RESUMEN
Background: COVID-19 shows different clinical and pathophysiological stages over time. Theeffect of days elapsed from the onset of symptoms (DEOS) to hospitalization on COVID-19prognostic factors remains uncertain. We analyzed the impact on mortality of DEOS to hospital-ization and how other independent prognostic factors perform when taking this time elapsedinto account. Methods: This retrospective, nationwide cohort study, included patients with confirmed COVID-19 from February 20th and May 6th, 2020. The data was collected in a standardized online datacapture registry. Univariate and multivariate COX-regression were performed in the generalcohort and the final multivariate model was subjected to a sensitivity analysis in an earlypresenting (EP; < 5 DEOS) and late presenting (LP; ≥5 DEOS) group. Results: 7915 COVID-19 patients were included in the analysis, 2324 in the EP and 5591 in theLP group. DEOS to hospitalization was an independent prognostic factor of in-hospital mortalityin the multivariate Cox regression model along with other 9 variables. Each DEOS incrementaccounted for a 4.3% mortality risk reduction (HR 0.957; 95% CI 0.93---0.98). Regarding variationsin other mortality predictors in the sensitivity analysis, the Charlson Comorbidity Index onlyremained significant in the EP group while D-dimer only remained significant in the LP group. Conclusion: When caring for COVID-19 patients, DEOS to hospitalization should be consideredas their need for early hospitalization confers a higher risk of mortality. Different prognosticfactors vary over time and should be studied within a fixed timeframe of the disease.

BACKGROUND: Spain has been one of the countries most affected by the COVID-19 pandemic. OBJECTIVE: To create a registry of patients with COVID-19 hospitalized in Spain, in order to improve our knowledge of the clinical, diagnostic, therapeutic, and prognostic aspects of this disease. METHODS: A multicentre retrospective cohort study, including consecutive patients hospitalized with confirmed COVID-19 throughout Spain. Epidemiological and clinical data, additional tests at admission and at seven days, treatments administered, and progress at 30 days of hospitalization were collected from electronic medical records. RESULTS: Up to June 30th 2020, 15,111 patients from 150 hospitals were included. Their median age was 69.4 years (range: 18-102 years) and 57.2% were male. Prevalences of hypertension, dyslipidemia, and diabetes mellitus were 50.9%, 39.7%, and 19.4%, respectively. The most frequent symptoms were fever (84.2%) and cough (73.5%). High values of ferritin (73.5%), lactate dehydrogenase (73.9%), and D-dimer (63.8%), as well as lymphopenia (52.8%), were frequent. The most used antiviral drugs were hydroxychloroquine (85.6%) and lopinavir/ritonavir (61.4%); 33.1% developed respiratory distress. Overall mortality rate was 21.0%, with a marked increase with age (50-59 years: 4.7%, 60-69 years: 10.5%, 70-79 years: 26.9%, ≥80 years: 46.0%). CONCLUSIONS: The SEMI-COVID-19 Network provides data on the clinical characteristics of patients with COVID-19 hospitalized in Spain. Patients with COVID-19 hospitalized in Spain are mostly severe cases, as one in three patients developed respiratory distress and one in five patients died. These findings confirm a close relationship between advanced age and mortality.

In the last three years, the development of a profound reorganization of university teachings has made it possible to comply with the commitments of the Declaration of Bologna and to adapt all teaching to the new structure of the degree program that will be introduced in October 2010. Along these lines (Order ECI/332/2008), the requirements that must be fulfilled by the university degrees to be able to practice the medical profession have been established. In the new study plans, acquisition of skills by the students is given priority and emphasis is placed on the learning methods of these skills, and on the procedures to evaluate their acquisition. The European Credit Transfer System (ACTS), (between 25 and 30h), is the measurement unit that reflects the learning results. Furthermore, acquisition of clinical skills is promoted through the obligatory performance of pre-professional practices, in form of a period of independent clinical rotation and with a final evaluation of the skills, in health care centers, hospitals, and other care centers. In the upcoming years, it will be verified if this curriculum modernization of the study plans improves the professional practice of the new physicians.

Colchicine is an alkaloid that has been successfully used for a long time in the treatment of acute gout episodes. It's efficacy lies in its inhibition of inflammation cell migration and in the action of specific cytokines, as well as of the production of lactic acid and deposition of uric acid in affected tissues. Colchicine toxicity is rare but may entail highly negative consequences for health unless a rapid gastric decontamination with stomach lavage and active carbon is carried out, and adequate support measures are taken as wellas appropriate hydration and electrolyte replacement. We present the case of a patient who was admitted to hospital after ingesting colchicine with suicidal intention. Colchicine inhibits cell division, which explains its distinct toxicity stages. The lack of proportion existing between ingested dose and clinical impact may result from concomitant treatment with other drugs or from peculiarities in its metabolism.

OBJECTIVE: To evaluate the pattern of erythropoietin (EPO) and some proinflammatory cytokines in the anemia of chronic disorders (ACD) secondary to infection. METHODS: Sequential determination in serum of interleukin-1 beta (IL-1 beta), necrosis tumoral factor alpha (TNF-alpha), gamma interferon (IFN-gamma), interleukin-6 (IL-6), and erythropoietin (EPO) in 25 patients with chronic bacterial infectious diseases and ACD criteria. We evaluated the relationship of these mediators with the anemia and the iron metabolism. RESULTS: Serum EPO levels significatively decreased compared with initial values, and the last control was in normal rank (18.04 +/- 19.10 vs. 8.56 +/- 4.72 UI/mL; p < 0.001; normal rank: 4-15 mUI/mL). In the first control, there was a negative and non significative correlation between the EPO levels and the hemoglobin concentration (r = -0.115, NS), reaching significance in the last control (r = -0.446; p < 0.05). There was negative correlation between the hematocrit and TNF-alpha levels (r = 0.467; p < 0.05) and between the haemoglobin values and the log of serum TNF-alpha (r = 0.424; p < 0.001). An inverse correlation between the IL-6 levels and both, the hemoglobin concentration and the serum iron was found, and there was a direct correlation between this cytokine values and the EPO levels. CONCLUSIONS: Blunted response of erythropoietin and the action of TNF may contribute to the pathogenesis of ACD secondary to infection. Positive correlation between IL-6 and EPO suggest a proerythropoietic action of IL-6 in response to the anemia.

Coeliac disease can by defined as a chronic disease characterized by a typical mucosal lesion of the small intestine and an impaired nutrient absorption which improves on withdrawal of gluten from the diet. The prevalence rate has increased over the last decades and just 1/3 of cases are diagnosed in childhood. There is a striking association with class II histocompatibility antigens, HLA-DR3 and HLA-DQ2. Cellular immune response mediated by intraepithelial and lamina propria lymphocytes is the primary event in the small intestine damage. Up to 50% of adult coeliac patients don't present intestinal symptoms being more frequent subclinic forms. The immunological markers of coeliac disease are antigliadin, antireticulin and antiendomysial antibodies, being the last one the most specific. Mortality of coeliac patient is increased mainly for malignancies, being the most frequent the intestinal T lymphoma.

A cross-sectional study was conducted at diagnosis of HIV infection in 42 patients aged > or = 60 years attended in two hospitals in the Madrid Community. Clinical and epidemiologic characteristics were retrospectively analyzed. Mean age was 64 years, 38 patients (90.4%) were males, and 24 (57.1%) met the AIDS criteria at diagnosis. Risk behaviour: 14 (33.3%) heterosexuals, 13 (30.9%) homosexuals, 3 (7.1%) bisexuals, 3 (7.1%) had received blood derivatives, 2 (4.7%) transfused patients, 1 (2.3%) parenteral drug abuser, 1 (2.3%) others and 5 (11.9%), unknown. In 18 (42.8%) patients there was a delay of diagnosis of 7.5 +/- 1.2 months (range: 1.5-24 months). These patients had lymphocyte counts lower than those diagnosed without delay (102 +/- 20 vs 262 +/- 67.10(9)/l, p < 0.01). Patients without AIDS criteria had a likelihood of 15.4% of progression towards AIDS at one year. The survival rate of patients with AIDS at one year was 50.1%. Patients with AIDS and diagnostic delay had a survival rate at one year lower than that in patients without diagnostic delay (30.7% vs 77.8%, p = 0.03). In summary, a predominant sexual transmission was found in our series. Delay of diagnosis entails a greater clinical and immunologic deterioration and a lower survival at one year. Early diagnosis and therapy with anti-retroviral agents might induce a longer survival in these patients.

A descriptive cross-sectional study was conducted on the prevalence and histologic characteristics of renal lesions found in the autopsies of 85 patients with HIV infection: also, a retrospective analysis of clinico-biological characteristics in 56 of these patients in order to establish the factors associated with the histological findings. A total of 85 autopsies were made from 1985 to 1993; 50 autopsies (58.8%) showed renal changes: 23 (27%) infections, 13 (15.2%) acute tubular necrosis (ATN), 6 (7%) tumors, 5 (5.8%) intersticial nephritis (IN), 5 (5.8%) nephrocalcinosis (NC), 10 (11.7%) others. In an additional study: group IIc (n = 37, study group with nephropathy) had a higher incidence in the hepatitis B surface marker (HBsAg) than in group Ic (n = 19, control group, without nephropathy) (0 vs 10, p < 0.05). The presence of disseminated mycobacteriosis in the autopsy was significantly higher in the group with nephropathy than in the group without nephropathy (11 vs 1, p < 0.05). No consistent data were observed between the clinical diagnosis of nephropathy and autopsic findings. In summary, a high incidence of nephropathy was found in the autopsies of HIV infected patients, although it was not previously suspected. Renal lesions in autopsies of HIV infected patients had a tubular-intersticial predominance over glomerular lesions. The use of potentially nephrotoxic drugs, the presence of HBsAG, and some opportunist infections apparently influenced on the development of renal lesions among these patients.

The hypophyseal-adrenal-ovarian axis was studied in 29 women of childbearing age with systemic lupus erythematosus, as well as in a control group of 14 healthy women. Hormonal levels were measured on days 7th and 21st of menstrual cycle. Women with systemic lupus erythematosus had not significatively lower testosterone levels, but progesterone and 17-alfa-hydroxiprogesterone levels were markedly lower when compared to controls. These facts suggest a decrease in progesterone levels, which could act as a predisposing factor for lupic disease.
