RESUMO Objetivo: Descrever casos de lesão renal aguda (LRA) em crianças diagnosticadas com COVID-19, associando fatores de risco, aspectos clínicos e evolução dos casos. Métodos: Estudo retrospectivo, realizado em hospital pediátrico entre março de 2020 e setembro de 2021, com pacientes com COVID-19 diagnosticados com LRA, que examinou informações presentes em prontuários como comorbidades, idade, sexo e uso de medicações nefrotóxicas. Resultados: Foram estudados 40 casos, sendo o sexo masculino significativamente mais acometido (62,5%; p=0,025). A LRA foi uma complicação grave da infecção por COVID-19, com 100% da amostra necessitando de internação na Unidade de Terapia Intensiva e 22,5% indo a óbito. As comorbidades mais prevalentes analisadas neste estudo foram epilepsia, paralisia cerebral e cardiopatia. A maioria dos pacientes foi classificada pelos critérios Kidney Disease: Improving Global Outcomes (KDIGO) como KDIGO 1 (42,5%) e necessitou de intubação orotraqueal (67,5%). A frequência de uso de medicamentos nefrotóxicos e necessidade de diálise foi baixa, com percentuais de 35 e 17,5%, respectivamente. Entre as crianças que faleceram, 70,4% apresentavam alguma comorbidade e 88,8% receberam ventilação invasiva. Conclusões: A LRA em crianças com infecção por COVID-19 está associada a quadros graves, apesar de a maior parte dos pacientes ter recebido alta hospitalar.

ABSTRACT Objective: To describe cases of acute kidney injury (AKI) in children diagnosed with COVID-19, associated risk factors, clinical aspects and outcome of cases. Methods: Retrospective study, carried out in a pediatric hospital between March 2020 and September 2021, with patients with COVID-19 who were diagnosed with AKI, studying information present in medical records such as comorbidities, age, gender and use of nephrotoxic medications. Results: We studied 40 cases, and male individuals were significantly more affected (62.5%; p=0.025). AKI was a severe complication of COVID-19 infection, with 100% of the sample requiring admission to the Intensive Care Unit and 22.5% dying. The most prevalent comorbidities analyzed in this study were epilepsy, cerebral palsy and heart disease. Most patients were classified according to Kidney Disease: Improving Global Outcomes (KDIGO) criteria as KDIGO 1 (42.5%), and required orotracheal intubation (67.5%). The frequency of use of nephrotoxic medications and need for dialysis was low, with percentages of 35 and 17.5%, respectively. Among the children who died, 70.4% had some comorbidity and 88.8% received invasive ventilation. Conclusions: AKI in children with COVID-19 infection is associated with severe conditions. Despite the severity, most patients were discharged alive from the hospital.

RESUMO Objetivo: Avaliar a funcionalidade e fatores associados em crianças e adolescentes com osteogênese imperfeita (OI). Métodos: Estudo transversal com 30 crianças e adolescentes com OI. Foram avaliados prontuários médicos, uso de bisfosfonatos, características socioeconômicas, dinamometria de preensão palmar, equilíbrio, hipermobilidade articular, nível de deambulação e escores do Pediatric Evaluation of Disability Inventory - Computer Adaptative Test (PEDI-CAT). Os dados foram apresentados em média e desvio padrão e comparados por teste t por Mann-Whitney, enquanto os categóricos foram apresentados em frequência e comparados pelo teste exato de Fisher. Análises intragrupos foram realizadas por análise de covariância (ANCOVA) ou Teste de Wilcoxon para postos sinalizados. O teste Tau-b de Kendall foi usado para correlações. Resultados: A idade variou de 6 a 18 anos. A amostra foi dividida em dois grupos de acordo com a gravidade da doença. Casos moderados/graves (n=10) apresentaram menor estatura e força muscular comparadas às dos leves (n=20). Fraqueza muscular foi observada em todos os casos de OI quando comparados à população normal. Não houve diferença nos domínios do PEDI-CAT com exceção do domínio mobilidade. Houve correlação entre o número de fraturas, tipo de OI, peso e equilíbrio e o domínio mobilidade; e entre os domínios Atividades Diárias e Mobilidade e Responsabilidade e Social/cognitivo do PEDI-CAT. Conclusões: Nossos achados sugerem que crianças com OI moderada/severa podem atingir o mesmo nível de funcionalidade que crianças com a forma leve. Fraturas podem ter grande influência no nível de funcionalidade e o tratamento deve enfocar a prevenção e a reabilitação desses eventos. Objetivo .

ABSTRACT Objective: The aim of this study was to evaluate the functioning and associated factors in children and adolescents with osteogenesis imperfecta (OI). Methods: This is a cross-sectional study conducted on 30 children and adolescents with OI. Medical records, use of bisphosphonates, socioeconomic status, handgrip strength, balance, joint hypermobility, ambulatory level, and the Pediatric Evaluation of Disability Inventory—Computer Adaptative Test (PEDI-CAT) scores were assessed. Data is presented as mean and standard deviation and Student’s t-test or Mann–Whitney U test. Categorical data is presented as frequency and analyzed using Fisher’s exact test. Within-group analyses were conducted using ANCOVA or Wilcoxon signed-rank test. Correlations used Kendall’s Tau-b test. Results: The participants involved in this study were 6–18 years old. The sample was separated into two groups according to disease severity. The moderate/severe OI group (n=10) presented a lower height and muscular strength than the mild group (n=20). Muscle weakness was observed in all participants with OI when compared with the normal population. No differences were observed between the groups in the PEDI-CAT scores except for the mobility domain. There were correlations between the PEDI-CAT mobility domain and the number of fractures, OI type, weight, and balance; there was also a correlation between the PEDI-CAT daily activities, mobility, responsibility, and social/cognitive domains. Conclusions: The findings suggest that children with moderate/severe forms of OI can achieve the same function levels as children with mild OI. Fractures can have a major influence on the functional level, and treatment should focus on the prevention and rehabilitation of these events when they occur. Objective .

ABSTRACT: Bovine mastitis is the most impacting disease of dairy industry, and it is characterized by a complexity of causal agents, which have revealed a geographical variation among regions and countries. The mastitis-related pathogens have been traditionally classified as contagious or environmental, based on habits of the microorganisms and transmission routes. Besides, the severity of mammary infections has been associated with the virulence of the pathogens, and immune and nutritional status of the hosts. Considering this scenario, we investigated the etiological pattern, clinical severity scores, and days in milk (DIM) data in 4,273 clinical cases of bovine mastitis among ten large-dairy farms located in Brazil. Streptococcus dysgalactiae (283/4,273 = 6.6%), Escherichia coli (190/4,273 = 4.4%), Prototheca spp. (112/4,273 = 2.6%), and Streptococcus uberis (95/4,273 = 2.2%) were the predominant pathogens isolated. Among 4,273 clinical cases, clinical severity score was available in 43.8% (1,871/4,273) animals. From these, 69.8% (1,306/1,871), 27.3% (510/1,871), and 2.9% (55/1,871) were scored as mild, moderate, and severe, respectively. Pathogens were observed mainly in samples obtained during the first 100 days in milk, and clinical severity scored mainly as mild. Our results contributed to the etiological identification, clinical severity scoring, and milking aspects of mastitic cows in dairy farms with a history of clinical mammary infections.

RESUMO: A mastite bovina é a doença mais impactante na indústria de laticínios e é caracterizada por uma complexidade de agentes causais, os quais têm revelado uma variação geográfica entre regiões e países. Os patógenos relacionados à mastite têm sido tradicionalmente classificados como contagiosos ou ambientais, com base na fonte de infecção ou origem e nas vias de transmissão. Além disso, a gravidade das infecções mamárias tem sido associada à virulência dos patógenos, e ao estado imunológico e nutricional dos animais. Considerando esse cenário, investigamos os agentes etiológicos, os escores de gravidade clínica e os dados de dias em lactação (DEL) em 4.273 casos clínicos de mastite bovina em dez fazendas de grande porte, quatro localizadas no sudoeste do estado de São Paulo e seis no sul do Estado de Minas Gerais, Brasil. Streptococcus dysgalactiae (283/4.273 = 6,6%), Escherichia coli (190/4.273 = 4,4%), Prototheca spp. (112/4.273 = 2,6%) e Streptococcus uberis (95/4.273 = 2,2%) foram os patógenos predominantes isolados. Entre os 4.273 casos clínicos, a pontuação de gravidade clínica estava disponível em 43,8% (1.871/4.273) dos animais. Desses, 69,8% (1.306/1.871), 27,3% (510/1.871) e 2,9% (55/1.871) foram classificados como leves, moderados e graves, respectivamente. Os patógenos foram observados principalmente em amostras obtidas durante os primeiros 100 dias em lactação, e a gravidade clínica foi principalmente classificada como leve. Nossos resultados contribuem para a identificação etiológica, a pontuação de gravidade clínica e os aspectos de ordenha de vacas com mastite em fazendas leiteiras com histórico de infecções mamárias clínicas.

ABSTRACT Introduction/framework/objectives Multiple Sclerosis has a reasonable prevalence and the diagnosis is generally made at working age, at a stage that is still demanding on a professional level, a time when there are also generally personal/family particularities that require some dedication. Furthermore, given the incidence, diversity and severity of the symptoms presented, limitations often arise that can seriously affect the ability to work or even lead to unemployment. It is then desirable that the members working in Occupational Health and Safety teams have some knowledge on the subject, in order to better guide their performance, safeguarding the interests of everyone involved. Methodology This is a Bibliographic Review, initiated through a search carried out in April 2023, in the databases “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina and RCAAP”. Content It is a demyelinating and autoimmune disease of the Central Nervous System; it is characterized by recurrent and intermittent episodes of inflammation, with generally progressive destruction of axonal myelin. In most cases there is a cycle of relapses and remissions and symptoms of varying intensity; the evolution is unpredictable. Causes autonomic, visual, motor and sensory symptoms; which makes independent daily living and the ability to work difficult; sometimes becoming debilitating. It is incurable and neurodegenerative. The severity varies depending on the neurological areas most affected. The function of myelin is to facilitate conduction at the level of axons; with changes in this, the electrical impulses that coordinate mental and physical functions become less effective. As myelin deteriorates, it is replaced by scars of abnormal tissue, with different consistency (stiffness, plaques), which further disrupts conduction. Injuries to the frontal and parietal lobes often result in cognitive and emotional changes; in the spinal cord, problems arise more easily in the lower limbs. Changes in the optic nerve and occipital lobe can cause visual problems. This is the neurological desease that causes most limitations in the young adult active population. Given the reasonably young age at which symptoms begin, there will be a decrease in quality of life, more significant than in other chronic diseases. Discussion and Conclusions Although the bibliography is not scarce, the emphasis in the vast majority of articles is not on Occupational Health or Safety. It would be relevant for some teams working in large companies with some prevalence, to evaluate the cases in detail, describing the main problems detected, proposed measures and their subsequent evaluation, in order to publish not only the path, but also the conclusions obtained, for greater dissemination of the subject.

RESUMO Introdução/enquadramento/objetivos A Esclerose Múltipla tem uma prevalência razoável e o diagnóstico faz-se geralmente em idade ativa, numa fase ainda exigente a nível profissional, altura essa onde geralmente também existem particularidades pessoais/familiares que necessitam de alguma dedicação. Para além disso, dada a incidência, diversidade e gravidade dos sintomas apresentados, com frequência surgem limitações que podem condicionar seriamente a capacidade de trabalho ou até levar ao desemprego. Será então desejável que os elementos a exercer em equipas de Saúde e Segurança Ocupacionais tenham alguns conhecimentos sobre o tema, de forma a melhor orientar o seu desempenho, salvaguardando os interesses de todos os envolvidos. Metodologia Trata-se de uma Revisão Bibliográfica, iniciada através de uma pesquisa realizada em abril de 2023, nas bases de dados “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina e RCAAP”. Conteúdo É uma doença desmielinizante e auto-imune do Sistema Nervoso Central; carateriza-se por episódios recorrentes e intermitentes de inflamação, com destruição de mielina axonal, geralmente progressiva. Na maioria dos casos existe um ciclo de relapsos e remissões e sintomas de intensidade oscilante; a evolução é imprevisível. Causa sintomas autonómicos, visuais, motores e sensoriais; o que dificulta a vida quotidiana independente e o trabalho, tornando-se por vezes debilitante. É incurável e neurodegenerativa. A gravidade varia com as áreas neurológicas mais atingidas. À medida que a mielina se detiora, ela é substituída por cicatrizes de tecido anormal, com diferente consistência (rigidez, placas), o que perturba ainda mais a condução. Lesões nos lóbulos frontal e parietal geralmente resultam em alterações cognitivas e emocionais; na espinal medula, mais facilmente surgem problemas nos membros inferiores. Alterações no nervo ótico e lobo occipital podem originar alterações visuais. Trata-se da doença neurológica que mais limitações causa na população ativa jovem adulta. Dada a idade razoavelmente jovem do início de sintomas, irá ocorrer diminuição da qualidade de vida, mais significativa que noutras doenças crónicas. Discussão e Conclusões Ainda que a bibliografia não seja escassa, a enfase da grande maioria dos artigos não é dada à Saúde ou Segurança Ocupacionais. Seria relevante que algumas equipas a exercer em empresas grandes e com alguma incidência, avaliassem com detalhe os casos, descrevendo os principais problemas detetados, medidas propostas e avaliação posterior das mesmas, de forma a publicar não só o caminho, mas também as conclusões obtidas, para maior divulgação do assunto.

ABSTRACT Orange peel, a physiological disorder, has been reported in Chilean sweet cherries (Prunus avium (L.) L.) after 35-45 d under modified atmosphere packaging (MAP). The ontogeny of the disorder is unknown, and preharvest factors have not been thoroughly investigated. This study involved two experiments to elucidate the association between environmental factors and the incidence of the orange peel disorder. In the first experiment, plant water potential, fruit position on the tree, relative humidity (RH), and radiation of sweet cherry trees were studied in ‘Regina’, ‘Kordia’, and ‘Lapins’. The second experiment focused on the interaction effect of heat during fruit development and the RH during storage in ‘Lapins’. The first experiment showed no clear response of orange peel incidence to natural variations in air temperature, vapor pressure deficit, and transmitted solar radiation (PPFD) within trees. However, significant differences in the incidence, severity, and timing of the disorder detection were observed among cultivars. In ‘Lapins’, orange peel disorder began before harvest in the green stage, 33.7 %, while ‘Regina’ and ‘Kordia’ showed negligible incidences of 1.25% and 0%, respectively. At postharvest, no differences were found among tree sections, either in incidence or severity of the disorder. For the second experiment, no differences in incidence were found in heated fruit during preharvest or postharvest RH treatments. However, it was observed that the higher the RH (100%), the lower the severity index (3.6) was for the orange peel disorder. The high incidence of the disorder during postharvest under natural or induced environmental conditions in the three cultivars evaluated demonstrates that RH mainly affects the orange peel disorder.

Abstract Introduction: Nursing staffing in adult intensive care has been at a ratio of two patients per nurse or one patient for one nurse. Currently, patients require complex and specialized care that provides safety and reduces Healthcare-Associated Infections. Objective: Evidencing the importance of equipping nursing personnel according to the severity of the patient compared to the nurse-patient ratio in order to reduce Healthcare-Associated Infections in patients in the adult intensive care unit. Methodology: This is a systematic review based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, conducted from September 2021 to March 2022. The databases PubMed, ScienceDirect, Epistemonikos and CUIDEN were used, and the following terms were utilized, i.e., nursing personnel, patient severity, nurse-patient ratio, healthcare-associated infections, and the Boolean operators AND, OR, and WITH. The sample consisted of 8 studies that were assessed using the Critical Reading Cards (FLC 3.0) and graded according to the National Institute for Health and Care Excellence. Results: Staffing according to patient severity compared to the nurse-patient indicator reduced healthcare-associated infections, mortality, sepsis occurrence, and medication errors.

Abstract Introduction. “Green mold,” caused by Penicillium digitatum is one of the phytosanitary issues that limits citrus production. For its control, synthetic fungicides are used, which have lost effectiveness due to resistance developed by the fungus. An alternative is the use of endophytic fungi with biocontrol action. Objective. To evaluate the effect of secondary metabolites (SM) from endophytic fungi (EF) on the mycelial inhibition of Penicillium digitatum and the effectiveness of disease control in mandarin fruits (Citrus reticulata) post-harvest. Materials and methods. The study was conducted in 2022, using a completely randomized experimental design in the Plant Health Laboratory at the Universidad Nacional de Cañete (UNDC), Lima, Peru. For the antibiosis test, secondary metabolites were extracted from ten strains of EF from the genera Trichoderma sp., Fusarium sp., and Aspergillus sp., where mycelial inhibition of the pathogen (%) was evaluated. SMs were sprayed at 15 % (v/v) concentration on mandarin fruits that were disinfected and inoculated with the pathogen by spraying (1x 105 CFU/cc). Additionally, a commercial biocontrol, a vegetable oil, and a fungicide were used. After 6 and 9 days, disease incidence (%) and severity index (0, 1, 2, 3) were evaluated. Results. Secondary metabolites from strains the HEA-111 (Aspergillus), HEA-109 (Fusarium), and HSA-1 (Trichoderma) showed the highest mycelial inhibition with 95.05 %, 87.51 %, and 47.47 %, respectively. In mandarin fruits treated with SMs from strains HEA-109 and HSA-1, there was a control of 80 % and 55 %, respectively. Conclusions. SMs from EF were effective in inhibiting the mycelial growth of P. digitatum and reduces disease progression in mandarin fruits post-harvest.

Resumen Introducción. El “moho verde” causado por Penicillium digitatum es uno de los problemas fitosanitarios que limita la producción en los cítricos. Para su control se utilizan fungicidas sintéticos, que han perdido eficacia, debido a la resistencia generada por el hongo. Una alternativa, es el uso de hongos endófitos con acción biocontroladora. Objetivo. Evaluar el efecto de metabolitos secundarios (MS) de hongos endófitos (HE) en la inhibición micelial de Penicillium digitatum y la eficacia de control de la enfermedad, en frutos de mandarina (Citrus reticulata) después de la cosecha. Materiales y métodos. El estudio se realizó en 2022, bajo un diseño experimental completo al azar, en el laboratorio de Sanidad Vegetal, Universidad Nacional de Cañete (UNDC), Lima, Perú. Para la prueba de antibiosis se extrajeron los metabolitos secundarios de diez cepas de HE de los géneros Trichoderma sp., Fusarium sp. y Aspergillus sp., en donde se evaluó la inhibición micelial del patógeno (%). Se asperjaron MS a una concentración del 15 % (v/v) sobre frutos de mandarina que fueron desinfectados e inoculados con el patógeno por aspersión (1x105 UFC/cc). Adicionalmente, se utilizaron un biocontrol comercial, un aceite vegetal y un fungicida. Después de 6 y 9 días, se evaluaron la incidencia (%) y el índice de severidad (0,1,2,3) de la enfermedad. Resultados. Los metabolitos secundarios de las cepas HEA-111 (Aspergillus), HEA-109 (Fusarium) y HSA-1 (Trichoderma) presentaron la mayor inhibición micelial con 95,05 %, 87,51 % y 47,47 %, respectivamente. En los frutos de mandarina tratados con los MS de las cepas HEA-109 y HSA-1, hubo un control del 80 % y 55 %, respectivamente. Conclusiones. Los MS de HE tuvieron efecto en la inhibición micelial de P. digitatum y redujeron el avance de la enfermedad en frutos de mandarina después de la cosecha.

Abstract Introduction. Quinoa downy mildew is a disease that causes economic losses and has been poorly studied.Therefore, researching quinoa’s response to the disease and treatment methods is a topic that requires further investigation. Objective. To describe how downy mildew infection affects quinoa plants and the non-traditional methods used to control this disease. Development. A systematic search was conducted to compile the results associated with P. variabilis in quinoa (Chenopodium quinoa Wild.) under various conditions. The analysis determined that factors such as incidence, severity, and disease tolerance depended largely on the quinoa grain variety and altitude (along with its climatic conditions). Plant height and yield per hectare were influenced by soil conditions, pest and disease treatment, and the planting day. Conclusions. The incidence and severity of downy mildew depended on the quinoa variety used. Other factors such as altitude or humidity also influenced disease progression, with infection rates close to 90 % in high humidity environments. Non-conventional methods for treating downy mildew included plant infusions such as chamomile and garlic, showing positive short-term results; however, they did not surpass conventional treatments with chemical fungicides.

Resumen Introducción. El mildiu de la quinua es una enfermedad que ocasiona pérdidas económicas y que ha sido poco estudiada, por lo que la investigación de la respuesta de la quinua a la enfermedad y las formas de tratamiento es un tema que debe investigarse con mayor profundidad. Objetivo. Describir cómo afecta la infección del mildiu velloso en la planta de la quinua y los métodos no tradicionales empleados en el control de esta enfermedad. Desarrollo. Se realizó una búsqueda sistemática a fin de realizar una recopilación de los resultados asociados al P. variabilis en la quinua (Chenopodium quinoa Wild.) en diversas condiciones. El análisis determinó que factores como la incidencia, la severidad y la tolerancia a la enfermedad del mildiu, dependieron en gran medida de la variedad de grano de quinua y la altitud (con sus condiciones climáticas). La altura de la planta y el rendimiento por hectárea estuvieron influenciados por las condiciones del suelo, el tratamiento empleado contra plagas y patógenos, y el día de siembra. Conclusiones. La incidencia y la severidad del mildiu velloso dependió de la variedad de la quinua con la que se trabajó. Otros factores como la altitud o la humedad también influyeron en el progreso de la enfermedad, con una infección cercana al 90 % en ambientes con alta humedad. Los métodos no convencionales para tratar el mildiu fueron infusiones de plantas como la manzanilla y el ajo, con resultados positivos a corto plazo; no obstante, no superaron a los tratamientos convencionales con fungicidas químicos.

Summary: The cocoa crop is very susceptible to nutritional deficiencies and moniliasis caused by the phytopathogen Moniliophthora roreri. One of the alternatives to synthetic chemicals are compounds based on silicon (Si). In the present investigation, the ef fect of silicon as a biostimulant in cocoa cultivation and as a biological control agent for M. roreri was evaluated. In the experiment, five Si treatments were used: T1 (4.00 kg ha-1), T2 (3.00 kg ha-1), T3 (2.00 kg ha-1) and T4 (1.5 kg ha-1) and a control treatment (without application). Production indicators, ear number, fresh and dry weight of almonds, dry weight of 100 almonds and crop yield were determined. In addition, the incidence and severity of the disease at 60, 120 and 180 days af ter the application of Si and the ef ficiency of the treatments. The significantly higher results for the variables: Production, ear number, fresh and dry weight of almond and dry weight of 100 almonds, were obtained by applying 4 kg ha-1 of Si, all doses of Si exceeded the control (P ≤ 0.05) in the variables related to production. In the control of the phytopathogen (M. roreri), the dose of 4 kg ha-1 Si decreased the incidence and severity of the disease by more than 50%. The application of Si can be an option in cocoa cultivation as a biostimulant and biological control agent for M. roreri.

Abstract Introduction: Erectile dysfunction (ED) is a common sexual problem among men with chronic kidney disease (CKD). The severity of sexual dysfunction tends to worsen with kidney damage. This study aims to evaluate the erectile function and sexual quality of life of adult male CKD patients undergoing hemodialysis (HD) in a hospital located in the Brazilian Amazon. Methods: A cross-sectional quantitative study was performed within the HD Sector of the Nephrology Unit including men with CKD aged ≥ 18 years, undergoing ≥ 3 weekly HD sessions for ≥ 3 months who had been sexually active for ≥ 6 months. We used the Male Sexual Quotient (MSQ) to measure sexual satisfaction and the International Index of Erectile Function (IIEF5) to establish erectile function. Statistical analysis was performed with SPSS 21.0 using appropriate tests, such as Mann-Whitney and Kruskal-Wallis (P < 0.05). Results: Ninety-eight patients (51.68 ± 15.28 years) were evaluated. They were primarily married/or living with a partner (60.20%), with HD time between 1 to 5 years (55.10%), and an average KTV of 1.17. ED prevalence was 66.30%, and it was associated with a higher age group (p = 0.01), lower family income (p = 0.02), diabetes (p = 0.01), lower mean corpuscular hemoglobin (p = 0.04), higher total calcium (p = 0.04), and lower albumin (p = 0.03). Around 75% classified their sex life as regular to excellent. Conclusion: Despite the high ED prevalence, most men with CKD in HD reported experiencing regular to excellent sex life. The study underscores the importance of establishing effective screening and conducting routine evaluations regarding sexual issues in these men. Introduction (ED CKD. .

SUMMARY OBJECTIVE: Falls are a serious cause of morbidity and mortality among older people. One of the underlying causes of falls is dehydration. Therefore, ultrasonography has become an essential tool for evaluating volume status in the emergency department. However, the effect of volume status on falls in older people has not been evaluated before. The aim of this study was to determine the relationship between the inferior vena cava collapsibility index and the injury severity score in older patients who presented with fall-related injuries to the emergency department. METHODS: A total of 66 patients were included in the study. The injury severity score was used as the trauma severity score, and the Edmonton Frail Scale was used as the frailty scale. Volume status was evaluated with inferior vena cava collapsibility index. The primary outcome measure was defined as the correlation between inferior vena cava collapsibility index and injury severity score. Secondary outcome measures were defined as the effect of inferior vena cava collapsibility index and injury severity score on hospitalization and mortality. RESULTS: There was no significant correlation between injury severity score and inferior vena cava collapsibility index (p=0.342). Neither inferior vena cava collapsibility index nor injury severity score was an indicator of the mortality of these patients. However, injury severity score was an indicator of hospitalization. The mean Edmonton Frail Scale score was an indicator of mortality among older people who experienced falls (p=0.002). CONCLUSION: Inferior vena cava collapsibility index cannot be used to predict trauma severity in older patients who have experienced falls admitted to the emergency department.

Abstract Objective To compare the effectiveness of inhaled Magnesium Sulfate associated with Salbutamol versus Inhaled Salbutamol alone in patients with moderate and severe asthma exacerbations. Method Clinical, prospective and randomized study with patients between 3 and 14 years of age divided into two groups: one to receive inhaled salbutamol associated with magnesium sulfate (GSM), the other to receive inhaled salbutamol alone (GS). The sample consisted of 40 patients, 20 patients in each group. Severity was classified using the modified Wood-Downes score, with values between 4 and 7 classified as moderate and 8 or more classified as severe. Results Post-inhalation scores decreased both in patients who received salbutamol and magnesium and in those who received salbutamol alone, with no statistically significant difference between the groups. Conclusions Despite the benefits when administered intravenously, inhalation of the drug alone or in combination did not reduce the severity of the exacerbation. exacerbations Clinical 1 groups GSM, GSM , (GSM) GS.

Abstract Background Hidradenitis suppurativa (HS) is a chronic inflammatory disease that leads to the formation of nodules, abscesses and fistulas, with the formation of scars and fibrosis, causing significant impairment in patient quality of life. The diagnosis is clinical, using scores to classify the severity of the condition; currently the most recommended classification is the International Hidradenitis Suppurativa Severity Scoring System (IHS4). Doppler ultrasound has been used to complement the clinical evaluation of patients with HS. It is possible to observe subclinical lesions that change the staging, the severity of the case, and its treatment, either clinical or surgical. Correct treatment is essential to minimize the consequences of this disease for the patient. Objective To establish an outpatient protocol for the use of Doppler ultrasound in the care of patients with HS. Methods A narrative review of the literature was carried out on the use of Doppler ultrasound in patients with hidradenitis suppurativa; a referring protocol and technique orientations for imaging assessment in HS were created. Results Recommendation to perform ultrasound evaluation of symptomatic areas eight weeks after using antibiotics and four, 12, and 24 weeks after starting immunobiologicals; apply SOS-HS ultrasound severity classification. Study limitations The review did not cover all literature on ultrasound and HS; no systematic review was carried out, but rather a narrative one. Conclusions The correct assessment of patients staging must be carried out using dermatological ultrasound to avoid progression to scars and fibrosis, which compromise patients quality of life.

Abstract Diabetes mellitus is a metabolic disease that is characterized by an increase in blood glucose levels, causing a systemic inflammatory state that can affect the healing of periapical lesions present in apical periodontitis, a chronic inflammatory disease caused by an endodontic infection whose development is regulated by the host’s immune response. Diabetes could interact with apical periodontitis by triggering immune modulation, being able to affect the clinical outcome of periapical lesions and interfering with healing after endodontic treatment. The objective of this literature review is to analyze the evidence regarding the relationship between diabetes mellitus and the presence and severity of apical periodontitis of endodontic origin. Articles were collected from the PubMed, Scopus and Web of Science databases between the years 2016 and 2021. 31 relevant articles were included for this study. In 41.6% of the studies a greater presence of apical periodontitis was found in patients with diabetes associated with a more complex and compromised apical lesion. 25% of the studies reported that poorly controlled diabetic patients had a greater presence of apical periodontitis. 25% of the studies reported high levels of HbA1c in association with apical periodontitis. A relationship was found between diabetes and apical periodontitis, which means diabetes should be considered as an important preoperative factor in the development and severity of apical periodontitis; however, more standardized experimental studies should be carried out to determine this relationship more accurately, in addition to being able to investigate a bidirectionality between the two.

Resumen La diabetes mellitus es una enfermedad metabólica que se caracteriza por tener un aumento en los niveles de glucemia, causando un estado inflamatorio sistémico que puede afectar la cicatrización de las lesiones periapicales presentes en la periodontitis apical, una enfermedad inflamatoria crónica causada por una infección endodóntica cuyo desarrollo está regulado por la respuesta inmunitaria del huésped. La diabetes podría interactuar con la periodontitis apical al desencadenar la modulación inmunitaria, pudiendo afectar la respuesta clínica de las lesiones periapicales e interferir con la cicatrización después del tratamiento endodóntico. El objetivo de esta revisión de la literatura es analizar la evidencia respecto a la relación entre la diabetes mellitus y la presencia y severidad de la periodontitis apical de origen endodóntico. Se recopilaron artículos de las bases de datos PubMed, Scopus y Web of Science entre los años 2016 y 2021. Se eligieron 31 artículos pertinentes para el estudio. En el 41,6% de los estudios se encontró una mayor presencia de periodontitis apical en pacientes con diabetes asociada a una lesión apical más compleja y comprometida. Un 25% de los estudios encontró que los pacientes diabéticos mal controlados presentan mayor presencia de periodontitis apical. Un 25% de los estudios encontró que niveles altos de HbA1c se asocian a la presencia de periodontitis apical. Se encontró una relación entre la diabetes y la periodontitis apical, por lo que la diabetes debe ser considerada como un factor preoperatorio importante en el desarrollo y severidad de la periodontitis apical, sin embargo, se deben realizar estudios experimentales más estandarizados para poder determinar con mayor exactitud esta relación, además de poder indagar la bidireccionalidad entre ambos.

Abstract Introduction: a blood transfusion is a therapeutic procedure that involves the administration of blood or its derivatives, in order to correct hematological disorders, restore hemodynamic balance or improve tissue oxygenation. It is carried out under strict protocols in order to minimize the risks of adverse transfusion reactions, considered as an unwanted and unexpected response associated with blood transfusion. Methods: descriptive study of 13,925 patients in which 67 people presented a transfusion reaction between the years 2020 to 2022. A secondary source of information was used from which the demographic and clinical variables and patients reported with transfusion reactions were taken. The information was analyzed with absolute and relative frequencies and their 95% confidence interval. Results: during 2020-2022, 67 adverse reactions related to the transfusion of 53,418 blood components were reported. Allergic reactions were the most common 85.07% (95% CI 74.26-92.60). Regarding the severity of the reaction, most people had a mild reaction 63.64% (2020), 81.50% (2021), 79.30% (2022). The prevalence for the female sex was higher 63.64%, 59.3% and 62.1% and for the age of people between 18 to 59 years old 54.55%, 44.44% and 37.9% respectively. Conclusion: blood transfusion plays a crucial role in various clinical contexts. Worldwide, adverse events affect between 1% and 3% of transfused patients. In Colombia, they affect 0.12%, the same as in this study where 0.12% presented an adverse transfusion reaction. This shows an under-registration at the national level, raising questions about their quality and timeliness.
