Helicobacter pylori Infection Does Not Impact on Lung Transplant Outcome.

BACKGROUND: Helicobacter pylori (HP) is a spiral, gram-negative, microaerophilic bacterium that colonises the human gastric mucosa and is associated with gastrointestinal and extragastrointestinal disorders. Since no data are yet available on HP infection in lung transplant patients, we evaluated the prevalence and impact of HP infection in a population of such patients. METHODS: Sixty-seven lung transplant patients were enrolled in the study (35 females and 32 males, age 48.4 ± 13.3 years), 54 underwent bilateral and 13 single lung transplant. Serum antibodies against HP and CagA were assayed in all subjects. RESULTS: The prevalence of HP infection in lung transplant patients was similar to that in the general population (49.25% vs. 51.4%), whereas HP-positive patients showed lower CagA positivity (9% vs. 50.2%, p < 0.0001). There was a higher prevalence of HP infection in patients who underwent lung transplant because of pulmonary fibrosis (p = 0.049), and a lower prevalence in COPD patients (p = 0.011). No correlation was found between HP infection in lung transplant patients and graft outcome. No differences in primary graft dysfunction, acute rejection or bronchiolitis obliterans syndrome-free survival were found. However, more patients who required three or more post-transplant re-hospitalisations were observed among HP-positive patients. CONCLUSIONS: The prevalence of HP infection in lung transplant patients was comparable to that of the general population and to that reported in heart and kidney transplant recipients. It did not seem to impact short-, mid- or long-term lung allograft outcome. H. pylori infection did not prove to be clinically relevant in lung transplant patients.

The Impact of the COVID-19 Pandemic and Lockdown on the Outcome of Glioblastoma.

BACKGROUND: Rapid spread of the SARS-CoV-2 pandemic in 2020 led to an indirect effect on non-COVID patients. Since neuro-oncology cases are unique and brain tumors need a specific therapeutic protocol at proper doses and at the right times, the effects of the pandemic on health care services for patients with glioblastomas (GBs) and their impact on overall survival (OS) and quality of life are not yet known. METHODS: We conducted a retrospective study of 142 GB patients who underwent surgery, radiation, and chemotherapy before and after the lockdown period, aiming to determine the differences in access to care, treatment modality, and adjuvant therapies, and how the lockdown changed the prognosis. RESULTS: The number of procedures performed for GB during the pandemic was comparable to that of the prepandemic period, and patients received standard care. There was a significant difference in the volume of lesions measured at diagnosis with a decreased number of "accidental" diagnoses and expression of a reduced use by the patient for a checkup or follow-up examinations. Patients expressed a significantly lower performance index in the lockdown period with longer progression-free survival (PFS) in the face of a comparable mean time to OS. CONCLUSION: Patients treated surgically for GB during the pandemic period had a more pronounced and earlier reduction in performance status than patients treated during the same period the year before. This appears to be primarily due to lower levels of care in the rehabilitation centers and more frequent discontinuation of adjuvant care.

Giant left atrial myxoma causing acute ischemic stroke.

Atrial myxomas are primary cardiac tumors which may cause ischemic stroke. The authors present a case of a 51-year-old man admitted to the emergency department with right-sided hemiplegia and aphasia caused by ischemic stroke. 2D and 3D transesophageal echocardiography showed an atrial myxoma described as a large mass in the left atrium attached to the interatrial septum. In the end, surgical excision of the myxoma was performed 48 h after diagnosis. Nowadays, specific guidelines concerning the correct time for surgical excision of the myxoma are lacking. The authors highlight the utmost role of echocardiography to promptly characterize a cardiac mass and the importance of discuss about the timing of cardiac surgery.

Atrial myxoma is a rare cardiac tumor that is often located in the left atrium of the heart. Patients with myxoma can have no symptoms, or they can present signs of systemic embolization, where fragments of the tumor have been released into the blood stream and are circulating to different areas of the body. Indeed, if a fragment reaches the brain, it can cause a cerebral acute ischemic stroke, which is a sudden loss of blood circulation to an area of the brain, resulting in a loss of neurologic function. Transesophageal echocardiography, an ultrasound test that produces real-time and detailed images of the heart, is a useful tool that allows physicians to diagnose the presence of an atrial myxoma. In this case report, the authors stress the role of echocardiography in diagnosing patients presenting with sudden neurological symptoms, because it can show a potential mass inside the heart. Once identified, the tumor can be removed surgically as soon as possible to avoid further complications, such as a new stroke.

Clinical Efficacy of Adjuvant Radiotherapy for World Health Organization Grade II Intracranial Meningioma.

BACKGROUND: Maximal surgical resection remains the treatment of choice for grade II meningiomas, and for some authors it is sufficient to guarantee a long indolent course even without postsurgical radiotherapy (RT), but there is no consensus on the use of RT in this patient population. METHODS: We retrospectively compared clinical and radiologic outcomes between World Health Organization grade I (group A) and grade II (group B) surgically treated meningiomas, focusing on the role of adjuvant RT. We registered clinical, surgical, and radiologic data to detect differences in survival and functional outcome between the 2 groups. RESULTS: The final cohort consisted of 284 patients for group A and 94 patients for group B. Group B showed a higher risk of developing recurrence independently of the extent of resection (7.75% for Group A vs. 27.7% for Group B, P = 0.01). Patients who did not undergo adjuvant RT documented recurrence in 50% of cases, compared with 19% of patients who underwent RT (P = 0.024). There is a weak difference in the risk of developing postoperative seizures in the group submitted to radiotherapy (P = 0.08). Performance status remained stable for both groups, but for Group B it tended to decrease significantly after 1 year with regard to extent of resection and RT. CONCLUSIONS: Recurrence is more frequent for grade II meningiomas, even though there are no significant differences in terms of complications and functional outcome. Radiotherapy in grade II meningiomas does indeed lead to better control of recurrence but leads to an increased risk of seizures and reduced performance status.

Coronary-specific quantification of myocardial deformation by strain echocardiography may disclose the culprit vessel in patients with non-ST-segment elevation acute coronary syndrome.

Aims: To compare the diagnostic accuracy of speckle tracking echocardiography technique using territorial longitudinal strain (TLS) for the detection of culprit vessel vs. vessel-specific wall motion score index (WMSI) in non-ST-segment elevation-acute coronary syndrome (NSTE-ACS) patients scheduled for invasive coronary angiography (ICA). Methods and results: One hundred and eighty-three patients (mean age: 66 ± 12 years, male: 71%) diagnosed with NSTE-ACS underwent echocardiography evaluation at hospital admission and ICA within 24 h. Culprit vessels were left anterior descending (LAD), left circumflex (CX), and right coronary arteries (RCAs) in 38.5%, 39.6%, and 21.4%, respectively. An increase of affected vessels [1-, 2-, and 3-vessel coronary artery disease (CAD)] was associated with increased WMSI and TLS values. There was a statistically significant difference of both WMSI-LAD, WMSI-CX, WMSI-RCA and TLS-LAD, TLS-CX, TLS-RCA of myocardial segments with underlying severe CAD compared to no CAD (P = 0.001 and P < 0.001, respectively). Moreover, a significant difference of TLS-LAD, TLS-CX, TLS-RCA, and WMSI-CX of myocardial segments with an underlying culprit vessel compared to non-culprit vessels (P < 0.001, P < 0.001, P = 0.022, and P < 0.001, respectively) was identified. WMSI-LAD and WMSI-RCA did not show statistical significant differences. A regression model revealed that the combination of WMSI + TLS was more accurate compared to WMSI alone in detecting the culprit vessel (LAD, P = 0.001; CX, P < 0.001; and RCA, P = 0.019). Conclusion: Territorial longitudinal strain allows an accurate identification of the culprit vessel in NSTE-ACS patients. In addition to WMSI, TLS may be considered as part of routine echocardiography for better clinical assessment in this subset of patients.

Relationship between Salivary Amylase and Xerostomia in Intensity-Modulated Radiation Therapy for Head and Neck Cancer: A Prospective Pilot Study.

PURPOSE: A single-institution prospective pilot study was conducted to the assess correlation between salivary amylase and xerostomia in patients with head and neck squamous cell carcinoma (HNSCC) treated with intensity-modulated radiotherapy (IMRT). METHODS AND MATERIALS: Serum saliva amylase, clinician-reported xerostomia (using Common Terminology Criteria for Adverse Events), and patient-reported xerostomia (using 8-item self-reported xerostomia-specific questionnaire) were prospectively collected at baseline, during treatment and thereafter. Correlations between variables were assessed by correlation matrices. RESULTS: Twelve patients with locally advanced HNSCC formed the cohort. Eighty-three percent were male, 75% were smokers, 100% had clinical positive lymph nodes at diagnosis, and 42% received induction chemotherapy. All patients received IMRT with concurrent cisplatin-based chemotherapy. No grade ≥4 xerostomia was observed. Severe (G3) acute and late xerostomia occurred in five cases (41.7%) and two cases (16.7%), respectively. Patient-reported xerostomia scores were highly correlated with the clinician-reported scores (ρ = 0.73). A significant correlation was recorded between the concentration of amylase and the acute (ρ = -0.70) and late (ρ = -0.80) xerostomia. CONCLUSION: Preliminary results are encouraging. Prospective clinical trials are needed to define the value of salivary amylase in the management of HNSCC tumors.

The INCH Trial - Induction Chemotherapy in Patients With Bulky Anal Canal Cancer: Evaluation of the Pilot Phase.

AIM: To assess feasibility, complications and efficacy of induction chemotherapy followed by standard chemoradiotherapy in patients with bulky anal canal cancer. PATIENTS AND METHODS: Patients with squamous cell carcinoma of the anal canal, staged bulky tumor with or without nodal involvement were prospectively enrolled. Before standard chemoradiotherapy, patients received induction chemotherapy with 3 cycles of 75 mg/m2 cisplatin and 750 mg/m2 5-fluorouracil. Patients were followed-up routinely until recurrence or death. RESULTS: Seven patients with bulky anal canal cancer were evaluable for this pilot phase of the study. All patients had human papillomavirus-negative disease. Five completed the scheduled induction chemotherapy and all patients completed the programmed concomitant chemoradiotherapy. None had severe hematological toxicity. The majority of patients (6/7) had tumor downsizing after induction treatment. Six months after chemoradiotherapy, complete response was documented in three patients and salvage surgery was performed in two cases. With a median follow-up of 38 months (range=28-48 months), two patients are disease-free survivors. CONCLUSION: Induction chemotherapy has the potential to become a standard approach in patients with bulky human papillomavirus-negative anal canal cancer.
