Anticuerpos contra el SARS-CoV-2 tras la dosis de vacuna de recuerdo. Identificación de subgrupos con respuesta insuficiente / SARS-CoV-2 antibodies after booster vaccination. Identification of subgroups with poor response

Objetivo Identificar dentro del grupo de pacientes de alto riesgo a aquellos que presentan más posibilidad de presentar inmunidad postvacunal insuficiente. Método Determinación de títulos de IgG frente a SARS-CoV-2 después de la dosis de recuerdo. Se clasificó la respuesta vacunal como negativa (títulos IgG <34 BAU/ml), indeterminada (títulos 34 - 259 BAU/ml) o positiva (≥260 BAU/ml). Resultados Se incluyeron 765 pacientes (31,25% de los vacunados): 54 (7,1%) en tratamiento con fármacos biológicos, 90 (11,8%) con enfermedad hematológica, 299 (39,1%) con patología oncológica, 304 (39,7%) con trasplante de órgano sólido y 18 (2,4%) con inmunosupresión por otros motivos. Un total de 74 pacientes (9,7%) tuvieron una serología negativa y 45 (5,9%) obtuvieron títulos indeterminados. Por grupo diagnóstico, los pacientes con mayor porcentaje de serología negativa o indeterminada fueron pacientes bajo tratamiento con fármacos biológicos (55,6%, fundamentalmente a expensas de antiCD20), hematológicos (35,4%) y los trasplantados (17,8%, principalmente pulmón y riñón). Los pacientes oncológicos y otros pacientes inmunosuprimidos tuvieron buena respuesta vacunal. Conclusión Los pacientes tratados con fármacos antiCD20, los hematológicos y los trasplantados (fundamentalmente de pulmón y riñón) presentaron mayor riesgo de no desarrollar inmunidad postvacunal. Es fundamental su identificación de cara a individualizar y mejorar su manejo (AU)

Objective To determine which patients within the high-risk group are most likely to have insufficient post-vaccination immunity. Methods Determination of IgG titers against SARS-CoV-2 after the booster dose. Vaccine response was categorized as negative (IgG titers <34 BAU/ml), indeterminate (titers 34 - 259 BAU/ml) or positive (≥ 260 BAU/ml). Results 765 patients were included (31.25% of those vaccinated). 54 (7.1%) on treatment with biologics, 90 (11.8%) with hematologic disease, 299 (39.1%) with oncologic pathology, 304 (39.7%) with solid organ transplant and 18 (2.4%) with immunosuppression for other reasons. 74 patients (9.7%) had negative serology and 45 (5.9%) had indeterminate titers. By diagnostic group, the patients with the highest proportion of negative or indeterminate serology were patients with biologic treatment (55.6%, mainly at expense of antiCD20), hematologic (35.4%) and transplant patients (17.8%, mainly lung and kidney). Oncology and other immunosuppressed patients had a favorable response to vaccination. Conclusion Patients treated with antiCD20 drugs, hematologic patients and transplanted patients (mainly lung and kidney) have a higher risk of not achieving post-vaccination immunity. It is essential to identify them in order to individualize and optimize their management (AU)

[Health-related quality of life in patients recovered from COVID-19]. / Calidad de vida relacionada con la salud en pacientes recuperados de COVID-19.

INTRODUCTION: The presence of symptoms after acute SARS-CoV-2 infection is frequent and has an impact on patients' quality of life. The aim of this study is to assess the health-related quality of life of COVID-19 survivors and to ascertain which factors are related to worse results. METHODS: An observational, cross-sectional study has been performed, using, a telephone survey that was administered to all patients with COVID-19 from the first pandemic wave in our healthcare area 10months after the acute infection. Patients with dementia and nursing home residents were excluded. Health-related quality of life was assessed using the EQ-5D instrument and its índices EQ-VAS and EQ-Health Index. RESULTS: 443 answers were collected. Mean age was 54±16 and 38.4% of patients were male. The most affected domain was anxiety/depression (23.9% of patients) and mobility (16.5%). Mean global EQ-VAS score was 75.8±18.7, and mean EQ-Health Index was 0.884±0.174. Both VAS and Health Index scores were lower in females, patients older than 65 years, patients with comorbidities, and those who needed hospital admission during the acute infection. VAS scores in our sample were lower than in the general Spanish population, but similar to the scores in our region prior to the pandemic. Female sex, hospital admission, and a lower educational status were independently associated to lower EQ-Health Index scoring. CONCLUSION: While health self-perception is affected after COVID-19, this might not be directly related to the infection. There exist profiles of patients more prone to a worse quality of life in which interventions may be considered.

Telemedicina con telemonitorización en el seguimiento de pacientes con COVID-19 / Tracing of COVID-19 patients by telemedicine with telemonitoring

OBJETIVO: Evaluar si la telemedicina con telemonitorización es una herramienta clínicamente útil y segura para el seguimiento de pacientes con COVID-19. MÉTODOS: Estudio observacional prospectivo de los pacientes con diagnóstico de COVID-19 por PCR positiva y considerados de alto riesgo que se siguieron con telemedicina y telemonitorización en el Área Sanitaria de Lugo entre el 17 de marzo y el 17 de abril de 2020. Se incluyeron dos grupos de pacientes: seguimiento ambulatorio desde el inicio y tras el alta hospitalaria. Cada paciente remitió un cuestionario clínico al día con su temperatura y saturación de oxígeno 3 veces al día. El seguimiento fue proactivo contactando con todos los pacientes al menos una vez al día. RESULTADOS: Se incluyeron 313 pacientes (52,4% mujeres) con edad media 60,9 (DS 15,9) años. Otros 2 pacientes rehusaron entrar en el programa. Desde el inicio se siguieron ambulatoriamente 224 pacientes y 89 tras su alta hospitalaria. Entre los primeros, 38 (16,90%) se remitieron a Urgencias en 43 ocasiones con 18 (8,03%) ingresos y 2 fallecidos. En los domicilios no hubo fallecimientos ni urgencias vitales. Incluyendo a los pacientes tras hospitalización, el seguimiento se realizó en 304 casos. Un paciente reingresó (0,32%) y otro abandonó (0,32%). El tiempo medio de seguimiento fue 11,64 (SD 3,58) días y en los 30 días del estudio 224 (73,68%) pacientes fueron dados de alta. CONCLUSIONES: Nuestros datos sugieren que la telemedicina con telemonitorización domiciliaria, utilizada de forma proactiva, permite un seguimiento clínicamente útil y seguro en pacientes con COVID-19 de alto riesgo

AIM: To asses if telemedicine with telemonitoring is a clinically useful and secure tool in the tracking of patients with COVID-19. METHODS: A prospective observational study of patients with COVID-19 diagnosis by positive PCR considered high-risk tracked with telemedicine and telemonitoring was conducted in the sanitary area of Lugo between March 17th and April 17th, 2020. Two groups of patients were included: Outpatient Tracing from the beginning and after discharge. Every patient sent a daily clinical questionnaire with temperature and oxygen saturation 3 times a day. Proactive monitoring was done by getting in touch with every patient at least once a day. RESULTS: 313 patients (52.4% female) with a total average age of 60.9 (DS 15.9) years were included. Additionally, 2 patients refused to join the program. Since the beginning, 224 were traced outpatient and 89 after being discharged. Among the first category, 38 (16.90%) were referred to Emergency department on 43 occasions; 18 were hospitalized (8.03%), and 2 deceased. Neither deaths nor a matter of vital emergency occurred at home. When including patients after admissions monitoring was done in 304 cases. One patient re-entered (0.32%) to the hospital, and another one left the program (0.32%). The average time of monitoring was 11.64 (SD 3.58) days, and 224 (73.68%) patients were discharged during the 30 days of study.

Effects of caffeine supplementation on physical performance and mood dimensions in elite and trained-recreational athletes.

BACKGROUND: Caffeine supplementation (CAFF) has an established ergogenic effect on physical performance and the psychological response to exercise. However, few studies have compared the response to CAFF intake among athletes of different competition level. This study compares the acute effects of CAFF on anaerobic performance, mood and perceived effort in elite and moderately-trained recreational athletes. METHODS: Participants for this randomized, controlled, crossover study were 8 elite athletes (in the senior boxing national team) and 10 trained-recreational athletes. Under two experimental conditions, CAFF supplementation (6 mg/kg) or placebo (PLAC), the athletes completed a Wingate test. Subjective exertion during the test was recorded as the rating of perceived exertion (RPE) both at the general level (RPEgeneral) and at the levels muscular (RPEmuscular) and cardiorespiratory (RPEcardio). Before the Wingate test, participants completed the questionnaires Profiles of Moods States (POMS) and Subjective Vitality Scale (SVS). RESULTS: In response to CAFF intake, improvements were noted in Wpeak (11.22 ± 0.65 vs 10.70 ± 0.84; p = 0.003; [Formula: see text] =0.44), Wavg (8.75 ± 0.55 vs 8.41 0.46; p = 0.001; [Formula: see text] =0.53) and time taken to reach Wpeak (7.56 ± 1.58 vs 9.11 ± 1.53; p <  0.001; [Formula: see text] =0.57) both in the elite and trained-recreational athletes. However, only the elite athletes showed significant increases in tension (+ 325%), vigor (+ 31%) and SVS (+ 28%) scores after the intake of CAFF compared to levels recorded under the condition PLAC (p <  0.05). Similarly, levels of vigor after consuming CAFF were significantly higher in the elite than the trained-recreational athletes (+ 5.8%). CONCLUSIONS: CAFF supplementation improved anaerobic performance in both the elite and recreational athletes. However, the ergogenic effect of CAFF on several mood dimensions and subjective vitality was greater in the elite athletes.

Serum IL-15 and IL-15Rα levels are decreased in lean and obese physically active humans.

Circulating IL-15 presence is required to stimulate anti-adipogenic effects of the IL-15/IL-15Rα axis in adipose tissue. Although exercise increases blood IL-15 expression post-exercise, it remains inconclusive whether physical activity can alter the baseline concentrations of this cytokine. The aim of this study was to determine whether physical activity regulates circulating IL-15 and IL-15Rα in lean and obese individuals. Two hundred and seventy-six participants were divided into five groups according to physical activity (PA), body mass and type 2 diabetes mellitus (T2DM) diagnosis: (a) lean PA (N = 25); (b) lean non-PA (N = 28); (c) obese PA (N = 64); (d) obese non-PA (N = 79); and (e) obese non-PA with T2DM (N = 80). Serum IL-15 and IL-15Rα, blood glucose/lipid profile and body composition were measured. Serum IL-15 and IL-15Rα decreased in PA participants compared to non-PA (P < .05), while IL-15 and IL-15Rα increased in obese with T2DM compared to obese without T2DM (P < .05). No differences were observed between lean non-PA and obese PA. Serum IL-15Rα was associated with fasting glucose (R2 = .063), insulin (R2 = .082), HbA1c (R2 = .108), and HOMA (R2 = .057) in obese participants. Circulating IL-15 and IL-15Rα are reduced in lean and obese participants who perform physical activity regularly (≥180 min/week), suggesting a regulative role of physical activity on the circulating concentrations of IL-15 and IL-15Rα at baseline. Moreover, the relationship observed between IL-15Rα and glucose profile may indicate a role of the alpha receptor in glucose metabolism.

Skeletal muscle IL-15/IL-15Rα and myofibrillar protein synthesis after resistance exercise.

In vitro and in vivo studies described the myokine IL-15 and its receptor IL-15Rα as anabolic/anti-atrophy agents, however, the protein expression of IL-15Rα has not been measured in human skeletal muscle and data regarding IL-15 expression remain inconclusive. The purpose of the study was to determine serum and skeletal muscle IL-15 and IL-15Rα responses to resistance exercise session and to analyze their association with myofibrillar protein synthesis (MPS). Fourteen participants performed a bilateral leg resistance exercise composed of four sets of leg press and four sets of knee extension at 75% 1RM to task failure. Muscle biopsies were obtained at rest, 0, 4 and 24 hours post-exercise and blood samples at rest, mid-exercise, 0, 0.3, 1, 2, 4 and 24 hours post-exercise. Serum IL-15 was increased by ~5.3-fold immediately post-exercise, while serum IL-15Rα decreased ~75% over 1 hour post-exercise (P<.001). Skeletal muscle IL-15Rα mRNA and protein expression were increased at 4 hours post-exercise by ~2-fold (P<.001) and ~1.3-fold above rest (P=.020), respectively. At 24 hours post-exercise, IL-15 (P=.003) and IL-15Rα mRNAs increased by ~2-fold (P=.002). Myofibrillar fractional synthetic rate between 0-4 hours was associated with IL-15Rα mRNA at rest (r=.662, P=.019), 4 hours (r=.612, P=.029), and 24 hours post-exercise (r=.627, P=.029). Finally, the muscle IL-15Rα protein up-regulation was related to Leg press 1RM (r=.688, P=.003) and total weight lifted (r=.628, P=.009). In conclusion, IL-15/IL-15Rα signaling pathway is activated in skeletal muscle in response to a session of resistance exercise.

[Infectious diseases and use of health care resources in children less than 2 years-old who attend kindergarten]. / Enfermedad infecciosa y consumo de recursos sanitarios en menores de 2 años que acuden a guarderías.

INTRODUCTION AND OBJECTIVES: Parents often ask paediatricians for advice about the best way to care for their children. There are discrepancies in the literature on this subject. The objective of this study is to evaluate the influence of attending kindergartens on the risk of acute infections and the use of health care resources in children less than 24 months. POPULATION AND METHODS: A prospective longitudinal study was conducted on two cohorts of children 0-24 months (born between 1 January and 30 September 2010), who were grouped according to whether they attended kindergarten or not, and were usually seen in 33 pediatric clinics of the Principality of Asturias Public Health Service. RESULTS AND CONCLUSIONS: A total of 975 children were studied, of whom 43.7% attended a kindergarten at 24 months. Attending kindergarten increases the risk of pneumonia by 131%, recurrent wheezing by 69%, bronchitis by 57%, and otitis media by 64%. Early exposure to kindergarten increases the risk of pneumonia from 2.31 to 2.81, and the mean emergency room visits from 1 to 2.3. The mean antibiotic cycle is 1.7 in children who do not go to kindergarten, 3.4 if started within the first 6 months, and 2 if they start at 18 months. Day-care attendance is a risk factor of infectious diseases that increases if attending kindergartens from an early age.

Antioxidant activity, color, carotenoids composition, minerals, vitamin C and sensory quality of organic and conventional mandarin juice, cv. Orogrande.

The effects of organic farming on antioxidant activity, CIE L*a*b* color, carotenoids composition, minerals contents, vitamin C and sensory quality of Orogrande mandarin juices were studied. Independent of the farming type, mandarin juices can be considered as good source of some important nutrients, such as potassium and antioxidant chemicals, for example, ß-cryptoxanthin. Organic farming of mandarin resulted in juices with higher antioxidant activity, total carotenoids concentrations, minerals (Ca, K and Fe) contents, vitamin C content, more appealing and intense orange color and better sensory quality. For instance, organic Orogrande juice contained significantly (p < 0.001) higher total carotenoids content (22.7 ± 0.3 mg/L) than conventional juice (15.7 ± 0.4 mg/L); a similar pattern was observed for the antioxidant activity, with values being 0.076±0.004 and 0.053 ± 0.003 mM Trolox m/L in organic and conventional juices, respectively. A trained panel stated that organic Orogrande juices had higher intensities of orange color, fresh mandarin and floral aromas than conventional juices.

Sacroileítis piógena en el niño y el adulto joven. A propósito de tres casos / Pyogenic sacroiliitis in the child and young adult. Three case reports

La sacroileítis piógena es una patología inusual que supone menos del 2% del total de las artritis sépticas y constituye un reto diagnóstico para el clínico debido a la diversidad de manifestaciones clínicas, la baja especificidad de las pruebas analíticas y la limitación de la radiología simple en fases precoces, lo que retarda el establecimiento de una antibioterapia precoz, que ha demostrado ser el tratamiento de elección en estos pacientes. Su diferente fisiopatología en el niño la transforma en una entidad diferenciada de la del adulto. Presentamos tres casos de sacroileítis séptica en la edad infanto-juvenil, de los cuáles dos evolucionaron favorablemente con tratamiento médico y uno precisó tratamiento quirúrgico con complicaciones postoperatorias (AU)

Pyogenic sacroiliitis is a rare condition with prevalence of septic arthritis lower than 2%, and represents a diagnostic challenge for clinicians due to the variety of clinical expressions, low analytic specificity and the limitations of simple x-rays in the early stages, leading to delayed antibiotic therapy which is the treatment of choice for these patients. The inherent characteristics of its pathophysiology in children makes it distinguishable from that in adults.We report three cases of children and adolescents, two of whom improved clinically after medical treatment, and one required surgical debridement with a postoperative complication (AU)

Evaluation of the flora of northern Mexico for in vitro antimicrobial and antituberculosis activity.

The aim of the present study was to evaluate the potential antimicrobial activity of 14 plants used in northeast México for the treatment of respiratory diseases, against drug-sensitive and drug-resistant strains of Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae type b and Mycobacterium tuberculosis. Forty-eight organic and aqueous extracts were tested against these bacterial strains using a broth microdilution test. No aqueous extracts showed antimicrobial activity, whereas most of the organic extracts presented antimicrobial activity against at least one of the drug-resistant microorganisms tested. Methanol-based extracts from the roots and leaves of Leucophyllum frutescens and ethyl ether extract from the roots of Chrysanctinia mexicana showed the greatest antimicrobial activity against the drug-resistant strain of Mycobacterium tuberculosis; the minimal inhibitory concentration (MIC) were 62.5, 125 and 62.5 microg/mL, respectively; methanol-based extract from the leaves of Cordia boissieri showed the best antimicrobial activity against the drug-resistant strain of Staphylococcus aureus (MIC 250 microg/mL); the hexane-based extract from the fruits of Schinus molle showed considerable antimicrobial activity against the drug-resistant strain of Streptococcus pneumoniae (MIC 62.5 microg/mL). This study supports that selecting plants by ethnobotanical criteria enhances the possibility of finding species with activity against resistant microorganisms.

Seven-year review of paediatric bacteraemias diagnosed in a Spanish university hospital.

UNLABELLED: This study analysed the clinical and bacteriological patterns of paediatric bacteraemia in a university hospital, by a review of 213 episodes over a period of 7 y. Streptococcus pneumoniae was the most frequent aetiological agent after the neonatal period and Streptococcus agalactiae in neonatal sepsis. Almost half of pneumococci and meningococci were penicillin non-susceptible. Four neonatal deaths attributed to bacteraemia were recorded. CONCLUSION: Streptococcus pneumoniae is the leading cause of community-acquired bacteraemia. Mortality due to bacteraemia in children without underlying conditions is rare.

This paper presents a patient with multiple condyloma and a Buschke-Lowenstein tumor in the groin with clinical aspect of a squamous carcinoma. Malignity was histologically ruled out in this case. Lesions were treated by surgery and during the postoperative period, the patient was treated with interferon alpha i.m. at a rate of 9 x 10(6) UI/day three times a week for 3 weeks. One year after the treatment, the patient had not shown any relapse.

[Nasal allergenic provocation test]. / Prueba de provocación alergénica nasal.

This is a method to evaluate both specific sensitivity to allergens in the nasal mucosa, IgE-mediated hypersensitivity, and antiinflammatory and antiallergic drugs efficacy, whose objectives are for research in diagnosis and treatment. The method is based in allergen extracts delivery in the nasal mucosa and the post-challenge measurement of rhinitis symptoms, vasoactive mediators release quantification and nasal obstruction degree evaluated by rhinomanometry. Nasal allergen challenge is a procedure of diagnostic and therapeutic evaluation usefulness, that must be performed in selected patients, in adequate facilities, by experts physicians, with standardised allergen dosages, in an specific nasal area, with objective measurements (rhinomanometry, mediators and secretions of the allergic response) and symptoms scoring that allow get reliable results in patients with allergic rhinitis under study.

[Prevalence of human immunodeficiency virus (HIV) infection and its relationship with other sexually transmitted diseases in a group of prostitutes from Huixtla, Chiapas]. / Prevalencia de la infección por el virus de la inmunodeficiencia humana (VIH) y relación con otras enfermedades transmitidas sexualmente en un grupo de prostitutas en Huixtla, Chiapas.

We investigated the HIV prevalence rate in 106 female prostitutes residing in Huixtla, State of Chiapas, which is a small town in the southeastern part of Mexico, from February of 1989 to January of 1990. We used an immunoenzymatic method (Serodia). The mean age was 35 years ranging from 17 to 43. Sixty six women (62%) were from Central America, and the remainder had been born in Mexico. The HIV antibody was not detected in the women, but 39 (37%) had a sexually transmitted disease: the more frequent were condolomatosis, candidiasis, trichomoniasis, gonorrhea, and syphilis.
