Double jeopardy; What happens when an epidemic is followed by an earthquake?

A crisis is an immediate threat to the functioning of society, while disaster is an actual manifestation of a crisis. Both are now even more critically socially constructed. In the middle of battle with the COVID-19 pandemic, the Republic of Croatia's capital of Zagreb was afflicted with another disaster - two severe earthquakes. Restrictive public health measures were already in place, including restriction on public transport, travel between regions, closure of educational and other public institutions, alongside measures of physical distancing. Most previous cases of COVID-19 were centered in Zagreb, leading to concern of spreading the disease into disease-free communities. It seems that earthquakes did not have an effect on disease transmission - the number of COVID-19 cases remained stable through the 14-day incubation period, with a linear pandemic curve in Croatia in April, and flattened in May. This leads to a conclusion that the earthquake did not have a direct effect on disease spread. Despite the fact that the current pandemic and its responses are unique, this paradox can have interesting repercussions on how we conceptualize and approach notions as vulnerability and resilience.

Bleeding risk assessment in patients undergoing elective cardiac surgery using ROTEM(®) platelet and Multiplate(®) impedance aggregometry.

Impaired platelet function is a major risk factor for peri-operative bleeding and transfusion. This prospective, observational study enrolled 101 consecutive patients undergoing elective cardiac surgery with cardiopulmonary bypass. Platelet function was assessed by two whole blood impedance aggregometers (ROTEM(®) platelet and Multiplate(®) ), using three different activators (arachidonic acid, adenosine diphosphate and thrombin receptor-activating peptide-6), at three peri-operative time points (before anaesthesia, after aortic declamping and 5-10 min after protamine administration). Platelet function was impaired over the time-course in all assays. Results after protamine administration demonstrated the best correlation with postoperative chest tube drainage. Patients with a chest tube drainage exceeding the 75th percentile of the entire study population, during the first 24 postoperative hours, were characterised to have excessive bleeding. Both devices provided similar predictability for postoperative chest tube drainage and red blood cell transfusion requirements. The latter was associated with the degree of platelet inhibition and the number of pathways inhibited determined respective cut-off values.

Significance of clinical stage, extent of surgery and outcome in cutaneous squamous cell carcinoma of the head and neck.

The authors analyzed a new clinical staging system and its correlation with pathologic findings and patient survival. Patients were eligible for inclusion in this longitudinal retrospective cohort study if they had cutaneous squamous cell carcinoma on the head or neck, underwent surgery and had a minimum 3 year follow-up. The primary study variable was using a new clinical staging system. Secondary variables included the parotid as a predictor of metastatic spread to the lymphatic nodes in the neck and primary lesion histopathologic traits. The outcome variable was patient survival. Associations between variables were assessed using Fisher's exact test, Mann-Whitney test, Kaplan-Meier method and Mantel log-rank test. p<0.05 was considered significant. The sample comprised 103 patients. Regional metastatic disease was found in 24 patients. Histopathological analysis showed a higher frequency of neck metastatic disease if the parotid was positive for metastases (p=0.022). An extended staging system showed significant correlation between survival rate and substages (p=0.0105). Perineural invasion was a negative prognostic factor (p=0.0151). The results of this study suggest that combining curative parotidectomy and elective neck dissection could be beneficial in high risk patients. Both neck and parotid metastases should be included in the clinical and histological N classification.
