La complejidad de Medellín en el horizonte de la modernidad (1930-1950): tensiones, imaginarios y conflictos. Una lectura de ciudad en el discurso de Juan José Hoyos Naranjo
Authors: González Rodríguez Luz Dory
Published: May 2024

Se considera abordar el análisis de la crónica La última muerte de Guayaquil (1984)[1] del periodista, investigador y escritor Juan José Hoyos Naranjo[2], para relevar la propuesta de corte temporal y hacer una lectura crítica de ella desde la óptica del pensamiento complejo, prestando atención al recorrido trazado por el autor del que se ocupa este estudio y las resonancias de ese camino en un contexto histórico. Dicho análisis se desarrollará en torno a tres ejes: primero, la representación de la ciudad de Medellín como espacio urbano central, en el marco del proceso de éxodo campesino que atravesó Colombia y el Departamento de Antioquia entre 1930 y 1950. Segundo, la manera como ha sido abordado este género en los estudios literarios y periodísticos latinoamericanos que posibilita identificar, en el discurso de Hoyos, procedimientos formales del momento transicional de principios de siglo xx (léase 1930). Por último, las consideraciones que desvendan el establecimiento literario epocal —Juan José Hoyos visto como escritor de periodismo narrativo cuyo trabajo focaliza  en la investigación de la ciudad de Medellín de finales del siglo xix hasta mediados del siglo xx— y la ubicación del proyecto intelectual y escritural de Hoyos en el periodismo colombiano del siglo xxi.

Background and Objectives: Septic arthritis is an uncommon condition in neonates. It is a serious disorder, especially because of the possibility of sequelae, if not identified and treated early. In addition, due to the rarity of this condition in neonates and the paucity of signs and symptoms, the diagnosis of septic arthritis is more difficult in older children. The published literature is limited to case series, which is why the purpose of this systematic review is to provide a comprehensive summary of neonatal septic arthritis based on the existing literature. This study identifies the changing trends over time, specifically focusing on intravenous cannulation as a major risk factor that led to the undertaking of the study. Methods: The preferred reporting items for systematic reviews and meta-analyses protocol guidelines were used in this study. Three search engines were used for 239 articles. A total of 26 studies were screened in full text, of which 16 articles underwent quantitative analysis. Due to limited data and heterogeneous reporting, the data were summarized descriptively. Results: The total number of babies and joints studied was 307 and 313, respectively, of which the proportion of male babies was mentioned in 12 case series, accounting for 136(228) (60% [42%-71%]) subjects. The most common presenting symptoms were swelling at the involved joint, erythema, and decreased range of motion in variable order. The most common site of involvement was the hip joint (42%), followed by the knee joint (27%). Staphylococcus aureus (40%) was the most commonly cultured pathogen, followed by Klebsiella (18%). Antibiotics were reported in only 12% (38 babies) of the cases. Open surgery was performed on 16% of the 49 babies. The rest of the babies responded to joint aspiration and irrigation, with or without immobilization. Prompt laboratory and radiographic evaluations could help reduce delays in diagnosis and improve outcomes. Blood and tissue cultures were positive in most of the cases. Previous culture reports for the same unit guide the addition of empirical antibiotics. Conclusions: In our case series, the majority of the babies were premature. The most common joint involved is the hip joint. The most common underlying cause is sepsis and catheterization. Intravenous canulation is also a major risk factor because of the continuity of metaphysis and epiphysial vessels. The most common presenting symptom is local signs. Unexplained fever and irritability make it better to look for a local examination of joints. Follow-up is mandatory as a long-term sequel is more.

Background: Spinal muscular atrophy (SMA) is a neuromuscular disorder that is highly frequent in children. This leads to serious health challenges for children of different severity levels. Orem’s self-care deficit nursing theory helps parents get involved in their child’s care, leading to better outcomes and healthcare experiences. Accordingly, this case study examines the effectiveness of applying Orem’s self-care nursing theory to a child with SMA and his parents. Case Presentation: This study used Orem’s self-care deficit nursing theory to treat particular self-care deficiencies relating to mobility, eating, swallowing, and respiratory function in a 3-year-old child with SMA type I. The researcher recognized the patient’s lack of self-care and created a tailored plan for self-management training. The initial steps were to understand the patient’s needs, organize the implementation, and create the educational system. The final phase entailed implementing the self-care program and assessing its success. The following methods were used to gather the data: Structured interviews and surveys on Orem’s theory and self-care ability. A 60-min educational intervention was broken up into four in-person sessions. This study illustrates the useful application of theories in illness management. This theory was used to identify deficiencies in movement, feeding, swallowing, and respiratory function. Nursing interventions focused on neuromuscular deficits, while educational interventions enhanced parents’ awareness. Conclusions: This case study investigates the usefulness of Orem’s theory in controlling SMA, empowering parents, emphasizing patient-centered care, and the possible advantages of nursing theories in treating chronic diseases.

Background and Objectives: Failure to thrive (FTT) is a common developmental disorder in infants. Although the improvement effect of zinc supplementation in these patients was reported in some past studies, the results were conflicting. Accordingly, this study investigates the effect of zinc supplementation on factors related to growth in infants with FTT by conducting a meta-analysis. Methods: Medline, Web of Science, and Scopus databases were comprehensively searched to find randomized controlled trials investigating the effect of zinc on growth-related factors in infants with FTT. Eligible studies were extracted after screening their relevant information. The pooled effect size was estimated as a weighted mean difference with a 95% confidence interval (CI) using the random effect model method. Results: Out of 85 reviewed papers, 4 studies were eligible to enter this review. The present meta-analysis revealed that zinc supplementation in infants with FTT led to a significant increase in weight (weighted mean difference (MD)=-0.25 kg; 95% CI, 0.02%-0.49%), weight-for-age Z-score (weighted MD=0.16; 95% CI, 0.03%, 0.28%), and height-for-age Z-score (weighted MD=0.15, 95% CI, 0.001%, 0.30%), compared to control groups. In contrast, zinc supplementation had no significant effect on height and insulin-like growth factor 1 serum level. Conclusions: The findings of the current meta-analysis indicated the effectiveness of zinc supplementation in improving the developmental status of infants with FTT; however, due to the small number of included trials, it was impossible to draw definitive conclusions, and conducting randomized controlled trials with larger sample size and higher sensitivity is needed.

Context: Childhood pre-obesity and obesity rates have been rapidly growing worldwide over the past decades. Copper homeostasis is gaining increasing attention in the physiopathology of obesity. Strong evidence indicates that a disturbance of copper homeostasis plays an important role in the development of obesity and its related comorbidities. Under physiological conditions, copper plays a significant role in regulatory, immunologic, and antioxidant functions resulting in protection against inflammation and oxidative stress, and consequently against the known comorbidities of obesity. Nevertheless, despite the growing body of research, information about copper status in obesity, particularly in childhood obesity, is scarce. Evidence Acquisition: This brief narrative review examines the latest data published in the last five years using various databases, such as PubMed, Scopus, Unpaywall (COBISS), and EBSCO to emphasize the major current findings in research related to this topic. Results: The most recent studies have yielded strong evidence in support of altered copper status in childhood obesity; nevertheless. Conclusions: Further studies are needed to clarify the role of copper in the physiopathology of childhood obesity.
