Background: Solid Organ Transplant recipients (SOTR) appear to be at particular high risk for critical COVID-19 due to immunosuppressive drugs and comorbidities. We report the first description of clinical course and short-term outcomes of kidney and liver transplant recipients with confirmed COVID-19 in Mexico. Objective: The objective of this paper was evaluate the clinical course of transplant patients with COVID-19 infection. Methods: We retrospectively evaluated SOTR (kidney and liver) over 18 years of age with confirmed diagnosis of COVID-19 from tertiary care centers in Mexico. Results: Data from 45 kidney transplant recipients were recorded. Median (IQR) age was 43 (IQR 25-70) years. Admission to hospital was required in 37 (75.5 %) patients, of which 8 (16.3%) were hospitalized at Intensive Care Unit (ICU). Acute kidney injury (AKI) stage was documented in 33 (67%) patients. The time of hospitalization was 8 (IQR 6-12) days. Six patients died (12.2%). Additionally, data from 10 liver transplant recipients were included. During their evolution, 5 / 10 required hospital admission and there were no deaths in this group. Conclusions: Transplant recipients show a higher fatality rate and complications from SARS-CoV-2 infection; more studies are needed to identify prognostic factors and effective anti-SARS-CoV-2 therapies.

The Covid-19 pandemic caused an unusual population mortality rate. This paper aims to determine a causal relationship and its incidence between the Technical Efficiency (TE) of health systems and the Covid-19 mortality rate. Using the Data Envelopment Analysis (DEA) methodology and the OLS, GLS and 2SLS adjustment methods, in 108 countries grouped according to per capita health expenditure, it was found that a 1% increase in the TE of the health systems of the analyzed countries reduces the number of deaths from Covid-19 by between 61 and 127 per hundred thousand inhabitants, concluding that the efficiency of expenditure was transcendental in the prevention of mortality caused by the pandemic.

Objective. To determine the relative risk of a lethal outcome associated with chronic degenerative conditions in patients with COVID-19. Methods. A cohort study was conducted using electronic medical records belonging to patients who tested positive for COVID-19 on RT-PCR while receiving care as outpatients or inpatients in a social security system facility between March 2020 and March 2021. Two study groups were formed. The exposed group was divided into four subgroups, each of which was diagnosed with one and only one chronic condition (diabetes, hypertension, obesity, or chronic kidney disease); the unexposed group was obtained from the medical records of patients without comorbidities. A total of 1 114 medical records were examined using simple random sampling. Once the minimum sample size was reached, the relative risk was calculated for each chronic condition. Combinations of two, three, and four conditions were created, and each of them was included in the analysis. Results. In the absence of a chronic degenerative condition, the prevalence of a lethal outcome from COVID-19 is 3.8%; in the presence of type 2 diabetes mellitus, 15.8%; in the presence of arterial hypertension, 15.6%; and in the presence of obesity, 15.0%. For diabetes and hypertension combined, the prevalence of a lethal outcome is 54.1%; for diabetes and obesity combined, 36.8%, and for obesity and hypertension combined, 28.1%. Conclusion. In patients with COVID-19, the relative risk of a lethal outcome is 4.17 for those with diabetes, 4.13 for those with hypertension, and 3.96 for those with obesity. For two chronic conditions combined, the relative risk doubles or triples. The relative risk of a lethal outcome is 14.27 for diabetes plus hypertension; 9.73 for diabetes plus obesity, and 7.43 for obesity plus hypertension. Chronic conditions do not present alone; they generally occur together, hence the significance of the relative risks for lethal outcomes presented in this paper. [ABSTRACT FROM AUTHOR]

This paper presents a method to estimate excess mortality where national data are missing for some or all of the coronavirus disease 2019 (COVID-19) pandemic period, but subnational data exist, such as in Argentina. By making use of the stability of the regional distribution of deaths, data on deaths in Córdoba province were used to project excess deaths in Argentina from March 2020 up to the end of 2021. The number of excess deaths was estimated at 134 504, which is 14.8% higher than the reported number of COVID-19 deaths in Argentina for the same time period. [ABSTRACT FROM AUTHOR]

Faced with a pneumonia outbreak in 59 suspected patients at a local seafood market in Wuhan, China, the first case of a novel coronavirus was laboratory-confirmed on December 1, 2019. On January 7, 2020, a new type of virus of the family Coronaviridae called SARS-CoV-2 –causative agent of COVID-19– was identified. The few initial reports restricted involvement to the lower respiratory tract. Both, disease progression and build-up of scientific evidence, proved the crucial role played by cardiovascular involvement in the development and prognosis of the infection. Age is an independent predictor of mortality and an association between pre-existing cardiovascular disease and severe forms of the disease has been demonstrated. Cardiovascular involvement may be either direct or indirect; acute myocardial injury, myocarditis, acute myocardial infarction, heart failure, arrhythmias and venous embolic events stand out among others. Adverse effects of treatment for cardiac complications and drug testing in therapeutic protocols may be contributing aspects. This paper addresses cardiovascular involvement due to COVID-19.

Objective: The aim of this paper was to analyse the association of demographic, clinical and pharmacological risk factors with the presence of SARS-COV-2 virus infection, as well as to know the variables related to mortality from COVID-19 in nursing home (NH) residents. Design: Retrospective case–control study. The study variables of those residents who acquired the infection (case) were compared with those of the residents who did not acquire it (control). A subgroup analysis was carried out to study those variables related to mortality. Site: Nursing homes in the region of Guipúzcoa (Spain). Participants and interventions: 4 NHs with outbreaks of SARS-CoV-2 between March and December 2020 participated in the study. The infectivity and, secondary, mortality was studied, as well as demographic, clinical and pharmacological variables associated with them. Data were collected from the computerised clinical records. Main measurements: Infection and mortality rate. Risk factors associated with infection and mortality. Results: 436 residents were studied (median age 87 years (IQR 11)), 173 acquired SARS-CoV-2 (39.7%). People with dementia and Global Deterioration Scale ≥6 were less likely to be infected by SARS-CoV-2 virus [OR = 0.65 (95% CI 0.43–0.97; p
