Chronic Stress Alters Synaptic Inhibition/Excitation Balance of Pyramidal Neurons But Not PV Interneurons in the Infralimbic and Prelimbic Cortices of C57BL/6J Mice.

The medial prefrontal cortex (mPFC) plays a pivotal role in regulating working memory, executive function, and self-regulatory behaviors. Dysfunction in the mPFC circuits is a characteristic feature of several neuropsychiatric disorders including schizophrenia, depression, and post-traumatic stress disorder. Chronic stress (CS) is widely recognized as a major triggering factor for the onset of these disorders. Although evidence suggests synaptic dysfunction in mPFC circuits following CS exposure, it remains unclear how different neuronal populations in the infralimbic (IL) and prelimbic (PL) cortices are affected in terms of synaptic inhibition/excitation balance (I/E ratio). Here, using neuroproteomic analysis and whole-cell patch-clamp recordings in pyramidal neurons (PNs) and parvalbumin (PV) interneurons within the PL and IL cortices, we examined the synaptic changes after 21 d of chronic unpredictable stress, in male mice. Our results reveal distinct impacts of CS on PL and IL PNs, resulting in an increased I/E ratio in both subregions but through different mechanisms: CS increases inhibitory synaptic drive in the PL while decreasing excitatory synaptic drive in the IL. Notably, the I/E ratio and excitatory and inhibitory synaptic drive of PV interneurons remained unaffected in both PL and IL circuits following CS exposure. These findings offer novel mechanistic insights into the influence of CS on mPFC circuits and support the hypothesis of stress-induced mPFC hypofunction.

Postoperative Acute Kidney Injury After Intraoperative Hypotension in Major Risk Procedures.

Background Reportedly prevalent, intraoperative hypotension (IOH) is linked to kidney injury and increased risk of mortality. In this study, we aimed to assess IOH incidence in high-risk non-cardiac surgery and its correlation with postoperative acute kidney injury (PO-AKI) and 30-day postoperative mortality. Methodology This retrospective cohort study included adult inpatients who underwent elective, non-cardiac, high-risk European Society of Anaesthesiology/European Society of Cardiology surgery from October to November of 2020, 2021, and 2022, excluding cardiac, intracranial, or emergency surgery. IOH was primarily defined by the 2022 Anesthesia Quality Institute. PO-AKI was defined as an increase in serum creatinine ≥0.3 mg/dL within 48 hours, the need for dialysis in dialysis-naïve patients, or the documentation of AKI in clinical records. For univariate analysis, the Mann-Whitney U test and chi-square or Fisher's exact tests were performed, as appropriate. Logistic regression was used to test risk factors for IOH in univariate analysis (p < 0.1). The significance level considered in multivariate analysis was 5%. Results Of the 197 patients included, 111 (56.3%) experienced IOH. After adjustment, surgical time >120 minutes remained associated with higher odds of IOH (odds ratio (OR) = 9.62, 95% confidence interval (CI) = 2.49-37.13), as well as combined general + locoregional (vs. general OR = 3.41, 95 CI% = 1.38-8.43, p = 0.008; vs. locoregional OR = 6.37, 95% CI = 1.48-27.47). No association was found between IOH and 30-day postoperative mortality (p = 0.565) or PO-AKI (p = 0.09). The incidence of PO-AKI was 14.9% (27 patients), being significantly associated with higher 30-day postoperative mortality (p = 0.018). Conclusions Our study highlights the high prevalence of IOH in high-risk non-cardiac surgical procedures. Its impact on PO-AKI and 30-day postoperative mortality appears less pronounced compared to the significant implications of PO-AKI, emphasizing the need for PO-AKI screening and renal protection strategies.

Motor performance of Indian preterm infants as compared to the US population on the Test of Infant Motor Performance (TIMP).

PURPOSE: The study aimed at scoring Indian preterm infants at three months corrected age on the TIMP and then comparing the scores to the United States age-based population scores. METHODS: After obtaining Ethical clearance, participants meeting the inclusion criteria of 53 infants whose parents consented were screened and recruited (N = 47) at a tertiary care hospital. The TIMP was then administered at three months of corrected age. RESULTS: Data obtained from 47 infants born preterm (Male = 33, Female = 14) at three months corrected age with mean gestational age (34.4 ± 2.36 weeks) and mean birth weight (1.93 ± 0.55 kgs) was analyzed. Indian infants born preterm scored a mean of (98.17 ± 20.90) compared to the US mean of (108 ± 19), suggesting an under-performance. The average scores were lower when comparing the mean of the study group with the US-based age-matched population. CONCLUSION: Motor performance scores of Indian preterm infants were low when compared to their US counterparts. Since there exists a difference in the raw score obtained by Indian Preterm infants compared to the US-based population, it may not be appropriate to categorize the motor development of Indian infants based on the US population scores.

Needs of Family Caregivers of People with Lower Limb Amputations: A Scoping Review.

Lower limb amputation affects several parameters of a patient's life. Family caregivers providing care for these patients experience multiple feelings and needs; knowing caregivers' needs is essential to prepare them for this new role, as well as the health planning of this type of care. This scoping review aimed to identify and map the needs of family caregivers of people with lower limb amputations. This scoping review was conducted in accordance with the JBI methodological framework and the PRISMA-ScR reporting guidelines. A bibliographical search was carried out on the needs of family caregivers of lower limb amputees in 15 databases. Two independent reviewers extracted data using a data extraction tool developed for this scoping review. Eight studies were included in the present review (n = 6 quantitative studies; n = 2 reviews). Results indicate that family caregivers of people with lower limb amputations may experience an extensive range of needs, as follows: (i) mental health and psychological support, (ii) physical health, (iii) health and well-being, (iv) supportive care, (v) social support, and (vi) educational/informational support. The needs identified in this review can help to develop interventions and programs that provide better support during the situational transition process.

Copaiba oil minimizes inflammation and promotes parenchyma re-epithelization in acute allergic asthma model induced by ovalbumin in BALB/c mice.

Introduction: Asthma is a condition of airflow limitation, common throughout the world, with high mortality rates, especially as it still faces some obstacles in its management. As it constitutes a public health challenge, this study aimed to investigate the effect of copaiba oil (e.g., Copaifera langsdorffii), as a treatment resource, at doses of 50 and 100 mg/kg on certain mediators of acute lung inflammation (IL-33, GATA3, FOXP3, STAT3, and TBET) and early mechanisms of lung remodeling (degradation of elastic fiber tissues, collagen deposition, and goblet cell hyperplasia). Methods: Using an ovalbumin-induced acute allergic asthma model in BALB/c mice, we analyzed the inflammatory mediators through immunohistochemistry and the mechanisms of lung remodeling through histopathology, employing orcein, Masson's trichrome, and periodic acid-Schiff staining. Results: Copaiba oil treatment (CO) reduced IL-33 and increased FOXP3 by stimulating the FOXP3/GATA3 and FOXP3/STAT3 pathways. Additionally, it upregulated TBET, suggesting an additional role in controlling GATA3 activity. In the respiratory epithelium, CO decreased the fragmentation of elastic fibers while increasing the deposition of collagen fibers, favoring epithelial restructuring. Simultaneously, CO reduced goblet cell hyperplasia. Discussion: Although additional research is warranted, the demonstrated anti-inflammatory and re-epithelializing action makes CO a viable option in exploring new treatments for acute allergic asthma.

Social representations of tuberculosis by people with the disease.

OBJECTIVE: To understand the social representations of people with tuberculosis about the disease and its implications for following treatment. METHOD: A descriptive, qualitative study based on the Theory of Social Representations. It was conducted in a municipal health unit in the city of Belém. The participants were people diagnosed with tuberculosis and undergoing directly observed treatment, with the sample size defined by the data saturation technique. Data collection was done through semi-structured interviews. For data analysis it was used thematic content analysis. RESULTS: The records converged into three categories: Representations of tuberculosis and its impacts on the diagnosis; The faces of treatment: challenges facing follow-up and hope; and Constructions of living with the disease in family and society. FINAL CONSIDERATIONS: Living with the disease transforms everyday life and relationships. Discrimination and prejudice denote the need to reconfigure such representations for patients to be embraced.

Chronic treatment with D2-antagonist haloperidol leads to inhibitory/excitatory imbalance in striatal D1-neurons.

Striatal dysfunction has been implicated in the pathophysiology of schizophrenia, a disorder characterized by positive symptoms such as hallucinations and delusions. Haloperidol is a typical antipsychotic medication used in the treatment of schizophrenia that is known to antagonize dopamine D2 receptors, which are abundantly expressed in the striatum. However, haloperidol's delayed therapeutic effect also suggests a mechanism of action that may go beyond the acute blocking of D2 receptors. Here, we performed proteomic analysis of striatum brain tissue and found more than 400 proteins significantly altered after 30 days of chronic haloperidol treatment in mice, namely proteins involved in glutamatergic and GABAergic synaptic transmission. Cell-type specific electrophysiological recordings further revealed that haloperidol not only reduces the excitability of striatal medium spiny neurons expressing dopamine D2 receptors (D2-MSNs) but also affects D1-MSNs by increasing the ratio of inhibitory/excitatory synaptic transmission (I/E ratio) specifically onto D1-MSNs but not D2-MSNs. Therefore, we propose the slow remodeling of D1-MSNs as a mechanism mediating the delayed therapeutic effect of haloperidol over striatum circuits. Understanding how haloperidol exactly contributes to treating schizophrenia symptoms may help to improve therapeutic outcomes and elucidate the molecular underpinnings of this disorder.

Chronic stress promotes basal ganglia disinhibition by increasing the excitatory drive of direct-pathway neurons.

Chronic stress (CS) is a well-recognized triggering factor in obsessive-compulsive disorder (OCD) and Tourette's syndrome (TS), two neuropsychiatric disorders characterized by the presence of stereotypic motor symptoms. Planning and execution of motor actions are controlled by the dorsal striatum, a brain region that promotes or suppresses motor movement by activating striatal neurons from the direct- or indirect-pathway, respectively. Despite the dorsal striatum being affected in motor disorders and by CS exposure, how CS affects the two opposing pathways is not fully understood. Here, we report that CS in mice selectively potentiates the direct-pathway, while sparing the indirect-pathway. Specifically, we show that CS both increases excitation and reduces inhibition over direct-pathway neurons in the dorsomedial striatum (DMS). Furthermore, inhibitory interneurons located in the DMS also display reduced excitatory drive after chronic stress, thus amplifying striatal disinhibition. Altogether, we propose a model where both increased excitatory drive and decreased inhibitory drive in the striatum causes disinhibition of basal ganglia's motor direct pathway - a mechanism that might explain the emergence of motor stereotypies and tic disorders under stress.

Sucrose preference test: A systematic review of protocols for the assessment of anhedonia in rodents.

Anhedonia is described as a decreased ability to experience rewarding and enjoyable activities, a core symptom of major depressive disorder. The sucrose preference test (SPT) is a widely used and reliable behavioural test to assess anhedonia in rodents, based on a two-bottle choice paradigm. To date, different protocols are in use, inducing variability between researchers and hampering comparisons between studies. We performed a systematic review of the SPT protocols used in 2021 to identify the parameters in which they differ and their potential impact. We searched a total of four databases (PubMed, Scopus, Web of Science and Science Direct), from 1st January 2021 to 31st December 2021, and screened a total of 1066 articles. After screening by title and abstract, a total of 415 articles were included in this review. We extracted and analysed the different procedures used, the type of sweet solution and the habituation, deprivation, and testing protocols. The overall quality of the studies was considered very good, however, SPT protocols were extremely variable between studies with a total of 65 different habituation protocols and 104 combinations of food/water deprivation and preference testing duration. As the SPT is one of the most used tests to assess anhedonia in rodents, this work raises awareness of the great variability in SPT protocols being currently used. Furthermore, we call for standardization in the protocol used, and overall improvement of data reporting of methodologies and results, to increase the consistency between studies and allow a better comparison of results between different labs.

Injection of kaolin/carrageenan in the rat knee joint induces progressive experimental knee osteoarthritis.

ABSTRACT: Osteoarthritis (OA), the most common joint disorder worldwide, is characterized by progressive degeneration of articular and periarticular structures, leading to physical and emotional impairments that greatly affect the quality of life of patients. Unfortunately, no therapy has been able to halt the progression of the disease. Owing to the complexity of OA, most animal models are only able to mimic a specific stage or feature of the human disorder. In this work, we demonstrate the intraarticular injection of kaolin or carrageenan leads to the progressive degeneration of the rat's knee joint, accompanied by mechanical hyperalgesia and allodynia, gait impairments (reduced contact area of the affected limb), and radiological and histopathological findings concomitant with the development of human grade 4 OA. In addition, animals also display emotional impairments 4 weeks after induction, namely, anxious and depressive-like behaviour, important and common comorbidities of human OA patients. Overall, prolonging kaolin or carrageenan-induced monoarthritis mimics several important physical and psychological features of human OA in both male and female rodents and could be further applied in long-term studies of OA-associated chronic pain.

Comparative neurotoxicity of dietary methylmercury and waterborne inorganic mercury in fish: Evidence of optic tectum vulnerability through morphometric and histopathological assessments.

This work investigated the effects of inorganic mercury (iHg) and methylmercury (MeHg) on the fish optic tectum morphology, viz. in relation to: (i) vulnerability of specific optic tectum layers; (ii) preferential targeting of Hg forms to neurons or glial cells; (iii) comparative toxicity of iHg and MeHg in this brain area that is in the maintenance of several fish behaviors. Two experiments exposing juvenile white seabream (Diplodus sargus) to waterborne iHg [HgCl2 (2 µg L-1)] and dietary MeHg (8.7 µg g-1) were performed, comprising both exposure (7 and 14 days; E7 and E14, respectively) and post-exposure (28 days; PE28) periods. Morphometric assessments were performed using stereological methods where the layers of the optic tectum were outlined, while its area and the number of neurons and glial cells were estimated. A histopathological assessment was also performed per section and per layer of optic tectum. iHg exposure did not trigger the loss of neurons during the exposure periods, while a decrease of glial cells was detected in a single layer of the optic tectum at E14. Differently, upon MeHg exposure, a decrease on the number of neurons and glial cells was found in several layers of optic tectum. In the post-exposure, both Hg forms triggered the loss of neurons, while only MeHg exposure led to a decrease on the number of glia cells. The histopathological assessment pointed out a higher toxicity of MeHg in the optic tectum layers, particularly in the post-exposure period, while no significant alterations were found in fish exposed to iHg. Hg forms targeted preferentially neurons. iHg and MeHg are relevant neurotoxicants to fish, with MeHg exposure leading to a higher toxicity than iHg in the optic tectum. After 28 days of post-exposure, iHg and MeHg neurotoxicity remained prominent, suggesting long-term effects of these toxicants.

Retrospective Survey and Analysis of Anaesthesia and Outcomes in Paediatric Cleft Lip or Palate Surgery in a Tertiary Care Center, Portugal.

INTRODUCTION: Orofacial clefts are the most common craniofacial abnormalities, affecting approximately one in 700 newborns each year. The anaesthetic management of these patients is challenging, including difficulties in airway approach and respiratory complications that have direct implications in the final outcome. AIM: The present study aimed to characterize the anesthetic approach to paediatric patients undergoing cleft palate or lip surgical repair and review the perioperative anesthetic complications in a tertiary Portuguese hospital. METHODS: Data were collected from a retrospective review of the patient records which included anaesthesia perioperative notes of paediatric patients submitted to cleft surgery repair during a five-year period (2016 to 2021). Demographic, pre-anaesthetic characteristics, anaesthetic management and perioperative complications were recorded. RESULTS: A total of 102 patients were included, with a median age of 1.5 years. Congenital syndromes were present in 14 (13.7%) of the children included. Inhalational induction of anaesthesia with sevoflurane was the preferred approach in 86 cases (84.3%), with neuromuscular blockade being used in 59 cases (57.8%). Intubation was achieved at first attempt in 91 (89.2%) cases with four (3.9%) patients needing three or more attempts. Intraoperative respiratory-related complications were the most frequent, occurring in 22 (21.6%) cases. These include multiple attempts to intubation, desaturation due to bronchospasm or laryngospasm. The average length of stay was two days. Postoperative complications were recorded in 17 (16.7%) of patients. DISCUSSION: The predominance of airway and respiratory complications occurring in cleft is consistent with previous studies. Care must be taken in order to avoid such complications in the perioperative period by following protocols, having skilled personnel, appropriate monitoring equipment and airway devices available during cleft surgeries to minimise morbidity.

Debriefing or Feedback: Exploring the Impact of Two Post-Scenario Discussion Methods in the Acquisition and Retention of Non-Technical Skills.

INTRODUCTION: There is a paucity of quantitative studies objectively comparing debriefing and feedback as methods for post-scenario discussion and its impact on healthcare teams' acquisition and retention of non-technical skills. The main purpose of this study is to provide some insight on this research question, using a sample of medical students. A secondary objective explores students' opinion and preference on the post-scenario discussion. MATERIAL AND METHODS: Forty-five medical students were distributed among 15 teams, and randomly allocated to two groups. Each team participated in three different simulated scenarios, with similar levels of difficulty and opportunities to apply specific non-technical skills: leadership, communication, and task management. To assess the acquisition and retention of skills, scenarios occurred on days one (baseline), two (acquisition) and 20 (retention). Team performance was objectively evaluated by an observer, using scenario recordings. Students individually assessed different aspects of debriefing and feedback. RESULTS: Both debriefing and feedback groups showed similar overall increase in objective scores, with significant increase between days one and two (acquisition), and a smaller increase between days two and 20 (retention). Students indicated debriefing as the preferred discussion method. CONCLUSION: Debriefing and feedback are effective post-scenario discussion methods, promoting acquisition and retention of non-technical skills, by undergraduate students. Allying debriefing reflexive practice with feedback directive style, and shifting appropriately between facilitation and instruction, can be a good compromise to achieve a timely and educationally meaningful discussion.

Introdução: Há uma escassez de estudos quantitativos comparando objetivamente o debriefing e o feedback como métodos de discussão pós-cenário e o seu impacto na aquisição e retenção de competências não-técnicas pelas equipas de saúde. O objetivo principal deste estudo é explorar esta questão de investigação, usando uma amostra de estudantes de medicina. Adicionalmente, foi analisada a opinião e preferência dos estudantes sobre o método de discussão pós-cenário. Material e Métodos: Quarenta e cinco estudantes de medicina foram distribuídos em 15 equipas e alocados aleatoriamente a dois grupos. Cada equipa participou em três cenários de simulação diferentes, com níveis de dificuldade semelhantes e as mesmas oportunidades para aplicar as seguintes competências não-técnicas específicas: liderança, comunicação e gestão de tarefas. Para avaliar a aquisição e retenção de competências, os cenários decorreram nos dias um (linha de base), dois (aquisição) e 20 (retenção). O desempenho de cada equipa foi avaliado objetivamente por um observador, através da análise das gravações dos cenários e de uma checklist. Os estudantes foram ainda convidados a avaliar individualmente a condução do debriefing e do feedback. Resultados: Ambos os grupos (debriefing e feedback) demonstraram um incremento semelhante nas pontuações objetivas, com um aumento acentuado entre os dias um e dois (aquisição) e um aumento ligeiro entre os dias dois e 20 (retenção). Os estudantes indicaram o debriefing como método de discussão preferencial. Conclusão: O debriefing e o feedback são métodos eficazes de discussão pós-cenário, promovendo a aquisição e retenção de competências não-técnicas por estudantes pré-graduados. A aliança da prática reflexiva do debriefing com o estilo diretivo de feedback, alternando apropriadamente entre facilitação e instrução, é um compromisso aceitável para alcançar uma discussão educacionalmente significativa num tempo limitado.
