Can herd seroprevalence be used as an indicator of enzootic stability for bovine anaplasmosis? Insights from a case-control field study in Brazil. Res Vet Sci 2024; 171:105232. [PMID: 38513459 DOI: 10.1016/j.rvsc.2024.105232] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2024] [Revised: 02/23/2024] [Accepted: 03/17/2024] [Indexed: 03/23/2024]
Abstract
Bovine anaplasmosis presents a significant challenge to livestock production in tropical, subtropical, and temperate regions. For many years, the concept of enzootic stability/instability (initially established for babesiosis) and herd seroprevalence as an indicator of outbreak risks have been applied to anaplasmosis. However, this model has never been definitively validated for Anaplasma marginale. The objective of this study was to examine the relationship between herd immunity (seroprevalence) and the occurrence of anaplasmosis outbreaks in Southern Brazil. A case-control study was conducted, categorizing farms into two groups: cases (farms with a history of clinical anaplasmosis) and controls (those without anaplasmosis). Thirteen farms were identified as "cases", while 23 were identified as "controls". A substantial difference in seroprevalence distribution between the two groups was observed. The majority of "control" farms exhibited over 75% of animals with antibodies to A. marginale in both calves and heifers, whereas the majority of "case" farms had a seropositive cattle percentage below 75%. Additionally, twelve months after cattle serology tests, we conducted a prospective follow-up survey to identify any clinical cases of anaplasmosis. Statistical associations (P < 0.05) were found between both retrospective and prospective anaplasmosis outbreaks and the hypothetical threshold of herd seroprevalence (75%). We hypothesize that herd seroprevalence may be an indicator of the risk of occurrence of clinical anaplasmosis. It appears that the epidemiology of cattle anaplasmosis, at least in our conditions, aligns with the well-known model of enzootic stability/instability originally applied to bovine babesiosis.

Identifying the unmet supportive care needs of individuals affected by testicular cancer: a systematic review. J Cancer Surviv 2024; 18:263-287. [PMID: 35781623 PMCID: PMC10960773 DOI: 10.1007/s11764-022-01219-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2022] [Accepted: 05/19/2022] [Indexed: 10/17/2022]
Abstract
PURPOSE To critically appraise studies to identify experiences of unmet supportive care needs of individuals affected by testicular cancer. METHODS A registered priori systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. CINAHL, PsycINFO, and MEDLINE were searched for quantitative, qualitative, and mixed methods studies using a wide range of search terms. All articles were double screened according to a pre-determined eligibility criterion. Reference lists of the final included studies were checked for further eligible studies. The review process was managed using Covidence systematic review software. Data from the studies were extracted, methodological quality appraisal conducted, and a narrative synthesis conducted. RESULTS Of the 72 papers identified, 36 studies were included. In descending order of frequency of need, psychological needs were identified in 26/36, physical needs 18/36, interpersonal/intimacy needs 19/36, health system/information needs 11/36, cognitive needs 9/36, social needs 7/36, and of equal frequencies counts of 4/36 for family, practical, and patient-clinician information needs. Only one study explored spiritual needs and no daily living needs were identified. CONCLUSIONS The experience of needs varied in terms of frequency and distress which were commonly influenced by the age of the individual across the cancer care continuum persisting after 1-year post-treatment. IMPLICATIONS FOR CANCER SURVIVORS When caring for individuals affected by testicular cancer, clinicians are encouraged to take a holistic lens to cancer care, particularly to explore issue or concerns that young men affected by testicular cancer might be embarrassed or reticent to discuss.

Improved adherence to hip fracture standards reduces mortality after hip fractures. Surgeon 2024; 22:25-30. [PMID: 37517981 DOI: 10.1016/j.surge.2023.06.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Revised: 02/11/2023] [Accepted: 06/25/2023] [Indexed: 08/01/2023]
Abstract
BACKGROUND Hip fractures are increasing in incidence due to increasing life expectancy. Mortality continues to improve but it is important to explore which factors are responsible for driving improvements. METHODS A cohort of hip fracture patients predating SARS-CoV-2 was examined to determine the predictors of adherence to the six Irish Hip Fracture Standards (IHFS) and the impact of adherence on short (30 day) and long term (1 year) mortality. Our primary aim was assess the impact of a single HFS and cumulative number of HFS on mortality after hip fracture. Our secondary aim was to determine the impact of the HFS which are intrinsically linked to specialist Geriatric care. RESULTS Across 962 patients, over 5 years, the factors which were associated with adherence to HFS were female gender, increasing ASA grade and being nursed on an orthopaedic ward. Patients with increasing ASA were more likely to have met HFS 4-6 (Geriatrician review HFS4, bone health HFS5 & specialist falls assessment HFS6), less likely to have surgery within 48 h are more likely to develop a pressure ulcer. If the patient was not nursed on an orthopaedic ward all HFS were less likely to be met. At 30 days HFS 4-6 were associated with a statistically significant odds ratio (OR) of being alive, while at one year HFS 1 (admitted to an orthopaedic ward within 4 h), 5 and 6 were associated with a statistically significant OR of being alive. As increasing numbers of hip fracture standards were met patients were more likely to be alive at 30 days and one year. CONCLUSION This study has identified that improved adherence to hip fracture standards are associated with improved mortality at 30 days and one year.

Comparison of Seroprevalence and Identification of Risk Factors for Theileria equi in Horses From Vector-Free and Infested Areas in Southern Brazil. J Equine Vet Sci 2023; 126:104241. [PMID: 36773853 DOI: 10.1016/j.jevs.2023.104241] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Revised: 12/20/2022] [Accepted: 02/06/2023] [Indexed: 02/12/2023]
Abstract
The apicomplexan hemoprotozoan Theileria equi is a tick-borne pathogen that causes disease in equids, and together with Babesia caballi, causes equine piroplasmosis (EP). Many ticks are associated with EP around the world, and in South America three species may be related: Dermacentor nitens, Amblyomma sculptum, and Rhipicephalus microplus, as they are commonly found in horses. Among the species cited above, only R. microplus is found in Rio Grande do Sul state, Southern Brazil. In addition, this state has the only area legally free of R. microplus in Brazil. This study aimed to compare the seroprevalence for T. equi on farms located in a tick-free area (23 farms, 215 horses) and a tick-infested (25 farms, 141 horses) adjacent areas, as well as to identify potential risk factors for exposure to T. equi. Blood was collected from 356 horses from both areas, and later an indirect enzyme-linked immunosorbent assay was performed to detect anti-T. equi antibodies. Besides the blood collection, questionnaires and interviews were conducted in an attempt to identify potential risk factors. The R. microplus-free zone had 6% seropositive horses against 70% in the tick-infested zone. Previous observation of ticks on horses of the herd increased four times the odds of a horse to be seropositive for T. equi, and by three times if ticks were observed on cattle which share paddocks with horses on the farm. The results showed a large difference in T. equi seroprevalence between tick-infested and free areas, and also emphasized the relevance of R. microplus in the epidemiology of T. equi. The study also reveals the potential of the establishment of a T. equi-free zone for horse breeding in Southern Brazil.

Abstract
Abstract
Background
To date, little research has been carried out exploring the burden experienced by informal caregivers of People with Dementia (PwD). We explored factors that influence the burden experienced by caregivers of PwD over 12 months.
Methods
Fifty-two PwD and their informal caregivers were recruited by convenience sampling to the “CHESS” Study. Data were collected at five time points over 12 months between April 2017 and November 2019. Mixed model analyses were used to investigate associations of caregiver burden (measured by the Zarit-Burden Interview; ZBI) with factors in four domains: 1) Psychological Well-Being (PWB; measures of anxiety, depression, and caregiver distress); 2) Social Capital and Resources (SCR; incorporating access to community-based health services, transportation needs, education level, occupation and living situation of the PwD, and employment status of the caregiver); 3) Physical Fitness and Health (PFH; including the Quantitative Timed Up and Go (QTUG), baseline grip strength, indices of frailty, sensory acuity); and Managing Everyday life with Dementia (MED; incorporating measures of cognition, behavioural disturbances, functional ability, and indices of dependence of PwD.
Results
Across all domains, caregiver burden significantly increased over time (p<0.001) and less burden was experienced by caregivers of older PwD (p<0.05). In PWB, higher caregiver depression levels predicted higher levels of caregiver burden (p=0.033). In the SCR domain, caregivers of PwD who were independent in their transport needs experienced lower levels of burden (p=0.002). No other factors within the PFH or MED domains reached significance in predicting caregiver burden.
Conclusion
This longitudinal analysis elucidates potential predictors of caregiver burden and highlights the need for future research to be carried out in this area. In particular, psychological well-being in caregivers was shown to significantly impact on the experience of burden. Interventions to alleviate caregiver burden should be tailored to include support for psychological well-being.

Abstract
Abstract
Background
Approximately, 350-400 patients are admitted to a level 4 hospital for hip-fractures yearly (2019). According to the Irish Hip Fracture Database (2020) the average age for a hip-fracture is 81 years old. Patients post-hip fractures are commenced on Zoledronic acid; a bisphosphonate which is given intravenously 10 days post-surgery and then annually in year two and three. Zoledronic acid is a first line choice of bisphosphonate for the ≥65 population with a fragility fracture.
Methods
274 patients were transferred from the level 4 Hospital waiting list to a level 2 hospital waiting list to streamline the service. Meetings occurred to establish a pathway for the transition of services. A rapid improvement of the level 2 Day Hospital (DH) was commenced. Essential resources, training and information leaflets were developed in order to begin the service. A policy review, procedure guidelines and referral pathway were implemented. An excel database of patient information was transferred between organisations. The 274 patients were triaged by the DH. Pre-assessment phone calls were conducted determining if patients were still eligible for Zoledronic acid.
Results
Of the 274 referrals; 24 had died; 30 refused; 37 were on other bone treatments and another 7 patients haven’t made creatinine clearance, leaving 176. All 176 patients were allocated an appointment for 2022. Of the 176 patients; currently 57 patients have received their Zoledronic acid infusion in the DH. 69 of these referrals had an indicative date for their next Zoledronic acid infusion for dates after April 2022. There are 50 patients yet to receive their treatment which is overdue.
Conclusion
With the prospect of service demands increasing due to Irelands aging population inevitably placing extra pressures on infusion suites in a level 4 hospital. The level 2 hospital has effectively managed to focus on tackling the backlog, streamlining referrals to the bone health service and thus reducing the risk of subsequent hip fractures.

Abstract
Abstract
Background
Research is needed to examine how Quality of Life (QoL) changes as dementia progresses. We explored QoL trajectories over a 12-month period and examined factors that influence QoL in People with Dementia (PwD).
Methods
Fifty-two PwD and their informal caregivers participated in the “CHESS” Study. Data were collected at five time points over 12 months between April 2017 and November 2019. Mixed-model analyses were used to investigate associations of self-rated QoL and caregiver-rated QoL (measured by the DEMQoL and DEMQoL Proxy, respectively) with factors in four domains: 1) Psychological Well-Being (PWB; measures of anxiety and depression); 2) Social Capital and Resources (SCR; incorporating access to community-based health services, education level, occupation and living situation of the PwD, employment status of the caregiver); 3) Physical Fitness and Health (PFH; including the Quantitative Timed Up and Go (QTUG), baseline grip strength, indices of frailty, sensory acuity); and Managing Everyday life with Dementia (MED; incorporating measures of cognition, behavioural disturbances, functional ability, indices of dependence of PwD).
Results
Across all domains, caregivers’ ratings of QoL for PwD decreased over time (p=0.012). In PWB, greater levels of depression (p=0.007) and anxiety in the PwD (p<0.001) predicted lower self-rated QoL, and higher caregiver anxiety levels predicted lower caregiver-rated QoL (p=0.012). In PFH, having a caregiver administer medication (p=0.03) was associated with higher self-rated QoL. Interestingly, caregiver-rated QoL was higher for PwD who took longer to return to sitting during the QTUG (p=0.043). In MED, being independently mobile (p=0.012) predicted higher self-rated QoL. No other factors within the SCR domain reached significance in predicting QoL.
Conclusion
This longitudinal analysis elucidates potential predictors of QoL in PwD. Psychological well-being in PwD and their caregivers was shown to significantly impact on QoL, and so, these factors should be routinely included in future research studies and clinical assessments.

Abstract
Abstract
Background
The prevalence of dementia is increasing worldwide, and innovative strategies are required to meet increasing demands on health services. The Connected HEalth Sustaining home Stay in Dementia (CHESS) Study aimed to provide support to People with Dementia (PwD) and their caregivers in their homes. We aimed to quantitatively assess the acceptance of smart connected health technology by caregivers of PwD through use of standardised questionnaires.
Methods
Fifty-two PwD and their informal caregivers were recruited by convenience sampling to the intervention arm of the CHESS Study. An additional 25 dyads acted as control participants. Questionnaire data were collected following completion of the CHESS study from 27 informal caregivers from the CHESS Technology group and 16 informal caregivers from the Control group. Measures of health technology acceptability included the System Usability Scale (SUS), the eHealth Literacy Scale (eHEALS), the Technology Readiness Index 2.0 (TRI), and the Unified Theory of Acceptance and Use of Technology Scale (UTAUT). Univariate analyses of variance were used to explore differences between groups.
Results
Internal consistency (Cronbach’s alpha) was high for all measures (range 0.68 – 0.96). The SUS score for the technology group was high (M=70.07, SD=17.69), indicating that the CHESS technology had a high level of usability. All participants had a high level of eHealth literacy (M=33.61, SD=10.51). Both groups performed similarly on the TRI and UTAUT, however the control group indicated greater discomfort with health technology and felt less secure in providing their personal information electronically to healthcare professionals than the technology group.
Conclusion
Caregivers across the technology and control groups had high levels of eHealth literacy and found health technology to be generally acceptable. The CHESS technology in particular was rated as highly usable on the SUS by those who used it. These findings offer support for a Connected Health model of care.

Abstract
Abstract
Background
Frailty is highly prevalent in older hip fracture patients, conferring greater risk of poorer outcomes including increased Length of Stay (LOS), Nursing Home (NH) placement and mortality
Methods
This prospective observational study took place in a large university hospital with a daily trauma list and an established orthogeriatric service. We compared 3 different screening tools; Rockwood Clinical Frailty Scale (CFS), Zuckerman’s Functional Recovery Score (FRS) and New Mobility Score (NMS) and their ability to predict outcomes in hip fracture patients. Participants included all hip fracture patients (>/= 60 years old) admitted to the orthopaedic ward from 2016-2018. Scores were assigned by an ortho-geriatrician and were analysed at admission and at 1 year.
Results
Increasing frailty scores were associated with increased mortality, LOS and NH admission rates. Those with a CFS of 4-6 had an increased risk of mortality compared to those with a CFS of 1-3 (OR:3.81, CI 2.15-6.76). Those with a CFS of 7-9 demonstrated increased risk of mortality compared to those without frailty (OR: 8.75, CI 4.58-16.72). Patients with mild-moderate frailty (CFS 4-6) were 5 times more likely to require NH at 1-year (OR 5.09, CI 3.03-8.56) and those with severe frailty (CFS 7-9) were 7 times more likely to be in a NH at 1-year (OR 7.03, CI 3.82-12.94). The moderate frailty group had an inpatient stay 16 days longer than the non-frail group and the severe frailty group, 26 days longer than the non-frail group. Results were similar for FRS and NMS and when adjusted for age. Comparing the discrimination of the different measures for predicting survival, analysis of receiver operating characteristic curves revealed - 0.73 (CFS), 0.72 (NMS) 0.74 (FRS). Interestingly, the mortality rate for men was 32% compared to 21% for females (OR: 1.75 p=0.005).
Conclusion
Assessing frailty with a standardised protocol could reliably estimate the risk of adverse outcomes in hip fracture patients.

Abstract
Abstract
Background
Caregivers of People with Dementia (PwD) can experience high levels of distress, which can negatively affect their physical and psychological well-being. We explored factors that influence Health-Related Quality of Life (HRQoL) of caregivers of PwD over 12 months.
Methods
Fifty-two PwD and their informal caregivers were recruited by convenience sampling to the “CHESS” Study. Data were collected at five time points over 12 months between April 2017 and November 2019. Mixed model analyses were used to investigate associations of caregiver HRQoL (measured by the EuroQol Visual Analogue Scale; EQVAS) with factors in four domains: 1) Psychological Well-Being (PWB; measures of anxiety, depression, and caregiver distress); 2) Social Capital and Resources (SCR; incorporating access to community-based health services, transportation needs, education level, occupation and living situation of the PwD, and employment status of the caregiver); 3) Physical Fitness and Health (PFH; including the Quantitative Timed Up and Go (QTUG), baseline grip strength, indices of frailty, sensory acuity); and Managing Everyday life with Dementia (MED; incorporating measures of cognition, behavioural disturbances, functional ability, and indices of dependence of PwD.
Results
In the PWB domain, greater levels of caregiver depression (p<0.001) and a greater change over time in caregiver distress related to PwD behavioural disturbances (p=0.008) predicted lower caregiver HRQoL. In the PFH domain, HRQoL was lower for caregivers of PwD who were frail (p=0.04) and had severe comorbidities (p=0.037). None of the factors within the SCR or MED domains reached significance.
Conclusion
This longitudinal analysis elucidates potential predictors of HRQoL in caregivers of PwD. In particular, caregiver depression and distress related to behavioural disturbances in PwD were shown to significantly impact on HRQoL ratings. Caregiver interventions should be tailored to include support for psychological well-being.

Abstract
Introduction Of those with schizophrenia, one third develop treatment-resistant illness. Nearly 60% of these benefit from clozapine- the only antipsychotic medication licensed in this group. Objectives As treatment-resistant illness developed in the follow-up of a first-episode psychosis (FEP) cohort, clozapine was prescribed. This study retrospectively compared the clozapine prescribing patterns, within this cohort, to National Institute for Health and Care Excellence (NICE) guidelines. In addition, impact on hospitalisation, physical health monitoring and augmentation strategies employed following clozapine initiation were examined. Factors delaying initiation of clozapine treatment or contributing to its discontinuation were also explored. Methods The study included 339 individuals resident within an Irish community mental health team catchment area, referred with FEP from 1 January 2005 to 31 August 2016. Data were extracted from electronic medical records. Results Within the cohort, clozapine was prescribed to 32 individuals (9.4%). The mean number of adequate trials of antipsychotic prior to starting clozapine was 2.74 (SD 1.13; range 1–5). The mean time to clozapine trial was 2.1 years (SD 1.95; range 0.17–6.25). Following initiation of clozapine, mean hospital admissions per year fell from 2.3 to 0.3 (p=0.00). Mean inpatient days pre- and post-clozapine also decreased (147 vs. 53; p=0.00). In all, 18 patients ceased use of clozapine, 5 temporarily and 13 permanently. Conclusions Patients are being prescribed clozapine earlier than previously demonstrated. However, delayed treatment remains common, and many patients discontinue clozapine. Further research is necessary to describe and address factors which contribute to its discontinuation. Disclosure No significant relationships.

Detection of Rickettsia spp. and Bartonella spp. in Ctenocephalides felis fleas from free-ranging crab-eating foxes (Cerdocyon thous). MEDICAL AND VETERINARY ENTOMOLOGY 2019; 33:536-540. [PMID: 30848844 DOI: 10.1111/mve.12371] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/12/2018] [Revised: 01/08/2019] [Accepted: 01/29/2019] [Indexed: 06/09/2023]
Abstract
Fleas are insects with a worldwide distribution that have been implicated in the transmission of several pathogens. The present study aimed to investigate the presence of Rickettsia spp. (Rickettsiales: Rickettsiaceae) and Bartonella spp. (Rhizobiales: Bartonellaceae) in fleas from free-ranging crab-eating foxes Cerdocyon thous (Linnaeus, 1766) (Carnivora: Canidae) from Rio Grande do Sul, southern Brazil. Fleas were collected manually from animals and used for the molecular detection of Rickettsia spp. and Bartonella spp. Twenty-nine C. thous were sampled in six municipalities. Four foxes were parasitized by 10 fleas, all of which were identified as Ctenocephalides felis (Bouché, 1935) (Siphonaptera: Pulicidae). DNA from Rickettsia felis Bouyer et al., 2001 and Rickettsia asembonensis Maina et al., 2016 were found in three and eight fleas, respectively. In four fleas, DNA of Bartonella sp. was identified. Phylogenetic analysis grouped Bartonella sp. together with other genotypes previously reported in C. felis worldwide. The scenario described in the present study highlights a Neotropical canid parasitized by the invasive cosmopolitan cat flea, which in turn, is carrying potentially invasive vector-borne microorganisms. These findings suggest that C. felis is adapted to wild hosts in wilderness areas in southern Brazil, hypothetically exposing the Neotropical fauna to unknown ecological and health disturbances.

Abstract
Spotted fever (SF) is a tick-borne disease associated with Rickettsia spp.. In the Pampa biome, Southern Brazil, cases of SF seem to be strongly linked with the practice of hunting wild animals. An investigation of rickettsiae in tick species found on wild animals could provide more information regarding the rickettsiosis enzootic cycle. The aim of this study is to describe the results of a molecular survey of Rickettsia spp. in the Neotropical deer tick, Haemaphysalis juxtakochi Cooley, 1946 (Acari: Ixodidae), from the Brazilian Pampa. Ticks were obtained from 14 road-killed gray brocket deer, Mazama gouazoubira (Artiodactyla: Cervidae), found in nine different municipalities of Rio Grande do Sul state, Southern Brazil. Ticks were processed individually to obtain genomic DNA, and then Rickettsia spp. was investigated using a set of PCR reactions that amplified the rickettsial fragments of the gltA, ompA, and htrA genes. Of the 24 tick samples tested, DNA of Rickettsia parkeri sensu stricto (s.s.) was found in 11 H. juxtakochi specimens collected in two different areas of the Brazilian Pampa. This is the first report of R. parkeri s.s. (the main agent associated with SF in the Uruguayan, Argentinian, and Brazilian Pampa) in H. juxtakochi ticks. These findings indicate that R. parkeri s.s. may be much more common and widely distributed in the Pampa biome than previously assumed. Moreover, H. juxtakochi ticks and gray brocket deer could participate in the potential spillover of R. parkeri s.s. from endemic to non-endemic areas in the South American Pampa.

Abstract
OBJECTIVES Maternal dental periapical infections are associated with preterm birth and intrauterine growth restriction. This study investigates whether the association is mediated through bacterial spread from periapical lesions to placenta (direct pathway) or systemic inflammatory reaction (indirect pathway). MATERIALS AND METHODS We compared birth outcomes in Malawian mothers with and without periapical infection. As markers of a direct pathway, we identified placental bacteria using a 16S rDNA approach and assessed histological evidence of inflammation in the placenta and amniotic membranes. We measured C-reactive protein, alpha-1-acid glycoprotein, and salivary cortisol as markers of an indirect pathway. We used regression models to associate the predictor variables with duration of pregnancy and newborn size. RESULTS Of 1,024 women, 23.5% had periapical infection. There was no association of periapical infection with either bacterial DNA or histological inflammation in placenta or membranes. Periapical infection was associated with C-reactive protein, alpha-1-acid glycoprotein, and cortisol concentrations in a dose-dependent manner at 36 weeks. Addition of alpha-1-acid glycoprotein or cortisol concentration into regression models attenuated the association between periapical infection and pregnancy outcomes. CONCLUSION There was no evidence of direct spread of periapical bacteria to the placenta. Periapical infections and adverse pregnancy outcomes are in part mediated through systemic inflammation.

Abstract
SummaryMultiple ligament injuries of the canine and feline stifle joint which result in luxation are uncommon. Two cats and one dog, that had sustained such a joint injury were surgically treated. A rupture of the cranial and caudal cruciate ligaments, and at least one collateral ligament was observed in all of the three animals. Prosthetic reconstruction was used, as previously described, in combination with a novel technique of intraoperative placement of a temporary trans-articular pin (TTP) to maintain intra-operative anatomical reduction. TTP placement facilitated maintenance of joint alignment during surgical reconstruction and aided appropriate tensioning of the prosthetic sutures, preventing collapse of femorotibial joint compartments. The TTP was removed prior to closure of the joint allowing immediate post-operative joint mobilisation. Based on assessment by their owners, all the animals made a complete recovery. TTP was considered a relatively simple and effective adjunctive aid for surgical treatment of traumatic luxation of the stifle joint.

Abstract
OBJECTIVES Oral malignant melanomas carry a poor-to-guarded prognosis because of their local invasiveness and high metastatic propensity. The Oncept melanoma vaccine is licensed to treat dogs with stage II or III locally-controlled oral malignant melanoma and this retrospective study aimed to assess survival of affected dogs treated with the vaccine in the UK. MATERIAL AND METHODS Medical records of dogs with histopathologically-confirmed oral malignant melanoma that received the vaccine as part of their treatment were evaluated. Survival analyses for potential prognostic factors were performed. RESULTS Sixty-nine dogs were included; 56 dogs, staged I to III, and with previous locoregional therapy, had a median survival time of 455 days (95% CI: 324 to 586 days). Based on Kaplan-Meier survival analysis with associated log-rank testing, no significant prognostic factors were identified for this population. Of the 13 patients with macroscopic disease treated with vaccine alone or in combination therapy, eight showed clinical response. Three patients with stage IV oral malignant melanoma survived 171, 178 and 288 days from diagnosis. CLINICAL SIGNIFICANCE Patients treated with the melanoma vaccine in our study had survival times similar to their counterparts receiving the vaccine in the USA. There were observed responses in patients with macroscopic disease and so the vaccine could be considered as palliative treatment in dogs with stage IV disease.

Abstract
Summary
Here we report the case of a diagnostic and treatment challenge in a four-month old dog from England, presented with one-month history of unproductive cough. Antigen blood test for Angiostrongylus vasorum infection was negative. Thoracic radiographs revealed a generalised bronchointerstitial pattern and bronchoscopy showed moving nematodes in the mucus of the bronchial wall. Additionally, Baermann technique revealed a high burden of larvae per gram of faeces. Morphological and molecular analyses confirmed that they were first stage larvae of Crenosoma vulpis. The infection was firstly treated with a spot-on solution containing 10% imidacloprid + 2.5% moxidectin, but the dog was still positive after 13 days. Therefore, a seven-day course of fenbendazole was prescribed. This represents one of the youngest dogs ever reported naturally infected by C. vulpis. The scant number of reported cases of crenosomosis has led practitioners to consider it as a rare parasitic disease in dogs, delaying a correct and targeted on-time diagnosis. Further studies are needed to perceive the real prevalence of this lungworm and to understand if it is a rare parasite or just rarely diagnosed.

Abstract
Autism spectrum disorders (ASDs) affect as many as 1 in 45 children and are characterized by deficits in sociability and communication, as well as stereotypic movements. Many children also show severe anxiety. The lack of distinct pathogenesis and reliable biomarkers hampers the development of effective treatments. As a result, most children with ASD are prescribed psychopharmacologic agents that do not address the core symptoms of ASD. Autoantibodies against brain epitopes in mothers of children with ASD and many such children strongly correlate with allergic symptoms and indicate an aberrant immune response, as well as disruption of the blood-brain barrier (BBB). Recent epidemiological studies have shown a strong statistical correlation between risk for ASD and either maternal or infantile atopic diseases, such as asthma, eczema, food allergies and food intolerance, all of which involve activation of mast cells (MCs). These unique tissue immune cells are located perivascularly in all tissues, including the thalamus and hypothalamus, which regulate emotions. MC-derived inflammatory and vasoactive mediators increase BBB permeability. Expression of the inflammatory molecules interleukin (IL-1β), IL-6, 1 L-17 and tumor necrosis factor (TNF) is increased in the brain, cerebrospinal fluid and serum of some patients with ASD, while NF-kB is activated in brain samples and stimulated peripheral blood immune cells of other patients; however, these molecules are not specific. Instead the peptide neurotensin is uniquely elevated in the serum of children with ASD, as is corticotropin-releasing hormone, secreted from the hypothalamus under stress. Both peptides trigger MC to release IL-6 and TNF, which in turn, stimulate microglia proliferation and activation, leading to disruption of neuronal connectivity. MC-derived IL-6 and TGFβ induce maturation of Th17 cells and MCs also secrete IL-17, which is increased in ASD. Serum IL-6 and TNF may define an ASD subgroup that benefits most from treatment with the natural flavonoid luteolin. Atopic diseases may create a phenotype susceptible to ASD and formulations targeting focal inflammation of the brain could have great promise in the treatment of ASD.

Abstract
Abstract
Background: Timely detection and treatment of breast cancer patients is important in survival and recurrence. Given disparities in breast cancer outcomes based on socioeconomic status, we examined the time to diagnosis and treatment in a safety net hospital.
Methods: We conducted a retrospective review of all breast cancer patients identified by cancer registry records from 7/1/2010 to 6/30/2012 (n=124). We excluded patients with primary stage IV (n=8) and those with recurrent breast cancer within 5 years of primary diagnosis (n=4). We determined intervals between presentation to diagnosis, diagnosis to first treatment, last surgery to chemotherapy start, and last surgery to radiation start. We used logistic regression to calculate unadjusted odds of receiving timely treatment (< median time) versus more delayed treatment (≥ median time) as a function of age, language, ethnicity, insurance, Charlson co-morbidity index, cancer stage, method of first presentation (screening mammography vs. care provider), symptoms at presentation, and type of surgical treatment.
Results: Of 112 patients, the median age was 59. 42.9% were Hispanic, 29.5% were White, and 24.1% were African American. Clinical stage distribution was 20.0% stage 0, 31.8% stage I, 40.9% stage II, and 8% stage III. 83.9% of patients had surgery, of which 51.1% had breast conservation. The median time from presentation to diagnosis, time from diagnosis to first treatment, and time from surgery to chemotherapy start, fell within recommended intervals (Table 1). The time from last surgery to radiation start was greater than recommended intervals. Variables with significantly increased odds of taking longer than the median time include: stage, method of presentation, language, Charlson index, surgical treatment, ethnicity, symptoms at presentation (Table 2).
Conclusion: Acceptable diagnosis and treatment intervals were obtained for disadvantaged patients, except for time to radiation therapy. Room for improvement exists: focused interventions to facilitate access to radiation therapy, aid providers in accessing imaging more quickly, aid non-English speaking and Hispanic patients could lead to improved breast cancer care.

Abstract
Porphyromonas gingivalis is a bacterium associated with chronic periodontitis that possesses a family of genes encoding hemagglutinins required for heme acquisition. In this study we generated ΔhagB and ΔhagC mutants in strain W83 and demonstrate that both hagB and hagC are required for adherence to oral epithelial cells. Unexpectedly, a double ΔhagB/ΔhagC mutant had less severe adherence defects than either of the single mutants, but was found to exhibit increased expression of the gingipain-encoding genes rgpA and kgp, suggesting that a ΔhagB/ΔhagC mutant is only viable in populations of cells that exhibit increased expression of genes involved in heme acquisition. Disruption of hagB in the fimbriated strain ATCC33277 demonstrated that HagB is also required for stable attachment of fimbriated bacteria to oral epithelial cells. Mutants of hagC were also found to form defective single and multi-species biofilms that had reduced biomass relative to biofilms formed by the wild-type strain. This study highlights the hitherto unappreciated importance of these genes in oral colonization and biofilm formation.

Abstract
BACKGROUND In the UK, the majority of people die in hospital.(1) Community presence is considered to be a significant component to achieving a "good death",(2,3) however many patients die with no/few visitors, spending their last weeks of life isolated or alone. AIM To establish a Volunteer Service and offer: A presence to dying patients. A connexion to the community outside the Hospital. Support to families, unable to visit or emotionally exhausted from their bedside vigil. METHODS The Service was piloted on 6 wards (October 2012-March 2013) within a large NHS Trust, in the North of England. This was followed by a comprehensive evaluation, according to MRC guidance. RESULTS Analysis of the service evaluation indicated that the service was extremely beneficial, meeting its aims in providing an emotional support and spiritual presence to dying patients, and their families. CONCLUSION The Service provides a model of best practice that could be replicated in other Trusts and within other care settings. There are plans to further develop and expand service provision across the Trust. REFERENCES National End of Life Care Intelligence Network.

Abstract
It is widely acknowledged that there is interplay between physical and mental health, with causality in both directions. A common theme across countries is the uncertainty surrounding who should act as gatekeeper for physical health matters in psychiatry. Much of the metabolic monitoring is carried out by psychiatrists who often feel ill equipped to treat medical problems such as abnormal cholesterol or disturbances of glucose metabolism. However many patients do not attend primary care on a regular basis and may not be likely to follow through on referral to primary care. This review aims to examine the interplay between co-morbid physical and mental health conditions, identify the physical health conditions particularly associated with severe affective and psychotic illness and briefly discuss interventions and recommendations in this area. As people with severe mental illness die 10-20 years younger than their peers, with much of this premature mortality due to cardiovascular disease, this topic is emerging as one of great importance amongst clinicians and policymakers internationally.

Abstract
We present a case of type 1 cryoglobulinemia with an underlying hematological malignancy. Unusually, the entire unifying diagnosis was made on the basis of the renal biopsy. Initially, serum cryoglobulin was not identified; repeat samples were positive. It is important to note that there is a significant false-negative rate with laboratory testing for cryoglobulin, due, at least in part, to the specific conditions required for collection and processing. With that in mind, in all cases with strong clinical or histological evidence of cryoglobulin but negative testing, carefully repeated samples should be sent.

Abstract
The mechanism and formation of cancer have always been topics of interest for scientists, even for doctors in ancient times. Nowadays a great role for cancer is played by psychological stress which promotes relevant changes in neuronal activity and gene regulations across the different brain areas. It has been reported by many authors that stress can have an important role in the immune system and may be relevant in the formation of cancer. Our observations, in accordance with other research studies, confirm the importance of the influence of depression, linked to neuroendocrine stress, on the enhancement of cancer pathogenesis by inhibiting anti-tumor immune responses. In this article we review the past and present history of the relationship between cancer and psychology.

Abstract
In Ireland, new bovine tuberculosis (bTB) cases are detected using both field and abattoir surveillance. During field surveillance, an animal may be deemed a 'standard inconclusive reactor' (SIR) to the single intradermal comparative tuberculin test (SICTT) if the bovine response is >2mm, and from 1 to 4mm greater than the avian response. Little is known about the future infection risk posed by SIR animals that pass a subsequent retest, so-called 'transient SIR' (TIR) animals. The objective of this study was to critically evaluate the future bTB status of TIR animals, by examining the future risk of bTB diagnosis over the 4 years following initial SIR diagnosis and clearance at the subsequent retest. The study included all TIRs that were identified as SIRs in 2005 in otherwise free herds at tests with no other reactors at that test and that were clear at the subsequent retest. The analysis was restricted to cows that were neither sold, other than direct to slaughter, nor exported from the herd during the follow up period (to the end of 2009). Five control cows were randomly selected from each study herd. A parametric survival model with shared frailties, to account for clustering within herds, was developed to model time from passing a retest to future bTB diagnosis. The final parametric survival model contained the variables: TIR status in 2005, inconclusive status during the follow-up period, location, herd restricted during the study, time since last restriction within the herd and age. The time ratio for the TIR status variable was significant (p<0.001) indicating that on average the time to diagnosis with bTB for TIRs was 78% shorter compared to the non-TIRs. The frailty term was significant (p<0.001) indicating that animals within some herds were more likely to become reactors compared to other herds. These results have important implications for national policy and future management of TIR animals. Further, private veterinary practitioners and their clients should be aware of the increased risk associated with TIRs.

Abstract
An 11-year-old domestic shorthair cat presented with a six-week history of regurgitation following a dental procedure. Endoscopy identified a single oesophageal stricture in the cervical oesophagus. Stricture reformation occurred following endoscopic balloon catheter dilation on two occasions. Following a third balloon dilation a biodegradable polydioxanone self-expanding stent was placed across the stricture site. Following the implantation the cat was able to eat soft canned food orally without regurgitation. Fluoroscopic examination performed four months after placement indicated that the stent was no longer present and the cervical oesophagus was able to pass boluses of canned food with no signs of obstruction.

Abstract
Autism spectrum disorder is of interest neurochemically because it represents a relatively homogeneous disorder with regard to disease development, abnormal cognitive development and intellectual development disturbance. A consistent finding in autistic children is a high number of mast cells and a high level of serotonin which is also found at elevated concentrations in the urine of autistic patients. In addition, a dysfunction of clinical conditions, such as gastrointestinal and immunological symptoms, is frequently noted in autistic children, however, IgE does not appear to be prevalent in these children but probably an increase of cytokines/chemokines produced by mast cells at an early age may play an important role. Therefore an immune hypothesis, involving also autoimmunity, is one possible pathogenetic mechanism in autism. In conclusion, mast cell activation could contribute to immune and neuroinflammatory abnormalities that are evident in patients with autism spectrum disorders.

Abstract
The tridecapeptide neurotensin (NT) acts in the mammalian brain as a primary neurotransmitter or neuromodulator of classical neurotransmitters. Morphological and functional in vitro and in vivo studies have demonstrated the existence of close interactions between NT and dopamine both in limbic and in striatal brain regions. Additionally, biochemical and neurochemical evidence indicates that in these brain regions NT also plays a crucial role in the regulation of the aminoacidergic signalling. Immune cells, such as lymphocytes, macrophages and mast cells are reported to be activated by neuropeptides, such as neurotensin; this activation leads to cytokine and immunoglobulin production. In addition, neurotensin increases calcium level and the production of nitric oxide. Therefore neurotensin is deeply involved in immunity and inflammation but its real function still remains to be elucidated.

Abstract
Three main types of inflammatory Non-Allergic Rhinitis (NAR) have been defined: NAR infiltrated by eosinophils (NARES), by mast cells (NARMA), and by neutrophils (NARNE). In the absence of studies that investigated the Quality of Life (QoL) in NAR, the present work is aimed at evaluating the Quality of Life of patients with NARES, NARMA, and NARNE. One hundred thirty one (131) NAR patients were prospectively and consecutively evaluated: 54 patients with NARES, 38 with NARMA, and 39 with NARNE. Their history, nasal infiltration and rhinomanometry were characterized, and Quality of Life (using 2 instruments) was evaluated, and associated to clinical and histological features. Quality of Life was significantly different in the 3 groups (p less than 0.001); NARES patients had the worst Quality of Life. Nasal resistances were significantly higher in the NARES group. Significant associations were shown in NARES patients between Quality of Life and nasal function. This study provides the first evidence that Quality of Life is impaired in NAR as well as in allergic rhinitis. Furthermore, Quality of Life impairment differs among the various forms of NAR, and there is a correlation with the cellular infiltrating type.

Abstract
AIMS Multilocus sequence typing (MLST) was used to examine the diversity and population structure of Campylobacter jejuni isolates associated with sporadic cases of gastroenteritis in Australia, and to compare these isolates with those from elsewhere. METHODS AND RESULTS A total of 153 Camp. jejuni isolates were genotyped. Forty sequence types (STs) were found, 19 of which were previously undescribed and 21 identified in other countries. The 19 newly described STs accounted for 43% of isolates, 16 of which were assigned to known clonal complexes. Eighty-eight percent of isolates were assigned to a total of 15 clonal complexes. Of these, four clonal complexes accounted for 60% of isolates. Three STs accounted for nearly 40% of all isolates and appeared to be endemic, while 21 STs were represented by more than one isolate. Seven infections were acquired during international travel, and the associated isolates all had different STs, three of which were exclusive to the travel-acquired cases. Comparison of serotypes among isolates from clonal complexes revealed further diversity. Eight serotypes were identified among isolates from more than one clonal complex, while isolates from six clonal complexes displayed serotypes not previously associated with those clonal complexes. CONCLUSIONS Multilocus sequence typing is a useful tool for the discrimination of subtypes and examination of the population structure of Camp. jejuni associated with sporadic infections. SIGNIFICANCE AND IMPACT OF THE STUDY This study highlights the genotypic diversity of Camp. jejuni in Australia, demonstrating that STs causing disease have both a global and a local distribution evident from the typing of domestically and internationally acquired Camp. jejuni isolates.

Abstract
The coadministration of prescription omega-3-acid ethyl esters (P-OM3) with a statin may present a treatment option for patients with mixed hyperlipidemia. This open-label, randomized, 2-way crossover, drug-drug interaction study evaluated the impact of P-OM3 capsules on plasma simvastatin pharmacokinetics in 24 healthy volunteers. Under fasted conditions, 80 mg simvastatin was administered with or without 4 g P-OM3 for two 14-day periods. After 14 days of dosing to achieve steady state, no significant differences were found in either the extent (AUC(tau)) or rate (Cmax) of exposure to simvastatin or its major beta-hydroxy metabolite after coadministration of P-OM3 with simvastatin compared with administration of simvastatin alone. At steady state, the coadministration of P-OM3 capsules did not appear to affect the pharmacokinetics of simvastatin tablets. The combination of P-OM3 capsules and simvastatin appeared to be well tolerated.

Abstract
Few studies have investigated personality and psychopathological profiles associated to the choice of university education. Our study examined students from four faculties of Turin University, in Turin, Italy (Medicine, Engineering, Education, Law), comparing sociodemographic features, personality characteristics and psychiatric symptoms. A heterogeneous group of 1,323 students were assessed using a semistructured interview, the Personality Diagnostic Questionnaire-Revised (PDQ-R), and the Symptoms Checklist 90 (SCL-90). Statistical analysis included four logistic regression models, each fitted for one faculty, considering the other three as a control group. Associations were found in Medical and Engineering students concerning type of high school, school final score, and father?s socioeducational level. Factors associated with students of Law and Education included socioeducational characteristics, but stronger correlations were seen with PDQ-R personality scales and SCL-90 symptom clusters. In conclusion, four different profiles were identified. Medicine was not significantly related to personality and psychiatric factors. Engineering was related to male gender, choice of technical high school and father?s social level. Law was related to female gender and narcissistic personality profile. These data may be useful for counseling activities addressed to high school and university students.

Abstract
Beta2-glycoprotein I (beta2GPI) is a plasma protein suspected to have a role in inhibition of thrombosis. This suspicion is reinforced by the observation that beta2GPI is the major target for autoantibodies in the antiphospholipid syndrome. However, little is known about its circulating levels in common thrombotic diseases or inflammation. We measured beta2GPI levels in 344 healthy controls, 58 normal pregnancies, 102 patients with non-haemorrhagic stroke, 121 patients with acute coronary syndrome and 200 patients with elevated C-reactive protein (CRP). In healthy individuals, we found a strong positive correlation between age and beta2GPI concentration (r = 0.274, P < 0.001) and that beta2GPI levels fall significantly after the eighth week of pregnancy (P = 0.002). We also found significantly reduced levels of beta2GPI in patients with stroke and in elderly patients with myocardial syndrome (P = 0.013 and 0.043). However, in neither group did beta2GPI levels change in the following six months, suggesting that the reduced levels were not a transient post-event phenomenon. In patients with inflammation, beta2GPI levels showed a significant negative correlation with CRP (r = -0.284, P < 0.001) and positively correlated with albumin and transferrin (r = 0.372 and 0.453, respectively with P < 0.001 for both). Furthermore, the largest reduction in beta2GPI levels occurred in patients with the highest CRP values (P < 0.001).

Adrenoceptor blockade alters plasma gelatinase activity in patients with heart failure and MMP-9 promoter activity in a human cell line (ECV304). Pharmacol Res 2006; 54:57-64. [PMID: 16574429 DOI: 10.1016/j.phrs.2006.02.006] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2006] [Revised: 02/17/2006] [Accepted: 02/17/2006] [Indexed: 10/25/2022]
Abstract
This study assessed the effects of short-term adrenoceptor blockade on plasma matrix metalloproteinase (MMP) activity in patients with heart failure, and the ability of adrenoceptor stimulation to modulate matrix metalloproteinase-9 (MMP-9) promoter activity in vitro. Patients with heart failure received standard therapy or standard therapy plus carvedilol. Plasma MMP activity was determined by zymography and tissue inhibitor (TIMP-1) expression was measured by immunoblotting. MMP-9 promoter activity was assessed in transfected ECV304 cells following exposure to isoprenaline or phenylephrine in the absence or presence of either propranolol or prazosin. In patients with heart failure, carvedilol attenuated the increase in proMMP-9 activity observed at 4 and 12 weeks in non-beta-blocker-treated patients (44.0 +/- 4.9 AU versus 60.8 +/- 6.7 AU; P < 0.05). Although TIMP-1 expression was unaltered, the MMP-9:TIMP-1 ratio was lower in those receiving carvedilol at 4 and 12 weeks (0.54 +/- 0.07 versus 1.04 +/- 0.17; P < 0.05). Isoprenaline transiently increased MMP-9 promoter activity after 4 h exposure (80.6 +/- 14.8-fold; P < 0.001) before returning to baseline. The response to isoprenaline was prevented by propranolol (P < 0.01). Phenylephrine caused a biphasic increase in MMP-9 promoter activity, with the greatest increase occurring at 24 h (23 +/- 3.7-fold) compared to baseline. This response was unaffected by co-incubation with prazosin. In conclusion, treatment with a mixed alpha1/beta-adrenoceptor antagonist attenuates MMP activity and tips the degradative balance to a less degradative phenotype in heart failure patients. Furthermore, adrenoceptor stimulation increases MMP-9 promoter activity, which is inhibited by beta- but not alpha-adrenoceptor blockade. Therefore, mixed adrenoceptor blockade may reduce remodeling in heart failure as a direct consequence of a beta-adrenoceptor-mediated reduction in MMP-9 transcription.

Abstract
The clinical, radiographic, magnetic resonance imaging (MRI), surgical and pathological findings related to an osteochondral lesion of the sacrum in a mastiff dog are described. The dog showed chronic signs of pain in its pelvic limbs. Radiography revealed a triangular mineralised opacity at the craniodorsal aspect of the sacrum consistent with sacral osteochondrosis. A T2-weighted spin-echo MRI revealed dorsal and lateral compression of the cauda equina. The osteochondral fragment was removed via a dorsal laminectomy, and the clinical signs resolved. Histological abnormalities in the fragment were consistent with a diagnosis of osteochondrosis.

Abstract
BACKGROUND Using an empirically derived instrument to reduce the assessor bias inherent in structured diagnostic interviews, we sought to re-examine and validate the putative comorbidity between Obsessive Compulsive Disorder (OCD) and Attention-Deficit/Hyperactivity Disorder (ADHD) in children and adolescents. METHOD We examined the correlation between Child Behavior Checklist (CBCL) syndrome, competence, and composite scores in children with: 1) OCD plus ADHD (OCD + ADHD), N = 47; 2) OCD without comorbid ADHD (OCD), N = 33; 3) ADHD without comorbid OCD (ADHD) N = 43; and 4) comparison controls recruited from general pediatric clinics,N = 32. RESULTS CBCL findings in our ADHD children were similar to previous findings reported in ADHD youth, irrespective of the presence or absence of comorbid OCD. Comorbid youth generally had additive scores on the CBCL scales, reflecting the independent contribution of symptomatic and functional impairment from each disorder. CONCLUSION These findings suggest that when ADHD-like symptoms are seen in OCD youth, they reflect a true comorbid state of OCD plus ADHD. The CBCL may provide a rapid assessment tool to identify comorbid ADHD in OCD youth.

Abstract
Low n-3 polyunsaturated fatty acid (PUFA) status may be associated with neuro-degenerative disorders, in particular Alzheimer's disease, which has been associated with poor dietary fish or n-3 PUFA intake, and low docosahexaenoic acid (DHA) status. The present case-control study used an established biomarker of n-3 PUFA intake (serum cholesteryl ester-fatty acid composition) to determine n-3 PUFA status in patients with Alzheimer's disease, who were free-living in the community. All cases fulfilled the National Institute of Neurological and Communicative Disorders and Stroke and Alzheimer's Disease and Related Disorders Association criteria for Alzheimer's disease. Detailed neuropsychological testing and neuroimaging established the diagnosis in all cases. The subjects (119 females and twenty-nine males) aged 76.5 (SD 6.6) years had a clinical dementia rating (CDR) of 1 (SD 0.62) and a mini mental state examination (MMSE) score of 19.5 (SD 4.8). The control subjects (thirty-six females and nine males) aged 70 (SD 6.0) years were not cognitively impaired (defined as MMSE score <24): they had a mean MMSE score of 28.9 (SD 1.1). Serum cholesteryl ester-eicosapentaenoic acid and DHA levels were significantly lower (P<0.05 and P<0.001 respectively) in all MMSE score quartiles of patients with Alzheimer's disease compared with control values. Serum cholesteryl ester-DHA levels were progressively reduced with severity of clinical dementia. DHA levels did not differ in patients with Alzheimer's disease across age quartiles: all were consistently lower than in control subjects. Step-wise multiple regression analysis showed that cholesteryl ester-DHA and total saturated fatty acid levels were the important determinants of MMSE score and CDR. It remains to be determined whether low DHA status in Alzheimer's disease is a casual factor in the pathogenesis and progression of Alzheimer's disease.
