Attitudes and experiences related to the deaths of COVID-19 patients among nursing staff: A qualitative evidence synthesis.

AIM: To identify and synthesize the experiences and attitudes of nursing staff regarding the deaths of COVID-19 patients. REVIEW METHODS: A qualitative evidence synthesis was carried out, using Noblit and Hare's meta-ethnographic approach. The review protocol was listed in PROSPERO (CRD42022330928). Studies published from January 2020 to January 2022 that met the criteria were searched in PubMed, Web of Science, Scopus, CINAHL, CUIDEN and PsycInfo. A total of 12 articles were included. RESULTS: Thirty-three metaphors emerged, which were grouped into three main themes: Determining factors of care, Feelings about death and Strategies for coping with death. Nurses reported the high emotional toll, the absence of family and the lack of staff, protocol and training as determining factors. Furthermore, staff had doubts about the quality of care that COVID-19 patients received. As coping strategies, nurses developed avoidance behaviours towards COVID-19 patients, selective memories, resilience, and/or leaving the profession. CONCLUSIONS: The difficulty in providing adequate nursing care and the high number of deaths has increased anxiety and stress among nurses. These factors, alongside their lived experiences of seeing patients suffering, many dying alone without family members, have had psychological repercussions on nursing staff. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: The results demonstrate a high emotional toll and doubts surrounding their caregiving role caused by the lack of professional training needed to face a pandemic. This research shows what has been learned for future pandemics and highlights basic components that could provide a foundation for coping interventions for healthcare professionals. IMPACT: WHAT PROBLEM DID THE STUDY ADDRESS?: The challenges posed by COVID-19 patient deaths for nursing staff around the world and also by the pandemic circumstances in which those deaths occurred. WHAT WERE THE MAIN FINDINGS?: The high number of deceased patients who were isolated from family members, communication with family members and doubts surrounding care given during the pandemic have created feelings of fear, stress and anxiety, as well as obsessive thoughts that have changed nursing staff's perception of death due to COVID-19. WHERE AND ON WHOM WILL THE RESEARCH HAVE AN IMPACT?: Results will be useful for preparing for future pandemics, and for policymakers and health staff in supporting healthcare professionals by creating programmes to help them cope with the emotional toll they have felt after dealing with death in such unprecedented circumstances. REPORTING METHOD: The authors have adhered to the PRISMA guidelines and the eMERGe Reporting Guidance. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Spanish adaptation of the Stillbirth Stigma Scale (SSS).

The death of a baby in the perinatal period is considered a disenfranchized grief that can be a source of significant symptoms of guilt, shame, and stigma. There is a lack of validated instruments for assessing the stigma associated with perinatal grief. The aim of this study was to examine the psychometric properties (factor structure, reliability, and validity) of the Spanish version of the Stillbirth Stigma Scale (SSS) in parents who have experienced a perinatal loss. A total of 291 participants (mostly mothers) completed an online questionnaire that included the SSS and other measures. The best-fitting factor structure was a second-order model with four dimensions and adequate reliability values. In terms of validity, we found statistically significant relationships between the SSS scores and the variables of self-esteem, complicated grief, event centrality, depression, and anxiety. In conclusion, the Spanish adaptation of the SSS is deemed to have adequate psychometric properties.

Spanish adaptation of the perinatal grief intensity scale.

AIMS/BACKGROUND: Assessing the intensity of perinatal grief is very important for identifying the more complex cases in mothers and fathers. Despite this, there are few assessment tools available. The aim of this study was to analyse the psychometric properties (factorial structure, reliability, and validity) of the Spanish version of the Perinatal Grief Intensity Scale (PGIS). DESIGN/METHODS: An online survey was completed by 291 mothers and fathers who had suffered perinatal loss in the previous six years. RESULTS: The results showed adequate fit indexes for the three-factor model of the PGIS: reality, confront others, and congruence. Reliability values for the overall scale and subscales were adequate. Finally, with regard to validity, significant (p < .05) and positive relationships were found with levels of complicated grief, event centrality, guilt, anxiety, and depression. There were also differences depending on whether participants exhibited high or low levels of complicated grief, and on the number of weeks of pregnancy at the time of the loss. CONCLUSION: In conclusion, the Spanish adaptation of the PGIS has adequate reliability and validity scores and a factorial structure consistent with the original version.

The prognostic value of the NECPAL instrument, Palliative Prognostic Index, and PROFUND index in elderly residents of nursing homes with advanced chronic condition.

BACKGROUND: It is essential to assess the need for palliative care and the life prognosis of elderly nursing home residents with an advanced chronic condition, and the NECPAL ICO-CCOMS©4.0 prognostic instrument may be adequate for both purposes. The objective of this study was to examine the predictive capacity of NECPAL, the Palliative Prognosis Index, and the PROFUND index in elderly residents with advanced chronic condition with and without dementia, comparing their results at different time points. METHODS: This prospective observational study was undertaken in eight nursing homes, following the survival of 146 residents with advanced chronic condition (46.6% with dementia) at 3, 6, 12, and 24 months. The capacity of the three instruments to predict mortality was evaluated by calculating the area under the receiver operating characteristic curve (AUC), with 95% confidence interval, for the global population and separately for residents with and without dementia. RESULTS: The mean age of residents was 84.63 years (± 8.989 yrs); 67.8% were female. The highest predictive capacity was found for PROFUND at 3 months (95%CI: 0.526-0.756; p = 0.016), for PROFUND and NECPAL at 12 months (non-significant; AUC > 0.5), and NECPAL at 24 months (close-to-significant (AUC = 0.624; 95% CI: 0.499-0.750; p = 0.053). The highest capacity at 12 months was obtained using PROFUND in residents with dementia (AUC = 0.698; 95%CI: 0.566-0.829; p = 0.003) and NECPAL in residents without dementia (non-significant; AUC = 0.649; 95%CI: 0.432-0.867; p = 0.178). Significant differences in AUC values were observed between PROFUND at 12 (p = 0.017) and 24 (p = 0.028) months. CONCLUSIONS: PROFUND offers the most accurate prediction of survival in elderly care home residents with advanced chronic condition overall and in those with dementia, especially over the short term, whereas NECPAL ICO-CCOMS©4.0 appears to be the most useful to predict the long-term survival of residents without dementia. These results support early evaluation of the need for palliative care in elderly care home residents with advanced chronic condition.

Patients' experiences and perceptions of dignity in end-of-life care in emergency departments: A qualitative study.

AIMS: To explore and understand the experiences of patients with advanced illness in relation to dignity during end-of-life care in emergency departments. DESIGN: Qualitative study based on Gadamer's hermeneutics. METHODS: Between September 2019 and February 2020, 16 in-depth interviews were carried out with advanced illness patients who attended emergency departments. The participants were informed priorly and signed informed consent. The data were analysed using an inductive strategy for finding emerging themes. The Consolidated Criteria for Reporting Qualitative Research was used for writing the study's report. RESULTS: In the data analysis process, two main themes emerged that glean the experiences of patients in relation to dignity during end-of-life care in emergency departments. 'Dignity as an individual's attribute' and 'Acting with dignity: Dignity as a behavioural attribute'. CONCLUSION: Patient dignity in end-of-life care is centred around the principle of control (of oneself, one's death and one's emotions). The strategies required for patients to preserve their dignity can be somewhat incompatible with the dynamics and objectives of healthcare professionals who work in emergency departments. IMPACT STATEMENT: The dignity of patients with advanced illness who attend emergency departments is a relevant issue that merits being addressed from the patients' perspective. Participants have identified that dignity is a way of being and behaving in the face of illness. Emergency departments need to respect end-of-life patients' desires by supporting and accompanying them, avoiding therapeutic obstinacy. We recommend care to be centred on patients' well-being, to respect their autonomy and decision-making processes, and to allow prompt referrals to palliative care services. PATIENT OR PUBLIC CONTRIBUTION: Managers from the Emergency Departments participated in the study design and patients' recruitment. Patients' relatives were informed about the study's aim, and they contributed to the development of the interview protocol.

Cultural adaptation and validation of the Quality of Dying in Long-term Care (QoD-LTC and QoD-LTC-C) scales by caregivers in nursing homes.

BACKGROUND: There is a lack of tools that can evaluate quality of dying in nursing homes from the perspective of deceased patients' caregivers. The aim of this study was to adapt and validate the caregivers' versions of the Quality of Dying in Long-Term Care (QoD-LTC) and Quality of Dying in Long-Term Care Complete (QoD-LTC-C) scales in the Spanish context. METHODS: This was a cultural adaptation and validation study. The scales were translated from English to Spanish and vice versa, and 13 experts in end-of-life care participated in a two-round Delphi panel. Caregivers of 69 deceased residents from seven nursing homes in southern Spain completed both scales. Reliability, feasibility, and concurrent validity with global quality of dying perception and symptom burden (Edmonton Symptom Assessment Scale), were evaluated. RESULTS: Spanish caregivers' version of the QoD-LTC scale showed good internal consistency for the total scale (α = 0.74) and each of its three factors, and good inter-rater reliability (ICC = 0.50) and test-retest reliability (ICC = 0.81). The Spanish QoD-LTC-C scale for caregivers showed good internal consistency for the total scale (α = 0.81) and for its component factors, and good test-retest reliability (ICC = 0.89) and inter-rater reliability (ICC = 0.66). Both scales correlated with family caregivers' global perception of deceased residents' quality of dying (r = 0.39; r = 0.32), but not with the ESAS score. CONCLUSIONS: Both scales presented an adequate factorial structure, internal consistency, and reliability to assess caregivers' perception of the quality of dying in Spanish nursing homes.

NUrsing Homes End of Life care Program (NUHELP): developing a complex intervention.

BACKGROUND: Nursing homes are likely to become increasingly important as end-of-life care facilities. Previous studies indicate that individuals residing in these facilities have a high prevalence of end-of-life symptoms and a significant need for palliative care. The aim of this study was to develop an end-of-life care program for nursing homes in Spain based on previous models yet adapted to the specific context and the needs of staff in nursing homes in the country. METHODS: A descriptive study of a complex intervention procedure was developed. The study consisted of three phases. The first phase was a prospective study assessing self-efficacy in palliative care (using the SEPC scale) and attitudes towards end-of-life care (using the FATCOD-B scale) among nursing home staff before and after the completion of a basic palliative care training program. In the second phase, objectives were selected using the Delphi consensus technique, where nursing home and primary care professionals assessed the relevance, feasibility, and level of attainment of 42 quality standards. In phase 3, interventions were selected for these objectives through two focus group sessions involving nursing home, primary care, and palliative care professionals. RESULTS: As a result of the training, an improvement in self-efficacy and attitudes towards end-of-life care was observed. In phase 2, 14 standards were selected and grouped into 5 objectives: to conduct a comprehensive assessment and develop a personalized care plan adapted to the palliative needs detected; to provide information in a clear and accessible way; to request and record advance care directives; to provide early care with respect to loss and grief; to refer patients to a specialized palliative care unit if appropriate, depending on the complexity of the palliative care required. Based on these objectives, the participants in the focus group sessions designed the 22 interventions that make up the program. CONCLUSIONS: The objectives and interventions of the NUHELP program constitute an end-of-life care program which can be implemented in nursing homes to improve the quality of end-of-life care in these facilities by modifying their clinical practice, organization, and relationship with the health system as well as serving as an example of an effective health intervention program.

Evaluation of atopy schools for parents.

INTRODUCTION: Atopic dermatitis is a highly prevalent chronic disorder. Therapeutic education in diseases of this kind is essential in order to improve patient management and prognosis. A study was conducted regarding parent satisfaction following educational sessions in an Atopy School organized by a multidisciplinary team. MATERIAL AND METHODS: E-mail surveys with variables scored by means of a Likert scale were administered among the parents participating in the workshops organized by the Atopy School. The educational program comprised four sessions with a duration of 4 hours. RESULTS: Ninety-five percent of the parents were satisfied after participating in the workshops, and were of the opinion that the therapeutic education received was useful for improving control of the illness of their children. Likewise, 85% were satisfied or very satisfied with the help received in the sessions for control of the disease during flare-ups, and 90% considered the data and advice received in the sessions to be of use in improving quality of life of both the children and the family as a whole. CONCLUSIONS: The Atopy School afforded caregiver empowerment, and the parents were satisfied and felt more secure in dealing with the disease of their children-thereby improving the prognosis and quality of life.

Partial inclusion of bis(1,10-phenanthroline)silver(I) salicylate in ß-cyclodextrin: Spectroscopic characterization, in vitro and in silico antimicrobial evaluation.

Silver complexes containing 1,10-phenanthroline as a coordinated ligand have been of great interest due to their antibacterial and antifungal pharmacological properties. In this paper, we describe the synthesis of a new partial inclusion complex of bis(1,10-phenanthroline)silver(I) salicylate in ß-cyclodextrin (ß-CD) which was synthesized with a good yield. The compounds were characterized by FTIR, 1H, 13C NMR including 1H-1H COSY, TGA/DSC, elemental analysis (CHN), and X-ray powder diffraction. The results suggest the presence of non-covalent interactions such as hydrogen bonds, van der Waals forces, and hydrophobic interactions in the formation of the partial inclusion compound between ß-CD and bis(1,10-phenanthroline)silver(I) salicylate [Ag(phen)2]salH. Additionally, an in silico prediction of 1,10-phenanthroline biological activities was carried out and the acquired data suggests several potential targets associated with the antimicrobial activity of this compound and its silver complex. Most predicted targets are related to antimicrobial virulence and resistance that are a serious threat to global public health. The inclusion compound showed a higher inhibiting growth of Candida albicans than the free complex [Ag(phen)2]salH indicating that the formation of the inclusion complex with ß-CD increases the bioavailability of the antimicrobial active species [Ag(phen)2]+ of the new silver(I) compound.

Prognostic Models Associated with 6-Month Survival of Patients Admitted to Nursing Homes.

BACKGROUND: Health status and the needs presented by people admitted to nursing homes make it necessary to contemplate aspects such as prognosis to offer quality palliative care. OBJECTIVE: To compare the prognostic utility in nursing homes of two prognostic models of 6-month survival based on the Palliative Prognostic Index (PPI) or Palliative Performance Status (PPS) instruments and palliative needs indicators. METHODS: A longitudinal prospective observational and analytical cohort study of survival and prognostic models in 88 patients with palliative needs (assessed by the NECPAL-ICO-CCOMS©) from an Andalusian (Spain) nursing home was performed. Sociodemographic and clinical variables were assessed, and 6 months later, in September 2017, survival was checked. Multiple logistic regression analysis was performed using the R-Commander program (version 3.2.2). RESULTS: Two models of the logistic regression analysis met the fit criteria. The two models combined the Surprise Question, the presence of persistent symptoms, and the clinical indicators of severity from the NECPAL tool, in addition to the Charlson Comorbidity Index, and varied only in terms of the latter variable, including the PPI in the first model and the PPS in the second. In the first model, significant associations were identified between 6-month survival and the persistent symptoms variable (OR = 7.78, p = 0.025, 95% CI = 1.45-60.92) and PPI (OR = 1.94, p < 0.001, 95% CI = 1.21). In the second model, 6-month survival was also significantly associated with the persistent symptoms variable (OR = 4.57, p = 0.045, 95% CI = 1.07-22.41) and the PPS (OR = 0.93, p = 0.001, 95% CI = 0.88-0.96). CONCLUSIONS: Prognostic models such as ours that include variables commonly included in clinical assessments can help nursing home professionals prioritize and ensure adequate mobilization of palliative care resources, which are very limited in these institutions.

Molecular sensitization patterns and influence of molecular diagnosis in immunotherapy prescription in children sensitized to both grass and olive pollen.

BACKGROUND: The overlapping grass and olive pollen seasons in Spain and the phenomenon of cross-reactivity can make it difficult to determine the true causative agent of seasonal allergic rhinitis when only skin prick tests with whole extracts are used. The aim of the GRAMOLE study was to determine sensitization patterns to the major grass and olive pollen allergens detected using specific recombinant IgE and to explore how this knowledge affected physicians' choice of allergen-specific immunotherapy. METHODS: Epidemiological, observational, multicenter, cross-sectional study. Results from children under 18 years of age diagnosed with seasonal allergic rhinitis by positive skin prick tests to olive and grass pollen were analyzed. Specific IgE to Phl p 1+5, Ole e 1, and Phl p 7+12 was determined. Investigators specified the optimal composition of allergen immunotherapy before and after knowing the results of the molecular diagnosis. RESULTS: A total of 281 patients with a mean age of 13.4 years were included. Double sensitization to both major allergens was found in vitro in 76% of children for an IgE cutoff point of 0.35 kU/L. When the molecular diagnosis results were known, specialists changed the composition of the prescribed immunotherapy in 52.87% of cases. CONCLUSIONS: Double sensitization to grass and olive pollen is common in Spain and also occurs in the pediatric population. Molecular diagnosis using specific IgE may help improve immunotherapy selection in polysensitized patients.

RESULTS OF MECHANIC VERSUS MOTORIZED STAPLER USED IN GASTRIC SURGERY: PROSPECTIVE STUDY.

BACKGROUND: Mechanic sutures represent an enormous benefit for digestive surgery in decreasing postoperative complications. Currently, the advantages of motorized stapler are under evaluation. AIMS: To compare the efficacy of mechanic versus motorized stapler in gastric surgery, analyzing rate of leaks, bleeding, time of stapling, and postoperative complications. METHODS: Ninety-eight patients were submitted to gastric surgery, divided into three groups: laparoscopic sleeve gastrectomy (LSG) (n=47), Roux-en-Y gastric bypass (LRYGB) (n=30), and laparoscopic distal gastrectomy (LDG) (n=21). Motorized staplers were employed in 61 patients. The number of firings, number of clips, time of total firings, total time to complete the surgery, and postoperative outcome were recorded in a specific protocol. RESULTS: Patients submitted to LSG, LRYGB, and LDG recorded a shorter time to complete the procedure and a smaller number of firings were observed using motorized stapler (p<0.0001). No differences were identified regarding the number of clips used in patients submitted to LSG. In the group that used mechanic stapler to complete gastrojejunostomy, jejuno-jejuno-anastomosis, and jejunal transection, it was observed more prolonged time of firing and total time for finishing the procedure (p=0.0001). No intraoperative complications were found comparing the two devices used. Very similar findings were noted in the group of patients undergoing LDG. CONCLUSIONS: The motorized stapler offers safety and efficacy as demonstrated in prior reports and is relevant since less total time of surgical procedure without intraoperative or postoperative complications were confirmed.

Clinical Characteristics and Outcomes of an Intensive Maternal Care Unit in a Tertiary Hospital in the Philippines.

Objectives: This is the first study that provides an overview of the characteristics of a specialized Intensive Maternal Care Unit (IMU) that caters to obstetric-related conditions in the Philippines. This study aims to describe the different kinds of cases admitted into this facility, the different medical and surgical interventions employed, length of hospital stay, and maternal and fetal outcomes of these patients. Methods: This is a cross-sectional descriptive study based on a chart review of medical records and admission charts of patients admitted to the Intensive Maternal Unit of a tertiary hospital in Manila from January 2017 to December 2019. Results: There were a total of 17,185 obstetric admissions from 2017-2019. There were a total of 841 admissions (4%) into the Intensive Maternal Unit, with an average of 280 admissions per year. The average length of Intensive Maternal Unit stay was 10.46 days and the average length of hospital stay was 12.98 days. Maternal outcomes were the following: 56.89% were discharged undelivered while 38.92% delivered on their initial admission. The maternal mortality rate was 2.39% among those admitted to the IMU. Among those discharged undelivered, 43% were re-admitted, 6% were admitted twice, and 4% were admitted three times. The most common reason for admission was pregnancy-related hypertensive diseases (34%). Blood transfusion (2.4%), the use of ventilator support (0.6%), and the use of inotropic drugs (0.6%) were the major medical interventions. Cesarean section was the most common surgical intervention, seen in 54.49% of patients. Most neonates were admitted to the neonatal ICU (23.95%), at an average pediatric age of 33 weeks, with an average length of stay in the Neonatal ICU of 12.33 days. Conclusion: Pregnant women are a special group of patients with different needs compared to the general patient population. Pregnancy-associated hypertensive disease is the most common cause of admission to the IMU and hospitals should be able to cater to these patients who will present in their institutions, as this may lead to poor maternal and neonatal outcomes. An Intensive Care Unit dedicated to complicated obstetric care in institutions is recommended to cater to high-risk pregnancies.

Clinical Simulation in Palliative Care for Undergraduate Nursing Students: A Randomized Clinical Trial and Complementary Qualitative Study.

BACKGROUND: a lack of adequate training in palliative care leads to a greater emotional burden on nurses. PURPOSE: to assess the effect of a simulation using standardized patients on self-efficacy in palliative care, ability to cope with death, and emotional intelligence among nursing students. METHODS: a randomized clinical trial and qualitative study. A total of 264 nursing students in a palliative care module completed the Bugen, trait meta-mood, and self-efficacy in palliative care scales after active participation in the simulation (n = 51), watching the simulation (n = 113), and the control group (n = 100). An ANOVA with a multi-comparative analysis and McNemar's tests for paired samples were calculated. Active participants were interviewed, and a thematic analysis was conducted. RESULTS: there was an improvement after the assessment in all three groups assessed for coping with death (p < 0.01), emotional intelligence (p < 0.01), and self-efficacy (p < 0.01). In addition, the active group improved more than the observer group and the control group in coping with death, attention, and repair. The students in the interviews identified sadness and an emotional lack of control. CONCLUSIONS: the simulation improved nursing students' self-efficacy in palliative care. This effect was partially stronger in the active group.

Identifying and Exploring Jean Watson's Theory of Human Caring in Nursing Approaches for Patients with Psychoactive Substance Dependence in Medical and Surgical Acute Wards.

Patients with substance use disorders may view healthcare professionals as capable of supporting them through their suffering and experience. Although numerous studies have focused on the roles, approaches, and attitudes of healthcare professionals, there is a lack of information on the nursing perspective. This study aims to explore the experiences and nursing approaches towards patients with psychoactive substance dependence admitted to an Italian acute hospital ward. A qualitative phenomenological study was conducted. Data were collected using semi-structured face-to-face interviews. The interviews were transcribed, read thoroughly, and analysed. Fifteen nurses were interviewed. Six main themes were extracted: (1) origin context, (2) participants' personal thoughts, (3) type of approach provided, (4) school education received on the topic, (5) effectiveness of rehabilitative therapy, and (6) methods that can improve nursing care. The findings suggest that most respondents experience stigma and discrimination when providing care to these patients. In response to the results obtained, models have been suggested, such as Jean Watson's Human Caring Theory, which shows how practising a holistic approach based on empathy and active listening can improve the relationship between nurses and patients. Furthermore, to eliminate stereotypes, it would be appropriate to act on the university education of nurses. This study was not registered.

A systems approach to modeling Community-Based Environmental Monitoring: a case of participatory water quality monitoring in rural Mexico.

Community-Based Environmental Monitoring (CBM) is a social practice that makes a valuable contribution to environmental management and construction of active societies for sustainable future. However, its documentation and analysis show deficiencies that hinder contrast and comparison of processes and effects. Based on systems approach, this article presents a model of CBM to orient assessment of programs, with heuristic or practical goals. In a focal level, the model comprises three components, the social subject, the object of monitoring, and the means of action, and five processes, data management, social learning, assimilation/decision making, direct action, and linking. Emergent properties were also identified in the focal and suprafocal levels considering community self-organization, response capacity, and autonomy for environmental management. The model was applied to the assessment of a CBM program of water quality implemented in rural areas in Mexico. Attributes and variables (indicators) for components, processes, and emergent properties were selected to measure changes that emerged since the program implementation. The assessment of the first 3 years (2010-2012) detected changes that indicated movement towards the expected results, but it revealed also the need to adjust the intervention strategy and procedures. Components and processes of the model reflected relevant aspects of the CBM in real world. The component called means of action as a key element to transit "from the data to the action." The CBM model offered a conceptual framework with advantages to understand CBM as a socioecological event and to strengthen its implementation under different conditions and contexts.

A comparison between neurological clinical signs, cerebrospinal fluid analysis, cross-sectional CNS imaging, and infectious disease testing in 168 dogs with infectious or immune-mediated meningoencephalomyelitis from Brazil.

This retrospective study evaluated canine patients with presumptively diagnosed meningoencephalomyelitis (ME) based on neurological clinical signs, cerebrospinal fluid (CSF) analysis, cross-sectional imaging, and infectious disease testing with a limited neurological-focused polymerase chain reaction (PCR) panel performed on blood and CSF. The first goal was to determine the proportion of dogs where the condition was caused by an infectious agent versus a probable immune-mediated etiology (i.e., meningoencephalomyelitis of unknown origin; MUO) in our geographic region. The secondary goals of this study were to examine and define associations between abnormal CSF test results and cross-sectional neuroimaging findings, in addition to defining the age and most common neurological clinical signs in each group of ME. A total of 168 dogs matched the inclusion criteria with magnetic resonance imaging (MRI) performed in 130 dogs and computed tomography (CT) performed in 38 dogs. Presumptive MUO was observed in 152/168 (90.5%) of dogs and infectious ME was identified in 16/168 (9.5%) of dogs (p < 0.0001). Canine distemper virus (CDV) was the most common cause of infectious ME in 10/16 dogs (62.5%). Of the total cases with a positive infectious disease result, 3/16 (18.7%) had normal CSF results and 13/16 (81.3%) had abnormal CSF results (p = 0.0078). MRI and CT abnormalities in the brain were detected in 74 and 39% of dogs with inflammatory CSF, respectively. MRI and CT abnormalities in the spinal cord were detected in 90 and 57% of dogs with inflammatory CSF results, respectively. Age was not significantly different between infectious ME and presumptive MUO groups (p = 0.15). Seizures were the most common clinical sign reported for both MUO (36.8% of cases) and infectious ME (31.2% of cases). In conclusion, presumptive MUO is significantly more common than infectious ME in this population of dogs. Furthermore, although normal CSF results were uncommon in dogs with infectious ME, this finding occurred in several patients (3/16), suggesting that infectious disease testing should be considered even in the face of normal CSF results. Finally, MRI was more sensitive than CT in the detection of abnormalities when dogs with ME had inflammatory CSF results but was not 100% sensitive, suggesting CSF analysis should be performed to rule out inflammation even when no abnormalities are detected on MRI or CT.

Understanding for Prevention: Qualitative and Quantitative Analyses of Suicide Notes and Forensic Reports.

Suicide risk is associated with vulnerabilities and specific life events. The study's objective was to explore the relevance of data from forensic documentation on suicide deaths to the design of person-centered preventive strategies. Descriptive and thematic analyses were conducted of forensic observations of 286 deaths by suicide, including some with suicide notes. Key findings included the influence of health-and family-related adverse events, emotional states of loss and sadness, and failures of the health system to detect and act on signs of vulnerability, as confirmed by the suicide notes. Forensic documentation provides useful information to improve the targeting of preventive campaigns.

Chitosan as an Outstanding Polysaccharide Improving Health-Commodities of Humans and Environmental Protection.

Public health, production and preservation of food, development of environmentally friendly (cosmeto-)textiles and plastics, synthesis processes using green technology, and improvement of water quality, among other domains, can be controlled with the help of chitosan. It has been demonstrated that this biopolymer exhibits advantageous properties, such as biocompatibility, biodegradability, antimicrobial effect, mucoadhesive properties, film-forming capacity, elicitor of plant defenses, coagulant-flocculant ability, synergistic effect and adjuvant along with other substances and materials. In part, its versatility is attributed to the presence of ionizable and reactive primary amino groups that provide strong chemical interactions with small inorganic and organic substances, macromolecules, ions, and cell membranes/walls. Hence, chitosan has been used either to create new materials or to modify the properties of conventional materials applied on an industrial scale. Considering the relevance of strategic topics around the world, this review integrates recent studies and key background information constructed by different researchers designing chitosan-based materials with potential applications in the aforementioned concerns.

Self-assembled organic-inorganic magnetic hybrid adsorbent ferrite based on cyclodextrin nanoparticles.

Organic-inorganic magnetic hybrid materials (MHMs) combine a nonmagnetic and a magnetic component by means of electrostatic interactions or covalent bonds, and notable features can be achieved. Herein, we describe an application of a self-assembled material based on ferrite associated with ß-cyclodextrin (Fe-Ni/Zn/ßCD) at the nanoscale level. This MHM and pure ferrite (Fe-Ni/Zn) were used as an adsorbent system for Cr(3+) and Cr(2)O(7) (2-) ions in aqueous solutions. Prior to the adsorption studies, both ferrites were characterized in order to determine the particle size distribution, morphology and available binding sites on the surface of the materials. Microscopy analysis demonstrated that both ferrites present two different size domains, at the micro- and nanoscale level, with the latter being able to self-assemble into larger particles. Fe-Ni/Zn/ßCD presented smaller particles and a more homogeneous particle size distribution. Higher porosity for this MHM compared to Fe-Ni/Zn was observed by Brunauer-Emmett-Teller isotherms and positron-annihilation-lifetime spectroscopy. Based on the pKa values, potentiometric titrations demonstrated the presence of ßCD in the inorganic matrix, indicating that the lamellar structures verified by transmission electronic microscopy can be associated with ßCD assembled structures. Colloidal stability was inferred as a function of time at different pH values, indicating the sedimentation rate as a function of pH. Zeta potential measurements identified an amphoteric behavior for the Fe-Ni/Zn/ßCD, suggesting its better capability to remove ions (cations and anions) from aqueous solutions compared to that of Fe-Ni/Zn.
