RESUMO
Objective: This systematic review aims to understand the problems associated with lockdown and the various conditions of Covid-19 infection and to help prepare athletes and exercise enthusiasts for the safe resumption of sport in a manner that promotes wellness, healthy competition, and a sports industry that survives the current situation. This systematic review was carried out, following the recommendations of the currently pre-established reporting elements for systematic reviews and meta-analyses. The following databases were consulted: ISI Web of Science (WOS), Scopus and Google Scholar. This review includes a total of 19 articles. News: The results are presented based on three predominant themes: (1) psychological impact produced by SARS-CoV-2; (2) post-Covid-19 cardiac abnormalities and (3) protocols for an adequate return to physical practice. Prospects and projects: Most of the protocols shown by the various papers are consistent in terms of duration and number of phases. Based on this, the safe return to practice protocol can be divided into four stages of seven days in each phase in order to progress according to the symptoms perceived. In each phase, the physiological demand and efforts necessary to cover the proposed activities are increased until optimal physical condition is recovered.

RESUMO
OBJETIVO Describir la tendencia de las consultas de urgencia odontológica ambulatoria registrada en la población atendida en la red pública de salud en Chile entre los años 2017 y 2020. MATERIALES Y METODOS Diseño de estudio ecológico. Se evaluaron las consultas de urgencia odontológica ambulatoria obtenidas del Registro Estadístico Mensual (REM) del Ministerio de Salud de Chile entre los años 2017 y 2020. Se calculó la tasa de consulta por urgencia odontológica ambulatoria (UOA) considerando el total de consultas de urgencias con Garantía explícitas en salud en el numerador y la población beneficiaria registrada por el Fondo Nacional de salud en el denominador, amplificado por 1000 para cada año de estudio. Las tasas se especificaron por sexo, grupo etario (<20 años; 20 a 64 años y 65 y más años), y zona geográfica de Chile (zona norte, centro y sur). RESULTADOS Se registraron un total de 27.639.889 consultas odontológicas en la red pública de atención de salud en el país, de estas, 1.345.390 corresponden a consultas por UOA. Se observó una disminución de la tasa de consulta por urgencia odontológica ambulatoria hacia el año 2020 (variación porcentual de -17,93%). La tasa de consultas es levemente mayor en mujeres, en edades entre 20 a 64 años y en la zona norte y sur del país. CONCLUSION Se observa una disminución sostenida en la tasa de consultas por UOA en la red pública de salud del país, lo que podría reflejar la existencia de un mayor acceso de la población a resolver los problemas de salud bucal en el nivel primario de atención asociado al desarrollo de diferentes programas de alud bucal. Sin embargo hay que ser cautelosos con la interpretación considerando que durante el periodo Chile vivió un estallido social e hizo frente a la pandemia por COVID-19
AIM To describe the trend of outpatient dental emergency registered in the population attended in the public health system in Chile between 2017 and 2020. MATERIALS AND METODOS Ecological study design. Outpatient dental emergency obtained from the Statistical Registry (REM) of the Ministry of Health of Chile between 2017 and 2020 were evaluated. The consultation rate for outpatient dental emergency (OUA) was calculated considering the total number of emergency consultations with Explicit health guarantees in the numerator and the beneficiary population registered by the National Health Fund in the denominator, amplified by 1,000 for each year of study. The rates were specified by sex, age group (<20 years; 20 to 64 years and 65 years and over), and geographical area of Chile (north, center and south). RESULTS A total of 27,639,889 dental consultations were registered in the public health care network in the country, of these, 1,345,390 correspond to consultations by UOA. A decrease in the outpatient dental emergency consultation rate was observed towards the year 2020 (percentage variation of -17.93%). The consultation rate is slightly higher in omen, between the ages of 20 and 64, and in the north and south of the ountry.CONCLUSION A sustained decrease in the consultation rate for UOA in the country's public health system is observed, which could reflect the existence of a greater access of the population to solve oral health problems at the primary level of care associated to the development of different oral health programs. However, one must be cautious with the interpretation considering that during the period Chile experienced a social explosion and faced the COVID-19 pandemic

There are currently several commercialized products approved by the Food and Drug Administration and the European Medicines Agency based on the use of recombinant human BMP-2 for the treatment of non-unions long fractures and spinal fusion. However, the adverse effects recorded with the use of BMPs suggest the need for drug delivery carriers that allow reducing the required doses and improve their cost-effectiveness. Herein, we have developed a new osteoconductive scaffold that reduces the required doses of BMP-2 for promoting bone regeneration in an osteoporotic defect model. The composite is, in brief, a gelatin-based 3D scaffold reinforced with either calcium sulfate or hydroxyapatite as an inorganic osteoconductive biomaterial. To this end, the organic/inorganic composite systems showed high hydration capacity and good in vitro degradability. The incorporation of 7.5% (m/v) ceramic compounds resulted in scaffolds with stiffer Young modulus (179 and 75 kPa for CaSO4_7 and HA_7, respectively) than bare gelatin hydrogels (48 kPa). Studies with human bone-marrow derived mesenchymal stem cells (hBM-MSCs) revealed that the 3D scaffolds promote cell adhesion and proliferation along with osteogenic differentiation capabilities. Specifically, downregulation of stemness (Nanog, Oct4) genes and upregulation of osteogenic markers (ALP, Col1a1, Fmod) by two fold were observed over 10 days under basal culture conditions. Promisingly, the sustained in vitro release of BMP-2 observed from the porous reinforced scaffolds allowed us to address the critical-sized osteoporotic mice calvarial defects with a relatively low growth factor doses (600 ng BMP-2/scaffold) compared to conventional doses at 2-15 micrograms. Overall, this study demonstrates the promising potential of osteoconductive gelatin/calcium bioceramics composites as osteogenic growth factors delivery carriers for bone-regeneration via ultra-low growth factor doses.

BACKGROUND: The Homeostatic Measurement Assessment-Insulin Resistance (HOMA-IR) is a recognized and validated method which uses the levels of fasting glucose in blood and insulin of patients to evaluate the insulin resistance. AIMS: The purpose of the present study was to assess the cut-off values for anthropological variables to identify the (HOMA-IR) index in female participants of a physical exercise program. In addition, the association and prediction of insulin resistance by anthropological variables was studied. METHODS: A total of 143 participants (45.64 ± 13.17 years) volunteered for this study. Clinical data were collected by means of a self-reported questionnaire. Body weight and BMI were assessed by bioelectrical impedance analysis and skinfold thickness was taken using a caliper. Girths were assessed with a flexible metallic tape measures and finally, the HOMA-IR was calculated by the formula as follows: fasting plasma insulin ((µU/ml) x fasting plasma glucose (mmol/L). RESULTS: The outcomes of the study indicated that the AUC of anthropometrical variables for identifying HOMA-IR are reflected primarily in weight, waist-to-hip ratio, waist-to-thigh ratio, subscapular skinfold thickness, abdominal skinfold thickness, hip circumference, chest circumference, upper arm muscular girths (tensed and relaxed) (all, p ≤ 0.001), triceps skinfold thickness (p 109 cm (specificity: 99.2 waist circumference > 116 cm (specificity: 99.2 %) and abdomen skinfold < 8.8 (specificity: 97.6 %), predict the HOMA-IR in 35.29 %, 29.41 %, 23.53 % and 23.53 %, respectively. CONCLUSION: The present empirical study demonstrates that hip, chest and waist circumference on the one hand, and abdomen skinfold on the other hand are markers that are relevant to the identification of HOMA-IR index in females (Tab. 3, Ref. 33).

INTRODUCTION: In patients with prostate cancer, high NLR seems to be associated with worse survival. Abiraterone acetate (AA) is a new generation hormonal treatment that has shown to increase PFS and OS in mCRPC. MATERIAL AND METHODS: Retrospective analysis of patients treated with AA in our center (December 2012-September 2018). We analyzed the association of the NLR (< or ≥ 3) before and after 6 months of treatment with PSA response, PFS, OS, and hormone sensitivity prior to AA (< or> 12 months). RESULTS: We have treated 56 patients with a median age of 82 (62-94), of which 22 (39%) had NLR ≥ 3 before treatment. There is a statistically significant association between the NLR prior to treatment<3 and PSA response, OR=9,444, P=.001, and there was no association with the NLR at 6 months of treatment. Statistically significant differences were found between the groups of NLR

BACKGROUND: Patterns of sensitization to house dust mites depend on geographic area and are important in clinical practice. However, the role of molecular diagnosis is not currently defined. We sought to characterize a pediatric population by focusing on sensitization to different mite species and major mite components in order to assess the clinical relevance of sensitization to allergenic components in our practice. METHODS: Consecutive children with respiratory allergy sensitized to house dust mites (determined by skin prick test [SPT]) were recruited. We determined specific IgE to nDer p 1, rDer p 2, and rDer p 23 using ImmunoCAP and sIgE using ImmunoCAP-ISAC microarray. Patients were followed up for 3 years. RESULTS: A total of 276 children were recruited. The frequency of sensitization was 86.6% for nDer p 1, 79.3% for rDer p 2, and 75.8% for rDer p 23. Lepidoglyphus species was the most common storage mite detected by SPT. Twenty-six patients (9.4%) were not sensitized to Der p 1 or Der p 2. It is noteworthy that IgE binding to Der p 23 was positive in 14 (53.8%). Asthmatic patients, especially those with a persistent moderate-severe phenotype, more frequently recognized the 3 major allergens. CONCLUSIONS: Most patients with mite allergy were sensitized to the major allergens Der p 1, Der p 2, and Der p 23. Of the allergens evaluated, 5% were sensitized to Der p 23 but not to Der p 1 or Der p 2. Sensitization to Der p 23 should be considered in the diagnosis and treatment of mite allergy, especially in patients with moderate-severe asthma, because it may worsen the clinical phenotype.

We herein review the association between patients safety and simulation methods for medical education. This evidence should help to change the present paradigm in medical education, where there is still reticence towards this education method. A total of 20 papers on the subject were reviewed. Ninety percent of these articles conclude that simulation contributes to patient safety, 5% conclude that the evidence is uncertain and 5% conclude that the effects will be seen in the next decade. Thus, the majority of papers support the use of simulation in medical education as a method that improves patients safety.

BACKGROUND AND OBJECTIVES: The homologous group of sweet grasses belongs to the Pooideae subfamily, but grass pollen species from other subfamilies can also cause allergy, such as Cynodon dactylon (Chloridoideae) and Phragmites communis (Arundinoideae). C dactylon and P communis have not been included in the sweet grasses homologous group because of their low cross-reactivity with other grasses. The aims of this study were to investigate the profile of sensitization to C dactylon and P communis in patients sensitized to grasses and to analyze cross-reactivity between these 2 species and temperate grasses. METHODS: Patients were skin prick tested with a grass mixture (GM). Specific IgE to GM, C dactylon, P communis, Cyn d 1, and Phl p 1 was measured by ImmunoCAP. A pool of sera was used for the immunoblot assays. Cross-reactivity was studied by ELISA and immunoblot inhibition. RESULTS: Thirty patients had sIgE to GM. Twenty-four (80%) had positive results for C dactylon, 27 (90%) for P communis, 22 (73.3%) for nCyn d 1, and 92.9% for rPhl p 1. Bands were detected in the 3 extracts by immunoblot. Inhibition of GM was not observed with C dactylon or P communis by immunoblot or ELISA inhibition. When C dactylon or P communis were used in the solid phase, GM produced almost complete inhibition. CONCLUSIONS: Eighty percent of patients sensitized to grasses were also sensitized to C dactylon and 90% were sensitized to P communis. Sensitization to these species seems to be induced by allergens different to those in sweet grasses.

PURPOSE: To assess the incidence and clinical features of unexpected visual loss after removal of silicone oil (ROSO). PATIENTS AND METHODS: A retrospective cross-sectional observational study of 421 consecutive eyes, which underwent silicone oil removal at one institution over a 2-year period. RESULTS: Fourteen (3.3%) patients, (12 male, mean age of 53.1 years) suffered unexplained visual loss. In these eyes, the mean duration of silicone oil fill was 141 days (range 76-218). The mean loss of visual acuity was 3.7 (range 2-6) Snellen lines (SL) at 1 month, 3.5 (2-6) SL at 3 months and 2.91 (0-6) SL at 6 months. The change from preoperative visual acuity was statistically significant at all visits (P=0.02). Subgroup analysis of 20 fovea-sparing giant retinal tear (GRT) detachments, observed 10 (50%) cases of visual loss after ROSO. Electrodiagnostic testing suggested predominantly macular dysfunction, with optic nerve involvement in one case. Five of the 14 cases had variable recovery of vision. CONCLUSION: There is a 3.3% overall incidence of visual loss following ROSO with a high rate (50%) observed in maculae on GRT detachments. Although recovery of visual acuity is seen in a minority of cases, visual loss after ROSO remains a serious and unexplained concern for vitreoretinal surgeons.

BACKGROUND: Tomato allergies have been extensively studied but component-resolved in vivo diagnosis with purified allergens has yet to be performed. OBJECTIVES: To evaluate the prevalence of sensitization to Sola l 3 in a Mediterranean population, and to compare the resulting sensitization profile with that of individuals sensitized to tomato, peach, and/or purified lipid transfer protein (LTP). METHODS: Sola l 3 was purified, characterized, and used to prepare skin prick tests (SPTs). Two groups of patients were selected. Group 1 consisted of patients with at least 1 positive SPT to tomato, peach, or LTP mixture (marker extracts) who were subsequently tested with Sola l 3 (n = 280). Group 2 (prevalence study) consisted of patients who underwent simultaneous SPT with the 3 marker extracts and Sola l 3 (n = 658). Patients from either group who were positive to any of the 4 extracts were studied in detail (study group, n = 1 23). ELISA and immunoblot assays were performed in individuals with a positive SPT to Sola l 3 to detect the presence of specific IgE antibodies to this allergen. RESULTS: Prevalence of sensitization to Sola l 3 was 3.2% overall and 54.7% in tomato-positive patients. Most tomato-sensitized patients were asymptomatic. Symptoms were more common in Sola l 3-positive individuals. Sensitization to peach and the LTP mixture did not discriminate between Sola l 3-positive and Sola l 3-negative patients. CONCLUSIONS: This study confirms that LTP, not only from peach but also from other fruit and vegetables, including tomato, is an important allergen in the Mediterranean area. Sensitization to Sola l 3 is associated with more symptoms in tomato-sensitized patients.

This case report describes a case of hyperthyroidism as manifestation of an embryonal carcinoma, and illustrates the causes that led to it. The case describes a 33-year-old male patient who complained of chest pain, palpitations, mild dyspnoea, and weight loss. Blood analysis reveals high levels of human chorionic gonadotropin (833818 mlU/ml), T3 (16.90 pg/ml), and T4 (7.77 ng/dl), as well as a fall of TSH (0.01 ulU/ml). Physical examination and imaging procedures confirm the occurrence of a left testicular tumour associated with numerous lung, hepatic and retroperitoneal metastases. Treatment with carbimazol and propanolol is established to manage hyperthyroidism, and an urgent orchiectomy is performed; the histologic diagnosis confirms an embryonal carcinoma (organoid type), but the patient died unexpectedly 24 hours later after having suffered sudden dyspnoea, tachypnoea, and tachyarrhythmia. Hyperthyroidism is a rare manifestation of a testicular tumour that should be borne in mind with regard to the patient's symptomatology and HCG levels.

OBJECTIVE: To assess the oral health status and treatment needs of older adults, living in the Valparaiso Region of Chile. BASIC RESEARCH DESIGN: A random sample of 354 older adults, aged 60 years or older, living independently in the community were examined orally by calibrated examiners and underwent a structured oral health interview. Data collection extended from October 2006 to June 2007. RESULTS: This was a largely dentate population (80%) with a mean DMFT score of 21.6 (s.d. 5.7). While about 28% of the dentate sample had all their restorative needs unmet, 30.8% had all of their restorative needs met. Regarding periodontal health, 3.3% had sound periodontum; complex periodontal therapy (CPI 3-4) was needed by 43.1% of the sample. CONCLUSION: This study represents one of the largest data collections in oral health among older adults living in Chile. Participants seemed to have better oral health status than previously reported. Of particular relevance is the reduction of the decayed component and the increased number of sound teeth in the present sample. Participants also presented lower need for advance periodontal treatment. Yet, inequalities were apparent in the proportion of unmet restorative needs. Strategies to develop oral health care programmes focused on improving access to and use of preventive services for older adults are critical. Further research is indicated to get a more complete picture of the factors that shape the oral health of Chilean older adults.

Classification of bloodstream infections (BSIs) as community-acquired (CA), healthcare-associated (HCA) and hospital-acquired (HA) has been proposed. The epidemiology and clinical features of BSI according to that classification in tertiary-care (TH) and community (CH) hospitals were investigated in a prospective cohort of 821 BSI episodes from 15 hospitals (ten TH and five CH hospitals) in Andalucía, Spain. Eighteen percent were CA, 24% were HCA and 58% were HA. The incidence of CA and HCA BSI was higher in CH than in TH (CA: 3.9 episodes per 1000 admissions vs. 2.2, p <0.01; HCA: 5.0 vs. 2.9, p <0.01), whereas the incidence of HA BSI was lower (7.7 vs. 8.7, p <0.01). In CA and HCA BSI, the respiratory tract was more frequently the source in CH than in TH (CA: 30% vs. 15%; HCA: 20% vs. 9%, p ≤0.03). In HCA BSI, chronic renal insufficiency and tunnelled catheters were less frequent in CH than in TH (11% vs. 26% and 7% vs. 19%, p ≤0.03), although chronic ulcers were more frequent (22% vs. 8%, p 0.008). BSIs as a result of methicillin-resistant Staphylococcus aureus or Pseudomonas aeruginosa were very rare in CA episodes, although extended-spectrum b-lactamase-producing Escherichia coli (ESBLEC) caused a similar proportion of all BSIs in CA, HCA and HA episodes. Multivariate analysis revealed no significant difference in mortality rates in CH and TH. HCA infections should be considered as a separate class of BSI in both TH and CH, although differences between hospitals must be considered. CA BSIs were not caused by multidrug-resistant pathogens, except for ESBLEC.

Human infection by Cyclospora cayetanensis, namely cyclosporiasis, can cause a wide range of symptoms in immunocompetent patients, from mild to severe diarrhea. Immunocompromised patients can present with chronic diarrhea and it has been recognized as a cause of traveler's diarrhea. We report three patients who traveled from Chile to Peru, who presented upon returning with prolonged traveler's diarrhea. A literature review about cyclosporiasis is presented, with emphasis on the clinical, epidemiological, diagnostic and therapeutic aspects of this disease.

BACKGROUND: There is a lack of information on health expenses caused by readmissions among hematopoietic stem cell transplant (HSCT) recipients. We analyzed the rate, causes, and evolution of hospitalization after HSCT. METHODS: We retrospectively studied 140 consecutive patients who received an autologous HSCT (n = 107; 76.4%) or an allogeneic HSCT (n = 33; 23.6%) in our institution from May 2001 through September 2004. RESULTS: There were 45 readmissions in 28 patients (20%): three (10%) in the autologous and 25 (90%), in the allogeneic HSCT cohorts. The overall median age was 35.3 +/- 13.5 years and 54% were women. Hematologic diseases were: multiple myeloma (n = 1, 4%), myelodysplastic syndrome (n = 2, 7%), acute lymphoblastic leukemia (n = 2, 7%), aplastic anemia (n = 2, 7%), chronic myeloid leukemia (n = 3, 11%), non-Hodgkin's lymphoma (n = 4, 14%), Hodgkin's disease (n = 4, 14%) and acute nonlymphoblastic leukemia (n = 10, 38%). The length of stay for each readmission was 25 +/- 21 days. The median day of readmission was +62.5 (range = +19 to +987); however, 75% occurred between days +30 and +70. The causes of hospitalization were: infections (n = 24, 54%), due to the graft (n = 14, 31%), graft failure (n = 4, 9%), coagulation disorders (n = 2, 4%), and second neoplasm (n = 1, 2%). Mortality due to the transplant was 10 patients (14%) including: graft-versus-host disease (n = 3), sepsis (n = 3), thrombotic thrombocytopenic purpura (n = 1), and relapse (n = 3). CONCLUSIONS: Although there was a frequent use of hospital resources (20%) after HSCT with patients hospitalized for a median of 25 days, it was beneficial since there were 86% survivors at 36 months follow-up.
