The impact of frailty on intra-hospital survival in older patients with COVID-19 infection: the importance of early identification. SEMI-COVID National Registry.

BACKGROUND: Emerging evidence suggests that frailty may be a significant predictor of poor outcomes in older individuals hospitalized due to COVID-19. This study aims to determine the prognostic value of frailty on intrahospital patient survival. METHODS: This observational, multicenter, nationwide study included patients aged 70 years and older who were hospitalized due to COVID-19 in Spain between March 1 and December 31, 2020. Patient data were obtained from the SEMI-COVID-19 Registry of the Spanish Society of Internal Medicine. Frailty was assessed using the Clinical Frailty Scale. The primary outcome was hospital survival. Cox proportional hazards models were used to assess predictors of survival. RESULTS: A total of 1,878 participants (52% men and 48% women) were included, with 1,351 (71.9%) survivors and 527 (28.1%) non-survivors. The non-survivor group had higher mean age (83.5 vs. 81 years), comorbidities (6.3 vs. 5.3 points on the Charlson index), degree of dependency (26.8% vs. 12.4% severely dependent patients), and frailty (34.5% vs. 14.7% severely frail patients) compared to survivors. However, there were no differences in terms of sex. Our results demonstrate that a moderate-severe degree of frailty is the primary factor independently associated with shorter survival [HR 2.344 (1.437-3.823; p<0.001) for CFS 5-6 and 3.694 (2.155-6.330; p<0.001) for CFS 7-9]. CONCLUSION: Frailty is the main predictor of adverse outcomes in older patients with COVID-19. The utilization of tools such as the Clinical Frailty Scale is crucial for early detection in this population.

[Impact of days elapsed from the onset of symptoms to hospitalization in COVID-19 in-hospital mortality: Time matters]. / Impacto de los días transcurridos desde el inicio de los síntomas hasta la hospitalización en la mortalidad hospitalaria por COVID-19: el tiempo importa.

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.

[Acarbose and propofol: a dangerous combination?]. / Acarbosa y propofol: ¿una peligrosa combinación?

Hepatotoxicity is a rare complication following the use of propofol and can be potentially serious if an early diagnosis is not made. Propofol is being increasingly used in daily practice, not only in surgery, but also in outpatient sedation procedures, such as endoscopy. Acarbose is a well-known drug used in type 2 diabetes treatment, particularly in the early phase. A case is reported on a patient who suffered an acute hepatitis secondary to the use of propofol in ophthalmology surgery, a hepatitis probably enhanced by prior use of acarbose, a drug that also can cause hepatotoxicity. An early diagnosis and it was resolved without complications. This case could contribute to improve pre-anesthetic evaluation of patients who will be undergoing sedation with propofol in order to avoid the possible appearance of hepatitis.

[Parasitosis (I). Imported heart and lung lesions]. / Parasitosis (I). Lesiones cardiacas y pulmonares importadas.

Imported parasitoses are an uncommon condition in our setting, although recently, the increase of migratory flow has been leading to an increase in the detected cases of these diseases. This fundamentally occurs in immigrants from tropical zones where these conditions are generally endemic. However, imported parasitoses are being increasingly diagnosed in Western persons who have lived in the tropics for different reasons. When examining a subject with cardiovascular syndromes with a possible parasitic origin, it could be useful to classify the possible geographic zone of origin in order to perform disease screening. Then, if the problem is mainly respiratory, it would be well to first rule out the existence of tuberculosis in the case of long stays and to individual the diagnosis according to the geographic area, season of the year, type of exposure and symptoms presented, in the case of shorter stays.

[Clinical trial comparing efficacy and safety of four highly active antiretroviral therapy (HAART) in antiretroviral-naive treatment with advanced HIV infection]. / Ensayo clínico comparativo de eficacia y seguridad de cuatro pautas de tratamiento antirretroviral de alta eficacia (TARGA) en pacientes naive con infección por VIH avanzada.

BACKGROUND: Comparison of efficacy and safety of four highly active antiretroviral therapy regimens (HAART) including two nucleoside analogues (NA) and a protease inhibitor (PI) in HIV positive patients with advanced infection and antiretroviral naive. PATIENTS AND METHODS: Multicenter, randomized and open labeled clinical trial in ten community hospitals of Castilla-La Mancha and Madrid. Regimen 1 contains zidovudine (AZT), lamivudine (3TC) and indinavir (IDV) regimen 2 includes AZT, 3TC and ritonavir (RTV), regimen 3 was didanosine (DDI), estavudine (D4T) and IDV, and regimen 4 included DDI, D4T and RTV. Decrease in viral load of HIV (VC) has been assessed as primary endpoint and as secondary one, the increase of the numbers of CD4 lymphocytes, percentage of disease progression, adverse reactions and adherence. Measurements were made at baseline visit and at 6, 12, 24, 36 and 48 weeks. RESULTS: A total of 98 patients with a mean baseline CD4 count of 122 x 10(6)/l (range of 5-340) and a baseline viral load of 5.1 log copies/ml were included. At 48 weeks, a mean increase of the CD4 and decrease of the viral load without significant difference between the 4 regimens (103 cells/2.62 log in regimen 1; 169 cells/2.86 log in regimen 2; 171 cells/2.56 log in regimen 3 and 141 cells/1.71 log in regimen 4) were observed in the analysis of the patients in treatment. Treatment was discontinued due to adverse reactions: 24% in regimen 1, 48% in regimen 2, 26% in regimen 3 and 32% in regimen 4, without significant difference. Analyzing by PI groups, 41% of the patients with RTV and 25% of those with IDV discontinued treatment due to adverse effects. There was withdrawal from treatment due to disease progression in 7% of the RTV patients and in 9% of IDV patients. CONCLUSIONS: In the HIV positive patients with advanced infection, efficacy between the four regimens of HAART is similar, but there is a tendency to require more withdrawal due to adverse effects in the RTV group than in those of IDV, the two used as single PI.
