Clinical characteristics of neonatal and infant osteomyelitis and septic arthritis: a multicenter retrospective study

Abstract Objective: Signs and symptoms of osteomyelitis or septic arthritis in neonates and infants are often nonspecific and early-stage bone infections in infants may often go unnoticed. The objective of this study was to analyze the clinical characteristics of newborns and infants with osteomyelitis and septic arthritis to improve understanding of the disorder and to assist clinicians with diagnosis. Methods: A retrospective multicenter study was conducted on neonates (0-28 days old, n = 94) and infants (1-12 months old, n = 415) with osteoarticular infections. Data consisting of clinical characteristics, complications, laboratory outcomes, and the pathogenic microorganisms causing osteomyelitis were tabulated. The statistics were further broken down into two regions and the significant differences between neonates and infants were evaluated and compared to the literature. Results: Compared to infants, neonates had significantly lower incidences of fever (p < 0.0001), higher incidences of localized swelling (p = 0.0021), higher rate of infection at the humerus (p = 0.0016), higher percentage of Escherichia coli (p < 0.0001) and Klebsiella pneumoniae (p = 0.0039) infections, lower percentage of Staphylococcus aureus infections (p < 0.0001) and were more likely to develop septic arthritis (p < 0.0001). Conclusion: Distinct differences were found between neonatal and infants with osteoarticular infections. Future studies should focus on improving diagnosis and subsequent treatment regimens for younger age groups.

Body Composition Classification with Electrical Bioimpedance in Chilean Military by Sex / Clasificación de la Composición Corporal con Bioimpedancia Eléctrica en Militares Chilenos por Sexo

SUMMARY: Military readiness relies heavily on the physical fitness and operational capability of its personnel. This study aims to enhance the effectiveness of body composition assessment and classification protocols within the military context. A comprehensive evaluation of 4370 active-duty Chilean military personnel was conducted, focusing on anthropometric characteristics, including adipose tissue, muscle tissue, and anthropometric indices. The study observed significant differences in body composition between genders, with men exhibiting lower levels of body fat percentage (men: 26.28 %; women: 34.62 %) but higher levels of muscle mass (men: 42.0 %; women: 36.0 %;), skeletal muscle index (men:11.81; women: 9.31), and fat-free mass index (men: 19.92; women: 18.45) compared to women. High levels of muscle tissue were observed in both groups. By integrating these findings into a standardized assessment protocol, a more accurate classification of military personnel was achieved, surpassing traditional methods used in sedentary obese populations. The study advocates the future adoption of an assessment model based on artificial intelligence (AI) algorithms, which consider the multifaceted nature of body composition and its impact on operational capability. Such a model would enable military forces to optimize their personnel's physical fitness and readiness, thus enhancing their effectiveness in deployment operations.

La preparación militar depende en gran medida de la aptitud física y la capacidad operativa de su personal. Este estudio tiene como objetivo mejorar la eficacia de los protocolos de evaluación y clasificación de la composición corporal dentro del contexto militar. Se realizó una evaluación integral de 4.370 militares chilenos en servicio activo, centrándose en las características antropométricas, incluido el tejido adiposo, el tejido muscular y los índices antropométricos. El estudio observó diferencias significativas en la composición corporal entre sexos, con los hombres exhibiendo niveles más bajos de porcentaje de grasa corporal (hombres: 26,28 %; mujeres: 34,62 %) pero niveles más altos de masa muscular (hombres: 42,0 %; mujeres: 36,0 %;), índice de músculo esquelético (hombres: 11,81; mujeres: 9,31) e índice de masa magra (hombres: 19,92; mujeres: 18,45) en comparación con las mujeres. Se observaron altos niveles de tejido muscular en ambos grupos. Al integrar estos hallazgos en un protocolo de evaluación estandarizado, se logró una clasificación más precisa del personal militar, superando los métodos tradicionales utilizados en poblaciones obesas sedentarias. El estudio aboga por la adopción futura de un modelo de evaluación basado en algoritmos de inteligencia artificial (IA), que consideren la naturaleza multifacética de la composición corporal y su impacto en la capacidad operativa. Un modelo de este tipo permitiría a las fuerzas militares optimizar la aptitud física y la preparación de su personal, mejorando así su eficacia en las operaciones de despliegue.

Undervalued tuna meat (Thunus obesus and Katsuwonus pelamis lineaus) to develop sausages / Carne infravalorada de atún (Thunnus obesus y Katsuwonus pelamis linnaeus) para desarrollar salchichas

Background: The tuna industry is one of the most essential sectors in global food production. Nevertheless, commercial meat known as "tuna loin" holds the utmost significance in producing and marketing its various products. Regrettably, fractions like tail and head meat have been overlooked and wasted due to their comparatively lower commercial value. Despite possessing notable technological value, this meat is typically reutilized into animal feed through flour production, missing the chance to create alternative high-value food products. Objective: This study aimed to develop and evaluate the sausages produced with the underutilized cuts of tuna (tail and head meat). Methods: The tuna utilized were Big-eye (Thunus obesus) and Skip-jack (Katsuwonus pelamis lineaus). Three (3) different types of sausages were formulated using 100% of Big-eye (BE), 100% of Skip-jack (SJ) tuna meat, and 100% of beef/pork meat (Control). The sausage pH changes during storage at 4 ± 1oC were analyzed and compared with the control. Proximal, microbiological, and sensory characteristics were evaluated. Results: The pH of sausages showed that the values tended to decrease in control, while this value increased in two types of tuna. The formulated tuna sausages yielded 72% moisture, 18% protein, 4.1% lipid, 0.4% ash, 0.4 % fiber, and 4.5% carbohydrates. Sensory attributes showed excellent acceptance regarding color, smell, flavor, and texture. Overall acceptability was qualified as "liked," and the acceptability index ranged from 76% to 86%. During the refrigeration storage, the microbiological analyses indicated that the total coliform count was < 3 CFU/g. Escherichia coli, Staphylococcus aureus, and mesophilic aerobic bacteria in tuna sausage showed absence during 24 days of storage. Conclusion: Using tuna tail and head meat enabled the development of gel-type emulsified products (sausages) that exhibited good nutritional, sensory, and microbiological quality

Antecedentes: La industria atunera se erige como uno de los sectores más importantes en la producción mundial de alimentos. Sin embargo, entre sus diversos productos, la carne comercial conocida como "lomo de atún" ostenta la mayor importancia tanto en su producción como en su comercialización. Lamentablemente, fracciones de carne provenientes de la cola y la cabeza se han desperdiciado debido a su reducido valor comercial. A pesar de poseer un notable valor tecnológico, esta carne normalmente es utilizada en la alimentación animal mediante la producción de harina, perdiendo la oportunidad de desarrollar productos alimenticios alternativos con alto valor nutricional. Objetivo: Este estudio tuvo como objetivo desarrollar y evaluar salchichas producidas con carne subutilizada de atún (carne de cola y cabeza). Métodos: Las especies de atún utilizadas fueron Big-eye (Thunus obesus) and Skip-jack (Katsuwonus pelamis lineaus). Se formularon tres (3) tipos diferentes de salchichas usando 100 % de carne de atún Big-eye (BE), 100 % de Skip-jack (SJ) y 100 % de carne de res/cerdo (Control). Se analizaron los cambios de pH en las salchichas durante el almacenamiento a 4 ± 1 oC y se compararon con el Control. También se evaluaron la composición proximal, calidad microbiológica y atributos sensoriales. Resultados: El pH mostró que los valores tendieron a disminuir en relación a la muestra Control, mientras que este valor aumentó en los dos tipos de salchicha con carne de atún. Las salchichas con carne de atún mostraron un 72 % de humedad, 18 % de proteína, 4,1 % de lípidos, 0,4 % de ceniza, 0,4 % de fibra, 4,5 % de carbohidratos. Los atributos sensoriales mostraron buena aceptabilidad de los parámetros de color, olor, sabor y textura. La aceptabilidad general se calificó como "me gusta" y el índice de aceptabilidad osciló entre el 76 % y el 86 %. Durante el periodo de almacenamiento en refrigeración, los análisis microbiológicos indicaron que el recuento de coliformes totales fue < 3 UFC/g. No se evidenció la presencia de Escherichia coli, Staphylococcus aureus y bacterias aerobias mesófilas durante 24 días de almacenamiento. Conclusión: El aprovechamiento de la carne de la cola y cabeza del atún permitió desarrollar productos emulsionados tipo gel (embutidos) que exhibieron buena calidad nutricional, sensorial y microbiológica.

A 50 años de la exclusión de la homosexualidad del Manual diagnóstico y estadístico de los trastornos mentales (DSM) / 50 years after the exclusion of homosexuality from the Diagnostic and Statistical Manual of Mental Disorders (DSM)

RESUMEN Se cumple medio siglo del hecho histórico constituido por la remoción de la homosexualidad como ítem diagnóstico en la clasificación norteamericana de trastornos psiquiátricos, es decir, en el Manual diagnóstico y estadístico de los trastornos mentales (DSM). Aunque es un período breve, cuesta trabajo creer que, hasta hace 50 años, las personas homosexuales carecían de numerosos derechos civiles elementales en EE. UU. y que diversas leyes penalizaban actos sexuales privados y libremente consentidos entre adultos. Rememorar estos hechos significativos en el contexto de una acotada reseña de la historia conceptual de la homosexualidad como trasfondo es el objetivo fundamental de este artículo que, a la vez, constituye un recordatorio de muchas tareas pendientes en la salud mental y derechos humanos de las minorías sexuales, todavía víctimas de homofobia, estigma y segregación, más aún en países como el nuestro.

ABSTRACT It is half a century since the historical event constituted by the removal of homosexuality as a psychiatric diagnosis from the North American Diagnostic and Statistical Manual of Mental Disorders (DSM). Although it is a short period of time, it is hard to believe that fifty years ago, homosexual people lacked many basic civil rights in the United States and various laws criminalized private, freely consented sexual acts between adults. Recalling these significant events in the context of a summarized conceptual history of homosexuality is the main objective of this brief account which, at the same time, can serve as a reminder of many tasks pending in the mental health and human rights of sexual minorities, still victims of homophobia, stigma, and segregation, even more so in countries like Peru.

Objective To analyze the seasonal and epidemiological characteristics of community-acquired pneumonia (CAP) in Chuzhou from 2010 to 2022. Methods The epidemiological data of CAP in Chuzhou from 2010 to 2022 were obtained from the center for diseases control and prevention of Chuzhou City, Anhui Province. After inclusion and exclusion, a total of 1 053 cases were enrolled. General data were collected. Then the characteristics of CAP patients in terms of gender, age, regional and seasonal distribution and pathogenic bacteria distribution were analyzed. Results A total of 316 patients with CAP, with a prevalence rate of 30.01%, including 152 males (48.10%) and 164 females (51.90%). Regarding age, 86 cases (27.22%) at 19-40 years, 106 cases (33.54%) at 41-60 years, and 124 cases (39.24%) at >60 years, suggesting a statistical difference in the CAP detection rate among different genders and ages (P<0.05). Seasonally, 118 cases (37.34%) were detected in spring, 13 cases (4.11%) in summer, 49 cases (15.51%) in autumn, and 136 cases (43.04%) in winter, with the highest CAP detection rate in winter, followed by spring. Pathogenic bacteria were positive in 198 of 316 patients, with a detection rate of 62.66%. A total of 125 strains of pathogenic bacteria were detected in sputum culture, of which 138 cases were Gram-negative, mainly Escherichia coli (24.24%, 48/198), and 60 cases were Gram-positive, mainly Streptococcus pneumoniae (14.14%, 28/198). Among 198 patients positive for pathogen detection, 41 cases were detected in spring, 37 cases in summer, 56 cases in autumn and 64 cases in winter. The drug sensitivity results showed that Escherichia coli had the highest resistance rate to ampicillin and cefazolin, and was sensitive to imipenem and other antibiotics; Streptococcus pneumoniae has the highest resistance rate to penicillin and erythromycin, and is sensitive to vancomycin. Conclusion CAP is quite common in elderly population in Chuzhou from 2010 to 2022, with a high prevalence rate in spring and winter, and the prevention work of high-risk groups should be strengthened.

Clinical Characteristics and Potential Risk Factors Analysis of Liver Injury Related to Epimedii Folium Preparation / 中国实验方剂学杂志

ObjectiveThis paper aims to analyze the clinical characteristics and medication rationality of liver injury related to Epimedii Folium preparation （EP） and explore the possible risk factors of liver injury， so as to provide a reference for the safe clinical application of Epimedii Folium （EF）. MethodA retrospective analysis was conducted on liver injury cases related to EP from 2012 to 2016. ResultThe number of reported liver injury cases and the proportion of severe cases related to the use of EP show an increasing trend， indicating the objective existence of liver injury caused by EP. There are more cases of liver injury related to EP in women than in men， with an onset age range of 15-91 years old and a median onset age of 60 years old （median onset ages for men and women are 59 and 60 years old， respectively）. The time span from taking EP alone to the occurrence of liver injury is 1-386 days， with a median of 38 days. The time span from taking both EP and Western medicine to the occurrence of liver injury is 1-794 days， with a median of 34 days. EF-related liver injury preparations are mostly composed of traditional Chinese medicines that promote immunity and tonify the liver and kidney， indicating that immune stress in the body may be the mechanism of liver injury caused by the use of EP alone or in combination. There is no increasing trend of toxicity with time or dose in the liver injury caused by EP. By further exploring its risk factors， it is found that patients have unreasonable medication methods such as excessive dosage， repeated use， and multi-drug combination， which may also be one of the important risk factors for EF-related liver injury. ConclusionEP has a certain risk of liver injury and should be emphasized in clinical diagnosis and treatment. Immune stress may be the mechanism of liver injury caused by EP， and in clinical use， it is necessary to be vigilant about the risk of liver injury caused by unreasonable use and combined use with Western medicine.

Fitting Degrees of Animal Models of Diarrhea-irritable Bowel Syndrome with Clinical Characteristics of Western Medicine and Traditional Chinese Medicine / 中国实验方剂学杂志

Diarrhea-irritable bowel syndrome （IBS-D） is one of the common functional bowel diseases in clinical practice. Since it pathogenesis is complex and has not been fully elucidated， effective treatment methods remains to be developed for this disease. Establishing the animal models of IBS-D in accordance with the clinical characteristics of traditional Chinese medicine （TCM） and Western medicine helps to reveal the pathogenesis of this disease and improve the treatment plan. The fitting degree of an animal model with clinical characteristics is an indicator to evaluate the effectiveness of the animal model in simulating the disease characteristics of Western medicine and the syndromes of TCM based on the latest diagnostic standards. By reviewing the relevant articles about the animal models of IBS-D， we discovered that rats were the preferred animals for modeling， and the models were mainly induced by single factors， double factors， or the combination of multiple factors. The established animal models mainly present symptoms or signs associated with visceral hypersensitivity or/and gastrointestinal motility abnormalities. The single factor-induced rat models of IBS-D had high fitting degrees with the clinical characteristics of Western medicine but low fitting degrees with the TCM syndromes. The animal models induced by two or more factors had high but varied fitting degrees with the clinical characteristics of Western medicine. In addition， the animal models of IBS-D considering TCM syndromes mainly focuses on the syndrome of liver depression and spleen deficiency， and few models were established for the syndromes of spleen-kidney Yang deficiency， spleen-stomach dampness-heat， spleen deficiency and dampness excess， and cold and heat in complexity. Therefore， it is essential to improve the existing or develop new animal models of IBS-D in the future， so as to provide more tools for deciphering the mechanisms of TCM and Western medicine and developing treatment methods for this disease.

Hepatitis E virus infection in liver transplant recipients / 器官移植

Hepatitis E virus infection is a common cause of acute viral hepatitis. In recent years, the incidence of hepatitis E has shown an increasing trend, which has gradually become an important cause of acute viral hepatitis worldwide. Age, sex, intensity of immunosuppression and socio-economic factors are all risk factors for hepatitis E virus infection. Liver transplant recipients require long-term use of immunosuppressive drugs for anti rejection treatment, prone to hepatitis E virus infection and at the risk of liver fibrosis and cirrhosis due to immunosuppression status. Therefore, special attention should be paid to liver transplant recipients in clinical practice. Meantime, related risk factors should be identified to assist diagnosis and take stricter preventive measures. According to literature review, the etiological characteristics of hepatitis E virus and the epidemiological characteristics, clinical manifestations, diagnosis and treatment of hepatitis E virus infection in liver transplant recipients were reviewed, aiming to properly monitor, treat and prevent hepatitis E virus infection in liver transplant recipients in clinical practice, improving the prognosis of liver transplant recipients.

Genetic characteristics of influenza A H3N2 virus influenza season in Xiangyang City in 2022-2023 / 公共卫生与预防医学

Objective To analyze the prevalence and genetic characteristics of influenza A(H3N2) viruses in the city of Xiangyang in 2022-2023, and to provide a scientific basis for predicting the epidemic and mutation of influenza virus. Methods Throat swab specimens of the influenza like cases were collected from national influenza monitoring sentinel hospitals in Xiangyang every week. RNA was extracted from the specimens for influenza diagnosing using real-time RT-PCR．Viruses were isolated from H3N2 positive specimens, and HA and NA genes were amplified and sequenced．3D modeling analyses were conducted. Results The gene phylogenetic tree showed that the H3N2 isolates in 2022-2023 belonged to 3C.2a1b.2a1 and 3C.2a1b.2a2 branches, respectively. The A(H3N2) influenza virus strains all had amino acid point mutation sites on important antigenic determinants of HA protein. The epitope mutations of the 2022 A(H3N2) strain mainly occurred in regions B, C, and D. The epitope mutations of the A(H3N2) strain in 2023 mainly occurred in regions C and D. Different glycosylation sites of HA gene were found in 2022-2023 strains. No variation was found in key amino acid sites associated with neuraminidase inhibitor resistance. The difference of overall structure was not obvious in the three-dimensional simulation structure diagram. Conclusion The A(H3N2) influenza strains isolated in this study have shown antigenic drift, especially the mutation of HA, which may affect the protective effect of the vaccine on the local population and lead to influenza epidemic. The variations of HA and NA suggest that close attention should be paid to the epidemic and genetic variation of H3N2 subtype influenza virus, to provide a scientific basis for the selection of influenza virus vaccine strains and the prevention and control of influenza.

Genomic characteristics analysis of a colistin and tigecycline-resistant Klebsiella pneumoniae / 公共卫生与预防医学

Objective In this study, a strain of colistin and tigecycline-resistant bacteria isolated in 2009 was analyzed, and the structure of drug-resistant plasmid and genetic environment were discussed, so as to provide basis for the prevention and control of multidrug-resistant bacteria. Methods A strain (GZ12244) with positive mcr and tet(M) was obtained by screening colistin and tigecycline resistance genes. Vitek-2 was used for strain identification, and the drug sensitivity test was carried out by broth dilution method. The molecular typing, drug resistance genes, insertion sequences, plasmid structure and genetic background were analyzed by genome-wide sequencing and bioinformatics. Results Strain GZ12244 is Klebsiella pneumoniae, which is resistant to colistin B, tigecycline, cefuroxime and tetracycline, and carries a variety of drug-resistant related genes such as mcr-1 and tet(M), and some of the drug-resistant genes with antibiotic efflux and antibiotic target change have amino acid substitution mutations. Mcr-1 and tet(M) coexist in a plasmid, and mcr-1 flanked by two insertion sequences ISApl1. There are insertion sequences such as IS15, IS1D and ISEc63 in the upstream and downstream of tet(M) gene. Conclusion Klebsiella pneumoniae GZ12244 is a multidrug-resistant strain. The drug-resistant gene exists in plasmid, and the mobile elements in upstream and downstream may spread the drug-resistant gene.

Multi-scale spatiotemporal characteristics of the clustered epidemics in primary and secondary schools and kindergartens in Hongshan District, Wuhan City / 公共卫生与预防医学

Objective To analyze the spatiotemporal characteristics of the clustered epidemics of common infectious diseases in primary and secondary schools and kindergartens in Hongshan District, Wuhan from 2015 to 2022, and to provide a basis for scientific development of control measures. Methods Descriptive epidemiological methods were used to describe events. Mean center method and standard ellipse method were used to reflect the overall distribution characteristics of the events, and hot spot analysis and nuclear density analysis were used to explore and analyze the spatiotemporal characteristics of clustered epidemics at annual and seasonal scales. Results From 2015 to 2022, a total of 1563 clustered outbreaks of infectious diseases were reported in primary and secondary schools and kindergartens in Hongshan District of Wuhan. The top three clustered epidemic diseases were hand-mouth-foot disease (HFMD)/herpangina, influenza like cases, and varicella, respectively. Primary schools were prone to influenza like cases (76.00%), kindergartens were prone to HFMD/herpangina (92.06%), and primary schools and middle schools were prone to varicella (69.70% and 21.21% respectively). As the years grew, the clustered epidemics showed a trend of spreading towards the northeast and southwest direction. Compared with other places, Luonan Street and Hongshan Street had a higher incidence density of clustered epidemic events (21.81% and 15.86% respectively), which requires special attention. The areas with the highest nuclear density value in each season were mainly concentrated in the middle of Hongshan District. There were two clusters of HFMD/herpangina concentrated in Luonan Street, Liyuan and Heping Street, which was different from other diseases. Conclusion When deploying medical resources and epidemic prevention and control work in schools within the jurisdiction, more emphasis should be placed on key streets and places to achieve the best cost-effectiveness.
