Summary Background Since December, 2019, Wuhan, China, has experienced an outbreak of coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Epidemiological and clinical characteristics of patients with COVID-19 have been reported but risk factors for mortality and a detailed clinical course of illness, including viral shedding, have not been well described. Methods In this retrospective, multicentre cohort study, we included all adult inpatients (≥18 years old) with laboratory-confirmed COVID-19 from Jinyintan Hospital and Wuhan Pulmonary Hospital (Wuhan, China) who had been discharged or had died by Jan 31, 2020. Demographic, clinical, treatment, and laboratory data, including serial samples for viral RNA detection, were extracted from electronic medical records and compared between survivors and non-survivors. We used univariable and multivariable logistic regression methods to explore the risk factors associated with in-hospital death. Findings 191 patients (135 from Jinyintan Hospital and 56 from Wuhan Pulmonary Hospital) were included in this study, of whom 137 were discharged and 54 died in hospital. 91 (48%) patients had a comorbidity, with hypertension being the most common (58 [30%] patients), followed by diabetes (36 [19%] patients) and coronary heart disease (15 [8%] patients). Multivariable regression showed increasing odds of in-hospital death associated with older age (odds ratio 1·10, 95% CI 1·03–1·17, per year increase; p=0·0043), higher Sequential Organ Failure Assessment (SOFA) score (5·65, 2·61–12·23; p Interpretation The potential risk factors of older age, high SOFA score, and d-dimer greater than 1 μg/mL could help clinicians to identify patients with poor prognosis at an early stage. Prolonged viral shedding provides the rationale for a strategy of isolation of infected patients and optimal antiviral interventions in the future.

Eighty-two localized fibrous tumors of the pleura (LFTP) were reviewed retrospectively for the clinical, pathologic, and radiologic findings. Forty-four women and 38 men ranged in age from 17 to 78 years (mean, 54.7 years). Sixty-four benign LFTP ranged in size from 2 to 30 cm (mean, 13.2 cm), and 18 malignant tumors ranged from 3 to 23 cm (mean, 14.4 cm). Forty-eight patients (60%) presented with symptoms. Radiographs of 76 patients demonstrated solitary masses occupying or extending into the inferior hemithorax (79%). Computed tomography (CT) of 78 lesions demonstrated lobular masses (83%) that formed at least one acute angle (96%) or only acute angles (65%) with the adjacent pleura. Heterogeneous lesion attenuation was documented in 88% of enhanced and in 68% of unenhanced CT scans. Contrast enhancement was common (62% of cases). Magnetic resonance (MR) imaging of 18 lesions demonstrated heterogeneous signal intensity on both T1- and T2-weighted images (78% and 83%, respectively). Multiplanar MR imaging allowed visualization of the diaphragm and documentation of an intrathoracic mass in all cases. LFTP are solitary lobular heterogeneous masses that occur in symptomatic adults and often affect the inferior hemithorax. Malignant lesions are radiologically indistinguishable from those with benign histologic characteristics. Radiographic and CT features characteristic of pleural location are typically absent.

Giant hydatid cysts of the lung (diameter, ≥10 cm) are considered more difficult to treat surgically than are smaller cysts. We reviewed our experience with giant pulmonary hydatid cysts, focusing on clinical symptoms, cystic location, extent of surgery, and postoperative complications, according to age, long-term results, and comparison with non-giant cysts. From January 1988 to January 2008, 537 patients underwent surgery for pulmonary hydatid cysts. We separated patients into 2 groups: patients who had cysts <10 cm (group A) and those who had giant cysts (group B). Group B comprised 75 patients (14%). Giant cysts were more common in younger patients (mean age, 30 vs 32 yr; P=0.014). The most frequent complaints were cough, chest pain, and dyspnea. Patients with giant cysts were more often symptomatic at presentation (96% vs 88%; P=0.04). In both groups, lower-lobe locations predominated. Parenchyma-saving operations were almost uniformly performed for each group; however, a higher percentage of patients in group B required anatomic resection (4% vs 1%; P=0.038). Fifty-seven patients (10%) also underwent resection of concomitant liver cysts. Cystic rupture occurred more frequently in group B than in group A (27% vs 15%; P=0.01). There were no deaths in either group, nor were there significant differences in morbidity between groups.In summary, giant hydatid cysts of the lung occurred more often in younger patients and were more often symptomatic at presentation. Regardless of size, the cysts could usually be surgically treated without lung resection, and size did not appear to influence short-term perioperative outcomes.

Surgical management of pulmonary hydatid cysts: is size an important prognostic indicator?

There is debate about which bronchial closure technique is the best to prevent bronchopleural fistulas (BPFs). We aim to assess the effect of bronchial closure procedures and patients' characteristics on BPF occurrence in pulmonary resections. Bronchial closures in 625 consecutive patients were assessed. Stumps were closed by manual suturing in 204 and by mechanical stapling in 421 cases. In the mechanical stapling group, stapling supported by manual suture was performed in 170 cases. BPFs occurred in 3.8%. Of these, stapling was used in 5.0%, whereas manual suturing was used in 1.5% (P=0.04). BPFs were more prevalent among patients who had undergone pneumonectomy (P<0.01), right pneumonectomy (P<0.01), stapler closure (P<0.01), patients with co-factors (P<0.01), and patients who had undergone preoperative neo-adjuvant (P=0.01) or postoperative adjuvant therapy (P=0.03). There was no difference in the frequency of BPF between patients with and without adjuvant support in the stapling group. The optimum bronchial closure method has to be chosen by considering the patient and bronchus based characteristics. This has to be assessed carefully, especially in pneumonectomy and co-factors. The manual closure seems to be the more preferable method in risky patients. An additive support suture on the bronchial stump does not decrease the risk of BPF.

Bronchial closure methods and risks for bronchopleural fistula in pulmonary resections: how a surgeon may choose the optimum method?

Primary hydatid cysts very rarely form in intrathoracic yet extrapulmonary sites. Accurate preoperative diagnosis in such cases is difficult, and corrective surgical procedures necessarily differ from those that are used to treat the far more typical pulmonary or hepatic hydatid cysts. We retrospectively evaluated the diagnostic and operative characteristics of intrathoracic extrapulmonary hydatid cysts, and we examined the outcome of aggressive surgical interventions that went beyond conventional parenchymal-sparing procedures.

From 2003 through 2007, 14 patients (mean age, 39.14 ± 16.8 yr) underwent surgical treatment in our hospital for primary intrathoracic extrapulmonary hydatid cysts. These cysts were variously in the diaphragm, chest wall, mediastinum, pleura, and pericardial cavity. All patients underwent cystectomy, decortication, resection, and repair of the adjacent structure. No complication, recurrence, or death occurred in the follow-up period of 15 ± 18.1 months (range, 2–52 mo).

In order to achieve complete resection and to avoid recurrence of disease from intrathoracic extrapulmonary hydatid cysts, the thoracic surgeon should forgo cystotomy and capitonnage in favor of cystectomy with a wide resection and reconstruction of surrounding tissues. Postoperatively, patients should adhere to a regimen of anthelmintic therapy.

Primary intrathoracic extrapulmonary hydatid cysts: analysis of 14 patients with a rare clinical entity.

Purpose
It has been suggested that lung cancer follows a more aggressive course and has a poorer prognosis in young patients than in elderly patients We conducted this study to determine whether the basal characteristics and survival of young patients undergoing surgical resection of lung cancer differ from those of elderly patients

Outcome of surgery for lung cancer in young and elderly patients.

Purpose
Social limitations in addition to treatment failure, despite preventive precautions and aggressive medical treatment, are the main indications for surgery in patients with bronchiectasis. The aim of this study was to evaluate all aspects of treatment outcomes in surgically treated patients with bronchiectasis.
