Air quality of health facilities in Spain.

The present study examines indoor air pollution in health facilities, focusing on compounds from various sources, such as industrial products, healthcare activities and building materials. It assesses chemical and microbiological concentrations in two public hospitals, two public healthcare centres, and one public health laboratory in Spain. Measurements included indoor air quality, microbiological contaminants, ambient parameters and non-target analysis across ten different locations. Outdoor air quality was also assessed in the surroundings of the hospitals. The results showed that around 350 substances were tentatively identified at a high confidence level, with over 50 % of compounds classified as of high toxicological risk. Three indoor and 26 outdoor compounds were fully confirmed with standards. These confirmed substances were linked to medical, industrial and agricultural activities. Indoor Air Quality (IAQ) results revealed that CO, CO2, formaldehyde (HCHO), O3 and total volatile organic compounds (TVOCs) showed average values above the recommended guideline levels in at least one of the evaluated locations. Moreover, maximum concentrations detected for CO, HCHO, O3 and TVOCs in hospitals surpassed those previously reported in the literature. SARS-CoV-2 was detected in three air environments, corresponding to COVID-19 patient areas. Fungi and bacteria concentrations were acceptable in all assessed locations, identifying different fungi genera, such as Penicillium, Cladosporium, Aspergillus, Alternaria and Botrytis.

Postural orthostatic tachycardia syndrome and other related dysautonomic disorders after SARS-CoV-2 infection and after COVID-19 messenger RNA vaccination.

The COVID-19 pandemic has caused a challenge for our society due to the post-acute sequelae of the disease. Persistent symptoms and long-term multiorgan complications, known as post-acute COVID-19 syndrome, can occur beyond 4 weeks from the onset of the COVID-19 infection. Postural orthostatic tachycardia syndrome (POTS) is considered a variety of dysautonomia, which is characterized by chronic symptoms that occur with standing and a sustained increase in heart rate, without orthostatic hypotension. POTS can lead to debilitating symptoms, significant disability, and impaired quality of life. In this narrative review, the etiopathogenic basis, epidemiology, clinical manifestations, diagnosis, treatment, prognosis, and socioeconomic impact of POTS, as well as other related dysautonomic disorders, after COVID-19 infection and SARS-CoV-2 postvaccination, were discussed. After a search conducted in March 2023, a total of 89 relevant articles were selected from the PubMed, Google Scholar, and Web of Science databases. The review highlights the importance of recognizing and managing POTS after COVID-19 infection and vaccination, and the approach to autonomic disorders should be known by all specialists in different medical areas. The diagnosis of POTS requires a comprehensive clinical assessment, including a detailed medical history, physical examination, orthostatic vital signs, and autonomic function tests. The treatment of POTS after COVID-19 infection or vaccination is mainly focused on lifestyle modifications, such as increased fluid and salt intake, exercise, and graduated compression stockings. Pharmacotherapy, such as beta-blockers, fludrocortisone, midodrine, and ivabradine, may also be used in selected cases. Further research is needed to understand the underlying mechanisms, risk factors, and optimal treatment strategies for this complication.

Fusariosis in cancer patients: 13 case series report and literature review / Fusariosis en pacientes con cáncer: serie de 13 casos y revisión de la literatura

The fusariosis is an opportunistic mycosis caused by Fusarium spp. Its clinical presentation depends on the immunological status of the host, especially in patients with hematooncological diseases, whose manifestations vary from localized to invasive fungal infections. Skin or blood culture helps to guide combined antifungal treatment with amphotericin B and voriconazole. Here, we present 13 cases in a period of eleven years of patients with cancer who developed disseminated fusariosis and their outcomes, together with a review of the related literature. In this series of cases, mortality was 61.5 % (8/13), despite the use of the antifungal. Out of the 13 cases, 11 had hematological neoplasia and 2 solid neoplasia. The most determinant risk factor was profound neutropenia. Skin involvement and positive blood cultures in most cases allowed combined treatment prescription. Persistent febrile neutropenia associated with skin lesions, onychomycosis, nodules, or lung masses lead to suspicion of Fusarium spp. fungal invasive infection. The aim of this series of cases is to remind healthcare professionals that oncological patients with deep and persistent febrile neutropenia can develop fusariosis.

La fusariosis es una micosis oportunista producida por Fusarium spp. Su presentación clínica depende del estado inmunológico del huésped, especialmente, el de aquellos con enfermedades hematooncológicas, cuyas manifestaciones varían desde formas localizadas hasta infección fúngica invasora. El cultivo de piel o de sangre permite orientar el tratamiento antifúngico combinado con anfotericina B y voriconazol. Se presentan 13 casos de pacientes con cáncer en un periodo de once años que desarrollaron fusariosis diseminada; asimismo, se hizo con una revisión extensa de la literatura. En esta serie de casos, la mortalidad fue del 61,5 % (8/13), a pesar del uso del antifúngico. De los 13 pacientes, 11 tenían neoplasia hematológica y 2 neoplasia sólida. El factor de riesgo más importante fue la neutropenia profunda. El compromiso de la piel y los hemocultivos positivos facilitaron la prescripción del tratamiento combinado en la mayoría de los casos. La neutropenia febril persistente asociada a lesiones cutáneas, la onicomicosis, los nódulos o las masas pulmonares permitieron sospechar una infección fúngica invasora por Fusarium spp. El objetivo de la presentación de esta serie de casos es recordar el diagnóstico de fusariosis a la comunidad médica en contacto con pacientes oncológicos, con neutropenia febril profunda y persistentes.

Associated factors for mortality in a COVID-19 colombian cohort: is the third wave relevant when Mu variant was predominant epidemiologically?

OBJECTIVES: To evaluate the association between Colombia's third wave when the Mu variant was predominant epidemiologically (until 75%) in Colombia and COVID-19 all-cause in-hospital mortality. METHODS: In this retrospective cohort, we included hospitalized patients ≥18 years with SARS-CoV-2 infection between March 2020 to September 2021 in ten hospitals from three cities in Colombia. Description analysis, survival, and multivariate Cox regression analyses were performed to evaluate the association between the third epidemic wave and in-hospital mortality. RESULTS: A total of 25,371 patients were included. The age-stratified time-to-mortality curves showed differences according to epidemic waves in patients ≥75 years (log-rank test p = 0.012). In the multivariate Cox analysis, the third wave was not associated with increased mortality relative to the first wave (aHR 0.95; 95%CI 0.84-1.08), but there was an interaction between age ≥75 years and the third wave finding a lower HR for mortality (aHR 0.56, 95%CI 0.36-0.86). CONCLUSIONS: We did not find an increase in in-hospital mortality during the third epidemic wave in which the Mu variant was predominant in Colombia. The reduced hazard in mortality in patients ≥75 years hospitalized in the third wave could be explained by the high coverage of SARS-CoV-2 vaccination in this population and patients with underlying conditions.

Fungemia in Hospitalized Adult Patients with Hematological Malignancies: Epidemiology and Risk Factors.

Fungemia in hematologic malignancies (HM) has high mortality. This is a retrospective cohort of adult patients with HM and fungemia between 2012 and 2019 in institutions of Bogotá, Colombia. The epidemiological, clinical, and microbiological characteristics are described, and risk factors related to mortality are analyzed. One hundred five patients with a mean age of 48 years (SD 19.0) were identified, 45% with acute leukemia and 37% with lymphomas. In 42%, the HM was relapsed/refractory, 82% ECOG > 3, and 35% received antifungal prophylaxis; 57% were in neutropenia, with an average duration of 21.8 days. In 86 (82%) patients, Candida spp. was identified, and other yeasts in 18%. The most frequent of the isolates were non-albicans Candida (61%), C. tropicalis (28%), C. parapsilosis (17%), and C. krusei (12%). The overall 30-day mortality was 50%. The survival probability at day 30 in patients with leukemia vs. lymphoma/multiple myeloma (MM0 group was 59% (95% CI 46-76) and 41% (95% CI 29-58), p = 0.03, respectively. Patients with lymphoma or MM (HR 1.72; 95% CI 0.58-2.03) and ICU admission (HR 3.08; 95% CI 1.12-3.74) were associated with mortality. In conclusion, in patients with HM, non-albicans Candida species are the most frequent, and high mortality was identified; moreover, lymphoma or MM and ICU admission were predictors of mortality.

Identification of human leukocyte antigen in precancerous and cancerous cervical lesions from Ecuadorian women.

Cervical cancer is the fourth most common type of cancer in women. Worldwide, it is a public health problem with around 604,127 women diagnosed per year and 341,831 deaths. Cervical cancer and persistent high-risk human papillomavirus (HPV) infection are highly associated. However, other factors are also involved, such as viral load, HPV variants, sexual behavior, and genetic factors. The host immune response against HPV has been widely studied and it has shown associations with development of cervical cancer. The human leukocyte antigen (HLA) genes are related to the persistence of HPV infection and progression to cervical cancer because of their role in controlling T-cell mediated immune response to clear the infection. In Ecuador, there is scarce information about HLA and HPV infection with high-risk genotypes in the population. This study aimed to identify host-specific HLA alleles in women with cervical intraepithelial neoplasia (CIN) II and III, and cancer infected with HPV-16, 58, and 52. In this study, we included 51 samples previously identified as positive for HPV-16, 58, and 52 from 12 Ecuadorian provinces. As a result, we found that HLA-A*02, HLA-B*35, HLA-C*04, HLA-DRB1*04, and HLA-DQB1*03 alleles were the most frequent, these alleles have been associated with cervical cancer in previous studies; nevertheless, we did not find a statistically significant association between HLA alleles, HPV genotype, and histopathological lesion. This is a baseline study to uncover possible relationships between HLA and HPV to elucidate why this virus can develop a persistent infection in some women leading to the development of cervical cancer.

Clusterin levels in undernourished SH-SY5Y cells.

Food-related disorders are increasingly common in developed societies, and the psychological component of these disorders has been gaining increasing attention. Both overnourishment with high-fat diets and perinatal undernourishment in mice have been linked to a higher motivation toward food, resulting in an alteration in food intake. Clusterin (CLU), a multifaced protein, is overexpressed in the nucleus accumbens (NAc) of over-fed rats, as well as in those that suffered chronic undernutrition. Moreover, an increase of this protein was observed in the plasma of obese patients with food addiction, suggesting the implication of CLU in this eating disorder. To characterize CLU's cellular mechanisms, in vitro experiments of undernutrition were performed using dopaminergic SH-SY5Y cells. To mimic in vivo dietary conditions, cells were treated with different fetal bovine serum (FBS) concentrations, resulting in control (C group) diet (10% FBS), undernourishment (U group) diet (0.5% FBS), and undernourishment diet followed by restoration of control diet (UC group) (0.5 + 10% FBS). Undernourishment compromised cell viability and proliferation, and concomitantly increased CLU secretion as well as the cytosolic pool of the protein, while decreasing the mitochondrial level. The restoration of normal conditions tended to recover cell physiology, and the normal levels and distribution of CLU. This research study is a step forward toward the characterization of clusterin as a potential marker for food addiction and nutritional status.

[Inappropriate antifungal prescription and the need for antifungal stewardship programs]. / Prescripción inapropiada de antifúngicos y la necesidad de programas para su uso racional.

Invasive fungal disease (IFD) is a condition affecting immunosuppressed and critically ill patients. Recently there has been an increase in the amount of patients at risk for IFD, which implies an increase in the prescription of antifungal agents as prophylactic, pre-emptive or empiric therapy. Some studies evaluating appropriateness of antifungal prescription have shown that inappropriate formulations reach 72%, exposing patients to side effects, pharmacological interactions and rising costs. Some groups have recommended many interventions to control and make a rational use of antimicrobials, into strategies known as "antimicrobial stewardship", these interventions are useful also for antifungal agents and it has been named "antifungal stewardship". Here we present a narrative review of the scientific literature showing published articles about appropriate use of antifungal agents and the experience of some centers after implementing antifungal stewardship programs.

Prescripción inapropiada de antifúngicos y la necesidad de programas para su uso racional / Inappropriate antifungal prescription and the need for antifungal stewardship programs

Resumen La enfermedad fúngica invasora (EFI) es una entidad que afecta pacientes inmunocomprometidos y críticamente enfermos. En los últimos años, el número de pacientes con riesgo de presentarla viene en aumento, con el consecuente incremento de la formulación de antifúngicos de manera profiláctica, anticipada o empírica. Algunos estudios que evaluaron el uso adecuado de antifúngicos han mostrado que hasta 72% de las formulaciones pueden ser inapropiadas, exponiendo a los pacientes al riesgo de efectos adversos e interacciones medicamentosas, con mayores costos de la atención. Se han recomendado diferentes intervenciones para el control y el uso racional de antimicrobianos, conocidas como "antimicrobial stewardship", las que se pueden aplicar al uso de antifúngicos denominándose "antifungal stewardship"". Se presenta una revisión de la literatura médica sobre el uso apropiado de antifúngicos y el impacto de la implementación de programas de optimización del uso de estos medicamentos en algunos centros.

Persistence of secondary mitral regurgitation and response to cardiac resynchronization therapy.

AIMS: Cardiac resynchronization therapy (CRT) improves survival and quality of life in advanced heart failure (HF). Although mitral regurgitation (MR) reduction has been reported, its presence has been associated with non-response to CRT. This study was undertaken to assess the potential role of significant mitral regurgitation (SMR) persistence after CRT on clinical outcome, major arrhythmic events, and echocardiographic response in the mid-long term. METHODS AND RESULTS: Seventy-six patients (28.9% women, 63 +/- 11 years) with dilated cardiomyopathy in advanced HF were included. SMR, defined as regurgitant orifice area > or =0.20 cm(2), was assessed at baseline and its evolution 6 months after CRT. Clinical outcome (cardiovascular death/HF readmission), major arrhythmic events, and echocardiographic response (reverse remodelling) were recorded on follow-up. Thirty-two patients (42.1%) presented baseline SMR, becoming non-significant in 11 of the 32 patients (34.3%) 6 months after CRT. Its persistence was associated with higher rates of clinical events (46.4 vs. 18.7%, P = 0.011), arrhythmic events (35.7 vs. 14.5%, P = 0.034), and less reverse remodelling (28.5 vs. 83.3%, P < 0.001). CONCLUSION: CRT can reduce moderate or severe baseline MR to non-significant in one-third of patients. However, its persistence was associated with worse clinical evolution, greater incidence of arrhythmic events, and less reverse remodelling.

Combined resynchronization therapy and automatic defibrillator in advanced non-ischaemic heart failure: the importance of QRS width.

AIMS: The combined use of an automatic defibrillator in resynchronization therapy for primary prevention in patients with idiopathic dilated cardiomyopathy is controversial. METHODS AND RESULTS: We assessed a series of 46 patients (61 +/- 10 years, 64% male) with idiopathic dilated cardiomyopathy undergoing resynchronization therapy combined with a defibrillator in primary prevention and the potential relationship between baseline characteristics and the onset of ventricular arrhythmic events. Of the 46 patients included, eight (17%) presented episodes of ventricular tachycardia/fibrillation during follow-up (19 +/- 12 months). There were no baseline differences among these patients, except the proportion of males (57.9 vs. 100%, P = 0.02) and QRS width (162 +/- 24 vs. 189 +/- 26 ms, P = 0.008), which was the only independent predictor of arrhythmic events (OR 1.42, 95% CI 1.12-1.68; P = 0.03). CONCLUSION: In patients with idiopathic dilated cardiomyopathy undergoing resynchronization therapy combined with a defibrillator, baseline QRS is an independent predictor of arrhythmic events.

Valor pronóstico del péptido natriurético cerebral en el síndrome coronario agudo sin elevación del segmento ST / Prognostic value of B-type natriuretic peptide in unstable angina and non-ST-elevation myocardial infarction

Fundamentos y objetivo: El péptido natriurético cerebral (BNP) ha emergido como marcador pronóstico en síndromes coronarios agudos (SCA), lo que se sustenta fundamentalmente en estudios sobre poblaciones seleccionadas. El objetivo del presente estudio prospectivo de cohortes fue evaluar el valor pronóstico del BNP en pacientes no seleccionados con SCA sin elevación del segmento ST (SCASEST). Pacientes y método: Se estudió de forma prospectiva a los pacientes ingresados por SCASEST durante 2007; se consideraron elevados valores del BNP superiores a 80pg/ml y se recogió la aparición de eventos cardiovasculares mayores durante el seguimiento. Resultados: Se incluyeron 100 pacientes (BNP elevado en el 48%), registrándose 21 eventos tras un año de seguimiento: 12 pacientes reingresaron por SCA, 7 pacientes por insuficiencia cardíaca (IC) y 2 pacientes fallecieron de forma súbita. El único predictor independiente de IC y de mortalidad en el seguimiento fue la presencia de valores elevados de BNP durante el ingreso, sin relacionarse éste con la aparición de nuevos episodios isquémicos. Conclusiones: En pacientes con SCASEST no seleccionados, los valores elevados de BNP resultaron predictores de IC y de mortalidad en el seguimiento (AU)

Background and objective: the B-type natriuretic peptide (BNP) has recently emerged as a prognostic marker in acute coronary syndromes (ACS). This role is based on results from randomized trials and other high selected population studies. The aim of this study was to determine the prognostic value of BNP in unselected patients with non-ST-elevated-ACS. Patients and method: BNP plasma concentrations were measured in 100 consecutive patients admitted in 2007 with non-ST-elevated-ACS, taking as cut-off value 80pg/ml (high BNP levels on 48% of patients).Results: After one year-of follow-up, 21 major adverse cardiovascular events occurred: 12 ACS, 7 hospitalizations for heart failure and 2 sudden cardiac deaths. No relationship was found between BNP levels and events on follow-up. BNP >80pg/ml was the only independent predictor of heart failure and death. No relationship was found between high levels of BNP and coronary events during the follow-up. Conclusions: BNP was an independent predictor of heart failure and mortality in unselected patients with non-ST-elevated-ACS (AU)

Male perineogenital anatomy and clinical applications in genital reconstructions and male-to-female sex reassignment surgery.

To determine the possibility of providing alternative surgical techniques for male genital reconstruction and for male-to-female sex reassignment surgery, the authors undertook an anatomic investigation of the perineogenital region in male cadavers. Anatomic dissection was performed on 14 male adult human cadavers (fresh and formalin-preserved) studying the main afferent vessels to the anterior perineal region and their mean internal diameters: deep external pudendal artery (0.60 mm), superficial perineal artery (0.50 mm), and funicular artery (0.37 mm). We established their exact topography, together with vascular anatomic variations, main vascular anastomosis circuits (base of the penis, scrotal septum, and perineal fat and lateral spermatic-scrotal fascia), angiosomes, anatomy of the rectovesical septum cavity, and their "critical" key points of dissection. The authors discuss the clinical possibility of elevation of a "tree" of previously described paragenital-genital flaps including mainly those based on the terminal branches of the internal pudendal vascular system, the erectile tissue pedicled flaps, and finally, flaps of the external pudendal system. The authors indicate the concrete vascularization system for each flap.
