- Aseptic Meningitis Caused by Coxiella BurnetiiPublication . Figueiredo, C; Candeias, F; Brito, MJAcute Q fever can have multiple presentations but neurologic involvement is rare. We describe the case of a 16-year-old female with severe headache and aseptic meningitis with acute Coxiella burnetii infection.

- Lobar Lung Transplantation: A Single-Center 10-Year ExperiencePublication . Cruz, Z; Neri, F; Roxo, M; Figueiredo, C; Moita, C; Costa, AR; Santos Silva, J; Reis, J; Maciel Barbosa, J; Calvinho, P; Semedo, LBackground: The shortage of donors for lung transplants is the main limitation of the preceding. Lobar transplantation is an alternative especially useful in patients with short stature and small thoracic cavities. The aim of this study was to perform a descriptive analysis of Portuguese patients who underwent lobar lung transplantation. Methods: A retrospective study was conducted, and patients submitted to lobar lung transplantation from January 2012 to December 2023 were evaluated. A descriptive analysis was made, including demographic data, lung diseases, waiting list dynamics, pre-transplant evaluations, and post-transplant outcomes. Results: Sixteen lobar transplants were performed with a predominance of female patients and a median age of 47 years. Most patients had interstitial lung disease or bronchiectasis either due to cystic fibrosis or non-cystic fibrosis. The median predicted total lung capacity (pTLC) ratio was 0.73. The median waiting list time was 6 months with 9 urgent transplants and 1 emergent lobar retransplant. Extracorporeal membrane oxygenation (ECMO) was used in pre-, intra-, and postoperative periods. Most transplanted lobes were the median lobe (ML) + right upper lobe (RUL) and left upper lobe (LUL). The median length of stay was 58 days, with complications such as PDG grade 3, bronchial tree ischemia, and concentrical stenosis of bronchial anastomosis. Six patients died in this period, 1 in the immediate postoperative period and 5 during the post-transplant hospitalization, with a median survival of 20.7 months and a 1-year and 5-year survival rate of 60%. Conclusion: Our results show a population with an increased waiting list converging in many urgent cases, with an early mortality and high primary graft dysfunction rate. Nevertheless, mid- and long-term survival are promising.
- Major Pulmonary Surgery in Patients with Compromised Lung FunctionPublication . Gonçalves Pereira, R; Branco, J; Narciso Rocha, F; Figueiredo, C; Costa, AR; Santos Silva, J; Eurico Reis, J; Calvinho, PIntroduction: The risk stratification of lung resection is fundamentally based on the results of pulmonary function tests. In patients considered to be at risk, major surgery is generally denied, opting for potentially less curative therapies. Objective: To evaluate the postoperative outcomes of major lung surgery in a group of patients deemed high risk. Methods: We performed a retrospective review of clinical records of all patients submitted to lobectomy, bilobectomy or pneumonectomy in a 3-year period in a reference Thoracic Surgery Unit. The patients were then divided in two groups: group A composed of patients with normal preoperative pulmonary function and group B which included patients with impaired lung function, defined as FEV1 and/or DLCO ≤60%. Results: A total of 234 patients were included, 181 (77.4%) in group A and 53 (22.6%) in group B. In group B, patients had more smoking habits, were more often associated with chronic obstructive pulmonary disease and were also more frequently submitted to thoracotomy. When surgery was motivated by primary lung cancer this group had a more advanced clinical stage of the disease. In the postoperative period, these patients had longer hospital stay, longer chest drainage time and greater need for oxygen therapy at home, however, no statistically significant difference was noted in morbidity or mortality. Conclusions: Major thoracic surgery can be safely performed in selected patients considered to be high risk for resection by pulmonary function tests. A potentially curative surgery should not be denied based on respiratory function tests alone.
- Thromboembolic Risk in COVID-19 Patients: Is There a Hidden Link?Publication . Cidade, J; Pinheiro, H; Dias, A; Santos, M; Nascimento, B; Figueiredo, C; Pinto, R; Pereira, L; Rodrigues, C; Maltez, FBackground Although evidence has emerged indicating that patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pneumonia present a high risk of venous thromboembolism (VTE), its real incidence and best diagnosis course remain unclear. In this study, we aimed to determine the incidence of pulmonary embolism in these patients and the role of D-dimer serum level as a predictive factor of a new VTE event. Methodology This was a single-center retrospective observational cohort study conducted in a tertiary hospital. All patients admitted to the infectious diseases ward with SARS-CoV-2 pneumonia with clinical or laboratory criteria for suspected VTE events were eligible for inclusion in the study. The t-test or Mann-Whitney U test was used to analyze the differences between the with-VTE group and the without-VTE group. Results Overall, VTE incidence was registered to be 30%. Chest computed tomography angiography data revealed thrombus mainly in segmental (five patients, 71%) and subsegmental pulmonary artery branches (four patients, 57%). No thrombus on major branches was documented. D-dimer serum levels (collected at hospital admission, 48 hours before the suspected VTE event date and at suspected VTE event date) were analyzed, and, despite a consistent tendency of higher values in the with-VTE group, no statistical difference was observed. Moreover, no statistical difference was observed between the two groups in mortality rates. Conclusions A clear higher risk of VTE events in SARS-CoV-2 pneumonia patients was not documented, and a link between the impact of VTE occurrence and a worse prognosis was not demonstrated. Therefore, we suggest that the use of D-dimer serum level should not be used as a predictor of VTE in SARS-CoV-2 pneumonia patients.
