Impact of multicomponent intervention on hospitalized clinical patient outcomes: A pre-post study in a university hospital.

BACKGROUND AND OBJECTIVE: Hospitalization significantly interferes with the individual's well-being and it occurs both during and after the hospitalization period. Different approaches to minimize morbidity related to hospitalization and the post-discharge period have been proposed, especially to those aimed at reducing readmission rates. The aim of this study is to evaluate the effect of multicomponent intervention (MI) on operational indicators and continuity of care outcomes. MATERIALS AND METHODS: A quasi-experimental study conducted in a Brazilian university hospital in order to compare the impact of the intervention with usual care. The MI was the implementation of multidisciplinary rounds, the inclusion of the role of the navigator nurse, and care transition actions with half of the Internal Medicine teams in a clinical unit of a general hospital. Adult patients hospitalized were included in 2 periods and divided in 3 groups - Group A: before the intervention; Group B: after and with MI; Group C after and without MI. RESULTS: A total of 2333 hospitalizations were evaluated. There was a reduction in the rate of intensive care transfers to intensive care unit (ICU) and in the length of stay (LOS). LOS, discharge before noon, and transfers to ICU improved when comparing before and after the intervention, but were not different in post-intervention groups with and without MI. CONCLUSION: These results reflect the improvement of care provided by MI, an effect that could be due to cross contamination also to teams without the intervention.

Empowering pharmacists working in primary care through a cardiovascular disease clinical management course: Impact on practice.

INTRODUCTION: Cardiovascular disease (CVD) is currently the leading cause of mortality and morbidity worldwide. A competent healthcare workforce working in primary care delivering disease management services efficiently is the cornerstone of well performing health systems, impacting patient outcomes positively. The aim of this study was to evaluate the effectiveness of a training course to support pharmacists working in General Practitioner (GP) practices; and to evaluate its impact on practice. METHODS: A before and after evaluation model was employed to assess the effectiveness of training resorting to a survey exploring self-confidence and knowledge on clinical management of three CVD topics: Atrial Fibrillation (AF), Hypertension and hyperlipidaemia. Before and after training data (immediate and retained after 6 months) were analysed at the Primary Care Network (PCN) and GP Practice level of the pharmacists who took part in the training sessions. Data were analysed in IBM SPSS v.29 resorting to paired samples t-test and Cohen's d for estimation of the effect size. Independent samples t-tests were performed for a sample group of PCNs and GP practices with and without training (comparator group). RESULTS: An improvement with large effect size was observed in pharmacists' self-confidence and knowledge related to the hypertension topic, suggesting potential practical benefit. For the topics of AF and hyperlipidaemia, pharmacists' confidence also increased with a large effect size, but for knowledge, the effect size of the increase was medium or small. Data suggests that pharmacists' practice has improved in both groups after 6 months, which suggests that it was not a sole result of the training. CONCLUSIONS: This study provide evidence that the course improved pharmacists' knowledge and self-confidence, likely to contribute to performance in their clinical practice. Patients' clinical benefit is expected from pharmacists' improved capacity to effectively engage in medicines optimisation.

Comparative analysis of diagnostic methods and risk factors for Aelurostrongylus abstrusus infection in brazilian cats.

This study aimed to prospectively evaluate the risk factors of infection by Aelurostrongylus abstrusus in Brazilian cats with cough and/or radiographic changes, using as diagnostic tools the Baermann method (BM), polymerase chain reaction (PCR) of feces, bronchoalveolar lavage fluid (BALF), and cytology. Forty-three cats that were presented with cough or lung radiographic abnormalities compatible with bronchoalveolar disease were included in the study. After clinical evaluation, feces samples were collected to investigate lungworm parasitism through BM and PCR. BALF was performed to provide samples for cytology, bacteriology, and fungal culture. Stool PCR was considered the gold standard for diagnosis tests, and the other methods were evaluated by their agreement. PCR presented 74% (32/43) of positivity for A. abstrusus, while in the BM, 41% (18/43) were positive. BM showed sensitivity of 56.25% and specificity of 100% when compared with PCR. No larva was found in the cytological evaluation of 21 BALF samples. Lungworm is an important cause of bronchopulmonary disease in domestic cats in Brazil and should be included as a differential diagnosis when a cat is presented with cough or radiographic abnormalities. BM is a sensitive, non-invasive, and cheap technique to diagnose the disease, but it is not as sensitive as PCR.

Clinical pharmacy services in mental health in Europe: a commentary paper of the European Society of Clinical Pharmacy Special Interest Group on Mental Health.

A large proportion of the world's disease burden is attributable to mental illnesses. Although effective interventions are available, many patients still have limited access to evidence-based treatments. Aside from access, treatment gaps, including inappropriate medication selection and monitoring, are also routinely recognised. Mental health clinical pharmacists can help address these gaps and enable patients to receive optimised pharmaceutical care, particularly appropriate medication selection and monitoring. The European Society of Clinical Pharmacy (ESCP) Special Interest Group on Mental Health was established to improve standardised service provision in mental health settings across Europe. The Special Interest Group identified significant barriers (predominantly associated with reimbursement and position within the multidisciplinary team) to effective pharmaceutical care amongst those with mental illnesses. This commentary presents recommendations to address these gaps through improved mental health clinical pharmacy service provision.

Cancer care for Ukrainian refugees: Strategic impact assessments in the early days of the conflict.

BACKGROUND: The invasion of Ukraine by Russia in February 2022 has resulted in destruction of healthcare infrastructure and triggered the largest wave of internally displaced populations and refugees since World War Two. Conflicts in transitioned countries such as Ukraine create new non-communicable disease (NCD) challenges, especially for cancer care for refugees and humanitarian assistance in host countries. In the early days, rapid attempts were made to model possible impacts. METHODS: By evaluating open source intelligence used in the first three months of the conflict through snowball search methods, we aimed to address: (i) burden of cancer in Ukrainian population, specifically considering translating to the refugees population, and its cancer care capacity; ii) baseline capacity/strengths of cancer systems in initial host countries. Moreover, using a baseline scenario based on crude cancer incidence in Ukraine, and considering data from UNHCR, we estimated how cancer cases would be distributed across host countries. Finally, a surveillance assessment instrument was created, intersecting health system's capacity and influx of internally displaced populations and refugees. FINDINGS AND CONCLUSIONS: The total new cancer patients per month in pre-conflict Ukraine was estimated as 13,106, of which < 1 % are paediatric cases. The estimated cancer cases in the refugee population (combining prevalent and incident), assuming 7.5 million refugees by July 2022 and a female:male ratio of 9:1, was 33,121 individuals (Poland: 19284; Hungary: 3484; Moldova: 2651; Slovakia: 2421; Romania: 5281). According to our assessments, Poland is the only neighbouring country classified as green/yellow for cancer capacity, i.e. sufficient ablility to absorb additional burden into national health system; Slovakia we graded as yellow, Hungary and Romania as yellow/red and Moldova as red.

National trends in the use of oral chemotherapy over 13 years.

Background: Systemic cancer therapy has traditionally been administered using an intravenous (IV) route, implying patients' frequent visits to hospitals to access to their therapy. If we consider the actual pipeline in oncology, oral chemotherapy will be the main component of cancer treatment in the next few years. This shift in the administration route requires different care models in order to guarantee treatment efficacy and safety. Objective: To analyze time trends in oral chemotherapy consumption in Portugal. Method: Oral chemotherapy consumption over a 13-year period (2008-2020) was analyzed, considering dispensed units by the administration route with respective costs, resorting to the drug regulatory agency (INFARMED I.P.) database. Oral consumption patterns were further explored using common daily doses (CDD) for three conditions, including chronic myeloid leukemia (CML), non-small-cell lung cancer (NSCLC), and breast cancer (BC), to adjust for the effect of varying doses. Data were analyzed descriptively resorting to Microsoft Office Excel 2010. Results: Overall chemotherapy consumption increased +Δ54.7%, with the highest contribution in units observed in oral forms (+Δ58.8%). The total expenditure increased +Δ96.5%, and despite the increase in oral forms (+Δ221.6%), intravenous forms continued to be the major cost driver, with an important contribution from immunotherapy. Much of the increase was led by the approval of 40 new IV and 48 new oral cancer medications with higher costs introduced in the market. Using CDD as an alternative metric to units had varying impacts by indication. The observed increases seemed to focus on specific cancer sites with varying effect; in CML, there was a 2.39-fold increase, compared to 4.41 for NSCLC and 1.86 for BC. However, for BC, two distinct sub-patterns were observed for hormone therapy (increasing 1.83) and for the novel tyrosine kinase inhibitors (increasing 40.8). Conclusion: The growing use of oral chemotherapy is obvious and calls for investments in supporting patients in managing medication adherence and adverse events. The shifts in the healthcare system are complex and need to be prioritized. Our data suggest that priority could be attributed to cancer sites driving innovation, namely, advanced breast cancer.

The mediator role of unmet needs on quality of life in myeloma patients.

PURPOSE: The diagnosis of multiple myeloma (MM) has a significant impact on patients. This study analyzed the mediating role of patients' unmet needs in the relationship between psychological morbidity/social support and quality of life (QoL). METHODS: This study included 213 patients with MM recruited from the outpatient medical oncology and clinical hematology services from five hospitals. Patients who meet the study criteria were referred by physicians and invited to participate in the study by the researcher. All participants answered the following questionnaires: Hospital Anxiety and Depression Scale, Satisfaction with Social Support Scale, Short-Form Survivor Unmet Needs Survey, and The European Organization for Research and Treatment of Cancer's Multiple Myeloma Module. Descriptive statistics, bivariate correlations, and structural equation modeling were performed to analyze the data. RESULTS: The indirect effect of psychological morbidity on patients' future perspectives (MYFP) was partially mediated by information unmet needs (INF), while the indirect effect of psychological morbidity on treatment side effects (MYSE) was partially mediated by relationship and emotional unmet needs (REH). In turn, the indirect effect of psychological morbidity on disease symptoms (MYDS) was fully mediated by REH. Social support had an indirect effect on MYDS and MYSE fully mediated by REH. CONCLUSION: Intervention programs tailored to promote MM patients' QoL should specifically address information and emotional needs, raising awareness and training health professionals, caregivers, and family members to attend  MM patients' unmet needs.

Epidemiological and Pathological Characterization of Feline Injection Site Sarcomas in Southern Brazil.

Feline injection site sarcoma (FISS) is a mesenchymal neoplasm with highly malignant characteristics. These tumours originate in anatomical sites where there has been previous parenteral administration of medicinal substances or implantation of medical devices. The aim of this study was to investigate the epidemiological and pathological features associated with FISS in the southern region of Brazil. The database of the Department of Veterinary Pathology of the Federal University of Rio Grande do Sul was searched for excisional and incisional biopsy samples compatible with FISS submitted between 2007 and 2017. Biopsy reports were reviewed and epidemiological information, including breed, age and sex of affected cats, as well as gross findings including anatomical location and size of the tumour and the presence of tissue invasion, were extracted. Eighty-nine samples were selected based on the established criteria. Most animals were of undefined breed and were female cats with a median age of 10 years. Grossly, 84.8% of the tumours were >2 cm in diameter. Regarding anatomical location, 34.9% of the tumours were located in the subcutaneous tissue of the thoracic wall, 29.2% in the flank, 21.3% in the interscapular region and 14.6% in the limbs. Histologically, the tumours originated in the subcutaneous tissue and were diagnosed as malignant mesenchymal neoplasms. Most were compatible with fibrosarcomas, but variants with features of pleomorphic sarcoma or chondrosarcoma were recognized. All tumours exhibited areas of necrosis and peripheral inflammatory infiltrate, composed predominantly of lymphocytes, plasma cells and macrophages. The results of this study suggest the need for dissemination of information on FISS epidemiology and guidelines for management of this tumour to veterinarians in the region.

Manejo anestésico del síndrome de Brugada para cesárea: cuando menos es más / Anaesthetic management of C-section in Brugada syndrome: When less is more

El síndrome de Brugada (SBr) es una condición infrecuente y de alto riesgo que rara vez se encuentra en la sala de partos. Las pacientes embarazadas con SBr se benefician de las dosis más bajas posibles de fármacos arritmogénicos, como los anestésicos locales. Sobre la base de esta premisa, el siguiente caso expone cómo un abordaje subaracnoideo podría ser una técnica deseable en los procedimientos de cesárea para pacientes con SBr. El manejo del dolor y la ansiedad es prioritario en esta población específica. La planificación periparto, con una cita previa de anestesiología, y la atención multidisciplinaria en las instalaciones de hospitales terciarios son cruciales para evitar complicaciones

Brugada Syndrome (BrS) is a rare and high risk condition, seldom encountered in the delivery room. Pregnant patients with BrS benefit from the lowest possible doses of arrhythmogenic drugs such as local anesthetics. Based on this premise, the following case report exposes how a subarachnoid approach might be a desirable technique in C-section procedures for BrS patients. Pain and anxiety management are priorities in this specific population. Peri-partum planning, with a previous anesthesiology appointment and mutidisciplinary care in tertiary hospital facilities are crucial to avoid complications

Potential role of TP63 in apical periodontitis development.

AIM: To investigate the expression of TP63 in apical periodontitis (AP) tissues and the association of single nucleotide polymorphisms (SNPs) in the TP63 gene with AP using a case-control dataset. METHODOLOGY: Expression of TP63 in human AP lesions (apical abscess, radicular cyst, periapical granuloma) was evaluated using immunohistochemistry. A case-control association study was performed to assess the association of TP63 polymorphisms in individuals having AP with or without associated pain. Cases were defined as subjects with deep caries and AP (n = 151) and subjects with symptomatic apical periodontitis or acute apical abscess (n = 124). Subjects without AP (n = 169) and asymptomatic (n = 196) were used as controls, respectively. Saliva samples were collected as source of genomic DNA. Twelve SNPs in the TP63 gene were selected for genotyping using Taqman chemistry in real-time PCR. Data analysis was performed using PLINK software. The Bonferroni method was applied to correct for multiple testing; α ≤ 0.004 indicates significant differences between groups. RESULTS: TP63 expression was evident in apical abscesses and radicular cysts, while weaker expression was observed in periapical granulomas. Positive expression was observed in mononuclear cells in the granulation tissues of all AP lesions. Regarding the presence of AP, a trend for allelic association was observed for rs16864812 and rs9810322 (P = 0.04) and rs9810322 genotypes were also nominally associated with AP under a dominant model (P = 0.04). When considering the presence of periapical pain, a trend for allelic and genotypic association was observed for rs10155037 (P = 0.03). Haplotypes were also associated with AP and periapical pain (P ≤ 0.05). CONCLUSIONS: Apical periodontitis is a complex multifactorial condition and it is likely that multiple genes and environmental effects may influence its susceptibility, progression or both. TP63 variants may play a role in AP pathogenesis and susceptibility, individually or interactively with other genes. Additional studies in other populations and functional studies are needed to improve understanding of the role of TP63 in AP.

Narraciones de adolescentes con estilos de vida activos y sedentarios / Narratives of adolescents with an active and sedentary lifestyle

Nuestra investigación trata de analizar las narraciones de adolescentes que han adoptado diferentes estilos de vida e identificar las variables psicológicas, comportamentales, sociales y ambientales relacionadas con un estilo de vida activo y una vida sedentaria. Se aplicaron entrevistas de carácter narrativo a 2 niñas (1 activa y 1 sedentaria) y 2 niños (1 activo y 1 sedentario). El análisis temático ha identificado las categorías que distinguen a los dos grupos de estudiantes, a lo largo de su infancia y adolescencia, específicamente: historia de la actividad física (AF); valor de los comportamientos sedentarios; apoyo social de la familia y amigos a la AF; seguridad física y las instalaciones en el barrio; participación en AF extracurricular en la escuela; la escuela primaria y secundaria y experiencias en Educación Física (EF); profesores y compañeros de EF; conocimiento de la AF y la salud; y actitudes hacia la EF y la escuela (AU)

This study sought to analyse the narratives of adolescents who have adopted an active or a sedentary lifestyle, and to identify psychological, behavioural, social and environmental variables related to an active and a sedentary lifestyle among adolescents. Narrative interviews were conducted with 2 girls (1active and 1 sedentary) and 2 boys (1 active and 1sedentary). Thematic analysis identified a number of key personal, social and environmental influences on physical activity (PA) that distinguished the two groups of students, through their childhood and adolescence. These included PA history, the value of sedentary behaviours, social support from family and friends for PA, safety and PA facilities in the local neighbourhood, PA participation in school besides Physical Education (PE), primary and secondary school and experiences in PE, PE teachers and PE peers, PA and health knowledge and perception of PE goals, and attitudes toward school and PE (AU)

Qualitative analysis of the contributions of nutritionists to the development of an online instrument for monitoring the food intake of schoolchildren.

BACKGROUND: The Consumo Alimentar e Atividade Fisica de Escolares (CAAFE) questionnaire is an online research tool that has been developed to enable the self-report of physical activity and diet by Brazilian schoolchildren aged 7-10 years. Formative research was conducted with nutritionists during the development of the web-based questionnaire. The suggestions and insights obtained were used to design a tool to monitor schoolchildren's food consumption based on the concept of healthy and unhealthy food indicators. The present study aimed to report the focus group discussions conducted with nutritionists concerning the CAAFE questionnaire. METHODS: Focus group discussions were conducted using a semi-structured questionnaire, and these were then analysed thematically. RESULTS: Twenty-four nutritionists participated (four focus groups; average per group: six people); the majority (n = 22) had experience with 7-10-year-old children. Four themes emerged: (i) healthy and unhealthy food indicators; (ii) suggestions for the online instrument; (iii) potential applications; and (iv) challenges for its construction. CONCLUSIONS: Comments made by nutritionists enabled the construction of an instrument that is able to answer questions related to food consumption in schools and at home.

Sarcosine preconditioning induces ischemic tolerance against global cerebral ischemia.

Brain ischemic tolerance is an endogenous protective mechanism activated by a preconditioning stimulus that is closely related to N-methyl-d-aspartate receptor (NMDAR). Glycine transporter type 1 (GlyT-1) inhibitors potentiate NMDAR and suggest an alternative strategy for brain preconditioning. The aim of this work was to evaluate the effects of brain preconditioning induced by sarcosine, a GlyT-1 inhibitor, against global cerebral ischemia and its relation to NMDAR. Sarcosine was administered over 7 days (300 or 500 mg/kg/day, ip) before the induction of a global cerebral ischemia model in Wistar rats (male, 8-week-old). It was observed that sarcosine preconditioning reduced cell death in rat hippocampi submitted to cerebral ischemia. Hippocampal levels of glycine were decreased in sarcosine-treated animals, which was associated with a reduction of [(3)H] glycine uptake and a decrease in glycine transporter expression (GlyT-1 and GlyT-2). The expression of glycine receptors and the NR1 and NR2A subunits of NMDAR were not affected by sarcosine preconditioning. However, sarcosine preconditioning reduced the expression of the NR2B subunits of NMDAR. In conclusion, these data demonstrate that sarcosine preconditioning induces ischemic tolerance against global cerebral ischemia and this neuroprotective state is associated with changes in glycine transport and reduction of NR2B-containing NMDAR expression.

Vibrios in hatchery cultures of the razor clam, Solen marginatus (Pulteney).

Hatchery culture of the razor clam, Solen marginatus (Pulteney), has recently been developed in Galicia (NW Spain). However, recurrent episodes of mortalities of larval and post-larval cultures have been recorded during the course of various studies. The disease signs were similar to those described for other bivalve species in outbreaks caused by bacteria of the genus Vibrio. In this article, we present the results of microbiological monitoring of two batches of razor clams with different survival rates. All fermentative isolates were identified as members of the Splendidus clade within the genus Vibrio. Some of these isolates, identified as Vibrio splendidus-like, were clearly associated with the batch suffering mortalities, indicating their possible role as pathogens. Similar strains were found in the broodstock, suggesting vertical transmission of these bacteria. This is the first study of the microbiota associated with hatchery culture of S. marginatus, and the results will provide useful information for the optimization of a protocol for hatchery culture of this bivalve species.

The potential of secondary metabolites from plants as drugs or leads against protozoan neglected diseases - part II.

Infections with protozoan parasites are a major cause of disease and mortality in many tropical countries of the world. Diseases caused by species of the genera Trypanosoma (Human African Trypanosomiasis and Chagas Disease) and Leishmania (various forms of Leishmaniasis) are among the seventeen "Neglected Tropical Diseases" (NTDs) defined by the WHO. Furthermore, malaria (caused by various Plasmodium species) can be considered a neglected disease in certain countries and with regard to availability and affordability of the antimalarials. Living organisms, especially plants, provide an innumerable number of molecules with potential for the treatment of many serious diseases. The current review attempts to give an overview on the potential of such plant-derived natural products as antiprotozoal leads and/or drugs in the fight against NTDs. In part I, a general description of the diseases, the current state of therapy and need for new therapeuticals, assay methods and strategies applied in the search for new plant derived natural products against these diseases and an overview on natural products of terpenoid origin with antiprotozoal potential were given. The present part II compiles the current knowledge on natural products with antiprotozoal activity that are derived from the shikimate pathway (lignans, coumarins, caffeic acid derivatives), quinones of various structural classes, compounds formed via the polyketide pathways (flavonoids and related compounds, chromenes and related benzopyrans and benzofurans, xanthones, acetogenins from Annonaceae and polyacetylenes) as well as the diverse classes of alkaloids. In total, both parts compile the literature on almost 900 different plant-derived natural products and their activity data, taken from over 800 references. These data, as the result of enormous efforts of numerous research groups world-wide, illustrate that plant secondary metabolites represent an immensely rich source of chemical diversity with an extremely high potential to yield a wealth of lead structures towards new therapies for NTDs. Only a small percentage, however, of the roughly 200,000 plant species on earth have been studied chemically and only a small percentage of these plants or their constituents has been investigated for antiprotozoal activity. The repository of plant-derived natural products hence deserves to be investigated even more intensely than it has been up to present.

The potential of secondary metabolites from plants as drugs or leads against protozoan neglected diseases - part I.

Infections with protozoan parasites are a major cause of disease and mortality in many tropical countries of the world. Diseases caused by species of the genera Trypanosoma (Human African Trypanosomiasis and Chagas Disease) and Leishmania (various forms of Leishmaniasis) are among the seventeen "Neglected Tropical Diseases" (NTDs) defined as such by WHO due to the neglect of financial investment into research and development of new drugs by a large part of pharmaceutical industry and neglect of public awareness in high income countries. Another major tropical protozoan disease is malaria (caused by various Plasmodium species), which -although not mentioned currently by the WHO as a neglected disease- still represents a major problem, especially to people living under poor circumstances in tropical countries. Malaria causes by far the highest number of deaths of all protozoan infections and is often (as in this review) included in the NTDs. The mentioned diseases threaten many millions of lives world-wide and they are mostly associated with poor socioeconomic and hygienic environment. Existing therapies suffer from various shortcomings, namely, a high degree of toxicity and unwanted effects, lack of availability and/or problematic application under the life conditions of affected populations. Development of new, safe and affordable drugs is therefore an urgent need. Nature has provided an innumerable number of drugs for the treatment of many serious diseases. Among the natural sources for new bioactive chemicals, plants are still predominant. Their secondary metabolism yields an immeasurable wealth of chemical structures which has been and will continue to be a source of new drugs, directly in their native form and after optimization by synthetic medicinal chemistry. The current review, published in two parts, attempts to give an overview on the potential of such plant-derived natural products as antiprotozoal leads and/or drugs in the fight against NTDs.
