RESUMO

Surgical intervention is a key element in the management of patients diagnosed with mucormycosis. A retrospective cohort study was carried out, in which patients with a proven diagnosis of mucormycosis were evaluated over a period of 10 years, according to the MSGERC criteria. A descriptive analysis of the clinical characteristics, comorbidities, imaging, and microbiology studies, as well as medical and surgical treatment and the type of prosthesis was carried out. A total of 22 cases were identified, of which 54.5% (n = 12) of the population were men. Furthermore, 77.2% (n = 17) of the population had diabetes mellitus. The main antifungal treatment implemented was liposomal amphotericin B (77.2%, n = 17). The most affected structures in our patients were the paranasal sinuses (n = 18; 81%), followed by the maxilla and orbit (n = 15; 68%), nose (n = 12; 54%), central nervous system (n = 11; 50%), and skin and soft tissues (n = 2; <1%). Of the total population, 59.09% (n = 13) of patients underwent maxillofacial surgery, of which 61.53% (n = 8) required some type of prosthetic rehabilitation. Orbital exenteration and maxillectomy were the most frequent surgeries, accounting for 69.23% (n = 9), while skull base drainage was performed in four patients (30.76%). Of the total number of patients (n = 22), eight died (36.36%). Appropriate surgical management according to the affected structures, considering not only increasing the patient's survival, but also considering the aesthetic and functional consequences, will require subsequent rehabilitation.

RESUMO

BACKGROUND: Since 2011, over 30 tropical Atlantic nations have experienced substantial landings of holopelagic Sargassum spp. Its decomposition results in the production of hydrogen sulfide (H2S), which, in elevated concentrations, can pose a threat to human health. This study aims to enhance our understanding of the temporal and spatial variability in H2S emissions during the decomposition of Sargassum on beaches. The primary objective is to assess potential exposure risks for local populations, tourists, and cleanup workers. METHODS: H2S levels were monitored using a SENKO sensor (SGTP-H2S; limit of detection 0.1-100 ppm; resolution 0.1 ppm) at four distances from Sargassum accumulation points of (0, 10, 30, and 40 m) in Puerto Morelos, Mexico, during 2022 and 2023. RESULTS: Elevated concentrations of H2S were detected beneath the Sargassum piles, with 23.5% of readings exceeding 5 ppm and occasional spikes above 100 ppm. Above the piles, 87.3% of the measurements remained below 2 ppm, and the remainder fell between 2.1 and 5.2 ppm. At 10 m from the shoreline, 90% of measurements registered below 0.1 ppm, and the remaining 10% were below 2 ppm. Readings at 30 and 40 m consistently recorded levels below 0.1 ppm. H2S concentrations positively correlated with Sargassum pile height, the temperature beneath the piles, and wind speed. CONCLUSIONS: Our findings suggest no immediate and significant exposure risk for residents or tourists. However, Sargassum cleanup workers face a higher exposure risk, potentially encountering concentrations above 5 ppm for nearly one-fourth of the working time.

Objetivo: determinar factores que influyen en la no adherencia al tratamiento nutricional en pacientes hipertensos que acuden al Hospital Regional de Coronel Oviedo, 2021. Metodología: estudio descriptivo transversal. La población estuvo comprendida por pacientes registrados en el Programa de hipertensión arterial/Departamento cardiovascular del Hospital Regional de Coronel Oviedo. Se estudiaron los datos sociodemográficos, los factores de tratamiento nutricional y el grado de adherencia al tratamiento nutricional. Resultados: participaron del estudio 206 sujetos, el 53,4 % poseía 55 años o menos y el 81,1 % fue del sexo femenino. Se pudo hallar que solo el 3,8 % de los pacientes se adhieren al tratamiento. La no adherencia al factor conocimiento estuvo relacionado con el bajo nivel educativo (p=0,032), al factor equipo de salud con provenir del área rural y tener un bajo nivel educativo (p=0,006, p=0,002), al factor paciente con provenir del área rural (p=0.002), ser de bajo nivel educativo (p=0,008) y poseer obesidad grado II y III (p=0,036). La no adherencia global estuvo relacionada a estar casado (p=0.001) y realizar trabajos domésticos (p=0,009). Conclusiones: la adherencia al tratamiento es baja en la población de estudio.

Introduction: nutritional treatment is affected by the behavior of the subjects to generate adherence. This study was carried out to determine factors that influence non-adherence to nutritional treatment in hypertensive patients who attend the Coronel Oviedo Regional Hospital, 2021. Methodology: this was a cross-sectional descriptive observational study. The population was comprised of patients registered in the hypertension department of the Coronel Oviedo Regional Hospital. Sociodemographic data, nutritional treatment factors and the degree of adherence to nutritional treatment were studied. Results: 206 subjects participated in the study, 53.4 % were 55 years old or younger and 81.1 % were female. We found that only 3.8 % of patients adhere to treatment. Non-adherence due to the knowledge factor was related to low educational level (p=0.032), to the health team factor with coming from a rural area and having a low educational level (p=0.006, p=0.002), to the patient factor with coming from a rural area (p=0.002), to have a low educational level (p=0.008) and to have obesity grade II and III (p=0.036). Global non-adherence was related to being married (p=0.001) and doing housework (p=0.009). Conclusions: adherence to treatment is low in the study population.

RESUMO

Clavulanic acid (CLAV) is a non-antibiotic ß-lactam that has been used since the late 1970s as a ß-lactamase inhibitor in combination with amoxicillin, another ß-lactam with antibiotic activity. Its long-observed adverse reaction profile allows it to say that CLAV is a well-tolerated drug with mainly mild adverse reactions. Interestingly, in 2005, it was discovered that ß-lactams enhance the astrocytic expression of GLT-1, a glutamate transporter essential for maintaining synaptic glutamate homeostasis involved in several pathologies of the central nervous system (CNS). This finding, along with a favorable pharmacokinetic profile, prompted the appearance of several studies that intended to evaluate the effect of CLAV in preclinical disease models. Studies have revealed that CLAV can increase GLT-1 expression in the nucleus accumbens (NAcc), medial prefrontal cortex (PFC), and spinal cord of rodents, to affect glutamate and dopaminergic neurotransmission, and exert an anti-inflammatory effect by modulating the levels of the cytokines TNF-α and interleukin 10 (IL-10). CLAV has been tested with positive results in preclinical models of epilepsy, addiction, stroke, neuropathic and inflammatory pain, dementia, Parkinson's disease, and sexual and anxiety behavior. These properties make CLAV a potential therapeutic drug if repurposed. Therefore, this review aims to gather information on CLAV's effect on preclinical neurological disease models and to give some perspectives on its potential therapeutic use in some diseases of the CNS.

RESUMO

Introduction: International guidelines recommend hospital care for patients with severe Coronavirus disease (COVID-19), but fragile health care systems struggle to cope with high number of admissions, placing patients at risk of receiving substandard care. We describe an outpatient ambulatory surveillance and treatment strategy (OPAT) for health care workers (HCWs) with severe COVID-19 during low hospital bed availability periods in Mexico City. Methods: In this observational, descriptive, retrospective study, we included HCWs with severe disease for whom there were no hospital beds available at the time of evaluation. We provided daily assessments by infectious disease specialists, daily ambulatory steroid, oral thromboprophylaxis and domiciliary low-dose oxygen. We recorded the number of patients who recovered, were hospitalized or died on follow-up. Results: From 18 March 2020 to 16 July 2021, 1739 HCWs attended our service. A total of 540 were diagnosed with COVID-19. Seventy-four had severe COVID-19 and needed hospitalization. Immediate hospitalization was not possible in 56 patients who were sent to the OPAT and included in our study. Twenty-four patients subsequently required hospitalization and 32 recovered as outpatients. Conclusions: We describe a feasible and safe outpatient management strategy for HCWs with severe COVID-19 in a low-resource setting.

RESUMO

Objectives: Describe the use and findings of cardiopulmonary imaging-chest X-ray (cX-ray), echocardiography (cEcho), chest CT (cCT), lung ultrasound (LUS), and/or cardiac magnetic resonance imaging (cMRI)-in COVID-19 hospitalizations in Latin America (LATAM). Background: There is a lack of information on the images used and their findings during the SARS-CoV-2 pandemic in LATAM. Methods: Multicenter, prospective, observational study of COVID-19 inpatients, conducted from March to December 2020, from 12 high-complexity centers, in nine LATAM countries. Adults (>18 years) with at least one imaging modality performed, followed from admission until discharge and/or in-hospital death, were included. Results: We studied 1,435 hospitalized patients (64% males) with a median age of 58 years classified into three regions: Mexico (Mx), 262; Central America and Caribbean (CAC), 428; and South America (SAm), 745. More frequent comorbidities were overweight/obesity, hypertension, and diabetes. During hospitalization, 58% were admitted to the ICU. The in-hospital mortality was 28%, and it was highest in Mx (37%).The most frequent images performed were cCT (61%), mostly in Mx and SAm, and cX-ray (46%), significant in CAC. The cEcho was carried out in 18%, similarly among regions, and LUS was carried out in 7%, with a higher frequently in Mx. Abnormal findings on the cX-ray were peripheral or basal infiltrates, and in cCT abnormal findings were the ground glass infiltrates, more commonly in Mx. In LUS, interstitial syndrome was the most abnormal finding, predominantly in Mx and CAC.Renal failure was the most prevalent complication (20%), predominant in Mx and SAm. Heart failure developed in 13%, predominant in Mx and CAC. Lung thromboembolism was higher in Mx while myocardial infarction was in CAC.Logistic regression showed associations of abnormal imaging findings and their severity, with comorbidities, complications, and evolution. Conclusions: The use and findings of cardiopulmonary imaging in LATAM varied between regions and had a great impact on diagnosis and prognosis.

RESUMO

El absceso hepático piógeno es una patología que aún en nuestros días supone un reto médico, ya que su curso clínico suele ser grave, el diagnóstico frecuentemente tardío y la mortalidad elevada. En las últimas décadas hemos asistido a diversos avances, como la introducción de los antibióticos de amplio espectro y el desarrollo de técnicas de imagen e intervencionistas que han mejorado la eficacia diagnóstica y el pronóstico de esta patología. Pese a ello, la presencia de abscesos hepáticos piógenos múltiples no es una patología superada y presentamos un caso clínico que ilustre esta patología y justifique que ha de tenerse en cuenta en el arsenal diagnóstico para poder tratarlo precozmente y disminuir así su alta morbimortalidad.

Pyogenic liver abscess is a pathology that still poses a medical challenge today, since its clinical course is usually severe, diagnosis is often late, and mortality is high. In recent decades we have witnessed several advances, such as the introduction of broad-spectrum antibiotics and the development of imaging and interventional techniques that have improved the diagnostic efficacy and prognosis of this pathology. Despite this, the presence of multiple pyogenic liver abscesses is not a pathology that has been overcome and we present a clinical case that illustrates this pathology and justifies that it must be considered in the diagnostic arsenal in order to treat it early and thus reduce its high morbimortality.

RESUMO

The use of alternative medicine to treat pain has been increased, and the combination of several medicinal plants for its relief is a common practice in traditional medicine. The present study is aimed at determining whether a combination of Syzygium aromaticum (S. aromaticum) and Rosmarinus officinalis L. (R. officinalis) potentiates their antinociceptive and anti-inflammatory effects. These effects were explored using the formalin and carrageenan assays in rats, respectively. Animals received local pretreatment with S. aromaticum oil or R. officinalis ethanolic extract (0.1-100 µg/paw) alone or combined in a 1 : 1 rate. Concentration-response curves were built to compare pharmacological responses after an individual administration of S. aromaticum, R. officinalis, or their combination. The pharmacological interaction was investigated by an isobolographic study using the EC50 of each component in a fixed 1 : 1 ratio. S. aromaticum and R. officinalis administered alone showed significant and concentration-dependent antinociceptive and anti-inflammatory effects, but R. officinalis was more potent than S. aromaticum in both the antinociceptive and anti-inflammatory effects (EC50 = 7.96 ± 0.6 µg/paw vs. EC50 = 41.6 ± 1.7 µg/paw; EC50 = 1.97 ± 0.3 µg/paw vs. EC50 = 26.9 ± 2.5 µg/paw, respectively). The isobolographic analysis of the combination of these species in a 1 : 1 ratio showed a synergistic interaction between S. aromaticum and R. officinalis since Z mix (experimental value) was lower than Z add (theoretical value) for both the antinociceptive effect (Z mix = 0.45 ± 0.1 < Z add = 24.8 ± 1.3) and the anti-inflammatory effect (Z mix = 5.2 ± 0.6 < Z add = 14.4 ± 2.2), suggesting a potentiation for both pharmacological effects. These results prove evidence of the efficacy of mixture herb-herb used in folk medicine for pain therapy. It also emphasizes the requirement of pharmacological studies to explore the efficacy and safety of herb interactions.

RESUMO

ABSTRACT Liver transplantation is the major treatment for end-stage liver disease. Postoperative care is a great challenge to reduce morbidity and mortality in patients. In this sense, management in the liver ICU allows hemodynamic management, coagulation monitoring, renal support, electrolyte disturbances, respiratory support and early weaning from mechanical ventilation and evaluation of the liver graft. Objective: The present study shows the results of the management of liver transplant patients in 20 years of experience in a transplant center in a low- to middle-income country. Materials and methods: The medical records of 273 adult patients in the ICU in the immediate postoperative liver transplant were reviewed, from March 20, 2000 to November 30, 2020, including the effect of the pandemic caused by COVID-19. Liver-kidney, retransplanted, SPLIT, and domino transplant patients were excluded. Results: The most frequent etiology for LTx was NASH (35%), the mean age was 49 years, MELD Score ranged 15 - 20 (47.5%), 21 - 30 (46%) > 30 (6.2%). ICU pre transplant stay 7%, average ICU stay: 7.8 days. APACHE average admission: 14.9 points. Weaning extubation of 91.8% patients in ICU and Fast Track in 8.2%. The most frequent respiratory complication was atelectasis 56.3%, pneumonia (31.3%); AKI 1 (60.9%), and 11.1% with hemodyalisis support (AKI3). Immunosuppression: Tacrolimus (8.9%). Post-operative ICU mortality was 6.2%. Conclusions: The management of liver transplantation in the ICU is essential to achieve optimal results in patients who present advanced liver disease and require advanced life support in the immediate postoperative period and thus optimize graft survival.
