Protocols and practices in psilocybin assisted psychotherapy for depression: A systematic review.

BACKGROUND: Psilocybin-assisted psychotherapy (PAP) is a promising treatment option for depression, with randomized controlled trials (RCTs) providing preliminary support for its safety and efficacy. However, there is a lack of consistency across existing treatment protocols and psychotherapeutic approaches. The objective of this review is to summarize and compare current psychotherapy methods of PAP in treating depression and distress in life-threatening illnesses. We sought to comprehensively summarize published psychotherapy protocols from clinical trials to provide insights for future practices. METHODS: A systematic search of four databases (Embase, MEDLINE, PsycINFO, CINAHL) for data relating to psychotherapy protocols was conducted by two independent reviewers. RESULTS: In total, our search identified 1869 articles; after removing duplicates, we screened 1107 articles. We included 70 articles in the full-text review and determined that 28 were eligible for the final review. All protocols include sessions before (preparatory) and after (integration) the psychedelic dosing session with supportive monitoring. However, there was substantial variability and inconsistencies in all other aspects of therapy protocols (e.g., duration and number of sessions, model of therapy). Additionally, significant limitations were identified in the frequent need for more clarity in the description of therapeutic approaches. CONCLUSION: In published clinical trials, PAP has consisted of preparation, supportive dosing, and integration sessions. Beyond this basic framework, significant heterogeneity and lack of clarity were identified in reported psychotherapy protocols, meaning a validated and universally agreed upon protocol for PAP currently does not exist. Future studies should more clearly define and report psychotherapeutic components to identify the safest and most efficacious approaches to PAP.

Evaluation of pneumococcal urinary antigen testing for respiratory tract infection investigations.

OBJECTIVE: The pneumococcal urinary antigen test enables rapid bacteriological diagnosis in respiratory tract infections. The objective was to identify factors associated with a positive pneumococcal urinary antigen test result. PATIENTS AND METHODS: This seven-year retrospective monocentric study was performed on consecutive patients presenting with respiratory tract infections reported as pneumococcal-positive. Epidemiological, biological, and radiological factors were analyzed, and severity scores were calculated. RESULTS: A total of 223 patients were included. Significant associations were observed between positive test results and age over 65years (P=0.01), positive test results and immunosuppression factors (blood disease [25% Ag+ group vs. 4% Ag- group, P=0.001], immunosuppressive therapy [10% Ag+ group vs. 0% Ag- group, P=0.02]). Clinically, fever (64% Ag+ group vs. 42% Ag- group, P=0.01) and cough (46% Ag+ group vs. 19% Ag- group, P<0.01) were associated with a positive result, as were radiological alveolar opacities (67% Ag+ group vs. 44% Ag- group, P=0.01). High PSI score was associated with the Ag+ group (79% vs. 56% Ag- group, P=0.001). CONCLUSION: Age, immunosuppressive factors, typical pneumococcal symptoms, and PSI scores were associated with a positive pneumococcal urinary antigen result.

USTUR Special Session Roundtable-US Transuranium and Uranium Registries (USTUR): A Five-decade Follow-up of Plutonium and Uranium Workers.

The US Transuranium and Uranium Registries is a human tissue program that collects tissues posthumously from former nuclear workers and radiochemically analyzes them for actinides such as plutonium, americium, and uranium. It was established in 1968 with the goal of advancing science and improving the safety of future workers. Roundtable participants recalled various aspects of this multidisciplinary research program, from establishing consistent autopsy protocols to comparing the registries' findings to those of other programs, such as the historical beagle dog studies and the Russian Radiobiological Human Tissue Repository. The importance of meeting ethical and legal requirements, including written consent forms, was emphasized, as was the need to know whether workers were exposed to nonradiological hazards such as beryllium or asbestos. At Rocky Flats, a bioassay program was established to follow workers after they terminated employment. The resulting data continue to help researchers to improve the biokinetic models that are used to estimate intakes and radiation doses. After 50 y, the US Transuranium and Uranium Registries continues to contribute to our understanding of actinides in humans, which is a testament to the vision of its founders, the generosity of its tissue donors, and the many dedicated scientists who have worked together to achieve a common goal.

Weight Trends in Veterans With and Without Diabetes, 2000 to 2014.

OBJECTIVE: The aim of this study was to assess weight trends and diabetes prevalence among US veterans. METHODS: Information from the Veterans Affairs Informatics and Computing Infrastructure Corporate Data Warehouse was used to construct data sets that included demographic data, diabetes status, and weight observations for males and females. Secular and longitudinal trends in mean weight were analyzed. RESULTS: A total of 4,527,865 patients born from 1915 to 1984 with weight data during 2000 to 2014 were included; 36.8% had diabetes. Mean weight at baseline was higher in men and women with diabetes (97 kg and 88 kg, respectively) than in men and women without diabetes (86 kg and 76 kg, respectively). Mean weight increased from 2000 to 2014 (P < 0.001) at rates of 0.36 kg/y in women without diabetes, 0.28 kg/y in men with diabetes, 0.25 kg/y in men without diabetes, and 0.22 kg/y in women with diabetes. Weight decreased in those born before 1940, was stable in those born between 1940 and 1949, and increased in those born since 1950. CONCLUSIONS: Among contemporary veterans, women without diabetes are gaining weight more rapidly than women with diabetes or men. Younger veterans are gaining weight more rapidly than older veterans. Further efforts are needed to prevent weight gain in veterans, especially among women.

[Disseminated nocardiosis caused by Nocardia nova with brain abscesses and osteomyelitis in an immunocompetent patient]. / Nocardiose disséminée à Nocardia nova avec abcès cérébraux et ostéomyélite chez un patient immunocompétent.

INTRODUCTION: Nocardia is an opportunist bacteria involved in patients with cellular immunodepression or chronic lung disease. The most frequent portals of entry are the respiratory tract by inhalation or direct inoculation through a cutaneous effraction. Nocardiosis may be localised or disseminated. CASE REPORT: We report a rare case of disseminated nocardiosis to Nocardia nova with pulmonary, cutaneous, cerebral attacks and femoral osteomyelitis. The diagnosis was confirmed by prolonged cultures of the bronchoalveolar fluid and the pus extracted from a cutaneous lesion. The outcome was favorable under adapted and prolonged antibiotherapy with imipenem and amikacine and then cotrimoxazole. CONCLUSION: This observation is original because it involves a immunocompetent patient with an association of two exceptional locations for N. nova: brain abscesses and femoral osteomyelitis. Screening for cerebral involvement should be systematic, even in the lack of neurological signs. An adapted and prolonged antibiotherapy must be conducted.

Mathematics, anxiety, and the brain.

Given that achievement in learning mathematics at school correlates with work and social achievements, it is important to understand the cognitive processes underlying abilities to learn mathematics efficiently as well as reasons underlying the occurrence of mathematics anxiety (i.e. feelings of tension and fear upon facing mathematical problems or numbers) among certain individuals. Over the last two decades, many studies have shown that learning mathematical and numerical concepts relies on many cognitive processes, including working memory, spatial skills, and linguistic abilities. In this review, we discuss the relationship between mathematical learning and cognitive processes as well as the neural substrates underlying successful mathematical learning and problem solving. More importantly, we also discuss the relationship between these cognitive processes, mathematics anxiety, and mathematics learning disabilities (dyscalculia). Our review shows that mathematical cognition relies on a complex brain network, and dysfunction to different segments of this network leads to varying manifestations of mathematical learning disabilities.

[Mycobacterial pulmonary infection due to Mycobacterium simiae]. / Mycobactériose pulmonaire à Mycobacterium simiae.

INTRODUCTION: Mycobacterium simiae pulmonary infections remain exceptional in France. CASE REPORT: We report a case of M. simiae lung infection and a 10-year follow-up in a non-immunocompromised host. CONCLUSION: This case emphasizes the difficulties of choosing the appropriate drugs and their side effects in the absence of any existing gold standard.

Efficacy of phase 1 trials in malignant pleural mesothelioma: description of a series of patients at a single institution.

BACKGROUND: Malignant pleural mesothelioma (MPM) is a locally aggressive disease with a poor prognosis. After failure of first line platinum-based chemotherapy, there is no widely approved salvage regimen. New strategies for treatment are needed and phase 1 trials appear as a rationale alternative. MATERIALS AND METHODS: MPM patients were enrolled in 20 different phase 1 trials between March 2005 and January 2012, and their data analyzed retrospectively. The primary endpoint was response rate and secondary endpoints were toxicity profile, overall survival (OS) and progression free survival (PFS). OS and PFS were estimated using Kaplan-Meier and their association with baseline characteristics was investigated through a log-rank test. The drugs described were divided into 5 groups based on their mechanism of action. RESULTS: Forty-five patients were analyzed with a median follow up of 20.5 months. The best tumor response was as follows: 4% of patients had a RECIST partial response, 60% had stable disease, 24% had progressive disease and 11% were not evaluable. Grade ≥3 toxicities were observed in 19 (42%) patients. Median OS and PFS were estimated to 6 months (95% CI=[4.2-10.5]) and 2 months (95% CI=[1.3-2.7]), respectively. The cellular motility inhibitors group appeared as the most promising class to be developed in a phase 2 setting. CONCLUSION: Including MPM patients in phase I trials beyond first line of treatment can result in modest clinical benefits with an acceptable toxicity profile. Several molecular pathways involved in MPM have been identified and further novel biologic therapies need to be tested.

[Imported hepatic amebiasis in adults: retrospective study of 58 cases]. / Amœbose hépatique importée de l'adulte : étude rétrospective de cinquante-huit observations.

The authors report the results of a retrospective study of patients hospitalized for serologically- confirmed hepatic amebiasis confirmed by serology in four French military hospitals from January 1, 2002, through December 31, 2012. The study included 58 patients (53 men, 5 women) with a median age of 41 years (range: 25-80). Among them, 34 (59%) were in the military, 10 (17%) were tourists, 10 migrants (15%), and 4 expatriates (5%). For 75%, contamination occurred in sub-Saharan Africa. The qualitative latex test was simple to use and reliable, even in the emergency department. Medical treatment by metronidazole alone was efficacious in 75% of the patients. Indications for drainage must be discussed according to the clinical and laboratory evidence.

[Evaluation of preoperative non-invasive ventilation in thoracic surgery for lung cancer: the preOVNI study GFPC 12-01]. / Évaluation de la ventilation non invasive préopératoire avant chirurgie de résection pulmonaire. Étude préOVNI GFPC 12-01.

BACKGROUND: Surgical resection is the best treatment for stage I and II non-small cell lung cancer. Despite an improvement in the perioperative management of cancer patients and specialization of surgical teams, morbidity and mortality remains significant. Non-invasive ventilation (NIV) is an effective therapeutic option in hypercapnic respiratory failure. It also improves functional and gasometric parameters when undertaken before surgery. The objective of the preOVNI study is to demonstrate that preoperative non-invasive ventilation for 7 days, at home, reduces the postoperative respiratory and cardiovascular complications of lung resection surgery, in a high-risk population. METHODS: A prospective, randomized, controlled open-labelled multicentric French study, under the supervision of the Groupe Français de Pneumocancérologie (GFPC), comparing 7 days of preoperative non-invasive ventilation with standard treatment. Inclusion criteria are: patients suitable for lobectomy or segmentectomy for primary bronchial carcinoma and presenting with obstructive or restrictive lung disease, obesity or chronic cardiac insufficiency. The primary criterion is a composite one, including all respiratory and cardiac complications. The number of patients is 150 in each treatment arm, 300 in total. EXPECTED RESULTS: We think that preoperative NIV will be able to reduce the rate of postoperative complications. If this objective is achieved, the management of these patients could be changed.

[Polymyalgia rheumatica revealing a lung cancer]. / Une pseudopolyarthrite rhizomélique paranéoplasique révélant un cancer bronchique.

Polymyalgia rheumatica is an inflammatory condition belonging to the connective tissue diseases, which occurs quite frequently in the elderly. Previously, cases have been reported in association with malignant tumours, in a synchronous fashion or prior to the appearance of the cancer. In these cases, the polymyalgia rheumatica is considered to be a paraneoplastic syndrome. We report the cases of a 63-year-old woman and a 58-year-old man with severe proximal girdle pain associated to a high-level of systemic inflammatory markers and a diagnosis of polymyalgia rheumatica was made. In the face of a lack of ineffectiveness of analgesic and anti-inflammatory treatments, an intensive investigation was undertaken which in both cases revealed an adenocarcinoma of the lung. The rheumatic manifestations responded well to chemotherapy targeting the lung tumour. We present here a review of the literature to give prominence to the diagnostic pitfalls that can occur around paraneoplastic polymyalgia rheumatica. The presence of therapeutic resistance at the onset of treatment and other atypical features may suggest the presence of an occult malignancy.

[Bifocal lung cancer: the same histology?]. / Cancer bronchique bifocal: une même histologie?

Whereas synchronous lung cancer is rare, synchronous small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) are exceptional. The authors report the case of a 61-year-old man with synchronous unilateral adenocarcinoma and small cell lung cancer, raising the question as to the need for the histology of all of the lesions in the same lobe or same lung as well as the treatment. The medical history, biology, CT and (18)F-FDG TEP-CT did not support a diagnosis of synchronous lung cancer. The prognosis was poor and only surgery could improve the prognosis. This is a rare case and illustrates the difficulty in the diagnosis of multiple lung cancer and the difficulty in treating synchronous lung cancer with different histologies (SCLC and NSCLC).

[Pleuropulmonary manifestations of necrotising vasculitis]. / Manifestations pleuropulmonaires des vascularites nécrosantes.

The pleuropulmonary manifestations of necrotising vasculitis are frequent and polymorphic. If the existence of extrapulmonary signs and the presence of neutrophil polynuclear anticytoplasmic antibodies are helpful for the diagnosis of a bout of vasculitis, the existence of pleuropulmonary symptoms can also make for discussion of infections or iatrogenic effects induced by immunosuppressive treatments.

[Impact of positron emission tomography on clinical management of potentially resectable non-small-cell lung cancer: a French prospective multicenter study]. / Impact de la tomographie par émission de positons au 18-FDG dans la prise en charge des patients porteurs d'un cancer bronchique non à petites cellules a priori opérable. Etude prospective multicentrique française.

BACKGROUND: Whole-body (18)F-deoxyglucose positron emission tomography (FDG-PET) has the potential to improve the management of non-small-cell lung cancer (NSCLC). We prospectively evaluated the impact of combining FDG-PET with conventional staging methods, including computed tomography (CT), on the staging and management of patients with potentially resectable NSCLC. METHODS: Ninety-four consecutive patients with newly diagnosed/suspected NSCLC were enrolled. Each patient was first staged by using conventional methods, and then by FDG-PET. FDG-PET results were forwarded in a sealed envelope and divulged at the weekly staff meeting on staging and treatment, only after "Decision 1", based on conventional staging, had been reached by consensus; reevaluation taking FDG-PET into account yielded "Decision 2". The validity of these latter decisions was analyzed retrospectively. RESULTS: Eighty-nine patients were eligible. Relative to standard imaging, FDG-PET led to clinical staging changes in 26 (29.2%) patients. The stage was lowered in eight cases (9%) and raised in 18 cases (20.2%). "Decision 2" differed from "Decision 1" in 19 patients, modifying the surgical procedure in four cases, indicating other investigations to confirm FDG-PET evidence of metastases in 12 cases, or modifying the medical treatment in three cases. These modifications were retrospectively justified in 9/19 cases, and consisted of 2/4 modifications of the surgical procedure (one hilar and one adrenal metastasis not confirmed histologically), 4/12 further investigations (axillary and liver biopsies, mediastinoscopy, occult colon cancer) and three indications for palliative treatment, in patients who all died within 3 months after FDG-PET. CONCLUSIONS: Based on FDG-PET, management was modified in 19/89 (21.3%) patients, but these changes were justified in only 9/89 patients (10.1%). FDG-PET can detect asymptomatic local and distant metastases and improves the preoperative assessment of NSCLC, thereby avoiding unnecessary surgery. However, histological verification is required because of the risk of false-positive results.

[Pulmonary vein leiomyosarcoma extending into the left atrium]. / Léiomyosarcome de la veine pulmonaire avec extension dans l'oreillette gauche.

In this paper, the authors report the case of a 28-year-old man with pulmonary vein leiomyosarcoma presenting subacute respiratory distress. Thoracic computed tomography and transoesophagal ultrasonographic examination of the heart suggested the diagnosis of a heart tumour revealed by the obstruction of the mitral valve and pulmonary oedema. Emergency cardiac surgery revealed the mass to be a leiomyosarcoma, probably extending from the right inferior pulmonary vein and extending into the left atrium. The clinical evolution was complicated because of a sudden local relapse. The patient underwent a second cardiac intervention involving lower right lobectomy followed by adjuvant chemotherapy with an ifosfamide-adriamycin combination. This treatment failed to control the disease and a third cardiac intervention was necessary with second-line gemcitabine-paclitaxel adjuvant chemotherapy. Further recurrences were observed with metastases first in the scalp and then in the spine and adrenal glands leading to the death of the patient 2 years after the diagnosis.
