Seasonal dynamics of Pneumocystis carinii in the field vole, Microtus agrestis, and in the common shrew, Sorex araneus, in Finland
Seasonal dynamics of Pneumocystis carinii in the field
vole, Microtus agrestis, and in the common shrew, Sorex araneus,
were investigated in southern and central Finland by microscopical examination
of methenamine silver-stained tissue
sections. In both host species at both localities the number of P.
carinii cyst forms was highest in late autumn (November).
In S. araneus, prevalence was higher than in M. agrestis
during all seasons. None of the animals was heavily infected or
apparently ill, and neither species showed any extrapulmonary dissemination.
In this study covering an increase phase and
4 peak host-density phases of the vole cycle, the occurrence of P.
carinii seemed to be related to the population density
of M. agrestis.</jats:p
Is bilingualism associated with enhanced executive functioning in adults? A meta-analytic review.
This article was published Online First March 1, 2018.
Supplemental materials: http://dx.doi.org/10.1037/bul0000142.suppBecause of enduring experience of managing two languages, bilinguals have been argued to develop superior executive functioning compared with monolinguals. Despite extensive investigation, there is, however, no consensus regarding the existence of such a bilingual advantage. Here we synthesized comparisons of bilinguals’ and monolinguals’ performance in six executive domains using 891 effect sizes from 152 studies on adults. We also included unpublished data, and considered the potential influence of a number of study-, task-, and participant-related variables. Before correcting estimates for observed publication bias, our analyses revealed a very small bilingual advantage for inhibition, shifting, and working memory, but not for monitoring or attention. No evidence for a bilingual advantage remained after correcting for bias. For verbal fluency, our analyses indicated a small bilingual disadvantage, possibly reflecting less exposure for each individual language when using two languages in a balanced manner. Moreover, moderator analyses did not support theoretical presuppositions concerning the bilingual advantage. We conclude that the available evidence does not provide systematic support for the widely held notion that bilingualism is associated with benefits in cognitive control functions in adults.The study was financially supported by Academy of Finland (grant 288880),

Training Staff in Long-Term Care Facilities-Effects on Residents' Symptoms, Psychological Well-Being, and Proxy Satisfaction
Context. Long-term care facility (LTCF) residents have unmet needs in end-of-life and symptom care. Objectives. This study examines the effects of an end-of-life care staff training intervention on LTCF residents' pain, symptoms, and psychological well-being and their proxies' satisfaction with care. Methods. We report findings from a single-blind, cluster randomized controlled trial featuring 324 residents with end-of-life care needs in 20 LTCF wards in Helsinki. The training intervention included four 4-hour educational workshops on palliative care principles (advance care planning, adverse effects of hospitalizations, symptom management, communication, supporting proxies, challenging situations). Training was provided to all members of staff in small groups. Education was based on constructive learning methods and included participants' own resident cases, role-plays, and small-group discussions. During a 12-month follow-up we assessed residents' symptoms with the Edmonton Symptom Assessment Scale (ESAS), pain with the PAINAD instrument and psychological well-being using a PWB questionnaire. Proxies' satisfaction with care was assessed using the SWC-EOLD. Results. The change in ESAS symptom scores from baseline to 6 months favored the intervention group compared with the control group. However, the finding was diluted at 12 months. PAINAD, PWB, and SWC-EOLD scores remained unaffected by the intervention. All follow-up analyses were adjusted for age, gender, do-not-resuscitate order, need for help, and clustering. Conclusion. Our rigorous randomized controlled trial on palliative care training intervention demonstrated mild effects on residents' symptoms and no robust effects on psychological well-being or on proxies' satisfaction with care.

Comparison of Finnish meat inspection records and average daily gain for cattle herds differing in Mycoplasma bovis test-status
Detecting Mycoplasma bovis on cattle farms represents a challenge in the absence of an outbreak or cases of M. bovis mastitis, yet identification of an infection is essential to control the spread of the disease successfully. The objectives of this study were: (1) to determine whether meat inspection records can aid identification of cattle farms supporting M. bovis infection, and (2) to compare the average daily weight gain estimated from carcass weight for cattle originating from farms differing in M. bovis test-status. Meat inspection records were collected from two abattoirs in 2015; 80 677 animals in total. All the dairy and mixed breed cows and bulls used for meat production were categorized according to known M. bovis infection status of the farms from which the cattle were derived; positive, contact or control farms. The associations between animals from different M. bovis categories and lung lesions of bulls and cows (pneumonia and pleuritis), identified during meat inspection, and estimated average daily gain (ADG) of bulls, were investigated. The odds ratios for lung lesions, especially pleuritis, were higher in M. bovis test-positive or contact farms compared with control farms. Additionally, odds ratios for pleuritis were higher among animals from M. bovis test-positive farms and animals from contact slaughtering farms originating from M. bovis-free rearing farms. Bulls originating from M. bovis test-positive farms had higher estimated average daily gain than cattle from control farms. Meat inspection records can be used alongside other methods to detect M. bovis-positive farms where M. bovis causes lung lesions. (C) 2019 The Authors. Published by Elsevier Ltd.Peer reviewe
Adverse Life Events: Do Home Care Clients Have Resources for Mastering Them?
Objectives: Research on life stressors and adverse life events has a long tradition.
Few studies have addressed this topic in connection to very old people. Life stressors,
especially major life stressors (MLSs) experienced by clients of home care services in the
community have rarely been the subject of studies. Considering this gap, we investigated
the prevalence of MLSs in home care clients. We examined the effects that MLSs have
on their mood and health status as well as the impact of clients’ social resources on
MLSs and their outcomes.
Method: We used assessment data from 2,884 home care clients in six European
countries. The methodological basis was the comprehensive and standardized interRAI
Home Care Assessment (interRAI HC).
Results: Fifteen point four percent of the sample—that consisted of women and men
with an average age of 82.89 years–experienced an MLS in the last 6 months before the
assessment. They were more depressed than persons without these experiences, and
their health status indicated a higher level of instability and deterioration. At reassessment
after 6 months, the situation changed. Despite the fact that both outcomes of the MLSs,
depression and health status became worse in the reassessment-sample, home care
clients without MLS were more affected by the worsening, especially that of depression.
The expected buffering impact of social resources was low.
Discussion: Although this study worked with limited information on MLSs, it could
contribute to closing various knowledge gaps. The study shows that the MLSs represent
a prevalent problem in a population of home care clients and that this problem
has negative consequences for their mood and the stability of their health status.
Furthermore, this research took up the situation of very old and vulnerable adults,
who have previously rarely been considered in studies on major critical life events
and stressors.
Conclusion and Research Perspective: Future research on MLSs has to take
up the issue of the time passage between the MLS and the impact on health and
well-being of individuals dependent on care. It has to determine immediate as well as later
consequences and identify those factors that are appropriate to reduce the MLS-effects
on very old people dependent on care
Working memory training restores aberrant brain activity in adult attention-deficit hyperactivity disorder
The development of treatments for attention impairments is hampered by limited knowledge about the malleability of underlying neural functions. We conducted the first randomized controlled trial to determine the modulations of brain activity associated with working memory (WM) training in adults with attention-deficit hyperactivity disorder (ADHD). At baseline, we assessed the aberrant functional brain activity in the n-back WM task by comparing 44 adults with ADHD with 18 healthy controls using fMRI. Participants with ADHD were then randomized to train on an adaptive dual n-back task or an active control task. We tested whether WM training elicits redistribution of brain activity as observed in healthy controls, and whether it might further restore aberrant activity related to ADHD. As expected, activity in areas of the default-mode (DMN), salience (SN), sensory-motor (SMN), frontoparietal (FPN), and subcortical (SCN) networks was decreased in participants with ADHD at pretest as compared with healthy controls, especially when the cognitive load was high. WM training modulated widespread FPN and SN areas, restoring some of the aberrant activity. Training effects were mainly observed as decreased brain activity during the trained task and increased activity during the untrained task, suggesting different neural mechanisms for trained and transfer tasks.Peer reviewe
Training nursing home staff to improve residents' end-of-life care : design and baseline findings from a randomized controlled trial
Key summary pointsAimWe present the design, intervention, baseline findings and feasibility of a randomized, controlled trial examining the effectiveness of staff training in palliative care on nursing home residents' hospitalizations and health-related quality-of-life.FindingsMost staff members participated in the training sessions and they gave good feedback. Our patient groups are fairly well balanced in their characteristics.MessageIf our further trial shows patient-related benefits, we will have a well-defined model for improving palliative care in nursing homes. AbstractPurposeWe aim to describe the design, educational intervention, baseline findings and feasibility of our training intervention. Our trial will aim to improve the residents' health-related quality of life (HRQOL) and to reduce unnecessary hospitalizations.MethodsWe recruited 340 residents from 20 nursing home wards in Helsinki, and they were randomized into intervention and control groups. At baseline, all the participants were assessed for demographics, medical history, medication, HRQOL, symptoms, hospitalizations, advance care plans, and proxies' satisfaction with care. The staff in the intervention wards were offered four 4-h educational sessions on the principles of palliative care (advance care planning, the adverse effects of hospitalizations, symptom management, communication, giving support to proxies and challenging situations). The sessions were based on constructive learning methods and patient cases.ResultsThe mean age of residents was 84years and 76% were women. The intervention and control groups did not differ with respect to demographics, terminal diseases, comorbidities, nutritional status, cognition or the use of palliative medication. However, the control residents were more likely to be bed-bound and to have a do-not-resuscitate order on their medical chart. Of about 180 staff members, 132 completed the educational intervention. The discussions in the training sessions were lively and the participants gave an overall rating of 4.6/5 for the education.ConclusionsWe have successfully randomized nursing home wards in this trial and completed staff training with very positive feedback. If our trial shows resident-related benefits, we will have a well-defined model for improving palliative care in nursing homes.

Centralized repeated resectability assessment of patients with colorectalliver metastases during first-line treatment : prospective study
Y Background: Metastasectomy is probably underused in metastatic colorectal cancer. The aim of this study was to investigate the effect of centralized repeated assessment on resectability rate of liver metastases. Methods: The prospective RAXO study was a nationwide study in Finland. Patients with treatable metastatic colorectal cancer at any site were eligible. This planned substudy included patients with baseline liver metastases between 2012 and 2018. Resectability was reassessed by the multidisciplinary team at Helsinki tertiary referral centre upfront and twice during first-line systemic therapy. Outcomes were resectability rates, management changes, and survival. Results: Of 812 patients included, 301 (37.1 per cent) had liver-only metastases. Of these, tumours were categorized as upfront resectable in 161 (53.5 per cent), and became amenable to surgery during systemic treatment in 63 (20.9 per cent). Some 207 patients (68.7 per cent) eventually underwent liver resection or ablation. At baseline, a discrepancy in resectability between central and local judgement was noted for 102 patients (33.9 per cent). Median disease-free survival (DFS) after first resection was 20 months and overall survival (OS) 79 months. Median OS after diagnosis of metastatic colorectal cancer was 80, 32, and 21 months in R0-1 resection, R2/ablation, and non-resected groups, and 5-year OS rates were 68, 37, and 9 per cent, respectively. Liver and extrahepatic metastases were present in 511 patients. Of these, tumours in 72 patients (14.1 per cent) were categorized as upfront resectable, and 53 patients (10.4 per cent) became eligible for surgery. Eventually 110 patients (21.5 per cent) underwent liver resection or ablation. At baseline, a discrepancy between local and central resectability was noted for 116 patients (22.7 per cent). Median DFS from first resection was 7 months and median OS 55 months. Median OS after diagnosis of metastatic colorectal cancer was 79, 42, and 17 months in R0-1 resection, R2/ablation, and non-resected groups, with 5-year OS rates of 65, 39, and 2 per cent, respectively. Conclusion: Repeated centralized resectability assessment in patients with colorectal liver metastases improved resection and survival rates.Peer reviewe
