Risk factors for 30-day hospital readmission in patients with diabetic foot.

INTRODUCTION: Diabetic foot (DF) is part of the natural history of diabetes mellitus, ulceration being a severe complication with a prevalence of approximately 6.3 %, which confers a significant economic burden. Hospital readmission in the first thirty (30) days is considered a measure of quality of healthcare and it's been identified that the most preventable causes are the ones that occur in this period. This study seeks to identify the risk factors associated with readmission of patients with DF. METHODS: A case-control study was done by performing a secondary analysis of a database. Descriptive statistics were used for all variables of interest, bivariate analysis to identify statistically significant variables, and a logistic regression model for multivariate analysis. RESULTS: 575 cases were analyzed (113 cases, 462 controls). A 20 % incidence rate of 30-day readmission was identified. Statistically significant differences were found in relation to the institution of attention (Hospital Universitario de la Samaritana: OR 1.9, p value < 0.01, 95 % CI 1.2-3.0; Hospital Universitario San Ignacio: OR 0.5, p value < 0.01, 95 % CI 0.3-0.8) and the reasons for readmission before 30 days, especially due to surgical site infection (SSI) (OR 7.1, p value < 0.01, 95 % CI 4.1-12.4), sepsis (OR 8.4, p value 0.02, 95 % CI 1.2-94.0), dehiscence in amputation stump (OR 16.4, p value < 0.01, 95 % CI 4.2-93.1) and decompensation of other pathologies (OR 3.5, p value < 0.01, 95 % CI 2.1-5.7). CONCLUSION: The hospital readmission rate before 30 days for our population compares to current literature. Our results were consistent with exacerbation of chronic pathologies, but other relevant variables not mentioned in other studies were the hospital in which patients were taken care of, the presence of SSI, sepsis, and dehiscence of the amputation stump. We consider thoughtful and close screening of patients at risk in an outpatient setting might identify possible readmissions.

[Ambulatory blood pressure monitoring, adult and pediatric population. A narrative review]. / Monitorización ambulatoria de la presión arterial en adultos y población pediátrica. Una revisión narrativa.

Hypertension has become a central risk factor for the development of cardiovascular disease, underscoring the importance of its accurate diagnosis. Numerous studies have established a close relationship between elevated systolic (SBP) and diastolic (DBP) blood pressure and an increased risk of cardiovascular event (CVE). Traditionally, blood pressure (BP) measurements performed in clinical settings have been the main method for diagnosing and assessing hypertension. However, in recent years, it has been recognized that BP measurements obtained outside the clinical setting, using self-monitoring blood pressure (SMBP) and ambulatory blood pressure monitoring (ABPM), offer a more realistic perspective of patients' daily lives and therefore provide more reliable results. Given the evolution of medical devices, diagnostic criteria, and the increasing relevance of certain components of ABPM in the prediction of adverse cardiovascular outcomes, a comprehensive update that is practical for daily clinical practice is required. The main objective of this article is to provide an updated review of ABPM, focusing on its importance in the evaluation of hypertension and its impact on public health in Colombia. In addition, it will discuss the implications of changes in diagnostic thresholds and provide concrete recommendations for the effective implementation of ABPM in clinical practice, allowing health professionals to make informed decisions and improve the care of their patients.

Treatment of obstructive sleep apnea after chemoradiation therapy for advanced head and neck cancer.

This report presents a case of worsening obstructive sleep apnea (OSA) post-chemoradiation therapy that improved significantly after placement of a hypoglossal nerve stimulator. The patient was a 66-year-old male, diagnosed with head and neck cancer, who experienced exacerbation of OSA after receiving chemoradiation. A hypoglossal nerve stimulator was placed, with minimal complications. The patient showed a significant improvement in OSA as exhibited by the reduction in apnea-hypopnea index. Hypoglossal nerve stimulator placement appears to be a potential treatment option for induced or worsened OSA, which is a known complication of head and neck cancer treatment. When considering treatment options, upper airway stimulation is indeed a possible method in patients who meet the recommended guideline criteria.

Accumulation, distribution pattern and potential contamination of sulphur in vineyard soils of the Valdepeñas protected denomination origin.

Soil is the basis for almost all global agriculture and the medium in which most terrestrial biological activity occurs. Viticulture represents an important agricultural practice in the Castilla-La Mancha (CLM) community. In this region, there are several protected denominations of origin (PDO), the largest being Valdepeñas. This paper describes the accumulation pattern of sulphur (S) in the vineyard soils of this PDO. Samples were collected from 90 vineyard soil profiles. Sulphur content was determined using an X-ray Fluorescence spectrometer in the solid mode on a powdered aliquot of each sample. The results indicated that the total S in soils varied from 0.54 to 6.90 (g·kg-1) in surface soil (0-30 cm) and from 0.39 to 2.80 (g·kg-1) on the subsurface layer (30-80 cm). When comparing the mean values of surface horizons to the subsurface horizons, S content lowered as soil depth increased. Kurtosis exceeded 45 % in all cases, which indicates a wide variability of concentrations. These findings can be explained by the continuous fertiliser and fungicide applications (and therefore S) in these production systems. Using the geoaccumulation index (Igeo), most soils were included in Class 0 (Igeo <0) and were, thus, S uncontaminated; only a few points can be considered pollutants. The obtained results should contribute to extend the scarce existing database on S in Mediterranean regions like that herein studied.

Epidemiology and factors associated with Extra-pulmonary tuberculosis in a Low-prevalence area.

Background: Tuberculosis is a global public health problem. Extra-pulmonary tuberculosis accounts for an increasing proportion of cases worldwide, although information about epidemiological, clinical, or microbiological factors is lacking. Methods: We conducted a retrospective observational study of tuberculosis cases diagnosed between 2016 and 2021, classified into Pulmonary and Extra-pulmonary tuberculosis. Univariable and multivariable logistic regression models were used to investigate risk factors of Extra-pulmonary tuberculosis. Results: 20.9% of overall cases were classified as Extra-pulmonary tuberculosis, with a rising trend from 22.6% in 2016 to 27.9% in 2021. Lymphatic tuberculosis accounted for 50.6% of cases, followed by pleural tuberculosis (24.1%). 55.4% of cases belonged to foreign-born patients. Microbiological culture tested positive in 92.8% of Extra-pulmonary cases. Logistic regression analysis showed that women were more predisposed to develop Extra-pulmonary tuberculosis (aOR 2.46, 95% CI 1.45-4.20) as well as elderly patients (aged ≥ 65 years) (aOR 2.47, 95% CI 1.19-5.13) and persons with previous history of tuberculosis (4.99, 95% CI 1.40-17.82). Conclusions: Extra-pulmonary Tuberculosis have increased within our study period. A profound decline occurred in 2021 tuberculosis cases, probably due to COVID-19. Women, elderly population, and persons with previous history of tuberculosis are at higher risk of developing Extra-pulmonary tuberculosis in our setting.

Identification of antimicrobial resistance genes in intestinal content from Coyote (Canis latrans).

Antibiotic resistance has become a global public health concern in the last few years. Given the widespread rate of recurrence, increasing attention is being turned toward environmental pathways that potentially contribute to antibiotic resistance genes (ARGs) dissemination outside the clinical realm. In this study, a metagenome analysis of intestinal virus-like particle fraction (VLPs) from a wild coyote ( Canis latrans) revealed for the first time, multiple ARGs, such as B-lactamases and multidrug efflux pumps. Description of ARGs presence in natural environments is critical to understand the emergence of resistant strains.

Una aproximación actualizada hacia el tratamiento de la esclerosis múltiple / An updated approach to the treatment of multiple sclerosis

La presente es una revisión bibliográfica actualizada sobre el manejo de la Esclerosis Múltiple (EM), enfermedad neurológica progresiva de tipo desmielinizante más frecuente a nivel mundial. En Chile, su presentación remitente-recurrente (RRMS) es patología GES, por lo que se vuelve relevante para el médico general y estudiantes del área de la salud reconocer e identificar las terapias disponibles para el control de esta patología. Si bien la EM no es un cuadro frecuente, su sintomatología es alarmante e incapacitante, por lo que, con frecuencia, el primer acercamiento del paciente es a los servicios de urgencia, tornándose necesario contar con nociones básicas sobre el tratamiento y manejo. La presente revisión recopiló artículos publicados entre 2019 y 2023 de distintos motores de búsqueda con énfasis en el tratamiento farmacológico y no farmacológico de esta enfermedad. Además de describir el tratamiento convencional como la inmunomodulación, las terapias biológicas, el soporte con glucocorticoides y los fármacos remielinizantes, se abordan nuevas líneas de investigación prometedoras, como el rol inmunogénico de la microbiota intestinal, la capacidad epigenética de la dieta, estrategias de rehabilitación cognitiva y el potencial uso de cannabinoides para el manejo paliativo del dolor. Se concluye que un tratamiento oportuno con fármacos modificadores de la enfermedad, tanto de primera línea como de segunda, son imprescindibles para el manejo de la EM, sin embargo, la calidad de vida puede verse significativamente acrecentada por la incorporación de estrategias que se encuentran al alcance del médico general y que no requieren de derivación a nivel secundario.

This is an updated bibliographical review on the management of Multiple Sclerosis (MS), the most common progressive neurological disease of demyelinating disorders worldwide. In Chile, its relapsing-remitting presentation (RRMS) is a state-covered illness pathology, so it becomes relevant for the general practitioner and med students to recognize and identify therapies available for the control of this desease. Although MS is not a frequent condition, its symptoms are alarming and disabling, which is why, frequently, the first approach of the patient is to the emergency services, making it necessary to have basic knowledge about treatment and management. The present review compiled articles published between 2019 and 2023 from different search engines with an emphasis on the pharmacological and non-pharmacological treatment of the MS. In addition to describing conventional treatment such as immunomodulation, biological therapies, glucocorticoid support and remyelinating drugs, new promising lines of research are addressed, such as the immunogenic role of the intestinal microbiota, the epigenetic capacity of the diet, strategies on cognition rehabilitation and the potential use of cannabinoids for the palliative management of pain. It is concluded that the classic treatment with disease-modifying drugs, both first-line and second-line, are essential for the management of MS; however, quality of life can be significantly increased by incorporating strategies found at the reach of the general practitioner and do not require referral at a greater complexity center.

Mismatch repair system in colorectal cancer. Frequency, cancer phenotype, and follow-up.

INTRODUCTION AND AIMS: A frequent task in the study of colorectal carcinomas (CRC) is to identify tumors harboring deficient DNA mismatch repair systems (dMMR), which are associated with microsatellite instability. Given that there is scant information on those tumors in Mexican patients, our aim was to describe their frequency, clinical and pathologic characteristics, and results, which are necessary for future trials. MATERIALS AND METHODS: A consecutive series of CRC patients, treated and followed at a tertiary care center was performed. The clinical and pathologic variables and the risk of hereditary or familial cancer syndrome were retrieved. The original slides and hMLH1, hPMS2, hMSH2, hMSH6 immunohistochemistry were evaluated. Tumors with an absence of at least one protein were considered dMMR. Differences were contrasted, utilizing non-parametric tests. RESULTS: One hundred and forty-four patients were included, with a median age of 65 years. A total of 134/93% patients presented with sporadic CRC, 8/5.6% had a family history of CRC, and 2/1.4% met the diagnostic criteria for hereditary non-polyposis colon cancer, according to the Amsterdam and Bethesda criteria. dMMR tumors were found in 39 patients, distributed among the three groups. They were locally advanced (p<0.001), right-sided, had the mucinous phenotype, and harbored a Crohn's-like lymphoid reaction (all three features, p<0.04). Adjuvant or palliative chemotherapy was administered to 57 (39.6%), concomitant chemoradiotherapy to 24 (16.7%), but 63 (43.8%) patients received no additional treatment to surgery. Five-year follow-up was completed in 131 of the patients and the outcomes alive-with-disease or died-of-disease were more frequently observed in the proficient (pMMR) lesions. CONCLUSIONS: In the present pre-FOLFOX case series, outcomes were better in dMMR CRC than in proficient lesions.
