Physical and stressful psychological impacts of prolonged personal protective equipment use during the COVID-19 pandemic: A cross-sectional survey study.

BACKGROUND: Healthcare workers (HCWs) caring for COVID-19 infected patients are exposed to stressful and traumatic events with potential for severe and sustained adverse mental and physical health consequences. Our aim was to assess the magnitude of physical and mental health outcomes of HCWs due to the prolonged use of personal protective equipment (PPE) treating COVID-19 patients. METHODS: This cross-sectional study assessed the symptoms of stress, anxiety, insomnia, and psychological resilience using the Stress and Anxiety to Viral Epidemics (SAVE) scale, Insomnia Severity Index (ISI), and Resilience Scale (RS), respectively, in Italy between 1st February and 31st March 2022. The physical outcomes reported included vertigo, dyspnea, nausea, micturition desire, retroauricular pain, thirst, discomfort at work, physical fatigue, and thermal stress. The relationships between prolonged PPE use and psychological outcomes and physical discomforts were analyzed using Generalized Linear Models (GLMs). We calculated the factor mean scores and a binary outcome to measure study outcomes. FINDINGS: We found that 23% of the respondents reported stress related symptoms, 33% anxiety, 43% moderate to severe insomnia, and 67% reported moderate to very low resilience. The GLMs suggested that older people (>55 years old) are less likely to suffer from stress compared to younger people (<35 y.o); conversely, HCW aged more than 35 years are more inclined to suffer from insomnia than younger people (<35 y.o). Female HCW reported a lower probability of resilience than males. University employed HCWs were less likely to report anxiety than those who worked in a community hospital. The odds of suffering from insomnia for social workers was significantly higher than for other HCWs. Female HCW>3 years old, enrolled in training programs for nursing, social work, technical training and other healthcare professionals increased the probability of reported physical discomforts. HCW that worked on non COVID-19 wards and used PPE for low-medium exposure level, were at lower risks for lasting physical side effects as compared to the HCW who worked in high-risk PPE intense, COVID-19 environments. INTERPRETATION: The study suggests that frontline HCWs who had extensive PPE exposure while directly engaged in the diagnosis, treatment, and care for patients with COVID-19 are at significant risks for lasting physical and psychological harm and distress.

Surgery and perioperative management for post-intubation tracheoesophageal fistula: case series analysis.

BACKGROUND: Post-intubation tracheoesophageal fistula (PITEF) is an often mistreated, severe condition. This case series reviewed for both the choice and timing of surgical technique and outcome PITEF patients. METHODS: This case series reviewed ten consecutive patients who had undergone esophageal defect repair and airway resection/reconstruction between 2000 and 2014. All cases were examined for patients: general condition, medical history, preparation to surgery, diagnostic work-up, timing of surgery and procedure, fistula size and site, ventilation type, nutrition, post-operative course and complications. RESULTS: All patients were treated according to Grillo's technique. Overall, 6/10 patients had undergone a preliminary period of medical preparation. Additionally, 3 patients had already had a tracheostomy, one had had a gastrostomy and 4 had both. One patient had a Dumon stent with enlargement of the fistula. Concomitant tracheal stenosis had been found in 7 patients. The mean length of the fistulas was 20.5 mm (median 17.5 mm; range, 8-45 mm), at a median distance from the glottis of 43 mm (range, 20-68 mm). Tracheal resection was performed in all ten cases. The fistula was included in the resection in 6 patients, while it was excluded in the remaining 4 due to their distance. Post-repair tracheotomy was performed in 3 patients. The procedure was performed in 2 ventilated patients. Morbidity related to fistula and anastomosis was recorded in 3 patients (30%), with one postoperative death (10%); T-Tube placement was necessary in 3 patients, with 2/3 decannulations after long-stenting. Definitive PITEF closure was obtained for all patients. At 5-year follow-up, the 9 surviving patients had no fistula-related morbidity. CONCLUSIONS: Primary esophageal closure with tracheal resection/reconstruction seemed to be effective treatment both short and long-term. Systemic conditions, mechanical ventilation, detailed preoperative assessment and appropriate preparation were associated with outcome. Indeed, the 3 patients who had received T-Tube recovered from anastomotic complications.

Prognostic factors in a multicentre study of 247 atypical pulmonary carcinoids.

OBJECTIVES: To analyse clinical and biomolecular prognostic factors associated with the surgical approach and the outcome of 247 patients affected by primary atypical carcinoids (ACs) of the lung in a multi-institutional experience. METHODS: We retrospectively evaluated clinical data and pathological tissue samples collected from 247 patients of 10 Thoracic Surgery Units from different geographical areas of our country. All patients were divided into four groups according to surgical procedure: sub-lobar resections (SURG1), lobar resections (SURG2), tracheobronchoplastic procedures (SURG3) and pneumonectomies (SURG4). Overall survival analysis was performed using the Kaplan-Meier method and log-rank test. Survival was calculated from the date of surgery to the last date of follow-up or death. The parameters evaluated included age, gender, smoking habits, laterality, type of surgery, 7th edition of TNM staging, mitosis Ki-67 (MIB1), multifocal forms, tumourlets, type of lymphadenectomy and neo/adjuvant therapy. For multivariate analysis, a Cox regression model was used with a forward stepwise selection of covariates. RESULTS: Two hundred and forty-seven patients (124 females and 123 males; range 10-84, median 60 years) underwent surgical resection for AC in the last 30 years as follows: n = 38 patients in SURG1, 181 in SURG2, 15 in SURG3 and 14 in SURG4. A smoking history was present in 136 of 247 (55%) patients. The median follow-up period was 98.7 (range 11.2-369.9) months. The overall survival probability analysis of the AC was 86.7% at 5 years, 72.4% at 10 years, 64.4% at 15 years and 58.1% at 20 years. Neuroendocrine multicentric forms were detected in 12 of 247 patients (4.8%; 1 of 12 pts) during the follow-up (range 11.2-200.4, median 98.7 months) and 33.4% had recurrence of disease. There were no significant differences between gender, tumour location and type of surgery at the multivariate analysis. Age [P < 0.001, hazard ratio (HR) 0.60; confidence interval (CI) 0.32-1.12], smoking habits (P = 0.002; HR 0.43, 95% CI 0.23-0.80) and lymph nodal metastatic involvement (P = 0.008; HR 0.46, 95% CI 0.26-0.82) were all significant at multivariate analysis. CONCLUSIONS: ACs of the lung are malignant neuroendocrine tumours with a worst outcome in patients over 70 years and in smokers. With the exception of pneumonectomy, the extent of resection does not seem to affect survival and should be accompanied preferably by lymphadenectomy. Pathological staging, along with a mitotic index more than Ki-67 (MIB1), appears to be the most significant prognostic factor at the univariate analysis.

Tumorlets, multicentric carcinoids, lymph-nodal metastases, and long-term behavior in bronchial carcinoids.

BACKGROUND: The clinical significance of lymph-node metastases, multicentric forms, and tumorlets in bronchial carcinoids is still a matter of debate. Aim of this study was to analyze their prevalence and clinical significance in a series of 123 bronchial carcinoids. PATIENTS AND METHODS: Nodal dissection and serial sections of resected lung parenchima for research of multicentric forms and tumorlets were performed in most patients. Survival curve was produced using the Kaplan-Meyer method and multivariate analysis by the Cox proportional hazard model. RESULTS: Lymph-node involvement was present in 14% of typical (14 of 100) and 13.04% of atypical carcinoids (3 of 23). Multicentric forms (syncronous carcinoids or tumorlets) were found in 11.3% of the total with a negative impact on survival (p = 0.021). Multiple tumorlets were found in 7.3% of all cases at the standard pathologic examination, but whenever accurate palpation and serial sections of the surgical specimen were performed, the percentage reached 24% of the cases. Overall survival was 98.2%, 95.8%, and 83.9% for typical and 71.6%, 57.3%, and 24% for atypical carcinoid respectively at 5, 10, and 15 years. Time from surgery was significantly directly correlated with recurrences (p < 0.0001) and disease related death (p = 0.0002). CONCLUSIONS: A high prevalence of tumorlets, multiple carcinoids, and lymph-nodal involvement was found in our series. On the basis of these observations bronchial carcinoids always require major surgical procedures with systematic nodal dissection, and a careful search for multifocal lesions should always be performed. Follow-up should always be accurate and protracted, due to the frequency of very long-term relapses (often more than 10 years after surgery).

Shock induced by spontaneous rupture of a giant thymoma.

Spontaneous bleeding of thymoma is a very rare event. We report the case of a 73-year-old woman who was referred to our hospital for acute onset of chest pain followed by shock. Chest computed tomographic scanning showed a huge mediastinal tumor with abundant left pleural effusion and contralateral shift of the mediastinum. Emergency surgical treatment was carried out through a clamshell incision. At the opening of the left pleura 1,600 mL of fresh blood was found, originating from a rupture of the tumor's capsular veins. The lesion was completely resected, en-bloc with a wide pericardial excision. The postoperative course was uneventful. The pathology report classified the lesion as thymoma AB.

Surgical treatment of neuroendocrine tumors of the lung.

OBJECTIVE: This report reviews the pattern of neuroendocrine (NE) differentiation, lymph-node involvement, extension of surgery, and survival in 125 NE lung tumor patients. METHODS: Standard diagnostic workup included CT scan, bronchoscopy, bronchial biopsy or Fine Needle Aspiration Biopsy, (111)In-pentetreotide scan (OctreoScan) and mediastinoscopy in selected patients. NE differentiation was assessed based on the morphology and immunohistochemical reactivity for pan-neuroendocrine markers NSE, CGA, and Synaptophysin. For small cell carcinoma (SCC), only clinical stage I and II patients underwent surgery. Several different surgical procedures were utilized, from limited resections to lobectomy, pneumonectomy, and bronchoplastic procedures. Survival was assessed using Kaplan-Meyer method at 5 years. RESULTS: There were 79 typical carcinoid (TC), eight atypical carcinoid (AC), 18 large cell carcinoma (LCC) and 20 SCC patients. Mean age at diagnosis was 54.6+/-15.2 (ranges from 16 to 77 years) for TC, 68.5+/-9.1 (range 53-81) for AC, 68.7+/-4.6 (range 58-77) for LCC, 64.6+/-7.9 (range 48-82) for SCC. Male/female ratio was 1/1 for TC and AC, 2.6/1 for LCC and 9/1 for SCC. Lymph-node involvement was present in 14% of TC, 0% of AC, 31.5% of LCC, and 45% of SCC. Cancer specific survival was 96% for TC, 87.5% for AC, 37.5% for LCC, and 30% for SCC at 5 years from surgery. Presenting symptoms were invariably of respiratory-related. None had the carcinoid syndrome. History of tobacco abuse ranged from 46% for TC to 100% in SCC. Survival ranged from a minimum of 1 month for SCC to a maximum of 168 months with no evidence of disease for TC. Synchronous multicentric forms were found in 14% of TC. Twenty-one percent (4/19) of the patients with SCC treated by induction therapy and surgery, and in few cases by surgery and adjuvant chemotherapy are alive without the evidence of the disease for 5 years. CONCLUSIONS: Due to the high percentage of lymph-node involvement and multicentric forms found in our series lobectomy with radical lymph-node dissection appears, in our opinion, the most appropriate surgical treatment in well-differentiated forms, while more limited resection appears sub-optimal. Also, due to the finding of recurrences many years after surgery, the follow-up must be accurate and protracted in this subgroup. Only Small Cell Lung Carcinoma patients in clinical stage I and II underwent surgery with good long-term results.

Successful endoscopic Nd-YAG laser treatment of endobronchial endometriosis.

Catamenial hemoptysis is a rare condition that is associated with the presence of intrapulmonary or endobronchial endometrial tissue. Diagnosis of and therapy for this condition are still a matter of debate. We describe a case of endobronchial endometriosis with catamenial hemoptysis. An endobronchial lesion was diagnosed by spiral CT scan, taken at the onset of the menses, and confirmed with flexible bronchoscopy. The patient was successfully treated with endoscopic Nd-YAG laser therapy with a 1-day in-hospital procedure. We suggest that endoscopic laser treatment should be the first line of therapy for central airway endometriosis, provided that the source of bleeding has been conclusively located and all of the lesions can be reached with the bronchoscope.

[Prevalence of the neuroendocrine phenotype in thymus neoplasms]. / Prevalenza del fenotipo neuroendocrino nelle neoplasie del timo.

To determine the prevalence of neuroendocrine differentiation in human thymic neoplasms, which are unusual tumours that may range from well-differentiated to overtly malignant, poorly differentiated lesions, an immunohistochemical study was conducted in 23 thymic neoplasms re-classified on the basis of the new 1999 WHO classification. Immunohistochemical evidence of neuroendocrine differentiation in the form of reactivity to the markers synaptophysin, neuron-specific enolase and chromogranin A was found in 6 of 23 tissues (26%). Two of 3 patients with thymic carcinoids (or well-differentiated thymic neuroendocrine carcinoma) were affected by multiple endocrine neoplasia type 1 (MEN-1). Myasthenia gravis was present in 2/6 patients with neuroendocrine differentiation. This study demonstrates the high prevalence of neuroendocrine markers in human thymic neoplasms. Whether and in what percentage of cases immunohistochemical reactivity may be correlated with clinical behaviour and outcome remains a controversial issue. Finally, the association between thymic carcinoids and MEN-1 is a strong indication for clinical and possibly genetic screening of all patients presenting this feature, just as all MEN-1 patients have to undergo thoracic imaging and prophylactic thymectomy in selected cases.
