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.

[Pulmonary involvement in the course of cytomegalovirus infection in an immunocompetent adult]. / Atteinte pulmonaire au cours d'une infection à Cytomegalovirus chez un adulte immunocompétent.

INTRODUCTION: Cytomegalovirus (CMV) infection in the immunocompetent is generally silent or it may present as a mononucleosis like syndrome but, rarely, it can lead to symptomatic manifestations. CASE REPORT: An immunocompetent and previously healthy 43- year-old woman presented with fever, dyspnoea, liver cell necrosis and a mononucleosis syndrome. The CT scan showed diffuse ground-glass opacity. BAL and blood cultures were sterile. Urinary antigens (Legionella pneumophila, Streptococcus pneumoniae) and serology for atypical respiratory pathogens (Mycoplasma pneumoniae and Chlamydia sp.) were negative. A diagnosis of CMV pneumonia was established on serology (presence of anti-CMV IgM) and PCR detection of viral DNA in the serum. Without antiviral therapy, there was a favourable clinical outcome 1 week later and 1 month later the CT scan was normal. CONCLUSION: CMV infection can lead, exceptionally. to a hypoxic pneumonia in the immunocompetent host. Antiviral therapy should not be prescribed systematically.

[Nocardia aroensis and lung infection: first case report in Africa ]. / Infection pulmonaire à Nocardia aroensis: première observation en Afrique.

Nocardiosis is a rare disease that is difficult to diagnose. Pulmonary forms are most common in association with a variety of nonspecific symptoms. Up to now isolation of the offending species, i.e., Nocardia aroensis, has been reported only once during the first description in Japan. The purpose of this article is to report the second world case of isolation of the Nocardia aroensis in a 50-year-old immunocompetent African woman.

[Solitary fibrous tumour of the pleura: five cases]. / La tumeur fibreuse solitaire pleurale : à propos de cinq observations.

Solitary fibrous tumours are unusual mesenchymatous tumours, most often found on the pleura. The authors report five cases hospitalised between 1998 and 2003. With the greatest occurrence in the fifth decade, they are often accidentally found but sometimes associated with a paraneoplastic syndrome such as refractory hypoglycaemia. The diagnosis is based on computed tomography and complete surgical resection is the best treatment. Adjuvant therapy is proposed for the histologically aggressive forms. Because of the possibility of local or distant recurrence and malignant transformation, long-term monitoring is strongly recommended.

[Shoulder pain revealing tuberculosis of the humerus]. / Une épaule douloureuse révélant une tuberculose osseuse inhabituelle.

Tuberculous spondylitis is the most common form of musculoskeletal tuberculosis. However, extraspinal manifestations have been described with tuberculosis of the wrist, femur, foot or shoulder, as in the patient presented. Because of an often-indolent clinical presentation, the diagnosis is delayed and antituberculous treatment is not able to prevent serious bone destruction.

[An unusual paraneoplastic manifestation in lung cancer: eosinophilic erythroderma]. / Une manifestation paranéoplasique inhabituelle dans le cancer bronchique: l'érythrodermie hyperéosinophilique.

An 81-year-old man was admitted for generalized weakness, erythrodermia and eosinophilia. His chest CT showed nodules related to lung adenocarcinoma. Chemotherapy induced a tumour response with the disappearance of the erythrodermia and eosinophilia. A tumour relapse indicating the recurrence of the erythrodermia and eosinophilia was confirmed 2 months after completion of the chemotherapy. The outcome was rapidly fatal. The evolution of the symptoms suggests that eosinophilic erythrodermia is a paraneoplastic syndrome. Cutaneous paraneoplastic syndromes are rare but may be associated with lung cancer.

[Erlotinib and nonsmall cell lung cancer with brain metastases: a case study with a complete and prolonged response over 17 months]. / Erlotinib et métastases cérébrales d'un cancer bronchique non à petites cellules : une réponse complète et prolongée de 17 mois.

The prognosis of stage IV nonsmall cell lung cancer, in particular with brain metastases, is extremely poor. The impact of targeted therapy, in particular erlotinib, on patient survival has still not been determined. The authors report the case of a patient diagnosed with nonsmall cell lung cancer with bone and brain metastases. The patient presented a complete cerebral response for 17 months with erlotinib prescribed as a third line therapy.

[Pleuro-pulmonary manifestations disclosing hepatic amoebiasis]. / Manifestations pleuropulmonaires révélatrices de l'amibiase hépatique.

During a mission in ex-Yugoslavia between 2001 and 2004, three French soldiers were sent home because of right pneumopathy, right pleurisy after appendicectomy, haemoptysis and liver haematoma, respectively. They previously were stationed in Africa and/or South America. The initial diagnosis was quickly modified: pleuropulmonary manifestations of amoebic hepatic abscess in two cases, and pleuropulmonary amoebiasis in the last case. The outcome was favourable with standard anti-amoebic treatment. The reports illustrate the possibility of hepatic amoebiasis with local pleuropulmonary manifestations and an exceptional case of pleuropulmonary amoebiasis with hepatobronchial fistula. The authors report this experience because it demonstrates that amoebiasis in European countries remains an often forgotten diagnosis. Although known for a long time in developing countries, amoebiasis in the military or in tourists should be systematically considered.

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.

[Perception of nosocomial risk among healthcare workers at "Hopital Principal" in Dakar, Senegal (survey 2004)]. / Perception du risque nosocomial parmi le personnel hospitalier de l'Hôpital Principal de Dakar.

Nosocomial Infection (NI) is also observed in healthcare facilities in non-Western countries. The purpose of this report is to describe the findings of a survey undertaken to evaluate hygiene procedures implemented at the "Hopital Principal" in Dakar, Senegal and to assess perception and awareness of nosocomial risk among the hospital staff. A total of 264 healthcare workers were interviewed. Mean age was 39 years (range, 18-60) and the sex ratio was 1.3 (150 men/114 women). Sixty (22.7%) had university degrees, 106 (40.2%) had secondary school diplomas, 50 (18.9%) had attended middle school, and 13 (4.9%) had no schooling. Analysis of interview data showed that 56.1% (157/264) defined NI as infection acquired at the hospital but that only 9.8% (n=26) knew that a minimum 48-hour delay was necessary to distinguish nosocomial from community acquired infection. While understanding about NI was correlated with education level, data showed that 1 out of 3 physicians (13/39) failed to give the exact definition. Hand contact was cited as the second route of transmission. Isolation precautions were understood by 22.7% of personnel (60/264). Systematic handwashing was reported by 363% (96/264) but observation demonstrated that it was not performed properly regardless of the category of personnel. Care protocols were understood by 54.6% of persons interviewed (144/264). A hygiene-training course had been attended by 52.2% (n=138). Two thirds of the staff (69.7%: 54/264) was able to identify the hygiene nurse. Ninety-eight health care providers (37.1%) were familiar with the CLIN (Comités de Lutte contre les Infections Nosocomiales).

[Poster presentations]. / La communication affichée.

Posters have become an essential tool for dissemination of study findings at medical meetings. By presenting a quick snapshot, posters can be an effective means of communicating the main findings of the research quickly and of stimulating rewarding exchanges with the people in attendance. Success depends on catching and holding the attention of passing attendees long enough to establish contact and share knowledge and experience. The purpose of this article is to provide a few guidelines and techniques for preparing and presenting effective and clear research posters at scientific meetings.

[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.

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.

[Exogenous lipoid pneumonia associated with pulmonary and hepatic sarcoidosis]. / Pneumopathie lipidique exogène associée à une sarcoïdose systémique avec atteinte hépatique nodulaire.

INTRODUCTION: In a patient with basal alveolar shadowing the diagnosis of exogenous lipoid pneumonia (ELP) requires a past history of chronic ingestion of liquid paraffin and the presence of numerous macrophages containing oil droplets in the bronchial lavage (BL). Additional radiological abnormalities suggest an associated disease, notably infection or cancer, as has been described in the literature. CASE REPORT: We report the case of a 50 year old woman presenting with alveolar shadowing in the left lung associated with ipsilateral mediastinal nodes and a pleural effusion in addition to two hepatic nodules. As the diagnosis of ELP did not explain the radiological features a thoracotomy and liver biopsies were performed. Histological examination of the hepatic, pulmonary and lymph node biopsies excluded cancer and mycobacterial disease and showed a florid granulomatous foreign body reaction associated with pulmonary and hepatic sarcoidosis. After a 3 month course of oral corticosteroids the mediastinal lymphadenopathy, pleural effusion and hepatic nodules resolved. The patient has maintained her recovery without further treatment for 4 years. CONCLUSION: The final diagnosis was ELP and systemic sarcoidosis with nodular hepatic involvement.

[A case of atypical pericarditis]. / Une péricardite atypique.

INTRODUCTION: An acute viral pericarditis may reveal a congenital pericardial abnormality. CASE HISTORY: We report the case of a young man of 29 years in whom the development of rapidly progressive dyspnoea and fever led to the echocardiographic diagnosis of a pericardial tumour. The thoracic CT scan showed a mass arising in the superior mediastinum with no evidence of spread. Surgical exploration allowed the excision of a soft mutilobular mass adherent only to the aorta. Histological examination revealed an intrapericardial bronchogenic cyst. CONCLUSION: After a review of bronchogenic cysts we point out the properties of this rare intra-pericardial localisation, one of which is the frequently observed secretion of CA 19-9.

[Positron emission tomography in the diagnosis and follow up of non-small cell lung cancer]. / 18F-FDG-TEP : sa place dans le diagnostic et la surveillance du cancer bronchique non à petites cellules.

In the space of a few years 18F-FDG PET scanning has acquired a place in the management of all stages of the clinical care of patients with lung cancer. Its contributions are being more and more precisely understood during the assessment of mediastinal and metastatic extension and it carries the hope of better therapeutic management and surveillance.

[Using PubMed subject headings to enhance reference searches]. / Utiliser les descripteurs dans PubMed pour améliorer une recherche bibliographique.

The PubMed search engine is an essential tool to stay abreast of the latest medical literature on specific topics. While the basic search techniques are common knowledge, the ability to use medical subject headings properly is an essential in obtaining valuable references. The purpose of this article is to explain what medical subject headings are and how they can be used to improve the results of reference searches in PubMed.

[Lung cancer in Senegal]. / Le cancer bronchique au Sénégal.

In Africa the incidence of lung cancer is rising rapidly. The purpose of this prospective study was to analyze clinical, therapeutic, and prognostic features of lung cancer patients treated at the Principal Hospital in Dakar between 2002 and 2007. A total of 72 cases were compiled over the 5-year study period. In 88% of cases the patient was a male smoker with a mean age of 59.2 years. Histological samples were obtained in 79.1% of cases by bronchial fibroscopy (n=33), CT-guided transthoracic needle biopsy (n=17), or from a metastatic site (n=7). The histological diagnosis was squamous cell carcinoma in 23 cases, adenocarcinoma in 14, large-cell carcinoma in 17, small-cell lung cancer in 2, and bronchiolo-alveolar cancer in 1. Tumor staging demonstrated grades I-II in 6 cases, grade II in 17, and grade IV in 49. Symptomatic management was performed in 68% of patients. In the remaining cases management consisted of chemotherapy in 22 cases, radiotherapy for pain relief in 5, and surgery in 1. Ten patients were lost from follow-up. Median survival was 7 or 3 months depending on whether or not chemotherapy was performed. The much higher rate of histological diagnosis than in the sub-region is due mainly to the availability of trained personnel with access to bronchial endoscopy and CT-scan needle biopsy since September 2003. Administration of cytotoxins is feasible but the cost is excessive due to the lack of universal health care coverage: two-thirds of cases were abandoned whereas chemotherapy significantly improved median survival by 4 months (p < 0.0001). Prognosis of the disease is poor because management is undertaken at an advanced stage. Lung cancer is a health issue in Dakar, Senegal. It is urgent to develop therapeutic standards adapted to the African socio-economic setting as well as an anti-tobacco prevention policy.

[Malignant pleural mesothelioma: interrogations and hopes concerning the expected epidemic]. / Le mésothéliome pleural malin: incertitudes et espoirs face à une épidémie annoncée.

Malignant pleural mesothelioma (MPM) is a rare incurable tumor. Interest in MPM has increased in recent years due to a steadily increasing incidence subsequent to the intensive use of asbestosis, the main causal agent, but also due to better awareness in the political and scientific communities faced with a serious public health issue. Our knowledge of MPM has improved regularly in terms of pathologic diagnosis and the mechanisms underlying the mesothelial carcinogenesis. MPM is also the subject of many technological innovations as illustrated by the recent identification of new biological markers, access to metabolic imaging, and clinical research on targeted treatments. Proper management implies the participation of the general population since the implementation of administrative procedures for social indemnities. In 2007, a more aggressive therapeutic approach is becoming common practice with the use of radiotherapy and the emergence of the concept of multimodal care centered on wide pleuropneumonectomy. These advances create real hope for improvement, but also many interrogations since no standard treatment protocol has been clearly identified.
