the child’s length-for-age. The model also demonstrated a negative standardised indirect effect (SIE) of the sweet beverage consumption (SIE: −0·08; P = 0·003) and a positive effect of being ever breastfed (SIE: 0·06; P = 0·017) on the child’s length-for-age through parental level of education as a mediator. This research underscores the crucial role of proper feeding practices and provides valuable insights for the development of targeted interventions, policies and programmes to improve nutritional well-being and promote adequate linear growth and development among young children facing similar challenges.
The mycosis histoplasmosis is also considered a zoonosis that affects humans and other mammalian species worldwide. Among the wild mammals predisposed to be infected with the etiologic agent of histoplasmosis, bats are relevant because they are reservoir of Histoplasma species, and they play a fundamental role in maintaining and spreading fungal propagules in the environments since the infective mycelial phase of Histoplasma grows in their accumulated guano. In this study, we detected the fungal presence in organ samples of bats randomly captured in urban areas of Araraquara City, São Paulo, Brazil. Fungal detection was performed using a nested polymerase chain reaction to amplify a molecular marker (Hcp100) unique to H. capsulatum, which revealed the pathogen presence in organ samples from 15 out of 37 captured bats, indicating 40.5% of infection. Out of 22 Hcp100-amplicons generated, 41% corresponded to lung and trachea samples and 59% to spleen, liver, and kidney samples. Data from these last three organs suggest that bats develop disseminated infections. Considering that infected bats create environments with a high risk of infection, it is important to register the percentage of infected bats living in urban areas to avoid risks of infection to humans, domestic animals, and wildlife.
Supplementing embryonic culture medium with fetal bovine serum (FBS) renders this medium undefined. Glucose and growth factors present in FBS may affect the results of cell differentiation studies. This study tested the hypothesis that FBS supplementation during in vitro culture (IVC) alters cell differentiation in early bovine embryo development. Bovine embryos were produced in vitro and randomly distributed into three experimental groups at 90 h post insemination (90 hpi): the KSOM-FBS group, which consisted of a 5% (v/v) FBS supplementation; the KSOM33 group, with the renewal of 33% of medium volume; and the KSOM-Zero group, without FBS supplementation nor renewal of the culture medium. The results showed that the blastocyst rate (blastocyst/oocytes) at 210 hpi in the KSOM-FBS group was higher than in the KSOM-Zero group but not different from the KSOM33 group. There were no significant changes in metabolism-related aspects, such as fluorescence intensities of CellROX Green and MitoTracker Red or reduced nicotinamide adenine dinucleotide (NADH) and flavin adenine dinucleotide (FAD+). Immunofluorescence analysis of CDX2 revealed that the lack of FBS or medium supplementation reduced the number of trophectoderm (TE) cells and total cells. Immunofluorescence analysis revealed a reduction of SOX17-positive cell numbers after FBS supplementation compared with the KSOM33 group. Therefore, we concluded that FBS absence reduced blastocyst rates; however, no reduction occurred when there was a 33% volume renewal of the medium at 90 hpi. We also concluded that FBS supplementation altered TE and primitive endoderm cell allocation during early bovine embryo development.
Delusional disorder (DD) is a psychotic disorder with an estimated prevalence of less than one percent,traditionally characterized by systematized delusional ideas with no cognitive deterioration.However, some studies have been reporting impairment of neurocognitive system (social cognition,learning and memory, expressive language,complex attention, executive function) that might have an impact functionality both in social and work domains..
Objectives
This work aims to review clinical evidence on self-perceived functional impairment or disability in DD and to present two clinical cases evaluated at a psychiatric unit.
Methods
We report two clinical cases based on patients’ history and clinical data, and reviewed clinical records using PubMed® database with search terms of “Delusional Disorder”,“Cognition Impairment in Persistent DD”.
Results
We present two clinical cases of patients who were admitted to psychiatric unit after developing psychotic symptoms namely persecutory delusions about neighbors.A persistent delusional disorder was established and antipsychotic treatment was initiated.The 74-years-old men presented deficits in executive and memory processes; ended up institutionalized after two months of being discharged.The 47-years-old woman, despite remaining as a lawyer, noticed a decrease in work capacity and so she ended up being responsible for less demanding cases.Cases of delusional disorder showed a poor performance in most cognitive tests and some of the cognitive deficits seem to affect functionality namely memory, expressive language and attention.
Conclusions
Although classical literature has not systematized an association between DD and personality deterioration,there are some evidences of loss of functionality and cognitive commitment in this disorder.This suggests the importance of cognitive interventions to improve functional prognosis in this clinical population.
Dissociative seizures (DS) are classified as dissociative convulsions within the group of dissociative disorders. Although they share many features with epileptic seizures (ES), they are not a consequence of abnormal brain discharges and may be related to psychogenic causes. DS represent a common diagnostic and are often confounded with ES.
Objectives
The aim of this study is to review the current evidence about the differential diagnosis between DS and ES.
Methods
We conducted a non-sytematic review on the topic, using Pubmed/Medline database.
Results
Studies emphasize a correct diagnosis before treatment of seizures. DS and ES respond differently to anticonvulsant medication and early or incorrect prescription of can even exacerbate DS. Clinical features and a neuropsychiatric history can also help. The presence of a dissociative “stigmata”, such as unexplained sensory loss, may support a non-epileptic diagnosis. EEG videorecording method is the gold standard diagnosis for DS, however often displays rhythmic movement artifacts that may resemble seizure activity and confound the interpretation. The absence of ictal EEG discharges characteristic of epilepsy is a sign of DS. However, this may not be true for some partial ES, particularly those from temporal lobes, whom also tend to report shorter duration of seizures, whereas patients with DPD often describe experiences lasting for hours or longer.
Conclusions
Distinguish DS from ES can be challenging. However, there are features that can help in the differential diagnosis. A correct diagnosis is essential for an adequate therapeutic approach, better prognosis, reduction of medical costs and also a referral to the right medical specialty.
The objective of this study is to provide approaches to determine the mature weight of intact male hair sheep using body composition data. To estimate empty body weight (EBW) at maturity, we used information from eight independent studies comprising a total of 250 intact males in growing and finishing phases. The quantitative data used for each animal were body weight (BW), EBW, water-free EBW protein content, water-free EBW fat content, water-free EBW ash content and EBW water content. The water, protein, fat and ash contents in the EBW and water-free EBW were predicted by non-linear regressions. The best model was chosen considering the achievement of convergence and capacity for biological explanation. The standard deviation of the asymptotic EBW was computed using a simulation method based on a Monte Carlo approach. Among the non-linear evaluations, only the allometric function converged with the parameters within the expected biological limits. To estimate mature EBW, only protein and fat were suitable to predict estimates with the capacity to biological explanation. The water and protein contents in the EBW were closely associated. Animal maturity can be estimated mathematically using body composition. Maturity was reached at an EBW of 47.3 and 57.5 kg when protein and fat were used as a predictor, respectively. We conclude that protein is a good predictor of maturity for intact male hair sheep.
This study aimed to verify the association between socio-economic and demographic characteristics and dietary patterns (DP) of children assisted by the Conditional Cash Transfer Program, Bolsa Família Program (BFP).
Design:
This is a cross-sectional study. DP were defined using a principal component analysis. The association of the predictive variables and DP was modelled using multilevel linear regression analysis.
Setting:
This study was conducted in six municipalities from the State of Alagoas, Brazil.
Participants:
The participants were children aged 6–24 months who were assisted by the BFP.
Results:
A total of 1604 children were evaluated. Four DP were identified (DP1, DP2, DP3 and DP4). DP1 is composed of traditional Brazilian food. DP2 is formed mostly from ultra-processed foods (UPF). DP3 consists of milk (non-breast) with added sugar, while DP4 consists of fresh and minimally processed foods. Caregivers with higher age and education (β = −0·008; (95 % CI −0·017, −0·000); β = −0·037; (95 % CI −0·056, −0·018), respectively) were negatively associated with DP2. We observed a negative association between households with food insecurity (β = −0·204; (95 % CI −0·331, −0·078)) and DP4 and a positive association between caregivers with higher age and education (β = 0·011; (95 % CI (0·003; 0·019); β = 0·043; (95 % CI 0·025, 0·061), respectively) and DP4.
Conclusion:
This study identified the association between socio-economic inequities and DP early in life, with an early introduction of UPF, in children assisted by BFP in the State of Alagoas.
Digital Mental Health holds strategic potential in fulfilling populations’ mental healthcare unmet needs, enabling convenient and equitable access to mental healthcare. However, despite strong evidence of efficacy, uptake by mental healthcare providers remains low and little is known about factors influencing adoption and its interrelationship throughout the Digital Mental Health adoption process.
Objectives
This study aimed at gaining in-depth understanding of factors influencing adoption and mapping its interrelationship along different stages of the Digital Mental Health adoption process.
Methods
This work adopted a qualitative approach consisting of in-depth semi-structured interviews with 13 mental healthcare professionals, including both psychologists and psychiatrists. The interviews were transcribed and analysed thematically, following Braun and Clarke’s method.
Results
In this communication, we will describe how digital technology is currently used by clinicians to deliver mental healthcare. We identify potential factors influencing Digital Mental Health adoption and characterize the different identified stages inherent to this appropriation process: i) Pondering appropriate use; ii) Contractualizing the therapeutic relationship; iii) Performing online psychological assessment; iv) Adapting and/or developing interventions; v) Delivering Digital Mental Health interventions; and vi) Identifying training unmet needs. A discussion on how different factors and its interrelationship impact the adoption process will also be performed.
Conclusions
By characterizing mental healthcare providers journey throughout the Digital Mental Health adoption process, we intend to inform ecosystem stakeholders, such as researchers, policy makers, societies and industry, on key factors influencing adoption, so policies, programs and interventions are developed in compliance with this knowledge and technology is more easily integrated in clinical practice.
Rates of cannabis use among pregnant women have been increasing. Psychiatrists may be required to provide counselling regarding marijuana use in pregnancy for their patients.
Objectives
To produce an up-to-date review of cannabis effects on pregnancy and the offspring.
Methods
We performed a non-systematic review of the literature apropos a clinical case.
Results
A 31-years-old, 22-weeks pregnant woman presented with severe anxiety, panic attacks and insomnia which she managed solely with cannabis. She had been previously treated with antidepressants and benzodiazepines with symptom remission but had suspended before her pregnancy without medical advice. She believed medication was more harmful to the baby than her cannabis use. There is little perception of risk concerning cannabis use in pregnant woman. Information on cannabis use is less likely to be obtained from healthcare providers than from anecdotal experiences, Internet searching and advice from friends and family. Prenatal use of cannabis has been associated with anaemia in the mother, whereas in the offspring it is associated with reduction in birth weight and greater likelihood of placement in intensive care units. There is insufficient evidence to support an association between marijuana use and any specific congenital abnormality, but also to demonstrate its safety.
Conclusions
It is essential for psychiatrists to have up-to-date knowledge of the effects of cannabis on the pregnancy and the offspring to properly counsel their patients. However, the effects of cannabis on maternal and foetal outcomes remain generally unknown. With rising numbers of female users, there is urgent need for further research.
The mental health impact of the COVID-19 pandemic is well documented. Portugal entered the emergency state on 19th march due to rising numbers of infected patients. The emergency state introduced regulatory measures that restricted people’s movements, applied a curfew, and closed most non-essential spaces and activities, such as shops and religious celebrations.
Objectives
To evaluate the rates of suicides during the emergency state in Portugal.
Methods
We obtained the number of probable suicides during 19th march and 2nd may 2020, 2019 and 2018 from SICO/eVM (Real Time Mortality Electronic Surveillance). This system is used for health planning in Portugal and provides provisory data which is updated every 10 minutes. ExcelÒ was used for the statistical analysis.
Results
During the Emergency State in Portugal there were 57 probable suicides. Comparing to the same period in 2018 and 2019, there were 62 and 70 probable suicides, respectively. Social isolation, anxiety, fear of contagion, chronic stress, and economic difficulties may lead to the development or exacerbation of depressive, anxiety, substance use, and other psychiatric disorders. Literature on suicides due to COVID-19 mention not only fear of infection, but also social isolation and distancing and economic recession as causes for suicide attempts and completions.
Conclusions
During the emergency state there was not an increase of probable suicides, compared to previous years. The greater vigilance of people’s movements may have deterred many attempts. However, policymakers and health care providers must be alert as the current psychosocial predispose to an increase in suicide rates.
Psychosis it is a serious medical condition that could happen to anyone while travelling, even without a prior history of mental illness. Some psychotic episodes during travel likely are brief psychotic disorders. This is a poorly understood subject that seems to have an increasing incidence.
Objectives
This work aims to present a clinical case of a patient who developed psychotic symptoms on her visit to China, and to provide a brief update review of this subject.
Methods
We describe a case based on patient’s history and clinical data. We also searched and reviewed cases on “travel” AND “psychosis” and “tourist” AND “psychosis” using PubMed® database.
Results
We report the case of a 41-year-old woman without psychiatric antecedents or substance use who developed psychotic symptoms during a travel to China. Symptoms resolved completely soon after returning to Portugal and admission to the psychiatric emergency service where an antipsychotic treatment was initiated. Psychosis in tourists typically occur in destinations with strong symbolic or mystical connotations and in individuals who travel alone for several days. The most common symptoms are hallucinations, delusions, ideas of reference and agitation. Most patients improved and returned to previous functioning.
Conclusions
To improve the knowledge of travel-related psychosis it is important to identify the cases and the associated biological and clinical factors, later on it may be possible to identify the predictive factors of these psychosis. Further research are necessary to establish a possible association between brief psychotic episode and travel to China, as reports for tourists to Jerusalem and to Florence.
To evaluate the association between Fe deficiency anaemia (IDA) and complementary feeding in children under 2 years old assisted by the Conditional Cash Transfer programme, Bolsa Família (BFP).
Design:
Cross-sectional study. Data were obtained through a standardised form, questionnaire to assess the eating habits of children under 2 years of age, capillary Hb (HemoCue®) and the Brazilian Household Food Insecurity Measurement Scale. Associations were calculated using hierarchical Poisson regression, adjusted at the last level by socio-economic, demographic and environmental variables from previous hierarchical levels.
Setting:
Six municipalities from the State of Alagoas, Brazil.
Participants:
Children aged 6–24 months assisted by BFP.
Results:
A total of 1604 children were evaluated, among whom 58·1 % had anaemia. A higher number of food groups consumed (prevalence ratio (PR) = 0·97; 95 % CI 0·95, 0·99; P = 0·009), the consumption of dairy (PR = 0·86; 95 % CI 0·79, 0·84; P = 0·001) and meat (PR = 0·90; 95 % CI 0·83, 0·99; P = 0·030) in addition to bottle feeding (PR = 0·88; 95 % CI 0·82, 0·96; P = 0·004) were associated with a lower prevalence of IDA.
Conclusions:
IDA is still a serious public health problem in children under 2 years old assisted by BFP in Alagoas. We highlight the importance of promoting complementary feeding based on a diversified dietary intake, as well strengthening prophylactic supplementation programmes to increase children’s adherence in conjunction with the implementation of food and nutrition education to help reduce the prevalence of this condition.
To evaluate the association between the consumption of ultra-processed foods (UPF) and the practice of breast-feeding in children under 2 years of age assisted by the conditional cash transfer programme, Bolsa Família Programme (PBF).
Design:
A cross-sectional study. The consumption of UPF and the practice of breast-feeding were assessed using a structured 24-h recall. Associations were calculated using hierarchical Poisson regression, adjusted at the last level by socio-economic, demographic and environmental variables from previous hierarchical levels.
Setting:
Six counties from the state of Alagoas, Brazil.
Participants:
Children aged 6−24 months, assisted by PBF.
Results:
A total of 1604 children were evaluated, 11·7% of whom were overweight, and most had consumed UPF (90·6%) in the last 24 h. The most consumed UPF were biscuits, chocolate milk and baby food with 74·8, 66·8 and 24·9%, respectively. Through multivariable analysis, an association was found between lower consumption of UPF in the continuation of breast-feeding until the second year of life (prevalence ratio (PR) 0·91, 95 % CI 0·86, 0·96) and in the first year of life (PR 0·93, 95 % CI 0·88, 0·99).
Conclusions:
It was found that the studied population had a high consumption of UPF, which harmed continued breast-feeding. We highlight the importance of strengthening public policies aimed at the promotion, protection and support of breast-feeding and healthy complementary feeding aimed at populations that have difficulties in physical and economic access to a healthy and adequate diet.
Wild poinsettia (Euphorbia heterophylla L.) is a troublesome broadleaf weed in grain production areas in South America. Herbicide resistance to multiple sites of action has been documented in this species, including protoporphyrinogen oxidase (PPO) inhibitors. We investigated the physiological and molecular bases for PPO-inhibitor resistance in a E. heterophylla population (RPPO) from Southern Brazil. Whole-plant dose–response experiments revealed a cross-resistance profile to three different chemical groups of PPO inhibitors. Based on dose–response parameters, RPPO was resistant to lactofen (47.7-fold), saflufenacil (8.6-fold), and pyraflufen-ethyl (3.5-fold). Twenty-four hours after lactofen treatment (120 g ha−1) POST, RPPO accumulated 27 times less protoporphyrin than the susceptible population (SPPO). In addition, RPPO generated 5 and 4.5 times less hydrogen peroxide and superoxide than SPPO, respectively. The chloroplast PPO (PPO1) sequences were identical between the two populations, whereas 35 single-nucleotide polymorphisms were found for the mitochondrial PPO (PPO2). Based on protein homology modeling, the Arg-128-Leu (homologous to Arg-98-Leu in common ragweed [Ambrosia artemisiifolia L.] was the only one located near the catalytic site, also in a conserved region of PPO2. The cytochrome P450 monooxygenase inhibitor malathion did not reverse resistance to lactofen in RPPO, and both populations showed similar levels of PPO1 and PPO2 expression, suggesting that metabolic resistance and PPO overexpression are unlikely. This is the first report of an Arg-128-Leu mutation in PPO2 conferring cross-resistance to PPO inhibitors in E. heterophylla.
Memantine, an aminodamantane, is an non-competitive NMDA receptor antagonist with strong voltage-dependence and fast kinetics. Unlike other drugs used to treat Alzheimer's disease, memantine blocks NMDAR channels in a concentration, time and voltage-dependent fashion. Previous results of our group evidenced a correlation of PLA2 inhibition activity and the severity of clinical aspects of Alzheimer's disease. Besides, in rat, the activity of PLA2 is required for memory retrieval and the inhibition of this activity in hippocampus was reported to impair memory acquisition. In mammalians, this important gene family is composed of >30 genes dispersed in throughout the genome in almost every chromosome. These genes code for a large number of proteins that can be divided into five main enzymatic subgroups. After screening for PLA2 genes expressed in the brain, using in silico databases, we investigated if these genes were modulated by memantine. For this wistar rats received memantine by gavage for a period of 30 days. After treatment the animals were sacrificed and mRNA samples of hippocampus and frontal cortex were used for quantification of Pla2 genes using qRT-PCR. The expression of specific Pla2 genes was significantly increased in both tissues evaluated. Our data does not prove that memantine has a direct effect over PLA2, however, we could demonstrate that PLA2 expression is activated after treatment with this drug. This information may be relevant to clarify its mechanism of action on both aspects: neuroprotection and reverse deficits in learning/memory.
A significant proportion of elderly patients admitted to the medical wards have psychiatric comorbidities, such as delirium, depression or dementia. Frequently they develop cognitive changes during the hospitalization which constitute an important motive of referral to psychiatric services. The MMSE is considered a useful way to document cognitive impairments.
Objective
The aim of this study is to evaluate the capacity of MMSE to detect cognitive changes in elderly subjects referenced for liaison psychiatry service.
Methods
Observational study developed between October of 2011 and July of 2013. Included subjects with 65 years and older hospitalized in Internal Medicine service referenced for old age liaison service. Each patient was analyzed according to: social demographic characteristics, medical and psychiatric comorbidities and clinical severity. MMSE was applied to all patients.
Results
Of all 143 patients observed about 30% were referenced because of cognitive changes. Of the total, 46% didn’t collaborate in MMSE. These patients were diagnosed with delirium (52%), delirium superimposed with dementia (17%), depression (12%), adjustment disorder (6%), dementia (3%), psychosis (3%) and others (7%). The main reasons of uncooperativeness, with exception of disturb of conscience and/or attention deficits were: visual difficulties (50%), motor difficulties, physical restraints, distracting environment, duration and extension of the exam and anxiety and/or depressive symptoms.
Conclusions
The cognitive assessment of elderly subjects with MMSE in medical settings is compromised by many aspects, including the inherent characteristics of the clinical environment. A more useful, practical and applicable test is needed to evaluate this specific population.
Previous epidemiological studies clearly demonstrated gender differences in the patterns of mental illness. as a matter of fact, female suffer more from depressive and anxiety disorders, while male suffer more from addictive behaviour and psychotic disorders.
Objectives/aims:
The present study was elaborated by the Psychiatric Department Quality Commission of the Coimbra University Hospital in order to identify gender differences in socio-demographic and clinical characteristics of patients that were hospitalized from January to June 2011.
Methods:
We analyzed 417 clinical files and gathered socio-demographic information (gender, age, marital status and job) and clinical information (diagnosis and hospitalization's length).
Statistical analysis was performed with SPSS program, using the chi-square's and Mann-Whitney's tests.
Results:
53% of the inpatients were women.
It was also observed that women were older (p = 0.021), more frequently married and widowed (p < 0.001), were less associated with compulsory admission (p < 0.001), had shorter hospitalizations (p = 0.024) and were more often diagnosed with adjustment reaction and bipolar disorder (p < 0.001), while men were younger (p < 0.001), more frequently single (p < 0.001), more frequently unemployed (p < 0.001), were more subject to compulsory admission (p < 0.001) and were more often diagnosed with addictive disorders and schizophrenia.
Conclusions:
These results are consistent with the existing literature and enable us to organize the services’conditions according to the needs of our psychiatric inpatient population.
