National Cohort Study of Long-Term Exposure to PM Components and Mortality in Medicare American Older Adults.

There is increasing evidence linking long-term fine particulate matter (PM) exposure to negative health effects. However, the relative influence of each component of PM on health risk is poorly understood. In a cohort study in the contiguous United States between 2000 and 2017, we examined the effect of long-term exposure to PM main components and all-cause mortality in older adults who had to be at least 65 years old and enrolled in Medicare.

Four novel Curtobacterium phages isolated from environmental samples.

Intestinal and non-intestinal nasal cavity adenocarcinoma: Impact of wood dust exposure.

Unlabelled: The aim of the present study was to investigate the role of wood dust exposure in intestinal (ITAC) and non-intestinal type (non-ITAC) nasal adenocarcinoma, so as to improve understanding of the oncogenic mechanisms in the light of the recent literature and of evo-devo concepts.

Materials And Methods: All consecutive patients operated in our institution for nasal adenocarcinoma diagnosed on anatomopathology between May 2004 and February 2014 were included. Surgical specimens were examined twice by independent pathologists, blind to wood dust exposure status.

The quest for a nanoparticle-based vaccine inducing broad protection to influenza viruses.

Influenza virus infections are a significant public threat and the best approach to prevent them is through vaccination. Because of the perpetual changes of circulating influenza strains, the efficacy of influenza vaccines rarely exceeds 50%. To improve the protection efficacy, we have designed a novel vaccine formulation that shows a broad range of protection.

Compartmentalized endoscopic resection of the olfactory cleft for nasal intestinal adenocarcinomas.

Background: The purpose of this study was to describe the pathology of the different compartments in endoscopic resection of nasal intestinal-type adenocarcinomas (ITACs) and its relationships with oncologic outcomes.

Methods: This retrospective study included all patients endoscopically operated for nasal ITACs, followed by radiotherapy in the majority of cases, between 2004 and 2014. The surgery systematically separated 3 compartments: ethmoid lateral mass, olfactory cleft, and anterior cranial fossa (in cases with skull-base invasion) to analyze their pathological "focal" or "massive" invasion by the tumor.

Chronic nasal dysfunction.

Chronic nasal dysfunction is a clinical concept in the diagnostic and therapeutic management of sinonasal diseases, based on the evo-devo theory of formation of the nose according to which the nose is not a single organ but rather an association of three organs: olfactory nose, respiratory nose and paranasal sinuses. In chronic nasal dysfunction theory, etiological diagnosis takes account of the possible pathophysiological independence of nasal symptoms, in accordance with the different origins and physiology of the three organs constituting the nose. The diagnostic approach of the chronic nasal dysfunction concept breaks down the pathology so as to propose treatment(s) adapted to the diseased organ(s) and to the capacity for physiological resolution of dysfunction induced in one organ by pathology in a neighboring nasal organ.

Endoscopic surgery of the olfactory cleft.

The olfactory cleft is the specific site of development of many tumours (respiratory epithelial adenomatoid hamartoma, intestinal-type adenocarcinoma, neuroblastoma, inverted papilloma, glomangiopericytoma, etc.) and is also the site of CSF rhinorrhoea via the cribriform plate (cribri-rhinorrhoea). Olfactory cleft surgery must therefore be considered to be a specific type of surgery, complementary to ethmoidal labyrinth surgery and anterior skull base surgery.

A situational analysis of breast cancer early detection services in Trinidad and Tobago.

Purpose: A situational analysis of breast cancer (BC) early detection services was carried out to investigate whether Trinidad and Tobago (T&T) has the framework for successful organized national screening.

Methods: An online survey was designed to assess the availability, accessibility, quality control and assurance (QC&A), and monitoring and evaluation (M&E) mechanisms for public and private BC early detection. A focus group with local radiologists (n = 3) was held to identify unaddressed challenges and make recommendations for improvement.

Can the Risks of Cerebrospinal Fluid Leak After Vestibular Schwannoma Surgery Be Predicted?

Objective: Identifying predictive factors of cerebrospinal fluid (CSF) leak after translabyrinthine approach (TLA) for vestibular schwannoma.

Design: Retrospective study.

Setting: Tertiary care center.

The data not collected on community forestry.

Conservation and development practitioners increasingly promote community forestry as a way to conserve ecosystem services, consolidate resource rights, and reduce poverty. However, outcomes of community forestry have been mixed; many initiatives failed to achieve intended objectives. There is a rich literature on institutional arrangements of community forestry, but there has been little effort to examine the role of socioeconomic, market, and biophysical factors in shaping both land-cover change dynamics and individual and collective livelihood outcomes.

Olfactory neuroblastoma behavior inside and outside the olfactory cleft.

Purpose: Olfactory neuroblastoma (ONB) is a rare malignant tumor of the nose. The currently available evidence links this disease with cells of the olfactory epithelium. The detailed description of tumor site and its extension is the key of treatment.

[Personality dimensions and neuropsychological performance in first-degree relatives of patients with schizophrenia and by affective psychosis].

Several studies have found a significant increase in the prevalence of some personality disorders in the first-degree relatives of patients with schizophrenia; other studies have found subtle neuropsychological deficits in these relatives. However, little is known about the specificity of the personality traits reported or about the relationship between these traits and the neuropsychological deficits. One hundred first-degree relatives of patients with schizophrenia (AS) and 88 first-degree relatives of affective psychotic (APA) patients completed the Eysenck Personality Questionnaire which measures extraversion, neuroticism, psychoticism.

Value of fetal skeletal radiographs in the diagnosis of fetal death.

The aim of this study was to assess the value of fetal skeletal radiographs in determining the etiology of fetal death. A total of 1193 post-mortem fetal skeletal radiographs were analysed. Fetuses were classified into one of three groups (group I: abnormality diagnosed during pregnancy; group II: maternal pathology; group III: spontaneous abortion of pregnancy, IIIa before 26 weeks of gestation (WG), IIIb after 26 weeks of gestation).

The response of breeding doses to nematodiasis: segregation into "responders" and "non-responders".

Responder and non-responder does were identified from a flock of 95 Scottish cashmere 2-6 year-old does exposed to natural nematode infection over a 12-month period. Every 5 weeks, the does were faecal sampled for worm-egg counts prior to anthelmintic treatment. Responsive and non-responsive individuals were identified on the basis of their cumulative faecal egg count (FEC) rankings: the 8 lowest and 8 highest rankings were deemed to be responders and non-responders, respectively.

Studies on caprine responsiveness to nematodiasis: segregation of male goats into responders and non-responders.

Eighty-three 2-4-year-old intact male goats exposed to a combination of artificial and natural challenge were segregated into responders and non-responders by ranking of weekly faecal egg counts (FECs). Retrospective analysis of samples over a 15-week-period showed responders had a statistically lower mean FEC than non-responders. Estimates of repeatability between consecutive egg counts were significant in both groups.

The role of prolactin in the reactivation of hair follicles in relation to moulting in cashmere goats.

The effects of the suppression or elevation of plasma prolactin concentrations in spring on the timing of the reactivation of the hair follicles and the timing of the spring moult were investigated in cashmere goats. Thirty eight adult female goats, housed under conditions of natural photoperiod at 55 degrees 55'N from mid-December until May, were allocated to four groups starting on 5 January: ten served as untreated controls, eight received 2 mg ovine prolactin subcutaneously every 12 h for 7 weeks (PRL), twelve received 35 mg bromocriptine intramuscularly every 14 days for 17 weeks (BCR) and eight received injections of both ovine prolactin and bromocriptine at the above dose rates for 7 weeks (PRL+BCR). In the PRL group there was an earlier reactivation of the secondary hair follicles (PRL vs control, proportion of secondary follicles in antigen, weeks 1-5, P < 0.

Inheritance of goat coat colors.

Goat color inheritance was evaluated based on color description of 218 kids and their parents (10 sires, 178 dams) from mixed crosses between several goat populations in an experiment on cashmere fiber production. Altogether 10 color patterns were observed. They were postulated to be caused by 10 alleles at the Agouti locus, with the allele for white or tan color being the top dominant allele, and the nine others codominant.

Prevalence of anthelmintic-resistant nematodes in fibre-producing goats in Scotland.

Six cashmere goat herds in Scotland were surveyed to assess the prevalence of anthelmintic resistance and the species of nematode involved. Resistance was determined in vivo by a faecal egg count reduction test and in vitro using an egg hatch assay and specific faecal egg identification techniques. Benzimidazole resistance was present in five of the herds, insufficient eggs were obtained from the other herd to draw firm conclusions.

A comparison of tenoxicam and piroxicam in the treatment of rheumatoid arthritis.

Tenoxicam 20 mg OD was compared with piroxicam 20 mg OD for patients with rheumatoid arthritis (RA). One hundred and two patients from 5 centers were enrolled: 51 in the tenoxicam group and 51 in the piroxicam group. Evaluation of the primary efficacy variables demonstrated no difference in efficacy between treatment groups.
