Community-acquired pneumonia (CAP) represents a major health issue and ≈20% of the patients require in-hospital attention. The main objective of the study was to determine clinical-imaging features of CAP episodes requiring hospitalization. The secondary objectives were to determine the diagnostic yield of microbiological analyses and the medical complications. ⋯ The most frequently isolated microorganisms were influenza virus in 37 (10.9%) episodes and Streptococcus pneumoniae in 11 (3.2%). Most of the hospitalized CAP patients were elderly with consolidative radiological patterns. The causal agent could be identified in less than a quarter of the patients, with the influenza test being the method with the highest diagnostic yield.

Most countries in Latin America have already reported thousands of confirmed cases and vulnerable populations are the most affected by the coronavirus disease 2019 (COVID-19) pandemic. Preventive measures such as hygiene, social distancing, and isolation, essential to stop the spread of coronavirus, are difficult to accomplish for vulnerable populations due to their living conditions. Seroepidemiological surveys are assets to measure the transmission for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). ⋯ Hence, the high rate of undiagnosed people suggests that clinical criteria and epidemiological nexus should be considered. The high seroprevalence observed in the context of an intense epidemic in a vulnerable area might serve as a reference to other countries. This study contributes to future decision making by understanding population immunity against SARS-CoV2 and its relation to living conditions and foccus that comprehensive biosocial, household-level interventions are needed.

[Sarcopenia index in hospitalized patients with chronic obstructive pulmonary disease exacerbation].
Sarcopenia (loss of muscle mass and function) implies a worse prognosis. However, its diagnosis is complex and is not made in routine clinical care. A biomarker has been proposed as a surrogate estimator of skeletal muscle mass, the so-called sarcopenia index ([serum creatinine/cystatine C] x100) which is associated with prognostic features in various diseases including patients with stable chronic obstructive pulmonary disease (COPD). ⋯ In the correlation analysis, the index had statistically significant values with FEV1 (r = 0.23), PaCO2 (r = -0.30), bicarbonate (r = -0.31), dyspnoea (r = -0.25) and length of admission (r = -0.30). In patients admitted for COPD exacerbation, the sarcopenia index was related to prognostic characteristics, so that lower values were associated with longer duration of hospital admission, more dyspnoea and greater functional impairment. As this is an index associated with muscle mass, its determination may identify patients who could be the subject of a differentiated therapeutic plan.

Case Reports
Type 1 diabetes and subcutaneous insulin resistance syndrome treated with pancreas transplantation.
We present a case of subcutaneous insulin resistance syndrome, a rare entity, consisting of subcutaneous and intramuscular insulin resistance, with normal or almost normal sensitivity to insulin when administered intravenously. Its cause is unknown and its treatment is challenging. Our patient required a pancreas transplant.

The incidence of acute kidney injury (AKI) in hospitalized patients with COVID-19 is variable, being associated with worse outcomes. The objectives of the study were to evaluate the incidence, risk factors (considering demographic characteristics, comorbidities, initial clinical presentation and associated complications) and impact of AKI in subjects hospitalized for COVID-19 in two third-level hospitals in Córdoba, Argentina. A retrospective cohort study was conducted. ⋯ AKI was independently associated with higher mortality (3.32 [1.6-6.9], p = 0.001). In conclusion, the incidence of AKI in adults hospitalized for COVID-19 was 19% and had a clear impact on morbidity and mortality. The independent risk factors for AKI were: Age, CKD, BNCA and MV.
