Asthma and incident coronary heart disease: an observational and Mendelian randomisation study.

BACKGROUND: Observational studies suggest asthma is a risk factor for coronary heart disease (CHD) and sex modifies the risk, but they may suffer from methodological limitations. To overcome these, we applied a "triangulation approach", where different methodologies, with different potential biases, were leveraged to enhance confidence in findings. METHODS: First, we conducted an observational study using UK medical records to match asthma patients 1:1, by age, sex and general practitioner (GP) practice, to the general population. We measured the association between asthma and incident CHD (myocardial infarction: hospitalisation/death) by applying minimal sufficient adjustment: model 1, smoking, body mass index, oral corticosteroids, atopy and deprivation; model 2, additionally adjusting for healthcare behaviour (GP consultation frequency). Second, we conducted a Mendelian randomisation (MR) study using data from the UK Biobank, Trans-National Asthma Genetic Consortium (TAGC) and Coronary Artery Disease Genome-wide Replication and Meta-analysis consortium (CARDIoGRAM). Using 64 asthma single nucleotide polymorphisms, the effect of asthma on CHD was estimated with inverse variance-weighted meta-analysis and methods that adjust for pleiotropy. RESULTS: In our observational study (n=1 522 910), we found asthma was associated with 6% increased risk of CHD (model 1: HR 1.06, 95% CI 1.01-1.13); after accounting for healthcare behaviour, we found no association (model 2: HR 0.99, 95% CI 0.94-1.05). Asthma severity did not modify the association, but sex did (females: HR 1.11, 95% CI 1.01-1.21; males: HR 0.91, 95% CI 0.84-0.98). Our MR study (n=589 875) found no association between asthma and CHD (OR 1.01, 95% CI 0.98-1.04) and no modification by sex. CONCLUSIONS: Our findings suggest that asthma is not a risk factor for CHD. Previous studies may have suffered from detection bias or residual confounding.

Trajectories of cardiac troponin in the decades before cardiovascular death: a longitudinal cohort study.

BACKGROUND: High-sensitivity cardiac troponin testing is a promising tool for cardiovascular risk prediction, but whether serial testing can dynamically predict risk is uncertain. We evaluated the trajectory of cardiac troponin I in the years prior to a cardiovascular event in the general population, and determine whether serial measurements could track risk within individuals. METHODS: In the Whitehall II cohort, high-sensitivity cardiac troponin I concentrations were measured on three occasions over a 15-year period. Time trajectories of troponin were constructed in those who died from cardiovascular disease compared to those who survived or died from other causes during follow up and these were externally validated in the HUNT Study. A joint model that adjusts for cardiovascular risk factors was used to estimate risk of cardiovascular death using serial troponin measurements. RESULTS: In 7,293 individuals (mean 58 ± 7 years, 29.4% women) cardiovascular and non-cardiovascular death occurred in 281 (3.9%) and 914 (12.5%) individuals (median follow-up 21.4 years), respectively. Troponin concentrations increased in those dying from cardiovascular disease with a steeper trajectory compared to those surviving or dying from other causes in Whitehall and HUNT (Pinteraction < 0.05 for both). The joint model demonstrated an independent association between temporal evolution of troponin and risk of cardiovascular death (HR per doubling, 1.45, 95% CI,1.33-1.75). CONCLUSIONS: Cardiac troponin I concentrations increased in those dying from cardiovascular disease compared to those surviving or dying from other causes over the preceding decades. Serial cardiac troponin testing in the general population has potential to track future cardiovascular risk.

Step-by-step full factorial design to optimize a quantitative sandwich ELISA.

In this work, a quantitative sandwich ELISA was optimized, through a full factorial design of experiments (DOE) in successive steps of a preliminary protocol obtained by the method of one factor at a time (OFAT). The specificity of the optimized ELISA, the lower limit of quantification, the quantification range and the analytical sensitivity of the antigen quantification curve were evaluated, in comparison with the curve obtained from the preliminary protocol. The full factorial DOE was linked to a simple statistical processing, which facilitates the interpretation of the results in those laboratories where there is no trained statistician. The step-by-step optimization of the ELISA and the successive incorporation into the protocol of the best combination of factors and levels, allowed obtaining a specific immunoassay, with an analytical sensitivity 20 times greater and with a lower limit of antigen quantification that decreased from 156.25 at 9.766 ng/mL. As far as we know, there are no reports of optimization of an ELISA following the step-by-step scheme used in this work. The optimized ELISA will be used for the quantification of the TT-P0 protein, the active principle of a vaccine candidate against sea lice.

Metabolomic Diversity in Microbial Mats Under Different Environmental Conditions: A Tool to Test Microbial Ecosystem Chemical Change.

Microbial mats are microbial communities capable of recycling the essential elements of life and considered to be the oldest evidence of microbial communities on Earth. Due to their uniqueness and limited sampling material, analyzing their metabolomic profile in different seasons or conditions is challenging. In this study, microbial mats from a small pond in the Cuatro Cienegas Basin in Coahuila, Mexico, were collected in wet and dry seasons. In addition to these samples, mesocosm experiments from the wet samples were set. These mats are elastic and rise after heavy rainfall by forming gas domes structures known as "Archean domes", by the outgassing of methanogenic bacteria, archaea, and sulfur bacteria. Extracts from all mats and mesocosms were subjected to untargeted mass spectrometry-based metabolomics and molecular networking analysis. Interestingly, each mat showed high chemical diversity that may be explained by the temporal dynamic processes in which they were sampled.

Starch degradation in the bean fruit pericarp is characterized by an increase in maltose metabolism.

The bean fruit pericarp accumulates a significant amount of starch, which starts to be degraded 20 days after anthesis (DAA) when seed growth becomes exponential. This period is also characterized by the progressive senescence of the fruit pericarp. However, the chloroplasts maintained their integrity, indicating that starch degradation is a compartmentalized process. The process coincided with a transient increase in maltose and sucrose levels, suggesting that ß-amylase is responsible for starch degradation. Starch degradation in the bean fruit pericarp is also characterized by a large increase in starch phosphorylation, as well as in the activities of cytosolic disproportionating enzyme 2 (DPE2, EC 2.4.1.25) and glucan phosphorylase (PHO2, EC 2.4.1.1). This suggests that the rate of starch degradation in the bean fruit pericarp 20 DAA is dependent on the transformation of starch to a better substrate for ß-amylase and the increase in the rate of cytosolic metabolism of maltose.

New Terpenoids from the Corticioid Fungus Punctularia atropurpurascens and their Antimycobacterial Evaluation.

Chemical investigation of Punctularia atropurpurascens strain HM1 (Punctulariaceae), a corticioid isolated from a decorticated piece of Quercus bark collected in Bosque de Tlalpan, Mexico City, led to the isolation of a new drimane, 1-α-hydroxy-isodrimenine (1: ) and a new tetrahydroxy kauranol, 16-hydroxy-phlebia-nor-kauranol (2: ), together with the known N-phenylacetamide (3: ). Structures of all compounds were elucidated by spectroscopic and spectrometric methods, and the absolute configuration of 1: and 2: was confirmed via single-crystal X-ray crystallography. The isolated compounds showed modest antimycobacterial activity.

Genome Mining and Molecular Networking-Based Metabolomics of the Marine Facultative Aspergillus sp. MEXU 27854.

The marine-facultative Aspergillus sp. MEXU 27854, isolated from the Caleta Bay in Acapulco, Guerrero, Mexico, has provided an interesting diversity of secondary metabolites, including a series of rare dioxomorpholines, peptides, and butyrolactones. Here, we report on the genomic data, which consists of 11 contigs (N50~3.95 Mb) with a ~30.75 Mb total length of assembly. Genome annotation resulted in the prediction of 10,822 putative genes. Functional annotation was accomplished by BLAST searching protein sequences with different public databases. Of the predicted genes, 75% were assigned gene ontology terms. From the 67 BGCs identified, ~60% belong to the NRPS and NRPS-like classes. Putative BGCs for the dioxomorpholines and other metabolites were predicted by extensive genome mining. In addition, metabolomic molecular networking analysis allowed the annotation of all isolated compounds and revealed the biosynthetic potential of this fungus. This work represents the first report of whole-genome sequencing and annotation from a marine-facultative fungal strain isolated from Mexico.

Chemical Diversity and Antimicrobial Potential of Cultivable Fungi from Deep-Sea Sediments of the Gulf of Mexico.

A collection of 29 cultivable fungal strains isolated from deep-sea sediments of the Gulf of Mexico were cultivated under the "one strain, many compounds" approach to explore their chemical diversity and antimicrobial potential. From the 87 extracts tested, over 50% showed antimicrobial activity, and the most active ones were those from cultures grown at 4 °C in darkness for 60 days (resembling deep-sea temperature). PCA analysis of the LC-MS data of all the extracts confirmed that culture temperature is the primary factor in the variation of the 4462 metabolite features, accounting for 21.3% of the variation. The bioactivity-guided and conventional chemical studies of selected fungal strains allowed the identification of several active and specialized metabolites. Finally, metabolomics analysis by GNPS molecular networking and manual dereplication revealed the biosynthetic potential of these species to produce interesting chemistry. This work uncovers the chemical and biological study of marine-derived fungal strains from deep-sea sediments of the Gulf of Mexico.

Holistic health risk assessment in an artisanal mercury mining region in Mexico.

Mexico is one of the world's leading mercury producers and exporters. However, mercury mining is carried out using artisanal procedures, which highly impact ecosystems. In the municipality of Pinal de Amoles, Queretaro, Mexico, artisanal mercury mining (AMM) is practiced in a region that has been categorized as a Biosphere Reserve. Therefore, a holistic health risk assessment for mercury was performed in the region, including environmental monitoring (air, water, and soil) and mercury exposure in both humans (children, women, and miners) and biota (plants, rodents, and worms). The atmospheric mercury determination was carried out using the JEROME® J405 analyzer, whereas total mercury in environmental and biological samples was determined by atomic absorption spectrophotometry/cold vapor. Results showed that mercury concentrations in the environmental and biological matrices exceeded their respective reference values. These results demonstrate the direct influence of AMM in the increasing levels of mercury in all the components of the studied ecosystem. Therefore, comprehensive intervention strategies must be implemented to reduce and prevent human health and ecological risks due to the presence of mercury. In this regard, the Minamata Convention for mercury control should include biomonitoring programs not only for humans but also for critical ecological receptors in polluted ecosystems.

Recommendations on the pharmacological treatment of epithelial ovarian cancer in Mexico.

Ovarian cancer is the third most frequent gynaecological malignancy worldwide and in Mexico, with a high mortality rate, due to that in many cases its diagnosis is made in advanced stages. Prognosis is important for determining the subtype and the degree of evolution. During lasts years, the management of ovarian cancer has undergone an important evolution with the incorporation of new therapeutic options, which in turn represent an increase in the survival of these patients. We present recommendations for the management of ovarian cancer developed by an expert panel Mexican based on available evidence so far and the characteristics of health care in the country.

El cáncer de ovario es la tercera neoplasia maligna ginecológica más frecuente globalmente y también en México, con una elevada tasa de mortalidad debido a que en muchos casos su diagnóstico se realiza en etapas avanzadas. Para establecer su pronóstico es importante la determinación del subtipo y del grado de evolución. En los últimos años, el manejo del cáncer de ovario ha sufrido una importante evolución con la incorporación de nuevas opciones terapéuticas, que a su vez representan un incremento en la supervivencia de estas pacientes. Se presentan las recomendaciones para el manejo del cáncer de ovario elaboradas por un panel de expertos mexicanos basadas en la evidencia disponible hasta el momento y en las características de la atención sanitaria del país.

Association of aortic stiffness with cognitive decline: Whitehall II longitudinal cohort study.

Aortic stiffness is associated with an increased risk of cardio- and cerebrovascular disease and mortality and may increase risk of dementia. The aim of the present study is to examine the association between arterial stiffness and cognitive decline in a large prospective cohort study with three repeated cognitive assessment over 7 years of follow-up. Aortic pulse wave velocity (PWV) was measured among 4300 participants (mean ± standard deviation age 65.1 ± 5.2 years) in 2007-2009 and categorized based on the tertiles: (lowest third: < 7.41 m/s), (middle third: 7.41-8.91 m/s), and (highest third: > 8.91 m/s). A global cognitive score was calculated in 2007-2009, 2012-2013, and 2015-2016 based on responses to memory, reasoning and fluency tests. Standardized global cognitive score (mean = 0, SD = 1) in highest third versus lowest third of PWV category was lower at baseline (- 0.12, 95% CI - 0.18, - 0.06). Accelerated 7-year cognitive decline was observed among individuals with the highest PWV [difference in 7-year cognitive change for highest third versus lowest third PWV: - 0.06, 95% CI - 0.11, - 0.01, P < 0.01]. Higher aortic stiffness was associated with faster cognitive decline. Clinicians may be able to use arterial stiffness severity as an indicator to administer prompt treatments to prevent or delay the onset of cognitive decline or dementia. Future studies need to determine whether early intervention of vascular stiffness is effective in delaying these outcomes.

Hypertension care cascade in Chile: a serial cross-sectional study of national health surveys 2003-2010-2017.

BACKGROUND: Trend data on hypertension prevalence and attainment indicators at each step of the care cascade (awareness, treatment, control) are required in Chile. This study aims to quantify trends (2003-2017) in prevalence and in the proportion of individuals with hypertension attaining each step of the care cascade among adults aged 17 years or older, and to assess the impact of lowering the blood pressure (BP) thresholds used to define elevated BP on these indicators. METHODS: We used data from 2003, 2010, and 2017 Chilean national health surveys. Each year we assessed levels of (1) mean systolic (SBP) and diastolic (DBP) blood pressure, (2) hypertension prevalence (BP ≥ 140/90 mmHg or use of antihypertensive treatment), and (3) awareness, treatment, and control. Logistic regression on pooled data was used to assess trends in binary outcomes; linear regression was used to assess trends in continuous SBP and DBP. We compared levels of hypertension prevalence using two sources to ascertain antihypertensive treatment (self-reported versus medicine inventory). The 2017 American College of Cardiology/American Heart Association (ACC/AHA) guidelines were used to re-define hypertension using lower thresholds (BP ≥ 130/80 mmHg). RESULTS: Hypertension prevalence was 34.0, 32.0 and 30.8% in 2003, 2010 and 2017, respectively. Levels of treated- and controlled-hypertension were significantly higher in 2017 than in 2003 (65% versus 41% for treatment, P < 0.001; 34% versus 14% for control, P < 0.001), while levels of awareness were stable (66% versus 59%, P = 0.130). Awareness, treatment, and control levels were higher among females in 2003, 2010, and 2017 (P < 0.001). Mean SBP and DBP decreased over the 15-year period, except for SBP among females on treatment. Adopting the 2017 ACC/AHA guidelines would increase hypertension prevalence by 17 and 55% in absolute and relative terms, respectively. CONCLUSIONS: Chile has experienced a positive population-wide lowering in blood pressure distribution which may be explained partly by a significant rise in levels of treated- and controlled-hypertension since 2003. Lowering the thresholds used to define elevated BP would substantially increase the financial public health challenge of further improving attainment levels at each step of the care cascade. Innovative and collaborative strategies are needed to improve hypertension management, especially among males.

Acute Variceal Bleeding: Does Octreotide Improve Outcomes in Patients with Different Functional Hepatic Reserve?

BACKGROUND: Current guidelines do not differentiate in the utilization of vasoactive drugs in patients with cirrhosis and acute variceal bleeding (AVB) depending on liver disease severity. MATERIAL AND METHODS: In this retrospective study, clinical outcomes in 100 patients receiving octreotide plus endoscopic therapy (ET) and 216 patients with ET alone were compared in terms of failure to control bleeding, in-hospital mortality, and transfusion requirements stratifying the results according to liver disease severity by Child-Pugh (CP) score and MELD. RESULTS: In patients with CP-A or those with MELD < 10 octreotide was not associated with a better outcome compared to ET alone in terms of hospital mortality (CP-A: 0.0 vs. 0.0%; MELD < 10: 0.0 vs. 2.9%, p = 1.00), failure to control bleeding (CP-A: 8.7 vs. 3.7%, p = 0.58; MELD < 10: 5.3 vs. 4.3%, p = 1.00) and need for transfusion (CP-A: 39.1 vs. 61.1%, p = 0.09; MELD < 10: 63.2 vs. 62.9%, p = 1.00). Those with severe liver dysfunction in the octreotide group showed better outcomes compared to the non-octreotide group in terms of hospital mortality (CP-B/C: 3.9 vs. 13.0%, p = 0.04; MELD ≥ 10: 3.9 vs. 13.3%, p = 0.03) and need for transfusion (CP-B/C: 58.4 vs. 71.6%, p = 0.05; MELD ≥ 10: 50.6 vs. 72.7%, p < 0.01). In multivariate analysis, octreotide was independently associated with in-hospital mortality (p = 0.028) and need for transfusion (p = 0.008) only in patients with severe liver dysfunction (CP-B/C or MELD ≥ 10). CONCLUSION: Patients with cirrhosis and AVB categorized as CP-A or MELD < 10 had similar clinical outcomes during hospitalization whether or not they received octreotide.

[Medical genetics services in VenezuelaServiços de genética médica na Venezuela]. / Los servicios de genética médica en Venezuela.

OBJECTIVE: To characterize medical genetics services in Venezuela and describe the distribution of their resources, services, technologies, and professional training. METHODS: A descriptive, documentary study of genetic services was conducted between February and November 2016, involving a review of primary documentary sources and the use of a data collection form in research institutions to obtain information on the availability of human resources, clinical care, and diagnostic services, as well as professional training. Furthermore, the Venezuelan Society of Human Genetics database was used to identify the human resources available in genetics centers. The criterion for inclusion was being an institution with staff trained in genetics. RESULTS: The inclusion criterion was met by four research institutions, seven universities, and four hospitals, all in the public sector. A total of 124 professionals work in these institutions; 56 of them are physicians and 68 are laboratory staff. Of these professionals, 62% are affiliated with research institutions, which offer patient care services, molecular and biochemical diagnostic services, and, more rarely, cytogenetic, prenatal, and forensic testing. Five regions of the country have between two and four physicians specializing in genetics per million inhabitants. Of the laboratory professionals, 96% are located in two regions (Capital and Zuliana); five regions have none. Research institutions have provided training in genetics to 40% of the country's current human resources. CONCLUSIONS: Genetics services show great variability in terms of diagnostic options. They train large numbers of professionals, but access is limited. There is a need for coordinated policies to integrate these services and reduce existing gaps.

OBJETIVO: Caracterizar os serviços de genética médica da Venezuela com a finalidade de conhecer a distribuição dos recursos, prestação de serviços, tecnologias usadas e formação profissional nesta área. MÉTODOS: Uma pesquisa descritiva documental dos serviços de genética médica foi realizada de fevereiro a novembro de 2016. Foi feita uma revisão das fontes documentais primárias nas instituições de pesquisa com o preenchimento de fichas de coleta de dados com informação sobre a disponibilidade de recursos humanos, prestação de serviços de atendimento e diagnóstico e formação profissional. Foi feita também uma revisão do banco de dados da Sociedade Venezuelana de Genética Humana para identificar os recursos humanos nos centros de genética. O critério de inclusão do estudo foi ser uma instituição com recursos humanos formados em genética. RESULTADOS: Os critérios do estudo foram satisfeitos por 4 instituições de pesquisa, 7 universidades e 4 hospitais, todos da rede pública. Foram identificados 124 profissionais trabalhando nestas instituições: 56 médicos e 68 funcionários da área de laboratório. Sessenta e dois por cento dos profissionais pertencem a instituições de pesquisa que prestam serviços de atendimento clínico e diagnóstico molecular e bioquímico e, menos frequentemente, realizam análises citogenéticas, pré-natais e forenses. Cinco regiões do país têm entre 2 e 4 médicos geneticistas por milhão de habitantes. Além disso, 96% dos profissionais de laboratório estão distribuídos em 2 regiões (capital e Zuliana), sendo que não há nenhum profissional em 5 regiões. As instituições de pesquisa formam atualmente 40% dos recursos humanos em genética do país. CONCLUSÕES: Os serviços de genética médica são caracterizados por grande variabilidade nas opções diagnósticas, acesso limitado e grande contribuição para a formação profissional. Fazem-se necessárias políticas coordenadas para integrar e reduzir as lacunas.

Insurance status and disparities in disease presentation, treatment, and outcomes for men with germ cell tumors.

BACKGROUND: People aged 26 to 34 years represent the greatest proportion of the uninsured, and they have the highest incidence of testicular cancers. The aim of this study was to investigate the association between insurance status and cancer outcomes in men diagnosed with germ cell tumors. METHODS: The Surveillance, Epidemiology, and End Results database was used to identify 10,211 men diagnosed with germ cell gonadal neoplasms from 2007 to 2011. Associations between insurance status and characteristics at diagnosis and receipt of treatment were examined with log-binomial regression. The association between insurance status and mortality was assessed with Cox proportional hazards regression. RESULTS: Uninsured patients had an increased risk of metastatic disease at diagnosis (relative risk [RR], 1.26; 95% confidence interval [CI], 1.15-1.38) in comparison with insured patients, as did Medicaid patients (RR, 1.62; 95% CI, 1.51-1.74). Among men with metastatic disease, uninsured and Medicaid patients were more likely to be diagnosed with intermediate/poor-risk disease (RR for uninsured patients, 1.22; 95% CI, 1.04-1.44; RR for Medicaid patients, 1.39; 95% CI, 1.23-1.57) and were less likely to undergo lymph node dissection (RR for uninsured patients, 0.74; 95% CI, 0.57-0.94; RR for Medicaid patients, 0.76; 95% CI, 0.63-0.92) in comparison with insured patients. Men without insurance were more likely to die of their disease (hazard ratio [HR], 1.88; 95% CI, 1.29-2.75) in comparison with insured men, as were those with Medicaid (HR, 1.51; 95% CI, 1.08-2.10). CONCLUSIONS: Patients without insurance and patients with Medicaid have an increased risk of presenting with advanced disease and dying of the disease in comparison with those who have insurance. Future studies should examine whether implementation of the Patient Protection and Affordable Care Act reduces these disparities. Cancer 2016;122:3127-35. © 2016 American Cancer Society.

Risk factors associated with Chagas disease in pregnant women in Santander, a highly endemic Colombian area.

OBJECTIVE: To determine the prevalence and risk factors associated with Chagas disease in pregnant women in an endemic area of Santander, Colombia. METHODS: Cross-sectional study included 23 municipalities of Santander, Colombia. Serological IFAT and ELISA tests were undertaken to detect IgG anti- Trypanosoma cruzi. A questionnaire was conducted for assessing the risk factors of each participant. Newborns were evaluated at birth and followed up to 1 year of age to determine congenital infection. RESULTS: An overall prevalence of 3.2% (95% CI 2.4-4.2) among 1518 pregnant women was detected. Prevalences by provinces were as follows: Guanentina: 6.0% (95% CI 4.1-8.5), García Rovira: 2.9% (95% CI: 1.5-4.8) and Comunera: 0.4% (0.4-2.3). The main risk factors identified were age >32 years old (OR: 2.1; 95% CI: 1.1-3.9); currently having a thatched roof (OR: 11.8; CI95% 2.2-63.2) and a thatched roof during childhood (OR: 3.0; 95% CI: 1.4-6.6); having below primary school education level (OR: 4.6; 95% CI: 2.2-9.5); and a history of a close contact with the vector (triatomine bugs) at least once during their lifetime (OR: 6.9; 95% CI: 3.7-12.9). No congenital cases were detected by parasitological or serological techniques. CONCLUSIONS: Prevalence of Chagas disease in pregnant women is a potential source of infection in this Colombian endemic area. The main risk factors associated with seropositivity were related to conditions favouring the contact with the vector. The results show that it is necessary to continue an active surveillance in order to offer diagnosis and treatment to mothers and their newborns in addition to screening to pregnant women from endemic areas.

Portal vein thrombosis in patients with cirrhosis: just a common finding or a predictor of poor outcome?

 Background & Aims. It is unclear whether portal vein thrombosis (PVT) unrelated to malignancy is associated with reduced survival or it is an epiphenomenon of advanced cirrhosis. The objective of this study was to assess clinical outcome in cirrhotic patients with PVT not associated with malignancy and determine its prevalence. MATERIAL AND METHODS: Retrospective search in one center from June 2011 to December 2014. RESULTS: 169 patients, 55 women and 114 men, median age 54 (19-90) years. Thirteen had PVT (7.6%). None of the patients received anticoagulant treatment. The PVT group was younger (49 [25-62] vs. 55 [19-90] years p = 0.025). Child A patients were more frequent in PVT and Child C in Non-PVT. Median Model for End Stage Liver Disease (MELD) score was lower in PVT (12 [8-21] vs. 19 [7-51] p ≤ 0.001) p ≤ 0.001). There was no difference between upper gastrointestinal bleeding and spontaneous bacterial peritonitis in the groups. Encephalopathy grade 3-4 (4 [30.8%] vs. 73 [46.8%] p = 0,007) and large volume ascites (5 [38.5%] vs. 89 [57.1%] p= 0,012) was more common in non-PVT. Survival was better for PVT (16.5 ± 27.9 vs. 4.13 ± 12.2 months p = 0.005). CONCLUSIONS: We found that PVT itself does not lead to a worse prognosis. The most reliable predictor for clinical outcome remains the MELD score. The presence of PVT could be just an epiphenomenon and not a marker of advanced cirrhosis.

Personal Therapy in Psychiatry Residency Training: A National Survey of Canadian Psychiatry Residents.

OBJECTIVE: The authors collected nationally representative data on Canadian residents' experiences with and perspectives on personal psychotherapy in their psychiatric training. METHODS: A 43-item questionnaire was distributed electronically to all current psychiatry residents in Canada (N = 839). RESULTS: Four hundred residents from every program across Canada returned the survey (response rate 47.7%). The prevalence of personal therapy at any time was 55.3%, with 42.8% receiving personal therapy during residency. Of residents who undertook personal psychotherapy, 59.3% engaged in weekly therapy, 74.1% received psychodynamic psychotherapy, and 81.5% participated in long-term therapy (>1 year). Personal growth, self-understanding, and professional development were the most common reasons for engaging in personal therapy; however, one-third of residents did so to alleviate symptoms of depression, anxiety, or other mental health concerns. Time was the most important factor impeding residents from personal therapy; only 8.8% found stigma to act as a barrier. The vast majority of residents rated their experience with personal therapy as having a positive or very positive impact on their personal life (84.8%) and overall development as psychiatrists (81.8%). For 64% of respondents, personal therapy had an important or very important role in psychiatry residency training. Residents who received personal therapy rated themselves as better able to understand what happens moment by moment during therapy sessions, detect and deal with patients' emotional reactions, and constructively use their personal reactions to patients. CONCLUSION: Interest in personal therapy remains strong among psychiatry trainees in Canada. Residents who engaged in psychotherapy endorsed greater confidence in psychotherapy and rated their psychotherapy skills more favorably than those who had never been in the patient role, supporting the view of personal therapy as an important adjunct to psychotherapy training during residency.

Psychotherapy in Contemporary Psychiatric Practice.

OBJECTIVE: American data suggest a declining trend in the provision of psychotherapy by psychiatrists. Nevertheless, the extent to which such findings generalize to psychiatric practice in other countries is unclear. We surveyed psychiatrists in British Columbia to examine whether the reported decline in psychotherapy provision extends to the landscape of Canadian psychiatric practice. METHOD: A survey was mailed to the entire population of fully licensed psychiatrists registered in British Columbia (n = 623). The survey consisted of 30 items. Descriptive statistics were used to characterize the sample and psychotherapy practice patterns. Associations between variables were evaluated using nonparametric tests. RESULTS: A total of 423 psychiatrists returned the survey, yielding a response rate of 68%. Overall, 80.9% of psychiatrists (n = 342) reported practicing psychotherapy. A decline in the provision of psychotherapy was not observed; in fact, there was an increase in psychotherapy provision among psychiatrists entering practice in the last 10 years. Individual therapy was the predominant format used by psychiatrists. The most common primary theoretical orientation was psychodynamic (29.9%). Regarding actual practice, supportive psychotherapy was practiced most frequently. Professional time constraints were perceived as the most significant barrier to providing psychotherapy. The majority (85%) of clinicians did not view remuneration as a significant barrier to treating patients with psychotherapy. CONCLUSIONS: Our findings challenge the prevailing view that psychotherapy is in decline among psychiatrists. Psychiatrists in British Columbia continue to integrate psychotherapy and pharmacotherapy in clinical practice, thus preserving their unique place in the spectrum of mental health services.

Cutaneous amyloidosis associated with autoimmune hepatitis-primary biliary cirrhosis overlap syndrome.

Cutaneous amyloidosis is a rare disease characterized by the deposition of amyloid in the dermis. It can be primary or secondary, depending on associated diseases. It has been linked to various autoimmune diseases, including primary biliary cirrhosis. We present the case of a patient with an autoimmune hepatitis-primary biliary cirrhosis overlap syndrome with concomitant cutaneous amyloidosis, a very unusual association, and discuss similar cases and possible pathophysiological implications.
